Nuclear Bomb Testing essays

Nuclear Bomb Testing essays In their effort to create a bomb that would assure destruction of enemies, the world super powers of this century have created a legacy that could presumably destroy the entire world as we know it (Schull 6). During the course of the last fifty years, nuclear weapons have continually become an increasingly detrimental threat to our own health and environment. Consequently, laws have been proposed and bills have been signed to end this senseless build-up of arsenal and testing of havoc-causing atomic was instruments. Unfortunately, enforcing such rules worldwide has proven itself to be remarkably difficult and world allies have had to use extreme caution when dealing with any and all emerging threats. In the early days of nuclear weapons production, of course, not all safety hazards were fully appreciated,and possible threats to the environment went completely unrecognized. For this reason, we continued to tryout these deadly war tools without any major concern for our future. To be sure, it is understandable that in the race to produce the atomic bomb before Hitler, such considerations would come second. What is surprising is that this negligence should persist for 50 years thereafter, in spite of the growing awareness of the threats that technology and nuclear weapons production can pose. Even the challenge of cleaning up the results of four decades of nuclear weapons production from testing should be vast enough to tell us that testing must absolutely come to a complete stop around the world. Incredible resources will be needed to dispose of 2,700 tons of spent fuel, 10,500 hazardous substances, and 100 million gallons of high-level waste; to clean up 2.3 million acres of land; and to remediate 120 million square feet of buildings on 120 sites (Day 40-41). Four major tasks can be identified: to stabilize and maintain a large number of nuclear materials and facilities; to design, build, and operate a variety of treatment fac...

Shake the salt habit Essay Example | Topics and Well Written Essays - 500 words

Shake the salt habit - Essay Example The sodium in the American diet does not significantly come from the saltshakers but in the abundance of processed food consumption. It should be noted sodium is usually used to enhance the flavor, stabilize, and preserve processed food. Accordingly, sodium intake can be reduced by opting fresh, whole food closest to their natural state. Another option is to look for canned food which are sodium-free or with reduced-sodium content. The DASH (Dietary Approach to Solving Hypertension) eating plan, which prescribes a diet comprised of fruits, vegetables, whole grains, low-fat dairy food, and food with limited saturated fat, cholesterol and sodium, is clinically proven to dramatically reduce blood pressure by infusing enough levels of potassium in the body to counter the effects of sodium. It has been verified by the Tulane University Health Science Center that adequate potassium intake may lower systolic blood pressure by 3 points and diastolic by 2 points. The level of sodium in the body as well as its effect is tied to an individual's physiological sensitivity to salt.

Treatment plan - Case Study Example It is important to consider what a good group counseling can assist Sarah to cope with the death of her father and learn the importance of having friends. Also, to learn the importance of socializing and talking out issues affecting her. Group counselling, in the case of Sarah, mainly intends to heal the new family structure after the loss of her father`s life, who seemed to have been very close to her. Therefore, it is up to the group to assist her to know that her mother is now there with her to assist her and talk to her. The group is set to assist her manage the crisis situations in her life. The intention of group counselling is finding solutions to problems that are existent through sharing with one another. Sarah has the potential of improving in a group setting to help her deal with the trauma of losing her father, and also, assist with her other trauma-based problems like improving her personal communication and social skills. The advantages of group counselling for Sarah are fundamental for improving her social skills. Sarah has an awkward relationship with her friends because she withdraws from communicating with them, as well as a non-existent communication with her mother, and also, learning new ways from the members of the counselling group that assist her in coping with her acting out and fits of anger (Prout & Brown 2007). Sarah can benefit from group counselling as she is bound to realize that she is not alone. Group counselling is a great eye opener for Sarah to realize that there are others like her who experience the same problems as she is, and hence, develop a sense of understanding and coping with the problems. Group counselling gives the participant a better understanding and a wider perspective of the problem. The disadvantages in group counselling do not have effective leadership for the clients that are debilitating to the group members. It can result to

Direct Practice in Social Work Essay Example | Topics and Well Written Essays - 1500 words

