The method combines the reactions of copper ions with the peptide bonds under alkaline conditions (the Biuret test) with the oxidation of aromatic protein residues. The Lowry method is best used with protein concentrations of 0.01–1.0 mg/mL and is based on the reaction of Cu+‚ produced by the oxidation of peptide bonds‚ with Folin–Ciocalteu reagent (a

Buttonhole technique was initially used in Europe with people who had restricted cannulation sites. In this technique‚ the needle is implanted accurately at the same site and the same angle for every dialysis session. (Twardowski & Kubara‚ 1979). Formerly cannulation is mandatory with sharp needles to create a track formation. Ideally‚ the same person must cannulate the fistula to create

Scientific Method The Scientific Method is a system devised to allow scientists to gain insight‚ or knowledge‚ on a wide range of questions about one’s behavior and other points of interest. The first step in this process is to identify a question that deserves an explanation or answer to. For example‚ a good indentifying question that one could use would be why did the chicken cross the road? This is a specific behavior that can be addressed and quantified. Once the individual has the question

Introduction In order to identify new materials‚ scientists use a variety of chemical and physical methods to determine molecular masses. One of these methods includes the Dumas method for determining the molecular weight of a volatile liquid. This method‚ which was proposed by John Dumas in 1826‚ makes use of a volatile liquid (vaporizes at a relatively low temperature) and allows this liquid to be heated in a water bath to a known temperature and escape from a flask through a tiny opening (Giunta

Inquiry Method Steps 1. Ask a question or identify the problem – What do you want to learn about? This question forms the starting point for inquiry. Example: You may be interested in discovering what methods of studying lead to better exam results. 2. Develop a hypothesis – A hypothesis is possible answer to your research question. Your hypothesis gives you direction. It helps you to determine what needs to be tested and which research method you will use. Example: You may hypothesize that

external ways that I could recruit for the job in my final assignment is through the internet‚ private employment‚ newspaper advertisement‚ and employee job board(hiring within company). The internet recruiting methods are the most common method used today‚ and the many advantages consist of lower costs‚ time saving‚ and extra information about each applicant.
