The preparation of conductive nanocomposites of poly(styrene-b-ethylene-co-butylene-b-styrene) (SEBS) triblock copolymers with chemically modified graphene is reported. Graphene has been functionalized with short polyethylene brushes by thiol–ene click chemistry in order to enhance the interactions of the filler with the ethylenic phase of the block copolymer. The presence of graphene modifies the morphology of the SEBS domains, reducing their size and promoting an isotropic distribution of cylinders arranged in hexagonal packing, as shown by SAXS, AFM, and TEM. The elastomeric character of SEBS persists in the nanocomposites with filler content below 1 vol %, retaining high elongation at break. In addition, the percolation threshold for electrical conductivity is found to be slightly above 0.7 vol %, reaching conductivity values of ∼10–3 S cm–1 for ∼2.5 vol % of filler. These materials represent a new class of flexible conductors that open promising opportunities for applications like actuators or bodily...


The authors develop and test variable step symplectic Runge–Kutta–Nystrom algorithms for the integration of Hamiltonian systems of ordinary differential equations. Numerical experiments suggest that, for symplectic formulae, moving from constant to variable stepsizes results in a marked decrease in efficiency. On the other hand, symplectic formulae with constant stepsizes may outperform available standard (nonsymplectic) variable-step codes. For the model situation consisting in the long-time integration of the two-body problem, our experimental findings are backed by theoretical analysis.


A 37-year-old Alaskan logger sustained injuries of the right loin and lower chest when he was pinned between a felled tree and a falling tree. Initial examination at a local hospital showed multiple right nb fractures, right-sided pneumothorax, displaced right transverse process fractures, right flank hematoma, and a decreasing hematocrit. Excretory urography showed no output from the right kidney. Exploratory laparotomy revealed a "massive" retropenitoneal hematoma without other cause of blood loss. He had a transfusion, stabilized, and was transferred to our trauma center, where contrast-enhanced CT showed a 20x 25x 15-cm right-sided retropentoneal fluid collection, small right renal, hepatic, and splenic contusions, and a small amount of extravasated contrast material from the right renal pelvis or proximal ureter (Fig. 1A). The right ureter caudal to the kidney was never opacified. The left kidney and ureter were normal. The patient's blood loss was presumed to be retropenitoneal, and an angiogram was obtained to delineate and treat active sites of hemorrhage. Angiography showed a small renal infarct or contusion, but no active bleeding source. The right renal vein was not visualized. The patient remained hemodynamically stable and was managed nonoperatively. On the ninth day after admission, an adynamic ileus developed. Abdominal CT again showed extnavasation of a small amount of contrast material from the right renal pelvis or proximal ureter, but no change in the size of the retropenitoneal fluid collection (Fig. 1 B). Delayed images obtained 1 2 hr later revealed contrast material had spread to most portions of the large retropenitoneal collection (Fig. 1C). On neither CT examination was the distal two thirds of the night ureter opacified. Right-sided retrograde ureterognaphy showed extravasation of contrast material from the ureter at the level of the right lower pole and no opacification of the renal pelvis. At surgical exploration, the right ureter was found to be completely transected several centimeters distal to the ureteropelvic junction, with the proximal free end displaced laterally. The renal pelvis and hilum were macerated and friable. A night-sided nephrectomy was done when major bleeding from a 1-cm-long laceration of the right main renal vein could not be controlled.

Conclusions: To effectively reduce the work burnout of employees, the psychological capital of employees should be improved while reducing the work pressure of employees. Psychological capital is relatively stable for individuals, and companies can increase their mental capital by improving their resilience and self-efficacy, thereby reducing their job burnout. Background: The hope of revitalizing the nation lies in education, and the hope of revitalizing education lies in teachers. Preschool teachers are the main teachers of kindergarten education. Preschool teachers' teaching behavior has a great influence on children's psychology. Positive and positive behaviors in preschool teachers' educational and teaching behaviors will have a good guiding effect on preschool children, and some "psychic violence" phenomena will cause great harm to children's psychology. Its root lies in the teachers themselves, teachers in the process of teaching and child-rearing in the existence of their own "psychological barriers". These correct ideas are an important reason. Teachers in kindergartens are the first teachers on the way to children's growth, so their mental health is crucial. Through practical exploration and thinking, we find that in the process of teachers' training, we can use the way of educational psychology to explore teachers' "psychological barriers" and guide them. By paying attention to kindergarten teachers' mental health in the process of their daily teaching behavior, kindergarten teachers' mental quality and behavior can be improved. Background: Psychology is the active reflection of subjective to objective, and it is directly affected by factors such as life values. Behind the psychological problems of college students lies the confusion of the values of life. The relationship between the values of life and mental health of college students needs to be studied in depth. To understand the standards of college students' mental health, we should pay attention to the following three aspects; one is the relativity of standards. There is no obvious boundary between mental health and unhealthy of college students, but a continuous process. The second is the overall coordination. To grasp the standards of college students' mental health, we should investigate their internal and external relations based on their psychological activities and strive for overall coordination. The third is the development of psychology. Some psychological problems are unavoidable developmental problems that people encounter in their growth and development. With the continuous growth of individual psychology, they will gradually adjust and become healthy.


OBJECTIVE
To evaluate the safety and efficacy of a new nitinol stent positioning system to assist in the placement of aorto-ostial coronary stents.

BACKGROUND
The stenting of aorto-ostial lesions is technically challenging.

METHODS
We report the first clinical series using the Ostial Pro to assist in the precise placement of stents in coronary aorto-ostial lesions. These results were compared to matched cases performed without the ostial positioning system.

RESULTS
The Ostial Pro is a simple nitinol device with self-expanding legs that are advanced just distal to the tip of the guiding catheter. The nitinol legs prevent the entry of the guiding catheter into the target vessel and align the tip of the guiding catheter. Using the Ostial Pro positioning device, angiographic and clinical success was achieved in 30/30 (100%) cases. Excellent stent positioning was confirmed by angiography (n = 30) and intravascular ultrasound (n = 28). The final true ostial dimension was larger than the stented segment minimum luminal diameter in 30/30 cases. In a matched consecutive cohort of 30 consecutive coronary aorto-ostial stent cases placed without the Ostial Pro, we observed an ostial stent malpositioning in 18/30 (60%) of cases (p < 0.0001 vs. cases performed with Ostial Pro).

CONCLUSIONS
1) The Ostial Pro is a new FDA-cleared nitinol device that is simple to use and effective in allowing the precise placement of stent(s) at the aorto-ostial location; 2) this approach appears to provide an efficient means to assure accurate stent placement and minimal residual stenosis in these difficult-to-treat lesions.

