Authors: Jiménez Alejandro , Saikia Panchali , Giné Ricard , Avello Pilar , Leten James , Liss Lymer Birgitta , Schneider Kerry , Ward Robin
Published: March 2020

Water governance has emerged as an important topic in the international arena and is acknowledged to be a crucial factor for adequate and sustained progress towards achieving Sustainable Development Goal (SDG) 6. However, there is not enough clarity about the practical meaning of the term “water governance” and how to work with it. This paper reviews the term’s use, to reveal how the concept is understood, referred to, and implemented in practice by different stakeholders. Based on literature review and consultations with experts, we identify and describe the core components of water governance (functions), describe their potential qualities when performed (attributes), and how they interrelate with the values and aspirations of the different stakeholders to achieve certain outcomes. These different components are described in detail to construct an operational framework to assess and work with water governance, which covers water and sanitation services delivery, water resources management and transboundary waters. This paper’s findings provide practical guidance for decision makers and practitioners on how action-oriented water governance processes can be meaningfully designed, and ultimately, how to strengthen efforts aiming to improve water governance.

CFD Modeling of Effluent Discharges: A Review of Past Numerical Studies
Authors: Mohammadian Abdolmajid , Kheirkhah Gildeh Hossein , Nistor Ioan
Published: March 2020

Effluent discharge mixing and dispersion have been studied for many decades. Studies began with experimental investigations of geometrical and concentration characteristics of the jets in the near-field zone. More robust experiments were performed using Laser-Induced Fluorescence (LIF) and Particle Image Velocimetry (PIV) systems starting in the 20th century, which led to more accurate measurement and analysis of jet behavior. The advancement of computing systems over the past two decades has led to the development of various numerical methods, which have been implemented in Computational Fluid Dynamics (CFD) codes to predict fluid motion and characteristics. Numerical modeling of mixing and dispersion is increasingly preferred over laboratory experiments of effluent discharges in both academia and industry. More computational resources and efficient numerical schemes have helped increase the popularity of using CFD models in jet and plume modeling. Numerous models have been developed over time, each with different capabilities to facilitate the investigation of all aspects of effluent discharges. Among these, Reynolds-averaged Navier-Stokes (RANS) and Large Eddy Simulations (LES) are at present the most popular CFD models employing effluent discharge modeling. This paper reviews state-of-the-art numerical modeling studies for different types and configurations of discharges, including positively and negatively buoyant discharges, which have mostly been completed over the past two decades. The numerical results of these studies are summarized and critically discussed in this review. Various aspects related to the impact of turbulence models, such as k-ε and Launder-Reece-Rodi (LRR) models, are reviewed herein. RANS and LES models are reviewed, and implications for the simulation of jet and plume mixing are discussed to develop a reference for future researchers performing numerical investigations on jet mixing and dispersion.
Developing a Modified Umbrella Index for Conservation of Macroinvertebrate Diversity in Taizi River Basin, China
Authors: Gao Xin , Ding Hai-yu , Xia Rui , Wang Hui , Kou Qian-qian , Ding Sen
Published: March 2020

Conservation strategies for a reliable set of umbrella species should benefit many co-occurring species and will improve conservation efficiency. The umbrella index (UI) is increasingly applied for umbrella species selection in different ecosystems. We developed a modified river UI to select potential macroinvertebrate umbrella species with a combination of 69 sites in the Taizi River Basin of northeast China. Calculation of UI and comparison of biotic indices between sites of presence and absence of umbrella species were performed to make the final umbrella species list. The umbrella scheme, based on the proportion and composition of sites supporting the confirmed umbrella species, was introduced to illustrate the conservation effectiveness. A total of eight umbrella species were obtained and all of them were aquatic insects, such as caddisfly and mayfly larva. Umbrella schemes supporting the top umbrella species, hosted the majority of co-occurring species and only 7% of beneficiary species were missed by the umbrella schemes of 70% effort. The positive relationship between abundance of co-occurring species and umbrella species, validated the ability of umbrella species to confer protection and co-existence of co-occurring species, and thus indicated the effectiveness of umbrella species conservation. Co-occurring species were located close to umbrella species in ordinations, suggesting they respond to similar environmental variables characterized by high flow velocity, dissolved oxygen and pebble-covered substrate. On account of good performance of umbrella schemes in our study, UI with further improving methods should be promoted for selection of umbrella species and decision for optimizing of conservation sites in the future.

