Abstract One way to improve the efficiency of automatic transfer lines is to provide intermediate storage buffers. These buffers divide the transfer line into stages, each with one or more machines. The machines in a stage are completely integrated, whereas, the stages are partially decoupled. Here, we study a problem related to buffer storage allocation. The objective is to find optimal distribution of a total storage space among the intermediate buffers. This is formulated as a dynamic programming problem and a heuristic solution is presented.


This paper proposes an approach and proof of concept for evaluating the condition of high-voltage insulators of power distribution networks (up to 145 kV) using ultrasonic tests provided by a probe equipment in a methodology based on an ensemble of convolutional neural networks and robust pre-processing techniques. It presents the laboratory tests and the conditions in which several real situations were simulated. Next, pre-processing, the neural network architectures and the flowchart of the insulation condition analysis methodology are detailed. Finally, the results of the diagnostics from the methodology with the training, validation and test sets are presented and discussed. The proposed methodology achieved 100% accuracy in validation and test data.


Recent architectural advancements in reconfigurable devices have exposed the ability to support massive parallelism inside of small, low-cost, embedded devices. The massive parallelism inside of these reconfigurable devices has promised to bring an unprecedented level of performance to the embedded systems domain. However, the complexity of programming these reconfigurable devices is daunting - too daunting for the average programmer. This paper presents Hthreads. Hthreads is a computational architecture which aims to bridge the gap between regular programmers and powerful but complex reconfigurable devices. Hthreads accomplishes this goal using three layers of abstraction built upon standard reconfigurable devices: an operating system capable of supporting a diverse collection of computational models within a reconfigurable device, an intermediate form representation which eases the development of applications on reconfigurable devices, and support for high level languages which are familiar to most programmers


Our research explores the use of mobile video chat in public spaces by people participating in parallel experiences, where both a local and remote person are doing the same activity together at the same time. We prototyped a wearable video chat experience and had pairs of friends and family members participate in 'shared geocaching' over distance. Our results show that video streaming works best for navigation tasks but is more challenging to use for fine-grained searching tasks. Video streaming also creates a very intimate experience with a remote partner, but this can lead to distraction from the 'real world' and even safety concerns. Overall, privacy concerns with streaming from a public space were not typically an issue; however, people tended to rely on assumptions of what were acceptable. The implications are that designers should consider appropriate feedback, user disembodiment, and asymmetry when designing for parallel experiences.


This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 199578, "Validating Ultrasonic Log Response Against Reference Barrier Cells Simulating Downhole Well Conditions Encountered During Well Construction and Abandonment Operations," by Amit Govil, SPE, Schlumberger; Dave Gardner, SPE, Norwegian Research Centre; and Guillermo Obando, Schlumberger, et al., prepared for the 2020 IADC/SPE International Drilling Conference, Galveston, Texas, 3–5 March. The paper has not been peer reviewed.
 Borehole-cement-evaluation logs are used to verify the quality of the cement bond to the casing and formation and identify any defects that could compromise the quality of the annular seal. This study used ultrasonic logging to evaluate reference barrier cells constructed with known defects. The cell concept was developed with an emphasis on low cost and ease of use. Comparison of ultrasonic tool response against reference barrier cells validates the measurements, which are crucial in the decision-making process during well construction and abandonment.
 Background: Barrier Verification
 In 2013 and 2014, full-scale experiments were performed to investigate the sealing ability of annulus cement for a plug-and-abandonment design in which the tubing is left in hole (TLIH). The experimental configurations used 9⅝-in. casing with a 7-in. tubing, both with and without control lines clamped to the tubing surface. Experiments were run first using standard Class G cement. In a second phase, Class G cement with an expansion additive was used to compare the quality of the seal achieved. The barrier quality of the cement was evaluated by pressure-testing the casing cement sheath and the tubing plug. The test assemblies subsequently were cut into sections, enabling the cement displacement to be controlled visually. The results showed that good cement placement could be achieved with the tubing left in the well both with and without control lines. The pressure testing showed that the control lines did not have a detrimental effect on the barrier-seal quality compared with the test without control lines.
 The choice of leaving the tubing in hole when abandoning a well is dependent on an assessment of the quality of the casing cement sheath. The barrier-verification project was initiated to build on the TLIH experiments by investigating the performance of annular-barrier evaluation technologies.
 Materials and Fabrication
 The project aim is to construct a barrier-verification reference facility with the objectives of
 Evaluating technologies for logging through multiple tubulars
 Investigating the performance of commercial logging technologies
 Performing experiments with alternative barrier-verification techniques
 In the first project phase, the TLIH sections were reused as much as possible to enable a starting point with known specifications and quality. The cement plug in the tubing was first removed carefully by hydrojetting. Thereafter, the desired defects, such as long holes of different sizes drilled through the cement immediately adjacent to the 7-in. tubing, were introduced.
 Reference cells were constructed with the aim of mimicking a range of potential annular-leakage scenarios such as gas channels, mud channels, and micro annuli. A design requirement was to enable the required cells to be coupled easily using quick unions in the configuration required to meet the experimental objectives. The tubing-to-casing annulus was sealed such that both the tubing and annulus could be independently pressurized with the required fluid. The pressure rating for the tubing and annulus is 2,200 psi. Pressure ports machined into the annulus bulkheads allow controlled leakage rates to be applied using water or gas.


This paper reports the discovery of a visible, tephra horizon of Late‐glacial age from the site of Loch Ashik in the Isle of Skye, the Inner Hebrides, Scotland. Although the tephra shards have a bimodal geochemical composition identical to that of the Vedde Ash (a well known marker horizon within Late‐glacial sequences. The horizon at Ashik is dominated by basaltic shards and devitrified tephra shards, giving the layer its characteristic black colour. Only rhyolitic shards have previously been reported from Vedde Ash horizons in the British Isles. This new evidence raises some important questions about the factors that govern the distribution and accumulation of basaltic tephra, and about the methods used to detect ash shards in basins distal to centres of volcanic activity.

Emerging in the early 1980s, Taiwanese New Cinema has developed its style as a reflection of Taiwan's history and society, representing the country's colonial past, social transformation, and contemporary cultural development. Consistently projecting history onto the screen, New Cinema creates a journey through Taiwan's past from the colonial era to the present, attempting to represent history in ways which will lead to the exploration and reconsideration of Taiwan's national and cultural identities. With the materials that sustain the national past, the New Cinema of the 1980s presents the very fabric of a national community, perpetuating the idea of the nation itself, the meaning of its culture, and the transformation of its society. But the New Cinema of the 1990s has developed a different tendency, which is largely concerned with present-day capitalist metropolitan culture that no longer bears traces of the country's past. Even the New Cinema directors of the 1980s, such as Hou Hsiao-Hsien and Edward Yang, who were keen to trace Taiwan's history through filmic representation, have gradually moved their concern with historical representation to the focus on urban metropolitan culture since the mid-1990s. (1) The urbanisation of Taiwan provides a dimension for filmmakers to explore modern society, and simultaneously draws a dividing line between the 1980s and 1990s New Cinema productions. Most directors of the 1990s no longer examine history with nostalgia; they seem to be more concerned with the outcome of that history, the urban environment of highly capitalist development, to show their interest in contemporary urban culture, and to turn their camera to the fast-growing Taipei. It is perhaps because the new generation directors have no t experienced the transforming era of Taiwan's society, or because the tight budget for contemporary film productions makes it financially expedient to locate narratives in and near the city, that Taipei is thereby frequently foregrounded in 1990s New Cinema to present the impulse of contemporary urban culture. (2) Viewed as a stage for the social change from the traditional to the modernised, Taipei figures in 1980s New Cinema in order to deal with the dichotomies of city/country, urban/ traditional, examining the process of historical and socio-political shifts, whereas in 1990s New Cinema, Taipei comes to be seen as an urban jungle of infinite possibilities, a stage for a reformulation of the cultural landscape and moral values, and such a portrait of Taipei often appears in Tsai Ming-Liang's films. In contrast with his predecessors' consistent inclinations towards history, Tsai Ming-Liang does not bother trying to understand the process of modernisation and social-economic transformation; instead, he is inspired by the changes in socio-cultural patterns as a result of urbanisation, by which to explore the plenitude of modern culture. As one of the most distinctive filmmakers in contemporary Taiwan, Tsai is remarkably adept at exploring current culture, and his films consistently and obsessively deal with the urban alienation of a society in which people are emotionally blocked and seemingly afloat in a state of loss. Rebels of the Neon God/Qing Shaonian Nezha (1992), Vive, L'amour /Aiquing Wansui (1994), and The River /Heliu (1997), which are linked by a stylistic mood of isolation and thematic motifs such as the disaffected connections between people, form an interconnected trilogy that provides the explicit and detailed impulses through which to explore a contemporary society that has bulldozed its pa st and jerrybuilt its future. Tsai's vision of contemporary culture is elaborated through his portrait of Taipei City, which comes into focus as an implicit protagonist of all his films. In other words, his metropolitan Taipei provides the setting to reflect upon the sound and look of a city and the lives of its people, projecting a cultural model embodied by western capitalist ideology that challenges traditional cultural values by tearing down and rebuilding the moral institutions and disciplines of social orders: the family, the school, and sexual relations. …


