  6. Online multimedia teaching tool for Parkinson's disease.

    PubMed

    Misiaszek, Greg; Riconscente, Michelle; Henke, Maria; Walsh, John P

    2008-01-01

    We developed an online multimedia tool designed to enhance the student-learning environment in neurosciences through multi-sensory engagement. The combined use of scrolling text, narrations, and visual imagery engages multiple sensory modalities for effective learning, and it assists students in visualizing complex processes in the nervous system. The initial rollout of the online tool is for instruction in Parkinson's disease (PD), but its structure is flexible and can be used for teaching a variety of subjects. The instructor can access the tool online during lecture, and students can access the same information via the internet outside of class. In addition, each chapter is stand-alone and thus can be accessed online by other faculty or students to supplement other courses. Within each chapter or module, information is presented in outline format with greater detail accessible via sequential drop-down menus. This layering of related topics creates a spatial and motor-accessed path for learning. These multiple forms of engagement offer rich information representations to improve students' knowledge encoding, storing, and retrieval via multiple pathways. For instance, the tool includes student-controlled 2-D and 3-D animations, and video clip demonstrations of both patient case studies and on-campus research projects directly related to the subject material. Supplemental readings consist of current research articles (in Adobe Acrobat PDF file format) accessed within each educational topic. The teaching tool for PD is online at http://geroauen.usc.edu/Gero414_Beta/. PMID:23493487

  12. Utilizing multimedia tools for LRAM project documentation and marketing

    SciTech Connect

    Sullivan, R.G.; Hatton, P.D.; Boehm, A.

    1996-08-01

    Land Rehabilitation and Maintenance program managers at U.S. Army Training Installations must present technical material relating to LRAM projects to a variety of audiences, ranging from installation commanders to installation visitors and environmental interest groups. These audiences may play a role in approving and/or funding LRAM projects. Effective communication to these audiences can facilitate the achievement of LRAM program objectives. The rapid development of computer-based multimedia technology provides LRAM managers with powerful tools for creating highly effective project presentations that can be presented from notebook computers for use in briefings or distributed on CD-ROM for use on desktop computers. This paper presents an example of use of multimedia to document and present an LRAM revegetation project conducted at the Freiholser Forst Local Training Area in Germany. This CD-ROM presentation makes extensive use of digitized photos, video, maps, and text to present a detailed summary of the project, including project justification, background, methods, costs, and results. The application design allows the viewer to select topics of particular interest for detailed examination and to omit other topics or examine them in less detail. Virtually every important revegetation procedure is presented in photographs supplemented by brief video clips and text. Interactive charts allow easy comparison of alternative revegetation procedures that use different combinations of soil amendments, seedbed preparation, and seed mixes. Slide sequences and video clips clearly illustrate differences between conditions before and after the LRAM project was conducted. The presentation will be used to brief commanding officers, installation visitors, and host country officials about this highly successful LRAM project.

  15. [The new tools of microbiological diagnosis of tuberculosis].

    PubMed

    Guillet-Caruba, C; Martinez, V; Doucet-Populaire, F

    2014-12-01

    This review focuses on the role of new tools in the "modern" microbiological diagnosis of tuberculosis. Traditional techniques of microscopy and culture remain essential to diagnostic certainty, but some innovations replace daily the older techniques such as the identification of Mycobacterium tuberculosis complex by immunochromatography or mass spectrometry MALDI-TOF type from positive cultures, or susceptibility testing in liquid medium. New tools that use molecular techniques have become important. They all have in common to optimize the fight against tuberculosis by reducing diagnostic delay. They also allow rapid detection of drug resistance. However, the techniques of gene amplification directly from clinical samples are still less sensitive than culture. Bacteriological diagnosis of tuberculosis disease therefore still relies on the complementarities of different phenotypic and molecular techniques. PMID:25112804

  16. Single-Cell Microbiology: Tools, Technologies, and Applications

    PubMed Central

    Brehm-Stecher, Byron F.; Johnson, Eric A.

    2004-01-01

    The field of microbiology has traditionally been concerned with and focused on studies at the population level. Information on how cells respond to their environment, interact with each other, or undergo complex processes such as cellular differentiation or gene expression has been obtained mostly by inference from population-level data. Individual microorganisms, even those in supposedly “clonal” populations, may differ widely from each other in terms of their genetic composition, physiology, biochemistry, or behavior. This genetic and phenotypic heterogeneity has important practical consequences for a number of human interests, including antibiotic or biocide resistance, the productivity and stability of industrial fermentations, the efficacy of food preservatives, and the potential of pathogens to cause disease. New appreciation of the importance of cellular heterogeneity, coupled with recent advances in technology, has driven the development of new tools and techniques for the study of individual microbial cells. Because observations made at the single-cell level are not subject to the “averaging” effects characteristic of bulk-phase, population-level methods, they offer the unique capacity to observe discrete microbiological phenomena unavailable using traditional approaches. As a result, scientists have been able to characterize microorganisms, their activities, and their interactions at unprecedented levels of detail. PMID:15353569

  5. Individual-based modelling: an essential tool for microbiology.

    PubMed

    Ferrer, Jordi; Prats, Clara; López, Daniel

    2008-04-01

    Micro-organisms play a central role in every ecosystem and in the global biomass cycle. They are strongly involved in many fields of human interest, from medicine to the food industry and waste control. Nevertheless, most micro-organisms remain almost unknown, and nearly 99% of them have not yet been successfully cultured in vitro. Therefore, new approaches and new tools must be developed in order to understand the collective behaviour of microbial communities in any natural or artificial setting. In particular, theoretical and practical methodologies to deal with such systems at a mesoscopic level of description (covering the range from 100 to 10(8) cells) are required. Individual-based modelling (IBM) has become a widely used tool for describing complex systems made up of autonomous entities, such as ecosystems and social networks. Individual-based models (IBMs) provide some advantages over the traditional whole-population models: (a) they are bottom-up approaches, so they describe the behaviour of a system as a whole by establishing procedural rules for the individuals and for their interactions, and thus allow more realistic assumptions for the model of the individuals than population models do; (b) they permit the introduction of randomness and individual variability, so they can reproduce the diversity found in real systems; and (c) they can account for individual adaptive behaviour to their environmental conditions, so the evolution of the whole system arises from the dynamics that govern individuals in their pursuit of optimal fitness. However, they also present some drawbacks: they lack the clarity of continuous models and may easily become rambling, which makes them difficult to analyse and communicate. All in all, IBMs supply a holistic description of microbial systems and their emerging properties. They are specifically appropriate to deal with microbial communities in non-steady states, and spatially explicit IBMs are particularly appropriate to study

  6. A Usability Study of Users’ Perceptions Toward a Multimedia Computer-Assisted Learning Tool for Neuroanatomy

    Gould, Douglas J.; Terrell, Mark A.; Fleming, Jo

    2015-01-01

    This usability study evaluated users’ perceptions of a multimedia prototype for a new e-learning tool: Anatomy of the Central Nervous System: A Multimedia Course. Usability testing is a collection of formative evaluation methods that inform the developmental design of e-learning tools to maximize user acceptance, satisfaction, and adoption. Sixty-two study participants piloted the prototype and completed a usability questionnaire designed to measure two usability properties: program need and program applicability. Statistical analyses were used to test the hypothesis that the multimedia prototype was well designed and highly usable, it was perceived as: 1) highly needed across a spectrum of educational contexts, 2) highly applicable in supporting the pedagogical processes of teaching and learning neuroanatomy, and 3) was highly usable by all types of users. Three independent variables represented user differences: level of expertise (faculty vs. student), age, and gender. Analysis of the results supports the research hypotheses that the prototype was designed well for different types of users in various educational contexts and for supporting the pedagogy of neuroanatomy. In addition, the results suggest that the multimedia program will be most useful as a neuroanatomy review tool for health-professions students preparing for licensing or board exams. This study demonstrates the importance of integrating quality properties of usability with principles of human learning during the instructional design process for multimedia products. PMID:19177405

    Background International guidelines recommend the use of appropriate informed consent procedures in low literacy research settings because written information is not known to guarantee comprehension of study information. Objectives This study developed and evaluated a multimedia informed consent tool for people with low literacy in an area where a malaria treatment trial was being planned in The Gambia. Methods We developed the informed consent document of the malaria treatment trial into a multimedia tool integrating video, animations and audio narrations in three major Gambian languages. Acceptability and ease of use of the multimedia tool were assessed using quantitative and qualitative methods. In two separate visits, the participants’ comprehension of the study information was measured by using a validated digitised audio questionnaire. Results The majority of participants (70%) reported that the multimedia tool was clear and easy to understand. Participants had high scores on the domains of adverse events/risk, voluntary participation, study procedures while lowest scores were recorded on the question items on randomisation. The differences in mean scores for participants’ ‘recall’ and ‘understanding’ between first and second visits were statistically significant (F (1,41)=25.38, p<0.00001 and (F (1, 41) = 31.61, p<0.00001 respectively. Conclusions Our locally developed multimedia tool was acceptable and easy to administer among low literacy participants in The Gambia. It also proved to be effective in delivering and sustaining comprehension of study information across a diverse group of participants. Additional research is needed to compare the tool to the traditional consent interview, both in The Gambia and in other sub-Saharan settings. PMID:25133065

    The use of online learning tutorials to provide instruction in schools of nursing is growing in popularity; however, the outcomes associated with this method of instruction are not well documented. The focus of this experimental study, conducted at 2 universities in northern California, was to determine the effectiveness of an online interactive multimedia-learning tool versus text only, text and images, and multimedia learning explanations on math achievement, math self-efficacy, and student satisfaction. Compared to students in the control groups, students in the interactive multimedia group demonstrated equal posttest and retest knowledge of math; their math self-efficacy scores were also the same. Interactive multimedia group students were more satisfied with the method of learning, reported the technique to be enjoyable and more interesting, and provided sufficient feedback. An online interactive multimedia-learning tool is a realistic and creative method of teaching medication dosage calculations. PMID:15069846

    2011-01-01

    Digital technologies can improve student interest and knowledge in science. However, researching the vast number of websites devoted to science education and integrating them into undergraduate curricula is time-consuming. We developed an Adobe ColdFusion– and Adobe Flash–based system for simplifying the construction, use, and delivery of electronic educational materials in science. The Online Multimedia Teaching Tool (OMTT) in Neuroscience was constructed from a ColdFusion-based online interface, which reduced the need for programming skills and the time for curriculum development. The OMTT in Neuroscience was used by faculty to enhance their lectures in existing curricula. Students had unlimited online access to encourage user-centered exploration. We found the OMTT was rapidly adapted by multiple professors, and its use by undergraduate students was consistent with the interpretation that the OMTT improved performance on exams and increased interest in the field of neuroscience.

    2013-10-01

    This study aimed to provide early childhood special education professionals with a standardized and comprehensive language assessment tool for the early identification of language learning characteristics (e.g., hyperlexia) of young children with autism. In this study, we used computer technology to develop a multi-media online language assessment tool that presents auditory or visual stimuli. This online comprehensive language assessment consists of six subtests: decoding, homographs, auditory vocabulary comprehension, visual vocabulary comprehension, auditory sentence comprehension, and visual sentence comprehension. Three hundred typically developing children and 35 children with autism from Tao-Yuan County in Taiwan aged 4-6 participated in this study. The Cronbach α values of the six subtests ranged from .64 to .97. The variance explained by the six subtests ranged from 14% to 56%, the current validity of each subtest with the Peabody Picture Vocabulary Test-Revised ranged from .21 to .45, and the predictive validity of each subtest with WISC-III ranged from .47 to .75. This assessment tool was also found to be able to accurately differentiate children with autism up to 92%. These results indicate that this assessment tool has both adequate reliability and validity. Additionally, 35 children with autism have completed the entire assessment in this study without exhibiting any extremely troubling behaviors. However, future research is needed to increase the sample size of both typically developing children and young children with autism and to overcome the technical challenges associated with internet issues.

    The better understanding of the functioning of microbial communities is a challenging and crucial issue in the field of food microbiology, as it constitutes a prerequisite to the optimization of positive and technological microbial population functioning, as well as for the better control of pathogen contamination of food. Heterogeneity appears now as an intrinsic and multi-origin feature of microbial populations and is a major determinant of their beneficial or detrimental functional properties. The understanding of the molecular and cellular mechanisms behind the behavior of bacteria in microbial communities requires therefore observations at the single-cell level in order to overcome "averaging" effects inherent to traditional global approaches. Recent advances in the development of fluorescence-based approaches dedicated to single-cell analysis provide the opportunity to study microbial communities with an unprecedented level of resolution and to obtain detailed insights on the cell structure, metabolism activity, multicellular behavior and bacterial interactions in complex communities. These methods are now increasingly applied in the field of food microbiology in different areas ranging from research laboratories to industry. In this perspective, we reviewed the main fluorescence-based tools used for single-cell approaches and their concrete applications with specific focus on food microbiology. PMID:26163933

    2001-04-01

    Multimedia cases are perceived to be a means of bridging the gap between theory and practice in teacher education. However, little is known about how prospective teachers actually learn with these cases. In this paper, we examine how multimedia cases can stimulate reflective thought among preservice teachers. Gestalt psychology is employed as a theoretical lens to examine how seven preservice teachers work with a multimedia case. Data were collected by means of audiotaped work-aloud protocols, interviews and questionnaires. Results indicate that preservice teachers remain at low levels of abstraction of their ideas about teaching as a result of case examination. Directed assignments and collaboration among prospective teachers were a useful, but not always necessary, means of stimulating discussion on the multimedia case. The study leads to the conclusion there is still much to be learned about how prospective teachers interact with multimedia case, particularly about how such cases might stimulate reflective practice.

    Background: Diabetes self-management education is an essential element of diabetes care. Systems based on information and communication technology (ICT) for supporting lifestyle modification and self-management of diabetes are promising tools for helping patients better cope with diabetes. An earlier study had determined that diet improved and HbA1c declined for the patients who had used DialBetics during a 3-month randomized clinical trial. The objective of the current study was to test a more patient-friendly version of DialBetics, whose development was based on the original participants’ feedback about the previous version of DialBetics. Method: DialBetics comprises 4 modules: data transmission, evaluation, exercise input, and food recording and dietary evaluation. Food recording uses a multimedia food record, FoodLog. A 1-week pilot study was designed to determine if usability and compliance improved over the previous version, especially with the new meal-input function. Results: In the earlier 3-month, diet-evaluation study, HbA1c had declined a significant 0.4% among those who used DialBetics compared with the control group. In the current 1-week study, input of meal photos was higher than with the previous version (84.8 ± 13.2% vs 77.1% ± 35.1% in the first 2 weeks of the 3-month trial). Interviews after the 1-week study showed that 4 of the 5 participants thought the meal-input function improved; the fifth found input easier, but did not consider the result an improvement. Conclusions: DialBetics with FoodLog was shown to be an effective and convenient tool, its new meal-photo input function helping provide patients with real-time support for diet modification.

    2015-04-01

    Floods are a major, recurring source of harm to global economies and public health. Projected increases in the frequency and intensity of heavy precipitation events under future climate change, coupled with continued urbanization in areas with high risk of floods, may exacerbate future impacts of flooding. Improved flood risk management is essential to support global development, poverty reduction and public health, and is likely to be a crucial aspect of climate change adaptation. Importantly, floods can facilitate the transmission of waterborne pathogens by changing social conditions (overcrowding among displaced populations, interruption of public health services), imposing physical challenges to infrastructure (sewerage overflow, reduced capacity to treat drinking water), and altering fate and transport of pathogens (transport into waterways from overland flow, resuspension of settled contaminants) during and after flood conditions. Hydrological and hydrodynamic models are capable of generating quantitative characterizations of microbiological risks associated with flooding, while accounting for these diverse and at times competing physical and biological processes. Despite a few applications of such models to the quantification of microbiological risks associated with floods, there exists limited guidance as to the relative capabilities, and limitations, of existing modeling platforms when used for this purpose. Here, we review 17 commonly used flood and water quality modeling tools that have demonstrated or implicit capabilities of mechanistically representing and quantifying microbial risk during flood conditions. We compare models with respect to their capabilities of generating outputs that describe physical and microbial conditions during floods, such as concentration or load of non-cohesive sediments or pathogens, and the dynamics of high flow conditions. Recommendations are presented for the application of specific modeling tools for assessing

    In general multimedia is the combination of visual and audio representations. These representations could include elements of texts, graphic arts, sound, animation, and video. However, multimedia is restricted in such systems where information is digitalized and is processed by a computer. Interactive multimedia and hypermedia consist of multimedia applications that the user has more active role. Education is perhaps the most useful destination for multimedia and the place where multimedia has the most effective applications, as it enriches the learning process. Multimedia both in nursing education and in medical informatics education has several applications as well. A multimedia project can be developed even as a "stand alone" application (on CD-ROM), or on World Wide Web pages on Internet. However several technical constraints exist for developing multimedia applications on Internet. For developing multimedia projects we need hardware and software, talent and skill. The software requirements for multimedia development consist of one or more authoring systems and various editing applications for text, images, sounds and video. In this chapter different software tools for creating multimedia applications are presented. In the last part of this chapter, two examples of multimedia educational training programs are discussed. Both are "stand alone" applications (CD-ROMs). The first, examines several aspects of the electronic patient record by using videos, audio descriptions, lectures and glossary, while the second one presents several topics regarding epidemiology and epidemiological research by using graphics, sound and animation.

    Elucidating uncertainty and sensitivity structures in environmental models can be a difficult task, even for low-order, single-medium constructs driven by a unique set of site-specific data. Quantitative assessment of integrated, multimedia models that simulate hundreds of sites, spanning multiple geographical and ecological regions, will ultimately require a comparative approach using several techniques, coupled with sufficient computational power. The Framework for Risk Analysis in Multimedia Environmental Systems - Multimedia, Multipathway, and Multireceptor Risk Assessment (FRAMES-3MRA) is an important software model being developed by the United States Environmental Protection Agency for use in risk assessment of hazardous waste management facilities. The 3MRA modeling system includes a set of 17 science modules that collectively simulate release, fate and transport, exposure, and risk associated with hazardous contaminants disposed of in land-based waste management units (WMU) .

    Can web-based technology be used to effectively introduce or reinforce aspects of microbiology to middle school students? This central hypothesis examines whether brief exposure to a web adventure format containing virtual lab experiments and computer games within an engaging story line can impact student learning. An episodic adventure series, MedMyst (http://medmyst.rice.edu), focuses on infectious diseases and the microbes that cause them. The website is not intended to replace classroom instruction, but rather to engage students in problem-solving activities not likely to be encountered elsewhere. It also provides scientists with a resource to introduce microbiology to adolescent audiences through outreach activities. In the online adventure, the player (student) enters a futuristic world in which he or she becomes a "Reconstructor," a member of an elite team charged with preventing the spread of infectious disease. The series consists of three "missions," each lasting approximately 30 to 40 minutes and designed to address a limited set of learning objectives. Middle school students participated in the creation of the characters and the stylized design through focus groups. Classroom teachers oversaw the alignment of the web adventure objectives with the National Science Content Standards. Scientists and clinicians reviewed the web adventure for content and accuracy. A field test involving over 700 students from nine different schools assessed the knowledge gains attributable to playing MedMyst. Gain scores from pretest to posttest indicated that middle school students retained important information by interacting with the online material for as little as 30 minutes per adventure; however, gains for high school students were less persuasive, perhaps indicating a different learning tool or content is required for this age audience.

