Control Study

OBJECTIVE:To compare cases of tuberculosis (TB) diagnosed among aboriginal persons with a random sample of nonaboriginal persons diagnosed with TB, and evaluate the trends in rates of disease between both groups during the same period.DESIGN:A case-control study.SETTING:A provincial TB control program.PATIENTS AND METHODS:All patients with TB diagnosed among aboriginal persons in British Columbia between 1992 and 1996 were compared with control patients diagnosed during the same period. For each patient a control patient was identified.INTERVENTION:The demographic details, type of disease, bacteriology, risk factors for TB, therapy received as well as mode of administration were documented. The number of contacts identified for each patient as well as the number of patients completing chemoprophylaxis were identified. The rates of disease during the same period were also documented.RESULTS:During the study, 202 patients with TB were diagnosed among aboriginal persons and 201 controls were chosen. Apart from age at diagnosis (35.1±20 years versus 45.7±19.7), differences in the prevalence of lymphadenopathy (5.9% versus 16.4%, P=0.0008) and pleural disease (21.3% versus 16.4%, P=0.00008), there were no differences in presentation between aboriginal and nonaboriginal people. Aboriginal people were more likely to have a  history of contact with a patient with TB (53% versus 17.9%, PÃ0.05), to have received directly observed therapy (55% versus 33.8%, P=0.00002) and to have contacts who were purified protein derivative (PPD) positive (4±9 versus 2±3, P=0.002). These contacts were more likely to start isoniazid (2±3 versus 1±1, P=0.002). Overall, there was a significant decline in rates of TB among aboriginal persons compared with the general population, but there was a small increase in rates among all subjects in the final year of the study.CONCLUSIONS:In the present study, significant variations in rates of TB among different population groups in British Columbia were found. During the study period, there was a greater decline in the rates of TB among aboriginal persons. A greater use of directly observed therapy and greater use of chemoprophylaxis occurred among aboriginal persons, which may have contributed to this decline, or alternatively, it simply reflects the natural evolution of the TB epidemic.

AbstractIn western Canada, three wax-infesting moth species are serious pests of honey bee products, Vitula edmandsae serratilineella Ragonot, Achroia grisella (F.), and Plodia interpunctella (Hübner). The latter two species are found only in the Fraser Valley of British Columbia, while the driedfruit moth (sometimes called the bumble bee wax moth), V. edmandsae, is found throughout western Canada.Three female-produced pheromone components of V. edmandsae were identified as (Z,E)-9,12-tetradecadien-1-ol, (Z)-9-tetradecen-1-ol, and (Z)-11-hexadecen-1-ol, and field tested. Pheromone baits were used in traps outdoors and in bee equipment storage facilities in the Fraser and Okanagan valleys of British Columbia. The peak indoor trapping period occurred during May in the Okanagan Valley, while catches in indoor traps in the Fraser Valley were negligible throughout the entire trapping period. Catches in outdoor traps peaked during July in both regions. Traps baited with (Z,E)-9,12-tetradecadien-1-ol, alone or in binary combination with (Z)-11-hexadecen-1-ol, were significantly more attractive to male V. edmandsae than all other treatments tested. At one apiary, cumulative moth catch from a trap line 1.0 m from hives was significantly greater than that from a trap line 4.5 m away. The results suggest that a pheromone-based monitoring and control program for V. edmandsae is feasible.

Predator-prey systems are complex and attempts to manage them to benefit woodland caribou populations have generated mixed results. Despite limited success, calls for wolf control continue because of the urgent need to reverse the decline of woodland caribou populations, and because there are so few management options available that have the potential to demonstrate immediate benefits. I present the results of a policy analysis that reviews the potential role of wolf control within the ecological, social and political context of northeast British Columbia (BC). The scale and scope of a wolf control program is ultimately limited by the economic and ethical support of the public, while the program’s effectiveness is governed by the conditional dependencies among the major factors effecting woodland caribou declines. The policy analysis suggests that the contribution of wolf control programs to caribou conservation efforts in northeast BC will be limited, but that significant uncertainties in the causal pathways resulting in caribou population declines limit our ability to propose alternative management policies that have a high confidence of success.

TASK8 was designed as an electron microprobe control program with maximum flexibility and versatility, lending itself to a wide variety of applications. While using TASKS in the microprobe laboratory of the Los Alamos National Laboratory, we decided to incorporate the capability of using subroutines which perform specific end-member calculations for nearly any type of mineral phase that might be analyzed in the laboratory. This procedure minimizes the need for post-processing of the data to perform such calculations as element ratios or end-member or formula proportions. It also allows real time assessment of each data point.The use of unique “mineral codes” to specify the list of elements to be measured and the type of calculation to perform on the results was first used in the microprobe laboratory at the California Institute of Technology to optimize the analysis of mineral phases. This approach was used to create a series of subroutines in TASK8 which are called by a three letter code.

In-situ experiments conducted within a transmission electron microscope provide the operator a unique opportunity to directly observe microstructural phenomena, such as phase transformations and dislocation-precipitate interactions, “as they happen”. However, in-situ experiments usually require a tremendous amount of experimental preparation beforehand, as well as, during the actual experiment. In most cases the researcher must operate and control several pieces of equipment simultaneously. For example, in in-situ deformation experiments, the researcher may have to not only operate the TEM, but also control the straining holder and possibly some recording system such as a video tape machine. When it comes to in-situ fatigue deformation, the experiments became even more complicated with having to control numerous loading cycles while following the slow crack growth. In this paper we will describe a new method for conducting in-situ fatigue experiments using a camputer-controlled tensile straining holder.The tensile straining holder used with computer-control system was manufactured by Philips for the Philips 300 series microscopes. It was necessary to modify the specimen stage area of this holder to work in the Philips 400 series microscopes because the distance between the optic axis and holder airlock is different than in the Philips 300 series microscopes. However, the program and interfacing can easily be modified to work with any goniometer type straining holder which uses a penrmanent magnet motor.
