A MUSTA-FORCE Algorithm for Solving Partial Differential Equations of Relativistic Hydrodynamics
Authors: Porter-Sobieraj Joanna , Słodkowski Marcin , Kikoła Daniel , Sikorski Jan , Aszklar Paweł
Published: December 2017

Understanding event-by-event correlations and fluctuations is crucial for the comprehension of the dynamics of heavy ion collisions. Relativistic hydrodynamics is an elegant tool for modelling these phenomena; however, such simulations are time-consuming, and conventional CPU calculations are not suitable for event-by-event calculations. This work presents a feasibility study of a new hydrodynamic code that employs graphics processing units together with a general MUSTA-FORCE algorithm (Multi-Stage Riemann Algorithm – First-Order Centred Scheme) to deliver a high-performance yet universal tool for event-by-event hydrodynamic simulations. We also investigate the performance of selected slope limiters that reduce the amount of numeric oscillations and diffusion in the presence of strong discontinuities and shock waves. The numerical results are compared to the exact solutions to assess the code’s accuracy.
Eine Behörde als simuliertes Unternehmen
Authors: Böick Marcus
Published: December 2017

After the fall of socialism in East Germany, a special organization known as the “Treuhandanstalt” organized the crisis-ridden transformation of about 8,000 formerly state-owned corporations from the planned to the market economy. Most of the time, this organization operated under much criticism and pressure from outside, but internal operations were also characterized by conflicts about “corporate identity”. While some saw the “Treuhand” as a politically dependent state bureaucracy, others regarded it as an autonomous corporation. This article examines this conflict zone between internal as well as external perceptions of the “nature” of the Treuhandanstalt. It concludes that this was a state organization, set up in exceptional times, as an administration simulating a corporation.
Das Universalbanksystem – Ein Erfolgsmodell auf den Finanzmärkten?
Authors: Wixforth Harald
Published: December 2017

The recent debate on the structure of financial systems created harsh criticism of the business policy of the great universal banks. Economists as well as prominent experts in banking demanded a strict control of their business or even their liquidation. On the other hand, the banks themselves, together with representatives of economic interest groups, defended the status quo. Their argument is that the universal banking systems created great benefits for the economy in several central European countries during the last 150 years. Historical evidence, however, reveals that this is not true. Universal banks were not an instrument to stabilize economies in times of crises. On the contrary, crises were aggravated by their business policy on several occasions. In sum, historical analysis shows that the actual business operations and influence of universal banks in modern economies have to be scrutinized closely.
Fractional Effects on the Light Scattering Properties of a Simple Binary Mixture
Authors: Rodríguez Rosalío F. , Fujioka Jorge , Salinas-Rodríguez Elizabeth
Published: December 2017

A fractional generalized hydrodynamic (GH) model of the concentration fluctuations correlation function is analyzed. Our analysis is based on a previously proposed irreversible thermodynamics non-fractional model that describes the first GH deviations in a finite frequency and wavelength regime where the local equilibrium assumption is not valid. Our basic purpose is to generalize this theory to investigate the time fractional effects on the intermediate scattering function (ISF) of a model of a binary mixture. We discuss two different forms of introducing the fractional derivatives into the hydrodynamic time evolution equation of the ISF and examine their consistency in the non-fractional limit. We calculate analytically the fractional intermediate scattering function (FISF) and compare it with the non-fractional one. We find that although the FISFs are in general less than ISF, the FISF may be a significant fraction of the ISF (∼36%) and might be measurable by light or neutron scattering techniques. We show that fractional time derivatives provide a consistent description of this correlation function in the GH regime and reduce to its well-known behavior in the Navier–Stokes limit (NS) where local equilibrium is restored. We also suggest an experimental verification of our results for near equilibrium states. Finally, we summarize the main results of our work and make some further physical remarks.
PIIN Cancellation Using a Novel Receiving Architecture for Spectral/Spatial SAC-OCDMA System
Authors: Bouarfa A. , Kandouci M. , Garadi A. , Djellab H.
Published: December 2017

