There has been a dramatic improvement in the dental health of school schildren in the past 15 years. The proportion of children aged five to 12 years who have never experienced any dental decay increased nearly ten‐fold from 3·8% in 1961 to over 35% in 1974. The proportion of children with active dental decay at routine school examinations has fallen from 92% to 22%. These improvements are probably due to improved oral hygiene and diet in combination with the usage of fluoride. Almost certainly, the availability of fluoride both in tablet form and delivered through town water supplies has been the predominant factor. These very large reductions in the incidence of dental decay among children represent a modern triumph of preventive health care. Further improvements in dental health may be effected by the topical application of fluoride and reduced intake of refined sugar.

To determine whether fibre type affects the O2 exchange characteristics of skeletal muscle at the microcirculatory level we tested the hypothesis that, following the onset of contractions, muscle comprising predominately type I fibres (soleus, Sol, 86 % type I) would, based on demonstrated blood flow responses, exhibit a blunted microvascular PO2 (PO2,m, which is determined by the O2 delivery (Q̇O2) to O2 uptake (V̇O2) ratio) profile (assessed via phosphorescence quenching) compared to muscle of primarily type II fibres (peroneal, Per, 84 % type II). PO2,m was measured at rest, and following the rest‐contractions (twitch, 1 Hz, 2–4 V for 120 s) transition in Sol (n= 6) and Per (n= 6) muscles of Sprague‐Dawley rats. Both muscles exhibited a delay followed by a mono‐exponential decrease in PO2,m to the steady state. However, compared with Sol, Per demonstrated (1) a larger change in baseline minus steady state contracting PO2,m (ΔPO2,m) (Per, 13.4 ± 1.7 mmHg; Sol, 8.6 ± 0.9 mmHg, P < 0.05); (2) a faster mean response time (i.e. time delay (TD) plus time constant (τ); Per, 23.8 ± 1.5 s; Sol, 39.6 ± 4.3 s, P < 0.05); and therefore (3) a greater rate of PO2,m decline (ΔPO2,m/τ; Per, 0.92 ± 0.08 mmHg s−1; Sol, 0.42 ± 0.05 mmHg s−1, P < 0.05). These data demonstrate an increased microvascular pressure head of O2 at any given point after the initial time delay for Sol versus Per following the onset of contractions that is probably due to faster Q̇O2 dynamics relative to those of V̇O2.


Entrepreneurship is frequently promoted as an alternative to paid-employment and unemployment among young individuals. Numerous entrepreneurship education programs have arisen over the last decade in order to incentivize early start-ups among graduates. However, the long-term consequences of starting a professional career through entrepreneurship instead of following the standard entry path through paid-employment are often disregarded. In spite of the evidence that, on average, entrepreneurship tends to provide smaller, more volatile earnings that grow at a slower rate than paid-employment, the situation might be different when the comparison is done between young individuals with no relevant experience who are starting their careers. In this early version of our paper, we discuss several potential channels through which this initial decision may cause a persistent effect on lifetime earnings, such as wage signaling, timing of learning and human capital accumulation. We make use of the Integrated Database for Labor Market Research (IDA) from Statistics Denmark to explore the potential consequences of choosing entrepreneurship at entry in the labor market and to identify the presence of potential moderating factors. Preliminary results from instrumental variable estimations on a matched sample of graduates who start as paid-employees and graduates who become entrepreneurs suggest a negative effect for individuals in the last group. Although the effects seem to vanish over time, the earnings penalty is still significant ten years after entering the labor market. JEL Classification: J24, J62, L26.

Because of the socioeconomic status of the patients, direct resin composite laminate veneers were used to improve the esthetics of their maxillary and mandibular anterior teeth. Laminate veneers are restorations which are envisioned to correct existing abnormalities, esthetic deficiencies and discolorations This case report reflects the use of a innovative composite sculpting instrument ( OPTRA SCULPT PAD) for direct composite laminate in a patient who came with complaint of broken old laminate.


With molecular beam epitaxy we have grown Cry(BixSb1-x)2-yTe3 thin films with homogeneous distribution of Cr dopants and Curie temperature up to 77 K. The films with Cr concentration y ≥ 0.39 are found to be topologically trivial, highly insulating ferromagnets, whose conductivity can be tuned over two orders of magnitude by gate voltage. The ferromagnetic insulators with electrically tunable conductivity can be used to realize the quantum anomalous Hall effect at higher temperature in topological insulator heterostructures and to develop field effect devices for spintronic applications.


There is a growing body of research in economics that studies the consequences of time-inconsistent preferences. This paper introduces time-inconsistent preferences in a general equilibrium setting. We discuss how the standard notion of competitive equilibrium should be extended in order to allow for changes in intertemporal preferences. Depending on whether or not agents recognize that their intertemporal preferences change, agents are called sophisticated or naive. We present competitive equilibrium notions for economies with naive agents and economies with sophisticated agents and provide assumptions under which both types of equilibria exist. Time-inconsistency also raises conceptual issues on the appropriate notion of efficiency. Of particular importance is the way future intertemporal preferences are taken into account. An example shows that sophisticated equilibria may be less efficient than naive equilibria. We specify suitable conditions for which both types of equilibria satisfy appropriate efficiency notions.


To reveal how the ancient kiln has evolved along DongHe River Basin in Jingdezhen –Jiangxi Province of China, and further reflect the interaction of the political situation, the institutions and the natural environment, we create ancient virtual maps of study area and propose such constructs to unambiguously denote a integration system by combining the advantages of multi-agents, PSO and CA in time and space. We apply the system to model a dynamic interaction environment and conduct a series of spatial analyses of the land-use pattern from 1271 to 1554. Compared with model PSO-CA, the simulation result of this new model is of richer changing hierarchy and can better reflect the whole process from the first to the last firing. Meantime, the index Moran's I of simulation using the hybrid method is much closer to the actual Moran's I, which can better reflect the interaction between political environment and natural environment of different dynasties with the lack of ancient GIS spatial data.


Cognitive processes of moral 'moral rigidity' or moral absolutization play a central role in coordinating individuals around common prosocial prescriptions, in particular in group conflict and extremism. This short article proposes to view sacralisation and moral objectivism as the two complementary facets of humans' propensity to moral rigidity, and as having evolved as parsimonious solutions to the joint challenges of reliably signaling trustworthiness while protecting oneself from exploitation in ancestral coalitions.


This paper describes a method of fabricating high voltage Power Integrated Circuits using a dielectric isolation technique. The method consists of bonding silicon wafers with a silicon dioxide layer in between and forming the various circuit element by diffusion. This technique is used to fabricate a Power Integrated Circuit consisting of three transistors and six resistors with the following electrical characteristics: Collector- Base Voltage, V CBO = 450-500V @ 1 µa. Collector- Emitter Voltage, V CEO = 350-400V @ 1 µa. Collector- Base Capacitance, C OB = 3pf @ 20V. Frequency - Response, f T = 60 mZE @ 10 ma., 20V. Current Gain, h FE = 50 @ 30 ma., 10V. Emitter Resistor, R E = 260 ohms. Collector Resistor, R L =11K ohms. Isolation Voltage > 1000V. High reliability is achieved by the use of field electrodes and silicon nitride junction overcoat. One of the field electrodes is kept at the collector potential and this electrode prevents surface ion build-up and interrupts induced channels, which can occur beneath the interconnecting metallization. The other electrode overlaps the Collector - Base junctions, and it has the effect of increasing the voltage capability by reducing the radius effect. The silicon nitride overcoat prevents the migration of ionic contaminants into the passivating film.


Photoluminescence (PL) spectroscopy by excitation with 514.5 nm light at 4.2 and 77 K is applied to (GeS2)(80)(Ga2S3)(20): x mol % Er2S3 (x=0.3, 0.6, 0.9, 1.8, 2.1 and 2.4) glasses. The compositional dependence of the PL intensity is determined, and a quenching effect accompanied by the strongest absorption at 1.22 at % Er is established. The influence of temperature on the emission cross-section is investigated by deconvolution of the experimental spectra, and the observed fine features are explained on the basis of the energy level diagram of Er3+ ions. The distribution and changes of the structural units at higher Er concentrations are specified by Raman scattering, in the range 50-550 cm(-1).


