Approaches to Drug Sample Differentiation. III: A Comparative Study of the Use of Chiral and Achiral Capillary Column Gas Chromatography/Mass Spectrometry for the Determination of Methamphetamine Enantiomers and Possible Impurities
Authors: Liu JH , Ku WW , Tsay JT , Fitzgerald MP , Kim S
Published: August 2015

A gas chromatograph/mass spectrometer (GC/MS) system equipped with a chiral and an achiral capillary column is used to analyze control methamphetamine, an illicit methamphetamine preparation (“White Cross”), and a simulated illicit methamphetamine synthesis product. Samples are derivatized with N-trifluoroacetyl-l-prolyl chloride (I-TPC) before the GC/MS analysis. The results obtained lead to the conclusion that the resolution on an achiral column is adequate for the determination of methamphetamine enantiomers and impurities, providing the enantiomeric impurity of the l-TPC is known. Four new possible by-products of methamphetamine preparations were identified in the simulated illicit methamphetamine synthesis product.

Authors: Lyter AH
Published: August 2015

High pressure liquid chromatography (HPLC) was used to analyze several samples of ball pen ink. Analytical parameters were developed to analyze the various constituents of ball pen ink, both qualitatively and quantitatively. Different ball pen ink formulations were examined, as were batch samples of a single formulation. HPLC has proved to be useful in the examination of ball pen ink, allowing for differentiation of formulations and batches of the same formulation.
The U.S. Postal Money Order As a Questioned Document
Authors: Muehlberger RJ
Published: August 2015

The U.S. Postal Money Order is a negotiable instrument widely used by the general public for conducting financial transactions. The integrity of this document has occasionally been violated by those individuals bent on criminal intent. Criminal activities such as counterfeiting, altering, and raising have been used to derive illicit gain. Knowledge of the production methods of genuine postal money orders and the proper manner in which they are issued to customers is essential in detecting the fraudulent money order. Some of the physical properties of the postal money order, as specified by the U.S. Postal Service, are presented in this paper, as are characteristics of the money order properly issued through the data recorder. Examination procedures, which can be effectively used by the document examiner to perceive those characteristics of the U.S. Postal Money Order that are indicative of genuineness, are discussed.
Defining Malingering
Authors: Gorman WF
Published: August 2015

Malingering, also called shamming illness or goldbricking, is the false and fraudulent simulation or exaggeration of physical or mental disease or defect, performed in order to obtain money or drugs or to evade duty or criminal responsibility, or for other reasons that may be readily understood by an objective observer from the individual's circumstances, rather than from learning the individual's psychology. Malingering is seen in apparently normal children, students, test subjects, spouses, and adults. It is not a mental disorder. Malingering may coexist with the antisocial personality disorder, with various factitious disorders, such as the Ganser Syndrome and the Munchausen Syndrome, with the hysterias and with traumatic neuroses and other mental disorders. A review of definitions and a medicolegal discussion are presented. Malingering is an act, which is distinguished from a legal or mental status. Failure to distinguish act from status accounts for the wide disparities in definitions of malingering.

The Use of Marihuana, Ethanol, and Other Drugs Among Drivers Killed in Single-Vehicle Crashes
Authors: Owens SM , McBay AJ , Cook CE
Published: August 2015

Marihuana, ethanol, and other drugs are considered by many to be detrimental to the safe operation of motor vehicles. However, direct epidemiological evidence for this belief exists only for ethanol. The goal of this investigation was to determine the incidence of the psychoactive ingredient of marihuana, Δ9-tetrahydrocannabinol (THC), along with ethanol and other drugs in blood specimens from a carefully defined population of dead drivers. Although THC and other drugs were present in a small number of the blood specimens, the large number of specimens that had high blood ethanol concentrations indicated that alcohol is still the major drug affecting highway safety.
The Application of Linear Regression to Range-of-Fire Estimates Based on the Spread of Shotgun Pellet Patterns
Authors: Heaney KD , Rowe WF
Published: August 2015

