Figuring Figures: Exploring Europeans’ Knowledge of Official Economic Statistics
Authors: Vicente Maria R. , López Ana J. 
Published: November 2017

Abstract
Economic issues have been a major concern for Europeans in the last few years. In this context, it is reasonable to suppose that people are aware of the main economic figures regarding Europe. But are they really familiar with them? Do they know what the rates of growth, unemployment and inflation are?
The aim of this article is to explore the level of knowledge of these three economic indicators among Europeans. Several regression models are specified and estimated in order to identify the relationship between an individual’s knowledge and their socioeconomic profile, use of the Internet, perceived importance of economic issues and official statistics and trust in them. Cross-country differences are also assessed.

Published: November 2017

Abstract
This study is based on 3 years of hourly observations of global solar radiation (2014-2016), at a new weather station installed in the region of Central Moldavian Plateau, at Mădârjac (47.05°N, 27.25°E, 270 m). The main characteristics of annual, monthly and daily regime of global radiation were emphasized using for comparison similar data from Iașioficial weather station. Smaller annual amount of global solar radiation than those observed in previous studies were observed, reaching 4734 MJ/m2 in Iași and 4454 MJ/m2 in Mădârjac. An altidudinal gradient of global solar radiation close to 140 MJ/m2 was identified for the hilly region of Moldova. Despite the overall higher values in Iași, 30% of days indicates higher values of this parameter at Mădârjac weather station. These results can be used for the evaluation of the photo-voltaic potential in the region, but also to understand the altitudinal differences of solar radiation in the hilly region in Moldavia, since the only long-range actinometric stations from this part of Romania, Iași and Galați, are located at low altitudes.
2006-2012 Land Cover and Use Changes in Romania – An Overall Assessment Based on Corine Data
Authors: Petrişor Alexandru-Ionuţ , Petrişor Liliana Elza 
Published: November 2017

AbstractLand cover and use changes are an important component of the global changes, and in relationship with their transitional dynamics reflect the impact of socio-economic transition. This study is aimed at exploring the land cover and use changes occurred during 2006-2012 in Romania with respect to their spatial distribution over the regions of development and main transitional dynamics. The results suggest that the main drivers of change are deforestation and urbanization, accounting for 3/4 of all changes, and that the most affected regions are the northwest, southwest, center and northeast ones. Overall, the findings suggest a continuation of the trends from the previous periods, characteristic to transition economies.

Tornadoes in the Moldavian Plateau – Between Myth and Reality
Authors: Paraschiv Viorel , Machidon Ovidiu-Miron 
Published: November 2017

Abstract
All those who spent our holidays in the countryside to our gradparents or relatives, we heard about the elders’ stories about storms that rained frogs and fish. I also remember such a story that occured in the villages of Covasna river basin in 1970. The elders were speaking about such a heavy rain accompanied by fish that would have occurred due to an overheating of the active surface in July or August 1946 as well as in 1968 (!). Then, out of the blue, out of the forest, from ESE, black clouds accompanied by thunder and lightning occured, while frogs and fish fell among heavy drops of dirty rain.

Published: November 2017

Abstract
Nowadays, the operating nuclear reactors are able to utilise only 1 % of mined out uranium. An effective exploitation of uranium, even 60 %, is possible to achieve in so-called fast reactors. These reactors commercial operation is expected after the year 2035. Several design configurations of these reactors exist. Fast reactors rank among the so-called Generation IV reactors. Helium-cooled reactor, as a gas-cooled fast reactor, is one of them. Exchangers used to a heat transfer from a reactor active zone (i.e. heat exchangers) are an important part of fast reactors. This paper deals with the design calculation of U-tube heat exchanger (precisely 1-2 shell and tube heat exchanger with U-tubes): water – helium.

Authors: Ćwirko Marcin , Jastrzębska Małgorzata , Kwiecień Sławomir 
Published: November 2017

AbstractThe aim of this paper was to find an answer to the question about the possibility of using steel welded mesh in building the retaining walls of gabion baskets. In light of the currently used gabion structure solutions, among which double-woven mesh is much more popular, the focus was put on the possibility of using welded mesh. A numerical analysis was conducted to examine the behavior of welded and woven mesh subjected to various loads and the results obtained for both types of mesh were directly compared. The maximal displacement in mesh nodes was admitted as the measurement of the system behavior (in the case of both undamaged and damaged mesh).
Non-Isothermal Constitutive Relations and Heat Transfer Equations of a Two-Phase Medium
Authors: Uciechowska-Grakowicz Anna , Strzelecki Tomasz 
Published: November 2017

AbstractIn the case of a two-phase medium – such as the soil, which consists of an elastic skeleton and is filled with pore fluids – stress and strain within the medium are dependent on both phases. Similarly, in the case of heat transfer, heat is conducted through the two phases at different rates, with an additional heat transfer between the phases. In the classical approach to modelling a porous medium, it is assumed that the fluid filling the pore space is water, which is incompressible. In the case of gas, the volume of which is strongly dependent on temperature and pressure, one should take this behavior into account in the constitutive relations for the medium. This work defines the physical relations of a two-phase medium and provides heat transfer equations, constructed for a porous, elastic skeleton with fluid-filled pores, which may be: liquid, gas, or mixture of liquid and a gas in non-isothermal conditions. The paper will present constitutive relations derived from the laws of irreversible thermodynamics, assuming that pores are filled with either a liquid or a gas. These relations, in the opinion of the authors, may be used as the basis for the construction of a model of the medium filled partly with a liquid and partly with a gas. It includes the possibility of independent heat transfer through any given two-phase medium phase, with the transfer of heat between the phases.