Direct Practice in Social Work - Essay Example Therapy is likely to be most effective when a therapist is fully integrated into the treatment relationship; hence a therapist’s ability to fully and honestly express feelings and perceptions may be helpful in dispelling the notion of a â€Å"false front† being put forward by the practitioner (Clark, 2007:71). The objective of treatment is to gain authenticity in the therapist-client relationship, but these disclosures should be â€Å"purposeful and well timed† if they are to be beneficial (Clark, 2007:71). If on the other hand, such self disclosure is not purposeful and is done in a judgmental sort of way, it could be problematic because it could undermine the efficacy of the treatment and thereby, the therapist’s objective of gaining authenticity in the relationship. 2. The client Linda is a sexually abused person with a very negative perception of herself. Hence, it may be much better to focus upon the client herself and work towards helping her deal with her negative perceptions of herself rather than involving the therapist’s personal reactions to the client. Linda sees a rift between the therapist and herself, she perceives the therapist as being in a position of superiority. Hence if the therapist talks to Linda about her personal reactions to her client, then it needs to be done in a positive, focused manner. Rather than the therapist using a self involved statement such as â€Å"right now, I’m feeling a little cornered†, it may be more effective to couch the therapist reaction in a more positive and honest way. For example, if the therapist had responded more honestly by stating, â€Å"I have not personally been through such a shattering experience as you have but as I listen to you, I am impressed by the strength an d courage you have displayed in this situation. While you may feel that I am in a superior position, I tend to view this situation differently; I feel that you are far superior to me because you have displayed