A series of shotgun pellet patterns were fired at ranges that varied from 3.9 to 15.2 m (10 to 50 ft) using a 12-gauge cylinder-bored shotgun firing No. 2 chilled shot cartridges. The spreads of the pellet patterns were measured in two ways: the radius of the smallest circle that would enclose the entire pattern was measured with a transparent overlay and the square root of the area of the smallest rectangle that would enclose the pattern was calculated. Linear regression analysis was applied to sets of data for shots at three, five, and nine ranges. For both measures of pattern spread the linear regression gave correlation coefficients greater than 0.99, indicating that a linear relationship existed between the measures of the pattern spreads and the range of fire. The confidence intervals for range-of-fire estimates at the 95% confidence level were calculated for each set of data. As expected, increasing the number of test-fired patterns decreases the confidence interval and so improves the range-of-fire estimates obtained from the test-fired patterns.
A Review of The Cross and the Shroud
Authors: Froede JA
Published: August 2015

With the recent interest developing around the Shroud of Turin this book is a timely addition to a historical subject that has continued to capture peoples' imagination over the centuries. However, while the author eminently utilizes the texts that would concern him most as a forensic pathologist, it would seem to me that he forgets to use the discipline of biblical exegesis which can be just as exacting and demanding as any forensic science. In any biblical study it is necessary to cover the entire passage or passages by carefully examining the words and structure of the historical manuscripts to determine their meaning and to use the entire story as it appears in Scripture. Any other method is called proof-texting, in other words, eisegesis or using scripture to support your point. Dr. Zugibe is to be congratulated on his usage of Scripture in approaching the pathology of the death of Jesus Christ. What I find omitted to a great extent is “the rest of the story.”
A Review of Digging Up Bones
Authors: Maples WR
Published: August 2015

The introduction to the second edition (1972) of Digging Up Bones stated that “Bones are commonly an embarrassment to archaeologists” Digging Up Bones was written to alleviate the embarrassment or problem caused by bones when found by the archaeologist. It is written for a nonspecialist in the analysis of human skeletal material. Moreover, it seems to have been written primarily for the archaeologist working at sites in Britain. It was intended to give a” basic knowledge of the human skeleton “which” is quite within the reach of those without anatomical training, whether adult archaeologists or schoolboy amateur.” The author has always achieved this stated objective admirably.

Distribution of Cimetidine in Postmortem Tissues
Authors: Berg MJ , Lantz RK , Schentag JJ , Vern BA
Published: August 2015

The postabsorptive distribution of cimetidine is described. Assays by high pressure liquid chromatography (HPLC) of postmortem samples of cerebrospinal fluid, serum, and solid tissues were used to determine pharmacokinetic parameters as well as mean tissue: serum concentration (T:S) ratios in seven patients with renal and liver dysfunction. Correlations were calculated between the T:S ratio and the volume of distribution, and between the T:S concentration ratio and the time of sampling after death. The highest T:S ratios occurred in the eliminating organs, the liver and kidneys, and the lowest in fat. As the time of autopsy increased after death, the T:S ratios decreased.
A New Silicone Rubber Casting Material Designed for Forensic Science Application
Authors: Ojena SM
Published: August 2015

The need for an improved silicone rubber casting material has been evident for years. Products currently available must usually be coated or colored to make them opaque so that fine detail can be microscopically observed. A new product manufactured in Sweden has properties that make it superior to other casting materials currently available. Visibility of detail in casts made from shallow marks is dramatically increased because of its reflective properties and uniform opacity. Besides the usual tool mark applications, the material has been found useful in the comparison of firing pin impressions where lighting is a problem. It is beneficial in the examination of shiny surfaces such as extractor marks on cartridge casings and on plastic surfaces.

