Authors: Gomes Luís , Borges Carlos , Serralheiro M Luísa M , Minhalma Miguel , Pacheco Rita 
Published: September 2017

AbstractBACKGROUNDCork processing wastewater is an environmental problem due to its high content of organic matter, such as sugars and non‐biodegradable compounds such as polyphenols (PPs), namely tannins. Membrane technology aimed at valorisation of the wastewaters components, concentrate stream, and simultaneously offer a pre‐treatment of the wastewater, permeate stream. In this work, the identification of bioactive PPs was also envisaged. Several fractions of cork processing wastewaters were generated using two cellulose acetate ultrafiltration membranes of 3 kDa and 74 kDa for PPs isolation according to nature and molecular weights. The membranes were prepared by the phase inversion method and fractionation was made in concentration and diafiltration modes. The wastewater and the fractions were analyzed in terms of total organic carbon, total phenols, tannins and total polysaccharides content and the compounds present were identified by FTIR, LC–MS and quantified by HPLC‐DAD.RESULTSCompounds such as quinic, gallic, protocatechuic, brevifolin carboxylic and ellagic acids were identified as the major compounds in cork wastewater. The wastewater and the fractions were tested for antioxidant activity and for capacity to inhibit the proliferation of the growth of human breast carcinoma cell lines, MCF‐7. The fractions revealed high antioxidant activity with EC50 values ranging from 1.174 ± 0.069 to 1.943 ± 0.179 mg/mgDPPH. The fractions demonstrated to be efficient as cell proliferation inhibitors, with values of IC50 ranging from 0.20 ± 0.003 to 0.46 ± 0.02 mg mL‐1.CONCLUSIONThe process reported demonstrates that PPs compounds can be recovered from cork effluent and further reused as high‐value bioactive compounds. © 2017 Society of Chemical Industry

AbstractFive strains were isolated from gonad of Great scallop (Pecten maximus) broodstock in a Norwegian hatchery. The study of 16S rRNA gene sequences showed that these isolates belong to Neptunomonas phycophila, a bacterium originally isolated from a symbiont of the anemone Aiptasia tagetes from Puerto Rico. The gyrB and rpoB genes sequences confirmed the affiliation of the scallop isolates to this species. Phenotypic characterization was performed and some differences between the Norwegian isolates and the type strain of N. phycophila were detected, such as ranges of temperature, pH, and tolerance to salinity or the use of several substrates as sole carbon source which lead to an emended description of the species. The strain 3CM2.5 showed phosphatidylethanolamine and phosphatidylglycerol as the major polar lipids. The whole genomes of the scallop strain 3CM2.5 and type strain of the species CECT 8716T were obtained and the annotation of these genomes revealed the presence of genes involved in degradation of aromatic compounds in both strains. Results obtained not only widen the geographical and host ranges of N. phycophila, but also point out possible biotechnological applications for this bacterial species.

Published: September 2017

ObjectiveThe aim of this study was to determine the influence of a gas exchange correction protocol on resting metabolic rate (RMR) and respiratory quotient (RQ), assessed by a Vmax Encore 29n metabolic cart (SensorMedics Co., Yorba Linda, California) in overnight fasted and fed humans, and to assess the predictive power of body size for corrected and uncorrected RMR.MethodsHealthy participants (23 M/29 F; 34 ± 9 years old; 26.3 ± 3.7 kg/m2) ingested two 3‐hour‐apart glucose loads (75 g). Indirect calorimetry was conducted before and hourly over a 6‐hour period. Immediately after indirect calorimetry assessment, gas exchange was simulated through high‐precision mass‐flow regulators, which permitted the correction of RMR and RQ values.ResultsUncorrected and corrected RMR and RQ were directly related at each time over the 6‐hour period. However, uncorrected versus corrected RMR was 6.9% ± 0.5% higher (128 ± 7 kcal/d; P < 0.0001), while RQ was 14.0 ± 0.4% lower (−0.114 ± 0.003; P < 0.0001) when compared throughout the whole period. Body weight, sex, and age explained a larger fraction of the variance when corrected RMR was considered (adjusted R2 = 0.71; P < 0.0001) versus uncorrected RMR (adjusted R2 = 0.59; P < 0.0001).ConclusionsApplying a protocol to correct gas exchange in humans over a 6‐hour period is feasible and provides information of improved accuracy.