Grid security is complicated on account of pervasive resource sharing and dynamic,multi-domains heterogeneous computing enverioment.The grid security infrastracture(GSI) is emerged for identify authentification,data confidentiality and integrity,but can not solute problems about access control well.Traditional model of access control can not satify security requerments of grid either.This paper describes a task-based access control model for computing grid,basing on the HUST grid.The model defines authorization steps,task status and system conditions,and pemissions can be dynamically controled.This model is enforced in computing grid experimental platform,and proved to be universal,flexible and extendable.


When Robert Juet gazed on the lower North River's shoreline in 1609, he noted that "the mountains look as though they contain some metal or mineral, for some of them are almost barren of trees, and what few trees do grow there are blighted." Further upriver he "found good land for growing wheat and garden herbs. Upon it were a great many handsome oak, walnut, chestnut, ewe and an abundance of other trees of pleasing wood. In addition, there was much slate and other good stone for houses." Sailing with Henry Hudson, Juet was among the first Europeans to view the river valley that would later bear his captain's name, although the ways in which subsequent travelers interpreted that landscape would change dramatically over the next four centuries. Juet and other seventeenth-century Europeans saw the land through the lens of economic development. Every tree, mountainside, meadow, or water body existed as a resource to be exploited, a potential area for economic activity.

Abstract : A captive testing technique capable of simulating aircraft maneuvers at high angles of attack has been developed and tested in the Aerodynamic Tunnel 16T of the Arnold Engineering Development Center (AEDC). The captive technique uses a closed loop system between wind tunnel, model, and computer. Use of the wind tunnel as an analog forcing function eliminates the requirement for a conventional static data matrix in motion simulation. Various high angle-of- attack maneuvers (rudder roll, aileron roll, wind-up turn, etc.) were generated with the captive system and show good correlation with flight data.


Millimeter wave (mmWave) beamforming is a vital component of the fifth generation (5G) new radio (NR) and beyond wireless communication systems. The usage of mmWave narrow beams encounters frequent signal attenuation due to random human blockages in indoor environments. Human blockage predictions can jointly improve the signal quality as well as passively sense human activities during mmWave communication. Human sensing using wireless fidelity (WiFi) systems has earlier been studied using receiver signal strength indicator (RSSI) signal level fluctuations based on distance measurements. Other conventional approaches using cameras, lidars, radars, etc. require additional hardware deployments. Current device-free WiFi sensing approaches use vendor-specific channel state information to obtain fine-grained human blockage predictions. Our novelty in this work is to obtain fine-grained human blockage direction predictions in mmWave spectrum, using a time series of RSSI measurements and build fingerprints. We perform experiments to construct a Human Millimetre-wave Radio Blockage Detection (HuMRaBD) dataset and observe human influence in different radio beam directions during each radio initial access procedure. We design a multi layer perceptron (MLP) framework to analyze the HuMRaBD dataset over coarse-grained and fine-grained mmWave blockage directions from static and dynamic human movements. The results show that our trained MLP-trained models can simultaneously sense multiple indoor human radio-blockage directions at an average F1 score of 0.84 and area under curve (AUC) score of 0.95 during mmWave communication.


:Phototropism plays an important role during early stage of plant development, and it is a favorable biological characteristic for plant organs to adapt environmental requirement. The recent advances in the studies of phototropism are reviewed in this paper:more and more evidences support Bruinsma-Hasagawa hypothesis that tissues within the plant are affected by the Pfr gradient and express growth redistribution; Fluence-response studies of phototropism indicate that fPIPP and TDP are general types of multiple response types of phototropism; several photoreceptors involving phototropism have been characterized; four genetic loci affecting phototropism have been identified by mutants of Arabidopsis thaliana.


Er-doped silicon-rich silicon nitride (SRN) films were deposited on silicon substrate by an RF magnetron reaction sputtering system. After high temperature annealing, the films show intense photoluminescence in both the visible and infrared regions. Besides broad-band luminescence centered at 780 nm which originates from silicon nanocrystals, resolved peaks due to transitions from all high energy levels up to 2H11/2 to the ground state of Er3+ are observed. Raman spectra and HRTEM measurements have been performed to investigate the structure of the films, and possible excitation processes are discussed.


Absolute rate constants for the reaction of hydrogen atoms with acetaldehyde were obtained over the temperature range 298–500 K using the flash photolysis–resonance fluorescence technique. The rate constants gave the Arrhenius expression k= (2.23±0.39) ×10−11 exp(−3300±120/1.987T) cm3 molecule−1 s−1. Independent experiments with a discharge flow system employing resonance fluorescence detection of H gave a room temperature rate constant in agreement with this equation. These results are discussed and comparisons are made with previous work and theoretical predictions.


Cyclotrons in combination with ECR ion sources provide the ability to accelerate ''cocktails'' of ions. A cocktail is a mixture of ions of near-identical mass-to-charge (m/q) ratio. The different ions cannot be separated by the injector mass-analyzing magnet and are tuned out of the ion source together. The cyclotron then is utilized as a mass analyzer by shifting the accelerating frequency. This concept was developed soon after the first ECR ion source became operational at the 88-Inch Cyclotron and has since become a powerful tool in the field of heavy ion radiation effects testing. Several different ''cocktails'' at various energies are available at the 88-Inch cyclotron for radiation effect testing, covering a broad range of linear energy transfer and penetration depth. Two standard heavy ion cocktails at 4.5 MeV/nucleon and 10 MeV/nucleon have been developed over the years containing ions from boron to bismuth. Recently, following requests for higher penetration depths, a 15MeV/nucleon heavy ion cocktail has been developed. Up to nine different metal and gaseous ion beams at low to very high charge states are tuned out of the ion source simultaneously and injected together into the cyclotron. It is therefore crucial to balance the ion source very carefullymore » to provide sufficient intensities throughout the cocktail. The paper describes the set-up and tuning of the ion source for the various heavy ion cocktails.« less

ABSTRACT A Center for Research Libraries working group on cooperative collection development in the sciences and technology identified the geosciences as a domain whose current and historical publications make ideal candidates for a digitization demonstration project, due to their utility and the diverse nature of their text, tables and images. State geological surveys engage in some of the most important and practical fieldwork undertaken by geologists. State geological surveys and maps have had a critical impact in the discovery, exploration, use and conservation of natural resources. As a consequence, close to 2,000 selected publications from the states of Illinois, Pennsylvania, Texas and Wyoming were chosen for the scope, quality and variety exhibited in them. The eighteen-month digitization pilot project will, upon conclusion, design a self-sustaining model for a continuation program.


Nonprotein amino acid furanomycin was found to bind with Escherichia coli isoleucyl-tRNA synthetase (IleRS) almost as tightly as the substrate L-isoleucine. The conformation of furanomycin bound to the enzyme was determined by NMR analyses including the transferred nuclear Overhauser effect method. The conformation of IleRS-bound furanomycin was similar to that of L-isoleucine, although the chemical structure of furanomycin is unlike that of L-isoleucine. By E. coli IleRS, E. coli tRNA"" was charged with furanomycin as efficiently as with L-isoleucine. Furthermore, furanomycyl-tRNA"" was bound to polypeptide chain elongation factor Tu as tightly as isoleucyl-tRNA"'. Furanomycin was found to be incorporated into j3lactamase precursor by in vitro protein biosynthesis. A newly designed amino acid will probably be incorporated into proteins, provided that the new amino acid takes a similar conformation as a protein-constituting amino acid in the active site of an aminoacyltRNA synthetase.


