In its early decades as a self-identified field of study, ethnomusicology (following in the footsteps of cultural anthropology) championed musical traditions in their indigenous (or at least longstanding) contexts, but diasporic musics were hardly excluded. Scholars as different as Alan Lomax and Charles Keil wrote extensively about Afro-American musics; studies of more recent immigrant communities dotted the pages of major journals; a series of edited collections (Nettl 1978; Porter 1978; Jairazbhoy and DeVale 1984) brought the study of ethnic communities in North America to the forefront; and, of course, the "marginal survival" of ballads from the British Isles preserved in Appalachia had been at the center of earlier studies in folk music. In 1991, the journal Diaspora: A Journal of Transnational Studies came into being. Editor Khachig Toloyan's introductory essay included the following oftquoted statement:


Prevention of obesity is one of the largest public health challenges faced by many societies today. At the most basic level obesity can be considered to result from behaviours that lead to an energy surplus. Although it is undeniable that genetic factors are contributing to development of obesity, data from international comparisons of prevalence of obesity indicate that environmental factors, such as physical, economic, political and socio-cultural factors, are also of major importance. The purpose of this article is to report on the Obesity Prevention Satellite meeting sponsored by the EASO Public Health and Prevention Task Force in 2010. This was the 4th Prevention Satellite to be organised in association with an ECO or ICO, following Stockholm 2003, Geelong 2006, and Amsterdam 2009. During that period there has been increased recognition that obesity prevention should take a multi-disciplinary, multi-sectoral, and settings-based approach. It has also become clear from the prevention satellites that many interventions to prevent obesity have limited effect. Often participation rates in interventions are low, and any effects achieved tend to dissipate once the intervention is completed. Morover it is apparent that the need for obesity prevention is highest in groups with relatively low socio-economic (SES) backgrounds. Decreasing the prevalence of obesity amongst these groups is a necessary step in reducing health inequalities. Unfortunately, engaging low SES populations in interventions is a challenge; even interventions that attain sufficient participation report rates that are lower amongst low SES individuals. In order to be effective, interventions need to be systematically planned and based on information regarding the determinants of behaviour, the SES, and socio-cultural contexts. They also need to make use of effective strategies for recruitment of and implementation within specific target groups. These perspectives formed the stimulus and background to the pre-congress meeting organised jointly by the Karolinska Institute and the EASO Prevention Task Force. The aim was to bring together a broad number of perspectives on obesity prevention in order to discuss how we could improve longterm obesity prevention strategies, especially when targeting low SES groups. This paper reports on the satellite's proceedings which comprised invited presentations, short presentations, and posters. The report focuses on the oral presentations; information on all presentations is available in the abstract book on the EASO homepage at www.easoobesity.org/ task_forces/prevention_satellite.htm.


We present a detailed network model of neurons of the cochlear nucleus to explore leveldependent processing by T stellate cells. These cells selectively process input from two types of auditory nerve fibres to enhance their dynamic range. We use a biologically plausible network between T stellate, D stellate and tuberculoventral cells, to show how level-dependent selective processing can be used to recreate rate-level curves seen in vivoand encode the spectrum of the vowel /ε/. The compartmental models include recently formulated current models of ventral cochlear nucleus cells to give greater accuracy of cell spiking behaviour.


Abstract Objective: To compare vitamin C level in term pregnant women with PROM and in women with normal pregnancy. Method: This is a cross sectional study, research from July 2010 until June 2011. Inclusion criteria are full term pregnant women with and without PROM. After the diagnosis is confirmed as PROM, mothers blood was taken from mediana cubiti venous to check the vitamin C level and leucocytes in mothers serum. Pregnancy with complication is the exclusion criteria. Result: There were 52 subjects that fulfilled the acceptance and rejection criteria after divided into 2 groups, the 1st group was with PROM and the 2nd groups were normal. Based on the laboratory examinations, the mean of vitamin C levels in PROM groups is 0.731 ± 0.182 μg/dl and the normal groups is 0.722 ± 0.169 μg/dl, there is no significant difference (p=0.852). Leucocyte examination was done to know whether there was infection or not. The mean value from the PROM groups is 14330.77 ± 6552.90 μg/dl. And from the normal groups is 12973.08 ± 4160.24 μg/dl, there is significant difference (p=0.377). Conclusion: There is no significant difference of Vitamin C level between maternal plasma with PROM and the one without PROM.

The goal of the control strategy for three-phase Pulse Width Modulation (PWM) rectifiers operating under unbalanced voltage conditions is to avoid ripple in the DC-link voltage and harmonics in the input AC currents. A stationary frame control scheme which regulates the instantaneous active power at the converter poles for minimizing of input/output harmonics is used. The design of the control loops involved in this control strategy is provided in this paper. Furthermore, a dynamic analysis of the PWM rectifier operating under balanced and unbalanced voltage operating conditions is performed. The analysis is supported by experimental results for a 20 kVA PWM rectifier prototype. Fast dynamic performance with small DC-link voltage ripple and input sinusoidal currents are obtained with this control scheme even under severe voltage dips operating conditions.


Control of unidirectional three-phase Vienna rectifier as Power Factor Corrector is relatively simple in the Continuous Conduction Mode. However, peculiar issues arise in the transition to Discontinuous Conduction Mode, resulting in lower regulation performance (e.g. higher Total Harmonic Distortion). To solve this problem, open-loop current control techniques have been recently proposed, which strongly rely on the voltage sensing for achieving accurate control of input current. Moreover, the phase of grid voltage needs to be known with high accuracy, for imposing the correct power factor. In this paper, the effects of poor voltage sensing (e.g. when using a low-cost transformer) on the current distortion and on Power Factor are considered. In order to overcome these issues, while keeping the cost low, a phase-shift compensation method is proposed in this paper, which is based on a simple digital filter. Also, the most important parameter of the transformer transfer function is identified by means of a self-commissioning procedure, which requires no additional hardware and can be easily carried out in the field. Selected simulation and experimental results are reported to validate the proposal. It is worth to mention that the proposal may be applied also to other topologies, i.e. virtually to any grid-tied converter.


Feedlot cattle with lung lesions, associated with bovine respiratory disease (BRD], display a reduction in average daily gain (ADG) compared to cattle without lung lesions. However, a moderate degree of variability in prevalence and ADG reduction has been observed in peer-reviewed literature; therefore, the true economic impact of lung lesions in feedlot cattle populations is unknown. The study objective was to estimate and compare the relative economic value between feedlot cattle with and without lung lesions through stochastic modeling methods. The model commenced at animal purchase and upon pen placement. Within each pen, cattle with and without lung lesions were modeled in parallel throughout the feeding phase, incorporating all production expenses and revenue. The final outcome was the difference in economic value between both cohorts when marketed on a live-weight basis. Based upon the assumption of this model, cattle with lung lesions lose, on average, $38.69 (90% probability interval: $12.28 to $79.32] compared to cattle without lung lesions. The reduction in ADG among cattle with lung lesions was a major driver in these outcomes supporting the findings from prior studies. Improved BRD diagnostic and therapeutic modalities are necessary to reduce lung lesion prevalence and subsequent negative economic impacts to the feedlot industry.


Sir, Hydatid disease is an endemic zoonotic infestation caused by the larval form of Echinococcus species.[1,2] The most commonly afflicted organ is the liver but any tissue other than hair, nails and teeth may be involved.[3,4] Primary subcutaneous involvement is rare and in these cases, even with inflammatory signs, a painless mass is the usual presentation.[1,5] We describe a case of solitary subcutaneous hydatid cyst on the anterior aspect of the leg with clinical features of cellulitis.


Hongjiadu concrete face rockfill dam belongs to a kind of dams with their height of 200 m, so crack control technology for the dam's concrete facing slabs becomes an important research subject. The basic design consideration of the mix proportion of facing slab concrete for the rockfill dam was to put stress on the seepage prevention and crack control of concrete on condition of meeting stipulated design strength, durability and workability of concrete. Through extensive experimental demonstration, polyacrylic fiber and lightly sintered magnesia were added in concrete for crack control. Up to now, only 10 cracks have been found in the completed stage I concrete facing slabs, with their crack width less than 0.2 mm. The number of cracks are far less than that of other similar dams. The application of the technology of adding both polyacrylic fiber and lightly sintered magnesia in concrete played a remarkable role in crack control of concrete facing slabs.


Exact inference in Bayesian networks is NP-Hard. While many parallel algorithms have been proposed for this irregular problem, none have been shown to scale to even hundreds of processors. In this paper, we present a scalable distributed-memory parallel algorithm for exact inference based on Darwiche's approach, which poses inference as upward and downward accumulation of values computed at the nodes of an arithmetic circuit, a rooted directed acyclic graph. Our work includes parallel algorithms for both construction of the arithmetic circuit as well as inference using the circuit. We demonstrate the scalability of our algorithms for up to 1,536 cores on synthetic as well as real datasets, whose corresponding arithmetic circuits contain up to billions of nodes. The runtime for inference is only a small fraction of the runtime for circuit construction, providing the ability to quickly perform multiple inferences once the circuit is constructed.


