University General Santos City Bio 108: Cell Biology Laboratory Report August 28‚ 2013 DNA Extraction on Onion (Allium cepa) and Human Cheek Cell Arriza‚ Rolland Merch Buscato‚ Carl G. Butil‚ Conrad G. Leonida‚ Renee Theresa ABSTRACT This activity observes the DNA present in onion (Allium cepa) and human cheek cells by extracting it with the addition of lysis buffer and chilled ethanol. The lysis buffer is prepared from squeezed onion mixed with salt and Pantene Pro-V Shampoo. The buffer

the search for alternative fuels‚ with the experts from the University of the Philippines in both Diliman and Los Banos campuses searching all over the archipelago for energy sources from the forests to the bottom of the sea‚ from enzymes to fungi and other microorganisms. So‚ the researcher came up of using the malunggay leaves extract as source of ethanol since based on the study done by Senator Loren Legarda‚ the extracts obtained from the leaves of malunggay plant is 80% ethanol‚ which is used

higher-boiling compounds behind in the mixture. By isolating the vapor produced at different temperatures and condensing them (i.e.‚ converting gases to liquids)‚ you can effectively separate and purify compounds based on their boiling points. While there are multiple factors that contribute to the efficiency of distillation‚ the first‚ most obvious is the boiling points of the compounds themselves. If one compound is significantly more volatile than another (∆bp > 40 C)‚ then the compounds can be effectively

EXTRACTION OF COPPER FROM OXIDISED COPPER ORE Aim: To analyse how copper is obtained from oxidised copper ore using the processes of leaching‚ solid-liquid separation‚ displacing and electrowinning. Method: Refer to ‘Extraction of Copper from oxidised Copper Ore’ document pages 1-2 Results: Leaching: The blue particles in the copper ore which is copper was dissolved in the sulphuric acid and the solution turned into a blue colour. There was also sediment that was floating around

Truth be told‚ there is. Caffeine is renowned for being the world’s most widely consumed psychoactive drug‚ but it is also known for literally shaking up our bodies by affecting our nervous systems. The drug can be good for us in some ways‚ but also bad in other ways. This makes it tricky and debatable whether caffeine is more helpful or more harmful. Inside the neurotransmitter‚ caffeine causes receptors to receive more dopamine chemicals by blocking off adenosine chemicals from getting through. Adenosine

Class diagram extraction from textual requirements using Natural language processing (NLP) techniques Abstract The automation of class generation from natural language requirements is highly challenging. This paper proposes a method and a tool to facilitate requirements analysis process and class diagram extraction from textual requirements using natural language processing NLP and Domain Ontology techniques. Requirements engineers analyze requirements manually to come out with analysis

Discussion: Impure caffeine was extracted from the instant coffee by separation and evaporation. The amount of impure caffeine in 4.0045g of instant coffee was found to be 64.5mg with a yield of 1.6%. The yield is higher than the overall class average yield. This shows that there is a source of error. With the yield being higher‚ it is possible that the product did not have applicable time to dry and could still have been wet‚ which would make it heavier. Through a new technique called sublimation
