Published: October 2017

ABSTRACTInternal pressures change throughout a cetacean's body during swimming or diving, and uneven pressures between the thoracic and abdominal compartments can affect the cardiovascular system. Pressure differentials could arise from ventral compression on each fluke downstroke or by a faster equilibration of the abdominal compartment with changing ambient ocean pressures compared with the thoracic compartment. If significant pressure differentials do develop, we would expect the morphology of the diaphragm to adapt to its in vivo loading. Here, we tested the hypothesis that significant pressure differentials develop between the thoracic and abdominal cavities in diving cetaceans by examining diaphragms from several cetacean and pinniped species. We found that: (1) regions of cetacean diaphragms possess subserosal collagen fibres that would stabilize the diaphragm against craniocaudal stretch; (2) subserosal collagen covers 5–60% of the thoracic diaphragm surface, and area correlates strongly with published values for swimming speed of each cetacean species (P&lt;0.001); and (3) pinnipeds, which do not locomote by vertical fluking, do not possess this subserosal collagen. These results strongly suggest that this collagen is associated with loads experienced during a dive, and they support the hypothesis that diving cetaceans experience periods during which abdominal pressures significantly exceed thoracic pressures. Our results are consistent with the generation of pressure differentials by fluking and by different compartmental equilibration rates. Pressure differentials during diving would affect venous and arterial perfusion and alter transmural pressures in abdominal arteries.

Ionocidium ‘Cerrado 101’: intergeneric orchid hybrid with high quality of blooming
Authors: Cardoso Jean Carlos 
Published: October 2017

Orchids are considered one of the most important potted-flowering in the world. Oncidium genus, as well their hybrids group (OHGs) has used for the flower market as pot or cut flower. However, some horticultural characteristics require improvements, e.g. the production of precocious cultivars, independent-season blooming or easy flowering induction, high quality and durability of flowers and variations in color of flowers, to compete with Phalaenopsis and Dendrobium orchids, as other flower groups. Aiming this purpose there were used hand-crossing pollination between the Oncidium ‘Sweet Sugar’ and Ionopsis utricularioides, a Brazilian wild species, for evaluate the capacity of crossing and to select progenies with interest of use in floriculture as new cultivar. The seeds obtained from this cross were seeded on in vitro conditions, followed by acclimatization and cultivation on greenhouse conditions until de flowering time. One of the plants obtained presented interesting characteristics, as good and rapid vegetative development and high quality of blooming. This hybrid obtained from an intergeneric crossing resulted in a plant with vegetative and flower type characteristics and color similar of Oncidium female parent, but with larger number of ramifications in inflorescence and number of flowers (60% and 219,4%, respectively) than Oncidium parent (♀), and with more similarity with Ionopsis (♂). This hybrid cultivar, called Ionocidium ‘Cerrado 101’ is one more option of OHGs in this competitive market and can be used either for pot and also for cut orchid flowers production, main because it longer inflorescence (83 cm).
Endothelial dysfunction in experimental models of metabolic syndrome − effect of fructose

Published: October 2017

Abstract
The aim of the work was to find an experimental model suitable for the study of endothelial dysfunction induced by MS. We used hypertriglyceridemic rats (HTG) that were fed a hypercholesterolemic diet of different composition and duration: a 6-week administration of standard diet with an addition of cholesterol and fat (HTGChol) and a three-month administration of the same diet with an addition of fructose (HTGCholF). We investigated the effect of different diets on aortic endothelial function. The standard diet fed Wistar (W) and HTG rats served as controls. Decision for addition of fructose to HTGChol was done based on in vitro experiments evaluating the effect of high concentration of saccharide in the incubation solution on aortic endothelial function. This intervention caused significant deterioration of relaxation induced by acetylcholine (ACh). While in HTGChol, we did not find significant differences in the function of the aorta compared to W or HTG rats, adding of fructose to high fat diet and prolonging its administration resulted in significantly impaired endothelium-dependent relaxation. It seems that such a model is suitable for the study of endothelial dysfunction in MS and the effect of substances that may protect the endothelium.
Isolated pliosaurid teeth from the Albian–Cenomanian (Cretaceous) of Annopol, Poland
Authors: Madzia Daniel , Machalski Marcin 
Published: October 2017