The relationship between childhood overweight and acculturation has previously been found to be positively related. However, with the prevalence rates of childhood overweight increasing globally, this relationship may no longer be observable. The purpose of this analysis was to test the association of acculturation and probability of overweight among a diverse sample of early adolescent girls over a 22 month time frame. Using the sample population from the Adequate Calcium Today, a multi‐state calcium intervention in early adolescent girls, weights and heights were measured 3 times. We conducted Kaplan‐Meier survival analysis on time to overweight (≥ 85th pctl according to the 2000 Centers for Disease Control and Prevention growth charts) and level of acculturation as exposure (individual indicators of generation and language spoken in the home) by Asian, Hispanic, or non‐Hispanic white early adolescent girls. There was no significant association between acculturation levels and time to overweight and obese in any of the race/ethnic groups. There was a significant association between survival (overweight‐free) and the race/ethnic groups (Log‐rank chi‐square=10.661, df=2, p=.005) with Asians girls having the highest survival and Hispanic girls the lowest survival. These results among early adolescent girls suggest that acculturation issues may not be as apparent in this era of a global obesity epidemic.


Hydrogen energy is a critical component of a sustainable and secure energy future, as well as an important development direction of the global energy technology revolution. Accelerating the development of the hydrogen energy industry can help not only to deal with the global environmental crisis, but also to ensure energy supply and achieve sustainable national energy development. By the end of 2021, there had been more than 10 provincial and municipal hydrogen energy industry plans, as well as more than 30 regional and county hydrogen energy special plans, and the central and local governments at all levels issued policies to promote the increase of hydrogen density, as well as further increased subsidies. Foran Energy is one of many companies making the switch to hydrogen. This article will be based on Foran Energy's data for the first half of 2022, combining the surrounding environmental situation to solve the phenomenon of low profit margins following Foran Energy's transformation. The study found that the company can improve its profit margin by adapting to the world situation and adjusting its development strategy.


One's style of communicating is vitally important to both the message being sent as well as to the message being received. We have often heard that how something is said is far more important than what actually was said. With this in mind, this piece deals with the essence of stylistic communication and this type of communication in proffering a second opinion. There are many reasons that people seek second opinions just as there are many reasons why doctors offer them. These reasons will be discussed in detail. This article will go into a detailed protocol for how to offer a second opinion. There are 3 types of second opinions that will be discussed. The first is the pre-treatment consultation. The second is the mid-treatment second opinion. The final one is the second opinion offered when one is acting as an expert witness. The offering of a second opinion is an art that needs to be studied and when expressed is truly a communications masterpiece.


Hydrogen storage in the form of a liquid chemical is an important issue that can bridge the gap between sustainable hydrogen production and utilization with a fuel cell, which is one of the essential sectors in the hydrogen economy. Herein, the application of a potential liquid organic hydrogen carrier, consisting of biphenyl and diphenylmethane, is demonstrated as a safe and economical hydrogen storage material. The presented material is capable of a reversible storage and release of molecular hydrogen with 6.9 wt % and 60 g-H2 L–1 of gravimetric and volumetric hydrogen storage capacities, respectively, presenting superior properties as a hydrogen carrier. Equilibrium conversion and the required enthalpies of dehydrogenation are calculated using a density functional theory. Experimentally, dehydrogenation conversion of greater than 99% is achieved, producing molecular hydrogen with greater than 99.9% purity, with negligible side reactions; this is further confirmed by nuclear magnetic resonance spectrosc...


Linear sweep voltammetry, preparative electrolyses under a variety of experimental conditions, and trapping experiments have been used to explore the mechanism of the formation of the aldol 2-benzoyl-1-phenylpropanol by electrochemical reduction of {alpha}-bromopropiophenone in the presence of benzaldehyde and lanthanum bromide. The aldol condensation occurs by reaction of the free (lithio) enolate with a lanthanum bromide-benzaldehyde-tetrahydrofuran complex. Electrochemical reduction of the bromo ketone forms the Z enolate highly stereospecifically. The erythro aldol is formed stereoselectively initially, but the condensation is reversible, and the equilibrium mixture of aldols, containing mostly the threo isomer, is isolated from the electrolysis.


A critical analysis of the simple writing style which German writer Hermann Hesse uses to write his novel 'Magister Ludi', even though he uses the background of an epic to produce his Utopia. It is compared with a Utopian novel 'Tomorrow and Tomorrow' written by Australian M. Barnard Eldershaw. The author argues that Hesse writes with more grace than Eldershawl.


of the blood may determine not only the immediate outcome of the operation but also the speed of the repair processes. The subject of wound healing may also be looked at in another way. What, for example, are the conditions that determine the breakdown or dehiscence of surgical wounds which might be expected to heal by first intention'? Sokolov2 has reviewed and analysed the factors in the disruption of abdominal wounds in 732 cases. This phenomenon was twice as common in men as in women, and commoner in the first half of the year than in the second (this was thought to be due to a lowering of the vitamin C content of the tissues); it occurred especially between the ages of 40 and 60, in association with emaciation, in the presence of malignant disease, or in association with operations on the stomach or intestinal tract; and, finally, the wounds which broke down were usually not infected. The figures quoted by Sokolov revealed that wound disruption took place in 2 to 3% of all abdominal cases. Other workers have arrived at similar results and conclusions, and all have stressed the fact that failure of the healing process is most likely to arise in patients suffering from gastro-intestinal disease. In reporting the post-mortem findings in a series of cases after partial gastrectomy Payne' stressed the fact that in a considerable proportion of these the fatal outcome was associated with an almost complete lack of response at the site of the anastomosis. Studley4 has also shown that the mortality in operations for peptic ulceration is directly proportional to the antecedent loss of weight. The general nutrition of the surgical patient is thus inseparably bound up not only with the immediate prognosis of the operation but also with the breakdown or dehiscence of the operative wounds, whether visceral or parietal. During recent years much work has been done on vitamin C in relation to the healing of wounds. Lanman and Ingalls5 demonstrated the importance of this in securing normal repair of experimental wounds in guinea-pigs, an observation that has now been confirmed and amplified in a recent paper by Hunt.6 These experimental studies show that collagen does not form in the healing wounds of guinea-pigs partially deficient in vitamin C; the proliferating mesodermal cells fail to mature, and the healing of the whole wound is profoundly disturbed. In a series of twenty-eight human cases investigated post mortem and reported by Hunt there was a comparable histological picture in eight, and in five there was disruption of the abdominal wound, and in three leakage at the gastro-intestinal suture line. It seems clear, therefore, that a subscurvy state leads to a gross disorganization of the whole orderly process of wound healing, and supports the view that the same deficiency may lead to failure of wound healing or even to wound disruption in human beings after surgical operations. This work has recently been confirmed by Fox7 in a paper on experimental human scurvy.


Due to various factors such as urban development, climate change, and tectonic movements, landslides are a common geological phenomenon in the Qinghai–Tibet Plateau region, especially on both sides of a road, where large landslide hazards often result in traffic disruptions and casualties. Identifying the spatial distribution of landslides and monitoring their stability are essential for predicting landslide occurrence and implementing prevention measures. In this study, taking the Kangding-Batang section of Shanghai-Nyalam Road as the study area, we adopted a semi-automated time-series interferometric synthetic aperture radar (InSAR) method to identify landslides and monitor their activity. A total of 446 Sentinel-1 ascending and descending SAR images from January 2018 to December 2021 were thus collected and processed by using open-source InSAR processing software. After a series of error corrections, we obtained surface deformation maps covering the study area, and a total of 236 potential landslides were subsequently identified and classified into three categories, namely slow-sliding rockslides, debris flows, and debris avalanches, by combining deformation maps, optical images, and a digital elevation model (DEM). For a typical landslide, we performed deformation decomposition and analyzed the relationship between its deformation and rainfall, revealing the contribution of rainfall to the landslide. In addition, we discussed the effect of SAR geometric distortion on landslide detection, highlighting the importance of joint ascending and descending observations in mountainous areas. We analyzed the controlling factors of landslide distribution and found that topographic conditions are still the dominant factor. Our results may be beneficial for road maintenance and disaster mitigation. Moreover, the entire processing is semi-automated based on open-source tools or software, which provides a paradigm for landslide-related studies in other mountainous regions of the world.


