A new numerical scheme in the finite-element method was used to simulate both the progressive nature of failure and the interaction of the soil–root matrix continuum under dry and fully saturated conditions. Computations suggested that a certain range of root area ratio (the effective RAR range, or ERAR range) should be identified for a given slope geometry, vegetation type and maturity period. The ERAR range represents all the RARs that impart a factor of safety (FOS) greater than or equal to a particular FOS (the benchmark FOS). The benchmark BMFOS is the anticipated FOS, depending on factors such as demographic distribution and proximity to utilities. Beyond the ERAR range, vegetation does not impart stability to the slope. Theoretically, higher ranges of RAR beyond the ERAR range (the ineffective RAR range) can cause slope failure. This new numerical scheme evaluates the root-reinforcement effect on slope stability. This information is useful for analysing, designing and implementing soil-bioengineeri...


Chemical technology company Avantium partnered with nova-Institut GmbH under the framework of the PEFerence project1, to perform a full cradle-to-grave Life Cycle Assessment (LCA) for the YXY Technology, assessing the potential environmental impacts of PEF packaging solutions in comparison to conventional PET alternatives. The LCA is performed according to the ISO 14040/44 standard methodology. A critical peer review of the study, including by experts of incumbent technologies, was conducted in order to verify whether the LCA met the requirements for methodology, data, interpretation, and reporting. In this paper, the main results of this LCA study are summarised.


We propose a distributed architecture for knowledge revisionintegration, where each element is conceived as a knowledgebased system able to exchange information with the others. since nodes can be affected by some degree of incompetence, part of the information running through the network may be incorrect and might cause contradictions in the knowledge base of some nodes. To manage these contradictions, each node is equipped with a belief revision module which makes it able to discriminate among more or less credible information and more or less reliable information sources. Our aim is that of comparing on a simulation basis the performances and the characteristics of this distributed system vs. those of a centralised architecture. We report here the fmt results of our experiments.


The static properties of code repositories, e.g., lines of code, dependents, dependencies, etc. can be readily scraped from code hosting platforms such as GitHub, and from package management systems such as npm for JavaScript; Although no less important, information related to the dynamic properties of programs, e.g., number of tests in a test suite that pass or fail, is less readily available. The ability to easily collect this dynamic information could be immensely useful to researchers conducting corpus analyses, as they could differentiate projects based on properties that can only be observed by running them. In this paper, we present npm-filter, an automated tool that can download, install, build, test, and run custom user scripts over the source code of JavaScript projects available on npm, the most popular JavaScript package manager. We outline this tool, describe its implementation, and show that npm-filter has already been useful in developing evaluation suites for multiple JavaScript tools.


Here, we ask a simple question, i.e. "at what cosmic time, at the earliest, did life first appear in the universe?" Given what we know about the universe today, there may be some partial answers to this question, but much will still have to be left to speculation. If life in general requires stars as its primary energy source and uses elemental building blocks heavier than those initially produced in a Big Bang scenario, first life could have appeared, when the universe was considerably less than 0.1 billion years old. At that time, heavy element producing hypernovae exploded at corresponding redshifts.} $z$\,\gapprox\,45, significantly higher than commonly assumed ($z \approx 6$). The recent discovery of a galaxy at $z > 9$ could provide supporting evidence for the hypothesis of a very much shorter time scale than what is widely believed.


We present the change oriented model of versioning, which focuses strongly on functional changes in a software product and therefore can be seen as an alternative to the traditional, "version oriented" models. The change oriented model is used as a basis for the versioning in the EPOS software engineering database, which features an integrated transaction and versioning mechanism.


The aim of the study was to analyze the relationship between emotional reactivity, exposure to trauma and its interaction, and posttraumatic stress disorder (PTSD) symptoms in motor vehicle accident (MVA) survivors. Both emotional reactivity and exposure to trauma were expected to be significant predictors of the intensity of PTSD symptoms. Exposure to trauma was considered as a total score but also as successive indexes, such as threat to life during an accident, injuries sustained in the aftermath of an accident, emotions felt during an accident, dissociation experiences, and the amount of material losses. Emotional reactivity was also expected to play the role of moderator, increasing the positive relationship between exposure to trauma and PTSD symptoms in people characterized by higher emotional reactivity. The analyses were performed in two separate samples. The first sample consists of 458 MVA survivors who had a traffic collision up to six months before the study. The second sample (n = 674) comprises MVA survivors who had an accident more than six but less than twentyfour months before the study. The correlation and regression analyses revealed that, as expected, both emotional reactivity and exposure to trauma are significant predictors of PTSD symptoms, which explained about one-third of total variance of symptoms. The hierarchical regression with interactions between emotional reactivity and exposure to trauma also supports the hypothesis that emotional reactivity can be a moderator and the MVA survivors who are more emotionally reactive develop more intensive PTSD symptoms when confronted with severe and stressful experience.

This book explores the vision, foundation, and enabling technology required to successfully transform organizations with enterprise architecture.


Component-based software development technique and its extensive application have led to the wide research in various aspects of component-based software (CBS). The rapid evolution of CBS brings great challenges to its maintenance in the later phase, so it is quite necessary to measure the change impact on the whole system. By using component dependence matrix to represent component-based software system, the paper mainly discusses the case of component modification, including the single component change and the changes of multi-components, and proposes the corresponding algorithms (i.e. Appxm RM, Generate_SP, and Calculate_CR) for analyzing the change impacts in CBS. In addition, the calculation process of change impact analysis and its effectiveness are also validated by a simple CBS.


We show that the pT spectra measured in pp collisions at the LHC exhibit geometrical scaling introduced earlier in the context of deep inelastic scattering. We also argue that the onset of geometrical scaling can be seen in nucleus-nucleus collisions at lower RHIC energies.


Objectives: Evaluate the efficacy of combined anti-staphylococcal and anti-pseudomonal preoperative antibiotics for preventing surgical site infections following tympanoplasty and mastoidectomy (TM) with contaminated cholesteatoma. Methods: Study Design: Retrospective chart review Method: Medical records of patients who underwent TM for cholesteatoma were reviewed. Only cases considered to have contaminated or dirty/infected surgical fields were included. Patients were excluded if there was preexisting infection or intraoperative finding requiring systemic antibiotic therapy. The primary outcome measure was postoperative perichondritis, pinna abscess, peri-otic cellulitis, and peri-otic abscess requiring systemic antibiotics or surgical intervention. Results: The charts of 362 patients who underwent TM were reviewed. 195 met inclusion criteria. Preoperative antibiotics included clindamycin and ceftazidime or gentamicin. Patients treated with no perioperative antibiotics had an infection rate of 11% and those treated with perioperative antibiotics had a rate of 1% (P = .02). Conclusions: The use of preoperative antibiotics to cover staphylococcal and pseudomonal species prevented surgical site infections as compared to no perioperative antibiotics.


Development of electromagnetic compatible rugged launch computer (RLC) system in rack mountable form for missile launch application is very critical for stringent electromagnetic environments defined by military standard. Often, the system does not meet the electromagnetic compatibility (EMC) requirements even after implementing all the possible EMC measures at the design stage. The EMC engineers observes the electromagnetic interference (EMI) performance of the system during formal compliance testing and analyses all possible reasons for any failures and then apply fundamental EMI mitigation techniques with standard suppression components and implement innovative EMC measures. In this paper the authors have shared their experience in achieving EMC of a RLC system for missile application during formal compliance testing phase.


