    Several research strategies have been used to study the pathogenesis of alcoholic hepatitis (AH). These strategies have shown that various signaling pathways are the target of alcohol in liver cells. However, few have provided specific mechanisms associated with Mallory-Denk Bodies (MDBs) formed in Balloon cells in AH. The formation of MDBs in these hepatocytes is an indication that the mechanisms of protein quality control have failed. The MDB is the result of aggregation and accumulation of proteins in the cytoplasm of balloon degenerated liver cells. To understand the mechanisms that failed to degrade and remove proteins in the hepatocyte from patients suffering from alcoholic hepatitis, we investigated the pathways that showed significant up regulation in the AH liver biopsies compared to normal control livers (Liu et al., 2015). Analysis of genomic profiles of AH liver biopsies and control livers by RNA-seq revealed different pathways that were up regulated significantly. In this study, the focus was on Tec kinase signaling pathways and the genes that significantly interrupt this pathway. Quantitative PCR and immunofluorescence staining results, indicated that several genes and proteins are significantly over expressed in the livers of AH patients that affect the Tec kinase signaling to PI3K which leads to activation of Akt and its downstream effectors.

    Mallory-Denk bodies (MDBs) are aggresomes composed of undigested ubiqutinated short lived proteins which have accumulated because of a decrease in the rate of their degradation by the 26s proteasome. The decrease in the activity of the proteasome is due to a shift in the activity of the 26s proteasome to the immunoproteasome triggered by an increase in expression of the catalytic subunits of the immunoproteasome which replaces the catalytic subunits of the 26s proteasome. This switch in the type of proteasome in liver cells is triggered by the binding of IFNγ to the IFNγ sequence response element (ISRE) located on the FAT10 promoter. To determine if either FAT10 or IFNγ are essential for the formation of MDBs we fed both IFNγ and FAT10 knock out (KO) mice DDC added to the control diet for 10 weeks in order to induce MDBs. Mice fed the control diet and Wild type mice fed the DDC or control diet were compared. MDBs were located by immunofluorescent double stains using antibodies to ubiquitin to stain MDBs and FAT10 to localize the increased expression of FAT10 in MDB forming hepatocytes. We found that MDB formation occurred in the IFNγ KO mice but not in the FAT10 KO mice. Western blots showed an increase in the ubiquitin smears and decreases β 5 (chymotrypsin-like 26S proteasome subunit) in the Wild type mice fed DDC but not in the FAT10 KO mice fed DDC. To conclude, we have demonstrated that FAT10 is essential to the induction of MDB formation in the DDC fed mice. PMID:22981937

    Bernhard Zatloukal

    Full Text Available The in situ proximity ligation assay (isPLA is an increasingly used technology for in situ detection of protein interactions, post-translational modifications, and spatial relationships of antigens in cells and tissues, in general. In order to test its performance we compared isPLA with immunofluorescence microscopy by analyzing protein interactions in cytoplasmic protein aggregates, so-called Mallory Denk bodies (MDBs. These structures represent protein inclusions in hepatocytes typically found in human steatohepatitis and they can be generated in mice by feeding of 3,5-diethoxy-carbonyl-1,4-dihydrocollidine (DDC. We investigated the colocalization of all three key MDB components, namely keratin 8 (K8, keratin 18 (K18, and p62 (sequestosome 1 by isPLA and immunofluorescence microscopy. Sensitivity and specificity of isPLA was assessed by using Krt8-/- and Krt18-/- mice as biological controls, along with a series of technical controls. isPLA signal visualization is a robust technology with excellent sensitivity and specificity. The biological relevance of signals generated critically depends on the performance of antibodies used, which requires careful testing of antibodies like in immunofluorescence microscopy. There is a clear advantage of isPLA in visualizing protein co-localization, particularly when antigens are present at markedly different concentrations. Furthermore, isPLA is superior to confocal microscopy with respect to spatial resolution of colocalizing antigens. Disadvantages compared to immunofluorescence are increased costs and longer duration of the laboratory protocol.

    Methods of forming aluminum oxynitride (AlON) materials include sintering green bodies comprising aluminum orthophosphate or another sacrificial material therein. Such green bodies may comprise aluminum, oxygen, and nitrogen in addition to the aluminum orthophosphate. For example, the green bodies may include a mixture of aluminum oxide, aluminum nitride, and aluminum orthophosphate or another sacrificial material. Additional methods of forming aluminum oxynitride (AlON) materials include sintering a green body including a sacrificial material therein, using the sacrificial material to form pores in the green body during sintering, and infiltrating the pores formed in the green body with a liquid infiltrant during sintering. Bodies are formed using such methods.

