RATIONALE, AIMS AND OBJECTIVES This paper is the third of three related papers exploring the ways in which the principles of Learning Organizations (LOs) could be applied in Primary Care settings at the point of service delivery. METHODS Here we provide a systematic literature review of contextual factors that either play a key role in providing a facilitative context for a Learning Practice ...

A range of N-protected-alpha-amino acyl-5,7-dinitroindolines 3a-z were prepared in good yields from commercially available N-protected-alpha-amino acids 1a-z by a two-step sequence of acylation and intramolecular amide N-arylation. Subsequent photochemical acylation of the N-protected-alpha-amino acyl-5,7-dinitroindolines 3e,g,r afforded the corresponding N-protected-alpha-amino acid amides 22e...

NATHAN L. STEPHENSON, CONSTANCE 1. MILLAR, AND DAVID N. COLE ex:panding human impacts suggest that hUlllan intervention in ecosystems may be essential to protect critical values in parks and wilderness areas. Ecological restoration has moved toward the forefront of stewardship policY and practice. As a case in point, National Park Service (2006: 37) management policies call for the restoration ...

While enzymes are valuable tools in many fields of biotechnology, they are fragile and must be protected against denaturing conditions such as unfavorable solution pH. Within living organisms, chaperonins help enzymes fold into their native shape and protect them from damage. Inspired by this natural solution, mesoporous silica SBA-15 with different pore diameters is synthesized as a support ma...

The challenges of managing natural resources of protected areas not only come from the inside of the protected boundaries, but also from the surrounding territories because most of protected lands are open systems that face threats from adjacent areas. The lands of such open systems alter water quality and flow regimes, increase the likelihood of invasive plant and animal range expansions, redu...

PURPOSE In this research the effect of vitamin B1 and B6 on cyanocobalamin stability in commercial light protected parenteral formulations and upon adding stabilizing agents will be investigated and best formulation composition and proper storage condition will be introduced. METHODS In this research some additives such as co solvents and tonicity adjusters, surfactants, antioxidants and chel...

Protected areas are the dominant approach to protecting biodiversity and the supply of ecosystem services. Because these protected areas are often placed in regions with widespread poverty and because they can limit agricultural development and exploitation of natural resources, concerns have been raised about their potential to create or reinforce poverty traps. Previous studies suggest that t...
