    Full Text Available We show new applications of the notion of clothed particles in quantum field theory. Its realization by means of the clothing procedure put forward by Greenberg and Schweber allows one to express the total Hamiltonian H and other generators of the Poincaré group for a given system of interacting fields through the creation (annihilation operators for the so-called clothed particles with physical (observed properties. Here such a clothed particle representation is used to calculate the matrix elements (shortly, form factors of the corresponding Nöther current operators sandwiched between the H eigenstates. Our calculations are performed with help of an iterative technique suggested by us earlier when constructing the NN → πNN transition operators. As an illustration, we outline some application of our approach in the spinor quantum electrodynamics.

    A physical-based particle system is employed for cloth modeling supported by two basic algorithms, between which one is the construction of the internal and external forces acting on the particle system in terms of KES-F bending and shearing tests, and the other is the collision algorithm of which the collision detection is carried by means of bi-section of time step and the collision response is handled according to the empirical law for frictionless collision With these algorithms. the geometric state of parcles can be expressed as ordinary differential equationswhich is numerically solved by fourth order Runge- Kutta integration. Different draping figures of cotton fabric and wool fabric prove that such a particle system is suitable for 3D cloth modeling and simulation.

  5. A two-level generative model for cloth representation and shape from shading.

    2007-07-01

    In this paper, we present a two-level generative model for representing the images and surface depth maps of drapery and clothes. The upper level consists of a number of folds which will generate the high contrast (ridge) areas with a dictionary of shading primitives (for 2D images) and fold primitives (for 3D depth maps). These primitives are represented in parametric forms and are learned in a supervised learning phase using 3D surfaces of clothes acquired through photometric stereo. The lower level consists of the remaining flat areas which fill between the folds with a smoothness prior (Markov random field). We show that the classical ill-posed problem-shape from shading (SFS) can be much improved by this two-level model for its reduced dimensionality and incorporation of middle-level visual knowledge, i.e., the dictionary of primitives. Given an input image, we first infer the folds and compute a sketch graph using a sketch pursuit algorithm as in the primal sketch [10], [11]. The 3D folds are estimated by parameter fitting using the fold dictionary and they form the "skeleton" of the drapery/cloth surfaces. Then, the lower level is computed by conventional SFS method using the fold areas as boundary conditions. The two levels interact at the final stage by optimizing a joint Bayesian posterior probability on the depth map. We show a number of experiments which demonstrate more robust results in comparison with state-of-the-art work. In a broader scope, our representation can be viewed as a two-level inhomogeneous MRF model which is applicable to general shape-from-X problems. Our study is an attempt to revisit Marr's idea [23] of computing the 2(1/2)D sketch from primal sketch. In a companion paper [2], we study shape from stereo based on a similar two-level generative sketch representation.

    A study was conducted to experimentally quantify the influence of three variables on the level of resuspension of hazardous aerosol particles from clothing. Variables investigated include physical activity level (two levels, low and high), surface type (four different clothing material types), and time i.e. the rate at which particles resuspend. A mixture of three monodisperse tracer-labelled powders, with median diameters of 3, 5, and 10 microns, was used to "contaminate" the samples, and the resuspended particles were analysed in real-time using an Aerodynamic Particle Sizer (APS), and also by Neutron Activation Analysis (NAA). The overall finding was that physical activity resulted in up to 67% of the contamination deposited on clothing being resuspended back into the air. A detailed examination of the influence of physical activity level on resuspension, from NAA, revealed that the average resuspended fraction (RF) of particles at low physical activity was 28 ± 8%, and at high physical activity was 30 ± 7%, while the APS data revealed a tenfold increase in the cumulative mass of airborne particles during high physical activity in comparison to that during low physical activity. The results also suggest that it is not the contaminated clothing's fibre type which influences particle resuspension, but the material's weave pattern (and hence the material's surface texture). Investigation of the time variation in resuspended particle concentrations indicated that the data were separable into two distinct regimes: the first (occurring within the first 1.5 min) having a high, positive rate of change of airborne particle concentration relative to the second regime. The second regime revealed a slower rate of change of particle concentration and remained relatively unchanged for the remainder of each resuspension event. Copyright © 2013 Elsevier Ltd.

This method could allow for more accurate simulation of particle movement near rigid bodies even with larger SPH particle sizes. If successful, the data-driven model would eliminate the need for a SPH turbulence model and increase the simulation domain size. Continued research beyond the scope of this project will be needed in order to determine the viability of a data-driven model.

    A geometric representation of the (N = 279) masses of quarks, leptons, hadrons and gauge bosons was introduced by employing a Riemann Sphere facilitating the interpretation of the N masses in terms of a single particle, the Masson, which might be in one of the N eigen-states. Geometrically, its mass is the radius of the Riemann Sphere. Dynamically, its derived mass is near the mass of the nucleon regardless of whether it is determined from all N particles of only the hadrons, the mesons or the baryons separately. Ignoring all the other properties of these particles, it is shown that the eigen-values, the polar representation θν of the masses on the Sphere, satisfy the symmetry θν + θN+1-ν = π within less than 1% relative error. In addition, these pair correlations include the pairs θγ + θtop ≃ π and θgluon + θH ≃ π as well as pairing the weak gauge bosons with the three neutrinos.

    efficient. range 1.3 -15x10 sup - sup 3 ms sup - sup 1 were recorded, values which are approximately an order of magnitude higher than the equivalent values onto the floor of the test room. These values suggest that the exposure route of radioactive aerosol particles deposited on the skin may be more significant than hitherto had been assumed. The possible mechanisms leading to this relatively high deposition were investigated experimentally and the results suggested that a combination of factors such as the body's electrostatic field, surface temperature and surface roughness were contributors. A wind tunnel was used to carry out experiments to compare the deposition velocities of a 1.4 mu m mean diameter aerosol onto human body phantoms in a simulated outdoor environment with the values from the test chamber experiments. The measured aerosol deposition velocities were found to vary with wind velocity; values in the range 6.8 - 11x10 sup - sup 3 ms sup - sup 1 were recorded. The clearance of deposited aeroso...

    The loop representation formulation of non-relativistic particles coupled with abelian gauge fields is studied. Both Maxwell and Chern-Simons interactions are separately considered. It is found that the loop-space formulations of these models share significant similarities, although in the Chern-Simons case there exists an unitary transformation that allows to remove the degrees of freedom associated with the paths. As a general result, we find that charge quantization is necessary for the geometric representation to be consistent.

  14. A new representation and probabilistic teleportation of an arbitrary and unknown N-particle state

    2006-01-01

    A new representation of an arbitrary and unknown N-particle state is presented at first. As an application,a scheme for teleporting an arbitrary and unknown N-particle state is proposed when N pairs of two-particle nonmaximally entangled states are utilized as quantum channels. After Alice (sender) makes Bell-state measurement on her particles, Bob (recipient) introduces an auxiliary particle and carries out appropriate unitary transformation on his particle and the auxiliary particle depending on classical information from Alice. Then, yon Neumann measurement that confirms whether the teleportation succeeds or not is performed by Bob on the auxiliary particle. In order to complete the teleportation, another N-1 times operations need to be performed which are similar to the above ones. It can be successfully realized with a certain probability which is determined by the product of the smaller coefficients of non-maximally entangled pairs. All possible unitary transformations are given in detail.

    2001-07-01

    We devised a simple and rapid method for detection of gunshot residue (GSR) particles, using scanning electron microscopy/wavelength dispersive X-ray (SEM/WDX) analysis. Experiments were done on samples containing GSR particles obtained from hands, hair, face, and clothing, using double-sided adhesive coated aluminum stubs (tape-lift method). SEM/WDX analyses for GSR were carried out in three steps: the first step was map analysis for barium (Ba) to search for GSR particles from lead styphnate primed ammunition, or tin (Sn) to search for GSR particles from mercury fulminate primed ammunition. The second step was determination of the location of GSR particles by X-ray imaging of Ba or Sn at a magnification of x 1000-2000 in the SEM, using data of map analysis, and the third step was identification of GSR particles, using WDX spectrometers. Analysis of samples from each primer of a stub took about 3 h. Practical applications were shown for utility of this method.

    A density matrix is usually obtained by solving the Bloch equation, however only a few Hamiltonians' density matrices can be analytically derived. The density matrix for two interacting particles with kinetic coupling is hard to derive by the usual method due to this coupling; this paper solves this problem by using the bipartite entangled state representation.

    2017-01-01

    In the framework of the method of the Faddeev equations in configuration space, the NNK (I = 0) (and KK) kaonic cluster system including two identical particles is considered. We use the formalism of isospin and particle representations to describe the systems. The treatment of I = 1 and I = 0 isospin KN channels is discussed. The presence of the Coulomb force in ppK- channel violates the isospin symmetry of the NNK (I = 0) system. According to the particle representation, NNK is a two-level system of coupled ppK- and ppnl channels with and without the Coulomb energy, respectively. The results of calculations for the bound states with the phenomenological and chiral motivated KN potentials are given for different representations. In particular, new single channel calculations for the ppK- (and K-K- p) cluster are presented. It is shown that the exchange of identical particles plays an important role in the formation of a bound state of the systems. The relation of the exchange and the three-body mass rearrangement effects is discussed. This work is supported by the National Science Foundation grant Supplement to the NSF grant HRD-1345219 and NASA (NNX09AV07A).

  20. Particle number and probability density functional theory and A-representability.

    Science.gov (United States)

    Pan, Xiao-Yin; Sahni, Viraht

    2010-04-28

    In Hohenberg-Kohn density functional theory, the energy E is expressed as a unique functional of the ground state density rho(r): E = E[rho] with the internal energy component F(HK)[rho] being universal. Knowledge of the functional F(HK)[rho] by itself, however, is insufficient to obtain the energy: the particle number N is primary. By emphasizing this primacy, the energy E is written as a nonuniversal functional of N and probability density p(r): E = E[N,p]. The set of functions p(r) satisfies the constraints of normalization to unity and non-negativity, exists for each N; N = 1, ..., infinity, and defines the probability density or p-space. A particle number N and probability density p(r) functional theory is constructed. Two examples for which the exact energy functionals E[N,p] are known are provided. The concept of A-representability is introduced, by which it is meant the set of functions Psi(p) that leads to probability densities p(r) obtained as the quantum-mechanical expectation of the probability density operator, and which satisfies the above constraints. We show that the set of functions p(r) of p-space is equivalent to the A-representable probability density set. We also show via the Harriman and Gilbert constructions that the A-representable and N-representable probability density p(r) sets are equivalent.

  1. Optimized sparse-particle aerosol representations for modeling cloud-aerosol interactions

    Fierce, Laura; McGraw, Robert

    2016-04-01

    Sparse representations of atmospheric aerosols are needed for efficient regional- and global-scale chemical transport models. Here we introduce a new framework for representing aerosol distributions, based on the method of moments. Given a set of moment constraints, we show how linear programming can be used to identify collections of sparse particles that approximately maximize distributional entropy. The collections of sparse particles derived from this approach reproduce CCN activity of the exact model aerosol distributions with high accuracy. Additionally, the linear programming techniques described in this study can be used to bound key aerosol properties, such as the number concentration of CCN. Unlike the commonly used sparse representations, such as modal and sectional schemes, the maximum-entropy moment-based approach is not constrained to pre-determined size bins or assumed distribution shapes. This study is a first step toward a new aerosol simulation scheme that will track multivariate aerosol distributions with sufficient computational efficiency for large-scale simulations.

  2. The method of unitary clothing transformations in the theory of nucleon–nucleon scattering

    2010-04-01

    Full Text Available The clothing procedure, put forward in quantum field theory (QFT by Greenberg and Schweber, is applied for the description of nucleon–nucleon (N –N scattering. We consider pseudoscalar (π and η, vector (ρ and ω and scalar (δ and σ meson fields interacting with 1/2 spin (N and N fermion ones via the Yukawa–type couplings to introduce trial interactions between “bare” particles. The subsequent unitary clothing transformations (UCTs are found to express the total Hamiltonian through new interaction operators that refer to particles with physical (observable properties, the so–called clothed particles. In this work, we are focused upon the Hermitian and energy–independent operators for the clothed nucleons, being built up in the second order in the coupling constants. The corresponding analytic expressions in momentum space are compared with the separate meson contributions to the one–boson–exchange potentials in the meson theory of nuclear forces. In order to evaluate the T matrix of the N–N scattering we have used an equivalence theorem that enables us to operate in the clothed particle representation (CPR instead of the bare particle representation (BPR with its huge amount of virtual processes. We have derived the Lippmann–Schwinger(LS–type equation for the CPR elements of the T–matrix for a given collision energy in the two–nucleon sector of the Hilbert space H of hadronic states and elaborated a code for its numerical solution in momentum space.

  3. Path representation of su(2)_k states I: Operators and particles for k=1,2

    CERN Document Server

    Lamy-Poirier, Joel

    2010-01-01

    This is the first of two articles devoted to the analysis of the path description of the states in integrable modules of su(2)_k. In this first article, the cases k=1,2 are treated in detail, emphasizing a different description in each case (operators vs particles). Our main result for k=1 is a proof of equivalence of two known path representations for the finitized su(2)_1 states, obtained by displaying an explicit bijection. An immediate offshoot is the gain of a new and simple weighting for the (Kyoto) path representation that generalizes to level k. The bijection also suggests two operator constructions for the su(2)_1 paths, a local and a nonlocal one, both interrelated. The nonlocal operator description is the starting point for a direct derivation of the su(2)_1 spinon character. The second part presents an extensive study of the su(2)_2 paths from their particle point of view, where the particles are defined as the path building blocks. The resulting generating functions appear to provide new (at leas...

  4. Representation of Probability Density Functions from Orbit Determination using the Particle Filter

    Science.gov (United States)

    Mashiku, Alinda K.; Garrison, James; Carpenter, J. Russell

    2012-01-01

    Statistical orbit determination enables us to obtain estimates of the state and the statistical information of its region of uncertainty. In order to obtain an accurate representation of the probability density function (PDF) that incorporates higher order statistical information, we propose the use of nonlinear estimation methods such as the Particle Filter. The Particle Filter (PF) is capable of providing a PDF representation of the state estimates whose accuracy is dependent on the number of particles or samples used. For this method to be applicable to real case scenarios, we need a way of accurately representing the PDF in a compressed manner with little information loss. Hence we propose using the Independent Component Analysis (ICA) as a non-Gaussian dimensional reduction method that is capable of maintaining higher order statistical information obtained using the PF. Methods such as the Principal Component Analysis (PCA) are based on utilizing up to second order statistics, hence will not suffice in maintaining maximum information content. Both the PCA and the ICA are applied to two scenarios that involve a highly eccentric orbit with a lower apriori uncertainty covariance and a less eccentric orbit with a higher a priori uncertainty covariance, to illustrate the capability of the ICA in relation to the PCA.

  5. Continuum particle-vibration coupling method in coordinate-space representation for finite nuclei

    CERN Document Server

    Mizuyama, Kazuhito; Vigezzi, Enrico

    2012-01-01

    In this paper we present a new formalism to implement the nuclear particle-vibration coupling (PVC) model. The key issue is the proper treatment of the continuum, that is allowed by the coordinate space representation. Our formalism, based on the use of zero-range interactions like the Skyrme forces, is microscopic and fully self-consistent. We apply it to the case of neutron single-particle states in $^{40}$Ca, $^{208}$Pb and $^{24}$O. The first two cases are meant to illustrate the comparison with the usual (i.e., discrete) PVC model. However, we stress that the present approach allows to calculate properly the effect of PVC on resonant states. We compare our results with those from experiments in which the particle transfer in the continuum region has been attempted. The latter case, namely $^{24}$O, is chosen as an example of a weakly-bound system. Such a nucleus, being double-magic and not displaying collective low-lying vibrational excitations, is characterized by quite pure neutron single-particle stat...

    The wear mechanism of metallic card clothing,used in textile industry, was analyzed. A fast wear test for metallic card clothing racks was developed, which was used as collecting the wear metal particles. The failure type of card clothing was analyzed by the mean of scanning electron microscopy (SEM) and ferro-spectrum technology. The results show that the main wear mechanism of metallic card clothing is low load and high repetition interval fatigue wear caused by friction force between fiber and metal wire teeth.The appropriate quenching microstmcture, which improves the wear resistance of the metallic card clothing rack is also discussed.

  9. Relativistic Dirac Representation of Dynamically-Generated Elementary-Particle Mass

    CERN Document Server

    Chew, Geoffrey F

    2008-01-01

    Special-relativistic dynamically-generated elementary-particle mass is represented by a self-adjoint energy operator acting on a rigged Hilbert space (RHS) of functions over the 6-dimensional Euclidean-group manifold. Even though this operator's eigenvalues correspond to total energy, it is not the generator of infinitesimal wave-function evolution in classical time. Extending formalism which Dirac invented and applied non-relativistically, unitary Poincar\\'e-group representation is provided by the wave functions of a spacelike entity that we call "preon". Six continuous Feynman-path-contacting preon coordinates specify spatial location (3 coordinates), lightlike-velocity-direction (2 coordinates) and transverse polarization (1 coordinate). [Utility of the the term "preon observable" is dubious.] Velocity and spatial location collaborate to define a preon time operator conjugate to the energy operator. In RHS bases alternative to functions over the group manifold, the wave function depends on a preon "velocit...

    2017-06-01

    In the current study, complex-shaped particles are simulated with the Discrete Element Method (DEM) using two different approaches, namely Multi-spheres (MS) and Superquadrics (SQ). Both methods have been used by researchers to represent the shape of real particles. However, despite the growing popularity of utilizing MS and SQ particles in DEM simulations, few insights have been given on the comparison of the macro scale characteristics arising from the two methods. In this respect, initially the characteristics of the two shape representation methods are evaluated in a direct shear test simulation. The results suggest that controlling the sharpness of the edges for SQ particles can lead to a good agreement with the results of MS particles. This way, a set of SQ and MS particles, which are numerically calibrated in the shear tester, are obtained. Furthermore, the macro-scale responses of the numerically calibrated particles are assessed during a slow shearing scenario, which is achieved through simulating quasi-static flow of the particles from a flat-bottom silo. The results for mass discharge, flow profile and wall pressure show a good quantitative agreement. These findings suggest that the numerically calibrated MS and SQ particles in the shear tester can provide similar bulk-scale flow properties. Moreover, the results highlight that surface bumpiness for MS particles and corner sharpness for SQ particles change the characteristics of particles and play a significant role in the shear strength of the material composed of these particles.

    Consider an evolving population, with genealogy given by a Lambda-coalescent that comes down from infinity. We provide rather explicit sampling formulae under this model, for large samples. More precisely, we describe the asymptotic behavior of the site and allele frequency spectrum and the number of segregating sites, as the sample size tends to infinity. A regular variation condition on the driving measure Lambda is assumed for some of the almost sure asymptotic results, but most of out results are valid for a general Lambda-coalescent that comes down from infinity. The proofs rely in part on the recent analysis of the speed of coming down from infinity for Lambda-coalescents, done by the authors in a previous work. state branching processes, and The second goal of this paper is to investigate a remarkable connection between Lambda-coalescents and genealogies of continuous-state branching processes.

    2003-01-01

    Today, clothing and clothing systems for cleanrooms are mainly tested with regard to material properties such as particle generation, particle filtration, and resistance to wear. The dispersal chamber or "body-box" has been used for studying the protective efficacy of clothing systems in use, for example by Hoborn in 1981 (1) and Whyte and Bailey in 1985. A modified dispersal chamber has recently been installed at KTH. Tests and comparative studies have been performed in the dispersal chamber on selected clothing systems. The latest tests have been performed in two parts. In Part 1, each person performed 12 sequences dressed in new, modern cleanroom clothing systems with small variations, such as with and without goggles, different face masks, and different sizes of hoods. In Part 2, each person performed six test sequences with new, modern cleanroom clothing systems with variations in fabrics, and as a comparison, two sequences with pharmaceutical clothing system and surgical clothing system, respectively. The results are given in total number of airborne particles (> or = 0.5 microm per cubic meter) and airborne aerobic CFU per cubic meter. Statistical evaluations of the results have been performed. The source strengths of the contamination source people wearing modern cleanroom clothing systems have been estimated.

  17. Burns and military clothing.

    Burn injury is a ubiquitous threat in the military environment. The risks during combat are well recognised, but the handling of fuel, oil, munitions and other hot or flammable materials during peacetime deployment and training also imposes an inherent risk of accidental burn injury. Over the last hundred years, the burn threat in combat has ranged from nuclear weapons to small shoulder-launched missiles. Materials such as napalm and white phosphorus plainly present a risk of burn, but the threat extends to encompass personnel in vehicles attacked by anti-armour weapons, large missiles, fuel-air explosives and detonations/conflagrations on weapons platforms such as ships. Large numbers of burn casualties were caused at Pearl Harbor, in Hiroshima and Nagasaki, Vietnam, during the Arab/Israeli Wars and in the Falkland Islands conflict. The threat from burns is unlikely to diminish, indeed new developments in weapons seek to exploit the vulnerability of the serviceman and servicewoman to burns. Clothing can be a barrier to some types of burn--both inherently in the properties of the material, but also by trapping air between clothing layers. Conversely, ignition of the clothing may exacerbate a burn. There is hearsay that burnt clothing products within a wound may complicate the clinical management, or that materials that melt (thermoplastic materials) should not be worn if there is a burn threat. This paper explores the incidence of burn injury, the mechanisms of heat transfer to bare skin and skin covered by materials, and the published evidence for the complication of wound management by materials. Even light-weight combat clothing can offer significant protection to skin from short duration flash burns; the most vulnerable areas are the parts of the body not covered--face and hands. Multilayered combat clothing can offer significant protection for short periods from engulfment by flames; lightweight tropical wear with few layers offers little protection. Under

    Full Text Available The functional clothing represents a sustainable development direction of in the field of technical textiles, a bridge between various activity domains, a solution to user’s complex requirements. The research and development potential in the field is supported by the new fibers/ yarns generation, the new technologies and the market niches, as well. Protective clothing is now a major part of textile classified under technical textile. Protective clothing refers to the garment and other fabric related items designed to protect the wearer from harsh environmental effects that results in injuries or death. The innovation, as a result of convergence processing technologies, consumer demands and what is viable on the market, defines the personal protective equipment field. In this article, we present the work of an ESD protective clothing development. Therefore, it has been applied a modern knitting technology, on 7E and 12E STOLL machines, using cotton and wool yarns as base yarn and conductive yarns for plaiting structures. Also, the optimal parameters establishment and the functional requirements are aspects of the research activity performed. The experimental models have been conducted in order to demonstrate the design concept used and choosing the optimal variant. The characterization of the developed experimental variants took into account the evaluation of physico-mechanical and electrical characteristics. From the electrical point of view, the variants have been mainly evaluated through “point to point” method in terms of electrical isolation efficiency dimensional changes analysis.

  7. Massless states and negative mass states of the coupled electron-positron system with completely symmetric representation of the particles

    2016-01-01

    We argue that the free electron and positron can be considered as different, independent particles, each of which is characterized by the complete set of the Dirac plane waves. This completely symmetric representation of the particles makes it necessary to choose another solution of the Dirac equation for the free particle propagator as compared to that currently used in QED. Studying the Bethe-Salpeter equation in the ladder approximation with these free propagators, two new branches of electron-positron bound states which represent the composite bosons, have been found. The first branch corresponds to the negative mass boson whose mass is approximately equal to $-2m$ . These bound states have certain symmetry with respect to the Ps states. For the radiative transition from the Ps states into the negative mass boson states the total energy of the generated gamma quanta should be approximately equal to $4m$. The second branch describes the massless bosons which have been found for the real coupling equal to t...

    2016-01-01

    Resonance plays critical roles in the formation of many physical phenomena, and several methods have been developed for the exploration of resonance. In this work, we propose a new scheme for resonance by solving the Dirac equation in complex momentum representation, in which the resonant states are exposed clearly in complex momentum plane and the resonance parameters can be determined precisely without imposing unphysical parameters. Combining with the relativistic mean-field theory, this method is applied to probe the resonances in $^{120}$Sn with the energies, widths, and wavefunctions being obtained. Comparing with other methods, this method is not only very effective for narrow resonances, but also can be reliably applied to broad resonances.

  9. Spectral representation of the particle production out of equilibrium - Schwinger mechanism in pulsed electric fields

    CERN Document Server

    Fukushima, Kenji

    2014-01-01

    We develop a formalism to describe the particle production out of equilibrium in terms of dynamical spectral functions, i.e. Wigner transformed Pauli-Jordan's and Hadamard's functions. We take an explicit example of a spatially homogeneous scalar theory under pulsed electric fields and investigate the time evolution of the spectral functions. In the out-state we find an oscillatory peak in Hadamard's function as a result of the mixing between positive- and negative-energy waves. The strength of this peak is of the linear order of the Bogoliubov mixing coefficient, whereas the peak corresponding to the Schwinger mechanism is of the quadratic order. Between the in- and the out-states we observe a continuous flow of the spectral peaks together with two transient oscillatory peaks. We also discuss the medium effect at finite temperature and density. We emphasise that the entire structure of the spectral functions conveys rich information on real-time dynamics including the particle production.

  11. A Mathematical Modeling Framework for Analysis of Functional Clothing

    Xiaolin Man

    2007-11-01

    Full Text Available In the analysis and design of functional clothing systems, it is helpful to quantify the effects of a system on a wearer’s physical performance capabilities. Toward this end, a clothing modeling framework for quantifying the mechanical interactions between a given clothing system design and a specific wearer performing defined physical tasks is proposed. The modeling framework consists of three interacting modules: (1 a macroscale fabric mechanics/dynamics model; (2 a collision detection and contact correction module; and (3 a human motion module. In the proposed framework, the macroscopic fabric model is based on a rigorous large deformation continuum-degenerated shell theory representation. Material models that capture the stress-strain behavior of different clothing fabrics are used in the continuum shell framework. The collision and contact module enforces the impenetrability constraint between the fabric and human body and computes the associated contact forces between the two. The human body is represented in the current framework as an assemblage of overlapping ellipsoids that undergo rigid body motions consistent with human motions while performing actions such as walking, running, or jumping. The transient rigid body motions of each ellipsoidal body segment in time are determined using motion capture technology. The integrated modeling framework is then exercised to quantify the resistance that the clothing exerts on the wearer during the specific activities under consideration. Current results from the framework are presented and its intended applications are discussed along with some of the key challenges remaining in clothing system modeling.

    The Carnot cycle and its deduction of maximum conversion efficiency of heat inputted and outputted isothermally at different temperatures necessitated the construction of isothermal and adiabatic pathways within the cycle that were mechanically “reversible”, leading eventually to the Kelvin-Clausius development of the entropy function S with differential dS=dq/T such that ∮CdS=0 where the heat absorption occurs at the isothermal paths of the elementary Carnot cycle. Another required condition is that the heat transfer processes take place infinitely slowly and “reversibly”, implying that rates of transfer are not explicitly featured in the theory. The definition of ‘heat’ as that form of energy that is transferred as a result of a temperature difference suggests that the local mode of transfer of “heat” in the isothermal segments of the pathway implies a Fourier-like heat conduction mechanism which is apparently irreversible, leading to an increase in entropy of the combined reservoirs at either end of the conducting material, and which is deemed reversible mechanically. These paradoxes are circumvented here by first clarifying the terms used before modeling heat transfer as a thermodynamically reversible but mechanically irreversible process and applied to a one dimensional atomic lattice chain of interacting particles subjected to a temperature difference exemplifying Fourier heat conduction. The basis of a “recoverable trajectory” i.e. that which follows a zero entropy trajectory is identified. The Second Law is strictly maintained in this development. A corollary to this zero entropy trajectory is the generalization of the Zeroth law for steady state non-equilibrium systems with varying temperature, and thus to a statement about “equilibrium” in steady state non-thermostatic conditions.

