The Effect of Active Transport on the Movement of Glucose Against the Concentration Gradient within the Small Intestine of a Rat Introduction The movement of substances across the cell membrane occurs in many ways, including transport by carrier proteins, also known as active transport (Barman et al. 1986). Active transport involves the movement of molecules through the cell membrane against a concentration gradient with the help of a carrier protein utilizing ATP energy. (Barman et al. 1986).…

The Hohokam culture of the Sonoran Desert lasted from about AD 50 to AD 1450 hitting its peak at around AD 950. They are well known for many aspects of their culture, but the feature that most likely lead to their large populations and lasting culture was their irrigation canal systems. The Hohokam were focused primarily around the Salt and Gila rivers of Southern Arizona as depicted in Figure 1. The massive canal systems that they build off of these rivers allowed for the support of a large…

After working in the French Creek Watershed I began to hike around the lakes and streams. This means by having cleaner streams I would personally benefit from aesthetically pleasing clean streams. Even on a short weekend walk behind the cemetery I would pick up any bottles or small objects I saw I felt an obligation to give back to the area I was able to enjoy. I also understood it was vital to keep the area clean so it would stay enjoyably and inhabited by the animals I always hope to see.…

Evaluating the benefits and problems associated with malolactic fermentation of Merlot wines Emma Bruwer, 16122364, BSc Agric (Viticulture and Oenology), J.H Neethling Building, Victoria Street, Stellenbosch University. Rudi Scholtz, Thelema Mountain Vineyards, Helshoogte Pass, Stellenbosch. August 2015 ABSTRACT Malolactic fermentation is the conversion of harsh and acidic malic acid to a more desirable form of lactic acid in wine by Lactic acid bacteria, after the completion of alcoholic…

acids being noticeable. However, other types of fat will only have three saturated and two unsaturated fatty acids in abundance in their structures (McWilliams, 2009). In bakery productions, fat are functions a shortening power and lubricity, batter aeration,…

Title: Methylcobaloxime: A Model for Vitamin B12 Aim: To create methyl(pyridine)cobaloxime(III) as a model for methylCobalamin, the methylated form of vitamin B12, Introduction: Using Co(I)Cl2 as a starting material, it is possible to produce a cyano(pyridine)cobaloxime like compound, Chloro(pyridine)cobaloxime whose chemistry can be investigated via means of methylation, as such using the Chloro(pyridine)cobaloxime as a model for replicating chemistry already known of…

Fermentation has been used by mankind for centuries to make useful products such as cheese, breads, yogurts and alcohol beverages. During fermentation, some strains of yeast decompose sugars to derive energy, and in the process they produce ethanol as a waste product. When bread dough is being made, yeast is added to make dough rise. This occurs because the yeast ferments sugar releasing carbon dioxide which causes the dough to rise and creates holes in the bread. This carbon dioxide released…

should be between 6 to 7 as optimum level to culture the frys. 3. Currents The water currents shall not be too strong. Since newly hatched frys are not be able to swim like adults do, weaker currents is enough to allow them to maintain their position. Aeration should be slower (not strong ones). 4. Temperature To accelerate the growth rate, temperature at 14℃ is used…

biological activities (Martens, 2001). As main channels for N losses, N volatilization, leaching and denitrification become prominent when N mineralization activity occurs under favourable conditions for these N losses. Tillage provides necessary aeration and optimum moisture for soil microbial decomposition of SOM, thus the practice likely results in promoting the loss of soil organic N. Due to N conservation awareness and increased fuel costs, no-till has been widely implemented to conserve N…

VOLUMETRIC EVALUATION OF THE PARANASAL SINUSES WITH THE CAVALIERI METHOD SUMMARY PURPOSE Our aim was to estimate the volumes of paranasal sinuses with Cavalieri principle. MATERIAL AND METHODS The volumes of paranasal sinuses were estimated using the Cavalieri principle with coronal CT scans of 125 (68 male and 57 female) cases and analyzed by gender and age. The right-left comparison was also researched. RESULTS The mean volumes (± S.D.) of unilateral sinuses were 6.0 ± 4.3, 19.1 ± 6.1,…
