Species of tapeworms belonging to the family Taenidae are among the most important helminth parasites of man and domestic animals. Taeniasis and cysticercosis are serious problems of public health and economy in developing countries. The ultimate control of these diseases depends on the development of effective prophylactic vaccines. Although vaccines against bacterial and viral infections are ...

A novel fiber-optic electrochemiluninescence sensor has been developed. It can be conveniently applied by placing into the sample solution in a manner similar to a conventional ion selective electrode, without requiring liquid luminous reagent and a flowing system. The sensor is consisted of an independent probe and a case for exclusion the ambient light, allowing the sample solution to pass th...

To show the impact of sensor behaviour on the control result, four strategies for aeration control are tested using different sensor characteristics. It is demonstrated, on the one hand, how an increasing response time will limit the achievable control quality and, on the other hand, how a given sensor characteristic can be taken into account for the controller design. The presented tests show ...

in this paper, the photochemical degradation of azure-b by cu2+/s2o82− process has beenpresented. cu2+ as photocatalyst and s2o82− ion as photooxidant used in this process. atextremely low concentrations, cupric ion showed true catalytic activity in the overall process.the influence of various parameters on the performance of the treatment process has beenconsidered, such as ph, concentration o...

Currently, there is growing concern about minimizing the environmental impacts caused by generation of waste on water, soil, air pollution, and contamination environment in general. Magnesium oxide (MgO) nanoballs (NBs) were synthesized hydrothermal method followed a calcination process. The average size particles dispersed deionized water was 159.2 ± 70 nm. energy band gap calculated to be 5.1...

background: similar to inflammatory cells, peripheral blood mononuclear cells (pbmcs) can also infiltrate in to kidney and urinary tracts and subsequently excreted by urine. in this study we determined the viability rate and response to phytohemagglutinin-a (pha) of human pbmcs in normal urine. methods: a number of 1×106 ficoll-hypaque isolated pbmcs were dispensed in 1 ml normal urine and 6 mo...

Layered double hydroxide (LDH) is an anionic clay material known to be effective as a catalyst for the photodegradation of dye organic pollutants. Zn/Al LDH was synthesized by coprecipitation then impregnated with metal oxides and calcined at 300oC form Zn/Al-TiO2 Zn/Al-ZnO catalysts congo red (CR). The characterization after preparation using SEM UV-DRS while that have been used in 5 regenerat...
