Fuzzy Pseudo Subalgebras and Ideals of Pseudo D-Algebras
Authors: Jun Young Bae , Ahn Sun Shin
Published: July 2015

The fuzzification of pseudo subalgebras/ideals in d-algebras and pseudo BCK-ideals is discussed. Several properties are investigated. Relations between fuzzy pseudo BCK-ideals and fuzzy pseudo d-ideals are established. Conditions for a fuzzy set to be a fuzzy pseudo BCK-ideal are considered. Using the notion of fuzzy points, a general form of fuzzy pseudo d-subalgebras is introduced, and several properties including their characterizations are investigated.
Five Curious Congruences Modulo p2

Published: July 2015

Let p ≥ 3 be a prime, and let qp(2) := (2P 1 - 1)/p be the Fermat quotient of p to base 2. In this note, we prove that

.

As an application, using two combinatorial identities due to T. B. Staver in 1947 and G. Galperin and H. Gauchman in 2004, we obtain four curious combinatorial congruences modulo p2. As an auxiliary result, here we present an elementary proof of a congruence established by E. Lehmer in 1938. Notice that this con­gruence together with some other congruences given in our lemmas leads to the elementary proof of a beautiful Morley’s congruence due to F. Morley in 1895.
On Properties of Entire Solutions of Difference Equations and Difference Polynomials
Authors: Qi Xiaoguang , Cao Yinhong , Liu Yong
Published: July 2015

In this paper, we consider the existence of entire solutions of certain type of non-linear difference equation of the form: f(z)n + p(z)f(z + c)m = q(z). We also consider value distribution problems of difference polynomials of entire functions such as f(z)n(f(z)−1)f(z +c) for n = 1, which is a supplement of previous results.
Global Dynamics of a Delayed n + m-Species Competition Predator-Prey System on Time Scales
Authors: Wang Dongshu
Published: July 2015

In this paper, we consider a delayed n + m-species competition predator-prey system on time scales with Holling III functional response and multiple exploited (or harvesting) terms. By using the continuation theorem based on Gaines and Mawhin’s coincidence degree theory, easily verifiable criteria are established for global existence of multiple positive periodic solutions for the above system.
Comparison Of (G′/G)-Methods for Finding Exact Solutions of the Drinfeld-Sokolov System
Authors: Daghan Durmus , Yildiz Ozlem , Toros Serkan
Published: July 2015

Nonlinear Drinfeld-Sokolov system is studied analytically by using four different methods ((G′/G)-expansion, direct algebraic, different form of the (G′/G)-expansion methods, and direct integration) and the results are found numerically. New exact and numeric solutions are given and the comparison of the results obtained from these different methods, methods themselves and numerical results are discussed in detail. It is found that the (G′/G)-expansion and different form of the (G′/G)-expansion methods are really coincide and effective methods in the view of finding different solutions that cannot be obtained by using the direct integration for Drinfel-Sokolov system.
Classification of the Blaschke Isoparametric Hypersurfaces in Lorentzian Space Forms
Authors: Zhang Fengyun , Sun Huafei
Published: July 2015

In this paper, we study regular immersed hypersurfaces in Lorentzian space forms with a conformal metric, a conformal second fundamental form, the conformal Blaschke tensor and a conformal form, which are invariants under the conformal transformation group. We classify all the immersed hypersurfaces in Lorentzian space forms with two distinct constant Blaschke eigenvalues and vanishing conformal form.

For a definition of the theoretical fundament parts of the theory of fiscal federalism are used. Subsequently five hypotheses are put forward that are verified using the method of benchmarking. The theoretical conclusions and recommendations may be used for a more effective implementation of public policies within the surveyed countries.
Biodegradation study of bio-corn flour filled low density polyethylene composites assessed by natural soil
Authors: Sahi Samira , Djidjelli Hocine , Boukerrou Amar
Published: July 2015

This paper illustrates the aim to introduce biodegradable vegetable filler in synthetic polymers to prepare novel biodegradable composites. Low density polyethylene/alkali treated corn flour (LDPE/ATCF) composites were prepared by reactive extrusion using a twin-screw extruder. The microstructure, thermal properties and tensile properties were evaluated and compared with virgin LDPE. The Fourier transform infrared (FTIR) spectra showed a decrease in the hydrophilic nature of corn flour (CF) after alkali treatment. Scanning electron microscopy (SEM) micrographs showed good dispersion between matrix and filler. The tensile and elongation at break decreased by increasing the filler content in the composites. However, the Young’s modulus increased with the increase in filler content. The biodegradation of composites was studied in the environment using the soil burial test for 6 months. Differential scanning calorimetry (DSC) analysis showed an increase of the melting enthalpy (ΔHm) and crystallinity of LDPE with evidence of degradation. The biodegradability of the composites was enhanced with increasing ATCF content in the matrix. This result was supported by weight loss and degraded surface of composites observed through morphological studies. From the results, we conclude that the use of ATCF as filler in LDPE reduces pollution problems. This is advantageous for both the economy and the environment.

