Cost-Efficient Storage for On-Demand Video Streaming on Cloud

Video stream is converted to several formats to support the user's device, this conversion process is called video transcoding, which imposes high storage and powerful resources. With emerging of cloud technology, video stream companies adopted to process video on the cloud. Generally, many formats of the same video are made (pre-transcoded) and streamed to the adequate user's device. However, pre-transcoding demands huge storage space and incurs a high-cost to the video stream companies. More importantly, the pre-transcoding of video streams could be hierarchy carried out through different storage types in the cloud. To minimize the storage cost, in this paper, we propose a method to store video streams in the hierarchical storage of the cloud. Particularly, we develop a method to decide which video stream should be pre-transcoded in its suitable cloud storage to minimize the overall cost. Experimental simulation and results show the effectiveness of our approach, specifically, when the percentage of frequently accessed videos is high in repositories, the proposed approach minimizes the overall cost by up to 40 percent.Comment: International IEEE World Forum for Internet of Thing

Detection of HER-2/neu, c-myc amplification and p53 inactivation by FISH in Egyptian patients with breast cancer

Breast cancer is a leading cause of cancer-related deaths in women worldwide. The clinical course of this disease is highly variable and clinicians continuously search for prognostic parameters that can accurately predict prognosis, and indicate a suitable adjuvant therapy for each patient. Amplification of the two oncogenes HER-2/neu and c-myc and inactivation of the tumor suppressor gene p53 are frequently encountered in breast carcinomas. The purpose of this study was to use the fluorescence in situ hybridization (FISH) for the assessment of HER-2/neu and c-myc amplification and p53 inactivation and to relate these molecular markers with the commonly used clinical and pathological factors. The study was conducted on 34 tissue samples obtained from 33 females and 1 male with breast carcinomas and 17 samples obtained from 16 females and 1 male with benign breast lesions. Results revealed that the level of HER-2/neu, c-myc and p53 in the malignant group was significantly increased as compared to the benign group. On relating the level of the molecular markers to clinicopathological factors, p53 was significantly associated with increased patient’s age. The sensitivity of the investigated markers significantly increased with larger tumor size. Concerning tumor grade, HER-2/neu and p53 showed a significant increase in low-grade tumors whereas c-myc showed a highly significant increase in high-grade tumors. With regard to disease staging, HER-2/neu and c-myc were the only markers that showed significant increase at late stages of disease. p53 and HER-2/neu were significantly associated with positive lymph nodal status. A significant correlation was obtained between the levels of the three biomarkers to each other. Conclusively, the combination of HER-2/neu, c-myc and p53 can stratify patients into different risk groups

Effect of Focused Shock Wave Therapy on Pain and Elbow Heterotopic Ossification Following Burns.

Background: Burns are devastating injuries, often resulting in significant morbidity, impairment of emotional well-being, and experienced quality of life. Objective: to evaluate the effect of focused shock wave therapy on pain and elbow heterotopic ossification following burns. Methods: Forty patients with elbow heterotopic ossification following burns participated in this study, they were selected from Kasr El-Aini (Cairo University hospitals and OM El-¬Masrieen hospitals (Ministry of Health). The patients were randomly assigned into two equal groups, 20 patients for each group. Group A (study Group) included twenty patients with elbow pain and heterotopic ossification following burns and they received both Focused Extracorporeal shockwave therapy plus the routine medical care (Etidronate, 300mg, twice a day, for 7 weeks). while group B (control Group) received only the routine medical care. Treatment consisted of 7 brief, non-invasive sessions given over 7 weeks, Each EWST treatment consisted of 3500 pulses at 4 Hz with an energy flux density in the range of 0.03 to 0.36 mJ/mm2. Evaluation for all patients was done before and after the treatment using Visual analogue scale (VAS) and Computed Tomography Scan (CTS) according to the Della Valle classification system. Results: there was highly significant reduction in VAS but in spite of the occurrence of improvement in some cases of the second records of CTS in grades in the ESWT group, there was non-significant difference from the statistical point of view, between both groups. Conclusion: The application of the focused shock wave therapy on pain and elbow heterotopic ossification following burns had only a minimal effect on some of the patien

Anxiety and Depression among Family Caregivers of Older Adults with Cancer

Anxiety and depression are the most common problems experienced by family caregivers. Aim: to assess anxiety and depression among family caregivers of older adults with cancer. Method: descriptive research design was used in this study. The study carried out on 157 family caregivers of the older adults diagnosed with cancer attending Mansoura Oncology Center within a period of three months. Data was collected using four tools, Socio demographic and clinical data structured interview schedule, Barthel Index Scale, Lawton and Brody Scale and Hospital Anxiety and Depression Scale. Results: the mean scores of anxiety were 11.31±3.37 in which the prevalence of anxiety among caregivers was 85.3%. The mean scores of depression were 10.64±3.22 in which the prevalence of depression was 81.5%. Conclusion: Family caregivers of older adults with cancer experienced high levels of anxiety and depression. Keywords: Older adults, Cancer, Anxiety, Depression, Family caregiver

BIOLOGICAL CONTROL OF SOIL -BORNE FUNGAL PATHOGENS

Seventeen bacterial isolates have been successfully isolated and purified from soil rhizosphere samples collected from different agricultural areas Buhayra, Sharqia and Alqilyubia of Egypt, and screened for production of chitinase enzymes had the highest chitinolytic activities amongst those investigated. Isolate S3-C and S1-C were Identified by biochemical, physiological tests and 16s rRNA gene primer as Bacillus cereus S3C, Gene Bank NCBI accession MK185696 and Bacillus cereus S1C accession MK185697. The production of chitinase by B.cereus S3C and Bacillus cereus S1C was optimized using colloidal chitin medium amended with 1% colloidal chitin at 30°C after five days of incubation. B.cereus S3C had potential for cell wall lysis of many phytopathogenic fungi tested such as Fusarium oxysporum and Rhizoctonia solani Potato phytopathogenic fungi by in vitro antagonistic test. The addition of B. cereus S3C chitinase was more effective than that of B.cereus S1C in increasing the resistance of Potato plants infected with various Soil- borne phytopathogenic fungi

The Impact of Leverage on Stock Earnings: The Case of the Abu Dhabi Stock Market

This study investigates the relationship between leverage and stock earnings in the Abu Dhabi stock market from 2006 to 2015, employing a time series computed tomography (CT) scan methodology. The dependent variable, earnings per share (EPS), is analyzed concerning various leverage ratios, including the Debt-to-Assets Ratio (DA), Debt-to-Property Ratio (DP), Long-Term Debt-to-Assets Ratio (LDA), and Long-Term Debt-to-Property Rights Ratio (LDP). Our findings reveal a positive effect of the DP ratio on leverage, while a negative impact is evident with the LDP ratio. Through a static analysis model, the study elucidates the short-run effects of leverage on earnings, characterized by the ratio of total debt to ownership using autoregression vectors. These insights enhance our understanding of the intricate relationship between leverage and stock earnings in the Abu Dhabi stock market
