Resume Introduction L’education du patient est une des strategies therapeutiques recommandees pour le traitement de la lombalgie chronique. aux neurosciences douleur un courant educatif emergeant. Cependant ses contours restent flous. Cette revue exploratoire permettra : (1) d’identifier les preuves disponibles sur l’education dans patients lombalgiques chroniques ; (2) clarifier concept ; (3) ...

The clarification of mixed juice has been the subject of research for decades, due mostly to its large impact on sugar quality. Much, if not all, of the work has however been done on mixed juice originating from milling rather than from diffusion. This paper examines a back-to-basics, laboratory approach, involving cane juices produced from conditions simulating milling and diffusion. Furthermo...

Abstract: Commonly, for being done a numerical modeling of any natural phenomenon, like as water flow pattern, need to an exquisite and modify calculated mesh. For gaining this standard calculated mesh, different calculated meshes must be analyzed sensitively. Thus, the optimum calculated mesh could be selected. At the present paper, the first, a powerful two dimensional numerical model which i...

The objective of this paper is to complement the effluent quality (EQI) and operational cost (OCI) indices used to evaluate (plant-wide) control strategies in wastewater treatment systems with a new dimension dealing with greenhouse gas (GHG) emissions. The GHG evaluation is based on a set of comprehensive dynamic models that estimate the most significant potential on-site (secondary and sludge...

Membrane fouling is one of the main issues in membrane processes, leading to a progressive decrease of permeability. High fouling rates strongly reduce the productivity of the membrane plant, and negatively affect the surviving rate of the membrane modules, especially when real wastewater is treated. On the other hand, since selectivity must meet certain target requirements, fouling may lead to...

As global fisheries decline, microbial single-cell protein (SCP) produced from brewery process water has been highlighted as a potential source of protein for sustainable animal feed. However, biotechnological investigation of SCP is difficult because of the natural variation and complexity of microbial ecology in wastewater bioreactors. In this study, we investigate microbial response across a...

The technologies most commonly used for performing secondary treatment of municipal wastewater rely on microorganisms suspended in the wastewater to treat it. Although these technologies work well in many situations, they have several drawbacks, including the difficulty of growing the right types of microorganisms and the physical requirement of a large site. The use of microfiltration membrane...

Wastewater treatment plants (WWTPs) are important routes for releasing microplastics into the environment, with produced sludge acting as a recipient of from wastewater. There is little information on impact processes number in sludge. In this study, presence by Sari WWTP northern Iran was investigated. Samples were taken 3 replications and larger than 37 μm extracted. The primary settling tank...

Background & Aims of the Study: Industrial wastewater sludges must be disposed in a safe way because they have hazardous effects on the human and environment. The aim of this study is to investigate the physicochemical characteristics and disposal options of sludges from oil-water separator (OWS) and dissolved air flotation (DAF) clarifier of a Refinery wastewater treatment plant. Material...

The industrial process of continuous sedimentation of solid particles in a liquid takes place in a clarifier-thickener unit, which is a large tank with a feed inlet somewhere in the middle and outlets at the top and bottom. For half a century the constitutive assumption by Kynch has provided a platform from which steadystate mass-balance considerations have been used to obtain rules and graphic...
