Published: September 2020

The physics of heat and mass transfer from an object in its wake has significant importance in natural phenomena as well as across many engineering applications. Here, we report numerical results on the population density of the spatial distribution of fluid velocity, pressure, scalar concentration, and scalar fluxes of a wake flow past a sphere in the steady wake regime (Reynolds number 25 to 285). Our findings show that the spatial population distributions of the fluid and the transported scalar quantities in the wake follow a Cauchy-Lorentz or Lorentzian trend, indicating a variation in its sample number density inversely proportional to the squared of its magnitude. We observe this universal form of population distribution both in the symmetric wake regime and in the more complex three dimensional wake structure of the steady oblique regime with Reynolds number larger than 225. The population density distribution identifies the increase in dimensionless kinetic energy and scalar fluxes with the increase in Reynolds number, whereas the dimensionless scalar population density shows negligible variation with the Reynolds number. Descriptive statistics in the form of population density distribution of the spatial distribution of the fluid velocity and the transported scalar quantities is important for understanding the transport and local reaction processes in specific regions of the wake, which can be used e.g., for understanding the microphysics of cloud droplets and aerosol interactions, or in the technical flows where droplets interact physically or chemically with the environment.
Bedside Coagulation Tests in Diagnosing Venom-Induced Consumption Coagulopathy in Snakebite
Authors: Wedasingha Supun , Isbister Geoffrey , Silva Anjana
Published: September 2020

Venom-induced consumption coagulopathy is the most important systemic effect of snake envenoming. Coagulation tests are helpful to accurately and promptly diagnose venom-induced consumption coagulopathy and administer antivenom, which is the only specific treatment available. However, bedside clotting tests play a major role in diagnosing coagulopathy in low-income settings, where the majority of snakebites occur. We conducted a literature search in MEDLINE® from 1946 to 30 November 2019, looking for research articles describing clinical studies on bedside coagulation tests in snakebite patients. Out of 442 articles identified, 147 articles describing bedside clotting assays were included in the review. Three main bedside clotting tests were identified, namely the Lee–White clotting test, 20-min whole blood clotting time and venous clotting time. Although the original Lee–White clotting test has never been validated for snake envenoming, a recently validated version has been used in some South American countries. The 20-min whole blood clotting time test is the most commonly used test in a wide range of settings and for taxonomically diverse snake species. Venous clotting time is almost exclusively used in Thailand. Many validation studies have methodological limitations, including small sample size, lack of case-authentication, the inclusion of a heterogeneous mix of snakebites and inappropriate uses of gold standard tests. The observation times for bedside clotting tests were arbitrary, without proper scientific justification. Future research needs to focus on improving the existing 20-min whole blood clotting test, and also on looking for alternative bedside coagulation tests which are cheap, reliable and quicker.

Published: September 2020

This study proposes a generalized framework for the assessment of flood risk and potential strategies to mitigate flood under various vulnerability and adaptation scenarios. The possible causes of hazard, exposure and vulnerability in flood disaster were clearly identified by using a climate risk template. Then, levels of exposure and vulnerability with adaptive capacity and sensitivity were further defined by a quantification approach, and the climate risk maps were consequently provided. The potential possible climate adaptation strategies were investigated through the comparison of climate risk maps with diverse adaptation options. The framework was demonstrated in the Kyoto City in Japan with residents as a target population to reduce the flood risk. The results indicate that the government should pay attention to reducing the population in flood-prone areas and adopt diverse adaptation strategies to reduce the flood risk to the residents. Rainwater storage and green roofs as adaptation strategies as short-term planning options are recommended. The construction of detention ponds has been suggested to prevent flood risks in future as a part of the long-term planning process. In conclusion, the proposed framework is expected to be a suitable tool for supporting climate risk analysis in the context of flood disasters.
Resilience Viewed through the Lens of Climate Change and Water Management
Authors: Wilby Robert L.
Published: September 2020

