In coherent of an implementation of Common European Framework Research (CEFR) to enhance the English proficiency among the graduates, this study investigates one of the alternatives that can be applied by the language teachers to help the students especially low level groups to improve their English proficiency, namely Corrective Feedback (CF). The types and timing of CF used in the higher education language classrooms are investigated simultaneously. The types of CF (explicit and implicit) and timing of CF (online and offline) was the central focus of this study and four language teachers were observed. In order to discover the real practice of language instructors in their language classrooms, 16 hours of class observations was done. It was found out that even the language teachers frequently used explicit correction and recast in providing CF, they also tend to vary their types of CF to the students. It showed that they were all aware of the using types of CF in their language classrooms; however, most of them chose not to correct all their students' oral errors. In terms of the timing of CF, Offline CF or delayed feedback was the preference timing used by the teachers. This finding indicated that the oral CF also tends to receive offline timing. All in all, the findings of this study is important to be understood by the language teachers to enlighten them on the importance of CF as the platform to supply feedback to the low level graduates (A1 to A2 level) to improve their proficiency for the sake of L2 development.

The role of phospholipases in cellular activation and arachidonic acid production for prostaglandin and leukotriene biosynthesis is reviewed. Particular emphasis is placed on the function of phospholipase A2 in the processes. The experimental basis of our current state of knowledge of the mechanism of action of the pure, extracellular phospholipase A2 is considered in detail. Experimental approaches dealing with lipid activation, surface dilution kinetics, and enzyme aggregation are considered, and the "dual phospholipid model" for phospholipase A2 action at the lipid/water interface is described in detail. The kinetic analysis of phospholipase A2 inhibitors, including p‐bromophenacylbromide, manoalide, and an alkylether amide analogue of phosphatidylcholine, is considered in light of this model.

Abstract. This study aimed to investigate whether and how avoidant personality disorder symptoms are related to cardiovascular reactivity to stress tasks with different levels of cognitive demands. The revised Chinese edition of the avoidant personality disorder subscale of Personality Diagnosed Questionnaire-4+ (PDQ-4+) was administered to 222 undergraduate students randomly assigned to psychological stress tasks (i.e., mental arithmetic tasks) with low, moderate, or high cognitive demands (manipulated by task difficulty), during which their physiological data were continuously collected. Results showed that avoidant personality disorder symptoms and cognitive demands of tasks interactively predicted systolic blood pressure (SBP) and diastolic blood pressure (DBP) reactivity. In specific, avoidant personality disorder symptoms were not associated with SBP reactivity under the low- and moderate-demand conditions and DBP reactivity under the low-demand condition but were associated with blunted SBP reactivity under the high-demand condition and blunted DBP reactivity under the moderate- and high-demand conditions. These findings indicate that the association between avoidant personality disorder symptoms and cardiovascular reactivity to psychological stress is contingent on the cognitive demands of tasks, which have potential implications for physical health.


Small and medium companies play an important role in the economic development of any country. This study aims to explore the determinants of capital structure in small and medium companies in Indonesia. The company's capital structure will be influenced by microeconomic and macroeconomic conditions. Purposive sampling conducted in this study generated 15 samples. Data panel analysis was used to analyze small and medium companies in the listed period of 2011-2016. Results of the analysis show that size and profit positively affect the company's capital structure, while other variables do not show significant effects. In average, the small and medium companies in Indonesia have conservative capital structures and positive profits. It is good for the companies to keep their capital structure to stay at a conservative level and continue to improve the company's profitability.


Rapid developments in multi-media technology allow us to innovate our teaching methods by incorporating visualization and simulation tools into conventional, textbook-oriented verbal and pictorial explanations. This project aims to provide students with an in-depth concept enabling an easy understanding of important topics within the discipline of Materials Science and Engineering. By participating in several simulation steps, students will learn the mechanical responses and fracture behavior of advanced materials when subjected to practical loading conditions in various service environments. In this work, 10 topics have been selected from two undergraduates courses where seven animations and four experimental demonstrations are produced, such as toughening mechanisms in semi-crystalline materials, crystal structures, fatigue-crack growth with plastic deformation behavior in metals, etc. Through an internet-based platform, lecturers on the one hand can enhance their presentations by using these animations and demonstrations; on the other hand, students can freely access and review the teaching materials. The anticipated outcome of this project will be tremendously useful to all other related courses in mechanical engineering.


Although abortion is illegal in every Latin American country except Cuba induced abortion is being widely practiced throughout the region. Health planners need reasonable estimates of the prevalence of this practice. A methodology is provided for estimating the numbers of illegal abortions being performed based primarily on the numbers of abortion complications treated in hospitals. Estimates of the number of induced abortions and the ratio of abortions to births for Peru Brazil and Colombia indicate that for every 10 women giving birth 3-4 in Colombia and Brazil and two in Peru terminate their pregnancies.

In this paper, we use Unit Root Test, VAR model and Impulse Responses to examine the relationship between monthly return of S&P500 Index, investment grade bonds, high yield bonds, government bonds, and CPI. By leveraging AIC, BIC, and HQC method, we choose the best lag period. Then we divide whole sample interval into "Rate-Hike Period" and "Rate-Cut Period" to see how they affect each other. In the full time interval, we find when stock market fell two periods ago, current investment grade bond market would surge. Besides, the situation is the same when it comes to high yield bond market. This implies bond market might me overreacted sometimes. In terms of "Rate-Cut Period," we might find overheated economy by examining either investment grade bond market or government bond market. In addition to that, in this time frame we also find that each sub-markets of bond markets interact with each other. When it comes to "Rate-Hike Period," we find that the importance of CPI increase largely. That is, how CPI influences other markets is stronger in this period than other period.

ABSTRACT Tailor-rolled blank thin-walled (TRB-TH) structures have become important vehicle components owing to their advantages of light weight and crashworthiness. The purpose of this article is to provide an efficient lightweight design for improving the energy-absorbing capability of TRB-TH structures under dynamic loading. A finite element (FE) model for TRB-TH structures is established and validated by performing a dynamic axial crash test. Different material properties for individual parts with different thicknesses are considered in the FE model. Then, a multi-objective crashworthiness design of the TRB-TH structure is constructed based on the -support vector regression (-SVR) technique and non-dominated sorting genetic algorithm-II. The key parameters (C, and σ) are optimized to further improve the predictive accuracy of -SVR under limited sample points. Finally, the technique for order preference by similarity to the ideal solution method is used to rank the solutions in Pareto-optimal frontiers and find the best compromise optima. The results demonstrate that the light weight and crashworthiness performance of the optimized TRB-TH structures are superior to their uniform thickness counterparts. The proposed approach provides useful guidance for designing TRB-TH energy absorbers for vehicle bodies.


The term Ummah designates the Islamic holy community, i. e., the religious community. This, the major meaning of the term, is found in the Qur'an but only in a limited number of instances. Although students of Islam have long recognized that the idea of the Ummah and its historical existence have been central to Islamic religiosity, the basic nature of the Islamic holy community has not been adequately elucidated. A proper understanding of the Ummah is critical to any explanation of the religious significance of Islamic law (Shari'ah). Students of Islam know that the term ummah does not always mean "the religious community," but also has several other implications in the Qur'an. Whether the major meaning of the term ummah, as "the religious community," is internally and coherently related to other uses of the term within the Qur'an must be examined. A coherent reconstruction of the relationship among the major meaning and other instances of the term ummah in Qur'anic contexts would do much to elucidate the nature of the Ummah as the Islamic holy community. With this working hypothesis, and setting aside for a while the major meaning, the Qur'anic examples of the term ummah will be analyzed and examined.


