Creative Thinking and its Relation to Social Status among the High School Students in Jerusalem
This research aims at investigating the relationship between creative thinking and social status among high school students in Jerusalem. A developed version of Torrance Scale of Creative Thinking and a developed scale for social status were implemented. The study sample consisted of 250 secondary stage students. The descriptive approach was used to achieve the study goals. The results revealed that the level of creative thinking among high school students in Jerusalem was high, and that the level of social status was also high. Moreover, the results showed differences in both creative thinking and social status among high school students due to gender; in favor of males. As for schools, private schools were doing better than the public ones. As for the branch, it was in favor of the scientific one. While for students’ achievement, students with academic averages from (65 -85) were in favor; and as for classes, those in favor were the tenth grade. Whereas, the results showed that there were no differences in the social status according to the class. In addition, the results showed a significant correlation between creative thinking and social status among high school students in the city of Jerusalem

Street lighting poles top solar power generation for typical housing area in Kuwait
The need for energy is on the rise every year in Kuwait. Currently, largely, generation is fossil fuel-based consisting of power generating stations, transmission lines made from high pylons or towers, and distribution-all networked together in a complicated huge power system, the safe operation and stability of which demands for a generation a extra-bit larger than the consumers' demand. This paper presents a logical study as a solution to the increasing demand on electricity from Kuwaiti consumers from alternative source of solar. This study focuses on presenting a scenario of generating electricity from solar panels on top of street lighting poles in Kuwait. A detailed study has been conducted of street lighting poles types varying in sizes, lengths and the consumption of each lighting pole in Kuwait. This paper discusses the possibility of installing solar systems on all Street lighting poles; thus, the size of different solar systems has been calculated suitable to the length of each lighting pole. It will further highlight how to handle the shortage of generating electricity and cover a part of the growing demand using solar panels installed on street lighting poles. An allocated section of the city with installed streetlight poles solar panels make what is like a micro-grid which will prove helpful in meeting some of the energy demand. The resulting micro-solar system is connected directly with the electrical grid and through it; the generated electricity from the solar system will be injected into the electrical grid during the day without using storage batteries. This process, without batteries, allows avoiding extra costs in terms of purchase, installation and periodic maintenance for batteries
Analytical model of Kuwait power consumption
In this paper, assessing an analytical model of Kuwait city power consumption is focused. This includes data per person of energy demand, increasing trends over the years to investigate the rapidly increasing power demand due to the growing number of the population in Kuwait and due to modernization of lifestyle. Therefore, this paper focuses on the analytical model for Kuwait city power consumption showing how the peak-hours demand can be complemented by the solar potential from rooftop solar panels. If the solar energy is associated with the highly potential wind power contribution in DG (distributed generation) form, this will help in the existing capacity deficiency at the national grid level be met by an alternative source of energy. The results of this work will help considerably in reducing the investments in the ongoing practice of building new power plants. The renewable energy sources in the form of DG, both renewable and non-renewable, have become an attractive solution for meeting the energy demand in areas having no access to electricity supply from the utility grid
Effect of nanoparticles on biological contamination of in vitro cultures and organogenic regeneration of banana
