title: Chavs, Neds, Neets and Yobs: The Anti-Social Underclass of the United Kingdom
Creators: name: Marra, Alexander Michael
Publisher: name: Old Dominion University Libraries
Year: 2008

description: This work is the result of the first look by an American into anti-social and yobbish behavior in the UK, and who's responsible for it. The delinquent subculture whose members are alternately either known as chavs or neds will be analyzed in detail. In addition, the NEET, the British government's designation for those who are not in employment, education, or training, will also be analyzed for the roots and reasons behind what may come to be known as the NEET generation in the UK in the years to come. For now they are sometimes called the ASBO generation because of the proliferation of Anti-Social Behavior Orders since the England and Wales Crime and Disorder Act of 1998.

Indirectly and implicitly, British youth culture, the UK criminal justice system and British socio-economic issues in general will be compared to their equivalents in the US. This thesis is the first of its kind to be not only conducted by an American, but the first of its kind to be directed towards an American audience. For years now antisocial behavior has been quietly wreaking havoc on the UK while Americans are still holding to the myth that we hold the monopoly on violence, disorder and crime in the industrialized First World. This work's purpose is to educate Americans on a unique British delinquent subculture but also to provide the Brits with a fresh American response to what is becoming all too commonplace in the British Isles. The Brits lead the world in legislation and mobilization against anti-social behavior but progress in reducing it still eludes them. This paper is an American's concern for a country he holds dear, in hopes of eventually finding a cure for its worst ailment.

description: Let ${\rm SL(2, \mathbb H)}$ be the group of $2 \times 2$ quaternionic matrices with Dieudonné determinant $1$. The group ${\rm SL(2, \mathbb H)}$ acts on the five dimensional hyperbolic space by isometries. We investigate extremality of Jørgensen type inequalities in ${\rm SL(2, \mathbb H)}$. Along the way, we derive Jørgensen type inequalities for quaternionic Möbius transformations which extend earlier inequalities obtained by Waterman and Kellerhals.

description: The Majorana Demonstrator is an ultra-low background physics experiment searching for the neutrinoless double beta decay of $^{76}$Ge. The Majorana Parts Tracking Database is used to record the history of components used in the construction of the Demonstrator. The tracking implementation takes a novel approach based on the schema-free database technology CouchDB. Transportation, storage, and processes undergone by parts such as machining or cleaning are linked to part records. Tracking parts provides a great logistics benefit and an important quality assurance reference during construction. In addition, the location history of parts provides an estimate of their exposure to cosmic radiation. A web application for data entry and a radiation exposure calculator have been developed as tools for achieving the extreme radio-purity required for this rare decay search.

description: Recent theoretical and experimental efforts have shown the remarkable and counter-intuitive role of noise in enhancing the transport efficiency of complex systems. Here, we realize simple, scalable, and controllable optical fiber cavity networks that allow us to analyze the performance of transport networks for different conditions of interference, dephasing and disorder. In particular, we experimentally demonstrate that the transport efficiency reaches a maximum when varying the external dephasing noise, i.e. a bell-like shape behavior that had been predicted only theoretically. These optical platforms are very promising simulators of quantum transport phenomena, and could be used, in particular, to design and test optimal topologies of artificial light-harvesting structures for future solar energy technologies.

Internal and external resorption in a lower molar with an associated endodontic-periodontic lesion: A case report
Creators: name: Komabayashi, T.
name: Zhu, Q.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2012

description: This article describes a unique case in which both internal and external inflammatory resorption and endodontic-periodontic lesions were present at the same time in the patient's left mandibular first molar. Based on clinical and radiographic findings, it was determined that the nature of this case was a pulpal infection-induced inflammatory resorption and furcation lesion. After root canal therapy, the furcation lesion and external inflammatory resorption were completely resolved. This case indicates that the correct diagnosis of the stimulating factor for tooth resorption and determination of the primary origin of endodontic-periodontic lesions are critical for clinical management and success.