[Objective]To compare haemodynamic changes in patients during conventional carbon dioxide pneumoperitoneum laparoscopic cholecystectomy(CLC) and gasless laparoscopic cholecystectomy (GLC). [Methods] Eighty four patients with cholecystolithiasis with ASA Ⅰ~Ⅱ were randomly divided into CLC group (n=42) and GLC group (n=42). Haemodynamic changes were determined by transesophageal echocardiography before (T0) and 10 and 30 min (T2, T3) after pneumoperitoneum or abdominal wall traction, and 10min after desufflation or release of abdominal wall traction (T4) in supine position. [Results]In CLC group, mean arterial pressure(MAP), central venous pressure(CVP) and left ventricular end-systolic volume were significantly higher, and cardiac output(CO), left ventricular ejection fraction(LVEF) and cardiac index(CI) were significantly lower at the stage of T2 and T3. There was no significant difference in haemodynamic changes in GLC group over time. [Conclusion] Carbon dioxide pneumoperitoneum can cause a significant impairment in cardiovascular function. In high-risk patients, gasless laparoscopy may be preferred for its reliability and absence of haemodynamic alterations.


The leading idea of China's reform is Marxism not Neoliberalism.The goal of China's economic system reform is to set up social market economy,while Neoliveralism's core is the market economy based on private ownership.The economic system that we want to set up is to promote market basic function under macroscopic readjustment and control,but Neoliberalism is against macroscopic readjustment and control and for market economy.The diverage between Marxism and Neoliberalism is the difference between historical idealism and historical materialism.

This paper describes an interaction model that allows a user to interact with a computer system through gestures while using gestures at the same time for interaction in the real world. This model uses simple rules for detecting the user's intention to address a gestural command to the system. Some rules are embedded in the model, while others are part of a set of guidelines for designing gestural command sets. Using this model, we have designed an application that allows a user to give a lecture by navigating through a set of slides with gestural commands. From the results of a usability testing of this application, we present other potential applications and directions for future work. This research aims at providing usable applications of hand gesture input in the real world. The results presented in this paper are of interest to researchers working on new interaction techniques based on gestures as well as designers of actual systems.

The nature and thelirnitsof validity of Darcy's law as app[ied to the jYow of natural gas through reservoirs has been considered in order to resolve some controversial aspects of the effect of turbulence on pressure drops. The equivalence between various concepts and viewpoints advanced in the past by several investigators to explain how and why a gas well does not necessarily perform uccording to Darcy*s haw isshowfi. Starting with generalized equations of fiow of ftuhis through porous media,. a partial difleretitial equation has been derived which accurately represents the &w at al! rates. This equation has been numerically solved using on IBM. 704 digital computer. The results permit plots of unsteady radial pressure distribution curves from which specific isochronal backpressure curves may be constructed. These back-pressure curves show the effect of the ~ factor on the slope of the back-pressure curve, The calculations jurther indicate that the drainage rtidius for a gas we!l in turbulent flow propagates at a rate dependent upon the rate of production at the wellbore, This is quite diflerent from the case with liquid flow or naturalgas @w in laminar regime. Addidomdly, the efiect of reservoir inhomogetteities and crossfibw between layers of, different permeability on the back-pressure performance of gas wells has been considered. In light of the current numerical results the significance and limitation O! the rate of flow function Y proposed by Smith" has been discussed.


The purpose of this study is to determine the relationships between structural and psychological empowerment of teachers and their organizational citizenship behaviors. The sample of this descriptive study consists of 384 teachers employed in the province of Mugla. The data of the study were collected through the administration of the questionnaires (namely Conditions of Work Effectiveness Questionnaire, Psychological Empowerment Scale and Organizational Citizenship Behavior Scale) to the teachers in the sample. In the analysis of the data, descriptive statistics, t test, ANOVA and hierarchical multiple regression analysis were conducted. The study revealed that that the level of teachers' organizational citizenship behaviors (OCB) is higher than the medium level. Besides, teachers' organizational citizenship behaviors differed significantly in terms of the variables of gender, school type and school location (urban or rural) whereas there was no significant difference in terms of the variable of seniority. The level of teachers' structural empowerment (SE) was determined to be medium. Moreover, in terms of school type and school location variables, some dimensions of teachers' SE differed significantly, however no significant difference was found in terms of gender and seniority variables. On the other hand, the level of teachers' psychological empowerment (PE) was high. In terms of gender and school type variables, some dimensions of teachers' (PE) differed significantly, yet it did not differ significantly according to the variables of seniority and school location. In addition, teachers' psychological and SE explained one third of the OCB. According to the results of regression analysis, both the dimensions of knowledge and opportunity and the dimension of individual oriented empowerment were identified to be significant predictors of OCB. In addition, some recommendations were developed in the study in order to increase teachers' structural and psychological empowerment.

We introduce a concept of the Mach–Zehnder–Fano interferometer by inserting a cavity exhibiting Fano resonance into a conventional interferometer. By employing the scattering-matrix approach, we demonstrate that the transmission becomes sensitive to a position of the cavity such that an asymmetric structure exhibits a series of narrow resonances with almost perfect reflection. We discuss how to implement this novel geometry in two-dimensional photonic crystals and use direct numerical simulations to demonstrate novel regimes of the resonant transmission and reflection.

Introduction Despite the fact that 95% of all <5 years of age children with developmental disabilities including Autism Spectrum Disorders (ASD) live in low- and middle-income countries (LAMI), to date there is an information gap in LAMI studies including Republic of Georgia. Objectives To estimate the prevalence and describe the clinical characteristics of ASDs among the third-grade school students using a total population approach. Methods The target population (N=27,336) included all 3rd grade students of schools of five main cities of Georgia. The study was conducted in four steps: phase I screening, sampling of screen positive students, phase II confirmative diagnostic assessment, and best-estimate diagnosis. Parents and teachers completed two screening questionnaires in phase I: 27-item Autism Spectrum Screening Questionnaire (ASSQ) and 25-item Strengths and Difficulties Questionnaire (SDQ). In phase II, screen-positive children were evaluated using standardized diagnostic assessments. Results Overall, 16,654 students (82%) were assessed by either parent and/or teacher. Students whose ASSQ and/or SDQ scores were in the top 10th percentile were considered as screened positive for diagnostic assessment (N=1976). Of 300 students completed diagnostic assessment 53 were diagnosed ASD. Crude prevalence of ASDs was estimated to be 4.5%. 75% of cases of ASD were first diagnosed. Efforts are currently underway to compute adjusted prevalence, which will be available for the Conference presentation. Conclusions The prevalence data of ASD is important to assess the burden of the disorder and facilitate better understanding of specifics of the disorder in different part of the world. Disclosure No significant relationships.

Airway management in retrosternal goitre with documented tracheal compression can pose several difficulties. Currently awake fibreoptic bronchoscope guided intubation seems to be the standard airway management option. But sometimes even this option can have its own flaws which calls for alternative options. Here we suggest an alternative approach to such an anticipated difficult airway.