    2013-04-01

    In the last few years science education moved forward rapidly by connecting the expertise and enthusiasm of polar educators worldwide. The interest in Polar Sciences determined the creation of a global professional network for those that educate in, for, and about the Polar Regions. In Italy, this cooperation is well represented by APECS-Italy, the Italian section of the Association of Polar Early Career Scientists (APECS) that is composed by young researchers and teachers of the Italian School. The Polar Regions represent one of the best natural environments where students can investigate directly on global changes. In this sense, the working group UNICAMearth of the Geology Division of School of Science and Technology, University of Camerino (Italy), promotes the arrangement of instructional resources based on real data coming from the research world. Our project aims to develop innovative teaching resources and practices designed to bring the importance of the Polar Regions closer to home. Consequently, Polar Sciences could become a focus point in the new national school curricula, where Earth Sciences have to be thought and learnt in an integrated way together with other sciences. In particular, M. Macario is producing a teaching tool package, starting from a case study, which includes a dozen of full lesson plans based on multimedia tools (images, smart board lessons and videos of lab experiments) as well as on hands-on activities about polar issues and phenomena. Among the resources the teaching tool package is referring to, there is also an App for tablet named CLAST (CLimate in Antartica from Sediments and Tectonics). This App has been designed by a team made up of polar scientists belonging to the University of Siena and University of Padova, two science teachers of the Museo delle Scienze (MUSE) of Trento other than M. Macario. CLAST has been funded by two Research Projects, CLITEITAM ("CLImate-TEctonics Interactions along the TransAntarctic Mountains

    Asthma 1-2-3 is a newly-developed low-literacy multimedia education tool designed to promote asthma self-care concepts among African American adults. An expert panel (n = 10) informed content development for the tool. The video script and storyboard imagery were shown to 30 African Americans recruited from the American Lung Association, whose reactions and comments guided further revisions. The final version was pilot tested in three diverse community settings in Chicago to determine the efficacy of Asthma 1-2-3 at improving patient understanding of asthma and its symptoms. In all, 130 adults participated in the pilot test. Knowledge scores significantly improved from pretest to posttest following presentation of the developed tool for subjects across all literacy levels (Pretest: Mean = 4.2 [SD = 1.6]; Posttest: M = 6.8 [SD = 2.0], P < 0.001). Symptom pathophysiology concepts were the least understood. Individuals with low literacy had less total knowledge score gains compared to those with marginal and adequate literacy (1.8, 2.6, and 3.2 respectively; P = 0.002). The multimedia tool significantly improved understanding of asthma. Individuals with limited literacy may require additional instruction, repeated viewing, or added tangible cues (i.e. supplementary print materials) to support knowledge retention. In general, feedback from the target population was particularly helpful in the development of the tool and its initial evaluation, and should be considered as a necessary step in the creation of other patient education materials.

    Undoubtedly, multimedia electronic mail has many advantages in exchanging information electronically in a collaborative work. The existing design of e-mail systems architecture is inefficient in exchanging multimedia message which has much larger volume, and requires more bandwidth and storage space than the text-only messages. This paper presents an innovative method for exchanging multimedia mail messages in a heterogeneous environment to support collaborative work over YAW on the Internet. We propose a {open_quotes}Parcel Collection{close_quotes} approach for exchanging multimedia electronic mail messages. This approach for exchanging multimedia electronic mail messages integrates the current WWW technologies with the existing electronic mail systems.

    methods is continuously increasing. For example, microbiological and molecular tools showed the presence and activity of halorespiring bacteria in sediment samples of the Yangtze river, China. PCR-detection demonstrated the presence of five different halorespiring bacterial groups as well as of four different dechlorinating enzymes of Dehalococcoides. In conclusion, our study demonstrates that (i) multiple lines of evidence approaches result in a profound understanding of the biodegradation processes occurring in the field, (ii) stable isotope fractionation is suitable for assessing and quantifying anaerobic and aerobic chloroethene degradation and (iii) detection and quantification of dechlorinating bacteria and enzymes by PCR methods provide more insight into biodegradation processes.

    Recent advances in DNA sequencing technologies have the potential to transform the field of clinical and public health microbiology, and in the last few years numerous case studies have demonstrated successful applications in this context. Among other considerations, a lack of user-friendly data analysis and interpretation tools has been frequently cited as a major barrier to routine use of these techniques. Here we consider the requirements of microbiology laboratories for the analysis, clinical interpretation and management of bacterial whole-genome sequence (WGS) data. Then we discuss relevant, existing WGS analysis tools. We highlight many essential and useful features that are represented among existing tools, but find that no single tool fulfils all of the necessary requirements. We conclude that to fully realise the potential of WGS analyses for clinical and public health microbiology laboratories of all scales, we will need to develop tools specifically with the needs of these laboratories in mind.

    We examined the bacterial accumulation and digestion in the alien polychaete Branchiomma bairdi. Microbiological analyses were performed on worm homogenates from "unstarved" and "starved" individuals and on seawater from the same sampling site (Ionian Sea, Italy). Densities of culturable heterotrophic bacteria (22 °C), total culturable bacteria (37 °C) and vibrios were measured on Marine Agar 2216, Plate Count Agar and TCBS Agar, respectively. Microbial pollution indicators were determined by the most probable number method. B. bairdi was able to accumulate all the six considered microbiological groups which, however, differ in their resistance to digestion. B. bairdi results more efficient than the other two co-occurring sabellids in removing bacteria suggesting that it may counteract the effects of microbial pollution playing a potential role for in situ bioremediation. Thus a potential risk, such as the invasion of an alien species, could be transformed into a benefit with high potential commercial gain and economic feasibility. PMID:25070411

    Food safety is essential in mass catering. In Europe, Regulation (EC) No. 852/2004 requires food business operators to put in place, implement and maintain permanent procedures based on Hazard Analysis and Critical Control Point (HACCP) principles. Each HACCP plan is specifically implemented for the processing plant and processing methods and requires a systematic collection of data on the incidence, elimination, prevention, and reduction of risks. In this five-year-study, the effectiveness of the HACCP plan of a University canteen was verified through periodic internal auditing and microbiological monitoring of meals, small equipment, cooking tools, working surfaces, as well as hands and white coats of the canteen staff. The data obtained revealed no safety risks for the consumers, since Escherichia coli, Salmonella spp. and Listeria monocytogenes were never detected; however, a quite discontinuous microbiological quality of meals was revealed. The fluctuations in the microbial loads of mesophilic aerobes, coliforms, Staphylococcus aureus, Bacillus cereus, and sulphite-reducing clostridia were mainly ascribed to inadequate handling or processing procedures, thus suggesting the need for an enhancement of staff training activities and for a reorganization of tasks. Due to the wide variety of the fields covered by internal auditing, the full conformance to all the requirements was never achieved, though high scores, determined by assigning one point to each answer which matched with the requirements, were achieved in all the years.

    The effects of interventions such as sanitation or hand hygiene on hand contamination are difficult to evaluate. We explored the ability of a simple microbiological test to: (1) detect recontamination after handwashing; (2) reflect risk factors for microbial contamination and (3) be applicable to large populations. The study was done in rural Andhra Pradesh, India, and Maputo, Mozambique. Participants placed all 10 fingertips on a chromogenic agar that stains Enterococcus spp. and E. coli spp. Outcomes were the number of colonies and the number of fingertips with colonies. In the recontamination study, participants were randomised to handwashing with soap and no handwashing, and tested at 30 min intervals afterwards. In two cross sectional studies, risk factors for hand contamination were explored. Recontamination of hands after washing with soap was fast, with baseline levels reached after 1 h. Child care was associated with higher Enterococcus spp. counts, whereas agricultural activities increased E. coli spp. counts. Food preparation was associated with higher counts for both organisms. In Maputo, counts were not strongly associated with water access, latrine type, education or diarrhoea. The method seems unsuitable for the evaluation of handwashing promotion. It may reflect immediately preceding risk practices but not household-level risk factors. PMID:25407420

  12. The New Face of Genetics: Creating A Multimedia Educational Tool for the Twenty-First Century

    NASA Astrophysics Data System (ADS)

    Fan, Audrey

    In the study of certain genetic conditions, it is important to understand the specific "dysmorphology" associated with them. This describes the unique anatomical manifestations of the genetic condition. Traditionally, students learn about dysmorphology by reading text descriptions or looking at photographs of affected individuals. The New Face of Genetics is a film project that aims to teach students dysmorphology by featuring people who have specific genetic conditions. The goal is to enhance students' understanding of these conditions as well as to impart the humanity and beauty of the people who appear in the film. Students will have the opportunity to see dysmorphic features on the animated human form as well as meet individuals who are living with genetic difference. The target audience includes genetic counseling students and other medical professionals. Three short films were made in this format to demonstrate how this type of educational tool can be made. The featured conditions were Marfan syndrome, Sturge-Weber syndrome and Joubert syndrome. Future work will be carried out by other genetic counseling students who will make additional films based on our templates. A compendium of approximately 20 films will be eventually completed and released to genetic counseling programs and medical schools.

  13. Use of RE-AIM to develop a multi-media facilitation tool for the patient-centered medical home

    PubMed Central

    2011-01-01

    Background Much has been written about how the medical home model can enhance patient-centeredness, care continuity, and follow-up, but few comprehensive aids or resources exist to help practices accomplish these aims. The complexity of primary care can overwhelm those concerned with quality improvement. Methods The RE-AIM planning and evaluation model was used to develop a multimedia, multiple-health behavior tool with psychosocial assessment and feedback features to facilitate and guide patient-centered communication, care, and follow-up related to prevention and self-management of the most common adult chronic illnesses seen in primary care. Results The Connection to Health Patient Self-Management System, a web-based patient assessment and support resource, was developed using the RE-AIM factors of reach (e.g., allowing input and output via choice of different modalities), effectiveness (e.g., using evidence-based intervention strategies), adoption (e.g., assistance in integrating the system into practice workflows and permitting customization of the website and feedback materials by practice teams), implementation (e.g., identifying and targeting actionable priority behavioral and psychosocial issues for patients and teams), and maintenance/sustainability (e.g., integration with current National Committee for Quality Assurance recommendations and clinical pathways of care). Connection to Health can work on a variety of input and output platforms, and assesses and provides feedback on multiple health behaviors and multiple chronic conditions frequently managed in adult primary care. As such, it should help to make patient-healthcare team encounters more informed and patient-centered. Formative research with clinicians indicated that the program addressed a number of practical concerns and they appreciated the flexibility and how the Connection to Health program could be customized to their office. Conclusions This primary care practice tool based on an

    PubMed Central

    Wilson, John W.; Marshall, William F.; Estes, Lynn L.

    2011-01-01

    We developed a computerized medical informatics tool to identify patients who had a culture performed on a sterile body site specimen during their hospitalization that subsequently turned positive after hospital dismissal. During a 13-month period, 533 patients had a positive culture identified by our Computer-Based Antimicrobial Monitoring (CBAM) program after hospital dismissal, and 112 (21%) of these culture results necessitated an intervention and communication with the primary health care professional. Thirty-two (29%) of positive cultures were from the blood. Thirty-eight (34%) of the CBAM interventions with available outcome data resulted in initiation of, change in, or prolongation of outpatient antimicrobial therapy. The CBAM program serves an important role in optimizing patient care and communication with the health care professional during the transition from inpatient to outpatient management. PMID:22134937

  19. Single-stranded DNA phages: from early molecular biology tools to recent revolutions in environmental microbiology.

    PubMed

    Székely, Anna J; Breitbart, Mya

    2016-03-01

    Single-stranded DNA (ssDNA) phages are profoundly different from tailed phages in many aspects including the nature and size of their genome, virion size and morphology, mutation rate, involvement in horizontal gene transfer, infection dynamics and cell lysis mechanisms. Despite the importance of ssDNA phages as molecular biology tools and model systems, the environmental distribution and ecological roles of these phages have been largely unexplored. Viral metagenomics and other culture-independent viral diversity studies have recently challenged the perspective of tailed, double-stranded DNA (dsDNA) phages, dominance by demonstrating the prevalence of ssDNA phages in diverse habitats. However, the differences between ssDNA and dsDNA phages also substantially limit the efficacy of simultaneously assessing the abundance and diversity of these two phage groups. Here we provide an overview of the major differences between ssDNA and tailed dsDNA phages that may influence their effects on bacterial communities. Furthermore, through the analysis of 181 published metaviromes we demonstrate the environmental distribution of ssDNA phages and present an analysis of the methodological biases that distort their study through metagenomics.

    2015-01-01

    The selection of multiresistant microorganisms, as a side-effect of the use of antimicrobials, together with the lack of new therapeutic drugs expected in the near future, forces to a rational use of antibiotics. The optimisation of antibacterial treatments based on pharmacokinetic/pharmacodynamic analysis (PK/PD) may contribute to prolong the life of antibiotics and to contain the bacterial resistance to them. A review is made of the importance of the appropriateness of the dose regimen selected, the application of PK/PD analysis of antimicrobials, the Monte Carlo simulation, PK/PD indices for efficacy, and PK/PD cut-off points. PK/PD analysis is also applicable to the prevention of bacterial resistance. Different methods have been used to study the factors that lead to its emergence and spread, such as in vitro and animal models, and resistance prevention studies (mutant selection window). Although the PK/PD analysis is a very useful tool for the selection of the most appropriate dose regimen of antibiotics, several problems limit its use in clinical practice. PMID:23850188

    SUMMARY The clinical microbiology laboratory has responsibilities ranging from characterizing the causative agent in a patient's infection to helping detect global disease outbreaks. All of these processes are increasingly becoming partnered more intimately with informatics. Effective application of informatics tools can increase the accuracy, timeliness, and completeness of microbiology testing while decreasing the laboratory workload, which can lead to optimized laboratory workflow and decreased costs. Informatics is poised to be increasingly relevant in clinical microbiology, with the advent of total laboratory automation, complex instrument interfaces, electronic health records, clinical decision support tools, and the clinical implementation of microbial genome sequencing. This review discusses the diverse informatics aspects that are relevant to the clinical microbiology laboratory, including the following: the microbiology laboratory information system, decision support tools, expert systems, instrument interfaces, total laboratory automation, telemicrobiology, automated image analysis, nucleic acid sequence databases, electronic reporting of infectious agents to public health agencies, and disease outbreak surveillance. The breadth and utility of informatics tools used in clinical microbiology have made them indispensable to contemporary clinical and laboratory practice. Continued advances in technology and development of these informatics tools will further improve patient and public health care in the future. PMID:25278581

    MERLIN-Expo is a library of models that was developed in the frame of the FP7 EU project 4FUN in order to provide an integrated assessment tool for state-of-the-art exposure assessment for environment, biota and humans, allowing the detection of scientific uncertainties at each step of the exposure process. This paper describes the main features of the MERLIN-Expo tool. The main challenges in exposure modelling that MERLIN-Expo has tackled are: (i) the integration of multimedia (MM) models simulating the fate of chemicals in environmental media, and of physiologically based pharmacokinetic (PBPK) models simulating the fate of chemicals in human body. MERLIN-Expo thus allows the determination of internal effective chemical concentrations; (ii) the incorporation of a set of functionalities for uncertainty/sensitivity analysis, from screening to variance-based approaches. The availability of such tools for uncertainty and sensitivity analysis aimed to facilitate the incorporation of such issues in future decision making; (iii) the integration of human and wildlife biota targets with common fate modelling in the environment. MERLIN-Expo is composed of a library of fate models dedicated to non biological receptor media (surface waters, soils, outdoor air), biological media of concern for humans (several cultivated crops, mammals, milk, fish), as well as wildlife biota (primary producers in rivers, invertebrates, fish) and humans. These models can be linked together to create flexible scenarios relevant for both human and wildlife biota exposure. Standardized documentation for each model and training material were prepared to support an accurate use of the tool by end-users. One of the objectives of the 4FUN project was also to increase the confidence in the applicability of the MERLIN-Expo tool through targeted realistic case studies. In particular, we aimed at demonstrating the feasibility of building complex realistic exposure scenarios and the accuracy of the

    Documentaries related to Astronomy and Planetary Sciences are a common and very attractive way to promote the interest of the public in these areas. These educational tools can get benefit from new advanced computer animation software and 3D technologies, as these allow making these documentaries even more attractive. However, special care must be taken in order to guarantee that the information contained in them is serious and objective. In this sense, an additional value is given when the footage is produced by the own researchers. With this aim, a new documentary produced and directed by Prof. Madiedo has been developed. The documentary, which has been entirely developed by means of advanced computer animation tools, is dedicated to several aspects of Meteor Science and Meteoritics. The main features of this outreach and education initiative are exposed here.

    Stroke is a major cause of adult disability. The Interdisciplinary Comprehensive Arm Rehabilitation Evaluation (I-CARE) clinical trial aims to evaluate a therapy for arm rehabilitation after stroke. A primary outcome measure is correlative analysis between stroke lesion characteristics and standard measures of rehabilitation progress, from data collected at seven research facilities across the country. Sharing and communication of brain imaging and behavioral data is thus a challenge for collaboration. A solution is proposed as a web-based system with tools supporting imaging and informatics related data. In this system, users may upload anonymized brain images through a secure internet connection and the system will sort the imaging data for storage in a centralized database. Users may utilize an annotation tool to mark up images. In addition to imaging informatics, electronic data forms, for example, clinical data forms, are also integrated. Clinical information is processed and stored in the database to enable future data mining related development. Tele-consultation is facilitated through the development of a thin-client image viewing application. For convenience, the system supports access through desktop PC, laptops, and iPAD. Thus, clinicians may enter data directly into the system via iPAD while working with participants in the study. Overall, this comprehensive imaging informatics system enables users to collect, organize and analyze stroke cases efficiently.

    With the growing presence of multimedia-enabled systems, one will see an integration of collaborative computing concepts into the everyday environments of future scientific and technical workplaces. Desktop teleconferencing is in common use today, while more complex desktop teleconferencing technology that relies on the availability of multipoint (greater than two nodes) enabled tools is now starting to become available on PCs. A critical problem when using these collaboration tools is the inability to easily archive multistream, multipoint meetings and make the content available to others. Ideally one would like the ability to capture, record, playback, index, annotate and distribute multimedia stream data as easily as one currently handles text or still image data. While the ultimate goal is still some years away, the Argonne Voyager project is aimed at exploring and developing media server technology needed to provide a flexible virtual multipoint recording/playback capability. In this article the authors describe the motivating requirements, architecture implementation, operation, performance, and related work.

