Despite improvements over the past 20 years, high burdens of child mortality and undernutrition still coexist in Afghanistan. Global evidence indicates that complementary feeding (CF) practices predict child survival and nutritional status. Our study aims to describe CF practices in Afghanistan and to discern underlying predictors of CF by analysing data from Afghanistan's 2015 Demographic and Healthy Survey. Multilevel models were constructed comprising potential predictors at individual, household, and community levels and four CF indicators: timely introduction of solid, semi-solid, or soft foods (INTRO), minimum meal frequency (MMF), minimum dietary diversity (MDD), and minimum acceptable diet (MAD) among breastfed children. INTRO prevalence among children aged 6-8 months was 56%, whereas the prevalence of MMF, MDD, and MAD among children aged 6-23 months was 55%, 23%, and 18%, respectively. Of the seven food groups considered, four were consumed by 20% or fewer children: eggs (20%), legumes and nuts (18%), fruits and vegetables (15%), and flesh foods (14%). Increasing child age and more antenatal care visits were significantly and positively associated with greater odds of meeting all CF indicators. Lower household wealth and lower community-level access to health care services were associated with lower odds of MDD and MAD. Disparities in achieving recommended CF practices were observed by region. CF practices in Afghanistan are poor and significant socioeconomic inequities in CF are observed across the country. Our study calls for urgent policy and programme attention to improve complementary feeding practices as an intrinsic part of the national development agenda.

The current fires raging across Indonesia are emitting more carbon than the annual fossil fuel emissions of Germany or Japan, and the fires are still consuming vast tracts of rainforest and peatlands. The National Interagency Fire Center (www.nifc.gov) notes that 2015 is one worst fire years on record in the U.S., where more than 9 million acres burned -- equivalent to the combined size of Massachusetts and New Jersey. The U.S. and Indonesian fires have already displaced tens of thousands of people, and their impacts on ecosystems are still unclear. In the case of Indonesia, the burning peat is destroying much of the existing soil, with unknown implications for the type of vegetation regrowth. Such large fires result from a combination of fire management practices, increasing anthropogenic land use, and a changing climate.The expected increase in fire activity in the upcoming decades has led to a surge in research trying to understand their causes, the factors that may have influenced similar times of fire activity in the past, and the implications of such fire activity in the future. Multiple types of complementary data provide information on the impacts of current fires and the extent of past fires. The wide array of data encompasses different spatial and temporal resolutions (Figure 1) and includes fire proxy information such as charcoal and tree ring fire scars, observational records, satellite products, modern emissions data, fire models within global land cover and vegetation models, and sociodemographic data for modeling past human land use and ignition frequency. Any single data type is more powerful when combined with another source of information. Merging model and proxy data enables analyses of how fire activity modifies vegetation distribution, air and water quality, and proximity to cities; these analyses in turn support land management decisions relating to conservation and development.

Background: Evidence-based decision-making is essential to improve public health benefits and resources, especially in low- and middle-income countries (LMICs), but the mechanisms of its implementation remain less straightforward. The availability of high-quality, reliable, and sufficient data in LMICs can be challenging due to issues such as a lack of human resource capacity and weak digital infrastructure, among others. Health information systems (HISs) have been critical for aggregating and integrating health-related data from different sources to support evidence-based decision-making. Nutrition information systems (NISs), which are nutrition-focused HISs, collect and report on nutrition-related indicators to improve issues related to malnutrition and food security—and can assist in improving populations' nutritional statuses and the integration of nutrition programming into routine health services. Data visualization tools (DVTs) such as dashboards have been recommended to support evidence-based decision-making, leveraging data from HISs or NISs. The use of such DVTs to support decision-making has largely been unexplored within LMIC contexts. In Bangladesh, the Mukto dashboard was developed to display and visualize nutrition-related performance indicators at the national and subnational levels. However, despite this effort, the current use of nutrition data to guide priorities and decisions remains relatively nascent and underused. Objective: The goal of this study is to better understand how Bangladesh's NIS, including the Mukto dashboard, has been used and areas for improvement to facilitate its use for evidence-based decision-making toward ameliorating nutrition-related service delivery and the health status of communities in Bangladesh. Methods: Primary data collection was conducted through qualitative semistructured interviews with key policy-level stakeholders (n=24). Key informants were identified through purposive sampling and were asked questions about the experiences and challenges with the NIS and related nutrition dashboards. Results: Main themes such as trust, data usability, personal power, and data use for decision-making emerged from the data. Trust in both data collection and quality was lacking among many stakeholders. Poor data usability stemmed from unstandardized indicators, irregular data collection, and differences between rural and urban data. Insufficient personal power and staff training coupled with infrastructural challenges can negatively affect data at the input stage. While stakeholders understood and expressed the importance of evidence-based decision-making, ultimately, they noted that the data were not being used to their maximum potential. Conclusions: Leveraging DVTs can improve the use of data for evidence-based decision-making, but decision makers must trust that the data are believable, credible, timely, and responsive. The results support the significance of a tailored data ecosystem, which has not reached its full potential in Bangladesh. Recommendations to reach this potential include ensuring a clear intended user base and accountable stakeholders are present. Systems should also have the capacity to ensure data credibility and support ongoing personal power requirements. [ABSTRACT FROM AUTHOR]

