Fertility patterns in the Roma population of Spain

The Spanish Roma population have co-existed with the broader population of Spain, under the same laws and regulations for more than 500 years, but they exhibit very different fertility patterns. The aim of this paper is to determine whether there are factors other than income or education that can explain the larger number of children in Spanish Roma families. Our analysis reveals that the existence of a family business, which is highly labor-demanding, appears to be associated with parental decisions concerning the number of children. Since parental authority, in Roma families, holds sway over children even after their own marriage, the future labor contributions of children are particularly beneficial to the family business

Pengaruh Penambahan Pektin Kulit Pisang Kepok (Musa paradisiaca l.) Terhadap Karakteristik Fisiko-Kimia Sari Buah Naga Merah (hylocereus polyrhizus.)

The research aims to determine the effect of pectin from kepok banana peel as a stabilizer in red dragon fruit juice. The research applies Completely Randomized Design (CRD) with one factor, namely concentration of addition of pectin from kepok banana peel. The research factor comprises 4 levels, namely the concentration of addition of pectin from kepok banana peel (S0-banana peel pectin for 0 g. S1-banana peel pectin for 0.5 g. S2-banana peel pectin for 1 g, and S3-banana peel pectin for 1.5 g) and each treatment is repeated three times. Observation parameters consist of total dissolved solid, viscosity, pH, stability, and organoleptic. As a result, a significant effect is observable in the parameters of total dissolved solid, viscosity. and pH. On average, the panelists prefer the color of fruit juice with the addition of 1.5 g of banana peel pectin, which is 5,77 (like). In the meantime, an increase in the concentration of the addition of kepok banana peel pectin also increases the parameter values for total soluble solid ranging from 21.40 Brix, viscosity for 3550cp, and pH for 7.27%.

S-100a0 protein stimulates Ca2+ -induced Ca2+ release from isolated sarcoplasmic reticulum vesicles

AbstractS-100a0 protein, the αα-isoform of the S-100 family, stimulates Ca2+ -induced Ca2+ release from terminal cisternae isolated from rat skeletal muscle cells. The stimulatory effect of S-100a0 is maximal at ∼5 μM S-100a0 and half maximal at ∼0.1 μM S-100a0, at 1.8 μM free Ca2+ in the presence of 5 mM Mg2+ plus 0.1 M KCl. The effect of the protein on Ca2+ -induced Ca2+ release is completely inhibted by the calcium release blocker, ruthenium red

El diagnóstico serológico de la leishmaniosis canina en la comarca del Priorat (Tarragona)

Se investiga la presencia de anticuerpos anti-Leishmania mediante una técnica de «Dot-ELISA» en 1.328 muestras de sangre procedentes de 902 perros de la comarca del Priorat (Cataluña), importante foco de leishmaniosis canina. El umbral de positividad para la mencionada técnica (11800) se establece a partir de los datos obtenidos al realizar en paralelo cultivo y serología. Los resultados serológicos obtenidos permiten observar una tasa de prevalencia de la infección de 10,2%. Tan sólo el 49,8 % de los sueros estudiados son totalmente negativos. Al 40 % restante se le detecta anticuerpos anti-Leishmania a títulos inferiores al umbral establecido cuyo posible significado se discute.The presence of anti-Leishmania antibodies is studied in 1328 blood samples from 902 dogs from the Priorat region (Catalonia), an important focus of canine leúhmaniosú, by a Dot-ELISA technique. The cut-off (1/800)is established through the data obtained by serology and culture in parallel. The prevalence of seropositives observed was 10,2 %. Only 49,8 % of sera were completely negative. The remaining 40% had anti-Leishmania antibodies at titres below the cut- off, the possible significance of which is discused

Pollution, Public Health Care, and Life Expectancy When Inequality Matters

We analyze the link between economic inequality in terms of wealth, life expectancy, health care and pollution. The distribution of wealth is decisive for the number of households investing in human capital. Moreover, the willingness to invest in human capital depends on agents' life expectancy which determines the length of the amortization period of human capital investments. Life expectancy is positively affected by public health care expenditures but adversely affected by the pollution stock generated by aggregate production. Our model accounts for an endogenous take-off in terms of human capital investments. Higher initial inequality delays the take-off because a given set of policies (abatement measures and public health care) is less effective in improving agents' survival probabilities. We compare a change in taxes to a change in expenditure shares on health hand abatement given different amounts of (initial) inequality. The advantage of the latter as compared to the former is the achieved increase in the tax base which induces more expenditures on health care and abatement measures, such that an even higher economic activity is compatible with a similar level of long-run pollution

Analysis of the potential for hydrogen production in the province of Córdoba, Argentina, from wind resources

The potential for hydrogen production from wind resources in the province of Córdoba, second consumer of fossil fuels for transportation in Argentina, is analyzed. Three aspects of the problem are considered: the evaluation of the hydrogen resource from wind power, the analysis of the production costs via electrolysis and the annual requirements of wind energy to generate hydrogen to fuel the vehicular transport of the province. Different scenarios were considered, including pure hydrogen as well as the so-called CNG plus, where hydrogen is mixed with compressed natural gas in a 20% V/V dilution of the former. The potential for hydrogen production from wind resources is analyzed for each department of the province, excluding those regions not suited for wind farms. The analysis takes into account the efficiency of the electrolyzer and the capacity factor of the wind power system. It is concluded that the automotive transportation could be supplied by hydrogen stemming from wind resources via electrolysis. © 2009 Professor T. Nejat Veziroglu. Published by Elsevier Ltd.
