Objective
To analyze influence factors of the level of plasma n-terminal pro-brain natriuretic peptide(NT-proBNP) in patients with metabolic syndrome.

Methods
Two hundred cases patients with the metabolic syndrome in KaiLuan General Hospital from April 2012 to April 2015 were randomly selected as the observation group, and 200 cases non-metabolic syndrome patients were randomly selected as the control group.The plasma NT-proBNP levels of the two groups were compared.Pearson correlation analysis and multiple linear regression analysis test were used to analyze the influence factors of the level of plasma NT-proBNP in patients with metabolic syndrome.

Results
The level of plasma NT-proBNP of the observation group and the control group were (79.23±20.16) pg/L and (102.25±27.26) pg/L respectively, the observation group was significantly lower than the control group, and the difference had statistical significance(t=4.154, P<0.05). The pearson correlation analysis showed that in observation group the plasma NT-proBNP level were positively correlated with the age, Cr, UA, aortic root diameter(AOD), left ventricular mass(LVM), left atrium diameter(LAD), left ventricular end-diastolic diamete (LVIDd), end-diastolic wall thickness after(LVPWd)(r=0.376, 0.467, 0.167, 0.237, 0.392, 0.484, 0.374, 0.234; P<0.05), and negatively correlated with BMI, TG, TC, LDL-C, Hb and left ventricular ejection fraction(LVEF)(r=-0.167, -0.253, -0.187, -0.342, -0.354, -0.563; P<0.05). The multivariate Logistic regression analysis showed that in observation group, age(OR=1.236, 95%CI 1.072-2.726, P<0.05), BMI(OR=2.256, 95%CI 1.346-2.983, P<0.05), SBP(OR=1.687, 95%CI 1.183-3.209, P<0.05), DBP(OR=1.125, 95%CI 1.052-2.037, P<0.05), FPG(OR=1.887, 95%CI 1.495-3.494, P<0.05), TG(OR=1.504, 95%CI 1.256-2.609, P<0.05), LVMI(OR=1.983, 95%CI 1.363-2.574, P<0.05) and LVEF(OR=1.485, 95%CI 1.147-2.485, P<0.05) were independent factors affecting the level of plasma NT-proBNP.

Conclusion
The level of plasma NT-proBNP in patients with metabolic syndrome is significantly lower than the patients without metabolic syndrome, the reason may be related to the increase in body mass index.

Abstract : In October 1984, severe vibrations of the outlet works gate tower of Gillham Dam, southwestern Arkansas, were observed by US Army Corps of Engineers project personnel. The reservoir elevation was about 50 ft above conservation pool when this occurred. Prototype tests were conducted to determine the severity and cause of vibrations of the intake tower at Gillham Dam. The test program measured the vibrations at the intake tower, wet well, and both service gates; sluice pressures upstream and downstream of each service gate; and the air demand through both air vents. The vibration data recorded on the intake tower and the wet well showed a predominant frequency of 4 cps. This correlates with the upstream pressure fluctuations measured. The tests in which motion was most severe occurred when gate 1 was at an opening of 4.8 ft or higher....

N-benzoyl-N'-phenylthiourea (BFTU) compound is similar to amprenavir derivatives in the urea compound, chloroquine in the -NH group, and the benzene ring, which is a potent antiviral. This study evaluated the effect of lipophilic, electronic, and steric parameters of the BFTU compound on the antiviral activity of Covid-19. In silico docking using Autodock 4.2 to confirm the activity and pkCSM webserver to predict bioavailability and toxicity. The SARS-CoV-2 receptor was binding pocket with the Protein Data Bank (PDB) code 6LU7. Two and three dimensions of BFTU were generated using Marvin Sketch 20.4 and UCSF Chimera. Steric parameters affected the antiviral activity more than lipophilic and electronic parameters. A linear relationship was obtained on lipophilic, steric, and electronic parameters on activity, and a non-linear was on bioavailability and toxicity. The best activity was predicted for the N-benzoyl-N'-2,4-dichloro-phenylthiourea compound with a docking score of -9.12 kcal/mol. BFTU compounds are more potent as antiviral activity of Covid-19 compare to the reference drugs.

I. Carbonate ofLime Calcuili. -Ihad stated in my lecture that calculi having this composition were very rare, so rare that they were not represented in the Museum of the Royal College of Surgeons. Dr. Bird of York wrote to correct me on this point: and I have to acknowledge that I had overlooked the supplementary catalogue, in which a carbonate of lime calculus was described and its composition recorded by my friend Mr. Taylor. The specimen was, with others, presented by Dr. Bird to the College of Surgeons, and is a very fine one. I cannot altogether regret my mistake, for it has put me in communication with Dr. Bird, and has led him to give me an opportunity of examining another most interesting calculus, about which I shall have a word to say presently. Thanking Dr. Bird for his courtesy, I pass on to another carbonate calculus, described by Dr. Spencer Smyth of Forest Hill, in the BRITISH MEDICAL JOURNAL of June 30th,I877, and said to have been voided by a lady a few days after her confinement. Dr. Smyth was good enough to send it to me for further examination. The calculus, which is before you, is elongated and irregularly foursided; in length, inches; in greatest breadth, Q1inch; it is perfectly white and powdery on the surfdce, and is of light specific gravity. A portion heated on platinum fuses without blackening, and without giving off any smoke or odour, leaving a small clear glassy deliquescent residue, readily soluble in water. The solution is strongly alkaline, and gives no precipitate with phosphate of soda, or ammonia, or carbonate of ammonia, or oxalate of ammonia. No uric acid reaction is obtained. A fragment placed on a slide, moistened with distilled water, and examined under the microscope, dissolves rapidly and completely, disengaging air-bubbles. The water is examined to ensure its freedom from acidity. The solution effervesces briskly with acids, and no subsequent precipitate of uric acid is formed. The substance of the calculus during the process of solution is transparent, and composed of small aggregated and mutually compressed spheroidal masses,having a radiate crystalline arrangement. A watery solution of the uncalcined substance gives no precipitate with phosphate of soda, or with ammonia or oxalate of ammonia. On the introduction of the substance into the flame of a Bunsen burner, it gives a yellow tint to the flame. In the spectroscope, only the sodium line is seen. Noammonia is set free by caustic alkali. The diagnosis is that the so-called calculus consists of carbonate of soda, or more probably of a crystal of common washing soda, whichhas absorbed carbonic acid from the air and become bicarbonate. It is evidently not an urinary product at all, but musthave found its way accidentally ot by some trickery into the position that suggested the idea of its being passed from the bladder. On coming to this conclusion, I wrote to Dr. Spencer Smyth, who, in reply, handsomely gave me permission to do what I pleased with the specimen, adding that the nurse distinctly stated that the patient voided it into the urinal with a large quantity of urine; and, as Dr. Smy th further suggested that I might, after a complete revision of my analysis, mention the case in one of my cliniues, I take advantage of his kind and frank permission. The occurrence is a very curious one, and well illustrates the sort of deception against which we have to be on our guard in examining urines and deposits. 2. Spontaneous Disruption of Calculi.-Soon after the publication of my last lecture, I received two parcels of fragments of disrupted calculi, closely resembling those described by me. They were sent by Mr. Lockhart of Blackheath and by Mlr. G. Buckstone Browne respectively. Mr. Lockhart sent me twelve fragments, which e regarded as portions of three or four calculi. They had been passed as they were sent to me, and as I now exhibit them, at different times, between two and three years ago, by a gentleman of the age of fifty-six, who experienced great pain during their passage, but not before or after.