- Abstract
Background Adolescence is the last opportunity to reverse any growth faltering accumulated from fetal life through childhood and it is considered a crucial period to optimize human development. In Bangladesh, a growing double burden of underweight and obesity in adolescents is recognized, yet limited data exists on how, when, and where to intervene. This study assesses the dynamics of growth among adolescent girls in Bangladesh, providing insight about critical junctures where faltering occurs and where immediate interventions are warranted. Methods We pooled data from Bangladesh’s Food Security and Nutrition Surveillance Project collected between 2011 and 2014 to document the age dynamics of weight and linear growth. 20,572 adolescent girls were measured for height and 19,345 for weight. We constructed growth curves for height, weight, stunting, and underweight. We also stratified growth dynamics by wealth quintile to assess socioeconomic inequities in adolescent trajectories. Results Height-for-age z-score (HAZ) in Bangladeshi girls deteriorates throughout adolescence and especially during the early years. Mean HAZ decreases by 0.20 standard deviations (sd) per year in early adolescence (10–14 years) vs 0.06 sd/year during late adolescence (15–19 years), while stunting increases by 16 percentage points (pp) vs 6.7 pp, respectively. Conversely, BMI-for-age z-score (BAZ) increases by 0.13 sd/year in early adolescence vs 0.02 sd/year in late adolescence, and underweight decreases by 12.8 pp vs 3.2 pp. Adolescent girls in all socioeconomic groups show a similar pattern of HAZ and BAZ dynamics, but the curve for the richest quintile stays above that of the poorest across all ages. Conclusions Trends and levels of stunting and underweight among adolescent girls in Bangladesh are worrisome, suggesting substantial linear growth faltering in early adolescence, with improving weight-for-age occurring only as linear growth slows and stops.

- Abstract
[Display omitted] Reconstructing hydrological variability is critical for understanding Lake Victoria's ecosystem history, the evolution of its diverse endemic fish community, the dynamics of vegetation in the catchment, and the dispersal of aquatic and terrestrial fauna in the East African Rift system during Latest Pleistocene and Holocene times. Whereas consensus exists on widespread desiccation of Lake Victoria ∼18 – 17 ka, the re-filling history (16 – 13 ka) has remained highly controversial. Here, we present data from four new sediment cores along a depth transect. We use lithostratigraphic core correlation, sediment facies, XRF data, wetland vegetation analysis (Typha pollen), and
14 C chronologies of unprecedented precision to document Latest Pleistocene lake-level variability. At our coring site in the central basin, local Typha wetlands existed >16.7 ka, alternating with periods of desiccation. Moisture increased slightly between ca. 16.7 – 14.5 ka and wetlands with permanent, shallow ponds established simultaneously in the center and the marginal, more elevated parts of the flat lake basin. After ca. 14.0 ka, lake levels increased; wetlands in the central basin were submerged and replaced by lacustrine environments and a >50 m deep lake established ca. 13.5 ka, likely with intermittent overflow most of the time. The lake reached modern or even above-modern levels around 10.8 ka. This lake-level history is consistent with regional terrestrial paleoenvironmental reconstructions, notably the expansion of Afromontane and rainforest. Our data suggest a complex picture of paleoclimatic conditions in Eastern Africa and teleconnections to the North-Atlantic and Indian Ocean domains. [ABSTRACT FROM AUTHOR]- Published

