Dunn, J. "Curation of palynological material: a case study on the British Petroleum micropalaeontological collection." Geological Curator 7, no. 10 (2003): 365–72. http://dx.doi.org/10.55468/gc425.
Full textAbstract:
A curation and conservation survey of palynological material in the former British Petroleum Microfossil Collection is presented. The history of processing, slide preparation and storage of slides and residues in this 'industrial' collection is documented. The current conservation state of the collection suggests that good preparation techniques are critical to the long-term stability of palynology slide collections. The long term retention of duplicate residues is essential, providing a safeguard against damage or decay to original slides.

Full textAbstract:
For many years slide libraries in higher education institutions in the UK grew steadily in size as they accommodated the needs of new and expanding art and design courses. Although some slide librarians acquired new slides by photographing works of art in museums and art galleries, and most bought slides of the traditional art history canon from commercial publishers and art galleries, the largest proportion of these ever growing slide collections was made up of slides produced by copy photography, using slide film to photograph images taken from books, journals and exhibition catalogues. Changes in UK copyright law in 1988 made this illegal and jeopardised the ability of lecturers to present the visual material they needed for their courses. Slide librarians were forced to consider ways of getting around the law. A licence scheme ultimately emerged as the answer, but one that has its detractors and critics.

The microfossil collection in the University of California Museum of Paleontology (UCMP) in Berkeley is among the world’s largest. Its current holdings exceed 200,000 slides, 15,000 bulk samples, and two million washed residues. The UCMP database currently includes 10,191 type specimens of which 2,398 are primary types representing 10 microfossil groups. Although Cretaceous and Tertiary foraminifera from California and the south-central United States dominate the collection, it components are from all continents and oceans, range in age from Precambrian to Recent, and include specimens representing all 11 of the primary microfossil groups: foraminifera, ostracodes, calcareous nannoplankton, radiolarians, diatoms, silicoflagellates, conodonts, acritarchs, chitinozoans, dinocysts, and sporopollen. Also represented are chrysomonads, prasinophycean and coralline algae, ebriidians, and microplankton incertae sedis. The collection is dominated by the largest slide collection of fossil foraminifera from the West Coast of North America. Notable acquisitions in the past 25 years are the Loeblich and Tappan (UCLA) and Stanford University (LSJU) collections, and those donated by the regional divisions of Arco and Texaco. Adoption of these and other “orphaned†collections by the UCMP ensures their preservation and convenient accessibility for future study. The UCMPcollection spans the history of micropaleontology on theWest Coast of the United States, which began at the end of the 19th Century with studies by non-local paleontologists. In early 1920s, when the oil industry realized the value of microfossils in subsurface correlation, micropaleontology blossomed in California (as well as Texas) as a career-worthy discipline and slide collections soon sprouted out of the necessity to archive data and to create taxonomic reference sets. The core of the UCMP collection comprises its native component and the adopted UCLA and LSJU collections, and accounts for the more than 50,000 slides, including more than 10,000 primary and secondary types. Approximately 40,000 of those slides, including all of the types, have been entered into the UCMP digital database, which is publically accessible online. The other 10,000 are UCLA glass slides (mostly of Paleozoic palynomorphs) that are currently being processed. There is an additional backlog of another 79,000 slides representing 19 collections from individual micropaleontologists and more than two million slides and sample residues from the West Coast divisions of Arco and Texaco. Although some progress has been made on those, it will be many years before their curation and database entry approaches completion.

The Harvard mycologist Roland Thaxter collected and studied a wide variety of fungi. Although he described >1000 fungal species, he was unable to describe all the specimens he collected before his death in 1932. His collections and microscope slides remain an important resource for studying fungal diversity at the Farlow Herbarium at Harvard University. Thaxter described three species in the obligate mycoparasite genus Syncephalis: S. pycnosperma, S. tenuis, and S. wynneae. He retained slide mounts of several other species, including a new species from his collection that was not described. Here, we describe that new species as S. aethiopica based on morphological analysis of his preserved slides. We also discuss the morphology of S. reflexa, a species apparently only known from slides preserved at the Farlow Herbarium.

Visual forms of communication are dominant in the digital era. As the visual has increased in influence throughout contemporary culture, art & design slide collections, which would have traditionally helped users make sense of the visual world, have begun to rapidly disappear. How are students of art & design (and beyond) engaging with this visual proliferation now they can no longer rely on the support of the institutional slide collections and their expert staff?

Previous discussions of collections printed in Archaeological Reports have consisted of catalogues of antiquities. This contribution does not deal with antiquities per se, but with objects depicting antiquities – 46 glass plate photographic negatives dating to the nineteenth century. However, these objects are also culturally-produced artefacts. Most of them are large, approximately 20cm by 20cm, glass plates, though some are rectangular of both smaller and larger dimensions. In addition, there are seventeen duplicated images in a British standard 8.25cm by 8.25cm lantern slide format. These glass artefacts are remnants of a much larger collection of negatives and slides amassed by the Society for the Promotion of Hellenic Studies (hereafter Hellenic Society) in the late nineteenth to the first half of the twentieth century.

