Abstract:
Abstract One major risk factor common to individuals in schistosomiasis endemic areas is water contact patterns. Effort to determine the dynamics in water contact patterns in different regions needs utmost attention in order to suggest a better control strategy for schistosome infection. Quantitative observations on human water contact activities were recorded in Yewa North Local Government Area of Ogun State for a period of two years. Frequency and duration of observed water contact activities were recorded. Males had the highest water contact during the rainy season with 51.1% compared to fe

Variations in the amount of water contact made by individuals and in the amount of water contact made at different sites may have significant impacts on patterns of human schistosome infection. Previous studies have reported variations in the rate of water contact and differences in the sites used between age/sex classes, but there is limited information on variations in individual water contact behaviour. In this paper we report and analyse observations of essentially all water contacts made over a two week period by all individuals in a rural community in eastern Zimbabwe. The mean rate of w

Human water contact patterns were studied in two resettlement communities at the Oyan Reservoir in south-west Nigeria in all four seasons in 1991 and 1992.

Both communities were highly endemic for urinary schistosomiasis. However, knowledge regarding schistosomiasis transmission was very limited and the infection was, in spite of a very high frequency of blood in the urine, not considered a major public health problem.

Several practical conclusions emerge: concentration of contacts at a single site should be avoided; the impact of control targeted at certain sites cannot

The drivers and patterns of zoonotic virus emergence in the human population are poorly understood.

Here, we show that human specialization and subsequent spread of A. aegypti out of Africa were accompanied by an increase in its intrinsic ability to acquire and transmit the emerging human pathogen Zika virus.

Abstract:
Extended Spectrum Beta Lactamase (ESBL)-producing Escherichia coli (E. coli) infections are a global health challenge resulting from human contact with infected animals and contaminated farm environments. This study aims to identify antimicrobial resistance patterns of ESBL-producing E. coli isolated from dairy farms in the Sleman District of Yogyakarta Province, Indonesia. Ninety-three dairy farms with a history of antibiotic use in the previous 6 months were identified. Samples were collected from 6 different sources (feces, milk, wastewater, animal drinking water, feed and rinses of workers

Abstract:
Atmospheric water generator (AWG) technologies are considered a potential new source of freshwater. Thermoelectric (TEC) dehumidifiers are one of this technology where it uses the Peltier effect to create a heat flux at the junction of two different materials. This device is well known for its thermoelectric cooling application, from as small as portable beverage coolers to as big as submarines. The problems of using this device are ice buildup and relatively low efficiency. If the surface of the material can be engineered in a way that the dropwise condensation, as well as precipitation from

AbstractThis paper is devoted to the use of the principles of green chemistry in the search for technologies to reduce the chemical footprints of areas. The chemical footprint for mercury and its compounds was taken as an example to study. These chemicals belong to priority pollutants and their ever-increasing amounts in the environment have caused concern around the world, which is reflected in the adoption of the Minamata Convention. The Minamata Convention aims to protect human health and the environment from anthropogenic releases of mercury and mercury compounds. This Convention is an imp

The choroid plexus (CP) is a structure in the brain ventricles that produces the main part of the cerebrospinal fluid (CSF). It is covered with specialized cells which show epithelial characteristics and are the site of the blood–CSF barrier. These cells form a contiguous cell sheet with ventricle-lining ependymal cells which are known to express aquaporin-4 (AQP4). In contrast, CP epithelial cells express aquaporin-1 (AQP1) apically. We investigated the expression patterns of aquaporins in the CP-ependyma transition from human body donors using immunofluorescence and electron microscopy. Epen

Contact-less liquid identification via wireless sensing has diverse potential applications in our daily life, such as identifying alcohol content in liquids, distinguishing spoiled and fresh milk, and even detecting water contamination. Recent works have verified the feasibility of utilizing mmWave radar to perform coarse-grained material identification, e.g., discriminating liquid and carpet. However, they do not fully exploit the sensing limits of mmWave in terms of fine-grained material classification. In this paper, we propose FG-LiquID, an accurate and robust system for fine-grained liqui

Microbial communities associated with freshwater aquatic habitats and resident species are both critical to and indicative of ecosystem status and organismal health. External surfaces of turtle shells readily accumulate microbial growth and could carry representation of habitat-wide microbial diversity, since they are in regular contact with multiple elements of freshwater environments. Yet, microbial diversity residing on freshwater turtle shells is poorly understood. We applied 16S and 18S metabarcoding to characterize microbiota associated with external shell surfaces of 20 red-eared slider

Abstract:
A particle mechanical constraint (PMC) is a soft vinyl tube containing Styrofoam beads. It can be freely compressed, elongated, bent, twisted, or otherwise manipulated in all degrees of freedom. Evacuation of the air inside the tube makes the PMC rigid so that it maintains whatever shape it has been given. The stiffness of the PMC is proportional to the reduction in internal pressure below atmospheric pressure. Viscosity is also controlled virtually by changing the inside air pressure in proportion to the speed of transformation of the PMC. We used a PMC to develop a wearable force display tha
