The success of a satellite mission is dependent on the accuracy of the measurement of its mass properties. Mass properties of a satellite viz. static and dynamic unbalance play a vital role in during satellite launching and attitude and orbital control. Satellite’s center of gravity (staic unbalance) and product of inertia (dynamic unbalance) are measured in Vertical Dynamic Balancing Machine (...

Bachground & Aims: Oral lichenoid reactions (OLR) and oral lichen planus (OLP) are clinically and histopathologically similar but their therapeutic approach are different. Due to the presence of dysplasia in oral lichen planus which effects prognosis, the aim of study was the evaluation of proliferation activity of OLPs and OLRs and their subtypes. AgNOR technique that is inexpensive and easy...

elanoma is a cancerous lesion in the pigment-bearing basal layers of the epidermis and is the most deadly form of skin cancer, yet it is also the most treatable, with a cure rate for early-stage melanoma of almost 100%. Therefore, there is a need to develop computer-aided diagnostic systems to facilitate the early detection of melanoma. The first step in these systems is skin lesion segmentatio...

In virtual colonoscopy, a patient is scanned in both supine and prone positions. However, since the shape of the colon changes substantially, it is necessary to find a good registration between the two scans to help the physician with better polyp detection and to reduce the false positives. To obtain a registration, anatomical features are needed. We use anatomical landmarks to have the necess...

1. It has been shown that powdered hematin is exceedingly resistant to the metabolic action of tissue cells, and wherever injected it will remain for weeks with but slight and slowly progressing alteration. 2. The changes produced in hematin by tissue cells are identical with those changes resulting from the oxidation of hematin by hydrogen peroxid, forming a series of bodies of decreasing colo...

A 20 year old boy presented to the dermatology department for treatment of a congenital icthyosis with a history of generalized erythroderma and trauma related blistering since birth. At the time of presentation he was noted to have red hyperkeratotic plaq corrugated over the joint flexures, elbows, knees after birth erythema and blistering improved but patient developed hyperkeratotic scaling ...

Flexures are components of micro-mechanisms efficiently replacing classical multi-part joints found at the macroscale. So far, flexures have been limited to two-dimensional planar designs due to the lack of a suitable three-dimensional micromanufacturing process. Here we demonstrate and characterize a high-strength transparent monolithic three-dimensional flexural component fabricated out of fu...
