The rare decay KL → πνν̄ is dominated by direct CP violation and can be computed with extraordinarily high precision. In principle also a CP conserving contribution to this process can arise within the Standard Model. We clarify the structure of the CP conserving mechanism, analyzing both its short-distance and long-distance components. It is pointed out that the calculation of the CP conserving...

A stochastic cellular automaton exhibiting a parity-conserving class transition has been investigated in the presence of quenched spatial disorder by large-scale simulations. Numerical evidence has been found that weak disorder causes irrelevant perturbation for the universal behavior of the transition and the absorbing phase of this model. This opens up the possibility for experimental observa...

Sustainable consumption is one of the goals ‘Sustainable Development Goals 2030′ set by United Nations. The study primarily interested in how sustainable behavior can be fostered through environmental knowledge, behaviors, and attitudes. For concern, role knowledge considered significant. Therefore, academia powered desire to impart environmentally friendly attitudes behaviors students for cons...

BACKGROUND Exposure of lactating women to environmental cigarette smoke may increase cotinine in breast milk, which in turn may reduce the volume of milk and the duration of breastfeeding. OBJECTIVES To assess the relationship between exposure to environmental cigarette smoke and breastfeeding behavior. MATERIALS AND METHODS This prospective cohort study was conducted on 290 mothers in Babo...

Research on environmental behavior highlights the role of information systems in the information acquisition and attitude formation process. Computer-mediated social networks (CMSNs) are forms of social structures that support social activity through computer-mediated communication and interactions. CMSNs can have an influential effect on social norms surrounding various issues, including envir...

The paper examines the Porter and induced-innovation hypotheses in a firm model where: (i) the firm has a vintage capital technology with two complementary factors, energy and capital ; (ii) scrapping is endogenous; (iii) technological progress is energy-saving and endogenous through purposive R&D investment; (iv) the innovation rate increases with R&D investment and decreases with complexity ;...

As sustainable waste management has become an important environmental concern, growing emphasis is being given to policy tools aimed at increasing recycling behavior by households. Information is a common policy tool, but may not always reach the individuals whose behavior is being targeted, i.e., those reluctant to recycle. This study examined individual differences in attention to recycling i...

The intestine carries out important functions related to digestion and absorption. It is composed of three distinct layers, an outer muscle layer, a mesenchymal layer and the epithelial layer. The epithelial layer forms the protective barrier that faces the luminal content of the intestine. In order to maintain barrier function the epithelial layer needs constant replenishment. This is ensured ...