    Inexpensive cloth masks are widely used in developing countries to protect from particulate pollution albeit limited data on their efficacy exists. This study examined the efficiency of four types of masks (three types of cloth masks and one type of surgical mask) commonly worn in the developing world. Five monodispersed aerosol sphere size (30, 100, and 500 nm, and 1 and 2.5 μm) and diluted whole diesel exhaust was used to assess facemask performance. Among the three cloth mask types, a cloth mask with an exhaust valve performed best with filtration efficiency of 80-90% for the measured polystyrene latex (PSL) particle sizes. Two styles of commercially available fabric masks were the least effective with a filtration efficiency of 39-65% for PSL particles, and they performed better as the particle size increased. When the cloth masks were tested against lab-generated whole diesel particles, the filtration efficiency for three particle sizes (30, 100, and 500 nm) ranged from 15% to 57%. Standard N95 mask performance was used as a control to compare the results with cloth masks, and our results suggest that cloth masks are only marginally beneficial in protecting individuals from particles<2.5 μm. Compared with cloth masks, disposable surgical masks are more effective in reducing particulate exposure.Journal of Exposure Science and Environmental Epidemiology advance online publication, 17 August 2016; doi:10.1038/jes.2016.42.

    2014-08-21

    A new approach to density cumulant functional theory is developed that derives density cumulant N-representability conditions from an approximate Fock space unitary transformation. We present explicit equations for the third- and fourth-order two-particle cumulant N-representability, as well as the second-order contributions that depend on the connected three-particle density cumulant. These conditions are used to formulate the ODC-13 method and the non-iterative (λ{sub 3}) correction that employ an incomplete description of the fourth-order two-particle cumulant N-representability and the second-order three-particle correlation effects, respectively. We perform an analysis of the ODC-13 N-representability description for the dissociation of H{sub 2} and apply the ODC-13 method and the (λ{sub 3}) correction to diatomic molecules with multiple bond character and the symmetry-breaking tetraoxygen cation (O{sub 4}{sup +}). For the O{sub 4}{sup +} molecule, the vibrational frequencies of the ODC-13(λ{sub 3}) method do not exhibit spatial symmetry breaking and are in a good agreement with the recent infrared photodissociation experiment. We report the O{sub 4}{sup +} equilibrium structure, harmonic frequencies, and dissociation energy computed using ODC-13(λ{sub 3}) with a diffuse, core-correlated aug-cc-pCVTZ basis set.

  17. A Novel Multi-Sensor Environmental Perception Method Using Low-Rank Representation and a Particle Filter for Vehicle Reversing Safety

    Directory of Open Access Journals (Sweden)

    Zutao Zhang

    2016-06-01

    Full Text Available Environmental perception and information processing are two key steps of active safety for vehicle reversing. Single-sensor environmental perception cannot meet the need for vehicle reversing safety due to its low reliability. In this paper, we present a novel multi-sensor environmental perception method using low-rank representation and a particle filter for vehicle reversing safety. The proposed system consists of four main steps, namely multi-sensor environmental perception, information fusion, target recognition and tracking using low-rank representation and a particle filter, and vehicle reversing speed control modules. First of all, the multi-sensor environmental perception module, based on a binocular-camera system and ultrasonic range finders, obtains the distance data for obstacles behind the vehicle when the vehicle is reversing. Secondly, the information fusion algorithm using an adaptive Kalman filter is used to process the data obtained with the multi-sensor environmental perception module, which greatly improves the robustness of the sensors. Then the framework of a particle filter and low-rank representation is used to track the main obstacles. The low-rank representation is used to optimize an objective particle template that has the smallest L-1 norm. Finally, the electronic throttle opening and automatic braking is under control of the proposed vehicle reversing control strategy prior to any potential collisions, making the reversing control safer and more reliable. The final system simulation and practical testing results demonstrate the validity of the proposed multi-sensor environmental perception method using low-rank representation and a particle filter for vehicle reversing safety.

    All human space missions require significant logistical mass and volume that add an unprecedented burden on longduration missions beyond low-Earth orbit. For these missions with limited cleaning resources, a new wardrobe must be developed to reduce this logistical burden by reducing clothing mass and extending clothing wear. The present studies have been undertaken, for the first time, to measure length of wear and to assess the acceptance of such extended wear. Garments in these studies are commercially available exercise T-shirts and shorts, routine-wear T-shirts, and longsleeved pullover shirts. Fabric composition (cotton, polyester, light-weight, superfine Merino wool, modacrylic, cotton/rayon, polyester/Cocona, modacrylic/Xstatic, modacrylic/rayon, modacrylic/lyocell/aramid), construction (open knit, tight knit, open weave, tight weave), and finishing treatment (none, quaternary ammonium salt) are the independent variables. Eleven studies are reported here: five studies of exercise T-shirts, three of exercise shorts, two of routine wear Tshirts, and one of shirts used as sleep-wear. All studies are conducted in a climate-controlled environment, similar to a space vehicle's. For exercise clothing, study participants wear the garments during aerobic exercise. For routine wear clothing, study participants wear the T-shirts daily in an office or laboratory. Daily questionnaires collected data on ordinal preferences of nine sensory elements and on reason for retiring a used garment. Study 1 compares knitted cotton, polyester, and Merino exercise T-shirts (61 participants), study 2, knitted polyester, modacrylic, and polyester/Cocona exercise T-shirts (40 participants), study 3, cotton and polyester exercise shorts, knitted and woven (70 participants), all three using factorial experimental designs with and without a finishing treatment, conducted at the Johnson Space Center, sharing study participants.

    Occupational exposures to radiation from tritium received at present nuclear facilities and potential exposures at future fusion reactor facilities demonstrate the need for improved protective clothing. Important areas relating to increased protection factors of tritium protective ventilation suits are discussed. These areas include permeation processes of tritium through materials, various tests of film permeability, selection and availability of suit materials, suit designs, and administrative procedures. The phenomenological nature of film permeability calls for more standardized and universal test methods, which would increase the amount of directly useful information on impermeable materials. Improvements in suit designs could be expedited and better communicated to the health physics community by centralizing devlopmental equipment, manpower, and expertise in the field of tritium protection to one or two authoritative institutions.

    Johnson, Glenn; Ganske, Shane

    2013-01-01

    A waterless clothes-cleaning machine has been developed that removes loose particulates and deodorizes dirty laundry with regenerative chemical processes to make the clothes more comfortable to wear and have a fresher smell. This system was initially developed for use in zero-g, but could be altered for 1-g environments where water or other re sources are scarce. Some of these processes include, but are not limited to, airflow, filtration, ozone generation, heat, ultraviolet light, and photocatalytic titanium oxide.

    The Universal Thermal Climate Index (UTCI) was conceived as a thermal index covering the whole climate range from heat to cold. This would be impossible without considering clothing as the interface between the person (here, the physiological model of thermoregulation) and the environment. It was decided to develop a clothing model for this application in which the following three factors were considered: (1) typical dressing behaviour in different temperatures, as observed in the field, resulting in a model of the distribution of clothing over the different body segments in relation to the ambient temperature, (2) the changes in clothing insulation and vapour resistance caused by wind and body movement, and (3) the change in wind speed in relation to the height above ground. The outcome was a clothing model that defines in detail the effective clothing insulation and vapour resistance for each of the thermo-physiological model's body segments over a wide range of climatic conditions. This paper details this model's conception and documents its definitions.

    The image of Indonesian women on international level is partly influenced by the appearance of the First Lady. The role and position of the First Lady is the representation of Indonesian women, because basically the First Lady, as the wife who accompanies the President (head of state), has a strong background of cultural grip, high intellectuality and good personality in her daily lifestyle, including in wearing clothes, and as an ambassador of culture and design. Fashion style of the First Lady always draws praise and criticism from the public. The purpose of this study is to reveal the visualization effects of Indonesian First Ladies’ kebaya clothing style in various state occasions on the image of Indonesian women’s appearances. This study is a qualitative research of visual data that emphasizes the discussion of Kebaya Clothing using semiological study (connotation and denotation meaning) that bring out self-image. The results showed that the style the First Ladies’ Kebaya clothing in every presidency period of their husbands had characteristics both in the style of clothing or hairstyle, indicating self-image. The conclusion of this study reveals that the First Ladies’ Kebaya Clothing (National Clothing) is interpreted as having implied messages because clothing can be observed visually. Implication was done on the construction of learning patterns of clothing, national fashion design and Nusantara ethnic clothing design.

    Based on data gathered through a questionnaire survey with 3,544 respondents in six largest cities in China, the clothing expenditures of Chinese consumers and influential factors are investigated in this paper. It was found that regional differences exist sig nificantly among the cities, possibly due to differences in economy,customs, culture and other factors It was also found that the demographic and soionomic factors including age, gender, marital staus , education level,occupation, and household income have a significant influence on clothing expenditures. Further, the interactive influences of geographic variable with demographic and socioeconomic variables on the clothing expenditures were ex amined. The findings should have useful implications for segmenting Chinese consumers and developing marketing strategies in China.

    The fisherman's work environment consists of many potential risks. A study of occupational accidents in the Norwegian fishing industry in the nine-year period from 1998 to 2006 shows that more than 3/4 of the deaths were caused by loss of fishing vessel or man-overboard accidents. Furthermore, the greatest risk of drowning is found in the smallest fleet. The aim of our project was to develop safer work clothing and through this contribute to a reduction in work accidents and injuries in the fishing fleet. We considered that it is possible to produce protective work clothing that satisfies a specification of requirements covering the fishermen's needs for protection and comfort during work. An end user-centred process including twenty-three personal interviews and a questionnaire was used to clarify the fishermen's needs and wishes before detailed design and product development. We identified an overview of all the fishermen's needs for protection during work, and produced a prioritised list of functional requirements for the clothing. The results show that the clothing previously preferred by fishermen does not satisfy all the users' demands for safety, functionality and comfort. These demands have been taken into consideration when designing improved work clothing for the fishing fleet. A selected number of prototypes were developed on the basis of the established specification of requirements. The prototypes were evaluated according to the users' requirements through tests in SINTEF's Work Physiology Laboratory and on board fishing vessels. The results demonstrate that the new protective clothing satisfies the fishermen's requirements.

  1. Modeling Neanderthal clothing using ethnographic analogues.

    Science.gov (United States)

    Wales, Nathan

    2012-12-01

    Although direct evidence for Neanderthal clothing is essentially nonexistent, information about Paleolithic clothing could provide insights into the biological, technological, and behavioral capabilities of Neanderthals. This paper takes a new approach to understanding Neanderthal clothing through the collection and analysis of clothing data for 245 recent hunter-gatherer groups. These data are tested against environmental factors to infer what clothing humans tend to wear under different conditions. Beta regression is used to predict the proportion of the body covered by clothing according to a location's mean temperature of the coldest month, average wind speed, and annual rainfall. In addition, logistic regression equations predict clothing use on specific parts of the body. Neanderthal clothing patterns are modeled across Europe and over a range of Pleistocene environmental conditions, thereby providing a new appreciation of Paleolithic behavioral variability. After accounting for higher tolerances to cold temperatures, it is predicted that some Neanderthals would have covered up to 80% of their bodies during the winter, probably with non-tailored clothing. It is also likely that some populations covered the hands and feet. In comparison with Neanderthals, Upper Paleolithic modern humans are found to have worn more sophisticated clothing. Importantly, these predictions shed new light on the relationship between Neanderthal extinction and their simple clothing.

    Matching clothes is a challenging task for many blind people. In this paper, we present a proof of concept system to solve this problem. The system consists of 1) a camera connected to a computer to perform pattern and color matching process; 2) speech commands for system control and configuration; and 3) audio feedback to provide matching results for both color and patterns of clothes. This system can handle clothes in deficient color without any pattern, as well as clothing with multiple colors and complex patterns to aid both blind and color deficient people. Furthermore, our method is robust to variations of illumination, clothing rotation and wrinkling. To evaluate the proposed prototype, we collect two challenging databases including clothes without any pattern, or with multiple colors and different patterns under different conditions of lighting and rotation. Results reported here demonstrate the robustness and effectiveness of the proposed clothing matching system.

    A technique for the accurate computation of the electromagnetic fields radiated by a charged particle moving within a parallel-plate waveguide is presented. Based on a transformation of the time-varying current density of the particle into a time-harmonic current density, this technique allows the evaluation of the radiated electromagnetic fields both in the frequency and time domains, as well as in the near- and far-field regions. For this purpose, several accelerated versions of the parallel-plate Green's function in the frequency domain have been considered. The theory has been successfully applied to the multipactor discharge occurring within a two metal-plates region. The proposed formulation has been tested with a particle-in-cell code based on the finite-difference time-domain method, obtaining good agreement.

    Abstract Wave‐particle interactions play a crucial role in energetic particle dynamics in the Earth's radiation belts. However, the relative importance of different wave modes in these dynamics is poorly understood. Typically, this is assessed during geomagnetic storms using statistically averaged empirical wave models as a function of geomagnetic activity in advanced radiation belt simulations. However, statistical averages poorly characterize extreme events such as geomagnetic storms in that storm‐time ultralow frequency wave power is typically larger than that derived over a solar cycle and Kp is a poor proxy for storm‐time wave power.

    2014-10-01

    Volume 2: Improved Sensor and Control Designs Many residential clothes dryers on the market today provide automatic cycles that are intended to stop when the clothes are dry, as determined by the final remaining moisture content (RMC). However, testing of automatic termination cycles has shown that many dryers are susceptible to over-drying of loads, leading to excess energy consumption. In particular, tests performed using the DOE Test Procedure in Appendix D2 of 10 CFR 430 subpart B have shown that as much as 62% of the energy used in a cycle may be from over-drying. Volume 1 of this report shows an average of 20% excess energy from over-drying when running automatic cycles with various load compositions and dryer settings. Consequently, improving automatic termination sensors and algorithms has the potential for substantial energy savings in the U.S.

    Children's clothing is a subject that forms part of the history of pediatrics. Many studies focus on the ideas developed by Locke and Rousseau. Here we choose to focus our study on an author who is rarely quoted: Jacques Ballexserd (1726-1774), "citizen of Geneva," who is little known to historians of pediatrics. However, George Frederic Still (1868-1941) devotes two pages to his views in his Histoire de la Pédiatrie.

    One activity that has been performed by human beings for a long time is washing clothes. Before the invention of the washing machine, clothes were washed by hand and then wrung before drying in the open air. When observed carefully, the wringing of cloth presents some interesting phenomena. However, there are no reports on the physical modelling of this very old activity. This paper reports a simple model to explain the discharge of water from clothes when squeezed. A simple tool was also designed to retrieve data to confirm the theory. We found that the theoretical predictions accurately explained the experimental results. The experiments were conducted on two types of cloth: towels and batik cloth. We also obtained a universal curve to which all the data converged.

    2008-01-01

    Simulating the mechanical behavior of a cloth is a very challenging and important problem in computer animation. The models of bending in most existing cloth simulation approaches are taking the assumption that the cloth is little deformed from a plate shape.Therefore, based on the thin-plate theory, these bending models do not consider the condition that the current shape of the cloth under large deformations cannot be regarded as the approximation to that before deformation, which leads to an unreal static bending. [This paper introduces a dynamic bending model which is appropriate to describe large out-plane deformations such as cloth buckling and bending, and develops a compact implementation of the new model on spring-mass systems. Experimental results show that wrinkles and folds generated using this technique in cloth simulation, can appear and vanish in a more natural way than other approaches.

    2007-01-14

    Molecular ground-state energies and two-electron reduced density matrices (2-RDMs) have recently been computed without the many-electron wave function by constraining the 2-RDM to satisfy a complete set of three-positivity conditions for N representability [D. A. Mazziotti, Phys. Rev. A 74, 032501 (2006)]. Energies at both equilibrium and nonequilibrium geometries are obtained within 0.3% of the correlation energy. In this paper the authors extend this work to examine the accuracy of molecular properties, including multipole moments and components of the ground-state energy, relative to full configuration interaction (FCI). Comparisons are also made with 2-RDM methods with two-positivity conditions and two-positivity plus the generalized T1T2 conditions as well as several approximate wave function methods. Using the 2-RDM method with three-positivity conditions, the authors obtain dipole, quadrupole, and octupole moments for BeH2, BH, H2O, CO, and NH3 at equilibrium geometries that are within 0.04% of their FCI values. In addition, for the potential energy surface of N2, the 2-RDM method with three-positivity yields not only accurate total ground-state energies but also accurate expectation values of the kinetic energy operator, the electron-nuclei potential, and electron-electron repulsion.

    Astronaut clothes for exploration missions beyond low Earth orbit need to satisfy several challenges not met by the currently-used mostly-cotton clothing. A laundering system is not expected to be available, and thus soiled garments must be trashed. Jettisoning waste does not seem feasible at this time. The cabin oxygen concentration is expected to be higher than standard, and thus fabrics must better resist ignition and burning. Fabrics need to be identified that reduce logistical mass, that can be worn longer before disposal, that are at least as comfortable as cotton, and that resist ignition or that char immediately after ignition. Human factors and psychology indicate that crew well-being and morale require a variety of colors and styles to accommodate personal identity and preferences. Over the past four years, the Logistics Reduction Project under NASA's Advanced Exploration Systems Program has sponsored the Advanced Clothing System Task to conduct several ground studies and one ISS study. These studies have evaluated length of wear and personal preferences of commercially-available exercise- and routine-wear garments made from several fabrics (cotton, polyester, Merino wool, and modacrylic), woven and knitted. Note that Merino wool and modacrylic char like cotton in ambient air, while polyester unacceptably melts. This paper focuses on the two components of an International Space Station study, onboard and on the ground, with astronauts and cosmonauts. Fabrics were randomized to participants. Length of wear was assessed by statistical survival analysis, and preference by exact binomial confidence limits. Merino wool and modacrylic t-shirts were worn longer on average than polyester t-shirts. Interestingly, self-assessed preferences were inconsistent with length-of-wear behavior, as polyester was preferred to Merino wool and modacrylic.

    Efforts to decrease the environmental impact of today’s clothing industry across the entire process of production, purchase, maintenance, and disposal can be driven by either suppliers or consumers. Changing the behavior of the latter, however, requires an understanding of current clothing...... consumption patterns—a currently under-researched area. We therefore shed more light on these patterns in the purchase, use and maintenance, and discard phases by analyzing unique data on 4617 adult consumers (aged 18–65) from Germany, Poland, Sweden, and the U.S., who we divide into five segments based...... on clothing consumption behavior. At the low end of the spectrum is a consumer segment that earns the least, consumes mostly budget brand clothing, and is the least open to alternative more environmentally friendly business models such as fashion leasing or clothing libraries.

  1. Unexpected behavioural consequences of preterm newborns' clothing.

    Restrictions of preterm newborns' movements could have consequences ranging from stress enhancement to impairment of their motor development. Therefore, ability to freely express motor activities appears crucial for their behavioural and physiological development. Our aim was to evaluate behavioural issues of two types of clothing used in NICU. We observed 18 healthy 34-37 post-conception week-old preterm newborns, during resting periods, when they were undisturbed by any interventions. Newborns wore either light clothing (bodysuit and a light wrapping) or heavy clothing (pyjamas, cardigan and sleep-sack). The percentages of time each subject spent in different postures were compared between clothing situations. Arm and hand postures differed in relation to clothing: babies bent their arms more and held their hands nearer their heads when in bodysuits than when in sleepwear. Consequently, babies in bodysuits spent more time touching their body or their environment whereas the others generally were touching nothing. Self-touch is an important way to comfort one's self. Heavy clothing may impair self-soothing behaviours of preterm newborn babies that already lack other forms of contact. Results suggest that more attention should be paid to apparently routine and marginal decisions such as choice of clothes.

    Full Text Available System design of cold weather protective clothing is a critical process, as it involvesconsideration of the effects of a number of external and internal parameters like environmental factors and physical, physico-mechanical and psychological parameters. The bulk and weightof the textile materials used in protective clothing should be as low as possible, so thatclothing does not create physical stress and discomfort to the soldier and does not affecthis combat duties adversely. This paper discusses the essential factors involved in thedesigning of cold weather protective clothing and different insulating materials availablein the market for developing better protective clothing. Different stores'developed at theDefence Materials & Stores Research & Development Establishment, Kanpur, the order ofarrangement of various insulating materials in those stores and the protection level achievedare discussed.

    2003-01-01

    This paper advances a new concept of textile-meltglue cloth, and introduces the readers to the basic principle of melt-glue cloth. On the basis of melt spinning, the spinneret can be replaced by a spinning device that consists of an outer spinneret (a loop)and an inner spinneret ( a round plate), and between them there is an interval circle on which the centers of the holes are evenly distributed. When the machine is running, the outer spinneret (or the inner one) is fixed, the inner spinneret (or the outer one)is spinning, and a columnar net will be obtained.Then it will be excided with the help of a cutter in transporting it. Finally the once-forming melt-glue cloth will be produced. Compared with the traditional woven fabric, melt-glue cloth has a lot of special features and a bright future of application.

    2015-03-01

    Manual recovery of spray paints from textiles using a microscope, the routine method in many laboratories, is often laborious. Beating the clothing with a plastic rod, the routine method used for recovery of glass traces within the authors' laboratory, is proposed as an alternative. The efficiency of the method was evaluated by spray tests with fluorescent paint. In these tests, paint particles in the acquired debris samples, as well as those remaining on the textiles, were investigated. The results show that beating is an efficient way to recover and concentrate paint particles. A good efficiency for jeans fabric and rough knitwear is reported. The results appeared to be less satisfactory for smooth woven fabric. Application of the method in casework was effective for graffiti paints as well as for flaked car paint. © 2014 American Academy of Forensic Sciences.

    2009-06-01

    In this study, different conventional personal protection devices (fibrous filters, cartridges for respirators, protective clothing, and gloves) well qualified for micron particles were tested with graphite nanoparticles ranging from 10 to 100 nm (electrical mobility diameter). For this purpose, two specific test benches were designed: one for filter-based devices which are tested under a controlled air flow and other for gloves and protective clothing based on the "through diffusion method." The penetration versus particle size shows for most tested filter media the behavior predicted by the theoretical Brownian capture: penetration decreases when particle diameter decreases. No thermal rebound was detected until 10 nm for graphite nanoparticles. Protective clothes were tested by two methods and same trends were obtained. Nonwoven fabrics (air-tight materials) are much more efficient against nanoparticles than cotton and paper. Gloves tested by "through diffusion technique," in static condition seem to efficiently protect against graphite nanoparticles in spite of their important porosity.

  12. Radioactive contamination incidents involving protective clothing

    1996-10-01

    The study focuses on incidents at Department of Energy (DOE) facilities involving the migration of radioactive contaminants through protective clothing. The authors analyzed 68 occurrence reports for the following factors: (1) type of work; (2) working conditions; (3) type of anti-contamination (anti-C) material; (4) area of body or clothing contaminated; and (5) nature of spread of contamination. A majority of reports identified strenuous work activities such as maintenance, construction, or decontamination and decommissioning (D&D) projects. The reports also indicated adverse working conditions that included hot and humid or cramped work environments. The type of anti-C clothing most often identified was cotton or water-resistant, disposable clothing. Most of the reports also indicated contaminants migrating through perspiration-soaked areas, typically in the knees and forearms. On the basis of their survey, the authors recommend the use of improved engineering controls and resilient, breathable, waterproof protective clothing for work in hot, humid, or damp areas where the possibility of prolonged contact with contamination cannot be easily avoided or controlled.

    Spacetime is modelled by binary relations - by the classes of the automorphisms $\\GL(\\C^2)$ of a complex 2-dimensional vector space with respect to the definite unitary subgroup $\\U(2)$. In extension of Feynman propagators for particle quantum fields representing only the tangent spacetime structure, global spacetime representations are given, formulated as residues using energy-momentum distributions with the invariants as singularities. The associatated quantum fields are characterized by two invariant masses - for time and position - supplementing the one mass for the definite unitary particle sector with another mass for the indefinite unitary interaction sector without asymptotic particle interpretation.

    Full Text Available Fashion marketing explores connection between fashion design and marketing including development, promotion, sales and price aspects of fashion industry. Successful fashion marketing managers are aware that the most important fashion marketing elements are customer trend identification, building strong brands and creating positive image of the producers. This paper presents the findings of a research conducted for the purpose of identifying trends in marketing sector in textile and clothing industry in Croatia. The research was conducted through personal interviews with marketing and company managers in Croatia. The research identified that marketing is insufficiently implemented in Croatian textile and clothing industry, despite growing brand management importance. However, because of lack in marketing knowledge and bad brand management, development of fashion brand is the most critical factor in successful business activity in textile and clothing industry.

  15. Anisotropic Cloth Modeling for Material Fabric

    Zhang, Mingmin; Pan, Zhigengx; Mi, Qingfeng

    Physically based cloth simulation has been challenging the graphics community for more than three decades. With the developing of virtual reality and clothing CAD, it has become the key technique of virtual garment and try-on system. Although it has received considerable attention in computer graphics, due to its flexible property and realistic feeling that the textile engineers pay much attention to, there is not a successful methodology to simulate cloth both in visual realism and physical accuracy. We present a new anisotropic textile modeling method based on physical mass-spring system, which models the warps and wefts separately according to the different material fabrics. The simulation process includes two main steps: firstly the rigid object simulation and secondly the flexible mass simulation near to be equilibrium. A multiresolution modeling is applied to enhance the tradeoff fruit of the realistic presentation and computation cost. Finally, some examples and the analysis results show the efficiency of the proposed method.

    2010-01-01

    This study investigated the effects of clothing fabric on human skin microcirculation. Once skin is covered with a clothing fabric, human sensations, namely, coolness, warmth, softness, and roughness, are amused immediately, and the cutaneous micrecireulation may be changed consequently. Since the complex relationships of the human skin, the environment, and the clothing, there is few publication focusing on the physiological responses of the skin to the fabrics. In this paper, a Laser Doppler Flowmetry (LDF) was used to test the dynamic responses of the skin blood flow when the fabric was placed on the skin. Effects of different fabrics on the skin blood flux were investigated. The results show that cold stimulation of fabric has remarkable influences on the skin blood flux, and the surface properties of fabric are of importance to affect the human skin blood flow.

  9. Heat Pump Clothes Dryer Model Development

    Energy Technology Data Exchange (ETDEWEB)

    Shen, Bo [ORNL

    2016-01-01

    A heat pump clothes dryer (HPCD) is an innovative appliance that uses a vapor compression system to dry clothes. Air circulates in a closed loop through the drum, so no vent is required. The condenser heats air to evaporate moisture out of the clothes, and the evaporator condenses water out of the air stream. As a result, the HPCD can achieve 50% energy savings compared to a conventional electric resistance dryer. We developed a physics-based, quasi-steady-state HPCD system model with detailed heat exchanger and compressor models. In a novel approach, we applied a heat and mass transfer effectiveness model to simulate the drying process of the clothes load in the drum. The system model is able to simulate the inherently transient HPCD drying process, to size components, and to reveal trends in key variables (e.g. compressor discharge temperature, power consumption, required drying time, etc.) The system model was calibrated using experimental data on a prototype HPCD. In the paper, the modeling method is introduced, and the model predictions are compared with experimental data measured on a prototype HPCD.

