Published: November 2019

Lead pacemaker infection is a complication on the rise. An infected oscillating mass attached to the leads (ILV) is a common finding in this setting. Percutaneous extraction of the leads and of the device is the best curative option. However, extraction of leads with large masses can be complicated by pulmonary embolism. The aim of this study was to understand the factors associated with large ILV using a sophisticated ultrasound technique to visualize the masses, namely intracardiac echocardiography (ICE), and investigate whether larger masses induce more complications during and after extraction. Percutaneous lead extraction and peri-procedural ICE were done in 36 patients (pts) (75 ± 11 years old, 74% males). Vegetations (max dimension = 8.2 ± 4.1 mm) in the right cavity were found in 26 of them, mostly adhering to the leads. We subdivided the patients into 2 groups: with vegetation size < 1 cm (18 pts) and vegetation size ≥ 1 cm (8 pts). By univariate analysis, we found that patients in group 1 were more often taking anticoagulation therapy (p = 0.03, Phi (Phi coefficient) = −0.5, OR [odds ratio] 0.071) and had signs of local pocket infection (p = 0.02, Phi = −0.52, OR 0.059) while significantly more patients in group 2 had diabetes (p = 0.08, Phi = 0.566, OR 15); moreover the patients in group 2 showed a trend toward a more frequent positive blood culture (p = 0.08, Phi = 0.39, OR 5.8) and infection with coagulase negative staphylococci (p = 0.06, Phi = 0.46, OR 8.3). At multivariate analysis, only 3 factors (diabetes, younger age and anticoagulation therapy) were independently associated with ILV size: diabetes, associated with larger vegetations (group 2), showed the largest beta value (0.44, p = 0.008); age was inversely correlated with ILV size (beta value = −32, p = 0.038), and anticoagulation therapy (beta value = −029, p = 0.048) was more commonly associated with smaller vegetations (group 1). Larger ILV were not associated with more complications or death during or after the extraction. Conclusion: diabetes, anticoagulation therapy and age are independent predictors of lead vegetation size. The embolic potential of large ILV during extraction was modest, so ILVs >1cm are not a contraindication to percutaneous extraction of infected leads.

Authors: Kawaguchi Genta , Yamamoto Hiroshi
Published: November 2019

A new superconducting field-effect transistor (FET) in the vicinity of bandwidth-controlled Mott transition was developed using molecular strongly correlated system κ-(BEDT-TTF)2Cu[N(CN)2]Br [BEDT-TTF = bis(ethylenedithio)tetrathiafulvalene] laminated on CaF2 substrate. This device exhibited significant cooling-rate dependence of resistance below about 80 K, associated with glass transition of terminal ethylene group of BEDT-TTF molecule, where more rapid cooling through glass transition temperature leads to the decrease in bandwidth. We demonstrated that the FET properties such as ON/OFF ratio and polarity can be controlled by utilizing cooling rate. Our result may give a novel insight into the design of molecule-based functional devices.

Published: November 2019

Dead wood comprises a vast amount of biological legacies that set the scene for ecological regeneration after wildfires, yet its removal is the most frequent management strategy worldwide. Soil-dwelling organisms are conspicuous, and they provide essential ecosystem functions, but their possible affection by different post-fire management strategies has so far been neglected. We analyzed the abundance, richness, and composition of belowground macroarthropod communities under two contrasting dead-wood management regimes after a large wildfire in the Sierra Nevada Natural and National Park (Southeast Spain). Two plots at different elevation were established, each containing three replicates of two experimental treatments: partial cut, where trees were cut and their branches lopped off and left over the ground, and salvage logging, where all the trees were cut, logs were piled, branches were mechanically masticated, and slash was spread on the ground. Ten years after the application of the treatments, soil cores were extracted from two types of microhabitat created by these treatments: bare-soil (in both treatments) and under-logs (in the partial cut treatment only). Soil macroarthropod assemblages were dominated by Hemiptera and Hymenoptera (mostly ants) and were more abundant and richer in the lowest plot. The differences between dead-wood treatments were most evident at the scale of management interventions: abundance and richness were lowest after salvage logging, even under similar microhabitats (bare-soil). However, there were no significant differences between microhabitat types on abundance and richness within the partial cut treatment. Higher abundance and richness in the partial cut treatment likely resulted from higher resource availability and higher plant diversity after natural regeneration. Our results suggest that belowground macroarthropod communities are sensitive to the manipulation of dead-wood legacies and that management through salvage logging could reduce soil macroarthropod recuperation compared to other treatments with less intense management even a decade after application.

