Abstract In this study, Rosa damascena leaf powder was evaluated as a biosorbent for the removal of copper from aqueous solutions. Process variables such dose, pH, and initial concentration were optimized using response surface methodology. A quadratic model established to relate factors based on Box–Behnken design. Analysis variance (ANOVA) used assess experimental data, multiple regression analysis fit it second-order polynomial equation. dose 4.0 g/L, pH 5.5, 55 mg/L determined be best...
This study investigated the phytochemical contents of Taif’s rose pruning wastes and their potential application as phytomedicine, thereby practicing a waste-recycling perspective. In Al-Shafa highland, four Taif farms various ages were chosen for gathering (leaves stems) pharmacological studies. The leaves stems included significant amounts carbohydrates, cardiac glycosides, alkaloids, flavonoids, other phenolic compounds. glycoside flavonoid higher in stems, while alkaloid plant leaves....
Taif rose (Rosa damascena Mill) is one of the most important economic products Governorate, Saudi Arabia. Cadmium chloride (CdCl2) a common environmental pollutant that widely used in industries and essentially induces many toxicities, including hepatotoxicity. In this study, major compounds waste extract (WTR) were identified chemically biologically evaluated. GC–MS analysis WTR indicated presence saturated fatty acids, vitamin E, triterpene, dicarboxylic acid, terpene, linoleic...
All vertebrates have kidneys.However, the shapes, anatomy and functions of different vertebrate kidneys vary, these variations allow organs to be adapted habitat in which animals dwell.The characteristics kidney show much variation groups vertebrates.The type environment, whether aquatic, areal or terrestrial, is importance connection with variations.The function includes osmoregulation, metabolic waste elimination, endocrine addition managing physiological fluids electrolytes.The purpose...
At different parts of the world, Red Seaweeds are one component human diets especially at Southeast Asia. structurally contain bioactive molecules so; we studied effect Chondrus crispus on increasing male albino rat fertility. Twelve rats used in this study as two group pre-treated and post- treated each with 6 animals. The pretreated was dissected before post-treated injection. Each post injected intramuscular 1 mg dose 0.1 ml/ twice per week for 48 day (Mukhtar et al., 2013). results...
Abstract The organization of the roots, ganglia and peripheral distribution cranial nerves fully formed embryos Oreochromis niloticus are examined in transverse serial sections. These carry fibers, which were also analyzed. results this study demonstrated that glossopharyngeal nerve originates by means only one root, leaves cranium through foramen. This gives fibers (visceromotor) to first internal external levator arcus branchialis muscles. There is a single epibranchial (petrosal) ganglion...
Abstract In this study, the Rosa damascena leaf powder was evaluated as a biosorbent for copper removal from aqueous solutions. Optimized conditions of 4.0 g/L dosage, pH 5.5 and initial concentration 55 mg/L obtained by Response Surface Methodology were employed Cu2+ biosorption R. leaves up to 88.7 % removed. The data well fitted pseudo-second order Elovich kinetic models. Langmuir Dubinin-Radushkevich isotherm models also best fit experimental showing monolayer with qmax value 25.13 mg/g...
