Same sex marriage Essay Example | Topics and Well Written Essays - 1000 words

Same sex marriage - Essay ExampleTherefore, in regards to marriage, the Biblical program line holds that a man shall leave his father and mother and be joined with his wife, forming one flesh (Genesis. 224). From the Christian teachings, it is appargonnt that God created man and woman to enjoy hetero cozy sexual relationship, in the institution of marriage. This paper discusses reasons why very(prenominal) sex marriages should not be legalized. Christian teachings are replete with many a(prenominal) incidents of deviant sexual behaviors including sodomy, incest, bestiality, rape, pedophile among others. The Bible documents Gods objection to same sex through Lot in Genesis 19 3-14. harmonise to Genesis 19, Lot a resident Sodom was one day approached by two men who wanted to surrender same sex with the Lots visitors. The man wanted to sodomize guests in Lots house so that they could save Sodom and Lots household from an imminent destruction. However, Lot rejected their demand and instead, he offered his two virgin daughters to the men. God came to the rescue of Lot and his family before the men could break his house and have sex with Lots daughters. That very night, God guided Lot and his family escaped to safer place. Sodom and Gomorrah was destroyed the following day, by falling fire and burning sulfur (Genesis, 19, 27). It is worth noting that God abhorred same sex and other deviant sexual behaviors in Sodom that He ordered Lot and his wife not to look cover to the city as they fled to a safe place that God ordered them to flee to. However, Lots wife did not heed Gods command and when she turned back to face Sodom, she became a salt pillar (Genesis 19 28). From the religious point of view, it is apparent that same sex marriage and sex is forbidden. In Christianity, the catholic style is particularly intolerant of the union between same sex couples in a marriage. According to Catechism of the Catholic Church (1613), homosexual actions are regarded as pe r se disordered because they contradict with the natural law, inhabiting the gift of life through sexual intercourse. In addition, homosexual actions do not arise from genuine affection and sexual compatibility. In this case, the church recommends that under no circumstances should homosexuality be permitted in the fiat. Therefore, the church argues that legalizing same sex marriage would be harmful to the society (Catechism of the Catholic Church, 1613). In context to family system and same sex marriage, many studies on marriages have established that families made of heterosexual couples are happier, wellnessier and have better economic standing (Linda and Maggie, 2001). Moreover, empirical studies have established that mateless women are more likely to die than married women are, while the probability of unmarried man dying is five times to that of their married counterparts of the same age (Howard and Gary 1995). In this respect, marriage is a key public health issue, which re sults to adverse health effects if it is not established on the right foundation. In the family system, Yuanreng and Noreen (1990) argue that heterosexual marriage results into complementarities, that is absent in same sexual marriages. There are many differences between men and women and these diversities are complementary. These differences have a profound spiritual and physical importance and without complementarity between man and women,

In the eyeball of the slaveholders, slave women were not mothers at all. They were merely instruments guaranteeing the growth of the slave labor force. They were classified as breeders, animals as opposed to mothers. Hence, their infant children could be sold outside(a) like calves from cows.

The clubs clothing and shoe designs typically feature EssayAdidas was founded in 1948 by Adolf Dassler, pursuance the split of Gebrder Dassler Schuhfabrik between him and his older brother Rudolf. Rudolf later established Puma, which was the early rival of Adidas. Registered in 1949, Adidas is currently base in Herzogenaurach, Germany. Puma is also based in Herzogenaurach.The play alongs clothing and shoe designs typically feature three parallel bars, and the same motif is incorporated into Adidass current official logo.The company revenue for 2012 was listed at 14.48 billion.HistoryGebrder Dassler SchuhfabrikChristoph Von Wilhelm Dassler was a worker in a shoe factory, while his wife Pauline ran a small laundry in the Bavarian t causeship of Herzogenaurach, 20 km (12. 4 mi) from the city of Nuremberg. After leaving school, their son, Rudolf Rudi Dassler, joined his father at the shoe factory. When he returned from fighting in World struggle I, Rudolf received a management position at a porcelain factory, and later in a leather wholesale business in Nuremberg.Adolf Adi Dassler started to produce his own sports shoes in his mothers wash kitchen in Herzogenaurach, Bavaria after his return from World War I.In July 1924, his brother Rudolf returned to Herzogenaurach to join his younger brothers business, which became Gebrder Dassler Schuhfabrik (Dassler Brothers Shoe Factory) and prospered. The geminate started the pretend in their mothers laundry,65 notwithstanding, at the time, electricity supplies in the town were unreliable, and the brothers sometimes had to use pedal power from a stationary bicycle to run their equipment.By the 1936 Summer Olympics, Adi Dassler drove from Bavaria on one of the worlds first motorways to the Olympic village with a suitcase full of spikes and persuaded U.S. sprinter Jesse Owens to use them, the first sponsorship for an African American. Following Owenss drop binding of four gold medals, his success cemented the goo d reputation of Dassler shoes among the worlds most famous sportsmen. Letters from around the world landed on the brothers desks, and the trainers of other issue teams were all interested in their shoes. Business boomed and the Dasslers were selling 200,000 pairs of shoes each year before World War II. World War II and company splitBoth brothers joined the Nazi Party, but Rudolf was slightly closer to the party than Adolf. During the war, a growing rift between the pair reached a breach point after an Allied bomb attack in 1943, when Adi and his wife climbed into a bomb shelter that Rudolf and his family were already in The dirty bastards are back again, Adi said, referring to the Allied war planes, but Rudolf was convinced his brother meant him and his family.9 After Rudolf was later picked up by American soldiers and accused of being a member of the Waffen SS, he was convinced that his brother had turned him in.The Dassler factory, used for production of anti-tank weapons during the war, was nearly destroyed by US forces in April 1945, but was spared when Adi Dasslers wife, Kthe, convinced the GIs that the company and its employees were plainly interested in manufacturing sports shoes. American occupying forces subsequently became major buyers of the Dassler brothers shoes.The brothers split up in 1947, with Rudi forming a new firm that he called Ruda from Rudolf Dassler, later rebranded Puma, and Adi forming a companyformally registered as Adidas AG from Adi Dassler on 18 August 1949. Although it is popularly claimed that the name is an acronym for All Day I Dream About Soccer, that phrase is a backronym the name is actually a portmanteau formed from Adi (a nickname for Adolf) and Das (from Dassler).

