Minimizing total tardiness in a scheduling problem with a learning effect
(Elsevier Science Inc, 2007)
Minimizing of total tardiness is one of the most studied topics on single machine problems. Researchers develop a number of optimizing and heuristic methods to solve this NP-hard problem. In this paper, the problem of ...
Effect of austenitization heat treatment on the magnetic properties of Fe-40wt% Ni-2wt% Mn alloy
(Journal Of Univ Of Science And Technology Beijing, 2007)
The effect of austenitization heat treatment on magnetic properties was examined by means of Mossbauer spectroscopy on an Fe-40wt%Ni-2wt%Mn alloy. The morphology of the alloy was obtained by using scanning electron microscopy ...
Approximation of functions of two variables by certain linear positive operators
(Springer India, 2007)
We introduce certain linear positive operators and study some approximation properties of these operators in the space of functions, continuous on a compact set, of two variables. We also find the order of this approximation ...
Poly[[diaquacaesium(I)]bis(mu(3)-3-carboxy-pyrazine-2-carboxylato)]
(Int Union Crystallography, 2007)
The asymmetric unit of the title compound, [Cs(C6H3N2O4)(2)(H2O)(2)](n), contains one Cs-I cation on an inversion centre, one 3-carboxypyrazine-2-carboxylate anion and one water molecule. In the crystal structure, each ...
Elevated plasma levels of interleukin 1 beta, tumour necrosis factor alpha and monocyte chemotactic protein 1 are associated with pregnancy toxaemia in ewes
(Springer, 2007)
Pregnancy toxaemia is a metabolic disorder that results from an inadequate energy supply to the growing maternal-fetal unit. The mechanism underlying the pathogenesis of the syndrome has not been fully clarified; however, ...

The present study describes pathologic and virologic findings in 15 sheep and 6 goats that died of natural peste des petits ruminants virus Infection in Turkey. Pathologic findings included erosiveulcerative stomatitis, ...
Evaluation of hormone replacement therapy which may have an adrenomedullin-mediated protective effect on cardiovascular disorders
(Springer, 2007)
Background and aims: This study aimed to determine whether there is an adrenomedullin (AM)-mediated protective effect of postmenopausal estroger/progestin therapy (HRT) against cardiovascular disorders. Methods: A total ...
Turn-in folding of the cephalic portion of the lateral crus to support the alar rim in rhinoplasty
(Springer, 2007)
Background: The hypoplastic, weak lateral crus of the nose may cause concave alar rim deformity, and in severe cases, even alar rim collapse. These deformities may lead to both aesthetic disfigurement and functional ...
Use of chemically modified poly( ethylene terephthalate)-g-(acryl amide) fibers for alpha-amylase immobilization
(European Polymer Federation, 2007)
Acryl amide grafted Poly(ethylene terephthalate) (AAm-g-PET) fiber was used for covalent coupling of alpha-amylase. The amide groups of Poly(acryl amide) were converted to the amine groups by Hofmann degradation reaction. ...
Structure and optical properties of Zn1-xFexO thin films prepared by ultrasonic spray pyrolysis
(Elsevier Science Sa, 2007)
Polycrystalline Zn1-xFexO thin films (x <= 0.30) were prepared by ultrasonic spray pyrolysis technique onto glass substrates. The XRD spectra show that undoped ZnO film exhibits wurtzite crystal structure. No detectable ...
