Implications of media violence on the aggression in children and adolescents

Since the twentieth century, studies have demonstrated the impact of media channels on their beneficiaries, especially children and adolescents. From the transmission of moving images, the concept of information rapidly expanded both vertically, through technological development and improved information quality in terms of details, and horizontally, by broadening the target audience. Gradually, in the contemporary society the written press, television and radio have entered almost all the houses in various ways.The impact of mass media has evolved with technology, currently a large number of social events having the press as their trigger element. In this paper the authors start with a case study to illustrate the negative impact that violence conveyed through media channels can have on children and adolescents by generating or increasing their aggressiveness.
EM-based optimization of a single layer SIW with microstrip transitions using linear output space mapping

A computationally efficient linear output space mapping technique is proposed in this work to optimize single-layer SIW interconnects with microstrip transitions using full-wave electromagnetic simulators. The initial design of the SIW structure is obtained from empirical equations. A very low-resolution EM model with solid walls (grooves) and lossless metals is exploited as an efficient surrogate for direct EM optimization. The surrogate model is enhanced by developing an output linear mapping over a large region of interest, centered at the optimal coarse model solution. The enhanced interpolated surrogate is re-optimized to find the optimal transition. An excellent match is obtained between the original fine model and the enhanced surrogate model at the optimal solution found. The proposed technique is illustrated by designing a 10–50 GHz SIW interconnect with microstrip transitions on a standard FR4-based substrate.
Model appropriateness for simulation climate change and river flooding

An important question in water resources and related subjects is how an appropriate model should look given a specific research area and objective. This question is dealt with by developing a model appropriateness procedure based on model uncertainties. The procedure has been applied to a river basin model meant to assess the impact of climate change on flooding in a large river basin to illustrate the approach. This application indicated that the procedure gives a nice indication in which direction most profit can be gained when an appropriate model should be obtained. Moreover, the results showed that a decrease of input uncertainties and uncertainties associated with the transformation of rainfall to effective rainfall were of particular importance. However, these latter results should be interpreted with caution given the uncertainties in the procedure
Detection of high intensity thz radiation by field effect transistors

Terahertz power dependence of the photoresponse of field effect transistors, operating at frequencies from 0.1 to 3 THz for incident radiation power density up to 100 kW/cm2 was studied InGaAs high electron mobility transistors. The observed signal saturation behavior is explained by analogy with current saturation in standard direct currents output characteristics. The theoretical model of terahertz field effect transistor photoresponse was developed shows a good description match with experimental data. Our experimental results show that dynamic range of field effect transistors based terahertz detectors is very high and can extend from mW/cm2 up to kW/cm2.
Pneumococcal Infections and Pneumococcal Vaccine: An Update

Abstract Pneumococcal pneumonia continues to be an important disease in terms of prevalence, morbidity and mortality. With the discovery of penicillin and its wide clinical use, the overall mortality of pneumococcal pneumonia has been significantly reduced, but problems remain. These include: 1) death rate is uninfluenced by the antibiotic in the first five days of illness; 2) death rate in certain high risk groups and in patients infectecd with type 3 pneumococcus exceeds 25%; and 3) penicillin resistant strains of pneumococci have emerged. Because of these and other considerations, a modern 14-valent pneumococcal vaccine has been developed by Robert Austrian and his co-workers. The vaccine has been found to be immunogenic and effective in a number of populations studied. Additional efficacy studies are needed, however, particularly in certain high risk groups, such as the elderly and immunocompromised patients.
Pit pattern diagnosis of early colorectal carcinoma by magnifying colonoscopy: clinical and histological implications.

The relation between subclassification of V type pit pattern and histopathologic features, particularly, in regards to the invasion depth, was examined in 75 cases of early colorectal carcinoma. After we classified two grades (VA, VN) of V type pit pattern, we subclassified VN type pit pattern into three subtypes (Grade A, B, and C) according to the degree of appearance of VN pit pattern. V type pit pattern subclassification was diagnosed with use of a magnifying colonoscope. There were 37 VA type lesions, 8 VN.Grade A type, 16 VN.Grade B type, and 14 VN.Grade C type lesions. The incidence of submucosal massive invasion (sm2, sm3) rates was 5 (14%) of the 37 VA type lesions, 3 (38%) of the 8 VN.Grade A type, 15 (94%) of the 16 VN.Grade B type and 14 (100%) of the 14 VN.Grade C type lesions, respectively. The incidence of desmoplastic reaction (++) levels in VN.Grade B and C type lesions was significantly higher than that in VA type lesions (P<0.01), and that in VN.Grade C type lesions was significantly higher than that in VN.Grade A type lesions (P<0.05). The incidence of pit disorder or destruction (+) and (++) levels in VN.Grade B and C type lesions was significantly higher than that in VA type lesions (P<0.01), and that in VN.Grade C type lesions was significantly higher than that in VN.Grade A type lesions (P<0.01). The incidence of high grade carcinoma in VN.Grade B and C type lesions was significantly higher than that in VA type lesions (P<0.01), and that in VN.Grade C type lesions was significantly higher than that in VN.Grade A type lesions (P<0.05). These findings indicate that V type pit pattern subclassification, including our new subtype, is useful for predicting the detail invasion depth of early colorectal carcinoma. These V pit pattern subtypes are based on the degrees of desmoplastic reaction, pit disorder or destruction, and histologic grade of carcinoma.
Modelo de remodelación de callo óseo de fractura de fémur humano