Published: July 2015

It is an old pursuit to find the balance between nature and society (within the individual and the sum of people). In order to talk about a healthy society, it is necessarry to have the people making up the society healthy too. The health condition of the individuals affects the society, creating a close connection amoing individuals and society. Health, mental and physical well-beings of members of society affects the economy, since a healthy workforce leads to developing economy, which hence can provide the requirements and conditions that ensure a mentally and physically healthy way of living for the society. Sport, everyday exercise, therefore regular training can also play an important social role, and can greatly contribute to social well-being. Decreased physical activity, sitting lifestyle are both specific traits of economically developed countres, and turns into a more and more threatening public health problem world-wide, which contribute to the development or aggravation of such chronic diseases and health damages, like morbid obesity, heart diseases, diabetes, hypertension, locomotor diseases, malignant tumors, depression. The topic of our research is related to mainly the subject of primary school healthcare programs. The measurements have been taken in 12 different educational institutions, which included primary, secondary, vocational schools, and a 6-grade school. The actuality of the topic is proven by the increased obesity appearing at more younger ages, and we intend to shed some light on the fact, that with a good healhcare strategy and short-term goals we can achieve positive results shortly on the fields of school healthcare.
Credibility and Accountability in Academic Discourse: Increasing the Awareness of Ghanaian Graduate Students
Authors: Adika Gordon S. K.
Published: July 2015

Drawing from a social constructionist perspective to written scholarly communication, this paper argues that training in academic writing for students in higher education especially in second language contexts should go beyond emphasis on grammatical correctness and paragraphing strategies, and also focus on the rhetorical character of academic discourse together with the mastery of its communicative protocols. Using the University of Ghana as a reference point, the paper reviews a selection of Ghanaian graduate students’ awareness of the protocols that govern academic discourses in scholarly writing, and in consideration of their unique educational and socio-cultural circumstances, the paper proposes strategies, from the pedagogical and institutional standpoints, aimed at increasing students’ awareness of the relevant communicative practices that engender credibility and accountability.
The Forced Sale of Real - Estate Property Aspects Regarding Procedure and Private International Law
Authors: Cret Daniela Cristina , Berlingher Remus Daniel
Published: July 2015

Indirectly enforcement is regulated by the Code of Procedure, as a form of enforcement, seeks the recovery of the creditor’s claim through valorization of the debtor’s property or the seizure of income that it has to receive from a third party. Collection action on real estate as a form of indirect civil enforcement is made by the forced sale of immovable property belonging to the pursued debtor, so that the pursuing creditor would cover the claim. In this scientific approach we will examine the issues of pre-sale formalities, the sale and auctioning of real estate property and adjudicating the real-estate property in the regulation of the Code of Civil Procedure, which came into force in February 2013, as well as in the provisions of private international law incidental in the matter.

Standard-Setters Versus Big4 Opinion, Concerning Iasb Revision Project of the Conceptual Framework for Financial Reporting. the Case of Presentation and Disclosures Chapter
Authors: Burca Valentin , Mates Dorel , Puscas Adriana
Published: July 2015

On the last decades the accounting system haven‘t been able to follow the dynamics of the economic systems generated by the globalization process. In order to reduce the lag between the demand of financial information and the offer of financial information, IASB has started numerous initiatives aiming the increase on the quality of the financial information. Among the current list of current IASB major projects there is also the project of revising the actual conceptual framework for financial reporting. This study is designed to give some directions that will be considered on the exposure draft of this project, analyzing the comment letters submitted by the members of ASAF and the Big4 as well. The study reveals the increasing importance the preparers and users give to the disclosures included on the notes to the primary financial statements. Moreover, on this study we emphasize several challenges that IASB has to face on issuing the exposure draft for this important project. Some of the main challenges refer to the narrow scope of the financial statements, the criteria used on classification, aggregation and offsetting, or the use of the materiality concept
A Simple, Rapid 125I Radioimmunoassay for the Detection of Barbiturates in Biological Fluids
Authors: Cleeland R , Davis R , Heveran J , Grunberg E
Published: July 2015

A radioimmunoassay using a 3H- or 125I-labeled morphine antigen has been shown to be of practical value for the rapid detection of nanogram amounts of morphine and morphine analogs in biological fluids [1–3]. A radioimmunoassay for detection of barbiturates by conjugation of a secobarbital derivative to protein was also developed utilizing 14C-labeled pentobarbital or barbital [4,5]. The present report describes our experiences with a practical radioimmunoassay for barbiturates employing a secobarbital derivative labeled with 125I, as the antigen.