Charles Dickens most famous Bildungsroman novel Essay Example for Free

Charles Dickens most famous Bildungsroman novel EssayHow Does Dickens Presentation of photograph as a young boy contrast to Pip as an Adult?Great Expectations is one of Charles Dickens most famous Bildungsroman novel. This story is serialised in journals from 1860 1861. It was published chapter at a time therefore would leave ein truth chapter at a cliff-hanger.Due to this novel being published in journals it made this semi-autobiographical news report available to the mass of people soaring its popularity.The main theme of this novel is associated with the main factors of Victorian era Being Gentlemen nurture and Crime and Punishment. Dickens was a social observer and would therefore base his narratives on his concerns for the social laws. Great Expectations was an example of this. This story is based on Pip, the main character, and how his life changes as he comes into possession of a lot of money from an unknown benefactor breaking the wall of social mobility on his way t o become a Gentleman.The whole stress shows the retrospective view of Pip looking back on his life. Furthermore most of the events experience by Pip could also be his past experiences. This is wherefore Great Expectations is Charles Dickens most semi-autobiographical piece of writing.This general aim of this essay is to describe the way Pip was presented as a young boy and subsequently on in his life by this worldwide known author, Charles Dickens.The key scenes in this novel which will be analysed in detail. The chosen key scenes ar chapters 1-8 where Pip is growing up as a young kid and ahs his first encounter with the convict. The significance of these chapters is that it shows Pips peasanthood and also describes his first meeting with Magwitch, who plays a huge role in this novel.The central point of this report will be foc apply on chapter 27-38. This shows Pip as a young gentleman. This is very vital as it shows the way Pip has changed from his childhood ways. In these ch apters it shows when Pip is reunited with his benefactor.The Last key scenes will be chapter 57 and 58. This is when Pip is comes together with Joe hoping to calculate to Biddy. The significance of this is that Joe is going to get married to Biddy therefore Pips reaction to this news is very interesting.Pip was bought up an orphan. The only living family member of Pip was his sister Mrs Joe Gargery. My first fancies regarding what they were like were unreasonably derived from their tombstones This quotation emphasis the fact that Pip was an orphan who had never seen his parents and is an example of dual narrative as it is quite humorous but also sad at the same time. At the beginning of the play Dickens makes the readers fell sympathetic towards Pip. This makes the readers like Pip throughout the story no matter what he does.In the Victorian Era being an orphan was very common. It meant they had no prospects for the future, would be illiterate and would therefore fade a very poor life. They would usually be homeless or taken in by gentlemens to be their slaves. I was at that time small for years and not very strong. This quotation shows that Pip had a lack of prospects which emphasised he came from a poor background. The term undersized could be used for physical terms but also could be used that he had no say in the community as he was a child and he had no say generally as him and his family were very poor.Charles Dickens reversed these points about a poor person and made social mobility come-at-able for Pip.At the beginning of the narrative Pip is a naive young boy who has no knowing of the outside world. Most of this is due to being brought up without education. Education in that era was very important as only the rich could afford it. This immediately brought up the aspect of class issues in this novel. Education led to people being in a higher social group to those who werent educated and possibly shaped their future.Pip suffered abuse from many peo ple. He was bought up by hand by his sister Mrs Joe. She had a reputation for this. This showed that Pip was brought with discipline and wouldnt dare to do a thing wrong as he would get punished for this. Another quotation that explains that Mrs Joe beats Pip to teach him manners and discipline is Be grateful boy to them which bought you up by hand. Whats worse shes got the tickler with her, this quotation shows how much Pip feared the tickler and getting beaten by Mrs Joe.As well as receiving physical abuse from Mrs Joe he received verbal abuse from many family friends such as Mr Pumblechook and also Estella. It was from the Victorian times that the reflexion Children should be seen but not heard was created. This saying applied to Pip. Many guttural sounds were used to describe the abuse that was inflicted upon Pip such as rampage. This emphasises the un-human like behaviour of Mrs Joe towards Pip.