Mitochondrial ribosomes from Neurospora crassa have been isolated and characterized by Kuntzel and Noll [1] and by Rifkin et al. [2]. Radioactivity has been found in these ribosomes after labelling of isolated mitochondria by incorporation of 14-C-leucine [1]. However, no distinction was made between labelling of the structural proteins of the ribosomes and the peptide chains being actually synthesized.


Ultra-high-temperature ceramics based on zirconium diboride and silicon and hafnium carbides are presented as composites with ceramic matrix and oxidation-resistant surface. Relatively low density, high strength at extreme temperatures and operability at oxidative environment with temperature up to 2000°C make these materials useful for aerospace construction and power engineering. HfC-ZrB2-SiC-ZrO2 systems are presented, structural analysis and the results of temperature tests in high-enthalpy gas are provided. It was demonstrated that high resistance of HfC-ZrB2-SiC-ZrO2 system to high-temperature corrosion is achieved owing to formation of protective oxide layer with variable composition. A key area for the use of the material in the Arctic is the organization of heat-shielding structures in the oil and gas industry.


This paper critically reviews the recent controversy over the relationship between technology, organizational structure and performance which was stimulated by the work of Woodward. An overview of the discussion is offered and an original evaluation offered on the basis of the latest contributions. This involves a detailed critique of the contribution of Zwerman. The conclusion is that the original Woodward thesis, as stated in the set of propositions for which systematic evidence was presented, should now be viewed as having been disconfirmed by the subsequent research.


Background: Sperm DNA fragmentation is known as an important cause of male infertility. The influence of sperm DNA damage on reproductive potential has been subject of many studies indicating various results and remaining the subject controversial. In this study, we investigated differences of the semen parameters and intracytoplasmic sperm injection (ICSI) outcome according to sperm DNA fragmentation levels (DFLs) of patients. Materials and Methods: The DFLs were determined by Halosperm, a new improved sperm chromatin dispersion (SCD) test. Patients were grouped as low DNA fragmentation group (LFG ≤30%) and high fragmentation group (HFG >30%). Results: Our analysis showed that semen parameters including concentration of untreated sperm and motility of prepared semen were low in HGF, whereas other parameters were not different. Sperm DNA fragmentation levels decreased in both groups after semen preparation by density


The study was conducted to investigate the effects of Ganoderma lucidum (GL) on growth performance, survival rates, and immunocompetence of the weaning pigs. A total of 45, 28-day-old Landrace weaning pigs were randomly divided into three groups of 15 pigs each. A corn–soybean meal-based control diet was formulated and the experimental diets included 0.3% and 0.6% GL powder. The groups were treated for 38 days. Pigs which fed both concentration of GL powder had significantly higher ([Formula: see text]) survival rates than the control group. Besides, pigs which fed 0.3% and 0.6% GL powder had increased lymphocyte proliferation indexes ([Formula: see text]) and the titer of neutralizing antibody against hog cholera (HC) ([Formula: see text]) on day 66 compared with pigs which fed control diet. No differences were found between treatments regarding the average daily gain (ADG), gain:feed (G:F) ratio and diarrhea score. Supplementation of GL powder showed no effects on aspartate aminotransferase (AST) and blood urea nitrogen (BUN), which suggested that GL treatment has no immediate harm on liver or kidney. Based on these results, GL could be suggested as a potential feed additive of weaning pig diets to increase survival rate and immunocompetence.


Sustainability is an idea encompassed with various aspects still under exploration in addition to its vibrant and comprehensive nature. The Brundtland commission articulated that sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs. A plunge for supporting the ideology of sustainability orientations with respect to manufacturing and their implementation are still in need, but the quantum of factors increases in the process of sustainability orientation selection during the implementation of sustainable manufacturing. Several undecided factors are intrinsic in the implementation of new sustainable manufacturing. Decision-making methods using probabilities to represent the three orientations such as alternate material change, manufacturing process change and design change of achieving sustainability cannot be used to prioritize them. Therefore, a fuzzy multiple attribute decision-making (FMADM) method was developed with a three-level hierarchical decision-making models based on the economic, environment and social aspects of sustainable development, to evaluate the three orientations involved in sustainable manufacturing. A case study was conducted in an Indian automotive component manufacturing organization with the FMADM model developed and the results effectively reflected the characteristics of the three orientations of sustainable manufacturing.


In the early stage after the foundation of People's Republic of China, after Soviet Union's way of cultivating qualified medical personnel,China rebuilt the old medical education pattern and founded the framework of higher medical education of PRC.In the 1950s,China had comprehensively learned the guiding thoughts,the teaching policy,as well as the educational programs,the syllabus,the teaching contents and methods of higher medical education from Soviet Union.Because of the special historical background,Soviet Union had brought both advantageous and disadvantageous influence on China higher medical education.Turning over to think,it may give us a helpful lesson for our reform on medical education for the future.


The objective of this master's degree dissertation was to establish a rational design method of the drilling patterns for rock cutting operations with expansive mortar. It is based on Fracture Mechanics. In order to do this, analytical solutions for the Mode I Stress Intensity Factor (KI ) have been developed, based on the techniques of asymptotic analyses of dipoles (for the interaction between holes) and beams (for the interaction between cracks and free surface). The obtained solutions were validated by comparison with Finite Element Method (FEM) results. The resultant criterion can be incorporated easily in electronic spreadsheets and, thus, to be used widely in the industry. Additionally, practical ways for evaluation of the Mode I Fracture Toughness (KIC ), it was a concern. Empirical correlations between KIC and index properties of rocks, obtainable with portable equipments of easy use in field works (Schmidt hammer and Point Load test machine), as well as the density, has been established. Alternatively, an abacus wich becomes possible to evaluate KIC and/or GIC (Critical Strain Energy Release Rate), on the basis of the field measured radial strain and in the length of the cracks propagated from the holes loaded with expansive mortar, also was developed.

