The pull-back, push-forward and multiplication of smooth functions can be extended to distributions if their wave front set satisfies some conditions. Thus, it is natural to investigate the topological properties of these operations between spaces D′ Γ of distributions having a wave front set included in a given closed cone Γ of the cotangent space. As discovered by S. Alesker, the pull-back is...

Long-term production planning design is a major step in mine planning, because it determines the economic outcome of a project. Also long-term planes act as a guide for medium and short-term production scheduling. Because there are a large number of blocks within the ultimate pit limit, the pit can be divided into a series of sub-pits commonly called push backs, cut backs or phases. These push ...

We have assessed the influence of different surgical procedures on the incidence, severity and duration of early postoperative hypoxaemia in 312 healthy infants and children undergoing elective palatoplasty. Group 1 patients underwent von Langenbeck palatoplasty (n = 149), group 2 patients underwent push-back palatoplasty (n = 124) and group 3 patients underwent combined push-back palatoplasty ...

Push-up exercises are normally performed to challenge muscles that span upper extremity joints. However, it is also recognized that such exercises provide an effective means by which to challenge muscles of the “core”, especially when the hands are in contact with a labile support surface (Freeman et al., 2006). The purpose of this study was to compare trunk muscle activation levels and resulta...

Abstract Since 2000, many African countries have adopted land tenure reforms that aim at comprehensive registration (or certification) and titling. Much work in political science the advocacy literature identifies recipients of certificates or titles as ‘programme beneficiaries’, scientists modelled titling programmes a form distributive politics. In practice, however, rural are often divisive ...

Objective- We assessed the effect of change in core isometric strength and endurance on upper limb isometric strength in female athletes. Methods- In this experimental study, 32 female athletes aged 18-25 years were recruited based on the inclusion criteria. (17 cases in the experimental group and 15 cases in the control group). Before and after the core stabilization knockdown protocol, parti...

The purpose of this study was to investigate joint kinematics of the kicking leg in Taekwondo and to examine the role of inter-joint coordination of the leg in producing the kicking velocity. A new inter-joint coordination index that encompasses three- dimensional hip and knee motions, was defined and applied to the joint kinematic results. Twelve elite Taekwondo athletes participated in this s...

The progressive privatization of Internet infrastructure in the U.S. throughout the 1990s fostered the resurgence of a mass media-style "pipeline" model of online content distribution favored by the media and entertainment industries. Nonetheless, and despite various attempts at suppression by corporations and law enforcement, a diverse community of artists, activists and citizens has found the...