This book provides a comprehensive and historically rich account of the sudden rise of Jean-Paul Sartre (1905–1980) as a public intellectual in France in the mid-1940s. Written by Patrick Baert, Professor of Social Theory at Cambridge, the case of Sartre is in fact but an application of a new sociological theory of intellectuals that revolves around notions of positioning, networks and conflict. This theory is the subject of the last two chapters and can be read separately from the others. By ''positioning'', Baert means the process by which certain features are attributed to an individual or a group. Intellectual interventions, whether through writing or speaking, always involve positioning. Positioning, in turn, is not a one-off event but an ongoing process that involves more or less complex intellectual and political networks. Team membership is crucial, Baert notes, because positioning rarely goes uncontested. Intellectuals might be able to position themselves positively and effectively for a certain period of time, but eventually rival intellectuals will challenge them, portraying them as outdated, insignificant or outright erroneous. Sartre's case is a good illustration of this as, from early on, he was the subject of criticism from various quarters and struggled to shed accusations of being either a bourgeois thinker or a nihilist. The main focus of the book, however, is not on Sartre's demise but on his ascent to stardom. In five detailed chapters, Baert discusses Sartre's intellectual interventions, the network of friends and colleagues in which he operated and the broader context of France in the mid-1940s to explain the origins of ''the existentialist moment''. The first chapter presents a useful overview of the period of the German occupation of France, between 1940 and mid-1944. Baert focuses upon how the occupation and collaboration affected the French cultural scene, deepening existing cleavages within the intellectual community. The second chapter looks at the debates around the trials of collaborators, following the decree of 30 May 1944 that stipulated that writers and artists who had collaborated with the enemy would be purged. These trials triggered immense media interest. The most controversial trial was that of Robert Brasillach, the editor of the fascist Je suis partout. The trial took only one afternoon – 19 January 1945 – and resulted in Brasillach's guilty verdict and eventual execution. Baert interprets this purge as an attempt by French society to come to terms with the cultural trauma of the occupation: writers were the object of exemplary punishment given the mythological status that literature had for the French cultural establishment. The third chapter discusses the intellectual debates around the purge, in which the notion of responsibility became central to the vocabulary used by former Resistance intellectuals to express the trauma of the war. This is also the period when, between the autumn of 1944 and the summer of 1945, Sartre began Acta Sociologica 1–2 a The Author(s) 2016 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav asj.sagepub.com

The production of polyhydroxyalkanoates (PHAs) by Bacillus megaterium using industrial residues, crude glycerol from biodiesel synthesis and rice hull hydrolysate (RHH), as low-cost carbon sources was investigated. The experiments were conducted by shaking flasks at 30 °C and 180 rpm up to 72 h. The extraction of PHA was carried out using sodium hypochlorite to make its recovery more environmentally friendly by avoiding organic solvents (chloroform). The yields of PHA varied depending on the extraction method. A total of 33.3% (w·w−1) (mixing chloroform: sodium hypochlorite) and 52.5% (w·w−1) (sodium hypochlorite only) were obtained using glycerol and glucose as a carbon source, respectively. Preliminary experiments using RHH as a carbon source Indicated a yield of PHA of 11% (w·w−1) (chloroform). The PHA produced had thermal properties, such as transition temperature, similar to the commercial polyhydroxybutyrate (PHB).

This study deals with the design and development of a Yellow Hybrid Corn Optimized Nutrient e-Advisor, a PC-based decision support tool to enhance the Philippine Nuclear Research Institute's electronic spreadsheet calculation of recommendations. The existing system does not have an irrigation advisory, lacks plant population computation, user's Recommended Rate (RR) of Nitrogen-Phosphorus-Potassium (NPK) and the user's cost of the possible combination of inorganic fertilizers. The e-Advisor implemented the modified Mitscherlich equation developed and tested by Rallos et al. The modified equation can also calculate the crop's agronomic N-use efficiency by using the established efficiency indices from several conducted field trials. It takes the following parameters as inputs: field location, soil type, soil analysis results, cultivar, field size, potential yield, target yield and date of planting. It generates the following recommendations: RR in kg per hectare and RR in kg per user's area of NPK nutrient needed based on user's field characteristics, location's climatic type, lime requirement of the field, possible combinations of inorganic fertilizers and their costs, and irrigation advisory. The application was developed using C#, a multi-paradigm and an object-oriented programming language. Based on the acceptability testing and evaluation using ISO 9126, the application has been found out to be generally acceptable by 52 corn farmers, commercial corn growers, researchers, scientists, provincial/municipal agriculturists, agricultural technicians, faculty, students, and soil laboratory personnel. It is highly recommended that this application be implemented in both mobile and web-based platforms and other adaptable environments to make it portable and more accessible. The integration of corn pest and diseases diagnosis is also recommended.


Abstract Most people will have been exposed to some aspect of the debate about the Athabasca Oil Sands in North-Eastern Alberta and the significant role that the oil sands are expected to play in supplying conventional fossil fuels. Part of the bitumen is recovered from mines and part is recovered from in situ projects utilizing the Steam Assisted Gravity Drainage Process (SAGD). SAGD utilizes a considerable amount of steam, that is injected into geological formations. Hot water, bitumen and some vapour are recovered from the production wells. With significant steam generation, transmission and injection, there is the very real possibility of condensation induced water hammers. There have been a number of catastrophic failures to date. The intent of the paper is to provide interesting background information on the in situ oil sands industry. More importantly, to show some interesting and broader applications of thermalhydraulics developed in the nuclear industry. The expertise developed may have potential markets, with some adaptation, to the oil sands industry. Finally, there has been some discussion about using nuclear power for steam generation in the oil sands.

Some investigators have linked states of happiness to beneficial health effects, although the mechanisms underlying the association remain elusive. These researchers conducted a novel social-network analysis to examine whether social contagion promotes happiness. Twenty years of data came from 4739 participants in the longitudinal Framingham Heart Study, who had 53,228 social ties with other study participants. Happiness was …


In this paper, we propose to use speech modulation features for robust nonnative accent detection. Modulation spectrum carries long term temporal information of speech and may discriminate accents of native and nonnative speakers. For each speech segment to be tested, we extract a 10 dimension feature vector from modulation spectrum and use it for model training and testing. The proposed modulation features are compared with other popular features such as pitch and formant on a nonnative French accent detection task. Results show that the modulation features produce good detection performance and are quite robust to channel distortions. In addition, when combine test scores of modulation features and pitch features, performance is further significantly reduced. The best equal error rate is 13.1% by fusing pitch and modulation-based systems.


In the coming years the European Common Agricultural Policy will be modified through the introduction of a Greening Payment. A significant share of the subsidies will in future be linked to rewarding farmers for the provision of environmental public goods. In particular, the European farmers will be subjects to maintain "ecological focus area" across their farms. As reservoirs of biodiversity, water bodies are one of the natural resources targeted by this measure. Members' states need therefore a very high resolution mapping of water bodies to monitor precisely their presence and extent variations. This research proposes a semi‐automatic method to update the regional water bodies map. Furthermore, this accurate map can be use as a validation dataset to support at larger scale mapping.


Consideration of a fully coupled lamination model with eddy currents and magnetic hysteresis in standard finite element (FE) models is prohibitively expensive in terms of implementation effort, memory requirements and computation time. Hence this paper utilizes an algebraic approximation of the lamination model as a conventional constitutive relationship in two-dimensional FE simulations of rotating electrical machines. Extraction of model structure and parameters of the parametric model as well as iterative adaption of the homogenized FE characteristic are presented. This pragmatic approach turns out to be quite accurate and efficient simultaneously allowing for refinement of the pre-determined parametric expression by iterating between the fully coupled lamination model and the macroscopic model.


Many existing dams and river structures require modification, and new structures may need to include designs to allow safe white water activities. The basic problem is safety, with a long list of other concerns including expense, stability, technical difficulty, utility or hydropower relationships, aesthetics and aquatic passage. The fundamental issue with regard to safety relates to the formation of dangerous hydraulic jumps including submerged jumps, of the type with reverse (or upstream) surface current and very abrupt vertical differentials. Recreational craft, safety devices and people are likely to be trapped in certain jumps. Once involved, escape from such a man-made feature is difficult because of the uniformity (linearity) of the structure.


A stage is provided to support stably a glass panel having various sizes by improving an arrangement of a plurality of pads. A plurality of pads(10) are formed to support a substrate. A mobile supporting unit(20) supports movably the pads to maintain a regular interval between the pads so that the pads approach each other or are separated from each other. The pads include a pair of fixing pads(10a) selected from the pads, a pair of driving pads(10b) selected from the pads, and a plurality of driven pads(10c). The driving pads positioned apart from the fixing pads. The driven pads are arranged between the fixing pads and the driving pads.


The human race wants to live peacefully. The society to be professional and mankind must be prevalent for long time. Unfortunately, the crime against the human society is rapidly increasing day by day. Crime against kids, women and elders are increase drastically. So, in this research work a dynamic mode CRIMFIND is developed. It used the rule-based algorithm to predict the crime. The information provided by this model help to stop the criminal activity. This approach is compared with BCO and Rough set-based classification model the experimental results show the proficiency of this approach.


