Background: Non-edible oil as biodiesel helps to meet the energy demand and to reduce environmental degradation. Jatropha curcas is one of the potential oil yielding plant which can be grown under agroforestry systems without affecting food production. Hence the current study aimed to find out compatible intercrop under J. curcas and optimum spacing of J. curcas for intercropping.
Methods: A study was carried out in three and a half-year old J. curcas plantation. Different spacings of J. curcas viz., 3m × 3m, 4m × 2m and 4m × 3m and different legumes viz., blackgram, greengram, cowpea, groundnut and oilseed crops viz., gingelly and sunflower were evaluated in split plot design.
Result: Growth and yield of intercrops, available soil N, P and uptake of N, P, K by intercrops were significantly higher at wider spacing of J. curcas (4m × 3m). Among the intercrops, groundnut recorded higher uptake of N (67.3 kg ha-1), P (19.9 kg ha-1) and K (65.3 kg ha-1). Groundnut produced a significantly higher yield (885 kg ha-1) followed by cowpea (630 kg ha-1). The study found that planting of J. curcas at 4m × 3m spacing and intercropping with groundnut is a compatible and profitable J. curcas based agroforestry system.

Authors: Yadav Shankar Lal , Ghasolia R. P. , Sharma Jitendra
Published: November 2020

Background: Root rot disease of fenugreek caused by Rhizoctonia solani has become a severe menace to the growers of Rajasthan as well as India. This pathogen survives in soil, causes damping off and root rot symptoms and responsible nearly for 50 per cent disease incidence and yield losses.
Methods: During 2016-17 to 2017-18 cropping seasons, this study was carried out with the aim to manage the disease by means of using six fungicides including newer formulations (hexaconazole and tebuconazole + trifloxystrobin) under in vitro and field conditions.
Result: The result of in vitro study with tebuconazole + trifloxystrobin was found to be most fungitoxic and inhibited mycelial growth cent per cent at 200 and 500 ppm concentrations. Seed treatment with tebuconazole + trifloxystrobin (@ 0.2%) was found highly effective in reducing disease incidence (83.12%) and in increasing seed yield (84.71%) under field conditions. Thus, it can be concluded that the use of newer combined formulation as seed treatment before sowing provide us alternative source to manage root rot disease of fenugreek.

Authors: Chaudhary S. , Dhanker R. , Kumar R. , Goyal S.
Published: November 2020

Background: Legumes are relatively cheap, non-animal good source of valuable proteins, micro-nutrients and vitamins in human and animal nutrition for many years. Recognizing the potential of legumes in achieving the sustainable solution to the global food security, protein access, eradicate hunger and malnutrition, FAO of the United Nations (The Food and Agriculture Organization), facilitated 2016 as the International Year of Pulses (grain legumes) under the banner ‘nutritious seeds for a sustainable future’. The nutrient, nitrogen and biological nitrogen fixation is very crucial for legume’s growth, besides sulphur deficiency is very sensitive to the nodulation and nitrogen fixation. Despite the amazing beneficial properties, legumes are neglected by most of us due to having tough competition with low price and high yielding cereal varieties.
Methods: Therefore keeping in mind the above points, this review discusses the importance and application of legumes in different perspectives, legume cultivation patterns, importance of sulphur nutrition to legumes, role of sulphur oxidizing bacteria in sulphur nutrition, improving soil and environment, challenges and future of legumes.
Conclusion: Legumes have variety of applications including food, health, environment and many other sectors but we are not able to produce enough amount according to their genetic potential due to inefficient breeding programs. Sulphur is an important nutrient along with N effecting its growth and yield. Sulphur oxidizing bacteria (SOB) have been proved as an important tool for improving yield and symbiotic nitrogen fixation in legumes. Therefor application of biofertilizers along with SOB and improved genetic breeding programmes may prove leading steps to enhance their production.
Enforceability of decisions of the Agricultural Paying Agency in matters of direct payments
Authors: Palsova Lucia , Benus Ondrej
Published: November 2020