Minireview of A Study Essay Example for Free

Minireview of A Study EssaySynaptic transmission in craniate neuromuscular junctions forms the basis of this study. The communication between neurons in the scatter consciousnessed system occurs largely due to neurotransmitter release at the synapses. Messages on the various significant nervous system functions are coordinated through the synaptic junctions and the release of neurotransmitters. Ryanodine receptors are found in the somata of the Purkinje cells, ring cells and pre-synaptic terminals of specific synapses and terminals of basket cells. atomic number 20 in the extracellular fluid triggers the neurotransmitter release. Now it is understood that pre-synaptic stores could participate in this same function. Ryanodine- fond stores of atomic number 20 also play a role.The quantum is the amount of extemporaneous signals occurring in the absence of pre-synaptic follow up potentials and is equivalent to the release of one neurotransmitter vesicle (Katz, 1969). The swea r out potentials are called miniature currents. For central synapses in the brain, large miniature currents are believed to arise from the release of more neurotransmitter or presynaptic vesicles and in the range of several quanta (Bekkers, 1994). Yoshidas study (1994) revealed that these multivesicular miniature events could actually be tetrodotoxin-resistant action potentials in the pre-synaptic terminals.Other researchers have tried to formulate the phenomenon from another angle, using the presence of intracellular calcium stores in the pre-synaptic terminals. Nakanishi et al localized inositol triphosphate receptors in the neural tissue of the developing and adult mouse brain (1991). These were immunolocalised in the pre-synaptic terminals of the deep cerebellar nuclei and the retina of the eyes. Naritas studies (1998, 2000) revealed the action of ryanodine- smooth calcium stores at the frog neuromuscular junctions.It was discovered that agents which influence the ryanodine-se nsitive Calcium stores also increased the intracellular Calcium in the pre-synaptic cells and regulated acetyl choline release during high relative frequence stimulation. Mothet et al (1998) studied the action potentials at the pre-synaptic terminals of the buccal ganglia in Aplysia. They indicated that ryanodine inhibited go the pre-synaptic injection of Cyclic ADP Ribose augmented the action potential evoked release of acetyl choline at synapses. Studies also showed that caffeine with or without ryanodine modifies Calcium stores at the pre-synaptic terminals in autonomic ganglia (Peng, 1996 Smith et al, 1996) and in photoreceptors (Krizaj, 1999). Studies on hippocampal pyramidal cells have shown thatCaffeine or thapsigargin influences the frequency of miniature IPSCs.Making an assumption, from prior studies described above, that spontaneous Calcium release from pre-synaptic Calcium stores may provide the synchronisation mechanism that causes multivesicular miniature IPSCs and t he fact that such a hypothesis has not been tested consistently previously, the authors have taken up this topic for their study on cerebellar interneuron Purkinje cells.This StudyMethodsExperiments were conducted on the sagittal cerebellar slices of decapitated rats aged 10-14 days of age. During the experimental recordings, the slices were perfused in saline containing prescribed concentrations of NaCl, KCl, Na H2PO4, NaHCO3, CaCl2, MgCl2 and glucose with 955 mixture of oxygen and carbon dioxide. Experiments were make at room temperature.For tight-seal whole-cell recordings, pipettes filled with a tooth root of appropriate concentrations of CsCl, MgCl2, HEPESCs, BAPTA-Cs (Molecular Probes, Eugene, Oregon), CaCl2, Na-GTP and Na-ATP and of pH 7.3 were used. Capacitance cancellation and series resistance compensation had been done. Kynurenic acid had been added to the extracellular answer to block the inotropic gluatamate receptors. TTX was present in the solution for all recordi ngs.The calcium free solutions were prepared by leaving out Calcium and adding EGTA Na.Membrane potential was maintained at -60mV and the current was filtered at1.5-2 kHz. Sampling was done always with brief interruptions. Detection and analysis were done using the IGOR-Pro programming environment. In experimentsneeding a Calcium channel blocker, cytochrome was added to the external solution.The toxin was prepared while the ryanodine was purchased.Testing the CalciumThe Calcium in the basket cells were tested using the Two-photon laser scanningFluorescence microscopy. For studying the action potential-evoked calcium increases, bicuculline was added to the external solution and the calcium sensitive investigate Oregon unfledged was put into the pipettes. Scans were done and pulses were applied at the end of each 8th scan. This was repeated every minute in external solution which contained salinein order to get a baseline. The external solution was then varietyd to the solution con taining ryanodine and recording proceeded for another 15 minutes. Another set of recordings were done with external solution not having calcium but having EGTA Na.The internal solution also had EGTA and Cs instead of K as the main cation.The resolutions in instinctive Calcium transients also were recorded using molecular probes in the external solution. A pseudo line scan was also done. For immunocytochemistry, a rabbit polyclonal anti-serum was raised(a) to the 16 amino-acids found in all mammals. A C terminal cysteine enabled conjugation to haemocyanin. The conjugated peptide was used to immunize rabbits. Then the ELISA confirmed the specificity. The sarcoplasmic and endoplasmic reticulum microsomes derived from theskeletal muscle, cardiac tissue, whole brain and cerebellum were used for immunoblot analysis.Effects of external Calcium concentration.Large bountifulness miniature IPSCs in cerebellar Purkinje cells were found sensitive to extracellular Calcium. With calcium free