Fanie Snyman, from the University of the Free State in Bloemfontein, South Africa, is one of the best known researchers in the field of Old Testament prophecy. He published articles on Jeremiah and on some of the so-called Minor Prophets, viz. Amos, Obadiah, Habakkuk, and Zephaniah. The bulk of his studies in this area, however, explore Malachi. The number may not be complete, but I counted seven essays on nearly every pericope of the short book. The list begins with a study on "Antitheses in Malachi 1:2-5", which appeared in the Zeitschrift fur die alttestamentliche Wissenschaft (1986), and ends with a paper on "Malachi 4:4-6 (Heb. 3:22-24) as a point of convergence in the Old Testament or Hebrew Bible", published in 2012 in HTS Teologiese Studies/Theological Studies. Obviously, his articles covered the entire text of the book.


Biofilm growth inside paper mill water lines is a major problem, since bacteria can alter the quality of paper and damage machinery. To fight them, large amount of chemical substances are usually applied, without a link to the real biofilm development. Thus, there is a strong need for a monitoring technology able to provide an early warning, to optimize cleaning treatments. Several biofilm monitoring approaches have been proposed over the years, but their application has been very limited. Recently, a new technology able to measure biofilm electrochemical activity was successfully employed in different fields. In this work, the performances of this sensor for freshwater applications and, in particular, for paper mills have been evaluated both in lab and in a real case. The results show that, coupling standard biocide treatments with advanced on-line monitoring technologies, it is possible to keep track of chemicals and of their effectiveness toward biofilm.


In "The Angler," published in The Sketch Book of 1820, Washington Irving tells how he gave up fishing for reading. Having been seduced to attempt angling by Walton's Compleat Angler, he finds only frustration: I hooked myself instead of the fish; tangled my line in every tree; lost my bait; broke my rod; until I gave up the attempt in despair, and passed the day under the trees, reading old Izaak, satisfied that it was his fascinating vein of honest simplicity and rural feeling that had bewitched me and not the passion for angling. (321)" Irving's confusion of the pleasures of reading the Angler with the pleasures of angling itself is a comic variation on a commonplace of commentary on Walton's work, the comparison of reading and fishing. In the most thorough critical exploration of the analogy between the two activities, Anna Nardo argues that the Angler offers its reader "a unified aesthetic experience of reading" (303) that "recreates" the experience of the unity with nature that rewards the fisherman. Nardo's argument is based on a general theory of literary "play," derived from theorists such as Huizinga, Csikszentmihalyi, and Winnicott. According to Nardo, learning about the art of angling through reading provides an opportunity for play similar to that offered by fishing itself, and the vicarious experience can provide rewards fundamentally the same as the actual, especially since both are activities pursued not "for use" but "for joy"(309). However, a closer examination of the structural and affective similarities of fishing and reading, as both are represented in the Angler, not only reveals additional parallels between the two activities but, I will argue, suggests a coherent theory of narrative of experience, which the Angler itself tries to implement, and which might be applied more broadly to explain the experience of other narratives. Both Venator, the initiate angler in the text, and the reader of the text are positioned by the narrative as the objects and auditors of the discourse of Piscator, the evangelist of angling in whose voice most of the book is spoken. Like Venator's experience in the narrative, the reader's experience of the narrative takes the form of a pastoral retreat and return. And for both Venator and the reader it is die discourse itself, even more man the fishing, that "beguiles time," thereby offering a vision of salvation from worldly care. Thus the Angler presents not only a "Discourse . . . of fishing," as its title page promises, but discourse as fishing. Such students of die Angler-as John Cooper and Bevan Jonquil (who, as opposed to students of angling and other appreciative readers, have been surprisingly few) have noted its blending of pastoral and georgic elements. Its setting is pastoral: the open, uncultivated fields through which the fisherman tramps. Like the shepherd, the angler possesses tide to no land, yet may be said to possess its spiritual fruits in a way the wealthy owners of the estates whose streams he fishes do not. And, as with many Renaissance pastorals, the plot of the Angler describes an escape from the world of society and urbanity, into a rural world whose values contrast with those of the city and court, and a return at the end. As georgic, the Angler offers practical advice on how best to harvest nature's bounty.1 In the georgic tradition the realms of city and country, while distinct, more often complement than oppose one another: compared with the shepherd (who in pastoral literature is more likely to be portrayed at leisure than at work), the farmer more actively shapes the raw materials of nature to human ends and engages in a more regular commerce with the market in town. The georgic is much more likely than the pastoral to be concerned with the interactions between the two realms, in negotiating with the urban world rather than fleeing it. Thus the georgic is less susceptible to the charges of escapism often leveled against the pastoral. …


The crisis definition is offered as the process where stages of the potential, latent, sharp surmountable and sharp insuperable crisis are allocated. For each of the crisis stage an orientation and structure of anti-recessionary procedures are defined. The conclusion on the objective necessity of complex character of realization of anti-recessionary procedures is drawn.


BACKGROUND The benefits of cardiac rehabilitation (CR) are already well established; however, such intervention has been underused, mainly in low- and middle-income countries. AIM To compare adherence, effectiveness, and cost of a home CR with the traditional CR (TCR) in a middle-income country (MIC). DESIGN Single-blind randomized control trial. SETTING A university hospital. POPULATION Individuals with coronary disease that were eligible were invited to participate. A randomized sample of 51 individuals was selected, where two participants were not included by not meeting inclusion criteria. METHODS The home-CR group participated in health education activities, carried out two supervised exercise sessions, and was instructed to carry out 58 sessions at home. Weekly telephone calls were made. The TCR group held 24 supervised exercise sessions and were instructed to carry out 36 sessions at home. RESULTS 49 individuals (42 male, 56.37±10.35years) participated in the study, 23 in the home-CR group and 26 in the TCR group. After the intervention, adherence in the home-CR and TCR groups was 94.18% and 79.08%, respectively, with no significant difference (P=0.191). Both protocols were effective for the other variables, with no differences. The cost per patient for the service was lower in the home-CR (US$ 59.31) than in the TCR group (US$ 135.05). CONCLUSIONS CR performed at home in an MIC demonstrated similar adherence and effectiveness compared to the TCR program, but with a lower cost for the service. The results corroborate the possibility of using home CR programs, even in MICs, after exercise risk stratification and under remote supervision. CLINICAL REHABILITATION IMPACT Home-CR can contribute to overcome participants' barriers with compatible cost. Home-CR is effective in improving functional capacity and risk factors control. Perform risk stratification and remote supervision are essential to offer Home-CR.


Remote surveillance system is the use of cameras to monitor properties and assets from a remote location. It is used as an asset protection device for areas where it is not possible or practical to install a cable network. However, transmitting a real time video over an ad- hoc network creates a video interruption because wireless link in an ad-hoc network are broken frequently due to noise signal, attenuation and nodes mobility. So we have designed a multimedia route repair routing protocol (MRTP) for efficient route repair mechanism and to check the quality of the link between each nodes in the wireless Network, which simulated using NS2 simulator and We have combined Advanced video coding, H.264 with the multimedia route repair protocol for the efficient video transfer between the mobile nodes in wireless Network.

In this paper, it has been attempted to highlight the features of the five years administration system and the continuity and changes that took place during the Italy administration in the area. During the Italian Occupation, Limmu was the administrative center of the Italians for the Oromo of Western Anger River. Surprisingly, Limmu Oromo during the Italian occupation (1936-41) fought both the Italians and the naftana settlers. According to genuine sources, during Italian Occupation (1936-1941) the naftana-gabar system was removed in the study area. Accordingly, the most important event of this period was that the Limmu Oromo were librated from the naftana rule by their leader, Fitawurari Duguma Jaldeso. Relatively speaking, according to many written materials and oral sources, the Italian administration was better than the former administration system in Limmu. The Italian Occupation was a land mark in the history of the gabars in the surrounding region in general and that of Limmu in particular. Soon after they stationed at Ayana (the capital of Gidda-Kiramu Woreda), the Italian military station for the areas between the Abay and Angar, Italians successfully abolished the gabar system in the area. But, in the post-Italian Occupation period, the pre- 1936 situation was restored without much change in Limmu from 1941 continued till 1974. These and other related situations were well assessed in this paper


The paper is concerned with the issues of modeling dynamic systems with interval parameters. In previous works, the authors proposed an adaptive interpolation algorithm for solving interval problems; the essence of the algorithm is the dynamic construction of a piecewise polynomial function that interpolates the solution of the problem with a given accuracy. The main problem of applying the algorithm is related to the curse of dimension, i.e., exponential complexity relative to the number of interval uncertainties in parameters. The main objective of this work is to apply the previously proposed adaptive interpolation algorithm to dynamic systems with a large number of interval parameters. In order to reduce the computational complexity of the algorithm, the authors propose using adaptive sparse grids. This article introduces a novelty approach of applying sparse grids to problems with interval uncertainties. The efficiency of the proposed approach has been demonstrated on representative interval problems of nonlinear dynamics and computational materials science.


