Humanity Case Essay Example for Free

Humanity Case EssayHumanity. Perhaps this is the only word that can explain the eerie comings and goings of the man from Naz areth, c totallyed messiah. The Lost Tomb of rescuer, aired March 3, on the Discovery Channel, an amazing piece of documentary. In the city of Jerusalem, in the midst of an apartment complex, was erect a place of burial. Perhaps the burial place of, Mary Magdalene, her son Judah, and two brothers-in-law, Simon and James. Were these the relatives of Jesus the Christ, in the scheme of things the question seems to be irrelevant. Humanity Although in that respect is great emphasis placed on the Christ, the Messiah. Very few people seem interested at all in Jesus humankind. People are offended at the thought that Jesus may have deigned to have been with a woman, much less married to a whore. Yet this is the very explanation told in Hosea. divinity fudges un inquisitive love of even, maybe most especially, one who would be unfaithful. It seems to me of al l of Jesus disciples, Mary is the one who got it. Only an outcast could truly apprehend the message of Christ. To be offered kindness, when only suffering has get at the hands of man, is an indescribable miracle. How Mary must have loved this man, Jesus. The Divine, the Christ. Jesus humanity is controversial. And I dont know why. If Jesus was not fully human, how could God come to know what it is to be human? To struggle? To be defeated? To know unbridled gratification? To be shortsighted as man is and yet still have the ability to hope. How God must love us for that Yes, all have sinned and come short of the Glory of God. Who among us is not aware of their own shortcomings? Everyone I know. To be human is to be all to aware of what we are not. Was that the purpose of Jesus coming? To remind each of us of our all too familiar failures? Many others are outraged that anyone should question the Divinity of Christ, as though questioning such a thing changes the very nature of God? Hardly. What question could man possibly ask that could be found to be offensive to God? Yet, this question of Divinity versus Humanity, people seem to struggle over. Christ is all or none. Even those who would say Jesus was both human and God, cannot admit that Jesus could have succumbed in his humanity to be human. And what a terrible misrepresentation. All throughout the Bible God is represented as part of humankind. Why would humanity be denied what most Christians believe to be Gods only Son. There is of course, great misrepresentation and misunderstanding about the chronology of the canon. That Jesus divinity was not even say until 300 years after his death. By whom? Why man of course? I wonder if God would be pleased with all that the church, not the body, has elegant? Just recently, I visited a new church and although I liked the people. I was saddened when the pastor started talking about the building fund. Is this what Christianity has been reduced to? Buildings? What of the starving? What of the homeless? What of the person who has not known the kindness of a human touch, due to illness or simple isolation? What of these? Does God not plague us to be in touch with his light, his life, his children? The Lost Tomb of Jesus is a wonderful representation of the possibility that Jesus was all he said he was. A miracle. A blessing in disguise. Both human and Divine. Just like the rest of us. A bit of God rests in us all at the heart of Gods highest creation, mankind. Rejoice Awake God is among us Living when we thought he was dead Alleluia Jesus is Alive

Conveyor Bases Sorting System Colour Sensor Signal

Conveyor Bases Sorting System Colour Sensor SignalCONVEYOR BASED SORTING SYSTEMCOLOUR SENSOR call for CONDITIONINGAbstractThis report analyses the best strategy for interfacing the falsify detector with the microprocessor by using either Comparators or Analogue to Digital Convertors (ADC) in the process. management mainly on the advantages and disadvantages of these cardinal components, we can conclude which one is more effective and responsive with cost, time taken to process the programme and reliability. Using C programming a microprocessor is programmed in order to detect the colour of the objects passed on the conveyor belt using LDR.Analogue to Digital Convertor (ADC)It is a establishment that converts the input