Full textAbstract:
How long does it take to digitize 11,000 film-based slides? Converting film to a raster graphic may take a relatively short period of time, but what is needed to prepare for the process, and then once images are digitized, what work is required to push data out for public access? And how much does the entire conversion process cost? A case study of a rapid-capture digitization project at the Smithsonian Institution will be reviewed. In early 2016, the Smithsonian Institution National Museum of Natural History (NMNH) Division of Fishes acquired 10,559 film-based slides from world-renown ichthyologist John (Jack) Randall. The first-generation slides contain images of color patterns of hundreds of fish species with locality information for each specimen written on the cardboard slide mount. When Jack began his photography in the 1960’s, his images were at the forefront of color photography for fishes. He also collected specimens in remote island archipelagos in the Pacific and Indian Oceans, thus many localities were, and continue to be, rare. The species represented on the slide are important to the scientific community, and the collection event data written on the slide mount makes the image and its metadata an invaluable package of information. Upon receipt of Jack’s significant donation, the Division of Fishes received multiple requests from ichthyologists for digital access to the slides. The Division of Fishes immediately implemented a plan to digitally capture data. With many rapid-capture projects at the Smithsonian, the objects and specimens are digitized, and then at some later point, any associated data is transcribed. The Division approached this project differently in that the Randall collection was relatively small, and Smithsonian staff, primarily interns, were available to transcribe data before image conversion. Post-production work included hiring two contractors to import images and associated metadata into NMNH’s collections management system. This presentation will review our processes before, during, and after data conversion. Workflows include transcribing handwritten data, staging and digitizing film, and importing data into the EMu client as well as using redundancies to ensure quality of data.

Full textAbstract:
Collections digitization relies increasingly upon computational and data management resources that occasionally exceed the capacity of natural history collections and their managers and curators. Digitization of many tens of thousands of micropaleontological specimen slides, as evidenced by the effort presented here by the Indiana University Paleontology Collection, has been a concerted effort in adherence to the recommended practices of multifaceted aspects of collections management for both physical and digital collections resources. This presentation highlights the contributions of distributed cyberinfrastructure from the National Science Foundation-supported Extreme Science and Engineering Discovery Environment (XSEDE) for web-hosting of collections management system resources and distributed processing of millions of digital images and metadata records of specimens from our collections. The Indiana University Center for Biological Research Collections is currently hosting its instance of the Specify collections management system (CMS) on a virtual server hosted on Jetstream, the cloud service for on-demand computational resources as provisioned by XSEDE. This web-service allows the CMS to be flexibly hosted on the cloud with additional services that can be provisioned on an as-needed basis for generating and integrating digitized collections objects in both web-friendly and digital preservation contexts. On-demand computing resources can be used for the manipulation of digital images for automated file I/O, scripted renaming of files for adherence to file naming conventions, derivative generation, and backup to our local tape archive for digital disaster preparedness and long-term storage. Here, we will present our strategies for facilitating reproducible workflows for general collections digitization of the IUPC nomenclatorial types and figured specimens in addition to the gigapixel resolution photographs of our large collection of microfossils using our GIGAmacro system (e.g., this slide of conodonts). We aim to demonstrate the flexibility and nimbleness of cloud computing resources for replicating this, and other, workflows to enhance the findability, accessibility, interoperability, and reproducibility of the data and metadata contained within our collections.

Full textAbstract:
The aim of paleontology is the understanding of the life history on Earth, its development and processes along the geologic time. Hence, it involves diversified fields, being the micropaleontology one of them, whose focus lies on taxonomy and appli-cations. The micropaleontology is, sometimes, poorly developed in an institution due to the scarcity of specialists. In order to fill this gap, a didactic collection was prepared to facilitate the divulgation of the micropaleontology in the university. Due to the necessity of increase in the knowledge on microfossils among graduate and undergraduate students, an extension project of mi-crofossils didactic collection was carried out at the Geology Department of the Universidade Federal de Pernambuco. For each fossil group (i.e. ostracods, foraminifers, calcareous nannofossils, charophytes, radiolarians, diatoms, conodonts, palyno-morphs, fish fragments, echinoid spines, sponge spicules and mollusks) micropaleontological slides were assembled. The origin of the material is varied, with specimens from several Brazilian sedimentary basins and even from other countries. The collections consist in numbered and identified slides, besides the material necessary for their manipulation, such as brushes and spare slides. In each fossil group, the specimens are organized according to the morphology, taxonomy and age. Each slide has instructions for classes inserted in a Guidebook of Micropaleontology thoroughly illustrated, with general characteristics of each fossil group and the respective methodology for sample preparation. The collection is intended to be used in practical classes, workshops and short-courses, with biological, petrographic and stereoscopic microscopes, for observation of the mor-phological structures, identification and solution of problems proposed in the guidebook. Besides the improvement in the pale-ontology teaching, these collections will also contribute to the qualification of the students as future professionals.

Full textAbstract:
Morphological studies of small invertebrates often involve the preparation of slides to observe minute body parts under a compound microscope. Preparation should facilitate observation, through traditional optical microscopy, of small surface structures on different planes, like pores, spines and setae. Various methods and techniques, using different mounting media that specialists have adopted to observe and preserve small crustaceans, have their advantages and disadvantages. Within the order Bathynellacea, specimens in the family Bathynellidae are particularly challenging due to their small size (0.5 to 2.25 mm body length) and very delicate exoskeleton, which tends to be completely digested when using common clearing mounting media, making future consultations impossible. Permanent slides are fundamental to preserve small specimens for scientific collections, because temporary slide preparations can easily result in the loss of body parts in the passage between slide and vial and vice versa. Dr Eugene Serban worked on Bathynellacea for more than 40 years, improving the preparation and preservation of delicate specimens using a stained glycerol-jelly and double cover slip mounting technique. His method is described here with a variation that speeds up the original procedure and was implemented in most recent years by one of the authors (A.I.C.). The technique provides excellent preservation and visualization of body parts on permanent slides, which do not need curation tasks and can last for many years.