In the previous article (part 1), the procedure for setting the computer screen was discussed by using Adobe Gamma in the control panel. Adobe Gamma is also found on the drive where the system is installed. Click on Program Files > Common Files > Adobe > Calibration > Adobe Gamma.cpl. Double click to launch the gamma control wizard. On a Macintosh the Apple Calibration Utility can be used. The merits of using ink jet printers were also discussed. Merits include low cost (though costs escalate with the purchase of cartridges), high quality prints from any application, and the technology of a fine spray with higher image resolution as opposed to a laser jet printer and Tektronix Phasers (these printers separate images into dots at compromised resolutions).


Andrew Allcock travelled to Switzerland to attend the company's annual event and catch up on business and technology developments. Industry 4.0 was the main theme, although new machines were imminent, but kept under wraps


Digital network language lab has a powerful function and advantage in teaching, and has begun to gradually replace the traditional language lab. This paper introduces the characteristics and advantages of the digital network language lab, also analyzes the possible problems in the process of using, and puts forward the corresponding countermeasures: to set up a team of laboratory management with high quality; to strengthen the professional quality of teachers and improve the utilization of language lab; to increase the security investment; etc.


The goal of this paper is to provide design criteria for moorings proposed for long-term ocean observatories that use electro-optical-mechanical (EOM) cables and to identify the parameters that affect their dynamics. The EOM cables are much stiffer than traditional mooring lines, and therefore, the moorings may experience higher loads under most environmental conditions if not designed properly. Two designs that provide geometric compliance yet keep all the cable in the water column are considered. One of the designs uses a single subsurface float (SSF) with an "S-tether" positioned above it. The other design uses distributed buoyancy to create an S-tether in the lower half of the mooring line. Both designs use an elastomeric snubber hose attached inline just below the buoy. The maximum tensions in the hose and at the anchor and Raoof's contact stress-slip parameter at critical locations are used to evaluate the designs. The present results show that the most important design parameter in terms of the maximum tensions is the length of the mooring, the most important parameters in terms of the bending fatigue damage is the length of the buoyant section and the distribution of cable floats, and the most important design parameter in terms of the dynamic motion of the cable is the length of the snubber hose. In the design with an SSF, it is shown that there exists an optimum S-tether length that minimizes the maximum tensions for a given SSF depth. The general rule of thumb that the S-tether be about twice the depth of the SSF breaks down when the SSF is placed near the surface. In general, the design with an SSF should be used if a small watch circle and small tension in the snubber are required. The design without an SSF is preferred if small overall tension along the length of the mooring is required, if the bending fatigue failure is of concern, and if a longer smooth section of the cable below the surface buoy for use with a profiler is required. In both designs, the snubber length should be at least 30 m so that the dynamic motion is kept reasonably small


The article presents the results of the long-term introduction of collection plants of the arboretum of the Altai Botanical Garden. The authors of the article collected woody introduced species for primary testing from North America, Siberia, the Far East, China, Japan, Central Asia, and Europe. The objects of the study were 643 species, forms, varieties of woody plants from 102 genera and 40 families of gymnosperms and angiosperms taxa. Plants were collected by seed material, living samples and green cuttings. The assessment of the introduction resistance of the garden arboretum gene pool was given based on complex indicators of plant viability according to the data of long-term experimental research. To determine the indicators of viability, adaptation, the method of phenological observations in botanical gardens was applied. The prospect of taxa for use in the landscaping of the region was determined according to the integrated scales of M.P. Kosarev, P.I. Lapina, S.V. Aristova. According to the complex of biological and economic characteristics, 370 species, forms, varieties of coniferous and angiosperms are recommended for use in landscaping of region. Materials for monitoring the introduction resources of the arboretum of the Altai Botanical Garden can be used to expand the introduction work in Kazakhstan and in regional green construction.


Ten years ago, an exhibition with the title Fotografie nach der Fotografie (Photography After Photographs) caused a sensation. It thematicized the influences and changes photography had experienced since the spreading of digital technologies and presented a selection of artistic work that had originated from within this context. Making reference to various contemporary standpoints and individual works, the contribution deals with the question of to what extent what at the time was perceived as an enormous break in the history of images and media can today be described as a mesh of interdependencies, differences and continuities.


Computed Tomography (CT) is a widely used technology that requires compute-intense algorithms for image reconstruction. We propose a novel back-projection algorithm that reduces the projection computation cost to 1/6 of the standard algorithm. We also propose an efficient implementation that takes advantage of the heterogeneity of GPU-accelerated systems by overlapping the filtering and back-projection stages on CPUs and GPUs, respectively. Finally, we propose a distributed framework for high-resolution image reconstruction on state-of-the-art GPU-accelerated supercomputers. The framework relies on an elaborate interleave of MPI collective communication steps to achieve scalable communication. Evaluation on a single Tesla V100 GPU demonstrates that our back-projection kernel performs up to 1.6× faster than the standard FDK implementation. We also demonstrate the scalability and instantaneous CT capability of the distributed framework by using up to 2,048 V100 GPUs to solve 4K and 8K problems within 30 seconds and 2 minutes, respectively (including I/O).


We study the potential of the linear collider (LC) with {radical}(s)=0.5 TeV, linac-ring type ep collider (LCxLHC) with {radical}(s)=3.74 TeV, and the large hadron collider (LHC) with {radical}(s)=14 TeV to search for excited neutrinos through transition magnetic type couplings with gauge bosons. The excited neutrino signal and corresponding backgrounds are studied in detail to obtain accessible mass limits and couplings for these three types of colliders.


The invention discloses a reinforced type aluminum-copper-based composite friction material which is prepared by carrying out procedures of raw material mixing, hot press molding and curing, wherein the raw materials comprise the following components in parts by weight: 15-20 parts of cast aluminum alloy ZAlSi8MgBe powder, 8-10 parts of copper alloy Cu30Ni15Mn powder, 8-10 parts of silicon carbide, 6-8 parts of potassium titanate fiber, 5-6 parts of aramid fiber, 5-6 parts of zirconia, 3-4 parts of tetrapod-like zinc oxide whisker, 1-2 parts of molybdenum disulfide, 1-2 parts of barium sulfate, 1-2 parts of tungsten carbide, 1.5-2 parts of nitrile rubber and 1-2 part of nano-titanium dioxide. According to the reinforced type aluminum-copper-based composite friction material, aluminum alloy and copper alloy are adopted to replace steel in a base material, as the heat radiation of the aluminum alloy and copper alloy is greatly higher than that of ordinary steel, the heat generated from brake friction can be radiated in time, the temperature of the surface of a brake pad is reduced, the high-temperature head fading property is alleviated, and the wear rate is small; and meanwhile the experiment shows that the noise frequency is less than 450Hz, so that people cannot hear conspicuous noise in an automobile.


The wind farm layout optimisation problem involves finding the optimal locations for wind turbines on a wind farm site in order to minimise the so-called "wake effect". The wake effect is the effect of turbulence on wind velocity produced by a turbine's rotating blades. This results in reduction in power production and increased fatigue in downstream turbines inside the wake. This paper uses wind velocity data produced from expensive Computational Fluid Dynamics (CFD) simulations of a rotating wind turbine at various incoming wind speeds to generate ground truth wake data, and explores the ability of machine learning algorithms to create surrogate models for predicting the reduced-velocity wind speeds inside a wake. In an extensive evaluation, we show that (i) given data from a CFD simulation, we can construct a model to interpolate wind velocity inside the wake at any arbitrary 3D point with high levels of accuracy; and (ii) given data from several CFD simulations (the training data) we can also accurately predict wind velocities in the wake of CFD simulations that we have not yet run (i.e. we can extrapolate to simulations where the incoming wind speeds are different to those in the training data). The net effect of these findings are that they pave the way towards the construction of novel and improved wake models for wind turbines, which in turn can be incorporated into existing algorithms for solving wind farm layout optimisation problems more accurately.


The purpose of this research is to challenge the modernism view and principles by revealing the negative issues and impacts of technology as portrayed in Mosquitoes (2017) play script written by Lucy Kirkwood. The research uses a qualitative method in showing and elaborating the findings. To challenge the modernism view, the research undertaken uses postmodernism lens with Jean Baudrillard's theory of simulation, simulacra, and hyperreality in analyzing situation and forms of those concepts which are hidden in the text. This research discovers that the advancement of technology makes the characters very dependent on technology itself, especially on computers, mobile phones, and the internet. However, this technological dependence is not accompanied by significant benefits as modernists assert, but rather tends to produce detrimental effects for the characters. The detrimental effect of using technology is that the characters are trapped in a world of hyperreality manifested in the form of fake news and cybercrimes, causing some serious problems that must be dealt with by them since the boundaries between real and fake have collapsed. This cause-effect regarding technology and hyperreality emphasizes a paradox that technology which is supposed to be controlled by humans yet control humans themselves because technology takes a role in shaping the way humans think and behave. In essence, the findings of this research reinforce that the positive view of modernism on advancement in human civilization is not fully materialized.


