Abstract: Con el objetivo de conocer el comportamiento de las zoonosis y enfermedades transmitidas por alimentos (ETA) en el sector humano y animal, así como la influencia entre ambos, fue analizado el municipio Boyeros de Ciudad de La Habana entre el 1995 – 2003 para las zoonosis y el 1998 – 2003 para las ETA. Los datos fueron tomados del Instituto de Medicina Veterinaria y del Centro de Higiene y Epidemiología Municipales, y se tuvieron en cuenta en el sector humano aspectos como: zoonosis generales presentadas, número de confirmados por a o y área de salud, relación de los casos afectados con el riesgo ocupacional, y para las ETA número de brotes, total de afectados y principales agentes productores de las enfermedades, entre otros. Para las zoonosis en animales se estudió la especie, total de afectados y número de focos por a o y área de salud. Para procesar los datos se ustilizaron tablas de distribución de frecuencia, y cálculo de las tasas de fallecidos, entre otros. La Leptospirosis resultó ser la zoonosis más frecuente para hombres y animales, estando asociada fundamentalmente a grupos sin riesgos laborales. Los principales agentes productores de ETA fueron Staphylococcus aureus, Salmonella dublin y Eshericha colli, asociados fundamentalmente a los factores de riesgo: manipulación de los alimentos y tiempo de conservación – temperatura, entre otros. Los resultados obtenidos sugieren un bajo nivel de información y la necesidad de incrementar los niveles de gestión de estas enfermedades tanto para la salud animal como la salud pública. The present paper work was carried out at Boyeros municipality in Habana City. It was characterized, and one data base were made, about diseases transmitted by food and zoonotic desease. The relative incidence of the zoonotic deseases in the period ( 1995-2003) was determined, being Leptospirosis the most frequent in animals and human beings as well, the behaviour of the deseases transmitted by food (ETA) were valued during the period 1998 to 2003, finding a total of 16 bursts with 932 people affected. The principal agents isolated were Staphilococcus aureus, Samonella dublin, Escherichia coli, Clostridium perfringens, Salmonella enteritides and chemicals, being the most frequent risk factors detected the wrong manipulation of food, the weather and the temperature in the conservation of it.
Modeling molecular weight distribution, vinyl content and branching in the reactive extrusion of high density polyethylene
Asteasuain,M.; Pérez,M.V.; Sarmoria,C.; Brandolin,A.;
Latin American applied research , 2003,
Abstract: we study reactive modification of high density polyethylene by organic peroxides. we improve a previous model capable of describing average molecular weights and vinyl content to incorporate the calculation of long-chain branching and complete molecular weight distributions. we calculate average molecular weights and long-chain branching indexes for molecules with a given number of vinyls, by applying a double moment technique over those variables. no moment technique was applied to the vinyl content so the model has the capability of calculating those average quantities for every vinyl content. to calculate molecular weight distribution we apply probability generating function definitions with respect to the molecular size, to the mass balances of radical and polymer species of a given number of vinyls. we use two distinct definitions of probability generating functions, each one directly applicable either to the number or weight distributions. these probability generating functions are numerically inverted to obtain the corresponding calculated molecular weight distribution. results give a deeper insight into the evolution of vinyl groups and branching points formation. mwd and vinyl content predictions are compared with qualitative experimental data showing the model capabilities.

Abstract: El Consejo de Europa, elabora (1997) el “Convenio de Lisboa”, primer paso en el proceso de convergencia Europa en materia de Educación Superior. En la “Declaración de la Sorbona”, (1998), se insiste en la creación de un Espacio Europeo de Educación Superior en el que converjan los diversos sistemas nacionales de ense anza superior europeos: recogiendo este espíritu se elaboran y refrendan las declaraciones Bolonia” (Junio de 1999) y Praga (Mayo 2001), que “establecen de forma explicita una filosofía, un modelo de Universidad, aceptado por todos los países miembros de la unión, en el que la educación superior es considerada bien público y en el que el aprendizaje se ha de plantear a lo largo de toda la vida y la ense anza ha de estar centrada en el trabajo propio del estudiante” Los cambios sugeridos afectan a titulaciones, contenidos curriculares y formas de ense anza y suponen un cambio global de paradigma universitario, donde el papel de profesores y estudiantes cambia notablemente. Con este trabajo pretendemos promover la reflexión sobre las nuevas formas de ense anza-aprendizaje que en 2010 tendrán plena vigencia en Europa.