    The severe fever with thrombocytopenia syndrome virus (SFTSV) is a new member in the genus Phlebovirus of the family Bunyaviridae identified in China. The SFTSV is also the causative pathogen of an emerging infectious disease: severe fever with thrombocytopenia syndrome. Using immunofluorescent staining and confocal microscopy, the intracellular distribution of nucleocapsid protein (NP) in SFTSV-infected THP-1 cells was investigated with serial doses of SFTSV at different times after infection. Transmission electron microscopy was used to observe the ultrafine intracellular structure of SFTSV-infected THP-1 cells at different times after infection. SFTSV NP could form intracellular inclusion bodies in infected THP-1 cells. The association between NP-formed inclusion bodies and virus production was analyzed: the size of the inclusion body formed 3 days after infection was correlated with the viral load in supernatants collected 7 days after infection. These findings suggest that the inclusion bodies formed in SFTSV-infected THP-1 cells could be where the SFTSV uses host-cell proteins and intracellular organelles to produce new viral particles.

  9. Yeast prions form infectious amyloid inclusion bodies in bacteria

    2012-06-01

    Full Text Available Abstract Background Prions were first identified as infectious proteins associated with fatal brain diseases in mammals. However, fungal prions behave as epigenetic regulators that can alter a range of cellular processes. These proteins propagate as self-perpetuating amyloid aggregates being an example of structural inheritance. The best-characterized examples are the Sup35 and Ure2 yeast proteins, corresponding to [PSI+] and [URE3] phenotypes, respectively. Results Here we show that both the prion domain of Sup35 (Sup35-NM and the Ure2 protein (Ure2p form inclusion bodies (IBs displaying amyloid-like properties when expressed in bacteria. These intracellular aggregates template the conformational change and promote the aggregation of homologous, but not heterologous, soluble prionogenic molecules. Moreover, in the case of Sup35-NM, purified IBs are able to induce different [PSI+] phenotypes in yeast, indicating that at least a fraction of the protein embedded in these deposits adopts an infectious prion fold. Conclusions An important feature of prion inheritance is the existence of strains, which are phenotypic variants encoded by different conformations of the same polypeptide. We show here that the proportion of infected yeast cells displaying strong and weak [PSI+] phenotypes depends on the conditions under which the prionogenic aggregates are formed in E. coli, suggesting that bacterial systems might become useful tools to generate prion strain diversity.

  10. Constraint, natural selection, and the evolution of human body form.

    Variation in body form among human groups is structured by a blend of natural selection driven by local climatic conditions and random genetic drift. However, attempts to test ecogeographic hypotheses have not distinguished between adaptive traits (i.e., those that evolved as a result of selection) and those that evolved as a correlated response to selection on other traits (i.e., nonadaptive traits), complicating our understanding of the relationship between climate and morphological distinctions among populations. Here, we use evolutionary quantitative methods to test if traits previously identified as supporting ecogeographic hypotheses were actually adaptive by estimating the force of selection on individual traits needed to drive among-group differentiation. Our results show that not all associations between trait means and latitude were caused by selection acting directly on each individual trait. Although radial and tibial length and biiliac and femoral head breadth show signs of responses to directional selection matching ecogeographic hypotheses, the femur was subject to little or no directional selection despite having shorter values by latitude. Additionally, in contradiction to ecogeographic hypotheses, the humerus was under directional selection for longer values by latitude. Responses to directional selection in the tibia and radius induced a nonadaptive correlated response in the humerus that overwhelmed its own trait-specific response to selection. This result emphasizes that mean differences between groups are not good indicators of which traits are adaptations in the absence of information about covariation among characteristics.

    Full Text Available Several studies have shown the distinct contribution of motion and form to the esthetic evaluation of female bodies. Here, we investigated how variations of implied motion and body size interact in the esthetic evaluation of female and male bodies in a sample of young healthy women. Participants provided attractiveness, beauty, and liking ratings for the shape and posture of virtual renderings of human bodies with variable body size and implied motion. The esthetic judgments for both shape and posture of human models were influenced by body size and implied motion, with a preference for thinner and more dynamic stimuli. Implied motion, however, attenuated the impact of extreme body size on the esthetic evaluation of body postures, and body size variations did not affect the preference for more dynamic stimuli. Results show that body form and action cues interact in esthetic perception, but the final esthetic appreciation of human bodies is predicted by a mixture of perceptual and affective evaluative components.

