In mass spectrometry, organic molecules that are present in the gaseous state are bombarded with a beam of energetic electrons (70eV). During bombardment pressure is maintained between 10-7 to 10-5 and electrically heated tungsten or rhenium filament is used for producing beam of electrons. Cations and many other fragments are produced due to the breakdown of the molecules. Cations further breakup to produce smaller ions. In the electric field, all these ions are accelerated and in the variable...
We plan to design and evaluate multi agent control for microscopic robots ("Nanorobots") aiding the surgical repair of damaged nerve cells. This repair operates on both nerves as a whole, at scales of hundreds of microns, and individual nerve cell axons, at scales of about a micron. We match the robots to these sizes using a combination of Micro Electro Mechanical (MEMS) Machines for the larger operations and nanorobots for operations on individual cells. Multi agent control allows...
Is the current rapid decline in the variety of life on Earth, largely attributed to the effects of human culture. In my essay I'm going to give a broad overview of the plight biodiversity is facing currently & mitigate the issues that need to be addressed. Biodiversity can be found at 3 varying levels: genetic diversity, species diversity & ecosystem diversity. Interactions between the 3 are vital to human welfare. Major threats facing biodiversity are; habitat destruction, introduced...
In vitro and in vivo studies suggested that reduced astrocytic uptake of neuronally released glutamate, alterations in expression of glial fibrillary acid protein (GFAP), a major component of the glial filament network, and aquaporin-4 (AQP-4), a water channel protein contributes to the astrocyte swelling leading to brain edema and intracranial pressure in acute liver failure (ALF). However, there is no evidence available to-date to suggest that these alterations occur in patients with ALF. In...
Using waste from palm oil tree is one of the green technology applications. Green product derive from plant will decrease the chemical usage and certified 'halal'. Bio-solid cleaning agent from dodecanoic acid in bio-oil from EPFB was produce, test the properties and compare to commercial cleaning agent. Samples were variation of mole ratios of NaOH to dodecanoic acid. Cold process of fatty acid saponication with alkali was the best method. The dodecanoic acid reacts with NaOH solution at...
Nanoparticles were prepared using chitosan obtained from HI Media Laboratories Pvt, Ltd, Mumbai. The plain haemophilus influenza- b was obtained from Shanta Biotech Pvt. Ltd., Hyderabad, india. The nanoparticle formulation was done by ionotropic gelation technique using chitosan and tripolyphosphate as a cross linking agent. By using the above technique haemophilus influenza was loaded in to chitosan nanoparticles. To study the effect of concentration of polymer on the formation of...
In the last few decades,environmental pollution caused by various hazardous materials especially the heavy metals has been a topic of management and has been monitored closely. Removal of heavy metals from soil and water around industrial plants has been a major challenge. For the removal of theseheavy metals from liquid wastes various methods have been adopted.Some of them includes precipitation,evaporation,membrane process etc.These methods have however several disadvantages like...
Magnesium is the most important and common physiological element in the organism and it also present in the several region of the body. The Mg2+ is second most abundant intracellular cation and the fourth most abundant in the body. It is a very important diagnostic parameter in the medicines. Magnesium is a special properties account for its key roles in the metabolic processes such as transfer, storage, utilization of energy, in the numerous enzymatic, in phosphorylation, genetic information...
INTRODUCTION Yersiniosis or enteric red mouth disease (ERM) is one of the most common and fatal bacterial diseases in salmonid farms, the first isolation of the disease were reported in rainbow trout (Onchorhynchus mikiss) in the USA in the 1950s (Bullock et al., 1978; Rucker, 1966; Tobback et al., 2007). Yersinia is a gram negative coccobacillus, non-spore-forming bacterium that belongs to the Enterobacteriaceae family that often has flagella, actively growing cell are approximately 0.75...
This study examines the relationship between outdoor pollution and health status in Canada. I use data for 143 health regions over the 1997-2008 periods, especially focus on infant and the elderly, combined with four air pollutants. Using ordinary least squares regression models that include year and group fixed effects, the results show that some pollutants have significantly negative impacts on health outcomes, even the current pollution levels are well under the regulatory standards....
