Multifrequency Catalogue of Blazars (3rd Edition)  

NASA Astrophysics Data System (ADS)

The 3rd Edition of the Multifrequency Catalogue of Blazars is one of the most complete list of Active Galactic Nuclei whose emission properties are recognised as typical of blazars. It includes the list of sources and an essential compilation of multifrequency data from radio to gamma rays. This catalogue of blazars was initially assembled with the aim of providing a useful tool for the identification of the counterparts of the many gamma-ray sources detected by Fermi-GST, and it was actually used by the Fermi-LAT team for the preparation of the 1 LAC and 2 LAC catalogues. However, blazars are important bservational targets for a number of present and future space missions and ground-based observatories. The source list for the entire sky is available online at the ASDC web site (http://www.asdc.asi.it/bzcat/) where it is frequently updated to add new blazars and to improve the database.

Designing a 3rd generation, authenticatable attribute measurement system  

SciTech Connect

Attribute measurement systems (AMS) are designed to measure potentially sensitive items containing Special Nuclear Materials to determine if the items possess attributes which fall within an agreed-upon range. Such systems could be used in a treaty to inspect and verify the identity of items in storage without revealing any sensitive information associated with the item. An AMS needs to satisfy two constraints: the host party needs to be sure that none of their sensitive information is released, while the inspecting party wants to have confidence that the limited amount of information they see accurately reflects the properties of the item being measured. The former involves 'certifying' the system and the latter 'authenticating' it. Previous work into designing and building AMS systems have focused more on the questions of certifiability than on the questions of authentication - although a few approaches have been investigated. The next step is to build a 3rd generation AMS which (1) makes the appropriate measurements, (2) can be certified, and (3) can be authenticated (the three generations). This paper will discuss the ideas, options, and process of producing a design for a 3rd generation AMS.

The objective of this program is to model, validate, and predict the precipitation microstructure evolution, using PrecipiCalc (QuesTek Innovations LLC) software, for 3rd generation Ni-based gas turbine disc superalloys during processing and service, with a set of logical and consistent experiments and characterizations. Furthermore, within this program, the originally research-oriented microstructure simulation tool will be further improved and implemented to be a useful and user-friendly engineering tool. In this report, the key accomplishment achieved during the second year (2008) of the program is summarized. The activities of this year include final selection of multicomponent thermodynamics and mobility databases, precipitate surface energy determination from nucleation experiment, multiscale comparison of predicted versus measured intragrain precipitation microstructure in quench samples showing good agreement, isothermal coarsening experiment and interaction of grain boundary and intergrain precipitates, primary microstructure of subsolvus treatment, and finally the software implementation plan for the third year of the project. In the following year, the calibrated models and simulation tools will be validated against an independently developed experimental data set, with actual disc heat treatment process conditions. Furthermore, software integration and implementation will be developed to provide material engineers valuable information in order to optimize the processing of the 3rd generation gas turbine disc alloys.

3rd grade English language learners making sense of sound  

NSDL National Science Digital Library

Despite the extensive body of research that supports scientific inquiry and argumentation as cornerstones of physics learning, these strategies continue to be virtually absent in most classrooms, especially those that involve students who are learning English as a second language. This study presents results from an investigation of 3rd grade studentsâ discourse about how length and tension affect the sound produced by a string. These students came from a variety of language backgrounds, and all were learning English as a second language. Our results demonstrate varying levels, and uses, of experiential, imaginative, and mechanistic reasoning strategies. Using specific examples from studentsâ discourse, we will demonstrate some of the productive aspects of working within multiple language frameworks for making sense of physics. Conjectures will be made about how to utilize physics as a context for English Language Learners to further conceptual understanding, while developing their competence in the English language.

Ethical advertising in dentistry.  

PubMed

Advertising in dentistry has steadily increased since the 1970s to become a leading choice of many dentists to promote their practices. The manner in which advertising progresses within the profession affects all dentists and how patients perceive dentistry as a profession. This paper presents ethical concepts that should be followed when dentists are pursuing practice promotion through advertising. It also raises questions that, hopefully, will increase attention and discussion on dental advertising. The paper concludes that ethical advertising is easily achieved by promoting patient education while not placing the dentist's self-interests ahead of the patient's. With this approach, dentistry may continue to be one of the most trusted professions. PMID:19537484

Development of the 3rd Generation ECR ion source  

SciTech Connect

The LBNL 3rd Generation ECR ion source has progressed from a concept to the fabrication of a full scale prototype superconducting magnet structure. This new ECR ion source will combine the recent ECR ion source techniques that significantly enhance the production of high charge state ions. The design includes a plasma chamber made from aluminum to provide additional cold electrons, three separate microwave feeds to allow multiple-frequency plasma heating (at 10, 14 and 18 GHz or at 6, 10 and 14 GHz) and very high magnetic mirror fields. The design calls for mirror fields of 4 T at injection and 3 T at extraction and for a radial field strength at the wall of 2.4 T. The prototype superconducting magnet structure which consists of three solenoid coils and six race track coils with iron poles forming the sextupole has been tested in a vertical dewar. After training, the sextupole magnet reached 105% of its design current with the solenoids off. With the solenoids operating at approximately 70% of their full design field, the sextuple coils operated at 95% of the design value which corresponds to a sextupole field strength at the plasma wall of more than 2.1 T.

Design of the 3rd generation ECR ion source  

SciTech Connect

Development of the 3rd Generation ECR ion source has progressed from a concept described in the last ECR Ion Source Workshop to the fabrication of a full scale prototype superconducting magnet structure. The prototype consists of three solenoid coils and six race track coils with iron poles forming the sextupole. The design calls for mirror fields of 4 T at injection and 3 T at extraction and for a radial field strength at the wall of 2.4 T. The prototype magnet will be tested this spring in an existing vertical cryostat to determine its operating characteristics including maximum operating values, training characteristics and to study the interaction between the solenoid and sextupole coils. Design of the ECR plasma chamber includes aluminum walls to provide an enhanced source of cold electrons, up to three separate microwave feeds to allow simultaneous heating of the plasma electrons at 10, 14 and 18 GHz or at 6, 10 and 14 GHz. Water cooling of the plasma chamber walls and the injection and extraction plates is planned so that up to 10 kW of microwave power can be used without excessive heating of the chamber components. Experience with the AECR-U at LBNL shows that increasing the magnetic fields and using two frequency heating allows operation at lower neutral pressures and higher microwave power density. Both of these conditions are needed to produce very high charge states from elements with masses greater than xenon and the resulting higher energy, more intense heavy beams from the 88-Inch Cyclotron would provide new research opportunities.

Laser safety in dentistry.  

PubMed

Although many regulations and standards relating to laser safety are in effect, there continue to be an average of 35 laser injuries per year. Laser safety professionals believe that this number under-represents the actual number of injuries and that many more accidents per year occur that are not documented with federal agencies. A review of these accidents has determined that failing to wear available eye protection is one of the most frequent contributing factors to laser injuries. As the purchase and use of lasers in dentistry continues to grow, so must concern for laser safety. This article provides basic information to advance the safe use of lasers in dentistry and to help establish laser safety protocols for the dental office. PMID:19014025

Complications in implant dentistry.  

PubMed

The mainstream use of dental implants has allowed millions of patients to benefit from the predictability of dental implant therapy and, in many instances, dental implants have become the standard of care. Even though success rates in implant dentistry are well above 90 percent, complications do occur. Most complications are preventable with proper planning and execution. Others are inherent to the risks of surgery and may require intervention. The purpose of this paper is to classify the possible complications that may occur and to discuss their prevention and management. PMID:24881442

Nanotechnology and dentistry  

PubMed Central

Nanotechnology deals with the physical, chemical, and biological properties of structures and their components at nanoscale dimensions. Nanotechnology is based on the concept of creating functional structures by controlling atoms and molecules on a one-by-one basis. The use of this technology will allow many developments in the health sciences as well as in materials science, bio-technology, electronic and computer technology, aviation, and space exploration. With developments in materials science and biotechnology, nanotechnology is especially anticipated to provide advances in dentistry and innovations in oral health-related diagnostic and therapeutic methods.

Nanocharacterization in Dentistry  

PubMed Central

About 80% of US adults have some form of dental disease. There are a variety of new dental products available, ranging from implants to oral hygiene products that rely on nanoscale properties. Here, the application of AFM (Atomic Force Microscopy) and optical interferometry to a range of dentistry issues, including characterization of dental enamel, oral bacteria, biofilms and the role of surface proteins in biochemical and nanomechanical properties of bacterial adhesins, is reviewed. We also include studies of new products blocking dentine tubules to alleviate hypersensitivity; antimicrobial effects of mouthwash and characterizing nanoparticle coated dental implants. An outlook on future “nanodentistry” developments such as saliva exosomes based diagnostics, designing biocompatible, antimicrobial dental implants and personalized dental healthcare is presented.

Elements of expertise in the use of analogies in a 3rd-grade science discussion  

NSDL National Science Digital Library

Expertise in science involves the generation and use of analogies. How and when students might develop this aspect of expertise has implications for understanding how instruction might facilitate that development. We're at the beginning stages of trying to understand analogies as students use them in science classrooms. In a study of K-8 inquiry in physical science, we have seen several cases of spontaneous analogy generation at different levels of sophistication. In the case presented here, a 3rd-grader generates a particularly well-developed analogy and modifies it to reconcile his classmates' counter-arguments, allowing us to identify in these 3rd-graders specific elements of expertise in analogy use

CLINICAL ASSESSMENT OF THE 1/3rd RADIUS USING A NEW DESKTOP ULTRASONIC BONE DENSITOMETER  

PubMed Central

The objectives of this study were to evaluate the capability of a novel ultrasound device to clinically estimate bone mineral density (BMD) at the 1/3rd radius. The device rests on a desktop and is portable, and permits real-time evaluation of the radial BMD. The device measures two (2) net time delay (NTD) parameters, NTDDW and NTDCW. NTDDW is defined as the difference between the transit time of an ultrasound pulse to travel through soft-tissue, cortex and medullary cavity, and the transit time through soft tissue only of equal overall distance. NTDCW is defined as the difference between the transit time of an ultrasound pulse to travel through soft-tissue and cortex only, and the transit time through soft tissue only again of equal overall distance. The square root of the product of these two parameters is a measure of the radial BMD at the 1/3rd location as measured by dual-energy x-ray absorptiometry (DXA). A clinical IRB-approved study measured ultrasonically sixty adults at the 1/3rd radius. BMD was also measured at the same anatomical site and time using DXA. A linear regression using NTD produced a linear correlation coefficient of 0.93 (P<0.001). These results are consistent with previously reported simulation and in vitro studies. In conclusion, although x-ray methods are effective in bone mass assessment, osteoporosis remains one of the largest undiagnosed and under-diagnosed diseases in the world today. The research described here should enable significant expansion of diagnosis and monitoring of osteoporosis through a desktop device that ultrasonically assesses bone mass at the 1/3rd radius.

Using Photographs to Probe Students' Understanding of Physical Concepts: The Case of Newton's 3rd Law  

NASA Astrophysics Data System (ADS)

The starting point of the present research is the following question: since we live in an age that makes increasing use of visual representations of all sorts, is not the visual representation a learner constructs a window into his/her understanding of what is or is not being learned? Following this direction of inquiry, the present preliminary study introduces and evaluates a novel technique for pinpointing learners’ misconceptions, namely, one that has learners create and interpret their own photographs (CIP). 27 high-school students and 26 pre-service teacher trainees were asked to assume the role of textbook designers and create a display—photograph plus attached verbal explanation—which, in their opinion, best depicted Newton’s 3rd law. Subsequent analysis of the participants’ photographs yielded the following six misconception categories: 3rd law not depicted; 3rd law depicts a sequence of events; tendency to introduce irrelevant entities in explanations; the word ‘reaction’ used colloquially; tendency to restrict the application of the third law to dynamic situations; and informal explanations in which the word “force” is absent. The findings indicate that, indeed, the CIP method can be effectively employed to elicit, detect, and investigate learners’ misconceptions. The CIP method joins the growing efforts to utilize the yet relatively untapped potential of visual tools for science education purposes.

CAD/CAM in dentistry.  

PubMed

The advent of computers and interactive computer graphics laid the groundwork for a revolution in dentistry. Dental CAD/CAM systems can at least match the quality of cast restorations. With the automation, consistency in quality is also provided. The dental CAD/CAM system can simplify the effort required to produce a restoration. With new technologies for fabrication (like milling and edm), a whole array of new materials, which were historically difficult or impossible to manipulate, suddenly become viable possibilities. When used in the dental office, many of the systems eliminate the need for impressions and can produce a restoration while the patient waits. A dental revolution is underway, providing exciting possibilities for restorative dentistry. PMID:1819962

Restorative Dentistry and Research: a Contradiction?  

Microsoft Academic Search

he emergence of dentistry as an academic discipline at the end of the 19th century was closely associated with 'restorative dental sciences' such as Operative Dentistry and Prosthodontics. The foundation of a predictable and successful treatment of caries and the replacement of missing teeth based on scientific evidence were established in this early phase.

Malaria and Fetal Growth Alterations in the 3rd Trimester of Pregnancy: A Longitudinal Ultrasound Study  

PubMed Central

Background Pregnancy associated malaria is associated with decreased birth weight, but in-utero evaluation of fetal growth alterations is rarely performed. The objective of this study was to investigate malaria induced changes in fetal growth during the 3rd trimester using trans-abdominal ultrasound. Methods An observational study of 876 pregnant women (398 primi- and secundigravidae and 478 multigravidae) was conducted in Tanzania. Fetal growth was monitored with ultrasound and screening for malaria was performed regularly. Birth weight and fetal weight were converted to z-scores, and fetal growth evaluated as fetal weight gain from the 26th week of pregnancy. Results Malaria infection only affected birth weight and fetal growth among primi- and secundigravid women. Forty-eight of the 398 primi- and secundigravid women had malaria during pregnancy causing a reduction in the newborns z-score of ?0.50 (95% CI: ?0.86, ?0.13, P?=?0.008, multiple linear regression). Fifty-eight percent (28/48) of the primi- and secundigravidae had malaria in the first half of pregnancy, but an effect on fetal growth was observed in the 3rd trimester with an OR of 4.89 for the fetal growth rate belonging to the lowest 25% in the population (95%CI: 2.03–11.79, P<0.001, multiple logistic regression). At an individual level, among the primi- and secundigravidae, 27% experienced alterations of fetal growth immediately after exposure but only for a short interval, 27% only late in pregnancy, 16.2% persistently from exposure until the end of pregnancy, and 29.7% had no alterations of fetal growth. Conclusions The effect of malaria infections was observed during the 3rd trimester, despite infections occurring much earlier in pregnancy, and different mechanisms might operate leading to different patterns of growth alterations. This study highlights the need for protection against malaria throughout pregnancy and the recognition that observed changes in fetal growth might be a consequence of an infection much earlier in pregnancy.

Defining a new vision for the retinoblastoma gene: report from the 3rd International Rb Meeting  

PubMed Central

The retinoblastoma tumor suppressor (Rb) pathway is mutated in most, if not all human tumors. In the G0/G1 phase, Rb and its family members p107 and p130 inhibit the E2F family of transcription factors. In response to mitogenic signals, Cyclin-dependent kinases (CDKs) phosphorylate Rb family members, which results in the disruption of complexes between Rb and E2F family members and in the transcription of genes essential for S phase progression. Beyond this role in early cell cycle decisions, Rb family members regulate DNA replication and mitosis, chromatin structure, metabolism, cellular differentiation, and cell death. While the RB pathway has been extensively studied in the past three decades, new investigations continue to provide novel insights into basic mechanisms of cancer development and, beyond cancer, help better understand fundamental cellular processes, from plants to mammals. This meeting report summarizes research presented at the recently held 3rd International Rb Meeting.

Meeting report-3rd Neuroblastoma Research Symposium, Liverpool, 6-7th November, 2013.  

PubMed

Neuroblastoma is an embryonal malignancy of the developing neural crest. Despite improvements in treatment, prognoses remain dire for patients with high-risk disease. Interest in this enigmatic cancer has led to a rapidly changing research landscape and we report on the recent advances in four themes that were discussed at the 3rd Neuroblastoma Research Symposium: (1) The epigenetic signature of neuroblastoma and the epigenetic control of tumour development, (2) novel approaches to targeting MYCN, (3) valuable in vivo modelling and (4) improving differentiation therapies based on a knowledge of normal sympathetic neuron development. Through lively discussion, the development of combined therapies with synergistic effects for which we have a good mechanistic understanding emerged as offering greatest promise. Drug synergies enhance efficacy but also specificity, the latter crucial for reducing long-term side effects in young children. Pediatr Blood Cancer 2014;61:1711-1713. © 2014 Wiley Periodicals, Inc.

Microscope-assisted precision dentistry.  

PubMed

To enhance their vision for both clinical and laboratory procedures, an increasing number of dental practitioners are introducing magnification into their practices. Most are using either simple or compound loupes mounted on glasses frames. And although magnification is not new to dentistry, it is a trend that is gaining a broader acceptance among both seasoned practitioners and recent graduates. Many dental schools are allowing their students to use loupes on a discretionary basis, so the notion that magnification is reserved only to compensate for deteriorating vision is rapidly disappearing. Dental professionals have also begun to recognize that the quantity and quality of light in the working field is just as important as magnification. Headlamps with focused, color-correct light sources in combination with loupes are becoming popular. It is highly unlikely that a practitioner using loupes would relinquish them and return to practicing without magnification. The newest addition to the vision enhancement arena in dentistry is the operating microscope. In some medical subspecialties--such as otolaryngology, ophthalmology, plastic surgery, and neurosurgery--extensive microsurgical training is required to perform procedures at acceptable standards of precision. In 1998, the American Association of Endodontists (AAE) elected to mandate that all endodontic postgraduate students demonstrate proficiency using an operating microscope before they receive their certificates. Microscope use has also been reported in periodontics. For several decades, many dental laboratory technicians have used stereomicroscopes for trimming dies, refining castings, and performing other procedures that require a high degree of precision. However, according to microscope manufacturers, most current instrument sales are to general practitioners, who are not limiting the use of their microscopes to endodontic therapy--they are using them for a wide variety of procedures. Microscopes have the potential to enhance a dental practitioner's vision to unprecedented levels, but there are some practical questions that need to be addressed. What kind of visual acuity do dentists really need to perform high-quality dentistry? If a dentist wants to improve his or her vision, do loupes provide an adequate level of magnification? Is using a microscope too complicated for restorative and prosthodontic procedures, and how long does it take to become proficient with a microscope? These are some of the questions I posed to two outstanding dentists who have had extensive clinical experience using surgical microscopes. I also share my own experience with a microscope.

Role of Triphala in dentistry  

PubMed Central

Ayurveda is considered as the “science of life,” because the ancient Indian system of health care focused views of man and his illness. India has an age-old heritage of traditional herbal medicine. Conventional drugs usually provide effective antibiotic therapy for bacterial infections, but there is an increasing problem of antibiotic resistance and a continuing need for new solutions. Hence, now herbal drugs are being preferred to synthetic antibiotics. ‘Triphala’ is a well-known powdered preparation in the Indian system of medicine (ISM). It consists of equal parts of the Emblica officinalis, Terminalia chebula, and Terminalia belerica. Currently, Triphala is being extensively researched for its various therapeutic effects including its anti-caries, antioxidant, anti-collagenase, and anti-microbial activities. The present review will focus on the comprehensive appraisal of Triphala and its several applications in dentistry.

Optimizing human factors in dentistry  

PubMed Central

Occupational health hazards among dental professionals are on a continuous rise and they have a significant negative overall impact on daily life. This review is intended to provide the information regarding risk factors and to highlight the prevention strategies for optimizing human factors in dentistry. Risk factors among dentists are multifactorial, which can be categorized into biomechanical and psychosocial. To achieve a realistic target of safety and health at work, prevention is clearly the best approach; therefore, musculoskeletal disorders can be reduced through proper positioning of dental worker and patient, regular rest breaks, general good health, using ergonomic equipment, and exercises designed to counteract the particular risk factors for the dental occupation. However, substantial evidences are still required to elucidate the potential risk factors and to formulate effective prevention programs.

Unethical aspects of homeopathic dentistry.  

PubMed

In the last year there has been a great deal of public debate about homeopathy, the system of alternative medicine whose main principles are that like cures like and that potency increases relative to dilution. The House of Commons Select Committee on Science and Technology concluded in November 2009 that there is no evidence base for homeopathy, and agreed with some academic commentators that homeopathy should not be funded by the NHS. While homeopathic doctors and hospitals are quite commonplace, some might be surprised to learn that there are also many homeopathic dentists practising in the UK. This paper examines the statements made by several organisations on behalf of homeopathic dentistry and suggests that they are not entirely ethical and may be in breach of various professional guidelines.

The electronic journal for dentistry.  

PubMed

Electronic publishing is expanding very rapidly and will soon substitute in part for the traditional role of paper and printing in accessing information and in its library storage. This change is occurring now for medicine and engineering. For dentistry the compact disc (CD-ROM) would have advantages over tape or on-line computer systems; one or two discs a year could hold all current dental journal and textbook literature. The setting of standards is the key to the successful introduction of this technology through production and playback systems. Indexing, retrieval and hardware are considered as well as copyright problems. The profession has the chance to guide the introduction of this publishing system in preference to it being fragmented between multiple publishers and thereby becoming costly. A proposal is offered which includes the nexus of traditional printing with this new publishing form through a forum for considering standards and goals for agreement on principles. PMID:2703262

Mindfulness and professionalism in dentistry.  

PubMed

To improve the effectiveness of teaching professionalism, the authors propose introducing mindfulness practice into the dental curriculum. The qualities cultivated through mindfulness meditation practice closely resemble the global attitudes of professionalism. Professionalism and mindfulness are broad overlapping constructs with a common prosocial aim: letting go of selfish, short-sighted rewards and promoting the long-term common good. Both constructs also aim for the highest quality of life for practitioners and patients alike. Based on a selective review of the medical literature, we suggest that mindfulness practice should help improve attentiveness, self-awareness, acceptance, wisdom, and self-care in dentistry. We briefly review the role of mindfulness in higher education, as well as current attempts at Dalhousie University to integrate mindfulness into the dental and dental hygiene curricula.

MTA applications in pediatric dentistry.  

PubMed

The aim of this paper is to show and asses the clinical applications of the Mineral Trioxide Aggregate (MTA) in pediatric dentistry, either on primary teeth or on immature apex permanent teeth. We have described the primary tooth pulpotomy technique using MTA, that is characterized by a superior biocompatibility and a sealing ability that make it a more suitable compound compared to other materials in terms of result prediction on a long-term basis. We have also reported the direct capping technique using MTA on immature apex teeth; in these particular cases, MTA is undoubtedly preferable to conventional materials, especially in what its sealing characteristics concern. Furthermore, we have explained the apexogenesis clinical procedure, in which after a chamber pulpotomy on incomplete root development teeth, MTA is used in direct contact with the pulpar stump in order to save the root pulp vitality, allowing the apex and relative canal walls physiological maturation to take place. In case of necrotic teeth with immature apex, we describe the possibility of using MTA as an apical barrier making the apexification treatment faster and predictable, taking profit from its biocompatibility quality, its sealing ability and setting characteristic in humid environments. In all described applications, MTA has demonstrated to be a very versatile and extremely trustworthy material. Either literature and results obtained from the present experience, show how the use of MTA in Pediatric Dentistry, compared to commonly used materials, translates into pulp or periapical tissues being less swollen and, thus, guaranteeing a higher prediction of the therapeutic result on a short-term basis and on a long-term one.

TEC obtained from 3rd Stokes parameter for improved quality of SMOS salinity retrieval  

NASA Astrophysics Data System (ADS)

While SMOS was designed with full polarimetric capability, the 3rd Stokes parameter information has not been introduced so far in the data processing. The analysis reported in the present contribution proposes to estimate from this information the total ionospheric electron content (TEC). Indeed the Faraday effect generated by the ionospheric electrons on the path from Earth to satellite is believed to be responsible for large uncertainties in the evening half-orbits (circa 06 PM local time) when the ionospheric content is close to its diurnal maximum. It is shown that the 3rd Stokes parameter exhibits a maximal sensitivity to TEC in a restricted area located at the front of the SMOS 2D field of view. However, since the Faraday angle depends on the scalar product between line-of-sight and magnetic field vectors, a latitudinal zone is found where this sensitivity vanishes. This zone occurs around 15° N a latitude nearly invariant with longitude around the Earth. Accordingly it is possible, when carrying out the TEC estimation over a descending half-orbit, to isolate over this "blind zone" the so-called "Ocean Target Transformation" parameter, which aims at correcting for pixel dependent biases. TEC maps obtained in this way compare favorably with maps built from GPS measurements, which have been introduced so far in the SMOS processing chain as auxiliary data. The space resolution is somewhat improved, allowing a better selection of the relevant electron content in zones exhibiting large horizontal TEC gradients. In a latter step, based on the TEC maps, it becomes possible to recompute the OTT correction for those brightness temperature components to be used as input in the salinity retrieval. Then the additional information impacts the salinity retrieval both directly (as the quality of the TEC auxiliary data is improved) and indirectly (as the empirical OTT correction is no longer contaminated by spurious Faraday rotation effects). The respective contributions of both effects will be assessed and discussed. They result on the whole in a significant improvement of the SMOS retrieved salinity; this is evidenced by a large reduction of a spurious latitudinal variation which was so far considered as a bias originating in instrumental effects.