description: The Upsilon Andromedae system is the first exoplanetary system to have the relative inclination of two planets' orbital planes directly measured, and therefore offers our first window into the 3-dimensional configurations of planetary systems. We present, for the first time, full 3-dimensional, dynamically stable configurations for the 3 planets of the system consistent with all observational constraints. While the outer 2 planets, c and d, are inclined by about 30 degrees, the inner planet's orbital plane has not been detected. We use N-body simulations to search for stable 3-planet configurations that are consistent with the combined radial velocity and astrometric solution. We find that only 10 trials out of 1000 are robustly stable on 100 Myr timescales, or about 8 billion orbits of planet b. Planet b's orbit must lie near the invariable plane of planets c and d, but can be either prograde or retrograde. These solutions predict b's mass is in the range 2 - 9 $M_{Jup}$ and has an inclination angle from the sky plane of less than 25 degrees. Combined with brightness variations in the combined star/planet light curve ("phase curve"), our results imply that planet b's radius is about 1.8 $R_{Jup}$, relatively large for a planet of its age. However, the eccentricity of b in several of our stable solutions reaches values greater than 0.1, generating upwards of $10^{19}$ watts in the interior of the planet via tidal dissipation, possibly inflating the radius to an amount consistent with phase curve observations.

description: Introduction: Mineral trioxide aggregate (MTA) has been used successfully for perforation repair, vital pulpotomies, and direct pulp capping. However, little is known about the interactions between MTA and glass ionomer cement (GIC) in final restorations. In this study, 2 null hypotheses were tested: (1) GIC placement time does not affect the MTA-GIC structural interface and hardness and (2) moisture does not affect the MTA-GIC structural interface and hardness. Methods: Fifty cylinders were half filled with MTA and divided into 5 groups. The other half was filled with resin-modified GIC either immediately after MTA placement or after 1 or 7 days of temporization in the presence or absence of a wet cotton pellet. The specimens were then sectioned, carbon coated, and examined using a scanning electron microscope and an electron probe microanalyzer (SEM-EPMA) for interfacial adaptation, gap formation, and elemental analysis. The Vickers hardness numbers of the interfacial MTA were recorded 24 hours after GIC placement and 8 days after MTA placement and analyzed using the analysis of variance test. Results: Hardness testing 24 hours after GIC placement revealed a significant increase in hardness with an increase of temporization time but not with a change of moisture conditions (P <.05). Hardness testing 8 days after MTA placement indicated no significant differences among groups. SEM-EPMA showed interfacial adaptation to improve with temporization time and moisture. Observed changes were limited to the outermost layer of MTA. The 2 null hypotheses were not rejected. Conclusions: GIC can be applied over freshly mixed MTA with minimal effects on the MTA, which seemed to decrease with time.

description: Introduction: Capasio is being developed as a new generation of endodontic material with potential use as a root-end filling material. The aim of this study was to compare the ability of Capasio and mineral trioxide aggregate (MTA) to penetrate human dentinal tubules and examine the interaction of Capasio and MTA with a synthetic tissue fluid (STF) and root canal walls in extracted human teeth. Methods: Root-end preparations were filled with Capasio or MTA, allowed to set for 4 weeks in STF, and then sectioned at 1, 2, and 3 mm from resected surface. Depth of penetration was evaluated by using scanning electron microscopy (SEM). Next, Capasio and MTA samples were prepared both in 1-g pellets and in root-end preparations. Samples were placed in STF, allowed to set, and then characterized by using SEM, energy dispersive x-ray analysis (EDXA), and x-ray diffraction (XRD) techniques. Results: Penetration of Capasio into dentinal tubules was observed at all levels. No penetration of MTA into dentinal tubules was observed at any level. Both Capasio and MTA formed apatite crystals in the supernatant, on their exposed surfaces, and in the interfacial layers that were similar in structure and elemental composition when evaluated by using SEM and EDXA. XRD analysis of these crystals corresponds with those reported for hydroxyapatite. Conclusions: When used as a root-end filling material, Capasio is more likely to penetrate dentinal tubules. Both Capasio and MTA promote apatite deposition when exposed to STF.

description: Under the main assumption that the axion scalar field mainly composes the dark matter in the Universe, in this paper we shall extend the formalism of kinetic axion $R^2$ gravity to include Gauss-Bonnet terms non-minimally coupled to the axion field. As we demonstrate, this non-trivial Gauss-Bonnet term has dramatic effects on the inflationary phenomenology and on the kinetic axion scenario. Specifically, in the context of our formalism, the kinetic axion ceases to be kinetically dominated at the end of the inflationary era, since the condition $\dotϕ\simeq 0$ naturally emerges in the theory. Thus, unlike the case of kinetic axion $R^2$ gravity, the Gauss-Bonnet corrected kinetic axion $R^2$ gravity leads to an inflationary era which is not further extended and the reheating era commences right after the inflationary era, driven by the $R^2$ fluctuations.