Radiometric dating methods are essential for developing geochronologies to study Late Quaternary environmental change and
210 Pb dating is commonly used to produce age-depth models from recent (within 150 years) sediments and other geoarchives. The past two centuries are marked by rapid environmental socio-ecological changes frequently attributed to anthropogenic land-use activities, modified biogeochemical cycles, and climate change. Consequently, historical reconstructions over this recent time interval have high societal value because analyses of these datasets provide understanding of the consequences of environmental modifications, critical ecosystem thresholds, and to define desirable ranges of variation for management, restoration, and conservation. For this information to be used more broadly, for example to support land management decisions or to contribute data to regional analyses of ecosystem change, authors must report all of the useful age-depth model information. However, at present there are no guidelines for researchers on what information should be reported to ensure210 Pb data are fully disclosed, reproducible, and reusable; leading to a plethora of reporting styles, including inadequate reporting that reduces potential reusability and shortening the data lifecycle. For example, 64% of the publications in a literature review of210 Pb dated geoarchives did not include any presentation of age uncertainty estimates in modeled calendar ages used in age-depth models. Insufficient reporting of methods and results used in210 Pb dating geoarchives severely hampers reproducibility and data reusability, especially in analyses that make use of databased palaeoenvironmental data. Reproducibility of data is fundamental to further analyses of the number of palaeoenvironmental data and the spatial coverage of published geoarchives sites. We suggest, and justify, a set of minimum reporting guidelines for metadata and data reporting for210 Pb dates, including an IEDA (Interdisciplinary Earth Data Alliance), LiPD (Linked Paleo Data) and generic format data presentation templates, to contribute to improvements in data archiving standards and to facilitate the data requirements of researchers analyzing datasets of several palaeoenvironmental study sites. We analyse practices of methods, results and first order interpretation of210 Pb data and make recommendations to authors on effective data reporting and archiving to maximize the value of datasets. We provide empirical evidence from publications and practitioners to support our suggested reporting guidelines. These guidelines increase the scientific value of210 Pb by expanding its relevance in the data lifecycle. Improving quality and fidelity of environmental datasets broadens interdisciplinary use, lengthens the potential lifecycle of data products, and achieves requirements applicable for evidenced-based policy support.

- Abstract
Regions within the discontinuous permafrost zone of the southern Northwest Territories (Canada) are experiencing accelerated thaw of permafrost as a result of recent warming. We used remotely-sensed imagery (1947-2012) to track changes in the extent of peat plateau collapse around two study lakes: KAK-1 and TAH-7. Subfossil diatoms were analyzed from sediment cores to reconstruct limnological changes over the past ~300 years and assess whether peatland subsidence affected lake ecology. Extensive peat plateau collapse was evident in catchments between 1970 and present day. In TAH-7, diatom assemblages indicated a substantial increase in coloured dissolved organic carbon coincident with the time of peat collapse, suggesting that permafrost thaw has resulted in increased transport of terrestrial organic matter to the lake. At KAK-1, while also tracking changes linked to climate warming, no changes in diatom assemblages could be linked to peat plateau collapse. Using our combined approaches, we conclude that collapsing peat plateaus may significantly alter aquatic ecosystems, but the impacts of permafrost thaw on aquatic ecosystems in the sporadic discontinuous permafrost zone are complex.

- Abstract
This paper presents some analytical studies on the performance of grid connected solar photovoltaic system with different parameters in Rajasthan. The various factors that are considered for performance evaluation are: solar irradiation, ambience, tilt angle, orientation and shading. Rajasthan is rich in solar energy with varying ambience. Thus, due to change in climatic condition the PV system performance varies from place to place to a considerable extent. This influences the energy yield as well as economics of such system. In this paper a performance evaluation have been carried out for a 5 MWp crystalline silicon solar photovoltaic power plant in Rajasthan. As a part of the plant design, considerations have been taken in account on aesthetic, safety and cost aspects. The optimised annual energy yield of the 5 MWp is in the order of 8 GWh at a tilt angle of 22̊, average ambient temperature of 26 ̊Cand relative humidity (RH) of 60%. The minimum yield observed was about 7 GWhat 28̊ tilt angle, average ambient temperature of 20 ̊C and RH of 75%. These studies justified on the implementation of photovoltaic system in urban areas of developing countries where peak load demand is very high. [ABSTRACT FROM AUTHOR]