Banana as a Natural Superdisintegrant

Banana as a Natural Superdisintegrant The objective of the study was to evaluate banana powder as a superdisintegrant for the formulation of oral disintegrating tablets and to compare the results with commonly used superdisintegrants like croscarmellose sodium, pre gelatinised starch and sodium starch glycolate. Oral disintegrating tablets containing Domperidone as the model drug were formulated using five different concentrations of each superdisintegrant (2%, 4%, 6%, 8% 10%) and compressed by direct compression. The formulations were subjected to various evaluation studies such as wetting time, water absorption ratio, disintegration time and in-vitro dissolution. The results showed that the disintegration time and drug release of the formulation containing banana powder (6%) was comparable to other super disintegrants. The IR spectrum analysis demonstrated that banana powder was compatible with the drug. These results suggest that banana powder can be used effectively as a superdisintegrant in orally disintegrating ta blet formulations. Banana, is a natural product which is available in plenty, economically affordable and has its own nutritional value. It can be used as a potential additive in the formulation of oro -dispersible tablets. Keyword: orodispersible tablets, superdisintegrants, disintegration time, natural excipients. INTRODUCTION The tablet is the widely used dosage form because of its convenience in terms of self-administration, compactness, and ease in manufacturing. For the past one decade, there has been a demand for more patient-friendly and compliant dosage forms. As a result, the development of new technologies has been increasing annually. Since the cost for development new drug molecule is very high, efforts are now being made by pharmaceutical companies to focus on the development of new drug dosage forms for existing drugs with more safety and efficacy together with reduced dosing frequency, and the production of more cost-effective dosage forms. However, geriatric and pediatric patients were having difficulty in swallowing conventional tablets, which leads to poor patient compliance. To overcome this problem, scientists have developed innovative drug delivery systems known as melt in mouth or mouth dissolve (MD) or sometimes dispersible tablets. These are novel types of tablets that disintegrate /disperse in saliva. Their characteristic advantages such as administration without water, lead to suitability for the geriatric and pediatric patients. They are also suitable for the bedridden patients, and patients who do not have easy access to water. The advantages, in terms of patient compliance, rapid onset of action, increased bioavailability (in some instances) and comparable stability to conventional tablets make these tablets popular as a dosage form of choice particularly in these populations. Domperidone maleate is a widely used anti-emetic drug, acting by inhibition of the dopaminergic receptor. Domperidone maleate does not cross the blood brain barrier. Domperidone maleate is also effective in gastro paresis, pediatrics gastro esophageal reflux (infant vomiting). Domperidone maleate after oral dosing undergoes extensive gastric and hepatic first pass metabolism resulting in low bioavailability (15%) which therefore, may not minimize the rate of vomiting. In context of the above principles, a strong need was recognized for the development of mouth dissolving tablets of Domperidone maleate to improve its bioavailability for relief on nausea and vomiting. In mouth dissolving tablets, disintegrants plays a major role. A  disintegrant  is a substance in a tablet formulation that enables the tablet to break up into smaller fragments upon contact with gastrointestinal fluids. Such a rapid rupture of the tablet matrix increases the surface area of the tablet particles, thereby increasing the rate of absorption of the active ingredient and decreasing the onset of time to therapeutic effect. A new disintegrant class has emerged during the recent past known as the Superdisintegrant. Superdisintegrants improve disintegrant efficiency resulting in decreased use levels, typically 1-10% by weight relative to total weight of tablet when compared to traditional disintegrants. The excipients added to the formulation should not only act as formulating agent it also act as good therapeutic agent and also free from toxicity. In the present research work an attempt was made to use banana powder as a superdisintegrant in the formulation of mouth dissolving tablets. Banana powder being a natural substance and rich in nutrition and availability can be an added advantage in using them as a pharmaceutical excipient. MATERIALS AND METHODS Materials Domperidone maleate was a gift from sterling lab (hosur,India) banana powder (self made) croscarmellose sodium (CCS) and sodium starch glycolate (SSG)as pharmaceutical grade was obtained from Loba chem ,mumbai, pre-gelatinised starch (PGS) as pharmaceutical grade was obtained from colorcon, Mumbai ,all other materials used were of suitable analytical grade. Preparation of banana powder: The unriped banana fruit was purchased from the local market. The fruit was cleaned and the peel was removed. Then the pulp was dried and powdered using mixer. The powdered substance was collected and stored in well closed container for further studies. Phase solubility studies: Phase solubility studies was done as per the method reported by (K.Venkates et.al,2009)2.Drug and superdisintegrant as per specified ratio (1:1,1:2,1:3,1:4,1:5) were weighed accurately and added to 25ml of water in screw capped bottles. All the bottles were shaken in Remi orbital incubator shaker at 370c with 100rpm for 24 hr. The container with drug and water was used as control. After 24 hr the solution was filtered using whatman filter paper (0.45 microns) .Then the filtrate was analyzed at wavelength of 284nm using Systronics TM double beam spectrophotometer. From the absorbance the solubility of drug was calculated. Compatibility studies: The compatibility study of drug with excipients was done using IR spectroscopy. The drug and the excipients were mixed in a ratio of 1:1 and stored in glass vials at 40 °C/75% RH for 30days. At the end of 30 days samples were withdrawn from each vial and the IR spectrum for those samples were taken. The samples were prepared by pressed pellet technique. The IR spectras was