Ranking of Indicators for Estimation of Plant Efficiency in Hydropower Plants by a Bootstrap MCDM Approach
Authors: Majumder Priyanka , Saha Apu Kumar
Published: April 2019

The overall commitment of hydropower plants (HPP) in providing the interest for power is 1106 TWh. The issue with hydropower lies with the way that its proficiency relies upon numerous indicators which are elements of climatic, pressure driven and financial markets. Every one of these indicators again rely on pressure driven misfortune forced because of the time being used, change in energy requirements, locational interference and quality of the machine installed. As there are numerous indicators having diverse levels of impact on the execution productivity of HPP, a few indicators are exaggerated and some others stay under appraised which brings about incorrect basic leadership. The present study proposes another cross breed show in view of the Decision-Making Trial and Evaluation Laboratory (DEMATEL) with the Analytic Hierarchy Process (AHP). Also in the present investigation rank of each indicator determine by Statistical Process Control (SPC). The needs are dictated by hybrid technique in particular SPC-DEMATEL-AHP. As per the outcomes, effectiveness of turbine is the most noteworthy for impacting general productivity of HPP.

Authors: Sweileh Omar , Hassan Mohamed S. , Mir Hasan S. , Ismail Mahmoud H.
Published: April 2019

In this article, an opportunistic inter-frame spectrum scheduler that maximizes the throughput of cognitive radio networks over a span of multiple time-slots is proposed. An optimization problem is formulated to find the optimum inter-frame scheduler while taking into account the switching delay, the primary user (PU) activity, historical information on the PU behavior, the channel quality as well as the secondary user (SU) status. Simulation results show that the proposed inter-frame scheduler significantly improved the overall aggregate throughput and average switching delay of the cognitive radio network when compared to the values obtained when scheduling is done on a slot-by-slot basis.

Authors: Boukhari Noureddine , Debbat Fatima , Monmarché Nicolas , Slimane Mohamed
Published: April 2019

The main purpose of this article is to demonstrate how evolution strategy optimizers can be improved by incorporating an efficient hybridization scheme with restart strategy in order to jump out of local solution regions. The authors propose a hybrid (μ, λ)ES-NM algorithm based on the Nelder-Mead (NM) simplex search method and evolution strategy algorithm (ES) for unconstrained optimization. At first, a modified NM, called Adaptive Nelder-Mead (ANM) is used that exhibits better properties than standard NM and self-adaptive evolution strategy algorithm is applied for better performance, in addition to a new contraction criterion is proposed in this work. (μ, λ)ES-NM is balancing between the global exploration of the evolution strategy algorithm and the deep exploitation of the Nelder-Mead method. The experiment results show the efficiency of the new algorithm and its ability to solve optimization problems in the performance of accuracy, robustness, and adaptability.

Authors: Pham Duc Huu
Published: April 2019

To help EFL learners realize the use of nominals and clauses in practicing productive skills of academic writing in English writing tests, experiments have been exploited using the tasks similar to those of internet-based test of English as a foreign language to determine the nominal and clause level information during sentence and paragraph processing. Subjects were placed in two groups (the treatment group and the control group) and comprised English intermediate level students at a university in Vietnam performing compositions that were of lexical and clausal congruence but the congruence with discourse context was manipulated. The results indicated that lexical and clausal processing and discourse congruence have an effect on each other and influence writing skills. The study was undertaken as a basis for improving the technology-linguistics combined intake of learners' knowledge in order to accelerate the acquisition of foreign languages and will benefit future research related to computerized writing and assessment of writing.