This paper considers an investment decision problem in continuous-time frame work, in which a firm can switch between a risky investment and a riskless investment. In this paper, I proposes a method to derive a closed-form solution to this (S, s) control problem. As a result, I derive the values of the conversion options and the critical thresholds analytically. The values of the conversion options are very helpful for us to interpret conversions between operations as exercises of the options.

Background Self-management education programs (SMEPs) are potentially effective in the symptomatic management of COPD. Little is presently known about the effectiveness of these programs in Chinese COPD patients. The objective of this study was to evaluate the effectiveness of a specifically designed SMEP on levels of self-efficacy in Chinese patients with COPD. Materials and methods Based on the Medical Research Council framework for evaluating complex interventions, an exploratory phase randomized controlled trial was employed to examine the effects of an SMEP. Self-efficacy was the primary outcome using the COPD Self-efficacy Scale, measured at baseline and 6 months after the program. Qualitative data were sequentially collected from these patients via three focus groups to supplement the quantitative findings. Results The experimental group displayed significant improvement in their general self-efficacy (Z =−2.44, P=0.015) and specifically in confronting 1) physical exertion (Z =−2.57, P=0.01), 2) weather/environment effects (Z =−2.63, P<0.001) and 3) intense emotions (Z =−2.54, P=0.01). Three themes emerged from the focus groups: greater disease control, improved psychosocial well-being and perceived incapability and individuality. The connection of the quantitative and qualitative data demonstrated that individual perceptual constancy of patients could be a determining factor modulating the effectiveness of this type of intervention. Conclusion These findings highlight the potential putative benefits of an SMEP in Chinese patients with COPD. Further attention should be given to cultural considerations when developing this type of intervention in Chinese populations with COPD and other chronic diseases.


The invention provides a method for manufacturing a PCB coaxial cable and the PCB coaxial cable. The method comprises the following steps that a medium layer used for wrapping a core wire is manufactured, and two linear metal connectors located in the medium layer and on the two sides of the core wire are manufactured, wherein the metal connectors and the core wire do not cross; the surface of the medium layer is etched to form at least two grooves through which the two metal connectors are exposed; the core wire is located in the part, between the grooves, of the medium layer; the grooves and the surface of the part, between the grooves, of the medium layer are metallized, so that a metal shielding layer wrapping the part, between the grooves, of the medium layer is formed, and the PCB coaxial cable is obtained. By the adoption of the processes that the medium layer is etched to form the two grooves, the grooves are filled, and the part, between the grooves, of the medium layer is metallized, the metal shielding layer can be easily and rapidly formed around the core wire, and the coaxial cable with the shielding layer is obtained. Compared with the prior art, the number of processes is small, and processing efficiency is high.


The transmission error of a pair of spur gears is detected by an optical method and recorded continuously as a function of time. Measurement of the alternating component of the error is repeatable within ?5 ? 10-5 in., and of the mean value within ?1 ? 10-4 in., at base circle radius, at any speed in the range 0-6000 rev min-1 and at any load within the capacity of the gears. Records are taken on photographic paper wrapped round a drum which rotates with one of the gears being tested. In this way the wavelength of record per cycle of tooth-engagement is made independent of speed and comparison of static and dynamic behaviour is facilitated. The method of measurement is applicable only to a pair of gears with the same number of teeth.


Abstract Perceived memory problems may cause older adults to limit functional activities such as driving. For those individuals living in non-metropolitan communities, greater distances between activities, lack of public transportation, and fewer support systems may make reducing driving frequency less feasible. We hypothesized that older adults in non-metropolitan communities would be more likely to continue frequent driving even if they also perceived memory problems. We used the National Health and Aging Trends Study to examine the association between reported memory difficulty and the frequency of driving. These data were then stratified by metropolitan versus non-metropolitan classification using both ordinal logistic regression and Chi-Squared testing. In both metropolitan and non-metropolitan communities, respondents were more likely to report reductions in driving frequency if they also reported memory problems. However, in both metropolitan and non-metropolitan communities, the majority of respondents reporting fair or poor memory continued to report frequent driving; and, there were no statistical differences in frequency of reported driving between metropolitan and non-metropolitan respondents. These analyses suggest that strategies are necessary in both metropolitan and non-metropolitan areas to help older drivers with perceived memory difficulties to recognize when they need to limit driving. Further research is necessary to determine which strategies are likely to be effective in metropolitan and/or non-metropolitan communities.


Cultural competence (CC), or the ability to provide high-quality health care within the context of a patient's race, ethnicity, language, religious beliefs, or behaviors, is an essential component of professional practice. This study aimed to determine the relationship between students' level of CC and their ability to provide CC care. Athletic training students in 62 accredited undergraduate athletic training programs (N = 421) completed a survey that included 20 questions to determine CC and one question regarding confi dence in delivering care. On calculation of means and standard deviations, one correlation sought to identify relationship, and ANOVA with contrasts was utilized to determine diff erences in CC by confi dence level. Results demonstrated that athletic training students were culturally aware, but not profi cient, while having high levels of confi dence in delivering appropriate care. The correlation results demonstrated a lack of relationship between confi dence and CC, whereas ANOVA results were signifi cantly diff erent between cohorts.

This article discusses how the Court of Justice of the European Union (CJEU) deals with international law issues. While the EU and the Court itself are often presented as being `friendly' towards international law, recent cases have shown a trend towards a more guarded approach by the Court. The article first examines recent literature on the CJEU's relationship with international law which demonstrates an oscillation between `openness' towards international law and an approach that emphasises the autonomy of the EU legal order. It then discusses what rules exist to guide the Court in determining its relationship with international law. To what extent do the EU Treaties, the legal traditions of the Member States or international law itself determine how the CJEU should deal with international law issues? The next part examines how the CJEU has dealt with international law in practice. The CJEU has progressively developed tools to limit the effect of international law, as it attempts to strike a balance between respect for international law and the need to safeguard the integrity of the EU legal order. It discusses some recent cases where the CJEU dealt with key international law issues in order to demonstrate how this relationship is shaped in practice. The final part seeks to understand why the Court seems to oscillate between an open and a closed approach to international law. It is posited that this can partly be explained by whether the Court is acting in its capacity as an international or a domestic court.


The nanoscaled tris-(8-hydroxyquinoline) aluminum (AlQ3) crystalline film was synthesized by vapor condensation. It was stacked with nanometer-sized rods, approximately 100 nm wide and 1 μm long, and had a surface roughness of about 100 nm. The vibronic progression with several separated peaks was observed in the photoluminescence spectrum at room temperature. It is attributed to the crystallinity of AlQ3 and the coupling of vibrations of the individual ligands to the fluorescence transition. The emission current was also observed with a turn-on field of 12.0 V/μm, and a current density of about 0.8 mA/cm2 at 22 V/μm. Therefore, the AlQ3 crystalline film provides a choice for field emission.


In order to make the loss of waste products go up to minimization in mechanical working for the machine parts,the position of cutting tools in machine bed should be adjusted. Thus,the distribution of dimension for the worked parts can be met the need of assembling precision and accuracy. At the same time,the cost of working can be reduced to minimization.