    Our team in Europe has developed the routine clinical laboratory identification of microorganisms by matrix-assisted laser desorption ionization time-of-flight (MALDI-TOF) mass spectrometry (MS). To evaluate the utility of MALDI-TOF MS in tropical Africa in collaboration with local teams, we installed an apparatus in the Hôpital Principal de Dakar (Senegal), performed routine identification of isolates, and confirmed or completed their identification in France. In the case of discordance or a lack of identification, molecular biology was performed. Overall, 153/191 (80.1%) and 174/191 (91.1%) isolates yielded an accurate and concordant identification for the species and genus, respectively, with the 2 different MALDI-TOF MSs in Dakar and Marseille. The 10 most common bacteria, representing 94.2% of all bacteria routinely identified in the laboratory in Dakar (Escherichia coli, Klebsiella pneumoniae, Streptococcus agalactiae, Acinetobacter baumannii, Pseudomonas aeruginosa, Staphylococcus aureus, Staphylococcus haemolyticus, Enterobacter cloacae, Enterococcus faecalis, and Staphylococcus epidermidis) were accurately identified with the MALDI-TOF MS in Dakar. The most frequent misidentification in Dakar was at the species level for Achromobacter xylosoxidans, which was inaccurately identified as Achromobacter denitrificans, and the bacteria absent from the database, such as Exiguobacterium aurientacum or Kytococcus schroeteri, could not be identified. A few difficulties were observed with MALDI-TOF MS for Bacillus sp. or oral streptococci. 16S rRNA sequencing identified a novel bacterium, “Necropsobacter massiliensis.” The robust identification of microorganisms by MALDI-TOF MS in Dakar and Marseille demonstrates that MALDI-TOF MS can be used as a first-line tool in clinical microbiology laboratories in tropical countries.

The second phase of the project adds network support to the courseware in the form of the network tutoring and networked supply chain support. One year into the project specifications for developing multimedia have been made and can be found in the project's deliverables. Also a summary of good practice in multimedia courseware development has been drawn up. First phase demonstrators (converted text based courses) are currently being prepared. This article starts with a global overview of the TALENT project itself. In more detail an overview of best practice guidelines in multimedia courseware development will be given. The information shown was obtained from an extensive survey among experts in the field of computer based training. The survey was conducted early this year as part of one of the project's deliverables. Finally some comments will be made on a multimedia demonstrator which is currently under development at HISCOM.

  19. Leveraging the power of Web 2.0 tools: a wiki platform as a multimedia teaching and learning environment in dental education.

    PubMed

    Salajan, Florin D; Mount, Greg J

    2012-04-01

    This article presents the development and implementation of a wiki-based application for the delivery of educational content in dentistry. The Dental Procedure Education System (DPES) is a new web application that uses SharePoint to combine online collaborative authoring characteristic of wiki spaces with instructional video documentaries. Harnessing the wiki's versatility, DPES offers faculty members an avenue to develop an authoritative source of information for both students, through DPES Pro, and the public at large, through DPES Public. Principles of cognitive theory of multimedia learning, constructivist theory, and collaborative writing were employed in the development of DPES. An authoring protocol, with a clearly defined sequence of steps, was established in order to keep the production of the DPES procedures consistent and predictable. Initial, anecdotal user reports indicate that DPES is well received among dental students and faculty members. Expected outcomes and benefits of DPES use are discussed, and directions for research are proposed. PMID:22473554

  7. Controlling QoS in a collaborative multimedia environment

    SciTech Connect

    Alfano, M.; Sigle, R.

    1996-12-31

    A collaborative multimedia environment allows users to work remotely on common projects by sharing applications (e.g., CAD tools, text editors, white boards) and simultaneously communicate audiovisually. Several dedicated applications (e.g., MBone tools) exist for transmitting video, audio and data between users. Due to the fact that they have been developed for the Internet which does not provide any Quality of Service (QoS) guarantee, these applications do not or only partially support specification of QoS requirements by the user. In addition, they all come with different user interfaces. In this paper we first discuss the problems that we experienced both at the host and network levels when executing a multimedia application and varying its resource requirements. We then present the architectural details of a collaborative multimedia environment (CME) that we have been developing in order to help a user to set up and control a collaborative multimedia session.

    Shae, Zon-Yin; Wang, Xiping; von Kaenel, Juerg

    2000-05-01

    Advertising in TV broadcasting has shown that multimedia is a very effective means to present merchandise and attract shoppers. This has been applied to the Web by including animated multimedia banner ads on web pages. However, the issues of coupling interactive browsing, shopping, and secure transactions e.g. from inside a multimedia banner, have only recently started to being explored. Currently there is an explosively growing amount of back-end services available (e.g., business to business commerce (B2B), business to consumer (B2C) commerce, and infomercial services) in the Internet. These services are mostly accessible through static HTML web pages at a few specific web portals. In this paper, we will investigate the feasibility of using interactive multimedia banners as pervasive access point for the B2C, B2B, and infomercial services. We present a system architecture that involves a layer of middleware agents functioning as the bridge between the interactive multimedia banners and back-end services.

  9. The effects of using screencasting as a multimedia pre-training tool to manage the intrinsic cognitive load of chemical equilibrium instruction for advanced high school chemistry students

    NASA Astrophysics Data System (ADS)

    Musallam, Ramsey

    Chemistry is a complex knowledge domain. Specifically, research notes that Chemical Equilibrium presents greater cognitive challenges than other topics in chemistry. Cognitive Load Theory describes the impact a subject, and the learning environment, have on working memory. Intrinsic load is the facet of Cognitive Load Theory that explains the complexity innate to complex subjects. The purpose of this study was to build on the limited research into intrinsic cognitive load, by examining the effects of using multimedia screencasts as a pre-training technique to manage the intrinsic cognitive load of chemical equilibrium instruction for advanced high school chemistry students. A convenience sample of 62 fourth-year high school students enrolled in an advanced chemistry course from a co-ed high school in urban San Francisco were given a chemical equilibrium concept pre-test. Upon conclusion of the pre-test, students were randomly assigned to two groups: pre-training and no pre-training. The pre-training group received a 10 minute and 52 second pre-training screencast that provided definitions, concepts and an overview of chemical equilibrium. After pre-training both group received the same 50-minute instructional lecture. After instruction, all students were given a chemical equilibrium concept post-test. Independent sample t-tests were conducted to examine differences in performance and intrinsic load. No significant differences in performance or intrinsic load, as measured by ratings of mental effort, were observed on the pre-test. Significant differences in performance, t(60)=3.70, p=.0005, and intrinsic load, t(60)=5.34, p=.0001, were observed on the post-test. A significant correlation between total performance scores and total mental effort ratings was also observed, r(60)=-0.44, p=.0003. Because no significant differences in prior knowledge were observed, it can be concluded that pre-training was successful at reducing intrinsic load. Moreover, a significant

    2002-01-01

    The deterministic multimedia dose/risk assessment codes RESRAD and RESRAD-BUILD have been widely used for many years for evaluation of sites contaminated with residual radioactive materials. The RESRAD code applies to the cleanup of sites (soils) and the RESRAD-BUILD code applies to the cleanup of buildings and structures. This work describes the procedure used to enhance the deterministic RESRAD and RESRAD-BUILD codes for probabilistic dose analysis. A six-step procedure was used in developing default parameter distributions and the probabilistic analysis modules. These six steps include (1) listing and categorizing parameters; (2) ranking parameters; (3) developing parameter distributions; (4) testing parameter distributions for probabilistic analysis; (5) developing probabilistic software modules; and (6) testing probabilistic modules and integrated codes. The procedures used can be applied to the development of other multimedia probabilistic codes. The probabilistic versions of RESRAD and RESRAD-BUILD codes provide tools for studying the uncertainty in dose assessment caused by uncertain input parameters. The parameter distribution data collected in this work can also be applied to other multimedia assessment tasks and multimedia computer codes.

    2001-07-01

    Current well-known web browsers are limited to graphical User Interfaces (GUIs) that are geared towards an iconic or hieroglyphic system of communication. Modern speech-enabled user interfaces are built over GUIs and apply a 'Say What You See' (SWYS) paradigm. GUIs and SWYS fail to satisfy the user's need for natural language multimedia interfaces. The first voice based OS interfaces such as the Vocal/Auditory Multimedia Browser (VAMB) combined a spoken quasi-natural language input with a graphical display, audio and verbal output and supported a rudimentary browsing capability. The MultiMedia Browser (MMB) improves VAMB's speech recognition capabilities and includes a complete web browser with advanced page navigation. MMB applies a What You Say Is What You Get (WYSIWYG) paradigm that utilizes both an Associative Calculus Environment (ACE) and Dynamic Hierarchal Limited Vocabulary (DHLV). The associative calculus is a set of rules that specifies how sentences using the ACE syntax are to be interpreted relative to graphical displays. DHLV dynamically minimizes the contents of the vocabulary pool depending on the current multimedia configuration.

    2008-05-01

    The goal of the Virtual Astronomy Multimedia Project (VAMP) is to promote and vastly multiply the use of astronomy multimedia resources—from images and illustrations to animations, movies, and podcasts—and enable innovative future exploitation of a wide variety of outreach media by systematically linking resource archives worldwide. High-quality astronomical images, accompanied by rich caption and background information, abound on the web and yet prove notoriously difficult to locate efficiently using existing search tools. The Virtual Astronomy Multimedia Project offers a solution via the Astronomy Visualization Metadata (AVM) standard. Due to roll out in time for IYA2009, VAMP manages the design, implementation, and dissemination of the AVM standard for the education and public outreach astronomical imagery that observatories publish. VAMP will support implementations in World Wide Telescope, Google Sky, Portal to the Universe, and 365 Days of Astronomy, as well as Uniview and DigitalSky software designed specifically for planetariums. The VAMP workshop will introduce the AVM standard and describe its features, highlighting sample image tagging processes using diverse tools—the critical first step in getting media into VAMP. Participants with laptops will have an opportunity to experiment first hand, and workshop organizers will update a web page with system requirements and software options in advance of the conference (see http://virtualastronomy.org/ASP2008/ for links to resources). The workshop will also engage participants in a discussion and review of the innovative AVM image hierarchy taxonomy, which will soon be extended to other types of media.

    1990-08-01

    Electronic mail is a facility, analogous to postal mail, in which computers are used to compose, deliver, and receive messages. Traditional electronic mail systems rely solely on text as the medium of communication. A multi-media electronic mall application, Mail, combines the media of Rich Text, voice, images, and electronic documents to facilitate interpersonal communication. With Mail, these various media can be integrated into a single message. The variety of available media and the complexity of the messages that result from their combination make it important for Mail to have a simple user interface. It was possible to develop a simple, graphically-based interface that would accommodate Mail's message complexity. The integration of these diverse media is made practical by the rich operating environment in which Mail runs. Modern advances in hardware, operating systems, libraries, and servers make possible this powerful multi-media electronic mail application.

    SciTech Connect

    Soesilo, J.A.; Wiley, W.D.

    1999-09-01

    This book explores and supports the argument that effective environmental management must be based on a multimedia approach, which focuses simultaneously on air, water, and waste and enables managers to assess the resulting financial, operation, and management benefits. The multimedia approach, which can be used to design an effective compliance program, includes proper waste and material handling management, systematic monitoring, and record keeping requirements. This approach integrates a wide array of environmental requirements and decision processes, which the authors examine in sixteen chapters, organized into four parts: the role of environmental management; environmental aspects of business operation, environmental processes; and environmental management trends. Within these parts, the authors highlight the development of modern environmental management and provide an overview of federal laws pertinent to multimedia environmental management. They examine such issues as chemical storage and transportation, tank system operations and requirements, waste determination, spill response procedures, and employee training. Environmental processes addressed in the book include the management of solid and hazardous waste, wastewater treatment systems, stormwater management, air emission control, and site remediation. The authors also briefly discuss significant initiatives in US environmental management and look toward corporate sustainable development.

    2002-09-01

    The application of information technology to health care has generated growing concern about the privacy and security of medical information. Furthermore, data and communication security requirements in the field of multimedia are higher. In this paper we describe firstly the most important security requirements that must be fulfilled by multimedia medical data, and the security measures used to satisfy these requirements. These security measures are based mainly on modern cryptographic and watermarking mechanisms as well as on security infrastructures. The objective of our work is to complete this picture, exploiting the capabilities of multimedia medical data to define and implement an authorization model for regulating access to the data. In this paper we describe an extended role-based access control model by considering, within the specification of the role-permission relationship phase, the constraints that must be satisfied in order for the holders of the permission to use those permissions. The use of constraints allows role-based access control to be tailored to specifiy very fine-grained and flexible content-, context- and time-based access control policies. Other restrictions, such as role entry restriction also can be captured. Finally, the description of system architecture for a secure DBMS is presented. PMID:12507263

    1995-11-01

    The demand for digital radiological imaging and archiving applications has been increasingly rapidly. These digital applications offer significant advantages to the physician over the traditional film-based technique. They result in faster and better quality services, support remote access and conferencing capabilities, provide on demand service availability, eliminate film processing costs, and most significantly, they are suitable services for the evolving global information super highway. Several existing medical multimedia systems incorporate and utilize those advanced technical features. However, radiologists are seeking an order of magnitude improvement in the overall current system design and performance indices (such as transactions response times, system utilization and throughput). One of the main technical concern radiologists are raising is the miss-filing occurrence. This even will decrease the radiologist productivity; introduce unnecessarily workload; and will result in total customer dissatisfaction. This paper presents Multimedia Medical Archiving System, which can be used in hospitals and medical centers for storing and retrieving radiological images. Furthermore, this paper emphasizes a viable solution for the miss-filing problem. The results obtained demonstrate and quantify the improvement in the overall radiological operations. Specifically this paper demonstrates an order of 80% improvement in the response time for retrieving images. This enhancement in system performance directly translates to a tremendous improvement in the radiologist's productivity.

  15. Cost analysis in a clinical microbiology laboratory.

    PubMed

    Brezmes, M F; Ochoa, C; Eiros, J M

    2002-08-01

    The use of models for business management and cost control in public hospitals has led to a need for microbiology laboratories to know the real cost of the different products they offer. For this reason, a catalogue of microbiological products was prepared, and the costs (direct and indirect) for each product were analysed, along with estimated profitability. All tests performed in the microbiology laboratory of the "Virgen de la Concha" Hospital in Zamora over a 2-year period (73192 tests) were studied. The microbiological product catalogue was designed using homogeneity criteria with respect to procedures used, workloads and costs. For each product, the direct personnel costs (estimated from workloads following the method of the College of American Pathologists, 1992 version), the indirect personnel costs, the direct and indirect material costs and the portion of costs corresponding to the remaining laboratory costs (capital and structural costs) were calculated. The average product cost was 16.05 euros. The average cost of a urine culture (considered, for purposes of this study, as a relative value unit) reached 13.59 euros, with a significant difference observed between positive and negative cultures (negative urine culture, 10.72 euros; positive culture, 29.65 euros). Significant heterogeneity exists, both in the costs of different products and especially in the cost per positive test. The application of a detailed methodology of cost analysis facilitates the calculation of the real cost of microbiological products. This information provides a basic tool for establishing clinical management strategies. PMID:12226688

A collaborative workspace is a virtual data space shared between medical experts for working out solutions collaboratively while conferencing. Our approach provides medical users with an integrated view of various kinds of multimedia patient data and a unified control over the workspace. For data navigation and conferencing, a tree-like navigation tool, which we named the patient record tree, is provided. And we classify patient data, which is the object of medical collaborative works, into six basic types, and provide a view template for displaying each of these types. PMID:10384472

    Gladwell, S.; Gottlieb, E.J.; McDonald, M.J.; Slutter, C.L.

    1998-12-15

    The World Wide Web has become a key tool for information sharing. Engineers and scientists are finding that the web is especially suited to publishing the graphical, multi-layered information that is typical of their work. Web pages are easier to distribute than hardcopy. Web movies have become more accessible, in many offices, than videos. Good VRML viewing software, bundled with most new PCs, has sufficient power to support many engineering needs. In addition to publishing information science and engineering has an important tradition of peer and customer review. Reports, drawings and graphs are typically printed, distributed, reviewed, marked up, and returned to the author. Adding review comments to paper is easy. When, however, the information is in electronic form, this ease of review goes away. It's hard to write on videos. It's even harder to write comments on animated 3D models. These feedback limitations reduce the value of the information overall. Fortunately, the web can also be a useful tool for collecting peer and customer review information. When properly formed, web reports, movies, and 3D animations can be readily linked to review notes. This paper describes three multimedia feed-back systems that Sandia National Laboratories has developed to tap that potential. Each system allows people to make context-sensitive comments about specific web content and electronically ties the comments back to the web content being referenced. The fuel system ties comments to specific web pages, the second system ties the comments to specific frames of digital movies, and the third ties the comments to specific times and viewpoints within 3D animations. In addition to the technologies, this paper describes how they are being used to support intelligent machine systems design at Sandia.

  16. Structuring Free-text Microbiology Culture Reports For Secondary Use

    PubMed Central

    Yim, Wen-wai; Evans, Heather L.; Yetisgen, Meliha

    2015-01-01

    Microbiology lab culture reports are a frequently used diagnostic tool for clinical providers. However, their incorporation into clinical surveillance applications and evidence-based medicine can be severely hindered by the free-text nature of these reports. In this work, we (1) created a microbiology culture template to structure free-text microbiology reports, (2) generated an annotated microbiology report corpus, and (3) built a microbiology information extraction system. Specifically, we combined rule-based, hybrid, and statistical techniques to extract microbiology entities and fill templates for structuring data. System performances were favorable, with entity f1-score 0.889 and relation f1-score 0.795. We plan to incorporate these extractions as features for our ongoing ventilator-associated pneumonia surveillance project, though this tool can be used as an upstream process in other applications. Our newly created corpus includes 1442 unique gram stain and culture microbiology reports generated from a cohort of 715 patients at the University of Washington Medical Facilities. PMID:26306288

  2. Designing high-quality interactive multimedia learning modules.

    PubMed

    Huang, Camillan

    2005-01-01

    Modern research has broadened scientific knowledge and revealed the interdisciplinary nature of the sciences. For today's students, this advance translates to learning a more diverse range of concepts, usually in less time, and without supporting resources. Students can benefit from technology-enhanced learning supplements that unify concepts and are delivered on-demand over the Internet. Such supplements, like imaging informatics databases, serve as innovative references for biomedical information, but could improve their interaction interfaces to support learning. With information from these digital datasets, multimedia learning tools can be designed to transform learning into an active process where students can visualize relationships over time, interact with dynamic content, and immediately test their knowledge. This approach bridges knowledge gaps, fosters conceptual understanding, and builds problem-solving and critical thinking skills-all essential components to informatics training for science and medicine. Additional benefits include cost-free access and ease of dissemination over the Internet or CD-ROM. However, current methods for the design of multimedia learning modules are not standardized and lack strong instructional design. Pressure from administrators at the top and students from the bottom are pushing faculty to use modern technology to address the learning needs and expectations of contemporary students. Yet, faculty lack adequate support and training to adopt this new approach. So how can faculty learn to create educational multimedia materials for their students? This paper provides guidelines on best practices in educational multimedia design, derived from the Virtual Labs Project at Stanford University. The development of a multimedia module consists of five phases: (1) understand the learning problem and the users needs; (2) design the content to harness the enabling technologies; (3) build multimedia materials with web style standards and

    2010-01-01

    Digital multimedia such as images and videos are prevalent on today's internet and cause significant social impact, which can be evidenced by the proliferation of social networking sites with user generated contents. Due to the ease of generating and modifying images and videos, it is critical to establish trustworthiness for online multimedia information. In this paper, we propose novel approaches to perform multimedia forensics using compact side information to reconstruct the processing history of a document. We refer to this as FASHION, standing for Forensic hASH for informatION assurance. Based on the Radon transform and scale space theory, the proposed forensic hash is compact and can effectively estimate the parameters of geometric transforms and detect local tampering that an image may have undergone. Forensic hash is designed to answer a broader range of questions regarding the processing history of multimedia data than the simple binary decision from traditional robust image hashing, and also offers more efficient and accurate forensic analysis than multimedia forensic techniques that do not use any side information.