  12. INNOVATIVE CLOTHING DESIGN FOR WOMEN DURING PREGNANCY

    Directory of Open Access Journals (Sweden)

    POPESCU Georgeta

    2015-05-01

    Full Text Available During pregnancy there is an evident change in the physical appearance of a woman's body. The most evident change is the substantial weight gain, increased abdominal region, torso and hip, and limbs thickening. Physical changes leads to the need of a wardrobe changing, especially in the fourth month of pregnancy. Given these factors the question arises is to identify the transformations of body conformation and ensure a maximum comfort in developing clothing products for this category. Because it is a continuous transformation, the products must be designed to be adjustable and versatile, ensuring their usability for a long period of the pregnancy and even after birth. The paper presents the specific algorithms for body conformations during pregnancy and the patterns designed based on these algorithms with the proper modifications. The principle of designing clothes for pregnant women refers to the introduction of pregnancy-related size changes in the standard method of pattern design. The research was conducted by INCDTP during the initial stage of a project, financed through national founds, consisting in a documentary study on morphologic indicators of women during the pregnancy period, the changes observe and their application in pattern design. Following the principles specific to the product group studied regarding comfort and style, INCDTP specialists have developed and produced a collection of clothing products for women during pregnancy.

    2015-12-01

    The evaluative approach is a logical approach to interpreting scientific findings in criminal cases, applying knowledge regarding the transfer, persistence and recovery of particulate material. The application of this approach to interpreting the finding of gunshot residue on the clothing of a suspect requires knowledge of background levels of GSR on clothing and on the frequency of different residue types in a particular environment. The cuffs of 100 upper outer garments submitted to a forensic laboratory in connection with non-firearms offences were sampled for gunshot residue. No 3-component lead/antimony/barium particles were found on 98 of them. Two 3-component particles were found on one of them and one 3-component particle was found on another. The frequency of occurrence of various particle types regarded as consistent with GSR was also explored. The findings show that, while 3-component particles were somewhat more likely to be encountered by chance on clothing than on hands, they are still relatively uncommon events. To investigate the frequency of occurrence of particular residue types, 100 discharged rounds of ammunition recovered at crime scenes were sampled and the types of residue present were determined. The results show that some residue types are significantly more common than others. Both sets of data will be of value in evaluating the significance of finding GSR on clothing of suspects in criminal cases.

    Full Text Available “Visual perception” is in the first ranking between the types of perception. Gestalt Theory of the major psychological theories are used in how visual perception realizes and making sense of what is effective in this process. In perception stage brain tak es into account not only stimulus from eyes but also expectations arising from previous experience and interpreted the stimulus which are not exist in the real world as if they were there. Misperception interpretations that brain revealed are called as “Pe rception Illusion” or “Optical Illusion” in psychology. Optical illusion formats come into existence due to factors such as brightness, contrast, motion, geometry and perspective, interpretation of three - dimensional images, cognitive status and color. Opti cal illusions have impacts of different disciplines within the study area on people. Among the most important types of known optical illusion are Oppel - Kundt, Curvature - Hering, Helzholtz Sqaure, Hermann Grid, Muller - Lyler, Ebbinghaus and Ponzo illusion etc . In fact, all the optical illusions are known to be used in numerous area with various techniques and different product groups like architecture, fine arts, textiles and fashion design from of old. In recent years, optical illusion types are frequently us ed especially within the field of fashion design in the clothing model, in style, silhouette and fabrics. The aim of this study is to examine the clothing design applications where optical illusion is used and works done in this subject. Some research of the design with the changing fashion of clothes of different types of optical illusions is discussed with examples of their effects on visual perception. In the study, optical illusory clothing models are scanned by visual analysis from documents like film , video, picture, web pages. The findings were analyzed in terms of the surface and design and effects of the optical illusion on clothing design has tried to put

    The first hygroscopically tunable cloth actuator is realized via impregnation of a commercial cloth template by a three dimensionally (3D) nanoporous polymer/carbon nanotube hybrid network. The nanoporous hybrid guarantees diffusion of water into the cloth actuator and amplifies the deformation scale. The cloth actuators are mechanically stable with high tensile strength. Because the commercial cotton cloth is inexpensive, such actuators capable of complex motions can be produced in a large size and scale for a wide variety of utilities (e.g. electric generators and "smart" materials).

  1. The Progress of the Clothing for Cold Weather

    Science.gov (United States)

    Yasuda, Takeshi; Ijiri, Tokiko

    The clothing for cold weather were discused. The total insulation in man is made up of sum of the insulation afforded by clothes, air and tissues. A function of clothing is to protect the body from the environment, this is especially true when himalayan expedition. Many expedition to the himalayan high altitude have had useful experiences in the textile and clothing field. Historical development and fundamental matters of clothing for himalayan expedition were explained. The insulating properties of a fabric are due not to the fibers of the fabric itseif, but to the air trapped with in the fabric. it is impotant to realise that the thermal insulation of clothing is proportional to the thickness of the dead space air trapped within the clothing. Down clothes are extremely warm, light and comfortable. A windproof outer layer is necessary to prevent penetration by external air. If air penetrates, clothing the trapped dead air is moved and insu1ation will diminish. Overheating when exercising in the cold with loss of insulation associated with the production of sweat, and thus of darnp clothing, is a well recognized hazard. It was considered that we must make every effort to be as safe as possible in clothing science field for cold environment.

    2007-05-01

    Garment fit and resultant air volume is a crucial factor in thermal insulation, and yet, it has been difficult to quantify the air volume of clothing microclimate and relate it to the thermal insulation value just using the information on the size of clothing pattern without actual 3D volume measurement in wear condition. As earlier methods for the computation of air volume in clothing microclimate, vacuum over suit and circumference model have been used. However, these methods have inevitable disadvantages in terms of cost or accuracy due to the limitations of measurement equipment. In this paper, the phase-shifting moiré topography was introduced as one of the 3D scanning tools to measure the air volume of clothing microclimate quantitatively. The purpose of this research is to adopt a non-contact image scanning technology, phase-shifting moiré topography, to ascertain relationship between air volume and insulation value of layered clothing systems in wear situations where the 2D fabric creates new conditions in 3D spaces. The insulation of vests over shirts as a layered clothing system was measured with a thermal manikin in the environmental condition of 20 degrees C, 65% RH and air velocity of 0.79 m/s. As the pattern size increased, the insulation of the clothing system was increased. But beyond a certain limit, the insulation started to decrease due to convection and ventilation, which is more apparent when only the vest was worn over the torso of manikin. The relationship between clothing air volume and insulation was difficult to predict with a single vest due to the extreme openings which induced active ventilation. But when the vest was worn over the shirt, the effects of thickness of the fabrics on insulation were less pronounced compared with that of air volume. In conclusion, phase-shifting moiré topography was one of the efficient and accurate ways of quantifying air volume and its distribution across the clothing microclimate. It is also noted

    Full Text Available When it is examined, it is obvious that clothing has had different phases from old periods up to now. People have created clothings in accordance with their civilization level and any nation has formed its own clothes according to its customs, rituals beliefs and life styles. By this forms, any nation has created its own clothings. While clothing has been formed by t he effect of natural environment, traditional clothing has been formed according to social features. In the formation of these clothings, natural environment has not had an direct effect; yet, they are evaluated in their geographical regions and vicinities , because there are the same sociological, psychological and historical formations. People living in Anatolia have tried to make their clothes much more ostentatious and useful. And they have displayed admirable ornamentations on their clothes. It is possi ble to see that on traditional clothings. Clothing which has a big importance differs from city to city and even from town to town. This study is done on the pupose of analysing, fixating and finding out the clothes whose usage disappear swiftly but exist only in weddings, chests and doweries with regards to reveal the clothing culture and the understanding of art which takes form on this culture in Tavas, Denizli. This study is done by the purpose of analysing the traditional Turkish woman clothings that are don (şalvar, göynek, üç etek, cepken, tel kırma(bürgü, krep, kuşak, peştamalin which belong to Tavas, Denizli region in terms of material, cut, sewing and ornamentation features; and providing evidence in the direction of science discipline.

  4. Altered Images: the relations between design representation and design practice

    Full Text Available As information systems move out of the office into the wider world and are merged with mobile appliances, buildings and even clothing, the representations traditionally used in any one discipline may not be adequate for understanding these new domains. Design representations are ‘ways of seeing and not seeing’. Despite the central role representations play in design, the information systems design community has little understanding of the relation, ideal or actual, between design practice and design representation. This paper reports on an extensive design case study that aims at increasing understanding of the nature and affordances of representations in the design process and argues for the need for information systems as a discipline to open up discussion of the design representations that may be required to effectively design systems that mix traditional IS with disciplines such as industrial design, architecture and fashion design.

  5. Quiver representations

    Schiffler, Ralf

    2014-01-01

    This book is intended to serve as a textbook for a course in Representation Theory of Algebras at the beginning graduate level. The text has two parts. In Part I, the theory is studied in an elementary way using quivers and their representations. This is a very hands-on approach and requires only basic knowledge of linear algebra. The main tool for describing the representation theory of a finite-dimensional algebra is its Auslander-Reiten quiver, and the text introduces these quivers as early as possible. Part II then uses the language of algebras and modules to build on the material developed before. The equivalence of the two approaches is proved in the text. The last chapter gives a proof of Gabriel’s Theorem. The language of category theory is developed along the way as needed.

    Stereotypic presumptions about gender affect the design process, both in relation to how users are understood and how products are designed. As a way to decrease the influence of stereotypic presumptions in design process, we propose not to disregard the aspect of gender in the design process......, as the perspective brings valuable insights on different approaches to technology, but instead to view gender through a value lens. Contributing to this perspective, we have developed Value Representations as a design-oriented instrument for staging a reflective dialogue with users. Value Representations...

  8. Integrated human-clothing system model for estimating the effect of walking on clothing insulation

    The objective of this work is to develop a 1-D transient heat and mass transfer model of a walking clothed human to predict the dynamic clothing dry heat insulation values and vapor resistances. Developing an integrated model of human and clothing system under periodic ventilation requires estimation of the heat and mass transfer film coefficients at the skin to the air layer subject to oscillating normal flow. Experiments were conducted in an environmental chamber under controlled conditions of 25 C and 50% relative humidity to measure the mass transfer coefficient at the skin to the air layer separating the wet skin and the fabric. A 1-D mathematical model is developed to simulate the dynamic thermal behavior of clothing and its interaction with the human thermoregulation system under walking conditions. A modification of Gagge's two-node model is used to simulate the human physiological regulatory responses. The human model is coupled to a clothing three-node model of the fabric that takes into consideration the adsorption of water vapor in the fibers during the periodic ventilation of the fabric by the air motion in from ambient environment and out from the air layer adjacent to the moist skin. When physical activity and ambient conditions are specified, the integrated model of human-clothing can predict the thermo-regulatory responses of the body together with the temperature and insulation values of the fabric. The developed model is used to predict the periodic ventilation flow rate in and out of the fabric, the periodic fabric regain, the fabric temperature, the air layer temperature, the heat loss or gain from the skin, and dry and vapor resistances of the clothing. The heat loss from the skin increases with the increase of the frequency of ventilation and with the increased metabolic rate of the body. In addition, the dry resistance of the clothing fabrics, predicted by the current model, IS compared with published experimental data. The current

    The Chaussez Capote Project interviewed 48 youths in Abidjan and Dabou aged 14-25 years on how to best get individuals in their age group to use condoms. 251 individuals aged 15-25 were also surveyed in Abidjan on the same subject. While more than 80% of this latter group had already discussed AIDS, sexually transmitted disease (STD), and prevention with others, 90% still wanted advice on these themes from medical staff and the media. 40% who had already used condoms did so incorrectly, while approximately 33% had experienced condom breakage during use. Respondents felt that condom promotion should be associated with information on AIDS, STDs, and contraception or information on general health. In response to this feedback, the project commissioned the creation of a promotional music cassette with French and African songs of different musical styles. Lyrics imparted technical information and correct misconceptions related to condom use. Free distribution of the cassette commenced August 1992, and approximately 800 were given to organizations and businesses. The cassette also aired on radio and Ivorian television, but met with only limited success. It is thought that its impact was limited due to the small number of copies duplicated and inefficient distribution. A new version was therefore created with different songs and short messages by popular African singers for local duplication and sale at a subsidized price starting December 1993. As a 2nd intervention, clothing metaphors applied to condoms and condom use were applied to the development of a clothing promotion loincloth designed Spring 1993. The cloth was pretested and revised to ultimately consist of panels depicting 2 young couples, a condom, a panther, and the words Entre nous. The cloth has been ordered for use by the National AIDS Committee, a condom social marketing project, and the French agency for development cooperation.

    During acts of physical aggression, offenders frequently come into contact with clothes of the victim, thereby leaving traces of DNA-bearing biological material on the garments. Since tape-lifting and swabbing, the currently established methods for non-destructive trace DNA sampling from clothing, both have their shortcomings in collection efficiency and handling, we thought about a new collection method for these challenging samples. Testing two readily available electrostatic devices for their potential to sample biological material from garments made of different fabrics, we found one of them, the electrostatic dust print lifter (DPL), to perform comparable to well-established sampling with wet cotton swabs. In simulated aggression scenarios, we had the same success rate for the establishment of single aggressor profiles, suitable for database submission, with both the DPL and wet swabbing. However, we lost a substantial amount of information with electrostatic sampling, since almost no mixed aggressor-victim profiles suitable for database entry could be established, compared to conventional swabbing. This study serves as a proof of principle for electrostatic DNA sampling from items of clothing. The technique still requires optimization before it might be used in real casework. But we are confident that in the future it could be an efficient and convenient contribution to the toolbox of forensic practitioners.

    Full Text Available It is known that Turks who have a rich culture and an old and well - known civilization have a unique clothing style. The clothing of Turks varies according to the geographical regions, living styles, social differences and gender along the periods they lived. Clothing is one of the most important needs in life depending on the individual and social attributes. The clothing which first emerged as protection means is a social fact complementing the physical and psychological existence of human being, changing forms depending on technological developments and phases, and continuously changing under the affect of fashion today. Clothing is an aesthetic value fed by the feelings of individuals. So, clothing has an indispensable place in the structure and communication of cultural and social identity within this direction. The costumes of traditional Turkish Anatolian women reflect thoughts an d feelings When Turkish Nation’s long history and the cultures that it had interacted are thought, it’s seen that the glory and magnificence it had has also reflected in it’s clothing culture. Traditional clothing of Malatya region has a special character istic. However, these clothes are dissappearing day by day, With the present study, we aimed to protect our cultural heritage and carry these clothes to the present via current designs. This study identified and the traditional dresses fabric , patterns and motifs are made by making use of designs suitable to the present day fashion .

    2012-03-01

    Full Text Available We present experimental results related to the manufacturing of phantoms based on polyvinyl-alcohol (PVA mixed with SiO2, graphite and Ag nanoparticles. These phantoms are dummy representations of the human tissue of the breast gland. We focus our attention on the representation of the optical and the mechanical properties of the actual biological healthy tissue and of that representing a hidden cancer tumor (lesion. The quality of the samples is tested by ultrasonic imaging and laser induced photothermal (PT detection technique. From the former test, the mechanical contrast that one can achieve is apparent. Instead, the laser detection technique makes it possible to determine that the optical contrast is achievable. For the laser induced PT method we register the so-called photothermal amplitudes, rather known as photoacoustic (PA signals. These are the ultimate expression of laser-induced bursts of photothermal processes, whose engine is the fraction of the optically absorbed energy that decays through nonradiative channels. In our case we look for the conditions at which the PT phenomena are produced by a hidden dummy-tumor alone; meaning that the output signals are nearly free from substantial contributions from the bulk of the phantom. This is so as to mimic the actual mechanical and optical absorption erformance of breast tissue with an inner cancer tumor. From the ultrasound images one can see how apparent the resemblance with the actual human tissue is.

  15. Optimizing the protection against the physiological burden of CBRN clothing.

    2010-01-01

    Soldiers can wear chemical, biological, radiological and nuclear (CBRN) protective clothing to be protected against warfare agents. The disadvantage of that clothing is that higher protection introduces higher physiological burden. Therefore an optimum between comfort and protection must be found. Models of all relevant processes were created to find this optimum. The airflow profile around a cylinder with clothing-representing a dressed human body part-was modelled. This flow profile was used for calculating the agent vapour breakthrough through the clothing and for calculating the deposition of agents onto the skin (as indicators for protection). The flow profile was also used for calculating the temperature profile around the body part and the relative humidity underneath and in the clothing (as representative for physiological burden). As a result a tool was created, which can be used to identify the optimum properties of CBRN protective clothing, depending on the intended mission of the soldiers.

    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.

    2013-01-01

    The simulation of cloth with rich folds and wrinkles is a computationally expensive process. In this paper, we introduce an example-based algorithm for fast animation of plausible cloth wrinkles. Our algorithm does not depend on a character's pose, therefore it is valid for loose dresses, curtains, etc., not just cloth defined by skinning techniques. Central to our approach is a correspondence between low and high-resolution cloth deformations, both at the training and synthesis stages. Based on this correspondence, we define an algorithm for synthesizing cloth wrinkles as a function of the deformation of a low-resolution cloth and a set of example poses. We demonstrate the animation of plausible high-resolution wrinkles at high frame rates, suitable for interactive applications such as video games.

    Full Text Available This study was designed to profile the mature female clothing shopper. More specifically certain variables that could be attributed to differences in consumer behaviour were investigated. Mature female clothing shoppers were segmented as clothing moderates, clothing enthusiasts and the clothing unconcerned. These three cluster groups significantly differed regarding clothing involvement, clothing orientation, activities, interests, opinions, family orientation, needs and media usage. No significant differences were found among the three groups regarding evaluative criteria for clothing and clothing store attributes. Profiles of the clusters were developed, along with applicable marketing implications. Recommendations for further research are made.

  2. Estimating Clothing Thermal Insulation Using an Infrared Camera

    Directory of Open Access Journals (Sweden)

    Jeong-Hoon Lee

    2016-03-01

    Full Text Available In this paper, a novel algorithm for estimating clothing insulation is proposed to assess thermal comfort, based on the non-contact and real-time measurements of the face and clothing temperatures by an infrared camera. The proposed method can accurately measure the clothing insulation of various garments under different clothing fit and sitting postures. The proposed estimation method is investigated to be effective to measure its clothing insulation significantly in different seasonal clothing conditions using a paired t-test in 99% confidence interval. Temperatures simulated with the proposed estimated insulation value show closer to the values of actual temperature than those with individual clothing insulation values. Upper clothing’s temperature is more accurate within 3% error and lower clothing’s temperature is more accurate by 3.7%~6.2% error in indoor working scenarios. The proposed algorithm can reflect the effect of air layer which makes insulation different in the calculation to estimate clothing insulation using the temperature of the face and clothing. In future, the proposed method is expected to be applied to evaluate the customized passenger comfort effectively.

  3. Development of Protective Clothing against Nanoparticle Based on Electrospun Nanofibers

    2012-01-01

    Full Text Available In this paper, the development of efficient protective clothing against nanoparticulate aerosols is presented. Nanofibrous mats of polyamide 6 (PA6 were deposited onto a nonwoven viscose substrate by electrospinning technique. The influence of electrospinning parameters, including solution concentration, viscosity, and conductivity, was studied for the production of nonwovens with controlled fiber diameter showing a size distribution ranging from 66 to 195 nm. By varying several process parameters, textiles with different thickness of the nanofiber layer and thus air permeability were obtained. A hot-press lamination process using a thermoplastic resin as glue was applied to improve the adhesion of the nanofiber layer onto the textile support. After 1500 cycles of repeated compression and torsion, the nanofiber layer was still firmly attached to the support, while mechanical damage is visible in some areas. The penetration of NaCl particles with diameter ranging from 15 to 300 nm through the electrospun textiles was found to be strongly dependent on nanofiber layer thickness. A really thin nanofiber coating provides up to 80% retention of 20 nm size particles and over 50% retention of 200 nm size nanoparticles. Increasing the thickness of the nanofiber mat, the filtration efficiency was increased to over 99% along the whole nanoparticle range. The results obtained highlight the potential of nanofibers in the development of efficient personal protective equipments against nanoparticles.

These development efforts were independent of one another and are presented in this report in two separate volumes. Volume 1 details the Heat Pump Dryer Development while Volume 2 details the Modulating Gas Dryer Development. In both product development efforts, the intent was to develop high efficiency, high performance designs that would be attractive to US consumers. Working with Whirlpool Corporation as our commercial partner, TIAX applied this approach of satisfying consumer needs throughout the Product Development Process for both dryer designs. Heat pump clothes dryers have been in existence for years, especially in Europe, but have not been able to penetrate the market. This has been especially true in the US market where no volume production heat pump dryers are available. The issue has typically been around two key areas: cost and performance. Cost is a given in that a heat pump clothes dryer has numerous additional components associated with it. While heat pump dryers have been able to achieve significant energy savings compared to standard electric resistance dryers (over 50% in some cases), designs to date have been hampered by excessively long dry times, a major market driver in the US. The development work done on the heat pump dryer over the course of this program led to a demonstration dryer that delivered the following performance characteristics: (1) 40-50% energy savings on large loads with 35 F lower fabric temperatures and similar dry times; (2) 10-30 F reduction in fabric temperature for delicate loads with up to 50% energy savings and 30-40% time savings; (3) Improved fabric temperature uniformity; and (4) Robust performance across a range of vent restrictions. For the gas dryer development, the concept developed was one of modulating the gas flow to the dryer throughout the dry cycle. Through heat modulation in a

    Two kinds of humidity-induced, bendable smart clothing have been designed to reversibly adapt their thermal insulation functionality. The first design mimics the pores in human skin, in which pre-cut flaps open to produce pores in Nafion sheets when humidity increases, as might occur during human sweating thus permitting air flow and reducing both the humidity level and the apparent temperature. Like the smart human sweating pores, the flaps can close automatically after the perspiration to keep the wearer warm. The second design involves thickness adjustable clothes by inserting the bent polymer sheets between two fabrics. As the humidity increases, the sheets become thinner, thus reducing the gap between the two fabrics to reduce the thermal insulation. The insulation layer can recover its original thickness upon humidity reduction to restore its warmth-preservation function. Such humidity sensitive smart polymer materials can be utilized to adjust personal comfort, and be effective in reducing energy consumption for building heating or cooling with numerous smart design.

    Full Text Available Assembly lines take the attention of researchers and companies because of its great effect on efficiency. Efficiency in assembly lines has an important role on cost and quality which are the basic fundamentals of competition. Assembly lines contain a number of workstations and tasks (jobs are processed in these stations and are moved from station to station. The tasks are assigned to each station regarding a cycle time. The cycle time is the maximum available time for the production of a job at any workstation. The assingning of jobs to workstations is based on the objective of minimizing the workflow among the workstations, reducing the throughput time as well as the work in progress and thus increasing productivity. If the jobs are not allocated in balance, this will cause idle workstations and waste of workforce besides the loss of overall efficiency. In this study, an assebly line balancing problem was examined for a five pocket denim trousers in a clothing company. Firstly, priority associations and standard durations of operations of denim trousers were determined. Then, assembly line balancing study was carried out by using ranked positional weights assembly line balancing method developed by Helgeson and Birnie to increase the production in a clothing company manufacturing five pocket denim trousers.

    All human space missions require significant logistical mass and volume that will become an excessive burden for long duration missions beyond low Earth orbit. The current International Space Station (ISS) crew wardrobe has already evolved not only to reduce some of the logistical burden but also to address crew preference. The present study was undertaken to find ways further to reduce this logistical burden while examining human response to different types of clothes. The primary objective of the study is to measure how long people can wear the same exercise garment, depending on the type of fabric and the presence of antimicrobial treatment. The secondary objective is to assess the reasons for length of wear from perceptions of clothing characteristics, including nine ordinal scales. Cardiovascular exercise was chosen as the activity in this experiment for its profuse sweating effect and because it is considered a more severe treatment applied to the clothes than every-day usage. Study garments were exercise T-shirts and shorts purchased from various vendors. Fabric construction, fabric composition, and finishing treatment were defined as the key variables. A web-based questionnaire was used for self-reported data collection. The study was divided in three balanced experiments: a cotton-polyester-wool (CPW) T-shirts study with 61 participants, a polyester-modacrylic-polyester/cocona (PMC) T-shirts study with 40 participants, and a shorts study with 70 participants. In the CPW study, the T-shirts were made of 100% cotton, or of 100% polyester or of 100% wool, and categorized into open and tight knit constructions. In the PMC study, the T-shirts were made of 100% polyester, or of 82% modacrylic, or of 95% polyester with 5% cocona fiber, without construction distinction. The shorts were made either of 100% cotton or of 100% polyester, and were knitted or woven. Some garments were treated with Bio-Protect 500 antimicrobial finish according the experimental design

  13. Simple quantum systems in the momentum representation

    Núñez-Yépez, H N; Martínez y Romero, R P; Salas-Brito, A L

    2000-01-01

    The momentum representation is seldom used in quantum mechanics courses. Some students are thence surprised by the change in viewpoint when, in doing advanced work, they have to use the momentum rather than the coordinate representation. In this work, we give an introduction to quantum mechanics in momentum space, where the Schrödinger equation becomes an integral equation. To this end we discuss standard problems, namely, the free particle, the quantum motion under a constant potential, a particle interacting with a potential step, and the motion of a particle under a harmonic potential. What is not so standard is that they are all conceived from momentum space and hence they, with the exception of the free particle, are not equivalent to the coordinate space ones with the same names. All the problems are solved within the momentum representation making no reference to the systems they correspond to in the coordinate representation.

    2016-01-01

    It is unknown whether allowing patients to have BMD (bone mineral density) studies acquired while wearing radiolucent clothing adlib contributes appreciably to the measurement error seen. To examine this question, a spine phantom was scanned 30 times without any clothing, while draped with a gown, and while draped with heavy winter clothing. The effect on mean BMD and on SD (standard deviation) was assessed. The effect of clothing on mean or SD of the area was not significant. The effect of clothing on mean and SD for BMD was small but significant and was around 1.6% for the mean. However, the effect on BMD precision was much more clinically important. Without clothing the spine phantom had an least significant change of 0.0077 gm/cm(2), while when introducing variability of clothing the least significant change rose as high as 0.0305 gm/cm(2). We conclude that, adding clothing to the spine phantom had a small but statistically significant effect on the mean BMD and on variance of the measurement. It is unlikely that the effect on mean BMD has any clinical significance, but the effect on the reproducibility (precision) of the result is likely clinically significant.

    This project was successful in demonstrating the feasibility of a step change in residential clothes dryer energy efficiency by demonstrating heat pump technology capable of 50% energy savings over conventional standard-size electric dryers with comparable drying times. A prototype system was designed from off-the-shelf components that can meet the project’s efficiency goals and are affordable. An experimental prototype system was built based on the design that reached 50% energy savings. Improvements have been identified that will reduce drying times of over 60 minutes to reach the goal of 40 minutes. Nevertheless, the prototype represents a step change in efficiency over heat pump dryers recently introduced to the U.S. market, with 30% improvement in energy efficiency at comparable drying times.

    Herein, we demonstrate that a flexible, air-permeable, thermoelectric (TE) power generator can be prepared by applying a TE polymer (e.g. poly(3,4-ethylenedioxythiophene):poly(4-styrenesulfonate)) coated commercial fabric and subsequently by linking the coated strips with a conductive connection (e.g. using fine metal wires). The poly(3,4-ethylenedioxythiophene):poly(4-styrenesulfonate) coated fabric shows very stable TE properties from 300 K to 390 K. The fabric device can generate a TE voltage output (V) of 4.3 mV at a temperature difference (ΔT) of 75.2 K. The potential for using fabric TE devices to harvest body temperature energy has been discussed. Fabric-based TE devices may be useful for the development of new power generating clothing and self-powered wearable electronics.

