Under the action of an electric field and in the presence of water, water trees develop inside power cables insulations. Regardless of their type, shape or dimension, water trees contribute to the worsening of electrical properties, especially lowering the inception voltages of partial discharges and electrical trees leading to breakdown [1]. In this paper an experimental study regarding the variation of permittivity and loss factor of the polyethylene with the frequency (f<inf>a</inf>) and the duration (τ) of applied electrical field is presented. The experiments were made on flat XLPE samples sliced from a power cables insulation. The samples were subjected to an electrical field with the intensity E = 4 kV/mm and frequencies f<inf>a</inf> = 3 and 5 kHz for τ = 48, 72 and 96 hours. After ageing the water trees dimensions (length l<inf>wt</inf> and diameter D) and concentration c<inf>wt</inf> were measured. The permittivity (ε<inf>r</inf>) and the loss factor (tgδ) were measured (using a NOVOCONTROL dielectric spectrometer) at the temperature T = 30 °C and frequency f<inf>m</inf> = 103−–106 Hz. The results show that with the increase of ageing time or the ageing frequency all the quantities c<inf>wt</inf> l<inf>wt</inf> D, ε<inf>r</inf> and tgδ increase, too.


The article describes planning the road network as a very real present day problem, which will continue and become even more acute in the future. Roads are not adequately treated scientifically, nor are those responsible for roads employed efficiently. There is a lack of necessary co-ordination of all those engaged in land use planning, which results in difficulties for its completion and putting it into practice. /TRRL/


The magnetic properties of several amorphous alloys prepared by melt spinning have been studied. These comprise alloys of the series Tb1−xCox, Y1−xCox (0.25⩽x⩽0.60), and R69Co31 (R=La, Nd, Sm, Gd, Tb, Dy, Ho, and Er). Most of the alloys in which the R component has an orbital momentum were found to exhibit large intrinsic coercive forces at low temperatures. The thermomagnetic history effects studied on several of these alloys have been interpreted in terms of a thermally activated magnetization process. The magnetic ordering temperatures of the series R69Co31 scale to the deGennes factor (g−1)2J(J+1) only approximatley. The systematic deviations suggest that the indirect magnetic coupling between the localized 4 f moments involves a term proportional to Si⋅Lj in addition to the main term, proportional to Si⋅Sj .


Developing sensor ontologies and using them to annotate the sensor data is a feasible way to address the data heterogeneity issue on Internet of Things (IoT). However, the heterogeneity issue exists between different sensor ontologies hampers their communications. Sensor ontology matching aims at finding all the heterogeneous entities in two ontologies, which is a feasible solution for aggregating heterogeneous sensor ontologies. This work investigates swarm intelligence (SI)-based sensor ontology matching techniques and further proposes a competitive binary particle swarm optimization algorithm (CBPSO)-based sensor ontology matching technique. In particular, a guiding matrix (GM) is proposed to ensure the population's diversity and a competitive evolutionary framework is presented. The experiment uses ontology alignment evaluation initiative (OAEI)'s benchmark and three real sensor ontologies to test CBPSO's performance. The experimental results show that the competitive evolutionary framework is able to help CBPSO effectively optimize the alignment's quality, and it significantly outperforms other SIs at 5% significant level.


According to the Doppler Effect between moving acoustic source and receiver, an approach is proposed for identification of tone noise sources on underwater moving object with single hydrophone. Firstly, the product high-order ambiguity function (PHAF) is used to estimate the instantaneous phase and amplitude of the received Doppler signal. Then the abeam moments when tone noise sources have the closest approach to the measuring hydrophone are estimated by nonlinear weighted least-squares algorithm. Locations of tone noise sources are obtained by referring to a known acoustic source fixed on the moving object at last. The experiment results showed the validity of the proposed method.

The existence of microcracks in solder interconnects plays a key role in determining the performance and reliability of solder interconnects, in particular, may increase significantly the potential for brittle interfacial fracture of interconnects and reduce the thermal conductivity of the systems. Thus, characterization of the formation and propagation of microcracks is very important for evaluating the performance and reliability of solder interconnects. In this paper, a phase field crystal model is utilized to study the morphological evolution and propagation of microcracks in a typical solder joint consisting of the Sn-based solder and Cu substrate. The simulation results show that the initial crack notch configuration affects sigificantly the crack propagation. The length and area fraction of the crack gradually increase with the simulation time, while the crack propagation rate decreases initially and then becomes stabilized with the simulation time. The atomic density in the initial crack notch can also affect the crack propagation. The number and size of the crack branches increase with increasing both the atomic density in the initial crack notch and simulation time. When the atomic density in the initial crack notch is 0.9, new cracks form around the pre-existing cracks, and the propagation velocities of cracks along the x and y directions are the same. When the atomic density in the initial crack notch is 0.6, the cracks propagate faster along the y direction than the x direction.


Summary Concentrations of oxalate and calcium in soluble or structural forms, as calcium oxalate in the pericarp, or as oxalate in the fruit pedicel, and the distribution of calcium in the pericarp and fruit pedicel were studied in litchi (Litchi chinensis Sonn.) using cracking-resistant cv. 'Huaizhi' and cracking-susceptible cv. 'Nuomici'. Oxalate in the pericarp existed mainly in a soluble form and was significantly (P < 0.05) higher in 'Huaizhi' than in 'Nuomici'. The concentration of oxalate was higher than the amount of calcium oxalate. Calcium was first mobilised for the construction of cell walls in the pericarp, despite the high concentration of oxalate in the tissue. 'Huaizhi' fruit accumulated more structural calcium and calcium oxalate in the pericarp than 'Nuomici' fruit. There was no difference in soluble calcium between the two cultivars. Calcium oxalate was located chiefly in the epidermis of the pericarp, and increased in concentration within 50 d after anthesis (DAA) in 'Nuomici' and 64 DAA in 'Huaizhi', then decreased as structural calcium increased, indicating that calcium sequestered by oxalate could be remobilised.The fruit pedicel had higher concentrations of oxalate than the pericarp. X-ray microanalysis showed abundant calcium in pedicel tissue adjoining the fruit base, and less calcium in tissues at the fruit base and in pedicel tissue 1 cm from the fruit, suggesting that the pedicel serves as a bottleneck to calcium movement. This bottleneck is not likely to be caused by oxalate in the pedicel. Oxalate in the pericarp and in the fruit pedicel is not linked to a shortage of fruit calcium or to an increase in cracking incidence in litchi.


The chaperone-usher pathway of adhesive structures biogenesis is highly conserved in all Gram-negative bacteria. Pili are polymers of thousands protein subunits that possess conserved immunoglobuline-like structure denoted by lack of the seventh G strand. The effect of this structural defect is a hydrophobic acceptor cleft. The folding of protein subunits is strictly dependent on the action of specific periplasmic chaperone protein that complements the defective structure of a subunit by donating a specific donor strand. Stable chaperone-subunit complex migrates to the usher protein located in the outer membrane, where the process of protein subunits polymerization occurs. The crucial role in this mechanism is performed by chaperone the structure of which is highly conserved.The structural and functional conservation of this mechanism renders it a good potential target for development of a new class of antibacterial agents. Pilicides originally proposed by Svensson et al. in 2001 are a derivatives of a dihydrothiazolo ring-fused 2-pyridone scaffold that block formation of the adhesive organelles by impairing with the step of interaction between chaperone-subunit complex and usher protein. The anti-bacterial activity of pilicides as specific blockers of the chaperone-usher pathway has been confirmed only in the case of E. coli producing type 1 and P pili that represent the FGS type organelles. In our works we addressed a crucial question denoting spectrum of the anti-bacterial activity of pilicides: Are pilicides the potential anti-bacterial agents that target bacterial virulence in all pathogenic Gram-negative bacteria encoding chaperone-usher organelles of both FGL and FGS type? As a model of the FGL adhesive structures we used the uropathogenic E. coli strains producing Dr fimbriae. Biological evaluation based on the whole-cell assays showed that the E. coli Dr+ cultivated in the presence of pilicides possessed the amount of Dr fimbriae reduced to 85 %. This results in the high inhibition of bacteria adherence propensity to human cells. To prove that the observed inhibition of Dr fimbriae assembly is a consequence of pilicide impairing with the chaperone-usher pathway we measured the relative affinity of pilicides to the DraB protein using the surface plasmon resonance technique. Based on the conservation of the FGL type assembly machinery we conclude that the pilicides should be effective inhibitors of adhesive organelles biogenesis of this type.


A novel lanosterol-derived metabolite, penasterol (1), with potent antileukemic activity has been isolated from the Okinawan marine sponge Penares sp. and the structure elucidated on the basis of evidence provided by spectroscopy and chemical transformations. This is the first isolation of a marine sterol with a 14-carboxy group potentially important within the framework of sterol biosynthesis.

If piezoceramics are excited by weak electric fields a nonlinear behavior can be observed, if the excitation frequency is close to a resonance frequency of the system. To derive a theoretical model nonlinear constitutive equations are used, to describe the longitudinal oscillations of a slender piezoceramic rod near the first resonance frequency. Hamilton's principle is used to receive a variational principle for the piezoelectric rod. Introducing a Rayleigh Ritz ansatz with the eigenfunctions of the linearized system to approximate the exact solution leads to nonlinear ordinary differential equations. These equations are approximated with the method of harmonic balance. Finally it is possible to calculate the amplitudes of the displacements numerically. As a result it is shown, that the Duffing type nonlinearities found in measurements can be described with this model.