Published: March 2020

The effectiveness of adding compost and the plant Medicago sativa in improving the quality of a soil historically contaminated by polychlorinated biphenyls (PCBs) was tested in greenhouse microcosms. Plant pots, containing soil samples from an area contaminated by PCBs, were treated with the compost and the plant, separately or together. Moreover, un-treated and un-planted microcosms were used as controls. At fixed times (1, 133 and 224 days), PCBs were analysed and the structure (cell abundance, phylogenetic characterization) and functioning (cell viability, dehydrogenase activity) of the natural microbial community were also measured. The results showed the effectiveness of the compost and plant in increasing the microbial activity, cell viability, and bacteria/fungi ratio, and in decreasing the amount of higher-chlorinated PCBs. Moreover, a higher number of α-Proteobacteria, one of the main bacterial groups involved in the degradation of PCBs, was found in the compost and plant co-presence.

Published: March 2020

In green roofs, the use of plant species that withstand dry arid environmental conditions and have reduced water requirements is recommended. The current study presents the effect of irrigation amount on the growth of four different species of lavender; Lavandula angustifolia, Lavandula dentata var. candicans, Lavandula dentata var. dentata, and Lavandula stoechas established on an extensive green roof system and used in urban agriculture. Two irrigation treatments (high and low) determined by the substrate hydraulic properties were applied. Plant growth studied at regular intervals included measurements of plant height, shoot canopy diameter, plant growth index, shoot dry weight and stomatal conductance. The results were consistent and showed that low irrigation reduced plant growth. With the exception of L. stoechas, the appearance of plants watered with the low irrigation treatment was satisfactory, and their use under low water amount irrigation is supported. Interspecies differences among lavender species were present in both irrigation treatments. Overall, L. dentata var. candicans showed the greatest growth, followed in descending order by L. dentata var. dentata and L. angustifolia. In parallel, for stomatal conductance, L. dentata var. candicans showed the lowest value, similar to L. dentata var. dentata, and L. angustifolia the largest. Differences in plant characteristics and size among the latter three species can be considered in the design of extensive green roof systems. The use of substrate hydraulic properties was shown to be important for irrigation management on extensive green roof systems.
Drought Victims Demand Justice: Politicization of Drought by Farmers in Southern Germany over Time
Authors: Müller Wibke
Published: March 2020

Farmers have an important role in problematizing and politicizing drought. Following the argumentative turn in policy analysis, the paper analyzes the process of problem definition by means of a framing analysis, zooming in on four major drought events covered in German farming sector journals that are published by farmers’ associations. The article compares the framing of the four most-cited drought events—1947, 1975–76, 2003, and 2011–12—in order to better understand how problematization has changed over time, and how farmers justify and rationalize calls for political action. Three research questions are answered: What problems are named by farmers journals when describing drought events, and what solutions are proposed? Who is considered responsible for problems and solutions? How has framing of drought changed over time? The paper shows that farmers frame drought as a matter of justice and assert their perceived right to subsidies, compensation, farmer-friendly tax policies, and market regulations by the state. From 2003, drought has been framed in association with climate change. The data findings suggest that there is no post-productivist, post-exceptionalist paradigm shift connected to proposed drought policy solutions. Drought framings appear to be persistent, giving priority to assured farmers’ incomes, not water distribution. Considering the lobby power of farmers’ associations in Germany, this finding helps to understand why state interventions remain the same over time.
Automatic Surface Water Mapping Using Polarimetric SAR Data for Long-Term Change Detection
Authors: Zhang Wen , Hu Baoxin , Brown Glen S.
Published: March 2020

Mapping the distribution and persistence of surface water in a timely fashion has broad value for tracking dynamic events like flooding, and for monitoring the effects of climate and human activities on natural resource values and biodiversity. Traditionally, surface water is mapped from optical imagery using semi-automatic approaches. However, this process is time-consuming and the accuracy of results can vary among image interpreters. In recent years, Synthetic Aperture Radar (SAR) images have been increasingly used. Microwave signals sensitive to water content make SAR systems useful for mapping surface water, saturated soils, and flooded vegetation. In this study, a fully automatic method based on robust stepwise thresholding was developed to map and track the change in the extent of surface water using Polarimetric SAR data. The application of this method in both Radarsat-2 and Sentinel-1 data in central Ontario, Canada demonstrates that the developed robust stepwise thresholding approach could facilitate rapid mapping of open water areas with a promising accuracy of over 95%. In addition, the time-series extent of surface water extracted from May 2008 to August 2016 reveals the dynamic nature of surface inundation, and the trend was consistent with the local precipitation data.
Ocean Exchange and Circulation
Authors: Gačić Miroslav , Bensi Manuel
Published: March 2020

The great spatial and temporal variability, which characterizes the marine environment, requires a huge effort to be observed and studied properly since changes in circulation and mixing processes directly influence the variability of the physical and biogeochemical properties. A multi-platform approach and a collaborative effort, in addition to optimizing both data collection and quality, is needed to bring the scientific community to more efficient monitoring and predicting of the world ocean processes. This Special Issue consists of nine original scientific articles that address oceanic circulation and water mass exchange. Most of them deal with mean circulation, basin and sub-basin-scale flows, mesoscale eddies, and internal processes (e.g., mixing and internal waves) that contribute to the redistribution of oceanic properties and energy within the ocean. One paper deals with numerical modelling application finalized to evaluate the capacity of coastal vegetated areas to mitigate the impact of a tsunami. The study areas in which these topics are developed include both oceanic areas and semi-enclosed seas such as the Mediterranean Sea, the Norwegian Sea and the Fram Strait, the South China Sea, and the Northwest Pacific. Scientific findings presented in this Special Issue highlight how a combination of various modern observation techniques can improve our understanding of the complex physical and biogeochemical processes in the ocean.

