The deoxyribonucleic acid (DNA) sodium salt was reacted with hexadecyltrimethylammonium bromide (CTMA) to obtain DNA-CTMA organic-solvent soluble complex. The DNA-CTMA was then mixed with three organic dyes such as Nile Blue A (NB), Disperse Red 1 (DR1) and Disperse Orange 3 (DO3) resulting in colored membranes, that were characterized by UV-Vis, FTIR, X-ray, ionic conductivity and fluorescence...
Microbial populations can be dispersal limited. However, microorganisms that successfully disperse into physiologically ideal environments are not guaranteed to establish. This observation contradicts the Baas-Becking tenet: 'Everything is everywhere, but the environment selects'. Allee effects, which manifest in the relationship between initial population density and probability of establishme...
BACKGROUND Disperse dyes are well-known contact sensitizers. However, they are not included in the majority of commercially available baseline patch test series. OBJECTIVES To investigate the outcome of patch testing with a textile dye mix (TDM) consisting of eight disperse dyes at dermatology clinics in various countries. PATIENTS/MATERIALS/METHODS Two thousand nine hundred and seven conse...
Improving Water Sustainability and Food Security through Increased Crop Water Productivity in Malawi
Agriculture accounts for most of the renewable freshwater resource withdrawals in Malawi, yet food insecurity and water scarcity remain as major challenges. Despite Malawi’s vast water resources, climate change, coupled with increasing population and urbanisation are contributing to increasing water scarcity. Improving crop water productivity has been identified as a possible solution to water ...
OBJECTIVE To analyze the sulfur content of water and forage samples from a geographically diverse sample of beef cow-calf operations in the United States and to estimate frequency and distribution of premises where forage and water resources could result in consumption of hazardous amounts of sulfur by cattle. DESIGN Cross-sectional study. SAMPLE POPULATION 709 forage samples from 678 beef ...
Forty-two consulting feedlot nutritionists were asked to participate in a survey regarding nutritional recommendations for feedlot cattle. Eleven nutritionists chose not to participate or did not reply to our request. Thirty-one nutritionists agreed to participate, and 29 completed the survey. Their practices were located in the following states: Texas, Kansas, and Oklahoma (46.43%); Iowa, Nebr...
Recent energy security strategies, investment opportunities and energy policies have led to an escalation in biofuel consumption at the expenses of food crops and pastureland. To evaluate the important impacts of biofuels on food security, the food-energy nexus needs to be investigated in the context of its linkages with the overall human appropriation of land and water resources. Here we provi...
