al‚ 2014). Lesions‚ pharmacological inhibition‚ long-term potentiation (LTP) saturation‚ the act of learning itself within the hippocampus can result in impaired spatial learning and memory (Whitlock et al‚ 2006 and Suh et al 2011). Morris water maze test was developed by Richard G. Morris in 1981 for testing of hippocampal dependent memory including acquisition of spatial memory and long-term spatial memory (Morris‚ 1981). It is one of the main models used in the validation of neurocognitive

Can you imagine getting lead poisoning from drinking what you may think is clean‚ filtered water? Well‚ that is exactly what is going on in Flint. The amount of lead found in this water is harming children and adults. Even the color doesn’t seem look right‚ I mean‚ why is this water brown? And why does it smell and taste awful? The Flint Michigan water crisis has gotten out of control and has been for the past couple of years. In class‚ we were showed a mini documentary on how bad this situation

How do we chemically show that milk is off? Background investigation The problem that my associate Keely and I wanted to analise was how to chemically test and show that milk is off and how this happens. We wanted to know this because we have just purchased a small dairy farm on the outskirts of Camperdown Victoria. We are curious about the science behind off milk‚ and are wondering if there are ways our milk stay fresher for longer. Aim The main focus of our experiment was to find

Photocatalytic degradation of methylene blue using TiO2 nanoparticles Nupur Mittal Chemical Engineering‚ IIT (BHU) Varanasi. Abstract: The aim of this research is to reduce the pollution caused by methylene blue dye in waste water coming from textile industries. For this purpose‚ TiO2 nanoparticles are made as they show good photocatalytic activity in degradation of dyes into harmless products. Synthesis is done using titanium butoxide and 2-propanol. The particles formed were a little larger

Alloy - An alloy is a substance made by melting two or more elements together‚ at least one of them a metal. An Example: Examples of alloys include brass‚ bronze‚ 14k gold‚ and sterling silver. covalent bond - A covalent bond is a chemical link between two atoms in which electrons are shared between them. An Example: There is covalent between the oxygen and each hydrogen in (H 2 O). Each of the bonds contains two electrons - one from a hydrogen atom and one from the oxygen atom. Both atoms

The Formula of Lead (II) Iodide The Analysis of a Chemical Reaction Introduction This experiment is based upon a discovery made through the isolation of PbI2 using a particular scientific method‚ which studies ratios of lead to iodine. Precipitation reactions occur when oppositely charged ions attract and form an insoluble ionic solid. This experiment examines the precipitation reaction between lead (II) nitrate‚ Pb(NO3)2‚ and potassium iodide‚ KI. Both are dissolved in water and the reaction

Lead and The Environment Some materials are so commonplace that we take them for granted. One of those materials is a grayish metal that has been with us for thousands of years. That metal is lead‚ still one of the world’s most useful substances‚ and one that never ceases to find a role in human society. Lead has the atomic symbol of Pb (for plumbum‚ lead in Latin). The atomic number for lead is 82 and the atomic mass is 207.19 AMU. It melts at about 327.502 oC and boils at 1740 oC. Lead

a leader‚ someone who takes every thought‚ concern‚ hope‚ and anguish of those beneath him and acts appropriately. A leader means to be someone who lives not for them self but for others and whole heartedly enjoys every single moment of it. To lead is like riding towards the beating war drums of an approaching army. All will hear it: some will flee like cowards after every thump‚ some will pretend like the beats were never uttered‚ but others will answer the call valiantly with a quickness in

Task 3: The chemical tests used in order to carry out and collect these results are useful for the simple identification of colourless organic liquids and ones that are often found at the scenes of crime. The first test carried out was the Lucas test which was used to identify a variety of alcohols following the contribution of a given solution‚ from carrying this out I could then identify that primary and secondary alcohols were present with one tertiary alcohol also being present however despite
