ECONOMIC IMPORTANCE OF AGRICULTURE-RELATED INDUSTRY IN MINNESOTA
This report is the third in a series on interindustry and interregional relationships and their implications for the economy of Minnesota and its substate development regions. In this report, the role and importance of agriculture-related industries in Minnesota are discussed. A total of 19 agriculture and 35 food products manufacturing industries are identified as the principal agriculture-related industries in the state and the nation. Their interindustry and interregional (Minnesota and rest-of-nation) linkages are derived for the 1977 calendar year.Community/Rural/Urban Development,
Seroepidemiology of <i>Trichomonas vaginalis</i> in rural women in Zimbabwe and patterns of association with HIV infection
Serological assays using dried blood spots from 5221 women in rural areas of eastern Zimbabwe
were used to assess the epidemiology of Trichomonas vaginalis infection, and its association with
HIV. Antibodies to T. vaginalis and to HIV were detected by enzyme immunoassays. Behavioural
and demographic data were collected by confidential questionnaires. In total, 516 (9.9%) women
were seropositive for T. vaginalis and seroprevalence increased with age among younger women.
Divorced, widowed and single women were more likely to be seropositive. After controlling for
age, seropositivity was significantly associated with being sexually active, having multiple sex
partners, having a partner who had multiple sex partners, and having a new sex partner in the
past year. Seropositivity was associated with a recent history of genital discharge. Overall, 208
(40.3%) T. vaginalis-positive samples were also positive for HIV, compared with 1106 (23.5%)
T. vaginalis-negative samples (age and sex adjusted OR 2.11, 95% CI 1.74–2.55, P<0.001). There
was increased risk for being HIV-positive amongst T. vaginalis-seropositive women regardless of
residence, employment or education. In a logistic regression controlling for common risk factors,
the association remained significant. T. vaginalis-seropositive young women with a history of
genital discharge were much more likely to be HIV-positive than women who were T. vaginalis-seronegative
and had no history of discharge (OR 6.08, 95% CI 2.95–12.53). Although a causal
relationship cannot be assumed, detection and treatment of trichomoniasis may be important in
strategies to reduce HIV transmission through sexually transmitted infection control
Proceedings of the 5th International Symposium on Biological Control of Arthropods
This proceedings contains papers dealing with issues affecting biological control, particularly pertaining to the use of parasitoids and predators as biological control agents. This includes all approaches to biological control: conservation, augmentation, and importation of natural enemy species for the control of arthropod targets, as well as other transversal issues related to its implementation. It has 14 sessions addressing the most relevant and current topics in the field of biological control of arthropods: (i) Accidental introductions of biocontrol agens: positive and negative aspects; (ii) The importance of pre and post release genetics in biological control; (iii) How well do we understand non-target impacts in arthropod biological control; (iv) Regulation and access and benefit sharing policies relevant for classical biological control approaches; (v) The role of native and alien natural enemy diversity in biological control; (vi) Frontiers in forest insect control; (vii) Biocontrol marketplace I; (viii) Weed and arthropod biological control: mutual benefits and challenges; (ix) Maximizing opportunities for biological control in Asia's rapidly changing agro-environments; (x) Biological control based integrated pest management: does it work?; (xi) Exploring the compatibility of arthropod biological control and pesticides: models and data; (xii) Successes and uptake of arthropod biological control in developing countries; (xiii) Socio-economic impacts of biological control; (xiv) Biocontrol marketplace II
Automated Impact Assessment: A New Approach to ISS Payload Operations Anomaly Response
The International Space Station (ISS) Payload Operations and Integration Center (POIC) is undergoing rapid growth as the space station program focuses on science and commercial activities. The ISS is expanding its onboard capabilities to support additional science activities. In parallel, the POIC is expanding the capabilities of our operations tools to support the higher pace of payload activities being executed each week. An effect of these changes is that anomaly resolution has become more challenging. In the event of a real-time system fault, operators are responsible for analyzing telemetry displays, anomaly monitoring tools, documentation, and system models in order to produce failure impacts and recovery strategies. This approach to operations relies on the operator to ingest, process, and analyze information from an array of deterministic sources to provide actionable data on impacted systems and activities. Changing the existing approach of anomaly response is necessary if the ISS community is to succeed in the age of science and commercialization of space. The creation of a tool that captures deterministic technical systems knowledge and integrates existing telemetry, documentation, and planning information will allow the burden of impact assessment to be automated, thereby allowing the operator to focus on non-deterministic tasks, such as recovering failed systems and restoring critical payload operations
Structure and dielectric response in the high ferroelectric Bi(Zn,Ti)O-PbTiO solid solutions
Theoretical {\em ab initio} and experimental methods were used to investigate
the Bi(Zn,Ti)O-(1-)PbTiO (BZT-PT) solid solution. We find that
hybridization between Zn 4 and O 2 orbitals allows the formation of
short, covalent Zn-O bonds, enabling favorable coupling between A-site and
B-site displacements. This leads to large polarization, strong tetragonality
and an elevated ferroelectric to paraelectric phase transition temperature.
nhomogeneities in local structure near the 90 domain boundaries can be
deduced from the asymetric peak broadening in the neutron and x-ray diffraction
spectra. These extrinsic effects make the ferroelectric to paraelectric phase
transition diffuse in BZT-PT solid solutions
INVESTIGATION OF COACH RATINGS OF TECHNIQUE AND FORCE-TIME PROFILES IN ELITE MALE FRONT CRAWL SPRINT SWIMMERS
The purpose of this investigation was to examine the relationship between assisted towing method (ATM) force-time profiles and coach ratings of front crawl technique. Nine elite male swimmers completed the ATM sprint swimming protocol to obtain active drag and propulsion values. Six coaches each rated overall technique from video footage and technique at each of four stroke events (entry, pull, push, and exit) from images captured throughout the ATM trials. Mean coach technique rating scores were then correlated against four performance measures (FINA point score, 100 m performance best time, active drag value and propulsion value). Results demonstrated weak to strong relationships between the ratings and performance variables for each stroke event