Since its inception, the Common Agricultural Policy has been the largest among all common European policies. The main objective of the Common agricultural policy is food sovereignty in the European Union, stabilization of farmers' incomes and, at present, support for non-production functions of agriculture and environmental protection. Given the rising input prices and the time mismatch between supply and demand for agricultural products, the first pillar of the CAP has become a key tool for sustaining the desired competitiveness of agricultural products in the EU Member States. Direct payments have become an important tool for Slovak farmers, and therefore their effective implementation is essential for their continued existence or development. The aim of the paper was to point out the weak enforceability of direct payments to eligible users of agricultural land if there is a conflicting legal entitlement to provide a direct payment in accordance with §28 and §29 of Act no. 280/2017 Coll. and the resulting problems for eligible applicants.
Human geography of drylands. I. Planning the database: Physical, built-up, chemical, biological (ecological), and social indicators
Authors: Arvai Matyas , Fekete Karoly , Pasztor Laszlo , Komives Tamas
Published: November 2020

We propose a method based on multilayered mapping for investigating the current problems of people who live in drylands and we urge decision-makers to support such studies to establish the foundations for future decisive and preventive actions. This paper contains an expandable compilation of the environmental indicators (mostly mappable) that may influence the human geography of a certain region. We believe that this geospatial approach may help to resolve convoluted physical, chemical, and social relation­ships and, at the same time, generate a valuable database for further research. The application of the concept, if successful, will give directions to tackle certain contem­porary problems in drylands and predict future ones caused by global climate change.

Authors: ÇELİK Hakan , YÜRÜK BAL Emel , ÇETİNKAYA Şenay
Published: November 2020

The Novel Coronavirus Desease (COVID-19), which started on the 31st of December 2019, with the notification of cases of unknown pneumonia in Wuhan City, Hubei Province, China, was declared as a pandemic in order to increase the general protective measures in terms of its spreading rate and its effect on human health, and entered the group of pandemic diseases in history. COVID-19 infected 25 million people in about 220 countries during this 8-month period, and it became the 21st century's most life-threatening epidemic, being responsible for the death of 852.758 people (at the time of writing). The number of infected medical personnel in the COVID-19 outbreak is unprecedented in modern history due to the high amount of data (10%) that only includes this 4-month period. Problems such as the healthcare professionals being at the forefront of the fight against the epidemic, a lot of uncertainty at the beginning of the epidemic and the intense stress created by it, delay of measures to be taken, problems in the implementation of these measures, intense working hours, lack of information and lack of equipment are some of these risks. It is very important for healthcare professionals to protect their own health principally in order to fight this epidemic. This review has been prepared to draw attention to the risks faced by healthcare professionals in the COVID-19 outbreak, the repercussions of the infection, and to highlight the protection of healthcare professionals from infection.
Adaptation to climate change by determining grapevine cultivar differences using temperature-based phenology models
Authors: Parker Amber K. , García de Cortázar-Atauri Iñaki , Trought Michael C.T. , Destrac Agnès , Agnew Rob , Sturman Andrew , Van Leeuwen Cornelis
Published: November 2020

Grapevine phenology is advancing with increased temperatures associated with climate change. This may result in higher fruit sugar concentrations at harvest and/or earlier compressed harvests and changes in the synchrony of sugar with other fruit metabolites. One adaptation strategy that growers may use to maintain typicity of wine style is to change cultivars. This approach may enable fruit to develop under temperature conditions similar to those typically associated with that wine style. We demonstrate that Grapevine Flowering Véraison (GFV) and the Grapevine Sugar Ripeness (GSR) models can be implemented as a means of testing the suitability of alternative cultivars as an adaptation strategy to climate change.Previous viticulture temperature-based models were reviewed and compared with the GFV and GSR models. The results from the original GFV and GSR models were combined to evaluate the classification of the 20 most represented cultivars. The GFV and GSR models were tested for three new historic and contrasting datasets: 31 cultivars in the VitAdapt collection, Bordeaux; Chardonnay, Champagne; and Sauvignon blanc, Marlborough. Errors of predictions were less than a week for flowering and véraison, and within 7-10 days for the time to reach relevant target sugar concentrations for these datasets. Future GFV and GSR projections for Chardonnay resulted in an advance at a rate of one to two days per decade for flowering and véraison, and two to five days per decade for time to 170 g/L sugar concentration for RCP 4.5 and 8.5 respectively.Therefore, the GFV and GSR models are highly accurate and easy-to-use temperature-based phenological models for predicting flowering, véraison and time to target sugar concentrations when tested under new conditions. The models can be applied for characterising new cultivars, and assessing thermal time to flowering, véraison and different sugar targets. They can be used to assess cultivar performance in winegrowing areas worldwide under current or future climate conditions. The classifications therefore enable growers and researchers to compare the phenology of cultivars in a region today and to consider adaptation options: selecting later ripening cultivars or choosing alternative sites in the context of climate change.

