which allows some, but not all, substances to pass. In solutions, when the liquid solvent passes through the membrane but the solute (dissolved solid) is retained, the process is calledosmosis. Diffusion of a solute across a membrane is calleddialysis, especially when some solutes pass and oth...
Odorants in aquatic environments, in particular oceans and rivers, move in intermittent and filamentous plumes, caused by the turbulent motion of the fluid. The challenges to studying chemosensory guided search are quantitatively understanding chemical transport and how organisms filter information to track...
A two-dimensional diffusionreaction model which allows for diffusive rather than advective transport within stagnant, water-filled burrows demonstrates that, in the absence of advective irrigation, relict burrow structures are unlikely in most cases to significantly alter average solute distributions from ...
various contexts underscores the importance of continued research and development in this rapidly evolving field. DNA-tagging technology At present, several technologies are used to enable the tagging of physical objects, such as universal product code (UPC) barcoding, radio-frequency identification (...
production technology, while the biomass energy domain has a strong interest in the process of processing biomass. The results reveal that different communities have different ideas about research, resulting in a divide in the areas to be achieved. This comparative analysis reveals the importance of ...
Corkum, 1990, Corkum, 1991, Corkum, 1992 highlighted the importance of the surrounding landscape features in determining the distribution of macroinvertebrate communities, demonstrating that similar assemblages occur at different river sites surrounded by the same biome when characteristic vegetation is not ...
The time-kill (TK) assay is considered the gold standard method for the evaluation of in vitro synergy, but it is a time-consuming and expensive method. The purpose of this study was to evaluate two methods for testing in vitro antimicrobial combinations: the disk diffusion method through ...
(VoFrAs). This variable is not frequently reported, but there is a highly consistent decrease with increasing light intensity. Although a densely packed leaf will increase the photosynthetic machinery per unit leaf area, it may at the same time complicate the diffusion of CO2from the stomates ...
Complexity, defined as the number of parts and their degree of differentiation, is a poorly explored aspect of macroevolutionary dynamics. The maximum anatomical complexity of organisms has undoubtedly increased through evolutionary time. However, it is
Of the estimated five million species of fungi, less than 100 species are frequent agents of human disease, and most deaths are due to organisms within the generaCandida,AspergillusandCryptococcus3. However, a cadre of new emerging pathogens are rising in clinical importance, and these include som...