Purpose To compare early-stage intrableb structural changes after Ex-PRESS surgery using anterior-segment optical coherence tomography between primary open-angle glaucoma (POAG) and exfoliation glaucoma (XFG). Methods Twenty-five POAG eyes and 15 XFG eyes that underwent Ex-PRESS surgery were evaluated. Intrableb images were classified into four categories based on previously reported scattering intensity: high-, medium-, and low-scattering walls and fluid-filled spaces. Bleb measurements were evaluated in both groups throughout 6 postoperative months. The 3-year surgical success was defined by the criteria intraocular pressure (IOP) < 18 mmHg and IOP < 15 mmHg with or without medications. Results The fluid-filled space volume at 3 and 6 months (P = 0.005 and P = 0.022, respectively) and the volume ratio of the low-scattering wall to the bleb wall (P = 0.028) at 6 months were significantly smaller in XFG than POAG postoperatively. The volume ratio of the high-scattering wall to the bleb wall was correlated positively (P = 0.007) with the IOP, and that of the low-scattering wall to the bleb wall was correlated negatively (P = 0.002) with the IOP in XFG. The 3-year surgical success rates for both criteria were significantly lower in XFG than POAG. Conclusions Fluid-filled spaces were smaller in XFG than in POAG after Ex-PRESS surgery. The proportion of the high-scattering wall tended to increase and the low-scattering wall tended to decrease in XFG eyes with high IOP. Early-stage intrableb structural changes differed between POAG and XFG and may affect the prognosis. Translational Relevance Our cutting-edge observation of intrableb fibrosis can be an important predictor of the surgical outcome.


Experiment was conducted at Sugarcane research Station, Sirugamani during 2002-2003 under irrigated condition to study integrated nutrient management on growth, yield and quality of sugarcane var. Co.Si. 95071. The experiment was conducted in randomized block design with three replications. The gross plot size was 5 m x 4 m. The treatment includes three levels of nitrogen and phosphorous, sources of phosphorus and along with and without intercropping and incorporation of daincha on 45 DAS and soil application of biofertilizers (azosprillum + phosphobacterium). Application of recommended dose of 100% N and 100% P as Missouri rock phosphate with biofertilizers (Azospirillium and phosphobacterium) each @ 10 kg per ha as soil application and incorporation of daincha intercrop on 45 DAS recorded maximum CCS%, cane yield and sugar yield of 13.9%, 144 and 20.1 tonnes per ha respectively. The increase in cane yield and sugar yield over recommended 100% N and 100% P 2 O 5 per ha were associated with growth and quality parameters. The data revealed that there could be a saving of 25% N and 25% P 2 O 5 with the application of biofertilizer viz., azospirillium and phosphobacterium as well as intercropping and incorporation of daincha on 45 days after sowing.


A local electrode atom probe is used to characterise a number of binary and commercial nickel-based alloys, specifically to determine whether rhenium atoms form solute clusters in these materials. The data are analysed via a statistical approach and results are compared to simulations which take the typical eciency of the atom probe and the scatter in atomic positions into account. Thus, even the smallest clusters can ‐ in principle ‐ be detected by the algorithm. The analysis demonstrates conclusively that rhenium is not prone to clustering in the nickel lattice above the level associated with the random distribution of Re atoms. A similar conclusion applies to the other 5d elements (Ta, W, Ir and Pt) analysed in this study.


The issues concerning phytosanitary protection of forests generally speaking, and pine forests, particularly are in attention of scientists, in the field, worldwide. For this reason more concern is attribute to the regulations meant to rule the use of phytosanitary products used for maintaining the health of pine forests, and methodology of their administration. Our study aims to emphasize the degree of perception of aimed authorities, concerning the phytosanitary regulations connected to pine forest phytosanitary products. The methodology developed in this study concerns the means of sociological means, translated in bibliographical approach which involves the use of different documents, law texts, textbooks, and also the questionnaire instrument. As a result of our approach we highlight the most important issues meant to contribute to better protection of pine tree forests through an appropriate phytosanitary treatment, and also the most important issues concerning pine tree forests maintaining focused by the actors involved in their maintaining. The phytosanitary regulations play a decisive role in maintaining the health of forests, generally speaking and of pine tree forests, in particularly. They supply a general frame for appropriate treatments for suitable forest development.


In this work the design and optimization of a DC/DC half-bridge converter with a coreless PCB transformer and high insulation voltage is presented. The analysis starts by computing coreless transformer magnetic parameters (i.e. auto and mutual inductance of the coils) through a simple Matlab/sup /spl reg// function. The procedure is applicable to both circular and rectangular spiral coils. These results were used to model the half bridge converter, and obtain the output V-I characteristic and the maximum output power. Detailed experimental results on a 4 W laboratory prototype confirmed theoretical predictions.


As part of a TRU waste-sampling program, Los Alamos National Laboratory retrieved and examined 44 drums of /sup 238/Pu- and /sup 239/Pu-contaminated waste. The drums ranged in age from 8 months to 9 years. The majority of drums were tested for pressure, and gas samples withdrawn from the drums were analyzed by a mass spectrometer. Real-time radiography and visual examination were used to determine both void volumes and waste content. Drum walls were measured for deterioration, and selected drum contents were reassayed for comparison with original assays and WIPP criteria. Each drum tested at atmospheric pressure. Mass spectrometry revealed no problem with /sup 239/Pu-contaminated waste, but three 8-month-old drums of /sup 238/Pu-contaminated waste contained a potentially hazardous gas mixture. Void volumes fell within the 81 to 97% range. Measurements of drum walls showed no significant corrosion or deterioration. All reassayed contents were within WIPP waste acceptance criteria. Five of the drums opened and examined (15%) could not be certified as packaged. Three contained free liquids, one had corrosive materials, and one had too much unstabilized particulate. Eleven drums had the wrong (or not the most appropriate) waste code. In many cases, disposal volumes had been inefficiently used. 2 refs., 23more » figs., 7 tabs.« less


This article explores the activities of the United States Committee for the Care of European Children (USCOM), a non-sectarian rescue organization that operated throughout World War II. USCOM managed to bring to the US a total of approximately 1,300 children—both Jewish and non-Jewish—in two separate operations: the first from Britain in 1940, and the second from concentration camps in southern France between 1941 and 1944. In its effort to find suitable host families for the children in the United States, the committee cooperated mainly with Jewish organizations.

Since studies on privacy-preserving database outsourcing have been spotlighted in a cloud computing, databases need to be encrypted before being outsourced to the cloud. Therefore, a couple of privacy-preserving kNN query processing techniques have been proposed over the encrypted database. However, the existing schemes are either insecure or inefficient. Therefore, in this paper we propose a secure and efficient kNN query processing algorithm. Our algorithm preserves both data privacy and query privacy while hiding data access patterns. To achieve a high efficiency in query processing, we also propose efficient and secure protocols using Yao's garbled circuit and a data packing technique. Through our performance analysis, we verify that our proposed scheme outperforms the existing schemes in terms of a query processing cost.


In an experimental study process-oriented and result-oriented feedback was offered in the educational serious game "Zeldenrust". The central research question was; what is the effect of process-oriented feedback and result-oriented feedback on perseverance and response to a failure experience in a mathematics serious game. The learning content consisted of proportional reasoning, which asked some effort of these pupils. 171 students, between 10 and 14 years, from three different schools, took part. The data was collected through logfiles, obtained by playing the serious game.
No differences were found between feedback conditions in game behavior (i.e. time on task, number of correct answers, number of attempts) and the degree of perseverance. A regression analysis showed that students who Received Process-oriented feedback seemed to rely more on their prior knowledge of proportional reasoning which eliminated some of the effects of a frustrating minigame. This was particularly true for lower-performing students. From this data can be carefully concluded that Process-oriented feedback has an effect on how students respond to a failure experience.