Abstract. Indonesia contains large areas of peatland which are being drained and cleared of natural vegetation, making them susceptible to burning. Peat fires emit considerable amounts of carbon dioxide, particulate matter (PM) and other trace gases, contributing to climate change and causing regional air pollution. However emissions from peat fires are uncertain due to uncertainties in emission factors and burn depth of peat. We used the Weather Research and Forecasting model with chemistry, and measurements of PM concentrations to constrain PM emissions from Indonesian fires during 2015, one of the largest fire seasons in recent decades. We estimate PM2.5 (particles with diameters less than 2.5 μm) emissions from fires across Sumatra and Borneo during September to October 2015 were 7.33 Tg, a factor 3.5 greater than those in Fire Inventory from NCAR (FINNv1.5), which does not include peat burning. We estimate similar dry fuel consumption and CO2 emissions to those in the Global Fire Emissions Database (GFED4s), but a factor 1.8 greater PM2.5 emissions, due to updated PM2.5 emission factors for Indonesian peat. Through comparing simulated and measured PM concentrations, our work provides an independent confirmation of these updated emission factors. We estimate peat burning contributes 71 % of total PM2.5 emissions from fire in Indonesia during September–October 2015. We show that using satellite-retrieved soil moisture to modify the assumed depth of peat burn improves the simulation of PM, increasing the correlation between simulated and observed PM from 0.48 to 0.56. Overall, our work suggests that peat fires in Indonesia produce substantially greater PM emissions than estimated in current emission datasets, with implications for the predicted air quality impacts of peat burning.
Identifying possible Stratification phenomenon in ionospheric F2 Layer using the data observed by the Demeter satellite: Method and Results
Authors: Wang Xiuying , Yang Dehe , Liu Dapeng , Chu Wei
Published: April 2019

Abstract. Many studies have revealed the stratification phenomenon of the topside ionospheric F2 layer using ground-based or satellite-based ionograms, which can show direct signs of this phenomenon. However, it is difficult to identify this phenomenon using the satellite-based in situ electron density data. Therefore, a statistical method, using the shuffle resampling skill, is adopted in this paper. For the first time, in situ electron density data, recorded by the same Langmuir probe onboard the Demeter satellite at different altitudes, are analyzed and a possible stratification phenomenon is identified using the proposed method. Our results show that the nighttime stratification, possibly a permanent phenomenon, can cover most longitudes near the geomagnetic equator, which is not found from the daytime data. The arch-like nighttime stratification decreases slowly on the summer hemisphere and thus extends a larger latitudinal distance from the geomagnetic equator. All results, obtained by the proposed method, indicate that the stratification phenomenon is more complex than what has previously been found. The proposed method thus is an effective one, which can also be used on similar studies of comparing fluctuated data.
The quality of rainwater collected from roofs in the aspect of the
possibility of their economic use
Authors: Zdeb Monika M. , Zamorska Justyna , Papciak Dorota , Słyś Daniel
Published: April 2019

Abstract. The large variability in rainwater quality both in time and location as well as the relatively small number of tests make the preliminary assessment of economic exploitation of these waters difficult. Determining the relation between the conditions and location of rainwater collection and rainwater quality would help to indicate the range of options for rainwater use as well as parameters that require improvement. The aim of the presented article is to establish chosen physical, chemical and microbiological parameters of rainwater and, based on the results obtained, to determine the possibilities for a safe use of these waters in households. The research had been carried out for two years. Samples of chosen rainfalls were collected from spring to autumn from the following roofing materials: concrete roof tiles, ceramic roof tiles, zinc coated metal sheets and epoxy coated. The physical, chemical and microbiological quality assessment has been conducted basing on the following parameters: reaction, turbidity, electrical conductivity, concentration of biogenic compounds, concentration of chosen elements, number of Escherichia coli as well as number faecal streptococci. A significant bacterial contamination, a decreased pH and an increased turbidity of rainwaters were identified, depending on the parameters of the roofing washed by rainfalls and the intensity and frequency of precipitation.