Published: March 2020

На основании проведенного исследования изменений генотипической структуры, динамики уровня продуктивности и численности подконтрольного поголовья коров ярославской породы в стране в целом и в ведущих регионах ее разведения за 15 лет сделан вывод о необходимости кардинальных изменений в стратегии селекционной работы в породной популяции для ее улучшения и сохранения от исчезновения в ближайшие 1015 лет. В качестве оптимальной кровности у помесных животных при скрещивании ярославской и голштинской пород обоснован рубеж в 50 по обеим породам, достижение которого возможно всего лишь в течение 12 поколений за счет отказа в современной популяции от использования в племенном подборе чистопородных голштинских производителей, от разведения в себе помесей с кровностью по голштинам 7587,5 и от дальнейшего поглотительного скрещивания с заменой названных методов подбора и разведения на вводное и возвратное виды скрещивания с использованием голштино-ярославских быков-производителей с кровностью 50 по обеим породам.

On the basis of the study of changes in genotypic structure, the dynamics of productivity and size controlled by the number of cows of the Yaroslavl breed in the country and in major regions of its cultivation for 15 years the conclusion is made about necessity of cardinal changes in the strategy of breeding work in pedigree populations to improve and preserve from extinction in the next 10-15 years. As the optimal genotype for crossbreeding between Yaroslavl and Holstein breeds, the 50 threshold for both breeds is justified, which can be achieved only within 1-2 generations due to the refusal in the modern population to use purebred Holstein producers in breeding selection, from breeding in itself crossbreeds with the genotype of Holstein 75-87. 5 and from further absorption crossing with the replacement of the above methods of selection and breeding for introductory and return types of crossing using Holstein-Yaroslavl bulls with the genotype of 50 for both breeds.

Published: March 2020

Today, there are different interventional approaches for patients undergoing ST elevation myocardial infarction (STEMI) with multiple vessel diseases. Objectives: to compare the mid-term results of two strategies of myocardial revascularization used for the management of patients with STEMI with multiple vessel diseases. Material and methods: we analyzed retrogradely 64 profiles of patients diagnosed STEMI with multiple vessel diseases on coronary angiography and underwent angioplasty in Cardiovascular department from 5/2013 – 1/2014. The patients had been divided into 2 groups: group 1 (percutaneous coronary intervention (PCI) of the sole Infarct-related artery followed by medical therapy, n=33) and group 2 (staged PCI in STEMI patients with multiple vessel diseases, n=31). Results: group 2 had comparable combined end-points (death + Myocardial infarction + revascularization) rate but higher rate of detection of significantly stenosed non-culprit vessels than those of group 1. Conclusion: for the STEMI patients with multiple vessel diseases admitted to Hue University hospital, staged PCI was better than PCI of the sole infarct-related artery in term of omitting less patients who were appropriate for revascularization (these patients had no indication for coronary artery bypass graft). However, these two approaches had no statistical difference regarding to major adverse cardiac events.

ASSESSING THE ROLE OF ACOUSTIC RADIATION FORCE IMPULSE IMAGING TO PREDICT THE STAGING OF LIVER FIBROSIS IN PATIENTS WITH NONALCOHOLIC STEATOHEPATITIS
Authors: Tran Thi Khanh Tuong , Hoang Trong Thang , Vo Thi Xuan Hanh
Published: March 2020

