The aim of this study was to evaluate the goat milk mineral performance concentrated by block freeze concentration process. Twenty batches of skim goat milk, each one with one liter, were subjected until the third stage of the freeze concentration process. The initial skim goat milk, concentrated, and ice fractions obtained were analyzed by calcium, magnesium, zinc, phosphorus, sodium and potassium content. Results showed that phosphorus content not increased (P < 0.05) with the increase of freeze concentration stages, for concentrated and ice fractions. In the first stage of freeze concentration process, the magnesium element showed the higher (P < 0.05) efficiency (95%). However, the higher (P < 0.05) concentration factor was determinate to calcium element in the third stage of the process. Also, it was observed an increase in the minerals contents evaluated with the increasing of freeze concentration stages of skim goat milk. Based on results obtained in the present study, the skim goat milk concentrated obtained in the first stage showed the best performance of skim goat milk mineral content concentration.

The region of Warmia and Mazury is characterized by the special diversity and richness of its natural environment, including large forest complexes, where wild mushrooms are commonly collected and consumed. This study aimed to examine the differences in mineral content (calcium, magnesium, sodium, potassium, iron, zinc, copper, manganese) of three species of mushrooms collected in north-eastern Poland. The research material consisted of dried samples of king bolete (Boletus edulis), bay bolete (Boletus badius), and chanterelle (Cantharellus cibarius) collected in the region of Warmia and Mazury. The content of the above-mentioned elements in mushroom fruit bodies was determined using the flame atomic absorption spectrometry (acetylene-air flame) and the emission technique (acetylene-air flame) for sodium and potassium. For the majority of micro- and macroelements, the studies confirmed the presence of significant differences in their content, depending on the species of fungi. The studied mushrooms cover a significant percentage of daily demand for many of the minerals. This concerns mainly copper, zinc, and potassium, although none of the species was a good source of calcium and sodium. Among the analyzed mushrooms, chanterelle is the best source of most minerals.

Proximate  composition  and  mineral content of  five species of edible mushrooms namely Pleurotus ostreatus, Pleurotus sajor-caju, Pleurotus florida and Pleurotus HK- 51 belonging to the family: Pleurotaceae and genus: Pleurotus and  Calocybe indica belonging to the family: Tricholomataceae and Genus: Calocybe have been analyzed.Crude protein, total lipids, available carbohydrates, dietary fiber and total carbohydrates  content  in mushrooms  were found to be in the ranges of 3.22-4.83, 0.41-1.05, 4.2-6.37, 0.58-1.11 and 4.82-7.48 g per 100g of fresh edible portion(EP) respectively.  Moisture, total solids and ash content  were found to be in the ranges of 85.95-90.07, 9.93-14.05 and 0.98-2.3 g/100g of fresh EP respectively. Where as total  calorie values in mushrooms  were found to be in the ranges of  35.51 - 50.03 Kcal / 100g  fresh  EP. The values of  Zinc, copper,  iron,  sodium  and  potassium content in mushrooms were found to be in the ranges of 0.65-1.24, 0.14-0.91, 0.94- 1.81, 3.18-37.23 and 19.83-197.24 mg/100g of fresh EP respectively while calcium, magnesium,  phosphorus  and  manganese content were  in the ranges of  0.12-0.58, 27.26-51.21, 22.2-62.1 and  0.17-0.53 mg/100g of fresh EP respectively.

In the experiment carried out on three groups of dry cows 6 goals in each, the influence of introducing of Trutenat to them on the content of Zincum, Cuprum and Mangan in carunculs of the placenta maternal part and the course of calving researched. The drug is not introduced to cows of control groups, the first group with course of physiological calving and the third at detention of the placenta, and the second group was injected three times at intervals of 7 days, were injected subcutaneously Trutenat in a dose of 7 ml/100 kg of body weight. At all cows throughout 30–45 minutes after birth of the calf we exterpited 2 caruncles, in which we determined the mineral content. The level fluctuation of the test substances in carunculs depending on the current third stage of calving set. The concentration of Zincum in carunculs of cows during the detention of the placenta is higher than in cows of the second (experimental) and the first (control) groups, and Cuprum is lower compared to the first and the second control group, Mangan – below relative to both control groups.The physiological calving courses with different concentration of Zn (61.45 ± 1.34 μmol/l), Cu (0.73 ± 0.1 μmol/l) and Mn (213.3 ± 2.7 μmol/l) in carunculs of the placenta maternal part. The second stage of calving of all cows was within the physiological framework without rendering assistance, ranged from 57 to 85 minutes and amounted 67.5 minutes to an average.Depending on the duration of the third stage of calving we determined the relationship of the studied mineral substances between their levels in blood and maternal parts of the placenta. On the pathology of the third stage of calving in cows blood in the first stage the level of Zinc amounted to 134.15 µg%, Cuprum –90.8 µg %, Mangan –to 3.7 µg%. Separation of the placenta lasted longer for 20–22 hours.

Foliar and litter mineral content of six common and economically useful trees of tropical West Africa along with the associated soils were determined. Individual cations varied considerably, and seasonal changes in leaf as well as soil magnesium, sodium, and potassium content were not marked. Foliar nitrogen was maximum in the species studied compared with other foliar cations. Foliar calcium, potassium, and nitrogen were greater than that of magnesium, sodium, and phosphorus, respectively. Litter of Chlorophoraregia A. chev. and Afzeliaafricana Sm. is comparatively richer in nutrients, especially nitrogen. A significant positive linear correlation coefficient has been observed between leaf and litter magnesium as well as between soil and leaf, and for calcium, magnesium, and phosphorus between litter and soil for certain trees. However, the correlation is negative for magnesium between litter and soil in the case of Triplochitonscleroxylon K. Schum.

Critics have argued that Elizabeth Gaskell's first novel, Mary Barton (1848), is split by a conflict between the modes of realism and romance. But the conflict does not render the novel incoherent, because Gaskell surpasses both modes through a utopian narrative that breaks with the conflict of form and gives coherence to the whole novel. Gaskell not only depicts what Thomas Carlyle called the ‘Condition of England’ in her work but also develops, through three stages, the utopia that will redeem this condition. The first stage is romantic nostalgia, a backward glance at Eden from the countryside surrounding Manchester. The second stage occurs in Manchester, as Gaskell mixes romance with a realistic mode, tracing a utopian drive toward death. The third stage is the utopian break with romantic and realistic accounts of the Condition of England and with the inadequate preceding conceptions of utopia. This third stage transforms narrative modes and figures a new mode of production.

The aim of the research project solved at the University of Finance and administration is to construct a new bankruptcy model. The intention is to use data of the firms that have to cease their activities due to bankruptcy. The most common method for bankruptcy model construction is multivariate discriminant analyses (MDA). It allows to derive the indicators most sensitive to the future companies’ failure as a parts of the bankruptcy model. One of the assumptions for using the MDA method and reassuring the reliable results is the normal distribution and independence of the input data. The results of verification of this assumption as the third stage of the project are presented in this article. We have revealed that this assumption is met only in a few selected indicators. Better results were achieved in the indicators in the set of prosperous companies and one year prior the failure. The selected indicators intended for the bankruptcy model construction thus cannot be considered as suitable for using the MDA method.