Jacobsen, S.B. and Wasserburg, G.J., 1981. Transport models for crust and mantle evolution. In: R.E. Zartman and S.R. Taylor (Editors), Evolution of the Upper Mantle. Tectonophysics, 75: 163-179. The exact solutions for the isotopic compositions and the concentrations of two models for mantle-rust evolution are given for arbitrary rates of crustal growth and of backflow to the mantle. In Model I, continents are derived by melt extraction over the history of the earth from undepleted mantle. In Model II, new additions to the continents are derived from a mantle reservoir which becomes increasingly depleted through time by repeated extraction of melts. The key parameters are the chemical fractionation factors for crustal growth and refluxing and the integrated fractional mass removal rates from the crust and the mantle. The relationships between the mean age of the mass of the continents and the isotopic parameters are given. The models suggest that the pre-Archean era (prior to 3.8 AE) was dominated by rapid refluxing of crust to the mantle which during the early Archean gave way to a regime where transport from the mantle to the crust substantially dominated over refluxing of crust to the mantle. The mean age of the mass of the continents appears to be -1.8 AE. Even for small amounts (-10%) of refluxing Model II shows that highly incompatible elements have very short residence times in the mantle. Mass balance considerations implies that the continents were derived from only a small fraction (-30%) of the mantle.


Male worms of Ancylostoma braziliense, A. ceylanicum, A. kusimaense, A. malayanum, A. duodenale, A. caninum, A. tubaeforme, Agriostomum vryburgi and Cyclodontostomum purvisi have the external appendages beside the anogenital aperture. These anogenital structures are morphologically similar and are assumed to be homologous among the species with three pairs of teeth or more. In hookworms with two pairs of teeth, the anogenital structures are complex. Anogenital features can be used as a taxonomic character in separating the species.


The optimal tilt angle of solar photovoltaic panel in Ilorin, Nigeria was determined. The solar panel was first mounted at 0o to the horizontal and after ten minutes, the voltage and current generated with the corresponding atmospheric temperature were recorded. The same procedure was repeated for 2o to 30o at a succession of 2o at ten minutes time interval over the entire measurement period. The result obtained shows that the average optimal tilt angle at which a solar panel will be mounted for maximum power performance at fixed position in Ilorin is 22o. This optimum angle of tilt of the solar panel and the orientation are dependent on the month of the year and the location of the site of study.


In this multi-year project, we are investigating the relative impact of engineering design formative assessment on student achievement with respect to science and engineering concepts and practices. We have created an engineering design formative assessment task for middle school students that can be integrated into existing science curricula. The task engages students in two virtual environments as they redesign a solar still to more effectively provide drinking water for families with access to ocean water but limited access to a reliable source of drinking water. We are using a pre/posttest design as a measure of the impact of the formative task on student achievement and will compare results between intervention and comparison classes across all students and for identified subgroups of students. A detailed discussion of the engineering design formative assessment task and the two virtual environments is provided. Discussion of other aspects of the project is limited to a general overview as we are in the early stages of data collection for this ongoing project.


Can children be induced by contradictory evidence to abandon their belief in concrete-operational concepts? Miller (1971) reviewed nine studies directed to the issue of "extinction of conservation." Since that review, 11 more studies of the extinction of Piagetian con cepts have appeared; in addition Strauss (1972, 1974) and Brainerd (1973) have exchanged opposing views on the current state of the literature. In Strauss's view, extinction, in the sense of a genuine re turn to an earlier level of functioning, is infrequent. Much of the ap parent extinction that has been reported can be attributed to problems of measurement. In Brainerd's view, extinction occurs fairly readily, but its probability depends on the developmental level of the concept in question. Specifically, the claim is that developmentally early con cepts are more difficult to extinguish than developmentally later ones. The purpose of this paper is to reconsider some of the issues raised by Miller (1971) in the light of the more recent evidence and commentary. Several themes underlie the paper. A first is that ex tinction studies speak to central claims in Piaget's theory concerning the origins and nature of operational knowledge. A second is that such studies are very difficult to do, and are often not done very well. A third is that neither Strauss nor Brainerd provides a satisfactory picture of the current state of the evidence.


The purpose of this study was to evaluate a contact-based educational symposium designed to reduce mental health– related stigma in journalism students. Repeated surveys conducted before (n = 89) and again after the intervention (n = 53) were used to assess change. The estimated average response rate for each survey was 90%. The instrument, adapted from prior research, contained items pertaining to stereotypical content, attitudes toward social distance and feelings of social responsibility (Cronbach's alpha =.74).


Doppel is a recently found PrP-like protein, and its first structure showed 25% identity with the C-terminal two-thirds of PrP . Doppel is upregulated in the CNS of some PrP-deficient lines of mice developing late-onset ataxia, suggesting that Doppel may provoke neurodegeneration. It is presumed that Doppel should play an important role similar to PrP in the pathogenesis of Prion diseases.


ABSTRACT The emission of vapors from solid samples of Pentaerythritol Tetranitrate (PETN) in a flow of nitrogen from ~20 to 140°C was characterized using atmospheric pressure chemical ionization mass spectrometry equipped with a 63Ni ion source. Mass analysis of ions derived from vapors from military grade PETN at room temperature, without deposition from solution, included only NO3 − (62 Da) and HNO3 ·NO3 − (125 Da) and were attributed to residual levels of nitric acid in the PETN solid. The vapor level of HNO3 persisted until 80°C and after this declined asymptotically to background levels; ions observed above 110°C were nitrate adducts of molecular PETN including (PETN)n ·NO3 − with mass values of 378 Da (n = 1) and 695 Da (n = 2). Subsequent reheating of the PETN solid caused an increase release of nitric acid and formation, above 140°C, of the same nitrate adducts of PETN,, consistent with thermal degradation of some PETN to nitric acid. A commercial handheld ion mobility spectrometer was used to sample airborne vapors from solid PETN in an open container and heated in ambient air. The ion mobility spectra showed that ionization chemistry was rapidly transformed from O2 − to NO3 − which persisted indefinitely and produced ion above 80°C with Ko values of 1.48, 1.21, 1.15, and 1.10 cm2/V s. These relatively low-mobility peaks were attributed to cluster ions of nitrate with nitric acid and molecular PETN generated from thermal decomposition and some vaporization of solid PETN. Persistence of nitrate as a reactant ion in the handheld analyzer suggested a need for specialized designs and materials for such explosives vapor measurements.


Abstract In efforts to protect my sanity while learning computational arts at a Western institution, I have established a subversive anti-conformist strategy where I activate the ideologies of Hood Feminism, Negritude and Poetics to survive. Hood Feminism explores Black womanhood in a different modality from Black feminist studies. I am activating Hood Feminism in its intended form as praxis of women of color who survive without access to resources and privilege. These are women who survive by all means necessary against the propagation of toxic ideologies of Western society. I am activating Negritude as a way of maintaining positionality to the desired behavior that is institutionally imprinted on students, especially students of color. Negritude is a way for me to constantly reject the efforts of the conformist hegemonies by connecting with what it means to embody Blackness. Poetics materializes as a method of connecting with computation and other students in a meaningful way.


Italian planning seems to be underestimated outside Italy and the cause for this is unclear. There may be two possible explanations. On the one hand, it could be argued that Italian planning is ignored internationally as the consequence of a lack or of a small number of international articles about it published in international journals. On the other hand, it may be the perception that international scholars have of it, which in part depends on the articles published, but which means that there have been few attempts to spread knowledge concerning the practice of planning in Italy. This article provides a brief account of the development of Italian planning over time and seeks to emphasise the peculiarities of the discipline in Italy and to discuss what areas of study offer the best potentials for further studies either on a comparative basis with other countries or Italy focused.


As innovation activity within cooperation, network, and openness is paid attention, open innovation that reinforces competitiveness of innovation activity using various inside and outside sources, was introduced. In this study, the innovation efficiency of Korean manufacturing and service industry is measured and relationship with openness is analyzed. In comparative analysis among observed firms with relative efficiency measurement, it should be evaluated under identical conditions by ruling out external environmental influences. Therefore a three-stage approach is applied to estimate net innovation efficiency that excludes advantage or disadvantage from environmental factors. This study estimates net innovation efficiency that terminates effects of external factors placed in out of operational control of firm using the three-stage approach. It aims to improve reliability of research because observed firms are evaluated under identical conditions. Furthermore, the results show the degree of openness affects innovation efficiency positively in manufacturing sector. It implicates the needs of policy that encourages manufacturing firms to cooperate with external facilities actively.

Service-Oriented Architecture enables the composition of loosely coupled services provided with varying Quality of Service (QoS) levels. Given a composition, finding the set of services that optimizes some QoS attributes under given QoS constraints has been shown to be NP-hard. Therefore, heuristic algorithms are widely used, finding acceptable solutions in polynomial time. Still the time complexity of such algorithms can be prohibitive for real-time use, especially if the algorithms are required to run until they find near-optimal solutions. Thus, we propose a heuristic approach based on Hill-Climbing that makes effective use of an initial bias computed with Linear Programming, and works on a reduced search space. In our evaluation, we show that our approach finds near-optimal solutions and achieves a low time complexity.


