We examine factors controlling the photochemical oxidation of SO2 in tropospheric aerosols using a gas-aqueous photochemical model. Over a range of liquid water contents (3x10 -4g H20 m -3 to 9 g H20 m -3) and pH values (0 to 8), we find that H202(aq) and O3(aq) provide the major sinks for SO2 in the aqueous phase when pH is held constant at below 5 and larger than 6, respectively. OH(aq) may b...

s: Soda-anthraquinone (soda-AQ) alkaline sulfiteanthraquinone (AS-AQ) and ASAM (alkaline sulfiteanthraquinonemethanol) cooking of southern cattail whole stem and bark from Sudan was carried out under different conditions and pulps with acceptable to good screened yields and very good mechanical properties were attained. The southern cattail whole stems gave satisfactory mechanical properties wi...

The Extreme Male Brain (EMB) theory posits that autistic traits are linked to excessive exposure to testosterone in utero. While findings from a number of studies are consistent with this theory, other studies have produced contradictory results. For example, some findings suggest that rather than being linked to hypermasculinization for males, or defeminization for females, elevated levels of ...

The 4-anilinoquinazoline (4-AQ) derivative gefitinib (Iressa) is an oral epidermal growth factor receptor tyrosine kinase inhibitor. Oral administration of 4-AQ molecules, such as gefitinib, inhibits ATP-binding cassette (ABC) transporter-mediated drug efflux and strongly increases the apparent bioavailability of coadministered drug molecules that are transporter substrates. Based on in vitro s...

Let V ∼= Fq be a v-dimensional vector space over the finite field Fq with q elements. By [ V k ] we denote the set of all k-dimensional subspaces in V . Its size is given by the q-binomial coefficient [ v k ]q = ∏k−1 i=0 qv−qi qk−qi for 0 ≤ k ≤ v and 0 otherwise. The set of all subspaces of V forms a metric space associated with the so-called subspace distance dS(U,W ) = dim(U + W ) − dim(U ∩ W...

Background: This study investigated the prevalence of antimalarial drug resistance markers in P. falciparum isolates, involving the detection of mutations at the mdr1-86, which associates with amodiaquine resistance, and dhfr mutations associated with SP resistances. Methods: The dot-blot/probe hybridization was used to determine multidrug resistance (mdr1-86) and assess the correlation of Amod...

(1.1) f(aq + b) = f(aq) + f(b) or f(aq + b) = f(aq)f(b) for all r ≥ 0, a ≥ 0 and 0 ≤ b < q. Note that these equations force f(0) = 0 or f(0) = 1 respectively. These functions are called q-additive and q-multiplicative, respectively. It is easy to see that the functional equations imply that these functions are defined for all integers, when the values f(aq) are known for 1 ≤ a ≤ q − 1 and all r...

Abstract. In liquid cloud droplets, superoxide anion (O2(aq)-) is known to quickly consume ozone (O3(aq)), which relatively insoluble. The significance of this reaction as a tropospheric O3 sink sensitive the abundance O2(aq)- and therefore production its main precursor, hydroperoxyl radical (HO2(aq)). aqueous-phase oxidation oxygenated volatile organic compounds (OVOCs) major source HO2(aq) in...
