Authors: Kobetičová Hana , Lipovský Marek , Wachter Igor , Soldán Maroš 
Published: September 2015

Abstract
The main objective of this paper is to evaluate the efficiency of 3,5-dichlorophenol removal from wastewater by using alternative low cost adsorbents. Waste from the production and processing of metals (black nickel mud, red mud) and a biosorbent (Lemna minor) were used for this research. Initial concentration of the contaminant was 4 mmol L−1, the contact time of sorbent and waste water was 0 - 48 hrs and the temperature during experiment was 25 ± 0.2 °C. The results show that the highest removal efficiency of 3,5 - dichlorophenol (58.18 %) was reached by the red mud in 48 hours.

Authors: Sirotiak Maroš , Lipovský Marek , Bartošová Alica 
Published: September 2015

Abstract
In the research described in this paper, studied was sorption capacity of natural and ferric modification of zeolite tuff containing mineral clinoptilolite from the Nižný Hrabovec deposit to remove potentially toxic metals (ionic forms of chromium, nickel, copper and aluminium) from their water solutions. We reported that the Fe (III) zeolite has an enhanced ability to sorption of Cu (II), and a slight improvement occurs in the case of Cr (VI) and Ni (II). On the other hand, the deterioration was observed in the case of Al (III) adsorption.

Authors: Gerulová Kristína , Tatarka Ondrej , Štefko Tomáš , Škulavík Tomáš 
Published: September 2015

Abstract
The increase in mineralization and biodegradability of MWFs by ozone/ultraviolet in comparison with ozone were investigated. Studied were two similar synthetic fluids pre-treated by the combination of the O3/UV advanced oxidative method. Expectations that the pre-treatment could enhance biodegradability of the metalworking fluid were not confirmed. The combined oxidation process at the defined conditions resulted in 1-35 % decrease of the achieved primary degradation level. Samples were prepared from real concentrates and diluted to approximately 350 mg/L of TOC.

Authors: Poliaková Adela 
Published: September 2015

Abstract
The Fault Tree process utilizes logic diagrams to portray and analyse potentially hazardous events. Three basic symbols (logic gates) are adequate for diagramming any fault tree. However, additional recently developed symbols can be used to reduce the time and effort required for analysis. A fault tree is a graphical representation of the relationship between certain specific events and the ultimate undesired event (2). This paper deals to method of Fault Tree Analysis basic description and provides a practical view on possibility of application by quality improvement in road freight transport company.

The Analysis of Early Maladaptive Schemas which Facilitate High Performance in Women Handball and Rugby Players
Authors: Gherghişan Alina-Isabela 
Published: September 2015

Abstract
Starting with the assumption of the interdependence between psyche and soma and considering the idea that performance is rooted in the history of each athlete as a unique individual, but also in the collective history of the team to which the athlete belongs, the present study aims to identify those elements in terms of early maladaptive schemas, part of each player’s personal history that stimulates a “repair and healing game” at group level, with reference to the specific sport practiced, leading to high-level athletic performance. In order to meet the objectives of the study we used the psychological instrument YSQ (Young’s Schemas Questionnaire) as individual assessment tool. Existing data were obtained from the components of two national teams, women, senior level, the national rugby 7s team, and the national handball team. There were tested two hypotheses, specifically: (1) There is a common spectrum of early maladaptive schemas for the rugby and handball players considering the similarities between the two sports; (2) There are significant differences in which it concerns early maladaptive schemas between the rugby players and the handball players, considering the specific of each sport. Both hypotheses of the study confirm, the results outlining an interesting dynamic in both sports considered.
Effects of Altering the Number of Players and the Dimensions of the Playing Area on the Possession Characteristics in Youth Australian Football
Authors: Pill Shane , Elliott Sam 
Published: September 2015

Abstract
This research compared the effects of altering the number of players and the dimensions of the playing area on the possession characteristics in youth (under-14) Australian football. A modified ‘small sided game’ (SSG) 12-a-side version was compared to the full field ‘adult’ 18-a-side game. Games were video recorded and the possession characteristics later coded using the Dartfish Easy Tag program. It was found that the additional players in the 18-a-side version led on average to more tagged events (technical actions) per 18 minute period of play; however, there was a decrease in the number of tagged events per player. It was also observed that there were more scoring actions in the SSG 12-a-side game play than in the 18-a-side. The SSG 12-a-side version provided more technical actions per player in each play period and so it is suggested that it constructs a better educational experience, and therefore game development, than the 18-a-side game recommended for Australian football from under-11.
Species Composition of the Benthic Macroinvertebrates on the Coastline Vegetated Rocky Substrates of the Southern Caspian Sea
Authors: Ghasemi Amir Faraz 
Published: September 2015

