Opis:
The interest in biogas production in Poland is growing rapidly. This is mostly due to the fact that there is a need for handling and managing the increasing quantities of diverse bio-waste generated by industry and agriculture. Therefore, good laboratory practices and correct preparation of batch tests are very important for planning of a full-scale biogas plant. The aim of the paper was to determine the effect of mixing in the laboratory batch reactors on the biogas yield of maize straw under thermophilic conditions. The scope of this work included: (1) the analysis of basic physical and chemical parameters and (2) laboratory determination of biogas and methane yield from anaerobic digestion of maize straw with different frequencies of mixing. The obtained biogas and methane yield from the thermophilic fermentation of maize straw mixed every day was 381.89 m3·Mg-1 FM and 184.97 m3·Mg-1 FM, respectively. The results of this study confirmed the effect of no mixing inside reactors. In the batch test a decrease in biogas and methane yields was observed, by approx. 60 m3·Mg-1 and approx. 28 m3·Mg-1, respectively.

Opis:
This paper presents the comparison of efficacy of three selected methods of texture analysis: Grey Level Co-occurence Matrix (GLCM) based entropy, Laplace operations and granulometric analysis, in the context of the edge effect. This effect means identifying edges of objects in an image as places of high texture, regardless of the real nature of the texture of the objects. It can significantly decrease the efficacy of selected methods of texture analysis. The article provides a brief presentation of the principal cause of this effect and also, shortly, the basics of the tested methods of texture analysis. The experiments were carried out on the VHR satellite image Pleiades (2m GSD), on the selected samples (test areas) of four land use/cover classes having different texture. The separation of these test areas in different texture images was assessed using Jeffries-Matusita distance. The results prove the significance of impact of the edge effect on the selected methods of texture analysis (GLCM entropy and Laplace operations), but they also show that a granulometric analysis is generally insusceptible to this effect, and thereby it provides the best discrimination of land use/cover classes of different texture.

Opis:
The results of positron lifetime and ultrasonic velocity measurements in dilute aqueous pyridine (PYR) solutions show unusual changes in ultrasonic, annihilation data in function of pyridine concentration. The results obtained suggest that strong structural changes occur in the system, in the region of low pyridine concentrations. Liquid clathrate hydrates forming in the system are supposed with unusual stoichiometry and untypical geometry. They are supposed to be very short-living and/or unstable.

Background: The Regulation of the Minister of Health issued on 16th August 2018 addressed the matter of the organizational standard of perinatal care which determines guidelines concerning care of the newborn baby, in which skin-to-skin contact and early breastfeeding are important. Aim of the study: The aim of this study is to explore women’s preferences concerning care of the newborn in the immediate postpartum period. Material and methods: 130 patients attending the Pro-Familia specialist hospital in Rzeszow participated in this research. The cohort consisted of pregnant women who had attended the doctor supervising their pregnancy before delivery. The research was carried out from March to April 2013 and the data collected was statistically analyzed, assuming a significance level of p<0.05. Results: Pregnant women most often expressed a preference of an accompanying person to cut the newborn’s umbilical cord (59.2%), with 23.1% preferring a member of the medical team to do so. The majority (89.2%) of pregnant women wanted their baby to be laid on their stomach immediately following delivery to ensure skin-to-skin contact. In terms of Apgar scoring, 69.2% of women expected information about the Apgar score of their newborn immediately after delivery. Most women (60%) wished their newborn to be given routine vaccinations for hepatitis B and tuberculosis (BCG). Patients most often declare that they want to breastfeed exclusively (77.7%), with 29.2% of women expressing a wish to obtain more information about breastfeeding and 31.5% wishing to consult with a lactation specialist. Conclusions: Pregnant women expect skin-to-skin contact immediately after delivery, the umbilical cord to be cut by an accompanying person and would like to be told their newborn’s Apgar score. The women studied prefer exclusively breastfeeding, and express a wish to obtain information regarding lactation, and expect to be able to consult with a lactation specialist.

Opis:
The results of positron lifetime and ultrasonic velocity measurements in dilute aqueous dimethylsulfoxide (DMSO) solutions show the usual extreme characteristic for polar organic solutes. The results obtained suggest that strong structural changes occur in the system, in the region of low DMSO concentrations. Liquid clathrate hydrates forming in the system are supposed, with unusual stoichiometry and untypical geometry of the hydrates.
