Computed tomographic and densitometric analysis of tibiotarsal bone mineral density and content in postnatal peking ducks (Anas platyrhynchos var. domestica) as influenced by age and sex
Authors: Charuta A. , Cooper R.G. 
Published: May 2018

Abstract
The bone mineral density BMD and content BMC were analysed in the tibiotarsal bones of ducks in the postnatal development as influenced by age and sex. One hundred birds from the nesting till the slaughtering maturity were included in the experiment. The analysis was conducted using a densitometer, Norland - Excell Plus and pQCT computed tomography, XCT Research SA Plus.
The statistical analysis was conducted using the Kruskal-Wallis one-way analysis of variance (age) and the U-Mann -Withney test (sex). All calculations were performed in Statistica 9.0 (StatSoft, Inc. Tulsa, USA), at P ≤ 0.05. Two-factor analysis of variance ANOVA was applied and Pearson’s correlation coefficients were calculated.
The densitometer research showed that BMD and BMC increased in the postnatal development for both sexes. The volumetric bone mineral density vBMD analysis using computed tomography showed that volumetric bone mineral density vBMD of the middle of the diaphyses in situ gradually attenuated during the postnatal development both in males and females, i.e. from 620 mg/cm3 (2 wk) to 500 mg/cm3 (8 wk). The biggest vBMD loss was observed in the diaphyses of females in 4 and 6 wk (r = - 0.63 and r = - 0.79; P ≥ 0.05).
The BMC decrease was observed in the proximal metaphyses between 4 and 6 wk for both sexes, r = - 0.52 (males), r = - 0.53 (females); P ≤ 0.05. The gradual loss may be the cause of deformities and fractures of the tibiotarsal bones observed from 4 wk in particular bone sections of both sexes. The achieved results may constitute a helpful source of information for water poultry breeders to prevent limb diseases.

Some aspects of dimeric metylsalicylatocopper(II) complexes preparation
Authors: Puchoňová Miroslava , Švorec Jozef , Valigura Dušan 
Published: May 2018

Abstract
A systematic study of the preparation of methylsalicylatocopper(II) complexes with or without N-donor ligand has resulted in three new dimeric complexes formation. The investigation has been targeted to two main aspects: the conditions of dimeric complexes preparation and the properties of obtained products. The common stoichiometric formula for all three complexes is Cu(x-MeSal)2(H2O)(ACN)z (where x-MeSal = 3- or 4-methylsalicylate anion, ACN = acetonitrile and z = 0, 1). Used spectral measurements mainly EPR spectroscopy gave the proof about the existence of dimeric “paddle-wheel” units in all three complexes. Moreover, it was concluded that acetonitrile molecules are more probably bonded to copper(II) atoms in apical positions of dimeric units. The water molecules are in coordination sphere only in the case when acetonitrile is not present. However data show that presence of 4-methylsalicylate anions led to strengthening of Cu-N bonds.

External water exchange of lakes as the integral indicator of water body types
Authors: Doganovsky Arkady M. 
Published: May 2018

Abstract
External water exchange of overflow lakes is presented as the integral indicator, defining the type of lake basin. Intensity of water replacement in the lake (Kw) determines many processes taking place in the lake and its drainage area. Simultaneously this process influences the runoff of the outflowing river. Among the processes in the lake, depending on Kw, transitory-accumulative possibilities, predominance of allochton and limnic processes, and the participation of Kw in forming trophic status are considered. Some examples of the dependence of the parameters of lake level distribution curves upon the Kw values are given. The problem of calculation of Kw for unexplored objects is also regarded. The text contains specific examples of the results of calculations and analysis.

The Recent View on the Obstructive Sleep Apnoea Syndrome in Children – Short Résumé
Authors: Sujanska A , Durdik P , Banovcin P 
Published: May 2018

Abstract
The authors present a recent overview of the common clinical manifestations, management, diagnostic criteria and currently accepted treatment approaches of children with obstructive sleep apnoea syndrome (OSAS). Paediatric OSAS has become widely recognized as a frequent disorder and as a major public health problem. Diagnosis of this problem is usually based on physical examination, history and clinical evaluation confirmed by the polysomnography (PSG). PSG is considering as a gold-standard test for establishing the presence and severity of sleep disordered breathing (SDB) in children. According to current understanding, OSAS is a dynamic process in which increased upper airway collapsibility is present resulting from a combination of structural and neuromotor abnormalities, rather than from structural abnormalities alone. In children the OSAS has completely different clinical features and requires different management strategy. Snoring, difficult breathing and apnoea during sleep, restless sleep, frequent awakening and behavioural disturbances are the typical symptoms usually present in children with OSAS. Nowadays, the classic presentation of child with OSAS as underweight child with adenotonsillar hypertrophy is being replaced by younger overweight or obese patients usually without the hypertrophied adenoids and tonsils. Recently it has been reported that delayed diagnosis of OSAS can lead to neurobehavioural consequences and even serious cardiorespiratory morbidity, metabolic complications, as well as an increase in insulin resistance, high blood pressure and the development of OSAS in adulthood. OSAS must be diagnosed and managed aggressively with having these new repercussions. Evidence suggests that the surgical intervention with removal of the tonsils and/or adenoids will lead to significant improvements in the most incomplicated cases, as recently reported from a meta-analysis. SDB and especially OSAS should be taken into serious consideration by pediatricians to prevent comorbidities in adulthood.

