Aviation English: An Introduction, Peter H. Ragan

Journal of Aviation/Aerospace Education & Research

Aviation is a specialized, technology-based area that covers a broad range of activities, from esoteric analyses of compressible fluids, to selling tickets, to getting a clearance for takeoff. Accordingly, the language behavior inherent to such activities is diverse, often requiring specialized uses of English that are collectively labeled here as Aviation English. Aviation English figures prominently in most fields of aviation/aerospace education and practice, in regulatory and administrative agencies concerned with national and international commerce, norms and standards, and in academic, industrial, and government research and development. A greater awareness of the nature of Aviation English and of relevant resources …

Correlated Confocal And Intermediate Voltage Electron Microscopy Imaging Of The Same Cells Using Sequential Fluorescence Labeling, Fixation, And Critical Point Dehydration, Lee D. Peachey, Harunori Ishikawa, Tohru Murakami

Scanning Microscopy

Confocal laser scanning microscopy (CLSM) and intermediate voltage transmission electron microscopy (IVEM) each has its own particular advantages. CLSM can examine living cells, but is particularly useful when applied to cells that have been lightly fixed, permeabilized, and stained with fluorescent-labeled antibodies for localization of specific molecular species at the resolution of the light microscope while still in the hydrated state. IVEM provides much higher resolution images, but requires more drastic preparation procedures, including dehydration. This paper presents methods for combining these complementary approaches to examine exactly the same cells sequentially by CLSM and IVEM. Cells are grown in culture …

Immunocytochemistry By Electron Spectroscopic Imaging Using Well Defined Boronated Monovalent Antibody Fragments, M. M. Kessels, B. Qualmann, W. D. Sierralta

Scanning Microscopy

Contributing to the rapidly developing field of immunoelectron microscopy a new kind of markers has been created. The element boron, incorporated as very stable carborane clusters into different kinds of peptides, served as a marker detectable by electron spectroscopic imaging (ESI) - an electron microscopic technique with high-resolution potential.

Covalently linked immunoreagents conspicuous by the small size of both antigen recognizing part and marker moiety are accessible by using peptide concepts for label construction and their conjugation with Fab' fragments. Due to a specific labeling of the free thiol groups of the Fab' fragments, the antigen binding capacity was not …

A Social Exchange Explanation Of Participation In The U.S. Farm Program, John K. Thomas, Jack Thigpen

Journal of Rural Social Sciences

Passage of the 1990 Food, Agriculture, Conservation, and Trade Act resulted from the political influence of many environmental interest groups and, consequently, included many conservation provisions. As agricultural policy has increasingly reflected the environmental concerns of the public, farmers who participate in the Farm Program have adjusted their production practices to conserve land and water resources, minimize use of agrichemicals, and control animal wastes. Social exchange theory was used to examine personal and farm characteristics that could affect agroenvironmental attitudes, Farm Program participation, and conservation practices of Texas farmers (n = 1,063 farmers) in 199 1. One in four farmers …

Farm Families Moving To Town: An Analysis Of Farm Population Declines, Don E. Albrecht

Journal of Rural Social Sciences

Recent census data indicate that a sizable proportion of individuals and families operating farms in the United States are choosing to live in urban and rural communities rather than on the farmstead. This phenomena is occurring in all regions of the country. In this paper, hypotheses are developed and tested to help explain and understand this phenomena and the variations that exist from county to county. County level data from the 1978 and 1987 Census of Agriculture and the 1980 and 1990 Census of Population are analyzed. Results show that counties with larger proportions of farm families living in the …

In Situ Hybridization, In Situ Transcription, And In Situ Polymerase Chain Reaction, L. E. De Bault, J. Gu

Scanning Microscopy

In situ hybridization, in situ transcription, and in situ polymerase chain reaction (PCR) are techniques used to detect DNA and RNA sequences within a cell or tissue structure. These three in situ methodologies employ the principles of recombinant DNA to form double-stranded hybrids of DNA-DNA, DNA-RNA, or RNA-RNA. The essence of in situ hybridization (ISH) is the hybridization of a labeled probe to a complementary target sequence, whereas in situ transcription (IST) is the synthesis of complementary DNA incorporating a label directly on the target DNA or RNA within a cell or tissue. In the case of in situ PCR …