In this work will be discussed the problematic of the UAV navigation for the remote management in vision of a BLOS capability showing the research experience developed in collaboration with Alenia Aermacchi, focusing on the solution adopted for increasing the navigation automations and the system interoperability. The first section presents an overview of such problems and the guideline followed to provide a relevant solution. The second section exhibits the effective implementation of the studied cases on the Alenia Aermacchi Sky-Y UAV focusing on the navigation issues. During the navigation functions development a large use of simulators occurred: one Matlab® model and one Simulink® simulator have been developed for this purpose, then the proper Alenia Aermacchi Sky-Y flight simulator has been used before the RIG tests. In the last part of this work some results of such simulations are presented by showing some significant cases of navigation test done with the different tools mentioned above


In "How Is Testing Supposed to Improve Schooling," Haertel describes seven broad mechanisms whereby testing is used to improve schooling (this issue). The first four are direct mechanisms, meaning that "test scores are taken as indicators of some underlying construct and on that basis scores are used to guide some decision or draw some implication." The last three are indirect mechanisms, which are "intended, anticipated effects of testing that have no direct dependence on the information particular scores provide about underlying constructs." The indirect mechanisms are poorly understood and need more attention from measurement professionals. He outlines the challenges to studying indirect mechanisms and how those challenges might be addressed. In this commentary, I would like to offer one more challenge: the attitudes and beliefs of the public toward tests and test scores, attitudes and beliefs that can stem from an inability to deal with numbers as documented in Joel Best's Damned Lies and Statistics. In Damned Lies and Statistics, what Best describes as the most common ways of mishandling statistics sound very similar to ways of mishandling test scores: "making inappropriate generalizations from a statistic," "taking a number that means one thing and interpreting it to mean something completely different," and "misunderstanding the meaning of more complicated statistics" (p. 65). He describes some especially striking examples of how statistics can be misunderstood, perverted, or misused. For example, he begins with a statement that appeared in a journal article: "Every year since 1950, the number of American children gunned down has doubled" (p. 1). He points out that if this were true, the number of American children gunned down would have surpassed the world population in 1987, and he then traces the history of the statement and describes how the statistic mutated from a more reasonable statement. Best describes three unfortunate consumers of statistics: those who adamantly disregard all numbers; those who uncritically accept all numbers; and those who manipulate the numbers to their advantage. I propose to use the same categories to describe consumers of tests, as outlined below.

—It is noteworthy that the definition of system robustness varies according to the context in which the system is used. Therefore, manifold meanings of system robustness were introduced in literature. Additionally, various formal measures and metrics were presented to achieve the system robustness. In previous papers, we proposed a new concept to keep a multi-agent system robust when deviations from planned (desired) behaviour occur in the system. This concept introduces a robust hybrid central/self-organising multi-agent system. The scenario used in this work is a traffic intersection without traffic lights. In this paper, we extend our prototype implementation with the aim of making it capable of handling disturbances (accidents) occur in the system environment (intersection) aiming to completely realise our vision. Simultaneously, we develop an appropriate metric for the quantitative determination of the robustness.


The large number of the workforce is unemployed because apart from the lack of employment, there is also a lack of taking advantage of opportunities and a lack of skills. These conditions make them look for alternatives to get income in accordance with the capital they have. Therefore, they decided to become street vendors. The purpose of this research is to find out the problems faced by street vendors and the solutions to these problems in order to encourage the improvement of the merchant's economy and people's welfare. In addition, this study aims to determine social capital that influences the existence of street vendors. This study uses a qualitative method with an ethnographic approach. The results obtained in this study are the need for empowering traders by the government in order to support and enhance sustainable economic development.


Automatic emotion recognition from Speech (AERS) systems based on acoustical analysis reveal that some emotional classes persist with ambiguity. This study employed an alternative method aimed at providing deep understanding into the amplitude–frequency, impacts of various emotions in order to aid in the advancement of near term, more effectively in classifying AER approaches. The study was undertaken by converting narrow 20 ms frames of speech into RGB or grey-scale spectrogram images. The features have been used to fine-tune a feature selection system that had previously been trained to recognise emotions. Two different Linear and Mel spectral scales are used to demonstrate a spectrogram. An inductive approach for in sighting the amplitude and frequency features of various emotional classes. We propose a two-channel profound combination of deep fusion network model for the efficient categorization of images. Linear and Mel- spectrogram is acquired from Speech-signal, which is prepared in the recurrence area to input Deep Neural Network. The proposed model Alex-Net with five convolutional layers and two fully connected layers acquire most vital features form spectrogram images plotted on the amplitude-frequency scale. The state-of-the-art is compared with benchmark dataset (EMO-DB). RGB and saliency images are fed to pre-trained Alex-Net tested both EMO-DB and Telugu dataset with an accuracy of 72.18% and fused image features less computations reaching to an accuracy 75.12%. The proposed model show that Transfer learning predict efficiently than Fine-tune network. When tested on Emo-DB dataset, the propȯsed system adequately learns discriminant features from speech spectrȯgrams and outperforms many stȧte-of-the-art techniques.


Methods have been presented for alum-precipitation of the protective antigen of Bacillus anthracis. The product induced effective immunity in rabbits, guinea pigs, and monkeys. Significant immunity persisted for more than three months in rabbits and for more than 14 months in monkeys. Immunity in monkeys was effective against both intracutaneous and respiratory challenge. Alum-precipitated antigen deteriorated slowly when stored at 4°C, but considerable potency remained after storage for approximately two years. The product was devoid of toxicity when tested in mice, guinea pigs, rabbits, and monkeys. Injection of the antigen into man was well tolerated; no serious reactions were encountered and moderate local reactions were infrequent.


Summary form only given. Details of the electropolymerization process of biphenyl on platinum electrode were studied. It is shown that the presence of water in the solution has a strong effect on the formation of polyphenylene. The influence of biphenyl concentration, solvent, rotating speed of the electrode and the upper limit of the electrode potential on the growth rate and the redox behavior of the polymer was also studied. The relationship between the redox charge of the deposited polymer (Q) and the potential cycling parameters has the simple form Q = a(n/v)exp(bE/sub s/) (a and b are constants; n is the potential cycle number, v is the potential scan rate and Es is the upper limit of applied potential).


The present invention starts from the vehicle brake system hydraulic with a device for the service brake and wheel slip control of the human power (10). According to the present invention, a self-priming pump is used in conjunction with an accumulator (30) which is uniquely formed in the case of this type of vehicle brake system. Accumulator (30) is separated elements have a (66; 120; 100, 110), these separation elements (66; 100, 110; 120) a first accumulator chamber, respectively (76) a second accumulator to separate from the chamber (74). Inflow passage (44) leads to the first accumulator chamber (76), outlet channel separated from the inlet passage (44) (46) departs. Separating element (66; 100, 110; 120) have been arranged in freely movable between two end positions, separating element inlet channel at one end position (66; 100, 110 120) (44) blocking the pressure medium coupling between the outflow channel (46) and.


IP traceback is useful in detecting and defending against Denial-of-service (DoS) attacks. Packet marking has been studied as a promising approach to realize IP traceback. An IP traceback system that is deployed at the level of Autonomous Systems (AS) to deal with these attacks is proposed in this study. Our system distinguishes itself by not requiring the knowledge of network topology, while tracing back a single packet, when compared with other IP traceback systems. The Autonomous System Border Router (ASBR) of each AS would mark the packets with the AS Number (ASN) that cross the router. The marked packets are then used to reconstruct the attack path involving the ASes. To facilitate reconstruction, we log the previous ASN in AS Traceback Server (ASTS) of each AS. To reduce the storage overhead, we partially implement the system. We evaluate and provide the performance of our system under partial deployment scenario.


Reducing the use of seclusion to deal with challenging behaviour is a priority in secure services for women. This study describes the concurrent introduction of a series of initiatives based on recovery principles and the full involvement of patients in their risk management plans. Following change implementation, the first 19 patients who had completed one year of treatment were matched with 19 patients who had completed their first year of treatment before change. A significant decline in both the number of seclusions and risk behaviour post-change was complemented by improved staff ratings of institutional behaviour, increased treatment engagement and a reduction in time spent in medium security. Staff and patients differed in terms of their ratings of the most effective strategies introduced. Patients favoured the Relational Security item of increased individual engagement and timetabled Behaviour Chain Analysis sessions. Staff viewed on ward training and use of de-escalation techniques as most effective. Findings confirm results from mixed gender forensic mental health samples that seclusion can be successfully reduced without an increase in patient violence or alternative coercive strategies. Limitations of the study are discussed along with the need for future evaluations to address issues of fidelity and utilise vigorously designed case studies.