Published: May 2018

Abstract
Attention-deficit/hyperactivity disorder (ADHD) in childhood or adolescence is associated with a significantly higher lifetime risk of oppositional defiant disorder, anxiety disorder, conduct disorder, among others. Reports of co-morbidity rates are variable and influenced by assesment methodology and refferal bias, and may reflect lifetime rates within clinical groups. Up-to date studies revealed that as many as 85% of patients with ADHD have at least one psychiatric comorbidity and approximately 60% have at least two. Research and clinical practice has shown that having multiple co-existing psychiatric problems increase the severity of ADHD and behavioural problems, and is associated with incereased psychosocial impairment. The high rate of psychiatric problems co-occuring with ADHD has strong implications for the management of these patients. The presence of co-existing psychiatric conditions may moderate the response to treatment of ADHD and ADHD treatments may adversely affect and exacerbate the symptoms of the co-morbit condition. The aim of this article was to summarize the use of atomoxetine in the most frequent co-morbid disorders accompaining ADHD, ODD (oppositional defiant disorder) and anxiety, and to emphazise decrease of co-morbid symptoms with treatment of atomoxetine what exhort us to think about them as about possible subtypes of ADHD.
Photocatalysis in the treatment and disinfection of water. Part I. Theoretical backgrounds / Fotokataliza w oczyszczaniu i dezynfekcji wody część i. podstawy teoretyczne
Authors: Bodzek Michał , Rajca Mariola 
Published: May 2018

Abstract
Photocatalysis process belongs to an advanced oxidation technology for the removal of persistent organic compounds and microorganisms from water. It is the technology with a great potential, a low-cost, environmental friendly and sustainable treatment technology to align with the “zero” waste scheme in the water/wastewater industry. At present, the main technical barriers that impede its full commercialization remained on the post-recovery of the catalyst particles after water treatment. This paper reviews the background of the process and photooxidation mechanisms of the organic pollutants and microorganisms. The review of the latest progresses of engineered-photocatalysts, photo-reactor systems, and the kinetics and modeling associated with the photocatalytic and photodisinfection water and wastewater treatment process, has been presented. A number of potential and commercial photocatalytic reactor configurations are discussed, in particular the photocatalytic membrane reactors. The effects of key photo-reactor operation parameters and water quality on the photoprocess performances in terms of the mineralization and disinfection are assessed.
Removal of arsenic compounds with peat, peat-based and synthetic sorbents / Usuwania związków arsenu za pomocą torfu, sorbentów na bazie torfu i sorbentów syntetycznych
Authors: Ansone Linda , Eglite Linda , Klavins Maris 
Published: May 2018

Abstract
Arsenic contamination of waters is a global problem; therefore, new approaches for its removal are needed. Peat, peat modified with iron compounds, iron humates and polymeric cation exchangers modified with iron were prepared and tested for sorption of arsenic compounds in comparison with weakly basic anionites. The highest sorption capacity was observed when peat sorbents modified with iron compounds were used. Sorption of different arsenic speciation forms onto iron-modified peat sorbents was investigated as a function of pH and temperature. It was established that sorption capacity increases with a rise in temperature, and the calculation of sorption process thermodynamic parameters indicates the spontaneity of sorption process and its endothermic nature.
Concentration of polycyclic aromatic hydrocarbons in Hypogymnia Physodes (L.)Nyl. thalli and changes to morphological structure / Kumulacja wielopierścieniowych węglowodorów aromatycznych w plechach Hypogymnia physodes (L.)Nyl. i zmiany w ich budowie morfologicznej