A Review of Practical Homicide Investigation: Tactics, Procedures, and Forensic Science Techniques
Authors: McCarty VO
Published: August 2015

The author of this publication initially deserves recognition for an organizational structure whereby chapters are arranged in the same sequence as the duties that develop during any well managed homicide investigation. Difficulty is created by the limitations of a book devoted totally to homicide investigation. Broad knowledge of evidence collection and preservation, as well as investigation of deaths other than homicide, is available to the homicide investigator through other publications. These topics receive inadequate coverage in this volume.
Liquid Chromatographic Analysis of Promethazine and Its Major Metabolites in Human Postmortem Material
Authors: Allender WJ , Archer AW
Published: August 2015

A method is described for the determination of promethazine and some of its major metabolites in postmortem specimens by enzymic digestion followed by high-pressure liquid chromatography of the extracts using a cyano-bonded (μ-Bondapak®-CN) silica column packing and a mobile phase consisting of methanol, water, and n-octylamine (adjusted to pH 8). The system will separate and quantitate promethazine sulphoxide, desmonomethyl promethazine, didesmethyl promethazine, and promethazine. Pericyazine (2-cyano-10-[3-(4-hydroxypiperidino)propyl] phenothiazine) was used as internal standard. The parent drug and metabolites were extracted from a enzyme digested tissue homogenates with ethyl acetate using a simple, single micro-extraction procedure. The method was applied to four cases of fatal poisoning involving promethazine ingestion.

Published: August 2015

A sexual assault case was received in the laboratory. Upon examination, a small bloodstain was located on a bed sheet that was recovered from the defendant's motel room. Typing the whole blood samples from the defendant and the victim revealed that both blood samples exhibited identical phenotypes in eleven different genetic markers. Gm(1) and Gm(2) analysis was then performed on the two whole blood samples which provided discrimination between the two parties.
The Anonymous Letter Writer—A Psychological Profile?
Authors: Casey-Owens M
Published: August 2015

Anonymous letters fall into many categories—threats, obscene messages, racial slurs, extortion demands, guilty conscience statements, stool pigeon letters, robbery or burglary notes, and so forth. These are examined by the document examiner for any information that may lead to the identity of the writer. Such examinations involve unusual aspects of paper or envelopes, watermarks, detection of indented impressions, and so on, and also a comparison with previous anonymous submissions. Several cases will be discussed where, additionally, psychological profiles of the writer were produced by a psychiatrist and a psychologist, based upon the content of the letters.

Authors: Scott ML , Cole JK , McKay SE , Golden CJ , Liggett KR
Published: August 2015

Persons who had been arrested for sexual assault were administered the Luria-Nebraska Neuropsychological Battery and the results compared to a group of normal controls. The sexual assaulters performed significantly worse on 7 of the 14 scales of the battery. The data were then broken down into three groups: (1) those who had forcibly assaulted postpubescent victims, (2) those subjects who had sexually molested a prepubescent child, and (3) normal controls. A discriminant analysis correctly classified 68% of the subjects on the basis of their neuropsychological performance alone.
Human Pulmonary Histopathological Changes from Marijuana Smoking
Authors: Morris RR
Published: August 2015

Thirteen individuals ranging in age from fifteen to forty years, who were known smokers of marijuana, all of whom died suddenly, were autopsied as coroner's cases. The pulmonary histopathologie changes revealed light to heavy infiltrations of pigmented monocytes within alveoli as well as varying degrees of monocytic and lymphocytic infiltration into the interstitium of the lungs. The intensity of the pulmonary infiltrate appears to be dose related. This report calls attention to the accelerated pathological changes in the lungs from marijuana smoking as compared to tobacco smoking leading to pulmonary scarring, emphysema, and eventual chronic obstructive pulmonary discase.
Investigation of Hot Air Balloon Fatalities
Authors: McConnell TS , Smialek JE , Capron RG
Published: August 2015

The rising popularity of the sport of hot air ballooning has been accompanied by several recent incidents, both in this country and other parts of the world, where mechanical defects and the improper operation of balloons have resulted in several fatalities. A study was conducted to identify the location and frequency of hot air ballooning accidents. Furthermore, the study attempted to identify those accidents that were the result of improper handling on the part of the balloon operators and those that were related to specific defects in the construction of the balloon. This paper presents a background of the sport of hot air ballooning, together with an analysis of the construction of a typical hot air balloon, pointing out the specific areas where defects may occur that could result in a potential fatal balloon crash. Specific attention is given to the two recent balloon crashes that occurred in Albuquerque, NM, hot air balloon capital of the world, and that resulted in multiple fatalities.