PAHs are an environmental concern because of their reduced bio-availability. Biodegradation via microorganisms who possess required enzyme systems for the breakdown of recalcitrant compounds is one of the best options available, as the end products are non toxic. Stenotrophomonas koreensis AK-1 (GENBANK:KP145677.1) a novel organism, was isolated from dust on  dark leaves of Ficus religiosa ( Peepal tree) ,which could aerobically degrade various aromatichydrocarbons(Phenol,Benzene,Aniline,Xylene,Anthracene,Naphthalene). The degradation was estimated by analytical techniques like U.V visible spectroscopy, Reverse Phased HPLC and Phenol estimation titration. The key feature of the organism was its ability to degrade phenol and phenolic compounds aerobically. It was observed that genes for enzyme complex required for degradation were constitutive and not plasmid borne, as no plasmids were observed on Agarose gel electrophoresis. The organism, thus, holds potential for further application in field of biodegradation of PAHs.


The high number of Distributed Denial of Service (DDoS) attacks have demanded innovative solutions to guarantee reliability and availability of internet services. In this sense, different methods have been used to analyze network traffic for denial of service attacks, such as neural networks, decision trees, principal component analysis and others. However, few of them explore dynamic features to classify network traffic. This article proposes a new method, called DDoSbyAQR,that uses the recurrence quantification analysis based on the extraction of dynamic characteristics and an adaptive clustering algorithm (A-kmeans) to perform better classification of the attack network traffic. The experiments were done using the CAIDA and UCLA databases and have demonstrated ability to increase the accuracy (98.41%) of DDoS detection.


A mixture of n-dodecane and m-xylene is investigated as a diesel fuel surrogate for compression ignition engine applications. Compared to neat n-dodecane, this binary mixture is more representative of diesel fuel because it contains an alkyl-benzene which represents an important chemical class present in diesel fuels. A detailed multi-component mechanism for n-dodecane and m-xylene was developed by combining a previously developed n-dodecane mechanism with a recently developed mechanism for xylenes. The xylene mechanism is shown to reproduce experimental ignition data from a rapid compression machine and shock tube, speciation data from the jet stirred reactor and flame speed data. This combined mechanism was validated by comparing predictions from the model with experimental data for ignition in shock tubes and for reactivity in a flow reactor. The combined mechanism, consisting of 2885 species and 11754 reactions, was reduced to a skeletal mechanism consisting 163 species and 887 reactions for 3D diesel engine simulations. The mechanism reduction was performed using directed relation graph (DRG) with expert knowledge (DRG-X) and DRG-aided sensitivity analysis (DRGASA) at a fixed fuel composition of 77% of n-dodecane and 23% m-xylene by volume. The sample space for the reduction covered pressure of 1 – 80 bar, equivalence ratiomore » of 0.5 – 2.0, and initial temperature of 700 – 1600 K for ignition. The skeletal mechanism was compared with the detailed mechanism for ignition and flow reactor predictions. Finally, the skeletal mechanism was validated against a spray flame dataset under diesel engine conditions documented on the Engine Combustion Network (ECN) website. These multi-dimensional simulations were performed using a Representative Interactive Flame (RIF) turbulent combustion model. Encouraging results were obtained compared to the experiments with regards to the predictions of ignition delay and lift-off length at different ambient temperatures.« less

Background In posttraumatic stress disorder (PTSD), the traumatic event is often re-experienced through vivid sensory fragments of the traumatic experience. Though the sensory phenomenology of traumatic memories is well established, neural indications for this qualitative experience are lacking. The current study aimed at monitoring the oscillatory brain activity of PTSD patients during directed and imaginal exposure to the traumatic memory using magnetoencephalography (MEG), in a paradigm resembling exposure therapy. Methods Brain activity of healthy trauma-exposed controls and PTSD participants was measured with MEG as they listened to individualized trauma narratives as well as to a neutral narrative and as they imagined the narrative in detail. Source localization analysis on varied frequency bands was conducted in order to map neural generators of altered oscillatory activity. Results PTSD patients exhibited increased power of high-frequency bands over visual areas and increased delta and theta power over auditory areas in response to trauma recollection compared to neutral recollection, while controls did not show such differential activation. PTSD participants also showed abnormal modulation of lower frequencies in the medial prefrontal cortex. Conclusions Elicitation of traumatic memories results in a distinct neural pattern in PTSD patients compared to healthy trauma-exposed individuals. Investigating the oscillatory neural dynamics of PTSD patients can help us better understand the processes underlying trauma re-experiencing.


This paper deals with a percussive rock surface crusher driven with a solenoid. For a future lunar exploration, an unmanned mission is planned to investigate rock samples automatically. The weathered rock surface should be removed and smoothed to investigate its structure and composition precisely. A solenoid was used to vibrate a tool bit made of tungsten carbide because of its long stroke and large generative impulsive force. The crusher measures 59 mm × 60 mm × 129 mm and weighs 490 g. The specimen was reciprocally fed with a slider-crank mechanism in the horizontal direction. The peak of the generative force was 170 N driven by a sinusoidal voltage of 50 Hz. In order to decrease the temperature rise at the solenoid, heat should be conducted to the structure, especially in vacuum. Smoothing basalt was demonstrated in air and vacuum environment.


Query expansion is one of most important technique in information retrieval where provides a series of methods to reform the query applying to retrieval in order to extract result more precisely. In the past, there are many kind of trails on this technique in different perspective. In this project, I'll try to implement query expansion with topic models, where using topic modeling technique to help us to do query expansion. In this project, I implement the Relevance Model (RM) approach by topic model LDA, and compare the retrieval result with baseline and naive query expansion result.


To investigate the construction of association culture, this study used a multi-stage sampling survey design, which is a cost- and time-effective probability sampling method. The research sample consisted of 858 Chinese college students who took part in a questionnaire study. The authors innovatively constructed an index system that can objectively evaluate the satisfaction of association construction and used the principal component method to descend to construct the comprehensive indicator of satisfaction. The authors excavate the key influencing factors of association culture construction and finally summarize them into four factors, which are internal construction factor of the association, resource allocation factor of the association, school management factor of the association and instructor factor of association. Finally, regression analysis indicated that the internal and material building of associations be prioritized, and the school authorities should give more financial support and create a relaxed environment for the culture development of associations.


The amplitude-dependent internal friction which is due to dislocations oscillating in the lattice is described in terms of dislocation mobility, under the condition that the motion of dislocation is limited by tension forces, as will be the case at low frequencies. It is shown that the friction increases as the frequency increases and that it decreases as the amplitude increases. These results are in contrast to those obtained before for the internal friction at high frequencies, where the internal friction increases with the amplitude and has an inverse frequency dependence. Comparison with available data of low frequency internal friction on copper and α-brass shows that the line-tension limited motion accounts for the observed results.


Background Thyroid dysfunction (hypo and hypertiroidism) has been described among patients with connective tissue diseases, particularly in patients with systemic lupus erythematosus (SLE) and primary Sjögren syndrome (PSS). Also a high prevalence of anti-thyroid antibodies (ATA) has been found in these patients. Objectives To study:1) Thyroid function and morphology in a population of SLE and PSS patients; 2) To evaluate the prevalence of ATA in these patients; 3) To correlate clinical manifestations with laboratory data. Methods We studied serum levels of thyroid hormones, TSH, anti-thyroglobulin and anti-microssomal antibodies in 70 consecutive patients (50 with SLE and 20 with PSS), followed in our department. We performed thyroid ultrasound in all patients. Patients were asked about signs and symptoms related to the manifestations of thyroid dysfunction. ResultsAbstract FRI0141 Table 1 Females (%) Age Years of disease Abnormal thyroid morfology (%) Thyroid autoantibodies (%) Thyroid disfunction (%) Assymptomatic thyroid disease (%) SLE 96 40 ± 13 9 ± 8 38 12 18 56 PSS 95 45 ± 12 7 ± 6 40 25 20 75 Conclusion In this group of patients we found a high prevalence of thyroid morphology abnormalities and thyroid dysfunction. In both groups less than half of the patients with thyroid dysfunction presented related symptoms. These results suggest that all SLE and PSS patients should be routinely screened for thyroid disease even in the absence of clinical manifestations.