description: Geriatric dentistry and its instruction are critical in a rapidly ageing population. Japan is the world's fastest-ageing society, and thus, geriatric dentistry education in Japan can serve as a global model for other countries that will soon encounter the issues that Japan has already confronted. This study aimed at evaluating geriatric dental education with respect to the overall dental education system, undergraduate geriatric dentistry curricula, mandatory internships, and graduate geriatric education of a selected dental school in Japan. Bibliographical data and local information were collected. Descriptive and statistical analyses (Fisher and chi-squared test) were conducted. Japanese dental schools teach geriatric dentistry in 10 geriatric dentistry departments as well as in prosthodontic departments. There were no significant differences found between the number of public and private dental schools with geriatric dentistry departments (P=0.615). At Showa University School of Dentistry, there are more didactic hours than practical training hours; however, there is no significant didactic/practical hour distribution difference between the overall dental curriculum and fourth-year dental students' geriatric dental education curriculum (P=0.077). Graduate geriatric education is unique because it is a 4-year PhD course of study; there is neither a master's degree programme nor a certificate programme in geriatric dentistry. Overall, both undergraduate and graduate geriatric dentistry curricula are multidisciplinary. This study contributes to a better understanding of geriatric dental education in Japan; the implications of this study include developing a clinical/didactic curriculum, designing new national/international dental public health policies, and calibrating the competency of dentists in geriatric dentistry.

description: Active ingredients containing fluorinated organic compounds such as Fluoroalkylamines or pyrimidine-based molecules are promising in the field of agriculture (pesticides and herbicides) and pharmacology (antibiotics). The massive use of these molecules will result in a massive increase in waste containing this type of molecule. Developed countries have restrictive waste management policies, which is not the case in developing countries. In the latter, we are witnessing a proliferation of storage areas and open-air disposal of waste, sometimes from developed countries. These practices have enormous consequences on the environment such as air, soil and water pollution and therefore on human health. One of the solutions already proven on solid waste would be the use of plasma torches. These torches can reach high temperatures (5,000 K to 20,000 K). However, the use of these means of treatment is not without danger since toxic or lethal molecules could be produced. In order to understand these difficulties, we propose to study the influence of air on the chemical composition of a plasma based on fluoroalkylamines (trifluoroethylamine: C2H4F3N, nonafluoropentylamine: C5H4F9N, etc.), at atmospheric pressure and at atmospheric pressure. local thermodynamic equilibrium (E.T.L), in a temperature range from 500 K to 20,000 K. In order to obtain the chemical composition of the plasma, we use the Gibbs free energy minimization method. The results obtained show that dangerous and toxic gaseous chemical species such as CF2, CO, HCN and HF appear at low temperatures with high concentration.

description: Objective: A sequential topical application of calcium and fluoride-phosphate solutions was reported to occlude open dentin tubules, mainly with fluoroapatite precipitates by a rapid ionic reaction, and to be effective at treating dentin hypersensitivity. However, its ability to reduce dentin permeability (Lp) is unknown. The aim of this in vitro study was to evaluate the effect of this treatment on Lp. Methods: Nine extracted human third molars were sectioned transversely to obtain 0.5 mm-thick discs, which were then etched and rinsed. Aqueous solutions of 5% (w/w) disodium phosphate containing 0.3% (w/w) sodium fluoride (A) and 10% (w/w) calcium chloride (B) were prepared. The sequential application of the A&B solutions was repeated three times on each disc, which was then rinsed with distilled water. The Lp of the discs was measured before and after the application using a modified Pashley's fluid flow measuring system. The differences in the Lp values between the conditions before and after the solution applications were analysed using a generalized estimating equation method and paired t-test. Scanning Electron Microscopy (SEM) was used to observe the dentin surfaces. Results: All nine discs consistently indicated reduced Lp following the application of the A&B solutions. There was a significant decrease in the mean Lp [μL/(cm2 s cm H 2O)] from baseline (-0.27 ± 0.25, p = 0.011). Overall, an average decrease of 34% Lp occurred after the application of the A&B solutions. SEM observation indicated that the reaction products covered the entire dentin disc surface. Conclusion: The application of the A&B solutions was effective at reducing the Lp of the dentin discs.