While changes in temperature and precipitation will likely affect debris flows, developing relevant future climate projections remains challenging. Three of these challenges are considered in this work: linking past debris flows with the meteorological trigger, how to approach the necessary downscaling of global climate projections, and finally, dealing with uncertainty. To illustrate each of the three challenges, examples are taken from two European alpine catchments: Barcelonnette in the French Alps, and Fella River in NE Italy.


Polymethyl methacrylate (PMMA) is one of the materials used for the temporary crown while making fixed partial dentures. Unfortunately, it has low mechanical properties. This study aim's to improve PMMA hardness by adding ZrO2-Al2O3-SiO2 filler system in two different calcination temperatures. Thirty-two disc form samples with 8mm diameter x 3mm thickness were made from two category-filler based that had been previously evaluated using Scanning Electron Microscope (SEM). Each category was divided into six groups of three respectively from a controlled and different concentrations of 7(A), 9(B), 11(C), 13(D), and 15(E) weight % of reinforced filler system, then tested with Vickers Hardness Tester. Filler particles that calcined at 550° can increase to 700° consist of fine crystalline and amorphous phases; however, the sample shows the highest hardness about 20,19 VHN even though the increase is only 7,5% compared to control. Meanwhile, the sample that calcined at 700°C exhibiting the highest hardness about 15,66 VHN corresponds to sample D, it has increased 25% compared to the control. This is correlated with microstructure result that has more growth crystalline particles. The results were analyzed by ANOVA which determined were not statistically significantly different (p<0.05). Therefore, it can be concluded that the 13% reinforced ZrO2-Al2O3-SiO2 filler system calcined at 700°C shows the highest hardness increase compare to calcination temperature 550-700°C. Although it is not significantly different.


Diabetes is a disease that can cause serious late complications. Among them diabetic foot syndrome is one of the most dangerous because can lead to foot amputation. It is very important to assure good medical care for diabetic patients not only during the stay at the hospital but also at home. Telecare can be good solution for extending medical care to patients' homes. The developed TeleDiaFoS system is able to transmit the pictures of feet as well as the measurement data from patient's home to the clinic where physicians can analyze data and change the way of the patient's treatment. A newer version of TeleDiaFoS system has been developed in the project of Model Center for Diabetic Treatment. The telecare gives an advantage in comparison to the traditional medical care both for patients and physicians because changes in patient's state are immediately transferred to medical staff.


In the present work an attempt has been made to design the antibiotic drug loaded carbopol-poly(NVP) based hydrogel wound dressings for better wound care. The polymer films were characterized by SEM-EDX, AFM, FTIR, 13CNMR, TGA/DTA/DTG, DSC, and swelling studies. Besides drug release, various biomedical properties (viz. blood compatibility, mucoadhesion, oxygen permeability, water vapour transmission rate, microbial penetration, tensile strength, bursting strength, resilience, stress relaxation, and folding endurance) have also been studied. The polymer films have been observed to be biocompatible, permeable to oxygen and water vapour and have absorbed simulated wound fluid 11.37±0.31 g/g of polymer film.The drug release profile followed the Case-II diffusion mechanism and release profile best fitted in Hixson-Crowell's kinetic models.Mechanical properties results showed that the polymer film had 0.65±0.12 Nmm-2 tensile strength, 119.38±14.26% elongationand 25.49±0.72% resilience.

R esearchers recently gathered at Tsinghua University in Beijing, China, to share their accomplishments at the 13th annual ACM Conference on Ubiquitous Computing. 1 This multidisciplinary conference featured advances in sensing technologies and activity-recognition algorithms, novel applications, and results from end-user evaluations. Smartphones continued to provide a versatile research platform, facilitating application delivery, sensor data capture, and computational social science on captured data. For many years, capturing sensor data at any scale involved substantial effort and expense. However, dependable smart-phones and robust mobile networks are dramatically reducing data-collection costs. A robust, embedded GPS, for example, lets researchers gather large datasets of human movement on a city-wide scale. A computational analysis of these location traces lets researchers examine previously hard-to-see social patterns in the aggregate. Location Analysis: Tacking Taxis GPS-equipped taxicabs provide continuous , dynamic reports of driver and passenger location as they traverse city road networks. The routes selected and flow of movement effectively function as mobile traffic sensors. Yu Zheng and his colleagues examined how this sensing capability can support urban planning. They learned Beijing traffic patterns using GPS traces from 30,000 taxis and correlated them changes that urban planners had made to the road network. By visualizing the difference between expected and actual changes to traffic patterns, they can help urban planners reflect on the actual outcomes of their plans. In a similar project, Daqing Zhang and his colleagues used GPS traces to learn common taxi trajectories and developed an anomaly-detection algorithm with over 90 percent accuracy. Their algorithm can help identify when changes occur in the road network, which could help commuters respond to dynamic traffic situations and help regulators identify taxi fraud. Looking to optimize taxi-passenger services, Jing Yuan and his colleagues looked to use sensing to make taxis more economic and convenient for both the drivers and passengers. Their algorithm, which compares models of taxi and pedestrian movement, can offer recommendations to drivers as to where to find passengers and can help pedestrians find taxis. As an alternative to GPS, which can be unavailable or unreliable, Richard Becker and his colleagues demonstrated that driving routes can be accurately classified using only cellular handoff patterns. They presented results of their two algorithms, demonstrating that cellular handoff patterns are stable across different routes, speeds, directions, phone models, and weather conditions. Healthcare Applications Researchers at Ubicomp 2012 demonstrated that mobile phones can facilitate the sensing of a great …

Computer Simulation of Urban Runoff Characteristics Within Salt Lake County by Robert Newman Parnell, Jr. , Master of Science Utah State University, 1971 Major Professor: Dr. J. Paul Riley Department: Civil Engineering A hybrid computer program is developed to simulate the outflow hydrographs of two urban watersheds located within Salt Lake County, Utah. The gaged outflow of the watersheds provided a checkpoint for comparing the observed and the simulated final outflow hydrographs. The outflow hydrographs for each subzone of the two watersheds were obtained by abstracting interception, infiltration and depression storage from each subzone hyetograph. The outflow of the subzones were routed to the Jordan River, the final outflow point of the two watersheds. The final hydrographs of the watersheds were combined and compared with the gaged flow. The uniquenesses of this systems model are the flexibility in varying hyetographs, variable loss rates, combination of subzone hydrographs, and the combination of watershed hydrographs. Subzone hydrographs can also be plotted for visual inspection as well as obtaining numerical values. With a variety of input and output data, designers


The objective of this study was to evaluate the effect of wheat flour substitution with toasted corn, quinoa, and sorghum flours on the overall perception and texture of typical Spanish small cakes named madeleine. In order to evaluate these characteristics, a texture profile analysis (TPA) and a sensory analysis were carried out. TPA showed that the replacement of wheat flour by sorghum flour did not affect significantly texture parameters of cakes. Hedonic sensory tests were also conducted revealing that the cake prepared with sorghum flour was highly appreciated by the consumers as it got scores similar to traditional cakes made with wheat flour.


he risk of postoperative neurosensory impairment after extraction of a third molar will be greater if the inferior alveolar nerve is in close roximity to the apices of the root. Precise preoperative evaluation of the relative positions of the nerve and the mandibular apices is important o protect the nerve from mechanical irritation. The aim of this study was to assess the accuracy of cone-beam computed tomography (CT) n the identification of the positional relations of the mandibular third molar and the inferior alveolar canal using Rood's criteria. Panoramic images of 10 dry hemimandibles were obtained, and 20 teeth each with one of Rood's criteria indicating close relations to he mandibular canal were selected. Cone-beam CT images of the selected points were obtained. The closest distance between the apex of he root and the inferior alveolar canal was measured on cross-sectional cone-beam CT images. The same measurements were made on the orresponding osteometric sections with digital callipers. The intra-class correlation coefficient (ICC) was used to measure the consistency etween the two measurements as the reference method, and showed that there was a high level of inter-rater agreement (r > 0.90). The mean SD) deviation of cone-beam CT measurements from the gold standard osteometric measurements was small at 0.30 (0.24). There were almost erfect matches between cone-beam CT and gold standard measurements. Cone-beam CT is an accurate technique to measure the proximity f the mandibular apices to the alveolar nerve. 2016 The British Association of Oral and Maxillofacial Surgeons.

