water soluble amphoteric graft copolymers of polysaccharide were synthesized via grafting of cationic monomer onto the sodium carboxymethylcellulose ()cmc)( and then used as a shale stabilizer in the water-based drilling fluids. accordingly, five types of cmc-graft copolymers with different ratios of acrylamide am)( and diallyldimethylammonium chloride dadmac)( were synthesized. grafting of mon...

Grafting is an ancient technique that involves the physical joining of genotypically distinct shoot and root systems, in order to achieve a desirable compound plant. This practice widely used modern agriculture improve biotic abiotic stress tolerance, modify plant architecture, induce precocious flowering rejuvenate old perennial varieties, boost yield, more. Beneficial new rootstock-scion comb...

UNLABELLED Sectioned facial nerves can be repaired with grafting or end-to-end anastomosis. OBJECTIVE To discuss these repair procedures and what can be expected of them. METHOD Seven patients with sectioned facial nerves were included in the study. Four underwent grafting and three were offered end-to-end anastomosis. Facial nerve palsy was iatrogenic in five patients and was caused by bul...

Background—The prevalence of diabetes mellitus is increasing at an unprecedented rate, affecting nearly 8% of the population. Previous studies have demonstrated a potential benefit for surgical over interventional revascularization in this group of patients. Similarly, studies have shown the superiority of bilateral internal mammary artery (BIMA) grafting over single internal mammary artery (SI...

Radiation grafting of monomers on polymers is radical polymerization which usually takes place in viscous medium and quite often in a micro-heterogeneous semicrystalline matrix. The role of kinetic and structural factors in the graft polymerization was investigated. Grafting of styrene on polyethylene and polypropylene was initiated by radiation methods (direct irradiation of polymer and monome...

PURPOSE Multiple bone augmentation techniques are available to allow implant placement in the atrophic maxilla. However, questions remain, regarding which methods are most predictable and have the best dental implant survival rate (SR) in grafted bone. The aim of this systematic review was to evaluate literature from the last 30 years to determine predictability of bone grafting of the edentulo...

conclusions gargling a green tea solution, an anti-inflammatory, natural, and harmless substance, can reduce the pain of sore throat in patients after endotracheal extubation. objectives the aim of this study was to investigate the effect of green tea gargling on sore throat after coronary artery bypass grafting (cabg). patients and methods this was a single-blind, randomized clinical trial, in...

The definition of the grafting operation for quasifuchsian groups is extended by Bromberg [Br] to all b-groups. Although the grafting maps are not necessarily continuous at boundary groups, in this paper, we show that the grafting maps take every " standard " convergent sequence to a conver-gent sequence. As a consequence of this result, we extend Goldman's grafting theorem for quasifuchsian gr...

BACKGROUND Injury to the prostatic plexus may occur during radical prostatectomy even with the use of minimally invasive techniques. Reconstruction of these nerves by interpositional nerve grafting can be performed to reduce morbidity. Although the feasibility of nerve reconstruction has been shown, long-term functional outcomes are mixed, and the role of nerve grafting in these patients remain...