description: In 2018, images were released of a planet being formed around the star PDS 70, offering a tantalizing glimpse into how planets come into being. However, many questions remain about how dust evolves into planets, and astrophysical observations are unable to provide all the answers. It is therefore necessary to perform experiments to reveal key details and, to avoid unwanted effects from the Earth's gravitational pull, it is often necessary to perform such experiments in microgravity platforms. This Review sketches current models of planet formation and describes the experiments needed to test the models.

description: The smart electricity grid enables a two-way flow of power and data between suppliers and consumers in order to facilitate the power flow optimization in terms of economic efficiency, reliability and sustainability. This infrastructure permits the consumers and the micro-energy producers to take a more active role in the electricity market and the dynamic energy management (DEM). The most important challenge in a smart grid (SG) is how to take advantage of the users' participation in order to reduce the cost of power. However, effective DEM depends critically on load and renewable production forecasting. This calls for intelligent methods and solutions for the real-time exploitation of the large volumes of data generated by a vast amount of smart meters. Hence, robust data analytics, high performance computing, efficient data network management, and cloud computing techniques are critical towards the optimized operation of SGs. This research aims to highlight the big data issues and challenges faced by the DEM employed in SG networks. It also provides a brief description of the most commonly used data processing methods in the literature, and proposes a promising direction for future research in the field.

description: Quantum reservoir computing is a neuro-inspired machine learning approach harnessing the rich dynamics of quantum systems to solve temporal tasks. It has gathered attention for its suitability for NISQ devices, for easy and fast trainability, and for potential quantum advantage. Although several types of systems have been proposed as quantum reservoirs, differences arising from particle statistics have not been established yet. In this work, we assess and compare the ability of bosons, fermions, and qubits to store information from past inputs by measuring linear and nonlinear memory capacity. While, in general, the performance of the system improves with the Hilbert space size, we show that also the information spreading capability is a key factor. For the simplest reservoir Hamiltonian choice, and for each boson limited to at most one excitation, fermions provide the best reservoir due to their intrinsic nonlocal properties. On the other hand, a tailored input injection strategy allows the exploitation of the abundance of degrees of freedom of the Hilbert space for bosonic quantum reservoir computing and enhances the computational power compared to both qubits and fermions.

description: Incorporating relativistic physics into quantum tunneling can lead to exotic behavior such as perfect transmission via Klein tunneling. Here, we probe the tunneling properties of spin-momentum locked relativistic fermions by designing and implementing a tunneling geometry that utilizes nanowires of the topological Kondo insulator candidate, SmB6. The nanowires are attached to the end of scanning tunneling microscope tips, and used to image the bicollinear stripe spin-order in the antiferromagnet Fe1.03Te with a Neel temperature of ~50 K. The antiferromagnetic stripes become invisible above 10 K concomitant with the suppression of the topological surface states. We further demonstrate that the direction of spin-polarization is tied to the tunneling direction. Our technique establishes SmB6 nanowires as ideal conduits for spin-polarized currents.

description: Objectives: To quantify in vitro the root dentin moisture (DM) when soaked in 10% ascorbic acid solution (Group A) and distilled water (Group B) for up to 14 days. Methods: Forty-four extracted human mandibular single-rooted teeth were sectioned perpendicular to the long axis at the CEJ to access the root dentin. The samples were divided into Groups A and B. Baseline (day 0) DM was measured using a digital grain moisture meter. One sample was placed in each tube, which was then filled with solution. All tubes were kept at 37 °C and 100% humidity. DM was measured after 1, 3, 7, and 14 days. The baseline DM value was used as a covariate in the generalized estimating equation (GEE) analysis to account for the difference in the baseline DM between the two groups. Results: The mean DM (%) values ± standard deviation on days 0, 1, 3, 7, and 14 were 11.4 ± 1.08, 17.1 ± 0.87, 18.2 ± 0.76, 18.4 ± 0.77, and 17.9 ± 0.90 in Group A, and 10.2 ± 0.95, 12.8 ± 0.90, 13.3 ± 0.95, 13.0 ± 0.91, and 13.2 ± 0.89 in Group B, respectively. Group A had significantly higher baseline DM than Group B (p = 0.006). After adjusting for differences in the baseline, the GEE analysis indicated that, on average, Group A had a significantly higher increase in DM than Group B, with means ± standard deviation of 4.35 ± 0.26. Conclusions: The moisture increase in the ascorbic acid group was greater than that in the distilled water group. Soaking root dentin in the unreplenished ascorbic acid solution or distilled water beyond 3 days did not further increase DM.

