Given the possibility of waterborne diseases caused by inappropriate rainwater harvesting systems, a survey was conducted in Uganda to assess existing knowledge of both physical and non-physical measures that safeguard harvested rainwater. Households who had received rainwater tanks were assessed on issues related to harvested rainwater quality. The study shows that 84% of respondents were awar...

We investigate the 21-cm emission from the epoch between reionization zr and Gunn-Peterson transparency zgp. According to the lognormal model of the thermal history around reionization, hydrogen clouds in zr > z > zgp are hot, and a predominant part of baryonic gas is ionized, but still opaque to Lyα photons. Therefore, 21-cm emission is a distinctive characteristic of this epoch. We show that ...

Environmental contamination of vegetables and fruits with intestinal protozoan trophozoites, cysts oocysts is a means transmitting parasitic agents public health importance. The purpose this systematic review meta-analysis was to determine the global prevalence parasite in fruits. Several databases (Web Science, PubMed, Scopus, ProQuest Google Scholar) were searched for literature published up ...

Accidental ingestion of infective stages helminths through consumption contaminated vegetables and fruits causes a wide range food-borne diseases in humans. This systematic review meta-analysis evaluated the global incidence helminthic contamination vegetables, cucurbits fruits. Several databases (Science Direct, Web Science, PubMed, Scopus, Google Scholar) were searched for literature publishe...

Verocytotoxin-producing E. coli (VTEC) are important agents of diarrhoeal disease in humans globally. As a noted waterborne disease, emphasis has been given to the study VTEC surface waters, readily susceptible microbial contamination. Conversely, status potable groundwater sources, generally regarded as “safe” drinking-water supply remains largely understudied. such, this investigation present...

Parasites are commonly associated with vegetable or fruit borne outbreaks of gastroenteritis. Among all pathogenic intestinal parasites, helminthes cause the most number of parasitic infections in humans and animals, especially in developing countries. We conducted a study to determine the extent of parasitic contamination of raw vegetables sold in some markets of Casablanca (Morocco) .Vegetabl...

Aspergillus species are able to produce a range of mycotoxins, including e.g. aflatoxins, ochratoxins, fumonisins and patulin. Aflatoxins are mainly produced by members of Aspergillus section Flavi, and they contaminate various agricultural products in several parts of the world. Several recent reports have indicated that aflatoxin-producing fungi and consequently aflatoxin contamination occur ...

The wettability of solid surfaces is of fundamental scientific interest and related to many diverse chemical and physical phenomena at the heart of practical technologies. In particular, the hydrophilicity of the photocatalytically active metal-oxide TiO2 has attracted considerable attention for many applications. However, the intrinsic hydrophilicity of Ti-oxide surfaces is not fully understoo...
