    were intradermally injected and the neutralized one was injected into the left side in the same manner and arrangement. The injected Guinea pigs were kept under observation for 48-72hrs. to demonstrate any dermal reaction. The results were interperitated by the degree of dermonecrotic reaction and its neutralization according to Sterne and Batty (1975) as…

    • 6 Pages

    The Krebs cycle consists of five major points . There is in firstly the general overwiew of cellular respiration and in secondly mitochondrie structure then Acetyl-Coa wich contains Production and possible fates then Krebs Cycle wich contains reactions and regulation and finally Glyoxylate cycle. For the general overwiew of cellular respiration we will talk about cellular respiration. Cellular respiration is an aerobic phase of catabolism in which organic fuel molecule are oxidi-zed to H2O and…

    Synthesis Of Aspirin Essay

    • 1003 Words
    • 5 Pages

    Aims: The objectives of this experiment are to carry out the process of synthesising aspirin and reinforce both the skills of recrystallisation and melting point determination. In this experiment, we are supposed to measure the amount of aspirin collected to calculate the percentage yield of aspirin. Apart from that, we are also required to find the melting point of aspirin. Introduction: 1.1: aspirin Aspirin, also known as acetylsalicylic acid, is an aromatic compound containing both a…

    Measurement of glutathione Glutathione (GSH) is a ubiquitous tripeptide which serves several vital functions including detoxifying electrophiles, scavenging free radicals and providing a reservoir for cysteine. The sulfhydryl group of GSH reduces 5-5'-dithiobis (2-nitrobenzoic acid) (DTNB) and form the yellow colour product 5-thio-2-nitrobenzoic acid (TNB)21. Measurement of the absorbance of TNB at 412 nm provides an accurate estimation of GSH in the sample. Figure 7. Materials 5×105 cells/mL…

    SYMMETRY WRITING EXERCISE PARAGRAPH I FePO4 is a type of -quartz, and when the temperature is relatively low, FePO4 still has the tetrahedral structure as seen in Figure 1. The Fe-O-P bridging angles are more similar between the FePO4 and -quartz. Change in the cell parameters become more significant between temperatures of 294K and 1073K, and it slowly acquires an octahedral structure as the temperature increases. When temperature reaches 980K, the compound transitions and the tilt angles…

    or a base. Thus, the reaction resulted in the production of a murky coloured liquid. If a full neutralization reaction was to completed, a product of a transparent solution should have been created. Sodium phosphate and potassium sodium tartrate are both not strong bases and that is why the average pH change was quite low. Both of them are not bases, however, they have a high pH. This is why they were both able to increase the pH on the acidic solution. A neutralization reaction did not occur,…

    NANOCARRIERS AS PROMISING NOVEL SYSTEMS FOR CONTROLLED DELIVERY OF DICLOFENAC SODIUM [N.B: Authors' details blinded by Pro Journals for Review] ABSTRACT The formulation and evaluation of Diclofenac sodium from liposomes, niosomes and nanoemulsion are analyzed. The release profiles of Diclofenac sodium were almost similar in all the formulations. It is found that 85% of Diclofenac sodium diffused out from the colloidal systems within 8hrs and practically all the drug was released within…

    Biopol Properties

    • 916 Words
    • 4 Pages

    Describe the Properties of Biopol Biopol is a copolymer made of the monomers PHV and PHB. PHB alone, with its short methyl side chain, is brittle and has very high crystallinity, meaning it cracks easily. Due to its high crystallinity and overall unsuitable properties for industrial use, PHV has been added to created PHBV, or Biopol. Biopol is semicrystalline, meaning it can still crystallize as well as melting at a lower temperature than PHB, making it industrially suitable. Due to its long…

    1. Identify the key technical characteristics of the Daguerreotype and Calotype processes. Illustrate your answer with examples of images form each technology, and say how they reflect its characteristics. (25%) Before the invention of the wet collodion process, which produces an unlimited number of copies of finely detailed images on paper and to print, by Frederick Scott Archer in 1851, there were two photograph processes previously: the daguerreotype and the calotype. The…

    The lab calculations resulted in an average of 21.7L/mol which was fairly close to the theoretical value, 22.4L/mol. In order to obtain that result through calculations, the water vapor pressure and the water height correction had to take place. After, the combined gas law had to be utilized and manipulated to find the volume and divide that volume by moles of magnesium. Being close to the theoretical value, 22.4L, it verifies that one mole of all gases occupy 22.4L in any container under…
