He mentioned the effect of the dominant languages‚ that controls communications and commerce‚ on the small one that do not have any defense mechanism‚ like television or currency‚ to protect its existence. Because of that the people of Tuva must speak Russian or Chinese if they want to stay in contact with the outside world. The writer then mentioned another endangered languages known as

IRONING BOARD A. Introduction 1. What is an Ironing Board An ironing board is mainly a large‚ flat piece of board or metal‚ typically with legs and usually covered with a heat-safe padding on which clothing or linens may be ironed. The legs of an ironing board can be adjusted for height. 2. Basic Description of an Ironing Board A standard ironing board is long and skinny‚ about 15” wide and 4 1/2’ long‚ has two basic parts which include a flat board for ironing and folding legs

My Reaction to Apollo 13 The movie Apollo13 is great but little kind of boring. Tom Hanks is a great artist! He is my idol. One of his great movie is Forrest Gump. By the way‚ The Apollo13 is America’s third moon landing mission. En route‚ an onboard explosion deprives their spacecraft of most of its oxygen supply and electric power‚ forcing NASA’s flight controllers to abort the Moon landing‚ and turning the mission into a struggle to get the three men home safely. I thought Jim’s wife was his

ENGINEERING Reaction Engineering CGC035 / CGC052 Problem Sheet 3 - Fluid-fluid reactions 1. The reaction rate for the heterogeneous reaction A(g) + B(l)→ products is second order according to the expression -rA=kCACB and it is relatively slow compared to mass transfer so it takes place in the bulk of the liquid. Combine the following rate expressions for diffusion through the gas and liquid films‚ -rA=kAga(pA-pAi) and -rA=kAlaCAi-CA‚ with Henry’s law pAi=HACAi and the reaction rate

In the first step‚ 2’-OH proton of the ribonuclease sugar undergoes deprotonation by the basic imidazole ring of His12. This produces a 2’-O-‚ which subsequently acts as a nucleophile for attack towards the phosphorus atom of the phosphate group bonded to the 3’-C end of the same ribonuclease sugar. During this process‚ it causes His12 to become protonated‚ thus causing it to become acidic. 21-22 Conversely‚ His119 acts as an acid to facilitate the departure of the leaving 3’-monophosphate group

Neural and Hormonal Mechanisms in Aggression Aggression in humans has been associated with low levels of serotonin and high levels of dopamine. Usually‚ serotonin has a calming effect‚ which inhibits aggression. When serotonin levels are low‚ this inhibitory effect is removed and people are less able to control their aggressive behaviour. Evidence for the importance of serotonin comes from two main sources. Brown (1982) found that there were low levels of the waste products of serotonin in the

Reactions in Aqueous Solutions: Metathesis Reactions and Net Ionic Equations Introduction: Metathesis or double decomposition reactions are a reaction in which two compounds react to form two new compounds‚ with no changes in oxidation number. The ions of two compounds exchange partners. AX + BY AY + BX This reaction can occur between two inorganic salts when one product is insoluble in water‚ driving the reaction forward. A typical example is as followed and is considered a molecular equation
