Published: November 2017

Social workers work with children, with disabilities, with the elderly, with families. In short, with all client systems in the individuals and groups with harmed capacities to cope with the life challenges, in hospitals, community mental health centers, prisons, justice palaces and various social service organizations.Such a study requires that the vulnerable individual, the family and the groups to listen to the life events that cause trauma, to observe the life of the application system, to ask for sadness witness and help, and all these are inevitably absorbed by social workers.As a result of the interaction with the client system and the issue emerge secondary traumatic stress, which represents a similar pattern to posttraumatic stress disorder.Secondary traumatic stress; is described as traumatization associated with emotions and behaviors that arise as a result of learn client’s trauma knowledge and want to help clients who have suffered trauma experience or life difficulties. The purpose of this study is to examine the secondary traumatic stresses and dimensions in the context of the interaction of the social worker client system with the social work perspective on the factors that are effective in the emergence of secondary traumatic stress.Extended English abstract is in the end of PDF (TURKISH) file.ÖzetSosyal hizmet uzmanlarıyaşamsal zorluklarla baş etme kapasiteleri zarar görmüş birey ve gruplar ile hastanelerde, toplum ruh sağlığı merkezlerinde, ceza evlerinde, adalet saraylarında ve çeşitli sosyal hizmet kuruluşlarında çocuklarla, engellilerle, yaşlılarla, ailelerle kısacası tüm müracaatçı sistemleri ile çalışmaktadırlar.

Abstract
The aim of the study was to determine the quality and nutritional value of meat originating from pigs of Polish native pure breeds - the Puławska and Złotnicka Spotted as well as the commercial four-breed crossbreds F1 (Large White × Polish Landrace) × F1 (Duroc × Pietrain). Physicochemical properties of meat were evaluated, such as acidity, water holding capacity, tenderness, and color parameters. In addition, functional properties of meat were determined: nutritional value, mineral content and fatty acid profile. The dietetic indices of meat were also determined. The smallest acidity of muscle tissue was characteristic of the meat of the Puławska breed and the smallest meat drip loss was found in both native breeds (P≤0.01). This can confirm their greater technological suitability. The most tender was meat obtained from pigs of the Puławska breed (36.07 N/cm2). The darker color was characteristic of the pig meat of the Złotnicka Spotted breed (L* = 49.19) (P≤0.01). Meat of all three groups of the tested pigs had the quality characteristics related to normal meat. The highest content of protein was found in the Złotnicka Spotted meat (25.23%) at optimum fat content (2.25%). The high content of ash (1.63%) recorded in the Złotnicka Spotted meat meant higher content of macro and microelements, especially iron and zinc, as compared to meat of the four-breed crossbreds (P≤0.01). The highest amount of monounsaturated fatty acids (52.72%) was recorded in porcine meat of the Puławska breed, while content of polyunsaturated fatty acids was the highest in meat of the four-breed crossbreds (16.77% vs. 9.32% and 15.19%) (P≤0.01). No differences were found between the groups tested for atherogenic index. In terms of most physicochemical and functional characteristics, meat of native pig breeds was superior to the meat of commercial pigs from mass-production.
Effect of Thickness, Density and Cavity Depth on the Sound Absorption Properties of Wool Boards
Authors: Qui Hua , Enhui Yang 
Published: November 2017

Abstract
A novel wool absorption board was prepared by using a traditional non-woven technique with coarse wools as the main raw material mixed with heat binding fibers. By using the transfer-function method and standing wave tube method, the sound absorption properties of wool boards in a frequency range of 250-6300 Hz were studied by changing the thickness, density, and cavity depth. Results indicated that wool boards exhibited excellent sound absorption properties, which at high frequencies were better than that at low frequencies. With increasing thickness, the sound absorption coefficients of wool boards increased at low frequencies and fluctuated at high frequencies. However, the sound absorption coefficients changed insignificantly and then improved at high frequencies with increasing density. With increasing cavity depth, the sound absorption coefficients of wool boards increased significantly at low frequencies and decreased slightly at high frequencies.
Epigenetic regulation mechanisms of microRNA expression
Authors: Morales Sara , Monzo Mariano , Navarro Alfons 
Published: November 2017