  10. Bern clothes washer study. Final report

    Energy Technology Data Exchange (ETDEWEB)

    Tomlinson, J.J.; Rizy, D.T.

    1998-03-01

    The US market for domestic clothes washers is currently dominated by conventional, vertical axis washers, which typically require about 40 gallons of water for each load. Although small for an individual load, the fact that 35 billion loads of laundry are washed annually in the US results in a substantial quantity of water and energy use. Although much smaller, today`s market for high-efficiency clothes washers which use much less water and energy is growing albeit slowly as manufacturers are making washers based around tumble-action, horizontal axis designs available, information about their performance and benefits is being developed, and consumers are made aware of these benefits. To help build awareness of these benefits and to accelerate markets for high-efficiency washers, DOE, under its Energy Star Program and in cooperation with Maytag Appliances, conducted a field-evaluation of high-efficiency washers using Bern, Kansas (population approximately 200) as a test bed. Baseline washer performance data as well as customer washing behavior were obtained from data collected on the existing washers of more than 100 participants in this instrumented study. Following a 2-month initial study period, all conventional washers were replaced by high-efficiency, tumble action washers, and the experiment continued for another 3-month period. Based on measured data from over 20,000 loads of laundry, the impact of the washer replacement on (1) individual customers` energy and water consumption, (2) customers` laundry habits and perceptions, and (3) the community`s water supply and waste water systems were determined and reported.

    A cloth simulation represents the behavior of cloth objects such as flag, tablecloth, or even garments has application in clothing animation for games and virtual shops. Elastically deformable models have widely used to provide realistic and efficient simulation, however problem of overstretching is encountered. We introduce a new cloth simulation algorithm that replaces iterative distance constraint enforcement steps with non-iterative ones for preventing over stretching in a spring-mass system for cloth modeling. Our method is based on a simple position correction procedure applied at one end of a spring. In our experiments, we developed a rectangle cloth model which is initially at a horizontal position with one point is fixed, and it is allowed to drape by its own weight. Our simulation is able to achieve a plausible cloth drapes as in reality. This paper aims to demonstrate the reliability of our approach to overcome overstretches while decreasing the computational cost of the constraint enforcement process due to an iterative procedure that is eliminated.

    Wearing behavior and thermoregulatory responses of five young women (YG; 20 +/- 1 yr) and five aged women (AG; 65 +/- 3 yr) to indoor cold in summer were investigated in this study. The subjects were exposed to 21.0 +/- 0.5 degrees C and 55 +/- 5% RH while seated during a 90-minute experiment. The subjects were allowed to select and wear for thermal comfort clothing whenever they needed additional clothing during the experiment. Rectal temperature (Tre) and temperatures of 7 sites (head, chest, forearm, hand, thigh, leg, foot) of the skin of the subjects were measured every 10 minutes. Mean skin temperature (Tsk) of the subject was obtained every 10 minutes. First selection time of additional clothing was monitored and weight of selected total clothing was calculated. The results for this study were as follows: Tre and Tsk gradually decreased in YG and AG, however Tre decreased less than Tsk which decreased greater in AG than YG (p clothing and thermal sensation response were slower than YG's. Furthermore, total clothing weight was less in AG than YG. It was concluded that clothing selection behavior would modify the intrinsic thermoregulatory responses of the aged women to the cold stress in the summer.

    Commonly, marker based as well as markerless motion capture systems assume that the tracked person is wearing tightly fitting clothes. Unfortunately, this restriction cannot be satisfied in many situations and most preexisting video data does not adhere to it either. In this work we propose a graphics based vision approach for tracking humans markerlessly without making this assumption. Instead, a physically based simulation of the clothing the tracked person is wearing is used to guide the tracking algorithm.

    Background Paper mulberry has been used for thousands of years in Asia and Oceania for making paper and bark-cloth, respectively. Museums around the world hold valuable collections of Polynesian bark-cloth. Genetic analysis of the plant fibers from which the textiles were made may answer a number of questions of interest related to provenance, authenticity or species used in the manufacture of these textiles. Recovery of nucleic acids from paper mulberry bark-cloth has not been reported before. Methodology We describe a simple method for the extraction of PCR-amplifiable DNA from small samples of contemporary Polynesian bark-cloth (tapa) using two types of nuclear markers. We report the amplification of about 300 bp sequences of the ITS1 region and of a microsatellite marker. Conclusions Sufficient DNA was retrieved from all bark-cloth samples to permit successful PCR amplification. This method shows a means of obtaining useful genetic information from modern bark-cloth samples and opens perspectives for the analyses of small fragments derived from ethnographic materials.

    Ramie cloth/UP resin composite was formed at 0.2 MPa and cured at room temperature for 24 h and treated at 80 ℃ for2 h. The physical and mechanical properties of the composites with different volume fractions of ramie cloth were studied. The results show that,with the increase of the volume fraction of the ramie cloth,densities of the composites become greater and greater,though all lower than the theoretical values,the linear shrinkage during the formation decreases from 1.20% of the original UP resin to 0.18% of the composite with 30% of ramie cloth in volume,all the composites also absorb more water than UP resin casting,greater volume fraction of the fiber,more water will be absorbed,but the increase in water absorption becomes smaller and smaller with time. As regards some mechanical properties,the tensile strength,flexural strength,flexural modulus and impact strength are all improved when more ramie fiber is added. Compared with those of pure UP resin casting,the mechanical properties are increased by 93.93%,76.20%,190.18% and 227.26% respectively when the volume fraction of the ramie cloth in the composite is 30%. The differential scanning calorimetry results show that only one peak will appear for the sample without or with less ramie fiber while two peaks will appear when more ramie cloth is added.

    This study was conducted to improve the construction of impermeable clothing protecting against liquid chemical agents in order to lower the thermal strain caused by the clothing during work. Previous studies indicated that light work in a hot environment in this kind of clothing could last 30 min only. We propose a modification of the construction; new models of protective clothing were tested in wear trials. Then the results were compared with a basic model of impermeable protective clothing. Results indicated that all new models of protective clothing allowed workers to work 39-64% longer than in a basic model of protective clothing. Thus new clothing significantly improved comfort of work in impermeable protective clothing because of the lower thermal strain that it imposed on the user.

    Comparatively few studies have been carried out on air weapon injuries yet there are significant number of injuries and fatalities caused by these low power weapons because of their availability and the public perception that because they need no licence they are assumed to be safe. In this study ballistic gel was tested by Bloom and rupture tests to check on consistency of production. Two series of tests were carried out firing into unclothed gel blocks and blocks loosely covered by different items of clothing to simulate attire (tee shirt, jeans, fleece, and jacket). The damage to the clothing caused by different shaped pellets when fired at different ranges was examined. The apparent hole size was affected by the shape of pellet (round, pointed, flat and hollow point) and whether damage was predominantly caused by pushing yarn to one side or by laceration of the yarn through cutting or tearing. The study also compared penetration into clothed gel and unclothed gel under identical conditions, and loose clothing greatly reduced penetration. With loose clothing at 9.1 m range clothing reduced penetration to 50-70% of the penetration of unclothed gel but at 18.3m range only 7 out of 36 shots penetrated the gel. This cannot be accounted for by the energy loss at the longer range (3-7% reduction from 9.1 m to 18.3 m range in unclothed gels) and it is suggested that impulse may have a role to play. Shots that did not penetrate the gel were used to estimate the possible stopping time for the pellet (around 75 μs) and force (1700 N) or stress (100 MPa) required to bring the pellet to a halt. Even with these low energy projectiles, cloth fibres were entrained in the gel showing the potential for penetration of the body and subsequent infection. Copyright © 2014 Elsevier Ireland Ltd.

    Full Text Available As part of the Europeana Cloud (eCloud project, Trinity College Dublin investigated best practice in the use of web services, such as APIs, for accessing large data sets from cultural heritage collections. This research looked into the provision and use of APIs, and moreover, whether or not more customised programmatic access to datasets is what researchers want or need. In order to understand whether current patterns of API usage reflect a skills gap on the part of researchers or a mismatch of tool to purpose, we looked not only at the creators and developer/users of APIs, but also at humanists already re-using big data; approaches in cultural heritage institutions and other research infrastructures to bring API use to non-technical audiences; and the kinds of training and other support services available or emerging within the data-intensive humanities research lifecycle. We conducted both desk research and a series of 11 interviews with figures working as researchers, developers or data providers, including figures from both the API development and the data usage communities. This research, conducted under the eCloud project and supported by the European Commission’s ICT Policy and Support Programme (Grant number 325091, was begun in March 2014 and is now in its concluding validation stage. The results of the research are not yet finalised, but the contribution is already emerging of this work to the debate about APIs being either the way forward for digital cultural heritage collections, or the Emperor’s New Clothes (or maybe a bit of both.

    Due to their potential toxicity, the use of nanoparticles in the workplace is a growing concern. Some studies indicate that nanoparticles can penetrate the skin and lead to adverse health effects. Since chemical protective clothing is the last barrier to protect the skin, this study aims to better understand nanoparticle penetration behaviour in dermal protective clothing under mechanical deformation. For this purpose, five of the most common types of fabrics used in protective clothing, one woven and four nonwoven, were chosen and submitted to different simulated exposure conditions. They were tested against polydispersed NaCl aerosols having an electrical-mobility diameter between 14 and 400 nm. A bench-scale exposure setup and a sampling protocol was developed to measure the level of penetration of the aerosols through the material samples of disposable coveralls and lab coat, while subjecting them to mechanical deformations to simulate the conditions of usage in the workplace. Particle size distribution of the aerosol was determined upstream and downstream using a scanning mobility particle sizer (SMPS). The measured efficiencies demonstrated that the performances of nonwoven materials were similar. Three nonwovens had efficiencies above 99%, while the woven fabric was by far, the least effective. Moreover, the results established that mechanical deformations, as simulated for this study, did not have a significant effect on the fabrics' efficiencies.

    The thermal insulation of clothing is one of the most important parameters used in the thermal comfort model adopted by the International Standards Organisation (ISO) [BS EN ISO 7730, 2005. Ergonomics of the thermal environment. Analytical determination and interpretation of thermal comfort using calculation of the PMV and PPD indices and local thermal comfort criteria. International Standardisation Organisation, Geneva.] and by ASHRAE [ASHRAE Handbook, 2005. Fundamentals. Chapter 8. American Society of Heating Refrigeration and Air-conditioning Engineers, Inc., 1791 Tullie Circle N.E., Atlanta, GA.]. To date, thermal insulation values of mainly Western clothing have been published with only minimal data being available for non-Western clothing. Thus, the objective of the present study is to measure and present the thermal insulation (clo) values of a number of Arabian Gulf garments as worn by males and females. The clothing ensembles and garments of Arabian Gulf males and females presented in this study are representative of those typically worn in the region during both summer and winter seasons. Measurements of total thermal insulation values (clo) were obtained using a male and a female shape thermal manikin in accordance with the definition of insulation as given in ISO 9920. In addition, the clothing area factors (f cl) determined in two different ways were compared. The first method used a photographic technique and the second a regression equation as proposed in ISO 9920, based on the insulation values of Arabian Gulf male and female garments and ensembles as they were determined in this study. In addition, fibre content, descriptions and weights of Arabian Gulf clothing have been recorded and tabulated in this study. The findings of this study are presented as additions to the existing knowledge base of clothing insulation, and provide for the first time data for Arabian Gulf clothing. The analysis showed that for these non-Western clothing designs, the

  4. European cloth and "tropical" skin: clothing material and British ideas of health and hygiene in tropical climates.

    Johnson, Ryan

    2009-01-01

    As Britain's imperial and colonial ambitions intensified toward the end of the nineteenth century, the preservation of white European health in tropical climates became an increasingly important concern. Since at least the seventeenth century, the "tropics" had been seen as spaces holding vast potential wealth but also death and disease. To combat these deadly but desirable landscapes, the British built a considerable commodity culture around the preservation of white European health, and for many, tropical clothing was one of the most important and essential items in their "kits." This article investigates the composition and use of such clothing in relation to British ideas of health and hygiene in tropical climates. First, it considers debates that ensued over the best material--wool, cotton, linen, silk, or a combination of these materials--and the role of "black" skin and local practice in the development of tropical clothing. Second, it demonstrates the importance of location in any discussion of tropical medicine and hygiene, and the tension and ambiguity that still surrounded British ideas of health and hygiene in the tropical colonies. Third, it argues that tropical clothing was important in the maintenance of climatic etiologies despite advances in parasitology and sanitary science. Finally, it considers the relationship of tropical clothing to the formation of a unique colonial identity. To British men and women embarking for any number of tropical destinations, proper clothing was not a banal and mundane component of their outfitting. For many, the clothing signified a departure from the safe and "civil" climes of Britain for adventure in the expanding tropical empire.

    Experiments have been performed to demonstrate that near infrared (NIR) transmission through a wide range of clothing materials is possible. Studies have shown that the characteristics of NIR transmission are affected by both the type of fibre used, and the weave pattern. A series of experiments has indicated that NIR transmission is also dependent on other variables such as fabric porosity and dye colour. It is shown that, in many cases, transmission coefficients are sufficiently high that imaging and spectroscopy of objects hidden behind clothing samples should be possible. However, while transmission through clothing at NIR wavelengths in the 750-1,700 nm range is often more effective than in the visible or IR regions, the fabrics themselves will modify the transmitted signal in terms of spatial effects, intensity and spectral content. The paper also describes the possible use of near infrared signals to identify objects that are hidden behind clothing layers. This can be done using spectroscopy. It is important, however, to distinguish the various contributions that exist within the backscattered signal. A set of careful laboratory experiments have demonstrated that transmission through a set of different clothing fabrics does modify the spectral content of signals, but that the spectrum of a particular chemical can still be identified, provided certain steps are taken. These involve a set of careful calibration measurements, and the use of processing techniques for the retrieval of data. It will be shown that this is possible for both granular solids and selected liquids.

    In this paper, a study of clothes drying using a heat pump drier has been carried out. The objective is to examine the performance and drying characteristics of the heat pump clothes dryer. The result of performances and drying characteristics were compared with waste heat drying system of split-type residential air conditioner (RAC). A drying chamber with volume 1 m3 integrated with heat pump component had been designed and fabricated. The heat pump operated by vapor compression cycle with power input of 800W and refrigerant R22 as a working fluid. The clothes dried made of pure cotton with initial weight varied from 3.00 kg, 5.25 kg, and 6.38 kg, respectively. The results shown that the drying time and drying rate of heat pump drier are faster than waste heat drying system. The average total performance of heat pump clothes drier is 6.56. On the other hand, SMER which is obtained 1.492 kg/kWh. These values are lower than the SMER of waste heat drying system which shown the average value of 2.492 kg/kWh. In the case of drying clothes, waste heat drying of RAC shows a better performance in comparison with heat pump drying system.

    Contact burns from clothing irons are a common injury seen in children. These injuries occur when an unattended iron is within reach of toddlers in its upright position. In a previous study, the authors have shown that the surface of an iron takes 90 minutes to cool below the epidermal injury threshold of 49 degrees C. The authors have constructed an "iron shoe" to shield the iron surface from young hands during cooling. The device is intended to set the cooling iron in its down position providing additional protection. The device will insulate the iron surface to avoid the fire hazard when positioned in this manner. A silicone polymer was used to create an "iron shoe." This polymer is stable at temperatures up to 370 degrees C. The device included sidewalls to shield the edges from contact. Thermal analysis of the device was conducted using an inexpensive and expensive iron. Thermocouples were placed on the iron surface and below the iron shoe. The irons were heated to its maximum temperature, placed in the shoe and then unplugged. Temperature cooling curves were obtained from the thermocouples. The experiment was repeated by measuring the temperature difference between the iron edge and the shoe sidewalls. The surface of both expensive and inexpensive irons reached a maximum of 205 degrees C. The temperature below the iron shoe reached a maximum of 49 degrees C (inexpensive) and 60 degrees C (expensive). The iron edge temperature reached a maximum of 188 degrees C (inexpensive) and 154 degrees C (expensive). The shoe sidewall temperature achieved a maximum of 52 degrees C (inexpensive) and 49 degrees C (expensive). Both expensive and inexpensive irons reach temperatures over 200 degrees C. The silicone "iron shoe" effectively shielded the surface and edge of both irons and approached the epidermal injury threshold of 49 degrees C. The temperature beneath the expensive iron did exceed 49 degrees C, but because the intention of the device is to place the iron in

    CLOTHING, as the old Chinese saying goes, is regarded as the most basic human need. In 1988 in Beijing, the first institute of higher learning to focus on the design and manufacture of clothing was established. The Beijing Institute of Clothing Technology (BICT) offers a combined curriculum of art and fashion that has fostered the talent of many outstanding young designers. The college is located near the ruins of the city wall from the Yuan Dynasty (1271-1368) and has an enrollment of 2,500 undergraduate and graduate students. Before 1988 the building housed a college of chemical fibre engineering that had many lecturers and professors who where considered accomplished at both theory and application. The school was expanded with the addition of nine subjects and three new departments—Garment,

    The response of a MEMS device that is exposed to a harsh environment may range from an increased noise floor to a completely erroneous output to temporary or even permanent device failure. One such harsh environment is high power acoustic energy possessing high frequency components. This type of environment sometimes occurs in small aerospace vehicles. In this type of operating environment, high frequency acoustic energy can be transferred to a MEMS gyroscope die through the device packaging. If the acoustic noise possesses a sufficiently strong component at the resonant frequency of the gyroscope, it will overexcite the motion of the proof mass, resulting in the deleterious effect of corrupted angular rate measurement. Therefore if the device or system packaging can be improved to sufficiently isolate the gyroscope die from environmental acoustic energy, the sensor may find new applications in this type of harsh environment. This research effort explored the use of microfibrous metallic cloth for isolating the gyroscope die from environmental acoustic excitation. Microfibrous cloth is a composite of fused, intermingled metal fibers and has a variety of typical uses involving chemical processing applications and filtering. Specifically, this research consisted of experimental evaluations of multiple layers of packed microfibrous cloth composed of sintered nickel material. The packed cloth was used to provide acoustic isolation for a test MEMS gyroscope, the Analog Devices ADXRS300. The results of this investigation revealed that the intermingling of the various fibers of the metallic cloth provided a significant contact area between the fiber strands and voids, which enhanced the acoustic damping of the material. As a result, the nickel cloth was discovered to be an effective acoustic isolation material for this particular MEMS gyroscope.

    Carcass mass largely affects pattern and rate of carrion decomposition. Supposedly, it is similarly important for carrion entomofauna; however, most of its likely effects have not been tested experimentally. Here, simultaneous effects of carcass mass and clothing are analyzed. A factorial block experiment with four levels of carcass mass (small carcasses 5-15 kg, medium carcasses 15.1-30 kg, medium/large carcasses 35-50 kg, large carcasses 55-70 kg) and two levels of carcass clothing (clothed and unclothed) was made in a grassland habitat of Western Poland. Pig carcasses (N = 24) were grouped into spring, early summer, and late summer blocks. Insects were sampled manually and with pitfall traps. Results demonstrate that insect assemblages are more complex, abundant, and long-lasting on larger carcasses, whereas clothing is of minor importance in this respect. Only large or medium/large carcasses were colonized by all guilds of carrion insects, while small or medium carcasses revealed high underrepresentation of late-colonizing insects (e.g., Cleridae or Nitidulidae). This finding indicates that carcasses weighing about 23 kg-a standard in forensic decomposition studies-give an incomplete picture of carrion entomofauna. Residencies of all forensically relevant insects were distinctly prolonged on larger carcasses, indicating that cadaver mass is a factor of great importance in this respect. The pre-appearance interval of most taxa was found to be unrelated to mass or clothing of a carcass. Moreover, current results suggest that rate of larval development is higher on smaller carcasses. In conclusion, this study demonstrates that carcass mass is a factor of crucial importance for carrion entomofauna, whereas the importance of clothing is small.

    Currently, threats caused by pathogens are serious public health problems worldwide. Protective clothing is essential when one is treating infected patients or dealing with unknown pathogens. Therefore, it is necessary to evaluate the performance of protective clothing against pathogens. In Japan, some methods for evaluating the performance of protective clothing have been established in the Japanese Industrial Standards (JIS). However, a test method against virus aerosols has not been established. Because there is a risk of infection from a live virus during the test, it is necessary to devise a safe method for the virus-aerosol-based test. Here, we propose a new method of safely measuring virus aerosols for the performance evaluation of protective clothing materials. To ensure safety, an inactivated virus was used. As a model virus, the influenza virus was selected owing to the proper small diameter of the virus particles. To quantitatively measure the particle-amount of the inactivated influenza virus, we developed an antigen-capture enzyme-linked immunosorbent assay (ELISA) targeting the M1 protein. Furthermore, we evaluated two materials using our method. Significant differences in the protection performance against the virus aerosol were observed between different sample materials, thereby confirming the applicability of our new method for performance evaluation.

    During the commission of crimes blood can be transferred to the clothing of the offender or on other crime related objects. Bloodstain particles are sub-millimetre sized flakes that are lost from dried bloodstains. The nature of these red particles is easily confirmed using spectroscopic methods. In casework, bloodstain particles showing highly detailed morphological features were observed. These provided a rationale for a series of experiments described in this work. It was found that the "largest" particles are shed from blood deposited on polyester and polyamide woven fabrics. No particles are lost from the stains made on absorbent fabrics and from those made on knitted fabrics. The morphological features observed in bloodstain particles can provide important information on the substrates from which they were lost. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

  10. THE RELATIONSHIP BETWEEN WORDS, TEXTS, CLOTHES AND TEXTILES

    Directory of Open Access Journals (Sweden)

    STURZA Amalia

    2017-05-01

    Full Text Available In this paper we will speculate the possible relationships between “word,” “text,” “textile,” and “clothing”. Many of the terms we use to describe our interactions with words are derived from the common linguistic root and numerous other expressions associated with reading and writing are drawn from the rich vocabulary of cloth. Textiles are one of the most ubiquitous components of material culture and they are also integral to the material history of texts. The intersection between texts and textiles locates the relationship between language and dress, as together they structure the fashion scene over the century. We compare these texts and storytelling with the process of making clothes, they go from fibers that are spun and then create the fabric or the material out of which the clothes are made. Besides the similitude of the words “text” and “textile” that have four similar letters there is also the resemblance in the way they transmit a message. While texts are meant to transmit something to the reader, to enchant and to create emotions in so various ways, just in the same way clothes are also meant to transmit emotions and feelings to the wearer or to the people watching them.

    2016-09-01

    We report on the successful use of direct PCR amplification of single fibers from items of worn clothing. Items of clothing were worn throughout the course of a day, with the individual commencing regular activities. Single fibers were taken from the cuff of the clothing at regular intervals and amplified directly. The same areas were subjected to tape-lifting, and also amplified directly for comparison. The NGM™ kit that amplifies 15 STR loci plus amelogenin was used. A total of 35 single fiber samples were processed and analyzed from five items of clothing, with 81 % of samples returning a profile of 14 alleles or more. All tape-lift samples amplified directly produced DNA profiles of 15 alleles or more. The aim was to develop a simple, operational method that could be used routinely in forensic science casework and that has the potential to generate more complete profiles, which would not be detected using standard extraction methods on this type of sample. For ease of implementation, the process also adheres to standard methods with no increase in the cycle number.

    Thorén, M

    1996-12-01

    Today's clothing market is not adapted for people with unusual body dimensions and/or different kinds of functional impairments. They will be referred to as disabled users. The method of user-oriented product development combined with the soft systems methodology has been applied in order to understand and possibly solve their problem. Sixty five disabled users were interviewed. The results show that the disabled users must be divided into subgroups. Their requirements are very much dependent on their impairment not only regarding the fit and function of the clothing, but also regarding shopping and service in the stores. The symbolic values of clothing are just as important as the functional values. However, it is essential not to focus on the end product only, but to look at the problem as a system consisting of: manufacturing, marketing and end use. A new method of taking three dimensional measurements from range images of the human body has been developed. In combination with other developments in information technology it will be possible to synthesise a new system where the manufacturers and retailers of clothing can co-operate in order to give service to disabled users.

    Monopolistic clothing store is the best place for clothing industry to present the complete identity and distinctive style of brands. Actually the brand identity is reflected not only from clothes itself, but also from different aspects, e.g. an ornament, a brochure, a logo, and a clothes rack, or the outside appearance of the store, the window display and the inside environment. So monopolistic clothing store should focus on promoting the philosophy of brand and present the brand identity in its visual designs.

    2016-12-01

    Full Text Available The currently used methods of ergonomic assessment of protective clothing depend on the subjective feeling of research participants and don’t take into consideration all aspects of its use. Therefore, more amount of work is undertaken toward the development of new research tools for the ergonomic assessment of protective clothing. Research was carried out at the Central Institute for Labour Protection – National Research Institute in Lodz. A new methodology will take into consideration a variant of reference clothing, which is related to the results of ergonomics research of protective clothing. Preparation of the reference clothing initiated by picking the appropriate fabric is based on the results of parameters influencing the physiological comfort and sensorial comfort. In the current part, results of different fabric parameters are presented, which are related to physiological comfort, i.e., the thermal resistance, water vapor resistance, hygroscopicity, and air permeability. In the next part of research, we will focus on the parameters related to objective sensorial feelings, i.e., total hand value and its components. Seven fabrics, including six cotton/polyester fabrics, diverse in terms of constituent fiber content and structure parameters (weave, thread density per 1 dm, thread linear density, mass per square meter, thickness, and Tencel/polyester fabric were tested. The best in terms of thermal resistance, water vapor resistance, and air permeability was the cotton/polyester fabric (35% cotton/65% PES with the smallest mass per square meter. This fabric also exhibits the high hygroscopicity of 7.5%, which puts it into the fourth position.

  9. Sustainability and Philanthropic Awareness in Clothing Disposal Behavior Among Young Malaysian Consumers

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available Young consumers are the stylish shoppers who have a strong tendency to follow the latest fashion. With the rapid changes in the fashion trends, the overconsumption of clothing has had a significant environmental impact on society. Hence, there is a need to understand how young fashionable consumers are disposing their unwanted clothes. The survey was conducted among 205 young respondents, and the results show that clothing disposal behavior is affected by philanthropic awareness and mediated by the attitude toward clothing disposal. Interestingly, environmental economic factors only influence clothing disposal behavior through the attitude toward the disposal of clothing. The findings provide a valuable insight into the government and related authorities or organizations in developing strategies to encourage young consumers to increase their clothing-recycling rate, and, thus, eliminate the environmental issues in near future.

