GDP and the Value of Family Caretaking: How Much Does Europe Care? This study estimates the size and value of unpaid family caretaking activities at a European level. While at a country level several studies are available, a comprehensive evaluation for Europe as a whole was missing so far, mainly due to data limitations. This paper fills this gap using a method that merges the information of a...

AIM The present study aims to evaluate zootechnic parameters and blood sugar in rabbits submitted to diets containing different levels of pepper (Capsicum frutescens). MATERIALS AND METHODS To this end, 30 rabbits weighing on average 1252±35 g at the beginning of the experiment were subjected to five rations with three repetitions for 56 days: The food R0 (or control) which is floury provende...

BACKGROUND Interstitial lung disease often occurs as an early complication of systemic sclerosis (SSc). The aim was to investigate whether impulse oscillometry (IOS) could be used to evaluate lung impairment in SSc. METHODS Seventy-eight SSc patients, of which 65 had limited cutaneous SSc (lcSSc) and 13 had diffuse cutaneous SSc (dcSSc), were subjected to high-resolution computed tomography (...

Highly imbalanced sex ratios suggest that Asian families prefer sons. This preference may be expressed as reduction in parental investment in daughters when a younger son is born. This study investigates the gender effect of a younger sibling on older daughter's schooling. We construct a unique dataset linking national administrative data on college entrance examinations (CET) to birth registry...

The study on the mechanism of effect temperature decomposition reaction SFn (n = 1–6) under discharge conditions is very important in studying potential fault SF6 high voltage switch equipment and perfecting chemical kinetic model discharge. In this paper, structural optimizations, thermal correction to Gibbs free energy for reactants, products were performed at B3LYP/6–311 + G(d,p) theory leve...

Rainfall and air temperature variability pose the greatest risk to environmental change. Past trends in rainfall facilitate projecting future climate changes for informed policy responses. We used a combination of normalised difference vegetation index (NDVI) observed data from 1968 2017 assess rainfall, moisture stress, over time on bioclimatic regions KwaZulu-Natal (KZN) Province, South Afric...

Economic development and large amounts of industrial production have led to environmental deterioration. The assessment prediction water environment capacity (WEC) are crucial supports for quality target management. Therefore, this study aims improve WEC via changes in the structure analyze economic changes. For purpose, efficiency (EE), use (WUE), treatment (WTE) estimated by EE–SBM (slack-bas...

The thymidine kinases (TKs) of herpes simplex virus type 1 (HSV-1), HSV-2, and varicella-zoster virus (VZV) were expressed in human osteosarcoma cells as fusion proteins with the green fluorescent protein (GFP), and their intracellular localizations were determined. The three TK-GFP fusion products were localized in different subcellular compartments of the transfected tumor cells. HSV-1 TK-GFP...

Enterotoxigenic Escherichia coli associated with human diarrheal disease utilize any of a limited group of serologically distinguishable pili for attachment to intestinal cells. These include CS1 and CFA/I pili. We show here that chemical modification of arginyl residues in CS1 pili abolishes CS1-mediated agglutination of bovine erythrocytes, which serves as a model system for attachment. Alani...

This paper empirically examines the role of social networks in welfare participation. Social theorists from across the political spectrum have argued that network e ects have given rise to a culture of poverty. Empirical work, however, has found it di cult to distinguish the e ect of networks from unobservable characteristics of individuals and areas. We use data on language spoken to better in...
