Aluminum profiles are widely used as the materials for high speed train body, thus the service safe reliability of the welded joints on structure is important for the whole system. Residual stress has a great influence on the fatigue life of joint, so a accurate,non-destructive and quick test of the residual stress on aluminum profiles for high-speed train is a significant work. The residual stress of the MIG welded joints on 3 mm thickness 5083-H111 aluminum profiles are investigated by blind hole-drilling method and X-ray diffraction(XRD)method in this paper. It shows that the values of residual stress tested by blind hole-drilling method are lager than those tested by X-ray diffraction(XRD)method,and the latter has larger variation range of the values,this is mainly caused by the different test depths. However, the overall trend of results of two methods is consistent, which means it's feasible to test residual stress of the MIG welded joints on 3 mm thickness 5083-H111 aluminum profiles by X-ray diffraction(XRD)method.

Abstract The mechanical behaviour of wood over time depends on temperature, relative humidity, applied load and the direction of the applied load, among other factors. In the present study, the mechanical behaviour of sugar maple (Acer saccharum Marsh.) wood was determined using creep tests in cantilever bending. These tests were carried out at different load levels, in a controlled environment chamber at a constant temperature of 30± 0·5°C and a relative humidity of 37, 67 and 83% for constant conditions and a relative humidity ranging from 37 to 83% for variable conditions. The specimens were oriented in a radial pattern and cut to 110 mm in length, 25 mm in width and 7 mm in thickness. The results show the impact of load levels and moisture content. Under constant conditions, the results show a linear behaviour of viscoelastic creep. Under variable relative humidity conditions, changing moisture contents resulted in significantly higher creep (mechanosorptive) compared to constant conditions.


The simple genetic algorithm is applied to find the pollution source location in groundwater. Numerical test is used to find the influence of estimated pollution range on the time consuming, mean, and standard deviation of identification result. The bigger the estimated range is, the more time is consumed. A slight movement of the estimated source in the direction perpendicular to the major migrate direction leads to big bias between the calculated source location and the real location. The chance that optimization model falls into the local optimum location is growing in the major migration direction.


Introduction: In most society pregnancy period is seen as a very vulnerable period for both the mother and the child. All cultures recognize pregnancy as a special transition period and many have particular cultural beliefs and customs that dictate activity and behavior during pregnancy. During pregnancy period our society practicing certain beliefs. Among the all kinds of beliefs some have beneficial effect, some have harmful effect & some belief have no effect on health.


Tumor cells rely on the Integrated Stress Response (ISR) to adapt to different environmental and physiological stresses. The ISR is comprised of four eIF2 kinases that sense different stresses and catalyze phosphorylation of the alpha subunit of eIF2. This results in inhibition of global translation initiation, but at the same time results in preferential translation of select mRNA transcripts in order to relieve stress. Recent work has suggested that programmed death-ligand 1 (PD-L1), a cell surface protein commonly upregulated by tumors to evade the immune system, may be translationally regulated by the ISR in cancer. PD-L1 interaction with immune-checkpoint receptor programmed death-1 (PD-1) leads to the negative regulation of T cell activation and inhibitors that block the PD-L1/PD-1 interaction are widely used to treat different cancers. The ISR may serve as a novel therapeutic target to modulate PD-L1 protein levels and treat immune-evasive cancers. Our group has previously reported that dietary protein restriction increases the anti-tumor effect of PD-1 inhibition in the RENCA kidney cancer mouse model. Here, we show that in the RENCA model, phospho-PERK and phospho-eIF2α protein levels correlate with PD-L1 induction associated with dietary protein restriction. This is supported by TCGA data that shows a correlation between PERK and PD-L1 mRNA levels in different genitourinary cancers. In vitro, activation of the eIF2 kinases PERK and GCN2 by ER stress and amino acid starvation, respectively, in both RENCA cells and prostate cancer cells, leads to induction of PD-L1 protein without changing mRNA levels, suggesting preferential translation under stress conditions. Inhibiting PERK using selective inhibitors blocked ER stress-induced induction of PD-L1. These data support the notion that PD-L1 is induced by dietary protein restriction and is translationally regulated by the ISR. Modulating PD-L1 protein levels in immune-evasive tumors by targeting the ISR in the context of dietary protein restriction may enhance the anti-tumor response to immune checkpoint inhibitors.

Atmospheric motion over obstacles on plane surfaces to compute simulated wind fields over terrain features was studied. Semielliptical, two dimensional geometry and numerical simulation of flow over rectangular geometries is also discussed. The partial differential equations for the vorticity, stream function, turbulence kinetic energy, and turbulence length scale were solved by a finite difference technique. The mechanism of flow separation induced by a semiellipse is the same as flow over a gradually sloping surface for which the flow separation is caused by the interaction between the viscous force, the pressure force, and the turbulence level. For flow over bluff bodies, a downstream recirculation bubble is created which increases the aspect ratio and/or the turbulence level results in flow reattachment close behind the obstacle.

In this paper, a dynamic I2SR model based on rumor spreading with random noise interference is proposed. Active state of the spreaders and the random noise interference in the homogeneous network can be considered. This paper divided spreaders into high probability spreaders and low probability spreaders that can be transformed. The existence and uniqueness of global positive solutions, extinction , and the spreading range of rumors be proved. Through numerical simulation, we have three conclusions as follows: (1)The spreaders can quickly reach to the peak in the shorter time with the bigger of the transmissions rate;(2)The high probability spreaders not only pay more attention to rumors but also more likely to spread;(3)There have a negative correlation between the spreading range of rumors and noise intensity.


This forty-page monograph describes the results of tests carried out by pilots in the Cambridge cockpit testing machine, in which 355 pilots carried out a test lasting forty minutes. The Cambridge cockpit is a replica of the normal aeroplane, and the apparatus is designed to copy flying conditions with suitable changes in the readings of the instrument panel, and alterations in position of the cockpit, noise, etc., which accurately mimicked flying conditions. The'test was divided into four ten-minute periods, and the movements of the levers by the pilot following the changes in the instrument readings were all plotted. The test was standardized, and about 75 per cent. were regarded as normal. Those who were abnormal (87 subjects) were marked by two distinct reactions. Two-thirds were classified as showing the overactive reaction. Their movements to stabilize the plane, correct direction and height, etc., were rapid and excessive. They became irritable, and angry either with the machine or themselves; they swore, and thumped on the controls, but seldom damaged the machine. They tended to concentrate upon one part of the problem, and neglected others. Those who showed this reaction returned later and wanted to do the test again,-and they clearly showed an abnormal reaction to the procedure. The test had produced a postexperimental, too persistent, wrought-up feeling. One third of the abnormal group showed an inert *reaction. In the last period of the test these subjects' errors were large and the activity to correct the machine was small. There was a general omission of the .necessary readjustments, but deterioration was selective and did not affect all -parts of the test at once; the instruments furthest away from the centre of vision were most neglected. They became indifferent-, they lacked the appreciation of the changed readings which they should have shown, and they markedly underrated their own faults. Both groups showed much worse reactions when they knew-they were reaching the end, than when they did not. The abnormal subjects often showed preoccupation with one part of the task and were unable to organize their attention in such a way that they could attend to all the details at once. This apparent failure in behaviour was not associated with failure in the ordinary tests of intelligence, and surprisingly the author can find littlejustification for the belief that fatigue alone is the cause of failure. There was good reason to believe that when it could be pointed out to the subjects what difficulties were likely to be-encountered, and how these can be checked, the performance was improved. Results were impaired seriously by alcohol. Benzedrine in small doses gave conflicting results, but it did improve capacity after a sleepless night The effects with barbiturates, caffeine, and vitarhins were observed in some subjects. With the first two no conclusions were reached. With, the latter, no alteration was produced despite large doses. It was not found possible to explain the results on the theory of fatigue, since no simple relation existed between frequency of errors and the duration of the test. If fatigue cannot be incriminated, what explanation of the results can be given ? The author indicts " anticipatory tension," a process in'all normal persons which lessens as success is gained. In the abnormal subjects the wish to succeed and the fear that they may not, result in the errors found. Confirmation of this was found in the study of the responses of thirty-nine patients, where the findings in the cockpit experiences were compared with the results of interviews with two independent psychiatrists, and where there was close correspondence between test results and subsequent flying career. The application of these results to industry may seem small. Yet every factory has its overactive and inert persons, some of whom are problems when they are not actually accident-prone. It is seldom that matters of life and' death weigh so heavily as in the conditions copied in the Cambridge cockpit. Yet such a study can hardly afford to be neglected, for several reasons. It confirms the doubts as to how far fatigue alone plays a part in accidents. It emphasizes human variables. It throws doubt on the efficiency of aptitude tests alone, divorced from the problem of the persistence of skill. We may find by the new tests the apt workman. Can we ensure so far as the delicate processes go that his skill will continue, or will he constantly be giving variable results because his performance can so seldom be relied upon? Dr. Davis's paper should be studied alongside Grinker and Spielgel's Men Under Stress, a study of breakdown in U.S. airmen. The memorandum under review is very silent upon psychiatric problems and theory. But it does quietly emphasize how important these theories are, and it throws into commendable perspective the relationship between theory and the practical results which are presented. This contribution from an academic psychological laboratory is an admirable survey. Is it too much to hope that bequests and grants should be given to quiet investigations of this sort, even though large-scale or immediate benefits are unlikely to follow ? Henry Wilson.


