Characterization of a hybrid polyacrylamide and its flocculation properties in cyanide tailing suspensions
Authors: Liu Ya , Lv Cuicui , Ding Jian , Qian Peng , Yu Yang , Ye Shufeng , Chen Yunfa
Published: July 2017

An inorganic-organic hybrid flocculant Al(OH)3-polyacrylamide (Al-PAM) with narrow molecular weight distribution was synthesized using inverse microemulsion polymerization. The hybrid polymer Al-PAM was characterized by Infrared spectroscopy, thermogravimetric analysis, transmission electron microscopy and scanning electron microscopy, and it was found that it had a ‘star-like’ structure in which Al(OH)3 colloidal particles acted as cores linking PAM chains. The properties of Al-PAM were investigated in flocculating 10 wt% cyanide tailing suspensions. It was found that as the amount of Al-PAMM1 with high molecular weight and aluminum content increased, the initial settling rate of particles accelerated, achieving the maximum 6.6 m/h, 17.3 times the rate of the control without flocculants. The turbidity of the supernatant decreased to 35 ± 2 NTU accordingly, compared to 353 ± 2 NTU of that in the control, which meant that 90.0% of turbidity was removed from the cyanide tailing suspensions. The flocculation mechanism was further explored by floccule size and ζ potential measurements. The superior performance of cationic Al-PAM in flocculating negatively charged particles compared to commercial non-ionic GG indicated that electrostatic repulsion between tailing particles was a crucial factor in deciding the flocculation performance of the polymer. The study demonstrated that both charge neutralization and bridge adsorption were conductive to the particle flocculation.
Cost minimization in a full-scale conventional wastewater treatment plant: associated costs of biological energy consumption versus sludge production
Authors: Sid S. , Volant A. , Lesage G. , Heran M.
Published: July 2017

Energy consumption and sludge production minimization represent rising challenges for wastewater treatment plants (WWTPs). The goal of this study is to investigate how energy is consumed throughout the whole plant and how operating conditions affect this energy demand. A WWTP based on the activated sludge process was selected as a case study. Simulations were performed using a pre-compiled model implemented in GPS-X simulation software. Model validation was carried out by comparing experimental and modeling data of the dynamic behavior of the mixed liquor suspended solids (MLSS) concentration and nitrogen compounds concentration, energy consumption for aeration, mixing and sludge treatment and annual sludge production over a three year exercise. In this plant, the energy required for bioreactor aeration was calculated at approximately 44% of the total energy demand. A cost optimization strategy was applied by varying the MLSS concentrations (from 1 to 8 gTSS/L) while recording energy consumption, sludge production and effluent quality. An increase of MLSS led to an increase of the oxygen requirement for biomass aeration, but it also reduced total sludge production. Results permit identification of a key MLSS concentration allowing identification of the best compromise between levels of treatment required, biological energy demand and sludge production while minimizing the overall costs.

Published: July 2017

The capacity of Cladosporium cladosporioides biomass for removal of Cr(VI) in aqueous solutions was evaluated. A 2 × 2 factorial experiment design was used to study the effects of pH and biomass doses. Lower pH values and larger biomass doses increased the capacity of C. cladosporioides biomass for removal of Cr(VI), reaching a reduction capacity of 492.85 mg g−1, a significantly higher value compared to other biomass reported. Cr(VI) removal kinetic rates followed a pseudo-second order model, like other fungal biomass reported previously. The apparent adsorption process was described well by the Freundlich isothermal model. However, determination of total chromium indicated that adsorption of Cr(VI) was followed by a redox reaction that released proportional quantities of Cr(III) into the experimental supernatant, suggesting a parallel adsorption-reduction process. Comparison of Fourier transform infrared spectroscopy spectra of C. cladosporioides biomass before and after the reduction process demonstrated the involvement of positively charged amino groups in the Cr(VI) adsorption-reduction process.
Cold Rolling Effects on Material Properties in Pallet Rack Uprights
Authors: Crisan Andrei , Dogariu Adrian Ioan
Published: July 2017