How much are our current soybean yields limited by micronutrients like manganese (Mn)? Many soybean growers have noticed a yellowing (sometimes referred to as "yellow flash") of glyphosate-tolerant soybean following post-emergent glyphosate applications. Glyphosate molecules are known to chelate with Mn, and prior research has suggested that leaf Mn deficiencies are more prevalent following glyphosate applications. Foliar Mn applications have been recommended when leaf Mn levels are low, and these are perhaps most effective when applied about 7-10 days after each glyphosate application. In this presentation, we will review what is known about foliar Mn applications versus banding of Mn at planting, and about the soil factors that limit Mn availability to soybean plants at various intensities of glyphosate application (from no glyphosate at all to 3 applications per year). The Indiana Soybean Alliance has been instrumental in funding this project in 2007 and 2008. Introduction: Recent soybean research in Indiana and a few other states have confirmed that one of the most limiting factors to the achievement of high yields in Roundup Ready (RR) seeding systems is a suspected micronutrient deficiency resulting from applications of glyphosate (Roundup) to soil, weeds, and directly to glyphosate-resistant soybean. Manganese (Mn) concentrations in soybean plants are frequently lower than optimum, particularly in the week or two following postemergence glyphosate application, because glyphosate reduces the uptake and translocation of Mn via physiological immobilization of Mn in soybean plants, and because glyphosate is toxic to soil microbes that reduce soil Mn into a form that is available for plant uptake. Glyphosate exuded by roots of resistant soybean plants, as well as by weeds surrounding the soybean plants, is particularly likely to immobilize available Mn in the rhizosphere of soybean roots. Both root Mn uptake, and translocation of Mn to the shoot, are lower when glyphosate residues are present in soil. Concerns about suspected Mn deficiency following glyphosate application have often been expressed by Indiana farmers to Purdue Extension specialists over the last 10 years of RR soybean production. Some of the early concerns were in suspected low soil Mn soils (perhaps because of unusually high organic content, high pH, or sandy textures). But increasingly, Mn deficiency symptoms are being reported from some of the most productive soils in Indiana. These concerns have multiplied as glyphosate-resistant soybean have grown to more than 90% of the soybean acreage, and as overall glyphosate applications increase with the more recent adoption of RR corn (which may represent more than 50% of the corn acreage in 2008). At first, industry reactions or comments were that the yellow "flash" following glyphosate application was just a temporary phenomenon, and that the RR soybean plants would recover from this without experiencing any yield reduction. However, recent trials by Dr. Huber (Professor Emeritus at Purdue University) and others (e.g., Kansas) have shown large soybean yield increases (up to 18 bushels per acre) by applying foliar Mn at least 8 days following glyphosate application, by applying manganese sulfate at planting, or by adding gypsum at planting (the latter in an attempt to immobilize glyphosate exuded into the root area after glyphosate application). We also know that low plant Mn could be a factor in temporarily delaying soybean N fixation, and in enhancing the severity of certain soybean diseases. We began research in 2007 with the goal of improving the management of micronutrients such as Mn to help achieve the highest soybean yields possible in cropping systems that are ever more reliant on glyphosate for weed control. The research was funded by the Indiana Soybean Alliance in 2007 and 2008. Soil, Environmental, and Glyphosate Factors Affecting Mn Uptake by Soybean Plants: Characterizing the soil environment on which RR soybeans are growing is important. Soil Mn availability, pH, and concentration of other cations can vary tremendously. Even soil moisture following glyphosate application may be an important factor in whether or not leaf Mn deficiencies occur. We know from recent laboratory studies by Alfredo Campos (2006, Ph.D. student of Dr. Cliff Johnston) that soluble Mn availability in cultivated soils is improved with time following flooding, probably because of the increase in microbial mediated reduction of Mn (Figures 1a and 1b). Recording of precipitation events and monitoring volumetric soil moisture concentrations in the two-week period following glyphosate application will be important for understanding the fluctuations in apparent reduced Mn availability to soybean plants. Figure 1. Effects of (a) time from soil flooding, and (b) consequential CO2 release by microorganisms, on reduction of plant-available Mn in cultivated soil. Source: Dr. Alfredo Campos, Purdue University, 2006. (a) (b) Soil pH is probably the strongest factor affecting plant-available Mn in the soil. Soil Mn concentrations have been observed to be higher in corn production than in soybean production 0 0.02 0.04 0.06 0.08 0.1 0 2 4 6 8 10 12 14 Time (days) M n (m m ol L 1 ) 0 0.01 0.02 0.03 0.04 0.05 0.06 0.07 0.08 0.09 0.1 0 60 120 CO2 (ugC-CO2 g) M n (m m ol L 1 ) (Smith, 2006), but even the possible crop rotation influence needs to be interpreted in the context of differential soil pH levels. Most often, visible Mn deficiencies are going to show up first in field areas with high pH. In our recent field studies, we have observed a strong dependency of leaf Mn concentrations on soil pH. The soil pH was measured in each individual plot (about 20 feet wide by 70 feet long), so these results characterize the range in soil pH within the experiment itself. Previous studies on the optimum mode for Mn supplementation in RR soybean: Preliminary research by Dr. B. Gordon in Kansas in 2005 and 2006 has shown that the application of MnSO4 holds considerable promise for RR soybean. In his research, MnSO4 application at planting more than doubled leaf tissue Mn concentration and increased RR soybean yields by about 13 bushels per acre (Figure 2). In this case, the conventional soybean variety appeared to be much more Mn efficient than the RR variety, and higher rates of Mn application to the conventional variety may have been toxic for this environment.

A simple model for tapering optical glass fibers is described and analysed to show that unless the initial conditions have certain spatial singularities, the cross-sectional area cannot be made to vanish in finite time. The model is applied to an industrial process in which the fiber has piecewise uniform temperature.


We describe here the molecular and hematological characteristics of novel frameshift mutations in exon 2 of the HBB gene (in heterozygous state) found in two Argentinean pediatric patients with dominant β‐thalassemia‐like features. In Hb Wilde, HBB:c.270_273delTGAG(p.Glu90Cysfs*67), we detected the deletion of the third base of the codon 89 (T) and the codon 90 (GAG), whereas in Hb Patagonia, HBB:c.296_297dupGT(p.Asp99Trpfs*59), the frameshift mutation was due to a duplication of a 'GT' dinucleotide after the second base of codon 98 (GTG). The Hb Patagonia and Hb Wilde mutations would result in elongated β‐globin chains with modified C‐terminal sequences and a total of 155 and 157 amino acids residues, respectively. Based on bioinformatics and structural analysis, as well as protein modeling, we predict that the elongated β‐globins would affect the formation of the αβ dimers and their stability, which would further support the mechanism for the observed clinical features in both patients.


No industry has demonstrated a greater infatuation with new product "innovations" and their introduction to the market place than has the computer industry. But, despite all the hoopla and excitement surrounding each new advance, it will be demonstrated here that the innovation cycle being experienced is really not so "special." It is, in fact, following a standard product life cycle model which allows any marketer to predict future innovation directions and yields less of a surprise at each new announcement. The model clearly has been operative for such other high tech industries as pharmaceuticals, fibers, and electronic components.


The asphalt mixture's anticracking performance is reduced to solve the problem that the asphalt pavement in the cold area is affected by the continuous and large temperature difference, and the damage features of the fiber asphalt mixture are not clear under the action of large temperature difference cycle fatigue. This article first determines the large temperature difference interval as A, B, C and uses ABAQUS to perform mechanics on the pavement structure in different large temperature difference intervals response analysis.


Purpose. Sports results in powerlifting have been extensively studied, but there is no analysis of the diagnostic sources of criteria for selecting 19–20-year-old athletes. Therefore, it is important to continue the study of factors affecting performance in powerlifting, not only in individual events, but also in the entire discipline. There were two research objectives in the study: firstly, to identify a set of independent (predictor) variables contributing to sports results (outcome variable) in powerlifting using the least numbers of those variables, and secondly, to develop a biometric regression model describing the sports result. Methods. The study group (n = 30) comprised juniors (aged 19.4 ± 0.7) training powerlifting. The following methods of collecting information were used: observation, survey, and analytical methods of diagnostics: analysis of multiple regression functions, and selection of optimal variables with the use of Hellwig's algorithm. Results. The optimal set of variables predicting sports results in junior powerlifting consists of nine features. The integral capacity of the selected information sources reached the value of 0.891. Conclusions. It was confirmed that body composition, special physical fitness, and the technique of movement would constitute the optimum combination of explanatory variables of the model. These characteristics have the highest value as diagnostic and selection criteria and should not be overlooked.


We construct certain new classes of isochronous dynamical systems based on the recent constructions of Calogero and Leyvraz. We show how a Poisson structure can be ascribed to such equations in ℝ3 and indicate their connection with the Nambu structures.


A three-dimensional ocean circulation model, called Princeton Ocean Model (POM), is employed to simulate tides and tidal currents in Liaodong Bay. The nested grid technique is adopted to improve the computation precision. Computed harmonic constants of M-1, M-2 tides at five tidal gauge stations and surface elevations at two oil platforms are compared with those observed, and show good agreements with them. Based on the calculated results, the co-amplitude and co-phase tag lines of nil and M-2 tidal constituents, the residual current field of M-2 constituent, tidal form, tidal Current ellipse and the moving style of tidal current are given. It is found that diurnal tidal constituents have no amphidromic point whereas semi-diurnal constituents have one in the region of interest. Meanwhile, some meaningful results are concluded and presented, which are conducive to a thorough knowledge of the characteristics of tides and tidal currents in the Liaodong Bay.


In this paper, we report a high-resolution and precision acceleration sensor network with potential large sensing capacity, which is based on distributed Bragg reflector fiber lasers. To start with, a transducer based on a T-shaped cantilever beam and an adjustable bearing is theoretically designed and experimentally employed to achieve high sensitivity and wideband frequency response. Second, the beat frequency interrogation system that utilizes super-heterodyne receiver and digital orthogonal phase identifying technology is developed to improve the resolution of the sensors. In addition, assisted with the wavelength/time division multiplexing technology, hundreds of sensing units could be potentially multiplexed in the prototype system. A proof-of-concept sensing network with three acceleration sensor units is established for experimental validation. The sensor network demonstrates a sensitivity of 1.16064 GHz/g with a flat frequency response region from 20 to 200 Hz, corresponding to a noise equivalent acceleration of $\text{17.99}\,{\text{ng/}}\surd {\rm{Hz}}$ at 90 Hz. In particular, the measurement precision of the prototype system has been calibrated as high as 1.305 μg. The proposed acceleration sensor network could benefit potential applications in smart unmanned platforms and seismic monitoring.


With aid of FactSage's thermodynamic analysis software,the effect of addition of fluorine-containing leaching agent on sulfuric acid leaching of blank roasted residue of stone coal was investigated.The results show that addition of fluorine-containing leaching agent can not strengthen direct reaction between sulfuric acid and vanadium in roasted residue.Muscovite is easily dissolved in sulfuric acid solution with addition of fluorine-containing leaching agent due to reaction of aluminum and silicon in muscovite crystal structure with fluorine to form the complex.Hematite is hardly to dissolve in pure sulfuric acid solution,however,with addition of fluorine-containing leaching agent,it is much easier to dissolve and generate solid product of FeF3·3H2O,thus reduce Fe3+concentration in lixivium.


