Effects Of Bisphenol A And Nicotine On Cytochrome P450s In Brain And Liver Of Pregnant Rats, Mohammad Merii, Manal Fardon, Mahmoud Khalil

BAU Journal - Science and Technology

Bisphenol A (BPA), a widely used chemical, is associated with endocrine disruption through its interactions with the aryl hydrocarbon receptor (AhR). BPA crosses into the human body mostly through migration from plastic packaging into the daily diet. AhR regulates the expression of drug-metabolizing enzymes (DMEs), including numerous CYP450s, and mediates xenobiotic reactions. This study aims at examining how the expression of CYP450s expression is affected, in the brain and liver of pregnant rats, by exposure to BPA and nicotine. Pregnant female Sprague-Dawley dams were exposed to increasing doses of BPA; 0 (control), 50, 500, and 5000 g/kg/day , or in …

Concrete Mix Design Using Abrams And Bolomey Methods, Salem Abdelgader, Marzena Kurpinska, Hakim Abdelgader, Jamal Khatib

BAU Journal - Science and Technology

This research studied concrete design methods. To design concrete using two methods, including the Abrams law and the modified Bolomey method. Concrete with assumed compressive strength 25, 30, 35, 40, and 45 MPa was researched. The research was conducted in the laboratory using two types of samples: cubic 15x15x15cm for compressive strength tests and cylinders ϕ-15cm, h-30cm for the splitting strength tests using the Brazilian method.

The analysis of the cement content in the composition of 1m3 of the mixture showed very large differences depending on the calculation method used. The cement content calculated according to the Abrams method ranged …

Studying Changes And Addressing The Effects Of The Covid-19 Pandemic On Restaurants, Nael Mohamed Nabil Alsarrag

BAU Journal - Creative Sustainable Development

Several everyday activities were majorly affected by the COVID-19 pandemic, adapting these activities to become safe for people to perform and become "covid-friendly" required many studies. Dining out in restaurants was one of the major activities that were affected by this pandemic. Permanently or partially closed, restaurants adapted quickly to sidewalk pickups, and excessive delivery demand, and accordingly, their menus and even the staffing were shortened. Several months later, the foodservice industry was one of the first to move a step forward against coronavirus and positively adapt by coming up with creative and innovative ways to be able to re-open …

Architectural Representations Of Human Rights, El-Bastawissi Y. Ibtihal, Youssef Maged

BAU Journal - Creative Sustainable Development

The United Nations defines the Human Rights as the rights of all human beings, regardless of race, gender, language, religion, nationality, or any other status. These rights include all claims to live freely, to educate and work in equality, and to inhabit humanistic urban and architectural spaces. Throughout the history of architecture, civilisations have generated different perspectives towards respecting the human rights. Temples of Ancient Egyptian Architecture crushed the human scale to introduce religious experiences to their visitors. Tibetan temples over mountains enforced people to make anti-humanistic journeys to reach them. After thousands of years, the mega-scale palaces and cathedrals …

Normality Testing Methods And The Importance Of Skewness And Kurtosis In Statistical Analysis, Georges Hatem, Joe Zeidan, Mathijs Goossens, Carla Moreira

BAU Journal - Science and Technology

The normal distribution (bell curve or Gaussian distribution) is a distribution that happens commonly in many circumstances. Real-life data rarely, if ever, follow a perfect normal distribution. Many tests are useful to test normality and more particularly skewness and kurtosis tests assess the comparability of a given distribution from a normal distribution. These tests are widely used in statistics, business, and epidemiological data including blood pressure, heights, IQ scores and measurement errors. This report provides a review assessing the essential methods employed for testing normality and highlighting the importance of skewness and Kurtosis in statistics. Moreover, it gives some examples …