Resilience is not a new idea but there has been an upsurge in efforts to operationalize the concept within water management. This review begins with a synopsis of related themes around persistent and emerging pressures on freshwaters; environmental thresholds (or tipping points); ‘safe’ operating conditions; multiple stable states; regime shifts. A case is made for viewing and managing the resilience of water systems at nested scales. Indicators are needed to track evolving climate risks as well as to measure socio-ecological responses. Catchment properties can identify those river systems that are more or less likely to return to a pre-disturbance state; resilience further depends on institutional and social landscapes. Ideally, allied notions of resistance and reliability are applied alongside resilience to broaden the portfolio of adaptation measures. Water managers would also benefit from more consistent use of resilience terminology; incentives to build back better after catastrophes; strategic monitoring of incipient threats and tipping points; availability of long-term adaptation indicators; coordinated efforts to reduce non-climatic pressures on freshwaters (especially in headwaters); evidence-based, practical guidance on adaptation measures that build resilience.
Reactive Silica Traces Manure Spreading in Alluvial Aquifers Affected by Nitrate Contamination: A Case Study in a High Plain of Northern Italy
Authors: Severini Edoardo , Bartoli Marco , Pinardi Monica , Celico Fulvio
Published: September 2020

In the northern sector of the Po River Plain (Italy), widespread intensive agriculture and animal farming are supported by large amounts of water from Alpine lakes and their emissaries. Flood irrigation and excess fertilization with manure affect both the hydrology and the chemical quality of surface and groundwater, resulting in diffuse nitrogen pollution. However, studies analyzing the mechanisms linking agricultural practices with vertical and horizontal nitrogen paths are scarce in this area. We investigated groundwater quality and quantity in an unconfined, coarse-grained alluvial aquifer adjacent to the Mincio River (a tributary of the Po River), where steep summer gradients of nitrate (NO3−) concentrations are reported. The effects of manure on solutes’ vertical transport during precipitation events in fertilized and in control soils were simulated under laboratory conditions. The results show high SiO2 and NO3− leaching in fertilized soils. Similarly, field data are characterized by high SiO2 and NO3− concentrations, with a comparable spatial distribution but a different temporal evolution, suggesting their common origin but different processes affecting their concentrations in the study area. Our results show that SiO2 can be used as a conservative tracer of manure spreading, as it does not undergo biogeochemical processes that significantly alter its concentrations. On the contrary, nitrate displays large short-term variations related to aquifer recharge (i.e., flood irrigation and precipitation). In fact, aquifer recharge may promote immediate solubilization and stimulate nitrification, resulting in high NO3− concentrations up to 95.9 mg/L, exceeding the Water Framework Directive (WFD) thresholds. When recharge ends, anoxic conditions likely establish in the saturated zone, favoring denitrification and resulting in a steep decrease in NO3− concentrations.

Published: September 2020

Gold mining uses chemicals that are discharged into rivers without any control when there are no good mining practices, generating environmental and public health problems, especially for downstream inhabitants who use the water for consumption, as is the case in Monterrey township, where the Boque River water is consumed. In this study, we evaluate Boque River water quality analyzing some physicochemical parameters such as pH, heavy metals, Hg, and cyanide; bioassays (Lactuca sativa, Hydra attenuata, and Daphnia magna), mutagenicity (Ames test), and microbiological assays. The results show that some physicochemical parameters exceed permitted concentrations (Hg, Cd, and cyanide). D. magna showed sensitivity and L. sativa showed inhibition and excessive growth in the analyzed water. Mutagenic values were obtained for all of the sample stations. The presence of bacteria and somatic coliphages in the water show a health risk to inhabitants. In conclusion, the presence of Cd, Hg, and cyanide in the waters for domestic consumption was evidenced in concentrations that can affect the environment and the health of the Monterrey inhabitants. The mutagenic index indicates the possibility of mutations in the population that consumes this type of water. Bioassays stand out as an alert system when concentrations of chemical contaminants cannot be analytically detected.