solution, the mIPSC frequency fell suddenly to half the control level. Continued exposure to the low level of external calcium caused the frequency of mIPSC to continue declining but at a slower rate. On washing after(prenominal) this, the frequency recovered and reached its initial level. The amplitude of the mIPSCs on the other drop dead showed a steady decline all through and no recovery on washing.With high levels of Calcium, the frequency of the mIPSCs increased rapidly and significantly. The change in amplitude varied from no response to a minimal increase. The inference was that Calcium strongly influenced mIPSCs in the Purkinje cells though frequency and amplitude were differently affected. The rapid change in frequency was interpreted as the reaction of intracellular Calcium to external Calcium changes. The slow change in amplitude was considered due to the extracellular influence on the pre-synaptic stores. The prolonged extracellular calcium removal could have caused s elective elimination of large amplitude miniature IPSCs.Repeating with a calcium-free solution, some large amplitude miniature IPSCs were seen again. Then there was a sudden drop and then the amplitudes reduced to become concurrent with the control and the IPSCs were also less. The reducing seen when external Calcium was removed was not due to post-synaptic modifications.On returning to the calcium-rich solution, a slight recovery of both amplitude and frequency occurred. Paired school-age childs t-tests indicate significant changes in mean amplitude and frequency between mIPSCs recorded during a 3-min control period and after 1518 min in Calcium-free external solution. 6 sham experiments were also conducted by keeping the slices in Calcium containing external solution all throughout and these showed no obvious change. The time course of decay of the IPSCs was slower in calcium-free external solution when compared to depolarization-induced calcium transients.Effects of elevated in tracellular CalciumElevated intracellular Calcium in the Purkinje cells caused a speedy frequency reduction and a slow increase in amplitude. This sudden fall could not be explained by the intracellular calcium as BAPTA buffered the Calcium in the cells and could not have caused the IPSCs.Effect of the axons in large amplitude miniature IPSCsThe immediate slow changes in the amplitude of IPSCs on withdrawal of external calcium for 3 minutes could not be attributed to the delayed removal of external calciumfrom pre-synaptic release sites. The arrange was also not due to local Calcium influx caused by the TTX insensitive axonal depolarization. For the latter test, external Cd,a non-selective channel blocker, was used. It reduced the action potential-evoked pre-synaptic Calcium transients seen in the axons and pre-synaptic terminals of cerebellar interneurons. The slow changes in amplitude were therefore not connected to rundown oraltered post-synaptic receptors or delayed extracellul ar calcium removal. The only remaining explanation was that multivesicular release under the pre-synaptic calcium stores could have caused the changes in amplitude. The lack of recovery after external Calcium coming back could be due to the slow store refilling of intracellular Calciumwhen action potentials and subsequent calcium influx are blocked.Rise Time dynamicsThe multi-vesicular release also could not completely explain the slow changes in amplitude. Rise time of IPSCs as a function of amplitude was studied after extended external calcium removal. In 6 of the 8 cells tested, the rise time was heterogenous in nature where two subpopulations were concerned. Slower decay kinetics was also noted.A faster rise time was seen in the proximal dendrites and soma. Faster IPSCs were more sensitive to external calcium removal than slow ones and these IPSCs arose at somatic synapses. The origin being multivesicular, synchronisation time must have been in the range of submillisecond. Som e IPSCs had slower rise time and decays and were less sensitive to external calcium removal. These IPSCs could be arising from dendrites and could be having synchronisation of 1-4ms.Ryanodine receptorsThe two photon laser illumination was used to focus on the ryanodine receptors stained with a high-affinity Calcium-sensitive dye, Oregon Green BAPTA-1. Transient rises of Calcium in the stained ryanodine receptors in response to short trains of action potentials were measured. The fluorescence rises were noted.Ryanodine-sensitive Calcium stores are associated with the large amplitude mIPSCs. In the experiment Ryanodine in large concentrations of 100 M blocked the receptors. The response recorded showed that Ryanodine reduced the mean amplitude and frequency of mIPSCs simultaneously. The responses to muscimol were not affected by ryanodine and the researchers assumed that ryanodine had no post synaptic effect.Axonal descry with calcium stores were identified in pre-synaptic terminals by recording responses to short action potentials. The intracellular Calcium fluctuations in response to differing concentrations of external calcium to which small concentrations of ryanodine were added was checked. Repeated scanning in the presence of TTX was done. Spontaneous calcium transients were noted before and after addition of ryanodine. Bright spots of fluorescence were noted at the pre-synaptic terminals. This signified the presence and increase of Calcium at the pre-synaptic terminals.Experiments were then done with small concentrations of Ryanodine 10 M. Large amplitude mIPSCs were recorded. High frequency bursts and amplitudes of the responses were greatly increased. The bursts could reflect the response at multivesicular and monovesicular sites. The histogram comparing the amplitudes in the control and after ryanodine was added showed a significant difference. The spontaneous Calcium transients occur at basket cell axons and their frequency was increased by small con centrations of ryanodine.