AbstractMicroRNAs (miRNAs) are single-stranded RNAs of 18–25 nucleotides that regulate gene expression at the post-transcriptional level. They are involved in many physiological and pathological processes, including cell proliferation, apoptosis, development and carcinogenesis. Because of the central role of miRNAs in the regulation of gene expression, their expression needs to be tightly controlled. Here, we summarize the different mechanisms of epigenetic regulation of miRNAs, with a particular focus on DNA methylation and histone modification.
The Oslo Principles and the Enterprises Principles: Legal Strategies to Come to Grips with Climate Change
Authors: Spier Jaap 
Published: November 2017

AbstractIt is almost commonly accepted that we must keep the increase of global temperature below 2 degrees C and preferably below 1.5 degree C. This begs the question: do states and enterprises have concrete reduction and other obligations to stem the tide? The Oslo Principles, adopted on March 2015, tried to discern the legal obligations of states and to a lesser extent enterprises. The Enterprises Principles will map the legal obligations of enterprises, financiers and long term investors such as pension funds. Both set of principles are based on an interpretation of the law as it stands or will likely develop. This article and Philip Sutherland’s contribution to this volume focus on the core obligations of both the Oslo and the Enterprises Principles. Since the adoption of the Oslo Principles a lot has happened. This contribution also discusses a few key features of the Oslo Principles in light of these developments.
Adaptive Intervention Methodology for Reduction of Respondent Contact Burden in the American Community Survey
Authors: Ashmead Robert , Slud Eric , Hughes Todd 
Published: November 2017

Abstract
The notion of respondent contact burden in sample surveys is defined, and a multi-stage process to develop policies for curtailing nonresponse follow-up is described with the goal of reducing this burden on prospective survey respondents. The method depends on contact history paradata containing information about contact attempts both for respondents and for sampled nonrespondents. By analysis of past data, policies to stop case follow-up based on control variables measured in paradata can be developed by calculating propensities to respond for paradata-defined subgroups of sampled cases. Competing policies can be assessed by comparing outcomes (lost interviews, numbers of contacts, patterns of reluctant participation, or refusal to participate) as if these stopping policies had been followed in past data. Finally, embedded survey experiments may be used to assess contact-burden reduction policies when these are implemented in the field. The multi-stage method described here abstracts the stages followed in a series of research studies aimed at reducing contact burden in the Computer Assisted Telephone Interview (CATI) and Computer Assisted Personal Interview (CAPI) modes of the American Community Survey (ACS), which culminated in implementation of policy changes in the ACS.
How to Obtain Valid Inference under Unit Nonresponse?
Authors: Boeschoten Laura , Vink Gerko , Hox Joop J.C.M. 
Published: November 2017

Abstract
Weighting methods are commonly used in situations of unit nonresponse with linked register data. However, several arguments in terms of valid inference and practical usability can be made against the use of weighting methods in these situations. Imputation methods such as sample and mass imputation may be suitable alternatives, as they lead to valid inference in situations of item nonresponse and have some practical advantages. In a simulation study, sample and mass imputation were compared to traditional weighting when dealing with unit nonresponse in linked register data. Methods were compared on their bias and coverage in different scenarios. Both, sample and mass imputation, had better coverage than traditional weighting in all scenarios.
Imputation methods can therefore be recommended over weighting as they also have practical advantages, such as that estimates outside the observed data distribution can be created and that many auxiliary variables can be taken into account. The use of sample or mass imputation depends on the specific data structure.

