As economic pressure and competition for budget among federal agencies has increased, there has been an increasing need for more granular data and robust management information systems. This is especially true for the execution of major civilian space programs. This need has resulted in new program management requirements being implemented in an attempt to limit cost and schedule growth. In par...

Cullin-RING (CRL) and RING1-IBR-RING2 (RBR) are two distinct types of ubiquitin ligases. In this issue, Scott et al. show that CRLs activate the RBR enzyme ARIH1 to initiate ubiquitin chains on CRL substrates, thereby marking an unexpected and important advance in our understanding of both enzymes.

The present status of development of software packages and equipment designed for automation of NAA at the reactor IBR-2 of FLNP, JINR, Dubna, RF, is described. The NAA database, construction of sample changers and software for automation of spectra measurement and calculation of concentrations are presented. Automation of QC procedures is integrated in the software developed. Details of the de...

Prevalence of IBR in breeding bulls of Assam was 15.68%. Bulls between the age group of 3-4 years were having the highest prevalence (9.80%) and lowest (1.96%) above 4 years of age. Breed wise, the prevalence rate was highest in Holstein Friesian (9.80%) and lowest in Jersey Cross breed (1.96%).

This paper deals with effective calculation of moments of binary images. Recently, Spiliotis and Mertzios (see ibid., vol.7, p.1609-15, Nov. 1998) published a method based on image block representation (IBR). We propose a refinement of their method which yields exact results and performs even more effectively.

Aim: To provide an up-to-date review of the literature on skin-sparing mastectomy (SSM) for breast cancer (BC). The article also reviews the oncological safety, effects of radiotherapy (RT) on immediate breast reconstruction (IBR), the indications for preserving the nipple-areola complex (NAC) and the emerging role of allogenic grafts as adjuncts to implant in IBR. Methods: Review of the Englis...
