The photoelectrochemical behaviour of the multilayer semiconductive electrode(GaAs/AlxGa1-xAs)with the structure of n+nP and n+nPP was studied in na2SO4 solution. Compared with single kind semiconductor electrode, the commposite one has broader photoresponse spectral region and larger open-circuit photovoltage,consequently gives higher solar energy conversion efficiency.

This paper addressed the efect of copper acetate on the combustion characteristics of anthracite depending on the fractional composition of fuel and additive introduction *** was impregnated with 5 wt%of Cu(CH_(3)COO)_(2)by mechanical mixing and incipient wetness *** anthracite samples of diferent fraction with dnd d=1.0-2.0 mm were *** to EDX mapping,incipient wetness impregnation provides a higher dispersion of the additive and its uniform distribution in the *** ignition and combustion characteristics of the modifed anthracite samples were studied by thermal analysis and high-speed video recording of the processes in a combustion chamber(at heating medium temperature of 800℃).It was found that copper acetate increases anthracite reactivity,which was evidenced by decreased onset temperature of combustion(ΔT_(i))by 35-190℃and reduced ignition delay time(Δτ_(i))by 2.1-5.4 *** acetate reduces fuel underburning(on average by 70%)in the ash residue of anthracite and decreases the amount of CO and nO_(x)in gas-phase products(on average by 18.5%and 20.8%,respectively).The mechanism for activation of anthracite combustion by copper acetate is proposed.

Background Integrated positron emission tomography and computed tomography （PET/CT） is increasingly used for the preoperative nodal staging of non-smail cell lung cancer （nSCLC）.The aim of this study was to evaluate the accuracy of PET/CT in comparison with CT in detection of nodal metastasis and preoperative nodal staging in patients with nSCLC,and to analyze the causes of the PET/CT false-negative and false-positive *** Consecutive patients with pathologically proven nSCLC who underwent staging using PET/CT from July 2008 to February 2012 were evaluated *** staging was pathologically confirmed on tissue specimens obtained at *** accuracy of PET/CT and CT in the assessment of intrathoracic nodal involvement was determined using histological results as the reference *** regression was used to define the causes of the false-negative and false-positive *** A total of 528 lymph node stations were evaluated in 101 *** nodes were positive for malignancy in 43 out of 101 patients （42.6%）,and 101 out of 528 nodal stations （19.2%）.PET/CT was significantly more accurate for nodal staging than *** sensitivity,specificity,positive and negative predictive values,and accuracy of PET/CT for detecting nodal metastasis were 51.5%,95.8%,74.3%,89.3%,and 87.3% and the corresponding data by CT were 45.5%,87.1%,45.5%,87.1%,and 79.2%,***/CT confers significantly higher specificity,positive predictive value,and accuracy than CT in detecting nodal ***-negative results by PET/CT are significantly associated with smaller lymph node size,whereas false-positive results are related to a combination of inflammatory disorders and larger lymph node *** PET/CT confers significantly higher accuracy than CT in nodal staging,and is more specific and accurate than CT in detecting nodal metastasis but has a low sensitivity and high false-negative rate.

The increasing demand in the diverse device applications of transparent conducting oxides （TCOs） requires synthesis of new TCOs of n- or p-type conductivity. This article is about materials engineering of ZnO-SnO2- In2O3-Ga2O3 to synthesize powders of the quaternary compound Zn2-xSn1-xlnxGaxO4-δ in the stoichiometry of x = 0.2, 0.3, and 0.4 by solid state reaction at 1275℃. Lattice parameters were determined by X-ray diffraction （XRD） technique and solubility of In3＋ and Ga3＋ in spinel Zn2SnO4 was found at 1275℃. The solubility limit of In3＋ and Ga3＋ in Zn2SnO4 is found at below x = 0.4. The optical transmittance approximated by the UV-Vis reflectance spectra showed excellent characteristics while optical band gap was consistent across 3.2 eV with slight decrease along increasing x value. Carrier mobility of the species was considerably higher than the older versions of zinc stannate spinel co-substitutions whereas the carrier concentrations were moderate.

Associations of null polymorphism (copy number variation) of detoxification genes GSTM1, GSTT1 and GSTP1 (at rs2495636, 105 Ile/Val) with the breast cancer (BC) were assessed in two main ethnic groups of the Republic of Kazakhstan (Kazakhs and Russians). Total number of patients was 181, and of controls 397. Statistically significant difference was observed between BC patients and healthy individuals in alleles frequency (χ2 = 4.89, р = 0.007) of GSTP1 gene at rs2495636 (105 Ile/Val) among the Kazakhs ethnic group. Difference in genotypes distribution (χ2 =5.26, р = 0.076) at this site is approximating to be statistically significant. In the Russian group, no differences were found in genotypes and alleles atrs 2495636 of GSTP1 gene between cases and controls. There was no significant difference between null polymorphism (copy number variation) of GSTM1 and GSTT1 genes among cases and controls in both ethnic groups.

Associations of polymorphisms in rs4646903 site of CYP1A1 and rs1056836 site of CYP1B1 genes with the breast cancer (BC) were studied in two main ethnic groups of Kazakhstan Republic (Kazakhs and Russians). Total number of BC patients was 181, controls—397. The statistically significant differences were revealed in allele frequencies (χ2 = 5.93, р = 0.004) and in genotypes distribution (χ2 = 8.71, р = 0.015) in rs4646903 site of CYP1A1 gene in Kazakh but not in Russian group. The study of CYP1В1 rs1056836 site demonstrated differences in genotype distributions (χ2 = 7.48, р = 0.023) between BC patients and controls in Russian but not in Kazakh ethnic group.
