It also presents the main categories of use in the studied territory and the measures for the protection and improvement of soils in order to increase their fertility.
Study on the Minimum Workings System and Fuel Consumption Influence
Authors: Moise Virgil 
Published: May 2019

AbstractConservative systems are based on less intense soil loosening, carried out by different methods, without turning the furrow and only in the conditions of keeping a certain amount of vegetal residues at the soil surface; for that reasons are therefore considered to be ecological protection strategies. For this study the parcel of 118.78 ha was divided into two plots of 59.39 ha each. On the first plot (P1) the conventional soil works system was used, while on the second plot (P2) was used the system of minimum soil works. The methodology used was to analyze, synthesize and calculation of fuel consumption. Following the application of soil conservation systems, many benefits have been identified: - the time with soil tillage is reduced at 2-4 times;-the fuel consumption per unit area is reduced by 40-50%;- the number of agricultural machinery at the surface unit is reduced;-soil structure is rebuilt and surface and depth compaction is reduced;- the organic matter content from the soil is increased;- soil permeability for water is increased and global soil drainage is improved;

Magazine Illustrations – Text Accompaniment as Well as Competition
Authors: Dlábková Markéta 
Published: May 2019

Abstract
The article deals with the role of illustrations in pictorial magazines in the second half of the 19th century (Světozor, Zlatá Praha, Květy etc.) and with changes in the image–text relationship. It focuses both on documentary and reportage drawings, which formed a significant part of magazine pictures, and on a magazine presentation of reproductions of works of art and the character of their accompanying commentaries. A closer inspection reveals that, despite the apparent dominance of the visual part, magazines still saw their crucial role in the textual part – which concerned not only the published articles but also the presentation of reproductions. The variation in the interaction between the image and the text is one of the most interesting methods of communication between illustrated magazines and their readers. On specific examples, the article illustrates how magazines worked with their pictorial part in connection with the reproduction techniques available and what meaning and content the reproductions could acquire in relation to the text.
Redox Status, Hematological Parameters as Well Liver and Kidney Function Indicators in Blood of Chickens Receiving Gold Nanoparticles
Authors: Sembratowicz Iwona , Ognik Katarzyna 
Published: May 2019

Abstract
The aim of the study was to assess the biocompatibility of gold nanoparticles (Au-NPs) for chickens by investigating their effect on their growth, hematological parameters, markers of oxidative stress, and indicators of liver and kidney function. The experiment was carried out on 54 chickens assigned to 3 experimental groups of 18 birds each. The control group did not receive gold nanoparticles. The birds in group Au-NPs2.0 received gold nanoparticles in a tube into a crop at a rate of 2.0 mg/kg body weight/day, while the birds in AuNPs5.0 group at a rate of 5.0 mg/kg body weight/day. The blood for analysis was collected after 7, 14, 21 and 28 days of Au-NPs application. The obtained results indicate that short-term (7–14 day) exposure to lower dose (2.0 mg/kg b.w./day) of AuNPs had no toxic impact on chickens, but the extension of the duration time caused toxicological effects evidenced by growth inhibition as well as induction of oxidative stress and liver injury. The higher dose of AuNPs (5.0 mg/kg b.w./day) exerted toxic effects already after 7–14 days of supplementation.
Sensitivity, Impact and Consequences of Changes in Respiratory Rate During Thermoregulation in Livestock – A Review
Authors: Habibu Buhari , Yaqub Lukuman Surakat , Dzenda Tavershima , Kawu Mohammed Umaru 
Published: May 2019