Funding information National Key Research and Development Program of China, Grant/Award Number: 2016YFB1100204; Key Research Project from Science and Technology Commission of Liaoning Province, Grant/Award Number: 2018106004; Shenyang Science and Technology Funded Project, Grant/Award Numbers: 18‐004‐1‐16, 19‐109‐1‐03, Z18‐5‐012 Abstract In this paper, FeCrNiBSiMox (x=1.0, 1.5, 2.0, 2.5) stainless steels were successfully prepared using a laser melting deposition technology, with the aim to investigate the effect of Mo content on microstructure and corrosion behaviors. The results showed that the as‐deposited specimens were composed mostly of α‐Fe and a small amount of (Cr, Mo)7C3, and (Cr, Mo)7C3 existed in the inter‐dendritic (ID) region. As the Mo content increased, grain refinement could be clearly observed, and the area of the ID region increased from 27% to 54%. The low‐angle boundaries accounted for 60–70% of the grain boundaries of the as‐deposited specimens. Increasing the content of Mo improved the microhardness of the as‐deposited specimens from 652 HV to 813 HV. The corrosion current density of the as‐deposited specimens with the Mo mass fractions of 1.0%, 1.5%, 2.0%, and 2.5% were 1.37× 10, 1.02× 10, 6.19 × 10, and 3.06× 10 A/cm, respectively. The as‐deposited specimen with Mo content of 1.5% had lower cumulative erosion loss and erosion loss rate than other as‐deposited specimens. The FeCrNiBSiMox (x=1.5) specimen exhibited excellent resistance to electrochemical corrosion and cavitation erosion.

National and global challenges faced by the Islamic education is increasingly complex, particularly in Indonesia in this global era, faced with problems of social-philosophical failed over. There are two problems faced by Islamic education on the challenges of globalization. 1.) as an opportunity, (globalization) one side will make it easier for Islamic education to access a variety of information easily. Also makes it easier to disseminate Islamic education (dissemination) Scientific products that deliver the benefits of existence for the society.2.) as a challenge, it turns out that globalization not only affects the order of life on a macro level, but also change the life at the micro level, for example against the bond of the social life of the community. That is, the phenomenon of social disintegration, the loss of values tradition, lunturnya customs, manners, and other social deviation in this paper, concludes that, Islamic institutions as a whole still run his role in three basic:the transmission of knowledge and the Sciences of Islam. Secondly, maintenance of Islamic tradition; third, the reproduction of the candidates.


Extracorporeal shockwave lithotripsy is a commonly used method to break down kidney stones in urology clinics. This study aims to investigate whether or not listening to music is effective against state anxiety in patients undergoing kidney stone treatment with this method.


: Artificial photosynthesis, in which solar energy drives CO 2 to produce hydrocarbon fuels, is considered an effective way to solve the increasingly serious energy crisis and mitigate the greenhouse effect. Here, layered porous Ru-loaded and La-doped g-C 3 N 4 nanosheets (Ru-LGCNs) were prepared by one-step Calcination, followed by in situ photoreduction deposition of Ru. The layered Ru-LGCN showed excellent photocatalytic CO 2 reformation of methane performance under visible light, and the generation rates of CO, CH 3 CH 3 , CH 3 OH and CH 3 CH(OH)CH 3 were 133, 154, 251 and 133 μmol·h -1 g -1 , respectively. The reason for the enhanced photocatalytic activity of Ru-LGCN is the synergistic effect of bimetallic Ru and La. It is worth noting that the doped La can provide a good channel for charge transfer between LGCNs and CO 2 . This change in the charge behavior of the transport path is beneficial to break the C=O bonds on the active site La and generate methyl radicals on Ru, resulting in the generation of C2+ hydrocarbons.

This article gathers relevant information that sheds light into the basic principles that motivated the study of the so called Next Generation Networks (NGN). The concepts presented herein include the most recent studies and standards that have been proposed for a suitable operation of NGN. The issues associated to the use of new types of networks and services are illustrated and analyzed; in particular the article illustrates important aspects issues like network architecture, network management and mobility. Additionally, trends for future studies are suggested according to the main challenges of NGN. The current trend suggests that certain key aspects are yet to be solved before establish the actual owner of an NGN network.


Abstract This study explored whether the Waterloo-Stanford Group Scale of Hypnotic Susceptibility Form: C (WSGC) approximates the predictive power of the individually administered Stanford Hypnotic Susceptibility Scale: Form C (SHSS: C). Seventy-one undergraduates were administered the WSGC in a group setting and then tested individually on the SHSS:C. The participants were then hypnotized and tested on four types of targeted hypnotic behaviors sampled from the Revised Stanford Profile Scale of Hypnotic Susceptibility: I & II (RSPSHS:I & II). The following four factors were chosen: (a) cognitive distortion; (b) positive hallucination; (c) negative hallucination, and (d) dreams and regression. The items from these factors were matched on difficulty level. A series of multiple regression and logistic regression analyses were performed. The Waterloo: C was found to match the SHSS: C on predictive power for only one of the four hypnotic factors: "dreams and regression." On the other three factors, the SHSS: C was clearly superior in predictive efficacy. These results mirror previous research (Kurtz & Strube, 1996) that examined other group scales of hypnotic susceptibility in relation to the individually administered SHSS: C. In general, group scales such as the WSGC are poor substitutes for the SHSS: C.


Until recently, it was believed that scarcity of bronze items, especially during the younger periods of the Bronze Age, was typical of the Lublin region area (J. Dąbrowski, A. Gardawski 1979, p. 113; J. Dąbrowski 1982, p. 266). Today such views should be merely memories, however, despite the significant increase of archaeological sources, the territory in question in terms of known material base clearly lags behind, especially when compared with western provinces of the Lusatian culture. Such state of affairs is due to several factors. Primarily, the Lublin region did not provide as favourable conditions for bronze metallurgy as, for instance, Silesia, where since the Early period of the Bronze Age there was an intense inflow of products, and hence the opportunity appeared to become acquainted with the current design, which resulted in the development of local metalworking skills. The proximity of the European mining and metallurgical centres contributed to the fact that bronze metallurgical activity in Silesia developed on a scale, which allowed for the development of local products, and for the production and distribution of surpluses. This could not take place in the Lublin region considering its unquestioned peripherality in respect to the bronze production centres. There was a paucity of raw material here, and local population probably did not show sufficient skills in handling it. Imports, at times from very distant territories, constituted the vast majority of metal products found within the area under consideration (cf. E. M. Kłosińska 2007a; 2009a). Their number depended on the distance to their place of origin, as well as the nature of the contact, thanks to which they arrived in the Lublin region. Undoubtedly, among the most exotic ones were the products coming from northern European areas: Nordic (e.g. the spearhead of the Borbjerg type from Stary Machnów, dist. Tomaszów Lubelski – E. M. Kłosińska 2009b, pp. 247–251, figs. 1, 2; probably belonging to a metallurgist set of items along with a half of a bronze mould for casting axes of the MälarAkozino type – E. M. Kłosińska, P. Sadowski 2014a, p. 22; [2017] in print), or from the east Baltic metallurgical centre (e.g. axes from the vicinity of Kock, dist. Lubartów and Lublin, and items from Pióry Wielkie, dist. Siedlce, Horodyszcze, dist. Biała Podlaska, Radzic Stary, dist. Łęczna and Żółtańce-Kolonia, dist. Chełm – E. M. Kłosińska 2016 [in this volume]). Additionally, metal objects from the Hallstatt zone, such as, for instance, boat-shaped fibula discovered between Topornica and Lipsko, dist. Zamość (E. M. Kłosińska 2014), or fibula with open work hanger and sound-making pendants from a multiple-find set from Wakijów, dist. Tomaszów Lubelski (T. Poklewski 1954) should be included among the exceptional finds. The influx of such individual items could be of an occasional nature and be the outcome of movement of people, who, for example, were engaged in exchange trade, metallurgy, or were other representatives of the elites of the time. Also a chain exchange system should not be excluded in this regard. The amount of imports was increasing significantly in situations when a particular metallurgical centre was relatively close. During the younger stages of the Bronze Age the most important role as the supplier of bronze products for the Lublin region was played by the eastern part of the Carpathian Basin and part of the Dniester region, i.e. the lands within the spread of the Gáva-Golihrady culture metallurgical centre. The concentration of the finds within the south-eastern outskirts of the area under consideration (E. M. Kłosińska 2007b, pp. 232–233, fig. 7) suggests that the Golihrady centre from the territory of western Ukraine could have been more important in this regard for the region. It was from this centre that not only the finished products, for instance, the so-called beak axes from the vicinity of Tomaszów Lubelski and Lubycza Królewska, dist. Tomaszów Lubelski, or the axe from the vicinity of Hrubieszów, dist. Hrubieszów (E. M. Kłosińska 2006, pp. 307, 314), but also bronze raw material in small ingots like the one discovered


The fundamental nature of the interaction between the polymer matrix and the cholate based dissolution inhibitors are being studied by Fourier Transform-IR (FTIR) spectroscopy. It was found that the simple cholate derivatives undergo, in a blend with poly(norbornene-alt- maleic anhydride) and in a blend with the terpolymers poly(norbornene-alt-maleic anhydride-co-t-butylacrylate) and poly(norbornene-alt-maleic anhydride-co-acrylic acid), stronger interaction as seen by shifts in the OH region of the spectra than do blends with dimeric or oligomeric cholates.


The earlier finding of a difference in basophil counts in males belonging to three different ethnic groups, was again investigated in both sexes of these groups. An improved direct counting technique was used. A statistically significant sex difference was found in Whites and Cape CoIoureds, but, significantly, not in Bantu. Bantu males had a lower count (still within normal limits), than Whites and Cape Coloureds; the difference was significant at the 10% but not at the 5% level of significance.