analogue augurys (from a light source or sound signal) to digital takings signal by a process called quantization, which is also called as digital signal processing that is the process of mapping a large set of input values to a countable smaller set. Generally, the digital turnout signal is in binary number that is proportional to the input values.Component parts of ADCThere are seven different components within the ADC that make up the whole processing duty tour which includes,Set-Reset latch has 2 inputs and outputs which used as storage element in ADCClock a constant input signal that fluctuates between high and low and is used coordinate the actions of the tour of duty.AND gate a basic logic gate which has only high inputs (1) to start the conversion when prompted. replication an electronic device which stores the number of times something occurred and used directly with the clock signal.DAC to convert the digital signals to analogue output signals when commanded (reverse function of an ADC)DATA latch takes the output of counter as its input and convert the analogue signals into digital outputs.Comparator that compares two voltages or currents and changes its output depending on which is larger.Advantages of ADCSome benefits of using the ADC in this colour sensor interfacing system with the microprocessor are listed below,Cheap in cost and speed varies to different ADC for example flash ADC is the fastest of all its kind.ADC has higher re source than using a comparator.Less steps and components when it comes to programming in a microprocessorClock in ADC keeps the circuit in time and provides a square wave input.Set-reset function allows the circuit to be functioned and keeps it in control.It converts any input voltages, even from 1V to 5V into a digital output (flashing LED from less bright to precise bright display) through its construct in components whereas in a comparator it is either 0 from 0V to 2V and 1 from 2.5V to 5V.Disadvantages of ADCAlso the drawbacks of using the ADC are,Slow in speed compared to a comparator device as ADC has more component parts than comparator.Each and e really parts have to be earthed appropriately.Have to have many inputs into the encoder (for 4 bit outputs 16 in put signals and for 5 bit its double the inputs).ADC has several sources of errors like quantization error. These are measured in least significant bit (LSB)ComparatorComparator is an electronic device that compares the input two voltages or currents and outputs the higher or larger (1) digital signal. It consists of a specialized high -gain differential amplifier which are commonly used in devices that measure and modify analogue signals, such as Analogue to Digital Convertors (ADC). Comparators are also being installed within analogue to digital convertors (ADC).Advantages of comparatorUsing the comparators in the microprocessors in the circuit can have some positive impact on the project. Some of them are,Cheaper in cost when comparing to other devices of amplifying.Comparators does not require an external originator source such as additional current or voltage supply since the power comes from the processor.These are in ordinary working condition and very compact and robust mo del and are very easy to handle. Can be portable as well.Electrical comparators have very less mournful parts and the pointer is very light and not sensitive to the vibrations.Disadvantages of comparatorSome of the disadvantages of using the comparators are,Heating of coils in the measuring unit may cause set drift and can alter the calibration.If only a fixed scale is used with a moving pointer then with high magnifications a very small range is obtained, in this case itll be from 0V to 2V its low (0) and from 2V to 5V its high (1).ConclusionUsing an Analogue to Digital Convertor would be the possible solution in this colour sensor operating system as there are more benefits from ADC than Comparator. Since ADC has higher resolution and uses two registers to record the values from their 10 bits of inputs, it is more reliable and accurate with a few quantization and bubble errors. Comparator is one of the parts in ADC and it can only be used to compare two or less objects as it ha s a maximum of two outputs but ADC has plenty.Therefore, with ADC we can identify the three different coloured objects through this colour sensor.