Published: September 2017

AbstractTwo kinds of reduced sensitivity high explosive 1,3,5,7‐tetranitro‐1,3,5,7‐tetrazocane (RS‐HMX) with different particle sizes were selected to enhance the energy output and the mechanical properties of insensitive high explosive 1,3,5‐triamino‐2,4,6‐trinitrobenzene (TATB). Mechanical sensitivities, dynamic mechanical analysis, and non‐linear time dependent creep behaviors of TATB/HMX composites were investigated and discussed in relation to the structural characteristics. Compared with TATB/conventional HMX (C‐HMX) sample, both the impact and friction sensitivities of TATB/RS‐HMX were reduced. It revealed that TATB/fine grains RS‐HMX composites had the highest storage modulus and minimum steady‐state creep strain rate due to the increased coherence strength and the inhibited slide of the single layer of TATB crystal. The creep resistance also showed clear dependence on the particle size of RS‐HMX. The overall results indicated that RS‐HMX had good potential in high energetic, safe, and load‐bearing material applications.

Published: September 2017

AbstractSelf‐powered ultraviolet (UV) photodetectors, which have vast applications in the military and for civilian purposes, have become particularly attractive in recent years due to their advantages of high sensitivity, ultrasmall size, and low power consumption. In particular, self‐powered UV photodetectors driven by a built‐in electric field cannot only detect UV signals but also be powered by the incident signals instead of external power. In this concept, the key issues and most recent developments on photovoltaic type UV photodetectors driven by p–n homojunction, heterojunction, and Schottky junction are surveyed. This should generate extensive interest in this field and encourage more researchers to engage in and tackle the scientific challenges.

AbstractBackgroundThere is no consensus about remnant liver regeneration associated with middle hepatic vein (MHV) resecting.MethodsSeventy‐five patients who underwent hemihepatectomy were retrospectively analysed with respect to remnant liver regeneration. The liver remnant volume (LRV) and each sectional volume were postoperatively measured with multidetector computed tomography at day 7 and months 1, 2, 5, and 12 after the operation.ResultsIn right hemihepatectomy cases, the regeneration rate of LRV in the MHV preservation group was significantly higher than that of the MHV resection group at months 5 and 12. In particular, the regeneration rate of remnant segment IV peaked at day 7 and was shrunk after 1 month, and was significant higher in the MHV preservation group. In left hemihepatectomy cases, the regeneration rate of LRV at month 12 was significantly higher in the MHV preservation group. The regeneration rate of the remnant anterior section peaked at 1 month and was shrunk.ConclusionIn this study, the MHV should be preserved or reconstructed whenever possible during hepatic hemihepatectomy. Hepatic regeneration in the MHV perfusion region becomes poor within 7 days to 1 month after surgery (UMIN000023714).

AbstractBackgroundTo evaluate the clinical significance of a CT‐based evaluation of abdominal aortic calcification (AAC) in the postoperative outcomes after pancreaticoduodenectomy (PD) in elderly patients.MethodsPatients 70 years of age and older who were randomly assigned to Group A were compared with those younger than 70 who were assigned to Group B in terms of preoperative and intraoperative variables and postoperative outcomes. We compared the patients with clinically relevant postoperative pancreatic fistula (CR‐POPF) (Group C) to those without CR‐POPF (Group D), and especially Group A. We also compared the patients with CR‐POPF (Group E) to those without CR‐POPF (Group E) to clarify the risk factors for POPF, in each of the analyses. The AAC score was determined using the methods of Agatston et al.ResultsGroup A more often had frequent atherosclerosis‐related comorbidities (62.2%), low serum albumin (55.9%), and a high AAC score (66.1%). There were no significant differences in the postoperative variables. The comparisons between Groups C and D identified four independent risk factors for CR‐POPF: BMI ≥ 25 (OR 8.54, 95% CI 3.15–23.1), male gender (OR 3.17, 95% CI 1.28–7.85), soft pancreatic parenchyma (OR 3.43, 95% CI 1.34–8.81), and the absence of MPD dilatation (OR 5.70, 95% CI 2.13–15.3). Comparisons between Groups E and F identified two independent risk factors for CR‐POPF: BMI ≥ 25 (OR 29.4, 95% CI 5.77–150) and a high ACC score (OR 10.8, 95% CI 2.08–56.6).ConclusionsWe demonstrated, for the first time, that a high AAC score is a risk factor of CR‐POPF in elderly patients who underwent PD.