Published: July 2015

The outdoor rock concert has been well established as an important feature in the life of young people both in this country and abroad. The frequent use of psychoactive chemicals at these large gatherings is to be anticipated, as shown by evaluations of such events in the past [1–3]. This phenomenon is concurrent with prevailing permissive attitudes of youth toward drug usage in our society. The evolution of the use of psychoactive drugs, especially the psychedelics, has been associated with the popularity of rock music.

The technique of physical comparison of fragments of glass by the characteristics of their edges or cross sections is well established. As successful as this technique can be, one is still occasionally faced with fragments, the edges of which cannot be fitted. Even though these fragments may have the same physical characteristics, identifications and exclusions are both impossible.
Firearm Residue Detection by Instrumental Neutron Activation Analysis
Authors: Rudzitis E , Wahlgren M
Published: July 2015

The neutron activation technique for firearm residue detection [1] is well known but not extensively applied. Additional work utilizing an optimized firearm residue detection technique by neutron activation analysis (NAA) [2] it made it clear that postirradiation radiochemical separations are the cause of several limitations which discourage a more general use of neutron activation analysis. The inherent time limitation due to 87-min half-life of 139Ba necessitates fast manipulations of radioactive solutions, which in turn requires an experienced radiochemist. In addition, there is an ever-present danger of overexposure and contamination. Besides, typically only a dozen samples can be irradiated per batch, which makes the method quite expensive. The developed statistical treatment bivariate-normal analysis [3] is inconvenient for routine applications. With this in mind, a method was developed which: (1) eliminates postirradiation radiochemistry and thus maximizes time for analysis, (2) accommodates over 100 samples per irradiation capsule (rabbit); (3) does not require a collection of occupational hand blanks, and (4) utilizes a simplified statistical concept based on natural antimony (Sb) and barium (Ba) levels on hands for the interpretation of data [4].
A Portable Explosives Identification Kit for Field Use
Authors: Fisco W
Published: July 2015

Throughout the years, field analysis of explosives has often been a subject of interest and previous work at Picatinny Arsenal has led to the development of field kits for the qualitative analysis of explosives. Because the methods described in reports [1,2] utilize wet chemical reactions, they are not readily portable because of the bulky nature of the reagents involved. Furthermore, interpretation of the color reactions involved requires, in the least ambiguous cases, a degree of technical competence not readily acquired by personnel conducting field analyses. When sample specimens are limited in quantity, the application of a destructive method of identification may preclude the conducting of required specific identifications. Although Jenkins and Yallop [3] and Hansson [4] used conventional thin-layer chromatography (TLC) to generate useful chromatographic information, the method was, nevertheless, destructive by the application of visualization sprays resulting in color reactions.
Human or Not? A Problem in Skeletal Identification

Published: July 2015

Physical anthropologists are frequently called upon by both the general public or law enforcement agencies to identify bones. This is particularly true in a desert region where people while exploring, rock-hunting, or hiking find a “bone” and bring it to the local university or museum for identification.
Is the Insanity Defense “Unconscionable”?
Authors: Perr IN
Published: July 2015

Over the years, much criticism has been directed at the concept of the insanity defense, which at its root reflected the traditional feeling that public policy is not served by imposing blame on those not responsible for their behavior. Though this principle has achieved a global recognition, it has reached its height in the Anglo-Saxon world of demons and devils, which is dominated by its early religious origins and the Augustinian concept of free will. Yet increasingly we have slowly become aware of other issues; for example, the rigid concept of responsibility and its corollary, nonresponsibility, have at various times been utilized to deprive various groups of power and participation in society. Traditionally, one group of disabled and legally incompetent who must be both protected and kept powerless consisted of the unholy triumvirate of the insane, children, and women.

A Photoluminescence Technique for Detection of Gunshot Residue
Authors: Jones PF , Nesbitt RS
Published: July 2015

When a suspect has been apprehended following a shooting, detection of gunshot residue on his hands may provide significant evidence in the investigation. The determination of the firing distance (distance from weapon to target) by the distribution of gunshot residue around a bullet hole is also useful in various gunshot investigations. We describe here the results of a preliminary study of the application of photoluminescence techniques to gunshot residue detection. The key objective in this study was to develop a rapid, reliable, and convenient method of detection for use in the crime laboratory.
Tool Marks in Bones and Cartilage
Authors: Bonte W
Published: July 2015

