SaskWater has received a Request for Service from the Town of Birch Hills requesting a peak flow of 130 igpm. An assessment was performed includes two of SaskWater existing systems. Option #1 the Melfort Regional Treated System (CLPOWSS); three scenarios were considered while investigating the CLPOWSS. Scenario #1 connects the Birch Hills community with the CLPOWSS, plus twining 5.5 km of the existing pipeline between Melfort and Kinistino, which would allow for 100% of average daily…

Many chemicals are safe to handle but negatively impact the environment in the long run. Other chemicals such as arsenic are toxic even in the smallest amounts. Mercury is a natural element that occurs throughout our environment and solar system. It has unique properties (i.e liquid metal at room temperature) and can be found in very small concentrations in many rocks and is the main component of the mineral cinnabar. Natural background levels can be detected in soils, living organisms, air, and…

Three at one stroke: A small phosphorus compound could have been the crucial prerequisite for first life on Earth, because this chemical was able to synthesize three major biomolecules: Nucleotides as precursors of RNA and DNA, Peptides as protein precursors and Lipids for the envelope membranes of the first cells. Thus, the molecule called Phosphorodiamidate was possibly the key to the development of the first cells. primevalsoup.jpg A molecule could have helped in the formation of three…

For a long time now people have known that atoms make up everything in the universe. From the air, to the people, to the houses, planets, stars - everything is made up of the tiny building blocks. Atoms are made up of even tinier particles called electrons, protons, and neutrons. The electrons spin wildly around the center of the atom where the nucleus is found. The nucleus is made up of protons and neutrons that are bound together into a tight ball. Many pictures you see of a nucleus exaggerate…

Iodine is Element 53 on the periodic table and is a halogen. Iodine is a violet-black non-metal. Iodine has only 7 valence electrons and is the less reactive than the elements above it in the halogen family. Even though it is less reactive, it still forms many compounds with many different elements. Iodine was first discovered by Bernard Courtois in 1811. There is one stable isotope 127I and fourteen radioactive isotopes 122I through 126I and 128I through 136I (Iodine). Iodine is widely…

Technetium There are quite a few elements on the periodic table, but some are more special than others. For instance, Technetium, is special because it is the first radioactive element. Since it was the first radioactive element, it is known to be one of the most interesting on the periodic table. Technetium is a silver like metal that will tarnish in moist air slowly. Nitric acid, aqua regia, and conc. sulfuric acid will dissolve this metal, though it will not dissolve in hydrochloric…

Valuable, colorful, and enriched with a unique history are three phrases that describe many things. However, all three combined only seem to describe Birthstones. Birthstones are amazing objects that affect our economy in many ways. More importantly, birthstones have a deep connection to chemistry and science. Due to their chemical properties, birthstones can also be used for medicinal purposes and healing techniques that have helped humans throughout time. Overall, birthstones contain many…

Since as early as 500 B.C. philosophers have been concerned with the examining the composition of the universe. The early Greek philosopher, Thales, argued that the world was made up of one universal thing; water. It wasn’t until Democritus and the Atomist until philosophers began to rationalize about small particles called atoms as the things that make up the universe. As time approached the 18th century, advances in the scientific method gave rise to developing processes to examine the…

– equation (2 gives info on location of electron in terms of probability density - wave functions are called orbitals – [pic], where E is energy, e2 is electric potential, r is orbital radius and h is Planck’s constant 1925 Wolfgang Pauli – each orbital has only 2 electrons is now explained due to direction of spin of electrons. Spinning electrons create magnetic field. Only 2 electrons of opposite spin in an orbital referred to as Pauli exclusion principle Hund’s rule – half fill…

proximity of Carthage’s production to Shakespeare’s original text. This essay will begin with a detailed description of the College of Lake County’s production of Shakespeare’s The Tempest with the goal of evaluating the traditional and nontraditional elements of the show. Subsequently, the similarities and differences between CLC’s the Tempest and Carthage’s the Breathe of Stars will be considered in order to generate…
