    2015-07-01

    The weaving section, as a typical bottleneck, is one source of vehicle conflicts and an accident-prone area. Traffic accident will block lanes and the road capacity will be reduced. Several models have been established to study the dynamics around traffic bottlenecks. However, little attention has been paid to study the complex traffic dynamics influenced by the combined effects of bottleneck and accident. This paper presents a cellular automaton model to characterize accident-induced traffic behavior around the weaving section. Some effective control measures are proposed and verified for traffic management under accident condition. The total flux as a function of inflow rates, the phase diagrams, the spatial-temporal diagrams, and the density and velocity profiles are presented to analyze the impact of accident. It was shown that the proposed control measures for weaving traffic can improve the capacity of weaving section under both normal and accident conditions; the accidents occurring on median lane in the weaving section are more inclined to cause traffic jam and reduce road capacity; the capacity of weaving section will be greatly reduced when the accident happens downstream the weaving section.

    In these proceedings we highlight the primary scientific goals and design of the WEAVE-LOFAR survey, which will use the new WEAVE spectrograph on the 4.2m William Herschel Telescope to provide the primary source of spectroscopic information for the LOFAR Surveys Key Science Project. Beginning in 2018, WEAVE-LOFAR will generate more than 10$^6$ R=5000 365-960 nm spectra of low-frequency selected radio sources, across three tiers designed to efficiently sample the redshift-luminosity plane, and produce a data set of enormous legacy value. The radio frequency selection, combined with the high multiplex and throughput of the WEAVE spectrograph, make obtaining redshifts in this way very efficient, and we expect that the redshift success rate will approach 100 per cent at $z < 1$. This unprecedented spectroscopic sample - which will be complemented by an integral field component - will be transformational in key areas, including studying the star formation history of the Universe, the role of accretion and AGN-d...

    2014-04-01

    Full Text Available The project “Design, craft and culture” had the purpose of co-production of knowledge between the University of Borås and the small-scale enterprise Vävkompaniet (The weaving company. The practitioners’ wanted to get insights into competences previously “hidden” in their knowledge in action; competences that could be the base for development of products and ways to reach customers. From academic point of view the main goal was to produce films aimed shedding light on knowledge in action. The result is four educational films aimed at students.This article is based on interpretations of films and interviews from places where the handweavers produce their products. A researcher and a weaving teacher studied their work, while the photographer filmed the artisans’ body movements. Questions and words, in a language which fits the events of the practice, can make practitioners sharpen their attention and direct it at critical points in the practice that they accomplish. By interviews done in a conversation-like way during observations, a space for such reflections was created. The weavers shared meanings on their position in the field of craft and detailed descriptions of crafting practices with the research team. Regarding the design process, because of their material rather than conceptual approach to craftwork, the weavers brought up the importance of sample weaving. While work with dressing the looms and weaving then continued many empirical examples of aspects of knowledge in action could be observed. The importance of routine, rhythm, bodily skills, senses, judgement and experience are brought up in the text.Key words: textile craft, weaving, tacit knowledge, knowledge in action, senses, visual ethnography

  19. Warp Breaks Detection in Jacquard Weaving Using MEMS: Effect of Weave on Break Signals

    2008-03-01

    Full Text Available This paper reports a study to detect warp breaks in terms of weave structure using MEMS accelerometer based detection system. The system is briefly described. The output signals of MEMS sensors, which were mounted on harness cords of a Jacquard machine, at the moment of warp yarn break and after the break for a broad range of basic weaves were acquired during weaving. The weaves investigated are commonly used in Jacquard weaving to form patterns. The strength of the MEMS output acceleration signals was analyzed in time domain. The results show that the system is capable of detecting warp yarn breaks for the broad range of weaves studied.

    A need exists for artificial muscles that are silent, soft, and compliant, with performance characteristics similar to those of skeletal muscle, enabling natural interaction of assistive devices with humans. By combining one of humankind’s oldest technologies, textile processing, with electroactive polymers, we demonstrate here the feasibility of wearable, soft artificial muscles made by weaving and knitting, with tunable force and strain. These textile actuators were produced from cellulose yarns assembled into fabrics and coated with conducting polymers using a metal-free deposition. To increase the output force, we assembled yarns in parallel by weaving. The force scaled linearly with the number of yarns in the woven fabric. To amplify the strain, we knitted a stretchable fabric, exhibiting a 53-fold increase in strain. In addition, the textile construction added mechanical stability to the actuators. Textile processing permits scalable and rational production of wearable artificial muscles, and enables novel ways to design assistive devices. PMID:28138542

    Full Text Available Introduction: This study aimed to investigate the effect of carpet weaving at a proposed workstation on Upper Trapezius (UTr fatigue during a task cycle. Fatigue in the shoulder is one of the most important precursors for upper limb musculoskeletal disorders. One of the most prevalent musculoskeletal disorders between carpet weavers is disorder of the shoulder region. Methods: This cross-sectional study, included eight females and three males. During an 80-minute cycle of carpet weaving, Electromyography (EMG signals of right and left UTr were recorded by the surface EMG, continuously. After raw signals were processed, MPF and RMS were considered as EMG amplitude and frequency parameters. Time series model and JASA methods were used to assess and classify the EMG parameter changes during the working time. Results: According to the JASA method, 58%, 16%, 8% and 8% of the participants experienced fatigue, force increase, force decrease and recovery, respectively in the right UTr. Also, 50%, 25%, 8% and 16% of the participants experienced fatigue, force increase, force decrease and recovery, respectively in the left UTr. Conclusions: For the major portion of the weavers, dominant status in Left and right UTr was fatigue, at the proposed workstation during a carpet weaving task cycle. The results of the study provide detailed information for optimal design of workstations. Further studies should focus on fatigue in various muscles and time periods for designing an appropriate and ergonomics carpet weaving workstation

    Full Text Available Long-time monitoring of physiological parameters can scrutinize human health conditions so as to use electrocardiogram (ECG for diagnosis of some human’s chronic cardiovascular diseases. The continuous monitoring requires the wearable electrodes to be breathable, flexible, biocompatible, and skin-affinity friendly. Weave electrodes are innovative materials to supply these potential performances. In this paper, four conductive weave electrodes in plain and honeycomb weave patterns were developed to monitor human ECG signals. A wearable belt platform was developed to mount such electrodes for acquisition of ECG signals using a back-end electronic circuit and a signal transfer unit. The performance of weave ECG electrodes was evaluated in terms of skin-electrode contacting impedance, comfortability, ECG electrical characteristics, and signal fidelity. Such performances were then compared with the values from Ag/AgCl reference electrode. The test results showed that lower skin-electrode impedance, higher R-peak amplitude, and signal-to-noise ratio (SNR value were obtained with the increased density of conductive filaments in weave and honeycomb weave electrode presented higher comfort but poorer signal quality of ECG. This study inspires an acceptable way of weave electrodes in long- and real-time of human biosignal monitoring.

The new approach applies linear least-squares and works on gridded maps from arbitrarily sampled data, which greatly improves computational efficiency and robustness. It also allows masking of bad data, which is useful for cases where radio frequency interference is present in the data. We evaluate the algorithms using simulations and real data obtained with the Effelsberg 100-m telescope.

    Card weaving is a simple, easy weaving method, but designing patterns is typically laborious and requires knowledge, experience, and skill. The Weavy system helps users design and weave original patterns with or without repeating elements. In the latter case, the system automatically considers constraints such as the number of yarn colors and the cards' rotation direction. Following Weavy's construction guide, users weave the pattern they've created. Researchers exhibited Weavy at the ACM Siggraph 2013 Studio and ran a small workshop for children in Japan. In both cases, the participants quickly learned how to use Weavy and enjoyed designing and weaving objects.

  12. Air Consumption Analysis of Air-Jet Weaving

    RAJ KUMAR KHIANI

    2016-07-01

    Full Text Available In Textile industry, production is mostly key concern for Industry owner. This always has attracted researchers and machines manufacturers to make new developments in process and machines. Air-jet is one of the leading and successful highest productive weaving machines. However, it is now well established that due to add of charges of compressed air, manufacturing cost of air-jet weaving machine is higher as compared with rapier and projectile weaving machines. This is why countries having energy issues do not prefer air-jet weaving machines comparing projectile weaving machines. In this regard, several researchers and machine manufacturers have continuously been working to improve the efficiency of air-jet weft insertion. However, industry practice is as important as design made by researchers. The aim of this research is to investigate the air consumption of air-jet weaving on industrial scale practice. In this study, five weaving machine of same manufacturer and model were selected. It was observed that despite of manufacturing same quality of fabric, air consumption was varying almost in all weaving machines. Conventionally, mill workers adopt hit and trial practice in weaving industry including airpressure setting which leads to variation of nozzle pressure. Main reason of disparity of air consumption in air-jet weaving machines may be variation of distance from compressor to weaving machines, number of joints, un-necessary valve opening and pipes leakages cause an increase of compressed air consumption.

    WEAVE is the next-generation wide-field optical spectroscopy facility for the William Herschel Telescope (WHT) in La Palma, Canary Islands, Spain. It is a multi-object "pick and place" fibre fed spectrograph with more than one thousand fibres, similar in concept to the Australian Astronomical Observatory's 2dF1 instrument with two observing plates, one of which is observing the sky while other is being reconfigured by a robotic fibre positioner. It will be capable of acquiring more than 10000 star or galaxy spectra a night. The WEAVE positioner concept uses two robots working in tandem in order to reconfigure a fully populated field within the expected 1 hour dwell-time for the instrument (a good match between the required exposure times and the limit of validity for a given configuration due to the effects of differential refraction). This presents additional constraints and complications for the software that determines the optimal path from one configuration to the next, particularly given the large number of fibre crossings implied by the 1000 fibre multiplex. This paper describes the algorithms and programming techniques used in the prototype implementations of the field configuration tool and the fibre positioner robot controller developed to support the detailed design of WEAVE.

    Polymer matrix composites are increasingly used in various industrial sectors to reduce structural weight and improve performance. Woven (also known as textile) composites are one class of polymer matrix composites with increasing market share mostly due to their lightweight, their flexibility to form into desired shape, their mechanical properties and toughness. Due to the viscoelasticity of the polymer matrix, time-dependent degradation in modulus (creep) and strength (creep rupture) are two of the major mechanical properties required by engineers to design a structure reliably when using these materials. Unfortunately, creep and creep rupture of woven composites have received little attention by the research community and thus, there is a dire need to generate additional knowledge and prediction models, given the increasing market share of woven composites in load bearing structural applications. Currently, available creep models are limited in scope and have not been validated for any loading orientation and time period beyond the experimental time window. In this thesis, an analytical creep model, namely the Modified Equivalent Laminate Model (MELM), was developed to predict tensile creep of plain weave composites for any orientation of the load with respect to the orientation of the fill and warp fibers, using creep of unidirectional composites. The ability of the model to predict creep for any orientation of the load is a "first" in this area. The model was validated using an extensive experimental involving the tensile creep of plain weave composites under varying loading orientation and service conditions. Plain weave epoxy (F263)/ carbon fiber (T300) composite, currently used in aerospace applications, was procured as fabrics from Hexcel Corporation. Creep tests were conducted under two loading conditions: on-axis loading (0°) and off-axis loading (45°). Constant load creep, in the temperature range of 80-240°C and stress range of 1-70% UTS of the

    Full Text Available In the article weaves and colours of Lithuanian folk skirts fabrics are analysed. The investigation objects are the skirts from funds of three Lithuanian Museums: 258 skirts from National M. K. Čiurlionis Museum of Art, 85 skirts from Lithuanian Open Air Museum and 16 skirts from A. and A. Tamošaitis gallery “Židinys”. Distribution of skirts fabrics according to weaves was estimated, and it shows, that fabrics of plain weave are most widespread (53 %, combined and twill weaves are less popular (19 % and 18 %, respectively. The weaves of fabrics are determined during investigation and plans of weave were made proposing recommendations for manufacturing of similar fabrics. Also distribution of colours and number of colours in the fabrics were analysed. The biggest number of colours is in fabrics of simple weaves (plain and twill, and the most characteristic are green, red, black and blue colours. DOI: http://dx.doi.org/10.5755/j01.ms.19.3.5240

  4. Stick-Weaving: Innovative Behavior in Tamarins (Saguinus oedipus).

    Snowdon, Charles T; Roskos, Thomas R

    2017-03-09

    Some captive cotton-top tamarins spontaneously weave sticks in the mesh of their enclosures so that the stick is lodged between two mesh openings. Sticks are broken from natural branches placed in the enclosures and often modified by biting them in the center before weaving through the mesh. To investigate this further, we systematically surveyed all animals in our colony and found that all successful stick-weaving tamarins were descendants from only 2 of the 16 breeding groups contributing to the colony membership at the time of surveying or were the mates of these descendants, suggesting stick-weaving is a socially learned behavior. Successful stick-weavers were presented with pipe cleaners, soda straws, and wooden dowels to see if they would generalize stick-weaving to novel objects. Seven of 10 animals successfully wove with straws or pipe cleaners, showing that they could generalize the behavior to objects that were physically different but had the same affordances as the sticks. Data from a father-daughter pair suggest a form of coaching. Innovative behavior is needed for the emergence of culture with subsequent social transmission. Although innovative behavior in primates is mainly associated with foraging and is more likely to occur among males, stick-weaving has no obvious reward and appeared equally in both sexes. Stick-weaving behavior and its probable social transmission across generations suggest the possibility of cultural traditions emerging in this species. (PsycINFO Database Record

    Using the metaphor of a fabric woven from many threads, this paper describes nine of the many conceptual strands that have contributed to the development of child psychoanalysis over its first century. It notes the unfortunate isolation (sometimes self-imposed) of child analysis from related fields (including adult analysis) and argues that we must recognize both the strengths and weaknesses of our psychoanalytic tools if we are to collaborate with and profit from the work of nonanalytic colleagues. It closes with the suggestion that the continued weaving of child analysis will require the creation of new looms, structures that are able to support a new generation of child analysts and the continued elaboration of the field.

    The Ming dynasty (1368 - 1644) inherited the long-standing culture in China, of course including the textile technology.Besides a large amount of single color damask silk, many pattern woven silk including dragon robes, patterned costumes and luxurious silk textiles are found in complicated and colorful pattern woven brocade called zhuang hua. It was prevailed in Ming dynasty when compared with the frequency of the name zhuang hua recorded in related historical documents. These pattern silk and brocade were produced by the advanced pattern weaving technology,which was well developed in Ming dynasty. From historical documents of "Tian gongkai wu", Exploitation of the works of nature, there is the detailed description of the draw loom (hua lo ji) which can weave normal patterned textiles. It also indicated that to produce dragon robes needed much more high technique, similar to the hua lo ji but more complicated and difficult. A big draw loom is found to weave Nanjing Yun brocade today inherits the technology to weave zhuang hua brocade. After sorting the historical documents,it is found that some records are coincident with the existed materials, both the silk textiles and weaving technology.With these evidences research and exploration, this dissertation tries to unravel the pattern weaving technology in the Ming dynasty.

  13. Effect of Yarn Distortion on the Mechanical Properties of Fiber-Bar Composites Reinforced by Three-Dimensional Weaving

    Science.gov (United States)

    2016-04-01

    A meso-structure model of fiber-bar composites reinforced by three-dimensional weaving (FBCR3DW) is proposed. Optical microscopy images of the preform structure revealed that the fibers along the circumference of the yarn cross-weave were twisted randomly due to alternating yarn winding on either side of the fiber bars during the manufacturing process. Sections of the cross-woven yarn were divided into five regions based on the twist characteristics. Stochastic function theory was used to describe the twist characteristics and to calculate the compliance tensor for each twisted yarn region. The twist characteristics and compliance tensor of each region were then introduced into a finite element model to calculate the elastic properties of the twisted yarn and FBCR3DW; unidirectional tensile stress-strain curves were generated based on the Tsai-Wu failure criterion. Several FBCR3DW specimens with randomly twisted yarns inside the weave structure were used in experimental tests. Our numerical results were in good agreement with the experimental values. Yarn distortion had a significant effect on the elastic properties and axial tensile strength of the yarn; specifically, the influence of yarn distortion on the transverse elastic modulus and transverse shear modulus of FBCR3DW was severe, whereas only a slight effect occurred with regard to the other elastic constants and unidirectional tensile properties. Thus, the proposed method provides an effective reference for modeling fiber composites with a weave structure.

    A three-dimensional covalent organic framework (COF-505) constructed from helical organic threads, designed to be mutually weaving at regular intervals, has been synthesized by imine condensation reactions of aldehyde functionalized copper(I)-bisphenanthroline tetrafluoroborate, Cu(PDB)2(BF4), and benzidine (BZ). The copper centers are topologically independent of the weaving within the COF structure and serve as templates for bringing the threads into a woven pattern rather than the more commonly observed parallel arrangement. The copper(I) ions can be reversibly removed and added without loss of the COF structure, for which a tenfold increase in elasticity accompanies its demetalation. The threads in COF-505 have many degrees of freedom for enormous deviations to take place between them, throughout the material, without undoing the weaving of the overall structure.

    Full Text Available Due to the poor transfer organization in urban public transport terminal, pedestrian crowd are often forced to weaving in their transfer flow lines. Frequent weaving behaviors not only decrease passengers’ transfer comfort, but may also trigger serious crowd disaster such as trampling. In order to get accurate understanding of the weaving features of pedestrian crowd and analyze the relevant evolution law, researches have been conducted on the basis of field investigation. First, the typical weaving phenomenon were defined and classified, and a microscopic parameters system of pedestrian crowd weaving flow was constructed. The detection and quantification methods of multiple indicator parameters were also given. Then, correlation between different behavioral parameters was analyzed based on the survey data of weaving pedestrian crowd on the stairs of DongZhiMen (DZM hub. The basic characteristics and evolution law of the weaving behaviors were then discussed, and conclusions were drawn.

    Full Text Available Weaving area may be the critical risk place in the subway transfer station. When improving service level of the weaving area, the characteristic of pedestrian weaving behavior should be systemically discussed. This paper described the mechanism of weaving behavior on high density pedestrian which was analyzed by the collection data of controlled experiment. Different weaving behaviors were contrasted due to different volumes in the bidirectional passageway. Video analysis was conducted to extract pedestrian moving behavior and calibrate the movement data with SIMI Motion. Influence of the high density weaving pedestrian was studied based on the statistical results (e.g., velocity, walking distance, and journey time. Furthermore, the quantitative method by speed analysis was announced to discriminate the conflict point. The scopes of weaving area and impact area at different pedestrian volumes were revealed to analyze the pedestrian turning angle. The paper concluded that walking pedestrians are significantly influenced by the weaving conflict and trend to turn the moving direction to avoid the conflict in weaving area; the ratio of stable weaving area and impact area is 2 to 3. The conclusions do provide a method to evaluate the transfer station safety and a facility layout guidance to improve the capacity.

It’s a persuasive metaphor, to imagine writing in terms of the warp and weft of ideas and words, of narrative threads woven together to become a piece of fabric. The idea of history as fabric brings together a whole different set of tropes, not just of weaving, but of the very materiality of fabric. Does the fabric have a nap, or a pattern? Is it cut with the grain, or on the bias? What of its folds, its seams? All these qualities of fabric have application in the interpretation of history, and some of these images are already familiar in historical discourse.

    This paper describes a way to improve the weld quality through suppressing the porosity formation and restraining the growth of columnar grains by using a weaving beam in laser welding. The experimental results show that the N2 porosity of beamweaving laser welding low carbon steel can be remarkably reduced with increasing weaving frequency, and porosity can be eliminated when the weaving amplitude is only 0.5 mm; and the Ar porosity in the weld metal is decreased with increasing weaving frequency and amplitude when the welding speed is higher than 0.5 m/min. The beam-weaving laser welding of ultrafine grained steel has been investigated. The experimental results show that beam-weaving laser welding with appropriate amplitude and frequency can partly restrain the growth of the columnar grain and improve the tensile strength of the weld metal.

    WEAVE is a new wide-field spectroscopy facility proposed for the prime focus of the 4.2m William Herschel Telescope (WHT), placed in La Palma, Canary Islands, Spain. To allow for the compensation of the effects of temperature-induced and gravity-induced image degradation, the WEAVE prime focus assembly will be translated along the telescope optical axis. The assembly comprises the prime focus corrector with integrated ADC, a central mount for the corrector, an instrument rotator and a twin-focal-plane fibre positioner. Translation is accomplished through the use of a set of purpose-built actuators; collectively referred to as the Focus Translation System (FTS), formed by four independently-controlled Focus Translation Units (FTUs), eight vanes connecting the FTUs to a central can, and a central can hosting WEAVE Instrument. Each FTU is capable of providing a maximum stroke of +/-4mm with sufficient, combined force to move the five-tonne assembly with a positional accuracy of +/-20μm at a resolution of 5μm. The coordinated movement of the four FTUs allows +/-3mm WEAVE focus adjustment in the optical axis and +/-0.015° tilt correction in one axis. The control of the FTS is accomplished through a PLC-based subsystem that receives positional demands from the higher-level Instrument Control System. SENER has been responsible for designing, manufacturing and testing the FTS and the equipment required to manipulate and store the FTS together with the instrument. This manuscript describes the final design of the FTS along with the analyses and simulations that were performed, discusses the manufacturing procedures and the results of early verification prior to integration with the telescope. The plans for mounting the whole system on the telescope are also discussed.

  1. Sector-way meta surfaces: the Meta-Weaves

    2013-01-01

    Confluent with the single dimension of time, breach of time-reversal symmetry is usually perceived as a one-dimensional concept. In its ultimate realization--the optical isolator or the one-way guiding device--it allows optical propagation in one direction, say $+z$, and forbids propagation in the opposite direction, $-z$. However, strongly non-reciprocal or one-way nano-scale threads can be used \\emph{to weave meta-surfaces} thus adding dimensions to this concept in a systematic manner. An example of appropriate threads are the recently developed planar one-way particle chains based on the two-type rotation principle. The resulting surfaces--the meta-weaves--posses generalized non-reciprocity such as "sector-way" propagation, and offer new possibilities for controlling the flow of optical signals in thin surfaces. We provide several meta-weave designs, explore the breach of symmetries in the wave-vector space, and study their properties.

    Full Text Available Establishing a control system in a medium-scale weaving mill by using statistical process control techniques was worked on and considered that the control system also would be a model for weaving mills. To determine production parameters and control them according to a definite sampling plan, the loom stoppages were investigated with their reasons and the defects on the fabric were detected during running of looms in process inspection. Therefore three different kinds of cord and a poplin fabric were observed. Analysis of loom-stoppages gives information about problems which are present in yarns, weaving preparation, weaving processes, and particularly indicates yarn quality, weaving machine adjustments and weaving preparation processes. In conclusion of woven fabric quality evaluations it was determined that the rate of defects originated from yarn is rather higher than that of defects originated from weaving preparation/weaving process.

    Textile technologies have recently attracted great attention as potential biofabrication tools for engineering tissue constructs. Using current textile technologies, fibrous structures can be designed and engineered to attain the required properties that are demanded by different tissue engineering applications. Several key parameters such as physiochemical characteristics of fibers, microarchitecture, and mechanical properties of the fabrics play important roles in the effective use of textile technologies in tissue engineering. This review summarizes the current advances in the manufacturing of biofunctional fibers. Different textile methods such as knitting, weaving, and braiding are discussed and their current applications in tissue engineering are highlighted.

  9. Predicting Spacecraft Trajectories by the WeavEncke Method

    Science.gov (United States)

    Weaver, Jonathan K.; Adamo, Daniel R.

    2011-01-01

    A combination of methods is proposed of predicting spacecraft trajectories that possibly include multiple maneuvers and/or perturbing accelerations, with greater speed, accuracy, and repeatability than were heretofore achievable. The combination is denoted the WeavEncke method because it is based on unpublished studies by Jonathan Weaver of the orbit-prediction formulation of the noted astronomer Johann Franz Encke. Weaver evaluated a number of alternatives that arise within that formulation, arriving at an orbit-predicting algorithm optimized for complex trajectory operations. In the WeavEncke method, Encke's method of prediction of perturbed orbits is enhanced by application of modern numerical methods. Among these methods are efficient Kepler s-equation time-of-flight solutions and self-starting numerical integration with time as the independent variable. Self-starting numerical integration satisfies the requirements for accuracy, reproducibility, and efficiency (and, hence, speed). Self-starting numerical integration also supports fully analytic regulation of integration step sizes, thereby further increasing speed while maintaining accuracy.

