Abstract
A series of Mg doped LaNiO3 nano particles by solids denoted as LaNi1-xMgxO3-δ (x = 0, 0.1, 0.2, 0.4, 0.6, 0.8 and 1) were prepared by the modified citrate sol-gel method and investigated as catalysts for combine reforming of methane (CRM).The resulting oxides were examined by using XRD, BET, ICP, SEM, EDS, TEM, TPR and TGA techniques, under the condition of as-synthesized and used samples. The results showed that highly homogeneous and crystalline oxides with particle sizes in the range of nanometers were obtained through this synthesis method. The XRD patterns of the prepared LaNi1-xMgxO3-δsolids confirmed with increasing Mg amount not only perovskite structure could not form correctly but also the spinel (La2NiO4) and oxide phases (MgO and NiO) are produced on the sample surface. Also according to BET results, the presence of these oxide phases lead to the increase in the surface area of samples .Although, increasing in surface area had not a significant effect in results of activity tests. TPR analysis revealed that the reduction of the prepared samples became more difficult by increasing the degree of substitution (x). The effects of the partial substitution of Ni by Mg and reaction temperatures (600–800 °C) were investigated in CRM process, after reduction of the samples under hydrogen. Although, all catalysts, except LaMgO3, were found to be highly active toward the syngas production during the CRM process but substitution of Ni by Mg could not improve the catalytic activity of the LaNi1-xMgxO3-δ in this process. The catalytic activity in the steady state was found to decrease in the following order:

$${\text{LaNi}}{{\text{O}}_{\text{3}}} \gt {\text{LaN}}{{\text{i}}_{{\text{0}}{\text{.4}}}}{\text{M}}{{\text{g}}_{{\text{0}}{\text{.6}}}}{{\text{O}}_{{\text{3 - }}\delta }} \gt {\text{LaN}}{{\text{i}}_{{\text{0}}{\text{.6}}}}{\text{M}}{{\text{g}}_{{\text{0}}{\text{.4}}}}{{\text{O}}_{{\text{3 - }}\delta }} \gt {\text{LaN}}{{\text{i}}_{{\text{0}}{\text{.9}}}}{\text{M}}{{\text{g}}_{{\text{0}}{\text{.1}}}}{{\text{O}}_{{\text{3 - }}\delta }} \gt {\text{LaN}}{{\text{i}}_{{\text{0}}{\text{.8}}}}{\text{M}}{{\text{g}}_{{\text{0}}{\text{.2}}}}{{\text{O}}_{{\text{3 - }}\delta }} \gt {\text{LaMgO3 - }}\delta$$
Of course, according to the TPR and TGA results, the stability of the samples increased and the coke deposits on the catalyst surface decreased with increasing of x, respectively.

Abstract

Background
Prevention and treatment of obesity is a way to reduce cardiovascular disease, diabetes and depression. Pumpkin as a favorable plant has different properties notably antioxidant, lipid-lowering and anti-diabetic potential. The aim of this study was to assess the anti-obesity effects of pumpkin in diet-induced obese rats.

Methods
Thirty adult male Wistar rats were randomly divided into five groups (n=6) of healthy control, dietary fatty control rats, and three experimental dietary fatty rats that received hydro-alcoholic extract of pumpkin once daily at doses 100 and 200 and 400 mg/kg, respectively. At the end of 6 weeks, lipid profile, atherogenicity, liver enzymes, and oxidative stress status were measured.

Results
Pumpkin in a dose-dependent manner dramatically decreased triglycerides and low-density lipoprotein, and liver enzymes while high-density lipoprotein was markedly increased in treated groups. Pumpkin also increased glutathione level in comparison with obese control group.

