Optically Controlled Abnormal Photovoltaic Current Modulation with Temperature in BiFeO3
Authors: Zhao Rudai , Ma Nan , Qi Jia , Mishra Yogendra Kumar , Adelung Rainer , Yang Ya 
Published: February 2019

AbstractFerroelectric materials hold great promise toward next generation of optoelectronic devices because of their unique characteristics such as above‐bandgap photovoltage and polarization‐dependent photocurrent. But the relative low photocurrent value limits their potential applications in real devices. In order to improve the photovoltaic performance and detailed and systematic investigations about the role of temperature gradient on the photocurrent in indium tin oxide (ITO)/BiFeO3 (BFO)/ITO device under various temperature gradients across both sides are carried out. The observed results reveal an enhancement in photocurrent under applying different temperature gradients, which is mainly associated with light intensity. The applied temperature gradients induce interesting mechanisms under weak and strong lights. Due to the temperature gradient controlled photocurrent, the photosensing performance of ITO/BFO/ITO photodetector device with respect to 365 nm light can be strongly modulated. This presented strategy offers a feasible route for enhancing the photovoltaic performances of the BFO material based device, which offers the capability to push forward the practical applications of ferroelectric photovoltaic devices.
Testing the associations between leading and lagging indicators in a contractor safety pre‐qualification database
Authors: Manjourides Justin , Dennerlein Jack T. 
Published: February 2019

BackgroundSafety prequalification assessing contractors’ safety management systems and safety programs lack validation in predicting construction worker injuries.MethodsSafety assessments of leading indicators from 2198 construction contractors, including Safety Management Systems (SMS), Safety Programs (e.g., falls, hearing protection), and Special Elements (drug testing, return to work) scales as well as the history of citations from the Occupational Safety and Health Administration (OSHA) were compared to contractors' lagging indicators of recordable injury case rates (RC) and rates of injuries involving days away, restricted, or transferred (DART).ResultsIncreased SMS scores were related to lower injury rates. Each one‐point increase in SMS values was associated with 34% reduced odds of a recordable case rate greater than zero (Odds ratio (OR): 0.66, 95% Confidence Interval (CI): (0.57, 0.79)), and a 9% reduced recordable case rate, if one occurs (Risk Ratio (RR): 0.91, 95% CI: (0.88, 0.94)). A one‐point increase in SMS was associated with 28% reduced odds of a DART (OR = 0.72, 95%CI (0.56, 0.91)), and 9% reduced DART rate, if one occurs (RR = 0.91, 95%CI (0.87, 0.95)). Safety programs did not show consistent associations with injury outcomes. Having additional Special Elements related to drug and alcohol programs was associated with lower injury rates while the Special Element related to return to work showed no consistent associations with injury. Having more OSHA Citations was associated with lower injury rates for companies with injuries.ConclusionsThese results support pre‐qualification methods based on SMS and suggest the need for safety management systems in contractors.
Removal of sulfur compounds from LPG by heteropoly acid‐modified spent FCC catalyst
Authors: Su Baochuan , Shi Li , Liu Naiwang , Wang Xin , Meng Xuan 
Published: February 2019

Modified spent FCC catalysts were prepared and the desulfurization properties of these adsorbents were examined in this paper. The experiment data indicated that the spent FCC catalyst performed well in desulfurization after modification; the sulfur content in the liquified petroleum gas (LPG) dropped down to 5~10 mg.m−3. X‐Ray Fluorescence, X‐ray diffraction, Nitrorms and Fourier transform infrared were applied to characterize these adsorbents. Results showed that the content of various metals in spent FCC catalyst was significantly higher than fresh catalyst; and the metals which deactivated the FCC catalysts became the active sites for desulfurization. In addition, a moderate amount of Lewis acid sites is advantageous to desulfurization while too many Lewis acid sites played a negative role.
Fully biobased polyester polyols derived from renewable resources toward preparation of polyurethane and their application for coatings
Authors: Khanderay Jitendra C. , Gite Vikas V. 
Published: February 2019

ABSTRACTRenewable resources such as isosorbide and dimer acid were used to prepare fully biobased polyester polyols and polyurethane (PU) coatings. The structural features of polyester polyols were studied by end‐group analysis and spectroscopic methods. Then polyols were utilized in the preparation of PU coatings by reacting with diisocyanate. The prepared PU coatings were tested for both mechanical and chemical testings, which involved gloss, cross‐cut adhesion, pencil hardness, anticorrosion performance by immersion and Tafel plot methods, and chemical resistance against water, solvent, and acid media. The prepared PUs were also tested for their thermal stability using a thermogravimetric analyzer and surface morphology by a scanning electron microscopy. Tested mechanical properties, chemical resistance, and thermal stability results demonstrated that the renewable sources used in the preparation of PU coatings can be good substitutes over petroleum resources. © 2019 Wiley Periodicals, Inc.