Pallet rack structures are usually made up of thin walled cold formed steel sections. The cold rolling process changes the material properties, increasing the yield strength and tensile strength across the section. According to EN1993-1-3, an equivalent yielding strength is allowed to be considered in design to account for the changes in material properties. It has to be mentioned that this approach does not take into account the residual stresses that arise following the forming process. The current paper presents the experimental evidence of residual stresses as result cold rolling process for two pallet rack upright sections. Based on experimental findings, a series of numerical models were created in order investigate the influence of residual stresses onto the load bearing capacity of pallet rack uprights. The experimental program was developed within the CEMSIG Research Centre (http://cemsig.ct.upt.ro) of “Politehnica” University of Timisoara. The increase of yield strength and tensile strength across the cross-section was also experimentally determined.
Concentrically Braced Frames: European vs. North American Seismic Design Provisions
Authors: Costanzo Silvia , Raffaele Landolfo
Published: July 2017

A critical review of seismic design provisions for concentrically braced frames (CBFs) in both European and North American (i.e. US and Canadian) codes is presented in this paper. Indeed, even though those codes are based on capacity design philosophy, different requirements and different approaches are used to guarantee the hierarchy of resistances between dissipative and non-dissipative elements, thus leading different overall seismic performance. In detail, the main issues critically discussed are (i) the ductility classes and the correlated force-reduction factors; (ii) the structural analysis methods permitted by different codes; (iii) the modelling aspects of braces; (iv) the detailing rules for both dissipative (bracing members) and non-dissipative elements. Synoptic tables summarizing the corresponding assumptions and requirements in different codes are provided.

Acerca de cómo los aymara aprendieron el castellano (terminando por olvidar el aymara)
Authors: Gundermann Kröll Hans Herbert
Published: July 2017

¿Cómo es que entre la población indígena de Arica y Tarapacá durante el poco más de un siglo y medio de vida republicana, el aymara ha transitado desde el estatus de lengua dominante a la de lengua subordinada en rápido retroceso ante el castellano? Se diagnostica la situación actual de esta lengua y se desarrolla una explicación histórica de los principales cambios. Una y otra se apoyan en una encuesta sociolingüística y en información etnográfica e histórica.Los resultados emergentes de tales fuentes son coherentes entre sí y apuntan en la misma dirección. Para elaborar una explicación se acude a la identificación de factores de estructuración del campo de fuerzas intervinientes en las transformaciones lingüísticas y se postulan procesos a través de los cuales esas fuerzas van dirigiendo el cambio en el sentido indicado. ABSTRACTHow has the Aymara language changed among the indigenous people in Arica and Tarapaca for nearly a century and a half of republican life from its dominant language status to a subordinate condition in fast retreat before the Spanish language? In this article, the current status of this language is diagnosed and a historical explanation about the principal changes is developed. Diagnose and explanation are based on a socio-linguistic survey and on historical and ethnographic information. Results coming from such sources are coherent each other and both aim at the same direction. The explanation is developed by means of structuration factors of participating forces in the linguistic changes; besides, processes governing changes are postulated.
Una crítica a los paradigmas modernizantes y reproductivista en la investigación educativa de los aymaras de Tarapacá
Authors: González Miranda Sergio Alberto
Published: July 2017

Este artículo analiza críticamente a las teorías modernizantes y reproductivistas en la investigación en educación, especialmente el dualismo que ambas proponen para entender la realidad. Por lo tanto, se discute la eficacia explicativa de estas teorías en realidades como la de los pueblos indígenas latinoamericanos. De tal modo se cuestiona la pretendida universalidad de dichas teorías. Se toman ejemplos de estudios sobre los aymaras de Tarapacá, Chile, realizados por investigadores que se orientaron por las teorías modernizantes y reproductivistas, para demostrar principalmente las dificultades teórico-metodológicas que significa la realidad indígena para una teoría occidental con pretensión universal. En definitiva, este artículo pretende ser un aporte a la investigación educativa en pueblos indígenas latinoamericanos, tomando como ejemplo a los aymaras de Tarapacá, Chile, por medio de una discusión teórico-metodológica.ABSTRACTThis article critically analyzes the modernishing and reproductivist theories in education research, specially the dualism that both of them propose in order to understand reality. Therefore, their explanatory effectiveness concerning the realities of Latin American native groups is discussed. Examples are taken from studies of the Aymaras from Tarapacá, Chile, carried out by researchers oriented towards the modernishing and or reproductivist theories, mainly to point out the methodological and theoretical difficulties confronted by Western theories with universal pretentions when dealing with the indigenous reality. Succinctly, by means of a theoretical and methodological discussion, this article intends to be a contribution to the educational research of Latin American native populations with the example of the Aymaras of Tarapacá, Chile.

