Lignin isolated from enzymatic hydrolyzed cornstalks (EH-lignin) is a renewable natural polymer noted for its versatility and applicability in a variety of uses. Graft copolymerization of EH-lignin with acrylamide (AM) and the application of this copolymer as a flocculant in dye wastewater treatment were studied in this article. The influences of some factors on yield of copolymer and the graft...

OBJECTIVE Minimally invasive direct coronary artery bypass (MIDCAB) is performed under direct vision without sternotomy or cardiopulmonary bypass. The technique is used in reoperative patients through various incisions to revascularize one or two areas of the heart. The internal mammary artery, gastroepiploic artery, radial artery, or saphenous vein are used as graft conduits. METHODS Anterio...

A complete and permanent hydrophilic modification of polyethersulfone (PES) membranes is achieved by argon plasma treatment followed by polyacrylic acid (PAA) grafting in vapor phase. Both Ar plasma treatment alone and post-PAA grafting rendered a complete hydrophilicity to the PES membranes. The hydrophilicity of the membranes treated with only the Ar plasmas is not, however, permanent. In con...

In this research, (Carboxy-3-oxopropylamino)-3-propylsilylcellulose (COPAPSC) as an organocatalyst, has been synthesized by grafting of succinic anhydride on the NH2-modified cellulose (cellulose functionalized with 3- aminopropyltriethoxysilane). The –CO2H group-functionalized cellulose (COPAPSC) is used as a catalyst for the synthesis of coumarin derivatives from the reaction of phenolic subs...

The effect of grafting and post-grafting temperature on the plant development of two watermelon cultivars at transplantation and on subsequent fruit quality was studied. Watermelon cv. Sugar Baby and Crimson Sweet were self-rooted or grafted onto rootstock RS 841 F1 (Cucurbita maxima × C. moschata) or bottlegourd [Lagenaria siceraria f. clavata] (year 1), plus L. siceraria f. pyrotheca (ye...

the cornelian cherry is one of those less common but, nevertheless, interesting fruit species found in serbia which can be used both for food and medicine. due to a great importance of cornelian cherry fruits as safe food and a wide interest in growing this fruit species, this research was focused on examining the production technique of quality planting material of particularly large-fruit sel...

Background: Commercial cultivation of bitter gourd is affected by biotic stresses like mosaic disease, fusarium wilt and root-knot nematode as well abiotic stress drought. Grafting with resistant rootstocks can be a tool to control these problems. In vegetable production, grafting exploited commercially in many parts the world. The cultivated area grafted solanaceae cucubitaceae plants has incr...