    PubMed

    Herrera, Anavella Gaitan

    2004-01-01

    Cosmetics are products of chemical or natural origin dedicated specifically for use in skin and mucosa. The constant development of the cosmetic industry has generated the necessity to carry out microbiological analysis on the raw materials used in the industrial production of cosmetics as well as the final products, with the purpose of obtaining products of good microbiological quality. Cosmetic products are recognized to be substrates for the survival and development of a large variety of microorganisms, since they possess some of the nutrients that facilitate growth such as: lipids, polysaccharides, alcohol, proteins, amino acids, glucosides, esteroids, peptides, and vitamins. Also, the conditions of readiness (oxygenation, pH, temperature, osmotic degree, superficial activity, perfume, and essential oils) present in the cosmetic products favor microbial multiplication. Routine analyses to determine the microbiological quality of a cosmetic product include the following: Count of mesophilic aerobic microorganisms. Most probable number (MPN) of total coliforms. Count of molds and yeasts. Absence/presence of Staphylococcus aureus probe. Absence/presence of Pseudomonas aeruginosa probe. PMID:15156038

    Multimedia is making an increasingly significant contribution to our informational society. The usefulness of this technology is already evident in education, business presentations, informational kiosks (e.g., in museums), training and the entertainment environment. Institutions, from grade schools to medical schools, are exploring the use of multifaceted electronic text books and teaching aids to enhance course materials. Through multimedia, teachers and students can take full advantage of the cognitive value of animation, audio, video and other types in a seamless application. The Software Technology Branch at NASA Johnson Space Center (NASA/JSC) is taking similar approaches to apply the state-of-the-art technology to space training, mission operations and other applications. This paper discusses the characteristics and development of multimedia applications at the NASA/JSC.

    Accessibility of multimedia information related to radiology in a timely manner is a key to success in practicing radiology in the future. In this paper we describe the concept of multimedia in the radiology environment and its implementation in our department at UCSF. This paper emphasizes the various types of databases related to radiology including HIS, RIS, PACS image database, digital voice dictation system, electronic mail and library information system. A method to interconnect these databases is through a comprehensive network architecture that also is described. As an application, we introduce the concept of a departmental image file server, for any of the 150 Macintosh users in the department to access this multimedia information.

    Clinical microbiologists should ensure, to the maximum level allowed by the scientific and technical development, the reliability of the results. This implies that, in addition to meeting the technical criteria to ensure their validity, they must be performed with a number of conditions that allows comparable results to be obtained, regardless of the laboratory that performs the test. In this sense, the use of recognized and accepted reference methodsis the most effective tool for these guarantees. The activities related to verification and validation of analytical methods has become very important, as there is continuous development, as well as updating techniques and increasingly complex analytical equipment, and an interest of professionals to ensure quality processes and results. The definitions of validation and verification are described, along with the different types of validation/verification, and the types of methods, and the level of validation necessary depending on the degree of standardization. The situations in which validation/verification is mandatory and/or recommended is discussed, including those particularly related to validation in Microbiology. It stresses the importance of promoting the use of reference strains as controls in Microbiology and the use of standard controls, as well as the importance of participation in External Quality Assessment programs to demonstrate technical competence. The emphasis is on how to calculate some of the parameters required for validation/verification, such as the accuracy and precision. The development of these concepts can be found in the microbiological process SEIMC number 48: «Validation and verification of microbiological methods» www.seimc.org/protocols/microbiology.

    This survey paper highlights some of the recent, influential work in multimedia information retrieval (MIR). MIR is a branch area of multimedia (MM). The young and fast-growing area has received strong industrial and academic support in the United States and around the world (see Section 7 for a list of major conferences and journals of the community). The term "information retrieval" may be misleading to those with different computer science or information technology backgrounds. As shown in our discussion later, it indeed includes topics from user interaction, data analytics, machine learning, feature extraction, information visualization, and more.

    The advent of multimedia pollution prevention programs has raised some interesting and challenging questions on the subject of facility operations. First and foremost is the goal of a multimedia pollution prevention program: how can industrial streams in an operating facility be treated to prevent pollutants from escaping in a particular effluent or waste streams without transferring the same pollutants to another medium? Once this is resolved, the next issue to be addressed is the fate of pollutants removed from effluent streams. EPA is moving toward discouraging destruction as an acceptable means of waste treatment. The strategies are presented for handling pollutants from one media without contaminating another.

    Farrett, Peter W.; Jardine, David A.

    1992-03-01

    This paper examines various issues related to the theory, design, and implementation of a system that supports creative activity for a multimedia environment. The system incorporates artificial intelligence notions to acquire concepts of the problem domain. This paper investigates this environment by considering a model that is a basis for a system, which supports a history of user interaction. A multimedia system that supports creative activity is problematic. It must function as a tool allowing users to experiment dynamically with their own creative reasoning process--a very nebulous task environment. It should also support the acquisition of domain knowledge so that empirical observation can be further evaluated. This paper aims to illustrate that via the reuse of domain-specific knowledge, closely related ideas can be quickly developed. This approach is useful in the following sense: Multimedia navigational systems hardcode referential links with respect to a web or network. Although users can access or control navigation in a nonlinear (static) manner, these referential links are 'frozen' and can not capture their creative actions, which are essential in tutoring or learning applications. This paper describes a multimedia assistant based on the notion of knowledge- links, which allows users to navigate through creative information in a nonlinear (dynamic) fashion. A selection of prototype code based on object-oriented techniques and logic programming partially demonstrates this.

  20. On the Accuracy Potential in Underwater/Multimedia Photogrammetry

    PubMed Central

    2015-01-01

    Underwater applications of photogrammetric measurement techniques usually need to deal with multimedia photogrammetry aspects, which are characterized by the necessity of handling optical rays that are refracted at interfaces between optical media with different refractive indices according to Snell’s Law. This so-called multimedia geometry has to be incorporated into geometric models in order to achieve correct measurement results. The paper shows a flexible yet strict geometric model for the handling of refraction effects on the optical path, which can be implemented as a module into photogrammetric standard tools such as spatial resection, spatial intersection, bundle adjustment or epipolar line computation. The module is especially well suited for applications, where an object in water is observed by cameras in air through one or more planar glass interfaces, as it allows for some simplifications here. In the second part of the paper, several aspects, which are relevant for an assessment of the accuracy potential in underwater/multimedia photogrammetry, are discussed. These aspects include network geometry and interface planarity issues as well as effects caused by refractive index variations and dispersion and diffusion under water. All these factors contribute to a rather significant degradation of the geometric accuracy potential in underwater/multimedia photogrammetry. In practical experiments, a degradation of the quality of results by a factor two could be determined under relatively favorable conditions. PMID:26213942

  2. An overview on scalable encryption for wireless multimedia access

    2003-08-01

    Wireless environments present many challenges for secure multimedia access, especial streaming media. The availability of varying network bandwidths and diverse receiver device processing powers and storage spaces demand scalable and flexible approaches that are capable of adapting to changing network conditions as well as device capabilities. To meet these requirements, scalable and fine granularity scalable (FGS) compression algorithms were proposed and widely adopted to provide scalable access of multimedia with interoperability between different services and flexible support to receivers with different device capabilities. Encryption is one of the most important security tools to protect content from unauthorized use. If a medium data stream is encrypted using non-scalable cryptography algorithms, decryption at arbitrary bit rate to provide scalable services can hardly be accomplished. If a medium compressed using scalable coding needs to be protected and non-scalable cryptography algorithms are used, the advantages of scalable coding may be lost. Therefore scalable encryption techniques are needed to provide scalability or to preserve the FGS adaptation capability (if the media stream is FGS coded) and enable intermediate processing of encrypted data without unnecessary decryption. In this paper, we will give an overview of scalable encryption schemes and present a fine grained scalable encryption algorithm. One desirable feature is its simplicity and flexibility in supporting scalable multimedia communication and multimedia content access control in wireless environments.

  3. Multimedia Environmental Distribution of Nanomaterials

    NASA Astrophysics Data System (ADS)

    Liu, Haoyang Haven

    Engineered nanomaterials (ENMs), which may be released to the environment due to human-related activities, can move across environmental phase boundaries and be found in most media. Given the rapid development and growing applications of nanotechnology, there is concern and thus the need to assess the potential environmental impact associated with ENMs. Accordingly, a modeling platform was developed to enable evaluation of the dynamic multimedia environmental distribution of ENMs (MendNano) and the range of potential exposure concentrations of ENMs. The MendNano was based on a dynamic multimedia compartmental modeling approach that was guided by detailed analysis of the agglomeration of ENMs, life-cycle analysis based estimates of their potential release to the environment, and incorporation of mechanistic sub-models of various intermedia transport processes. Model simulations for various environmental scenarios indicated that ENM accumulation in the sediment increased significantly with increased ENMs attachment to suspended solids in water. Atmospheric dry and wet depositions can be important pathways for ENMs input to the terrestrial environment in the absence of direct and distributed ENM release to soil. Increased ENM concentration in water due to atmospheric deposition (wet and dry) is expected as direct ENM release to water diminishes. However, for soluble ENMs dissolution can be the dominant pathway for suspended ENM removal from water even compared to advective transport. For example, simulations for Los Angeles showed that dry deposition, rain scavenging, and wind dilution can remove 90% of ENMs from the atmospheric airshed in ~100-230 days, ~2-6 hrs, and ~0.5-2 days, respectively. For the evaluated ENMs (metal, metal oxides, carbon nanotubes (CNT), nanoclays), mass accumulation in the multimedia environment was mostly in the soil and sediment. Additionally, simulation results for TiO2 in Los Angeles demonstrates that the ENM concentrations in air and

    In recent years, mobile devices are quickly reaching almost every corner of our daily life in a variety of forms: personal media players, smart phones, netbooks, and tablets. Besides the more powerful, smaller, and more versatile hardware, another driving force is the vast number of software applications ("apps") on those mobile devices. A number of mobile apps employ intelligent multimedia understanding (MU) technologies. This paper gives an overview of such apps. The focus is not on the underlying MU techniques, which are already covered by a huge amount of literature. Instead, it attempts to shed some light on the junction of mobile apps and MU. For this purpose, it addresses a number of important aspects: unique requirements and characteristics of MU-related apps, values brought in by MU, typical MU technologies, various system architectures, available development tools, and related standards.

    Personal Telepresence is an interactive multimedia tool that allows individuals or groups to, affordably, meet with remotely located individuals or groups--from their desktop--as if they were all in the same location. A Personal Telepresence workstation would include telephony, computer, desktop videoconferencing, groupware, and graphics capability on a single platform. The user interface presented will allow natural, face-to-face interaction between all those involved in `virtual' meeting, classroom, office or manufacturing problem solving sessions. Files could be opened and placed on a virtual `conference table' where changes could be made interactively by any or all the `meeting' participants. `Copies' of the files can be made, `stapled' together, and given to each of the attendees. The desktop would include a `whiteboard' for brainstorming sessions and a `projector screen' to display movies, video mail, and/or the results of a simulation program. This paper discusses desktop collaboration needs and the Personal Telepresence project at LLNL.

The model of a server running a monolithic application and supporting clients at the desktop is giving way to a different model that blurs the line between client and server. We are on the verge of plunging into the next generation of computing technology--distributed object-oriented computing. This is not only a change in requirements but a change in opportunities, and requires a new way of thinking for Information System (IS) developers. The information system demands caused by global competition are requiring even more access to decision making tools. Simply, object-oriented technology has been developed to supersede the current design process of information systems which is not capable of handling next generation multimedia.

    The most recent approach to the development of novel antimicrobial and antifungal agents is based on the application of synthetic and natural zeolites, because zeolites are known to be the carrier and slow releaser of the heavy metals with olygodynamic properties. The microbiological activity of the ion-exchanged zeolites is attributed to the ionic state of the metal sreleased from the zeolites by ion re-exchange. In the present work we used low cost natural clinoptilolite (Cli) as a substrate for copper and silver in different states. The state of oxidation of the exchanged metal in zeolite with supported Cu and Ag species (in the form of cations, small clusters, sub-coloidal particles, large particles) in order to fit them to fulfill the following criteria: to demonstrate their high protective abilities against fungi and long-term stability. The study of structure of samples with XRD, UV-visible spectroscopy, FTIR, their stability with temperature and during storage was carried out for obtaining the correct correlation with microbiological activity.

    2016-07-01

    Most sinus infections are viral and only a small percentage develop bacterial infection. Rhino-, influenza, and para-influenza viruses are the most frequent viral causes of sinusitis. The most common bacterial isolates from children and adult patients with community-acquired acute bacterial sinusitis are Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis, and Streptococcus pyogenes. Staphylococcus aureus and anaerobic organisms (Prevotella and Porphyromonas, Fusobacterium, and Peptostreptococcus spp.) are the commonest isolates in chronic rhinosinusitis (CRS). Aerobic and anaerobic beta lactamase-producing bacteria (BLPB) were recovered from over a third of these patients. Methicillin-resistant S. aureus (MRSA) accounted for over 60 % of S. aureus isolates. Pseudomonas aeruginosa and other aerobic and facultative Gram-negative rods are frequently recovered in nosocomial sinusitis, the immunocompromised host, individuals with human immunodeficiency virus infection, and in cystic fibrosis. The CRS infection evolves the formation of a biofilm that might play a significant role in the pathogenesis and persistence of CRS. The microbiology of sinusitis is influenced by previous antimicrobial therapy, vaccinations, and the presence of normal flora capable of interfering with the growth of pathogens. Recognition of the unique microbiology of CRS and their antimicrobial susceptibility is of great importance when selecting antimicrobial therapy. PMID:27086363

    Collaborative e-learning is increasingly appealing as a pedagogical approach that can positively affect student learning. We propose a didactical model that integrates multimedia with collaborative tools and peer assessment to foster collaborative e-learning. In this paper, we explain it and present the results of its application to the "International Seminars on Materials Science" online course. The proposed didactical model consists of five educational activities. In the first three, students review the multimedia resources proposed by the teacher in collaboration with their classmates. Then, in the last two activities, they create their own multimedia resources and assess those created by their classmates. These activities foster communication and collaboration among students and their ability to use and create multimedia resources. Our purpose is to encourage the creativity, motivation, and dynamism of the learning process for both teachers and students.

    Multimedia modelers from the United States Environmental Protection Agency (EPA) and the United States Department of Energy (DOE) collaborated to conduct a comprehensive and quantitative benchmarking analysis of three multimedia models. The three models-RESRAD (DOE), MMSOILS (EPA), and MEPAS (DOE)-represent analytically based tools that are used by the respective agencies for performing human exposure and health risk assessments. The study is performed by individuals who participate directly in the ongoing design, development, and application of the models. A list of physical/chemical/biological processes related to multimedia-based exposure and risk assessment is first presented as a basis for comparing the overall capabilities of RESRAD, MMSOILS, and MEPAS. Model design, formulation, and function are then examined by applying the models to a series of hypothetical problems. Major components of the models (e.g., atmospheric, surface water, groundwater) are evaluated separately and then studied as part of an integrated system for the assessment of a multimedia release scenario to determine effects due to linking components of the models. Seven modeling scenarios are used in the conduct of this benchmarking study: (1) direct biosphere exposure, (2) direct release to the air, (3) direct release to the vadose zone, (4) direct release to the saturated zone, (5) direct release to surface water, (6) surface water hydrology, and (7) multimedia release. Study results show that the models differ with respect to (1) environmental processes included (i.e., model features) and (2) the mathematical formulation and assumptions related to the implementation of solutions (i.e., parameterization).

    Since the initial observations of oral bacteria within dental plaque by van Leeuwenhoek using his primitive microscopes in 1680, an event that is generally recognized as the advent of oral microbiological investigation, oral microbiology has gone through phases of “reductionism” and “holism”. From the small beginnings of the Miller and Black period, in which microbiologists followed Koch's postulates, took the reductionist approach to try to study the complex oral microbial community by analyzing individual species; to the modern era when oral researchers embrace “holism” or “system thinking”, adopt new concepts such as interspecies interaction, microbial community, biofilms, poly-microbial diseases, oral microbiological knowledge has burgeoned and our ability to identify the resident organisms in dental plaque and decipher the interactions between key components has rapidly increased, such knowledge has greatly changed our view of the oral microbial flora, provided invaluable insight into the etiology of dental and periodontal diseases, opened the door to new approaches and techniques for developing new therapeutic and preventive tools for combating oral poly-microbial diseases.

    The effects of microbial fouling on treatment bed (TB) performance are being studied. Fouling of activated carbon (AC) and ion exchange resins (IEX) by live and devitalized bacteria can cause decreased capacity for selected sorbates with AC and IEX TB. More data are needed on organic species removal in the trace region of solute sorption isotherms. TB colonization was prevented by nonclassical chemical disinfectant compositions (quaternary ammonium resins) applied in suitable configurations. Recently, the protection of carbon beds via direct disinfectant impregnation has shown promise. Effects (of impregnation) upon bed sorption/removal characteristics are to be studied with representative contaminants. The potential need to remove solutes added or produced during water disinfection and/or TB microbiological control must be investigated.

