It has been suggested that the evaluation of specific blood parameters can be used as indicators of animal health and welfare. The aim of this study was to determine possible differences in these parameters at the beginning and at the end of the feedlot period and to analyse the influence of feedlot conditions on these animals. Blood parameter ranges can vary widely depending on factors such as transport, handling and feedlot. Four hundred and ten fattening lambs were studied to establish average values of different blood parameters. For data analysis, descriptive statistics and paired t-tests were used. The results of the current study indicate that mean values of Haematocrit, Cellular Haemoglobin Concentration and Cortisol levels were outside of the normal range, both at the beginning of the feedlot period and at upon leaving the feedlot. Higher mean values of MCHC, Urea, Total Proteins and Cortisol levels were observed at the end compared to the beginning of the feedlot period. On the other hand, Haematocrit, Mean Corpuscular Volume (MCV), Eosinophils and Creatine phosphokinase (CPK) were at higher mean values at the beginning of the feedlot period. Elevations in some blood parameters that are associated with acute stress states were raised in slaughter lambs during the feedlot period, transport and handling.

The Impact

AbstractFragmented habitats generally harbour small populations that are potentially more prone to local extinctions caused by biotic factors such as parasites. We evaluated the effects of botflies (Cuterebra apicalis) on naturally fragmented populations of the gracile mouse opossum (Gracilinanus agilis). We examined how sex, food supplementation experiment, season and daily climatic variables affected body condition and haemoglobin concentration in animals that were parasitized or not by botflies. Although parasitism did not affect body condition, haemoglobin concentrations were lower in parasitized animals. Among the non-parasitized individuals, haemoglobin concentration increased with the increase of maximum temperature and the decrease of relative humidity, a climatic pattern found at the peak of the dry season. However, among parasitized animals, the opposite relationship between haemoglobin concentration and relative humidity occurred, as a consequence of parasite-induced anaemia interacting with dehydration as an additional stressor. We conclude that it is critical to assess how climate affects animal health (through blood parameters) to understand the population consequences of parasitism on the survival of individuals and hence of small population viability.

A hundred adult of tilapia, Oreochromis niloticus, were inoculated intraperitoneally with 10(8) c.f.u. of Mycobacterium marinum. Other 100 speciemns were maintained without inoculation. Blood samples of six inoculated animals were collected at 01, 03, 07, 14, 21, 28, 35, 42, 49, 56 and 84 days after inoculation. Initially, six specimens were taken from the non inoculated group ("time zero"). The haematological parameters determined were: haematocrit (Hct), haemoglobin concentration (Hgb), total erythrocytes count (RBC), hematological indexes (MCV, MCH and MCHC), thrombocyte count (Tr), leukocyte count (WBC) and leukocyte differential count. There were no changes in Hct, Hgb, MCH and MCHC. However, the mean values for RBC and MCV decreased. The mean values for RBC and Hct of specimens from the "time zero" group were higher and the MCV and MCH lower than in inoculated animals. Occurred neutrophilia, and, at 72 h there was lymphocytosis and neutropenia. By the 49th day after bacterial inoculation, there was monocytosis.

In this study it is aimed to compare form blood parameters lipid and lipoprotein values of wrestlers and skiers who have different training levels. In addition, was to examine the risks of cardiovascular diseases for wrestler and skiers. In order to achieve this purpose, 33 male of elite wrestling and ski athletes measured in the study. In this study, Triglyceride (TG), were determined Total Cholesterol (TC), HDL-C and LDL-C levels (With Hitachi 717 autoanalyser). To determine the differences between groups “independent t” tests were performed.In this study, there were significant differences in plasma LDL-C, HDL-C, and TC values between wrestlers and skiers (p<.05 and p<0,001). There were no significant differences in plasma TG values between wrestlers and skiers (p>.05). In this study, HLC values of skiers were found to be significantly higher than wrestlers (p<0.001). In this study the cardiovascular risk ratios (TC/HDL-C) were found to be 3.39 mg/100cc for wrestlers and 2.80 mg/100cc for skiers. Ratios LDL-C/HDL-C were found 1.76 mg/100cc for wrestlers and 1.45 mg/100cc for skiers.Conclusion: Although the wrestlers’ training levels were always found to be difference than the skiers, TG values were not found to be different. But the HDL-C, LDL-C, and TC levels of skiers were found better than wrestlers. This results shows that medium and high level of different exercises did cause little differences in blood plasma lipid and lipoprotein levels. Plasma Lipid and lipoprotein values of the wrestler and skiers was accept good.  Wrestling and ski athletes would not be exposed to risk of cardiovascular diseases. Blood parameter values should be examined separately on Cross-country skiers and alpine skiers.