El presente trabajo se embarca en la tarea de aplicar los modelos de remodelacion osea con la intencion de simular la evolucion de las propiedades mecanicas del tejido oseo de un hueso largo en formacion y/o reparacion, desde la aparicion del callo oseo tras una fractura hasta la total recuperacion de dichas propiedades. Y es aqui donde surge el otro gran objetivo de esta tesis: conocer las propiedades mecanicas del callo oseo. Esta tesis puede dividirse en dos grandes bloques: por un lado la obtencion de un modelo micromecanico para estimar las propiedades del callo oseo y por otro lado el desarrollo de modelos de remodelacion osea capaces de simular los procesos mecanicos y biologicos que se producen como consecuencia de la actividad remodelatoria. Los objetivos principales de esta tesis son: - Conocer la composicion y la estructura interna del callo oseo. - Desarrollar un modelo micromecanico capaz de estimar las propiedades mecanicas del callo oseo a partir de la composicion y estructura del mismo. - Adaptar y/o implementar numericamente los distintos modelos de remodelacion osea de los que se disponen. - Disenar e implementar mejoras a dichos modelos que permitan reproducir con mayor fidelidad los distintos procesos biologicos implicados. - Desarrollar un metodo que intente simular la adaptacion de la forma exterior del hueso en funcion de la carga a la que esta sometido (carga interna y/o externa) e implementarlo para su uso en simulaciones numericas. A esto se le conoce como remodelacion osea externa. - Realizar una simulacion del modelo de remodelacion del callo completo: estimar las propiedades del callo oseo utilizando el modelo micromecanico, incluir dichas propiedades en una malla de elementos finitos real del hueso + callo y simular la remodelacion osea interna y externa que se produce. El modelo micromecanico desarrollado, implementado y utilizado en esta tesis se basa en modelos de comportamiento de tejido cortical de otros autores. La modificacion de los mismos viene motivada por la propia microestructura del tejido fibroso: se trata de un tejido muy desorganizado compuesto por colageno y mineral que, a diferencia de tejidos maduros, no presenta una estructura tan jerarquizada. Para caracterizar el modelo ha sido necesario realizar una serie de ensayos experimentales sobre tejido oseo fibroso (callo oseo) y tejido oseo maduro de control (cortical). Sobre muestras de metatarsos de ovejas se ha determinado su contenido en agua (determinacion de humedad) y mineral (determinacion de la fraccion de cenizas). El modelo de remodelacion osea externa fenomenologico desarrollado se ha implementado para su uso junto con un modelo de remodelacion osea interna mecanobiologico previo. Conjuntamente, y utilizando las propiedades mecanicas obtenidas del modelo micromecanico del tejido fibroso, se han realizado una serie de simulaciones para modelar el proceso completo de remodelacion de un callo oseo de fractura de femur humano.
Cell wall-DNA association in Bacillus subtilis