Increasing the number of users presents a limitation in one-dimensional (1D) spectral amplitude coding (SAC) for Optical Code Division Multiple Access (OCDMA) system. In order to overcome this disadvantage, a new architecture of the two-dimensional wavelength/spatial SAC-OCDMA system using the multi-diagonal (MD) code has been proposed. The 2D-MD code possesses the same properties of 1D-MD code, which leads to total suppression of the multiple access interference. Unlike conventional receivers used in precedent studies, where the phase-induced intensity noise (PIIN) is a drawback, the suggested structure not only eliminates PIIN but reduces the system architecture. The results show that the user’s number reached by the proposed system is the user number’s multiplication of the 1D system and the couplers’ number. Moreover, the new 2D-MD system presents good performances at the high data rate.
Super-thermal light for imaging applications
Authors: Allevi Alessia , Cassina Silvia , Bondani Maria
Published: December 2017

We report on a new classical light source useful for ghost-imaging applications. The light is obtained by frequency doubling a conventional speckle pattern having an overall multi-mode thermal distribution. The frequency-doubled light acquires a super-thermal distribution, which induces higher correlations at a beam splitter and, as a consequence, a higher visibility in ghost-imaging protocols.
Examining the Policy Learning Dynamics of Atypical Policies with an Application to State Preemption of Local Dog Laws
Authors: Fix Michael P. , Mitchell Joshua L.
Published: December 2017

Most of the literature on policy diffusion focuses on palpable issues such as economic or morality policies. As such, we know little about the mechanisms of diffusion for preemption of atypical policies such as animal regulations that lack a clear economic or ideological motivation. In this article, we propose and test a theory of conditional policy learning to explain the diffusion of atypical policies. We posit that a type of policy learning is occurring here, but that states only look to their neighbors when certain policy specific factors are present in their state. His theory is then applied to examine the dynamics of state adoption of laws preempting local Breed Specific Legislation from 1988 to 2014. Using an exponential model, two policy learning and two conditional learning hypotheses are tested. This study finds that policy learning is occurring through both external and internal pathways. This advances the literature by demonstrating that preemption occurs through the learning mechanism, but this learning effect is conditioned on policy relevant factors within the state.

Published: December 2017

A series of new red-orange emission phosphors Na2BaMg(PO4)2:Pr3+ were synthesised by a high-temperature solid-state reaction. The crystal structure and photoluminescence properties of these samples were characterised by X-ray diffraction and spectroscopic measurements. This compound holds P3̅m1 space group of the trigonal system with the lattice parameters of hexagonal cell a=0.5304(3) nm and c=0.6989(3) nm. The phosphor emits the strongest peak at 606 nm when excited by 449 nm. The average Commission Internationale de l’Eclairage chromaticity coordinates calculated for the phosphors are (0.52, 0.46). The results demonstrate the potential application of these phosphors in solid-state lighting and other fields.
Correlation of Deformation Strain with the Tensile Properties and Fracture Mode of the AA 2014 Alloy Using Simulations and Experiments
Authors: Prabhu T. R.
Published: December 2017

The influence of deformation strain on the tensile properties of the forged bar was studied in the present study. An aerospace structural Al alloy (AA 2014) was selected for the experiments. In order to understand the strain distribution inside the forged bar, the forging process was simulated using the DEFORM3D finite element software. The model was used to predict the stress and temperature distributions. Tensile sample locations were identified based on the deformation strain values predicted by the model. The samples were tested under both notched and unnotched conditions. Variation of tensile properties with the deformation strain was correlated with the microstructure. The fractography of the tensile samples was analyzed with the aid of scanning electron microscopy to identify the failure mode. The important results of the present study are: (1) the strength and ductility properties increase with the increase of deformation strain for both smooth and notched conditions. However, this increase was not correlated to the strain. This uncorrelated variation was attributed to the complex variability in the grain size/structure in the material. (2) Microstructure examination revealed that the variation in the grain size reduced with the increase of deformation strain. The observed grain refinement with the increase of deformation strain was mainly attributed to the strain induced grain fragmentation and dynamic recovery. (3) The fractography of the smooth specimens showed that ductile fracture features, such as dimples and ductile tear regions, were more significant above a strain of 1.34, indicating improved ductility. On the other hand, for the notched specimens, brittle fracture features such as cleavage facets and ridges were predominant for all the strain value conditions. (4) The fracture appeared to be transgranular type in both the smooth and the notched samples for the tested strain range.
Stranger and Stranger
Authors: Rawlins L. Shelley
Published: December 2017

In this fusion of autoethnography and phenomenological description, I explicate my experiences as a door-to-door social welfare advocate for the Maine People's Alliance. Examining my lived experiences of being a stranger in the midst of facing other strangers in their homes, I reflect on the collaborative constitution of strangerdom. I also recount the possibilities of transcendence through dialogic negotiations and attempts at dismantling this threshold of unfamiliarity. I argue that autoethnographic inquiries that include portrayals of unknown others are productively informed by the descriptive richness of phenomenological variations.