Published: April 2019

Abstract. Snow cover is an effective best indicator of climate change due to its effect on regional and global surface energy, water balance, hydrology, climate, and ecosystem function. We developed a long term Northern Hemisphere daily snow depth and snow water equivalent product (NHSnow) by the application of the support vector regression (SVR) snow depth retrieval algorithm to historical passive microwave sensors from 1992 to 2016. The accuracies of the snow depth product were evaluated against observed snow depth at meteorological stations along with the other two snow cover products (GlobSnow and ERA-Interim/Land) across the Northern Hemisphere. The evaluation results showed that NHSnow performs generally well with relatively high accuracy. Further analysis were performed across the Northern Hemisphere during 1992–2016, which used snow depth, total snow water equivalent (snow mass) and, snow cover days as indexes. Analysis showed the total snow water equivalent has a significant declining trends (~ 5794 km3 yr−1, 12.5 % reduction). Although spatial variation pattern of snow depth and snow cover days exhibited slight regional differences, it generally reveals a decreasing trend over most of the Northern Hemisphere. Our work provides evidence that rapid changes in snow depth and total snow water equivalent are occurring beginning at the turn of the 21st century with dramatic, surface-based warming.
Art as a Weapon: The Inverted Gaze in Julius Lips The Savage Hits Back
Authors: Brus Anna Katharina
Published: April 2019

This article investigates the history of the book, The Savage Hits Back or the White Man Through Native Eyes (Yale University Press, 1937), which opened up a kaleidoscopic view of global representations of Europeans, thus inverting the colonial gaze on the “Other.” The author, the German anthropologist and museum director Julius Lips, published his book in the heyday of race theory in Germany. Driven into exile by the Nazis, he read Indigenous representations of Westerners as a tool of empowerment against the hegemony of colonial power and merged a critique of colonialism and fascism. By analyzing the scholarly reception of The Savage Hits Back, the author revisits Lips's crucial assumptions. Honing in on Lips's ambiguous and strategic use of Indigenous North American objects against the background of his exile in the United States, this article illuminates the mutual imbrication of Lips's biography and his scholarly work in politically volatile times.

ung: Look at One Another
Authors: Bunn-Marcuse Kathryn , Collison Jisgang Nika
Published: April 2019

On the Northwest Coast of North America, artwork has always documented identity; relationships with each other, the earth, and the supernatural; and histories held by individuals, clans, or Nations—spanning back to time immemorial. Artists use local and introduced materials and embrace new mediums to represent how to make some sense out of the world. These artworks reflect complicated relationships that artists navigated with European and British explorers, settlers, colonial administrators, and visitors during a period when communities were grappling with fundamental changes in social practices and cultural expressions. Published histories of art from these regions represent historically selective collecting practices and inform what appears to be—but what was not—the full range of artistic production. Scholarship and exhibitions must represent the full range of aesthetic creations unstifled by biased conceptions of what constitutes Northwest Coast “art” in order to fully explore the cosmopolitan expressions of First Nations' imagery.

The objective of this work was to evaluate the effect of the application of cassava wastewater in the production of dry mass of the spontaneous vegetation and in the physical and chemical attributes of a Dystrocohesive Yellow Oxisol submitted to intensive mechanical preparation in the Bahia Recôncavo. The experimental design was a 2 × 2 factorial scheme in 4 randomized blocks, the bands consisting of the intensity of the mechanical preparation of plowing followed by sorting: T0: without preparation; T1: 4 preparations; T2: 8 preparations and T3: 12 preparations; the first factor is the presence of cassava wastewater: M-with cassava wastewater; W-only water and the second factor presence or not of vegetation: CV-with vegetation and SV-without vegetation. The results of the analysis of soil attributes in the depth of 0.0-0.15 m showed that the pH, saturation by base (V%), macroporosity (Ma) and total porosity (TP) decreased linearly with the increase of the intensity of the mechanical preparation, however soil density (SD) increased. The application of cassava wastewater reduced the resistance to penetration (PR), pH and Ca2+ and V% of the soil and increased the dry mass productivity of the spontaneous vegetation and the contents of phosphor.

Published: April 2019

Based on temperature charts, infrared skin thermography is widely used in human medicine, but little known in veterinary medicine. The application of the technique allows orthopedic clinical follow-up as well as aids in the diagnosis of breast tumors in humans, due to its ability to correlate vasculature alterations and tissue vitality with modification of the temperature pattern. For this reason it is applied in veterinary medicine for the detection of joint injuries in horses and animal production, little covering the medicine of small animals. Against of these phages the present study aims to elucidate and suggest its use for the diagnosis and postoperative follow-up of reconstructive surgeries in animals, as well as to evaluate therapeutic measures that seek to improve cutaneous healing, such as low power laser therapy.