Increasing productivity and reducing manufacturing cost have always been keys to successful business. In machining, higher values of cutting parameters offer opportunities for increasing productivity, but this also involves greater risk of deterioration in surface quality and tool life. During the past decade significant advances have been made in the development of cutting tool materials for machining of 'difficult-to-cut' materials. The cost involved in the production of new turning tools is very high. To overcome this cost factor researchers have tried to bring about modifications in the turning process using existing tool materials. A good understanding of the cutting conditions, temperature generation, failure modes, and cutting forces leads to efficient control of the turning process. The literature reveals that modifications in the tool geometry (such as grooved/restricted contact tools (RCTs) and chamfered/honed edges), applications of cooling techniques, ultrasonic assisted turning (UAT), hot machining, and cryogenic treatment of inserts have led to efficient and economic machining of modern materials used for aerospace, steam turbine, bearing industry, nuclear, and automotive applications. This paper presents a review of the different techniques involved in turning which can supplement the performance of cutting tools for improved economics, good surface finish, and surface integrity during machining of the latest materials.


. In this article we discuss the notion of γ - H ∞ -bounded calculus, γ - m - H ∞ bounded calculus on a half-plane and the weak- γ Gomilko–Shi–Feng condition and give a connection between them. Then we state a characterization of generation of a γ -bounded C 0 -semigroup in a K -convex space, which leads to a version of Gearhart–Prüss on K convex spaces.


This paper focuses on the design of a Stirling engine for distributed solar thermal applications. In particular, we design for the low temperature differential that is attainable with distributed solar collectors and the low cost that is required to be competitive in this space. We will describe how these considerations drive the core design, the methodology for improving the design, and summarize progress made in fabrication of the engine for experimentation. Stirling engines can have broad significance and technological advantages for distributed renewable energy applications. A key advantage of a solar thermal system is that they can incorporate thermal energy storage in a cost-effective manner. In addition, Stirling engine systems are fuel-flexible with respect to the source of thermal energy and unprocessed waste heat can be harvested for CHP purposes as well. The ability to extract unconverted thermal energy for waste heat applications greatly improves the overall thermal efficiency of the system.


ABSTRACT The smell of food is one of the most important factors in assessing its quality. In this study, the influence of drying method on aroma/volatile compounds of oyster mushrooms (Pleurotus ostreatus Jacq.) was evaluated. The drying methods tested were convective drying (CD), freeze-drying (FD), vacuum microwave drying (VMD), and a combination of convective predrying and VM finish drying (CPD–VMFD). The volatile compounds were extracted by solid-phase microextraction and identified by gas chromatography–mass spectrometry. The best fitting model to describe the drying kinetics of the oyster mushroom was Henderson and Pabis model. Thirty-four volatiles in fresh oyster mushrooms were identified, with 3-octanone (2,890 µg/100 g dry basis) and 3-octanol (991 µg/100 g) being the major components. The total concentration of volatiles of fresh mushroom (4,506 µg/100 g) was drastically reduced by all drying treatments, although the highest contents were found after: (i) CPD (50°C)–VMFD (480 W) (245 µg/100 g) and (ii) VMD at 480 W (143 µg/100 g). According to the sensory data, the products dried using the treatment CPD (50°C)–VMFD (480 W) were those closer to the fresh mushrooms.


2-Methoxy- and 2-t-butoxy-5,6-dihydro-2H-pyran react with m-chloroperoxybenzoic acid to give mixtures of trans- and cis-2-alkoxy-3,4-epoxytetrahydropyrans in which the trans to cis ratio is 3:1 and 9:1 for the 2-methoxy and 2-t-butoxy homologues respectively. This selectivity is attributed to the steric effect of the 2-alkoxy group.Lithium aluminium hydride attacks the ring in these cis and trans compounds exclusively at the epoxide carbon remote from the alkoxy substituent to form only 2-alkoxy-3-hydroxytetrahydropyrans. This selectivity of hydride attack is attributed to the polar influence of the two geminal oxygen atoms. Steric factors in this hydride reduction are apparently completely submerged by this polar effect.

Introduction: During and after planet formation, many planetary materials experienced physical and chemical transformations at very high pressures and temperatures that are beyond the limits of most modern experimental techniques. In particular, the behavior of metal relative to silicate is of special interest and may be studied by laboratory shock experiments [1, 2, 3]. The SNL (Sandia National Laboratory) pulsed laser facility is capable of subjecting solid materials to very high temperatures and pressures, comparable to those that may have existed in the deep mantle after the putative Moon-forming giant impact. These conditions have been modeled by [4]. The main objective of this project is to use the SNL pulsed laser facility for experimental studies of the behavior of planetary materials in high-energy density environments that existed during the formation of the Earth. Here we report the measurements of Equation of State (EoS) for different solid materials and mixtures, with the emphasis on metal-silicate interaction during planetary formation. The results of this study can also be used for (i) evaluation of some chondrule-forming mechanisms high intensity radiation produced by the lasers may simulate some energetic events such as solar flares in the early solar nebula; (ii) establishing equations of state for conditions that may exist in the interior of extrasolar "Super-Earths" [5]; (iii) protection against asteroid impacts on Earth. Experimental Approach and Setup: 0.15 1 ns pulses of the Sandia NLS (1064 nm) and ZBL (527 nm) lasers (maximum energy outputs 300 GW/cm to ~ 10 TW/cm, respectively), focused to 1-2 mm spots, were used to generate a shock wave on the surfaces of large monoand polymineralic targets in a vacuum chamber (<10 torr). The experimental setup (Fig. 1) allowed an automatic detection of the arrival of the shock wave, monitoring its propagation through the target, and precise measurement of the target rear surface displacement due to the momentum coupling. The real-time electrooptical recordings of the shock wave propagation coupled with the known irradiation intensity, were used to calculate the front surface radiation pressure (P) and temperature as well as target parameters such as shock wave and particle velocities, rear surface Hugoniot hydrodynamic pressure (PH), front to rear surface pressure gradient, dP/dz, and momentum coupling coefficient, Cm.

In the present article we consider the uniqueness problem for the generalized Radon transform arising in a mathematical model of production. We prove uniqueness theorems for this transform and for the profit function in the corresponding model of production. Our approach is based on the multidimensional Wiener's approximation theorems.


Conventional DC railway traction substations present important limitations that complicate the development of more efficient, reliable and economical electrical power supply systems. In this situation, new technological solutions are necessary. Electronic on-load tap changer transformer (OLTC transformer) enable to adapt the voltage on the catenary depending on the traffic conditions. Besides, the use of electronic tap changers can provide a very fast voltage regulation when needed. The objective of the paper is three-fold. Firstly, to describe the principal characteristics and functionalities of OLTC transformers. Secondly, to present the design process of a full-scale OLTC prototype along with its corresponding control. Finally, to perform an experimental validation of the prototype under laboratory conditions.


ion (Cooper 2005), and particularly one imagined as a set of sweeping exogenous changes, or one coterminous with 'modernity' or 'capitalism'. To achieve this, I have tried, as much as possible, to give a sense of the human interactions, personalities and geographies that constituted the practice and experience of colonial rule in Mukogodo. Doing so, I believe, challenges the view of provincial and district administrations as a mere extension of the executive branch of colonial government (cf. Branch and Cheeseman 2006). While the creation of the Mukogodo reserve and the strict policing of its boundaries chimed with similar segregationist efforts across colonial Africa, administrators in Mukogodo applied these policies with a great degree of discretion. The individual personalities of DOs and chiefs later brought their own idiosyncracies and conflicts to the project of governance in the reserve. Meanwhile, later development schemes emerged to a significant extent out of localised problems and conflicts. Examining the correspondences of administrators and the testimonies of Mukogodo residents alive during this period also highlights the difficulty of reading into colonial practices the direct imposition of metropolitan ideology. Administrators responsible for Mukogodo, by their own admission, acknowledged the difficulty of creating a reserve strictly for 'Dorobo', but pressed on in order to simplify their control of Africans in the interest of the growing white settler population. While there is no doubt that the administration implemented policies that were rooted in racialised constructions of African tribalism, administrators never admit to an epistemological commitment to these ideas in their correspondences with one another, preferring instead to explicitly justify


On-demand wireless links in hybrid data centers can augment the existing network capacity to improve the performance. In the absence of line of sight between the rack transceivers, reflectors have been considered in literature to support high bandwidth, on-demand wireless links within the data centers. Metasurfaces, as a candidate smart reflector technology can be harnessed to bring the intelligence burden to the reflector side which, coupled with the expected low power expenditure, can render the technology a useful alternative. Given the fact that this has not been considered in the literature before, in this paper we highlight the design challenges which emanate from such a consideration and present tools and methodologies which can be utilized to address these challenges, focusing on two problems: wireless link selection to be served by the metasurface, and workload characterization within the metasurface. The former is formulated as an optimization problem with demonstrated effectiveness in minimizing the job completion time. Moreover, the workload analysis reveals a number of interesting attributes, as for example, uneven spatial distribution of traffic on the metasurface's controller network and how this is affected by the metasurface size and location, while the use of beam splitting on the metasurface to support parallel processing and storage functionalities does not significantly affect the incurred workload. Unlike previous work on metasurfaces, which consider mobility-driven reconfigurations, in this paper for the first time we consider data-driven reconfigurations.


