Abstract: objective: catalonia and the basque country received substantial immigration quotas from the rest of spain during the twentieth century. this study aimed to analyze inequalities in health by birthplace (the population born in the same region or other autonomous regions) in these two geographical areas. methods: we conducted a cross-sectional study in the non-institutionalized population aged 50 to 79 years, with data from the health surveys of catalonia 2006 (n=5,483) and the basque country 2007 (n=3,424). we used log-binomial models to estimate the prevalence ratios (pr) of poor self-rated health by birthplace, stratified by sex and social class, and successively adjusted for age, social class and educational attainment. results: immigrants from other autonomous regions had poorer self-rated health than the native-born population, both in the basque country (age-adjusted pr in men 1.30, 95% ci 1.11-1.54; women 1.42, 95% ci 1.25-1.62,) and in catalonia (pr in men 1.41, 95% ci 1.26-1.62; pr in women 1.25, 95% ci 1.16-1.35). prs were reduced but remained significant after adjustment for social class and educational attainment and stratification by manual or non-manual social class. conclusions: in both communities there are health inequalities that are detrimental to the immigrant population from the rest of spain, which constitutes approximately half of the population in the studied age cohorts. future studies should explore the persistence of these inequalities in other health indicators and their reproduction in second generations, and identify entry points for preventive policies.
Influence of MeV H+ ion beam flux on cross-linking and blister formation in PMMA resist

Maejo International Journal of Science and Technology , 2012,
Abstract: In soft lithography, a pattern is produced in poly(dimethylsiloxane) (PDMS) elastomer by casting from a master mould. The mould can be made of poly(methylmethacrylate) (PMMA) resist by utilising either its positive or negative tone induced by an ion beam. Here we have investigated the irradiation conditions for achieving complete cross-linking and absence of blister formation in PMMA so that its negative characteristic can be used in making master moulds. PMMA thin films approximately 9 μm thick on Si were deposited by spin coating. The 2-MeV H+ ion beam was generated using a 1.7-MV tandem Tandetron accelerator. The beam was collimated to a 500×500 μm2 cross section using programmable proximity aperture lithography system with a real-time ion beam monitoring system and a high precision current integrator. The irradiated areas were investigated by a standard scanning electron microscope and a profilometer. It was found that both the ion beam flux and the stopping power of the ions in the polymer have a critical influence on the blister formation.

Malmusi,Davide; Jansà i Lopez del Vallado,Josep Maria;
Revista Espa?ola de Salud Pública , 2007, DOI: 10.1590/S1135-57272007000400007
Abstract: background: the growth of the foreign population residing in spain makes it necessary to avail of better information on the level of health. in the health information and research systems, no uniform criteria currently exist for the nomenclature of origin-related variables. this study poses a consensus on the definitions of immigrant and foreigner. methods: employing the delphi methodology, 66 experts in immigration from different disciplines were invited to take part in the study using a two-round questionnaire with suggested definitions, terms and variables, including in the second round the percentages of responses and the comments made by the participants in the first. the suggestions regarding which an 80% consensus was reached were put into a final document which was approved in the third round. results: a total of 57 people accepted the invitation, 44 having completed at least one round and 33 having completed all three. some of the most important aspects regarding which a consensus was reached were: the term "immigrant" denotes the individual who comes to a country where he/she was not born to take up residency, one not being an immigrant on a lifelong basis. those individuals born in another country who have arrived in spain less than 5-10 years ago can be considered immigrants; and immigrated people are all those individuals born in another country. socioeconomic variables, gender, administrative status and country of origin should also be taken into consideration. the children of immigrated individuals who are born in spain must not be considered individuals who are born in spain must not be considered. conclusions: to properly define the inmigrating and immigrated population categories, the health studies and information systems must include country of birth, year of arrival and nationality.

Abstract: stenocereus griseus and cereus repandus are two of the most abundant and widely distributed columnar cacti in the arid and semiarid regions of venezuela. despite their value as keystone species for wildlife and their potential economic value, information on their reproductive activity and regeneration capacities is quite limited. these aspects were evaluated in natural populations from padre diego, lara state, and paraguana peninsula, falcon state. these cacti have broad time windows for reproduction and considerably high fecundity levels (s. griseus: 44,225 seeds/ind, c. repandus: 322,749 seeds/ind), which confer them great advantages in terms of natural regeneration and propagation. these species depend on nurse plants for their establishment. the highest percentages of survival occurred under the shadow of trees. under natural conditions, these species can produce half a ton of fruit pulp per hectare.

Abstract: Stenocereus griseus y Cereus repandus son dos de las cactáceas columnares más abundantes y ampliamente distribuidas en las regiones áridas y semiáridas de Venezuela. A pesar de su valor como especies clave para la fauna silvestre y de su potencial valor económico, la información sobre su actividad reproductiva y capacidad de regeneración es muy limitada. Dichos aspectos fueron evaluados en poblaciones naturales de Padre Diego, estado Lara y la Península de Paraguaná, estado Falcón. Estos cactus poseen patrones reproductivos temporalmente amplios y niveles de fecundidad elevados (S. griseus: 44.225 semillas/ind, C. repandus: 322.749 semillas/ind), que les confieren grandes ventajas para su regeneración natural y propagación. Estas especies dependen de plantas nodriza para su establecimiento, presentando los porcentajes más elevados de supervivencia bajo la sombra de árboles. En condiciones naturales, estas plantas rinden media tonelada de pulpa de fruta por hectárea.

Archivos Latinoamericanos de Nutrición , 2006,
Abstract: this study aimed to examine the possibility of producing marmalades from the fruit pulp of the red and white varieties of cardón dato (stenocereus griseus). we developed the formulations of the marmalades and evaluated their stability during three months of storage at room temperature. as first step, we characterized the fruits of the two color varieties, observing that despite the considerable difference between both color varieties, there were no significant differences in average weight, dimensions and proportion of pulp, skin and seeds. the pulp of the two color types had high ph (5,2) values and low contents of reductor sugars (3,59 g/100g white variety 2,23 g/100g red variety), non reductor sugars (0,75 g/100g white variety and 2,03 g/100g red variety), pectin (0,14 g/100g white variety and 0,23 g/100g red variety) and acids (7,67 g/100g white variety and 0,15 g/100g red variety). it is needed to include sugar, pectin, and citric acid in the marmalade formula. the first marmalades produced were gummy, a problem that we solved adding the acid from the beginning of the making process. during the three months of storage, the marmalades had good acceptance by the evaluators, this despite slight fluctuations observed in ph, solid contents, and acidity.
Emaús, a charity organization

Abstract: Emaús Bilbao Cooperative Company is a social economy and solidarity organization for socio-labour insertion. It is dedicated to the comprehensive management of solid urban waste. It has its headquarters in Bilbao and carries out its work in Vizcaya.From 1970, the year in which Emaús established itself in Vizcaya, to the present day, the organization has experienced an evolution which has led it to change its management direction. Gone are the days when they were only known as “the rag and bone men of Emaus” with all the connotations that were associated with that name. At present we find a company which has adopted new management formulas without losing the characteristics of its social and solidarity project. This has enabled it to face up to the prevailing conditions in todays economic climate. In this way it has been able to guarantee its survival.The comprehensive management of solid urban waste is made up of four diverse parts: The location of the urban solid waste through the receiving of telephone calls, its collection and selection, and the final elimination of those things that can not be incorporated again into the consumer chain. Through this case, the problems that arise for the organization with reference to the management of Human Resources are analysed. These are related above all to the motivational and decision making aspects due to the diverse characteristics as much in their own workers as in the organization.
