OBJECTIVEThe cognitive deficits of vascular dementia and the vasoocclusive state of moyamoya disease have often been mimicked with bilateral stenosis/occlusion of the common carotid artery (CCA) or internal carotid artery. However, the cerebral blood flow (CBF) declines abruptly in these models after ligation of the CCA, which differs from “chronic” cerebral hypoperfusion. While some modified but time-consuming techniques have used staged occlusion of both CCAs, others used microcoils for CCA stenosis, producing an adverse effect on the arterial endothelium. Thus, the authors developed a new chronic cerebral hypoperfusion (CCH) model with cognitive impairment and a low mortality rate in rats.METHODSMale Sprague-Dawley rats were subjected to unilateral CCA occlusion and contralateral induction of CCA stenosis (modified CCA occlusion [mCCAO]) or a sham operation. Cortical regional CBF (rCBF) was measured using laser speckle flowmetry. Cognitive function was assessed using a Barnes circular maze (BCM). MRI studies were performed 4 weeks after the operation to evaluate cervical and intracranial arteries and parenchymal injury. Behavioral and histological studies were performed at 4 and 8 weeks after surgery.RESULTSThe mCCAO group revealed a gradual CBF reduction with a low mortality rate (2.3%). White matter degeneration was evident in the corpus callosum and corpus striatum. Although the cellular density declined in the hippocampus, MRI revealed no cerebral infarctions after mCCAO. Immunohistochemistry revealed upregulated inflammatory cells and angiogenesis in the hippocampus and cerebral cortex. Results of the BCM assessment indicated significant impairment in spatial learning and memory in the mCCAO group. Although some resolution of white matter injury was observed at 8 weeks, the animals still had cognitive impairment.CONCLUSIONSThe mCCAO is a straightforward method of producing a CCH model in rats. It is associated with a low mortality rate and could potentially be used to investigate vascular disease, moyamoya disease, and CCH. This model was verified for an extended time point of 8 weeks after surgery.

Published: September 2018

Penelitian ini bertujuan mengetahui proses pembuatan biodiesel dengan memanfaatkan limbah minyak jelantah serta mengetahui perbedaan penggunaan alat antara reaktor dan panci terhadap kualitas biodiesel. Saat ini ketersediaan minyak jelantah sangat banyak dan hanya dibuang tanpa dimanfaatkan. Minyak jelantah yang digunakan berasal dari limbah minyak goreng bekas minimal dua kali penggorengan.
Pembuatan biodiesel dari minyak jelantah dilakukan dengan proses transesterifikasi dengan dibantu katalis untuk mereaksikannya. Karena minyak jelantah yang dipakai sebagai penelitian hanya 2 kali penggorengan, maka kadar free fatty acids tersebut tidak banyak. Proses transesterifikasi dengan metanol memakai perbandingan antara sodium metoksida dan minyak jelantah. Waktu yang diperlukan untuk proses transesterifikasi adalah 60 menit dengan suhu konstan 65 0C. Alat pereaksi yang digunakan sebagai perbandingan yaitu antara reaktor labu leher tiga dengan panci stainless steel tertutup. Hasil penelitian menunjukkan bahwa tidak ada perbedaan yang nyata antara pembuatan biodiesel dengan menggunakan reaktor dengan menggunakan panci. Untuk hasil parameter biodiesel dengan menggunakan kedua alat tersebut juga tidak banyak berpengaruh terhadap kualitas biodiesel itu tersendiri.

