soil erosion is one of the most important forms of land degradation that threatens continued and sustained agricultural production in ghana. the most severely affected areas are the three northern regions especially upper east region, where large tracts of land have been destroyed by water erosion leading to soil depth reduction and decline in soil fertility. this study was carried out in talen...

Compact numerical schemes provide high-order solution of PDEs with low dissipation and dispersion. Computer implementation of these schemes requires numerous passes of data through cache memory that considerably reduces performance of these schemes. To reduce this di culty, a novel algorithm is proposed here. This algorithm is based on a wavefront approach and sweeps through cache only twice.

This paper puts forward a verification method for compound purposes and compound reasons to be used during purpose limitation. When it is absolutely necessary to collect privacy related information, it is essential that privacy enhancing technologies (PETs) protect access to data – in general accomplished by using the concept of purposes bound to data. Compound purposes and reasons are an enhan...

This article argues that legal determinations of filiation are normative ideological constructions about how societal relations between parents and children should be ordered. They are based upon regular understandings of the relationship between biological and social facts and, as this article demonstrates, operate to create an asymmetrical relationship between the categories between paternity...

Alternative methods of treating psychological stress are needed to treat some veterans of recent military conflicts. The use of virtual world technologies is one possible platform for treatment that is being explored by the “Coming Home” project at the University of Southern California’s Institute for Creative Technologies (ICT). One of the novel ways ICT is attempting to mitigate stress via vi...

The aberration field of an optical system with a tilted pupil is explored through expanding the vector expressions of the third-order wavefront aberrations. First, the vector forms of the wavefront aberrations are modified to obtain the aberration expressions with the pupil tilted; full field displays of coma and astigmatism in this situation are given. Then, the third-order aberration formulas...

This study examines how the non-targeted earned income tax credit (EITC) introduced in Sweden in 2007 has affected the labor supply of men and women living together in two-adult households and the extent to which children affect related outcomes. Using a structural discrete labor supply model for two adult households, we estimate the impact of the EITC on both labor supply and disposable income...

In vitro fertilization, popularly referred to as IVF, has captured the attention of the public since its sensational introduction in 1978. Today assisted reproductive technology is available throughout most of the civilized world, and the practice is largely different from that used during the early days. Refinements in laboratory technology and clinical practice have allowed IVF to evolve into...

Lineage in the Islamic law is one of the most basic human rights each individual inherits from his family. When modern assisted reproductive technologies appeared in recent decades, the issue of lineage and the child's rights did not encounter serious challenges. But with the advent of these technologies, the issue of the child's lineage resulting from new technologies has become the center of ...