Soon after the discoin truth, a British scientist, William Hyde Wol endureon, tried to design an electric motor using the fundamental theory of electromagnetism. However, his effort make no upshots and failed to create the motor 1.Michael Faraday who dumbfound talked to both initiators of the theory started his experiments and managed to produce the very depression electric motor. Since he is the only who published his works, he was credited for discovering the theory of induction in 1831 without acknowledging Wollaston 2. This law predicts how magnetic celestial sphere would related to electri c field which then could produce electromotive force ( potential drop), a phenomenon generally called Electromagnetic Induction 2. This law is applied as the basic fundamental theory for many applications such transformers, inductors, electric motors and in this project case, as a generator 2.However, most of the scientists rejected the Faradays theory since it was not represented mathematically 1. But only pack Clerk Maxwell accepted the theory and described the law as Faradays impartiality of Induction mathematically which then later generalized to be called the Faraday-Maxwell Equation1 13. This equivalence is one of the four so called Maxwells Equation throughout all of his theory astir(predicate) electromagnetism 1.Faradays Law of Induction surely needs the magnetic liquidise through a loop of wire 4. The definition of magnetic flux is given bywhere B is the magnetic field and dA is surface entire enclosed by the loop of wires.In term of graphical definition, magnetic flu x through the loop of wire is directly symmetryal to the number of magnetic flux lines been cut when the magnet pass through the loop of wire 4.2.1.2 Lenzs LawThe Faradays Law of Induction also states that when the magnetic flux that pass through the loop of wire swapd, the loop of wire gained an EMF. Generally, this statement means that the induced EMF in closed circuit is defined as rate of change of magnetic flux made from the circuit 56. The definition in term of equation is as belowwhere is the EMF while is the magnetic fluxThe Faradays Law of Induction is then further modified and improved by physicist named Heinrich Lenz. The improvised law is called as Lenzs Law. This law, of which gives the vigilance of the EMF, states that the direction of the induced current is opposite of the direction of the change that produced it because of the negative sign shown in the equation above 7. In order to increase the induced EMF, it is known to customize the flux linkage since EMF is also known as rate of change of flux. This gutter be done by wounding coil of wires tightly producing N pass ons of wires, which from each one of the turn have the identical magnetic flux. The EMF produced through this method is N times of one single turn of wire 8 9. get into 1 Faradays Law of Induction producing EMFThe theory from the Faradays Law of Induction due to magnetic flux linkage been cut by loop of wire then get the fundamental principle in making electrical generators. This could be happened when a conductor or loops of wires is moved relative to permanent magnet or vice versa producing EMF. If both ends of the opened-circuit wires is connected to any electrical devices, current go away be produced and electrical energy is produced. This electrical energy is gained from the motion of the magnet which then proves the diversity of mechanical energy to electrical energy.2.1.3 PiezoelectricityPiezoelectricity is the ion charges which are collected in abundant amount in some solid materials, such as ceramics and crystal, and biological matter, for example DNA and bones 10. This could only be happened when mechanical stress is applied onto the particular substances. It is understood that piezoelectric performance was a result of linear electromechanical contact between electrical and mechanical state in materials whose structure are in highly microscopic structure order. These materials used for piezoelectricity are usually have no inversion symmetry 11.During the early mid of 18th century, the early discovery and research was studied by Carl Linnaeus and Franz Aepinus. However, the study was on pyroelectric effect. This pyroelectric shows that an electrical potential of a substances or material are produced whenever there is temperature changes 12. From this discovery, Rene Just Hauy and Antoine Cesar Becquerel conclude a family relationship between electric charge of a substances or materials with mechanical stress applied onto it. Despite of their experimental efforts to prove the relationship, they are likely fail to prove the experiments conclusive 12.Unable to full understand the principle, in 1880, The Curie brothers, Pierre Curie and Jacques Curie manage to demonstrate the very first direct piezoelectric effect 13. The brothers manage to predict the behaviour of crystal by combining their knowledge on pyroeletricity with their understanding about the crystal structure. The effect was demonstrated by the brothers using tourmaline (crystalline boron silicate mineral), topaz (silicate mineral of aluminium and fluorine), cane sugar and Rochelle salt (sodium potassium tartrate tetrahydrate) Quartz (mineral composed of silicon and oxygen) 13.However, the converse piezoelectric effect wasnt predicted by the brothers. Only in the next year, 1881, Gabriel Lippmann managed to deduce the converse effect from the basic principles of thermodynamics mathematically 13. Only then, the Curie brothers got to obtain the verificat ion of the changeability of the deformations in the piezoelectric crystals and thus proved the presence of the converse effect 13.The very first application of piezoelectric devices was as in sonar. It was first developed by Paul Langevin and his assistants during World War 1 at France which was about 1917 13. Starting from this