Published: December 2017

Salmonid rickettsial syndrome (SRS), caused by the intracellular bacterium Piscirickettsia salmonis, is one of the main diseases affecting rainbow trout (Oncorhynchus mykiss) farming. To accelerate genetic progress, genomic selection methods can be used as an effective approach to control the disease. The aims of this study were: (i) to compare the accuracy of estimated breeding values using pedigree-based best linear unbiased prediction (PBLUP) with genomic BLUP (GBLUP), single-step GBLUP (ssGBLUP), Bayes C, and Bayesian Lasso (LASSO); and (ii) to test the accuracy of genomic prediction and PBLUP using different marker densities (0.5, 3, 10, 20, and 27 K) for resistance against P. salmonis in rainbow trout. Phenotypes were recorded as number of days to death (DD) and binary survival (BS) from 2416 fish challenged with P. salmonis. A total of 1934 fish were genotyped using a 57 K single-nucleotide polymorphism (SNP) array. All genomic prediction methods achieved higher accuracies than PBLUP. The relative increase in accuracy for different genomic models ranged from 28 to 41% for both DD and BS at 27 K SNP. Between different genomic models, the highest relative increase in accuracy was obtained with Bayes C (∼40%), where 3 K SNP was enough to achieve a similar accuracy to that of the 27 K SNP for both traits. For resistance against P. salmonis in rainbow trout, we showed that genomic predictions using GBLUP, ssGBLUP, Bayes C, and LASSO can increase accuracy compared with PBLUP. Moreover, it is possible to use relatively low-density SNP panels for genomic prediction without compromising accuracy predictions for resistance against P. salmonis in rainbow trout.
Production of Tomato Stalk Biochar and its Usage in Hydrophonic Agriculture
Authors: Ceren Karakaş  , Didem Özcimen
Published: December 2017

Tomato stalk is a waste remained after harvesting in agricultural productions. These wastes can be utilized as biochar for various purposes such as fuel, absorbent and soil improver. In this study, in order to waste utilization, biochar production from tomato stalk under different experimental conditions was carried out and effect of temperature, nitrogen gas flow and heating rate on yield of biochar was investigated. Characterization of biochar was performed with FTIR, TGA and SEM analysis. The highest biochar yield was obtained at the temperature of 773 K, heating rate of 5 K/min and inert gas flowrate of 500 ml/min. The highest yielded tomato stalk biochar was used as a supporting material for the tomato seedling planted in the hydroponic system of greenhouse. The tomato stalks obtained as a waste after harvesting in greenhouse were used for biochar production and biochars were applied as supporting material in greenhouse again, so, zero waste idea for a greenhouse was carried out. It has been observed that the supporting material provided a little more growth in the tomato seedling because of water and nutrient holding capacity.

Published: December 2017

Slightly more than one third of the global meat consumed comes from chickens. Various studies have been carried out on the use of bee pollen or probiotics in broiler feed; however, very limited studies have been carried out about their combined effect on broiler production. The objective of the present study was to investigate the effect of feeding by pollen and probiotics on broiler chicken Cobb 500. The effect of different concentrations of commercial bee pollen and probiotics was evaluated on growth performance, organs, and thigh meat pH of 45 days old chickens. The rate of body weight gain on day 21, 33, and 39 were significantly different among treatment and control groups and on day 33 d, all the experimental groups showed significant increase in weight gain as compared to control. T3 treatment had highest weight gain (380 g) on day 45. Some of the organs such as lung, digestive system, and intestine length were also significantly affected by the application of bee pollen and probiotics. The broilers fed with bee pollen and probiotics were found to have increased but more stable pH of thigh meat as compared to that of control at 24 hours of low temperature (-20°C) storage. At 24 h, T2 treatment showed highest pH value(6.52) for thigh meat Results of the present study indicated that the meat quality of broiler could be improved with the use of bee pollen and probiotics as they could increase and keep the pH stable during storage.

