The Cambridge Cup has been designed to replace the horseshoe-shaped articular cartilage of the acetabulum and the underlying subchondral bone. It is intended to provide physiological loading with minimal resection of healthy bone. The cup has been used in 50 women with displaced, subcapital fractures of the neck of the femur. In 24 cases, the cup was coated with hydroxyapatite. In 26, the coati...

OBJECTIVE To determine the effect of artificial teats (bottle and dummy) and cups on breast feeding in preterm infants. DESIGN Randomised controlled trial. SETTING Two large tertiary hospitals, 54 peripheral hospitals. PARTICIPANTS 319 preterm infants (born at 23-33 weeks' gestation) randomly assigned to one of four groups: cup/no dummy (n = 89), cup/dummy (n = 72), bottle/no dummy (n = 7...

Pairwise and network meta-analysis (NMA) are traditionally used retrospectively to assess existing evidence. However, the current evidence often undergoes several updates as new studies become available. In each update recommendations about the conclusiveness of the evidence and the need of future studies need to be made. In the context of prospective meta-analysis future studies are planned as...

Many studies in the literature examine income inequality-environment nexus at country level. In this paper, we argue that impact of inequality on sectoral emissions might vary and should be examined by considering sectoral-level differences. We focus 28 OECD economies use DOLSMG, BA-OLS, CUP-FM estimators. Our findings reveal a cointegration relationship exists among series long run, indicating...

This chapter uses fully modified OLS principles to develop new methods for estimating and testing hypotheses for cointegrating vectors in dynamic panels in a manner that is consistent with the degree of cross sectional heterogeneity that has been permitted in recent panel unit root and panel cointegration studies. The asymptotic properties of various estimators are compared based on pooling alo...

Due to limitations of finite element methods and software packages, existing in incorporating the imperfections in to the model. The parametric study of BHF, sheet thickness, die profile radius, punch profile radius, initial yield stress and sheet anisotropy and including imperfections is carried out by the model developed by Ravindra.K.Saxena [1, 2, 3]. The mathematical model is studied and va...

Three major approaches have been classically used to study the release of dopamine (3,4dihydroxyphenethylamine) from dopaminergic terminals of the nigrostriatal pathway in the cat. The amine has been determined in perfusates (1) from the lateral ventricle (Portig & Vogt, 1969; Von Voigtlander & Moore, 1971), (2) from push-pull cannulae introduced into the head of the caudate nucleus (McLennan, ...
