Every year, in the United States and Canada, Thoudands of dollars worth of stored grain is ruined by granary insects, chiefly of three species. These are all well known, and much has been written concerning their habits and the methods by which they can be destroyed. Besides the three very injurious species, the Granary Weevil, the Rice Weevil and the Angoumois Grain Moth, which are responsible for the most of the damage done, there are a great many other kinds of insects which do serious harm to stored grain and various other edible products.

Major Pest

AbstractRhyzopertha dominica (F.) (lesser grain borer, Coleoptera: Bostrichidae) is a major pest of stored grain in the United States, Australia, and most other warm regions of the world. It has rarely been detected in Canadian grain, until recently. To determine the distribution of/R. dominica in western Canada, Lindgren multiple-funnel traps baited with R. dominica aggregation pheromones were placed near grain elevators, feed mills, and farms. Rhyzopertha dominica was found flying outside grain-handling facilities in all Prairie Provinces in 1990 and 1991, with thousands collected in Manitoba, hundreds in Alberta, and less than 100 in Saskatchewan. A few R. dominica were caught in Vancouver and Thunder Bay. None were caught in the traps placed beside two grain elevators in southern Ontario. In Alberta and Saskatchewan, the locations with R. dominica were mainly in the south. In Manitoba, the total number of R. dominica caught at each location was higher in the south than in the north. Rhyzopertha dominica were caught as early as 15 May and as late as 18 September, with the peak numbers for a given location occurring between July and September. No difference in the total number of R. dominica caught per year was found among farms, feed mills, or grain elevators in 1990 or 1991. Sampling of stored grain on three farms showed that two of the eight bins sampled had R. dominica. The possible origins of the R. dominica (importation of infested grain, wind-borne migration from the United States, or an established Canadian population) are discussed.

Prostate adenocarcinoma is the most common malignant tumor of men in the United States and is the third leading cause of death in men. Despite attempts at early detection, there will be 244,000 new cases and 44,000 deaths from the disease in the United States in 1995. Therapeutic progress against this disease is hindered by an incomplete understanding of prostate epithelial cell biology, the availability of human tissues for in vitro experimentation, slow dissemination of information between prostate cancer research teams and the increasing pressure to “ stretch” research dollars at the same time staff reductions are occurring.To meet these challenges, we have used the correlative microscopy (CM) and client/server (C/S) computing to increase productivity while decreasing costs. Critical elements of our program are as follows:1) Establishing the Western Pennsylvania Genitourinary (GU) Tissue Bank which includes >100 prostates from patients with prostate adenocarcinoma as well as >20 normal prostates from transplant organ donors.

Quantitative Image

In recent years it became apparent that we needed to improve productivity and efficiency in the Microscopy Laboratories in GE Plastics. It was realized that digital image acquisition, archiving, processing, analysis, and transmission over a network would be the best way to achieve this goal. Also, the capabilities of quantitative image analysis, image transmission etc. available with this approach would help us to increase our efficiency. Although the advantages of digital image acquisition, processing, archiving, etc. have been described and are being practiced in many SEM, laboratories, they have not been generally applied in microscopy laboratories (TEM, Optical, SEM and others) and impact on increased productivity has not been yet exploited as well.In order to attain our objective we have acquired a SEMICAPS imaging workstation for each of the GE Plastic sites in the United States. We have integrated the workstation with the microscopes and their peripherals as shown in Figure 1.

Communities Of Interest

Every ten years, the United States “constructs” itself politically. On a decennial basis, U.S. Congressional districts are quite literally drawn, physically constructing political representation in the House of Representatives on the basis of where one lives. Why does the United States do it this way? What justifies domicile as the sole criteria of constituency construction? These are the questions raised in this article. Contrary to many contemporary understandings of representation at the founding, I argue that there were no principled reasons for using domicile as the method of organizing for political representation. Even in 1787, the Congressional district was expected to be far too large to map onto existing communities of interest. Instead, territory should be understood as forming a habit of mind for the founders, even while it was necessary to achieve other democratic aims of representative government.
