A Portraiture of Environmental Justice in Communities of Concern

Environmental justice as a movement is an urgent step towards the realization of environmental equity. There is a necessity that makes environmental justice an important solution to climate change. The origin of the necessity was the damage that environmental racism was causing, and its realization in the United States and later as an international phenomenon. Through a theoretical approach, this article examined how communities of concern are denied environmental justice as a result of the current developmental models in practice and showed why they are vulnerable to the global challenge of climate change and environmental pollution. It identified the link between human rights and the environment. It explored a viable sustainable development model for communities of concern and concluded on how they can get past the economic challenges of implementing green industries.

Predictive Control-Based NADIR-Minimizing Algorithm for Solid-State Transformer

Solid-state transformers (SSTs) are becoming an important solution to control active distribution systems. Their significant flexibility in comparison with traditional magnetic transformers is essential to ensure power quality and protection coordination at the distribution level in scenarios of large penetration of distributed energy resources such as renewables, electric vehicles and energy storage. However, the power electronic interface of SSTs decouples the nature of the inertial and frequency responses of distribution loads, deteriorating the frequency stability, especially under the integration of large-scale solar and wind power plants. Despite the virtual inertia/voltage sensitivity-based algorithms that have been proposed, the frequency sensitivity of loads and the capability of guaranteeing optimal control, considering the operating restrictions, have been overlooked. To counteract this specific issue, this work proposes a predictive control-driven approach to provide SSTs with frequency response actions by a strategy that harnesses the voltage and frequency sensibility of distribution loads and considers the limitations of voltage and frequency given by grid codes at distribution grids. In particular, the control strategy is centered in minimizing the NADIR of frequency transients. Numerical results are attained employing an empirically-validated model of the power system frequency dynamics and a dynamic model of distribution loads. Through proportional frequency control, the results of the proposed algorithm are contrasted. It is demonstrated that the NADIR improved about 0.1 Hz for 30% of SST penetration.

In vitro propagation of Vanda tricolor Lindl. var. suavis protocorm on media containing liquid organic fertilizer as a substitute for MS media

Vanda orchids have a high economic value in the flower industry, so it is necessary to have seeds available at all times. Tissue culture technology offers an important solution to produce plants in large numbers, but it is very costly in media preparation. Hence, it is necessary to have low-cost options for the application of planting media. One way of doing this is to substitute the composition of Murashige and Skoog (MS) media with alternative sources that are more affordable. Liquid organic fertilizer contains macro, micro, and good nutrients for the growth of explants. This study used explants from the protocorm of Vanda tricolor Lindl orchid. var. suavis aged three months planted on media containing liquid organic fertilizer, namely Nasa, Bio88, and Fortune. The parameters observed were the number of shoots and the number of leaves in each treatment. The data were analyzed using the Kruskal-Wallis test at the 5% level, and if there was an effect, it was continued with the Mann-Whitney test. The results showed that liquid organic fertilizer gave different responses to the Vanda tricolor Lindl. var. suavis protocorm. Liquid organic fertilizer has a significant effect on the number of shoots and number of leaves.

Hybrid Electrical System Optimization of Remote Island using HOMER

Renewable energy is an important solution in improving access to electricity, especially in isolated areas including the utilization of solar power however intermittency is becoming the main challenge that is faced in the application of Solar Power Plant (SPP). Hybrid system implementation becomes a strategy in an effort to improve system reliability based on the variation in load and intermittency of SPP. Salemo Island is one of the areas that has utilized SPP as one of the sources of electricity energy, but its operation has not been optimal as the load increases, therefore, a study was conducted to optimize the hybrid electrical system based on the current existing conditions. The results of the study showed that with the addition of SPP capacity of 200 kWp and the addition of batteries as much as 120 units, it could obtained an optimal Leveled Cost Of Energy (LCOE) value of 1,306 IDR/kWh and operating costs of 450 million with a Net Present Cost (NPC) of 8.4 billion and a capital cost of 3.2 billion. Another option is the addition of SPP 150 kWp with a lower capital cost value of 2.02 Billion, but greater than the aspect of operating cost of 883 million and LCOE of 1,897 Rp/ kWh

Case Series: Use of Coralline Hydroxyapatite Graft In Faciomaxillary Surgery

Bone grafting represents an important solution for defects in maxillofacial and orthopaedic surgeries. Ideal properties of a bone graft allow proper integration, enabling cosmetic appeal and mechanical functionality. Whilst current autograft, allograft and xenograft applications do exist and are regularly used clinically, they are associated with numerous solutions, such as availability, disease transmission and donor site morbidity. Synthetic and naturally sourced solutions can avoid these issues, whilst maintaining the ideal bone integrative properties of their autograft counterparts. This case series aims to identify the effectiveness of a natural bone graft substitute, coralline hydroxyapatite, in maxillofacial applications, and demonstrate that coralline hydroxyapatite encourages bone ingrowth for dental defects.