Conclui-se que, mesmo condicionadas pelos instrumentos normativos, as chamadas públicas possibilitaram integrar novos atores como promotores e beneficiários dos serviços, constituir ações dialógicas, e fortalecer as articulações territoriais. Por outro lado, sugere-se que maiores esforços devem ser direcionados ao refinamento institucional, a fim de sintonizar esses elementos com as necessidades locais.
Max-Min Rate Fairness Optimization for In-Band Full-Duplex IoT Networks: User Grouping and Power Control
Authors: Khanh Ngo Tan Vu
Published: November 2020

The skyrocketing growth in the number of Internet of Things (IoT) devices will certainly pose a huge traffic demand for fifth-generation (5G) wireless networks and beyond. In-band full-duplex (IBFD), which is theoretically expected to double the spectral efficiency of a half-duplex (HD) wireless channel and to connect more devices, has been considered as a promising technology to accelerate the development of IoT. To exploit the full potential of IBFD, the key challenge is how to handle network interference (including self-interference, co-channel interference and multiuser interference) more effectively. In this paper, we propose a simple yet efficient user grouping method, where a base station (BS) serves strong downlink users and weak uplink users and vice versa in different frequency bands, mitigating severe network interference. We aim to maximize a minimum rate among all users subject to bandwidth and power constraints, which is formulated as a highly nonconvex optimization problem. By leveraging inner approximation framework, we develop a very efficient iterative algorithm to solve this problem, which guarantees at least a local optimal solution. Numerical results are provided to show not only the benefit of using full-duplex raido at BS, but also the advantage of the proposed user grouping method.
Reflections on erotization and childhood from the analysis of advertisements
Authors: Monteiro Solange Aparecida de Souza , Ribeiro Paulo Rennes Marçal
Published: November 2020

This paper aims to analyze advertisements and discuss child erotization in content and images of children to disseminate both products that can be used by them and the use of children in advertisements for the adult public. The advertisements make use of different technologies and are disseminated both in print and digital media. To carry out this work we rely on some studies on erotization of children's bodies, presenting elements that build the image of the adult child in the media under the bias of erotization and sensuality, their multiple readings and meanings attributed to them. We consider that these controversial discourses are the engine of early sexuality. We use the theoretical assumptions of the French line discourse analysis. Analyzing this corpus is justified because it is necessary to look at children's advertising with responsibility. Anticipating incompatible attitudes with the age group can promote the decline of childhood, because the child ceases to live a very important stage in human development and can trigger future psychological problems and present difficulties of creativity, socialization and disorders not proper to childhood. We also emphasize that the adultization process refers to the child's distance from the infantile world and early insertion into the adult world, of which they incorporate physical and psychological typologies.

