description: The modified MgO nanoparticles (m-MgO-NPs) by a copolymer containing the malic acid and low molecular weight poly(L-lactide) (poly(L-lactide-co-malic acid), PLMA) have been successfully prepared. MgO nanoparticles (MgO-NPs) were coated by the PLMA and m-MgO-NPs were uniformly dispersed in the PLLA matrix to a novel biocomposite material (PLLA/m-MgO-NPs) with more excellent interface bonding and uniformer dispersion, compared to the PLLA/MgO-NPs. Compared to neat PLLA and PLLA/MgO-NPs film, the m-MgO-NPs not only shown the obvious neutralization effect on the acidic solution in the degradation of the PLLA and better hydrophilicity, but also exhibited the higher cell viability and decrease the toxicity to the cell in the degradation process of PLLA in vitro. In addition, m-MgO-NPs also reduced the degradation rate of the PLLA. The mechanisms for the excellent dispersion of nanoparticles, enhanced pH stability, reduced degradation rate of the PLLA and the cell viability in vitro in the case of PLLA/m-MgO-NPs have also been proposed and discussed in detail.

description: The multidentate Schiff-base ligand N′-(1-(pyrazin-2-yl)ethylidene)isonicotinohydrazide (HL) has been prepared. Reaction with zinc, copper, and silver nitrate afford three complexes, [Zn(HL′)2](NO3)2·3H2O (1), {[Cu2(L)2(NO3)(H2O)2]·NO3}n (2) and {[Ag2(L)2]·3H2O}n (3). These complexes have been characterized by elemental analysis, IR spectroscopy, and single-crystal X-ray diffraction. In 1, HL is a neutral tridentate ligand, whereas in 2 and 3, HL is a deprotonated tetradentate ligand. The hydrogen bonding interactions between NO3− and the host framework result in various supramolecular polymeric structures: a 2-D layer for 1 and 3-D network for 2 and 3. The antibacterial activities of these complexes have been investigated and the results indicate that 3 showed good antibacterial activities.

description: La stratégie ‘Energie 2020’ affirme que le futur de l’industrie, l’économie et la population dépendent de l’énergie durable et abordable et confirme les objectifs ’20-20-20’ à réduire l’effet de serre de 20%, l’augmentation de l’énergie renouvelable à 20% et une amélioration de 20% de l’efficacité énergétique. Le défi majeur, aujourd’hui, est l’adaptation et la modernisation des bâtiments existants afin d’atteindre un équilibre annuel de zéro énergie à l’échelle d’un quartier dans le but d’atteindre le niveau d’autonomie énergétique. La recherche introduit la notion de ‘smart ground’ guidée par : (a) la localisation d’un quartier et (b) la morphologie pour assurer sa viabilité. Trois leviers d’action ont été développés afin de définir son contexte : 1. L’optimisation des besoins actuels en énergie, 2. L’hybridation énergétique et 3. L’organisation du stockage (en termes d’énergie, eau et déchets). Ce travail ouvre de nombreuses futures perspectives de recherche qui devraient être largement étudiées afin de développer les besoins dans un contexte concret et opérationnel. Le but de cet article est de proposer une approche méthodologique pour l’encadrement d’un quartier zéro énergie via l’approche systémique et le développement d’un outil d’évaluation pour examiner l’opportunité d’étendre le concept à l’échelle du quartier.

description: Curative treatment of pediatric cancer not only focuses on long-term survival, but also on reducing treatment-related side effects. Advantages of particle therapy are mainly due to their physical ability of significantly reducing integral dose. Methods. Between January 2009 and December 2012, we treated 83 pediatric patients (aged 21 and younger) at the Heidelberg Ion Therapy Center at University Hospital of Heidelberg (HIT). In total 56 patients (67%) received proton irradiation, while 25 (30%) patients were treated with carbon ions (C12). Two patients received both treatments (3%). Treatment toxicity was analyzed retrospectively and documented according to the CTCAE/RTOG classification. In a second step, treatment toxicity from ion therapy was analyzed in comparison to treatment toxicity during photon irradiation of a comparable historical group of 19 pediatric patients. Results. In all patients, particle therapy was tolerated well (median follow-up time 3.7 months), children (20 patients) with at least two follow-up visits showed a median follow-up time of 10.2 months. During the first two months patients mainly suffered from radiogenic skin reaction (63%), mucositis (30%), headache and dizziness (35%) as well as nausea and vomiting (13%). Severe toxicity reaction (grade II–IV) was only seen in patients who had intensive simultaneous chemotherapy or who had undergone several operations in the irradiated area before radiotherapy (18%). Treatment toxicity during ion therapy was comparable to treatment toxicity from photon irradiation of a historical group. Conclusions. In comparison to conventional therapy, patients with particle therapy do not suffer from increased acute treatment-related toxicity during the first months. More experience with particle therapy will be needed during the next years to help to thoroughly evaluate the high potential of ion therapy.