  10. Flexible Elements in the Mechanisms of Weaving Machines

    Science.gov (United States)

    Žák, J.

    Weaving machines use several mechanisms to produce a fabric; their relative (mutual) position is exactly defined at any point of working cycle and must be maintained as accurately as possible. From that, it results some requirements on their design, such as stiffness of the joint frame, synchronization of their drives, accuracy and stiffness of particular links of those mechanisms and minimization of the clearances between them. In this paper, we have attempted to outline the possibility of replacing the binary links by using the flexible mechanism elements. In this step, we always removed one rotary constraint at least which is necessary when using a binary link, i.e., a rod, pitman or connecting rod. In practice, it means reducing the number of bearings which have a limited service life, require maintenance and when using them we cannot avoid the formation of clearances. In the case of a slay of the CAMEL weaving machine, it was furthermore possible to use the deformation energy to a relief of the drive, its better regulation and an overall reduction of energy consumption. Although this procedure is not subject to the use of special materials, there can be advantageously used fiber composites whose certain features make the design of such mechanisms easy to a great extent.

    2012-01-01

    Bicycles are known to be rich source of kinetic energy, some of which is available for harvesting during speedy and balanced maneuvers by the user. A conventional dynamo attached to the rim can generate a large amount of output power at an expense of extra energy input from the user. However, when applying energy conversion technology to human powered equipments, it is important to minimize the increase in extra muscular activity and to maximize the efficiency of human movements. This study proposes a novel energy harvesting methodology that utilizes lateral oscillation of bicycle frame (weaving) caused by user weight shifting movements in order to increase the pedaling force in uphill riding or during quick speed-up. Based on the 3D motion analysis, we designed and implemented the prototype of an electro-dynamic energy harvester that can be mounted on the bicycle's handlebar to collect energy from the side-to-side movement. The harvester was found to generate substantial electric output power of 6.6 mW from normal road riding. It was able to generate power even during uphill riding which has never been shown with other approaches. Moreover, harvesting of energy from weaving motion seems to increase the economy of cycling by helping efficient usage of human power.

    This paper describes a new method to identify the type of fabric weave by using a neural network classifier. The characteristic parameters of the input layer, derived from fabric image, are composed of the Markov random field character, the difference between the maximum and the minimum of gray level projections in weft and warp directions, the area ratio of the brightness region to the total area in image, the weft and the warp yarn count. The experimental results show that the neural network classifier can effectively classify fabric weave with 98.33% of accuracy, which is helpful in the recognition of fabric weave parameters.

    In weaving mill departments equipped with shuttle looms there exists a high noise level that has a noxious effect on the human organism, a fact which affects a very great number of employees and has negative repercussions on productivity. Measurements were conducted in different weaving mills to determine the noise level as well as the influence of some factors that depend on the type of construction, the type, number and manner of operation of the looms, etc. Solutions for noise reduction were established that were applied experimentally in some weaving mills, and the results obtained are discussed.

If fabric defects can not be detected during garment production, causes separation of the finished product as second quality. In this study, in a weaving mill, raw fabrics were inspected during three weeks for defect detection after weaving operation and results were investigated using statistical methods. Detected fabric defects has been classified and noted on quality control charts. For statistical investigation of number of defects pareto analysis and p control charts were used from statistical process control methods.

    2014-01-01

    The orb-weaving spiders (Orbiculariae) comprise more than 25% of the approximately 44,000 known living spider species and produce a remarkable variety of webs. The wheel-shaped orb web is primitive to this clade, but most Orbiculariae make webs hardly recognizable as orbs. Orb-weavers date at least to the Jurassic. With no evidence for convergence of the orb web, the monophyly of the two typical orb web taxa, the cribellate Deinopoidea and ecribellate Araneoidea, remains problematic, supported only weakly by molecular studies. The sister group of the Orbiculariae also remains elusive. Despite more than 15 years of phylogenetic scrutiny, a fully resolved cladogram of the Orbiculariae families is not yet possible. More comprehensive taxon sampling, comparative morphology, and new molecular markers are required for a better understanding of orb-weaver evolution.

    Full Text Available Clothes which are used as military clothes are different from the other clothes, because they areworn continuously and long time. Heat, humidity and air movements are very important for these clothesbecause these parameters effect the thermophysiological comfort properties of clothes. These clothes mustallow the passage of water vapour from the body of the garment to feel comfortable to wearer. In thisstudy, moisture management properties of different blends of wool/polyester fabrics which are used inwinter military clothes were examined with MMT test device. For this aim, wetting time, absorption rate,spreading speed, accumulative one way transfer index and overall moisture management capacity offabrics, which have different wool/polyester blend ratio and weave pattern, were investigated. Also fabricpattern which are more appropriate for moisture transfer, were determined.

  19. Weaving a Formal Methods Education with Problem-Based Learning

    Science.gov (United States)

    Gibson, J. Paul

    The idea of weaving formal methods through computing (or software engineering) degrees is not a new one. However, there has been little success in developing and implementing such a curriculum. Formal methods continue to be taught as stand-alone modules and students, in general, fail to see how fundamental these methods are to the engineering of software. A major problem is one of motivation — how can the students be expected to enthusiastically embrace a challenging subject when the learning benefits, beyond passing an exam and achieving curriculum credits, are not clear? Problem-based learning has gradually moved from being an innovative pedagogique technique, commonly used to better-motivate students, to being widely adopted in the teaching of many different disciplines, including computer science and software engineering. Our experience shows that a good problem can be re-used throughout a student's academic life. In fact, the best computing problems can be used with children (young and old), undergraduates and postgraduates. In this paper we present a process for weaving formal methods through a University curriculum that is founded on the application of problem-based learning and a library of good software engineering problems, where students learn about formal methods without sitting a traditional formal methods module. The process of constructing good problems and integrating them into the curriculum is shown to be analagous to the process of engineering software. This approach is not intended to replace more traditional formal methods modules: it will better prepare students for such specialised modules and ensure that all students have an understanding and appreciation for formal methods even if they do not go on to specialise in them.

  20. Weaves as an Interconnection Fabric for ASIM's and Nanosatellites

    1995-01-01

    Many of the micromachines under consideration require computer support, indeed, one of the appeals of this technology is the ability to intermix mechanical, optical, analog, and digital devices on the same substrate. The amount of computer power is rarely an issue, the sticking point is the complexity of the software required to make effective use of these devices. Micromachines are the nano-technologist's equivalent of 'golden screws'. In other words, they will be piece parts in larger assemblages. For example, a nano-satellite may be composed of stacked silicon wafers where each wafer contains hundreds to thousands of micromachines, digital controllers, general purpose computers, memories, and high-speed bus interconnects. Comparatively few of these devices will be custom designed, most will be stock parts selected from libraries and catalogs. The novelty will lie in the interconnections. For example, a digital accelerometer may be a component part in an adaptive suspension, a monitoring element embedded in the wrapper of a package, or a portion of the smart skin of a launch vehicle. In each case, this device must inter-operate with other devices and probes for the purposes of command, control, and communication. We propose a software technology called 'weaves' that will permit large collections of micromachines and their attendant computers to freely intercommunicate while preserving modularity, transparency, and flexibility. Weaves are composed of networks of communicating software components. The network, and the components comprising it, may be changed even while the software, and the devices it controls, are executing. This unusual degree of software plasticity permits micromachines to dynamically adapt the software to changing conditions and allows system engineers to rapidly and inexpensively develop special purpose software by assembling stock software components in custom configurations.

    Full Text Available Onychophorans, or velvet worms, are poorly known and rare animals. Here we report the discovery of a new species that is also the largest onychophoran found so far, a 22cm long female from the Caribbean coastal forest of Costa Rica. Specimens were examined with Scanning Electron Microscopy; Peripatus solorzanoi sp. nov., is diagnosed as follows: primary papillae convex and conical with rounded bases, with more than 18 scale ranks. Apical section large, spherical, with a basal diameter of at least 20 ranks. Apical piece with 6-7 scale ranks. Outer blade 1 principal tooth, 1 accessory tooth, 1 vestigial accessory tooth (formula: 1/1/1; inner blade 1 principal tooth, 1 accessory tooth, 1 rudimentary accessory tooth, 9 to 10 denticles (formula: 1/1/1/9-10. Accessory tooth blunt in both blades. Four pads in the fourth and fifth oncopods; 4th. pad arched. The previously unknown mechanism by which onychophorans weave their adhesive is simple: muscular action produces a swinging movement of the adhesive-spelling organs; as a result, the streams cross in mid air, weaving the net. Like all onychophorans, P. solorzanoi is a rare species: active protection of the habitat of the largest onychophoran ever described, is considered urgent. Rev. Biol. Trop. 58 (4: 1127-1142.

    Noise was evaluated in six spinning and five weaving halls located in three textile mills in Egypt. Spindle speed (rpm) and loom speed (picks per minutes) were found to be important parameters affecting the noise level in these mills. Reduction of the number of spinning machines to five spindles per square meter of floor area will probably bring the noise level below the TLV. In the weaving departments, the decrease in the number of looms will not effectively reduce the noise level.

    Kelarai, a design for weaving, which is made up of various motifs can be produced by a variety of natural products. The main focus of the study is on Kelarai Bertam which is selected based on the firm and robust quality of the wood which was often used as the building materials of traditional houses. The objective of the study is to investigate the geometrical design in the weaving art of kelarai bertam, the stimulation of mathematical thoughts in geometrical designs and the evolution of geometrical designs in the weaving art of kelarai bertam. The research method utilized in the study was the triangulation method consisting of observation, interview and analysis. The findings revealed that quadrilateral forms and symmetrical forms such as reflection, translation, rotation and magnification were present in the weaving of kelarai bertam. The design of kelarai has undergone the process of evolution beginning from the Siku Keluang motif and has now expanded to 20 exquisite motifs. The evolution of the design and motifs resulted from the observation made upon the natives' house and wall decorations from Indonesia. In fact, geometrical concept has long been applied in the weaving art but this was not realized by the individual weaver. It is suggested that extensive research can be conducted on the combination of different weaving materials such as wild bertam and bamboo which will produce different geometrical designs such as polygon.

    The objective of this research is to observe weaving problems, analyze the capacity of the weaving segment and to identify the behavior of the Malaysian driver at urban freeway weaving segment. Field data collected during non - peak hours at km. 138.6-138.2 (north bound) Seberang Jaya: Penang Bridge, km.16.8 to km.17.0 Sunway Mentari: Damansara-Puchong Highway and km.21.4 to km.21.9 Puchong Intan: Damansara-Puchong Highway. These segments behave as a bottleneck during peak hour. The data collected are traffic volume, vehicle composition and the road geometry. The drivers behavior pattern at the freeway weaving segment is observed. This research analyses by two different methodologies, the first analysis is by referring to the US Highway Capacity Manual 2010 and the second analysis through a modified method to suit the local traffic composition. The consideration of motorcycle and light heavy vehicle in the analysis lead to a different evaluation of weaving segment capacity. The analysis results show a slight difference between both methods. LOS, weaving speed and density prediction by the modified method is slightly higher than the HCM method. These results, suggest that the numbers of light heavy vehicle and motorcycle contribute to the amount of traffic volume because the value factors of Passenger Car Equivalent (PCE). The adoption of the widely used method without taking consideration of local traffic condition, might lead to improper road planning or design or road operation management.

    Full Text Available Problem statement: Silk cloth weaving culture of the Mon-Khmer ethnic group in Lower-Isan has a specific identity which should be handed down to future generation. The purposes of this research were to examine: (1 the body knowledge concerning silk clothes of the Mon-Khmer ethnic group in Lower-Isan region, (2 the process of production or silk-cloth weaving of the Mon-Khmer ethnic group in Lower-Isan region and (3 development of silk-cloth weaving of the Mon-Khmer ethnic group in Lower-Isan region. Approach: The research data was gathered from documents concerned and research fields. A sample was 156 people living at 7 villages and those involving silk-cloth production or weaving. The data was analyzed according to the research purposes and presented by means of a descriptive analysis. Results: Silk-cloth weaving has been a cultural heritage transferred from ancestors. In 1215 Chow Tang Kwan stated that the Siamese people came there, grew mulberries, raised silkworms and wove silk clothes from that time through learning from generation to generation. The cloth-identity and patterns have been party influenced by their ethnic group together with the way of life in each period. In the past, the main purpose of silk-cloth weaving was for household use. Some of the silk clothes were kept for being supplement to various rituals and Buddhist ceremonies. Thus, it was not necessary for them to have commercial production. Household-labor was still an important-productive factor of sufficient economy and reliant society. For the production process, it has been found that at present the economic and social structures have changed from household-use production to commercial production. There are complete production processes in the type of forming groups and the management system by increasing production competency to obtain both quantity and quality as well as standard prices. There are transmutations into a variety of other products and promotion of

  8. Computational modeling of the electromagnetic characteristics of carbon fiber-reinforced polymer composites with different weave structures

    2014-02-01

    Carbon fiber reinforced polymer composites (CFRPC) are of great interest in the aerospace and automotive industries due to their exceptional mechanical properties. Carbon fibers are typically woven and inter-laced perpendicularly in warps and wefts to form a carbon fabric that can be embedded in a binding matrix. The warps and wefts can be interlaced in different patterns called weaving structures. The primary weaving structures are the plain, twill, and satin weaves, which give different mechanical composite properties. The goal of this work is to computationally investigate the dependence of CFRPC microwave and terahertz electromagnetic characteristics on weave structure. These bands are good candidates for the Nondestructive Evaluation (NDE) of CFRPC since their wavelengths are comparable to the main weave features. 3D full wave electromagnetic simulations of several different weave models have been performed using a finite element (FEM) simulator, which is able to accurately model the complex weave structure. The computational experiments demonstrate that the reflection of electromagnetic waves from CFRPC depend sensitively on weave structure. The reflection spectra calculated in this work can be used to identify the optimal frequencies for the NDE of each weave structure.

    The specific aim of this review is to assess the potential contribution of single photon emitting radiopharmaceutical technologies to new drug development. For each phase of therapeutic drug development, published literature was sought that shows single photon emitters can add value by quantifying pharmacokinetics, visualizing mechanisms of drug action, estimating therapeutic safety indices, or measuring dose-dependent pharmacodynamic effects. Not any published reports were found that describe using nuclear medicine techniques to help manage the progress of a new drug development program. As a consequence, most of the case in favor of weaving single photon imaging into the process had to be built on extrapolations from studies that showed feasibility post hoc. The strongest evidence of potential value was found for drug candidates that hope to influence diseases characterized by cell proliferation or cell death, particularly in the fields of oncology, cardiology, nephrology, and inflammation. Receptor occupancy studies were observed to occasionally offer unique advantages over analogous studies with positron emission tomography (PET). Enough hard data sets were found to justify the costs of using single photon imaging in a variety of new drug development paradigms.

    A method to prevent fiber distortion in textile materials employed in a modified weaving process. In a first embodiment, a tacifier in powder form is applied to the yarn and melted while on the fabric. Cool air is then supplied after the tacifier has melted to expedite the solidification of the tacifier. In a second embodiment, a solution form of a tacifier is used by dissolving the tacifier into a solvent that has a high evaporation rate. The solution is then sprayed onto the fabric or fill yarn as each fill yarn is inserted into a shed of the fabric. A third embodiment applies the tacifier in a liquid form that has not been dissolved in a solvent. That is, the tacifier is melted and is sprayed as a liquid onto the fabric or fill yarn as it is being extracted from a fill yarn spool prior to the fill yarn being inserted into the shed of the fabric. A fourth embodiment employs adhesive yarns contained as an integral part of the warp or fill yarn. Additional tacifier material is not required because a matrix is used as the tacifier. The matrix is then locally melted using heating elements on clamping bars or take-up rollers, is cooled, if necessary, and solidified.

  11. Chemical scaffolding: Molecular weaving and functional group protection

    Siltchenko, Svetlana

    Two new supported scaffolds have been designed and synthesized. The suggested design of scaffold for molecular weaving is based on the interlacing of long chain molecule grafted onto the surface with probe molecule. The long chain 21-N-ethyl docosenamine and its silane derivatives were synthesized and fully characterized. The silane derivatives were grafted onto mica and silica surfaces. The thiocarbamate method was successfully used for even distribution of (+) and (-) charges on the modified surface. It was found that aminoalkylsilanes self-assemble on the mica surface forming monolayer islands of variable size. It was shown that thin layer chromatography in electric field can be used as an interlacing loom for conformational changes in immobilized layer supramolecular entanglement. Seven new zinc complexes with unsubstituted and substituted triazamacrocycles have been prepared and characterized crystallographically. The formation of mixed complexes with ethanolamine has been investigated with potentiometry. It was found that the coordination environment around zinc influences its binding properties. In a tetrahedral coordination environment zinc bound water was found to be acidic and prevents ethanolamine coordination. Ethanolamine coordination to zinc occurs when coordination environment is octahedral. Protonation and stability constants were obtained for several new complexes. Zinc complex of a pentadentate, triazamacrocycle was successfully attached to chloropropyl coated silica gel forming the protective scaffold.

    The topic of natural fiber is one of the most active areas in thermoset composite research today. This paper will focuses on the effect of weave designs on the mechanical behaviour of lamina intraply hybrid composites. Twelve specimens were used and they were made of kenaf fibre and glass fibre as a reinforcement and unsaturated polyester resin as a matrix in various weave designs which were plain, twill, satin, basket, mock leno, and leno weave. Vacuum infusion technique was used due to its superior advantages over hand lay-up. The specimens were produced in two types which were kenaf fibre in warp direction interlace with glass fibre in weft direction (WK-WG) and glass fibre in warp direction interlace with kenaf fibre in weft direction (WG-WK). Various weave designs were found to affect the tensile properties. Glass fibre in warp direction has a greater effect on tensile strength compared to kenaf fibre in warp direction. Mock leno weave exhibited better mechanical properties for WK-WG and WG-WK, about 54.74 MPa and 99.46 MPa respectively.

    This paper focuses on the effect of weaving patterns and orientations on the energy absorption of woven kenaf reinforced polyester composites. Kenaf fiber in the form of yarn is weaved to produce different weaving patterns such as plain, twill and basket. Three woven mats are stacked together and mixed with polyester resin before it is compressed to squeeze out any excessive resin. There is 9 different orientations are used during stacking processes. The hardened composites are cured for 24 hours before it is shaped according to specific dimensions for imp act tests. The composites are perforated with 1m/s blunted projectile. According to the experimental findings, both weaving patterns and orientations have distinct potential effects on the force-displacement diagrams. However, fiber orientations have insignificant effect for plain woven especially in the first stage of deformations. Energy absorption performances for each composite condition are calculated and then plotted against fiber orientations for different weaving patterns. It is found there is no strong relationship between energy absorption and fiber orientations. However for each case of composites, higher energy absorption is found for the composites orientated using [+40°/-15°/+40°/+75°]. Based on the fracture observation, both plain and basket-type woven composites reveal large fragmentations occurred indicating lower energy absorption performances. While for twill condition, no obvious fragmentation is observed where the impact damage around the perforated hole is uniformly distributed leading to higher capability of energy absorptions.

  14. Dynamic Data Visualization with Weave and Brain Choropleths.

    Dianne Patterson

    Full Text Available This article introduces the neuroimaging community to the dynamic visualization workbench, Weave (https://www.oicweave.org/, and a set of enhancements to allow the visualization of brain maps. The enhancements comprise a set of brain choropleths and the ability to display these as stacked slices, accessible with a slider. For the first time, this allows the neuroimaging community to take advantage of the advanced tools already available for exploring geographic data. Our brain choropleths are modeled after widely used geographic maps but this mashup of brain choropleths with extant visualization software fills an important neuroinformatic niche. To date, most neuroinformatic tools have provided online databases and atlases of the brain, but not good ways to display the related data (e.g., behavioral, genetic, medical, etc. The extension of the choropleth to brain maps allows us to leverage general-purpose visualization tools for concurrent exploration of brain images and related data. Related data can be represented as a variety of tables, charts and graphs that are dynamically linked to each other and to the brain choropleths. We demonstrate that the simplified region-based analyses that underlay choropleths can provide insights into neuroimaging data comparable to those achieved by using more conventional methods. In addition, the interactive interface facilitates additional insights by allowing the user to filter, compare, and drill down into the visual representations of the data. This enhanced data visualization capability is useful during the initial phases of data analysis and the resulting visualizations provide a compelling way to publish data as an online supplement to journal articles.

    The nature of the spiral arms of our Milky Way Galaxy is still a matter of debate. Different theories have been suggested (density waves, swing amplification, invariant manifolds...) which impose several constraints on the observables. For the first time it will be possible to disentangle these theories by combining Gaia and WEAVE data. Great advantage comes from the fact that WEAVE is in the Northern Hemisphere, that is with good coverage towards the galactic anticenter. We plan to quantify the kinematic perturbation induced by the Perseus spiral arm through radial velocity measurements. We show how, for the first time, we have detected the stellar overdensity associated with the Perseus arm using a Strömgren photometric survey with the Wide Field Camera on the Isaac Newton Telescope. This survey has allowed us to perform first tests on WEAVE capabilities.

    Full Text Available The warp ikat method of making decorated textiles is one of the most geographically widespread in southeast Asia, being used by Austronesian peoples in Indonesia, Malaysia and the Philippines, and Daic peoples on the Asian mainland. In this study a dataset consisting of the decorative characters of 36 of these warp ikat weaving traditions is investigated using Bayesian and Neighbornet techniques, and the results are used to construct a phylogenetic tree and taxonomy for warp ikat weaving in southeast Asia. The results and analysis show that these diverse traditions have a common ancestor amongst neolithic cultures the Asian mainland, and parallels exist between the patterns of textile weaving descent and linguistic phylogeny for the Austronesian group. Ancestral state analysis is used to reconstruct some of the features of the ancestral weaving tradition. The widely held theory that weaving motifs originated in the late Bronze Age Dong-Son culture is shown to be inconsistent with the data.

    C/Epoxy plain-weave composite is difficult to clear imaging in Micro CT with flat panel detector due to the similar atomic numbers of component materials. To solve this problem, a new Micro CT equipment with high-resolution lens-coupled detector is used to reconstruct 3D images of C/Epoxy. Slice data correction with ellipse projection is used to acquire real yarn normal cross-section information. A reference period method suitable for plain-weave composite is then detailed to evaluate statistical properties of yarn feature parameters. In the process of determination of real extreme slices, dislocation phenomenon existed in the laminated composite is discovered. Several possible reasons caused this phenomenon are discussed. Systematic trends, standard deviations and correlation lengths of stochastic deviations with original and corrected data are evaluated respectively by the application of reference period method. The statistical results show that mean out-of-plane yarn waviness, semi-axes, cross-section area and aspect ratio exhibit periodic characteristics, and the maximum effect of slice data correction on all statistical properties of feature parameters is twist angle.

    2016-10-01

    This paper briefly describes the powerful linkages between the Gaia and PLATO missions and the potential for WEAVE in the study of exoplanet populations, for instance through the proposed WxES survey. Gaia successfully launched in December 2013, and over the course of its nominal five year mission will discover, via their astrometric signatures, upwards of 20 000 massive Jupiter sized long period planets at distances out to several hundred parsecs around all star types. In addition Gaia will discover up to a thousand short period hot Jupiters around M stars. PLATO, to launch in 2024, will through precision photometry, observe in detail some million host stars, and will detect, via the transit technique, planets down to Earth masses. PLATO will observe two fields of over 2 000 square degrees for 2-3 years each. At least one of these will be in the northern hemisphere. WEAVE has the potential to provide detailed chemical characterization of the host stars of the Gaia and PLATO exoplanet systems. This will enable insights into, for instance, metallicity of the host star correlations against both massive exoplanets (perhaps confirming current relationships), and lower mass exoplanets. We note how the rapid exploitation of such a potential WEAVE survey could be achieved, utilizing the WEAVE processing systems being developed at the IoA, Cambridge, coupled with efficient interfaces to both Gaia and PLATO data products, that are also being generated at the IoA.

