INTERACCIÓN TROFOBLASTO-EPITELIO UTERINO EN LA FORMACION DE LA PLACENTA EPITELIOCORIAL, ALPACAS
Authors: OLIVERA MAROCHO LUIS V.
Published: July 2015

Estudios reproductivos en Camélidos Sudamericanos son escasos. Para entender el desarrollo y fisiología celular de la interacción trofoblasto-epitelio uterino en la formación de la placenta epiteliocorial de alpacas fueron examinados muestras desde los 150 días a término de la preñez. Las evaluaciones morfológicas fueron realizadas utilizando técnicas para microscopía de luz, microscopia electrónica de barrido y transmisión y localizaciones histoquímicas de fosfatasa ácida y alcalina. A través de la preñez hubo un progreso incremento en la formación de pliegues con depresiones profundas de la mucosa uterina mostrándose muy delgada el endometrio. Las glándulas uterinas mostraron reacción positiva para PAS y fosfatasa ácida. Las células trofoblásticas no gigantes exhibieron fosfatasa alcalina. En la abertura de las glándulas, el corion formó típicas areolas, donde el trofoblasto mostró reacción positiva a la fosfatasa acida y PAS. La interface trofoblasto-epitelio uterino exhibió una compleja interdigitación de microvellosidades, donde la reacción a la fosfatasa alcalina fue muy marcada. Los capilares coriónicos progresivamente indentan a las células trofoblásticas. Estos datos sugieren que a pesar de ser una placenta epiteliocorial, de la alpaca, diversos tipos celulares del trofoblasto y áreas especializadas de la interface maternofetal poseen funciones microregionales, especializadas en nutrición histotrófica, producción hormonal e intercambio molecular.

Published: July 2015

Hoy en día los peruanos sufragamos en las elecciones de forma obligatoria por ley y de no hacerlo somos susceptibles de incurrir en el pago de una multa, lo que resulta inconsistente ya que el voto es un derecho y como tal deberíamos tener la facultad de decidir el hecho de ejercerlo o no, como en otros países de la región, para modificar la actual situación del voto electoral, asumida por disposición constitucional; se debe primeramente reformar la Constitución del Estado mediante una ley de reforma respecto a la votación obligatoria para cambiarla por un ejercicio de votación de carácter facultativo, de otro lado debemos empezar a implementar de manera mas eficaz el voto electrónico que la ley Nº 28581, lo creo la misma que data desde el año 2006 y que recientemente ahora en las elecciones programadas para el 05 octubre de 2014, se empezará a implementar a paso muy lento, por lo que debemos tomar conciencia electoral y comenzar a implementarla descentralizadamente y no centralistamente, como es el caso que en solamente siete distritos de Lima se efectuará el voto electrónico, sin haber tomado en cuenta a las capitales de otras Regiones del interior del País; comenzar a prepararnos para las elecciones Generales del 2016.

Con la finalidad de evaluar la respuesta clínica de las alpacas sometidas a un protocolo de anestesia total intravenosa en base a la combinación de xilacina, ketamina y fentanilo para canulacion del primer compartimento en alpacas, se determinaron variables fisiológicas, anestesiológicas y monitoreo anestésico. Se utilizaron cinco alpacas adultas, clínicamente sanas a las que se administró 0.2 mg/kg de xilacina, 5 mg/kg de ketamina en bolos repetidos y 0.5 µg/kg/hora de fentanilo por infusión a ritmo constante. Las variables y el monitoreo anestésico se midieron cada 5 y 10 min. Las medias y desviación estándar para la frecuencia cardiaca fueron 55.74 ± 5.57 latidos/min, frecuencia respiratoria de 10.31 ±
0.91 ciclos/min, frecuencia de pulso 60.00 ± 5.22 pulsaciones/min y saturación de oxigeno de 91.47 ± 5.63 %, con variaciones durante todo el periodo anestésico. La Presión arterial sistólica, diastólica y media fueron 146.40 ± 14.86, 85.70 ± 6.90 y 108.50 ± 7.53 mm Hg respectivamente. El tiempo de inducción fue 55.0 ± 8.7 s, el tiempo de latencia 79.0 ± 4.2 min y el tiempo de recuperación 11.0 ± 4.0 min. Las alpacas estuvieron en un plano anestésico superficial a quirúrgico con disminución de las respuestas motora, cardiovascular y respiratoria dosis dependiente, el tono muscular fue moderado y el reflejo palpebral permanente. La respuesta anestésica del protocolo fue moderado y la analgesia aceptable. La fistulación por compartimentotomia diferida y canulación del primer compartimento con una cánula de material polipropileno fue biocompatible y viable.