Authors: Martínez‐Marcos Alino , Sañudo José Ramón 
Published: February 2019

ABSTRACTThis Special Issue, entitled “Cranial Nerves: phylogeny, ontogeny, morphology and clinical significance,” has been divided into two consecutive volumes. We present here the first volume, devoted to phylogeny and ontogeny. Articles in this volume examine these two topics from a microscopic point of view. This volume includes an historical review that serves as an introduction. It also includes a review of the organization of cranial nerves from a neuromeric perspective which, together with two articles in amphioxi and lampreys, give emphasis to a comparative approach. Finally, several articles examine cranial nerves zero (nervus terminalis), I (olfactory), II (optic), III, IV and VI (oculomotor), VIII (cochlear and vestibular), and XI (accessory or spinal). Together, they provide a general overview of the neuroanatomical organization of cranial nerves, while offering insights into an evo‐devo paradigm.

Published: February 2019

AbstractRecently, Chinese medical education has exhibited a shifting trend from teacher‐centered instruction to student‐centered learning, which usually includes a self‐directed learning process. Providing students with high‐quality and appropriate supplemental resources is necessary for their self‐directed learning. This study aimed to investigate the appropriateness of AccessMedicine, an online medical resource, for first‐year medical students at Tongji University in China. In the randomized controlled trial, 42 students were stratified by gender and grade point average (GPA) and randomly assigned to either the control group or AccessMedicine group. The students' learning outcomes were assessed with quizzes, including tests before and after learning and a final examination. Paired t‐tests and two‐way analysis of variance were performed for statistical analysis. We found that AccessMedicine‐assisted learning improved student performance on tests and decreased the overall failure rate in the final examination. Further analysis showed that the final examination score of the subgroup with high GPAs in the AccessMedicine group significantly increased, but not that of the subgroup with low GPAs, indicating that AccessMedicine‐assisted learning was more beneficial for good students than for poor students. A survey showed that professional vocabularies were the greatest obstacles to learning with AccessMedicine. Moreover, English language skills greatly affected the students' learning outcomes for the English resource but not those for the Chinese resource. Taken together, our results demonstrated that AccessMedicine was appropriate for Chinese medical education and improved the learning outcomes of students, especially students with high GPAs and a good command over the English language. © 2019 International Union of Biochemistry and Molecular Biology, 47(3):272–278, 2019.

AbstractPropolis samples from north‐west Argentina (Amaicha del Valle, Tucumán) were evaluated by palynology, FT‐IR spectra, and RP‐HPTLC. In addition, the volatile fraction was studied by HS‐SPME‐GC/MS. The botanical species most visited by Apis mellifera L. near the apiaries were collected and their RP‐HPTLC extracts profiles were compared with propolis samples. In addition, GC/MS was performed for volatile compounds from Zuccagnia punctata Cav. (Fabaceae). FT‐IR spectra and RP‐HPTLC fingerprints of propolis samples showed similar profiles. In RP‐HPTLC analyses, only Z. punctata presented a similar fingerprint to Amaicha propolis. The major volatile compounds present in both were trans‐linalool oxide (furanoid), 6‐camphenone, linalool, trans‐pinocarveol, p‐cymen‐8‐ol, and 2,3,6‐trimethylbenzaldehyde. Potential variations for the Amaicha del Valle propolis volatile fraction as consequence of propolis sample preparation were demonstrated.