    Increasing demands for wearable energy sources and highly flexible, lightweight photovoltaic devices have stimulated the development of textile-structured solar cells. However, the former approach of wire-type solar cell fabrication, followed by weaving of these devices, has had limited success, due to device failure caused by high friction forces and tension forces during the weaving process. To overcome this limitation, we present a new approach for textile solar cell fabrication, in which dye-sensitized solar cell (DSSC) electrodes are incorporated into the textile during the weaving process, using the textile warp as a spacer to maintain the DSSC structure. Porous, dye-loaded TiO2-coated holed metal ribbon and Pt nanoparticle-loaded carbon yarn were used as the photoanode and counterelectrode, respectively. The highly flexible textile-based solar cell was fabricated using a common weaving process with a loom. The inserted DSSCs in the textile demonstrated an energy conversion efficiency of 2.63% (at 1 sun, 1.5 A.M.). Our results revealed that additional performance enhancement was possible by considering other electrode materials and textile structures, as well as where and how the DSSC electrodes are inserted. In addition, we demonstrated that the inserted DSSCs could be electrically connected using a parallel configuration. PMID:26087134

    2017-07-05

    Vehicle interior noise functions at the dominant frequencies of 500 Hz below and around 800 Hz, which fall into the bands that may impair hearing. Recent studies demonstrated that freeway commuters are chronically exposed to vehicle interior noise, bearing the risk of hearing impairment. The interior noise evaluation process is mostly conducted in a lab environment. The test results and the developed noise models may underestimate or ignore the noise effects from dynamic traffic, road conditions and configuration. However, the interior noise is highly associated with vehicle maneuvering. The vehicle maneuvering on a freeway weaving segment is more complex for its nature of conflicting areas. This research is intended to explore the risk of the interior noise exposure on freeway weaving segments for freeway commuters, and improve the interior noise estimation by constructing a decision tree learning based noise exposure dose (NED) model, considering weaving segment designs and engine operation. On-road driving tests were conducted to twelve subjects on State Highway 288 in Houston, Texas. An On-board Diagnosis (OBD) II, a smartphone based roughness app, and a digital sound meter were used to collect vehicle maneuvering and engine information, International Roughness Index, and interior noise levels, respectively. Eleven variables were obtainable from the driving tests, including the length and type of a weaving segment, serving as predictors. The importance of the predictors was estimated by their Out-Of-Bag permuted predictor delta errors. The hazardous exposure level of the interior noise on weaving segments is quantified to Hazard Quotient, NED and daily noise exposure level, respectively. Results showed that the risk of hearing impairment on freeway is acceptable, the interior noise level is the most sensitive to the pavement roughness, and subject to freeway configuration and traffic conditions. The constructed NED model performs highly predictive power (R

    Full Text Available Data security is the very important part in the network data communication. Avoidance of the information hacking and steeling are very challenging part for network data communication. Now-a-days people are using many encryption and decryption techniques for data security. But all encryption and decryption techniques are having more time occupation or less security for the process. This paper proposed high level security approach to encryption and decryption for data security. Two levels of securities are used in this proposed method. First one is data encryption and the second one is hash value generation. The proposed Weaving based Superior Encryption Standard (WSES uses a novel weaving based approach. The weaving array generation is done by Elementary Number Theory Notation (ENTN method. The weaving array has multiple private keys for XOR encryption. After encryption the error value is extracted from the encrypted array and weaving array. This error value is sent to the other side. The novel approach for hash value generation uses the encrypted array. After encryption, the encrypted array is rotated into four degrees and each degree data are converted to vector format and arranged on by one under the vector. Finally a 2D Rotational Encryption Matrix (REM is obtained. After this process a REM copy is converted to mirror flip and it is need as Flipped Matrix (FM. The FM is concatenated under the REM and converted to vector using the zigzag operation. Finally this process gives two bytes hash value from the vector. This proposed method executes very fast and provide high security. This method is much reliable to small size applications and also used for any type of data security.

    Full Text Available The Statesman is Plato’s neglected political work, but it is crucial for the understanding of the development of his political thinking as well as extending the understanding of his other works. The dialogue Statesman combines two or even more subjects and different aspects of the same subject; the dialogue likewise contains a central section on paradigm and measure which affects the passage between the statesman as a shepherd and the statesman as a weaver. It is ostensibly an attempt to arrive at the definition of the statesman as a ruler who has political power called for a specialized knowledge.This article analyses the dialogue itself, seeks relation to the other Plato’s writings as well as to old archaic and essential symbols, which are found in many different traditions and represent the text as a web, as a cloth referring to many different layers of the text. Also there is put an emphasis on linguistic and stylistic analysis, which is based on comparison of compounds, terminology, specific terms of weaving as well as some astronomical terms. There is also given a wide comparison of weaving which appears as one of the most essential elements of the text which interweaves all its layers and binds together its philosophical, textological and cultural issues as a continuous unity.

    The development of lamina intraply composite is a novel approach that can be adopted to address the challenges of balance mechanical properties of polymer composite. This research will focuses on the effects of weave designs on the mechanical behavior of a single ply or also known as lamina intraply composite. The six (6) specimens of lamina intraply composites were made by kenaf fiber as a reinforcement and unsaturated polyester resin as a matrix in various weave designs which were plain, twill, satin, basket, mock leno and leno weave. The vacuum infusion technique was adopted due to advantages over hand lay-up. It was found that the plain, twill and satin weave exhibited better mechanical properties on tensile strength. The fiber content of the specimen was 40% and the result of the resin content of the specimen was 60% due to the higher permeability of natural fiber.

    Increasing the stability of a motorcycle requires an understanding of the optimal conditions of the tyre. The inflation pressure is one of the main parameters that directly affects the tyre properties, which in turn influences motorcycle stability and safety. This paper focuses on the effect of the inflation pressure of the tested tyres on motorcycle weave stability. Experimental data are collected from tests carried out in straight running at constant speed. The data analysis is based on stochastic subspace identification methods. Simulations are performed using an advanced motorcycle multi-body code with parameters measured from the tested vehicle. Finally, the comparison between simulations and experimental tests is discussed. The research results show an agreement between experimental tests and simulations where weave stability increases with inflation pressure for the specified range of tyre pressure.

    WEAVE is the next-generation wide-field optical spectroscopy facility for the William Herschel Telescope (WHT) on La Palma in the Canary Islands, Spain. It is a multi-object "pick-and-place" fibre-fed spectrograph with a 1000 fibre multiplex behind a new dedicated 2° prime focus corrector. The WEAVE positioner concept uses two robots working in tandem in order to reconfigure a fully populated field within the expected 1 hour dwell-time for the instrument (a good match between the required exposure times and the limit of validity for a given configuration due to the effects of differential refraction). In this paper we describe some of the final design decisions arising from the prototyping phase of the instrument design and provide an update on the current manufacturing status of the fibre positioner system.

    The project of air-condition measurement and control system based on LabVIEW is put forward for the sake of controlling effectively the environmental targets in the weaving workshop. In this project, which is based on the virtual instrument technology and in which LabVIEW development platform by NI is adopted, the system is constructed on the basis of the virtual instrument technology. It is composed of the upper PC, central control nodes based on CC2530, sensor nodes, sensor modules and executive device. Fuzzy control algorithm is employed to achieve the accuracy control of the temperature and humidity. A user-friendly man-machine interaction interface is designed with virtual instrument technology at the core of the software. It is shown by experiments that the measurement and control system can run stably and reliably and meet the functional requirements for controlling the weaving workshop.

  6. "Lungisa"-weaving relationships and social space to restore health in rural KwaZulu Natal.

    2014-06-01

    Many Zulu people who live in big cities in South Africa return to their rural homestead when they fall ill. Although the health care offered in rural areas is not efficient, people wish to connect to their family and ancestors. My aim is to explore acts of lungisa ("to put in order") and what they say about health, agency, and the circumstances under which people live. Returning home means weaving oneself firmly within a web of relationships that are located in material things and places. Healing involves imperfect strategies used to better connect bodies, relationships, and places. I theorize the acts of returning using Adriana Cavarero's concept of weaving together and argue that people produce space and relationships over time to exert some control over a life lived under political and economic circumstances that have created separation. Six months of ethnographic fieldwork make up the material for my analysis.

    Full Text Available In this research software was designed for assessing the inter-yarn zone fabric porosity of Tencel plain weave fabrics in terms of flow of dye liquor by using Matlab. Fabric images were captured at constant light intensity and magnification using an optical microscope and image analysis software. The captured images were first converted into monochrome image and then into binary image at specific threshold value (150. The percentage of white pixels in the binary image were calculated which assessed the fabric porosity in percentage. The loosely woven fabric gives higher percentage of fabric porosity as compared to the tightly woven fabric. This software has potential to calculate the fabric porosity of plain weave fabric manufactured from any type of raw material.

    Tetraethyl lead (TEL) poisoning has declined sharply with decreasing consumption of gasoil and other chemicals contained TEL. Here we reported group TEL poisoning in the plastic weaving factory. We investigated 16 cases with the typical nerves disorder which is similar to organotin poisoning, and the result suggested that the poisoning may cause by applied "white oil" contented TEL. Despite its rareness, our cases emphasize that clinicians should pay attention to the difference from the treatment of organic tin poisoning.

    Expressions are derived for the displacements of a many storied building subjected to the action of classical weaving looms located at different levels of the building. The building is regarded as a vertical fixed beam with a uniformly distributed mass as well as concentrated masses at each level. The calculation relations are obtained on the assumption of harmonic variation of the forces acting at each level as well as the assumption of narrow band stationary random excitatory forces.

  11. Influence of weave structures on the tribological properties of hybrid Kevlar/PTFE fabric composites

    2012-09-01

    The existing research of the woven fabric self-lubricating liner mainly focus on the tribological performance improvements and the service life raised by changing different fiber type combinations, adding additive modification, and performing fiber surface modification. As fabric composites, the weave structures play an important role in the mechanical and tribological performances of the liners. However, hardly any literature is available on the friction and wear behavior of such composites with different weave structures. In this paper, three weave structures (plain, twill 1/3 and satin 8/5) of hybrid Kevlar/PTFE fabric composites are selected and pin-on-flat linear reciprocating wear studies are done on a CETR tester under different pressures and different frequencies. The relationship between the tensile strength and the wear performance are studied. The morphologies of the worn surfaces under the typical test conditions are analyzed by means of scanning electron microscopy (SEM). The analysis results show that at 10 MPa, satin 8/5 performs the best in friction-reduction and antiwear performance, and plain is the worst. At 30 MPa, however, the antiwear performance is reversed and satin 8/5 does not even complete the 2 h wear test at 16 Hz. There is no clear evidence proving that the tensile strength has an influence on the wear performance. So the different tribological performance of the three weave structures of fabric composites may be attributed to the different PTFE proportions in the fabric surface and the different wear mechanisms. The fabric composites are divided into three regions: the lubrication region, the reinforced region and the bonding region. The major mechanisms are fatigue wear and the shear effects of the friction force in the lubrication region. In the reinforced region fiber-matrix de-bonding and fiber breakage are involved. The proposed research proposes a regional wear model and further indicates the wear process and the wear mechanism

    In these proceedings we describe the WEAVE-QSO survey, which will observe around 400,000 high redshift quasars starting in 2018. This survey is part of a broader WEAVE survey to be conducted at the 4.2m William Herschel Telescope. We will focus on chiefly on the science goals, but will also briefly summarise the target selection methods anticipated and the expected survey plan. Understanding the apparent acceleration in the expansion of the Universe is one of the key scientific challenges of our time. Many experiments have been proposed to study this expansion, using a variety of techniques. Here we describe a survey that can measure this acceleration and therefore help elucidate the nature of dark energy: a survey of the Lyα forest (and quasar absorption in general) in spectra towards z>2 quasars (QSOs). Further constraints on neutrino masses and warm dark matter are also anticipated. The same data will also shed light on galaxy formation via study of the properties of inflowing/outflowing gas associated with nearby galaxies and in a cosmic web context. Gas properties are sensitive to density, temperature, UV radiation, metallicity and abundance pattern, and so constraint galaxy formation in a variety of ways. WEAVE-QSO will study absorbers with a dynamic range spanning more than 8 orders of magnitude in column density, their thermal broadening, and a host of elements and ionization species. A core principal of the WEAVE-QSO survey is the targeting of QSOs with near 100% efficiency principally through use of the J-PAS (r < 23.2) and Gaia (r ≲ 20) data.

    Full Text Available The tear strength of a woven fabric is very important, since it is more closely related to serviceability of the fabric. Tearing strength of the fabrics depend on the mobility of the yarn within the fabric structure. In this study, the tearing strength of four types of fabrics warp rib, weft rib, ripstop and plain weave were analysed, which were produced in different densities and with filament and texturised polyester yarns.

    Insects of the heteropteran families Pentatomidae (stink bugs) and Coreidae (squash bugs), when being eaten by the orb-weaving spider Nephila clavipes, attract flies of the family Milichiidae. The flies aggregate on the bugs and, as kleptoparasites, share in the spider's meal. Stink bugs and squash bugs typically eject defensive sprays when attacked; they do so when caught by Nephila, but the spray only minimally affects the spider. Evidence is presented indicating that it is the spray of the...

  15. Tune and Textile: Interrelatedness in the Music and Weaving Arts of the T’boli, Philippines

    Directory of Open Access Journals (Sweden)

    Manolete Mora

    2012-12-01

    Full Text Available This article seeks to explicate the key concept for music called utom of the T’boli of Mindanao (Philippines by way of analogy with T’boli design (b’teken as found in their renowned t’nalak textiles. In so doing, basic aesthetic principles that are shared between the two different artistic domains are uncovered. My argument is that fundamental principles of T’boli weaving design are analogous with concepts of instrumental composition. In this context, the use of analogy to explain aspects of one artistic domain in terms of another is apposite because it resonates with the extensive use of analogy and metaphor within the cultural and social life of the T’boli. Moreover, as we shall see, the basic concepts and elements of weaving design are remarkably similar to those of musical composition. An understanding of the translatability between the two artistic domains, weaving and music, came from particular dialogues and interactions between the T’boli and myself during fieldwork. At the same time, it was also stimulated by a predisposition toward certain artistic and intellectual orientations in my own ‘‘Western’’ culture, specifically, those that embrace intermodal, intermedial, intertextual, and synaesthesic approaches and which, at a general level, resonate with T’boli practices that extend the meanings of words and concepts from one cultural domain to another.

  16. Simulation of Complex Cracking in Plain Weave C/SiC Composite under Biaxial Loading

    Cheng, Ron-Bin; Hsu, Su-Yuen

    2012-01-01

    Finite element analysis is performed on a mesh, based on computed geometry of a plain weave C/SiC composite with assumed internal stacking, to reveal the pattern of internal damage due to biaxial normal cyclic loading. The simulation encompasses intertow matrix cracking, matrix cracking inside the tows, and separation at the tow-intertow matrix and tow-tow interfaces. All these dissipative behaviors are represented by traction-separation cohesive laws. Not aimed at quantitatively predicting the overall stress-strain relation, the simulation, however, does not take the actual process of fiber debonding into account. The fiber tows are represented by a simple rule-of-mixture model where the reinforcing phase is a hypothetical one-dimensional material. Numerical results indicate that for the plain weave C/SiC composite, 1) matrix-crack initiation sites are primarily determined by large intertow matrix voids and interlayer tow-tow contacts, 2) the pattern of internal damage strongly depends on the loading path and initial stress, 3) compressive loading inflicts virtually no damage evolution. KEY WORDS: ceramic matrix composite, plain weave, cohesive model, brittle failure, smeared crack model, progressive damage, meso-mechanical analysis, finite element.

    2010-01-01

    The Iberá Marshlands RAMSAR reserve, in the northeast of Argentina, is one of the largest and most important wetlands of America. In this study we assess orb-weaving spider (Araneae: Orbiculariae) diversity in this reserve, analyzing different facets of local diversity (species richness, diversity, evenness and taxonomic distinctness), and the contribution of species differentiation (beta diversity) among localities and habitat types to the composition of regional diversity. We found 1657 individuals of 59 orb-weaving spider species/morphospecies. Local diversity differs among the three sampled localities. At the habitat level, the different facets of biodiversity followed a clear pattern, where woodlands have higher species richness, diversity, evenness and taxonomic distinctness than savannas. Savanna sites shared a common spider species composition, while woodland communities have high values of complementarity. Thus, beta diversity has a very high contribution to the regional diversity of the orb-weaving spiders in the Iberá Marshlands. We suggest that conservation management in the reserve should be directed towards promoting natural spatial heterogeneity, giving special protection to habitat mosaics in different localities.

    2009-12-01

    Native grasslands are among the most imperiled of the North American ecosystems, but abandoned agricultural areas may provide suitable habitat for animal taxa that are endemic to grasslands. We studied how species diversity of orb-weaving spiders was influenced by secondary succession of a grassland plant community by monitoring the abundance and species diversity in study plots that were cultivated at 6-yr intervals and left uncultivated in the interim. We tested the hypothesis that local abundance and species diversity of spiders would be positively associated with time since cultivation because plant communities in older habitats would be more architecturally complex. Local abundance of spiders in general was not associated with time since cultivation, but abundance of Mangora gibberosa (Hentz) was positively associated with the abundance of perennial plants. Species richness and diversity of spiders also were positively associated with the abundance of perennial plants and reached a threshold a few years after cultivation. Species diversity of orb-weaving spiders seems to be strongly influenced by species composition of the plant community. Therefore, effective restoration of the structure and function of endemic communities of orb-weaving spiders may depend on preserving endemic grassland plant communities.

    Allometric studies of the gross neuroanatomy of adults from nine species of spiders from six web-weaving families (Orbicularia), and nymphs from six of these species, show that very small spiders resemble other small animals in having disproportionately larger central nervous systems (CNSs) relative to body mass when compared with large-bodied forms. Small spiderlings and minute adult spiders have similar relative CNS volumes. The relatively large CNS of a very small spider occupies up to 78% of the cephalothorax volume. The CNSs of very small spiders extend into their coxae, occupying as much as 26% of the profile area of the coxae of an Anapisona simoni spiderling (body mass spiders also have reduced neuronal cell body diameters. The adults of nearly all orbicularian spiders weave prey capture webs, as do the spiderlings, beginning with second instar nymphs. Comparable allometric relations occur in adults of both orb-weaving and cleptoparasitic species, indicating that this behavioral difference is not reflected in differences in gross CNS allometry.

  1. Application of Geospatial Information System for the Study of Illuminance in Carpet Weaving Workshops in Bokan, Iran

    Directory of Open Access Journals (Sweden)

    Faramarz Madjidi

    2015-12-01

    Full Text Available Background: Carpet weaving is an occupation that requires sufficient and appropriate lighting. The lighting in carpet weaving workshops affects the productivity and the physical and mental health of workers. Therefore, the evaluation of the illumination and the identification of work stations requiring lighting modifications will be helpful in promotion of the health and safety of workers in carpet weaving workshops. Methods: This study was carried out for the evaluation of illumination on the basis of Geospatial Information System (GIS technology in two carpet weaving workshops of Bokan city. As per the norms of Illumination Engineering Society, the sensors of the photometer Testo 545 were placed at lowest and highest of 35 and 163 cm in workshop I, and at 40 and 245 cm in workshop II, which correspond to the lowest and highest work surfaces in the respective workshops. Total, natural, and artificial illuminance was measured in the center of each measurement station using the photometer, and data was analyzed using the Arc GIS software. The maximum and minimum illuminances as well as isolux curves were obtained for each workshop. Results: The illuminance in workshops I and II were found to be lower and higher, respectively, than 200 lux, which is considered the standard for carpet weaving workshops. Thus, improving the artificial lighting system or redesigning it is essential for ensuring that the standard conditions of illuminance (200–300 lux are provided. Discussion: This study showed that the application of GIS technology renders the assessment of illumination in carpet weaving workshops possible. This assessment method could also prove useful for determining the exact stations in the carpet weaving workshops that need modifications, thereby leading to cost reduction.

  2. Damping capacity is evolutionarily conserved in the radial silk of orb-weaving spiders.

    Kelly, Sean P; Sensenig, Andrew; Lorentz, Kimberly A; Blackledge, Todd A

    2011-09-01

    Orb-weaving spiders depend upon their two-dimensional silk traps to stop insects in mid flight. While the silks used to construct orb webs must be extremely tough to absorb the tremendous kinetic energy of insect prey, webs must also minimize the return of that energy to prey to prevent insects from bouncing out of oscillating webs. We therefore predict that the damping capacity of major ampullate spider silk, which forms the supporting frames and radial threads of orb webs, should be evolutionarily conserved among orb-weaving spiders. We test this prediction by comparing silk from six diverse species of orb spiders. Silk was taken directly from the radii of orb webs and a Nano Bionix test system was used either to sequentially extend the silk to 25% strain in 5% increments while relaxing it fully between each cycle, or to pull virgin silk samples to 15% strain. Damping capacity was then calculated as the percent difference in loading and unloading energies. Damping capacity increased after yield for all species and typically ranged from 40 to 50% within each cycle for sequentially pulled silk and from 50 to 70% for virgin samples. Lower damping at smaller strains may allow orb webs to withstand minor perturbations from wind and small prey while still retaining the ability to capture large insects. The similarity in damping capacity of silk from the radii spun by diverse spiders highlights the importance of energy absorption by silk for orb-weaving spiders. Copyright © 2011 Elsevier GmbH.

    Full Text Available The paper investigates the effects of weave structure and fabric thread density on the comfort and mechanical properties of various test fabrics woven from polyester/cotton yarns. Three different weave structures, that is, 1/1 plain, 2/1 twill and 3/1 twill, and three different fabric densities were taken as input variables whereas air permeability, overall moisture management capacity, tensile strength and tear strength of fabrics were taken as response variables and a comparison is made of the effect of weave structure and fabric density on the response variables. The results of fabric samples were analysed in Minitab statistical software. The coefficients of determinations (R-sq values of the regression equations show a good predictive ability of the developed statistical models. The findings of the study may be helpful in deciding appropriate manufacturing specifications of woven fabrics to attain specific comfort and mechanical properties.

    This case study sought to understand the meaning of restoring traditional weaving as an occupation among Karen women from Burma who now live in an urban city in the United States and to examine the impact of weaving on their daily lives in terms of identity, empowerment, social support, and opportunities for entrepreneurship. The story of one Karen woman, Paw Law Eh, is described. Her story exemplifies the negative consequences of restricted access to familiar and meaningful daily activities, or "occupations", the relationship between occupation and self-identity, how participation in valued occupations can enhance social networks, and the restorative effects that are possible when engagement in meaningful occupations are maintained or restored. Her story demonstrates that occupational therapists have the skills and opportunity to contribute significantly to the well-being of Karen women by supporting the restoration of the occupation of weaving.

    Full Text Available In this paper, energy consumption of the griffes during their serving life is reported. Griffes of the Jacquard loom with reciprocating motion and high speed are the main suffering components during the weaving process. Under the condition of high reciprocating velocity, the mechanical damage is an unavoidable issue that will lead to a fatal collapse on the mechanical parts and even operators. Therefore, finite element analysis is adopted and conducted in present research to intuitively demonstrate the energy consumption on the griffes. This will be benefit for the design and local reinforcement of the Jacquard.

    1993-01-01

    The performance of interlinked, multi-layer fabrics and near net shape preforms for engineering applications, woven on a 48 shaft dobby loom using glass, aramid, and carbon continuous filament yarns is assessed. The interlinking was formed using the warp yarns. Two basic types of structure were used. The first used a single warp beam and hence each of the warp yarns followed a similar path to form four layer interlinked reinforcements and preforms. In the second two warp beams were used, one for the interlinking yarns which pass from the top to the bottom layer through-the-thickness of the fabric and vice versa, and the other to provide 'straight' yarns in the body of the structure to carry the axial loading. Fabrics up to 15mm in thickness were constructed with varying amounts of through-the-thickness reinforcement. Tapered T and I sections were also woven, with the shaping produced by progressive removal of ends during construction. These fabrics and preforms were impregnated with resin and cured to form composite samples for testing. Using these two basic types of construction, the influence of reinforcement construction and the proportion and type of interlinking yarn on the performance of the composite was assessed.