Fatal Occupational Accidents—The Five-Year Metro Dade County Experience, 1979–1983
Authors: Copeland AR
Published: August 2015

A study of fatal occupational accidents in Metropolitan Dade County between the years 1979 and 1983 was performed from the case files of the office of the medical examiner. A total of 147 cases were collected and were subdivided into 25 traffic-related and 122 nontraffic-related cases. Cases were then analyzed as to age, race, sex, cause of death, alcohol, toxicology, scene circumstances, and who was at fault in the accidental fatality. Traffic-related fatalitics, comprising 17% of the cases, were young white males, commonly less than 45 years of age, who died of multiple injuries in the majority of instances while working as drivers on tractor trailers, migrant farms, or fruit produce trucks. The most common scenario was a vehicle-vehicle collision in which seat belts were not used and the decedent or the decedent's driver was at fault. Nontraffic-related fatalities, comprising 83% of the cases, were likewise white males, commonly less than 45 years of age, who died of multiple injuries in the majority of instances as construction workers or as loading/forklift operators. The most common scenario was one in which alcohol or drugs were not involved. While the “fault” was unassignable in the majority of cases, in those in which it could be, the deceased was at fault approximately half the time with the company or others at fault the other half.

Authors: Niwaguchi T , Kanda Y , Kishi T , Inoue T
Published: August 2015

A radioimmunoassay was developed for the determination of d-methamphetamine in urine. Antiserum to d-methamphetamine was prepared in rabbits by immunization with d-N-4-aminobutylmethamphetamine conjugated with bovine serum albumin, d-1-[3H]-Methamphetamine was used as a labeled compound for radioimmunoassay. The specificity of the antibody against d-methamphetamine was determined by cross-reaction studies with optical isomers of methamphetamine and its analogs. The antibody was specific for d-methamphetamine and exhibited no significant cross-reaction with thel-isomers. This stereoselective assay was applied to determination of d-methamphetamine excreted in urine after oral administration of d- or dl-methamphetamine to rats.

Individualization of Automobile Engine Oils I: The Introduction of Variable Separation Synchronous Excitation Fluorescence to Engine Oil Analysis
Authors: Kubic TA , Lasher CM , Dwyer J
Published: August 2015

Automobile lubricants are frequently encountered at the scene of a crime and are submitted along with standards from the defendant's vehicle in order to establish common origin. The measurement of the total visible fluorescence by emission, synchronous excitation emission, and variable separation synchronous excitation (VSSE) spectra has been shown to individualize motor oils to a high degree. Spectra obtained from specimens at liquid nitrogen temperature increased the discrimination value of these techniques. The data obtained on 61 automobile lubricants is presented and conclusions discussed with particular emphasis on the recently developed VSSE technique.
Efficient Endocytic Uptake and Maturation in Drosophila Oocytes Requires Dynamitin/p50
Authors: Liu Guojun , Sanghavi Paulomi , Bollinger Kathryn E , Perry Libby , Marshall Brendan , Roon Penny , Tanaka Tsubasa , Nakamura Akira , Gonsalvez Graydon B
Published: August 2015