Published: April 2019

Agricultural activity, if not well managed, is an important source of water pollution mainly by surface runoff. The aim of this study was to evaluate losses of water, soil and soluble nutrient (phosphorus, nitrogen and carbon) via runoff in large plots (hillslope from 3,000 to 11,000 m2) at slope of 4 to 5% in annual crops (corn and sunflower) and pasture systems under no-tillage and no-pesticides. The study was carried out at the Canguiri Experimental Farm of the Federal University of Paraná, Southern Brazil, in soil classified as Ferralsol in three systems (crop, pasture and crop-pasture). Soil physical and chemical attributes as well as topographic indices and soil cover were investigated to evaluate the possible impacts of these variables on losses. The runoff was measured after each rainfall event from November 2014 to October 2015. Runoff samples were taken to analyse sediment and nutrients. All systems had low water, soil and nutrients losses compared to no conservative agricultural systems. Higher losses occurred in the annual crops system and were influenced by soil cover, with an annual runoff coefficient of 0.62% (7 mm of water loss) and an annual soil loss of 2.6 kg ha-1. The seasonality (winter/summer) did not influence soil, water and nutrient losses.

Published: April 2019

Unlike feed barley, malting barley must meet a specific set of quality standards for acceptability by maltsters. Multiple quality criteria in addition to the grain yield makes ranking of genotypes challenging. The objective of this study was to apply data envelopment analysis (DEA) models to rank the efficiencies of 27 winter barley entries based on grain yield and quality indices. Four methods of DEA including Charnes, Cooper and Rhodes (CCR), Färe and Grosskopf (FG), Banker, Charnes and Cooper (BCC), and Seiford and Thrall (ST) used for the ranking. Testing trial included 14 two-rows and 13 six-rows winter barley. All entries except two, demonstrated high winter survival ratings. Overall, the six-row cultivars out-yielded the two-row cultivars by 18%. However, in terms of brewing quality, the two-row entries performed better than six-row entries and had 40% lower thinness, 12% higher plump, and lower grain protein content. The six-row entries had 32% higher germinative energy than two-row entries. The ranking by four models were not similar, however, SU-Mateo and Calypso had the highest efficiency (1.0) by all four models followed by Wintmalt and Vincenta.

Since abiotic and biotic factors can compromise the survival of bacteria and their viability, encapsulation of cells in biodegradable gel matrices, a biological macromolecule, is one alternative to have their shelf life extended. Here, it was developed a gel-based formulation of the bioinoculant Azospirillum brasilense strain AbV5 and determined the effect of trehalose and humic acid supplementation in viability and survival of bacteria. For each 2 ml of sodium alginate solution (3%), 1 ml of the inoculum was extruded in a solution containing sodium alginate complexed with calcium chloride, forming calcium alginate beads. Supplements were used in a ratio of 2:2:1. Treatments were peat; alginate; alginate + humic acid; alginate + trehalose 0.1 M; alginate + trehalose 1 M. Morphometric aspects, survival rate and viability were determined in 9 storage periods (3, 5, 7, 14, 21, 30, 45, 60, 90 days). As results, beads were able to sustain the growth of A. brasilense for 90 days. Shelf life quality decreased in all treatments and peat remained the best carrier. Encapsulation, despite promoting the greatest losses in the survival of bacteria in the first days, ensured better cell viability. Trehalose in low concentrations (0.1M) improved cell viability during storage, optimizing plant inoculation.

Published: April 2019

The aim of this study was to evaluate the interaction of biochar and phosphorus in substrate for seedling production of Brazil nut. A greenhouse experiment was carried out with the following treatments: five doses of biochar (0, 20, 40, 60 and 80 t ha-1) and effect of two levels of phosphorus (0 and 100 kg ha-1 of P2O5) with 4 replicates. The plant height, stem diameter and number of leaves were monthly evaluated. At the end of experiment (180 days), the plants were removed from the pots and were evaluated the dry weight of the seedlings (total, shoot and roots), absolute growth rate, height/diameter and shoot/root ratio, number of leaves, leaf gain and quality index of seedlings. There was a significant interaction between the biochar and phosphorus interaction. The elevation of the bioburden doses did not influence any variables with phosphorus. In the absence of phosphorus, the doses of up to 40 t ha-1 of biochar promoted the highest values of the analyzed variables. Higher doses of biochar (> 40 t ha-1) reduced the growth and seedlings quality, however, it was found that under phosphate fertilization, the seedlings were obtained better growth results.