Regression Testing is an important maintenance phase testing activity. The importance of this activity lies in the fact that it imparts confidence and accuracy in the modified code, as well as keeps a check on the unmodified parts, if they are affected or not. But there is a severe requirement to reorder the development testing test suite because of the constrained software development budget, time and effort. So techniques have to be developed to prioritize test cases to reduce budget, time and effort constraints effectively. In this paper implementation and analysis of an existing fault based regression test suite has been done. The prioritization algorithm is based on the nature inspired algorithm called Bee Colony Optimization (BCO) algorithm. The algorithm is a two step procedure which maps the food foraging behavior of scout bee and forager bee one after the other to reach to the solution. The analysis of the examples using the code developed indicates that the two step BCO algorithm is able to produce results which are comparable to optimal results.


Chronic/recurrent tonsillitis is a persistent inflammation of the tonsils due to recurrent acute or subclinical infections. During acute tonsillitis, infection may persist in the fibrous tissue and cause another tonsillitis attack after days or weeks if proper antibiotic treatment is not provided for a sufficient time. Furthermore, inflammatory scrapings inside the crypts may cause subclinical infection and subsequent tonsillitis attacks (1). Generally, a diagnosis of chronic/recurrent tonsillitis is based on tonsillitis or throat pain that recurs three to four times a year and does not respond to sufficient antibiotic treatment (2). A recurrent throat pain is generally accompanied by fever, weakness, and arthralgia. Secondary foul breath (halitosis) that fills tonsil crypts may also be present (3, 4). Chronic tonsillitis is in fact an adult disease; however, it can be observed at all ages. Like any other chronic disease, tonsillitis can also trigger psychological disorders. Numerous studies on the relationship between chronic/recurrent tonsillitis in adults and psychological disorders and quality of life are available, whichcompare the quality of life of patients before and after surgery (5) or investigate the quality of life and mental health in pediatric patients (6). This study sought to understand the complex relationship between depression and anxiety and chronic/ recurrent tonsillitis in adult patients, which was probably related to various psychiatric disorders owing to its symptoms (pain, weakness, fever, and halitosis). SUMMARY Chronic/recurrent tonsillitis is a condition that affects the quality of life with symptoms such as pain, fever, halitosis, and so forth. However, the effect of this condition on depression and anxiety has not been studied. Therefore, this study aimed to investigate the complex relationship between chronic/recurrent tonsillitis and depression and anxiety in adult patients. The study included 60 female and 60 male patients and 25 healthy male and 25 healthy female controls, aged 18–40 years. The participants were made to fill out the Beck depression and anxiety inventories (BDI and BAI). Those who met the inclusion criteria were included. The averages and cutoff values of the total scores were investigated separately for males and females. For both males and females, the averages of total BDI scores (P < 0.043 and <0.035, respectively) and total BAI scores (P = 0.019 and 0.027, respectively) were significantly higher in group 2 than in group 1. This study was novel in exploring the relationship between chronic/recurrent tonsillitis and depression and anxiety in adults. The findings of this study might enhance the understanding on this subject and serve as a valuable guidance for the interested researchers.


The ubiquitous use of smartphones, smart devices, and low-cost sensors, has fostered much attention around the Internet of things (IoT). The Internet of Things has led to the manufacturing of more IoT-related products ranging from devices to applications. The sensors in an IoT network provide data on the environment in which they are deployed and interact with other devices and the applications in the broader IoT ecosystem. IoT components do not necessarily adhere to the same standard and so can be very heterogeneous in a particular environment. This can create challenges in the collection and monitoring of heterogeneous data in real-time as well as monitoring the infrastructure itself. Such data collection is not only important for the analysis of the environment but also for monitoring the health of the devices and operational components, such as software elements. In this paper, we introduce an architecture aimed at collecting, visualizing, and monitoring streams of data from sensors and from infrastructure components. The ThingsBoard IoT platform is used for data collection and visualization. Node-Red is used to categorize the data on the sensor name. Experiments using sensor data sets are provided to illustrate the approach, processing, and visualization.


The aim of this study was to clarify the effects of gestational age and birth weight on outcomes of the infants. Medical records of 36 infants with trisomy 18 admitted to Tokyo Women's Medical University Hospital from 1991 to 2012 were reviewed retrospectively. We compared clinical characteristics between term infants (n = 15) and preterm infants (n = 21). There were one very‐low‐birth‐weight (VLBW) term infant (5%) and 12 VLBW preterm infants (80%). Although there were no significant differences in clinical characteristics and provided management between the two groups, none of the preterm infants achieved survival to discharge. On the other hand, 6 of 21 term infants (29%) achieved survival to discharge (P < 0.05). Similar results were obtained for comparisons between the VLBW infants and non‐VLBW infants. Multiple logistic regression analysis revealed that shorter gestational age had a more negative impact than lower birth weight to survival to discharge in infants with trisomy 18. In both preterm and term groups, the infants who died before 30 days commonly died of respiratory failure or apnea. Whereas, the infants who survived more than 30 days mostly died of heart failure. © 2015 The Authors. American Journal of Medical Genetics Part A Published by Wiley Periodicals, Inc.

A radiation resistant low-OH fiber was studied and its performance contrasted to that of high-OH material. Several fibers with differing core compositions were also studied.


Many of the retailers try to make better profits private labels as a strategy. For that they have to maintain the performance of private labels to gain their expected profit margins. Maintenance of only private brands in the store may not bring good results and maintenance of national labels alone may not result in achievement of required profit margins. In saturated markets, given the intensity of competition, customer bonding has become more important for the simple reason that such relationships generate greater profits for a firm (Juhl, Kristensen, & Ostergaard, 2002; Reichheld & Sasser, 1990). So they were maintaining a tradeoff between labels. And the tradeoff should be in a way such that profit has to be achieved and product availability has to be in a satisfactory level, and all this is to happen while strong bonding is created between the customer and the private labels. This study is taken to find out the performance of private labels over national labels in the Big Bazaar store. The data collected related to this study is analyzed and used for testing the hypothesis using Signed rank test statistical tool.


The diet variation of thread herring Opisthonema libertate , in relation to age and latitudinal distribution in the Gulf of California, was analized during the 1987 fishing season. Diatoms were the most important components of dietary groups, followed by pelagic crustaceans, fish eggs and dinoflagellates. There were no significant variations with respect to age groups, but significan! latitudinal differences for diet composition were found. These differences were attributed to the time-space distribution of the herring feeding resources. O. libertate is an opportunistic forager, rather than a specialized filter feeder.

Thirteen different plant and animal protein media such as nutrient agar medium-I, nutrient agar medium-II, Wouts medium, modified Wouts medium, wheat flour medium, modified wheat flour medium, egg yolk medium-I, egg yolk medium-II, modified egg yolk medium, dog biscuit medium, modified dog biscuit medium, bengal gram medium-I and bengal gram medium-II were tested for mass multiplication of entomopathogenic nematodes such as Heterorhabditis bacteriophora strain KKMH1 and Steinernema carpocapsae strain APKS2 by in vitro solid culture technique. Results showed that modified Wouts medium and nutrient agar medium-I multiplied significantly higher numbers of 39.02 39.14 lakh IJs of H.. bacteriophora strain KKMH1 per 250 ml flask. The IJs produced from these media were more virulent to cotton pest such as Helicoverpa armigera, Earias vitella and Spodoptera litura. For multiplication of Steinernema carpocapsae strain APKS2, modified dog biscuit medium and nutrient agar medium-I got significantly higher IJ populations of 49.69 52.31 lakh /250 ml flask. The IJs multiplied on these media caused 100% mortality of H. armigera, E. vitella and S. litura. The results of this study suggest that mass production of the H. bacteriophora strains KKMH1 on modified wouts medium or nutrient agar medium-I and S. carpocapsae strain APKS2 on modified dog biscuit medium or nutrient agar medium-I are promising option while promotion of these strains as potential bio-pesticide against cotton insect pests H. armigera, E. vitella and S. litura.