Dynactin is a multi-subunit complex that functions as a regulator of the Dynein motor. A central component of this complex is Dynamitin/p50 (Dmn). Dmn is required for endosome motility in mammalian cell lines. However, the extent to which Dmn participates in the sorting of cargo via the endosomal system is unknown. In this study, we examined the endocytic role of Dmn using the Drosophila melanogaster oocyte as a model. Yolk proteins are internalized into the oocyte via clathrin-mediated endocytosis, trafficked through the endocytic pathway, and stored in condensed yolk granules. Oocytes that were depleted of Dmn contained fewer yolk granules than controls. In addition, these oocytes accumulated numerous endocytic intermediate structures. Particularly prominent were enlarged endosomes that were relatively devoid of Yolk proteins. Ultrastructural and genetic analyses indicate that the endocytic intermediates are produced downstream of Rab5. Similar phenotypes were observed upon depleting Dynein heavy chain (Dhc) or Lis1. Dhc is the motor subunit of the Dynein complex and Lis1 is a regulator of Dynein activity. We therefore propose that Dmn performs its function in endocytosis via the Dynein motor. Consistent with a role for Dynein in endocytosis, the motor colocalized with the endocytic machinery at the oocyte cortex in an endocytosis-dependent manner. Our results suggest a model whereby endocytic activity recruits Dynein to the oocyte cortex. The motor along with its regulators, Dynactin and Lis1, functions to ensure efficient endocytic uptake and maturation.

Authors: Naya Mª Cristina , Soneira Carlos , Mato Mª Dorinda , De la Torre Enrique
Published: August 2015

Hoy ya es comúnmente aceptado que las Matemáticas son una materia cuyo proceso de enseñanza-aprendizaje guarda una estrecha relación con cuestiones afectivas, hasta el punto de generar sentimientos de miedo, inseguridad, ansiedad y bajo autoconcepto que pueden trasladarse y trasmitirse de las facultades de formación de docentes a las aulas de enseñanza obligatoria. Así, la finalidad de este trabajo consiste en la elaboración y validación  de un cuestionario que permite evaluar las actitudes hacia las matemáticas de los futuros docentes de Educación Primaria. El cuestionario está formado por 19 ítems con cinco opciones de respuesta tipo Likert. La muestra estuvo formada por 307 estudiantes de los cuatro cursos del Grado en Educación Primaria de la Facultad de Ciencias de la Educación de la Universidad de A Coruña. La validez y fiabilidad del cuestionario se establecen utilizando técnicas estadísticas y empleando el paquete estadístico IBM SPSS Statistics v.21.0. Se obtuvo un Alfa de Cronbach de .92; y se realizó un análisis factorial exploratorio obteniéndose tres factores: Percepción del profesor de matemáticas por parte del alumnado (con nueve ítems), Agrado hacia las matemáticas (con seis ítems) y Percepción que tiene el alumnado de su competencia matemática (cuatro ítems). Los resultados permiten establecer que el cuestionario tiene una consistencia interna suficiente para ser utilizado en la evaluación de las actitudes de los futuros docentes sobre las matemáticas, la clase y el profesor.

Authors: Verona Regina Bellan , Beal Cesar , Silva Alex De Lara , Lajus Cristiano Reschke
Published: August 2015

O presente trabalho teve como objetivo avaliar a influência de doses de nitrogênio na produtividade do milho silagem em três densidades de semeadura. Utilizou-se delineamento experimental de blocos ao acaso em arranjo fatorial (3x4) com quatro repetições, sendo três densidades de semeadura (5, 7 e 10 sementes.m-1, totalizando 62500, 87500 e 125000 plantas.ha-1) e quatro doses do adubo nitrogenado (0, 50%, 100% e 150% da dose recomendada, ou seja, 0, 95, 190, 285 kg de nitrogênio (N).ha-1). As variáveis respostas avaliadas foram estatura da inserção da espiga, comprimento da espiga, diâmetro da espiga e produtividade (kg.ha-1). Os dados coletados foram submetidos à Anova pelo teste F e as diferenças entre médias foram comparadas pelo teste de Tukey (P≤0,05). Para as variáveis estatura da inserção da espiga, comprimento e diâmetro da espiga, a Anova revelou efeito significativo do fator doses de N. Em relação ao fator densidade, houve efeito significativo para as variáveis comprimento e diâmetro da espiga. Para a variável produtividade, a Anova revelou efeito significativo da interação do fator doses de N e densidades. A estatura de inserção de espiga foi maior com a aplicação de doses crescentes de N. O comprimento de espiga aumenta com a aplicação de doses crescentes de N e diminui com densidades maiores de semeadura. O maior diâmetro de espiga foi obtido na dose de 95 kg de N.ha-1 e densidade de 7 sementes.m-1. A dose de 285 kg de N.ha-1 na densidade de 10 sementes.m-1 foi a interação que apresentou a maior produtividade.