Taking into consideration of the characteristics of teaching Chinese as a second language(TCSL),this paper maintains that the range of discrimination of word meanings in TCSL should be wider than that in Chinese lexical research.This point of view has been proved in terms of form and meaning.Therefore it is not necessary to adhere to the range of the latter in TCSL vocabulary teaching.To widen the range of discrimination of word meaning is in accordance with the objective demands and needs of foreign learners.Based on a review of the problems that exist in the discrimination of word meanings,four principles for it are suggested,i.e.the discrimination should be simple and practical,clear and easy to understand,connected of what has been learnt and what is going to learn,and finally,focused on key issues.

Swiss ball exercise has been used for various purposes at present. It has been for improvement of physical fitness, concentration ability, balancing ability, health-related physical fitness. It is accepted that Swiss ball exercise have differences with others physical exercise. At the same time Swiss ball has been included in multi gym. Considering the nature of equipment and benefits girls are getting interested with ball exercises. An exercise ball, also known as a Swiss ball, is a ball constructed of soft elastic with a diameter of approximately 35 to 85 centimeters (14 to 34 inches) and filled with air. It is most often used in physical therapy, athletic training and exercise. Balls are cheaper equipment, easy to handle, easy to maintain, and soothing to exercise with. Considering the above benefits the equipment could be very much suitable for women or girls, but very few studies have been conducted in this area and so the problem was designed in such a manner just to infer the "The impact of Swiss ball exercise programme on fitness of school girls". For the present study 30 school girls aged between 15-25, who were selected randomly from Madanpur Panchayat area as subjects. From data analysis it is clear that the performance of the girls with regard to the fitness variables developed significantly due the training.

Four lanthanide(III) nitride bismuthides of the new class M2NBi (M = La–Nd) have been synthesized by the reaction of the respective lanthanide metal (M) with caesium azide (CsN3), elemental bismuth (Bi), the corresponding lanthanide trichloride (MCl3), and caesium chloride (CsCl) as flux in evacuated silica tubes for 7 days at 900 °C. The M2NBi compounds crystallize tetragonally in the space group P4/nmm with Z = 2 with the lattice parameters a = 480.61(4) pm, c = 948.34(9) pm (M = La), a = 475.48(4) pm, c = 938.76(9) pm (M = Ce), a = 471.80(4) pm, c = 929.51(9) pm (M = Pr), and a = 468.13(4), c = 921.08(9) pm (M = Nd). As the main structural feature of the crystal structures, ∞2{[NM2]3+} layers of condensed nitride-centered square pyramids of M3+ cations dominate. These pyramids, in which the base is built of (M1)3+ and the top of terminal (M2)3+ cations (t), are connected by all four basal edges (e) to form a two-dimensional network according to ∞2{[N(M1)e4/4(M2)t1/1]3+} that is separated by square double layers of Bi3– anions. Both crystallographically independent M3+ cations bear two types of anions (N3– and Bi3–) as ligands. (M1)3+ is coordinated in the shape of a square antiprism by four N3– and four Bi3– anions, and (M2)3+ is surrounded by a distorted octahedron consisting of one N3– and five Bi3– anions. The Bi3– anions reside in capped square antiprisms of nine M3+ cations. The partial density of states (PDOS) and the band structure of La2NBi show that this compound has to be considered as a zero-band-gap semiconductor with a nontrivial topology and a high potential as a topological insulator.


Carolina in the USA have been exploring the use of the extreme-permittivity dielectric barium titanate (BaTiO3) perovskite oxide to increase breakdown voltage and to reduce resistance in aluminium gallium nitride (AlGaN) electronics [Towhidur Razzak et al, Appl. Phys. Lett., vol116, p023507, 2020]. AlGaN is of interest in power electronics as a widebandgap semiconductor with a high critical breakdown electric field value of more than 9MV/cm (when the aluminium content exceeds 50%), good low-field electron transport characteristics, and high saturation velocity. Such features could enable high-power, highfrequency radio signal generation, along with allowing the handling of high power densities in electronic circuitry. However, realizing these potential benefits in actual performance requires meeting a number of challenges for device structures with nonuniform field distributions. The researchers see BaTIO3 as having benefits for device scaling, enabling AlGaN-based transistors to access radio frequency (RF) performance. The team explains: "Extreme-permittivity dielectrics enable improved breakdown due to two reasons. First, a high-dielectric-constant layer greatly reduces the peaking or non-uniformity in the lateral electric field between the gate to drain for lateral transistors or anode to cathode for lateral diodes and results in a higher breakdown voltage and higher average breakdown field due to a more uniform electric field distribution." The researchers also point to potential high-breakdown benefits from BaTiO3 use in gallium oxide (Ga2O3) structures. Due to the wider bandgap of these materials being associated with lower electron mobility compared with GaN, the team suggests that scaling would compensate for high sheet resistance. Further, the use of high-k dielectrics in transistor gate stacks enables better electrostatic control of carrier flow in channels with lower output conductance and higher transconductance. A potential drawback of high-k materials is extension of the drain depletion region and an increase the gate-to-channel capacitance. Such factors would tend to reduce cut-off frequencies. The researchers comment: Technology focus: Power electronics

Objective
To evaluate the double-point labeling under ultrasonography for right internal jugular vein puncture cannulation in infants.

Methods
One hundred and twenty infants scheduled for surgery were randomly divided into 3 groups(n=40): traditional anatomical location group (group M), patients′ right internal jugular vein puncture, were cannulated by using the traditional method of palpation of carotid pulsation and identification of other anatomic landmarks. Real-time ultrasound guidance group (group C), a two-dimensional ultrasound scanner image made for locating the puncture site of vessels was used with an operative probe of PHILIPS CX30 system, L12-4 probe unit, real-time boot operation. Ultrasound pre-labeling followed by operation group (group L), an ultrasonic pre-locating two points, which made for locating the puncture site of vessels was used with an operative probe of PHILIPS CX30 system, L12-4 probe unit. The number of attempts, success rate and incidence of complications were compared among three groups.

Results
There was no significant difference in one-time success rate between group C and group L, but the rates of both groups were higher than the rate of group M (P<0.05). There was no significant difference in puncture times between group C and group L, but the times of both groups were lower than the time of group M (P<0.05). Also, there was no significant difference in operation time between group C and group L, but the times in both groups were less than the time of group M (P<0.05). The main complications were puncture hematoma and arterial injury, the incidence of hematoma and arterial injury in group M were significantly higher than that in group C and L (P<0.05).

Conclusions
Two points pre-localization under ultrasonography for the right internal jugular vein puncture is superior to the anatomic landmark technique in terms of successful rate and complications.

Key words:
Infants; Ultrasound; Internal jugular vein puncture


A wideband 2×2-slot element for a 60 GHz antenna array is designed by making use of air filled cavity fed by inverted microstrip gap waveguide. The designed element is a triple layer structure in which the upper layer contains four radiating slots backed by an air-filled cavity. The cavity is excited by a coupling slot fed by an inverted microstrip gap waveguide formed in the air-gap between the middle and lower layers. The designed 2×2-slot element is considered in an infinite array environment. A sample 32×32 slot array aperture is simulated using infinite array approach. The results show that the mismatch is better than -15 dB and the directivity larger than 38 dBi over 56.3-67.9GHz frequency range, i.e. 20.7 % bandwidth.


Reference material (RM) is defined as a material, sufficiently homogeneous and stable with respect to one or more specified properties which has been established to be fit for its intended use in a measurement process. RM is one of the tools used to assess laboratory performance on an ongoing basis, as quality control in conducting testing and can be used to calibrate an equipment and to validate or verify the testing method. Currently microbiological reference materials with fish matrices are not much available so that there is a need for RM with fisheries matrices specification. Comprehensive studies of homogeneity and stability are need to be able to develop of any reference material. Initially, a feasibility study revealed a suitable processing procedure for fish matrix, the fish protein hydrolysate (FPH) was prepared by enzymatic hydrolysis, freeze-drying, and milling. Microbiological reference material with fish matrix were shown to be sufficiently homogeneous, and storage at temperatures of -20°C for 4 weeks statistically showed the effect of storage time (P value that was significant at 5% significance level). These results provide the basis for the development of a RM for Salmonella in fish matrix.