Between 2010 and 2012 we took part in a study to assess the practicality of converting the last large-scale sugar cane plantation on Maui Island, Hawaii to biofuels production. The plantation currently has 14,380 hectares of sugar cane under drip irrigation. The irrigation system supplies up to 900,000 m of water per day through a system of 177 km of concrete-line canals and 43, mostly unlined reservoirs, used for temporary storage. Our part of the study was to assess the water loss rate from the irrigation system. Because the unlined reservoirs represent the largest potential loss of water, we started by deploying seepage meters in six representative reservoirs. We found net gain, rather than loss in all reservoirs tested. To explain this surprising result, we collected a toposequence of 2D resistivity profiles from above irrigated cane in the upper elevations of the plantation, down slope across a canal, and then across a reservoir. These profiles show high resistivity (5000 Ohm-m) at the ground surface, up-slope of irrigated cane. Starting at the up-slope-most irrigated cane, there is a down-slope-thickening, lowresistivity (10-200 Ohm-m) layer extending from the surface to depths of 0 to 10 m. At the canal crossing, this layer thickens to 15 m and is less resistive upslope of the canal, but thins and becomes more resistivity down-slope of the canal. Beneath a reservoir, the layer thickens to 20 m, arches beneath the reservoir dam and up to the base of the field beyond. We interpret this low-resistivity layer as a wet zone, fed by irrigation water that has bypassed the cane root zone to form a perchedgroundwater system. Because the canal is concrete lined and extends 3 to 5 m beneath the surface grade, it acts as a barrier to perched water flowing down-slope from above. The reservoir bottom was also excavated below grade. Hence, perched water flowing down slope enters the reservoir along its upslope side. It then flows down and underneath the dam through a narrow belt at the deepest part of the reservoir, where the sealing material forming the base of the perched system was either absent or removed during construction of the reservoir. We conclude that this previously unrecognized perched water system explains the observed widespread lack of leakage from the most of reservoirs and suggests that the bulk of the leakage is occurring in the down-slope parts of the reservoirs and the dam faces. Significant leakage from the canals may be limited to areas of high crack density in the concrete linings. The existence of this perched water system has important implications for the operation of the plantation in an era of increased demands on the fresh water resources of Maui.


A method of testing points generation for the identification and correction of the integral nonlinearity of high performance ADC's is presented. The proposed method is based on averaging all voltages of the multi-resistor voltage divider. The influence of the resistors errors and random errors of the ADC on the residual error of the integral nonlinearity correction for method based on multi-resistor divider is investigated.

The socio-political movement in iran, which led to the revolution in 1979, and hence to the establishment of a new government based upon islamic law came as a complete surprise not only to iranian political scientists but also to those within international circles, who found themselves faced with an unprecedented phenomenon in terms of contemporary political development. In order to understant the structure of socio-political power and the influence of religion upon the process of government, it in necessary to take in consideration the development of the relationship between the state and the remaining components of society, which has played a predominant role in iran's political history. By way of both a retrospective historical approach and socio-political analysis of the above relationship, the aim of this study is to clarify the elements which have favoured the gradual preeminance of the clergy in the political sphere, leading to its eventual monopolisation of the state machinery. Our study demonstrates that with hindsight observations based upon the socio-political movements at the end of the 19 th century, up until the fall of the mossadegh government in the fifties, could in fact predict the nature of this latest development in iran.


Background: Fractures of the distal femur are usually rare and severe , The usual context is a high energy trauma in a young patient and a domestic accident in an elderly person. There are different modalities of management of distal femur fractures among which are the retrograde intramedullary nail and locked compression plate. Both operative stabilizing systems follow the principle of biological osteosynthesis. Aim of the work: To evaluate and compare the outcome of each method of fixation of distal femur fractures as regard; operative time; early mobilization; knee range of motion; time of healing and complications. Materials and methods: This study was conducted on 32 patients attending to El-Helmeya Military Hospital, and Sayed Galal University Hospitals, for comparison between fixation of distal femoral fractures using femoral retrograde intramedullary nails (RN) and distal femoral locked compression plats (LP). The study was conducted between September 2019 and May 2020, The series included 16 cases treated with femoral retrograde interlocking nails (RN) and 16 cases treated with distal femoral locked compression plats (LP). Results: The retrograde nail was superior to locked plate in the aspect of operative time with less operative blood loss and less time to union. Conclusion: Based on this study; accepted outcome had been achieved with both methods compared with results of previous studies. However in our series nail showed better union rate and less surgical morbidities.


The first variable advisory speed (VAS) system in Portland, Oregon, was recently installed on OR-217. This system, designed to be responsive to both congestion and weather, was installed to address issues along the corridor, including unreliable travel times, high crash rates, and substantial declines in performance during adverse weather. To assess the merits and effectiveness of the VAS system, a before and after analysis of corridor performance in terms of capacity, reliability, and safety is being conducted. This paper summarizes the findings of the before analysis and presents results from the after analysis during the first 9 months of operation. Before the system's activation, OR-217 suffered from highly variable travel times, frequent severe bottlenecks, a high rate of rear-end collisions, and significant speed differentials between adjacent lanes. Though the system was activated in the summer of 2014 and the system's long-term effects are not yet definitely established, some notable evidence of travel time reliability improvements has already been documented. The system's safety impacts will be the subject of ongoing analysis.


Carbon nanotubes, made of graphene, one of the world's strongest material, has shown properties that are used in applications such as energy storage devices, electron emission devices, and environmental engineering application. Recently, researchers have focused on determining the effects of carbon nanotubes on soil microorganisms and plants.
Objective: The purpose of this study was to determine if the multi-walled carbon nanotubes will affect the growth of Phaseolus vulgaris as well as inhibit the growth of select soil microbes.
Methods: The effects of Multi-Walled Carbon Nanotubes were determined on bean plants grown under hydroponic conditions and on select soil microbes. Two weeks after germination, the plants were exposed to different concentrations of dispersed multi-walled carbon. The different concentrations were 0 ug (control), 50 \(\mu\)g, 250 \(\mu\)g, 500 \(\mu\)g, 750 \(\mu\)g and 1000 \(\mu\)g mL- 50 \(\mu\)g, 250 \(\mu\)g, 500 \(\mu\)g, 750 \(\mu\)g and 1000 \(\mu\)g mL-1. The growth was reported weekly by measuring the plants themselves, the diameter of the leaf, length and width, the roots, and the fruits. Cultures of Mesorhizobium sp. and Nitrosomonas stercoris were exposed to the 0ug (control), 50 \(\mu\)g, 250 \(\mu\)g, 500 \(\mu\)g, 750 \(\mu\)g and 1000 \(\mu\)g mL-1 of dispersed MWCNTs then incubated in the BioScreen reader. The optical density was reported every 30 minutes for 24 hours.
Results: Our results showed that at 50 \(\mu\)g/mL, bean plants exhibited tolerance to the multi-walled carbon nanotubes whereas at 250 \(\mu\)g/mL and 500 \(\mu\)g/mL of MWCNTs plants showed reduced growth and development and even plant death. Aliquots of 750 \(\mu\)g/mL and above of MWCNTs lowered the microbial biomass. The presence of high concentrations of carbon nanotubes is likely to cause stress to microbes and the direct contact of CNTs with microbes could damage their cell membrane leading to cell death.
Conclusion: As results of this study, the concentration of multi-walled carbon nanotubes should be set at a maximum of 500 \(\mu\)g mL-1 when being released to the soil or environment.


The invention discloses a method and a device for deleting and recovering video files. According to the method and the device, the deletion on the video files can be triggered only through completing the selection on the video files, so that the instant virtual deletion on the video files can be realized, and the personnel privacy of users can be effectively protected. In addition, the logical deletion instead of physical deletion of the video files is realized on the video files in an invisible shielding mode at an application layer, so that the defects of complete relying on a file system, formation of excessive fragmentation spaces in a disc and recovery difficulty of the deleted video files like physical deletion are avoided. Therefore the method and the device can be widely applied to embedded monitoring equipment, the storage abnormality probability of the video files can be reduced, and the deletion caused by misoperation can be easily remedied. Corresponding, the logic recovery on the video files is realized through canceling the invisible shielding of the video files in the application layer, so that the recovery of the video files is simple, and the implementation is easy.