A CMOS 80–400 MHz 5TH order Chebyshev Gm-C low-pass filter with a unique auto tuning system is presented. The filter was designed and fabricated with TSMC 0.13-μm RF CMOS process. Experimental results show that the cut-off frequency of the filter can be tuned between 80–400 MHz, with a tuning step less than 7MHz and an average tuning error of 3.6%. The filter also realizes gain of 0–30 dB, IIP3 of 16.5 dBm and NF of 14–18 dB. Dynamic range of the filter for THD less than 1% is 74 dB. Power dissipation is only 9 mW with 1.2 V supply voltage.


This paper proposes a patch-based method to address two of the core problems in image processing: denoising

and inpainting. The approach is based on a Gaussian mixture model estimated exclusively from the observed

image via the expectation-maximization algorithm, based on which the minimum mean squared error estimate

is computed in closed form. The results show that this simple method is able to perform on the same level as

other state-of-the-art algorithms.


I explore how many within modern industrial societies currently understand, manage, and respond to their emotional suffering. I argue that this understanding and management of suffering has radically altered in the last 30 years, creating a new model of suffering, "the negative model" (suffering is purposeless), which has largely replaced the "positive model" (suffering is purposeful) that prevailed in the 18th and 19th centuries. This shift has been hastened by what I call the "rationalization of suffering"—namely, the process by which suffering is predominantly now understood in biological and psychiatric terms rather than in religious, philosophical, or moral. This process accompanied the great forces of secularization, medicalization unleashed at the enlightenment—forces gaining their modern expression through psychiatry, the behavioral psychotherapies, the happiness industries, as well as through aggressive market, individualistic, medical, and positivistic ideas and movements. This shift has entailed many socio/cultural implications important for anthropologists to explore further.


To eliminate the overfitting phenomenon in genetic programming(GP),a new protected approach based on interpolation for some mathematical functions and a method to estimate the smoothness of a GP tree are proposed.Furthermore,to get more accuracy model without losing generalization,the evenness,the complexity and the training errors of the model should all be considered.However,their effects on the training process are difficult to be decided so a non-dominated sorting based multi-objective GP is proposed to make the evaluation of these effects impersonally.Finally,to test the capability of the new approach,a real modeling problem arising from industrial Avermectin process and numerical examples were used and the results show that the improved GP has more chance to find an acceptable solution with higher generalization and without losing accuracy.

In recent years, both industrial and academic world are focussing their attention towards the development of sustainable composites, reinforced with fibres. In particular, among the fibres that can be used as reinforcement, the uniaxial glass fiber ones represent the most interesting for their properties. The aim of this work is to illustrate the results of friction and wear behaviour of uniaxial glass fibers with silicon carbide, aluminium oxide and graphite as the fillers. Moreover, its main manufacturing technologies have been described. The major component of these hybrid composite is uniaxial glass fibre with Epoxy LY556 (Resin). Hardener HY951 is used for hardening and support. Resin + Hardener are mixed in the ratio 10:1 and the mixture made up is called Matrix. Test materials of glass Fibre with varying compositions of 15% Al2O3 + SiC and glass fibre with varying compositions of 15% Graphite + SiC have been prepared by applying the matrix on glass cloth which is wrapped around the mandrel. The samples were tested in a pin-on-disc machine to determine the friction and wear losses. Further, the samples were tested on a pin-on-disc machine and frictional characteristics were monitored by varying speed and loads. Thus, the friction and wear characteristics have also been found out for the two specimens. From the experimental test results, it is observed that Al2O3 +Sic exihibits lower wear loss than SiC + Graphite under dry sliding conditions. Based on the observations, this hybrid composite are recommended to the manufacturing of the aircraft structures.


Upgrading Polish–Chinese relations to a strategic partnership in 2011 became a symbol of closer cooperation between the two countries. However, the relations at the top level are not sufficient to exploit the full potential of the partnership. The local administration is best positioned to stimulate the development of practical cooperation. Hence, Polish local governments should pursue closer relations with China's western regions, use existing tools (direct railway connections, partnership agreements, regional offices) more effectively, and advocate cooperation based on mutual benefits.


It was analyzed the impacts of tourism activities on the environment of the water-eroded cave with the changes of air, climate and biology. The change of environment of the water-eroded cave to the effect of the landscape of the water-eroded cave was disscussed. Some countermeasures of protection have been put forward for the environment and the landscape of the water-eroded cave by the mechanism of the impacts of tourism activities on the environment and the landscape of the water-eroded cave.

was not a sudden innovation but evolved gradually from Baroque forms, in Italian arias as much as in instrumental music. Ornamentation is a valid and universal means of musical expression and can, indeed, play an indispensable part in sonata form, as in the recapitulation section of a Mozart Adagio. Likewise, the extemporaneous variation used by singers of opera seria could (and can today) turn a tedious and perfunctory repetition into a lively extension and enhancement of ideas. To distinguish this quality from 'virtuosity', meaning pure display, would, again, demand careful musical analysis. But musical analysis, unlike its literary analogue, is something that Wood has specifically excluded from his tool chest. 'In keeping with the new musicology,' he writes, 'this book mostly emphasizes cultural analysis of musical practices and reception rather than works; it examines music cultureçperformers, events, and patronsçmore than formal aspects of the current repertory' (p. 12). Of course, studying the part played by musical activity in human life has always been an essential ingredient of musicology. But to pass over the meaning and character of the music (which is admittedly much more difficult to put into words, or relate to life in general, than that of poetry or fiction) is to reduce it to the status of a mere accessory to other events. Wood recognizes the danger: 'As to the actual pleasures of music . . . current literary criticism is resolutely deaf ' (p. 157). Yet he is not immune to the danger himself. 'The most important disseminating medium for commercial music, the pianoforte fulfilled a range of roles: an emblem of newly leisured status, a magnet for sociability organized around the performance of fashionable songs, and a lightning rod of subjective desires in which the paradox of bourgeois individualismçboth market bound and ''free''ç was daily played out' (p. 153). All perfectly true. But what about piano music's hold over the private feelings, morals, and intellectual curiosity of individual players and listeners, let alone the artistic aims of the composers who catered to them? These are nowhere given the recognition they demand if, as Wood rightly maintains, music held a central position in the English culture of the period. It would not be reasonable to suggest that a literary scholar or cultural historian is bound to equip himself with a knowledge of analytical music theory before assessing the importance of musical culture in literary history, although Wood in a discussion of Liszt's Anne¤ es de pe' lerinage (p. 106) does reveal an unexpected technical understanding of music that he might have put to good use elsewhere. What I am saying is that we cannot fully understand music's role in life without recognizing its own internal forces and their power over human thinking and feeling. Insofar as any 'new musicology' strays from these considerations, it will tend to reduce music to the status of a mere handmaid to economic, social, and political movements.

It is the purpose of this communication to report a method of prediction, for use in epiphyseal arrests, which is based upon cumulative roentgenographic measurements of the femur and of the tibia in growing children. It is proposed, also, to outline the experiences with epiphyseal arrests at The Children's Hospital, Boston, regarding both the accuracy of the predicted effect and the incidence of deformities . . . The chart which is presented for use in prediction must be considered a tentative one, and it will be revised as more data are accumulated. It represents a part of the material from a study of growth which has been in progress since 1940. This study involves approximately 700 children, 87 per cent of whom have residual paralysis in one lower extremity with a normal extremity on the other side; and it also includes observations on 158 normal children . . .

The influence of low-temperature treatment on the reaction of complex formation between olefin groups of polystyrene-polybutadiene block-copolymer and compounds of Rh and Pd is studied. The composition of palladium-containing polymers after the treatment is shown to depend upon the conditions of the reaction. For rhodium-containing polymers based on RhCl 3 , the molar ratio Rh:Cl depends on the duration of cryogenic treatment


In Southeast Europe, warming and drying of summers are stronger than the global trends. In Hungary a significant increase in drought frequency started during the second half of the 20th century. Regional impact studies show that recurrent droughts can cause growth decline and mortality of zonal forests at their lower limit of distribution. This reduction of forested area may lead to a positive feedback in global warming at the forest/steppe limit in the East-Central- and Southeast-European countries. Forests cover can affect regional climate by reducing surface albedo, enhancing roughness lengths and leaf area index, which also have a feedback on the surface water and energy fluxes. For the period 2021-2050 the effect of forest cover changes on the temperature and precipitation extremes has been studied using the regional climate model REMO. For the A1B IPCC scenario, three sensitivity studies have been carried out over Hungary: · Potential forest cover for the simulation period (planned by the Hungarian State Forest Service) · Complete afforestation (except of urban areas and water bodies) · Complete deforestation Sensitivity studies concentrate on the following questions: · Does potential forest cover have any effect on the simulated climate? · Does increased or decreased forest cover induce changes in temperature and precipitation extremes and in the climate variability? How big are these feedbacks compared to the climate change signal? · Can increasing forest cover reduce the drying tendency over Hungary? · Are the effects localised only in the areas, where forest cover has been modified?