22. Transient and Harmonic Overvoltages Related to Transformer and Transmission Line Interaction During Black Start Energization

Cho, Sung D., Mork, Bruce A., and Mustaphi, Kalyan K.
- Abstract
Restoration of the power grid following a blackout is a subject of major concern for all power utilities. Such a black start typically begins by starting small gas turbine or hydro generators and using them to backfeed the high-voltage grid, energizing one piece of the system at a time. However, the energization of high-voltage transmission lines and large transformers is a challenge, since this can result in a combination of transient and sustained harmonic resonant overvoltages which may cause damage to equipment and/or lead to surge arrester failure. This paper addresses the transient and harmonic overvoltages occurring during black start procedures, discusses the development of Electromagnetic Transient Program (EMTP) models, and presents simulation results. The results of EMTP simulation using more complex models compare more favorably to the event records than the results using simpler models. Based on comparisons with measurements, modeling requirements and some guidelines necessary for obtaining accurate results are provided.

- Abstract
Background and Objectives: Wasting among under-five years old (U-5) children is a significant global public-health-nutrition burden. To effectively address this problem in Bangladesh, knowing its prevalence, caus-es and associated-factors are essential. This review aimed to identify evidences available in the existing-accessible literature/documents that describe the individual, socioeconomic, demographic, and contextual risk-factors associated with wasting among U-5 children in Bangladesh., Methods and Study Design: Electronic-databases included were MEDLINE, EMBASE, CINAHL, WoS, and Cochrane-Library written in English and published until 29 February 2024., Results: The search from the five databases yielded 167 publications. Of these, 50 papers/articles were duplicates and 108 were irrelevant, and nine have met the inclusion criteria. Additionally, 22 articles/documents were identified from other sources. Finally, a total of 31 articles/documents have been included in this review. The odds of childhood wasting observed were high for smaller birth-size, higher birth-order, male child, 12-24 months age-group, improper breastfeeding- and complementary-feeding practices, not-receiving DPT1 and/or measles vaccine, ≥1 sibling(s), maternal-undernutrition, less food-consumption during pregnancy, lack of maternal-education, lack of hand-washing practices by the mother/caregiver, paternal tobacco use, lower socioeconomic-status, food-insecurity, lack of access to hygienic-latrine and/or improved-water, Monsoon season (May-August), flood exposure, living es-pecially in Barishal, Rajshahi Chittagong and Rangpur-division and/or Eastern part of Bangladesh, and urban-slum., Conclusions: The risk/associated factors of wasting among U-5 children in Bangladesh were found at various multilevel. Rarely caused by any one factor alone, wasting in U-5 children results from an interplay between pregnant-mother's health and nutrition, child-caring practices, diets, poverty, and disease, which vary by context., Competing Interests: All the author(s) declared no potential conflicts of interest with respect to the review, authorship, and/or publication of this article

- Abstract
Introduction: There is a paucity of data on community perception and utilization of services for wasted children in Forcibly Displaced Myanmar Nationals (FDMN) and their nearest host communities., Methods: We conducted a qualitative study to explore community perceptions and understand the utilization of services for severely wasted children among the FDMN and their nearest host communities in Teknaf, Cox's Bazar. We carried out 13 focus group discussions and 17 in-depth interviews with the caregivers of the children of 6-59 months, and 8 key informant interviews., Results: Caregivers' perceived causes of severe wasting of their children included caregivers' inattention, unhygienic practices, and inappropriate feeding practices. However, the context and settings of the FDMN camps shaped perceptions of the FDMN communities. Caregivers in both the FDMN and host communities sought care from healthcare providers for their children with severe acute malnutrition (SAM) when they were noticed and encouraged by their neighbors or community outreach workers, and when their SAM children suffered from diseases such as diarrhea and fever. Some caregivers perceived ready-to-use therapeutic food (RUTF) as a food to be shared and so they fed it to their non-SAM children., Discussion: Caregivers of the children having SAM with complications, in the FDMN and host communities, were reluctant to stay in stabilization centers or complex respectively, due to their households' chores and husbands' unwillingness to grant them to stay. The findings of this study are expected to be used to design interventions using locally produced RUTF for the management of SAM children in the FDMN, as well as to inform the health sector working on SAM child management in the host communities., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be constructed as a potential conflict of interest., (Copyright © 2024 Rahman, Naila, Islam, Mahfuz, Alam, Karmakar, Ferdous, Siddique, Mustaphi and Ahmed.)