Published: July 2015

El cambio climático viene alterando las condiciones del clima local; siendo los parámetros más sensibles las temperaturas extremas y las precipitaciones pluviales; por ende se investiga los efectos del cambio climático en la agricultura de la cuenca Ramis evaluando el comportamiento de las variables climáticas y su consecuencia en la actividad agrícola del altiplano peruano. Se trabajó con las series históricas de temperaturas extremas y precipitaciones pluviales de 46 años de las diez estaciones meteorológicas seleccionados en base a longitud de las series, estaciones con datos faltantes y la consistencia, posteriormente se sistematizó, corrigió y completó en base del análisis de homogeneidad, luego se determinó las tendencias con las pruebas no paramétricas y paramétricas con 0.01, 0.05 y 0.10 niveles de significancia y análogamente la información de rendimientos de los cultivos. Las temperaturas máximas tienden a incrementar en 0.04ºC anualmente, las medias muestran un incremento anual de 0.025ºC con evidencia leve y las mínimas no muestran cambios significativos; mientras que las precipitaciones pluviales tienden a disminuir, y estos generan impactos significativos en los cultivos. Finalmente, que el cambio climático viene afectando a los parámetros de temperaturas y precipitaciones, y esto influye negativamente en el rendimiento de los cultivos en el ámbito de estudio así coinciden varios investigadores.

Published: July 2015

En el presente trabajo se exponen las mediciones de la radiación ultravioleta tipo A; la de tipo B y el INDICE en la ciudad de Upina – Puno. La dependencia entre el INDICE y la radiación ultravioleta fue investigada y se encontró un excelente grado de asociación. Sé observo que el INDICE es 1.6 veces la radiación ultravioleta tipo B, mientras que el INDICE es 3.207 veces el tipo A. Posteriormente en la Universidad Nacional del Altiplano, se ha medido la radiación ultravioleta tipo B para cielos despejados sin nubes. A partir de estos datos se ha estimado el INDICE, notándose un incremento de 5,92 hasta 9,376, desde el 28 de setiembre el 20 de noviembre del 2014. Si se considera la radiación tipo A y el efecto espejo del lago Titicaca, los valores del ÍNDICE son mayores a 12 para el mes de noviembre, que es el valor máximo permitido por la Organización Mundial de la Salud. Para obtener los valores estimados de la radiación ultravioleta tipo A y tipo B en cielos claros, se ha utilizado el modelo parametrico, programado en MATLAB. El modelo explica el comportamiento de la radiación para cielos parciamente nublados, notándose que las características de las nubes pueden aumentar o disminuir dicha radiación

Authors: ESCOBEDO RIVERA JOSE
Published: July 2015

El presente Trabajo fue presentado al «I Encuentro de Egresados de la Escuela Profesional de Nutrición Humana de la Universidad Nacional de Altiplano-Puno», 21-22 de noviembre 2014. Tiene como objetivo explicitar la relación existente entre nuestra actual realidad demográfica y sus implicancias con la salud. Básicamente nos hemos centrado en dos variables: la fecundidad y la mortalidad. La reducción de la fecundidad ha contribuido para disminuir la mortalidad infantil y materna. Entre 1986 y 2013, la fecundidad disminuyó de 4,3 a 2,4 hijos por mujer. También, la mortalidad infantil, presenta niveles diferenciados por características geográficas donde el riesgo de mortalidad infantil es mayor en áreas urbanas y rurales que en Lima Metropolitana, con 24, 16 y 12 defunciones por cada mil nacimientos. La mortalidad materna, que evidencia la exclusión social, muestra que las principales causas de muerte fueron: la hemorragia, que en la Sierra fue de 51,6 y en la Selva 38,4%, y la hipertensión inducida por el embarazo HIE fue más frecuente en la Costa, 38,4%. En cuanto al lugar de ocurrencia del parto los establecimientos de salud públicos fueron más utilizados por mujeres residentes en el área urbana (81,9%) que en el área rural (65,6%). Sobre la asistencia durante el parto para asegurar la salud de la madre y del niño por nacer, el 58,4% de mujeres con un nacido vivo recibieron dos o más dosis de la vacuna antitetánica. El porcentaje de mujeres cuyo parto más reciente fue protegido contra el tétano alcanzó el 80 ,7%.