Tool mark examinations hold an eminent place in criminal routine work. Since the fundamental treatises of Kockel [1–3], the examination technique has continually been improved and extended to numerous methods of criminal investigation. Thomas [4] has given a fascinating survey of this development and has listed a series of notable authors. Further important publications are those by Mezger et al [5], Burd and Kirk [6], Burd and Greene [7–9], Flynn [10], Biasotti [11], Burd and Gilmore [12], Rees and Cundy [13], and, in German publications, by Mezger et al [14,15], Nippe [16], Specht [17,18], Bessemans [19], Angermayer et al [20], Winkler [21], Katona [22], and Hantsche and Schwarz [23].
Blood and Semen Stains on Outer Clothing and Shoes not Related to Crime: Report of a Survey Using Presumptive Tests
Authors: Owen GW , Smalldon KW
Published: July 2015

In many crimes blood and semen stains play an important part in the conclusions that a forensic scientist will present in court as evidence. There is, however, an absence of data relating to the frequency of occurrence of blood and semen stains on clothing unrelated to crime. This was discussed by Tryhorn [1], who said: One need only consider the frequency with which evidence regarding blood and semen stains is produced in court, to realise the need for data relating to the relative frequency of occurrence of such stains on garments in no wise related to crimes; for example, on one hundred garments chosen at random from miscellaneous sources, how many would show blood stains, how many semen stains? Questions such as these must arise in court, and answers based on experimental investigation would prove of considerable value in assessing evidence of this type.
Stability of Aqueous Ethanol Solutions Stored in Glass Ampules
Authors: Pella PA , Diamondstone BI
Published: July 2015

During our work on the development of performance standards for breath alcohol analyzers [1], it was necessary to prepare known concentrations of ethanol in distilled water for the purpose of measuring the performance capabilities of such instruments. In these studies we were concerned with the preservation of our reference ethanol solutions. For this reason we prepared a solution of known ethanol concentration and stored it in a number of flame-sealed, glass ampules. Some questions have been raised concerning the stability of ethanol solutions when stored in this manner [2]. We have measured the ethanol concentration by dichromate oxidimetry over a period of two years, and the results are reported in this paper.
Identification of Street Drugs by Thin-Layer Chromatography and a Single Visualization Reagent
Authors: Vinson JA , Hooyman JE , Ward CE
Published: July 2015

A number of reports on the use of thin-layer chromatography (TLC) in the analysis of street drugs have appeared [1–3]. Colors with various visualization agents applied in sequence are used for identification in conjunction with Rf values, spot tests [4], and crystal tests [5]. This paper reports the use of a rapid TLC screening procedure that utilizes a single developing solvent and a single visualization reagent, N,2,6-trichloro-p-benzoquinone imine (TCBI), for the preliminary identification of the drugs of abuse. In addition, other TLC developing solvents are outlined that can be used for further confirmation.

Published: July 2015

The use of internal standards in solutions analyzed by gas chromatography (GC) has become a routine system for simultaneous quantitative and qualitative analysis. Selection of a suitable internal standard has depended upon the following: (1) elution time must not significantly overlap the elution time of drug assayed, and preferably elute later; (2) the detector response must be linear over a wide range of concentrations; (3) a stock solution should be stable for a considerable period of time; and (4) the preparation and synthesis of internal standard should be rapid or the standard should be commercially available.

All areas of forensic pathology are covered and illustrated at the gross level.
A Review of “Methoden der Geschlechts-, Körperlängen- und Lebensalterbestimmung von Skeletfunden”
Authors: Kerley ER
Published: July 2015

This paperback volume will be of interest to those engaged in forensic anthropology or osteological research who can read at least some German. As the title states, it deals with the determination of sex, stature, and age from skeletal findings, and it is limited to these topics in skeletal identification. Basically, it is quite a useful compilation of references to the various methods that have been described for making such estimates and determinations, with brief descriptions of most of the methods cited. It is much more than a simple annotated bibliography, but could not be used as a handbook. The selection and arrangement of the references cited make them quite accessible in this new reference work.
Prostatic Acid Phosphatase Activity in the Postcoital Vagina
Authors: McCloskey KL , Muscillo GC , Noordewier B
Published: July 2015

The criminal offense of rape has been defined in various ways by both legal and medical authorities [1ߝ4]. There appears to be general agreement that two requirements are essential for establishing the crime of rape: (1) the lack of consent of the alleged victim and (2) carnal knowledge (constituted by even the slightest penetration by the male organ). Because circumstantial evidence alone may be inadequate for proof, the physician and the forensic scientist are required to assume major roles in supplying objective information in cases of this kind. They can be called upon to furnish evidence pertaining to the above requirements. The physician assesses and describes whatever injuries and medical evidence there may be. The forensic scientist is typically concerned with demonstrating the presence of seminal fluid in locations that would indicate recent sexual activity.
An Unusual Case of Pseudo Rape
Authors: Schiff AF
Published: July 2015