The purpose of this paper is to develop a companion robot, which can display facial expressions and recognize human faces. With the 12 degrees of freedom, the robot can generate various facial expressions. In addition, a face-recognition method is proposed based on combining two complementary matching algorithms (a single-image matching algorithm and a sequential-image matching algorithm). We have conducted several experiments to test the developed robot. Experiments showed that facial expressions generated by the robot can be identified well. In addition, the accuracy of the face-recognition is higher than 90%. The developed robot shows great potential to be applied for social interaction with the humans.


This paper explores the use of memoirs and journals as means of understanding two characteristics of intrapersonal communication: the process of selective memory which contributes to personal myth, and the pattern of habitual thinking which confirms self‐identify.


Information of vertical cloud distribution is crucial for the evaluation of the General Circulation Models (GCMs). There were large varieties in the vertical distribution of low-level clouds sorted by pressure and lower tropospheric stability among the models (Watanabe et al., 2011), while retrieved cloud properties from satellites were not converged. Cesana et al. (2016) evaluated three global cloud phase products using the CALIPSO, and showed large differences among the products. In this study, we revisit cloud detection by space-borne lidar. We modified our cloud mask algorithm originally developed in Hagihara et al (2010) to increase detectability of optically thick low-level clouds. We use the attenuated total backscattering coefficient at 0.532 μm for the discrimination the cloudy pixels with the threshold total backscattering coefficient determined by Okamoto et al. (2007) and Okamoto et al. (2008). Remaining noise is estimated by using the data obtained at an altitude of 40 km to avoid contamination of PSCs. In this algorithm, identification of the fully attenuated pixel is newly introduced. The discrimination confirms whether no cloud is in the atmosphere or no information is received. The fully attenuated mask is determined by referring to whether the surface return can be detectable or not. After this cloud mask algorithm is applied, we use the cloud phase discrimination algorithm made by Yoshida (2010), which uses the relation between the depolarization ratio at 0.532 μm and the ratio of two successive attenuated backscattering coefficients at 0.532 μm in vertical, as proxy of extinction coefficient, to distinguish ice and water particles. Here we rely on the following different scattering properties of water and ice clouds. In case of spaceborne lidar observations, depolarization ratio of water clouds is often comparable to that of ice clouds so that the discrimination between ice and water is not possible by depolarization ratio alone. In turn, water clouds generally show larger extinction coefficients than ice clouds for the same depolarization ratio so that the discrimination become possible by using extinction and depolarization ratio. These characteristics are used in the cloud phase discrimination algorithm. We will show the global analyses of cloud fraction and water/ice fraction by application of the new cloud mask scheme and differences for the old and new schemes are discussed.


The variability of isozymes in nine enzyme systems was studied in 25 carob (Ceratonia siliqua L.) cultivars using starch gel electrophoresis of leaf extracts. Five enzymes (phosphoglucomutase, phosphoglucoisomerase, aspartate aminotransferase, shikimic dehydrogenase, and aconitase) were polymorphic, making it possible for the 25 cultivars to be classified into eight phenotype categories. The carob is a leguminous tree native to the Mediterranean basin and southwestern Asia (Smith, 1976). The beans and kernels of this woody perennial are useful for a va- riety of purposes including food, fodder, and as a source of industrial products such as gums, sugar, and alcohol (Carlson, 1986). The major carob producing countries are Cy- prus, Italy, Greece, Morocco, Portugal, and Spain, the latter being the world's largest producer and exporter of carob beans.


This paper reports field experience with a new rapid method to detect and count sulfate-reducing bacteria (SRB) accurately. Test results are available in 15 minutes, compared with the 3 to 4 weeks required with traditional culture methods. This new test method detects SRB that grow poorly or not at all on culture media and gives superior results with such solids samples as biofilms, soils, and sludge.

Cracking of Zirconium-4 Alloys in Acidic Solution under Controlled Potential by Elumalai Govindaraj Dr. Ajit K. Roy, Examination Committee Chair Associate Professor of Mechanical Engineering University of Nevada, Las Vegas The susceptibility of Zircaloy-4 (Zr-4), a leading cladding material for nuclear fuels, to stress corrosion cracking (SCC) has been determined in an acidic solution at ambient and elevated temperatures by using constant-load and slow-strain-rate (SSR) testing techniques. Since the cracking susceptibility of Zr-4 may be influenced by electrochemical potential resulting from the repository environment, SCC testing has been performed under anodic and cathodic controlled potentials (Econt)While no failures were observed at constant load, the results of SSR testing exhibited enhanced ductility but reduced failure stress at elevated temperatures. The corrosion potential, determined by the cyclic potentiodynamic polarization technique, became more active at the elevated temperature. The SCC testing under anodic Econt showed brittle failure, characterized by transgranular cracking, as determined by scanning electron microscopy. The specimens tested with or without cathodic Econt showed dimpled microstructures, indicating ductile failure.


This paper review about The Role of Pricing and Revenue Management in a Supply Chain. Revenue management uses differential pricing to better match supply and demand and increase supply chain profits. Traditionally firms have changed the availability of assets to match supply and demand. Revenue management aims to reduce any supply/demand imbalance by using pricing as a lever a big advantage of using revenue manage is that a change in pricing is much easier to reverse compared to an investment supply chain assets. When it is used properly, revenue management increases firm's profits while leaving valuable customers more satisfied through greater asset availability. Introduction Pricing is an important lever to increase supply chain profits by better matching supply and demand. Revenue management is the use of pricing to increase the profit generated from a limited supply of supply chain assets. Ideas from revenue management suggest that a firm should first use pricing to achieve some balance between supply and demand and only then invest in or eliminate assets. Supply chain assets exist in two forms, capacity and inventory. Capacity assets in the supply chain exist for production, transportation, and storage while inventory assets exist throughout the supply chain and are carried to improve product availability. Revenue management also could be defined as the use of differential pricing based on customer segment, time of use and product or capacity availability to increase supply chain surplus. Another definition for revenue management is an order acceptance or refusal process that employ differential pricing strategy and stop sales tactic to reallocate capacity enhance delivery reliability and speed, and realize revenue from change order responsiveness in order to maximize revenue from pre-existing capacity Revenue management has a significant impact on supply chain profitability when one or more of the following conditions exist:    The value of the product varies in different market segments    The product is highly perishable or product wastage occurs     Demand has seasonal and other peaks    The product is sold both in bulk and the spot market Revenue management technique has been successfully applied to airline, railway, hotel and resort, cruise ship, health care, printing and publishing. Revenue management has considerable potential for manufacturing operations as well. Revenue Management for Multiple Customer Segments Airline seats are good example of market with multiple customer segments. Airline use advance purchase restriction to segment its customer into different fare classes and dynamically adjust their seat capacity assigned to those fare classes as advance sales orders arrive. For instance business travelers are willing to pay a higher fare to travel a specific schedule for convenience and even order at the last minute, while leisure travelers are willing to shift their schedule to take advantage of lower fares. There are two fundamental issues than must be handled to apply the concept of revenue management. First, how to differentiate between two segments and structure its pricing to make one segment pay more than the other. Second, how to control demand such that the lower price segment doesn't utilize the entire available asset. To differentiate between various segments, the firm must create by identifying product or services attributes that segments value differently. For example, business travelers on an airline want to book at the last minute and only stay just as long as they must. In other hand leisure travelers are willing to book far in advance and adjust the duration of stay.  Thus the flexibility on booking and schedule differentiate the business travelers from leisure travelers. For transportation provider the segment can be differentiated based on how far in advance a customer is willing to commit and pay for transportation capacity. Similar separation can also occur for production and storage-related assets in supply chain. To take advantage of revenue management, the supplier must limit the amount of capacity committed to lower price segment even if sufficient demand exist from the lower price segment to use the entire capacity. The basic trade-off here is between committing to an order from a lower price or waiting for a high price to arrive later on. The risks in such situation are spoilage and spill. Spoilage occurs when capacity is wasted because demand from high price doesn't materialize. Spill occurs if higher price segments have to be refused because capacity has already been committed to lower price segment. A current order from a lower price should be compared to expected revenue from waiting for a higher price buyer and order from lower price buyer should be accepted if the expected revenue from higher price is lower than the current revenue from the lower price buyer. To minimize the cost of spoilage and spill, supplier which working with two customer segments can use the following formula. Assume that the anticipated demand


The mechanism of ethinylestradiol‐induced biliary secretion of excess cholesterol, a potential causative factor of cholesterol gallstones, is not yet known. It might be related to altered bile acid metabolism, since the rate of cholesterol and phospholipid secreted into bile is thought to be influenced by the hydrophobicity of the bile acid species secreted. We therefore studied the effect of ethinylestradiol on bile acid metabolism and on secretory relationships between taurocholate and cholesterol/phospholipids in bile. Litter‐matched Syrian female hamsters (80 to 100 gm body weight) were injected subcutaneously with either 0.2 ml per day corn oil (controls) or a pharmacologic dose of 5 mg per kg per day ethinylestradiol in corn oil (EE‐hamsters; n = 6) for 5 days. On Day 6, bile was collected for 60 min (basal secretory rate) via a bile duct fistula after exclusion of the gallbladder. Then, a graded infusion of taurocholate was given for 110 to 130 min. Secretory rates (nmoles. min−1.−1 liver) for bile acids, cholesterol and phospholipids were determined and their mutual "linkage coefficients" (nmoles of secretory increment per 1 nmole of bile acid secreted) calculated by linear regression analysis. EE‐hamsters had higher (p < 0.02) basal secretory rates of cholesterol (0.71 ± 0.21 vs. 0.45 ± 0.10) and phospholipids (5.74 ± 1.04 vs. 4.21 ± 0.73) than controls at comparable bile flow and bile salt secretion rates. Cholic acid pool size and the fractional composition of bile acid species in bile were similar. During graded taurocholate infusion, biliary secretion rates of bile acids were comparable (correlation coefficient = 0.90; p < 0.02) in matched pairs.