Since its introduction, Prahalad and Bettis's concept of dominant logic has informed
a variety of scholarly conversations in management and strategy research. However,
scholars have interpreted dominant logic in different ways, emphasizing different aspects, such as managerial mindsets, administrative tools and management functions, as
defining elements. Similarly, empirical studies have captured various aspects, such as
meanings of entrepreneurs, observable strategic decisions and business model similarity, as indicators of dominant logic. Consequently, the concept lacks analytical clarity,
and it is difficult to compare or generalize findings from this diverse set of studies.
The aim of this review is to improve conceptual clarity by analysing, comparing and evaluating the existing interpretations and assessments of dominant logic in 94 studies.
In the first part of the review, by disentangling the interpretations of the concept, we
show that dominant logic consists of four defining dimensions: (i) shared mental models;
(ii) values and premises; (iii) organizational practices; and (iv) organizing structures. In
the second part, we reassemble dominant logic into an integrative model and theorize about how these dimensions operate in concert to produce a firm's dominant logic.
Thus, our main contribution is a clarification and synthesis of the literature, which
comes with implications on how future research can conceptualize and operationalize
dominant logic more consistently.


Purpose
The purpose of this study is to look into the hygroscopic and tribo-mechanical properties of a polypropylene/polyamide-6 (PP/PA6) blend and a PP/PA6/Boron sesquioxide composite.

Design/methodology/approach
The hygroscopic behaviour of the PP/PA6 blend and PP/PA6/Boron sesquioxide composite was studied using a water contact angle goniometer in this study. To validate the hygroscopic behaviour of the blend and composite, water contact angles and surface energy of the materials were investigated. Tensile strength and hardness tests were used to determine mechanical characteristics, and tribological experiments on a pin-on-disc tribometer were used to demonstrate the friction and wear rates of dry and water-conditioned blends and composites. The melting temperature of dry and water-conditioned composites was determined using DSC analysis.

Findings
The hygroscopic effect of the PP/PA6 blend was found to be minimal in the experiment, while it was relatively dominating in the PP/PA6/Boron sesquioxide composite. Tensile strength was found to be somewhat lower in blend and composite compared to virgin PP, whereas hardness was found to be higher in both blend and composite. The composite's tribological testing findings were fairly outstanding, with the coefficient of friction (COF) and wear rates significantly reduced due to boron sesquioxide reinforcement. The reaction between boron sesquioxide and water molecules produced boric acid, which increased the tribological characteristics of the composite even further. Following 30 days of water conditioning, the weight of the blend increased by 3.64% and the weight of the composite increased by 6.45% as compared to the dry materials. After water conditioning, tensile strength reduced by 0.8% for the blend and 14.16% for the composite. Hardness was determined to be the same in the dry state and after water-conditioning for blend but dropped 1% for composite. As compared to blend, the COF and wear resistance of composite were 15.52% and 25.16% higher, respectively. After absorbing some water, the results increased to 28.57% and 34.9%, respectively.

Originality/value
The mechanical and thermal behaviour of polymer composites (particularly polyamide composites) vary depending on the surrounding environment. Tests were carried out to explore the effect of water treatment on the tribo-mechanical and thermal characteristics of PP/PA6/Boron sesquioxide composite. Water treatment caused polyamides to bind with water molecules, resulting in voids in the material. The interaction between boron sesquioxide and water molecules produced boric acid, which increased the tribological characteristics of the composite.


Studies were carried out on the degradation of cotton waste, rice straw and cocoa pod husks using Pleurotus pulmonarius in cultures incubated for 0-60 days. The proximate composition, percentages of nitrogen, carbon, potassium and phosphorus, pH, lignin contents, organic matter and enzyme production were determined using the substrates degraded by P. pulmonarius. Crude protein increased significantly throughout the incubation period from 1.27% in the control to 12.63% in cotton waste, 6.65% to 14.82% in rice straw and in cocoa pod husk from 7.04% to 13.82%. Crude fibre decreased significantly in cotton waste and cocoa husk from 5.88% to 5.31% and from 39.88% to 34.95% respectively but an increase was observed in rice straw from 18.42% in control to 28.08% after 60days of incubation period. The nutrient contents, pH values, organic matter showed significant differences of (P≤0.05) in the three substrates as the days of fermentation increased. Lignin contents of treated cotton waste and cocoa husk were degraded by Pleurotus pulmonarius but an increase was observed in the rice straw. Cellulase activities decreased significantly in contrast to the lignase activities where a consistent increase was observed on the degraded substrates as the incubation period increased.

A method was developed for quantification of six organophoshorus pesticides ( OPP ): chlorophos, dimethoate, chloropyrifos, fosalon, diazinon, and methyl parathion. The method allows the target compounds to be determined at a level of 1 ng/ml (1 ppb) in blood and urine samples by gas chromatography with tandem mass-selective detection. Sample preparation procedure includes salting and liquid-liquid extraction with acetonitrile. Method has passed methrological certification (certificate № 222.0320/01.00258/2013), and can be used for monitoring of employees engaged in the production and use of pesticides, as well as those with low levels of cholinesterase activity, or with the corresponding clinical symptoms. The detection limit makes it possible to reveal the intake of OPPs over a period of up to 6 days post exposure at doses equvalent to 1/10−1/50 LD 50 . The method was tested in a toxicological experiment on male rabbits after oral administration of mixture of six OPP's. Doses of OPP's was equivalent to 1/10 LD 50 and 1/50 LD 50 . The main toxicokinetic parameters of dimethoate, chloropyrifos, fosalon, diazinon, and methyl parathion was evaluated.


Several experimental investigations to obtain the drag performance of 10% scale-model disk-gap-band-type parachute assemblies trailing in the Viking forebody wake were conducted over the range of Mach 0.2 to 2.6. The wind-tunnel tests varied both the canopy trailing distance and ratio of suspension line length to canopy diameter. The data obtained permitted optimization of both parameters. Parachute drag performance in the forebody wake is markedly degraded transonically beginning at M « 0.6, reaching a minimum value at M = 1.0, then approaching the subsonic value for the selected configuration as Mach number is increased to 1.4. Further increase in Mach number causes the drag coefficient to again decline. A 20% increase in parachute-alo ne transonic drag coefficient was obtained by increasing suspension-line length ratio (S/D0) from 1.16 to 1.73. Increasing canopy trailing distance also significantly improved drag performance. Flight-test and wind-tunnel data are in good agreement.


A formulation for analytical study of cable roof systems is presented wherein the flexibility of supports bounding the roofs is accounted for. The analytical work is based on the finite element method and accounts for nonlinearity of the cable assembly using the Newton‐Raphson method. The supporting structure is, however, treated as being linear. Using this approach, examples of bicycle wheel type cable roofs are analyzed and the results compared with those obtained on a laboratory model as well as on a prototype. A parametric study of the laboratory model is also made.

The location of cemeteries is not a chance outcome: it is the result of funerary choices dictated by the social, political, cultural and ideological characteristics of human groups. Studying the spatial distribution of burial sites has thus the potential to provide some insights into the mortuary behaviors of ancient societies. Accordingly, this paper aims towards a better understanding of the place allocated to the dead within the wider landscape of Bronze Age Crete. A series of GIS-based thematic maps and spatial analyses (such as clustering, viewshed, site catchment, least-cost path, a.o.) are of particular interest to reconstruct the territorial and visual relations between the tombs, the rest of the archaeological remains and the natural environment. In the context of Minoan Crete, where the funerary data are plentiful but badly preserved and thus hard to interpret, such issues are especially important since that can contribute to shed light on the place, roles and functions the deceased were assigned within the living community.


CSMA/CA networks have often been analyzed using a stylized model that is fully characterized by a vector of back-off rates and a conflict graph. We present an explicit formula for the unique vector of back-off rate needed to achieve any achievable throughput vector provided that the network has a chordal conflict graph. These back-off rates are such that the back-off rate of a node only depends on its own target throughput and the target throughput of its neighbors and can be determined in a distributed manner. We also introduce a distributed chordal approximation algorithm for general conflict graphs which is shown (using numerical examples) to be more accurate than the Bethe approximation.


Objective: To investigate the relation between erythrocyte defomability, blood viscosity and insulin resistance in aged type 2 diabetics. Methods: Fourty-two patients with type 2 diabetics(23 males, 19 females, aged 68.2±7.3 years) were measured the oral glucose tolerance test, insulin releasing test, blood lipids and short time insulin tolerance test(calculate Kitt value), and examined the blood rheology items such as blood viscosity in different shear speed, cytorheology parameters DImax, AImax(deformation index, aggregation index). Results: The blood viscosity(BV) of three shear rates(10 s-1,60 s-1,160 s-1) and the reduced blood viscosity(RBV) of two shear rates(10 s-1, 60 s-1)elevated. The erythrocyte max deformation index(DImax) lowered, while the max aggregation index(AImax) increased. By multiple linear regression analysis, Kitt value was found correlated with BV(10 s-1), RBV(10 s-1) and DImax. Conclusion: High blood viscosity and impaired erythrocyte deformability in erythrocyte membrane may increase resistance to insulin in aged type 2 diabetes.

