Mossbauer studies on an AISI 1137 type steel
(Indian Acad Sciences, 2006)
An AISI 1137 type medium carbon steel was studied by means of scanning electron microscopy and Mossbauer spectroscopy. This steel in as received state at room temperature was ferritic. Different heat treatments on related ...
Some elastic properties and phase transitions in some alkali halides using interatomic potential model
(Polish Acad Sciences Inst Physics, 2006)
We have predicted the phase transition pressure in some alkali halides using an interatomic potential approach based on rigid ion model. This potential form represents the composite form of the inverse power dependence and ...
On approximation properties of a family of linear operators at critical value of parameter
(Academic Press Inc Elsevier Science, 2006)
We introduce the family of linear operators [GRAPHICS] associated to a certain "admissible bunch" of operators S-t, t > 0, acting on L-p (R-n, dm, and investigate the approximation properties of this family as alpha -> ...
Testicular nitric oxide and thiobarbituric acid reactive substances levels in obstructive azoospermia: A possible role in pathophysiology of infertility
(Hindawi Ltd, 2006)
Objective. The aim of the study is to evaluate the levels of nitrite/nitrate and thiobarbituric acid reactive substances (TBARS) and their relationship with seminal parameters in experimental obstructive azoospermic rats ...
Similar effects of general and spinal anaesthesia on perioperative stress response in patients undergoing haemorrhoidectomy
(Hindawi Ltd, 2006)
Surgery induces release of neuroendocrine hormones (cortisol), cytokines (interleukin-6: IL-6, tumour necrosis factor-alpha: TNF-alpha), acute phase proteins (C-reactive protein: CRP, leptin). We studied the effects of ...
Formation of silicon nanocrystals in sapphire by ion implantation and the origin of visible photoluminescence
(Amer Inst Physics, 2006)
Silicon nanocrystals, average sizes ranging between 3 and 7 nm, were formed in sapphire matrix by ion implantation and subsequent annealing. Evolution of the nanocrystals was detected by Raman spectroscopy and x-ray ...
Pertussis; Still a clinical diagnosis
(2006)
Boğmaca, öksürük nöbetleriyle karakterize akut, bulaşıcı bir solunum yolu enfeksiyonudur. Bebeklerde en önemli ve ciddi komplikasyonu pnömoniye bağlı solunum yetmezliğidir. Nöbetlerle boğulur tarzda öksürük ve siyanoz ile ...