Polyscias fruticosa belongs to Araliaceae family widely cultivated in Vietnam. It is a medical plant highly valued recently owing to its diversified therapeutic functions. It's exploited in all parts including root, bark and leaf for medicinal purposes. In the herbal tea production, the final step is normally ended with the roasting in order to improve its flavor and aroma. There's a concern about the detrimental effect of thermal roasting to the stability of phytochemical constituents. In this research, we attempted to evaluate the reduction of total phenolic (mg GAE/100 g), total flavonoid (mg QE/100 g), DPPH radical-scavenging ability (mM TE/100 g), FRAP ferric reducing antioxidant power assay (mM TE/100 g) in root, bark and leaf of Polyscias fruticosa under different roasting conditions. All samples were steamed in vapor for 30 seconds before being dried by convective dryer at 45C for 6 hours to final moisture content around 12%. Then these samples would be roasted in different conditions (125/15; 130/12, 135/9, 140/6, 145/3, C/minutes). Our results revealed that roasting at 135/9C/minutes was appropriate to preserve the most phytochemical constituents.


We examined the relationship between group boundary spanners' work group identification and effective (i. E., harmonious and productive) intergroup relations in 53 work groups in five health care organizations. The data suggest this relationship was moderated by boundary spanners' levels of organizational identification, thus supporting a dual identity model. Limited support was found for the moderating effect of intergroup contact. Finally, if boundary spanners displayed frequent intergroup contact and identified highly with their organization, group identification was most strongly related to effective intergroup relations.


In a strong acidic medium (/>H = 2), (OsCl6)~ and (OsBr6)~ anions react with acridine derivative, forming (OsCl6) (£H)2 and (OsBr6) (¿H)2 complex salts (where L = 3,10 Dichloro Acridine; 3,12 Dichloro Acridine; 3,8 Dichloro Acridine; 4,13 Dichloro Acridine; 3,12 Dimethyl Acridine; 3,13 Dimethyl Acridine; 3,11 Dimethyl Acridine; 3,11 Dichloro Acridine and 3,6 Dichloro Acridine). We found a correlation between the strength of the IHB (Intermolecular Hydrogen Bonding) in these salts and the 7T electronic charge localised on the N atom of the acridines, Qn, (calculated by Huckel's M.O. method). I.R., T.G.A., conductimetric, and magnetic determinations are also reported for the new complex salts.


Microhollow cathode discharge (MHCD) plasmas were generated in gas mixtures containing water vapor at pressures of up to 100 kPa of He or 20 kPa of air. The cathode diameter was 1.0 mm with a length of 2.0 mm. The electrical characteristics showed an abnormal glow mode. Spectroscopic measurements were carried out to examine the plasma and radicals. An analysis of the spectral profile of Hα at 656.3 nm enabled a derivation of the electron densities, namely 2×1014 cm−3 (at 10 kPa) and 6×1014 cm−3 (at 4 kPa) for the helium and air atmospheres, respectively, in the negative glow region. By comparing the observed OH radical spectra with those calculated by the simulation code LIFBASE, the gas temperature was deduced to be 900 K for 4 kPa of He at a discharge current of 50 mA.


Abstract
A critical knowledge source being developed as part of the NLM's UMLS Project is a biomedical thesaurus, called the Metathesaurus. Central to the Metathesaurus will be inter-term relationships, across several biomedical nomenclatures and classification systems, which are derivable from lexical mapping techniques. Previous UMLS research on intervocabulary mapping elaborated these techniques. During the Fall of 1988, they were extended and used to build META-0, a 2,000-concept demonstration Metathesaurus. META-0 was composed primarily of the most frequently occurring MEDLINE index terms from MeSH, and MeSH will be the main source of concepts for META-1, the initial public version of the Metathesaurus. Review of META-0 suggested several refinements to the methodology for building META-1. These include labeling MeSH Entry Terms as lexical variants or synonyms before linking them to other sources. Later work refined algorithmic methods which detect lexical variants in MeSH. The META-1 lexical mapping methodology derives from this research.


Background: The percentage of male teachers in preschools in Taiwan is very low, and thus they have become the disadvantaged minority in preschool teacher training classrooms. Consequently, it is worth investigating the experience of such individuals, and whether the training they receive is both appropriate and adequate. Specifically, should they be taught with teaching methods that are more suited to their educational backgrounds? Or do they have to passively accept the concept that 'real' preschool teachers are female? Aims: The aims of this study are to explore the reasons why males decide to study early childhood care, and to discuss their learning experiences. Sample: Three male pre-service preschool teachers in Taiwan were selected as the research subjects for this study. Method: The data collected for this study included records from official and unofficial interviews and observation notes, to which content analysis was applied. Results: The main reasons why males are willing to enter the realm of preschool education include to start their own business and to get a degree, but interest in the topic itself is not a motivating factor. In their learning experiences, they tend to constantly doubt the value of their jobs as preschool teachers. However, if these men are able to re-position their jobs and develop second specialties, their learning attitudes can become more positive, and they can start to enjoy their careers. Conclusion: There are far more female than male professionals in the field of preschool education. It is thus necessary to provide male preschool teachers with appropriate levels of support, so that they can feel both confident and appreciated in their work, as they still often face considerable resistance from the wider society.


: Decision-making ( DM ) and online activity go hand in hand in many domains of everyday life (e.g., consumer behaviour, financial and investment choices, career development, health and psychological well-being). DM style refers to consistent behavioural patterns in the way different individuals approach DM situations. In this study, we explored the feasibility of inferring DM style from the trace of mouse cursor (or pointer) activity that users generated while performing an online task (the task required no explicit DM). We focussed on maximizing and satisficing DM style. Based on a set of spatial, temporal and spatial-temporal features that were extracted from mouse activity data and on measures of DM style assessed with a conventional self-report questionnaire, we modelled DM style in a supervised machine learning approach. The results show that the models of DM style have between good and high predictive accuracy. Guided by these results, we propose that this mouse-based method might play a useful role in computational recognition of DM style and merits further development. Future work will test the ability of pointer-based models to meaningfully link psychological measures of DM style to objective measures and outcomes of real-world DM situations.


Monoterpenes (MTs) represent an important family of biogenic volatile organic compounds (BVOCs) in terms of amount and chemical diversity. This family has been extensively studied using gas chromatography (GC) and proton transfer reaction-mass spectrometry (PTR-MS). Upon recent advances with Fast Gas Chromatography (FastGC), it was also commercialized with proton transfer reaction-time of flight-mass spectrometry (PTR-ToF-MS) instruments. The combination of both techniques showed promising results in the near real-time separation of isomers, with the need of further improvements. In this study, a FastGC prototype was coupled to a conventional PTR-MS (PTR-QuadMS). Extensive laboratory experiments were performed, in order to test the system's performance and to optimize its operational parameters for MT separation. The detection limit was determined to be around 0.8–1.7 ppbv, depending on the MT. The system was afterwards deployed during a three-week field campaign in a mixed holm oak (Quercus ilex) forest known for its important MT emissions. MTs were measured in the incoming and the outgoing air of dynamic enclosures installed on the branches of four different trees. Three chemotypes of holm oak trees could be distinguished showing consistently different proportions of the emitted MTs throughout the measurement campaign: pinene-type, myrcene-type and limonene-type. Measurements showed a systematic diel variation in emissions typical of light and temperature-dependent, de novo-synthesized VOCs. The results demonstrated the feasibility of the FastGC/PTR-MS system for continuous measurements from dynamic chambers in the field, whereas further improvements would be necessary to lower the detection limit for ambient air measurements.


Objective To compare the clinical efficacy of specially designed and conventional rigid gas-permeable (RGP) contact lens on myopic post-LASIK patients with vision symptoms.Methods Eighteen patients (18 eyes) with visual complaints after conventional LASIK surgery for correcting myopia were randomly divided into two groups,group A (conventional RGP were fitted into) and group B (specially designed RGP were fitted into),to evaluate the fit relationship with RGP.The variety of subjective vision symptoms and wavefront aberrations between with and without RGP were identified by using questionnaire and Zywave aberrometer.Results Specially designed RGP was significantly superior to conventional RGP whatever in dynamic and static RGP fitting and assessment.The root mean square (RMS) value of the total higher-order aberrations in patients with RGP was significantly decreased than that without RGP (P<0.001),no matter it was group A and group B.Among them,the RMS values of spherical aberration,coma,the third and fourth order aberrations in patients with RGP were significantly smaller than that without RGP (P<0.05).The RMS value oftbe fifth order aberrations was significantly decreased in patients of group B after RGP wear (P<0.001),compared with the results that there was a slightly increase in patients of group A,even though it showed no statistical difference (P=0.803).Conventional RGP was the better to decrease the fourth order aberrations and the total higher-order aberrations (RMS values decreased 0.434 ±0.155μ m and 0.615±0.268μ m,respectively),while specially designed RGP was superior in the field of reduction the RMS values of coma and the third order aberrations (RMS values decreased 0.185±0.028μm and 0.753±0.313μm,respectively).There was no difference between two types of RGP in decreasing RMS values of coma and the third order aberrations (P=0.083 and P=0.269).The vision symptoms that troubled the patients of both two groups obviously improved afcer RGP wear (P<0.05).Compared with the conventional RGP,glare and monodiplopia were dramatically relief in the patients with specially designed RGP (P=0.011 and P=0.023).Conclusions Post-LASIK patients with RGP could significantly reduce higher-order aberrations,which lead to improvements in image quality and alleviation of vision symptoms.Specially designed RGP applied to post-LASIK patients could be more easily to get an ideal fit relationship than conventional RGP,and can be used as the effective treatment to those patients suffered from low vision quality after LASLK procedure.