Concerns about software-based science reproducibility are ubiquitous throughout the research community as nearly every field of science depends on experiments using computational artifacts. Recently, federally funded research has been mandated releasing data artifacts, but not software and workflow artifacts. Whenever accessible, software artifacts are typically hard to install/use, and experiment workflows are poorly documented and/or ad hoc. This increases the difficulty of replicating results and reusing computational artifacts, slowing down scientific progress. Several software systems have emerged to address this challenge. In this paper, we describe an approach to evaluate these software systems and to determine well they meet needs to replicate and reuse software, data, and workflow artifacts. As an example of the approach, we evaluate our own Occam system.


Transient faults are becoming an increasingly serious concern for logic circuits. They can be caused by thermal neutrons, present at all altitudes, and by other types of ionizing radiation, especially in aerospace applications and nuclear engineering. In this paper we examine issues related to detection of transient errors. The difficulty in testing for transient errors is that they are not always present. Test vectors need to be repeated a number of times in order to detect a fault. We show how to compute a measure for the detectability of transient faults with respect to specific test vectors. This is done using a matrix-based gate-fault model known as the probabilistic transfer matrix model. Using this detectability measure we derive methods to generate multisets of tests to verify probability distributions of faults and detect abnormalities in circuit behavior. Applications of this method include detection of increased atmospheric radiation in terms of its impact on circuits, and testing for process variation that increases the susceptibility of a circuit to transient errors.


points of language: Propertius may use the pluperfect indicative as idly as is suggested on 3. 17, but not all scholars would admit this; largibar in 3. 25 deserves some comment, consuemus in 7. 5 a less mysterious one; and, since the reader is evidently not assumed to be able to read Greek, a morphological note on Adryasin in 20. 12 would be kind. Minor points such as the nature of the dative viro in 15. 8 (if it is a dative) and the grounds for regarding ponto in 15. 29 as dative or ablative could have been dealt with to the advantage of otherwise exemplary notes. Few notes are positively regrettable: it is a pity that those on 1. 1-2 and 2. 2 are so prominently placed. Every reader will look in vain for notes on favourite puzzles (e.g. on 8. 27 hie erit or erat); undergraduates may often be left perplexed (as by 15. 6), or, worse, may assume that all is straightforward. Limitations of space or current Cambridge fashions may explain why so little idea is given of Propertius' real literary peculiarities. Very few readers, in any category, would fail to be grateful for a few remarks on the metre of these elegies in relation to those of earlier and contemporary poets and to Propertius' own fourth book; for some guidance on the nature of the poet's vocabulary (vulgarisms, archaisms, innovations, features proper to elegy and features derived from other forms of verse); for a mention, if not an explanation, of the abstruseness of his mythological allusions, and of the indication of those elements in Propertius which aroused 'the admiration of Ezra Pound', as the dust-jacket points out with seemingly little pertinence to the contents of the book. In fact, Propertius is portrayed in these pages as a pretty stuffy and unpoetical poet. To deal with all these problems would call for an introduction as lengthy and unreadable as Postgate's. Perhaps the poetry will emerge more successfully without too much prompting. This edition does not satisfy the reviewer; probably no edition will satisfy any reviewer, nor any student of Propertius either. Within its limits, Camps's book should be extremely useful, and should succeed in introducing many new readers to a poet who has too long been concealed behind the depressing format of existing texts.

By combining two independent approaches, inelastic neutron scattering measurements and density functional theory calculations, we study the spin-waves in the high-temperature collinear antiferromagnetic phase (AFM2) of Mn$_5$Si$_3$. We obtain its magnetic ground-state properties and electronic structure. This study allowed us to determine the dominant magnetic exchange interactions and magnetocrystalline anisotropy in the AFM2 phase of Mn$_5$Si$_3$. Moreover, the evolution of the spin excitation spectrum is investigated under the influence of an external magnetic field perpendicular to the anisotropy easy-axis. The low energy magnon modes show a different magnetic field dependence which is a direct consequence of their different precessional nature. Finally, possible effects related to the Dzyaloshinskii-Moriya interaction are also considered.


This paper discusses the use of video games for public health communication, as a means of presenting health content in attractive formats, fostering an active stance in seeking such content and enhancing population's social participation. In order to do that, we analyze the concepts of serious games, procedural rhetoric and games as participatory media culture. A subsequent empirical step consisted of interviews with 22 video game players, from which we draw conclusions about games' potential to communicate health themes, illustrate collective health issues and enhance population's participation in public health policies.


The play of Cupak Gerantang is an oral tradition in Bali and Lombok, but this story has integrated and adapted to the people of Bali and Lombok. In subsequent developments, the oral story of the Cupak Gerantang was used in plays in the art of wayang kulit performances in Bali and traditional drama plays in Lombok. These two stories have values that can be understood and accepted by society, such as: educational values, morality values, and ethical values. The figure of Cupak Gerantang in Bali is used as a personification of two brothers who have different faces, if the Cupak character has a bad face, the evil nature is greedy and slander. If the Gerantang character has a handsome face, is well mannered and thoughtful, diligently likes to help respect his parents. Whereas in Lombok the value of the Cupak Gerantang story is symbolic of local community groups and the aristocracy. Cupak Gerantang is understood by Balinese as a figure differently in Bali. Represented as two brothers and sisters. In Lombok the figure of Cupak Gerantang is represented as a characteristic of the Sasak people having a different stratification. Cupak is rude, stiff, arrogant, slanderous, likes to show off. Gerantang is the personification of aristocrats, has a refined nature, is handsome, and likes to work hard and is a noble of Javanese descent.


The current generic delimitation of Lachnaea L. and  Cryptadenia Meisn. was investigated. A multidisciplinary approach was followed. This included a study of the habit, phyllotaxis, morphology and anatomy of the leaves and flowers, pollen morphology and karyology. No major differences were found between the two genera. The range of variation of certain diagnostic characters of these genera is such that the genera merge into each other. It was concluded that the two genera are congeneric and the inclusion of Cryptadenia within Lachnaea is proposed.

An olfactory display for blending many ingredients at any recipe was developed. It consists of microdispensers based upon solenoid valves and surface acoustic wave atomizer. The accuracy and stability were much improved compared with previous olfactory display using micropumps. Then, its blending capability was tested using sensory test such as triangle test. It was found that the scent blended in the proposed olfactory display was identical to the one blended in advance in the liquid phase. Finally, the durability of the amorphous Teflon coating used for enhancing atomization capability was investigated. The durability of the amorphous Teflon coating was much improved when the concentration of silane-coupling agent was modified.


'so that we may learn accurately their powers according to which they take an effect' for ἵνα καὶ τὴν δύναμιν αὐτῶν καθ ̓ ἣν ἐνεργεῖ ἀκριβῶς ἐκμάθωμεν. This may well be a personal stylistic choice, but I find it difficult to understand phrases such as 'many of their body parts heroically treat many conditions' for πολλὰ τῶν μερῶν οὐκ ὀλίγα τῶν παθῶν ἀγωνιστικῶς θεραπεύεσθαι (108.16 and infra). The translation of medical substances is a notorious issue, and since in most cases no definitive answer can be given, it would be desirable to stick to an explicit rationale. But this does not happen here, to the point that on the same page (p. 79) we find Greek names translated into vernacular English ('scammony'), Latin botanical terminology ('Cuscuta Epithymum') and literal translation ('Cnidos berry') just a few lines apart. Μαλάβαθρον is rendered as 'malabathron' at 98.27 and 'Cinnamomum Tamala or albiflorum' at 128.8. While the introduction discusses at length previous scholarship on historical details, the commentary might have been aimed at a readership more familiar, perhaps, with early modern medicine than with the technicalities of Galen's pharmacology. A note, for example, on the exact meaning of the theriac's κρᾶσις, a key Galenic term, here (68.24) misleadingly translated as 'composition' without further explanation, is one such case. Indexes are on the meagre side: there is an index of significant Greek terms mentioned in the introduction and commentary, but unfortunately no comprehensive index (ideally with translation) for the text, which should be a requirement for any critical edition. Some conspicuous omissions such as θηρίον stand out, and there is no comprehensive pharmacological index. It is unfortunate for any book, but especially for an edition, to be spoilt by typos. At p. 11 there are three mistakes in one single quotation from Marquardt's Handbuch. Many are pretty trivial, such as bombycianus (p. 2) and Diocleς (p. 52), or ἀποστάσις (p. 169) and δόξαζω (p. 175), but sometimes the sense is affected (e.g. p. 50, first paragraph), even in the translation itself. (I suspect that 'learn from your native intelligence understanding' for ἐξ ἐμφύτου συνέσεως εὑρίσκεις εὐφυῶς at p. 67 is not deliberate.) Almost 20 such slips can inevitably undermine the reader's confidence.