This descriptive type of cross-sectional study was conducted to find out the views of undergraduate dental college teachers about the PowerPoint presentations as instructional media used by teachers in dental colleges of Bangladesh. The study period was from January 2018 to December 2018. The study was carried out among the teachers of all 4 phases of BDS course of 2 government and 2 non-government dental colleges of Bangladesh. Out of 4 dental colleges, 2 were within Dhaka and 2 were outside Dhaka. The sample size was 100 for teachers. Convenience sampling technique was adopted for data collection. Self-administered semi-structured questionnaires using five points Likert scale were used for collections of data from teachers. The study revealed that 72% teachers consider Eye appealing appearance for choosing PowerPoint slides and 58% teachers did not use master slide. For selection of font style, 67% teacher agreed they consider readability, 88% agreed they consider visibility from last bench of classroom to select font size but 61% teacher disagree that they consider background for selecting font color. The study recommended, during the preparation of a PowerPoint presentation by teachers some areas like using the master slide, background, the number of words and lines need attention.

Full textAbstract:
Microscope slide collections represent extremely valuable depositories of research material in a natural history, forensic, veterinary, and medical context. Unfortunately, most mounting media of these slides deteriorate over time, with the reason for this not yet understood at all. In this study, Raman spectroscopy, ultraviolet–visible (UV–Vis) spectroscopy, and different types of light microscopy were used to investigate the ageing behaviour of naturally aged slides from museum collections and the experimentally aged media of Canada balsam and PermountTM, representing a natural and a synthetic resin, respectively, with both being based on mixtures of various terpenes. Whereas Canada balsam clearly revealed chemical ageing processes, visible as increasing colouration, PermountTM showed physical deterioration recognisable by the increasing number of cracks, which even often impacted a mounted specimen. Noticeable changes to the chemical and physical properties of these mounting media take decades in the case of Canada balsam but just a few years in the case of PermountTM. Our results question whether or not Canada balsam should really be regarded as a mounting medium that lasts for centuries, if its increasing degree of polymerisation can lead to a mount which is no longer restorable.

Context.— Current technologies including digital slide scanners and handheld devices can revolutionize clinical practice and pathology graduate medical education (GME). The extent to which these technologies are used in pathology GME is unknown. Objectives.— To determine the types of technologies used, usage amount, and how they are integrated into pathology residency/fellowship programs nationwide. Design.— A 40-question online survey for residents/fellows was developed and administered via the Research Electronic Data Capture System after institutional review board approval. Results.— Fifty-two program directors (37%) gave permission for participation. One-hundred seventy-one responses were received (18% response rate). Most respondents have access to personal technology (laptop = 78% [134 of 171]), smartphone = 81% [139 of 171], tablet = 49% [84 of 171]), and Web-based digital slide collections (82%, 141 of 171). Few residents are provided electronic devices by their programs (laptop = 22% [38 of 171], smartphone = 0.5% [1 of 171], and tablet = 12% [21 of 171]). Fifty-nine percent have access to digital slide scanners, 33% have access to a program-created database of digitized slides, and 52% use telepathology. Fifteen percent have access to asynchronous learning. Of those with access to video-recorded conferences, 89% review them. Program size was significantly positively correlated with resident access to program-provided laptops (P = .02) and tablets (P < .001), digital slide scanners (P = .01), and telepathology (P = .001). Of all devices, program-provided laptops are used most for professional work (60.5% use this device for more than 5 hours per day). Conclusions.— Most residents report access to multiple types of innovative technology, but incorporation of these tools within pathology training programs is highly variable. Opportunities for incorporating innovative technologies exist and could be further explored.

Full textAbstract:
Zoological collections house a huge range of biological diversity preserved in a wide variety of ways ranging from microscope mounts to whole animals preserved in fluids. The result is that these collections consist of a wide range of differing materials which can make the long term care and conservation of such collections a considerable challenge. This workshop is designed for museum professionals with the aim of giving an introductory overview on museum conservation approaches towards the care of zoological collections. This will be achieved through identifying the key risks and looking at the application of both remedial and preventative conservation methodologies to their care. The format of the workshop will be lectures on specific topics with group discussions, along with (where feasible) activities in small groups and practical examinations of specimens. Topics covered will include: Introduction to the concepts of ‘museum conservation’ and its application within the Natural Sciences. The types of material found in zoological collections – an overview of the core collection types, the chemistry of preservation and the potential long term challenges these present. An overview of the key agents of deterioration. Environmental effects and how to recognise them. Awareness of hazardous materials and core H&S issues encountered with the care and handling of zoological collections. Assessing collections and deciding conservation priorities. Fur, feathers and bones - practical conservation approaches to cleaning, consolidation and repair. Fluid collections - practical conservation approaches to handling, identifying fluids and carrying out remedial activities. Other key collection areas – e.g. conservation of entomology and other dried invertebrate collections; microscope slide collections. Consideration of the care and conservation of specialist collections e.g. historic models such as Blaschka glass models. Discussion and feedback from attendees will be a core part of the day.