Este estudio analiza las características que adquirió el control político de las comunidades atacameñas por parte del corregidor de indios, el que, sumido en la ideología demonológica de la época, en su expresión popular, cree descubrir prácticas de brujería que adquieren un carácter subversivo al afectarlo personalmente. Por intermedio de este proceso judicial conocemos de las prácticas de un significativo número de curanderos y de los conflictos que existían entre aquellos curanderos más prestigiosos y las autoridades étnicas de Atacama. ABSTRACTThis paper analyzes the characteristics of political control over Atacaman communities that was exercised by the corregidor of Indians. This official, steeped in the popular demonological ideology of his time, believed that he had discovered manifestations of witchcraft. Because they affected him personally, he found them to be subversive. Through the study of this judicial process, welearn about the practices of a significant number of native healers and the conflicts that existed between the most prestigious of these curanderos and the Atacaman ethnic authorities.
An Analysis of How the Gender and Race of School Principals Influence Their Perception of Multicultural Education
Authors: McCray Carlos R. , Beachum Floyd D.
Published: July 2017

The purpose of this study was to investigate secondary school principals’ perceptions of multicultural education in a rural southeastern state. The researchers wanted to ascertain whether or not the race or gender of school principals have a role in how those principals view multicultural education in theory (its theoretical value). For the purpose of this study, multicultural education in theory was defined as the belief that multicultural education is for all students, elevates students’ self-esteem, is embedded in cultural pluralism, and recognizes the social, political, and economic community and societal constructs on students of color (Fernandez, 1996). Three hundred and two secondary school principals were surveyed in a designated southeastern state. A significant difference was discovered with regard to the gender of the school principals and their perceptions of the theoretical value of multicultural education.
A Study of School Size among Alabama’s Public High Schools
Authors: Lindahl Ronald A. , Cain, Sr. Patrick M.
Published: July 2017

The purpose of this study was to examine the relationship between the size of Alabama’s public high schools, selected school quality and financial indicators, and their students’ performance on standardized exams. When the socioeconomic level of the student bodies is held constant, the size of high schools in Alabama has relatively little relationship with 11th grade student (both regular and special education) performance on the reading and math portions of the AHSGE. High schools’ average daily attendance rates and pupil-to-computer (and computer with Internet connections) ratios do not vary in accordance with school size. Higher percentages of highly qualified teachers are found in Alabama’s largest high schools. There was very little difference in the percentage of teachers with a master’s degree or above across school size categories. Very little difference exists across size categories in regard to mean expenditures per pupil (range = $7,322 to $7,829). However, districts of the large high schools exert over twice the effort of those with small high schools (3.2 mills to 1.5 mills) and approximately 50 percent greater local effort than the districts of the medium-size high schools.
Juggling Educational Ends: Non-Indigenous Yukon Principals and the Policy Challenges That They Face
Authors: Blakesley Simon
Published: July 2017

This article reports on a 2008 study of non-indigenous principals working in Indigenous Yukon contexts. It examines the policy contexts in which Yukon principals are embedded, giving specific attention to how they address the tensions that exist as a result of operating at the intersections of micro, meso, and macro policy levels. The application of critical ethnography generates the opportunity to reveal and examine the tensions, distinctions, and contradictions underpinning their praxis, exposing the multifaceted and conflictual power structures in which they are embedded. The principals identify fragmented curricular policy; the competition between instructional time, mandated external curricula, and locally developed curricula; and field trip and hiring policies as being problematic. The principals also describe how they cope with the challenges and tensions that arise as a result of being responsible and accountable to balance competing educational ends to the satisfaction of multiple external levels of control.
Stakeholder Perceptions of Barriers and Solutions to Significant Post-Secondary Enrollment Option Expansion for High School Students
Authors: Wozniak Carl , Bierlein Palmer Louann
Published: July 2017