Tilapia guineensis , a typical estuarine cichlid species in the West Coast of Africa, is an important fish species in view of its immense contribution to the nutritional needs, economic growth, and development of many African nations including Nigeria. Knowledge of current level of diversity and genetic structure of T. guineensis populations in Nigeria is lacking. This knowledge will be useful for improvement through selective breeding. In the present study, morphological and molecular techniques were used to characterize and investigate genetic diversity of this species for breeding and conservation purposes. Six hundred and twenty samples were collected from six coastal states namely Rivers, Delta, Lagos, Ondo, Akwa Ibom and Bayelsa in Nigeria. Two locations were selected per state to study intra and inter specific variations making a total of twelve locations. Three morphological methods (morphometric, meristic and truss network data) were used for determination of phenotypic variation while ten microsatellite markers were utilized for genetic diversity assessment. DNA was extracted and subjected to polymerase chain reaction (PCR) amplification and polyacrlamide gel electrophoresis (PAGE) for allelic separation and genetic differentiation. Physicochemical characteristics of sampling stations were determined to assess the environment of the organism. The physicochemical parameters investigated are water temperature, pH, conductivity, salinity, dissolved oxygen (DO) and biological oxygen demand (BOD). Physico-chemical samples were collected using standard procedures and samples analyzed using standard techniques. Physicochemical characteristics investigation reveals that all physicochemical parameters were within ranges of international permissible levels in water. This implies a satisfactory physicochemical regime during the study period, suggesting the water bodies still have a positive integrity to support aquatic life. Principal component analysis (PCA) revealed two principal components (PC-1 and PC-11) that accounted for 90.3% of observed variation in morphometric attributes; 58.1% and 58.8% in meristics and truss network system respectively. When compared to other locations, fish in Iwoama had the highest mean weight of 0.29+0.006 kg with a mean total length of 0.24+0.002 m. variability the morphological stocks of T. guineensis and should be recommended for differentiating T. guineensis , especially when combined with the other two morphological methods. The study established that Buguma in Rivers state, Badagry in Lagos state and Brass in Bayelsa state populations have higher genetic diversirty and are therefore identified as suitable areas for sourcing T. guineensis for fish improvement through appropriate breeding and conservation. However, Oron and Ibaka in Akwa Ibom state populations had the lowest biodiversity necessitating conservation efforts.


In this study, we demonstrate the capability to detect microscopic stable displacement nature created by proton irradiations with a method based on the discrimination of the three major low frequency noise sources generally observed in semiconductor devices. Low frequency noise measurements are carried out in silicon in-situ phosphorus doped polycrystalline silicon serpentine resistance used as test vehicle. We observe that for the pristine sample, the voltage noise power density can be explained only considering 1/f and thermal noise contribution on the total noise, while for irradiated sample generation recombination noise prevails. Preliminary results on low frequency noise spectroscopy, used as a diagnostic tool in order to identify stable traps created by protons irradiations are presented.


Combined the theories of thermodynamics and thermoacoustics,the structure of the pulse tube- one of the most important components in the pulse tube cryocooler- was analyzed.The function of the structure of pulse tube in the distribution of the gas temperature and pressure along the tube has been found. Two kinds of the tapered pulse tube structures have been proposed accordingly in this thesis and have been investigated numerically. It has been found that there is an optimum cone angle for the tapered pulse tube cryocooler. When the pulse tube cryocooler works on this optimum cone angle,the performance can be improved.The convergent and the divergent tapered pulse tubes were submitted and validated in the numerical simulation and the experiment.


An in-situ plasma processing technique has been developed at the Spallation Neutron Source (SNS) to improve the performance of the superconducting radio-frequency (SRF) cavities in operation. The technique uses a lowdensity reactive neon-oxygen plasma at room-temperature to improve the surface work function, to help removing adsorbed gases on the RF surface and to reduce its secondary emission yield. Recently, the plasma processing technique has been applied to one offline cryomodule and to two cryomodules in the linac tunnel. Improvement of the accelerating gradient has been observed in all three cryomodules.

In this review article, the synthesis methods and application research progresses of the lanthanide sulfides are summarized and commented, especially the structures, properties and applications of the g-Ln2S3. Several comments on the problems existed in the research of lanthanide sulfides had been given out, and the development trends in this field are proposed.


Standard potentials (Eθ) of the silver–silver chloride electrode have been determined at 25°C in ethylene glycol and in its approximately isodielectric mixtures with 20, 40 and 60 wt. % acetonitrile, from e.m.f. measurements performed on the cell Pt, H2(g, 1 atm.)/HCl(m), solvent/Ag–AgCl. Standard free energies of transfer (ΔGθt), of HCl at 25°C from ethylene glycol to acetonitrile + ethylene glycol mixtures, obtained from these measurements have been interpreted in terms of the acid–base nature of the solvents. Comparison of the ΔGθt-composition profile with those of other isodielectric solvent systems has been used to confirm the idea of ion desolvation caused by dipolar aprotic solvents like acetonitrile.


osting by E Abstract Khat chewing is a recreational habit known to pose major socio-economic and medical problems in countries of Southern Arabia and the Horn of Africa. Among other adverse health effects, khat chewing has been associated with an increased risk of myocardial infarction (MI) in heavy consumers. This study was carried out to examine the direct effects of Catha edulis extract on contractility of spontaneously contracting, isolated rabbit heart and to investigate its mechanism of action. Isolated six rabbit's hearts attached to a Langendorff apparatus were perfused with extract at a constant flow rate and continuously bubbled with a 95% O2/5% CO2 gas mixture. Each heart served as its own control, as responses were recorded before and after administration of C.

Treatment data from a sample of over 25 clinics throughout the UK, indicates safe operation of the Lumina during more than 10,000 treatment procedures.


Hepatobiliary and pancreatic malignancies frequently involve major vessels such as the inferior vena cava (IVC), hepatic vein, portal vein and foregut arteries, especially the hepatic artery. Tumours involving these structures are often considered unresectable and the patients incurable. Early efforts to include vascular resections as part of hepatectomy and pancreatectomy were associated with increased surgical morbidity and mortality, but recent studies from high-volume centres have shown that combined vascular resections can be undertaken safely with acceptable morbidity and mortality. In turn, this might lead to better outcomes in selected patients. The retrohepatic IVC may be involved by direct invasion in the context of hepatic metastases, intrahepatic cholangiocarcinoma and gallbladder carcinoma. Hepatocellular carcinoma is often associated with intracaval extension of tumour thrombus. Surgical resection of hepatic metastases involving the IVC was reported in 16 patients from Chiba University in 19991 when surgical morbidity and mortality rates were 25 and 6 per cent respectively, with a 5-year survival rate of 27 per cent. In the past few years, European series from Leeds2 and Paris3 have reported IVC resections combined with hepatectomy, with surgical mortality rates between 11 and 14 per cent, and a 5-year survival rate approaching 40 per cent. In a series of 60 patients undergoing combined IVC resections with hepatectomy, including ex vivo procedures in six, Hemming and colleagues4 had a surgical mortality rate of 8 per cent with 35 per cent 5year survival. Replacement of the cava may be necessary after circumferential resection5 in patients who before surgery have poor development of a collateral circulation, when oliguria occurs or if haemodynamic stability cannot be maintained during surgery. Portal vein resection as a component of hepatectomy is sometimes necessary for patients with intrahepatic cholangiocarcinoma, hilar cholangiocarcinoma and gallbladder cancer. The Chiba series reported in 20076 showed that combined vascular resection was performed in 43 of 161 patients with hilar cholangiocarcinoma who underwent surgical resection. Surgical mortality rates were 4 and 8 per cent in the non-vascular resection and portal vein resection groups respectively, but the 5-year survival rate was 25 per cent after portal vein resection. Interestingly, if hepatic artery resection was also needed in an attempt to achieve clear margins, survival was the same as that in patients with unresectable disease. Neuhaus and co-workers7 also reported longterm survival after combined portal vein resection for hilar cholangiocarcinoma with a 5-year survival rate of 58 per cent. On the contrary, Nagino et al.8 reported that hepatectomy with simultaneous resection of the portal vein and hepatic artery for advanced perihilar cholangiocarcinoma resulted in favourable long-term outcomes with acceptable mortality. However, most publications suggest that surgical mortality rates lie between 2 and 15 per cent, but with a beneficial effect on long-term survival in patients with hilar cholangiocarcinoma. A systematic review and meta-analysis9 of the role of vascular resection in the treatment of hilar cholangiocarcinoma demonstrated that increased morbidity and mortality was due mainly to the addition of hepatic artery resection compared with portal vein resection alone. This review also showed that routine vascular resection did not always improve negative resection margin rates and had no impact on long-term survival. From this point of view, portal vein resection should not be undertaken routinely and done only where there is suspicion of cancer invasion. Combined hepatic arterial resection results in higher morbidity and mortality with no proven survival benefit and should therefore be performed in select patients. Portal vein resection as part of pancreatectomy is now widely regarded as a safe and feasible procedure with acceptable morbidity and mortality rates. Combined portal vein resection with pancreatectomy should be considered where there is a suspicion of invasion of the portal vein to achieve clear resection margins on the basis of preoperative imaging rather than making the decision purely on operative findings. Unlike the situation with hepatic resections, combined arterial resections involving the coeliac axis, at least in the context of distal pancreatectomy, have been reported without a marked increase in surgical mortality. Distal pancreatectomy with en bloc


The family is traditionally excluded from patient treatment in the hospital. This article describes a unique approach and setting for family inclusion and participation in health care prior to the patient's hospital discharge.


Head and neck squamous cell carcinoma (HNSCC) is globally the seventh most common cancer. Its 40–50% 5-year survival rate has not improved significantly in the last decade despite surgical, radiotherapy and chemotherapy progress. Significantly increased knowledge of biomarkers and molecular biology of HNSCC has shown that smoking and alcohol consumption cause HNSCC and that the human papilloma virus (HPV) is related to HNSCC oncogenesis. Tumor/node/metastasis (TNM) staging is essential to determining treatment and prognosis. Even early-stage subjects may have recurrence and/or distant metastasis. New biomarkers should provide new categories and staging determing prognosis preoperatively by routine tumor biopsy that, in turn, will improve HNSCC management. Here we review molecular biology of HNSCC and discuss potential analysis and treatment.