There are very few people who do not regard rape as a particularly brutal, heinous, and savage crime, far removed from the usual crimes of auto theft, burglary, grand larceny, shoplifting, and even murder, and deserving the most severe penalty the law can offer. On the other hand, there are even fewer people who do not view a man falsely and maliciously accused of rape with amazement, horror, pity, and a “There but for the grace of God go I” attitude.
An Improved Density Gradient System for Forensic Science Soil Studies
Authors: Nute HD
Published: July 2015

The density of a homogenous material is one of the more useful of its properties. Being dependent on the nature and composition of the material, it can be used as both a point of identification of the substance and a comparison of its composition with similar substances; being constant, affected only by temperature, it is reproducible. Techniques and equipment exist to easily and precisely measure the density of most liquids and solids. The basic techniques and applications of density measurements in the field of forensic science are covered by Kirk [1,2].
Enzymatic Characterization of Soil Evidence
Authors: Thornton JI , McLaren AD
Published: July 2015

Soils is most assuredly an important type of physical evidence; if one can establish that soil on the shoes or clothing of a suspect matches that of a crime scene it will lend support to a hypothesis that the suspect had, in fact, visited the scene. Likewise, comparison of soil from the tires or the undercarriage of an automobile with the soil from a particular location may establish with greater or lesser certainty that the automobile was at one time present at the location. Furthermore, soil evidence is more likely to be encountered in those offenses against persons or property which society deems most severe. Equally important is that soil evidence, properly examined and properly interpreted, may serve an exclusionary purpose and exonerate the innocent. Erratum to this paper appears in 21(2).
A Review of “Anaesthetics, Resuscitation and Intensive Care: A Textbook for Students and Residents”
Authors: Roaf ER , Gibbs RF
Published: July 2015

Somewhat less than 300 pages long, this small, paper-covered book is intended for medical students and “housemen”. First written in 1965, this popular British anesthesia text is now in its fourth edition. Although well written and cleanly illustrated, the book attempts to deal with altogether too much material in too few pages to be anything but an introduction. The charts, pictures, and line drawings are frequently used to great advantage and are clearly the book's finest feature.
Petrography, geochemistry and age of Cerro Frontino Gabro
Authors: Rodríguez-García Gabriel , Bermúdez-Cordero Jose Gilberto
Published: July 2015

The Gabro de Cerro Frontino was emplaced in the Cañasgordas Block, located in the Northern Segment of the Colombian Western Cordillera. It corresponds to a pluton composed of at least three magmatic pulses, emplaced during a short period of time. Gabbros and diorites are more common in the unit than clinopiroxenites, monzodiorites and monzonites. These rocks are composed of calcic to intermediate plagioclase, augite-egerine type clinopyroxene and biotite; olivine and flogopite may be present in some mafic rocks and alkali feldspar and quartz may be present in some felsic rocks. Sphene, magnetite and apatite are common accessory minerals. The silica content in the rocks varies between 37.08% and 54.4%, with constant values of MnO (0.1% 0.4%), impoverishment of Fe2O3, MgO, CaO, TiO2 and P2O5 as SiO2 increases, and enrichment of K2O, Na2O and Al2O3 as SiO2 increases. The basic and ultrabasic rocks fall in the sub-alkaline series, the rest of the samples fall in the medium to K-rich calc-alkaline series and in the shoshonitic series. The Gabro de Cerro Frontinocorresponds to magmas impoverished on heavy rare earth elements with respect to light rare earth elements, which suggests the contribution of a subduction component in the magma genesis. The LILE (Sr, K, Rb, Pb, Ba) are enriched with respect to the HFSE values that are relatively flat and impoverished; the unit also exhibits a negative anomaly of Nb with respect to Th and Ce, being a magmatic arc the environment of generation. The ages obtained in biotite using the Ar-Ar method fall between 9.87±0.18 Ma and 11.44±0.36 Ma, Middle to upper Miocene (Tortonian-Serravallian), similar to age of other plutons that are part of the Botón Arc.

Published: July 2015

The process of precipitated variation of a soil volume when subjected to increase in stresses which withstand and/or the degree of saturation, it's also known as collapse. Collapse Potential of soils can be determined from correlations derivative of the material properties index. That's why in this work, it was evaluated using different methods the Collapse Potential of soils for ten specimens of tropical residual soils coming from five different points in Aburrá and San Nicolás Valleys, and the results were compared with the index collapse obtained using the duple-oedometer test. It was achieved to establish which of the procedures is closer to the traditional test results, and thereby obtain an approximation to the potential collapse using easy implementation methodologies with significant costs savings and rehearsal times, without loss of reliability evaluation.