An extension of the theory for charge emission from monoenergetic grain boundary interface states by thermal emission (TE) and thermionic-field emission (TFE) is presented for states distributed in energy, whose density is either constant or slowly varying with energy as compared to the Fermi function. The importance of TFE increases with the doping concentrationN, and the voltage applied across the grain boundaryV, and decreases with increasing temperature. Interpretation of the interface state density according to the Seager-Pike-Ginley treatment, which neglects thermionic-field emission, is shown to overestimate the density and underestimate the interface state energies relative to the majority-carrier band.

The drive towards evidence based approaches in medicine, is designed to inform clinical practice. To this end, there are journals (generally not open access, e.g. Evidence Based Mental Health) and internet sites dedicated to informing mental health care practitioners of evidence on a range of issues related to clinical practice, including prescribing. This is certainly to be welcomed insofar as both clinicians and patients might feel more comfortable with treatment decisions.


Purpose - The topic of competence-based marketing has attracted much attention from business scholars, further exploration of competence-based marketing capability is especially important. The main purpose of this study is to address and investigate the relationship between market orientation and original equipment manufacturer (OEM) suppliers' competence-based marketing capability, along with the impact of competence-based marketing capability on product-linked development and relation-linked development.   Methodology -  Based on a sample of 119 Taiwan's OEM suppliers, we used Smart PLS 2.0 to perform SEM and to evaluate both the quality of the measurement model and the interrelationships of the constructs. Findings - Empirical testing of 119 OEM suppliers suggests that a proactive market orientation has a positive influence on the development of competence-based marketing capabilities. Furthermore, the development of competence-based marketing capability leads OEM suppliers to engage in product-linked and relationship-linked development. Conclusion - The topic of competence marketing has attracted much attention from business scholars; however, no empirical studies have measured companies' capabilities in competence marketing. Therefore, the framework of this study followed linkages developed from the resource-based view (strategic orientation → organizational capabilities → organizational performance) for the purpose of exploring the antecedents and effects of CBMC.

Abstract : Carbon fibers and glass fibers in brittle matrics fracture by a number of distinguishable mechanisms, matrix cracking, failure of the fiber-matrix bond, fiber fracture, fiber pull-out, and so forth. A large amount of data of fiber debond length and fiber pull-out length have been collected and summarized in cumulative probability diagrams which show the distribution of extreme values. Models of fracture, together with the fracture data are used to construct fracture energy diagrams which show the origins of toughness and the dominate mechanism of failure. Failure analyses have been carried out on glass fibers and carbon fibers in epoxy and polyester resins, and on hybrid composites. Certain generalisations about fracture behavior can be drawn from comparisons of the cumulative probability and fracture energy diagrams. (Author)


Reactive extrusion consists in using an extruder as a continuous chemical reactor. It is not a recent process, but it has been rapidly developed during the last thirty years and is more and more used today for the chemical modification of existing polymers. Among the various extrusion systems (single screw extruders, counter- and corotating twin-screw extruders, co-kneaders), the corotating twin-screw extruders are today the most widely used in reactive extrusion. After a presentation of the main advantages and drawbacks of the reactive extrusion, we will describe the way to control the process through on-line and in-line monitoring. Then, a modelling approach based on continuum mechanics will be presented, followed by an example of industrial applications of this particular process.

Habilitation of modern specialists of the health service sphere in a higher educational institution envisages the purposeful formation of their standard professional identity that will provide their future professional sustainability. This shaping of professional identity in the higher educational institution as a task for educational and professional process needs to reproduce compliant pedagogical conditions, e.g., creation and organization of functioning of the educational-&-professional community as a site for professional and communicative self-affirmation and for professional self-determination of a future specialist. Creating and functioning of the educational-&-professional community in modern university actualizes in two forms — real (full-time) and virtual (remote). A pedagogical management which helps to form the professional identity in the conditions of the educational-&-professional community envisages organization of its functioning, solving educationally and professionally prompted tasks by the students, referring the pedagogical request to the specialists who will join this community and will provide fulfillment of the identity processes via students' vocational self-presentation and reflective self-analysis, via experts' assessment, facilitation and analysis of adequacy for the students' vocational choice — these will serve as the basis of further perfection of educational and professional development of a higher educational institution. Approving the teaching doctors' pedagogical willingness to create the educational-&-professional community may be achieved within the cyclic retraining which has confirmed its efficiency.

The cold laying of PJP-lines has become widely used as standard procedure especially in the range of smaller and middle sized nominal widths. In one of three trial lines in Dinslaken however, a phenomenon occurred, that prevented the district heat supply Niederrhein for years from further continuing cold laying method: the geodetic displacements measured with extreme accuracy in one of the trial sections exceeded the values calculated in theory by threefold. Only now the cause for this extreme deviation between calculation and practical experience was found. The intensive study of the reports and design documents as well as comparative analyses of the lines led to the conclusion that the large displacements in this trial sections was most likely caused by the tree stock. When it is windy, dynamic loads are driven through the tree trunks into the roots underground. Theses of possible »relaxation« or »plastification« of the soil were refuted with these new examinations. From the good alignment of calculations and measuring values from many other lines, however, the reverse conclusion can be drawn, that the friction force formulas available during the beginning of the nineties were quite accurate in respect to the absence of trees.


In this paper, a new compression scheme called hybrid compression model (HCM) is proposed for compressing clusters of similar images. The HCM exploits region growing to segment the median image that created by a cluster of similar images; and further, it uses centroid method to predict the values of original images data. The difference between the predict values and original data is stored for later use of progressive transmission. The experimental results obtained on various images show that our method provides significant improvement in compression efficiency while compared to the traditional centroid method.


