Abstract: key properties of seed of mexican lime (citrus aurantifolia swingle) were studied for potential uses by the food industry. characteristics considered included physical properties, composition, toxicity to rodents (average lethal dose and chronic toxicity), as well as germicidal activity (inhibition rings and germicidal effectiveness). the seed contained 21% protein, 39% vegetable oil and 29% fiber, particularly lignin. the seed could potentially be used as a basic component for nutritional supplements or functional food products. the toxicity was nil, and thus seed derivatives were safe for human consumption. some germicidal effectiveness was found against candida albicans, 85.77% (starting population = 0.304*108 ufc/ml), and against escherichia coli, 91.447% (starting population = 190*108 ufc/ml), suggesting seed extracts could be used as an ingredient in germicidal products.

Abstract: Se obtuvieron propiedades clave de la semilla de limón mexicano (Citrus aurantifolia swingle) para su posible aprovechamiento en la industria de alimentos. Se consideraron propiedades físicas, composición, toxicidad en roedores (prueba de dosis letal media y toxicidad crónica) y actividad germicida (prueba de halos de inhibición y efectividad germicida). La semilla contiene 21% de proteínas, 39% de aceite vegetal y 29% de fibra, especialmente lignina en cantidad considerable, lo que hace viable su uso como materia prima para nutracéuticos o alimentos funcionales. La toxicidad de la semilla resultó nula por lo que es apta para el consumo humano. Se encontró cierta efectividad germicida para Candida albicans 85.77% (población Inicial = 0.304*10(8) UFC/ml) y para Escherichia coli 91.447% (población Inicial = 190*10(8) UFC/ml), por lo que puede ser usada como ingrediente en germicidas.

Abstract: Se presenta un análisis comparativo de modelos de flujo desarrollados para los sólidos de un sistema de lechos fuente en multietapa (multistage spouted bed) dise ado por Arriola (1997). Se seleccionaron modelos de distribución del tiempo de residencia de los sólidos adecuados para la aplicación comercial del sistema en el tratamiento de granos y semillas. La determinación experimental de la función de distribución del tiempo de residencia se llevó acabo mediante la técnica estímulo-respuesta utilizando partículas coloreadas. Se compararon cuatro modelos: tres de compartimentos y el de tanques-en-serie. La comparación de esos modelos mostró que los de compartimentos son los más apropiados para aplicaciones comerciales. El análisis estadístico permite afirmar que el modelo más recomendable, debido a su simplicidad, es el modelo de compartimentos propuesto por Arriola A comparative analysis of flow models developed for the solids in a multistage spouted bed system designed by Arriola (1997), is presented.

RCOE , 2007, DOI: 10.4321/S1138-123X2007000100003
Abstract: background: the relationship between occlusal discrepancies and tmj disorders does not always hold true. nonetheless, occlusal analysis is a requisite to achieve a correct diagnosis in the dysfunctional patient. many studies show that occlusal discrepancies can be a very important etiological factor. material and methods: various literature reviews describe the main occlusal types and the possibility of structural and functional relationships with tmj derangements. results: the relationship between each kind of malocclusion and a specific tmj disorder is due to different condyle positions in the glenoid fossa. it may be appropriate to introduce the term tooth-condyle unit because the stomatognathic system has a specific bone block or mandible, which encompass teeth and condyles. the various occlusal schemes can be considered dynamic which influences the joint. conclusion: the involvement of occlusion in the etiology of tmj disorder is conditioned by the presence of other factors. however, physiologic occlusion must be re-established for correct joint function. this implies that the specific biomechanics of each patient and it's correlation with biological parameters must be known in order to provide joint homeostasis.

García Contreras, O.J.;Mu?oz Bravo, Jorge E.;Fajardo, F.;
Revista Brasileira de Ensino de Física , 2008, DOI: 10.1590/S1806-11172008000400005
Abstract: the phenomenon of temperature distribution in a rotating gas flow is known as the ranque-hilsch effect. the ranque-hilsch tube (r-h ) is a system that in absence of movable parts separates an air flow in two portions, cold and hot ones. in this work a r-h tube is constructed using low cost pieces. we showed that effect is dependent of some of its parameters like the: tube length, the exit diameter of cold air and the diameter of a cylindrical valve in the temperature gradient generated at its ends. as result a configuration of the tube is obtained that optimizes the temperature difference of the flow. the r-h tube is constructed with materials of low cost and easy to obtain, which facilitates its assembly in order to illustrate some phenomena in fluid mechanics and thermodynamics labs in engineering and physics courses.

