Burger studies

Glaser and Burger studied the biosynthesis of teichoic acids with particulate preparations from Bacillus licheniformis (ATGC 9945) and B. subtilis (NCTG 3610). They found that these preparations catalyze the synthesis of poly(glycerol phosphate) according to the reaction... 

Chemical shifts for some representatives of the less common class of A -pyrazolines are shown in Table 13. These cyclic enehydrazines are also probably puckered (69) however, no X-ray determination nor conformational study has been carried out to solve this problem. Compound (70) is representative of the rare N(l)-unsubstituted A -pyrazolines prepared by Burger et al. (79T389). 

The Burgers vectors, glide plane and ine direction of the dislocations studied in this paper are given in table 1. Included in this table are also the results for the Peierls stresses as calculated here and, for comparison, those determined previously [6] with a different interatomic interaction model [16]. In the following we give for each of the three Burgers vectors under consideration a short description of the results. 

Hill et al. [117] extended the lower end of the temperature range studied (383—503 K) to investigate, in detail, the kinetic characteristics of the acceleratory period, which did not accurately obey eqn. (9). Behaviour varied with sample preparation. For recrystallized material, most of the acceleratory period showed an exponential increase of reaction rate with time (E = 155 kJ mole-1). Values of E for reaction at an interface and for nucleation within the crystal were 130 and 210 kJ mole-1, respectively. It was concluded that potential nuclei are not randomly distributed but are separated by a characteristic minimum distance, related to the Burgers vector of the dislocations present. Below 423 K, nucleation within crystals is very slow compared with decomposition at surfaces. Rate measurements are discussed with reference to absolute reaction rate theory.

Both the development and application of bioindicators present a number of methodological considerations. One key requirement is to relate dose/effects studies in the laboratory, and residne levels/efifects studies in the field. For many years, these stndies were condncted by different groups of scientists, and the cotmections were not made (Eisler 1987). Ideally, we should use bioindicators where there are clear links between exposnre levels, tissue levels, and effects (Burger and Gochfeld 2003). The most nseful bioindicators of those we suggest are those where the cotmections have been clearly made.

A concise approach for the analysis of isotropic scattering curves of spherical and cylindrical particles with a radial density profile has been developed by Burger [207], In practice it is useful for the study of latices and vesicles in solution. 

More simple solutions are found for special cases. Already in 1933 Kratky [248] has presented a method for the case in which the observed orientation distribution has its maximum on the equator. In 1979 the problem treated by Kratky has been revisited by Leadbetter and Norris [254], They present a different solution which is frequently applied in studies of liquid-crystalline polymers. Burger and Ru-land [255] pinpoint the error in the deduction of Leadbetter and... 

A study carried out in Ireland which also compared oxidative stability and a-tocopherol levels in organic, free-range and conventional breast meat burgers from France, Ireland and the UK showed significant and greater variability between different samples from the same production system, than between production systems. They concluded that oxidative stability and a-tocopherol...

Studies have shown that it s not that simple. In one, registered dieticians couldn t come up with accurate estimates of the calories found in (30) certain fast foods. Who would have guessed that a milk shake, which sounds pretty healthy (it does contain milk, after all) has more calories than three McDonald s cheeseburgers Or that one chain s chicken breast sandwich, another better-sounding alternative to a burger, contains more than half a day s calories and twice the recommended daily (33) amount of sodium Even a fast-food coffee drink, without a doughnut to go with it, has almost half the calories needed in a day. 

A detailed study of the problems caused by starvation, the response to ref ceding and the best methods for refeeding was carried out by an international team of medical and nutritional experts whose Hndings were published in 1948 by The Netherlands Government (Burger et al., 1948).
