Authors: Deliiski Nencho , Brezin Veselin , Tumbarkova Natalia
Published: July 2015

A 1D mathematical model for the computation of the temperature on the surface of cylindrical logs, tsr, and the non-stationary temperature distribution along the radiuses of logs subjected to freezing and subsequent defrosting at convective exponentially changing boundary conditions has been suggested. The model includes mathematical descriptions of the thermal conductivity in radial direction, λr, the effective specific heat capacity, ce, and the density, ρ, of the non-frozen and frozen wood, and also of the heat transfer coefficient between the surrounding air environment and the radial direction of horizontally situated logs, αr. With the help of the model, computations have been carried out for the determination of αr, tsr, λsr, and 1D temperature distribution along the radiuses of beech logs with diameters of 0.24 m, initial temperature 20 °C, and moisture content 0.4 kg·kg-1, 0.8 kg·kg-1, and 1.2 kg·kg-1, during their freezing at -20 °C, and during subsequent thawing at 20 °C.
Differences in development levels of urban gminas in the Warmińsko-Mazurskie voivodship in view of the main components of sustainable development
Authors: Pawlewicz Katarzyna
Published: July 2015

The aim of this study was to evaluate various components of sustainable development (social, spatial-environmental, economic) in urban gminas (administrative region of the 3rd order in Poland) of the Warmińsko-Mazurskie voivodship (administrative region of the 1st order in Poland). The results were used to rank the analyzed gminas in terms of their sustainable development levels. The analysis was performed with the use of Hellwig’s composite measure of development. The results were used to determine the overall value of the composite measure, calculated as the median of composite measures for each of the three components of sustainable development. The above approach was used to rank gminas in view of their sustainable development levels.

Data for the analysis was supplied by the Local Data Bank of the Central Statistical Office and the Local Government Analysis System for 2010 covering 16 gminas in the Warmińsko-Mazurskie voivodship. The results of the analysis point to variations in the value of the main components of sustainable development in the evaluated urban gminas in the Warmińsko-Mazurskie voivodship.

Published: July 2015

Diatom composition of the rheoplankton (phytoplankton) in the Sajó-Hernád river system (Slovakia and Hungary) was studied. Forty two sample sites were designated on the watershed from source to mouth of the two rivers and their tributaries. Samples were taken in July 2012. Altogether, 258 diatom taxa were identified. The microflora was dominated by tychoplanktonic elements. According to the relative abundance of the occurring taxa, four groups could be distinguished. Differentiation of these groups was confirmed by differences in the habitat characteristics, viz. altitude, width of watercourse, macrophyte coverage and river bed material. Diversity of diatom taxa in the phytoplankton was also studied. A positive relationship was found between the macrophyte coverage and the Simpson and the Shannon indices. In contrast, a negative relationship was shown between the macrophyte coverage and Berger-Parker diversity, in which metric the role of the dominant taxa is emphasized. Although the phytoplankton in rhithral rivers is influenced by stochastic events, our results reveal that geographical and hydromorphological characteristics of the rivers and coverage of macrophytes can also play role in shaping the composition and diversity of the phytoplankton.
Planning Documents As an Element of Modernizing the Urban Structure of the Poznań Metropolitan Area/ Dokumenty Planistyczne Jako Element Modernizacji Struktury Urbanistycznej Poznańskiego Obszaru Metropolitalnego
Authors: Bonenberg Wojciech
Published: July 2015

The article presents a report on studies concerning the role of planning documents in the modernization process of the Poznań metropolitan area (PMA). Over the last 25 years, dynamic social, economic and spatial changes have taken place in this area, which is becoming an increasingly integrated place combining living, work and leisure for a million residents. Emerging challenges regarding the functional, spatial and infrastructural modernization of the PMA call for new planning methods. In this respect, the existing planning documents and methods by which they are prepared are not able to keep up with the ongoing changes and constitute an obstacle in the modernization of the metropolitan area. The purpose of the article is to identify the risks posed by the discrepancies of existing planning records. Recommendations aimed at adapting the planning documents to the challenges of modernizing the PMA have also been presented.
Modern-Day Public Space in the Historical Context of a City – New Development of the Cathedral Square (Domplatz) in Hamburg/ Współczesna Przestrzeń Publiczna W Hsitorycznym Kontekście Miasta – Nowe Zagospodarowanie Placu Katedralnego (Domplatz) W Hamburgu
Authors: Jóźwik Renata
Published: July 2015

The article presents the history of transforming one of the oldest places in Hamburg - the Cathedral Square (Domplatz), as well as the influence of historical factors on the conception behind its development. A tumultuous history, especially the consequences of World War II, has led to the diminishment of its historical significance. The undeveloped quarter once occupied by a prehistoric settlement and St. Mary's Cathedral functioned as an urban wasteland and a parking lot for a few decades. Attempts to change this state of things proved unsuccessful.

