Antibacterial Effect And Phytochemical Analysis Of The Shoot System Of Rubus Canescens Dc. Growing In Lebanon, Omar Assafiri, Hiba Abdallah, Mohammed El-Dakdouki

BAU Journal - Science and Technology

The misuse of antibiotics followed by improved fitness of resistant strains of infectious microorganisms hindered the efficacy of many known antimicrobial agents, and fueled research for the discovery of novel remedies. The current study aims at assessing the antimicrobial activity and understanding the mechanism of action of Rubus canescens DC. growing wild in Lebanon, as well as qualitatively determining its phytochemical profile. The antibacterial activity, MIC, and MBC of the extracts were evaluated by two-fold dilution. Time-kill curves were plotted to assess the bactericidal activity of the R. canescens DC. extracts against the growth of microorganisms, and TEM images were …

Waterpipe: A Global Alarming Problem, Tarek Houri, Bilal Osta, Sara Mobayed, Rayan Farha, Mazher Issa

BAU Journal - Science and Technology

Waterpipe popularity has increased significantly in the recent decades to become the major cause of death worldwide. This practice, which is also known as hookah, shisha and Narghile that is based on tobacco burning, increases the percentage of tobacco smokers especially among young people, due to several factors such as the attracting effect of sweetened tobacco, the marketing role and the social acceptance of waterpipe. A literature review was constructed using "Pub med" as a searching tool to confirm by studies the differences in adverse effects between waterpipe and cigarette by analyzing the toxicant’s levels generated from them, evaluating the …

Corrosion Of Coated And Uncoated Steel Reinforcement In Concrete, Jana Abou Shakra, Rouba Joumblat, Jamal Khatib, Adel Elkordi

BAU Journal - Science and Technology

Corrosion of reinforcing steel is the one of the main causes of deterioration in reinforced concrete structure. During the initial stage of corrosion, the steel volume increases. This creates tensile stresses in the concrete, which can eventually lead to cracking, delamination, and spalling. This potential risk of corrosion in a structure is quite unpredictable. Therefore, this paper examines the influence of accelerated corrosion on the bond between concrete and the coated and uncoated steel bars. The bar coating consisted of epoxy rich in zinc. Six concrete mixes were prepared. Three mixes had cement contents of 300, 400 and 500 Kg/m3 …

Effect Of Using Cathode-Ray Tubes (Crt) Waste Glass On Concrete Properties, Jad Bawab, Jamal Khatib, Ali Jahami, Said Kenai, Adel Elkordi

BAU Journal - Science and Technology

Cathode-ray tube (CRT) glass is a hazardous material that should be responsibly managed when disposed. One of the possible options for recycling CRT waste glass is using it as fine aggregates in concrete for its richness in silica. For the aim of evaluating concrete with this material, four mixes with replacement levels of 0%, 10%, 20% and 30% are prepared. Workability, hardened density, ultra-pulse velocity, compressive strength, tensile strength, and static modulus of elasticity were examined. Experimental results showed that the use of CRT improved properties of concrete at certain replacement levels. CRT glass improved the workability of concrete where …

Concrete Mix Design Using Simple Equations, Hakim Abdelgader, Ramadan Suleiman, Abdalla Adam, Jamal Khatib

BAU Journal - Science and Technology

The behaviour of concrete, whether fresh or hardened, depends basically on the behaviour of its components and the relationship between them, therefore, obtaining a concrete with certain properties depends fundamentally on the concrete mix design. Concrete mix design generally includes two main steps: 1-Selection of the main components suitable for the concrete (cement, aggregate, water, and additives); 2-Determination of more economical mix ratios to fulfil the workability, strength and efficiency requirements. Currently, there are many international methods locally approved for mix designs. They are all related to each other, they give relatively the same quantities of the mix components and …

Essential Control To Environmental Regulations For Oil And Gas Industry: Spotlight On Drilling Processes In Lebanon, Rami Harkouss

BAU Journal - Science and Technology

At present, environmental legislation bounds the drilling operators in drilling wastes removal. The rapid increasing sensitivity of drilling waste management forced many countries to develop environmental guidelines for their drilling operations. This research studies some sorts of waste produced during upstream petroleum activities, particularly while drilling. After that, many hazards and impacts on the environment are addressed, as well as their principal treatment techniques. This paper gives a modest and theoretical vision over the present environmental standard and waste management design, realized at a universal scale. Studies show that performance fluid management and total fluid management are highly recommended in …

Language Change To Enhance Health And Well-Being:A Sociolinguistic Approach, Laila C.A. Helmi Associate Professor, Department Of English, Faculty Of Human Sciences

BAU Journal - Health and Wellbeing

There is no doubt that language change is strongly related to social change, and this is always associated with an essential change in the socio-cultural meaning adopted by the relevant speech-community. It is also a fact that a speechcommunity’s perception of a concept or a phenomenon depends largely on their linguistic encoding thereof, i.e. the lexicalization and/or grammaticalization of the concept. When a social institution, therefore, seeks to influence the community’s conception and behavior, it becomes essential to introduce relevant changes in the language used by the community. If such process does not follow adequate language planning policies and mechanisms, …

Hypertension Among Refugees: A Disease Of Risingpublic Health Concern, Issam Shaarani Senior Lecturer Of Family Medicine, Department Of Clinical Sciences, Faculty Of Medicine,, Rami Warrak

BAU Journal - Health and Wellbeing

After the war in Syria, Lebanon became among the top countries hosting for refugees. Many public health issues started to be raised with non-communicable diseases (NCDs) being high on the list. Providing health care for refugees is not easy since it requires huge resources, continuous follow-up encounters, and an extensive financial support. Reports show that NCDs are a health priority in Syrian refugees, and hypertension is the most prevalent one affecting more than half of the older Syrian refugees in Lebanon. This creates an enormous burden on the host community health system that needs effective interventions. While Lebanese citizens favor …