Abstract In this paper, we explore the impact of a five-week media literacy curriculum offered to three classes of second grade students (n=51) during March-April 2003. The curriculum included lesson plans pertaining to 1.) news media, 2.) media violence, 3.) advertising, 4.) gender stereotypes and fairytales, and 5.) media production. Analyses of students' weekly journal entries and videotaped verbal responses to the curriculum are included in this report. The findings suggest that individuals as young as seven-years-old, when exposed to a media literacy curriculum, can take a more critical stance toward mass media. ********** Media literacy, often referred to as media education, is the ability to "decode, evaluate, analyze and produce" media in a wide array of forms (Aufderheide, 2001, p. 79). An interdisciplinary endeavor by nature, media literacy encourages inquiry-based learning and the development of critical thinking. Kurfiss (1988) describes critical thinking as what occurs when educators pose problems or questions as an entry point into a topic (such as media). In an effort to extend our knowledge of media literacy beyond University walls, we developed a five-week curriculum, offering lesson plans to three second-grade classrooms (51 students) in a rural, predominantly low-income, public elementary school in a New England town. Based on preliminary meetings with the school counselor, we decided that our five sessions, each 30 minutes in duration, would cover the following topics: 1.) news media, 2.) media violence, 3.) advertising, 4.) gender stereotypes and fairytales, and 5.) media production. Theoretical Framework Two philosophies of media literacy, the interventionist approach and the cultural studies approach, guided our curriculum development and pedagogical style. The interventionist camp constructs media literacy as an attempt to shield individuals (particularly children) from an army of negative behavioral, affective and cognitive media effects while emphasizing the development of critical thinking (Masterman, 2001). Meanwhile, the cultural studies orientation conceptualizes media literacy as an empowering tool through which knowledge and critical thinking skills are developed while acknowledging the pleasure derived from mediated experiences (Lewis & Jhally, 1998). The interventionist framework employs a top-down pedagogical style through which educators offer information, pose questions, and determine the desired outcomes of a media literacy program. However, the cultural studies perspective involves a student-centered approach, encouraging multiple sites of knowledge while emphasizing students' ability to interpret, negotiate and question the meanings of media messages (Christ & Potter, 1998). Despite the contrasting versions of media literacy, both camps share common ground, leading us to believe that the perspectives can, and should, compliment rather than compete against each other. It should be emphasized that the general structures and overall goals of media literacy put forth by the interventionist and cultural studies camps involve "asking questions about what you watch, see, and read" (Hobbs, 2001, p. 25), thereby encouraging critical thinking about the media. Hence, we based our curriculum and pedagogical approach on both traditions, thereby encouraging active learning through two-way discussion while foregrounding both positive and negative aspects of media. Curriculum Goals Based on the aforementioned theoretical constructs, we put forth the following goals: (1) To provide a judgment-free space for second graders to discuss their opinions, emotions, experiences, pleasures and frustrations with various media; (2) To introduce students to concepts pertaining to mass media, including (but not limited to): media, commercial, deceptive advertising, consequences, etc.; (3) To produce general awareness of mass media forms and content and foster a sense that media messages are constructed for economic, political, and aesthetic reasons, among others; (4) To encourage students to think critically about media and ask questions in regards to what they see or hear in their media landscape. …


W IT H the development of emergency social service programs to meet those individual and group needs relating to the war, has come the necessity for establishing in-service training programs within the agencies concerned. In these emergency training situations need has arisen for examining our thinking and practice in social work so that we may discover in what ways our past experience can be useful in these new training programs. One of our concerns in the Personnel Training Unit, Services to the Armed Forces, of the American National Red Cross has been whether or not class experience can provide material that will be helpful in supervision, and if so how this material can be made available for use. In other words, is there any way of sharing with supervisors the responses of individuals to class study, in such a manner that this material can be utilized in assisting new workers to accept and carry job responsibilities? Realizing that the setting within which a problem arises is important in the consideration of that problem, I shall describe briefly the purpose of the Personnel Training Unit of the American Red Cross. The Training Unit at national headquarters has been established in order to acquaint large numbers of new personnel with the rapidly expanding social service program of the American Red Cross and to give training to these persons in how to do the jobs to which they have been assigned. Courses are provided for the study of a variety of services, and class discussions include both job content and the methods of doing specific jobs. Course content and the method of class instruction vary with the needs of the different groups that come for training. In this paper I shall confine my remarks to the Home Service Section of the Personnel Training Unit. This section provides a three-week course of study for newly employed Home Service secretaries, supervisors, and administrative personnel. Each


This study aims to determine the principal academic supervision of teachers and supervision of competence of high school principal supervision by school supervisors in Central Aceh district. The type of research used is descriptive analysis with qualitative approach. The analysis is done by the description of the academic supervision and supervision by the supervisor on the principal. This research was carried out in three schools of SMA Negeri 6, 10, and 12 Takengon from April to August 2017. Data collection technique used interview method, documentation study, observation. Validation is done by triangulation. Techniques Data analysis using qualitative analysis that refers to the theory of Miles and Huberman. The results show that the academic supervision is still low (26%). This is caused by the lack of ability of the headmaster through supervision. Therefore it is necessary to supervise by the supervisor. As a form of coaching, an academic supervision workshop was conducted to the principal by the supervisor. As a follow up of the workshop, the principal supervises his teachers. The results of supervision indicate that the average teacher grade is moderate, ie 73.20. Based on the results of the research, the supervisor is advised to be more varied in carrying out guidance in the future. Workshop method is only one way of doing guidance. This is to improve the competence of the principal's supervision.


Numerical simulations of mean groundwater age are presented for a variety of complex flow systems including heterogeneous aquifers and discretely-fractured porous rock. We apply the finite element models FLONET/TR2 (in the 2D vertical plane) and SALTFLOW (in 3D systems), using the standard advection-dispersion equation with an age source term. The age simulations are applied in a variety of contexts including defining capture zones for pumping wells, characterizing fractured rock aquifers, and for improved understanding of flow systems and geochemical evolution. Applications include real field sites and hypothetical conceptual models. Comparisons are also made with advective particle-tracking derived ages which are much faster to compute but do not include dispersive age mixing. Control of numerical (age) dispersion is critical, especially within discrete fracture networks where high age gradients can develop between the fractures and matrix. The presentation will highlight the broad applications of mean groundwater age simulations and will show how they can be useful for providing insight into hydrogeological systems.


Cognitive-behaviour therapy (CBT) is the recommended treatment for panic disorder, and outcome research has demonstrated its efficacy. However, a central tenet of CBT is that clients become self-therapists, using what they have learnt within therapy post-treatment. Only one previous published study has explored this issue with regards to people making use of CBT for recurrent depression (Glasman et a/., 2004). This study explored the use adults experiencing panic attacks made of CBT after completing CBTinformed group therapy within a primary care setting. Nine participants (four men and five women) were recruited to the study, and consented to a semi-structured interview. The focus of the interviews was around: how clients make use of CBT for panic attacks/disorder after completing therapy; what the client's understanding and perception of factors that helped or hindered the use of CBT after completing therapy is; and how clients understand and perceive their experience of CBT for panic attacks/disorder. Interview transcripts were subjected to Interpretative Phenomenological Analysis. The seven resultant themes that emerged were: beliefs about change; the use of CBT: psycho-education; the use of CBT: behavioural strategies; the use of CBT: cognitive strategies; use of other strategies; obstacles and supports to using CBT; and self-efficacy. The main findings were that clients did engage in self-therapy, using CBTinformed strategies and techniques to manage their ongoing experience of panic attacks. It highlighted that CBT is a learning process, and that participants found some aspects easier to utilise than others. In addition, differences emerged between the participants in terms of which aspects of CBT they gave emphasis to.


ABSTRACT This research entitled 'Prinsip-prinsip Kesopanan dalam Film The Help Karya Tate Taylor : Suatu Analisis Pragmatik' focuses on maxim related to the politeness principles.

Fourth, modesty maxim consist of 9 utterances functioning to minimizes praise of self and maximizes dispraise of self. Fifth, agreement maxim consist of 10 utterances functioning to maximizes agreement between self and other and minimizes disagreement between self and other. Sixth, sympathy maxim consist of 9 utterances functioning to minimizes antipathy between self and other and maximizes sympathy between self and other. It is expected that this research will help students and readers in learning pragmatic aspects, especially about politeness principles. Keywords : Politeness Principles, Maxims, Pragmatic Analysis, The Help Movie


A previously developed dynamic growth simulation model for cut tulip production in a plant factory system which predicts forcing period and flower quality of cut tulips from duration of bulb chilling and forcing temperature was confirmed. In a 1993-1994 experiment in which bulbs were forced at 20°C, irrespective of the duration of their chilling period at 2°C, the simulated values of number of days from planting to anthesis, shoot (cut flower) fresh weight, perianth length and dry weight of the component parts at anthesis correlated well with the observed values. In a 1998-1999 experiment in which the forcing temperature was lowered with the extension of the duration of bulb chilling at 2°C, when the duration of bulb chilling was extended to 26 weeks or longer, shoot fresh weight, perianth length and dry weights of shoot and floral organs at anthesis were underestimated by the model, while the dry weight of daughter bulbs was overestimated. These differences were supposed to be caused by fluctuation in bulb properties and could be diminished by inputting the dry weights of the mother bulb and daughter bulbs at planting into the model.