Cognitive Behavioural Therapy for Psychosis

Cognitive Behavioural Therapy for PsychosisA literature review in chronological order from past 5 yearsIntroductionThe blanket term Psychotherapy covers a multifaceted pluralistic enterprise in which a mold of therapies is required to meet a patients various needs (Holmes J 2002). The National Service Framework cites cognitive demeanour therapy as organism the psychotherapeutic method of choice for conditions that include depression, eating disorders, panic disorder, obsessive-compulsive disorder, and deliberate self harm. (Rouse et al. 2001)Literature reviewThe first article we shall consider is a letter to the editor of the BMJ by Van Meer (R 2003). It is comparatively unusual since it is a clinician referring to clinical matters which are both intuitive and experience based. The author refers to the event that numerous psychiatrists and related healthcare professionals real avoid talking about the content of psycho symptoms. The generally accepted lucide being that these a re diagnostically of no significance and therefore therapeutically irrelevant. Van Meer contrasts this view with the basic concepts of cognitive demeanour therapy. He suggests that in his experience, the patient actually often will want to talk about issues that are central to their experience and are distressed when they are kept out of the conversation. He suggests that this is one of the reasons why cognitive demeanour therapy is familiar with psychotic patients is that they stool the opportunity to discuss with sympathetic professionals the significance of their experiences and this is capable of giving them a mechanism of dealing with what may be otherwise unaccountable to them. This publication is selected because of its counterintuitive thrust to support cognitive behaviour therapy against the mainstream of current clinical psychiatric practice and is written by an experienced practising clinician. This area of friendship is given a further twist with a different insig ht from Moorhead (S 2003). He agrees that psychiatric professionals tend to try to avoid engagement with psychotic patients on the subject of their psychosis and thereby unwittingly add to the prejudice that blights the lives of people who live with psychosis . He points, very succinctly, to the fact (and cites Brabban A et al. 2000) that the central tenet of cognitive behaviour therapy is that the therapist should endeavour to show a clear linkage between personal experience, core beliefs (schemas), and emergence of psychotic symptoms. The significance of this publication is that it is unusual hitherto as it outlines the benefit of cognitive behaviour therapy for the staff as much as the benefit for the patient, by suggesting that staff trained in the techniques of cognitive behaviour therapy are able to empathise on a much deeper level with the patient and this, in itself, has a remarkable remoralising effect of developing a purposeful understanding of the psychotic phenomenon w ith a patient. This point is echoed in the discussion of the Craig piece of music.The Craig paper (Craig T K J et al. 2004) is a carefully constructed, but ill reported, randomised controlled trail of the current efficacy of specialised care modalities for movements of early psychosis. (Vickers, A. J et al. 2001). It is presented here as a case study in lively analysis. The discussions were delivered in two groups. The entry cohort was allocated to a standard care group (the control) or the intervention group (specialised care group). Both sets of treatment were delivered by the community mental health teams. The outcomes for both groups were rates of relapse or readmission to hospital. (Friedman GD. 1994)We present this paper to illustrate a common problem with this type of campaign. On first appreciation, it demonstrates the fact that the intervention group did better than the control group. The difficulty in critical analysis comes in trying to decide which of the treatment modalities actually produced this beneficial effect. (Mohammed, D et al. 2003)The entry cohort was quite impressive for a study of this type with 319 presenting with psychotic illness over an 18 month stop and 144 of these meeting the inclusion criteria. 94% of these were remained in the trial over the 18 months of follow up.We note that, although the programme of interventions did include cognitive behaviour therapy, it withal included other treatment options such as low dose atypical antipsychotic regimens, cognitive behaviour therapy based on manualised protocols, and family counselling and vocational strategies based on established protocols (Jackson H et al. 1998). From the point of view of our considerations here, on the one hand the results appeared to be good insofar as the study showed that the intervention group had fewer readmissions to hospital in the study period and as well they had fewer psychotic relapses (although this was of low statistical significance). On the other hand the paper tells us that all patients had medication and the ultimate choice of treatment pathway was decided by the