Abstract
This review discusses the thermal conservative and heat dissipating roles of one of the most sensitive thermoregulatory variables (respiratory rate) with the aim of enhancing its application in evaluating both cold and heat adaptation. During cold exposure, livestock enhance the economy of body heat through reduction in respiratory rate with the extent of reduction being greater and commencing at relatively higher ambient temperature in poorly adapted phenotypes. This is accompanied by an increase in tidal volume and alveolar oxygen uptake, but a decrease in partial pressure of oxygen. On the other hand, heat stress induces increase in respiratory rate to enhance evaporative heat loss with the magnitude of such increase being greater and commencing at relatively lower ambient temperature in phenotypes that are poorly-adapted to heat. This is accompanied by a decrease in tidal volume and the development of hypocapnia. The increase in respiratory rate is observed to be greater, moderate and lesser in livestock that are mainly (pigs, rabbits and poultry), moderately (sheep, goats and Bos taurus) and less (Zebu cattle) dependent on respiratory evaporative heat loss, respectively. The changes during chronic heat stress may cause acid-base crisis in all livestock, in addition to reduction in eggshell quality in birds; due to marked decrease in partial pressure of carbon dioxide and a compensatory increase in elimination of bicarbonate. Within and between breed variations in sensitivity of respiratory rhythm to both cold and heat stress has shown high applicability in identifying phenotypes that are more susceptible to thermal stress; with some cellular and metabolic changes occurring to protect the animal from the consequences of hypo- or hyper-thermia. The information in this review may provide basis for identification of genes that support or suppress thermoregulation and may also be of great use in animal breeding, genomics and selective thermal stress mitigation to provide maximum protection and comfort to poorly-adapted phenotypes.

Abstract
Obesity is a serious problem in numerous dog breeds, but knowledge of its hereditary background is scarce. On the contrary, numerous DNA polymorphisms associated with human obesity have been identified, with the strongest effect being demonstrated for FTO gene. We used targeted next-generation sequencing (tNGS) to search for polymorphisms in the region harboring FTO and IRX3 in 32 Labrador dogs. Moreover, we investigated the selected regions of FTO and IRX3, orthologous to the human regions associated with obesity, in 165 Labradors. For all dogs, the following information was available: age, sex, gonadal status, body weight, and body conformation score (BCS). The use of tNGS revealed 12,217 polymorphisms, but none of these obtained significance when lean and obese dogs were compared. Study of two SNPs in the 5’-flanking region of FTO in 165 dogs – creating two upstream reading frames (uORFs) – also showed no association with body weight and BCS but suggested the need for improvement in FTO annotation. No polymorphism was found in the 5’UTR of IRX3. Additionally, no differences of CpG islands methylation status between lean and obese dogs were found. Our study suggests that FTO and IRX3 are not useful markers of obesity in Labrador dogs.

Published: May 2019

Abstract
The main objective of this study was to identify the influences of different climatic conditions and cow-related factors on the respiration rate (RR) of lactating dairy cows. Measurements were performed on 84 lactating Holstein Friesian dairy cows (first to eighth lactation) in Brandenburg, Germany. The RR was measured hourly or twice a day with up to three randomly chosen measurement days per week between 0700 h and 1500 h (GMT + 0100 h) by counting right thoraco-abdominal movements of the cows. Simultaneously with RR measurements, cow body postures (standing vs. lying) were documented. Cows’ milk yield and days in milk were recorded daily. The ambient temperature and relative humidity of the barn were recorded every 5 min to calculate the current temperature-humidity index (THI). The data were analyzed for interactions between THI and cow-related factors (body postures and daily milk yield) on RR using a repeated measurement linear mixed model. There was a significant effect of the interaction between current THI category and body postures on RR. The RRs of cows in lying posture in the THI < 68, 68 ≤ THI < 72 and 72 ≤ THI < 80 categories (37, 46 and 53 breaths per minute (bpm), respectively) were greater than those of standing cows in the same THI categories (30, 38 and 45 bpm, respectively). For each additional kilogram of milk produced daily, an increase of 0.23±0.19 bpm in RR was observed. Including cow-related factors may help to prevent uncertainties of RR in heat stress predictions. In practical application, these factors should be included when predicting RR to evaluate heat stress on dairy farms.

Investigation of the Tribological Behaviors of Upholstery Woven Fabrics after Abrasion
Authors: Akgun Mine 
Published: May 2019

AbstractFabric surface tribology is an important area of study in upholstery fabrics, which is exposed to high friction and abrasion effects. In the studies on the tribology of upholstery fabrics, it is ensured that criteria such as better performance, less degradation, increased usage time, and user comfort are determined and taken into consideration in the woven fabric design. Surface roughness and friction coefficients are important parameters used in determining abrasion, deformation, and wear behaviors of fabrics. In this study, the surface abrasion behaviors of upholstery fabrics woven with basic and jacquard weave patterns and also different structural parameters were investigated in terms of the changes in surface roughness parameters (amplitude parameters: Ra, Rpm, and Rvmand hybrid parameters: Δa) and the changes in surface friction coefficients. These results were also related to the state of the visual changes in the fabrics. Rpm, Rvm, and Δabeing roughness parameters were found to be important in the evaluation of the surface deformation of the fabrics after abrasion besides the Ra parameter. Results showed that the Δaroughness parameter could be suitable for evaluating the deformation of the textile structures to be used, particularly in sensitive applications.

