Design optimization of cutting parameters when turning hardened AISI 4140 steel (63 HRC) with Al2O3+TiCN mixed ceramic tool
(Elsevier Sci Ltd, 2007)
Due to their high hardness and wear resistance, Al2O3-based ceramics are one of the most suitable cutting tool materials for machining hardened steels. However, their high degree of brittleness usually leads to inconsistent ...
Determination of residual stresses based on heat treatment conditions and densities on a hybrid (FLN2-4405) powder metallurgy steel using artificial neural network
(Elsevier Sci Ltd, 2007)
This paper presents a new approach based on artificial neural networks (ANNs) to determine the residual stresses in PM steel based nickel (FLN2-4405). This study consists of two cases: (i) The experimental analysis: The ...
Effect of chronic diseases and associated psychological distress on health-related quality of life
(Wiley, 2007)
Background: The purpose of this study was to clarify the correlations between the presence of comorbidities and psychological distress and health-related quality of life (HRQL). This was a population-based cross-sectional ...
Superoxide dismutase activity in synovial fluids in patients with temporomandibular joint internal derangement
(W B Saunders Co-Elsevier Inc, 2007)
Purpose: To measure the activity of superoxide dismutase (SOD) in the synovial fluid of patients with temporomandibular joint internal derangement and to show the relationship between the activity of SOD and the severity ...
Analysis of free and forced vibration of a cracked cantilever beam
(Elsevier Sci Ltd, 2007)
Structures are weakened by cracks. When the crack size increases in course of time, the structure becomes weaker than its previous condition. Finally, the structure may breakdown due to a minute crack. Therefore, crack ...
Size distribution of dispersed luteal cells during oestrous cycle in angora goats
(Blackwell Publishing, 2007)
The present study examines the size distribution of the goat steroidogenic luteal cells throughout the oestrous cycle. Corpora lutea (CL) were collected after laparatomy on days 5, 10 and 16 of the oestrous cycle. Luteal ...
On behaviour of the Riesz and generalized Riesz potentials as order tends to zero
(Element, 2007)
In this paper, we present the Riesz potentials I-alpha and the generalized Riesz potentials I-v(alpha) as the families of positive linear operators, depending on parameter alpha > 0. We investigate their pointwise convergence ...
Dipotassium maleate with boric acid
(Blackwell Publishing, 2007)
In the title compound, poly[(mu(3)-boric acid)-mu(4)-maleato-dipotassium], [K-2(C4H2O4){B(OH)(3)}](n), there are two independent K+ cations, one bonded to seven O atoms ( three from boric acid and four from maleate), and ...
Unilateral transient reactive papulotranslucent acrokeratoderma in a child
(Wiley, 2007)
Transient reactive papulotranslucent acrokeratoderma is a rare, acquired, reactive, and episodic disorder of the palmar skin. Herein I report on a 6-year-old child with unilateral involvement and associated with ipsilateral ...
Do cerebral blood flow velocities change in iron deficiency anemia?
(Lippincott Williams & Wilkins, 2007)
Infants with iron deficiency had lower scores when tested for mental and motor development than their peers with better iron status. The aim of this study was to examine cerebral blood flow velocity in infants with iron ...
