A young couple faced with the decision to buy an apartment in the areas close to their work, that would have cost them twice as much for a third of the size of this house, were drawn towards the solution of living a little further away and being linked to the smaller population centres of La Garita and Atenas instead. This location puts in relevance the constructive traditions of these old towns and their strong relationship with their rural and natural borders. In this sense, the house is considered an extension of the shade of the trees that border the ravine, which also defines the limit of the terrain. Stones, reeds and a small bridge are used as well, associated with the bodies of water of the location.Save this picture!© Roberto D´AmbrosioSave this picture!Site PlanSave this picture!© Roberto D´AmbrosioAlso, ornamental clay bricks that appear in traditional houses and walls are used, in order to make a neutral facade linked to the local infrastructure, in opposition to other new houses of the residential area, which tend to compete with each other in flamboyance. This wall is used to mitigate the elongated orientation to the east (in a village with high temperatures) indisputable by the geometry of the terrain. The wall is also separated from the house to create a mattress of air and water in between (fed by rainwater collectors).Save this picture!© Roberto D´AmbrosioThe roof is placed on the walls as a single plane manipulated according to clear folding rules, which configures the space in its upper plane in a direct and uncomplicated manner. The separation between the top of the walls and the ceiling is left open in a similar way to the interstitial space of the vernacular houses where the children used to play. In this area associated with privacy, security and recreation, some spaces for personal use are created.Save this picture!© Roberto D´AmbrosioSave this picture!Axonometric ViewOn the west side of the house that faces a barrier of trees, the roof is elevated in order to reveal a view of the treetops, but when necessary, reed gates are used as an organic mass that opposes the sun rays that manage to filter through the trees. When opening these gates completely, the house is integrated with the small terrace, the patio and the ravine.Save this picture!© Roberto D´AmbrosioIn summary, this house achieves to meet the expectations of a Costa Rican middle-class couple largely affected by the discrepancy between their aspirations and their economic capacity, creating more quality space with less material and lower costs.Save this picture!© Roberto D´AmbrosioProject gallerySee allShow lessQuetzal Bar / PartisansSelected ProjectsGrid House / Studio Guilherme TorresSelected Projects Share “COPY” CopyHouses•La Garita, Costa Rica CopyAbout this officeArkosisOfficeFollow#TagsProjectsBuilt ProjectsSelected ProjectsResidential ArchitectureHousesLa GaritaCosta RicaPublished on May 02, 2019Cite: “La Garita House / Arkosis” [Casa en La Garita / Arkosis] 02 May 2019.

Ground‐based observations of VLF waves as a proxy for satellite observations: Development of models including the influence of solar illumination and geomagnetic disturbance levels

first_imgGround VLF observations have often been used to infer VLF activity in the magnetosphere, however, they are not an unbiased measure of activity at satellite altitudes due to transionospheric absorption and subionospheric attenuation. We propose several empirical models that control for these effects. VLF power spectral density (PSD) from the VLF/ELF Logger Experiment (VELOX, L=4.6, Halley, Antarctica) is used to predict DEMETER low Earth orbit VLF PSD. Validation correlations of these models are as high as 0.764, thus ground VLF receivers spaced around the Earth could provide complete coverage of outer radiation belt lower band chorus over the latitudinal limits of this model (±45‐75°). Correlations of four frequency bands (centered at 0.5 kHz, 1.0 kHz, 2.0 kHz, and 4.25 kHz) are compared. The simple linear correlation between ground and satellite VLF PSD in the 1.0 kHz channel was 0.606 (at dawn). A cubic model resulted in higher correlation (0.638). VLF penetration to the ground is reduced by ionospheric absorption during solar illumination and by disruption of ducting field lines during disturbed conditions. Subionospheric attenuation also reduces VLF observations from distant field lines. Addition of these covariates improved predictions. Both solar illumination and disturbed conditions reduced ground observation of VLF PSD, with higher power waves penetrating to the ground proportionately less than lower power waves. The effect of illumination in reducing wave penetration was more pronounced at higher frequency (4.25 kHz), with the effect at a mid‐range frequency (2.0 kHz) falling between these two extremes.last_img read more

