الوصف: Aim To explore nurses' experiences and perspectives about evidence‐based practice (EBP) implementation in the healthcare context. Design A qualitative descriptive study design using focus group discussions (FGDs). Method Sixty‐four nurses who purposefully selected and worked at various healthcare organizations in Bisha Governorate, Saudi Arabia, were included. Eight FGDs were used to obtain data using open‐ended questions. The collected data underwent inductive qualitative content analysis. Results Two main categories were extracted: experiences and perspectives towards EBP. The experiences category emerged into four sub‐categories: familiarity with concepts and benefits, steps, dissemination sources of EBP and sources of EBP knowledge, while perspectives towards the EBP category included four sub‐categories: application of EBP in clinical practice, barriers, facilitators and EBP application methods. The participants experienced being in a non‐supportive and non‐encouraging atmosphere which results from a lack of organizational commitment to EBP implementation and illuminates the complexities involved in the integration process. Conclusion The nurses' experience with EBP indicated that there was limited support for the implementation of this approach. Furthermore, they experienced varying barriers to EBP implementation. They viewed EBP as a complex technique as they lacked knowledge and skills related to the formulation of research questions, and retrieving, applying and disseminating of EBP in clinical practice decision‐making. That is due to barriers pertinent to the individual, organizational and patient factors. The key to successfully implementing an EBP in nursing practice is to promote professional development, comprehensive and continuous training, a culture of change, organizational support and motivation. Clinical Relevance Through the construction and provision of ongoing educational interventions and mentoring programmes about EBP, healthcare organizations and nursing leadership may develop ...

الوصف: Tomato pomace (TP), an antioxidant-rich byproduct, may be suitable for noble applications. The regulation of ROS generation and the anti-inflammatory response can help to prevent ulceration. The purpose of this study was to examine TP for antioxidants, in silico anti-inflammatory properties, and its potential to protect against ulceration and erosion triggered by indomethacin. Tomato pomace extract (TPE) was encapsulated either alone or with probiotics to maximize its potential effect. These microcapsules were investigated in indomethacin-treated rats. TPE demonstrated antioxidant activity as well as high levels of carotenoids (15 mg/g extract) and polyphenols. Because of their binding affinity as well as hydrophobic and hydrogen bond interactions with the active sites of TNF-α and IL-1β inflammatory cytokines, ellagic acid and rutin may be implicated in the anti-inflammatory effect of TPE, according to the docking study. TPE microcapsules, either alone or in combination with probiotics, demonstrated a protective effect against enterocolitis by reducing oxidative stress and inflammation, as evidenced by the decrease in stomach and intestinal MDA, NO, IL-1β, IL-6, and TNF-α levels and the increase in CAT, SOD, and GSH activities. The produced microcapsules are suggested to be promising candidates for protection against gastric ulcers and erosion.

الوصف: Evidence-based practice (EBP) has gained significant importance in clinical practice worldwide, including in nursing. This study aimed to explore the potential impact of applying a web-based training program on nurses’ knowledge, skills, and attitudes regarding EBP. A quasi-experimental pretest-posttest research design was utilized with a purposive sample of 64 professional nurses who agreed to participate. The study took place in different hospitals and primary healthcare centers in the Bisha Governorate, Aseer region, Saudi Arabia. A four-week standardized web-based training program was implemented using an online learning approach. Nurses were provided with an online self-rated data collection tool through the Google Forms platform. The findings indicated a highly significant difference in the total knowledge and EBP skills mean scores of the post-intervention (53.08±15.9) and (66.03±8.95), respectively compared to pre-intervention (P<0.05). Additionally, there was marked improvement in the mean scores of the positive attitude of the training sessions post-intervention compared to pre-intervention. The program was also well-received by the nurses in terms of quality and usability. The program has the potential to enhance nurses’ knowledge, skills, and attitudes toward EBP. Therefore, healthcare organizations may consider adopting web-based training as a means of continuing professional education to promote EBP competencies among nurses.

الوصف: Background and Aim: Mast cells (MCs) play an essential role in regulating tissue homeostasis through various non-allergic immune reactions. This study aimed to describe the salient features of MCs during different phases of the estrous cycle and evaluate the relationship between ovarian hormones and the presence of MCs in camel ovaries. Materials and Methods: Genital tracts (n = 28) of healthy, non-pregnant camels were collected from a local slaughterhouse. The follicular wave stage was determined according to structures on the ovaries using an ultrasound device. Stages were classified as "growing" (n = 12, FØ = 0.3–0.8 cm), "mature" (n = 9, FØ = 0.9–2.2 cm), or "regression" phase (n = 7, FØ >2.5). Blood samples were collected at slaughter to determine serum estradiol-17β and progesterone levels using an immunoassay. Safranin-O, periodic acid/Schiff, alcian blue, or methylene blue stains were used to detect MCs. Results: Follicular numbers at the growing, mature, and regression phases were determined to be 36, 14, and 7 follicles, respectively. Mast cells were widely but sparsely distributed within the ovarian tissue (9.3 MCs in the growing phase, 10.7 in the mature phase, and 7.0 in the regression phase). Typical histological features of MCs were observed in ovarian stromal tissue. Some MCs were found in the interstitial tissue, either near the follicular wall or the interstitial gland. Mast cells were present at a higher density during the mature phase than in the growing and regression phases in the ovarian matrix. A significantly reduced presence of MCs was found in the regression phase than in both the growing and mature phases (p < 0.05). A very strong positive correlation was observed between serum estradiol-17β concentrations and MC density in the ovaries (r = 0.9; p < 0.001). In addition, a strong negative correlation (r = –0.65; p = 0.03) was observed between the presence of MCs and serum progesterone concentrations. Conclusion: These findings suggest that the follicular wave phase and the ...

مصطلحات موضوعية: PMSG, Wind turbine, Ripples, Predictive torque control, Predictive power control, MPPT, Current harmonics

الوصف: The paper aims to develop an improved control system to enhance the dynamics of a permanent magnet synchronous generator (PMSG) operating at varying speeds. The generator dynamics are evaluated based on lowing current, power, and torque ripples to validate the effectiveness of the proposed control system. The adopted controllers include the model predictive power control (MPPC), model predictive torque control (MPTC), and the designed predictive voltage control (PVC). MPPC seeks to regulate the active and reactive power, while MPTC regulates the torque and flux. MPPC and MPTC have several drawbacks, like high ripple, high load commutation, and using a weighting factor in their cost functions. The methodology of designed predictive voltage comes to eliminate these drawbacks by managing the direct voltage by utilizing the deadbeat and finite control set FCS principle, which uses a simple cost function without needing any weighting factor for equilibrium error issues. The results demonstrate several advantages of the proposed PVC technique, including faster dynamic response, simplified control structure, reduced ripples, lower current harmonics, and decreased computational requirements when compared to the MPPC and MPTC methods. Additionally, the study considers the integration of blade pitch angle and maximum power point tracking (MPPT) controls, which limit wind energy utilization when the generator speed exceeds its rated speed and maximize wind energy extraction during wind scarcity. In summary, the proposed PVC enhanced control system exhibits superior performance in terms of dynamic response, control simplicity, current quality, and computational efficiency when compared to alternative methods.