Published: September 2017

ABSTRACT
Jaisalmer Formation consists of 360m thick succession of medium to coarse grained sandstones with interbeds of shale, claystone and occasional lignite that rest over Lathi Formation, is the basal part of the Jaisalmer basin. The rocks are exposed amidst desert, low mounds and shallow stone quarries. Sandstones were deposited in shallow marine to deltaic environments. The studied sandstones consist of abundant quartz followed by feldspar, mica, chert, rock fragments and heavy minerals. The study mainly deals with identification of various diagenetic features such as compaction, cementation and porosity evolution. During mechanical compaction rearrangement of grains took place and point, long and suture contacts were formed. The sandstones are cemented by iron oxide, silica overgrowth, carbonate and clay. Porosity has developed due to dissolution of iron, carbonate cement and feldspar grains. Dissolution and alteration of feldspar, lithic fragments and pressure solution were the main source of quartz cements. The sandstones show good amount of existing optical porosity with an average of 7.19%. Porosity reduction is mainly due to early stage of mechanical compaction and subsequent pervasive calcite and iron oxide cementation. Further, porosity reduced due to deposition of clay cement.

Published: September 2017

ABSTRACT
A study on the sedimentary facies characterization and depositional environment interpretations for the K#Field (K-Oil Field) in Cambay petroleum basin of western onshore, India was conducted based on the sub-surface data from drilled wells, including well logs, borehole images, cores and the regional knowledge of the basin. In this work, an effort is made to integrate the current data from seismics and well logging, to study and analyze its depositional environments and establish the petroleum systems. The study regions for the present work are K45 and K48 blocks. The target strata includes 2 oil-bearing formations of Paleogene, which is about 3600 ft; they are M#Fm (M-Formation) of the Eocene and N#Fm (N-Formation) of Oligocene, subdivided into 11 zones. The sediment fill is mostly of Tertiary. The research attempts to decipher the oil - depositional source correlation problems of the basin. Sedimentary models were established referring to the core analysis, core photographs and well logs. Reservoir and heterogeneity study included reservoir lithology features, physical properties and pore structure features. Well facies analysis of oil well WELL-0297 and WELL-0129 was done and the results were analyzed for further drilling of new wells for oil and gas exploration. The study found that the Eocene, Oligocene, Miocene and Paleogene are fluviatile facies sand and mud inter-bed sediment with the thickness 2000-4000 ft, which are main oil-bearing formations in these areas. Studies concluded that the fluvial reservoirs of the K#Field are characterized by large variations from laterally extensive bodies with good interconnectedness and high net-to-gross ratios, multi-storey ribbon bodies with poor interconnections and low net-to-gross ratios.
Structural Interpretation and Hydrocarbon Potential of Balkassar Oil Field, Eastern Potwar, Pakistan, using Seismic 2D Data and Petrophysical Analysis

Published: September 2017

Abstract
The Balkassar oil field is situated in the eastern Potwar sub-basin, lies on the southern flank of Soan syncline in Himalayan collisional regime. The area represents Indo-Pak and Eurasian blocks of Precambrian to recent time. Thrusting and folding of Himalayan, Indo-Pak plate movement and Salt Range uplift form the structural trap in Balkassar sub-surface (Balkassar anticline). On the basis of information from eleven seismic 2D lines and wells data six reflectors well data, four faults were identified and marked. The structural trend is northeast southwest. Interpretation of seismic 2D data reveals that the study area has undergone intense deformation as a consequence of development of thrusts and backthrusts. The Balkassar anticline is bounded by two thrust faults one from southeast and the other from northwest. Time and depth contour models shows that anticline limbs at north-western side are steep as compared to south-eastern limbs. Seismic interpretation indicates the presence of well-developed anticline bounded by three faults in the cover sequence and one fault in basement and thus the structure may act as a trap for hydrocarbons. The petrophysical analysis of Balkassar-OXY-1 well shows about 83.1% hydrocarbons saturation in the reservoir rocks, hence this study suggest that Balkassar Oilfield has potential to produce hydrocarbons.
Assessment of Water Quality Index for the Groundwater in the Upper Cheliff Plain, Algeria
Authors: Bouderbala Abdelkader 
Published: September 2017