A number of investigations are recorded in the literature reporting that it is possible to stain nuclei in vivo (see reviews, Alexandrov, '33 ; Becker, '36). Nevertheless, it is generally held that the nucleus of the living cell resists staining and that staining of the nucleus indicates cell damage or even cell death. This is because in most of the studies dealing with the vital staining of nuclei, the cells were stainable only under deleterious conditions. Thus, Nassoiiov ( '30, '32), Alexandrov ( '33), Kamnov ( '34), Malrarov ( '34), Gersch ( '31), Ries ( ' 3 7 ) , and others, working particularly with neutral red, produced staining of nuclei in vivo by submitting the cells to such conditions as anoxia, acidosis and hypertonicity. I n contrast to this, Ellinger and Hirt, in a series of papers ('29, '30, '31) primarily dealing with the excretion of fluorescein and acriflavine (trypaflavine) in the liver and kidney of the f rog and the liver of the rat, reported that the nuclei of the cells of these organs stained in vivo with acriflavine, without any special treatment. Their studies were carried out on living organs in situ by means of vertical illumination.


sThe Travelling Salesman Problem (TSP) consists of finding the lowest cost or the shortest path tour between cities. In the theory of computational complexity, the TSP belongs to the class of NP-complete problems and is one of the simplest but most intensively studied problems in optimization. Even though the problem is computationally difficult, a large number of heuristics and exact methods are known. In this presentation, we propose a new heuristic algorithm for the asymmetric TSP. It is well known that NNA is very sensitive to the starting city. We basically use the first iteration of the Modified Vogel Method (MVM) in order to determine the best-starting city for the Nearest Neighbor Algorithm (NNA). Note that the resulting solution tour can be considerably improved. This can yield, in some cases, to the optimal solution.


A method and apparatus are disclosed for interpolating pixels (80) to obtain subpels for use by a video decompression processor. A prediction area (90) is defined from which subpels are necessary to decompress a portion of a video image. Instead of reading all of the pixels from the prediction area and then processing them together to perform the necessary interpolation, portions of the pixel data are read and simultaneously averaged using in-place computation in order to reduce hardware requirements. Rounding of subpixel results is achieved using the carry input of conventional adders (114, 116, 118, 120, 148) to add a binary "1" to the averaged pixels, which are subsequently truncated (150) to provide the interpolated subpels.


Vip3A proteins are widely used for controlling pest Lepidoptera. Different binding sites with different receptors in the insect midgut membrane and lack of cross-resistance with Cry proteins enhance their applicability, as both single proteins and proteins pyramided with Cry proteins in transgenic Bt crops. Vip3A proteins are effective but there is relatively little information about their structure, function, activation, specificity, and mode of action. In addition, the mechanism of insect resistance to these proteins is unknown. Phylogenetic analysis and multiple sequence alignment showed that Vip3A proteins are genetically distant from Cry proteins. The mode of action and insecticidal activity of Vip3A proteins are discussed in this review. This review also provides detailed information about the Vip3A protein family that may aid in the design of more efficient pest management strategies in response to insect resistance to insecticidal proteins.

Current tube plate stamping die usually have some common problems, which include low standardization, low standard penetration and long mold design cycle. By analyzing stamping die used in the refrigeration industry, the cold-drawing dies blanking needs to be designed and optimized. Compared with the previous design methods, the method, that the Pro/E plug-PDX was used to design cold-drawing dies blanking with refrigeration equipment, has a lot of advantages. First, cycle was shortened to one-third of the original; second, the compound pressing method is able to reduce the pressing step and increase stripping device, in order to improve the reasonable structure and production efficiency. The new method proposed in this paper is able to increase design efficiency, shorten design cycles, reduce workload and improve the accuracy of the mold design, and reduce the cost of mold design.


Deep Convolutional Neural Networks (CNNs) have recently demonstrated the state-of-the-art classification performance on ImageNet Large Scale Visual Recognition Challenge (ILSVRC) since 2012, yet there is relatively no clear understanding of the reasons behind their outstanding performance, or how they might be improved, In this paper we present a novel benchmarking of multiple state-of-the-art deep CNN architectures by providing an analysis of important performance metrics: speed, memory consumption, and network parameters utilization. Key findings are: (1) fully connected layers are of a high cost on speed and memory consumption compared to the sparsely connected layers; (2) the depth and the performance of an architecture are in a nonlinear relationship and constrained by layers transformation types; (3) 1×1 convolutions are an efficient way to reduce dimensionality and pooling features; (4) addition units as in residual and densely connected networks accelerate the backpropagation time by distributing the gradients through the graph, we believe our set of benchmarks are a step towards better realization of the best architectural design choices of Deep CNNs.


We explore the role of the gluon condensate in matching Regge models to the operator product expansion of meson correlators.


This article compares color preferences with a context to color preferences without it, using chips of 50 colors and the shape of an automobile as the context. Subjects were asked to make preference judgments of the color chips with the shape and also without it in the experiment. Multi- variate analyses were performed on the two sets of data to deriue latent spaces of color preference with and without the context. Through interpretation and comparison of the derived spaces, it was found that there was a noticeable context effect between the preference judgments.


The invention discloses a dilute nitric acid preparing method meeting the requirements of energy saving and emission reduction as well as low cost and a device. The method comprises the steps of adding the high-concentration nitric acid into the low-concentration nitric acid for intensive mixing by circulating reflux, blowing compressed air into the mixed nitric acid, extracting undissolved nitric oxide gas until the mixed nitric acid reaches the required concentration of dilute nitric acid, stopping reflux, stopping introducing the compressed air, and sending the undissolved nitric oxide gas to a water tank to be absorbed by water to form a nitric acid solution. The dilute nitric acid preparing method adopts a mode of air stripping of ascending compressed air flow and descending recycled acid countercurrent so as to avoid the discharge of a large number of waste water and waste gas in the acid preparation process and effectively reduce the cost for acid preparation. The dilute acid preparation device of the invention has simple structure and is operated conveniently. The invention protects the environment, saves energy, has obvious economic and environmental benefits, and has popularization value when preparing the industrial dilute nitric acid.


The article analyses the qualification improvement of social workers, who work in children's care homes, in the context of their restructuring. A qualitative-empirical study has been conducted by using the method of a semi-structured interview. The study data were processed by using the method of content analysis. The results of the empirical study are based on the experience of 14 social workers, who work in care institutions, which participate in the restructuring, which consists of the changeover from institutional care to the services that are provided to children, who have become destitute of parental care, in a family and community. I n ternal (an aspiration for a continuous qualification improvement and the desire to share professional experience) and external (changes related to the restructuring, ever higher requirements for social wo r kers, the encouragement and support of the administration of institutions to improve their qualification) stimuli to improve qualification have been highlighted. The most relevant topics of qualification improvement for social workers are the development of personal and social skills in children, the preparation of them for an independent life, the solution of behavioural and psychological problems in children and the preparedness of social workers themselves for the restructuring and the need for supervisions. The topics, which  meet their needs, are: the development of s ocial skills, the communication with children and the preparation of them for a family. According to the informants, there is a lack of trainings oriented towards the solution of practical problems which arise while organizing the restructuring. The following problems related to the improvement of qualification were highlighted: the mismatch between t he teaching topics and the content, during the trainings for social worker, who work in children's care homes, the problems of other social groups, but not of children are analysed. During trainings, there is a lack of the detailed examination of the solution of pra c ti cal problems . The s ocial workers lack trainings related to the preparation for the restructuring .