Published: September 2020

Along with the global climate change, gully erosion, flood and drought jointly restrict the sustainable development of arid rangeland in Central Asia. Rainwater harvesting (RWH) system in gully is a flexible practice that alleviate complex environmental problems. In the Kulusitai watershed of Xinjiang, China, our study presented a decision-making system using GIS combined with multi-criteria analysis and a field survey to identify suitability of gully for RWH. The results showed that nearly 40% of rangeland belonged to high runoff potential area, and gullies as the runoff collection channel became the potential site of RWH. The selection of RWH systems depended on catchment environment and gully characteristics. Therefore, based on the unique natural conditions of Xinjiang and successful RWH cases in other regions, we discussed some suitable low-cost RWH techniques to restore degraded grassland and promote community development. Our study will provide some suggestions for ecological restoration and pasture management in arid regions of Central Asia.
Geomorphic Approaches to Estimate Short-Term Erosion Rates: An Example from Valmarecchia River System (Northern Apennines, Italy)
Authors: Guerra Veronica , Lazzari Maurizio
Published: September 2020

Studying fluvial dynamics and environments, GIS-based analyses are of fundamental importance to evaluate the network geometry and possible anomalies, and can be particularly useful to estimate modifications in processes and erosion rates. The aim of this paper is to estimate short-term erosion rates attributable to fluvial processes in two sample catchment sub-basins of the Marecchia river valley, by conducting quantitative morphometric analyses in order to calculate various descriptive parameters of the hierarchisation of the river networks and the mean turbid transport of streams (Tu). Sediment yield transported by streams can in fact partially express the amount of erosional processes acting within the drainage basin. The study area includes two sub-basins of the Marecchia valley (Senatello river, 49 km2 and Mazzocco river, 47 km2), chosen because of their similar extent and of the different location in the major catchment basin. Starting from geomorphological maps of the two river basins, the Tu parameter has been calculated and converted in short-term rate (average value 0.21 mm/year). Moreover, the comparison of these short-term mean data with the uplift rates calculated on a regional scale (0.41 ± 0.26 mm/year) in the Marecchia valley confirms that the northern Apennines may represent a non-steady state system.

Sutiles corrosiones: crítica a las domesticidades femeninas en la obra Insertion H-Kupfer Intra-Uterine de Silvia Gai
Authors: Blaconá Cynthia , Rodríguez Jimena
Published: September 2020

El presente artículo propone una aproximación a la obra Insertion H-Kupfer Intra-Uterine (1995) de la artista argentina Silvia Gai. En los años 90, Gai comenzó a trabajar con el bordado y el tejido, procedimientos asociados tradicionalmente a las denominadas “labores femeninas”. De este modo, recuperaba el legado de los feminismos estadounidenses de los años 70, que buscaron revalorizar dichas prácticas para poner en cuestión la distribución sexuada de los materiales, las técnicas, los saberes y los espacios, dentro de los órdenes público y privado. A partir de una materialidad basada en las labores de aguja y de una operación visual corrosiva, que pone en conjunto el delantal como símbolo del ámbito doméstico y los órganos femeninos con dispositivos de uso anticonceptivo, Gai propone una sutil y crítica reflexión acerca del género, la sexualidad, la procreación y el aborto. En esta dirección, la autora retomaba también el legado de las artistas feministas argentinas quienes, en los 80‟s, introdujeron estas problemáticas aún tan espinosas en nuestro campo artístico.

This paper introduces an enhanced control system to improve the transient response of the dynamic voltage restorer (DVR). The control strategy achieves superior response against voltage disturbance approximately within 400 μs. The control system comprises three terms: closed-loop feedback control signal, upstream disturbance detection error, and voltage drop over DVR term. The actual load voltage is compared with its reference value and is adapted by a PI controller. The upstream disturbance detection significantly enhances the transient time of the control system performance and improves its steady-state operation. In addition, the voltage drop over the DVR term represents the voltage drop caused by the DVR circuit component. Incorporating these effects in the control loop, fast and accurate response of the system are achieved. An L filter is used instead of the LC filter to overcome the inherent LC filter damping delay and resonance problem mentioned in previous studies. The system is simulated using MATLAB/ Simulink. The simulation results show excellent response in transient and steady-state operation for various operating conditions.