Crude carbon nanotubes prepared with D.C.arc discharge and catalytic methods were purified in order to get high-pure CNTs.Efficient methods for purification of CNTs were used with individual choice,such as microporous membrane,toluene extraction,dense hydrochloric acid flush,oxidation in mixed acid,and oxidation in air according to the different characteristics of the imparities in three kinds of deposits(spider web-like substances,rubbery films and rod-shaped deposit),so that CNTs with mass fraction of more than 90% could be obtained.Furthermore,these purified nanotubes were observed,analyzed,and characterized by means of TEM,TGA,and Raman spectrum.The result indicated that the purification methods presented could result in high recovery ratio,high purity,mild oxidation condition,and easy control of test in contrasted with other ones.


The use of a segmented conical plain bearing for the application as main bearing in a wind turbine offers multiple advantages. The main bearing can be designed very compact. In addition, in case of a main bearing damage, individual bearing segments can be exchanged on the tower without the use of an external crane, in contrast to the repair procedure of rolling bearings. It is well known from conventional applications of plain bearings that the bearing clearance has a major influence on the load carrying capacity. Therefor the realization of narrow tolerances in the manufacturing of the bearing components is necessary. In this paper, the influence of the manufacturing tolerances on the performance of conical plain bearings is investigated. The influence of the tolerances on the load carrying capacity can be determined by conducting elastohydrodynamic (EHD) simulations. Finally, an evaluation of the robustness of the conical bearing concept against manufacturing-related deviations is carried out.

The developed unit aims at the application in fully active automotive chassis in combination with hydraulic shock absorbers. The very special requirements of this application resulted in a new development with numerous detailed solutions which are described below. Parallel and interacting with the product development, all new series assembly and testing devices tailored to this product was developed.


Objective: To investigate the expression of transmembrane protease, serine 4(TMPRSS4) and its clinical signii cance in gastric cancer.Methods: h e mRNA and protein expressions of TMPRSS4 in 33 specimens of gastric cancer along with their adjacent tissues were measured by real-time RT-PCR and Western blot analysis, respectively. The TMPRSS4 expressions in 108 paraffin specimens of gastric cancer along with their adjacent tissues were determined by immunohistochemical staining, and the relations of TMPRSS4 expression with the clinicopathological proi les and prognosis of gastric cancer patients were analyzed.Results: Both the TMPRSS4 mRNA and protein levels in gastric cancer tissue were significantly higher than those in adjacent tissues(both P0.05). TMPRSS4 expression rate in gastric cancer tissue was signii cantly higher than that in adjacent tissue(55.56% vs. 18.52%)(P0.05), and high TMPRSS4 expression was significantlyrelated to the tumor size(≥5 cm), depth of invasion, TNM stage and lymph node metastases(≥3)(all P0.05). Kaplan-Meier survival analysis showed that the 5-year overall survival in TMPRSS4 expression patients was poorer than that in low TMPRSS4 expression patients(P=0.035). Cox analysis revealed that the high TMPRSS4 expression was an independent prognostic factor for gastric cancer patients(P=0.045).Conclusion: h e TMPRSS4 level is closely associated with the progression of gastric cancer and could be used as a potential prognostic marker for gastric cancer.


A travelogue can be regarded as a location-oriented or scene-based document. Visualizing a pure textual travelogue with location-based images makes it convenient for readers to understand the main content of the travelogue and thus share the author's experience. Though a large number of images exist in web albums such as Flickr, they are not directly, explicitly associated with a travelogue. In this paper, we propose a general framework and four approaches to accomplish the visualization task. The first step of the framework is to extract location names and other location-related information from a travelogue (or a set of travelogues). In the second step, we use the location names as queries to retrieve candidate images together with their tags from Flickr. In the last step, the retrieved images are carefully refined by using a proper similarity function. The similarity function measures the similarity between the travelogue and the tags of each candidate Flickr image. In addition to the framework, our main contributions lie in three topic models which are used for computing the similarity functions. The models are not only adopted to visualize a single travelogue but also employed to summarize a collection of travelogues. Experimental results on a set of Chinese travelogues demonstrate the proposed methods' ability to visualize travelogues.


This paper presents the methodologies for synthesis and characterization of a new class of low loss Fe3O4-PDMS polymer nanocomposites, which exhibits well-tailored magneto-dielectric properties. Single crystalline Fe3O4 nanoparticles with a small size distribution of 7.5 ± 2nm were prepared by chemical precipitation method to retain the superparamagnetic characteristics and the Fe304-PDMS nanocomposites with uniformly dispersed Fe3O4 nanoparticles at three different loading concentrations of 80 wt%, 50 wt%, and 30 wt% were explored. Room-temperature magnetization measurements were conducted for the plain Fe3O4 nanoparticles and these Fe3O4-PDMS nanocomposites using a physical properties measurement system (PPMS) while extraction of microwave properties in wide range frequencies between 1GHz and 8GHz under different levels of externally applied magnetic field was performed by using a custom-built transmission line test fixture. The 80 wt% Fe3O4-PDMS nanocomposites under 0.37T of biasing field have exhibited coveted magneto-dielectric properties at 4GHz, by showing an equal-valued relative permittivity εr and relative permeability μr of 3.0. It is worthwhile mentioning that the peak relative permeability of 3.55 along with fairly low dielectric and magnetic loss tangents less than 0.02 were obtained under 0.2T DC biasing field. These newly-characterized Fe304-PDMS nanocomposites were used for successful implementation of miniaturized patch antennas, which is going to be reported subsequently.


In order to reduce PtSi Schottky barrier height (SBH) for electron, we investigated modulation of PtSi work function by alloying with low work function metal, such as Hf (3.9eV) and Yb (2.7eV). Pt (10-20nm)/Hf, Yb (0-10nm)/n-Si(100) stacked structures were in-situ deposited at room temperature by RF magnetron sputtering method. In case of PtxHf1-xSi formed at 400°C/60min annealing in N2, SBH for electron was reduced from 0.85eV to 0.53eV with Hf thickness without increase of sheet resistance. Yb incorporation also affected the SBH modulation, however, the sheet resistance increased with increase of Yb thickness.


Introduction: The lipoblastoma is a rare benign tumor with only nine cases reported with presentation in the face and neck. Originates from embryonic cells fats to continue their proliferation in the postnatal period. The age of presentation average is three years and usually occur in limbs and trunk. Clinical presentation and radiation may be similar to that of linfagioma, however, it is important to reach preoperative diagnosis because the lipoblastoma can resected without functional consequences. Clinical case: a Patient of the female sex of a year four months of age, which began its clinical picture in April 2006 to the three months of life, with the presence of mass supraclavicular left approximately 8 x 7 cms, not painful, not adhering to deep planes of consistency soft, with image studies (US and TAC ) It was diagnostic as linfagioma, so it is administered OK 432 on three occasions, in spite of which the mass increased in size, so that decides its surgical resection . The specimen measured 21 x 15 x 9 CMS and weight 1300 grs. With evolution postoperative satisfactory. Discussion: The appearance of clinical lipoblastoma neck has several similarities with the linfagioma quistico; age, location in region later cervical and consistency. However handling is very different from what is important to note the patterns to achieve and thus help to the pediatric surgeon to improve the results in the handling of both entities.A lipoblastoma has an excellent prognosis despite its size, and the high rate of growth and its trend limited to invade neighboring tissue. Index Words: Lipoblastoma neck; OK 432; Linfagioma.


Quantum discord quantifies nonclassical correlations beyond the standard classification of quantum states into entangled and unentangled. Although it has received considerable attention, it still lacks any precise interpretation in terms of some protocol in which quantum features are relevant. Here we give quantum discord its first information-theoretic operational meaning in terms of entanglement consumption in an extended quantum-state-merging protocol. We further relate the asymmetry of quantum discord with the performance imbalance in quantum state merging and dense coding.

Though sustainability is very important concept, it is very difficult to define it quantitatively. This study aims to quantify regional environmental capacity and long-term growth by using koku of rice data. The results show that metropolitan region has suffered heavy environmental loads. The model to investigate environmental load factors indicates that the environment preservation and regional growth are both side of the same paper, a kind of antinomy. The effect on regional environment and growth by disasters and infrastructure are also examined by using this model.


Cell replacement therapy is the only method that can cure Type 1 diabetes, but the critical shortage of available donor tissue impedes this therapeutics in clinic application. So the study of regulating differentiation of stem cells toward mature, functional islets cells becomes the hotspot recently. This article reviewed related advances in this field, and focused on the gene regulation of islet cell development and differentiation and also the actions of some bioactive molecules on the induction of stem cells to differentiate toward the β-like cells of pancreatic islet and their action mechanisms.