Introduction: The calcaneum is repeatedly subjected to static and dynamic stresses especially in the weight-bearing positions during walking, working or running and this is reflected in the trabecular pattern within the calcaneus. There are six radiological angles associated with this bone notably the Böhler (tuber joint) angle (BA) and Gissane's angle (GA), and they vary in different ethnic population. Aim: This is to determine the calcaneal angles among the ethnic Igbos of South Eastern Nigeria, determine the relationships between these angles, determine any correlation with gender and age, compare the values of the BA and GA to that of other populations and discuss the clinical implications of the determined values. Methodology: A 5-year review of all lateral views of X-rays of the foot and ankle done at Federal Teaching Hospitals, Abakaliki, Nigeria, from 1st January 2012 to 31st December 2016, was done. Drawing and mathematical sets were used to measure the six radiological angles on the lateral views of plain X-ray films of the ankle and subjected them to descriptive and inferential statistics. Results: There were 120 patients, 65 males and 55 females. The calcaneal angles among the ethnic Igbos of South Eastern Nigeria showed the following: BA: 32.58 ± 4.98, GA: 121.22 ± 6.11, calcaneal compression angle: 30.00 ± 3.01, talocalcaneal angle (TCA): 22.58 ± 5.28, calcaneal pitch angle: 17.35 ± 3.79 and apical angle (AA): 67.24 ± 7.27. There was no relationship between these angles. The TCA and AA showed a correlation with gender and age and other angles did not. There was a statistically significant difference between BA values in this study and that of Ugandan and American populations (P < 0.05). There was a statistically significant difference between the GA values in this study and that of Turkish, New Zealand and Indian populations. Conclusion: These determined values would be a useful tool in the management of patients of Igbo extraction with of the foot pathology.

The development of a constitutive model for anisotropically consolidated clay is described. The model, based on critical state soil mechanics concepts, has a rotational hardening non- associated flow rule. To assess the model, data from stress path triaxial tests conducted as part of the research programme and reported in the literature have been predicted. This has resulted in good correlations which significantly improve on predictions using Modified Cam Clay, an isotropic associated model. (A) For the covering abstract see IRRD 859983.


(001) oriented epitaxial Pt bottom electrode was prepared on Si(001) substrate using four fold buffer layer of ST/LSCO/CeO 2 /YSZ. On the epitaxial Pt bottom electrode, we found that both epitaxial and polycrystalline BST thin film can be prepared by the change of oxygen gas flow procedure during heating up to deposition temperature of BST. Without oxygen gas flow on the heating process of the Pt bottom electrode, BST thin film was changed into polycrystalline, on the other hand, when the Pt bottom electrode was heated in 100 mTorr of oxygen pressure, epitaxial grown BST thin film was realized. This means that the orientation of BST thin film can be controlled by the oxygen flow procedure during heating of the Pt bottom electrode. Dielectric constant and tunability of epitaxial BST thin film changed with the oxygen pressure during heating and deposition of BST thin film. This suggests that oxygen pressure during heating and deposition is the key to control the orientation and properties of BST thin film.


Computational fluid dynamics(CFD) numerical simulation is employed on the middle tower caisson of Taizhou Bridge,analyzing its flow-force-induced vibration amplitude and cycle in different flow conditions.The vortex in the back of the caisson causes the vertical constant force and oscillation force and exciting force perpendicular to the flow direction.The volume of two kinds of forces decides the form of the vibration.A larger lift cycle amplitude change appears when 3.5×107≤Re8.1×107.If the caisson is sinking in this Re scope,the anchor cable should be strengthened to prevent shimmy.

Collimators can generally be characterized by their sensitivity distributions. Therefore it appears of advantage to introduce measurement conditions in the characteristic magnitudes adapted for medical uses, which would greatly alleviate the manipulation of collimators. A typical collimator apparatus, consisting of three conical collimators of different apertures as well as of a 9-channel, 19channel and slit-channel collimator, was introduced. The characteristic magnitudes (zero effect, effectivity, resolution, and screening behavior) of the individual types were experimentally determined according to their definition and discussed.

The problem of automating the process of line generalization has been very difficult. It has not been solved yet despite the concerted effort of many private firms as well as government agencies. There does not exist an algorithm which can automatically perform this process when there is a drastic change in scale between the original and generalized maps. In this paper, an algorithm which is successful in automatically generalizing lines from any large scale to any small scale is presented. The algorthm achieves different levels of smoothing the line while preserving the overall shape of the line. The results are compared with those obtained by manual methods. It was found that the results obtained by the algorithm are very close to those obtained by cartographers using manual methods.


Objective To investigate the influence of percutaneous coronary intervention( PCI)on the prognosis of acute coronary syndrome( ACS) in the elderly( age 75 years old). Methods There were 1640 patients with ACS admitted in the cardiology department in our hospital from December 2011 to September 2013. Among the 374 patients with ACS who fulfilled the inclusion criteria were consecutively enrolled in this study. They were divided into two groups: PCI group( 55 /374,14. 71%) and conservative medical treatment group( 319 /374,85. 29%). All the clinical data were collected and regularly followed up. Results There were no statistical significance between the two groups in the sex,co-morbidities of hypertension,diabetes,dyslipidemia,history of smoking and heart failure at admission,all P 0. 05. The history of acute pulmonary edema and cardiogenic shock had no statistical significance between the two groups,P 0. 05. Medlication received by patients in the 2 groups including aspirin,ACEI,ARB,beta blockers and statins showed no differences, P 0. 05. However, more patients were prescribed with clopidogrel in the PCI group than patients in the conservative treatement group,P 0. 05. We found that patients in the PCI group had higher all cause mortality and major adverse cardiovascular events than patients in the conservative treatment group,P 0. 05. In the COX proportional hazard model,cardiogenic shock( HR 8. 00),acute pulmonary edema( HR 4. 61),heart failure history( HR 7. 51) and female( HR 3. 57)were found to be independent risk factors for bad prognosis in ACS patients over 75 years old,all P 0. 05.However,PCI was a protective factor for ACS in the elderly( HR 0. 21,P = 0. 02). Conclusions PCI may reduce the all cause mortality and incidence of major adverse cardiovascular events for the ACS patients over 75 years old,which should be a preferable treatment to improve the long term prognosis of them.


AbstractWhere moderate running speeds and loadings are involved, ball bearings engineered from polymer resins can offer significant advantages over their steel counterparts. They also give a far superior performance than can be obtained from plastics bushes. A primary disadvantage of running a shaft in a plastics bush is that, if unacceptably high friction losses are to be avoided, it has to be a fairly loose fit. In a polymer ball bearing, friction is only about one seventh of that experienced with a comparable bush bearing and the bearings are manufactured to close diametrical tolerances, enabling precision running to be preserved.


Carbon and nitrogen turnover in soils having continuous inputs of litter is described using theory developed for single cohorts of litter. Fresh litter is characterized by its quality (how easily it is decomposed by microbes) and its N:C ratio. The decom- position process is described as a continuum and no transition between litter and humus is recognized. Equations are derived for the amounts of carbon and nitrogen in the soil at steady state. Depending upon the microbial production-to-assimilation ratio when substrate of the lowest quality (most-degraded litter) is decomposed, steady state implies either constant or linearly increasing amounts of soil carbon and nitrogen. Comparisons are made between theoretically estimated and observed relations between soil carbon and nitrogen turnover rates for a large range of terrestrial ecosystems, as well as carbon and nitrogen stocks in a Scots pine forest soil.


The delamination and the fatigue crack propagation behavior in aramid fiber reinforced metal laminates(AFRMLs) containing a saw-cut and circular hole such as the fuselage-wing intersection was investigated. The fatigue crack propagation in aluminum layer is accompanied with the delamination between aluminum layer and fiber layer. The delamination deteriorates the fiber bridging mechanism in the crack tip of AFRMLs. Therefore, this study evaluates the stress distribution of AFRMLs containing a saw-cut and circular hole using the Average Stress Criterion (ASC) model. The delamination zone was observed by ultrasonic C-scan images. As the result of this study, in case of AFRMLs containing a saw-cut specimen. the fatigue crack propagation always occurred in aluminum layer and the delamination zone formed along the fatigue crack. However, in case of AFRMLs containing a circular hole specimen, the delamination zone was formed in two types. First, delamination zone was formed along the fatigue crack in aluminum layer. Second, delamination zone was formed without any fatigue crack around the circular hole. Consequently, delamination zone was formed dependently on the notch shape and the stress distribution.


