Biflavone and a Plant Sterol Isolated from Antidesma bunius A Biflavone and a Plant Sterol Isolated from Antidesma bunius (Linn.) Spreng. Ivan L. Lawagai,* Suad Naheedb, Mohammed Mosihuzzamanc, Allan, Patrick G. Macabeoadeg, Erickson Paragasefk, Peter Prokschh, Alicia M. Aguinaldoaeg Catchphrases: Antidesma, Antidesma bunius, Amentoflavone, Betasitosterol, biflavone, sterols 1. Subject and source Antidesma bunius (Linn.) Spreng. (Euphrbiaceae) ‘‘bignay† is a typical plant found all through the Philippines. The bark is harmful as it contains an alkaloid in this manner, is utilized therapeutically. The leaves are acidic and diaphoretic, and, when youthful, these are overflowed with pot-herbs, and utilized by the locals in syphilitic diseases (Quisumbing, 1978). The leaves are sudorific and are utilized in rewarding snakebite in Asia (Morton, 1987). The leaves of Antidesma bunius, ordinarily known as â€Å"bignay†, are generally utilized by local Filipinos to control diabetes (Lawag et al., 2012). New leaves were gathered from the slopes of Brgy. Agustin Navarra, Ivisan, Capiz Province in January 2009. The plant was distinguished by Asst. Prof. Rosie A. Madulid and a voucher example (USTH 5357) is saved at the UST Herbarium, Botany Laboratory, Research Center for the Natural and Applied Sciences, University of Santo Tomas (UST), Manila, Philippines. 2. Past work Dammara-20, 24-dien-3î ²-ol and friedelin were disengaged from the stem and leaves of A. bunius (Hui and Sung, 1968). In 2008, Samappito and Butkhup distinguished the flavonoids catechin, Procyanidin B1 and Procyanidin B2 from the leafy foods corrosive, quercetin, catechin and epicatechin were additionally identified from the products of A. bunius (Santiago et al., 2005). 3. Present examination 3.1. Extraction and disconnection Dried and ground leaves Antidesma bunius (1610 g) were separated with 80% ethanol to give a green sweet concentrate (240.0 g) which was exposed to vacuum fluid chromatography (VLC) utilizing solvents of expanding extremity beginning with hexane, hexane-dichloromethane (1:1), dichloromethane, dichloromethane - ethyl acetic acid derivation (1:1), ethyl acetic acid derivation, ethyl acetic acid derivation methanol (1:1), and methanol to give seven parts. The fifth division (4.04 g) was additionally fractionated twice on silica gel pressed on VLC utilizing solvents of expanding extremity beginning from hexane and consummation with methanol giving five parts each, separately. Portion three which was sanitized twice on silica gel utilizing hexane-dichloromethane (1:1) and hexane-dichloromethane (95:5) outfitted 1 (16.13 mg). Confinement of 2: the fourth division (12.34 g) after VLC was chromatographed on silica gel utilizing 5-10% angles of methanol in dichloromethane to give ten portions. Division three (42.3 mg) was additionally sanitized utilizing Sephadex LH20 utilizing 20% inclinations of methanol in DCM to give 2 (5.9 mg). (1)(2) 3.2. ID of filtered mixes The mixes were recognized as Stigmast-5-en-3î ²-ol or ÃŽ ²-sitosterol, a plant sterol, (1) (Balamurugan et al., 2012) and (Sosinska, et al., 2013) and 3,8-biapigenin (Amentoflavone), a biflavone (2) (Chari et al., 1977) and (Ryu et al., 2010) based on their IR, LR-EIMS, LR-ESIMS and NMR (1H NMR, 13C NMR, 1H-1H Cozy, HMBC and HSQC) otherworldly information and by correlation of spectra reports with the writing. 4. Chemotaxonomic noteworthiness Other Antidesma species like A. menasu (Risvi et al., 1980a), (Risvi et al., 1980b) and A. pentandrum (Chen et al., 2004), (Kikuchi, 1983) are known to contain plant sterols. A. puncticulatum is known to contain flavonoids (Nuengchamnong and Ingkaninan, 2009), while A. laciniatum was accounted for to contain both plant sterols and flavonoids (Tchinda et al., 2006). The separation procedure that was directly preformed on the ethanolic leaf concentrate of A. bunius managed mixes 1 and 2 which were lucid to the exacerbates that were recently segregated or detailed from the other Antidesma species. Despite the fact that the said mixes were accounted for the absolute first time in A. bunius, compound 1 was additionally answered to be available in A. pentandrum (Chen et al., 2004) and in A. laciniatum (Tchinda et al., 2006), while compound 2 was accounted for to be available in A. laciniatum (Tchinda et al., 2006). This further builds up the chemotaxonomic relationship of A. bunius towards different types of the family Antidesma. In spite of the fact that plant sterols (Hui and Sung, 1968) and biflavones (Samappito and Butkhup, 2008), (Santiago et al., 2005) were recently announced in the leaf and bark removes A. bunius, this is the primary report that demonstrated the nearness of ÃŽ ²-sitosterol (1) and Amentoflavone (2). Mixes 1 and 2 along these lines signify the rundown of secluded and recognized mixes from the leaves of A. bunius. References Quisumbing, E., 1978. Therapeutic Plants of the Philippines.

