Authors: Ferrari María-Aparecida , Durán Ana-María 
Published: November 2018

El presente texto presenta los resultados de investigación internacional realizada con empresas brasileñas y ecuatorianas con el objetivo de comparar prácticas de relaciones públicas en procesos de sustentabilidad. También se verificó la injerencia de las áreas de comunicación de las organizaciones de ambos países en los referidos procesos. Los resultados arrojados demuestran la importancia del departamento/área de comunicación para impulsar las prácticas de responsabilidad social y sustentabilidad, con el objetivo de aumentar la pertenencia de los empleados en las organizaciones, reforzar la identidad corporativa de las empresas, y facilitar que éstas estrechen lazos con los diferentes stakeholders. El estudio fue estructurado en tres etapas: revisión bibliográfica; investigación cuantitativa con encuestas a 177 responsables de comunicación de ambos países e investigación cualitativa con 18 entrevistas a profesionales seleccionados de la misma muestra. Los resultados indican que falta recorrer para que el proceso de sustentabilidad se afiance en las empresas y que el área de comunicación es esencial para impulsar prácticas de sustentabilidad, aumentar el sentido de pertenencia de los empleados, reforzar la identidad corporativa y estrechar lazos con los diferentes stakeholders.
Paid maternity leave extension and exclusive breastfeeding practice: evidence from Brunei
Authors: Alhaji Mohammed M. , Roslin Sharbawi , Kay Adrian , Tuah Nik A.A. 
Published: November 2018

Abstract

Background
Exclusive breastfeeding (EBF) of infants in their first 6 months postpartum is beneficial. However, maternal employment and short maternity leave impede EBF practice. In 2011, Brunei implemented a new Maternity Leave Regulation to extend paid maternity leave.

Objectives
To compare the prevalence of EBF between employed and nonworking mothers in Brunei, before and after extending paid maternity leave, to determine its effect on EBF and to determine the effects of maternal and infant sociodemographic characteristics.

Methods
Cross-sectional review of feeding records for infants born in 2010 (n = 6412, 85.5% all live births) and 2013 (n = 6680, 85.7%).

Results
EBF prevalence at 6 months postpartum increased from 29% in 2010 to 41% in 2013. EBF prevalence was higher among multiparous mothers (P < 0.001), mothers of Malay ethnicity (P < 0.05), and mothers of girls (P < 0.01 only in 2013) in both years. EBF prevalence among government-employed mothers (81.0%, 67.7%, and 57.8%) was greater than it was among nonworking mothers (79.1%, 66.3%, and 56.9%) by 1.9, 1.4, and 0.9 percentage points, respectively, during the first 3 months of active paid maternity leave in 2013. Mothers employed in the government and private sectors showed greater increases in the practice of EBF (15.5 and 10.8 percentage points respectively) than nonworking mothers (8.8 percentage points) from 2010 to 2013.

Conclusions
EBF prevalence increased after extending paid maternity leave, with the greatest increases seen among employed mothers. Maternal ethnicity, parity, and the sex of the infant were also correlated with EBF.
The future of marine biodiversity and marine ecosystem functioning in UK coastal and territorial waters (including UK Overseas Territories) – with an emphasis on marine macrophyte communities
Authors: Küpper Frithjof C. , Kamenos Nicholas A. 
Published: November 2018

Abstract
Marine biodiversity and ecosystem functioning – including seaweed communities – in the territorial waters of the UK and its Overseas Territories are facing unprecedented pressures. Key stressors are changes in ecosystem functioning due to biodiversity loss caused by ocean warming (species replacement and migration, e.g. affecting kelp forests), sea level rise (e.g. loss of habitats including salt marshes), plastic pollution (e.g. entanglement and ingestion), alien species with increasing numbers of alien seaweeds (e.g. outcompeting native species and parasite transmission), overexploitation (e.g. loss of energy supply further up the food web), habitat destruction (e.g. loss of nursery areas for commercially important species) and ocean acidification (e.g. skeletal weakening of ecosystem engineers including coralline algal beds). These stressors are currently affecting biodiversity, and their impact can be projected for the future. All stressors may act alone or in synergy. Marine biodiversity provides crucial goods and services. Climate change and biodiversity loss pose new challenges for legislation. In particular, there are implications of climate change for the designation and management of Marine Protected Areas and natural carbon storage by marine systems to help control the global climate system. The UK currently has legal obligations to protect biodiversity under international and European law.