It will enable world class research by scientists from the region, reversing the brain drain. It will also build bridges between diverse societies, contributing to a culture of peace through international cooperation in science. The centerpiece is a synchrotron light source originating from BESSY I, a gift by Germany. The upgraded machine, a 2.5 GeV 3rd Generation Light Source (133m circumference, 26nm-rad emittance and 12 places for insertion devices), will provide light from infra-red to hard X-rays, offering excellent opportunities to train local scientists and attract those working abroad to return. The SESAME Council meets twice each year and presently has nine Members (Bahrain, Cyprus, Egypt, Iran, Israel, Jordan, Pakistan, Palestinian Authority, Turkey). Members have responsibility for the project and provide the annual operations budget (1.5M US dollars in 2009, expected to rise to about 5M when operation starts in 2012-13). Jordan provided the site, building, and infrastructure. A staff of 20 is installing the 0.8 GeV BESSY I injection system. The facility will have the capacity to serve 30 or more experiments operating simultaneously. See www.sesame.org.jo )

The 3^rd International Conference on Women in Physics (ICWIP), held in Seoul, Korea, in October 2008, brought together 300 participants from 57 countries, including a diverse 22-member U.S. Delegation, for a 3-day summit of stimulating discussions, thought-provoking presentations, inspirational posters, and networking. Held under the auspices of the Working Group on Women in Physics of the International Union of Pure and Applied Physics (IUPAP), this meeting built on the successes of the 1^st (Paris, 2002) and 2^nd (Rio de Janeiro, 2005) Conferences and further clarified the importance of diversifying the field of physics worldwide. Although considerable progress has been made since 2002, it was clear that the global scientific workforce is still under-utilizing a large percentage of the available female talent pool. If human society is to benefit to its fullest from various contributions that the field of physics can offer in addressing global issues of economic crisis, energy, environment, water, health, poverty, and hunger, women of all races and nationalities need to become fully included and engaged in the national and international physical community. To address these and many other issues, the ICWIP unanimously approved a five-part resolution to IUPAP recommending actions to promote the recruitment, retention, and advancement of women in physics and related fields.

Geysers Characteristics before and after Landslide of June 3-rd, 2007 (Geysers Valley, Kamchatka, Russia)  

NASA Astrophysics Data System (ADS)

Since 1990 cycling characteristics of five geysers (Maly, Bolshoy, Shel, Velican, Troynoy) were contentiously monitoring using automatic telemetric system (V A Drosnin, http://www.ch0103.emsd.iks.ru/ ). The most powerful geyser Velikan erupted steam clouds at 300 m height. 1:20 UTC June 3-rd, 2007 lower basin of the Geysers Valley was in a few minutes buried under 10 mln m3 of mud, debris, and blocks of rocks. Some indications were found, that landslide triggered by steam eruption in the upstream area of Vodopadny creek. As a result of this three famous geysers (Pervenets, Sakharny,Troynoy) located at lower elevations were sealed under 10-30 m thick caprock as well as Vodopadny hot creek, a rock dumb trap Geysernaya river and lifted water into 20 m deep lake, which flooded three famous geysers (Conus, Bolshoy and Maly) terminating their cycling activity. Nevertheless Bolshoy and Maly activity continues in a form of discharge of water circulated in the former geysers channels and a clear plume at a lake surface above exits observed. Shortly after landslide continuous monitoring of the cycling characteristics of the upper basin geysers, including Velikan and lake level, accomplished by temperature loggers - restarted. There are some indications time periods of the geysers cycling decrease.

Measurement and correction of the 3rd order resonance in the Tevatron  

SciTech Connect

At Fermilab Tevatron BPM system has been recently upgraded resulting much better accuracy of beam position measurements and improvements of data acquisition for turn-by-turn measurements. That allows one to record the beam position at each turn for 8000 turns for all BPMs (118 in each plane) with accuracy of about 10-20 {micro}m. In the last decade a harmonic analysis tool has been developed at CERN that allows relating each FFT line derived from the BPM data with a particular non-linear resonance in the machine. In fact, one can even detect the longitudinal position of the sources of these resonances. Experiments have been performed at the Tevatron in which beams have been kicked to various amplitudes to analyze the 3rd order resonance. It was possible to address this rather large resonance to some regular machine sextupoles. An alternative sextupole scheme allowed the suppression of this resonance by a good factor of 2. Lastly, the experimental data are compared with model calculations.

3rd hand smoking; heterogeneous oxidation of nicotine and secondary aerosol formation in the indoor environment  

NASA Astrophysics Data System (ADS)

Tobacco smoking is well known as a significant source of primary indoor air pollutants. However, only recently has it been recognized that the impact of Tobacco smoking may continue even after the cigarette has been extinguished (i.e., third hand smoke) due to the effect of indoor surfaces. These surfaces may affect the fate of tobacco smoke in the form of secondary reactions and pollutants, including secondary organic aerosol (SOA) formation. Fourier Transform Infrared spectrometry with Attenuated Total Reflection (FTIR-ATR) in tandem with a Scanning Mobility Particle Sizing (SMPS) system was used to monitor the ozonation of cellulose sorbed nicotine and resulting SOA formation. SOA formation began at onset of ozone introduction ([O3] = 60 ± 5 ppb) with a size distribution of dp ? 25 nm, and was determined to be a result of heterogeneous reaction (opposed to homogeneous). SOA yield from reacted surface nicotine was on the order of 10 %. Simultaneous to SOA monitoring, FTIR-ATR spectra showed surface changes in the nicotine film as the reaction progressed, revealing a pseudo first-order surface reaction rate of 0.0026 ± 0.0008 min-1. Identified surface oxidation products included: cotinine, myosmine, methylnicotinamide and nicotyrine. Surface reaction rate was found to be partially inhibited at high relative humidity. Given the toxicity of some of the identified products (e.g., cotinine has shown potential mutagenicity and teratogenicity) and that small particles may contribute to adverse health effects, the present study indicates that exposure to 3rd hand smoke ozonation products may pose additional health risks.

Catalysis in the 3rd Dimension: How Organic Molecules May be Formed  

NASA Technical Reports Server (NTRS)

Catalysis is often little more than a word to phenomenologically describe the fact that a reaction follows a pat1 that leads to products of an unexpected kind or of unexpected yield. Low activation energy barriers for intermediates are recognized as the most likely cause why a system deviates from the thermodynamic pull towards minimizing its free energy and ends up in a metastable state. Seldom is the mechanism known. This i: particularly true for heterogeneous catalysis under hydrothermal conditions with minerals as catalysts. It is commonly assumed that catalytic action takes place across solid-fluid interfaces and that, on the atomic level, interfaces are just 2-dimensional contacts. This makes it difficult to understand, for instance, the assembly of long-chain carboxylic (fatty) acids. 3y studying single crystals that grew from a melt in the presence of H2O and CO2, we can show: (1) that numerals take up the fluid components into solid solution, (2) that some-thing happens converting them to -educedH and C, (3) that C atoms segregate into dislocations and tie C-C bonds. The products are medium-to-long chain Cn protomolecules, with some C-H attached, pre-assembled in the dislocations. Upon solvent extraction, these proto-molecules turn into carboxylic and dicarboxylic acids. This observation suggests that, in a very elementary step, catalysis under hydrothermal conditions leading to fatty acids involves the pre-assembly of Cn entities in the interface that is not 2-D but extends into the 3rd dimension, with dislocations as synthesis sites.

Clinical Computing in General Dentistry  

PubMed Central

Objective: Measure the adoption and utilization of, opinions about, and attitudes toward clinical computing among general dentists in the United States. Design: Telephone survey of a random sample of 256 general dentists in active practice in the United States. Measurements: A 39-item telephone interview measuring practice characteristics and information technology infrastructure; clinical information storage; data entry and access; attitudes toward and opinions about clinical computing (features of practice management systems, barriers, advantages, disadvantages, and potential improvements); clinical Internet use; and attitudes toward the National Health Information Infrastructure. Results: The authors successfully screened 1,039 of 1,159 randomly sampled U.S. general dentists in active practice (89.6% response rate). Two hundred fifty-six (24.6%) respondents had computers at chairside and thus were eligible for this study. The authors successfully interviewed 102 respondents (39.8%). Clinical information associated with administration and billing, such as appointments and treatment plans, was stored predominantly on the computer; other information, such as the medical history and progress notes, primarily resided on paper. Nineteen respondents, or 1.8% of all general dentists, were completely paperless. Auxiliary personnel, such as dental assistants and hygienists, entered most data. Respondents adopted clinical computing to improve office efficiency and operations, support diagnosis and treatment, and enhance patient communication and perception. Barriers included insufficient operational reliability, program limitations, a steep learning curve, cost, and infection control issues. Conclusion: Clinical computing is being increasingly adopted in general dentistry. However, future research must address usefulness and ease of use, workflow support, infection control, integration, and implementation issues.

PREFACE: 3rd International Workshop on Statistical Physics and Mathematics for Complex Systems (SPMCS 2012)  

NASA Astrophysics Data System (ADS)

The 3rd International Workshop on Statistical Physics and Mathematics for Complex Systems (SPMCS2012) was held between 25-30 August at Kazan (Volga Region) Federal University, Kazan, Russian Federation. This workshop was jointly organized by Kazan Federal University and Institut Supérieur des Matériaux et Mécaniques Avancées (ISMANS), France. The series of SPMCS workshops was created in 2008 with the aim to be an interdisciplinary incubator for the worldwide exchange of innovative ideas and information about the latest results. The first workshop was held at ISMANS, Le Mans (France) in 2008, and the third at Huazhong Normal University, Wuhan (China) in 2010. At SPMCS2012, we wished to bring together a broad community of researchers from the different branches of the rapidly developing complexity science to discuss the fundamental theoretical challenges (geometry/topology, number theory, statistical physics, dynamical systems, etc) as well as experimental and applied aspects of many practical problems (condensed matter, disordered systems, financial markets, chemistry, biology, geoscience, etc). The program of SPMCS2012 was prepared based on three categories: (i) physical and mathematical studies (quantum mechanics, generalized nonequilibrium thermodynamics, nonlinear dynamics, condensed matter physics, nanoscience); (ii) natural complex systems (physical, geophysical, chemical and biological); (iii) social, economical, political agent systems and man-made complex systems. The conference attracted 64 participants from 10 countries. There were 10 invited lectures, 12 invited talks and 28 regular oral talks in the morning and afternoon sessions. The book of Abstracts is available from the conference website (http://www.ksu.ru/conf/spmcs2012/?id=3). A round table was also held, the topic of which was 'Recent and Anticipated Future Progress in Science of Complexity', discussing a variety of questions and opinions important for the understanding of the concept of complexity itself, the behaviours of complex systems as well as for the finding of new theoretical methods. The papers submitted to this volume were carefully reviewed by referees. We are very grateful to the referees for their very efficient and thoughtful actions. A few submitted papers were unfortunately not included based on the referee reports. As a result, 34 papers are included here. We are very grateful to the members of the international advisory committee for their recommendations of speakers for SPMCS2012. We also appreciate the behind-the-scenes work of the members of the local organizing committee in preparing the conference site, web page, mail correspondence, arrangements for excursions and accommodation, handling the financial support for participants, and so on. Finally, we acknowledge the support from Kazan Federal University. Sumiyoshi Abe Alain Le Méhauté Dmitrii Tayurskii

Building monument materials during the 3rd-4rd millennium (Portugal)  

NASA Astrophysics Data System (ADS)

Dolmens are the most conspicuous remains of the populations of the 4th and first half of 3rd millennia BCE. These tombs are impressive not only for their monumentality, but also because of the socioeconomic investment they represent for those Neolithic communities, namely from the Central-South of Portugal, who built them. Although dolmens have been studied for their funerary content and typologies, an interdisciplinary approach toward the geological characterization and sourcing of stones used in these constructions has not received enough attention from researchers. With MEGAGEO project a multidisciplinary group of geologist and archaeologists intends to assess the relationship between the distribution of dolmens in Central-South Portugal, their source materials, and the geological landscape. GIS will map the information gathered and will be used to analyse these relationships. The selection of the areas, with distinctive geologies (limestone vs granite), will allow to verify if human patterns of behaviour regarding the selection of megaliths are similar or different regionally. Geologically the first target area (Freixo, Alentejo) is dominated by a small intrusion of gabbro mingled/mixed within a granodioritic intrusion both related with variscan orogeny. Granodiorite exhibit several enclaves of igneous and metamorphic nature attesting the interaction between both igneous rocks as well with enclosing gneisses. Despite Alentejo region have a reduced number of outcrops the granodiorite provides rounded to tabular metric blocks. The gabbro is very coarse grained, sometimes with a cumulate texture, and their fracturing and weathering provide very fresh tabular blocks. The five studied dolmens (Quinta do Freixo #1 to #5) are implanted in a large granodioritic intrusion, around the gabbroic rocks, within an area of approximately 9km2. The medium grained granodiorite is ubiquity in all the dolmens slabs and occasionally it can be observed features of mixing and mingling mechanisms; interpenetration of different magmas and enclaves. There were not identified slabs of gabbros in dolmens slabs. In distances less than 100m from the dolmens, it is possible to identify an outcrop with equal features (petrographic as well geometric) with those found in the slabs. These observations agrees with previous authors (e.g. Boaventura, 2000) that favours a pragmatic attitude of Neolithic populations in the search of the appropriate slabs for construction.

SESAME - A 3rd Generation Synchrotron Light Source for the Middle East  

SciTech Connect

SESAME (Synchrotron-light for Experimental Science and Applications in the Middle East) will be the Middle East's first international research center. It is a cooperative venture by the scientists and governments of the region with founding members Bahrain, Egypt, Israel, Jordan, Pakistan, Palestine Authority, and Turkey. Iran is in the process of finalizing its formal membership. Other countries (Cyprus, Morocco, and the United Arab Emirates) are also expected to join. The permanent Council of member states has full responsibility for the project. Members provide the annual operating budget. Observer countries are Germany, Greece, Italy, Kuwait, Portugal, Russian Federation, Sweden, the UK, and the US. SESAME is being developed under the umbrella of UNESCO. Jordan was selected as the building site. SESAME will offer excellent opportunities for training of Middle East scientists and attract those working abroad to consider returning. SESAME will be a 2.5GeV 3rd Generation light source (emittance 26nm-rad, circumference {approx}133m), providing excellent performance for structural molecular biology, molecular environmental science, surface and interface science, microelectromechanical devices, x-ray imaging, archaeological microanalysis, and materials characterization. It will cover a broad spectral range from the infrared to hard x-rays and will have 12 straight sections for insertion devices (average length 2.75m). The injector will be the BESSY I 0.8 GeV booster synchrotron which has been given as a gift from Germany. Four committees advise the Council and assist in developing the technical design, beam lines, user community, and scientific Program. The SESAME building, now in construction with funds and a site provided by Jordan, is scheduled for completion in late 2006 after which the BESSY I injector will be installed. First stored beam in the new 2.5 GeV ring is planned for 2009 with six initial beamlines planned. Some beamlines will be built by member countries. Additional funds to purchase components of the new ring and beamlines are being sought from the EU, the US, and other sources. SESAME has benefited greatly from offers by other light source facilities of equipment and training fellowships in both accelerator technology and applications of synchrotron radiation. Details of this, and other aspects of the training program, are given below. It is hoped that in the future fellowship offers will continue to be made by many light source laboratories to further increase the level of experience with accelerator technology and synchrotron light science in preparation for the start of operation of SESAME.

Tunnelling of the 3rd kind: A test of the effective non-locality of quantum field theory  

NASA Astrophysics Data System (ADS)

Integrating out virtual quantum fluctuations in an originally local quantum field theory results in an effective theory which is non-local. In this letter we argue that tunnelling of the 3rd kind —where particles traverse a barrier by splitting into a pair of virtual particles which recombine only after a finite distance— provides a direct test of this non-locality. We sketch a quantum-optical setup to test this effect, and investigate observable effects in a simple toy model.

Evidence of human-induced morphodynamic changes along the Campania coastal areas (southern Italy) since the 3rd-4th cent. AD  

NASA Astrophysics Data System (ADS)

Campania has always offered suitable climatic and physiographic conditions for human settlements since prehistoric times. In particular, many Graeco-Roman towns developed along its coasts starting from the 7th-6th cent. BC. In the last decade, geoarchaelogical surveys have been carried out in the archaeological excavations of Neapolis, Paestum and Elea-Velia allowing the main steps of the landscape evolution around these towns to be defined in detail. The greek town of Neapolis rose in the late 6th cent. BC [1] on a terrace overlooking a low-relief rocky coast surrounded by volcanic hills. Port activities developed in a protected bay facing the town from the 4th-2nd cent. BC up to the 4th cent. AD, as testified by the discovery of structures and shipwrecks [2, 3, 4]. Starting from the 3rd cent. AD a spit bar formed at the bay entrance causing the progressive establishment of a lagoon which was gradually filled up by alluvial inputs and completely closed in the 5th cent. AD. During the same period, episodes of increased alluvial inputs were also recorded further west along the coast, where a narrow sandy beach formed at the cliff toe. The greek town of Poseidonia, renamed Paestum by the Romans, was founded in the 540 BC on a travertine terrace facing the sandy littoral of a prograding coastal plain [5]. In front of the main town door, a coastal lagoon developed thanks to the growth of a dune ridge and was probably used for harbor activities [5]. After this period the shoreline shifted seawards, another dune ridge formed and the back-ridge depression was filled with fluvial-marshy deposits, slowly drying up. Phases of travertine deposition, which characterized the SE sector of the plain all along the Holocene, were recorded in the northern and southern quarters of the town in historical times and were connected to the abandonment of the town in the early Medieval times. The greek colony of Elea-Velia was located on top of a siliciclastic promontory where the ruins of the first archaic settlement (late 6th cent. BC) was unearthed. The Graeco-Roman town expanded downhill, exploiting the growth of a coastal plain, where occasional phases of flooding coexisted with the life of the citizens [6]. The onset of the 3rd cent. AD was characterized by phases of extreme floods which also occurred during the 4th and 5th cent. AD leading to several meters of ground-level aggradation and the burial of buildings [6, 7]. Although the three investigated sites are located in rather different morphological context, they show the evidence of a disequilibrium in the morphodynamics which started in the 3rd-4th cent. AD. The vast amount of collected data strongly suggest that this disequilibrium is a clear sign of a socio-economic decline which affected the Roman Empire during this period rather than the consequence of a climatic deterioration towards dryer conditions, for which no detailed data are available in the Mediterranean area [8]. The abandonment of the towns and their surroundings triggered increased soil erosion on the slopes suffering deforestation and in the farmlands for reduced maintenance, enhancing accumulation rates at the foothills and along coastal areas.

A global drought climatology for the 3rd edition of the World Atlas of Desertification (WAD)  

NASA Astrophysics Data System (ADS)

A new version of the World Atlas of Desertification (WAD) is being compiled in the framework of cooperation between the Joint Research Centre (JRC) of the European Commission and the United Nations Environment Programme (UNEP). This initiative aims at mapping the global land degradation and desertification, as well as introducing the reader with complex interactions of geo-physical, socio-economic, and political aspects that affect the environmental sustainability. Recurrent extreme events resulting from climate change, such as more severe droughts, combined with non-adapted land use practices can affect the resilience of ecosystems tipping them into a less productive state. Thus, to describe the effects of climatological hazards on land degradation and desertification processes, we computed a World drought climatology that will be part of the 3rd edition of the WAD and will replace and update to 2010 the results presented in the 2nd edition in 1997. This paper presents the methodology used to compute three parameters included in the WAD drought climatology, i.e. drought frequency, intensity and duration, and discusses their spatio-temporal patterns both at global and continental scales. Because drought is mainly driven and triggered by a rainfall deficit, we chose the Standardized Precipitation Index (SPI) as the drought indicator to estimate our climatological parameters. The SPI is a statistical precipitation-based drought indicator widely used in drought-related studies. We calculated the SPI on three different accumulation periods: 3 months (SPI-3), 6 months (SPI-6), and 12 months (SPI-12), in order to take into account meteorological, agricultural, and hydrological drought-related features. Each quantity has been calculated on a monthly basis using the baseline period between January 1951 and December 2010. As data input, we used the Full Data Reanalysis Version 6.0 (0.5?x0.5?) of gridded monthly precipitation provided by the Global Precipitation Climatology Center (GPCC) of the Deutscher Wetterdienst (DWD). This dataset was selected after an extensive quality check on data reliability, homogeneity, and physical consistency. We defined the drought frequency as the number of months with SPI below -1 out of all months in different periods of 10-15 years between 1951 and 2010. For the drought intensity we analyzed the drought events with at least 3 consecutive months with SPI below -1. The drought duration is defined in an operative way: a drought starts when SPI first falls below -1 and it ends when it turns back positive (i.e. >0) for at least 2 consecutive months. The results show that in the last two decades, as compared to the long-term normal conditions, the regions most affected by drought events were Congo and Central Africa, North-Eastern China, the Australian South-Eastern coast, and the Middle East. In general, an increase in duration and intensity of drought events was found for almost all the Northern Hemisphere. We also focused on some regional case studies dealing with drought events in the Mediterranean region, the Horn of Africa, and South America in the last 15 years

FOREWORD: 3rd International Workshop on New Computational Methods for Inverse Problems (NCMIP 2013)  

NASA Astrophysics Data System (ADS)

Conference logo This volume of Journal of Physics: Conference Series is dedicated to the scientific contributions presented during the 3rd International Workshop on New Computational Methods for Inverse Problems, NCMIP 2013 (http://www.farman.ens-cachan.fr/NCMIP_2013.html). This workshop took place at Ecole Normale Supérieure de Cachan, in Cachan, France, on 22 May 2013, at the initiative of Institut Farman. The prior editions of NCMIP also took place in Cachan, France, firstly within the scope of the ValueTools Conference, in May 2011 (http://www.ncmip.org/2011/), and secondly at the initiative of Institut Farman, in May 2012 (http://www.farman.ens-cachan.fr/NCMIP_2012.html). The NCMIP Workshop focused on recent advances in the resolution of inverse problems. Indeed inverse problems appear in numerous scientific areas such as geophysics, biological and medical imaging, material and structure characterization, electrical, mechanical and civil engineering, and finances. The resolution of inverse problems consists of estimating the parameters of the observed system or structure from data collected by an instrumental sensing or imaging device. Its success firstly requires the collection of relevant observation data. It also requires accurate models describing the physical interactions between the instrumental device and the observed system, as well as the intrinsic properties of the solution itself. Finally, it requires the design of robust, accurate and efficient inversion algorithms. Advanced sensor arrays and imaging devices provide high rate and high volume data; in this context, the efficient resolution of the inverse problem requires the joint development of new models and inversion methods, taking computational and implementation aspects into account. During this one-day workshop, researchers had the opportunity to bring to light and share new techniques and results in the field of inverse problems. The topics of the workshop were: algorithms and computational aspects of inversion, Bayesian estimation, kernel methods, learning methods, convex optimization, free discontinuity problems, metamodels, proper orthogonal decomposition, reduced models for the inversion, non-linear inverse scattering, image reconstruction and restoration, and applications (bio-medical imaging, non-destructive evaluation...). NCMIP 2013 was a one-day workshop held in May 2013 which attracted around 60 attendees. Each of the submitted papers has been reviewed by three reviewers. Among the accepted papers, there are seven oral presentations, five posters and one invited poster (On a deconvolution challenge presented by C Vonesch from EPFL, Switzerland). In addition, three international speakers were invited to present a longer talk. The workshop was supported by Institut Farman (ENS Cachan, CNRS) and endorsed by the following French research networks (GDR ISIS, GDR Ondes, GDR MOA, GDR MSPC).

These conference proceedings contain the written papers of the contributions presented at the 3rd International Conference on Theory, Modelling and Computational Methods for Semiconductor materials and nanostructures. The conference was held at the School of Electronic and Electrical Engineering, University of Leeds, Leeds, UK on 18-20 January 2012. The previous conferences in this series took place in 2010 at St William's College, York and in 2008 at the University of Manchester, UK. The development of high-speed computer architectures is finally allowing the routine use of accurate methods for calculating the structural, thermodynamic, vibrational, optical and electronic properties of semiconductors and their hetero- and nano-structures. The scope of this conference embraces modelling, theory and the use of sophisticated computational tools in semiconductor science and technology, where there is substantial potential for time-saving in R&D. Theoretical approaches represented in this meeting included: Density Functional Theory, Tight Binding, Semiempirical Pseudopotential Methods, Effective Mass Models, Empirical Potential Methods and Multiscale Approaches. Topics included, but were not limited to: Optical and Transport Properties of Quantum Nanostructures including Colloids and Nanotubes, Plasmonics, Magnetic Semiconductors, Graphene, Lasers, Photonic Structures, Photovoltaic and Electronic Devices. This workshop ran for three days, with the objective of bringing together UK and international leading experts in the theoretical modelling of Group IV, III-V and II-VI semiconductors, as well as students, postdocs and early-career researchers. The first day focused on providing an introduction and overview of this vast field, aimed particularly at students, with several lectures given by recognised experts in various theoretical approaches. The following two days showcased some of the best theoretical research carried out in the UK in this field, with several contributions also from representatives of renowned theoretical groups from many European countries (Spain, France, Ireland, Germany, Italy, Poland, Denmark, Sweden, Serbia, Greece, etc.), as well as Asia (India) and Africa (Algeria, Tunisia and South Africa).

Influence of solar eclipse of November 3rd, 2013 on the total ozone column over Badajoz, Spain  

NASA Astrophysics Data System (ADS)

The hybrid eclipse of November 3rd, 2013 was observed as partial with a magnitude equal to 0.126 from Badajoz (38° 53? N, 6° 58? W). The evolution of the total ozone column (TOC) values for 4 h was monitored using a Solar Light Microtops-II manual sun-photometer. Before the eclipse, TOC remained invariable ~280 Dobson Units (DU) for one hour and a half. Once the eclipse was started, a clear decrease in TOC occurred. After the eclipse maximum (with TOC=273 DU), a rapid TOC recovery was observed. When the eclipse was over, TOC came back to values ~280 DU.