Published: May 2019

Abstract
With time, medical and pharmaceutical research has advanced significantly. However, one of the major issues is how to administer the active substance. Among these, it counts over-or under-dosage of the active substance, low response to treatment, or increased clinical risk of the patient. An innovative method able to avoid these obstacles is represented by controlled release systems for active substances. The interest for these systems came with allowing encapsulation in the antibiotic release matrices, local anesthetics, protein or other substances. Moreover, a number of such vehicles are now available to release controlled substances used predominantly in the anesthesia and intensive care unit.

Abstract

Background. Beta hemolytic streptococcus (BHS) represents a worldwide health problem because of the complications that can occur. Thus, it is important to identify the presence and type of BHS in time to start treatment if needed, avoiding the complications.

Aim. Our aim was to identify the prevalence of Beta Hemolytic Streptococcus in a Children’s Tertiary Care Hospital in Timisoara.

Methods. A cross-sectional study was conducted from April-June 2018 in Emergency Hospital for Children Timisoara. The study lot consists from 1100 children, ages between 0-18 years, which were not given, in the preceding two weeks, any antibiotics. We compared the study with two studies from different cities in Nepal, with the same subject as ours. Group A and Group C Streptococci were identified by beta hemolytic colonies, bacitracin sensitivity, catalase negativity test and latex agglutination test (Oxoid Streptococcal Grouping kit). ASO (Antistreptolysin O) test was also performed from serum samples, for patients with positive cultures. We also tested the antibiotic sensitivity to: Cefepime, Clindamycin, Erythromycin, Tetracycline.

Results. The prevalence of BHS (Beta Hemolytic Streptococcus), especially GABHS (Group A Beta Hemolytic Streptococcus) was 4%, in children from a tertiary care hospital in Timisoara, Romania; which is comparable to the findings of similar studies. In the first study, the prevalence of GABHS was 7.2%, and in the second study was 9%. The patients with positive cultures were also tested for ASO, 28 patients (52%) had high levels, while 26 (48%) had normal levels. On all positive patients an antibiogram was made and we observed that most of the isolates were sensitive to the antibiotics used. A few isolates in Group A were resistant.

Conclusions. Considering the limited data found on our subject, further epidemiological studies on streptococcal disease complex are needed.

Published: May 2019

Abstract
Hemofiltration National Registry is one of the patient registries implemented lately in Romania, currently in use, in response to increased clinical and research needs. The registries of patients with extracorporeal support of vital functions were developed with the support of Romanian Society of Anesthesia and Intensive Care. The registry contains data on over 200 hemofiltration procedures that were per formed in the last 3 years in multiple Romanian hospitals. A sample of data containing records of 2018 was analyzed by K-means clustering, revealing patterns that are potentially useful for healthcare improvement. Among the 6 clusters identified, 3 contain patients with a high mortality rate (90-100%), 1 is defined by intermediate mortality (72%) and 2 by a lower mortality rate (62%). Further research is needed in order to refine the clustering criteria, by using a larger number of cases and potentially examining more outcomes.
Sigmoid growth curves, a new approach to study the dynamics of the epicotyl emergence of oak
Authors: Ukalska Joanna , Jastrzębowski Szymon 
Published: May 2019

