The effects of activating agent concentration on the pore structure and surface chemistry activated carbons derived from olive stone with chemical activation method using phosphoric acid as were studied. Mass changes associated impregnation, carbonization washing processes measured. With H3PO4 dilute solutions (60, 70, 80 wt% H3PO4), loading substance CS increases concentration. solution seems to control in preparation AC stones by activation. ACs have been characterized results obtained N2...
Bronchial asthma is one of the most prevalent diseases in Arab children. Environmental pollution has been suggested to be considered causative asthma, nasal symptoms and bronchitis both children adult. The objectives this study were evaluate association between serum polycyclic aromatic hydrocarbons (PAHs) levels, allergic outcomes among Saudi aged up 15 yrs. We hypothesized that increased PAHs are associated with allergy, or respiratory symptoms. A total 195 (98 pediatric patients 97...
Biochar derived from agricultural biomass waste is increasingly recognized as multifunctional material for various applications according its characteristics.It therefore essential to investigate biochar properties before large-scale application.In this study, rice straw-derived biochars produced at different temperature (550, 650, 750 o C).The resulting were subjected liquidphase oxidation by agents including KOH, HNO 3 , H 2 SO 4 O and KMnO obtain with properties.Pore structure...
In this work, the adsorption of polycyclic aromatic hydrocarbons (PAHs) from aqueous solution by rice husk activated carbon (RHAC) was compared with using conventional, powdered as adsorbent. The adsorbent capacity RHAC found to be higher than all other agricultural and industrial adsorbents evaluated. kinetics PAHs similar even after 24 hours. removal PAH occurred in following order: naphthalene < phenanthrene pyrene. Our study results show that molecular weight solubility play vital...
Biochar derived from agricultural biomass waste is increasingly recognized as a multifunctional material for various applications according to its characteristics. In this study, rice straw–derived biochars were produced at different temperatures (550, 650, 750°C), then they modified by using oxidizing agents, including KOH, HNO3, H2SO4, H2O2, and KMnO4. The influence of carbonization temperature the agent's nature on surface chemistry was investigated. Fourier transform infrared (FTIR)...
Postmenopausal osteoporosis is an important metabolic bone disease characterized by rapid loss occurring in the postmenopausal period. Recently, most prevalent form of clinically significant osteopenia and involves various inflammatory conditions. The aim study to evaluate association between proinflammatory markers (interleukin [IL]-1β, IL-6, TNF-α) with turnover (BTMs) Saudi women without osteoporosis. A total 200 ≥50 years old, 100 (control) were recruited under supervision qualified...
Zirconia powder was synthesized via a sol gel method and placed in batch reactor for cesium removal investigation. X-ray analysis Fourier transform infrared spectroscopy were utilized the evaluation of developed adsorbent. The adsorption process has been investigated as function pH, contact time temperature. is strongly dependent on pH medium whereby efficiency increases turns to alkaline range. initially very fast maximum attained within 60 min contact. A pseudo-second-order model...
This study aimed to investigate the prevalence, trends, and predictors of coffee consumption among Saudi female students its association with anthropometric demographic variables. A survey-based using a face-to-face interview was designed, 930 (aged 21.5 ± 2.1 years) apparently healthy from different departments King Saud University participated. The prevalence significantly higher (88.2%, p < 0.03) in central Riyadh region. Coffee consumers had being overweight than non-consumers (p =...
Oxidative stress results from an imbalance between free radical production and antioxidant defense, significantly impacting neonatal health, particularly in preterm infants with immature systems. This study aims to assess oxidative Saudi neonates by measuring key antioxidants, both enzymatic (superoxide dismutase, catalase, glutathione peroxidase) nonenzymatic (glutathione, bilirubin, uric acid), comparing them across sex (male vs female) term status (full preterm). A total of 110 (55 normal...
Adipose tissue secreted cytokines (adipocytokines) have significant effects on the physiology and pathology of human metabolism relevant to diabetes cardiovascular disease. We determined relationship pattern these circulating hormones with obesity-related phenotypes whether such is transmitted from parent offspring. A combined total 403 individuals 156 consenting Saudi families divided into initial (119 123 adults 131 children) replication (37 58 91 cohorts were randomly selected RIYADH...
Vitamin D deficiency is an increasingly recognized comorbidity in patients with type 1 diabetes mellitus (DMT1), suggesting that vitamin might play a role DMT1. We aimed to determine and compare the status of Saudi adults without A total 60 DMT1 from Diabetes Clinics non-DM, healthy controls were included study. The mean age for those was 25.9 ± 16.1 years versus 36.7 3.6 among controls. measured serum 25-hydroxy (25OHD), calcium, cholesterol, blood glucose, HDL, triglycerides compared...
