Electroplating and metalworking industries discharge large amounts of heavy metals, including copper (Cu), nickel (Ni) and zinc (Zn) ions, in their effluents have been recognized as a major problem to human health and aquatic life. Copper is highly toxic because it is non biodegradable and carcinogenic, Copper has been reported to cause neurotoxicity commonly known as “Wilson’s disease” due to ...

This study presents the preparation of polypropylene composites filled with mixtures of household waste of mate-tea and wood particles to increase the economic value chain of mate-tea, especially in Latin America. Filler mixtures in proportions ranging from 0 to 60% depending on the type of particle were used. The polypropylene matrix was fixed at 40% and roughness surface and color evaluation ...

in this work, the adsorption of the anionic dye, congo red (cr), from aqueous solution by using tea waste (tw) has been carried out at 30 °c. the equilibrium sorption isotherms and kinetics were investigated. the equilibrium adsorption was studied by the langmuir and freundlich models of adsorption. the experimental results manifested that the langmuir isotherm was the best model for the adsorp...

Effect of different nitrogenous fertilizers on the growth and yield of three years old tea (Camellia sinensis L) plants was investigated at National Tea Research Institute, Shinkiari, (Mansehra) during 2005-06. The nitrogenous fertilizers used were ammonium sulphate, calcium ammonium nitrate, urea and nitrophos along with control receiving no fertilizer. All the nitrogenous fertilizers were app...

For determination of selenium (Se) in biological materials, an improved method based on high performance liquid chromatographic determination of the fluorophore formed by reaction of selenite with 2,3-diaminonapththalene was developed. The concentration detection limits were 0.5 ng/g in dried materials and 0.03 ng/mL in fluid materials. In quadruplicate assays of 11 biological reference materia...

This paper presents data related to an article entitled "Green tea flavor determinants and their changes over manufacturing processes" (Han et al., 2016) [1]. Green tea samples were prepared with steaming and pan firing treatments from the tender leaves of tea cultivars 'Bai-Sang Cha' ('BAS') and 'Fuding-Dabai Cha' ('FUD'). Aroma compounds from the tea infusions were detected and quantified usi...

Plants initially accepted by foraging leaf-cutting ants are later avoided if they prove unsuitable for their symbiotic fungus. Plant avoidance is mediated by the waste produced in the fungus garden soon after the incorporation of the unsuitable leaves, as foragers can learn plant odors and cues from the damaged fungus that are both present in the recently produced waste particles. We asked whet...

tea might be considered as the most popular drink in iran as well as some other parts of theworld. its popularity to some extent depends on its flavor and some other constituents present in its leaves orextract. black tea samples from various agro climatic zones of northeast of iran were evaluated for the chemicalconstituents, polyphenols and metal analysis that determine the quality perception...

OBJECTIVE The purpose of this study was to evaluate risk factors of vaginal cuff dehiscence or evisceration according to the type of operation. METHODS Medical records of 604 women who underwent hysterectomies at Korea University Anam Hospital between June 2007 and June 2011 were reviewed. They were allocated to six groups. The six types of hysterectomies included robotic hysterectomy (n = 7)...

OBJECTIVE The aim of this study was to compare the efficacy and safety of laparoscopic hysterectomy (LH) and Total Laparoscopic Hysterectomy (TLH). METHODS Both types of hysterectomy were performed by retroperitoneal uterine artery sealing using LigaSure™ by four-puncture. A total of 45 patients were operated on by LH and 22 by TLH. The mean operation time, amount of intraoperative bleeding, ...