5 Exam Study Tips for Students With ADHD

5 Exam Study Tips for Students With ADHD Studying for exams can be a very stressful experience when you have ADHD. You might find you spend much more time studying for exams than other students, yet your grades do not reflect your effort. This can leave you feeling disappointed, frustrated, and demotivated. Four challenging areas are: Deciding what topics are most important to studyStudying for the exam in the weeks leading before the exam (rather than waiting to the last minute)Being able to sit down and focus on studyingReading and remembering the material Here are some ADHD friendly tips to help you study for your exams.   1) Connect With Your Teacher at the Beginning of the Semester Preparing for exams starts early!  At the beginning of the semester or school year, make a point of introducing yourself to your teacher.  A positive, communicative relationship with your teacher or professor can make a big difference, especially if they are knowledgeable about learning issues that can be associated with ADHD. If not, share with them what areas are more difficult for you and the strategies you are using to help with learning. This lets your teacher know you are being proactive and are invested in doing well in class. It also corrects any misperceptions the teacher may have as sometimes ADHD behavior can look like you are not motivated or interested, such as arriving a few minutes late for class, gazing out of the window or missing a deadline. Class Notes Taking notes in class can be hard when you have ADHD. If you are eligible for student accommodations, you might be given a scribe.  This is when the office of student disabilities arranges for a student in your class to give you a copy of their notes. However, if you do not get this accommodation formally, why not identify a student in the class who is organized and good at note-taking, and ask if they would be willing to share notes. Getting the class notes is an important part of preparing for exams. 2) Approximately 1 Month Before the Exam As an exam date moves closer, ask your teacher for specific information about what topic areas will be covered on the exam. For example:Which chapters or readings will be in the exam?Will the lectures be the primary source for the exam?If your teacher has given out a review sheet, ask for their help so you can prioritize areas to study. If you don’t have a review sheet, gather together handouts, old quizzes, assignments on the topic and the class syllabus. Bring these with you when you meet with the teacher to get help in prioritizing areas of study for the test. Format Ask the teacher about the format of the exam and what type of questions should you expect. Will it be multiple choice, essay, or sets of problems to solve? Will you need to memorize facts or apply them? Will you need to define terms, compare and contrast or argue and support points? This will give you more information about how to study. Planning Some students skip the planning phase because they want to use their time to study. However, planning takes a relatively short amount of time, and it will help you avoid all-nighters and anxiety the exam day approaches. During your planning time, break down the material you need to study into manageable chunks so it doesn’t feel so overwhelming. Get help doing this if you need it, perhaps a friend, tutor, teacher, coach, or parent. Set up an exam study schedule. Decide what you will study first. Some people do better getting the harder, less known areas of study out of the way first. Others feel more motivated when they are able to get easier or more interesting aspects completed first. For many students with ADHD, getting started and staying focused while studying is a big part of the equation. Planning when you are going to study and what you will study at that time helps reduce procrastination and aids focus. How to Study When it is time to study, work in short blocks of time and then take a mini break. For example:Set a timer to go off after 30 minutes of studying (or whatever amount of time works best for you) and then take a break.During your breaks, get up and walk around,  or even do some jumping jacks.Then