biodegradable alternative to synthetic adhesives and reduce waste simultaneously. Scope and Limitations of the Study Only pili nut shells and pulp shall be used in the experiment. The shell and pulp extracts shall be obtained through Soxhlet extraction using Hexane (C6H14) as the solvent. After which‚ the resulting extracts shall be separated from the solvent through distillation‚ separately. The obtained pili nut shell extract and pulp extract shall then be tested in 30%‚ 50% and 70% concentrations

Objectives: * To identify the increasing rate of ground water extraction for city dwellers. * To study the consequences of groundwater extraction. * To find out alternative options of water for city dwellers. Research question: * What is groundwater? * Why rapidly ground water is facing extraction? * What about current rates of ground water extraction? * What are the consequences of groundwater extraction? * Is there any alternative option of water supply for city

Lab Report (Scientific Paper) 2: Bacterial Transformation;DNA Extraction Part I & II:Total Genomic Extraction & Plasmid Extraction;Electrophoresis By:Chris Foster Abstract: We conducted three experiments that included a Bacterial Transformation‚ a two process DNA extraction‚ and a final procedure using gel electrophoresis. The Bacterial Transformation lab was performed to prepare the plasmid into a bacteria and to use that bacteria to amplify the plasmid in order to make large quantities

The seed cake remaining after oil extraction may be used as a fertilizer or as a flocculent to purify water. Moringa seed oil also has potential for use as a biofuel. Previous researchers have extracted Moringaoleifera oil by using different methods such as solvent and aqueous enzymatic extraction (Abdulkarim et al.‚ 2005) but focussed on the study of the physicochemical properties of the oil obtained. Information on the influence that oil and oil extraction method could have over the primary

or nitrogen starvation‚ as well as two different extraction options‚ dry or wet extraction‚ have been tested. The best scenario has been compared to first generation biodiesel and oil diesel. The outcome confirms the potential of microalgae as an energy source but highlights the imperative necessity of decreasing the energy and fertilizer consumption. Therefore control of nitrogen stress during the culture and optimization of wet extraction seem to be valuable options. This study also emphasizes

ESTIMATION OF COLCHICINE:In the first method for extraction (Method 1)[1]‚ 0.5 g of powdered plant material was extracted twice with 25 ml of petroleum ether with frequent shaking for 1 h‚ followed each time by filtration. The solid residues were air dried and then extracted with 10 ml of dichloromethane at room temperature for 30 min with frequent shaking. Then 10% solution of ammonia (0.5 ml) was added to the mixture with vigorous shaking for 10 min; the mixture was left undisturbed for 30 min

Shredding and grinding tires: By shredding‚ the volume of scrap tires can be reduced to about ¼‚ thus reducing space requirement and shipping costs. Tire shredding can be considered a mature technology now in North America. Products: Rubber Crumb (sellable product – serves as raw material to many many industries) Finer synthetic and natural rubber (obviously after treatments) which can be used in Tiles and tile adhesives‚ mixing with asphalt‚ sports surfaces‚ carpet underlay‚ noise and vibration

The third set of molars‚ known commonly as wisdom teeth‚ normally grow in between the ages of 17 and 21. Unfortunately‚ wisdom teeth can cause a variety of oral problems‚ making it necessary to remove them from the mouth. Tooth extractions for teenagers are a common concern among parents and teenagers. Why Does My Teen Need to Have Their Wisdom Teeth Removed? There are a variety of reasons that may require having your teen’s wisdom teeth removed: Impacted wisdom teeth can become trapped in the

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 by extraction using aqueous solutions of different pH values. Most organic carboxylic
