Restaurants use storytelling to emotionally connect with customers, highlight their strengths, preserve their great image, and reinforce their strengths while minimizing their weaknesses. For achieving the research aim, an electronic questionnaire was designed and distributed to a random sample of customers in Egyptian restaurants. Participants received information to examine the effects of storytelling and to evaluate their purchasing intentions towards restaurant stories using a five-point Likert scale, which 396 responses were received and valid to analyze by SPSS V.25. Results indicated that investigated customers have sufficient awareness of restaurant storytelling. With regard to analyze customers' intentions towards storytelling, the majority of customers are aware of storytelling concept and intend to go to a restaurant that uses this perspective, which the average of respondents' answers was agree in some statements. Based on the results, some recommendations have been proposed, "Training employees on how to use the marketing storytelling perspective" and also It is recommended that the restaurant management be hired in officials or marketing personnel who have sufficient experience with the concept of storytelling.

Multi-tenancy architecture allows SaaS providers to run a single application and a database instance, which support multiple tenants with various business needs and priorities. Until now, the database management systems (DBMSs) have not had the notion of multi-tenancy, and they have

Current grid schedulers suffer from the haste problem, which is the inability to schedule all tasks successfully. Accordingly, some tasks fail to complete execution as they are allocated to unsuitable workers. Others may not start execution as suitable workers are previously allocated to other tasks. This paper introduces the scheduling haste problem and presents a novel high throughput grid scheduler. The proposed scheduler selects the most suitable worker to execute an input grid task. Hence, it minimizes the turnaround time for a set of grid tasks. Moreover, the scheduler is system oriented and avoids the scheduling haste problem. Experimental results show that the proposed scheduler outperforms traditional grid schedulers as it introduces better scheduling efficiency.

Optical, secondary and transmission electron microscopy found that a majority of as cold-rolled grains contain a large fraction of primary twin densities and a smaller fraction of secondary twins. Partially recrystallised microstructures comprise a mix of recrystallised grains and annealing twins as

Current semantic Web service research focuses on defining models and languages for the semantic markup of all relevant aspects of services, which are accessible through a Web service interface. The Web service modelling ontology (WSMO) is one of the most significant semantic Web service framework proposed to date. To support ...

Samples (1 ml) were inoculated into MacConkey broth (MB, 9 ml) and incubated at 37°C for 24 h, after which a loopful of the MB was then spread onto Eosin Methylene Blue (EMB) and further incubated for 24 h at 37°C in order to isolate E. coli. The identification of isolates was done using standard biochemical procedures; and confirmed serologically using E. coli polyvalent antisera (Bioweb, SA). Isolates were also characterized for virulence factors such as verotoxin, haemolysin, gelatinase, extended spectrum beta lactamases (ESBLs), cell surface hydrophobicity and bacterial serum resistance, as well as susceptibility (using disc diffusion method) to stem bark extracts of Curtisia dentata. Results showed the presence of different serotypes of E. coli (69 isolates in all) including 026: H11, 055, O111: NM, O126, O44, O124, O96:H9, O103:H2, O145: NM and O145:H2. Over 60% of the isolates exhibited serum resistance, haemolysin and gelatinase production, 81% exhibited cell surface hydrophobicity and over 52% produced ESBLs. Results also showed that while 60% of the isolates showed various levels of resistance to different antibiotics [ampicillin (10 µg), cefuroxime, cephalexin, ceftazidime and tetracycline (30 µg in each case) (multidrug resistance index (MDRI) values 4.20 to 5.60%)], only 28% were resistant to ethanol stem bark extracts of C. dentata (MIC, 70 to 150 mg/ml). The presence of pathogenic verotoxic antibiotic resistant E. coli in these water sources is a threat to water quality and food security and C. dentata has a potential for sourcing novel antibiotic substances for chemotherapy against these resistant pathogenic strains of E. coli.