THIS ESSAY READS the life and work of Johann Wolfgang von Goethe alongside the material culture of motherless creations-the automata and androids that his contemporaries imagined and created. Automata and androids are motherless in the sense that men create them, and they represent an attempt to usurp women's primary role in reproduction. Examining Goethe's relationship to the artificial life-forms of his period sheds light not only on the role parentage plays in Faust, a text replete with references to reproduction, but also on the author's relationship to discursive debates around what contemporaries called Erzeugung, "generation." This contextualization of Goethe and Faust in the field of artificial life also helps to better explain the peculiar absence of mothers in eighteenth- and nineteenth-century German writing, a phenomenon that Gail Hart and Susan Gustafson investigate.1 In the Goethezeit, narratives of creation sometimes downplayed women's contribution to the development of the embryo; debates surged between those who believed in epigenesis, the gradual formation of the fetus, and the preformationists, who argued that viviparous animals existed preformed, either in the sperm (spermists) or in the ovum (ovists).2 This essay argues that Faust II ref lects this interest in who contributes more to the creation of new life: the father or the mother.The scene during which Homunculus, a motherless creation, is born satirizes the theory of preformation, if not creation itself.3 Scandinavian scholars have recently pointed out that Goethe's Homunculus in Faust II relates to the contemporary field of artificial life,4 and Jessica Riskin ties eighteenthcentury automata to the philosophical, historical origins of artificial life.5 In The Philosophy of Artificial Life (1996), the premier cognitive science researcher of artificial life, Margaret Boden, defines life as "self-organization, emergence, autonomy, growth, development, reproduction, evolution, adaptation, responsiveness, and metabolism."6 These terms are, of course, modern; in Goethe's time, "creationism" substitutes for "evolutionism," and "vitalism" (translated into Kraft in German)7 for "emergence."8 Traditionally critics have relied on Goethe's Versuch die Metamorphose der Pflanzen zu erklaren (Attempt to Explain the Metamorphosis of Plants, 1790) to explore his concept of generation, while his writings on morphology further establish the author's interest in the form and process of creation.9Generation in Faust I and II is worth reflecting on because life, afterlife, and the redemptive power of love form their thematic core; as Jane K. Brown's allegorical reading of the play suggests, the female figures help redeem Faust's humanity through their love.10 In fact, Faust's female figures remain vehicles for procreation but never quite inhabit their roles as mothers. Conception, birth, and rebirth in Faust I and II happen by artificial means and follow their own fantastical logic. Faust (whose own mother is never mentioned) meets Gretchen after Easter, and by Walpurgis Night, she has presumably given birth, if her apparition is to be believed, and then she drowns her own nameless, sexless child. Faust needs the help of the mysterious Mothers to reach Helena, but they, like other maternal figures in the play (Gretchen's mother; the pregnant Barbel, about whom Lieschen gossips; and Helena's mother, Leda), never appear onstage, and scholars remain perplexed about their function in the tragedy.11 Helena is already dead but comes to life, and she gives birth to a nearly grown Euphorion mere lines after she meets his father. Euphorion, of course, dies when, like Icarus, he flies too high in the sky. Indeed, as Robert Anchor points out, Faust features the loss of children repeatedly: "Mater Dolorosa, Gretchen's mother, Gretchen herself, and Helena all lose their offspring to untimely and violent death."12 In this way, Goethe's depiction of motherhood in Faust places importance on surrogate motherhood, as Ellis Dye suggests: "Gretchen is identified with Helena and she, in turn, with Galatea and with Galatea's mother Aphrodite. …


According to lagging state of water quality monitor and the problems of the difficult of water bloom prediction, water bloom remote monitor and prediction system based on BP neural network are proposed in this paper. This system can realize the automatic real-time monitor for the change of water quality and via the prediction by neural network for water bloom; it can provide a kind of efficient and practical system for water environment control.


Shale gas production is obviously higher within the Silurian Longmaxi Formation than that of the Cambrian Niutitang Formation according to the drilling test results in the northwest Hunan area. To clarify the reasons behind this variation, core samples from the two sets of shales were studied for a comprehensive comparison and analysis of their organic matter (OM) pore structure. Methods were used, including the total organic carbon content test, the vitrinite reflectance test, X-ray diffraction, and focused ion-beam scanning electron microscopy (FIB-SEM). The results show that these two shales have similar reservoir characteristics, both with abundant organic matter and high content of brittle minerals. However, the Longmaxi shale with 2.3% to 3.0%Ro presents lower thermal maturity than the Niutitang shale with over 3.0%Ro. In the case of pore structure associated with OM, a huge difference exists between the two shales. The OM pore shape of the Longmaxi shale is very regular, being mostly round and oval, while the OM pore shape of the Niutitang shale is irregular, being flat with a thin middle and thick and elongated ends. An important factor affecting OM pore evolution is thermal maturity. In turn, the thermal maturity is controlled by the tectonic evolution process, especially the maximum paleo-burial depth. In conclusion, the paleo-burial depth of the Lower Cambrian Niutitang shale in northwest Hunan is too large, which leads to the excessive evolution of organic matter in the shale, and the physical and chemical properties are similar to graphite, which leads to the disappearance of OM pores. Shale gas has no effective reservoir space and is largely dispersed in geological history. At the same time, due to the insufficient hydrocarbon-generation evolution time of the Lower Silurian Longmaxi Formation shale in this area, the shale could not form enough gaseous hydrocarbons and a large amount of effective reservoir space (OM pores with regular shape and large pore size), and finally failed to become a gas reservoir. Therefore, the exploration and development potential of the marine shale gas of the Lower Cambrian Niutitang Formation and the Lower Silurian Longmaxi Formation in northwest Hunan is poor.


We consider a family of marked Poisson process models for the discovery of distinct errors in a computer program and also for sampling, in continu-ous time, a population containing an unknown number of distinct biological species. Captures (selections or discoveries) are assumed to occur at a con-stant rate, each event consisting of the discovery of a distinct process (error or species) or the recurrence of a previously discovered process. Using a generalization of Nayak's (1988) model we derive confidence limits for the discovery rate. The limits are based on the asymptotic distribution of a scaled logarithmic function of the maximum likelihood estimator.


Morphometrical measurements, counts and a short description of the deep-snouted pipefish Syngnathus typhle Linnaeus, 1758 are presented in this paper from specimens caught in Tunisian waters. The occurrence of the species in the area is commented on and discussed.


Large-$N$ quantum systems are known to be dominated by a single classical solution ${M}_{\mathrm{ab}}$, which is the reduced transition matrix among the ground state and relevant "generalized-adjoint" eigenstates. For the one-matrix model, we obtain ${M}_{\mathrm{ab}}$ (and hence the spectrum) for transitions among the ground state and high-lying adjoint states. The method of solution is a new "quasiclassical" quantum mechanics, with no penetration of classically forbidden regions\char22{}yet another classical aspect of the large-$N$ limit.


Objective
To investigate the treatment for patients with high biliary stricture caused by blunt liver trauma.

Methods
Clinical data of 3 patients with high biliary stricture caused by blunt liver trauma in the First Affiliated Hospital, School of Medicine, Xi′an Jiaotong University from January 2007 to December 2011 were analyzed retrospectively. There were 2 males and 1 female with the age of 42, 29 and 34 years old respectively according to the sequence of hospitalization. The informed consents of all patients were obtained and the ethical committee approval was received. All the patients were hospitalized due to gradually aggravated jaundice, accompanied by abodominal pain, fever and elevated alkaline phosphatase after operations of blunt liver trauma. Three patients received computed tomography (CT), magnetic resonance cholangiopancreatography(MRCP), endoscopic retrograde cholangiopancreatography (ERCP) and percutaneous transhepatic cholangiography (PTC), and were diagnosed as biliary stricture of Ⅳ type of Bismuth. Three patients received repeated endoscopic nasobiliary drainage or ERCP stent placement, and the curative effect was poor. The Hepp-Couinaud cholangiojejunostomy was performed to reconstruct the bile duct in 3 patients on 65th, 73rd and 94th d respectively after the operation of blunt liver trauma.

Results
All the operations were successful. One patient suffered mild bile leakage 4 d after operation and was cured by enhanced drainage. The other 2 cases recovered well and were discharged without complications. The patients were followed up for 3, 14, 37 months and no recurrence of biliary stricture or cholangitis were observed.

Conclusions
For the high biliary stricture patients caused by blunt liver trauma, Hepp-Couinaud cholangiojejunostomy should be performed to reconstruct the bile duct after repeated failure of interventional treatments. The best operation time may be 2-3 months after the repair operation for blunt liver trauma.