Published: November 2020

One of the efforts to accelerate the achievement of corn self-sufficiency is the efficiency of farming through the use of agricultural machinery. The use of agricultural machinery at the farm level especially in planting and fertilizingis still scarcely done, while the availability of agricultural labor is decreasing recently. Innovations will be adopted by farmers based on its performance in the field which should be applicable and efficient. The study aims to determine the performance of seed planters as planting and fertilizing tool on dry land in Sigi Regency. The research method uses agro technical studies that measure theoretical work capacity (Kt), actual work capacity (Ka), as well as the efficiency of seed planter and tugal performance. The results shows that seed planter’s performance is higher than tugal. The seed planter has an average theoretical field capacity 1.92 ha/hour with an advanced speed of 6.42 km/hour and has an actual field capacity 0.625 ha/hour, whiletugal toolhas theoretical capacity 0.50 ha/hour with an average actual field capacity 0.167 ha/hour. However, the accuracy of the volume of seed and fertilizer fallfrom the seed planter have to be improved.
COPING STRATEGIES WITH MUTUAL COOPERATION AND USE OF LOCAL RESOURCES ON DISASTER BY NEPALESE RURAL PEOPLE: A CASE FROM NUWAKOT DISTRICT, NEPAL
Authors: Dhakal Dipendra , Yoshino Keiko
Published: November 2020

Nepal is vulnerable to environmental disasters such as earthquakes, landslides, floods and hurricanes. These disasters disproportionately affect rural life. Disaster risks are often approached in a purely technical and physical manner, but people’s behaviour in the face of natural hazards and disasters is influenced by various factors such as historical, economic, political and socio-cultural factors. This case uses a post-disaster resilience assessment focusing on cooperation during the recovery after a severe earthquake that hit central Nepal in 2015 which impacted rural communities. This paper analyses the people’s behaviour and its basic logic at post-earthquake recovery from a socio-cultural aspect focusing on the gaun, the basic minimal informal social unit. Special consideration was made to the ethnic heterogeneity of the communities studied. For the purpose of this study, key informants interview (KII), group discussion and transect walk were used. This study finds that gaun based local resources are traditional and primary resources for people’s daily life but the ward and VDC based resources are newly formed. Various forms of cooperation were observed regardless ethnicity at the gaun level. This study further reveals that local people’s activities towards the post-disaster recovery can be described in three periods. They are: emergent, resilient, reconstruction periods. On the basis of the study of these periods for post-disaster recovery, a very good social relationship among gaun people at emergency was realized.
Special Issue on Design and Manufacturing for Environmental Sustainability
Authors: Umeda Yasushi
Published: November 2020

This is the fifth Special Issue on Design and Manufacturing for Environmental Sustainability. The first Special Issue on this topic was issued in 2009, and the previous one was in 2018. The acceptance of sustainability has been increasing, as evidenced by the United Nations’ Sustainable Development Goals (SDGs), various carbon neutral movements, and, among others, the gradual recognition of potential impacts of the EU’s “Circular Economy,” which promotes circulation-based businesses to increase the employment and market competitiveness of the EU. This increase in acceptance has brought with it increased activity in the research area of design and manufacturing for environmental sustainability, with the result that this fifth Special Issue includes seventeen well-written papers, a significant increase over the six that appeared in the fourth.

The first paper “Potential Impacts of the European Union’s Circular Economy Policy on Japanese Manufacturers” overviews the EU’s Circular Economy and points out key enabling technologies. To approach environmental sustainability, we should promote various technologies related to ecodesign, process technologies, business strategy, and digital technology. At the same time, we must focus on life cycle design and management, an indispensable technology which synthesizes a sustainable circulation system by integrating the technologies mentioned above. Accordingly, this Special Issue covers both aspects, with the seventeen manuscripts in it organized as follows. The first three papers, authored by Y. Umeda et al., K. Halada, and M. Kojima, give overviews and discuss requirements for technological development. The next two manuscripts by K. Fujimoto et al. and Y. Kikuchi et al. discuss modeling, simulation, and assessment of circulation systems. Papers six to eight, written by W.-H. Chung et al., S. Yamada et al., and K. Yoda et al. develop life cycle design methods. The remaining manuscripts advance fundamental technologies. Manuscripts nine to eleven, by R. Yonemoto et al., T. Samukawa et al., and Y. Yaguchi et al., deal with sustainable manufacturing. Finally, six manuscripts by C. Tokoro et al., K. Tsuji et al., A. Ogawa et al., A. Yoshimura et al., T. Hiruta et al., and S. Nasu et al. are about life cycle processes; recycling technologies and product use phase such as car sharing and maintenance.