Excessive disinflation and the flattening of the Phillips curve are recently popular phenomena in many advanced economies. In the environment of low inflation, the fading relationship between the price dynamics and the adjustments in the domestic real activity is vigorously investigated for highly developed economies. Still little evidence has been presented for emerging, small open economies. In this paper I address this issue by investigating the behavior of the Phillips curve for Poland. In particular, I aim at answering the question whether a Phillips curve flattening or a steepening can be observed during the recent abrupt disinflation. The outstanding problem of considerable uncertainty accompanying the model specification is accounted for by estimating a substantial number of regressions and exploring the cross-section properties of the hybrid Nkpc parameters. The results advocate that a statistically significant relationship between inflation and the domestic real activity developments persists. However, in the recently observed disinflation period the Phillips curve tends to flatten as the inflation's sensitivity with respect to changes in economic slack diminishes. That notwithstanding, the impact of external factors rises significantly. Conditional ex-post forecasts suggest that while only a limited number of Phillips curve specifications manage to explain the disinflation process in Poland, employing unemployment gap or real Gdp as economic slack proxies delivers the most accurate inflation forecasts.


The 4 workshop on crab cavities for the LHC high-luminosity upgrade project HL-LHC (LHCCC10) was held from 15 to 17 December 2010 at CERN, Geneva, Switzerland. This document outlines the key conclusions from the LHC-CC10 workshop and summarizes each individual session based on the final presentations by the session conveners and on the subsequent discussions. At LHC-CC10, local crab crossing with the aid of 400 MHz deflecting SRF cavities was identified as the baseline tool for geometric luminosity-loss compensation and luminosity levelling for the HL-LHC. Associated key issues such as machine protection and robust operational scenarios still have to be studied in detail, so as to identify and mitigate potential beam-dynamics or technology limits on implementing and fully exploiting crab crossing at the LHC. Also at LHC-CC10, the decision was taken not to install a KEK-B crab cavity in the SPS. However, it was recommended that all measures to test future LHC prototype cavities with and without beam outside the LHC be taken in order to ensure robust operation of the crab RF structures in the LHC. The 4 workshop on the crab cavities (LHC-CC10) for the LHC luminosity upgrade project (HL-LHC) was held from 15 to 17 December 2010 at CERN, Geneva, Switzerland.


The prenatal diagnosis of a complete trisomy of the long arm of chromosome 1 is reported. Major ultrasound findings included: nuchal thickening, bi‐temporal narrowing, a single choroid plexus cyst, andmild ventriculomegaly. There was a mass in the chest and abdomen, pleural effusion, ascites and a hyperechoic bowel. Skin edema was present. The fetus died at 26 weeks' gestation. A literature review is presented of 17 de novo and two inherited cases with only trisomy 1q. Of note is the fact that 3/5 prenatally detected 1q trisomies have teratomas. A review of the literature reveals a dismal outcome fortrisomy 1q cases if the duplication involves bands 1q25→q32. Copyright © 2001 John Wiley & Sons, Ltd.


An exploratory experiment was conducted to investigate the effects of coffee, guarana, and yerba mate on mood and performance, and to determine any potential of these beverages to overcome the soporific effects of lunch. Seventy-one female students were assigned to four beverages, including a decaffeinated coffee control, and tested on two days (lunch/no lunch), over three sessions (prior to drinking the beverage, and again 60 and 150 minutes after drinking the beverages). Lunch had little effect other than to increase pulse. Guarana increased systolic blood pressure and accuracy on a vigilance task; coffee increased accuracy on the vigilance task; but yerba mate had no significant effects. Further research is recommended before any definitive conclusions about the effects of guarana and yerba mate are reached.


This paper critically analyses 239 scholarly communications published in the inaugural five volumes of Journal of Informetrics ( JOI) to examine growth of literature, types of communications, authorship pattern, collaboration trend, predominant research domains, etc. Subsequent analysis focuses on prolific contributors, degree of collaboration, and time-lag trend. Findings reveal that - publication output doubles over the study period as article publications increase considerably; though single-authored contributions were significant (30 %), majority of contributions were collaborated by two-authors (36 %), while average authorship accounts for 2.28 per communications. Degree of collaboration (DC) was impressive (0.699) but not overwhelming as research collaborations has emanated from 199 higher learning institutions of 32 countries across the globe. Ranking of prolific contributors has shown Prof. Egghe on the top followed by L Bornmann; R Rousseau and L Leydesdoff. Result also shows upward trend of keyword usage with an average of 4.55 per items, of which h-index, citation analysis, bibliometrics, g-index, etc, expectedly predominates. Scholarly nature of source journal has been further ascertained from increasing citations and reference usage trend. Moreover, growing hardness of the field has been attributed to JOI due to the increasing usage of tables and figures. Study also showed that the journal takes an average of about four month time to publish a manuscript.


Little is known about factors that could potentially affect burnout levels in teachers working with children diagnosed with Autism Spectrum Disorder. The aim of the study was to investigate burnout syndrome among teachers working with children with autism and to investigate how coping styles, supervisor support and workload are related to burnout. Sixty-five teachers in New South Wales Australia participated in a questionnaire study focused on their reports of burnout, work demands, supervisor support and the use of different coping strategies. Results showed that over eighty percent of teachers teaching children with autism in this study were experiencing moderate to high levels of emotional exhaustion. Results from hierarchical regression analyses indicated that the three components of burnout were associated with different factors; excessive work demands and the use of avoidance coping strategies played a central role in the prediction of increased burnout; on the other hand, the satisfactory level of supervisor support predicts the decrease in teacher burnout. Implications of this study include the importance of providing effective and appropriate supervision for staff, and for teachers to avoid the use of avoidance coping strategies, and for schools and education policy makers to improve working condition for teachers.


The key objective of this paper is to monitor the data and control the data regularly. By using a technology like PC Based Wireless process the real time data acquisition wirelessly using Supervisory Control and Data Acquisition. In large industries several processes are carried on regularly, so there is a necessity to observe all the processes and govern the factors affecting the process for that we can use this paper. In that different sensors i.e Humidity ,moisture, Temperature, Rainfall sensors are interfaced to the AT89S52 microcontroller. Information collected from the sensors is continuously sent over 2.4GHz trans-receiver wirelessly to the microcontroller which is then received at the corresponding 2.4 GHz USB type trans-receiver connected to a PC / Laptop. We can customize parameters like set point, lower limit and higher limit on the SCADA screen. As the different sensor goes below set point the microcontroller issues command to the respective relay. Higher limit and lower limit features are present for producing an alarm on the PC in the event of breakdown of system. Therefore, processes at dangerous places can be controlled with good accuracy by using wireless device to monitor the parameters so that we can take certain steps even in worst case. Few years back the use of wireless device was very less, but due the rapid development is technology now a days we use maximum of our data transfer through wireless like wi-fi, Bluetooth, wi max,etc.