    Methods of forming composite materials include coating particles of titanium dioxide with a substance including boron (e.g., boron carbide) and a substance including carbon, and reacting the titanium dioxide with the substance including boron and the substance including carbon to form titanium diboride. The methods may be used to form ceramic composite bodies and materials, such as, for example, a ceramic composite body or material including silicon carbide and titanium diboride. Such bodies and materials may be used as armor bodies and armor materials. Such methods may include forming a green body and sintering the green body to a desirable final density. Green bodies formed in accordance with such methods may include particles comprising titanium dioxide and a coating at least partially covering exterior surfaces thereof, the coating comprising a substance including boron (e.g., boron carbide) and a substance including carbon.

    A retrospective observational study. This study examined the role of skeletal muscles in the spinal alignment of lumbar degenerative kyphosis (LDK). Adult spinal deformity (ASD) may present as LDK, which is unusual in that it typically lacks any coronal deformity. This retrospective study included 367 female patients with ASD. Demographic and radiographic data from LDKs were compared with those with other ASD. The LDK multifidus was also subjected to histological analysis. The muscle volume and strength were analyzed using whole-body dual x-ray absorptiometry and pulmonary function tests. Magnetic resonance images were used to determine the cross-sectional area (CSA) and fatty infiltration area (FIA) of the psoas and multifidus. A total of 52 patients (15%) were classified as LDK. Compared with other ASDs, those with LDK had a significantly larger sagittal vertical axis (16.3 ± 5.0 cm), and pelvic incidence minus lumbar lordosis (52.8° ± 9.2°). The LDK had significantly lower CSA and higher FIA of the multifidus, but not in the psoas (multifidus CSA 223 ± 96 vs. 477 ± 129 mm, P strength and volume of the other body sections were normal. These findings strongly suggest the presence of isolated lumbar extensor myopathy in LDK. 4.

    Full Text Available Being acquainted and well aware of the presence of physical deformation in school population, this study is based on the research of postural deformity of the pupils of the 5th grade of elementary school and determination of dependance of deformations appearance in relation to frequency of remonstration and indication to correct sitting position from proffesors’ perspective. The complete program content is conducted in the territory of the city of Kragujevac in several elementary schools comprising 299 students of the 5th grade. The object was to determine the number of students with kyphotic and lordotic deformity, to determine the presence of deformation in depandance of gender and to determine the presence of kyphotic and lordotic deformity in depandance of the frequency of proffesors indication to improper sitting. We can notice higher presence of kyphotic deformity at the probationers of male population that it is the case with female population while the higher presence of lordotic deformity is at female population.The highest number of probationers have reported that none of the proffesors warn them about proper sitting. The measures inside the groups sorted by gender qualifi cation, indicate on high percentage of both boys and girls who are not warned on proper sitting. Also, inside the groups of improper body holders, we can notice the most signifi cant kyphotic and lordotic deformity in the category of students who are never warned to sit properly. These indicators report us that is necessary to invest much more work on the education of parents and children as well as school stuff at the preschool and school institutions which would result in reducing the appearence and development of postural deformity at the population who is more liable to transformations of such kind.

  17. Form or function: Does focusing on body functionality protect women from body dissatisfaction when viewing media images?

    2018-01-01

    We examined whether shifting young women's ( N =322) attention toward functionality components of media-portrayed idealized images would protect against body dissatisfaction. Image type was manipulated via images of models in either an objectified body-as-object form or active body-as-process form; viewing focus was manipulated via questions about the appearance or functionality of the models. Social comparison was examined as a moderator. Negative outcomes were most pronounced within the process-related conditions (body-as-process images or functionality viewing focus) and for women who reported greater functionality comparison. Results suggest that functionality-based depictions, reflections, and comparisons may actually produce worse outcomes than those based on appearance.

    Attending to the material discursive constructions of the patient body within cone beam computed tomography (CBCT) imaging in radiotherapy treatments, in this paper I describe how bodies and machines co-create images. Using an analytical framework inspired by Science and Technology Studies and Feminist Technoscience, I describe the interplay between machines and bodies and the implications of materialities and agency. I argue that patients' bodies play a part in producing scans within acceptable limits of machines as set out through organisational arrangements. In doing so I argue that bodies are fabricated into the order of work prescribed and embedded within and around the CBCT system, becoming, not only the subject of resulting images, but part of that image. The scan is not therefore a representation of a passive subject (a body) but co-produced by the work of practitioners and patients who actively control (and contort) and discipline their body according to protocols and instructions and the CBCT system. In this way I suggest they are 'con-forming' the CBCT image. A Virtual Abstract of this paper can be found at: https://youtu.be/qysCcBGuNSM. © 2015 Foundation for the Sociology of Health & Illness.