As teachers of interior design, one of our major responsibilities is to devise projects that develop the skills and perceptions our students need to work effectively in professional situations. Opportunities to enhance skills are easily provided, since almost all projects require drafting, rendering, and layout. Patterns of perception are more indirectly influenced; for example, students may graduate with only a vague understanding of the needs of space-users, or of the designer-client relationship, unless projects are developed which include contact with actual institutional, corporate, and residential clients. Such projects will do much to ease the "culture shock" a young interior designer may feel upon moving from the student to the professional world. The team project is another which may facilitate this passage. Most programs regularly conduct intradisciplinary projects so that students may experience the cooperation and leadership of this approach to design. EQually important is the interdisciplinary (or even cross-disciplinary) project. Increasingly today, problems are approached through the joint efforts of many specialities; and interior designers frequently join with architects, industrial designers, visual designers, landscape architects, lighting consultants, fine artists, businessmen, urban planners, and/or engineers to research and resolve various issues. Pre-professional experience on an interdisciplinary design team will do much to alert the student to the sometimes conflicting philosophies and techniques associated with other disciplines, and prepare him to make a meaningful contribution to such groups. As valuable as interdisciplinary projects may be. however, they can pose problems even for students and faculty familiar with the intradisciplinary approach. It is important that we as interior design educators anticipate the reactions that such projects may engender, and direct our teaching so that our students will derive maximum benefit. To this end, the following report of an interdisciplinary project recently conducted at Purdue University describes both its shortcomings and successes, and attempts to develop a model for future projects.


TNF is important in rheumatoid arthritis (RA) and spondyloarthritis (SpA) pathogenesis. Recently reports showed sTNF levels were significantly lower in SpA than RA synovial fluid (SF). Therefore, the differential regulation of TNF in both diseases were investigated focusing on the balance of sTNF-tmTNF and both TNF receptors expression. Synovial fluid from 22 RA and 25 SpA were analyzed by ELISA. sTNF was confirmed significantly higher in RA than SpA. Total TNF of synovial tissues assessed by qPCR showed similar levels, suggesting a higher tmTNF/sTNF ratio in SpA. The levels of sTNF-R1 and sTNF-R2 were significantly lower in SpA than RA SF. Interestingly, sTNF-R2/sTNF-R1 increased in SpA. qPCR on synovial tissue showed similar mRNA levels for TNF-R2 but decrease of TNF-R1 in SpA. IL-6R levels did not showed differences and TIMP-3 tended to be higher in RA than in SpA SF. In conclusion, we observed a shift from sTNF/TNF-R1 in RA to tmTNF/TNF-R2 in SpA.


Objective To observe the efficacy of trimetazidine for treatment of coronary heart disease-congestive heart failure( CHD-CHF) and effect on plasma brain natriuretic peptide( BNP) level. Methods Eighty-four patients with CHDCHF were selected and then were divided into observation group and control group according to the different treatment,with 42 cases in each group. The patients in control group were given conventional treatment included cardiotonic,diuretic and vasodilator. Based on these,the observation group were treated with trimetazidine. All patients were treated for one month. The comprehensive efficacy of two groups were evaluated,and indexes of cardiac function include left ventricular ejection fraction( LVEF),left ventricular end-diastolic diameter( LVEDD) and 6 minutes walk distance( 6MWD) were observed before and after treatment,as well as the BNP levels were detected before and after treatment. Results The effective rates were 92. 9% and 73. 8% in observation group and control group respectively,the difference was statistically significance( P 0. 05). The difference of LVEF,LVEDD,6MWD and BNP levels between two groups before treatment was not significant( P 0. 05); after treatment,the LVEF and 6MWD increased,the LVEDD and BNP decreased in observation group compared with control group( P 0. 05). Conclusion Trimetazidine has a significant effect for the treatment of CHD-CHF,it can rapidly improve patients' cardiac function,as well as reduce levels of BNP.


Few investigations have looked at behavioral stress outcomes in Alzheimer's caregivers. This study documented concentration deficits to examine behavioral outcomes of stress in 33 Alzheimer's Disease (AD) caregivers and in 33 age-, sex-, and race-matched controls. As hypothesized, caregivers showed less persistence than controls in solving problems from a standard test of problem-solving ability. In addition, caregivers tended to make more errors than controls on a standard proofreading task (p < .09). In AD caregivers, cognitive deficits (represented by lower scores on problem-solving and concentration tasks) may be representative of a broader deficit in concentration that impairs the ability of caregivers to provide for their own needs and the needs of the family member for whom they are caring.


In order to obtain the maximum characteristic intensity of the up-conversion luminescence in GdTaO4:RE/Yb(RE=Tm, Er) series, we established the regression equation between the luminescent intensity of the phosphors and the rare earth doping concentration upon the 980 nm laser excitation based on the experimental optimization design. The Tm3+/Yb3+ doping samples were combined with the uniform design and quadratic general rotation combination design, meanwhile the Er3+/Yb3+ doping samples were optimized by the uniform design and cubic orthogonal phosphor step by step. The relationship between concentration and luminous intensity was analyzed. The results showed that the concentration changes of RE3+ (RE=Tm, Er) and Yb3+ had a significant effect on luminous intensity, and there were extreme points of luminescent intensity in the test space. By solving the regression equation, we gained the optimal doping concentrations. The optimal samples were also prepared by high-temperature solid state method. The XRD diffraction patterns of the optimal samples are analyzed. The results show that the samples are pure phase, the doping of Li+ flux will inhibit the generation of reaction impurity phase, and the doping of rare earth will shift the diffraction peak to a high angle without changing the peak shape. The relationship between excitation power and luminescent intensity is analyzed. The results show that the blue light emission of Tm3+/Yb3+ co-doping phosphor is a three-photon process, and the green light emission of Er3+/Yb3+ co-doping phosphor is a two-photon process. The relationship between sample temperature and luminescent intensity is analyzed. The luminescent intensity of the sample decreases with the increasing of the temperature, indicating temperature quenching. Finally, the quenching activated energy of the sample is calculated.

Traditionally, renewable sources of energy have only been seriously considered for technological growth to achieve II. CIRCUITRY FOR A "GREEN" ART PIECE energy sufficiency. However, there has been a steady increase in harnessing them to showcase value, like decorating building exteriors or artistic structures. At Nanyang Technological University (NTU), we have been exploring a confluence of art and engineering. Such a "renewable powered art piece" is an example of a perfect blend of the work of artists and engineers. In this paper, we present our work for any aesthetic lighting structure for outdoor installations- which drives the "Go Green!" movement for an environmentally conscious Singapore. The proposed design is for any outdoor lighting structure which will be illuminated by LEDs. Key features of the circuitry employed in such a structure include a solar powered LED lighting system with ambient light detection for automatic turn on/off and effects based on wind incident on the art piece/ structure.

A new rigid-rod high performance polymer fiber, called commercially M5, has been developed by Akzo Nobel. The formation of a bi-directional hydrogen bonding network, including intra-molecular one and inter-molecular one, cause an increase in interaction between polymer chains. This 2-D structure results in high strength, high modulus, high compressive strength and good non-flammability of M5 fibers.


