The climate of Canada is governed by a number of elements of climate which lead to a regional variety of weather patterns in the country. These weather patterns are pertinent in determining the type of climate which each particular region experiences. Climate has many impacts on a country’s ecosystem, sociology and economy, and is therefore a key component in the overall health of any economy. Disruptions to climate can have enduring outcomes for Canada and its people. This paper attempts to discuss the current climactic patterns which occur in Canada, and outlines some ways in which climate change ...

When water is added to lead chloride, the solute sparingly dissolves with some undisclosed particles settling at the bottom of the beaker. Lead chloride is only sparingly soluble in water. When the dilute hydrochloric acid is added to the saturated solution of lead chloride, a white precipitate is formed. This is because of the common ion effect where the excess chloride ions from HCL cause lead chloride to precipitate.

Objective
Purpose of this laboratory is to inspect the effect of precipitation hardening in Aluminum and steel alloys.
Theory
Hardness is a property of a material which delineates resistance to permanent or plastic deformation. For metals, hardness is generally defined as the resistance to indentation. One way to attain hardness is to look into the effect of precipitation hardening. This type of hardening helps to detain the yield strength in the material. There are four methods used to test hardness of a material: Rockwell, Brinell, Vickers, and Knoop. The Rockwell hardness test measures the depth of indentation, while the other three ...
INTRODUCTION
Baghouse filters are fabric filter units consisting of one or more isolated sections containing an array of fabric bags (Vatavuk, 1998). Shapes of these bags range from round, flat, tube-shaped, to pleated cartridges. In theory, gas containing high particulate matter level passes through the fabric bag surface. The particulate matter is retained while the cleaned gas is either recycled to the process or vented off the exhaust. This paper attempts to discuss the different concepts behind baghouse filters in relation to environmental engineering. Specifically, this paper discusses (a) particle pollution, (b) baghouse filter principle, (c) filter media selection, (d) types of ...

“Probable Causes of the Abnormal Ridge Accompanying the 2013-2014 California Drought: ENSO Precursor and Anthropogenic Warming Footprint” by S.-Y. Wang, L. Hipps, R. R. Gillies, and Jin-Ho Yoon, AGU Publications: 3220 – 3226, 2014
CE481 or CE581
Abstract
The paper analyses the causes of the California drought in 2011/12 and 2013/14 winter seasons. There were ensemble simulations and observations used for indicating the main forces that led to dry winters. Usually, they are associated with ridge off the west coast. SST forcing can be useful for explanation of one third of California winter precipitation variance. ENSO is another model that may explain ...
Analysis of Hydrated Copper Sulphate
The above experiment was conducted to determine the amount of Copper and water present in the given sample of hydrated Copper (II) Sulphate.
Introduction
Gravimetric analysis used in this experiment refers to a set of techniques in analytical chemistry aimed at the quantitative determination of an analyte based on the mass of a given solid. In most gravimetric methods the analyte, in this case hydrated Copper Sulphate, is first converted to solid by precipitation with an appropriate reagent, Oxine in this case. The solid precipitate is then collected by filtration (precipitation). The lab scientist washes the precipitate since it is insoluble in ...
Chapter 3: Introduction to the Atmosphere
This chapter is a basic introduction to the several properties of the atmosphere. Air is the main composition of the atmosphere and contains the majority of Nitrogen gas for 78% and Oxygen gas for 21%. The rest comprises of other gases. Although the atmospheric mixture also constitutes particulates such as dust, smoke, pollens, ash and other industrial emission. The atmosphere can be divided into homosphere and heterosphere. Different gases are scattered uniformly throughout this layer, unlike the composition in the heterosphere where each gas is separated in each layer. Located on the topmost part of the atmosphere is where the ...
Report on Arsenic-Free Water Filters
Introduction
Arsenic concentration in water varies depending on the source. This report is based on the discussion of the measures of reducing the levels of arsenic in the tube-well water. In this case, three criterions are selected for the study. Each of the methods chosen will enumerate its merits and demerits that suit the application.
Problem
Arsenic is semi-metal element found in the periodic table. It is an odorless, tasteless element that occurs naturally in water, rocks and soils, air, plants and animals.
Arsenic poisoning from various water sources such as well present a significant problem across the globe. The ...
Aluminium is produced from bauxite. Al2O3. This is referred to as Alumina, or aluminium oxide is extracted from the ore. After the extraction, electrolytic reduction process is used to transform Alumina to Aluminium. From every two tonnes of alumina, one tonne of aluminium is produced. The bauxite consists of ferrous oxide, titanium oxide, earth silicon, and alumina, approximately 40 to 60%. Bayer process is used to separate pure aluminium from bauxite (Habashi 16). This process involves heating the ore in an autoclave that contains caustic soda. Cooling then takes place, in order to separate the solid residue that is ...
Abstract
This study aims at examining different methods used to study the composition and variation of marine organisms and plants. Various methods create different results that show the effect of the geological environment structure in the ecosystem at various oceanic conditions. Temperature variation is used as a major determinant of the population distribution of the organisms and plants found in various ecosystems. For instance, this study will use crocodilian fossils and mangroves to assess the composition of ancient oceanic environments and the trend of the climate and geological change in these conditions (Häder 1999).
This study uses some isotopic ...
Abstract
The central dogma of biology is performed within this study. A vector of T7 RNA Polymerase gene was inserted into E.Coli where it could be transcribed into RNA and subsequently translated into protein. The protein was extracted and purified. A successful clone was produced by inserting the vector into the expressing cell line and it was observed after achieved an optical density at 600 nm (OD600) of 0.84. A collected 20.87 ug of double stranded RNA was found. Additionally, a linear DNA template OD260: 0.04 µg/ml was transcribed. After expressing it was found that a total protein concentration of ...
Gravimetric analysis
Introduction
Gravimetric analysis is a method of measuring of mass of chemical substances. This analysis can be classified in two types; precipitation and volatilization (Bassett et al.). In precipitation method some steps, involved to determine quantify of the chemical substances, are separation of an ion in aqueous solution by a reaction, filtering and washing the precipitate, converting the precipitate to a substance of known composition, and lastlytaking weight of the precipitate as well asevaluating its mass. The chemical substance must be precipitated fully.Theunknown amount of original ion can be evaluated from the mass and known composition of the precipitate. Gravimetric method ...