Leonard Nash, 95

first_imgAt a Meeting of the Faculty of Arts and Sciences on May 1, 2018, the following tribute to the life and service of the late Leonard Kollender Nash was placed upon the permanent records of the Faculty.“He doesn’t really lecture — he dances and cajoles.” When Leonard K. Nash, William R. Kenan, Jr., Professor of Chemistry Emeritus, died at age 95, droves of former students, across decades and countries, lauded his rare ability to inspire and enchant. A 1977 Harvard Crimson “Confi Guide” named him one of the “top ten lecturers teaching in the College,” a title that fails to capture the eccentric, passionate, and benevolent flair that stimulated generations of students to pursue chemistry.Leonard enrolled in Harvard College in 1935, at the tender age of 16. After his undergraduate studies, he continued on at Harvard to earn his doctorate in analytical chemistry in 1944. He then taught briefly at the University of Illinois before returning to Harvard in 1948 as a faculty member. Here, he conducted research in thermodynamics and statistical mechanics, chaired the department from 1971 to 1974, and converted countless students to a love of chemistry.Leonard commanded entry-level classes with contagious joy. Once, he swallowed a beaker of what appeared to be fresh blood, perhaps to capture the attention of a lethargic freshman class or demonstrate an obscure scientific point. Full of relentless energy, he would run across his amphitheater to set up his own slides or respond to a student’s incorrect answer with a playful jab. He often lingered after lectures to answer questions, held inexhaustible office hours for those struggling to understand, and invented memorable acts to demonstrate difficult concepts. He was a magnanimous performer.Leonard attracted students from other disciplines and careers to pursue chemistry instead. Martin Karplus was one such student. A future Nobel Prize winner, he credits Nash for influencing his decision to study the “biology of people” rather than become a doctor. Another distinguished chemist, Kent R. Wilson, also cited Leonard for his decision to switch from political science to chemistry. His 1999 article “Summing Up” (Journal of Physical Chemistry) relates the moment when, during a lab contest, Leonard enraptured him.  Wilson identified eight of ten unmarked liquid solutions. Unable to differentiate NaCl from KCl, he tasted them. Leonard was not impressed. Though Wilson’s method produced the correct answers, Leonard reopened the competition and a second student eventually identified all solutions. During the next class, Leonardplaced the contest prize, a copy of the “Handbook of Chemistry and Physics,” upright on the lab bench. He said that he had a difficult problem, that Wilson had quickly gotten the right answer, but by a potentially dangerous method, and that “Smith” had gotten the correct answer, but had taken an hour longer and required hints. What to do about the prize? Surprising us all, he reached back for the fire axe and swung it to neatly split the book in two, handing half to each of us. I was crestfallen, my prize ruined. … Then, to perfect effect, after waiting just the right amount of time, he reached under the lab bench and took out two new copies of the “Handbook.” He had captured me. I switched my major to chemistry and physics.During his four decades of teaching at Harvard, Leonard hosted lunches at Chinese restaurants, offered to fix the damaged roof of a former student’s new home, and traded an hour of tutoring for an hour of babysitting so his wife, Ava, could enjoy Harvard Square. Prized students learned his code name “Swordfish” granted them access to Leonard through his home phone, long after both class and office hours ended. “Swordfish” even held regular meetings with a dedicated group of students — including Martin Karplus and future Stanford Law Professor John Kaplan — to address questions far beyond those covered in his Elementary Chemistry course. Leonard gave his time and mind generously and delighted in the well-being and success of those around him.Leonard’s rare talent for teaching did not eclipse his scientific achievements. He worked on the Manhattan Project during World War II and helped elucidate thermodynamics. He also gravitated to the philosophy of science and published “The Nature of the Natural Sciences”, which refuted scientific revolutions and promoted an evolutionary epistemology of science. In close partnership with J. B. Conant — chemist and President of Harvard from 1933 to 1953 — and Thomas Kuhn, Leonard developed and then championed a course in Harvard’s nascent History of Science program. The course, which examined obsolete theories of science (geocentric, phlogiston, etc.) against their replacements, stimulated not only the students but its three pioneering leaders as well. In fact, Kuhn later dedicated his first book to Nash “for a vehement collaboration.”  The course propelled Leonard’s future passion for metascience, philosophy, and the social dimensions of science.Leonard’s scientific and philosophical research and publications enhanced his dedication to science education. He authored two successful textbooks that remain in print today: “Elements of Statistical Thermodynamics” and “Elements of Chemical Thermodynamics.” A review of his textbook “ChemThermo” from the Journal of Chemical Education praised his ability to demonstrate “‘advanced’ but fundamental concepts in a form accessible to the first-year student.” Though today’s first-year students miss the in-person splendor of his classes, they can still benefit from Leonard’s ability to synthesize the most challenging concepts for fledgling chemists.An only child of Adolph and Carol Nash, Leonard was raised in New York City before he found a home near Cambridge, Mass. Ava (née Byer), his wife of 63 years, balanced Leonard’s energy with calm humor. Before her death, Ava developed dementia and Leonard, with a rare expression of sadness, grieved for the only other person who knew his memories. It was not meaningful, he remarked, to remember alone. With memories of extensive European travel, Maine canoe trips, lunches with fine red wines (until he lost his sense of smell in his eighties), Zipcars and Restaurant Week, Chinese food and balancing equations about pressure and volume, he had too much joy to lose. And Leonard’s legacy lives on through his children and the many students — now professors, innovators, and pioneers — he awed and inspired.Respectfully submitted,Daniel KahneCharles LieberDudley Herschbach, Chairlast_img read more