Abstract: background: in january 2005 the government of navarre approved the "care program for persons with severe mental disorder" (pa-tmg). this article is intended to ascertain the opinion of experts regarding the pa-tmg. to identify the elements of agreement in the evaluation of positive aspects and aspects that can be improved. to make recommendations on the basis of their opinions. methods: a delphi study was designed with 34 experts in health or social care of mentally ill persons. by means of repeated questionnaires, ideas that achieved a consensus of ?90% were identified and a level of priority was assigned. the percentages of agreement and descriptive statistics of priority were presented, and the recommendations of analysis of the areas of consensus were drawn up. results: out of the 34 participating experts, 25 (71.4%) completed the study: 1 sociologist, 5 social workers, 3 psychiatrists, 5 psychologists, one representative of the families, 3 occupational therapists, 1 technician in social integration and 6 family doctors. sixty-four percent evaluated the plan positively, and 72% were of the opinion that it was drawn up without sufficient professional participation. all thought that it could be improved by widening the participation of experts. conclusions: the principal ideas on which there was consensus were: socio-health care must be guaranteed by the public administration; good systems of information and evaluation must be established; the plan must have its own budget; professional follow-up of the patient by the different mechanisms must be guaranteed; a lot of the decision making must be decentralised; access to social benefits for these patients must be universalised.

Abstract: clean wool colour (cwc) is an important wool price determinant and has been related to suint characteristics, i.e. sudoriparous and sebaceous gland secretions, such as suint percentage and suint k content. in this work heritability, phenotypic and genetic correlations among wool colour and skin traits were examined. the genetic estimates were assessed by restricted maximum likelihood (reml) procedures using average information algorithm (aireml) in a corriedale flock. the traits analysed were wool colour traits (cwc), yellow predictive colour (ypc), and visual score; suint traits such as suint percentage and potassium and sodium concentrations in suint, and physiological traits such as potassium and sodium concentrations in the skin, including plasma and red blood cells. the objectives of this study were to assess phenotypic and genetic correlations between wool colour and skin traits, and to find the suitability of these traits as indirect selection criteria for clean wool colour. suint traits were highly genetically correlated to ypc. suint k, but not suint percentage, was found to have a high genetic correlation with cwc. skin k, visual score, ypc and suint k were amongst the best indirect selection criteria for clean wool colour. however, selection using these traits was expected to reduce cwc from 52% to 49% of that estimated under direct selection.

In this work heritability, phenotypic and genetic correlations among wool colour and skin traits were examined. The genetic estimates were assessed by Restricted Maximum Likelihood (REML) procedures using average information algorithm (AIREML) in a Corriedale flock. The traits analysed were wool colour traits (CWC), yellow predictive colour (YPC), and Visual Score; suint traits such as suint percentage and potassium and sodium concentrations in suint, and physiological traits such as potassium and sodium concentrations in the skin, including plasma and red blood cells. The objectives of this study were to assess phenotypic and genetic correlations between wool colour and skin traits, and to find the suitability of these traits as indirect selection criteria for clean wool colour. Suint traits were highly genetically correlated to YPC. Suint K, but not suint percentage, was found to have a high genetic correlation with CWC. Skin K, Visual Score, YPC and suint K were amongst the best indirect selection criteria for clean wool colour. However, selection using these traits was expected to reduce CWC from 52% to 49% of that estimated under direct selection.

Abstract: A study is carried out to investigate the concentrations and distribution of trace metals to the sediments of Tamirabarani River, south east coast of India. Nearly sixteen soil samples collected from river mouth and tributaries and analyzed for traces elements show high-rate concentration of Hg (3.52-24.69μg g-1) Cu(2.2-17.82μg g-1), Ni(7.83-15.2μg g-1), Cr(58.3-145.5μg g-1), Pb(3.48-12.93μg g-1), Zn(9.3-74μg g-1) and Cd(1.41-4.92μg g-1). The pH, EC, and TDS values reported as (8.1-9.5) (384-16250) (303-33050) .The abundances of such metals caused by the river contribution of sediments from areas with unplanned agricultural development and from the industrial, activity carried out on the riverbanks. It is concluded that in and around Mukkani area, the concentration of heavy metals is higher due to anthropogenic and industrial effluent in Tamirabarani River.