Particle-in-cell simulations of laser- ion acceleration demonstrate marked discrepancies in the acceleration experienced by the different ion species in complex target compositions, especially when the target becomes relativistically transparent to the pulse during irradiation. Beginning with proton contaminants in a carbon target, we show how the higher charge-to-mass ratio of the protons results in species stratification and late-time suppression of the carbon acceleration. The target normal sheath acceleration (TNSA) primarily experienced by the protons can be exploited to mitigate this tamping by using a shaped rear surface of the target, leaving the break-out afterburner-driven carbons to accelerate close to the laser axis and then experience less tamping during a late-time TNSA phase. We then explore preferentially accelerating the lighter species in a mixed composition target, particularly focusing on deuteron beam applications. We examine three different target compositions with the same areal electron density, CD2, CH2, and 7LiD, and propose an alternative shaping of the rear surface of 7LiD to increase the number of high-energy deuterons in the beam.Particle-in-cell simulations of laser- ion acceleration demonstrate marked discrepancies in the acceleration experienced by the different ion species in complex target compositions, especially when the target becomes relativistically transparent to the pulse during irradiation.

A preliminary numerical study has been conducted to study the effect of rotational speed on centrifugal growth in a six-tooth straight labyrinth seal. The distribution of the radial deformation along the seal axis for the rotational speed ranging from 100 rpm to 1500 rpm is reported in this paper. The radial deformation which decreases the clearance between the rotating and stationary parts of sealing surface is an indication that centrifugal growth occurs. The results of the simulation indicate that centrifugal growth increases as rotational speed increases. This finding is in qualitative agreement with other numerical and experimental work reported in the literature.


Fractal Geometry is the key for creating eye soothing and distressing spaces due to its Psychological effects on human brain. From the heart beats to the entire galaxies, fractal geometry is everywhere. The nature sustainability and processes are all designed and planned in a rhythmic harmony that God created in form of fractals. Motivated Perception is a phenomenon which simply means the way we see the world. Our perception is often biased, selective, and malleable similarly our mind needs something which creates interest .Efficient learning in today era needs technology as a main source for which the learning is bounded to the structure based spaces having roof over it and having digital gadgets for more mind growth of learning individual with more exposure for creating interest leading to loss of connection of learning individuals from nature feelings and senses.The primary school will be best implication of fractal design. Based on these factors why not to bring the fractals as design elements in the primary school as fractal designed spaces by nature replicating processes which gives senses as same as nature without real nature inside the space. Fractal Designed school would be a space where learner could learn without any sort of boredom and get relaxation vibes always.


This study investigates the impact of office technology management on university business education programs. Business education is an essential component of Vocational Education in Nigeria's tertiary education system. Reforms in the nation's education delivery have resulted in a jumble of programs requiring the use of new technologies. As a result, the impact of office technologies on business education is a major theme. When the influence is positive, it indicates that the goal of integration is worthwhile; when it is negative, it indicates that there is a serious problem that necessitates some action. Because education is now centered on office technologies all over the world, business education cannot afford to ignore the significance of utilizing office technologies. As a result of their findings, the researchers concluded that a worthwhile business education curriculum should provide learning experiences that will equip lecturers and staff with the necessary competencies in the use of office technology, and students should be trained to meet the market demands of various occupations. It was suggested that business educators give their students an experiential foundation so that they can develop the necessary competencies.


Abstract Herein is disclosed a novel visible-light photocatalytic double C–H functionalization of indoles. The reaction affords 2,3-difunctionalized indoles in up to 84% yield, but the reaction rate depends strongly on electronic substituent effects. Mechanistic DFT studies and control experiments suggest that the secondary functionalization occurs through an independent photocatalytic oxidation of bromide ions formed during the reaction to generate molecular bromine capable of electrophilic C-3 bromination.


Abstract
Most male individuals of all species of the genus Scarus which were reversed from females, are called âsecondary malesâ. However, a few individuals of âprimary malesâ would have maleâs reproductive ability, but never process sex reversal in their lifespan, and keeping femaleâs outlook (initial phase). Because parrotfishes have these two kinds of males existing in the same species, they belong to âdiandryâ protogynous hermaphroditisms. Previous studies suggested that the mechanisms that cause primary male might be due to social effect or genetic control. In our experiments, Blue barred parrotfish (Scarus ghobban) and rivulated parrotfish (Scarus rivulatus) were used to study the sex reversal model of parrotfish and the possible reasons that cause the juveniles develop to be primary males. This study including three major parts: (1) the relationship between body size and sexual types of two species. (2) the comparison of the tissue structures of the testes in both male types by histological observation. (3) the possible karyotypes difference, i.e. the genetic differences between primary and secondary male. This study shown that the body size of blue barred parrotfish (initial phase: 100-475 mm; terminal phase: 275-525 mm) were larger than rivulated parrotfish (initial phase: 126-270 mm; terminal phase: 246-350 mm), and there was a wider overlap zone between both color phases in Blue Barred parrotfish (S. ghobban: 47.2%, then S. rivulatus: 10.7%). Histological results showed that no matter primary or secondary males, they all had classical lobular testes. But, by contrast of the pure testis tissue of primary male, there were many mature or atric oocytes that remained in the testis of secondary male. Additionally, a few secondary males of the blue barred parrotfish were discovered whose process of sex reversal occurred earlier or faster than that for normal secondary males. Histological evidence further suggested that these individuals had never had a female reproductive function. Furthermore, these males which had no difference with other secondary males was found on the chromosome level. In our study, a heteromorphic chromosome was observed between primary males and secondary males of the rivulated parrotfish (Scarus rivulatus), which could prove that being a primary male is predetermined by a genetic factor. Based on the ecological interactive diversity of the two species, a preliminary hypothesis was put forth to explain those phenomena. Due to the spawning tactics used, the proportion of primary males in rivulated parrotfish populations is much higher than that in blue-barred parrotfish populations. On the other hand, the appearance of premature males was suggested to be a way of supplying sperm which was lacking in the population of the blue-barred parrotfish.


A gold-catalyzed synthesis of cyclic 2-oxodienes from readily prepared propargyl alcohols and the subsequent Diels-Alder reaction are reported. The dehydrative cyclization reactions proceeded smoothly, and the dienes formed in situ were demonstrated to undergo cycloaddition with a variety of dienophiles. This method offers a new strategy for the synthesis of indolocarbazole alkaloids, whereby the convergent synthetic design allows for differentiation between the indole nitrogens.


: Automation plays a major role in Spacecraft integration and testing activities. Checkout software is used for the automation of Spacecraft Checkout operations in which Test files are generated in-prior for execution and one by one it is validated and stored and when required it will be retrieved and required modification is done based on the type of testing and its requirement. In the automated scenario of Spacecraft testing, for a faster checkout operation, test schedules can be generated by logically grouping test procedures of a spacecraft subsystem in advance and submitted for execution which reduces manpower requirements and minimizes testing time. This paper discusses on Test Schedule Generator and Executor. Test Schedule Generator and Executor is a GUI based application which has two main functions. First part is an IDE is to create a Test Schedule files. Test Schedule files are written using a specific language called Checkout Schedule Language. Second major function is to execute the Test Schedules by interfacing with the Execution Engine of Checkout Software. An experimental result shows the comparison between old and new system based on time, Manpower, Software modules and Execution speed and shows that new system is better than old system.


Background: Lot Quality Assurance Sampling (LQAS), a tool used for monitoring health indicators in low resource settings resulting in "high" or "low" classifications, assumes that determination of the trait of interest is perfect. This is often not true for diagnostic tests, with imperfect sensitivity and specificity. Here, we develop Lot Quality Assurance Sampling for Imperfect Tests (LQAS-IMP) to address this issue and apply it to a COVID-19 serosurveillance study in Haiti. Development: As part of the standard LQAS procedure, the user specifies allowable classification errors for the system, which is defined by a sample size and decision rule. We show that when an imperfect diagnostic test is used, the classification errors are larger than specified. We derive a modified procedure, LQAS-IMP, that accounts for the sensitivity and specificity of a diagnostic test to yield correct classification errors. Application: At Zanmi Lasante health facilities in Haiti, the goal was to assess the prior circulation of COVID-19 among healthcare workers (HCWs) using a limited number of antibody tests. As the COVID-19 antibody tests were known to have imperfect diagnostic accuracy, we used the LQAS-IMP procedure to define valid systems for sampling at eleven hospitals in Haiti. Conclusions: The LQAS-IMP procedure accounts for imperfect sensitivity and specificity in system design; if the accuracy of a test is known, the use of LQAS-IMP extends LQAS to applications for indicators that are based on laboratory tests, such as COVID-19 antibodies.


springs and dampers to generate forces between the body and the wheels. Here we use a bond graph to study the control and the limitations of an actuator based on a rotary d.c. motor /generator and a gear system to convert from the relative velocity between the body and wheel to the angular velocity of the motor. The intention is to replace the conventional passive or semi-active dampers. An elementary sign changer and pulse width control scheme is included. The system can supply energy to the suspension system from an electrical battery but also can sometimes return energy to the battery when mechanical power is removed as the suspension reacts to roadway unevenness or rapid maneuvers. The bond graph incorporates a modulated transformer to represent a pulse width modulation device. The result is a four quadrant actuator which is analyzed for its short term steady state performance.