study again for another 30 minutes. Some students find that a small reward after a period of study helps to motivate them to study. Location Find a study area that helps you to focus. For some people that is a place that is free from distractions. Other students find they can concentrate best in a busy area, such as the library or a coffee shop. Other people like to vary their location. Learning Strategies Think about your learning style and how to match it up with the material you need to learn. Simple flashcards made from index cards are often helpful when you need to memorize terms, definitions or theories.Outlines are helpful in preparing for essay exams. Other ideas that can help you retain information include: Drawing diagrams and pictures  Explaining the concepts to a friendWriting or hearing the material again and againUsing mnemonics for difficult-to-remember information Study Groups There are pros and cons to studying in groups. When they are organized and focused, they can often improve learning. If larger groups are uncomfortable, you might find that studying with a friend helps you stay on track. “Teaching” the material to another student can also aid in learning. Tutor You may also want to explore the possibility of a tutor to help you organize your thoughts, prioritize study topics and help keep you focused. 3) The Night Before Exam Day Pack your book bag with all your necessary items such as pencils, paper, id, energy bar, water, and anything else you’ll need and set it by the door.Instead of staying up all night studying, go to bed and get some sleep. 4) Day of the Exam Eat some protein for breakfast.Arrive at the exam room a little early so that you will feel calm and organized.Good luck! 5) After the Exam Once you get the exam back, arrange a time to meet with your teacher to review your results. Ask for feedback on how you might have responded more comprehensively on essay sections and for any other recommendations your teacher may have to help. Advocating for yourself in this way not only helps give you more information about what you can do to improve your performance on the next test, but it also lets your teacher know you are invested and motivated to learn.

Essay on Wealth and Poverty Karl Marx - 1711 Words

We will write a custom essay sample on What is language or any similar topic only for you Order Now Candela et. Al. 2012: 1-2) By working through your tutorial matter (study guide and textbooks), you should be able to provide answers to these questions. What Is language? Language is â€Å"the method of human communication, either spoken or written, consisting of the use of words in a structured and conventional way. â€Å"l What is communication? Communication is â€Å"the imparting or exchanging of information by speaking, writing, or using some other medium. â€Å"2 In order to communicate (for people to understand one another) we need to use language in a structured manner. Consider the following sentences: ) I am happy because I ate chocolate. ) Chocolate I happy I because ate am. C) I ma yap succubae I tea teleological. 1 OFFS Why do you understand the first sentence? Why are the second and third sentences unintelligible? For meaningful communication to take place, we need to understand and apply the rules of the particular language we are studying. In this module, we lea rn about some of the rules which govern the English language. You will learn words, sentences and ideas that will help you to describe language. These words and ideas will be applied to real life situations where English is used. Consider how English is used in different situations: school, work, home and Twitter. You will begin to appreciate that language use varies from one context to another. As yourself the question; would you talk or write to your employer in the same way that you would address your friends? You will be introduced to the technical language terminology (such as â€Å"syntax†, â€Å"phonetics†, â€Å"phonology’, â€Å"register†, â€Å"genre†, â€Å"text†, â€Å"semantics† and â€Å"pragmatics†) in order to study language. Since you do not generally use language in isolation, we need to investigate how it is used in society. Remember that not everyone uses language in the same manner.

If you refer to the dictionary, there are many definitions provided for â€Å"text†. For example, a â€Å"text† could refer to â€Å"a book or other written or printed work, regarded in terms of its content rather than its physical form. â€Å"3 In your study guide, we learn that â€Å"text† does not refer exclusively to written material.

