This paper is based on a study, which aim is to provide an overview of the current MSW management in the main cities in Somaliland and Puntland and to identify strategies to improve the present situation. In particular, this article illustrates assessments concerning waste collection and technical solutions identified for its improvement, whereas waste treatment and disposal phases will be discussed in a further paper. The survey, which has been carried out in close collaboration with local administrators and technicians, has shown that MSW management is very lacking and needs both structural and operational actions. Waste collection in the surveyed cities covers 65% of population at its best, whereas it is substantially absent in Gardo and Sheik. The extension of waste collection service to the entire population of each city would need investment costs varying between 17,500 USD for Sheik and 200,000 USD for Galkayo, whereas total operational costs would vary between 1.17 USD/ inh/y in Boroma and 5.73 USD/inh/y in Garowe. Anyway, technical interventions are necessary to provide a larger number of citizens with a regular waste collection service and they should be preceded and accompanied by public awareness campaigns on environmental protection and capacity building services addressed to local administrators and technicians.

In this review paper, we provide a comprehensive overview of approaches for collecting time-activity pattern (TAP) data from individuals, a crucial component in understanding human behavior and its implications across various fields such as urban planning, environmental science, and, particularly, public health in relation to air pollution exposures.Furthermore, our paper introduces and critically evaluates several emerging methods for TAP data collection. These novel approaches, including but not limited to Google Location History, iPhone Significant Locations, and crowdsourced smartphone location data, offer unprecedented granularity in tracking human activities.

Naturally occurring bedded salt deposits are considered robust for the permanent disposal of heat-generating nuclear waste due to their unique physical and geological properties. The Brine Availability Test in Salt (BATS) is a US-DOE Office of Nuclear Energy funded project that uses heated borehole experiments underground (∼655 meters depth) at the Waste Isolation Pilot Plant (WIPP) in the bedded salt deposits of the Salado Formation to investigate the capacity for safe disposal of high-level, heat generating nuclear waste in salt. Uncertainties associated with brine mobility near heat-generating waste motivates the need to characterize the processes and sources of brine in salt deposits.

Introduction: Malnutrition contributes to approximately 45% of deaths among under 5 years children in low and middle-income countries. Poor maternal knowledge and failure to comply with recommended Infant and Young Child Feeding (IYCF) practices are known risk factors for malnutrition but there are inconsistencies in the literature. Therefore, this cross-sectional study of 100 mother-child pairs in district Gujranwala aimed to assess maternal nutritional literacy (MNL) and maternal feeding practices (MFP) and their ultimate impacts on child growth.

Objective: To investigate the fluctuations in the population density of and changes in the population density of in different geographical areas and different breeding habitats in Guangdong Province from 2018 to 2023, so as to provide insights into prevention and control of mosquito-borne infectious diseases in the province.
Methods: surveillance sites were assigned in 1 609 townships (streets) from 121 districts (counties) of 21 cities in Guangdong Province during the period between March and November from 2018 to 2023. The surveillance of the population density of was performed once a month in each surveillance site, and once a month in specific settings in cities where dengue were highly prevalent in Guangdong Province from December to February of the next year during the period from 2018 through 2023.

Background: There is limited evidence on prevalence and risk factors for hepatitis C virus (HCV) infection among waste handlers in Sidama region, Ethiopia; however, this knowledge is necessary for effective prevention of HCV infection in the region.
Methods: A cross-sectional study was conducted among randomly selected waste collectors from October 2021 to 30 July 2022 in different public hospitals of Sidama region of Ethiopia. Serum samples were collected from participants and screened for anti-HCV using rapid immunochromatography assay.
