The Skyrme (SLy4) potential was utilized to compute the zirconium isotopes' wave functions with mass numbers 90, 92, and 94. By employing the Gloeckner interaction and bare G-matrix, the computed results showed good agreement with the available experimental information on the aforementioned nuclear features of all the above isotopes. Additionally, the spins and parities of energy levels were confirmed and determined in accordance with certain empirical values. Furthermore an acceptable agreement for transition strengthsB(E2;2_1^+→0_1^+ ) for 90,92,94Sr , and the dipole magnetic moment of the ground state in the90Sr isotope, was observed with the available experimental values. In these calculations, new values were predicted for the above nuclear properties, which had not been previously determined experimentally.\u0000KEYWORDS:\u0000energy spectra; gloeckner interaction; model space; nuShellX code; skyrme potential; transition strengths","PeriodicalId":517170,"journal":{"name":"Scientific Journal of King Faisal University: Basic and Applied Sciences","volume":"51 21","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141650074","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The strawberry extract exhibited a significant inhibitory effect on Enterococcus spp., with a zone of inhibition measuring 23 and 26 mm. Conversely, the green tea extract demonstrated a weaker inhibitory effect, with a zone of inhibition measuring 19 mm. These findings underscore the potential of ethanolic strawberry extract as a natural antibacterial agent against Enterococcus spp., offering insights for further research and potential therapeutic applications in the treatment of urinary tract infections caused by these bacteria.\u0000KEYWORDS\u0000acetone, catechin, flavonoids, gelatinase, hemolytic, vancomycin","PeriodicalId":517170,"journal":{"name":"Scientific Journal of King Faisal University: Basic and Applied Sciences","volume":"36 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141280472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using the partial adjustment model, the most important results were that the water balance deficit in dates amounted to about 9.10 billion m3 during the study period (2000–2021). Based on the forecasting models used, date exports are expected to grow by about 21% annually during the period (2022–2030). By comparing the cash return of a unit of water used in the production of dates with the cost of its production, it was found that it represents 62% of the value of the cost of water used in the production of the unit. It was also found that non-Gulf Arab countries purchase about 45% of the Kingdom’s date exports with a cash return of approximately $0.20/m3 from virtual water. The cash return per unit of water in other countries is estimated to be $0.50 to $0.69/m3. Therefore, the study recommends reconsidering the export of dates and directing them toward high-yield markets to maximize the cash return of virtual water units.\u0000KEYWORDS\u0000water resources, cash return, water unit, water balance, partial adjustment, foreign trade","PeriodicalId":517170,"journal":{"name":"Scientific Journal of King Faisal University: Basic and Applied Sciences","volume":"117 46","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140379036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results indicate increased production costs due to the war and a decreased net return for the three production capacities and the sample average: the return index on invested dollars before the war was 0.71, 0.89, 1.0, and 0.87, respectively; however, this decreased after the war to 0.35, 0.53, 0.66, and 0.51, respectively. The war has led to an increase of 43.93% in the minimum price as the production costs have risen. The value of the price elasticity of supply was about 0.233 at the minimum price and 0.041 at the current price level. If the prevailing price increases by 10% to become $2.13 thousand per ton, the price elasticity of supply becomes about 0.037.

The iterative prediction and update process employed by the algorithm aids in achieving smoother and more accurate position estimations. To assess the efficacy of the adaptive Kalman filtering approach, a comparative analysis was performed against a multistage filter. This filter employed a sequence of median filters with progressively increasing window sizes to eliminate outliers and artifacts while retaining the intricate details of the drawings. A comprehensive evaluation was performed via a detailed comparison of noise reduction performance and preservation of details between the two techniques. The experimental findings unequivocally established the superiority of the adaptive Kalman filtering approach in noise reduction and accuracy enhancement of the recorded positions. The proposed algorithm surpassed the multistage filter, demonstrating superior noise reduction capabilities while maintaining the desired level of detail in diagonal line drawings. The findings are expected to contribute to the advancement of state estimation techniques in dynamic systems, with a focus on augmenting accuracy and detail preservation.\u0000KEYWORDS\u0000dynamic system, impulse noise, measurement noise, multistage filter, outlier removal, position estimation","PeriodicalId":517170,"journal":{"name":"Scientific Journal of King Faisal University: Basic and Applied Sciences","volume":"94 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140261217","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These urinary crystals are traditionally created in the lab using the gel growth process and a silica gel medium at a specified pH. The inhibitory effects can be analysed by using the extracts of herbal plants. In the present study, ethanol extracts of leaves of Alternanthera sessilis, seeds of Cucurbita maxima and flowers of Aerva lanata are investigated for their inhibitory activity against the whewellite urinary crystals. They are characterized using Fourier transform infrared spectrum and their crystalline nature is examined through powder X-ray diffraction.

In a laboratory furnace, treatment at different temperatures (800, 900 and 1000 °C) was performed. Then, the sample was treated with diluted HCl (1:1) with heating to 60 °C to isolate the silica; after that, it was treated at 900 °C for 30 min to form SiO2 nanoparticles with a yield of 68% and a purity of up to 99.5%. The resulting silica (SiO2) was characterised by XRD and AFM techniques. Results from the two- and three-dimensional images captured by AFM showed the formation of silica nanotubes with a surface roughness (Ra) of 78 nm.