Abstract
For studying benthic macrofaunal composition associated with seagrass rocky beds of the southern Caspian Sea, two time samplings were carried out along the coast line in the winter and summer of 2013. In total, 1,286 specimens of the five species were identified: Pontogammarus maeoticus, Balanus improvisus, Mytilaster lineatus, Palaemon elegans and Alitta succinea. The total recorded abundance was 5,675 and 755 ind./m2, with a biomass of 147,271 and 31,238 mg/m2 in the winter and summer respectively. The collected species in this study are generally non-indigenous (except P. maeoticus) and could potentially have an effect on native benthic fauna, as an additional food source could facilitate the commercially exploited fish stocks. Thus further studies are required to monitor their potential interactions on the Caspian Sea fauna
Molecular Methods for the Detection of Natural Hybrids in Sturgeon Populations
Authors: Burcea Alexandru , Florescu Iulia Elena , Dudu Andreea , Georgescu Sergiu Emil , Costache Marieta 
Published: September 2015

Abstract
Due to construction of the Iron Gates dams, the Lower Danube has suffered a decrease in sturgeon populations. The dams have decreased sturgeon habitat area, which in turn has caused an overlap of reproduction areas for all sturgeon species. The ease with which sturgeon species can create hybrid offsprings gave rise to an increase in the number of hybrid sturgeon species now found in the Lower Danube area. We propose a set of molecular methods for hybrid species using DNA markers represented by microsatellites and mitochondrial DNA. This identification data and methodology is important for use on sturgeon farms due to the need to correctly identify species of sturgeons. Using the proposed methodologies, it is possible to avoid identification errors that might appear when using only morphological criteria to idenfy sturgeons

Published: September 2015

Abstract
In the protected area ROSCI0229 Siriu were named three fish species of community interest: Gobio uranoscopus frici Vladykov, 1925, Barbus petenyi Heckel, 1847 and Cottus gobio Linné, 1758. Out of 193 fish collected in 2010, 49 were Barbus petenyi and 37 Cottus gobio. In the three monitored rivers (Buzău River, Siriu River, and Crasna River), Barbus petenyi was present in two of them and Cottus gobio was present in all of them. According to the analytical indices of population, frequency, numerical abundance and density we assessed a favorable population status for Barbus petenyi in Buzău River and a medium favorable population status for Cottus gobio in Buzău River and its tributaries Crasna River and Siriu River.
Effects of River Regulation on Plant Dispersal and Vegetation
Authors: Omelchuk Oksana , Prots Bohdan 
Published: September 2015

Abstract
This study compares the vegetation and seed deposits of free-flowing parts of a river with those regulated by straightening, as well as identifying the correlation between the breadth of the river-bed, existent vegetation and distribution of plant species along the river corridor. The 31 sampling plots in the Ukrainian Carpathians, at an equal distance of four km from each other, were positioned across different vegetation zones. Vegetation and seed bank data were collected. The study showed that effective distribution of plants has a place in native (non-regulated) river-corridors with a river-bed breadth of 15-30 m. The reduction and straightening of the river-bed decrease the number of species that can be dispersed along river. The percentage of seeds of alien species greatly increases, from 0.1% in the free-flowing to 10% in the regulated parts of rivers. River regulation causes transformation of native vegetation communities in these plots into associations of invasive herbaceous perennial species; such as associations of Helianthus tuberosus and Solidago gigantea. The analyses do not show a clear link between the breadth of the river-bed and number of invasive species in the vegetation community. The research suggests that river regulation has a clear negative effect on vegetation by decreasing the resistance of plant communities to alien species
Rhodeus Sericeus Amarus Bloch, 1782; Monitoring Elements in the New Natura 2000 Context in Croatia
Authors: Bănăduc Doru , Curtean-Bănăduc Angela 
Published: September 2015