Education is one of the important factors to support one's future. Madrasas are one of the places of education that currently tend to be an option. This existence is caused by religious values which are more emphasized in madrasas. In madrasa students are expected to be independent and achieve, in accordance with the slogan of the madrasa itself. Independent is meant to be able to know, recognize himself and then be able to develop himself. While the word 'achievement,' has the meaning of an effort from independence and proud performance. However, observations at the An-Nur Foundation found that further guidance was needed to shape the character of Madrasah Ibtidaiyah students who were independent achievers. This research was conducted using the Community Based Research (CBR) method, which is a research conducted with the community in solving the problems they are experiencing. The emergence of CBR begins with the development of relationships between researchers and community organizations that jointly carry out research activities using scientific methods and community-based approaches. The results of this study are in the form of a pocketbook entitled Majmu>'a>t al-Adhka>r wa al-S}alawa>t (A Collection of Remembrance and Salawat) which is a summary of a series of madrasa activities at the An-Nur Foundation. The existence of this pocketbook is expected to be able to assist in carrying out the existing series of activities.


Technical documents for multilateral agreements or international business transactions are normally produced in a bilingual or multilingual form. Being mostly of legal nature, these documents require especially accurate and speedy translations by expert translators. In order to aid these experts, automatic ways of checking translation results (such as a spelling checker) would be highly desirable. This paper describes the MIRAC system for Multilingual Information Retrieval And Checking. It is designed to find translation errors in multilingual documents, and to evaluate the overall results of translation. Unlike a machine translation or a translation memory system [Volk98, Webb98], the primary function of the MIRAC system is to evaluate previously translated and aligned documents in source and target languages, while dynamically building a database that consists of aligned multilingual texts carrying semantically equivalent content.

A 35-yr-old Asian nonsmoking housewife was seen in the asthma clinic in September 2006 with cough and haemoptysis. Her past history included atopic brittle asthma [1] since childhood with two intensive care unit (ICU) admissions in the past requiring mechanical ventilation, the latest being 1 month previously.

She was on maximal treatment for her asthma, and had recently been admitted to the ICU in June–August 2006, initially with an exacerbation of asthma with bilateral pneumothoraces, subsequently complicated by sepsis and acute respiratory distress syndrome. She was slow to wean from the ventilator and required a mini-tracheostomy for 19 days. In the period following discharge, she had been reviewed weekly in the clinic. She complained of a dry cough and dyspepsia, which was treated with a proton pump …


A computer solution of the wave‐difference equations is found by using an interlacing implicit‐explicit scheme. In the computation, the entire two‐dimensional field is found as a function of time. The examples considered involve propagation in a homogeneous shallow‐water channel, where the effect of superposition of discrete spectra produces characteristic modal patterns. The spatial sound‐pressure fluctuations are represented as plot‐density variations along the two‐dimensional channel. Examples of discrete propagated modes as well as evanescent modes are presented. The size of the field that can be presented is limited by the size, accuracy, and speed of the computer.


Algal remains recovered from sediment traps in Rostherne Mere, Cheshire, broadly reflected the phytoplankton periodicity and suggested that the turbulent resuspension of sedimented material occurs infrequently. Quantitative comparisons between the standing crops and the algal fluxes intercepted by sediment traps indicated that the cylindrical traps yielded accurate estimates when operated in weakly turbulent waters but apparently exaggerated the fluxes when operated in turbulent conditions.


[Objective]To explore relations of P27 expression to cavcinognensis and clinicalpathological character of gastric carcinoma.[Methods] Immunohistochemistry mothed was used to detect P27 expression in 58 samples of gastric carcinomas and 33 samples of non-tumor gastric epithelia,and the associations of expression of P27 with gastric carcinogenesis as well as clinicalpathological character of gastric carcinoma was analyzed.[Results] The positive rate of P27 expression was 46.6%(27/58) in gastric carcinoma,and its significantly lower than that(81.8%,27/33) in samples of non-tumor gastric epithelia(P0.01).P27 expression was not signifi-cantly related to clinicalpathological character of gastric carcinoma.[Conclusion] The carcinogenesis may be re-lated to decreasing of P27 expression in sore gostric carcmowas.


The steel micro-alloyed with ferrovanadium nitride has extremely superior properties that make it widely utilized in structural components, construction and aircraft. The conventional methods for synthesizing ferrovanadium nitride include nitridation of pure ferrovanadium alloy or carbothermal nitridation of metallic oxides, using nitrogen or ammonia gas as nitrogen sources. In this study, ferrovanadium nitride (FeV45N) was prepared by direct reduction and nitridation of the corresponding metal oxides with ammonia as the reductant and nitrogen source. This method avoids the introduction of other impurity elements, except the negligible trace elements accompanied with the raw materials. The thermodynamics of the reduction and nitridation process were initially analyzed. During the subsequent ammonia reduction process, the FeV45N powders were successfully obtained at 1273 K for 6 h. The obtained powders were pressed into cylindrical briquettes by hot pressing (HP) at 1473 K for 1 h in vacuum. In the investigation, the X-ray diffraction and morphological analysis of the products was also carried out, and the reaction mechanisms were discussed in detail. The nitrogen content of the final product can reach 11.85 wt. %, and the residual oxygen content can be reduced to 0.25 wt. %. By sintering, the density of the alloy can reach 5.92 g/cm3.


Lepidium meyenii, known as Maca, is a Peruvian herbaceous biennial plant used by indigenous Andean societies as a source of nourishment and healing. Macamides, a distinct class of secondary metabolites which are structurally similar to the endocannabinoids, have neuroprotective effects. The purpose of this study was to evaluate the neuroprotective effects of some of the most prominent macamides: N‐(3‐methoxybenzyl) oleamide, N‐(3‐methoxybenzyl) linoleamide and N‐(3‐methoxybenzyl) linolenamide, at concentrations of 0.1 to 50uM, on U87MG glioblastoma cells exposed to a neurotoxic concentration (10 μM) of MnCl2. A cell viability assay utilizing 3‐(4, 5‐dimethylthiazol‐2‐yl)‐5‐(3‐carboxymethoxyphenyl)‐2‐(4‐sulfophenyl)‐2H‐tetrazolium (MTS) was performed to evaluate the neuroprotective effects. The results demonstrated that the macamides counteracted the toxicity of MnCl2, showing significant increases in cell viability in response to N‐(3‐methoxybenzyl) oleamide and N‐(3‐methoxybenzyl) linoleamide at all concentrations studied (21% and 25% respectively). A dose dependent increase in cell viability was observed for N‐(3‐methoxybenzyl) linolenamide (P≤ 0.001). Moreover, glutathione levels and other markers were measured to evaluate the neuroprotective effects of macamides. Further assays will be performed in order to determine the mechanism of neuroprotective activity demonstrated by these macamides.


On the basis of modern archaeological data verification, ancient people in China had known silver mineral and silvery mineral, had grasped the mining and smelting techniques about silver ore and the manufactured silverwares had achieved very high level craft techniques. Due to the reason that silvers output is very rare, and the making is very easy. Jewelry, handicraft and coins were extensively made by the ancient people in China.


1565 | P a g e  Abstract— After many Internet-scale worm incidents in recent years, it is clear that a simple self-propagating worm can quickly spread across the Internet and cause severe damage to our society. Facing this great security threat, we need to build an early detection system that can detect the presence of a worm in the Internet as quickly as possible in order to give people accurate early warning information and possible reaction time for counteractions. In this paper, we present a (stochastic) branching process model for characterizing the propagation of Internet worms. The model is developed for uniform scanning worms and then extended to preference scanning worms. Our strategy is based on limiting the number of scans to dark-address space. Our experimental results show that this proposed method is somehow better compared to other techniques.


A new sequence combining chemical‐exchange saturation‐transfer (CEST) with traditional MRS is used to simultaneously determine metabolite content and effects of magnetization exchange.


Objective To investigate the effect of music therapy plus selective serotonin reuptake inhibitors(SSRIs) on emotion and burn wound healing in burn patients. Methods Moderate and severe burn inpatients, aged 12-60 years were selected. Emotional problems were then measured by the Hamilton Rating Scale for Depression and Hamilton Rating Scale for Anxiety within three days after burn injury. Burn patients with depression and anxiety were randomly allocated into the trial group (28 patients) and the control group (27 patients). Music therapy and SSRIs plus conventional burn care were applied to the trial group, and conventional burn care to the control group, both for 30 days. The scores of anxiety, depression and the degree of burn wound healing were assessed.Results The differences of depression score and anxiety score before and after treatment were 13.7±6.43 and 6.43±2.72 respectively in the trial group, and 4.74±6.75 and 4.44±3.36 respectively in the control group. This showed both scores significantly improved compared with the control group (P0.05). The time for burn wound healing was shortened in the treatment group (P0.05).The anxiety score was positively correlated with burn index, and so was the depression score (P0.05). Conclusions The anxiety and depression scores are positively correlated with the burn index. Music therapy plus SSRIs can ameliorate the emotional problems (depression and anxiety), and shorten the time for burn wound healing.


Dictyophyllum indicum n. sp. and Hausmannia pachyderma Sukh-Dev, described here, were collected from clay pits near Than in Saurashtra. Both the species are based on sterile fronds. The overall shape of the sterile segments of D. indicum is more like the fertile segments of D. rugosum Lindley & Hutton.