Un Extracto de Maíz Morado (EMM) se evaluó la eficacia antioxidante en salchichas de cerdo curado cocido y sin curar. Valores deTBARS, evaluación color instrumental y las puntuaciones del panel sensorial se evaluaron. Para salchichas sin curar, EMM al 0,2% fue igual de efectiva que 0,1% de hidroxitolueno butilado (BHT) en la reducción de los valores de TBARS. Del mismo modo, EMM al 0,2% de manera significativa (Pb0.01) redujo los TBARS en embutidos curados. La incorporación de 0,2%en las salchichas EMM produjo mayor (Pb0.05) de color CIE valor de a* es inferior (Pb0.05) L* y b*. Paneles sensoriales no detectaron ninguna diferencia en el color, el olor, el sabor, el aroma y la aceptación general de las salchichas de cerdo sin curar con la adición de 0,2% EMM. Sin embargo, hubo cambios negativos en el color y el olor de embutidos curados, a pesar de que el gusto, sabor, y aceptación global fueron similares. Por lo tanto, los resultados sugieren que la EMM es un antioxidante potencial.
Variação Pluviométrica e Parâmetros Físico-químicos da Água Tratada para Distribuição em Porto Velho, Rondônia
Authors: Bay Márcia
Published: July 2015

O regime pluviométrico do município de Porto Velho capital de Rondônia (Amazônia brasileira) é bastante regular, variando apenas nos três meses mais secos de cada ano (Aw na classificação de Köppen). A qualidade da água neste município é atualmente um fator preocupante, tendo em vista o rápido crescimento demográfico ocorrido nos últimos quatro anos. Este fato se deve aos investimentos federais em um grande complexo hidrelétrico construído no Rio Madeira em Porto Velho (Usinas de Jirau e Santo Antônio). Quanto maior o consumo de água, maior a quantidade de água a ser tratada para a distribuição. A adição de produtos químicos como sulfato de alumínio (Al2 (SO4)3) e cloro (Cl2) para o tratamento da água é feita com base em normas técnicas e a quantidade dos mesmos varia de acordo com o período do ano e o regime pluviométrico local. A variação da quantidade de chuva pode interferir nos valores de parâmetros básicos como pH, Turbidez e Cloro residual da água, sendo a proposta deste trabalho, fazer o comparativo do comportamento destes parâmetros com base na variação das chuvas em Porto Velho. Os dados mostraram uma regularidade nos parâmetros (pH, turbidez e cloro residual)  analisados nos meses com menor precipitação.

Variation Pluviometric, Chemical And Physical Parameters Of Water Treated For Distribution In Porto Velho, Rondônia

Abstract: The rainfall in the city of Porto Velho capital of Rondônia (Brazilian Amazon) is fairly regular , varying only in the three driest months of each year (in the Köppen Aw) . Water quality in this municipality is currently a concern in view of the rapid population growth occurred in the last four years. This is due to the federal investments in a large hydroelectric complex built on the Madeira River in Porto Velho (Plants Jirau and San Antonio) .The higher the water, the greater the amount of water to be treated for distribution. The addition of chemicals such as aluminum sulfate (Al2 (SO4)3) and chlorine (Cl2 ) for the treatment of water is made based on technical requirements and the amount thereof varies depending on the time of year , and rainfall site. Varying the amount of rain can interfere with the basic parameter values such as pH, turbidity and residual chlorine in water, the purpose of this work, make the comparative behavior of these parameters based on the variation of rainfall in Porto Velho. The data showed a regularity in the parameters (pH, turbidity and residual chlorine) analyzed the months with lower precipitation
Evolución de las preferencias políticas y de políticas públicas entre el sector popular y el resto de la sociedad chilena entre 1990 y 2012
Authors: Barrueto Felipe , Navia Patricio
Published: July 2015

La combinación de un rápido crecimiento económico con altos niveles de desigualdad, en el Chile posterior a 1990, permitió el desarrollo de una clase media emergente y la consolidación de diferencias entre los sectores altos y los nuevos sectores medios. El aquí llamado sector popular mejoró sus ingresos y sus expectativas, pero los sectores altos mejoraron aún más. ¿Qué efectos tuvo esto sobre las preferencias e inclinaciones políticas del sector popular y sobre sus prioridades de políticas públicas? ¿Qué tan diferente ha sido su evolución? Aunque al comenzar la nueva fase democrática los sectores medios y bajos prefirieron la Concertación, esa adhesión ha disminuido con el tiempo. Usando datos del Centro de Estudios Públicos, analizamos tanto la evolución del sector popular respecto del resto de la sociedad, como su propia evolución en las preferencias políticas y prioridades de políticas públicas

