Tree bark species were randomly collected from 65 sites having different anthropogenic activities, such as industrial, high traffic commercial, residential high and residential low traffic volume areas of Ibadan City, Nigeria. Levels of Cd, Cu, Pb, Zn, Co, and Cr of the dry-ashed bark samples were determined by AAS. The mean metal concentrations (mg kg(-1)) in samples from industrial zone were ...

OBJECTIVES To compare the efficacy of two screenings methods for gestational diabetes mellitus, namely the universal screening using 50g Glucose Challenge Test to that of selective screening based on risk factors. METHODOLOGY A cross-sectional study involving 366 women between 24 weeks to 28 weeks gestation who attended a community health clinic for their antenatal care between January to May...

The vacuolar Zn(2+)/H(+) antiporter of Arabidopsis thaliana, AtMTP1, has a cytosolic histidine-rich loop (His-loop). We characterized the structures and Zn(2+)-binding properties of the His-loop and other domains. Circular dichroism analyses revealed that the His-loop partly consists of a polyproline type II structure and that its conformational change is induced by Zn(2+) as well as the C-term...

J. Entomol. Sci. 25(3): 439-449 (July 1990) ABSTRACT There is a paucity of information that describes the relationship between the suite of nutrient elements in tree foliage and associated arthropod assemblages. Foliage from chestnut oak (Quercus prinus), hickories (Carya spp.), yellow poplar (Liriodendron tulipifera), red maple (Acer rubrum), and flowering dogwood (Cornus florida) and associat...

Redundansi jaringan sangat penting untuk memastikan ketersediaan internet dalam komputer.

Pada penelitian ini membandingkan kinerja kedua tersebut menyediakan link Perbandingan didasarkan waktu konvergensi, penyeimbangan beban lalu lintas, secara keseluruhan. Hasilnya...

The study was conducted to evaluate the effects of dietary zinc addition (0 or 15 mg/kg of Zn as inorganic or organic zinc) to three maize-soybean meal basal diets varying in their native Zn, phytic P contents and phytase activity (expressed in kg of feed: P- with 25 mg Zn and 1.3 g phytic P, P+ with 38 mg Zn and 2.3 g phytic P or P+/ENZ being P+ including 500 units (FTU) of microbial phytase p...

Fifty g glucose, 50g maltose and 50g sucrose were loaded to 12 nonobese healthy male volunteers with and without 100 or 300 mg a-glucosidase inhibitor, acarbose, and the inhibitory effect on digestion and absorption of these saccharides was studied. In another series of investigations, acarbose 100 mg a day were orally administered to 12 non-insulin-dependent diabetics for 3 months together wit...

although micronutrients effect on growth and yield of different plants has been intensively investigated, but there is limited information on its effect on grain yield and seed oil content of pot marigold) calendula officinalis l.). in order to investigate the effects of micronutrients (fe, zn and mn) spraying on yield and yield components and seed oil of pot marigold, a field experiment was co...

Abstract Potentially toxic elements (PTEs) from mining industries pollute the surrounding environment and threaten health of communities. Worldwide, exotic indigenous trees are being recommended for green belts to trap dust thereby limit dispersion PTEs. This study compares potential ( Eucalyptus grandis E. camaldulensis ) native Brachystegia longifolia tree species in Zambia accumulate PTEs ev...

Introduction Essential mineral nutrients applied to crops are a cost to growers and, poorly managed, contaminate air and/or water resources. Over the past 30+ years, fertilizer costs (USDA, 2006) and evidence of the negative impact of fertilizer nutrient contamination of air and water resources have increased significantly (Tilman et al., 2002). Therefore, an increase in nutrient efficiency, me...