Abstract
Three of the most frequently used sigmoidal growth curves from the Richards family are the logistic model, Gompertz model and Richards model. They are used in the analysis of organismal growth over time in many disciplines/studies and were proposed in many parameterisations. Choosing the right parameterisation is not easy. The correct parameterisation of the model should take into account such parameters that are useful to describe the analysed growth phenomenon and are biologically relevant without additional calculations. In addition, each parameter of the model only affects one shape characteristic of each growth curve, which makes it possible to determine standard errors and confidence intervals using statistical software.
Growth curves in germination dynamics studies should provide information on topics such as the length of the lag in onset of germination, the maximum germination rate and, when it occurs, the time at which 50% of seeds will germinate and the final germination proportion. In this article, we present three parameterisations of the logistic, Gompertz and Richards models and indicate two parameterisations for each model, corresponding to the above-mentioned issues. Our proposition is parameterisation by taking into account the maximum absolute growth rate. Parameterisations indicated as useful for germination dynamics are characterised by the fact that each parameter has the same meaning in every model, so its estimates can be compared directly amongst the models. We also discussed the goodness-of-fit measures for nonlinear models and in particular measures of nonlinear behaviour of a model’s individual parameters as well as overall measures of nonlinearity.
All described models were used to study the dynamics of the epicotyl emergence of pedunculate oak. After checking the close-to-linear behaviour of the studied model parameters and by taking into account the criteria of model selection (AICc of each growth curve and the residual variance [RV]), the best model describing the dynamics of epicotyl appearance of pedunculate oak was the Richards curve.

Abstract
Ash dieback caused by an alien, invasive fungus Hymenoscyphus fraxineus is a serious disease of European ash species in many parts in Europe. In Poland, the disease was recorded in the beginning of the 1990s. This study was performed in 2016–2017 with the aim to identify fungi isolated from ash shoots showing dieback symptoms in the Wolica Nature Reserve in Poland, as well as from shoots of two years-old ash seedlings inoculated with H. fraxineus in the greenhouse.
The most frequently isolated fungi from shoots of common ash (associated with the pathogenic fungus H. fraxineus) were identified on the basis of sequencing of the internal transcribed spacer region (ITS1) of fungal rDNA. In total, 19 fungal taxa were identified for ash shoots as follows: H. fraxineus, Fusarium avenaceum, Alternaria spp., Phomopsis oblonga, Diplodia mutila and other Phomopsis spp. The pathogen H. fraxineus was not found for all the shoots samples; one year after inoculation the aforementioned fungi and other species as: Alternaria alternata, Bionectria ochroleuca, Epicoccum nigrum, F. acuminatum, F. avenaceum, and Paraphaesphaeria neglecta were identified in inoculation point, as well as H. fraxineus. The same quantitative and qualitative changes of organisms were observed in the case of artificially colonised ash seedlings in the greenhouse, as well as in the shoots of adult ash trees in the forest.
Metazoan parasites of common sole (Solea solea) and scaldfish (Arnoglossus laterna) (Pleuronectiformes) from Sinop coast of Black Sea
Authors: Güven A. , Öztürk T. 
Published: May 2019

Summary
The metazoan parasites were investigated of two flatfish the common sole, Solea solea (n:140) and the scaldfish, Arnoglossus laterna (n: 22) in the Sinop coast of Black Sea from June 2015 to June 2017. A total of 15 metazoan parasite species belonging to Digenea (6), Cestoda (3), Acanthocephala (1), Nematoda (4) and Isopoda (1) taxonomic groups were identified. Solea solea was found to be infected by Condylocotyla pilodora, Proctoeces maculatus, Opecoelidae gen. sp., Metadena sp., Stephanostomum sp., Progrillotia sp., Capillaria gracilis, Cucullanus campanae, Solearhynchus rhytidotes and Nerocila orbignyi. Arnoglossus laterna was found to be infected by Lecithochirium musculus and Grillotia erinaceus. Scolex pleuronectis, Hysterothylacium aduncum and Dichelyne minutus were determined in both flatfish. Infection prevalence and mean intensity values were re- corded for each parasite species. Infection values for each parasite species in relation to season and fish size were also determined and compared as comparatively. This study is the first one assessing the metazoan parasites both of S. solea and A. laterna collected from the Turkish coast of Black Sea. While Condylocotyle pilodora and Capillaria gracilis are new parasite records for S. solea, Grillotia erinecaus is new parasite record for A. laterna. Moreover, this paper is the first report on occurrence of Opecoelidae gen. sp., Metadena and Stephanostomum genera in S. solea.