  8. Wealhtheow’s Peace-Weaving: Diegesis and Genealogy of Gender in Beowulf

    Directory of Open Access Journals (Sweden)

    Olesiejko Jacek

    2014-03-01

    Full Text Available This article uses Charles S. Peirce’s concept of icon and Judith Butler’s idea of genealogy of gender to study levels of fictionality in the Old English poem Beowulf. It shows that Wealhtheow, the principal female character in the epic, operates as a diegetic reader in the poem. Her speeches, in which she addresses her husband King Hrothgar and Beowulf contain implicit references to the Lay of Finn, which has been sung by Hrothgar’s minstrel at the feast celebrating Beowulf’s victory. It is argued here that Wealhtheow represents herself as an icon of peace-weaving, as she casts herself as a figuration of Hildeburh, the female protagonist of the Lay of Finn. Hildeburh is the sister of Hnæf, the leader of the Danes, and is given by her brother to Finn the Frisian in a marriage alliance. In her role as a peace-weaver, the queen is to weave peace between tribes by giving birth to heirs of the crown. After the courtly minster’s performance of the Lay, Wealhtheow warns her husband against establishing political alliances with the foreigner Beowulf at the expense of his intratribal obligation to his cousin Hrothulf, who is to become king after Hrothgar’s death.

    We are literally the stuff from which our tissue fabrics and their fibers are woven and spun. The arrangement of collagen, elastin and other structural proteins in space and time embodies our tissues and organs with amazing resilience and multifunctional smart properties. For example, the periosteum, a soft tissue sleeve that envelops all nonarticular bony surfaces of the body, comprises an inherently “smart” material that gives hard bones added strength under high impact loads. Yet a paucity of scalable bottom-up approaches stymies the harnessing of smart tissues’ biological, mechanical and organizational detail to create advanced functional materials. Here, a novel approach is established to scale up the multidimensional fiber patterns of natural soft tissue weaves for rapid prototyping of advanced functional materials. First second harmonic generation and two-photon excitation microscopy is used to map the microscopic three-dimensional (3D) alignment, composition and distribution of the collagen and elastin fibers of periosteum, the soft tissue sheath bounding all nonarticular bone surfaces in our bodies. Then, using engineering rendering software to scale up this natural tissue fabric, as well as multidimensional weaving algorithms, macroscopic tissue prototypes are created using a computer-controlled jacquard loom. The capacity to prototype scaled up architectures of natural fabrics provides a new avenue to create advanced functional materials.

    Achilles tendon rupture is a common injury, especially in those who are physically active. Although open surgery is a widely used option for the treatment of acute Achilles tendon rupture, the optimal treatment is still disputed. In our study, 59 patients with unilateral, closed, acute rupture of the Achilles tendon were treated by open surgery using an allograft weave to augment the repair. All the surgeries were performed within 1 to 4 days after injury. The mean American Orthopaedic Foot and Ankle Society ankle-hindfoot score was recorded as 91.20 (range 88 to 95), 95.34 (range 92 to 98), and 98.27 (range 97 to 99) at the 3-, 6-, and 12-month follow-up visit, respectively. At the final follow-up visit, the mean difference between the mid-calf circumference of the injured and uninjured legs was 0.19 (range -0.03 to 1.50) cm (p = .43). At the final follow-up visit, the mean difference between the vertical distances from the plantar surface of the heel to the ground for the injured and uninjured lower extremities was 0.44 (range -0.03 to 0.5) cm (p = .17). Augmented repair using the allograft tendon weaving technique provided satisfactory tendon strength and functional outcomes and a timely return to the patients' activities.

    Full Text Available Background: The present study aimed to evaluate the biomechanical exposure to the trapezius muscle activity in female weavers for a prolonged period in the workstation A (suggested by previous studies and workstation B (proposed by the present study. Methods: Electromyography data were collected from nine females during four hours for each ergonomically designed workstation at the Ergonomics Laboratory, Hamadan, Iran. The design criteria for ergonomically designed workstations were: 1 weaving height (20 and 3 cm above elbow height for workstations A and B, respectively, and 2 seat type (10° and 0° forwardsloping seat for workstations A and B, respectively. Results: The amplitude probability distribution function (APDF analysis showed that the left and right upper trapezius muscle activity was almost similar at each workstation. Trapezius muscle activity in the workstation A was significantly greater than workstations B (P<0.001. Conclusion: In general, use of workstation B leads to significantly reduced muscle activity levels in the upper trapezius as compared to workstation A in weavers. Despite the positive impact of workstation B in reducing trapezius muscle activity, it seems that constrained postures of the upper arm during weaving may be associated with musculoskeletal symptoms.

    A three-dimensionally integrated microstrip antenna (3DIMA) is a microstrip antenna woven into the three-dimensional woven composite for load bearing while functioning as an antenna. In this study, the effect of weaving direction of conductive yarns on electromagnetic performance of 3DIMAs are investigated by designing, simulating and experimental testing of two microstrip antennas with different weaving directions of conductive yarns: one has the conductive yarns along the antenna feeding direction (3DIMA-Exp1) and the other has the conductive yarns perpendicular the antenna feeding direction (3DIMA-Exp2). The measured voltage standing wave ratio (VSWR) of 3DIMA-Exp1 was 1.4 at the resonant frequencies of 1.39 GHz; while that of 3DIMA-Exp2 was 1.2 at the resonant frequencies of 1.35 GHz. In addition, the measured radiation pattern of the 3DIMA-Exp1 has smaller back lobe and higher gain value than those of the 3DIMA-Exp2. This result indicates that the waving direction of conductive yarns may have a significant impact on electromagnetic performance of textile structural antennas.

    In these proceedings we describe the WEAVE-QSO survey, which will observe around 400,000 high redshift quasars starting in 2018. This survey is part of a broader WEAVE survey to be conducted at the 4.2m William Herschel Telescope. We will focus on chiefly on the science goals, but will also briefly summarise the target selection methods anticipated and the expected survey plan. Understanding the apparent acceleration in the expansion of the Universe is one of the key scientific challenges of our time. Many experiments have been proposed to study this expansion, using a variety of techniques. Here we describe a survey that can measure this acceleration and therefore help elucidate the nature of dark energy: a survey of the Lyman-alpha forest (and quasar absorption in general) in spectra towards z>2 quasars (QSOs). Further constraints on neutrino masses and warm dark matter are also anticipated. The same data will also shed light on galaxy formation via study of the properties of inflowing/outflowing gas associ...

    Many orb-weaving spiders in the tropics forage in open sites during the day and some of them have both bright and dark colourations. The conspicuous UV-reflective colour markings of these spiders have been reported to be attractive to visually oriented prey and thus could increase the spiders' foraging success. Using a combination of field and laboratory studies, we examine whether or not the body colouration of orb-weaving spiders exhibits optical properties that are attractive to insect prey from the viewpoint of insect visual physiology. We compared the prey interception rates and colour contrasts of the typical and melanic morphs of the giant wood spider, Nephila pilipes. Results of the field study showed that the typical morph caught significantly more insects than the melanic morph. Colour contrasts calculated from spectral reflectances of the background and body surface of spiders showed that the brightly coloured body parts of the typical morph exhibited rather high values, but those of the dark body parts were below the discrimination threshold. The differential colour contrasts of body parts generated a visual signal unlike that of a spider but rather like certain forms of food resources. On the other hand, the melanic morphs did not have bright colouration and the colour contrasts of every part of the body were significantly higher than the threshold, making the contour of spiders quite clear to bees.

    Based on IFS, a designing method of irregular and unlimited fractal weaves is studied, for the fractal weave drawing based on L-system has some limitations. With VC + + , the method takes irregular and large cycling basic weaves as the object for application, uses Kronecker product to perform iterative operation of its weave matrix and fast generates fractal weaves of this basic weave. On this basis, using self-similar structure which has multilevel fractal weave, a new design way of fabric weaves is explored, and from it, some special fabrics with complex weave construction and various styles can be generated by selecting different coordinated weaves to fill fractal weaves. The practice has proven that the fabrics designed using this fractal weaves are characterized by more complex weaves that are difficult to be imitated.%针对L系统在绘制织物分形组织图方面存在的局限,基于IFS的生成规则,研究不受任何基本组织形式限制的非规则分形组织设计方法.该方法以非规则、大循环的基本组织为应用对象,运用VC++编程,利用Kronecker叉积进行组织矩阵的迭代运算,快捷地生成此类基本组织的分形组织图.在此基础上,利用分形组织自相似结构所具有的多级层次关系,通过选择不同的填充组织,设计形成结构复杂、风格多变的分形织物.通过织造实验证明,此分形组织设计方法形成的织物纹理效果具有复杂性强,不易模仿等特点.

    2010-12-01

    Full Text Available Onychophorans, or velvet worms, are poorly known and rare animals. Here we report the discovery of a new species that is also the largest onychophoran found so far, a 22cm long female from the Caribbean coastal forest of Costa Rica. Specimens were examined with Scanning Electron Microscopy; Peripatus solorzanoi sp. nov., is diagnosed as follows: primary papillae convex and conical with rounded bases, with more than 18 scale ranks. Apical section large, spherical, with a basal diameter of at least 20 ranks. Apical piece with 6-7 scale ranks. Outer blade 1 principal tooth, 1 accessory tooth, 1 vestigial accessory tooth (formula: 1/1/1; inner blade 1 principal tooth, 1 accessory tooth, 1 rudimentary accessory tooth, 9 to 10 denticles (formula: 1/1/1/9-10. Accessory tooth blunt in both blades. Four pads in the fourth and fifth oncopods; 4th. pad arched. The previously unknown mechanism by which onychophorans weave their adhesive is simple: muscular action produces a swinging movement of the adhesive-spelling organs; as a result, the streams cross in mid air, weaving the net. Like all onychophorans, P. solorzanoi is a rare species: active protection of the habitat of the largest onychophoran ever described, is considered urgent. Rev. Biol. Trop. 58 (4: 1127-1142.

Fibrous sensors previously developed in our laboratory, based on PEDOT:PSS, have been adapted so as to directly measure the mechanical stress on fabrics under static or dynamic conditions. The objective of our research has been to develop new sensor yarns, with the ability to locally detect mechanical stresses all along the warp or weft yarn. This local detection is undertaken inside the weaving loom in real time during the weaving process. Suitable electronic devices have been designed in order to record in situ measurements delivered by this new fibrous sensor yarn.

    Orb-weaving spiders produce bioadhesives that are used to capture their prey. In this paper, the physical properties of these adhesives are characterised. The liquid adhesive from Argiope argentata spiders has been studied and the morphological properties of the droplets, including size, shape and volume were determined. An estimation of viscosity and Young's modulus using atomic force microscopy has also been carried out. Morphological characterization confirmed that the liquid adhesive displayed a typical beads-on-a-string (BOAS) morphology on the silk fibres. The experimental data confirmed that the elastic modulus of the liquid adhesive from A. argentata was in the range 20-100kPa which is in agreement with the Dahlquist criterion for adhesives.

    WEAVE is a 1000-fiber multi-object spectroscopic facility for the 4.2 m William Herschel Telescope. It will feature a double-headed pick-and-place fiber positioning robot comprising commercially available robotic axes. This paper presents results on the performance of these axes, obtained by testing a prototype system in the laboratory. Positioning accuracy is found to be better than the manufacturer's published values for the tested cases, indicating that the requirement for a maximum positioning error of 8.0 microns is achievable. Field reconfiguration times well within the planned 60 minute observation window are shown to be likely when individual axis movements are combined in an efficient way.

  13. Loss of legs: is it or not a handicap for an orb-weaving spider?

    Science.gov (United States)

    Pasquet, Alain; Anotaux, Mylène; Leborgne, Raymond

    2011-07-01

    Leg loss is a common phenomenon in spiders, and according to the species 5% to 40% of the adults can present at least one missing leg. There is no possibility of regeneration after adult moult and the animal must manage with its missing appendages until its death. With the loss of one or more legs, female orb-weaving spiders can be penalized twice: firstly, because the legs are necessary for web construction and secondly, the legs are essential for the control of the prey after its interception by the web. During development, spiders may be also penalized because regeneration has energetic costs that take away resources for survival, growth and reproduction. All these consequences should influence negatively the development of the spider and thus its fitness. We investigated the impact of leg loss in the orb-weaving spider, Zygiella x-notata by studying its frequency in a natural population and web building and prey capture behaviours in laboratory. In field populations, 9.5% to 13%, of the adult females presented the loss of one or more legs; the majority of individuals had lost only one leg (in 48% of cases, a first one). Leg loss seems to affect all the adult spiders, as there is no difference of mass between intact spiders and those with missing leg. Data obtained with laboratory-reared spiders, showed that the loss of legs due to the moult is rare (less than 1%). Considering changes in web design, spiders with missing legs decreased their silk investment, increased the distance between spiral turns but did not change the capture surface of the web. Under our laboratory experimental conditions, spiders with one or two lost legs did not present any difference in prey capture efficiency. In laboratory conditions, spiders with lost leg(s) did not show any difference in egg sac production or in longevity (adult lifespan) compared to intact spiders.

    In this study, woven gas diffusion layers (GDLs) with varying weave type and tightness are investigated. Plain and twill weave patterns were manufactured in-house. The in-plane and through-plane air permeability of the woven samples were tested, and mercury intrusion porosimetry (MIP) tests were performed to study the pore structure. It was found that the twill weave has a higher permeability than the plain weave, which is consistent with literature. Like non-woven carbon papers, woven GDLs have higher in-plane permeability than through-plane permeability; however it has been shown that it is possible to manufacture a GDL with higher through-plane permeability than in-plane permeability. It was also concluded that the percentage of macropores in the weave is the driving factor in determining the through-plane air permeability. This work lays the groundwork for future studies to attempt to characterize the relationship between the weave structure and the air permeability in woven GDLs. (author)

    For Al 6k21-T4 overlap weld joint, the shear-tensile strength by using the weaving laser was improved as compared to the case of linear laser. For the specimen of low strength, the porosity was distributed continuously along the intersection between the plates and fusion line. However, for the optimized welding condition, large oval-shaped porosities were located only in the advancing track of the concave part. Therefore, the continuity of cracks and porosities played a key role to determine the strength. And, the weaving width was also the important parameter to control the strength. Furthermore, the concave part had more significant hot and cold cracking in the weld and heat-affected zone (HAZ), respectively, than the convex part.

  4. Effect of pad location relative to glass weave on cratering and underfill process improvement and material evaluation

    Science.gov (United States)

    Quran, Mohammad M.

    This research contains two studies. First study investigated one of the factors that affect the performance of pads; the locations of pads relative to glass weave. Dage 4000plus bond tester was used in conducting a joint-level testing of pads on 370HR printed circuit board that has 1080 glass fabric. Scanning acoustic microscopy (SAM) was utilized to image pads with respect to upper layer of glass weave. It was found that locations of pads do not affect their strength, but it has a weak effect on fatigue performance. The second part of this research is underfill process improvement and material selection. This study evaluated four underfill materials against a flow model. Assemblies were made of transparent glass slides and then underfilled. Different factors that affect this flow were investigated: substrate temperature, standoff, and material age. In addition, the materials' tendency to form voids during flow or curing was observed.

    2016-06-01

    Multi-scale models play an important role in capturing the nonlinear response of woven carbon fiber reinforced ceramic matrix composites. In plain weave carbon fiber/silicon carbon (C/SiC) composites, the carbon fibers and interphases will be oxidized at elevated temperature and the strength of the composite will be degraded when oxygen enters micro-cracks formed in the as-produced parts due to the mismatch in thermal properties between constituents. As a result of the oxidation on fiber surface, fiber shows a notch-like morphology. In this paper, the change rule of fiber notch depth is fitted by circular function. And a multi-scale model based upon the change rule of fiber notch depth is developed to simulate the residual strength and post-oxidation stress-strain curves of the composite. The multi-scale model is able to accurately predict the residual strength and post-oxidation stress-strain curves of the composite. Besides, the simulated residual strength and post-oxidation stress-strain curves of 2D plain weave C/SiC composites in oxidation atmosphere show good agreements with experimental results. Furthermore, the oxidation time and temperature of the composite are investigated to show their influences upon the residual strength and post-oxidation stress-strain curves of plain weave C/SiC composites.

    Carpet weaving among children is common in rural Pakistan, but little information is available on the health effects of this work. A total of 628 carpet-weaving children and 292 non-working children from 10 rural villages were evaluated with questionnaires and physical exams. Fifty-five home-based and 30 shed-based worksites in these villages were assessed. Girls comprised the majority of working (73%) and non-working (69%) children; the mean age for both boys and girls was 10 years. The mean number of hours worked daily was 7.2 for males and 6.8 for females. Dust exposure in homes was generally higher than in sheds. Working children had significantly greater odds of joint pain (OR = 2.8), dry cough (OR = 2.5), cuts/bruises (OR = 22.1), Phalen's sign (OR = 17.2), and neck/shoulder abnormalities (OR = 14.2). Symptoms and signs of acute and repetitive injury and respiratory symptoms were more common among carpet-weaving children than their non-working peers.

    Ordered ZnO nanosheet arrays were grown on weaved titanium wires by a low-temperature hydrothermal method. CdS nanoparticles were deposited onto the ZnO nanosheet arrays using the successive ionic layer adsorption and reaction method to make a photoanode. Nanoparticle-sensitized solar cells were assembled using these CdS/ZnO nanostructured photoanodes, and their photovoltaic performance was studied systematically. The best light-to-electricity conversion efficiency was obtained to be 2.17% under 100 mW/cm2 illumination, and a remarkable short-circuit photocurrent density of approximately 20.1 mA/cm2 was recorded, which could attribute to the relatively direct pathways for transportation of electrons provided by ZnO nanosheet arrays as well as the direct contact between ZnO and weaved titanium wires. These results indicate that CdS/ZnO nanostructures on weaved titanium wires would open a novel possibility for applications of low-cost solar cells.

    Full Text Available Abstract Background Intimate partner abuse (IPA is a major public health problem with serious implications for the physical and psychosocial wellbeing of women, particularly women of child-bearing age. It is a common, hidden problem in general practice and has been under-researched in this setting. Opportunities for early intervention and support in primary care need to be investigated given the frequency of contact women have with general practice. Despite the high prevalence and health consequences of abuse, there is insufficient evidence for screening in primary care settings. Furthermore, there is little rigorous evidence to guide general practitioners (GPs in responding to women identified as experiencing partner abuse. This paper describes the design of a trial of a general practice-based intervention consisting of screening for fear of partner with feedback to GPs, training for GPs, brief counselling for women and minimal practice organisational change. It examines the effect on women's quality of life, mental health and safety behaviours. Methods/Design weave is a cluster randomised controlled trial involving 40 general practices in Victoria, Australia. Approximately 500 women (16-50 years seen by the GP in the previous year are mailed a short lifestyle survey containing an item to screen for IPA. Women who indicate that they were afraid of a partner/ex-partner in the last year and provide contact details are invited to participate. Once baseline data are collected, GPs are randomly assigned to either a group involving healthy relationship and responding to IPA training plus inviting women for up to 6 sessions of counselling or to a group involving basic education and usual care for women. Outcomes will be evaluated by postal survey at 6 and 12 months following delivery of the intervention. There will be an economic evaluation, and process evaluation involving interviews with women and GPs, to inform understanding about implementation

    2015-10-01

    Carbon fabric/phenolic composites with different weave filaments counts were prepared by dip-coating and hot-press techniques, and then their mechanical and wet tribological properties were investigated based on the analysis of the three-dimensional surface profiles and the pore structures. Results show that the mechanical properties (elastic modulus, flexural modulus, tensile modulus, flexural strength and tensile strength) of the 3K carbon fabric/phenolic composites (Composite A) are better than that of the 12K carbon fabric/phenolic composites (Composite B). Fractured surfaces observation suggests that the dominant tensile failure mechanism is fiber breakage for Composite A and matrix fracture for Composite B. Compared with Composite B, Composite A possesses high friction coefficient in different loads and at different sliding speeds, and the friction coefficient of Composite A is more sensitive to load and sliding speed. The wear rate of Composite B is 39% greater than that of Composite A and the wear features of worn surfaces demonstrate the excellent wear resistance for Composite A. Based on the observation of worn surface, the wear mechanisms are presented.

    This study compared the maximum load, stress, elongation at failure and the mode of failure of three kinds of tendons most frequently used for tendon grafting and tendon transfers, using the Pulvertaft weave suture. Sixty tendons were used from fresh human cadaver upper and lower extremities. The performed repairs included: 9 specimens of flexor digitorum superficialis or profundus tendon with flexor digitorum superficialis or profundus tendon (thick-thick suture), 10 specimens of flexor digitorum superficialis or profundus tendon with palmaris longus tendon (thick-medium thin suture), and 10 specimens of flexor digitorum superficialis or profundus tendon with plantaris tendon (thick-thin suture). Material testing machine was used to test repairs to failure. The mean maximum load at failure increased with the thickness of donor tendon. For the thick-thick specimen, the maximum load at failure was 125 newtons (N), for the thick-medium thin specimen it was 86,8N, and for the thick-thin it was 65,2N. These differences were all statistically significant. The active rehabilitation protocol is possible only with thick-thick connections used, the strength of the thick-medium thin connection is on the border of indications for the active rehabilitation protocol, and the thick-thin connection strength is sufficient only for the passive rehabilitation protocol.

  14. Psychoanalytic case presentations in a weaving thoughts group: on countertransference and group dynamics.

    Salomonsson, Björn

    2012-08-01

    This article summarizes experiences of psychoanalytic case presentations in weaving thoughts (WT) peer groups. The format is presented and illustrated using a session with a group of analysts. In this setting, the frame of the presentation is guaranteed by the moderator. One aim is to create a group setting with many parallels to the analytic situation. A second aim is to discourage members from becoming enmeshed in destructive group functioning, such as internal disputes that may block a deeper understanding of the material. Classical psychoanalysis permits the analyst to reflect behind the patient on the transference-countertransference interplay. However, such reflections may be marred by undetected countertransference problems. Different supervision formats have different ways of helping the analyst with them. The WT format 'copies' the analytic session to the group, hence each member associates to the material in peace. Meanwhile the presenter looks, metaphorically speaking, at the web of their associations at his or her own pace. This may help him or her to confront and reflect on unresolved countertransference issues. This article indicates the method's similarities and differences compared with other formats. Arguments are supported by a child psychotherapy session, but the method is equally suitable for adult case material.

    The need for small-scale product-related biotechnology (BT) is rapidly increasing. An important product among these is high-performance biochips. In these devices, many microchannels are used for separation, filtering and mixing of various materials; therefore, for compactness, these reactions should be carried out in the small space of microfluidic systems. However, there is no turbulence that can induce materials to be mixed or reacted in the microchannel, especially with low Reynolds number laminar flow. Hence, it is difficult to sufficiently mix different materials. To address this problem, we propose the HVW (horizontal and vertical weaving) micromixer having crossed barriers inside of a microchannel, for effective mixing and reacting different materials. From CFD analysis, we have evaluated the mixing mechanism and efficiency of the HVW mixer. In this work, it is shown that the HVW mixer has the maximum mixing efficiency of 89.9% with a short mixing distance of 450 µm at a Reynolds number of 5 with the barrier angle of 30°, when water and water combined with Rhodamine B figment were used as fluids.

    The orb-weaving spider genus Gasteracantha Sundevall, 1833 (Araneidae) is notable for its pronounced sexual size dimorphism. Gasteracantha females are characterized by having a highly sclerotized "spiny" abdomen varying in relative size and number of spines, as well as abdomen dorsally and ventrally provided with varying numbers of sigillae (Cambridge 1879). The genus currently includes 70 described species and 31 subspecies (World Spider Catalog 2014). The Oriental species Gasteracantha geminata (Fabricius, 1798) was originally described from Ramnad (now known as Ramanathapuram) in Tamilnadu State of Southern India based on an unspecified number of female specimen(s). The female of this species has been described and illustrated several times by various authors. Its male is only known from the description of Simon (1895). Simon's original description of the male of G. geminata was supported by two simple but beautiful and informative illustrations: a retrolateral view of the cephalothorax and a dorsal view of the abdomen (Simon 1895, figs. 886, 887). However we lack a clear and detailed description of the male genitalia. The present paper provides detailed redescription of G. geminata and illustrations of the male pedipalp.

    The complete mitochondrial genome of an orb-weaving spider Araneus ventricosus was determined. It is a circular molecule of 14,617 bp in length and contains a standard set of 13 protein-coding genes, 2 ribosomal RNAs, 22 transfer RNAs and a control region. The A + T content of the overall base composition of majority strand (J-strand) is 73.4% (T: 38.5%; C: 10.1%; A: 34.9%; G: 16.5%). Among protein-coding genes, one gene (COI) begins with TTA, two (ATP6 and ND4) start with ATA, three (COII, COIII and ND6) begin with ATT and other seven genes use ATT as initiation codon. COIII and ND3 end with an incomplete stop codon (T), and ND1, ND2 and Cytb are terminated with TAG, while all other genes end with TAA as stop codon. Two regions including tandem repeats were found in the control region (D-loop): a 106 bp sequence tandemly repeated twice and a 195 bp sequence tandemly repeated twice with a partial third (120 bp).