Purpose: The main aim of this study was to examine and analyse the body composition of young soccer players across different age groups.
Methods: A cross-sectional study was carried out among 126 young soccer players divided into age categories: U15 – 53 players (age=14.68±0.47); U17 – 51 players (age=16.47±0.50); U19 – 22 players (age=18.05±0.38). The subjects' height was measured using an anthropometer, while their body composition was measured using the TANITA BC-420MA digital scale.
Results: On average, soccer players in the U15 group had significantly lower body height, weight, body mass index and fat free mass than U17 and U19 players, but had a higher percentage of body fat (p < 0.05). In addition to the percent of body fat mass, which tends to significantly decrease with age, the results also demonstrate significant non-linear increases in body height, weight, and lean body composition concurrent with the players' ages.
Conclusion: These results indicate that younger soccer players have lower absolute values of morphological characteristics compared to senior players.


By a turn of legal fate, the first case between two American states to be decided by either the International Court of Justice or its predecessor, the Permanent Court of International Justice, is one which involves the controversial practice of diplomatic asylum. One can choose to regard diplomatic asylum as a principle of American international law or as a "permissive local custom," though in no sense a principle of international law, or one can agree that "the fact that asylum is not exercised in the territory of the leading states, and is mainly resorted to in the 'backward' countries of the Near and Far East and of Latin America, suggests that it is a practice followed only in relation to states who are not fully civilized in the Western sense of the term, and that as such it is a temporary exception to the system of international law which obtains in the community of civilized nations." Whatever the viewpoint, the fact remains that the practice has been indulged in for a long time, with and without formal legal sanction, and in more places than Latin America. The Colombian-Peruvian Asylum Case brings to attention the issues of the validity in international law of diplomatic asylum and of its desirability in international relations. A short sketch of the origin and development of diplomatic asylum will indicate something of its nature.

It is shown that ethylene is the first olefin formed and ethyl methyl ether is also formed during this hydrocarbon synthesis on zeolite HZSM-5.


Background In recent years,T2DM treatment has become the focus of clinical attention. Patients' mental state is essential for the development of the disease. The medical coping can reflect patients' psychological state well. If we know patients' medical coping and find out its influencing factors,we can give patients purposive psychological guidance to gain effective treatments. Objective To investigate the medical coping in elderly T2DM patients and analyze its influencing factors. Methods This study chose,by convenience sampling method,228 elderly T2DM patients who visited 2 hospitals in Jinzhou,Chengde from November 2012 to April 2014. This study used Medical Coping Modes Questionnaire( Chinese Version)to perform the investigation. Results The T2DM patients' medical coping scores were: confrontation dimension( 18. 3 ± 3. 3),avoidance dimension( 14. 3 ± 4. 0), yielding dimension( 11. 8 ± 3. 4).

This article deals with a para-aramid fibre-reinforced composite based on Portland cement and is exposed to a high temperature loading. The main emphasis is on the residual properties after a temperature loading (of up to 1000°C). Two basic mixtures were designed, the first without para-aramid fibres and the second with them. The studied materials were exposed to three different temperature loadings and then a group of physical characteristics was determined. The designed fibre-reinforced composite could find its application as a material that improves the fire resistance of constructions, for example as boards for tunnel lining, or anywhere where a higher fire hazard or a higher temperature loading is present.


Under an EOARD contract, the DLR has conducted a series of comparative impulse measurements for two different lightcraft configurations with the same nozzle exit diameter of 10 cm: The German design (GL) is of the more conventional parabolical bell shape with a plasma breakdown region at the focal point of a parabola. The second lightcraft was supplied by the Air Force Research Laboratory (AFRL), and was designated as model 200-3/4. The experiments utilized the DLR multi-gas laser, running in CO(2) with a laser wavelength of 10.6 m. It was the goal of this investigation to extend previous atmospheric impulse measurements to a vacuum environment and to measure specific propellant consumption of the solid propellant Delrin in order to determine the exhaust velocity and the specific impulse for both lightcrafts as a function of the laser pulse energy at various pressures.

This study proposed a novel attempt to explain the effect of government support and individual's perceived susceptibility to COVID-19 in adopting e-Wallet by integrating technology acceptance model (TAM) and health belief model (HBM). A total of 232 valid responses were collected through online survey. The hypotheses were analysed and validated by using the partial least square structural equation modelling (PLS-SEM) approach. The study found that the HBM construct, which is perceived susceptibility, was only mediated by perceived usefulness. Meanwhile, government support was fully mediated by both perceived usefulness and perceived ease of use. The FinTech practitioners should consider the ease of use and usefulness of e-Wallet in fulfilling the needs of the consumers. In addition, instead of subsidising the consumers, the Government should also focus on the public facilities such as the stable connectivity that allow the consumers to stay connected and trust on the connectivity for e-Wallet. This study adopted holistic and integrative modesl which are TAM and HBM to explain the intention to adopt e-Wallet services during COVID-19 pandemic.

This study uses a postal card as a modification of the "lost letter" technique to obtain information about abortion attitudes. The message on the cards (which can be read easily by the finder) included 100 with a promise to donate money to a proabortion committee, 100 to an antiabortion committee, and 100 contained a neutral message having nothing to do with abortion. 50 of each type of card were dropped in one of two urban areas. There were more antiabortion than proabortion cards mailed, but the highest return rate of neutral cards suggests a need for additional study of abortion attitudes.


Endoscopic submucosal dissection (ESD) is well described in non-IBD (inflammatory bowel disease) patients to remove non-invasive neoplastic lesions in the colon. Data are still limited in IBD patients. One of the limited factors for the resection by ESD of dysplasia in IBD is fibrosis, which leads to an increased risk of complication such as perforation. We report a case of a 63-year-old man with a history of long-standing ulcerative colitis and multiple endoscopic mucosal resections of low-grade dysplasia in the sigmoid colon. He was referred after a new follow-up colonoscopy that revealed a non-polypoid lesion of 3 cm in the rectosigmoid junction (▶Fig. 1). The rest of the colon was free of inflammatory activity. An ESD was decided with a tractionassisted strategy to achieve R0 resection. After marking the lesion, a circumferential incision was made and a new adaptive multi-traction device (A-TRACT-2) was fixed at the two edges of the lesion (▶Video 1, ▶Fig. 2) and attached to the opposite colonic wall to optimize submucosal exposure. Depending on the level of insufflation, the degree of traction was modulated, and during dissection traction was gradually decreased. When submucosa exposure became incorrect owing to a lack of traction, a forceps was used to tighten the device, bringing all Video 1 Endoscopic submucosal resection with adaptative traction device: a new strategy to facilitate resection in patient with inflammatory bowel disease. ▶ Fig. 1 Non-polypoid lesion in the rectosigmoid junction.