Currently, revitalization works aimed at renewing city centers are being realized more and more often, in order to make them become competitive against the overly developed suburbs and so as to return to the tradition of forming a European city. The green area established in the Cathedral Square in 2009 was to be built-up initially, but owing to the objection of urban communities - conservators, archeologists, politicians, as well as public opinion, such plans were abandoned. The proposed and realized current form of the square reflects the historical background of the city and honors the importance of the location. The article refers the described example to the Recommendation signed in 2011 by the UNESCO General Conference regarding Historic Urban Landscape.
Compact Dual-Band Proximity-Fed Circularly Polarized Patch Antenna for BDS Applications
Authors: Li Jianxing , He Bin , Fang Jing , Zhang Anxue
Published: July 2015

This paper presents a compact dual-band proximity-fed circularly polarized (CP) patch antenna for BeiDou Navigation Satellite System (BDS) operation at B1 (1,561 MHz) and B3 (1,268 MHz) bands. The antenna aperture is minimized down to 26.6 mm (λ/9 at the B3 band) in diameter and 12 mm (λ/20 at the B3 band) in thickness using high permittivity dielectric substrate and meandered slots. The antenna design features that the resonant frequency in the higher band could be tuned independently by adjusting the branch length and breadth without affecting the lower band. To achieve right-handed CP (RHCP) radiation property, quadrature phase feeding is employed together with a broadband 0°–90° hybrid utilizing a small surface mount LTCC hybrid coupler chip. Experimental results show that the RHCP gain maintains larger than 1.5 dBic and the axial ratio (AR) stays below 3 dB within the B1 and B3 bands. This antenna design is a promising candidate for small BDS arrays as well as other dual-band BDS applications.

Published: July 2015

Grain-size distribution has become in the last years an important indicator in the analysis of periglacial processes and landforms. However, as they exhibit a complex sedimentology, careful sampling is required to draw meaningful conclusions. The aim of the present study was therefore to validate the sampling procedure carried out on solifluction forms and to evaluate the effect of sampling pretreatment during grain size analysis. A comparison between multiple measurements of grain size distribution using the laser diffraction method (LDM) was performed on 54 sediment samples collected from different solifluction landforms at different depths in the alpine area of the Southern Carpathians. The results of parallel measurements were compared using textural and statistical indicators. The received distributions reinforced the properness of field sampling procedure in most of the cases. The results of textural classification and fractional composition showed a high consistency between the two parallel measurements made on untreated and pretreated samples. An overall fining as a matter of etching was identified. Relative deviation increased and correlation decreased as pretreatment advanced. HCl etching resulted a greater deviation and variability in case of the sand fraction, H2O2 rather affected the silt fraction. The greatest deviations were experienced in case of landforms developed on crystalline limestone. Pretreatment of samples introduced a major uncertainty to further comparison and interpretation. Thus, multiple LD measurements on a representative group of samples from the entire sample set were suggested before the geomorphological or environmental interpretation of results to decrease the uncertainties and to validate the processes

Authors: Capătă Adela
Published: July 2015

The purpose of this paper is to establish necessary and sufficient conditions for a point to be solution of a vector equilibrium problem with setvalued mappings and cone constraints. Using a separation theorem which involves the quasi-relative interior of a convex set, we obtain optimality conditions for solutions of the considered vector equilibrium problem. The main theorem recovers an earlier established result. Then, the results are applied to vector optimization problems and to Stampacchia vector variational inequalities with cone constraints.

