Specifying Shrinkage Limited Cement (Type SL)
Authors: Mohammadi J. , South W. 
Published: September 2016

Abstract
The Australian Standard AS 3972 specifies the maximum limit of 750 microstrain for the 28-day mortar drying shrinkage of samples prepared with shrinkage limited cement (Type SL). Although the current shrinkage limit is 750 microstrain, AS 3972 recommends a 600 microstrain for the maximum target or average of drying shrinkage of mortar samples. The lower recommended shrinkage level is justified in the Australian Standard by considering the inherent errors of the mortar drying shrinkage test method AS 2350.13, determined in 1997. The lower recommended shrinkage level is to provide a sufficient level of confidence that a single result obtained from different laboratories may not exceed the maximum limit of 750 microstrains. However, the “informative” recommendation of AS 3972 relating to the maximum average 600 microstrain shrinkage is considered a “normative” term by other specifiers in Australia such as road authorities and ATIC-SPEC SP-43. The current study investigated the past ten-years mortar drying shrinkage test results from round-robin proficiency programs of the major Australian laboratories to calculate the current inherent repeatability and reproducibility error of performing AS 2350.13 test. The average ten-year reproducibility error at 95 % confidence level was calculated 18.6 %, and therefore, it is recommended to increase the recommendation for the maximum average drying shrinkage guidance in Australian Standard AS 3972 Section A3.3.5 from 600 to 630 microstrain. Moreover, repeatability of test was calculated to be 6.3 %. This was equal to maximum of 44 microstrains for Type SL cement with maximum drying shrinkage of 750 microstrain. Results were compared with repeatability of other international test methods and some recommendations for improving the repeatability test procedure were provided for any future research in this area.
An Effective Preprocessor of Edge Detection for Distorted Images
Authors: Lee J.-S. 
Published: September 2016

Abstract
Edge detection is an intuitive strategy to figure out an object in digital images. Nevertheless, if an image is spread with noise such as ultrasonic noise, scanner noise, or camera noise, general edge detectors cannot perform effectively. In this paper, a preprocessor was provided to handle this issue. For each pixel in a speckle image, the preprocessor first determined whether it was noise or not. It then checked if it was located on an edge. According to the information, the preprocessor can define different weighted coefficients to equalize each pixel. After that, we can perform an edge detection mechanism on the processed image to draw the edge map. Experimental results showed that the preprocessor is able to effectively improve the performance of edge detection mechanism in speckle images.
Load-Separation Method, Spb, Used to Estimate Crack Extension for J-R Curves, Modified for Geometric Variations in Blunt-Notched Remaining Ligament
Authors: Wainstein J. , Perez Ipiña J. E. 
Published: September 2016

AbstractThe Spb method estimates stable crack growth in fracture mechanics precracked specimens test. It compares the load ratio between a precracked specimen that exhibits stable crack growth and a blunt-notched specimen with apparent constant crack length when tested at constant displacement. When it was applied to very tough material, it was found that blunt-notched remaining ligaments varied by as much as 11.83 %, affecting visibly the results. Therefore, to apply the Spb method to very tough material for which non-standard specimens could be used as coiled tubing, the methodology limits are investigated. In this work, particularly the effect of geometry changes through an incipient crack growth produced on the blunt-notched specimens for very tough materials is analyzed. Hence, a modified Spb method is presented that takes into account the change in geometry of the blunt-notched specimens. Results provided in this paper are quite encouraging.

Published: September 2016

Abstract
A new type of radial ultrasonic transducer was fabricated in this study. The performances of five radial ultrasonic transducers of different thickness were investigated in this paper. It was found that the radial ultrasonic transducers possess the greatest sensitivity when the matching layer thickness is 2.5 mm. The addition of tungsten powder in the backing layer could effectively absorb noise, which improved the acoustic attenuation performance of the backing layer and their sensitivity. To study the directivity, the ultrasonic transducer was put into water. It was found that the transducer could achieve transmitting ultrasound in all radial directions and the ultrasonic signal is similar along all radial directions, i.e., the transducer exhibits isotropic properties, which makes it a good candidate for nondestructive testing of concrete when embedded in concrete elements and structures.
Smooth versus Textured Surfaces: Feature-Based Category Selectivity in Human Visual Cortex
Authors: Echavarria Cesar , Nasr Shahin , Tootell Roger 
Published: September 2016

AbstractIn fMRI studies, human lateral occipital (LO) cortex is thought to respond selectively to images of objects, compared with nonobjects. However, it remains unresolved whether all objects evoke equivalent levels of activity in LO, and, if not, which image features produce stronger activation. Here, we used an unbiased parametric texture model to predict preferred versus nonpreferred stimuli in LO. Observation and psychophysical results showed that predicted preferred stimuli (both objects and nonobjects) had smooth (rather than textured) surfaces. These predictions were confirmed using fMRI, for objects and nonobjects. Similar preferences were also found in the fusiform face area (FFA). Consistent with this: (1) FFA and LO responded more strongly to nonfreckled (smooth) faces, compared with otherwise identical freckled (textured) faces; and (2) strong functional connections were found between LO and FFA. Thus, LO and FFA may be part of an information-processing stream distinguished by feature-based category selectivity (smooth > textured).