Published: November 2019

Polysaccharides are an important class of bioactive components of medical mushroom and herbs and are now used as natural drugs or dietary supplements on a global scale. In this paper, we aimed to increase the polysaccharide production of Cordyceps militaris and the antioxidant activities of fermented rice by solid-state fermentation. The media components and culture condition were optimized by orthogonal design and mono-factor tests using rice as the raw material. The optimal media consisted of (g/L): rice (50), fructose (7), glycerin (7), peptone (1), MgCl2 (0.11), VB1 (0.05), VB2 (0.05), CaCl2 (1.5), corn bran (6), and a water–materials ratio of 100%. The fermentation condition was as follows: inoculum volume of 5.5% (v/w), rice weight of 50 g in one bowl with a diameter of 120 mm and a depth of 90 mm, incubation temperature of 26 °C, and incubation time of seven days. Under the optimized condition, the maximal C. militaris polysaccharide content and free radical scavenging ratio were 68.3 mg/g dry substrate and 98.9%, respectively. This study provides a new strategy for the production of healthy food from traditional food.

Published: November 2019

Whole grain quinoa and wheat, high-protein vegetable flatbreads were evaluated by tasters and a physical analysis was conducted. The objective was to produce nutritious, tasty gluten-free (quinoa) as well as gluten-containing (wheat) flatbreads. Flatbreads were Quinoa Peanut Oilcake Broccoli (QPCBROC), Wheat Peanut Oilcake Broccoli (WPCBROC), Quinoa Peanut Oilcake Beets (QPCBEET) and Wheat Peanut Oilcake Beets (WPCBEET). Peanut Oilcake would increase protein and add value to this farm byproduct. Bile acid binding broccoli and beets with cholesterol-lowering potential were used. Tasters preferred QPCBROC flatbreads for all sensory parameters. Acceptance of flatbreads was QPCBROC (83%), WPCBROC (70%), QPCBEET (78%) and WPCBEET (69%); these values were statistically similar. The objective of ≥25% protein content was exceeded by 5–8% and that of ≥70% acceptance was adequately achieved. These flatbreads were low in fat (5–6%) and contained essential minerals (4%) with only ≤1% added salt. Porosity and expansion data suggest that these flatbreads would take up relatively little shelf space. These flatbreads require only three ingredients and can be made in a household kitchen or by commercial production. These flatbreads offer a nutritious, tasty choice for all, and quinoa flatbreads offer an option for gluten-sensitive individuals.

Published: November 2019

Influence of the combined effect of ultra-sonication (US) and high-voltage cold plasma treatment (HVCP) on the quality parameters of fresh carrot juice has been studied. During the treatment of ultra-sonication, carrot juice was subjected to a 0.5 inch probe for 3 min by adjusting the pulse duration 5 s on and off at 20 kHz frequency, amplitude level 80%. The ultrasound intensity was measured by using a thermocouple and was 46 Wcm−2. The temperature was maintained at 10 °C by an automatic control unit. During the treatment of HVCP, carrot juice was then subjected to dielectric barrier discharge (DBD) plasma discharge at 70 kV voltage for 4 min. Significant increases were observed when HVCP treated carrot juice was tested against total carotenoids, lycopene, and lutein when compared to the control treatments. Moreover, this increase was raised to its highest in all pigments, chlorogenic acid, sugar contents, and mineral profile, as the results of ultra-sonication when combined with high voltage atmospheric cold plasma (US-HVCP). Whereas, a significant decreased was observed in Mg, total plate count, yeast, and mold after US-HVCP treatment. Furthermore, results indicated that the combined effect of US-HVCP treatment has improved the quality and led to a higher concentration of lycopene, lutein, chlorogenic acid, and mineral compounds (Na, K, and P). Therefore, the findings of the current study suggested that US-HVCP treatment is a novel combined technique that could provide better quality and more stability during the processing of carrot juice with better physicochemical properties and bio-available nutrients, so this novel processing technique could serve as an alternative to traditional processes.
Nutritional Knowledge and Self-Reported Nutritional Practice against Malnutrition among Physicians in Jeddah, Saudi Arabia
Authors: Alkhaldy Areej Ali
Published: November 2019

The new era of healthcare emphasizes the integration of nutritional care into healthcare management to improve patient outcomes. Previous studies indicated that nutritional knowledge among physicians is insufficient. Thus far, only a limited number of studies have assessed nutritional knowledge among Saudi physicians, without providing data regarding their views toward practice against malnutrition. Therefore, the aim of the present cross-sectional study was to address this knowledge gap among Saudi physicians in the hospitals of Jeddah, Saudi Arabia. A total of 117 physicians were recruited using a questionnaire to collect physician characteristics, nutritional knowledge, and knowledge and practice related to malnutrition. The mean nutritional knowledge scores were low (50%; SD: 24%). Saudi physicians scored high in questions related to the medical field; however, their knowledge related to nutrition topics was poor. The majority of Saudi physicians agreed that the nutritional management of malnourished patients was difficult at screening (79%), assessment (78%), and treatment (78%) stages. The self-assessed knowledge and interest of physicians toward malnutrition was modest, and they found the malnutrition management to be only moderately relevant to their work. Nutritional knowledge and practice against malnutrition among Saudi physicians is insufficient. Saudi physicians require proper education and training in nutrition.