Analysis and design of a 3rd order velocity-controlled closed-loop for MEMS vibratory gyroscopes.  

PubMed

The time-average method currently available is limited to analyzing the specific performance of the automatic gain control-proportional and integral (AGC-PI) based velocity-controlled closed-loop in a micro-electro-mechanical systems (MEMS) vibratory gyroscope, since it is hard to solve nonlinear functions in the time domain when the control loop reaches to 3rd order. In this paper, we propose a linearization design approach to overcome this limitation by establishing a 3rd order linear model of the control loop and transferring the analysis to the frequency domain. Order reduction is applied on the built linear model's transfer function by constructing a zero-pole doublet, and therefore mathematical expression of each control loop's performance specification is obtained. Then an optimization methodology is summarized, which reveals that a robust, stable and swift control loop can be achieved by carefully selecting the system parameters following a priority order. Closed-loop drive circuits are designed and implemented using 0.35 ?m complementary metal oxide semiconductor (CMOS) process, and experiments carried out on a gyroscope prototype verify the optimization methodology that an optimized stability of the control loop can be achieved by constructing the zero-pole doublet, and disturbance rejection capability (D.R.C) of the control loop can be improved by increasing the integral term.

Dependence of cosmic ray solar daily variation (1st, 2nd and 3rd) on heliomagnetic polarity reversals  

NASA Astrophysics Data System (ADS)

Using 696 station-years of neutron monitor data during the period of 1964-1983 as well as data from muon telescopes at surface and underground stations, a long term variation of cosmic ray solar daily variations (1st, 2nd and 3rd) has been analyzed to study its dependence on the heliomagnetic polarity reversals. It is found that the 1st, 2nd and 3rd harmonic variations show respective counter-clockwise phase shifts on the harmonic dial for the transition from the negative to the positive polarity state. The polarity state is defined as 'positive' ('negative') when the interplanetary magnetic field (IMF) is away (toward) in the Northern Hemisphere and toward (away) in the Southern Hemisphere. It is demonstrated that these phase shifts cannot be explained by one-dimensional diffusion of the pitch angle distribution along the IMF-axis, such as the one presented by Bieber and Pomerantz (1983), but can be explained by three-dimensional treatment of the cosmic ray diffusion-convection in space, developed by Munakata and Nagashima (1986) in considering the drift effect in the heliosphere which was pointed out by Jokipii et al. (1977). According to the theory, the rigidity dependence of the observed phase shift of the 2nd harmonic variation suggests that the power exponent of the rigidity spectrum of the cosmic ray mean free path is less than unity, at least in a rigidity region of about one to several tens of GV.

Characterization of a 3rd Generation Lentiviral Vector Pseudotyped With Nipah Virus Envelope Proteins For Endothelial Cell Transduction  

PubMed Central

Lentiviruses are becoming progressively more popular as gene therapy vectors due to their ability to integrate into quiescent cells and recent clinical trial successes. Directing these vectors to specific cell types and limiting off-target transduction in vivo remains a challenge. Replacing the viral envelope proteins responsible for cellular binding, or pseudotyping, remains a common method to improve lentiviral targeting. Here, we describe the development of a high titer, 3rd generation lentiviral vector pseudotyped with Nipah virus fusion protein (NiV-F) and attachment protein (NiV-G). Critical to high titers was truncation of the cytoplasmic domains of both NiV-F and NiV-G. As known targets of wild-type Nipah virus, primary endothelial cells are shown to be effectively transduced by the Nipah pseudotype. In contrast, human CD34+ hematopoietic progenitors were not significantly transduced. Additionally, the Nipah pseudotype has increased stability in human serum compared to VSV pseudotyped lentivirus. These findings suggest that the use of Nipah virus envelope proteins in 3rd generation lentiviral vectors would be a valuable tool for gene delivery targeted to endothelial cells.

Dentistry students' perceptions of learning management systems.  

PubMed

This paper reports an exploratory survey study about students' perceptions of learning management systems (LMS) at the Faculty of Dentistry, University of Sydney. Two hundred and fifty-four students enrolled in the Bachelor of Dentistry and the Bachelor of Oral Health programmes participated in an online survey aimed at exploring their beliefs and attitudes as well as their preferences for eLearning tools. Results indicated a strong preference of students for using LMSs as resource repositories rather than for higher-order learning activities such as online discussion forums. This finding holds importance for consideration of the development of the educational resources modalities that support development of essential graduate attributes such as information literacy and collaborative learning.

Ozone therapy in dentistry: A strategic review  

PubMed Central

The oral cavity appears as an open ecosystem, with a dynamic balance between the entrance of microorganisms, colonization modalities, and host defenses aimed to their removal: To avoid elimination, bacteria need to adhere to either hard dental surfaces or epithelial surfaces. The oral biofilm formation and development, and the inside selection of specific microorganisms have been correlated with the most common oral pathologies, such as dental caries, periodontal disease, and peri-implantitis. The mechanical removal of the biofilm and adjunctive use of antibiotic disinfectants or various antibiotics have been the conventional methods for periodontal therapy. Ozone (O3) is a triatomic molecule, consisting of three oxygen atoms, and its application in medicine and dentistry has been indicated for the treatment of 260 different pathologies. The ozone therapy has been more beneficial than present conventional therapeutic modalities that follow a minimally invasive and conservative application to dental treatment. The exposition of molecular mechanisms of ozone further benefits practical function in dentistry.

Geriatric dentistry--meet the need.  

PubMed

Geriatric dentistry or gerodontics is the delivery of dental care to older adults involving the diagnosis, prevention, and treatment of problems associated with normal ageing and age-related diseases as part of an inter-disciplinary team with other health care professionals. Geriatric health is an ignored and under-explored area worldwide. Oral health reflects overall well being for the elderly population. Conversely, elderly patients are more predisposed to oral conditions due to age-related systemic diseases and functional changes. The major barriers to practising geriatric dentistry are the lack of trained faculty members, a crowded curriculum and monetary concerns. For successful treatment, the practitioner must adopt a humanitarian approach and develop a better understanding of the feelings and attitudes of the elderly. Prevention and early intervention strategies must be formulated to reduce the risk of oral diseases in this population. In future, dental professionals must have a proper understanding of the magnitude of the services to be provided to the elderly. This could only be realised through an education programme in geriatric dentistry, which should be started without further delay. This article hence sets out the objectives, needs, present scenario, strategies and types of dental treatment required by the elderly population. PMID:22612827

Mesenchymal dental stem cells in regenerative dentistry  

PubMed Central

In the last decade, tissue engineering is a field that has been suffering an enormous expansion in the regenerative medicine and dentistry. The use of cells as mesenchymal dental stem cells of easy access for dentist and oral surgeon, immunosuppressive properties, high proliferation and capacity to differentiate into odontoblasts, cementoblasts, osteoblasts and other cells implicated in the teeth, suppose a good perspective of future in the clinical dentistry. However, is necessary advance in the known of growth factors and signalling molecules implicated in tooth development and regeneration of different structures of teeth. Furthermore, these cells need a fabulous scaffold that facility their integration, differentiation, matrix synthesis and promote multiple specific interactions between cells. In this review, we give a brief description of tooth development and anatomy, definition and classification of stem cells, with special attention of mesenchymal stem cells, commonly used in the cellular therapy for their trasdifferentiation ability, non ethical problems and acceptable results in preliminary clinical trials. In terms of tissue engineering, we provide an overview of different types of mesenchymal stem cells that have been isolated from teeth, including dental pulp stem cells (DPSCs), stem cells from human exfoliated deciduous teeth (SHEDs), periodontal ligament stem cells (PDLSCs), dental follicle progenitor stem cells (DFPCs), and stem cells from apical papilla (SCAPs), growth factors implicated in regeneration teeth and types of scaffolds for dental tissue regeneration. Key words:Dental stem cells, regenerative dentistry, mesenchymal stem cells, tissue engineering, stem cells.

PREFACE: EDS2010 Preface  

NASA Astrophysics Data System (ADS)

The biennial international conference on Extended Defects in Semiconductors started in 1978 with a meeting in Hünfeld, Germany. Subsequent meetings rotated between Poland, France, Great Britain, Germany, Russia and Italy, culminating in EDS2004 in Chernogolovka, EDS2006 in Halle and EDS2008 in Poitiers. EDS2010 was held at the University of Sussex at Brighton, UK from September 19th to 24th. An extension of the tabulation of this history, which first appeared on the EDS2006 website, is given in the attached PDF. It is with sadness that we note one of the founders of the series, Prof. Dr Helmut Alexander, passed away on 3 December 2009 and we were proud to dedicate EDS2010 to his memory. It has become a tradition to make an award in his name, and this year it was made to Ivan Isacov for his poster "Electrical levels of dislocation networks in p- and n-type silicon". A short and warm celebration of Prof. Dr Alexander's life by his friends and colleagues, Prof. Drs Helmut Gottschalk, Eicke Weber and Wolfgang Schröter, is included in this volume. The conference was a forum for the state-of-the-art of investigation and modelling of extended defects in semiconductors. Scientists from universities, research institutes and industry made contributions to a deeper understanding of extended defects, their interaction with point defects and their role in the development of semiconductor technology. The remit of the conference included extended defects, nanostructures, nanoparticles, quantum dots and interfaces within semiconducting materials ranging from narrow to wide band gaps, including graphene-derived materials and diamond. Scientific interests range from defect geometry, electronic structure, dynamics, spectroscopy, microscopy, reactions and chemistry to introduction mechanisms, such as implantation and strained layers and the operation of devices such as integrated circuits, heterostructures, and solar cells. The organisers were confronted with a long period between the afternoon outing to Arundel Castle and dinner in the evening at Wiston House, a mansion of Tudor origin near Steyning, West Sussex. So a short audience-participation seminar was held in the conference room of the manor, covering the history of dislocations and the history of the conference series. We were also able to extend the appreciation of the life of Prof. Yuri Ossipyan (15 Feb 1931 - 10 Sep 2008) briefly given at EDS2008. EDS2010 continued the drive into graphene-based materials with a session devoted to them, and it gave immense pleasure to many of us who were his former students to dedicate a session to the work of Professor R Jones. We are grateful to his present and former co-workers who came and presented an impressive perspective on their work with him and a vision of a vigorous future for him in his retirement and for AIMPRO, the current Density Functional Theory code that derives from the one he established with his former student, Dr Patrick Briddon. For EDS2010 we made two minor modifications to the appearance of the conference: a central webpage www.eds-conferences.org, ably managed by our webmaster, Dr Gemma Haffenden, and a Facebook page, "EDS conference series", which Dr Amy Gandy runs enthusiastically. Amongst other things the conference photographs appear here. "I like this". In fact, currently 22 FB-ers "like this" and I am sure it will grow. Finally, it is a pleasure to acknowledge the significant contributions of Co-Chair, Prof. Marek Skowronski, Conference Manager, Dr Christopher Latham, and the editors of this volume, Drs Jon Goss and Chris Ewels, who in turn wish to thank Dr Alexis Vlandas for his help proof reading the articles. We all wish the best of luck to Prof. Philomela Khomninou and her team in the organisation of EDS2012.

While countries varies significantly in the financing of dental care, they are much more alike in the delivery of dentistry. Dental care is principally provided in dental offices and clinics that are independent business entities whose business leaders are most often the dentists themselves. However society expects from dentists a level of professionalism (i.e. habitually acting ethically, both in terms of competence and conduct) in contrast to the methods and motivations of the marketplace. This is why the single most important challenge of dental professional ethics continues to be giving proper priority to patients' well being and building ethically correct decision-making relationships with patients while, at the same time, trying to maintain a successful business operation. If we look into dentistry's future, the centrality of this aspect of professional ethics is not likely to change, although the ways in which dentists might violate this trust will probably multiple as funding mechanisms become increasingly complex. It is important that dentists reflect with fresh eyes on their ethical commitments. One challenge is the increased availability of oral health information to the public and the fact that so many people are uncritical of the accuracy of information in the media and on the web. A second is the increase in the amount of health care advertising in many societies. A third is the growth of aesthetic dentistry that differs from standard oral health care in important and ethically significant ways. The fourth is insurance that frequently complicates the explanation of a patient's treatment alternatives and often brings a third party into the treatment decision relationship. The ethical challenges of each of these factors will be considered and ultimately tying it to the central theme of dental professionalism. PMID:23221268

Position paper on digital communication in dentistry.  

PubMed

Digital communication offers advantages and challenges to dental practice. As dentistry becomes comfortable with this technology, it is essential that commercial and other values not be accepted on a par with professional ones and that the traditional dentist-patient relationship not be compromised by inserting third parties that introduce nonprofessional standards. The Officers and Regents of the American College of Dentist have prepared this background and position paper as a guide to the ethical use of digital communication in dental practice. PMID:23654160

Forensic dentistry in a terrorist world.  

PubMed

While body identification by dental means has not changed substantially since 9/11, or even since the bombing of the Murrah Federal Building in Oklahoma City in 1995, the conditions and potential risks of a bioterrorism action to the dental personnel is new. The purpose of this article is to review general forensic dentistry disaster responses and to address the impact a bioterrorism action might have on primary, secondary and tertiary dental responders. It will also examine the triage role that dental offices might play in the event of such a disaster. PMID:16013679

The changing face of dentistry: nanotechnology  

PubMed Central

The human body comprises molecules; hence, the availability of molecular nanotechnology will permit dramatic progress to address medical problems and will use molecular knowledge to maintain and improve human health at the molecular scale. Nanomedicine could develop devices that are able to work inside the human body in order to identify the early presence of a disease, and to identify and quantify toxic molecules and tumor cells, for example. Nanodentistry will make possible the maintenance of comprehensive oral health by employing nanomaterials, including tissue engineering and, ultimately, dental nanorobots. This review is an attempt to highlight the possible applications of nanotechnology and the use of nanomaterials in dentistry.

Biosmart materials: breaking new ground in dentistry.  

PubMed

By definition and general agreement, smart materials are materials that have properties which may be altered in a controlled fashion by stimuli, such as stress, temperature, moisture, pH, and electric or magnetic fields. There are numerous types of smart materials, some of which are already common. Examples include piezoelectric materials, which produce a voltage when stress is applied or vice versa, shape memory alloys or shape memory polymers which are thermoresponsive, and pH sensitive polymers which swell or shrink as a response to change in pH. Thus, smart materials respond to stimuli by altering one or more of their properties. Smart behaviour occurs when a material can sense some stimulus from its environment and react to it in a useful, reliable, reproducible, and usually reversible manner. These properties have a beneficial application in various fields including dentistry. Shape memory alloys, zirconia, and smartseal are examples of materials exhibiting a smart behavior in dentistry. There is a strong trend in material science to develop and apply these intelligent materials. These materials would potentially allow new and groundbreaking dental therapies with a significantly enhanced clinical outcome of treatments. PMID:24672407

Advances in operative dentistry and fixed prosthodontics.  

PubMed

The rapid developments in biomaterials has led not only to improved materials but also to the development of clinical techniques made possible by these advances. Adhesive dentistry remains one of the fastest changing fields and this will most likely continue well into the next decade. Patients' aesthetic awareness and, to some extent, concern about amalgam has produced a growing demand for posterior tooth-coloured restorations. Originally this was met by ceramo-metal crowns and subsequently by the development of posterior composite resins. Recent development of stronger ceramics and better luting have now made all-ceramic restorations possible in posterior sites. Several new techniques for cavity preparation are emerging as alternatives to the conventional handpiece while the quest for amalgam alternatives continues. As with all recent developments there are, by definition, few long-term clinical data yet available to allow a comprehensive evaluation of the relevant materials and techniques. This paper is a summary of the most significant recent advances in fixed prosthodontics and operative dentistry. PMID:11405026

Emerging trends of herbal care in dentistry.  

PubMed

Herbs are staging a comeback and herbal 'renaissance' is happening all over the globe. The herbal products, today, symbolize safety, in contrast to the synthetics that are regarded as unsafe to humans and the environment. A herb, botanically speaking, is any plant that lacks the woody tissue which is characteristic of shrubs or trees. More specifically, herbs are plants which are used medicinally or for their flavour or scent. Herbs with medicinal properties are a useful and an effective source of treatment for various disease processes. Herbal extracts have been successfully used in dentistry as tooth cleaning and antimicrobial plaque agents. The use of herbal medicines continues to expand rapidly across the world. Many people take herbal medicines or herbal products now for their health care in different national healthcare settings. Herbal extracts have been used in dentistry for reducing inflammation, as antimicrobial plaque agents, for preventing release of histamine and as antiseptics, antioxidants, antimicrobials, antifungals, antibacterials, antivirals and analgesics. They also aid in healing and are effective in controlling microbial plaque in gingivitis and periodontitis, thereby improving immunity. PMID:24086929

Mesenchymal dental stem cells in regenerative dentistry.  

PubMed

In the last decade, tissue engineering is a field that has been suffering an enormous expansion in the regenerative medicine and dentistry. The use of cells as mesenchymal dental stem cells of easy access for dentist and oral surgeon, immunosuppressive properties, high proliferation and capacity to differentiate into odontoblasts, cementoblasts, osteoblasts and other cells implicated in the teeth, suppose a good perspective of future in the clinical dentistry. However, is necessary advance in the known of growth factors and signalling molecules implicated in tooth development and regeneration of different structures of teeth. Furthermore, these cells need a fabulous scaffold that facility their integration, differentiation, matrix synthesis and promote multiple specific interactions between cells. In this review, we give a brief description of tooth development and anatomy, definition and classification of stem cells, with special attention of mesenchymal stem cells, commonly used in the cellular therapy for their trasdifferentiation ability, non ethical problems and acceptable results in preliminary clinical trials. In terms of tissue engineering, we provide an overview of different types of mesenchymal stem cells that have been isolated from teeth, including dental pulp stem cells (DPSCs), stem cells from human exfoliated deciduous teeth (SHEDs), periodontal ligament stem cells (PDLSCs), dental follicle progenitor stem cells (DFPCs), and stem cells from apical papilla (SCAPs), growth factors implicated in regeneration teeth and types of scaffolds for dental tissue regeneration.

Creating an Evidence-Based Dentistry Culture at Baylor College of Dentistry: The Winds of Change  

PubMed Central

In the early years of the new millennium, the National Institute of Dental and Craniofacial Research of the National Institutes of Health began funding Oral Health Research Education Grants using the R25 mechanism to promote the application of basic and clinical research findings to clinical training and to encourage students to pursue careers in oral health research. This report describes the impact of an R25 grant awarded to the Texas A&M Health Science Center’s Baylor College of Dentistry (BCD) on its curriculum and faculty development efforts. At BCD, the R25 grant supports a multipronged initiative that employs clinical research as a vehicle for acquainting both students and faculty with the tools of evidence-based dentistry (EBD). New coursework and experiences in all four years of the curriculum plus a variety of faculty development offerings are being used to achieve this goal. Progress on these fronts is reflected in a nascent EBD culture characterized by increasing participation and buy-in by students and faculty. The production of a new generation of dental graduates equipped with the EBD skill set as well as a growing nucleus of faculty members who can model the importance of evidence-based practice is of paramount importance for the future of dentistry.

Photobiomodulation and implants: implications for dentistry  

PubMed Central

The use of dental implants has become a mainstay of rehabilitative and restorative dentistry. With an impressive clinical success rate, there remain a few minor clinical issues with the use of implants such as peri-implant mucositis and peri-implantitis. The use of laser technology with implants has a fascinating breadth of applications, beginning from their precision manufacturing to clinical uses for surgical site preparation, reducing pain and inflammation, and promoting osseointegration and tissue regeneration. This latter aspect is the focus of this review, which outlines various studies of implants and laser therapy in animal models. The use of low level light therapy or photobiomodulation has demonstrated its efficacy in these studies. Besides more research studies to understand its molecular mechanisms, significant efforts are needed to standardize the clinical dosing and delivery protocols for laser therapy to ensure the maximal efficacy and safety of this potent clinical tool for photobiomodulation.

The role of hypnotherapy in dentistry.  

PubMed

Dental fear is a universal phenomenon justifying the increasing relevance of psychology and the behavioural sciences to dental training and clinical practice. Pharmacological sedation has been used more and more over the past two decades, in order to relieve dental anxiety and phobia and let the patient face oral surgery safely. Hypnosis is a still underused but powerful non-pharmacological tool in dentistry. It provides an effective sedation whilst maintaining patient collaboration, but it also may help patients recovering from dental anxiety and phobia as well as those with a severe gag reflex. While pharmacological sedation affords a temporary respite and helps the patient to cope with a single procedure, hypnosis can effectively allow for both an excellent sedation in a physiological way and the treatment of patients' anxiety, or substantially decrease the doses used for sedative and analgesic drugs when these are needed.

Analysis of structural and molecular events associated with adult rat optic chiasm and nerves demyelination and remyelination: possible role for 3rd ventricle proliferating cells.  

PubMed

Multiple sclerosis frequently affects the optic apparatus, particularly optic chiasm and nerves. Here, we have reported the structural and molecular characteristics of remyelination in the adult rat optic chiasm and nerves. Moreover, considering the proximity of optic chiasm and 3rd ventricle, we have tried to determine if proliferating cells residing in 3rd ventricle region are able to migrate in response to experimental demyelination of the optic chiasm. Following local demyelination by lysolecithin, remyelination pattern in longitude of optic chiasm and proximal nerves was investigated using myelin staining and marker genes expression. Furthermore, cell tracing was carried out using BrdU labeling of proliferating cells prior to gliotoxin injection. Morphometric analysis revealed that demyelination was considerable on days 7 and 14 and an incomplete remyelination occurred on day 28 post-lesion. Interestingly, myelin repair was more evident in the caudal part of chiasm, compared to rostral part and proximal optic nerves. Following chiasm and nerve demyelination, trains of BrdU+ cells were seen near the 3rd ventricle which subsequently moved to lesion site. Nestin was significantly up-regulated in 3rd ventricle surroundings. At the lesion site, Nogo-A gene expression was significantly decreased on days 7 and 14 post lesion, while Olig2, nestin, and GFAP expression was increased on day 7. The changes were then reversed by the time. Myelin repair in optic chiasm seems to be mediated by endogenous progenitors and stem cells. Adult 3rd ventricle proliferating cells may play a role in this context by mobilization into the demyelinated chiasm. PMID:21290199

HDACi: cellular effects, opportunities for restorative dentistry.  

PubMed

Acetylation of histone and non-histone proteins alters gene expression and induces a host of cellular effects. The acetylation process is homeostatically balanced by two groups of cellular enzymes, histone acetyltransferases (HATs) and histone deacetylases (HDACs). HAT activity relaxes the structure of the human chromatin, rendering it transcriptionally active, thereby increasing gene expression. In contrast, HDAC activity leads to gene silencing. The enzymatic balance can be 'tipped' by histone deacetylase inhibitors (HDACi), leading to an accumulation of acetylated proteins, which subsequently modify cellular processes including stem cell differentiation, cell cycle, apoptosis, gene expression, and angiogenesis. There is a variety of natural and synthetic HDACi available, and their pleiotropic effects have contributed to diverse clinical applications, not only in cancer but also in non-cancer areas, such as chronic inflammatory disease, bone engineering, and neurodegenerative disease. Indeed, it appears that HDACi-modulated effects may differ between 'normal' and transformed cells, particularly with regard to reactive oxygen species accumulation, apoptosis, proliferation, and cell cycle arrest. The potential beneficial effects of HDACi for health, resulting from their ability to regulate global gene expression by epigenetic modification of DNA-associated proteins, also offer potential for application within restorative dentistry, where they may promote dental tissue regeneration following pulpal damage.

Ceramics in Restorative and Prosthetic DENTISTRY1  

NASA Astrophysics Data System (ADS)

This review is intended to provide the ceramic engineer with information about the history and current use of ceramics in dentistry, contemporary research topics, and potential research agenda. Background material includes intra-oral design considerations, descriptions of ceramic dental components, and the origin, composition, and microstructure of current dental ceramics. Attention is paid to efforts involving net-shape processing, machining as a forming method, and the analysis of clinical failure. A rationale is presented for the further development of all-ceramic restorative systems. Current research topics receiving attention include microstructure/processing/property relationships, clinical failure mechanisms and in vitro testing, wear damage and wear testing, surface treatments, and microstructural modifications. The status of the field is critically reviewed with an eye toward future work. Significant improvements seem possible in the clinical use of ceramics based on engineering solutions derived from the study of clinically failed restorations, on the incorporation of higher levels of "biomimicry" in new systems, and on the synergistic developments in dental cements and adhesive dentin bonding.

[Evaluation of surface disinfectants utilized in dentistry].  

PubMed

Surface disinfection is a procedure carried out on the external parts of the dental equipment as well as on other items of the dental office. The aim of this study was to analyze the efficacy of 4 surface disinfectants utilized in dentistry: 77 degrees GL alcohol, phenolic compound (Duplofen), iodophor (PVP-I) and 77 degrees GL alcohol with 5% of chlorhexidine. Four surfaces of the equipment were analyzed in the study (the carter, the washbasin for hand-washing, the headrest of the chair and the external surface of the reflector), and the spray-wipe-spray procedure was carried out. From each surface, samples were collected by means of surface plates containing Mitis Salivarius bacitracin sucrose agar, Sabouraud Dextrose agar with chloramphenicol, MacConkey agar and blood agar, for counting mutans streptococci, Candida yeasts, gram-negative bacteria and total microorganisms, respectively (ufc/plate). The results were statistically analyzed by means of the Student's t test in order to compare the mean ufc/plate values. The most effective disinfectant was 77 degrees GL alcohol with 5% of chlorhexidine, mainly against gram-positive bacteria. Iodophor and phenolic compound were also effective in microbial reduction. 77 degrees GL alcohol was the least effective product - however, although it is not considered as a surface disinfectant, it produced, in this study, statistically significant microbial reduction after the disinfecting procedure.