The news that we hear on radio, or the news that we watch being broadcast on Television. A text can also be visual or audio-visual. Indeed, texts that are produced for television are audio-visual. Similarly, some written texts combine both the written and the visual, e. G. Newspaper reports. An art painting, such as, (Candela et. Al. , 2012: 3) Example of a text: Mona Lisa Leonardo dad Vinci Why do you think a painting can be regarded as a text? Provide other examples of texts. What is a domain? One definition for â€Å"domain† is â€Å"a specified sphere of activity or knowledge. â€Å"4 In your study guide, we learn that a â€Å"domain† does not refer exclusively to written Domain refers to social categories which locate all instances of language use in various situations or contexts. It can be the classroom domain, the sports field, a church, a political rally, etc. Notice that a classroom belongs to the larger sphere or domain of education, and a sermon in church belongs to the larger domain of religion. (Candela et. Al. , 2012: 4) Provide examples of a domain. Why is it important to identify a domain? ? Earlier, I provided a dictionary definition of language. On page 4 of your study guide, there are other definitions of language. In this module, language is viewed as a system of relating forms to functions. What does this mean? Firstly, can you identify the constituents of a sentence? I. E. Can you identify a verb, adverb, noun, adjective and so forth? Sentence. If you can identify these forms and how they function in a sentence, then you will begin to understand how they produce meaning in a text. Language is like a machine. If any parts are missing or are in the wrong place, the machine will not work. The following table from the study guide represents the language system: Language concept Meaning Phonetics The study of speech sounds. Phonology The study of the sound patterning system. Lexis The study of the actual words a writer or speaker chooses to use. Morphology The study of how words are formed. Syntax The study of how words combine to form sentences and the rules that govern the formations. Orthography Writing systems Semantics The study of meaning, how meaning is made and understood. Pragmatics The study of the use of language in communication – I. E. Sentences as used in contexts and situations. Discourse How to cite What is language, Papers What is Language Free Essays The question above at first glance seemed easy to answer especially that we all have preconceived idea of what really language is. Language is talking. Noam Chomsky contends that more than any other characteristics, the possession of language distinguishes humans from animals (Chomsky). We will write a custom essay sample on What is Language? or any similar topic only for you Order Now He argued that to understand humanity, one must understand the nature of language that makes us human. Language is not merely the ability to talk, rather, it is the capacity to produce sounds that signify certain meanings and to understand or interpret the sounds produced by others (Chomsky, p. 2). Thus, if one do not know the language, the words of that language will be mostly inconceivable. Language is more than speech as deaf people can produce languages without words just as normal persons generate and understand verbal languages. Language is what makes people understands each other, it is makes nations to unite for a common goals and it is the very foundation of progress and achievements. Thus understanding language is an essential task that every one must undertake. The world has perhaps thousands of different language that for most of us we can only speak five or the most is ten of these languages. Our limited knowledge of such languages is hindering us to achieve our goals to live in peace, unity, and, in cooperation with each other. Linguistic study therefore is an essential step towards this purpose of achieving, unity, cooperation, and mutual understanding with each other. Knowing what is Language Knowing a language involves knowing what sounds are in that language. It means that when one is not an English speaker he or she cannot substitute the pronunciation of a certain word to make it appear the word is pronounced in English. Taking for example the case presented by Chomsky, he noted that French people often pronounced the English word this and that as if they were spelled as â€Å"Zis† and â€Å"Zat. † knowing the sound system of the language therefore includes more than just the record of sounds. It involves knowing which sounds may start a word, end a word, and follow each other. According to Chomsky, knowing the sounds and the patterns of sounds amount to only one part of our linguistic knowledge. While it may be true that certain sequence of sounds denote certain concepts or meanings, if this is the case, knowing a language is not an easy task. One has to learn the sequences of sound if he or she has to learn language. That is, the words in that language which is also the sound sequences that are related to particular meanings. Thus, if one do not know a language, he or she cannot understand the meaning of the words or sentences of that language, because the relationship between speech and sounds is very subjective or an arbitrary one. Acquiring a language therefore needs one to identify that the sounds represented by the letters signify the concept. Sign Languages The relationship between form (sound) and the meaning (concept) of a word is true even in sign languages (Chomsky, p. 5). It is doubtful someone who is