description: An efficient one-step domestication method with mixed electron acceptors and short-time post-aeration was developed for the enrichment culture of denitrifying phosphorus removal sludge. The acclimation time, performance of nitrogen and phosphorus simultaneous removal and microbial community structure were investigated to reveal the difference among the obtained phosphorus removal sludge using different acclimation ways. Results showed that the proposed method with optimal proportion of nitrite and nitrate could significantly shorten domestication time (28 days) compared with the traditional two-step method (60 days), but exerted nearly no influence on the removal efficiency of nitrogen and phosphorus. High-throughput sequencing revealed that similar microbial community structure of DPAOs sludge was obtained with different acclimation methods. Compared with seed sludge, microbial community shifted obviously, and the dominant microbial population of Dechloromonas-related phosphorus removal bacteria increased significantly. It could be inferred that the appropriate concentration of nitrite was conducive to the rapid enrichment of DPAOs under alternative anaerobic/anoxic operation. Meanwhile, anaerobic/oxic condition was favorable for the enrichment of Candidatus Accumulibacter-related phosphorus removal organisms, and short-time post-aeration in the proposed method could reduce the potential public health hazard.

description: Glycated hemoglobin (HbA1c) measurement from whole blood (WB) samples is inconvenient for epidemic surveillance and self-monitoring of glycemic level. We evaluated HbA1c measurement from WB blotted on filter paper (FP), which can be easily transported to central laboratories, with high-performance liquid chromatography (HPLC) and immunoturbidimetric assay (ITA). WB was applied to Whatman filter paper. By using HPLC and WB samples as reference methods, these FP samples were evaluated on HPLC and ITA. Inter- and intra-assay variation, WB vs. FP agreement and sample stability at 20–25 °C and −70 °C were assessed by statistical analysis. Results showed that the coefficient of variation (CV, %) of FP samples for HPLC and ITA were 0.44–1.02% and 1.47–2.72%, respectively (intra-assay); 2.13–3.56% and 3.21–4.82%, respectively (inter-assay). The correlation of WB HPLC with FP analyzed using HPLC and ITA are both significant (p < 0.001). Sample stability showed that FP method up to 5 days at 20–25 °C and 5 weeks at −70 °C is accurate and reproducible. In conclusion, FP samples analyzed by HPLC and ITA can both provide an alternative to WB for HbA1c measurement, supporting the use of FP method in epidemic surveillance and healthcare units.

description: Esta pesquisa objetivou realizar o levantamento ergonômico do trabalho no setor hoteleiro, visando à melhorias e bem-estar aos trabalhadores na cidade de Marabá, Pará. A amostra utilizada nesse estudo foi de 16 recepcionistas pertencentes a 06 hotéis de porte pequeno e médio. A coleta de dados foi realizada através de questionários semiestruturados e mensuração do posto de trabalho (antropometria e mobiliário). Para a análise dos dados foi utilizada estatística descritiva, sob as abordagens qualitativa e quantitativa. A partir da comparação entre medidas do mobiliário e antropometria, foi demonstrada a incompatibilidade entre os componentes do posto de trabalho, fato que pode comprometer a saúde dos recepcionistas a longo prazo. Além disso, observou-se um quadro de insatisfação instalado ocasionado pela exigência em assumir constantemente a postura de pé e também sentada, com deslocamentos contínuos e desconfortos gerados pela desorganização espacial do ambiente de trabalho.

description: Canine lymphoma is a prevalent cancer affecting the lymphatic system of dogs, characterized by the abnormal proliferation of lymphocytes. This malignancy can manifest as a localized or systemic disease, with multicentric lymphoma being the most common form. While the exact etiology remains unclear, certain breeds show predisposition, suggesting a potential genetic component. Diagnosis typically involves fine needle aspirate or biopsy of enlarged lymph nodes, with additional tests like immunohistochemistry aiding in subtype classification. Clinical signs vary based on the affected organs, ranging from lymph node enlargement to gastrointestinal or respiratory symptoms. Prognosis depends on various factors, with untreated dogs having a survival time of four to six weeks, while those undergoing chemotherapy may achieve remission with an average survival time of around one year. Further research is needed to elucidate the underlying mechanisms of canine lymphoma and improve treatment outcomes for affected dogs.