The rapid increasingly development of technology to encourage people
always to apply the science and technology. This development many apply in the
industry world, one of them is industry eguipment. This technology and science
commonly only increasingly in their operation system, not with other system like
maintenane system and the other.
The increasingly science and technology not balance on this case the
technology of operation system followed by the maintenace system, the maintenace
system will not able to compete with the eguipment technology and the result is the
eguipment will be broken. No matter how advance the eguipment, it still need a
maintenance. As an example in engine Honda GX 160 and water pump Sanchin
SCN � 30. This eguipment can be say are advance in their previous time, but its
now is not. The unprosedural used of this eguipment, finally the eguipment is
broken. therefore is important to maintenace and reuse it�s in a proper way.


To deliver tailored pain science education, assessing children's biopsychosocial pain concepts is necessary. As validated tools are lacking, a new tool is presented, the biopsychosocial pain concept matrix (BiPS matrix), which assesses children's biological, psychological, and social pain concepts in five domains according to the Common-Sense Model of Self-Regulation (Hagger and Orbell, 2003): (1) illness identity, (2) causes, (3) consequences, (4) duration, and (5) treatment. The present preliminary study aims to (1) assess the items' readability and understandability in cognitive interviews with N = 9 healthy children (9 to 19 years, M = 13.78 years, SD = 3.05; 44% female) and (2) pre-test the BiPS matrix within an online survey of N = 27 healthy children (9 to 19 years, M = 13.76 years, SD = 3.03; 56% female). Results revealed difficulties in understanding some items. Children's understanding increased with age. Age, chronic pain status, and pain in the social environment were positively associated with the BiPS total score, whereas the latter explained the most variance in pain concepts of children. Patient-focused methods such as cognitive interviews proved essential in testing the readability and understanding of items in children. Future studies are warranted to further validate the BiPS matrix.


OBJECTIVE: To evaluate the use of misoprostol compared with PGE2 for labour induction at term in terms of cesarean delivery, induction delivery interval, hyperstimulation and neonatal outcome. STUDY DESIGN: Comparative descriptive study SETTING: Department of obstetric and Gynecology unit-I labour ward of Liaquat University Hospital Hyderabad (LUH). DURATION: From 13thAugust 2007 to 12th August 2008 PATIENTS AND METHODS: 100 women between the ages of 20 to 29 years, with term gestation of 37 to 42 weeks, having singleton pregnancy with vertex presentation and bishop score of <6 were selected by Convenient Sampling technique. Women with previous caesarean section, fetal distress, para 5 or more, allergy to prostaglandin, uterine anomaly, cardiac disease, acute asthma or glaucoma were excluded. All information was recorded on preformed proforma and analyzed on SPSS version 11.P value <0.05 was taken as significant . Student T test and Chi square test was used, where appropriate to calculate the P value. RESULTS: Total 100 patients were included in the study. Patients were divided into 2 groups.50 Patients in group A received induction with PGE2 and 50 patients in group B received induction with PGE1. Induction was succeeded in 50% patients who received induction with prostaglandin E2 (In group A) and 74% patient's who received induction with prostaglandin E1 (In group B). 25 (50%) patient's of group A and 37 (74%) patient's of group B delivered by spontaneous vaginal delivery while 25 (50%) patient's of group A and 13 (26%) patient's of group B requires cesarean section. Results showed that prostaglandin E1 is more effective for induction of labour than PGE2 (P<0.004), however there is risk of hyperstimulation and post partum hemorrhage, which need careful monitoring of patient. CONCLUSION: Prostaglandin E1 (Misoprostol) is more effective and safe for induction of labour than PGE2.However the more frequent occurrence of hyperstimulation needs careful monitoring .Due to its high success rate it has reduce the Caesarean section rate and neonatal ICU admission.


On each trial, one of three stimulus events occurred: Presentation of (1) a 500‐cps signal added to a sample of white noise; (2) an 1100‐cps signal added to the noise; or (3) no signal added to the noise. In the detection‐recognition condition, each listener reported whether a signal occurred (detection) and which of the two signals it was (recognition). The listeners' criteria for a YES response were manipulated through instructions. The functions of primary concern were those relating the proportion of correct recognition responses to the proportion of YES responses on signal‐plus‐noise trials, p(YES|S). The ability of listeners to detect the signals when they were not required to make the recognition response was measured in the detection condition. The proportion of correct recognition responses on trials on which the detection response was NO, p(C|NO), was above chance at all detection criteria. The data contradict the predictions made by a threshold model adapted to the detection‐recognition situati...

The power density of a direct methanol fuel cell (DMFC) stack as a function of temperature, methanol concentration, oxygen flow rate, and methanol flow rate was studied using a response surface methodology (RSM) to maximize the power density. The operating variables investigated experimentally include temperature (50-75 °C), methanol concentration (0.5-2 M), methanol flow rate (15-30 ml min-1), and oxygen flow rate (900-1800 ml min-1). A new design of the central composite design (CCD) for a wide range of operating variables that optimize the power density was obtained using a quadratic model. The optimum conditions that yield the highest maximum power density of 86.45 mW cm-2 were provided using 3-cell stack at a fuel cell temperature of 75 °C with a methanol flow rate of 30 ml min-1, a methanol concentration of 0.5 M, and an oxygen flow rate of 1800 ml min-1. Results showed that the power density of DMFC increased with an increase in the temperature and methanol flow rate. The experimental data were in good agreement with the model predictions, demonstrating that the regression model was useful in optimizing maximum power density from the independent operating variables of the fuel cell stack.


: The ferrocene-chelating heteroscorpionate complex [fc(PPh 2 )(BH[(3,5-Me) 2 pz] 2 )]PdMe ((fc P,B )PdMe, fc = 1,1'-ferrocenediyl, pz = pyrazole) catalyzes the addition polymerization of norbornene and norbornene derivatives upon oxidation with [ Ac Fc][BAr F ] (acetyl ferrocenium tetrakis(3,5-bis(trifluoromethyl)phenyl)borate). In situ reduction of [(fc P,B )PdMe][BAr F ] in the presence of a substituted norbornene results in significant decrease of catalytic activity. Addition of one equivalent of oxidant restores the activity. an empirical absorption correction was applied using the package SADABS. The structure was solved and refined using SHELXTL (Brucker 1998, SMART, SAINT, XPREP AND SHELXTL, Brucker AXS Inc., Madison, Wiscosin, USA). Tables with atomic coordinates and equivalent isotropic displacement parameters, with all the bond lengths and angles, and with anisotropic displacement parameters are listed in the cif.


A study was conducted during 1996-99 in a hot sub-humid region of central India to assess forage-based cropping systems with and without hedgerows at different moisture regimes. The 5 cropping systems [berseem (Trifolium alexandrinum L.)-sorghum [Sorghum bicolor (L.) Moench], Sesbania sesban (L.) Merr. as sole crop, Leucaena leucocephala (Lam.) de Wit as sole crop, berseem-sorghum with Sesbania and berseem-sorghum with Leucaena hedgerows] were assessed under 3 moisture regimes (irrigation at 0.5, 0.75 and 1.0 irrigation water (60 mm depth)/cumulative pan evaporation ratio). The green biomass (187 tonnes/ha), dry matter (32 tonnes/ha) and crude protein (4.75 tonnes/ha) yields were significantly higher in a berseem-sorghum alley crop sequence with Leucaena hedgerows followed by the same alley crop sequence with Sesbania hedgerows. The berseem-sorghum alley sequence with Leucaena hedgerows provided green fodder for a longer duration including lean periods. The Sesbania species was found more sensitive to pruning and higher mortality was recorded in Sesbania. Irrigation at 0.5 to 0.75 irrigation water (60 mm depth)/cumulative pan evaporation ratio significantly increased the green biomass, dry matter and crude protein yields. Further increases did not increase the yields significantly. The water use efficiency decreased with increasing soil moisture. Green biomass yield during third growing season was higher (230 tonnes/ha) in the berseem-sorghum crop sequence alley with Leucaena hedgerows irrigated at 1.0 IW/CPE ratio. The annual soil moisture depletion was higher (172.1 cm) in this cropping system.