La política turística y la intervención del Estado. El caso de Argentina
Authors: Schenkel Erica , Almeida García Fernando
Published: July 2015

La escasez de análisis politológicos en torno al turismo se explica por la primacía de la perspectiva económica que concibe al fenómeno como una simple actividad de consumo ligado al sector privado. Sin embargo, la ciencia política es una pieza fundamental para comprender el turismo, dado que proporciona conceptos e instrumentos metodológicos que enriquecen su estudio. Desde esta perspectiva, se analiza la evolución de la política turística argentina teniendo como referencia los modelos de producción económico-turísticos. Se identifican las principales funciones que adquiere el turismo como asunto público en el país siguiendo la evolución de un contexto social, económico y político particular estructurado con base en cánones internacionales vigentes. Finalmente, se aporta un modelo de desarrollo socioeconómico basado en el turismo.
Prevention of Shale Instability by Optimizing Drilling Fluid Performance
Authors: Mkpoikana R. , Dosunmu A. , Eme C.
Published: July 2015

This research work outlines the main results of the shale instability study with respect to shale/ fluid interaction mechanisms, and also analyses the shale strength properties. An approach was undertaken to develop a better understanding of the effects of using polymer drilling fluid on the shale mechanical properties and how to optimize its performance. Wellbore stability in shale is very much influenced by the type of drilling fluid used, here the problems observed were, borehole fluid invasion into the shale, increase in potential pipe sticking, swelling/hydration of shale which results in high level of non-production time (NPT). Different drilling fluids were analyzed for their effects on shale strength. Emphasis here was on the mechanical properties of the shale samples after exposed to different drilling fluids for 24hours. The mud which maintains high compressive strength of the shale is the most preferred (optimum) selection. The shale sample exposed to the polymer drilling fluid shows the lowest strength, from the stress-strain curve. The use of KCl brine in drilling fluids is based on its shale inhibition characteristics as it is thought that the k+ ion provides additional attraction among the clay platelets due to its size and charge. However the shale loses most part of its strength when exposed to the modified polymer drilling muds combined with 5% KCl, 7%, 10% KCl respectively. One of the possible reasons is Kaolinite in the shale. The shale samples will keep more of its original strength when exposed to the modified polymer drilling muds combined with chemical agents with plugging ability to pore throat and micro-fracture. The shale sample exposed to polymer drilling fluid with 10%Nacl, 5% Physical sealing agent and 10% Chemical agent A1 (rich in silica) exhibit the highest strength. From the result of the experiment the drilling fluid density has been reduced immensely, thus the new mud system improves the wellbore stability and keeps the shale formation stable.
Resolving Anomalous Water Based Mud Rheology Challenges Cause Investigation and Treatment
Authors: Erinle Adeyemi , Enyekwe Alfred , Ufomaduh Mirian Kosi
Published: July 2015

Drilling with water based mud (WBM) generally has its green and cost effective advantages but also comes with its own challenges, which raise the need for more vigilance, planning and timely reaction when WBM is to be used for any hole section. On FAQ1X well, the 16″ top hole section was drilled to 9,500fttvd with KCl polymer WBM; while circulating hole clean in preparation for tripping out, erratic mud rheology properties were observed. It took up to 3days to recondition the drilling fluid specifications. An investigation was carried out to explore the possible causes. The behavior bore no similarity to equivalent sections in previously drilled wells, though the mud system was different. The fresh water for building the mud was optimum; the additives were in good condition and within acceptable operating conditions. The analysis for any carbonate contamination by Alkalinity Analysis (which is rather unreliable) gave an indication of possible carbonate contamination though no source of carbonate was detected. The bentonite used was not in excess yet there was an increase in the Cation exchange capacity of the mud. The other source of Low gravity solids is formation solids that have been very well grinded by the bit and dispersed in the mud such that it becomes difficult to separate them from the mud system via the mud cleaning equipment. They lead to severe gelling of the mud and consequently high mud rheology and hole-swabbing tendency. This significant distortion in rheological properties of the mud was as a result of high solid content in the mud and possibly carbonate or bicarbonate. A dilution recipe was developed and applied to tackle both possibilities and the mud properties were restored.
Lean Methods Application to Frontend Petroleum Engineering Project
Authors: Itua Osazua J. , Shamuganathan Gomathi
Published: July 2015

The application of lean methods is credited with successful project delivery in various industries. Organizations are attracted to lean methods because its concept can be customized to project specific requirements to identify and eliminate waste in the value stream. In the petroleum industry, lean has been successfully applied to projects in ‘execute’ and ‘operate’ phases. In spite of this, there is no wide spread application to frontend projects. To realize the opportunity to accelerate first gas date by a year, lean concept was adopted to mature XY field during its frontend phase.