Abstract
The action framework at the European Union level for the conservation of biodiversity was set up based on the Birds Directive (79/409/EEC) and Habitats Directive (92/43/EEC). One principal element of the implementation of these two significant Directives in Croatia is the set up of a Natura 2000 network of protected areas, a network which should be based on a specific monitoring plan at Croatian national level for each species which is considered of community interest. In this general context, this study suggests a set of monitoring elements for Rhodeus sericeus amarus for the Croatian Continental Biogeographical Region. The suggestions are based on eight selected criteria: Croatian national borders proximity sectors overlay; very good quality populations of Rhodeus sericeus amarus in terms of population density and structure (e.g. protected areas) in characteristic good habitats; habitats which need ecological reconstruction to allow this fish species populations structure ameliorate or natural repopulation; key sectors with importance for connectivity (e.g. lotic sectors between different important sectors, rivers confluence areas, etc.); sectors influenced by human impact like: industrial pollution point sources, sectors influenced by agricultural diffuse sources of pollution, sectors influenced by habitats modifications (watercourses remodeling, watercourses regulation, etc.), geographically extreme monitoring sections in the most-upstream and mostdownstream sections of the rivers, in this species range and in the near outer proximities of these extremes

Published: September 2015

Abstract
In this article, numerical simulations are carried out for fluid flow and heat transfer through natural convection in an isosceles triangular cavity under the effects of uniform magnetic field. The cavity is of cold bottom wall and uniformly/non-uniformly heated side walls and is filled with isotropic porous medium. The governing Navier Stoke's equations are subjected to Penalty finite element method to eliminate pressure term and Galerkin weighted residual method is applied to obtain the solution of the reduced equations for different ranges of the physical parameters. The results are verified as grid independent and comparison is made as a limiting case with the results available in literature, and it is shown that the developed code is highly accurate. Computations are presented in terms of streamlines, isotherms, local Nusselt number and average Nusselt number through graphs and tables. It is observed that, for the case of uniform heating side walls, strength of circulation of streamlines gets increased when Rayleigh number is increased above critical value, but increase in Hartmann number decreases strength of streamlines circulations. For non-uniform heating case, it is noticed that heat transfer rate is maximum at corners of bottom wall.

Abstract
The preparation, characterization and the molecular structure of a dinuclear uranyl complex [(UO2)2L(OCMe2)2] supported by the bis-salophen ligand N,N′,N″,N′″-tetra-(3,5-di-tert-butylsalicylidene)-1,2,4,5-phenylenetetraamine (L4–) is described. [(UO2)2L(OCMe2)2] was prepared by reaction of uranyl nitrate with the neutral, protonated form of the ligand (H4L) in acetone. From a saturated acetone solution [(UO2)2L(OCMe2)2]·1.5(OCMe2) crystallizes triclinically, space group P1̅ with a = 1522.7(2), b = 1751.4(2), c = 1815.4(2) Å, α = 109.16(1), β = 99.29(1), γ = 105.29(1)° and Z = 2. Each uranium atom is surrounded in a distorted pentagonal bipyramidal fashion by two O and two N atoms of the salicylidene units, one O atom of an acetone ligand, and the two oxo groups. The cyclic voltammogram of [(UO2)2L(OCMe2)2] shows two quasi-reversible redox processes centered at +0.57 V and +0.82 V vs. Fc+/Fc attributed to the sequential oxidation of the coordinating phenolates to phenoxyl radicals. The crystal structure of an ethanol solvate of H4L was also determined by X-ray crystallography. H4L·5EtOH: triclinic, space group P1̅, a = 1003.4(3), b = 1187.7(3), c = 1905.1(5) Å, α = 75.75(2), β = 78.74(2), γ = 66.66(2)°, Z = 1.

