Using microencapsulation technology and the natural antimicrobial properties of aloe-emodin, microcapsules were prepared by in situ polymerization using urea-formaldehyde resin as wall material aloe-emodin core material. The mixed into waterborne coatings to improve ability paint films against bacteria for better protection substrates. purpose this study was optimize preparation process antibac...

The objective of this study was to examine the effects of chronically elevated dietary Ca2+ (as CaCO3), alone and in combination with elevated dietary Cd, on survival, growth, and Cd and Ca2+ accumulation in several internal compartments in juvenile rainbow trout (Oncorhynchus mykiss). In addition, effects on short-term branchial uptake and internal distribution of newly accumulated waterborne ...

The leakage of surfactant from waterborne coatings is a matter concern. Therefore, there strong interest in developing surfactant-free polymer dispersion as binders for coatings. This will accelerate the substitution solventborne by more environmentally friendly latexes. However, performance coating depends on interaction latex with pigments and fillers this controlled composition surface parti...

As an essential pigment particle in white water-based coatings, light calcium carbonate (CaCO3) is difficult to disperse systems. The hard-to-disperse particles agglomerate, causing the viscosity of coating rise, which turn affects quality coating. Therefore, order obtain efficient dispersion, hyperdispersant SSS–MPEGA–DMAEA (SMD) has been prepared this study using sodium styrene sulfonate (SSS...

With the development of economy and science technology, people put forward higher standards for performance surface coating wood products, which requires us to carry out innovative research on coating. In this work, a kind microcapsule was prepared with melamine-formaldehyde resin/rice husk powder as wall material epoxy resin core material. The microcapsules were added waterborne acrylic accord...

This is the first of a series of review articles in a Special Issue publication on waterborne zoonotic parasites. A brief historical overview of the occurrence and importance of waterborne parasites, dating from early civilization is presented. The article considers the diversity of parasites including protozoa, nematodes, cestodes and trematodes and the related zoonotic organism microsporidia....

Epidemic waterborne risks are discussed in this paper. Although the true incidence of waterborne illness is not reflected in the currently reported outbreak statistics, outbreak surveillance has provided information about the important waterborne pathogens, relative degrees of risk associated with water sources and treatment processes, and adequacy of regulations. Pathogens and water system def...

Waterborne disease statistics only begin to estimate the global burden of infectious diseases from contaminated drinking water. Diarrheal disease is dramatically underreported and etiologies seldom diagnosed. This review examines available data on waterborne disease incidence both in the United States and globally together with its limitations. The waterborne route of transmission is examined f...