Published: November 2019

Objectives: Exploring determinants underlying disparities in full vaccination coverage (FVC) can contribute to improved immunization interventions. FVC and its risk factors in Zhejiang province have been studied, yet the determinants explaining the rural–urban disparity in FVC have not been studied. This study aimed to disentangle the factors explaining rural–urban disparities in FVC of vaccine doses scheduled during the first year of life in Zhejiang province. Methods: We used data from a vaccination coverage survey among children aged 24–35 months conducted in 2016. The outcome measure was full vaccination status, and the grouping variable was the area of residence. Descriptive statistics were used to analyze the FVC and rural–urban residence across the exposure variables. The Fairlie decomposition technique was used to decompose factors contributing to explaining the FVC disparity. Results: There were 847 children included in this study, of which 49.6% lived in a rural area. FVC was 94% in rural areas and 85% in urban areas. A disparity of 9% to the advantage of the rural areas and the exposure variables explained 81.1% of the disparity. Maternal factors explained 49.7% of the explained disparity with education, occupation, and ethnicity being the significant contributors to the explained disparity. Children’s birth order and immigration status contributed somewhat to the explained inequality. Conclusion: There was a significant disparity in FVC in Zhejiang province, a disadvantage to the urban areas. Policy recommendations or health interventions to reduce the inequality should be focused on eliminating poverty and women’s illiteracy, targeted at migrant children or children from minority ethnicities.

Published: November 2019

The influences of different laser power density in LSP (laser shock peening) on the corrosion performance of biocompatible magnesium alloy ZK60 were researched via SBF (Simulated Body Fliud) immersion testing and electrochemical testing. Corrosion morphology and corrosion products were observed and analyzed using SEM (Scanning Electron Microscope) outfitted with EDS (Energy Dispersive Spectrometer) and XRD (X-ray Diffraction). Simultaneously, 3D morphology, surface roughness, residual stress, and microstructure were also characterized. Results reveal that the modified samples can obtain higher residual compressive stress, which can lead to lower degradation rates in SBF solution. In terms of the weight loss of the samples, corrosion resistance increased by 52.1% maximally. The corrosion potential of modified samples in the SBF solution positively shifted from −1.3884 V to −1.1094 V and the corrosion current density decreased by 13.2% at most. The anti-corrosion ability of ZK60 is significantly enhanced by the LSP process.

Published: November 2019

Life in salt pans with varying chemical compositions require special adaptation strategies at both the physiological and molecular level. The Marakkanam salt pan in South India is characterized with a high fluctuation in salinity (19–490 ppt), Ultravioletradiation, and heavy metal concentrations. Several bacterial species have been isolated and identified in the view of phylogenetic analysis and for the subsequent production of industrially important enzymes. However, limited information exists on the genomic basis of their survival under variable environmental conditions. To this extent, we sequenced the whole genome of the Salinivibrio sp. HTSP, a moderately halophilic bacterium. We analysed the physiological and genomic attributes of Salinivibrio sp. HTSP to elucidate the strategies of adaptation under various abiotic stresses. The genome size is estimated to be 3.39 Mbp with a mean G + C content of 50.6%, including 3150 coding sequences. The genome possessed osmotic stress-related coding sequences, and genes involved in different pathways of DNA repair mechanisms and genes related to the resistance to toxic metals were identified. The periplasmic stress response genes and genes of different oxidative stress mechanisms were also identified. The tolerance capacity of the bacterial isolates to heavy metals, UV-radiation, and salinity was also confirmed through appropriate laboratory experiments under controlled conditions.
Origin of the Shangfang Tungsten Deposit in the Fujian Province of Southeast China: Evidence from Scheelite Sm–Nd Geochronology, H–O Isotopes and Fluid Inclusions Studies
Authors: Zhu Lü-Yun , Jiang Shao-Yong , Chen Run-Sheng , Ma Ying
Published: November 2019

The Shangfang deposit is a recently discovered large-scale tungsten deposit (66,500 t at 0.23% WO3), which is located near the western boundary of the Southeastern Coastal Metallogenic Belt (i.e., Zhenghe–Dafu fault), and adjacent to the northeast of the Nanling Range Metallogenic Belt. Unlike many other W–Sn deposits in this region that occur within or near the granites, the orebodies in the Sangfang deposit all occur within the amphibolite of Palaeoproterozoic Dajinshan Formation and have no direct contact to the granite. In this study, we carry out a thermal ionization mass spectrometer (TIMS) Sm-Nd isotope analysis for the scheelites from the orebody, which yields a Sm–Nd isochron age of 157.9 ± 6.7 Ma (MSWD = 0.96). This age is in good agreement with the previously published zircon U–Pb age (158.8 ± 1.6 Ma) for the granite and the molybdenite Re–Os age (158.1 ± 5.4 Ma) in the deposit. Previous studies demonstrated that the W–Sn deposits occurring between Southeastern Nanling Range and Coastal Metallogenic Belt mainly formed in the two periods of 160–150 Ma and 140–135 Ma, respectively. The microthermometry results of fluid inclusions in scheelite and quartz are suggestive of a near-isothermal (possibly poly-baric) mixing between two fluids of differing salinities. The H–O isotope results illustrate that the ore-forming fluids are derived from magma and might be equilibrated with metamorphic rocks at high temperature. The Jurassic granite pluton should play a critical role for the large hydrothermal system producing the Shangfang W deposit. Furthermore, the negative εNd(t) of −14.6 obtained in the Shanfang scheelite suggests for the involvement of the deep crustal materials. In general, subduction of the paleo-Pacific plate caused an extensional tectonic setting with formation of the Shangfang granites and related W mineralization, the geological background of which is similar to other W deposits in the Nanling Range Metallogenic Belt.

