EXPLORING KNOWLEDGE AND SKILLS FOR TOURIST GUIDES: EVIDENCE FROM EGYPT

Tourist Guides, like all employees within the travel (Tourism) industry must be aware of the needs of travelers (Tourists) and adjust their service and products accordingly, to accomplish this goal TGs are expected to process knowledge of guiding. This paper measures the degree of the influence of the area of study and the level of knowledge on experienced TGs through a study conducted on 200 of 6846 the working population of TGs in 2005, licensed to work in the field by the Ministry of Tourism in Egypt. The study used a self-administered questionnaire that revealed important results showing defects in the areas of study and shortage in the knowledge background of the TGs to a certain extend. The conclusion of the study will propose a guiding scheme to develop a certain standard of education and knowledge needed by TGs in Egypt in their drive towards professional recognition, in order to be able to perform effectively in an increasingly competitive field.tour guides (TG), area of study, knowledge background, Egypt

American statecraft for a global digital age: warfare, diplomacy and culture in a segregated world

The aim of this thesis is to investigate how American power is adapting to a changing post- Cold War global landscape. It is commonly accepted that many of the most visible cultural expressions of globalisation are American. However, contemporary accounts have proven inadequate in assessing how such forces have helped provide the infrastructure for America’s global dominance. With growing debate over the decline of American influence, the thesis intends to address how American statecraft is attempting to redefine itself for a digital age. With the accelerated transmission of information, images and sounds, nation-states are gradually losing the ability to either dictate their official narrative or control their global image. The new info-war that lies at the heart of contemporary American statecraft thus involves the wholesale integration of struggles over information, technology, communication and culture into the conflict itself. The thesis, therefore, investigates how American military and diplomatic efforts are both shaping and being reshaped by modern techno-culture. The thesis pieces together a contemporary genealogy of American cultural diplomacy in the Middle East from the Cold War through to the “war on terror”. This genealogy pays particular attention to both the continued hold of civilisationist discourses and the shifting question of race in American foreign policy – from the instrumentalisation of jazz at the height of the ideological antagonism of the Cold War, to rap music as a soundtrack to American Empire. The attention paid to African American culture aims to highlight the ways in which the radical traditions of struggle for freedom from the underside of the American Empire are transforming our world today for both better and worse. The thesis concludes by contextualising the evolving relationship between consumption, technology, communication and (national) security, and situating the Occupied Palestinian Territories within these global capital and cultural flows. This takes the form of an analysis of the multiple local and international socio-economic initiatives taking hold in the West Bank – from governmental institutions and NGOs, to the business sector and consumer industries – and their particular attempts at reshaping Palestinian public spheres

Active substance from some blue green algal species used as antimicrobial agents

The concept of biological control for health maintenance has received widespread attention during the last few years. Therefore, the main objective of this work was to look for active substances that couldbe used as antimicrobial agents in an efficient and safe manner. To achieve this target, five different extracts (ethyl acetate, chloroform, diethyl ether, methanol and water) from three blue green algalspecies (Anabaena flos aquae (Linnaeus) Bory; Anabaena variabilis (Kützing) and Oscillatoria angustissima West and West) were examined. This different algal extracts were tested in vitro for their antimicrobial effects against eight Gram +ve and Gram -ve bacteria in addition to two groups of fungi (filamentous fungi and yeast) using agar well diffusion method. The results showed that the ethyl acetate extract of A. flos aquae notably inhibited nearly the whole tested bacteria and filamentous fungiwith minimal activity against tested yeasts. Furthermore, a significant reduction in sporulation as well as dry weight of the two filamentous fungi was found with ethyl acetate extracts. The toxicity of ethyl acetate extract to Artemia salina showed that the effective concentration that would inhibit their growth by 50% (LC50) after 24 h of incubation was 17, 41 and 45 mg.ml-1 for A. flos aquae, A. variabilis and O. angustissima, respectively. The antagonistic materials from ethyl acetate extract of differentcyanobacterial species were identified using gas liquid chromatography mass spectrometer (GC-MS). The main components of ethyl acetate extract of A. flos aquae consisted of heptadecane and 7-methylheptadecane representing 26.11 and 18.65%, respectively

Antioxidant activity and mineral composition of three Mediterranean common seaweeds from Abu-Qir Bay, Egypt