This presentation is aimed at sharing the influence of lean tools on the project and to strengthens the argument that lean can be applied to frontend projects renowned for high task uncertainty compared to projects in ‘operate and execute’ phases in the petroleum industry with low task uncertainty where lean methods currently thrive.
Priming with Energy Drinks May Promote Men's Tolerance of Social Pain
Authors: Karlsson Torulf , Abetkoff Darren , Chiou Wen-Bin
Published: July 2015

In advertising of caffeinated energy drinks, there appears to be a consistent emphasis reinforcing masculine identification. Greater tolerance of social pain in a situation of exclusion is a characteristic particularly identified with masculinity. In this study, we tested the priming
effect of an energy drink on men's social pain tolerance in the situation of experiencing social exclusion in Cyberball, a virtual ball-tossing game. We recruited 93 men who were undergraduate students at a university in Taiwan to participate in an experimental study. Results showed that the
men exposed to a popular caffeinated energy drink (Red Bull) tolerated being excluded from a greater number of throws in Cyberball than did those with a neutral prime or no prime. Induced conformity to masculine norms mediated the link between the energy drink prime and increased tolerance
of social pain. These findings suggest that mere exposure to energy drinks may lead men to behave according to masculine norms in a seemingly unrelated domain.

We analyzed how consumer sensitivity to information requests influences acceptance and recommendation of a banking firm's advertising that is sent via a cellular phone. To this end, the data—based on the respondents from 395 young adults—fit the model well and provided empirical
support for all the hypothesized relationships. The results obtained provide useful information for companies to improve the efficiency of their mobile publicity, together with possible modifications and improvements to their existing commercial strategies. We suggest that information requests
should be carefully chosen to ensure ethical behavior in relation to consumers and to preserve the efficiency of mobile publicity.

Authors: Park Jisung , Shin Soo-Young , Lee Sangmin , No Se-Ri
Published: July 2015

We examined the role of the chief executive officer's (CEO) learning goal orientation in the relationship between human resource management (HRM) practices and organizational creativity in small- and medium-sized enterprises (SME). With data from 64 Korean SME from different respondents
(CEOs and HRM managers), we examined the congruence of messages between formality represented by knowledge-sharing HRM practices and informality symbolized by the CEO's learning goal orientation in fostering organizational creativity. According to the analytical results, appraisal based on
the extent of knowledge sharing enhanced organizational creativity when the CEO's learning goal orientation was high by sending congruent messages but not by monetary reward systems to promote knowledge sharing. The results have important theoretical and practical implications for the fit
between formality/informality and organizational creativity in SME.
Happy to Support: Emotion as a Mediator in Brand Building Through Philanthropic Corporate Sponsorship
Authors: Lee Woo-Young , Hur Youngjin , Sung Minjung
Published: July 2015

The concept of corporate social responsibility (CSR) is very meaningful in a culture such as that of the Republic of Korea, where individual ethics are grounded in Confucianism, which emphasizes humanism and altruism. We examined the mediating role of emotion in the relationships among
participants' perceptions of CSR, their attitude toward philanthropic corporate sponsorship of a sporting event, and of the sponsoring company's brand equity. We conducted a survey with 251 participants in a charitable sports event held in Seoul, South Korea, which was sponsored by a major
Korean company. The results of analysis of the data collected provide an understanding of how strong brand equity of the sponsoring company was generated among participants. The findings also shed light on the mediating role of emotion in the relationship between the company's brand equity
and 2 major participant cognitive factors of attitude toward an event and perception of CSR. Results indicate that sponsoring a charitable sporting event targeted at certain types of consumers can be an effective marketing tool for a company to build brand equity.

