The use of modern techniques for application in the field of reproduction grows more and more in veterinary medicine and therefore studies are needed to evaluate the efficiency of these techniques. Due to the cortical location of the follicles within the ovary, Slicing is the most adequate technique to obtain canine oocytes, which presents better results in relation to the amount of oocytes collected when compared to other techniques. The aim of this study was to verify the quality of oocytes collected from ovaries of bitches and cats with different ages submitted to the Salpingo Ovary Hysterectomy (OSH) procedure at the Veterinary Hospital of the Federal University of Campina Grande. The oocytes were classified according to their quality in relation to the morphology of the cumulus oophorus complex. The age and estrus stage in which bitches and cats were at the time of collection did not influence the quality and quantity of oocytes collected.

Aims
Triple valve surgery (TVS) may still be considered a challenge in cardiac surgery, and is still associated with a not negligible mortality and morbidity. This study analyzed retrospectively patients’ data from RERIC (Registro Regionale degli Interventi Cardiochirurgici) registry, to evaluate early and mid-term results of TVS.

Methods
From April 2002 to December 2013, data from n = 44 211 cardiac surgical procedures were collected from six Cardiac Surgery Departments (RERIC). Two hundred and eighty patients undergoing TVS were identified, including aortic and mitral replacement with tricuspid repair in 211 patients (75.3%), aortic replacement with mitral and tricuspid repair in 64 (22.9%) and triple valve replacement in 5 (1.8%). Univariate and multivariate analyses were performed to identify predictors of overall mortality or adverse outcomes.

Results
The mean age of the patients was 67.5 ± 12.2. Overall in-hospital mortality rate was 7.9%: in-hospital mortality was 10.9% in mitral valve repair and 6.6% in mitral valve replacement, respectively. Tricuspid valve replacement was associated with the highest mortality rate (40%). Independent predictors of in-hospital mortality were serum creatinine greater than 2 mg/dl [odds ratio (OR) 4.5; P = 0.03], concomitant coronary artery bypass graft (CABG) (OR 3.8; P = 0.01) and previous cardiac surgery (OR 5.1; P = 0.04). Overall cumulative mortality rate at 1, 3 and 5 years was 14.7, 24.1 and 28.9%, respectively. Mitral valve replacement associated with tricuspid valve repair showed better survival rate (hazard ratio 0.1; P = 0.007).

Conclusion
TVS has demonstrated satisfactory results in terms of in-hospital and mid-term mortality rate. Renal failure, reoperations and concomitant CABG resulted as risk factors for mortality; moreover, we could not demonstrate a mid-term better survival rate of mitral valve repair compared with the replacement.

Los autores proponen un estudio climatológico de la altura significativa del oleaje (Hs) en la cuenca colombiana mediante el análisis de datos de altimetría tomados por los satélites Jason-1, Topex -Poseidón, ERS-2, Envisat and Geosat-2 (GFO), catalogados en la base de datos AVISO Delayed Time Corrected Sea Surface Heights entre septiembre 1992 y abril 2009.
La cartografía mensual de la altura significativa media del oleaje analizada en ventanas de 0.5° x 0.5° revela valores de altura importantes para enero y febrero, cuando los vientos alisios son más intensos, seguidos por los valores de junio y julio. Estos últimos debidos a la ocurrencia de vientos del Veranillo.
El análisis de la variabilidad interanual sobre cuatro ventanas de 1° x 1°, situadas cerca del Golfo de Urabá, Cartagena, Barranquilla y Riohacha presenta niveles de altura significativa del oleaje, que aumentan en sentido este/oeste. Exceptuando los valores del norte del golfo de Urabá con una posición geográfica más protegida. Por otra parte, no se observó aumento de la altura significativa máxima en el período 1992-2009.
La estimación de altura significativa del oleaje para diferentes probabilidades de retorno, permite constatar que para ocurrencias de 10 y 50 años, las alturas correspondientes son de 4.17 y 4.53 m. para Riohacha, 4.75 y 5.11 m. para Barranquilla, 5.23 y 5.51 mts para Cartagena y de 4.83 y 5.43 mts para el norte del golfo de Urabá.
Efectos de la descarga estacional del Canal del Dique en el mecanismo de intercambio de aguas de una bahía semicerrada y micromareal: Bahía de Cartagena, Colombia
Authors: Molares Ricardo , Mestres Marc 
Published: June 2018