Published: November 2019

To discover novel potent cytotoxic diterpenoids, a series of hybrids of dehydroabietic acid containing 1,2,3-triazole moiety were designed and synthesized. The target compounds were characterized by means of FT-IR, 1H NMR, 13C NMR, ESI-MS and elemental analysis techniques. The in vitro cytotoxicity of these compounds was evaluated by standard MTT (methyl thiazolytetrazolium) assay against CNE-2 (nasopharynx), HepG2 (liver), HeLa (epithelial cervical), BEL-7402 (liver) human carcinoma cell lines and human normal liver cell (HL-7702). The screening results revealed that most of the hybrids showed significantly improved cytotoxicity over parent compound DHAA. Among them, [1-(3-fluorobenzyl)-1H-1,2,3-triazole-4-yl]dehydroabietic acid methyl ester (3c), and [1-(2-nitrobenzyl)-1H-1,2,3-triazole-4-yl]dehydroabietic acid methyl ester (3k) displayed better antiproliferative activity with IC50 (50% inhibitory concentration) values of 5.90 ± 0.41 and 6.25 ± 0.37 µM toward HepG2 cells compared to cisplatin, while they exhibited lower cytotoxicity against HL-7702. Therefore, the 1,2,3-triazole-hybrids could be a promising strategy for the synthesis of antitumor diterpenoids and it also proved the essential role of 1,2,3-triazole moiety of DHAA in the biological activity.
Valuable Fatty Acids in Bryophytes—Production, Biosynthesis, Analysis and Applications
Authors: Lu Yi , Eiriksson Finnur Freyr , Thorsteinsdóttir Margrét , Simonsen Henrik Toft
Published: November 2019

Bryophytes (mosses, liverworts and hornworts) often produce high amounts of very long-chain polyunsaturated fatty acids (vl-PUFAs) including arachidonic acid (AA, 20:4 Δ5,8,11,14) and eicosapentaenoic acid (EPA, 20:5 Δ5,8,11,14,17). The presence of vl-PUFAs is common for marine organisms such as algae, but rarely found in higher plants. This could indicate that bryophytes did not lose their marine origin completely when they landed into the non-aqueous environment. Vl-PUFA, especially the omega-3 fatty acid EPA, is essential in human diet for its benefits on healthy brain development and inflammation modulation. Recent studies are committed to finding new sources of vl-PUFAs instead of fish and algae oil. In this review, we summarize the fatty acid compositions and contents in the previous studies, as well as the approaches for qualification and quantification. We also conclude different approaches to enhance AA and EPA productions including biotic and abiotic stresses.

Published: November 2019

Targeted drug delivery systems are commonly used to improve the therapeutic index of anti-cancer drugs by increasing their selectivity and reducing systemic distribution and toxicity. Ligand-conjugated nanoparticles (NPs) can be effectively applied for active chemotherapeutic targeting to overexpressed receptors of tumor cells. In this study, transferrin (Tf) was successfully conjugated with poly-l-lactic-co-glycolic acid (PLGA) using ethylene diamine confirmed by NMR, for the loading of docetaxel trihydrate (DCT) into PLGA nanoparticles (NPs). The DCT-loaded Tf-conjugated PLGA NPs were produced by an emulsion-solvent evaporation technique, and a 32 full factorial design was used to optimize the nanoparticle formulations. The DCT-loaded Tf-conjugated PLGA NPs were characterized by FTIR spectroscopy, differential scanning calorimetry, powder X-ray diffraction (PXRD), TEM, particle size, and zeta potential analysis. In vitro release kinetics confirmed that release of DCT from the designed formulations followed a zero-order kinetics and a diffusion controlled non-Fickian release profile. The DCT-loaded Tf-conjugated PLGA NPs were evaluated in vitro in MCF-7 cells for bioactivity assessment. Cytotoxicity studies confirmed that the Tf-conjugated PLGA NPs were more active than the non-conjugated counterparts. Cell uptake studies re-confirmed the ligand-mediated active targeting of the formulated NPs. From the cell cycle analysis, the anti-cancer activity of DCT-loaded Tf-conjugated PLGA NPs was shown to occur by arresting the G2/M phase.

