Radiation induced superabsorbent hydrogels. Acrylamide/itaconic acid copolymers
(WILEY-V C H VERLAG GMBH, 2001)
Acrylamide/itaconic acid hydrogels in the form of rods are prepared by gamma -irradiation of ternary mixtures of acrylamide/itaconic acid/water with 2.00-5.71 kGy gamma -rays. Spectroscopic and thermal characteristic the ...
Sequential ultrasonic leaching of strontium from sediments
(GORDON BREACH PUBLISHING, TAYLOR & FRANCIS GROUP, 2001)
The effects of ultrasonic excitation on the sequential leaching of Sr from sediments have been investigated. The sequential leaching scheme of Tessier partitions metals in sediments into exchangeable, carbonate bound, oxide ...
Bilateral chylothorax caused by pleuropulmonary lymphangiomyomatosis: A challenging problem in thoracic surgery
(TAYLOR & FRANCIS AS, 2001)
Massive left-sided pleural effusion in a 35-year-old man was initially diagnosed as idiopathic spontaneous chylothorax and treated with serial thoracenteses and left thoracotomy. Six weeks later, a right thoracotomy was ...
Disinfection of E-coli by the Ag-TiO2/UV system: lipidperoxidation
(ELSEVIER SCIENCE SA, 2001)
The photocatalytic disinfection of Escherichia coli, a pathogenic micro-organism. was investigated. An aqueous suspension of the micro-organism (1 x 10(8) cfu/ml) and neat TiO2 or silver-loaded TiO2 Were irradiated with a ...
Host location and oviposition in a basal group of parasitic wasps: the subgenual organ, ovipositor apparatus and associated structures in the Orussidae (Hymenoptera, Insecta)
(SPRINGER, 2001)
Anatomical studies and behavioural observations indicate that representatives of the Orussidae use vibrational sounding to detect suitable oviposition sites. During host location, vibrations generated by tapping the tips ...
Nicotine-selective radiation-induced poly(acrylamide/maleic acid) hydrogels
(PERGAMON-ELSEVIER SCIENCE LTD, 2001)
Nicotine-selective poly(acrylamide/maleic acid) (AAm/MA) hydrogels prepared by gamma -irradiation were used in experiments on swelling, diffusion, and interactions of the pharmaceuticals nicotine, nicotinic acid, nicotinamide. ...
A novel concentration method for concentrating solutions of protein extracts based on dialysis techniques
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2001)
…
Use of superswelling acrylamide/maleic acid hydrogels for monovalent cationic dye adsorption
(JOHN WILEY & SONS INC, 2001)
Acrylamide/maleic acid (AAm/MA) superswelling hydrogels prepared by irradiation with gamma radiation were used in experiments on swelling, diffusion, and adsorption of some water-soluble monovalent cationic dyes such as ...
An existence theorem for the commutative neutrix product of distributions
(KOSSUTH LAJOS TUDOMANYEGYETEM, 2001)
In this paper we prove that the commutative neutrix product of the distributions x(+)(-r) and x(+)(-delta) exists for r, s = 1, 2,....
In vitro dynamic swelling behaviors of polyhydroxamic acid hydrogels in the simulated physiological body fluids
(SPRINGER-VERLAG, 2001)
Influence of some simulated physiological body fluids on the dynamic swelling behaviour of polyelectrolytic hydroxamic acid hydrogels (PHA) was investigated at 37 degreesC in vitro. The simulated physiological body fluids ...
