Water Harvesting of the area North of Khartoum Bahri

The purpose of this study is to solve the problem of rain water of the area north of the Khartoum Bahri and protect the Villages from the floods, and conduct a comprehensive hydrological study of the water basins passing through that area. The methods used in this study were to collect data from different sources such as Digital Elevation Maps, Urban development maps, Rainfall data. In addition to hydrological, hydro geological studies and survey works. These data were analyzed using hydraulics equations and probability distribution functionsf(x). From the results the basins catchment drainage has been identified and planned based on hydrology, geological and topography of the area and it was found that the basins that produce the torrents, mostly located north east of the catchment, the area of these catchment is 11.5 km 2. The maximum out flow for catchment is about 138 m3/s in the central of catchment area, and is considered the best selected area for the construction of water harvesting technique. Normal distribution has been found to be the best fitted distribution for the representation of the annual rainfall in study area. Conclusion and recommendation drawn from this study is to Construct embankment or dike to prevent the water passing in the north-east direction of the study are

Impact of Augmented Reality on Pattern Designing Using Origami-Style among Clothing and Textile Students

The study aimed to examine the effects of augmented reality technology on the development of origami-style pattern designing skills among female students in the clothing and textile field, as well as to explore their attitudes towards this technology. The quasi-experimental approach was employed to achieve the research objectives, with a sample of 24 female students from the Fourth Grade of the Department of Clothing and Textile, Faculty of Home Economics at Al-Azhar University. The participants were divided into two groups: a control group of 12 students who studied in the traditional way, and an experimental group of 12 students who used augmented reality technology to learn. The study was conducted in the second semester of the academic year 2020/2021. The results showed that there was a statistically significant difference (at a significance level of 0.01) between the average scores of the control group and the experimental group in both cognitive achievement and skill performance, with the experimental group performing better. Additionally, the retention of learned information was higher among the experimental group, and they had a more positive attitude towards using augmented reality technology in learning

Dihydrophenazine:a multifunctional new weapon that kills multidrug-resistant Acinetobacter baumannii and restores carbapenem and oxidative stress susceptibilities

AimsThe current work aims to fully characterize a new antimicrobial agent against Acinetobacter baumannii, which continues to represent a growing threat to healthcare settings worldwide. With minimal treatment options due to the extensive spread of resistance to almost all the available antimicrobials, the hunt for new antimicrobial agents is a high priority. Methods and resultsAn Egyptian soil-derived bacterium strain NHM-077B proved to be a promising source for a new antimicrobial agent. Bioguided fractionation of the culture supernatants of NHM-077B followed by chemical structure elucidation identified the active antimicrobial agent as 1-hydroxy phenazine. Chemical synthesis yielded more derivatives, including dihydrophenazine (DHP), which proved to be the most potent against A. baumannii, yet it exhibited a safe cytotoxicity profile against human skin fibroblasts. Proteomics analysis of the cells treated with DHP revealed multiple proteins with altered expression that could be correlated to the observed phenotypes and potential mechanism of the antimicrobial action of DHP. DHP is a multi-pronged agent that affects membrane integrity, increases susceptibility to oxidative stress, interferes with amino acids/protein synthesis, and modulates virulence-related proteins. Interestingly, DHP in sub-inhibitory concentrations resensitizes the highly virulent carbapenem-resistant A. baumannii strain AB5075 to carbapenems providing great hope in regaining some of the benefits of this important class of antibiotics. ConclusionsThis work underscores the potential of DHP as a promising new agent with multifunctional roles as both a classical and non-conventional antimicrobial agent that is urgently needed.<br/

Longitudinal expression profiling identifies a poor risk subset of patients with ABC-type diffuse large B-cell lymphoma

Despite the effectiveness of immuno-chemotherapy, 40% of patients with diffuse large B-cell lymphoma (DLBCL) experience relapse or refractory disease. Longitudinal studies have previously focused on the mutational landscape of relapse but fell short of providing a consistent relapse-specific genetic signature. In our study, we have focused attention on the changes in GEP accompanying DLBCL relapse using archival paired diagnostic/relapse specimens from 38 de novo patients with DLBCL. COO remained stable from diagnosis to relapse in 80% of patients, with only a single patient showing COO switching from activated B-cell–like (ABC) to germinal center B-cell–like (GCB). Analysis of the transcriptomic changes that occur following relapse suggest ABC and GCB relapses are mediated via different mechanisms. We developed a 30-gene discriminator for ABC–DLBCLs derived from relapse-associated genes that defined clinically distinct high- and low-risk subgroups in ABC–DLBCLs at diagnosis in datasets comprising both population-based and clinical trial cohorts. This signature also identified a population of <60-year–old patients with superior PFS and OS treated with ibrutinib–R-CHOP as part of the PHOENIX trial. Altogether this new signature adds to the existing toolkit of putative genetic predictors now available in DLBCL that can be readily assessed as part of prospective clinical trials

Effect of remote ischaemic conditioning on clinical outcomes in patients with acute myocardial infarction (CONDI-2/ERIC-PPCI): a single-blind randomised controlled trial.