Published: November 2019

A xenon micro flow control device (XMFCD) is the key component of a xenon feeding system, which controls the required micro flow xenon (µg/s–mg/s) to electric thrusters. Traditional XMFCDs usually have large volume and weight in order to achieve ultra-high fluid resistance and have a long producing cycle and high processing cost. This paper proposes a miniaturized, easy-processing, and inexpensive XMFCD, which is fabricated by low-temperature co-fired ceramic (LTCC) technology. The design of the proposed XMFCD based on complex three-dimensional (3D) microfluidic channels is described, and its fabrication process based on LTCC is illustrated. The microfluidic channels of the fabricated single (9 mm diameter and 1.4 mm thickness) and dual (9 mm diameter and 2.4 mm thickness) XMFCDs were both checked by X-ray, which proved the LTCC method’s feasibility. A mathematical model of flow characteristics is established with the help of finite element analysis, and the model is validated by the experimental results of the single and dual XMFCDs. Based on the mathematical model, the influence of the structure parameters (diameter of orifice and width of the groove) on flow characteristics is investigated, which can guide the optimized design of the proposed XMFCD.
A Matter of Responsible Management from Higher Education Institutions
Authors: Roos Nicolas
Published: November 2019

Higher education institutions (HEIs) are influential social institutions which disseminate knowledge, promote innovation, and educate future decision-makers. The increasing awareness of HEIs as social actors has increased the pressure on them to accept and act upon their social responsibility. Processing this responsibility requires a structured management approach. The little attention given thus far to management performance and structured steering processes of social responsibility in HEIs marks the research gap the present study is focused on. This article provides a systematic review of scientific and academic publications, applying the concept of Social Performance after Wood (1991). The study aims to combine different research and modeling approaches to examine individual elements of social performance along the dimensions of processes of social responsiveness and outcomes of institutional behavior. With this approach, the study aims to answer the question of how HEIs assume their responsibilities as social institutions. The results show that observable outcomes of social behavior in the academic environment reflect a broad understanding of different approaches. By clustering the encoded literature into processes and outcomes, the study structures the fragmented body of research reflecting the various characteristics of the higher education sector.
Analysis of Coordinated Development of Energy and Environment in China’s Manufacturing Industry under Environmental Regulation: A Comparative Study of Sub-Industries
Authors: Cheng Manli , Shao Zhen , Yang Changhui , Tang Xiaoan
Published: November 2019

In order to explore the impact of environmental regulation on the coordinated development of energy and the environment with the background of governance transition, we propose a three-stage integrated approach and use the panel data of China’s manufacturing industry 27 sub-sectors during the period of 2006–2015. In the first stage, according to the environmental pollution intensity, the manufacturing industry is divided into heavily polluting industry, moderately polluting industry, and lightly polluting industry. The second stage is employed the slacks-based measure (SBM)-undesirable method to study the sub-industries’ green energy-environmental efficiency under different environmental pollution intensities. Besides, the dynamic changes of technical innovation and efficiency among different industries are analyzed through the Malmquist productivity index. For the purpose of investigating the transmission mechanism of the Porter’s hypothesis and exploring the compound effects of environmental regulation and governance transition on green development, in the third stage, we use the panel data analysis to conduct more in-depth research on the relationship between environmental regulation, governance transition, and technical innovation. Results show that the highest average green energy-environmental efficiency is lightly polluting industry, which is 0.52, followed by the heavily polluting industry at 0.40, and the lowest is the moderately polluting industry, which is 0.32. By decomposing total factor productivity, heavily polluting industry is at the forefront of technical innovation. Panel data analysis results indicate that investment in research and development and governance transition could promote the growth of total factor productivity for manufacturing.
Corporate Environmental Responsibility and Firm Information Risk: Evidence from the Korean Market
Authors: Choi Daeheon , Chung Chune Young , Kim Dongnyoung , Liu Chang
Published: November 2019

Despite the potential benefits of a firm’s corporate environmental commitment to its information environment, few empirical studies examine the relationship between corporate environmental responsibility (CER) and firm information risk in emerging markets. In such markets, better corporate transparency and less information asymmetry are becoming increasingly important owing to firms’ poor governance structures, the lack of protection for investors, the substantial participation of unsophisticated individual investors, and so on. Using a comprehensive sample of firms engaged in CER for the period from 2005 to 2016, we find that a firm’s CER score has a negative effect on measures of firm information risk in the emerging Korean market, which is characterized by poor corporate governance and a strong influence of owner–managers. Furthermore, our results show that the negative relationship between CER and information risk is more pronounced for firms with higher uncertainty (lower transparency). Thus, we conclude that CER enhances a firm’s information environment by reducing investors’ information risk.

