Investigation of Al-O-Al sites in an Na-aluminosilicate glass
(Indian Academy Sciences, 2004)
This paper reports the presence of Al-O-Al linkages in an aluminosilicate glass where Si/Al = 1 by using 2D O-17 triple quantum MAS NMR technique (3Q MASNMR). The experiments were performed at external magnetic fields of ...
Fungi and aflatoxin B-1 in horse and dog feeds in Western Turkey
(Ecole Nationale Veterinaire Toulouse, 2004)
To evaluate fungi growth and aflatoxin B, contamination in horse and dog feeds, total of 41 feed samples were examined with agar plate incubation and ELISA methods. Fungi growth of the horse feed was not exceeding maximum ...
Investigation of the effect of rake angle on main cutting force
(Elsevier Sci Ltd, 2004)
This paper presents a study of comparison of empirical and experimental results for main cutting force during machining rotational parts by unworn cutting tools. A dynamometer was designed and produced for measuring the ...
Covalent immobilization of invertase on microporous pHEMA-GMA membrane
(Elsevier Sci Ltd, 2004)
Poly (2-hydroxyethyl methacrylate-glycidyl methacrylate) (pHEMA-GMA) membrane was prepared by UV-initiated photopolymerization. Invertase was immobilized by the condensation reaction of the epoxy groups of glycidyl ...
Neurosteroidogenesis in oligodendrocytes and Purkinje neurones of cerebellar cortex of dogs
(Blackwell Verlag Gmbh, 2004)
The cerebellum is a steroidogenic organ that expresses steroidogenic enzymes and produces neurosteroids. Purkinje neurones appear to be the most active steroidogenic cells in the cerebellar cortex. These neurones express ...
Limberg flap repair for pilonidal sinus disease
(Lippincott Williams & Wilkins, 2004)
PURPOSE: There are many methods described for the treatment of sacrococcygeal pilonidal sinus disease, and none of them has been accepted as an optimal modality. Plastic procedures have some advantages, such as short ...
Computer aided modelling of flexible forming process
(Elsevier Science Sa, 2004)
Flexible forming enables the production of sheet metal parts with complex contours and bends by utilising a flexible medium, such as natural or synthetic rubber, as one half of a conventional die set. This study is concerned ...
Phosphorus-nitrogen compounds. spiro- and crypta-phosphazene derivatives: synthesis and spectral investigations. Structure of butane- N, N'-bis(1,4-oxybenzyl)- spiro(propane-1,3-diamino)tetrachlorocyclo-2λ 5, 4λ 5, 6λ 5-triphosphazatriene. Part VII
(Elsevier, 2004)
The condensation reactions between trimer, N3P3Cl6, and diamines, 2 and 4 and {1-{N-[1-(2-hydroxynaphthylmethyl)aminomethylidene]}-2(1H)-naphthalenone, 3, yielded the new spiro-cyclic- (5 and 8) and the novel spiro-phosphazene ...
Performance analysis of ejector absorption heat pump using ozone safe fluid couple through artificial neural networks
(Pergamon-Elsevier Science Ltd, 2004)
Thermodynamic analysis of absorption thermal systems is too complex because the analytic functions calculating the thermodynamic properties of fluid couples involve the solution of complex differential equations and ...
Improved efficacy and tolerability of retinoic acid in acne vulgaris: a new topical formulation with cyclodextrin complex ψ
(Blackwell Publishing Ltd, 2004)
Objectives Retinoic acid (RA) has long been used, both topically and systemically, for disorders of keratinization, acne and related disorders. In the present study, the efficacy and tolerability of topical RA prepared as ...
