Abstract the paper deals with verification of the effects of the electrolyzed NaCl-water solution where a new possibility for an alternative procedure to disinfect water is provided. The experiment was done in two chicken breeding halls where the solution was used to disinfect the stable premises and at the same time it was applied into the feed water. The effects of disinfection were verified directly in the stable premises at the interval of 20, 40, 60 minutes after application. Staphylococci and Streptococci and Enterococci were inactive always after 60 minutes of effect. There was significant decrease in the number of total number of microorganisms. An evaluation of the qualitative features of the produced chicken meat, focused mainly on the PSE meat disorder, was a part of the examination, too. After the research was finished, the chickens were slaughtered at the industrial slaughterhouse and samples of the meat were taken (gradually 157 pieces in total) from the individual halls and analysed. The determined share in water loss by dripping was the most significant of the monitored indicators, which could suggest a possible development of the PSE problem, however, the meat colour and the pH values did not confirmed this. The values of pH, colour and loss of water (dripping) ascertained, processed by the T-test did not confirm the hypothesis of the assumed possible differences in occurrence of critical values of these indicators in both groups observed.

ABSTRACT The growth of an eucalypt plantation should be monitored to identify factors that influence its development, helping in the decision-making process, aiming to reduce productivity losses. Thus, the objective of the present study was to evaluate the influence of the age of replanting on the yield and growth of eucalypt stands. The experiment was conducted in an area of CENIBRA S.A. Company, and established in a commercial plantation in August 2011. The application of herbicide and the ant control were performed in total area before planting. Seedlings of Eucalyptus urophylla × Eucalyptus grandis clones in 3.0 × 2.5 m spacing were used. Limestone (1,500 kg ha-1) was applied in total area before planting and 100 g plant-1 of NPK fertilizer (06-30-06) was applied immediately after planting. Four months after the installation of the experiment, 300 kg ha-1 of NPK (06-10-29) was applied. Treatments consisted of four dates of seedling replanting (0, 20, 40 and 80 days after planting) without complementary fertilization, and two treatments (replanting 40 and 80 days after planting) with supplementary fertilization (100g plant-1 NPK 06-30-06). The individual volume of replanting trees was 46.6% lower than of non-replanted ones. Treatments with complementary planting fertilization did not differ (p > 0.05) by the T-test. It is concluded that the longer the time between planting and replanting, the smaller the individual volume of the replanting trees and that the complementary fertilization in seedlings replanted does not favor their growth.

AbstractBackgroundGuidelines for venous blood sampling procedure (phlebotomy) discourage tourniquet use whenever possible. Here, we aimed to assess the Biomedical Scientists capability of not using the tourniquet in phlebotomy, which we hypothesized to be equal to 50% of the patients attended, and identifying the most frequent venipuncture site.Materials and MethodsWe selected and assigned two (BMS) with the same age (41 years) and experience (20 years) to record ten phlebotomy days, the first with prioritized and the latter with non-prioritized patients. In a simple record form, each acquired daily data for the number of attended patients, age and gender, the frequency of non-tourniquet usage and the punctured vein. To test our work hypothesis we used the two-tailed single sample t-test (p < 0.05). Differences between age-group means and non-tourniquet use means by each BMS were tested by two-tailed t-test for independent means (p < 0.05).ResultsIn 10 phlebotomy days 683 patients were attended, with males representing 43,2% of the population. We found no statistically difference between age-group means. The combined capability of non-tourniquet use was 50,5%, which did not differ from our null hypothesis, but the individual group-means were statistically different, being 33% and 66.9% in the prioritized vs non-prioritized group. The medial cubital vein was the most prone to be punctured (77,7%).ConclusionsWe have shown that performing phlebotomies without tourniquet use is possible and desirable in at least half of the attended patients, though being more limited in specific group populations. Our results provide room for quality improvement in the laboratory pre-analytical phase.Key points summaryWe assessed the capability of Biomedical Scientists not using the tourniquet in real life blood sampling procedures for diagnostic purposes.Blood was collected from at least half of the attended patients without tourniquet use.Biomedical Scientists were able to prioritize the antecubital veins without tourniquet application (medial cubital vein the most prone to be punctured - 78% of attempts).

Lying is considered a dangerous tendency among children if it has become a habit. It results in many social problems, such as child’s loss of confidence, lack of others’ respect to him, and his lack of respect to the desired values ​​of the society, such as honesty and trust. Consequently, he will be led to a deviation when he becomes old; especially if the child’s socially unaccepted behavior has not been directed. The research, thus, aims to examine the causes of lying in the most important stage of children’s life; that is, between (4-6) years. Such an aim helps to know about the individual reasons of lying among males and females from teachers’ perspectives. To meet the objective of the study, a number of (128) children has been randomly selected from the children of the Kindergarten Department during the academic year 2019-2020, together with (28) she-teachers. In addition, a questionnaire has been designed for the purpose of discovering the reasons behind a child’s lying in the Kindergarten. The researchers have used many statistical means, such as: T-test for one sample and T-test for two independent samples, Pearson correlation coefficient, and Kay square to find the difference between home and kindergarten regarding reasons of lying. Results have shown that the fe(male) children in the kindergarten live in a social environment that lacks honesty; especially the case with male children. Moreover, female kindergarten children enjoy a wide imagination; which is characterized by being exaggerating, abundance,, creativity, and lack of adherence to concrete reality. The reasons to lie for kindergarten male children are higher than that of female’.