determined using JASCO FT/IR-4100 (3-4).16 scans were taken for each sample. The scanning range was between 4000-400 cm-1. The IR spectra of pure drug and pure excipients were compared to that of the mixture of drug and excipients and any interaction were analyzed. Microbial load for banana powder: Pour plate method was used to cultivate 1ml of banana powder solution with distilled water on muller Hilton agar medium for enumeration of bacteria and sarboured dextrose agar medium for fungi. The plate was incubated at 370c for 24 hours for bacteria while fungi plates were incubated at 270c for 72 hrs (3-6). At the end of the incubation period, the bacterial and fungal colonies formed were counted. Sterilized banana powder solution was taken as control. Swelling index: Swelling index was defined as the volume in milliliters occupied by 1 gram of superdisintegrant powder including any adhering mucilage, after it had swollen in water for 4 hour. The swelling index of the superdisintegrant was performed according to the (BP, 2007) method (7-9). In a 25ml ground- glass stoppered cyclinder graduated over a height of 125 ±5 mm in 0.5 ml divisions. About 25ml of water was added and shaken vigorously every 10 min for 1 hour and then allowed to stand for 3 hours. The volume occupied by the superdisintegrating agent including adhering mucilage was measured. The swelling index was calculated from the mean of three determinations. Pre-compression studies: All materials were mixed as per the composition shown in table1 and passed through 60 mesh sieve. The pre-compression studies (10-11) were done as follows. Bulk density: It is the ratio of total mass of powder to the bulk volume of powder. It was measured by Pouring the weight powder (passed through standard sieve # 60) into a measuring cylinder and initial weight was noted. The initial volume is called the bulk volume. From this the bulk density is calculated according to the formula. It is expressed in g/ml and the equation was given by Bulk density= mass/bulk volume (1) Tapped density: It is the ratio of total mass of the powder to the tapped volume of the powder. Volume was Measured by tapping the powder for 750 times and the tapped volume was noted if the difference between these two volumes is less than 2%. If it is more than 2%, tapping is continued for 1250 times and tapped volume was noted. Tapping was continued until the difference between successive volumes is less than 2 % (in a bulk density apparatus). It is expressed in g/ml and the equation was given by Tapped density= mass/ tapped volume. (2) Carrs index (or) % compressibility: It indicates powder flow properties. It is expressed in percentage and is given as Carrs index =Tapped density-Bulk density/Tapped density (3) Hausner ratio: Hausner ratio is an indirect index of ease of powder flow. It is calculated by the formula given below. Hausner ratio= Tapped density/bulk density (4) Lower hausner ratio (1.25). Preparation of tablet: All the materials were passed through 60 # screens prior to mixing. Domperidone maleate, Croscarmellose sodium (CCS), Sodium Starch Glycolate (SSG), Pre-gelatinised starch (PGS),Banana powder, Microcrystalline cellulose (MCC),Neotame (nutrasweet), Mannitol (DC) , Talc, Magnesium stereate and flavour ( pharmaceutical grade) were mixed using a glass mortar and pestle. The formulation without superdisintegrant was prepared and used as control. All the materials were directly compressed into tablets using concave face round tooling on a Rimek- rotary tablet machine at 12 rpm . The composition of the batches is shown in Table 1. INGREDIENTS Evaluation of tablet: Tablet hardness: The hardness of the tablet was determined by using Tab machine hardness tester. Weight variation: Twenty tablets were selected randomly from each formulation and weighed individually using a Shimadzu digital balance (BL-220H). The individual weight was compared with the average weight for the weight variation. Friability test: The friability of the tablets was measured in a Friability apparatus (Camp-bell Electronics, Mumbai). Tablets of a known weight (W0) or a sample of 20 tablets are dedusted in a drum for a fixed time (100 revolutions) and weighed (W) again. Percentage friability for each formulation was calculated from the loss in weight as given in equation below. Determination was made in triplicate. % Friability = W0â‚ ¬Ã¢â‚¬â„¢WÃÆ'-100/ W0 (5) Wetting time: A piece of tissue paper folded twice was placed in a small petridish (internal diameter = 6.5 cm) containing 6 ml of simulated saliva pH (phosphate buffer pH 6.8). A tablet was placed on the paper, and the time required for complete wetting was measured visually. Six measurements were performed for each batch (Nitin Jonwal et al, 2010). Water absorption time: A piece of tissue paper folded twice was placed in a small petridish (Internal Diameter = 6.5 cm) which containing 6 ml of phosphate buffer (pH6.8). A tablet was placed on the paper and the time required for complete wetting was then measured (Nitin Jonwal et al, 2010). The water absorption ratio (R) for the each formulation was determined using the following Equation. Water absorption ratio (R) =Waâ‚ ¬Ã¢â‚¬â„¢ Wb ÃÆ'-100 / wb (6) Where, Wb is the weight of the tablet before water absorption and Wa is the weight of the tablet after water absorption. Disintegration test: Disintegration test was done by using disintegration apparatus (camp-bell electronics, Mumbai)with distilled water as disintegration media at 370c and the time in second taken for complete disintegration of tablet with no palpable mass in the apparatus was noted visually (Nitin Jonwal et al,2010). In-vitro dissolution study: The release study was performed using (Tab machine) six stage dissolution rate apparatus (BP/IP/USP) paddle type with 900ml of 0.1N HCL (PH=1.2) as dissolution medium at 370c and 50rpm. The sample10ml was withdrawn with the time interval of 1, 2, 3, 4, 5, 10, 15, 20,25and 30 min. The volume of withdrawn sample was replaced with 10ml 0.1N HCL. The sample was filtered. Absorbance of the sample was measured using PC Based double beam spectrophotometer. The cumulative release was measured using equation obtained from standard curve. The regression co efficient of the standard was R2= 0.9997. RESULTS AND DISCUSSION: Phase solubility studies: The phase solubility studies was done as per the method reported by K .Venkates etal2.The solubility of drug was determined by