Electrical power systems are accessible in renewable energy systems, and hybrid battery systems or energy storage systems (ESS) are capable of delivering uninterruptible power to the demand even if faults occur. Additionally, the energy storage device increases system dynamics during power fluctuations. A photovoltaic (PV) battery hybrid system with an ESS link is considered, and an impact leveling management system is planned to transfer the ability to load as well as the battery. Electricity generation is vital, and also the method is fairly complicated. The goal of lowering production prices, maintaining instrumentation, and its fuels, all play necessary roles within the method. As a result, producers should import fuel to satisfy the electrical demand, the assembly value rises. We are considering using renewable energy sources to avert a harmful economic imbalance. We tend to introduce a replacement system to complete the load of alternative energy. To boost inertia and improve frequency responsiveness, load side inverters linking PV to grid and energy storage systems are used on a utility-scale (ESS). Furthermore, with growing PV penetration, independent development of PV and ESS linking to the load and the battery is one of the alternatives for steady operation of the standalone system. The associate integrated the idea for PV and ESS integration to AC load and ESS and it is used for automotive applications.

Nanomaterials play a vital role in healthcare, electronics, manufacturing industries, biotechnology, and security systems. One such material is graphene and its oxides are specifically used for recycling industrial waste water. Graphene, a single layer in honeycomb cross section, provides excellent attention because of its significant optical, mechanical, and physical properties. GO was utilized to decrease the acidic or essential centralization of the mechanical wastewater into reusable water for the modern reason utilizing graphene channels. In this paper, sample solution (waste water) is taken from paper industry. Graphene channels can be created from the pencil graphite. Graphene has the high goals of separating capacity, and graphene is considered as “a definitive RO film” in light of its stronger, thinner, and more chemically safe nature than the polymer layers. Graphene oxide layers are likewise to be used in the desalination plant in place of the RO membrane.

Abstract An unseasonal development of Equatorial Plasma Bubble (EPB)/Equatorial Spread-F (ESF) activity in a wide longitudinal sector over India and Southeast Asia during the post-sunset hours of 28 July 2014 has been investigated in detail using the multiple independent observations in this paper and a companion paper by (Prog Earth Planet Sci 5:10, 2018). This post-sunset ESF/EPB event was preceded by a substantial elevation of the equatorial F-layer due to strong pre-reversal enhancement (PRE) during the season which is climatologically unfavorable for strong PRE and post-sunset EPBs. In this paper, it is found that a strong equatorward meridional neutral wind at off-equatorial E-region and enhanced longitudinal gradient of equatorial electrojet appear to be the responsible candidates for the enhanced PRE and EPB development on 28 July 2014. These changes in the local wind system and PRE are found to have an apparent connection with the planetary wave forces of lower atmospheric origin. Both the post-sunset height rise (PSSR) and lower thermospheric meridional neutral wind consistently exhibit quasi-2-day planetary wave-like oscillations during 20–31 July 2014 with maximum amplitudes on 28 July 2014. This study emphasizes the role of planetary wave forces from the lower atmosphere that can alter the local neutral wind system and E-region conductivities that may lead to the development of strong PRE and EPB activity which were otherwise climatologically unfavorable for post-sunset EPB/ESF development.

The title compound, C18H20N2O, crystallizes with two molecules in the asymmetric unit. The seven-membered ring in both molecules adopts a distorted chair conformation. The dihedral angles between the phenyl rings are 43.2 (1) and 54.7 (1)° in the two molecules. The crystal packing features N—H...O and weak N—H...π and C—H...π interactions.

Background: Unhealthy food consumption and physical inactivity in adolescents play a key role in the development of non-communicable diseases (NCDs). Objectives: The study was planned to capture the reasons and solutions for unhealthy food consumption and physical inactivity among school-going adolescents. Methods: A school-based sequential mixed-methods study was conducted in Puducherry for six months. In Phase I, a survey (QUAN) was carried out among 405 representative students from 9th to 12th standards to identify the reasons for unhealthy behaviors. Then, Phase II compromised two focus group discussions (FGDs) (QUAL) with 20 purposively selected school staff, parents, and healthcare professionals to explore the solutions for unhealthy behaviors. In Phase III, the key action points were ranked (QUAL) by 60 teachers. Quantitative data was analyzed in Epi_Info 7.1.5.0 software (Centers for Disease Control and Prevention; Atlanta, Georgia, US). Thematic content analysis was done for the qualitative data in Atlas.ti.9 software (Scientific Software Development GmbH, Berlin). Further, mean rank and Kendall's concordance coefficient (W) were calculated for the ranked data in SPSS 24 software (SPSS Inc; Chicago, Illinois, USA). Results: About 70.1% of students had unhealthy food consumption and 61% of students lacked physical activity. Notably, 59.9% of males preferred unhealthy foods, and 65.2% of females were physically inactive. The leading reasons for unhealthy eating habits were taste (78.9%), increased online food delivery (75.7%), and attractive advertisements (74.3%). Whereas, the prime reasons for sedentary behaviors were increased study load (81.8%), high-density traffic (74.9%), and insufficient recreational facilities (71.7%). Conclusion: The prioritized feasible action points would help in the development of context-specific behavior change communication strategies for future health promotion interventions in resource-poor settings.

Background: Adrenal gland has an outer cortex and inner medulla that vary structurally, functionally, and embryologically. The developing gland plays a major role in concordance development of various viscera of the fetus and in parturition. The fetal adrenal gland shows histological changes not only in the fetal cortex but also in capsule, permanent cortex, and medulla. The current study aims to look at the changes in the microstructure of the fetal adrenal glands at various gestational ages. Methodology: Forty adrenal specimens from dead fetuses of gestational age from 14 to 36 weeks were collected and processed for routine hematoxyline and eosin staining and studied under light microscope. The samples were grouped into I, II, and III based on their gestational age. The microscopic changes occurring in different gestational ages were studied and photographed. Results: The cortex become well defined by 18 weeks and increase in thickness till term. Blood vessels appear in the capsule as early as 15 weeks. The fetal cortex increases in thickness with increase in gestational age. Lymphocytic infiltrations were consistently noted in the permanent cortex. The neuroblastic nodules were noted in the medulla from 14 weeks and regressed with advancing gestational age. Conclusion: Increase in the size of the fetal adrenal gland is mainly due to the increase in the fetal cortex. The neuroblastic nodules were seen until 32 weeks of gestation. The lymphocytic infiltration in the fetal cortex opens a new avenue of research to study their role in mediating the cortical secretions in fetus.