Although the use of the actuator results in a type of active suspension, the retention of a an energy conservative springing system to counteract the large forces due to gravity means that, unlike some other fully active suspensions, a large source of power, is not required. At the same time, the actuator forces are not subjected to the limitation that passive and semi-active dampers are: namely that the sign of the forces generated is constrained by the sign of the instantaneous relative velocity across the device. This means that new control schemes can be explored for generating suspension forces to improve the ride and handling characteristics of the vehicle subject only to the limitations inherent in the actuator itself. A secondary benefit is the possible harvesting of energy during operation in regions of high generator efficiency.


Introduction: Blood samples collected on filter paper (dried blood spot [DBS]) is an immunoassay that has been used for antibodies screening. Objective: To evaluate the strategy of DBS blood collection for detection of HIV antibodies, evaluation of Q-Preven HIV 1 + 2 – DBS kit lot, and to analyze the stability of DBS samples. Method: Blood collection on DBS was performed according to World Health Organization (WHO) recommendations. The evaluation of the kit lot for HIV antibodies detection was performed using delta (d) values from the results of 774 DBS samples from volunteers men who have sex with men (MSM) recruited in the central region of Sao Paulo city, Brazil. Result: DBS blood collection was performed without complications. The positive (5.26) and negative (5.23) delta values allowed to clearly differentiate HIV antibodies reactive and non-reactive samples. We observed good performance of the kit lot and samples were stable on DBS form. Conclusion: Blood collection on DBS is feasible for the study of MSM population and is suitable for laboratory routine. The overall performance of Q Preven HIV-1 + 2 – DBS kit was satisfactory, having reached the quality levels required for the development of this study.


Port–hinterland container logistics transportation systems (PHCLTSs) are significant to economic and social development. However, various kinds of unconventional emergency events (UEEs), such as natural or human-caused disasters, threaten PHCLTSs. This study aims to measure and improve the resilience of PHCLTSs. Bi-level programming models with two different lower level models are established to help PHCLTSs recover their capacity efficiently in the face of UEEs. In the upper level model, the government makes immediate recovery decisions about a damaged PHCLTS with the goal of improving the resilience of the PHCLTS. In the lower level models, truck carriers make decisions about transportation routes and freight volume in the recovered PHCLTS. They cooperate fully to pursue the maximization of total profit and are coordinated by a central authority, or they make their own decisions to pursue maximization of their own profit noncooperatively. An algorithm combining particle swarm optimization (PSO) and traditional optimization algorithms is proposed to solve the bi-level programming models. The numerical experimental results show the validity of the proposed models.


As the existing complex number Nth root computation methods are relatively discrete, we propose a general method and architecture based on coordinate rotation digital computer (CORDIC) to compute arbitrary complex number Nth root for the first time. Our method performs the tasks of computing complex modulus, complex phase angle, real Nth root, sine function and cosine function, which can be implemented by circular CORDIC, linear CORDIC and hyperbolic CORDIC. Based on these CORDICs, our proposed architecture can not only improve the hardware efficiency just through shift-add operations, but also flexibly adjust the precision and the input range of complex number Nth root. To prove its feasibility, we conduct a software simulation and implement an example circuit in hardware. Under the TSMC 28nm CMOS technology, we synthesize it and get the report that it has the area of 6561μm2 and the power of 3.95mW at the frequency of 1.5GHz.


Information Communication Technology (ICT) is playing vital role in almost all the spheres of life and for the transparency and faster development of the nation. ICT is being utilized in the field of Teaching-Learning widely as one of the most important tool. Smart classroom based Teaching-Learning are now a days very common in the educational institutions which improves quality of education as well as quality of results. This paper explores utilization of ICT in the higher education and analyze the impact of utilization of ICT in learning process on students' perceptive. A questionnaire is developed for the purpose and data are collected from various higher educational institutions. Study is based on three different groups to see how these groups are different in terms of utilization of ICT in learning process. Three established hypothesis are based on Gender (Male and Female), Nature of institution (University and College) and Level of class (PG and UG). The hypothesis are tested using t-test and the results are found as per the expectation. Keywords— Information Communication Technology (ICT), Significant Difference, t-test Introduction


Lead(II) 2,9-dimethyl-1,10-phenanthroline complexes with anionic (L = 4,4,4-trifluoro-1-phenyl-1,3-butandionate (tfpb) and thenoyltrifluoroacetonate (ttfa)) ligands, [Pb2(dmp)2(μ-L)2(L)2], have been synthesized and characterized by elemental analysis and IR, 1H NMR, and 13C NMR spectroscopy. The single-crystal structures of the compounds show the coordination number of Pb(II) to be eight with two N-donor atoms from a "dmp" ligand and six O-donors from the anionic ligands. Self-assembly of these complexes is realized by C–H ··· F–C, C–F ··· F–C and π–π stacking interactions.


In Indonesia there are 59 white crystal sugarl mills which has beenwas operating since the Dutch period. Until now most of the existing plant of white sugar, are using sulfitation technology. The use of sulfitation technology will result with crystal color quality of 6.6 - 7.2 CT, the color of a solution of 118 - 201 IU and sulfur dioxide (SO2) content of 5 - 19.7 mg/kg. To improve the quality of the white sugar produced, PG. Semboro have tried to make changes of the process of cane sugar juice refining from sulfitation technology to defecation remelt carbonatation technology. The use of defecation remelt carbonatation technology can improve the quality of white sugar produced, i.e color crystal becomes 2.85 - 3.50 CT, clear white visually, solution color index of 43.3 - 80 IU and sulfur dioxide (SO2) of 0.76 - 1.33 mg/kg. As for the others parameters of both sulfitation and defecation remelt carbonatation technology there is no difference.


Much of the research that contributes to understanding how bilingual children become literate is not able to isolate the contribution of bilingualism to the discussion of literacy acquisition for these children. This article begins by identifying three areas of research that are relevant to examining literacy acquisition in bilinguals, explaining the contribution of each, and associating each type of research with a skill required by monolingual children in becoming literate. Three prerequisite skills for the acquisition of literacy are competence with the oral language, understanding of symbolic concepts of print, and establishment of metalinguistic awareness. A review of the literature explores the extent to which these skills that influence literacy acquisition in monolinguals develop differently for bilingual children. The conclusion is that the relation between bilingualism and the development of each of the three skills is different, sometimes indicating an advantage (concepts of print), sometimes a disadvantage (oral language competence), and sometimes little difference (metalinguistic concepts) for bilingual children. Therefore, bilingualism is clearly a factor in children's development of literacy, but the effect of that factor is neither simple nor unitary.

Since the publication of this article, our research has continued to explore the themes set out in this framework and provided more detail for the description of how bilingualism affects the acquisition of literacy. Two important advances in this research are the finding that some aspects of reading ability, notably phonological awareness, are rooted in general cognitive mechanisms and transfer easily across languages, whereas others, such as decoding, are more language dependent and language-specific and need to be relearned with each new writing system (Bialystok, Luk, & Kwan, 2005). Second, writing systems and the differences between them have a greater impact on children's acquisition of literacy than previously believed. Not surprisingly, this relation has been found for emerging ability with phonological awareness (Bialystok, McBride-Chang, & Luk, 2005) but, more surprisingly, has recently been shown to have a subtle influence on children's emerging concepts of print (Bialystok & Luk, in press).

The interpretation that bilingualism must be considered in terms of both advantages and disadvantages has also been pursued in studies of cognitive and linguistic processing in adults. Recent research has shown that adult bilinguals display disadvantages on tasks measuring lexical retrieval and fluency (Michael & Gollan, 2005) but advantages on tasks assessing cognitive control of attention (Bialystok, Craik, Klein, & Viswanathan, 2004). This approach leads to a more detailed and, ultimately, more accurate description of how bilingualism affects cognitive performance.

Purpose: To evaluate the reproducibility of a commercial Monte Carlo dose calculation algorithm for electron beams. The Varian electron Monte Carlo (eMC) dose calculation algorithm allows the user to specify the "accuracy" of the dose calculation. Because of the stochastic mature of the algorithm, one expects that correlations between successive calculations should be minimal. Method and Materials: The dose distribution (per monitor unit) in a flat water phantom was calculated for multiple field sizes, with and without inserts, for multiple energies. The dose grid voxel size was 2.5 mm in all directions, and smoothing of the dose distribution was turned off. The depth dose profile was extracted by averaging the dose matrix voxels in variably-sized rectangular regions centered on or near the beam axis. Depth dose distributions were compared for different regions in the same calculation and for the same region in different calculations. Results: The depth doses in adjacent CT slices showed significant correlations, as expected. An unexpected result was that the depth doses in slices with up to 2.5-cm separation also showed significant correlations. Also unexpected for higher energies was that the depth dose exhibited a systematic oscillatory behavior in the region near dose maximum that was not reduced even by averaging over a large area. Comparing the depth doses for different field sizes, the same correlations were seen. In addition, averaging the dose over multiple calculations of the same beam did not smooth out the apparent noise in the depth dose. Conclusion: The systematic uncertainties are approximately 1% and are most visible for higher energies because of the flat dose maximum region. The correlations seen in this work are most likely a result of complex interactions between the Monte Carlo step size and the dose grid, as well as possible reuse of particle histories.


