The minimum to maximum temperature value was observed 22ºC 25.2ºC while pH ranged between 7.2 (P-9) 7.9 (P-1) . Turbidity 5 (P-7) 17.9 (P-11) NTU. TDS 1540 (P-10) 4950 (mg/l (P-4). and Total Hardness 240 (P-3) 1250 mg/l Calcium 75(P-3) 436 (P-9). Magnesium 25.6 (P-6) 139 highly positive correlated were found total hardness (0.944) , Chloride (0.913). Highly negatively were, (-0.640).The result ...

Aim of the study: The aim study was to evaluate changes in concentration selected ions waters Słupsko dam reservoir and determine its role as a "primary sedimentation tank" for Pławniowice reservoir. Material methods: Determination factors causing these made on basis measuring number physical chemical parameters between March 2019 February 2020. research carried out terms checking potential unf...

The present study was conducted to analyze the physico-chemical and colour properties of emu meat. The leg, back and breast portion along with a uniform mix of these three cuts were taken for evaluation of emu meat quality in respect to various physico-chemical parameters. The pH of breast meat was found significantly (P<0.05) lower than meat from leg and back portion. Water holding capacity of...

Nanotechnology is one of the key technologies of the 21st century. Already by now, many products containing manufactured nanomaterials (NMs) have entered the market. Most industrial applications are based on just a few NM types, mostly metals and metal oxides. However, by varying size, shape or surface chemistry a large number of variants can be produced. Variations of physico-chemical paramete...

In order to simulate a contamination at the processing plant, one batch of freshly-processed salami batter (20 kg) was inoculated (1% v:w) with 5 log colony forming unit (CFU)/g of a multi-strain cocktail of two strains of Escherichia coli O157:H7 (registered and wild strain). Another batch was inoculated (1% v:w) with sterile physiological saline solution and used to check the lactic acid bact...

the design and manufacture of direct smelting reactors depends on the rate of the physico-chemical reactions that occur in the particles immersed into the molten bath. investigation of the effects of the important parameters that influence the smelting rate of the particles that in the furnace are both difficult and expensive if the aimed is to take measure meuts under real practical conditions...

honey is the natural sweet substance produced by honey bees from nectar of plants or from secrerations of living parts of plants or excretions of plants sucking insects on the living pans of plants. physico-chemical properties of honeys in each region are related to kind of plant and flower.therefore ,knowing of component is very important. in this study thirty samples of honey were collected f...

Quantitative Structure-Property Relationships (QSPR) are predictive methods of macroscopic properties of substances based on their only molecular structures. If these methods were initially mainly devoted to biology and toxicology, they are nowadays increasingly used for the prediction of physico-chemical properties. In the framework of the European REACH regulation (2006), their developments a...

Laboratory studies were conducted to investigate scrap-tire-shreds as a potential alternative to conventional gravel in the drainage layer of leachate collection system at the base of landfill. Performance of various physico-chemical characteristics of leachate after passing it through combined bed of scrap-tire-shreds and gravel for different combinations of thickness of scrap-tireshreds and g...
