Religious Practice and Attitudes towards Offenders  [PDF]
Lucas Marcelo Rodriguez, José Eduardo Moreno
Psychology (PSYCH) , 2013, DOI: 10.4236/psych.2013.48089
Abstract:

This ex post facto study aims to investigate the influence of religious practice on the types of reaction to situations of offence. A multivariate analysis of variance (MANOVA) was used to evaluate the relationship between religious practice and the attitudes towards offenders. The study was carried out with adolescents and young people of both sexes. The sample comprised 673 male and female, with an average age of 18.28 and standard desviation of 1.21. As regards the religion that they practiced: 555 were catholic (82.5%) 39 were evangelical (5.8%) and others 79 (11.7%). To assess the level of religious practice, a grid with items containing the frequency of religious practice was prepared, taking into account the person’s self perception. The second instrument used was the Attitudes Towards Offenders Questionnaire (ATOQ). This instrument consists of seven scales, grouped into three factors: passive, aggressive and prosocial behavior, corresponding to the different responses to situations of offence: submission, denial, vengeance, resentment, hostility, claim for an explanation and forgiveness. The result of MANOVA of the tree factors of ATOQ, according to religious practice (practitioner, occasional practitioner and not practitioner), stated a significant difference. When analyzing the contrasts we can see that practitioners are less aggressive with respect to occasional practitioners and non practitioners. As regards the prosocial factor, the only significant contrast is shown in practitioners, who have a higher average of prosocial attitudes compared to non-practitioners.

Abstract: The aim of our study was to evaluate functional alterations of the corpus cavernusum and its correlation with the lack of response to treatment with PDE5i in eugonadal patients with Type 2 Diabetes Mellitus and Erectile Dysfunction. In this prospective randomized study we included 157 patients. All were treated with 5 mg tadalafil daily and 100 mg sildenafil on demand and the response to treatment was assessed in 6 month by dividing them into 2 groups: G1: Good response. Significative improvement of erectile function according to IIEF-5, and G2: There was not an improvement with the treatment. At the end of the treatment we performed neurological and vascular studies to both groups. Also we performed CC-EMG in order to evaluate penile autonomic neuropathy. 82 patients were included in G1 and 75 in G2. The time evolution of the ED was 1.5 years for G1 and 5 years for G2. Average fasting glucose and glycosilated hemoglobin values were significantly higher in G2 than in G1. Also we observed significant differences in penile vascular parameters between both groups. Peripheral neuropathy parameters did not show differences between both groups. Cavernous smooth muscle electromyography showed asynchronous and asymetric potentials in G1 (minimal autonomic neuropathy) and denervation potentials in G2 characteristic of severe CC damage. It is concluded that vascular and autonomic alterations are causes of severe CC damage and lack of response to treatment with PDE5i in this population. Peripheral neuropathy is not part of this process.

Abstract: This paper presents the validation of a computational tool that serves to obtain continuous measurements of moving objects. The software uses techniques of computer vision, pattern recognition and optical flow, to enable tracking of objects in videos, generating data trajectory, velocity, acceleration and angular movement. The program was applied to track a ball around a simple pendulum. The methodology used to validate it, taking as a basis to compare the values measured by the program, as well as the theoretical values expected according to the model of a simple pendulum. The experiment is appropriate to the method because it was built within the limits of the linear harmonic oscillator and energy losses due to friction had been minimized, making it the most ideal possible. The results indicate that the tool is sensitive and accurate. Deviations of less than a millimeter to the extent of the trajectory, ensures the applicability of the software on physics, whether in research or in teaching topics.

Abstract: Novas formas institucionais para oferta de forma o continuada de professores têm se apresentado na Regi o Metropolitana de Campinas (RMC). Procuramos, com este artigo, compreender como se tem dado esse processo, considerando o contexto descentralizado das políticas públicas educacionais e os problemas de gest o pública brasileira e metropolitana. Investigando e analisando diversos índices da última década, como: evolu o do número de professores, investimento e matrículas nos diversos níveis da educa o básica e por instancia administrativa, pudemos verificar determinados aspectos e reflexos dessas políticas, principalmente quando se trata de novas formas de arranjos entre o público e o privado. Percebemos o aumento da participa o das diversas formas n o estatais, incluindo o mercado, na oferta de forma o continuada de professores e gest o educacional, entre outras formas n o menos relevantes. New institutional arrangements for the provisions of teachers continuous training has been performed in the Metropolitan Region of Campinas (RMC). In this article, we seek to understand how this process goes on, considerating the context for decentralized public policies and educational problems in Brazil and metropolitan governance. Investigating and examinating various indices of the lasted decade, like growth in the numbers of teachers, investments and enrollment at all levels of basic education and administrative level, we could verify certains aspects and consequences of these policies, especially when it comes to new forms of arrangements between public and private. It was noted the increased participation of various non-governmental forms, including the market in offering continuing education for teachers and educational administration as any other forms no less relevant to perform it.