Post-secondary experiences for students still in high school have been promoted as a means to increase academic rigor and create a better-trained workforce. Yet little is known regarding supports needed to significantly increase such options. This study obtained input from 411 stakeholders in one Midwestern state, including 201 district superintendents, 181 high school principals, and 23 college dual enrollment officers regarding their use of these options, their perceptions of barriers to program expansion, and their ranking of possible solutions to overcome the barriers. Findings demonstrate that all parties find postsecondary options of value, with traditional dual enrollment the most used option. Although all groups identified funding as a primary barrier, other systemic barriers were of great concern. Participants suggest that expansion of Advanced Placement and early and middle college programs, financial assistance for dually enrolled students, and increased program availability for career and technical options would be beneficial.
Education for a New Era: Stakeholders’ Perception of Qatari Education Reform
Authors: Ellili-Cherif Maha , Romanowski Michael Henry
Published: July 2017

The paper reports the results of a qualitative research study that explores principal, teacher, and parent perceptions with regard to Qatar’s education reform, Education for a New Era (EFNE) launched in 2004. The study focuses on the effects of the reform on each group, their perceived advantages and disadvantages of the reform, and the challenges they face in the implementation of EFNE. Data for this study was collected through an open-ended questionnaire. The results point to the positive effects of EFNE on improving instruction, principals' leadership style, and learner attitude to education. These stakeholders believe that the reform is too ambitious and sometimes unrealistic. The three groups also report challenges that revolve around the amount of extra effort and work it requires from them, the continuous reform changes, and the threats to the local culture and language. Discussion and conclusions are provided regarding EFNE.
Democratic Dialogue as a Process to Inform Public Policy
Authors: Smith Deirdre M. , Qua-Hiansen Jessica
Published: July 2017

An exploration of the collaborative reconceptualization of a provincial Supervisory Officer’s Qualification Program (SOQP) through the use of dialogic approaches is the focus of this inquiry. The stories, perspectives, and lived experiences of supervisory officers, principals, teachers, parents, students, and members of the public in Ontario were included as essential voices and information sources within policy development conversations. These narratives of experience revealed the forms of knowledge, skills, dispositions, and ethical commitments necessary for effective supervisory officers today and in the future. They also illustrated the transformative nature of narrative dialogue to enlighten, deepen understanding, and alter perspectives. The policy development processes used in this publicly shared educational initiative

serve as a model of democratic dialogue. The inclusive and dialogic methods

employed to collectively reconceptualize a supervisory officer formation program illustrate

an innovative framework for developing policies governing the public good.

Suggestions for research to extend the field are provided.
What They Think About How They Are Evaluated: Perspectives of New York State Physical Educators on Teacher Evaluation Policy
Authors: Seymour Clancy M , Garrison Mark J
Published: July 2017

While research on high stakes testing continues to expand, little is known regarding how the use of student test scores to evaluate teachers is affecting physical education (PE).Â  A proportionate, stratified random sample of physical educators in New York State was drawn (n=489) to survey them about their district’s practices and their attitudes about the state’s new teacher evaluation policy. Results indicated that 38% of respondents were evaluated in part on the basis of results from written tests of students, while 27% indicated their district used student fitness tests for this purpose. Â Eighteen percent of respondents reported their district used state mandated English Language Arts (ELA) and mathematics test scores in calculating physical educator performance ranks. While few reported using performance-based measures, 94% of respondents indicated these as the preferred means of assessment in PE. Eighty-three percent of respondents predicted that the new teacher evaluation system would not improve PE.

