Chemical and physical properties of bulk aerosols within four sectors observed during TRACE-P

Chemical and physical aerosol data collected on the DC-8 during TRACE-P were grouped into four sectors based on back trajectories. The four sectors represent long-range transport from the west (WSW), regional circulation over the western Pacific and Southeast Asia (SE Asia), polluted transport from northern Asia with substantial sea salt at low altitudes (NNW) and a substantial amount of dust (Channel). WSW has generally low mixing ratios at both middle and high altitudes, with the bulk of the aerosol mass due to non-sea-salt water-soluble inorganic species. Low altitude SE Asia also has low mean mixing ratios in general, with the majority of the aerosol mass comprised of non-sea-salts, however, soot is also relatively important in this region. NNW had the highest mean sea salt mixing ratios, with the aerosol mass at low altitudes (\u3c2 km) evenly divided between sea salts, non-sea-salts, and dust. The highest mean mixing ratios of water-soluble ions and soot were observed at the lowest altitudes (\u3c2 km) in the Channel sector. The bulk of the aerosol mass exported from Asia emanates from Channel at both low and midaltitudes, due to the prevalence of dust compared to other sectors. Number densities show enhanced fine particles for Channel and NNW, while their volume distributions are enhanced due to sea salt and dust. Low-altitude Channel exhibits the highest condensation nuclei (CN) number densities along with enhanced scattering coefficients, compared to the other sectors. At midaltitudes (2–7 km), low mean CN number densities coupled with a high proportion of nonvolatile particles (≥65%) observed in polluted sectors (Channel and NNW) are attributed to wet scavenging which removes hygroscopic CN particles. Low single scatter albedo in SE Asia reflects enhanced soot

Transforming CyberSecurity R&D within the Department of Energy: Getting Ahead of The Threat

This report outlines a preliminary response from DOE researchers to the following three questions: a) what are the key priorities w.r.t. cybersecurity R&D over the next decade? b) what would we recommend, in terms of a program, to address those priorities c) how would a DOE Office of Science program in this area complement other cybersecurity R&D initiatives such as NSF's or other agency programs

Long term survival after coronary endarterectomy in patients undergoing combined coronary and valvular surgery – a fifteen year experience

<p>Abstract</p> <p>Background</p> <p>Coronary Endarterectomy (CE) in patients undergoing coronary artery bypass graft (CABG) surgery has been shown to be beneficial in those with diffuse coronary artery disease. There are no published data on its role and benefit in patients undergoing more complex operations. We present our experience with CE in patients undergoing valve surgery with concomitant CABG.</p> <p>Materials and methods</p> <p>Between 1989 and 2003, 237 patients underwent CABG with valve surgery under a single surgeon at our institution. Of these, 41 patients needed CE. Data was retrospectively obtained from hospital records and database. Further follow-up was obtained by telephone interview. All variables were analyzed by univariate analysis for significant factors relating to hospital mortality. Morbidity and long term survival was also studied. There were 29 males and 12 females with a mean age of 67.4 ± 8.1 and body mass index of 26.3 ± 3.3. Their mean euroscore was 7.6 ± 3.2 and the log euro score was 12.2 ± 16.1.</p> <p>Results</p> <p>Thirty-two patients were discharged from the intensive therapy unit within 48 hours after surgery. Average hospital stay was 12.7 ± 10.43 days. Thirty day mortality was 9.8%. Six late deaths occurred during the 14 year follow up. Ten year survival was 57.2% (95% CL 37.8%–86.6%). Three of the survivors had Class II symptoms, with one requiring nitrates. None required further percutaneous or surgical intervention. We compared the result with the available mortality figure from the SCTS database.</p> <p>Conclusion</p> <p>Compared to the SCTS database for these patients, we have observed that CE does not increase the mortality in combined procedures. By accomplishing revascularization in areas deemed ungraftable, we have shown an added survival benefit in this group of patients.</p

Yalanji-Warranga Kaban: Yalanji people of the rainforest fire management book

The tropical rainforest, beaches, reefs, and mountain ranges stretching along the coast between Mossman and the Annan River are the homelands of Eastern Yalanji people (bama). We have been here since the beginning in the dreaming. Stories of the lives of past generations of Eastern Yalanji bama are held in every mangrove inlet, in the roaring torrents and giant mountain boulders, and in the silent sliding streams. We Yalanji bama are still here today and hold strongly to our Law, culture and language in building for the future. "Kulu-Yanlanji" literally means speakers of Yalanji language. There are several dialects within this language. Yalanji bama are related to each other and to different parts of out lands through out customary law. Only those people with the right connections to a particular place can speak for that country, for that place. The tract of country belonging to our particular family group is known as our "clan estate". To know your role and your place in Yalanji society, you must know your country, your clan estate and your kin

Student Preferences in Learning Spaces and Classrooms

The primary intention of this study was to see how students at the University of British Columbia (UBC) prioritize various amenities in the classroom versus in study spaces. Data was collected from a sample of 63 UBC students. An online Qualtrics survey was distributed, allowing students to rank their preferences for basic learning space amenities in order from most important to least important. Our list of amenities was assembled in collaboration with the University client, Steven Lee. The specific focus of our analysis is on the accessibility of electrical outlets in different learning environments on campus. Other amenities were included for consideration in the survey, but were not relevant to our specific analysis. Importantly, we wanted to investigate how students’ preferences varied depending on two main factors: whether the room is a classroom or a study space, and also whether the respondents live on- or off-campus. Further, we assessed how the length of an off-campus student’s daily commute impacts their preference ranking. Results indicate that students value electrical outlet accessibility more in study spaces than they do in classrooms, in a statistically significant way. The discrepancy in preference for electrical outlets between on-campus and off-campus students was found to not be statistically significant; though there was a small negative relationship between length of commute and preference for outlets. Results indicate that electrical outlet accessibility in academic spaces on campus is of crucial importance to all UBC students.
