since it was first diagnosed in 1914 in marrakesh, schistosomiasis has been a public health problem in morocco for decades. a national control program launched in 1982 has led to a considerable reduction in the incidence and morbidity associated with the disease. consequently, the program has shifted from disease control to an elimination process launched in 1994. this process aimed to eliminat...

background: baits have become popular and effective formulations against urban insect pests. compared with re­sidual sprays toxic gel baits are used more and more frequently to control urban cockroach populations. the aim of this study was to investigate the usage of two commercially available fipronil and imidacloprid gel bait formulations against blattella germanica field infested in iran. me...

conclusions affordable new hcv treatment regimens are available in iran, providing an opportunity for hcv elimination. recommendations provided in this current national guideline can facilitate evidence-based management of hcv infection. results pegylated interferon alpha (pegifn), ribavirin (rbv), sofosbuvir (sof), ledipasvir (ldv) and daclatasvir (dcv) are currently available in iran. pre-tre...

Gas-phase biofilters used for the treatment of waste gases were originally packed with compost or other natural filter beds containing indigenous microorganisms. Over the past decade much effort has been made to develop new carrier materials, more performant biocatalysts and new types of bioreactors. Elimination capacities reached nowadays are 5 to 10 times higher than those originally reported...

The objective of this paper is to propose a new autonomous model for the use of GPS devices that tightly coupled with GIS, to address the necessary framework and techniques needed to plan, design, and implement an assessment tool for solving problems associated with marine environment in Alexandria Bay. This work also aims at analyzing the data of the proposed system towards the elimination of ...

Reedswamps meet three important functions in landscape ecology: They act as a structural element and as a food-plant for a highly specialized fauna (species protection), the rhizomes stabilize the sediment and the stalks dissipate the wave energy (shore protection), and they improve the conditions for an enhanced microbial decomposition of an external organic load and an elimination or fIXation...

As the principal objective, this present study compares the purifying performances of the membrane bioreactor (MBR) with the conventional activated sludge used from the wastewater treatment plant of Beni Messous (Algiers) with the average characteristics in the chemical oxygen demand being 586 mg/L and 188 mg/L in the biochemical oxygen demand and 14 NTU of turbidity. The membrane bioreactor re...

To stay competitive, companies facing today’s levels of unprecedented global competition must design and offer better products and services and improve their manufacturing operations. Lean manufacturing has been used to improve operational performance. Operations management is concerned with converting materials and labor into goods and services as efficiently as possible to maximize the profit...

Abstract Microplastic pollution of water and ecosystem is attracting continued attention worldwide. Due to their small sizes (≤5 mm) microplastic particles can be discharged the environment from treated wastewater effluents. As microplastics have polluted most our aquatic ecosystems, often finding its way into drinking water, there urgent need find new solutions for tackling menace pollution. I...

The article is devoted to the scientific and theoretical analysis of current state legal provision drinking water quality in rural areas. It was stated that recent years there has been a steady trend deteriorating used for areas, including due increasing levels nitrate pollution. Proposals have made for: further implementation Council Directive 98/83 / EU on intended human consumption 91/676/ E...