intervention clinician, so although cognitive behaviour therapy was used, we have no absolute idea of its effectiveness from this trial. (Green J et al. 1998). All we can say with confidence is that, as part of a total package, cognitive behaviour therapy appeared to have helped to contribute to a beneficial outcome for a significant number of psychotic patients. A completely analytical and minimalist approach to this peculiar(prenominal) trial could suggest that it is indeed possible that cognitive behaviour therapy is actually ineffective per se. other than it served to keep the patient in closer contact with the clinicians. (Piantadosi S. 1997)In this prise this is an instance of a trial which is seemingly supportive but does not contribute greatly to the evidence baseOn first sight this particular view might be considered pedantic, but it is echoed by Yates (DH 2005) in a letter in the BMJ, where he specifically takes up this very point. He points to the fact that there is very little description of the regimes of cognitive behaviour therapy and the degree that its impact can be isolated from the overall effect. He besides refers to the fact that a breakdown of the various therapies offered and the degree that each was helpful would have improved the paper tremendously. We have to agree.We will next consider a high profile paper by Morrison (A P et al. 2004) which has been widely cited. This paper took the pioneering work of Yung (et al. 1996) who identified a high risk group of patients who would develop psychosis and examine the effect of cognitive behaviour therapy on the prevention of the development of the clinical state. Morrison et al. identified the fact that other studies (McGorry, P. D et al. 2002) had demonstrated that it was possible to reduce the incidence of psychosis development with a multifaceted approach, lik e that of Craig, which included elements of cognitive behaviour therapy. Morrison however, elected to carry out a study that used cognitive behaviour therapy as a single strand approach in this high risk population. (Leaverton P E. 1995)The results from this study convincingly demonstrated that cognitive behaviour therapy completely significantly reduced the likelihood of making progression to psychosis as defined on the Positive and Negative Syndrome Scale over 12 months. (Kay, S. R et al. 1987) The authors were also able to demonstrate that cognitive behaviour therapy also reduced the likelihood of a patient being prescribes antipsychotic medication. Other criteria of analysis demonstrated that cognitive behaviour therapy significantly improved the positive symptoms of psychosis in the target population.This is an important study as it is one of the first to provide a reasonably undecomposed evidence base that cognitive behaviour therapy works in the psychotic patient. It also shows that it works in the high risk group and has the possibility of a prophylactic effect by minimising the likelihood of psychotic relapse.A critical analysis would observe that the intervention cohort was comparatively small and a disproportionately small number were entered in the control group (37 and 23 respectively). High risk psychotic patients are comparatively rare and therefore one has to care for the practical difficulties involved in accumulating a sufficiently large sample to study. (Grimes D A et al. 2002),The last publication that we shall consider is that by Trower (P et al. 2004). It was published at the same time as the Morrison paper and is notable for the fact that, like the Morrison paper it recognises the shortfalls of the previous multi-modality studies and isolates cognitive behaviour therapy in its analysis. It also specifically targets a notoriously treatment-resistant group of psychotics, those who suffer from command hallucinations. (Haddock, G et al. 1999)This was a single blind randomised trial with 38 patients. The trial was complex in social structure but, in essence, it was able to show, with convincing statistical significance that cognitive behaviour therapy interventions alone was able to reduce the patients compliance rate with the psychotic commands. The authors noted that this reduction in compliance was associated with a reduction in levels of both anxiety and depression.In conclusion we would like to commend the book by Eisenman (R 2004) The Case Study Guide to Cognitive Behaviour Therapy of Psychosis as a particularly authoritative and clinically useful overview. It cites a number of clinical case studies and analyses them in depth. It supports the view that cognitive behaviour therapy, by attempting to confront the patients distorted thinking and allowing them to appreciate their thoughts in a more rational and realistic way, can have beneficial results and it places cognitive behaviour therapy in a clinical conte xt amongst the other, generally accepted modes of psychotherapy. It is not a couple reviewed publication so we shall not consider it further than that.ReferencesBrabban A, Turkington D. 2000The search for meaning detecting congruence between life-events, underlying schema and psychotic symptoms.

