Aeration

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,…

Many of us would like to understand what Arsenic is and why this element is in our drinking water. To begin with our introduction to Arsenic, we should all understand that it is a semi-metal element from the periodic table that we are mostly familiar with. It is odorless and has no type of specific taste to the human tongue. It is mostly sourced from natural deposits in the Earth, however, it’s also known to be sourced from agricultural and industrial practices all over the world. It is simply…

Application of Biofloc technology in aquaculture systems; a viewpoint Anjali P. Thilakan1*,Manju Lekshmi. N2.,Sreekanth.G.B2, N. P. Singh2 1Central Institute of Fisheries Education, Andheri (W), Mumbai 2ICAR Central Coastal Agricultural Research Institute, Ela, Old Goa . Abstract Bioflocs are aggregates (flocs) of algae, bacteria, proto¬zoans, and other kinds of particulate organic matter such as feces and uneaten feed and it normally contains 35-40% of protein. Biofloc technology ensures…

Chapter 3 Experimental Setup 3.1 Test rig components and description: Fig. 3 illustrates schematic view of the test rig of an IDX-SAHP system. It was designed for a typical UK home administering up to 350 L/day of DHW. The main components are numbered in (Fig.3). The evacuated tube collector installed outdoor on a south facing roof has a surface area of 3.021 m2 with a 52-degree inclination (tilt angle). A 300L, stainless steel, insulated water storage tank has two coils immersed inside, one for…

According to Schouten et al (2008), sepsis involves the activation of the coagulation cascade coupled with down-regulation of anticoagulation and fibrinolysis. An intricate link between inflammation and coagulation exists within the body (Neligan, 2006). When a pathogen is present in the bloodstream or when tissue injury occurs, an inflammatory response occurs. The response causes a stimulation of the immune system to produce interleukin-1 (IL-1), interleukin-6 (IL-6) and tumor necrosis…