Absorption spectra of solid molecular have been studied to megabar pressures at 85–295 K using Fourier transform techniques and synchrotron infrared radiation. Below 100 GPa, four absorption bands assigned to the Q1(J), Q1(J)+S0(0), Q1(J)+S0(1), and QR(J) excitations were observed at 4000–6500 cm−1. The appearance of a sharp vibron band at 110 GPa and 85 K is attributed to a new phase transformation in normal‐hydrogen. At the 150‐GPa phase transition previously observed by Raman scattering, the frequency of the vibron Q1(J) decreases discontinuously by 85 cm−1 and its absorption increases by three orders of magnitude (at 85 K). Several new absorption features which can be assigned to vibron‐lattice mode combination bands are observed in the high‐pressure phase.

The cooperative binding of gene regulatory proteins to DNA is a common feature of transcriptional control in both prokaryotes and eukaryotes. It is generally viewed as a simple energy coupling, through protein–protein interactions, of two or more DNA‐binding proteins. In this paper, we show that the simple view does not account for the cooperative DNA binding of a1 and α2, two homeodomain proteins from budding yeast. Rather, we show through the use of chimeric proteins and synthetic peptides that, upon heterodimerization, α2 instructs a1 to bind DNA. This change is induced by contact with a peptide contributed by α2, and this contact converts a1 from a weak to a strong DNA‐binding protein. This explains, in part, how high DNA–binding specificity is achieved only when the two gene regulatory proteins conjoin. We also provide evidence that features of the a1–α2 interaction can serve as a model for other examples of protein–protein interactions, including that between the herpes virus transcriptional activator VP16 and the mammalian homeodomain‐containing protein Oct‐l.


is nondegenerate. Firstly, in terms of spherical harmonics, we show that the corresponding linear operator can be decomposed into a series of one dimensional linear operators. Secondly, by making use of the Perron-Frobenius property, we show that the kernel of each one dimensional linear operator is finite. Finally, we show that the kernel of the corresponding linear operator is the direct sum of the kernel of all one dimensional linear operators.


The αυβ3 integrin, also known as the vitronectin receptor, is a heterodimeric transmembrane glycoprotein found on most cells originating from mesenchyme (1). This receptor is often overexpressed in various tumor cells, including osteosarcomas, neuroblastomas, glioblastomas, invasive melanomas, and carcinomas of the lung, breast, prostate, and bladder (1). Many extracellular matrix proteins such as fibronectin, vitronectin, thrombospondin, fibrinogen, osteopontin, and tenascin are known to be involved in interactions with various subtypes of integrins (1). These proteins may contain a variety of motifs for potential cell binding; however, one of the most frequent cell-recognition motifs includes an amino acid sequence of Arg-Gly-Asp (RGD), called "the universal cell-recognition site" (1) or "a versatile cell recognition signal" (2). The binding potency of the RGD motif leads to the development of small homing peptides, whose high affinity to the αυβ3 integrin provides a promising alternative to antibodies in targeting tumors (3). As a result, RGD analogs are widely used in tumor imaging, anti-angiogenesis treatment, and tumor-associated radionucleotides or chemotherapeutic drugs. Some RGD analogs are currently being used in phase II clinical trials (4). These αυβ3 integrin–specific probes will help oncologists improve the delineation of tumors and follow up the progression of anti-angiogenic therapies (4).Gly-Ser-Ser-Lys-(FITC)-Gly-Gly-Gly-Cys-Arg-Gly-Asp-Cys-cross-linked iron oxide-Cy5.5 (cRGD-CLIO(Cy5.5)) is a magneto-fluorescent nanoparticle for multimodal imaging of αυβ3 integrin. This agent consists of three components: an RGD peptide for targeting αυβ3 integrin, two fluorescence probes for optical detection/imaging, and an iron oxide nanoparticle core for magnetic resonance imaging (MRI) contrast enhancement (5). The peptide contains 12 amino acids with an intramolecular disulfide bond to form a cyclic RGD (cRGD). One of the fluorescence probes, fluorescein isothiocyanate (FITC), is attached to the peptide before conjugation to the nanoparticle, allowing for the characterization of peptide/iron ratio and the quantification of cell-associated peptide or peptide-nanoparticle on the basis of the absorption at 493 nm. The other fluorescence probes (i.e., Cy5.5 or Cy3.5) are cyanine dyes consisting of two quaternized heteroaromatic bases (A and A') joined by a polymethine chain with five (Cy5.5) or three (Cy3.5) carbons (6) and directly bound to the nanoparticle (5). These dyes have a cationic character because of the delocalized positive charge of the chromophore, and they possess high quantum yield, good chemical stability, easy conjugation, and high sensitivity (mole extinction coefficient ~ 250,000 mol/cm) (7, 8). The excitation/emission wavelength is 674/692 nm for Cy5.5 and 548/563 nm for Cy3.5, where hemoglobin and water have their lowest absorption coefficient. The difference in wavelength of Cy5.5/Cy3.5 allows for dual wavelength ratio imaging to quantify the components labeled with Cy5.5 or Cy3.5 (9).The nanoparticle contains an icosahedral core of superparamagnetic crystalline Fe3O4 (magnetite) (10) that is caged by epichlorohydrin cross-linked dextran and functionalized with amine groups (CLIO-NH2) (11). These amino groups are used in further conjugation chemistry for attaching the RGD peptides and the fluorescent dyes. The superparamagnetic crystalline includes a sufficiently large single-domain of unpaired spins to generate a net magnetic moment that is larger than the sum of its individual unpaired electrons (10, 12). The main difference between these superparamagnetic nanoparticles and paramagnetic ions such as gadolinium (Gd) is their large magnetic moment unhindered by lattice orientation (13). Thus, they possess a high magnetic susceptibility that results in a significant induced magnetization inside a magnetic field. This, in turn, creates microscopic field gradients that diphase nearby protons and cause T2 shortening (13). CLIO-NH2 has a magnetite core of ~5 nm with a hydrodynamic diameter of 20 nm (11, 12), which can lead to a three- to four-fold increase in T1 relaxivity and a five- to six-fold increase in T2 relaxivity compared to conventional contrast agents such as Gd-diethylenetriamine pentaacetic acid (Gd-DTPA) (10). CLIO-NH2 is suitable for receptor-directed MRI or magnetically labeled cell probe MRI because it is small enough to easily pass through capillary endothelium while retaining superparamagnetism (12). Despite its small size, CLIO still exhibits superparamagnetic properties and is detectable at tissue concentrations of only 50 nmol Fe/g tissue (1013–14 iron particles/g tissue) (10).


While children with medical complexity (CMC) are recognized as an emerging and unique cohort, end of life remains poorly understood and little is known about illness trajectory, decision making and communication experiences for this group of patients and their families.

 This scoping review aimed to describe existing literature on the characteristics of end of life in CMC.

 The study was conducted in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). Electronic databases (MEDLINE, CINAHL, PsycINFO, Scopus, Embase) were searched up to June 2021. Studies reporting children, adolescents and young adults who were at end of life and fulfilled the definitional framework of medical complexity by Cohen et al were included by two independent reviewers. Data on study aims, design, methods, outcome measures and key findings were extracted, followed by quantitative and qualitative analysis of the results.

 Of 1535 publications initially identified, 23 studies were included. In terms of study characteristics, 20 (87.0%) studies were quantitative, 15 (65.2%) were published from 2015 to 2021 and 14 (70.0%) originated from the USA. Study outcomes were categorized into 5 main groups: (1) Place of death (30.8%), (2) Health care use (23.1%), (3) Interventions received or withdrawn (17.9%) (4) Decision making and communication (12.8%) and (5) Others (15.4%). These outcomes were found to be associated with sociodemographic factors and CMC diagnostic categories. Majority of CMC deaths occurred in hospitals and the mean proportion of hospital deaths reported was 68.8% (33.5% to 91.9%). Studies evaluated health care utilization at end of life in various settings including hospice, home care, hospital and the intensive care unit. Interventions studied in this cohort included mechanical ventilation, cardiopulmonary resuscitation, hemodialysis, procedures and medication use. Studies reported that CMC were subjected to more intensive interventions when compared to non-CMC. The 2 main themes which emerged from qualitative studies were that of advance care planning experiences and the unique end of life experiences of CMC and their families.