A mathematical model for plane waves propagating through an optical fiber is developed. This model is based on linear algebraic methods and refers to the far-infrared frequencies. From the concept of power signal, a linear operator is constructed. This operator is established by means of the transfer function of the fiber in the time domain. The matrix associated with the operator is a mathematical entity which is useful in order to perform computer programs. Furthermore, the linear operator is studied as a map between Banach spaces; in particular, the norm of this map is calculated


At the end of the 1960s, when native Canadian publishing developed a crusading fervor with the appearance of new avant-garde enterprises like the House of Anansi and New Press, experimental fiction became a vogue in Canada in a way anticipated by only a few isolated works of earlier decades like Sheila Watson's The Double Hook (1959) and Howard O'Hagan's Tay John (1939). Perhaps the great publishing event of the waning decade, because it made us aware of a strong nouvelle vague of discontent among younger writers with accepted forms, was Anansi's launching of Spiderline Editions, an inspiration on the part of Dennis Lee, but in some ways a self-defeating one. It was a series devoted entirely to "first novels," and for a couple of years it tapped hitherto unexploited sources of imaginative energy, but then the flow of brilliant available material dried up and the series came to a quiet end.


It is supposed that the grain boundary precipitation behaviour of chromium carbide and the decrease of corrosion resistance of the welded parts in austenitic stainless steel, with both thermal and strain cycles are different from those in the parts with only thermal cycle.The effects of stress at elevated temperatures on corrosion resistance in stressd and unstressed specimens (SUS 304) at sensistization temperatures were investigated for different keeping times. The results obtained are as follows:(1) It was recognized that the decrease of corrsoion resistance was promoted by the keeping stress at elevated temperatures (500°-800°C).(2) The longer the heating time, the more distinctive was the difference in decrease of corrosion resistance between the stressed and unstreassed specimens at 700°-800°C; it also became more distinctive as the stress was larger or the thermal and strain cycles were longer.(3) It was also recognized that the corrosionof the restrained parts of weldments were more serious than that of the unstrained parts.


Picosecond dynamics of Re → polypyridine 3MLCT excited states of [Re(Etpy)(CO)3(dmb)]+ and [Re(Cl)(CO)3(bpy)] were investigated by time-resolved UV−vis, resonance Raman, and IR spectroscopy. Raman bands due to NN•- intraligand vibrations of the excited molecules increase with time during the first 15−20 ps after excitation. The time constant of 6 ± 2 ps was estimated for the increase of areas of excited-state Raman bands of [Re(Etpy)(CO)3(dmb)]+. The growth of Raman bands is accompanied by an increase of the near-UV transient absorption band at 375 nm, which corresponds to a ππ* transition of the dmb•- ligand of the 3MLCT excited state [ReII(Etpy)(CO)3(dmb•-)]+. These effects are attributed to structural reorganization during vibrational cooling, during which the electronic dipole moment and/or vibrational overlap integrals increase. IR bands due to CO stretching vibrations and some of the Raman bands undergo dynamical upward shift and narrowing, that occur with time constants between 1 and 11 ps, manifes...

Scalp acupuncture has been widely applied to clinical treatment of infantile cerebral palsy. It mainly includes Jiao's, Tang's, Jing's and Lin's schools of scalp acupuncture. This article arranges literature published in recent years and discusses the theoretical basis for point formation and its practical characteristics in different systems of scalp acupuncture. It has been found: (1) The theory on which the distribution and formation of point areas were based is different, including Zang Xiang, and cerebral function location and neurophysiology in modern medicine. (2) The theory about point prescription, the depth of needle insertion, needling manipulation and the time for needle retention have different characteristics in different schools. (3) In the selection of scalp acupuncture system, generally one school was used as a main method, but in some cases two or more methods were also combined for use. To improve the clinical effect of scalp acupuncture on infantile cerebral palsy and further standardize its application, strict and scientific design and comparative observation of the combined application modes and performing procedures in different systems of scalp acupuncture are urgently needed in clinical research.


The measurement system used to provide process control and material accountability in the recovery of neptunium from irradiated reactor fuels requires a variety of analytical methods.

The product stream is analyzed with an alpha-count-alpha energy method. The solvent extraction waste streams are analyzed by alpha counting methods with solvent extraction purification of the sample. The loss to the fuel cladding wastes is determined from the ,137Cs content of the stream. The evaluation of the overall system is made from a statistically-based automated standards program.


In this paper we present a robust system of symbol recognition using a structural approach. Our key objective here is to provide a system, equaling the statistical ones in robustness concerning the recognition, to apply next to localization. To do it we have investigated two particular structural methods: the straight line detection using Hough Transform and the vector templates matching. Experiments done on the GREC2003 database show how their combination allows to obtain high recognition results.


Voice fonts are created and stored for a speaker, to be used to synthesizespeechinthespeaker'svoice. Themostimportantde-scriptors of voice fonts are spectral envelope for acoustic units and prosodic features such as fundamental frequency and average speaking rate. In this paper, we present a new approach to model the speaking rate so that it can be easily incorporated in voice fonts and used for personality transformation. We model speaking rate in the form of average duration for various acoustic units and categories for the speaker. The speaking rate can be automatically extracted from a speech corpus in the speaker's voice using the proposed approach. We show how the proposed approach can be implemented, and present its performance eval-uation through various subjective tests.

Abstract IT governance is critical to most organisations and has an influence on the value generated by IT investments. Unfortunately, IT governance is more aspiration than reality in many organisations. This research seeks to address the dearth of empirical evidence about IT governance in practice, presenting the findings of an IT governance case study in an Australian organisation. Recommendations are provided to assist organisations to maximise potential of IT governance and insights are provided for researchers.


Context. ALMA observations of protoplanetary disks confirm earlier indications that there is a clear difference between the dust and gas radial extents. The origin of this difference is still debated, with both radial drift of the dust and optical depth effects suggested in the literature. Aims. In thermo-chemical models, the dust properties are usually prescribed by simple parametrisations. In this work, the feedback of more realistic dust particle distributions onto the gas chemistry and molecular emissivity is investigated, with a particular focus on CO isotopologues. Methods. The radial dust grain size distribution is determined using dust evolution models that include growth, fragmentation, and radial drift for a given static gas density structure. The vertical settling of dust particles is computed in steady-state. A new version of the code DALI is used to take into account how dust surface area and density influence the disk thermal structure, molecular abundances, and excitation. Synthetic images of both continuum thermal emission and low J CO isotopologues lines are produced. Results. The difference of dust and gas radial sizes is largely due to differences in the optical depth of CO lines and millimeter continuum, without the need to invoke radial drift. The effect of radial drift is primarily visible in the sharp outer edge of the continuum intensity profile. The gas outer radius probed by (CO)-C-12 emission can easily differ by a factor of similar to two between the models for a turbulent alpha ranging between 10(-4) and 10(-2), with the ratio of the CO and mm radius R-CO(out)/R-mm(out) increasing with turbulence. Grain growth and settling concur in thermally decoupling the gas and dust components, due to the low collision rate with large grains. As a result, the gas can be much colder than the dust at intermediate heights, reducing the CO excitation and emission, especially for low turbulence values. Also, due to disk mid-plane shadowing, a second CO thermal desorption (rather than photodesorption) front can occur in the warmer outer mid-plane disk. The models are compared to ALMA observations of HD 163296 as a test case. In order to reproduce the observed CO snowline of the system, a binding energy for CO typical of ice mixtures, with E-b >= 1100 K, needs to be used rather than the lower pure CO value. Conclusions. The difference between observed gas and dust extent is largely due to optical depth effects, but radial drift and grain size evolution also affect the gas and dust emission in subtle ways. In order to properly infer fundamental quantities of the gaseous component of disks, such as disk outer radii and gas surface density profiles, simultaneous modelling of both dust and gas observations including dust evolution is needed.


Consumers are currently demanding less use of artificial additives in food products, so more attention had been paid to search for naturally occurring substances that are anticipated to be safe and health-promoting. This is true for plant materials that act as alternative sources of many bioactive compound. Doum palm (Hyphaene thebaica) is one of the underutilized fruits that contains many valuable compounds. Doum fruit should be regarded as potential source of natural antioxidant, antimicrobial, dietary fiber, and more, capable of offering significantly low cost and nutritional compound that are safer for human consumption and their use in food products will increase quality and added value. Foods that possess additional physiological effects beyond their nutritional functions of providing nutrients are called functional foods. Functional food can provide nutraceuticals with the therapeutic value that is capable of protecting against various diseases. From this point of view, the present study was designed to review literatures on the natural source of valuable compounds in doum palm fruit.


AIM: To study the pharmacokinetic characteristics of pazufloxacin mesylate in healthy volunteers. METHODS: Ten healthy volunteers received a single dose of 300 mg of pazufloxacin mesylate by intravenous injection. The plasma concentrations of pazufloxacin mesylate were determined by HPLC method. RESULTS: The concentration-time curve after administration was best fitted to two-compartments open model. The main pharmacokinetics parameters of pazufloxacin mesylate were as follows: T max, ρ max, T 1/2β, AUC (0-8) were (0.52±0.17) h, (6.63± 1.86) mg/L, (1.90±0.24) h, and (13.42±2.96) h·mg/L, respectively. CONCLUSION: Pharmacokinetic study shows that pazufloxacin mesylate has short half-life and high concentration in plasma. Effective concentration by intravenous injection can be achieved after two or three dose of 300 mg pazufloxacin mesylate per day.