Published: February 2019

AbstractReactions involved in photocatalytic hydrogen production through water splitting combined with a hole scavenger involve several stages that make kinetic analysis quite complicated. In the present work, a kinetic model for the photocatalytic production of hydrogen has been developed based on competitive adsorption, considering the photocatalytic decomposition of an organic molecule coupled to hydrolysis through photocatalytic water splitting. Parameter estimation is performed by using the Levenberg‐Marquardt method. Model validation results give an estimation of the strength of adsorption of acetol and the acetaldehyde.
Electrodialysis Application of the Ultrafiltration Permeate of Milk Before and After Reverse Osmosis
Authors: Shakhno Nikolay , Botvynko Alina , Ečer Jiří , Čurda Ladislav 
Published: February 2019

AbstractUltrafiltered (UF) milk permeate was concentrated by reverse osmosis (RO). UF and UF + RO samples were then desalted by electrodialysis (ED) to three levels of desalination: 1, 2.5, and 4 % of ash in the dry matter. Ions were analyzed by a new high‐performance liquid chromatography method, which enables simultaneous estimation of cations and anions. ED of UF permeate has some advantages over that of UF + RO samples, including a shorter ED time and a higher average salt flow rate, but RO treatment of UF permeate before ED enables the processing of larger volumes of UF permeate. Therefore, ED of milk permeate, particularly after RO, improves the handling characteristics and may offer advantages for further processing of secondary dairy products.

Authors: Kossov Vladimir , Fedorenko Olga , Zhakebayev Dauren 
Published: February 2019

AbstractThe features characterizing the transition from a diffusion process to the concentration gravitational convection in multicomponent gas mixtures containing hydrocarbon components are analyzed. It is demonstrated that this transition is possible due to the difference in interdiffusion coefficients of components, initial concentration of components, and the pressure of the experiment. A mathematical model for describing the transition from the diffusion process to the concentration gravitational convection in multicomponent gas mixtures is considered. The key feature indicating the transfer from the diffusion regime to the convective one is the curvature of an isoline of the heavy component of the gas mixture.

AbstractHerein we report the photo‐ and electrochemical characterization of pyrimidopteridine N‐oxide‐based heterocycles. The potential of their application as organic photoredox catalysts is showcased in the photomediated contra‐thermodynamic E→Z isomerization of cinnamic acid derivatives and oxidative cyclization of 2‐phenyl benzoic acid to benzocoumarin using molecular oxygen as a mild oxidant. Furthermore, unprecedented intermolecular non‐covalent n–π‐hole interactions in solid state are discussed based on crystallographic and theoretical data.

Published: February 2019

AbstractThe Lewis acid B(C6F5)3 and the cyclic silane (ArN2Si)3 (1) (ArN=o‐(CH3)2NCH2C6H4) are useful precursors to access the silylene(II)–borane adduct ArN2Si‐B(C6F5)3 (2). Treatment of 2 with water led to coordination and gave the Lewis pair (ArN2H2O)Si‐B(C6F5)3 (3) that exhibits a hydrogen‐bond‐stabilized silanol unit. It can be converted into the siloxane [(HArN)2SiOB(C6F5)3]2O (6) by dehydrogenation in the presence of a base. Heteronuclear NMR spectroscopic data to characterize the compounds were supported by quantum‐chemical calculations.

AbstractA series of hybrid compounds based on natural products—bile acids and dihydroartemisinin—were prepared by different synthetic methodologies and investigated for their in vitro biological activity against HL‐60 leukemia and HepG2 hepatocellular carcinoma cell lines. Most of these hybrids presented significantly improved antiproliferative activities with respect to dihydroartemisinin and the parent bile acid. The two most potent hybrids of the series exhibited a 10.5‐ and 15.4‐fold increase in cytotoxic activity respect to dihydroartemisinin alone in HL‐60 and HepG2 cells, respectively. Strong evidence that an ursodeoxycholic acid hybrid induced apoptosis was obtained by flow cytometric analysis and western blot analysis.
Visualization of Trigeminal Ganglion Neuronal Activities in Mice
Authors: Hu Minghan 
Published: February 2019

AbstractVisualization of dynamic cellular activity has greatly expanded our understanding of brain function. Recently, there has been an increasing number of studies imaging rodent brain activity in real time. However, traditional in vivo calcium imaging technology has been limited to superficial brain structures. Because the trigeminal ganglion (TG) is located deep within the cranial cavity of mice, few studies have been able to access to it. To circumvent this limitation, overlying brain tissue must be removed to expose the TG so that optical recording can access deep brain neural ensembles. This unit describes a procedure for conducting non‐survival surgery to visualize the TG in live mice. Obtaining large ensembles of direct, real‐time readouts of sensory neuron signaling, providing temporal and spatial information across the TG, will help to define the cellular basis of orofacial somatic sensing and pain perception. © 2019 by John Wiley & Sons, Inc.
Anti‐neuroinflammatory effects of tannic acid against lipopolysaccharide‐induced BV2 microglial cells via inhibition of NF‐κB activation
Authors: Wu Yan , Zhong Lianmei , Yu Zeran , Qi Junhui 
Published: February 2019

