(as in hypothyroidism anddiabetesmellitus), or severe emotional trauma. Immunological reactions, in which maternal antibodies mistake the fetus for foreign tissue, have been implicated in recurrent, or habitual spontaneous abortions. It is estimated that at least 20% of all pregnancies end in ...
In a first-order reaction, the rate of the reaction is determined by the concentration of one reactant. As such, there may be other reactants present in the chemical equation, but their order or exponent is equal to zero. First-order reactions are also called unimolecular reactions. An exa...
Cardioversion time was significantly shorter than amiodarone, the incidence of cardiovascular adverse reactions was significantly higher with ibutilide than with amiodarone [11]. In the literature, ibutilide has been reported to have a conversion rate of 30 to 50% for atrial fibrillation and up to...
The poor air quality increases the risk of chemical reactions in the pigments of the murals and greatly affects the quality of visitors’ experiences [4,5,6]. In particular, an increase in the CO2 concentration inside the caves would cause the murals to face an acidic environment, posing a ...
Chemical reactions are reversible; and once the product starts to accumulate, the backward reaction starts. Consider the decomposition of nitrogen dioxide, {eq}2NO_2 \longrightarrow 2NO + O_2 {/eq}. When the reaction begins and in the very moments of this process, the amounts of nitrogen...
Genes make enzymes, and enzymes control the rates of chemical processes. Genes do not make ‘novelty seeking’ or any other complex and overt behavior. Predisposition via a long chain of complex chemical reactions, mediated through a more complex series of life’s circumstances, does not equal ...
Measuring enthalpy of reaction. To determine the initial rate of reactions using the IrCal approach the precise Δ H of reactions should be known. The Δ H (kCal/mol) of each reaction was calculated from the area under the complete power curved measured by ITC for conversion of a ...
Reactions were grade 1 consisting of mild mucosal inflammatory response with a partial whitish circumferential membrane in an asymptomatic patient; grade 2, thicker complete white circumferential membrane with cough and/or obstructive problems requiring intervention; grade 3, severe inflammatory response with...

a first-order reaction can be defined as a chemical reaction for which the reaction rate is entirely dependent on the concentration of only one reactant. in such reactions, if the concentration of the first-order reactant is doubled, then the reaction rate is also doubled. similarly, if ...