O objetivo deste artigo é traçar perfil da vitimização sexual de crianças e adolescentes, segundo descrição de casos por alunos e professores de escolas públicas. Trata-se de estudo transversal, envolvendo alunos (14 a 19 anos), ambos os sexos e professores da Rede/Feira de Santana, 2006. A amostragem foi por conglomerado (estágios múltiplos), selecionando-se aleatoriamente escolas de diferentes portes (10), alunos (732) e professores (88), respeitando proporcionalidade e representatividade (42 escolas); utilizou-se instrumento autoaplicável e sigiloso. Os resultados mostraram que alunos de ambos os sexos e faixas etárias citaram maiores proporções de estupro; identificaram-se casos ocorridos no domicílio ou comunidade, divulgados e denunciados pela mãe; perpetrado pelo pai e a maioria das vítimas estava na faixa de 12 a 16 anos; a proporção de vitimização também na infância (acima de 30%) foi alta; alunos mais jovens descreveram maiores proporções de agressores desconhecidos e ocorrências na comunidade; a pedofilia foi citada por mais de 20% do sexo masculino e da faixa de 17 a 19 anos. Professores descreveram estupros ocorridos no domicílio, denunciados pelas mães, perpetrados pelos pais, usando intimidação verbal e outras. Concluiu-se que a proximidade da escola com a violência infanto-juvenil fazendo parte do cotidiano das famílias e grupos aponta necessidade de práticas, destacando sensibilização para a identificação e notificação de casos.

Este estudo analisou fatores associados à realização de consulta médica pelos adultos, por meio de estudo transversal com 1.059 pessoas na faixa etária de 20 a 59 anos. Utilizou dados amostrais de inquérito populacional realizado em outubro/2006 a fevereiro/2007, nos municípios de São Luís, Imperatriz, São José de Ribamar, Timon, Codó, Caxias do estado do Maranhão. Foram calculadas razões ajustadas de prevalência e intervalos de confiança de 95%, utilizando-se regressão de Poisson. Consulta médica nos últimos 15 dias foi a variável dependente e fatores socioeconômicos (renda familiar mensal, escolaridade, beneficiário de plano de saúde), demográficos (sexo, idade e cor da pele), uso de medicamentos, automedicação, cobertura pelo Programa de Saúde da Família (PSF) e autoavaliação do estado de saúde, as independentes. As razões de prevalência mostraram que referir morbidade e possuir plano de saúde aumentaram a probabilidade de consulta. A automedicação apresentou alta prevalência e associou-se negativamente ao desfecho. Entretanto, dos que referiram morbidade, 78,3% não consultaram, sugerindo barreiras de acesso. Não houve associação com as variáveis idade, sexo, cor da pele, uso de medicamento, escolaridade e renda familiar, assim como cobertura pelo PSF, o que sugere dificuldade de acesso até na atenção básica. A autoavaliação do estado de saúde não mostrou associação.

Published: July 2017

O objetivo do estudo foi avaliar as pressões respiratórias máximas e a autonomia funcional de idosos em instituições de longa permanência. A amostra foi dividida por gênero: mulheres (n=11, idade=75,45±12,04 anos) e homens (n=13, idade=69,08±8,76 anos). As pressões respiratórias máximas (Pimáx e Pemáx) foram aferidas pelo Manovacuômetro (Analógico com intervalo operacional de -150 a +150 cmH2O; Critical Med/USA-2002) e comparadas com valores para normalidade. Para avaliação da Autonomia Funcional, utilizou-se o protocolo do Grupo de Desenvolvimento Latino Americano para a Maturidade (GDLAM). A análise estatística foi descritiva e inferencial de Shapiro-Wilk (normalidade). Nos resultados, observou-se diminuição das pressões respiratórias máximas (Pimáx e Pemáx, respectivamente) para ambos os gêneros: mulheres (-42,18±27,06 cmH2O e 38,73±9,73 cmH2O) e homens (62,00±28,39 cmH2O e 69,08±28,93 cmH2O). De modo semelhante, a avaliação da autonomia funcional foi considerada fraca. Pôde-se concluir que, a despeito de estarem assintomáticos, os idosos possuem diminuições significativas das pressões respiratórias máximas e da autonomia funcional que podem repercutir em complicações pulmonares importantes frente às alterações inerentes à senescência.