The number of applications of stimulus-responsive polymers is growing at an impressive rate. The motivation of this contribution is to use a commercially available low-budget silver-coated polyamide (PA6) as a thermo-responsive metal-polymer hybrid soft actuator. Polyamide is a hygroscopic polymer; therefore, its mechanical and physical-chemical properties are affected by exposition to humidity or immersion in water. The effect of water absorption content on the PA6 and silver-coated PA6 monofilament properties, such as mass change and resistance, were evaluated. Moreover, the influence of swelling and shrinking effects on the surface morphology, caused by variations of moisture and water immersion, was investigated. Based on these variations, the dynamics of the resistance of the hybrid material were analyzed in the context of the proposed hysteresis model. An identification procedure of the hysteresis is presented along with an approximation of the upper and lower bound based on a constrained least square approach. A switching logic algorithm for this hybrid dynamic system is introduced, which makes it possible to structure the non-linear function in a switching mode. Finally, a non-linear integral sliding manifold is proposed and tested to control the resulting force of the actuator.hysteresis model.

Regional Advisory Committee in ENT should have an audiology subcommittee that is well supported, disseminates expertise within its region and provides evidence on requirements for audiological staff. It is also important to develop a little audiological knowledge in the community bases of referrals for audiological services. The chief professional groups involved are general practitioners, clinical medical officers, health visitors, social workers and screening audiometricians. This liaison can be delegated to an audiological scientist. General practitioners could consider purchasing a simple screening audiometer with Audio cup sound-isolating headphones (£350 approximately), becoming briefed in its application and having a nurse trained in its use according to the methods approved by the British Society of Audiology and the British Association of Otorhinolaryngologists. (It is important that this should not presume to dilute or preempt definitive audiological assessment in hospital outpatient clinics. It is suggested purely as a more objective and selective basis for encouraging more of the middle-aged and elderly to seek specialized assistance (cf. Humphrey et al. 198\). Use in other applications, e.g. otitis media, should only be attempted within a programme overseen by a specialist.) GPs should also keep up-to-date information on the gamut of audiological services available locally, and be aware of the greater efficacy, cosmetic acceptability and wider application of the modern hearing aid in comparison with that of 10 years ago. Researchers could question the widespread assumption that what is needed are ever more precise and costly measures to aid 'diagnosis', and orient more research towards providing more effective rehabilitative management together with engineering solutions that are robust and practicable to deliver. As funds become available they could also undertake more research on operational factors, the effectiveness and economics of elements of a comprehensive audiological service, for example, arranging trials of pre-retirement screening programmes for 60-65 year olds together with encouraging experimental trials of aids 'before they are essential'. This is justified on epidemiological grounds and could provide valuable information on how to cope with the challenge of the next 20 years. While little of the above could be regarded as controversial, equally little of it could be described as accepted. If action in the. spirit of these recommendations were taken now, there would exist a framework for applying the more detailed results of research now under way.


Cyclic olefin copolymers are important in polymer material due to their high transparency, good thermal stability, mechanical strength and easy to make film. The hydrophobic cyclic olefin copolymers were not compatible with hydrophilic material and have less chemical attraction each other. Therefore scientists develop many polymerization technology,which contain the grafting polymerization, blocking polymerization, and direct copolymerization with polar monomer, Most of them are grafting polymerization or blocking polymerization, since they contain the function of group and also maintain polymer orginal properties. We expect to improve polymer applications and bring on the material apply to the different domain. This experiments are carried by using the unsaturated alkene alkyl radical on poly[E-co-ENB-co-norbornene] and the hydrogen chloride watery solution. After the reaction the Cyclic olefin copolymers contain Cl group, The grafting of PMMA and PBA are used by atomic transfer radical polymerization methol. The reactions in different temperature, the catalyst system, and the solvent are discussed. At the same time, the products are identified by 1H-NMR, FT-IR, DSC. Theproperties of Cyclic olefin copolymers are studied by using of GPC, UV-VIS, and Contact Angle .


The efficiency of tail recursion and the simplicity of its removal makes some people wonder why we cannot transform all recursive definitions to this form? Clearly, the usual trick of introducing a new variable and using it as an accumulator to hold the intermediate results during the winding phase does not always work. But, by trying to generalize this technique to primitive recursion one can easily find a sufficient condition which makes it work. The class of functions satisfying this condition may be interesting also on its own. A direct generalization of this function class for mutual recursion is fairly straightforward.


The sexual dimorphism of human central nervous system (CNS) is a fact confirmed in many imaging and functional studies. The action of sex hormones in fetal and postnatal life seems to be main factor determining the brains' gender. Recent studies revealed that estrogens are potent modulators of CNS function also in adults and they pose many non-reproductive activities. It was also proven that estrogens could be synthesized in brain and act directly in there. The action occurs not only through slow acting genomic effects, dependent on nuclear receptors, but also by rapid non-genomic pathway. Many brain structures were found to be estrogen-sensitive and they can be recognized as specific neural systems disseminated in whole CNS. It was found that the cholinergic, serotoninergic and dopaminergic systems are under strong influence of estrogens. In general, animal and human studies indicates that estrogens have a stimulatory and neuroprotective functions in these systems. It brings opportunity that these sex steroids can be of significance for pathology and treatment of neurodegenerative diseases, psychiatric traits and substance addiction.


Event relation knowledge is important for deep language understanding and inference. Previous work has established automatic acquisition methods of event relations that focus on common sense knowledge acquisition from large-scale unlabeled corpus. However, in the case of domain-specific knowledge acquisition, such a method can not acquire much knowledge due to the limited amount of available knowledge sources. We propose an coverage-oriented acquisition method of event relations. The proposed method utilizes various patterns of dependency structures co-occurring with event relations than the existing method relying only on direct dependency relations between events. Experimental results show that the proposed method can acquire a larger amount of positive relation instances while keeping higher precision compared with the existing method and the proposed method also performs well for small sizes of corpora.


One of the most familiar phrases of medieval philosophy is the definition of eternity given by Boethius: "the complete possession all at once of unlimited life." 1 As is well known, this definition would seem to derive from that of Plotinus, who defines eternity (αἰών) as "the life which belongs to that which exists and is in being, all together and full, completely without extension or interval." 2 The Plotinian definition, in turn, was a distillation of a longstanding consensus among the Platonists of antiquity, one that neatly synthesized the conception of eternity in the Timaeus with that of Aristotle in Metaphysics Λ and the De Caelo. (I shall return to this subject below.) Seen in that light, the Boethian definition is the fruit of a rich and deeply rooted tradition. What is surprising in Boethius' discussion of eternity is not the definition itself, but the way in which it is applied to God. Boethius prefaces it by the statement: "Now that God is eternal is the common judgement of all who live by reason. Therefore let us consider, what is eternity; for this makes plain to us both the divine nature and the divine knowledge." 3 For Boethius, eternity is a feature of the divine nature; indeed, one could even say that eternity is the divine nature. As he explains in his theological tractates, in God there is no distinction between substance and attribute, so that for God to be just, good, or great, and simply to be God, are one and the same. 4 Although in these discussions Boethius does not mention eternity, there can be little doubt that, in his view, for God to be eternal and to be God are also one and the same. The place of eternity in the Plotinian system is sharply different. For Plotinus eternity is a characteristic of the second hypostasis, Intellect, and as such is wholly derivative from the One. As he goes on to explain in the treatise containing his definition, the nature that is eternal "is around the One and comes from it and is directed towards it," so that eternity is "an activity of life directed to the One and in the One." 5 Since eternity arises only at the level of the second hypostasis, in the process of emanation from the One, the One itself is no more eternal than it is temporal. As Plotinus states elsewhere, the One "was what it was even before eternity existed." 6


Analysis and prediction of Chinese town employment risk based on order logit model show that the probability of unemployment rate in town to be above 6.454% is almost to be 100% in 2009 and 2010 by contrast to Asia Financial Crisis in 1997.The countermeasures to promoting employment in the future including: development of informal employment and medium and small sized private-run enterprises,adjustment of industry structure and cross-regional industry transfer,employment of expansionary fiscal and monetary policies for more jobs,improvement of labor market and quality of labor force as well.


Acquiring process knowledge and skills and transferring technology into and across the organization creates a distinctive competitive advantage. A world-class methodology that accelerates improvement is presented. This methodology is proven effective in manufacturing and service industries, various government agencies and educational institutions. The process of planning and accelerating improvement using an integrated, self-evident set of principles distinguishes between mediocrity and excellence. This approach through systematic application results in more depth and breadth of process learning and facilitates greater acceptance of new thinking and using the latest technology. Our findings through this approach demonstrate that a pathway to continuous improvement can be achieved; thus, unbounded performance levels exist. Since improvement is always a people business, the model also enables each person to attain a greater sense of accomplishment, to acquire skills and knowledge that serve our lives and achieve our goals with a greater sense of confidence and hope.