    Orb-weaving spiders produce bioadhesives that are used to capture their prey. In this paper, the physical properties of these adhesives are characterised. The liquid adhesive from Argiope argentata spiders has been studied and the morphological properties of the droplets, including size, shape and volume were determined. An estimation of viscosity and Young's modulus using atomic force microscopy has also been carried out. Morphological characterization confirmed that the liquid adhesive displayed a typical beads-on-a-string (BOAS) morphology on the silk fibres. The experimental data confirmed that the elastic modulus of the liquid adhesive from A. argentata was in the range 20–100 kPa which is in agreement with the Dahlquist criterion for adhesives. - Highlights: • The adhesive of the A. Argentata spiders displayed a beads-on-a-string morphology. • The adhesive drops had an average radius of 6.5 μm. • The adhesive drops had an estimated contact angle of 10°. • The estimated apparent viscosity of the adhesive was in the range 340–680 Pa·s. • AFM indentation measurements provided a Young's modulus value of 70 ± 47 kPa.

    We propose a 'weaving' evolution mechanism, by systematically investigating the products obtained in controlled experiments, to demonstrate the formation of Ni-based 'microflowers' which consists of multiple characteristic dimensions, in which the three dimensional (3D) NiO 'microflower' is constructed by a two-dimensional (2D) nanosheet framework that is derived from weaving one-dimensional (1D) nanowires. We found such unique nanostructures are conducive for the generation of an electrically conductive Ni-network on the nanosheet surface after being exposed to a reducing atmosphere. Our study offers a promising strategy to address the intrinsic issue of poor electrical conductivity for NiO-based materials with significant enhancement of utilization of NiO active materials, leading to a remarkable improvement in the performance of the Ni-NiO microflower based supercapacitor. The optimized Ni-NiO microflower material showed a mass specific capacitance of 1,828 F g(-1), and an energy density of 15.9 Wh kg(-1) at a current density of 0.5 A g(-1). This research not only contributes to understanding the formation mechanism of such 'microflower' structures but also offers a promising route to advance NiO based supercapacitor given their ease of synthesis, low cost, and long-term stability.

Most of the pigments composition in betel-nut root have not been identified, but one of them was condensed tanin. Noni root had pigment composition which consisted of hydrolised tanin, flavonoid and morindon. Pigment composition in turmeric tuber were curcumin, demethoxy curcumin and bis-demethoxy curcumin. Whereas casuarine bark had pigment composition which consisted of delphynidine, cyanydine and phelargonydine. The highest pigment concentration in young leaf teak, betel-nut root, noni root, tumeric tuber and casuarine bark was pheophytine, tanin condensation, morindon, curcumin and cyanidine, respectively.   Keywords: ikat weaving, chlorophyll, carotenoid, anthocyanin

  7. Behavioural analysis of web building anomalies in the orb-weaving spider Zygiella x-notata (Araneae, Araneidae

    Directory of Open Access Journals (Sweden)

    Toscani, Camille

    2012-07-01

    Full Text Available Among animal constructions, spider’s orb webs represent regular geometrical architecture models. Their construction is the result of successive, simple and reproducible behavioural patterns, often considered as stereotyped. It has recently been shown that spider’s building behaviours vary, which can alter web regularity. The final capture spiral results from the laying of successive threads between two radii, here termed ‘spiral units’. We defined a theoretical normal web, as a web in which each turn of the final spiral should be parallel to the preceding one. Weaving of the spiral units sometimes leads to anomalies in the orb web. Anomalies were identified and analysed in the orb-weaving spider Zygiella x-notata (Clerck, 1757. From video recordings of web construction, we noted the displacements of the legs and of the abdomen of the spider. We compared the frequency of displacements, and their duration, between the construction of spiral units that produce a normal turn and ones that produce an anomalous turn. The position of the legs on the web’s threads was also analysed. Results showed that anomalies were not the consequences of a modification in activity but more likely the result of the position on the radii of the fourth leg. These results suggest that spiders use local information to build the final capture spiral.

  8. An investigation to determine the producibility of a 3-D braider and bias direction weaving loom

    1991-01-01

    The development of prototype machines for the production of generalized braid patterns is described. Mechanical operating principles and control strategies are presented for two prototype machines which were fabricated and evaluated. Both machines represent advances over current techniques for forming composite material preforms by enabling near ideal control of fiber orientation. Furthermore, they overcome both the lack of general control of produced fiber architectures and the complexity of other weaving processes that were produced for the same purpose. One prototype, the modified Farley braider, consists of an array of turntables which can be rotated 90 degrees and returned; hence, they can form tracks in the x and y axis. Yarn ends are transported about the surface formed by the turntables using motorized tractors. These tractors are controlled using an optical link with a control circuit and host computer. The tractors are powered through electrical contact with the turntables. The necessary relative motions are produced by a series of linear tractor moves combined with a sequence of turntable rotations. The movement of the tractors about the surface causes the yarns to produce the desired braiding pattern. The second device, the shuttle plate braider, consists of a braiding surface formed by an array of square elements, each separated from its neighbor by a gap. Beneath this surface lies a shuttle plate, which reciprocates first in one axis and then in the other. As this movement takes place, yarn carrying shuttles engage and disengage the plate by means of solenoid activated pins. By selective engagement and disengagement, the shuttles can move the yarn ends in any desired pattern, forming the desired braid. Control power, and control signals, are transmitted from the electronic interface circuit and host computer, via the braiding surface through electrical contact with the shuttles. Motive power is proved to the shuttles by motion of the shuttle plate

And, based on it, the fabric with derivative plain weaves was achieved through trial weaving of the jacquard fabric. Then, through analyzing the pixels' brightness in the fabric, the different fabrics with derivative plain weaves were sorted according to the glossiness with gradual transition effect, which was caused by different degrees of brightness. After that, through choosing the useful plain weaves from the weave model, the corresponding relationship between derivative plain weaves and varying degrees of brightness in art works like paintings was established. Finally, the weaving experiment indicates that the imaging of jacquard silk fabric based on the derivative plain weaves model can produce a special texture effect and bring about a new sense of vision of the jacquard silk fabric.

    Electrode materials are key components for fiber solar cells, and when combined with active layers (for light absorption and charge generation) in appropriate ways, they enable design and fabrication of efficient and innovative device structures. Here, we apply carbon nanotube yarns as counter electrodes in combination with CdSe nanowire-grafted primary electrodes (Ti wire) for making fiber and fabric-shaped photoelectrochemical cells with power conversion efficiencies in the range 1% to 2.9%. The spun-twist long nanotube yarns possess both good electrical conductivity and mechanical flexibility compared to conventional metal wires or carbon fibers, which facilitate fabrication of solar cells with versatile configurations. A unique feature of our process is that instead of making individual fiber cells, we directly weave single or multiple nanotube yarns with primary electrodes into a functional fabric. Our results demonstrate promising applications of semiconducting nanowires and carbon nanotubes in woven photovoltaics.

  1. PDF Weaving - Linking Inventory Data and Monte Carlo Uncertainty Analysis in the Study of how Disturbance Affects Forest Carbon Storage

    Science.gov (United States)

    Healey, S. P.; Patterson, P.; Garrard, C.

    2014-12-01

    Altered disturbance regimes are likely a primary mechanism by which a changing climate will affect storage of carbon in forested ecosystems. Accordingly, the National Forest System (NFS) has been mandated to assess the role of disturbance (harvests, fires, insects, etc.) on carbon storage in each of its planning units. We have developed a process which combines 1990-era maps of forest structure and composition with high-quality maps of subsequent disturbance type and magnitude to track the impact of disturbance on carbon storage. This process, called the Forest Carbon Management Framework (ForCaMF), uses the maps to apply empirically calibrated carbon dynamics built into a widely used management tool, the Forest Vegetation Simulator (FVS). While ForCaMF offers locally specific insights into the effect of historical or hypothetical disturbance trends on carbon storage, its dependence upon the interaction of several maps and a carbon model poses a complex challenge in terms of tracking uncertainty. Monte Carlo analysis is an attractive option for tracking the combined effects of error in several constituent inputs as they impact overall uncertainty. Monte Carlo methods iteratively simulate alternative values for each input and quantify how much outputs vary as a result. Variation of each input is controlled by a Probability Density Function (PDF). We introduce a technique called "PDF Weaving," which constructs PDFs that ensure that simulated uncertainty precisely aligns with uncertainty estimates that can be derived from inventory data. This hard link with inventory data (derived in this case from FIA - the US Forest Service Forest Inventory and Analysis program) both provides empirical calibration and establishes consistency with other types of assessments (e.g., habitat and water) for which NFS depends upon FIA data. Results from the NFS Northern Region will be used to illustrate PDF weaving and insights gained from ForCaMF about the role of disturbance in carbon

  2. Adhesive compatibility of cribellar and viscous prey capture threads and its implication for the evolution of orb-weaving spiders.

    Science.gov (United States)

    Opell, Brent D; Tran, Andrew M; Karinshak, Shannon E

    2011-07-01

    Evolution of orb-weaving spiders that comprise the Orbiculariae clade involved a transition in the composition of prey capture thread that has been challenging to explain. The primitive cribellar threads spun by members of the Deinopoidea subclade resemble the capture threads of their non-orb-web-weaving ancestors and are formed of thousands of fine, dry, protein cribellar fibrils. In contrast, the derived viscous capture threads spun by members of the Araneoidea subclade have regularly spaced, aqueous adhesive droplets. When second instar deinopoid spiderlings emerge from egg sacs they are unable to spin cribellar threads, and, therefore, do not construct orb-webs; whereas second instar araneoids spin capture threads and construct orb-webs. If, as we hypothesize, viscous material evolved to enable second instar spiderlings to construct orb-webs, early araneoids may have spun composite cribellar-viscous capture threads. To examine the functional feasibility of such intermediate capture threads, we compared the adhesion of cribellar threads, viscous threads, and combined cribellar-viscous threads. The stickiness of these combined threads was greater than that of native cribellar or viscous threads alone. The viscous material of Araneus marmoreus threads exhibited a substantial increase in stickiness when combined with cribellar fibrils and that of Argiope aurantia threads a small increase in stickiness when combined with cribellar fibrils. Thus, if early araneoids retained their ability to spin cribellar threads after having evolved glands that produced viscous material, their composite threads could have formed a functional adhesive system that achieved its stickiness at no loss of material economy.

A unique feature of our process is that instead of making individual fiber cells, we directly weave single or multiple nanotube yarns with primary electrodes into a functional fabric. Our results demonstrate promising applications

    Full Text Available Abstract Fethiye, a district of Muğla province, is an important center in which flat weaving activities have been carried out for a long time. Flat weavings have been done for a long time in order to meet weavers’ own needs in the region. Weaving activities in Fethiye include the dye of yarns and the production of flat weavings via a variety of weaving techniques such as kilim, jejim, sili. There is not a professional marketing of flat weavings. However, there are families weaving make to order. Today flat weaving in Fethiye has lost its former importance. However, weaving is still in progress as a handcraft of indigenous. Fethiye flat weavings meet families’ own needs, and sometimes contribute to the home economics by providing them income. In this paper, demographic characteristics of weavers, weaving purposes of weavers, information related weaving preoccupation, yarn, pattern, loom supplies, weaving techniques, the general properties of the woven materials, the current problems and solutions have been analyzed and the current status of flat weaving in the district of Fethiye has been presented.

    In many applications, it is important to understand the individual values of, and relationships between, multiple related scalar variables defined across a common domain. Several approaches have been proposed for representing data in these situations. In this paper we focus on strategies for the visualization of multivariate data that rely on color mixing. In particular, through a series of controlled observer experiments, we seek to establish a fundamental understanding of the information-carrying capacities of two alternative methods for encoding multivariate information using color: color blending and color weaving. We begin with a baseline experiment in which we assess participants' abilities to accurately read numerical data encoded in six different basic color scales defined in the L*a*b* color space. We then assess participants' abilities to read combinations of 2, 3, 4 and 6 different data values represented in a common region of the domain, encoded using either color blending or color weaving. In color blending a single mixed color is formed via linear combination of the individual values in L*a*b* space, and in color weaving the original individual colors are displayed side-by-side in a high frequency texture that fills the region. A third experiment was conducted to clarify some of the trends regarding the color contrast and its effect on the magnitude of the error that was observed in the second experiment. The results indicate that when the component colors are represented side-by-side in a high frequency texture, most participants' abilities to infer the values of individual components are significantly improved, relative to when the colors are blended. Participants' performance was significantly better with color weaving particularly when more than 2 colors were used, and even when the individual colors subtended only 3 minutes of visual angle in the texture. However, the information-carrying capacity of the color weaving approach has its limits. We

    Various applications of multiwalled carbon nanotubes (MWCNT) have been developed. One of these applications is an efficient sheet heating element that is woven from MWCNT-coated yarn. In this research, we assessed the exposure to MWCNT and/or the probability of particle release from broken MWCNT-coated yarn during the weaving process. This was accomplished using particle concentrations, microscopic observation, and carbon analysis. In the weaving process, neither an increase in the number of particles nor a difference in particle-size distribution was observed. In the scanning electron micrographic observation, nanosize MWCNT particles were not detected, but there were micron-size particles containing MWCNT as fragments of the yarn. Carbon analysis showed the concentration of micron-size particles containing MWCNT did not exceed 0.0053 mg-C/m(3) around the loom. This value was much lower than the respirable dust mass concentration. Most of micron-size particles seemed to originate from polyester yarn without MWCNT coating. It is recommended that workers use conventional (even not specialized for nanoparticles) personal protective equipment such as respirators and gloves to prevent exposure to respirable-size MWCNT-containing particles. The probability of MWCNT fall-off from the MWCNT-coated yarn was not detected by transmission electron microscopic observation of MWCNT-coated yarn before or after the weaving process.

    It is well known that the honeybee has good color vision. However, the spectral range in which the bee can see is different from that of the human eye. To study how bees view their world of colors, one has to see through the eyes of the bee, not the eyes of a human. A conventional way to examine the color signals that animals can detect is to measure the surface reflectance spectra and compute the quantum catches of each photoreceptor type based on its known spectral sensitivity. Color signal and color contrast are then determined from the loci of these quantum catches in the color space. While the point-by-point measurements of the reflectance spectra using a standard spectrometer have yielded a significant amount of data for analyzing color signals, the lack of spatial information and low sampling efficiency constrain their applications. Using a special filter coating technique, a set of filters with transmission spectra that were closely matched to the bee's sensitivity spectra of three photoreceptor types (UV, blue, and green) was custom made. By placing these filters in front of a UV/VIS-sensitive CCD camera and acquiring images sequentially, we could collect images of a bee's receptor with only three shots. This allowed a direct visualization of how bees view their world in a pseudo-color RGB display. With this imaging system, spatial and spectral signals of the orb-weaving spider, Nephila pilipes, were recorded, and color contrast images corresponding to the bee's spatial resolution were constructed and analyzed. The result not only confirmed that the color markings of N. pilipes are of high chromatic contrast to the eyes of a bee, but it also indicated that the spatial arrangement of these markings resemble flower patterns which may attract bees to visit them. Thus, it is likely that the orb-weaving spider (N. pilipes) deploys a similar strategy to that of the Australian crab spider (Thomisus spectabilis) to exploit the bee's pre-existing preference for

  18. "The story God is weaving us into": narrativizing grief, faith, and infant loss in US evangelical women's blog communities

    2015-04-01

    This case study explores how US evangelical Christian "mommy blog" communities constitute spaces for the collective memorialization of infant loss. Personal religious blogs feature a rich combination of esthetics, narrative structure, description of religious practices and beliefs, reader interaction, and linked networks. Using a textual approach, I illustrate distinctive features in how pregnancy and infant loss and grief are experienced, shared and memorialized in US women's evangelical blogging communities. I argue that the blog format allows for a (re)narrativization of the devastating experience of infant loss as grieving mothers situate their traumatic personal experiences within the context of an ongoing religious narrative in which blog readers also come to participate. As the blogger tells the story of her own loss to a listening public, it becomes a larger shared story, so that it is not just the child's story but also the author's story, their family's story, and "our story" inclusive of the blog community of readers, "the story God is weaving us into," post by post, day by day. Personal religious blogs and their reading publics, therefore, can provide a medium for the ongoing creation of meaning, faith and community in the context of infant loss.

    The Gz transfer function was described for the orb weaving spider A. sericatus. The functional relationship between the heartrate and the intensity of G is linear in the form of: Y = a Log Gz-1 +k. The heartrate in unrestrained animals was recorded by a laser plethysmograph developed specifically for this purpose. Following a control, sample heartrate were taken postrotation between 1.001 and 1.5 Gz in 6 steps. The underlying distribution of heartrates does not appear significantly different from a Gaussian distribution. A method of varnishing the legs of the spider was developed. This was done in order to compromise the lyriform organs, especially those located on the patellae. The lyriform organ is hypothesized to serve the receptor role in the transduction of gravity related stimuli. In preliminary animals the Gz function, post varnishing of the patellae, appears to be changed in the direction of poorer discrimination. We also observed that the resting heartrate following the varnish procedure is substantially increased.

    We propose a ‘weaving’ evolution mechanism, by systematically investigating the products obtained in controlled experiments, to demonstrate the formation of Ni-based ‘microflowers’ which consists of multiple characteristic dimensions, in which the three dimensional (3D) NiO ‘microflower’ is constructed by a two-dimensional (2D) nanosheet framework that is derived from weaving one-dimensional (1D) nanowires. We found such unique nanostructures are conducive for the generation of an electrically conductive Ni-network on the nanosheet surface after being exposed to a reducing atmosphere. Our study offers a promising strategy to address the intrinsic issue of poor electrical conductivity for NiO-based materials with significant enhancement of utilization of NiO active materials, leading to a remarkable improvement in the performance of the Ni-NiO microflower based supercapacitor. The optimized Ni-NiO microflower material showed a mass specific capacitance of 1,828 F g-1, and an energy density of 15.9 Wh kg-1 at a current density of 0.5 A g-1. This research not only contributes to understanding the formation mechanism of such ‘microflower’ structures but also offers a promising route to advance NiO based supercapacitor given their ease of synthesis, low cost, and long-term stability.

    Urbanisation modifies landscapes at multiple scales, impacting the local climate and changing the extent and quality of natural habitats. These habitat modifications significantly alter species distributions and can result in increased abundance of select species which are able to exploit novel ecosystems. We examined the effect of urbanisation at local and landscape scales on the body size, lipid reserves and ovary weight of Nephila plumipes, an orb weaving spider commonly found in both urban and natural landscapes. Habitat variables at landscape, local and microhabitat scales were integrated to create a series of indexes that quantified the degree of urbanisation at each site. Spider size was negatively associated with vegetation cover at a landscape scale, and positively associated with hard surfaces and anthropogenic disturbance on a local and microhabitat scale. Ovary weight increased in higher socioeconomic areas and was positively associated with hard surfaces and leaf litter at a local scale. The larger size and increased reproductive capacity of N.plumipes in urban areas show that some species benefit from the habitat changes associated with urbanisation. Our results also highlight the importance of incorporating environmental variables from multiple scales when quantifying species responses to landscape modification.

  2. The fatal wound of Hector, according to a drawing by Peter Paul Rubens designed for tapestry weaving.

    2001-02-01

    According to the Iliad(Chapter XXII, Verses 322-329), Hector, while fighting his last duel, was almost entirely protected by bronze armor, with only a small area "where the clavicle marks the boundary between neck and thorax" exposed. It was precisely into this area, "the shorter way to death," that Achilles thrust his lance. This fatal wound, although covering Hector with blood, allowed the victim to pronounce a few words. In designing the Story of Achilles, his fourth and last series of drawings especially designed for tapestry weaving, Rubens depicted Achilles stabbing Hector near the midline of his neck. There is evidence that Rubens was always well acquainted with the literary sources of his pictures. It is also likely that he became familiar with contemporary editions of the Iliad that were enhanced with commentaries. Realizing that the wound depicted in his original drawing should have prevented Hector from speaking, Rubens altered the scene, then showing the lance piercing the cervical vascular bundle. The careful scrutiny for literary accuracy that was typical of Rubens' artistic behavior did not prevent an additional minor imprecision in the final tapestry. Nevertheless, his outstanding expressive power enabled him to give form to a gigantic baroque representation of the death of Hector in masterly fashion.

    In this paper, we detail the manufacturing process for the lenses that will constitute the new two-degree field-of-view Prime Focus Corrector (PFC) for the 4.2m William Herschel Telescope (WHT) optimised for the upcoming WEAVE Multi-Object Spectroscopy (MOS) facility. The corrector, including an Atmospheric Dispersion Corrector (ADC), is made of six large lenses, the largest being 1.1-meter diameter. We describe how the prescriptions of the optical design were translated into manufacturing specifications for the blanks and lenses. We explain how the as-built glass blank parameters were fed back into the optical design and how the specifications for the lenses were subsequently modified. We review the critical issues for the challenging manufacturing process and discuss the trade-offs that were necessary to deliver the lenses while maintaining the optimal optical performance. A short description of the lens optical testing is also presented. Finally, the subsequent manufacturing steps, including assembly, integration, and alignment are outlined.

    Atmospheric deposition is an important source of Hg in remote terrestrial ecosystems of northeastern North America. As high-level invertebrate consumers, orb-weaving spiders (family Araneidae) are excellent subjects for studying the impact of sublethal levels of Hg on forest animals because their webs provide snapshots of behavior and neurological function. Spiders of the diadematus group of the genus Araneus were collected from the Jeffers Brook watershed in the White Mountain National Forest, New Hampshire (USA), and analyzed for Hg content. Webs were photographed and measured to test for correlations between Hg body burden and web structure. Collected spiders contained concentrations of total Hg averaging 44.7 ± 10.0 ng/g Hg (wet mass; mean ± standard deviation), with 37 ± 6% of the total Hg present in the methylmercury form. Mercury loads were likely accumulated through diet (potential prey items contained an average of 43% of the Hg load in collected spiders) and possibly web ingestion. The present study found no direct evidence that the web structure-and thus the prey-capture ability-of spiders in the study area was affected by their Hg body burden. Copyright © 2011 SETAC.

    Porous zinc oxide (ZnO) nanosheet (NS) arrays constructed by connected nanocrystallites were built on weaved metal wire (WMW) via hydrothermal treatment followed by calcination, and used as photoanodes for flexible dye-sensitized solar cells (DSSCs). An overall light-to-electricity conversion efficiency (η) of 2.70% was achieved for the DSSC under 100 mW cm(-2) illumination, and this η was found to be much higher than that of the DSSC with ZnO nanowire (NW) as the photoanode (0.71%). The far superior performance of the DSSC with ZnO-NS is essentially attributed to: (i) the film consisting of nanosheets with interconnected nanocrystallites can allow relatively direct pathways for the transportation of electrons as the nanosheets have a regular structure with the sheets being oriented to the electrode; (ii) the nanocrystallites assembly and porous character of the nanosheets can provide a large surface area for dye adsorption, which is in favor of enhancing the light absorption and the light propagation; (iii) the nanopores embedded in the nanosheet can act as "branch lines" for more efficient electrolyte diffusion into the interstice of the densely packed nanosheets in the array. A further improvement in the efficiency of the DSSC with ZnO-NS was achieved through the atomic layer deposition (ALD) of an ultrathin titanium oxide (TiO2) layer onto the ZnO-NS layer. The larger charge transfer resistance along with the introduction of a TiO2 shell is thought to reduce the surface recombination and thus contribute to the increase in the open circuit voltage (Voc) of the DSCs and higher conversion efficiency (3.09%).