Authors: Mori Brenda , Brooks Dina , Norman Kathleen E. , Herold Jodi , Beaton Dorcas E.
Published: July 2015

Purpose: To develop the first draft of a Canadian tool to assess physiotherapy (PT) students' performance in clinical education (CE). Phase 1: to gain consensus on the items within the new tool, the number and placement of the comment boxes, and the rating scale; Phase 2: to explore the face and content validity of the draft tool. Methods: Phase 1 used the Delphi method; Phase 2 used cognitive interviewing methods with recent graduates and clinical instructors (CIs) and detailed interviews with clinical education and measurement experts. Results: Consensus was reached on the first draft of the new tool by round 3 of the Delphi process, which was completed by 21 participants. Interviews were completed with 13 CIs, 6 recent graduates, and 7 experts. Recent graduates and CIs were able to interpret the tool accurately, felt they could apply it to a recent CE experience, and provided suggestions to improve the draft. Experts provided salient advice. Conclusions: The first draft of a new tool to assess PT students in CE, the Canadian Physiotherapy Assessment of Clinical Performance (ACP), was developed and will undergo further development and testing, including national consultation with stakeholders. Data from Phase 2 will contribute to developing an online education module for CIs and students.
Physiotherapy Management of People Diagnosed with de Quervain's Disease: A Case Series
Authors: Rabin Alon , Israeli Tomer , Kozol Zvi
Published: July 2015

Purpose: To report the outcomes of a physiotherapy management approach for de Quervain's disease (DQD), a common hand disorder for which evidence for physiotherapy management is lacking, in 4 consecutive patients with DQD. Methods: Participants underwent a median of eight treatment sessions, consisting of mobilizations with movement, eccentric muscle training, and high-voltage electrical stimulation. Outcomes were assessed with an 11-point numeric pain rating scale (NPRS; range 1–10) and the Disabilities of the Arm, Shoulder and Hand questionnaire (DASH; range 0%–100%). Results: Median NPRS and DASH scores decreased from a baseline of 5 and 48, respectively, to 2.8 and 19 after treatment; at 6-month follow-up, all participants reported minimal pain and disability, but one participant required a corticosteroid injection shortly after discharge from physiotherapy. Conclusions: Overall outcome was considered successful for three of four patients, comparable to the success rate previously reported for corticosteroid injections. A randomized clinical trial evaluating the efficacy of this intervention seems warranted.

Published: July 2015

Biochars are complex heterogeneous materials that consist of mineral phases, amorphous C, graphitic C, and labile organic molecules, many of which can be either electron donors or acceptors when placed in soil. Biochar is a reductant, but its electrical and electrochemical properties are a function of both the temperature of production and the concentration and composition of the various redox active mineral and organic phases present. When biochars are added to soils, they interact with plant roots and root hairs, micro-organisms, soil organic matter, proteins and the nutrient-rich water to form complex organo-mineral-biochar complexes Redox reactions can play an important role in the development of these complexes, and can also result in significant changes in the original C matrix. This paper reviews the redox processes that take place in soil and how they may be affected by the addition of biochar. It reviews the available literature on the redox properties of different biochars. It also reviews how biochar redox properties have been measured and presents new methods and data for determining redox properties of fresh biochars and for biochar/soil systems.
Heat Kernel Embeddings, Differential Geometry and Graph Structure
Authors: ElGhawalby Hewayda , Hancock Edwin
Published: July 2015

In this paper, we investigate the heat kernel embedding as a route to graph representation. The heat kernel of the graph encapsulates information concerning the distribution of path lengths and, hence, node affinities on the graph; and is found by exponentiating the Laplacian eigen-system over time. A Young–Householder decomposition is performed on the heat kernel to obtain the matrix of the embedded coordinates for the nodes of the graph. With the embeddings at hand, we establish a graph characterization based on differential geometry by computing sets of curvatures associated with the graph edges and triangular faces. A sectional curvature computed from the difference between geodesic and Euclidean distances between nodes is associated with the edges of the graph. Furthermore, we use the Gauss–Bonnet theorem to compute the Gaussian curvatures associated with triangular faces of the graph.

Positron emission tomography (PET) combined with magnetic resonance imaging (MRI) is a hybrid technology which has recently gained interest as a potential cancer imaging tool. Compared with CT, MRI is advantageous due to its lack of ionizing radiation, superior soft-tissue contrast resolution, and wider range of acquisition sequences. Several studies have shown PET/MRI to be equivalent to PET/CT in most oncological applications, possibly superior in certain body parts, e.g., head and neck, pelvis, and in certain situations, e.g., cancer recurrence. This review will update the readers on recent advances in PET/MRI technology and review key literature, while highlighting the strengths and weaknesses of PET/MRI in cancer imaging.
Averaged Extended Tree Augmented Naive Classifier
Authors: Meehan Aaron , De Campos Cassio
Published: July 2015