Pyogenic granuloma (PG) also known as “eruptive hemangioma”, “granulation tissue-type hemangioma”, “

Before therapy, PGs of skin were initially rated in size and vascularization using color-coded duplex sonography. Usually the Nd:YAG laser (1064 nm) was employed. Laser settings and techniques were adjusted appropriately; i.e. pulsed, chopped or continuous wave for

In total, 450 patients with 454 PGs were treated between the years 2000–2013. The size of PGs at time of treatment was 2–15 mm. Forty percent of PGs showed former bleeding. Seventy-six percent (n=344) of PGs occurred during the first two decades of life; 60% of cases in this group (n=205) occurred during the first 5 years of age. Taken as a whole, no gender predominance (♂: 52%; ♀: 48%) was found. Interestingly in the first year of age there was a male predominance (♂: 61%); in contrary a female predominance (♀: 63%) in middle age was seen. Eighty percent of angiomas were located in the head-neck region, particularly on eyelids. In the years 2000–2004, 70% of cases were treated with the Nd:YAG laser; a single session was sufficient in 93% of this cases, and the recurrence rate was 7%. In contrast, in the years 2005–2013, Nd:YAG laser treatment was performed in 94% of cases with a recurrence rate of less than 4%. The most effective application mode was the use of the Nd:YAG bare fiber technique, for both coagulation

Laser treatment proved to be a successful method with no relevant side effects or complications. Scarring was observed in 40% of the cases (n=79) and thus less compared with shave excision and cautery. Hence, it can be suggested to include the Nd:YAG laser into the options of first-line therapy for PGs.
Mental Hygienic Aspects of Animal Assisted Education
Authors: Takács István , Szalai Katalin
Published: July 2015

The Institution for Special Education at the Faculty of Pedagogic of the University of Kaposvár has been engaged in animal assisted activities for about three years. Our most recent research program was conducted for over two month in the Spring of 2014 with the involvement of 66 children - all kindergarten and elementary school age -, 11 special educators, physicians, psychologists, special educators, teachers, ethologists. The primary focus of our research was the development (and examination) of memory however observations with ethological and mental hygiene angles were a natural segment of our work. A significant part of the observations pointed to factors that both the children and their educators have experienced: the acceptance of each-other, an increased level of tolerance, an increased attention level towards the partner (human and animal). The teachers gave account of their respective observations in a small conference at the end of the last school year. Researches were offered a glimpse into the unique world of the relationship between a part of “living nature” - the pygmy rabbit in our case - and humans. During the 12 sessions of the training our colleagues have made observations that could serve as basis for a new system of paradigms of animal assisted pedagogics in the future. Our experience can also be re-considered with aspects of remedial pedagogics: we are convinced that animal assistance can become an accentuated part of the care of children and students with impairments. This is also implied by the fact that preparatory works for the continuation of this research at a kindergarten and at a school are already in progress.
Materialistic Thinking and its Mental- Hygienic Implications among Students of Budapest Business School
Authors: Gombás Judit
Published: July 2015

Previous research with extrinsic (“materialistic”) and intrinsic (“non-materialistic”) life goals suggest that intrinsic aspirations (e.g. relationships, community service, personal development) are associated with a better functioning, mentally and physically more healthy personality. In this survey 198 undergraduate students of BBS were examined by the Aspiration Index questionnaire in order to determine the pattern of extrinsic and intrinsic life goals in their personality, to find relationship between personal background-factors and these aspirations, and to compare the attitudes of the young population to a less homogenous reference group. Compared with the reference group, young women of BBS find all goals more important, except for social commitment and general intrinsic aspiration. Both BBS female and male students were found more materialistic. The materialistic attitudes are significantly stronger among the students of business programs, but not among the students of humanities (andragogy). In conclusion, the students of BBS tend to accept more extrinsic life goals than members of the external reference group. These attitudes are influenced by the generational properties of this young population and by the educational program they attend (business or humanities). The extrinsic attitudes do not serve the individuals’ personal development or happiness; neither do they serve the interests of society. The new paradigms of the future business world are not yet interiorized.