- Abstract
Effective coverage of antenatal iron and folic acid (IFA) supplementation is important to prevent adverse maternal and newborn health outcomes. We interviewed 2572 women from two rural districts in Bangladesh who had a live birth in the preceding six months. We analysed the number of IFA tablets received and consumed during pregnancy and examined the factors influencing IFA consumption by multiple linear regression and user adherence-adjusted effective coverage of IFA (consuming ≥180 IFA tablets) by Poisson regression. Overall, about 80% of women consumed IFA supplements in any quantity. About 76% of women received antenatal care at least once, only 8% received ≥180 IFA tablets, and 6% had user adherence-adjusted coverage of antenatal IFA supplementation. Multivariable analysis showed a linear relationship between the number of antenatal care (ANC) visits and the number of IFA supplements consumed, which was modified by the timing of the first ANC visit. Women's education, free IFA, and advice on IFA were also associated with higher IFA consumption. Interventions targeting at least eight ANC contacts, starting early in pregnancy, providing advice on the importance of IFA, and providing IFA supplements in higher quantity at ANC contacts are likely to increase effective coverage of antenatal IFA supplementation.

- Abstract
Despite improvements over the past 20 years, high burdens of child mortality and undernutrition still coexist in Afghanistan. Global evidence indicates that complementary feeding (CF) practices predict child survival and nutritional status. Our study aims to describe CF practices in Afghanistan and to discern underlying predictors of CF by analysing data from Afghanistan's 2015 Demographic and Healthy Survey. Multilevel models were constructed comprising potential predictors at individual, household, and community levels and four CF indicators: timely introduction of solid, semi-solid, or soft foods (INTRO), minimum meal frequency (MMF), minimum dietary diversity (MDD), and minimum acceptable diet (MAD) among breastfed children. INTRO prevalence among children aged 6-8 months was 56%, whereas the prevalence of MMF, MDD, and MAD among children aged 6-23 months was 55%, 23%, and 18%, respectively. Of the seven food groups considered, four were consumed by 20% or fewer children: eggs (20%), legumes and nuts (18%), fruits and vegetables (15%), and flesh foods (14%). Increasing child age and more antenatal care visits were significantly and positively associated with greater odds of meeting all CF indicators. Lower household wealth and lower community-level access to health care services were associated with lower odds of MDD and MAD. Disparities in achieving recommended CF practices were observed by region. CF practices in Afghanistan are poor and significant socioeconomic inequities in CF are observed across the country. Our study calls for urgent policy and programme attention to improve complementary feeding practices as an intrinsic part of the national development agenda., (© 2018 The Authors.

- Abstract
There are 11.1 million children in the age group 0-6 years in West Bengal. Of these, every second child under 3 years of age is underweight, more than four out of ten are stunted, and one out of eight are wasted. The Integrated Child Development Services (ICDS) programme in West Bengal has 355 operational projects covering 53,064 operational anganwadi centers reaching out to more than four million beneficiaries--approximately half of whom are children in the age group 0-3 years. The Department of Women and Child Development (DWCD) is trying to identify and replicate innovative, community-based, sustainable approaches. One such innovative initiative has been the "Keno Parbo Na" project based on the Positive Deviance (PD) approach which aims to reduce and prevent malnutrition among children under 3 years of age by focusing on local solutions and resources, local behaviors and practices. Behavior change is emphasized through participatory learning and community mobilization. The pilot phase of the project has been completed in two districts [Four blocks (2 in each District) and 32 villages/AWCs (8 in each block)] of West Bengal (Murshidabad and South 24 Parganas). The analysis of the project activities so far reveals that the issue of malnutrition and its prevention is now visible in the villages covered. Acceptance of desirable behavioral practices is observed within the community. A steady reduction in the moderate and severe level of malnutrition was noted across four districts. A general preponderance of girl children was noted at the entry stage indicating higher levels of severe and moderate malnutrition among girl children to begin with but also suggesting PD as an important strategy in reducing the gender gap in malnutrition. The boys gain in terms of nutritional status faster than the girls so in the intermediate phase malnourished girls are more in number. However, by the sixth / ninth round, as the malnutrition levels decline substantially, the gender gap tends to close.