The recent advancements of three laser-based diagnostic technologies developed at the Riga group are briefly reviewed: (i) RGB imaging of cw-laser excited skin autofluorescence intensity and photobleaching rate distributions, (ii) ps-laser excited skin autofluorescence and diffuse reflectance kinetics analysis, (iii) snapshot RGB skin chromophore mapping under triple-laser illumination. These techniques have passed preliminary laboratory and clinical tests which have demonstrated a promising potential for further implementation in portable devices for routine clinical applications. Operation principles, set-up schemes and some clinical results obtained by the above-mentioned techniques are discussed in this paper.


The c-Abl protein-tyrosine kinase regulates diverse cellular signaling pathways involved in cell growth, adhesion, and responses to genotoxic stress. Abl is well known in the context of Bcr-Abl, the active fusion tyrosine kinase, which causes chronic myelogenous leukemia (CML) and other leukemias. The tyrosine kinase activity of Abl is tightly regulated by auto-inhibitory interactions involving its non-catalytic SH3 and SH2 domains. Mutations that perturb these intramolecular interactions result in kinase activation. This study examined the effect of activating mutations on the biochemistry and solution structure of Abl core proteins. In an active myristic acid-binding pocket mutant (A356N), the relative positions of the regulatory N-cap, SH3 and SH2 domains were virtually identical to those of the assembled wild-type core despite differences in catalytic activity and thermal stability. In contrast, a dramatic structural rearrangement in an active gatekeeper mutant (T315I) was observed with the positions of the SH2 and SH3 domains reversed relative to wild-type. These results show that Abl kinases can adopt multiple conformations in solution and kinase activation does not necessarily require destabilization of the assembled core structure.
Small molecules that allosterically regulate Abl kinase activity through its non-catalytic domains may represent selective probes of Abl function. I developed a screening assay to identify chemical modulators of Abl kinase activity that either disrupt or stabilize the regulatory interaction of the SH3 domain with the SH2-kinase linker. This fluorescence polarization (FP) assay is based on a recombinant Abl protein containing the regulatory domains (Ncap-SH3-SH2-linker, N32L) and a short fluorescein-labeled probe peptide that binds the SH3 domain. The probe peptide binds the recombinant Abl N32L protein in vitro producing a robust FP signal. Mutation of the SH3 binding site (W118A) or introduction of a high-affinity linker both resulted in loss of the FP signal. Pilot screens were performed with two chemical libraries (2800 compounds total), and thirteen compounds were found to specifically inhibit the FP signal. Secondary assays showed that one of these hit compounds enhances Abl kinase activity in vitro. These results show that screening assays based on the regulatory domains of Abl can identify allosteric modulators of kinase function.


PKI schemes have significantly evolved since X.509, with more complex goals, e.g., transparency, to ensure security against corrupt issuers. However, due to the significant challenges involved and lack of suitable framework, the security properties of PKI schemes have not been rigorously defined or established. This is concerning as PKIs are the basis for security of many critical systems, and security concerns exist, even for well known and deployed PKI schemes, e.g., Certificate Transparency (CT). We present precise definitions allowing provably secure PKI schemes, with properties such as accountability, transparency and non-equivocation. We demonstrate usage of the PKI framework against X.509 version 2.


Aim . Analysis of the over all spectrum of life forms of the flora of coastal ecosystems of Dagestan and structural variability of the spectrum indifferent types of plant communities. Methods . The species composition of plant communities and their structural and dynamic features have been determined according to biomorphological indicators during the research and post-processing of the collected material. Based on system of Raunkiera K. (1934) there have been identified five major biomes (fanerofity, hamefity, hemicryptophytes, cryptophytes, terofity) of the flora of coastal ecosystem sof Dagestan, without any further specification. Results . Hemicryptophytes numbering 437 species or 43.52% of the total species composition have been dominated in the flora of coastal ecosystems of Dagestan. In second place terofity (388 species, or 38.64%), the third cryptophytes (80 species or 7.97%). Fanerofity and hanefite are respectively 6.57% and 3.68%. Thus, herbaceous species account or 905 species, or 90.13%. Trees, bushes and shrubsaccountfor a totalof 103 species, or 9.87%. A fairly large percentage of Trofimov can be explained by participation in the studied flora of weedy annuals. Main conclusions. By dominant, similar to the total spectrum of life forms of flora, the position of hemicryptophytes and Trofimov semi-desert and dry steppe plant communities are zonal and climatically determined for this area.


This study examines the linguistic devices discourse participants use in English teaching radio programs to shift their interactional frame from presenter/listener to presenter/presenter. Frame theories have been widely used to explain the way people organize their knowledge and to understand social interaction, but little research has been done on the ways by which people use to shift frames in social interaction. This study finds that the linguistic devices people use in the discourse include phonological (e.g. high key), lexical (discourse markers such as well, so, but, okay, etc.) and interactional ones (questions). It suggests that discourse participants need to carefully operate frame shifting so that others can align themselves to a proper frame and avoid frame breaking and communication breakdown.


Bread wheat (Triticum aestivum L., AABBDD, 2n = 6x = 42), which accounts for most of the cultivated wheat crop worldwide, is a typical allohexaploid with a genome derived from three diploid wild ancestors. Bread wheat arose and evolved via two sequential allopolyploidization events and was further polished through multiple steps of domestication. Today cultivated allohexaploid bread wheat has numerous advantageous traits, including adaptive plasticity, favorable yield traits, and extended end-use quality, that have enabled its cultivation well beyond the ranges of its tetraploid and diploid progenitors to become a global staple food crop. In the past decade, rapid advances in wheat genomic research have considerably accelerated our understanding of the bases for the shaping of complex agronomic traits in this polyploid crop. Here, we summarize recent advances in characterizing major genetic factors underlying the origin, evolution, and improvement of polyploid wheats. We end with a brief discussion of the future prospects for the design of gene cloning strategies and modern wheat breeding. This article is protected by copyright. All rights reserved.

Objective Twenty-two critical surgical patients were treated by total parenteral nutrition (TPN) or enteral nutrition (EN) and good results were achieved. Among the 22 patients, 10 were suffered from MOD. Methods Nutritional substances and metabolism were investigated. In the earlier stage, low calories, low glucose、 lipid and nitrogen supply were favorable to the critical patients, total calories of PN supplied not more than 20 kcal/kg/d, nitrogen was supplied in 0.15 g/kg/d, with lipid at a rate of 40 percent. After the resolution of stress, increasing the content of glucose、 lipid and nitrogen the total calories and nitrogen given were not more than 25 kcal/kg/d and 0.20 g/kg/d. When gastrointestinal function recovered EN should be instituted. Results By this nutritional support and the surgical treatment, 17 cases were cured and 5 died; during this period, there had not been abnormalities of glucose, fat metabolism and liver function. No serious diarrhoea, vomiting or abdominal distention occurred.Conclusion Nutritional support is most essential to critical surgical patients, parenteral nutrition should be given when the gastrointestinal function is disordered, enteral nutrition should be followed at a later stage to reduce the translocation of gut bacteria and endotoxin and decrease the rate of intestinal infection.(Shanghai Med J, 2000,23∶717-720)


Objective To purify and character the recombinant human coagulation factor Ⅶ (rhFⅦ) from the cells expression supernatant fluid. Methods The monoclonal antibody was coupled with the CNBr-Sepharose 6B Fast Flow media and formed FⅦ immunoaffinity chromatography gel, which was used to prepare the column. The column was validated by using standard recombinant human coagulation factor Ⅶ. Then the rhFⅦ was adsorbed by DEAE-Sephadex A-50 gel from the cells expression supernatant, removed salts by Sephadex G-25 gel column and followed by FⅦ immunoaffinity chromatography column. The total and purify protein were monitored at each stage using SDS-PAGE and Western Blot. The biology activity of purified rhFⅦ was confirmed by prothrombin time (PT) assay. Results The FⅦ immunoaffinity chromatography column showed a good absorption to standard and expressed rhFⅦ protein; non-special proteins were removed after three steps purification; the coagulation time of purified protein was 52s, which indicated the protein was fully biological activity. Conclusion Recombinant human coagulation factor Ⅶ monoclonal antibody immunoaffinity chromatography method was constructed successfully and provided a useful system for future study.