This paper discusses the existence of online journalists in the midst of society in the era of globalization which is mushrooming so that their existence is considered to have sufficient advantages and disadvantages. do not make fake news to increase speed in publishing news


Human milk fat (HMF) triacylglycerols (TAGs) mainly contain palmitic acid esterified at the sn-2 position while oleic and other unsaturated fatty acids are located at positions sn-1,3. This study aimed at the production of HMF substitutes (HMFS) by lipase-catalyzed acidolysis of tripalmitin with oleic acid, in a solvent-free medium. Burkholderia cepacia lipase (BCL) was immobilized in silica (prepared with protic or aprotic ionic liquids) by covalent binding or encapsulation and used as biocatalyst. The supports and immobilized biocatalysts were characterized by FTIR, TGA, and SEM. Molecular docking analysis showed that BCL preferentially attacks oleic acid rather than tripalmitin, due to the lower free energy of hydrophobic binding with this acid (−6.5 kcal·mol−1) than with tripalmitin (5.4 kcal·mol−1). Therefore, the tripalmitin attack by BCL and subsequent HMFS production only occurs after the binding to most of the oleic acid molecules. The highest acidolysis activity was obtained with BCL immobilized by covalent binding in prepared silica with aprotic ionic liquid. A central composite rotatable design, as a function of temperature (58–72 °C) and oleic acid/tripalmitin molar ratio (MR = 2:1–6.8:1), was performed for acidolysis optimization. Under optimized conditions (58 °C and MR = 4:1 or 60 °C and MR = 2:1), the oleic acid incorporation of 28 mol.% was achieved after 48 h.


OBJECTIVE
To investigate the differential expression of the sensitive and resistant relative proteins in human breast cancer tissue.

METHODS
A drug sensitive group and a drug resistant group for chemotherapy in patients with breast cancer were selected through neoadjuvant. The differential protein expression in 2 groups was detected by proteomics techniques, and parts of differential proteins were identified by Western blot.

RESULTS
There were 13 differential proteins in the 2 groups, in which the expression of 3 proteins was up-regulated and 10 down-regulated. Seven proteins were identified by Western blot. The expression of keratin type I cytoskeletal 19 (KIC19), thymidine phosphorylase (TYPH) was upregulated, and the expression of heat shock protein 27 (HSP27), keratin type I cytoskeletal 9 (KIC9), collagen alpha-2(VI) (CO6A2), vimentin (VIME), and actin cytoplasmic 1 (ACTB) was down-regulated in the drug resistant group. There was significant difference between the 2 groups (P<0.01).

CONCLUSION
The expression of KIC19 and TYPH may be correlated with drug resistance in patients with breast cancer, and HSP27, KIC9, CO6A2, VIME, and ACTB may be correlated with drug sensitivity.


Short-term future of automated driving can be imagined as a hybrid scenario in which both automated and human-driven vehicles co-exist in the same environment. In order to address the needs of such road configuration, many technology solutions such as vehicular communication and predictive control for automated vehicles have been introduced in the literature. Both aforementioned solutions rely on driving data of the human driver. In this work, we investigate the currently available driving datasets and introduce a real-world maneuver-based driving dataset that is collected during our urban driving data collection campaign. We also provide a model that embeds the patterns in maneuver-specific samples. Such model can be employed for classification and prediction purposes.


Rationale: Although mortality from COVID-19 increases with advanced age, most older adults survive a COVID hospitalization. Disability, or dependence in functional activities, is known to increase after a serious illness among older adults, with adverse consequences for patients, families, and society. Little is known about disability, and the factors associated with disability, after a COVID hospitalization among older adults. Methods: We enrolled 341 older (≥60 years) adults during their index COVID-19 hospitalization between 7/6/2020-6/24/2021 from five hospitals in the Yale-New Haven Health System. Upon enrollment, participants underwent an assessment of baseline (prehospitalization) disability, frailty, general health, social support, hearing, vision, mental health, and assessments of current (in-hospital) symptom burden and cognitive function. These assessments were linked to EMR data including demographics, SOFA score, comorbidities, biomarkers, respiratory support, pressors, length of stay, and COVIDspecific treatments. Disability was assessed at baseline and 1, 3, and 6 months by asking about dependence in 15 basic, instrumental, and mobility activities. The primary outcome was the disability count (0-15) over the 6 months after the COVID hospitalization. The analytic sample included 304 participants who survived their hospitalization and had at least one post-discharge follow-up. We determined the mean (SD) number of disabilities over the 6 months after discharge and evaluated 27 factors for their association with the 6-month disability count using backwards selection based on minimization of the Bayesian Information Criterion with a zero-inflated negative binomial distribution and adjustment for baseline disability count and months of follow-up. Results: The mean age was 71.2 years (SD 8.5), 158 (51.8%) were women, and 108 (35.5%) were of nonwhite race or Hispanic ethnicity (Table). The mean prehospitalization disability count was 2.2 (SD 3.4), and the mean disability count over the 6 months after the COVID hospitalization was 2.9 (SD 3.7). In the multivariable model, greater baseline disability, older age, higher BMI, higher comorbidity count, cognitive dysfunction, greater symptom burden during the hospitalization, and the need for advanced respiratory support were all associated with greater disability over the 6 months after a COVID hospitalization. Conclusions: Other than the need for advanced respiratory support, factors associated with disability after a COVID hospitalization among older adults reflect vulnerability at baseline (comorbidities, baseline disability, age, BMI) or during the hospitalization (symptom burden, cognitive dysfunction), rather than biomarkers or severity of illness. These factors may identify older adults for referral to Post-COVID clinic programs to improve the likelihood of functional recovery after discharge. (Table Presented).


This work provides an analytical method, based on the Ampèrian model of permanent magnets (PM), for a fast calculation of the magnetic flux density in three-dimensional space applying Biot–Savart law, and the calculation of the forces using Lorentz's law. The applied approach enables the characterization regarding forces, torques, and stiffnesses of the levitating PM for any arbitrary position in space. Furthermore, it permits the extension of the investigation to any shape and configuration of ironless magnetic bearings (MB). In order to demonstrate the simple use of the analytical model, in this article, the dimensions of an ironless axial MB employing PMs are optimized with a multiobjective Pareto analysis, which reveals the physical limits concerning maximum achievable levitation height with respect to given constraints on, e.g., the required force and tilting stiffnesses, and the MB robustness defined by the maximum allowable payload on the levitating magnet. Moreover, the optimized axial MB and a corresponding test bench are realized to validate the proposed model with experimental results. For the sake of completeness, it should be mentioned that in a later stage, the optimized MB can also be scaled with simple scaling laws if the demanded specifications, e.g., concerning desired maximum levitation height or payload capability, would have changed.


The connection between two secondary users (SUs) in cognitive radio networks (CRNs) is not only determined by their transmission power and distance, it also depends on the availability of a common channel for both SUs to open it for communication. Due to dependency on channel availability, communication in CRNs is more challenging than traditional wireless networks. A CRN is said to be connectable if there exists a channel assignment under which all the SUs are connected by either bidirectional link or bidirectional path. In CRN, each SU is equipped with a number of antennas which is the maximum number of channels that it can open simultaneously, known as antenna constraint. As each SU has a limit on the maximum number of channels it can open simultaneously, the network may not be connectable. But, it is desirable to connect the largest subset of SUs when all the SUs of a given CRN can not be connected satisfying antenna constraint while minimizing severe interference introduced due to the nearby transmissions among SUs on the same channel. In this paper, we propose a distributed topology control algorithm with message complexity O(n2), which aims to connect the largest subset of SUs with robustness constraint (the network will not be partitioned when any primary user reclaims channel) and ensures conflict free transmissions among SUs, where n is the number of SUs. To address this NP-hard problem, we combine both topology control and channel assignment phase. In topology control phase, a network subgraph with bounded degree is derived with satisfying antenna resource constraint. In channel assignment phase, we utilize graph coloring algorithm to ensure conflict-free property. To the best of our knowledge, this is the first attempt to develop a distributed topology control algorithm when a given CRN is not connectable.