Key words:
Blunt liver trauma; Abdominal injuries; High bile duct stricture; Portoenterostomy, hepatic


Brown carbon is a type of carbonaceous aerosol with strong light absorption in the ultraviolet and visible wavelengths that leads to radiative forcing. However, it is difficult to correlate the chemical composition of brown carbon with its atmospheric light absorption properties, which translates into significant uncertainty. Thus, a time-dependent density functional theory (TD-DFT) approach was used to model the real-world absorption properties of 14 polycyclic aromatic hydrocarbons (PAHs) over three regions of the Basque Country (Spain): Bilbao, Urretxu, and Azpeitia. The data were corrected for atmospheric concentration. The results show that the absorption spectra over each region are qualitatively identical, with the absorption intensities being significantly higher over Bilbao than over Azpeitia and Urretxu. Furthermore, it was found that the light absorption by PAHs should be more relevant for radiative forcing when it occurs at UVA and (sub)visible wavelengths. Finally, among the 14 studied PAHs, benzo[b]fluoranthene, pyrene, fluoranthene, benzo[a]pyrene, and benzo[k]fluoranthene and benzoperylene were identified as the molecules with larger contributions to radiative forcing.

The existence of inconsistency between clinical and pathological diagnosis of DIC has been pointed out by many authors. Present study was undertaken to clarify this difference and to establish a reliable hemostatic criteria for diagnosis of DIC. A retrospective analysis was done by the investigation of twenty-six autopsies out of 64 cases with DIC which had been clinically diagnosed in our laboratory of Kyushu University School of Medicine from November, 1972 to May, 1979. There were seen malignancies in 22 (85%) and severe infections in 19 (73%), and combination of both diseases in 13 cases (50%) as the underlying diseases of this series. These cases were divided into two groups according to the presence of multiple fibrin thrombi as the pathological evidence of DIC. Microthrombi were detected in 14 cases (Group A), but not in 12 cases (Group B).Decrease of platelet counts, plasminogen and antithrombin-III levels, prolongation of prothrombin time and serial thrombin time, increase of fibrin degradation products (FDP) levels and positive ethanol gelation test were seen in both groups. In these parameters, a significant difference in both groups was seen in only FDP levels, i. e. mean values were 88 and 36μg/ml respectively. In addition, microthrombi were not often detected when a hemostatic criteria of depleted platelet counts less than 100, 000/mm3, increased FDP levels more than 40μg/ml and positive ethanol gelation test are satisfied. Therefore, such a strict criteria shold be recommended in order to make a clinical diagnosis coincidental to pathological evidence of DIC.


This study was designed to investigate the effectiveness of brief group therapy for underachievement, and remediation for deficiencies in basic skills, in reducing the attrition rate of nursing students. Students whose en tering California Test of Achievement scores or GPA's indicated risk of academic failure were interviewed: those with high scores (underachievers) received appropriate therapy, those with low scores and no motivational problems received remediation, and those with low scores plus motivational problems received both (20 hours total for each). Results indicated that a significant decrease in attrition rate can be attained by the foregoing tech niques. THE PROBLEM of student attrition, particu larly in nursing education, has been the subject of much concern and investigation. Investigators have recognized the phenomenon of the under achieve^ that is, a student who scores in the top quarter on ability/achievement measures but whose grades fall in the lower half of his class. The underachiever is, almost by definition, un likely to complete an academic program. It has become increasingly apparent that underachieve ment, rather than lack of ability, is the major cause of student attrition.


Building on the success of employing the analysis of structured data to help solve and prevent crimes, Law Enforcement and Government organizations are seeking to expand the scope of their analysis to include unstructured text data. While typically over 80% of all information available to an organization resides in text form, the analysis has to date been primarily confined to only a structured portion of available data. Missing four out of every five bits of useful knowledge is a very high price to pay for the lack of efficient means for text analysis. An ability to perform in-depth analysis of text data could provide both corporate and government organizations with many new insights. Yet, until recently, such analysis required significant manual labor of reading and coding text narratives — a process too slow and prone to errors. Today, new data and text mining technologies provide a next generation of tools for the analysis and visualization of both structured data and text. Such tools help increase the quality and productivity of the analysis and reduce the latency period between recording raw data and obtaining key knowledge necessary for making informed decisions.


In this paper we present a methodology for the stability analysis of a particular type of event-based control system. In particular, a symmetric send-on-delta technique is employed to generate the events and any single-input-single-output linear time-invariant process is considered. The devised procedure allows the user to find the interval of values of the DC gain of the loop transfer function which ensures that limit cycles do not occur. The technique can be usefully employed to find the range of parameters of an event-based PI controller that ensures the absence of limit cycles in the system. Simulation results show the effectiveness of the methodology.


Next generation autonomous driving functions heavily depend on various computationally intensive algorithms based on machine vision. Design and development of such algorithms is challenging, requiring engagement of a wider community and the availability of appropriate, cost-effective tooling. Setting up a hardware and software environment that would both reflect actual automotive requirements and facilitate development and prototyping, is an uneasy task. In this paper, we analyze the available development platforms which could be utilized in automotive machine vision, with specific regard to new algorithm requirements, such as the utilization of AI, hardware acceleration and low latency. We give a proposal of an affordable and scalable development setup consisting of heterogeneous, vision-enabled SoCs and automotive interfaces.


The 2011 Tohoku Tsunami was observed around Japan by NOWPHAS equipment. These devices include GPS buoys which measure water surface levels by real-time kinematic GPS technology and which are moored at sites 10 km to 20 km offshore where water depths range from 100 m to 400 m, seabed wave gauges at depths between 20 m and 60 m, and coastal tide gauges. A GPS buoy moored offshore of Kamaishi Port recorded the first tsunami crest, which rose in two steps and exceeded 6 m approximately 30 min after the earthquake. Data from some sets comprising GPS buoys, nearby seabed wave gauges, and coastal tide gauges determined the extent of the tsunami propagation and amplification on the coast. Resonance caused by the tsunami continued a day or more after the initial tsunami arrival in some stations. A Doppler-type wave directional meter located in the Tokyo Bay entrance acquired data on the vertically uniform distribution of the tsunami current traveling in and out the bay. The tsunami was detected at almost all of the tide gauges around Japan, even in the semi-closed Ariake and Yatsushiro Bays located on the East China Sea coast of the Kyushu region.

The evolution of a Total Quality Culture within an organisation will include the development of tightly coupled relationships with suppliers. The use of EDI for ordering and delivery communication has grown quickly and fairly naturally in these relationships. However, payment by EDI, for which the supplier is the main beneficiary, is being forgotten. This paper demonstrates the importance of good payment practice and illustrates how this can be achieved more effectively with the support of EDI than by any other means.


A new experimental instrument and date acquisition system for measuring the thermal conductivity of liquid was established based on the transient hot-wire technique.An anodized tantalum wire was used as the sensing element in the cell,and the instrument was suitable for the measurements of electrically conducting or polar liquids.The thermal conductivity of distilled water was measured to test the performance of the apparatus.The results show that the system can be used for the research of thermal conductivity.


Based on chaos game representation of DNA sequence,the authors obtain a 6-component vector whose elements are the leading eigenvalues of corresponding measure matrices to represent the DNA sequence.The correlation distances among introduced vectors are applied to compare the similarities of the coding sequences of the first exon of beta globin gene of 11 different species.The results are basically coincident with their evolutionary relationship.


Abstract—The use of the Multilayer Perceptron Neural Networks (MLPNN) technique is presented to estimate the future state of use of a licensed channel by primary users (PUs); this will be useful at the spectral decision stage in cognitive radio networks (CRN) to determine approximately in which time instants of future may secondary users (SUs) opportunistically use the spectral bandwidth to send data through the primary wireless network. To validate the results, sequences of occupancy data of channel were generated by simulation. The results show that the prediction percentage is greater than 60% in some of the tests carried out.


Young of the cichlid fish Etroplus maculatus actively clean all age groups of Etroplus suratensis. E. suratensis are naturally inhibited from attacking small fish while E. maculatus do so frequently. Cleaning territories are established by the young E. maculatus. Cleaning activity shows a daily circadian rhythm. Removal of fungus from fins and tail appear to be an important adaptive function of this symbiosis. The unique behavior during parental care of both species and other specific behavioral traits may have aided in the evolution of the relationship. This represents the first report of a cleaning symbiosis involving cichlid fish.