Abstract
Among a number of active galactic nuclei that drive ionized outflows in X-rays, a low-redshift (z = 0.184) quasar, PDS 456, is long known to exhibit one of the exemplary ultra-fast outflows (UFOs). However, the physical process of acceleration mechanisms is yet to be definitively constrained. In this work, we model the variations of the Fe K UFO properties in PDS 456 over many epochs in X-ray observations in the context of magnetohydrodynamic (MHD) accretion disk winds employed in our earlier studies of similar X-ray absorbers. We applied the model to the 2013/2014 XMM-Newton/NuSTAR spectra to determine the UFO’s condition; namely, velocity, ionization parameter, column density, and equivalent width (EW). Under some provisions on the dependence of X-ray luminosity on the accretion rate applicable to near-Eddington state, our photoionization calculations, coupled to a 2.5-dimensional MHD-driven wind model, can further reproduce the observed correlations of the UFO velocity and the anticorrelation of its EW with the X-ray strength of PDS 456. This work demonstrates that UFOs, even without radiative pressure, can be driven as an extreme case purely by magnetic interaction while also producing the observed spectrum and correlations.
Diverse Protoplanetary Disk Morphology Produced by a Jupiter-mass Planet
Authors: Bae Jaehan , Pinilla Paola , Birnstiel Tilman 
Published: September 2018

Abstract
Combining hydrodynamic planet–disk interaction simulations with dust evolution models, we show that protoplanetary disks with a giant planet can reveal diverse morphology in (sub)millimeter continuum, including a full disk without significant radial structure, a transition disk with an inner cavity, a disk with a single gap and a central continuum peak, and a disk with multiple rings and gaps. Such diversity originates from (1) the level of viscous transport in the disk, which determines the number of gaps a planet can open; (2) the size and spatial distributions of grains determined by the coagulation, fragmentation, and radial drift, which in turn affects the emissivity of the disk at (sub)millimeter wavelengths; and (3) the angular resolution used to observe the disk. In particular, our results show that disks with the same underlying gas distribution can have very different grain size/spatial distributions and thus appearance in continuum, depending on the interplay among coagulation, fragmentation, and radial drift. This suggests that proper treatments for the grain growth have to be included in models of protoplanetary disks concerning continuum properties and that complementary molecular line observations are highly desired in addition to continuum observations to reveal the true nature of disks. The fact that a single planet can produce diverse disk morphology emphasizes the need to search for more direct, localized signatures of planets in order to confirm (or dispute) the planetary origin of observed ringed substructures.
Écrire ensemble : un défi au service de la construction d’une posture auctoriale
Authors: Raulet-Marcel Caroline 
Published: September 2018

Dans la perspective des programmes de 2015, l’article analyse un projet d’écriture collective mené durant l’année 2013-2014 en cycle 3 d’école primaire, en montrant en quoi certaines des récentes préconisations ministérielles entérinent le travail déjà engagé sur le terrain sous l’impulsion des recherches en didactique de l’écriture. Il s’agit d’insister tout particulièrement sur les enjeux et les modalités d’un dispositif peu détaillé dans les programmes : l’écriture collective. L’instauration d’une communauté de scripteurs est un puissant levier dans l’émergence d’une posture d’auteur collective et singulière. Le travail proposé aux élèves ouvre un espace de dialogue créatif et réflexif au sein de la classe, dialogue entre pairs mais aussi dialogue avec les œuvres littéraires. Les interactions suscitées par les phases de création collective rendent possible mais aussi visible un processus d’écriture-réécriture très riche, à travers lequel se révèle et se forge la conscience esthétique et stylistique des élèves.
Statistical Primer for Athletic Trainers: Understanding the Role of Statistical Power in Comparative Athletic Training Research
Authors: Lininger Monica R. , Riemann Bryan L. 
Published: September 2018

Objective: To describe the concept of statistical power as related to comparative interventions and how various factors, including sample size, affect statistical power.Background: Having a sufficiently sized sample for a study is necessary for an investigation to demonstrate that an effective treatment is statistically superior. Many researchers fail to conduct and report a priori sample-size estimates, which then makes it difficult to interpret nonsignificant results and causes the clinician to question the planning of the research design.Description: Statistical power is the probability of statistically detecting a treatment effect when one truly exists. The α level, a measure of differences between groups, the variability of the data, and the sample size all affect statistical power.Recommendations: Authors should conduct and provide the results of a priori sample-size estimations in the literature. This will assist clinicians in determining whether the lack of a statistically significant treatment effect is due to an underpowered study or to a treatment's actually having no effect.