using Chinese sign language CSL) can comprehend the message of the one who is using American Sign Language (ASL), the same with the other. The author noted that not all the movements of the hands reveal the meaning of the gesture in sign languages. He point out that there is some sound symbolism in language, which is the words whose pronunciation suggest meanings. These words or sounds in a language sometimes imitate other sounds, however, although there may be some sounds that are similar to the objects or actions they refer to, the sounds differ from language to language because each language has its own particular system of language. However, Martin Hann emphasized that in understanding the message of the language both the sender and the receiver needs shared meanings of the gestures tones, and other communication symbols (Hann, M. . Hann pointed out that all the information and messages that we receive is being organized by our minds into a mental map that correspond to our perception of reality. The Importance of Sound Sequences To some extent, the author noted that some particular sound sequences seem to relate to a particular notion. Citing as example, the English words beginning gl such as glare, glint, gleam, glitter, glossy, glaze, glimmer, glimpse, and so forth, seemed to be related to sight. However, another set of words beginning with the same two letters, such as gladiator, glucose, glory, glutton, etc. ave nothing to do with sight. The point here is, it is important to know the sound sequences that relate to a particular idea. It does not matter for any one even if he or she can memorize all the 472,000 entries in the Webster dictionary unless he or she can learn the uses of each of those words. In other words, one cannot learn to speak foreign language by buying a dictionary and memorizing all the words, because one will not be able to construct even a simple sentences or phrase in a particular language that can be understand by a native speaker of that language. To understand the words in a language it is important to know where the words begin and where it ended. The Linguistic creativity As some one said, language is a gift of God to humanity. It is through language that humans communicate with each other regardless of race, and nationality. However, we cannot deny that there are language barriers to this communication. One of the most identified barriers is culture diversity. Portland State University, Sociology professor Sharon Lee noted that culture includes language and communication system and is often been used as alternative for culture (Lee, Sharon 2003). The language barrier caused by our cultural differences divides us in many aspect of our civilized social life because everyone has a unique perception and the ideas or the messages, and gestures being expressed differ from others. . Hence, the linguistic creativity is an essential initiative understanding language. Knowledge of language made it possible to combine sounds to construct words and to form phrases to make a sentence of the language. Knowing a language then, means being able to construct sentences and to understand sentences never heard before. This ability to construct and to understand sentences in a language is referred to as the creative aspect of language use. Linguistic creativity is a knowledge hungry process in which metaphors, poems, and jokes are just some of the typical forms. However, our creative ability is reflected not only by what we say, but it also includes our understanding of new sentences (Chomsky p. 9). Linguistic Knowledge and Performance The rise of linguistic in the 19th century has led to the formation of linguistic as a science, which means that linguistic is now a study. For Noam Chomsky Linguistic competence is a linguistic performance, which suggests that it is a process towards achieving such objective. For Chomsky, linguistic competence is the knowledge that we have of a certain language, or the ability to speak such language, which in turn becomes our linguistic performance. In other words linguistic competence and linguistic performance are basically inseparable. That is, When one is linguistic competent, it is a result of a long process of studying language. One’s mastery of language therefore as a result of such study is the linguistic performance. However, For Chomsky, linguistic competence is the unconscious knowledge of grammatical system. The linguistic system such as the sounds, the structures, words, and rules for putting them all collectively is acquired with no conscious awareness. Chomsky emphasized that we are unaware of the rules of language. Our knowledge of the rules of language is revealed by our ability to speak and understand, and to make judgment about the grammaticality of the sentences. Roumyana Slabakova and Silvina Montrul noted that grammatical competence is the unconscious, inherent knowledge that a speaker has about language. The Use of Grammar Grammar according to Chomsky has been defined as â€Å"that which authorized us either to converse a language or to talk about a language. † The way we use the word grammar differs from it most common usage. For Chomsky, grammar includes the knowledge that speaker have about the rules of the language for combining sounds into words which is called phonology while the rules of forming a word is called morphology and the rules for combining words into phrases and phrases into sentences is called syntax, the rule for giving meaning is called semantics. Linguistic competence in this regard is the