Palavras-chave: Silagem de milho. Densidade de semeadura. Adubação nitrogenada. Produtividade.
DESAFIOS NA PRODUÇÃO DO CONHECIMENTO EM BIOTECNOLOGIA
Authors: Oliveira Marina Mendes , Neto Bezamat Souza , Granjeiro Paulo Afonso
Published: August 2015

Um obstáculo para o Brasil ser reconhecido mundialmente por suas pesquisas em biotecnologia está na burocracia de processos para a aprovação de solicitações, incluindo autorizações de comitês de ética em pesquisa envolvendo seres humanos e animais, o acesso ao patrimônio genético nacional, autorizações estaduais e os pedidos de patentes. O objetivo deste trabalho foi apresentar fluxogramas dos trâmites de acesso às solicitações nas áreas biológicas e afins e as documentações exigidas em cada caso, de modo a servir como fonte de consulta para os pesquisadores na prática. Em razão do excesso de formulários, prazos, entre outras documentações regulamentares, existem resultados desfavoráveis relacionados à produção nacional científica, incluindo a produção de patentes nacionais. Embora a regularização governamental sobre o envolvimento de seres humanos e animais em pesquisas, o acesso ao patrimônio genético e o pedido de patentes sejam essenciais para a preservação da biodiversidade do país, a prevenção de danos e o respeito à propriedade, existem alguns entraves que geram reflexos negativos no crescimento científico nacional.

A crescente evolução dos mercados e das tecnologias de informação tem moldado um cenário de mudanças drásticas nos regulamentos contábeis. Um fato que marcou a contabilidade no Brasil nos últimos anos foi o processo de convergência às normas internacionais de contabilidade, instituído pela Lei n. 11.638/2007, que trouxe consigo novos padrões a serem seguidos. A divulgação de ativos intangíveis foi um deles, tornando-se obrigatória para as companhias de capital aberto. Este estudo teve como objetivo avaliar o nível de divulgação de informações relativas a ativos intangíveis em empresas do setor Financeiro e Outros listadas na BM&FBovespa, entre os anos 2010 e 2012. A pesquisa caracteriza-se como descritiva, documental e quantitativa, compreendendo uma amostra de 34 empresas financeiras. O método aplicado foi a estatística descritiva e a regressão linear múltipla a partir dos dados coletados do check list elaborado com base nos requisitos de divulgação do CPC 04. Os resultados denotam que o nível de divulgação dos intangíveis por parte das empresas investigadas é baixo. Além disso, o tamanho da empresa é a única variável testada que explica de modo significativo a evidenciação dos ativos intangíveis.

A Teoria Institucional centra seus objetivos na tentativa de elucidar como as organizações se tornam tão homogêneas e como ocorre seu processo de legitimação na sociedade. No âmbito de mudanças organizacionais, procura entender o processo de desinstitucionalização de determinadas práticas para institucionalização de novas. Dessa maneira, o objetivo deste trabalho foi analisar as inovações tecnológicas (adoção de tecnologia) empregadas no ensino de graduação em Administração sob a ótica da Teoria Institucional. Para tanto, foi realizada uma pesquisa qualitativa, por meio do método de estudo de caso, sendo realizadas quatorze entrevistas em profundidade, mediante um roteiro semiestruturado. Alguns resultados puderam ser observados, como: resistência à desinstitucionalização de práticas e pressões por parte dos participantes do processo. A utilização de tecnologias para melhora da eficiência das organizações parece ser legitimada pela sociedade; para tanto, a mudança na estrutura da organização confirma as práticas referenciadas na Teoria Institucional.