Changing Employment Patterns In Nonmetropolitan America: Implications For Family Structure, Don E. Albrecht, Stan L. Albrecht

Journal of Rural Social Sciences

During the past few decades, the industria/employment structure of rural America has changed dramatically. The major causes of these changes have been technological developments which have reduced the human labor needs in the natural resources industries of agriculture, forestry, fisheries, and mining. While employment in the natural resources industries has declined, the loss of these jobs has been offset by increased employment in the manufacturing and service industries. This paper explores the relationship between variations in the industrial structure of nonmetropolitan counties in the United States and several family structure variables. It was found that counties with larger proportions of …

Conflict In The Community: A Challenge For Land Grant Universities, Thomas W. Ilvento

Journal of Rural Social Sciences

This paper revisits the notion of conflict in the community and then discusses a relatively new strategy for dealing with community conflict that is gaining popularity: alternative dispute resolution (ADR), particularly mediation. While ADRs are not entirely new, there has been a renewed interest in them as viable strategies for community development and public policy education. Conflict in communities is ubiquitous and should demand greater attention by rural sociologists, particularly those involved in community development. Environmental mediation is a strategy through which rural sociologists can effectively assist a community in resolving conflict Furthermore, as rural sociologists study and practice environmental …

Preparation Of Samples For Polymerase Chain Reaction In Situ, Gerard J. Nuovo

Scanning Microscopy

The purpose of this paper is to describe the key variables in sample and reagent preparation needed for successful polymerase chain reaction (PCR) in situ. Tissue or cell preparations should be fixed in a cross linking fixative, such as 10% buffered formalin, preferably from 15 to 48 hours. Tissues should be embedded in paraffin; cell preparations can be fixed when near confluence, then physically removed and processed. When possible three samples (4 μM tissue sections or 1-5000 cells) should be placed on silane coated glass slides. Digestion in pepsin (2 mg/ml) for 30 min is adequate for DNA detection …

Microscopic Analysis Of Dna And Dna-Protein Assembly By Transmission Electron Microscopy, Scanning Tunneling Microscopy And Scanning Force Microscopy, T. Müller-Reichhert, H. Gross

Scanning Microscopy

To investigate DNA and DNA-protein assembly, nucleic acids were adsorbed to freshly cleaved mica in the presence of magnesium ions. The efficiency of DNA adhesion and the distribution of the molecules on the mica surface were checked by transmission electron microscopy. In addition, various kinds of DNA-protein interactions including DNA wrapping and DNA super-coiling were analyzed using electron microscopy. In parallel, this Mg²⁺/mica method can be applied (1) to analyze embedded DNA by scanning tunneling microscopy, (2) to visualize freeze-dried, metal coated DNA-protein complexes by tunneling microscopy, and (3) to image DNA or DNA-protein interaction in air or …

Aspects Of Cryofixation And Cryosectioning For The Observation Of Bulk Biological Samples In The Hydrated State By Cryoelectron Microscopy, K. Richter

Scanning Microscopy

Cryoelectron microscopy allows the observation of hydrated samples at high spatial resolution, and it would be of great interest in biology to apply this method to cells and tissues. However, because of technical problems, the cryo-observation of frozen hydrated ultrathin sections of bulk material has not become an established method. The major limitations are due to the difficulty of achieving the vitrification of such material, and the structural deformation caused by ultrathin sectioning: 1. The vitrification of cells in a physiological environment requires high-pressure freezing. However, new results suggest that the pressure may alter the ultrastructure of the sample. 2. …

Electro-Optical Imaging Of F-Actin And Endoplasmic Reticulum In Living And Fixed Plant Cells, Nina Stromgren Allen, Marty N. Bennett

Scanning Microscopy

Confocal and video micrographs of living and fixed alfalfa roots, onion epithelial and pear pollen cells illustrate the architecture of the cytoskeleton and endoplasmic reticulum in plant cells. Fixation of plant tissues to preserve cytoplasmic structure poses special problems. When possible, emphasis should be placed on the imaging of structures in stained living cells over time. The early events that occur when Nod factors or bacteria elicit nodule formation in alfalfa roots will illustrate several approaches to plant cell fixation, staining and imaging. The first observable events after Nod factor stimulation occur in root hairs and are changes in rates …
