REMOVAL OF POTENTIALLY TOXIC METALS FROM AQUEOUS SOLUTION USING TETRA PAK INDUSTRIAL WASTE AS BIOSORBENTS

Potentially toxic metals (PTMs) contamination in the water bodies had been a worldwide challenge. Industrialization and anthropogenic activities have produce and discharge wastes comprising organic and inorganic pollutants into the water resources making them hazardous and threatening human health and the environment. Packaging technology for food and beverages such as juices, milk, and other liquids using paper packets, generally known as Tetra Pak, has resulted in the generation of too much waste in the world in recent decades. On the one hand, it appears that the building of composites from Tetra Pak trash allows for maximum recycling of these materials, while on the other hand, the inclusion of Kraft paper, Al, and polyethylene in the packet composition can improve the functional features of the goods. Tetra pak packaging is comprised of three different types of raw materials: cellulose (75 %), low density polyethylene (LDPE) (20 %), and aluminium (5 %).The present research aimed to assess the potential of Tetra Pak industrial waste as biosorbents to remove PTMs such as lead (Pb), Nickle (Ni), and Copper (Cu) from PTMs-artificial contaminated water. Approximately, 0.05 mg/L concentration for Ni, 0.027 mg/L for Pb, and 0.05 mg/L for Cu were artificially added in the water bodied to assess the adsorption efficacy amended with two samples of waste Tetra Pak OTP (sample product1) and DOTP (sample product 2) as biosorbents. The obtained results showed that the maximum Ni adsorption recovery was received by (83 % with DOTP), Pb 52 % with OTP and Cu 32 % with OTP as bio-sorbent amendments. Overall, the present study indicated that the remove of PTMs from dilute aqueous solutions and using industrial waste material as easily available and low-cost sorbent, that can be successfully used to remove pollutants from multi-metal polluted water.</jats:p

Hepatoprotective Effect of Echinops tenuisectus (Compositae) on CCl4 Induced Hepatic Damage in Rats

Flavonoids are known to play a vital role in the management of various liver disorders.They are a large family of compounds synthesized by plants; they belong to a group of natural substances with variable phenolic structures. In this study we aim to scan the types of flavonoids in a newly studied, wild Iraqi plant named Echinops tenuisectus of Compositae family. The medicinal importance of flavonoids on one hand, and the absence of any phytochemical investigation on tenuisectus species of Echinops genus on the other hand, acquired this study itۥs importance. Three flavonoids were identified in the seed,s extract of this plant (Silymarin, Rutin, Quercetin ) by two chromatographic methods, first Thin layer chromatography (TLC) using TLC ready made GF254 plates, UV detector at 254 nm, and two different solvent systems in which the Rf value of the standards (Silymarine, Rutin, Quercetin) matched with the Rf value of the Silymarin, Rutin and Quercetin found in the plant seed٫s extract. High pressure liquid chromatography (HPLC) was the other chromatographic method that used to identify the presence of these flavonoids in the plant seed. The plant seed ۥs aqueous extract was evaluated for its efficacy in rats by inducing hepatotoxicity with CCl4.Single oral dose of 250mg/kg of Seeds Extract was given to ratۥs for 7 days. Serum activities of transaminases (ALT and AST) were used as the biochemical marker of hepatotoxicity. Histopathological changes in ratُُs liver section were also examined. The results of the study indicated that, the pretreatment of rats with Echinops extract before the hepatotoxins agent (CCl4) offered a hepato- protective action.&#x0D; Key words: Echinops, Flavonoids</jats:p

Testing the Feasibility and Potential Impact of a Mindfulness-Based Pilot Program in Urban School Youth.

Mindfulness-based interventions (MBIs) could be effective in engaging children and reducing childhood obesity risk. The purpose of this study was to test feasibility, fidelity, and potential impact of a pilot MBI in urban school youth. A two-group quasi-experimental study was conducted in a Harlem, New York school. Participants comprised 51 students (ages 9-12, 54% female, 85% African American/Black). The experimental (E) group (n = 26) participated in a nine-session pilot MBI. Sessions were 90 min and offered weekly as part of afterschool programming. Children only attending during the school day comprised the control (C) group (n = 25). Process evaluation (e.g., fidelity, reach) was performed. Interviews with the E group were conducted to determine program acceptability. Mindful eating and resilience measures were collected at baseline and post-intervention. Intervention feasibility was high as the retention rate was 100% and fidelity was good as nine out of ten sessions were implemented. Relative to baseline, significant improvements were observed in the C group compared to the E group in the resilience composite score (p = 0.01) and its confidence domain (p = 0.01). A MBI may provide a unique opportunity to engage youth. However, further research is warranted to determine if a MBI could promote health in urban, school-age children

The Response of Chickpea Cultivars to Field Water Deficit

An experiment was carried out in 2006 to investigate the effects of different irrigation regimes (I1, I2, I3 and I4 for irrigation after 80, 110, 140 and 170 mm evaporation from class A pan, respectively) on ground cover, yield and yield components of four chickpea cultivars (Arman, ILC and Jam from kabuli type and Pirooz from desi type) in the field. In most stages of crop growth and development, the ground cover of ILC under different irrigation regimes was higher than that of the other cultivars. The ground cover of all chickpea cultivars was reduced, as water deficit severity increased. Grain yield and yield components were significantly affected by irrigation regimes. Mean grains per plant, 1000 grain weight and grain yield per unit area for I4 were significantly lower than those for other irrigation regimes, but these traits did not differ significantly among I1, I2 and I3. Thus, irrigation after 140 mm evaporation from class A pan could be a suitable irrigation regime for chickpea cultivars, when water resources are limited. Grains per plant did not differ significantly among chickpea cultivars. In comparison, the largest and the smallest grains were obtained from ILC and Pirooz, respectively. In general, mean 1000 grain weight of kabuli type cultivars was higher than that of desi type cultivar. The superiority of ILC in ground cover and 1000 grain weight resulted in higher grain yield, compared to other cultivars. However, no significant differences in grain yield of Arman, Jam and Pirooz were observed. Interaction of cultivar x irrigation for ground cover, grain weight and grain yield per unit area was not significant, indicating that ILC was a superior cultivar under both well and limited irrigation conditions

A Higher-Order Theory for Nonlinear Dynamic of an FG Porous Piezoelectric Microtube Exposed to a Periodic Load

This paper investigates the nonlinear dynamic deflection, natural frequency, and wave propagation in functionally graded (FG) porous piezoelectric microscale tubes under periodic load, hygrothermal conditions, and an external electric field. The piezoelectric material used to make the smart microtubes has pores that may be smoothly changed or uniformly distributed over the tube wall. Here, three types of porosity distribution are taken into consideration. The nonlinear motion equations are constructed using a novel shear deformation beam theory and the modified couple stress theory (MCST). The nonlinear motion equations are solved using the fourth-order Runge–Kutta technique and the Galerkin approach. The effects of various geometric parameters, porosity distribution type, porosity factor, periodic load amplitude and frequency, material length scale parameter, moisture, and temperature on the nonlinear dynamic deflection, natural frequency, and wave frequency of FG porous piezoelectric microtubes are explored through a number of parametric investigations