Application of Change of Direction Deficit to Evaluate Cutting Ability
Authors: Cuthbert Matthew , Thomas Christopher , Dos'Santos Thomas , Jones Paul A. 
Published: November 2017

Abstract
Cuthbert, M, Thomas, C, Dos'Santos, T, and Jones, PA. Application of change of direction deficit to evaluate cutting ability. J Strength Cond Res 33(8): 2138–2144, 2019—The purpose of this study was to examine the application of the change of direction deficit (CODD) to a 90° cut test to examine whether CODD provides a unique evaluation of an individual's cutting ability. Thirty-six male collegiate team–sport (23 Rugby/13 Soccer) athletes (age: 20 ± 1.4 years; height: 1.80 ± 0.08 m; mass: 83 ± 13.2 kg) participated in the study. Each athlete performed 3 trials of a 20-m sprint (with 5 and 10 m splits) and 2 change of direction (COD) tests (90° cut and 505 tests) cutting/turning from both legs. Completion times for all sprint and COD tests were measured using timing cells. For both COD tests, CODD was determined (COD completion time—10 m sprint time). Pearson correlation was used to explore the relationships between sprint times and CODD and completion times. Significant (p < 0.001) moderate-to-large (r ≥ 0.467) correlations between sprint times and 90° cut completion times for left and right cuts were observed. Nonsignificant (p > 0.05) trivial-to-small correlations (r ≤ 0.199) were found between sprint variables and 90° cut CODD. Significant (p < 0.001) large to very large correlations (r ≥ 0.531) were revealed between the left and right 90° cut and 90° cut CODD. The results suggest that the CODD could be applied to isolate and assess the cutting ability in COD speed tests that involve a single cutting maneuver. Failure to inspect CODD could lead to incorrect evaluation of an athletes cutting or COD ability.

PSYCHOLOGICAL STRESS AND BREAST CANCER INCIDENCE: A SYSTEMATIC REVIEW
Authors: Chiriac Valentina-Fineta , Baban Adriana , Dumitrascu Dan L. 
Published: November 2017

Objective. Breast cancer is the world's leading cause of cancer mortality in women. Stress is an imminent risk factor with a documented negative impact on neuro-endocrine and immune system. Numerous epidemiological studies have investigated the link between stress and cancer, reporting contradictory results from no association to a close causal link. The impact of the topic and the lack of conclusion compelled this systematic review.Methods. A systematic review was carried out, including all literature studies from 1966 to 2016, investigating the relationship between stress and the occurrence of breast cancer. Of the 1813 articles identified in the PubMed/Medline database, 52 were eligible and included in the analysis.Results. A number of 17 retrospective, 20 limited prospective and 15 prospective studies were analyzed. The number of patients exceeded 29,000, for a total number of more than 700.000 women recruited from hospital, screening cohorts or population registers. We identified 26 positive articles linking personal traits, stressful events and breast cancer, 18 negative articles that did not confirm their hypothesis and 8 articles that could not be classified. Facing heterogeneity, all possible misguiding factors such as: study design, information gathering, stress type, moment of exposure, individual susceptibility and personality, were discussed independently.Conclusions. Qualitative analysis of articles has revealed a possible association between stress and cancer, especially regarding stressful life events. In the absence of a meta-analysis and taking into account the methodological heterogeneity of the studies, the results are difficult to interpret and the role of chance is difficult to exclude.

AbstractThis research was carried out in order to evaluate metric characteristics of the HEDUQUAL scale, whose purpose is to assess quality of service in higher education institutions. The same scale can be used for further research among student population. The research sample consisted of 257 students (of both sexes) from three higher education institutions from Autonomous Province (AP) Vojvodina. Metrics of the HEDUQUAL scale was tested via three procedures: 1) evaluation of the scale’s internal consistency (Scale Reliability Analysis which is based on Cronbach’s alpha coefficient); 2) evaluation of validity based on internal correlation coefficient of the scale (Spearman’s rank correlation – rho); and 3) factor analysis (analysis of the main components – Principal Components Analysis) using the method of Direct Oblimin rotation. All statistical conclusions were made at the level of significance of 0.05 (Sig.  .05). The results indicate that the tested instrument is valid, reliable and that it should be used as a multi-item and one-factor scale in further research on student population. Key words: HEDUQUAL scale; multi-item one-factor scale; reliability; students; validity. ---SažetakIstraživanje je provedeno s ciljem provjere metrijskih karakteristika HEDUQUAL skale, koja je namijenjena procjeni kvaliteta usluga visokoškolskih ustanova.