AbstractMicroglia mediated neuroinflammation is known to cause various neurodegenerative and neurological ailments. Tannic acid is a natural polyphenol which has been reported to possess antioxidant, anti‐inflammatory, anticarcinogenic, antimutagenic, antitumor, and antimicrobial activities. As there are no reports till date on the anti‐neuroinflammatory effects of tannic acid, this study was conducted to analyze the possible mechanism and pathway involved in the prevention of neuroinflammation by tannic acid in BV2 microglial cells. BV2 microglial cells were pretreated with tannic acid (10, 25, and 50 μM/mL) and induced with lipopolysaccharide (LPS; 1 μM/mL) to assess the production of reactive oxygen species (ROS), nitric oxide (NO), prostaglandin E2 (PGE2), pro‐inflammatory cytokines (IL‐6, IL‐1β, and TNF‐α), and nuclear factor‐kappa B (NF‐κB) protein expressions through western blotting. The results showed that LPS significantly activated the BV2 cells via toll‐like receptor 4 to induce elevated productions of ROS, NO, PGE2, IL‐6, and IL‐1β. However, tannic acid was able to reverse all the neuroinflammatory effects of LPS‐induced BV2 cells in a dose‐dependent manner. Collectively, the anti‐inflammatory effects of tannic acid on LPS‐induced BV2 microglial cells are attributed to the inhibition of ROS formation and the suppression of NF‐κB pathway activation. Tannic acid could be a potential therapeutic agent for the treatment of neurological related disorders.
Wild boar (Sus scrofa) increases species diversity of semidry grassland: Field experiment with simulated soil disturbances
Authors: Horčičková Eva , Brůna Josef , Vojta Jaroslav 
Published: February 2019

AbstractBackgroundForaging activities of wild boar (Sus scrofa) create small‐scale soil disturbances in many different vegetation types. Rooting alters species composition by opening niches for less‐competitive plants and, as a recurrent factor, becomes a part of the community disturbance regime. Vegetation responses to wild boar disturbance have mostly been studied in the boar's non‐native range or in native forest, rather than in open habitats in the native range. We investigate the response of open European semidry grassland vegetation dominated by Brachypodium pinnatum to native wild boar pressure in an abandoned agricultural landscape.MethodsTo describe the disturbance regime, we repeatedly mapped rooted patches during a 5‐year period. Additionally, to study the vegetation response, we performed an artificial disturbance experiment by creating 30 pairs of simulated disturbances and undisturbed plots. The vegetation composition of the paired plots was repeatedly sampled five times in eight years of the study.ResultsBased on repeated mapping of disturbances, we predict that if the disturbance regime we observed during the 5‐year period were maintained over the long term, it would yield a stable vegetation ratio consisting of 98.7% of the grassland undisturbed, 0.4% with fresh disturbance, and 0.9% in older successional stages.Vegetation composition in the artificially disturbed plots was continuously converging to that of undisturbed vegetation, but these disturbed plots still differed significantly in composition and had higher species number, even after eight years of succession.SynthesisOur results thus show that wild boar disturbance regime in its native range increases heterogeneity and species diversity of semidry grassland vegetation.

Self‐referenced interpersonal similarity phenomena: Theoretical specification and assessment at the individual, dyadic and group levels
Authors: Malloy Thomas E. 
Published: February 2019

AbstractA basic interpersonal task is assessing if another is similar to oneself, and is even observed among prelinguistic infants. In 450 highly acquainted dyads (150 from family, friend, co‐worker groups), participants judged others' similarity to themselves, and predicted others' similarity ratings of them. Assumed reciprocity and reciprocity of similarity judgments were observed; the former was much stronger than the latter. Specific others were judged as uniquely similar; in families these judgments were reciprocated. People inaccurately predicted others', and specific others', similarity judgments. Common members of these groups (key person) judged others as similar to themselves, and predicted others' reciprocated similarity judgments, although they did not. Social relations modeling showed that interpersonal similarity assessments in different groups are multiple phenomena at multiple levels of analysis and should not be treated as a single, unitary phenomenon.