During the Fascist regime millions of postcards circulated featuring Mussolini in many different guises and forms. This article reflects on their production, distribution and consumption and considers the extent to which they can be seen as part of the propaganda of a totalitarian regime. It also explores the meanings of the imagery of a selection of postcards. It argues that Mussolini postcards, despite their vast numbers, amounted in fact to only a small proportion of those circulating under the regime. Moreover, many of them were produced by private publishers for profit rather that Fascist organisations or the state. Therefore they cannot simply be considered as a manifestation of totalitarianism and must rather be conceived in large part as an effect of the impact of Mussolini on popular culture.


Abstract This contribution focuses on a dialogue model using an intelligent working memory that aims at facilitating a robust human-machine dialogue in written natural language. The model has been designed as the core of an information seeking dialogue application. The particularity of this project is to rely on the potent interpretation and behaviour capabilities of pragmatic knowledge. Within this framework, the designed dialogue model appears as a kind of 'forum' for various facets, impersonated by different models extracted from both intentional and structural approaches of conversation. The approach is based on assuming that multiple expertise is the key to flexibility and robustness. Also, an intelligent memory that keeps track of all events and links them together from as many angles as necessary is crucial for multiple expertise management. This idea is developed by presenting an intelligent dialogue history which is able to complement the wide coverage of the co-operating models. It is no longer a simple chronological record, but a communication area, common to all processes. We illustrate our topic through examples brought out from collected corpora.

TPS3133 Background: Dendritic cells (DC) are antigen presenting cells proficient in inducing de novo immune responses, and the presence of intratumoral DCs confers a survival advantage to patients, likely due to an improved balance between the immune system and the growing tumor lesion. We have initiated a Phase I/II clinical trial to exploit this finding, by using partially activated autologous DCs (aDC; DCVax-Direct) for intratumoral injection in inoperable tumors for which limited treatment options exist. These aDC retain antigen uptake and presentation capability and are conditioned to complete the maturation process following injection, resulting in initiation of a broad anti-tumor immune response. Preclinical animal data have demonstrated that these aDC can mobilize both local and systemic immune responses, and effectively clear both injected (local) and non-injected (distal) inoperable tumor lesions. Methods: The Phase I component of the trial aims to enroll 6 patients each in following indications...


Assess strengths and limitations of mixed bipolar depression definitions made more inclusive than that of the Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (DSM‐5) by requiring fewer than three 'non‐overlapping' mood elevation symptoms (NOMES).


The aim of this work was to study the effects of genotype and the indolbutyric acid (IBA) on the rooting of semi hardwood cuttings of peach rootstocks. This work was divided into Experiment 1, in which the 'Capdeboscq' and 'Nemaguard' cultivars was treated with four IBA concentrations (0; 1,000; 2,000 and 3,000 mg L), and a quadratic behavior was observed with near 50% of rooting in the estimated concentration of 2,500 mg L IBA, and a linear increase in the roots numbers occurred with increasing in IBA concentration, where 'Nemaguard' was more responsive than 'Capdeboscq'. In the Experiment 2, the 'Flordaguard', 'Hansen 2168', 'Kutoh', and 'Nagano Wild' were treated with two IBA concentrations (0 and 2,000 mg L) and the IBA treatment allowed to obtain higher rates of rooting, number of roots and root length in the four cultivars comparing to the control. 'Hansen 2168' showed the highest rooting percentage (72.5%). 'Floradaguard' and 'Hansen 2168' showed higher number of roots per cutting (9.9 and 8.5, respectively), and 'Nagano Wild' had the lowest number and length of roots per cutting (4.8 and 3.3 cm, respectively). It was concluded that exists synergistic interaction between the factors evaluated, but the IBA usage is essential for satisfactory rooting rates.


Ethical issues are fundamental in the planning and implementation of classroom research. This paper describes issues that arose as the researcher considered the ethical implications of a classroom research project studying teaching and learning issues in a grade 10 science classroom in Australia. Ethical issues were related to the relationships between the classroom teacher and her students, and between tl,e research team and the teacher-researcher. Three principles of utilitarian research ethics that can be applied to a research study were identified by D. Flinders (1992) as informed consent, avoidance of harm, and confidentiality. Reflection on the research resulted in the conclusion that these traditional ethics were not powerful enough to address all of the issues that emerged during this school-based study. The "professional ethics" defined by H. Sockett (1993) as "care, courage, honesty, fairness, and practical wisdom" provided a richer framework for the analysis of the relationships between the teacher and her students and the research team and the teacher-researcher. Care was apparent both in the caring relationship between the teacher and her students and in the caring relationships the research team developed with the teacher. The research team also displayed, at varying levels, the virtues of fairness, honesty, and practical wisdom. In addition, the teacher displayed these virtues in her interactions with students and the research team. (Contains 10 references.)

We report high-pressure (up to 50 MPa) ESR-spectroscopic investigations on the rotational correlation times of the nitroxide radicals 2,2,6,6-tetramethylpiperidine 1-oxyl (TEMPO), 4-hydroxy-2,2,6,6-tetramethylpiperidine 1-oxyl (TEMPOL), and 4-amino-2,2,6,6-tetramethylpiperidine 1-oxyl (ATEMPO) in the ionic liquids 1-ethyl-3-methylimidazolium tetrafluoroborate (emimBF4), 1-butyl-3-methylimidazolium hexafluorophosphate (bmimPF6), 1-butyl-3-methylimidazolium tetrafluoroborate (bmimBF4), 1-methyl-3-octylimidazolium tetrafluoroborate (omimBF4), and 1-methyl-3-octylimidazolium hexafluorophosphate (omimPF6). The activation volumes (38.5–56.6 Å3) determined from pressure dependent rotational diffusion coefficients agree well with the pressure dependent viscosities of the ionic liquids. Experimentally, the fractional exponent of the generalized Stokes–Einstein–Debye relation is found to be close to one.


This paper presents a generic scheme to extract traffic information from both optical satellite imagery and optical airborne image sequences. The extraction is based on an explicit semantic model of traffic, from which, depending on the characteristics of the input data, different strategies for vehicle detection, vehicle queue extraction and motion estimation are derived. The model comprises different scales to exploit the scale‐dependent properties of traffic imaged by optical sensors. It is furthermore extended by context information to include knowledge about background objects as well as metadata from a road database in a consistent way. Various tests with different input data have been carried out and compared with manually acquired ground truth data of vehicles and vehicle tracks. The results show clearly the high potential of airborne and spaceborne traffic monitoring, but also indicate room for methodological improvements and exhibit some inherent sensor‐related drawbacks.


Synopsis : The deterioration mechanism of polymer outdoors is known as autooxidation caused by radical chain reaction. Fluorocarbon resin is used to improve the weatherability of precoated metal (hereafter PCM). The binding energy and the hydohobicity of fluorocarobon resin are higher than those of other organic resins, therefore the generation of alkyl radical and the hydrolysis of bonding are reduced. We have investigated the improvement for the weatherability of acrylic base PCM without fluorocarbon. We have introduced hindered amine light stabilizers (hereafter HALS) to capture the radical, and introduced cyclohexyl metacrylate (hereafter CHMA) instead of styrene or methyl metacrylate to improve the light stability and hydrophobicity. HALS was copolymerized with CHMA to prevent the flow out form paint. The newly developed HALS-CHMA PCM showed not only good weatherbility but also good corrosion resistance.


Background—It is unclear what is the most efficient vector and growth factor for induction of therapeutic vascular growth in the heart. Furthermore, the histological nature of angiogenesis and potential side effects caused by different vascular endothelial growth factors (VEGFs) in myocardium have not been documented. Methods and Results—Adenoviruses (Ad) at 2 doses (2×1011 and 2×1012 viral particles) or naked plasmids (1 mg) encoding Lac Z control, VEGF-A165, or the mature, soluble form of VEGF-D (VEGF-D&Dgr;N&Dgr;C) were injected intramyocardially with the NOGA catheter system into domestic pigs. AdVEGF-D&Dgr;N&Dgr;C gene transfer (GT) induced a dose-dependent myocardial protein production, as measured by ELISA, resulting in an efficient angiogenic effect 6 days after the injections. Also, AdVEGF-A165 produced high gene transfer efficacy, as demonstrated with immunohistochemistry, leading to prominent angiogenesis effects. Despite the catheter-mediated approach, angiogenesis induced by both AdVEGFs was transmural, with maximal effects in the epicardium. Histologically, strongly enlarged &agr;-smooth muscle actin–positive microvessels involving abundant cell proliferation were found in the transduced regions, whereas microvessel density did not change. Myocardial contrast echocardiography and microspheres showed marked increases in perfusion in the transduced areas. VEGF-D&Dgr;N&Dgr;C but not matrix-bound VEGF-A165 was detected in plasma after adenoviral GT. A modified Miles assay demonstrated myocardial edema resulting in pericardial effusion with the higher AdVEGF doses. All effects returned to baseline by 3 weeks. Naked plasmid–mediated GT did not induce detectable protein production or vascular effects. Conclusions—Like AdVEGF-A165, AdVEGF-D&Dgr;N&Dgr;C GT using the NOGA system produces efficient transmural angiogenesis and increases myocardial perfusion. AdVEGF-D&Dgr;N&Dgr;C could be useful for the induction of therapeutic vascular growth in the heart.