AbstractAntioxidant activity and mineral composition were evaluated seasonally from spring to autumn 2010 in the three common seaweeds Ulva lactuca Linnaeus (Chlorophyta), Jania rubens (Linnaeus) J.V. Lamouroux and Pterocladia capillacea (S.G. Gmelin) Bornet (Rhodophyta). The antioxidant activity was measured with β-carotene, total phenol content and DPPH (2,2-diphenyl-1-picrylhydrazyl). Seaweeds were collected from the rocky site near Boughaz El-Maadya Abu-Qir Bay of Alexandria, Egypt. The results showed maximum increase of β-carotene in P. capillacea during summer. A significant increase in total phenolic content at P⩽0.05 was found in the red alga (J. rubens) during summer. Also, U. lactuca showed the maximum antioxidant scavenging activity especially during summer. Minerals in all investigated samples were higher than those in conventional edible vegetables. Na/K ratio ranged between 0.78 and 2.4mg/100g, which is a favorable value. All trace metals exceeded the recommended doses by Reference Nutrient Intake (RNI). During summer season, it was found that Cu=2.02±0.13 and Cr=0.46±0.14mg/100g in U. lactuca and Fe had a suitable concentration (18.37±0.5mg/100g) in P. capillacea. The studied species were rich in carotenoids, phenolic compounds, DPPH free radicals and minerals, therefore, they can be used as potential source of health food in human diets and may be of use to food industry

Protective Effects of Flavone from Tamarix aphylla against CCl4-Induced Liver Injury in Mice Mediated by Suppression of Oxidative Stress, Apoptosis and Angiogenesis

The current study aimed to investigate, for the first time, the beneficial effects of 3,5-dihydroxy-4′,7-dimethoxyflavone isolated from Tamarix aphylla L. against liver injury in mice. Liver injury was induced by intraperitoneal (i.p.) injection of carbon tetrachloride (CCl4) at a dose of 0.4 mL/kg mixed in olive oil at ratio (1:4) twice a week for 6 consecutive weeks. The administration of CCl4 caused significant histopathological changes in liver tissues while the pre-treatment with the flavone at dose of 10 and 25 mg/kg ameliorated the observed liver damages. Also, it markedly reduced hepatic malondialdehyde (MDA) level as well as increased the activities of liver superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (Gpx) compared with their recorded levels in CCl4 model group. Moreover, the immunohistochemical analysis demonstrated the enhancement in the protein level of B-cell lymphoma-2 (Bcl-2) while the protein levels of cysteine-aspartic acid protease-3 (caspase-3), Bcl-2-associated x protein (Bax), transforming growth factor-β1 (TGF-β1) and CD31 were suppressed following the flavone treatement. These results suggest that the flavone can inhibit liver injury induced in mice owning to its impact on the oxidation, apoptotic and angiogenesis mechanisms. Further pharmacological investigations are essential to determine the effectiveness of the flavone in human

Sulphatisation and Sulphidisation for hydro-metallurgical extraction of main constituents of a local ilmenite Ore

ILMENITE ores occur in UAR in large quantities, const- ituting two main reserves . The first, estimated to be about 10 million tons, occurs at Abu Ghalaga (AG) in the south-eastern desert, and the second comprises one of the chief constituents of beach placers, called black sands (BS), which are deposited on the shores of the Nile delta, especially at Rosetta and El-Arish. According to previous studies' AG ilmenite occurs in the form of lenticular , vein-like bodies intimately associated with metagabbro. The chief lens is about 300 m long, 150 m wide and 45 to 100 m thick

Modeling of Coastal Processes in the Mediterranean Sea: A Pilot Study on the Entrance of Suez Canal in Egypt

The main objective of this research is applying numerical modeling to simulate the impact of the Suez Canal jetties on the beach morphology and hydrodynamic regime along the Suez Canal coastal zone. In addition, coastal processes including waves and wave-induced currents will be evaluated using 2D modeling. This research will contribute to quantify the shoreline stability during the last three decades. Hydrodynamic and sediment transport (ST) models are utilized to predict sediment transport pathways and how sediment might move within the entrance of Suez Canal port. Remote sensing analyses of the Landsat Thematic Mapper images during 2000–2018 show siltation processes at the entrance of the Suez Canal. Vector analyses of the images’ data indicated updrift accretion at a rate of +15 m/year and downdrift erosion at a rate of −13 m/year. Coastal processes including waves and currents contribute to shoaling problem along the navigation channel of the Suez Canal port. Applications of 2-3D models were used to simulate wave and current dissipation. In addition, beach slope profiles and hydrodynamic models are used to help in understanding the impact of coastal processes on beach morphology and hydrodynamic regime controlling siltation problem along the entrance of Port Said harbor