In the process of stereo super-resolution reconstruction, in addition to the richness of the extracted feature information directly affecting the texture details of the reconstructed image, the texture details of the corresponding pixels between stereo image pairs also have an important impact on the reconstruction accuracy in the process of network learning. Therefore, aiming at the information interaction and stereo consistency of stereo image pairs, a cross-view attention interaction fusion stereo super-resolution algorithm is proposed. Firstly, based on parallax attention mechanism and triple attention mechanism, an attention stereo fusion module is constructed. The attention stereo fusion module is inserted between different levels of two single image super-resolution network branches, and the attention weight is calculated through the cross dimensional interaction of the three branches. It makes full use of the ability of single image super-resolution network to extract single view information and further maintaining the stereo consistency between stereo image pairs. Then, an enhanced cross-view interaction strategy including three fusion methods is proposed. Specifically, the vertical sparse fusion method is used to integrate the interior view information of different levels in the two single image super-resolution sub branches, the horizontal dense fusion method is used to connect the adjacent attention stereo fusion modules and the constraint between stereo image consistency is further strengthened in combination with the feature fusion method. Finally, the experimental results on Flickr 1024, Middlebury and KITTI benchmark datasets show that the proposed algorithm is superior to the existing stereo image super-resolution methods in quantitative measurement and qualitative visual quality while maintaining the stereo consistency of image pairs.


Specific surface areas have been calculated for different types of cellulose: fibers, sawdust of conifers in the form of flakes and sawdust of forest coniferous trees of irregular shape, wood flour. The dependence of the structural and mechanical properties of the material on the type of pulp: shrinkage, tensile strength and elongation have been studied. It is shown that the required tensile strength of the material (16.3-22.5 MPa) is achieved using the fiber form cellulose. We designed the composition of inert material based on cellulose and polyvinylacetate providing the processing conditions identical with the standard analog by the method of filtration molding and physicomechanical properties and enabled verification of serviceability of functioning of the equipment.


Viviani's Theorem, discovered over 300 years ago, states that inside an equilateral triangle, the sum of the perpendicular distances from a point P to the three sides is in dependent of the position of P (and so equals the altitude of the triangle). Incidentally, the person for whom this theorem is named is Vicenzo Viviani (1622-1703), a pupil of both Galileo and Torricelli. The theorem can easily be proved: Let s and h be the side length and the altitude of the equilateral triangle AABC, let P be any point inside the triangle, and let du d2, and d3 be the three distances from P to the sides of the triangle. Since AABC is made up of APAB, APBC, and APCA, it follows that \sh = \sdx + \sd2 + \sd3, and so d\ + d2 + d$ = h, which proves the theorem. Samelson [1] gave a different proof, one that uses vectors, something we will return to shortly. This motivated us to consider the following question: Does the converse of Viviani's Theorem also hold? That is, if the sum of the distances from a point inside a triangle to the three sides is constant, must the triangle be equilateral? An affirmative answer can be obtained just by considering different points near one vertex of the triangle. However, by using vectors (in the style of Samelson), we can get a stronger result.


A comparison is made between vibrational transition probabilities calculated by use of the WKB approximation with those obtained from other methods. For Cl2–Cl2, the transition matrix element for a purely repulsive exponential potential is within 1.5% of the Jackson–Mott exact value over the energy range from 1500k–3900k. For a "shifted exponential" potential, the WKB matrix element agrees satisfactorily with the exact value and with the Hartmann–Slawsky approximation at higher energies. It is also shown that the WKB matrix element for a Morse potential is larger than the Lennard‐Jones (12–6) matrix element by a factor of 1.3–1.5 over the energy range from 900k–3900k for Cl2–Cl2. Both for the exponential and inverse‐law potentials, the inclusion of attractive forces in the calculation leads to significantly larger matrix elements. Application of the WKB method to the calculation of the collision numbers of Cl2–Cl2 and O2–O2 gives results within a factor of about 2 of the experimental data up to temperatur...


Following the establishment in 2005 of an Intergovernmental Coordination Group for the Tsunami Early Warning and Mitigation System in the North Eastern Atlantic, the Mediterranean and Connected Seas (ICG/NEAMTWS), parallel to similar efforts in the Pacific and Indian Oceans and in the Caribbean, the Intergovernmental Oceanographic Commission of UNESCO (IOC) has engaged in the development and coordination of multi-hazard strategies and interoperable systems for tsunamis and other sea-level related hazards in consultation, coordination and cooperation among all stakeholders with tsunami and related ocean hazard mandates. As a result of this approach, a series of guidelines have been compiled by an international group of experts working under the auspices of the IOC. The group included specialists in the fields of sea-level related hazards, marine meteorology, vulnerability and risk in respect of natural hazards, early warning and preparedness, risk mitigation, and coastal zone management. These guidelines aim to assist policy makers and managers in the reduction of the risks to coastal communities, their infrastructure and service-providing ecosystems from tsunamis, storm surges and other coastal hazards within the phased framework of Integrated Coastal Area Management (ICAM). As a context for the procedures presented in the Guidelines, the full framework of the ICAM process is used. This shows how the assessment of coastal hazards and the mitigation of the risks in respect of those hazards can be embedded within the four phases of ICAM, each with its respective procedural steps: preliminary identification; preparation; implementation; consolidation, replication and expansion. Each step is described – including its purpose, its key considerations, the management challenges that it poses and its anticipated outputs. A description of the physical features of the sea-level related coastal hazards is followed by approaches to assess the vulnerability of the hazard receptors – the coastal community and its supporting systems. The integration of the hazard probability and vulnerability (including preparedness) assessments produces assessments of the risks to the various community dimensions (human and social, physical (buildings) and economic and environmental) in respect of the identified hazards is then dealt with. These assessments take into account deficiencies in preparedness at the institutional level. The guidance in the management of the assessed risks within the framework of ICAM aims to enhance public awareness of the risks and to improve the resilience of coastal communities for coping in emergency situations of the threat or impact of a hazard event. Finally, the guidelines describe the options for structural and non-structural responses within the framework of ICAM for the mitigation of the assessed risks by strategic management


The essay discusses the criteria available in Peru's environmental impact assessment regime for mandatory modification of environmental impact studies as a result of the modification of the underlying project. The paper identifies the gaps in the cross-sector legislation on environmental impact assessment, and the deficiencies of sector-specific legislation on environmental impact assessment, which have privileged quantitative criteria associated to the size of the project, over qualitative criteria associated to the real impact of the amendment of the project.

I should not think it necessary before this audience to dwell at length upon the biological reality of the population. Just as the morphologist and physiologist concern themselves with the cell and organism as structural and functional units, so, it seems to me, the ecologist centers his attention around the population. There is nothing esoteric or paradoxical in this viewpoint. Certain resemblances between cell, organism and population emphasize the common properties of these three entities, while, at the same time, the possession by the population of other characteristics stresses its biological uniqueness. lt is these characteristics that give the population its individuality and make it so important from the point of view of the modern biologist; sufficiently so, apart from other possible considerations, to justify the existence of ecology.


In open-pit mines and quarries, mining of ore beneath overlying burden is mostly performed by the help of appropriate blasting processes in easing of the excavation of adjacent rock. Reaching to required blast outcomes is expected to effect the succeeding processes, directly. Therefore an easy control and site specific blast program is necessary, most of the time. In this study, first by, many effective factors on blast design were investigated, secondly, the related theoretical and/or practical equations up-to-date which include these factors were studied. A user-driven computer model was developed using Pascal Software Language to be able to fulfill design considerations of the blast area interacting with the input-data keyed in. To begin with, the developed computer model was put into test running it under several predetermined values of different blast design considerations. Later, it was run several times using mechanical characteristics of rocks sampled from a private limestone quarry and recommendations were suggested on blast design.


