This experiment was conducted to determine the effect of chopping corn residue prior to baling on the nutrient composition of cornstalk bales. One dryland corn field planted with a single variety of corn was used. After harvest, one half of the field was chopped with a stalk chopper. The remaining half was not chopped. Each half of the field was then raked into windrows, baled, and wrapped with...

Phosphonates constitute a class of natural products that mimic the properties of the more common organophosphate ester metabolite yet are not readily degraded owing to the direct linkage of the phosphorus atom to the carbon atom. Phosphonate hydrolases have evolved to allow bacteria to utilize environmental phosphonates as a source of carbon and phosphorus. The work reported in this paper exami...

We demonstrate that DNA sediments in the presence of millimolar concentrations of zinc or related metal cations and that EDTA entirely dissolves the sediment. The sedimentation is promoted by alkaline pH but the pH dependence is abolished by submillimolar concentrations of phosphate anions. We suspect that the metal cations generate sedimenting particles of insoluble hydroxides or phosphates fo...

The object of an experiment was inorganic and organic forms of zinc, copper and manganese applied in mineral mixtures to dairy cows. The experiment was carried out on 90 cows with average milk yield for previous lactation of about 9 500 kg milk. The cows received mineral mixtures containing inorganic or organic forms of zinc, copper and manganese for 6 weeks before calving and during the first ...

In this study we compared three methods for the treatment of electroplating sludge highly loaded with zinc and iron: (1) calcium oxide-based solidification/stabilisation; (2) conversion into inert material by adsorption of organic and inorganic pollutants onto activated carbon; and (3) conversion of mobile waste components into insoluble phosphates. All three methods proved highly efficient in ...

An experiment was conducted in the field of Plant Pathology Division, BARI, Cazipur, during Robi 2015-16, 2016-17 and 2017-18 cropping seasons to evaluate efficacy available plant nutrients against purple blotch disease tip-burn onion. Eight different viz. Potassium (ZnSO4 fertilizer), Phosphorus (TSP Boron (Boron Zinc Calcium (CaSO4 Copper (CuSO4), Silicon (silica gel) Manganese (MnSO4 fertili...

Hydrophobic drug candidates require innovative formulation agents. We designed and synthesized lipid-DNA polymers containing varying numbers of hydrophobic alkyl chains. The hydrophobicity of these amphiphiles is easily tunable by introducing a defined number of alkyl chain-modified nucleotides during standard solid-phase synthesis of DNA using an automated DNA synthesizer. We observed that the...

Understanding the relative importance of environment and life history strategies in determining leaf chemical traits remains a key objective of plant ecology. We assessed 20 foliar chemical properties among 12 African savanna woody plant species and their relation to environmental variables (hillslope position, precipitation, geology) and two functional traits (thorn type and seed dispersal mec...

The total ribonucleic acid fraction of mature ovarian eggs of amphibia and fish is composed of two gross fractions, one soluble in cold 0.5 M perchloric acid and the other insoluble in the acid (1, 2). Furthermore, on prolonged treatment with mild alkali, about 80% of the acid is converted to mononucleotides, some 20% being recovered as oligonucleotide fragments, a few of which contain labile p...