Background/Objectives: Acoustic radiation force impulse (ARFI) is a novel non-invasive technology for the assessment of stages of liver fibrosis in chronic hepatic disease. Some studies previously reported that ARFI is a promising method for assessing liver ﬁbrosis in patients with NAFLD/NASH. This study aimed to validate the diagnostic usefulness of ARFI for prediction of staging of liver fibrosis in patients with NASH. Patients and Methods: The study was carried out on 51 patients with NASH. All of patients underwent a liver biopsy for histological assessment of liver fibrosis and ARFI elastography. Cut-off values were determined using receiver-operating characteristic (ROC) curves. Results: Histological liver fibrosis was evaluated by Metavir scoring; F0: 8 cases, F1: 29 cases, F2: 10 cases and F3: 4 cases. ARFI quantification correlated significantly with the fibrosis stage (Spearman rho: 0.44, p <0.05). The areas under the ROC curves (AUROC) were 0.75 (95% confidence intervals: 0.60-0.90) for ≥F2 and 0.78 (0.53-0.99) for F3. The cut-off values of the shear wave velocity (SWV) were as follows: ≥1.29 m/s for ≥F2 (sensitivity 64.3%, specificity 83.8%, PPV 60% and NPV 86.1%), ≥ 1.38 m/s for F3 (sensitivity 75%, specificity 89.4%, PPV 57.5%, NPV 97.7%). Conclusions: Increasing ARFI velocities correlate with high degree of liver fibrosis. ARFI has quite good accuracy and high specificity, NPV for prediction of significant and advanced fibrosis in patients with NASH. The method should be employed routinely in the workup of patients with NASH to exclude the presence of significant and advanced liver fibrosis. Key words: liver fibrosis, liver stiffness, non-alcoholic fatty liver disease (NAFLD), nonalcoholic steatohepatitis (NASH), acoustic radiation force impulse imaging (ARFI).

New method of thermoplastic materials turning
Authors: Erenkov O. Yu.
Published: March 2020

The theoretical and experimental research results of the new method for polymeric materials turning are presented. A distinctive feature of the developed method is the preliminary deformation of the material by twisting the workpiece.. It is theoretically shown that the maximum stresses value during twisting is formed on the workpiece surface layer. It has been experimentally proved that the workpiece deformation by twisting leads to changes in the stress-strain state of the polymer chain. The workpiece predeformation by twisting allows to obtain a higher quality surface layer compared to traditional turning.

Scores obtained from the Revised Two Factor Study Process Questionnaire (R-SPQ-2F) are regularly used in Higher Education to profile students as being Deep or Surface learners. Despite its utility, concerns about its validity have been mounting. Possible factor models have been tested---guided by the original theorising---yet consensus has not been achieved over what is a permissible representation. This study builds on this by seeking to answer a single research question of identifying the best factor model for the R-SPQ-2F. Using data collected from a final sample of 1,158 students, three models were tested using both Exploratory Structural Equation Modelling and Confirmatory Factor Analysis. Findings supported the original decomposition into four factors; however, this came at a cost of distorting factor definitions. A discussion of where these distortions arose and how they can be addressed is offered.

Worldwide CO2 emission has been done by various agencies and reported their roots. The one most emerging and well known contributor of CO2 emission is the cement manufacturing. Now a days, cement manufacturing work out in practice are 1.7 x 109 t/year and it creates 7-8% worldwide greenhouse gas emission. Where the infrastructural growth depends on concrete production and concrete making process needs the binder material as a cement. Cement production has produces 900kg of CO2 per thousand kilogram of cement consumption and it’s definitely doubled in 2050, if other binder material inventions not happened. Therefore as considering a crucial role of binder material, fly ash material can play same or partial role as alternative material to cement. This study mainly introduces fresh fly ash concrete behavior for sustainable adoptability. Fly ash concrete more feasible (cheaper), scale down permeability, boost strength and influence other concrete properties. This paper is useful for assessing workability issues by providing 54 test results of slump cone and compaction factor test.

Switched Reluctance motors are very demanding among all type of motor due to its simple construction. Feedback circuit (control circuit) and design of Switched Reluctance Motor (SRM) require information of its parameters, like inductance, flux linkage and torque. High torque, high reliability and cheap manufacturing cost are the attractive features of the SR motors. In this paper we have simulated SR motor with initial design, teethed stator pole and multi-teethed stator pole using COMSOL multi-physics CAD software. We have plotted inductance profile and static torque characteristics which shows that the static torque characteristics has peak value with sharp reduction in torque in intermediate position with teethed stator pole, that can be overcome by using multi-teeth stator pole with compromising in maximum torque.

With the large spread of wrist worn smart devices in day-to-day lives, an extensive series of applications are enabled. Securing message conversation between these devices has become a challenging issue, considering the high security necessities and low computation abilities of these wrist worn devices. In this paper, we propose a secure wrist worn smart device coupling arrangement by manipulating the wave indication of the strategies generated by the handshake to barter a trustworthy key between users. To guarantee the safety of key negotiation, a hybrid secured algorithm is further developed. On Comparing with existing algorithms, the planned algorithm evades complicated fault alteration algorithms. In existing work the key generation is small in size so it is easy to detect by the intruder, in order to overcome this issue the RSA algorithm is combined with the AES algorithm, So that the size of the key is increased due to the combined algorithm and therefore robustness of the key is increased compared to the existing method. Investigational results are provided, which prove that the proposed handshake acceleration-based coupling arrangement is strong, safe, and effectual.
