PurposeFrom the cataloging librarians' point of view, this paper aims to present how technical services, especially the cataloging department, can play important roles in the improvement of user services.Design/methodology/approachThe paper examines the practices of the University of Oklahoma Libraries.FindingsThe paper identifies several aspects in which technical services can enhance the quality of user services, especially in the cataloging department. A library's online catalog becomes the first point of access to the library's information resources. Its quality can be improved and enriched in many ways to raise users’ satisfaction. Aside from the improvement in technical aspects, efforts should also be made to promote collaboration between technical and public services so as to ensure efficient processing of materials and to meet the needs of library users.Originality/valueThe value of the paper is in showing that the quality of an online catalog and the cooperation between public and technical services are two of the key factors in achieving high quality of user services.

There are many complaints from the users and decision-makers towards the electronic information services as well as the delay in these services in the electronic business application programs at the informatics institutes. This indicates the low levels in the quality of performance of business application programs. The study has aimed to define the quality standards for electronic business application programs, to measure the quality levels and the importance of each performance standard, knowing the dissatisfaction of the users about the technical services and applications provided by the application programs, to determine the factors, and the reasons that affect the performance and the lack of user satisfaction, and to identify technical services and applications that are provided by business application programs in informatics institutions.The descriptive approach and the analytical method were adopted in the study, and a set of measurements are used to find out the statistics such as the end central limit theory, and Z and T testes. This paper has adapted new model with seven main standards including sixteen sub-standards to measure the level of the application standard quality of electronic business application programs as well as their importance at work. The results showed that the level of interest was directed to six main criteria with a high degree of importance, such as the criterion of flexibility, reliability, accuracy, speed of response and the criterion of achieving goals, while the criterion of inclusivity has obtained an important level. As for the performance level corresponding to all the criteria, it was low to medium (1-3 of five degrees representing the level of performance for the quality of the systems), with the exception of the reliability and confidence standard of the information provided, which can be approximated to the high performance level, with malfunctions in the electronic work of the systems with attempts to fix the existing malfunction. Finally, a set of recommendations was developed.

Welcome to the inaugural issue of the e-only Library Resources and Technical Services (LRTS)! We are starting the year with a new publication model for LRTS. The content and quality of the journal will remain constant, as will the submission criteria and review process. The difference is that you will no longer receive a print copy of the journal, and it will instead be delivered directly to your e-mail. Transitioning to e-only provides new opportunities. It removes page limits required for print and will enable full color copy (perfect for viewing LRTS covers and illustrative matter that accompanies papers). It will also enable us to explore new publication models used by other e-only scholarly journals. I am confident things will proceed smoothly under the watch of Tim Clifford of ALA Production Services, LRTS’s production editor, and Christine McConnell of ALCTS, LRTS’s manager. Tim has handled other ALA journals’ transition to e-only, and Christine has addressed issues related to subscriptions and publicity. I rest assured it will be a seamless transition.

Definition Of

During the past investigations of immunoferritin localization of intracellular antigens in ultrathin frozen sections, we found that the degree of negative staining required to delineate u1trastructural details was often too dense for the recognition of ferritin particles. The quality of positive staining of ultrathin frozen sections, on the other hand, has generally been far inferior to that attainable in conventional plastic embedded sections, particularly in the definition of membranes. As we discussed before, a main cause of this difficulty seemed to be the vulnerability of frozen sections to the damaging effects of air-water surface tension at the time of drying of the sections.Indeed, we found that the quality of positive staining is greatly improved when positively stained frozen sections are protected against the effects of surface tension by embedding them in thin layers of mechanically stable materials at the time of drying (unpublished).

Exposure Process

Most production electron beam lithography systems can pattern minimum features a few tenths of a micron across. Linewidth in these systems is usually limited by the quality of the exposing beam and by electron scattering in the resist and substrate. By using a smaller spot along with exposure techniques that minimize scattering and its effects, laboratory e-beam lithography systems can now make features hundredths of a micron wide on standard substrate material. This talk will outline sane of these high- resolution e-beam lithography techniques.We first consider parameters of the exposure process that limit resolution in organic resists. For concreteness suppose that we have a “positive” resist in which exposing electrons break bonds in the resist molecules thus increasing the exposed resist's solubility in a developer. Ihe attainable resolution is obviously limited by the overall width of the exposing beam, but the spatial distribution of the beam intensity, the beam “profile” , also contributes to the resolution. Depending on the local electron dose, more or less resist bonds are broken resulting in slower or faster dissolution in the developer.

Microscopic Investigations

Introduction In electron microscopic investigations of crystalline specimens the direct observation of the electron diffraction pattern gives additional information about the specimen. The quality of this information depends on the quality of the crystals or the crystal area contributing to the diffraction pattern. By selected area diffraction in a conventional electron microscope, specimen areas as small as 1 µ in diameter can be investigated. It is well known that crystal areas of that size which must be thin enough (in the order of 1000 Å) for electron microscopic investigations are normally somewhat distorted by bending, or they are not homogeneous. Furthermore, the crystal surface is not well defined over such a large area. These are facts which cause reduction of information in the diffraction pattern. The intensity of a diffraction spot, for example, depends on the crystal thickness. If the thickness is not uniform over the investigated area, one observes an averaged intensity, so that the intensity distribution in the diffraction pattern cannot be used for an analysis unless additional information is available.

Scanning Electron

In the observation of a thick specimen by means of a transmission electron microscope, the intensity of electrons passing through the objective lens aperture is greatly reduced. So that the image is almost invisible. In addition to this fact, it have been reported that a chromatic aberration causes the deterioration of the image contrast rather than that of the resolution. The scanning electron microscope is, however, capable of electrically amplifying the signal of the decreasing intensity, and also free from a chromatic aberration so that the deterioration of the image contrast due to the aberration can be prevented. The electrical improvement of the image quality can be carried out by using the fascionating features of the SEM, that is, the amplification of a weak in-put signal forming the image and the descriminating action of the heigh level signal of the background. This paper reports some of the experimental results about the thickness dependence of the observability and quality of the image in the case of the transmission SEM.

Radio Telescopes

With information processing devices such as radio telescopes, microscopes or hi-fi systems, the quality of the output often is limited by distortion or noise introduced at the input stage of the device. This analogy can be extended usefully to specimen preparation for the electron microscope; fixation, which initiates the processing sequence, is the single most important step and, unfortunately, is the least well understood. Although there is an abundance of fixation mixtures recommended in the light microscopy literature, osmium tetroxide and glutaraldehyde are favored for electron microscopy. These fixatives react vigorously with proteins at the molecular level. There is clear evidence for the cross-linking of proteins both by osmium tetroxide and glutaraldehyde and cross-linking may be a necessary if not sufficient condition to define fixatives as a class.
