Cloud computing ecosystem is one of the trends currently being discussed in the domain of information technology and computing. Computing ecosystem allows smart usage of technology which means unneeded resources are saved such as power, computing resources, spaces for datacenters as well as saving huge amount of CO2 and electric circuit boards and machines. Cloud federation and its underlying techniques, is considered role model in sharing and expanding cloud business to provide better and cheaper services for end-users. In this thesis, we will survey and compare existing Identity Access Management ...

Purpose: With the rapid increase in respiratory illnesses and pollution, face masks such as clothe masks, N95 masks, and surgical masks are becoming increasingly more common in everyday life. The recent SARS-CoV-2 outbreak has led to the exponential worldwide use of these masks in everyday activities. However, little is known about the effects of these masks on maximal oxygen consumption during exhaustive exercise. Methods: 11 Athletic individuals and 7 recreational individuals were recruited and took part in the 20 m shuttle run test, also known as the “beep test”, while wearing surgical masks ...

The purpose of this thesis is to study distributed applications in the context of heterogeneous clients (Web browser, mobile) and business-to-business (B2B) integration. Two distributed architectures, leaders of the distributed applications market are presented and compared: Microsoft's .NET, and Sun's Java Enterprise Java Beans (J2EE). After this comparative study, we chose .NET to develop an e- commerce application (Jurasco Style electronic shop) in order to outline the major application architectural issues and solutions offered by .NET technology. Our study also shows how the .NET Jurasco ...

Eggs are one of nature’s most nutritious and economical foods. Besides their nutritional value, antioxidant, anti‐cancerous, antihypertensive activity, and immunomodulatory effects, chemical and microbial contamination of eggs pose a risk on human health. Chemical contamination is due to the abuse of antibiotics in poultry. Microbial contamination can be through horizontal or vertical transmission. Microbial contamination accompanies a high risk of spread of antibiotic resistance. Microbial contamination can be controlled by choosing the egg source wisely and by storing eggs carefully. A lot of ...

Humans are exposed to a notable variety of toxicants including lead as a heavy metal resulting from occupations and through environmental accumulation as in the Lebanese coastal and freshwaters. It is well established that lead exposure in the workplace contributes to worker infertility and decreased reproductive efficiency. Several reports have reported the detrimental impact toxic effects on human male reproduction by subsiding libido, spermatogenesis, semen quality, hormonal production and regulation, and much more. The objectives of this study were to inspect the effects of ...

During recent years, the practice of administering antibiotics to animal feed at sub-therapeutic levels has raised concern with consumers because of the apparent increase of antibiotic-resistant bacteria in the human food chain. Researchers have found that probiotics composed of naturally occurring beneficial live microbes such as bacteria (lactobacilli) could be the novel growth promoters. Supplementing poultry diet with probiotics has been found to improve growth performance, feed conversion efficiency, and immune responses, and help in combating enteric pathogens. The aim of this study is ...

Software components enable practical reuse of software parts and amortization of investments over multiple applications. Software components are binary units of independent production, acquisition that are combined together to form a functioning system. Building solution by combining bought and made components improves quality and supports rapid development, leading to short time to market. For these reasons, component technology is expected by many to be the corner stone of software in the year to come. Even though component software is a very promising way of building applications, it is very ...

Low-Ionization Nuclear Emission-Line Regions (LINERs) represent the low luminosity end of Active Galactic Nuclei (AGN). The main power source of LINERs is the subject of considerable debate in the scientific community today, despite the fact that some Liners show features of mass accretion into a super massive black hole (SMBH). Optical line-ratio diagrams are not conclusive diagnostic tools as they can be explained by different mechanisms, including shocks (Dopita et al. 1997[8]) and photoionization accompanied by outflow resembling accretion (Sabra et al. 2003[23]). This dissertation will ...

This thesis uses the link structure of the World Wide Web as a basis to create better search engines. It focuses on the HITS algorithm, which was the first algorithm to up the link topology. HITS is implemented with slight modifications and tested with variations of its input parameters. It is also used in order to discover emerging communities in cyberspace. Other related algorithms, which use the link structure of the web as an undirected graph are described and compared with HITS. Finally, an attempt to combine link-based with text-based analysis in order to create more accurate search methods ...

The HPG axis interacts with the Sertoli and Leydig cells to ensure the proper functioning of the male reproductive system. Environmental insults, which are becoming increasingly more common, affect the sensitive male reproductive system in harmful ways. Therefore, the aim of this thesis was to, analyze a network of the paternally imprinted infertility genes shared between the HPG axis and the Sertoli and Leydig cells. With this network in place, we aimed to develop a cell culture system that would allow the evaluation of the effects of certain environmental contaminants such as mycotoxins on ...
