Opis:
In this paper, we investigate the statistical features of the weighted international-trade network. By finding the maximum weight spanning trees for this network we make the extraction of the truly relevant connections forming the network's backbone. We discuss the role of large-sized countries (strongest economies) in the tree. Finally, we compare the topological properties of this backbone to the maximum weight spanning trees obtained from the gravity model of trade. We show that the model correctly reproduces the backbone of the real-world economy.

Opis:
Introduction: Women’s daily nutrition should include proper amounts of vitamins, ingredients and fluids. The shortage or surplus of any ingredient can negatively affect the health condition of a mother or hera baby Objective: The objective of the study was to assess the quality of the diet of pregnant wome in Poland against the World Health Organization (WHO) and European Union (EU) recommendations concerning requirements for vitamins and minerals. Methodology: 512 pregnant women in their 20th -30th week of pregnancy took part in the research conducted by the means of observation of a 7-day diet. Consumed products were analyzed by the means of DIETETYK software developed by the Polish National Food and Nutrition Institute (NFNI). Obtained micro- values were averaged. The results were compared with the recommendations of the WHO UE and NFN and analyzed statistically (test Chi2). Results: A lower consumption than 400g/day of fruit and vegetables in the diets was found in 4.68% of pregnant women. Mean values for vitamins: D – 2.64 ug/person, B6 – 1.76 mg/person and folic acid – 1603 ug/person, as well as average values for mineral components: calcium 689 mg/person, magnesium 255 mg/person, iron – 10.1 mg/person, zinc – 9.2 mg/person were also lower than daily recommended values. Daily level for sodium, phosphorus and vitamin A were exceeded. Conclusion: Results indicate insufficient knowledge of pregnant women about proper nutrition during pregnancy. Supplementing most vitamins and mineral components, beginning with a first pregnancy trimester, is necessary. Women at childbearing age must be educated about the necessity for proper nutrition during and before a pregnancy.

Opis:
Alcohol related harm is a global problem for public health where frequent consumption of large amounts of alcohol constitutes a serious health risk, particularly to vulnerable groups such as adolescents, pregnant women and newborns. The epidemiological study on health-lifestyle behaviour, especially alcohol consumption, was performed on a randomised group of post-partum women’s health behaviour during pregnancy, covering drinking habits, was undertaken in 2010, 2011 and 2012, (n=8,237) according to the PRAMS model including effects on the foetus and newborn; women being selected from obstetric and gynaecological wards. In this Polish study, only 14% of women did not consume alcohol before becoming pregnant while 15% of women drank alcohol throughout the entire period of pregnancy. In addition, awareness of the harmful effects of alcohol consumed, especially of small amounts, before and during pregnancy is low among Polish women. It is also alarming that more than 55% of physicians who provide care for pregnant women do not discuss with them the harmful effect of alcohol on the organism of the mother and foetus, whereas over 2% of doctors even recommend the consumption of alcohol in pregnancy. With reference to the Barker’s Foetal Origin of Diseases Hypothesis, the authors suggest such alcohol drinking behaviour of women during their reproductive ages and while pregnant may exert negative health effects on offspring, mainly in the form of susceptibility to contracting chronic diseases. Such findings pose a risk to future generations in Poland and require remedial/educational action targeted on health care professionals and public like.

Opis:
Motion of kink solitons in the φ$\text{}^{4}$ model in the presence of external spatially inhomogeneous forces is studied. Depending on the system parameters various routes to chaos, i.e. Feigenbaum's scenario, type-I intermittency, and chaos-chaos intermittency are observed. Synchronization of chaotic solitons is investigated.

Opis:
The influence of water conditions on the condition and growth of tree stands has been analysed in the context of the climatic and hydrological functions forest plays. Long observational series obtained for precipitation, outflow and depths below the surface of the water table have been put together with measured increases in the breast-height diameters of Scots pines and the severity of crown defoliation observable in selected tree species growing on the Polish Lowland, in order to determine the overall scope to the reaction stand condition manifests in the face of ongoing variability of water conditions within forest. An overall improvement in the condition of stands over the last 20 years does not disguise several-year cyclicity to changes capable of shaping the situation, i.a. departures from long-term mean values for precipitation totals and groundwater levels. The condition of stands is seen to worsen in both dry and wet years. Analysis of the degree to which pine, spruce and broadleaved stands experience defoliation points to spruce stands responding most to extreme hydro-climatic conditions. Extreme situations as regards water resources were seen to involve a response over two-year time intervals in the case of coniferous stands. Unsurprisingly, optimal growing-season (June-September) precipitation totals correspond with long-term average figures, while being slightly higher for spruce (at 384 mm), than for Scots pine or broadleaved species (375 mm). The relationships reported gain confirmation in analysis of periodic change in breast-height diameter increments characterising Scots pines, whose growth is seen to depend closely, not only on precipitation, but also above all on the depth of the water table in the summer half-year. Optimal depths of the water table proved to be different, being around 20 cm below ground in the case of marshy coniferous forest, 80 cm in wet habitats, and 135 cm in fresh habitats. Depending on the possibilities for water to soak into the rooting zone of trees there were even twofold differences in measured growth increments in Scots pine (as the dominant species in Poland’s lowland habitats). The maintenance of stable water conditions (as the most variable environmental factor in forest) should be an overriding aim of management activity in this habitat. When account is taken of the influence of the state of water resources on biomass production, and then on the intensity of evapotranspiration and the absorption of carbon dioxide from the atmosphere, it is seen how important it is to achieve improvements in water conditions in forests, as such an important factor in combating climate change.