    Full Text Available Social Representations is one of the most important theories in contemporary social psychology. Since the social psychologist Serge Moscovici developed his theory of social representations to explain how a scientific theory such as the psychoanalysis turns into a common sense knowledge many studies have been done by different social psychologists. The analysis of the social representations of women as represented in myths and popular beliefs is an excellent opportunity to study how this theory can be applied to this representational field. At the same time it makes possible to understand the formation of attitudes towards women

    Apart from helmets, little is known about the effectiveness of motorcycle protective clothing in reducing injuries in crashes. The study aimed to quantify the association between usage of motorcycle clothing and injury in crashes. Cross-sectional analytic study. Crashed motorcyclists (n=212, 71% of identified eligible cases) were recruited through hospitals and motorcycle repair services. Data was obtained through structured face-to-face interviews. The main outcome was hospitalization and motorcycle crash-related injury. Poisson regression was used to estimate relative risk (RR) and 95% confidence intervals for injury adjusting for potential confounders. Motorcyclists were significantly less likely to be admitted to hospital if they crashed wearing motorcycle jackets (RR=0.79, 95% CI: 0.69-0.91), pants (RR=0.49, 95% CI: 0.25-0.94), or gloves (RR=0.41, 95% CI: 0.26-0.66). When garments included fitted body armour there was a significantly reduced risk of injury to the upper body (RR=0.77, 95% CI: 0.66-0.89), hands and wrists (RR=0.55, 95% CI: 0.38-0.81), legs (RR=0.60, 95% CI: 0.40-0.90), feet and ankles (RR=0.54, 95% CI: 0.35-0.83). Non-motorcycle boots were also associated with a reduced risk of injury compared to shoes or joggers (RR=0.46, 95% CI: 0.28-0.75). No association between use of body armour and risk of fracture injuries was detected. A substantial proportion of motorcycle designed gloves (25.7%), jackets (29.7%) and pants (28.1%) were assessed to have failed due to material damage in the crash. Motorcycle protective clothing is associated with reduced risk and severity of crash related injury and hospitalization, particularly when fitted with body armour. The proportion of clothing items that failed under crash conditions indicates a need for improved quality control. While mandating usage of protective clothing is not recommended, consideration could be given to providing incentives for usage of protective clothing, such as tax exemptions for safety

  12. HIGHLIGHTS OF THE REPRESENTATION COSTUME IN PICTORIAL ART- BAROQUE STYLE -

    Directory of Open Access Journals (Sweden)

    URDEA Olimpia

    2014-05-01

    Full Text Available Throughout the social history of human civilization and art history, the human body was and still is a challenging field to explore in various representations, a material for various manners of cultural interventions. The way of artistically representing the body, the clothed body, has followed the path of various artistic movements that marked art history. In the act of interpersonal perception, the costume establishes itself as a particular field of non-verbal communication, one based on image. The present paper refers to the costume, as a particular vector of non-verbal communication in social space, as it was depicted and perceived in the painting of the 17th century and early 18th century, a time marked by the Baroque style. From this point of view, garment received the value of an intermediary in the communication between bodily space and the social one. In Baroque formal portrait, the garment completes by scale and the rendering technique of the texture and chromatic emphasizes the position of the pictorially represented person. Thus, the garment interferes with the gesture and mimics as forms of interpersonal knowledge. The transmitter – the clothed character represented through the eyes of the painter – is exposed to the perceptions of the others, providing a comprehensive matrix of information integrated in the social context. Pictorial representations are included in the matrix of the means by which the body is exposed by the costume in order to communicate with the social environment

    The deposition to human body surfaces of potentially hazardous aerosol has been investigated through tracer experiments. Particles of different sizes labelled with neutron activatable rare earth tracers were released in test rooms and deposited on volunteers. Various sampling techniques to examine the clearance and retention of the aerosol to skin, hair and clothing were investigated, and a protocol for the most efficient procedure was established and validated. Experiments indicate that the deposition velocity to skin increases linearly with the particle size. A wind tunnel experiment simulating outdoor conditions showed outdoor deposition velocities to be almost an order of magnitude higher than those recorded indoors. Both in vivo and in vitro experiments were conducted, and the influence of various factors, such as surface type, air flow, heating and electrostatics were examined. The dynamics of particle removal from human skin were studied by fluorescence scanning. Using the experimentally determined parameters, a model was established for calculation of radiation doses received from deposition of airborne radioactive aerosol on human body surfaces. It was found that the gamma doses that could be expected from deposition on skin were of the same order of magnitude as the gamma doses received over several years from contamination on outdoor surfaces. Assuming very high dry contamination levels, as were recorded in some areas of Russia after the Chernobyl accident, it was found that beta doses from skin deposition may amount to several Sievert and thus be responsible for a significant cancer risk.

    This study describes the application of confocal Raman microscopy to the detection and identification of drugs-of-abuse in situ on undyed natural synthetic fibres, and coloured textile specimens. Raman spectra were obtained from drug particles trapped between the fibres of the specimens. Pure samples of cocaine hydrochloride and N-methyl-3,4-methylenedioxy-amphetamine HCl (MDMA-HCl) were used in this study. Raman spectra were collected from drug particles of an average size in the range 5-15 {mu}m. Despite the presence of spectral bands arising from the natural and synthetic polymer and dyed textiles, the drugs could be identified by their characteristic Raman bands. If necessary, interfering bands could be successfully removed by spectral subtraction. Furthermore, Raman spectra were recorded from drug particles trapped between the fibres of highly fluorescent specimens. Interference from the fibres, including background fluorescence, was overcome by careful focusing of the confocal beam and the resulting spectra allow ready differentiation from interference from the fibres substrate bands. Spectra of several drugs-of-abuse on dyed and undyed clothing substrates were readily obtained within 3 min with little or no sample preparation and with no alteration of the evidential material.

    2014-01-01

    This study compared two different laminar airflow distribution strategies - horizontal and vertical - and investigated the effectiveness of both ventilation systems in terms of reducing the sedimentation and distribution of bacteria-carrying particles. Three different staff clothing systems, which resulted in source strengths of 1.5, 4 and 5 CFU/s per person, were considered. The exploration was conducted numerically using a computational fluid dynamics technique. Active and passive air sampling methods were simulated in addition to recovery tests, and the results were compared. Model validation was performed through comparisons with measurement data from the published literature. The recovery test yielded a value of 8.1 min for the horizontal ventilation scenario and 11.9 min for the vertical ventilation system. Fewer particles were captured by the slit sampler and in sedimentation areas with the horizontal ventilation system. The simulated results revealed that under identical conditions in the examined operating room, the horizontal laminar ventilation system performed better than the vertical option. The internal constellation of lamps, the surgical team and objects could have a serious effect on the movement of infectious particles and therefore on postoperative surgical site infections.

    Chemical functionalization of an activated carbon cloth with 3-aminophthalic acid and 4-aminobenzoic acid groups by the in situ formation of the corresponding diazonium salt in aqueous acidic solution is reported. The nature and amount of selected functions on an activated carbon surface, in particular the grafted density, were determined by potentiometric titration, elemental analysis and X-ray photoelectron spectroscopy (XPS). The nanotextural properties of the modified carbon were explored by gas adsorption. Functionalized activated carbon cloth was obtained at a discrete grafting level while preserving interesting textural properties and a large porous volume. Finally, the grafting homogeneity of the carbon surface and the nature of the chemical bonding were investigated using Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS) technique.

  17. Global Quota System and China's Textile and Clothing Industry

    2006-01-01

    By the middle of 2005, many Chinese textile and clothing enterprises were unable to continue business. Because of the safeguard actions invoked by WTO member countries, especially the USA, the EU and some developing countries, such as Turkey and Mexico, a stable and predictable overseas market no longer exists for export-oriented Chinese firms. It had actually been predicted that China would be the big winner after the elimination of the global quota system on 1 January 2005. What has happened to China's textile and clothing industries? What are the prospects for them over the next few years? Using a partial equilibrium analysis framework, this paper finds that China was the big loser under the quota system before 2005, and that China will be the big loser once again after the ending of that system.

    2001-11-07

    The goal of this project was to develop chemical protective clothing for use by DOE decontamination and decommissioning workers that is sufficiently water vapor permeable to keep the workers cool, thereby enhancing their productivity. This report describes the results of Phase II of a two-phase project to complete development of the novel permselective material and to test protective clothing made from the fabric. In Phase I a novel material incorporating a nonporous hydrophilic polyvinylacohol (PVA) layer, which is water vapor permeable but relatively impermeable to organic vapors, was developed. The results of the Phase I tests showed that the chemical resistance of the MTR material is comparable to that of Saranex/Tyvek materials, and that the comfort properties are closer to those of Tyvek (as measured in terms of CLO and permeability). Chemical resistance was measured using permeation tests against liquid dichloromethane. Comfort properties were ascertained by measuring the water vapor transmission of the material and by sweating manikin tests on whole protective suits. In addition, a cost/benefit analysis demonstrated that use of MTR's material technology could result in significant improvements in work productivity and cost savings if protective clothing items made from the new material were used more than once. In Phase II, MTR undertook a program to optimize the performance and production engineering for the new material technology. A partnership was formed with Kimberly-Clark Corporation to assist with a detailed evaluation of the MTR technology, and MTR used the services of Mr. Jeff Stull, President of the consulting firm International Personnel Protection, Inc., who conducted a detailed economic and application analysis for the developed fabric. The protective fabric manufacturing steps were simplified significantly, resulting in a 30% reduction in manufacturing costs and eliminating the necessity for capital investment in production equipment

    2017-01-01

    We introduce embedded data representations, the use of visual and physical representations of data that are deeply integrated with the physical spaces, objects, and entities to which the data refers. Technologies like lightweight wireless displays, mixed reality hardware, and autonomous vehicles are making it increasingly easier to display data in-context. While researchers and artists have already begun to create embedded data representations, the benefits, trade-offs, and even the language necessary to describe and compare these approaches remain unexplored. In this paper, we formalize the notion of physical data referents - the real-world entities and spaces to which data corresponds - and examine the relationship between referents and the visual and physical representations of their data. We differentiate situated representations, which display data in proximity to data referents, and embedded representations, which display data so that it spatially coincides with data referents. Drawing on examples from visualization, ubiquitous computing, and art, we explore the role of spatial indirection, scale, and interaction for embedded representations. We also examine the tradeoffs between non-situated, situated, and embedded data displays, including both visualizations and physicalizations. Based on our observations, we identify a variety of design challenges for embedded data representation, and suggest opportunities for future research and applications.

  9. Transient Structures. Layers of Social Meaning in Conceptual Clothing

    2016-06-01

    Full Text Available Within the conceptual framework of WLC 2016 we have chosen to explore a transdisciplinary approach of postmodern clothing. Fashion has always been a domain in which sociological, philosophical, political, cultural approaches have spoken about its contents and contexts. Recent sociological studies of fashion have revealed the deep meanings of conceptual clothing and the interwoven network of thoughts that is the starting point for such intellectual approaches. Fashion scholars such as Bradley Quinn, Caroline Evans, Valerie Steele or Malcolm Barnard have underlined the role of conceptual clothing in casting a light upon various social issues and symptoms. Through this paper we want to argument how layers of social meaning transform certain fashion projects in reflexions of the Zeitgeist. In the current socio-political context such investigations do not necessarily offer pertinent answers, but certainly raise more questions and awareness. By focusing on the works of Lucy and Jorge Orta, and Hussein Chalayan, our aim is to explore the different ways in which social changes, urban reconfigurations, and geographical dislocation question our notions of space, form, mobility, and identity. Our research will be a transdisciplinary one, analysing a consistent part of their work from different perspectives in order to reveal their influence on the way in which the design of clothing has taken the responsibility of becoming a shelter, a refuge, a mean of protection against the transient nature of contemporary societies. We will be analyzing Chalayan’s three projects, Afterwords (2000, Temporal Meditations (2003, and Absent Presence (2005, and Orta’s Refugee Wear (1992, Modular Architecture (1996, and Nexus Architecture (1993–2002. In investigating their works we shall focus on the character of artistic process, employed by both Chalayan and Orta, by using the objects (garments and the mechanisms of fashion (runway collection for Chalayan, and the

    Terrorism has been on the rise in the past decade and continues to disrupt everyday life in many parts of the world. Protection against such threats is therefore critical for preserving peace and security around the world. In particular, the safety of defense personnel engaged in confronting and responding to such threats must be ensured. Since textiles and clothing are pervasive and are always "on" the soldier, they can serve as an excellent infrastructure or platform for such individual protection systems.

ISBN: 1467557900. Đức documents in incredible detail the history of the sartorial decisions made at various Vietnamese courts, from Quyền’s time until the end of the Nguyễn dynasty. Based on an extensive examination of Vietnamese, Chinese, European, and even Korean sources—most of which only briefly mention clothing in various periods—Đức has succeeded in producing a comprehensive overview of the clothing of Vietnamese rulers and their officials; when possible, he also comments on the dress of other segments of society, such as the military and commoners. One Thousand Years of Caps and Robes devotes a chapter to each Vietnamese dynasty: the Lý, the Trần, the Lê, the Tây Sơn, and the Nguyễn. Đức begins each chapter with an overview of the history of that dynasty’s styles of court dress and then goes into a detailed description of exactly which types of cap and robe the ruler and his officials wore, and in what ways these caps and robes extended previous practices or were innovations. He follows his examination of court dress with a discussion of military and commoner attire. The chapter introductions provide a concise history of changes in court clothing across time, while the detailed discussions of the caps and robes from each period offer a deeper level of understanding...

  12. Architecture of Gothic Period and Its Effect to Clothing Design

    Full Text Available Root of the word Gothic comes from a German tribe which lives in region of the Gotland of Scandinavia. Gothic period is a movement which ends the Midde Age and opens Renaissance. Alth ough seen in all branches of the art, Gothic is widely a style of architecture. Having been originated from the Roman architecture, Gothic Architecture come out in the second half of the 12th century and continued its existence until the half of the 16th c entury when classical architecture come out. In Europe, Gothic painting, sculpture and architecture were dominant and preserved its popularity until the Renaissance. Fashion means all the temporary new styles which come out in a certain period of time with the desires of dressing up, being different, wearing the most desirable. Although seen as two different design field, when we examine closely, we can see that fashion and architecture has many common point from the past to present. As man is the common po int of this two field, they naturally affect each other. Gothic architecture inspired clothing designs, which is enough to show how much they affected each other. In this study, our purpose is to reveal effects of the Gothic architecture on the clothing d esigns. The style used in the Gothic period architecture and models and styles in clothing designs was presented with the help of table of specification. According to this, both fields' sharing common aesthetic concern and same theoritic and ideologic bas e was accompanied by stylistic and structural similarities accordingly. Designers in this two different fields turned even to themselves for inspiration and technical strategy. Environmental and cultural factors affect both fashion designers and architects . When seen as a part of historical process, clothes and buildings with their important cultural and economic conditions are priceless anthropological buildings which show technological developments within the period.

  19. Group and representation theory

    CERN Document Server

    Vergados, J D

    2017-01-01

    This volume goes beyond the understanding of symmetries and exploits them in the study of the behavior of both classical and quantum physical systems. Thus it is important to study the symmetries described by continuous (Lie) groups of transformations. We then discuss how we get operators that form a Lie algebra. Of particular interest to physics is the representation of the elements of the algebra and the group in terms of matrices and, in particular, the irreducible representations. These representations can be identified with physical observables. This leads to the study of the classical Lie algebras, associated with unitary, unimodular, orthogonal and symplectic transformations. We also discuss some special algebras in some detail. The discussion proceeds along the lines of the Cartan-Weyl theory via the root vectors and root diagrams and, in particular, the Dynkin representation of the roots. Thus the representations are expressed in terms of weights, which are generated by the application of the elemen...

    We introduce embedded data representations, the use of visual and physical representations of data that are deeply integrated with the physical spaces, objects, and entities to which the data refers. Technologies like lightweight wireless displays, mixed reality hardware, and autonomous vehicles...... are making it increasingly easier to display data in-context. While researchers and artists have already begun to create embedded data representations, the benefits, trade-offs, and even the language necessary to describe and compare these approaches remain unexplored. In this paper, we formalize the notion...... of physical data referents – the real-world entities and spaces to which data corresponds – and examine the relationship between referents and the visual and physical representations of their data. We differentiate situated representations, which display data in proximity to data referents, and embedded...

  1. Influence of illumination on autonomic thermoregulation and choice of clothing

    Kim, Seung Hi; Jeong, Woon Seon

    2002-04-01

    This study was conducted to investigate how different levels of illumination below 1,000 lx would affect the autonomic and behavioral temperature regulation of humans. Seven healthy college-aged women (20+/-0 years) volunteered to participate in this study. They were exposed to a temperature of 26 °C in 320 lx for 30 min ('Equilibrium') followed by 700 lx or 70 lx for 30 min (stage 1). After stage 1, they were exposed to 20 °C for 30 min in the same illumination as in stage 1 (stage 2). In stage 2 the subjects were instructed to select and wear the clothing they needed for their thermal comfort. The data obtained were analyzed by paired t-test and repeated measures of analysis of variance. Forearm skin blood flow tended to remain steady in 700 lx but decreased markedly in 70 lx in stage 1. There were no significant differences between subjective thermal responses of the subjects experiencing 700 lx or 70 lx in both stages although the subjects felt cooler in stage 2 than in stage 1. The subjects were likely to prefer wearing heavier clothing in 70 lx than in 700 lx. It was concluded that vasoconstriction in the upper limbs occurred more strongly in dim light, which might result in different clothing preferences in a cool environment from those associated with brighter light intensity.

  2. Fear no colors? Observer clothing color influences lizard escape behavior.

    2017-01-01

    Animals often view humans as predators, leading to alterations in their behavior. Even nuanced aspects of human activity like clothing color affect animal behavior, but we lack an understanding of when and where such effects will occur. The species confidence hypothesis posits that birds are attracted to colors found on their bodies and repelled by non-body colors. Here, we extend this hypothesis taxonomically and conceptually to test whether this pattern is applicable in a non-avian reptile and to suggest that species should respond less fearfully to their sexually-selected signaling color. Responses to clothing color could also be impacted by habituation to humans, so we examine whether behavior varied between areas with low and high human activity. We quantified the effects of four T-shirt colors on flight initiation distances (FID) and on the ease of capture in western fence lizards (Sceloporus occidentalis), and we accounted for detectability against the background environment. We found no differences in lizard behavior between sites. However, lizards tolerated the closest approaches and were most likely to be captured when approached with the T-shirt that resembled their sexually-selected signaling color. Because changes in individual behavior affect fitness, choice of clothing color by people, including tourists, hikers, and researchers, could impact wildlife populations and research outcomes.

  3. Analytical Provision of Profitable Activity of Clothing Industry Enterprises

    Full Text Available The goal of the article is improvement of the methodology of study of financial results through introduction into the domestic practice of application of modern instruments of methods of non-linear dynamics – catastrophe theory for analytical provision of management of profitability of clothing industry enterprises on its basis. In the result of the conducted study the article proves that the catastrophe theory is a conceptual and methodological basis for studying and forecasting financial results of activity of clothing industry enterprises as unstable to system changes and is a component of such a modern scientific direction as synergetics. The essence of the latter is that under conditions when in the course of conduct of main activity there is accumulation of a critical reserve of influence of various factors upon change of financial results, which, in their turn, undergo impact of various factors, including random ones, and at a certain point of time the activity becomes unprofitable, changing its qualitative characteristics in leaps and bounds, that is, it passes to a new trajectory of changes. The prospect of further studies in this direction is the study of behaviour of financial results of clothing production, which are negative for its activity due to uneven negative changes and which manifest themselves in unprofitable management due to unexpected reaction on correlation between the object of study and insignificant fluctuations of influence factors, in particular, in disproportions between the rates of growth of expenditure and income components of activity.

    Textiles are commonly treated with formaldehyde-based residues that may potentially induce allergic contact dermatitis in sensitive individuals. This study examined the initial formaldehyde content in clothing and resulting changes due to care activities. Twenty clothing articles were examined and 17 of them did not have detectable levels of formaldehyde. One shirt contained a formaldehyde concentration of 3172 ppm, and two pairs of pants had formaldehyde concentrations of 1391 ppm and 86 ppm. The two highest results represent formaldehyde levels that are up to 40-fold greater than international textile regulations. The two items with the greatest formaldehyde content were washed and dried in a manner similar to that used by consumers, including hand and machine washing in hot or cold water followed by air or machine drying. The washing and drying procedures reduced formaldehyde levels to between 26 and 72% of untreated controls. Differences in the temperature or type of washing and drying did not result in a clear trend in the subsequent formaldehyde content. In addition, samples were hot ironed, which did not affect the formaldehyde content as significantly. Understanding the formaldehyde content in clothing and its potential reduction through care activities may be useful for manufacturers and formaldehyde-sensitive individuals.

    The development of smart protective clothing will facilitate the quick detection of injuries from contact sports, traffic collisions and other accidents. To obtain real-time information like spatial and temporal pressure distributions on the clothing, flexible pressure sensor arrays are required. Based on a resistive fabric strain sensor we demonstrate all flexible, resistive pressure sensors with a large workable pressure range (0-8 MPa), a high sensitivity (1 MPa-1) and an excellent repeatability (lowest non-repeatability ±2.4% from 0.8 to 8 MPa) that can be inexpensively fabricated using fabric strain sensors and biocompatible polydimethylsiloxane (PDMS). The pressure sensitivity is tunable by using elastomers with different elasticities or by the pre-strain control of fabric strain sensors. Finite element simulation further confirms the sensor design. The simple structure, large workable pressure range, high sensitivity, high flexibility, facile fabrication and low cost of these pressure sensors make them promising candidates for smart protective clothing against impact loading.

The spatial form of fur garments is solved, in the main, constructive. The type, direction and amount of articulation were determined by the design of the product and the properties of the fur: the height of the hairline, the size of fur semi-finished product. The proposed positioning of the shaping of articulation in fur clothes has to be performed in the environment of 3D CAD. It is established that in modern models of the silhouette of a fur product may be formed not only by design divisions but also by a combination of the product of different types of fur. We have performed studies on the use of funds of formation in models of industrial collections fur coat 2015-16 presented on the trading spots of Moscow. We have conducted a monitoring of consumer preferences on the types of fur among women and determined the causes of loss of fur, clothing of spatial forms under adverse conditions of wearing. We have also proposed innovative means of formserialize in a fur garment of solid and perforated fur

    This study investigates symbolic meanings found in the Sunda ethnic clothing, particularly the Menak Priangan clothing. This study aims to uncover and document those symbolic meanings found in the Menak Priangan clothing as an effort to develop Sunda cultural artefacts of West Java. This study on Menak Priangan clothing applies ethnography (visual) and aesthetic methods. The visual method is utilized in order to uncover local cultural (Sunda) values found in Menak Priangan clothing visualization, including: design, model, name, and representing colours, which then directed towards local Sundanese aesthetic concepts living within the Priangan community. Furthermore, aesthetic method is used to explore role of aesthetic values in empowering visual cultural values within certain community, particularly Sunda aesthetic values. The study results show that since the 19th century, Sunda ethnic clothing was limited to Priangan Sunda only, while traditional clothing wearing by Priangan people reflects their social strata, consisting of: a. Menak Gede (Menak pangluhurna: mayor), bearing raden title, b. Menak Leutik/Santana (mayor assistant), titles: asep, mas, agus, ujang, (Nyimas for woman), c. Somah/Cacah: ordinary people/lower class. Clothing is a cultural phenomenon within certain culture reflecting such society experiences. For Menak people, clothing and its accessories have important meanings. They wear such traditional clothing and accessories as a symbol of power they have within bureaucratic structure and as a symbol of social status they bear within traditional community structure.

    An efficient adsorption process is developed for the decontamination of trivalent chromium from tannery effluents. A low cost activated carbon (ATFAC) was prepared from coconut shell fibers (an agricultural waste), characterized and utilized for Cr(III) removal from water/wastewater. A commercially available activated carbon fabric cloth (ACF) was also studied for comparative evaluation. All the equilibrium and kinetic studies were conducted at different temperatures, particle size, pHs, and adsorbent doses in batch mode. The Langmuir and Freundlich isotherm models were applied. The Langmuir model best fit the equilibrium isotherm data. The maximum adsorption capacities of ATFAC and ACF at 25 deg. C are 12.2 and 39.56 mg/g, respectively. Cr(III) adsorption increased with an increase in temperature (10 deg. C: ATFAC-10.97 mg/g, ACF-36.05 mg/g; 40 deg. C: ATFAC-16.10 mg/g, ACF-40.29 mg/g). The kinetic studies were conducted to delineate the effect of temperature, initial adsorbate concentration, particle size of the adsorbent, and solid to liquid ratio. The adsorption of Cr(III) follows the pseudo-second-order rate kinetics. From kinetic studies various rate and thermodynamic parameters such as effective diffusion coefficient, activation energy and entropy of activation were evaluated. The sorption capacity of activated carbon (ATFAC) and activated carbon fabric cloth is comparable to many other adsorbents/carbons/biosorbents utilized for the removal of trivalent chromium from water/wastewater.

    Interaction of pulsed transversely excited atmospheric (TEA) CO2-1aser radiation at 10.6 μm with nanoporous activated carbon cloth was investigated. Activated carbon cloth of different adsorption characteristics was used. Activated carbon cloth modifications were initiated by laser pulse intensities from 0.5 to 28 MW/cm^2, depending on the cloth adsorption characteristics. CO2 laser radiation was effectively absorbed by the used activated carbon cloth and largely converted into thermal energy. The type of modification depended on laser power density, number of pulses, but mostly on material characteristics such as specific surface area. The higher the surface area of activated carbon cloth, the higher the damage threshold.

    Correa, Diego H; Trancanelli, Diego

    2015-01-01

    We study the cusped Wilson line operators and Bremsstrahlung functions associated to particles transforming in the rank-$k$ symmetric representation of the gauge group $U(N)$ for ${\\cal N} = 4$ super Yang-Mills. We find the holographic D3-brane description for Wilson loops with internal cusps in two different limits: small cusp angle and $k\\sqrt{\\lambda}\\gg N$. This allows for a non-trivial check of a conjectured relation between the Bremsstrahlung function and the expectation value of the 1/2 BPS circular loop in the case of a representation other than the fundamental. Moreover, we observe that in the limit of $k\\gg N$, the cusped Wilson line expectation value is simply given by the exponential of the 1-loop diagram. Using group theory arguments, this eikonal exponentiation is conjectured to take place for all Wilson loop operators in symmetric representations with large $k$, independently of the contour on which they are supported.

    Electrodeposition of bimetallic Pt-Ru catalysts on O-functionalized graphite cloths from H{sub 2}PtCl{sub 6} and RuCl{sub 3} solutions containing trisodium citrate (Cit) and disodium dihydrogen ethylenediaminetetraacetate (Na{sub 2}H{sub 2}EDTA) was investigated. SEM analysis of the electrode prepared without complexant showed a relatively compact and rough deposit displaying a 'tree cortex' structure, whereas uniform size and globular shape particles regularly distributed over the support surface were obtained using citrate and Na{sub 2}H{sub 2}EDTA as complexants. In addition, XRD diffraction and EDX analysis revealed that the catalysts prepared using the complexants showed smaller size particles and lower Ru content. Electrocatalytic activity measurements indicated that the most active electrode for methanol oxidation was obtained with Na{sub 2}H{sub 2}EDTA as additive.

  17. Income, Ideology, and Representation

    Directory of Open Access Journals (Sweden)

    Chris Tausanovitch

    2016-11-01

    Full Text Available Do legislators represent the rich better than they represent the poor? Recent work provides mixed support for this proposition. I test the hypothesis of differential representation using a data set on the political preferences of 318,537 individuals. Evidence of differential representation in the House of Representatives is weak. Support for differential representation is stronger in the Senate. In recent years, representation has occurred primarily through the selection of a legislator from the appropriate party. Although the preferences of higher-income constituents account for more of the variation in legislator voting behavior, higher-income constituents also account for much more of the variation in district preferences. In light of the low level of overall responsiveness, differential responsiveness appears small.

    Currently, most trending clothes are specifically made to fit the shape of the human body. So, we can say that we are wearing clothes based on the clothing’s shape. However, due to disabilities and advanced age, there are people who are unable to wear these types of general clothing. But recently, certain brands have been receiving public attention for making clothes that are designed to fit, even the elderly. For my research, I propose a system in which customers, ranging from the younger ge...