Published: July 2015

Measurement of physical activity among patients with heart failure typically requires a special approach due to the patients’ physical status. Nowadays, a technology is already available that can measure the kinematic movements in 3-D by a pacemaker and implantable defibrillator giving an assessment on software. The telemetry data can be transmitted to a central system. The research aims to elaborate the methods that help to compare of the data concerning physical activity both built-in an accelerometer in Cardiac Resychrinisation Therapy (CRT) devices and data obtained from an external Actigraph GT3XE-Plus Triaxial Activity Monitor. 5 persons participated in the pilot study (n=5); mean age: 57+- 13.37; BMI: 90.6+- 7.63. The Actigraph data from CRT device were examined in a 6-day-interval, between February 28 and March 5, 2014. The investigation started conducting a 6-minute walking test and continued with the measurement of daily physical activity. For data analysis descriptive statistics and linear regression analysis were used. It is clear from the data obtained from Actigraph that the MET values (mean: 1.17 ± 0.096) of the patients in the sample were extremely low due to their disease. However, some patients with higher physical activity than average (1.26; 1.28) seemed to be noteworthy, but they showed lower performance than healthy people. The physical activity of the patients during the 6-minute walking test corresponded to 1.9-2.48 MET. The physical activity of patients was found typically in the “light or moderate range” classifying the physical activity by Actigraph. Data from Actigraph are accurate and detailed making the physical activity of the patients measurable and appreciable. The results of the 6-minute walking test were in the category from moderate to very vigorous for individualized moderate physical performance based on Actigraph. It indicates the individual performance differences among patients. However, the daily physical performance is even lower than that of the 6- minute walking. We can conclude from the data related to the percentage of the average activity in CRT system to the average energy consumption and the improvement in the patients’ physical condition. Due to the limitations of the sampling frequency the different time intervals cannot be isolated in the different intensity ranges. Therefore, the percentage of the data of physical activity provided by the device may have a limited use.

Death As a Legal Entity
Authors: Hirsh HL
Published: July 2015

Death is the inevitable concluding event of life. Though a physician and his associates struggle valiantly to alleviate pain and suffering, prolong life, and delay death, they are ultimately and invariably unsuccessful. Death is an event established by a medical diagnosis based on signs that are considered evidence of its occurrence. As our society has grown more complex and sophisticated, death also has legal implications, some of which are profound and complex in character.

Chlordiazepoxide and Alcohol: A Fatal Overdose
Authors: Rada RT , Kellner R , Buchanan JG
Published: July 2015

Chlordiazepoxide hydrochloride (Librium®) has been a safe and effective drug in the treatment of the acute effects of alcohol withdrawal [1] and has been a popular psychotropic agent in the treatment of chronic alcoholism because of its low incidence of side effects, low reported incidence of abuse leading to addiction, and wide margin of safety. Hollister [2] states that massive overdoses of the benzodiazepines offer little difficulty in management and concludes that the benzodiazepines are “virtually suicide-proof.” Davis et al [3,4] note that fatalities due to overdose of chlordiazepoxide alone have not been reported. In addition, there have been, to our knowledge, no reported fatalities with a combination of chlordiazepoxide and alcohol. The purpose of this paper is to report a fatal overdose in which a combination of chlordiazepoxide and ethanol was found. A second fatal overdose is presented in which chlordiazepoxide and ethanol were probably the only drugs taken.
Longevity Genes Revealed by Integrative Analysis of Isoform-Specific daf-16/FoxO Mutants of Caenorhabditis elegans

FoxO transcription factors promote longevity across taxa. How they do so is poorly understood. In the nematode Caenorhabditis elegans, the A- and F-isoforms of the FoxO transcription factor DAF-16 extend life span in the context of reduced DAF-2 insulin-like growth factor receptor (IGFR) signaling. To elucidate the mechanistic basis for DAF-16/FoxO-dependent life span extension, we performed an integrative analysis of isoform-specific daf-16/FoxO mutants. In contrast to previous studies suggesting that DAF-16F plays a more prominent role in life span control than DAF-16A, isoform-specific daf-16/FoxO mutant phenotypes and whole transcriptome profiling revealed a predominant role for DAF-16A over DAF-16F in life span control, stress resistance, and target gene regulation. Integration of these datasets enabled the prioritization of a subset of 92 DAF-16/FoxO target genes for functional interrogation. Among 29 genes tested, two DAF-16A-specific target genes significantly influenced longevity. A loss-of-function mutation in the conserved gene gst-20, which is induced by DAF-16A, reduced life span extension in the context of daf-2/IGFR RNAi without influencing longevity in animals subjected to control RNAi. Therefore, gst-20 promotes DAF-16/FoxO-dependent longevity. Conversely, a loss-of-function mutation in srr-4, a gene encoding a seven-transmembrane-domain receptor family member that is repressed by DAF-16A, extended life span in control animals, indicating that DAF-16/FoxO may extend life span at least in part by reducing srr-4 expression. Our discovery of new longevity genes underscores the efficacy of our integrative strategy while providing a general framework for identifying specific downstream gene regulatory events that contribute substantially to transcription factor functions. As FoxO transcription factors have conserved functions in promoting longevity and may be dysregulated in aging-related diseases, these findings promise to illuminate fundamental principles underlying aging in animals.
Shape Preferred Orientation (SPO) methodology for oriented hand specimens of rock and outcrops through digital image processing
Authors: Botero García Manuela , Marín López Sara Paulina , Vinasco Vallejo Javier
Published: July 2015