As a reusable adsorbent to remove lead from water, a peptide-based magnetic adsorbent incorporating lead-binding peptide was constructed. First, a 7-mer lead-binding peptide (TNTLSNN) was covalently bonded onto the surface of a magnetic bead. Compared to the adsorption capacity of a bare magnetic bead (4.0 mg lead/g bead), the peptide-linked bead exhibited a capacity more than eight times higher than that of a bare bead (34.1 mg lead/g bead). The regenerated peptide bead, by desorbing the lead from the bead with EDTA, could be repeatedly used (tested over six cycles) for the following round of lead adsorption without any significant loss of adsorption capacity. The selective removal of lead in the presence of other interfering metals was demonstrated with the individual or the combinatory use of four metal ions, namely Pb(II), Ni(II), Co(II), and Cu(II), where the amount of adsorbed Pb(II) was remarkably higher than those of the other metal ions. The adsorption isotherm followed the Langmuir model well, with the maximum adsorption loading (qmax) of 70.4 mg lead/g bead.

The presented paper deals with the analysis of selected stress management strategies considering to gender and position in organization in which individual employees work. The aim of the paper is to compare the ways of managing and processing the stressful situations, as well as their variability with regard to the group of respondents, their inclusion in the organization (manager or executive employee) and the size of organization (small and medium organization). The research was conducted by using two methodologies, namely Brief COPE from Carver (1997) and SVF 78 by Janke and Erdmann (2003). The research sample consisted of 130 respondents aged 19 to 63 (mean age 40.38 with a standard deviation of 6.73), namely 53.8% of males and 47.2% of women. The research sample consisted of executive employees (49.2%) and managers (50.8%) working in a small and medium-sized organization. The research results were analyzed by t-test for two independent samples, namely the individual stress management strategies were compared. We found statistically significant differences in the level of control of the situation, self-blaming, POZ 1 and NEG among executive employees and managers. At the level of perseverance, self-blaming, religiosity and spirituality, and NEG we found statistically significant gender differences. Comparison of employees working in a small and medium-sized organization has demonstrated the existence of statistically significant differences in levels of underestimation, negation, ventilation and self-blaming. The most common strategy of stress management was the strategy of self-blaming, given the analyzed socio-demographic characteristics of the respondents.

Maximum Water Content

Tests were made on the water dynamics of water loss in maize at two locations at major maize production areas, Debrecen and Szeged, as a function of the heat sum required up to physiological ripening. The maximum water content was found to vary according to the hybrid and the year. No significant differences were found between the effective heat sums associated with maximum values within a year, the difference being 2-4 calendar days. There was a close correlation between the maximum grain water content and the length of the generative phase for a given hybrid in a given year. Better water supplies (1998) resulted in higher maximum water content values, which indirectly promoted longer and more intensive dry matter incorporation. Of all the environmental parameters, the drying down rate is primarily determined by the temperature. The changes in grain moisture content in a specific hybrid can be characterised by a joint linear graph. The drying down rate of the individual hybrids was determined by examining the b term of the linear equation.

Density functional theory was employed to highlight the antioxidant working mechanism of higenamine in aqueous and lipid-like environments. Different reaction mechanisms were considered for the reaction of higenamine with the •OOH radical. The pH values and the molar fraction at physiological pH were determined in aqueous solution. The results show that the preferred reaction mechanism was the hydrogen atom transfer from the catecholic ring. The computed kinetic constants revealed that, in order to obtain reliable results, it is important to consider all the species present in water solution derived from acid–base equilibria. From the present investigation, it emerges that at physiological pH (7.4), the scavenging activity of higenamine against the •OOH radical is higher than that of Trolox, chosen as a reference antioxidant. Furthermore, higenamine results to be more efficient for that purpose than melatonin and caffeine, whose protective action against oxidative stress is frequently associated with their reactive oxygen species (ROS) scavenging activity.

The composition of aqueous fluoroberyllate solutions has been studied by 9Be and 19F NMR spectroscopy for various ratios of the beryllium and fluorine concentrations, and at different pH values. The equilibrium constants have been determined for the ligand exchange processes, which involve the species [Be(OH2)4]2+, [BeF(OH2)3]+, [BeF2(OH2)2], [BeF3(OH2)]- , and [BeF4]2-. These equilibria are shifted towards [BeF4]2- at high pH. No polynuclear fluoroberyllates have been detected. The fluoride exchange between the individual species is slow on the NMR time scale at room temperature, and separate sharp signals with the expected multiplicity are therefore recorded. Calculated 9Be chemical shifts are in good agreement with experimental data.

Four methods of soil pretreatment for particle-size distribution analyses compared using 10 Saskatchewan soils. Clay percentages, suspension pH values following shaking, and losses due to various treatments were used to evaluate the individual treatments. The high suspension PH required to obtain complete dispersion may not be achieved if excess acid is used to destroy lime carbonates prior to analysis. Lowering soil PH to 5.5 during pretreatment with dilute acid effectively removes free lime carbonates while still allowing complete dispersion.