Um estudo sobre a distribuição das transferências para o setor de saúde no Brasil
Authors: Simão Juliana Barby , Orellano Veronica Ines Fernandez
Published: July 2015

Resumo Este trabalho investiga a existência de uma relação positiva entre receita municipal per capita - que inclui arrecadação local de impostos e transferências intergovernamentais incondicionais - e o recebimento de recursos através do Sistema Único de Saúde (SUS) pelos municípios brasileiros. Considerando o aspecto redistributivo, essa relação não seria desejável, já que municípios com maior capacidade de financiamento receberiam mais repasses por habitante destinados à saúde. Foram estimados modelos de painel com efeitos fixos, utilizando dados dos municípios brasileiros no período 2002-2010, obtidos em sua maioria através do Departamento de Informações do SUS (DATASUS) e do Sistema de Informações sobre Orçamentos Públicos em Saúde (SIOPS). Os resultados apontam que a receita municipal exerce, de fato, um impacto positivo inesperado sobre o recebimento de transferências do SUS pela modalidade fundo a fundo. Também foram identificados indícios de que pode haver fatores políticos influenciando o recebimento de recursos do SUS.
Critérios de classificação para ocupação informal: Consequências para a caracterização do setor informal e para a análise de bem-estar no Brasil
Authors: Corseuil Carlos Henrique , Reis Mauricio Cortez , Brito Alessandra Scalioni
Published: July 2015

Resumo O objetivo deste texto é identificar a sensibilidade da caracterização do trabalhador informal a distintos critérios de classificação entre formal e informal, e mostrar como a relação entre informalidade e medidas de bem-estar dos trabalhadores varia de acordo com o critério de classificação adotado. Como contribuições à literatura, tem-se a análise desagregada para os grupos de empregados e empresários e o uso de um critério recém-disponibilizado para classificar os empresários em formais ou informais, baseado na informação sobre a inclusão no Cadastro Nacional de Pessoa Jurídica (CNPJ). De forma geral, tanto a caracterização do setor informal como a relação entre informalidade e bem-estar são muito parecidas em dois dos três critérios usados; estes são: i) o critério via contribuição à previdência; e ii) o critério baseado no CNPJ para empresários e na carteira de trabalho para empregados.
Fibre-reinforced concrete beam assemblages subject to column loss
Authors: Valipour Hamid , Vessali Nima , Foster Stephen
Published: July 2015

Application of steel-fibre-reinforced concrete (SFRC) to partially replace conventional steel reinforcement, particularly the stirrups in beams, has found increasing use in practice. However, the collapse response of SFRC beams (with no stirrups) subject to column loss scenario has not been investigated. Accordingly, four 2/5th scale beam sub-assemblages with SFRC and no stirrups are constructed and tested under a column loss scenario and the potential for steel fibres to replace the stirrups is investigated. The experimental results show that the use of structural steel fibres as a replacement for stirrups has a minor influence on the membrane behaviour of beams as well as the robustness of SFRC frames subjected to column loss. In addition, detailed finite-element models of the assemblages are developed and validated against the experimental data and the validated models are used to investigate the influence of steel bar ductility on the ability of beams to develop tensile membrane action. It is concluded that the minimum ductility requirements adopted by the Australian standard for normal ductility reinforcing bars (minimum uniform elongation of 0·05) is not sufficient to allow full development of catenary action in reinforced concrete/SFRC beams.
ESTUDO NUMÉRICO DE FUNDAÇÕES SUPERFICIAIS SOBRE SISTEMA DE DUPLA CAMADA
Authors: Faro Vítor Pereira , Consoli Nilo Cesar
Published: July 2015

Foi estudado, através do Método dos Elementos Finitos, o comportamento de fundações superficiais assentes em sistemas de dupla camada, sendo a superior artificialmente cimentada, com uma largura igual a três vezes o diâmetro da fundação. Sendo H a espessura de solo cimentado e D o diâmetro da fundação, foram feitas diversas simulações para as várias relações H/D (desde zero até 4,0). Depois de confirmada a influência da relação H/D na resposta carga x recalque de fundações superficiais, foi feita uma análise paramétrica após a qual é proposta uma nova metodologia de dimensionamento de fundações superficiais assentes em sistema de dupla camada, sendo a superior cimentada. Finalmente, a capacidade de suporte de fundações superficiais assentes em camadas cimentadas foram simuladas com sucesso através da nova metodologia apresentada. Para a prática da engenharia o método proposto, através de curvas carga-recalque, fornece boas previsões para a obtenção da capacidade de suporte de fundações superficiais.