Transmission towers play an important role in the operation of a reliable electrical power system that is considered as a lifeline system. Many studies and recent earthquakes investigations have revealed that, many structures mostly transmission towers performed poorly during wind and earthquake load. Besides many contributing factors for damage, Size, depth of footing and different type's soil mainly structures on soft soil has also massive effect on structures. In case of transmission towers it should be in a straight line at some fixed distance irrespective of soil at that particular place. It is common practice in many earthquake prone areas around the world to analyse the structure using fixed base analysis. This is mainly due to lack of awareness regarding importance of SSI. In order to understand this phenomenon, a study has been performed to show the difference in response when the structure is on soft soil compare to fixed base. Two case studies have been performed to understand the above phenomenon. A 400 KV transmission tower has been design with proper section. In first case base of transmission tower assumed as fixed base. In second case a proper soil domain with infinite elements has been model using acoustic element which is good for wave propagation. Finally progressive collapse analysis (birth to death analysis) has been performed on both the case studies. Both the case studies reveal that there is great difference in response due to SSI. In second case, it was observed more number of elements is getting failed as compare to first case.


Effects of exposure to ultraviolet (UV) photons and thermal treatments on solution-processed amorphous indium gallium zinc oxide (a-IGZO) films were investigated by X-ray photoelectron spectroscopy (XPS) and photoluminescence (PL) spectroscopy. As a result, oxygen vacancies obviously become more abundant in the films sintered at 250 or 300 °C by the exposure to 7.21 eV photons and less abundant by the subsequent thermal treatment at 250 °C in air. The drain current also clearly becomes smaller in a thin film transistor fabricated using the IGZO film in a manner opposite to the abundance of oxygen vacancies. That is, the drain current becomes smaller by the UV irradiation and returns to the original high value by the subsequent thermal treatment. This indicates that oxygen vacancies act as trapping centers or scattering centers of electrons. In addition, the reversible change of the drain current with the cycle of UV irradiation and the thermal treatment opens the possibility of the use of the IGZO films as a UV sensor.Effects of exposure to ultraviolet (UV) photons and thermal treatments on solution-processed amorphous indium gallium zinc oxide (a-IGZO) films were investigated by X-ray photoelectron spectroscopy (XPS) and photoluminescence (PL) spectroscopy.

Seed dispersal through ingestion and defecation is a common occurrence for many frugivorous mammals, yet the phenomenon is understudied for small species generally thought to only be seed predators. This research investigates whether rodents ingesting small seeds through grazing herbivory can disperse seeds capable of germination and seedling establishment via defecation. Fecal samples collected as part of a small mammal live-trapping study were planted in standard germination medium and kept in a greenhouse under environmental conditions mimicking the natural habitat. While overall germination and seedling establishment was low, a small number of individual plants were able to successfully establish. This shows that small mammals can play a role in endozoochorous seed dispersal and potentially influence local plant distribution patterns.

In this paper, a rapid method for calculating the transient temperature of the hot components of gas turbines is presented, which contains the following steps: 1. The key factors affecting the heat transfer boundary conditions of the hot component are analyzed, and then link these key factors to gas turbine operation parameters, such as: compressor inlet mass flow, compressor exhaust pressure, turbine inlet gas temperature, etc.. 2. Obtain the gas turbine operation parameters mentioned above at each transient time step. 3. Based on dimensionless criterion number analysis, the external and internal heat transfer boundary conditions of the component at each transient time step are obtained by scaling those at the design point. 4. Load the external and internal heat transfer boundary conditions to the component , and solve the conduction heat transfer at each time step with a commercial CFD code. Using the method above, the transient temperature fields of the first stage segment ring of a gas turbine during a cold state start-load-stop process is calculated. The whole process shows that the transient temperature calculation method is easy to use with the computational cost bearable.


In the current market, there is a proliferation of knowledge management software (KMS) solutions. This paper discusses issues concerned with selecting such a system to support knowledge workers. Soft systems methodology (SSM) and SISTeM (Soft Information Systems and Technologies Methodology) Cycle 1 were used as problem-solving approaches within an action research framework to analyse KMS issues, human-computer interaction and the development of criteria for selecting a system. Selection criteria for KMSs are then outlined and applied to a case study in evidence-based health care.


Photonic crystals offer a well-recognized ability to control the propagation of modes of light in an analogous fashion to the way in which nanostructures have been harnessed to control electron-based phenomena. This has led to proposals and indeed demonstrations of a wide variety of photonic-crystal-basedphotonic devices with applications in areas including communications, computing and sensing, for example. In such applications, photonic crystals can offer both a unique performance advantage, as well as the potential for substantial miniaturization of photonic systems. However, as this review outlines, two-dimensional (2-D) and three-dimensional (3-D) structures for the spectral region covering frequencies from the ultraviolet (UV) to the near-infrared (near-IR) ( 2 m) are challenging to fabricate with appropriate precision, and in a cost-effective and also flexible way, using traditional methods. Naturally, a key concern is how amenable a given approach is to the intentional incorporation of selected defects into a particular structure. Beyond passive structures, attention turns to so-called active photonic crystals, in which the response of the photonic crystal 39.1 PC Overview ...................................... 1014 39.1.


Dietary fructose is implicated in metabolic syndrome, but intervention studies are confounded by positive caloric balance, changes in adiposity, or artifactually high amounts. This study determined whether isocaloric substitution of starch for sugar would improve metabolic parameters in Latino (n = 27) and African‐American (n = 16) children with obesity and metabolic syndrome.


We study the high frequency behavior of a Side Coupled Linac (SCL) formed by a large number of accelerating cells. The SCL has as basic bricks copper plates (tiles) containing on one side half an accelerating cell and, on the reverse side, half a coupling one. The electromagnetic behavior of a single tile can be represented by a two-port device made of two lumped resonant series circuits coupled by a mutual inductance. The overall SCL behavior is so described by a two-port device chain. The transmission matrix of this chain is studied. Our goal is to study the overall behavior of an SCL structure in order to find out tools useful for the design, the analysis, the diagnostics and the correction of the single cells. In this paper, we consider two-port devices which are similar but exhibit slight differences, essentially due to fabrication errors which produce deviations from cell parameter nominal values. The chain transmission matrix has been studied by means of a perturbation analysis of the circuit parameters. Results on the relevant parameters, resonance frequency of each mode and accelerating voltage in the whole structure are presented.


Rehabilitation is important for stroke patients since it helps to regain normal functionality of organs and makes patients able to live normally. This paper emphasizes on the rehabilitation of upper limb and lower limb simultaneously by using the remaining ability of patient with brain computer interface (BCI). This paper proposes rehabilitation device to assist patient for four limb rehabilitation by using hybrid software that detects Electroencephalography signal (EEG) and Electromyography signal (EMG) from patient to control the rehabilitation device. The rehabilitation follows normal physiology of human, i.e. starts by developing sensory motor, motor neuron, muscle fiber and muscle successively. Therefore, the proposed rehabilitation in this paper has advantage to the development of stroke patient with the average accuracy of approximately 80%.