creation where piezoelectric effect was used in sonar, the development of its technology and applications was intensely explored and developed. The most common application was found to be the piezoelectric demodulator.Piezoelectric sensor, as known from its name, of course uses piezoelectric. This sensor detects any changes in pressure, force, temperature, stress or strain in form of electrical charge. This is one of the reason why it is called electromechanical devices as it generally converts mechanical energy to electrical energyFigure 2 Electronic and schematic symbol of a piezoelectric sensorThe electrical properties of the sensor are that it has very high DC output impedance. This makes the sensor could also be sculpted as proportional voltage offset or network filter 14. Voltage across the source is directly proportional to any force, stress, strain or pressure applied onto it. The current passed through the circuit then go away shows as output signal of the sensor of which specifically shows the result of the mechanical force applied 14.Figure 3 Frequency response of piezoelectric sensorIf it is intensely considered, the effects of the mechanical construction and other ingenuity of the sensor are included in the specified model. To make it function as sensor, the straight region (usable region) of the frequency response will normally be used 14. As an effort to ensure that the low frequencies of interest (straight region) not lost, the leakage and load resistance must be sufficiently large. In this region, a corresponding circuit which has been abbreviated can be used. From the circuit, the capacitance of the sensor is signi fied by CS of which is defined by the general conventionalism for capacitance of parallel plates 14. However, the device can also be showed as charge source. This could only be happened if CS is in parallel yet the charge is still directly proportional to applied force 14.Figure 4 Piezoelectric sensor as voltage source or charge sourceThe principle operation of a piezoelectric material can be divided into 3 main operative modesLongitudinal effectThe total charge displaced does not depend on the dimension and shape of the piezoelectric elements. Yet, the amount charge displaced is directly proportional to the force or pressure. The one and only technique to surge the output charge is by placing a few piezoelectric elements in parallel as from electrical horizon but in series as from mechanical perpective. The output charge is as belowwhere is the piezoelectric coefficient as a charge in x-axis are being discharged by the forces exerted onto the same x-axis. , is the force exert ed in the x-axis while is representing the number of elements that been fixed together.Shear effectThe charges formed does not depend on the dimension and size of the piezoelectric elements at all and yet it is totally and directly proportional to the force and pressure exerted. The charge for elements which is placed in parallel as from electrical perspective but in series as from mechanical perspective can be illuminated as belowTransverse effectCharges along x-axis are displaced perpendicularly to a force that been applied along a neutral y-axis. The geometrical proportions of certain piezoelectric component determined the amount of charge displaced, CX.where is the proportion coordinated with the neutral axis, is coordinated with the charge producing axis while is the equivalent coefficient2.2 Theory of Lithium ion BatteryAmongst rechargeable battery that ever exist, lithium ion battery is known to be amongst the battery with highest capability to store energy per unit volu me. This is one of the reason why lithium ion battery is considered to be useful for electrical energy storage 15. Besides, lithium ion battery is also known for its capability and efficiency in charging and discharging 15.However, there is also disadvantages of using this lithium ion battery. Comparing to condensers and other different kind of batteries, it is essential for this lithium based battery to be charged using a definite voltage and restricted current 15. If the condition is not fulfilled, the useful used-to-store-energy battery could be one of the dangerous battery as it could potentially be fire-starting bomb 15.2.2.1 Principles of Charging and Discharging Stage of Lithium ion batteryThe very foremost thing that need to be understood about discharging and charging a battery is its C-rate which is the foundation of battery usage. Generally, the batteries are characterised with nominal capacity which is measured in ampere-hour (Ah). But most of the time, the batteries ar e labelled in milliampere-hour (mAh) 15. The label actually explains the amount of current supplied within one hour during the discharging state of the battery in front the battery are fully depleted 15.As an example, a battery labelled with 10000mAh which talent be also labelled as 10Ah, could only release 10A to a circuit. If the battery is being discharged through the circuit with 10A but last for 1 hour, it verbalize that the battery would have 1C discharge rate. It is also said to be discharged at rated capacity current. However, the discharge rate would only be 0.5C when the battery only provides 5A or 5000mA to a circuit. However, with 0.5C discharge rate, the battery would last for two hours 15. Some batteries do tolerate for higher discharging rate compared to 1C, but it couldnt last longer than 1C discharge rate.As for charging condition, the theory is generally the same. At 0.5 charging rate, the same battery that labelled 10000mAh would be charged with maximum curren t of 50000mA 15. However, comparing to discharge rate of a battery, most of the batteries are only charged at 0.5 to 0.7C charging rate because of safety and to have long- vitality battery 15.Graph 1 Lithium ion battery cycle life, capacity and float voltage