Published: November 2018

Abstract
Let M be a compact complex manifold of dimension at least three and Π : M → X a positive principal elliptic fibration, where X is a compact Kähler orbifold. Fix a preferred Hermitian metric on M. In [14], the third author proved that every stable vector bundle on M is of the form L⊕ Π ⃰ B0, where B0 is a stable vector bundle on X, and L is a holomorphic line bundle on M. Here we prove that every stable Higgs bundle on M is of the form (L ⊕ Π ⃰B0, Π ⃰ ɸX), where (B0, ɸX) is a stable Higgs bundle on X and L is a holomorphic line bundle on M.

AbstractBackground: The aim of this study was to investigate the diagnostic performance of serum homocysteine (Hcy) and Essen stroke risk score (ESRS) in prediction of progressing acute ischemic stroke (PAIS).Methods One hundred and thirty two acute ischemic stroke (AIS) patients were retrospectively recruited from Daping Hospital, Third Military Medical University from February 2016 to January 2018. The 132 AIS patients were divided into PAIS and non-progressing AIS (NPAIS) groups according to the definition of PAIS. The clinical characteristics, serum Hcy concentration, and ESRS were compared between the PAIS and NPAIS groups. The independent risk factors for PAIS were evaluated by logistic regression analysis. The prediction sensitivity, specificity and area under the ROC curve (AUC) of serum Hcy and ESRS for PAIS were calculated using STATA11.0 software.Results: The elevated ESRS (OR=1.82, p<0.05), serum fibrinogen (FIB) (OR=1.18, p<0.05), Hcy (OR=1.21, p<0.05) and personal stroke history (OR=1.74, p<0.05) were independent risk factors for PAIS. The serum Hcy of the PAIS and NPAIS groups were 24.59±9.24 (μmol/L) and 18.20±8.29 (μmol/L) respectively with a statistical significance of p<0.05. The ESRS were 3.43±1.09 and 2.60±0.92 for the PAIS and NPAIS groups respectively, with a significance of p<0.05. The prediction sensitivity, specificity and AUC were 76.24%, 67.74% and 0.73 (95%CI:0.63-0.83), respectively, for serum Hcy. For ESRS, the prediction sensitivity, specificity and AUC were 69.99%, 64.52% and 0.74 (95%CI:0.63-0.84) respectively. Correlation between serum Hcy and ESRS was evaluated by a Pearson correlation test. Significant positive correlation between serum Hcy and ESRS was found in PAIS (r=0.54, p<0.05), and NPAIS patients (r=0.78, p<0.01).Conclusion: Patients with elevated ESRS, serum FIB, Hcy and stroke history had an elevated risk of developing PAIS.

This article gives a theoretical substantiation and a new experimental solution of a scientific problem aimed at increasing the effectiveness of pharmacotherapy on the morphofunctional state of the lungs of rats under conditions of burn shock by using a combined colloid-hyperosmolar infusion solution – lacto-protein with sorbitol. The administration of the test solution at a dose of 10 ml/kg for 7 days in rats with modelled burn shock reduced ultrastructural changes in the lungs triggered by burn shock. It has been proved that in the conditions of shock, colloid-hyperosmolar infusion lacto-protein with sorbitol solution facilitates the restoration of vascular endothelium and fluid retention in the microcirculatory channel and improves the morphofunctional state of the aerohematic barrier of the lungs, stimulates the activity of the alveolar macrophages and the secretory function of the type II alveolocytes producing surfactant. At day 7 of burn shock, when 0.9% of NaCl was injected, significant changes were observed in the respiratory unit: part of the alveoli had considerably enhanced clearance of blood capillaries, which had platelets, neutrophils and altered forms of erythrocytes. At day 7 of burn shock in the lungs of the rats given an infusion of colloid-hyperosmolar solution – lactoprotein with sorbitol, the ultrastructure of the components of the lung cells had improved in comparison with 3 days. Luminosity of the hemocapillary parts was moderate, mainly with erythrocytes. The walls of endothelial cells had elongated nuclei with invaginations of nuclear membranes and clear contours. Their cytoplasmic regions were not widespread, with moderate electron densities. In type II alveolocytes, during this experiment, a lower degree of damage to the nucleus and organelles in the cytoplasm was established, and there were signs of a renewal of the secretory function of these cells. In the cytoplasm, hypertrophied mitochondria with clear crystals, different sizes of secretory granules, which had a different density, indicating their formation, were observed. According to the magnitude of the cytoprotective effect on lung cells under conditions of burn shock, the lactoprotein with sorbitol solution was shown to be superior in comparison with the physical solution (0.9% NaCl). The study of functional, biochemical and molecular genetic parameters that characterize the state of the aerohematic barrier under the conditions of using lactoprotein with sorbitol solution in the case of burn injuries of the skin will allow researchers to comprehensively evaluate the mechanisms of the pulmonary protective effect of this preparation and to experimentally substantiate the expediency of its use in clinical practice for pharmaco-correction of burn shock.