Conclusions
Pumpkin ameliorated oxidative stress and dyslipidemia in obese rats, leading to decrease cardiovascular disease risk in obesity.
Sensitivity of Purchasing Power Parity Estimates to Estimation Procedures and their Effect on Living Standards Comparisons
Authors: Majumder Amita , Ray Ranjan , Santra Sattwik 
Published: October 2017

AbstractThe motivation of this exercise is to compare the Purchasing Power Parities (PPPs) calculated using different procedures and study the sensitivity of global rankings of regions based on living standards to the PPPs used. The empirical comparison involves the GEKS, weighted CPD, GK, EWGK and the True Cost of Living Index (TCLI) based PPP estimation procedures with the Indian Rupee used as the numeraire currency. The published ICP PPPs for 2011 are used as benchmark for the non ICP PPPs obtained in this study. Evidence confirming the “Gershenkeron effect,” that affects the additive GK procedure, is provided. The results suggest that the EWGK PPPs, which are also additive, do not suffer from the extent of bias of the GK PPPs. The paper also provides evidence on the large variation in the TCLI based PPPs across expenditure quintiles originating from variation in preferences between expenditure classes. This suggests departure from the current ICP practice of providing one PPP for the entire country and points to the need to estimate PPPs by different expenditure classes. The empirical evidence points to the rich potential for the rarely used TCLI in future PPP calculations.
Advances in optoplasmonic sensors – combining optical nano/microcavities and photonic crystals with plasmonic nanostructures and nanoparticles

Published: October 2017

Abstract
Nanophotonic device building blocks, such as optical nano/microcavities and plasmonic nanostructures, lie at the forefront of sensing and spectrometry of trace biological and chemical substances. A new class of nanophotonic architecture has emerged by combining optically resonant dielectric nano/microcavities with plasmonically resonant metal nanostructures to enable detection at the nanoscale with extraordinary sensitivity. Initial demonstrations include single-molecule detection and even single-ion sensing. The coupled photonic-plasmonic resonator system promises a leap forward in the nanoscale analysis of physical, chemical, and biological entities. These optoplasmonic sensor structures could be the centrepiece of miniaturised analytical laboratories, on a chip, with detection capabilities that are beyond the current state of the art. In this paper, we review this burgeoning field of optoplasmonic biosensors. We first focus on the state of the art in nanoplasmonic sensor structures, high quality factor optical microcavities, and photonic crystals separately before proceeding to an outline of the most recent advances in hybrid sensor systems. We discuss the physics of this modality in brief and each of its underlying parts, then the prospects as well as challenges when integrating dielectric nano/microcavities with metal nanostructures. In Section 5, we hint to possible future applications of optoplasmonic sensing platforms which offer many degrees of freedom towards biomedical diagnostics at the level of single molecules.
The halogen bond: Nature and applications
Authors: Costa Paulo J. 
Published: October 2017

Abstract
The halogen bond, corresponding to an attractive interaction between an electrophilic region in a halogen (X) and a nucleophile (B) yielding a R−X⋯B contact, found applications in many fields such as supramolecular chemistry, crystal engineering, medicinal chemistry, and chemical biology. Their large range of applications also led to an increased interest in their study using computational methods aiming not only at understanding the phenomena at a fundamental level, but also to help in the interpretation of results and guide the experimental work. Herein, a succinct overview of the recent theoretical and experimental developments is given starting by discussing the nature of the halogen bond and the latest theoretical insights on this topic. Then, the effects of the surrounding environment on halogen bonds are presented followed by a presentation of the available method benchmarks. Finally, recent experimental applications where the contribution of computational chemistry was fundamental are discussed, thus highlighting the synergy between the lab and modeling techniques.
Mapping Second Chromosome Mutations to Defined Genomic Regions inDrosophila melanogaster
Authors: Kahsai Lily , Cook Kevin R 
Published: October 2017

AbstractHundreds of Drosophila melanogaster stocks are currently maintained at the Bloomington Drosophila Stock Center with mutations that have not been associated with sequence-defined genes. They have been preserved because they have interesting loss-of-function phenotypes. The experimental value of these mutations would be increased by tying them to specific genomic intervals so that geneticists can more easily associate them with annotated genes. Here, we report the mapping of 85 second chromosome complementation groups in the Bloomington collection to specific, small clusters of contiguous genes or individual genes in the sequenced genome. This information should prove valuable to Drosophila geneticists interested in processes associated with particular phenotypes and those searching for mutations affecting specific sequence-defined genes.
Damoklesschwert oder Symbolpolitik? – Die Rückforderung von Bankerboni im Spiegel des Arbeitsrechts