    For decades, Aggregatibacter actinomycetemcomitans has been considered the most likely etiologic agent in aggressive periodontitis. Implementation of DNA-based microbiologic methodologies has considerably improved our understanding of the composition of subgingival biofilms, and advanced open-ended molecular techniques even allow for genome mapping of the whole bacterial spectrum in a sample and characterization of both the cultivable and not-yet-cultivable microbiota associated with periodontal health and disease. Currently, A. actinomycetemcomitans is regarded as a minor component of the resident oral microbiota and as an opportunistic pathogen in some individuals. Its specific JP2 clone, however, shows properties of a true exogenous pathogen and has an important role in the development of aggressive periodontitis in certain populations. Still, limited data exist on the impact of other microbes specifically in aggressive periodontitis. Despite a wide heterogeneity of bacteria, especially in subgingival samples collected from patients, bacteria of the red complex in particular, and those of the orange complex, are considered as potential pathogens in generalized aggressive periodontitis. These types of bacterial findings closely resemble those found for chronic periodontitis, representing a mixed polymicrobial infection without a clear association with any specific microorganism. In aggressive periodontitis, the role of novel and not-yet-cultivable bacteria has not yet been elucidated. There are geographic and ethnic differences in the carriage of periodontitis-associated microorganisms, and they need to be taken into account when comparing study reports on periodontal microbiology in different study populations. In the present review, we provide an overview on the colonization of potential periodontal pathogens in childhood and adolescence, and on specific microorganisms that have been suspected for their role in the initiation and progression of aggressive

    1999-01-01

    Multimedia, as an application, has at its very core the field of signal processing technology. Although, multimedia has leveraged on numerous disciplines, signal processing is the most relevant. Some of the basic concepts, such as spectral analyses, sampling theory and the theory of partial differential equations have become the fundamental building blocks for numerous applications and subsequently have been reinvested in such diverse areas as transform coding, display technology and neural networks. The latter, most recently, leads to a fast implementation of vector quantization. It is evident, that the diverse signal processing algorithms, concepts and applications are interconnected and in numerous instances appear in various reincarnated forms. For example, sub-band coding existed for many years before wavelets became fashionable. In this paper, an attempt will be made to provide a historical overview of signal processing through the present, followed by a highly personal speculation for the future.

    Methods of computer technology (intelligent technology, IT), such as multimedia and virtual reality, are utilized more and more in all medical fields including child neurology. Advances in the digitalization of individual medical data and multi-media technology have enabled patients to be able to obtain their own medical data by small media and to receive medical treatment at any hospitals even if they are located in distance place. Changes from a doctor oriented to patients oriented medicine is anticipated. It is necessary to store medical data from birth to adulthood and to accumulate epidemiological data of rare diseases such as metabolic diseases or degenerative diseases especially in child neurology, which highly require tele medicine and telecare at home. Moreover, IT may improve in the QOL of patients with neurological diseases and of their families. Cooperation of medicine and engineering is therefore necessary. Results of our experiments on telemedicine, telecare and virtual reality are described. PMID:11808201

    Phillips, J.B.; Hindawi, M.A.

    1996-02-01

    One of the major driving forces in the decision of a facility operator to implement a multimedia approach to examining pollution is the economics of the situation. A multimedia approach has gained favor with many facility operators because it has been shown to be more cost-effective than dealing with a number of phases, or media, separately. To a great extent, this is due to elimination of inefficiencies involved with cross-media transfer of pollutants. Even more basic to the problem of industrial pollution is the generation of waste. All industrial processes yield some percentage of waste products, but frequently during the design phase the costs associated with producing wastes are underestimated. As part of this series on multimedia issues, the costs related to manufacturing waste products are examined in detail. An obvious inefficiency associated with waste generation is the loss of material that potentially could be converted to salable products. The value of commodity raw materials frequently is ignored when considering the total costs of pollution generation at an industrial facility. Although the economics of pollution generation are affected by a number of factors, including regulatory costs, disposal costs and impacts on health and safety, this article focuses on the economics of lost production in industrial facilities.

    Zhang, Fulei

    The use of multimedia technologies in education has enabled teachers to simulate final outcomes and assist s-tudents in applying knowledge learned from textbooks, thereby compensating for the deficiency of traditional teach- ing methods. It is important to examine how effective these technologies are in practical use. This study developed online learning-teaching resource platforms using Flash multimedia, providing interactive and integrated features in an easy-to-use user interface, in order to discuss Computer-Aided Drawing (CAD). The study utilized a teaching experiment with a non-equivalent pretest-posttest control group design to test and discuss students' professional cognition, operating skill cognition, and level of learning satisfaction during the learning process. No significant differences emerged between the groups in regards to professional cognition or operation skills cognition. However, a significant difference in learning satisfaction was noted, indicating that the coursework with multimedia Flash produced greater satisfaction than with traditional learning methods. Results are explained in detail and recommendations for further research provided.

    As humans continue to explore deep into space, microorganisms will travel with them. The primary means to mitigate the risk of infectious disease are a combination of prudent spacecraft design and rigorous operational controls. The effectiveness of these methods are evaluated by microbiological monitoring of spacecraft, food, water, and the crew that is performed preflight, in-flight, and post-flight. Current NASA requirements associated with microbiological monitoring are based on culture-based methodology where microorganisms are grown on a semi-solid growth medium and enumerated. Subsequent identification of the organisms requires specialized labor and large equipment, which historically has been performed on Earth. Requirements that rely strictly on culture-based units limit the use of non-culture based monitoring technology. Specifically, the culture-based "measurement criteria" are Colony Forming Units (CFU, representing the growth of one microorganism at a single location on the agar medium) per a given volume, area, or sample size. As the CFU unit by definition is culture-based, these requirements limit alternative technologies for spaceflight applications. As spaceflight missions such as those to Mars extend further into space, culture-based technology will become difficult to implement due to the (a) limited shelf life of the culture media, (b) mass/volume necessary to carry these consumables, and (c) problems associated with the production of biohazardous material in the habitable volume of the spacecraft. In addition, an extensive amount of new knowledge has been obtained during the Space Shuttle, NASA-Mir, and International Space Station Programs, which gave direction for new or modified microbial control requirements for vehicle design and mission operations. The goal of this task is to develop and recommend a new set of requirements for vehicle design and mission operations, including microbiological monitoring, based upon "lessons learned" and new

    SciTech Connect

    Kieft, Thomas L.; Brockman, Fred J.

    2001-01-17

    The vadose zone is defined as the portion of the terrestrial subsurface that extends from the land surface downward to the water table. As such, it comprises the surface soil (the rooting zone), the underlying subsoil, and the capillary fringe that directly overlies the water table. The unsaturated zone between the rooting zone and the capillary fringe is termed the "intermediate zone" (Chapelle, 1993). The vadose zone has also been defined as the unsaturated zone, since the sediment pores and/or rock fractures are generally not completely water filled, but instead contain both water and air. The latter characteristic results in the term "zone of aeration" to describe the vadose zone. The terms "vadose zone," "unsaturated zone", and "zone of aeration" are nearly synonymous, except that the vadose zone may contain regions of perched water that are actually saturated. The term "subsoil" has also been used for studies of shallow areas of the subsurface immediately below the rooting zone. This review focuses almost exclusively on the unsaturated region beneath the soil layer since there is already an extensive body of literature on surface soil microbial communities and process, e.g., Paul and Clark (1989), Metting (1993), Richter and Markowitz, (1995), and Sylvia et al. (1998); whereas the deeper strata of the unsaturated zone have only recently come under scrutiny for their microbiological properties.

    Searching for life in astromaterials to be delivered from the future missions to extraterrestrial bodies is undoubtedly related to studies of the properties and signatures of living microbial cells and microfossils on Earth. The Antarctic glacier and Earth permafrost habitats, where living microbial cells preserved viability for millennia years due to entering the anabiotic state, are often regarded as terrestrial analogs of Martian polar subsurface layers. For the future findings of viable microorganisms in samples from extraterrestrial objects, it is important to use a combined methodology that includes classical microbiological methods, plating onto nutrient media, direct epifluorescence and electron microscopy examinations, detection of the elemental composition of cells, PCR and FISH methods. Of great importance is to ensure authenticity of microorganisms (if any in studied samples) and to standardize the protocols used to minimize a risk of external contamination. Although the convincing evidence of extraterrestrial microbial life will may come from the discovery of living cells in astromaterials, biomorphs and microfossils must also be regarded as a target in search of life evidence bearing in mind a scenario that living microorganisms had not been preserved and underwent mineralization. Regarding the vital importance of distinguishing between biogenic and abiogenic signatures and between living and fossil microorganisms in analyzed samples, it is worthwhile to use previously developed approaches based on electron microscopy examinations and analysis of elemental composition of biomorphs in situ.

  5. Superresolution microscopy for microbiology

    Coltharp, Carla; Xiao, Jie

    2014-01-01

    Summary This review provides a practical introduction to superresolution microscopy from the perspective of microbiological research. Because of the small sizes of bacterial cells, superresolution methods are particularly powerful and suitable for revealing details of cellular structures that are not resolvable under conventional fluorescence light microscopy. Here we describe the methodological concepts behind three major categories of super-resolution light microscopy: photoactivated localization microscopy (PALM) and stochastic optical reconstruction microscopy (STORM), structured illumination microscopy (SIM) and stimulated emission-depletion (STED) microscopy. We then present recent applications of each of these techniques to microbial systems, which have revealed novel conformations of cellular structures and described new properties of in vivo protein function and interactions. Finally, we discuss the unique issues related to implementing each of these superresolution techniques with bacterial specimens and suggest avenues for future development. The goal of this review is to provide the necessary technical background for interested microbiologists to choose the appropriate super-resolution method for their biological systems, and to introduce the practical considerations required for designing and analysing superresolution imaging experiments.

  4. Colloquium and Report on Systems Microbiology: Beyond Microbial Genomics

    Merry R. Buckley

    2004-12-13

    The American Academy of Microbiology convened a colloquium June 4-6, 2004 to confer about the scientific promise of systems microbiology. Participants discussed the power of applying a systems approach to the study of biology and to microbiology in particular, specifics about current research efforts, technical bottlenecks, requirements for data acquisition and maintenance, educational needs, and communication issues surrounding the field. A number of recommendations were made for removing barriers to progress in systems microbiology and for improving opportunities in education and collaboration. Systems biology, as a concept, is not new, but the recent explosion of genomic sequences and related data has revived interest in the field. Systems microbiology, a subset of systems biology, represents a different approach to investigating biological systems. It attempts to examine the emergent properties of microorganisms that arise from the interplay of genes, proteins, other macromolecules, small molecules, organelles, and the environment. It is these interactions, often nonlinear, that lead to the emergent properties of biological systems that are generally not tractable by traditional approaches. As a complement to the long-standing trend toward reductionism, systems microbiology seeks to treat the organism or community as a whole, integrating fundamental biological knowledge with genomics, metabolomics, and other data to create an integrated picture of how a microbial cell or community operates. Systems microbiology promises not only to shed light on the activities of microbes, but will also provide biology the tools and approaches necessary for achieving a better understanding of life and ecosystems. Microorganisms are ideal candidates for systems biology research because they are relatively easy to manipulate and because they play critical roles in health, environment, agriculture, and energy production.

  8. Children in Japan and multimedia.

    Shimauchi, Y

    1999-01-01

    Many parents in Japan today are very concerned and have daily problems with their children over the following kind of issues concerning video games, multimedia, and similar devices. 1) Is children's enthusiasm for video games actually harming their growth (physically or mentally)? 2) Is there any way that video games can help children in the future? For example, will playing these games help children learn to use computers or develop their power of thought? 3) Will excessive enthusiasm for TV games undermine our basic lifestyle? Is the time they spend studying at home or playing outside actually decreasing? 4) Will the methods of communication brought about by computers, pagers, and cellular phones weaken human relations among children? 5) Will being immersed in a virtual world created by computers result in a diminished sense of reality? The causes of this uneasiness may be traced to parents' own anxieties and concerns about the exceedingly rapid growth of the "information society" of today, together with the fact that their children are directly caught up in the deluge of this information and multimedia society. The development of media has coincided with the growth of today's adults, but children are immersed in a media-filled environment from the day they are born. In Japan, there are now children who can play video games before even learning to write. No one can predict what kind of adults these children will grow to be in the future, and it is fair to say that the most parents and children in Japan are being tossed about on the waves of this information explosion. At this international symposium, we hope to hear the many views that are held around the world concerning children and multimedia. PMID:10770069

    Analysts who work with collections of multimedia to perform information foraging understand how difficult it is to connect information across diverse sets of mixed media. The wealth of information from blogs, social media, and news sites often can provide actionable intelligence; however, many of the tools used on these sources of content are not capable of multimedia analysis because they only analyze a single media type. As such, analysts are taxed to keep a mental model of the relationships among each of the media types when generating the broader content picture. To address this need, we have developed Canopy, a novel visual analytic tool for analyzing multimedia. Canopy provides insight into the multimedia data relationships by exploiting the linkages found in text, images, and video co-occurring in the same document and across the collection. Canopy connects derived and explicit linkages and relationships through multiple connected visualizations to aid analysts in quickly summarizing, searching, and browsing collected information to explore relationships and align content. In this paper, we will discuss the features and capabilities of the Canopy system and walk through a scenario illustrating how this system might be used in an operational environment.

    Phillips, J.B.; Hindawi, M.A.

    1997-01-01

    A multimedia approach to pollution prevention that focuses on minimizing or eliminating production of pollutants is one of the most advantageous strategies to adopt in preparing an overall facility environmental plan. If processes are optimized to preclude or minimize the manufacture of streams containing pollutants, or to reduce the levels of pollutants in waste streams, then the task of multimedia pollution prevention becomes more manageable simply as a result of a smaller problem needing to be addressed. An orderly and systematic approach to waste minimization can result in a comprehensive strategy to reduce the production of waste streams and simultaneously improve the profitability of a process or industrial operation. There are a number of miscellaneous strategies for a waste minimization that attack the problem via process chemistry or engineering. Examples include installation of low-NO{sub x} burners, selection of valves that minimize fugitive emissions, high-level switches on storage tanks, the use of in-plant stills for recycling and reusing solvents and using water-based products instead of hydrocarbon-based products wherever possible. Other waste minimization countermeasures can focus on O and M issues.

    Development towards high-bandwidth wireless devices that are capable of processing complex, streaming multimedia is enabling a new breed of network-based media services. Coping with the diversity of network and device capabilities requires services to be flexible and able to adapt to the needs and limitations of the environment at hand. Before efficient deployment, multi-platform services require additional issues to be considered, e.g. content handling, digital rights management, adaptability of content, user profiling, provisioning, and the available access methods. The key issue is how the content and the service is being modelled and stored for inauguration. We propose a new service content model based on persistent media objects able to store and manage XHTML-based multimedia services. In our approach, media, content summaries, and other meta-information are stored within media objects that can be queried from the object database. The content of the media objects can also specify queries to the database and links to other media objects. The final presentation is created dynamically according to the service request and user profiles. Our approach allows for dynamic updating of the service database together with user group management, and provides a method for notifying the registered users by different smart messaging methods, e.g. via e-mail or a SMS message. The model is demonstrated with an 'ice-hockey service' running in our platform called Princess. The service also utilizes SMIL and key frame techniques for the video representation.

  8. [Post-mortem microbiology analysis].

    PubMed

    Fernández-Rodríguez, Amparo; Alberola, Juan; Cohen, Marta Cecilia

    2013-12-01

    Post-mortem microbiology is useful in both clinical and forensic autopsies, and allows a suspected infection to be confirmed. Indeed, it is routinely applied to donor studies in the clinical setting, as well as in sudden and unexpected death in the forensic field. Implementation of specific sampling techniques in autopsy can minimize the possibility of contamination, making interpretation of the results easier. Specific interpretation criteria for post-mortem cultures, the use of molecular diagnosis, and its fusion with molecular biology and histopathology have led to post-mortem microbiology playing a major role in autopsy. Multidisciplinary work involving microbiologists, pathologists, and forensic physicians will help to improve the achievements of post-mortem microbiology, prevent infectious diseases, and contribute to a healthier population.

  9. Multimedia psychodynamic psychotherapy: a preliminary report.

    PubMed

    Nesci, Domenico Arturo

    2009-05-01

    Mourning the death of a beloved person is one of life's most stressful events. This psychotherapy case study describes a form of psychodynamic psychotherapy that the author developed in working with a patient who suffered from complicated grief after the death of her father from lung cancer. During sessions, the therapist worked with the patient to collect pictures and organize a "strip of life" of her father's most meaningful moments. The patient then wrote a short text associated with each picture. Finally, she chose music to be added to this "slide show" or "psychodynamic montage" as its soundtrack. The resulting multimedia presentation was finally posted on the Internet on a website to which only the patient and her relatives and friends had access via a password. This therapeutic strategy was effective in helping this patient resolve her symptoms of complicated grief. The author suggests that this new approach to psychodynamic psychotherapy may be a cost-effective and well-received tool for use in institutions such as hospices and general hospitals. PMID:19461394

  13. Application-oriented architecture for multimedia teleservices

    NASA Astrophysics Data System (ADS)

    Vanrijssen, Erwin; Widya, Ing; Michiels, Eddie

    This paper looks into communications capabilities that are required by distributed multimedia applications to achieve relation preserving information exchange. These capabilities are derived by analyzing the notion of 'information exchange' and are embodied in communications functionalities. To emphasize the importance of the users' view, a top-down approach is applied. The revised Open Systems Interconnection (OSI) Application Layer Structure (OSI-ALS) is used to model the communications functionalities and to develop an architecture for composition of multimedia teleservices with these functionalities. This work may therefore be considered an exercise to evaluate the suitability of OSI-ALS for composition of multimedia teleservices.

    PubMed

    Aznar, Javier; Nogueira, José Miguel

    2010-10-01

    Many professionals from distinct disciplines work in health centers and consequently these workplaces should be considered as service companies, involving human, material and financial resources aimed at providing a service required by society. Hospitals are one of the most complex types of company, in which diverse goods and services are produced and consumed. Like the hospital as a whole, the various units and departments in which the hospital is divided, including the microbiology department, are sufficiently different to be called distinct, but related, branches of the same company, given that none can perform their function without the others. Viewing a hospital service as a branch of a large company (the hospital as a whole) allows its production, the resources used in this production, and its clients to be identified more clearly. The healthcare model based on clinical management units aims to constitute a new organizational model for public health systems in which health strategies are performed that allow innovation and decentralization of the healthcare network. Clinical management provides the framework for attending to the population's healthcare needs through a person-centered approach and involves all the professionals in any of the settings in which healthcare is provided. Among the aims of this model is to guarantee continuity of care, facilitate comprehensive health promotion and deliver daily healthcare effectively. The main instruments of clinical management are structured knowledge of the population's health needs, the use of the best scientific knowledge available, and a comprehensive and participatory practical model, together with assessment tools. Three possible clinical management models are proposed for the work of specialists in microbiology and parasitology: a) a microbiology clinical management unit; b) a biological diagnosis clinical management unit, and c) a multidisciplinary clinical management unit with cross-competencies with

  18. 3D Integration for Wireless Multimedia

    NASA Astrophysics Data System (ADS)

    Kimmich, Georg

    The convergence of mobile phone, internet, mapping, gaming and office automation tools with high quality video and still imaging capture capability is becoming a strong market trend for portable devices. High-density video encode and decode, 3D graphics for gaming, increased application-software complexity and ultra-high-bandwidth 4G modem technologies are driving the CPU performance and memory bandwidth requirements close to the PC segment. These portable multimedia devices are battery operated, which requires the deployment of new low-power-optimized silicon process technologies and ultra-low-power design techniques at system, architecture and device level. Mobile devices also need to comply with stringent silicon-area and package-volume constraints. As for all consumer devices, low production cost and fast time-to-volume production is key for success. This chapter shows how 3D architectures can bring a possible breakthrough to meet the conflicting power, performance and area constraints. Multiple 3D die-stacking partitioning strategies are described and analyzed on their potential to improve the overall system power, performance and cost for specific application scenarios. Requirements and maturity of the basic process-technology bricks including through-silicon via (TSV) and die-to-die attachment techniques are reviewed. Finally, we highlight new challenges which will arise with 3D stacking and an outlook on how they may be addressed: Higher power density will require thermal design considerations, new EDA tools will need to be developed to cope with the integration of heterogeneous technologies and to guarantee signal and power integrity across the die stack. The silicon/wafer test strategies have to be adapted to handle high-density IO arrays, ultra-thin wafers and provide built-in self-test of attached memories. New standards and business models have to be developed to allow cost-efficient assembly and testing of devices from different silicon and technology

    In a short period of time, the multimedia sector has quickly progressed trying to overcome the exigencies of the customers in terms of transfer speeds, storage memory, image quality, and functionalities. In order to cope with this stringent situation, different hardware devices have been developed as possible choices. Despite of the fact that not every device is apt for implementing the high computational demands associated to multimedia applications; reconfigurable architectures appear as ideal candidates to achieve these necessities. As a direct consequence, worldwide universities and industries have incremented their research activity into this area, generating an important know-how base. In order to sort all the information generated about this issue, this paper reviews the most recent reconfigurable architectures for multimedia applications. As a result, this paper establishes the benefits and drawbacks of the different dynamically reconfigurable architectures for multimedia applications according to their system-level design.