Summary . Nonlinear normal modes (NNMs) are obtained and analysed in the dynamics of some elastic structures. Namely, nonlinear vibro-absorption problems, nonlinear shell dynamics, snap-through motions of shallow arches and the nonlinear dynamics of vehicle suspensions, are considered. Analytical and numerical results show a good agreement.


The utility model discloses a modified sheet manufacturing device, which comprises a feeding mechanism, a mixing mechanism, an extrusion mechanism, a cooling forming mechanism, a surface treatment mechanism, a drawing printing mechanism, a surface protection mechanism, a winding mechanism and temperature controllers which are sequentially arranged. The surface treatment mechanism is formed by an upper roller, an intermediate roller and a lower roller, the three rollers are installed on a same roller support, the upper roller and the intermediate roller form a group, and the intermediate roller and the lower roller form a group. The temperature controllers are respectively disposed between the upper roller and the intermediate roller and between the intermediate roller and the lower roller. By adding one roller on an original two-roller base on the surface treatment mechanism, a structure where the upper roller, the intermediate roller and the lower roller are in mutually engaged movement is formed, and sheets are processed twice via the rollers, thereby achieving not only excellent thicknessing effect, but also fine surface effect, having rather ideal effect of smoothness, relief, texture and the like of manufactured products, and improving product quality.


INTRODUCTION
The direct endonasal, paraseptal approach, performed with the aid of an operating microscope, for removal of pituitary and peripituitary tumors has the potential advantage over the traditional sublabial, transseptal routes of minimizing postoperative rhinological complications, yet maintaining a high degree of efficacy and safety. Combination of this approach with the endoscope or neuronavigation may improve the effectiveness of the operation.

METHODS AND RESULTS
Between June, 2000 and June, 2003 two hundred and seventeen patients underwent 221 paraseptal operations for tumor removal at the National Institute of Neurosurgery, Budapest. To asses the effectiveness of this procedure, duration of the operation, tumor remission rates and surgical complications as well as postoperative complaints of patients were reviewed. Surgical remission rates for pituitary adenomas were as follows: 94% for microadenomas, 67% for macroadenomas and 29% for giant adenomas. There were five surgical complications and no operative deaths. Ten out of 12 patients, who had undergone transseptal surgery previously, preferred the endonasal approach in terms of pain and ease of recovery.

CONCLUSIONS
The direct paraseptal route for pituitary and pericellar tumor removal has an efficacy and complication rates comparable to those of the transseptal and sublabial routes. Patients generally recovered rapidly from this minimally invasive procedure and had no or minimal sinonasal complaints. For patients requiring a repeated operation, the paraseptal route appears to be less painful and easier to recover from, than the transseptal route.


Let {X(t);t≥0}be a Gaussian process with stationary increments,X(0)=0(a.s.), EX(t)=0 and σ~2(h)=EX(t+h)-X(t)~=EZ~2(h)=Coh~(2α),0α≤1. In this paper,we first prove that the Levy's theorem of the modulus of continuity of the Wiener process is also true for {X(t);t≥0};i.e. Furthermore,we point out that some results on increments of the Wiener processes in[3]and[4]remain true for the increments of {X(t);t≥0}.


The first-order properties of acoustic waves (i.e., the to and fro particle displacement and velocity) can produce a number of second-order phenomena: cavitation, acoustic streaming, surface instability and radiation pressure. The dependence of cavitation induced phenomena (erosion, luminescense, chemical reactions) on the physical and acoustical parameters of a system are discussed. Some of the past work carried out in this field is analyzed and reinterpreted. In the light of this, it appears that the extent of the solubility of a gas has a pronounced effect on cavitation related phenomena in addition to the effect of other variables such as the ambient liquid temperature, the hydrostatic pressure, the specific heat ratio, the thermal conductivity of dissolved gas and the intensity and frequency of acoustic field. A summary of the application of sonic and ultrasonic energy to industrial processing operations is also provided. This discussion includes how the other second-order effects (e.g., interfacial instability) are related to the enhancement of these operations. The wide variety of processes in which the applications of acoustic energy has a beneficial effect suggests the versatility and broad commercial potential of sonochemical engineering.

Pediatric Dentistry 19:2, 1997 Organizations representing groups of health care professionals initially responded to this call for accountability by developing policy statements that reflect consensus about the "state of the art", or level of development of practices for dealing with specific conditions at a particular point in time, in their respective clinical disciplines. Examples in the field of pediatric dentistry include the Oral Health Policies,


Ambient temperature hydrostatic pressurization tests were conducted on a composite overwrapped pressure vessel (COPV) to understand the fiber stresses in COPV components. Two three-dimensional digital image correlation systems with high speed cameras were used in the evaluation to provide full field displacement and strain data for each pressurization test. A few of the key findings will be discussed including how the principal strains provided better insight into system behavior than traditional gauges, a high localized strain that was measured where gages were not present and the challenges of measuring curved surfaces with the use of a 1.25 in. thick layered polycarbonate panel that protected the cameras.


The design of high-speed recording heads requires one to consider the effect of eddy currents on performance. Experiments have shown that even for very thin laminations, there is an appreciable eddy current effect for high recording frequencies. A technique is suggested for including these effects in a micromagnetic calculation. This technique has been implemented in a finite difference calculation and some results are presented. The structure of the computational algorithm is considerably different from conventional eddy current calculations.


A planar optical modulator operating near 360 nm suitable for ultraviolet spatial light modulation has been constructed. The modulator operates in transmission mode with a 18% change in transmission at 305 V. The modulator is based on using the electric field to shift and broaden the room-temperature resonance of the gallium nitride exciton with electric fields.


Magnetic nanomaterials are particularly useful for extracting and enriching a large volume of target analytes because they provide high surface-to-volume ratio, easy surface modification, and strong magnetism. This review summarizes the recent advance in synthesis, modification, and application of magnetic nanomaterials for the preconcentration of environmental pollutants. The extraction of environmental pollutants with magnetic nanomaterials is generally based on hydrophobic interaction, electrostatic attraction, and/or covalent bonding formation. Environmental pollutants adsorbed on the surface of nanomaterials are released by exchanging ligands, adjusting pH, or adding organic solvent. The liberated environmental pollutants are commonly detected by gas chromatography, high-performance liquid chromatography, and inductively coupled plasma-optical emission spectrometry. The basic principle of each nanomaterial and its advantages for the extraction of environmental pollutants are discussed in this review.


The purpose of this study was to design, test, and implement a quantitative student model called the Angel Model to measure programming abilities of undergraduate students who have taken the first Computer Science course. The Angel Model is a testlet design in which questions are grouped into related units.
The major problem to be explored in this research was how well does the Angel Model compare with the traditional testing approach and the Partial Credit Model using a preliminary course score as the criterion? This research also explored the possibility of implementing an IRT (Item Response Theory) based Computerized Adaptive Testing (CAT) system utilizing the quantitative student model (Angel Model). Based on the results of factor analyses, it was concluded that the testlet design met the unidimensionality assumption and therefore can be used for developing an IRT based CAT system. The results of correlational analyses showed that the Angel Model had a slightly higher correlation coefficient than did the classical test approach and the Partial Credit Model using a preliminary course grade as the criterion.
In conclusion, this research demonstrated that a quantitative student model is a feasible model which can be developed to measure student programming ability. The results of this research study showed that the format and the content of the testlet design in the Angel Model are valid for measuring students' programming abilities and can be used for developing an IRT based CAT system. A testlet design which groups questions into related units is a better method for testing students' programming abilities. The Angel Model, which is a method to quantify students' misconceptions in computer programming, can be used to improve teaching. Another conclusion of this study is that when students' understanding of a domain (e.g., Chemistry and Physics) can be built quantitatively, a CAT can then be developed effectively to measure students' abilities in that domain. Hence, the quantitative student model can provide an Intelligent Tutoring System with knowledge about students' abilities in that domain. The Angel Model may be generalized to all ITSs.


Wireless sensor network (WSN) such as vehicular ad hoc network (VANET) usually has a bunch of nodes on the move, thus, connectivity and network coverage for WSN has now been recognized as a thorny issue which should take the range of area, the number of nodes into consideration. A better WSN coverage scheme can not only optimize network resources, but improve the efficiency of the network as well. Till now, many scholars have studied the very coverage scheme by means of node deployment or connectivity analysis, while others have studied the coverage hole repairing scheme in case of any end nodes fails; coverage studies for WSN in specified scenario like VANET with vehicle nodes moving in a certain range of area are still hard to be found. In this paper, based on the analysis of the specified requirements in VANET, a coverage approach for such kind of WSN has been proposed with algorithm in detail, and by setting 2 cases as examples, the effectiveness of such approach has been verified. The coverage algorithm proposed may not be the optimal coverage scheme, but it can be applied in specified scenario with moving nodes and be supposed to get coverage result timely for its simple arithmetic logic efficiently.