Patient stratification for preventive care in dentistry.  

PubMed

Prevention reduces tooth loss, but little evidence supports biannual preventive care for all adults. We used risk-based approaches to test tooth loss association with 1 vs. 2 annual preventive visits in high-risk (HiR) and low-risk (LoR) patients. Insurance claims for 16 years for 5,117 adults were evaluated retrospectively for tooth extraction events. Patients were classified as HiR for progressive periodontitis if they had ? 1 of the risk factors (RFs) smoking, diabetes, interleukin-1 genotype; or as LoR if no RFs. LoR event rates were 13.8% and 16.4% for 2 or 1 annual preventive visits (absolute risk reduction, 2.6%; 95%CI, 0.5% to 5.8%; p = .092). HiR event rates were 16.9% and 22.1% for 2 and 1 preventive visits (absolute risk reduction, 5.2%; 95%CI, 1.8% to 8.4%; p = .002). Increasing RFs increased events (p < .001). Oral health care costs were not increased by any single RF, regardless of prevention frequency (p > .41), but multiple RFs increased costs vs. no (p < .001) or 1 RF (p = .001). For LoR individuals, the association between preventive dental visits and tooth loss was not significantly different whether the frequency was once or twice annually. A personalized medicine approach combining gene biomarkers with conventional risk factors to stratify populations may be useful in resource allocation for preventive dentistry (ClinicalTrials.gov, NCT01584479).

High-frequency noise in dentistry.  

PubMed

Earlier studies have revealed that dentists have higher hearing thresholds than expected. The aim of this study was to evaluate the noise levels of current dentistry equipment under very controlled conditions. This noise study was carried out in the Acoustics Laboratory of Kuopio Regional Institute of Occupational Health, the background noise of which is about 0 dB(A). Working noise was simulated by drilling a polyacetal plate. During drilling and idling, the noise of the hand pieces was measured over a reflecting plane on the hemisphere surface, the radius of which was 0.3 m, and 10 noise samples were picked for each hand piece. The average sound pressure level and the sound power level of the devices were calculated applying the standard ISO 3744. The measurement and analysis were done in the one-third octave bands of 25-80,000 Hz. The measuring instruments used were the B&K 4135 microphones, the B&K 2633 preamplifiers, the B&K 2811 multiplexer, and the B&K 2133 real-time analyzer with the ZT 0318 high-frequency expansion unit. During the simulated work, the average A-weighted sound pressure level of the new and old hand pieces was 76-82 dB(A), that of the power suction tube 77 dB(A), the saliva suction tube 75 dB(A), and the ultrasonic scaler 83 dB(A). The average ultrasound level of the ultrasonic scaler was 107 dB at the one-third octave band of 25,000 Hz. PMID:11975661

A new paradigm for operative dentistry  

PubMed Central

It is over 100 years since G V black gathered together most of the knowledge then current on the caries process and set clear parameters for the discipline of operative dentistry. His four-volume treatise set standards that were relevant for the times and, in fact, were so well described that they remained dominant in this discipline until quite recently. However, over the last 50 years there has been great progress in scientific method and in knowledge of the common diseases of the oral environment, including the caries process, so maybe it is time for change. The term “paradigm” describes a philosophy of science, a generally accepted model of how ideas relate to one another, forming a conceptual framework within which scientific research is carried out. Black defined the paradigm within which further research was to be conducted during the following years and the profession accepted his lead. However, it is not expected that the parameters of a profession should remain unchanged over a substantial period so it is suggested that the dental profession should, at this time, recognize a new paradigm. Improvements in scientific method have led to a better understanding of the oral environment, resulting in extensive changes for this profession. It is suggested that the standards set by Black should be now consigned to history and an entirely new paradigm adopted. First, the profession must recognize that dental caries is a bacterial disease and its primary efforts should be directed towards identification and elimination of the disease prior to initiating repair of the damage that it has caused. Preservation of natural tooth structure is then the next responsibility. There should be maximum use made of preventive strategies, including remineralization, followed by minimal intervention cavity designs and the use of bioactive restorative materials to restore the lesions. The profession should be prepared to move on.

The current status of dentistry, particularly pediatric dentistry, among the countries and territories of Asia.  

PubMed

The number of dentists in Japan may be too high. The ratio of dentists/population, in China, Indonesia, Thailand, and Malaysia, is less than 1 dentist for every 10,000 people. From this data, it can be seen that there is a shortage of dentists in China, Indonesia, Thailand, and Malaysia. The shortage of pediatric dentists in these Asian countries is serious, particularly in the Philippines where the number of children with dental caries is increasing. There is an urgent need to increase the number of pediatric dentists in these countries. However, one problem is that dental schools in the Philippines and Singapore, do not have a department of pediatric dentistry. PMID:10204450

The use of information and communication technology (ICT) in dentistry.  

PubMed

As the use of information and communication technology (ICT) becomes more widespread in dentistry the risk of breaching electronic commerce laws and patient confidentiality increases. It is necessary to be aware of the responsibilities internet usage entails, especially within a dental practice where the protection of patient information is of the utmost importance. More should be done to outline the various precautions that should be taken to ensure ICT security within the professional domain, as it would appear dentistry has been neglected with regard to receiving the proper ICT education, training and support systems.

Esthetic dentistry in the twenty-first century. Healthy beauty.  

PubMed

The goal of esthetic dentistry in the twenty-first century is to attain healthy beauty by harmonizing morphology and function. Morphologic beauty is achieved by using restorative techniques such as ceramo-metal restoration, all-ceramic restoration, laminate veneer, bleaching, and the treatment of malocclusion. Functional beauty is obtained by facilitating the primary functions of the stomatognathic organ, namely, mastication, speech, and craniomandibular stability. In the next century, esthetic dentistry must combine the present focus of morphologic beauty with the goals of functional beauty to attain true, healthy beauty. PMID:9891651

Modeling distributed feedback GaAs-based lasers in dentistry  

NASA Astrophysics Data System (ADS)

Distributed-feedback gallium-arsenide-based lasers with metal-gratings can generate stable wavelength at 980nm for applications in dentistry. This model uses the periodic optical waveguide method to calculate the coupling coefficient, which is a key parameter of laser performance. This model shows how the optical, geometrical, and material parameters depending on each other and how they affect the coupling coefficients in the laser waveguides. Numerical results compare the coupling coefficients of 980 nm lasers with those of 810 nm lasers. The modeling processes, including results, discussions, and physical interpretations, help to design and analyze lasers for more clinical and research applications in dentistry.

The galaxy cluster X-ray luminosity-gravitational mass relation in the light of the WMAP 3rd year data  

NASA Astrophysics Data System (ADS)

Context: .The 3rd year WMAP results mark a shift in best fit values of cosmological parameters compared to the 1st year data and the concordance cosmological model. Aims: .We test the consistency of the new results with previous constraints on cosmological parameters from the HIFLUGCS galaxy cluster sample and the impact of this shift on the X-ray luminosity-gravitational mass relation. Methods: .The measured X-ray luminosity function combined with the observed luminosity-mass relation are compared to mass functions predicted for given cosmological parameter values. Results: .The luminosity function and luminosity-mass relation derived previously from HIFLUGCS are in perfect agreement with mass functions predicted using the best fit parameter values from the 3rd year WMAP data (?_m=0.238, ?_8=0.74) and inconsistent with the concordance cosmological model (?_m=0.3, ?_8=0.9), assuming a flat Universe. Trying to force consistency with the concordance model requires artificially decreasing the normalization of the luminosity-mass relation by a factor of 2. Conclusions: .The shift in best fit values for ?m and ?8 has a significant impact on predictions of cluster abundances. The new WMAP results are now in perfect agreement with previous results on the ?_m-?8 relation determined from the mass function of HIFLUGCS clusters and other X-ray cluster samples (the "low cluster normalization"). We conclude that - unless the true values of ?m and ?8 differ significantly from the 3rd year WMAP results - the luminosity-mass relation is well described by their previous determination from X-ray observations of clusters, with a conservative upper limit on the bias factor of 1.5. These conclusions are currently being tested directly in a complete follow-up program of all HIFLUGCS clusters with Chandra and XMM-Newton.

The comparison of salivary level of estrogen and progesterone in 1st , 2nd and 3rd trimester in pregnant women with and without geographic tongue  

PubMed Central

Background: Geographic tongue (GT) was first reported as a wandering rash of the tongue in 1831; however, its etiopathogenesis remains unclear. Increased prevalence of GT has been documented in the pregnancy. The aim of this study was to compare the level of salivary estrogen and progesterone in pregnant women with and without GT. Materials and Methods: This analytical-descriptive study consisted of 26 pregnant women (13 with GT, 13 without GT) with an age range between 18 years and 45 years. The estrogen and progesterone level was measured during 1st , 2nd and 3rd trimester of pregnancy. Saliva sampling was performed to determine the level of sex hormones. The samples were stored at -80°C and determined by Eliza method. The results were analyzed by t-test and repeated measure ANOVA (? = 0.05). Results: The mean level of estrogen for control and case group was 49.4and 52.33 in the 1st , 71.05 and 74.12 in the 2nd and 109.1 and 112.16 in the 3rd trimester respectively. The mean level of progesterone was 0.72 and 0.72 in the 1st , 1.14 and 1.21 in the 2nd and 1.3 and 1.28 in the 3rd trimester of pregnancy for the control and case groups respectively. Even though, there was no significant difference regarding the level of sex hormones between case and control groups (P < 0.05), but the difference between the level of these hormones during 3 trimesters of pregnancy was significant in each group (P = 0.001). Conclusion: The level of sex hormones is not the only etiologic factor of GT in pregnant women, but other factors such as genetic potential, human leukocyte antigen marker and stress may aggravate the incidence of this lesion.

Modification of elastic stable intramedullary nailing with a 3rd nail in a femoral spiral fracture model - results of biomechanical testing and a prospective clinical study  

PubMed Central

Background Elastic stable intramedullary nailing (ESIN) is the standard treatment for displaced diaphyseal femoral fractures in children. However, high complication rates (10-50%) are reported in complex fractures. This biomechanical study compares the stiffness with a 3rd nail implanted to that in the classical 2C-shaped configuration and presents the application into clinical practice. Methods For each of the 3 configurations of ESIN-osteosynthesis with titanium nails eight composite femoral grafts (Sawbones®) with an identical spiral fracture were used: 2C configuration (2C-shaped nails, 2 × 3.5 mm), 3CM configuration (3rd nail from medial) and 3CL configuration (3rd nail from lateral). Each group underwent biomechanical testing in 4-point bending, internal/external rotation and axial compression. Results 2C and 3CM configurations showed no significant differences in this spiroid type fracture model. 3CL had a significantly higher stiffness during anterior-posterior bending, internal rotation and 9° compression than 2C, and was stiffer in the lateral-medial direction than 3CM. The 3CL was less stable during p-a bending and external rotation than both the others. As biomechanical testing showed a higher stability for the 3CL configuration in two (a-p corresponding to recurvation and 9° compression to shortening) of three directions associated with the most important clinical problems, we added a 3rd nail in ESIN-osteosynthesis for femoral fractures. 11 boys and 6 girls (2.5-15 years) were treated with modified ESIN of whom 12 were ‘3CL’; due to the individual character of the fractures 4 patients were treated with ‘3CM’ (third nail from medial) and as an exception 1 adolescent with 4 nails and one boy with plate osteosynthesis. No additional stabilizations or re-operations were necessary. All patients achieved full points in the Harris-Score at follow-up; no limb length discrepancy occurred. Conclusion The 3CL configuration provided a significantly higher stiffness than 2C and 3CM configurations in this biomechanical model. These results were successfully transmitted into clinical practice. All children, treated by 3CL or 3CM according to the individual character of each fracture, needed no additional stabilization and had no Re-Do operations. As a consequence, at our hospital all children with femoral diaphyseal fractures with open physis are treated with this modified ESIN-technique.

PubMed Central

Statement of Problem: The modern dentistry approach is moving toward preventive dentistry, an approach that has decreased the prevalence of caries within the past decades. Since some reports imply that dentists are not knowledgeable enough in this issue. Purpose: This study aimed to evaluate the attitude and awareness of future dental graduates toward preventive dentistry regarding gender and educational characteristics. Materials and Method: This cross-sectional study was performed on one hundred and forty questionnaires which were distributed among dental students of Isfahan province, Azad university of Khorasgan, Iran. Data regarding the level of awareness of dental students about preventive dentistry were recorded and analyzed by using the mean and standard deviations on scores as appropriated. Results: Majority of dental students were aware about the role of sugar in caries process, while only a minority were aware about the role of fluoridated toothpaste and brushing method in caries prevention. Most of the students (82.1%) were among the group with medium level of awareness. Compared with their female counterparts, male students had more knowledge about fluoride efficacy and general hygiene role in caries process. Conclusion: Dental students of  the Isfahan State University and Azad University of Khorasgan had acceptable levels of awareness about the role of sugar and fluoridated water in caries process, but were not aware enough about the role of fluoridated toothpaste in preventing dental caries.

Healthcare-associated viral and bacterial infections in dentistry  

PubMed Central

Infection prevention in dentistry is an important topic that has gained more interest in recent years and guidelines for the prevention of cross-transmission are common practice in many countries. However, little is known about the real risks of cross-transmission, specifically in the dental healthcare setting. This paper evaluated the literature to determine the risk of cross-transmission and infection of viruses and bacteria that are of particular relevance in the dental practice environment. Facts from the literature on HSV, VZV, HIV, Hepatitis B, C and D viruses, Mycobacterium spp., Pseudomonas spp., Legionella spp. and multi-resistant bacteria are presented. There is evidence that Hepatitis B virus is a real threat for cross-infection in dentistry. Data for the transmission of, and infection with, other viruses or bacteria in dental practice are scarce. However, a number of cases are probably not acknowledged by patients, healthcare workers and authorities. Furthermore, cross-transmission in dentistry is under-reported in the literature. For the above reasons, the real risks of cross-transmission are likely to be higher. There is therefore a need for prospective longitudinal research in this area, to determine the real risks of cross-infection in dentistry. This will assist the adoption of effective hygiene procedures in dental practice.

Specialist paediatric dentistry in Sweden 2008 - a 25-year perspective.  

PubMed

International Journal of Paediatric Dentistry 2010; 20: 313-321 Background. Paediatric dentistry in Sweden has been surveyed four times over the past 25 years. During this period postgraduate training, dental health, and the organization of child dental care have changed considerably. Aim. To investigate services provided by specialists in paediatric dentistry in Sweden in 2008, and to compare with data from previous surveys. Design. The same questionnaire was sent to all 30 specialist paediatric dental clinics in Sweden that had been used in previous surveys. Comparisons were made with data from 1983, 1989, 1996 and 2003. Results. Despite an unchanged number of specialists (N = 81 in 2008), the number of referrals had increased by 16% since 2003 and by almost 50% since 1983. There was greater variation in reasons for referrals. The main reason was still dental anxiety/behaviour management problems in combination with dental treatment needs (27%), followed by medical conditions/disability (18%), and high caries activity (15%). The use of different techniques for conscious sedation as well as general anaesthesia had also increased. Conclusions. The referrals to paediatric dentistry continue to increase, leading to a heavy work load for the same number of specialists. Thus, the need for more paediatric dentists remains. PMID:20545788

Forensic dentistry in human identification: A review of the literature  

PubMed Central

An update is provided of the literature on the role of odontology in human identification, based on a PubMed-Medline search of the last 5 years and using the terms: “forensic dentistry” (n = 464 articles), “forensic odontology” (n = 141 articles) and “forensic dentistry identification” (n = 169 articles). Apart from these initial 774 articles, others considered to be important and which were generated by a manual search and cited as references in review articles were also included. Forensic dentistry requires interdisciplinary knowledge, since the data obtained from the oral cavity can contribute to identify an individual or provide information needed in a legal process. Furthermore, the data obtained from the oral cavity can narrow the search range of an individual and play a key role in the victim identification process following mass disasters or catastrophes. This literature search covering the last 5 years describes the novelties referred to buccodental studies in comparative identification, buccodental evaluation in reconstructive identification, human bites as a method for identifying the aggressor, and the role of DNA in dental identification. The oral cavity is a rich and noninvasive source of DNA, and can be used to solve problems of a social, economic or legal nature. Key words:Forensic identification, DNA, forensic dentistry, rugoscopy, cheiloscopy, saliva.

ED overcrowding: the Ontario approach.  

PubMed

Ontario is Canada's most populous province, with approximately 12 million people and 130 emergency departments (EDs). Canada has a national single-payer universal health care system, but provinces are responsible for administration. After years of problems and failed attempts to address chronic ED overcrowding, in April 2008 Ontario embarked on an ambitious program to improve system performance through targeted investments (initially CAN$500 million over 3 years) and realigned incentives. Supporting the program were requirements for hospitals to submit timely data and targets for length of stay (LOS) and annual improvements; results are publicly reported. The program has been continued this year. While not all our provincial level targets have been met as yet, major improvements have been made, especially in access to care and LOS in the ED for patients eventually discharged home. The greatest improvements were made among the cohort of mainly urban, high-volume EDs that had the worst performance at baseline. This presentation will highlight some of the controversies and challenges and key lessons learned. Overall, the Ontario experience suggests ED overcrowding is a soluble problem, but requires a system-level intervention. PMID:22168186

Pulsed lasers in dentistry: sense or nonsense?  

NASA Astrophysics Data System (ADS)

The great interest in the field of laser applications in dentistry provokes the question, if all these new techniques may really fulfill advantages, which are expected after initial in-vitro studies. Whereas laser surgery of soft oral tissues has been developed to a standard method, laser treatment of dental hard tissues and the bone are attended with many unsolved problems. Different laser types, especially pulsed lasers in a wide spectrum of wavelengths have been proofed for dental use. Today neither the excimer lasers, emitting in the far uv-range from 193 to 351 nm, nor the mid-infrared lasers like Nd:YAG (1,064 ?m), Ho:YAG (2,1 ?m) and Er:YAG (2,96 ?m) or the C02-laser (10,6 ?m) show mechanism of interaction more carefully and faster than a preparation of teeth with diamond drillers. The laser type with the most precise and considerate treatment effects in the moment is the short pulsed (15 ns) ArF-excimer laser with a wavelength of 193 nm. However this laser type has not yet the effectivity of mechanical instruments and it needs a mirror system to deliver the radiation. Histological results point out, that this laser shows no significant pathological alterations in the adjacent tissues. Another interesting excimer laser, filled with XeCI and emitting at a wavelength of 308 nm has the advantage to be good to deliver through quartz fibers. A little more thermal influence is to be seen according to the longer wavelength. Yet the energy density, necessary to cut dental hard tissues will not be reached with the laser systems available now. Both the pulsed Er:YAG- (2,94 ?m, pulse duration 250 s) and the Ho:YAG -laser (2,1 ?m, pulse duration 250 ?s) have an effective coupling of the laser energy to hydrogeneous tissues, but they do not work sufficient on healthy enamel and dentine. The influence to adjacent healthy tissue is not tolerable, especially in regard of the thermal damage dentine and pulp tissues. Moreover, like the 193 nm ArF-excimer laser radiation the Er:YAG-laser radiation could also only be delivered via mirror systems, while the radiation of the Ho:YAG-Laser can be well transmitted through quartz fibers. The energy of the well known and in other medical disciplines often used Nd:YAG - laser (1,064 ?m, pulse duration 150 us) laser can be transmitted through fiber systems without problems, but this laser has not the effectivity to work sufficient on healthy hard dental tissues due to the high transmission in mineralized dental tissues. The thermal injuries of this laser type are not tolerable. The short pulsed TEA-C02-laser (9,6 and 10,6 ?m, pulse duration 200-300 ns), which has an excellent coupling not only to the hydrogeneous tissues but also to the mineralized tissues could be an alternative system to prepare dental tissues. The greatest disadvantage of this system is the noneffective delivery of the light energy through flexible fiber systems, which are still in development. Another good chance perhaps will have the q-switched Neodym, Erbium and Holmium:- YAG lasers with pulse durations of about some hundred ns. Both, possible thermal influences and possible disruptive effects should be small enough to let the adjacent tissues undamaged.

Efficacy of a 3rd generation high-throughput sequencing platform for analyses of 16S rRNA genes from environmental samples.  

PubMed

Longer sequences of the bacterial 16S rRNA gene could provide greater phylogenetic and taxonomic resolutions and advance knowledge of population dynamics within complex natural communities. We assessed the accuracy of a Pacific Biosciences (PacBio) single molecule, real time (SMRT) sequencing based on DNA polymerization, a promising 3rd generation high-throughput technique, and compared this to the 2nd generation Roche 454 pyrosequencing platform. Amplicons of the 16S rRNA gene from a known isolate, Shewanella oneidensis MR1, and environmental samples from two streambed habitats, rocks and sediments, and a riparian zone soil, were analyzed. On the PacBio we analyzed ~500 bp amplicons that covered the V1-V3 regions and the full 1500 bp amplicons of the V1-V9 regions. On the Roche 454 we analyzed the ~500 bp amplicons. Error rates associated with the isolate were lowest with the Roche 454 method (2%), increased by more than 2-fold for the 500 bp amplicons with the PacBio SMRT chip (4-5%), and by more than 8-fold for the full gene with the PacBio SMRT chip (17-18%). Higher error rates with the PacBio SMRT chip artificially inflated estimates of richness and lowered estimates of coverage for environmental samples. The 3rd generation sequencing technology we evaluated does not provide greater phylogenetic and taxonomic resolutions for studies of microbial ecology. PMID:23999276

Hepatitis B: Knowledge, Vaccine Situation and Seroconversion of Dentistry Students of a Public University  

PubMed Central

Background Viral hepatitis B (VHB) is an occupational risk for dentists. It is necessary that dental students start clinical practice immunized with the vaccine, response monitored and informed about the means of transmission of the disease. Rarely, there are studies, which evaluate concomitantly knowledge of these academics and their vaccine situation. Objectives To evaluate the knowledge about Hepatitis B, the vaccine situation and the immunization status of dental students and to investigate the probable correlation between the status of immunization, vaccination membership and adherence to the test of seroconversion and associated factors. Patients and Methods 189 students from the dentistry course at the Federal University of Piaui (UFPI) who attended from the 3rd to 9th period were invited to participate in the research. Their knowledge about HBV, attitude regarding protection and their vaccine situation were assessed through a self-administered form. Antibodies against surface antigens of Hepatitis B virus (Anti-HBs) and against the antigens of the virus nucleous of Hepatitis B (Anti-HBc total) were measured qualitatively using the enzyme-linked immunosorbent assay (ELISA). Results Of the 179 students surveyed, 58.1% knew about the degree of virulence of the Hepatitis B virus (HBV). As to the means of transmission, 98.3% considered blood transmission, 82.6% plates and cutlery, 15.6% cough and 12.3% vertical transmission. Most students (87.4%) knew that they should take 3 doses of the vaccine and 62.2% completed the immunization schedule. A minority of students (48.6%) knew the about the Anti-HBs test and 5.6% took the test. Among the students who reported having taken three doses of the vaccine, 12.5% were not seroconverted. There was no significant correlation between the variables. Conclusions Dental academics were unsure about the means of infection and prevention against HBV. Many of them had not completed the immunization scheme and did not have the test of seroconversion. The serological analysis revealed unprotection, even after students completed the vaccination schedule.

EDS: The Experimental Design Simulator  

NASA Astrophysics Data System (ADS)

A computer program was developed to realistically simulate a broad variety of experiments with established factors and response models. The program, entitled the 'Experimental Design Simulator' (EDS) is a 32-bit Microsoft WindowsTM application that simulates experiments for the purpose of evaluating experimental parameters and experimental designs. EDS is applied to teaching experimental statistics and experimental design, while improving cost effectiveness. The program was developed to demonstrate the application of stochastic simulation methods to experimental design evaluation. EDS simulates ten different data distributions so that complex multi-factor, multi-distribution systems can be evaluated where propagation of error methods can not be applied. Multiple responses can be simulated for dependent and independent functions, and response values can be used as factors in subsequent response models. Covariant and interacting factors may be incorporated as multiple factor based responses and applied in secondary responses. Complex experimental systems can be simulated, and data can be processed and evaluated realistically. Complex experiments can be examined and evaluated with minimal cost. Results from actual experiments can be compared to simulated experimental results. The stochastic approach to experimental system and design evaluation as demonstrated by EDS is a powerful tool in improving the utilization, effectiveness and efficiency of experimental design in research and has an application in improving teaching methods.