description: The aim of the master thesis was to identify the soil organic carbon content (kg/m²) as a function of land use and pedogenic parameters. Therefor soil particle size distribution, bulk density, pH, organic carbon and total nitrogen contents were measured. The dataset provides values about physical and chemical soil parameters as well as the soil organic carbon (SOC) content at different soil depths (0-10cm, 10-30cm and 0-30cm) under varying vegetation cover (grasslands and forest) and elevation at the Modelregion Stubai Valley, Austria (municipalities Neustift + Fulpmes). The samples were taken in Summer 2012 and the measurements were conducted in fall 2012. For the SOC calculations paramters from 53 sites from earlier projects were added. The dataset also contains shapefiles representing the samplings sites and the sampling point distribution. The dataset also contains sampling points from earlier and present projects where C/N, NO3, NH4, soil type and pH values were measured.

description: Ethyl acetate fraction (EAF) from Rhus verniciflua Stokes is an important source of bioactive compounds. The aim of this study was the tentative identification and quantification of phenolic compounds, comparison of the phenolic structure–antioxidant activity relationships. Twelve compounds of EAF belonging to polyphenol types were detected by high performance liquid chromatography and analysed on line with negative ion electrospray ionisation tandem mass spectrometry, which were ethoxy 3-hydroxy benzoic acid, gallic acid (GA), 3,4-dihydroxy amygdalic acid, gallic acid cetyl ester, protocatechuic acid (PA), fustin, ethyl gallate (EG), garbanzol, fisetin, sulfuretin, butin and 3,7-dihydroxyflavanone-4′-rhamnoside. The antioxidant activity were evaluated based on the different types of radical scavenging capacities, i.e. DPPH·, ABTS·+ and OH. The antioxidant capacity of EAF mainly depended on the GA, EG, PA, fisetin, sulfuretin and butin. The phenolics exhibited a dose-dependent behaviour and high antioxidant ability.

description: Purpose: Higher levels of serum phosphate are strongly linked to increased risk of cardiovascular disease and therapies aimed to lower serum phosphate are employed in the management of patients with chronic kidney disease (CKD). Data are limited, however, on serum phosphate as a risk factor for microvascular disease in community-based populations. It is important to determine the impact of novel risk factors, such as phosphate, on the microvasculature. Methods: We conducted a prospective study of 3919 individuals in the Multi-Ethnic Study of Atherosclerosis (MESA) and 3544 individuals in the Beaver Dam Eye Study (BDES) to test the associations of serum phosphate with retinopathy and retinal vessel caliber, and change in retinopathy severity and change in retinal vessel caliber. Results: Mean (standard deviation) serum phosphate was 3.66 (0.52) mg/dl in the MESA and 3.77 (0.55) mg/dl in the BDES. In multivariable adjusted models, phosphate was significantly associated with prevalent retinopathy in the MESA (Odds Ratio [OR] per 1 mg/dl increase in phosphate, 1.22; Confidence Interval [CI] 1.02–1.47) and the BDES (OR 1.06; CI 1.01–1.11). In stratified analyses, these relationships were even stronger and only seen in individuals with diabetes in both the MESA (OR 1.81; CI 1.30–2.53) and the BDES (OR 1.16; CI 1.05–1.29). Phosphate was not associated with incident or change in retinopathy severity, nor any retinal caliber outcome. Conclusions: Among community-living individuals with low prevalence of CKD, higher serum phosphate was associated with prevalent retinopathy in individuals with diabetes. Further longitudinal assessments in patients with diabetes necessitate further investigation.