THISIS A BIBLIOGRAPHIC ESSAY on the administrative and pedagogical issues related to the establishment and operation of an instruction program. The authors assume that such a program is an essential part of any academic library which fully supports an academic program. We also assume that the library administration and staff are committed to bibliographic instruction. This review of the literature will describe the state of the art and also indicate some unresolved problems and unanswered questions. This review began with such basic works as Lubans, Scrivener, and Givens,' and concentrated attention on publications from 1973 to June 1979. Two recent committee reports are most important to this paper and will be cited frequently. The Bibliographic Instruction Handbook (1979), written by a committee of the Association of College and Research Libraries (ACRL), outlines what academic librarians should consider in implementing a program: objectives, organization, staffing, instructional materials and methods.* The other key publication, edited by Manning in Australia, is prescriptive in tone and specifies objectives, staffing, organization, facilities, and equipment for a typical program.3 A 1978 book by Fjallbrant and Stevenson is a useful, but somewhat simplified, how-to manual for beginner^.^


Diffusion brazing was performed between titanium (Grade 2) and stainless steel (X5CrNi18-10) using as a filler a nickel foil at the temperatures of 850, 900, 950 and 1000°C. The microstructure was investigated using light microscopy and scanning electron microscopy equipped with an energy dispersive X-ray system (EDS). The structure of the joints on the titanium side was composed of the eutectoid mixture αTi+Ti2Ni and layers of intermetallic phases Ti2Ni, TiNi and TiNi3. The stainless steel-nickel interface is free from any reaction layer at 850°C, above this temperature thin layer of reaction appears. The microhardness measured across the joints reaches higher values than for titanium and stainless steel, and it achieves value from 260 to 446 HV. The highest shear strength (214 MPa) was achieved for joints brazed at 900°C.


Background This retrospective study aimed to investigate whether a three-dimensional (3D) model would improve the achievement of TRIFECTA, which was defined as the absence of perioperative complications and positive surgical margins and a warm ischemia time of <25 minutes, during robot-assisted partial nephrectomy (RAPN). Methods Prior to RAPN, a 3D-square type kidney model was prepared and used for all RAPN procedures in patients with T1a renal cell carcinoma (RCC) treated at a single center between March 2016 and April 2019. All RAPN procedures were performed by a single surgeon. Results The study included 50 patients, of whom 22, 24, and 4 had low-, intermediate-, and high-risk R.E.N.A.L Nephrometry scores, respectively. The TRIFECTA achievement rate was 86.0%, and transfusion or conversion to radical nephrectomy was not required in any of the patients. Only one Clavien-Dindo grade 3 complication was reported—a pseudoaneurysm that required embolism. The TRIFECTA achievement rate was independent of the R.E.N.A.L Nephrometry scores and the surgeon's experience level (25 cases each of early and advanced experience). Conclusions The 3D model contributed to the achievement of TRIFECTA during RAPN performed by a less-experienced surgeon. These findings should be further evaluated in studies involving a larger number of cases and surgeons.


Burma and Japan had long held the strongest ties among Asian countries. Such "historically friendly relationship" were based also on the sentiments and experiences of the leaders of both countries. Young Burmese patriots were trained by the Japanese army officers leading to the birth of the Burma Independence Army. Huge official development assistance provided by the Japanese government also cemented this "special relations". However the military coup (1988) and Japanese ODA Charter (1992) drastically changed this favorable ties. Japan's government and business have shown a keen interest in Myanmar since the establishment of a formally civilian government (2011) and beginning the rapid political reforms.


Based on the monitoring effect of creditors, this paper examines the relevance between group's internal capital market and cash holdings. We find that the groups have become the economic pillar organization in China, but groups' internal capital markets generally exist the inefficient phenomena. We further find that the group's members on average have more cash holdings than independent companies and the moderating effect of bank debt's intervention can strengthen the negative relevance between internal capital market and cash holdings. Our findings suggest that groups should follow the pace of economic reform to enhance efficiency of internal capital market and reduce cash holdings by the way of appropriate bank debt.


The representation of boat motifs on painting, seals, hero stones (memorial stones), caves and coins have been reported from the Indian subcontinent dating from the prehistoric period to modern times (Mookerji, 1912; Chandra, 1977). The Indus civilization, one of the oldest among the major civilizations of the Bronze Age has several depictions of boats on pottery, seals and terracotta models (Konishi, 1985). The Archaeological Museum at Old Goa houses two hero stones (Tripati, 2006). One of them depicts a naval battle, depicting two boats overlapping and men fighting with bows and arrows. The second portrays a ship being transported on a wheeled carriage for launching, indicating a greater organization of seafaring activities in the past (Rao, 1988).


Energetic losses in systems especially miniaturized systems are presently a global challenge. In this work, four new models were developed through a combination of bond orbital model, Tomlinson's model and Sang's equation. Using Jump energy models, ∆ which is the energy that prevents the tips jump was calculated for Silicon (Si), Zinc Sulphide (ZnS) and Cadmium Sulphide (CdS). Through a combination of Tomlinson model and Sang's equation, temperature model was developed. This model was modified to obtain normal load model. This final model was used to investigate the effects of normal load on nanotribology of silicon. The results obtained compare favourably with experimental results for Si found in literature. Hence the model was used for zinc sulphide and cadinium sulphide. The results show that friction at nanolevel increases with increase in normal load. There are no experimental results for zinc sulphide and cadmium sulphide. Hence, we are predicting experimental results for these semiconductors for the first time using our models.

This study was conducted to evaluate the performance of two small‐scale irrigation (SSI) schemes in the subhumid Ethiopian highlands. Water application at the farm level and flow velocity along the main canal were monitored using a Parshall flume and current meter, respectively. The infiltration was measured at the head, middle and tail of the scheme within the command area using a double‐ring infiltrometer. Soil samples were collected using an auger up to 60 cm in depth. Climatic and agronomic data were supplied to the crop water assessment tool (CROPWAT) to determine crop water requirements. The results showed that the average conveyance efficiency for the lined main canal was 90% and 92% for the Mugie and Fesas SSI schemes, respectively. The conveyance efficiency for the unlined main canal was in the order of 86% and 87% for the Mugie and Fesas SSI schemes, respectively. On the other hand, the average application efficiency and overall efficiency were found to be 56% and 51%, respectively, with a storage efficiency of 50% for the Mugie irrigation scheme. Similarly, the overall, application and storage efficiencies were 50%, 54% and 56%, respectively, for the Fesas irrigation scheme. Failure of operating gates, canal siltation and leakage through the main canals were the main causes of poor performance.


Sugarcane bagasse (SCB), an abundant agro-industrial residue in Vietnam, was used as a raw material
to produce cellulose nanofibrils (CNF). First, SCB pulp was obtained from the raw material of bagasse
using a two-fraction method, soda treatment followed by bleaching with Javel solution. Then, the
SCB pulp was converted into nano-sized cellulose fibers by subjected to low energy, economical
treatment of TEMPO-mediated oxidation. A traditional mechanical method of fibrillation SCB pulp,
stone grinding was done for comparison, the produced nanocellulose is referred to as MeSCB. The
nanocellulose fibers refer as TOSCB obtained from the TEMPO oxidation process were characterized
in terms of carboxyl content, morphology, crystallinity and thermal stability. The degree of fibrillation
and the dimension of the two obtained nanocelluloses was determined by applying FE-SEM
observations combined with an image processing application, ImageJ. The results show that the MeSCB
were much less nanofibrillated than the corresponding TOSCB material but less toxic.

 And KβX-ray emission spectra of V (metal), [V(pd)3](pd = pentane-2,4-dionate), VF3, VO2, V2O5, [VO][SO4], [NH4][VO3], and [NH4][V3O8] are reported. It is argued that peaks of higher energy than Kβ1,3 are due to transitions involving molecular orbitals with Vp character rather than V 3d. The relative intensities and emission energies of the Kβ1,3, Kβ″, and Kβ2,5 peaks are discussed using m.o. theory. The Kβ″ : Kβ2,5 relative intensity is much higher than for comparable main-group compounds; this is probably due to the presence of 3p character in the orbital that gives rise to Kβ″; 3p character also enhances the intensity of Kβ2,5. Changes in peak positions and relative intensities associated with the oxidation state of vanadium can be qualitatively rationalised by a consideration of 4p character alone. It is suggested that the Kβ‴ peak observed at higher energies (+15 eV) than Kβ2,5 is formed by relaxation of an electronically excited species (resonance radiation).


Abstract As pressures on ocean fisheries have grown, pervasive evidence of over‐exploited resources and economic distress has revealed fundamental weaknesses in traditional regulatory policies. In their search for new management approaches, fishing nations have recently turned their attention to the nature of fishing rights, and the trend is clearly toward more well‐defined, exclusive property rights. In a remarkably short time the tradition of open access to ocean fisheries has waned; rights to most of the world's fish resources have been appropriated by coastal states, their governments have excluded everyone from access to the stocks except those who hold licenses, and increasingly, the rights of license holders are quantitatively specified. Experience so far suggests that strengthening the property rights of fishing enterprises is a promising means of improving the management of marine resources as well as the economic performance of fishing industries, and it portends profound changes in fishing regimes.


