Towards large-area perovskite solar cells: the influence of compact and mesoporous TiO2 electron transport layers

Titaniumdioxide (TiO2) is a widely used electron transportmaterial in organic-inorganic hybrid perovskite solar cells (PSCs). In order to reveal the influence of an additionalmesoporous TiO2 (mp-TiO2) layer on fabricating large-area perovskite solar cells using TiO2 as the electron transport layer, we have conducted a comprehensive study on the solution-processed PSCswith orwithout an additionalmp-TiO2 layer. Photoemission spectroscopymeasurement indicates that, comparedwith the compact TiO2 (cp-TiO2) layers, themp-TiO2 layers possess a slightly larger work function, which will improve the electron extraction efficiency at the perovskite-TiO2 interface. The PSCswith an additionalmp-TiO2 layer exhibit better performances than thosewith only a cp-TiO2 layer. They suffer from a smaller efficiency loss when enlarging the device area from0.16 to 1.44 cm and exhibit a better long-term stability. About 89%of the initial efficiency is retained after keeping in dry air for 1000 h for the device with an active area of 1.44 cm. For both cases, increasing the active device area is beneficial to long term stability, photoluminescencemeasurement indicates that this is result from the degradation of perovskite films starts at themargin of the cells. Ourwork implies the indispensable role of the additionalmp-TiO2 layer for optimizing the performances of large-area PSCs using TiO2 as the electron transport layer.
THE cr-KEJTO ANALOGUES OF ARGININE, ORNITHINE, AND LYSINE

Although the cr-keto analogues of most of the common natural amino acids have been prepared, there are apparently no reports describing the preparation of the cr-keto acids corresponding to arginine (or-ketod-guanidinovaleric acid), ornithine (oc-keto-&aminovaleric acid), and lysine (CXketo-e-aminocaproic acid). The 2,4-dinitrophenylhydrazones of ac-keto-daminovaleric (l-3) and cr-keto-&guanidinovaleric (4) acids have been isolated; however, the free acids were not obtained. In the present communication the preparation of ar-keto-6-guanidinovaleric acid, as well as a-keto-&nitroguanidinovaleric acid, by enzymatic oxidative deamination (5) of the corresponding L-amino acids is described. Since lysine and ornithine were oxidized relatively slowly, the cr-keto acids corresponding to these amino acids were therefore obtained as the w-N-carbobenzoxy derivatives, by enzymatic oxidation of the more susceptible w-N-carbobenzoxyamino acids. The carbobenzoxy groups were then removed from the resulting cr-keto acids by treatment with hydrobromic acid in acetic acid solution (6), yielding the hydrobromides of the desired compounds. The a-keto analogues of lysine and ornithine would be expected to exhibit tendency to cyclize by condensation of the cY-keto and w-amino groups. However, the properties of the keto analogues of lysine and ornithine include ability to form 2,4-dinitrophenylhydrazones, decarboxylation with hydrogen peroxide to the corresponding w-amino acids, and non-enzymatic transamination with pyridoxamine to form lysine and ornithine, respectively. On the other hand, hydrogenation of these keto acids, or their w-N-carbobenzoxy derivatives, resulted in the formation of pipecolic acid and proline, respectively, a finding compatible mith the expected tendency to cyclization.
An Inverse Relation between cagA+ Strains of Helicobacterpylori Infection and Risk of Esophageal and Gastric Cardia Adenocarcinoma1

Gastric colonization with Helicobacter pylori, especially cagA ' strains, is a risk factor for noncardia gastric adenocarcinoma, but its relationship with gastric cardia adenocarcinoma is unclear. Although incidence rates for noncardia gastric adenocarcinoma have declined steadily, paralleling a decline in //. pylori prevalence, rates for adenocarcinomas of esophagus and gastric cardia have sharply increased in industrialized countries in recent decades. To clarify the role of //. pylori infection in these tumors with divergent incidence trends, we analyzed serum IgG antibodies to //. pylori and to a recombinant fragment of CagA by antigen-specific ELISA among 129 patients newly diagnosed with esophageal/gastric cardia ade nocarcinoma, 67 patients with noncardia gastric adenocarcinoma, and 224 population controls. Cancer risks were estimated by odds ratios (OR) and 95% confidence intervals (CI) using logistic regression models. Infection with cagA+ strains was not significantly related to risk for noncardia gastric cancers (OR, 1.4; CI, 0.7-2.8) but was significantly associated with a reduced risk for esophageal/cardia cancers (OR, 0.4; CI, 0.2â€”0.8). However, there was little association with cagA ~ strains of H. pylori for either cancer site (OR, 1.0 and 1.1, respectively). These findings suggest that the effects of //. pylori strains on tumor development vary by ana tomical site. Further studies are needed to confirm these results and to assess whether the decreasing prevalence of //. pylori, especially cagA + strains, may be associated with the rising incidence of esophageal/gastric cardia adenocarcinomas in industrialized countries.
Expression and Characterization of Mucins Associated with the Resistance to Methotrexate of Human Colonie Adenocarcinoma Cell Line HT291

