Manganese and zinc in the ovipositors and mandibles of hymenopterous insects
(ACADEMIC PRESS LTD, 1998)
X-ray microanalysis of the ovipositor and mandibles of various hymenopterous insects has revealed the presence in many species of up to 10% wt/wt of either zinc or manganese in the cuticle. These metals appear to be involved ...
The leaching of SrS with water and the precipitation of SrCO3 from leach solution by different carbonating agents
(ELSEVIER SCIENCE BV, 1998)
The leaching of strontium sulfide (SrS) with water was investigated, and a comparison of Na2CO3 with CO2 as a carbonating agent for the precipitation of SrCO3 from leach solution was done. The effects of variables for ...
Cholesterol granuloma of the maxillary sinus: six cases from the same region
(HEADLEY BROTHERS LTD, 1998)
It is common to find cholesterol granuloma in the mastoid antrum and air cells of the temporal bone, but it is very rare in paranasal sinuses. In the development of this pathology, the key factor is the presence of a closed ...
Palaeomagnetic study of the Karaman and Karapinar volcanic complexes, central Turkey: neotectonic rotation in the south-central sector of the Anatolian Block
(ELSEVIER SCIENCE BV, 1998)
In the Anatolian sector of the Afro-Eurasian collision zone a palaeotectonic collisional phase (Paleocene to Miocene) responsible for emplacement of the Pontide and Tauride orogens has been replaced by a neotectonic phase ...
Effects of nimodipine and isradipine on endothelin-1-induced contraction of pregnant rat myometrium
(ELSEVIER SCIENCE BV, 1998)
The purpose of this study was to investigate the effect of nimodipine and isradipine on endothelin-1-induced contractions of isolated pregnant rat myometrium. Endothelin-1 at 10(-10)-10(-8) M dose-dependently increased the ...
Strategies for reducing solvent toxicity in extractive ethanol fermentation
(HUMANA PRESS INC, 1998)
Extractive fermentation is a widely preferred technique in which the products of fermentation are removed from the fermentation medium by a proper solvent, in order to avoid the inhibitory effects of the products. In this ...
Placental teratoma - A case report
(ELSEVIER SCI IRELAND LTD, 1998)
We present a rare case of a placental teratoma found within the fetal membranes of an otherwise normal placenta. Lack of a recognizable umbilical cord and no recognizable skeletal development are used as differential ...

In this study, the adsorption of certain water-soluble cationic dyes, (basic blue 9, basic blue 12, basic blue 17, brilliant cresyl blue, janus green B, basic green 4, basic violet 1, basic violet 3, and thionin) onto ...
The effect of different doses of calcitonin on bone mineral density and fracture risk in postmenopausal osteoporosis
(MEDICOM INTERNATIONAL, 1998)
A total of 107 patients were included in the study to determine the effects of different doses of intranasal calcitonin on bone mineral density and fracture risk in postmenopausal osteoporosis. Patients were randomly divided ...
Swelling and dye adsorption properties of radiation induced N-vinyl-2-pyrrolidone/acrylonitrile hydrogels
(SPRINGER VERLAG, 1998)
Swollen hydrogels were prepared by gamma-radiation copolymerization of N-vinyl-2 pyrrolidone and acrylonitrile. The influence of radiation dose and feed composition on the swelling properties, diffusional behavior of water ...