  20. Multimedia content management in MPEG-21 framework

    NASA Astrophysics Data System (ADS)

    Smith, John R.

    2002-07-01

    MPEG-21 is an emerging standard from MPEG that specifies a framework for transactions of multimedia content. MPEG-21 defines the fundamental concept known as a digital item, which is the unit of transaction in the multimedia framework. A digital item can be used to package content for such as a digital photograph, a video clip or movie, a musical recording with graphics and liner notes, a photo album, and so on. The packaging of the media resources, corresponding identifiers, and associated metadata is provided in the declaration of the digital item. The digital item declaration allows for more effective transaction, distribution, and management of multimedia content and corresponding metadata, rights expressions, variations of media resources. In this paper, we describe various challenges for multimedia content management in the MPEG-21 framework.

  6. Frontiers in Microbiology: Envisioning a Curriculum Unit for High School Biology

    SciTech Connect

    Mark Bloom

    2004-06-18

    Microbiology is undergoing a quiet revolution. Techniques such as polymerase chain reaction, high throughput DNA sequencing, whole genome shotgun sequencing, DNA microarrays, and bioinformatics analyses are greatly aiding our understanding of the estimated one billion species of microbes that inhabit the Earth. Unfortunately, the rapid pace of research in microbiology stands in contrast to the much slower pace of change in educational reform. Biological Sciences Curriculum Study (BSCS) hosted a two-day planning meeting to discuss whether or not a new curriculum unit on microbiology is desirable for the high school audience. Attending the meeting were microbiologists, high school biology teachers, and science educators. The consensus of the participants was that an inquiry-based unit dealing with advances in microbiology should be developed for a high school biology audience. Participants established content priorities for the unit, discussed the unit's conceptual flow, brainstormed potential student activities, and discussed the role of educational technology for the unit. As a result of the planning meeting discussions, BSCS staff sought additional funding to develop, disseminate, and evaluate the Frontiers in Microbiology curriculum unit. This unit was intended to be developed as a replacement unit suitable for an introductory biology course. The unit would feature inquiry-based student activities and provide approximately four weeks of instruction. As appropriate, activities would make use of multimedia. The development and production processes would require about two years for completion. Unfortunately, BSCS staff was not able to attract sufficient funding to develop the proposed curriculum unit. Since there were some unexpended funds left over from the planning meeting, BSCS requested and received permission from DOE to use the balance of the funds to prepare background materials about advances in microbiology that would be useful to teachers. These materials

  8. Microbiological Quantitative Risk Assessment

    NASA Astrophysics Data System (ADS)

    Dominguez, Silvia; Schaffner, Donald W.

    The meat and poultry industry faces ongoing challenges due to the natural association of pathogens of concern (e.g., Salmonella, Campylobacter jejuni, Escherichia coli O157:H7) with a variety of domesticated food animals. In addition, pathogens such as Listeria monocytogenes pose a significant cross-contamination risk during further meat and poultry processing, distribution, and storage. Furthermore, the meat and poultry industries are constantly changing with the addition of new products, use of new raw materials, and targeting of new consumer populations, each of which may give rise to potential new risks. National and international regulations are increasingly using a “risk-based” approach to food safety (where the regulatory focus is driven by the magnitude of the risk), so risk assessment is becoming a valuable tool to systematically organize and evaluate the potential public health risk posed by food processing operations.

  9. Disk scheduling for multimedia data streams

    NASA Astrophysics Data System (ADS)

    Daigle, Steve J.; Strosnider, Jay K.

    1994-04-01

    This paper presents a framework for reasoning about the timing correctness of multimedia data streams supported on a shared, serially-reusable server. A real-time scheduling approach is used to guarantee the timing requirements for multimedia applications such as video-on- demand and multimedia presentations. This framework incorporates the use of scheduling models, which are defined as abstractions that can be used to reason about timing correctness on physical resources. The scheduling models in this paper can be applied to multimedia systems which use periodic tasks to retrieve data from a disk. With their use, the multimedia system designer can reason a priori about the throughput, capacity, and schedulability of a system. The models enable the real-time system architect to quickly explore the system design space, to establish and maintain a firm performance baseline, to optimize system configuration parameters, and to explore the impact of new technologies. As an example of the application of this framework a new disk policy called T-scan is developed here. T-scan is applied to a multimedia task set and the analytical results are presented. Additionally, the performance of various disk policies are compared using the framework.

    SciTech Connect

    Francis, A.J.

    1992-12-31

    The ability of microorganisms which are ubiquitous throughout nature to bring about information of organic and inorganic compounds in radioactive wastes has been recognized. Unlike organic contaminants, metals cannot be destroyed, but must be either removed or converted to a stable form. Radionuclides and toxic metals in wastes may be present initially in soluble form or, after disposal may be converted to a soluble form by chemical or microbiological processes. The key microbiological reactions include (i) oxidation/reduction; (ii) change in pH and Eh which affects the valence state and solubility of the metal; (iii) production of sequestering agents; and (iv) bioaccumulation. All of these processes can mobilize or stabilize metals in the environment.

    Heidelbaugh, N. D.; Mcqueen, J. L.; Rowley, D. B.; Powers , E. M.; Bourland, C. T.

    1973-01-01

    Review of some of the unique food microbiology problems and problem-generating circumstances the Skylab manned space flight program involves. The situations these problems arise from include: extended storage times, variations in storage temperatures, no opportunity to resupply or change foods after launch of the Skylab Workshop, first use of frozen foods in space, first use of a food-warming device in weightlessness, relatively small size of production lots requiring statistically valid sampling plans, and use of food as an accurately controlled part in a set of sophisticated life science experiments. Consideration of all of these situations produced the need for definite microbiological tests and test limits. These tests are described along with the rationale for their selection. Reported test results show good compliance with the test limits.

  19. Microbiological Spoilage of Cereal Products

    NASA Astrophysics Data System (ADS)

    Cook, Frederick K.; Johnson, Billie L.

    A wide range of cereal products, including bakery items, refrigerated dough, fresh pasta products, dried cereal products, snack foods, and bakery mixes, are manufactured for food consumption. These products are subject to physical, chemical, and microbiological spoilage that affects the taste, aroma, leavening, appearance, and overall quality of the end consumer product. Microorganisms are ubiquitous in nature and have the potential for causing food spoilage and foodborne disease. However, compared to other categories of food products, bakery products rarely cause food poisoning. The heat that is applied during baking or frying usually eliminates pathogenic and spoilage microorganisms, and low moisture contributes to product stability. Nevertheless, microbiological spoilage of these products occurs, resulting in substantial economic losses.

  20. Clinical microbiology of coryneform bacteria.

    PubMed Central

    Funke, G; von Graevenitz, A; Clarridge, J E; Bernard, K A

    1997-01-01

    Coryneform bacteria are aerobically growing, asporogenous, non-partially-acid-fast, gram-positive rods of irregular morphology. Within the last few years, there has been a massive increase in the number of publications related to all aspects of their clinical microbiology. Clinical microbiologists are often confronted with making identifications within this heterogeneous group as well as with considerations of the clinical significance of such isolates. This review provides comprehensive information on the identification of coryneform bacteria and outlines recent changes in taxonomy. The following genera are covered: Corynebacterium, Turicella, Arthrobacter, Brevibacterium, Dermabacter. Propionibacterium, Rothia, Exiguobacterium, Oerskovia, Cellulomonas, Sanguibacter, Microbacterium, Aureobacterium, "Corynebacterium aquaticum," Arcanobacterium, and Actinomyces. Case reports claiming disease associations of coryneform bacteria are critically reviewed. Minimal microbiological requirements for publications on disease associations of coryneform bacteria are proposed. PMID:8993861

  1. New Technologies in Clinical Microbiology

    Wolk, Donna M.; Dunne, W. Michael

    2011-01-01

    Rapid identification of microorganisms in the clinical microbiology laboratory can be of great value for selection of optimal patient management strategies for infections caused by bacteria, viruses, fungi, mycobacteria, and parasites. Rapid identification of microorganisms in clinical samples enables expedient de-escalation from broad-spectrum agents to targeted antimicrobial therapy. The switch to tailored therapy minimizes risks of antibiotics, namely, disruption of normal flora, toxic side effects, and selective pressure. There is a critical need for new technologies in clinical microbiology, particularly for bloodstream infections, in which associated mortality is among the highest of all infections. Just as importantly, there is a need for the clinical laboratory community to embrace the practices of evidence-based interventional laboratory medicine and collaborate in translational research projects to establish the clinical utility, cost benefit, and impact of new technologies.

  2. Paradigm change in evolutionary microbiology.

    PubMed

    O'Malley, Maureen A; Boucher, Yan

    2005-03-01

    Thomas Kuhn had little to say about scientific change in biological science, and biologists are ambivalent about how applicable his framework is for their disciplines. We apply Kuhn's account of paradigm change to evolutionary microbiology, where key Darwinian tenets are being challenged by two decades of findings from molecular phylogenetics. The chief culprit is lateral gene transfer, which undermines the role of vertical descent and the representation of evolutionary history as a tree of life. To assess Kuhn's relevance to this controversy, we add a social analysis of the scientists involved to the historical and philosophical debates. We conclude that while Kuhn's account may capture aspects of the pattern (or outcome) of an episode of scientific change, he has little to say about how the process of generating new understandings is occurring in evolutionary microbiology. Once Kuhn's application is limited to that of an initial investigative probe into how scientific problem-solving occurs, his disciplinary scope becomes broader. PMID:16120264

    2006-02-01

    Multimedia processing in battery powered mobile communication devices is pushing their computing power requirements to the level of desktop computers. At the same time the energy dissipation limit stays at 3W that is the practical maximum to prevent the devices from becoming too hot to handle. In addition, several hours of active usage time should be provided on battery power. During the last ten years the active usage times of mobile communication devices have remained essentially the same regardless of big energy efficiency improvements at silicon level. The reasons can be traced to the design paradigms that are not explicitly targeted to creating energy efficient systems, but to facilitate implementing complex software solutions by large teams. Consequently, the hardware and software architectures, including the operating system principles, are the same for both mainframe computer system and current mobile phones. In this paper, we consider the observed developments against the needs of video processing in mobile communication devices and consider means of implementing energy efficient video codecs both in hardware and software. Although inflexible, monolithic video acceleration hardware is an attractive solution, while software based codecs are becoming increasingly difficult to implement in an energy efficient manner due to increasing system complexity. Approaches that combine both the flexibility of software and energy efficiency of hardware remain to be seen.

    1987-01-01

    Experience with radioactive fallout, with organic contaminants and with heavy metals has amply demonstrated that cross-media transfers are common and that understanding the transport, cycling, and fate of these contaminants requires a multimedia approach. Nonetheless, pollutants with similar physical and chemical attributes may follow markedly different pathways. The frequency of exceptions to predictions based on simplistic models is also sufficient to show that direct investigation of environmental contamination is essential to confirm validity of models used for conceptualizing a problem or for control. Modeling based on multimedia premises and regulatory controls that encompass multimedia considerations are challenged by a dilemma, however. First, the development of multimedia models or regulatory frameworks represents simplification and generalization. This is true for several reasons: (1) inadequate understanding of physical and environmental factors which control specific cross-media transfer; (2) the absence of specific data on certain multimedia pollutant concentrations; (3) even the most powerful computers do not have sufficient speed and capacity to deal with the known complexities of natural systems. On the other hand, for contaminants such as mercury, it may be necessary to include great detail; the overall distribution in the environment may be less important than the rate of some minor process. With sufficient experience and good judgment of what can be ignored, the simplifications and generalizations can be made. For the present, and for the foreseeable future, however, they absolutely must be accompanied by thorough field validation and monitoring.

  9. Use of interactive multimedia disks in the applied environmental sciences program at the Oregon Institute of Technology

    NASA Astrophysics Data System (ADS)

    Jones, Charles R.

    Although a number of studies have been performed regarding the use of interactive multimedia disks in education, none were found which investigated their effect on either retention or recruitment for universities. The purpose of this case study was to gather information regarding student and teacher perceptions on the use of interactive multimedia disks and their effect on retention and recruitment. The primary source of data for this case study was student and teacher interviews. A purposive sample of students taking courses using the interactive multimedia disks in course at the Oregon Institute of Technology and at two Oregon high schools was chosen for the case study. Major findings of the case study were as follows: (1) Students interviewed in this case study perceived the interactive multimedia disk-based instructional method to be equally as effective as the lecture method. (2) Time flexibility in class scheduling was slightly more beneficial to female students than male students and the lack of instructor-led classroom interaction was more of a problem for female students than male students. (3) There was no difference in the perceptions of the college students and the high school students regarding the benefits and drawbacks of the interactive multimedia disk-based classes. (4) The flexible class scheduling made possible through the use of interactive multimedia disks influences some Oregon Institute of Technology students to stay and complete their degree programs. (5) There is some potential for interactive multimedia disk-based courses to be a recruiting tool. However, there is no evidence that it has been a successful recruiting tool for the Oregon Institute of Technology yet.

    Although several microbiological mastitis diagnostic tools are currently available, dairy farmers rarely use them to base treatment decisions on. In this study, we conducted a telephone interview among 195 randomly selected Dutch dairy farmers to determine their current use of and their need for microbiological diagnostics for clinical mastitis (CM), subclinical mastitis (SCM), and dry-cow treatment (DCT), followed by the test characteristics they consider important. A structured questionnaire was used, based on face-to-face interviews previously held with other farmers. The answers were registered in a database and analyzed using descriptive statistics and univariable and multivariable models. Antimicrobial treatment decisions for CM, SCM, and DCT were mainly based on clinical signs and somatic cell count. In case of CM, 34% of farmers indicated that they currently submit milk samples for bacteriological culture (BC). This would increase to 71% if an on-farm test resulting in treatment advice within 12 h were available. For SCM, use would increase from 22 to 55%, and for DCT, from 7 to 34%, if the same 12-h test were available. For CM and DCT, the preferred test outcome was advice on which antibiotic to use, according to 58 and 15% of the farmers, respectively. For SCM, the preferred test outcome was the causative bacterium for 38% of the farmers. Farmers who currently submit CM milk samples for BC were 13.1 times more likely to indicate, as the preferred test outcome, advice on which antibiotic to use, compared with farmers who do not currently submit CM milk samples for BC. Fourteen percent of the farmers indicated not being interested at all in microbiological mastitis diagnostics for CM. For SCM and DCT, 27 and 55%, respectively, were not interested in microbiological mastitis diagnostics. Regarding test characteristics that farmers considered important, reliability was most often indicated (44-51% of the farmers). Additionally, a preferred time-to-result of

    1996-12-31

    The Binding Architecture is an open architecture for building multimedia networks that must guarantee Quality of Service (QOS). In this paper, we explore the notion of a service in the Binding Architecture and propose a conceptual model for building scalable multimedia distribution services based on it. We begin first by examining the relation between resources, their abstractions and the services that can be built from them and use this to derive a general model for binding. Based on this model, we identify a general set of capabilities required for building any multimedia distribution service. We also describe how these capabilities can be incorporated into our view of the service creation process. Finally, we augment our discussion with the description of an example service which we have developed using this paradigm.

In the context of a project put forward at the Communications Research Centre Canada to deliver interactive multimedia to remote and rural areas in Canada, a receiver capable of extracting Internet Packets (IP) as well as video and audio transport streams (TS) based on the Advanced Television Systems Committee (ATSC) terrestrial digital television system is developed. This paper describes the design, implementation, functionality, as well as several applications of this receiver which plays an important role in the interactive multimedia datacasting system. The ATSC terrestrial transmission chain from the server at the transmitter site to the receiver (client) at the end-user's premise is presented. A number of possible implementations for a return channel are proposed. Preliminary results of laboratory trials as well as plans for field trials are presented.

  3. Multimedia Environmental Distribution of Nanomaterials

    NASA Astrophysics Data System (ADS)

    Liu, Haoyang Haven

    Engineered nanomaterials (ENMs), which may be released to the environment due to human-related activities, can move across environmental phase boundaries and be found in most media. Given the rapid development and growing applications of nanotechnology, there is concern and thus the need to assess the potential environmental impact associated with ENMs. Accordingly, a modeling platform was developed to enable evaluation of the dynamic multimedia environmental distribution of ENMs (MendNano) and the range of potential exposure concentrations of ENMs. The MendNano was based on a dynamic multimedia compartmental modeling approach that was guided by detailed analysis of the agglomeration of ENMs, life-cycle analysis based estimates of their potential release to the environment, and incorporation of mechanistic sub-models of various intermedia transport processes. Model simulations for various environmental scenarios indicated that ENM accumulation in the sediment increased significantly with increased ENMs attachment to suspended solids in water. Atmospheric dry and wet depositions can be important pathways for ENMs input to the terrestrial environment in the absence of direct and distributed ENM release to soil. Increased ENM concentration in water due to atmospheric deposition (wet and dry) is expected as direct ENM release to water diminishes. However, for soluble ENMs dissolution can be the dominant pathway for suspended ENM removal from water even compared to advective transport. For example, simulations for Los Angeles showed that dry deposition, rain scavenging, and wind dilution can remove 90% of ENMs from the atmospheric airshed in ~100-230 days, ~2-6 hrs, and ~0.5-2 days, respectively. For the evaluated ENMs (metal, metal oxides, carbon nanotubes (CNT), nanoclays), mass accumulation in the multimedia environment was mostly in the soil and sediment. Additionally, simulation results for TiO2 in Los Angeles demonstrates that the ENM concentrations in air and

    Many systems have been proposed for protecting the intellectual property of multimedia authors and owners from the public at large, who have access to the multimedia only after it is published. In this paper, we consider the problem of protecting authors' intellectual property rights from insiders, such as collaborating authors and producers, who interact with the creative process before publication. We describe the weaknesses of standard proof-of-ownership watermarking approaches against dishonest insiders and propose several possible architectures for systems that avoid these weaknesses. We further show how these architectures can be adapted for fingerprinting in the presence of dishonest insiders.

