Published: November 2022

The purpose of the present study was to observe changes in levels of brain-derived neurotrophic factor (BDNF), vascular endothelial growth factor (VEGF), resting metabolic rate (RMR) and maximum oxygen consumption (VO2max) in the gymnast children after an anaerobic gymnastics training program. Thirty beginner gymnasts aged 8-12 years old were randomly assigned to control (n = 15) and experimental (n = 15) groups. The anaerobic gymnastics training was conducted for 8 weeks, 3 times per a week. Each session lasted 45 minutes: 10 min warm-up, 30 min core exercise, and 5 min cool down. The anthropometric and body composition of subjects were measured and growth factors were measured by using human  BDNF and VEGF PicoKine™ ELISA Kit and analysis was performed using sandwich enzyme-linked immunosorbent assay (Morland et al.) before and after the intervention, and VO2max, maximum heart rate and RMR were measured using a gas analyzer. At the baseline there were not any significant differences between both groups (p>0.05). But in the post-test, a significant difference was observed for BDNF(p=0.02) and VEGF(p=0.018) values between the two groups. Within-group there was a decrease in the value of the maximum heart rate indicator (P<0.05) and VO2max and BDNF increased significantly after an intervention (P<0.05). In conclusion, the results of the present study suggest that anaerobic gymnastic training increases the level of salivary BDNF and VEGF in children. These types of exercises may also improve cardiorespiratory fitness in children.

Over Dependency on Groundwater in India: Issues and Insights
Authors: Sinha R. S. , Chaurasia Pratik Ranjan
Published: November 2022

The present analysis shows that there is no compatibility between annual rainfall, annual recharge, annual draft, and the number of OCS blocks indicating serious discrepancies in the available information. Apart from this, different groundwater assessments from 2004 show no significant increase in annual groundwater draft, according to a report from the United Nation, groundwater abstraction continued to rise sharply in India. It is also observed that though, there is no significant change in the long-period average annual rainfall of the country, in general, the states in the northwest and central India, like Punjab, Haryana, and Uttar Pradesh are facing a remarkable downward trend in seasonal (monsoonal) and annual rainfalls both. The states of the country’s western region, like Rajasthan and Gujrat, are witnessing an upward trend in both seasonal (monsoonal) and annual rainfalls. States of southern India are not much affected. Due to declining rainfall in some of the major food grain-producing states, the balance of water distribution in the country is shifting and it may become more prominent in the years to come. India is already the largest abstractor of groundwater in the world and in the above scenario, there will be tremendous pressure on groundwater in the future. This calls for out-of-the-box solutions for groundwater restoration in India. The suggested actions which may counter the looming water crisis in the country, particularly in north-western and central Indian states, include increasing forest cover up to 20% in the next 25 years in poorly forested states, limiting area under water-guzzling greenhouse producing gas crops, starting land subsidence survey in cities, limiting groundwater abstraction and injecting water into aquifers, launching group schemes of drip and sprinkler irrigation on a large scale using existing tube-wells/wells, searching the alternative source of water by developing integrated facilities to retrieve, treat, store, and transport wastewater, transferring groundwater from groundwater surplus areas to scarce areas, enacting comprehensive central law on groundwater, improving water and agriculture resource efficiency through the Internet of Things, cloud and sensor-based network, mapping and time-bound renovation of large traditional water bodies (>1 hectare), revisiting groundwater assessment methodology and norms, quantifying static groundwater resource, developing heat tolerant and less water consuming crops and changing food habits.

Published: November 2022

Throughout the COVID-19 crisis, everyone has observed many disruptions in the pharmaceutical supply chain. Indeed, this global and complex supply chain is vulnerable, especially when it must face a sudden rise in global demand. To adapt to the increasing demand and the numerous shortages, the United States White House has suggested several recommendations (The White House, 2021). Three of them will be detailed in this report: boosting local production, building an emergency capacity, and promoting international cooperation. With more than 10,000 locations and retail stores in the United States and with the competition of large retail stores like Target and Walmart, CVS has continued to enhance its supply chain by rolling out vendor technological portals designed to facilitate its supply chain programs and models. Most of CVS’s generic products and retail merchandise are manufactured outside the United States. To ensure the sustainability and efficiency of their models, integrated planning, internal and external collaborations, and dissemination of forecasting models with suppliers help them to predict and manage demand uncertainties. CVS is digitally connected to give people more options by using their artificial intelligence platform, thereby harnessing the power of digital technology and the Omni channel sourcing to ensure that their customers are reached/served whenever, and by whatever means possible. During the COVID-19 pandemic, CVS faced three major issues related to the distribution of common drugs between patients with chronic illnesses and patients with COVID-19 pneumonia, a high volume of customer calls, and high procurement costs of medicines from suppliers due to shortages. This led CVS to implement temporary mitigation measures that set it apart from its competitors and helped serve more patients in an orderly fashion. Based on the learnings from CVS, this report presents a set of short-term solutions that can be implemented by CVS to insulate it from future shortages until the long-term solutions are implemented in collaboration with the FDA and drug suppliers.