The two large accidents at nuclear plants in different parts of the world in the past decade naturally cause the citizenry and even the technical community to ask just how safe the plants in the United States are. If this answer were a simple and straightforward one that they are or are not safe, I could simply say so, cite the basis, and sit down. Clearly no one expects this. The question and its reply are complex. We are all coming to recognize that safety is a relative concept and not an absolute one. Nothing is totally safe. Alternatives all carry their upside advantages and their downside hazards. Even when one alternative is to do nothing at all, that can be risky. In fact, in a great many cases of alternatives presented to solve some problem, doing nothing turns out to be the worst choice of all. Nuclear reactors have found their most important use in generating electricity in central station power plants. In this application they compete with alternate ways to make electricity through burning such fossil fuels as coal, oil, and natural gas and through hydropower. The sources of risk are completely different for nuclear plants and the competing ways of making electricity through burning fossil fuels. Most of the risk for fossil fueled plants arises during their operation and in the mining and transportation of the fuel. In the case of nuclear plants, those sources of risk are outweighed by those that could accompany a large accident releasing fission products. The limits on releases of radioactive material during operation have been set so low that they cause no appreciable source of risk. The Nuclear Regulatory Commission has adopted safety goals that are meant to codify the objectives that have guided regulatory decisions in the past and that will continue to do so in the future. These are, first, that nuclear power plants should not add significantly to the possibility of accidental death of anyone living nearby, and, second, that nuclear power should be a safer way to generate electricity than its alternatives.

Abstract
Recently, a national priority has been set to improve mental health services for children and families. It has been identified in epidemiological literature that in the United States, an approximate 15% of youth meet diagnostic criteria for emotional or behavioral problems. Furthermore, less than one in every five children that present with such needs receive mental health services. Individual, family, and system barriers such as transportation, competing demands, and long waiting lists have negatively impacted access to mental health services. Therefore, the school system has become the "de facto" mental health system for children and adolescents, in part because of the significant time students spend at school. However, meeting the needs of students with behavioral or emotional problems within the school system poses its own challenges. Schools have reported being limited in their ability to deliver basic mental wellness to students due to the lack of available resources. Specifically, there is a shortage of school-employed mental health personnel and the ratio of student to mental health professional is two to three times larger than recommended. Expanded school mental health programs are partnered systems that utilize existing services and collaborate with community mental health (CMH) professionals at each level of the three-tiered system. This partnership enables CMH staff gain access to youth with emotional and behavioral problems, resulting in increased prevention and intervention services for students. Additionally, a coordinated effort such as student-transition services has an integral role of facilitating the process from the school system to postsecondary employment, training, and or additional education.


Language is a very important tool for human communication. To be successful in speaking, people may use both verbal and non-verbal communication. Using effective communication may not be easy for many people. This study examined 40 Thai employees and 17 foreign customers from three hotels and three tour agencies in Trang, Thailand. The data for this study were collected through a questionnaire from 40 Thai employees. 17 foreign customers answered two open-ended questions, and then the interview was asked. The participants answered about problems and solutions in speaking English. The finding of this study showed that most employees and foreign customers had more verbal communication than non-verbal communication. However, they used several solutions to solve those problems based on their perspectives and experiences.


The interaction between solitons, propagating in a magnetic chain, with a qubit is studied. The spin chain is described by the Heisenberg model in a nearest-neighbour approximation with anisotropy. The quantum bit (qubit) is modeled by a two level quantum system. The equation for the evolution of the qubit is obtained. The role of the parameters of the soliton for the quantum bit dynamics is investigated. The results are analyzed using a geometrical representation for the qubit as a Bloch sphere.


A stochastic partial differential equation-based model has been derived based on the law of mass conservation and the Langevin equation of particle displacement to simulate suspended sediment transport in open-channel flows. In this model, the movement of any suspended sediment particle in turbulent flows is modeled as a stochastic diffusion process, which is composed of a drift term and a random term. The stochastic formula of fluid velocity is then substituted into the advection-diffusion (AD) equation to obtain the stochastic partial differential equation (SPDE) for suspended sediment transport. The lattice approximation is applied to solve the SPDE of suspended sediment transport in open channel flow. The proposed model, explicitly expressing the randomness of sediment concentration, has the advantage of capturing any randomly selected scenarios of particle movement and thus a more comprehensive quantitative description of sediment concentrations compared with the deterministic AD equation. As a result, the probability distribution of the sediment transport rate can be characterized based on a number of realizations obtained in the numerical experiments. It is found from the numerical experiments of particle trajectory that the transport of sediment particles is in the form of fully suspended load when the Rouse number is less than one. The ensemble mean sediment concentration of the proposed SPDE, obtained by the Monte Carlo simulation, agrees well with that of the deterministic AD equation.


The effects of high field viscosity and of low inter-facial tension on the terminal velocity of single liquid drops falling through stationary liquid fields were investigated. Drops of tetrachloroethylene, ranging from 0.08 cm. to 1.4 cm. equivalent diameter, were allowed to fall through four different types of field fluids made by the addition of carboxy methyl cellulose, Lytron 890, corn syrup, and glycerine to water. Viscosities varied from 41.3 to 514 centipoises.

Low interfacial tension systems were ethylchloroacetate-water, furfural-water, and benzyl alcohol-water with interfacial tensions of 16.43, 5.70, and 4.25 dynes per cm. respectively.

For systems of high field viscosity, the usual drag curve appears to be more useful than the correlation proposed by Hu and Kintner. For systems of low interfacial tension (below 20 dynes/cm.) and low field viscosity (of the order of one centipoise) the latter serves to correlate accurately the data of 25 systems.

A comparison of the pour technique with the usual nozzle method for the introduction of drops resulted in a terminal velocity difference of less than three percent. Wall proximity corrections were made when necessary.


Objective To study the effects of aloe gel juice on the scald wound repairing of Taihu pig.Methods In five Taihu-pigs backside skin was scalded separately by self-made scald machine,the superficial Ⅱ° burn wound model was established by 10 seconds scaling and the deep Ⅱ° burn wound model was established by 15 seconds scaling.All the models were divided into 2 groups;in the experimental group the pigs were treated by aloe gel juice and in the control group were not.Pathology investigation was conducted to observe the difference several days later.Results The superficial Ⅱ° burn wound models in the experimental group were recovered without any scar 25 d later while in the control group the pigs were recovered 28 d later.Thirty-four days after burn the most pigs in the experimental group of deep Ⅱ° crusts were off,to 38 d in all experimental groups of deep Ⅱ° burn scabs were completely off,leaving visible scars on the skin surface,but in the control group,three scabs not fully off.The eschar decrustation of the deep Ⅱ° burn wound models were observed,in the experimental group weak scar happened 45 d later;in the control group it showed that convexo-concave eschar existed with white scar meanwhile.Conclusion Aloe gel juice shows the effect of sterilization,cell proliferation promotion and skin structure's recovery.Compared to the control group,it shows less recovery time,better recovery effect,and weaker scar left.


The object of this paper is to clarify the quantification of the tactile effect of building materials from the physical one.Sensation and perception were interpreted on the basis of psychology and physiology. The concept of psychophysio-dynamics was proposed connecting psychophysics with psychodynamics. It was found that the tactile effect of building materials can be pridicted from the physical values of warmth, hardness and roughness. The applicability was verified.


Since World War II,there has been an upsurge of studying political development in the West along with the extensive appearance of newly-sprung countries.Nevertheless,due to the deviation in their understanding,the theories of political development put forward already fail to supply an effective guidance for the political development of the developing countries.By considering the predicaments of this development in those countries and reviewing the state construction of European countries carried out since modern times,scholars have realized the great significance of state construction to the developing countries.Only by means of effective state construction can developing countries get rid of their backwardness and achieve their development.