    Full Text Available The aim of this paper is to analyse Croatian adolescents’ clothing buying motives and their retail store selection criteria. The paper examined their preferences, attitudes and behaviours when buying clothes - whether adolescents with different primary clothing motives would have similar or different store selection criteria. Also, the paper determined how today’s adolescents spend money on clothes and whether they are more inclined to purchase branded clothes or not. Finally, the paper explained whether Croatian adolescents prefer purchasing in small or large specialized apparel stores, or whether they are more prone to online purchasing or even buying clothes in second-hand shops. Also, the society influences in forming adolescents’ attitudes and decisions towards store selection and purchasing preferences of clothes were examined. The research findings showed that shopping centres are the preferred retail format. In addition, adolescents do not have a fully developed attitude on fashion and clothing. Therefore, they strongly refer to opinions of family and friends when choosing clothes. Moreover, the Internet and TV are evaluated as influential channels of consumer communication within this particular group of consumers. Based on the findings, suggestions for service management and marketing strategies are provided for apparel retail companies that target adolescents.

    Function emerges in certain kinds of far-from-equilibrium systems. One important kind of function is that of interactive anticipation, an adaptedness to temporal complexity. Interactive anticipation is the locus of the emergence of normative representational content, and, thus, of representation in general: interactive anticipation is the naturalistic core of the evolution of cognition. Higher forms of such anticipation are involved in the subsequent macro-evolutionary sequence of learning, emotions, and reflexive consciousness.

    Compared to a scalar pressure sensor,a vector sensor can provide a higher signal-to-noise ratio (SNR)signal and more detailed information on the sound field.Study on vector sensors and their applications have become a hot topic.Research on the representation of a vector field is highly relevant for extending the scope of vector sensor technology.This paper discusses the range-frequency distribution of the vector field due to a broadband acoustic source moving in a shallow-water waveguide as the self noise of a surface ship,and the vector extension of the waveguide impulse response measured over a limited frequency range using an active source of known waveform.From theory analysis and numerical simulation,the range-frequency representation of a vector field exhibits an interference structure qualitatively similar to that of the corresponding pressure field but,being quantitatively different,provides additional information on the waveguide,especially through the vertical component.For the range-frequency representation,physical quantities that can better exhibit the interference characteristics of the waveguide are the products of pressure and particle velocity and of the pressure and pressure gradient.An image processing method to effectively detect and isolate the individual striations from an interference structure was reviewed briefly.The representation of the vector impulse response was discussed according to two different measurement systems,also known as particle velocity and pressure gradient.The vector impulse response representation can not only provide additional information from pressure only but even more than that of the range-frequency representation.

  6. THE CURRENT STATE OF CLOTHING TRADE IN THE BALKAN COUNTRIES

    2017-05-01

    Full Text Available The study presented here is aimed at analysing the current state of clothing trade in the Balkan states. The dynamics of change over a 15‐year period following economic reforms are revealed. The clothing industries play a significant role and continue to contribute to the economic prosperity of countries with an inexpensive labour force. For most Balkan States clothing’s export plays an important role in promoting economic growth and development – for example, exports of garments Albania was in 2015, 16.81% of its exports, Republic of Macedonia 11.75% of its exports, in Turkey10.51% etc. The main factors which influence the level of competitiveness of clothing products from the Balkans are the gross value added per employee and wages. When the producers of the Balkan countries will create products with higher added value in garment industry the competitiveness of these countries will decrease. Also rising wages in this industry, as a result of trade union pressure or government policy, will lead to decreasing competitiveness of these products on the EU market and implicitly to the decrease of exports of garments from these countries. The main challenges that must face the Balkan States are related to restructuring of economic system, changing trade markets and patterns, declining of domestic demand of most merchandise, reduction of competitive ability, narrow export base, and lower economies of scale. The main opportunities that most of these countries can exploit are related to their geographical position, membership of the EU market, infrastructure in garment sector, and highly skilled workforce.

    Imagine how much could be saved in just 5 years if the garments that are sent to space are reduced by half. My project consisted in analyzing the efficiency of steam cleaning with and without pretreatment of selected garments. Crewmembers wear clothes for a certain period of time, and then these garments are discarded. Having crewmembers wearing their clothes for longer time while giving them the opportunity of reusing the garments (which at the moment is not possible) will reduce costs considerably. More importantly, it will build the path for sustaining human presence in deep space. In addition, reusing cleaned clothes will help crewmembers be in a more hygienic environment because the amount of trash will be reduced. By limiting the amount of garments that are sent, volume and mass will be reduced. As a result, there will be more space to pack other necessary goods. The main duties within the project were to develop a pre wash procedure that will be used for all of the fabrics (4 different fabrics were included in the experiment), to establish a time for the process of cleaning the garments with steam, to know the amount of oil and salt solution necessary to soil the fabric and that will be completely absorbed by the fabric, to determine the amount of chemical agent to use for removing the stains, to create a matrix with the SAS software that will have all the possible combinations to carry out during the experiment when soiling the shirts, to measure the stains before and after the steam process, to measure the cleanliness of the fabric before and after with the use of the Gray Scale for Staining, and to find out whether or not the observations are valid and useful.

    Full Text Available Today we can clearly see the damage which is caused by fast fashion production and mass consumption. Therefore, a relevant issue is how to reduce consumption, waste, and threat to the environment and human health. Research into the slow fashion designers approach towards eco-friendly and slow fashion products shows that it is necessary to spread ideas of slow fashion widely and teach users about ecologically friendly clothing. Therefore, this paper analyses theoretical and practical slow fashion principles applied by slow fashion designers; according to this, the collection ‘Just Share’ was created. The aim of the collection is to spread ideas of slow fashion and adapt them in specific technical projects dealing with the problems of use and production waste minimisation and creating sustainable, easily recyclable, environmentally friendly garments. Products for reducing consumption are developed based on the idea of sharing clothing. Therefore, garments are one size and suitable for different types of figures of men and women.  Clothing design is inspired by folding, so models have various pleats, unfolds allowing minimal transformation of the garment, which gives the product its individuality and extends time of wearing. Models are designed with a minimal amount of accessories and minimum division lines, maintaining the uniformity of materials and uncomplicated sewing technology. In this way, out of wear garments can be easily remade. Original constructions of models are based on the ‘zero waste’ principle. This method reduces waste generation. So this research was prepared using the principles of slow fashion, which has a potential to reduce excessive consumption and stop growth of textile waste.DOI: http://dx.doi.org/10.5755/j01.erem.71.2.12392

    Full Text Available Abstract Background Three-quarters of 3-6 year-old children in the U.S. spend time in childcare; many spend most of their waking hours in these settings. Daily physical activity offers numerous health benefits, but activity levels vary widely across centers. This study was undertaken to explore reasons why physical activity levels may vary. The purpose of this paper is to summarize an unexpected finding that child-care providers cited was a key barrier to children's physical activity. Methods Nine focus groups with 49 child-care providers (55% black from 34 centers (including inner-city, suburban, Head Start and Montessori were conducted in Cincinnati, OH. Three independent raters analyzed verbatim transcripts for themes. Several techniques were used to increase credibility of findings, including interviews with 13 caregivers. Results Two major themes about clothing were: 1 children's clothing was a barrier to children's physical activity in child-care, and 2 clothing choices were a significant source of conflict between parents and child-care providers. Inappropriate clothing items included: no coat/hat/gloves in the wintertime, flip flops or sandals, dress/expensive clothes, jewelry, and clothes that were either too loose or too tight. Child-care providers explained that unless there were enough extra coats at the center, a single child without a coat could prevent the entire class from going outside. Caregivers suggested several reasons why parents may dress their child inappropriately, including forgetfulness, a rushed morning routine, limited income to buy clothes, a child's preference for a favorite item, and parents not understanding the importance of outdoor play. Several child-care providers favored specific policies prohibiting inappropriate clothing, as many reported limited success with verbal or written reminders to bring appropriate clothing. Conclusion Inappropriate clothing may be an important barrier to children's physical

    To combat the risk of nightwear burns a mandatory standard regulating the design, flammability and labelling requirements of children's nightwear was introduced in Australia in 1987. This population-based study examined the trends, characteristics and causes of clothing-related burns to inform a review of the current standard, and to facilitate the development of targeted prevention strategies. Clothing-related burns for 1998-2013 were identified from hospitalisation data for all hospitals in NSW and detailed information regarding circumstance of injury from a burn data registry. To investigate percentage annual change (PAC) in trends negative binomial regression analysis was performed. There were 541 hospitalisations for clothing-related burns, 18% were nightwear-related and 82% were for other clothing. All clothing burns decreased by an estimated 4% per year (95% CI -6.2 to -2.1). Nightwear-related burns decreased by a significantly higher rate (PAC -7.4%; 95% CI -12.5 to -2.1) than other clothing (PAC -2.5%; 95%CI -4.7 to -0.1). Exposure to open heat source (campfire/bonfire) was the most common cause, followed by cooking. Of factors known to be associated with clothing burns, accelerant use was reported in 27% of cases, cigarettes 17%, loose skirt or dress 8%, and angle grinders in 6% of cases. Hospitalisations for clothing burns are relatively uncommon in NSW and rates, particularly of nightwear burns, have decreased over the last 15 years. Strategies for continued reduction of these injuries include increasing the scope of the current clothing standard or developing new standards to include all children's clothing and adult nightwear, and increasing community awareness of the risk associated with open heat sources, accelerant use and loose clothing.

    Thermoregulatory responses at ambient temperatures of 20 and 10° C in six male subjects wearing two different kinds of clothing were compared between summer and winter. The two different kinds of clothing were one insulating the upper half of the body lightly and the lower half of the body heavily (clothing A, the weight in the upper and lower halves of the body being, respectively, 489 g and 1278 g) and the other insulating the upper half of the body heavily and the lower half of the body lightly (clothing B: 1212 g and 559 g). The major findings are summarized as follow. (i) Rectal temperature was kept significantly higher in clothing B than in clothing A both in summer and winter. (ii) The fall of rectal temperature was significantly greater in summer than in winter in both types of clothing. (iii) Mean skin temperatures and skin temperatures in the face, chest, thigh and leg were significantly lower at T a of 10° C in summer than in winter in clothing A, while skin temperatures in the face and thigh were also significantly lower at T a of 10° C in summer than in winter in clothing B. (iv) Metabolic heat production was higher in summer than in winter at 20 and 10° C in both types of clothing. (v) The subjects felt cooler and colder to T a of 10° C in summer than in winter in both types of clothing. These different responses occurring between summer and winter are discussed mainly in terms of total conductance and dry heat loss.

    This paper aims to add a reference in revealing spatial thinking. There several definitions of spatial thinking but it is not easy to defining it. We can start to discuss the concept, its basic a forming representation. Initially, the five sense catch the natural phenomenon and forward it to memory for processing. Abstraction plays a role in processing information into a concept. There are two types of representation, namely internal representation and external representation. The internal representation is also known as mental representation; this representation is in the human mind. The external representation may include images, auditory and kinesthetic which can be used to describe, explain and communicate the structure, operation, the function of the object as well as relationships. There are two main elements, representations properties and object relationships. These elements play a role in forming a representation.

    2007-09-10

    What the participants share, their common "sense" of the world, creates a foundation, a framing, an orientation that enables human actors to see and act in coordination with one another. For recurrent activities, the methods the participants use to understand each other as they act change, making the intersubjective space in which actors operate richer and easier to produce. This article works through some of the issues that emerge from a close examination of intersubjectivity as it is managed through representation and interaction. The data that are presented document, in detail, a sequence of related interactions, within and across episodes of cooperation, where continuity and change can be observed. The emergence of conversational structure and coordinating representations are significant milestones in the long-term development of a representational practice that support the runtime co-construction of intersubjective space. Conversational structures emerge interactively to mediate recurrent points of coordination in the domain activity, and only secondarily the conversation itself. Coordinating representations change the representational practice of the participants by making it easier to manage their "shared view" of the collective work, enabling the participants to make progress, expand the field of the common activity, while exhibiting more control of if and when explicit grounding occurs.

    Full Text Available The study presented here is aimed at analyzing the comparative advantages in the European clothing sector with the focus on Balkan states. The dynamics of change over a 15‐year period following economic reforms are revealed. For all Balkan countries export plays an important role in promoting economic growth and development and the clothing industries play a significant role and continue to contribute to the economic prosperity in this countries. The evolution of the RCA index for garment industry is decreasing for all countries in the Balkans. The evolution of the Lafay index is also decreasing in the most Balkan countries (except Greece, Montenegro and Slovenia but still the values for Lafay index is positive what indicating that in these countries the sale of garments contribute positively to balance the trade balance of countries analyzed. Negative value of the Lafay index may be due to the fact that the garment industry is one of the key industries in the economy of that country and also because the earnings from garment industry in these countries is high. When the producers of the Balkan countries will create products with higher added value in garment industry the competitiveness of these countries will decrease. Also rising wages in this industry, as a result of trade union pressure or government policy, will lead to decreasing competitiveness of these products on the EU market and implicitly to the decrease of exports of garments from these countries.

    1995-10-01

    The objective of the program is to develop improved protective clothing for use by workers engaged in decommissioning and decontamination of former Department of Energy sites, including those used for atomic weapons research and production. Such sites are contaminated with a variety of hazardous compounds, ranging from asbestos, mercury and other heavy metals, to toxic organic compounds, such as PCB and chlorinated solvents, and radioactive metals and salts. Because of the hazards of exposure to these materials, workers must wear protective garments. These garments, which are made from Saran{reg_sign}, butyl rubber or other impermeable materials, provide excellent protection against particulates, liquids, aerosols, organic vapors and gases, but are impermeable to water vapor. Consequently, humidity and temperature within the suit rise rapidly during use, causing increasing discomfort. Heat stress occurs if the suit is worn for more than brief periods without resting. The proposed technology concerns a new protective clothing fabric that combines a permselective membrane layer with a sorptive layer. If successfully developed, suits made from this fabric will offer equivalent, or better, protection than current materials, combined with a very high water vapor transmission rate (1,000 g/m{sup 2}{sm_bullet} day or more) that will dramatically improve {open_quotes}breathability,{close_quotes} comfort, and worker productivity.

  5. Practicing Sustainability: Illuminating ‘Use’ in Wearing Clothes

    2016-03-01

    Full Text Available Aspects of the ordinary in everyday dressing remain elusive to fashion studies, meaning the life of what Judy Attfield calls ‘design in the lower case’ escapes notice. In this article, the authors assemble a practice-oriented perspective to illuminate ‘wearing’ as an outcome of sets of commonplace and routine practices related to dressing, that wear a garment in and out over time, and enhance the visibility of clothing use. The central example is a research project that tests the theory of loosening the meaning of clean by trialling alternative laundering techniques to understand the transition to sustain-ability, or less resource-intensive competencies in the spectrum of clothing use. The promise of an interdisciplinary conceptual framework that draws from ‘theories of practice’ at the intersection of cultural studies, sociology and design is also tested as appropriate for the analysis of the quotidian realm of wearing and laundering; the analysis is particularly assisted with sustainable design research about the transition toward sustainable ways of living such as the development of ‘slow fashion’.

    Full Text Available In January 2007 Romania joined the EU. Since then its current import duties for clothing and textiles has dropped a full 10% to between 6% and 8%. Consequently, import and re-export opportunities for Hong Kong, the Chinese mainland and other Asian suppliers are expected to increase, according to local Romanian importers. Chinese mainland firms are said to have invested US$254 million in the Romanian economy, but no details are available about the proportion directly invested in the clothing and textile sectors. Romania is now a lesser force in the garment and textile industry than it used to be, where it comes to feeding the EU market - even though the country is still the largest producer of such goods in Central and Eastern Europe, ahead of comparable economies such as Ukraine and Bulgaria. Romania also easily outcompetes more expensive labour in Hungary and Poland, neither of which are now considered contenders for price-sensitive trades, say Romanian analysts.

Absorbency is required for comfort properties in so me clothes such as sportswear and underwear clothing, for drying properties in napkins, towels and bathrobes, for health concerns in some medical textiles such as bandages, gauze and absorbent cotton, and for cleaning properties in washclothes and mops. In this study five different fabric samples (three woven 100% cotton fabrics A, B and P respectively at plain, twill, and peshtamal weaving patterns and two 100% cotton terry towels T1 and T2 were tested. The absorbency properties of the samples were evaluated according to the droplet test, sinking time test and wicking height tests (pottasium chromate test. Peshtamal samples showed better absorbency results than plain and twill weaves and lower but close results to towel samples according to the droplet test, sinking time test and wicking height tests. The absorbency properties of peshtamals showed results close to towel samples. The void content of peshtamals is higher than plain and twill samples but closer and lower than towel samples. The good absorbency results of peshtamals might be due to the void content of peshtamals which is higher than plain and twill samples but closer and lower than towel samples. Peshtamals which are good in absorbency and light in weight might be used widespreadly in daily life for their high absorbency, and on travel for weight saving purposes.

    Entomopathogenic fungi could be useful tools for reducing populations of the dengue mosquito Aedes aegypti. Here the efficiency of fungus (Metarhizium anisopliae) impregnated cloths (with and without imidacloprid [IMI]) was evaluated against adult A. aegypti in simulated human dwellings. Behaviour of mosquitoes in the presence of black cloths was also investigated. When mosquitoes were released into the test rooms, the lowest survival rates (38%) were seen when five black cloths impregnated with conidia of ESALQ 818 + 10 ppm IMI were fixed under tables and chairs. This result was significantly lower than the survival rate recorded when cloths were impregnated with ESALQ 818 alone (44%) or ESALQ 818 + 0.1 ppm IMI (43%). Blood fed A. aegypti had lower landing frequencies on black cloths than sucrose fed insects during the first 24 h following feeding, which may have been due to reduced flight activity. Few mosquitoes (4-5%) were observed to land on the cloths during the hours of darkness. The landing pattern of sucrose-fed mosquitoes on non-treated and fungus-treated cloths was similar. The synergism between M. anisopliae and IMI significantly reduced Aedes survival in simulated field conditions. The use of fungus impregnated cloths is a promising point source application method for the control of adult A. aegypti.

    The objective of this study was to describe knowledge of clothing flammability risk, public support for clothing flammability warning labels, and stronger regulation to reduce the risk. As part of a national survey of homeowners about residential sprinkler systems, the authors included questions about clothing flammability. The authors used an online web panel to sample homeowners and descriptive methods to analyze the resulting data. The sample included 2333 homeowners. Knowledge of clothing flammability and government oversight of clothing flammability risk was low. Homeowners were evenly split about the effectiveness of current standards; however, when presented with clothing-related burn injury and death data, a majority (53%) supported stricter standards. Most homeowners (64%) supported warning labels and indicated that such labels would either have no effect on their purchasing decisions (64%) or be an incentive (24%) to purchase an item. Owners of sprinkler-equipped homes were more likely to support these interventions than owners of homes without sprinkler systems. Public knowledge about clothing flammability risks is low. Most homeowners supported clothing labels to inform consumers of this risk and increased government intervention to reduce the risk.

    Multimodal interfaces, combining the use of speech, graphics, gestures, and facial expressions in input and output, promise to provide new possibilities to deal with information in more effective and efficient ways, supporting for instance: - the understanding of possibly imprecise, partial or ambiguous multimodal input; - the generation of coordinated, cohesive, and coherent multimodal presentations; - the management of multimodal interaction (e.g., task completion, adapting the interface, error prevention) by representing and exploiting models of the user, the domain, the task, the interactive context, and the media (e.g. text, audio, video). The present document is intended to support the discussion on multimodal content representation, its possible objectives and basic constraints, and how the definition of a generic representation framework for multimodal content representation may be approached.

  13. Post-representational cartography

    Directory of Open Access Journals (Sweden)

    Rob Kitchin

    2010-03-01

    Full Text Available Over the past decade there has been a move amongst critical cartographers to rethink maps from a post-representational perspective – that is, a vantage point that does not privilege representational modes of thinking (wherein maps are assumed to be mirrors of the world and automatically presumes the ontological security of a map as a map, but rather rethinks and destabilises such notions. This new theorisation extends beyond the earlier critiques of Brian Harley (1989 that argued maps were social constructions. For Harley a map still conveyed the truth of a landscape, albeit its message was bound within the ideological frame of its creator. He thus advocated a strategy of identifying the politics of representation within maps in order to circumnavigate them (to reveal the truth lurking underneath, with the ontology of cartographic practice remaining unquestioned.

    2017-02-01

    In this review I present several representation learning methods, and discuss the latest advancements with emphasis in applications to network science. Representation learning is a set of techniques that has the goal of efficiently mapping data structures into convenient latent spaces. Either for dimensionality reduction or for gaining semantic content, this type of feature embeddings has demonstrated to be useful, for example, for node classification or link prediction tasks, among many other relevant applications to networks. I provide a description of the state-of-the-art of network representation learning as well as a detailed account of the connections with other fields of study such as continuous word embeddings and deep learning architectures. Finally, I provide a broad view of several applications of these techniques to networks in various domains.

  15. Quantitative measurement of aerosol deposition on skin, hair and clothing for dosimetric assessment. Final report

    In the past, very little thought has been given to the processes and implications of deposition of potentially hazardous aerosol directly onto humans. This state of unpreparedness is unsatisfactory and suitable protocols have been developed and validated for tracer experiments to investigate the deposition and subsequent fate of contaminant aerosol on skin, hair and clothing. The main technique applied involves the release and subsequent deposition on volunteers in test rooms of particles of different sizes labelled with neutron activatable rare earth tracers. Experiments indicate that the deposition velocity to skin increases linearly with the particle size. A wind tunnel experiment simulating outdoor conditions showed a dependence on skin deposition velocity of wind speed, indicating that outdoor deposition velocities may be great. Both in vivo and in vitro experiments were conducted, and the influence of various factors, such as surface type, air flow, heating and electrostatics were examined. The dynamics of particle removal from human skin were studied by fluorescence scanning. This technique was also applied to estimate the fraction of aerosol dust transferred to skin by contact with a contaminated surface. The various parameters determined were applied to establish a model for calculation of radiation doses received from deposition of airborne radioactive aerosol on human body surfaces. It was found that the gamma doses from deposition on skin may be expected to be of the same order of magnitude as the gamma doses received over the first year from contamination on outdoor surfaces. According to the calculations, beta doses from skin deposition to individuals in areas of Russia, where dry deposition of Chernobyl fallout led to very high levels of contamination, may have amounted to several Sievert and may thus be responsible for a significant cancer risk.

    The cloth dehumidification is done by hot air circulation through it in dryers. The air circulation is done by a fan, run by an electrical motor, and the air temperature raise, which goes through the cloths aiming their moisture dragging, is gotten by the heat dissipation from electrical resistance. This work shows the results of an experimental modeling, examining the behavior of several kinds of cloth in a vertical suspense-type dryer, such as: polyester, cotton-spandex, flannel, blue-jeans and viscose rayon. It was analyzed the behavior of the moisture content in these cloths related to controlled-temperature-air flows, determining the needed heat to reach the required drying standards. The drying device fans were tested for the determination of their flow rate and energy consumption, establishing a flow rate versus consumption relationship. Comparative results among the various kinds of cloths are presented. (author)

    Full Text Available A computational clothing design tool is used to examine the effects of different clothing design features upon performance. Computational predictions of total heat and mass transfer coefficients of the clothing design tool showed good agreement with experimental measurements obtained using a sweating thermal manikin for four different clothing systems, as well as for the unclothed bare manikin. The specific clothing design features examined in this work are the size and placement of air-permeable fabric vents in a protective suit composed primarily of a fabric-laminated polymer film layer. The air-permeable vents were shown to provide additional ventilation and to significantly decrease both the total thermal insulation and the water vapor resistance of the protective suit.

    2011-12-01

    The purpose of this research was to develop a novel process that would achieve biocidal properties on Kevlar fabric via atmospheric pressure plasma jet (APPJ) induced-graft polymerization of monomers. In the course of the study, experiments were carried out to understand plasma-monomer-substrate interactions, particularly, how each of the main parameters in the plasma processing affects the formation of surface radicals and eventually the degree of graft polymerization of monomers. The study also served to explore the possibility of developing plasma-initiated and plasma-controlled graft polymerization for continuous operation. In this regards, three methods of processing were studied, which included two-step plasma graft-polymerization with immersion, two-step and one-step plasma graft-polymerization with pad-dry. In general, plasma treatment did not cause visible damage to the surface of Kevlar fibers, except for the appearance of tiny globules distributed almost uniformly indicating a minor effect of plasma treatment to the surface morphology of the polymer. From the examination of SEM images, however, it was found that a very localized surface etching seemed to have taken place, especially at high RF power (800 W) and long time of exposure (60 s), even in plasma downstream mode of operation. It was suggested that a small amount of charged particles might have escaped and reached the substrate surface. High density of surface radicals, which is the prerequisite for high graft density and high antimicrobial activity, was achieved by the combination of high RF power and short exposure time or low RF power and long time of exposure. This was a clear indication that the formation of surface radicals is a function of amount of the dissipated energy, which also explained the two-factor interaction between the two process parameters. XPS results showed that hydrolysis of the anilide bond of PPTA chains took place to some extent on the surface of Kevlar, leading to the

    The rapid development in the fields of sensor and telecommunication technologies has created completely new possibilities also for the textile and clothing field. New smart textile and clothing systems can be developed by integrating sensors in the textile constructions. Application fields for these added-value products are e.g. protective clothing for extreme environments, garments for the health care sector, technical textiles, sport and leisure wear. Some products have already been introduced on the markets, but generally it can be stated that the development is only in its starting phase, and the expectations for the future are big. Many different aspects have to be considered in the development of the wearable technology products for the health care sector: medical problems and their diagnosis, sensor choice, data processing and telecommunication solutions, clothing requirements. A functional product can be achieved only if all aspects work together, and therefore experts from all fields should participate in the RTD projects. In the EC-funded project DE3002 Easytex clothing and textiles for disabled and elderly people were investigated. Some recommendations concerning durability, appearance, comfort, service and safety of products for different special user groups were defined, based on user questionnaires and seminars, general textile and clothing requirements and on laboratory test series."Clothing Area Network--Clan" is a research project aiming to develop a technical concept and technology needed in enabling both wired and wireless data and power transfer between different intelligent modules (user interfaces, sensors, CPU's, batteries etc.) integrated into a smart clothing system. Fire-fighters clothing system is chosen as the development platform, being a very challenging application from which the developed technology can be transferred to other protective clothing systems.

  13. Women and political representation.

    1999-01-01

    A remarkable progress in women's participation in politics throughout the world was witnessed in the final decade of the 20th century. According to the Inter-Parliamentary Union report, there were only eight countries with no women in their legislatures in 1998. The number of women ministers at the cabinet level worldwide doubled in a decade, and the number of countries without any women ministers dropped from 93 to 48 during 1987-96. However, this progress is far from satisfactory. Political representation of women, minorities, and other social groups is still inadequate. This may be due to a complex combination of socioeconomic, cultural, and institutional factors. The view that women's political participation increases with social and economic development is supported by data from the Nordic countries, where there are higher proportions of women legislators than in less developed countries. While better levels of socioeconomic development, having a women-friendly political culture, and higher literacy are considered favorable factors for women's increased political representation, adopting one of the proportional representation systems (such as a party-list system, a single transferable vote system, or a mixed proportional system with multi-member constituencies) is the single factor most responsible for the higher representation of women.

    2012-01-01

    It often goes unnoticed that, even for a finite number of degrees of freedom, the canonical commutation relations have many inequivalent irreducible unitary representations; the free particle and a particle in a box provide examples that are both simple and well-known. The representations are unitarily inequivalent because the spectra of the position and momentum operators are different, and spectra are invariant under unitary transformations. The existence of these representations can have consequences that run from the merely unexpected to the barely conceivable. To start with, states of a single particle that belong to inequivalent representations will always be mutually orthogonal; they will never interfere with each other. This property, called superseparability elsewhere, is well-defined mathematically, but has not yet been observed. This article suggests two single-particle interference experiments that may reveal its existence. The existence of inequivalent irreducibile representations may be traced t...

