APPROXIMATION OF PERIODIC FUNCTIONS BY FEJER SUM AND DE LA VALLEE POUSSIN SUMS
In this paper, we establish several results concerning the approximation of periodic functions by Fejér and de la Vallée Poussin means in Lebesgue spaces L_2π^p.The obtained estimates are expressed in terms of function for L_2 and the second-order modulus of continuity. The approximation of periodic functions by trigonometric polynomials plays a central role in Fourier analysis. Among the classical summation methods, Fejér sums and de la Vallée-Poussin sums provide powerful tools for improving the convergence behavior of Fourier series. In this work, we investigate the approximation of -periodic functions in spaces L_2by these two summation methods. Special attention is given to the relationship between the smoothness of the function, measured via the second-order modulus of continuity, and the rate of approximation. Our results contribute to a clearer understanding of how summability methods refine Fourier approximation and provide effective tools for both theoretical and applied analysis

A Comparative Study of the Nephroprotective Effects of Vildagliptin and Sitagliptin against Gentamicin-induced Nephrotoxicity in Rabbits
Objectives: This study aimed to compare the nephroprotective effects of sitagliptin and vildagliptin on gentamicin-induced nephrotoxicity in rabbits. Materials and Methods: We divided 12 rabbits into four groups (3 per group): 1- Control group (saline only), 2- Diseased group (gentamicin only), 3- Treatment group I (sitagliptin + gentamicin), and 4- Treatment group II (vildagliptin + gentamicin). Serum creatinine was measured, and histopathological study was conducted. Results: Gentamicin significantly elevated serum creatinine and induced inflammation and edema in renal cells. While both sitagliptin and vildagliptin mitigated nephrotoxicity, vildagliptin demonstrated better results, with significantly lower creatinine levels (p=0.000) and better renal histological improvement. Conclusions: Vildagliptin exhibits stronger nephroprotective effects than sitagliptin against gentamicin-induced renal injury, likely due to its stronger anti-inflammatory properties. These results suggest that vildagliptin is preferable for patients at high risk of drug-induced nephrotoxicity, particularly those with diabetes.
A Statistical Study on the Prevalence and Diagnosis of Fibromyalgia in the Syrian Community
Fibromyalgia syndrome is a musculoskeletal disorder that causes chronic pain, muscle spasms, and discomfort in the connective tissues. The pain is often widespread and is accompanied by severe fatigue, sleep disturbances, memory issues, and mood fluctuations. This study aimed to assess the prevalence and diagnosis of fibromyalgia in the Syrian community through a statistical analysis involving 452 participants of various ages and genders, using diagnostic tools approved by the American College of Rheumatology. The results showed a fibromyalgia prevalence rate of 17.5%, with a higher rate among women (19.0%) compared to men (14.2%), though this difference was not statistically significant. Symptom severity increased with age, with those over 50 years old reporting the highest pain levels. There was a strong correlation between the Widespread Pain Index (WPI) and Symptom Severity Score (SSS), indicating that higher pain levels were associated with more severe accompanying symptoms. Additionally, non-working individuals were more likely to be affected than those employed, suggesting a role for social factors and physical activity in disease risk. These findings highlight the need to raise public and medical awareness about fibromyalgia and to develop comprehensive diagnostic and therapeutic strategies that address psychological and social aspects alongside medical management, with an emphasis on physical activity and psychological support to improve patients’ quality of life.

Environmental Costs and the Importance of Environmental Impact Assessments for Projects
Economic and social development entails significant costs that negatively impact the environment, leading to environmental issues manifested in pollution, degradation of quality, and imbalance. These environmental changes have resulted from neglecting environmental considerations in the pursuit of prosperity and increased production. The following facts demonstrate the impact of productive and consumptive activities on natural resources, resulting in their depletion and an increase in waste that needs to be disposed of, causing substantial costs. Therefore, it is necessary to adopt a concept of progress that takes environmental considerations into account and relies on environmentally friendly technology. The costs of economic development include costs related to environmental losses and damages, costs of preventing environmental depletion, and costs of planning for environmental protection. These costs are considered external because they do not appear in the accounts of enterprises or the macroeconomy, even though they lead to significant losses. Recently, countries worldwide are striving to restructure their economies to include environmental issues among their priorities, recognizing that environmental problems may undermine the development process. Thus, it is essential to achieve a balance between development and environmental considerations to ensure resource sustainability and improve quality of life.

Designing an Efficient Deduplication Algorithm for Audio Files in Cloud Storage
Duplicate data poses a significant challenge in big data storage systems as it consumes storage space, affecting data organization, management, and processing. To solvethis problem, hashalgorithms are used to generate hashkeys for files. However, as theamount of data stored in the cloud increases, the search and matching process takes longer. Additionally, hashkeys can match different files, known as collisions, which are related to the length of the hashkey. The longer the key, the less likely collisions will occur.In this paper, we present a technique for eliminating duplicate data at the file level to reduce storage of duplicate audio data in the cloud storage system. The proposed technique aims to reduce the search time for hashvalues by creatinga reduction table with multiple indexes. These indexes are designed based on the audio file format. Therefore, the hashtable includes multiple indexes, each for a specific format. To minimize the probabilityof collisions, MD6 algorithm is used, which produces a key with a length of 512 bits.

The study was done on the two isotopes C^11 and O^15, where the number of ions interacting with the target was found and then the radioactivity was calculated. Comparing the resulting values with the values of the radioactivity when produced by the cyclotron, the values were very low, and by taking advantage of the possibility of changing the pressure of deuterium gas. The radioactivity was calculated when changing the pressure, as the activity value increased to 0.002 GBq for carbon and 0.013 GBq for oxygen with increasing pressure, but we could not reach the required value. The radioactivity was calculated at different frequencies and operating times. We obtained the required value for carbon at 275 Hz, 1000 s, and for oxygen at 75 Hz, 1000 s
New developingand Validation method to Determine Lidocaine Hydrochloride in Raw Material and Injection Forms by Using RP-HPLC
This work was aimed to develop a rapid, simple, sensitive and precise high performance liquid chromatography (HPLC) method for the estimation of Lidocaine hydrochloride (Lido) in both injection dosage forms and raw materials. The chromatographic separation was achieved with acetonitrile:phosphoric acid (pH = 3) in ratio of 30:70 (v/v) as mobile phase on a Shim-pack clc-C8 column (25 cm x 4.6 mm i.d., 5 μm) with UV detection at 212 nm, pump flow rate 1.0 mL/min and sample injection volume 20 μL. The method was validated with respect to linearity, precision, accuracy and specificity. The calibration curve showed good linearity over the concentration range of (2.5 - 250) µg/mL in presence of Caffeine (Caff) as internal standard with limit of detection and limit of quantification were to be 0.31 µg/mL and 0.94 µg/mL, respectively. The developed method was very rapid with a run time of 4.5 min and found to be successively applied for the quality control of (Lido) in pharmaceutical formulations