Zusammenfassung
Anfang August 2017 trat die Verordnung zur Änderung der Institutsvergütungsverordnung (InstVergV) in Kraft. Eine der wesentlichen Änderungen soll die Institute verpflichten, bereits ausgezahlte variable Vergütungsbestanteile von Mitarbeitern in Fällen schwerwiegenden Fehlverhaltens zurückzufordern. Dies wurde auf Grundlage der InstVergV in der zuvor geltenden Fassung noch für „mit dem deutschen Arbeitsrecht (…) nicht vereinbar“ gehalten. Der folgende Beitrag soll dieser kategorischen Einschätzung zum Trotz Mittel und Wege zur Umsetzung der aufsichtsrechtlichen Vergütungsvorgaben im Einklang mit dem Arbeitsrecht – insbesondere mit dem Kündigungsschutzrecht und den AGB-rechtlichen Anforderungen – aufzeigen.

IN VIVO INTERACTION OF PROPYLTHIOURACIL WITH SODIUM IODIDE (Na131I) RADIOPHARMACEUTICAL IN RATS (Rattus norvegicus).. The aim of this research is to determine the effect of propylthiouracil (PTU) treatment to pharmacokinetics interaction and biodistribution profile of Na131I radiopharmaceuticals. Three groups of animal model were used in this experiment, i.e. experimental animals which given PTU for 1 time (onset or A groups), PTU for six days (B Groups) and without treatment (control or C Groups). Pharmacokinetics and biodistribution test were conducted by giving PTU per oral and after 24 hours, continued by giving Na131I solution per oral. In pharmacokinetics test, percentage of injection dose/gram of blood (%ID/g) was calculated to determine the absorption, distribution and elimination half time. In biodistribution test, percentage of injection dose/gram of organs was calculated to determine the accumulation of Na131I in spesific organs. The results showed that the absorption half time of A, B and C groups were 3.14 ± 1.42, 2.49 ± 0.49 and 2.52 ± 0.7 hours, respectively. The distribution half time of A, B and C groups were 10.58 + 5.85, 12.92 + 3.75 and 11.42 + 3.15 hours, respectively. The elimination half time of A, B and C groups were 113.03 + 46.03, 96.57+ 47.76 and 196.71 + 145.21 hours, respectively. Biodistribution test results showed that the accumulation of Na131I in thyroid of A, B and C groups were 1.31 + 0.45, 5.03 + 0.55 and 4.45 + 2.24 % respectively. This research was concluded that PTU treatment cannot alter absorption, distribution and elimination half time Na131I, but the accumulation in thyroid was decrease in A group to control.
America's first century of marine national park stewardship
Authors: Davis Gary E. , Kimball Dan B. 
Published: October 2017

ABSTRACT
A review of coastal national park stewardship reveals a rich history that provides evidence of how nature and human history shaped current conditions along America's coasts. Case studies of Dry Tortugas National Park and Everglades National Park in Florida, and Channel Islands National Park in California exemplify how such experiences can help identify future directions and challenges for protecting coastal areas. Discoveries include (1) ecological and political borders are often incompatible because shorelines are ineffective ecological boundaries, (2) scales of protection are critical for management efficacy, (3) forging effective management solutions requires strategic, innovative public involvement, and (4) misperceptions of connectivity, sustainability, and relevance impair effective coastal conservation. This history and these stewardship experiences also demonstrated the potential power of protected areas to halt shifting ecological and moral baselines, thereby defining realistic imagination and hope for the future. Learning from national park experiences how to understand ecosystems, how to repair damage to their integrity, how to protect and mitigate human stresses to them, and how to better connect people to these special places has not only improved the condition of nature and human heritage in parks, but also has enhanced society's capacity to improve the human condition more broadly with small, but critical success stories.
Understanding and preserving caves and karst landscapes
Authors: Pate Dale L. , Kerbo Ronal C. 
Published: October 2017

ABSTRACT
Beginning in 1903 with the creation of Wind Cave National Park, ten National Park Service units have been created because of the caves they contained. Since the establishment of the National Park Service in 1916, over 5,360 caves are known to exist within at least 99 park units. These caves are found in different types of rocks and were formed by several different mechanisms. The most prolific landscapes that have formed caves are those in soluble rocks such as limestone. Known as karst landscapes, at least 114 park units contain some amount of karst. In the early days, cave parks were developed for their commercial and recreational values. Little was known of the processes that created caves or the many resources that encompassed these entire landscapes. With the help of cave and karst enthusiasts and researchers, and the advent of cave and karst resource managers, the National Park Service has made great strides in understanding these resources. This has led to increased educational opportunities and better management decisions that will enhance long-term preservation of these resources.