The shape-preferred orientation (SPO) is a technique, which allows the study of the fabric of deformed rocks and understanding its dominant deformational style and partitioning. This work presents SPO results and methodological aspects for one hand specimen of rock and a high-resolution composed image of an outcrop through digital image processing. The technique involves imaging of three semi-orthogonal oriented sections for digital processing and subsequent implementation in structural software. The image processing consists of digital separation of a phase of interest, i.e. defining the deformational fabric. The processed images are then implemented in the SPO2003® software for acquisition of sectional ellipses and finally implemented in the Ellipsoid2003® software to obtain the characteristic ellipsoid of deformational fabric. For outcrops, due to the difficulty to finding three appropriate sections for photography, it was only obtained a sectional ellipse, characteristic of the rock fabric based on contrasting deformed quartz segregates in mylonitic schists.
Geology of the southern part of Sabanalarga Batholith. Implications for terrane theory in the west of Colombia
Authors: Guiral Vega Juan Sebastian , Rincón-Gamero Jonathan José , Ordoñez-Carmona Oswaldo
Published: July 2015

The Colombian Andes are the product of the interaction of terranes with different geological affinity, such as the Western Cordillera, which is made up of blocks of oceanic affinity, that have been accreted to the western boundary of pre-existing terranes with continental affinity. The study area is geologically dominated by the Sabanalarga Batholith, which has at least two facies, gabro-diorite and tonalitie-granodiorite, that intrude the Barroso Formation. Both units have been affected strongly by regional faults generating large areas of mylonites closely related with hydrothermal alterations and mineralization occurrences. Due the clear intrusive relationship between the Sabanalarga Batholith and Barroso Formation, and due the Cauca-Almaguer fault cuts both units without separating them, it is suggested that the Terranes Theory must be reconsidered in this part of the country, because the Cauca-Almaguer fault do not correspond to the boundary between Calima Terrane and the terranes Arquía and Quebradagrande.

Authors: Caro Luis D. , Blandón Astrid , Molina Jorge M.
Published: July 2015

Vertical and lateral gas content variation associated within a coal seam and its relation to porosity and geology was researched. Several seams of high sub-bituminous and bituminous coal volatile C from Amaga formation were selected. Channel samples were taken and were subdivided into the different plies (lithotypes associations), performing proximal analysis; Petrographic (maceral counting and determining the vitrinite reflectance); furthermore desorption testing and porosity.The higher gas content was in intermediate plies. It was possible to identify that the gas content, and micropores and mesopores has a direct relationship; also, there is a direct relationship between the content of liptinites macerals and gas content. In some cases, these relationships were not clear, since there is influence of geological factors such as the presence of faults favor migration and degassing of the mantles studied.