O principal objetivo do presente trabalho foi avaliar, experimentalmente e analiticamente, a capacidade de carga, por nível, de dois diferentes tipos de “prateleiras miscelâneas”. Esta avaliação consistiu na realização de ensaios mecânicos, isto é, testes experimentais de carregamento dos níveis das prateleiras e modelamento através de elementos finitos das mesmas. Os resultados mostraram que os testes experimentais estão de acordo com o modelo analítico quanto aos pontos de maiores tensões e rupturas.

Published: July 2015

Este trabalho apresenta o estudo de um solo residual de gnaisse da cidade de Porto Alegre, no que tange a compressão. Este solo residual apresenta marcado bandamento gnáissico herdado da rocha mãe, que lhe confere uma forte anisotropia textural. Foram executados ensaios de compressão isotrópica e confinada em amostras reconstituídas e ensaios de compressão confinada com amostras indeformadas com diferentes ângulos entre o bandamento gnáissico e a direção de aplicação da tensão principal maior (ângulo d). A interpretação dos resultados foi realizada a luz da Teoria do Estado Crítico. Verificou-se a determinação de uma linha de compressão normal (NCL) para as amostras reconstituídas, tanto em compressão isotrópica como em compressão confinada, entretanto as amostras indeformadas apresentaram retas paralelas no plano n:logs’v dependentes do valor de d (para os níveis de tensão estudados).
GERAÇÃO DE RESÍDUOS NO PROCESSAMENTO DE ÁGATAS
Authors: Almeida Silva Rodrigo De , Schneider Ivo André H.
Published: July 2015

O Brasil é um dos o principais produtores de gemas de cor, e o Rio Grande do Sul o estado com maior produção de ágatas ametistas e citrinos. Este setor é preponderante na economia das regiões do Alto Uruguai e Planalto Médio, mas apresenta dificuldades tecnológicas, onde destacam-se o grande volume de gemas exportadas em estado bruto com baixo valor agregado e equipamentos com baixa eficiência. Um outro problema detectado é o grande volume de resíduos gerados sem tratamento e destinação adequada. O objetivo do presente trabalho é realizar um diagnóstico do beneficiamento das gemas, identificar os tipos  de resíduos gerados e a importância da aplicação da gestão ambiental para este setor industrial. Pode-se concluir que, de forma geral, o setor apresenta um descaso com o meio ambiente onde poucas empresas tratam seus resíduos ainda com a visão de “fim de tubo”.
ANÁLISE TÉRMICA E ENERGÉTICA DA APLICAÇÃO DE ISOLANTE TÉRMICO EM FACHADAS E COBERTURA DE UM EDIFÍCIO COMERCIAL
Authors: Melo Ana Paula , Matos Barcelos Michele , Folle Daiane
Published: July 2015

Este estudo apresenta os resultados das simulações realizadas no programa EnergyPlus do comportamento térmico e energético de um edifício comercial. Com base nesta edificação foram analisadas diferentes alternativas de percentual de abertura nas fachadas, densidade de cargas internas, fator solar e condições de isolamento térmico das paredes e coberturas para a cidade de São Paulo. Através das simulações concluiu-se que a isolação de paredes e cobertura reduz o consumo de energia elétrica de grande parte dos casos simulados para a tipologia analisada, principalmente para os casos com baixa densidade de carga interna, sendo a redução na capacidade instalada em sistema de condicionamento de ar mais significativa.

Trayectorias sociales improbables: adolescentes chilenos de estratos bajos competentes en lectura
Authors: Ortiz Iván
Published: July 2015

Se ha vuelto de sentido común constatar que los logros en el aprendizaje de los estudiantes de origen social popular resultan inferiores en comparación con sus pares más privilegiados, como lo señalan las teorías de la reproducción social. Este artículo, por el contrario, fija la mirada en los casos que escapan a esta tendencia, es decir, en los estudiantes de estrato social bajo que obtienen buenos resultados académicos. Mediante análisis de regresión logística se averiguó qué tipo de factores individuales, de las escuelas y de los padres, se asocian con los estudiantes chilenos de nivel socioeconómico bajo que obtuvieron buenos resultados en la prueba de competencia lectora del estudio PISA 2009. Las variables de los estudiantes resultaron tener más fuerza predictiva que las de las escuelas y que las de los padres. Se discuten estos resultados. AbstractIt is generally believed that students from low-income families are less successful at school, as indicated by theories of social reproduction. This article focuses on Chilean students that, in spite of their social background, have performed well in the Programme for International Student Assessment (PISA) 2009. Using logistic regression analysis we identify factors associated with academic achievement in reading. Results show that student variables have a greater explanatory value than family and school variables.
Calificando al Presidente y percibiendo el aumento del crimen en México
Authors: Gómez Vilchis Ricardo R.
Published: July 2015