Based on the method shown by nature the communication methods, that mankind uses today in many different ways, are obtained through science using the sixth sense of man. From the time when caves were used as homes to today when we are exploring ways of living in the sky, communication has been the basic need of mankind. During the Sangam era, there was a practise of announcing news by playing Murushu (drum). Based on this, it is known that the Tamils acquired the ideas of the elements of public communication in the Sangam period itself. In the classical period, there was a sharing of internal and external life messages. This article aims to examine how communication has played a role in the changes in life in the contemporary environment from then to today.


As existing tire models were no longer appropriate for vibration analysis of mechanical elastic wheel( MEW),elastic rope model was presented based on MEW's structural characteristics and its hinges' feature that transmitted force by single-direction. The single and total stiffness expression and frequency response function of the model were deduced and a complete mathematical model of MEW for vibration analysis was established. According to the model vibration, calculation under C-level random rough road input was conducted,and the center displacement response of wheel hub in time domain and power spectral density response in frequency domain were obtained. By comparing the finite element simulation results, the correctness of the elastic rope model is verified and it indicates the resonant frequencies are 19 Hz ~ 21 Hz that provides a reference for the optimization of the MEW design.


Selenides of La, Er, and Y and tellurides of La, Er, Gd, and Y were prepared by direct reaction of the elements. Measured electrical characteristics indicate semiconducting behavior, with the possibility that a wide range of properties can be obtained within these series of rare earth compounds. Observed room-temperature resistivities, for example, ranged from about 10/sup -4/ ohm-cm for La/sub 2/Te/sub 3/ and ErSe to the insulator range for Y/sub 2/Se/sub 3/. All the compounds prepared possess high melting points (1400 deg -2000 deg C) and exhibit good thermal stability. The dissociation pressure of Gd/sub 2/Te/sub 3/ at its melting point appears to be as low as 0.01 atm. (auth)


The use of electronics and Flexible AC transmission devices in the power system solved a lot of problems with flexibility and improved power transmission capability. In the same time it also raised various power quality problems to the system. Hence it is of essence to analyse the power quality problems and classify them in order to take necessary steps to eradicate those problem and improve the power quality. The method proposed for power quality problem is analysed by Empirical Decomposition. Then Hilbert Transform is applied on the intrinsic mode functions. Thereby the characters can be extracted from the IMF-H transform of the signal which is classified by the proposed neural network and the classifiers. Here probabilistic neural network, Support vector machine and Fuzzy Classifier are used for the classification purpose. Similarly the Stockwell Transform of the signal is found out and various features can be extracted from the signal.

New Thesis on Sea Defence ,authored by Xi Li ha(音译),a Greman,perhaps is the first foreign military theoretical work introduced to China in modern age.Since the content of this book fits the need of Chinese building up their sea defence,so it drew attention of a few officials.In their discussion of sea defence,on the one hand they took the lessons of passive defeat in the First and Second Opium Wars,on the other hand accepted Xi Li Ha's concept of sea defence,put forth a comparative advanced plan for sea defense reconstruction.Despite no consensus was reached at last,we still should confirm the positive impact of the New Thesis on Sea Defence in modern China.


This retrospective study demonstrates that the obesity paradox applies to patients receiving CAR T-cell therapy and that sarcopenia can exert long-lasting adverse effects on treatment responses. The data highlight use of immuno-nutritional scores could aid in patient risk-stratification.


Abstract The available studies in France showed a paradox among North African migrant men in France and some other developed countries, i.e., that migration could have a protective effect against some nutrition-related noncommunicable diseases compared to French. The origin of this paradox is not well documented. Particular attention was given to the influence of socio-cultural and environmental factors on health status of North African migrants. Conservation of healthy diet habits, lower prevalence of smoking, lower alcohol consumption, and adoption of a more active lifestyle may confer protective effects on morbidity and mortality of North African men compared to local-born French. It should be noted however that beneficial effects of migration in men would be expected to decrease with the length of stay in the host country because of acculturation to the host country lifestyle. More comprehensive and larger-scale studies will be required to provide a better insight into migration-health relationships.


ISSUE ADDRESSED
Low health literacy disproportionately affects adults from culturally and linguistically-diverse backgrounds. This study investigated the health literacy of adults attending outpatient allied health services in western Sydney; a highly diverse region in Sydney with residents from a range of cultural and linguistic backgrounds.

METHODS
A cross-sectional survey was undertaken between March and April 2017 using the Health Literacy Questionnaire (HLQ). Participants, aged over 18 years and with a primary language of English, Arabic, Chinese or Hindi, were recruited from outpatient allied health clinics at (study hospital). Means (standard deviation) for each of the nine HLQ domains were calculated and associations with demographic variables were investigated using analysis of variance (ANOVA).

RESULTS
Two hundred and thirty people were included with mean age of 45.1 years (SD=19.0), the majority were female (75.5%), over half were born overseas (55.7%), and 77.6% reported speaking English at home. The highest mean score on a HLQ domain (out of 5) was 'Understanding health information well enough to know what to do' (M=4.19; SD=0.67), and the lowest mean score (out of 4) was 'Appraisal of health information' (M=2.97; SD=0.54). Participants who did not speak English at home had significantly lower scores on seven of the nine HLQ domains.

CONCLUSIONS
Important health literacy strengths and limitations of a diverse sample of adults attending outpatient allied health services in western Sydney were identified. Findings should be considered in light of the cross-sectional survey methodology with non-random sampling.

SO WHAT
Data will inform future interventions to improve health literacy and health outcomes among vulnerable population groups in western Sydney.


With the further readjustment of economic structure and set - up of production, in the process of speeding up urbanization and industrialization, large numbers of surplus rural workers leave their own hometowns for the big cities and are engaged in industrial. They have been already a major component part of the industrial workers group, however, quite a lot of them have being aloof from the trade union organization. Therefore, it is an urgent task to organize them and safeguard their legitimate rights and interests.

We find that if two superconducting islands of different number parity are linked by a tunnel junction the unpaired electron in the odd island has a tendency to tunnel into the even island. This process leads to fluctuations in time of the number parity of each island, giving rise to a random telegraph noise spectrum with a characteristic frequency that has an unusual temperature dependence. This new phenomenon should be observable in a Cooper-pair pump and similar single-electron tunneling devices.


The purpose of this study is to evaluate the effects of runoff control by green infrastructures in densely urbanized residential areas in the Greater Tokyo Area (GTA) in order to reduce the risk of urban flooding. In this research, we make comparisons of the effects of runoff control between green infrastructure and the measures projected by the Tokyo metropolitan government, which are composed of a mixture of porous pavement, seepage pit, and trenches for infiltration. This paper reveals that a green infrastructure plan gives feasible measures considering land use conditions, but is inferior to that of a seepage pit and soakage trench plan in terms of the total essential site area and the required expense. However, theoretically, the expense of the green infrastructure is improved by creating incentives for residents.


Extubation failure in premature infants is common. A spontaneous breathing trial (SBT) was prospectively evaluated to determine timing of extubation. Compared with historical controls, infants were extubated at significantly higher ventilator rates and airway pressures using the SBT. No differences in rates of bronchopulmonary dysplasia or duration of ventilation were seen.