    The highly energetic electron environment in the inner magnetosphere (GEO inward) has received a lot of research attention in resent years, as the dynamics of relativistic electron acceleration and transport are not yet fully understood. These electrons can cause deep dielectric charging in any space hardware in the MEO to GEO region. We use a new and novel approach to obtain a global representation of the inner magnetospheric energetic electron environment, which can reproduce the absolute environment (flux) for any spacecraft orbit in that region to within a factor of 2 for the energy range of 100 KeV to 5 MeV electrons, for any levels of magnetospheric activity. We combine the extensive set of inner magnetospheric energetic electron observations available at Los Alamos with the physics based Salammbo transport code, using the data assimilation technique of "nudging". This in effect input in-situ data into the code and allows the diffusion mechanisms in the code to interpolate the data into regions and times of no data availability. We present here details of the methods used, both in the data assimilation process and in the necessary inter-calibration of the input data used. We will present sample runs of the model/data code and compare the results to test spacecraft data not used in the data assimilation process.

    An alkaliphilic bacterium, Klebsiella sp. strain RJ-03, produced a biosurfactant, which showed low viscosity with pseudoplastic rheological behavior and exhibited emulsification activity with oils and hydrocarbons. The biosurfactant has excellent oil removing efficiency as compared to chemical surfactants. The isolated biosurfactant has compatibility with detergents and enhanced oil removing efficiency from soil and cotton cloths. It comprised of sugar, uronic acid, protein and sulfate. GC-MS analysis confirmed the presence of six monosaccharides (w/w), glucose (6.65%), galactose (23.98%), rhamnose (14.94%), mannose (17.54%), fucose (9.47%) and 6-O-Me-galactose (1.4%). It is a high molecular weight, thermostable biopolymer showing degradation above 300 °C. Positive ion reflector mode of MALDI TOF-TOF MS analysis revealed series of low and mid range mass peaks (m/z) corresponding to mono-, di-, tri- and oligo-saccharides content. The NMR, FT-IR, EDX-SEM, AFM and PSD analysis confirmed the presence of functional groups, bonds, elements and particle size respectively.

    MnO x , Mn/TiO2 and Fe-Mn/TiO2 catalysts were prepared by precipitation-impregnation method. The MnO x catalyst shows the highest activity for the reduction of NO with NH3 at the temperature range of 80 °C to 140 °C, and achieves more than 98% of NO conversion at 140 °C. The MnO x catalyst loaded on glass fiber cloth (GFC) was prepared by impregnation method, and the effects of preparation conditions were studied. It turns out that the catalyst particle size, loading capacity and catalyst varieties make a great difference to catalytic performance. In addition, the catalyst with aluminum sol as a binder has the higher catalytic activity but poor ability of anti-sulfur and anti-water poisoning, compared with the catalyst using silica sol binder. Further, MnO x , Mn/TiO2 and Fe-Mn/TiO2 powders were loaded onto GFC using XRD, HRTEM, TGA, SEM, BET, H2-TPR and NH3-TPD to systematically characterize the various physico-chemical properties and denitrition activity. The results indicate that the changes of active components, specific surface area, microstructure, reducibility and suface acidity of the three kinds of catalysts lead to different catalytic activities.

    Cooling function is definitely one of the most desirable attributes of clothing. In spite of the recent progress on phase changing material (PCM) research, the final products with sufficient amount of cooling capability have not yet to be developed in market. A new concept of cooling fabrics has been proposed by applying "Peltier effect" to textile materials. It occurs whenever electrical current flows through two dissimilar conductors; depending on the direction of current flow, the junction of the two conductors will either absorb or release heat. This effect has been tested on P-type and N-type conducting polymers. A P-type conductive polypyrrole coated fabric was synthesized by insitu polymerization on plain weave PET to make conductive fabrics. And an N-type electrically conductive material was synthesized by treatment of MWNT and polyethyleneimine (PEI). A noticeable amount of temperature difference has been found in the fabric.

    Knowledge representation is the core of artificial intelligence research. Knowledge representation methods include predicate logic, semantic network, computer programming language, database, mathematical model, graphics language, natural language, etc. To establish the intrinsic link between various knowledge representation methods, a unified knowledge representation model is necessary. According to ontology, system theory, and control theory, a standard model of knowledge representation that reflects the change of the objective world is proposed. The model is composed of input, processing, and output. This knowledge representation method is not a contradiction to the traditional knowledge representation method. It can express knowledge in terms of multivariate and multidimensional. It can also express process knowledge, and at the same time, it has a strong ability to solve problems. In addition, the standard model of knowledge representation provides a way to solve problems of non-precision and inconsistent knowledge.

    The purpose of this study was to develop anti-heat stress clothing for construction workers in hot and humid weather. Following DeJonge's functional clothing design process, the design situation was explored, including clothing fabric heat/moisture transporting properties and UV protection and the aspects of clothing ergonomic design (mobility, convenience, and safety). The problem structure was derived from the results of the surveys in three local construction sites, which agreed well with the task requirements and observations. Specifications were consequently described and 30 commercially available fabrics were identified and tested. Fabric testing data and design considerations were inputted in S-smart system to predict the thermal functional performance of the clothing. A new uniform prototype was developed and evaluated. The results of all measurements suggest that the new uniform which incorporated fabrics with superior heat/moisture transporting properties and loose-fitting design could reduce the workers' heat stress and improve their comfort and work performance. Practitioner Summary: The construction workers' uniform currently used in Hong Kong during summer was unsatisfactory. Following DeJonge's functional clothing design process, an anti-heat stress uniform was developed by testing 30 fabrics and predicting clothing thermal functional performance using S-smart system. The new uniform could reduce the workers' heat stress and improve their comfort and work performance.

    Single-use diapers and cloth diapers with vinyl pants were compared for their relative abilities to contain stool within the diaper. Artificial feces with carbon black as an additive allowed a quantitative measure of fecal containment by image analysis in 60 infants. This method showed complete containment of feces in the diaper in 50% of the single-use diapers whereas only 10% of the cloth diapers showed complete containment. In infants where the border of the vinyl pants was used as the boundary of containment with the cloth diapers, complete containment occurred only 33% of the time. Fluorescein dye ratings for containment/leakage in 69 infants showed that 83% of single-use diapers and 30% of the cloth diapers were rated as having no or minor leakage of feces. Cultures were taken of laundered vinyl pants that had previously been used over cloth diapers to determine microbial contamination. Thirty-nine percent of the pants contained Gram-negative, lactose-fermenting bacilli indicating fecal contamination. This study comparing single-use and cloth diapers for containment of artificial feces by use of image analysis and fluorescein dye ratings showed better containment by single-use diapers. The study also raises the question of possible spread of feces-borne pathogens by the vinyl pants used over cloth diapers, particularly in a day-care center.

    In the State of Rio Grande do Sul (RS), Southern Brazil, a good manufacturing practices regulation was published recommending two disinfection methods for cleaning cloths used in food services. The aim of the present study was to evaluate the efficacy of those methods. Cleaning cloths were sampled without prior notice at food services, on common working days. For the analyses, the cloths were divided in two sub-samples, being one of them microbiologically analyzed. The second sub-sample was further divided in two pieces and submitted to hand washing for two minutes. After that, one piece was boiled in water for 15 min and the other one was soaked in a 200 ppm sodium hypochlorite solution for 15 min. Both pieces of cloth were submitted to microbiological analyses. Cleaning cloths presented total aerobic mean counts of 6.9 ± 6.7 log/cm(2). All cleaning cloths presented coliform contamination, and 40% demonstrated mean counts of 6.2 ± 5.6 log/cm(2). Presumptive S. aureus mean counts of 5.5 ± 4.9 log/cm(2) were found. No statistic correlation was observed among the number of meals served daily in the food services and the microbiological contamination levels. After washing and disinfection, microbiological counts were significantly (p disinfect cleaning cloths used in food services.

    Quantitative characterization of the penetration of chemical residues through various types and configurations of clothing is an important underpinning of mitigation strategies to reduce dermal exposure to occupational cohorts. The objective of the evaluation presented herein is the development of pesticide clothing penetration (or conversely protection) factors for single layer clothing (i.e., long-sleeved shirt, long pants; gloves are not included) based on dermal exposure monitoring data (passive dosimetry) included in the Environmental Protection Agency's Pesticide Handlers Exposure Database (PHED). The analysis of penetration per replicate was conducted by comparison of the inside and outside (total deposition), expressed as mug/cm(2), for each replicate pair of dermal dosimeters. Clothing penetration was investigated as a function of job classification, dosimetry sampling method, body part, application method, and type of formulation. Grand mean single layer clothing penetration values for patch (n=2029) and whole-body (n=100) dosimeter samples from PHED were 12.12 (SE=0.33; SD=15.02) and 8.21 (SE=1.01; SD=10.14) percent, respectively. Linear regression was used to evaluate clothing penetration as a function of outer dosimeter loading. The regression analysis supports the hypothesis that single layer clothing penetration increases with decreasing outer dosimeter loading.

    Full Text Available An experiment was conducted to compare the collecting capacity of three types of beating cloth in sampling for soybeans caterpillars and stink bugs in different row spacing and cultivars. The experiment was conducted in a completely randomized design with six replications in a 2x3x3 factorial, using two cultivars (BMX Potencia RR and Fundacep 53 RR, three row spacing (0.4, 0.5 and 0.6 m and three types of beating cloth (beating cloth, wide beating cloth and vertical beat sheet. To determinate the collecting capacity of caterpillars, samples were taken at V9, V11 and R1 stages and for stink bugs, the samplings were performed at R5.3 and R5.5 stages. Results showed no interaction between the factors, indicating independence among them. Caterpillars had no preference between cultivars, however, stink bugs had a higher population density on Fundacep 53 RR. In the three evaluation dates, the density of larvae was higher when soybean was sown with reduced spacing. For stink bugs, higher infestation was observed on soybean sown with 0.4 m row spacing in the first assessment (R5.3, difference not observed in the evaluation at R5.5. The wide beating cloth and vertical beating cloth showed greater collecting capacity for caterpillars and bugs over beating cloth.

  15. SP: Measurements of Clothing Evaporative Resistance Using a Sweating Thermal Manikin: An overview.

    2017-06-01

    Evaporative resistance has been widely used to describe the evaporative heat transfer property of clothing. It is also a critical variable in heat stress models for predicting human physiological responses in various environmental conditions. At present, sweating thermal manikins provide a fast and cost-effective way to determine clothing evaporative resistance. Unfortunately, the measurement repeatability and reproducibility of evaporative resistance are rather low due to the complicated moisture transfer processes through clothing. This review article presents a systematical overview on major influential factors affecting the measurement precision of clothing evaporative resistance measurements. It also illustrates the state-of-the-art knowledge on the development of test protocol to measure clothing evaporative resistance by means of a sweating manikin. Some feasible and robust test procedures for measurement of clothing evaporative resistance using a sweating manikin are described. Recommendations on how to improve the measurement accuracy of clothing evaporative resistance are addressed and expected future trends on development of advanced sweating thermal manikins are finally presented.

    To investigate the influence of the general practitioner's style of clothing on the patient's level of confidence in that doctor; is vanity a functional attribute for the GP? Experimental comparative study. 4 photographic models representing 4 types of GP, namely the older male, younger male, older female and younger female GP, were each photographed dressed in 4 different styles of clothing (business wear, formal, semi-formal and casual). These photos were shown to evaluators with the question 'How much confidence do you have in this doctor?' The level of confidence was allocated a score on a numerical scale from 0 (no confidence) to 10 (complete confidence). There were 2 groups of evaluators: patients aged ≥ 65 years and professionals attending a symposium. The clothing style had a significant impact on the level of confidence in the older and younger male doctor and in the younger female doctor. The assessment by elderly patients (n = 116) differed significantly from the assessment by professionals (n = 59). The professionals had a far more pronounced opinion on style of clothing than the patients did. Business wear and formal clothing generally inspired more confidence than casual clothing. A GP's style of clothing affects the patient's initial level of confidence in that doctor. Vanity therefore seems to be a functional attribute for the GP.

  17. Competitive Potential in Clothing Exports for Hong Kong and the Interior of China

    Hong Kong and the Interior of China are leading clothing exporters in the world. Together they accounted for nearly 29 percent of the global clothing exports in 1999.The paper is basically divided into two parts. Firstly, it discusses that high world market share is an indicator of competitiveness for the product. From United Nations statistics, it was identified that Hong Kong and the Interior of China were competitive in certain discrete clothing items and a trend was apparent in the production shift of labour intensive clothing items from Hong Kong to the Mainland as witnessed from 1987-1993. With the revised statistical classification system in clothing items released by United Nations, second part of the paper further investigates the broad clothing categories of knitted and woven garments from 1987-1998. It was discovered that Hong Kong was traditionally more competitive in knitted garments while the Interior of China possessed advantages in the manufacture of woven items. Taking the labour cost advantage of the Interior of China and the marketing strengths of Hong Kong, their co-operation for clothing production is considered complementary to each other and able to foster synergistic effects.

  18. The migration of fragments of glass from the pockets to the surfaces of clothing.

    2011-05-20

    During the last decade or so there has been some discussion in the forensic community in the United Kingdom concerning whether it is necessary to search the pockets for glass particles in garments attributed to suspects arrested for glass breaking crimes. The removal of this practice would help expedite the searching and recovery process since examining only the surfaces of clothing would reduce the cost of recovering glass evidence. However, it is believed by many scientists that some glass fragments originally acquired in pockets can migrate to the surfaces of clothing prior to examination by the forensic scientist. As glass fragments have been encountered in the pockets of garments during examinations of casework items in the LGC Laboratories, the implications of this change in practice needs to be assessed. Hence, the aim of this study was to investigate this possibility that fragments of glass migrate from a pocket of a garment to its surfaces during police and laboratory handling after a person is suspected of breaking glass during an offence. If this occurs to a significant extent then it could affect the evaluation of the glass evidence when using a Bayesian approach. Sixty fragments of glass were seeded into a pocket of a fleece jacket and a pair of denim jeans. Three experiments were performed; one examined a searching, recovery and blanking procedure, another examined the pre-laboratory 'handling' process of an item in an evidence bag, and the third experiment looked at the removal of an object from a pocket laden with glass and subsequent removal and packaging of the garment. Up to two (3.3%) fragments were recovered from the surfaces of the fleece jacket and the denim jeans via the searching, recovery and blanking procedure. Similar numbers were also recovered from the insides of the evidence bags. Up to four (6.7%) fragments were recovered from the surface of the fleece jacket and up to five (8.3%) fragments were recovered from the surface of the

  20. The role of clothing in the pre-bourgeois ambience of Kersnik’s novels

    Directory of Open Access Journals (Sweden)

    Ana Perović

    2013-06-01

    Full Text Available The article focuses on the analysis of women’s and men’s clothing appearances in the prebourgeois ambience of Kersnik’s novels. Particular clothing items and clothing appearances indicate the presence of specific spiritual and social characteristics, typical for the cultural and historical environment in which the two literary works were created. The methodological approach of the analysis in terms of theory is based on general semiotic theory (Eco, Lotman, cultural semiotics (Barthes, literary theory and literary history, Lotman’s symbol theory, clothing culture, discourse analysis and Bourdieu’s theory of habitus. The article discusses separately the clothing appearances of male and female characters. The descriptions of clothing appearances reveal the socio-historical background of the literary works as well as many other abstract categories such as characters’ mental states, their ideologies, political beliefs, positive and negative character attributes as well as their moral virtues and vices. Clothes as part of the pre-bourgeois habitus try to establish a balance between the urban and the rural, between prestige and humility, between refi nement and coarseness. Irony is often a result of the contrast between the physical determinants and the associate variable, i.e. the clothing. The author uses a range of various clothing appearances to characterize and mock different classes of people; the trivial conversations about fashion denote the banality of social life; the differences between the “true” bourgeoisie and those who strive to reach and fi t into that social class are already strongly indicated in the descriptions of their external appearances.

    We uncover novel solutions of the 't Hooft anomaly matching conditions for scalarless gauge theories with matter transforming according to higher dimensional representations of the underlying gauge group. We argue that, if the duals exist, they are gauge theories with fermions transforming...... according to the defining representation of the dual gauge group. The resulting conformal windows match the one stemming from the all-orders beta function results when taking the anomalous dimension of the fermion mass to be unity which are also very close to the ones obtained using the Schwinger......-Dyson approximation.

    2014-01-01

    The accessibility of infovis authoring tools to a wide audience has been identified as a major research challenge. A key task in the authoring process is the development of visual mappings. While the infovis community has long been deeply interested in finding effective visual mappings......, comparatively little attention has been placed on how people construct visual mappings. In this paper, we present the results of a study designed to shed light on how people transform data into visual representations. We asked people to create, update and explain their own information visualizations using only...... tangible building blocks. We learned that all participants, most of whom had little experience in visualization authoring, were readily able to create and talk about their own visualizations. Based on our observations, we discuss participants’ actions during the development of their visual representations...

    Full Text Available Since the time of statement of the problem of states in psychology, the study of “sensuous” tissue – the mental state representation-takes a fundamental meaning. The problem is concluded in the following questions: “How is mental state represented in the consciousness of an individual?”, “What is the specificity of the mental state representation as distinguished from the subject-matter representation?”, “What are the mechanisms of the mental state representation occurrence and the peculiarities of its dynamics? The study of the mental state representation will allow to explain its specificity and difference from the figurative representation, the peculiarities of state explication as a representation in the consciousness and its relation with other elements of consciousness, will allow to show the regularities of the mental state representation development and its dynamics, factors, which influence the specificity of its occurrence, the regulatory role of the state representation in the vital function. From these perspectives, the article presents the results of the study of spatiotemporal characteristics of the mental state representation; reveals the peculiar features of the spatiotemporal organization of mental state representations: Relieves, specificity, magnitude, variability of indicators, changes of structural characteristics in time spans; considers the age-specific peculiar features of the spatiotemporal organization of mental state representations in terms of organization, stability, coherence and differentiated nature of spatiotemporal structures with the representatives of certain age groups.

    Transhfion is the faithful rcpresentation in one language of the thought, content, feeling and style written in another language. It involves two processes: comprehension and representation. Correct comprehension is the base for adequate representation. Criteria for good representation lies in two points: the version should be faithful to the original, and the version should be as intelligible as possible.

    2011-02-01

    In this paper, the prediction accuracy of the PHS (predicted heat strain) model on human physiological responses while wearing protective clothing ensembles was examined. Six human subjects (aged 29 ± 3 years) underwent three experimental trials in three different protective garments (clothing thermal insulation I(cl) ranges from 0.63 to 2.01 clo) in two hot environments (40 °C, relative humidities: 30% and 45%). The observed and predicted mean skin temperature, core body temperature and sweat rate were presented and statistically compared. A significant difference was found in the metabolic rate between FIRE (firefighting clothing) and HV (high visibility clothing) or MIL (military clothing) (p development of heart rate demonstrated the significant effects of the exposure time and clothing ensembles. In addition, the predicted evaporation rate during HV, MIL and FIRE was much lower than the experimental values. Hence, the current PHS model is not applicable for protective clothing with intrinsic thermal insulations above 1.0 clo. The results showed that the PHS model generated unreliable predictions on body core temperature when human subjects wore thick protective clothing such as firefighting clothing (I(cl) > 1.0 clo). The predicted mean skin temperatures in three clothing ensembles HV, MIL and FIRE were also outside the expected limits. Thus, there is a need for further extension for the clothing insulation validation range of the PHS model. It is recommended that the PHS model should be amended and validated by individual algorithms, physical or physiological parameters, and further subject studies.

  10. Momentum representation for equilibrium reduced density matrices

    CERN Document Server

    Golovko, V A

    2011-01-01

    The hierarchy of equations for reduced density matrices that describes a thermodynamically equilibrium quantum system obtained earlier by the author is investigated in the momentum representation. In the paper it is shown that the use of the momentum representation opens up new opportunities in studies of macroscopic quantum systems both nonsuperfluid and superfluid. It is found that the distribution over momenta in a quantum fluid is not a Bose or Fermi distribution even in the limit of practically noninteracting particles. The distribution looks like a Maxwellian one although, strictly speaking, it is not Maxwellian. The momentum distribution in a quantum crystal depends upon the interaction potential and the crystalline structure. The momentum distribution in a superfluid contains a delta function. The momentum distribution for the condensate in a superfluid crystal consists of delta peaks that are arranged periodically in momentum space. The periodical structure remains if the condensate crystal is not su...

    The complexity of quantitative biomedical models, and the rate at which they are published, is increasing to a point where managing the information has become all but impossible without automation. International efforts are underway to standardise representation languages for a number of mathematical entities that represent a wide variety of physiological systems. This paper presents the Field Representation Language (FRL), a portable representation of values that change over space and/or time. FRL is an extensible mark-up language (XML) derivative with support for large numeric data sets in Hierarchical Data Format version 5 (HDF5). Components of FRL can be reused through unified resource identifiers (URI) that point to external resources such as custom basis functions, boundary geometries and numerical data. To demonstrate the use of FRL as an interchange we present three models that study hyperthermia cancer treatment: a fractal model of liver tumour microvasculature; a probabilistic model simulating the deposition of magnetic microspheres throughout it; and a finite element model of hyperthermic treatment. The microsphere distribution field was used to compute the heat generation rate field around the tumour. We used FRL to convey results from the microsphere simulation to the treatment model. FRL facilitated the conversion of the coordinate systems and approximated the integral over regions of the microsphere deposition field.

  12. Translation between representation languages

    Vanbaalen, Jeffrey

    1994-01-01

    A capability for translating between representation languages is critical for effective knowledge base reuse. A translation technology for knowledge representation languages based on the use of an interlingua for communicating knowledge is described. The interlingua-based translation process consists of three major steps: translation from the source language into a subset of the interlingua, translation between subsets of the interlingua, and translation from a subset of the interlingua into the target language. The first translation step into the interlingua can typically be specified in the form of a grammar that describes how each top-level form in the source language translates into the interlingua. In cases where the source language does not have a declarative semantics, such a grammar is also a specification of a declarative semantics for the language. A methodology for building translators that is currently under development is described. A 'translator shell' based on this methodology is also under development. The shell has been used to build translators for multiple representation languages and those translators have successfully translated nontrivial knowledge bases.

  13. [Time perceptions and representations].

    2015-09-01

    Representations of time and time measurements depend on subjective constructs that vary according to changes in our concepts, beliefs, societal needs and technical advances. Similarly, the past, the future and the present are subjective representations that depend on each individual's psychic time and biological time. Therefore, there is no single, one-size-fits-all time for everyone, but rather a different, subjective time for each individual. We need to acknowledge the existence of different inter-individual times but also intra-individual times, to which different functions and different rhythms are attached, depending on the system of reference. However, the construction of these time perceptions and representations is influenced by objective factors (physiological, physical and cognitive) related to neuroscience which will be presented and discussed in this article. Thus, studying representation and perception of time lies at the crossroads between neuroscience, human sciences and philosophy. Furthermore, it is possible to identify several constants among the many and various representations of time and their corresponding measures, regardless of the system of time reference. These include the notion of movements repeated in a stable rhythmic pattern involving the recurrence of the same interval of time, which enables us to define units of time of equal and invariable duration. This rhythmicity is also found at a physiological level and contributes through circadian rhythms, in particular the melatonin rhythm, to the existence of a biological time. Alterations of temporality in mental disorders will be also discussed in this article illustrated by certain developmental disorders such as autism spectrum disorders. In particular, the hypothesis will be developed that children with autism would need to create discontinuity out of continuity through stereotyped behaviors and/or interests. This discontinuity repeated at regular intervals could have been

  14. Pioneers of representation theory

    Curtis, Charles W

    1999-01-01

    The year 1897 was marked by two important mathematical events: the publication of the first paper on representations of finite groups by Ferdinand Georg Frobenius (1849-1917) and the appearance of the first treatise in English on the theory of finite groups by William Burnside (1852-1927). Burnside soon developed his own approach to representations of finite groups. In the next few years, working independently, Frobenius and Burnside explored the new subject and its applications to finite group theory. They were soon joined in this enterprise by Issai Schur (1875-1941) and some years later, by Richard Brauer (1901-1977). These mathematicians' pioneering research is the subject of this book. It presents an account of the early history of representation theory through an analysis of the published work of the principals and others with whom the principals' work was interwoven. Also included are biographical sketches and enough mathematics to enable readers to follow the development of the subject. An introductor...

  15. Silk-Cloth Weaving Development of the Mon-Khmer Ethnic Group in Lower-Isan

    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

    These two methods allow the determination of the shape of the poles in magnets, for a given field distribution in the air-gap. First method: The principle of the method consists to create the desired law of field by means of current sheets in which one can adjust the density given in a polynomial form. For the right distribution of these currents, the equipotential corresponding to the magnetic potential of the excitation coils is calculated. The pole profile of the H or C magnet identified with this equipotential line will finally take the place of the distribution of the current sheets used in the calculation. Steel permeability is assumed to be infinite and Foucault current effects are neglected in the case of variable fields. Second method: It consists to find a conformal representation that maps the pole profile plane upon the upper half of another plane where the equipotentials are two half straight lines, and where the field problems are easier to solve. Steel permeability is also considered to be infinite and the coils far from the pole faces. This known method has been applied to be compared with the first one. (author) [French] Ces deux methodes consistent a determiner la forme des pieces polaires d'aimants pour une distribution de champ determinee a l'avance dans l'entrefer. Premiere methode: Le principe de la methode consiste a creer la loi de champ desiree par l'intermediaire de nappes de courant dont on peut ajuster la densite exprimee sous une forme polynominale. Pour une distribution convenable de ces courants, on calcule l'equipotentielle correspondant au potentiel magnetique des bobines d'excitation. Le profil polaire d'un aimant en H ou C identifie a l'equipotentielle se substitue finalement a la repartition des nappes de courant utilisee dans la methode de calcul. La permeabilite de l'acier est supposee infinie et les courants de Foucault sont negliges dans le cas des champs variables. Seconde methode

    2010-01-01

    A celebrated theorem of Pimsner states that a covariant representation $T$ of a $C^*$-correspondence $E$ extends to a $C^*$-representation of the Toeplitz algebra of $E$ if and only if $T$ is isometric. This paper is mainly concerned with finding conditions for a covariant representation of a \\emph{subproduct system} to extend to a $C^*$-representation of the Toeplitz algebra. This framework is much more general than the former. We are able to find sufficient conditions, and show that in important special cases, they are also necessary. Further results include the universality of the tensor algebra, dilations of completely contractive covariant representations, Wold decompositions and von Neumann inequalities.

  19. Braids as a representation space of SU(5)

    CERN Document Server

    Cartin, Daniel

    2015-01-01

    The Standard Model of particle physics provides very accurate predictions of phenomena occurring at the sub-atomic level, but the reason for the choice of symmetry group and the large number of particles considered elementary, is still unknown. Along the lines of previous preon models positing a substructure to explain these aspects, Bilson-Thompson showed how the first family of elementary particles is realized as the crossings of braids made of three strands, with charges resulting from twists of those strands with certain conditions; in this topological model, there are only two distinct neutrino states. Modeling the particles as braids implies these braids must be the representation space of a Lie algebra, giving the symmetries of the Standard Model. In this paper, this representation is made explicit, obtaining the raising operators associated with the Lie algebra of $SU(5)$, one of the earliest grand unified theories. Because the braids form a group, the action of these operators are braids themselves, ...

