A multiple of stakeholder goals, regarding natural resource utilisation, are integrated into an overall provincial strategic forest and fisheries utilisation decision support system providing a platform for defining tactical forest planning objectives within a 10-year planning horizon. The case study area is a 5362 ha mangrove forest enterprise, divided into a buffer zone and a full protection ...

Riparian buffers, the vegetated region adjacent to streams and wetlands, are thought to be effective at intercepting and reducing nitrogen loads entering water bodies. Riparian buffer width is thought to be positively related to nitrogen removal effectiveness by influencing nitrogen retention or removal. We surveyed the scientific literature containing data on riparian buffers and nitrogen conc...

Introduction: Stroke is the third important reason of death in adults and an important cause of adult disability. Previous studies suggest that TGF-alpha can induce neurogenesis after stroke. Here in, we studied neurogenesis effects of the TGF-alpha on subventricular zone following ischemia-reperfusion. Male wistar rats (250-300 g) were divided into ischemia and treatment groups. After inductio...

The investigation on capillary electrophoretic enantioseparation of six synthetic compounds containing vicinal diol groups has been undertaken to acquire the optimum conditions using native beta-cyclodextrin (beta-CD) as chiral selector and borate as a background electrolyte. The separation was carried out in an uncoated capillary (58.5 cm x 75 microm i.d., effective length 48.5 cm) and the eff...

A new, versatile, multiphasic buffer system for high-resolution sodium dodecyl sulfate-polyacrylamide gel electrophoresis of proteins in the relative molecular weight range of 300 000-3000 Da is described. The system, based on the theory of multiphasic zone electrophoresis, allows complete stacking and destacking of proteins in the above M(r) range. The buffer system uses taurine and chloride a...

Capillary electrophoresis can be used successfully to analyse small peptides to give additional information to that obtained using high-performance liquid chromatography (HPLC). The separation of a modified adrenocorticotropic hormone (4-9) fragment (Org 2766) and several of its fragments was investigated using capillary zone electrophoresis. Prediction of migration in aqueous systems using pKa...

Synthetic food dyes were separated by capillary zone electrophoresis using an alkaline phosphate buffer as background electrolyte. The precision had a relative standard deviation of less than 0.5 % for the run-to-run migration times and 2 % for the peak areas with buffer replenishment after each run. The detection limit for the individual dyes was about 1 ng using a 50-μm internal diameter Agil...

Conclusions: The effects of new outdoor tobacco advertising restrictions vary by location and population density. InMissouri andNewYork, outdoor tobacco advertising would still be permitted in many locations if such advertising was prohibited in a 1000-foot buffer zone around schools and playgrounds. Much smaller buffer zones of 350 feet may result in almost no reduction of outdoor advertising ...