Recent advancement in digital technology and vast use of social image sharing websites leads to a huge database of images. On social websites the images are associated with the tags or keywords which describe the visual content of the images and other information. Theses tags are used by social image sharing websites for retrieval of the images. Therefore, it is important to assign appropriate tags to the images. To assign related tags, it is necessary to choose appropriate classifier for automatic classification of images into various sematic categories with respect to the classification accuracy which is important step for image tag recommendation. In this paper, three supervised classifier algorithms are implemented for image classifications which are SVM, kNN and random forest and its performance is analyzed on Flickr images. For classification of images, the features are extracted using color moment and wavelet packet descriptor.

Authors: Ehigie Adeola F. , Okonji Raphael E. , Ojeniyi Fiyinfoluwa D. , Jesulade Mary O. , Ehigie Leonard O.
Published: September 2020

Background: 3-Mercaptopyruvate sulfurtransferase (3-MST) is a multifunctional, mitochondrial and cytoplasmic sulphurtransferase that catalyses the detoxification of cyanide to a less toxic thiocyanate. Limicolaria flammea feeds majorly on green leaves, plants and other cyanide containing foods.
Methods: 3-MST from the hemolymph of Limicolaria flammae was purified by 70 % ammonium sulphate precipitation and ion exchange chromatography. The purified enzyme was characterized at different levels such as optimal activity, inhibitors, substrate preference, thermal stability and analysis of ki-netic parameters.
Results: 3-MST from the hemolymph of Limicolaria flammae had a yield of 0.75 % with specific activity of 0.42 μ/mg/ml. The Km values for the substrates; KCN and 2-Mercaptoethanol were 1.09 and 2.83 mM, while the Vmax values were 3.08 μml/mol/min and 6.17 μml/mol/min respectively. The optimum pH and temperature of the enzyme were 5.0 and 60° C respectively. The metals (Al3+, Ca2+, and K+) demonstrated inhibitory activity in a concentration dependent manner. The substrate specificity study showed that sodium sulphite, ammonium per sulphate and ammonium sulphite showed enzymatic interference.
Conclusion: This study affirmed the presence of 3-MST activity in the hemolymph of Limicolaria flammea, an indication that the enzyme possesses functional cyanide detoxification mechanism necessary for the survival of the animal in the environment.

Authors: Adeogun Adedayo , Adeoti Caroline
Published: September 2020

Background: Good nutrition is a prerequisite for the national development of countries and for the well-being of every individual. Although problems related to poor nutrition affect the entire population, women and children are especially vulnerable because of their physiological and socio-economic characteristic. Pregnancy places extra nutritional demands on women and this may affect the development of the foetus and its health later in life. The nutritional demands however does not necessarily translate to increase in the amount of food to be consumed but certain nutrients such as protein, iron, folate, zinc and iodine are required in higher proportions to prevent anaemia and abortion. The general objective of this study was to assess the nutritional status of pregnant women aged 15-49 years that were attending antenatal care (ANC) at Primary Healthcare Centres, Odo-Otin Local Govern-ment Area, Osun State, Nigeria.
Methods: This was a cross-sectional descriptive study of 400 pregnant women attending ANC at Primary Health Care Centres in Odo-Otin Local Government Area of Osun State over a period of four weeks. Their anthropometric and bio-chemical data were determined. Their bio-data and dietary investigation were obtained using a question-naire. Analysis was done using Statistical Package for Social Sciences (SPSS) version 20 and P was drawn at 0.05.
Results: One hundred and thirty two (33.3%) of the participants were malnourished with their mid-upper arm circumference (MUAC) less than 23cm. Anaemia was found in 127(31.8%) of participants and of this proportion, civil servants were more commonly affected 54 (42.5%). Of the 90 participants that were civil servants, 46.5% were under-weight and they were the most malnourished while farmers had the least proportion (15.8%) of underweight participants (P=0.001). More than half (51.8%) of those who earned less than N10,000.00 were under-weight compared with 8.3% of those who earned more than N50,000.00 (P=0.001). One hundred and eight (94.7%) of those who skipped meals were under-weight compared to 6.3% of those who do not (P=0.001). Hence, 82.7% of those who skipped meals were anaemic as compared to17.3% of those who do not (P=0.001).
Conclusion: The prevalence of malnutrition among pregnant women in Odo-Otin Local Government Area of Osun State, Nigeria was moderately low. However, it is worth noting that pregnant women who were Civil Servants were more malnourished .