Published: July 2017

A pesquisa refere-se às possibilidades de apoio comunitário às famílias para que adolescentes moradores da Comunidade do Bom Jardim, Fortaleza, Ceará, possam abandonar o uso de drogas ilícitas. A família do usuário de drogas ilícitas apresenta, com muita frequência, além de história de múltiplas vulnerabilidades socioeconômico-culturais, grandes dificuldades em propiciar aos filhos o estímulo necessário à conquista da independência e da autonomia. O método utilizado é qualitativo, descritivo, exploratório, numa perspectiva analítico crítica. Com base em estudo anterior realizado com os adolescentes acompanhados na Comunidade, por meio de técnica de observação direta e grupo focal, dez mães foram abordadas por meio de entrevistas estruturadas. O procedimento foi acompanhado do registro de impressões, por parte do pesquisador, em diário de campo. A análise dos resultados seguiu os procedimentos de Análise de Discurso. Os resultados encontrados indicam que as famílias representadas pelas mães incluídas na pesquisa pertencem a um contexto amplo, gerador de influências complexas, e podem sair da condição de responsáveis pelo abuso, para uma atitude claramente positiva, quando compreendem a dependência química como doença e apoiam de modo firme o processo de cuidado desenvolvido por uma equipe terapêutica motivada por uma perspectiva psicossocial ativa.

A prevalência de hipertensão arterial entre os idosos é alta e o uso correto dos medicamentos anti-hipertensivos pode proporcionar grandes benefícios para essas pessoas. O presente estudo tem como objetivo caracterizar as classes mais prescritas aos idosos que utilizam os serviços de diferentes Unidades de Saúde da Família (USF) do município de Marília (SP). O estudo é descritivo e retrospectivo, e os dados foram coletados dos prontuários de 382 idosos pertencentes a quatro USF. Constatou-se que a classe dos tiazídicos foi a mais prescrita nas quatro unidades, tanto como monoterapia quanto em associação com outras classes. Os inibidores da enzima conversora de angiotensina compõem a segunda classe de anti-hipertensivos mais utilizada nas quatro unidades estudadas, tanto de forma isolada como em associações. Os betabloqueadores, os bloqueadores dos canais de cálcio e os diuréticos de alça foram menos utilizados. Praticamente não houve diferenças estatisticamente significativas na prescrição das classes medicamentosas entre as unidades. Tais constatações evidenciam que as prescrições de anti-hipertensivos para os idosos, nas unidades analisadas, estão em conformidade com as evidências da literatura geriátrica e gerontológica.

Here, economic losses caused by cattle parasites in Mexico were estimated on an annual basis. The main factors taken into consideration for this assessment included the total number of animals at risk, potential detrimental effects of parasitism on milk production or weight gain, and records of condemnation on livestock byproducts. Estimates in US dollars (US$) were based on reported yield losses in untreated animals. These estimates reflect the major effects on cattle productivity of six parasites, or parasite group. The potential economic impact (US$ millions) was: gastrointestinal nematodes US$ 445.10; coccidia (Eimeria spp.) US$ 23.78; liver fluke (Fasciola hepatica) US$ 130.91; cattle tick (Rhipicephalus microplus) US$ 573.61; horn fly (Haematobia irritans) US$ 231.67; and stable fly (Stomoxys calcitrans) US$ 6.79. Overall, the yearly economic loss due to the six major parasites of cattle in Mexico was estimated to be US$ 1.41 billion. Considering that the national cattle herd registered in 2013 included 32.40 million head, the estimated yearly loss per head was US$ 43.57. The limitations of some of the baseline studies used to develop these estimates, particularly when extrapolated from local situations to a national scale, are acknowledged. However, the general picture obtained from the present effort demonstrates the magnitude and importance of cattle parasitism in Mexico and the challenges to maximize profitability by the livestock industry without adapting sustainable and integrated parasite control strategies.