The invention provides a conveying and transferring device for talcum powder and relates to the technical field of production and processing of wood-plastic composites. The conveying and transferring device is arranged between a thick conveying pipeline and a thin conveying pipeline. A body is a storage box with the trapezoidal cross section. The storage box is big-end-up. The thick conveying pipeline is connected to the upper end of one side of the storage box. The thin conveying pipeline is connected to the lower end of the other side of the storage box. An auger extending into the storage box is arranged in the thin conveying pipeline. The conveying and transferring device for talcum powder has the advantages of being novel in design and simple in structure; due to the fact that the trapezoidal storage box is arranged between the thick conveying pipeline and the thin conveying pipeline, blockage by the talcum powder is avoided; the conveying and transferring device is convenient to use, effective, high in practicability, high in market value, and convenient to popularize and apply.


Objectives This study was designed to evaluate the healing effect of Cordyceps Militaris (CM) on collagen II-induced arthritis rats. Methods Sprague-Dawley rats were randomly divided into 6 groups (normal, control, positive control, CM with low/medium/high dosage each). Type II collagen mixed with complete Freund's adjuvant (with 1:1 v/v) was injected subcutaneously, and the mixture was injected in a same manner one week after the first injection to boost arthritis. Arthritis index, paw thickness and von Frey test were conducted to observe physical changes. hematoxylin and eosin (H&E) staining was performed to observe knee cartilage. The levels of messenger RNA (mRNA) expressions of interleukin (IL)-1β, IL-6, tumor necrosis factor-alpha (TNF-α) in spleen were assessed by real-time polymerase chain reaction.


Simulations of a shock emanating from a compression corner and interacting with a fully developed turbulent boundary layer are evaluated herein. Mission-relevant conditions at Mach 7 and Mach 14 are defined for a precompression ramp of a scramjet-powered vehicle. Two compression angles are defined: the smallest to avoid separation losses and the largest to force higher temperature flow physics. The Baldwin–Lomax and the Cebeci– Smith algebraic models, the one-equation Spalart–Allmaras model with the Catrix–Aupoix compressibility modification, and two-equation models, including the Menter shear stress transport model and the Wilcox k-! 98 and k-! 06 turbulence models, are evaluated. Comparisons are made to existing experimental data and Van Driest theory to provide preliminary assessment of model-form uncertainty. A set of coarse-grained uncertainty metrics are defined to capture essential differences among turbulence models. There is no clearly superior model as judged by these metrics. A preliminary metric for the numerical component of uncertainty in shock– turbulent-boundary-layer interactions at compression corners sufficiently steep to cause separation is defined as 55%. This value is a median of differences with experimental data averaged for peak pressure and heating and for extent of separation captured in new grid-converged solutions presented here.

The observation that people already carry lots of personal devices (e.g., a smart phone, an electronic identity card, an access badge, an electronic car key, a laptop, . . . ), serves as starting point for this thesis. Furthermore, with the arrival of smart objects, the number of things that think one carries is expected to grow. Sensors will be built into clothing and attached to the body to monitor our health. It is clear that these devices need to be protected. However, due to the vast amount of devices involved, the traditional approach of protecting each device on its own, results in a usability nightmare. We investigate how to tap into the potential that arises from cooperation between these devices. This is done by deploying threshold cryptography on personal devices. Threshold cryptography has the benefit of increased overall security, since an adversary can compromise a number (up to the threshold number) of devices without gaining any advantage towards breaking the overall security. Furthermore, the end-user does not need to carry all his personal devices, any subset of size at least the threshold number is sufficient to make use of the threshold security system. We propose technical solutions to tackle some of the practical issues related to this approach, paving the road for real world implementations. First, we show how one can include devices that do not have the necessary (secure) storage capabilities needed to store shares (e.g., car keys) in our threshold scheme. Second, we investigate how the end-user can add or remove devices from his set of personal devices used in this threshold scheme. Finally, in order to get user acceptance, the (location) privacy of consumers should not be disregarded. Towards this goal we examine how to achieve private and secure device authentication over an open channel. This is done specifically for RFID tags, which are the least powerful devices that can be included in our threshold system. Hence, the location of the end-user can be kept private, while all communication between his personal devices, that arises from our threshold solution, goes over an open channel.


Indonesi next 21 th century will face three big problems i.e. science and technology development, ecology and emography. These problems will caouse Indonesian toward complicated position unless they increase and improve the quality of education. University is one of the  formal high education which must develop the human resources in order to be able to solve the problems. Indonesian always hopes that university can produce sklilful scholars who are able to advance the nation welfare.


The propagation of a cylindrically polarized vectorial (CPV) beam through uniaxial crystals orthogonal to the optical axis is studied. Analytical formulae are derived for the field components of the beam upon the propagation. Intensity distributions and degrees of polarization of the beam after the propagation are revealed by numerical simulations, respectively. It is demonstrated that the beam profile no longer remains cylindrically symmetric all along the propagation due to the effect of anisotropy of the crystal. Furthermore, it is also shown that both the beam properties and anisotropy of the crystal can affect the evolution of CPV beam. These conclusions may provide specific knowledge of the propagation properties of CPV beam by the use of the crystal as a fundamental optical element.


NK-dependent clearance of RMAS lymphoma and B16 melanoma (MHC I low ) has been demonstrated in NK cell-deficient mice (Kim S et al, PNAS. 2000 Mar; 97(6): 2731–6) . We recently investigated the roles of granzyme (Gzm) A and B in NK-dependent clearance of RMAS and B16 cells. The survival curves following intravenous injection of 2x10 5 RMAS cells are shown in the Figure; similar results were found with B16 cells. All granzyme AxB-deficient mice died within 6 weeks. Survival of granzyme A-deficient mice was similar to that of WT mice. Surprisingly, granzyme B-deficient mice were more resistant than WT mice to these tumor challenges. Previously, our laboratory demonstrated that human regulatory T (Treg) cells can use the granule exocytosis pathway to kill a variety of autologous immune cells in vitro (Grossman WJ et al, Immunity. 2004 Oct; 21(4): 589–601) . Based on these results, we hypothesized that these tumor cell lines may induce granzyme B expression in Tregs, which in turn suppress the function of the NK cells responsible for clearing the tumors. Indeed, flow cytometric studies revealed that granzyme B (but not granzyme A) was highly expressed in 10–30% of CD4 + /FoxP3 + Tregs found in the tumor environment (i.e. ascites fluid, tumor-infiltrated livers, or lungs). In contrast, very few granzyme B-expressing cells ( in vivo , we purified Tregs (95% pure CD4 + /CD25 + cells) from the resting spleens of both WT and granzyme B-deficient mice, and co-injected them intraperitoneally with 2x10 6 luciferase-tagged RMAS cells into granzyme B-deficient mice. Tumor burden was assessed using in vivo bioluminescence imaging. Add-back of 2x10 6 WT Tregs into granzyme B-deficient mice restored tumor growth to 40% of that observed at day 7 in WT mice, whose tumor burden was approximately 50-fold higher than that of granzyme B-deficient mice. Add-back of equal doses of granzyme B-deficient Tregs had no effect on tumor burden. Our data suggest that these tumor cell lines induce the expression of granzyme B in Tregs, which subsequently suppress tumor-specific NK cells. These data demonstrate for the first time that granzyme B plays a crucial role in Treg-mediated suppression of NK cell function in vivo . By recruiting and activating Tregs that inhibit NK cell function, these tumors gain a survival advantage that is lost in the setting of granzyme B deficiency in the Tregs. This study therefore suggests that targeted inhibition of granzyme B in Tregs may represent a novel approach to break Treg-mediated tumor tolerance.


This paper uses …eld experiments to identify substantial and persistent arbitrage opportunities on online auctions sites. Auction and two-sided market theory require price disparity to be small for competing sites of di¤erent sizes to coexist in equilibrium. Yet, statistical evidence suggests a violation of this no arbitrage condition in eBay and Yahoo coin markets. Buyers on eBay pay 20 to 60 percent more than those on Yahoo, despite buyer and seller mobility between sites. The magnitude of the revenue di¤erence is striking, overwhelming possible rationales relating to information availability, the value of reputation and trustworthiness of site users. The price disparity may signal unexploited opportunities or represent a market in transition.


