Wet ageing is the most commonly used ageing sistem by the meat industry to improve tenderness, which results in a more homogeneous product with high consumer acceptability. The aim of this study is to determine the influence of wet ageing duration on beef quality characteristics, at refrigeration temperatures (0 - 5°C). The meat samples were kept under refrigeration conditions for 2, 7, 12, 17, 21 days. After each period, there were monitored: the textural parameters (hardness, adhesiveness, springiness, cohesiven...

The increased vulnerability of the aquatic landscapes of Subarctic of the European part of Russia to anthropogenic impact is a consequence of natural conditions and its geographical location. In this regard, the study of small rivers and their catchments which are remote from the direct influence of the industrial and residential zones is of particular interest to researchers, since they can be considered as background areas of the Subarctic. One of these rivers is Kyanda flowing into the Onega Bay of the White Se...

The regularities of distribution of methane and sulfide sulfur (total sulfide ? ?H2S) in the bottom sediment deposits of therapeutic sulfide mud Lake Bolshoy (Big) Tambukan, located in the region of Caucasian Mineral Waters. Determination of methane and sulfide sulfur were produced in black and dark grey therapeutic mud, as well as in the underlying steel-grey clays and coastal sediments, represented by yellow-brown clay and loam. The formation of therapeutic sulfide mud flows through the biogeochemical environmen...

The results of Chembursky lake, Vityazevsky, Kiziltashsky and Bugazsky coastal salt lakes expeditionary research are observed, aimed to examine the allocation of methane and sulfur sulfide (total sulfide) according to the vertical cut of bottom sediments (sulfidic muds), and also the value of Eh and pH. pH and Eh values in the examined horizons of coastal salt lakes bottom sediments vary correspondingly in the limits from 7.33?8.06 and -198?-2.5 mV, in the Chembursky lake sediments ? 7.47?7.64 ? -78?+46 mV. CH4 an...

The results of methane and total hydrogen sulphide detection in bottom sediments of small rivers as well as fresh and slightly saline water bodies of the Eastern Donbass are presented. The content of CH4 in sediments of water bodies of Eastern Donbass varies between 0.04-26.8 ?g/g wet mass (w.m.), ?H2S content varies from to less 0.005 than 4.02 mg/g w.m. The maximum concentrations of methane were recorded in the bottom sediments of the Glubokaya River (Station No. 7), while the maximum of the content ?H2S is conf...

Determination of soil properties is based on soil sampling with low resolution (1- 2 or more samples per hectare) and their analysis in the laboratory. This method does not provide sufficient data to highlight the significant variability of the soil properties for the analysed parcel. This leads to a uniform distribution of the nutrients that can also be synthetic chemical substances (pollutants). Since the soil properties can influence plants growth, high-resolution mapping is required by the help of some sensors...
