Second Equal Treatment Act for the commercial sector

This book analyses one of the first pieces of legislation promoted by Angela Merkel, who started her political career as a minister for women's equality under Helmut Kohl. The name of the Act, Second Equal Treatment Act, allured to the Equal Treatment Act of the 1950s which implemented the barest minimum requirements to make the German constitution's demand to guarantee equal rights for women more than a hollow formula. However, this Act, while abolishing blatant discrimination of women through statute in fields such as family law, did nothing to further substantive equality. In 1990, when Germany was reunited, women from Eastern Germany had a first hand experience what the absence of such furtherance meant under capitalism. Used to being at nor risk to fall into poverty just because they divorced, or decided to become a mother without male protection, to being in full employment and not at the mercy of payments by their husbands, women from Eastern Germany were dismissed in large numbers, and found themselves sent back to the kitchen. The first minister for women affairs from their ranks made the "2nd Equality Act", but this act did little more than the minimum required by the EEC legislation. Again, substantive equality was not addressed through German Federal legislation. This was left to some of the German states - whose competences were limited to the public services. Most of those states which did create positive action measures for women employed in the public services were governed not by Christian Democrats - but this was the theme of another book.

Investigation of the impact of simulated commercial centrifugation and microfiltration conditions on levels of Mycobacterium avium subsp. paratuberculosis in milk

The potential for physical removal of Mycobacterium avium ssp. paratuberculosis (M. paratuberculosis) from milk by centrifugation and microfiltration was investigated by simulating commercial processing conditions in the laboratory by means of a microcentrifuge and syringe filters, respectively. Results indicated that both centrifugation of preheated milk (60 degrees C) at 7000 x g for 10 s, and microfiltration through a filter of pore size 1.2 mu m, were capable of removing up to 95-99.9% of M. paratuberculosis cells from spiked whole milk and Middlebrook 7H9 broth suspensions, respectively. Centrifugation and microfiltration may therefore have potential application within the dairy industry as pretreatments to reduce M. paratuberculosis contamination of raw milk.

Inactivation of Mycobacterium avium subsp. paratuberculosis in milk during commercial pasteurisation

Four studies have been published relating to the inactivation of Mycobacterium avium subsp. paratuberculosis (Map) by commercial HTST pasteurization. Three of these were large surveys of commercially pasteurized milk at processing/retail level in the UK and Ontario, Canada, and the fourth a pasteurization study involving naturally infected milk and commercial-scale pasteurizing plant. Evidence that Map is capable of surviving commercial pasteurization was obtained in two of the studies: viable Map was cultured from 50 ml aliquots of commercially pasteurized milk after decontamination with 0.75% cetylpyridinium chloride for 5 h and then culture on Herrold's egg-yolk medium without antibiotics. In both studies culture did not commence until 24-72 h post-pasteurization and samples were stored at 4 degrees C in the interim period. In the other two milk surveys smaller volumes of milk were tested (1-5 ml and 15 ml) and no firm evidence of surviving Map was obtained. The three milk surveys differed in other respects - chemical decontamination, culture media used and use of antibiotics. Recent findings suggest that sub-lethally heat-injured Map in pasteurized milk have the potential to recover viability if stored at 4 degrees C for 48 h between heating and testing.

Commercial oyster stocks as a potential source of larvae in the regeneration of Ostrea edulis in Strangford Lough, Northern Ireland.

Ostrea edulis was extremely rare in the wild in Strangford Lough from the early 1900s until renewed spatfall was observed at a number of sites in the 1990s. A monitoring programme was undertaken to investigate the presence and distribution of planktonic oyster larvae at nine sites around the lough between June and September in 1997 and 1998 as a precursor to studies of spatfall patterns. Larval densities at sites in the northern basin of the lough were significantly higher than those in the southern basin where larvae were lacking or in low numbers. Densities and sizes of oyster larvae showed significant temporal variation suggesting pulsed larval release. Larval densities also showed significant spatial variation with higher densities at sites closer to commercial stocks pointing to these as the main source of oyster larvae. This hypothesis was supported during a larval flux study over a complete tidal cycle which indicated a 90% net tidal movement of O. edulis larvae from the entrance of the bay where commercial stocks were held to the main body of the lough. Thus the maintenance of dense commercial stocks of flat oysters may provide the key to the redevelopment of native oyster beds in Strangford Lough and elsewhere by providing an initial broodstock nucleus from which larvae can be exported.

Correspondence between continuous-variable and discrete quantum systems of arbitrary dimensions

We establish a mapping between a continuous-variable (CV) quantum system and a discrete quantum system of arbitrary dimension. This opens up the general possibility to perform any quantum information task with a CV system as if it were a discrete system. The Einstein-Podolsky-Rosen state is mapped onto the maximally entangled state in any finite-dimensional Hilbert space and thus can be considered as a universal resource of entanglement. An explicit example of the map and a proposal for its experimental realization are discussed.