The genus Leucapamea was erected by Sugi (1982). The most recent revision of the genus was provided by Zilli et al. (2009), and include descriptions of five new species. Leucapamea species are diagnosed by the whitish ground colour of forewings and the very long, sword-like superior saccular process. Leucapamea is distinguished from the related genus Lateroligia Zilli, Fibiger & Ronkay, 2005 by the triangular cucullus having only a slight ventral extremity and the presence of the strong cornutus in the vesica. Thirteen species of Leucapamea have been described (Zilli et al. 2009), four of which are endemic to Taiwan, two to Japan, and the other species distributed from the northern Pacific to Southern China and Vietnam. Following research in Sichuan during the last years, an additional species is described and diagnosed here.Abbreviations for personal and institutional collections used herein are as follows: AFM = Alessandro Floriani (Milan, Italy); ASV = Aidas Saldaitis (Vilnius, Lithuania); HNHM = Hungarian Natural History Museum (Budapest, Hungary); PGM = collection of Péter Gyulai (Miskolc, Hungary); GYP = genitalia slide of P.

Visual resource professionals (VRPs) for years provided high-quality, subject specific, copyright cleared images for teaching and research in higher education in the UK by maintaining slide collections. As the rapid march of technology left the 35mm slide in its wake, VRPs found themselves unable to provide the digital alternative because their hands were bound by outdated copyright law. They began sounding the alarm over ten years ago and have been calling for a resolution ever since, but to no avail. Why have their calls not been heeded? How have VRPs responded to the resulting dilemma, and where does it leave the copyright status of the images used in everyday teaching in the UK?

Full textAbstract:
Abstract Physician shortages are acute in developing countries, where disease burden is the greatest and resources for health care are very limited. A lack of pathologists in these countries has lead to delays in diagnosis and misdiagnoses that adversely affect patient care and survival. The introduction of telepathology into countries with limited resources for health care is but one of multiple approaches that can be used to alleviate the problem. Telepathology is the electronic transmission of digital images that can be used for education and diagnostic consultation. A basic system consists of a microscope with a mounted digital camera linked to a computer. The ability to produce histologic slides, to repair and maintain equipment, and to provide training are also needed for the successful use of this technology. iPath is a Web-based, open platform, software application which was developed at the University of Basel, Switzerland, for telepathology and which brings together pathologists from around the world to provide telepathology support for diagnostic consultation and provides education to centers with limited resources. The use of virtual-slide technology to provide a digital image of an entire glass slide is another technology for diagnostic consultation and pathology education. This technology requires more costly resources to support it, which may limit its utility in many areas. Telepathology can generate collections of digital images and virtual slides needed for training indigenous pathologists in their countries to become self-sufficient. Thus, the long-term goal of this technology is to improve patient care and survival.

A few years ago I attended a lecture by a well-known digital libraries researcher who, when discussing the issue of digital preservation, clicked forward to a PowerPoint slide that included Pablo Picasso’s iconic ink illustration of Don Quixote, the placement of which seemed a little too conveniently symbolic to be accidental. Regardless of the presenter’s intent, it is clear that the quest for sound and simple processes to support the management and preservation of electronic records—now often referred to as “born-digital” records—has remained a Quixotic one for many manuscripts curators and archivists, even more than two decades into . . .

Full textAbstract:
AbstractAn account is given of the development of aqueous gum-chloral mounting media used for mounting small arthropods on microscope slides. Berlese’s fluid is shown to have never been used by Berlese and other formulae are shown to have been randomly attributed to various authors, often incorrectly. Erroneous formulae and modifications to formulae have been followed by subsequent workers without reference to their origin. Details of the five formulae currently recommended in the literature are given and serious problems are shown to have been encountered with all of them by many workers. In many collections throughout the world gum-chloral slides are steadily deteriorating and specimens becoming irretrievably lost. Those workers advocating the use of gum-chloral aqueous media continue to propose alternative techniques in an attempt to overcome the problems they admit still occur. It is recommended that these media be used only for temporary mounts and never for specimens of taxonomic significance.

Full textAbstract:
Two new species of Bibloplectus Reitter, 1881 are described from the Orlando Park Collection of Pselaphinae at the FMNH (Field Museum of Natural History, Chicago, IL, USA): Bibloplectus silvestris Owens and Carlton, new species (type locality, Urbana, IL, USA) and Bibloplectus wingi Owens and Carlton, new species (type locality, Shades State Park, IN, USA). Types of these new species were part of a series of specimens bearing unpublished Park manuscript names in both the pinned and slide collection at the FMNH. They bring the total number of species in the genus in eastern North America to twenty-three. Resolving these manuscript names adds to previous efforts to uncover elements of the hidden diversity of North American Bibloplectus from museum collections (Owens and Carlton 2016, Owens and Carlton 2017) and highlights the importance of close examination of the Orlando Park pselaphine collection as a valuable historic and taxonomic resource.

Full textAbstract:
35mm still image formats are some of the most abundant photographic film types in cultural heritage collections. However, their special handling needs coupled with high resolution digital capture requirements have traditionally posed logistical constraints with regard to the formats' digitization at scale. Through the use of a programmable X-Y table camera capture system, both slide and strip 35mm photographic film can be digitized in an automated fashion following Federal Agencies Digitization Guidelines (FADGI).