The biochemical blood parameters characterizing the students ’nutritional status were evaluated: protein, lipid, carbohydrate metabolism, a number of minerals. The mean values, errors of the mean, median (Me), boundary (Q) and the range of 25–75 percentiles were determined. In 9.1 % of students and 28.6 % of students, the total protein was increased. Creatinine in men was in the upper normal range, in women — at the upper limit of normal, of which 46.2 % was higher than normal. The interval Q25–75 of uric acid in students is determined in the lower normal zone. In 40.0 % of men, decreased high-density lipoprotein cholesterol (Q25–75 corresponded to 1.15–1.79), in women — below normal, Q25–75 5 was 1.3–1.5, decreased in 73.3 %. Me and Q25–75 iron were in the lower normal range; 14.1 % of men and 13.2 % of women are below normal. Me sodium and potassium at the level of the lower boundary of the norm, Q25–75 in the lower zone of the norm: in 16.0 % and 15.4 % of students the levels are reduced. Calcium is slightly above the lower limit of the norm, Q25–75–2.1–2.24, indicating an insufficient intake in the whole group; 25.0 % are below normal. The border of the 25th percentile of magnesium is at the level of the lower border of the norm, in 19.2 % it is reduced. 7.2 % lack of chlorine. Phosphorus is normal, but Q25–75 is in the upper zone; 17.9 % increased. Biochemical markers can identify individuals with metabolic disorders of nutrients. Statistical indicators — the median, the boundaries of 25–75 quartiles and their scope characterize the metabolism of macronutrients and minerals in the group and subgroups of students. Laboratory and mathematical methods can provide a basis for identifying the specific causes of these changes. For this, you can use the questionnaire method of studying the nutrition of students, possibly using the developed questionnaires for a specific situation.

The integration manufacturing technology is a kind of compound precision finishing process that combined grinding with abrasive jet finishing, in which inject slurry of abrasive and liquid solvent into grinding zone between grinding wheel and work surface under no radial feed condition when workpiece grinding were accomplished. The abrasive particles are driven and energized by the rotating grinding wheel and liquid hydrodynamic pressure and increased slurry speed between grinding wheel and work surface to achieve micro removal finishing. In the paper, the machining process validity was verified by experimental investigation. Experiments were performed with plane grinder M7120 and workpiece material 40Cr steel which was ground with the surface roughness mean values of Ra=0.6μm. The machined surface morphology was studied using Scanning Electron Microscope (SEM) and metallography microscope and microcosmic geometry parameters were measured with TALYSURF5 instrument respectively. The experimental results show the novelty process method, not only can obviously diminish longitudinal geometry parameter values of ground surface, but also can attain isotropy surface and uniformity veins at parallel and perpendicular machining direction. Furthermore, the finished surface has little comparability compared to grinding machining surface and the process validity was verified.

Age, sex and seasonal related changes in body weight and blood parameters were determined for T caninus and T. vulpecula, whose distribution overlapped in part of the study area. In T. caninus age-related changes occurred in body weight, mean plasma glucose and protein concentrations and haematocrit. Seasonal changes occurred in plasma glucose and protein concentrations, haemoglobin concentration and red blood cell count. There were sexual dimorphisms in haematocrit, haemoglobin concentration and red blood cell count in both species; the mean values were greater in males. T. vulpecula also exhibited a sexual dimorphism in body weight (males > females). The only seasonal change in T. vulpecula was in haemoglobin concentration. Comparison of the species as adults showed that T. caninus had higher mean levels of body weight, haematocrit and haemoglobin concentration, while plasma lipid concentration and red blood cell counts were greater in T vulpecula. These species differences may be a reflection of the diets of the two species. In addition the measured parameters showed greater seasonal variation in T. caninus, a K-selected species, than in T. vulpecula, which is more r-selected.

Extreme smog can have potentially harmful effects on human health, the economy and daily life. However, the average (mean) values do not provide strategically useful information on the hazard analysis and control of extreme smog. This article investigates China's smog extremes by applying extreme value analysis to hourly PM2.5 data from 2014 to 2016 obtained from monitoring stations across China. By fitting a generalized extreme value (GEV) distribution to exceedances over a station-specific extreme smog level at each monitoring location, all study stations are grouped into eight different categories based on the estimated mean and shape parameter values of fitted GEV distributions. The extreme features characterized by the mean of the fitted extreme value distribution, the maximum frequency and the tail index of extreme smog at each location are analysed. These features can provide useful information for central/local government to conduct differentiated treatments in cities within different categories and conduct similar prevention goals and control strategies among those cities belonging to the same category in a range of areas. Furthermore, hazardous hours, breaking probability and the 1-year return level of each station are demonstrated by category, based on which the future control and reduction targets of extreme smog are proposed for the cities of Beijing, Tianjin and Hebei as an example.

The paper presents selected test results of asphalt mixture conducted in low temperatures. The obtained parameters are highly diverse. It concerns ultimate breaking loads, stiffness parameters related to Young's modulus but also the fracture course. Statistical analysis upon the results makes it possible to relevantly estimate the material-defining parameter values. Such a random approach leads to the mean values of breaking and fracture-triggering loads, dealing with their dispersion too. The estimated parameters allow to form appropriate numerical models of asphalt mixture specimens. This type of analysis supports the laboratory tests. The paper presents the authors' simplified model considering non-uniform material features. The results reflect the scatter of real laboratory test outcomes. In order to do so an algorithm to calibrate the numerical model parameters was created.