Las características mareales de la Bahía de Cartagena (Colombia), su morfología y la fluctuación estacional del caudal de descarga del Canal del Dique modifican el mecanismo de intercambio de agua de la bahía con el mar abierto a través de dos entradas: Bocagrande y Bocachica. Con el fin de estudiar el proceso de intercambio de agua, tres escenarios diferentes fueron diseñados y numéricamente modelados, utilizando el Sistema de Modelación Regional del Océano (ROMS_AGRIF).
Los resultados mostraron que las fluctuaciones del caudal de descarga del Canal del Dique modifican fuertemente el régimen de corrientes de flujo y reflujo a través de las entradas de la bahía. Considerando el incremento sostenido en la descarga del río (de bajo a alto caudal de descarga) a lo largo del año y la intensidad de la corriente promedio que fluye hacia afuera de la bahía (reflujo) a través de Bocagrande, esta corriente aumentó hasta un 60 %, mientras que las corrientes dirigidas hacia la bahía (flujo) a través de Bocachica, experimentaron variaciones entre el 23 % (en el sector profundo de la entrada-canal de navegación) y 50 % (en la sección de agua someras de esta entrada).
Durante la época de alta rata de descarga del Canal del Dique, a través de la entrada de Bocagrande al noroeste de la bahía, el flujo de masas de agua es generalmente dirigida hacia afuera de la bahía. Esto es mayormente debido a la presencia de La Escollera, que se extiende entre la isla Tierrabomba y el continente, la cual actúa como una pared que previene el influjo de las aguas oceánicas densas sobre el fondo. Al mismo tiempo, el agua mezclada y menos densa en la superficie, es empujada fuera de la bahía por la corriente inducida por la descarga del Canal del Dique.
Al suroeste de la bahía (Bocachica) se identifican dos regímenes de intercambio de masas. En la sección somera, cercana al continente, el régimen es similar al detectado en Bocagrande, y también al observado en las capas superficiales (0 a 6 m) sobre el canal navegable en Bocachica. En las capas profundas de este canal, el flujo de agua se dirige hacia la bahía.

El Centro de Investigaciones Oceanográficas e Hidrográficas del Caribe (CIOH), en representación de la Dirección General Marítima (Dimar), autoridad marítima nacional, comprometida con los procesos de reglamentación y estandarización de las actividades que se realizan en la jurisdicción del puerto de Cartagena, especialmente los levantamientos de información batimétrica que se realizan en la Bahía de Cartagena, definió los datums o niveles de referencia vertical hidrográficos basándose en una metodología que combina la utilización de datos históricos, correspondientes al año 2011, de nivel de agua registrados por la estación mareográfica ubicada en el muelle del CIOH en la Bahía de Cartagena, cálculos matemáticos con los registros obtenidos y resultados de trabajos de campo, para relacionar la red geodésica nacional con los niveles verticales obtenidos. De esta forma se generó el metadato que permite referir un levantamiento hidrográfico a los niveles determinados acorde a la necesidad y/o propósito final del trabajo.
Los datums obtenidos fueron: MLWS (promedio de las bajamares de sicigia), utilizado para la referenciación de la cartografía náutica oficial colombiana; LAT (marea astronómica más baja) y MSL (nivel medio del mar). Todos los ante¬riores corresponden a datums recomendados por la Organización Hidrográfica Internacional (OHI) para la referenciación vertical de levantamientos hidrográficos, especialmente el MLWS y el LAT. Adicionalmente se calcularon los datums MHWS (promedio de las pleamares de sicigia) y HAT (marea astronómica más alta). Además de los fines de generación cartográfica, los resultados obtenidos permitirán ampliar el rango de productos, análisis y estudios que se derivan del cálculo, im¬plementación y estandarización de los niveles verticales, como es el caso de las fusiones con datos espaciales producto de levantamientos en tierra, utilización de la metodología para medición de ascensos y descensos del nivel de agua por medio de tecnología GNSS RTK; siendo ésta la de más alta precisión disponible en la actualidad en el desarrollo de levantamientos hidrográficos en el ámbito mundial, por parte de la Dimar, contar con el soporte técnico para exigir la estandarización a un mismo nivel de referencia vertical,de los levantamientos hidrográficos que realizan entidades externas generando un control eficiente que resolverá definitivamente discrepancias que se han presentado constantemente cuando se confrontan productos de distintas entidades.