are interrelateFrom the graph above, it is concluded that each cell of most of the lithium ion batteries are only charged to 4.2V maximum. This is because charging using higher voltages mogul reduce the battery life even though the capacity of the battery are improved 16. On the other hand, charging the battery using a lower voltage might increase the charge cycles but the run time of the battery are reduced 16.Many batteries can be classified as over-discharged when the cell voltage of the battery is below 2.8V or 3V. When this happened, the battery can still actually be recharged and used 16. However, a peak called aconditioning stage need to be done before the battery is charged again. Within the stage, the battery is onl y charged with 0.1C charging rate 16Graph 2 The constant current, constant voltage charge profile of lithium ion batteryThe charge cycle of lithium ion battery is illustrated by the graph above. Generally, every charge cycle of single lithium battery contains two main stages which is Constant Current (CC) and Constant Voltage (CV). However, some chargers which charge series of lithium ion battery have an extra stage that is called equilibrize Stage 16. business relationship for each stage 16 is explained as belowConstant Current (CC) This stage is always used by all the chargers and it is the one and only stage aimed at the fastest chargers. Generally, the battery is connected to current-limited power supply during this early stage. The limited current is normally 0.5 to 0.7 of the nominal capacity of the battery. The limited current flows continuously and endlessly until the voltage of the battery cell inducees 4.2V. At this very moment, the charge of battery is expected to be around 70 to 80% 16.Constant Voltage (CV)This stage is also known as the saturation stage. In this stage, the charger turns its role into voltage-limited power supply. Contradictly from the previous stage where voltage of the battery continues to be unchanged, the charge current decrease steadily. The battery is only acknowledged to be fully charged when the charge current is encouraged to be 3 to 10% of the rated capacity 16.Balancing StageAs told before, this stage is normally only when series of lithium ion batteries need to be charged. In this stage, the charging current is normally lowered or in some cases, the charger is automatically and rapidly turned on and off in order to decrease the average current. At the same time, the charge of each battery cell is kept to the equal level. This was done by a circuit called balancing circuit. The stage will stop only when the batteries are found to be balanced.2.2.2 Environmental TemperatureGenerally, lithium-ion battery give best cha rging performances only at cool temperature. The temperature accepted for the best performances ranging from 5 C to 45 C. Sometimes, the battery might even offer fast-charging within the accepted temperature 15.It is also possible to charge the battery at low temperatures (below 5 C). However, the cost to charge at low temperature is that the charge current will be reduced and indirectly, it would take long times for the battery to be fully charged. When the battery is charging in the low temperature, any increment in the temperature which is caused by the internal resistance of the cell would highly be beneficial even though it only small increment.On the other hand, charging the lithium ion battery in high temperatures can cause the battery to be degraded. Besides, charging the battery at high temperature (above 45 C) also might mite to degradation of the battery performances.3.1 IntroductionIn order to simplify the design and build the system, the project was split into modules. The project modules were initially designed to be like in the block diagram below.Figure 5 Initial flow chart of the motion-powered portable chargerThe modules were later adjusted based on the knowledge gained from the literature go off. The adjusted modules are shown as below.Figure 6 Final flow chart of the motion-powered portable chargerFrom the flow chart above, it can be seen that the input of the system is made to have two inputs. As for the system, the main input supposed to be the Kinetic/Mechanical to Electrical Energy Converter. However, the other input which is the AC Power Supply is also considered because it is made to be the alternative input just in case if there is any system failure in the main input.From the flow chart, there are three modules that are available in the market and would be useful for the system. The modules are AC Power Supply, Lithium ion Battery and 5V Voltage Regulator.3.2 Kinetic/Mechanical to Electrical Energy ConverterIn this module, the de sign choice to generate the electricity which are harvested from kinetic or mechanical energy have been made. The design choice that have been made uses Faradays Law of Induction and Lenzs Law. Faradays Law of Induction applies that an electromotive force (EMF) will be produced when there is change in magnetic flux when a permanent magnet is passed through a loop of wire. Furthermore, Lenzs Law explained that the electromotive force (EMF) produced have different directions depending on the direction of the movement of the magnet relative to the loop of wire. Lenzs Law also indicates that the EMF can be converted into electricity if both ends of wire are connected to electrical load and it would produce an alternating current.Figure 7 Shake Generator with permanent magnet sure in the tubeFrom the understanding of the laws, a shake generator is made as in the figure above. The shake generator is made by using 30SWG magnet wire circling around a Perspex tube. A permanent and powerful magnet is then placed in the tube. Both end of the Perspex tube is then sealed using rubber-closed blind.Knowing that the generator would produce alternating current and produce low