description: Based on the Aristotelian concept of potentiality vs. actuality allowing for the study of energy and dynamics in language, we propose a field approach to lexical analysis. Falling back on the distributional hypothesis to statistically model word meaning, we used evolving fields as a metaphor to express time-dependent changes in a vector space model by a combination of random indexing and evolving self-organizing maps (ESOM). To monitor semantic drifts within the observation period, an experiment was carried out on the term space of a collection of 12.8 million Amazon book reviews. For evaluation, the semantic consistency of ESOM term clusters was compared with their respective neighbourhoods in WordNet, and contrasted with distances among term vectors by random indexing. We found that at 0.05 level of significance, the terms in the clusters showed a high level of semantic consistency. Tracking the drift of distributional patterns in the term space across time periods, we found that consistency decreased, but not at a statistically significant level. Our method is highly scalable, with interpretations in philosophy.

title: Gastropod grazing of epiphytic lichens in Western Newfoundland
Creators: name: Flores, Katherine
Publisher: name: Memorial University of Newfoundland
Year: 2021

description: Overgrazing by introduced gastropods has been identified as a potential threat to some rare or threatened epiphytic foliose lichens; however, gastropod grazing severity has not been evaluated within Newfoundland. Lobaria pulmonaria is locally abundant in Newfoundland but considered rare and threatened in parts of the U.S.A and Europe. To evaluate gastropod grazing severity and describe the tree-climbing gastropod community we conducted lichen diversity and lichenivory surveys and used two methods of gastropod sampling. To determine how lichen species diversity affects lichen grazing of L. pulmonaria, we conducted cafeteria feeding experiments using native and introduced snail species and common lichen species from our study area. We found that within the study area, some lichens including L. pulmonaria were severely overgrazed, and that tree-climbing gastropod abundance increased with greater grazing severity. We found that lichenivory severity was driven by tree-level factors and identified the most common tree-climbing slugs within the study area. Feeding experiment results showed that snails consumed greater lichen biomass with greater species diversity; however, distinct preferences for specific lichen species were apparent. Grazing severity of L. pulmonaria decreased with greater lichen species diversity, which suggests that L. pulmonaria may be more resistant to gastropod grazing in forests with higher foliose lichen species diversity.

description: This paper derives Langevin equations for an optical cavity where the dominant nonlinearity arises from free-carrier dispersion. We define a generalized Wigner function, compute a Fokker-Planck equation that approximates the master equation, and convert this to a system of stochastic differential equations. These equations are similar to the Wigner equations for an optical Kerr cavity, but have additional noise terms due to the incoherent carrier excitation and decay processes. We use these equations to simulate a phase-sensitive amplifier and latch and compare the results to a Kerr model.

description: Ecological niche model (ENM) pertains to a class of methodologies that utilise occurrence data alongside environmental data to formulate a correlative model of the environmental circumstances that satisfy a species’ ecological requirements. In the current study, ENM was employed to ascertain the types of habitat for Trichoderma harzianum using machine learning algorithm known as MaxEnt Entropy. Our line of reasoning posits that the efficacy of T. harzianum as a bio-control agent can be enhanced, alongside the advancement of host/crop development and metabolic processes, through its deliberate introduction into geographically appropriate habitats. ENM was performed on 92 spatially thinned presence points of this species across India, considering three bio-climatic time periods (present, 2050, and 2070) and four greenhouse gas scenarios (known as representative concentration pathways RCPs). Non-bioclimatic factors include ecosystem rooting depths (ERD), total plant available water storage capacity (TPAWSC), habitat heterogeneity indices (HHI), land use land cover (LULC) and to soil variables at four depths. Energy-related factors, like Isothermality and minimum temperature of coldest month, were shown to be the most essential for the habitat appropriateness of this species during the current bio-climatic period. Future climate predictions and their associated RCPs revealed that water-related variables, like precipitation of wettest quarter, were the most influential. Non-climatic elements that were shown to have significant impact included soil pH, maximum diversity indices, forest and grassland types, TPAWSC, ERD (95%). Our analysis showed that this species will always find optimal suitability sites in northern eastern India with almost all predictors except root zone variables.