  8. THE END OF COLONIALISM IN ANGOLA AND THE WEAVING OF THE NARRATIVE-NATION, UNDER PEPETELA’S VIEW

    Directory of Open Access Journals (Sweden)

    Full Text Available The novel Yaka, written by the angolan writer Pepetela, is structured in five segments: “The mouth – 1890-/1904”, “The eyes -1917”, “The he­art-1940/1941”, “The sex-1961”, and “The legs-1975”. Each segment corres­ponds to a generation of the Semedo’s family whose journey begins with the banishment of Oscar, Portuguese, and ends with Joel, Oscar’s great-grandchild as a member of the MPLA ranks; this is also related to a certain historical time characterized by the beginning of the military conflicts and the stirring up of the fight between the colonizer and those who were being colonized. Despite being labeled in fiction as a story of a Portuguese family of settlers settled in Angola, the Semedo’s saga reaches during its narrative, a wide meaning due to its intrinsic connection with the wars and with all the problems originated as a result of the colonization. The present work aims to show that all this process of rebuilding the past, through fiction, has to do , among other things, with the transcodification of the historiographic context that- the moment it goes through the fiction writer’s ink or, if we prefer, goes through the literary text screen – it suffers many changes. The narrative events described in the novel are threads in the Angolan history rewoven majestically by Pepetela, who with “skill and talent” reorganizes and, at the same time, weaves his “tale-nation”.

    Orb-web weaving spiders and their relatives use multiple types of task-specific silks. The majority of spider silk studies have focused on the ultra-tough dragline silk synthesized in major ampullate glands, but other silk types have impressive material properties. For instance, minor ampullate silks of orb-web weaving spiders are as tough as draglines, due to their higher extensibility despite lower strength. Differences in material properties between silk types result from differences in their component proteins, particularly members of the spidroin (spider fibroin) gene family. However, the extent to which variation in material properties within a single silk type can be explained by variation in spidroin sequences is unknown. Here, we compare the minor ampullate spidroins (MiSp) of orb-weavers and cobweb weavers. Orb-web weavers use minor ampullate silk to form the auxiliary spiral of the orb-web while cobweb weavers use it to wrap prey, suggesting that selection pressures on minor ampullate spidroins (MiSp) may differ between the two groups. We report complete or nearly complete MiSp sequences from five cobweb weaving spider species and measure material properties of minor ampullate silks in a subset of these species. We also compare MiSp sequences and silk properties of our cobweb weavers to published data for orb-web weavers. We demonstrate that all our cobweb weavers possess multiple MiSp loci and that one locus is more highly expressed in at least two species. We also find that the proportion of β-spiral-forming amino acid motifs in MiSp positively correlates with minor ampullate silk extensibility across orb-web and cobweb weavers. MiSp sequences vary dramatically within and among spider species, and have likely been subject to multiple rounds of gene duplication and concerted evolution, which have contributed to the diverse material properties of minor ampullate silks. Our sequences also provide templates for recombinant silk proteins with tailored

    In order to study the acoustic insulation property of honeycomb weave fabric/PVC composite material, a honeycomb weave fabric with the same surface density but different repetitions of weave was woven on an automatic sample loom using 58.3 tex × 2 cotton yarn as warp and weft. Honeycomb weave fabric/PVC composite material was fabricated using the halloysite nanotubes (HNTs) filled polyvinyl chloride (PVC) as substrate, and then a sandwich structure composite was made with the honeycomb weave fabric/PVC composite as core material. The sound insulation quality of prepared samples was tested by acoustic analyzer of two-channel. The results showed that repetitions of weave have great influence on the sound insulation effect of honeycomb weave fabric. When the repetitions of weave are 6, the composite material displays good sound insulation. In the case of sandwich composite material with the honeycomb weave fabric/PVC composite as core material, it exhibits good sound insulation to low frequency when the repetitions of weave are 6, and its good sound insulation to high frequency is found when the repetitions of weave are 14.%为研究蜂窝织物聚氯乙烯(PVC)复合材料的隔音性能,选用58.3 tex×2的棉纱为经纬纱,在自动织样机上织造面密度基本相同而组织循环数不同的蜂窝织物,以埃洛石纳米管(HNTs)填充的PVC为基体,制备蜂窝织物/PVC复合材料,再以蜂窝织物/PVC复合材料为芯材,制备三明治结构复合材料.采用双声道声学分析仪,对制备样品的隔音性能进行测试和分析.结果表明:不同循环数的蜂窝织物对复合材料的隔音效果有很大影响,当组织循环数为6时,复合材料显示了良好的隔音效果;对于蜂窝织物复合材料作为芯材的三明治结构复合材料而言,组织循环数为6时,对低频具有良好的隔音性能,组织循环数为14时,对高频率具有良好的隔音性能.

    This study investigated the bioaccumulation and effects of mercury (Hg) in funnel-web spiders, Agelena labyrinthica, following exposure to sublethal concentrations of Hg(NO3)2 in their drinking water. The results showed that the Hg content in adult A. labyrinthica increased rapidly with the number of days exposed to the Hg(NO3)2 solution, and the mortality of adult spiders within 30 days increased with increased concentrations of Hg(NO3)2 in the drinking water. The total developmental duration of A. labyrinthica exposed to Hg(NO3)2 was significantly longer than in the control spiders, but there were no significant differences in the total developmental duration of spiders among the three treatment groups (exposed to 10, 20 and 50 mg/L Hg(NO3)2 solution). We also compared the web-weaving of the control and treated spiders, and found no significant differences in shape, structure, color, or size of the webs between the control and treated spiders; however, there was a significant difference in web placement between the treatment and control groups. The spiders in the control group appeared to have an episodic-like memory, choosing to weave their five webs in the same corner in the five time periods allowed.

  17. Structure-activity relationships of pyrrolizidine alkaloids in insect chemical defense against the orb-weaving spider Nephila clavipes.

    Pyrrolizidine alkaloids (PAs) are known to protect Arctiidae moths and Danainae and Ithomiinae butterflies against the orb-weaving spider Nephila clavipes (Araneae, Araneidae, Tetragnathinae), which liberates adults of these insects unharmed from its web. We tested against this spider the role of eight PAs and one derived structure [an 89:11 mixture of the 12-membered macrocyclic diester free base integerrimine and senecionine and the respective N-oxide; two hydrolysis products from this mixture (the necine base retronecine, its respective N-oxide, and a mixture of integerriminic and senecionic necic acids); the 12-membered macrocyclic senkirkine; the 9-O-monoester free base senecioylretronecine and its respective N-oxide; and the 9-O-monoester free base callimorphine (a PA biosynthesized only by insects from retronecine)]. The mixture integerrimine-senecionine N-oxide seems to be more active than the respective free base [LibD50 (liberation dose 50) = 0.042 and 0.153 microg/dry weight of prey, respectively], but the difference in activity between the N-oxide and free base of the 9-O-monoester senecioylretronecine was slight (LibD50 = 0.167 and 0.104, respectively). Senkirkine, an otonecine base PA that does not form N-oxide and is not found in insects, was the less active, showing the highest LibD50 (0.354). The difference in antipredator activity between N-oxides and free bases from macrocyclic diesters and monoesters may be correlated with physicochemical properties of these molecules in interaction with the Nephila receptors. For the active structures, there was a significant correlation between dosage and antipredator activity. Both forms of retronecine and a necic acid mixture were inactive, supporting the hypothesis that PAs biosynthesized by insects from retronecine were originally produced and stored in order to optimize chemical defense. Comparison of dose/activity data with reported amounts of PAs in butterflies suggested that, in general, PA

    As a result of analyzing Tang Dynasty silk samites and restoring the weaving techniques that created them, the opening of Silk Road resulted in the exchange of the commodities, culture and technology between the east and the west that became more and more frequent during the Tang dynasty. The warp -faced compound weave (jin - silk) that was popular from Warring States period to Wei and Jin dynasties was gradually replaced by the weft - faced compound weave ( wei - silk). The motifs of the silk were greatly affected by the Middle and Western Asia. Floral patterns combined with animals suggested a mixture of Chinese and western styles, which was called, historically, " Ling Yang Gong Yang". Weaving technology developed from use of the multi - heddle loom to the drawloom in Tang dynasty. Introduction of the drawloom led to great progress in weaving efficiency and artistic expressiveness in textile motifs.%通过分析唐代宝花狮纹锦各项参数,确定它须由大花偻束综提花机制织,据此复原出这项织造技术.并成功复制出宝花狮纹锦。从而可以推断,随着丝绸之路的畅通,唐代中西方商品、文化、技术交流紧密,大花楼束综提花技术已经开始应用,以此为基础.丝绸品种从以前的经锦过渡剑纬锦,织物图案的艺术表现力得以增强.提花织机的生产效率也得到提高。

  10. Microstructural study of the ablation behaviors of 3D fine weave pierced Carbon/Carbon composites using plasma torch at ultra-high temperature

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    A simple and effective method of testing ablation behaviors of carbon/carbon composites at high temperature was provided, which used plasma torch as the heater. The ablation resistance of 3D fine weave pierced carbon/carbon composites at high temperature was also studied. The results show that temperature of the plasma flame is very high which is much closer to the real work environment of carbon/carbon composites. The factors that affect the ablation characters of carbon/carbon composites depend on both the properties of their components and the environmental conditions in which the material is placed. The ablation behaviors of C/C composites change from the center flame region predominantly influenced by sublimation of graphite to the region close to the outer flame influenced mainly by oxidization of graphite. The sublimation ability of carbon matrix is equal to that of carbon fibers but the oxidization ability of carbon fibers is significantly enhanced compared to that of carbon matrix.

  12. Physical and biological determinants of collective behavioural dynamics in complex systems: pulling chain formation in the nest-weaving ant Oecophylla smaragdina.

    Bochynek, Thomas; Robson, Simon K A

    2014-01-01

    The evolution of nest weaving, the inclusion of larval silk in the nest walls, is considered one of the pinnacles of cooperative behaviour in social insects. Within the four ant genera in which this has evolved, Oecophylla are unique in being the only group that precedes the deposition of larval silk by actively manipulating the leaf substrate to form a nest chamber. Here we provide the first descriptions of the manipulation process within a complex-systems framework. Substrate manipulation involves individual ants selecting, grasping and attempting to pull the edge of the substrate. These individuals are then joined by nest mates at the work site, who either select a site beside the first individual or grasp the body of the first or preceding worker to form a chain of pulling ants that together drag and bend the substrate. Site selection by individual workers is not random when confronted with an artificial leaf, with individuals more likely to grasp a substrate at its tip rather than along a more broad edge. The activity of additional individuals is also not random, with their activity being grouped in both space and time. Additional individuals are more likely to join an existing biting individual or pulling group. The positive feedback associated with the early stages of pulling behaviour appears typical for many of the collective actions observed in social insects.

These individuals are then joined by nest mates at the work site, who either select a site beside the first individual or grasp the body of the first or preceding worker to form a chain of pulling ants that together drag and bend the substrate. Site selection by individual workers is not random when confronted with an artificial leaf, with individuals more likely to grasp a substrate at its tip rather than along a more broad edge. The activity of additional individuals is also not random, with their activity being grouped in both space and time. Additional individuals are more likely to join an existing biting individual or pulling group. The positive feedback associated with the early stages of pulling behaviour appears typical for many of the collective actions observed in social insects.

    Full Text Available ResumenEl propósito de este artículo es describir y analizar los rasgos que propician la creación de una comunidad potencial para el aprendizaje en un contexto no formal; en este caso, el estudio se realiza en un taller de tejido. Participaron aproximadamente 11 mujeres, con edades entre los 25 y los 70 años, quienes asistieron durante el año 2010 a un taller de tejido que se desarrolló en una Asociación Vecinal dependiente de la Municipalidad de la ciudad de Río Cuarto, Argentina. Los datos fueron recabados a través de observaciones de clases, entrevistas a los participantes y a la profesora del curso. Los resultados de la investigación muestran que en este contexto no formal se fomenta el despliegue de algunas dimensiones propias de las comunidades de aprendizaje, como: la retroalimentación, la autonomía, las metas compartidas, la identidad, problemas genuinos y la construcción colaborativa del conocimiento. Los resultados hallados refuerzan las tendencias actuales en el campo de la Psicología Educacional, sobre el valor del contexto de aprendizaje, es decir, en el modo en que las personas crean contextos a través de la relación que se establece entre la persona y los componentes de una actividad.AbstractThe creation of learning communities in non formal context education is an important issue in the current agenda Educational Psychology. Various studies have addressed the learning processes that take place in formal context, but less attention has been paid to the role learning of non-formal context. That is why the purpose of this article is to describe and analyze the features that encourage community building potential for learning in a non-formal context; in this case, the study is carried out especially on a weaving workshop. Study participants were about 11 women between 25 and 70 years old, attended in 2010 a weaving workshop which took place in a dependent neighbourhood association of the Municipality of the city of R

    Huang Daopo was a famous cotton textile expert who made great contribution to the household textile industry in ancient China. She not only disseminated the cotton-textile technology in songjiang district of shanghai, but also invented and iraproved some tools of household textile industry. However, most of the researches on Huang Daopo's techniques of pick-weaving and brocading were not clear enough. Based on analysis and study of the relevant historical materials comibination with the field trips of relevant museum in shanghai, it believed that Huang Daopors cotton textile techniques of pick-weaving and brocading used the technique of Li nationality's pick-weaving to make the "bright and cascading" texture based on textile tools of linen and silk of Han nationality.%黄道婆是中国古代著名的棉纺织专家,她对中国古代家庭棉纺织业的贡献非常大,不仅在上海松江地区传播了棉纺织技术,而且还创造和改进了棉纺织工具。然而,目前对于她的“错纱配色、综线挈花”技术的解释不够清晰。通过对大量与黄道婆相关的史料分析和研究,结合上海地区棉纺织方面博物馆的实物考察,认为黄道婆是在汉族丝、麻织造工具的基础上,运用黎族的挑花技术而创造了松江乌泥泾的“粲然若写”的棉纺织品。

  19. Innovative Structural Materials and Sections with Strain Hardening Cementitious Composites

    Science.gov (United States)

    Dey, Vikram

    The motivation of this work is based on development of new construction products with strain hardening cementitious composites (SHCC) geared towards sustainable residential applications. The proposed research has three main objectives: automation of existing manufacturing systems for SHCC laminates; multi-level characterization of mechanical properties of fiber, matrix, interface and composites phases using servo-hydraulic and digital image correlation techniques. Structural behavior of these systems were predicted using ductility based design procedures using classical laminate theory and structural mechanics. SHCC sections are made up of thin sections of matrix with Portland cement based binder and fine aggregates impregnating continuous one-dimensional fibers in individual or bundle form or two/three dimensional woven, bonded or knitted textiles. Traditional fiber reinforced concrete (FRC) use random dispersed chopped fibers in the matrix at a low volume fractions, typically 1-2% to avoid to avoid fiber agglomeration and balling. In conventional FRC, fracture localization occurs immediately after the first crack, resulting in only minor improvement in toughness and tensile strength. However in SHCC systems, distribution of cracking throughout the specimen is facilitated by the fiber bridging mechanism. Influence of material properties of yarn, composition, geometry and weave patterns of textile in the behavior of laminated SHCC skin composites were investigated. Contribution of the cementitious matrix in the early age and long-term performance of laminated composites was studied with supplementary cementitious materials such as fly ash, silica fume, and wollastonite. A closed form model with classical laminate theory and ply discount method, coupled with a damage evolution model was utilized to simulate the non-linear tensile response of these composite materials. A constitutive material model developed earlier in the group was utilized to characterize and

    Summary Background The number of incoming expectant women who have previously experienced cesarean section has increased. This work sought to find the frequency and connections between vaginal deliveries, cesarean sections, and iterative cesarean sections from 2004 to 2008. Material/Methods In all, 828 women with previous cesarean sections were included. From this group, 8282 vaginal deliveries were performed. During these years, 828 women had a history of the cesarean section; in these women, iterative cesarean sections were indicated. To evaluate knowledge of educational material designed for women being prepared for the iterative delivery, we used information compiled on experience from 2002 to 2003; the same approach was used to evaluate the nursing process on interventions and diagnoses of cesarean sections. Results From 2004 to 2008, 11 279 deliveries were performed in the Perinatological Center in České Budějovice; this was significant (Pcesarean section. The number of iterative cesarean sections in women who had already experienced the cesarean section (828) and delivered by cesarean section again is 620. Other data were not significant. Only 2 to 3 pregnancies next to the first cesarean section were statistically significant in 2004 and 2005. Conclusions If a trial of labor after cesarean does not proceed to vaginal birth, the woman will need support and encouragement to express feelings about another cesarean birth. PMID:21278695

  16. Weaving commutators: beyond Fock space

    CERN Document Server

    Arzano, Michele

    2012-01-01

    The symmetrization postulate and the associated Bose/Fermi (anti)-commutators for field mode operators are among the pillars on which local quantum field theory lays its foundations. They ultimately determine the structure of Fock space and are closely connected with the local properties of the fields and with the action of symmetry generators on observables and states. We here show that the quantum field theory describing relativistic particles coupled to three dimensional Einstein gravity as a topological defect must be constructed using a deformed algebra of creation and annihilation operators. This reflects a non-trivial group manifold structure of the classical momentum space and a modification of the Leibniz rule for the action of symmetry generators governed by Newton's constant. We outline various arguments suggesting that, at least at the qualitative level, these three-dimensional results could also apply to real four-dimensional world thus forcing us to re-think the ordinary multiparticle structure ...

    1967-01-01

    A relatively simple method for obtaining ultrathin, frozen sections for electron microscopy has been developed. Tissues, cultured cells, and bacteria may be employed. They are fixed in 1.25–4% glutaraldehyde for 1–4 hr, are washed overnight in buffer at 3°C, and are embedded in 20% thiolated gelatin or pure gelatin. Before sectioning they are partially dehydrated in 50% glycerol, frozen in liquid nitrogen on a modified tissue holder, and subsequently maintained at -70°C with dry ice. Finally, they are sectioned very rapidly with glass knives on a slightly modified Porter-Blum MT-1 microtome in a commercial deep-freeze maintained at -35°C and are floated in the trough of the knife on a 40% solution of dimethylsulfoxide (DMSO). The sections are picked up in plastic loops and transferred to distilled water at room temperature for thawing and removal of the DMSO, placed on grids coated with Formvar and carbon, air-dried, and stained with phosphotungstic acid, sodium silicotungstate, or a triple stain of osmium tetroxide, uranyl acetate, and lead. Large flat sections are obtained in which ultrastructural preservation is good. They are particularly useful for cytochemical studies. PMID:4167504

    织物宽度方向的经纱张力不匀将会造成织造困难并导致织物质量下降。目前,纱线长度补偿使经纱张力均匀化从技术上讲是不可能实现的。德国亚琛工业大学纺织技术研究所(ITA),正在对一个有望减少经纱张力不匀的方式进行可行性和影响的研究。分段经轴系统可用于提高织物质量和制造过程的稳定性,进而提高织造效率,普通经轴被10个很窄的、分别独立控制的分段织轴所取代。%Inhomogeneous warp tension across the fabric width leads to weaving process difficulties and results in poor fabric quality. At present, yarn length compensation and thereby homogenization of warp tension is techni- cally not possible. At Institut far Textiltechnik der RWTH Aachen University (ITA), Aachen/Germany, the feasibility of a promising attempt to reduce warp tension inhomogenity and its effects is being researched. A system of sectional warp beams has been developed to increase fabric quality, process stability and there- by weaving productivity. The common warp beam is replaced by 10 narrow, individually controlled sectional warp beams.

  17. Sectional dentures revisited.

    2012-04-01

    Sectional dentures are constructed in separate parts which join together intra-orally to create a single prosthesis. They are used to exploit undercuts around teeth, hard and soft tissues which require more than one path of insertion, and are usually of split pin or locking bolts design. By using two case studies, we aim to illustrate the provision of sectional dentures and to which situations their uses are best suited. A 30-year-old male was referred to the Department of Prosthetics at the Birmingham Dental Hospital for a replacement upper partial cobalt chrome denture of a Kennedy Class IV bounded saddle. The patient had a history of failed upper cobalt chrome removable partial dentures owing to loss of retention and poor stability over the previous 12 months. A 40-year-old female patient was referred by her GDP for restoration of a bounded saddle in the lower right quadrant with a history of intolerance to previous dentures. These two cases demonstrate the successful use of sectional dentures in the aesthetic zone. Although more technically demanding, they lie well within the scope of general practice and offer patients alternative solutions from dental implants and bridgework. These cases highlight the importance of the use of alternative prosthetic techniques which can be simple and achievable for all practitioners. Sectional dentures are a treatment modality for the edentulous space where the presence of one or more undercuts prevents restoration by more conventional techniques. This paper highlights some of the situations in which sectional dentures can be employed and emphasizes their use in general practice.

    This is the second edition of the first and foremost book on this subject for self-study, training, and course work. Radar cross section (RCS) is a comparison of two radar signal strengths. One is the strength of the radar beam sweeping over a target, the other is the strength of the reflected echo sensed by the receiver. This book shows how the RCS ?gauge? can be predicted for theoretical objects and how it can be measured for real targets. Predicting RCS is not easy, even for simple objects like spheres or cylinders, but this book explains the two ?exact? forms of theory so well that even a

    The development was made of technology to recover 'waste selvages' generated from the weaving process and recycle them as weaving yarn for bath/toiletry products such as bath mats and toilet mats. The FY 1999 results were summarized. Based on the results of the study made in the previous year, research was conducted using a rapier loom made by Saurer Co. to study the effect of change in selvage fabric on the tangling condition of waste yarn. As a result, it was confirmed that 'waste selvage standard' and 'tangling yarn threading chart' were the most suitable. As to the development of technique for winding 'waste selvages,' safety, operability and efficiency were confirmed of the exclusive winding device which moves associated with the waste selvage roller on the yarn supply side. As to the development of technique for sizing, twisting and heat-processing of 'waste selvages,' favorable results were obtained in the test on the sizing of 'waste selvage' in the dyeing process and the heating processing technique using fused yarn. Good results were also obtained in the test using an exclusive double twister on the twisting condition, strength and uniformity of 'waste selvages.' Also in the development of the winding machine corresponding to coarse yarn and the weaving technique corresponding to coarse yarn, the results obtained were favorable. (NEDO)

    Plants are complex structures, changing their shapes in response to environmental factors such as sunlight, water and neighboring plants. However, some mathematical rules can be found in their growth patterns, one of which is the golden section. The golden section can be observed in branching systems, phyllotaxis, flowers and seeds, and often the spiral arrangement of plant organs. In this study, tree, flower and fruit models have been generated by using the corresponding golden section characteristics, resulting in more natural patterns. Furthermore, the golden section can be found in the bifurcate angles of trees and lobed leaves, extending the golden section theory.

    2001-01-01

    An ideal orthogonal woven preform has superior advantages because of its straight warp and weft structure.However,the produced fabric has an undulating surface and uneven distributed yarns that will deteriorate the mechanical property of the end product.For such kind of preform with binder weft through the fabric thickness,warp tension will cause binder weft crimping and binder tension.The binder tension not only causes binder yars to slip along their axial length,but also makes warp pinching and crimping.Warp tension should be calculated and controlled so as to ensure fully binder slippage in weaving process.%理想的正交组织预形件因具有直的经纬纱结构而存在显著的优越性,但实际生产的预形件有起伏不平的表面和不均匀的纱线排列,这会恶化其复合材料的机械性能.研究采用捆绑纬纱穿过织物厚度的这类预形件认为,经纱张力能同时引起捆绑纬纱的弯曲和张力,捆绑纬纱的张力不仅使其滑移,还使经纱积聚和曲屈.因此,在织造过程中,应通过计算确定经纱张力并进行控制,以确保捆绑纱的充分移动.

    Carbonaceous chondrite meteorites have long posed a challenge for thin section makers. The variability in sample hardness among the different types, and sometimes within individual sections, creates the need for an adaptable approach at each step of the thin section making process. This poster will share some of the procedural adjustments that have proven to be successful at the NASA JSC Meteorite Thin Section Laboratory. These adjustments are modifications of preparation methods that have been in use for decades and therefore do not require investment in new technology or materials.

  10. Artificial skin--culturing of different skin cell lines for generating an artificial skin substitute on cross-weaved spider silk fibres.