    Full Text Available Dialectical reasoning in Jacques Ellul's critique of "autonomous'’ technologyJacques Ellul (1912-1994 is one of the most influential twentieth-century philosophers of technology. His critique of the “technological system ", characterized by him as an autonomous power which is on the brink of developing out of control, is original and all-encompassing Ellul maintains that the most important features of technology are that technology is a result of sin, that it has given rise to a technological system which constitutes an "autonomous" force with the attainment of efficiency as the basis of its ethics, and that it has enslaved man. In order to counter the advance of the system, Ellul advocates a Christian form o f non-violent anarchy. This form of resistance is designed to "desacralize" the technological system and is based on Ellul’s exegesis of certain Biblical passages. It is argued that Ellul tends to absolutize human freedom as well as the dialectical tension between man and technology, which he considers a precondition for human freedom. By contrasting Ellul's views with the Reformational position, it is shown that Ellul's conception of technology is inadequate, leading to an erroneous view of man's relation to technology and the meaning of technology.

    1987-01-01

    The history of total body irradiation and bone marrow transplantation is surprisingly old. Following the success of Thomas et al. in the 1970s, bone marrow transplantation appeared to be the sole curative treatment modality for high-risk leukemia. A supralethal dose of total body irradiation was widely accepted as a form of preparation for bone marrow transplantation. In this paper, I described the present status of bone marrow transplantation for leukemia patients in Japan based on the IVth national survey. Since interstitial pneumonitis was one of the most life threatening complications after bone marrow transplantation, I mentioned the dose, dose-rate and fraction of total body irradiation in more detail. In addition, I dealt with some problems of the total body irradiation, such as dose prescription, compensating contour as well as inhomogeneity, and shielding for the highrisk organs.

    H . J. Schutte

    1983-03-01

    Full Text Available In this article the author indicates how mathematical thought has exerted influence in various fields. The questions around the nature of mathematical knowledge and how this might be obtained had their foundation in philosophy. According to Plato man comes lo the truth by means of pure thought, independent of sensory perception. Bergson feels that truth if obtained through “intuition" and not by means of the intellect. Russel reduced mathematical truths to logical truths. According to him logical truths are true exclusively on the basis of the meanings adduced to words and sentences. The extreme criteria laid down by the logical positivists for the meaningfulness of a statement have led to the situation of statements such as “God exists" having no sense any more. Mathematical thought has exerted influence also via philosophy and the mathematical sciences on man’s sense of values and views on the meaning of human existence. The descript ion of man purely in terms of concepts, which was so successful in physics leads to superficiality in the concept of the meaning of human existence, and has alienated man from those things in which he had to find inspiration and tranquillity. The way to oppose nihilism lies in the fact that all aspects of reality and of being human have to he places in a balanced relationship and the correct perspective, and that all these have to be evaluated in the right light.

    A method of constructing a nozzle having cooling channels comprises a shell and a liner which are formed into a body of revolution having an axis of revolution. Helical welds are formed to hold the liner and shell to each other with a channel position being defined between each pair of helical welds. Pressurized fluid which may be a gas or a liquid, is introduced between the weld pairs to outwardly bulge the material of at least one of the liner and shell to define the channels.

  6. Evolution of the snake body form reveals homoplasy in amniote Hox gene function.

    Head, Jason J; Polly, P David

    2015-04-02

    Hox genes regulate regionalization of the axial skeleton in vertebrates, and changes in their expression have been proposed to be a fundamental mechanism driving the evolution of new body forms. The origin of the snake-like body form, with its deregionalized pre-cloacal axial skeleton, has been explained as either homogenization of Hox gene expression domains, or retention of standard vertebrate Hox domains with alteration of downstream expression that suppresses development of distinct regions. Both models assume a highly regionalized ancestor, but the extent of deregionalization of the primaxial domain (vertebrae, dorsal ribs) of the skeleton in snake-like body forms has never been analysed. Here we combine geometric morphometrics and maximum-likelihood analysis to show that the pre-cloacal primaxial domain of elongate, limb-reduced lizards and snakes is not deregionalized compared with limbed taxa, and that the phylogenetic structure of primaxial morphology in reptiles does not support a loss of regionalization in the evolution of snakes. We demonstrate that morphometric regional boundaries correspond to mapped gene expression domains in snakes, suggesting that their primaxial domain is patterned by a normally functional Hox code. Comparison of primaxial osteology in fossil and modern amniotes with Hox gene distributions within Amniota indicates that a functional, sequentially expressed Hox code patterned a subtle morphological gradient along the anterior-posterior axis in stem members of amniote clades and extant lizards, including snakes. The highly regionalized skeletons of extant archosaurs and mammals result from independent evolution in the Hox code and do not represent ancestral conditions for clades with snake-like body forms. The developmental origin of snakes is best explained by decoupling of the primaxial and abaxial domains and by increases in somite number, not by changes in the function of primaxial Hox genes.