Authors: Prabhakarrao Pathak Anupama , Govindrao Rathod Mukundraj
Published: December 2017

Unkeshwar hot spring of Maharashtra was explored for the isolation of industrially important efficient thermostable protease producers. These isolates were identified based on their morphological characters, microscopic features, enzymatic profile and biochemical characteristics as Bacillus sphaericus APP21, Staphylococcus auricularis APP32, Microbacterium sp. APP41, and Kurthia sp. APP42 from Unkeshwar hot spring. Thermostable protease production was carried out using casein-yeast extract medium at 50 oC. Maximum specific activity of partially purified thermostable protease was recorded from Bacillus sphaericus APP21 (447.75 U/mg). Molecular weight of partially purified proteases from these isolates has been determined in the range of 14-29 KDa. These proteases have showed excellent thermostability in the range of temperature 45 to 65 oC. These proteases were catalytically active in the range of pH 7 to 9 and belonged to the class serine protease. Km and Vmax values were found in the range 5.26-8.34 mg/mL and 446-1380 U/mg respectively. The divalent cations Mg2+ and Mn2+ enhanced the catalytic efficiency of these proteases. These proteases showed excellent catalytic efficiency in presence of selected solvents, surfactants and detergents. These properties make them excellent candidates to use in detergent formulation, food processing, and in many biotechnologically important industries where proteolysis is needed at an elevated range of temperature.
UTILIZATION OF WHEY AS A CHEAP SUBSTRATE FOR THE OPTIMIZATION OF LIPASE PRODUCTION BY Bacillus subtilis B10 ISOLATED FROM DAIRY INDUSTRY
Authors: Kuppamuthu Kumaresan , Soundiraraj Sharath , Palanisamy Kanmani
Published: December 2017

Whey, a by-product of the dairy industry, acts as a prime source of environmental pollution due to its high organic load. Its utilization as a substrate for lipase production is an attractive option in facing the challenge associated with whey disposal. However, there are only very few studies that have reported the production of lipase using whey. In this study, 43 bacterial strains were isolated from dairy industry soil sample, of which, 26 were found to produce lipase. Since whey contains lactose as the sole carbon source, the ability of the isolates to utilize this sugar was tested and two of the isolates B3 and B10 were positive for growth in phenol red lactose broth. When they were cultured by submerged fermentation and their lipase activities quantified, strain B10 displayed 0.79U/ml of activity. In order to improve the production of lipase, one-factor-at-a-time method was used to study the impacts of oil inducers, nitrogen sources, mineral salts and whey concentration on the process. Statistical optimization was performed using the Box-Behnken design of Response Surface Methodology (RSM). From this design, 75% whey, 4% (v/v) sunflower oil, 0.625% (w/v) beef extract and 0.2% (w/v) CaCl2 were inferred to be the optimal conditions that resulted in a maximum lipase activity of 0.954U/ml. Analysis of variance indicated statistical significance of the model. Lipase being an industrially sought-after enzyme owing to its unique properties, this cost-effective route to its production from a waste substrate holds paramount environmental and economic significance.

Abstract:

To summarize actual knowledge on epidemiology, etiology, pathology, clinical apparence and treatment of ocular surface squamous neoplasias. We summarize up-to-date literature on conjunctival intraepithelial neoplasia and invasive squamous cell carcinoma and present some own cases. Ocular surface squamous neoplasia is the most common malignant ocular surface tumor and the third most common ocular malignancy following malignant melanoma and lymphoma. In spite of its low malignant potential, in advanced stages it may reduce visual acuity significantly or even the eye globe has to be removed. In case of metastasis it may also be life-threatening. As local recurrences of ocular surface squamous neoplasias may occur, knowledge of intra- and postoperative adjuvant treatment options are indispensable and regular control examinations are necessary. Identification and adequate treatment of ocular surface squamous neoplasias are necessary in order to avoid its progression and to prevent recurrences. Orv Hetil. 2017; 158(51): 2011–2022.