increasing the concentration of superdisintegrant by specified ratio (1:1,1:2,1:3,1:4,1:5). The pure drug had a solubility of 0.2mg/ml whereas the solubility of the drug with added superdisintegrants showed a value of about 0.44 to 1.1mg/ml for CCS, 0.46 to 1.21mg/ml for SSG, 0.34 to 0.46mg/ml for PGS and 0.8 to 2.7mg/ml for banana powder. The above results suggested that on increasing concentration of the superdisintegrants the solubility of the pure drug tends to increase. Of the four superdistegrants used, banana powder showed the maximum increase in solubility of the drug. Compatibility studies: The drug excipient compatibility study was done by using JASCO FT/IR spectrometer. The IR spectra for pure drug, excipients and drug-excipient mixture were shown in Figure1. The pure drug showed characteristic absorption bands at 3127.97 (Aromatic CH stretching), 1487.81 (C=C ring stretching), 1147.44 (CH2 Alkane bending), 928.557 (RCH=CH2), 891,866,833 (Para substituted benzene) and the formulation shows characteristic absorption band at 3123.15 (Aromatic CH stretching), 1487.81 (C=C ring stretching), 1147.44 (CH2 Alkane bending), 928.557 (RCH=CH2), 891,865,833 (Para substituted benzene). The spectrum of the drug-excipient mixture was found to be a mere summation of the individual spectrum of the drug and excipients which suggest that there were no interaction between drug and excipients and were compatible with each other. Swelling index: The swelling indeces for the crosscarmellose sodium, sodium starch glycolate , pre-gelatinised starch, banana powder are presented in table3. The values obtained suggest that the swelling index banana powder is comparable to other superdisintegrant. Microbial load: The banana powder was a natural substance and so the microbial load test was done and the results shown that it contains microbial growth of about 253 cfu/gm and fungal growth of about 89 cfu/gm which was under the limit specified by (United state pharmacopoeia,2007) (5). Pre-compression studies: All the materials was mixed as per composition shown in table1.For each designed formulation blend of drug and excipients was prepared and evaluated for micromeritic properties and the obtained results were shown in Table3. The bulk density and tapped density for all formulation was presented in table 3. The hausners ratio and %compressibility index was found to be in the range of 1.14-1.28 and12-22% (Table 3). All formulation shows good blend property for direct compression and hence tablet was prepared by using direct compression technology. The results shows that formulation containing banana powder has better physical properties compare to other formulation (Table 3). Evaluation of tablets: The tablet was prepared by direct compression method as per Table1.The prepared tablets were evaluated for weight variation, hardness, friability, wetting time, water absorption ratio, as shown in Table4. The weight variation was found to be in the range of 248mg-253mg for all formulation .The hardness was found to be in the range of 2-3kg/cm in all formulation indicating good mechanical strength and it has ability to with stand physical and mechanical stress condition while handling. The friability for all formulation was less than 1% as per (British pharmacopoeia, 2007) . The wetting time is closely related to the inner structure of the tablet. This method mimics the action of saliva in contact with the tablet to illustrate the water uptake and subsequent wetting of tablet. This shows the wetting process was very rapid in almost all formulation. This may be due to the ability of swelling followed by breaking and also capacity of water absorption and swelling. The wetting time was found in the range of (Table4). Water absorption which is important criteria for understanding the capacity of disintegrants to swell in the presence of light amount of water was calculated. The tablets showed in the range of 12-100 sec (Table4). This shows all the formulation have good water absorption capacity. The most important parameter that needs to optimize in the development of mouth dissolving tablet is the disintegration time of tablet. In the present study all the formulations disintegrated within 1min. Table 5 give the disintegration time achieved by all the formulation. Four replicates were done. The disintegration time for tablet prepared with banana powder was much lower than the other synthetic superdisintegrants, indicating that banana powder has good disintegrant property (Table 5). Among the synthetic agents CCS was found to be having good disintegrating property than SSG and PGS. This rapid disintegration of banana powder and CCS was due to their rapid capillary activity and pronounced hydration with little tendency to gel formation . The results are in consistent with wetting and water absorption time. Dissolution studies: The drug release studies of the prepared formulations were done as per the method prescribed by British pharmacopoeia. The dissolution profiles of all the formulations were shown in Figure 2-6. It is clearly evident from the obtained data, that the tablet with banana powder as superdisintegrant showed excellent drug release as compared to other agents. It is clear that release of drug has improved considerably in formulation containing banana powder and CCS due to the rapid capillary activity and pronounced hydration with little tendency to gel formation. But the formulation containing SSG and PGS has less dissolution efficiency because it has more tendencies to form gel formation .The batch B3 containing banana powder (6%) and C3 containing CCS (6%) shows good dissolution efficiency and rapid dissolution compare to SSG and PGS. CONCLUSION The present study was aimed at evaluating the disintegrant property of banana powder in the formulation of mouth dissolving tablets. The obtained results clearly demonstrate the ability of banana powder as a superdisintegrant. The disintegration time obtained by tablets with banana powder wascomparable to that obtained with other commonly used disintegrants. Hence it can be used very effectively in the formulation of MDTs. Banana powder being a natural product with abundant availability can be used as a potential pharmaceutical excipient in various solid dosage forms especially in fast release products. The economical and nutritional value of banana powder will be an added advantage of using them in the pharmaceutical formulations.