Pineapple is a nutritionally demanding crop, with emphasis on potassium and nitrogen nutrients. In this context, the aim of this paper was to study the effect of nitrogen (N) and potassium (K) fertigation frequencies on the physical-chemical fruit characteristics of ‘Pérola’ pineapple crop. The experiment was conducted in a randomized block design, with 18 treatments and 4 replications. It was used a factorial scheme (4 × 4) + 1 + 1, which represents: four N fertigation frequencies applied by surface drip irrigation (4, 7, 27 and 54 times throughout the crop cycle); four K fertigation frequencies (4, 9, 35 and 70 times); one additional treatment (irrigated, but without fertigation); and one control (non irrigated and non fertigated). The fruit characteristics analyzed were: fruit mass with crown, yield, soluble solids, pH, titratable acidity and SS/TA ratio. The N fertigation frequencies had no effect on variables evaluated, however, the K frequencies had a significant influence on fruit mass with crown, yield and pH. The results showed that the effect of K frequencies applied through fertigation on pineapple yield and fruit physical-chemical quality was more pronounced in comparison to the effect of N applications. Monthly potassium fertigations, followed by four applications throughout the crop cycle, provided the greatest increase in fruit quality, allowing higher values of fruit mass, yield and pH.

The serpentinite is an alternative for the correction of soil acidity and is composed of calcium and magnesium silicate. The objective of this study was to evaluate the residual effect of the serpentinite application on soil chemical attributes and the effects on wheat crop productivity in a no-tillage system. The experimental design was a randomized block design, in a subdivided plot scheme, with four replications. The plots were constituted by serpentinite doses (0, 2, 4, 8 and 16 Mg ha-1) and in the subplots the soil collection layers (0.0-0.10 and 0.10-0.20 m). The chemical attributes of the soil evaluated at 41 months after the application of serpentinite, presented favorable results of the residual power of this corrective. The main results observed are related to the increase of pH, decrease of aluminum content and potential acidity, and increase of Ca, Mg and Si contents, cation exchange capacity (CTC) and base saturation. The residual of the serpentinite in the soil contributed with an improvement in the chemical attributes of the soil, which favored the increase of the dry mass, number of spikes and yield of the wheat crop.

In order to evaluate the growth, dry mass production, contents and accumulation of macro-and micronutrients in seedlings of assai palm (variety Pai d’égua) in clayey Oxisol we conducted a greenhouse experiment based on the missing element technique. The experimental design was completely randomized with 15 treatments in five replicates. The treatments were: complete fertilizer with liming (complete); no fertilizer and no liming (control); complete fertilization with lime but with the individual omission of nitrogen, phosphorus, potassium, calcium, calcium without lime, magnesium, magnesium without lime, sulfur, boron, copper, manganese and zinc. The following variables were analyzed: plant height, stipe diameter, leaf dry mass, stipe dry mass, and content and accumulation of nutrients in the leaves. The singly omission of N, P and Mg has limited the height of the assai palm. The following singly omissions in decreasing order: N > K > Mg affected the production of leaf dry mass, while the leaf area was restricted by the individual omissions, in order: N > P > K. Plant development as measured by relative growth of the aerial part is affected by the lack of P > K > N > Mg with an average reduction of 61.9%. The nutrients most required by assai palm follow the order: N > K > Ca > Mg > P > Mn > Zn > B > Cu > S.