    Directory of Open Access Journals (Sweden)

    Hanna Wendt

    Full Text Available BACKGROUND: In the field of Plastic Reconstructive Surgery the development of new innovative matrices for skin repair is in urgent need. The ideal biomaterial should promote attachment, proliferation and growth of cells. Additionally, it should degrade in an appropriate time period without releasing harmful substances, but not exert a pathological immune response. Spider dragline silk from Nephila spp meets these demands to a large extent. METHODOLOGY/PRINCIPAL FINDINGS: Native spider dragline silk, harvested directly out of Nephila spp spiders, was woven on steel frames. Constructs were sterilized and seeded with fibroblasts. After two weeks of cultivating single fibroblasts, keratinocytes were added to generate a bilayered skin model, consisting of dermis and epidermis equivalents. For the next three weeks, constructs in co-culture were lifted on an originally designed setup for air/liquid interface cultivation. After the culturing period, constructs were embedded in paraffin with an especially developed program for spidersilk to avoid supercontraction. Paraffin cross-sections were stained in Haematoxylin & Eosin (H&E for microscopic analyses. CONCLUSION/SIGNIFICANCE: Native spider dragline silk woven on steel frames provides a suitable matrix for 3 dimensional skin cell culturing. Both fibroblasts and keratinocytes cell lines adhere to the spider silk fibres and proliferate. Guided by the spider silk fibres, they sprout into the meshes and reach confluence in at most one week. A well-balanced, bilayered cocultivation in two continuously separated strata can be achieved by serum reduction, changing the medium conditions and the cultivation period at the air/liquid interphase. Therefore spider silk appears to be a promising biomaterial for the enhancement of skin regeneration.

    Majumdar, S K

    2001-01-01

    Etymologically, the word 'Caesar' originates from the Latin word 'Caedaere' meaning - 'to cut'. So cutting remains the core point, but little is known about the real origin of the history of Caesarean Section. There is evidence that, the ancient Hindus excelled in surgery and many operations were performed, including caesarean section. This operation was mentioned several times in the Mishnah of Rabbi Judah, the first large commentary on the Hebrew Bible. There are also several mythological anecdotes in Hindu, Buddhist and Greek mythologies. The myth of caesarean section did not even escape the keen eyes of William Skakespeare. The landmarks, treatises and the advancement in this operative procedure are presented in this article.

    Directory of Open Access Journals (Sweden)

    RAPHAEL CÂMARA

    Full Text Available ABSTRACT Cesarean section by maternal request is the one performed on a pregnant woman without medical indication and without contraindication to vaginal delivery. There is great controversy over requested cesarean section. Potential risks include complications in subsequent pregnancies, such as uterine rupture, placenta previa and accreta. Potential benefits of requested cesareans include a lower risk of postpartum hemorrhage in the first cesarean and fewer surgical complications compared with vaginal delivery. Cesarean section by request should never be performed before 39 weeks.

    老子思想隐含丰富的教育内容。老子教育内容以自然本真为主旨,是人类教育及生命永续的希望。但在民族历史隐性抉择的过程中,有为与贪婪的本性注定人类抛弃老子自然本真教育的选择,构造现实教育的制度化、工具化、奴性化、虚伪化、模拟化及人类中心化等有为教育体系,不断强化人与自然的对抗,并导致人类越来越深刻的灾难。如今,为化解人类现实教育与自然本真教育相对决的不利局面,须有效确立以老子教育思想为指导,把握自然本真的基本方向,构建自然性的教育体系,主要包括自然本真的质性教育、情感教育、精神教育、行为教育、宇宙教育和生态教育等,开启本真教育的时代之门,保障人类与自然相和谐一致及同生共荣的长久目标。%Saussure's structural linguistics triggers a rethinking about the relationship between text and the world. For Derrida, the text is a labyrinth of language game, and there is nothing outside text and all things within text do not need any links or supports from outside world. So we don't want the text to represent the truth of the world any more. What we should do is actively plunging into the sea of signifiers. On the contrary, for Foucault, the text is a web of power--weaved body and it is always from and for some certain groups although it seems to be closed, pure and stable. Any self--evidence and commence sense knowledge or text is with some characteristics of hiding power and these powers are tools to produce domination. The difference between Foueault" and Derrida illustrates two distinctive ways to deal with the relationship between the text and the world in postmodern literature.

    Recently, a growing tendency for cesarean birth has been noted both, in Poland and worldwide. Non-obstetric problems constitute a large part of indications for cesarean section. Many ophthalmologists and obstetricians still believe that high myopia, the presence of peripheral retinal degenerations, history of retinal detachment surgery, diabetic retinopathy, or glaucoma are indications for surgical termination of pregnancy. However, these recommendations are not evidence-based. The literature offers no proof that high myopia and previous retinal surgery increase the risk of retinal detachment during spontaneous vaginal delivery. There is only one indication for cesarean section in myopic patients, i.e. the presence of choroidal neovascularization, which can cause subretinal bleeding with acute visual loss. Prolonged and intensified Valsalva maneuver during labor in patients with an active proliferative diabetic retinopathy may be an indication for an elective cesarean section. Uterine contractions during the second stage of vaginal delivery lead to a marked elevation of intraocular pressure. Intraocular pressure fluctuations during the delivery may damage retinal ganglion cells, resulting in further progression of visual field. Thus, glaucoma associated with advanced visual field changes is the next ophthalmic indication for cesarean section. The report presents the current state of knowledge concerning the effect of pregnancy on pre-existing ocular disorders and the influence of physiological changes on the clinical course of these diseases during the stages of natural delivery. The authors discuss also the ophthalmic indications for cesarean section.

    Conclusions: Complications may occur in women who previously had a normal vaginal delivery requiring interventions in the form of caesarean section and is not uncommon. Though to a small extent, they are contributing to rise is total caesarean section rates seen. There are many cases where a caesarean becomes mandatory for her. The fact that a multipara who has had one or more vaginal deliveries should be regarded as an optimistic historical fact, not as diagnostic-criteria for spontaneous delivery of the pregnancy at hand. A parous woman needs good obstetric care to improve maternal and neonatal outcome and still keeping caesarean section to a lower rate.

    Full Text Available Ross W McQuivey,1 Jon E Block2 1Clinical Innovations, Salt Lake City, UT, 2Independent consultant, San Francisco, CA, USA Abstract: There has been a dramatic rise in the frequency of cesarean sections, surpassing 30% of all deliveries in the US. This upsurge, coupled with a decreasing willingness to allow vaginal birth after cesarean section, has resulted in an expansion of the use of vacuum assistance to safely extract the fetal head. By avoiding the use of a delivering hand or forceps blade, the volume being delivered through the uterine incision can be decreased when the vacuum is used properly. Reducing uterine extensions with their associated complications (eg, excessive blood loss in difficult cases is also a theoretical advantage of vacuum delivery. Maternal discomfort related to excessive fundal pressure may also be lessened. To minimize the risk of neonatal morbidity, proper cup placement over the “flexion point” remains essential to maintain vacuum integrity and reduce the chance of inadvertent detachment and uterine extensions. Based on the published literature and pragmatic clinical experience, utilization of the vacuum device is a safe and effective technique to assist delivery during cesarean section.

    Cross-sectional imaging is so important that, six Nobel Prizes have been awarded to the field of nuclear magnetic resonance alone because it revolutionized clinical diagnosis. The BigBrain project supported by up to 1 billion euro each over a time period of 10 years predicts to "revolutionize our ability to understand internal brain organization" (Evan 2013). If we claim that cross-sectional imaging diagnosis is only semi-quantitative, some may believe because no doctor would ever tell their patient that we can observe the changes of this cross-sectional image next time. If we claim that BigBrain will make no difference in clinical medicine, then few would believe because no doctor would ever tell their patient to scan this part of the image and compare it with that from the BigBrain. If we claim that the BigBrain Project and the Human Brain Project have defects in their key method, one might believe it. But this is true. The key lies in the reconstruction of any cross-sectional image along any axis. Using Ga...

    In an environment where community based organizations are asked to do increasingly more to alleviate the effects of complex social problems, networks and coalitions are becoming the answer for increasing scale, efficiency, coordination, and most importantly, social impact. This paper highlights the formation of a poverty reduction coalition in south Florida. Our case study approach chronicles a developing coalition in Miami-Dade County and the role of one organization acting as lead to the initiative. Drawing on interviews with lead organization staff, participant observation field notes, network mapping and analysis of documents and artifacts from the initiative, we analyze the local organizational context and illuminate important processes associated with supporting a developing coalition. Findings offer a picture of the interorganizational relationships in the community using social network analysis and identify the organizational capacity factors that contribute to and inhibit the formation of a cohesive and effective coalition in this context. This study also highlights the utility of an action research approach to organizational learning about coalition-building in such a way that informs decision making.

    Kedia, Hridesh; Dennis, Mark R; Irvine, William T M

    2016-01-01

    We present a general construction of divergence-free knotted vector fields from complex scalar fields, whose closed field lines encode many kinds of knots and links, including torus knots, their cables, the figure-8 knot and its generalizations. As finite-energy physical fields they represent initial states for fields such as the magnetic field in a plasma, or the vorticity field in a fluid. We give a systematic procedure for calculating the vector potential, starting from complex scalar functions with knotted zero filaments, thus enabling an explicit computation of the helicity of these knotted fields. The construction can be used to generate isolated knotted flux tubes, filled by knots encoded in the lines of the vector field. Lastly we give examples of manifestly knotted vector fields with vanishing helicity. Our results provide building blocks for analytical models and simulations alike.

    In this article, we illustrate the application of a number of theoretical frameworks we have used to guide our work in interprofessional education (IPE) and collaborative interprofessional care (IPC). Although we do not claim to be experts in any one of these theories, each has offered important insights that have broadened our understanding of the complexities of interprofessional learning and practice. We have gained an appreciation for an increasing number of theories relevant to IPE and IPC, and, as a result, we have woven together more key principles from different theories to develop activities for all levels of interprofessional learners and clinicians. We pay particular attention to relational competencies, knotworking/idea dominance, targeted tension and situational awareness. We are now drawing on the arts and humanities and complexity theory to foster relationship-building learning. Evaluation of our endeavors will eventually follow these latter theories for methods that better match the human and social experiences that underpin learning. Our "theoretical toolbox" therefore may be of value to educators who develop and implement creative interprofessional learning activities, as well as clinicians interested in moving toward more effective collaboration.

    An optical configuration for the detection of faults was developed and tested. The optical fourier transformation is the basic working principle of the system. When good fabric passes in front of the optical system the Fourier image, captured by the camera, shows well defined spots corresponding to the spatial frequencies of the tissue. If a defect occurs during production on the loom, the pattern changes significantly and a defect is easily detected in real time. A very simple electronic image processing based on thresholding and binary histograms allows to obtain very encouraging performance for its applicability to the looms. A compact device has been realized and tested in real working conditions on the loom.

  10. X-ray Fluorescence Sectioning

    CERN Document Server

    Cong, Wenxiang

    2012-01-01

    In this paper, we propose an x-ray fluorescence imaging system for elemental analysis. The key idea is what we call "x-ray fluorescence sectioning". Specifically, a slit collimator in front of an x-ray tube is used to shape x-rays into a fan-beam to illuminate a planar section of an object. Then, relevant elements such as gold nanoparticles on the fan-beam plane are excited to generate x-ray fluorescence signals. One or more 2D spectral detectors are placed to face the fan-beam plane and directly measure x-ray fluorescence data. Detector elements are so collimated that each element only sees a unique area element on the fan-beam plane and records the x-ray fluorescence signal accordingly. The measured 2D x-ray fluorescence data can be refined in reference to the attenuation characteristics of the object and the divergence of the beam for accurate elemental mapping. This x-ray fluorescence sectioning system promises fast fluorescence tomographic imaging without a complex inverse procedure. The design can be ad...

    in the vital statistics the cesarean section is a cause that makes reference to births and deaths. to analyze the frequency of the cesarean section, the changes brought about in the rates of maternal, perinatal mortality and of natality, and their relation with reliable contraceptive methods. retrospective study realized with the dices of patients of the Coordination of Reproductive Health of the Mexican Institute of the Social Insurance (IMSS) of the state of Aguascalientes (Mexico). The births were registered majors of 20 weeks of gestation, the maternal and perinatal deaths from 1990 to 2007 in the hospitals of the IMSS in Aguascalientes. The rate of cesarean calculated by means of the registry of the number of the same realized per year and they were divided between the total of vaginal and abdominal births, and the result multiplied percent. 201,563 obstetrical events were registered, of which 145,106 corresponded to vaginal childbirths and 56,457 abdominal ones. With these data a global rate of cesarean section of 28% was obtained, with 201,182 new born alive ones and 2,618 perinatal ones. The acceptance of the tubary bilateral occlusion maintained a constant increase during the period of study, like the intrauterine device. The acceptance from the bilateral occlusion was completely different tubary during the cesarean one, in comparison with the childbirth. the long term results show positive influence in the reduction of the rate of natality.

    Cesarean section by maternal request is the one performed on a pregnant woman without medical indication and without contraindication to vaginal delivery. There is great controversy over requested cesarean section. Potential risks include complications in subsequent pregnancies, such as uterine rupture, placenta previa and accreta. Potential benefits of requested cesareans include a lower risk of postpartum hemorrhage in the first cesarean and fewer surgical complications compared with vaginal delivery. Cesarean section by request should never be performed before 39 weeks. RESUMO A cesariana a pedido materno é aquela realizada em uma gestante sem indicações médicas e sem contraindicação para tentativa do parto vaginal. Existe grande controvérsia sobre a realização da cesariana a pedido. Riscos potenciais da cesariana a pedido incluem complicações em gravidezes subsequentes, tais como: rotura uterina, placenta prévia e acretismo. Potenciais benefícios da cesariana a pedido englobam um menor risco de hemorragia pós-parto na primeira cesariana e menos complicações cirúrgicas quando comparada ao parto vaginal. A cesariana a pedido jamais deve ser realizada antes de 39 semanas.

    The increasing need for cross sections far from the valley of stability poses a challenge for nuclear reaction models. So far, predictions of cross sections have relied on more or less phenomenological approaches, depending on parameters adjusted to available experimental data or deduced from systematical relations. While such predictions are expected to be reliable for nuclei not too far from the experimentally known regions, it is clearly preferable to use more fundamental approaches, based on sound physical bases, when dealing with very exotic nuclei. Thanks to the high computer power available today, all major ingredients required to model a nuclear reaction can now be (and have been) microscopically (or semi-microscopically) determined starting from the information provided by a nucleon-nucleon effective interaction. We have implemented all these microscopic ingredients in the TALYS nuclear reaction code, and we are now almost able to perform fully microscopic cross section calculations. The quality of these ingredients and the impact of using them instead of the usually adopted phenomenological parameters will be discussed. (authors)

    In order to research the fatigue reliability of the vehicle powertrain system, a new load spectrum weave technique correlated customer usage is proposed based on automotive powertrain indoor test. It includes the compressive approach to random load time history based on rain-flow counting method and statistical theory, the speed and gear information corresponding the compression load are also received in the reconstruction spectrum. The traditional relationship between torque level and time is translated into torque level and speed range, meanwhile, the gear position is recorded. The statistical distribution based on different levels of Torque vs speed and vs gear are obtained. Using peak over threshold statistical extreme value theory, a method for extrapolation in the time domain is presented, the extrapolated load spectrum obtained from the extrapolated time signal contains the information about speed and gear. Defining new sampling rate and spline interpolation methods are used to modify the random load spectrum to the test rig properties. The technique can combine the real customer usage data to vehicle powertrain test bench, and avoid the test blindness.

    Full Text Available The papers in this thematic section were originally presented in two venues. Approximately half of the contributions were delivered first in a session at the Annual Meeting of the Central States Anthropological Society in Indianapolis, Indiana in March, 1995. The full complement of presentations took place at the 94th Annual Meeting of the American Anthropological Association in Washington, D.C., in November, 1995. Two participants in the Washington symposium chose not to include their papers in this section. A number of the papers have thus benefitted from several stages of discussion and criticism. While anthropologists (and especially archaeologists dominated both panels, the disciplinary breadth represented by the various members contributed to an invigorating discussion which we now bring to the pages of this journal. In this attempt to reach a broad audience, however, we realize there is the problem of disciplinary specificity, i.e., the particular approaches and data with which scholars deal may not be easily comprehensible to those in other fields. For the current collection, this issue is especially acute for prehistorians, whose focus on the material record and a specialized archaeological terminology may confound some readers. The archaeologists have made efforts to minimize the use of esoteric jargon. In addition, chronological periods are clearly defined in order to fix the temporal setting. While some readers may already be very familiar with the periods in question, we thought it best to err on the side of caution.

    There are eight papers in this section. Some of the fundamentals of atmospheric dispersion of pollutants are examined with theoretical analyses as well as detailed experimental investigations. Emphasis has been placed on analyzing and summarizing previous experimental dispersion data with more realistic and fundamentally sound approaches to plume behavior. The goal is to finalize improved short-range dispersion models from existing data, removing inconsistencies and inadequacies in presently applied assessment models. Dispersion and transport efforts in the future should aim toward evaluating plume behavior on meso and regional scales. The complex features of flow and dispersion through storms, and in the vicinity of significant terrain characteristics influencing local to regional circulations must receive future emphasis. (auth)

Undoubtedly, in order tounderstand the case, it is necessary to discuss the matter in detail.Which factor had what share on the rise in prices?Was the financialinstability as a result of the changes on the value of the kuruş the mosteffective factor on this case?Or did the inflation as a result of selling rawmaterials to foreign merchants cause the dramatic rise in prices?If oneof these aspects or another aspect which isn't mentioned here waseffective,when did the reflections of this case in Ottoman lands becomeapparent?Lots of questions and problems like these have been facingOttoman economic historians. In this research, certain facts taken fromthe court register become meaningful by making simple index. It isknown that in index studies related with prices in Ottoman Empirewhich were conducted in the past, data related with the food sector wasgenerally used.When the fact that both the şer’iyye registers and thedata related with the weaving sector were not used sufficiently in indexstudies is taken into consideration it will be understood that this indexshall include some interesting results.According to the image reflectedfrom index,prices started to increase after 1750s.However,the sharpestincreases were observed after 1840s.Moreover this increase occured atan increasing speed andrate.

    From its inception, the Nuclear Data Project at the University of Michigan has concentrated on two major objectives: (1) to carry out carefully controlled nuclear measurements of the highest possible reliability in support of the national nuclear data program, and (2) to provide an educational opportunity for students with interests in experimental nuclear science. The project has undergone a successful transition from a primary dependence on our photoneutron laboratory to one in which our current research is entirely based on a unique pulsed 14 MeV fast neutron facility. The new experimental facility is unique in its ability to provide nanosecond bursts of 14 MeV neutrons under conditions that are clean'' and as scatter-free as possible, and is the only one of its type currently in operation in the United States. It has been designed and put into operation primarily by graduate students, and has met or exceeded all of its important initial performance goals. We have reached the point of its routine operation, and most of the data are now in hand that will serve as the basis for the first two doctoral dissertations to be written by participating graduate students. Our initial results on double differential neutron cross sections will be presented at the May 1993 Fusion Reactor Technology Workshop. We are pleased to report that, after investing several years in equipment assembly and optimization, the project has now entered its data production'' phase.

    Full Text Available Background: The rate of primary cesarean section (CS is on the rise. More and more women report with a history of a previous CS. A trial of vaginal delivery can save these women from the risk of repeat CS. Aims: The study was conducted to assess the safety and success rate of vaginal birth after CS (VBAC in selected cases of one previous lower segment CS (LSCS. Materials and Methods: The prospective observational study was carried out in a tertiary care teaching hospital over a period of two years. One hundred pregnant women with a history of one previous LSCS were enrolled in the study. Results: In the present study, 85% cases had a successful VBAC and 15% underwent a repeat emergency LSCS for failed trial of vaginal delivery. Cervical dilatation of more than 3 cm at the time of admission was a significant factor in favor of a successful VBAC. Birth weight of more than 3,000 g was associated with a lower success rate of VBAC. The incidence of scar dehiscence was 2% in the present study. There was no maternal or neonatal mortality. Conclusion: Trial of VBAC in selected cases has great importance in the present era of the rising rate of primary CS especially in rural areas.

    Full Text Available Several theories of international migration have emerged to explain and predict the patterns created by the international flows of people. While used as an explanatory tool for other sociological phenomena, world-systems analysis has also emerged as a dominant paradigm through which international migration may be explored. In April 2008 Fairfield University in Fairfield, CT hosted the thirty-second annual conference of the Political Economy of the World-System section of the American Sociological Association. The theme was Flow of People and Money across the World-System: Past, Present and Future. The collection of papers presented at this conference was academically rich and produced a wealth of scholarship, some of which is presented in this issue. Vernengo and Bradbury examine the risks associated with dollarization in Ecuador, arguing that although these risks are minimized by the influx of migrant remittances into the country, the trend remains unstable and unsustainable, as was evident in Argentina. Rocha deconstructs the optimistic visions that present remittances as an opportunity for developing countries, instead arguing that they are part and parcel of a process of economic imperialism. Dick and Jorgenson focus on environmental consequences of foreign investment dependence for less-developed countries and how various types of ecological degradation can contribute to mass migration. Kentor, Sobel and Timberlake discuss the hierarchy of global cities through which so much money flows back and forth, and specifically the spatiality of inter-corporate integration in the global economy such as the spatial distribution of intra-firm corporate headquarter-subsidiary networks operations and centrality in transportation networks. Lastly, Degirmen presents a case study of globalization of capital in Turkey and how interest and exchange rate shocks produced particularly interesting effects on capital and liquidity structures.

This cross section is introduced into the Monte Carlo system AIRES to simulate extended air-showers initiated by cosmic ray photons. The impact of the new photoproduction cross section on common shower observables, especially those related to muon production, is compared with previous results.

The contents of this cross section library are based upon the ENDF/B-VI and IRDF-90 cross section libraries and are recommended as a replacement for the DOSCROS84 multigroup library that is widely used by the dosimetry community. Documentation is provided on the rationale for the choice of the cross sections selected for inclusion in this library and on the uncertainty and variation in cross sections presented by state-of-the-art evaluations.

  19. Downhole tool with replaceable tool sleeve sections

    Energy Technology Data Exchange (ETDEWEB)

    Case, W. A.

    1985-10-29

    A downhole tool for insertion in a drill stem includes elongated cylindrical half sleeve tool sections adapted to be non-rotatably supported on an elongated cylindrical body. The tool sections are mountable on and removable from the body without disconnecting either end of the tool from a drill stem. The half sleeve tool sections are provided with tapered axially extending flanges on their opposite ends which fit in corresponding tapered recesses formed on the tool body and the tool sections are retained on the body by a locknut threadedly engaged with the body and engageable with an axially movable retaining collar. The tool sections may be drivably engaged with axial keys formed on the body or the tool sections may be formed with flat surfaces on the sleeve inner sides cooperable with complementary flat surfaces formed on a reduced diameter portion of the body around which the tool sections are mounted.

  20. Vertically stabilized elongated cross-section tokamak

    Sheffield, George V.

    1977-01-01

    This invention provides a vertically stabilized, non-circular (minor) cross-section, toroidal plasma column characterized by an external separatrix. To this end, a specific poloidal coil means is added outside a toroidal plasma column containing an endless plasma current in a tokamak to produce a rectangular cross-section plasma column along the equilibrium axis of the plasma column. By elongating the spacing between the poloidal coil means the plasma cross-section is vertically elongated, while maintaining vertical stability, efficiently to increase the poloidal flux in linear proportion to the plasma cross-section height to achieve a much greater plasma volume than could be achieved with the heretofore known round cross-section plasma columns. Also, vertical stability is enhanced over an elliptical cross-section plasma column, and poloidal magnetic divertors are achieved.

  1. Frozen section diagnosis in ophthalmic pathology

    1993-01-01

    Full Text Available Frozen section diagnosis is extensively used in various branches of pathology, but its application in ophthalmic pathology was recognised only in the 1970s. We studied 10 sections of ocular and adenexal lesions by frozen section diagnosis, which included orbital lesions (4 cases, lid lesions (3 cases, and intraocular tissue (1 case. The time taken for processing ranged between 10 to 15 minutes. Diagnoses based on frozen section evaluation included lymphoma, mesenchymal chondrosarcoma, solar keratosis, compound naevus, silicone oil globules in cataractous lens, neurofibromatosis, pseudotumour, retinoblastoma, and chronic blepharitis. Although further histopathologic examination correlated well with the frozen section (100% observations, the diagnosis was deferred in the case of naevus and reactive lymphoid hyperplasia. Our study shows that frozen section diagnosis in ophthalmic surgery is quite reliable and is particularly useful in ocular adenexal lesions

  2. Amplitude-Equalized Microwave C-Section

    CERN Document Server

    Gupta, Shulabh

    2016-01-01

    An active microwave C-section is proposed which provides a flat magnitude transmission in a wide frequency band along with a frequency-dependent group delay response considering practical dissipation losses. The key lies in integrating a constant gain amplifier inside a microwave C-section, which perfectly compensates the distributed conductor and dielectric losses of the coupler, while preserving the intrinsic dispersion of the C-section. The operation of the proposed device is confirmed using numerical analysis.

