Sustainable reverse logistics scorecards for the performance measurement of informal e-waste businesses.

Many countries depend on businesses in reverse chains to tackle the environmental pollution caused by the tremendous amount of e-waste. Furthermore, due to the domination of informal businesses in many developing countries, environmental rules are not considered during operation, and these violations tend to affect public health adversely. The government in these developing countries finds it difficult to manage and utilize e-waste due to insufficient resources properly.

Sprue design alterations and its effect on the properties of base metal alloy castings: An in vitro study.

Introduction: To study the effect of various sprue designs on the properties of base metal alloy castings. The base metal alloys are extensively used for their excellent properties such as an increase in hardness, high melting range, high elastic modulus, its compatibility with ceramic material and low cost. However, to improve the properties of the base metal alloys is an ongoing research leading to various modifications in their fabrication procedure - which include sprue designs and their mode of attachment to the wax pattern.

Estimation of Circulating Immune Complexes in patients with Oral Leukoplakia and Oral Submucous Fibrosis: A Case Control Study.

Purpose Of The Study: The present study was conducted to estimate the serum levels of Circulating Immune Complexes in patients with Oral Leukoplakia ,Oral sub mucous fibrosis and normal subjects and correlate these values with the clinical grades of the diseases.

Materials And Methods: The study consisted of 25 Oral Leukoplakia patients, 25 Oral sub mucous fibrosis patients and 25 Normal subjects.

Results: The mean serum levels of CIC showed a gradual increase from normal subjects to Oral Leukoplakia patients and showed a high values in Oral sub mucous fibrosis patients.

Reversion of the downhill course of active lepromatous leprosy by repeated transfusions of fresh blood, donated by healthy but lepromin positive patients.

Earlier studies of immunologic reconstitution therapy of active lepromatous leprosy patients by repeated infusions of viable allogeneic blood lymphocytes indicated a beneficial effect. In order to avoid cell separation and its associated risks, we attempted to transfer immunity passively into seven seriously ill lepromatous patients by repeated transfusions of fresh blood donated by healthy, but tuberculin and lepromin positive, subjects. The results showed clinical improvement in some cases with the elimination of Mycobacterium leprae, histological reversion and return of immunologic responsiveness.

An attempt at passive transfer of immunity to leprosy patients by transfusion of allogeneic lymphocytes, inactivated with mitomycin C.

An attempt was made to repair cell-mediated immunity in 7 patients suffering from lepromatous leprosy and severe erythema nodosum leprosum by intravenous infusion of 400 million allogeneic blood lymphocytes on 3 occasions. The lymphocytes were obtained from lepromin and tuberculin-positive subjects and were inactivated in vitro by treatment with mitomycin C. Immunotherapy with inactivated lymphocytes only modified the severity of erythema nodosum leprosum, without altering other aspects of the disease.