Published: May 2018

Abstract
Apart from widely known anthropogenic pollutants as SO2, NOx, CO2, CO, there are another dangerous substances emitted to the air named polycyclic aromatic hydrocarbons (PAH). In the air they occur in a form of vapours and aerosols deposited on dust particles of 10 μm (PM 10) and 2.5 μm (PM 2.5) in diameter. In cities, the air polluted by gases and atmospheric particulate was analysed using special automatic or semi-automatic equipment or analytic procedures. That is why a powerful development of bioanalytical techniques based on using organisms as bioindicators is observed in recent years. The lichens are the most frequently used organisms in bioindication. The purpose of this research is to evaluate air pollution by PAHs in urban agglomeration with the use of Hypogymnia physodes (L.)Nyl. The research was performed in two hundred thousand occupants in south-east Poland in 2004-2007. The lichens placed on tree branches of 30 cm on 4 crossroads, and the 3 branches were put in each research point. Before starting the exposition, the “O” sample had been collected that had been stored in a closed container before chemical analysis. The exposition period lasted for 3 months. Then PAHs were determined in collected lichens. The analysis was performed with high performance liquid chromatography (HPLC), LiChrosper (TM) column 100 RP - 18, UV detector; λ = 254 nm. The concentration was expressed in mg/kg of dry mass that is after deducting PAH value determined in “O” sample. The analysis of obtained results showed diverse concentration of the pollution in the analysed crossroads depending on the road traffic density and season. PAH concentrations were determined from 0.61 mg·kg-1 d.m. in the 1st quarter of 2004 to 2.56 mg·kg-1 d.m. in the 1st quarter of 2006, and from 0.48 mg·kg-1 d.m. in the 4th quarter of 2004 to 2.22 mg·kg-1 d.m. in the 4th quarter of 2006. Meteorological conditions influence the concentration of PAHs in lichens. The atmospheric precipitation contributed to the decrease of PAHs concentration in the air by scavenging the pollution with atmospheric particulate. The regression line amounted to y = 1.91759 - 0.00674 · x, at the confidence interval equal to p = 0.0308. A relation between the PAH concentration and air relative humidity turned out to be the most essential correlation. This relation indicates that the concentration of PAHs in the lichens increases with an increase of humidity. The line regression amounted to y = -1.04196 + 0.02897 · x, at the confidence interval equal to p = 0.0505.

Abstract
The Srebarna Lake Biosphere Reserve is a protected natural site of national and international significance. It characterizes with extremely high biodiversity, being one of the last wetlands along the Lower Danube preserved in relatively natural state; the lake area is NATURA 2000 site. This study was designed to further research on the impact of intensive agriculture on the lake’s ecological status. First task was to find an evidence for link between intensive agriculture and the loading of the lake with nutrients. The second was a study on the PAH’s penetration into the lake ecosystem. An overview was made on drinking water data for 2 underground (drinking water springs). Dyakova spring’s water displayed good ecological state after measured parameters PO3-4 , NO2-3, NO- 2 and pH. Todorankina spring did not fell within the boundaries of good and very good conditions. Increased nitrate levels in water samples leads us to conclude that agriculture in this part of the surrounding area affect groundwater quality in the biosphere reserve. Results from GC-MS analysis proved, that there is no groundwater contamination, responsible for the existing (although low) concentrations of PAH found in the lake.
Influence of Wind on Air Movement in a Free-Stall Barn During the Summer Period / Wpływ wiatru na ruch powietrza w oborze wolnostanowiskowej w okresie letnim
Authors: Herbut Piotr , Angrecka Sabina , Nawalany Grzegorz 
Published: May 2018

Abstract
Use of natural ventilation in the barn should lead to optimal microclimatic conditions over the entire space. In the summer, especially during hot weather, higher air velocity cools cows, which helps to avoid heat stress. The paper presents the results of studies on the evolution of air movement in a modernized free-stall barn of the Fermbet type with the natural ventilation system during the summer period. Based on measurements of velocity and direction of air flow (inside and outside the barn) and observations of smoke indicator, the movement of air masses in different parts of the barn was identified. Significant variations of air flow at different levels of the barn were found. These differences deviate from the accepted patterns of natural ventilation, which can be found in the literature. The range of a draught and stagnant air along with the conditions in which they are built was determined. On this basis, recommendations regarding the location of barns on the plots and the improvement of ventilation in summer were made.
The Effect of Carcass Conformation Class (Europ System) on the Slaughter Quality of Young Crossbred Beef Bulls and Holstein-Friesians / Porównanie wartości rzeźnej buhajków mieszańców mięsnych i holsztyno-fryzów w zależności od klasy uformowania w systemie EUROP

Abstract
The objective of this study was to determine the effect of genotype and carcass conformation class on the slaughter quality of 200 young bulls, including 108 crossbred beef bulls and 92 Holstein- Friesians (HF), aged 21-22 months, selected in the lairage. The lean meat content was estimated and body measurements were taken before slaughter. After slaughter, the carcasses were graded according to the EUROP system, and carcass quality parameters were determined. Intramuscular fat was extracted from samples of m. longissimus dorsi, and the fatty acid profile of extracted fat was determined by gas chromatography. 61.11% carcasses of crossbred beef bulls were graded in the conformation class R, and 56.53% carcasses of Holstein-Friesians were classified as O. The majority of carcasses belonged to fat class 2, which was not consistent with intramuscular fat content. Within the same conformation classes, crossbred beef bulls were characterized by higher slaughter quality than Holstein-Friesian bulls. Meat from hybrid beef bulls had a higher (by 0.42% on average) content of fat with a more desirable composition. Since the population size of beef cattle will probably not increase in the nearest future, efforts should be continued to optimize the production of high-quality beef from dairy cattle herds.