El queso botanero que se produce en el noreste del Estado de México, se caracteriza porque se elabora con leche cruda, lo que representa un riesgo en cuanto a su calidad higiénico-sanitaria. Se presenta solo o se le adiciona chile cuaresmeño fresco y epazote o chile chipotle. A estos condimentos se les han asociado propiedades bactericidas y bacteriostáticas. El objetivo de este trabajo fue determinar si los condimentos adicionados al queso botanero, influyen en los conteos de unidades formadoras de colonia (UFC) de lactobacillus, coliformes totales (COL), Staphylococcus aureus (S. aureus) y levaduras (LEV), y el pH (características fisicoquímicas) de las variedades de queso botanero analizadas. El estudio se realizó en una quesería de tipo familiar del noreste del Estado de México (método de invitación). Se realizó el conteo de Lactobacillus, COL, S. aureus y LEV, los recuentos fueron superiores a los permitidos para COL (100 UFC/g y 10,000 UFC/g), S. aureus (1,000 UFC/g y 100 UFC/g) y LEV (500 UFC/g). Los condimentos adicionados al queso artesanal modifican los conteos de UFC/g, pero no los disminuyen a valores permitidos por la normatividad
The solid angle subtended by a collimated detector and a nuclear fuel assembly
Authors: Nicolaou Georgios
Published: July 2017

A Monte Carlo procedure is presented to calculate the solid angle subtended
between a HPGe collimated detector and a PWR 17 x 17 fuel assembly.
Self-shielding within the assembly is assessed in the case of gamma rays
encountered in gamma spectroscopy of spent nuclear fuel. Self-shielding
renders a non-uniform 3-D distribution of the radioactivity within the
assembly whose extend depends on gamma ray energies of interest. Hence, the
solid angle is reduced to an effective one for each of the different energies
of interest.

Introduction/Objective. Class II malocclusions are sagittal malocclusions
characterized by a distal relationship of posterior teeth. Depending on the
underlying problem, class II can be skeletal or dentoalveolar. Class II
treatment modality will depend on the cause, severity and age. Growth
modification is the best treatment option in skeletal Class II growing
patients. The aim of this study was to establish and compare sagittal and
vertical skeletal and dental changes in patients treated with the ?M block?
appliance, the Fr?nkel functional regulator and the Balters? Bionator.
Methods. The sample consisted of 70 patients diagnosed with skeletal class II
(ANB > 4?) and mandibular retrognathism (SNB < 80?). Patients were divided
into 3 groups according to the type of appliance. All patients went through
the standard diagnostic procedure (anamnesis, clinical and functional
analysis, study model, panoramic radiograph and cephalometric analysis) and
dental and skeletal age was determined. Treatment effects were analyzed on
study models and cephalograms at the end of treatment. Results. All
appliances led to significant mandibular anterior movement and sagittal
growth, which reduced ANB values. All three groups of patients presented with
neutral growth pattern, upper incisor retrusion and lower incisor protrusion
at the end of treatment. Conclusion. Results of this study indicate efficacy
of all three appliances in skeletal class II treatment.
On the application of Gaston Bachelard’s philosophy of science and epistemology to the problem of understanding in history of sociology
Authors: Petrovic Dejan
Published: July 2017

Sketch of the methodological approach, alternative to presentism and
historicism, based on the Gaston Bachelard?s philosophy of science and
epistemology and its key concepts like epistemological break, epistemological
obstacle and error, will be showed in this text. These two dominant
methodological approaches in history of sociology and its similar disciplines
try, each in its own way, to provide solution to fundamental problem of the
said disciplines, thus the problem of understanding. In other words, how to
come to the proper interpretation of specific author?s thought through the
analysis of texts left behind him? As it will be presented below, the basic
characteristics of presentism and historicism, and therefore their
shortcomings, arise from the specific model of science on which these
approaches are based upon. It is in this context the relevance of Bachelard?s
philosophy of science and epistemology can be seen to the problem of
understanding, or to put it in another way, to the solution of mentioned
methodological approaches? shortcomings.

Leonora Carrington. Frente a la desestructuración / Leonora Carrington. Facing the disruption
Authors: De la Fuente Rocha Eduardo
Published: July 2017

En el presente trabajo se busca un acercamiento al conocimiento psíquico de la artista Leonora Carrington. Analizar a un personaje tan complejo no es sencillo, porque las facetas que presenta el desarrollo de su personalidad son múltiples. Aunado a ello está la dificultad para encontrar bibliografía que hable extensamente de su vida, sobre todo de la segunda parte —después de 1942—. Para revisar el análisis de su psiquismo se han tomado dos fuentes: la biográfica y la autobiográfica. A través de este análisis puede observarse la evolución psíquica que la artista logró, lo que permite un mejor entendimiento al legado que su trabajo dejó a la humanidad.