Othello the Tragic Hero Essay -- essays research papers

Jealously, Often this trait takes people over, controls their thoughts and persuades them to do stupid things. William Shakespeare portrayed this flaw extremly well in the play Othello. IN the play, Othello, is a character who seems almost perfect, but his flaw jealousy is brought out but his trusted companion Iago. This trait makes Othello the tragic hero due to the fact that he sacrifices his life in good name. When being accused of â€Å"witchcraft† by Barbantio ( Desdemonas father) and senators he remains in control and courageous. â€Å" Most potent, grave, and reverend signors.... Rude I am in speech And little blessed with the soft phrase of peace† (1.3.91-97) This is an example of how he loves Desdemona truly . He explains this with style, control, courage, and grace. Also in (1.3.47) it is showed that he is respected â€Å"Here comes Barbantio and the valiant Moor.† Iago’s plot to ruin Othello starts to show up in the very beginning of the book when he angers Barbantio with the news of the Moors marriage to Desdemona ( Barbantios daughter). â€Å" I am one,sir, who comes to tell you, your daughter and the Moor are making the beast with two backs.†(1.1.128-131) This news angers Barbantio very much because he was not infromed of his daughters courtship to Othello and feels betrayed by Desdemona. Also he does not like the fact that Othello is of different race than he is. Another quote that shows Iago wants to ruin Othello is in Act 1 scene 1 line(s)4-42 â€Å"[S’blood,]but you’ll not hear me ....To love the Moor†.This quote shows Iagos hatred for Othello because he appointed Michael Cassio as his ancient and no... ...at he had killed his love. Iago winds up killing Emelia because she told Othello the truth about the handkerchief. Since Othello tires to kill Iago, but fails, he kills himself. Iago winds up going to jail to be tortured. Othello paid the ultimate price. His life. In conclusion Othello is the tragic hero because he was essentially perfect, except for his major flaw. Jealousy. This flaw eventually leads to his downfall, the killing of his faithful wife( contradictory to what he thought) and himself. This play should open everyones eyes about trusting people and having facts before you jump to conclusions. Remember jealousy is the green eyed monster that causes everyone you love pain and suffering. â€Å"O, Beware, my lord, of jealousy It is the green eyed monster wich doth mock The meat it feeds on† (Iago.3.3.194-196)