A series of experiments were conducted to study synthesis and secre tion of inucin in mucus-secreting subpopulations of HT29 human co-Ionic adenocarcinoma cells selected by resistance to methotrexate (MTX). Mucin was quantitated by [3H|glucosamine labeling and chromatography on Sepharose CL-4B. The mucinous nature of the labeled high molecular weight glycoprotein was verified by alkaline borohydride treatment, cesium chloride density gradient ultracentrifugation, and so dium dodecyl sulfate-polyacrylamide gel electrophoresis. The results of these experiments demonstrated that MTX-treated cells have increased amounts of mucin in medium, cytosol, and membrane fractions. This was associated with the increase in the activities of polypeptidyl-/V-acetylgalactosaminyltransferase and /3-1,3-galactosyltransferase com pared to control cells. DEAE-Sephacel chromatography of pHjglu-cosamine-labeled high molecular weight glycoproteins suggest that MTX-treated cells are less acidic compared to controls. Using comple mentary DNA probes for two distinct human intestinal mucins (MUC2 and MUC3) and one mammary mucin (MUC1), it was found that MTX-treated cells expressed more mucin messages compared to untreated cells. These results were consistent with immunoblots using anti-MRP (MUC2 repeat peptide), anti-M3P (MUC3 repeat peptide), 139H2 (MUC1 peptide), anti-T (peanut lectin), anti-Tn (91S8), and anti-sialo-syl Tn (JTlOe) antibodies. These data indicate that MTX-resistant HT29 cells show enhanced secretion and synthesis of mucin as well as expression of MUC1-, MUC2-, and MUC3-related mucin polypeptide epitopes.
CLASSIFICATION OF VILLAGES IN BAFRA DISTRICT ACCORDING TO SMALL RUMINANT EXISTENCE

In this study 103 villages belonged to Bafra district of Samsun province in Turkey was clustered according to existence of small ruminant (sheep and goat) to classify the villages for giving decision support to policymakers. For this aim hierarchical clustering with nearest neighborhood method and Squared Euclidean distance was used. Results showed that most of the villages had same characteristics and only two of 103 villages differ from others according to small ruminant existence. According to results same policies can be applied all the villages in Bafra district except two villages (Tepebasi and Merkez -M) which had more number of animals and business than others.
Analysis of interference between electromagnetic articulography and electroglottograph systems

ANALYSIS OF THE INTERFERENCE BETWEEN ELECTROMAGNETIC ARTICULOGRAPHY AND ELECTROGLOTTOGRAPH SYSTEMS Kelly M. Vonderhaar, B.S. Marquette University, 2016 Electromagnetic Articulography (EMA) has become an integral tool for researchers and clinicians who seek to characterize speech kinematics. The position and orientation of the articulators – which include the teeth, lips, and tongue – are recorded by attaching sensors to the articulators and tracking the movement of the sensors through an electromagnetic field. This has been used by researchers and clinicians to better understand dysarthria and synthesize speech, among other applications. Another speech tool, electroglottography (EGG), is used to analyze the movement of the vocal folds during speech production. This is achieved by measuring the time variation of the contact of the vocal folds and analyzing it with regards to the speech produced. Clinically, EGG is used to identify voice abnormalities, including those without visual or acoustic abnormalities. These systems are not used concurrently because of the electromagnetic field used with the EMA system; NDI and Carstens affirm that metal should be kept out of the field during EMA use. Concurrent use of these systems would lead to simultaneous measurements of the laryngeal and upper airway-articulatory abilities, which could increase understanding of motor speech issues. Parameters derived from the EGG signal could also be incorporated with articulatory parameters to improve synthesized voice quality and synthesize a more realistic voice. The objective of this research is to investigate whether the interference present between the EMA and EGG systems is significant and, if so, to characterize it so the systems can be used simultaneously. Analysis of the interference was obtained through several data collections. The first assessed the degree of interference when the EMA sensors were stationary. The second data set was collected using a model that maintained sensor orientation while changing the sensors’ speed. The final data set was obtained with a model that maintained sensor speed while changing the orientation of the sensors. Sources of interference that were present included the EGG system and orthodontia. The resulting data led to the conclusion that the presence of the EGG or the orthodontic appliances does not cause significant interference.
Study on development mode and regulation of water-land-ecology-economy in Sanjiang Plain, China