As for premature atrial contractions, a common arrhythmia disease, we have designed an ECG detection device based on Convolutional Neural Network (CNN) to achieve real-time monitoring of ECG signals and diagnosis of premature atrial contractions with low cost and capable accuracy. Our work mainly consists of two parts: the system of ECG signal monitoring and the algorithm of premature atrial contractions detection.In the monitoring system, MSP432P401R microcontroller is used to realize the overall system control. ADS1292 bioelectric sensor plays a role in collecting ECG signals and displaying the real-time data on a screen. The microcontroller connects to the PC via serial ports to transfer the data collected, then PC starts performing diagnostics through MATLAB and sending the results to the user by email.The detection algorithm is based on CNN, whose preparation includes the filtering of the ECG signal and QRS demodulation. The QRS demodulation refers to the classical algorithm of Pan, J., aiming to be more accurate through the threshold method. After demodulation, the results are put into a neural network for training which worked out as an accuracy rate of 95.1%, and the performance also reached the requirements. Meanwhile, other schemes are adopted for comparison in this paper, and QRS demodulation is considered superior in the current situation.In conclusion, this paper combined the hardware with convolutional neural network which successfully achieved the real-time ECG detection and accurate diagnosis.


Thick targets of Li2B4O7 containing different concentrations of S have been irradiated with 0.8 to 3.0 MeV protons and 1.0 to 5.0 MeV Ar ions and the K X-ray yields of the S and one projectile (Ar) measured. The K X-ray production cross sections deduced from the measured yields, show a strong dependence on the S concentration in the case of the Ar bombardments. This effect is interpreted as being a consequence of the double-scattering mechanism occurring in the Ar-S collision system.


An approach for belief space planning is presented, where knowledge about the landmark density is used as prior, instead of explicit landmark positions. Having detailed maps of landmark positions in a previously unvisited environment is considered unlikely in practice. Instead, it is argued that landmark densities should be used, as they could be estimated from other sources, such as ordinary maps or aerial imagery. It is shown that it is possible to use virtual landmarks to approximate the landmark density to solve the presented problem. This approximation is also shown to give small errors during evaluation. The approach is tested in a simulated environment, in conjunction with an extended information filter (EIF), where the computed path is shown to be superior compared to other alternative paths used as benchmarks.


The preparation process of DL-thero-p-methylsulfonylphenylserine ethyl ester,using p-methylsulfonylphenylserine copper as raw material and concentrated sulfuric acid as catalyst,was studied in this paper.A study on the factors that influenced the preparation process reveals that the optimal conditions were as follows:n(p-methylsulfonylphenylserine copper)∶ n(concentrated sulfuric acid) ∶ n(ethanol)=1∶ 6∶ 50,the reaction temperature was 83 ℃,the reaction time was 10 h,the crystallization temperature was 0 ℃ and the value of pH,during the process of DL-thero-p-methylsulfonylphenylserine ethyl ester precipitating from ammonia,was 7.5.The yield of DL-thero-p-methylsulfonylphenylserine ethyl ester was approximately 92% under such optimal conditions.Then the DL-thero-p-methylsulfonylphenylserine ethyl ester was recycled from liquid waste which was produced during the esterification process and the process of DL-thero-p-methylsulfonylphenylserine ethyl ester precipitating from ammonia.After that,the yield of DL-thero-p-methylsulfonylphenylserine ethyl ester increased to approximately 98%.The products of the synthesis of DL-thero-p-methylsulfonylphenylserine ethyl ester were analysed and characterized by means of IR,1HNMR and HPLC.Chiral separation of DL-thero-p-methylsulfonylphenylserine ethyl ester was conducted,using D-tartaric acid as chiral selector.The results indicate that the yield of D-thero-p-methylsulfonylphenylserine ethyl ester was 93% under the optimal conditions as follows:n(DL-thero-p-methylsulfonylphenylserine ethyl ester)∶ n(D-tartaric acid)∶ n(methanol)=1∶ 1∶ 50,DL-thero-p-methylsulfonylphenylserine ethyl ester precipitated from ammonia when the value of pH was 7.5.

The Japanese government began providing public telegraph and telephone services in the latter half of the 19th century. After years of service and system development, Nippon Telegraph and Telephone Public Corporation (NTT) was established in August 1952, and has been the provider of domestic public telecommunications services ever since.


In this paper, numerical results for conjugate natural convection flow and heat transfer in a heat exchanger divided by a partition with finite thickness and thermal conductivity are presented using Boungiorno's two phase model. A series of numerical simulation is carried out using the finite volume method over a wide range of the Rayleigh number ( 7 4 10 10   Ra ), volume fraction ( 05 . 0 0   ), diameter ( nm d nm p 145 25   ) and type of the nanoparticles (Cu, Al2O3 and TiO2). In addition, the effects of three types of influential factors such as: thermal conductivity ratio ( 25 1 . 0   r K ), orientation of conductive partition and segmentation of the conductive obstacle on fluid flow and heat transfer characteristics are investigated. Results show that at low Ra, by dividing the conductive obstacle into the nine small segments, the heat transfer rate and absolute values of stream function decrease significantly. It is also observed that by increasing the Ra and thermal conductivity ratio (Kr) the heat transfer rate increase. Moreover, it is found that by changing the orientation of the conductive partition from vertical to horizontal


This paper addresses the blind deconvolution of multi-input-multi-output (MIMO) FIR systems driven by white non-Gaussian source signals. First, we present a weaker condition on source signals than the so-called i.i.d. condition so that blind deconvolution is possible. Then, under this condition, we provide a necessary and sufficient condition for blind deconvolution of MIMO FIR systems. Finally, based on this result, we propose two maximization criteria for blind deconvolution of MIMO FIR systems. These criteria are simple enough to be implemented by adaptive algorithms.

General Secretary Hu Jintao pointed out that we should promote conservation culture when he refered to the new demand of building a moderately prosperous society in all respects in the report of the 17th national congress of CPC.After explaining the conception of conservation culture and the pressing problems of promoting conservation culture in China,this article gradully brought forward the routes of promoting conservation culture in our country.


In capital of Russian empire, St.-Petersburg, on October, 21st, 1832 the Russian diplomat and outstanding scientist Baron Pavel L'vovitch Shilling in his big 5-rooms apartment in the house on Tsaritsyn meadow (now Marsovo pole, 7), has arranged the public demonstration of the first electromagnetic telegraph invented by him. So in Russia there was first-ever suitable to practical use an electromagnetic telegraph. This day now is considered as birthday of Russian telecommunication. In this paper we briefly present the biography of Pavel Shilling, describe how the first electromagnetic telegraph has been invented. We also present academician B. S. Jakobi (1801-1874) who continued works of Shilling and created more perfective electromagnetic telegraphs. Finally this paper shows the evolution of telegraph to the modern communication in Russia.