Autolysis of cell walls of Bacillus subtilis 168 resulted in solubilization of wall-associated DNA. Most of the DNA was solubilized only in the later stages of autolysis. Solubilization of up to 70% of the wall by autolysins resulted in only 25 to 30% solubilization of wall-associated DNA. When the wall fragments remaining after 70% autolysis were analyzed by electron microscopy, it was observed that the preparations were highly enriched for completed septa, or poles. Partial autolysis at pH 5.2 or pH 8.6, both of which reflect hydrogen ion levels that permit either N-acetylglucosaminidase or N-acetylmuramyl-L-alanine amidase, but not both, to act, gave rise to enrichment of cell poles. When walls were incubated with subtilisin, DNase, or RNase, release of DNA (or DNA fragments) was accelerated. Density gradient centrifugation patterns of lysates of cells pulse-labeled with N-[3H]acetylglucosamine and then chased revealed that a small, but significant, proportion of the radioactivity sedimented to a density position equivalent to that of DNA-membrane complexes. Because the pulse-chase sequence enriched for radioactivity in cell poles, the results suggest that at least some molecules from polar cell walls have an affinity for DNA-membrane complexes. We suggest that DNA binds strongly, possibly via a DNA-membrane complex, to cell poles of B. subtilis. The results provide support for a view offered previously (Koch et al., FEMS Microbiol. Lett. 12:201-208, 1981) that some special structure in or very near the poles of gram-positive bacilli is involved in the segregation of DNA during cell division.
Trouser tear tests of two thin polymer films

Trouser tear testing has been concerned in this research work. A polypropylene film and a low density polyethylene film used in the packaging industry are considered. The experimental trouser tear tests showed different results for both materials when they were subjected to load in different material directions. Therefore the hypothesis was verified, that the in-plane material orientation/alignment induced during manufacturing, hence creating anisotropic in-plane mechanical properties, also affects the tearing behavior. A brittle-like failure was shown in the polypropylene film while the low density polyethylene presented a highly ductile behavior. The two polymer films can be classified as one low-extensible and one high-extensible material according to the test method utilized. Material parameters in the principal material directions i.e. manufacturing direction and cross direction were extracted from the experimental tests for further numerical studies. Scanning electron microscope was used for micromechanical and fractographical analysis of the crack tip and crack surfaces created during the tests. The methods discussed will help classify different groups of materials and can be used as a predictive tool for the crack initiation and crack propagation path in packaging material, especially thin polymer films.
Low-Cost Aperture-Coupled 60-GHz-Phased Array Antenna Package With Compact Matching Network

A low-cost multilayer antenna-in-package solution, using the standard printed-circuit-board (PCB) process, is proposed for the 60-GHz-phased array system. The design procedure focuses on overcoming the fabrication restrictions and realizing a low-cost, broadband, compact and reliable package solution. The multilayer stack-up structure consists of three laminates and two bondply layers, with which the antenna element, vertical quasi-coaxial via transition, antenna feedline, power, and low-speed interfaces are realized. An aperture-coupled patch antenna with a compact fan-shaped feeding network and a vertical quasi-coaxial via transition are proposed, fabricated, and measured. For the single antenna element, including the vertical quasi-coaxial via transition, the measured fractional impedance bandwidth (<inline-formula> <tex-math notation="LaTeX">$\vert \text{S}11\vert < -10$ </tex-math></inline-formula> dB) is 20.2%, and the measured peak gain is 6.9 dBi at 62 GHz. Based on the single antenna, a 16-element antenna package is realized in the dimension of 14 mm <inline-formula> <tex-math notation="LaTeX">$\times14$ </tex-math></inline-formula> mm <inline-formula> <tex-math notation="LaTeX">$\times0.925$ </tex-math></inline-formula> mm. Measurements show that each antenna element achieves a <inline-formula> <tex-math notation="LaTeX">$\vert \text{S}11\vert $ </tex-math></inline-formula> less than −10 dB from 57.2 to 64.5 GHz, 4–7.5 dBi gain across all four IEEE 802.15. 3c channels.
Electron microscopy of maize rough dwarf virus assembly sites in maize. Cytochemical and autoradiographic observations.

Summary The following experiments have been carried out: (1) enzymatic digestion with pronase and RNase, to study the nature of the cytoplasmic inclusions (viroplasm and cytoplasmic tubules) induced by the virus, and of the smaller virus particles as seen in the viroplasm; (2) autoradiographic experiments after [H3]-uridine incorporation, to detect the possible sites of virus synthesis and/or assembly. Enzymatic digestion of maize leaf tumours caused by maize rough dwarf virus (MRDV) showed that the viroplasm and cytoplasmic tubules induced by the virus are composed mainly of protein, and that the small particles embedded in the viroplasm are ‘naked’ RNA particles, since they were promptly digested by RNase, while the complete particles were not. Autoradiographic experiments demonstrated that [H3]-uridine was incorporated almost exclusively into the viroplasm containing virus RNA particles, while no incorporation was detected in the viroplasmic regions free of virus particles and in the mature virus particles as seen in the cytoplasm. It is concluded that the viroplasm is most probably the site of assembly of MRDV.
Individual Differences in Motivational Activation Influence Responses to Pictures of Taboo Products