Introduced species that become invasive alter the structural and functional organisation of the ecosystems of the host territories because of the absence of certain ecological locks. On a global scale, the consequences are very damaging for many key development-related sectors. Martinique, like all the islands of the Caribbean, is not immune to this phenomenon of biological invasion currently linked to greater globalisation. Among the potentially invasive introduced species and in the light of field observations, Funtumia elastica, native to tropical Africa, appears to have functional traits that could make it a species that is dangerous for local floristic diversity. Since no study exists in Martinique on the ecology of this taxon, we have set up a research protocol based on floristic surveys in various stations marked out by transects subdivided into quadrats. Using the data obtained, it has been possible to highlight the main features of the ecology of this species in terms of biodemography, ecological dominance, mesological affinities and of belonging to the different stages of vegetal succession.

Authors: Rosdahl Jullia A. , Kingsolver Karen
Published: April 2019

PurposeBurnout affects half of doctors in the United States. Programs to decrease burnout and foster resilience are needed to prevent loss of doctors in the workforce and maintain quality care. To ameliorate burnout at our eye center, we developed a resilience program and used a survey to identify additional groups with higher burnout for future interventions.MethodsThe eye center–wide resilience program consisted of the baseline burnout survey, short email wellness tips, a grand rounds presentation, short wellness presentations at faculty meetings, and a small group discussion series with clinical faculty. The anonymous burnout survey was performed prospectively online at the beginning of this program. The survey participants consisted of respondents at the Duke Eye Center, including all doctors, scientists, clinical and research staff, trainees, and administrative and educational staff, in June and July of 2017. The short, anonymous electronic survey consisted of 10 demographic questions, 2 validated burnout questions, and 1 validated work-life balance question.ResultsA total of 593 individuals were invited to participate, of whom 252 completed the survey. Overall, 37% of the respondents reported being emotionally exhausted, and 17% had experienced depersonalization. With regard to work-life balance, 43% of the respondents were satisfied and 34% were dissatisfied. Burnout was higher in respondents who participated in clinical care (P = 0.001), particularly among ophthalmic technicians (P = 0.044). Feedback from the doctors participating in the “Doctors Lounge” suggested perceived benefits, including enhanced collegiality, life skills, and improved self-management.ConclusionsOur baseline burnout survey showed higher burnout in our clinical workers, particularly in our ophthalmic technicians. Planning for next year will include the providers identified in the survey.
Wert(er)schöpfung: Die Krise des Pflegeberufs
Authors: Huber Anja
Published: April 2019

Nurses choose their profession because they want to help people. However, economic pressure prevents them from giving care according to their professional ethos. Consequently, this has led to a high staff turnover, which has aggravated the crisis in the nursing profession. This was shown by a survey of approximately 300 professional nurses, which highlighted that nurses who are able to work in accordance with their professional ethos are more content with their work and less likely to resign. In this study, Anja Huber sketches the path to this dilemma in four steps: she gives a historical overview of the nursing profession, analyses nurses’ changed working environment due to economic pressure, examines the changes in care professions using Luhmann’s theory and describes their consequences for the nursing profession today. In a fifth step, she develops possible solutions to the crisis. Anja Huber has a PhD and works as an organisational psychologist at the University of Applied Sciences in Zurich.
Revision and morphological analysis of the Ragadidae (Insecta, Diptera)
Authors: Wahlberg Emma
Published: April 2019

Several taxonomic groups within Empidoidea Latreille, 1809 have been subject to unclear phylogenetic assignments along with multiple parallel hypotheses causing difficulties in classification and morphological identification. This study reviews the internal classification of the Ragadidae and includes a diagnosis and description of all included subfamilies and genera based on the results of an analysis of morphological characters using maximum parsimony. Illustration of important characters and a key to all genera in the family is given. The genus Hormopeza Zetterstedt, 1838 is found to be most closely related to Anthepiscopus Becker, 1891 and Iteaphila Zetterstedt, 1838, and the subfamily Iteaphilinae Wahlberg & Johanson, 2018 is therefore expanded to also include that genus. Hormopeza is consequently excluded from Ragadinae Sinclair, 2016. This study provides diagnoses, descriptions and keys in a contribution to a thorough classification of the empidoid groups and increased ease in morphological recognition.