Published: November 2019

The coastal sediments were considered to contain diverse phages playing important roles in driving biogeochemical cycles based on genetic analysis. However, till now, benthic phages in coastal sediments were very rarely isolated, which largely limits our understanding of their biological characteristics. Here, we describe a novel lytic phage (named Shewanella phage S0112) isolated from the coastal sediments of the Yellow Sea infecting a sediment bacterium of the genus Shewanella. The phage has a very high replication capability, with the burst size of ca. 1170 phage particles per infected cell, which is 5–10 times higher than that of most phages isolated before. Meanwhile, the latent period of this phage is relatively longer, which might ensure adequate time for phage replication. The phage has a double-stranded DNA genome comprising 62,286 bp with 102 ORFs, ca. 60% of which are functionally unknown. The expression products of 16 ORF genes, mainly structural proteins, were identified by LC-MS/MS analysis. Besides the general DNA metabolism and structure assembly genes in the phage genome, there is a cluster of auxiliary metabolic genes that may be involved in 7-cyano-7-deazaguanine (preQ0) biosynthesis. Meanwhile, a pyrophosphohydrolase (MazG) gene being considered as a regulator of programmed cell death or involving in host stringer responses is inserted in this gene cluster. Comparative genomic and phylogenetic analysis both revealed a great novelty of phage S0112. This study represents the first report of a benthic phage infecting Shewanella, which also sheds light on the phage–host interactions in coastal sediments.
Untargeted Metabolite Profiling for Screening Bioactive Compounds in Digestate of Manure under Anaerobic Digestion
Authors: Lu Jiaxin , Muhmood Atif , Czekała Wojciech , Mazurkiewicz Jakub , Dach Jacek , Dong Renjie
Published: November 2019

Untargeted metabolite profiling was performed on chicken manure (CHM), swine manure (SM), cattle manure (CM), and their respective digestate by XCMS coupled with MetaboAnalyst programs. Through global chemical profiling, the chemical characteristics of different digestates and types of manure were displayed during the anaerobic digestion (AD) process. As the feed for AD, CM had less easily-degradable organics, SM contained the least O-alkyls and anomerics of carbohydrates, and CHM exhibited relatively lower bio-stability. The derived metabolite pathways of different manure during the AD process were identified by MetaboAnalyst. Twelve, 8, and 5 metabolic pathways were affected by the AD process in CHM, SM, and CM, respectively. Furthermore, bioactive compounds of digestate were detected, such as amino acids (L-arginine, L-ornithine, L-cysteine, and L-aspartate), hormones (L-adrenaline, 19-hydroxy androstenedione, and estrone), alkaloids (tryptamine and N-methyltyramine), and vitamin B5, in different types of manure and their digestates. The combination of XCMS and MetaboAnalyst programs can be an effective strategy for metabolite profiling of manure and its anaerobic digestate under different situations.

Published: November 2019

Macrophytes are important structural attributes of freshwater ponds and wetlands, affecting zooplankton community composition. One of the best-known macrophytes in the world is Eichhornia crassipes, which, due to its high reproductive rate, can quickly occupy large areas of aquatic environments. However, there have been few assessments of the direct effect of this macrophyte, in the absence of predators, for tropical zooplankton communities. The aim of this study was to evaluate the influence of E. crassipes on microcrustacean community structure using species and functional diversity, the latter providing an important tool to evaluate the response to changes in resource availability along an environment gradient. We also evaluated which functional traits were favored when the structural niche offered by submerged parts of the macrophytes was present. We conducted a 30 day mesocosm experiment (117 m3) with and without the presence of floating macrophytes (Eichhornia crassipes) inserted along one edge of the mesocosms. Treatment effects on microcrustacean density and community structure using taxonomic and functional classification approaches were assessed. There was a positive association between macrophyte presence and microcrustacean diversity for both diversity types, showing that the presence of macrophytes enhanced the niche availability for the microcrustacean community, likely through changes to resource diversity through habitat structure provision. In the presence of macrophytes, the abundance of species with the following feeding traits increased: burrowing, benthic habitat preference, and herbivore–detritivore and omnivore–carnivore trophic groups. Results showed that the species capable of using the niche offered by submerged macrophyte structures had benthic traits, enabling their co-existence with species possessing primarily pelagic traits. Using a functional approach, our study demonstrated that Eichhornia crassipes can structure microcrustacean communities and promote diversity, likely via increased habitat diversity, which enables the co-existence of species possessing different adaptations to acquiring resources available in the environment.