Zjawisko migracji Polaków. Następstwa i duszpasterska rola Kościoła
Authors: Dziedzic Jan
Published: December 2017

Migracje Polaków nie są zjawiskiem nowym. Już w XIX wieku Polacy podróżowali do USA i Kanady. W 1913 roku aż 40 proc. górników w Zagłębiu Ruhry stanowili Polacy. Migracje nie ustały po II wojnie światowej. Ich liczba wzrosła do 8 mln. Podobnie w latach od 1971 do 1989 Polacy szukali możliwości swojego rozwoju zagranicą. Migracje nie skończyły się także po roku 1989 i trwają do dziś. Statystyki wskazują, że obecnie najwięcej obywateli Polski wyjeżdża do Wielkiej Brytanii, Niemiec, Holandii oraz Irlandii.Wyjazdy zagraniczne mają skutki zarówno pozytywne, jak i negatywne. Do tych pierwszych zaliczamy poznanie języka obcego, nowej kultury i obyczajów, zapoznanie się z nowymi technikami produkcji, oprawę jakości i standardu ekonomicznego życia. Wśród skutków negatywnych podaje się: osłabienie więzi małżeńskich, a nawet rozpad małżeństwa, eurosieroctwo, osłabienie życia religijnego, większe prawdopodobieństwo chorób, pracę poniżej własnych kompetencji i aspiracji.O polskich emigrantach nie zapomina Kościół. Polskie Misje Katolickie działają na całym świecie. Mają one pomagać w rozwoju religijnym migranta, zapewniając mu opiekę duszpasterską. Obecnie duszpasterstwo polskojęzyczne regularnie prowadzi ponad 2 tys. duchownych. Podkreślają oni za Janem Pawłem II, który poprzez swoje spotkania z Polonią nakreślił program formacyjny dla emigrantów, że do istotnych elementów pracy nad sobą należą: zachowanie własnej tożsamości, integracja w nowym środowisku oraz budowanie zasad moralnych opartych na paradygmacie „bardziej być” niż „mieć”.
Przesłanie dla Polski św. Andrzeja Boboli
Authors: Warchoł Paweł
Published: December 2017

Każdy ze świętych ogłoszonych przez Kościół jest jedyny i niepowtarzalny w życiu i przesłaniu. Święty Andrzej Bobola błyszczy wśród nich wyjątkowością, gdyż inicjatywa wyniesienia na ołtarze nie wyszła od wiernego ludu, ale od niego, przebywającego już w królestwie Bożym. Jego prośba o kanonizację potwierdzona była skuteczną pomocą jezuitom w Pińsku, a potem w wyzwoleniu Polski z niewoli okupantów. Został także patronem Polski. Wobec tych znaków ludzie uwierzyli mu, dlatego z szacunkiem czcili jego ciało, które nie ulegało rozkładowi. Pomimo tylu nieszczęść nikt nie potrafił go zniszczyć. Do dziś leży w sanktuarium ku jego czci w Warszawie. Także w obecnych czasach św. Andrzej jest potrzebny do duchowego zmartwychwstania Polski. Przypomniał o tym w Strachocinie, objawiając się po raz trzeci i nakazując, aby go czcić.
Cone penetration testing in thinly inter-layered soils
Authors: Van der Linden Toon I. , De Lange Dirk A. , Korff Mandy
Published: December 2017

The effect of a soft layer on the cone resistance of a sand layer has been studied extensively, but the same cannot be said for the case of multi-layered deposits with many (thin) alternating soil layers. For geotechnical analyses based on cone penetration test data it is difficult to estimate a representative value of the cone resistance when encountering alternating thin layers of clay or peat and sand. This paper presents physical modelling tests to understand the ‘value’ of the cone resistance in thinly multi-layered soil deposits. The test results are compared with existing analytical methods. It is concluded that the characteristic resistance of the individual layers, the layer thicknesses relative to the cone diameter and the number of layers within the zone of influence of the cone affect the cone resistance in deposits containing multiple thin soil layers. Suggestions for practical implementation are also given.
Can Macroprudential Measures Make Cross-Border Lending More Resilient? Lessons from the Taper Tantrum
Authors: Takats Elod , Temesvary Judit
Published: December 2017

We study the effect of macroprudential measures on cross-border lending during the taper tantrum, which saw a strong slowdown of cross-border bank lending to some jurisdictions. We use a novel dataset combining the BIS Stage 1 enhanced banking statistics on bilateral cross-border lending flows with the IBRN’s macroprudential database. Our results suggest that macroprudential measures implemented in borrowers’ host countries prior to the taper tantrum significantly reduced the negative effect of the tantrum on cross-border lending growth. The shock-mitigating effect of host country macroprudential rules are present both in lending to banks and non-banks, and are strongest for lending flows to borrowers in advanced economies and to the non-bank sector in general. Source (lending) banking system measures do not affect bilateral lending flows, nor do they enhance the effect of host country macroprudential measures. Our results imply that policymakers may consider applying macroprudential tools to mitigate international shock transmission through cross-border bank lending.

