Characterization of Physical and Motor Disability at the Technical University of Manabí
The work aims to determine the characterization of physical and motor disability and its relation to resilience in the students of the Technical University of Manabí. The paper shows an analysis of physical motor disability in students and its impact on the level of resilience. The resilience analysis was addressed terms physical and mental state of the people, as well as the process of adapting to the problems and adversities of life. The results were shown in tables and graph on the analysis of the degree of physical-motor disability of the students as well as the application of the SV-RES test prepared by the researchers Saavedra & Villalta, 2008. Based on the evaluation of 12 dimensions, which they allow to verify the situation according to three scales: high, average and low. Finally, the conclusions were offered where the objective stated in the investigation was verified

Hydrogymnastics training program on physical fitness in elderly women
Se evaluó un programa de entrenamiento de hidrogimnasia sobre las capacidades físicas en 26 adultas mayores (grupo experimental n=16, grupo control n=10), determinadas mediante el protocolo senior fitness test, la hidrogimnasia fue 5 veces por semana por 12 semanas, con ejercicios aeróbicos del 50%-60% de la FCmáx. Se utilizó ANOVA 2x2, indicando interacción significativa (p=0.052) entre grupos y mediciones en la prueba de resistencia a la fuerza en extremidades inferiores, la prueba de agilidad de 2.4 metros tuvo interacción significativa (p≤0.01) entre grupos y mediciones, las pruebas de capacidad aeróbica step test de 2 minutos (p=0.02) y caminar 6 minutos indicaron interacción significativa entre grupos y mediciones (p=0.50); Se infiere que la hidrogimnasia en las adultas mayores participantes es eficaz en la mejora de las capacidades físicas principalmente aeróbicas, de resistencia a la fuerza y agilidad de miembros inferioresThe aim of this study was to evaluate the effect of a hydrogymnastics training program on physical fitness in 26 elderly women (experimental group n=16, control group n=10). The physical fitness was determined by the senior fitness test protocol, the hydrogymnastics consisted in aerobic exercise at 50%-60% of maximum heart rate, 5 times a week in a period of 12 weeks. ANOVA 2x2 as statistical test was used, indicating statistically significant interaction (p=0.052) between groups and measurements on test strength endurance in the legs by squatting on chair in 30 s, agility test 2.4 meters was significant interaction (p≤0.01) between groups and measures, testing aerobic capacity test step 2 minutes (p=0.02) and six minutes walk indicated significant interaction between groups and measurements (p=0.50), the results shown that hydrogymnastics in the elderly women participants was effective improving endurance, strength and agility mainly in leg
Conception rate of artificially inseminated holstein cows affected by cloudy vaginal mucus, under intense heat conditions.
The objective of this work was to obtain prevalence estimates of cloudy vaginal mucus in artificially inseminated Holstein cows raised under intense heat, in order to assess the effect of meteorological conditions on its occurrence during estrus and to determine its effect on conception rate. In a first study, an association was established between the occurrence of cloudy vaginal mucus during estrus and the conception rate of inseminated cows (18,620 services), raised under intense heat (mean annual temperature of 22°C), at highly technified farms, in the arid region of northern Mexico. In a second study, data from these large dairy operations were used to assess the effect of meteorological conditions throughout the year on the occurrence of cloudy vaginal mucus during artificial insemination (76,899 estruses). The overall rate of estruses with cloudy vaginal mucus was 21.4% (16,470/76,899; 95% confidence interval = 21.1?21.7%). The conception rate of cows with clean vaginal mucus was higher than that of cows with abnormal mucus (30.6 vs. 22%). Prevalence of estruses with cloudy vaginal mucus was strongly dependent on high ambient temperature and markedly higher in May and June. Acceptable conception rates in high milk-yielding Holstein cows can only be obtained with cows showing clear and translucid mucus at artificial insemination.Título em português: Taxa de concepção de vacas Holandesas inseminadas artificialmente e afetadas por muco vaginal turvo, sob condições de intenso calor
Sperm Hyperactivation and Capacitation Induced By Light Stimuli in Cryopreserved Semen
In mammals, such as rabbits, there are some factors involved in possible fertilization, from complex changes in the membrane of the sperm to obstruction or non-existent of vas deferens, which creates problems in the number and quality of sperm. In this work, we report the effects of rabbit sperm motility and capacitation of cryopreserved semen samples under light stimuli. The sperm velocities were correlated with the percentage of capacitated and non-capacitated sperm seen with a fluorescent dye. Consequently, we analyzed the specific correlations between irradiation times, supplied energy, and fertility parameters.