The present invention relates to a compound loudspeaker. In the loudspeaker, the L.F. drive unit has a curved flexible diaphragm whose shape is determined such that it optimally controls the directivity of the compound loudspeaker to produce matched directivity of the L.F. and H.F. drive units. The L.F. diaphragm drive unit radiates sound by the controlled flexure of its diaphragm and thus, eliminates the need for a flexible rolling seal at the edge of the diaphragm. This allows for a continuous smooth surface to exist between the H.F. drive unit and the exterior of the loudspeaker, thereby greatly improving its radiation characteristics.


In the small-plot experiment of the Russian State Agrarian University - Moscow Timiryazev Agricultural Academy against potato viruses in 2014-2019 were tested some kinds of preparations with antiviral activity: Pharmayod, GS (100 g/l of iodine); Immunocytophyte, TAB (20 g/kg arachidonic acid ethyl ester); Ecogel, WS (30 g/l of chitosan lactate); Amulet, TAB (composition of linear polyaminosaccharides (chitosan) in succinic acid solution); Zerox, WS (3000 mg /l colloidal silver); Viron, WS (biostimulant based on urea and citric acid with the addition of essential oils). According to the results of the studies, it was found that, in addition to the effect on the causative agents of viral diseases of potatoes, all tested preparations had a stable tendency to maintain or increase the yield of tubers of infected plants. The increase in the yield of tubers ranged from 0.5 to 1.3 kg/m2. In 2016 under the production conditions of Astrakhan region on the potato variety Impala infected with the PVM + PVS and PVM + PVS + PVY virus complexes a comparative assessment of the effect of Pharmayod and Immunocytophyte revealed a significant increase in the gross and marketable yield of potato plants in the areas with the use of these preparations compared to with control.


An in situ NMR technique is used to measure the relative monomer consumption rates of acrylamide (AM) and acrylic acid (AA) over a broad range of initial comonomer compositions, initial monomer concentrations (5–40 wt % in aqueous solution), and the complete range of AA ionization. The composition drift with conversion was found not only to be a strong function of AA ionization but also to vary systematically with monomer concentration, with the latter influence increasing at increased degrees of ionization. The coupled effect is captured by expressions developed to represent the monomer reactivity ratios as a function of these two major variables. The proposed correlation, easily implemented into any modeling framework, is based on experimentally measured composition over a much broader range of conditions than examined in previous studies and accurately captures the effect of monomer concentration at low and high degrees of ionization.


Given modern society's dependence on technological infrastructure vulnerable to cyber-attacks, the need to expedite cybersecurity adoption is paramount. Cybersecurity advocates are a subset of security professionals who promote, educate about, and motivate adoption of security best practices and technologies as a major component of their jobs. Successfully recruiting and retaining advocates is of utmost importance. Accomplishing this requires an understanding of advocates' motivations and incentives and how these may differ from other cybersecurity professionals. As the first study of its kind, we interviewed 28 cybersecurity advocates to learn about their work motivations. Findings revealed several drivers for cybersecurity advocacy work, most of which were intrinsic motivators. Motivations included interest in the field, sense of duty, self-efficacy, evidence of impact, comradery, and, to a lesser degree, awards and monetary compensation. We leverage these insights for recommendations on how to frame cybersecurity advocacy as a profession that fuels these motivations and how to maintain this across advocates' careers.


The Human Figure Drawings is one of the most divulged and used instruments in the practice of psychological evaluation of children in Brazil. Recently, Wechsler (2000, 2003) published a new correction system to cognitive evaluation. This work constitutes the first attempt of psychometric analysis of items related to male figure using mathematic models from Item Response Theory (IRT). The analysis of the results obtained in two samples of children (711 from the city of Campo Grande and 564 from the city of Belo Horizonte) with the Male Drawing points that the internal consistency of the instrument is adequate (.87) when 53 items are considered. Nevertheless, the IRT analysis, polytomous item responses, shows problems of difficulty and discrimination of a group of items. It's inferred that the instrument is not well calibrated and consequently there is a necessity of adjustments on the set of items that compound it.


Abstract : Myelodysplastic syndromes (MDS) are acquired bone marrow failure disorders characterized by poor clinical outcomes due to progressively worsening blood cell counts (especially red blood cells) and increased risk of developing leukemia. MDS originates in hematopoietic stem cells (HSC), but there is little information available regarding the molecular mechanisms regulating MDS HSC function. We have characterized the expression of more than 750 microRNAs in MDS HSC purified from MDS patient samples and compared their expression to normal, age-matched controls. These studies identify at least 31 microRNAs that are differentially expressed in MDS HSC compared to normal controls (FDR 0.1, P0.05). We have initiated studies to characterize the potential role of these microRNAs in MDS pathogenesis by using a combination of in vitro assays and a newly developed xenograft model of MDS. Our findings are consistent with a role of miRNA s in MDS HSC function and future studies will aim to validate the role of each of these candidate miRNAs in MDS development and progression.


The technology of service-oriented architecture (SOA) and Web service provides a promising method to rapidly develop the distributed interoperable system for E-commerce applications at low cost. Due to the cross-organizational feature, the dynamic replacement of service process is an important way to guarantee the correctness of service software evolution, supporting the capacity of handling unexpected service failures. However, considering the new services used in the reconfigured process may be incompatible, data consistency should be checked to ensure that the original business logics can be accurately simulated. In response to this problem, we propose an approach to data consistency checking for the dynamic replacement of service process. First, the behavioral model and data model for formalizing service process are introduced, and then the data consistency problem of dynamic replacement is discussed. Second, the data replacement patterns are presented to specify different kinds of replacement behaviors. Third, the single-service replacement method is used to check the data consistency of an individual service dynamic replacement, which aims to compute the similarity degree between interface data. The multi-services replacement method is employed to check the data consistency of a set of services dynamic replacements, which explores critical paths to substitute a part of service processes. Finally, a case study and experiments demonstrate the effectiveness and efficiency of the proposed methods in the data consistency of dynamic replacement. Our approach provides fundamental theory guidance to enhance the credibility of service process in the modern service industry.


Multidimensional data summarization is a fundamental mechanism to accelerate the computation of machine learning (ML) models. On the other hand, relational DBMSs can scale beyond main memory limits, they can evaluate SQL queries in parallel and they hide complex internal system details. Heeding this motivation, we present a wide spectrum of alternative SQL queries to compute a summarization matrix that significantly accelerates the computation of many ML models in a data science language (e.g. Python). We consider two fundamental storage layouts: horizontal and vertical. Our proposed SQL queries lead to diverse query plans, which in turn yield highly different processing times. We identify storage layout (row vs column) and relational join optimization as two key performance factors. After careful analysis and bechmarking, we recommend two SQL queries that can work across DBMSs. We show UDFs, an extensibility mechanism, despite being faster, they have many disadvantages compared to plain SQL queries (not portable, system-dependent limitations, main memory, manual optimization required). An extensive experimental evaluation shows the pros and cons of our proposed SQL-based solution. Columnar storage provides an order of magnitude performance improvement over row storage. Moreover, SQL queries can match UDF performance on sparse matrices. We show that by exploiting the summarization matrix in Python, the computation of two popular statistical models (Linear Regression and PCA), is much faster than popular Python libraries (on a single machine) and also faster than Apache Spark (in parallel, in-memory solution for big data clusters). We also show our SQL-based solution exhibits linear speedup in parallel processing. In short, the DBMS can act as a backend linear algebra kernel.


Graphite electrode modified with functionalized graphene (FG) is a new family of electrocatalysts for the oxidation of nicotinamide adenine dinucleotide (NADH). A substantial decrease in the over potential of NADH oxidation is observed on functionalized graphene modified graphite electrode (FGGE). The COO− functionalized graphene is characterized by powder X-ray diffraction and infrared spectroscopy techniques and the modified FGGE is characterized using cyclic voltammetry (CV), electrochemical impedance spectroscopy and scanning electron microscopy. The modified electrode is found to be stable and reproducible. The FGGE shows rapid and highly sensitive amperometric response to NADH.

GAEvac is an evacuation computer model on the basis of geometric method and intellectualized aim distinguishing. This model can express the space of buildings and the body of evacuees through some simple geometry elements; it can also simulate the velocity change of evacuees through collision detection and position adjustment algorithms. By setting target classification and condition decision rules, the choice of evacuation route can be simulated and the group effects can be reflected. To analyze the accuracy of GAEvac, two experiments with different velocity changes and route choices were simulated and the results were compared. Finally, an illustration was made, which shows that this model is of practicability and referring value.