Full textAbstract:
Dogs produce fewer sperm than other species. Furthermore, for French Bulldogs, anatomical peculiarities, low libido, and increased sensitivity to stress could cause further reductions in sperm count. The objective was to compare effects of semen collection at 24- versus 48-h intervals on semen quality of French Bulldogs. Five purebred French Bulldogs, 19 to 48 months old, were subjected to 5 semen collections (24 h apart). After a 30-day rest, collections were repeated, but the interval between collections was 48 h. Semen was collected (all 3 fractions) by digital manipulation without female stimuli. Volume was measured in a 20-mL syringe. Sperm concentration was determined with a Neubauer counting chamber. Motility and vigor were evaluated with a coverslipped drop of semen on a slide (preheated to 37°C). Motility was expressed as a percentage of motile sperm, and vigor was classified on a scale of 1 to 5. Morphology was evaluated by the panoptic method; 100 cells were counted and results expressed as the percentage of normal or defective cells. Effects of collection interval were analysed using PROC MIXED of SAS (animal as subject and collection as a repeated measure), with collections 2 to 5 compared with collection 1 (using the DIFF option). For collection every 24 h, the third, fourth, and fifth sperm collections were lower than the first collection for volume (10.4 ± 1.1, 8.3 ± 1.1, 5.6 ± 1.1, 3.5 ± 1.1, 2.4 ± 1.1 mL), concentration (437 ± 24, 448 ± 24, 370 ± 24, 322 ± 27, 258 ± 31 ×106 sperm mL–1), vigor (4.6 ± 0.2, 4.2 ± 0.2, 3.6 ± 0.2, 3.7 ± 0.2, 3 ± 0.2), and morphologically normal sperm (82 ± 2.2, 83 ± 2.2, 72 ± 2.2, 68 ± 2.5, 66 ± 2.9%). However, when the interval was increased to 48 h, only the fourth and fifth collections were lower (P < 0.05) than the first for volume (11.8 ± 1.1, 10.2 ± 1.1, 8.8 ± 1.1, 6.6 ± 1.1, 2.5 ± 1.1 mL), concentration (447 ± 24, 410 ± 24, 407 ± 24, 322 ± 24, 241 ± 31 ×106 sperm mL–1), vigor (5 ± 0.2, 4.8 ± 0.2, 4.4 ± 0.2, 4.2 ± 0.2, 4 ± 0.2), and sperm with normal morphology (92 ± 2.2, 90 ± 2.2, 87 ± 2.2, 80 ± 2.2, 81 ± 2.9%). Motility decreased (P < 0.05) following the fourth collection at 24-h intervals and decreased (P < 0.05) after the third collection at 48-h intervals. With a 24-h interval, 4 dogs had <60% motility lower at the fifth collection, whereas only 2 dogs had motility <60% on the fifth collection at 48-h intervals. In conclusion, semen collected at 48-h intervals was of better quality than semen collected at 24-h intervals.

Full textAbstract:
Whole slide imaging (WSI) refers to the process of creating a high-resolution digital image of a whole slide. Since digital images are typically produced by stitching image sequences acquired from different fields of view, the visual quality of the images can be degraded owing to shading distortion, which produces black plaid patterns on the images. A shading correction method for brightfield WSI is presented, which is simple but robust not only against typical image artifacts caused by specks of dust and bubbles, but also against fixed-pattern noise, or spatial variations in pixel values under uniform illumination. The proposed method comprises primarily of two steps. The first step constructs candidates of a shading distortion model from a stack of input image sequences. The second step selects the optimal model from the candidates. The proposed method was compared experimentally with two previous state-of-the-art methods, regularized energy minimization (CIDRE) and background and shading correction (BaSiC) and showed better correction scores, as smooth operations and constraints were not imposed when estimating the shading distortion. The correction scores, averaged over 40 image collections, were as follows: proposed method, 0.39 ± 0.099; CIDRE method, 0.67 ± 0.047; BaSiC method, 0.55 ± 0.038. Based on the quantitative evaluations, we can confirm that the proposed method can correct not only shading distortion, but also fixed-pattern noise, compared with the two previous state-of-the-art methods.

