For the past several decades, ninhydrin has been used in the development of fingerprints from surfaces. The fingerprints revealed by ninhydrin have been used to compare against other known fingerprints, whether from the person of interest or a database, which can lead to a match on a victim or a suspect on a case. But what about the fingerprints that do not have a match in a database? Can that print be of any use to forensic scientists? In the journal article, “New Horizons for Ninhydrin: Colorimetric

An Introduction to Qualitative Analysis Purpose:  Tests the ions of Mg2+, Ca2+, Sr2+, and Ba2+,  and identify them separately. By using these  observations, identify the unknown ion. Then tests  the ions of SO42-, CO32-, Cl-, and I-,identify them separately, and use the observation to identify the unknown.  Procedure Part I - Qualitative Analysis of Group 2 Elements  Mix 0.02M K2CrO4 with each Mg(NO3)2, Ca(NO3)2, Sr(NO3)2 and  Ba(NO3)2 together. Secondly, mix 0.1M (NH4)2C2O4 instead

During part A of the experiment, the solution and LabQuest was prepared. The 300 ML solution of HCL solution was prepared through the addition of 200 ML of deionized water and 100 ML of 6 M HCL. This solution was labeled “2 M HCL”. The solution was stirred with a glass stirring rod. Next, a 150 ML of 3 M NaOH was prepared through the addition of 50 ML of deionized water and 100 ML OF 3 m NaOH solution. This was labelled “2 M NaOH”. The solution was stirred with a glass stirring rod. It was important

Purpose: The purpose of this lab is to determine both the formula and percent water of hydrated magnesium sulfate. Background: According to George B. Kauffman of Britannica, a hydrate is “any compound containing water in the form of H2O molecules, usually, but not always, with a definite content of water by weight.” Within this, there are two aspects of the compound; the “water of hydration” and the anhydrous salt. When a hydrate is heated, the “water of hydration” leaves the compound as vapor

improved sealing of all containment areas • Modification of the Odour Control Unit (OCU) to duty/assist i.e. both air scrubbers could work simultaneously when required • Modification to the OCU for the dryers to cater for increased load and addition of ammonia scrubber. • Containment of the collection culverts from the lamellae tanks and provision of 2 no. Bord na Mona Bio-filters to treat the extracted air from these sources. • Addition of containment screens and improved extraction rates from the sludge

breakdown of suspended particulate carbonaceous matter. III. Oxygen demand by oxidation of ammonia to nitrate by nitrifying bacteria present in the effluent sample. After undergoing biological treatment in the secondary reactor, residual soluble carbonaceous BOD matter present in the effluent reduces in concentration to below 15 mg/L. Subsequently, nitrifying bacteria populations tend to grow rapidly feeding on ammonia which is present in the partially treated sewage. Nitrification may not be complete at

In this lab, students observed reactions, or lack thereof, between metals Mg, Cu, Zn, and Fe; when placed in solutions of Hydrochloric acid (HCl), Cu(NO3)2, Zn(NO3)2, Fe(NO3)3 and Mg(NO3)2. Students were tasked with observing whatever reaction took place and recording the characteristics of said reaction. To set up the lab, students placed a piece of each metal in a pocket on a spot plate. The plates had four pockets in a row, one for each metal, and 3 rows of pockets. Students would then put a solution

Normal Gene Function eNOS is an enzyme. The function of eNOS is to produce low concentrations of NO which helps endothelial function. NO has a direct role in preserving the role of endothelial junctions NO production reduces chances of Diabetes. No is a proven relaxer in the human body including vascular relaxation. What makes eNOS stand out from other NOS genes is that it is calcium dependent. Polymorphism eNOS is what is known as a polymorphism Genetic polymorphism is a common mutation due to