description: Byzantine-robust federated learning aims at mitigating Byzantine failures during the federated training process, where malicious participants may upload arbitrary local updates to the central server to degrade the performance of the global model. In recent years, several robust aggregation schemes have been proposed to defend against malicious updates from Byzantine clients and improve the robustness of federated learning. These solutions were claimed to be Byzantine-robust, under certain assumptions. Other than that, new attack strategies are emerging, striving to circumvent the defense schemes. However, there is a lack of systematic comparison and empirical study thereof. In this paper, we conduct an experimental study of Byzantine-robust aggregation schemes under different attacks using two popular algorithms in federated learning, FedSGD and FedAvg . We first survey existing Byzantine attack strategies and Byzantine-robust aggregation schemes that aim to defend against Byzantine attacks. We also propose a new scheme, ClippedClustering , to enhance the robustness of a clustering-based scheme by automatically clipping the updates. Then we provide an experimental evaluation of eight aggregation schemes in the scenario of five different Byzantine attacks. Our results show that these aggregation schemes sustain relatively high accuracy in some cases but are ineffective in others. In particular, our proposed ClippedClustering successfully defends against most attacks under independent and IID local datasets. However, when the local datasets are Non-IID, the performance of all the aggregation schemes significantly decreases. With Non-IID data, some of these aggregation schemes fail even in the complete absence of Byzantine clients. We conclude that the robustness of all the aggregation schemes is limited, highlighting the need for new defense strategies, in particular for Non-IID datasets.

description: The aim of this study was to examine the particle length, width, perimeter, and aspect ratio of calcium hydroxide powder using a flow particle image analyzer (FPIA). Five sample groups each with 10 mg of calcium hydroxide were mixed with 15 mL of alcohol and sonicated. Digital images of the particle samples were taken using the FPIA and analyzed with a one-way analysis of variance. The overall averages ± standard deviation among the five groups for particle length (μm), width (μm), perimeter (μm), and aspect ratio were 2.255 ± 1.994, 1.620 ± 1.464, 6.699 ± 5.598, and 0.737 ± 0.149, respectively. No statistical significance was observed among the groups for all parameters. When the total of 46,818 particles from all five groups were classified into the five length categories of 0.5-μm increments, there were significant differences in width, perimeter, and aspect ratio (all p values <0.0001). In conclusion, calcium hydroxide particles have a size and shape that may allow direct penetration into open dentin tubules.

description: Aim: To evaluate dentin tubule numerical density variations below the CEJ. Methodology: Three human non-carious permanent canines were sectioned parallel to the CEJ to obtain dentin disks 1 mm thick whose surfaces were 1 mm and 2 mm below the CEJ. Each disk was sectioned into quarters resulting in four segment locations: facial, lingual, mesial, and distal. The outer (PDL side) and inner (pulp side) surfaces of the specimens were shaped to expose dentin with SiC papers and polished. Numerical tubule density was determined from SEM images. All data were statistically analyzed using a three-way ANOVA. Results: The dentin tubule density (number/mm2) ranged from 13,700 to 32,300. Dentin tubule density was relatively uniform at 1 mm and 2 mm below the CEJ and increased by a factor of about two from the outer to the inner surface, which was significantly different (P < 0.0001). Conclusions: The tubule density variations at the cervical root did not present marked.
Seeing the Heiltsuk orthography from font encoding through to Unicode: A case study using convertextract

Year: 2018

description: Across the world's languages and cultures, most writing systems predate the use of computers. In the early years of ICT, standards and protocols for encoding and rendering the majority of the world's writing systems were not in place. The opportunity to deploy less-commonly used orthographies in cross-platform digital contexts has steadily increased since Unicode became the most widely used encoding on the web in late 2007 (Davis, 2008). But what happens to resources that were developed before Unicode standards became widespread? While many tools have been created to address this problem and other issues related to transliteration and character level substitutions, 1 this paper describes the process undertaken for the Indigenous and endangered Heiltsuk (Wakashan) language, and outlines a tool (Convertextract) that was designed to convert not only plain text, but also Microsoft Office (pptx, xlsx, docx) documents with the goals of updating and upgrading pre-existing digital textual resources to Unicode standards, and thus preserving the knowledge they contain for both the present and the future.

description: There was only one dental school in Malaysia until 1997 but five new schools have been established since 1998. This review provides information about dental education in Malaysia including; the history of dental education, the current dental school system and curriculum, and dental licensure. There are four public and two private dental schools in Malaysia. High school graduates are required to take the nationwide matriculation entrance examination or the Higher School Certificate (HSC) to apply for a dental degree programme. A five-year dental programme leads to the BDS or the DDS degree. National or state examinations are not required to practise dentistry. Currently, there are approximately 2,500 dentists, with a ratio of 1 dentist for every 10,000 people.