ability to understand the nature of grammar, which then lead to the understanding to the understanding of the nature of the language. There are two ways linguist use grammar, first, grammar refers to the mental grammars that speakers have in their brain. The second is the model or the linguists’ description of this internalized grammar. Grammatical sentence according to Chomsky is when it conforms to the rules of the mental grammar and the so-called ungrammatical sentences are those who deviate from the rules in some ways. However, Chomsky pointed out that every language variety has its own grammar and no language is superior to any other language in linguistic sense. That is every grammar is equally complex, equally logical and capable of constructing an endless set of sentences to express any thought that can be equally expressed in any other language or dialect, too. It may me expressed using different words, phrases, and sentences, but what is important is that it can be expressed. However, not every grammarian shared that all grammar are equal as there are those who believed even from the earliest times that some account of language are better than others and that there are correct forms that the educated people should use in speaking and writing, and to change language is corruption. Among those who shared this view were the Alexandrians in the first century, the Arabic scholars at Basra, in the eight-century, and the combined batch of numerous English grammarians of the eighteenth and nineteenth century. Chomsky contends that these people wished to prescribed rather than describe the rules of grammar that paved the way to the rise of the writing of prescriptive grammars. This prescriptive grammar has become the language grammar of the upper classes. Conclusion Language is very important regardless of how others would view it. There are may be language for the elite rich and famous, or for the intellectuals, or even for the street people. What ever, language we use, the most important is we understand the people whom we are talking with. It is where that language is said to be a gift, for if we cannot understand others merely because they do not speak our language does not constitute is what is meant of misunderstanding. While I believe in the importance of leaning language but it should not be a hindrance towards understanding each other. However, for the improvement of our society and we must all strive to learn as much language as we can. In this way we can communicate well and can understand each other well. There is nothing wrong ig we utilized our ability to learn language instead, there plenty of benefits if we do so. How to cite What is Language?, Papers

IT System and Analysis

Question: Explain IT System and Analysis. Answer: Data flow diagram The data flow diagram for response and reporting system are as Figure 2: DFD for enquiry request and response between training and employee reporting process Process used by analyst for analyzing data oriented systems As mentioned by Bauer, Vom et al. (2009), data oriented systems help system analyst to complete the process is structural manner. The data oriented system used by system analyst for analyzing enquiry request and response system is data flow diagram Vom et al., (2009). Zero level data flow diagrams help the system analyst to decide the complete procedure of enquiry approval and analysis Kusic, G. (2009). As commented by Goetz (2010), data oriented diagram help system analyst to analyze each and every process. The request and response process of every enquiry involves many steps (Mortazavi Jalili, 2014). Every person involves in request and response processes are having their own set of responsibilities Mortazavi Jalili (2014). As a system analyst of MRE Corporation, analysis of each process is very important. It helps in improving the enquiry and response system of company. Use of decision tables, trees in structured decision process As commented by Grabczewski (2009), the structured decision making process involves several steps. As a system analyst of MRE Corporation, for making decision flowcharts, data flow diagram and others are used (Vom et al., 2009). It helps in making structured decision, that is, decision which involves step by step process. In context to this Kusic (2009) stated, every top level and middle level manager play important roles in the decision making process. On the other hand, the decision tree helps in analyzing the process, by using different graphs and models. As mentioned by Mortazavi Jalili (2014), decision tree help in analyzing the decision and making changes in it. As a system analyst, decision is taken after analyzing the complete problem and the reason (Vom et al., 2009). Decision tree help in making structured form of all process and people involved in decision making process. Analysis method used for analyzing structured decisions and for creating process of specifications As commented by Omer (2013), structured decision process involves step by step process. Structured decision making can only be completed, when all process are completed on time. The enquiry request and response system decision can only be completed with the help of decision tree and tables (Mortazavi Jalili, 2014). For example, suppose training request is raised for few employees from training department (Vom et al., 2009). Then the final decision for training will be taken after analyzing the requirement of training. To explain who request process to managers system analyst has to create decision tree and tables.