A Kinesthetic Learning Approach to Earth Science for 3rd and 4th Grade Students on the Pajarito Plateau, Los Alamos, NM  

NASA Astrophysics Data System (ADS)

Current efforts towards Earth Science literacy in New Mexico are guided by the New Mexico Science Benchmarks [1]. We are geoscience professionals in Los Alamos, NM who believe there is an important role for non-traditional educators utilizing innovative teaching methods. We propose to further Earth Science literacy for local 3rd and 4th grade students using a kinesthetic learning approach, with the goal of fostering an interactive relationship between the students and their geologic environment. We will be working in partnership with the Pajarito Environmental Education Center (PEEC), which teaches the natural heritage of the Pajarito Plateau to 3rd and 4th grade students from the surrounding area, as well as the Family YMCA’s Adventure Programs Director. The Pajarito Plateau provides a remarkable geologic classroom because minimal structural features complicate the stratigraphy and dramatic volcanic and erosional processes are plainly on display and easily accessible. Our methodology consists of two approaches. First, we will build an interpretive display of the local geology at PEEC that will highlight prominent rock formations and geologic processes seen on a daily basis. It will include a simplified stratigraphic section with field specimens and a map linked to each specimen’s location to encourage further exploration. Second, we will develop and implement a kinesthetic curriculum for an exploratory field class. Active engagement with geologic phenomena will take place in many forms, such as a scavenger hunt for precipitated crystals in the vesicles of basalt flows and a search for progressively smaller rhyodacite clasts scattered along an actively eroding canyon. We believe students will be more receptive to origin explanations when they possess a piece of the story. Students will be provided with field books to make drawings of geologic features. This will encourage independent assessment of phenomena and introduce the skill of scientific observation. We expect students to develop comprehension of basic geologic concepts and processes such as erosion and sediment transport, caldera formation, ash flows, crystallization and volcanic cooling features. More importantly, we hope students will become excited about their geologic environment and pursue further engagement. We will attempt to quantify student comprehension and engagement by administering simple questionnaires before and after exposure to both the PEEC display and the field class. ____________________________________________________________ [1] New Mexico Science Content Standards, Benchmarks, and Performance Standards.

Er:YAG and adhesion in conservative dentistry : clinical overview  

PubMed Central

The notion of utilizing laser technology in conservative dentistry was proposed in 1990 by Hibst and Keller, who introduced the possibility of using an Er:YAG laser as alternative to conventional instruments such as the turbine and micro-motor. In subsequent years a continuing effort has been made by clinicians, researchers and commercial companies to improve the technology. The aim of this clinical study is to demonstrate, by the description of different clinical cases, the possibilities and the advantages of using Er:YAG lasers in conservative dentistry and to show that better results may be achieved in terms of stronger adhesion, less invasiveness, reduced pain as well as greater comfort and satisfaction of patients.

Can we learn, teach and practise dentistry anywhere, anytime?  

PubMed

Dentistry-related applications for mobile phones are becoming a popular way of accessing information for students, practitioners and patients. The aim of this article is to review the use of mobile technology, such as 'apps', within dentistry. Over time, there has been a change from desktop learning (D-learning) to mobile learning (M-learning) and this has only been possible with the aid of electronic media and the growth of the Internet. In spite of the increase in mobile applications, there is a need for any information to have a strong underlying evidence base. Several good examples of dental applications which take full advantage of this electronic medium are available. However, developers of mobile applications should provide good quality, peer-reviewed evidence to validate their material. PMID:24113956

Demonstration of inscription and ablation of phase masks for the production of 1st, 2nd, and 3rd order FBG gratings using a femtosecond laser  

NASA Astrophysics Data System (ADS)

We present to the best of our knowledge the first example of femtosecond laser inscription/ablation of phase/amplitude masks for the demonstrated purpose of inscribing Bragg gratings in optical fibers. We show that the utilization of a femtosecond laser for the mask production allows for great flexibility in controlling the mask period. The masks are used to produce 1st, 2nd and 3rd order fiber Bragg gratings (FBGs) in SMF-28. The work demonstrates the proof of concept and flexibility for the use of femtosecond lasers for the rapid prototyping of complex and reproducible mask structures. Our inscription studies are augmented by considerations of three-beam interference effects that occur as a result of the strong zeroth-order component that is present in addition to higher-order diffraction components.

Tailoring the GVHD prophylaxis regimen according to transplantation associated toxicities-Substituting the 3rd dose of methotrexate to mycophenolate mofetil.  

PubMed

We hypothesized that in patients with early post allogeneic transplantation toxicities, the omission of the 3rd dose of methotrexate with concomitant starting of MMF would favorably affect complications. We found a higher incidence of grade 2-4 acute GVHD in patients given two doses methotrexate and MMF (n=31) compared to those given three courses of methotrexate (n=70) (p=.004), while grade 3-4 was similar. Other transplantation outcomes, including overall regimen-related-toxicity, were comparable. We conclude that tailoring the GVHD prophylaxis regimen may decrease the early post transplantation complications, however this come at the extent of a higher incidence of non-severe acute GVHD.

Overview of Deployed EDS Technologies  

SciTech Connect

The term explosive detection system (EDS) is used by the TSA to describe equipment that is certified to detect explosives in checked bags. The EDS, as certified, by the TSL must consist of device for interrogating a bag and an automated detection algorithm (ATD) for evaluating the results of the interrogation. We only consider CT as the interrogation device in this report. A schematic drawing of a CT-based EDS is shown in Figure 2. The output of the ATD is the binary decision of alarm or non-alarm. Alarms may true- or false-positives. Non-alarms may be true- or false-negatives. False positives are also denoted false alarms. The true detection means that the ATD reports an alarm when a threat is present in the scanned bag. The probability of detecting a threat given that a threat is present is denoted the probability of detection (PD). The probability of false alarm (PFA) is the case when an alarm is reported when a threat is not present in a bag. Certification in this context means passing tests for PD and PFA at the TSL. The results of the EDS include CT cross-sectional images of the bag and specifics about the alarmed objects generated by ATD. These results are presented on a display so that a person may override the decision of ATD and declare the alarm to be a non-alarm. This process is denoted clearing. Bags that are not cleared by the person are sent to a secondary inspection process. Here the bags may be opened or assessed with explosive trace detection (ETD) in order to clear the bags. Bags that are not cleared at this point are evaluated by an ordinance disposal team. The CT scanner along with ATD is denoted Level 1 screening. The process of clearing on a display is denoted Level 2 screening. Secondary inspection is denoted Level 3 screening. Vendors of the deployed EDSs supply the TSA with equipment for all three levels. Therefore, the term EDS may include the equipment provided for Levels 1, 2 and 3. A schematic diagram of an EDS and the levels of screening are shown in Figure 7. The decision processes used as a bag is scanned and cleared is shown in Figure 8. Shield alarms and exceptions are discussed below. Since most alarms are false alarms, the probability of alarm is often times denoted the probability of a false alarm. The expenses associated with clearing false alarms occur in Levels 2 and 3.

Stem cells in dentistry--Part II: Clinical applications.  

PubMed

New technologies that facilitate solid alveolar ridge augmentation are receiving considerable attention in the field of prosthodontics because of the growing requirement for esthetic and functional reconstruction by dental implant treatments. Recently, several studies have demonstrated potential advantages for stem-cell-based therapies in regenerative treatments. Mesenchymal stem/stromal cells (MSCs) are now an excellent candidate for tissue replacement therapies, and tissue engineering approaches and chair-side cellular grafting approaches using autologous MSCs represent the clinical state of the art for stem-cell-based alveolar bone regeneration. Basic studies have revealed that crosstalk between implanted donor cells and recipient immune cells plays a key role in determining clinical success that may involve the recently observed immunomodulatory properties of MSCs. Part II of this review first overviews progress in regenerative dentistry to consider the implications of the stem cell technology in dentistry and then highlights cutting-edge stem-cell-based alveolar bone regenerative therapies. Factors that affect stem-cell-based bone regeneration as related to the local immune response are then discussed. Additionally, pre-clinical stem cell studies for the regeneration of teeth and other oral organs as well as possible applications of MSC-based immunotherapy in dentistry are outlined. Finally, the marketing of stem cell technology in dental stem cell banks with a view toward future regenerative therapies is introduced. PMID:23137671

Use of Artelon® Cosmetic in soft tissue augmentation in dentistry  

PubMed Central

Background Soft tissue augmentation is a widely used procedure in partially and fully edentulous patients to increase soft tissue volume. Polyurethanes have been used for scaffolds in a variety of implantable devices. Artelon® is a degradable polyurethane that has been manufactured as fibers, films, and porous scaffolds to be used for various purposes. In this review, the characteristics of Artelon are described, and its clinical applications in orthopedics, dermatology, cardiovascular medicine, and dentistry are also discussed. Methods A Medline (PubMed) search was conducted, and articles published in English were included. Keywords, including “Artelon”, “polyurethanes”, “soft tissue augmentation”, “biocompatibility”, “resorption”, “mechanical stability”, and “complications” were used in different combinations. Titles and abstracts were screened, and full text article analyses were performed. Results Most of the studies reported orthopedic, dermal, and myocardial applications. There were only a few reports related to dental and implant applications. Artelon has been successfully used for reinforcement of soft tissues, including the rotator cuff, Achilles, patellar, biceps, and quadriceps tendons in orthopedic surgery, and is used clinically for the treatment of osteoarthritis in the hand, wrist, and foot. One type of Artelon material, Artelon Cosmetic, has been used in the dental field to increase soft tissue volume, and stable results are achieved for up to 6 months. This material is reported to be easily handled when cut to the desired shape, with little additional time needed for manipulation during surgery, eliminates the need for connective tissue autografts, and thereby decreases patient morbidity and postoperative discomfort, with increased likelihood of a positive subjective outcome. Conclusion Artelon may be applied in the dental field to increase soft tissue volume. Further studies of various applications in dentistry with long-term results are needed to confirm the safety and efficacy of this material before it can be used on a routine basis in dentistry.

We conducted ground-based measurements with the Ames Airborne Tracking 6-channel Sunphotometer (AATS-6) during the 3rd Water Vapor IOP (WVIOP3), September 18 - October 8, 2000 at the SGP ARM site. For this deployment our primary result was columnar water vapor (CWV) obtained from continuous solar transmittance measurements in the 0.94-micron band. In addition, we simultaneously measured aerosol optical depth (AOD) at 380, 450, 525, 864 and 1020 nm. During the IOP, preliminary results of CWV and AOD were displayed in real-time. The result files were made available to other investigators by noon of the next day. During WVIOP3 those data were shown on the daily intercomparison plots on the IOP web-site. Our preliminary results for CWV fell within the spread of values obtained from other techniques. After conclusion of WVIOP3, AATS-6 was shipped directly to Mauna Loa, Hawaii for post-mission calibration. The updated calibration, a cloud screening technique for AOD, along with other mostly cosmetic changes were applied to the WVIOP3 data set and released as version 0.1. The resulting changes in CWV are small, the changes in AOD and Angstrom parameter are more noticeable. Data version 0.1 was successfully submitted to the ARM External Data Center. In the poster we will show data examples for both CWV and AOD. We will also compare our CWV results with those obtained from a GPS (Global Positioning System) slant path method.

The freeze-fractured median eminence. I. Development of intercellular junctions in the ependyma of the 3rd ventricle of the rat.  

PubMed

Ependymal junctions in both the ventro-lateral wall and infundibular floor of the 3rd ventricle were examined in adult, young, neonatal, and fetal rats in freeze-fracture preparations. During late fetal and early postnatal life, tight junctions developed in both ventro-lateral and floor ependyma with, first, the appearance of an area of waffle-like or honeycomb texture in the membrane where tight junctions will appear; second, the decoration of P-face crests of this honeycomb with individual particles; and lastly, fusion of these particles into smooth strands. In adults, tight junctions were rare in the lateral ependyma, but persisted on the floor as a loose network. Many small ependymal gap junctions were already present at the earliest fetal stage (17 days) examined. They occupied significantly larger proportions of the membranes on the ventro-lateral wall than on the floor throughout the time course due to an increase in their size but not in their numbers. The smallest gap junctions were regarded as the newest in a process of renewal throughout life. The development of both junctional types parallels what is known on the onset of neuroendocrine functions in the median eminence. In the rat, this is apparently just before, at, or just after birth.

The perceptions of professional soccer players on the risk of injury from competition and training on natural grass and 3rd generation artificial turf  

PubMed Central

Background The purpose of this study was to describe professional soccer players’ perceptions towards injuries, physical recovery and the effect of surface related factors on injury resulting from soccer participation on 3rd generation artificial turf (FT) compared to natural grass (NG). Methods Information was collected through a questionnaire that was completed by 99 professional soccer players from 6 teams competing in Major League Soccer (MLS) during the 2011 season. Results The majority (93% and 95%) of the players reported that playing surface type and quality influenced the risk of sustaining an injury. Players believed that playing and training on FT increased the risk of sustaining a non-contact injury as opposed to a contact injury. The players identified three surface related risk factors on FT, which they related to injuries and greater recovery times: 1) Greater surface stiffness 2) Greater surface friction 3) Larger metabolic cost to playing on artificial grounds. Overall, 94% of the players chose FT as the surface most likely to increase the risk of sustaining an injury. Conclusions Players believe that the risk of injury differs according to surface type, and that FT is associated with an increased risk of non-contact injury. Future studies should be designed prospectively to systematically track the perceptions of groups of professional players training and competing on FT and NG.

Study motives, career choices and interest in paediatric dentistry among final year dental students in Nigeria  

PubMed Central

Background Students’ motives for studying Dentistry have been a subject of interest for years because of the potential for understanding the psychological makeup and subsequent job satisfaction for the dentist. It is also useful in identifying expectations of the profession. This study therefore tried to identify study motives and career preferences of dental students especially with respect to the practice of paediatric dentistry. Methods This was a cross-sectional study using a self-administered questionnaire. The final year students in six dental schools in Nigeria were required to fill the questionnaire. Students were asked to rank their motives and career preferences on a Likert like scale with points ranging from 0–5 where 0 represented a factor that had no influence on their decision and 5 represented a very influential factor. The underlying dimensions for study motives, career preference, impression about and motive for interest in the practice of paediatric dentistry were identified using factor analysis. Results One hundred and seventy nine of 223 students (80.3%) participated in this study. Motives for the practice of dentistry included characteristics of the profession, altruism and intellectual challenges, existence of artistic theme in dentistry and parent’s recommendation. Overall, 67.1% of respondents indicated interest in postgraduate studies and 50.8% were interested in paediatric dentistry practice. The main motives for showing interest in the practice of paediatric dentistry were ‘personal interest, professional interest and interest of significant others in children’, and ‘family influence’. Significantly more males than females were interested in the practice of paediatric dentistry though the motives for interest in the practice of paediatric dentistry did not differ significantly by sex or age. Conclusion The non-significant sex difference in the motives for interest in the practice of paediatric dentistry is a possible reflection of changes in strong cultural themes in the motives for career choices in Nigeria.

Current perspectives: calcium phosphate nanocoatings and nanocomposite coatings in dentistry.  

PubMed

The purpose of coatings on implants is to achieve some or all of the improvements in biocompatibility, bioactivity, and increased protection from the release of harmful or unnecessary metal ions. During the last decade, there has been substantially increased interest in nanomaterials in biomedical science and dentistry. Nanocomposites can be described as a combination of two or more nanomaterials. By this approach, it is possible to manipulate mechanical properties, such as strength and modulus of the composites, to become closer to those of natural bone. This is feasible with the help of secondary substitution phases. Currently, the most common composite materials used for clinical applications are those selected from a handful of available and well-characterized biocompatible ceramics and natural and synthetic polymers. This approach is currently being explored in the development of a new generation of nanocomposite coatings with a wider range of oral and dental applications to promote osseointegration. The aim of this review is to give a brief introduction into the new advances in calcium phosphate nanocoatings and their composites, with a range of materials such as bioglass, carbon nanotubes, silica, ceramic oxide, and other nanoparticles being investigated or used in dentistry.

Laser sources in dentistry and radiation safety regulations  

NASA Astrophysics Data System (ADS)

Nowadays laser sources are largely adopted in dentistry due to their unique properties making them good candidates to substitute traditional scalpel and conventional diamond bur in the surgery of the soft and hard oral tissue, respectively. The large use of laser sources outside the research laboratories without the need of highly specialized personnel can ask for a widespread knowledge of safety issues related to this kind of equipment. The main hazard of accidental exposures regards eyes injury but increasing the power of the laser beam also skin can be involved. Safety legislations in Europe and U.S.A. take into account non ionizing radiations and laser radiation for the hazards for the health deriving from physical agents. Laser safety standards introduce 3 useful parameters for hazard characterization: "Accessible Emission Limit" (AEL), "Maximum Permissible Exposure" (MPE) and "Nominal Ocular Hazard Distance" (NOHD). We measured the MPE and NOHD for Er:YAG and other laser sources currently adopted in dentistry and we compared our results with data elaborated from standards in order to single out safe and comfortable working conditions. In fact an experimental assessment of the hazard parameters and the comparison with those of reference from safety standards turns out to be useful in order to estimate the residual hazard that can be still present after applying all the engineering protection and administrative rules.

Does 3rd age plus 3rd world equal 3rd class?  

PubMed

The patterns of care of the aged population are being influenced by demographic changes, migration, and industrialization in developing countries. There is no longer a secure place for the elders in the community as chiefs, sages, or useful members of the household. In very large mega-cities the aged living in an extended family are more prone to psychological problems than in a lone living situation. There are many variations in the degree of abandonment or loss of dignity, which are described in examples from Vilcabamba, Potosi, Lima, and Belize. For example in Belize, there are no cities to migrate to so people leave to seek their fortunes in the US or the UK. Solutions are possible within the community. The experiences of HelpAge International are reported for Pro Vida, Colombia; India; and Sri Lanka. In Colombia efforts were made to acquire a bakery so that the elderly could be employed in bread baking, donating loaves to institutions, and selling half the loaves on the street. Other projects involved improving living conditions for lone old people in shanty towns and training social workers. The institutional aim was to concentrate on a locale. Attention was given to providing instruction in classrooms to enlighten youth about the needs of the elderly. HelpAge in India concentrated on eye problems of the elderly in remote areas through awareness and fundraising campaigns. HelpAge Sri Lanka has set up seminars and training programs which have been models for similar programs in Thailand. Shared experience with the problems of aged beggars suggests that funding must come from nongovernmental agencies. The cultivation and sale of herbs by the elderly was promoted in Vilcabamba; in Jamaica a memory bank was established for preserving cultural traditions. Abandoned industries have been revived. The needs of the organizers, who are primarily volunteers, are organization skills. Governments can supplement meager funds by enhancing traditional life, by removing obstacles to foreign aid, and by avoiding spending on prestige projects and questionable projects imported from Western countries. Reinforcement of families and of local community groups is needed. PMID:12286290

Instability of EDS maglev systems  

SciTech Connect

Instabilities of an EDS maglev suspension system with 3 D.O.F. and 5 D.O.F. vehicles traveling on a double L-shaped set of guideway conductors have been investigated with various experimentally measured magnetical force data incorporated into the theoretical models. Divergence and flutter are obtained from both analytical and numerical solutions for coupled vibration of the 3 D.O.F. maglev vehicle model. Instabilities of five direction motions (heave, slip, rill, pitch and yaw) are observed for the 4 D.O.F. vehicle model. It demonstrates that system parameters, such as, system damping, vehicle geometry and coupling effects among five different motions play very important roles in the occurrence of dynamic instabilities of maglev vehicles.

East Carolina University School of Dentistry: impact on access disparities.  

PubMed

Under the "Plan for Dentistry in North Carolina," the existing dental school will increase its class size and enhance its research efforts and a new dental school will be opened on the campus of East Carolina University. These initiatives are designed to address a growing gap between oral health needs and capacity to meet that need in the state, especially in rural areas. The new school will focus on educating well-qualified primary care dentists who desire to address the challenges of providing care in the rural and underserved areas of the state. This paper describes the objectives, quality, research, patient care model, economic model, recruitment and financial considerations for students, and community benefits of the program. A key feature of the ECU program will be the fourth-year experience in Service Learning Centers located in rural communities. PMID:19413047

[Woman and career: an unhappy marriage? A study model: dentistry].  

PubMed

Women's participation in the professions is steadily increasing. This study is a quantitative assessment of male and female career patterns in dentistry and of the role of marriage in any gender gap. A 1997 survey explored the professional activity of Flemish dentists. There is no educational disparity between dentists, female dentists enter the profession on an equal footing with their male colleagues. Therefore any other career influencing factors reveal themselves relatively clearly. Dependent variable was income; independent variables were gender and marriage. Female dentists scored lower than male dentists in each career phase; marriage made no significant difference. However, marriage turned out to be an important positive factor in the career of male dentists. Women dentists marry significantly later and less than their male colleagues. Further research, also of a qualitative nature, is necessary to evaluate the professional and social impact of this substantial gender difference. PMID:12649971

Laser in dentistry: An innovative tool in modern dental practice  

PubMed Central

The term LASER is an acronym for ‘Light Amplification by the Stimulated Emission of Radiation’. As its first application in dentistry by Miaman, in 1960, the laser has seen various hard and soft tissue applications. In the last two decades, there has been an explosion of research studies in laser application. In hard tissue application, the laser is used for caries prevention, bleaching, restorative removal and curing, cavity preparation, dentinal hypersensitivity, growth modulation and for diagnostic purposes, whereas soft tissue application includes wound healing, removal of hyperplastic tissue to uncovering of impacted or partially erupted tooth, photodynamic therapy for malignancies, photostimulation of herpetic lesion. Use of the laser proved to be an effective tool to increase efficiency, specificity, ease, and cost and comfort of the dental treatment.

Piezosurgery applied to implant dentistry: clinical and biological aspects.  

PubMed

Piezosurgery is a new and modern technique of bone surgery in implantology. Selective cutting is possible for different ultrasonic frequencies acting only in hard tissues (mineralized), saving vital anatomical structures. With the piezoelectric osteotomy technique, receptor site preparation for implants, autogenous bone graft acquistition (particles and blocks), osteotomy for alveolar bone crest expansion, maxillary sinus lifting, and dental implant removal can be performed accurately and safely, providing excellent clinical and biological results, especially for osteocyte viability. The aim of this review was, through literature review, to present clinical applications of piezosurgery in implant dentistry and outline their advantages and disadvantages over conventional surgical systems. Moreover, this study addressed the biological aspects related to piezosurgery that differentiate it from those of bone tissue approaches. Overall, piezosurgery enables critical operations in simple and fully executable procedures; and effectively, areas that are difficult to access have less risk of soft tissue and neurovascular tissue damage via piezosurgery.

Role of deoxyribonucleic acid technology in forensic dentistry  

PubMed Central

In the last few years, Deoxyribonucleic Acid (DNA) analysis methods have been applied to forensic cases. Forensic dental record comparison has been used for human identification in cases where destruction of bodily tissues or prolonged exposure to the environment has made other means of identification impractical, that is, after fire exposure or mass disaster. Teeth play an important role in identification and criminology, due to their unique characteristics and relatively high degree of physical and chemical resistance. The use of a DNA profile test in forensic dentistry offers a new perspective in human identification. The DNA is responsible for storing all the genetic material and is unique to each individual. The currently available DNA tests have high reliability and are accepted as legal proofs in courts. This article gives an overview of the evolution of DNA technology in the last few years, highlighting its importance in cases of forensic investigation.

Theoretical knowledge in implant dentistry for undergraduate students.  

PubMed

Implant therapy has evolved into an important part of daily dental practice. Appropriate knowledge of diagnostic and therapeutic options with dental implant therapy is, therefore, mandatory for dental students. The present consensus paper describes the theoretical knowledge as a foundation to the teaching of implant dentistry at the undergraduate level. Students need a solid basic knowledge about biological prerequisites and clinical procedures leading to successful implant treatment and, in particular, an understanding of the importance of embedding implants into the overall treatment concept. Among others this includes aspects of bone and soft tissue integration of dental implants, as well as aspects of materials that are used in implant dentistry. The students should also be able to differentiate between low, medium and high-risk situations, which assumes that they have knowledge about a proper clinical examination. Furthermore, the students need to be able to inform the patient about the different treatment options and their advantages and disadvantages. Frequently, a choice has to be made between an FDP anchored on teeth and an implant-borne reconstruction. This is highly influenced by the long-term prognosis of the different treatment options. In order to perform implant placement in uncomplicated cases and to give appropriate patient information, adequate knowledge of surgical procedure and surgical complications is mandatory. Furthermore, the dentist needs to be competent in evaluating clinical situations and in advising patients about the suitability of the different options, e.g. removable or fixed reconstructions. It is possible that peri-implant tissue destruction may be a more common finding during long-term service of implant-borne reconstructions than was previously believed. The dentist needs knowledge about etiology and pathogenesis of peri-implantitis and should know how to provide an effective maintenance care programme. In cases of peri-implantitis the student should be knowledgeable regarding suitable interventions. PMID:19281512

Stages of Geoinformation Evolution Related to the Territories Described in the Bible - from the 3Rd Millennium B.C. to Modern Times  

NASA Astrophysics Data System (ADS)

The paper presents consecutive stages of the evolution of geoinformation related to the territories of the events described in the Bible. Two geoinformation sources are presented: the Bible and non-Bible sources. In the Bible there is much, often some highly detailed information regarding terrain topography. The oldest non-Bible sources are incorporated in the ancient documents, which were discovered in Egypt and Mesopotamia. Some of them are related to the 3rd millen- nium B.C. The further stages are related to the onomasticons and itineraries written by travellers and pilgrims to the Holy Land. The most famous onomasticons include: onomasticons prepared by bishop Eusebius from Caesarea and those pre- pared by St. Jerome. One of the oldest maps of Palestine's territory is the so-called mosaic map of Madaba dated to 565. In the 15th century several Bible maps were edited. The most rapid evolution occurred in the 16th and 17* centuries, when the world famous cartographers such as Mercator and Ortelius edited several maps of Palestine's territory. Cartographers from several European countries edited more than 6,000 maps presenting the Biblical territories and Biblical events. Modem maps, based on detailed topographical surveys, were edited m the second half of the 19* and 20th centuries. W artykule przedstawiono kolejne etapy rozwoju geoinformacji dotycz?cej terenówr biblijnych. Omówiono dwa ?ród?a informacji, a mianowicie geoinformacje biblijne i pozabiblijne. W tekstach biblijnych mo?na znale?? wiele, cz?sto bardzo detalicznych informacji topograficznych. Najstarsze ?ród?a pozabiblijne, to staro?ytne dokumenty odnalezione na terenach Egiptu i Mezopotamii. Niektóre z nich pochodz? z trzeciego milenium przed Chr. Kolejnym etapem geoinformacji by?y onomastikony oraz dzienniki podró?y pisane przez podró?ników i pielgrzymów do Ziemi ?wi?tej. Do najbardziej znanych nale?y onomastikon sporz?dzony przez biskupa Euzebiusza z Cezarei oraz onomastikon ?w. Hieronima. Do jed- nych z najstarszych map Palestyny nale?y mozaikowa mapa odnaleziona na posadzce ko?cio?a w Madabie pochodz?ca z roku 565. Szybki rozwój kartografii biblijnej nast?pi? w wieku XVI i XVI. kiedy to s?ynni kartografowie Mercator i Ortelius opracowali wiele map Palestyny. Kartografowie z wielu krajów Europy, w ci?gu minionych stuleci, opracowali ponad 6 tysi?cy map biblijnych przedstawiaj?cych terytoria i wydarzenia biblijne.