The status quo for objective function design in reinforcement learning (RL) is to use the value function of a Markov decision process (MDP). But this prescribes RL agents with an additive utility function, which is not obviously suitable for general purpose use. This paper presents a minimal axiomatic framework for rationality in sequential decision making and shows that the implied cardinal utility function is of a more general form than the discounted additive utility function of an MDP. In particular, our framework allows for a state-action dependent "discount" factor that is not constrained to be less than 1 (so long as there is eventual long run discounting). We show that although the MDP is not sufficiently expressive to model all rational preference structures (as defined by our framework), there exists a unique "optimizing MDP" whose optimal value function matches the utility of the optimal policy. The relation between the value and utility of suboptimal policies is quantified and the implications for objective function design in RL are discussed.


ABSTRACT Transnational feminist media studies has a prominent role to play in tackling the normativization of binary gender and sexuality templates that lend coherence to the Global Right's epistemological universe. Feminist scholars can begin to interrupt the traveling script at some of its most vulnerable points. The brief example here is the glaring divide between populist leaders' seemingly invulnerable political masculinities and their actual weakness, which the HBO mini-series allegorically exposes.


ABSTRACT This paper reports on an investigation of a Higher Education institution's webpages for prospective students. The study is used to illuminate how different conceptions of internationalisation are, or are not, represented to home and international students in university marketing. Multimodal Critical Discourse Analysis (CDA) is used to investigate the webpages' discursive strategies through detailed analysis of linguistic features and images. The research explores how discourses frame or sideline conceptions of internationalisation, and it shows that in this case the dominant discourse of internationalisation is a narrow and exclusionary one. The paper concludes that in the webpages of this non-elite university a broader version of internationalisation is being marginalised in a neoliberal climate perhaps because it cannot be quantified, does not fit the individual consumer model, and so is squeezed out under the pressures of other discourses.


In order for two haploid yeast cells to undergo normal fusion during mating, adhesive contacts are formed by a general class of fungal proteins termed "adhesins". Within this family there is a subgroup of cell wall proteins termed "agglutinins" which are known to mediate aggregation, thereby increasing mating efficiency in liquid medium (Aga1p, Aga2p, Agα1p). In the absence of sufficient mating adhesive contacts we observed that cells undergo defective morphogenesis, apparently continuing to grow at their tips after fusing at the expense of laterally expanding their conjugation bridge. Based on these qualitative observations, I utilized differential interference microscopy to capture micrographs of mating cells of different mutants that lacked one or more of the yeast adhesin/agglutinin proteins Aga1p, Aga2p, Fig2p, and Agα1. From the micrographs collected, I determined the relative dimensions of the mating cells and analyzed them using various statistical methods. The study elucidated the necessity of these proteins for proper morphogenesis. In a related project I sought to identify cell wall genes whose inactivation led to deficiencies in mating when the mating partner lacked specific adhesins. Cell wall residency of the adhesins and the remodeling that the cell wall undergoes during cell-cell fusion are important and incompletely understood processes whose components might affect such crosses. I performed a large scale genomic screen of strains known to be defective in some aspect of cell wall organization. A collection of 170 cell wall mutant strains, each containing a replacement of a single yeast gene with a dominant drug resistance marker, was tested for mating deficiency in crosses to wild type and adhesion deficient partner strains. From this screen seven candidate gene mutations were identified that reproducibly satisfied the screen and hold promise for further study.


Cancer is a complex disease of the genome exhibiting
myriad somatic mutations, from single nucleotide changes to various
chromosomal rearrangements. The technological advances of
next-generation sequencing enable high-throughput identification
and characterization of these events genome-wide using
computational algorithms. Retrotransposons comprise 42% of the
human genome and have the capacity to "jump" across the genome in a
copy-and-paste manner. Recent studies have identified families of
retrotransposable elements that are currently active. In fact,
retrotransposons constitute a major source of human genetic
variation, and somatic retrotransposon insertions have been
implicated in several cancers, including an insertion into the APC
tumor suppressor in a colorectal tumor. Because of the highly
repetitive nature of these elements, however, the full extent of
somatic retrotransposon movement across cancer remains largely
unexplored. To this end, we developed TranspoSeq, a computational
framework that identifies retrotransposon insertions from
paired-end whole genome sequencing data, and TranspoSeq- Exome, a
tool that localizes these insertions from whole-exome data.
TranspoSeq identifies novel somatic retrotransposon insertions with
high sensitivity and specificity in simulated data and with a 94%
validation rate via site-specific PCR. Next, we applied these
methods to wholegenomes from 200 tumor/normal pairs and
whole-exomes from 767 tumor/normal pairs across 11 tumor types as
part of The Cancer Genome Atlas (TCGA) Pan-Cancer Project. We
discover more than 800 somatic retrotransposon insertions primarily
in lung squamous, head and neck, colorectal and endometrial
carcinomas, while glioblastoma multiforme and acute myeloid
leukemia show no evidence of somatic retrotransposition. Moreover,
many somatic retrotransposon insertions occur in known cancer
genes. TranspoSeq-Exome uncovers 35 additional somatic
retrotransposon insertions into exonic regions, including an
insertion into an exon of the PTEN tumor suppressor in endometrial
cancer. Finally, we integrate orthogonal genomic and clinical data
to characterize features of retrotransposon insertion and samples
that exhibit extensive somatic retrotransposition. We present a
large-scale, comprehensive analysis of retrotransposon movement
across tumor types using next-generation sequencing data. Our
results suggest that somatic retrotransposon insertions may
represent an important class of tumor-specific structural variation
in cancer and future studies should incorporate this form of
somatic genome aberration.


In this study we investigated the physico-mechanical properties of alumina nanoceramics, that is used as substrates in micro- and optoelectronics chips. The elastic characteristics (Young's modulus E, shear modulus G, Poisson's ratio v, microhardness H) are determined by measuring the longitudinal and transverse wave velocities. The results suggest that the nanoceramics have unique properties that can be used in the future microelectronics to improve the stability of chips and to optimize the production technology.


The invention relates to a process for the preparation of superabsorbent polymers (SAP) by alkaline hydrolysis of polyacrylonitrile by precipitation polymerisation (PAN-precipitation polymer).


The invention provides a preparation method of beta-crystal form silodosin. The preparation method comprises the following steps: adding silodosin into an organic solvent, heating in nitrogen till the refluxed solution is clear, naturally cooling to crystallize after 30 minutes, filtering to obtain white solid, and drying at about 40 DEG C in vacuum, wherein the X-ray powder diffraction spectrum shows that the crystal form of silodosin is beta, the purity is 99.6-99.7%, and the melting point is 105-106 DEG C. The method can stably prepare the beta-crystal form silodosin, and is high in yield and applicable to industrial production.


A standardized vessel design is being considered at the Waste Treatment and Immobilization Plant (WTP) that is under construction at Hanford, Washington. The standardized vessel design will be used for storing, blending, and chemical processing of slurries that exhibit a variable process feed including Newtonian to non-Newtonian rheologies over a range of solids loadings. Developing a standardized vessel is advantageous and reduces the testing required to evaluate the performance of the design.The objectives of this paper are to: 1) present a design strategy for developing a standard vessel mixing system design for the pretreatment portion of the waste treatment plant that must process rheologically and physically challenging process streams, 2) identify performance criteria that the design for the standard vessel must satisfy, 3) present parameters that are to be used for assessing the performance criteria, and 4) describe operation of the selected technology.Vessel design performance will be assessed for both Newtonian and non-Newtonian simulants which represent a range of waste types expected during operation.Desired conditions for the vessel operations are the ability to shear the slurry so that flammable gas does not accumulate within the vessel, that settled solids will be mobilized, that contents can be blended, and that contents can be transferred from the vessel. A strategy is presented for adjusting the vessel configuration to ensure that all these conditions are met.Copyright © 2015 by ASME


Background: The purpose of the study was to investigate the effect of high frequency rTMS with constraint induced movement therapy (CIMT) on Upper extremity motor function. Clinical Stroke Assessment Scales and fMRI was used to assess the response of CIMT with rTMS on blood oxygenation-level dependent (BOLD) sequence component. Methodology: RCT was conducted at All India Institute of Medical Sciences, New Delhi, on chronic stroke patients (N=60) between 12 to 36 months of index event with atleast 10° of wrist extension, 10° of thumb abduction, Brunnstorm stage 2-4; NIHSS 4–20. Patients were randomized to CIMT alone (Group A n=30) & rTMS with CIMT (Group B n=30). rTMS (10 Hz, 750 pulses with 110%RMT) was administered for 3 weeks (5days/week). Radiological Assessment of the patients was done with fMRI (BOLD) along with assessment of Fugl Meyer (FM), Barthel Index, and modified Rankin Scales (MRS) at baseline, 3 weeks (Post intervention) & 3 month (follow up) Results: FM showed statistically significant improvement in group B as compared to group A at 3 weeks (95%CI: -12.4 to -9.3, p=0.003) and 3months (95%CI: 7.4 to 4.2, p=0.01). Repeated measure ANOVA showed that the mean groups were different at all-time points indicating some degree of improvement in all the subjects (F=3.4, p=0.01; F=5.4, p=0.002). The BOLD cluster activation was compared between two groups; there was increase in the number of clusters found in Group B. Conclusion: Both the groups showed improvement, increased cluster count showing alterations in cortical activations (fMRI-BOLD) after CIMT with rTMS in patients with chronic stroke indicated more degree of clinical improvement in upper extremity function.