¿Qué tan importante es la percepción del aumento del crimen cuando el ciudadano califica al Presidente? Este artículo expone a México como un estudio de caso para examinar esta relación. La investigación emplea 11 encuestas nacionales de 1994 a 2006. El estudio analiza los efectos de la percepción del crimen en la calificación que los mexicanos otorgan al Ejecutivo antes y después de la elección del año 2000. La proposición principal es que después de la transición de 2000, la percepción del crimen, junto con la de otras variables económicas, se vuelve más relevante y tiene efectos más fuertes cuando la gente evalúa al Presidente, debido a un incremento de las expectativas de la ciudadanía en torno a la competencia del Ejecutivo.AbstractHow important are citizen perceptions of an increase in crime rate when they evaluate the President? This article uses Mexico as a case study to examine the relationship between perception of crime and citizen grading of the President. The research uses 11 national surveys from 1994 to 2006 to analyze the effects of perception of crime on citizen grading of the President before and after the 2000 presidential election. The main proposition is that, after the 2000 political transition, perception of crime, together with other economic variables, becomes more relevant and has stronger effects when citizens evaluate the President due to an increase of their expectations of the Executive's competence.
La construcción discursiva de la prevención del delito en México 2006-2009
Authors: Quintana Navarrete Miguel
Published: July 2015

Este estudio analiza la construcción discursiva de la prevención del delito en México durante la primera mitad de la presidencia de Felipe Calderón. Se distinguen las características de diversos sujetos y objetos — así como de las relaciones entre ellos— creados y representados en el discurso oficial preventivo. El análisis revela el sustento axiológico neoconservador de la prevención y el modo en que sus principios son "operacionalizados" con el fin de articularlos a la experiencia cotidiana. Los hallazgos dan sustento empírico a teorías y conceptos criminológicos contemporáneos, principalmente los de "criminologías de uno mismo" y "criminologías del otro", muestran la construcción discursiva de una prevención familiar del delito como un tipo específico de prevención.AbstractThis study analyzes the discursive construction of crime prevention in Mexico during the first half of Felipe Calderón's presidency. The characteristics of different subjects and objects — as well as the relations between them— created and represented in the official discourse are distinguished. The analysis reveals the neo-conservative axiological basis of crime prevention, and the way its tenets are "operationalized" in order to articulate them to everyday experience. The findings provide empirical support to contemporary criminological theories and concepts, mainly the notions of "criminologies of the self" and "criminologies of the other", and reveal the discursive construction of a distinct type of crime prevention based on the family.
Use of a Double‐Layer Technique With an Acellular Dermal Matrix to Treat Miller Class I and II Gingival Recession Defects: 4‐ to 5‐Year Results
Authors: Mahn Douglas H.
Published: July 2015

Introduction: The purpose of this retrospective record review is to evaluate the long‐term performance of a double‐layer technique using an acellular dermal matrix (ADM) in conjunction with a coronally advanced flap (CAF) in treating Miller Class I and II gingival recession defects (GRDs).

Case Series: A total of 26 patients with isolated Class I and II GRDs were treated. These patients were treated as part of routine clinical practice based on the individual needs of the patient. After 4 to 5 years (48 to 66 months), the mean GRD decreased from 4.0 ± 1.0 to 0.3 ± 0.6 mm. This represents 92.5% root coverage. Complete root coverage was achieved in 69.2% of the cases. Improvements were also found for probing depths and clinical attachment levels at 4 to 5 years.

Conclusion: These results support the use of a double‐layer technique using an ADM in conjunction with a CAF in treating Class I and II GRDs.
On a property of moduli of smoothness and K-functionals
Authors: Agratini Octavian
Published: July 2015

A new property of moduli of smoothness associated to functions belonging to
some certain spaces is revealed. In terms of statistical convergence, we
determine the behavior of these special functions at the point ? = 0. In this
respect, Peetre?s K-functional is also investigated.
Anti-invariant Riemannian submersions from cosymplectic manifolds onto Riemannian manifolds
Authors: Murathan Cengizhan , Küpeli Erken
Published: July 2015

We introduce anti-invariant Riemannian submersions from cosymplectic
manifolds onto Riemannian manifolds. We survey main results of anti-invariant
Riemannian submersions defined on cosymplectic manifolds. We investigate
necessary and sufficient condition for an anti-invariant Riemannian
submersion to be totally geodesic and harmonic. We give examples of
anti-invariant submersions such that characteristic vector field ? is
vertical or horizontal. Moreover we give decomposition theorems by using the
existence of anti-invariant Riemannian submersions.

A fixed point theorem for a generalized weak contractive map in a metric
space is proven by generalizing some recent results of Djoric [4, Theorem
2.2], Zhang and Song [30, Corollary 2.2] and others. The result is
illustrated by examples.
