Numerical Computation of Natural Ventilation System at Different Floor for A Multistory Building[ ]


Dhaka city of Bangladesh has its humble start as a city in 17th century, after the emergence of independent Bangladesh in1971. Natural ventilation system at different floor of a eight storied building is discussed in this study numerically. Mass flow analysis are discussed using velocity vector, and velocity contour. The k - e turbulence model is used for the computation of nature of the air flow at different height. ANSYS CFX software is used to solve the governing equations. Model is also validated by comparing the result with an experimental result published previously. Bangladesh national building code is applied for modeling the building. Ventilation rate for acceptable indoor air quality is assured by comparing the result with ANSI/ASHRAE Standard 62.1-2004.

A REVIEW ON AROMATASE INHIBITORS FOR BREAST CANCER[ ]


Breast cancer is cancer that forms in the calls of the cells of the breasts. After skin cancer, breast cancer is the most common cancer diagnosed in women in the United States. Breast cancer can occur in both men and women, but it’s far more in women. Aromatase inhibitors are the selective therapy for breast cancer Aromatase inhibitors are an anti-estrogen agent that targets specifically the aromatase enzyme. Aromatase, also called estrogen synthetase or estrogen synthase is an enzyme responsible for a key step in the biosynthesis of estrogen. It is CYP19A1, a member of the cytochrome p450 superfamily. Aromatase is responsible for the aromatization of androgen into estrogen.

A Conceptual Underwater Diving System for Pipeline Repairs in Nigerian Muddy Water Niger Delta Oil and Gas Locations[ ]


Inspection and repair of leaking underwater pipeline in muddy water is generally difficult to perform in line with relevant engineering and construction standards. This is basically due to the requirement to closely and visually inspect the problem and then developing best strategy to fix it. It is therefore obvious that when the problem or the leak area or location is inadequately examined due to muddiness of the water mass, strategizing for repair becomes a trial and error operation.

Economic valuation on water and property rights using direct marked approach[ ]


Since farmers lack the knowledge on how environmental factor like water and socioeconomic factor like property right affect their rice production in terms of a monitory value, valuation of water and property rights is practiced in this paper using direct market approach where values can be obtained using the price of rice sold in the market. In association to the valuation, effect to the rice production when both environmental and socioeconomic factor (water and property right respectively) mixed together is also seen in this paper as no one has done research over this topic. In this paper, there are four objectives; to estimate the association between water and rice yield, to estimate the association between property right and rice yield, to evaluate if the effect of water discharge is heterogeneous between different property rights and to find the economic value of water and property rights.

Impact of Global pandemic on the consumer buying behavior: live or Die[ ]


The global pandemic, lockdown, and social distancing mandates have disrupted both the consumer's buying and shopping tastes. Consumers are learning to improvise and to learn new tastes. Consumers cannot go to the supermarket, so the store comes home. Although consumers are moving back to old tastes, it is possible that new rules and practices in the way consumers shop and buy goods and services will be changed by the government. As all elements of the economy are intricately interlinked with public health initiatives and lock-ups, this has resulted in the nation's economic turmoil hinting at a shift in market dynamics.

Computational prediction of PTM in Biologics[ ]


Biopharmaceuticals, also known as biologics, are products manufactured from biological sources and used to diagnose and treat diseases. It consists of vaccines, gene therapies, medicinal protein hormones, monoclonal antibodies, and growth factors. A majority of them are in-tricate mixtures that are not readily known or distinguished and are highly sensitive to their manufacturing and handling conditions. These are often made by genetically modifying cell constituents or cell lines, requiring stable conditions to remain sturdy and intact, which require enormous cost and resources. Even minor alterations lead to cell behavior changes and differences in the structure, stability, or other quali-ty features of the end product. This kind of product has enormous therapeutic potential.