 This scoping review highlighted the unique characteristics of end of life in CMC and outlined the emerging body of literature as well as knowledge gaps on this topic. A better understanding of this cohort of CMC would serve to inform clinical practice, service development and future research opportunities.


Abstract In 2007, 9,128 fires were actually caused by electrical faults and these fires resulted in 29 deaths and 262 injuries. Arc-faults were one of the major causes of these fires. When an unintended arc-fault occurs, it generates intense heat that can easily ignite surrounding combustibles. But, because conventional circuit breakers only respond to overloads, short circuits, and leakage currents, the breakers do not protect against arcing conditions. This paper presents results obtained in experiments on ignition behavior of wire by series arc fault currents and techniques developed to detect the arc-faults. The developed technique was tested after installation to make sure that they are working properly and protecting the circuit. If the developed arc fault detection technique is applied, the electrical fires caused by an arc-fault can be reduced.

The macro-detritivore gastropod Melampus coffeus plays an important role in energy transfer in neotropical mangroves and, because it consumes tree leaves, it may be a potential ecological indicator of degraded mangrove areas. The objective of this study was to analyse the spatial-temporal distribution and population dynamics parameters of M. coffeus in mangroves and correlate environmental variables with population density, shell morphology and survival. Samples were collected monthly in two mangrove forests with different salinities, located on the north-eastern coast of Brazil. Height, width and aperture height of the animals' shell were measured. The effects of salinity on population density and size distribution in M. coffeus were evaluated in field and laboratory experiments. The results showed that populations of M. coffeus present low density and are composed of large individuals during the dry season in both mangrove forests. These populations are denser and show predominance of small individuals during the rainy season when salinity decreases. The results obtained in the experiments confirm the observations in the field. Animals at extreme sizes (small and large) subjected to different salinity treatments over a moderate period showed higher mortality rates than individuals of intermediate size.


Despite recent enthusiasm for the use of personality inventories in personnel selection, many of the problems cited in Guion and Gottier's (1965) review have yet to be resolved. The validity of measures of broad personality traits is still low, personality tests used in organizations are still poorly chosen, and links between personality and jobs are poorly understood. Personality measures are unlikely to achieve the degree of acceptance given to cognitive tests because of differences in the domains, differences in the tests, and differences in the environments in which cognitive tests versus personality inventories are developed.


The practice of semiconducting nanowires in the photoelectronic nano-devices requires that the band gaps of the nanowires are controllable in the process of the synthesis, where the bandgap of a semiconducting nanowire is highly dependent on its chemical components and the structural parameters. In this work, by performing theoretical calculations at the level of the density functional theory, the band gaps of the MgxZn1-xO nanowires with different contents of Mg and different structural features are extensively studied. Through correlating the calculated band gaps to both the contents of Mg and the structural parameters, we find that the bandgap of a MgxZn1-xO nanowire can be expressed by an empirical formula. Our calculations indicate that this formula is valid for the ZnO nanowires, the alloy MgZnO nanowires, as well as the ZnO/MgxZn1-xO core-shell nanowires. We anticipate that this empirical formula can serve as a guidance for designing a MgZnO nanowire with the desired bandgap in its realistic applic...


Background: Four five ago, the project Preventive Community Treatment started at the Forensic Clinic of Ansbach District Hospital. The aim of the project is to provide professional forensic psychiatric treatment to those patients who have not yet committed a crime linked to a mental illness but show a high-risk profile to commit a severe crime in future (i.e. violence, sexual offences). In this connection, the project focuses on patients suffering from schizophrenia and/or severe personality disorder and has been, for the start, designed for four years. The team is multi-professional and consists of psychiatrists, psychologists, social workers, and nurses who are all trained forensically. This team provides risk assessments to patients who are referred by general practitioners, psychiatrists, or their families. Patients who are regarded being at high risk are treated and monitored voluntarily by offering continuous appointments and doing home visits. The aim of the project is to reduce possible future crime committed by high-risk psychiatric patients. The project was evaluated by a long-term examination of a control group from Erlangen District hospital regarding aggression, severity of illness, outcome etc. The results will show the effectiveness of preventive treatment for psychiatric ill patients with a high risk for violence. Possibilities of a nationwide implementation of the project will be suggested.


The switched reluctance motor can be used in generation mode by selecting the firing angles of the phases. This implies the use of the asymmetrical half bridge Miller converter and position sensors or position estimators. In this paper an alternative current (AC) switched reluctance generator is studied. Generation is obtained by doing resonate each phase inductance with an external AC capacitor. Although the machine only generates periodically in the negative slope of the inductance profile, the set formed with the machine and a resonating capacitor behaves like an AC generator. The energy periodically generated in the negative slope is stored in the capacitor smoothing the pulsed generating process and spread on an AC cycle. So, the set generates when the inductance profile is either positive or negative. Further, position sensors are not used, the magnetic circuit is used in two quadrants and the current profile does not have switching harmonics. The system simplicity suits to battery charge in isolated locations.


A Deep Stratigraphic Test (DST) well is a unique source of stratigraphic information; and provides critical data on drilling conditions, logistics, materials; and subsurface conditions in unexplored frontier areas. DST wells are drilled in locations to gain maximum stratigraphic information but minimize the chance of encountering hydrocarbons. Geoscience drilling, engineering, and logistical programs are designed to evaluate parameters which relate to hydrocarbon potential in a variety of scenarios. This paper reports on DSTR well programs operated by ARCO Alaska, Inc. in the Bering Sea, Alaska. These wells spanned a period of eight years (1976-83) and represented a sustained effort by the petroleum industry to acquire a geologic data base upon which to build a sound basis for the evaluation of future lease sales in the area.


This Research Paper endeavor to observe gig economy and skilled women workers in it. The inspiration and intention of following subject matter is to observe wherein women gig force are greater at ease and extra satisfied with their jobs in comparison to those running in a traditional 8-hour manner because of this number one facts changed into gathered to look the engagement level of professional women gig force in Gig economy and their involvement in it and to become aware of and assess the opportunities and available in Gig systems for skilled women similarly to challenges confronted by way of professional gig women employees employed in education sector in study area Like freelancer, net designing and branding , on-line marketing, pc programmer and coder, content advent Tech-associated offerings.
It has been pronounced by way of various studies that the greater participation of women workers in gig works is due to the ability in dealing with their family and work existence together. But at the same time a number of foremost challenges also has been dealing with by using them. Just like interest insecurity, indiscretion of wages, Social protection, own family obligation, privacy protection and so forth.

The fluorescent lifetimes of a number of europium chelates were determined in solution and as the solid at a number of temperatures and a range of wavelengths of the fluorescent emission. They are compared with the lifetimes of europium fluorescence in other compounds and it is suggested that the variation in lifetime is a result of the ligand—Eu interaction and that discrepancies in the results of different workers on the same compound is related to the manner of preparation of the chelate.


An analytical solution is derived for the two-dimensional, laminar, compressible, planar free jet. The solution assumes constant pressure, specific heats, and unity Prandtl number and accounts for the effects of heat conduction and viscous dissipation in a self-consistent fashion. Exact closed-form expressions are provided for the streamwise and transverse velocities, temperature, vorticity, and dilatation. Temporal instability analyses of these high Reynolds number mean flows indicate that jet-to-ambient temperature ratio exerts a far greater effect on instability growth rates than compressibility. Relative to isothermal conditions, a hot jet flowing into cold ambient fluid is an order of magnitude more unstable and is unstable over a far greater range of wavenumbers. For this hot jet both symmetric and antisymmetric modes are equally amplified whereas isothermal jets have relatively stronger amplification of their antisymmetric modes. A cold jet issuing into a hot fluid is very stable relative to isothe...


In this paper evaluated for the first time in the department of Cordoba, levels of trace elements (Zn, Cu, Pb and Hg) in muscle and liver of eight bats species of the families Phyllostomidae and Emballonuridae, present in a farm with silvopastoral management. The concentration of heavy metals was determined by atomic absorption spectrophotometry with graphite furnace (Pb, Zn, Cd, Cu) and cold vapor (Hg). Heavy metals were found in 24 bats of eight species. The heavy metal content in different tissues followed the order Zn> Cu> Pb> Hg for most species. The concentration of heavy metals in liver and muscle showed statistically significant differences. Contamination by heavy metals in bats associated with a silvopastoral system may be related to the use of agrochemicals, pesticides and phosphate compounds for this agro-ecosystem management.


We report a high jugular bulb with Mondini dysplasia visualized by high resolution CT and Magnetic Resonance Angiography (MRA) in a 12-year-old girl. High resolution CT showed the empty cochlea and high jugular fossa . MRA performed for the purpose of confirming diagnosis of a high jugular bulb and sigmoid sinus enlargement in the left side , and hypoplasia of the sigmoid sinus in the right. Audiogram of the left ear showed a profound deafness, and ABR showed no response. Vestibular function was examined by the caloric test, eye tracking test, opto-kinetic pattern, stepping test , and stabilometry. The results were as follows: 1) We speculate that a high jugular bulb with Mondini dysplasia may be due to interruption of development at early fetal life, and that high jugular bulb is caused by hypoplasia of the contralateral sinuso-jugular system. 2) Vestibular dysfunction was compensated for by contralateral vestibular function, and the extrapyramidal and pyramidal tracts.