Multiobjective evolutionary algorithms for multivariable PI controller design
A multiobjective optimisation engineering design (MOED) methodology for PI controller tuning in multivariable
processes is presented. The MOED procedure is a natural approach for facing multiobjective
problems where several requirements and specifications need to be fulfilled. An algorithm based on
the differential evolution technique and spherical pruning is used for this purpose. To evaluate the methodology,
a multivariable control benchmark is used. The obtained results validate the MOED procedure as
a practical and useful technique for parametric controller tuning in multivariable processes.This work was partially supported by the FPI-2010/19 grant and the project PAID-06-11 from the Universitat Politecnica de Valencia and the projects DPI2008-02133, TIN2011-28082 and ENE2011-25900 from the Spanish Ministry of Science and Innovation.Reynoso Meza, G.; Sanchís Saez, J.; Blasco Ferragud, FX.; Herrero Durá, JM.

Efecto antiproliferativo renal del enalaprilato
Introducción: El enalapril es conocido por su efecto antiproliferativo, al inhibir la Enzima de Conversión de la Angiotensina I (IECA). Revierte efectos renales de la angiotensina II entre ellos la hiperfiltración glomerular pudiendo prevenir la esclerosis. Objetivo: Analizar efecto antiproliferativo del enalaprilato en modelo renal de esclerosis en ratas wistar. Material y Métodos: 20 ratas wistar fueron divididas en 4 grupos de 5. Grupo1: tratado con enalaprilato luego de nefrectomía. Grupo 2: enalaprilato previo a la nefrectomía. Grupo 3: nefrectomía sin tratamiento. Grupo 4: enalaprilato sin nefrectomía. Dosis fue de 60 mg/Kg/día por cánula orogástrica por 1 mes. Ratas fueron sacrificadas tomándose muestras histológicas de los riñones. Fueron evaluados tamaño y peso del riñón y estadificación por grado de la lesión glomerular. Los datos se muestran en promedio y DE, y por frecuencia y porcentaje. Resultados: 87% de las ratas sobrevivieron a la nefrectomía. El promedio general del tamaño renal fue de 20x10 mm y el peso renal del G1: 1,6 ±0. 1g; G2: 1,7±0,5g; G3:2,0±0,2g y G4:1,7±0,1g. El grado máximo de glomeruloesclerosis fue grado 1(expansión mensagial/ engrosamiento de la membrana basal y/o irregularidades de las luces de los capilares); el G1 presentó 50% de afectación, G2 presentó 25 %, G3 mostró 60% y G4 sin afectación glomerular. Conclusión: El enalaprilato previene el grado de glomeruloesclerosis en el grupo G2 demostrando que administrado antes de la nefrectomía la evolución de la esclerosis disminuye en relación al G1 y G3.Con esto podemos probar el efecto antiproliferativo del IECA
Exportation of MDR TB to europe from setting with actively transmitted persistent strains in peru
We performed a cross-border molecular epidemiology analysis of multidrug-resistant tuberculosis in Peru, Spain, and Italy. This analysis revealed frequent transmission in Peru and exportation of a strain that recreated similar levels of transmission in Europe during 2007–2017. Transnational efforts are needed to control transmission of multidrug-resistant tuberculosis globally