AbstractBrachauchenine pliosaurids were a cosmopolitan clade of macropredatory plesiosaurs that are considered to represent the only pliosaurid lineage that survived the faunal turnover of marine amniotes during the Jurassic- Cretaceous transition. However, the European record of the Early to early Late Cretaceous brachauchenines is largely limited to isolated tooth crowns, most of which have been attributed to the classic Cretaceous taxon Polyptychodon. Nevertheless, the original material of P. interruptus, the type species of Polyptychodon, was recently reappraised and found undiagnostic. Here, we describe a collection of twelve pliosaurid teeth from the upper Albian-middle Cenomanian interval of the condensed, phosphorite-bearing Cretaceous succession at Annopol, Poland. Eleven of the studied tooth crowns, from the Albian and Cenomanian strata, fall within the range of the morphological variability observed in the original material of P. interruptus from the Cretaceous of England. One tooth crown from the middle Cenomanian is characterized by a gently subtrihedral cross-section. Similar morphology has so far been described only for pliosaurid teeth from the Late Jurassic and Early Cretaceous. Even though it remains impossible to precisely settle the taxonomic distinctions, the studied material is considered to be taxonomically heterogeneous.
Is the burnout syndrome associated with elder mistreatment in nursing homes: results of a cross-sectional study among nurses

Published: October 2017

Abstract
As this issue has not yet been addressed in Croatia, our aim was to explore the presence of the burnout syndrome in nurses and see how it is related to their perception of elder mistreatment in nursing homes and extended care units. The burnout syndrome was assessed in 171 nursing professionals with a standardised Maslach Burnout Inventory for Human Services Survey (MBI-HSS) for three dimensions: emotional exhaustion (EE), depersonalisation (DP), and personal accomplishment (PA). High EE was reported by 43.9 %, high DP by 22.2 %, and low PA by 39.8 % of the respondents. Their perception of elder abuse and neglect was investigated with two self-completion questionnaires. The answers suggest that elder mistreatment in Croatian nursing homes and extended care units is more common than expected: 55 % witnessed shouting at a resident in anger, 43 % insulting and swearing at a resident, 42 % force-feeding the resident, 39 % ignoring a resident when they called, and 38 % neglecting to turn or move a resident to prevent pressure sores. We also established associations between a number of questionnaire items on perceived abuse and neglect and the burnout syndrome dimensions and determined the items that predicted the type and level of burnout in our respondents. One way to avoid the pitfalls that lead to abuse and neglect is education in schools and at work. We believe our research could contribute to this end.
Accumulation of heavy metals from soil in medicinal plants

Published: October 2017

AbstractMedicinal plants accumulate heavy metals from contaminated soil, and their consumption can cause poisoning. Our objective was to determine the levels of Pb, Cd, Zn, Cu, Fe, and Mn in four medicinal plant species (Achillea millefolium, Hypericum perforatum, Plantago lanceolata, and Urtica dioica) and their native soil, all sampled at a former smelter. The highest soil Cd, Pb, and Zn levels surpassed the maximum allowed limit 75-fold, 48-fold, and 14-fold, respectively. Their soil levels correlated with those in the plants, but this was not the case with Cu, Fe, and Mn. Heavy metal accumulation seems to depend on the plant species, yet even so, medicinal herbs should be cultivated and gathered only from controlled (uncontaminated) areas. Polluted areas should be monitored on a regular basis, while further research should investigate the connection between the heavy metal levels in the soil, their levels available for plants, and the levels extractable from plants.
Hanuš Jelínek’s Beginnings in Mercure de France
Authors: Servant Catherine 
Published: October 2017

Abstract
The aim of this article is to describe the beginnings of the cooperation between Hanuš Jelínek and the journal and publishing house Mercure de France. In March 1900, Jelínek published, under the pseudonym Jean Otokar, his first study ‘La Poésie moderne tchèque’ in the Parisian journal. For some time, the critic then wrote the column ‘Lettres tchèques’ (August 1900 – February 1903) in Mercure – after Alexandr Bačkovský (alias Jean Rowalski) and before William Ritter. The early origin of the ‘Lettres tchèques’ of Bačkovský and Jelínek as a result of the aesthetic affinity between literary and artistic modernism on the one hand and some French and Francophone circles of the time on the other has the merit of introducing the readers of an important French periodical to Czech production. These columns have their firm place in the history of Czech efforts to gain recognition in France and the French-speaking world.

