Computer program for calculation of oxygen uptake

A description and operational precedures are presented for a computer program, written in Super Basic, that calculates oxygen uptake, carbon dioxide production, and related ventilation parameters. Program features include: (1) the option of entering slope and intercept values of calibration curves for the O2 and CO2 and analyzers; (2) calculation of expired water vapor pressure; and (3) the option of entering inspured O2 and CO2 concentrations. The program is easily adaptable for programmable laboratory calculators

Light airplane crash tests at three roll angles

Three similar twin engine general aviation airplanes were crash tested at the Langley impact dynamics research facility at 27 m/sec and at nominal roll angles of 0 deg, -15 deg, and -30 deg. Other flight parameters were held constant. The test facility, instrumentation, test specimens, and test method are briefly described. Structural damage and accelerometer data for each of the three impact conditions are presented and discussed

Light airplane crash tests at three flight-path angles

Three similar twin engine general aviation airplane specimens were crash tested at Langley impact dynamics research facility at 27 m/sec and at flight-path angles of -15 deg, -30 deg, and -45 deg. Other flight parameters were held constant. The test facility, instrumentation, test specimens, and test method are briefly described. Structural damage and accelerometer data for each of the three impact conditions are presented and discussed

Crash tests of three identical low-wing single-engine airplane

Three identical four place, low wing single engine airplane specimens with nominal masses of 1043 kg were crash tested under controlled free flight conditions. The tests were conducted at the same nominal velocity of 25 m/sec along the flight path. Two airplanes were crashed on a concrete surface (at 10 and 30 deg pitch angles), and one was crashed on soil (at a -30 deg pitch angle). The three tests revealed that the specimen in the -30 deg test on soil sustained massive structural damage in the engine compartment and fire wall. Also, the highest longitudinal cabin floor accelerations occurred in this test. Severe damage, but of lesser magnitude, occurred in the -30 deg test on concrete. The highest normal cabin floor accelerations occurred in this test. The least structural damage and lowest accelerations occurred in the 10 deg test on concrete

Intra-household differentials in women's status : household function and focus as determinants of children's illness management and care in rural Mali

In West Africa, health-seeking behaviour can be better understood by assessing how women differ from each other, rather than how they differ from men, in terms of their socioeconomic and political power within the domestic environment. Anthropological and demographic data were collected among rural Malian Fulani and Dogon populations who possess similar health beliefs and who live in the same ecological area. However, real differences between the two ethnic groups were reflected in variations in maternal status defined according to women’s support and/or autonomy in their households. When a child becomes sick, status obligations result in limited degrees of co-operation between marital female relatives. By contrast, on a day-to-day basis such assistance is rarely forthcoming and women rely on their own unmarried daughters or on external kin networks for surrogate child care. It is concluded that variations in health behaviour and mortality outcomes within these populations reflect not simply ‘ethnic’ differences in beliefs or culture, but rather real differences in mothers’ social positions within their family environments and in their access to household resources for children’s treatment and care

Salicylic Acid Response to Simulated Herbivory in Geographically Distinct T. heterophylla and H. discolor Populations

It is commonly known that plants may produce salicylic acid as a chemical defense response to wounding, although the phenomenon has usually been observed with regard to insect herbivory. Stem and leaf tissue of two species, Tsuga heterophylla and Holodiscus discolor, which are often eaten by deer, were extracted in methanol and analyzed by HPLC to quantify salicylic acid concentration in experimentally wounded or control samples. No salicylic acid response was detectable in T. heterophylla, suggesting it is a less useful candidate species for future study. Some but not all H. discolorsamples had a measurable salicylic acid response, which raises further questions about why only some samples produced detectable amounts of salicylic acid in response to the same simulated herbivory wound. However, it also establishes that H. discolor produces salicylic acid in response to wounding under some circumstances, thereby marking H. discolor as a possible species for further study. Understanding how chemical responses form in response to large mammal grazing may provide insight into how humans indirectly affect plants and their interactions with herbivores, which could have applications for public lands or conservation efforts. An appendix includes the transcript of the presentation of this project at the 2021 SPU Honors Research Symposium, as part of the panel “Considering Research as Ethical and Inclusive Storytelling.