Moyamoya disease (MMD) is characterized by a progressive steno-occlusive disease affecting the terminal portions of the cerebral internal carotid artery (ICA) and by formation of an abnormal vascular network at the base of the brain. Several pathogeneses, including inflammation, immune complex, upregulation of angiogenic factors, and abnormality of endothelial progenitor cells (EPCs) have been hypothesized. However, the mechanisms of MMD are largely unknown, and in vivo and in vitro models of MMD have not yet been established. Previously, inflammation- and immune-complex-related animal models have been reported but failed to reproduce severe stenotic lesions in the terminal portion of ICA. Thereafter, several clinical studies revealed that angiogenic activity of circulating EPCs was defective in MMD patients. These results suggested that the function and quantity of EPCs could be useful as a cellular model of MMD. Very recently, RING finger protein 213 (RNF213) was identified as an MMD susceptibility gene, a discovery that led to the efforts to generate gene mutation-based animal models. Although RNF213 knockout animal models have not yet successfully represented the phenotype of MMD, they have provided new insights into the role of RNF213 in remodeling after vascular injury and postischemic angiogenesis. Furthermore, the use of induced pluripotent stem cells (iPSCs) and an appropriate differentiation protocol have made it possible to obtain abundant quantities of MMD-specific vascular cells. In summary, studies have shown that endothelial cells derived from MMD-iPSCs have impaired angiogenic activity, which is a finding consistent with the results of EPC studies. Further studies are needed to create true MMD-specific experimental models to promote understanding of MMC pathogenesis and aid drug development.

Conclusion: cDNA microarrays technology may be power tools in discovering the possible mechanism of drug in gene level,and provides new informations for further research.


Abstract : The purpose of this report is to provide profiles of Active Duty Army nurses to aid in developing strategies and policies for recruiting, managing, and retaining registered nurses in the face of a national nursing shortage. Data from Defense Manpower Data Center personnel files were used to described Regular Army (RA) nurse officers as of September 30, 1987 and transactions information was used to identify those who entered and those who left Active service in FY 1987. Profiled characteristics include: age, gender, race-ethnic group, martial status, number of dependents, highest educational level, rank, age at service entry, length of service, and nursing specialty. Comparisons of RA nurses and USAR nurses are made on the basis of Volume I of this series of reports.


It is generally accepted that the nonlinear I–V characteristics for semiconductor nanostructures are mainly induced by the Schottky contacts or by the space charge limited transport mechanism. We perform I–V measurements on undoped and doped In–Zn–O compound nanobelts and confirm that their intrinsic non-ohmic transport behaviors are not caused by these mechanisms. A model based on the hopping assisted trap state electrons transport process is introduced to explain the nonlinear I–V characteristics and to extract their electrical parameters. An understanding of this trap-state influenced carrier transport can advance the progress of nanomaterials applications and enable us to distinguish their intrinsic transport behaviors from contact effects. The results also indicate that the material has good electrical properties and can be used as a potential substitute for In2O3.


Objective: To estimate the prevalence of malignant and premalignant lesions among endometrial polyps and correlate this prevalence with risk factors for endometrial neoplasms. Methods: Review of clinical and histopathological data on polyps resected during hysteroscopic polypectomies performed from January 2005 through July 2013 at Hospital de Clínicas de Porto Alegre (HCPA), Brazil. Results: The sample comprised 359 patients who underwent hysteroscopic polypectomy. Overall, 87.2% of patients had benign polyps and 9.9% had hyperplasia without atypia. Polyps with atypical hyperplasia were found in 2.6% of patients, and endometrial adenocarcinoma, in 0.3%. Polyp malignancy/premalignancy correlated with patient age, menopausal status, and presence of abnormal uterine bleeding. All women with malignant/premalignant lesions had abnormal uterine bleeding.The rate of polyp malignancy was higher among tamoxifen users, although the difference did not reach statistical significance (p=0.059). There was no correlation with hypertension, diabetes mellitus, obesity, hormone replacement therapy, endometrial thickness, or polyp


Electroless Ni-Zn-P alloy deposits from an alkaline bath containing NH 4Cl as a buffer agent and sodium citrate as a complexing agent was investigated.The effects of deposition parameters(pH,concentration of ZnSO 4 ·7H 2O and temperature) on the plating rate and the deposit composition was examined respectively.It was found that the presence of zinc in the bath has an inhibitory effect on the alloy deposition.As a consequence,the percentage of zinc in the electroless Ni-Zn-P alloys never reaches high values.The structure and the crystallization behavior of the deposit has been characterized by XRD and DSC.The results show that the as-plated deposits consist of mainly an amorphous structure together with some cubic phase Ni.The deposits crystallized into Ni 3P at 384.8℃ and transformed into Ni 5Zn 21 at 580.7℃.The weight loss test and the anodic polarization measurements of the as-plated and the heat-treated deposits in 3.5mass% NaCl solution (pH7.0) indicate that the two deposits show good corrosion resistance,especially the as-plated deposit.


Transparent AlN ceramics were prepared by spark plasma sintering(SPS) technique with 3%(mass fractin) CaF_2 as sintering additive.Samples achieved 99.5% relative density and 52.4% maximum transmittance after 15min holding time by spark plasma sintering at 1800℃ and 30MPa.The results from XRD,SEM,TEM and EDX show that the sintered bodies are densely compacted and highly pure with fine grain size and uniform microstructures,and no secondary phases are observed at the grain boundaries or triple grain junctions.The presence of CaF_2 induces liquid phase sintering,which promotes the growth of AlN grains and the densification of the sintered bodies.The resultants of fluorides and Ca-Al-O compounds from reaction between CaF_2 and AlN can evaporate from sintered bodies and further purify the sintered bodies,which indicates that CaF_2 is an effective sintering additive.SPS is an effective method for the fabrication of transparent AlN ceramics.


Ability is the center of self-worth. In an achievement situation, when individuals face a possible failure, they may use self-handicapping strategies for purposes of self-worth protection and self-presentation. From the point of emotion regulation, self-handicapping is an adaptation strategy. However, it is not an adaptation strategy for achievement performance. It will lead to low achievement and more requirement of self-handicapping.

The ability to estimate the shear strength of rock joints provides for a rapid assessment of the stability of existing and future rock slopes. Expensive and time consuming direct shear tests can be avoided if two simple index tests are performed. First a direct shear test is carried out on a block containing a typical joint through the whole rock. The block is tilted until the joint is so steeply inclined that the upper half slides down the joint plane. This angle of inclination taken together with the dimensions of the block, gives a measure of the surface roughness, smooth joints may slide at angles of only 30 degrees, while rough joints may not slide before 70 or 80 degree inclination. The second index test is designed to measure the compressive strength of the joint walls, which will often be lower than that of the fresh rock if the joints are weathered. The strength is measured with a Schmidt hammer, which is a simple device for recording the rebound of a spring loaded plunger after its impact with the joint surface. /TRRL/

Since the near infrared spectrum (wavelength range of 750–1100 nm) is the region of highest physiological transmisivity, it is the optical communication gateway for the laser energy to propagate into the human body. This optical window also leads to nanoparticle-based approach where embedded nanoparticles absorb the laser light designed to address the specific diagnostic and therapeutic challenges of cancer therapy is exploited extensively in so called plasmonic photo thermal therapy (PPTT). A new tool that is under development for cancer/tumor treatment, in which embedded nanoparticles are manipulated to absorb the Near Infrared (NIR) laser light intensely, aiming at addressing the "nonselectivity" problem that exists in the conventional photo thermal therapy (PPT). The purpose is to seek therapy with a faster and accurate procedure with a comprehensive treatment plan aided with fast and accurate numerical simulations as well. Among all the nanostructures, the noble metal nanoparticles (such as nanoshells) could be tuned to have peak absorption cross section in the NIR spectrum which provide very intense local heating to burn the deeply embedded cancerous tissues and tumors rather than the healthy tissue. Experimental and numerical studies have shown that designed gold nanoshells can be used to remotely and optically induce hyperthermia by embedding certain amount of absorbing dominated gold nanoshells in tumors and then irradiated using NIR laser light. Advancing our capabilities such as modeling, characterization and design of complex nanostructures and their host media for various nanophotonic applications will also increase our effectiveness of induced hyperthermia for its future applications. The computational tools should bridge across the scales from nano to macro, and rapidly compare the predicted behavior of a large number of nanoparticles embedded in tissue so that experimental groups could concentrate laboratory efforts on those resulted configurations most likely to provide optimum results.Copyright © 2009 by ASME


Synthesis and Properties of S-(Trifluoromethyl)polysulfanemonosulfonates CF3SxSO2M [x=1, M = OH, NH4O, 1/2 HgO2, (CH3)2N, NH2; x=2, M = NH4O]*

Hydrolysis of CF3SNSO with 2 equiv. of H2O provides [NH4][CF3SSO3] (1), which on treatment with chlorine gives CF3SCl and [NH4][ClSO3]. Trifluoromethyl thiosulfates are synthesized from Hg(SCF3)2 and ClSO2M [M = NH4O, (CH3)3SiO (2), (CH3)2N (3), NH2 (4)]. Insertion of SO3 into Hg(SCF3)2 provides Hg[CF3SSO2O]2 (6). Similarly, S-(trifluoromethyl)thiosulfuric acid (5) is obtained from CF3SH and SO3. New preparations for CF3SXNSO (x=1, 2) are described. These compounds are formed either from Hg(NSO)2 or (CH3)3SiNSO and CF3SxCl in good yields. CF3SSNSO (8) reacts with water to give [NH4][CF3SSSO3] (9). A 1:1 adduct (10) is obtained from CF3SNSO and AsF5. A preliminary X-ray structure investigation proved that AsF5 is coordinated to the oxygen atom. Some reactions of [NH4][CF3SSO3] and CF3SSO2OSi(CH3)3 are mentioned.