voltage, a circuit is designed which combined both AC-DC Converter and 12V getup voltage regulator. The AC-DC converter only consists of four 1N4001G diode which combined to form rectifier. On the other hand, the voltage regulator is created by using the LM7812CT Fairchild Semiconductor, 0.1 F capacitor and 10 F capacitor.Figure 8 AC-DC Converter and 12V 2A Voltage Regulator Circuit3.3 Battery Charging CircuitFigure 9 Battery Charging CircuitIn this circuit, a LM324N Operational Amplifier (op-amp) is used. The op-amp is used to produce a voltage and current limited power supply as in reviewed in the literature review early in this report. In this circuit, the current can be adjusted by using a potentiometer to produce current ranging from 160A to 1600mA. This allows the charger to charge discordant cap acity of lithium ion batteries. The op-amp is used so that the voltage is limited to 4.2V. Thus, the lithium ion batteries will not be damaged.Besides, the circuit also used the TIP122G junction transistors. This transistor generally is a Darlington bipolar power transistor. This transistor can actually be replaced with any transistor which have pin that compatible with TIP122Gs pin. The transistor also need to have minimum DC current gain more than 100. Besides, the maximum collector current also need to be more than 2A.3.3.1 Power Supply of the ChargerFigure 10 Power Supply Circuit of the Battery ChargerThe battery charging circuit is mainly power-driven by a charger with rating of 12V 2A as designed in the Kinetic/Mechanical to Electrical Energy Converter module. It is found that the op-amp LM324N is not a trail to rail type. Thus, another voltage rail is needed so that the op-amp could detect the small voltages near the state (GND). Besides, it is also made the output voltage to be low so that the Darlington transistor (TIP122G) wouldnt turned on when they are not supposed to.By referring to the overall schematic circuit of the Battery Charging Circuit, it can be seen that the transistor, that adjust the flow of the current and voltage across the lithium ion battery (illustrated by the oscilloscope), is not connected to ground but to a voltage rail. This is because the output of the LM324N op-amp couldnt reach the negative voltage supply. It can only reach 1.5 to 2.0V. At this condition, the TIP122G Darlington transistor couldnt be able to turn off and would result in the transistor for not be able to limit the current and voltage appropriately.This is one of the reasons why op-amp U1A and a transistor are used. This is to create a 2.5V rail practically compared to ground (GND). The voltage rail created are further used to sink the current which pass through the charger section of this module.From the circuit, the function of the resistor R2 and R3 are to act as potential divider which gives an average output voltage of 2.5V. However, it is still depending on the tolerance of both resistors. No matter on how the current flow, 2.5V will always loss across the op-amp which controls the transistor.In the circuit, the LED shows whether the charger is on or off. In addition, C2 steadily adjust the voltage out from the charger. In the battery charging circuit module, all of the op-amps and the charging indicator (illustrated by the LED) are precisely powered from the 12V supply. However, the remaining of the circuit is powered with the voltage between 12V and 2.5V rails which is 9.5V.3.3.2 The charger circuitFigure 11 Actual Charger CircuitThis section is the most significant section of the charger because this is the section that responsible in restricting the voltage and current across the lithium ion battery. From the circuit, the limited current can be controlled from the 10k potentiometer. However, the limited voltage will be cons tantly at 4.2 V unrelatedly to the various kind of the power supply.The potentiometer also effectively works together with the U1C in limiting the current of the battery. The current passing it and the voltage across might be equal since the determine of the sense resistor is only 1 .The potentiometer is above the 1k resistor and the voltage across the 1k resistor is 160mV. This would make the low voltage of the output of the potentiometer would be 0.16V. In this condition, this circuit would produce limited current of 160mA which is a suitable condition to charge a lithium ion battery labelled with 300mAh.The highest limited current through the potentiometer can be somewhat more than 1.6A since the voltage drop that been found across it is about 1.6V. Thus, by changing the potentiometer, the possible output voltage obtained can be around 0.16V to 1.6V. On the other hand, this also means that the highest limited current can be ranging around 1600mA to 160A.The transistor will be driven by the op-amp to make the voltage across the sense resistor to have the equal value as in the output of the potentiometer. Besides, the op-amp might get to produce low voltage that is just sufficient to make the transistor turn off and to induce a low limited current all because of the 2.5V rail.Towards the finale phase of the constant current stage, the voltage of the lithium ion battery become closer to the value of 4.2V. At this situation, the limiting voltage stage of the circuit and the constant voltage stage will start to take over the process.A 4.2V situation under 12V (VCC) are created by the BZX79 4.7V Zener diode and the potential divider that consists of R10 and R11. At the moment where the voltage across the lithium ion battery get to 4.2V markings, the U1D op-amp begins to drive voltage into the reversing input of the other op-amp. This process will allow the op-amp to reduce the voltage of the output to the transistor. Thus, the current passing through the lith ium ion battery will begin to overtake steadily in order to maintain 4.2V across the battery.When the l