Combining ab initio computations with a probabilistic rate approach, we investigate the bond-rotation mode of plastic yield in boron nitride nanotubes to predict the kinetic and thermodynamic strength. Relative to carbon nanotubes, the boron nitride yield defects have lower activation but higher formation energies. This leads to an interesting phenomenon of strength crossover for these two important materials under different conditions: at moderate temperatures carbon is stronger, while at high temperatures (or extremely long times) the situation is reversed and boron nitride is more stable thermomechanically.

This paper describes the resonance characteristics of two types of commonly-used electric power steering motors: the 8-pole-12-slot and the 10-pole-12-slot motor. The relationship between the excitation modes and characteristic vibrational modes is clarified by conducting a coupled magnetic field structural analysis and carrying out a modal analysis on a prototype. Finally, the 8-pole-12-slot and 10-pole-12-slot motors are compared in terms of their generated noise.


At present, performance holds a key position in the success of software systems. However, quite a number of software products do not meet the performance requirements from the beginning. One of the best way to solve this problem is to introduce a software performance evaluation mechanism into the software development life cycle through modeling and simulation. The Unified Modeling Language (UML) and PetriNet Queueing (QPN) specification languages have a number of advantages in evaluating software performance parameters. Therefore, transform from UML to QPN model is considered as one of the most effective ways to solve software performance evaluation problems. However, this transformation is very difficult because the difference between the semantic of models. In this paper, we propose an approach based on modular transformation, provides an intermediate model consisting of abstract modules from elements in UML and QPN according to function and structure. The transformation consists of three steps: Extending the UML model to the XMI model, converting this model to the XML format of QPN. Transformed QPN models can work correctly and provide a framework for evaluating software performance against the Queueing Petri net Modeling Environment (QPME) tool.

The relationship between residential property values and nonconforming land uses is of interest to real estate academicians and practitioners alike. For some time, urban economists have tried to measure the negative externality costs and the amenity benefits associated with nonresidential land uses. Urban planners and city officials have also been concerned with the relationship between nonconforming land uses and the potential for visual intrusion, increased traffic congestion, and other negative externalities. Indeed, the potential for negative externalities has often been cited in public hearings and municipal planning departments as a primary reason for the establishment of zoning districts. Such public debates are frequently fueled more by emotion and misinformation than they are by statistical evidence. City officials in Dallas, Texas, for example, recently agreed to make land-use regulations more restrictive partially in response to homeowners' complaints that high-rise office buildings have a significant negative impact on nearby residential property values. The prior cumulative zoning ordinance' permitted high-rise buildings (of up to eleven stories) in districts zoned for shopping centers (which are typically less than three stories). The new zoning law prohibits high-rise office properties in shopping center districts. This paper employs the hedonic estimation technique to estimate the effect that one high-rise office building has had on the value of nearby houses in a small residential area of North Dallas. In 1980, construction was completed on an eleven-story,


To observe the effect to optimizing the immunization schedule for the DNA vaccine and vaccine of prepared by the co-expression of HIV-1 gag and IFN α-2b gene,the plasmid pJ38 gag/IFNα-2b genes were transfected to RK cells under the mediation of liposomes,and the expressed product was identified by indirect immunofluorescence method and dot-ELISA.This product was used to immunize mice combined with DNA vaccine,and the effect was evaluated by lymphocyte transformation test,counting of CD+ 4,CD+ 8T cells and CTLs as well as the determination of humoral immunity levels,It was found that the particulate antigen prepared by the co-expression of the PJ38 gag/IFN α-2b genes showed good immunogenicity and the effect of optimizing the combined use of one dose of PJ38 gag/IFN α-2b vaccine plus one dose of DNA vaccine was better than that of the use of VJ38 gag/IFN α-2b vaccine alone.It concludes that the particulate antigen prepared from the co-expression of vJ38 gag and IFN α-2b can induce the production of cellular and humoral immune responses.


With the extending application and increasing request of the aviation remote-sensing, the question how to broaden the field of view of aviation remote-sensing camera shooting becomes attention more and more. One important method to extend FOV is to change the shooting mode of aviation remote-sensing camera. The aviation swaying camera changes the immobile shooting mode to the mobile shooting mode, so in one shooting spot an aviation swaying image set, whose imaging planes are not same but whose part regions overlap, can be obtained. By stitching the aviation swaying image set, the image which possesses the larger FOV can be obtained. In the paper, the swaying model of the aviation swaying camera was studied, and based on the model a registration and stitching algorithm of the aviation swaying image set was proposed. The experiment result shows that the registration and stitching algorithm can stitch the aviation swaying image set smoothly.


The invention relates to the field of cutting machining of building materials and polymer composites, and particularly discloses a diamond saw blade capable of producing air holes in cutting. In a method for machining the diamond saw blade, particulate air hole materials which are carbonized in the hot pressing sintering of a tool bit are mixed with powder for producing the tool bit according to proportion, a blank is produced in a cold pressing way, the tool bit is produced in a hot pressing sintering way, the air hole materials are carbonized simultaneously, and in the cutting, the carbon particles are easy to abrade and drop to form the air holes. The diamond saw blade is used for cutting ceramic tiles, marbles, limestone and certain polymer composites. The air holes produced in the cutting increase a chip space and avoid the working surface of the tool bit being blocked by chips, thereby increasing the cutting speed, keeping the cutting quality and overcoming the shortcomings of broken edges, broken corners and the like.

This report collates the motorcycle safety aspects which came up during several days of an overseas study journey in January 1978, and is substantially extended by embodying in the text much of the material subsequently collected by or sent on to the author. The subjects covered include motorcycle dynamics, wet weather and antilock braking, accident analysis, education, training, licencing, legislation, motorcycle visibility, helmet performance, helmet and visor standards, U.S. Motorcycle and moped legislation, and moped issues. This approach has been adopted due to the scattered and inaccessible nature of many of the sources, and the consequent value of a reasonably broad and up-to-date coverage of the material and findings in context. The sections of this report concerned specifically with visors and helmets have already been drawn upon in connection with standards issues. /TRRL/


In this article, the authors investigate, from an interdisciplinary perspective, possible ethical implications of the presence of ubiquitous computing systems in human perception/action. The term ubiquitous computing is used to characterize information-processing capacity from computers that are available everywhere and all the time, integrated into everyday objects and activities. The contrast in approach to aspects of ubiquitous computing between traditional considerations of ethical issues and the Ecological Philosophy view concerning its possible consequences in the context of perception/action are the underlying themes of this paper. The focus is on an analysis of how the generalized dissemination of microprocessors in embedded systems, commanded by a ubiquitous computing system, can affect the behaviour of people considered as embodied embedded agents.

ABSTRACT Post-democratic South Africa continues to experience migrancy to large urban centres such as Johannesburg. One understudied group of migrants are women from the KwaBhaca region in the Eastern Cape. Many amaBhaca women are entrapped in Johannesburg because of the exorbitant costs required to return home, and they are increasingly isolated from their 'home' communities. Some women have formed dance groups that perform mamtiseni to mitigate the effects of urban entrapment. Through the life histories of these women and the performances by two mamtiseni dance groups, we can see how the dance has aided these women in navigating their everyday lives. Mamtiseni is used to build and strengthen networks, preserve a sense of 'Bhaca' community and culture, socialise the youth, reshape the urban space, and represent home in a foreign space. This study adds to the limited amaBhaca historiography and contributes to an understanding of how marginalised migrants use performance to shape and reinforce identity.