Factors Affecting Food Accessibility of Rural Households:A Study in Birbhum, West Bengal

In view of the goal of achieving ‘Zero Hunger’ by 2030 set in the United Nations Summit, 2015, the present study makes an attempt to identify the determinants of food accessibility of rural households in six selected villages of two blocks of the district of Birbhum, West Bengal. Food accessibility implies ability to acquire food through various means. The study is based on primary data collected from field survey in a few sample villages. The total sample size is 500. Food accessibility of the households is analysed in terms of their monthly per capita consumption expenditure (MPCE) on food. This calculated MPCE has been compared with the MPCE on food as per the minimum food basket for rural India set by the Planning Commission in 2014. The households have been classified into two groups, viz, households lying above the specified threshold of food accessibility are considered to be those having food accessibility and households below that cut off of food accessibility are taken to be those not having that accessibility. Logit regression, applied for finding out the determinants, reveals that number of years of education of the heads of the households, female literacy rate, monthly income of the households, work force participation rate positively influences food accessibility, while monthly expenses on intoxicants have a deterring effect on food accessibility of the households. The study suggests that access to sustainable employment opportunities for the poor can be the most important solution for achieving ‘Zero Hunger’.

Assessing Antimicrobial Resistance, Utilization, and Stewardship in Yemen: An Exploratory Mixed-Methods Study

Antimicrobial resistance (AMR), largely driven by irrational use of antimicrobials, is a global, multifaceted problem calling for a complete understanding of all contributory factors for effective containment. In conflict settings, war-wounds and malnutrition can combine with existing social determinants to increase demand for antibiotics, compounding irrational use. In this study, we focus on Yemen, a low-income country with active conflict for the last 5 years, and analyze the current status of awareness and stewardship efforts regarding AMR. We performed a survey of prescribers/physicians and pharmacists to describe perceptions of AMR prevalence, antibiotic use practices, and stewardship in Yemen, supported by a nonsystematic scoping literature review and a key informant interview. Participants (96%, N = 57) reported a perceived high AMR prevalence rate. Prescribers (74%, 20/27) reported pressure to prescribe broad-spectrum antibiotics. In the majority of cases (81%, 22/27), antimicrobial sensitivity tests (AST) were not performed to inform antibiotic choice. The main barrier to AST was cost. Most pharmacists (67%, 18/27) sold antibiotics without prescriptions. Amoxicillin (including amoxicillin-clavulanate) was the most-commonly prescribed (63%, 17/27) or dispensed (82%, 22/27) antibiotic. AST was rated the least important solution to AMR in Yemen. While there was awareness of a high AMR rate, stewardship is poor in Yemen. We note that barriers to the use of AST could be addressed through the deployment of reliable, affordable, quality rapid diagnostics, and AST kits. Compulsory continuing education emphasizing the use of AST to guide prescribing and patients’ awareness programs could help avoid irrational use.

Evaluation of Participant Success in Gamified Drone Training Simulator Using Brain Signals and Key Logs

The risk of accidents while operating a drone is quite high. The most important solution is training for drone pilots. Drone pilot training can be done in both physical and virtual environments, but the probability of an accident is higher for pilot trainees, so the first method is to train in a virtual environment. The purpose of this study is to develop a new system to collect data on students' educational development performance of students during the use of Gamified Drone Training Simulator and objectively analyze students' development. A multimodal recording system that can collect simulator, keystroke, and brain activity data has been developed to analyze the cognitive and physical activities of participants trained in the gamified drone simulator. It was found that as the number of trials increased, participants became accustomed to the cognitive load of visual/auditory tasks and therefore the power in the alpha and beta bands decreased. It was observed that participants' meditation and attention scores increased with the number of repetitions of the educational game. It can be concluded that the number of repetitions lowers stress and anxiety levels, increases attention, and thus enhances game performance.