GRADIENT-BASED OPTIMIZATION OF SPACECRAFT AND AIRCRAFT THERMAL DESIGN
Authors: Mačiulis Laurynas , Belevičius Rimantas
Published: September 2020

Steady-case thermal analysis plays an important role in dimensioning thermal control systems for spacecrafts and aircrafts.
Usually a trial and error approach is used based on engineering judgement and experience. When thermal models become complex or there are conflicting
thermal requirements, however, it becomes harder for an engineer to gain insight as to which design decisions will lead to better results. Numerical
optimization, on the other hand, could provide a more robust approach for the thermal design of complex spacecraft or aircraft models. In this paper,
we suggest a gradient-based multidisciplinary optimization of thermal models where the coupled derivatives of the multidisciplinary system are obtained
with the adjoint method. We show that in the case of steady-state thermal analysis, there is an analytic solution of a partial derivatives of implicit
heat-transfer equation that can be used to derive total derivatives of the system. We present a practical application of this method by solving a small
interplanetary spacecraft thermal optimization problem consisting of one objective, 15 design variables, and 10 constraints. We found that by using
gradient-based optimization with exact derivatives, the best results can be achieved by exploring the design space at multiple initial starting points
without major computational overhead.

Published: September 2020

This research aims to investigate whether outsourcing mediates the impact of dynamic strategic capabilities on strategic entrepreneurship.
The population of the research consists of top managers in five stars hotels. A sample of 215 respondents were selected for the research in which 186 questionnaires
were valid for statistical analysis. Structural equation modelling (SEM) was used to test the hypotheses of the research. The results of the research indicate that
outsourcing does not mediate the relationship between dynamic strategic capabilities and strategic entrepreneurship. All the dimensions of dynamic strategic
capabilities have a statistical impact on strategic entrepreneurship, while the dynamic strategic capabilities dimension all affect outsourcing except the seizing
capability. Based on the research results, managers and decision-makers have to focus on innovation functions by enhancing the role of knowledge management and R&D
activities, as well as concentrate on employees training programs.

Published: September 2020

In modern conditions, entrepreneurs are faced with the acute problem of analysing of numerous information, quickly responding to a constantly changing economic situation, and making the most optimal decisions. In this regard, the development of a Business Assistant service (BAS) is a very relevant since it is a modern solution that can significantly simplify and improve the work of enterprises. The main goal of the research is on the basis of AI technologies to elaborate the Business Assistant service, that would speed up, optimize and simplify the decision-making process for the entrepreneur and can be used by many enterprises both when starting a business and when operating it. The main tasks for implementing the goal are: to analyze the scientific literature regarding the possibilities of using AI technologies in business, to identify the factors that mainly influence the entrepreneur’s choice regarding the sphere of activity, as well as the types of information most useful for doing business, to analyze and collect data for the model design, to develop a prototype of the BAS and test its functionality in practice. The research methods are: the theoretical – analysis and synthesis, abstraction method, the empirical – modelling (clustering, classification, logistic regression) and experimental method.The investigation results are: a prototype of the BAS was created, its effectiveness – ability of delivering useful recommendations and improving the business decision-making process for the entrepreneur has been proven experimentally using actual market data. The service can be effectively used by small and medium-sized enterprises in various industries and regions, provided that there is an access to the necessary data. The main risks associated with its implementation and possible ways of their reduction were considered.