The Crystal Structure of a Coxsackievirus B3-RD Variant and a Refined 9-Angstrom Cryo-Electron Microscopy Reconstruction of the Virus Complexed with Decay-Accelerating Factor (DAF) Provide a New Footprint of DAF on the Virus Surface  

PubMed Central

The coxsackievirus-adenovirus receptor (CAR) and decay-accelerating factor (DAF) have been identified as cellular receptors for coxsackievirus B3 (CVB3). The first described DAF-binding isolate was obtained during passage of the prototype strain, Nancy, on rhabdomyosarcoma (RD) cells, which express DAF but very little CAR. Here, the structure of the resulting variant, CVB3-RD, has been solved by X-ray crystallography to 2.74 ?, and a cryo-electron microscopy reconstruction of CVB3-RD complexed with DAF has been refined to 9.0 ?. This new high-resolution structure permits us to correct an error in our previous view of DAF-virus interactions, providing a new footprint of DAF that bridges two adjacent protomers. The contact sites between the virus and DAF clearly encompass CVB3-RD residues recently shown to be required for binding to DAF; these residues interact with DAF short consensus repeat 2 (SCR2), which is known to be essential for virus binding. Based on the new structure, the mode of the DAF interaction with CVB3 differs significantly from the mode reported previously for DAF binding to echoviruses.

Ethical marketing in 'aesthetic' ('esthetic') or'cosmetic dentistry'. Part 3.  

PubMed

This, the third and final article in this series on ethical marketing, makes it clear that cosmetic dentistry is not a guaranteed one-way ticket to happiness for either patients or dentists, but it can be for lawyers. In fact, this area of dentistry is fraught with many dangers for the unwary patient and even for the enthusiastic or experienced dentist. In general, it is not at all wise to raise patient expectations beyond that which is definitely going to be easily achievable in his/her particular case. Clinical Relevance: If things go wrong with extensive cosmetic dentistry, or are judged as being suboptimal, or unacceptable, by the patient, then that dentist may become liable for all the remakes of that elective cosmetic dentistry for the lifetime of the patient, together with all the associated general and specific damages. This is because, if the elective cosmetic dentistry had not been done, the patient would not have needed to have the remakes. Informed consent is a major issue with cosmetic dentistry, as is avoiding any possible claims for breach of contract, which could be verbal, implied or written. PMID:23094568

[Lasers in dentistry. Part A--Development, characteristics, structure, principles of operation and types of lasers].  

PubMed

Laser technology is developing very quickly. New Lasers with a wide range of characteristics are available today and are being used in the various fields of dentistry. The search for new devices and technologies for dental procedures was always challenging and in the last two decades much experience and knowledge has been gained. The purpose of this series of articles published in the journal of the Israel Dental Association in three parts is to present the Israeli dentist a comprehensive and contemporary overview which will assist him in understanding the potential of the use of laser technology for clinical applications in dentistry. The first part will describe the history and development of lasers in dentistry, the characteristics and structure of lasers as well as their principles of operation. A description of the different types of lasers used today in dentistry will be presented in the first part. The second part will describe the interaction of lasers with biological tissues and their effect on the soft and hard tissues of the oral cavity as well as on the dental pulp. Laser safety in the dental practice will also be discussed.

Current aspects on bonding effectiveness and stability in adhesive dentistry.  

PubMed

Improved dental adhesive technology has extensively influenced modern concepts in restorative dentistry. In light of minimal-invasive dentistry, this new approach promotes a more conservative cavity design, which basically relies on the effectiveness of current enamel-dentine adhesives. Nowadays, the interaction of adhesives with the dental substrate is based on two different strategies, commonly described as an etch-and-rinse and a self-etch approach. In an attempt to simplify the bonding technique, manufacturers have decreased the number of steps necessary for the accomplishment of the bonding procedure. As a consequence, two-step etch-and-rinse and one-step (self-etch) adhesives were introduced and gained rapid popularity in the dental market due to their claimed user-friendliness and lower technique sensitivity. However, many concerns have been raised on the bonding effectiveness of these simplified adhesives, especially in terms of durability, although this tends to be very material dependent. In order to blend all the adhesive components into one single solution, one-step adhesives were made more acidic and hydrophilic. Unfortunately, these properties induce a wide variety of seemingly unrelated problems that may jeopardize the effectiveness and stability of adhesion to the dental substrate. Being more susceptible to water sorption and thus nanoleakage, these adhesives are more prone to bond degradation and tend to fail prematurely as compared to their multi-step counterparts. Incidentally, another factor that may interfere with the bonding effectiveness of adhesives is the technique used for caries removal and cavity preparation. Several tools are on the market today to effectively remove carious tissue, thereby respecting the current trend of minimum intervention. Despite their promising performance, such techniques modify the tooth substrate in different aspects, possibly affecting bonding effectiveness. Altogether, we may conclude that not only the adhesive formulation, but also substrate nature must be taken into account to achieve a stable bonding interface, rendering the restorative treatment more predictable in terms of clinical performance. In this review, we analyse the current theoretical and clinical aspects of adhesion to enamel and dentine, and discuss the diverse possibilities to overcome problems which nowadays still challenge clinicians in their achievement of a more stable and effective bond to tooth enamel and dentine.

Formaldehyde in dentistry: a review of mutagenic and carcinogenic potential  

SciTech Connect

For many years there has been controversy over the value of antimicrobial drugs for intracanal dressings in endodontics. Formocresol, a formaldehyde compound, has evolved as the preferred drug for routine endodontic procedures, as well as pediatric endodontics. The increase in the use of formaldehyde has been complicated by the introduction of paraformaldehyde pastes for filling root canals. Neither of these formulas has ever been standardized. The doses are arbitrary, and the common dose of formocresol has been shown to be many times greater than the minimum dose needed for effect. The efficacy of paraformaldehyde pastes is questionable and remains clouded by inconclusive evidence, conflicting research, inadequate terminology, and a lack of convincing statistical evidence. The clinical use and delivery of formocresol and paraformaldehyde pastes remain arbitrary and unscientific. Formaldehyde has a known toxic mutagenic and carcinogenic potential. Many investigations have been conducted to measure the risk of exposure to formaldehyde; it is clear that formaldehyde poses a carcinogenic risk in humans. There is a need to reevaluate the rationale underlying the use of formaldehyde in dentistry particularly in light of its deleterious effects.

Sound levels in conservative dentistry and endodontics clinic  

PubMed Central

Aim: To evaluate the sound levels generated in dental clinics of conservative dentistry and endodontics. Material and Methods: A decibel-meter with digital readout was used to measure sound levels at different time intervals at the chairside and at the center of the clinic. Minimum and maximum readings during a 3 min interval were recorded. Results: In the post-graduate (PG) clinic, there was significant difference in noise levels between the chairside (66-81 dB[A]) and the center of the clinic (66-67 dB[A]) at certain times. In the under graduate (UG) clinic, noise levels with suction and either high/slow speed handpieces (67-80 dB[A]) were significantly higher than the center of clinic. Suction alone in the UG clinic (63-75 dB[A]) was significantly quieter than in the PG clinic (69-79 dB[A]). Conclusions: (1) Mean sound levels in the working clinics ranged from 63.0 dB[A] to 81.5 dB[A]. These are within the recommended range for dental equipment. (2) With suction and either low/high speed handpiece combination, the PG clinic was significantly noisier than the UG clinic at several time periods.

Practical aspects of DNA-based forensic studies in dentistry  

PubMed Central

Forensic dentistry as a science has evolved from simple methods of age estimation and bite-mark analysis, to a new era of genetic and serological investigations. DNA analysis in forensic science requires a sample or source from either an individual (living or dead) or a crime/incident site. The orofacial region is a good source of such material, due to the fact that certain oral tissues are relatively resistant to environmental degradation and destruction by thermal, electrical, and mechanical insult. Dentists may be called upon to provide samples and expert analysis in many such situations. Sources include soft and hard tissues of teeth and jaws, saliva, biopsy material, and mucosal swabs. Tissue samples should be handled with care, and correct protocol in collection and preparation has to be followed. This ensures a high yield of the required DNA. Hard tissues like teeth require specialized procedures to extract the genetic material. Research has shown that there is a wide variation in the quality and quantity of DNA extracted from different individuals from the same site even under similar conditions. This necessitates calibration of the various methods to achieve best results. DNA analysis can provide highly accurate identification if used correctly. Here a description of the various sources in the oral region has been provided from which samples could be forwarded to the forensic laboratory. Most commonly employed techniques of collection and handling for laboratory procedures have been outlined.

Cavitation bubbles induced by Erbium lasers: implications for dentistry  

NASA Astrophysics Data System (ADS)

With new fiber systems available for 3 ?m, Erbium lasers become more interesting for precise tissue ablation in a water environment enabling new application in e.g. dentistry. The dynamics of explosive bubble formation was investigated at 2.78 ?m (Er,Cr;YSGG) and 2.94 ?m (Er:YAG), in relation to energy (10-50 mJ), pulse length (20-150 ?s) and fiber tip shape (flat or taper). The dynamics of exploding and imploding vapor bubbles were captured with high speed imaging (10 - 300 ?s range). Increasing the pulse length and energy, the vapor bubble became more elongated with an opaque surface for flat tip fibers. Tapered fibers produced spherical vapor bubbles with an optically transparent surface expected to be more forceful for creating mechanical effects in both hard and soft tissues. There was no significant difference between bubbles formed at 2.78 ?m (Er,Cr;YSGG) and 2.94 ?m (Er:YAG).

PubMed Central

Compared to adult medicine, drug use in children is not extensively researched. Objective: The objective of present study is to find out drug prescribing pattern in the Department of Pedodontics and Preventive Dentistry and Orthodontics in teaching hospitals in Rajasthan, India. Methods: A prospective study was conducted in June 2011. A total of 619 prescriptions were collected randomly. Prescribing pattern was analyzed using WHO basic drug indicator. Results: The average number of drugs and antimicrobial agent prescribed per prescription were 2.24 and 0.81 respectively. Antimicrobial agent contained 81.74% of all prescriptions. Most common groups of drugs prescribed by pedodontist were NSAIDS & Antipyretics (37.7%), Antimicrobial (36.4%) and Vitamins (12.3%). Prophylactic use of antimicrobial agents was 5.5 ± 0.5 days. Fixed dose combination (45.6%) frequently used by brand name. twelve percent generic drugs were used. Most of the drugs were from Essential Drug List especially a only one drug was prescribed. Conclusion: There is a need of mass awareness amongst dentists about good prescribing habit. Every institution must have Drugs and Therapeutic Committees. The five steps of WHO Program on Rational Use of Drugs (RUD) should be followed for rational prescribing of drugs.

[Bioethical analysis of the Brazilian Dentistry Code of Ethics].  

PubMed

The Brazilian Dentistry Code of Ethics (DCE), Resolution CFO-71 from May 2006, is an instrument created to guide dentists' behavior in relation to the ethical aspects of professional practice. The purpose of the study is to analyze the above mentioned code comparing the deontological and bioethical focuses. In order to do so, an interpretative analysis of the code and of twelve selected texts was made. Six of the texts were about bioethics and six on deontology, and the analysis was made through the methodological classification of the context units, textual paragraphs and items from the code in the following categories: the referentials of bioethical principlism--autonomy, beneficence, nonmaleficence and justice -, technical aspects and moral virtues related to the profession. Together the four principles represented 22.9%, 39.8% and 54.2% of the content of the DCE, of the deontological texts and of the bioethical texts respectively. In the DCE, 42% of the items referred to virtues, 40.2% were associated to technical aspects and just 22.9% referred to principles. The virtues related to the professionals and the technical aspects together amounted to 70.1% of the code. Instead of focusing on the patient as the subject of the process of oral health care, the DCE focuses on the professional, and it is predominantly turned to legalistic and corporate aspects.

Amorphous calcium phosphate and its application in dentistry  

PubMed Central

Amorphous Calcium Phosphate (ACP) is an essential mineral phase formed in mineralized tissues and the first commercial product as artificial hydroxyapatite. ACP is unique among all forms of calcium phosphates in that it lacks long-range, periodic atomic scale order of crystalline calcium phosphates. The X-ray diffraction pattern is broad and diffuse with a maximum at 25 degree 2 theta, and no other different features compared with well-crystallized hydroxyapatite. Under electron microscopy, its morphological form is shown as small spheroidal particles in the scale of tenths nanometer. In aqueous media, ACP is easily transformed into crystalline phases such as octacalcium phosphate and apatite due to the growing of microcrystalline. It has been demonstrated that ACP has better osteoconductivity and biodegradability than tricalcium phosphate and hydroxyapatite in vivo. Moreover, it can increase alkaline phosphatase activities of mesoblasts, enhance cell proliferation and promote cell adhesion. The unique role of ACP during the formation of mineralized tissues makes it a promising candidate material for tissue repair and regeneration. ACP may also be a potential remineralizing agent in dental applications. Recently developed ACP-filled bioactive composites are believed to be effective anti-demineralizing/remineralizing agents for the preservation and repair of tooth structures. This review provides an overview of the development, structure, chemical composition, morphological characterization, phase transformation and biomedical application of ACP in dentistry.

Minimal Intervention Dentistry (MID) for managing dental caries - a review  

PubMed Central

This publication describes the history of Minimal Intervention Dentistry (MID) for managing dental caries and presents evidence for various carious lesion detection devices, for preventive measures, for restorative and non-restorative therapies as well as for repairing rather than replacing defective restorations. It is a follow-up to the FDI World Dental Federation publication on MID, of 2000. The dental profession currently is faced with an enormous task of how to manage the high burden of consequences of the caries process amongst the world population. If it is to manage carious lesion development and its progression, it should move away from the ‘surgical’ care approach and fully embrace the MID approach. The chance for MID to be successful is thought to be increased tremendously if dental caries is not considered an infectious but instead a behavioural disease with a bacterial component. Controlling the two main carious lesion development related behaviours, i.e. intake and frequency of fermentable sugars, to not more than five times daily and removing/disturbing dental plaque from all tooth surfaces using an effective fluoridated toothpaste twice daily, are the ingredients for reducing the burden of dental caries in many communities in the world. FDI’s policy of reducing the need for restorative therapy by placing an even greater emphasis on caries prevention than is currently done, is therefore, worth pursuing.

[Brazilian bibliographical output on public oral health in public health and dentistry journals].  

PubMed

The scope of this paper is to describe characteristics of the scientific output in the area of public oral health in journals on public health and dentistry nationwide. The Scopus database of abstracts and quotations was used and eight journals in public health, as well as ten in dentistry, dating from 1947 to 2011 were selected. A research strategy using key words regarding oral health in public health and key words about public health in dentistry was used to locate articles. The themes selected were based on the frequency of key words. Of the total number of articles, 4.7% (n = 642) were found in oral health journals and 6.8% (n = 245) in public health journals. Among the authors who published most, only 12% published in both fields. There was a percentile growth of public oral health publications in dentistry journals, though not in public health journals. In dentistry, only studies indexed as being on the topic of epidemiology showed an increase. In the area of public health, planning was predominant in all the phases studied. Research to evaluate the impact of research and postgraduate policies in scientific production is required. PMID:24897491

The era of whiter teeth: advertising in American dentistry 1910-1950.  

PubMed

It has often been argued that the public image of dentists has been tainted by association with fear and pain into an image of evil 'psychodontists' and that there is an apparent lack of 'role models' in popular film, television, art and literature concerned with dentistry. This paper argues that we get a different picture when looking at different media. Advertisements introduce into a public domain, positive images of dentistry which crucially differ from the images found in other popular media. This paper traces the public image of dentistry in early 20th-century America, as seen through dentifrice advertisements, and suggests three important reasons for studying advertisements: First, advertisements provide a supplement to studies of popular images of dentistry carried out so far. Second, advertisements have played an important part in advancing oral hygiene as a public concern. And third, advertisements provide the historian of dentistry with a unique opportunity for analyzing the complex and interwoven relationship of popular and professional discourses, since ads have acted as catalysts for professional discussions and self-reflection among dentists.

EDITORIAL: Papers from the 3rd International SiGe Technology and Device Meeting (Princeton, New Jersey, USA, 15 17 May 2006) (ISTDM 2006)  

NASA Astrophysics Data System (ADS)

Silicon germanium (SiGe) technology is the driving force behind the explosion in low-cost, lightweight, personal communications devices such as digital wireless handsets, as well as other entertainment and information technologies such as digital set-top boxes, direct broadcast satellites (DBS), automobile collision avoidance systems, and personal digital assistants. Low power SiGe circuits extend the life of wireless phone batteries and allow smaller and more durable communication systems. The first paper on SiGe can be traced back to 1955 with work on the magnetoresistance of silicon germanium alloys [1]. The first mention of a SiGe device was actually in the original patent for the bipolar transistor where the idea of a SiGe heterojunction bipolar transistor (HBT) was discussed with a description of the physics in the 1950s [2]. Such a transistor required the epitaxial growth of Si/SiGe heterostructures and this was not demonstrated until 1975 by Kasper, Herzog and Kibbel at the then AEG Research Centre (now Daimler Chrysler) in Ulm, Germany using molecular beam epitaxy [3]. The late 1980s and 1990s saw significant improvements in the growth technique of mismatched SiGe epitaxial films, enabling SiGe devices to become a practical reality. Through this early work, silicon germanium has moved from the research laboratory to industrial production accounting for a significant percentage of manufactured semiconductor devices. Silicon germanium epitaxy has enabled the use of strained-layer silicon channels in transistors, an industry standard. Although the bulk of the new products based on SiGe are logic and amplifier type integrated circuits, the scope of SiGe is wider. Today, a surprising amount of research is being associated with such areas as opto, MEMs and nanotechnology for detectors, solar cells, laser diodes and radar systems. It is estimated that in 2006 the SiGe industry will generate $717.6 M. The papers published here represent a subset of those presented at the 3rd International SiGe Technology and Device Meeting held in Princeton from 15 to 17 May 2006. This conference followed on from two highly successful meetings held at Nagoya University in 2003 and in Frankfurt in 2004. The topics of the ISTDM 2006 conference included SiGe and other group IV materials such as SiGe:C and their selective growth, process technologies such as diffusion control and gate dielectrics, device issues regarding bipolar and field effect transistors and optical devices, circuits for logic communication and mixed signals, and applications such as wireless, imaging, sensing and radar. The organizers of the conference were pleased to present two plenary talks (Gary Patton of IBM and Lionel Kimerling of MIT) on SiGe developments and 19 invited talks during the three days, along with 53 short contributions and 46 posters presentations. These talks showed that there is a thriving academic and industrial research community in this field. The papers in this issue cover important areas that are currently under intense development: strained Si FETs and CMOS, HBT devices and circuits, germanium devices, optoelectronics, quantum devices, selective epitaxy and patterned structures, heterostructure growth, novel characterization, novel structures, process technology, and virtual and engineered substrates. We hope that the readers of this issue will find these papers to be interesting, informative, and useful as overviews on the best and latest developments in this vibrant, evolving technology.

Cross-contamination potential of saliva ejectors used in dentistry.  

PubMed

It has been postulated that evacuation systems used in dentistry could be a source of cross-contamination between patients through backflow of bacteria dislodged from the saliva ejector tubings. The bacterial microflora associated with these systems was characterized using transmission electron microscopy (TEM) and microbiological cultures. The potential for backflow was investigated by a study of pressure differentials in evacuation system tubing and by the presence of bacteria in backflow samples. Evacuation lines were coated with microbial biofilms in which microcolonies of Gram-positive cocci and Gram-negative bacilli predominated, embedded in an extensive polysaccharide matrix. Most bacteria were metabolically active. Occasionally, buccal material such as collagen, fibrin and eukaryotic cell debris was observed. In other experiments, flow reversal was detected several times during saliva ejector use though each of these events was brief (less than 0.1 s). Aspiration of saliva, or occlusion of the mouthpiece opening by the oral mucosa, were the major factors leading to backflow episodes. Bacteria associated with backflow were found in almost 25% assays, with counts ranging from 1-300 cfu/occurrence. The majority of the bacteria isolated from biofilm or backflow samples were staphylococci, micrococci and non-fermentive Gram-negative rods. Pathogens such as Pseudomonas aeruginosa and Staphylococcus aureus were also isolated from backflow fluids. No oral streptococci could be recovered from biofilms in the tubing beyond 15 min from the last saliva ejector use however, suggesting that these species did not survive in the biofilms. These data suggest, although without direct proof of cross-contamination, the possible existence of an infectious risk associated with oral evacuation systems, as potential pathogens may be shed from tubing biofilms following backflow. Even if the risk of cross-contamination between patients is considered to be low, the necessity for regular disinfection of these systems must be stressed, since biofilms can serve as a reservoir for pathogens or harbor potentially infectious material.

Canadian EdGEO National Workshop Program  

NASA Astrophysics Data System (ADS)

Established in the early 1970s, EdGEO supports locally driven geosciences workshops for Canadian teachers. Workshops are organized by geoscientists and teachers, and typically have field, laboratory and classroom components. Grants of up to $3000 per workshop are available from the National EdGEO Program. By providing educational opportunities for today's teachers and, through them, their students, EdGEO seeks to cultivate a heightened awareness of our planet. EdGEO workshops provide teachers with potential fieldtrip sites for their students and the knowledge, enthusiasm and materials to inspire their students to engage in geoscience. Networking opportunities with local experts promote the importance of the geoscience profession. The expected result is an improved capacity on the part of Canadians to understand the Earth and to make informed decisions, especially with regard to the use of mineral and energy resources, the maintenance and remediation of the environment, and response to geological hazards. There exists a critical need to provide teachers with training and resources to tackle their Earth science curricula. In 2008, EdGEO supported fourteen workshops, with an unprecedented 521 teachers attending. These teachers then used our resources to reach an estimated 14,000 students during that single academic year. EdGEO workshops are locally driven and are therefore very diverse. Workshops are strongly tied to the provincial curriculum, focus on a specific geoscience topic, or may be largely field-based to demonstrate and practice how field activities could be incorporated into Earth science teaching. Many strive to include all of these important components. Geoscientists and teachers work collaboratively to develop and deliver EdGEO workshops to ensure that the activities can be effectively used in the classroom. The length of these professional development opportunities range from two-hour sessions to several days, and can generally accommodate up to twenty-five teachers. Workshops have been presented at teachers' conferences, province-wide professional development days, industry events, and independently. Participants consistently rate EdGEO workshops as excellent and outstanding. Responses on the evaluation forms suggest that teachers value the hands-on aspect of the workshops, the strong connection to the curriculum, the classroom resources provided, the field components, the collaborations forged between teachers and geoscientists, and the knowledge gained. Comments also continually make reference to the talented experts who enthusiastically commit to sharing their expertise in geoscience. The ability of EdGEO to advance its vital mission relies on the generous support of scientific associations, corporations, foundations and individuals. With increased funding, EdGEO's future will see the expansion of partnerships with Faculties of Education across Canada. These faculties offer an opportunity to reach out to aspiring teachers before they enter the classroom. Future plans include the compilation of EdGEO lesson plans from coast to coast. These valuable resources would connect to provincial curriculum, provide an opportunity to wedge Earth science into other science subjects, and serve as the basis for developing a series of standardized workshops to be implemented across the nation.

[Anti-hepatitis B surface antigen titres in vaccinated dentistry students at Damascus University].  

PubMed

Dental practice carries considerable danger for acquiring bloodborne pathogens such as hepatitis B virus (HBV). Vaccination against this virus is an important approach to reducing the infection. Post-vaccination test to confirm the seroconversion is important also. Over the period 1 March-31 May 2010, we assessed the efficacy of HBV vaccination among 91 fourth-year dental students at Damascus University, who were vaccinated under the mandatory Faculty of Dentistry programme. Anti-HBsAg antibody titres were determined in the blood samples using an enzyme immunoassay to measure; > or = 10 IU/mm was considered an adequate response titer. Seven of the 91 dentistry students (7.7%) had anti-HBs antibody titre < 10 mlU/mL. The frequency of unresponsiveness was significantly higherwith smoking (P = 0.012) and alcohol consumption (P = 0.014). Anti-HBs test should be included in routine immunization services of the School of Dentistry at Damascus University. PMID:22888621

Risk factors for ED use among homeless veterans.  

PubMed

Despite national concern about homeless veterans, there has been little examination of their use of emergency department (ED) services. This study examines factors related to the use of ED services in the Veterans Affairs (VA) healthcare system, where insurance is not a barrier to ambulatory healthcare. National VA administrative data from fiscal year 2010 are used to describe the proportions of ED users among homeless and domiciled VA patients. A case-control design is then used to compare homeless ED and non-ED users on sociodemographic and clinical correlates, as well as use of ambulatory care and psychotropic medications. Sixteen percent of domiciled VA patients used EDs at least once during the year and 1% were frequent ED users (>4 ED visits) compared to 45% of homeless VA patients, 10% who were frequent ED users. Among homeless VA patients, those who used EDs were more likely to have a range of psychiatric and medical conditions, and had more service visits and psychotropic medication prescriptions than non-ED users. Multivariate analyses suggest their risk for psychiatric and medical conditions increase their likelihood of using ED services. The high rate of ED use among homeless veterans is associated with significant morbidity, but also greater use of ambulatory care and psychotropics suggesting their ED use may reflect unmet psychosocial needs.