ContextThe role of 18F-labeled 2-fluoro-2-deoxy-d-glucose (FDG) positron emission tomography (PET)/computed tomography (CT) in the post-operative monitoring of patients with adrenocortical carcinoma (ACC) is still unclear.ObjectiveTo assess the accuracy of FDG PET/CT to diagnose ACC recurrence in a real world setting.Design and methodsRetrospective evaluation of data of 57 patients with presumed ACC recurrence at CT scan who underwent FDG PET/CT within a median time of 20 days. We compared the results of either FDG PET/CT or CT with a gold standard confirmation of recurrence (positive histopathology report of removed/biopsied lesions or radiological progression of target lesions at follow-up) to assess their diagnostic performance at different body sites to correctly categorize target lesions. We also assessed whether FDG PET/CT findings may be useful to inform the management strategy.ResultsIn 48 patients with confirmed ACC recurrence, we found that FDG PET/CT had lower sensitivity than CT in diagnosing liver and lung recurrences of ACC. FDG PET/CT had higher specificity than CT in categorizing liver lesions. FDG PET/CT had a greater positive likelihood ratio than CT to identify liver and abdominal ACC recurrences. The management strategy was changed based on FDG PET/CT findings in 12 patients (21.1%).ConclusionsThe greater sensitivity of CT may be partly expected due the specific inclusion criteria of the study; however, the greater specificity of FDG PET/CT was particularly useful in ruling out suspected ACC recurrences found by CT. Thus, use of FDG PET/CT as a second-line test in the post-operative surveillance of ACC patients following CT finding of a potential recurrence may have a significant impact on patient management.

Published: September 2015

BACKGROUND AND OBJECTIVES:
Choosing career paths can be difficult decisions for residents contemplating fellowship training. This study compares the experiences of early career pediatricians who did and did not pursue fellowships.

METHODS:
We analyzed national, weighted data from pediatricians 8 to 10 years after residency (n = 842). Work environment, work–life balance, and satisfaction were compared for pediatricians who had pursued fellowship training (fellowship trained) and those who did not pursue fellowship training (generalist trained). Logistic and linear regression examined the independent effects of fellowship training while controlling for demographic differences.

RESULTS:
A total of 39% of the pediatricians (328/842) pursued fellowship training. The fellowship-trained group was less likely than the generalist-trained group to spend time in direct patient care and more likely to report learning opportunities in their work environment. This group was also more likely to report an income of ≥$150 000, although no difference was found when only full-time pediatricians were examined. Generalist-trained pediatricians were more likely to work &lt;50 hours per week, have flexibility with their schedules, and be satisfied with time spent with their own children. Pediatricians in both the fellowship-trained and generalist-trained groups generally found their work to be rewarding and were satisfied with their lives.

CONCLUSIONS:
Although residents need to consider important life and career differences when contemplating fellowship training and general care, pediatricians in both groups can achieve overall life and career satisfaction.
High School Students’ Use of Electronic Cigarettes to Vaporize Cannabis
Authors: Morean Meghan E. , Kong Grace , Camenga Deepa R. , Cavallo Dana A. , Krishnan-Sarin Suchitra 
Published: September 2015

BACKGROUND AND OBJECTIVES:
Electronic cigarette (e-cigarette) use is increasing rapidly among high school (HS) students. Of concern, e-cigarettes can be used to vaporize cannabis, although use rates among adolescents are unknown. We evaluated lifetime rates of using e-cigarettes to vaporize cannabis among all lifetime e-cigarette users (27.9%), all lifetime cannabis users (29.2%), and lifetime users of both e-cigarettes and cannabis (18.8%); common means of vaporizing cannabis including hash oil, wax infused with Δ-9-tetrahydrocannabinol (THC), and dried cannabis; and demographic predictors of using e-cigarettes to vaporize cannabis.

METHODS:
In the spring of 2014, 3847 Connecticut HS students completed an anonymous survey assessing e-cigarette and cannabis use.

RESULTS:
Vaporizing cannabis using e-cigarettes was common among lifetime e-cigarette users, lifetime cannabis users, and lifetime dual users (e-cigarette 18.0%, cannabis 18.4%, dual users 26.5%). Students reported using e-cigarettes to vaporize hash oil (e-cigarette 15.4%, cannabis 15.5%, dual users 22.9%) and wax infused with THC (e-cigarette 10.0%, cannabis 10.2%, dual users 14.8%) and using portable electronic vaporizers to vaporize dried cannabis leaves (e-cigarette 19.6%, lifetime cannabis 23.1%, lifetime dual users 29.1%). Binary logistic regression indicated that male students (odds ratio [OR] = 2.05), younger students (OR = 0.64), lifetime e-cigarette users (OR = 5.27), and lifetime cannabis users (OR = 40.89) were most likely to vaporize cannabis using e-cigarettes. Rates also differed by HS attended.

CONCLUSIONS:
Rates of vaporizing cannabis using e-cigarettes were high. These findings raise concerns about the lack of e-cigarette regulations and the potential use of e-cigarettes for purposes other than vaping nicotine.