The author has investigated the acclimation processes of the apple cultivars Ascolda and Spartan on nine clonal rootstocks bred in Ukraine. The degree of different tissues frost-resistance has been terminated and the acclimation processes in one - year germinations estimated. The cul- tivar-rootstock combinations have been selected which are the most adapted to the hibernation conditions under the conditions of the Ukraine's northern.


On a hand collected data set of around 1000 US publicly listed targets over the period from 2005 until 2011, this paper shows a counter-intuitive result that a higher number of bidders in takeover contests is associated with a smaller premium. As an explanation for this puzzling relationship, we show that takeover contests with a higher number of bidders are usually those with a high common value component that are easy to replicate. These deals are also associated with smaller bidders' valuations and so smaller value created after the takeover. In contrast, private value contests that depend on a specic t between the acquirer and the target usually attract fewer bidders but at the same time are associated with higher bidders' valuations and higher synergies created. After controlling for this compounding eect, the puzzling negative relationship disappears.


When the National Conference of State Legislatures (Pound 2009) issued its report on the fiscal condition of states in February 2009, few would have guessed how much worse conditions would be by the fall. With national unemployment hovering around 10 percent, trending upward toward 14 percent in some states and nearly 20 percent in some metropolitan areas, it is little wonder that journalists call this the Great Recession. The benchmark is no longer how bad things are in comparison with the recession of 1981-83 but rather how bad things are in compari son with the 1930s. For a variety of reasons, the comparisons to neither the 1980s nor the 1930s are useful. Many of the negative statistics can be compared and found to be similar. Unfortunately, many of the policy mechanisms that helped address the fiscal crisis in cities and states in the 1970s and


Torsional oscillator measurements of 3He-4He mixtures confined in aerogel show evidence of a well defined phase separation region. This region is deiached from the superfluid transition line, opening up a region of miscible superfluid mixture at high 3He concenlration. PACS numbers: 6Z60-g, 6Z40-w, 67.40. Yv Recent experiments studying the nature of superfluid transitions of 4He 1-3 and liquid-vapor phase separation of 4He4 and N25 entrained in porous silica aerogel found intriguing results that are distinct from that found with other porous media. Silica aerogel is a highly porous glass consisting of a tenuous network of Si02 strands interconnected at random sites. 6 The silica network is formed via a sol-gel process. In order to preserve the delicate structure, the solvent remaining from the gelation procedure is removed at a temperature that is above its critical temperature. The open volume fraction of the aerogel ranges from 0.85 to 0.998; in other words, solid silica constitutes from 15 to 0.2 percent of the total available volume. 7 Vapor pressure isotherm measurements indicate an extremely large surface area, typically 580 to 800 m2/gm, s If we combine the surface area and density information, the silica network in aerogel can be modeled as thin strands of roughly 30-~ in diameters. The random and near fractal-like network, 9 the narrow strand diameter and the extreme high porosity are some of the properties that separate light aerogel from other porous systems. In spite of the random environment provided by aerogel, an exceedingly sharp superfluids transition is found for the entrained 4tie. Whereas the transition temperature Tc is depressed from the bulk lambda temperature Tx by only several millikelvins, the nature of the transition for 4He in aerogel of 0.94 and 0.91 open volume fraction is completely altered. 1-3 If the temperature dependence of the superfluid fraction p~/p near Tc is expressed as a simple power law of the form

Purpose
The purpose of this study is to examine a unique application of mega-events theory in a US health-care organization. The organization hosted 50 virtual listening calls (LCs) in the summer of 2020 to understand and to hear their employees' voices regarding their emotions about issues of racial injustice and to solicit their ideas for creating a more inclusive workplace.

Design/methodology/approach
This study used an illustrative, descriptive qualitative design. Using Saldaña's (2015) structural coding approach, data from 388 employees who voluntarily participated in 50 virtual LCs were analyzed.

Findings
A total of eight themes with respective subthemes emerged regarding employees' range of emotions and six themes emerged regarding employees' specific suggestions for creating a more diverse and inclusive organization. This research suggests that hosting these open, virtual LCs enabled a space for employees to authentically voice their perspectives, learn from each other and afforded a powerful learning opportunity for organizational leaders to inform their diversity and inclusion practices.

Originality/value
This study represents a unique application of mega-events theory, focuses on pivotal events in the summer of 2020 that have been nationally and globally impactful and demonstrates the power of listening and learning to inform taking action in a health-care organization already constrained with the ongoing Covid-19 pandemic.


For legal purposes there is a requirement for the validation of signatures and handwritten documents. A helpful method in this respect is the so-called superposed strokes analysis, based on the observation of some characteristics in the writing, such as some letters and their dynamics. This paper introduces a promising new technique for superposed strokes analysis based on conoscopic holography. Through a non-contact 3D measure a 3D profile is created of the superposed strokes that allows the writing dynamics to be determined, such as, for example, if a stroke was drawn clockwise or counterclockwise. We propose a 3D analysis by an opto-electronic system, in order to improve the graphology analysis for off-line signature verification.


Objective To study the germicidal efficacy of plasma air-sterilizing machine in operating theatre.Method The culture dish exposure sampling method was used to assess disinfection effect in the laboratory.Results After the machine was turned on for 60,120 minutes at the environment without people,the average killing rate for the nature bacteria was 84.98%,92.35% respectively.When there were 4~8 people being in operational room,the count of nature bacteria increased to 300 cfu/m3,1250 cfu/m3 respectively,after the machine was turned off at 30 min and 3 h later.The count of nature bacteria increased obviously along with time length and personnel movement but was lower than 200 cfu/m3 with the machine turned on in operating.Conclusion Plasma air-sterilizing machine has excellent air disinfection effect,and can keep the count of nature bacteria comply with the requirement of class II circumstance with personnel movement.


Foreign bodies in the specialty of ENT in developing countries represent a major public health problem. Diagnosis is often delayed because the causative event is usually unobserved, the symptoms are nonspecific, and patients often are misdiagnosed initially.

Objective
To explore the relationships among mobile phone dependence and attachment, social support among adolescent students.

Methods
900 students from two vocational colleges in Shandong province were recruited by stratified sampling. They were assessed with Experiences in Close Relationships Inventory (ECR) Chinese version, Social Support Rating Scale and Mobile Phone Addiction Tendency Questionnaire.

Results
There were no significant differences of adolescent students' mobile phone dependence on gender, child status, and native place. The score of middle vocational school students' mobile phone dependence (45.84±12.64)was significantly higher than that of higher vocational college students(40.68±9.72), and there was significant difference between them (P<0.01). Mobile dependence was significantly positively related with attachment anxiety(r=0.469, P<0.01), and was significantly negatively related with social support(r=0.149, P<0.01). Attachment anxiety and social support were the direct predictors of mobile phone dependence, and social support played the partial mediating role between attachment anxiety and mobile phone dependence.

Conclusions
Mobile phone dependence is a common phenomenon among adolescent students, and the middle vocational school students' mobile phone dependence is more serious than that of the higher vocational college students.There are close relationships between mobile phone and attachment, social support.Attachment anxiety is not only directly but also indirectly associated with mobile phone dependence by social support.

