Adobe Acrobat 8: visual quickstart guide
No full textAdobe Acrobat 8 for Windows and Macintosh: Visual QuickStart Guide uses a combination of task-based instruction and strong visuals to teach beginning and intermediate users how to be more productive with Adobe Acrobat. Author John Deubert takes readers step by step through all of the Adobe Acrobat 8 essentials, both basic--creating and viewing electronic documents, streamlining document reviews, using Acrobat's commenting and reviewing tools--and advanced--using digital signatures, creating interactive forms, and protecting sensitive documents. Both beginning users who want a thorough introduction to the topic, and more advanced users looking for a convenient reference will find what they need here in straightforward language, clear steps, and practical tips. By the end of the book, users will be able to smoothly integrate Adobe Acrobat 8 into their workflow
Semiconductor quantum dots devices: Recent advances and application prospects
No full textIn this paper, a brief review will be given on recent advances in semiconductor quantum dots based optoelectronic devices. The focus will be on two major application areas, i.e., telecom devices and high power light sources, where some device examples will be discussed on the current status and for the future prospect
Regulation by low temperature of phytoplankton growth and nutrient uptake in the Southern Ocean
No full textDuring oceanographic cruises in 1996 and 1998, phytoplankton from 15 stations in the southwest Atlantic sector of the Southern Ocean were incubated at ambient temperature and 2 elevated temperatures (ambient plus 3°C, and ambient plus 6°C). Rates of growth, nutrient depletion, 15N-nitrate uptake and nutrient interaction were all studied. Microalgal growth rate showed a strong positive relationship to temperature elevation, indicating ambient temperatures were sub-optimal for the phytoplanktonic community as a whole. Ratios of silicate uptake to chlorophyll a increase were high at ambient temperatures and showed a strong negative relationship with temperature elevation. Nitrate uptake rates, measured by 15N-nitrate incorporation, showed a consistent trend of increased uptake rate at elevated temperature. Specific nitrate-depletion rates, 15N-nitrate uptake rates, and the Ÿ ratio all showed an inverse relationship to increasing ammonium concentration. The results of this study imply that ambient temperature, in addition to direct iron limitation, is important in the maintenance of the high nutrient, low chlorophyll conditions common to the Southern Ocean