In this article, the authors investigated responses to pictures of products whose use is socially or legally restricted for teens and young adults (e.g., beer, liquor, cigarettes). The authors theorized and found that these pictures are motivationally relevant and therefore elicit automatic activation in the appetitive/approach or aversive/defensive motivational systems, which leads to increased attention, arousal, emotional response, and memory for the risky products. The authors also found that these responses are mediated by individual differences in motivational reactivity. The authors suggest that placing images of these products in prevention messages may work against the prevention goal by increasing appetitive activation and positive emotion in populations more inclined to take risks.
Abomasal nematodes of small ruminants of Ogaden region, eastern Ethiopia : prevalence, worm burden and species composition

Une etude a ete mise en oeuvre afin de determiner la prevalence, les especes et la charge parasitaire en nematodes dans l'abomasum des petits ruminants de la region d'Ofgaden, abattus l'abattoir d'Elfora, agree pour l'exportation. Un total de 196 abomasum on ete examines selon des procedures standard (114 moutons et 82 chevres). Pour les especes d'Haemonchus, une prevalence generale de 91,2% et 82,9% a pu etre observee chez les moutons et les chevres respectivement. De meme, une prevalence de 37,7% et 40,2% a ete observee pour Trichostrongilus axei chez les moutons et les chevres, respectivement. Une difference statistiquement significative ( p <0,05) dans la prevalence et la charge parasitaire moyenne a pu etre notee en fonction de la periode de l'annee, et ce pour les deux nematodes de l'abomasum. La majorite des moutons et des chevres porteurs des formes adultes des parasites presentaient un degre modere d'infestation, seule une faible proportion des animaux etudies etaient fortement infestes. Les mâles adultes d'Haemonchus ont ete identifies comme H. contortus (95,1%), H. placei (3,4%) et H. longistipes (1,2%). De la meme facon, Le especes et leur proportions respectives sont similaires pour les caprins. Cette etude a mis en evidence la coexistence possible de 2 ou 3 especes d'Haemonchus chez un meme hote, suggerant que le passage possible du parasite a des hotes heterologues places sur les memes pâtures doit etre pris en consideration dans les strategies de controle de ces parasites.
Should epidemiologists be more sensitive to design sensitivity?

We would like to congratulate Zubizarreta et al for a carefully done nonexperimental study on the effects of the 2010 Chilean earthquake on posttraumatic stress. The article illustrates a compelling mix of complementary techniques to improve their nonexperimental study—clever design elements (broadly termed “design sensitivity”) to increase power and robustness, propensity score matching to adjust for observed confounders, and analysis of sensitivity to potential unobserved confounders. Using rare longitudinal data of persons before and after the earthquake to minimize recall bias and ensure appropriate temporal ordering, they compare persons with very disparate exposure to the earthquake and allow for heterogeneous treatment effects, finding that posttraumatic stress is “dramatically but unevenly elevated” among affected residents. Although there are many interesting aspects to the article, we focus here on the idea of design sensitivity because we believe it to be unfamiliar to most epidemiologists, with few examples in the applied literature. Design sensitivity can be thought of as a formalization of the general idea of using smart design elements to improve the validity of a nonexperimental study. Since the work of Campbell, Cornfield et al, Hill, and others, the assessment of threats to validity has played a central role in epidemiology and other applied sciences. Design sensitivity is a natural outgrowth of that earlier foundation. In particular, design sensitivity approaches aim to design studies that are less sensitive to unobserved confounding. Rosenbaum introduces and formalizes design sensitivity: “For a specific treatment effect and a specific research design with a large sample size, the design sensitivity asks the question of how much hidden bias would need to be present to render plausible the null hypothesis of no effect. The answer is a number, and it provides a quantitative comparison of alternative research designs. Other things being equal, we prefer the design that is less sensitive to hidden biases. ” Examples of potential design elements include assessing dose-response relationships and formalizing tests of multiple hypotheses (eg, multiple outcomes) within one study. In their use of design sensitivity, Zubizarreta et al compare people with particularly high versus low exposure to the earthquake and tailor the analysis to the theory that earthquakes may have “uncommon but dramatic” effects on posttraumatic stress. The particular test used to increase the design sensitivity in the analysis stage is Stephenson’s test, a variation of Wilcoxon’s signed-rank test, which allows for no effects on a subset of the sample but large effects on others. Using these two strategies results in an effect estimate that is highly insensitive to unobserved confounders. One benefit is that design sensitivity offers a formal way to incorporate qualitative information and beliefs about expected patterns of effects. For example, if researchers
