Copper vs. Fiber Modern telecommunication networks rely primarily on two types of cable. Older copper cables have been replaced in many cases by fiber optic "light pipes‚" first in undersea cables and major intercity trunks‚ and later directly to many homes and businesses. Principles Copper cables carry information as an electrical signal‚ which may be digital‚ as in phone lines‚ or analogue‚ as in audio speaker cable. In optical fibers‚ however‚ data is carried digitally by light from a laser

DENATURATION OF PROTEINS Abstract The experiment aimed to use the concept of viscosity to study the effects of different denaturants on 1% albumin extract. An Ostwald viscometer was used to measure the flow time of 5 mL of the blank and native protein. These were then denatured by adding 1 mL of denaturant and had their flow time measured. The flow time from the blank to denatured protein is increasing. The specific viscosity and reduced viscosity‚ ηred‚ were calculated

Abstract This experiment aimed to study the effect of various denaturants on albumin and casein protein extracts through viscosity measurements. 5 mL samples of native and denatured protein solutions were prepared‚ using -mercaptoethanol‚ urea and SDS as denaturants for albumin‚ and NaOH‚ NaCL‚ HCL‚ -mercaptoethanol‚ urea and SDS for casein. 5 mL blank solutions for each denaturant used were also prepared. The viscosity of the solutions were determined using Ostwald viscometer. ________

QUALITATIVE TESTS OF CARBOHYDRATES Final Lab Report Submitted by Brittany Fitzgerald 545301 Prepared for Nancy Cook Chemistry 3501 Monday November 26‚ 2012 RESULTS PART A: As a result of the Benedict’s test on various sugar solutions‚ it was found that galactose‚ mannose‚ arabinose‚ ribose‚ lactose‚ fructose‚ maltose‚ and cellobiose tested positively and therefore are considered reducing sugars. Glucose‚ starch‚ sucrose‚ and methyl-D-glucopyranoside on the other hand tested

A mental illness is any psychiatric disorder that causes untypical behaviour. Many people are unaware of the mental illnesses that affect adolescence. Mental illnesses can affect adolescences mood‚ thinking and behaviour‚ examples of the most common mental illness includes depression and anxiety. “Popular media tends to perpetuate the idea that the prevalence of mental disorders is increasing (McMartin‚ 2014)”. “About one half of adult mental health issues start before the mid-teens‚ and often treatment

Practical 3: Proteins Introduction: ‘Protein’ also an important food component‚ we commonly take in from our diet. In this experiment we have studied a certain property of protein‚ i.e.‚ protein can be denatured by various factors. A.

Police officers are trained in all situations not to use excessive force while using the use of force continuum; however‚ excessive force should be considered if the situation requires it. Excessive force is frequently used by police. Sometimes it is justified or excessive. Law enforcement officers are authorized to use force in any circumstances. Incidents involving excessive force by police frequently receive attention from the media‚ legislators and criminal courts (Use of force by police

Identifying sites of protein synthesis in Chlamydomonas using erythromycin and cyclohexamide as protein synthesis inhibitors. October 16‚ 2009 Introduction: In living cells‚ prokaryotic or eukaryotic‚ the synthesis (construction) of proteins is accomplished by similar machinery. Amino acids‚ ribosomes‚ messenger RNA (mRNA)‚ and transfer RNA (tRNA)‚ are all necessary for the building of functional proteins in a cell. Ribosomes are the site of protein synthesis in a cell‚ and there are two