    Proposed continuous-flow-electrophoresis (CFE) chamber of annular cross section offers advantages over conventional CFE chamber, and wedge-cross-section chamber described in "Increasing Sensitivity in Continuous-Flow Electrophoresis" (MFS-26176). In comparison with wedge-shaped chamber, chamber of annular cross section virtually eliminates such wall effects as electro-osmosis and transverse gradients of velocity. Sensitivity enhanced by incorporating gradient maker and radial (collateral) flow.

  5. Improved Empirical Parametrization of Fragmentation Cross Sections

    CERN Document Server

    Sümmerer, Klaus

    2012-01-01

    A new version is proposed for the universal empirical formula, EPAX, which describes fragmentation cross sections in high-energy heavy-ion reactions. The new version, EPAX 3, can be shown to yield cross sections that are in better agreement with experimental data for the most neutron-rich fragments than the previous version. At the same time, the very good agreement of EPAX 2 with data on the neutron-deficient side has been largely maintained. Comparison with measured cross sections show that the bulk of the data is reproduced within a factor of about 2, for cross sections down to the pico-barn range.

  6. The Golden Section as Optical Limitation.

    Directory of Open Access Journals (Sweden)

    Mark A Elliott

    Full Text Available The golden section, ϕ = (1 + √5/2 = 1.618... and its companion ϕ = 1/ϕ = ϕ -1 = 0.618..., are irrational numbers which for centuries were believed to confer aesthetic appeal. In line with the presence of golden sectioning in natural growth patterns, recent EEG recordings show an absence of coherence between brain frequencies related by the golden ratio, suggesting the potential relevance of the golden section to brain dynamics. Using Mondrian-type patterns comprising a number of paired sections in a range of five section-section areal ratios (including golden-sectioned pairs, participants were asked to indicate as rapidly and accurately as possible the polarity (light or dark of the smallest section in the patterns. They were also asked to independently assess the aesthetic appeal of the patterns. No preference was found for golden-sectioned patterns, while reaction times (RTs tended to decrease overall with increasing ratio independently of each pattern's fractal dimensionality. (Fractal dimensionality was unrelated to ratio and measured in terms of the Minkowski-Bouligand box-counting dimension. The ease of detecting the smallest section also decreased with increasing ratio, although RTs were found to be substantially slower for golden-sectioned patterns under 8-paired sectioned conditions. This was confirmed by a significant linear relationship between RT and ratio (p < .001 only when the golden-sectioned RTs were excluded [the relationship was non-significant for the full complement of ratios (p = .217]. Image analysis revealed an absence of spatial frequencies between 4 and 8 cycles-per-degree that was exclusive to the 8-paired (golden-sectioned patterns. The significance of this was demonstrated in a subsequent experiment by addition of uniformly distributed random noise to the patterns. This provided a uniform spatial-frequency profile for all patterns, which did not influence the decrease in RT with increasing ratio but abolished

    2013-01-01

    Cesarean section in buffaloes is an emergency operative procedure being performed prinicipally for uncorrectable uterine torsions and for delivery of fetal monsters. Left paramedian (lateral and parallel to the milk vein) and oblique ventrolateral (above arcus cruralis) are the two common operative sites used for buffalo caesarean section. Although many anesthetic combinations including intravenous and inhalation anesthetic procedures have been experimented in the buffalo species yet most caesarean sections in buffaloes are satisfactorily performed in right lateral recumbency under mild sedation and local infiltration analgesia or paravertebral nerve blocks. The history, indications, anesthesia, operative procedures, post operative complications and future fertility following caesarean section in buffalo are described.

  9. STRESS PROLONGS WOUND HEALING POST CESAREAN SECTION

    Directory of Open Access Journals (Sweden)

    Ah. Yusuf

    2017-07-01

    Full Text Available Introduction: Decision for cesarean section may lead to the stress for women in delivery. Stress response requires longer recovery time in post cesarean section patients. Most of patients who experience stress before and after surgical is associated with wound healing delay. When this condition continues, the wound will have a higher risk of infection. The objective of this study was to analyze correlation between stress and wound healing phase in post cesarean section patients. Method: A cross sectional design was used in this study. The population were women with cesarean section, both elective or emergency, in Delivery Room I RSU Dr. Soetomo Surabaya. Samples were recruited by using purposive sampling, with 28 samples who met to the inclusion criterias. The observed variables were stress and wound healing phase in post cesarean section patient. Stress data were collected by interview and wound healing measurement done by observation on the 3rd day post cesarean section. Result: The result showed that women with stress experience wound healing delay. The characteristic of wound healing delay was prolonged on inflammation phase, nevertheless there was presence of granulation tissue. Spearman’s rho correlation showed that correlation value r=0.675 with p=0.000. Discussion: It can be concluded that there was strong significant correlation between stress and wound healing phase in post cesarean section patients. It is important to give this information to the patients with cesarean section in order to prevent stress and delay in wound healing phase.

    The purpose of this manual is to present a Hazard Breakdown of all jobs normally encountered in the laboratory work of the three sections comprising the Analytic Section, Metallurgy and Control Division of the Technical Department. A Hazard Breakdown is a careful analysis of any job in which the source of possible dangers is clearly indicated for each particular step. The analysis is prepared by individuals who are thoroughly familiar with the specific job or procedure. It is felt that if the hazards herein outlined are recognized by the Laboratory personnel and the suggested safety cautions followed, the chance for injury will be minimized and the worker will become generally more safety conscious. The manual, which is prefaced by the general safety rules applying to all the laboratories, is divided into three main sections, one for each of the three sections into which the Laboratories Division is divided. These sections are as follows: Section 1 -- 200 Area Control; Section 2 -- 100 Area Control; Section 3 -- 300 Area Control, Essential Materials, and Methods Improvement.

    In order to generate photonuclear cross section library for the necessary applications, data evaluation is combined with theoretical evaluation, since photonuclear cross sections measured cannot provide all necessary data. This report recommends a procedure consisting of four steps: (1) analysis of experimental data, (2) data evaluation, (3) theoretical evaluation and, if necessary, (4) modification of results. In the stage of analysis, data obtained by different measurements are reprocessed through the analysis of their discrepancies to a representative data set. In the data evaluation, photonuclear absorption cross sections are evaluated via giant dipole resonance and quasi-deutron mechanism. With photoabsorption cross sections from the data evaluation, theoretical evaluation is applied to determine various decay channel cross sections and emission spectra using equilibrium and preequilibrium mechanism. After this, the calculated results are compared with measured data, and in some cases the results are modified to better describe measurements. (author)

    The article also presents the results of the hydraulic research of the pilot model of the proposed structure. The research has proven that the suppression of any excessive kinetic energy of the discharged water flows falling onto the step-shaped and curving section or the step-shaped section the shape of which is similar to the one made of geosynthetic shells is more efficient that the suppression provided by the smooth section by 50 % to 60 %, and the above suppression is almost equal to the one provided by the well-known step-shaped section. This conclusion can serve as the proof of the high rate of energy suppression demonstrated by the earth-filled dam designed at Samara University of Architecture and Civil Engineering. The dam in question has geosynthetic shells that connect the downstream section to the body of the dam.

    Full Text Available Codonoboea is the largest genus of Gesneriaceae in Peninsular Malaysia with 92 species. Nine sections,   Boeopsis, Codonoboea, Didymanthus, Glossadenia, Heteroboea, Pectinati, Reptantes, Salicini and Venusti, have been erected based on morphological characters, such as habit, leaf arrangement and shape, type of inflorescence, number of flowers, corolla type and nectary type. Recent molecular phylogenetic study using ITS and trnL-F sequences show that only section Heteroboea is monophyletic. While the sections of Codonoboea can no longer be maintained as   formal taxonomic taxa, as informal groupings they are useful in identification and in constructing keys.

    We make a detailed study on the angular differential cross sections of positron–hydrogen collisions by using the momentum-space coupled-channels optical (CCO) method for incident energies below the H ionization threshold. The target continuum and the positronium (Ps) formation channels are included in the coupled-channels calculations via a complex equivalent-local optical potential. The critical points, which show minima in the differential cross sections, as a function of the scattering angle and the incident energy are investigated. The resonances in the angular differential cross sections are reported for the first time in this energy range. The effects of the target continuum and the Ps formation channels on the different cross sections are discussed.

    Frozen section diagnosis provides critical information for immediate surgical management decision making. Over the last several years, there have been some significant advances in treatment of genitourinary cancer, particularly with regard to surgical techniques. These changes in turn impact the type and frequency of intraoperative frozen section requests. In this review, we describe the main indications and diagnostic challenges of frozen section diagnosis during surgeries of each genitourinary organ system including prostate, kidney, bladder, testis, and penis. The pitfalls and approaches to different diagnostic situations are discussed. It is also stressed that pathologists must not only be familiar with the histological diagnosis, but also understand the limitations of frozen section diagnosis and communicate with urologists during the intraoperative treatment decision making process.

    The Lefschetz hyperplane section theorem asserts that a complex affine variety is homotopy equivalent to a space obtained from its generic hyperplane section by attaching some cells. The purpose of this paper is to give an explicit description of attaching maps of these cells for the complement of a complex hyperplane arrangement defined over real numbers. The cells and attaching maps are described in combinatorial terms of chambers. We also discuss the cellular chain complex with coefficient...

    The literature on reconstruction formulas for photoacoustic tomography (PAT) is vast. The various reconstruction formulas differ by used measurement devices and geometry on which the data are sampled. In standard photoacoustic imaging (PAI), the object under investigation is illuminated uniformly. Recently, sectional photoacoustic imaging techniques, using focusing techniques for initializing and measuring the pressure along a plane, appeared in the literature. This paper surveys existing and provides novel exact reconstruction formulas for sectional photoacoustic imaging.

    The PERSUADE project aims at developing poroelastic road surfacing (PERS). A small size field test of PERS was constructed before constructing full scale test sections to gain experience from mixing and laying the PERS material outside the laboratory and to monitor the performance of the pavement over a winter as well as to investigate the performance of the PERS by measuring the characteristics of the surface. The test section was constructed in Denmark on a ramp from a parking area with low...

    Full Text Available The prospects for determining cross sections for compound-nuclear neutron-capture reactions from Surrogate measurements are investigated. Calculations as well as experimental results are presented that test the Weisskopf-Ewing approximation, which is employed in most analyses of Surrogate data. It is concluded that, in general, one has to go beyond this approximation in order to obtain (n,γ cross sections of sufficient accuracy for most astrophysical and nuclear-energy applications.

    New experimental data obtained mainly at the GSI/FRS facility allow to modify the empirical parametrization of fragmentation cross sections, EPAX. It will be shown that minor modifications of the parameters lead to a much better reproduction of measured cross sections. The most significant changes refer to the description of fragmentation yields close to the projectile and of the memory effect of neutron-deficient projectiles.

    In the 1980's the dosimetry community embraced the need for a high fidelity quantification of uncertainty in nuclear data used for dosimetry applications. This led to the adoption of energy-dependent covariance matrices as the accepted manner of quantifying the uncertainty data. The trend for the dosimetry community to require high fidelity treatment of uncertainty estimates has continued to the current time where requirements on nuclear data are codified in standards such as ASTM E 1018. This paper surveys the current state of the dosimetry cross sections and investigates the quality of the current dosimetry cross section evaluations by examining calculated-to-experimental ratios in neutron benchmark fields. In recent years more nuclear-related technical areas are placing an emphasis on uncertainty quantification. With the availability of model-based cross sections and covariance matrices produced by nuclear data codes, some nuclear-related communities are considering the role these covariance matrices should play. While funding within the dosimetry community for cross section evaluations has been very meager, other areas, such as the solar-related astrophysics community and the US Nuclear Criticality Safety Program, have been supporting research in the area of neutron cross sections. The Cross Section Evaluation Working Group (CSEWG) is responsible for the creation and maintenance of the ENDF/B library which has been the mainstay for the reactor dosimetry community. Given the new trends in cross section evaluations, this paper explores the path forward for the US nuclear reactor dosimetry community and its use of the ENDF/B cross-sections. The major concern is maintenance of the sufficiency and accuracy of the uncertainty estimate when used for dosimetry applications. The two major areas of deficiency in the proposed ENDF/B approach are: 1) the use of unrelated covariance matrices in ENDF/B evaluations and 2) the lack of 'due consideration' of

    Full Text Available O objetivo do presente trabalho foi avaliar os efeitos dos parâmetros de tecimento e da velocidade de alimentação sobre a formação da primeira camada de amanteigamento com aço inoxidável austenítico, visando a otimização da operação no sentido de maximizar a relação entre espessura da camada e diluição. Os experimentos foram realizados pelo processo TIG com alimentação de arame, variando-se sistematicamente, e garantindo-se a ortogonalidade do planejamento experimental, a amplitude, o tempo de parada lateral e a velocidade de alimentação, permitindo se encontrar equações estocásticas de predições da geometria resultante do depósito. Através de um programa de otimização, procurou-se os parâmetros de regulagem que levassem a maior relação da área depositada pela área fundida. Escolheu-se como restritor a relação reforço por largura, evitando-se revestimentos com alta convexidade e possibilidade de formação de sobreposição lateral de cordão. Soldagens de validação mostraram a robustez e confirmaram a adequabilidade do método de otimização. Com a metodologia empregada foi possível demonstrar a necessidade, para a otimização do cordão de amanteigamento, de se usar a máxima velocidade de alimentação e o mínimo de tempo na parada lateral. A amplitude ideal é um balanço entre os efeitos sobre a área fundida e convexidade, mostrando uma tendência de adquirir um valor maior do que a faixa central.The objective of the present work was to evaluate the effects of the weaving parameters and of the wire feed speed on the formation of a stainless steel buttering layer, aiming the process optimization by the layer height and dilution maximization.

    The FDA regulates the use of information by biopharmaceutical companies in their promotional activities. Section 114 of the Food and Drug Administration Modernization Act of 1997 (FDAMA) was specifically designed to allow companies to more readily disseminate health care economic information (HCEI) to those who need it for formulary decision making. However, very little HCEI has been distributed promotionally under this provision over the past 17 years. There are recent discussions by stakeholders regarding the need for updates, revisions, or guidance regarding Section 114.In light of recent renewed interest in Section 114 of the FDAMA, the purpose of this commentary is to equip managed care decision makers with the information they need to understand and respond to industry communications that are governed by Section 114. This commentary reviews and synthesizes the regulatory history and language of the statute and changes to the promotion regulation generated by Section 114. It explores the reasons for the section's limited use to date, for recent renewed interest, and why changes by various stakeholders are suggested at this time. Also discussed is what managed care pharmacists need to know about Section 114, and suggestions are included regarding the active role pharmacists can play in this change process. Renewed interest in FDAMA Section 114 appears to stem largely from the increasingly visible and growing interest in comparative effectiveness research, the emergence of "big data," the expanding range of data sources available for deriving HCEI, and recent court decisions that might indicate a change in the regulatory environment. Various stakeholders are proposing recommendations regarding changes to FDAMA Section 114. Managed care pharmacists should be aware that companies are restricted when communicating HCEI promotional messages; this may mean seeing the use of FDAMA Section 114 as the "competent and reliable" effectiveness standard in promotion.

    Frozen section pathology is routinely used for margin assessment of non-melanoma skin cancer (NMSC). Frozen section can also be used for the primary diagnosis of several skin lesions. Limited data exist on the accuracy of frozen section in the diagnosis of NMSC. We performed a retrospective chart review of 300 cases in which frozen section diagnoses were compared with permanent section diagnoses of NMSC. Frozen section and permanent section pathology were concordant 83.3% of the time, with the highest concordance rates noted for basal cell carcinoma (145/153, 95%). Our results show a high level of concordance between frozen section and corresponding permanent section pathology diagnosis for NMSC. The rapidity of frozen section tissue processing and pathology reporting makes this technique useful in dermatologic practice for immediate diagnosis and management of NMSC. Further studies should explore strategies to decrease or eliminate discrepancies between frozen and permanent section diagnosis. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  12. A Technique for Section Thickness Evaluation for Microphotometry and Image Analysis of Sectioned Nuclei

    Directory of Open Access Journals (Sweden)

    R. L. Cabrini

    1998-01-01

    Full Text Available The exact knowledge of the section thickness is a requisite for making the necessary corrections on DNA measurements in tissue sections. Several methods have been proposed to evaluate section thickness, each of them with advantages and disadvantages depending on the type of specimen and equipment available. We herein report another method based on preparation of standard material whose optical density varies as a function of its thickness and is sectioned and measured alongside the tissue specimen. The standards consist of celloidin cylinders stained with the PAS reaction and embedded in paraffin. For prior characterization of the cylinders, sections of different thickness were obtained and mounted. The optical density of each section was measured by direct microphotometry or image analysis. The actual thickness of each section was evaluated following re-embedding of piled groups of sections in a paraffin block and transversal sectioning. The thickness was then measured with a micrometric eye-piece. Optical density and actual thickness of each section were plotted on a normogram curve. Once a given tissue is sectioned alongside with the reference cylinder, the actual thickness is determined by its optical density on the normogram curve.

    Preparation of the temporal bone for light microscopy is an important step in histological studies of the inner ear. Due to the complexity of structures of the inner ear, it is difficult to measure or compare structures of interest without a commonly accepted standardized measure of temporal bone sections. Therefore, standardization of temporal bone sections is very important for histological assessment of sensory hair cells and peripheral ganglion neurons in the cochlear and vestibular systems. The standardized temporal bone sectioning is oriented to a plane parallel to the outer and internal auditory canals. Sections are collected from the epitympanum to the hypotympanum to reveal layers in the order of the crista ampullaris of the superior and lateral semicircular canals, macula utriculi and macula sacculi, superior vestibular ganglion neurons, macula of saccule and inferior vestibular ganglion neurons, cochlear modiolus, endolymphatic duct and endolymphatic sac, and finally the crista ampullaris of the posterior semicircular canal. Moreover, technical details of preparing for temporal bone sectioning including fixation, decalcification, whole temporal bone staining, embedding penetration, and embedding orientation are also discussed.

    1989-08-01

    For the first time, the Illinois State Geological Survey will publish a network of regional cross sections portraying the structural and stratigraphic framework of the entire Illinois basin. The network of 16 structural cross sections radiating outward from the Union Oil 1 Cisne Community well (Sec. 3, T1N, 7E, Wayne County, Illinois) will consist of wireline logs showing formation boundaries and gross lithofacies of the entire stratigraphic column for over 140 wells. Indiana and Kentucky portions of the network will be prepared in conjunction with their respective state geological surveys. Wireline logs are being digitized and stored to allow reproduction of log curves at different scales and in various combinations. Initial cross sections will be published at a vertical scale of 1 in. = 400 ft and a horizontal scale of 1 in. = 8 mi (1:500,000). To assure the most accurate structural and lithologic portrayals possible, numerous wireline logs are being examined in addition to the 140 illustrated on the sections. Available seismic data, sample and core descriptions, and existing structure, isopach, and facies maps are also being used. Text describing the sections will be included on each sheet. Topics will cover a brief history of deposition and structural evolution, distribution of source rocks, reservoir rocks and seals, and significant fields and plays.

    2017-01-01

    Measurements of the inclusive and differential cross-sections for top-quark pair and single top production cross sections in proton-proton collisions with the ATLAS detector at the Large Hadron Collider are presented at center-of-mass energies of 8 TeV and 13 TeV. The inclusive measurements reach high precision and are compared to the best available theoretical calculations. These measurements, including results using boosted tops, probe our understanding of top-pair production in the TeV regime. The results are compared to Monte Carlo generators implementing LO and NLO matrix elements matched with parton showers and NLO QCD calculations. For the t-channel single top measurement, the single top-quark and anti-top-quark total production cross-sections, their ratio, as well as differential cross sections are also presented. A measurement of the production cross-section of a single top quark in association with a W boson, the second largest single-top production mode, is also presented. Finally, measurements of ...

    The most frequently used methods to reduce fusion and total reaction excitation functions were investigated in a very recent paper Canto et al. (Phys Rev C 92:014626, 2015). These methods are widely used to eliminate the influence of masses and charges in comparisons of cross sections for weakly bound and tightly bound systems. This study reached two main conclusions. The first is that the fusion function method is the most successful procedure to reduce fusion cross sections. Applying this method to theoretical cross sections of single channel calculations, one obtains a system independent curve (the fusion function), that can be used as a benchmark to fusion data. The second conclusion was that none of the reduction methods available in the literature is able to provide a universal curve for total reaction cross sections. The reduced single channel cross sections keep a strong dependence of the atomic and mass numbers of the collision partners, except for systems in the same mass range. In the present work we pursue this problem further, applying the reduction methods to systems within a limited mass range. We show that, under these circumstances, the reduction of reaction data may be very useful.

    The Personality Inventory for DSM-5 (PID-5; Krueger et al., 2012) is a dimensional self-report questionnaire designed to measure personality pathology according to the criterion B of the DSM-5 Section III personality model. In the current issue of DSM, this dimensional Section III personality model co-exists with the Section II categorical personality model derived from DSM-IV-TR. Therefore, investigation of the inter-relatedness of both models across populations and languages is warranted. In this study, we first examined the factor structure and reliability of the PID-5 in a Flemish community sample (N=509) by means of exploratory structural equation modeling and alpha coefficients. Next, we investigated the predictive ability of section III personality traits in relation to section II personality disorders through correlations and stepwise regression analyses. Results revealed a five factor solution for the PID-5, with adequate reliability of the facet scales. The variance in Section II personality disorders could be predicted by their theoretically comprising Section III personality traits, but additional Section III personality traits augmented this prediction. Based on current results, we discuss the Section II personality disorder conceptualization and the Section III personality disorder operationalization.

  18. Prospects for Precision Neutrino Cross Section Measurements

    2016-01-28

    The need for precision cross section measurements is more urgent now than ever before, given the central role neutrino oscillation measurements play in the field of particle physics. The definition of precision is something worth considering, however. In order to build the best model for an oscillation experiment, cross section measurements should span a broad range of energies, neutrino interaction channels, and target nuclei. Precision might better be defined not in the final uncertainty associated with any one measurement but rather with the breadth of measurements that are available to constrain models. Current experience shows that models are better constrained by 10 measurements across different processes and energies with 10% uncertainties than by one measurement of one process on one nucleus with a 1% uncertainty. This article describes the current status of and future prospects for the field of precision cross section measurements considering the metric of how many processes, energies, and nuclei have been studied.

    2014-09-01

    Reaction cross section of 22C on a carbon target at an energy of 240 MeV/nucleon have been measured by using the transmission method. The most neutron-rich carbon isotopes 22C is a candidate of a two-neutron halo nucleus. Tanaka et al. [1] measured the reaction cross section of 22C on a hydrogen target at 40 MeV/nucleon. It is showed 22C to have a large matter radius of 5 . 9 +/- 0 . 9 fm, which is much larger than the ones of carbon isotopes with N SAMURAI spectrometer at RIBF. The 22C beam at 240 MeV/nucleon was impinged on a carbon target, and the reaction product was identified by using SAMURAI spectrometer. In the present talk, the extracted reaction cross section and derived matter density distribution of 22C will be presented.

    Full Text Available Youssef’s syndrome is characterized by cyclic hematuria (menouria, absence of vaginal bleeding (amenorrhea, and urinary incontinence due to vesicouterine fistula (VUF, the least common of the urogynecological fistulas. Youssef’s syndrome has a variable clinical presentation. A vesicouterine fistula is an abnormal pathway between the bladder and the uterus. The most common cause is lower segment Cesarean section. Conservative treatment may be appropriate in some cases, but surgery is the definitive treatment. Vesicouterine fistula should be suspected in cases presenting with urinary incontinence even years after Cesarean section. Diagnostic tests as well as necessary appropriate surgery should be performed on cases with suspected vesicouterine fistula. We present a 40-year-old multiparous woman with vesicouterine fistula after primary Cesarean section; she presented with urinary incontinence, hematuria, and amenorrhea 1 year after the birth. Here, we discuss our case with the help of previously published studies found in the literature.