Authors: Dedios M. Ninell J. 
Published: November 2017

Objetivo: analizar el comportamiento del nivel de radiación ultravioleta incidente en Piura y cómo influye en las personas en edad escolar según su fototipo.
Metodología: el registro de datos ultravioleta se basó en la información procedente del sensor meteorológico IUV Biometer modelo 501-A (Solar Light), SN 10734 (respuesta espectral 250/380 nm) durante el periodo 20082011. Se seleccionaron al azar 25 instituciones educativas donde se evaluó la existencia de algún tipo de techado sobre las áreas recreativas y se determinó el fototipo de los estudiantes.
Resultados: en Piura los niveles de radiación ultravioleta UVB están en el rango de 8 a 15 UVB, que corresponde a niveles de riesgo Moderado a Extremo y presentan dependencia con la estacionalidad. Las horas de mayor impacto sobre la piel ocurren entre 11:00 a.m. a 14:30 p.m., siendo las 12:00 la hora en que la población debe tener un mayor cuidado por la sobreexposición solar. El fototipo III (piel morena clara) se identificó como el más frecuente y sensible comparado con los fototipos IV (piel morena oscura) y V (piel oscura). El 31,91 % de los alumnos (6.046) realizan sus actividades diarias de deporte o recreativas en áreas cubiertas y el 9,03 % (1.711) con techado parcial, mientras que el 59,07 % (11.193) se exponen diariamente a la radiación solar debido a que en su institución educativa no tiene un mecanismo externo de protección solar.
Beyond Nazi War Crimes Experiments: The Voluntary Consent Requirement of the Nuremberg Code at 70
Authors: Annas George J. 
Published: November 2017

The year 2017 marks both the 70th anniversary of the Nuremberg Code and the first major revisions of federal research regulations in almost 3 decades.I suggest that the informed consent provisions of the federal research regulations continue to follow the requirements of the Nuremberg Code. However, modifications are needed to the informed consent (and institutional review board) provisions to make the revised federal regulations more effective in promoting a genuine conversation between the researcher and the research subject.This conversation must take seriously both the therapeutic illusion and the desire of both the researcher and the research subject not to engage in sharing uncertainty.
Exposure to Marijuana Marketing After Legalization of Retail Sales: Oregonians’ Experiences, 2015–2016
Authors: Fiala Steven C. , Dilley Julia A. , Firth Caislin L. , Maher Julie E. 
Published: November 2017

Objectives. To assess exposure to marijuana advertising in Oregon after the start of retail marijuana sales in October 2015. Methods. We conducted a repeated cross-sectional online survey of 4001 Oregon adults aged 18 years and older in November 2015 and April–May 2016. We assessed subgroup differences by using the Pearson χ2 test. Results. More than half of adults (54.8%) statewide reported seeing marijuana advertising in the past month. These adults reported that they most frequently saw storefront (74.5%), streetside (66.5%), and billboard (55.8%) advertising. Exposure did not significantly differ by participant’s age or marijuana use but was higher among those living in counties with retail sales (56.5%) than in counties without (32.5%). Conclusions. Most adults reported exposure to marijuana advertising following the start of retail marijuana sales in Oregon. People who do not use marijuana and those aged 18 to 24 years were as exposed to advertising as other groups. Public Health Implications. Advertising restrictions may be needed to protect youths and young adults from pro-use messages. Commercial free speech afforded by the First Amendment makes advertising restrictions challenging, but public policy experts note that restrictions aimed at protecting youths may be allowed.
A Combined Distal Tibial Turn-up Plasty and Intercalary Calcaneal Osteocutaneous Fillet Flap for Salvage of a Transtibial Amputation
Authors: Wade Sean M. , Harrington Colin , Fleming Mark , Potter Benjamin K. 
Published: November 2017

Case:
This case demonstrates the successful attempt at a combined distal tibial turn-up plasty and intercalary calcaneal osteocutaneous fillet flap to increase functional limb length in order to salvage a transtibial amputation following a high-energy blast injury.

Conclusion:
A transtibial amputation is preferred over more proximal levels of amputation because of the decreased energy expenditure that is required for ambulation. In cases where there is not enough viable tibia to allow for a transtibial level of amputation, combining a calcaneal osteocutaneous fillet flap with a distal tibial turn-up plasty can be utilized to optimize residual limb length for a transtibial amputation.

Published: November 2017

* Numerous single-row and double-row repair suture techniques are used in performing arthroscopic rotator cuff repair. However, to our knowledge, there remains no clear consensus on the optimal suture technique for rotator cuff repair.* Biomechanical studies have found double-row fixation to be stronger than single-row fixation techniques and massive cuff stitch or modified Mason-Allen techniques to have the strongest fixation of single-row techniques.* Some clinical studies have shown improved healing rates for double-row repair suture techniques for larger tear size (>3 cm), but the majority of clinical studies have shown no difference in outcome scores among different suture techniques.* Obtaining healing in rotator cuff repair is multifactorial. Suture technique is one of many elements that may play a role in obtaining rotator cuff healing and successful clinical outcomes.
