between conflict and resolution in three short stories in The Heinemann Book of African Women 's Writing, first "Mother was a Great Man," by Catherine Obianuju Acholonu second, "The Pay-Packet," by Ifeoma Okoye and finally, "Saltless Ash" by Zaynab Alkali. All three of these short stories are written by women of Western Africa and all three of them share similarities and differences regarding the nature of the conflict as well as the resolution. In "Mother was a Great Man," the main character,…

An electrolyte is an ionised component of a living cell, blood or any other matter and can conduct electricity when molten or dissolved. There are many different electrolytes found in our body such as sodium, potassium, chloride, calcium and so forth. Electrolytes have many functions throughout the body for instance controlling the water balance in the body. Also assisting transmitting nerve impulses and helping your muscles relax and contract. For example Sodium chloride which is also know by…

The availability of the crystal structure of the potassium dependent asparaginase from Phaseolus vulgaris (PvAspG1) provided insight into the mechanism of potassium activation (Bejger et al., 2014). There are two alkali metal binding sites in each α subunit, located in highly characteristic metal coordination loops. One of them is structural and is referred to as the stabilization loop. It is also present, as a sodium binding loop, in the crystal structure of K+ independent asparaginase from…

ingredients and the 5th item listed is “Cocoa processed with Alkali”(Cocoa Puffs). Alkali is a chemical compound that neutralizes or effervesces with acids and turns litmus blue. This in other words this means Cocoa is “washed in a potassium carbonate solution that neutralizes the cocoa’s acidity to 7”(Velie). What the Velie means by having the acidity to 7, the acidity is based off the ph scale 1-6 being an acidic item 8-14 being alkalis and 7 being neutral. Based off of this we can see that…

A different type of Japanese bamboo had been studied by Phong et al. (2012). Moso bamboo was harvested and processed using several methods to obtain the fiber. In alkali extraction method, the bamboo was cut into thin slabs with length and thickness of 25 cm and 3 mm, respectively. The slabs were immersed in different concentration NaOH solution (1%, 2%, 3%) at 70 ⁰C for 10 h. This study showed that only 1% NaOH resulted in higher mechanical properties. The roller looser was then used to produce…

observing the characteristics of the three elements from group 1, Lithium, Sodium, and Potassium, we can see that they all share the appearance of being lustrous and metallic, with a silvery-white presentation, and it is also known that they are all alkali metals. It is also noticed that they are all soft metals easily cut with a knife rather than most metals such as calcium or iron. All three elements are stored within oil, with Sodium as an exception being stored in kerosene, as an attempt to…

Trans-Pecos Province Magma Types Nathanial Matis 01/12/2014 Trans-Pecos Province Magma Types Nathanial Matis Abstract The Cretaceous was the starting point when the Laramide Orogeny began to fault and fold as a result of tectonic activity which pushed the Farallon plate into the North American plate forcing the subduction of the Farallon. This subduction caused the plate to melt and form magma that either formed laccoliths, or intruded country rock with different igneous compositions. These…

Biodiesel is an alternative diesel fuel for diesel engines that is made from renewable biological sources like vegetable oils, animal fats, and microalgae. Since its main feedstock is a vegetable oil or animal fat, biodiesel is generally considered to be renewable. There are four primary ways known to make biodiesel – (1) direct use and blending, (2) microemulsions, (3) thermal cracking and (4) transesterification. Although the main use is the transesterification of vegetable oils and animal…

Chemistry ERT - ITEM 3 Item 3.1 and 3.2 – Graphs The trend for the number of electrons in the valence shell for an element is clearly seen in this graph. The lowest point of each peak coincides with the Group I alkali metals. From there on, the electron count climbs until a full shell is reached at eight electrons, i.e. the noble gases who have full outer shells. The full shell signals the end of a Period at Group VIII, and then it begins again in Group I in a new Period. There is…

Ion is a group of atoms which they behave on an electrical charge; there are two types of ions; cation and anion. Cation is a positively charged ion whereas Anion is a negatively charged ion. First ionisation energy- The first ionisation energy is the energy to remove electrons that are unstable from 1 mole of gaseous atoms to gain 1 mole of gaseous ions with a positively charge (1+) As you go down a group, the energy decreases from the top to the bottom due to the shielding effect. When there…
