| Evapotranspiration covers are key to minimizing water percolation in waste systems. On potash tailings piles, evapotranspiration covers are important because they may decrease the leaching of brines generated from precipitation erosion. Considering this, the water deficit of four different potash tailings piles covering materials were evaluated using the CropWat model. This study was based on a lysimeter experiment carried out in Heringen, Germany. The experiment consisted of 4 different technogenic substrates made of municipal incineration wastes and coal combustion residues covered with a mixture of perennial grasses. By using the FAO CropWat model, the effective precipitation, crop evapotranspiration, actual evapotranspiration and the water deficit were... |

| Studies across the globe have shown that at least 3 out of 5 milkers experience pain in the musculoskeletal system (MSS), mostly in the upper extremities (DOUPHRATE et al., 2014, JAKOB, 2011, KOLSTRUP, 2012, PINZKE, 2003, TUURE & ALASUUTARI, 2009, KAUKE et al., 2010, THINIUS, 2012). The World Health Organisation (WHO) defines health as a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity. It is well known that dairy farming, and milking in particular is coupled with several risk factors for developing musculoskeletal disorders (KOLSTRUP, 2012). Technical measures seem to be insufficient to avoid physical overload. Therefore a more comprehensive approach seems to be necessary. In this study, four... |

| In the current dairy industry, an intensive demand for estrus detection and early diagnosis of pregnancy has been increasing. Progesterone is a steroid hormone that is secreted from corpus luteum into bovine blood and milk, and has a role of maintenance of estrus cycle and pregnancy. Therefore, progesterone concentration in bovine milk is used as an important indicator of estrus detection and early diagnosis of pregnancy. Current method for milk progesterone determination requires a hormone extraction procedure that is time consuming, various types of instruments, reagents management, and various assay methods that are destructive in nature. In contrast, near-infrared spectroscopy (NIRS) is a time saving and non-destructive analytical method that can be... |

| ABSTRACTThere is an inevitable decline in quality value of ascorbic acid in storage and distribution of cashew apple juice. The quality value and maximum shelf life of yellow sample of cashew apple juice were estimated and the quality value model based on the deteriorative factors was developed. It was discovered that balancing these factors led to satisfactory quality control of ascorbic acid degradation in cashew fruit juice during non refrigeration storage conditions and the distribution. Data were drawn from 34 full factorial experiments conducted in three replicates with the order of the replicates randomized. A multivariate regression analysis was used for relating the variables. The results of the experiment and the model developed for yellow... |
