PURPOSE To describe a technique that preserves anterior and posterior alternate ledges in a closing wedge osteotomy. METHODS Five patients aged 14 to 19 years underwent a closing wedge osteotomy for genu valgum in 8 limbs using a reciprocating ledge technique. A unicortical wedge of bone was removed, with the anterior and posterior cortices spared. The anterior cortex at the proximal level an...

In this paper, a knowledge-based approach to Internet authorizations is proposed by using Public-Key Infrastructure (PKI) based digital certificates, trust models, Role-Based Access Control (RBAC), and intelligent backtracking. Security policies are expressed as the rules in a knowledge base. An inference engine is utilised to evaluate policies, dynamically assign roles to Internet users, and r...

BACKGROUND AND OBJECTIVES The REAL/WHO classification constitutes a new tool for the better understanding and treatment of malignant lymphomas. The authors focus on the key features of aggressive B- and T-cell lymphomas, aiming to contribute to the cross-talk between pathologists and clinicians. DATA SOURCES AND METHODS Each lymphoma entity is analyzed on the basis of the most representative ...

It has been observed that the root canal treatment for the preservation of tooth having periapical pathology has shown over 90% of success whereas in the case where the canal is calcified, perforated, ledge is formed, and cases where symptoms still exist after treatment, endodontic treatment may not be the solution in attaining a successful treatment. Thus Apisectomy would generally be done to ...

INTRODUCTION Meningiomas are the most frequent group of intracranial tumours, accounting for around a third of all primary brain tumours. In most cases, they are benign neoplasms that start in the cells of the arachnoid mater and may be located in the intracranial and spinal cavities. AIM To perform a review of the information available on intracranial meningiomas that allows us to update cur...

2014 We have observed the equilibrium shape of a Smectic B monodomain in contact with a Smectic A phase and how a grain boundary deforms the Smectic B-Smectic A interface in the presence of a temperature gradient. The chosen material is the 40.8 (butyloxybenzilidene octylaniline). By using the Wulff construction and the T.L.K. model, we calculate both the surface free energy of a facet parallel...

I ncreasingly, businesses are using social networking technologies to foster know­ ledge management and transform their ap­ proach to marketing, advertising, research, and stakeholder engagement. As individuals and businesses discover the potential and value of IT­enabled social networks, there’s a need to arti culate and quantify the antecedents of their adoption, diffusion, business value, an...

With rapid solidification following pulsed laser melting, we have measured the dependence on interface orientation of the amount of solute trapping of several group III, IV, and V elements (As, Ga, Ge, In, Sb, Sn) in Si. The aperiodic stepwise growth model of Goldman and Aziz accurately fits both the velocity and orientation dependence of solute trapping of all of these solutes except Ge. The s...