Full textAbstract:
A wide range of aspects concerning microscope slides, their preparation, long-time storage, curatorial measures in collections, deterioration, restoration, and study is summarized based on our own data and by analyzing more than 600 references from the 19th century until 2016, 15 patents, and about 100 Materials Safety Data Sheets. Information from systematic zoology, conservation sciences, chemistry, forensic sciences, pathology, paleopathology, applied sciences like food industry, and most recent advances in digital imaging are put together in order to obtain a better understanding of which and possibly why mounting media and coverslip seals deteriorate, how slides can be salvaged, which studies may be necessary to identify a range of ideal mounting media, and how microscope studies can benefit from improvements in developmental biology and related fields. We also elaborate on confusing usage of concepts like that of maceration and of clearing. The chemical ingredients of a range of mounting media and coverslip seals are identified as much as possible from published data, but this information suffers in so far as the composition of a medium is often proprietary of the manufacturer and may vary over time. Advantages, disadvantages, and signs of deterioration are documented extensively for these media both from references and from our own observations. It turns out that many media degrade within a few years, or decades at the latest, except Canada balsam with a documented life-time of 150 years, Euparal with a documented life-time of 50 years, and glycerol-paraffin mounts sealed with Glyceel, which represents almost the only non-deteriorating and easily reversible mount. Deterioration reveals itself as a yellowing in natural resins and as cracking, crystallization, shrinkage on drying or possibly on loss of a plasticizer, detachment of the coverslip, segregation of the ingredients in synthetic polymers, as well as continued maceration of a specimen to a degree that the specimen virtually disappears. Confusingly, decay does not always appear equally within a collection of slides mounted at the same time in the same medium. The reasons for the deteriorative processes have been discussed but are controversial especially for gum-chloral media. Comparing data from conservation sciences, chemical handbooks, and documented ingredients, we discuss here how far chemical and physical deterioration probably are inherent to many media and are caused by the chemical and physical properties of their components and by chemicals dragged along from previous preparation steps like fixation, chemical maceration, and physical clearing. Some recipes even contain a macerating agent, which proceeds with its destructive work. We provide permeability data for oxygen and water vapor of several polymers contained in mounting media and coverslip seals. Calculation of the penetration rate of moisture in one example reveals that water molecules reach a specimen within a few days up to about a month; this lays to rest extensive discussions about the permanent protection of a mounted specimen by a mounting medium and a coverslip seal. Based on the ever growing evidence of the unsuitable composition and application of many, and possibly almost all, mounting media, we strongly encourage changing the perspective on microscope slides from immediate usability and convenience of preparation towards durability and reversibility, concepts taken from conservation sciences. Such a change has already been suggested by Upton (1993) more than 20 years ago for gum-chloral media, but these media are still encouraged nowadays by scientists. Without a new perspective, taxonomic biology will certainly lose a large amount of its specimen basis for its research within the next few decades. Modern non-invasive techniques like Raman spectroscopy may help to identify mounting media and coverslip seals on a given slide as well as to understand ageing of the media. An outlook is given on potential future studies. In order to improve the situation of existing collections of microscope slides, we transfer concepts as per the Smithsonian Collections Standards and Profiling System, developed for insect collections more than 25 years ago, to collections of slides. We describe historical and current properties and usage of glass slides, coverslips, labels, and adhesives under conservational aspects. In addition, we summarize and argue from published and our own experimental information about restorative procedures, including re-hydration of dried-up specimens previously mounted in a fluid medium. Alternatives to microscope slides are considered. We also extract practical suggestions from the literature concerning microscope equipment, cleaning of optical surfaces, health risks of immersion oil, and recent improvements of temporary observation media especially in connection with new developments in digital software.

Full textAbstract:
The development of increasingly sophisticated methods to acquire high-resolution images has led to the generation of large collections of biomedical imaging data, including images of tissues and organs. Many of the current machine learning methods that aim to extract biological knowledge from histopathological images require several data preprocessing stages, creating an overhead before the proper analysis. Here we present PyHIST (https://github.com/manuel-munoz-aguirre/PyHIST), an easy-to-use, open source whole slide histological image tissue segmentation and preprocessing command-line tool aimed at tile generation for machine learning applications. From a given input image, the PyHIST pipeline i) optionally rescales the image to a different resolution, ii) produces a mask for the input image which separates the background from the tissue, and iii) generates individual image tiles with tissue content.

Full textAbstract:
In Spring 1999 the Art Libraries Society/The Netherlands (OKBN) plans to organize a conference on ‘Book & Image: Visual Resources and Art Libraries’, to discuss various aspects of the whereabouts, accessibility and use of visual resources in art libraries and other collections of art historical documentation. By doing this we hope to increase awareness amongst art librarians and visual resource librarians of the necessity of communicating questions and sharing their experiences. In particular we need to find new ways of co-operating in order to meet the challenges posed by new technological developments and future users. A small working group of ARLIS-NL members, joined by some colleagues from slide libraries and visual archives, already meets bi-monthly for brainstorming sessions aimed at preparing an attractive and challenging program for this event.

Full textAbstract:
Purpose: Preparing bone marrow smears using non-anticoagulated bone marrow aspirate is a traditional practice but many laboratories now use anticoagulated aspirate samples in K-EDTA. There are no published studies comparing the effectiveness of these two methods. This report compares the readability of slides, prepared using non-anticoagulated and anticoagulated methods, from three laboratories in Hamilton Ontario. Methods: A blinded set of 129 aspirate slides prepared using anticoagulated and non-anticoagulated methodologies (using K-EDTA) was reviewed by three reviewers. Slides were classified as unreadable if two of the three observers rejected them based on a standardized survey. Results: The proportion of slides classed as unreadable varied widely (5.0% to 46.9%) depending on collection and slide preparation methods. Degree of coagulation did not affect readability. Conclusion: A measurable advantage to using non-anticoagulated bone marrow was not demonstrated. Immediate anticoagulation of bone marrow samples, with laboratory personnel at the bedside to assess sample quality, followed by slide preparation in the laboratory provided the best results.

Full textAbstract:
Australian collections of the Colletotrichum gloeosporioides group and closely related species were studied to assess the suitability of existing taxonomic criteria and to examine the possibility of using alternative characters in the delimitation of taxa within the group. Conidia produced on free hyphae in slide cultures were consistently more variable than those produced in conidiomata in pure culture. Because of this, only dimensions of conidia from conidiomata should be used in taxonomic work. Appressorium morphology but not size was a useful addition to existing taxonomic criteria, with some isolates producing only unlobed or slightly lobed appressoria and others deeply lobed appressoria. On the basis of dimensions of conidia produced in conidiomata and appressorium morphology three biological groups emerge: isolates with mean conidial widths between 3.0 and 4.2 µm, with either unlobed or slightly lobed appressoria; isolates with mean conidial widths between 4.5 and 5.5 µm, with unlobed or slightly lobed appressoria; and isolates with conidial widths between 4.5 and 5.5 µm, with obviously lobed appressoria. Hyphal conidiogenesis appears to be useful in delimiting taxa only in C. crassipes where hyphal conidia were borne on branched conidiophores that were relatively short and stout. All other collections examined produced hyphal conidia on long, unbranched conidiophores, indistinguishable from normal hyphae.