GOVERNANÇA CORPORATIVA EM COOPERATIVAS AGROPECUÁRIAS: UM MODELO DE CLASSIFICAÇÃO COM APLICAÇÃO DA FERRAMENTA WALK / Corporate Governance in agricultural cooperatives: a classification model with application tool WALK
Authors: Silva Robson Faria , Souza Alceu , Silva Wesley
Published: August 2015

Com a complexidade das organizações e dos sistemas econômicos, os proprietários de capital delegaram a gestão a grupos profissionais, separando, assim, a propriedade e o controle. Ao adotar essa prática,  essa  separação  possibilita a existência de comportamentos oportunistas com ações e decisões orientadas a benefícios do grupo controlador e em detrimento dos proprietários do capital. Esse assunto, denominado Teoria da Agência, tem sido exaustivamente estudado. A transparência das ações e decisões do controlador, via Governança Corporativa, é uma das estratégias adotadas para a defesa dos interesses dos proprietários de capital.  No caso de cooperativas em que cada acionista tem direito a um voto e na qual quase sempre há diferença significativa em conhecimento de gestão de negócios complexos entre os cooperados e o grupo que deve exercer o controle, a Governança Corporativa assume conotações específicas. Assim, este trabalho propõe, via análise multicritério, um modelo de classificação do grau de Governança Corporativa em cooperativas agropecuárias. Trata-se de uma pesquisa aplicada quanto à sua natureza; descritiva e propositiva quanto ao seu objetivo; de pesquisa de campo quanto à estratégia de abordagem do problema; de pesquisa documental e entrevistas semiestruturadas com amostragem por conveniência quanto aos procedimentos técnicos de coleta de dados e quantitativa quanto ao ferramental de análise de dados. A pesquisa foi aplicada a 20  cooperativas do Estado do Paraná que responderam a questões ligadas aos princípios de Governança Corporativa: Transparência; Equidade; Prestação de Contas e Responsabilidade Corporativa. Os resultados foram a construção de um modelo de classificação de cooperativas, por meio da utilização da análise multicritério ligada ao método Preference Ranking Organization Method for Enrichment Evaluations (Promethee) dinamizado pelo software WALK[ER], que possibilitou identificar os níveis de Governança Corporativa das cooperativas. A formação de clusters indica o distanciamento entre as cooperativas e as dimensões, em 3D. De maneira geral, apontaram baixa adesão às práticas de Governança.

Towards analogy-based reasoning in semantic network
Authors: Stojkovic Milos , Trifunovic Milan , Misic Dragan , Manic Miodrag
Published: August 2015

In this paper an approach in realization of analogy-based reasoning in
semantic networks is presented. New semantic model, called Active Semantic
Model (ASM), was used. Core of the process is performed by ASM?s association
(semantic relation) plexus upgrading procedure based on recognition and
determining similarity between association plexuses. Determining similarity
between association plexuses is performed by recognition of topological
analogy between association plexuses. ASM responds to unpredicted input by
upgrading new association plexus modeled on remainder of the context whose
subset is recognized as topologically analogous association plexus.
Challenges in Antibody Development against Tn and Sialyl-Tn Antigens