This work presents a new general purpose classifier named Averaged Extended Tree Augmented Naive Bayes (AETAN), which is based on combining the advantageous characteristics of Extended Tree Augmented Naive Bayes (ETAN) and Averaged One-Dependence Estimator (AODE) classifiers. We describe the main properties of the approach and algorithms for learning it, along with an analysis of its computational time complexity. Empirical results with numerous data sets indicate that the new approach is superior to ETAN and AODE in terms of both zero-one classification accuracy and log loss. It also compares favourably against weighted AODE and hidden Naive Bayes. The learning phase of the new approach is slower than that of its competitors, while the time complexity for the testing phase is similar. Such characteristics suggest that the new classifier is ideal in scenarios where online learning is not required.

In this study we design and test a novel solar tracking generation system. Moreover, we show that this system could be successfully used as an advanced solar power source to generate power in greenhouses. The system was developed after taking into consideration the geography, climate, and other environmental factors of northeast China. The experimental design of this study included the following steps: (i) the novel solar tracking generation system was measured, and its performance was analyzed; (ii) the system configuration and operation principles were evaluated; (iii) the performance of this power generation system and the solar irradiance were measured according to local time and conditions; (iv) the main factors affecting system performance were analyzed; and (v) the amount of power generated by the solar tracking system was compared with the power generated by fixed solar panels. The experimental results indicated that compared to the power generated by fixed solar panels, the solar tracking system generated about 20% to 25% more power. In addition, the performance of this novel power generating system was found to be closely associated with solar irradiance. Therefore, the solar tracking system provides a new approach to power generation in greenhouses.

Benzene is a ubiquitous environmental pollutant and an important industrial chemical present in both gasoline and motor vehicle emissions. Occupational human exposure to benzene occurs in the petrochemical and petroleum refining industries as well as in gas-station workers, where it can lead to benzene poisoning (BP), but the mechanisms of BP are not completely understood. In Brazil, a significant number of gas-station service workers are employed. The aim of the present study was to evaluate alterations related to BP and metabolic polymorphisms in gas-station service workers exposed to benzene in the city of Rio de Janeiro, Brazil. Occupational exposure was based on clinical findings related to BP, and metabolic polymorphisms in 114 Brazilian gas-station attendants. These workers were divided into No Clinical Findings (NCF) and Clinical Findings (CF) groups. Neutrophil and Mean Corpuscular Volume (MCV) showed a significant difference between the two study groups, and neutrophil has the greatest impact on the alterations suggestive of BP. The clinical findings revealed higher frequencies of symptoms in the CF group, although not all members presented statistical significance. The frequencies of alleles related to risk were higher in the CF group for GSTM1, GSTT1, CYP2E1 7632T > A, but lower for NQO1 and CYP2E1 1053C > T genotypes. Moreover, an association was found between GSTM1 null and alterations related to BP, but we did not observe any effects of other polymorphisms. Variations in benzene metabolizing genes may modify benzene toxicity and should be taken into consideration during risk assessment evaluations.
Managing Groundwater Radioactive Contamination at the Daiichi Nuclear Plant
Authors: Marui Atsunao , Gallardo Adrian
Published: July 2015

The Great East Japan Earthquake and tsunami of March 2011 severely damaged three reactors at the Fukushima Daiichi nuclear power station, leading to a major release of radiation into the environment. Groundwater flow through these crippled reactors continues to be one of the main causes of contamination and associated transport of radionuclides into the Pacific Ocean. In this context, a number of strategies are being implemented to manage radioactive pollution of the water resources at the nuclear plant site. Along with water treatment and purification, it is critical to restrict the groundwater flow to and from the reactors. Thus, the devised strategies combine walls containment, bores abstraction, infiltration control, and the use of tanks for the temporary storage of contaminated waters. While some of these techniques have been previously applied in other environments, they have never been tested at such a large scale. Therefore, their effectiveness remains to be seen. The present manuscript presents an overview of the methods being currently implemented to manage groundwater contamination and to mitigate the impact of hydrological pathways in the dispersion of radionuclides at Fukushima.
Defining Neighbourhoods as a Measure of Exposure to the Food Environment