Sanjiang Plain is an important grain yield base and ecological demonstration zone of China. Its ecological security, food production, and GDP development can support the sustainable development of SJP. China government focuses on the supply and utilization of resources and grain yield, local government pays attention to the gross domestic product of all sorts of industry, local residents concern the area of paddy and dry lands. This paper takes GDP, grain yield, and ecological service value as our targets under Normal water year and dry year. 8 kinds of land use (dry land, rice (irrigation), rice (rainfed), forest, grassland, wetland, water area, residents), 3 types of industrial development (primary industry, secondary industry, tertiary industry), 3 sorts of water sources (surface water, groundwater, transit water) and 7 ways of water utilization (urban domestic water, rural domestic water, primary industry water, secondary industry water demand, tertiary industry water demand, urban ecological water demand, wetland Ecological water demand) are considered. A comprehensive configuration model of the Sanjiang Plain in the near future (2020) and mid-term future (2025) is presented, which is solved by an optimize software of lingo. The results derived show that the GDP will increase by 50%, the grain output will double, and there is also a slight increase of the ecological service value at 2025.
evidence of the Short Almost Perfect Scale (SAPS) in

: Perfectionism can be understood as a personality trait that establishes excessively high standards for the performance of individuals and ostensibly critical self-evaluations. It is associated with a range of variables, such as anxiety, suicidal tendencies, depression, and low satisfaction with life. Rice et al. (2014) proposed the Short Almost Perfect Scale (SAPS), which overcame some limitations of previous measures (e.g., ambiguity, non-necessary factors). In the present research, we provide psychometric evidence of the SAPS in Brazil. The original two-factor structure was replicated. The items showed good discrimination, level of difficulty, and informativeness for the overall measure. The SAPS also presented acceptable reliability levels, and full measurement invariance across participants' gender, and partial invariance across countries (Brazil and USA). Finally, perfectionism was meaningfully associated with personality traits and human values. In sum, our findings suggest that the SAPS is psychometrically adequate for further use in Brazil.
Interspecific competition and protistan grazing affect the coexistence of 1 freshwater betaproteobacterial strains 2 3 4

The competitive strength of four cosmopolitan freshwater betaproteobacterial isolates was investigated in the presence or absence of bacterivorous flagellates during continuous cultivation in artificial minimal medium at two dilution rates. Bacteria reached similar abundance and growth rate in monocultures, but in co-cultures, two strains (Acidovorax sp. and Massilia sp.) displayed significantly higher numbers and growth rates. These potential cross-feeding benefits were also supported by a high nutritional versatility of the two strains. In contrast, Hydrogenophaga sp. was seemingly less competitive or even inhibited by co-cultivation, and Limnohabitans planktonicus displayed striking abundance fluctuations. The latter two strains were least versatile in the uptake of different carbon sources and thus suffered more from interspecific competition. Moreover, remarkable strain-specific responses appeared when bacteria experienced increasing loss rates due to grazing and/or raised dilution rates. Limnohabitans planktonicus developed no successful defence strategy and was close to extinction. Massilia sp. formed grazing-resistant filaments exclusively at low dilution, but was highly reduced at increased flowthrough. Acidovorax sp. was selectively ingested, but compensated grazing losses with accelerated growth rates and formed (co-)aggregates together with Hydrogenophaga sp. to escape predation at high flowthrough. These species-specific interactions, growth responses and defence strategies strongly modulate mixed microbial assemblages and the microbial food web.

Title: The role of p21-activated kinases (PAKs) in glucose homeostasis and skeletal muscle glucose uptake

Skeletal muscle glucose transport is essential for maintaining whole body glucose homeostasis and skeletal muscle accounts for the majority of glucose disposal in response to insulin. Glucose transport into skeletal muscle can be induced by several stimuli, such as insulin and muscle contraction, which both have been shown to activate group I p21-activated kinases (PAKs). Skeletal muscle expresses two group I PAK isoforms but the role of these in muscle glucose uptake has not been determined. Recent evidence suggests that p21-activated kinase (PAK) 1 may play a role in insulin-stimulated GLUT4 translocation and that PAK1/2 signaling is markedly impaired in insulin resistant skeletal muscle. Thus, the current study aimed to test the hypothesis that PAKs are important regulators of glucose homeostasis and skeletal muscle glucose uptake. To elucidate the role for group I PAKs in skeletal muscle glucose uptake, we determined glucose uptake in mature skeletal muscle incubated with a pharmacological inhibitor of group I PAKs, IPA3, or in mice with knockout (KO) of either PAK1, PAK2, or joint KO of both PAK1 and PAK2 (d1/2KO). In contrast to our hypothesis, we found that lack of PAK1 did not affect glucose uptake in response to insulin or contraction. Lack of PAK2 protein only mildly reduced insulin-stimulated glucose transport in EDL muscle. We conclude that PAK1/2 proteins are not major regulators of skeletal muscle glucose uptake but that PAK2 may play a minor role.