ABSTRACT
Assessment of groundwater suitability for drinking and agricultural purposes was carried out in the plain of upper Cheliff. The study area covers an area of 375 km2 and lies in a semiarid climate. Groundwater is the major source for domestic and agricultural activity in this area. Groundwater samples were collected from 19 wells during dry and wet periods in 2012, and they were analyzed for major cations and anions and compared with drinking and irrigation specification standards. The concentration of the majority of chemical constituents exceeds the standards of WHO as a result of various sources of pollution. It indicates the dominance of groundwater types: Ca-Mg-Cl, and Ca-Mg-HCO3. Suitability of groundwater for drinking was evaluated based on the water quality index; it shows more than 60% of samples have very poor quality for dry and wet periods, which means water is severely contaminated and unsuitable for drinking purpose. In terms of the irrigation usage, generally groundwater is suitable for both periods in the major part of the plain. The Mineralization processes in this area is determined by the lithology of the aquifer (exchange water-rock), by anthropogenic factors (discharges of urban sewage, use of fertilizers) and also by evaporation (semi-arid climate).

AbstractBackgroundSeveral studies have investigated the association of angiotensin‐converting enzyme (ACE) gene insertion/deletion (I/D) polymorphism with peripheral vascular disease (PVD); however, the results remain controversial. Therefore, we conducted the current meta‐analysis to evaluate this relationship in the general population of different ethnicities.MethodsWe searched PubMed, Embase, Web of Science, Wanfang Database, and CNKI to identify eligible studies. Random‐effect models were applied to estimate the pooled odds ratio (OR) with a 95% confidence interval (CI), regardless of between‐study heterogeneity.ResultsA total of 13 studies with 1966 cases and 6129 controls were included in this meta‐analysis. The pooled ORs for the association between ACE I/D polymorphism and PVD risk were not statistically significant in the overall population under all genetic models. In further ethnicity‐stratified analyses, we found a statistically significant association of ACE I/D polymorphism with PVD susceptibility in Asians under most models. However, the association among Caucasians did not reach statistical significance.ConclusionACE I/D polymorphism might be associated with susceptibility to PVD in the Asian population, but there was no clear evidence indicating a similar significant relationship among Caucasians.

Abstract
New characteristics and generalized geostructural, isotope-geochronological, and paleomagnetic data are presented for the first time for the territory of Jeannette Island in the De Long Archipelago. Until recently, this small rock outcrop in the East Siberian Sea, discovered in the late 19th century, has been in effect a blank spot on the geological map. Field work made in 2013 and subsequent laboratory analysis of the obtained sample collection show that the island has a volcanogenic-sedimentary section including many thin (up to several meters) dolerite dikes. These dikes are the main target of the study. Newly obtained 40Ar/39Ar isotope-geochronological data indicate that the earliest dike intrusion stage corresponds to the Ediacaran (553.6 ± 10.3 Ma). Several subsequent tectonothermal events can be inferred until and through the Early Carboniferous, which affected the stability of the isotope system in the dolerites. In addition, paleomagnetic data confirm at least one more stage of dike emplacement, in the Early Ordovician, as the coordinates of the virtual geomagnetic poles for the dikes are nearly identical to those of the Ordovician paleomagnetic pole determined for carbonate rocks of Kotelny Island. The study describes the main petromagnetic characteristics and magnetic mineralogy of the studied dolerites, validating the primary thermoremanent nature of the identified characteristic component. The results agree with available information on the paleomagnetism, tectonics, and paleogeography of the New Siberian Islands.

AbstractObjectiveA series of sniper attacks in the Washington, DC, area left 10 people dead and 3 wounded. We developed and tested a model that examined the unique and interdependent relationships of sniper-related television viewing, prior life-threatening events, and parental status to identification with attack victims.MethodsParticipants were 1238 residents of the DC area (aged 18-90 years, mean=41.7 years; 51% female; 68% white) who completed an online survey that assessed identification with sniper attack victims, amount of television viewing, and prior life-threatening events. Identification was measured by using a previously developed scale that assessed to what extent participants identified victims as similar to themselves, a friend, or a family member.ResultsThe relationship of television viewing to identification was examined by using multivariate linear regression analyses. In univariate analyses, female gender, having children, higher levels of television viewing, and past life-threatening events were independently related to greater identification. After adjustment for demographics and life-threatening events, sniper-related television viewing continued to be associated with identification (B=0.61,P≤0.001, ∆R2=0.07). Examination of the interactions of television viewing by parental status and television viewing by life-threatening event revealed significant relationships.ConclusionsAttention to events preceding and during a terrorist event could help in the recognition of those at particular risk for increased identification with attack victims. These findings also have implications for recommendations for media exposure during an event. (Disaster Med Public Health Preparedness. 2018; 12: 337–344)