The Role of Elasto-Plasticity in Cavity Shape and Sand Production in Oil and Gas Wells
Authors: Wang Haotian , Sharma Mukul M. 
Published: November 2018

Summary
Previous experimental observations have shown the formation of distinct failure patterns and cavity shapes under different stress and flow conditions. With isotropic stress, spiral failure patterns with localized shear bands are likely to form. On the other hand, under anisotropic stress, V-shaped cavities, dog-ear cavities, or slit-mode cavities are usually observed. However, the mechanisms for the development of these sanding cavities have not been fully articulated. In addition, to accurately predict the onset of sanding and to predict the sand-production rate, it is crucial to capture the physics of the formation of these cavities during sand production.
This paper presents a fully coupled poro-elasto-plastic, 3D sand-production model for sand-production prediction around openhole and perforated wellbores in a weakly consolidated formation. Sanding criteria are based on a combination of shear failure, tensile failure, and compressive failure from the Mohr-Coulomb theory and strain-hardening/softening. After the failure criteria are met, an algorithm for the entrainment of the sand based on the calculation of hydrodynamic forces is implemented to predict sand erosion and transport. Dynamic mesh refinement has been implemented to effectively capture the strain-localization regions.
The model has been validated with multiple analytical solutions. In addition, it is applied to compare with previous sand-production experiments that have explored the different cavity shapes formed under different conditions. The model is capable of not only explaining the mechanisms responsible for each type of cavity shape but also predicting the cavity shape that will be formed under a specific set of conditions. Parametric studies for these cases provide an additional insight into the important role that the post-yield, poro-elasto-plastic properties of the sand play in controlling the sanding mechanisms and cavity development. This allows us to predict, much more accurately, the onset of sanding and the sanding rate.
Pollution characteristics and fate of microfibers in the wastewater from textile dyeing wastewater treatment plant

Published: November 2018

Abstract
Wastewater discharged from wastewater treatment plants (WWTPs) is suspected to be a significant contributor of microplastics (MPs) to the environment, and fiber is the main shape of MPs in wastewater effluent. A typical textile industry WWTP with 30,000 tons of daily treatment capacity was sampled for microfibers at different stages of the treatment process to ascertain at what stage in the treatment process the microfibers are being removed. The average abundance of microfibers was 334.1 (±24.3) items/litre in influent, and it reduced to 16.3 (±1.2) items/litre in the final effluent with a decrease of 95.1%. Despite this large reduction we calculated that this textile industry WWTP was releasing 4.89 × 108 microfibers including microplastic fibers and non-microplastic fibers into the receiving water every day. This study showed that a modest amount of microplastics being released per litre of effluent could result in significant amounts of fibers entering the environment, despite the fact that efficient removal rates of microplastic fibers and non-microplastic fibers were achieved by this modern treatment plant when dealing with such a large volume of effluent. The fate of fibers is described during the textile industry wastewater treatment process.

Published: November 2018

Objective:
The label free ultrasmall fluorescent ferrite clusters have been engineered in a
controlled fashion which was stabilized by serum protein and functionalized by folic acid for the application
of targeted multimodal optical and Magnetic Resonance (MR) cancer imaging.

Methods:
The ultra-small manganese ferrite nanoclusters (PMNCs) with a diameter of 4 nm have a
commendable effect on the longitudinal (T1) and transverse (T2) relaxation in MR imaging that was
evident from the phantom and animal MRI.

Results:
The calculated longitudinal molar relaxivity of nanoclusters was found to be 6.9 ± 0.10 mM-1
S-1 which was exactly 2.22 times better than the conventional Gd-DOTA and their 4.01 ratio of the
transverse (r2) and longitudinal (r1) relaxivities made them a potential candidate for both T1 and T2
contrast agents in MRI. In addition, the fluorescence-based small animal imaging showed folic acid
driven accumulated fluorescent signal at the tumour site to conclude the capacity of PMNCs for targeted
fluorescence imaging of cancer diagnosis.