Most of the papers, revised and extended in response to the editor’s invitations, were originally presented at EcoDesign 2019: the 11th International Symposium on Environmentally Conscious Design and Inverse Manufacturing, held in Yokohama, Japan.

The editor sincerely thanks the authors and reviewers for their devoted work in making this Special Issue possible. We hope that these articles will encourage further research into design and manufacturing for environmental sustainability.

Published: November 2020

Inquiry Based Learning (IBL) is a form of active learning, often used in STEM education to promote conceptual learning and to acquire scientific investigation skills. This paper reports on a study in which teachers in Kenya, Nigeria and the Republic of Benin implemented IBL embedded in online and offline Inquiry Learning Spaces (ILS) in their classes using the Go-Lab platform (https://www.golabs.eu). After a brief description of the IBL methodology, of lab work and in particular virtual labs for STEM education, of the process of preparing teachers to use IBL in class, and of the context of this study, we highlight the methodology used, and finally report our results.

The aim of this paper is to present all relevant information regarding the very first operation of a Progressive Vortex Pump (PVP) string in a production well of a continuous steam injection stimulated field, located in the northeast part of Brazil. The string used had a configuration similar to a typical Progressive Cavity Pump (PCP), with the pump being driven around 1,100 rpm by an electric motor located at the wellhead, through a sucker rod string. The paper will address all relevant information gathered during field operation.

The procedure consisted of running a complete PVP string in a production well from a continuous steam injection stimulated field, for a period of up to six months or until a failure happened. The operation was monitored with a SCADA system acquiring relevant data, like demanded amperage and power from the electric motor and estimated torque at which the sucker rods were subjected. Flow rate tests were performed monthly, with their results enabling the comparison of the pump's performance when pumping water only and production fluid. After the failure, the string was pulled out from the well to be subjected to a thorough analysis in order to determine the root cause.

Running a sucker rod string at 1100 rpm, well beyond the 300 rpm – 400 rpm limit typically found in Progressive Cavity Pumps, showed to be very challenging. At first glance, the present system configuration, with a sucker rod string driven pump, may sound to be a cost effective approach, especially by avoiding the use of a submersible electric motor. With that in mind, the paper will also discuss potential areas to improve overall system lifetime.

Originally, a Progressive Vortex Pump was designed for automotive application, to pump gas from a car's tank to the fuel injection system. Therefore, the system as described in this paper is the very first successful attempt to apply such technology in the oil and gas E&P industry.

The aim of this paper is to present all relevant information regarding the very first operation of a Progressive Vortex Pump string in a production well of a continuous steam injection stimulated field, located in the northeast part of Brazil. The paper will address how to properly configure the variable speed drive, the rod string specification and the flow rate test results.
Surface Diagnostics and Analysis in Optimization Technologies for Sucker Rod Pump Lifted Oil and Gas Wells

Published: November 2020

Sucker rod pumping is a common artificial lift method for oil and gas wells in the United States. For decades when using this method, well analysts and production engineers looked at surface and downhole dynamometer cards to diagnose various downhole and surface equipment issues. In more recent years, advantageous rod pump diagnostic software tools have helped train well analysts and production engineers in the analysis of downhole dynamometers cards using comprehensive libraries of known behavior. Unfortunately, the same libraries do not exist for surface dynamometer cards. Without these libraries, diagnostics are based solely on information captured in the downhole dynamometer card. While most data used for analytics and diagnostics can be found in the downhole dynamometer card, a more comprehensive analysis can be done by looking at both the downhole and surface dynamometer cards.

Recently, great strides have been made to analyze data and patterns not only found in downhole dynamometer cards, but also surface dynamometer cards. Dynamometer card analysis experts agree that in some cases pump tagging and shallow friction are more visible in the surface dynamometer card than the downhole dynamometer card. Based on these expert opinions, algorithms have been developed that leverage data science tools and statistical methods to better detect both shallow friction and pump tagging problems that are visible in the surface dynamometer card well before they can be seen in the downhole dynamometer card, especially for deep wells.