Essential Trace Metals in Seaweed

Essential Trace Metals in Seaweed0 IntroductionSeaweeds argon marine macro-algae that are one of the donjon renewable resources of the marine environment and well known for its potential food and therapeutic applications (Tseng, 2004). correspond to Awang et al. (2008), Sabah and Sarawak have a great potential for the cultivation of seaweed. The seaweeds constitute in Sabah such as Kappaphycus alvarezii, Ulva reticulate, Gracilaria changgi, Caulerpa lentillifera and Sargassum polycystum species.Seaweeds are one of the best sources of demand wind metallic elements. Essential sign metals are metals needed by tender-hearted body in little quantity. These metals brush aside be determined by development atomic spectroscopy techniques. Consumption of seaweeds digest increase the center of dietary fiber and lower the development of some chronic illnesses (S come outhgate, 1990). The followings are some inseparable singularity metals lay out in seaweeds and their benefits to hu man (Alexander, 2014)However, some questioners describe that some seaweed are contaminated and contained high amount of substantive decode metals more than the amount needed to human body. These are due to the area and conditions of seawater. According to Noda (1993) the chemical composition of seaweed whitethorn vary due to the species, geographic area, seasons of the year and temperature of water.This topic focused on the congenital trace metals found in contrasting type of seaweeds. The terminations of the concentration of the essential trace metals are compa bolshy to dietary reference intakes (DRI). This study is significant to show the role of essential trace metals and enhance the consciousness on the importance of essential trace metals to human health.Problem StatementSeaweeds can be classified into iii main groups which are Phaeophycae, Rhodophyceae and Chlorophyceae. The compositions of essential trace metals in these groups are differed. Some groups contain hig h amount of certain essential trace metals and vice versa. These essential trace metals are classical for maintaining health. These metals take part in enzymes, hormones and cells in the human body. Inadequate intake of essential trace metals can cause symptoms of nutritional deficiency. There are some(prenominal) queryes that have been done on seaweeds. Most of them discussed more on the composition of macronutrients in seaweeds. Therefore, this research focused on essential trace metals. There is prerequisite to know the composition of essential trace metals in these seaweeds because they supply nutrition and give benefit to humans health.3.0 Objectives of studyTo determine the concentration of essential trace metals like vanadium, zinc, iron, copper, atomic number 25, chromium and moment in seaweed by using inductively coupled germ plasm voltaic pile spectrometry (ICP-MS).To compare the concentration of essential trace metals found in seaweed with the dietary reference int akes (DRI).To compare the concentration of essential trace metals in different types of seaweeds and determine which seaweed has the highest value of essential trace metals.4.0 belles-lettres Review4.1 IntroductionMany researches have been made to determine the composition of seaweeds. In the previous researches, they discussed more on the composition of macronutrients in seaweeds and lack of micronutrients. This research focused on essential trace metals found in seaweeds. This research is significant as these metals provide and supply nutrition values to human. This research is carried out in order to determine the concentration of essential trace metals like vanadium, zinc, iron, copper, atomic number 25, chromium and molybdenum in seaweed, compare the concentration of essential trace metals found in seaweed with the dietary reference intakes (DRI), compare the concentration of essential trace metals in different types of seaweeds and determine which seaweed has the highest valu e of essential trace metals.4.2 Definition of essential trace metalsEssential trace metals are metals that are required for human body in small amounts generally less than hundred milligrams per day (Cesar, 2005 Araya et al., 2006). These trace elements are minerals which human body can non produce by itself but can be found in diet. Essential trace metals include vanadium, chromium, manganese, iron, cobalt, copper, zinc and molybdenum (Gadd, 1992).Figure 1 shows the position of essential trace metals in the periodic display board. These metals are transition metals and majority of them are located in period 4, demo the relationship between the size of nuclei and the availability of electron of the element to interact with organic molecules vex in biological systems (Cesar, 2005).Each essential trace metal has their own specific functions depend on their chemical structures and is important