Pseudomonas aeruginosa is an aerobic, non-fermentative, gram negative Bacillus belongs to the family Pseudomonadaceae. It is also a non-sporing, motile with polar flagellum, and straight or slightly curved rod-shaped bacterium that occurs as a single bacterium or in pairs and occasionally in short chains. Its antibiotic resistance to various drugs is of a major clinical importance. A total of fifteen (15) samples were collected individually from the various ward at Chukwuemeka Odummewu Ojukwu University Teaching Hospital, Amaku, Awka, (COOUTH) using sterile swab sticks. The swab samples collected were properly labeled as sample 1 to sample 15and were analyzed at Microbiology Laboratory of Nnamdi Azikiwe.........

A cryptocurrency is a sort of digital OR virtual money generated using encryption methods, in which records are preserved and transactions are authenticated by a decentralized system using encryption rather than a central authority. Cryptography is used to secure transactions in cryptocurrency. The first cryptocurrency was created in 2009 and is still the most well-known today: Bitcoin. Investing in cryptocurrencies for financial gain is a major draw. Apart from Bitcoin, there are multiple other cryptocurrencies like Ethereum, Litecoin, Ripple, Steller, Coinbase etc in the financial world. In 2023 and beyond, cryptocurrencies have the potential to drastically change how we utilize money......

The aim of this work is to carry out a comparative study between the falling film absorber, trays and packed absorber columns applied to the absorption refrigeration system using the mixture of ammonia and water as the working fluid. For this comparison, the concentration of ammonia in the liquid phase at the outlet of the absorbers was used as the design variable. In order to carry out this study, simulations of the tray and packed absorber columns were carried out using the Aspen Plus commercial simulator. The simulations of the falling film absorber were carried out in Matlab, as Aspen Plus does not have a model for this equipment in its operating packages........

Road over bridges (ROB) frequently use tied arch bridges with vertical hangers. Hanger spacing and arrangement has greater influence in the structural behaviour of tied arch bridges. A network hanger arrangement is a set of slanted hangers used in tied arch bridges. In this study a parametric study was conducted on different network profiles and the behaviour of arch was investigated considering Hanger's inclination, number, and reduction in bending moment and axial force, and Hanger's relaxation in Network arch bridges. The variations in structural forces for different profiles are discussed in detail, and it was observed that network profile with radial hangers is efficient for IRC live loads. This study is aimed to give an insight and confidence to the bridge designers and structural engineering fraternity for adopting network arch bridges for road over bridges (ROB) in India.

Author Keywords:- Network arches, Cable profile, Slanted hangers, ROB's.