    Multimedia modelers from the United States Environmental Protection Agency (EPA) and the United States Department of Energy (DOE) collaborated to conduct a detailed and quantitative benchmarking analysis of three multimedia models. The three models--RESRAD (DOE), MMSOILS (EPA), and MEPAS (DOE)--represent analytically-based tools that are used by the respective agencies for performing human exposure and health risk assessments. The study is performed by individuals who participate directly in the ongoing design, development, and application of the models. Model form and function are compared by applying the models to a series of hypothetical problems, first isolating individual modules (e.g., atmospheric, surface water, groundwater) and then simulating multimedia-based risk resulting from contaminant release from a single source to multiple environmental media. Study results show that the models differ with respect to environmental processes included (i.e., model features) and the mathematical formulation and assumptions related to the implementation of solutions. Depending on the application, numerical estimates resulting from the models may vary over several orders-of-magnitude. On the other hand, two or more differences may offset each other such that model predictions are virtually equal. The conclusion from these results is that multimedia models are complex due to the integration of the many components of a risk assessment and this complexity must be fully appreciated during each step of the modeling process (i.e., model selection, problem conceptualization, model application, and interpretation of results).

    1991-01-01

    This panel discussion convened in Houston, Texas, at the Lunar and Planetary Institute, on November 6 to 8, 1989, to review NASA's plans for microbiology on Space Station Freedom. A panel of distinguished scientists reviewed, validated, and recommended revisions to NASA's proposed acceptability standards for air, water, and internal surfaces on board Freedom. Also reviewed were the proposed microbiology capabilities and monitoring plan, disinfection procedures, waste management, and clinical issues. In the opinion of this advisory panel, ensuring the health of the Freedom's crews requires a strong goal-oriented research effort to determine the potential effects of microorganisms on the crewmembers and on the physical environment of the station. Because there are very few data addressing the fundamental question of how microgravity influences microbial function, the panel recommended establishing a ground-based microbial model of Freedom, with subsequent evaluation using in-flight shuttle data. Sampling techniques and standards will be affected by both technological advances in microgravity-compatible instrumentation, and by changes in the microbial population over the life of the station.

    Of the large amount of funds spent each year in this country on construction and remodeling of biomedical research facilities, a significant portion is directed to laboratories handling infectious microorganisms. This paper is intended for the scientific administrators, architects, and engineers concerned with the design of new microbiological facilities. It develops and explains the concept of primary and secondary barriers for the containment of microorganisms. The basic objectives of a microbiological research laboratory, (i) protection of the experimenter and staff, (ii) protection of the surrounding community, and (iii) maintenance of experimental validity, are defined. In the design of a new infectious-disease research laboratory, early identification should be made of the five functional zones of the facility and their relation to each other. The following five zones and design criteria applicable to each are discussed: clean and transition, research area, animal holding and research area, laboratory support, engineering support. The magnitude of equipment and design criteria which are necessary to integrate these five zones into an efficient and safe facility are delineated.

    Liu, Haoyang Haven; Cohen, Yoram

    2014-03-18

    A compartmental multimedia model was developed to enable evaluation of the dynamic environmental multimedia mass distribution and concentrations of engineered nanomaterials (ENMs). The approach considers the environment as a collection of compartments, linked via fundamental environmental intermedia transport processes. Model simulations for various environmental scenarios indicated that ENM accumulation in the sediment increased significantly with increased ENMs attachment to suspended solids in water. Atmospheric dry and wet depositions can be important pathways for ENMs input to the terrestrial environment in the absence of direct and distributed ENM release to soil. Increased ENM concentration in water due to atmospheric deposition (wet and dry) is expected as direct ENM release to water diminishes. However, for soluble ENMs dissolution can be the dominant pathway for suspended ENM removal from water even compared to advection. Mass accumulation in the multimedia environment for the evaluated ENMs (metal, metal oxides, carbon nanotubes (CNT), nanoclays) was mostly in the soil and sediment. The present modeling approach, as illustrated via different test cases, is suited for "what if" first tier analyses to assess the multimedia mass distribution of ENMs and associated potential exposure concentrations.

  14. MPEG-7 multimedia-based query format

    NASA Astrophysics Data System (ADS)

    Chang, Wo

    2006-08-01

    Searching multimedia content for image, audio, and video is getting more attention especially for personal media content due to the affordability of consumer electronic devices such as MP3 recordable players, digital cameras, DV camcorders, and well-integrated smart phones. The precise search and retrieval of the content derived from these devices can be a very challenging task. Many leading edge search engine vendors have been applying sophisticated and advanced indexing and retrieval techniques on various text-based document formats, but when it comes to retrieving multimedia content, searching based on the media clip filename is the most common practice. As a result, there is an imprecise and ineffective user experience for searching multimedia content. This paper presents a new development underway from a joint effort between International Organization for Standardization (ISO)/International Electrotechnial Commission (IEC) Subcommittee (SC) 29 Working Group (WG) 11 MPEG (Moving Picture Experts Group) and WG1 JPEG (Joint Picture Experts Group) for a universal standard query format called MPEG-7 Query Format (MP7QF) as a means to enable a good user experience for consumers searching multimedia content. It also provides the industry with a unified way to accept and respond to user queries. This paper presents the core requirements for such a universal query format.

    Does an online, multimedia case study influence students' performance, motivation, and perceptions of science in collegiate level biology classes, and if so, how? One hundred and eight students in 5 classes from 4 campuses in the United States and Puerto Rico participated in data collection (performance tests, surveys and focus group interviews). Pre- and post-test results increased after students participated in the learning environment (F(1, 80) = 17.256, p ≤ 0.01, η2 = 0.177). Student confidence in their knowledge also increased. During focus group interviews students reported that the project was a good learning experience (95 %), would help with future classes or careers (87 %), and stimulated student curiosity by demonstrating the application of theoretical knowledge in real-world situations (64 %). The learning environment motivated students by making material relevant, which resulted in better performance. This pedagogical tool is not instructor dependent, and is adaptable.

  6. Rapid methods and automation in dairy microbiology.

    1993-10-01

    The importance of microbiology to the dairy industry has been demonstrated by recent outbreaks of foodborne illness associated with consumption of milk and dairy products that had been contaminated with pathogenic organisms or toxins. Undesirable microorganisms constitute the primary hazard to safety, quality, and wholesomeness of milk and dairy foods. Consequently, increased emphasis has been placed on the microbiological analysis of milk and dairy products designed to evaluate quality and to ensure safety and regulatory compliance. The focus of dairy microbiology, however, remains largely on conventional methods: plate counts, most probable numbers, and dye reduction tests. These methods are slow, tedious, intensive in their requirements for material and labor, and often not suitable for assessing the quality and shelf-life of perishable dairy foods. With the exception of coliforms, Salmonella, and Staphylococcus aureus, isolation and characterization of various organisms occurring in milk and milk products are seldom a part of the routine microbiological analysis in the dairy industry. Recent emphasis on the programs based on HACCP (Hazard Analysis and Critical Control Points) for total quality management in the dairy industry and increased demand for microbiological surveillance of products, process, and environment have led to increased interest in rapid methods and automation in microbiology. Several methods for rapid detection, isolation, enumeration, and characterization of microorganisms are being adapted by the dairy industry. This presentation reviews rapid methods and automation in microbiology for microbiological analysis of milk and dairy products. PMID:8227634

    The golden opportunities represented by multimedia systems have been recognized by many. The risk and cost involved in developing the products and the markets has led to a bonanza of unlikely consortia of strange bedfellows. The premier promoter of personal computing systems, Apple Computer, has joined forces with the dominant supplier of corporate computing, IBM, to form a multimedia technology joint venture called Kaleida. The consumer electronics world's leading promoter of free trade, Sony, has joined forces with the leader of Europe's protectionist companies, Philips, to create a consumer multimedia standard called CD-I. While still paying lip service to CD-I, Sony and Philips now appear to be going their separate ways. The software world's most profitable/fastest growing firm, Microsoft, has entered into alliances with each and every multimedia competitor to create a mish mash of product classes and defacto standards. The battle for Multimedia Standards is being fought on all fronts: on standards committees, in corporate strategic marketing meetings, within industry associations, in computer retail stores, and on the streets. Early attempts to set proprietary defacto standards were fought back, but the proprietary efforts continue with renewed vigor. Standards committees were, as always, slow to define specifications, but the official standards are now known nd being implemented; ... but the proprietary efforts continue with renewed vigor. Ultimately, the buyers will decide -- like it or not. Success by the efforts to establish proprietary defacto standards could prove to be a boon to the highly creative and inventive U.S. firms, but at the cost of higher prices for consumers and slower market growth. Success by the official standards could bring lower prices for consumers and fast market growth, but force the higher-wage/higher-overhead U.S. firms to compete on a level playing field. As is always the case, you can't have your cake and eat it too.

    In times of increasing relevance of alternative energy resources the utilization of geothermal energy and subsurface energy storage gains importance and arouses increasing interest of scientists. The research project “AquiScreen” investigates the operational reliability of geothermally used groundwater systems under microbial, geochemical, mineralogical and petrological aspects. Microbiological analyses based on fluid and solid phases of geothermal systems are conducted to evaluate the impact of microbial populations on these systems. The presentation focuses on first results obtained from microbiological monitoring of geothermal plants located in two different regions of Germany: the North German Basin and the Molasse Basin in the southern part characterized by different salinities and temperatures. Fluid and filter samples taken during regular plant operation were investigated using genetic fingerprinting based on PCR-amplified 16S rRNA genes to characterize the microbial biocenosis of the geothermal aquifer. Sequencing of dominant bands of the fingerprints and the subsequent comparison to 16S rRNA genes from public databases enables a correlation to metabolic classes and provides information about the biochemical processes in the deep biosphere. The genetic profiles revealed significant differences in microbiological community structures of geothermal aquifers investigated. Phylogenetic analyses indicate broad metabolical diversity adapted to the specific conditions in the aquifers. Additionally a high amount of so far uncultivated microorganisms was detected indicating very specific indigenous biocenosis. However, in all geothermal plants bacteria were detected despite of fluid temperatures from 45° to 120°C. The identified microorganisms are closely related to thermophilic and hyperthermophilic species detectable in hot wells and hot springs, like Thermus scotoductus and Thermodesulfovibrio yellowstonii, respectively. Halophilic species were detected in

  12. An innovative approach to multimedia waste reduction: Measuring performance for environmental cleanup projects

    SciTech Connect

    Phifer, B.E. Jr.; George, S.M. )

    1993-04-01

    One of the greatest challenges we now face in environmental cleanup is measuring the progress of minimizing multimedia transfer releases and achieving waste reduction. Briefly, multimedia transfer refers to the air, land, and water where pollution is not controlled, concentrated, and moved from one medium to another. An example of multimedia transfer would be heavy metals in wastewater sludges moved from water to land disposal. Over $2 billion has been budgeted for environmental restoration site cleanups by the Department of Energy (DOE) for FY 1994. Unless we reduce the huge waste volumes projected to be generated in the near future, then we will devote more and more resources to the management and disposal of these wastes. To meet this challenge, the Martin Marietta Energy Systems, Inc., Oak Ridge Environmental Restoration (ER) Program has explored the value of a multimedia approach by designing an innovative Pollution Prevention Life-Cycle Model. The model consists of several fundamental elements (Fig. 1) and addresses the two major objectives of data gathering and establishing performance measures. Because the majority of projects are in the remedial investigation phase, the focus is on the prevention of unnecessary generation of investigation-derived waste and multimedia transfers at the source. A state-of-the-art tool developed to support the life-cycle model for meeting these objectives is the Numerical Scoring System (NSS), which is a computerized, user-friendly data base system for information management, designed to measure the effectiveness of pollution prevention activities in each phase of the ER Program. This report contains a discussion of the development of the Pollution Prevention Life-Cycle Model and the role the NSS will play in the pollution prevention programs in the remedial investigation phase of the ER Program at facilities managed by Energy Systems for DOE.

    Nowadays, quality of service (QoS) is very popular in various research areas like distributed systems, multimedia real-time applications and networking. The requirements of these systems are to satisfy reliability, uptime, security constraints and throughput as well as application specific requirements. The real-time multimedia applications are commonly distributed over the network and meet various time constraints across networks without creating any intervention over control flows. In particular, video compressors make variable bit-rate streams that mismatch the constant-bit-rate channels typically provided by classical real-time protocols, severely reducing the efficiency of network utilization. Thus, it is necessary to enlarge the communication bandwidth to transfer the compressed multimedia streams using Flexible Time Triggered- Enhanced Switched Ethernet (FTT-ESE) protocol. FTT-ESE provides automation to calculate the compression level and change the bandwidth of the stream. This paper focuses on low-latency multimedia transmission over Ethernet with dynamic quality-of-service (QoS) management. This proposed framework deals with a dynamic QoS for multimedia transmission over Ethernet with FTT-ESE protocol. This paper also presents distinct QoS metrics based both on the image quality and network features. Some experiments with recorded and live video streams show the advantages of the proposed framework. To validate the solution we have designed and implemented a simulator based on the Matlab/Simulink, which is a tool to evaluate different network architecture using Simulink blocks. PMID:25170768

    Summary: This review aims to discuss expert systems in general and how they may be used in medicine as a whole and clinical microbiology in particular (with the aid of interpretive reading). It considers rule-based systems, pattern-based systems, and data mining and introduces neural nets. A variety of noncommercial systems is described, and the central role played by the EUCAST is stressed. The need for expert rules in the environment of reset EUCAST breakpoints is also questioned. Commercial automated systems with on-board expert systems are considered, with emphasis being placed on the “big three”: Vitek 2, BD Phoenix, and MicroScan. By necessity and in places, the review becomes a general review of automated system performances for the detection of specific resistance mechanisms rather than focusing solely on expert systems. Published performance evaluations of each system are drawn together and commented on critically. PMID:21734247

    Dental abscess is a frequently occurring infectious process known to the health practice. The fate of the infection depends on the virulence of the bacteria, host resistance factors, and regional anatomy. Serious consequences arising from the spread of a dental abscess lead to significant morbidity and mortality. Acute dental abscess is polymicrobial, comprising of strict anaerobes, such as anaerobic cocci, Prevotella, Fusobacterium species, and facultative anaerobes, such as viridans group streptococci and the Streptococcus anginosus group. Numerous novel, uncultivable and fastidious organisms have been identified as potential pathogens with the use of non-culture techniques. The majority of localized dental abscesses respond to surgical treatment while the use of antimicrobials is limited to severe spreading infections. There is a need for good-quality clinical trials of sufficient size to identify the ideal treatment. The microbiology of the acute dentoalveolar abscess and its treatment in the light of improved culture and diagnostic methods are reviewed. PMID:24348613

    Technical evolutions in the field of information technology have changed many aspects of the industries and the life of human beings. Internet and broadcasting technologies act as core ingredients for this revolution. Various new services that were never possible are now available to general public by utilizing these technologies. Multimedia service via IP networks becomes one of easily accessible service in these days. Technical advances in Internet services, the provision of constantly increasing network bandwidth capacity, and the evolution of multimedia technologies have made the demands for multimedia streaming services increased explosively. With this increasing demand Internet becomes deluged with multimedia traffics. Although multimedia streaming services became indispensable, the quality of a multimedia service over Internet can not be technically guaranteed. Recently users demand multimedia service whose quality is competitive to the traditional TV broadcasting service with additional functionalities. Such additional functionalities include interactivity, scalability, and adaptability. A multimedia that comprises these ancillary functionalities is often called richmedia. In order to satisfy aforementioned requirements, Interactive Scalable Multimedia Streaming (ISMuS) platform is designed and developed. In this paper, the architecture, implementation, and additional functionalities of ISMuS platform are presented. The presented platform is capable of providing user interactions based on MPEG-4 Systems technology [1] and supporting an efficient multimedia distribution through an overlay network technology. Loaded with feature-rich technologies, the platform can serve both on-demand and broadcast-like richmedia services.

    2004-05-01

    Predictive microbiology (predictive modelling PM), in spite of its limits and short-comings, may often contribute to a reduction of the problems arising when HACCP systems are established or microbiological risk assessment is done. Having identified the agents which constitute a risk and the contamination rate and density in the raw material, the influences of production steps and storage on these microorganisms have to be examined. Finally, there should be an exposure assessment, i.e. an estimate of the contamination density in the final product at the time of consumption. Should the exposure assessment together with data from dose response assessments reveal a potential for intake of inacceptable numbers of organisms, the risk identified has to be characterized. As a consequence, risk management should result in a modification of the composition of the product and/or of the production process so that the risk does not surpass an acceptable limit. For this approach it is indispensable to have product- and process-specific information on the multiplication of pathogens prior to heat treatment, on reduction of their density by thermal treatment and on growth or dying of organisms having survived heat treatment or penetrated into the product after heat treatment as post-process contaminant. Commonly, challenge tests are conducted to provide such information. But they are time consuming and, as their results are only valid for the specific product tested and the conditions prevailing during the experiment, the have to be repeated if there is any modification of intrinsic or extrinsic factors. At least partially, the PM may replace the challenge tests. The efficiency of the models is rated particularly high if they are used already at the stage of product development when the question has to be answered whether a planned recipe or process of production are already save or have to be modified to become save.

  2. Online reinforcement learning for dynamic multimedia systems.

    PubMed

    Mastronarde, Nicholas; van der Schaar, Mihaela

    2010-02-01

    In our previous work, we proposed a systematic cross-layer framework for dynamic multimedia systems, which allows each layer to make autonomous and foresighted decisions that maximize the system's long-term performance, while meeting the application's real-time delay constraints. The proposed solution solved the cross-layer optimization offline, under the assumption that the multimedia system's probabilistic dynamics were known a priori, by modeling the system as a layered Markov decision process. In practice, however, these dynamics are unknown a priori and, therefore, must be learned online. In this paper, we address this problem by allowing the multimedia system layers to learn, through repeated interactions with each other, to autonomously optimize the system's long-term performance at run-time. The two key challenges in this layered learning setting are: (i) each layer's learning performance is directly impacted by not only its own dynamics, but also by the learning processes of the other layers with which it interacts; and (ii) selecting a learning model that appropriately balances time-complexity (i.e., learning speed) with the multimedia system's limited memory and the multimedia application's real-time delay constraints. We propose two reinforcement learning algorithms for optimizing the system under different design constraints: the first algorithm solves the cross-layer optimization in a centralized manner and the second solves it in a decentralized manner. We analyze both algorithms in terms of their required computation, memory, and interlayer communication overheads. After noting that the proposed reinforcement learning algorithms learn too slowly, we introduce a complementary accelerated learning algorithm that exploits partial knowledge about the system's dynamics in order to dramatically improve the system's performance. In our experiments, we demonstrate that decentralized learning can perform equally as well as centralized learning, while

    Acidified specialty products or condiments are among the most microbiologically stable and safe food products. Often formulated, packaged, and distributed without heat treatments, they are microbiologically stable indefinitely at ambient temperatures in unopened containers. The packaged, acidified products are often intended for multiple uses, exposing them at the points of consumption to numerous opportunities for contamination with microorganisms. Nonetheless, they remain resistant to microbiological spoilage for many months, often under refrigerated conditions that are used to retard chemical reactions, flavor changes, and yeast growth.