Educatinal Technology

1- ) Examine three (3) of the issues you feel are most important in shaping the role of technology in education. Analyze why they are most important ones The role of the education in this global world is increasing each day. There are a lot of ways, strategies and approaches to increase quality of education. One of most effective way is integrating technology in to the education. That is called educational technology.There are a lot of advantages of technology in the class but I will give information about three advantages of technology in the classes which are freedom, equality of the education and creativity. Technology in the education is giving more freedom to teachers and students. How? As a mathematics teacher in a public school I can give examples from my own experiences. I use smart board and smart pad in my classes. I prepare my lesson plan as software and I reflect on the board or on the screen. While I am walking around the class I can teach.I don’t have spent my ti me for writing the definitions or questions and cleaning the board. I don’t have turn my back to the students which is helping me for classroom management. As another example when I am teaching geometric figures even three dimensional figures now my drawing is not a problem anymore. With Mimio smart board I can visualize better. My students have more time to learn. And I put my class notes to website for students who missed the day or who couldn’t understand well. They still have chance review everything that they missed.I think this is the most important issue for role of the technology in the education. It is giving more time for teaching. It is another sole role of the technology in teaching, giving equal opportunity to all students. There are a lot of people who are seeking for education but they cannot reach it because of lack school or teacher . Maybe it is not common in U. S. A but around the world it is common. For these people technology is only hope. Or some people like me who have to support a family and want to get a degree; online education is the only way.With technology everybody has an opportunity to learn. For some special and minor issues technology is helping us so much too, for instance I have a student who is dyslexic. To make him focus to class and understand better tablet computers are very helpful. In my country Turkish Government is giving free tablets to all students. The last and I think most important benefit of the educational technology is increasing creativity. With standing front of the board and giving lecture we cannot individualize the education.It is a known fact every bodies learning way and level is different, from this perspective each person is unique. Especially if there is a big diversity in the class lecturing will not help. And if all students learn the same thing with same way it will not develop their creativity conversely it will decrease the creativity. To enhance students’ creativity we have to integrate technology in the education. With this way the students can learn with their own way and level. There is a web site that I use in my math applying classes (www. studyisland. om) , at the beginning of the year students are taking a diagnostic test and depends their results system is giving a unique way to each student, may be the system is not perfect but the idea is so beautiful. In twenty first century we are aware of that education is more complicated than we taught. Teachers are facing with different problems such as dyslexia, ADHD/ADD, asperger syndrome. To individualize education technology is very helpful. Increasing technology using will develop creativity ,freedom and opportunity in the education. ———————– Page | 1 Page | 1

Egyptian and Mesoptamian Creation Story Comparison Essay

The Egyptian and Mesopotamian civilizations are similar yet differ in the way in which they were created. Civilizations were created years and years ago with many mythological characters and beliefs. Religion, gender, culture, gods, and society are impact the creation of these civilizations. In each of these civilizations, â€Å"we† come from the same place, the Water. In the Egyptian creation story, the first thing that existed was the ocean. The ocean then laid an egg that hatched, Ra, the sun. Once Ra the sun was born, then came gods and goddesses, atmosphere, the Earth, and so on. In the Mesopotamian creation story, everything began with the water. From the water, sea monsters and gods were born. The gods then began to create life. The water played a huge role on the creation of â€Å"us† and who â€Å"we† are. Both the Egyptian and Mesopotamian civilizations believe in Polytheism. The Egyptian creation story takes place with many different gods and goddesses. Ra, the sun, brought these gods forth. The gods were Shu and Geb while the goddesses were Tefnut and Nut. Each of these gods was then the creator of something. In Mesopotamian society gods were brought to the picture, which then were the creators of everything. Gender played a picture in each of these creation stories. The stories differ on the roles of Gender. In Egypt, they had respect for women and were treated identical to men. For example, Shu, a god, and Tefnut, a goddess together created the atmosphere. The Mesopotamian’s take on gender was that male and female were not equal. For example, Tiamat, the female creator, tries to take control. Her descendants unite against her, choosing one of their number – Marduk, the god of Babylon – to lead them. In conclusion, the Egyptian and Mesopotamian civilizations are very similar. This leads me to believe that all civilizations are related when it dates back to the year in which they were created. These creation stories only differed in one major category, which were gender roles. Overall, the relationship between Egyptian and Mesopotamian creation stories were very similar.