Influence of PDMS encapsulation on the sensitivity and frequency range of fiber-optic interferometer

Fiber-optic sensors are one of the dynamically developing areas of photonics and photonic applications. This group of sensors can also include fiber-optic interferometers which enable very sensitive sensing. They are entirely passive regarding power supply, and immune to electromagnetic interference. This type of sensor is dependent on the phase change. It mostly used in the field which requires high measurement accuracy. We can achieve a change of sensitivity in the order of 10-8. The fundamental problem of fiber-optic interferometry is a design and imposition (encapsulation) of the measuring arm and reference arm of the interferometer. Polydimethylsiloxane elastomer (PDMS) is one of the possibilities to encapsulation of the sensory arm. Two-component PDMS Sylgard 184 is used type. The article analyzes the effect of encapsulation into a PDMS of the measuring arm of the interferometer to frequency response and sensitivity of the Mach-Zehnder interferometer with the division of power in a ratio of 1:1 (measuring arm and reference arm). Input power set to a reference value of 1 mW, this value was constant for all performed experimental measurements. The generator of a harmonic signal with fixed amplitude signal used for analysis of the frequency characteristic of the interferometer. The application written in LabView development environment, evaluated the amplitude-frequency spectra of the signal. Repeated test of assembled prototype verified the measured results.

Evolution of alkaline characteristics in bauxite residue under phosphogypsum remediation

This study reports the innovative application of phosphogypsum waste from the manufacture of phosphoric acid with highly alkaline Bauxite residue generated during alumina production. The hypothesis was that the environmental risk associated with bauxite residue disposal areas (BRDAs) could be mitigated economically by use of a readily available acidic waste material. Therefore, mixtures of phophogysum and bauxite residue were examined as a function of time to discern the reactions occurring. The main conclusions were as follows: the pH of bauxite residue reduced from 10.83 to ca. 8.70 when 1.5 wt% phosphogypsum was added for 91 days; the removal rates of free alkali species and exchangeable Na ions were over 98 and 75.88 %, respectively; significant positive correlations (P<0.05) existed between pH and free alkali, exchangeable sodium, providing new indicators for alkaline regulation; the effect of free alkali composition was CO3 > OH> AlO2 > HCO3; the presence of alkaline materials decreased from 52.8 to 48.6 % and a small amount of gypsum stably presented in bauxite residue which continuously provided Ca2+ to the liquid phase and inhibited dissolution of chemically combined alkali; phosphogypsum promoted formation of macroaggregate structure, increased Ca, decreased Na and Al on the suface of bauxite residue, and ultimately promoted soil formation of bauxite residue.
Full Paper Engineered ACC deaminase-expressing free-living cells of Mesorhizobium loti show increased nodulation effi ciency and competitiveness on Lotus spp.†

Inoculations with rhizobia may be vital to overcome nitrogen defi ciencies in soil. However, some strains often fail to nodulate due to competition with native soil populations (Maier and Triplett, 1996; Vlassak and Vanderleyden, 1997). One approach to solve this problem is their genetic enhancement. The gaseous phytohormone ethylene inhibits the early signal transduction cascade that characterizes and governs the earlier plant physiological changes during the nodulation process of legumes (Nukui et al., 2004; Oldroyd et al., 2001). It affects the infection thread initiation and elongation (Gage, 2004) and limits nodule number and development in Medicago truncatula and M. sativa (Penmetsa and Cook, 1997; Peters and Crist-Estes, 1989), which form indeterminate nodules, and in Lotus japonicus, which forms determinate ones (Nukui et al., 2000). In contrast, no inhibition has been found for Glycine max (Schmidt et al., 1999). Some rhizobia have developed mechanisms to lower plant ethylene and improve root nodulation. One of them relies on the constitutive production of rhizobitoxine, an amino-acid found in Bradhyrhizobium elJ. Gen. Appl. Microbiol. , 56, 331‒338 (2010)
