Background: Textile industries play a significant role in the economic growth of the country. Health concern of these textile mill workers is the biggest challenge. Respiratory alterations were found in these workers with long-term exposure to cotton dust. Effect of cotton dust on peak expiratory flow rate (PEFR) is not very well documented in the past. Aim/Objective: The main objective of this...

Abstract The Mediterranean cypress ( Cupressus sempervirens ) is an evergreen conifer that belongs to the Cupressaceae, which first plant family whose detailed evolutionary history traces break-up of supercontinent Pangaea roughly 150 million years ago. broad and deep economic socio-cultural significance species began in at least third millennium BCE. This interdisciplinary review highlights tr...

To facilitate the manufacturing of a ball-end mill, this paper presents an algorithm for ball-end mills gashing by using a five-axis computer numerical control (CNC) grinding machine. In this study, the normal helix models are proposed. Then, based on the cutting edge geometric model and the machining mode of the five-axis computer numerical control (CNC) grinding machine, the coordinate of the...

This paper presents a feedforward control concept for lateral asymmetries in heavyplate hot rolling. A lateral off-center plate position generally entails asymmetric rolling forces, asymmetric mill stretch, and thus a wedge-shaped exit thickness that may cause a cambered plate contour and a rotatory motion of the plate. In this paper, a model of the mill stand and of the plate movement is prese...

Olive-oil production is of vital importance for the economy and social life of the Mediterranean region; however, the side effect of the olive-oil mill activity is the generation of enormous quantities of biotoxic olive-mill waste within a short period of three months. Numerous physicochemical and biological methods have been used in the past for the treatment of both olive mill wastewater (OMW...

The closure of water circuits within pulp and paper mills has resulted in a higher contamination load of the final mill effluent, which must consequently be further treated in many cases to meet the standards imposed by the legislation in force. Different treatment strategies based on advanced oxidation processes (ozonation and TiO2-photocatalysis), and their combination with biological treatme...

Malnutrition is a major problem for rural areas of Sub-Saharan Africa. Technology such as the maize mill, which alleviates the burden of pounding grain, also introduces opportunities and new challenges for improved nutrition. While there have been many technical studies of grain mills, and maize mills are in operation in hundreds of locations throughout Sub-Saharan Africa, the maize mill has no...

Neuronal network flexibility enables animals to respond appropriately to changes in their internal and external states. We are using the isolated crab stomatogastric nervous system to determine how extrinsic inputs contribute to network flexibility. The stomatogastric system includes the well-characterized gastric mill (chewing) and pyloric (filtering of chewed food) motor circuits in the stoma...

Fine cohesive powders are often dry granulated to improve their flowability. Roller compaction is commonly used to produce dense ribbons which are then milled. The material properties of the powder and the conditions in the roller compactor affect the strength of the ribbons, however there is no method in the literature to predict the size distribution of the product of ribbon milling. Here we ...

Olive mill wastes (OMWs) are high-strength organic effluents, which upon disposal can degrade soil and water quality, negatively affecting aquatic and terrestrial ecosystems. The main purpose of this review paper is to provide an up-to-date knowledge concerning the microbial communities identified over the past 20 years in olive mill wastes using both culture-dependent and independent approache...