The Ice Age Essays - Pleistocene, Mammoth, Permafrost, Tundra

The Ice Age Essays - Pleistocene, Mammoth, Permafrost, Tundra The Ice Age Twenty thousand years ago during the time of the last ice age period, many colossal mammals roamed North America. They survived during the times when much of the earth was covered by immense large bodies of ice that buried forests, fields, and mountains, but rapidly became extinct after the ice began to retreat and melt. Since then the human race has introduced many different theories to explain the extinction of these large mammals. One theory stands above all and explains the truth of this mysterious disappearance. The Paleo Indians that entered North America from Asia, the climate change, soil, vegetation and water levels were all major factors in this extinction. The results of these factors left the biggest impact on the food chain of these animals. The domino-effect of all these factors is responsible for the extinction of the ice age mammals. Animals, like all other living organisms have a tendency to adapt to the environment in which they live. A cold climate favors large animals, since large animals have more body fat and lose heat at a slower rate then do smaller animals. That is why many of the mammals that lived during the ice age were enormous. These large animals consisted of ground sloths and armadillos which came northward from South America, and horses, saber-toothed cats, mammoths, antelopes, and muskoxen that crossed over the land bridge from Asia into North America. For the longest time fossils from many parts of North America were the only evidence that many of these large beasts had once roamed the land, but in the spring of 1846 an unbelievable event happened that brought the world a step closer to the mystery of this great extinction. A Russian explorer Benkendorf and his survey team from Russia were heading for the mouth of the Indigirka River in Siberia. When they reached the spot of their destination, the land had disappeared and everything had changed. Left behind was two miles wide of torn up land, and wild waters carrying rapidly masses of peat and loam. In the mixture of the mess they seemed to notice what was once one of the mammoths who roamed the earth during the ice ages. (Chorlton 53) Our patience was tried. At last, however, a huge black horrible mass bobbed up out of the water. We beheld a colossal elephants head, armed with mighty tusks, its long trunk waving uncannily in the water, as though seeking something it had lost. Breathless with astonishment, I beheld the monster hardly 12 feet away, with the white of his half-open eyes showing. 'A mammoth! A mammoth!' someone shouted. (Chorlton 54) An elephant with a body covered with thick fur about thirteen feet in height and fifteen in length with tusks eight feet long that curved outward at the end. It had a trunk six feet long and colossal legs one and a half feet thick. The beast was fat and well grown. The outer hair was like wool, very soft, warm and thick, it was definitely well protected from the cold.(Chorlton 54) Unfortunately the mammoth soon began to decay and was swept away by the rapid waters. This dramatic find brought the world face to face with one of the great mysteries of the ice age, the sudden extinction of the great colossal mammals. These large mammals at one time lived in peace and survived gracefully for thousands of years, they adapted to the cold climate and tundra surrounding them. With an adequate food chain and nothing to affect it they were bound to survive forever, but because of simple changes that eventually triggered many other factors these animals are extinct and will never be on this earth again. When the massive continental glaciers locked up great quantities of water, the sea levels lowered which exposed parts of the shallow sea floor, therefore, the Bering Strait did not exist. Eleven thousand, years ago many Paleo Indians were able to cross the land bridge between Asia and North American which enabled them to populate North America. The great amount of large animals attracted these people to the frozen waste lands. In all hunting that ends with the extermination of a species, the motivation is never hunger. Money, and the greed for it, have been the incentive. The savage does not know these, he hunts to eat and so is unable to decimate the big game to any important extent (Cornwall 117) The large mammals of North American were never exposed