The Allen Telescope Array was used to search for signals with characteristics similar to the “Wow” signal, the best candidate for an extraterrestrial radio signal found during Ohio State University’s (OSU’s) seven-year 21 cm 10-kHz channel sky survey for signals possibly due to extraterrestrial intelligence. While previous follow-up searches have reported null results, our observations covered a 5 deg2 field of view that extends well beyond the locus of all consistent directions of arrival (DOAs) of the original signal, and covered a 10 MHz bandwidth four times wider than the widest prior follow-up observations, using 12.8 kHz channels approximating OSU’s 10 kHz resolution. Approximately 100 hours of data were accumulated, considerably more time than any previous follow-up campaigns. We used interferometric imaging with an angular resolution of approximately 007 and automated feature-finding to search for point-like features mimicking a Wow repetition, obtaining single-channel sensitivity of ∼1.2 Jy for one minute averages. This allows identification of the DOA of a very brief repetition, with strong discrimination from radio interference, and eliminates the usual constraint that the signal must persist for long periods of time (around one hour) before the true DOA can be verified (because interfering signals from the horizon sometimes masquerade as coming from the look direction). No point-like features significantly exceeding the noise were found inside the full width at half maximum of the OSU fields of view, although one 26σ point-like feature was detected during one 10 second integration about 1/3° away.
Molecular Clouds Surrounding Supernova Remnant G43.9+1.6: Associated and Nonassociated

Published: September 2020

Many supernova remnants (SNRs) are considered to evolve in molecular environments, but the associations between SNRs and molecular clouds (MCs) are often unclear. Being aware of such ambiguity, in our study, we report on the molecular environment toward SNR G43.9+1.6 through CO line observations. We investigated the correlations between the SNR and MCs at different velocities, and found two velocity components, i.e., ∼5  km s−1 and ∼50  km s−1, showing spatial correlations with the remnant. However, no kinematic evidence of a disturbance was found for the ∼5  km s−1 velocity component. Furthermore, at the distance of the ∼5  km s−1 velocity component, either near or far, the derived physical parameters are unreasonable. We conclude that the SNR is not associated with the ∼5  km s−1 velocity component, and their spatial correlation is just a chance correlation. For the ∼50  km s−1 velocity component, kinematic evidence of disturbances, as well as the spatial correlation, indicate that it is associated with the SNR. We found that all the CO spectra extracted from the molecular clumps distributed along the border of the remnant are with broadened components presented, which can be fitted by Gaussian functions. Through further analysis, we suggest that the SNR is at a near kinematic distance of about 3.1 kpc.

Initial impact of a soil disturbance technique (disc harrowing) on Orthoptera in a grass heath in Breckland, UK
Authors: Gardiner Tim
Published: September 2020

On a Breckland grass heath in eastern England, soil disturbance methods such as disc harrowing employed to benefit endangered plants such as tower mustard, Arabis glabra, could also create exposed ground for localized insects, specifically the mottled grasshopper, Myrmeleotettix maculatus. Orthoptera of disc-harrowed strips on a grass heath at Santon Warren in Norfolk, UK, were monitored in 2018 and 2019. Data analysis focused on two target species, field grasshopper, Chorthippus brunneus, and M. maculatus, which are likely to respond positively to the creation of early successional habitat. Of the two species, M. maculatus was found in significantly high abundance on the disc-harrowed strips, whereas C. brunneus was not. The species richness of Orthoptera did not appear affected by harrowing, although three species at this location (lesser marsh grasshopper, Chorthippus albomarginatus, long-winged conehead, Conocephalus fuscus, and Roesel’s bush-cricket, Roseliana roeselii) need taller vegetation than was present on the disc-harrowed strips.
