Geophysical Computer Program 11

Program HYPOERR evaluates the performance of a small network of arbitrary seismic arrays in determining coordinates and times of seismic events. A linearized inversion following the method of Uhrhammer (1980)is performed for a layered velocity structure by determining the eigenvalues and eigenvectors of the partial derivatives of travel time for P and/or S phases with respect to hypocenter position and origin time for each station in the array. A series of covariance matrices is then obtained to evaluate statistical errors for a specified grid of hypocenter locations at any given depth. Contour plots can then be made of the matrix elements by using standard contouring software. Examples are given for ( 1) the case of a hypothetical quadrapartite array and (2) an actual eight-station ocean-bottom seismometer array deployed around the 95.5° W. Galapagos propagating-rift zone

Hawaii Geothermal Resource Assessment Program, direct heat resource assessment interim report, February 1, 1979 to January 31, 1980

During 1979 reconnaissance field surveys were conducted on the islands of Hawaii, Maui, and Oahu with the objective of confirming groundwater chemical data and geophysical data compiled during the preliminary regional assessment of Phase I of the Direct Heat Resource Assessment Program. The exploration techniques applied include (1) groundwater chemistry, (2) mercury-radon surveys, (3) isotopic composition of groundwaters, (4) time domain electromagnetics, and (5) Schlumberger resistivity surveys. The results of these surveys can be classified as follows: (1) Hawaii: Kailua-Kona, strong geochemical anomalies; Kawaihae, strong geophysical anomalies, moderate to strong geochemical anomalies; Hualalai northwest rift, weak geochemical and moderate geophysical anomalies; South Point, moderate to weak geophysical anomalies; Hualalai southeast rift, weak geophysical anomalies; Keaau, weak geophysical and geochemical anomalies; (2) Maui: Haiku-Paia, strong geochemical anomalies; Olowalu-Ukamehame canyons, moderate to strong geochemical and geophysical anomalies; Lahaina, weak geochemical and geophysical anomalies; (3) Oahu: Lualualei, moderate to strong geochemical and geophysical anomalies; Waimanalo-Maunawili, insufficient data.Work performed under Contract DE-AS03-ET7927023

Preliminary geothermal assessment surveys for the State of Hawaii

Transactions, Geothermal Resources Council, Volume 4"The Geothermal Resource Assessment Program of the Hawaii Institute of Geophysics has conducted a series of geochemical and geophysical surveys in ten separate locations within the State of Hawaii in an effort to identify and assess potential geothermal areas throughout the state. The techniques applied include groundwater chemistry and temperatures, soil mercury surveys, ground radon emanometry, time-domain electromagnetic surveys and Schlumberger resistivity soundings. Although geochemical and geophysical anomalies were identified in nearly all the survey sites, those areas which show most promise, based on presently available data, for a geothermal resource are as follows: Puna, Kailua Kona, and Kawaihae on the island of Hawaii; Haiku-Paia and Olowalu-Ukumehame canyons on Maui; and Lualualei Valley on Oahu. Further surveys are planned for most of these areas in order to further define the nature of the thermal resource present.

Concepts and practices of digital virtual consumption

Despite the popularity of online spaces that simulate aspects of consumption?like experiences (online virtual worlds, video games and interactive functions on online retailers) conceptual tools that aim to comprehend such consumer practices are yet to emerge. In an effort to better understand them this paper puts forward a taxonomy that may help us capture emerging consumer behavior in the digital virtual terrain in relation to virtual and material consumption. This may be read as a fluid template that considers the movement between what resides in consumer imaginations as ideal or virtual, its actualization in material and now also digital virtual spaces. We then offer examples of the practices that are emerging, specifically the increase in imaginative resources that interactive media provide; practices that actualize probable, everyday commodities and experiences in the digital virtual and practices that actualize fantastic commodities and experiences in the digital virtual. Finally, we discuss the potential for these to produce new consumer subjectivities and new markets, and as a result we conclude with a discussion of the implications of such developments for consumer cultures, noting the potential for both liberatory/celebratory and critical discourse as well as avenues for future researc

Treatable traits in the NOVELTY study

CorrigendumVolume 27, Issue 12, Respirology, pages: 1095-1095. First Published online: November 6, 2022 10.1111/resp.14406International audienceAsthma and chronic obstructive pulmonary disease (COPD) are two prevalent and complex diseases that require personalized management. Although a strategy based on treatable traits (TTs) has been proposed, the prevalence and relationship of TTs to the diagnostic label and disease severity established by the attending physician in a real-world setting are unknown. We assessed how the presence/absence of specific TTs relate to the diagnosis and severity of 'asthma', 'COPD' or 'asthma + COPD'