Published: August 2015

The carbohydrate antigens Tn and sialyl-Tn (STn) are expressed in most carcinomas and usually absent in healthy tissues. These antigens have been correlated with cancer progression and poor prognosis, and associated with immunosuppressive microenvironment. Presently they are used in clinical trials as therapeutic vaccination, but with limited success due to their low immunogenicity. Alternatively, anti-Tn and/or STn antibodies may be used to harness the immune system against tumor cells. Whilst the development of antibodies against these antigens had a boost two decades ago for diagnostic use, so far no such antibody entered into clinical trials. Possible limitations are the low specificity and efficiency of existing antibodies and that novel antibodies are still necessary. The vast array of methodologies available today will allow rapid antibody development and novel formats. Following the advent of hybridoma technology, the immortalization of human B cells became a methodology to obtain human monoclonal antibodies with better specificity. Advances in molecular biology including phage display technology for high throughput screening, transgenic mice and more recently molecularly engineered antibodies enhanced the field of antibody production. The development of novel antibodies against Tn and STn taking advantage of innovative technologies and engineering techniques may result in innovative therapeutic antibodies for cancer treatment.
RETRACTED: Evidence of Coal-Fly-Ash Toxic Chemical Geoengineering in the Troposphere: Consequences for Public Health
Authors: Herndon J.
Published: August 2015

The widespread, intentional and increasingly frequent chemical emplacement in the troposphere has gone unidentified and unremarked in the scientific literature for years. The author presents evidence that toxic coal combustion fly ash is the most likely aerosolized particulate sprayed by tanker-jets for geoengineering, weather-modification and climate-modification purposes and describes some of the multifold consequences on public health. Two methods are employed: (1) Comparison of 8 elements analyzed in rainwater, leached from aerosolized particulates, with corresponding elements leached into water from coal fly ash in published laboratory experiments, and (2) Comparison of 14 elements analyzed in dust collected outdoors on a high-efficiency particulate air (HEPA) filter with corresponding elements analyzed in un-leached coal fly ash material. The results show: (1) the assemblage of elements in rainwater and in the corresponding experimental leachate are essentially identical. At a 99% confidence interval, they have identical means (T-test) and identical variances (F-test); and (2) the assemblage of elements in the HEPA dust and in the corresponding average un-leached coal fly ash are likewise essentially identical. The consequences on public health are profound, including exposure to a variety of toxic heavy metals, radioactive elements, and neurologically-implicated chemically mobile aluminum released by body moisture in situ after inhalation or through transdermal induction.
Manganese-based Permanent Magnets
Authors: Baker Ian
Published: August 2015

There is a significant gap between the energy product, BH, where B is the magnetic flux density and H is the magnetic field strength, of both the traditional ferrite and AlNiCo permanent magnets of less than 10 MGOe and that of the rare earth magnets of greater than 30 MGOe. This is a gap that Mn-based magnets could potentially, inexpensively, fill. This Special Issue presents work on the development of both types of manganese permanent magnets. Some of the challenges involved in the development of these magnets include improving the compounds’ energy product, increasing the thermal stability of these metastable compounds, and producing them in quantity as a bulk material.[...]
Non-Linear Piezoelectric Actuator with a Preloaded Cantilever Beam

Published: August 2015

Piezoelectric actuation is widely used for the active vibration control of smart structural systems, and corresponding research has largely focused on linear electromechanical devices. This paper investigates the design and analysis of a novel piezoelectric actuator that uses a piezoelectric cantilever beam with a loading spring to produce displacement outputs. This device has a special nonlinear property relating to converting between kinetic energy and potential energy, and it can be used to increase the output displacement at a lower voltage. The system is analytically modeled with Lagrangian functional and Euler–Lagrange equations, numerically simulated with MATLAB, and experimentally realized to demonstrate its enhanced capabilities. The model is validated using an experimental device with several pretensions of the loading spring, therein representing three interesting cases: a linear system, a low natural frequency system with a pre-buckled beam, and a system with a buckled beam. The motivating hypothesis for the current work is that nonlinear phenomena could be exploited to improve the effectiveness of the piezoelectric actuator’s displacement output. The most practical configuration seems to be the pre-buckled case, in which the proposed system has a low natural frequency, a high tip displacement, and a stable balanced position.
