For the development of management strategies in sustainable agriculture it is necessary to describe and predict the role of soil microbes in different management systems. The classical approach uses the microbial biomass as the key parameter for the entire system. but for ecological purposes Ihe variability of biotic parameters in time and space has to be better described. Momvcr. the biomass a...

Local control rates for Giant Cell Tumor of Bone (GCT) have been reported in a large number of retrospective series. However, there remains a lack of consensus with respect to the need for a surgical adjuvant when intralesional curettage is performed. We have systematically reviewed the literature and identified six studies in which two groups from the same patient cohort were treated with intr...

OBJECTIVES To study the long-term effects of oral estriol tablets on the endometrium of postmenopausal women by TVS and histology. METHOD This was a cross sectional, parallel-group, multicenter trial of 241 postmenopausal women, out of whom 125 were treated with oral estriol and 116 were untreated controls. Endometrial histology using Pipelle biopsies and/or dilatation and curettage (D&C) was...

a b c d d Aims: This randomized double blind study was carried out to investigate effect of intrathecal fentanyl on incidence and severity of intraoperative shivering on patients undergoing lower abdominal surgeries under spinal anesthesia. Method: 120 patients undergoing lower abdominal surgeries under spinal anesthesia were assessed in a randomized fashion. They were divided in to two groups....

A group is simple if it has no non-trivial, proper, normal subgroups. It’s not hard to show that if n > 4, then An is a simple group. Recall that for a field F , SLn(F ) is the subgroup of GLn(F ) consisting of matrices with determinant 1. Define PSLn(F ) = SLn(F )/Z(SLn(F )). Here, S is for “special” and P is for “projective.” It can be shown that PSLn(F ) is simple for all n and F except for ...

• In the usual procedure for determination of indicator dilution curves, the sensing or measuring device is placed at some distance from the sampling site. The fluid is transported by a sampling system, usually a cathe-ter, from the withdrawal site to the sensing point. This sampling system always introduces some distortion in the time-concentration curve, so that the recorded curve is not the ...

Caesarean scar pregnancy (CSP) occurs when an embryo implants in a previous caesarean section scar. It has a reported incidence of 1 in 1800. Various surgical and medical techniques have been described in case reports for the management of CSP. These techniques are usually undertaken in tertiary level units with significant resource availability. In this paper, we present a new clinical perspec...

Amit Keren, Henri Alloul, Philippe Mendels, and Yohsuke Yoshinari* Laboratoire de Physique des Solides, URA2 CNRS, Université Paris Sud, 91405 Orsay, France (Received 9 October 1996) NMR transverse relaxation (TR) measurements of 17Os2, 3d in YBa2Cu3sO12cOcd7 are presented. A Gaussian-like relaxation is found. The origin of this relaxation is investigated by varying c, the temperature, the exte...