Published: July 2015

Summary Introduction/objective: fast-tract surgery (FTS) has been rapidly embraced by surgeons as a mechanism for improving patient care and driving down complications and costs. The aim of this study was to determine if any improvement in outcomes occurred after FTS protocol for selective double portazygous disconnection with preserving vagus (SDPDPV) compared with non-FTS postoperative care. Methods: patients eligible for SDPDPV in the period January 2012-April 2014 were randomly selected for the FTS group or non-FTS group. A designed protocol was used in the FTS group with emphasis on an interdisciplinary approach. The non-FTS group was treated using previously established standard procedures. The number of postoperative complications, time of functional recovery and duration of hospital stay were recorded. Results: patients in the FTS group (n=59) and non-FTS group (n=57) did not differ in terms of preoperative data and operative details (p>0.05). The FTS procedure led to significantly better control and faster restoration of gastrointestinal functions, food tolerance, rehabilitation and hospital discharge (p<0.05). Postoperative complications, including nausea/vomiting, severe ascites, wound infection, urinary tract infection and pulmonary infection were all significantly lower in the FTS group (p<0.05). According to the postoperative morbidity classification used by Clavien, overall complications and grade I complications were both significantly lower in the FTS group compared with the non-FTS group (p<0.05). Conclusion: adopting the FTS protocol helped to recover gastrointestinal functions, to reduce frequency of postoperative complications and to reduce hospital stay. The FTS strategy is safe and effective in improving postoperative outcomes.

Published: July 2015

Currently a lot of bottles of polyethylene terephthalate (PET) are discarded into the environment. In order to reduce the disposal of this polymer in nature, this study aims to evaluate the mechanical behavior of a clayey soil mixed with fine crushed PET. The potential use of this waste material in geotechnical applications may ultimately reduce the problem of improper disposal and improve the strength and deformation characteristics of the soil. This paper presents an experimental study to evaluate the mechanical behavior of pure soil and mixtures with different contents of PET waste by triaxial tests, in order to obtain the strength parameters of the Soil-PET mixtures. The clayey soil used was mixed with 10 and 20 percent of fine crushed PET by dry weight. Characterization tests such as grain size, Atterberg limits and compaction test were performed on the soil-PET mixtures. Triaxial tests at confining stresses of 50, 150 and 300 kPa were done on the soil and mixtures. The results show that the soil strength parameters are influenced by the addition of the fine crushed PET, thus improving characteristics such as friction angle and cohesion of the Soil-PET mixtures. This improvement also depends on the confining level which the samples were submitted. These mixtures may be used in pavement and other geotechnical works, so this paper proposes to contribute to a better understanding and interpretation of the behavior of reinforced soil with waste PET.

O Estado de Santa Catarina sempre sofreu com desastres naturais, porém esse fato ganhou amplitude com os acontecimentos das enchentes de 2008, onde deslizamentos aconteceram em diversas regiões, causando mortes e prejuízos para toda a população. Entre todos os acontecimentos, um deles foi o escorregamento de parte do talude rodoviário do Morro do Boi no km-140 da rodovia BR-101 sentido sul. A rodovia ficou interditada nas suas três pistas de rolamento, causando problemas para quem precisava passar pelo local e prejuízos para todo o estado, pois esta é uma das mais importantes ligações da capital Florianópolis com o Vale do Itajaí e região norte do estado. É primordial que seja feito um estudo do talude rodoviário antes mesmo de sua implantação e de qualquer projeto relacionado a obras rodoviárias, a estabilidade e a segurança da rodovia é de grande importância e na maioria dos casos só é estudada depois que algum deslizamento acontece. Portanto, o objetivo principal desse estudo foi avaliar por meio de instrumentação geotécnica, a estabilidade do talude do km-140 da BR-101 no Morro do Boi localizado no município de Balneário Camboriú – SC. Para um conhecimento geotécnico da área em estudo, foram realizadas sondagens a percussão. Os dados dessas sondagens permitiram identificar uma camada de solo residual de migmatito com espessura da ordem de 3 m, representado por camadas silto-areno-argilosas. O estudo de análise da estabilidade indicou uma forte influência da posição do lençol freático no Fator de Segurança do talude, indicando que quando mais alto for o lençol freático, menor é o Fator de Segurança da encosta. Verificou-se a importância da análise da estabilidade, podendo assim entender como um talude chega a sua ruptura. Durante o monitoramento dos instrumentos, o comportamento do talude se mostrou estável, acima dos 1,50 preconizados por norma.

