As an industrial economic organization with specific characteristics, industrial cluster is emerging with strong dynamism in global competition and driving the development of regional economy. However, industrial cluster can bring some negative impact on regional economy development. This paper tries to illustrate the reasons for the stagnation and degradation of resource-based regional industr...
with aim for Identification of contaminative and critical points of raw milk during production in 9 selected industrial dairy farms, 408 raw milk samples were collected from udders, milking machine, cooling tank and milk transport vehicle at receiving platform in dairy plant. Samples were examined for total microbial, coliform andE. coli count and also acidity and pH. Total microbial count of S...
The influence of TiO2 nano-particles (nano-TiO2) was studied relative to the mechanical and optical properties of CMYK printed paperboard after coating with a UV-curable varnish. Commercial duplex paperboard (glazed grayback paperboard, 230 g/m) was printed with a CMYK offset printing process. Board samples were coated with a nano-TiO2 modified UV-curable varnish at four treatment levels (0, 0....

BACKGROUND Listeria monocytogenes is of major concern to the food industry in general and the dairy industry in particular. Little is known about incidence of this pathogenic bacterium in dairy products in Iran. METHODS A survey was made from 23 September 2006 to 22 June 2007 for Listeria species in ninety samples of traditional and industrial cheeses, in milk and surface where the cheeses we...
Styrene is a compound commonly used in several industries, especially in those that manufacture glass-reinforced products. A thermal desorption-gas chromatography-mass spectrometry method for determination of styrene in industrial indoor and outdoor air is presented. Split valves of the thermal desorption unit were fixed at flows of 150 mL/min for indoor air and 5.3 mL/min for outdoor air, whic...
industrial activities lead to an increase in heavy metal burden in rivers. sediment and algae (spirogyra sp.) samples were collected from the shoor river to investigate their heavy metal concentrations. dry and ashed samples of algae and sediment were digested using concentrated nitric acid. heavy metals (as, fe, zn and cr) concentration measured using an icp-oes instrument (perkinelmer, usa). ...
This study aimed at assessing the toxic effects of industrial effluents using duckweed (Lemna minor L.) plants as a test system. Growth inhibition test according to standardized protocol (ISO 20079) was performed. The suitability of the Comet assay (indicates DNA damage) and certain parameters such as peroxidase activity and lipid peroxidation level, as biomarkers for environmental monitoring w...