  20. Categorification and higher representation theory

    CERN Document Server

    Beliakova, Anna

    2017-01-01

    The emergent mathematical philosophy of categorification is reshaping our view of modern mathematics by uncovering a hidden layer of structure in mathematics, revealing richer and more robust structures capable of describing more complex phenomena. Categorified representation theory, or higher representation theory, aims to understand a new level of structure present in representation theory. Rather than studying actions of algebras on vector spaces where algebra elements act by linear endomorphisms of the vector space, higher representation theory describes the structure present when algebras act on categories, with algebra elements acting by functors. The new level of structure in higher representation theory arises by studying the natural transformations between functors. This enhanced perspective brings into play a powerful new set of tools that deepens our understanding of traditional representation theory. This volume exhibits some of the current trends in higher representation theory and the diverse te...

    Examination of cloths is a permanent sphere in the practice of forensic-medical expert and an indispensable expertise stage providing for decision-making on the key issues set before the expert. Although, the examination of cloth in forensic-medical expertise has been productive, research in this field slowed down during the recent decades; definition of new sets of evident informative signs has been also suspended. The methodological potentialities of examination of cloths items were demonstrated by examples of aviation incidents because such incidents reflect the principle variations of impacts, i.e. blow, explosion, fire, compression and chemical factors etc., which are subject to examination in the forensic-medical practice. Identification of mechanism causing damage and other signs on cloths helps a lot the forensic-medical expert in solving quite a number of issues related with circumstances of an incident and with a nature of an impact encountered by a person.

    It is desirable to maintain a low bacterial count in the operating room air to prevent surgical site infection. This can be achieved by ventilation or by all staff in the operating room wearing clothes made from low-permeable material (i.e. clean air suits). We investigated whether there was a difference in protective efficacy between a single-use clothing system made of polypropylene and a reusable clothing system made of a mixed material (cotton/polyester) by testing both in a dispersal chamber and during surgical procedures. Counts of colony-forming units (cfu)/m(3) air were significantly lower when using the single-use clothing system in both settings. Copyright © 2013 The Healthcare Infection Society.

    2015-07-01

    Twenty Sus scrofa carcasses were used to study the effect the presence of clothing had on decomposition rate and colonization locations of Diptera species; 10 unclothed control carcasses were compared to 10 clothed experimental carcasses over 58 days. Data collection occurred at regular accumulated degree day intervals; the level of decomposition as Total Body Score (TBSsurf ), pattern of decomposition, and Diptera present was documented. Results indicated a statistically significant difference in the rate of decomposition, (t427  = 2.59, p = 0.010), with unclothed carcasses decomposing faster than clothed carcasses. However, the overall decomposition rates from each carcass group are too similar to separate when applying a 95% CI, which means that, although statistically significant, from a practical forensic point of view they are not sufficiently dissimilar as to warrant the application of different formulae to estimate the postmortem interval. Further results demonstrated clothing provided blow flies with additional colonization locations.

    Diamond, G. G.; Gohel, R. B.

    2009-05-01

    A novel and low-cost technique of standoff detection is presented that permits the detection of explosives and other contraband substances that are hidden under clothing at standoff distances . The technique uses NIR beams of wavelengths found in ordinary domestic remote controls, combined with various signal recovery techniques commonly used in astronomy. This alternative technique, whilst sophisticated, utilises readily available optoelectronic components. It is inherently far more portable than currently available commercial alternatives and is easy to use. A pre-production prototype successfully detected and identified the common homemade explosives, ammonium nitrate and hydrogen peroxide, which were concealed behind clothing from a distance of 5 metres under daytime conditions. In principle, this distance could be extended as far as 50 metres without a significant increase in cost or complexity. Another advantage of this device is that apart from providing standoff chemical signatures and analyses of concealed substances, this it can simultaneously superimpose the chemical information on top of a normal TV image in a data fusion approach; that is, an image appears on the screen , the area/subject of interest can be zoomed in on and enlarged and a representation of a chemical spectrum appears on the screen underneath the image. A supplemental technique is also reported upon that, under the appropriate circumstances, enable actual imaging of concealed objects to be accomplished.

  18. FAST FASHON AND SECOND HAND CLOTHES BETWEEN ECOLOGICAL CONCERNS AND GLOBAL BUSINESS

    2014-05-01

    Full Text Available The paper presents the concept of the fast fashion and how these lead to an excessive consumption of clothes and as result a growth of the worn products market. The paper also aims to establish how fast fashion is influencing not only the economy also the environment. The fast fashion model can also damage developing economies with a low household income, which are not the necessary most important markets of these companies. Our study has identified the influences in increased purchase behavior and focused especially of the positive relationship between income and clothing expenses. We found out that it is a large gap between the European countries regarding clothing expenses in year and Romania is for far the lowest consumer. It is presented the second hand clothes import-export trade during 2007-2012 and we found out that there is an inverse relation between the balances sheet of import-export of textile products between the developed and developing countries. The authors conclude that the Romania is the largest European importer of second hand clothes but has no large scale recycling. Since collection is done on a voluntary basis it can be confusing for population to know how and where to discard used clothing therefore it is recommended a focus on collection systems of second hand clothes. The methodology used for this paper has mainly been a literature study where both scientific literature, such as scientific articles and reports, and popular science articles have been studied. We also use official information provided from National and International statistical Offices.

    Metals in textile products and clothing are used for many purposes, such as metal complex dyes, pigments, mordant, catalyst in synthetic fabrics manufacture, synergists of flame retardants, antimicrobials, or as water repellents and odour-preventive agents. When present in textile materials, heavy metals may mean a potential danger to human health. In the present study, the concentrations of a number of elements (Al, As, B, Ba, Be, Bi, Cd, Co, Cr, Cu, Fe, Hg, Mg, Mn, Mo, Ni, Pb, Sb, Sc, Se, Sm, Sn, Sr, Tl, V, and Zn) were determined in skin-contact clothes. Analysed clothes were made of different materials, colours, and brands. Interestingly, we found high levels of Cr in polyamide dark clothes (605 mg/kg), high Sb concentrations in polyester clothes (141 mg/kg), and great Cu levels in some green cotton fabrics (around 280 mg/kg). Dermal contact exposure and human health risks for adult males, adult females, and for <1-year-old children were assessed. Non-carcinogenic and carcinogenic risks were below safe (HQ<1) and acceptable (<10{sup −6}) limits, respectively, according to international standards. However, for Sb, non-carcinogenic risk was above 10% of the safety limit (HQ>0.1) for dermal contact with clothes. - Highlights: • We determined in skin-contact clothes the concentrations of a number of metals. • Dermal contact exposure and health risks for adults and for 1-year-old children were assessed. • Carcinogenic risks were considered as acceptable (<10{sup −6}). • For non-carcinogenic risks, only Sb exceeded a 10% of the HQ for dermal contact with clothes.

    In the present study we investigated whether the mental representation of the concept categories is represented by the container image schema (Lakoff & Johnson, 1980). In two experiments participants decided whether two pictures were from the same category (animal or vehicle). Pictures were presented inside or outside a frame that should activate the container schema. We found that performance to pictures was influenced by the frame in congruence with the metaphorical mapping (same category—inside bounded region; different category—not in same bounded region). These results show that the concept categories is metaphorically represented by containers.

    Full Text Available To better understand the reasons for the marketability of clothing now designed and sold in China and Japan, we asked Japanese and Chinese experts to evaluate Chinese and Japanese brands of clothing currently for sale in the Japanese market. The marketability of the Chinese apparel items in the Japanese market was evaluated by the Japanese experts. Five Japanese jackets were purchased from a department store in Tokyo, and ten items of Chinese clothing were purchased from a department store in Beijing. Five of the Chinese clothing samples were judged as impossible to sell in Japanese department stores primarily because the sewing quality was incompatible with Japanese requirements, the designs were outdated, and the materials were of low quality. However, the other five Chinese clothing samples received high evaluations of marketability in Japan. We found that Japanese experts focused on general design and sewing finish, while Chinese experts considered more general design points. Thus, our results indicate that clothing is evaluated differently in Japan and China. We conclude that it is necessary to consider the respective evaluation points used in each country as we pursue globalisation.

  15. Distinguishing between Perceiver and Wearer Effects in Clothing Color-Associated Attributions

    Directory of Open Access Journals (Sweden)

    S. Craig Roberts

    2010-07-01

    Full Text Available Recent studies have noted positive effects of red clothing on success in competitive sports, perhaps arising from an evolutionary predisposition to associate the color red with dominance status. Red may also enhance judgments of women's attractiveness by men, perhaps through a similar association with fertility. Here we extend these studies by investigating attractiveness judgments of both sexes and by contrasting attributions based on six different colors. Furthermore, by photographing targets repeatedly in different colors, we could investigate whether color effects are due to influences on raters or clothing wearers, by either withholding from raters information about clothing color or holding it constant via digital manipulation, while retaining color-associated variation in wearer's expression and posture. When color cues were available, we found color-attractiveness associations when males were judged by either sex, or when males judged females, but not when females judged female images. Both red and black were associated with higher attractiveness judgments and had approximately equivalent effects. Importantly, we also detected significant clothing color-attractiveness associations even when clothing color was obscured from raters and when color was held constant by digital manipulation. These results suggest that clothing color has a psychological influence on wearers at least as much as on raters, and that this ultimately influences attractiveness judgments by others. Our results lend support for the idea that evolutionarily-derived color associations can bias interpersonal judgments, although these are limited neither to effects on raters nor to the color red.

    Full Text Available Low-carbon is not only a slogan, but also a global action to protect the environment. In the clothing industry, low-carbon clothing design has drawn public focus and it also conveyed the notion that we should respect for nature and advocate the concept of conservation. Through the analysis and study of low-carbon clothing design, it comes to two conclusions: On the subjective aspect, low-carbon design consciousness of designers which humanization of costume design, design clothing beyond beauty, thinking and caring about people; on the objective aspects, low-carbon clothing design is analyzed in three main aspects: fabric, color and styling. It is necessary to put low-carbon concept into people’s behavior consciousness and let the slow fashion environmental concept return back to people’s fashion lifestyle, so that consumers can look for their self-positioning and rational thinking. Therefore, the design of low-carbon clothing should be raised to the design of humanistic care to ensure that low-carbon concept is a global need and responsibility.

  17. Comparative Analysis of the Thermal Insulation of Traditional and Newly Designed Protective Clothing for Foundry Workers

    Full Text Available An objective of the undertaken research was checking the applicability of aluminized basalt fabrics for the production of clothing for foundry workers. The results of flammability, the resistance to contact, convective and radiation heat, as well as the resistance to big molten metal splashes confirmed the thesis of applicability of the packages with the use of aluminized basalt fabric content for the assumed purpose; therefore, such protective clothing was produced. Thermal comfort of foundry workers is very important and related to many factors, i.e., the structure of the protective clothing package, the number of layers, their thickness, the distance between the body and appropriate underwear. In the paper, a comparison of the results of thermal insulation measurement of two kinds of protective clothing is presented: the traditional one made of aluminized glass fabrics and the new one made of aluminized basalt fabrics. Measurements of clothing thermal insulation were conducted using a thermal manikin dressed in the protective clothing and three kinds of underwear products covering the upper and lower part of the manikin.

    Military and civil defense personnel are often involved in complex activities in a variety of outdoor environments. The choice of appropriate clothing ensembles represents an important strategy to establish the success of a military mission. The main aim of this study was to compare the known clothing insulation of the garment ensembles worn by soldiers during two winter outdoor field trials (hike and guard duty) with the estimated optimal clothing thermal insulations recommended to maintain thermoneutrality, assessed by using two different biometeorological procedures. The overall aim was to assess the applicability of such biometeorological procedures to weather forecast systems, thereby developing a comprehensive biometeorological tool for military operational forecast purposes. Military trials were carried out during winter 2006 in Pokljuka (Slovenia) by Slovene Armed Forces personnel. Gastrointestinal temperature, heart rate and environmental parameters were measured with portable data acquisition systems. The thermal characteristics of the clothing ensembles worn by the soldiers, namely thermal resistance, were determined with a sweating thermal manikin. Results showed that the clothing ensemble worn by the military was appropriate during guard duty but generally inappropriate during the hike. A general under-estimation of the biometeorological forecast model in predicting the optimal clothing insulation value was observed and an additional post-processing calibration might further improve forecast accuracy. This study represents the first step in the development of a comprehensive personalized biometeorological forecast system aimed at improving recommendations regarding the optimal thermal insulation of military garment ensembles for winter activities.

    Ergonomic measurement is central to product design and development; especially for body worn products and clothing. However, there is a large variation in measurement definitions, complicated by new body scanning technology that captures measurements in a posture different to traditional manual methods. Investigations of hip measurement definitions in current clothing measurement practices supports analysis of the effect of scan posture and hip measurement definition on the circumferences of the hip. Here, the hip girth is a key clothing measurement that is not defined in current body scanning measurement standards. Sixty-four participants were scanned in the standard scan posture of a [TC](2) body scanner, and also in a natural posture similar to that of traditional manual measurement collection. Results indicate that scan posture affects hip girth circumferences, and that some current clothing measurement practices may not define the largest lower body circumference. Recommendations are made concerning how the hip is defined in measurement practice and within body scanning for clothing product development. Practitioner Summary: The hip girth is an important measurement in garment design, yet its measurement protocol is not currently defined. We demonstrate that body posture during body scanning affects hip circumferences, and that current clothing measurement practices may not define the largest lower body circumference. This paper also provides future measurement practice recommendations.

    Full Text Available At first glance clothes are obviously made by cutting and sewing. The textile fabric is cut in different shapes and reassembled by sewing in the wanted shape and volume. Sometimes the structures can be quite complex. The truth is that there are more ways of making clothes, as we can see looking back into the history of fashion. The progress of technology in textile industry offers also very interesting directions that we could not dream about some time ago. Observing carefully the economy of seams, their presence, absence or the suitable number can move us towards creative solutions that are relevant not only for the esthetic of a garment but also for the process of making clothes suggesting alternatives for the present situation and its important problems like sustainability. This paper is a survey of alternative ways in making clothes and highlights the relation between concept and practical issues. The starting point is seamless clothing and the natural fascination of the subject. Going further on this line we should consider that the absence of the seams in a garment is not the same with a seamless appearance. So, do we really need to sew our clothes?

    Occupational population-based epidemiological data relating to occupational contact allergies in the Chinese clothing industry are limited. To investigate the prevalence of occupational allergic contact dermatitis (OACD) and to identify the causative allergens among clothing employees in China, a cross-sectional study was conducted in 529 clothing employees at 12 clothing factories in Beijing. All employees were subjected to an interview using self-administered questionnaire and skin examination, and those who were diagnosed with occupational contact dermatitis (OCD) were patch tested. In the present survey, we found that the overall 1-year prevalence of OACD among the clothing employees was 8.5%. The 1-year prevalence of OACD among workers (10.8%) was significantly higher than that among managers (3.2%). The lesions were primarily on the hands and wrists in workers, but the face and neck in managers. The major allergens were nickel sulfate and cobalt dichloride in workers and colophony and p-tert-butylphenol formaldehyde resin in managers. In conclusion, workers are at a higher risk of OACD compared with managers in the Chinese clothing industry. In addition to hand dermatitis in workers, airborne contact dermatitis on the face and neck should be also addressed in managers.

    2016-01-01

    The potential for para-occupational, domestic, or take-home exposures from asbestos-contaminated work clothing has been acknowledged for decades, but historically has not been quantitatively well characterized. A simulation study was performed to measure airborne chrysotile concentrations associated with laundering of contaminated clothing worn during a full shift work day. Work clothing fitted onto mannequins was exposed for 6.5 h to an airborne concentration of 11.4 f/cc (PCME) of chrysotile asbestos, and was subsequently handled and shaken. Mean 5-min and 15-min concentrations during active clothes handling and shake-out were 3.2 f/cc and 2.9 f/cc, respectively (PCME). Mean airborne PCME concentrations decreased by 55% 15 min after clothes handling ceased, and by 85% after 30 min. PCM concentrations during clothes handling were 11-47% greater than PCME concentrations. Consistent with previously published data, daily mean 8-h TWA airborne concentrations for clothes-handling activity were approximately 1.0% of workplace concentrations. Similarly, weekly 40-h TWAs for clothes handling were approximately 0.20% of workplace concentrations. Estimated take-home cumulative exposure estimates for weekly clothes handling over 25-year working durations were below 1 f/cc-year for handling work clothes contaminated in an occupational environment with full shift airborne chrysotile concentrations of up to 9 f/cc (8-h TWA).

  8. Personal Protection of Permethrin-Treated Clothing against Aedes aegypti, the Vector of Dengue and Zika Virus, in the Laboratory.

    Full Text Available The dengue and Zika viruses are primarily transmitted by Aedes aegypti mosquitoes, which are most active during day light hours and feed both in and outside of the household. Personal protection technologies such as insecticide-treated clothing could provide individual protection. Here we assessed the efficacy of permethrin-treated clothing on personal protection in the laboratory.The effect of washing on treated clothing, skin coverage and protection against resistant and susceptible Ae. aegypti was assessed using modified WHO arm-in-cage assays. Coverage was further assessed using free-flight room tests to investigate the protective efficacy of unwashed factory-dipped permethrin-treated clothing. Clothing was worn as full coverage (long sleeves and trousers and partial coverage (short sleeves and shorts. Residual permethrin on the skin and its effect on mosquitoes was measured using modified WHO cone assays and quantified using high-pressure liquid chromatography (HPLC analysis.In the arm-in-cage assays, unwashed clothing reduced landing by 58.9% (95% CI 49.2-66.9 and biting by 28.5% (95% CI 22.5-34.0, but reduced to 18.5% (95% CI 14.7-22.3 and 11.1% (95% CI 8.5-13.8 respectively after 10 washes. Landing and biting for resistant and susceptible strains was not significantly different (p80% one hour after wearing treated clothing.Whilst partially covering the body with permethrin-treated clothing provided some protection against biting, wearing treated clothing with long sleeves and trousers provided the highest form of protection. Washing treated clothing dramatically reduced protection provided. Permethrin-treated clothing could provide protection to individuals from Ae. aegypti that show permethrin resistance. Additionally, it could continue to provide protection even after the clothing has been worn. Field trials are urgently needed to determine whether clothing can protect against dengue and Zika.

    The presence and intensity of red coloration correlate with male dominance and testosterone in a variety of animal species, and even artificial red stimuli can influence dominance interactions. In humans, red stimuli are perceived as more threatening and dominant than other colours, and wearing red increases the probability of winning sporting contests. We investigated whether red clothing biases the perception of aggression and dominance outside of competitive settings, and whether red influences decoding of emotional expressions. Participants rated digitally manipulated images of men for aggression and dominance and categorized the emotional state of these stimuli. Men were rated as more aggressive and more dominant when presented in red than when presented in either blue or grey. The effect on perceived aggression was found for male and female raters, but only male raters were sensitive to red as a signal of dominance. In a categorization test, images were significantly more often categorized as ‘angry’ when presented in the red condition, demonstrating that colour stimuli affect perceptions of emotions. This suggests that the colour red may be a cue used to predict propensity for dominance and aggression in human males. PMID:25972401

This suggests that the colour red may be a cue used to predict propensity for dominance and aggression in human males. © 2015 The Author(s) Published by the Royal Society. All rights reserved.

    The permeation of methylene chloride and perchloroethylene through seven protective clothing materials was studied to determine the permeation parameters, and to investigate the effect of solubility (polymer weight gain) and material thickness on the permeation parameters. The materials tested were two different nitrile rubbers, neoprene, Combination (a blend of natural rubber, neoprene and nitrile), two different polyvinyl chlorides, and polyvinyl alcohol. Methylene chloride permeated through all materials, except PVA, with breakthrough times in the range of 2 to 8 min, and permeation rates in the range of 1250-5800 micrograms/cm2 X min. PVA and unsupported nitrile offered good protection against perchloroethylene with breakthrough time occurring after 2 hr. Perchloroethylene permeated through the other materials with breakthrough times in the range of 8 to 36 min and permeation rates in the range of 200 to 1600 micrograms/cm2 X min. It was shown that for both chemicals, there is a correlation between the solubility (weight gain) and the ratio of permeation rate to breakthrough time (PR/BT). For all material/chemical pairs, an increase in solubility, increased (PR/BT). The change in material thickness had an effect on breakthrough time and permeation rate, but no effect on normalized breakthrough time. An increase in thickness reduced permeation rate and increased breakthrough time.

    Full Text Available In this paper are presented the phases for improving from an aesthetic point of view a clothing item, the T-shirt for women using software design patterns, computerised graphics and textile different modern technologies including: industrial embroidery, digital printing, sublimation. In the first phase a documentation was prepared in the University of Oradea and traditional motif was selected from a collection comprising a number of Romanian traditional motifs from different parts of the country and were reintepreted and stylized whilst preserving the symbolism and color range specified to the area. For the styling phase was used CorelDraw vector graphics program that allows changing the shape, size and color of the drawings without affecting the identity of the pattern. The embroidery was done using BERNINA Embroidery Software Designer Plus Software. This software allows you to export the model to any domestic or industrial embroidery machine regardless of brand. Finally we observed the resistance of the printed and embroided model to various: elasticity, resistance to abrasion and a sensory analysis on the preservation of color. After testing we noticed the imprint resistance applied to the fabric, resulting in a quality that makes possible to keep the Romanian traditional motif from generation to generation.

    Full Text Available This manuscript presents the design and construction of the energy efficient, time saving, cost effective of passive solar powered clothes dryer. This manuscript begins with a derivation of mathematical model represents of solar dryer followed with an analysis of the elements necessary for successfully designing the various components of a solar dryer. The solar drying performance achieved an average drying rate of 0.35 kg/h and drying time of 3 h in a typical day, even under local low ambient humidity of around 35% and at moderate outdoor wind speed. Also, the computational fluid dynamic CFD of transient thermal behavior based on Navier-Stokes equations was used to demonstrate the prevailing temperature rises in the solar natural-ventilation system associated with the internal heat flux due to solar radiation and moisture removal. The efficiency of solar dryer was improved using Nano coating technology. The result showed good agreement between the computational solid simulation and the experimental measurements obtained from this system.

    Full Text Available The integration of electronic devices and sensors into textiles has many different potential applications. Textile fabrics, from clothing to upholstery and home textiles, are an integral part of daily life and the ability to combine electronics into textiles means that a huge range of valuable data can be collected and used by the wearer to monitor their health, performance and wellbeing, among other uses. One of the most pressing challenges is that of interconnecting electronic components via the textile fibres in a robust and reliable way. Another aspect to be studied is the ability for the electronics to be connected and disconnected when necessary; for example, when charging the batteries or washing the garment. It is this aspect that has been considered by this development to facilitate ease-of-use among the older people. In addition, the complete package must be comfortable enough not to restrict movement, and must be unobtrusive so as to avoid any embarrassment to the wearer. The present paper presents a new solution for the connection of electronic measuring and monitoring devices to textile sensors to monitor variables such as movement, temperature, heart rate and breathing.

    Full Text Available The article stresses the relationship between Explicit and Implicit theories of Intelligence. Following the line of common sense epistemology and the theory of Social Representations, a study was carried out in order to analyze naive’s explanations about Intelligence Definitions. Based on Mugny & Carugati (1989 research, a self-administered questionnaire was designed and filled in by 286 subjects. Results are congruent with the main hyphotesis postulated: A general overlap between explicit and implicit theories showed up. According to the results Intelligence appears as both, a social attribute related to social adaptation and as a concept defined in relation with contextual variables similar to expert’s current discourses. Nevertheless, conceptions based on “gifted ideology” still are present stressing the main axes of Intelligence debate: biological and sociological determinism. In the same sense, unfamiliarity and social identity are reaffirmed as organizing principles of social representation. The distance with the object -measured as the belief in intelligence differences as a solve/non solve problem- and the level of implication with the topic -teachers/no teachers- appear as discriminating elements at the moment of supporting specific dimensions.

    Full Text Available This paper addresses the problem of supporting the software development process through the artificial intelligence. The expert systems could advise the Domain Engineer in programming without the detailed experience in programming languages. He will use and integrate, with the help of deductive database and domain knowledge, the previously developed software components to new complex functionalities. The objective of this document is to provide the knowledge representation about atomic Web Services which will be registered as the facts in the deductive database. The author proposes to use the decision rules in decision tables for representing the service model which consists of semantic specification, interface description, service quality (QoS, non-functional properties. Also the use of Domain Specific Languages (DSL for modeling Domain Engineers re-quests to the expert system will be considered within this document. As the illustrative use case for described knowledge representation the author proposes the domain of SOA-based geographic information systems (GIS which represent a new branch of information and communication technologies.

    The accurate determination of dust levels on optical surfaces is necessary to assess sensor system performance. A comparison study was made on several particle measurement methods including those based on direct imaging and light scattering. The effectiveness of removing the particles from the surface prior to determining particle size distributions was also assessed. These studies revealed that some methods, especially those requiring particle removal before analysis, are subject to large systematic errors affecting particle size distributions. Thus, an understanding of the particle measurement methods employed is necessary before any surface cleanliness or obstruction value assignments are accepted as true representations of an optical surface contamination condition.

    We use the idea of the symmetry between the spacetime coordinates xμ and the energy-momentum pμ in quantum theory to construct a momentum space quantum gravity geometry with a metric sμν and a curvature tensor Pλ μνρ. For a closed maximally symmetric momentum space with a constant 3-curvature, the volume of the p-space admits a cutoff with an invariant maximum momentum a. A Wheeler-DeWitt-type wave equation is obtained in the momentum space representation. The vacuum energy density and the self-energy of a charged particle are shown to be finite, and modifications of the electromagnetic radiation density and the entropy density of a system of particles occur for high frequencies.

    People adapt to thermal environments, such as the changing seasons, predominantly by controlling the amount of clothing insulation, usually in the form of the clothing that they wear. The aim of this study was to determine the actual daily clothing insulation on sedentary human subjects across the seasons. Thirteen females and seven males participated in experiments from January to December in a thermal chamber. Adjacent months were grouped in pairs to give six environmental conditions: (1) January/February = 5°C; (2) March/April = 14°C; (3) May/June = 25°C; (4) July/August = 29°C; (5) September/October = 23°C; (6) November/December = 8°C. Humidity(45 ± 5%) and air velocity(0.14 ± 0.01 m/s) were constant across all six experimental conditions. Participants put on their own clothing that allowed them to achieve thermal comfort for each air temperature, and sat for 60 min (1Met). The clothing insulation (clo) required by these participants had a significant relationship with air temperature: insulation was reduced as air temperature increased. The range of clothing insulation for each condition was 1.87-3.14 clo at 5°C(Jan/Feb), 1.62-2.63 clo at 14°C(Mar/Apr), 0.87-1.59 clo at 25°C(May/Jun), 0.4-1.01 clo at 29°C(Jul/Aug), 0.92-1.81 clo at 23°C (Sept/Oct), and 2.12-3.09 clo at 8°C(Nov/Dec) for females, and 1.84-2.90 clo at 5°C, 1.52-1.98 clo at 14°C, 1.04-1.23 clo at 25°C, 0.51-1.30 clo at 29°C, 0.82-1.45 clo at 23°C and 1.96-3.53 clo at 8°C for males. The hypothesis was that thermal insulation of free living clothing worn by sedentary Korean people would vary across seasons. For Korean people, a comfortable air temperature with clothing insulation of 1 clo was approximately 27°C. This is greater than the typical comfort temperature for 1 clo. It was also found that women clearly increased their clothing insulation level of their clothing as winter approached but did not decrease it by the same amount when spring came.