Published: June 2018

Se realizó una descripción y análisis del proceso de intercambio de masas de agua en la bahía de Cartagena, para lo cual se efectuaron salidas de campo, en las cuales se tomaron diferentes mediciones de parámetros oceanográficos en las entradas de la bahía (Bocagrande y Bocachica), así como en la descarga del Canal del Dique a la bahía. Otros aportes de agua no se tuvieron en cuenta. Las mediciones se efectuaron en las dos épocas (seca y húmeda), con el fin de determinar la influencia de los extremos estacionales en la dinámica de la bahía, principalmente del Canal del Dique, que durante la época de lluvias triplicó el aporte en el volumen de agua hacia la bahía.
Durante la época seca y en el sector de Bocachica (mediciones efectuadas durante un ciclo de marea) se presentó un flujo dominante hacia la bahía, correspondiente a un volumen de 59.1567x106 m3 durante un ciclo de marea y un flujo de salida por Bocagrande correspondiente a un volumen de 76.2013x106 m3, con una disminución del 28.81 % en el volumen de agua de la bahía. En la época de lluvias y durante un ciclo de marea, el volumen de agua que ingresó a la bahía (Bocachica y Canal del Dique) fue de 89.8590x106 m3, mientras que el volumen de salida por Bocagrande fue de 78.5392x106 m3, con un incremento del 12.59 % en el volumen de agua de la bahía.
Estos resultados corroboran los obtenidos por Molares y Mestres (2013), quienes simularon la dinámica de la bahía y determinaron una variación en los regímenes de flujo de entrada y salida a la bahía dependiendo de la época del año. Se resalta la importancia de los resultados obtenidos, los cuales indican las variaciones del volumen de agua dentro de la bahía, adquiriendo importancia por el impacto socioeconómico y ecológico que puede tener en este importante sistema estuarino.

Authors: Abdul-Razzaq Khattab Saleem , F. Jebur Sarah , H. Mohammed Abbas 
Published: June 2018

This work aims at presenting detailed procedures companied by numerical examples for analyzing and designing reinforced concrete deep beams that subjected to non-central loadings based on Strut and Tie method (STM). The subjected loadings were moved from the center of the beam span towards the supports reaching the maximum non-centrality could be achieved (after which the beams became ‘not deep’ from ACI 318M-14 point of view). A total of three deep beams with three different types of loadings were taken into considerations; one concentrated force, two concentrated forces and uniformly distributed load. Every specimen had a cross section of 150 400 mm and a total length of 1000 mm. Generally, it was found that moving load from the span center towards one of the supports leads to worth notable decreases in the beam ultimate capacity. Therefore, in the case of one-concentrated force, the ultimate load capacity decreased by 30.2% when left shear span to effective depth ratio (aL/d) decreased from 1.3 to 0.65. While in the cases of two-concentrated forces or uniformly distributed loading, it was found that changing (aL/d) ratio from 1.02 to 0.37 led to decrease the deep beam ultimate capacity by 30.5%.

Six reactive powder concrete corbels were tested. Divided into two groups, each group contain three specimens, one of them without strengthening takes as control corbel specimen, two corbels in each group strengthened by inclined and horizontal near surface mounted carbon fiber reinforced polymer (NSM-CFRP) stripes, other variable was the shear span to the effective depth ratio (a/d) to study the influences of those variables on the ultimate strength carrying capacity, cracking pattern, cracking load, vertical deflection, failure modes. The results showed an important improvement in the behaviour and load capacity of strengthened reinforced RPC corbels in addition to enhancing the stiffness of corbels. For group A where a/d =0.65, the percentages of increase in load failure were about (10.3% - 15.45%) for inclined and horizontal strengthening respectively, and for group B where a/d =0.4, the percentages of increase in load failure were about (7.1% - 14.6%) for inclined and horizontal strengthening respectively.

This paper for the first time investigates the workability, compressive and tensile strength of concrete containing Fly Ash, Rice Husk Ash and Waste Glass Powder. Seventy six cube specimen (150 150 150 mm were cast with different composition of Fly Ash, Rice Husk Ash ,Waste Glass Powder and steel fibers. The cubes were tested for axial compression and tensile tests. The research also investigated the effect of curing regime on the compressive and tensile strength of concrete cube specimen. The results revealed that the addition of 15 % Rice Husk Ash and 39% Fly Ash increased the workability of 25 % as compared to the controlled concrete. The sample containing 10 % Rice Husk Ash, 10% Waste Glass Powder and 39% micro silica produced worst workability as it decreased the workability up to 5 % of controlled concrete. The results for axial compressive strength shows that the addition of 15% Rice Husk Ash (RHA) and 39% of Fly Ash (FA) in concrete leads to the improvement of compressive strength by 14%. The sample containing replacement of 10% Rice Husk Ash (RHA), 10% waste glass powder (WGP) and 39 % of micro silica (MS) in concrete leads to the improvement by 53.9 for compressive. The replacement of 10% Rice Husk Ash (RHA), 10% waste glass powder (WGP ), 39 % of micro silica (MS) 3% steel fiber in concrete leads to the improvement by 37% for compressive strength. It was observed from the results of tensile strength that the samples containing 15% Rice Husk Ash (RHA) and 39 % of Fly Ash (FA) increased the tensile strength by 24% as compared to the controlled concrete. The sample containing replacement of 10% Rice Husk Ash (RHA), 10% waste glass powder (WGP) and 39 % of micro silica (MS) in concrete leads to an increase of 20% as compared to the controlled ones. Also, the replacement of 10% Rice Husk Ash (RHA), 10% waste glass powder (WGP), 39 % of micro silica (MS) 3% steel fiber increased the tensile strength by 40 % as compared to the controlled concrete sample. Finally, it was concluded that the replacement of 10% RHA, 39% micro Silica, 10% WG in concrete was found to be superior for increasing the mechanical properties of concrete.