Published: December 2017

Antecedentes: El conocimiento taxonómico y florístico de las plantas vasculares del norte de México presenta avances relevantes, aunque disgregados. Por lo anterior, es crítico hacer un diagnóstico para definir estrategias que los unifiquen y complementen.
Preguntas: ¿cuál es la riqueza y endemismo de las plantas vasculares en el norte de México?, ¿en cuáles de sus áreas deben concentrarse los esfuerzos de exploración?
Sitio de estudio: norte de México (Chihuahua, Coahuila, Durango y Nuevo León).
Métodos: Se desarrolló una base de datos de plantas vasculares del norte de México a partir de la del Herbario CIIDIR, complementada con registros provenientes de la Universidad de Chihuahua, Universidad Antonio Narro y Universidad de Nuevo León, así como de revisión de trabajos taxonómicos y de los herbarios ANSM, CFNL, CIIDIR y FZ-UACH. Se calculó la riqueza y endemismo por estado y por ecorregión; se definieron los grupos y áreas geográficas mejor conocidos y los huecos en conocimiento; y se elaboró una relación de los herbarios, programas en botánica y botánicos en la región.
Resultados: Se registran 8,503 especies, 1,599 géneros y 210 familias de plantas vasculares; 15 géneros son endémicos estrictos de la región. La mayor riqueza se registra para Durango (4,954 especies, 58 % del total). La Sierra Madre Occidental (en su porción para la zona estudiada) es la ecorregión con más especies (3,565), seguida por la Sierra Madre Oriental (2,862) y el Desierto Chihuahuense (2,602). Chihuahua y la Sierra Madre Occidental son el estado y la ecorregión menos explorados, mientras que la ecorregión mejor explorada es el Desierto Chihuahuense.
Conclusiones: Las cifras de riqueza y endemismo presentadas reflejan el estado del conocimiento actual, sin embargo, se requiere incrementar los inventarios florísticos, las revisiones taxonómicas y los estudios ecológicos para contar con información más precisa y exacta del panorama real.
Nódulos de Schmörl en una serie esqueletal contemporánea de La Plata, Argentina
Authors: Plischuk Marcos , Desántolo Bárbara , García Mancuso Rocío
Published: December 2017

Los Nódulos de Schmörl (NS) son hernias verticales del disco intervertebral que generan depresiones en ambas caras de los cuerpos vertebrales. Las causas propuestas como generadoras de NS son numerosas: edad, sexo, predisposición génica, patologías preexistentes, morfología vertebral, procesos evolutivos y actividades ocupacionales. Este trabajo tiene como propósito analizar las relaciones entre sexo, edad, severidad y ubicación de los NS en una muestra contemporánea de carácter documentada, integrada por 100 individuos pertenecientes a la Colección Lambre, alojada en la Facultad de Ciencias Médicas, Universidad Nacional de La Plata, Argentina. Todos los individuos son adultos, con edades entre 22 y 101 años, siendo  67 de sexo masculino y 33 de sexo femenino. Los NS fueron registrados según su ubicación y severidad y analizados en relación al sexo y la edad de muerte de los individuos. La prevalencia estimada para el total de la muestra fue de un 27%. No se encontraron  diferencias significativas en las prevalencias por sexos ni se encontró una correlación entre la cantidad de lesiones y la edad de los individuos. La zona vertebral más afectada fue la toracolumbar con muy escaso compromiso cervical y sacro. Las lesiones fueron leves en su mayoría, presentándose con mayor frecuencia en el centro de la vértebra, indistintamente en su cara superior e inferior.  La prevalencia total es coincidente con estudios de poblaciones contemporáneas aunque existe una gran disparidad en torno a esta frecuencia. El área toracolumbar se vería más afectada por recibir parte de la carga correspondiente al bipedismo, lo cual sumado a defectos en los tejidos articulares y, en menor medida, actividades ocupacionales explicarían en su conjunto la dinámica de las hernias discales verticales.