Journal of Software Engineering and Applications (JSEA) , 2016, DOI: 10.4236/jsea.2016.95014
Abstract: Several conditions as driver imprudence, road conditions and obstacles are the main factors that will cause road accidents. The most important automotive industries are incorporating technology to reduce risk in vehicles. Their products are expensive and lack flexibility to incorporate new features. This work presented a first approach to increase vehicle safety based on regional features. A framework was implemented, incorporating lane analysis and obstacle detection through image processing. The framework was tested using image datasets and real captures with satisfactory results.
Behavior of Heavy Metals during the Agro-Industrial Wastes Gasification  [PDF]
Marcelo Echegaray, Marianela Costante, Alejandra Saffe, Carlos Palacios, Rosa Rodriguez
Open Journal of Metal (OJMetal) , 2013, DOI: 10.4236/ojmetal.2013.32A1001
Abstract:

The characterization analysis of three agro-industrial wastes was performed in order to study its thermal gasification. Some analyses such as determination of Ca, K and Mg concentration and determination of three representative toxic metals concentration Cd, Cr and Pb in all its oxidation states and the fundamental state, were carried out. The heavy metals concentration was also determined in the ashes obtained during the gasification process. The mobility of these elements was studied through three leaching tests. The behavior of heavy metals, sulfur and chlorine compounds, was predicted considering the presence of water vapor, syngas, Ca, Mg, K, Si, Al and other ash components. The heavy metals are not more concentrated in the gasification ash; these pollutants are released during this process. Ca, Mg and K presence in these residues would promote the pollutants retention. The ash of the studied waste can be disposed in controlled landfills or used in road construction, according to the obtained results during the leaching test DIN-DEV S4. The obtained results in the leaching test EPA 1311 TLCP classify these gasification ashes as no toxic waste.

PASSIOMA: Exploring Expressed Sequence Tags during Flower Development in Passiflora spp.
Lucas Cutri,Marcelo Carnier Dornelas
Comparative and Functional Genomics , 2012, DOI: 10.1155/2012/510549
Abstract: The genus Passiflora provides a remarkable example of floral complexity and diversity. The extreme variation of Passiflora flower morphologies allowed a wide range of interactions with pollinators to evolve. We used the analysis of expressed sequence tags (ESTs) as an approach for the characterization of genes expressed during Passiflora reproductive development. Analyzing the Passiflora floral EST database (named PASSIOMA), we found sequences showing significant sequence similarity to genes known to be involved in reproductive development such as MADS-box genes. Some of these sequences were studied using RT-PCR and in situ hybridization confirming their expression during Passiflora flower development. The detection of these novel sequences can contribute to the development of EST-based markers for important agronomic traits as well as to the establishment of genomic tools to study the naturally occurring floral diversity among Passiflora species.

Introduction The genus Passiflora comprises almost 600 species of vines, lianas, and small trees, and its diversity reaches a maximum in Central and South America [1, 2]. To the genus Passiflora belongs the passionfruit (Passiflora edulis Deg.) and other species producing ornamental flowers known collectively as “passionflowers.” Passionflowers are appreciated exactly due to a remarkable range of floral complexity and diversity. The flowers of Passiflora exhibits several unique floral features, including multiple series of brightly colored coronal filaments, diverse operculum morphology, an androgynophore, and elaborate floral nectary structures (Figure 1). The evolution of this extreme variation of flower morphologies is believed to be the result of interactions with a wide range of pollinators [2, 3]. Therefore, this genus is specially suited to any study on the evolution of pollination syndromes, especially those aiming to elucidate the molecular mechanisms underlying these adaptative steps. Figure 1: Longitudinal sections of Passiflora spp. flowers. (a) a large insect- (bumblebee) pollinated flower ( P. edulis); (b) a small insect- (wasp) pollinated flower ( P. suberosa); (c) a hummingbird-pollinated flower ( P. tulae); (d) a bat-pollinated flower ( P. setacea). co: corona; an: androgynophore; li: limen; op: operculum. Bars: (a), (c), and (d): 1?cm; (b): 0.2?cm. Accordingly, one of the major challenges of current plant biology is to understand the genetic basis and molecular mechanisms of all naturally occurring developmental variation. This analysis has begun to benefit from the ever growing number of

Abstract: objective: this study describes the bone transportation technique for partial bone defect, and shows clinical and radiological results of a series of patients treated by using this method. material and methods: nine patients with partial bone defect were treated (six tibia and three femur). every patient had infection and nonunion. the initial procedure was to stabilize the bone, followed by a partial corticotomy on the healthy bone adjacent to the defect, in order to create a fragment to be distracted. this fragment was fixed by olive wires, which were conected to the thread rod. we used fibula transport for tibial lateral defect in two patients. the latency time, speed and rhythm of distraction were the same as approved by ilizarov. results: infection and nonunion were resolved, and the bone gap was filled in all cases. the most frequent problems were skin infection at the pin site and hypotrophy. conclusion: the partial bone defect treated by parietal bone transport was an effective soluction for all patients with infection and nonunion, filling the gap in all cases.
Saline oscillator as a teaching experiment
Lama, Lucas S. del;Mulato, Marcelo;
Revista Brasileira de Ensino de Física , 2011, DOI: 10.1590/S1806-11172011000400010
Abstract: the saline oscillator consists of two aligned containers that are filled in by a pair of different solutions, exhibiting electrical potential oscillations when released. these oscillations occur due to a difference of mass density presented by the fluids and they cause varying ions flow, leading to electrical potential variations between both reservoirs. many biological systems can be understood by this model. in this work, the saline oscillator was investigated using copper sulfate, cuso4, and sodium chloride, nacl, solutions, changing parameters as the diameter and length of the capillary, diameter of the internal compartment and amount of unwanted ions in the main reservoir (distillated and deionized water). the system is shown to be very useful in undergraduate teaching classes.