for life. Although these metals are needed for only 0.02% of the total body weight, they are vital as trace bioactive substances and active centers of enzymes (Osamu, 2004). A man required essential trace metals about 50 micrograms to 18 milligrams per day and these metals function as catalytic or morphologic components of larger molecules (Mertz, 1981).Essential trace metals do not exist by themselves but exist with each other. Excess of one trace metal can cause imbalances in other elements and lead to diseases. To be well-absorbed in the intestine, most trace metals need to be in ionic form. Diet, concentrations of trace element in water, interactions of drug-nutrient are crucial to stabilize the concentration of essential trace elements in the body (Alexander, 2014). Figure 1 Periodic Table with white background indicating elements essential for human and bold characters representing the essential trace metals and non-metals (Cesar, 2005).4.3 Recommended daily intake of essential trace metalsA certain daily intake of food supplements is needed by humans. The essent ial trace metals are important as enzymes, hormones and cells in the body. Inadequate intake and excessive consumption of essential trace metals can cause symptoms to human body. Table 2 summarizes recommended daily intakes of essential trace metals and its effects of excessive consumption.Table 2 Recommended dietary allowances of essential trace metals (Dietary Reference Intakes, 2001).4.4 Classification of seaweedSeaweeds can be classified into three main groups based on their brown, red and green pigmentations. The groups of seaweed are Phaeophycae, Rhodophyceae and Chlorophyceae respectively. Sargassum polycystum species is in Phaeophycae group whereas Kappaphycus alvarezii and Gracilaria changgi species are in Rhodophyceae group and Ulva reticulate and Caulerpa lentillifera species are in Chlorophyceae group (Awang et al., 2014).The sizes of seaweeds are different according to their group. Brown seaweeds are much large. They are usually having length about 20 meters long and t he thickness is about 2 to 4 meters, whereby the smaller species is about 30 to 60 centimeters. vehement seaweeds are usually smaller in size, generally ranging from a few centimeters to about one meter in length. The colors of red seaweeds are not always red. They might be purple, brownish red, but botanists classified them as Rhodophyceae because of other factors. Green seaweeds are small, with a similar size to the red seaweeds (Fisheries and Aquaculture Department, 29 October 2014).4.5 The study of essential trace metal in different type of seaweedsSeaweeds rich in about 8% to 40% of essential trace metals required for human body (Indegaard Ostgaard, 1991). Some reports said that the metal contents in seaweeds were higher than edible prop up plants (Ortega et al., 1993). Concentration of essential trace metals may differed with each other because of several factors includes genetic species, sea conditions, seasons, habitats, maturity, geographical locations and environmental parameters of the seaweed (Ito Hori 1989 Fleurence, 1999 Krishnaiah et al., 2008).According to past researches, the commonly essential trace metals found in seaweeds were copper, cobalt, iron, manganese and zinc. Copper plays an important role in metabolism by allowing enzymes to function properly (Harris, 2001). Copper is vital for maintaining the strength of the skin, blood vessel, epithelial and connective wind throughout the body. Cobalt is essential for the production of vitamin B12 that is necessary to ensure an adequate number of red blood cells are produced in the body (MedlinePlus 2014, 23 October 2014). coat is important for growth, cell division, immune system, vision and also helps to accelerate the renewal of the skin cells (Vallee Falchuk, 1993). Iron is essential as oxygen and electron transport forhemoglobin discount of erythrocytes, oxidationreduction reactions, and cellular proliferation (Yutaka et al., 2008). Manganese is important for the formation of bones, connective tissues, brain and nerve functions (Barbara, 2013).4.5.1 Kappaphycus alvarezii speciesThe trace amount of manganese, iron, zinc, cobalt, chromium and copper were determined in this species that was collected from Palk Bay Mandapam, Tamilnadu in South India region. The concentrations of these metals were 10.6 ppm, 438.7 ppm, 25.5 ppm, 3.9 ppm, 52 ppm and 31.9 ppm respectively (Nageswara, 2013). Another sample was taken from Semporna in Sabah, showed that zinc, iron and copper were present in this species. The concentrations of these three metals were below 3.5 g/100g (Mansoor et al., 2012). From the study, it can be concludes that sea conditions and environments affect the concentration of essential metals in seaweed. In other research, to determine the composition of seaweed by using different types of seedling