    Multimedia modelers from the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy (DOE) are collaborating to conduct a comprehensive and quantitative benchmarking analysis of four intermedia models: DOE's Multimedia Environmental Pollutant Assessment System (MEPAS), EPA's MMSOILS, EPA's PRESTO, and DOE's RESidual RADioactivity (RESRAD). These models represent typical analytically, semi-analytically, and empirically based tools that are utilized in human risk and endangerment assessments for use at installations containing radioactive and/or hazardous contaminants. Although the benchmarking exercise traditionally emphasizes the application and comparison of these models, the establishment of a Conceptual Site Model (CSM) should be viewed with equal importance. This paper reviews an approach for developing a CSM of an existing, real-world, Sr-90 plume at DOE's Hanford installation in Richland, Washington, for use in a multimedia-based benchmarking exercise bet ween MEPAS, MMSOILS, PRESTO, and RESRAD. In an unconventional move for analytically based modeling, the benchmarking exercise will begin with the plume as the source of contamination. The source and release mechanism are developed and described within the context of performing a preliminary risk assessment utilizing these analytical models. By beginning with the plume as the source term, this paper reviews a typical process and procedure an analyst would follow in developing a CSM for use in a preliminary assessment using this class of analytical tool.

    A comprehensive approach to the access of archival collections necessitates the interplay of various types of metadata standards. Each of these standards fulfills its own part within the context of a 'metadata infrastructure'. Besides this, it should be noted that present-day digital libraries are often limited to the management of mainly textual and image-based material. Archival Information Systems dealing with various media types are still very rare. There is a need for a methodology to deal with time-dependant media within an archival context. The aim of our research is to investigate and implement a number of tools supporting the content management multimedia data within digital collections. A flexible and extendible framework is proposed, based on the emerging Metadata Encoding and Transmission Standard (METS). Firstly, we will focus on the description of archival collections according to the archival mandates of provenance for the benefit of an art-historical research in an archive-theoretically correct manner. Secondly, we will examine the description tools that represent the semantics and structure of multimedia data. In this respect, an extension of the present archival metadata framework has been proposed to time-based media content delivered via standards such as the MPEG-7 multimedia content description standard.

    At many medical schools, the medical library assists faculty in finding and integrating new technology into the classroom, student laboratories, and lecture or small group sessions. Libraries also provide faculty with a place to do development. This paper recounts the author's experience creating software-based educational materials. In the process of creating the Slice of Life videodisc and developing and distributing other medical education software, techniques that do and do not work in producing multimedia for medical education became evident. Use of multimedia features and new modalities not possible with books, rather than development of electronic versions of texts and atlases, should be emphasized. Important human factors include collaboration, continuity, evaluation, and sharing of equipment, software, code, effort, expertise, and experiences. Distribution and technical support also are important activities in which medical libraries can participate. PMID:8004014

    Efficient encryption algorithms are essential to multimedia data security, since the data size is large and real-time processing is often required. After discussing limitations of previous work on multimedia encryption, we propose a novel methodology for confidentiality, which turns entropy coders into encryption ciphers by using multiple statistical models. The choice of statistical models and the order in which they are applied are kept secret as the key Two encryption schemes are constructed by applying this methodology to the Huffman coder and the QM coder. It is shown that security is achieved without sacrificing the compression performance and the computational speed. The schemes can be applied to most modern compression systems such as MPEG audio, MPEG video and JPEG/JPEG2000 image compression.

    Making technological advances in the field of human-machine interactions requires that the capabilities and limitations of the human perceptual system are taken into account. The focus of this report is an important mechanism of perception, visual selective attention, which is becoming more and more important for multimedia applications. We introduce the concept of visual attention and describe its underlying mechanisms. In particular, we introduce the concepts of overt and covert visual attention, and of bottom-up and top-down processing. Challenges related to modeling visual attention and their validation using ad hoc ground truth are also discussed. Examples of the usage of visual attention models in image and video processing are presented. We emphasize multimedia delivery, retargeting and quality assessment of image and video, medical imaging, and the field of stereoscopic 3D images applications. PMID:24489403

    Managing the timely access of information is a major challenge facing law enforcement agencies. One of the areas of greatest need is that of the case management process. During the course of FY98, the Office of National Drug Control Policy (ONDCP), the Counterdrug Technology Assessment Center (CTAC), the Idaho National Engineering and Environmental Laboratory (INEEL), and the Criminal Investigative Bureau (CIB) of the state of Idaho, created a Northwest testbed to develop and integrate a multimedia case management system. A system was developed to assist investigators in tracking and maintaining investigative cases and improving access to internal and external data resources. In this paper, we discuss the results of our case management system development and the ability to present state and federal information incorporating object oriented and multimedia techniques. We then outline our plans for future research and development.

  12. Multimedia Forensics Is Not Computer Forensics

    Böhme, Rainer; Freiling, Felix C.; Gloe, Thomas; Kirchner, Matthias

    The recent popularity of research on topics of multimedia forensics justifies reflections on the definition of the field. This paper devises an ontology that structures forensic disciplines by their primary domain of evidence. In this sense, both multimedia forensics and computer forensics belong to the class of digital forensics, but they differ notably in the underlying observer model that defines the forensic investigator’s view on (parts of) reality, which itself is not fully cognizable. Important consequences on the reliability of probative facts emerge with regard to available counter-forensic techniques: while perfect concealment of traces is possible for computer forensics, this level of certainty cannot be expected for manipulations of sensor data. We cite concrete examples and refer to established techniques to support our arguments.

    Training new users of complex machines is often an expensive and time-consuming process. This is particularly true for special purpose systems, such as those frequently encountered in DOE applications. This paper presents a computer-based training system intended as a partial solution to this problem. The system extends the basic virtual reality (VR) training paradigm by adding a multimedia component which may be accessed during interaction with the virtual environment. The 3D model used to create the virtual reality is also used as the primary navigation tool through the associated multimedia. This method exploits the natural mapping between a virtual world and the real world that it represents to provide a more intuitive way for the student to interact with all forms of information about the system.

    Bacteriophages are viruses that infect bacteria, and they are found everywhere their bacterial hosts are present, including the human body. To explore the presence of phages in clinical samples, we assessed 65 clinical samples (blood, ascitic fluid, urine, cerebrospinal fluid, and serum). Infectious tailed phages were detected in >45% of ascitic fluid and urine samples. Three examples of phage interference with bacterial isolation were observed. Phages prevented the confluent bacterial growth required for an antibiogram assay when the inoculum was taken from an agar plate containing lysis plaques, but not when taken from a single colony in a phage-free area. In addition, bacteria were isolated directly from ascitic fluid, but not after liquid enrichment culture of the same samples, since phage propagation lysed the bacteria. Lastly, Gram-negative bacilli observed in a urine sample did not grow on agar plates due to the high densities of infectious phages in the sample. PMID:27609086

    2009-04-01

    INTRODUCTION Matyka-Sarzynska and Sokolowska (2000) emphasize that peats and peat soils comprise large areas of Poland. The creation of soil begins when the formation of swamp has ended. Gawlik (2000) states that the degree of influence of the mucky process of organic soils on the differentiations of the conditions of growth and development of plants is mainly connected with the changes of moisture-retentive properties of mucks which constitute the material for these soils, and the loss of their wetting capacities. The above-mentioned changes, which usually occur gradually and show a clear connection with the extent of dehydration and, at times, with its duration, intensify significantly when the soils are under cultivation. The mucky process of peat soils leads to transformations of their physical, chemical and biological properties. The main ingredient of peat soils is organic substance. The substance is maintained inside them by the protective activity of water. The process of land improvement reduces the humidity of the environment, and that Intensifies the pace of the activity of soil microorganisms which cause the decay of organic substance. The decay takes place in the direction of two parallel processes: mineralization and humification. All groups of chemical substances constituting peat undergo mineralization. Special attention should be called to the mineralization of carbon and nitrogen compounds, which constitute a large percentage of theorganic substance of the peat organic mass. Okruszko (1976) has examined scientificbases of the classification of peat soils depending on the intensity of the muck process. The aim of this publication was to conduct a microbiological characteristic of selected mucky material. METHODS AND MATERIALS Soil samples used in the experiments were acquired from the Leczynsko-Wlodawski Lake Region, a large area of which constitutes a part of the Poleski National Park, which is covered to a large extent with high peat bogs.

    Cellular Microbiology by P. Cossart, P. Boquet, S. Normark and R. Rappuoli ASM Press (2000) pp. 392. ISBN 1-55581-157-4 $75.95 The term 'cellular microbiology' was coined by the editors of this book in 1996. Since then several volumes and journals addressing this subject have been produced and Cellular Microbiology is a valuable contribution to an exciting field. In studying the pathogenesis of infectious diseases it is clear that an understanding of the interaction between the host and the pathogen requires a knowledge of both and here we have an excellent source of information for the integrated study of microbiology and cell biology. The first two chapters are a useful general introduction to the two subject areas and will be particularly useful for scientists of the 'opposite' discipline i.e. microbiologists will find the cell biology section particularly useful and vice versa. The chapters then progress through the encounter of the pathogen with the eukaryotic cell, from the interactions occurring at the cell surface, the mechanisms of attachment and the interaction with the cell cytoskeleton, to the action of bacterial toxins and the consequences of these interactions. Although the book relates mainly to the interaction of bacteria with the host there are also many interesting discussions on parasites and some fungi. Later chapters describe the interaction of pathogens with the immune system, covering the use of bacterial products as tools in cell biology and describing some of the underlying methodology involved in cellular microbiology; there are also interesting chapters on Type III and Type IV secretion systems. As with any textbook in a rapidly expanding area there is a danger that the information contained will rapidly become dated. This may apply especially to the chapters on secretion systems which are the subject of intense research effort. The chapters are all relatively short and can be read as stand alone 'mini-reviews' of the area. This will be

    Interpersonal communication among a group of users employing different media types is becoming more and more widespread in computing and telecommunications. Group communication places a variety of new requirements onto the underlying communications architecture and although many existing protocols and services do offer some limited support for multicast group communication, these new requirements make it difficult to find efficient and comprehensive solutions. The impact of multimedia group communication on the communication system and the way in which existing systems, international standardization bodies and researchers cope with these challenges is the subject of this paper. First the characteristics and requirements of multimedia group applications are discussed and illustrated by examples of existing group applications. Subsequently a survey of the kind of support available in today's communication system is presented. In addition the ongoing discussion about the standardization of group communication within ISO and ITU and the direction these efforts take is briefly summarized. Further, some selected examples of research projects which deal with different communication and protocol related aspects of multimedia group communication are presented which give an indication of the trends in this area.

  4. Efficient Access Control in Multimedia Social Networks

    NASA Astrophysics Data System (ADS)

    Sachan, Amit; Emmanuel, Sabu

    Multimedia social networks (MMSNs) have provided a convenient way to share multimedia contents such as images, videos, blogs, etc. Contents shared by a person can be easily accessed by anybody else over the Internet. However, due to various privacy, security, and legal concerns people often want to selectively share the contents only with their friends, family, colleagues, etc. Access control mechanisms play an important role in this situation. With access control mechanisms one can decide the persons who can access a shared content and who cannot. But continuously growing content uploads and accesses, fine grained access control requirements (e.g. different access control parameters for different parts in a picture), and specific access control requirements for multimedia contents can make the time complexity of access control to be very large. So, it is important to study an efficient access control mechanism suitable for MMSNs. In this chapter we present an efficient bit-vector transform based access control mechanism for MMSNs. The proposed approach is also compatible with other requirements of MMSNs, such as access rights modification, content deletion, etc. Mathematical analysis and experimental results show the effectiveness and efficiency of our proposed approach.

    Recycling of organic waste appeals to more and more people. The aim of this study was to evaluate the microbiological contamination around organic waste bins at three distances over a 12-month period. Contamination near the customary trash of control households was evaluated at the beginning to ensure that there is no recruitment bias. Air samples using the MAS 100 impactor were carried out in 38 dwellings that do household waste composting and in 10 dwellings of controls. Collection of particles by CIP 10 rotating cup sampler and dust samples collected by electrostatic dust collector cloths were acquired in dwellings that do household waste composting. Samples were analyzed by culture and by real-time quantitative PCR. Information about dwelling characteristics and inhabitant practices was obtained by a standardized questionnaire. The genera most often isolated were Penicillium, Aspergillus, Cladosporium and Streptomyces. Near the organic waste bins, bioaerosol samples showed an increase of Acarus siro (P = 0.001). Sedimented dust analyses highlighted an increase of A. siro, Wallemia sebi, Aspergillus versicolor, and Cladosporium sphaerospermum concentrations after a 12-month survey compared to the beginning. Composting favors microorganism development over time, but does not seem to have an effect on the bioaerosol levels and the surface microbiota beyond 0.5 m from the waste bin. PMID:26299932

    This invention relates to testing processes for toxicity involving microorganisms and, more particularly, to testing processes for toxicity involving bioluminescent organisms. The present known method of testing oil-well drilling fluids for toxicity employs the mysid shrimp (Mysidopsis bahia) as the assay organism. The shrimp are difficult to raise and handle as laboratory assay organisms. This method is labor-intensive, because it requires a assay time of about 96 hours. Summary of the Invention: A microbiological assay in which the assay organism is the dinoflagellate, Pyrocystis lunula. A sample of a substance to be assayed is added to known numbers of the bioluminescent dinoflagellate and the mixture is agitated to subject the organisms to a shear stress causing them to emit light. The amount of light emitted is measured and compared with the amount of light emitted by a known non-toxic control mixture to determine if there is diminution or non-diminution of light emitted by the sample under test which is an indication of the presence or absence of toxicity, respectively. Accordingly, an object of the present invention is the provision of an improved method of testing substances for toxicity. A further object of the invention is the provision of an improved method of testing oil-well drilling fluids for toxicity using bioluminescent dinoflagellate (Pyrocystis lunula).

    The diagnosis of wound infection is based on clinical signs and local and/or systemic inflammation. Therefore, the examination has a major role in the diagnosis of infected lesions of the foot. Once the clinical diagnosis of infection is made, the next step is to determine the etiology with the aim to undertake a rational and appropriate treatment. The most reliable method for assessing microbiological etiology is the specimen of material from infected lesion to perform a bacterioscopic examination and culture. The microorganisms involved in the etiology of diabetic foot depends on the type of injury and on specific patient features (antibiotic therapy, previous hospitalization). The most frequently detected pathogen is Staphylococcus aureus. Mild infections are mostly caused by Gram positive cocci, with a prevalence of S. aureus. Moderate infections are mostly supported by pyogenic Gram positive cocci, but also Gram-negative bacteria can be involved. In severe infections the etiology is polymicrobial. As regards the involvement of fungi in diabetic foot infections data are few and mostly conflicting. PMID:22982694

    For the last several years, third and fourth year medical students rotating on the rheumatology/immunology service at the University of North Carolina School of Medicine have been using a laptop computer as a teaching adjunct to their formal training in rheumatology. The laptop contains diagnostic programs, reference management and clinical note generation facilities, remote medline access, and most recently, multimedia case simulations. These simulations have been created by the use of a case authoring and simulation system which is presented in this demonstration. The program is divided into simulator and designer modules and uses graphics and sound to portray such data as physical examination findings, blood smears, radiographs, heart sounds, etc. The simulator module includes diagnostic sections with feedback to the student as well as robust patient management trees with an occasional circuitous route for patient outcome. The student receives a numerical score based on deviations from the correct path and optimal cost as designated by the case designer. The system simulates complete management of a patient from the first encounter until treatment is complete. During each encounter, a student obtains the patient's history, physical examination findings, orders tests and reviews their results, makes a differential diagnosis, and treats the patient. The patient's progress and further treatment options at any time are dependent on the treatment option selected by the student at an earlier stage. Students are given the costs of ancillary tests and hospitalization before they order them. Words or phrases can be marked as hypertext and the student can get more information about the marked words by a mouse click. The designer interface of the program creates the clinical case by prompts and requests for information from the designer who needs no programming skills. The designer is almost always an expert faculty member who bases the simulated case on a real patient

    In the scope of the research projects “AquiScreen” and “MiProTherm” we investigated geothermally used groundwater systems under microbial, geochemical, mineralogical and petrological aspects. On one side an enhanced process understanding of engineered geothermal systems is mandatory to optimize plant reliability and economy, on the other side this study provides insights into the microbiology of terrestrial thermal systems. Geothermal systems located in the North German Basin and the Molasse Basin were analyzed by sampling of fluids and solid phases. The investigated sites were characterized by different temperatures, salinities and potential microbial substrates. The microbial population was monitored by the use of genetic fingerprinting techniques and PCR-cloning based on PCR-amplified 16S rRNA and dissimilatory sulfite reductase (DSR) genes. DNA-sequences of fingerprints and cloned PCR-products were compared to public databases and correlated with metabolic classes to provide information about the biogeochemical processes. In all investigated geothermal plants, covering a temperature range from 5° to 120°C, microorganisms were found. Phylogenetic gene analyses indicate a broad diversity of microorganisms adapted to the specific conditions in the engineered system. Beside characterized bacteria like Thermus scotoductus, Siderooxidans lithoautotrophicus and the archaeon Methanothermobacter thermoautotrophicus a high number of so far uncultivated microorganisms was detected. As it is known that - in addition to abiotic factors - microbes like sulfate-reducing bacteria (SRB) are involved in the processes of corrosion and scaling in plant components, we identified SRB by specific analyses of DSR genes. The SRB detected are closely related to thermotolerant and thermophilic species of Desulfotomaculum, Thermodesulfovibrio, Desulfohalobium and Thermodesulfobacterium, respectively. Overall, the detection of microbes known to be involved in biocorrosion and the

Teaching future microbiologist and employees in the food industry on the importance of hygienically satisfactory water, microbiological analyses and how to ensure good water quality and safety is highly relevant. This paper presents a complete experimental design for water analyses as a tool to teach students the methods and other key elements in microbiology, including food safety, environmental dissemination and survival of microorganisms, laboratory practices, water legislation and critical evaluation of results. All results from the last 10 classes (2006-2015) in a university course on seafood microbiology have been compiled and are presented here. Questionnaires used with former students reveal that the laboratory course is highly appreciated, and that many students remember important aspects of the water analyses, even after several years. The questionnaire results were consistent with our perception that some students find calculation of dilutions difficult to comprehend. PMID:26337153
