Available world-wide literature numerical data and functional relationships allowing to determine thermophysical properties of whole or comminuted fruits and vegetables in the drying, heating (e.g. in pasterrization, sterilization, blanching, damping, deaeration) or cooling processes are analyzed.
The suitability of selected satellite vegetation indices for estimating the condition of cereals in Poland was investigated. The indices presented here were derived from the data stored in INFOSAT database, which was created at the Institute of Geodesy and Cartography. INFOSAT contains data from processed satellite images acquired by NOAA AVHRR scanner. The methods applied in the database generation and in the calculation of vegetation indices were analysed in view of their applicability to the inference on crops condition over a large area. Presented results of statistical analysis indicate significant relations between the production of cereals and indices based on NDVI.

The purpose of the work was determination the area pollution influence on mineral compounds content in water of north and west part of Dejguny Lake. There was studied total-P, dissolved PO₄⁻³(V), NH₄⁺, NO₃⁻, NO₂⁻, total-Mg, total-Fe, SO₄⁻² and Cl⁻ concentration in water. The most compounds content was in I class of water cleanness. The higher content of nitrate compounds was near the recreation area of Kronowo village and, ammonium and nitrate nitrogen, total phosphorus, ortho dissolved reactive phosphates and magnesium(II), near agricultural area depend on their content in water near the forested area. Moreover, in lake near agricultural area water side was higher content of sulphates(VI) in II class of water cleanness.
The results of recent studies indicate that obesity is associated with an increase in peroxidation processes. The aim of the present study was to assess the degree of oxidative stress in obese women and to evaluate the relationship between selected markers of oxidative stress and body mass index. Study population consisted of 43 women aged 21 to 66. Subjects were divided into two groups according to their body mass index (BMI): Overweight group (BMI < 30 kg/m2) and Obese group (BMI > 30 kg/m2). Venous blood samples were taken from each subject after an overnight fast and following parameters were assessed: plasma total antioxidant status (TAS), plasma concentrations of thiobarbituric acid reactive substances (TBARS), serum levels of antibodies against oxidized low density lipoproteins (oLAB), serum lipid profiles, serum glucose and insulin concentrations. Additionally, serum low density lipoprotein (LDL) cholesterol and insulin resistance indices were calculated. Serum triglyceride concentrations, insulin levels and insulin resistance indices were significantly higher in obese women in comparison with overweight ones. No significant differences in TBARS concentrations, TAS and oLAB levels were found between the two study groups. However, oLAB titres in Obese group were above the upper limit of the reference range for healthy adults. In both study groups significant correlations (p <0.01) between BMI and levels of triglycerides, insulin concentrations and insulin resistance indices were observed. Additionally, positive correlations (p < 0.05) between BMI and LDL-cholesterol and diastolic blood pressure as well as negative correlations (p < 0.05) between HDL-cholesterol and diastolic blood pressure were found in Obese group. In the overweight women, there were positive correlations between oLAB levels and triglyceride and insulin concentrations, between oLAB titres and insulin resistance indices and between oLAB levels and systolic and diastolic blood pressure (p < 0.01 for all correlations). There was also a negative correlation between oLAB titres and TAS (p < 0.05). The results of the present study confirm that obesity is associated with oxidative stress. Oxidative stress may be the link between obesity and atherosclerosis.