Published: July 2015

Neighbourhoods are frequently used as a measure for individuals’ exposure to the food environment. However, the definitions of neighbourhoods fluctuate and have not been applied consistently in previous studies. Neighbourhoods defined from a single fixed location fail to capture people’s complete exposure in multiple locations, but measuring behaviour using traditional methods can be challenging. This study compares the traditional methods of measuring exposure to the food environment to methods that use data from GPS tracking. For each of the 187 participants, 11 different neighbourhoods were created in which the exposure to supermarkets and fast food outlets were measured. ANOVA, Tukey’s Honestly Significant Difference (HSD) test and t-tests were performed to compare the neighbourhoods. Significant differences were found between area sizes and the exposure to supermarkets and fast food outlets for different neighbourhood types. Second, significant differences in exposure to food outlets were found between the urban and rural neighbourhoods. Neighbourhoods are clearly a diffused and blurred concept that varies in meaning depending on each person’s perception and the conducted study. Complexity and heterogeneity of human mobility no longer appear to correspond to the use of residential neighbourhoods but rather emphasise the need for methods, concepts and measures of individual activity and exposure.
NOS1AP O-GlcNAc Modification Involved in Neuron Apoptosis Induced by Excitotoxicity

Published: July 2015

O-Linked N-acetylglucosamine, or O-GlcNAc, is a dynamic post-translational modification that cycles on and off serine and threonine residues of nucleocytoplasmic and mitochondrial proteins. In addition to cancer and inflammation diseases, O-GlcNAc modification appears to play a critical role during cell apoptosis and stress response, although the precise mechanisms are still not very clear. Here we found that nitric oxide synthase adaptor (NOS1AP), which plays an important part in glutamate-induced neuronal apoptosis, carries the modification of O-GlcNAc. Mass spectrometry analysis identified Ser47, Ser183, Ser204, Ser269, Ser271 as O-GlcNAc sites. Higher O-GlcNAc of NOS1AP was detected during glutamate-induced neuronal apoptosis. Furthermore, with O-GlcNAc sites of NOS1AP mutated, the interaction of NOS1AP and neuronal nitric oxide syntheses (nNOS) decreases. Finally, during glutamate-induced neuronal apoptosis, decreasing the O-GlcNAc modification of NOS1AP results in more severe neuronal apoptosis. All these results suggest that O-GlcNAc modification of NOS1AP exerts protective effects during glutamate-induced neuronal apoptosis.
Porous Materials for Hydrolytic Dehydrogenation of Ammonia Borane

Published: July 2015

Hydrogen storage is still one of the most significant issues hindering the development of a “hydrogen energy economy”. Ammonia borane is notable for its high hydrogen densities. For the material, one of the main challenges is to release efficiently the maximum amount of the stored hydrogen. Hydrolysis reaction is a promising process by which hydrogen can be easily generated from this compound. High purity hydrogen from this compound can be evolved in the presence of solid acid or metal based catalyst. The reaction performance depends on the morphology and/or structure of these materials. In this review, we survey the research on nanostructured materials, especially porous materials for hydrogen generation from hydrolysis of ammonia borane.

Published: July 2015

In order to compare the coordination properties of 1,4,7-triazacyclononane (tacn) derivatives bearing varying numbers of phosphinic/carboxylic acid pendant groups towards 68Ga, 1,4,7-triazacyclononane-7-acetic-1,4-bis(methylenephosphinic) acid (NOPA) and 1,4,7- triazacyclononane-4,7-diacetic-1-[methylene(2-carboxyethyl)phosphinic] acid (NO2AP) were synthesized using Mannich reactions with trivalent or pentavalent forms of H-phosphinic acids as phosphorus components. Stepwise protonation constants logK1–3 12.06, 3.90 and 1.95, and stability constants with GaIII and CuII, logKGaL 24.01 and logKCuL 16.66, were potentiometrically determined for NOPA. Both ligands were labelled with 68Ga and compared with NOTA (tacn-N,N′,N″-triacetic acid) and NOPO, a TRAP-type [tacn-N,N′,N″- tris(methylenephosphinic acid)] chelator. At pH 3, NOPO and NOPA showed higher labelling efficiency (binding with lower ligand excess) at both room temperature and 95 °C, compared to NO2AP and NOTA. Labelling efficiency at pH = 0–3 correlated with a number of phosphinic acid pendants: NOPO >> NOPA > NO2AP >> NOTA; however, it was more apparent at 95 °C than at room temperature. By contrast, NOTA was found to be labelled more efficiently at pH > 4 compared to the ligands with phosphinic acids. Overall, replacement of a single phosphinate donor with a carboxylate does not challenge 68Ga labelling of TRAP-type chelators. However, the presence of carboxylates facilitates labelling at neutral or weakly acidic pH.