In the current paper, some aspects regarding the quality of the surface machined under different lubrication conditions is being assessed: cutting under a jet of cutting fluid, minimum quantity lubrication cutting, dry cutting. The objective was to assess the results obtained after MQL cutting in comparison with dry cutting and cutting under a jet of cutting fluid. The variables of the cutting regime were the feed rate and the type of milling (climb and conventional). This study has an important ecological impact over the use of cutting fluids.


The present studyhad as general objective to analise the solution of problems with an addition structure from the pupils of the third year of the fundamental teaching,
aiming to identify which kind of problems present difficulties to the pupils. The subjects of this research were pupils who belonged, on the whole, to two private school and one state
school of Campo Grande/ MS. It was checked that the degree of the difficulty was bigger when the problems: 1) presented desconnection between the operation to be solved and the verbs or expressions in which the informations were; 2) didn't search state (begginer,
intermediate or final), but the relationship or transformations; 3) demanded inversion of the
time sequence. It is believed that the teacher has a fundamental role in overcoming these kind of difficulties, when the one understands that the problems aim the building of concepts and that their solving must be proved by various situations.


Two general sorts of responses to the suffering caused by the 9/11 attacks are distinguishable in the statements of public officials, journalists, and citizens: one manifests a tragic sensibility, another takes the form of theodicy. Each response entails a distinctive set of expectations about the nature of political agency and solidarity in a democracy. With its claim of access to a transcendental form of truth, theodicy promises a robust sense of political solidarity and agency based on a shared religious belief. Tragic modes of appeal muster their consolatory effects by appealing to intuitions or taste rather than religious belief and therefore potentially remain open to more diverse public audiences.


In the presence of chiral organic catalysts, the optically active 4H‐chromine was synthesized from the multicomponent condensation of 5,5‐dimethylcyclohexane‐1,3‐dione with malononitrile and methylene‐active compound, and the specific angle of rotation of the compounds was determined in the AUTOPOL‐III polarimeter and their structures were confirmed by the X‐ray spectroscopic analysis method. These optically active 2‐amino‐4‐aryl‐7,7‐dimethyl‐5‐oxo‐5,6,7,8‐tetrahydro‐4H‐chromen‐3‐carbonitriles were effective inhibitors of α‐glycosidase, the cytosolic carbonic anhydrase I and II isoforms (hCA I and II), and acetylcholinesterase (AChE) enzymes with Ki values in the range of 21.33 ± 1.11 to 40.24 ± 10.78 μM for hCA I, 28.91 ± 6.51 to 59.97 ± 15.62 μM for hCA II, 18.16 ± 3.18 to 66.57 ± 1.36 μM for α‐glycosidase, and 8.68 ± 0.93 to 102.61 ± 24.96 μM for AChE.

This paper argues that the normative character of our unreflective situated behaviour is not factual. We highlight a problematic assumption shared by the two most influential trends in contemporary philosophy of cognitive science, reductionism and enactivism. Our intentional, normative explanations are referential, descriptive or factual. Underneath this assumption lies the idea that only facts can make true or false our attributions of cognitive, mental and agential abilities. We will argue against this view by describing the main features and problems of reductionism and enactivism and then we will offer two arguments against this shared factualist assumption: (1) normative vocabulary is ineliminable if we want a complete explanation of our situated practices; and (2) the factualist assumption is a species of the is-ought fallacy. Finally, we will claim that a folk psychological explanation of our normative practices is fully compatible with ontological naturalism when such descriptivist or factualist assumption is rejected.


ABSTRACT This paper addresses the consensus problems for two kinds of hybrid multi-agent systems. The first kind of hybrid multi-agent system is composed of first-order discrete-time and second-order continuous-time dynamical agents. Based on different interactive modes, two effective protocols are presented for the hybrid multi-agent system, respectively. By using graph theory and system transformation method, some criteria are obtained for solving the consensus problem. The second one consists of first-order continuous-time and second-order discrete-time dynamical agents. The effective protocols are also proposed to guarantee the consensus. Meanwhile, the necessary and sufficient conditions are established for solving the consensus problem. Simulation examples are provided to demonstrate the effectiveness of theoretical results.


Eukaryotes employ an evolutionarily conserved catabolic process of protein degradation called autophagy. It is a dynamic process in which large protein aggregates, entire organelles, and bulk of cytoplasm is sequestered within double membrane vacuoles and delivered for degradation to lysosomes. Quercetin is a naturally occurred flavonoid. Although the antioxidant properties of quercetin have been demonstrated in numerous studies, its effect on autophagy regulation is not known. The purpose of this study was to investigate the effect of quercetin on autophagy regulation in cell culture model (human rhabdomyosarcoma cell line). We found that quercetin (50 μM and 100 μM) inhibited autophagy demonstrated by Western blot analysis of the LC3 lipidation. Autophagy is a highly controlled process and Akt has been shown to negatively regulate autophagy. In our studies, quercetin‐induced down‐regulation of autophagy was associated with an increase in Akt activation demonstrated by increased level of Akt phosphorylation. We conclude that quercetin appears to be a potent autophagy modulator. Further studies are needed to fully determine cellular and molecular mechanisms of quercetin on autophagy regulation.

Objective:To observe whether there was asymptomatic neurosyphilis in treated latent syphilis with persisting positive RPR(more than two year ) who have no neurologic symptoms.Methods:Routine test and treponemal antibodies were measured in cerebrospinal fluid(CSF) of these 25 patients.Results:26(64%) had mildly elevated protein concentration and 9(36%)glucose concentration in CSF. Treponemal antibodies test: 7 (28%) had treponemal antibodies in CSF : 1(4%)VDRL,2(8%)FTA-Abs,7(28%)TPHA were positive; there were significantly differences among these treponemal antibodies in CSF(P0.05).Conclusions:The results indicated there could be an asymptomatic neurosyphilis in these patients partly and could be one of the reasons with persisting positive RPR and very diffcult to antisyphilitic threapy. If VDRL postive in CSF was considered as the only diagnostic criteria of asymptomatic neurosyphilis, most of these patients would be missed.


We report electron transport measurements on a single-island single-electron transistor capacitively coupled to an isolated double quantum dot at 4.2 K. The structure is fabricated through trench isolation in silicon-on-insulator. We detect single-electron polarization of the isolated double quantum dot using the single-electron transistor as a sensitive electrometer, and estimate its charging energy. We observe a large suppression of current and modulation of Coulomb blockade peak heights as a function of applied gate voltages.

The current food system is dependent upon the prevailing industrial (rural) farming system that rests upon unlimited access to fossil fuel/energy, fresh water, land, plus relatively stable climates. In the twenty-first century, all of these resources are in steep decline and yet the demand for food is growing exponentially due to rising standards of living and growing urban populations. With the increasing affluence of consumers globally, along with the increase in population, the need for increases in food production continues to intensify. The possibilities for creating an ecologically sustainable, new urban food production system are limited only by our imaginations. If the focus is the growing of fresh food, locally/regionally, year round, the opportunities are huge. This paper explores the principles of sustainable food systems, and how these principles can be used to create a new, ecologically friendly, urban/periurban, knowledgebased, twenty-first century food production system.


Abstract This paper is concerned with the limit analysis of curved I-beams made of a rigid perfectly plastic material. After the introduction in Section I, Section II deals with the definition of the problem and the derivation of the yield curve in the space of the bending moment M and axial force N. An experimental verification of the theory is given in Section III, and systematic application to rolled I-beams is described and discussed in Section IV. Section V shows examples of arch problems


The TDD mode is considered as a key solution to support the asymmetric traffic for multimedia services. With the TDD mode however, the intercell interference becomes serious in the cross time slot (CTS) period and this interference seriously degrades the system performance. In this paper, we propose a minislot borrowing scheme on top of the region and time partitioning dynamic TDD (RTP D-TDD) for OFDM systems. To mitigate the inter-BS/inter-MS interference in the CTS period, each time slot in the CTS period is split into minislots, and a cell is divided into several regions by the number of minislots in a time slot in the CTS period. In the MBS systems users in the overloaded region borrow minislots which are estimated with the lowest CCI in addition to the corresponding minislots. By the computer simulation, it has been verified that the proposed MBS with TRTP outperforms conventional time slot allocation schemes in both the outage probability and the bandwidth efficiency.