In this work, with the aid of first-principles calculation, we attempt to clarify whether nanoparticles itself can trap electrons and holes. Polyethylene (PE)/MgO nanocomposite is chosen as a model system. According to the computed adsorption energies, pristine and fully terminated surfaces are stable for the MgO (100) and MgO (111) surfaces, respectively. The electronic structures of several energetically favorable surface configurations are then studied. To probe the behavior of the excess charge, we examined the change in the charge distribution upon electron and hole doping. In the case of ideal MgO, holes are localized within the MgO slab, whereas electrons reside at the PE layer. We also show that the band alignment at the MgO/PE interface and, therefore, the carrier trapping property of MgO, is mainly determined by the intrinsic band edge positions of PE and MgO and the surface dipole of MgO, which can easily be tuned by surface modification.


The direct steam generation (DSG) in parabolic trough collectors is a promising option to improve the mature SEGS type parabolic trough solar thermal power plant technology. According to previous studies the cost reduction of the DSG process compared to the SEGS technology is expected to be 8 to 25 %. All theses studies were more or less preliminary since they lacked detailed information on the design of collector fields, absorber tubes required for steam temperatures higher than 400°C and power blocks adapted to the specific needs of the direct steam generation. To bridge this gap, a detailed system analysis was performed within the German R+D project DIVA. Power blocks and collector fields were designed for four different capacities (5, 10, 50 and 100 MW) and different live steam parameters. The live steam temperature was varied between saturation temperature and 500°C and live steam pressures of 40, 64 and 100 bar were analyzed. The thermal efficiency of the collector operated at temperatures higher than 400°C was calculated based on latest results of SCHOTT's high temperature selective coating development. To assess the different cases, detailed yield analysis of the overall system were performed using hourly data for the direct normal irradiation and the ambient temperature for typical years. Based on these results the levelized costs of electricity were determined for all cases and the most promising parameters were identified.


The possibility of practical implementation of differentially coherent wireless communication scheme based on chaotic radio pulses has been experimentally proven. For this purpose a prototype of that communication scheme was created in the frequency range of 200-500 MHz for binary information transmission and experiments were carried out with it. The obtained results fully confirm the previously developed theoretical principles of scheme functioning and its main properties. Keywords: dynamic chaos, ultra-wideband signals, differentially coherent information transmission, correlation reception.


We consider the problem of multiuser opportunistic fair scheduling (OFS) in downlink MISO systems employing beamforming. OFS is performed on a per scheduling interval basis to achieve fair bandwidth allocation. Transmit beamforming provides TDMA systems with the capability of supporting multiple concurrent transmissions. Since the optimal beamforming scheme can be calculated for a given subset of users, the scheduling problem then refers to the optimal user subset selection to maximize the system throughput subject to certain constraints. We propose two practical multiuser schedulers, and then present discrete stochastic approximation algorithms to select adaptively a better user subset. We also consider scenarios of time-varying channels where the algorithm can track the time-varying optimum. We present results to show the performance of the proposed algorithms in terms of fast convergence, time-varying tracking capability and fairness.


A method for supporting IPv4/IPv6 double stacks by a wireless data terminal comprises the wireless data terminal maps a Modem port and a network driver interface standard (NDIS) port at a user terminal; and the wireless data terminal receives commands of building network connections, a programmed data processor (PDP) context activation request is launched to a network expected to be connected by a user, and network connections are built according to the mapped ports after the network responds to the PDP context activation request successfully. The invention further discloses the wireless data terminal for supporting IPv4/ IPv6 double stacks. According to the technical scheme, users can access the user terminal into an IPv4/ IPv6 network through the wireless data terminal, and the IPv4 network/ IPv6 network can be accessed according to needs.


In mitral stenosis the obstruction to the circulation leads to a build-up of pressure in the left atrium which averages about 25 mm. Hg in uncomplicated cases with critical stenosis requiring valvotomy (orifice 10 x 5 mm. or less). On effort the cardiac output increases and the left atrial pressure rises well above the osmotic pressure of the plasma, even up to 50 or 60 mm. Familiar consequences of this situation include haemoptysis, frank pulmonary cedema, and chronic interstitial cedema of the lungs. As a rule, the pulmonary artery pressure rises passively and maintains a more or less normal pulmonary arterio-venous pressure gradient of about 10 mm. (Fig. 1). The pulmonary vascular


belongs to doctors, and not to the midwife . . . nor the nurse" (l'enseignement du gouvernement de l'enfant appartient aux Médecins, et ni la sage-femme . . . ni la nourrice [p. 166]). Women are, however, capable of undertaking the everyday management of children, provided they follow informed advice. Among the more surprising elements of Vallambert's guidance is his description of the necessity of bathing the newborn several times a day. He contends that changing a child's linens is not sufficient, despite the common practice of lazy nurses (p. 176). His instruction is at odds with conceptions of bathing as potentially dangerous: according to historian Georges Vigarello (Le propre et le sale: L'hygiène du corps au Moyen Age, 1985), dirt had long been thought to provide the body with a protective layer, while cleanliness was primarily associated with the condition of clothing, especially white linen. In addition to offering the modern reader information about medical theory, Vallambert's book suggests that medical knowledge participated in the production of social categories and experiences during the early modern period. In Book 5, the physician separates childhood into distinct age classifications for the purpose of diagnosing disease: (1) from birth to seven months; (2) from the first appearance of teeth to two years; (3) from two to seven years; and (4) from seven to fourteen years (p. 254). The types of illness and required treatment are informed by these divisions. At the same time, Vallambert urges caregivers to train in an orderly fashion the child's senses of smell, touch, taste, vision, and hearing. A nursing child, for example, has an abundance of humidity in his brain, preventing him from discerning either good or bad smells; nurses should therefore bring the child bouquets of flowers, encouraging his acceptance of pleasing odors, while urging him to reject as "abominable" those items with disagreeable scents (p. 189). This and other fascinating advice provides modern readers with a glimpse of the cultural production of the body in early modern Europe. Winn's well-documented edition of Vallambert's book is indeed an important and valuable scholarly resource.


One of the 172 UK cases of equine atypical myopathy (EAM) reported to the Atypical Myopathy Alert Group (AMAG) in 2014 was that of a five-month old male Przewalski horse ( Equus ferus przewalskii ), resident at ZSL Whipsnade Zoo, UK. The foal presented initially with sudden-onset and repeated stretching of the neck as if dysphagic, with progressive weakness (including lying down), sweating and an unresponsive demeanour. General anaesthesia, induced with a combination of etorphine, midazolam and hyaluronidase, was required for each examination and subsequent treatment of the foal. Initial biochemical analysis showed a markedly increased plasma creatine kinase (CK) activity of 105,001 U/L, an increased aspartate amino transferase (AST) activity of 4194 U/L and a mildly increased inorganic phosphorus concentration of 2.35 mmol/L. The foal was unresponsive to treatment and had to be euthanased. Skeletal musculature and the myocardium showed the most significant pathological changes, with histological evidence of rhabdomyolysis, whilst urine organic acid analysis and an abnormal organic acid serum profile were supportive of multiple acyl Co-A dehydrogenase deficiency typical of EAM. This is the first description of EAM in a non-domestic equid.


The primary reason for the development and procurement of the XP-85 airplane was to c ra te a sin& place fighter utilizing the de Havilland Halford H-LB Goblin jet propulsion powerplant. Simplicity of design reduced manufacturing and maintenance problems and allowed rapid construction of a prototype airplane without the necessity of prolonged research programs. Simplicity of design was also reflzcted in a relatively light and small airplane that possessed superlative performance and utility. The XP-80 was completed and delivered to the U.S. Arm): Air Forces Muroc Flight Test Base in only 145 days from the receipt of the Letter of Intent and made i l s initial flight on January 8, 1944. In official perfortnance tests, this airplane achieved the speed of 506 miles per hour, thus becoming the first U.S. airplane to exceed 505 miles per hour in level flight. The purpose of ;his paper is to discuss the dz~~elc!ptn+ent of the Lockheed XP-85 "Shooting Star"


A 73-year-old white female presented for management of her tophaceous gout, pyoderma gangrenosum, and chronic back pain. On exam, there was an incidental finding of reticular, reddish-brown, non-tender, macular, non-blanching discoloration on her entire back, with a few superficial erosions (see Figure). The patient did not know the duration of her rash. It was neither pruritic nor painful. She denied arthralgia, fever, chills, or other constitutional symptoms. She did not have a history of insect bites, recent foreign travel, falls, or trauma. She frequently used a heating pad to alleviate her chronic back pain. Complete blood count, comprehensive metabolic panel, urine analysis, and inflammatory markers were within normal limits.