Full textAbstract:
In 1977, R. E. Crabill, Jr., erected Ectonocryptops for a new Mexican centipede from Colima that he named, E. kraepelini. He placed it in the Cryptopidae, but with 23 pairs of legs and pedal segments, it properly belongs in the Scolopocryptopidae, subfamily Ectonocryptopinae, according to today's taxonomy (Shelley & Mercurio 2005). Crabill did not provide illustrations, and the holotype and only specimen, supposedly at the American Museum of Natural History, New York, USA (AMNH), was subsequently lost. Consequently, the identity of this centipede was uncertain until we (Shelley & Mercurio 2005) proposed Ectonocryptoides quadrimeropus, n. gen., n. sp., for an anatomically similar form from neighboring Jalisco. Discovery of the latter allowed us to interpret characterizations in Crabill's verbal account of Ectonocryptops kraepelini, and separate generic status seemed warranted because of different numbers of podomeres on the caudal legs, four in Ectonocryptoides quadrimeropus and five in Ectonocryptops kraepelini (Crabill 1977). Repeated and extensive searches in the type and general collections at the AMNH failed to reveal the missing holotype as did ones at the National Museum of Natural History, Smithsonian Institution, Washington, DC, where Crabill was a curator when he described Ectonocryptops kraepelini. The holotype was discovered in the AMNH by the second author in 2005; the cephalic plate & antennae, coxosternum & segments 1–7, and segments 19–23 plus the caudal legs had been dissected, cleared, and mounted on a slide, whereas segments 8–18 were in a vial of alcohol. The slide mount was in extremely poor condition with darkened and cracked medium that was filled with air bubbles and meniscuses such that critical parts could not be clearly viewed. We removed the mounted parts from the slide, placed them in alcohol with the rest of the specimen, and redescribe Ectonocryptops kraepelini and provide, for the first time, illustrations of anatomical features. We also provide new accounts of the subfamily, Ectonocryptoides, and Ectonocryptoides quadrimeropus, so that all subfamilial components are treated in a single publication. Asterisks (*) in the account of Ectonocryptops kraepelini denote items taken from Crabill's (1977) description that we could not confirm.

Full textAbstract:
In the past and still today, teaching aids have played an important role in providing future teachers with quality education. Their use in schools was affected by different historical contexts of education, school regulations as well as the development of industry, science, and didactics. After the Second World War, the use of a variety of media, such as tape recorder, radio, episcope, and slide projector, spread with electrification. As can be gathered from its well-equipped cabinet, the Imperial-Royal College of Education for Men in Koper (1875–1909) devoted much attention to teaching aids, especially in physics instruction. On its establishment after the Second World War, the college of education for southern Littoral, first opened in Portorož, also provided teaching aids, collections of teaching aids, and educational technology. In the absence of continued tradition, the college faced a lack of teaching aids. At the end of the 1950s, increasingly less teaching aids were bought as colleges of education converted into high schools of education sciences.

Full textAbstract:
Molecular motors embedded within collections of actin and microtubule filaments underlie the dynamics of cytoskeletal assemblies. Understanding the physics of such motor-filament materials is critical to developing a physical model of the cytoskeleton and designing biomimetic active materials. Here, we demonstrate through experiments and simulations that the rigidity and connectivity of filaments in active biopolymer networks regulates the anisotropy and the length scale of the underlying deformations, yielding materials with variable contractility. We find that semiflexible filaments can be compressed and bent by motor stresses, yielding materials that undergo predominantly biaxial deformations. By contrast, rigid filament bundles slide without bending under motor stress, yielding materials that undergo predominantly uniaxial deformations. Networks dominated by biaxial deformations are robustly contractile over a wide range of connectivities, while networks dominated by uniaxial deformations can be tuned from extensile to contractile through cross-linking. These results identify physical parameters that control the forces generated within motor-filament arrays and provide insight into the self-organization and mechanics of cytoskeletal assemblies.

Full textAbstract:
ErylusGray (Porifera: Geodiidae) has been recorded in Australian waters from two antiquated reports (E. lendenfeldi Sollas, 1888 and E. proximus Dendy, 1916). These two species are redescribed. From more recent collections from the Great Barrier Reef, Coral Sea, southern Queensland and Western Australia four new species (E. amissus, E. circus, E. citrus and E. fromonta, spp. nov.) were discovered and are described. One other, presently unrecognisable, species from an antiquated museum slide preparation is also described. A tabular review of species worldwide is also provided. Erylus has been an important source of novel bioactive compounds, including those with antitumor and antifungal properties and that are helpful in combating autoimmune diseases (including HIV). This discovery of four new species, increasing the diversity of the genus by 66% in Australian waters, has important implications pertaining to the existence of new compounds, or analogues of existing compounds unique to Erylus, as potential therapeutic marine natural products.

The method may be recommended for cases when the express identification is needed: in quarantine and plant protection services, and as an auxiliary method in molecular and applied investigations, to prove reliability of the species identification after years and future taxonomic changes. The method includes killing, fixation, processing in glycerin, and preparation of slides using an Eppendorf tube at high temperature (60-95 °C).