Key words:
Mobile phone dependence; Attachment; Social support


Background: Dental imaging in pregnant females may engender anxiety and consequently, be detrimental to both maternal and foetal oral health. Objective: The aim of this study was to assess the degree of knowledge present in women regarding the use of dental imaging in pregnancy. Patients and methods: Social media platforms were used for the online dissemination of a structured questionnaire to females who were either studying or employed within the medical sector. The questions were designed to elicit the degree of knowledge of the women with respect to the measures taken to protect the foetus from ionising radiation during dental imaging, the safest period for dental images to be acquired, the types of dental radiographs that could be performed and the risk to the foetus (e.g. radiation-induced neoplasia or malformations, as a consequence). Results: A total of 98 subjects, of whom 77.6% (76/98) were aged less than 30 years, filled in and returned the questionnaires. The majority (50%) evidenced a considerable lack of knowledge regarding dental imaging. Opinions proffered suggested that it was safe during the first trimester of pregnancy (14.2%), that panoramic imaging was contraindicated during pregnancy (>50%) and that there was a high risk of associated foetal malformations (14.2%). Conclusions: The data suggested that the study population, who had some level of clinical awareness, had little knowledge of the protective measures undertaken for dental imaging during pregnancy. Students, qualified personnel and healthcare workers would benefit from additional education (e.g. courses or lectures) on this topic.


Kinetics of molecular hydrogen produced from the radiolysis of the system of water and Al2O3– nanoparticles with different sizes were studied. It was determined that, the molecular hydrogen yield of liquid solutions of smaller-sized catalysts is higher for 1.4–1.6 times than the large-sized catalysts.


I welcome this initiative by the Asia-Europe Business Forum to organize a discussion on opportunities and challenges for financial services in our respective regions. Virtually all significant debate that is taking place today on financial sector regulation and development, whether in advanced or emerging economies, is placed in the context of the crisis and the role that the financial sector played in it. However, there is a significant asymmetry in that debate, as is evidenced, for example, in the discussions on post-crisis financial regulatory strategies in the G20 process. It is by now fairly clear that significant differences in regulatory frameworks across countries contributed to very different outcomes in terms of both the role of national financial sectors in the crisis and, in turn, the impact of the crisis on the financial sectors themselves. Within the G20 process, this has resulted in concerns about a "one-sizefits-all" regulatory response to the crisis. However, on a more constructive note, it has also contributed to the emergence of a collective view on balancing the role of the financial sector in the development process with the need for global co-ordination on regulation in the face of increasing global integration of both financial systems and economies as a whole. This "emerging market perspective" was the subject of a seminar organized in Seoul as a prelude to the recent G20 Finance Deputies meeting in Gwangju, Korea, earlier this month. I believe that this perspective provides an important foundation for sustaining a meaningful dialogue between advanced and emerging economies, of which this forum is an example.

This work deals with the problem of information and communication technologies in the educational process, particularly in the process of teaching Russian to foreigners. These technologies have ample opportunities to influence the style of teaching and methods of obtaining knowledge by students; they can increase the effectiveness of teaching Russian language to the maximum. The article describes the experience of the use of technological resources in teaching Russian as a foreign language. Use of IC technology in the classroom is considered from different points of view: 1) as a form and method of supplying educational material; 2) as the training of teachers.


Radon is a naturally occurring radioactive gas, formed during the decay of uranium in the ground. When it surfaces into the open air it is quickly diluted to a harmless concentration but if it enters a building it can become trapped and potentially dangerous levels can accumulate. Indeed, there are around 2500 deaths in the UK every year from lung cancer, linked directly to long-term exposure to high radon concentrations. This article explains how precast concrete beam-and-block flooring can deal with the challenge of unwanted radon.


The properties of implant materials used in humans may have important influences on the outcomes of clinical treatments. Recently, titanium and titanium alloys have been extensively employed as in-vivo implant materials, due to their generally favorable biocompatibility, high resistance to corrosion, and relatively low cost. On the other hand, even when using chemically identical materials, the biocompatibility of an implant or its stability depends heavily on its surface structure, as well as the thickness and properties of the surface oxide film. As the characteristics of the implant surface have been reported to play an important role in the in-vivo reactions of implants, a great deal of interest has recently been focused on different surface treatment methods. Currently, there are a variety of methods with which titanium implant surfaces are treated. The anodizing method is an electrochemical technique, which forms a rough, thick oxidized capsule with nanotubular structures on the implant surface. To increase the biocompatibility and bone regeneration and to improve the current shortcomings of Ti and Ti alloy (Ti6Al4V)implants, we applied a uniquely fabricated nanotubular coating over the surface of such implants.Copyright © 2010 by ASME


A non-paraxial accelerating beam (NAB) is generated through second harmonic generation. The nonlinear generation not only enables us to obtain a NAB at new wavelengths, but also presents an efficient way to control the NAB.


Abstract In 2004, a theory positing that Western Europeans were among the first peoples to colonize North America was published within the pages of World Archaeology. Ten years later this theory continues to provoke academic debate (Balter 2012; Curry 2012; Runnels 2012; Anderson 2013; Bawaya 2013; Morrow 2014) and ignite public imagination (Cook 2012; Vastag 2012; Coghlan 2012) thanks to the publication of Across Atlantic Ice (Stanford and Bradley 2012), the most recent, comprehensive and accessible presentation of what has come to be known as the "Solutrean Hypothesis". In considering how debates over entry routes into North America can be taken further, we review the technological logistics of a North Atlantic crossing and Amerindian and European genetics, examining the validity of the Solutrean Hypothesis in 2014.


The middle course of the Shinano River is situated in the north-eastern part of Fossa Magna which is known as a Green Tuff region. This region has experienced active crustal movement since the Tertiary period. Along the middle course of the Shinano River, fluvial terraces are distributed. The geology of this region mainly consists of unconsolidated rocks, so-called the Uonuma Formation. This formation is composed of silts, sands and gravels, and is 2000m thick in maximum. The course of the Shinano River is one of the syncline of the Uonuma Formation which extends SST-NNE. Terrace plains of this region are classified into nine groups, by the geomorphological and tephrochronological methods. The writers tried to make clear the relation between the displacement of the terrace plains and the crustal movement presumed by the geological structures of the Tertiary formation, and to investigate the nature of the crustal movement after the formation of the terrace plains. Main results are as follows. 1) As for the terrace plains formed at the same stage, it is clear that the quantity of their displacement is proportional to the degree of dip of the Uonuma Formation. For example, the displacement of the first terrace along the right bank of the Kiyotsu River varies from 2 to 10 degrees proportionally to the increase of dip of the Uonuma Formation. In the place where the bed rocks are horizontal, no displacement of the terrace plains is observed. 2) In a same place, it is to be noted that the higher and older terrace plains show more amount of displacement than the lower. It is also noticeable that the terrace plains along the each tributary converge towards the course of the Shinano River. A close relationship was found between the mode of the crustal movement during the late Quaternary period estimated from the displacement of the terrace plains and the mode of the crustal movement since the Tertiary period, presumed from the geologic structures. It may be concluded that the mode of the crustal movement since the Tertiary period has continued till recently and the displacement of terrace plains show latter portion of the crustal movement.


High performance scientific computer systems traditionally have been compared using individual job performance metrics. However, such metrics tend to ignore highlevel system issues, such as how effectively a system can schedule and manage a varied workload, how rapidly the system can launch jobs, and how quickly it can recover from a scheduled or unscheduled system outage. Yet highlevel issues such as these are now among the most important factors in the overall effective performance of a system. This article discusses these issues in some detail and then describes a new performance test, called the "Effective System Performance (ESP)" benchmark, which we are developing to measure system-level performance.
