    Get PDF
    One of the major issues facing the world, particularly developing countries, is waste management. “Waste” is any material that is not needed or has no intended use. Neglecting this waste endangers the safety of the public and causes harm, as it emits dangerous gases that have negative effects on human health. Egypt has made distinguished efforts to achieve the goals of Egypt Vision 2030 and the Sustainable Development Goals. These efforts, which have been implemented through massive government projects throughout the past few years and are set to be followed by more in the future, still require a lot of effort to achieve the waste management mission. There are many different sources of waste, including municipal, industrial, medical, construction, electronic, and agricultural waste. The major goal of this study is to provide an in-depth analysis and identify research methodologies for waste management and classification employing artificial intelligence

    The decisions of the Alexandria Local Authorities would be a key motive power of the flourishing process in Alexandria City Center as a retailing center. The objective of this study is to pay more attention toward re-thinking "Emotionally" to identify any planning policies at various levels. This new tendency would be helpful for having a prosperous city center, after losing its significance as a retailing center. This degradation due to the presence of "Malls and Plazas" like 'City Center Mall," "Green Plaza," and "Down Town Plaza" lying on the peripheral of the city as well as many other reasons. Studying the Saad Zaghloul Street is part of this paper to prove that re-thinking "Emotionally" is the answer to the enhancement Alexandria City Center as a retailing center

    A Business Analysis Perspective for Engineering Education in Egypt

    This work examines engineering education in Egypt provided by state (government funded) universities. There have been concerns from all stakeholders about the graduates’ knowledge and skills. The chronic problems with higher education in Egypt in general have been previously reported in the Literature, but this paper provides insights form engineering academics with many years of experience in Egyptian engineering education and a fresh look from a business perspective at the phenomenon. In this manuscript, the institutions are analyzed using the integrated business anatomy model, in order to identify the underlying causes of the problems observed. The structural, operational and environmental (both external and internal) challenges that lead to the current status are clearly detected. The analysis highlighted several constraints that hinder radical reforms. Amongst these constraints is the legal and organizational framework in which the state funded universities operate. Other social, technological and economic factors also play important parts. The recipe for improvement provided by the authors has taken all these elements into consideration. This work hopes to provide focus and direction for future reform efforts

    Effect of micro TiOâ‚‚ on cement mortar

    TiO2 is a primary photocatalytic ingredient. If incorporated into building materials, it can keep surfaces clean and significantly reduce smog-forming air pollutants. Many researchers have focused on the ability of Nano TiO2 to reduce NOx emissions or other pollutants. However, developing countries are unable to widely utilize Nano materials due to cost and technology barriers, in spite of their great need to find means for protecting structures from pollution and improve air quality. Some studies proved that micro TiO2 (commercial grade) also has photocatalytic properties. However, the effect of this inclusion on key mechanical and durability properties needs to be verified before being recommended for wide use. In this research the effect of commercial grade TiO2 powder on fresh state flow, compressive strength, shrinkage, sulfate resistance and carbonation. The results indicated that TiO2 decreased the workability as mortars became more sticky and dry with increased TiO2 content. The compressive strength was also reduced in TiO2 containing samples compared to the control samples especially at early ages .However, TiO2 powder as an additive in mortar was useful in reducing carbonation due to the filler effect. No samples in the current investigation showed signs of cracking or expansive mass loss due to sulfate exposure. It is recommended that TiO2 powder should be used as an additive to the mortar plaster to help in controlling the air pollution problem. However, some mix adjustment may be needed to counteract the loss in flow and strength due to the inclusion of TiO2 powder

    This article is a modest reflection on identity issues in The gone of chaâba and its film adaptation. A large space will be devoted to writing strategies adopted by Azouz Begag to represent complex issues such as the identity, the otherness and the gaze of the Other. From the migratory phenomenon, racism, marginality, wandering of the first generation, we pass to the rejection of the enslavement, to the challenge and the engagement of the children coming from the second generation of the immigration

    Reshaping the Urban Experience: Prospects for Digital Streetscape towards better Livability in Public Spaces

    Get PDF
    As addressed through the literature on urban planning and design, urban livability concepts generally focus on the issue of “quality of life”. Streetscape design is a good tool that can be used to create a sense of place and improve the urban quality. Thus, streetscape design and urban livability are strongly interconnected. But this connection needs desirable and attractive urban spaces that could interpret and reflect its richness. However, urban spaces are now exclusive domain managed almost entirely for traffic flow which makes them lose their distinctive character as places for people. Furthermore, with the continuous growth of internet usage, people’s needs of public spaces have differed. These needs have to be specified. New possibilities of use and new atmospheres should be also created to cope with their new needs. Therefore, cities around the world are progressively working on developing new strategies to face the 21st century’s challenges. In this context, the paper raises the question of how urban spaces can be enhanced, depending on streetscape’s improvements, to promote livability for its users. Based on the fundamental idea that streets are places for people more than just being arteries for traffic, the paper proposes the “Digital Streetscape” concept as a hybrid model that correlates the advantages of three techniques to meet the contemporary needs of people as well as to rejuvenate cities. On a broader level, the paper aims to conclude a set of guidelines and recommendations to improve the main elements of streetscape design that are derived from the theoretical study. This is carried out to identify the most suitable design concepts and options that can be adopted in the design of future urban spaces to produce new generation of livable communities

    The present study was aimed to investigate the potential protective effect of aqueous extracts of the flesh of dates (Phoenix dactylifera L.) against amitraz-induced infertility in male rats.  100 male Sprague-Dawley rats (120-150 g) were used. The animals were randomly divided into 4 groups  as follows:  Group 1, control animals were given free access to food and water, group 2 received dates extract (1/10 w/v) , group 3   received 1/20 of LD50 amitraz and group 4 received dates extract and the same dose of amitraz as in group 3. Infertility was investigated by examining sperm count, viability, and motility. Estimated levels of testosterone, estradiol and histopathological analysis were also done. The present results showed significant decrease in sperms count,  motility and viability in  group III rats that received  amitraz (P<0.001), increased  percentage of sperm cell abnormalities and decreased serum estradiol and testosterone hormones to 49.8+3.2 and 1.5±0.20 ng/dL versus 56.7+2.4 and 3.3 ±0.37 ng/dL respectively  compared with control. Histopathological examination of the testes also showed marked degeneration of spermatogenic cells associated with interstitial necrosis and blood vessel congestion. Spermatogenic cells and cellular debris were present in the seminiferous tubules lumen associated with moderate degeneration of spermatogenic cells lining of some seminiferous tubules with interstitial diffuse edema. The current results documented that date palm fruit extract possessed an anti-oxidant and anti-infertility effect. We concluded  that amitraz-induced testis damage in rats can be ameliorated by administration of date palm fruit extract. Keywords: Amitraz, dates palm, testis, testosterone, infertility
