ABSTRACT Precise segregation of chromosomes requires the activity of a specialized chromatin region, the centromere, that assembles the kinetochore complex to mediate the association with spindle microtubules. We show here that Mal2p, previously identified as a protein required for genome stability, is an essential component of the fission yeast centromere. Loss of functional Mal2p leads to extreme missegregation of chromosomes due to nondisjunction of sister chromatids and results in inviable cells. Mal2p associates specifically with the central region of the complex fission yeast centromere, where it is required for the specialized chromatin architecture as well as for transcriptional silencing of this region. Genetic evidence indicates that mal2 + interacts with mis12 +, encoding another component of the inner centromere core complex. In addition, Mal2p is required for correct metaphase spindle length. Our data imply that the Mal2p protein is required to build up a functional fission yeast centromere.

A review is given of information on the galactic-centre region obtained from recent observations of the 21-cm line from neutral hydrogen, the 18-cm group of OH lines, a hydrogen recombination line at 6 cm wavelength, and the continuum emission from ionized hydrogen.Both inward and outward motions are important in this region, in addition to rotation. Several types of observation indicate the presence of material in features inclined to the galactic plane. The relationship between the H and OH concentrations is not yet clear, but a rough picture of the central region can be proposed.

Summary Excavation of a road suspected to be Roman revealed a massive foundation surmounted by a flimsy upper road that had been little used except for cart traffic. The road was apparently part of the Stirling to Dumbarton military road, constructed between 1771 and 1780, one ofthe last military roads built in Scotland.

The people who work with computers, the programmers, analysts, and operators who seem to live by rules of their own and seldom leave their own environment, tend to be very cynical towards the stories of electronic brains. This attitude will appear hardly surprising when one eventually learns that the computer is a very simple device and is as far removed from an electronic brain as a bicycle from a spaceship. Programmers in particular are the people most aware that computers are no substitute for the human brain; in fact, the preparation of work to be run on a computer can be one of the most mind-bending exercises encountered in everyday life. Databases and database systems have become an essential component of everyday life in modern society. In the course of a day, most of us encounter several activities that involve some interaction with a database. So in this paper we will talk about how to manage the different type of data involved in any form in the database.
