ASSIGNMENT OF SEED PROCESSING ON GRAVITY SEPARATOR AND COLOR SORTER Submitted to Dr. Yadvika Submitted by Aman Dhillon 2009AE05BIV Color Sorter Separation Principle Electronic color sorters separate seed by differences in color. Each seed is viewed and electronically compared with a pre-selected color background‚ and accepted or rejected. The color sorter can also separate off-color mud balls‚ other seed kinds and discolored or other-variety crop seed whose color is different from that

da Alvarenga Lab Partner: Keren Appiahene Mussie Gide 10 September 2016 Experiment 2: Acid- Base Extraction Separation of an Organic Acid‚ a Base and a Neutral Compound Introduction: The extraction technique is often used in the organic lab to separate organic compounds from mixtures. One type of an extraction technique is the acid-base extraction‚ which is used to separate organic compounds from a mixture based on their acid-base properties.1 There are certain principles that must be taken into

Introduction: Recrystallization is used for the purification of solid compounds. The recrystallization process relies on the fact that majority of compounds are more soluble in hot solvent than in cold. The hot saturated solution containing the compound will have unwanted impurities and will be filtered out and cooled to produce the pure crystal constituents of the compound. Thin layer chromatography can be used as a physical method to segregate compounds from natural sources. E.g. Spinach

Experiment Separation of Organic Compounds by Acid-Base Extraction Techniques 5 A commonly used method of separating a mixture of organic compounds is known as liquid-liquid extraction. Most reactions of organic compounds require extraction at some stage of product purification. In this experiment you will use extraction techniques to separate a mixture of an organic acid‚ a base‚ and a neutral compound. Organic acids and bases can be separated from each other and from neutral compounds

For many divorced and separated parents with children there will be a common answer as to why they ended up with the child custody and visitation arrangement they have. The answer being‚ "the judge decided it." In other words‚ the judge chose the parenting arrangement you have based on his/her belief of what was in your child’s best interest. Judges do not always make the child custody decision or choose the parenting plan arrangement for the parent’s. In fact‚ more often than not‚ the judge will

Theoretical Framework Tinto’s Theory of Departure. Tinto (1975) introduced the concept of retention where it says that “students who socially integrate into campus community increase commitment to the institution and are more likely to graduate. This theory focuses on how students’ lack ofinteraction within the higher education community leads to student departure.. Based on Van Gennep’s (1960) anthropological model of cultural rites and passages‚ “students must separate from former groups‚‚ undergo

The Separation and Purification of Organic Compounds Sunshine Marie Introduction Each year‚ many thousands of new or unknown organic compounds are prepared or extracted from natural sources such as plants‚ fungi and animals. In order to identify an unknown organic compound or the components of a mixture of organic compounds‚ it is necessary firstly to separate and purify the compounds. At any given temperature‚ a certain number of molecules of a substance in the liquid state have sufficient

As we know‚ the TLC is a separation technique that has two phases: the stationary phase and mobile phase. The stationary phase is silica gel (SiO2) which is very polar compound‚ while the mobile phase is 0.5% acetic acid which has less polar. Also‚ as we know‚ the compound will rather to stay with stationary phase or travel with mobile phase depend on its polarity. The result show as that the polarity of the solvent is the key factor for the compound to travel with it or stay in stationary phase

Separation and Identification of Plant Pigments by Paper Chromatography Biology 1107L Introduction All living organisms require energy for their chemical processes. The ultimate source of this energy is the sun. Plants convert light energy into the chemical energy of sugars. During photosynthesis pigments are used to capture light energy. Pigments of green plants can easily be separated and identified using a technique called paper chromatography. The purpose of this

The Alexander Technique evaluates and explores the opportunities of it being an effective and safe technique that can be integrated as a holistic healing modality within the nursing practice and self-care. “The Alexander Principle states: that there are certain ways of using your body which are better than certain other ways; that when you reject these better ways of using your body‚ your functioning will begin to suffer in some important respects; that it is useful to assess other people by the