BACKGROUND: Remote ischaemic conditioning with transient ischaemia and reperfusion applied to the arm has been shown to reduce myocardial infarct size in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI). We investigated whether remote ischaemic conditioning could reduce the incidence of cardiac death and hospitalisation for heart failure at 12 months. METHODS: We did an international investigator-initiated, prospective, single-blind, randomised controlled trial (CONDI-2/ERIC-PPCI) at 33 centres across the UK, Denmark, Spain, and Serbia. Patients (age >18 years) with suspected STEMI and who were eligible for PPCI were randomly allocated (1:1, stratified by centre with a permuted block method) to receive standard treatment (including a sham simulated remote ischaemic conditioning intervention at UK sites only) or remote ischaemic conditioning treatment (intermittent ischaemia and reperfusion applied to the arm through four cycles of 5-min inflation and 5-min deflation of an automated cuff device) before PPCI. Investigators responsible for data collection and outcome assessment were masked to treatment allocation. The primary combined endpoint was cardiac death or hospitalisation for heart failure at 12 months in the intention-to-treat population. This trial is registered with ClinicalTrials.gov (NCT02342522) and is completed. FINDINGS: Between Nov 6, 2013, and March 31, 2018, 5401 patients were randomly allocated to either the control group (n=2701) or the remote ischaemic conditioning group (n=2700). After exclusion of patients upon hospital arrival or loss to follow-up, 2569 patients in the control group and 2546 in the intervention group were included in the intention-to-treat analysis. At 12 months post-PPCI, the Kaplan-Meier-estimated frequencies of cardiac death or hospitalisation for heart failure (the primary endpoint) were 220 (8·6%) patients in the control group and 239 (9·4%) in the remote ischaemic conditioning group (hazard ratio 1·10 [95% CI 0·91-1·32], p=0·32 for intervention versus control). No important unexpected adverse events or side effects of remote ischaemic conditioning were observed. INTERPRETATION: Remote ischaemic conditioning does not improve clinical outcomes (cardiac death or hospitalisation for heart failure) at 12 months in patients with STEMI undergoing PPCI.

A maximum antibacterial activity was observed by the Glacial acetic acid extract of Striga hermonthica while the ethanol extract of whole plant reflected moderate activity. All extracts showed no activity against all fungal strains tested. The ethanol extract of Nigella sativa seeds showed a moderate activity against bacteria strains tested

Interrelationships between Yield and it Components in some Roselle (Hibiscus Sabdariffa L.) Genotypes

Abstract Sixteen genotypes of Roselle (Hibiscus sabdariffa L.) were evaluated for two seasons to estimate phenotypic and genotypic correlations, path analysis and selection indices. They study was conducted at Shambat Demonstration Farm in a randomized complete block design with three replications. Data were collected on thirteen plant attributes. Number of capsules/branch, 1000-seed weight, fruit yield /plant, seed yield/plant and calyx yield /unit area exhibited significant positive genotypic correlations with calyx yield/plant in the second season. On the other hand, the plant height, number of fruiting branches/plant, fruit weight, mean calyx weight/capsule, seed yield/plant and calyx yield/unit area showed significant negative genotypic correlations with calyx yield per plant in the first season. At the phenotypic level, calyx yield per plant had positive and significant association with number of capsules/main stem, number of capsules/branch, fruit yield/plant and seed yield/plant in both seasons. The yield components showed different patterns of association with each other. The path analysis indicated that fruit weight had the highest direct effect (0.46) on calyx yield/plant, while fruit yield had the lowest one (-0.19). The selection index based on number of fruiting branches/plant alone produced the highest expected genetic advance (1.66|) and the highest relative efficiency (40.39), followed by number of capsules/main stem and fruit weight. On the other hand, fruit yield/plant produced the lowest expected genetic advance (0.41) and lowest relative efficiency (9.98). Consequently, number of fruiting branches/plant, number of capsules/main stem and fruit weight can be used as selection criteria for the improvement of calyx yield/plant in Roselle