The great generation of urban solid has been a concern in several countries. This work presents a study with two materials: the asphalt binder oil residue accumulated in the bottom of asphalt tanks and the municipal solid waste ash, to be used, respectively, as a substitute of conventional binder in asphalt mixtures and for soil stabilization in pavements base layers. Were evaluated properties as the mechanical behavior of the mixtures through experimental tests. The results show the potential of incorporating these residues for low traffic roads, allowing the construction of low cost roads and an environmental use of the residue.
EMPREGO DE AGREGADOS RECICLADOS DE CONCRETO CARBONATADOS NA PRODUÇÃO DE NOVOS CONCRETOS
Authors: Fröhlich Jéssica , Hentges Tatiane Isabel , Kulakowski Marlova Piva
Published: July 2015

Muitos estudos sobre a substituição dos agregados convencionais pelos agregados reciclados de resíduos de concreto (ARC) na produção de novos concreto vêm sendo realizados. O emprego do ARC, por apresentar maior porosidade, demanda maior volume de água, aumentando a relação água/cimento destes novos concretos. O ARC exposto à carbonatação sofre uma alteração em sua microestrutura, podendo diminuir sua porosidade. Este trabalho objetiva verificar o comportamento de concretos com ARC carbonatado e não carbonatado, no estado fresco e no estado endurecido. Foram realizados ensaios de absorção nos agregados reciclados. Mediu-se o abatimento de tronco cone dos concretos e a resistência à compressão aos 7 dias e 28 dias. Observou-se uma diminuição da absorção de água no ARC carbonatado em relação ao não carbonatado. Os ensaios de resistência à compressão aos 7 e 28 dias não permitiram verificar diferenças significativas entre os concretos.

Published: July 2015

O artigo apresenta o estudo do comportamento tensão-deformação de um solo arenoso reforçado e não reforçado com fibras de polipropileno, através da realização de ensaios triaxiais drenados, com extensão axial. Busca-se estabelecer padrões de comportamento que possam explicar a influência da adição de fibras, relacionando-a com os parâmetros de resistência ao cisalhamento e deformação do solo quando submetidos a esforços de extensão. Ensaios triaxiais foram realizados em amostras compactadas a uma densidade relativa de 50%, com 0,5% de teor de fibra de 12 mm de comprimento e 0,03mm de diâmetro. Foram aplicadas tensões efetivas médias iniciais de 20 a 600 kPa. Observa-se uma taxa única de crescimento de resistência a partir do momento em que as fibras são mobilizadas, que independe das tensões efetivas iniciais e se apresenta de forma linear e constante para o solo reforçado. Os resultados foram satisfatórios para aplicação do solo reforçado em obras geotécnicas que estejam sujeitas a cargas de extensão.

Explicando la corrupción judicial en las cortes intermedias e inferiores de Chile, Perú y Ecuador
Authors: Basabe-Serrano Santiago
Published: July 2015

Este artículo identifica las principales variables que explican la corrupción judicial en jueces inferiores y cortes intermedias de Chile, Perú y Ecuador. Refinando la metodología existente para la medición de la corrupción judicial e incorporando variables endógenas y exógenas al modelo, se propone que la formación profesional de los jueces, el respeto a la carrera judicial y el grado de fragmentación del poder en la arena política explican diferentes grados de corrupción judicial. A través de un modelo comparativo diacrónico y sincrónico de Chile, Perú y Ecuador, el artículo también constata que diseños institucionales en los que existen mayores instancias de impugnación o un mayor número de procedimientos, suelen ser más proclives a pagos ilegítimos u otras formas de corrupción judicial.AbstractThis article identifies the main variables that explain judicial corruption in Chile, Peru, and Ecuador. Improving the current methodological strategies used to measure judicial corruption and incorporating endogenous and exogenous variables in the model, this article argues that legal training of the judges, respect for the judicial career, and the fragmentation of political power explain different degrees of judicial corruption. Through a comparative diachronic and synchronic research design of Chile, Peru and Ecuador, the article shows institutional designs with more legal steps will be more inclined to illegal payments or other types of judicial corruption.
Evaluation of Individual Competitiveness and the Relationship Between Competitiveness and Yield in Maize

