Cyclic changes in the shape of a quasi-rigid body on a curved manifold can lead to net translation and/or rotation of the body. The amount of translation depends on the intrinsic curvature of the manifold. Presuming spacetime is a curved manifold as portrayed by general relativity, translation in space can be accomplished simply by cyclic changes in the shape of a body, without any external for...

The wrist is one of the most intricate articulations of the musculoskeletal system, in which the delicate balance is maintained by a complex set of intrinsic and extrinsic ligamentous connections between seven carpal bones. Injuries to the bones and ligaments in the wrist may potentially irreversibly disrupt this balance and initiate progressive degenerative disease and osteoarthritis (OA). Mus...

We use both a string and a field theoretical approach in order to determine respectively the Kähler metrics of untwisted and twisted open strings attached to magnetized D9 branes in toroidal compactifications. Work partially supported by the European Community’s Human Potential Programme under contract MRTN-CT-2004-005104 “Constituents, Fundamental Forces and Symmetries of the Universe”.

General morphological analysis (GMA) is a method for structuring and analyzing the total set of relationships contained in multi-dimensional, non-quantifiable problem complexes, and for synthesizing solution spaces. During the past 15 years, GMA has been extended, computerized and applied by the Swedish Defence Research Agency (FOI) for scenario development, long-term strategy management and or...

Agribusiness industries are facing numerous challenges and opportunities resulting from various fundamental forces. An understanding of the forces that are shaping and shifting the competitive landscape is useful to not only understand the strategic positioning decisions of the firms in these industries, but also the dramatic structural changes that are occurring in the food production, process...

Highly entitative sub-groups with strong ideologies ensure members are committed to the groups cause making disengagement a significant life event. This paper provides an insight into the current study of the psychological and social factors influencing the experience of personal disengagement from HESGIs. Semi-structured interviews were held with former members of one percent motorcycle clubs,...

This paper presents the preliminary findings of research into the disengagement from highly entitative and ideological social groups, such as one percent motorcycle clubs, military special forces and fundamental ideological groups. Using a grounded theory approach, the discourse of 25 former members identified the discrepancy between group membership and the self-concept as the core theme in th...

(thank you Brian, Roni, Paddy for putting together a wonderful workshop ! Workshop addressed issues of light dark matter and " dark forces " –possible new interactions of dark sector)

The presented here instructional model is based on two premises derived from psychological and learning theories. The first is that students take greater control on their own learning, which implies active learning where the instructor acts as a mentor. The second is that the learning environment enables interplay between the extrinsic forces acting on learners and the intrinsic motives and nee...

BACKGROUND Actomyosin contractility is the major cellular force driving changes in cell and tissue shape. A principal regulator of contractility is the small GTPase RhoA. External mechanical forces have been shown to impact RhoA activity and cellular contractility. However, the mechanotransduction pathway from external forces to actomyosin contractility is poorly understood. RESULTS Here, we ...