" IN your opinion, would this man have died at the instant he did die, had he never been employed as a coal miner?" This is the type of question which frequently confronts medical men in the county courts. Logically, only one condition is essential for death-namely, the phenomenon oflife. Strictly speaking, any factor which diminishes by one instant the greatest possible degree of longevity" accelerates" death. Obviously, all the factors concerned in promoting the greatest possible length of life are not known, and only a loose opinion, wide in range, covers the matter. If every environmental detail could be selected with the object of prolonging life to the greatest possible degree, not only would there exist a wide divergence in the choice made by different " selectors," but many necessary occupations would, no doubt, be avoided. Indeed, does not every modern mode of life present some aspect which might reasonably be held to reduce a person's lifetime below its maximum possible duration? Yet on that ground the avoidance of any such employment, or phase of life required by employment, carries the inference that life would be shortened and death accelerated thereby, and the question may be asked, " Was it the intention of the Workmen's Compensation Act to endow all workers to whom this argument may be applied with life assurance against death from old age ?" Many may feel that this was notthe intention of the Act; that a much closer and more direct connection between employment and death or disability should be established in order to substantiate a claim. But here it becomes impossible to draw a hard line of distinction, for the time factor intervenes. Post hoc, propter hoc evidence may be strong where the time interval is short-as when a sane man is entombed and on liberation is seen to be a gibbering maniac-but where a period of time elapses between a supposed cause and effect, the strength of the evidence is in inverse ratio to the lapse of time.


Nonlinear dynamic model has been suggested for assessing and predicting the number of social network users. It was shown that Maurer and Huberman's model describes the dynamics of users quite well in the short term. But the appearance of new services and changes in network strategy shift the parameters of system, which significantly affects to users' dynamics in the long-term. So the objective of the study was the modeling of the number of social network users in the long-term. The results have shown that the introduction of variable coefficients allows to describe the dynamics of real data more qualitative – the system can have several stable states of equilibrium; dynamics depends on the competitors' strategies; the final state of the system is sensitive to initial conditions.


Abstract Some alkaloid standards and synthetic or natural alkaloid mixtures were chromatographed on phenyl‐silica stationary phases using various aqueous eluents: aqueous methanol or acetonitrile mixture, buffered aqueous mobile phases at pH 3 to suppress silanols' ionisation, or at pH 8 to suppress alkaloids' ionisation. Strong silanophilic interactions that can occur with these analytes and the adsorbent surface can lead to poor peak shape and resolution. Mobile phases with anionic ion‐pairs such as sodium dodecyl sulphate, octanesulfonic acid sodium salt, or HDEHP were used to improve efficiency, peak shape, and selectivity. The effect of silanol blockers – different amines on the retention, efficiency, and peak shape for RP systems, was analysed.


This text was spontaneously narrated by a Purepecha woman, now a resident of Mexico City, but originally from Puacuaro in the lake area. The protagonist relates part of her story as a migrant to the city and also tells of the difficulties she has encountered in urban daily life. In the first part she describes her present life as a cook in a small restaurant. In the second, she tells of her early marriage, then her temporary break with her husband and first arrival in Mexico City where her first child was born. In the years following she returned with her husband and bore four more children. Of special interest also are the ways in which she has maintained contact with her community, spending several periods of time there during the past twenty years or so, in part due to her sometimes unstable marital relationship. At the end of her account, she speaks of her children and the ways in which they have helped her, while she has struggled to maintain them. Alejandra Capistran provides a detailed linguistic analysis of the text in the interlineal translation, with footnotes that explain specific points of the grammar in more detail.


Background: Given the poorer prognosis of Alzheimer's disease (AD) patients with rapid cognitive decline (RCD), there is a need for a clinical assessment tool to detect these patients. Objective: To investigate if there is a Mini Mental State Examination (MMSE) threshold of decline during 6 months of follow-up which predicts a worse disease progression at the 2-year follow-up. Then, to propose a feasible definition of RCD for routine clinical practice. Methods: Data from 565 community-dwelling AD patients recruited in a multi-centre prospective observational study were assessed. All patients had MMSE scores between 10 and 26 at inclusion and were followed up 6-monthly using a standardised clinical assessment. Patients were classified as rapid and non-rapid decliners according to 2 MMSE decline thresholds tested: ≧3 points and ≧4 points for decline over the first 6 months of the study. Worse disease outcome was defined as attainment of 1 of 4 clinical end points 18 months later: institutionalisation, death, increased physical dependence or worsening of behavioural and psychological symptoms. Results: 135 patients (23.9%) lost ≧3 points during the first 6 months of follow-up in the MMSE score and 77 patients (13.6%) lost ≧4 points. Patients with moderate disease and a loss of ≧4 points showed a significantly increased risk of mortality (HR = 5.6, 95% CI 2.0–15.9) and institutionalisation (HR = 3.8, 95% CI 1.8–8.1) at the 2-year follow-up. The same MMSE threshold was associated with a higher risk of physical decline (HR = 1.6, 95% CI 1.2–2.3). Conclusion: The loss of ≧4 points in MMSE during the first 6 months of follow-up seems to be a predictor of worse clinical course, and thus it could be used to define the category of AD patients presenting a RCD.


Polyhaloalkanes such as carbon tetrachloride (CTC) are classified as biorefractory, highly toxic and ozone depleting materials. Those materials are suspected as being carcinogenic and are widespread contaminants in soil and ground water. Accordingly, schemes to effectively destruct and mineralize polyhalomethanes are in great need. We herewith report a novel reagent composed of sodium hydroxide, hydrogen peroxide and a phase transfer catalyst that swiftly and quantitatively mineralize bulk CTC under ambient conditions. We advocate that the key intermediate in the process is the powerful nucleophile, superoxide anion that is extracted by the phase transfer catalyst into the organic (CTC) phase. This nucleophile rapidly reacts with CTC and completely mineralizes it to sodium carbonate and sodium chloride.


The protein transient receptor potential melastatin type 8 (TRPM8), a non-selective, calcium (Ca2+)-permeable ion channel is implicated in several pathological conditions, including neuropathic pain states. In our previous research endeavors, we have identified β-lactam derivatives with high hydrophobic character that exhibit potent and selective TRPM8 antagonist activity. This work describes the synthesis of novel derivatives featuring C-terminal amides and diversely substituted N′-terminal monobenzyl groups in an attempt to increase the total polar surface area (TPSA) in this family of compounds. The primary goal was to assess the influence of these substituents on the inhibition of menthol-induced cellular Ca2+ entry, thereby establishing critical structure–activity relationships. While the substitution of the tert-butyl ester by isobutyl amide moieties improved the antagonist activity, none of the N′-monobencyl derivatives, regardless of the substituent on the phenyl ring, achieved the activity of the model dibenzyl compound. The antagonist potency of the most effective compounds was subsequently verified using Patch-Clamp electrophysiology experiments. Furthermore, we evaluated the selectivity of one of these compounds against other members of the transient receptor potential (TRP) ion channel family and some receptors connected to peripheral pain pathways. This compound demonstrated specificity for TRPM8 channels. To better comprehend the potential mode of interaction, we conducted docking experiments to uncover plausible binding sites on the functionally active tetrameric protein. While the four main populated poses are located by the pore zone, a similar location to that described for the N-(3-aminopropyl)-2-[(3-methylphenyl)methoxy]-N-(2-thienylmethyl)-benzamide (AMTB) antagonist cannot be discarded. Finally, in vivo experiments, involving a couple of selected compounds, revealed significant antinociceptive activity within a mice model of cold allodynia induced by oxaliplatin (OXA).


In an attempt to take effective action towards mitigating pollution episodes in the Greater Athens Area (GAA), precise knowledge of PM2.5 composition and their sources is a prerequisite. Thus, a two year chemical composition data set 10 from aerosol samples collected in an urban-background site of central Athens, from December 2013 till March 2016, has been obtained and Positive Matrix Factorization (PMF) was applied in order to identify and apportion fine aerosols to their sources. A total of 850 aerosol samples, were collected on a 12 to 24h basis and analyzed for major ions, trace elements, organic and elemental carbon, allowing us to further assess the impact of residential heating as a source of air pollution over the GAA. 15 The ionic and carbonaceous components were found to constitute the major fraction of the PM2.5 aerosol mass. The annual contribution of the Ion Mass (IM), Particulate Organic Mass (POM), dust, Elemental Carbon (EC) and Sea Salt (SS) were calculated at 31%, 34%, 18%, 8% and 3%, respectively. However, carbonaceous aerosols (POM + EC) and IM exhibited considerable seasonal variation. In winter, IM was estimated down to 23%, with POM + EC being the dominant component accounting for 48% of the PM2.5 mass, while in summer IM was the dominant component (42%), followed by carbonaceous 20 aerosols 37%. Results from samples collected on a 12h basis (day and night) during the 3 intensive winter campaigns indicated the impact of heating on the levels of a series of compounds. Indeed PM2.5, EC, POM, NO3, C2O4, nssK and selected trace metals including Cd and Pb were increased by almost a factor of 4 during night compared to day, highlighting the importance of heating on air quality of the GAA. Furthermore, in order to better characterize winter-time aerosol sources in the city centre 25 of Athens and quantify the input of biomass burning as a source to winter night-time PM2.5 concentrations, source apportionment was performed. Τhe data can be interpreted on the basis of six sources namely biomass burning (32%), vehicular emissions (19%), heavy oil combustion (7%), regional secondary (20%), marine aerosol (9%) and dust particles (8%). With specific emphasis on night to day contrasts their contributions shifted from 19, 19, 8, 30, 11 and 9% of the PM2.5 mass during day to 39, 19, 6, 14, 7 and 6% during night, underlining the significance of biomass burning as the main 30 contributor to fine particle levels during night-time.