Abstract
The use of CO2 as a feedstock for chemical synthesis is considered as a viable alternative option to some traditional processes. One of the most interesting challenge for the industry is represented by the CO2 coupling with olefins to produce acrylate. Only recently, with the choice of suitable ligands and the use of a sacrificial base, a selective catalytic reaction was established by using Ni(0)-based complexes. The one-pot reaction, which leads to the highest TON (107 mol/mol Ni, in 20 h) reported so far, was successfully developed starting from Ni(0)-based precursors in the presence of disphosphine ligands, a large excess of base and of finely powdered zinc. In the present paper, we carried out the catalytic synthesis of sodium acrylate from CO2 and ethene, in one-pot, by using Ni(II)-chloride and Pd(II)-chloride phosphine-complexes as precatalyst. The reaction occurs under basic conditions and without adding any external reductants. The Ni(II) complexes lead to higher TON than the respective Pd(II) precursors and the best results are obtained by using diphosphines having high bite angles. Such catalysis is favored by aprotic and polar solvents in which a TON of 290 mol/mol Ni is reached by using the [NiCl2(dppp)] precursor in DMSO. Furthermore the TON could be increased by increasing the temperature, the base concentration and by using diphosphine ligands having high bite angle.
Windows of the Soul in the Worldview of Philo of Alexandria
Authors: Botica Aurelian 
Published: November 2017

AbstractOne of the most important paradigm shifts in the history of Greek philosophy was the ‘rediscovery’ of transcendence in the movement of Intermediate Platonism. Less than a century before the birth of Hellenism (late 4th century BC), Plato had advocated an intentional preoccupation with the life of the mind / soul, encouraging the individual to avoid being entrapped in the material limitations of life and instead discover its transcendental dimension. The conquest of Athens by the Macedonians, followed by the invasion of the Orient by Alexander the Great, set in motion sociological and cultural changes that challenged the relevance of Platonic philosophy. The transcendental vision of Platonism left the individual still struggling to find happiness in the world created by Alexander the Great. This was the context in which the schools the of Cynicism, Stoicism, Epicureanism and Skepticism challenged Platonism with their call to happiness in this world and by means of the Hellenistic dominance and the rise of Roman supremacy stirred a renewed spiritual and philosophical effort to rediscover the world beyond; that is, the transcendental world of Plato. This was Middle Platonism and the Jewish philosopher Philo of Alexandria was one of its most prolific writers. In this paper, we will examine the concept of the soul in the writings of Philo, with an emphasis on the role that the soul plays in the act of approaching God through the means of the external / material cult (Temple, sacrifices, priests, etc.). Philo offers a complex vision of the soul, one that remains critically relevant to understanding the Greek, Jewish, and Christian thought that emerged after Philo.
Analysis of Phenomenels with Hydrologic Large Risk in the Hydrographic Basin of the Trotuş River
Authors: Avram Mihaela , Luca Mihail 
Published: November 2017

Abstract
The paper presents an analysis of the high hydrological risk phenomena formed in the hydrographic basin of the Trotuş River in the last period of time. The Trotuş River and the tributaries are monitored by 21 hydrometric stations. Precipitation volume processing indicated a number of risk factors that have prevailed over the last 20 years. The hydrological data processing revealed the presence of several flood flows in the same year. The effects of the floods have materialized through the excessive degradation of river bedside regulation and shore defence works. The floods of the past 25 years have resulted in the destruction of a large number of economic and social objectives in the Trotuş River area, as well as human losses. Parameters of hydroclimatic risk highlighted by research are represented by torrential precipitations, floods with high probability, high frequency of high-flow flows, formation of high erosion velocities of the bed, etc. Parameters of hydroclimatic risk impose special conditions for the design of river regularization and shore defence.
Survey on Road-Tyre Contact Patch Pattern and Wear Related Aspects
Authors: Azodo Adinife Patrick 
Published: November 2017

Abstract
Motor vehicle end-users approaches to tyre safety issues in automobiles translate to a number of tyre failure risk factors. This study basically assessed tread wear pattern of tyres in passenger cars used on Nigeria roads. The result obtained showed that 75.4% of the assessed tyres showed uneven wear pattern resulting from incorrect tyre-road contact effects. This observed high proportion of uneven tyre tread wear pattern implies high rate of inconsequential regard for tyre safety.

