Implementation of SIC 2007 for the Vacancy Survey
SUMMARYThe article reports on the work to publish the Vacancy Survey on Standard Industrial Classification 2007 (SIC 2007). The main developments are:
changes to the survey design have led to changes in both the industrial groupings and employment size bands used for samplingcreation of historical series on a consistent basis with the latest dataseasonal adjustment of the new serieschanges made to published outputs, including the impact of the revisions.
Implementation of Standard Industrial Classification 2007: December 2009 update
AbstractONS initially publicised its plans for the implementation of SIC 2007 in Hughes (2008), and this was followed up with an article covering a wider Government Statistical Service angle (Brook and Hughes 2009). This article describes the methodological aspects of the move to SIC 2007; lays out the implications for
National Accounts; and gives an update on the timetable for implementation across the Labour Market Statistics outputs, some of the details of which have changed since the previous publication.
ROOM- AND HIGH-TEMPERATURE MAGNETIC PROPERTIES OF Sm(CobalFexCu0.088Zr0.025)7.5 (x=0.30) SINTERED MAGNETS
The effect of Fe content on room- and high-temperature magnetic properties of Sm(CobalFexCu0.088Zr0.025)7.5 (x=0-0.30) sintered magnets, prepared by the conventional powder metallurgy method, has been systematically studied. With increasing Fe content, the remanences BT and maximum energy products (BH)max at room temperature gradually increase and reach optimal values of 1.055 T with x=0.27 for BT, and 205 kJ/m3 with x=0.21 for (BH)max, respectively, and then drop sharply with further Fe increase. An excessive addition of Fe (x≥0.24) results in rapid deterioration of permanent magnetic properties due to the formation of a considerable amount of FeCo soft magnetic phase. It was found that the effect of Fe content on high temperature stability is huge. The lower the Fe content, the smaller the temperature coefficient of coercivity. When x=0.07, a temperature coefficient of coercivity of -0.14%/K (293-723 K) can be achieved, as compared with -0.23%/K for x=0.21. BT of 0.725 T, bHc of 517 kA/m, iHc of 764 kA/m, and (BH)max of 95 kJ/m3 at 723 K were obtained, and the B-H demagnetization curve remains a straight line.