модель инфраструктурного возврата

description: В статье рассматриваются вопросы планирования и мониторинга проектов цифровой экономики, направленных на развитие информационно-вычислительной инфраструктуры. На основе анализа современных тенденций выделено отдельное направление по управлению инфраструктурными проектами. В частности, предложена система поддержки принятия решений по оценке перспективности и инвестиционной привлекательности инновационных проектов в современных условиях. Инновационный характер выполнения проектов в данном случае определяется стеком применяемых информационных технологий, от которых в рамках цифровой экономики ожидаются ключевые преимущества. С этой точки зрения управление инновационными проектами цифровой экономики сводится к стимулированию цифровых платформ, обеспечивающих эмиссию сервисов и мотивации проектов, обеспечивающих максимальный инфраструктурный возврат. В качестве основного показателя эффективности развития ИТ инфраструктуры предлагается оценка инфраструктурного возврата, которая позволяет оценить риски и перспективы эмиссии новых сервисов. В статье предложена методика расчета инфраструктурного возврата в рамках выполнения проектов цифровой экономики. Приведен пример реализации этой методики для планирования и мониторинга проектов с инфраструктурным возвратом на практике для Национальной программы «Внутренние затраты на развитие цифровой экономики за счет всех источников по доле в валовом внутреннем продукте страны». В качестве примера рассмотрен проект создания четырех космических аппаратов «Экспресс-РВ» на высокоэллиптических орбитах в модели инфраструктурного возврата. Результаты исследования могут быть использованы в разработке инновационных систем управления в цифровых социальных и экономических системах.
Chloroplastic iron-sulfur scaffold protein NFU3 is essential to overall plant fitness

description: A previous study showed that Nitrogen-Fixing-subunit-U-type protein NFU3 may act an iron-sulfur scaffold protein in the assembly and transfer of 4Fe-4S and 3Fe-4S clusters in the chloroplast. Examples of 4Fe-4S and 3Fe-4S-requiring proteins and complexes include Photosystem I (PSI), NAD(P)H dehydrogenase, and ferredoxin-dependent glutamine oxoglutarate aminotransferases. In this paper, the authors provided additional evidence for the role of NFU3 in 4Fe-4S and 3Fe-4S cluster assembly and transfer, as well as its role in overall plant fitness. Confocal microscopic analysis of the fluorescently-tagged NFU3 protein confirmed the chloroplast localization of the NFU3 protein. Detailed analysis of chlorophyll fluorescence data revealed that a substantial increase in minimal fluorescence is the primary contributor to the decrease in PSII maximum photochemical efficiency observed in the nfu3 mutants. The substantial increase in minimal fluorescence in the nfu3 mutants is probably the result of an impaired PSI function, blockage of electron flow from PSII to PSI, and over-accumulation of reduced plastoquinone at the acceptor side of PSII. Analyses of seed morphology and germination showed that NFU3 is essential to seed development and germination, in addition to plant growth, development, and flowering. In summary, NFU3 has wide-ranging effects on many biologic processes and is therefore important to overall plant fitness. NFU3 may exert these effects by modulating the availability of 4Fe-4S and 3Fe-4S clusters to 4Fe-4S and 3Fe-4S-requiring proteins and complexes involved in various biologic processes.

description: Rigid adsorbents used as matrix skeleton have advantages over soft gel media for downstream processing of proteins. The adsorption of bovine serum albumin (BSA) has been investigated on a rigid ceramic monolith coated with cross-linked microporous agarose (D5). The physical properties of the adsorbent and the adsorption equilibria, adsorption kinetics, and mass transfer behavior have been studied for five different flow rates, with a pH value ranging from pH 4.5 to 7.0. The optimal working flow rate was 14.0 cm3/min, and using this flow rate, increasing the pH does not generate a significant improvement in the adsorption capacity. The rates of BSA adsorption have been measured and it was possible to describe a theoretical model, in which the mass transfer involves a dispersion coefficient (kdisp), which describes the mass transfer in the adsorbent surface, from the volume of the protein solution to the agarose surface. This parameter presents an exponential tendency by increasing the flow rate from 2.37 × 10−6 to 87.40 × 10−6 cm/s for n = 1. Values obtained for the adsorption kinetic constant (kads) followed the trend of the mass transfer parameter, increasing with the flow rate from 1.94 × 104 to 117.39 × 104 cm2/mol s. The theoretical model predicts the protein concentration in equilibrium for successive column reuses and it can be readily used to determine the optimal reuse of column. Likewise, for a maximum flow rate of 14 cm3/min, pressure drop was 0.04 MPa, being an advantage in front of packed columns that have higher pressure drop.

description: Below are a list of our main hypotheses:

1. We hypothesize that Manichaeism will predict social distance differences between liberals and conservatives, even after controlling for ideology.

2. We hypothesize that Manichaeism will predict social distance differences between ingroups and outgroups, even after controlling for ideological extremity.