Sabendo da variedade de materiais existentes, buscou-se um conhecimimento prático que indicasse um  material que possa ser escolhido para essa moldagem com mais segurança, que apresente ao final uma prótese com boa retenção e estabilidade. Realizou-se coleta no prontuário de uma paciente onde haviam sido confeccionadas duas próteses totais, onde uma foi utilizado na moldagem funcional um material elástico e na outra um material anelástico. É possível perceber na prática clínica que um grande número de profissionais utilizam mais os materiais elásticos na moldagem pelas vantagens apresentadas, vantagens essas que foram possível vivenciar neste estudo, como uma melhor manipulação, manuseio, limpeza dos resíduos e o resultado final.
Layered composite increasing the resistance of patrol and intervention vehicles to the impact of improvised explosive devices (IED) from below
Authors: Szudrowicz M.
Published: December 2017

Model layered composites were made of polyester resin reinforced with layers of glass fibre and aramid fibre fabrics. The fabrics
for the study were selected in a manner enabling the comparison of their ballistic resistance depending on the material type and
density. Additionally, aluminium plates were used to produce the composites.The study examined the resistance of the model
composites to 1.1 g fragment simulating projectile (FSP) penetration, their susceptibility to deformation caused by shock waves
produced by pure TNT charges, and their resistance to the effects of detonation of model improvised explosive devices (IED)
containing fragments in the form of bearing balls. The analysis and optimisation of the test results enabled the selection of a layer
configuration combining the materials studied that has the lowest area density and that protects car bottom structures against
perforation in the case of a detonation of a small improvised explosive device.

The article adduces a research of psychological characteristics of information security of adolescents with deviant and normative behavior. 46 people from two Moscow schools were examined with a complex of four methods, one of which was the “Information Security Questionnaire" - is used for the first time. In addition, two experimental subgroups viewed videos about Internet security rules and then it was assessed how much it had influenced the responses of adolescents to spam mailing. A conclusion based on the obtained results was made, that adolescents with deviant behavior are less likely (in comparison with adolescents with normative behavior) to be exposed to negative information because of their personal characteristics and distrust of others. However, for the same reason, they are less susceptible to persuasive educational impact, including those related to information security on the Internet. Thus, it is teenagers with normative behavior who are the ones who need information security education, and the effectiveness of such education should be tested with various psychological methods.

The article examines the impact of the training programmes of mediation in special educational institution (SUVA) and educational institutions (ei) on the psychological climate in the team. The research is based on data obtained from 154 people, employees of educational institutions. Of them, 37 persons – employees of SUVA, and 117 bangs – employees OU.
There were three methods of psychological diagnostics - Methods of assessment of psychological atmosphere in the team at A. F. Fielder, index Sikora and assessment of communicative skills.
When comparing the performance of tests to conduct training programs on the basics of mediation and after its passage determined that among the staff of the SUVA (in analysis Wilcoxon test, p = 0,0027) and staff of the OU (in the test analysis Wilcoxon p <0.0001) is statistically significant increase in the level of group cohesion, defined in test Sisera.
Obtained data on scales methods for the assessment of psychological atmosphere in the team at A. F. Fielder. According to the results of this study are the employees of SUVA has not been a statistically significant change in rates of bipolar scales that measure different quality characteristics of the atmosphere in the team. At that time, as the employees OU for all the ten scales produced statistically significant differences, indicating improvement.
In the test of evaluation of communicative skills not observed statistically significant differences neither in the group of the SUVA (in analysis Wilcoxon test, p=0,079) or in the Oh group (in analysis Wilcoxon test, p=0.95) of employees.
The results of the study indicate that learning the basics of mediation contributes to the improvement of several characteristics of the psychological climate within the collectives, SUVA and OU. At the same time, there are fundamental differences between the groups of those agencies that require additional testing.
RETHINKING FEAR AND PROTEST: RACIALIZED REPRESSION OF ARAB AMERICANS AND THE MOBILIZATION BENEFITS OF BEING AFRAID*
Authors: Azab Marian , Santoro Wayne A.
Published: December 2017

Most scholars believe that fear thwarts activism unless it is suppressed or transformed. We challenge this view. We argue that for racialized minorities, people for whom fear is rooted in daily lived experiences, fear mobilizes unless it is at extreme levels. We investigate this claim using the Detroit Arab American Study (2003), a representative sample of Arab Americans in metropolitan Detroit shortly after 9/11. Multivariate analyses support our curvilinear thesis: Arab Americans with intermediate levels of fear protest more than people unafraid as well as those with intense fear. Our findings suggest that fear can be a useful tool for organizers and speculate that fear is a racialized emotion because of the role the state plays in producing it. The vitriolic rhetoric of the Trump administration toward minority populations provides scholars a plethora of future opportunities to investigate how the emotional consequences of racialized repression affect political participation.