Publishing engineering research papers not only can facilitate funding but can also boost academic promotion. When researchers apply for an academic position or a new job, they must demonstrate their productivity based on the number and quality of their published articles. However, writing engineering research papers is a difficult and daunting task, especially for beginners. Many books and articles explain and provide guidelines on how scientific papers should be written, organized, and structured, including those that explain techniques to avoid imperfections and those that provide instructions for submission and publishing. However, they rarely provide unwritten rules for achieving success in the field of engineering. The aim of this paper is to focus on simple suggestions, useful tips, and unwritten rules for writing engineering research papers. This article provides a brief guide for new writers.

Published: April 2019

The determination of ammonium by potentiometry in flow injection coupled to a gaseous membrane microdevice is investigated. A nonactin tubular electrode as an ionophore was used for the detection of ammonium. For this sensor to be selective, a microdevice was built incorporating a gaseous diffusion membrane with the purpose of eliminating interferences. The response of the proposed methodology had a Nernstian response with an angular coefficient of 51.2 mV (R2 = 0.9836) in a range of 0.2 to 5.0 mg L-1. The limits of detection and quantification were calculated in 0.004 (S / N = 3) and 0.010 (S / N = 10) mg L-1. The repeatability of the measurements was determined in 1.3% (n = 10) with a sampling frequency of 13 samples h-1. Under optimum conditions a flow rate of the transporter of 0.5 ml min-1 and a sample volume of 250 µL was obtained. We achieved an integral, selective and reliable system for the determination of ammonium, which may have applications in continuous monitoring in industrial use such as in the fishing sector, vineyards, wines etc.

In the process of analysis of the supply chain, different approaches can be adopted with the objective of evaluating the factors involved in the process of production-distribution of the final product, where the flows of information and material are involved, one of these approaches corresponds to the simulation tools, in this field of study there have been notable efforts such as the standardization of output data. Tako and Robinson establish that system dynamics simulation is more used at a strategic level compared to discrete simulation, confirming its usefulness in decision making and the analysis of the feedback effect of the system.
Neural mediation of greed personality trait on economic risk-taking

Dispositional greed, characterized by the insatiable hunger for more and the dissatisfaction for not having enough, has often been associated with heightened impulsivity and excessive risk-taking. Despite its far-reaching implications in social sciences and economics, however, the exact neural mechanisms of how greed personality influences risk-taking are still ill understood. In the present study, we showed the correlation between subject’s greed personality trait (GPT) score and risk-taking was selectively mediated by individual’s loss aversion, but not risk attitude. In addition, our neuroimaging results indicated that gain and loss prospects were jointly represented in the activities of the ventral striatum and medial orbitofrontal cortex (mOFC). Furthermore, mOFC responses also encoded the neural loss aversion signal and mediated the association between individual differences in GPT scores and behavioral loss aversion. Our findings provide a basis for understanding the specific neural mechanisms that mediate the effect of greed personality trait on risk-taking behavior.

Iron and heme play central roles in the production of red blood cells, but the underlying mechanisms remain incompletely understood. Heme-regulated eIF2α kinase (HRI) controls translation by phosphorylating eIF2α. Here, we investigate the global impact of iron, heme, and HRI on protein translation in vivo in murine primary erythroblasts using ribosome profiling. We validate the known role of HRI-mediated translational stimulation of integratedstressresponse mRNAs during iron deficiency in vivo. Moreover, we find that the translation of mRNAs encoding cytosolic and mitochondrial ribosomal proteins is substantially repressed by HRI during iron deficiency, causing a decrease in cytosolic and mitochondrial protein synthesis. The absence of HRI during iron deficiency elicits a prominent cytoplasmic unfolded protein response and impairs mitochondrial respiration. Importantly, ATF4 target genes are activated during iron deficiency to maintain mitochondrial function and to enable erythroid differentiation. We further identify GRB10 as a previously unappreciated regulator of terminal erythropoiesis.
Gender Differences in Sexual Health Knowledge Among Emerging Adults in Acute-Care Settings

Published: April 2019

Context

Emerging adults (aged 18-25 years) are increasingly seeking evaluation in acute-care clinics for sexual health–related concerns to receive treatment and education.