Abstract Cerebral infarction after coronary artery bypass grafting (CABG) is a serious complication and a problem that remains unsolved. We will report the onset of cerebral infarction in CABG patients in our institution, and its cause, preventive method. The subjects of this research were 761 patients who underwent on-pump isolated CABG. Preoperative, intraoperative and postoperative factors, onset of cerebral infarction and atrial fibrillation were investigated. Postoperative cerebral infarction and postoperative atrial fibrillation were recognized in 1.4% and 24% of the patients, respectively. The risk factors for cerebral infarction were carotid artery stenosis, cardiopulmonary bypass time g180 min, postoperative atrial fibrillation, and β-blocker non-use. The risk factors for postoperative atrial fibrillation were 75 or higher years of age, chronic kidney diseases, emergency surgery, cardiopulmonary bypass time g180 min, intraoperative carperitide non-use, intraoperative landiolol hydrochloride non-use, preoperative angiotensin II receptor blockers (ARB) non-use, preoperative calcium antagonist use, preoperative statin use, postoperative β-blocker non-use, and postoperative aldosterone blocker non-use. The results of this study showed that cerebral infarction occurs frequently in patients who have developed atrial fibrillation, and it was considered that perioperative cerebral infarction can be prevented by perioperative β-blocker, carperitide, anticoagulation therapy and adequate extracorporeal circulation. Since preoperative, intraoperative and postoperative drug use is closely involved in the risk factor for postoperative atrial fibrillation, it was considered possible that adequate perioperative drug therapy can prevent atrial fibrillation and onset of cerebral infarction.

Currently, the implementation of autonomous vehicles remains a major challenge. In this context, the integration of a deep reinforcement learning (DRL) algorithm in an AV has been proposed for navigation in rough and uneven terrain found in rural areas of Ecuador that often lack adequate road infrastructure for vehicular traffic and are prone to considerable damage in case of natural disasters. In order to address these challenges, the autonomous driving system has been implemented in simulation using AirSim that allows emulating some environmental conditions present in these mentioned areas and its performance has been verified through testing. The integration of DRL in AV navigation represents an innovative and effective solution to overcome vehicle mobility limitations and terrain characteristics. In addition, this work has a significant impact on improving efficiency and safety in search and rescue tasks in rural areas of Ecuador, particularly in case of natural disasters.


The standard therapy for obstructive sleep apnoea (OSA) is continuous positive airway pressure (CPAP) therapy. However, long‐term adherence remains at ~50% despite improvements in behavioural and educational interventions. Based on prior work, we explored whether regularity of breathing during wakefulness might be a physiologic predictor of CPAP adherence.


42 The mitral valve is a complex anatomical structure, whose shape is key to several traits of its 43 function and disease, being crucial for the success of surgical repair and implantation of 44 medical devices. The aim of this study was to develop a parametric, scalable, and clinically 45 useful model of the mitral valve, enabling the biomechanical evaluation of mitral repair 46 techniques through finite element simulations. 47 MATLAB was used to parameterize the valve: the annular boundary was sampled from a 48 porcine mitral valve mesh model and landmark points and relevant boundaries were selected 49 for the parameterization of leaflets using polynomial fitting. Several geometric parameters 50 describing the annulus, leaflet shape and papillary muscle position were implemented and 51 used to scale the model according to patient dimensions. The developed model, available as a 52 toolbox, allows for the generation of a population of models using patient-specific 53 dimensions obtained from medical imaging or averaged dimensions evaluated from empirical 54 equations based on the Golden Proportion. 55 The average model developed using this framework accurately represents mitral valve 56 shapes, associated with relative errors reaching less than 10% for annular and leaflet length 57 dimensions, and less than 24% in comparison with clinical data. Moreover, model generation 58 takes less than 5 minutes of computing time, and the toolbox can account for individual 59 morphological variations and be employed to evaluate mitral valve biomechanics; following 60 further development and validation, it will aid clinicians when choosing the best patient-61 specific clinical intervention and improve the design process of new medical devices. 62


The D" layer is one of Earth's most heterogeneous location, hosting poorly understood features, which are most likely linked to the global dynamics of the mantle. Present days tomographic approaches cannot resolve correctly this area. The resolution of images from Earth's inner structure is strongly linked to precisely localizing earthquakes, and to have a good knowlegde of the frequency content of seismic waves. This thesis aims at building a global database of seismic travel times, data used for the development of tomographic images. Our method uses a more precise determination of the depths of earthquakes, allowing an improvement in measuring travel times. To a better evaluation of the frequency content, these measurements are performed in several frequency bands. A new approach for the computation of corrections to the complexity of the crust is presented as well. Finally, a preliminary imaging is presented, at regional and global scale, under the approximation of the ray theory, before a more complete description under Born approximation.


We present a method that partitions a single image into two layers, requiring that one layer has similar properties in terms of pixel colour variation to a provided template patch. First, the paper provides a new view on dening a similarity function for a pixel with its small neighbourhood to be part of the texture described by the template patch. This results in better description of pixels near the texture boundary. Second, it is shown how the Maximally Stable Extremal Regions (MSERs), originally designed for wide baseline stereo matching, can be used to locally merge pixels having the same intensity and thus reduce the dimension of the graph representing the image. The MSERs help in texture description and yield signicant reduction of memory and computation time. Finally the graph is fed into the min.cut/max.o w algorithm to cut the graph into two parts. Performance of the method is presented on some images from the Berkeley database. Finally, restrictions in using the method are discussed.

Purpose – A wealth of research on autism spectrum disorders (ASD) and attention-deficit hyperactivity disorder (ADHD) has led to increased understanding and identification of each of these developmental disorders. Existing literature has sparked controversial discussions regarding whether aspects of ASD and ADHD predispose individuals to criminality. The purpose of this paper is to explore the link between these conditions and offending. Design/methodology/approach – A review of the literature on ASD, ADHD and offending was undertaken. This paper looks at the particular focus of the literature on the involvement of individuals with ADHD and ASD within the criminal justice system. Findings – There is some evidence of a link between ADHD and criminality. However, the relationship between ASD and offending is a little more difficult to ascertain. Complicating this further is the relatively unexplored subject of comorbid ASD/ADHD and criminal behaviour. This paper found that additional cognitive deficits and ...

This research investigates the role of housing in the national economy of Nigeria. The multiple roles of housing in the economy are first ir-vestigcted from a theoretical perspective and then from actual case studies of the construction and housing sectors. A review of Nigerian housing expenditures, labor input to housing and capital formation trends show that housing policy can be made more effective in national development and reach more low-income families than it currently does. This re~aarch concludes that there are two major policy components that can address the housing affordability problem in Nigeria. One group of policies affects the organizational framework. Housing prices can be reduced by the appropriate choice of standards, better urban land management, improved efficiency in the building sector, and assistance to icformal sector hous;.n.g. A second group of policies can increase affordability through housing finance.

Using a large sample of unsolicited takeover attempts, we examine the determinants and effects of targets' choice to adopt poison pills either before or after unsolicited offers and to initiate defensive payouts. The probability of poison pill adoptions decreases with insider ownership, whereas the probability of defensive repurchases increases at a decreasing rate with insider ownership. Poison pills contribute to bid increases and higher bids, yet do not alter the likelihood of takeover. Defensive share repurchases slightly reduce the takeover likelihood but do not appear to harm shareholders, perhaps because they tend to fend off lowball bids or increase the firm's leverage.

about internal defects within the insulation. The index k is defined as the proportionality constant between the changes at high voltage of capacitance ∆C and of the dissipation factor ∆tanδ . ∆C and ∆tanδ values were highly correlated when small flat defects were within the insulation and that correlation was lost in the presence of large narrow defects like electrical treeing. The discrimination between small and large defects is made resorting to partial discharge PD phase angle analysis. For the validation of the results, C and tanδ measurements were carried out in a 15MVA 4160V steam turbine turbogenerator placed in a sugar mill. In addition, laboratory test results obtained by other authors were analyzed jointly. In such laboratory tests, model coil bars subjected to thermal cycling resulted highly degraded and ∆C and ∆tanδ values were not correlated. Thus, the index k could not be calculated.