Titanium in dentistry: historical development, state of the art and future perspectives.  

PubMed

Titanium is a metallic element known by several attractive characteristics, such as biocompatibility, excellent corrosion resistance and high mechanical resistance. It is widely used in Dentistry, with high success rates, providing a favorable biological response when in contact with live tissues. Therefore, the objective of this study was to describe the different uses of titanium in Dentistry, reviewing its historical development and discoursing about its state of art and future perspective of its utilization. A search in the MEDLINE/PubMed database was performed using the terms 'titanium', 'dentistry' and 'implants'. The title and abstract of articles were read, and after this first screening 20 articles were selected and their full-texts were downloaded. Additional text books and manual search of reference lists within selected articles were included. Correlated literature showed that titanium is the most used metal in Implantology for manufacturing osseointegrated implants and their systems, with a totally consolidated utilization. Moreover, titanium can be also employed in prosthodontics to obtain frameworks. However, problems related to its machining, casting, welding and ceramic application for dental prosthesis are still limiting its use. In Endodontics, titanium has been used in association to nickel for manufacturing rotatory instruments, providing a higher resistance to deformation. However, although the different possibilities of using titanium in modern Dentistry, its use for prostheses frameworks still needs technological improvements in order to surpass its limitations.

UK National Clinical Guidelines in Paediatric Dentistry: stainless steel preformed crowns for primary molars.  

PubMed

This revised Clinical Guideline in Paediatric Dentistry replaces the previously published sixth guideline (Fayle SA. Int J Paediatr Dent 1999; 9: 311-314). The process of guideline production began in 1994, resulting in first publication in 1997. Each guideline has been circulated widely for consultation to all UK consultants in paediatric dentistry, council members of the British Society of Paediatric Dentistry (BSPD), and to people of related specialities recognized to have expertise in the subject. The final version of this guideline is produced from a combination of this input and thorough review of the published literature. The intention is to encourage improvement in clinical practice and to stimulate research and clinical audit in areas where scientific evidence is inadequate. Evidence underlying recommendations is scored according to the SIGN classification and guidelines should be read in this context. Further details regarding the process of paediatric dentistry guideline production in the UK is described in the Int J Paediatr Dent 1997; 7: 267-268. PMID:18808544

Cytoplasmic Streaming - Skylab Student Experiment ED-63  

NASA Technical Reports Server (NTRS)

This chart describes the Skylab student experiment (ED-63), Cytoplasmic Streaming, proposed by Cheryl A. Peitz of Arapahoe High School, Littleton, Colorado. Experiment ED-63 was to observe the effect of zero-gravity on cytoplasmic streaming in the aquatic plant named Elodea, commonly called water weed or water thyme. The phenomenon of cytoplasmic streaming is not well understood, but it is recognized as the circulation mechanism of the internal materials or cytoplasm of a cell. Cytoplasm is a gelatinous substance that has the ability to change its viscosity and flow, carrying various cell materials with it. The activity can be stimulated by sunlight or heat. In March 1972, NASA and the National Science Teachers Association selected 25 experiment proposals for flight on Skylab. Science advisors from the Marshall Space Flight Center aided and assisted the students in developing the proposals for flight on Skylab.

EDS analysis of bromine in polymers  

SciTech Connect

Design requirements for the Inertial Confinement Fusion program at LLNL frequently require polymers to be modified with known amounts of dopants without seriously degrading the surface finish. Techniques such as x-ray fluorescence permit reliable quantitative analyses of the dopants. However, our strong emphasis on surface finish requires frequent SEM examinations, and the need for rapid analyses instigated on evaluation of EDS to analyze bromine in the SEM. Brominated polymers based on polystyrene and a plasma-deposited hydrocarbon with a composition of approximately CH{sub 1.2} were analyzed. The analyses were performed using an optional thin window in a NORAN Micro-Z 2 Si(Li) EDS mounted on a Hitachi S-800 FESEM. The specimens were coated with palladium. Since the standard ZAF programs are ineffective for hydrocarbon-based materials, calibration curves were established using Br L{sub {alpha}}/C K{sub {alpha}} peak ratios. A cryogenic vacuum system on the FESEM significantly reduced detrimental effects of carbon contamination on the sensitivity of the C K{sub {alpha}} peak. Brominated polymers are susceptible to electron-beam damage, so the extent of damage and its effect on the EDS analysis also had to be determined. 3 figs.

Intraoral Laser Welding (ILW) in Implant Prosthetic Dentistry: Case Report  

PubMed Central

The aim of this clinical study was to describe the possibility of using the Nd:YAG laser device utilized in the dental offices to weld metals intraorally. The authors, before applying this technique “in vivo” on human subjects, tested the “in vitro” metal welding efficacy of dental Nd:YAG device firstly by interferometry, SEM, and EDS and subsequently by thermal camera and thermocouples in order to record temperature changes during the welding process on bovine jaws. Four implants were inserted in the edentulous maxillary arch of a 67 years old male patient. Immediately after that, a bar previously made by the dental technician was intraorally welded to the abutments by Nd:YAG laser (Fidelis Plus III, Fotona, Slovenia) with these parameters: 9.90?mJ, 1?Hz, 15?msec, 0.6?mm spot. Then the prosthesis was connected to the bar with four OT Caps. This clinical study, even if preliminary, suggests that laser welding technique may be intraorally used without side effects.

EDS coal liquefaction process development. Phase V. EDS Consolidation Program: flushing and blowdown system design  

SciTech Connect

The flushing and blowdown system of an EDS plant provides the means of removing viscous coal products and slurry streams from plant vessels and lines. In addition, it provides the flushing oil needed during normal operations for purging instruments in slurry service, for flushing slurry pump and slurry agitator seals, and for flushing slurry safety valve inlet lines. It contains a blowdown system for collecting material from washing operations, including the transport of the collected material to slop tankage. The rerun options for depleting the inventory of collected slop are a related aspect of the flushing and blowdown system design although specific equipment for handling slop is not part of the flushing and blowdown system facilities. This report documents the results of a study which evaluates the flushing and blowdown requirements for a commercial-scale EDS plant. The work was conducted as part of the EDS Consolidation Program. The design recommendations represent a consolidation of learnings accrued during previous phases of the EDS Project including results obtained from ECLP operations, from the ECLP Test Program, and from past EDS Study Design preparations. 1 reference, 4 figures, 2 tables.

Passive damping in EDS maglev systems.  

SciTech Connect

There continues to be strong interest in the subjects of damping and drag forces associated with electrodynamic suspension (EDS) systems. While electromagnetic drag forces resist the forward motion of a vehicle and therefore consume energy, damping forces control, at least in part, the response of the vehicle to disturbances. Ideally, one would like to reduce the drag forces as much as possible while retaining adequate damping forces to insure dynamic stability and satisfactory ride quality. These two goals turn out to be difficult to achieve in practice. It is well known that maglev systems tend to be intrinsically under damped. Consequently it is often necessary in a practical system design to enhance the damping passively or actively. For reasons of cost and simplicity, it is desirable to rely as much as possible on passive damping mechanisms. In this paper, rough estimates are made of the passive damping and drag forces caused by various mechanisms in EDS systems. No attention will be given to active control systems or secondary suspension systems which are obvious ways to augment passive damping mechanisms if the latter prove to be inadequate.

Medical-grade calcium sulfate has been successfully used for several decades as a bone filler and as a carrier with medications or bone growth factors for the treatment of bone defects. The present review illustrates the biological behavior and clinical outcomes of this material when used in clinical implant dentistry. Furthermore, the review illustrates the different indications specifically related to implant dentistry when medical-grade calcium sulfate has been used alone or in combination with bone grafting materials. The histological published evidence is reviewed together with successful clinical results. This material, well known since the 1800's, continues to be used by clinicians and researchers worldwide, and the latest scientific evidence clearly indicates that medical-grade calcium sulfate can be used alone or in combination with biologically active proteins in applications such as socket preservation, ridge augmentation, and sinus lift procedures.

Markov models are mathematical models that can be used to describe disease progression and evaluate the cost-effectiveness of medical interventions. Markov models allow projecting clinical and economic outcomes into the future and are therefore frequently used to estimate long-term outcomes of medical interventions. The purpose of this paper is to demonstrate its use in dentistry, using the example of resin-bonded bridges to replace missing teeth, and to review the literature. We used literature data and a four-state Markov model to project long-term outcomes of resin-bonded bridges over a time horizon of 60 years. In addition, the literature was searched in PubMed Medline for research articles on the application of Markov models in dentistry. PMID:23186403

Cold Atmospheric Plasma: methods of production and application in dentistry and oncology  

PubMed Central

Cold Atmospheric Plasma is an ionized gas that has recently been extensively studied by researchers as a possible therapy in dentistry and oncology. Several different gases can be used to produce Cold Atmospheric Plasma such as Helium, Argon, Nitrogen, Heliox, and air. There are many methods of production by which cold atmospheric plasma is created. Each unique method can be used in different biomedical areas. In dentistry, researchers have mostly investigated the antimicrobial effects produced by plasma as a means to remove dental biofilms and eradicate oral pathogens. It has been shown that reactive oxidative species, charged particles, and UV photons play the main role. Cold Atmospheric Plasma has also found a minor, but important role in tooth whitening and composite restoration. Furthermore, it has been demonstrated that Cold Atmospheric Plasma induces apoptosis, necrosis, cell detachment, and senescence by disrupting the S phase of cell replication in tumor cells. This unique finding opens up its potential therapy in oncology.

Ozone has been successfully used in medical field since many years owing to its oxidizing property making it an excellent antimicrobial agent. Moreover its potent anti-inflammatory property along with favorable cellular and humoral immune response made ozone an effective therapeutic agent. Also its ability to arrest and reverse carious lesions in a predictable way opened up a new chapter in minimal intervention dentistry. Furthermore its efficacy in curbing resistant poly microbial root canal flora appears very promising.

Estrogenicity of resin-based composites and sealants used in dentistry.  

PubMed

We tested some resin-based composites used in dentistry for their estrogenic activity. A sealant based on bisphenol-A diglycidylether methacrylate (bis-GMA) increased cell yields, progesterone receptor expression, and pS2 secretion in human estrogen-target, serum-sensitive MCF7 breast cancer cells. Estrogenicity was due to bisphenol-A and bisphenol-A dimethacrylate, monomers found in the base paste of the dental sealant and identified by mass spectrometry. Samples of saliva from 18 subjects treated with 50 mg of a bis-GMA-based sealant applied on their molars were collected 1 hr before and after treatment. Bisphenol-A (range 90-931 micrograms) was identified only in saliva collected during a 1-hr period after treatment. The use of bis-GMA-based resins in dentistry, and particularly the use of sealants in children, appears to contribute to human exposure to xenoestrogens. PMID:8919768

Teaching, learning, and assessment in geriatric dentistry: researching models of practice.  

PubMed

Changing demography due to the increasing population of elderly persons the world over has raised new challenges in every sphere of life. The greatest challenge is to provide affordable, accessible, and equitable health care to this population. Oral health is an integral part of general health and affects physical and mental well-being and quality of life of elderly persons. To provide quality oral health care to the elderly, it is important to focus on education in geriatric dentistry, since it is known that education is closely linked to health care provision. It has been found that education in geriatric dentistry has wide variations in different parts of the world. Also, it is being taught at different levels: the predoctoral curriculum, postdoctoral certificate/diploma courses of varying duration by direct or distance mode using computer-assisted learning, degree courses of three years' duration, or continuing education programs. This article attempts to study geriatric dentistry education in global perspective. It is discussed in three sections: 1) varying concepts and methods of teaching, learning, and assessment in dental education; 2) status of geriatric dental education in developed and developing countries with emphasis on the Indian scenario; and 3) challenges and opportunities in developing geriatric dental education.

Effects of EdU Labeling on Mesenchymal Stem Cells  

PubMed Central

Background Thymidine analog 5-ethynyl-2-deoxyuridine (EdU) has recently been employed for tracking mesenchymal stem cells (MSCs). In the present study we tested whether EdU was cytotoxic and whether it interfered with MSC’s differentiation, cytokine secretion, and migration. Methods EdU labeling was performed by incubating adipose-derived stem cells (ADSCs) with 10 ?M of EdU for 48 hours. Incorporation of EdU was detected by reaction with azide-conjugated Alexa594. The labeled and unlabeled ADSCs were compared for proliferation and apoptosis as determined by CellTiter and comet assays, respectively. They were also compared for neuron-like and endothelial differentiation as determined by morphology, marker expression, and function. Comparison of their secreted cytokine profile was performed by cytokine antibody array. Comparison of their response to homing factor SDF-1 was performed by migration assay. Results EdU was incorporated into the nucleus in approximately 70% of ADSCs. No significant differences in proliferation and apoptosis rates were observed between EdU-labeled and unlabeled ADSCs. Isobutylmethylxanthine (IBMX) induced both EdU-labeled and unlabeled ADSCs to assume a neuron-like morphology and to express ?-III tubulin. Endothelial growth medium-2 (EGM2) induced endothelial differentiation in both EdU-labeled and unlabeled ADSCs, including the ability to uptake low-density lipoprotein (LDL) and to form capillary-like structures as well as the expression of vWF, eNOS, and CD31. EdU-labeled and unlabeled ADSCs exhibited identical secreted cytokine profile and identical migratory response to SDF-1. Discussion At the recommended dosage of 10 ?M EdU is non-toxic to ADSCs. EdU label did not interfere with ADSC’s differentiation, cytokine secretion, or migratory response to SDF-1.

Dentistry - a professional contained career in healthcare. A qualitative study of Vocational Dental Practitioners' professional expectations  

PubMed Central

Background New graduates in the UK presently spend one year in training as Vocational Dental Practitioners (VDPs) in preparation for primary dental care. There is a growing recognition that the emerging workforce has very different professional expectations to those of earlier generations, with implications for the profession, patients and the performance of health systems. The objectives of this study were to investigate why VDPs' in England and Wales perceive they chose dentistry as a professional career; how they perceive their vision has changed and the implications for their professional career plans, both short- and longterm. Methods Purposive sampling of schemes was undertaken to include urban, rural and metropolitan schemes, schemes in areas with and without dental schools and geographic coverage across England and Wales. All VDPs in these schemes were initiated to participate in this qualitative study using focus groups. A topic guide was utilised to standardise data collection. Informants' views were recorded on tape and in field notes. Data were transcribed and analysed using Framework Methodology. Results A total of 99 VDPs participated in the 10 focus groups. Their choice of dentistry as a professional career was motivated by multiple categories of influence: 'academic', 'healthcare', 'lifestyle', the influence of 'family', 'friends', 'careers advice' and 'work experience'. Consideration of the features of the 'professional job' appears to have been key to their choice of dentistry and the 'active rejection of medicine' as an alternative career. Entry into the profession was proving a challenging process for some but not all VDPs. Informants perceived that their vision had been moderated as a result of 'personal student debt', 'national workforce initiatives', 'limitations on clinical practice' and the 'cost of additional training'. Short term goals focused around 'recovery from the past' and 'preparation for the future'. Longterm goals covered the spectrum of opportunities within dentistry. Factors influencing VDPs longterm career plans fell into six main categories: professional, personal, financial, political, social and cultural. Conclusion VDPs chose dentistry because they perceived that it provides a financially lucrative, contained career in healthcare, with professional status, job security and the opportunity to work flexibly. They perceive that their vision is challenged by changes affecting education and the healthcare system. Longterm professional expectations were closely linked with their personal lives and support a vision of a favourable work/life balance.

Presenting the 3rd edition of WRB  

NASA Astrophysics Data System (ADS)

The third edition of the international soil classification system "World Reference Base for Soil Resources" (WRB) will be presented during der 20th World Congress of Soil Science, Jeju, Korea, June 9-12. The second edition was published in 2006 and the first in 1998, which, in turn, was based on the Legends of the FAO Soil Map of the World. Now, after eight years of experience with the second edition, time was due for a revision. The major changes are: 1. The second edition had two different qualifier sequences for naming soils (IUSS Working Group WRB, 2006, update 2007) and for creating map legends (Guidelines for creating small-scale map legends using the WRB; IUSS Working Group WRB, 2010). The third edition has one sequence for both. The qualifiers for every Reference Soil Group are subdivided into a small number of main qualifiers that are ranked and a larger number of additional qualifiers that are not ranked and given in an alphabetical order. The name of a pedon must comprise all applying qualifiers. The name of a map unit comprises a specified small number of main qualifiers, depending on scale, whereas all other qualifiers are optional. 2. For some soils, problems have been reported. Albeluvisols are difficult to detect in the field and cover only small surfaces. They have been replaced by Retisols, which have a broader definition that is easier to identify in the field. 3. The use of some diagnostics was difficult. Examples are: The argic horizon had too low limit values, so we had much more soils with argic horizons than justified. The definitions of the cambic horizon and the gleyic and stagnic properties were not precise enough. Organic material, mollic and umbric horizons had an unnecessary complicated definition. 4. Some changes in the key to the Reference Soil Groups seemed to be justified. Fluvisols were moved further down, Durisols and Gypsisols switched their position, also Arenosols and Cambisols. The soils with an argic horizon were brought into a new sequence. 5. The umbrella function of WRB aims to allow the allocation of soil classes existing in a national classification system within the WRB. Characteristics that in a national system are regarded to be important must be considered in WRB - not necessarily at the highest level, but at least somewhere. The third edition of WRB allows a better accommodation of soil types, e.g., of the Australian and the Brazilian system. 6. Some environments or even ecoregions had not been well represented in WRB. The third edition allows a better accommodation of soils of ultra-continental permafrost regions, acid-sulphate soils and Technosols. 7. How to explain complicated sets of characteristics? For the third edition, efforts were made to give better structured definitions that can be more easily grasped. The editors of the third edition are convinced that the new WRB allows a more precise classification of soils including both, a better naming of pedons and a better elaboration of soil map legends.

Remote sensing investigation into the correlation between landslides caused by the 2002 November 3rd, 7.9M Denali Fault earthquake and a surge of the SE fork of McGinnis Peak Glacier.  

NASA Astrophysics Data System (ADS)

The 2002 November 3rd, 7.9 M Denali Fault caused a large landslide that deposited 11.4 x 106m3 feet of rock and ice onto the SE fork of McGinnis Peak Glacier. The landslide left a large mass on the upper ice reservoir of the glacier and blocked the terminus outlet of the glacier with debris. Satellite images and historic photos were used to examine the terminus history of the glacier. Further landslides/mass wasting events during the spring of 2003, documented via Land Sat 7 images, covered the same upper ice reservoir as the 2002 landslides. Between 2004 and 2006 the SE fork Glacier of McGinnis Peak experienced a dramatic surge. There is no known history of such dramatic surge occurrences on the glacier of interest. Though causation is difficult to prove preliminary evidence points towards the implication that the landslides generated by the 2002 earthquake most likely either caused or contributed to the documented glacial surge. Examination of more satellite images is planned to further examine McGinnis Peak's glacier history and to refine the timing of the possible correlation between the earthquake generated landslides and the dramatic surge of the SE glacial fork of McGinnis Peak

Assessing change in diet and biological affinity between the 4th and 3rd millennia cal BCE in the Portuguese Estremadura: a preliminary dental comparison of Feteira II and Bolores.  

PubMed

Although the social and political changes accompanying the transition from the Neolithic through Copper Age, between the 4th and 3rd millennia cal BCE, in southwestern Iberia are reasonably well understood, much less is known about whether population movements and dietary changes accompanied these transformations. To address this question, human dental remains from the Middle through Late Neolithic site of Feteira II (3600-2900 cal BCE) and the Late Neolithic site of Bolores (2800-2600 cal BCE) in the Portuguese Estremadura were used to examine diet (microwear) and affinity (dental non-metrics). Microwear features were not found to be significantly different between Feteira II and Bolores, suggesting that the emergence of social complexity during this period did not result in large-scale changes in subsistence practices during the period of use at these sites. Using the Arizona State University Dental Anthropology System and supporting statistics, no significant difference between the samples from Feteira II and Bolores was observed, suggesting that no population replacement occurred between the Middle Neolithic and Late Neolithic/Copper Age. However, at Bolores there is some indication that there may have been demographic exchanges between southern Iberian and North African populations during the Late Neolithic/Copper Age. PMID:24642202

Neutron Analysis - Skylab Student Experiment ED-76  

NASA Technical Reports Server (NTRS)

The rate of neutron flow is commonly referred to as a flux. The measurement of neutron fluxes in Skylab was the subject of a proposal by Terry Quist of San Antonio, Texas. This chart describes Quist's experiment, Neutron Analysis, Skylab student experiment ED-76. These measurements were considered important not only by NASA but also by the scientific community for four reasons. High energy neutrons can be harmful to human tissue if they are present in significant quantities. Fluxes of neutrons can damage film and other sensitive experimental equipment in a marner similar to those produced by x-rays or other radiation. Furthermore, neutron fluxes can be used as a calibration source for other space-oriented particle physics experiments. Finally, neutron fluxes can affect sensitive x-ray and gamma-ray astronomy observations. Quist's objectives were to measure the neutron fluxes present in Skylab and, with the assistance of NASA and other physicists, to attempt determination of their origin as well as their energy range or spectrum. This experiment had stimulated interest in further studies of neutron phenomena in space. In March 1972, NASA and the National Science Teachers Association selected 25 experiment proposals for flight on Skylab. Science advisors from the Marshall Space Flight Center aided and assisted the students in developing the proposals for flight on Skylab.

Web Formation - Skylab Student Experiment ED-52  

NASA Technical Reports Server (NTRS)

Judith S. Miles of Lexington High School, Lexington, Massachusetts, proposed skylab student experiment ED-52, Web Formation. This experiment was a study of a spider's behavior in a weightless environment. The geometrical structure of the web of the orb-weaving spider provides a good measure of the condition of its central nervous system. Since the spider senses its own weight to determine the required thickness of web material and uses both the wind and gravity to initiate construction of its web, the lack of gravitational force in Skylab provided a new and different stimulus to the spider's behavioral response. Two common cross spiders, Arabella and Anita, were used for the experiment aboard the Skylab-3 mission. After initial disoriented attempts, both spiders produced almost Earth-like webs once they had adapted to weightlessness. This photograph is of Arabella, a cross spider, in her initial attempt at spirning a web. This picture was taken by the crew of the Skylab 3 mission before Arabella adapted to her new environment.

The Anterior Ratio: The Missing Link between Orthodontics and Aesthetic Dentistry  

PubMed Central

There is an increase in the number of dentists using orthodontic treatment for anterior tooth alignment. This is either combined with additive bonding or interproximal reduction; knowing “when to” and “how much” requires an understanding of the anterior ratio. This case report explains how to use the anterior ratio to help provide optimal aesthetics and function for the ortho-restorative patient. The anterior ratio is an important diagnostic tool required for both disciplines of orthodontics and restorative dentistry which is often overlooked. The case report demonstrates the use of the Invisalign orthodontic appliance and the corresponding ClinCheck software to help achieve the proposed treatment goals.

The need for scientific evidence should be the basis of clinical practice. The field of restorative dentistry and endodontics is evolving at a rapid pace, with the introduction of several materials, instruments, and equipments. However, there is minimal information of their relevance in clinical practice. On the one hand, material and laboratory research is critical, however; its translation into clinical practice is not being substantiated enough with clinical research. This four part review series focuses on methods to improve evidence-based practice, by improving methods to integrate laboratory and clinical research.

Examining Whether Dental Therapists Constitute a Disruptive Innovation in US Dentistry  

PubMed Central

Dental therapists—midlevel dental providers who are roughly analogous to nurse practitioners in medicine—might constitute a disruptive innovation within US dentistry. Proponents tend to claim that dental therapists will provide more equitable access to dental care; opponents tend to view them from a perspective that focuses on retaining the current attributes of the dental profession. Therapists display traits similar to those of disruptive innovations: their attributes are different from dentists’, they may not initially be valued by current dental patients, they may appeal to current dental underutilizers, and they may transform the dental delivery system. Whether dental therapists constitute a disruptive innovation will only be determined retrospectively.

A prehistoric Native American mandible from a Fremont site (circa AD 1025) in Colorado has a conical pit in the worn occlusal surface of the lower right canine. Natural causes for this modification are ruled out by the presence of internal striae, a finding confirmed by experimental replication. The canine was artificially drilled before the individual's death and is associated with a periapical abscess. This is one of a very few examples of prehistoric dentistry in the world, and the first from the American Southwest. PMID:9261503

Neural tube defects are common congenital malformations that could be apparent at birth or manifested in later stages of life. Morbidity is high in anencephaly, whereas in spina bifida, there are neurological and motor disorders. These defects deserve paramount importance in clinical dentistry. Latex allergy, dental caries, difficulty in mouth opening, and sitting in a dental chair are common problems. There is a high risk of anaphylactic response during anaesthesia. There could be associated craniosynostosis causing maxillary deficiency, and malformed sella turcica might be seen. An association of the defects has been linked with orofacial clefts and Down syndrome. PMID:23255477

PubMed

Tigecycline is a new glycylcyclin with a wide spectre including multi-resistant bacteria. Our laboratory tests in routine the in vitro activity of the TGC towards clinically significant isolates of 3rd generation cephalosporins resistant enterobacteriaceae (EC3R), Acinetobacter baumannii and Bacteroides fragilis group (BFG). The objective of this study is to describe the in vitro activity of TGC against these strains isolated between 2008 and 2011 in the university hospital of Montpellier. In this study period, 1070 isolates EC3R including 541 extended spectrum ?-lactamase-producers (ESBL) strains, 47 isolates of A. baumannii including 40 multi-resistant isolates and 645 isolates of BFG were tested. Minimum inhibitory concentrations (MIC) were determined using the E-test method. TGC was active against 86.2% of EC3R with a MIC 90 less or equal to 1mg/L (Escherichia coli being the most sensitive species). A. baumannii and BFG were also inhibited at low concentrations of TGC with a MIC 90 less or equal to 2mg/L respectively for 47% and 84.2% of the isolates. Our study confirms the activity of TGC against the EC3R including ESBL-producers strains. The relevance of the therapeutic use of TGC on the BFG isolates with a MIC greater than 2mg/L should be better documented. Often prescribed in therapeutic impasse, the proper use of TGC would require: clarifying the threshold of sensitivity for some species (i.e., A. baumannii, Bacteroides fragilis group); a better understanding of correlation between in vitro and in vivo activity.