Daejeonsa basalt in the Mt. Juwang area is composed of 12 lava flows alternate with 9 peperites, and each lava and peperite has variable thickness. Globular peperites yielded in Daejeonsa basalt are mixed basalt clasts with reddish shale. Based on field description, when lava flows over unconsolidated wet shale or injectes into unconsolidated wet shale, peperites were formed at the contacts between lava and shale. Daejeonsa basalt are massive lava flows with rare vesicules: some vesicules are found in upper part of a flow unit. The basalt has mainly pseudomorphs of olivine as phenocryst, and also plagioclase and clinopyroxene phenocrysts in rocks with higher Mg-number. Matrix is mainly subophitic texture, sometimes showing ophitic and intergranular textures due to different cooling rate. Clinopyroxene is augite(WoEnFs), and plagioclase is mostly labradorite(An), but some is andesine(An) and bytownite(An). Oxide minerals are composed of titanomagnetite and ilmenite.

This paper addresses the problem of robust pole placement control of nonlinear systems having multiple equilibrium points and low order dynamics (roll motion of ships) via a dynamic output feedback in which the controller has dynamic states. The design technique is described using linear matrix inequalities (LMIs).pole placement by using LMIs places the close loop poles in appropriate region to have the best response by considering a tradeoff between overshoot of the response, settling time and steady state error. The effectiveness of the proposed technique in control of roll motion of ships is illustrated by simulation results.


The paper specifies our expectations for the "meaning of life". This analysis serves as a background for clarifying the different ways in which evolutionary biology challenges any alleged meaning of life (for example by interpreting our search for such a meaning as a mere adaptation). There are different ways in which people have attempted to stick with the possibility of finding a meaning of life. These are subsequently classified and scrutinized; it is argued that transcendental approaches are the most promising to withstand the challenge of evolutionary biology.


Telecom industry is the most booming sector with fixed line service and wireless cellular service and thereby increasing the GDP of the country. Along with internet BB services other services like IPTV, cable TV, VoIP, and VAS services are also provided by different telecommunication companies. The industry has to play a vital role in this age of information. Now, Media & BB are merged and taken under one umbrella to provide better service to the customers with increasing profit. India is now holding world's second largest telecommunication market and is expected to grow around 10.3% per annum by 2020 to reach US$ 103.9. The demands are increasing, more consumers are getting attached to this sector, and other industrial & educational sectors are incomplete without any communication that can be either data or voice or both. Keeping in mind the growing demands of fast speed, delivery of voice and data, telecommunication industries are doing a revolution in human communication. Different new technologies are getting deployed to bring more consumers, filling rural-urban gap in Tele density, attracting consumers with more speeds and different Value added services. In this paper, the revolution of fixed line services with different technologies & services are discussed based on different telecommunication projects (BT, TDC etc) and Indian BB communication system (BSNL).


The general differential equations of shattering kinetics for mass efflux from fragmented in speedy gas flow drop and for quantity of stripped daughter droplets are derived on a base of mechanism of gradient instability in conjugated boundary layers on drop surface. At some assumptions the system is integrated and laws of parent drop mass diminishing, drop motion, as well as distribution function for stripped droplets by sizes, are obtained theoretically. The time and conditions for full drop breakup are found. Intermediate and final distributions of stripped droplets by sizes are calculated and discussed for various values of definitive parameters of the problem. Comparison of approximated results with those obtained by more precise numerical scheme get evidence of good enough agreement. Some general peculiarities of dispersion kinetics are described.


— Surface and subsurface structural studies undertaken under the Haughton impact structure study (HISS) project indicate that the 23 Ma-old Haughton impact structure, (Devon Island, Canadian Arctic) consists of a central basin of uplifted strata, an inner zone of uplifted megablocks at 3.5–5.5 km radius, a complex, faulted annulus of megablocks at 5.5–7.0 km radius and an outer zone of downfaulted blocks. No evidence of a previously suggested structural multi-ring form was found. The geophysical studies suggest an original diameter of 24 km, slightly larger than previous estimates and the seismic data indicate considerably more faulting in the western portion than has been mapped from surface exposures. Detailed studies of the allochthonous breccia deposits found no major radial variations in lithology and shock levels. The only anomaly is the concentration of highly shocked, cobble-sized clasts in the central area coincident with the maximum gravity and magnetic anomalies. It is suggested that this local component is related to the highly shocked rocks of the central uplift and may have been shed from the uplift during late stage adjustments. There is no visible central topographic peak of uplifted bedrock at Haughton but studies of the post-impact Haughton Formation suggest that the center of the structure subsided 300–350 m soon after formation. Breccia studies also indicate the occurrence of shock-melted sediments, including shales, but no evidence of shock melted carbonates, the most common target lithology. This may be ascribed to the ease with which carbonates are volatilized by relatively moderate shock levels. The large amount of volatiles released on impact helped disperse the highly shocked products leading to the formation of a relatively cool clastic and polymict breccia deposit in the interior, as opposed to a coherent melt sheet. In this regard, the breccia deposit is somewhat analogous to the suevite deposits within the Ries crater. Sedimentological studies indicate that the Cretaceous-age Eureka Sound Formation was present at the time of impact and that the Haughton area has undergone as much as 200 m of erosion since the time of impact.


Donor-derived disease transmission is increasingly recognised as a source of morbidity and mortality among transplant recipients. OPTN Policy 4.0 requires reporting of donor-derived events. In 2009, there were 135 reports of potential donorderived transmission events: 36 reports related to malignancy, 85 reports related to infection, and four reports related to 'other diseases'. The epidemiology and trends of disease transmission since 2005, when mandatory reporting was initiated in the US, will be discussed as well as lessons learned that may result in a lower risk of donor-derived disease transmission.

Objective To review our initial clinical experience of transumbilical single-port laparoscopy in infants with upper urinary tract diseases. Methods In June,2010, we performed transumbilical single-port laparoscopies in 3 patients, including 1 pyeloplasty, 1 heminephroureterectomy and 1 papillary type ureteral reimplantation. Results All cases were completed successfully. No additional trocar was used and no complications were observed. The mean blood loss was less than 20ml. The operative time was 200 min for pyeloplasty,85 min for heminephroureterectomy and 160min for papillary type ureteral reimplantation, respectively. In the pyeloplasty case, the drainage tube and ureter were removed 1 day after surgery. In the last 2 cases, the drainage tubes were removed 2 days post-operatively and urinary catheters were removed 7 days post surgery, respectively. The patients were discharged on the 10th,5th and 8th post-operative day. Double-J ureteral stents were removed 1 month after surgery in the first two patients. After 3 month follow-up, the first patient showed significant alleviation in hydronephrosis,the low pole kidney of the second patient was well and MRU did not demonstrate any reflux in the last patient. Conclusions Applying transumbilical single-port laparoscopic technique in breakage and reconstruct surgery is safe and feasible, with the advantages of less trauma and more cosmetic benefit. However,more specific instruments are required to better apply the technique; difficulties still exist including,limited movement of instruments,suturing and knotting.

This paper explores the role of input and output in language cognition by employing the socio-cultural theory by Lev S.Vygotsky,which conveys human higher mental functioning is constructed in a social,cultural,historical,and institutional context,which is a unity built by different social interactions.Krashen's input hypothesis and Swain's output hypothesis hold different view points on the roles of input and output in lan-guage cognition.Therefore,according to Vygotsky's approach to the understanding learning,the difference hold by Krashen and Swain might be solved by applying Vygotsky's socio-cultural theory.


Abstract In 1863, Emperor Tewodros II of Abyssinia (present-day Ethiopia and Eritrea) took a British consul hostage; five years later, the British sent a punitive expedition. This military expedition continued the brutal tradition of earlier ones and shaped later campaigns in Sudan and West Africa in the 1890s. Typically, a large contingent of non-military personnel accompanied these expeditions and the 1868 expedition to Maqdala was no different. What was unique for Maqdala was the inclusion of a member of staff from the British Museum. We argue that a letter from Charles Thomas Newton, keeper of the Department of Greek and Roman Antiquities, to Sir Roderick Murchison, the president of the Royal Geographical Society (RGS), illustrates that the plunder of cultural heritage was planned. We also argue that the plunder did not go to plan. The inclusion of a man from the museum made this expedition unique in the museum's history. The acquisition of these objects through colonial violence constitutes a strong moral reason for their repatriation from the British Museum and the numerous institutions in which they are dispersed. Understanding the planning involved in their plunder illustrates the entanglement of politics and imperialism with scientific and cultural institutions that constituted the backbone of Victorian Britain.


Background: Ketamine is a potent analgesic and sedative and its analgesic effect persists after its sedation effect(2), but still there is controversy about using ketamine as analgesic due to its psychomimetic adverse effects like hallucinations or nightmares Objectives: the target is to evaluate the effect of pethedine in combination with ketamine to decrease post sedation side effects of ketamine like hallucinations Patients and methods: 150 patients divided into 3 groups,group A 50 patients received ketamine by dose of 1mg/kg.group B patients received ketamine by same dose in combination with midazolam by dose of 0.05mg/kg and group C received ketamine by same dose with pethedine by dose of 0.5mg/kg. Results: the postoperative hallucinations were significantly higher in group A (16 patients, 32%) compared with groups B and C. Also, hallucination was significantly higher in group B (7 patients, 14%) compared to group C (3 patients, 6%) Conclusion: pethedine is better than midazolam to control postoperative hallucinations of ketamine when used in combination for sedation in minor operations Keywords: ketamine,pethedine,midazolam,hallucinations.


