The present study was undertaken to examine the structure and performance of hetero junctions on the fill factor, short circuit current and open circuit voltage of aInGaP/GaAsdual-junction solar cell. This goal of this work was to reduce recombination in the bottom cell so that the electrons and holes produced in the top cell with the lowest recombination participate in the output current. Semiconductors with a high bandwidth from the ?? group were studied in order to obtain a high open circuit voltage.

Abstract:
Multilevel inverters have more prominent features than 2-level inverter due to various advantages like voltage quality, low EMI etc. The semi cross switched multilevel converter topology need less number of semiconductor switches compared to cascaded H-bridge multilevel inverter, and can be implemented to any number of voltage levels. The operating modes of 7-level semi cross switched multi level inverter are discussed. Three phase seven level inverter fed induction motor is implemented in MATLAB/SIMULINK.

Abstract:
The multilevel inverter is the idea of connecting such distributed DC energy sources (solar and fuel cells in addition to rectified output of wind turbines) to a power grid. Multilevel pulse width modulation (PWM) inverters have gained importance in high performance power applications without requiring high ratings on individual devices. The elementary concept of a multilevel converter to achieve higher power is to use a series of power semiconductor switches with several lower voltage DC sources to perform the power conversion by synthesizing a staircase voltage waveform.

Abstract:
Scanning Electron Microscopy/Energy Dispersive Spectroscopy (SEM/EDS) has become less useful for semiconductor samples as feature dimensions decrease. It has become increasingly difficult to get sufficient signal from small features because of the large interaction volume of the primary beam. As the interaction volume is dependent on the accelerating energy of the primary electron beam, decreasing the accelerating voltage will decrease the interaction volume. This increases the percentage of signal from the feature of interest, but also lowers the number of peaks available for interpretation,

A DC to AC inverter can be classified in different topologies; some of these topologies are three level and multilevel inverter. Both types have some advantages and disadvantages. Three level inverters can be applied for low power applications because it is cheaper and has less semiconductor losses at high switching frequencies with poor total harmonic distortion (THD). Multilevel inverters (MLI) can be applied for higher power applications with less THD. However, the MLI has more cost and conductive power losses in comparison with three level inverters.

Abstract:
The continued use of structural plastics in consumer products, industry, and transportation represents a potential source for durable, long lasting, and recyclable roadways. Costs to dispose of reinforced plastics can be similar to procuring new asphalt with mechanical performance exceeding that of the traditional road surface. This project examines improved material development times by leveraging advanced computational material models based on validated experimental data. By testing traditional asphalt and select carbon and glass reinforced composites, both new and recycled, it is possible t

Abstract:
This review is largely based on grey literature, in particular policy documents and reports by international development organizations. While there was substantial literature on approaches and principles to GBV documentation, there was less on remote service delivery such as helplines – much of this only in the wake of the COVID-19 pandemic. In addition, very little was found on actual examples of GBV documentation in developing contexts. By definition, gender featured strongly in the available literature; the particular needs of persons with disabilities were also addressed in discussions of

Abstract:
Extreme rainfall events are expected to become more frequent and more intense in the future. Because their mitigation is a challenge and their cost to human life is large, this paper studies the impact of preemptive investment against natural disasters on the future occurrence of landslides and the losses associated with it. Based on a panel of 746 Colombian municipalities with medium and high risk of landslides and an instrumental variable approach, we find that preemptive public investment can reduce the number of landslides, the number of people who die, are injured, or disappear after a la

Full text
Abstract:
Background: In an era of explosive growth in biomedical evidence, improving systematic review (SR) search processes is increasingly critical. Text-mining tools (TMTs) are a potentially powerful resource to improve and streamline search strategy development. Two types of TMTs are especially of interest to searchers: word frequency (useful for identifying most used keyword terms, e.g., PubReminer) and clustering (visualizing common themes, e.g., Carrot2). Objectives: The objectives of this study were to compare the benefits and trade-offs of searches with and without the use of TMTs for evidence

Abstract:
Key Points Seven in 10 U.S. women of reproductive age, some 44 million women, make at least one medical visit to obtain sexual and reproductive health (SRH) services each year. While the overall number of women receiving any SRH service remained relatively stable between 2006–2010 and 2015–2019, the number of women receiving preventive gynecologic care fell and the number receiving STI testing doubled. Disparities in use of SRH services persist, as Hispanic women are significantly less likely than non-Hispanic White women to receive SRH services, and uninsured women are significantly less like

Abstract:
The learning crisis in developing countries is increasingly acknowledged (World Bank, 2018). The UN’s Sustainable Development Goals (SDG) include goals and targets for universal learning and the World Bank has adopted a goal of eliminating learning poverty. We use student level PISA-D results for seven countries (Cambodia, Ecuador, Guatemala, Honduras, Paraguay, Senegal, and Zambia) to examine inequality in learning outcomes at the global, country, and student level for public school students. We examine learning inequality using five dimensions of potential social disadvantage measured in PIS