Razvoj franjevačke opservancije od sabora u Konstanzu do kraja pontifikata Martina V.
Authors: Tolić Željko
Published: November 2019

Franjevačka opservancija, započeta u 14. stoljeću, nastavila se razvijati i u idućem stoljeću, unatoč raznim teškoćama na koje je nailazila. Ovaj je članak podijeljen u tri dijela. U prvom dijelu, naslovljenom „Razvoj franjevačke opservancije u 15. stoljeću“, autor govori o razvoju i širenju opservantskog pokreta u Italiji, kolijevci franjevačke opservancije, zatim u Francuskoj, gdje je imala drugačiji slijed, Španjolskoj te u drugim europskim zemljama. U drugom dijelu, koji nosi naslov „Pontifikat Martina V.“, autor iznosi okolnosti izbora pape Martina V. na ekumenskom saboru u Konstanzu, kao i njegov pontifikat koji je bio od velike važnosti za razvoj franjevačke opservancije. U trećem dijelu, naslovljenom „Generalni kapituli: od Mantove do Asiza“, autor se koncentrira na zbivanja unutar franjevačkog reda, osobito na generalne kapitule – u Mantovi, Forliu, Ferrari, Casale Monferrato i, poglavito Asizu – koji su se odvijali u razdoblju od završetka ekumenskog sabora u Konstanzu do kraja pontifikata Martina V., na kojima je opservantski pokret, s ulaskom u Red „četvorice stupova“ i uz podršku spomenutog pape, stjecao sve veći ugled, kako unutar Reda tako i diljem europskog kontinenta. Reforma i željeno jedinstvo, postignuti i s oduševljenjem prihvaćeni na generalnom kapitulu u Asizu, kratko su trajali.
Genetic Algorithms Applied to Fractional Polynomials for Power Selection: Application to Diabetes Data
Authors: NDABASHİNZE Barnabe , USTUNDAG SİRAY Gülesen , SCRUCCA Luca
Published: November 2019

Fractional polynomials are powerful statistic tools used in
multivariable building model to select relevant variables and their functional
form. This selection of variables, together with their corresponding power is
performed through a multivariable fractional polynomials (MFP) algorithm that
uses a closed test procedure, called function selection procedure (FSP), based
on the statistical significance level α. In this paper, Genetic algorithms,
which are stochastic search and optimization methods based on string
representation of candidate solutions and various operators such as selection,
crossover and mutation; reproducing genetic processes in nature, are used as
alternative to MFP algorithm to select powers in an extended set of real
numbers (to be specified) by minimizing the Bayesian Information Criteria
(BIC). A simulation study and an application to a real dataset are performed to
compare the two algorithms in many scenarios. Both algorithms perform quite
well in terms of mean square error with Genetic algorithms that yied a more
parsimonious model comparing to MFP Algorithm.
Slovenska župnija presvetega Srca Jezusovega v Barbertonu, Ohio, skozi zgodovino
Authors: Klemenčič Matjaž , Hazemali David , Hrženjak Matevž
Published: November 2019

V prispevku je obravnavana zgodovina slovenske etnične župnije presvetega Srca Jezusovega v Barbertonu, Ohio, ki so jo ustanovili tam živeči člani slovenske priseljenske skupnosti. Prispevek temelji na izčrpnem arhivskem gradivu clevelandske škofije in na znanstveni literaturi. Slovenska priseljenska skupnost v mestu Barberton, Ohio, je postala konec drugega desetletja 20. stoletja številčno in finančno dovolj močna, da je lahko podprla ustanovitev etnične župnije. V 85-letni zgodovini te barbertonske župnije je tamkajšnjim faranom uspelo zgraditi tri cerkve in župnijsko šolo, v župniji pa se je izmenjalo dvanajst duhovnikov; od tega jih je imelo enajst slovenske korenine. Župnija je bila skupaj s tamkajšnjim slovenskim narodnim domom središče slovenske narodnostne in kulturne dejavnosti v mestu. Z njeno pomočjo se je slovensko-ameriška skupnost v mestu obdržala do današnjih dni. Zaradi spremenjenih razmer – amerikanizacija potomcev tretje in četrte generacije – je župnija presvetega Srca Jezusovega začela izgubljati etnično naravo, v začetku 21. stoletja pa je ob združitvi s tamkajšnjo poljsko etnično župnijo prenehala obstajati. Takšno usodo posameznih etničnih župnij lahko zasledimo tudi v nekaterih drugih do sedaj raziskanih slovenskih naselbinah v ZDA.

Authors: Carvalho de Miranda da Silva Sonaly
Published: November 2019

O presente artigo baseia-se na investigação cujo tema é “A CoordenaçãoPedagógica como Espaço de Conquista e Formação”, pertencente a  Facultad de Humanidad y Artes Mención Ciencias de la Educación de la Universidad Nacional de Rosario. Trata de compreender quais são os elementos fundamentais presentes na coordenação pedagógica da escola que contribuem para que os sujeitos nela envolvidos possam adquirir saberes, numa perspectiva de aprimorar, alterar ou aprofundar o que se pretende alcançar, para melhor organização do trabalho pedagógico na escola e na sala de aula. Para isso, adotamos como pressupostos teórico-metodológicos a epistemologia qualitativa de González Rey e a Teoria Histórico-Cultural de Vygotsky. Trabalhamos com duas escolas públicas de ensino fundamental, uma anos iniciais e outra anos finais.A apreciação das informações nos possibilitou chegar a quatro elementos: 1) O Sujeito Professor: emoções e pensamentos; 2) As Relações: o coletivo e a liderança pedagógica; 3) A Escola: estrutura administrativa e organização pedagógica; 4) A Formação: conhecimento e saberes. Assim, pretendemos contribuir com conhecimentos que possibilitem proporcionar uma visão de coordenação pedagógica, como ferramenta de enriquecimento educacional, de formação continuada do professor e de construção deum projeto Político-Pedagógico, todos necessários para a concretização de uma educação de qualidade social.