Gold nanoparticles are very useful in various fields such as photoacoustic imaging microscopy, biotechnology, optoelectronics, and biomedicine. So the production of gold nanoparticle synthesis needs to be developed to an industrial scale. The purpose of this study is to determine the feasibility of the gold nanoparticle synthesis project using the laser ablation method on large-scale based on economic aspects. Several economic evaluation parameters are analyzed to inform the potential production of AuNP, such as GPM (Gross Profit Margin), BEP (Break-Even Point), CNPV (Cumulative Net Present Value), PBP (Payback Period), and PI (Profitability Index). The results showed that the production of AuNP nanoparticles was so prospective. Technical analysis to produce 100 g of AuNP nanoparticles per day shows the total cost incurred by the production process is 2,323,180 USD per year. PBP analysis show that investment will be profitable after more than 2.2 years. This project can compete with PBP capital market standards because of the short investment returns. To ensure the feasibility of a project, the project is estimated from ideal conditions to the worst case in production, including labor, sales, raw materials, utilities, and external conditions.

Urban sprawl is a phenomenon of the unplanned physical appearance spread in the city due to the rapid development of the city. The limited availability of land triggers its development to extend to the suburbs which causes land conversion. This phenomenon occurs due to the development of the city which continues to grow but has limited space. This study aimed to spatially examine land-use conversion and urban sprawl patterns in Sokaraja as a WPU (peri-urban area) from Purwokerto and its close distance to Purbalingga City. This study used a qualitative descriptive method to analyze land-use conversion and urban sprawl patterns using built-up area indicators including settlements and places of activity, agricultural land, and road network. The study was conducted on land use spread over 18 urban villages. Remote sensing analysis with image interpretation of the ArcGIS 10.6 software application was used to review four-time series, namely 2005, 2010, 2015, and 2019. The results of the study found that in a span of 14 years there had been a land conversion in Sokaraja subdistrict. This is evidenced by the increase of the building area which includes settlements and places of activity by 261,991 Ha (8,901%) and followed by a decrease in the area of agricultural land by 261,991 Ha (8,901%). The urban sprawl pattern found is a combination of leapfrog development and ribbon development.

Authors: Sunarjono Sri , Ngafwan Ngafwan
Published: November 2022

Many road pavements using asphalt mixtures in Indonesia are found to be not durable, especially heavy traffic roads. Even road damage often occurs early before the service life is reached. Many efforts have been made to improve the strength and durability of the mixture, but have not been effectively. For example, the use of fillers can increase the strength and durability of the mixture significantly, but its performance at low temperatures has an impact on the risk of hardening and cracking. The research objective is to propose the idea of implementing nanotechnology for palm oil waste materials to increase the durability of road pavement materials based on the research roadmap developed. The method used is through five approaches, namely: (i) review of research results on the durability of road pavement materials, (ii) review of research results on the implementation of nanotechnology in road pavement materials, (iii) research gaps, (iv) research ideas, and, (v) proposed research roadmap. A research roadmap for the implementation of nanotechnology to improve the durability of road pavement materials has been prepared. The substance of the research roadmap proposes three ideas, namely maximizing the function of nanomaterials as: (i) anti-aging agent, (ii) protecting water infiltration into the body of the asphalt mixture, and (iii) bonding agent between asphalt-aggregate.

O presente artigo intenta contemplar a presença e trajetória do fado no Brasil desde inícios do século XX, questão com a qual o acréscimo do número de imigrantes portugueses no país mantém estreita relação. Por meio da vida e atuação de artistas, empresários e intelectuais, conseguimos entender a entrada e difusão do fado no Brasil, além da insurgência do fado enquanto elemento constituidor de uma identidade nacional e fundamental na unidade entre os portugueses e seus descendentes. Conseguimos, por meio da biografia de artistas e músicos, ver a forma como o fado se adaptou ao solo brasileiro, integrando o repertório de cantores e se hibridando com ritmos e gêneros musicais brasileiros. Ademais, identificamos suas formas de difusão através dos discos, meios de comunicação de massa, teatro e, especialmente, restaurantes típicos portugueses.
