To assess the potential for leishmaniasis being transmitted through blood transfusion, we studied the survival of Leishmania in blood products under blood bank storage conditions. We report that L. tropica- or L. donovani-contaminated transfusable blood products are a risk to the blood supply for at least 25 days postdonation under blood bank general conditions. The blood components that have b...

We studied the possibility of performing radical nephrectomy with only predeposit autologous blood transfusion in the treatment of patients with renal cell carcinoma. A total of 15 patients who ranged in age from 32 to 69 years and had a hemoglobin concentration of over 12 g/dl on admission underwent radical nephrectomy with preoperative autologous blood donation. Five patients did not need tra...

BONE MARROW ASPIRATION (BMA) IN ZARIA: A THREE-YEAR RETROSPECTIVE REVIEW. 1 1 1 2 1 1 AWWALU S, HASSAN A, DOGARA LG, MUSA AU, WAZIRI AD, BABADOKO AA for obtaining an aspirate is the Posterior 1 Superior Iliac Spine. This is in contrast to the sternal approach which requires experience and care due to the possibility of cardiac tamponade. A recommended Turn-AroundTime (TAT) of 24 hours makes BMA...

  Background: Reservation of blood leads to blood wastage if the blood is not transfused. Therefore, in some centers only blood type and screen are evaluated. In this study, the efficacy of a blood crossmatch-to-transfusion ratio was measured and then compared with the standard levels. Methods: This prospective study was conducted during one year in a university hospital. During this period, 39...

Background: Many of the multiple traumatized patients who refer to the hospital need transfusion. Transfusion-related acute lung injury (TRALI) is a serious clinical syndrome associated with the transfusion of plasma-containing blood components. In the article, we present a case of TRALI following transfusion of packed red blood cells Case Presentation: A 24 year old male referred to Shahid Beh...

A small number of the logically possible word order configurations account for a large proportion of actual human languages. To explain this distribution, typologists often invoke principles of human cognition which might make certain orders easier or harder to learn or use. We present a novel method for carrying out very large scale artificial language learning tasks over the internet, which a...

P(Z) logic offers a new way to reason about vagueness (ie fuzziness), that treats fuzziness as degrees, distinct from probabilities. One then applies probability distributions over fuzziness. This approach is different from both classical fuzzy logic [26] and possibility theory [1]. P(Z) logic is specially designed for common-sense reasoning.

In order to closely adapt what they produce to what will be sold, it is mandatory for nowadays companies to make early decisions on the base of an uncertain production planning. We suggest a way to explicitly model the uncertainty and imprecision of the demand using possibility theory, all along the MRPII steps: Material Requirement Planning, Load Planning, Scheduling. Though propagation of thi...

The problem of measuring scientific impact is considered. A class of so-called p-sphere indices, which generalize the well known Hirsch index, is used to construct a possibility measure of scientific impact. This measure might be treated as a starting point for prediction of future index values or for dealing with right-censored bibliometric data. Keywords— Hirsch’s h-index, p-sphere indices, s...

This paper proposes a new Information Retrieval Model based on possibility and necessity measures. This model encodes relationship dependencies existing between terms, documents and query by possibilistic networks. The user’s query triggers a propagation process to retrieve necessarily or at least possibly relevant documents.