The Effects of Trunk Cavity and Air-Gaps in the Acoustic Response of a Passenger Vehicle
Authors: Oktav Akın 
Published: October 2017

AbstractThe effects of additional cavities and air-gaps in the acoustic response of a passenger vehicle are investigated. It is observed that the cabin cavity and the trunk cavity of the passenger vehicle are connected through an aperture in the rear seat. In the trunk cavity of the vehicle, there are two more air-gaps which are designed as countermeasures to trunk lid slam noise. It is established that acoustic modes and acoustic eigenfrequencies of the vehicle are altered through the trunk cavity and its air-gaps. To develop an analytical solution, the actual acoustic cavity is simplified into a rectangular shape. In the analytical solution, the coupling of trunk and cabin cavities is considered. It is shown that the computational analysis results match well with the results of the analytical solution proposed. Further, the resonator effect of air-gaps present in the trunk cavity is examined.

Authors: Kukulski Bartłomiej , Wszołek Tadeusz 
Published: October 2017

Abstract
This paper presents the result of research on the impulsive components of a railway noise generated during passage through a railroad switch compared with a typical rail noise and evaluation of this phenomenon with particular emphasis on impulsive sounds. The study includes the analysis of the source of impulsive components in the railway noise, the methodology of measurement and data analysis. Spectral analysis of typical fragments passing through a railroad switch is given together with a proposal of additional indicators to assess the noise. Authors propose three descriptors of the impulsive noise such as spectral centroid, kurtosis and impulsiveness, and show that these descriptors can be useful in assessment of the impulsive noise generated during trains’ crossing.
Frequency Analysis of Noise Generated by Pneumatic Wheels

Published: October 2017

AbstractThe dominant sources of traffic noise, which are linked directly to the vehicle, are dependent on the speed. In terms of speed of 50-120 km/h the dominant source of noise is pneumatic wheels. The aim of the research was chosen to develop a method and experimental determination of the dominant frequency components of noise generated by the car tire. For the purpose of the study and on the basis of the analysis of the source data it was assumed that there is a relationship between the vibration of the tread elements and emitted noise, especially for low and medium frequencies. Thus, the target was set on the basis of the own method of research in the built measuring station. Based on the survey and the obtained results it can be stated that in the spectrum of the noise emitted by the tires the frequency components are dominant. Non-directional tire structure includes more frequency components which at the speed adopted in the studies are located at a greater frequency range than it is for the directional tire. In the case of a tire with a directional tread, acoustic emission energy is more associated with specific frequency components. The developed method provides results independent from the influence of the type of road surface on the acoustic emission while driving.
Transition Time of Ultrasonic Wave as a Tool of Quality Evaluation of Layered Polymer Composites
Authors: Szymiczek Małgorzata 
Published: October 2017

AbstractObservation of behaviour phenomena of ultrasonic waves in an object allows for quality assessment, identification and location of discontinuity. Physical nature of acoustic processes is based on propagation of mechanical waves constituting a disturbance of equilibrium of the state of material. The acoustic process identified by selected characteristics can be a source of information about state of material, its structure, and properties, which is particularly important for systems exhibiting anisotropy properties, and such are layered polymer composites. They are special materials because their properties depend greatly on the manufacturing technology. Therefore, while conducting acoustic tests which use the influence of elastic properties and homogeneity of material structure for propagation of sound waves the adopted method of measuring characteristics which identifies propagation of ultrasonic wave phenomenon is of particular importance. The aim of the work was quality evaluation of layered polymer composites made by winding and press moulding by the method of echo and C-scan, using head Phased Array. Composites have been tested by thermal and fatigue degradation. Quality evaluation has been made based on the transition time of the ultrasonic wave and the bending strength.

