A new empirical formula for 14-15 MeV neutron-induced (n, p) reaction cross sections
(Iop Publishing Ltd, 2003)
In this study, we have suggested a new empirical formula to reproduce the cross sections of the (n, p) reactions at 14-15 MeV for the neutron incident energy. This formula obtained using the asymmetry parameters represents ...
Recycling of cutting tools in flexible manufacturing systems
(Taylor & Francis Ltd, 2003)
Flexible manufacturing systems (FMS) are complex, with a high variety of entities. In particular, tool management is critically important for timely manufacture. Since a large number of tools flow in a medium-size FMS, it ...
Effect of some Turkish propolis on the product quantity of Agaricus bisporus (Lange.) Sing
(Pakistan Botanical Soc, 2003)
In this study, the effect of some Turkish propolis on the product quantity of cultivated mushroom Agaricus bisporus (Lange.) Sing. was determined. The samples of propolis were obtained from (Bursa and Erzurum) regions of ...
Sinonasal ossifying fibroma with fluid-fluid levels on MR images
(Amer Soc Neuroradiology, 2003)
Ossifying fibroma is a rare benign neoplasm that usually affects mandibular and maxillary bones. In this report, we present a case of sinonasal ossifying fibroma with fluid-fluid levels and posterior extension toward the ...

Phosphorus–nitrogen compounds. Part VI. Aminolysis of octachlorocyclotetraphosphazatetraene and the crystal structure of 2-trans-6-bis(n-propylamino)-2,4,4,6,8,8-hexakis-tert-butylaminocyclo-2λ5, 4λ5, 6λ5, 8λ5-tetraphosphazatetraene
(Elsevier Science Bv, 2003)
The reactions of 2-trans-6-N4P4(NBPrn)(2)CI6 (2), which was obtained from N4P4Cl8 (1) and n-propylamine, with pyrrolidine and t-butylamine in different solvents have been studied. Compound (2) gave two different products, ...
Fas-mediated pathway and apoptosis in normal, hyperplastic, and neoplastic endometrium
(Academic Press Inc Elsevier Science, 2003)
Introduction. Abnormalities in the control of cell proliferation and apoptosis have been suggested to contribute to the development and progression of neoplasia. There are at least two pathways that activate apoptosis. The ...
Perioperative intravenous adenosine infusion to extend postoperative analgesia in brachial plexus block
(Lippincott Williams & Wilkins, 2003)
Background and objective: Adenosine infusions have been shown to reduce requirements of anaesthetics, to decrease the need for postoperative analgesics and to attenuate hyperaesthesia related to neuropathic pain. We decided ...
Comparative biosorption of mercuric ions from aquatic systems by immobilized live and heat-inactivated Trametes versicolor and Pleurotus sajur-caju
(Elsevier Sci Ltd, 2003)
Trametes versicolor and Pleurotus sajur-caju mycelia immobilized in Ca-alginate beads were used for the removal of mercuric ions from aqueous solutions. The sorption of Hg(II) ions by alginate beads and both immobilized ...