Abstract This study aimed to identify biological contaminants of banana in vitro cultures. We also tested the effect of Zn or ZnO nanoparticles on elimination of some bacterial and fungal contaminants and their influence regeneration. Nine strains of bacterial contaminants (Cellulomonas uda, Cellulomonas flarigena, Corynebacterium panrometabolum, Bacillus megaterium, Staphylococcus spp., Klebsiella spp., Erwinia cypripedii, Pseudomonas spp. and Proteus spp.) and four fungal (Fusarium spp., Aspergillus spp., Penicillium spp. and Candida spp.) contaminants were identified in nanoparticles-free media of banana in vitro cultures. They eventually led the explants death. The contamination-free cultures of banana in vitro cultures were obtained as a result of application of nano Zn and ZnO particles to the culture MS media, with no negative effect on regeneration. The callus growth decreased while total proline as well as SOD, CAT and POX activities were increased significantly, when the nanoparticles doses increased. The highest percent of somatic embryogenesis was observed in MS media supplemented with 100 mg/L nano Zn followed by nano ZnO. Excellent shooting, rooting and regenerated plantlets were observed also in MS+100 mg/L nano Zn and ZnO. Regenerated plantlets were successfully acclimatized with about 98% efficiency for the experimental period (one month). Nanoparticles treated somaclones accumulated more proline, chlorophyll, antioxidant enzymes activity and developed more dry weight accumulation than the control. In conclusion, the microbial contaminants in banana in vitro culture can effectively be eliminated by incorporation of nano Zn and nano ZnO particles on growth media at different concentrations. However, 100 mg/L dose was preferable because it showed the best effects on increasing the regeneration of plantlets with well-formed root systems. Further studies are needed to investigate the mechanisms and the side effects of nanoparticles on genetic stability of banana in vitro cultures

The Net Clinical Benefit of Rivaroxaban Compared to Low-Molecular-Weight Heparin in the Treatment of Cancer-Associated Thrombosis: Systematic Review and Meta-Analysis
Cancer-associated thrombosis (CAT) carries significant morbidity and mortality. Low-molecular-weight heparin (LMWH) remains the standard of care, with recent systematic studies suggesting the efficacy and safety of rivaroxaban in the treatment of CAT. Uncertainty, however, remains regarding rivaroxaban efficacy and safety in real-world settings. We performed a systematic review and meta-analysis of studies comparing rivaroxaban to LMWH. We searched PubMed, MEDLINE, and EMBASE. The primary outcome was the net clinical benefit (NCB), while rates of major bleeding (MB), venous thromboembolism (VTE), clinically relevant nonmajor bleeding (CRNMB), and all-cause mortality events were secondary outcomes. Seventeen studies were included in the final analysis. Rivaroxaban had a better NCB (relative risk [RR] = 0.82; 95% CI = 0.75-0.89, Q = 10.51, I2 = 0%), less VTE events (RR = 0.73, 95% CI = 0.65-0.82, Q = 6.76, I2 = 0%), and lower all-cause mortality (RR = 0.72, 95% CI = 0.57-0.91, Q = 32.8, I2 = 79%) compared to LMWH. Additionally, comparable MB events (RR = 1.07, 95% CI = 0.85-1.33, Q = 16.9, I2 = 11%). However, CRNMB events were higher in the rivaroxaban group (RR = 2.02, 95% CI = 1.46-2.80, Q = 9.9, I2 = 19%). Additional analyses demonstrated consistency of results. Our review encompassing data from randomized and real-world data suggested rivaroxaban superiority compared to LMWH in terms of a better NCB, fewer VTE events, lower all-cause mortality, and comparable MB risk while carrying a higher risk of CRNMB. These findings support the use of rivaroxaban in the treatment of CAT. Additionally, it warrants a sizable randomized controlled study testing the superiority of rivaroxaban versus LMWH formulation and ascertaining bleeding outcomes according to cancer type and site.Open access funded by Qatar National Library
Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries
Abstract
Background
Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres.
Methods
This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries.
Results
In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia.
Conclusion
This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries
Current Trends and Approaches in Synonyms Extraction: Potential Adaptation to Arabic
Extracting synonyms from dictionaries or corpora is gaining special attention
as synonyms play an important role in improving NLP application performance.
This paper presents a survey of the different approaches and trends used in
automatically extracting the synonyms. These approaches can be divided into
four main categories. The first approach is to find the Synonyms using a
translation graph. The second approach is to discover new transition pairs such
as (Arabic-English) (English-France) then (Arabic-France). The third approach
is to construct new WordNets by exploring synonymy graphs, and the fourth
approach is to find similar words from corpora using Deep Learning methods,
such as word embeddings and recently BERT models. The paper also presents a
comparative analysis between these approaches and highlights potential
adaptation to generate synonyms automatically in the Arabic language as future