Conclusion: The cytotoxicity assay and histopathology studies were the evidence for their safe biodistribution
in animal systems. Furthermore, the protein encapsulated clusters have the ability to deliver
the anticancer drug Methotrexate (MTX) to the cancer tissues with a sustained manner. Therefore, one
can conclude the remarkable efficacy of architect nanoclusters for theragnosis.

Published: November 2018

Background:The 18 kDa translocator protein (TSPO), previously known as the peripheral- type benzodiazepine receptor, plays a key role for the synthesis of neurosteroids by promoting transport of cholesterol from the outer to the inner mitochondrial membrane, which is the ratelimiting step in neurosteroid biosynthesis. Neurosteroids interact with nonbenzodiazepine site of GABAa receptor causing an anxiolytic effect without the side effects.Methods:Using the original peptide drug-based design strategy, the first putative dipeptide ligand of the TSPO N-carbobenzoxy-L-tryptophanyl-L-isoleucine amide (GD-23) was obtained. Molecular docking of GD-23 in the active pocket of the TSPO receptor using Glide software was carried out. The lead compounds GD-23 and its analogues were synthesized using activated succinimide esters coupling method. The anxiolytic activity of GD-23 and its analogues was investigated in vivo, using two validated behavioral tests, illuminated open field and elevated plus-maze.Results:he in vivo studies revealed that the following parameters are necessary for the manifestation of anxiolytic activity of new compounds: the L-configuration of tryptophan, the presence of an amide group at the C-terminus, the specific size of the N-acyl substituent at the Nterminus. Compound GD-23 (N-carbobenzoxy-L-tryptophanyl-L-isoleucine amide) demonstrated a high anxiolytic-like effect in the doses of 0.05–1.0 mg/kg i.p. comparable with that of diazepam. Compound GD-23 was also active in the open field test when was administered orally in the doses of 0.1-5.0 mg/kg. The involvement of TSPO receptor in the mechanism of anxiolytic-like activity of new compounds was proved by the antagonism of compound GD-23 with TSPO selective inhibitor PK11195 as well as with inhibitors of enzymes which are involved in the biosynthesis of neurosteroids, trilostane and finasteride.Conclusion:A series of N-acyl-tryptophanyl-containing dipeptides were designed and synthesized as 18 kDa translocator protein (TSPO) ligands. Using a drug-based peptide design method a series of the first dipeptide TSPO ligands have been designed and synthesized and their anxiolytic activity has been evaluated. In general, some of the compounds displayed a high level of anxiolytic efficacy comparable with that of diazepam. The involvement of TSPO receptor in the mechanism of anxiolytic activity of new compounds was proved using two methods. On this basis, the N-acyl-Ltryptophanyl- isoleucine amides could potentially be a novel class of TSPO ligands with anxiolytic activity.

AbstractThe effect of the material of the metal plates (Au, Ta, W) and exposure to a high-power blue laser on the memristive characteristics of metal–insulator–semiconductor (MIS) capacitors with a Si_3N_4 film 6 nm thick fabricated on the basis of n ^+-Si is studied. It is shown that bipolar switching by the current appears only in capacitors with Au. The causes of the absence of bipolar switching in capacitors with Ta and W are explained. The switching of capacitors with Ta by the current and light and the photomemory effect are detected. It is shown that, despite the high doping level of the semiconductor substrate, it decreases the MIS memristor response rate due to a high density of surface states localized at the Si_3N_4/ n ^+-Si interface. However, illumination allows a significant increase in the response rate due to a decrease in the semiconductor resistivity. The surface state densities are determined. To improve the frequency characteristics of MIS memristors, it is necessary to achieve a low surface state density.

AbstractThe longitudinal ρ_ xx and Hall ρ_ xy resistances were measured in the region of the quantum phase transitions for the quantum Hall effect regime with magnetic fields up to 12 T at temperatures of T = 0.4–30 K in two-dimensional electron systems n -In_0.9Ga_0.1As/In_0.81Al_0.19As. The nonuniversal scaling behavior of the temperature dependence of the width of the resistance ρ_ xx peaks related to the effect of the large-scale random potential and of Landau-level mixing with opposite spin directions was found.