Published: July 2015

Competition plays an important role in ecology and is also a common phenomenon in agricultural production. The objectives of this study were to (i) investigate the yield variability of maize (Zea mays L.) cultivars and populations in mixtures, (ii) evaluate the competitiveness of maize cultivars, and (iii) evaluate the relationship between competitiveness and grain yield. A 2‐yr (2012–2013) field experiment was conducted using the de Wit replacement series desSign. Two maize cultivars, Yedan13 (YD13) and Zhongdan909 (ZD909), were grown in seven different YD13/ZD909 combinations (0:6, 1:5, 1:2, 1:1, 2:1, 5:1, and 6:0) with a plant density of 67,500 plants ha−1. Yield variability was observed on individual plant and population levels in different mixtures of both maize cultivars. Grain and dry matter yield per plant for each cultivar and population level decreased as the proportion of YD13 increased, and grain yield per plant was always lowest for YD13. However, the relative yield (RY) of YD13 was higher than that of ZD909 in all mixtures. Analyses of competition indices (RY, aggressivity, and relative severity of competition) indicated that YD13 was more competitive than ZD909. These results demonstrated that maize cultivars differ in their competitiveness. In addition, enhanced competitive pressure was accompanied by a reduction in yield performance. These results suggest a negative relationship between maize competitiveness and grain yield.
Ward continuity in 2-normed spaces
Authors: Ersan Sibel , Çakalli Hüseyin
Published: July 2015

In this paper, we introduce and investigate the concept of ward continuity in
2-normed spaces. A function f defined on a 2-normed space (X,?.,.?) is
ward continuous if it preserves quasi-Cauchy sequences, where a sequence
(xn) of points in X is called quasi-Cauchy if limn?1 ??xn,z? = 0 for every
z ? X. Some other kinds of continuities are also introduced, and interesting
theorems are proved in 2-normed spaces.
Some extensions of coefficient problems for bi-univalent Ma-Minda starlike and convex functions
Authors: Xiong Liangpeng , Liu Xiaoli
Published: July 2015

Motivated by the works of H.M. Srivastava et al. [7], we introduce and
investigate two new general subclasses HT (?,?,?), h,pHT (?) of
bi-starlike and bi-convex of Ma-Minda type functions. Bounds on the first
two coefficients |a2| and |a3| for functions in HT (?,?,?), h,pHT (?)
are given. The results here generalize and improve the corresponding earlier
works done by Ali et al.[1] and Brannan et al.[2].
Wear load capacity of crossed helical gears with wheel made from sintered steel
Authors: Miltenovic A. , Nikolic V. , Banic M.
Published: July 2015

Crossed helical gears have an important position in power transmission.
Important advantages of the crossed helical gears are the small design, the
realization of high ratios in one stage, and the low noise characteristics.
The paper presents a theoretical and experimental research of mesh
efficiency, tooth friction coefficient and wear for a wheel of crossed
helical gears made of Fe1.5Cr0.2Mo sintered steel with sinter-hardening
treatment and without additional treatment. The calculation method is also
given for the determination of wear load capacity of the worm with a helical
gear made of Fe1.5Cr0.2Mo sintered steel with sinter-hardening treatment.
These results provide product developers with the first important clues for
indicators for calculation of the worm with a helical gear.

Published: July 2015

Objective: 

To compare two distalizing devices supported by palatal miniscrews, the MGBM System (MGBM) and the Distal Screw appliance (DS), in dental Class II patients.

Materials and Methods: 

Pretreatment (T1) and postdistalization (T2) lateral cephalograms of 53 Class II malocclusion subjects were examined. MGBM consisted of 29 patients (16 males, 13 females) with a mean pretreatment age of 12.3 ± 1.5 years; DS consisted of 24 patients (11 males, 13 females) with a mean pretreatment age of 11.3 ± 1.2 years. The mean distalization time was 6 ± 2 months for MGBM and 9 ± 2 months for DS. Initial and final measurements and treatment changes were compared by means of a Student’s t-test.

Results: 

Maxillary superimpositions showed that the maxillary first molar distalized an average of 5.5 mm in the MGBM and 3.2 mm in the DS between T1 and T2; distal molar tipping was greater in the MGBM (10.3°) than in the DS (3.0°). First premolar showed a mean mesial movement of 1.4 mm, with a mesial tipping of 4.4° in the MGBM; on the contrary, first premolar showed a distal movement of 2.2 mm, with a distal tipping of 6.2°, in the DS.

Conclusions: 

The MGBM system resulted in greater distal molar movement and less treatment time, resulting in more efficient movement than was associated with the DS; DS showed less molar tipping during distalization.