Polyclonal antisera to detect and determine two related pathovars, Pseudomonas syringae pv. pisi and Pseudomonas syringae pv. syringae, were prepared Untreated bacterial cells, or fixed by formaldehyde or glutaraldehyde were used as antigens. After cross-absorption with heterologous antigens, antisera revealed a high level of specificity in slide agglutination, Ouchterlony gel double-diffusion and in DAS-ELISA and PTA-ELISA. Each of 14 P s. pisi prepared polyclonal antisera could detect and deter mine all strains of P s. pisi, regardless of race. PTA-ELISA was the most appropriate serological test to distinguish Pseudomonas syringae pathovars on peas. Most of the P s. pisi strains from foreign collections were in serological tests confirmed asP. s. pisi, while most of the Czech strains suspected as P s. pisi were determined as P s. syringae strains. The principal biochemical reaction, i.e., use of DL-homoserine as a carbon source to grow P s. pisi but not P s. syringae , was proved not to be sufficiently reliable to distinguish both pathovars.

Full textAbstract:
This research involved the evaluation of a multimodal asynchronous communications tool to support collaborative analysis of post-operations in the National Airspace System (NAS). Collaborating authors have been shown to provide different feedback with asynchronous speech based communications compared to text. Voice synchronized with pointing in asynchronous annotation systems has been found to be more efficient in scheduling tasks, than voice-only, or text only communication. This research investigated how synchronized voice and pointing annotation over asynchronously shared slide shows composed of post operations graphical and tabular data differs in its effect compared to text based annotation, as collections of flights ranked low by standard performance metrics are discussed by FAA (Federal Aviation Administration) and airline representatives. The results showed the combined problem solving and message creation time was shorter when working in the voice and pointing mode than the text based mode, without having an effect on the number and type of ideas generated for improving performance. In both modes the system was also considered useful and usable to both dispatchers and traffic managers.

Data Sources.— Literature review from PubMed, urologic pathology textbooks, and the 4th edition of the World Health Organization Classification of Tumours of the Urinary System and Male Genital Organs. All photomicrographs were taken from cases seen at Weill Cornell Medicine or from the authors' personal slide collections. Conclusions.— The clinical importance and histologic criteria are well established for the known precursor lesions of the most common malignancies throughout the genitourinary tract, but further investigation is warranted at the molecular level to better understand the pathogenesis of these lesions. Such investigation may lead to better risk stratification of patients and potentially novel treatments.

Developments in digital imaging and fluorescent microscopy provide a new method and opportunities for quantification of protein expression in human tissue. Archived collections of paraffin-embedded tumors can be used to study the relationship between quantitative differences in protein expression in tumors and patient outcome. In this report we describe the use of a DeltaVision Restoration deconvolution microscope, combined with fluorescent immunohistochemistry, to obtain reproducible and quantitative estimates of protein expression in a formalin-fixed paraffin-embedded tissue. As proof of principle, we used antibodies to the estrogen and progesterone receptors in a hormone receptor–positive breast cancer specimen. We provide guidelines for control of day-to-day variability in camera and microscope performance to ensure that image acquisition leads to reproducible quantitative estimates of protein expression. We show that background autofluorescence related to formalin fixation can be controlled and that for proteins that are expressed in nearly every cell, multiplexing two primary antibodies on the same slide does not significantly affect the results obtained. We demonstrate that for proteins whose expression varies markedly from cell to cell, data reproducibility, as assessed by imaging successive tissue sections, is more difficult to determine.

Full textAbstract:
Citrus groves in Florida were sampled during February and March 1991 to determine the occurrence, frequency and distribution of thrips including Thrips palmi Karny in open flowers of citrus. Frankliniella bispinosa (Morgan) was the dominant species accounting for 65% of identified specimens from St. Lucie, Palm Beach, Hendry, Lee and DeSoto counties. Frankliniella kelliae Sakimura was the second most abundant species comprising 34% of 2,067 slide-mounted specimens subsampled from collections. Frankliniella kelliae was found for the first time in St. Lucie and Indian River counties and this species was the most abundant thrips collected from citrus flowers in Indian River and Dade counties. Five species of thrips including Frankliniella occidentalis (Pergande), T. orientalis (Bagnall), T. palmi and Adraneothrips pallidus (Watson) were collected for the first time in February and March 1991 on citrus flowers along with F. insularis (Franklin) reported previously. A single adult female, T. palmi, was collected from a ‘Tahiti’ lime flower sample in Dade County. The predaceous thrips, Aleurodothrips fasciapennis (Franklin), was collected for the first time from flowers in a mixed block of citrus varieties in Dade County. A key to the species of adult female terebrantian thrips found on citrus flowers and floral buds in Florida is provided.

The practice of using photography, whether in digital, slide, or print form, is a fundamental method of documenting and preserving finds and information in archaeology and most other museum-related disciplines. Images play an important role in the communication and preservation of information and can be regarded as archival collections in their own right. However, in many situations it is difficult to store and search efficiently through this vital resource. With the advent of desktop databases and interconnectivity, images can be readily organized into a searchable database. This approach becomes especially useful when dealing with the huge numbers of photographs accumulated through large projects. The EPIC database is a good example of the solution to this problem. EPIC was created to deal with images generated through one research centre of a large archaeological project (SCAPE: Study of Cultural Adaptations in the Canadian Prairie Ecozone). Built around off-the-shelf software, EPIC allows users to view a small thumbnail of an image with associated information, and has been designed to facilitate multiple search pathways. It also has the ability to link to related Museum databases. EPIC has proved beneficial not only to the SCAPE research community, but also to others who have used the information generated through the project.