Abstract: Energy development plans involving the use of solar energy are very beneficial from an environmental perspective. Its impacts are specific to geographic location; taking advantage of the solar energy potential basically depends on reliable estimates of the climatological amount of solar radiation received at the surface, which is a complex function of meteorological and environmental factors. Obtaining solar radiation data is essential for local development, to characterize them, there are several cutting-edge methods and technologies. One of them is the use of satellite images with high resolution. The aim of this paper is to assess the climatological aspects of incoming solar radiation in clear sky conditions in the State of Jalisco, Mexico and Guadalajara Metropolitan Zone. The results are intended to stimulate the use of solar radiation as an alternative energy source in an area where heavily relying on fossil fuel combustion.
EL FOMENTO DE LA "ECONOMIA SOCIAL" EN LA LEGISLACIóN ESPA OLA / PROMOTING THE "SOCIAL ECONOMY" IN SPANISH LEGISLATION

Abstract: La “economía social” como concepto identificativo de una forma de hacer empresa, caracterizada por sus fines y ciertas pautas de comportamiento comunes, ha tenido reconocimiento en la legislación espa ola desde los a os 90 y especialmente en el último a o con la aprobación de la Ley 5/2011 de Economía Social. Los objetivos principales de esta Ley son dar reconocimiento legal a la economía social y promover su fomento. Pero la economía social, como identificación de una realidad económica viene siendo objeto de fomento desde mucho antes, desde la creación en 1990 del Instituto Nacional de Fomento de la Economía Social. Hoy en día, el fomento de la economía social es una competencia asumida por todas las Comunidades Autónomas. Se subvencionan normalmente los gastos derivados de actividades de promoción de la economía social y los gastos generales de funcionamiento de sus entidades representativas. Pero el concepto de economía social utilizado identifica, con alguna excepción (mutualidades y empresas de inserción), exclusivamente a las cooperativas y sociedades laborales. La razón está en que dentro de cada administración pública el fomento de la economía social suele ser competencia de la administración competente en materia de empleo. Con la nueva ley, el fomento de la economía social debería alcanzar a todas las demás familias y para ello sería aconsejable que su fomento se atribuyese a un organismo interministerial / The “social economy” as a concept identifies a way of doing business, characterized by its purposes and certain patterns of common behavior, it has been recognized in Spanish legislation since the 90//////s and especially in the last year with the approval of Social Economy Law 5 / 2011. The main objectives of this Act are giving legal recognition to the social economy and promote its development. But the social economy, as identification of an economic reality has been under development long before, since the creation in 1990 of the National Institute for the Promotion of Social Economy. Nowadays, the promotion of social economy is a responsibility assumed by the Autonomous Communities. It usually subsidize the costs of activities to promote the social economy and general operating expenses of their representative entities. But the concept of social economy usually identifies, with some exceptions only to cooperatives and worker-owned companies. The reason is that within each public administration to promote the social economy is generally the responsibility of the competent authority in employment. With the new law, the promotion of soci

Abstract: Congenital dilatation of the bile duct and its incidence is a rare condition reported in one in 100 000 to 150 000 newborns. Current concern about the evolution of this process is that a cholangiocarcinoma might appear. The case of a female teenager of urban origin, who attended her health area polyclinic, because of a moderate 5 months pain in her high epigastrium and in her upper right abdomen is presented. The pain appeared always after eating accompanied by vomiting and it was self-relieved. An abdominal ultrasound indicated by the patient’s family doctor showed a liver cyst. It was decided to perform an abdominal computed tomography. Through this test a cyst at the pancreatic head was found. The patient was admitted in the emergency room of the ‘’Gustavo Aldereguía Lima’’ Hospital of Cienfuegos, where she was evaluated by the physicians in the Surgery Department. It was decided to treat her surgically. Anatomopathologic results showed chronic cholecystitis, choledochal cyst and nonspecific chronic inflammation. La dilatación congénita de las vías biliares y su incidencia es rara, se presenta un caso cada 100 000 a 150 000 nacimientos. La preocupación actual respecto a la evolución de este proceso, es que origine un colangiocarcinoma. Se presenta el caso de una adolescente de procedencia urbana, que acudió a cuerpo de guardia de su área de salud, refiriendo que desde hacía aproximadamente 5 meses presentaba dolor moderado en ¨la boca¨ del estómago y en la región superior derecha del abdomen que aparecía siempre después de ingerir alimentos, se aliviaba por sí solo y se acompa aba de vómitos. Su médico de familia indicó ultrasonido abdominal, donde se observó un quiste en el hígado. Fue trasladada al Cuerpo de Guardia del Hospital General Universitario Dr. Gustavo Aldereguía Lima, de Cienfuegos, donde fue valorada por el Servicio de Cirugía. Se decidió la realización de tomografía axial computarizada de abdomen en la que se observó un quiste a nivel de la cabeza del páncreas. Se aplicó tratamiento quirúrgico. Los resultados anatomopatológicos mostraron colecistitis crónica, quiste de colédoco e inflamación crónica inespecífica.