Estrogenicity of resin-based composites and sealants used in dentistry.  

PubMed Central

We tested some resin-based composites used in dentistry for their estrogenic activity. A sealant based on bisphenol-A diglycidylether methacrylate (bis-GMA) increased cell yields, progesterone receptor expression, and pS2 secretion in human estrogen-target, serum-sensitive MCF7 breast cancer cells. Estrogenicity was due to bisphenol-A and bisphenol-A dimethacrylate, monomers found in the base paste of the dental sealant and identified by mass spectrometry. Samples of saliva from 18 subjects treated with 50 mg of a bis-GMA-based sealant applied on their molars were collected 1 hr before and after treatment. Bisphenol-A (range 90-931 micrograms) was identified only in saliva collected during a 1-hr period after treatment. The use of bis-GMA-based resins in dentistry, and particularly the use of sealants in children, appears to contribute to human exposure to xenoestrogens. Images Figure 1. A Figure 1. B Figure 2.

Utilizing learning theory to promote effectiveness of instruction in preclinical operative dentistry.  

PubMed

In comparing two methods of instruction, one must be cautious about forming conclusions because of certain variables which can influence results. Such variables are differences in populations, in instructor effectiveness, and in availability of instructional aids. The comparison does, however, demonstrate differences between the two groups. The fact that the entire class taught by the modified course passed the proficiency examination after nine trials, compared to 12 for those from the traditional course, is not in itself significant. The impressive fact is that in the early trials the rate of students who qualified for clinical practice was nearly doubled in the learning theory group. This might imply that the learning theory group demonstrated a greater degree of problem-solving ability because of opportunities for discovery learning within the course. Since both classes were given the proficiency examination approximately two-and-a-half months after they had completed the preclinical course, it would seem that the learning theory design resulted in retention of the objectives of the course by a significant number of students. Consequently, it is the authors' opinion that the learning theory design provided a more effective method of instruction. Clinical operative dentistry consists of highly intricate procedures which for their successful completion require complex psychomotor responses in the operator. Therefore a program of instruction in operative dentistry must be highly effective. When such a program is organized, utilization of learning theory principles, especially those of skill learning, may aid in achieving this goal. PMID:1062444

Choosing Public Health Dentistry as a Career: A Cross-Sectional Study  

PubMed Central

Objectives: The purpose of this study was to assess the attitude of dental students towards considering Public Health Dentistry as their future career. Materials and Methods: A questionnaire based, cross-sectional survey was conducted, which included dental students from different years of study. It consisted of 27 questions that were graded on five point Likert scale. Results: A total of 293 of the 320 registered undergraduate students participated in the study, with an overall response rate of 91.5%. Among the sample, 80 (27%) were males and 213 (73%) were females. Among the total sample which was studied, it was observed that only one third (35.4%) of them had high attitude towards selecting Public Health Dentistry as a future career, and nearly two thirds of them (58.02%) had an average attitude, with very few students having low attitude (6.48%). Conclusion: The present study concluded that there was an average attitude of 58% among dental students, which showed that they had a considerable amount of interest in pursuing post graduation in this speciality. Efforts should be intensified, both by dental council and by the dental colleges, to develop this speciality, keeping in mind the increasing attitude of dental undergraduates towards it. This also helps in increasing the number of dental personnel who are specialized in implementation of oral health policy, which does not exist in India.

Prospective utility of therapeutic ultrasound in dentistry--Review with recent comprehensive update  

PubMed Central

Background: The utility of ultrasound (US) for therapeutic purposes is still in its infancy. Therapeutic US (TUS) has been used widely in medical field for urological application, surgical intervention, bone healing, and osteointegration in cancer and healing of full thickness excised skin lesions, and within dentistry as a prediagnostic, diagnostic and therapeutic purpose. The purpose of the paper is to review and determine the efficacy of US as one of the treatment modalities for its role in maxillofacial region to reduce pain and promote soft tissue healing. Materials and Methods: A Medline search included of the international literature published between 1976 and 2011 and was restricted to English language articles, published work of past researchers including in vitro and in vivo studies, recent additions of textbooks on surgical and therapeutic applications of US and, current articles in conference papers and reports accessed from the internet using Google search engine on therapeutic ultrasound. Results: Very few article regarding effect of therapeutic of US for its use of insonation for treatment of patient with pain and soft tissue injury are available. This review article mainly emphasizes the therapeutic utility of US in dentistry for its effectiveness to decrease joint stiffness, reduce pain and muscle spasms and improve muscle mobility. In vivo studies have shown very little clinical effects. Conclusions: Further research is warranted in this clinically important area to make the development of noninvasive, multifunctional ultrasound devices for repair, regeneration and other therapeutic utility a success.

A novel shape representation of the dental arch and its applications in some dentistry problems.  

PubMed

Standardized digital images of maxillary dental casts of 47 subjects were analyzed using MATLAB software whereby the two hamular notches and the incisive papilla defines the Cartesian vertical and horizontal axes, as well as the origin. The angle and length of the midpoints of the anterior teeth, mesiobuccal and distobuccal cusp of the posterior teeth were measured from the origin and denoted as ?(1), …, ?(18) and l(1), …, l(18) respectively. These values were collectively used to represent the shape of each dental cast. Clustering and principal component analyses were employed to find possible groups of dental arches using the above measure of shape. The main result of this study is that the 3 groups of dental arch shape may be represented by the novel feature vector v(k) = (?(k)(1), l(k)(1), ?(k)(3), l(k)(3), ?(k)(5), l(k)(5), ?(k)(13), l(k)(13)), k = 1, 2, 3. Knowledge of v(k) implies three impression trays should be sufficient in a particular prosthetic dentistry application for Malaysian patients. Further, given that v(k) are accurately measured they may be potential candidates as evidence in specific application of forensic dentistry. PMID:22255484

Community paramedics fill gaps, take load off EDs.  

PubMed

In a continuing effort to ease demand on busy EDs, some communities are coming up with new ways to leverage paramedics. Under a three-year pilot program in Raleigh, NC, a select group of paramedics with added training are being used to assess patients with mental health or addiction problems and transfer them to alternative facilities when appropriate. In Robbinsdale, MN, a community paramedicine program is filling in care gaps for patients with chronic diseases and other complaints who are at risk for repeat ED visits or inpatient hospitalizations. * Administrators of the Raleigh, NC, program say that in 2013, paramedics diverted more than 300 patients to alternative facilities. Of these, only 20% to 25% need further transport to the hospital. * Every time the NC paramedics divert a patient from the ED to an alternative facility, they return an estimated 14 bed-hours back to the ED. * In addition to responding to patients with non-urgent needs, the Robbinsdale, MN, community paramedicine program is a referral source for ED physicians who are concerned about follow-up care for patients who have presented to the ED with medical problems that require ongoing attention.

[How does success in the 1st cycle of medical school relate to outcome in the 3rd doctorate? Behavior of 1st generation students at the Brussels Free University under the numerus clausus].  

PubMed

The aim of our work was to use the results of the 1st cycle of study in medical school to explore success in 3rd doctorate students in two cohorts (n = 82) of 1st generation students in the numerus clausus system. Because of the homogeneity of mean percentages in the two cohorts and the nil cohort effect on the evolution of performance across study years, the two samples were combined for further analyses. While success (end-of-year percentage) in each of the 3 years of the 1st cycle was positively correlated to success in the other two, the positions (according to ranks) of the students in their group only weakly coincided, if at all, between the 1st cycle and the 3d doctorate. The analysis of correlations between percentages in the 4 years (3 years in the 1st cycle and 3d doctorate) showed that 25% of the variance in the 3d doctorate is shared with outcome in the 1st year and only 7% with that in the 2d year; outcome in the 3d year of the 1st cycle did not contribute at all to outcome in the 3d doctorate. Besides, the chance of an excellent success in the 3d doctorate, defined as being among the 10 best performers, was positively associated to the end-of-year percentage in the 1st year, while neither 2d year nor 3d year results contributed to the prediction, as the logistic regression analysis demonstrated. These results, with a significant contribution of the 1st study year outcome to the success in the 3d doctorate of medical school, were obtained in the context of the numerus clausus and contrast with those obtained in a study preceding this selective procedure, and showing instead the 3d year of the 1st cycle as more predictive. This result could be taken as supporting the very newly established selection process at the end of the 1st study year. PMID:16608007

miR-345 in Metastatic Colorectal Cancer: A Non-Invasive Biomarker for Clinical Outcome in Non-KRAS Mutant Patients Treated with 3rd Line Cetuximab and Irinotecan  

PubMed Central

Introduction MicroRNAs (miRNAs) have important regulatory functions in cellular processes and have shown promising potential as prognostic markers for disease outcome in patients with cancer. The aim of the present study was to find miRNA expression profiles in whole blood that were prognostic for overall survival (OS) in patients with metastatic colorectal cancer (mCRC) treated with cetuximab and irinotecan. Methods From 138 patients with mCRC in 3rd line therapy with cetuximab and irinotecan in a prospective phase II study, 738 pretreatment miRNAs were isolated and profiled from whole blood using the TaqMan MicroRNA Array v2.0. Mutation status of KRAS, BRAF, and PI3KCA was known. Results After Bonferroni adjustment, 6 miRNAs: (miR-345, miR-143, miR-34a*, miR-628-5p, miR-886-3p and miR-324-3p), were found associated with short OS. miR-345 was the strongest prognostic miRNA, significant in the full cohort and in the non-KRAS mutant population. miR-345, as a continuous variable in the full cohort, resulted in a hazard ratio (HR) of 2.38 per IQR (CI 95%: 1.8–3.1, P-value?=?2.86e?07, Bonferroni adjusted, univariable analysis) and a HR?=?1.75 per IQR (CI 95%: 1.24–2.48, P-Wald?=?1.45e-03) in the multivariable analysis adjusted for gender, age, KRAS, PI3KCA and performance status. miR-345 was prognostic in progression-free survival (PFS) with a HR?=?1.63 per IQR (CI 95%: 1.25–2.114, P-Wald?=?2.92e-4) in the multivariable analysis. In addition, high miR-345 expression was associated with lack of response to treatment with cetuximab and irinotecan. Conclusion We identified miR-345 in whole blood as a potential biomarker for clinical outcome. MiR-345 was a single prognostic biomarker for both OS and PFS in all patients and also in the non-KRAS mutant population.

Increasing general dentists' provision of care to child patients through changes in the undergraduate pediatric dentistry program.  

PubMed

Reduced caries rates and an increased percentage of children with dental insurance have made it more difficult for dental schools to provide undergraduates with sufficient numbers of pediatric dental patients requiring restorative procedures. This may result in graduates who are not competent and are reluctant to treat children after graduation. To ensure the quality of the undergraduate clinical training program, the Division of Pediatric Dentistry at the University of Manitoba changed from a comprehensive-based clinic to a block system in 1998-99. Specific communities with limited access to dental care (neighboring core area schools and Hutterite colonies) were specifically targeted as potential sources for child patients. This format increased the exposure of students to patient management as well as to complex pediatric dentistry procedures. To assess the learning experiences before and after the changes to the clinical pediatric dentistry program, sixty general dentists who had graduated from the University of Manitoba were randomly selected using the Manitoba Dental Association Directory. Surveys were sent to twenty general dentists who graduated in each of the following years: 1993, 2000, and 2002. Forty-five dentists responded, fifteen from each of the three surveyed classes. Dentists who graduated after the changes to the program (2000, 2002) reported that they performed a greater number of complex pediatric dentistry procedures and treated more toddler and preschool children than the group that graduated before the changes (1993). Referrals to pediatric dentistry specialists were higher in the 1993 group than in the 2000 and 2002 groups. In conclusion, an adequate pool of pediatric patients is critical to provide dental students with sufficient learning experiences. The dentists who graduated from the program after the changes were implemented are providing more comprehensive treatment to younger children. PMID:15749948

Full mouth rehabilitation of severe fluorozed teeth with an interdisciplinary approach (6 handed dentistry).  

PubMed

Whenever the treatment revolves around structural balance and aesthetic harmony, the crux remains to be the periodontal health of the existing dentition. In such scenarios where restorations and aesthetics are of concern, biologic width (BW) is the initial and final frontier. Considering attrition of teeth, the resistance which is offered by them is definitely at a lower level as compared to teeth with adequate height. Clinical crowns of worn out teeth are seriously handicapped when it comes to bearing the occlusal loads, which can be brought back to normalcy by crown lengthening . Crown lengthening includes the surgical removal of soft and hard periodontal architecture to gain (vertical dimension) a supracrestal tooth length, thus allowing a longer clinical crown reestablishment of BW. This paper has described the full mouth rehabilitation of severe fluorozed and attrited teeth in a 35-year male with the use of an interdisciplinary approach (6 Handed Dentistry). PMID:24298538

The High Frequency Ultrasonic Diagnostic System for Hard and Soft Tissue Specific Assessments in Dentistry  

NASA Astrophysics Data System (ADS)

The numerical assessment of dental tissues is essential when selecting a relevant treatment protocol in the field of dentistry. This will have significant ramifications on the restoration quality of dental tissues. The aim of the research study presented in this thesis was to validate applicability and obtain non-invasively, quantitative data for hard and soft tissue thickness in dental applications. An ultrasonic system was developed and assembled for the purpose of these experiments. Numerous laboratory trials were conducted to validate system performance against traditional and destructive methods of assessment. Ultrasonic measurements were found to yield similar values to those obtained from invasive methods. Results obtained in these experiments have validated potentials of ultrasound as a supplementary diagnostic tool for dental healthcare.

Ball lens based lensed patch cord probes for optical coherence tomography in the field of dentistry  

NASA Astrophysics Data System (ADS)

A lensed patch cord probe has been made with a ball lens packaged in a metal cylinder. By simply placing a ball lens directly in front of a fiber patch cord, a compact and potentially disposable sampling probe for optical coherence tomography (OCT) could be implemented. To achieve a sufficiently long working distance and a good transverse resolution simultaneously, the proper ball lens diameter and the distance between the ball lens and the fiber patch cord were investigated. Experimentally, a working distance of up to 5.2 mm, 3 dB bandwidth of 2 mm, and transverse resolution of 16 ?m were achieved. With the patch cord probe, a common path swept source OCT system was implemented and used to demonstrate the feasibility as the dedicated probe for dentistry.

Evidence-based dentistry and clinical implementation by third-year dental students.  

PubMed

Over the last two decades, the concept of evidence-based medicine (EBM) has become the standard of medical care. Defined by Sackett et al. as "the conscientious, explicit, and judicious use of current best evidence in making decisions about the care of individual patients," EBM recognizes that the practitioner should combine individual clinical expertise with the best available external evidence for optimal care. Consideration of the patient's needs and preferences is also an integral component of the clinical application. Dental educators have to account for the fact that not all dental treatment outcomes have been researched with randomized clinical trials. Dogmas in dentistry still exist regarding restorative treatments and methods taught to next generations of practitioners, while limited evidence is available. The purpose of this study was to determine how third-year dental students at one U.S. dental school select articles to provide supportive evidence related to treatment planning. The results show that knowledge provided in a three-week course in evidence-based dentistry (EBD) for first-year dental students was not efficiently applied when the students reached their third year. A significant percentage of the students perceived the use of literature as not beneficial for sustaining clinical aspects of a treatment plan, and they did not use appropriate tools to access best available resources. As a result of these findings, the article proposes incorporation of specific learning objectives related to EBD principles throughout the curriculum and a simplified method to search for best available evidence that has the advantage of not requiring knowledge and training in rigorous formulation of clinical questions.

[Community aspects of geriatric dentistry--a literature review: 1975-2000].  

PubMed

The world's population is in transition, but there is an inevitable move in all societies towards an aging population. There is an agreement that the ability of the geriatric population to adjust to the "third age" depends on the will of the society and the community to provide services and to support this vulnerable and dependent population. The preponderance of oral health issues and their impact upon general health and quality of life have prompted a variety of geriatric related efforts over the last 20 years. Predoctoral and postdoctoral education and training efforts have been initiated, geriatric research agendas have started to yield important findings, and a few service programs have marginally helped improve dental care access for the geriatric population. Past discoveries have enabled large portions of the world's population to enjoy far better oral health than their forebears a century ago. Although different patterns of dental needs emerge throughout the world, the "silent epidemic" of oral diseases is affecting the most vulnerable parts of the population: the poor children, the elderly and many members of racial and ethnic minority groups. The review of the literature of community aspects of geriatric dentistry in the past twenty-five years will be introduced in two articles. The first article summarizes the important issues of demography, oral health condition, changes in attitude towards oral health of the geriatric population, oral health services given in geriatric institutions and mobile dentistry. The issues of law and ethics, development of public and community oral health programs for the geriatric population and plans as well as trends for the future will be discussed in the second article. Setting goals and presenting data are steps in the right direction but are not enough; the success will be measured by the ability to make things happen. The continuing anticipated growth of the geriatric population will, hopefully, be translated into a rising political power and to fruitful and practical health outcomes. PMID:16323405

Ambienti Circumstellari ed Interstellari di Supernovae di vario Tipo ed Applicazioni Astrofisiche  

NASA Astrophysics Data System (ADS)

Nella presente tesi vengono studiati gli ambienti circumstellari ed interstellari di supernovae (anche SNe; singolare SN) di vario tipo. In particolare si descrivono alcune applicazioni astrofisiche, relative a questi ambienti, che permettono di desumere informazioni sui sistemi stellari progenitori delle supernovae o di determinare le distanze a tali oggetti. L' emissione radio da supernovae, prodotta nell' ambiente circumstellare ad opera dell'interazione idrodinamica del gas di SN con l' ambiente circostante, puo' essere impiegata come mezzo di indagine del sistema di pre-supernova. In particolare si e' introdotta l'idea che tale emissione possa essere impiegata nel caso delle SNe di tipo Ia come test dei sistemi progenitori di tipo simbiotico. Il test e' stato effettuato sulla SN 1986G, per la quale avevamo ottenuto limiti superiori a lunghezze d'onda radio. Nel caso che un sistema simbiotico sia responsabile di una SN Ia, l'interazione tra l' ejecta e una shell circumstellare origina, in un'epoca molto prossima al massimo di luce, un'emissione radio rivelabile con strumenti tipo Very Large Array. Inoltre l'emissione radio fornisce informazioni circa gli stadi di pre-supernova nel caso di altri tipi di supernova. In questo lavoro di tesi vengono presentati i risultati ottenuti nel caso delle SNe di tipo II 1984E e 1986E. Queste due SNe non mostrano emissione radio: la prima, in prossimita del massimo ottico, stava interagendo con una shell circumstellare prodotta da un episodio di perdita di massa di breve durata in fase di pre-supernova; la seconda, invece e' la prima SN ``vecchia'' ad essere rivelata nell' ottico ma non nel radio (l' oggetto non ha ancora iniziato la fase di supernova remnant ed emette radiazione ottica prodotta ancora per interazione circumstellare). In ambiente circum-interstellare, gli echi di luce, prodotti dallo scattering della luce della supernova ad opera della polvere presente, possono essere utilizzati per determinare le distanze extra-galattiche per via puramente geometrica (Sparks 1994; 1996). Osservazioni da terra, in imaging e polarimetria, sono state utilizzate per selezionare un numero promettente di candidati, che mostrano emissione visibile alla posizione della supernova. Tali candidati sono promettenti non solo per l' applicazione del metodo descritto ma anche per dedurre informazioni circa le supernovae medesime e le relative popolazioni stellari.

The NASA Star and Exoplanet Database (NStED)  

NASA Astrophysics Data System (ADS)

The NASA Star and Exoplanet Database (NStED) is an archive and search facility for data on a variety of published measurements of positions, kinematics, photometry, multiplicity, activity, other fundamental stellar properties, and datum of interest to the stellar astronomy, and the planet finding community in particular. The initial population of stars is currently the Hipparcos catalog but will soon expand to include the entire Tycho-2 catalog supplemented with Kepler and CoRoT catalogs. This base is merged with data taken from other published catalogs (e.g. 2MASS, etc.), tabular data from published papers, as well as images, spectra and transit light curve data. NStED allows users to fully trace the data to the original publication and provides an option to view the 'as published' value of the datum. There are currently 140,230 stars in NStED.

Haz-Ed: Classroom Activities for Understanding Hazardous Waste  

NSDL National Science Digital Library

Haz-Ed is a compilation of interdisciplinary activities that focus on the scientific, technical, and political issues related to hazardous waste sites and Superfund (the U.S. Environmental Protection Agency program to locate, investigate, and clean up hazardous waste sites nationwide). Haz-Ed materials can be used as part of a larger curriculum, as special stand-alone activities, or on an occasional basis to teach students about hazardous waste issues. The materials are designed to help students develop skills in critical thinking, problem solving, and decision making. They also increase environmental awareness and encourage an environmental ethic in students. The Introduction defines the components of the materials which will enable teachers to design their own organization for the Haz-Ed activities. All materials listed are linked to a PDF format in addition to the web enabled format.

Reduction of Electron Channeling in EDS using Precession  

PubMed Central

We demonstrate that EDS measurement can be significantly improved by precessing the electron beam, thereby reducing electron channeling effects. For a SrTiO3 specimen orientated along [001] zone axis, the measured strontium to titanium atomic ratio was 0.74 – 0.80 using conventional EDS methods, and the ratio was improved to ~0.99 by precessing the electron beam for angles greater than 22.54 mRad. In ALCHEMI-like experiments in which the specimen was tilted to near two-beam condition, the strontium to titanium ratio was insensitive to the deviation from the Bragg condition using a precessed electron beam. Similar reduction of electron channeling effects was also observed in precession-assisted EDS measurements for an L21-ordered Fe2MnAl intermetallic alloy tilted to [011] zone axis as well as near two-beam conditions.

Automated SEM-EDS GSR Analysis for Turkish Ammunitions  

SciTech Connect

In this work, Automated Scanning Electron Microscopy with Energy Dispersive X-ray Spectrometry (SEM-EDS) was used to characterize 7.65 and 9mm cartridges Turkish ammunition. All samples were analyzed in a SEM Jeol JSM-5600LV equipped BSE detector and a Link ISIS 300 (EDS). A working distance of 20mm, an accelerating voltage of 20 keV and gunshot residue software was used in all analysis. Automated search resulted in a high number of particles analyzed containing gunshot residues (GSR) unique elements (PbBaSb). The obtained data about the definition of characteristic GSR particles was concordant with other studies on this topic.

Multivariate statistical analysis of low-voltage EDS spectrum images  

SciTech Connect

Whereas energy-dispersive X-ray spectrometry (EDS) has been used for compositional analysis in the scanning electron microscope for 30 years, the benefits of using low operating voltages for such analyses have been explored only during the last few years. This paper couples low-voltage EDS with two other emerging areas of characterization: spectrum imaging and multivariate statistical analysis. The specimen analyzed for this study was a finished Intel Pentium processor, with the polyimide protective coating stripped off to expose the final active layers.

Characterization of pyrotechnic reaction residue particles by SEM/EDS.  

PubMed

Today the method commonly used for detecting gunshot residue is through the combined use of scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). In recent years, this same methodology began to find use in detecting and characterizing pyrotechnic reaction residue (PRR) particles whether produced by explosion or burning. This is accomplished by collecting particulate samples from a surface in the immediate area of the pyrotechnic reaction. Suspect PRR particles are identified by their morphology (typically 1 to 20 microm spheroidal particles) using an SEM; then they are analyzed for the elements they contain using X-ray EDS. This can help to identify the general type of pyrotechnic composition involved. PMID:12762523

[Repercussions at the level of required health insurance of the introduction of three distinct professional titles in dentistry].  

PubMed

From July 2007 on, Belgian dental graduates must complete one year of vocational training in general dentistry or a specialization in the field of either orthodontics or parodontology in order to obtain a licence for the Belgian Social Security System. This introduction of special professional titles required massive legislation in concert with State Health Insurance (RIZIV/INAMI), the Departments of Education of both Communities, manpower planning, comparable arrangements for physicians, and European Directives. Overall the process of subsequent changes in legislation and implementation took up to 15 years. The author includes some critical remarks and indicates what still needed to be done at the end of 2005 to conclude this far-reaching change in the organisation of dentistry in Belgium.

The Burned Patient: Assessment, Diagnosis, and Management in the ED  

Microsoft Academic Search

Burn injuries frequently present to the emergency department (ED). In the majority of cases, the burns are minor, yet, they require a careful assessment, cleaning, dressing, and careful fol- low-up. In the pediatric and geriatric populations, careful atten- tion, to the history and physical examination, and an awareness of burn patterns associated with abuse, may protect the patient from further