INTRODUCTION Graduate education in medicinal chemistry and pharmacognosy focus on the interdisciplinary application of chemical, biochemical, and molecular principles to the identification and development of therapeutic agents. Research and graduate education in medicinal chemistry emphasize drug design and include the synthesis of organic medicinal products, elucidation of the biochemistry and molecular biology of medicinal agents, examination of the relationship of chemical structure to biological activity, qualitative and quantitative analysis of drugs, and application of computational chemistry to drug design. Research and graduate education in pharmacognosy emphasize drug discovery and encompass isolation and structure elucidation of pharmacologically active natural products from plants and microbes, examination of the biosynthesis of natural products, and evaluation of the biochemical effects of these active constituents. The graduate and research program areas of drug macromolecule interactions, drug design based on biochemistry and biotechnology, and bioassay-directed drug discovery are examples of important growth areas for medicinal chemistry and pharmacognosy. This perspective on the future of graduate education in medicinal chemistry and pharmacognosy addresses several issues. First, the impact of trends in Colleges of Pharmacy and in doctorate research universities on graduate programs in medicinal chemistry and pharmacognosy will be discussed. Secondly, the perspectives of the pharmaceutical industry and of academia will be summarized. Third, a training program for the PhD degree in medicinal chemistry and pharmacognosy will be discussed. Finally, personal perspectives on the importance of benchmarking and on


Sufficient conditions have been developed for testing the optimality of solutions to all-integer and mixed-integer linear programming problems after coefficient changes in the right hand side and the objective function, or after introduction of new variables. The same conditions can be used as necessary conditions for coefficient changes to alter an optimal solution. The tests are based on cutting-plane theory, and the application of the tests requires solution of the original integer problem with a cutting-plane algorithm.


ABSTRACT This essay enhances the broad context in which Karen Offen's argument is framed by addressing the question of how the humanities are faring today in relation to academic research and learning. I explore what that context means specifically for women's history and vice-versa into the future. Secondly, I provide a historical overview of how women's history in Romania has developed since 1989. My analysis highlights the slow and uneven shift from complete invisibility to some interest and a small number of excellent books in several areas of research, from demographic to political history of the modern period.


From the dawn of the Cold War, the point at which the issue of Arctic sovereignty first gained national prominence, to the present day, Canadian governments have consistently voiced their uncompromising dedication to the defence of Canada's northern heritage.  However, historically, Canadian policy has never matchedits rhetoric in the Arctic.  In an age where competition in the Arctic is becoming more intense, with states vying for control of vast natural resources and potential shipping lanes, the issue of Arctic sovereignty can no longer be one of secondary concern.  Canada can no longer dismiss the burdens which go hand-in-hand with sovereignty.  It must decide how important the Arctic tryly is to the nation and be ready to stand behind that decision.


A set of three experiments are described that examine the sources of information processing that produce a dissociation between subjective workload measures and performance. The results support a theory of the dissociation. Subjective measures are driven more by the number of tasks currently performed. Subjective measures are also less sensitive to resource competition than performance measures are. Factors that demand more resource investment improve performance, but these factors also increase subjective ratings of workload.


Many elements contribute to pre-service teachers' experiences in learning to teach mathematics. The transition to remote learning during the COVID-19 pandemic has forced educators to challenge traditional math instruction. This chapter presents three major contributing elements in pre-service teacher preparation to foster creativity as a central component and an inevitable outcome of learning to teach mathematics with particular applications to online learning settings. The first section discusses learning to teach math as a creative activity. Some concrete instructional strategies are offered that promote dialogue-rich learning environments. The second section reviews current trends in learning to teach math. The author posits pre-service teachers who have suffered traumatic experiences in learning mathematics must first acquire tools for clearing math anxiety and fear. The third section is a call to action to encourage teachers to participate in and construct learning communities to teach mathematics including the use of instructional technology to support online instruction.


Website is one of the main components of the Internet, therefore those who are able to create website may able to influence, share, sell, advertise their or their company/organization content or products. Especially during the Covid-19 era everything information or business has become available online. This community service aimed to teach and bring awareness of CMS, a non coding method and system that can help user to create website quite fast. One of the advantages of WordPress is that it can be used for various websites and applications. For example, you can use WordPress to create a simple website, to a business website. For business websites, one of the plugin modules provided by WordPress is Woocommerce. With Woocommerce users can make WordPress display into an online store or online store quite easily. According to the questionnaire the training gave user a new perspective that creating and publishing website is isn't that complicated after all when using Wordpress.


Wagner, Chen, and Barnett (2003 [this issue]) rightly identify the U.S. Department of Veterans Affairs' (VA's) historical lack of uniform cost data as an important barrier to economic analyses within the VA. Their article is an important contribution, and the cost estimates they generate should facilitate many types of health services research. At the same time, there are some aspects of their method that may limit the appropriateness of the cost estimates for certain types of analyses. We discuss several such aspects here. The model estimates costs in the long run, meaning it assumes all costs are variable. In the VA, however, managers often must make decisions that are essentially short run in nature. For example, managers are often unable to close facilities or even buildings due to political constraints. If the model had adopted a short-run perspective (i.e., treating some costs as fixed rather than variable), some of the parameter estimates (for example, the marginal cost of an extra day of hospitalization) would be expected to decline substantially. The reason for this is that fixed costs are high relative to variable costs in the short run (Schwartz and Mendelson 1991, 1994; Taheri et al. 1998, 1999; Taheri, Butz, and Greenfield 2000a, 2000b; Williams 1996; Reinhardt 1996; Roberts et al. 1999). For truly long-run analyses, in which it is appropriate and important to consider costs that managers consider fixed in the short run, cost estimates using the Wagner, Chen, and Barnett (2003) methodology are likely to play a


ABSTRACT The effect of Ultraviolet radiation type C (UV-C) radiation (0.100 ± 0.010 J/cm2) on shelf life of Arapaima gigas fillets stored at 4 ± 1°C for 18 days was investigated. The samples were analyzed for total aerobic mesophilic bacteria (TAMB) counts; total aerobic psychrotrophic bacteria (TAPB) counts; Enterobacteriaceae; purge loss; pH; lipid oxidation; total volatile bases (TVB-N); ammonia; biogenic amines (BAs); and L*, a*, and b* values. UV-C radiation increased (P < 0.05) the generation time of all bacterial groups evaluated, increasing the shelf life by 2 days. UV-C-treated fillets showed lower (P < 0.05) L* values, purge loss, pH, TVB-N, ammonia, and BAs levels than their control counterparts throughout the storage period. Moreover, UV-C treatment did not result (P > 0.05) in detrimental effects on lipid oxidation or a* and b* values. UV-C at 0.100 J/cm2 demonstrated a good potential for use in A. gigas fillets and, therefore, it could be applied at industrial scale.


Manitoba cancer patients are heading to the US for treatment because of a shortage of radiation therapists. The therapists, who had been without a contract since October 1999, finally signed a new 4-year deal in late July.

Colorization is a process that converts a grayscale image into a color one that looks as natural as possible. Over the years this task has received a lot of attention. Existing colorization methods rely on different color spaces: RGB, YUV, Lab, etc. In this chapter, we aim to study their influence on the results obtained by training a deep neural network, to answer the question:"Is it crucial to correctly choose the right color space in deep-learning based colorization?". First, we briefly summarize the literature and, in particular, deep learning-based methods. We then compare the results obtained with the same deep neural network architecture with RGB, YUV and Lab color spaces. Qualitative and quantitative analysis do not conclude similarly on which color space is better. We then show the importance of carefully designing the architecture and evaluation protocols depending on the types of images that are being processed and their specificities: strong/small contours, few/many objects, recent/archive images.

The selective addition of C_(60) and polyarylamine was studied. The mono-cycloadduct and tris-cycloadduct were successfully synthesized by 1,3-dipolar cycloaddition. They can be separated by HPLC with toluene and methanol (V∶V=1∶1) as the mobile phase. By using AM1 semiempirical quantum calculation method, the geometry, electronic structures and frontier orbitals of N-methyl-pyrrolo[3,4] C_(60) derivatives have been studied. The results indicate that the frontier orbitals of the derivative molecules were dominantly determined by the C_(60) moiety, rather than the fulleropyrrolidines. For these derivatives, there exists strong intramolecular electron transfer. The C_(60) moiety is an electron acceptor while the organofunctional groups are electron donors.


This paper proposes fluid animation method which analyzes flow field from fluid video. While current fluid animations relies on fluid simulation, this paper propose effective process which calculates 2d velocity field of smoke motion in video without fluid simulation. We utilize PCA to synthesize intermediate frames between sequential input fluid image sequences. We generate optical flow for fluid movements using a groundbreaking optical flow estimation method which is the combination of Lucas/Kanade and Horn/Schunck to achieve the best of the local and global differential methods.
