Boron nanobelts grown under intensive ion bombardment

High-quality α-tetragonal crystalline boronnanobelts with [001] growth axis were synthesized using a novel method combining e-beam evaporation and plasma ion bombardment techniques. Intensive ion bombardment of the growingboronnanobelts at a high substrate temperature (∼1200°C) was found to be effective in increasing the atomic density, reducing the crystal disorder, and improving the yield of the nanobelts.This work was supported by the Australian Research Council ARC

Set and Drift: The Role of the Marine Corps over the next Decade

The direction that the U.S Marine Corps takes over the next fifty years will depend largely upon the politico-military role of the United States in the post-Cold War era. The Marine Corps has never existed in a purely military vacuum, and it is probable that because of its special role in rapid deployment and amphibious operations it will continue to serve as the primary agent of U.S. power projection throughout an increasingly unstable globe. The traditionally close relationship between the Marine Corps and the Department of State can be expected to continue, mainly because the Marines are capable of providing rapid and credible military support for the diplomatic and strategic objectives of U.S. foreign policy

A STUDY OF TYPES OF RESPIRATORY MOVEMENTS

1. Children of the two sexes differ very little in the character of their respiratory movements. 2. Between girls and women and boys and men there is little or no difference in respiratory type. 3. Childbearing does not permanently affect respiration. 4. The natural type of respiration, for both sexes is one in which the movement is fairly equally balanced between chest and abdomen, the abdominal being somewhat in excess. 5. In typical unconstricted individuals the chest contributes about the same bulk of air as does the abdomen. 6. Constricting dress causes preponderance of thoracic movement in ratio to its restriction of abdominal movement and to the sensitiveness of the nervous co-ordination

A comparison of A-level performance in economics and business studies: how much more difficult is economics?

This paper uses ALIS data to compare academic performance in two subjects often viewed as relatively close substitutes for one another at A-level. The important role of GCSE achievement is confirmed for both subjects. There is evidence of strong gender effects and variation in outcomes across Examination Boards. A counterfactual exercise suggests that if the sample of Business Studies candidates had studied Economics nearly 40% of those who obtained a grade C or better in the former subject would not have done so in the latter. The opposite exercise uggests that 12% more Economics candidates would have achieved a grade C or better if they had taken Business Studies. In order to render a Business Studies A-level grade comparable to an Economics one in terms of relative difficulty, we estimate that a downward adjustment of 1.5 UCAS points should be applied to the former subject. This adjustment is lower than that suggested by correction factors based on conventional subject pair analysis for these two subjects

W. S. Merwin: 02-29-1968

Merwin discusses his changing poetic style, saying that he never stays excited about any style for very long, and that he now wants to write about direct experiences. He talks about the gradual abandonment of punctuation in his poems and the reliance on the language of a poem that a lack of punctuation highlights. Merwin also talks about the inability to shut the politics of the day out of his poems, and the mutual revulsion between art and topicality.https://digitalcommons.brockport.edu/writers_videos/1031/thumbnail.jp