This paper probes the function of competition in society through an analysis of the affective landscape that competition creates. Our focus is on education and the connected process of subjectification. We argue that the analysis of competition in human geography needs to advance through abstractions of political economy to the entanglements and relations in which competition is internalised through embodied experience. We conceive competition as a process of organising power relations that work through affective subjectivation and knowledge-production. Those processes are efficiently at work in education, and hence, in young people's everyday lives. It is our suspicion that education is increasingly organised in a way that naturalises competition and marginalises or even closes horizons from other actual and possible modes of social relations and organisational principles. This organising frame links to ideas about learning as an individual endeavour, a linear process that can be pre-planned and measured with representational evidence. To challenge the harmful ethos of personal control and responsibility of young people for their own education and life-paths, we pursue a nonrepresentational analysis of the educational landscape of competition and approach the (learning) human subject as emergent and relationally agentive. Then, also young people's wellbeing needs to be mirrored against the landscape in which it is continually built. As a case for our argument, we discuss two documents linked to Finnish education: an OECD document on education and national competitiveness, and the newly revised curriculum for upper secondary education.


The scotogenic mechanism for radiative neutrino mass is generalized to include neutron-antineutron oscillation as well as proton decay. Dark matter is stabilized by extending the notion of lepton parity to matter parity. Leptogenesis is also a possible byproduct. This framework unifies the description of all these important, but seemingly unrelated, topics in physics beyond the standard model of particle interactions.


To evaluate the long term sustainability of water withdrawals in the United States, a county level analysis of the availability of renewable water resources was conducted, and the magnitudes of human withdrawals from surface water and ground water sources and the stored water requirements during the warmest months of the year were evaluated. Estimates of growth in population and electricity generation were then used to estimate the change in withdrawals assuming that the rates of water use either remain at their current levels (the business as usual scenario) or that they exhibit improvements in efficiency at the same rate as observed over 1975 to 1995 (the improved efficiency scenario). The estimates show several areas, notably the Southwest and major metropolitan areas throughout the United States, as being likely to have significant new storage requirements with the business‐as‐usual scenario, under the condition of average water availability. These new requirements could be substantially eliminated under the improved efficiency scenario, thus indicating the importance of water use efficiency in meeting future requirements. The national assessment identified regions of potential water sustainability concern; these regions can be the subject of more targeted data collection and analyses in the future.


This is the second paper of the series aimed at understanding the ensemble of instanton-dyons, now with two flavors of light dynamical quarks. The partition function is appended by the fermionic factor, $(det T)^{N_f}$ and Dirac eigenvalue spectra at small values are derived from the numerical simulation of 64 and 128 dyons. Those spectra show clear chiral symmetry breaking pattern at high dyon density.


Henry Crew tried to use a Rowland concave grating for stellar spectroscopy with the Lick 36-inch refractor in 1892-93.He did not succeed. A few years later George Ellery Hale planned a similar instrument for Mount Wilson Observatory. His attempt was highly successful, although the spectrograph became quite different along the way. It is instructive to examine the differences between Crew's failure and Hale's success. Crew graduated from Princeton in 1882, and afterward studied physics in Germany for one year, attending lectures by Helmholtz, Kirchoff, and Kayser. Then he returned to the U.S. and became a physicsgraduate student under Henry Rowland at Johns Hopkins University. Crew wrote his thesis on the spectroscopic determination ofthe rotation period of the Sun as a function oflatitude. He used a large laboratory grating spectrograph, and a small, primitive heliometer to bring the solar image to the slit. The result he found, that the rotation period decreases from the equator to the pole, was contrary to the direct evidence from sunspots known at the time, and has been proven incorrect by better spectroscopic measurements since.' After earning his PhD in 1887,Crew stayed in Baltimore for one year as an assistant to Rowland, and then got a job as instructor and head of the physics department at Haverford College, near Philadelphia.? In 1891 when James E. Keeler left Lick Observatory to become director of Allegheny Observatory, Edward S. Holden hired two men, W. W. Campbell and Crew, to carryon the spectroscopic program Keeler had initiated. Holden rightly considered the spectroscopic determination of stellar "motions in the line of sight", (or radial velocities, as we say today) then just getting underway, the most important program of the observatory. Campbell had only an undergraduate education from the University of Michigan in engineering and in the older astronomy of position, but he had good experience in astronomical spectroscopy, for he had worked as Keeler's volunteer assistant the whole summer of 1890. Crew, the first Lick faculty member with an earned PhD, was well-schooled in laboratory spectroscopy, but had practically no astronomical training or experience. Holden wanted Campbell and Crew to work together, to complement each other's skills, but Crew refused, took his fight with the director all the way to the University of California Regents, and won. They ruled that he should be allowed to observe on his own with the 36-inch one night each week. Campbell, given two nights a week for himself, added a photographic camera to the prism spectroscope Keeler had designed as a visual instrument, and began the pioneering research that was to make him famous.' Crew started the program that he had wanted to do from the first, the application of the Rowland concave grating to astronomy.' Gratings form a spectrum by diffraction, an interference effect dependent on the wave nature of


The Wiener–Hopf technique has proved to be an extremely powerful aid to solving problems in diffraction theory, and in particular for acoustic wave scattering. The key step in the procedure is the factorization of the Wiener–Hopf kernel into a product of two functions with (overlapping) semi‐infinite regions of analyticity. However, for complex problems, such as those concerned with the interaction between fluids and structures, the representation of the scalar factors can have technical difficulties which make their computation both slow and delicate. Further, many important models of this type give rise to matrix kernels, for which no exact factorization technique has yet been devised. In this paper, a new procedure is presented to obtain approximate but explicit factorizations of both scalar and matrix kernels. As well as being simple to employ both analytically and numerically, the accuracy of the component factors can be increased almost indefinitely with little increase in numerical effort. Further,...


Context: Companies increasingly strive to adapt to market and ecosystem changes in real time. Evaluating team performance in such changing environments presents a major challenge. Objective: This paper aims to understand how software developers experience performance in a highly volatile environment. This understanding could be used as a basis for guiding formation and maintenance of high-performing teams. Method: A qualitative multiple-case study using thematic interviews was conducted with 16 experienced practitioners in five organisations. Results: We found 33 major categories of performance factors, arranged as a theoretical structure that explains how the subjects experience software team performance. Conclusions: Based on our study, software teams are engaged in a constant cycle of interpreting their performance and aligning it with other stakeholders. Enhancing performance experiences requires integration of soft factors, such as communication, team spirit, and team identity, into the overall development process.


In recent years,especially under financial crisis,the master graduate students are faced with employment difficulties.Graduates' rate of employment in Shaanxi gradually decrease,and the employment pressure is increasing.One reason is that the students' expectations are not realistic and they have deficiency in their comprehensive quality.Another reason is that there is contradiction between supply and demand in employment market.Therefore,the graduate students should attach importance to enhancing core competitiveness.Universities should improve reform and innovation training.perfect management,and strengthen employment guidance.Integrating resources and establishing the information network platform are suggested.


A steel shape-reinforced concrete (SRC) beam, in which a steel profile is encased in an R.C. section, is an essential configuration of steel-concrete composite members. Nevertheless, the precise estimation of shear strength for SRC elements is currently being explored due to the challenges associated with incorporating steel-concrete interaction. This paper establishes a compatible truss-arch model to simulate the shear behavior of SRC beams and predict their maximum shear strength. In the established model, the shear contribution of the R.C. encasement is evaluated using the traditional truss-arch model, and a stress decomposition based on von Mises yielding criterion and strain compatibility is conducted within the steel shape to decouple its shear contribution. Finally, the validity of the proposed model is confirmed using a comprehensive database. The comparison between the experimental and calculated results demonstrates that the established model can effectively and reliably calculate the SRC beams' shear strength.

The modification of the pilot structural model is considered. The mathematical modeling of pilot-aircraft system allowed to get close results to the experiments and to develop the criterion for flying qualities providing the potentiality to predict the influence of the feel system characteristics.

With the advent of big data, cloud computing has emerged as the most on-demand availability of computer system resources, a concept that changed the ways of computing. However, data security remains a problem in making cloud computing vulnerable. Multimedia objects like audio, video, and image are widely used to obscure secret information via steganography. A steganographic system for implanting confidential data in sound utilizing LSB-based calculation which can be used to protect data in the cloud is introduced in this paper. The use of the least significant bit (LSB) of a byte is done to replace a message, further replacing each bit of LSB with a binary message allows us to encrypt an extensive quantity of data. The current research work first carries out a detailed review of various popular steganography techniques, as discussed in the literature. The audio steganography using an improved LSB methodology to safeguard data on the cloud is introduced in the paper. The numerical example demonstrating the encoding and decoding procedure indicates that the improved LSB technique is easy to implement yet difficult to break for intruders.