Authors: Zamanisabzi Hamed , King James Phillip , Dilekli Naci , Shoghli Bahareh , Abudu Shalamu 
Published: June 2018

This study illustrates the benefits of data pre-processing through supervised data-mining techniques and utilizing those processed data in an artificial neural networks (ANNs) for streamflow prediction. Two major categories of physical parameters such as snowpack data and time-dependent trend indices were utilized as predictors of streamflow values. Correlation analysis of different models indicate that, for the period of January to June, using fewer predictors led to simpler modeling with equivalent accuracy on daily prediction models. This did not hold in all periods. For monthly prediction models, accuracy was improved compared to earlier works done to predict monthly streamflow for the same case of Elephant Butte Reservoir (EB), NM. Overall, superior prediction performance was achieved by utilizing data-mining techniques for pre-processing historical data, extracting the most effective predictors, correlation analysis, extracting and utilizing combined climate variability indices, physical indices, and employing several developed ANNs for different prediction periods of the year.

Published: June 2018

Daily increase in the amounts of soil and wastes produced by excavation and demolishing of the old buildings in the urban worn out textures has caused great problems in large cities. The environmental issues due to the irrelevant and non-technical disposal of waste materials have attracted attention of researchers with the aim of recycling and use of these materials in the civil and construction activities. Old buildings constitute a significant portion of Sharestan Razavi Blvd in Mashhad which after demolishing of these buildings the area in this section is covered by the backfill materials and those remained from the demolishing of the buildings. In this research, maximizing use of the available materials and minimizing the transportation work as an execution order have been under focus of attention. Also through performing various tests, the possibility of recycling, stabilizing and implementing these materials at underlying layers of Sharestan Razavi Blvd has been evaluated and the results are presented.

Published: June 2018

<p>The term “phthalates” refers to a group of esters of benzene-1,2-dicarboxylic acid, widely used as plasticizers therefore ubiquitous in food and in the environment. Several phthalates have been cataloged as endocrine disruptors and that is why there is a strong demand for their reliable determination, especially in food matrices. In the present work, gas chromatography - tandem mass spectrometry (GC-MS/MS) procedure is proposed for the determination of six priority phthalates (dimethyl phthalate DMP, diethyl phthalate DEP, di(n-butyl) phthalate DBP, benzyl butyl phthalate BBP, di(2-ethylhexyl) phthalate DEHP, di(n-octyl) phthalate DnOP) and di(2-ethylhexyl) adipate DEHA, in maize tortillas and flour. Fresh tortilla sample was homogenized with acetonitrile/water (1:1) and after salting out (NaCl), hexane extract was obtained and dried by addition of Na<sub>2</sub>SO<sub>4</sub> anhydride. Finally, solvent was evaporated and the residue was reconstituted in isooctane for the injection to GC-MS/MS system; a model SCION GC-TQMS from Bruker Daltonics was used for the analysis. Quantification was carried out by multiple reaction monitoring (MRM) with the following time segments and m/z values of the precursor/product ion transitions: 0-7.90 min, 163/133 DMP; 7.47-8.53min, 149/121 DEP; 8.53-9.93 min, 149/121 DBP; 9.93-12.39 min, 149/93 BBP; 11.40-12.44 min, 129/111 DEHA; 12.20-13.22 min, 149/121 DEHP; 13.13-14.20 min, 149/121 DnOP. The evaluated method detection limits for seven compounds were in the range 0.11-1.84 µg kg<sup>-1</sup> (tortilla dry mass). The results obtained for fifteen tortilla samples purchased in Guanajuato state were as follows: 71.6-420 µg kg<sup>-1</sup> DEHP &gt; not detected (nd)-274 µg kg<sup>-1</sup> DBP &gt; nd-197 µg kg<sup>-1</sup> DEHA &gt; nd-73.2 µg kg<sup>-1</sup> DEP &gt; nd-10.6 µg kg<sup>-1</sup> DnOP. It was observed that prolonged storage and elevated temperature favored the accumulation of phthalates in tortillas.</p>