The communication industry has changed completely with the arrival of the internet. Online communication is in demand nowadays becoming a necessity in people's daily activities and lives at their homes, work places, and schools. These are the markets that make online communication an essential tool to the community. As a result of the lockdown; due to the sanitary emergency that has caused COVID-19, the internet connection has shown irregularities. In this article; with the help of quality control tools such as the XS control chart, we were able to establish the exact times where the connection was most fluctuated. In addition, using the Ishikawa diagrams we found the potential causes that were creating these irregularities. Also, using a Pareto diagram led us to find the different shortcomings of the company providing the internet connection services. Based on the quality control tools implemented in this research, recommendations have been made for the improvement of this process; such as having a better planning that includes employee training, maintenance plans of the equipment, and verification of the capacity and quality of those equipment.


Abstract: Two cases of relapsing polychondritis are presented to emphasize the variety of clinical features and the seriousness of problems encountered with involvement of the cartilaginous portion of the respiratory tree. Inflammation of cartilage characterizes the syndrome, while it also affects such structures as the inner ear, sclera, and anterior uveal tract, which are devoid of cartilage. The cause of the disease remains obscure. Evidence is reviewed to suggest that the cause is either an acquired metabolic derangement or, more likely, an immune disorder with the production of autoantibodies to a substance common to cartilage and other involved organs, possibly the acid mucopolysaccharides. During acute exacerbations, these mucopolysaccharides are recoverable in the urine. Early diagnosis and treatment with corticosteroids are important.


The knowledge of three-dimensional data is essential for many control and navigation applications. Especially in the industrial and automotive environment a fast and reliable acquisition of 3D data has become a main requirement for future developments. Moreover low cost 3D imaging has the potential to open a wide field of additional applications and solutions in markets like consumer electronics, multimedia, digital photography, robotics and medical technologies. This article describes the modular design of a new generation of time-of-flight cameras, the so called PMD cameras. The key component is an array or line sensor which can measure the distance to the target pixelwise in parallel without scanning. Therefore these cameras have the advantages of fast imaging and high lateral resolution combined with the depth information of the captured scene. The sensors consist of smart pixels, called the Photonic Mixer Device (PMD) which enables fast optical sensing and demodulation of incoherent light signals in one component. Each PMD-camera consists of a sensor chip in standard CMOS technology, a modulated optical transmitter, control and processing electronics and software package. Dependent on special demands of the different application and markets mentioned above each PMD camera component has to be adapted to these demands. The paper give some examples for costumer specific solutions and the possibilities of a flexible modular camera design.

We have analysed the XMM-Newton X-ray spectra of the yellow giant 31 Com with the aim of deriving information on the coronal structures of this archetypical Hertzsprung-gap star. To determine the emission measure distribution vs. temper- ature, EM(T ), and the elemental abundances of the coronal plasma, with an accurate line-based approach, we have developed a new method for simple and accurate line measurements, based on rebinning and co-adding the two RGS spectra. We have reconstructed the EM(T ) independently with both APED and CHIANTI atomic databases in order to investigate possible differ- ences in the final outcome of the analysis, and we have obtained consistent results. The derived emission measure distribution has a well defined peak at T ∼ 10 7 K and a significant amount of plasma at higher temperatures; there is also evidence for plasma at temperatures below ∼10 6.5 K, with a mean electron density of ∼3 × 10 10 cm −3 , as inferred from the line ratio of the O  triplet. We have made a global fitting of the EPIC spectra, using multi-component isothermal (3-T) model, and then com- pared the results with the EM(T ), looking for a consistent multi-temperature description of both the RGS and EPIC spectra, over the whole spectral range. While the EM(T ) and the 3-T models individually provide a good description of the data set on which they are based, none of them describes adequately the data of all the other instruments; the disagreements may be related, at least in part, to cross-calibration problems. Finally, we have used the EM(T ) to derive information about the properties of the coronal structures. Our results indicate that the corona of 31 Com is dominated by a class of magnetic loops with peak temperature ∼10 7 K and apparently more isothermal than the solar ones.

Batter aeration as affected by substitution of el�idinized lipid and related to other properties was investigated. Elaidinized lipid was. substituted for hydrogenated safflower oil·shortening at four levels, O, 40, 60, and 80 percen�,in the preparation of lipid samples. Lipid samples were characterized by gas-liqu�d and thin-layer chromatography i and by·melting point determination. Specific gravity apd viscosity of the batters, volume index of the cakes, an4 lightrtess index of the .crumb were determined. Batter structure was studied microscopically. An increase in trans isomer concentration from 8.8 percent to 40. 6 percent was accompanied by an increase in melting poi,nt from 41.0 to 47.1 C·with increasing level of substitution. Batters from the unsubstituted shortening were most highly aerated, as indicated by·spec ific gravity, and had the greatest dispersity of.air and lipid, as indi cated by microscopic sections. The decreased extent of ·emulsi�ication. was associated with decreased batter viscosity, as well as the decreased aeration. Volume index of cakes in part reflected differences in aera tion. Decreased lightness index of cake crumb with increasing level of s�stitution resulted from the decreased light-reflecting surface and relatively poor aeration. Batter structure was not affected.bene ficially by substitution of elaidinized lipid for hydrogenated shorten ing under the conditions of this study.


This paper focus on the potential impacts of differ ent strategies used to model floods on the hazard maps subsequently produced. We consider different strategies to model the flood phenomenon, in function of: (1) the type of hydraul ic model used ‐ 1D, 1D/2D or 2D software; and (2) the choices made by the modeller when representing the topography and bathymetry of the river-floodplain system. Several modelling scenarios have been built to simulate the 100 years return-period flood in the t own of Fislis, in eastern France. We built these scenarios considering different scales of ana lysis, which implies changes in the number and position of cross-sections and hydraulic struct ures, when considering 1D models, and the digital elevation models cell resolution, when usin g 2D models. We compare the different hazard maps produced in terms of flood surface, ext ent and water depth distribution. The spatial variability of the flood maps highlight tha t special attention should be given on both, the choice of the models and the modeller choices. The comparison of maps produced for different scale of analysis revealed that this choi ce can also strongly influence their precision.

A statistical marketing consulting project financed by RAI, the public Italian television, is illustrated. Two alternative models have first been used, a statistical regression model and a data mining one, of a more empirical nature. Then the two models are hybridised in a third model, a compromise useful for applications. Finally, some real forecasting examples are illustrated.


For coechelon spaces koo (v) of infinite order it is proved that every compact subset of koo (v) is contained in a closed absolutely convex hull of some null sequence if and only if the matrix v is regularly decreasing. In connection with the study of some interesting problems on Montel maps which are closely connected to the classical Grothendieck question on completeness of regular LB-spaces [PB, Problem 13.8.6] and the problem of bornologicity of C (K, E) with E an LB-space [S, Chapter IV], Dierolf and Doman'ski [DD2, Example 3.1] gave an example of a coechelon LB-Montel space of infinite order which has compact sets not contained in closed absolutely convex hulls of any null sequence. Consequently, the well-known characterization of compact sets in Frechet spaces [J, Theorem 9.4.2] turns out to be not generally true in the LB setting. The purpose of this note is to show that for coechelon spaces k, (v) of order oc the condition v regularly decreasing [BMS, Definition 3.1] is necessary and sufficient for every compact set to be contained in a closed absolutely convex hull of some null sequence. For more information on Montel maps and related questions the reader is referred to [DD1], [DD2], [DD3] and [D]. In what follows we recall some notation. Let E be a Frechet space with a fundamental system of seminorms (I1 1In)n; then the inductive dual E' is defined to be indn E', where the En are the completions of the normed spaces (E/ ker II Kln v 11In)* It is known that algebraically E' = E', the inclusion map E4' Eis continuous and E' is the bornological space associated with E , i.e., 4E = (E', 3 (E', E")) [J, Theorem 13.4.2] (E' and EJ denote the topological dual and the strong dual of E, resp.). We also recall that an LB-space E = indnEn is called boundedly retractive (respectively, compactly regular) if, and only if, for each bounded (respectively, compact) subset B of E there is n E N such that B C En and En and E induce the same topology on B (see [PB, Definitions 8.5.32-(ii), -(iii)]). It is clear that a boundedly refractive LB-space is compactly regular. On the other hand, in [N] it is proved that these conditions are also equivalent.

Considering the complexity of solution for the problem of electromagnetic shielding by using precise boundary conditions, in order to simplify analysis and calculation of the problem on the basis of averaged boundary conditions, a new method of solution for the problem was presented on a moving large conducting plate. Compared with the solution obtained by using precise boundary conditions, the method is very simple and convenient, and in the applied limits of averaged boundary conditions, the distribution of electromagnetic fields in the free space outside the plate can be calculated with satisfactory accuracy.