These new algorithms will be additional tools to help well analysts and production engineers more quickly and effectively analyze dynamometer cards and optimize production for the sucker rod pumping system. While current downhole analytical software does provide great benefits to users, adding additional algorithms will provide a more robust and effective dynamometer card analysis.
Degraded Image Enhancement Using Dual-Domain-Adaptive Wavelet and Improved Fuzzy Transform

Published: November 2020

A novel enhancement algorithm of degraded image based on dual-domain-adaptive wavelet and improved fuzzy transform is proposed, aiming at the problem of surveillance videos degradation caused by complex lighting conditions underground. The dual-domain filtering (DDF) is used to decompose the image into low-frequency sub-image and high-frequency sub-images. The contrast limited adaptive histogram enhancement (CLAHE) is used to adjust the overall brightness and contrast of the low-frequency sub-image. Discrete wavelet transform (DWT) is used to obtain low frequency sub-band (LFS) and high frequency sub-band (HFS). The wavelet shrinkage threshold method based on Bayesian estimation is used to calculate the wavelet threshold corresponding to the HFS at different scales. A Garrate threshold function that introduces adaptive adjustment factor and enhancement coefficient is designed to adaptively de-noise and enhance the HFS coefficients corresponding to wavelet thresholds at different scales. Meanwhile, the gamma function is used to realize the correction of the LFS coefficients. The constructed PAL fuzzy enhancement operator is used to perform contrast enhancement and highlight area suppression on the reconstructed image to obtain an enhanced image. The proposed algorithm is evaluated by subjective vision and objective indicators. The experimental results show that the proposed algorithm can significantly improve the overall brightness and contrast of the original image, suppress noise of dust & spray, enhance the image details and improve the visual effect of the original image. Compared with the images enhanced by the STFE, GTFE, CLAHE, SSR, MSR, DGR, and MSWT algorithms, the comprehensive performance evaluation indicators of the images enhanced by the proposed algorithm are increased by 312.50%, 34.69%, 53.49%, 22.22%, 32.00%, 10.00%, 60.98%, 3.13%, respectively. At the same time, comprehensive performance evaluation indicator of the enhance image and the robustness is the best, which is more suitable for image enhancement in different mine environments.

Background: Reducing effectiveness of broad-spectrum cephalosporins against Enterobacteriaceae infections has been recognized. This study aimed to investigate risk factors and clinical significance of third-generation cephalosporin nonsusceptibility (3GC-NS) among the cases of monomicrobial Enterobacteriaceae bacteremia (mEB) at regional or district hospitals.Methods: The study was conducted at three hospitals at southern Taiwan between Jan. 2017 and Oct. 2019. Only the first episode of mEB from each adult (aged ≥20 years) was included. The primary outcome was in-hospital crude mortality.Results: Overall there were 499 episodes of adults with mEB included, and their mean age was 74.5 years. Female predominated, accounting for 53% of all patients. Escherichia coli (62%) and Klebsiella pneumoniae (21%) were two major causative species. The overall mortality rate was 15% (73/499), and patients infected by 3GC-NS isolates (34%, 172/499) had a higher mortality rate than those by 3GC-susceptible isolates (66%, 327/499) (21% vs. 11%, P=0.005). By the multivariate analysis, 3GC-NS was the only independent prognostic determinant (adjusted odds ratio [AOR], 1.78; P=0.04). Of note, male (AOR 2.02, P=0.001), nosocomial-acquired bacteremia (AOR 2.77, P<0.001), and usage of nasogastric tube (AOR 2.01, P=0.002) were positively associated with 3GC-NS, but P. mirabilis bacteremia (AOR 0.28, P=0.01) and age (AOR 0.98, P=0.04) negatively with 3GC-NS.Conclusion: For adults with Enterobacteriaceae bacteremia, 3GC-NS signifies a significant prognostic impact. Efforts to rapid identification of such antimicrobial resistance profiles should be incorporated into antimicrobial stewardship programs to achieve favorable outcomes.