Using salient examples and on the basis of a comparative analysis of archival data from the Provenance IndexⓇ databases of the Getty Research Institute, this paper identifies the typologies of frames used to display drawings in Roman collections of the 17th and 18th centuries. The phenomenon of exhibiting framed drawings, which has not been fully studied up to now, began during the early 1600s when refined collectors began to display the drawings in their collections on the walls of their residences instead of keeping them in albums or drawers. The chromatic quality of the drawings was enhanced by the frames, which were gilded, black, wood‐colored, or white, and usually quite simple in design, as in the Salvator Rosa type. In such frames, drawings could hold their own with paintings as part of an arrangement of works on a wall. With the dissemination of academic drawings of nudes, instituted by the most important Roman families during the course of the 17th century, framed drawings began to occupy an important position in collections, soon becoming the focal point of entire rooms devoted to a particular theme.


In modern system-on-chips (SOCs), static power consumption represents a significant portion of the chip power. Since static random access memory (SRAM) typically occupies more than one half of the chip area, static power of a SOC is mainly constituted by the SRAMs. Resistive nonvolatile-8T (Rnv8T) SRAM has been proposed to alleviate static power and preserve data in power-down mode and provide fast poweron speed. A Rnv8T SRAM cell is composed of a 6T SRAM cell, two resistive devices, and two transistors. In this paper, we define several memristor-related faults for the Rnv8T SRAM considering electrical defects. Also, a March-like test algorithm which can cover simple SRAM faults and defined memristor-related faults are proposed. In comparison with the existing work, the proposed March-like test needs longer test time, but provides better fault coverage on the targeted faults.


A breakage model is developed to predict the change in particle size distribution of brittle materials that undergo mechanical stress in gas cyclones. The breakage probability depends on the cyclone inlet gas velocity, solids load, particle size, and a material-specific constant. The model is validated with data from experiments on a laboratory gas cyclone with aluminum oxide and iron oxide. The results are applied to calculate the particle size distribution of a chemical looping combustion process with iron ore as oxygen carrier.


Indoor localization has significant growth in recent years. The key requirement to indoor location based-service (LBS) is the availability of floor plans. However, floor plans are difficult to obtain. In this paper, we present a system, Traces-to-Map (T2M), that automatically infers floor plans from pedestrian trajectories collected by smartphones. T2M consists of two parts. First, it takes advantage of collected trajectories to infer a floor plan with wall information. Second, it identifies the region type by considering the standard deviation of moving directions within an area. We validate our method with multiple floor plans. The result shows the T2M system is able to provide a floor plan highly correlated to the real floor plan.


Reversed-phase HPLC with diode-array UV-VIS spectrophotometric detection has been used for identification of natural dyes in extracts from ancient textiles. The parameters for acidic hydrolysis and extraction, such as the type of organic solvent, concentration of acid, and the heating time have been optimised. Under optimum conditions extraction of several natural plants and identification of compounds which could be used as main colorants has been performed. Flavonoids: kaempferol, luteolin, quercetin, and rhamnetin, as well as anthraquinone dyes including alizarin, purpurin, and carminic acid have been found as main chemical components. Some attempts have been made to identify dyestuff mordants, as well as the fibre type by scanning electron microscopy with energy-disperse microanalysis detection.


Amblypygi is a small order of arachnids with features similar to spiders. In Colombia, this order has been subject to low attention, the main investigations are focused towards a taxonomic level. Recently, the geometric morphometrics has proven to be an useful tool for determining shape differences in scorpions and spiders. Due to this, we used geometric morphometrics to determine intraspecific variation in three Colombian populations of Phrynus barbadensis . We digitalized 16 anatomical points over the carapace and 15 in patella by combining landmarks and sliding semilandmarks; the coordinates were aligned by generalized Procrustes analysis. Canonical Variates Analysis was implemented with proportions of re-classified groups and MANOVA. We found significant differences of carapace conformation between populations; all specimens were 80% correctly classified. Statistical analyses of variance (ANOVA) found significant differences in carapace and patella isometric size among populations; the main carapace differences occur in anterior, posterior and right margins. The observed variation could be associated with the environmental differences between localities


In this paper we describe techniques we have adopted to develop a computer-based, outcome-driven simulator to train digital information skills for small unit leaders of the Army's Future Force Warrior program. We begin by contrasting attempts to engender "virtual realism" in simulation based training against attempts to engender cognitive realism by way of the branching storylines at the heart of an outcome-driven simulation. We next present an example of how such an approach might be applied to train digital information skills before turning to a more general discussion of the problems that such an approach entail—namely, crafting an engaging story while minimizing the combinatorial explosion in a branching storyline. We describe how we have dealt with these problems both by streamlining storylines and by decoupling student input from the branching process. Finally, we allude to a software tool we have created that allows the training developer to author and execute such outcome-driven simulations.


We propose a notion of incentive networks, modeling online settings in which multiple participants in a network help each other find information. Within this general setting, we study query incentive networks, a natural abstraction of question-answering systems with rewards for finding answers. We analyze strategic behavior in such networks and under a simple model of networks, show that the Nash equilibrium for participants' strategies exhibits an unexpected threshold phenomenon.


Progress in sunspot seismology is briefly reviewed. New observations of the absorption of p -modes by a sunspot (Bogdan, Brown, Lites, and Thomas 1993) show that the absorption coefficient (averaged over frequency and azimuthal order) increases with horizontal wavenumber to a maximum near k = 0.9 Mm −1 and then decreases monotonically to zero at about k = 1.5 Mm −1 . The absorption along individual p -mode ridges shows a sinusoidal-like modulation, which may be an important feature for comparison with theory. Results for the quiet Sun show no net absorption, but do show apparent emission along p 1 over the same range of k where the sunspot shows its greatest absorption. This behavior, and the overall decrease in absorption at higher wavenumbers, can be explained as an effect of the decreasing lifetime of p -modes with increasing wavenumber k (increasing mode degree l ).

We consider the likelihood ratio test (LRT) process related to the test of the absence of QTL on the interval $[0,T]$ representing a chromosome (a QTL denotes a quantitative trait locus, i.e. a gene with quantitative effect on a trait). We give the asymptotic distribution of this LRT process under the general alternative that there exist $m$ QTL on $[0,T]$. This theoretical result allows us to propose to estimate the number of QTL and their positions using the LASSO. Our method does not require the choice of cofactors contrary to Composite Interval Mapping (CIM). Besides, our method is not affected by interactions.


Diaminomaleonitrile (DAMN) is an electron-rich ligand which is commonly used in the 9 synthesis of purines, amides and Schiff base ligands. In the last case lies the interest in this molecule, 10 given its symmetry and apparent facility to form various ligands and complexes of interest in fields 11 such as organic solar cells and catalysis among others. Nevertheless, its bisubstitution with 12 aldehydes displays certain difficulty due to the double conjugated presence of the nitrile group 13 (C≡N) in its structure, which significantly affect its coordination behavior by modulating the 14 chemical reactivity of its amines. In addition to presenting a practical resume of guidelines for the 15 preparation of different bisubstituted compounds from DAMN, this paper reviews the possibility 16 of attaining a precise characterization by simple spectroscopic techniques. We provide an additional 17 discussion for one of these techniques (commonly reported but often overlooked), given its potential 18 to provide both the symmetry and E/Z configuration of the product. We hope the comprehensive 19 evidence discussed and shown in this review will be helpful to further develop and understand the 20 products derived of this interesting molecule in their broad applications. 21


In this paper, we investigate ultrasound waves passing through a skeletal muscle segment of a specimen. The model is solved using an extension of a method due to Ilya Vekua. An ansatz is made that a solution to a partial differential equation can be found in a form resembling the ansatz of Vekua. It is shown that this is indeed possible. This method is used continuously throughout the paper to find simple representations of the acoustic equations in the different muscle and bone regions.


Based on samples of listed Chinese companies, we use fuzzy-set Qualitative Comparative Analysis (fs/QCA) to explore the relationship between corporate governance and systematic risk during COVID-19. Our findings are as follows: 1) Good corporate governance can slash the impact of systematic risk, and state-owned enterprises (SOEs) are more resistant to systematic risk. 2) Enterprises with both good board and ownership structures can reduce systematic risk by enhancing the benign interaction with stakeholders through information disclosure, a deed that will, on the contrary, increase business risks. 3) If the members of the board have the concept of governance and related professional background, there is no need to increase the proportion of independent directors. 4) The higher the shareholding ratio of the top ten shareholders or the more dispersed overall equity of a company, the more significantly positive effect on stabilizing its operation; a poorly operated enterprise may diminish its operation risks by increasing the proportion of institutional shareholders and inviting them to participate in the company's operation. Based on the above findings, we put forward corresponding suggestions for enterprises and regulators.