Published: October 2017

AbstractOne of the most important problems with regard to the Surface Acoustic Wave (SAW) gas sensors technology is the deposition of chemosensitive films exhibiting desirable chemical and physical properties. The electrospraying technology seems to be a very promising method of the film deposition in this case. It allows the chemosensitive layers to be obtained out of almost any chemicals and their mixtures in a controllable way. The process gives the possibility to generate specific films with properties unattainable if other methods were to be applied. For example, it allows to deposit solutions of polymers and suspensions of solids in polymer solutions which can degrade in the process of thermal evaporation deposition. The paper describes the results of experiments with electrospraying technique in order to obtain Nafion® films. The influence of the process parameters on film sensitivity has been studied.
Brain Drain Migration from Romanian Academia. The End of a Mirage
Authors: Panzaru Ciprian , Reisz Robert D. 
Published: October 2017

Abstract
The article is focused on the image of migration that Romanian academics transmit through the invisible curricula of the universities. These opinions are bound to become vectors of the future behaviour of graduates and legitimate a certain approach to brain drain. The goal of the research was to find how opinions and intentions on migration changed between 2000 and 2013 and what possible explanations can be found for these changes. The analysed data were collected in two sample surveys, one conducted in 2000 and another one in 2013. The results clearly show that there is an impressive change in the interest of Romanian academics to emigrate. Information and personal experience on migration and international mobility have become pervasive in the higher education system. Migration as a mirage, as a temptation not fully understood, does not exist anymore in Romanian higher education.

Published: October 2017

AbstractBackground:The palmaris longus muscle is one of the most variable muscles in the human body and there have been numerous variations reported. The different palmaris longus variations are interesting not only from an anatomical point of view, but they could also have definite clinical significance.Aim:The aim of this study was to examine the different types of variations of palmaris longus muscle in the Bulgarian population.Materials and methods:Over a period of 15 years, 56 formol–carbol fixed human cadavers were studied to investigate the different variations of palmaris longus muscle (PLM).Results:Various anatomical variations of PLM have been reported: absence (2.68%); reversed palmaris longus coexisting with an additional abductor digiti minimi muscle (0.89%); digastric (0.89%); palmaris longus with intermediate muscle belly (1.79%) and duplication (1.79%).Conclusions:To reveal the wide variety of the types of palmaris longus muscle and their importance for clinical practice, we make a brief literature review concerning the different types of variations, their role in the median and ulnar neuropathy in the wrist or as structures simulating a soft tissue tumour and the application of palmaris longus tendon in plastic and reconstructive surgery as grafting material. We also present new systematic anatomical and clinical classifications of palmaris longus variations by dividing them into two simple groups.

Published: October 2017

AbstractBackground:Pharmacological treatment of depression is currently led by the trial and error principle mainly because of lack of reliable biomarkers. Earlier findings suggest that baseline alpha power and asymmetry could differentiate between responders and non-responders to specific antidepressants.Aim:The current study investigated quantitative electroencephalographic (QEEG) measures before and early in treatment as potential response predictors to various antidepressants in a naturalistic sample of depressed patients. We were aiming at developing markers for early prediction of treatment response based on different QEEG measures.Materials and methods:EEG data from 25 depressed subjects were acquired at baseline and after one week of treatment. Mean and total alpha powers were calculated at eight electrode sites F3, F4, C3, C4, P3, P4, O1, O2. Response to treatment was defined as 50% decrease in MADRS score at week 4.Results:Mean P3 alpha predicted response with sensitivity and specificity of 80%, positive and negative predictive values of 92.31% and 71.43%, respectively. The combined model of response prediction using mean baseline P3 alpha and mean week 1 C4 alpha values correctly identified 80% of the cases with sensitivity of 84.62%, and specificity of 71.43%.Conclusions:Simple QEEG measures (alpha power) acquired before initiation of antidepressant treatment could be useful in outcome prediction with an overall accuracy of about 80%. These findings add to the growing body of evidence that alpha power might be developed as a reliable biomarker for the prediction of antidepressant response.