Authors: Maldonado Fuentes Ana Carolina , Sandoval Rubilar Pedro Rodrigo , Rodríguez Alveal Francisco Enrique
Published: November 2019

El propósito de la presente investigación es dar cuenta de la evaluación de la comprensión lectora en estudiantes de Formación Inicial Docente, cuyo dominio constituye uno de los aprendizajes claves del currículum escolar chileno.Específicamente, se aborda la lectura a partir de la información verbal (monomodal) y verbal-icónica (multimodal) en un libro álbum, siguiendo el modelo interactivo de lectura. En el marco de un diseño cuantitativo complementado de técnicas cualitativas, se aplicó un instrumento de lápiz y papel a 46 estudiantes de Pedagogía en Educación Parvularia y Pedagogía en Educación Básica de una universidad del centro sur del Consejo de Rectores de Chile. Los hallazgos, en general, evidencian resultados descendidos en las dimensiones evaluadas, cuyas diferencias son significativas entre los grupos de Formación Inicial Docente. Asimismo, se observan discrepancias en la calidad de las argumentaciones entre los estudiantes, lo que motiva a reflexionar respecto de qué tan preparados se encuentran los futuros profesores para la enseñanza de la comprensión lectora en el contexto de la multimodalidad, por lo que se invita a una revisión de los modelos formativos en este ámbito.
PRÁCTICAS INCLUSIVAS EN EL NIVEL SECUNDARIO: LA EXPERIENCIA DESDE LA PERSPECTIVA DE UNA ESTUDIANTE CON DISCAPACIDAD
Authors: Dubrovsky Silvia , Lanza Carla
Published: November 2019

En el presente artículo se comparten algunos recortes de un proyecto de investigación cuyo propósito es indagar de qué modo se configuran las prácticas pedagógicas en el marco de lo que se ha denominado el paradigma de la inclusión, interpelando saberes, dispositivos y prácticas de la cultura institucional de las escuelas.Tomamos como marco conceptual los desarrollos Vigotskyanos en tanto se propusieron, en su época, superar los reduccionismos de la psicología tradicional, al reconocer la unidad de los procesos intelectuales y afectivos, el origen social y cultural de los procesos psicológicos superiores, y el carácter mediado de la mente y la actividad humana (Vigotsky, 1930; Castorina, 2002; Del Cueto, 2015).Este trabajo investiga, desde un enfoque etnográfico, el modo en que lasprácticas denominadas inclusivas influyen en el desarrollo de los/as alumnos/as “integrados/as”. Se toma para el análisis la perspectiva de una alumna “integrada” en relación a su experiencia escolar. Se propone el uso de la categoría perezhivanie como unidad de análisis para dar cuenta de la complejidad de las prácticas educativas en tanto el concepto relaciona los procesos y las leyes de desarrollo con el rol del ambiente social.
JUAN MANTOVANI: GESTIÓN EDUCATIVA Y POLÍTICA CULTURAL EN LA PROVINCIA DE SANTA FE (1938-1941)
Authors: Welti María Elisa , Guida María Eugenia , Semorile Claudia Inés
Published: November 2019

Analizamos la gestión del intelectual santafesino Juan Mantovani (San Justo, provincia de Santa Fe, 1898 - Alemania, 1961) entre 1938 y 1941como Ministro de Instrucción Pública y Fomento (en adelante MIPyF) de laprovincia de Santa Fe (Argentina) durante la gobernación del conservadorManuel de Iriondo (1937 - 1943). Mantovani impulsó en ese período un ambicioso programa tendiente a crear y consolidar instituciones culturales y de formación de artistas. Además, es conocido el apoyo brindado a Olga Cossettini que lo llevó a participar de diversas actividades realizadas por ella desde la dirección de la Escuela N° 69 “Dr. Gabriel Carrasco”.En este estudio consideramos como fuentes, los discursos de Juan Mantovani vinculados a su función ministerial, pronunciados y publicados en ese marco. Estos documentos ofrecen una vía de acceso a las ideas de Mantovani asociadas a la difusión de las artes y la cultura, en el despliegue de una política cultural, artística y educativa.Para el análisis aplicamos las claves metodológicas de la historia intelectual que permiten articular los rasgos de una política educativa más amplia con las líneas de los discursos que marcaron la trayectoria de Mantovani como funcionario, educador e intelectual, y su impronta en la definición de los campos pedagógico, artístico y cultural.