chine was not used at that time. Dr. Erben organized the dialysis center, and performed the first hemodialysis in 1958 in Hradec Kralove, as at that time the only possible treatment for patients with acute renal failure was dialysis in the Second Department of Internal Medicine in Prague. From his intensive and extensive development in nephrology came the first successful kidney transplantation in Czechoslovakia in 1961; he was one of the persons whose lifetime effort was to find the optimal form of renal replacement therapy. He was creative in the field of renal replacement therapy, organizing the dialysis center and increasing the number of patients with chronic renal failure on dialysis. He introduced the regular treatment of patients who previously would have died as there was no chronic dialysis program in Czechoslovakia at that time. In 1956, he was given his first degree in internal medicine and the second degree in internal medicine in 1959. Dr. Erben was nominated Assistant Professor in 1959; he defended his doctoral degree in 1964, and after defending his habilitation thesis he became Associate Professor of Medicine in 1965. In the same year he was nominated as head of the First Medical Department in Hradec Kralove and gained clinical qualification in the USA (ECFMG). He became a Doctor of Sciences in 1982. In 1966–1967 he worked as a fellow at Prof. Kolff 's Department of Artificial Organs at the Cleveland Clinic Foundation in Ohio, USA. Willem Kolff is known as a father of the artificial kidney. Here Erben became acquainted with the methods of dialysis treatment, special care after kidney transplantation, and exerted huge effort in the development of a new kind of artificial kidney. In his request asking for prolongation of Erben's stay in Recently, among my old papers I found a bluish card with a distinctive signature, Erben; Prof. Erben's pronounced, firm and energetic handwriting is renowned and has not changed since. The document was from the Department of Anatomy of the Medical Faculty in Hradec Kralove where I was a student in 1948 and performed an autopsy under Prof. Erben's inspection. That signature, which I have come across under various circumstances throughout my life, a graphologist would characterize as a sound marker of a systematic, energetic, and creative personality with a firm and unflinching character. My lifelong contact with Josef Erben, at first on a daily basis during our collective work at the First Department of Internal Medicine in Hradec Kralove, and later occasionally at the scientific or friendly level, is firm confirmation of this. Therefore, a laudation on the occasion of such a significant anniversary cannot be fulfilled without a brief mention of his curriculum vitae. Josef Erben was born on May 24, 1926, the son of a general practitioner who later moved with his family to Ostromer. He studied medicine at the Medical Faculty in Hradec Kralove, and graduated from Charles University in 1951. On leaving the military service, he started his medical career at the local hospital in Nova Paka. This experience was most useful for his later professional life. In 1955 our teacher and head, Prof. Rehor, engaged Josef Erben in his clinic on the basis of a competition and in great appreciation of his clinical experience. He appointed Dr. Erben to focus on nephrology including organizational work. At the Department of Surgery an artificial kidney machine, the Moeller Hamburg, waited, which Prof. Bedrna, a surgeon with urological interest, had brought to Hradec Kralove.

This chapter investigates how both Constantine and Julian used building works as a means to support their religious programs, with construction and demolition of churches and temples. It unveils the intentions of the two rulers — revealing that Julian's efforts were not mere coincidence but a direct attempt to reverse his hated uncle's Christianization. The chapter also examines the impact of the awareness of Constantine's demolishing and desecrating pagan sites and Constantius's later antipagan laws to Julian. It then highlights the three key places of Julian's program of construction: Constantinople, Antioch, and Jerusalem. The chapter looks at the evidence provided by a close contemporary concerning Julian's revival in order to understand how Julian restored pagan worship in the former city of Byzantium. It then elaborates on the restoration of the Jewish Temple in Jerusalem, and the introduction of the "pagan church" in Antioch.


In the Glass Video Gallery, the "translucent condition" of the architectural space – both physical and metaphorical – and its capacity to activate the perception, imagination and other modes of occupancy, is at the same time effective, transgressive and displaced from the traditional notion of place. Several degrees of transparencies, illusions, dissolutions and perceptive instabilities are generated that introduce imprecise limits, activating for the visitor and/or spectator an experience between the real and the virtual realm, provided by the overlapping and varying speed of flows, images and reflections that are generated, particularly when the videos are played, and it is open to the public. Dissolved are opacities, precise visible limits, the coordinates of the body and space, and the sole temporal condition since many temporalities overlap one another: that of the city, the path, the visual and sound flows, those of thoughts, feelings, emotions, etc. Between cognition, imagination, emotion and perplexity, the subject builds his or her perceptive field and inhabits the place multidimensionally, with the sensation that something is being transgressed. Subject and object are in opposition to one another, intercepting and interacting in the same imprecise space. The architectural space is established dynamically at every moment in-between the dissolution, dislocation and coherence of the perceptive reality, which becomes plural, imprecise and always different. Object and subject, space and event, art and architecture interact to construct the place. It is an interstitial place that, governed by a conception of a more inclusive and complex order, ultimately acquires the status of an objectplace-event. A place of ambiguity, reverberation and reversibility, where the artistic and architectural are intentionally blended together, where the object/the construction and the urban dialogically interpenetrate each other, and where the mind and vision waver between cognitive visibility and invisibility of the unconsciousness, evoking the ambiguous and spectral revelation of Duchamp ́s Large Glass and the optical unconscious described by Rosalind Krauss. The shape, the glass and the virtual aspects dissolve the threedimensional illusion of the perspective and reconquer the flat surface (as done by Picasso and Cubism). Space is fragmented, reverberated or expanded, and the observer is called upon to form part of the scene. The perception now ubiquitously "withdraws" and wavers between a global experience (panoptic and "panhaptic") and another partial or fragmented one, and the body wavers affectively between a sort of "non-figure" and "non-background". It is an experience that reminds us of the Piranesi's Imaginary Prisons or the sketching process of Giacometti; a sort of "poly-perspective hyper-reality" is generated, without any precise limits or shame. A "hyper-reality" that criticises the primacy of vision (of optics) and the sense of modern Western cultural tradition. Like a hypertext, the gallery manifests our current media-cultural, mechanical and electronic paradigm at the same time, characterised by the complexity, diversity, simultaneousness, multiplicity, velocity and interactivity. It is established as a figural in-between place with blurry or imprecise limits, where the subject and object, spectator and show, space and event, culture and nature, art and architecture overlap in multiple dimensions. In an evocation of intelligence, creativity and fantasy in architecture, an attempt is made to dissolve the strict and direct legibility of the perception, and a call is made to a more interactive and evocative experience of the place.


An interesting pharmacological approach in terms of anti-suicidal strategies is the use of lithium for treatment of patients with affective disorders. Details here.


The photosensitivity of the photosurface deposition (PSD) effect and the durability in air of Agx(Ge0.3S0.7)100−x films (40⩽x⩽83) with thicknesses of 50–700 nm have been studied. Films of 60–65 at. % Ag and 200–300 nm thick were found to be optimal for applications in optical recording devices. Crystallized samples have been examined to obtain structural information on the Ag-rich films. It is suggested that excess Ag+ ions, which contribute to the PSD, exist in a disordered Ag8GeS6 phase of the Ag-rich films.


Based on the statistics of Shandong Province, ecological economics approach was used to calculate the positive and negative services value of farmland ecosystem and its spatial and temporal change, and then gray correlation theory was used to analyze its influencing factors. The results suggested that the positive and negative services value of the farmland ecosystem increased, and the average positive value increased 55.2×108yuan, the negative value resulted from environmental pollution was the highest which ranges between 174.94×108~299.35×108yuan. The negative value of the fertilizers and pesticides had decreased and the proportion of the negative value of the plastic film was increasing year by year. The services values of farmland ecosystem in 2011 was different among regions, of which Linyi's positive value was the highest, Heze's negative value resulted from greenhouse gas emissions was the highest, for water consumption, Jining and Dezhou rated as the first and two. The water using and the planting areas of the crops and the effective irrigation area had a relatively higher influence on the agricultural production. The use of pesticides and chemical fertilizer on the farmland had a positive value, but a negative impact on the farmland services.

The invention relates to a portable cardio-pulmonary resuscitation device based on sign information fusion. The portable cardio-pulmonary resuscitation device comprises a pressing device, a sign detection and intelligent control device and a man-machine interface. The pressing device presses a human body. The sign detection and intelligent control device comprises a detection unit and a controller unit. A sign detection system, a man-machine interaction module and a specialist system are introduced to a human body cardio-pulmonary resuscitation system, and the practicability, portability and self-adaptability of the system are improved. Due to the fact that the sign detection system is introduced, rescuers who do not have corresponding emergency medical aid knowledge can still visually observe the physiological information states of patients, and effective treatment judgment foundations are provided for experienced rescuers. By means of the man-machine interaction module, the rescue time waste caused by operation is reduced; by introducing the specialist system, the patients can be automatically rescued through the human body cardio-pulmonary resuscitation system; by means of the self-adaption method, the first-aid performance is improved, and it is ensured that the first-aid is accurate and stable.