Published: October 2017

Background: Scabies is highly prevalent in children less than 6 years and more so in less than 2 years of age. Treating scabies in infants and children is challenging. The objective was to study the characteristics and distribution of lesions and outcome with topical Permethrin and Oral Ivermectin in scabies in children.Methods: 264 cases of scabies from the skin and pediatric outpatient of a tertiary care center were enrolled.Results: It is common in children below 5 years of age. The effectiveness of local Permethrin and oral Ivermectin was not significantly different in the form of complete cure.Conclusions: Children tend to scratch the rash repeatedly, the scratch marks and crusting of the rash sometimes make this infection hard to identify, hence high index of suspicion is required to diagnose. Complicated lesions in scabies require more duration than uncomplicated lesions. Permethrin and Ivermectin are equally effective in scabies. Ivermectin being orally administered is a drug of choice in epidemics.

A qualidade da água vem sofrendo alterações de ordem ambiental, social e econômica. Existem variáveis que classificam tal recurso como de melhor ou pior qualidade, sendo a de pior consequência de diversos problemas ambientais, que podem ser atribuídos tanto à ação antrópica, como despejo de efluentes doméstico, lançamento de resíduos sólidos, ocupações indevidas, quanto às mudanças que vem ocorrendo naturalmente no Meio Ambiente, como alterações na temperatura da água devido as condições climáticas, que em sua grande maioria estão indiretamente relacionadas com essas ações. Deste modo torna-se imprescindível a avaliação das características físicas, químicas e microbiológicas da água. Desta forma o presente trabalho buscou avaliar a qualidade da água da microbacia do Córrego Gumitá para verificar o seu enquadramento na legislação vigente, bem como avaliar os possíveis impactos causados e suas respectivas causas. Os resultados obtidos, mostraram que as águas sofrem impactos resultantes do lançamento de efluentes domésticos não tratados bem como de resíduos sólidos despejados pela população urbana que reside em suas margens. Levou-se em consideração análises de características físicas, químicas e microbiológicas no período chuvoso, sendo estas comparadas com os valores obtidos no período de seca e ainda com os padrões estabelecidos pelas Resoluções nº 357/2005 e nº 430/2011 do CONAMA. Encontraram-se em desacordo com a legislação vigente as variáveis físicas, cor e turbidez; as variáveis químicas pH, DBO e óleos e graxas e as variáveis microbiológicas, coliformes totais e termotolerantes.

High-resolution characterization of labile phosphorus, iron, and manganese in sediments of different trophic waters in Lake Taihu, China
Authors: Zeng Liqing , Yang Fan , Yan Changzhou , Wang Xinhong 
Published: October 2017

Abstract
High-resolution combined ZrO-Chelex diffusive gradients in thin film (DGT) probes were arranged to synchronously monitor the characteristics of labile phosphorus (P), iron (Fe), and manganese (Mn) in sediments from regions of varying trophic levels in Lake Taihu, China. Results showed that P release was closely related to the lake region's trophic level. Labile P in sediments and the apparent diffusion flux (Fd) of P were higher in hyper-eutrophic algae-dominated regions than those in macrophyte-algae-dominated and macrophyte-dominated regions, indicating that P released from sediments may be facilitated in eutrophic environments. A positive correlation observed between DGT-labile P and Fe or Mn, which had similar regional spatial distributions to P, showed that reductive dissolution of Fe-Mn (oxyhydr)oxides (FeOOH-MnOOH) in sediments was responsible for internal P release, which was strengthened in eutrophic environments. Ratios of labile Fe or Mn/labile P (LFe/LP and LMn/LP) in sediments in algae-dominated regions showed lower values than those in macrophyte-algae-dominated and macrophyte-dominated regions, further confirming that FeOOH-MnOOH in algae-dominated regions were less able to fix P, which brought higher pollution risks for the overlying water. LFe/LP or LMn/LP also had a significantly positive correlation with Fd, further testament that labile Fe or Mn was much more relevant to the sediment P cycle.