Abstract. The aim of the study was to analyse the sex ratio of American mink litters in relation to dam's age, gestation length, and time interval between the first and second mating. The observations were carried out on a mink farm located in northern Poland. The analysis involved litters of 207 females, aged 1 (n=107) and 2 years (n=100), which successfully raised all the born kits. The sex of the offspring was identified on weaning. The kits were assigned to groups according to their dam's gestation length, mating date, and first-to-second mating interval. It was found that female kits quantitatively predominated over male offspring. Longer pregnancies, delayed mating time, and greater interval between the first and second mating was accompanied by a higher number of female births in relation to male births.

Essential oils from aromatic plants of Ledum palustre L. and Mentha piperita L. were extracted using steam distillation and the antimicrobial effects were evaluated alone and in combinations against food-borne pathogens of Gram-positive and Gram-negative bacteria and food related-yeasts (Bacillus subtilis, Escherichia coli, Saccharomyces cerevisiae, Schizosaccharomyce spombe, and Geotrichum candidum). Essential oils from two aromatic plants used in this study showed the antimicrobial activity against bacteria and yeast, which was found to be concentration dependent. The effects of Ledum palustre L. and Mentha piperita L. plants essential oils against yeast and Gram-negative bacteria at concentrations of 0.5 ul/ml and 0.25 ul/ml extended lag phase or adaptation phase by 48 hours, respectively. Gram-positive bacteria were found to be susceptible to the studied two plants essential oils. When the effects of antimicrobial activity of two essential oils were tested in combination against bacteria and yeast in vitro, the MIC value was in the range of 0.125-0.5 ul/ml and showed synergistic activity against E.coli and additive values against B.subtilis and S.cerevisiae.

Published: September 2018

AbstractColloidal quantum dots (QDs) have attracted scientific interest for infrared (IR) optoelectronic devices due to their bandgap tunability and the ease of fabrication on arbitrary substrates. In this work, short‐wave IR photodetectors based on lead sulfide (PbS) QDs with high detectivity and low dark current is demonstrated. Using a combination of time‐resolved photoluminescence, carrier transport, and capacitance–voltage measurements, it is proved that the charge carrier diffusion length in the QD layer is negligible such that only photogenerated charges in the space charge region can be collected. To maximize the carrier extraction, an optical model for PbS QD‐based photodiodes is developed, and through optical engineering, the cavity at the wavelength of choice is optimized. This universal optimization recipe is applied to detectors sensitive to wavelengths above 1.4 µm, leading to external quantum efficiency of 30% and specific detectivity (D*) in the range of 1012 Jones.

Published: September 2018

AbstractAdhesive hydrogels are promising to be explored as biomedical sealants, hemostatic agents, and glues in promoting wound healing and tissue regeneration. However, it is challenging to engineer a hydrogel combining instant robust adhesion and high strength. Herein, a high‐strength instantly self‐adhesive organic–inorganic hybrid (OIH) hydrogel by a one‐pot radical polymerization of N‐acryloyl 2‐glycine (ACG), biocompatible glycine derivative vinyl monomer with addition of hydroxyapatite (HAp), naturally occurring mineral is designed and fabricated. The hydrogen bonding from side chain of poly(N‐acryloyl 2‐glycine) (PACG), carboxyl‐Ca2+ ionic crosslinking together with PACG chain‐HAp physical interactions contribute to automatic self‐repairing high mechanical properties. Importantly, this OIH hydrogel exhibits robust adhesion to diverse substrates, presumably due to synergistic interactions of carboxyl with the substrate surface and the enhanced contact of PACG chains to adherent surfaces facilitated by HAp nanoparticles. Remarkably, the PACG‐HAp OIH hydrogels can instantly self‐adhere to the soft tissues with adhesion strength of 105 kPa, and anastomose the broken intestines, meanwhile promoting wound healing and stopping bleeding. The OIH hydrogel is autolytic in the body without eliciting inflammatory reaction. Further, the ready‐to‐use PACG‐HAp adhesive hydrogel can be properly stored for a long time. This novel hydrogel will find an appealing application as a new adhesive for emergency self‐rescue.