Published: November 2017

Abstract
The present study was focused on the fabrication of metal matrix and hybrid metal matrix composites through stir casting process. The Aluminium 6063 was used as base material and SiC/Al2O3 were used as reinforcement with varying weight %. The parametric study on a wire-cut electro discharge machine was carried out by using Taguchi Method. A statistical analysis of variance (ANOVA) was performed to identify the process parameters that were statistically significant. It was observed that the MRR decreases with increase in the percentage weight fraction of SiC and Al2O3 particles in the MMCs and HMMCs. Whereas, the surface roughness parameter increases with increase in the percentage weight fraction of SiC and Al2O3 particles due to the hardness of MMCs and HMMCs composites.

Abstract
By using the wrought aluminum alloys can be created castings with higher mechanical properties than the castings made of standard foundry aluminum alloys, but it is necessary to handle the process of making sound castings without any defects such as hot tears and shrinkage porosity. In experiments, we have been studied of wrought aluminum alloy EN AW-2024 which has been processed by the casting with crystallization under pressure with forced flow. Castings were heat treated by standard T6 heat treatment.
Visual rhetorical argumentation
Authors: Kjeldsen Jens E. 
Published: November 2017

AbstractIn semiotics and the study of pictorial communication, the conceptualization of visual rhetoric and argumentation has been dominated by two connected approaches: firstly, by providing an understanding of visual rhetoric through tropes and figures; and secondly, by interpreting pictures as texts that are read and decoded in the same way as words. Because these approaches provide an opportunity to understand pictures as a form of language, they contribute in explaining how pictures can be used to argue. At the same time, however, these approaches seem to under-communicate two central aspects of pictorial argumentation: its embedment in specific situations and the distinguishing phenomenological aesthetics of pictures. This paper argues that the study of visual argumentation must understand pictures both as languageandas a material aesthetic event. The possibility and actuality of visual argumentation is partly explained by understanding argumentation as a cognitive and situational phenomenon, and partly by introducing the notion of symbolic condensation. It is suggested that reconstruction of visual argumentation should be supported by reception analysis.
Static Load Test on Instrumented Pile – Field Data and Numerical Simulations
Authors: Krasiński Adam , Wiszniewski Mateusz 
Published: November 2017

Abstract
Static load tests on foundation piles are generally carried out in order to determine load – the displacement characteristic of the pile head. For standard (basic) engineering practices this type of test usually provides enough information. However, the knowledge of force distribution along the pile core and its division into the friction along the shaft and the resistance under the base can be very useful. Such information can be obtained by strain gage pile instrumentation [1]. Significant investigations have been completed on this technology, proving its utility and correctness [8], [10], [12]. The results of static tests on instrumented piles are not easy to interpret. There are many factors and processes affecting the final outcome. In order to understand better the whole testing process and soil-structure behavior some investigations and numerical analyses were done. In the paper, real data from a field load test on instrumented piles is discussed and compared with numerical simulation of such a test in similar conditions. Differences and difficulties in the results interpretation with their possible reasons are discussed. Moreover, the authors used their own analytical solution for more reliable determination of force distribution along the pile. The work was presented at the XVII French-Polish Colloquium of Soil and Rock Mechanics, Łódź, 28–30 November 2016.

Role of defectivity on the crystallography of martensitic transformations in Ti50Ni40Cu10: an XRD investigation
Authors: Coduri Mauro , Biffi Carlo A. , Bassani Paola , Tuissi Ausonio 
Published: November 2017

AbstractMartensitic transformations in Ni50Ti40Cu10are well known to proceed with a two-step process, from B2 austenite to monoclinic B19′ with intermediate orthorhombic B19. These transformations can be readily followed by X-ray diffraction especially in solution heat-treated materials through split and distribution of the main diffraction lines, while peaks broadening and overlap make the transformations more difficult to be described in highly defective materials. The present study addresses the effect of defects and chemical inhomogeneities on the martensitic transformation, placing particular emphasis on the crystallography of the low temperature B19 to B19′ phase transition. Lattice strains proved to be a powerful tool to monitor the martensitic transformations: whereas a clear discontinuity is observed for the solution heat-treated sample, defects promote a continuous progressive distortion from B19 to B19′. Calorimetry and internal friction investigations were added as a reference to verify the occurrence of the transformations and define the corresponding temperatures.
