El presente estudio tuvo como objetivo comparar el peso corporal, así como índices cardiacos, hematocrito y hemoglobina como indicadores de trabajo cardiaco de dos líneas de pavos de engorde criados a nivel del mar. Se trabajó con 35 pavos de la línea BUT y 35 de la línea Hybrid. El peso corporal (PC) se registró desde la 4ª a la 14ª semana de edad en que fueron beneficiados. En ese momento, se tomó una muestra de sangre para determinar el hematocrito y la hemoglobina; además, se extrajeron los corazones y se determinaron las relaciones de peso ventrículo derecho/ventrículo total (VD/VT), peso ventrículo izquierdo/ventrículo total (VI/VT), peso ventrículo izquierdo + septo/ ventrículo total (VI+S/VT), VI/PC, VD/PC, VI+S/PC y VT/PC. El peso corporal y la hemoglobina en pavos BUT fueron superiores (p<0.05), mientras que el hematocrito fue mayor (p<0.05) en pavos de l...

The Qochoq river originates in the aquarium divortium, from the Amparaes pass at 5 650 masl, and in the snowmelt of the Ccolque Cruz, which are part of the eastern mountain range in the Calca province, Cusco; it has a runoff area of ​​162.85 km2 and a length of 20.81 km, flowing into the city of Calca in the Vilcanota river at 2 929 m of altitude. Throughout its journey it receives tributaries and due to the various economic activities such as livestock in the upper part, agricultural in the intermediate and lower zone, as well as the discharge of wastewater, solid waste and others, it loses its quality for various uses. For the determination of the water quality, the biotic indices and pollution indices were used, applying the methodology proposed by Tuffery & Verneaux using systematic lists based on macroinvertebrates or bioindicators for the determination of the biotic indices...

Two of the main indices used when doing a psychometric analysis of a performance test are the index of difficulty and the index of discrimination. These indices become indicators of the quality of a test as long as they are within acceptable ranges. This has two consequences, first the determination of the formula for the calculation of the indices, and secondly, the interpretation of them according to certain standards. This work shows the way how these indices are determined and related, as well as the way in which the discrimination rule influences the valuation of the test. Recommendations are also proposed for the use of both indices based on the analysis performed.

Two new reactivity indices were developed within the conceptual framework of the Density Functional Theory. These new descriptors, called electrophilic susceptibility index and nucleophilic susceptibility index, were tested to reproduce the chemical reactivity trends of series of halogen-substituted quinones and 5-substituted indoles, respectively. The above mentioned molecular system were computationally treated by using the B3LYP/6-31G(d) level of theory. For these systems, the proposed descriptors showed to be more appropriate than other descriptors currently known such as the electrodonating power, the electroaccepting power and the popular electrophilicity index.

En este estudio se evaluó el efecto de tres tipos de empadre y dos tipos de alimentación sobre parámetros reproductivos. Se utilizaron 210 cuyes hembras y 30 machos reproductores en un diseño de bloques completos al azar con arreglo factorial de tres tipos de empadre (posparto, posdestete y posdescanso) x dos tipos de alimentación (forraje verde, forraje verde más suplemento). El estudio comprendió la evaluación de las reproductoras durante el segundo y tercer parto. Se encontró efecto del tipo de empadre sobre las variables peso al nacimiento, número de partos por año y uso eficiente del celo (p<0.05). También hubo efecto del tipo de alimentación sobre la variable peso al nacimiento (p<0.05). La interacción tipo de alimento por tipo de empadre fue significativa,indicando que la suplementación tiende a mejorar la tasa de fertilidad, el tamaño de camada y el índice ...

Globalization has intensified competition in many markets. To remain competitive, the companies look for satisfying the needs of customers by meeting market requirements. In this context, Process Capability Indices (PCI) play a crucial role in assessing the quality of processes. In the case of non-normal data there are two general approaches based on transformations (Box-Cox and Johnson Transformation) and Percentiles (Pearson’s and Burr’s Distribution Systems). However, previous studies on the comparison of these methods show different conclusions, and thus arises the need to clarify the differences between these methods to implement a proper estimation of these indices. In this paper, a simulation study is made in order to compare the above methods and to propose an appropriate methodology for estimating the PCI in non-normal data. Furthermore, it is concluded that the best method ...

            The aim of this study was to characterize the morphology of the creole goat of the Volcanes de Colima physiographic sub-province, Mexico. Seventeen body measurements were taken from 371 goats older than two years and four racial indices and 17 functional indices were calculated. Data were analysed using Pearson correlation, principal component, and hierarchical cluster analysis. The rump angle, chest width and all measurements of the ears and udder showed the greatest variability. Also, the goats showed great morpho-structural harmony. Racial indices showed that goats are dolichocephalic, ellipometric, and have a convex rump, while functional indices indicated dual-purpose zootechnical aptitude. Four principal components explained 84.5% of the variation of body measurements. Rump angle, hearth girth, body length and ear l...

An enterprise aim is to search the increasing of an enterprise's value through maximizing utilities and heritage with the purpose of minimizing risk levels and thus to obtain a suitable solvency in order to face short-time engagements. The real challenge to find the enterprise's value and to interpret it, through Financial Indicators that, even though they are considered to be clear and easy reasons to be worked out, might decrease their effectiveness as instruments for wealth measuring and the Added Economic Value(AEV) which is a tool which tries to counteract these indicators limitations by valueing and assessing any management perfomance through value creation.