production, the micropropagated Kappaphycus alvarezii yielded significantly higher concentration of cobalt, copper, manganese and zinc compared to farm-propagated Kappaphycus alvarezii (Suhaimi et al., 2014). Fayaz et al., (2005) stated that Kappaphycus alvarezii species is a good source of essential metals, containing 0.033% of iron and 0.016% of zinc. The molybdenum is also present in Kappaphycus alvarezii about 0.04 milligrams (Suresh, 2014) and about 1.56 ppm of cobalt found in this species (Rajasulochana et al., 2012).4.5.2 Ulva reticulate speciesUlva reticulata species from Pattani was describe to contain high level in manganese and iron and also small amount of zinc and copper. The concentration of manganese, iron, zinc and copper are 48.1 mg/100g, 174.8 mg/100g, 3.3 mg/100g and 600 g/100g respectively (Pattama Anong, 2006). Awang et al. (2008) reported the range amount of iron is 6.5 mg to 11 mg per 100g, 2 mg to 7 mg per 100g of zinc, less than 0.55 mg/100g of copper and less than 3 mg/100g of chromium present in this species.4.5.3 Gracilaria changgi speciesGracilaria changgi species was reported to contain high level of zinc, iro n, and copper with the concentration of 13.8 mg/100g, 95.6 mg/100g and 0.8 mg/100g respectively (Norziah Chio, 2000). The result showed that this species has high amount of iron when compared to other vegetables reported by Tee et al. (1988). The comparison of iron content in Gracilaria changgi species and other vegetables are shown in table 3.Table 3 Concentration of elements (mg/100 g wet weight) present in G. Changgi (Norziah Chio, 2000) and in some vegetables (Tee et al.,1988).From the study, it shows that seaweed is the best source of iron compared to other land vegetables due to its metabolic system which it can absorb elements directly from the seawater.4.5.4 Caulerpa lentillifera speciesIron, zinc and copper were present in Caulerpa lentillifera species which is taken from Semporna in Sabah with the concentration of 21.37 mg/100g, 3.51 mg/100g and 0.11 mg/100g respectively (Suhaila et al., 2009). Duduku et al. (2008) determined the amount of 6.45 mg/100g of iron, 3.53 mg/1 00g of zinc, and less than 1mg/100g of copper and chromium found in this species. The sample was also taken from Sabah. The study about the composition in Caulerpa lentillifera species showed that iron, manganese, copper and zinc were present with concentration of 9.3 mg/100g, 7.9 mg/100g, 2200 g/100g and 2.6 mg/100g respectively (Pattama Anong, 2006).4.5.5 Sargassum polycystum speciesA research has been made that used sample of Sargassum polycystum species from Seribu Island in Jakarta showed the concentration of 0.002 mg/g of copper, 0.004 mg/g of zinc, 0.277 of iron and 0.010 of chromium were present (Joko, 2006). In other research that used sample from Kota Kinabalu, the present of iron, zinc and copper were also reported in small amounts with the concentration of 68.2 mg/100g, 2.15 mg/100 g, and 0.03 mg/100g respectively whereas other essential trace metals were not determined (Suhaila et al., 2009).4.6 Methods used to analyze the essential trace metals in seaweedAtomic spectr oscopy techniques viz., flame atomic absorption spectroscopy (FAAS), graphite furnace atomic absorption spectroscopy (GFAAS), inductively coupled plasma optical emission spectroscopy (ICP-OES) and inductively coupled plasma mass spectrometry (ICP-MS) are widely used to analyze trace element. Nageswara (2013) used FAAS method to determine the trace element in seaweed, the instrument was calibrated with normal solutions and a hollow cathode lamp was used for detection of lead, cadmium, copper, nickel, iron, cobalt, chromium, manganese, zinc, platinum and palladium. In other research, Awang et al. (2008) used GFAAS method whereas Rodenas et al. (2009) used ICP-MS method and Suhaimi et al. (2014) and Suresh et al. (2014) used ICP-OES method.This research uses ICP-MS method. Inductively coupled plasma mass spectrometer is suitable for the determination of trace metals with pretreatment and laser ablation device. This method has high sample throughput and the sensitivity is extremely hi gh. It has lower detection limits and the ionisation is efficient. In order to get the concentration of essential trace metals in seaweed, the elements are placed in solution by acid digestion. This solution is because nebulized into spray chamber and then carried by argon gas into a torch. ICP is argon plasma and can reach temperatures of 10,000 Kelvin. This allows the atomization of the trace metals in seaweed to concluded and reduced the interferences of potential chemical (PerkinElmer, 23 October 2014). The positive ions in the plasma are focused down a quadrupole mass spectrometer. This quadrupole mass spectrometer speedily detects the mass range. By getting the mass spectrum of the plasma, information about the trace metals can be obtained.