3. We hypothesize that Manichaeism will predict outgroup distancing more than ingroup closeness.

4. We hypothesize that Right Wing Authoritarianism and Social Dominance Orientation will predict preference for conservative over liberal closeness, but that this relationship will be explained by ideology.

5.We hypothesize that RWA and SDO will not predict ingroup or outgroup social distance or liberal conservative intergroup social distance differences.

description: Multiple imputation is a common approach for dealing with missing values in statistical databases. The imputer fills in missing values with draws from predictive models estimated from the observed data, resulting in multiple, completed versions of the database. Researchers have developed a variety of default routines to implement multiple imputation; however, there has been limited research comparing the performance of these methods, particularly for categorical data. We use simulation studies to compare repeated sampling properties of three default multiple imputation methods for categorical data, including chained equations using generalized linear models, chained equations using classification and regression trees, and a fully Bayesian joint distribution based on Dirichlet process mixture models. We base the simulations on categorical data from the American Community Survey. In the circumstances of this study, the results suggest that default chained equations approaches based on generalized linear models are dominated by the default regression tree and Bayesian mixture model approaches. They also suggest competing advantages for the regression tree and Bayesian mixture model approaches, making both reasonable default engines for multiple imputation of categorical data. Supplementary material for this article is available online.

description: A Cd(II)-MOF, {[Cd(L)(4,4′-bipy)]·H2O·DMF}n (1) (L = nicotinic acid (2,4-dihydroxybenzylidene)-hydrazide and 4,4′-bipy = 4,4′-bipyridine), has been synthesized and characterized by microanalyses, FTIR, TGA, and single-crystal X-ray diffraction. Additionally, powder X-ray diffraction was performed to check the phase purity of the synthesized compound. Single-crystal X-ray diffraction reveals that 1 has a 2D grid network. Photoluminescent sensing of nitrobenzene, Fe(III) and CrO42− ions indicates that 1 could be a candidate for developing selective luminescent sensors for these species. Theoretical calculations have been performed to gain insight into the possible mechanism of quenching effect in emission on addition of nitrobenzene in 1 which supports the mechanism operating through ground state charge transfer between 1 and nitrobenzene.

description: Semotion'17 slides for "Consequences of unhappiness while developing software"ABSTRACT--The growing literature on affect among software developers mostly reports on the linkage between happiness, software quality, and developer productivity. Understanding the positive side of happiness – positive emotions and moods – is an attractive and important endeavor. Scholars in industrial and organizational psychology have suggested that also studying the negative side – unhappiness – could lead to cost-effective ways of enhancing working conditions, job performance, and to limiting the occurrence of psychological disorders. Our comprehension of the consequences of (un)happiness among developers is still too shallow, and is mainly expressed in terms of development productivity and software quality. In this paper, we attempt to uncover the experienced consequences of unhappiness among software developers. Using qualitative data analysis of the responses given by 181 questionnaire participants, we identified 49 consequences of unhappiness while doing software development. We found detrimental consequences on developers’ mental well-being, the software development process, and the produced artifacts. Our classification scheme, available as open data, will spawn new happiness research opportunities of cause-effect type, and it can act as a guideline for practitioners for identifying damaging effects of unhappiness and for fostering happiness on the job.

description: The combinational fungicide suspension (11.7% propiconazole + 7% azoxystrobin), developed by Syngenta Co., Ltd., is very effective for the control of Alternaria black spot on ginseng. A simple and effective method was developed for determining propiconazole and azoxystrobin residues by high-performance liquid chromatography coupled with tandem mass spectrometry (HPLC-MS/MS). The recoveries of propiconazole ranged from 81.0% to 98.0% with relative standard deviations (RSDs) of 1.23–8.46%, while the recoveries of azoxystrobin ranged from 83.2% to 98.8% with RSDs of 3.29–9.50%. For the dissipation kinetics, the combinational fungicide was sprayed with dosage of 225 g a.i.ha−1 (1.5 times of recommended dosage) in ginseng and soil at two different locations. The dissipation kinetics followed the first-order kinetics with half-lives of 6.66–13.33 days for propiconazole and 4.92–9.12 days for azoxystrobin. Based on the terminal residues data, the preharvest interval (PHI) could be 35 days at recommended dosage in ginseng. The dietary exposure risk was estimated by risk quotient (RQ). The result showed that the RQ value was obviously lower than RQ = 1, indicating that spraying propiconazole and azoxystrobin in ginseng at recommended dosage was safe for human beings.