Archaeologists have long noted similarities between the lithic artifacts of the first colonists of the Greater Antilles (ca. 3500-2000 B.C.) and those from the eastern Yucatán Peninsula. Recent archaeological work in northern Belize has provided additional archaeological information on the characteristics and dating of the mainland assemblages. New findings by Caribbean archaeologists also have contributed to a clearer picture of the circumstances surrounding the first human migration to the Greater Antilles. A Yucatecan origin for the first Caribbean migrants is now considered probable.

To form a master bit stream that can scale adjustment so as to form a scale adjustment bit stream having a data rate defined arbitrarily, a method of compressing an audio input signal. Hierarchical filterbank (2100) decomposes the input signal, a time / frequency representation of the multi-resolution both can be efficiently extracted tonal component encoder from which (2106) and residual components (2117). These components are ranked, and then are quantized with reference to the same masking function or different psychoacoustic criteria. Tonal components selected may be adequately coded using differential encoding, which is extended to multi-channel audio. Time constitutes the remaining component - sample and scale factor components are coded using joint channel coding was extended to multi-channel audio (JCC). Decoder uses an inverse hierarchical filterbank to reconstruct the audio signal from the tonal components and the remaining components in the scale adjustment bitstream. .The 21


On 11 April 2007, the European Commission presented its Communication entitled Black Sea Synergy: A New Regional Cooperation Initiative. This Communication reflected the influence of a combination of factors that have led the European Union (EU) to consider greater engagement in the Black Sea region. Most importantly, the enlargement of the EU in May 2004 and January 2007 brought the Union geographically to the coastline of the Black Sea itself. The Black Sea raises high stakes in the EU as it works to become a foreign policy actor. The complexity of engaging in the region is exacerbated by an additional factor—the existence of four self‐declared 'states': the Pridnestrovyan Moldovan Republic (PMR) inside Moldovan borders, the Republic of South Ossetia, the Republic of Abkhazia, within Georgian borders, and the Nagorno‐Karabakh Republic in Azerbaijan. This article explores three questions raised by the existence of these de facto 'states'. First, the discussion examines briefly the concept of the de facto 'state'. Second, what has sustained these non‐recognised entities since the collapse of the Soviet Union? This section examines the particular importance of fear as a sustaining force. And third, what is the security impact at the individual, state and regional level of the de facto 'states'? All three questions are relevant for the EU as it becomes more deeply engaged in the Black Sea.


Graphical procedures and rules of thumb have been presented so far to estimate size and cost for horizontal separators, treaters, compressors, gas desulfurizers, glycol dehydrators, flow lines, manifolds, LACT units, and storage/surge tankers. The processing units included in this list are pre-engineered assemblies, shop fabricated to minimize field cost. Cost estimates include engineering, material and plant labor, FOB factory. Additional costs for freight, field materials, field labor, and installation must be estimated. The summation method shown determines these missing items and gives a grand total cost for the sample oil-field installation. A summary of example cost estimates for a typical oil field facility is shown by tabular data. This table is divided into the plant costs and nonplant costs. This method, with minor changes, can be used to estimate cost of installations in other countries or off shore. The example estimate was developed, assuming the facility would be installed in Louisiana. The same factors should apply to any domestic location.


In our study, three phenomenological strength criteria (the von Mises criterion, the Tsai-Wu criterion, and the Ashkenazi criterion) were compared based on experimental data. The goal of this study was to decide which strength theory describes properly the failure of wood under biaxial load. Formerly, a set of biaxial tests was performed on Norway spruce (Picea abies [L.] Karst.) specimens. As a result hundreds of biaxial strength data are available. Failure criteria were validated in these planar stress states. Theoretical and experimental background was presented and tensor components were calculated from engineering strength for each strength criteria. Failure prediction data was determined by the three theories. The results show that out of the three criteria the Ashkenazi strength criterion best describes the failure of wood in planar stress state.


Hough Transform(HT) is widely used in computer vision by its transformation from image space detection to parameter space accumulation.A new algorithm for detecting circle contour based on HT is proposed.Using this method,the information of grayscale and gradient is used simultaneously, the sample in image space is constrained and optimized,the amount of accumulator is minimized,the contour point belonging to the object is attained,the dummy point is picked out by re-searching contour according to the geometric property of object,the computing speed is accelerated through multi-one mapping and parallel algorithm.The result of experiment shows that the algorithm can be used in the image with low contrast and spoiled by noise,the uncertainty is less than 0.15 pixel,and the computing speed is twice comparing the classical Random Hough Transform(RHT).


The new Traffic Management Act in the UK has introduced new statutory obligations for local authorities. The Urban Traffic Management and Control (UTMC) framework can be used by local authorities to design systems in which the different applications of a modern traffic management system can communicate and share information with each other. The history of the UTMC and its aims are outlined. The structure of the UTMC Development Group (UDG) is described. The policy, operational and financial benefits associated with UTMC are listed. The use of UTMC in York, Lancashire, Glasgow, South Yorkshire, Reading and Stoke-on-Trent is described with reference to variable message signs, park and ride, traffic signal strategies, pollution monitoring, public transport, car parks, passenger information, and fault reporting systems. Links between UTMC with the Travel Information Highway (TIH) and Real Time Information Group (RTIG) are discussed.

The purpose of this study is to determine whether magnetic resonance imaging(MRI) can assist in deci- sion-making in the treatment of acute posterolateral complex injuries. We reviewed retrospectively seven patients with acute posterolateral complex injury, among the 79 cases that had taken cruciate ligament recon- struction. MRI findings were then correlated with the results of examination under anesthesia or operi lateral reconstruction. Based on surgical and clinical findings, there were six complete and four partial posterolateral complex injuries. MRI was able to accurately describe the extent of injury in each case. All ten patients had concomitant anterior cruciate ligament tears, and seven were three posterior cruciate ligament injuries. The iliotibial band was avulsed from Gerdys tubercle in seven patients. In knees with complete tears, separation of the coronary ligament of the lateral meniscus was noted on MRI. A characteristic bone contusion on the anteromedial femoral condyle was present in nine patients. Popliteal tendon tearing was observed in eight cases, and biceps femoris was torn in six patients. In knee with complete tears, tears of the lateral collateral ligament complex was noted both on MRI and intraoperatively. A high-quality MRI in patients sustaining these injuries will assist the surgeon in directly applying surgical techniques in a timely fashion.


If the viscosity of a fluid in plane Couette flow decreases exponentially as its temperature increases, the curve of wall speed versus wall stress has two branches, separated by a turning point. Our aim is to demonstrate that the upper branch of this curve is stable to zero wavenumber disturbances in case the power supplied to move the wall is the input variable and is held fixed.


ABSTRACT Yield, dry matter production, nitrogen (N) uptake and nitrogen use efficiency (NUE) of Bangladesh Rice Research Institute (BRRI) dhan29 were investigated during two consecutive dry (Boro) seasons of 2009–10 and 2010–11. The experiments were set up in a randomized complete block design with three replication having six nitrogen (N) levels of 0, 40, 80 120, 160 and 200 kg ha−1. Nitrogen fertilization increased yield characters, dry matter production and N uptake. The economic optimum rate of N was 166 and 155 kg ha–1 in first and second year, respectively, with corresponding yield of 7.1 and 6.5 t ha−1. NUEs were higher in the first year, decreased with increasing N rates in most cases. Gross return over fertilizer reached the highest Tk 692 in 2009–10 and Tk 489 in 2010–11 with 160 kg N ha–1. The results suggest that BRRI dhan29 should receive an average of 160 kg N ha−1 for economic optimum yield.


Dense arrays of vertically aligned multiwalled carbon nanotubes (MWCNTs) have been seeded with a nanodiamond suspension in methanol using electrospray deposition. This treatment caused the tips of groups of 20–40 MWCNTs to stick together forming structures resembling "teepees." Subsequent short chemical vapour deposition experiments using standard diamond-growing conditions allowed the nanodiamond seeds to grow into a thin continuous film, locking the teepee structures into this shape. Field emission tests show that these diamond-coated carbon nanotubes (CNTs) teepees retain the low threshold voltage of the uncoated CNTs but with greatly improved emission stability and lifetime.