Published: September 2016

Resumo.Este trabalho tem como objetivo analisar o apego no contexto de institucionalização de crianças que construíram as suas infâncias no entorno das prisões, enquanto as mães cumpriram pena de reclusão em unidades do sistema prisional. A base teórica do tema proposto centra-se na abordagem culturalista, e social. A pesquisa desenvolvida durante o Doutorado em educação pretendeu responder à indagação: Como as crianças vivenciam a experiência do cárcere do pai e/ou mãe? Metodologicamente se define como uma pesquisa qualitativa, do tipo Estudo de Caso Etnográfico que permitiu o conhecimento dos significados e experiências culturais da infância através de uma descrição que apontou o sentido que as crianças dão a vida carcerária, como interpretam e estruturam, a partir desse sentido, o seu mundo. Foi constatado que o desenvolvimento de uma criança na penitenciária pode ser caracterizado por uma construção de apego em que a criança experimen ta ciclos de proteção e ao mesmo tempo de afastamento e consequentemente desproteção. As crianças vivenciam conflitos porque veem e sentem a situação de aprisionamento e punição do familiar, convivem num contexto de institucionalização no Abrigo e enfrentam a condição de pertencer a um grupo: filhos de presidiários.Palavras-chave: Infância. Apego. Sistema prisional.Abstract.This study aims to analyze the attachment in the context of institutionalization of children who have built their childhoods around prisons, while their mothers were in the prison system. The theoretical basis of the subject focuses on the culturalist and social approach. The research developed during the PhD in education aimed to answer the question: How do children, experience the imprisonment of their father and / or mother? Methodologically defined as a qualitative research and Ethnographic Case Study, it allowed to know the meanings and cultural experiences of childhood through a description that showed the meaning that children give to life in prision and how they interpret and build their world through this sense development of a child in prison can be characterizedby a construction of attachment where the child experiences cycles of protection and at the same time have distance and therefore unprotected feeling. Children experience conflicts because they see and feel the situation of imprisonment and punishment of the family, living in a context of institutionalization in shelter and face the fact of belonging to a group: children of prisoners.Keywords: Childhoods.

Abstract:The widespread use of the Internet has facilitated that young people become sexually active on the Internet. Some studies suggest that alcohol consumption or abuse of Internet are factors that influence the practice of cybersex. For this reason, we propose this work in order to explore the relationship between these variables and cybersex. Taking a sample of 127 students 14 years old, we have found that there is a deep relationship between Internet abuse, cybersex, and different aspects of alcohol consumption. From these results, we discuss important implications for the nosological status and general knowledge of Internet sex.Keywords: Cybersex, Internet addiction, Alcohol, teenagersResumen:El uso generalizado de Internet ha facilitado que cada vez sean más los jóvenes que inician su actividad sexual en Internet.

The aim of the study is to identify the specific characteristics of companies with state participation, relating to medium-sized companies, and their reflection during assessment of corporate governance quality in preparation for the long-term development programs for public companies, the share of the Russian Federation in the authorized capital in the aggregate more than fifty per cent. Actualization of the goal set in this publication is that the typical structure of corporate governance of large corporations is of little use for small and medium-sized companies because of their significant features. It occurs sort of collision: the corporate governance system in mid-sized companies can not be possesses a fundamental corporate governance of large corporations, but it should be oriented towards the development and improvement. After all, only the use of basic standards, elements and tools of traditional corporate governance systems allows to build robust governance structure to medium-sized businesses.The article discusses specific features of corporate governance and to assess its quality with regard to medium-sized companies with state participation. Spells out interests of stakeholders associated with the company. The problems of corporate governance in the midmarket companies with 100% state package are analyzed. We consider the practical experience of evaluating the quality of corporate governance for the purposes of long-term development of the company and strategic management. Consideration characteristics companies with state participation, belonging to medium-sized businesses, during of corporate governance quality assessment in them will expand methodological assessment base and can be used in the practice of taking effective managerial decisions.

Published: September 2016

Background: The aim of this study was to evaluate a new technique for treating dehiscence buccal bone sites (Class II) with immediate implant and collagen‐enriched bovine‐derived xenograft blocks without a surgical flap or membrane.Methods: Individuals with at least 5 mm of buccal bone dehiscence were selected for a flapless surgical approach to insert xenograft blocks into buccal dehiscence defects as well as the gap between implant and residual bone wall. No membrane was used. Buccal bone wall height was measured by computed tomography in the preoperative period (T0) and 6 to 12 months after procedure (T1). Likewise, buccal‐lingual width of alveolar ridge as well as thickness of buccal wall was compared with the contralateral tooth.Results: Fourteen patients were selected. Buccal wall height at T1 was not significantly different after 6 to 12 months between the treated and contralateral teeth, although both were greater than T0 (P <0.01). The heights ranged from 6.4 to 16.30 mm at T0, 12.8 to 25.6 mm at T1, and 14.8 to 25.29 mm in the contralateral teeth. Significant differences were observed between treated teeth (T1) and their contralateral, both buccal‐lingually in the alveolar ridge (P = 0.007) and in buccal wall thickness (P = 0.003). Wall thickness ranged from 0.9 mm to 3.81 mm at T1 and 0.25 mm to 1.60 mm in the contralateral teeth.Conclusion: Immediate implant placement at dehiscence buccal bone sites using flapless surgery combined with xenograft blocks provided complete formation of the buccal bone wall up to the implant shoulder.