Power in Congress Essay -- essays research papers

Power In and Over CongressI feel the system is biased because there are inequalities among the representation and federation of interest groups and constituents in the political system. Unfortunately, poor and uneducated citizens arent as organized as interest groups, lobbyists and PACs because they lack the money, resources and connections necessary to influence congress members on legislative bills. It is evident that, businesses, interest groups and labor unions are spending more than $100 million a month to lobby the federal government(Associated Press, SFC, 3/7/98). The actual population of interest groups in Washington surely reflects that there is a class bias in the membership of interest groups(JBG). rice beer groups are organized bodies of individuals who share some political goals and try to influence public policy decisions. Representatives from interest groups are referred to as lobbyists (JBG). Lobbyist seek to bring virtually the passage or defeat of legislative bi lls and to influence congress, often using large sums of money in a variety of ways to influence legislative outcomes (APD). I feel that lobbyists have a great deal of influence within congress because they may have direct connections with congress members in senior high positions. Through PACs, organizations can pool campaign contributions from group members and donates those funds to candidates for political office. Personally, I feel that PACs have the most influence over congress because their ...

The Green Mile Essay -- Essays Papers

The Green knotFor my third quarter book report I read The Green Mile written by Stephen King. This book is about an old man, Paul Edgecomb, recalling his experiences when he worked as the cell block captain in Cold Mountain put in penitentiary. Paul was the cell block captain of death row in this Alabama correctional institute. This story takes place in a nursing home. The fibber Paul is writing a book about when he was cell block captain in 1932. During the time he is writing his book he points out how people never change, how there is always the bully, and so on. He compares writing the book to a time machine. Both seem to take him spur to 1932, and every lasdetail is clear.This book made me feel involved. As the reader you start off in the nursing home, with Paul, and ...

The First Descent of the Grand Canyon Essay -- American America Histor

John Wesley Powell was one of the fore virtually explorers in American history, and his first descent down the Colorado River through with(predicate) the Grand Canyon is one of Americas greatest adventure stories. Although he is not as well known as other explorers, his travels and his contri howeverions to American history are significant because they represent a spirit of discovery motivated not by self-glory or the acquisition of gold or land, but by a curiosity about and appreciation for both the natural world and the native peoples of the westward. John Wesley Powell pursued knowledge and the uncommon experience his integral life. Born in 1834 in Ohio to a Methodist minister, he became interested in science as a boy and was fortunate to have a neighbor who was both an amateur scientist and a willing teacher (Stegner 1314). In 1846, the Powell family moved to Wisconsin, where John Wesley struggled to continue his scientific education against the will of his father, who preciou s him to become a preacher. In 1857, he set off on his first great adventure a trip down the Ohio and Mississippi rivers in a rowboat (Stegner 16). In 1861 Powell enlisted in the Union Army and was elected captain of artillery under U. S. Grant. He was wounded at the Battle of battle of Pittsburgh Landing in 1862 and lost his right arm. Despite his debility, however, Powell returned to active duty and finished the war (Stegner 17). After the Civil War, Powell became a professor of science at Illinois Weslyan and curator of the Illinois State Natural History museum. In 1867 he went on his first expedition to Colorado and began his life-long love affair with the American West and the native peoples who lived there. The following year he went back to Colorado and spent the winter amon... ...de him fearless and victorious against hardship. Because of his unfaltering dedication to knowledge and the preservation of the West, Powell is truly one of the most significant American explore rs of the nineteenth century.