Objective

To assess the sexual health knowledge of emerging adult patients by gender at acute-care health centers.

Methods

A prospective, self-administered survey was distributed from August 2014 through May 2016 to patients aged 18 to 24 years who presented to 1 of 4 acute-care locations in a university town in a mid-Atlantic state. Analyses included descriptive statistics, as well as χ2 and Fisher exact test crosstabulations to determine differences between genders.

Results

A total of 388 patients aged 18 to 24 years responded to the survey, with 81% of the sample identifying themselves as students and 64% identifying as female. Women were more likely than men to state that they sought sexual health advice at an urgent-care or walk-in clinic (70.3% vs 52.1%; P<.05). Human papillomavirus knowledge among women was significantly greater than among men (P<.0001). Open-ended responses were widespread and often incorrect, specifically with regard to the human papillomavirus vaccine and routine testing for sexually transmitted infections.

Conclusion

Women were more knowledgeable about sexual health than men. However, both genders were not as knowledgeable overall on sexual health topics as hypothesized. A stronger emphasis on gender-specific programming for sexual health education via community- and school-based programs throughout adolescence, supplemented with greater emphasis on routine preventive health care during adolescence and emerging adulthood, is encouraged.
Impact of Dietary Pattern on Nutritional Status of Pregnant Women in Low and High Strata between the Age Group of 30-39 Years in Mumbai
Authors: Tailor Vaibhavi P. , Sengupta Rupali
Published: April 2019

Background: Maternal Nutrition plays an important role in shaping the mother’s and fetal health. Therefore intake of high salt, high fat, high sugar in the diet might lead to over nutrition among pregnant women due to varied food choices of the since most of the subjects consumed outside food, Sugar Sweetened Beverages such as (Cola, Pepsi, Thumps Up, Soda, Sherbet etc), Processed Food such as (Ready to eat food, Mayonnaise, Cheese spread etc) which consist of increase amount of preservative which might affect the mother and foetal’s health. Since there was increase intake of above food groups and decrease intake of macro and micronutrients in the diet through food group such as Fruits, Nuts and Oilseed, Green Leafy Vegetables etc. Therefore there might be increased risk of Over nutrition among women which might lead to GDM (Gestational Diabetes Mellitus), IUGR (Intra Uterine Growth Retardation), Low Birth weight etc.

Aim: To study the impact of dietary pattern on Nutritional of pregnant women in Low and High Strata.

Method: A purposive random sampling was done among pregnant women because only 2nd trimester pregnant women were selected for the study. The 50 subjects were divided into LSES (Lower Socioeconomic Strata) &HSES (Higher Socioeconomic Strata) on the basis of Kuppuswamy Index. The dietary pattern of the subjects was assessed through FFQ (Food Frequency Questionnaire) & 3 Day Diet Recall.

Result: There was increase consumption of High Fat, High Salt, High Sugar in the diet through consumption if food group such as Outside Food, Processed Food, Sugar Sweetened Beverages etc and in comparison the consumption of Macro and Micronutrient rich food group was lower which included Fruits, Green Leafy Vegetables, Nuts and oilseed etc. In Lower Strata the consumption of above food group was low because they were financially not stable therefore they were given additional services where the company paid their ration balance so that they could consume selective food group which were costing comparatively more. Since the RDA(Recommended Dietary Allowances) requirements were not met therefore the women were prescribed Iron, Calcium and Folic Acid supplements in the diet to decrease the risk of Maternal and fetal complication such as GDM(Gestational Diabetes Mellitus), NTD(Neural Tube Defect), IUGR(Intra Uterine Growth Retardation) etc.

Conclusion: Therefore to decrease the risk of Maternal and Fetal Complications intake of Macro and Micro nutritions in the diet is imperative and it is important to organize Nutrition Intervention programmes and counsel the pregnant women about Maternal Nutrition and how decrease intake of Nutrients in the diet might lead to Maternal Under nutrition and over nutrition and its related risk.