    The effective-operator form of many-body theory is reviewed and applied to the calculation of the hyperfine structure. Numerical results are given for the 2p, 3p, and 4p excited states of Li and the 3p state of Na. This is the first complete calculation of the hyperfine structure using an effective-operator form of perturbation theory. As in the Brueckner-Goldstone form of many-body theory, the various terms in the perturbation expansion are represented by Feynman diagrams which correspond to basic physical processes. The angular part of the perturbation diagrams are evaluated by taking advantage of the formal analogy between the Feynman diagrams and the angular-momentum diagrams, introduced by Jucys et al. The radial part of the diagrams is calculated by solving one- and two-particle equations for the particular linear combination of excited states that contribute to the Feynman diagrams. In this way all second- and third-order effects are accurately evaluated without explicitly constructing the excited orbitals. For the 2p state of Li our results are in agreement with the calculations of Nesbet and of Hameed and Foley. However, our quadrupole calculation disagrees with the work of Das and co-workers. The many-body results for Li and Na are compared with semiempirical methods for evaluating the quadrupole moment from the hyperfine interaction, and a new quadrupole moment of 23 Na is given

    Human exposure to uranium increasingly becomes a subject of interest in many scientific disciplines such as environmental medicine, toxicology, and radiation protection. Knowledge about uranium chemical binding forms(speciation) in human body fluids can be of great importance to understand not only its biokinetics but also its relevance in risk assessment and in designing decorporation therapy in the case of accidental overexposure. In this study, thermodynamic calculations of uranium speciation in relevant simulated and original body fluids were compared with spectroscopic data after ex-situ uranium addition. For the first time, experimental data on U(VI) speciation in body fluids (saliva, sweat, urine) was obtained by means of cryogenic time-resolved laser-induced fluorescence spectroscopy (cryo-TRLFS) at 153 K. By using the time dependency of fluorescence decay and the band positions of the emission spectra, various uranyl complexes were demonstrated in the studied samples. The variations of the body fluids in terms of chemical composition, pH, and ionic strength resulted in different binding forms of U(VI). The speciation of U(VI) in saliva and in urine was affected by the presence of bioorganic ligands, whereas in sweat, the distribution depends mainly on inorganic ligands. We also elucidated the role of biological buffers, i.e., phosphate (H(2)PO(4−)/HPO(4)(2−)) on U(VI) distribution, and the system Ca(2+)/UO(2)(2+)/PO(4)(3−) was discussed in detail in both saliva and urine. The theoretical speciation calculations of the main U(VI) species in the investigated body fluids were significantly consistent with the spectroscopic data. Laser fluorescence spectroscopy showed success and reliability for direct determination of U(VI) in such biological matrices with the possibility for further improvement.

    The human body is both the physical form inhabited by an individual “self” and the medium through which an individual engages with society. Hence the body both shapes and is shaped by an individual’s social roles. In contrast to the cognate fields of archaeology, anthropology, and classics, there has been little explicit discussion or theorization of the body in Egyptology. Some recent works, discussed here, constitute an exception to this trend, but there is much more scope for exploring anc...

    The purpose of this study is to expand the empirically derived wet bulb globe temperature (WBGT) index to a rational thermal index based on the heat balance for a human body. We derive the heat balance model in the same form as the WBGT for a human engaged in moderate intensity work with a metabolic heat production of 174W/m 2 while wearing typical vapor-permeable clothing under shady and sunny conditions. Two important relationships are revealed based on this derivation: (1) the natural wet bulb and black globe temperature coefficients in the WBGT coincide with the heat balance equation for a human body with a fixed skin wettedness of approximately 0.45 at a fixed skin temperature; and (2) the WBGT can be interpreted as the environmental potential to increase skin temperature rather than the heat storage rate of a human body. We propose an adjustment factor calculation method that supports the application of WBGT for humans dressed in various clothing types and working under various air velocity conditions. Concurrently, we note difficulties in adjusting the WBGT by using a single factor for humans wearing vapor-impermeable protective clothing. The WBGT for shady conditions does not need adjustment depending on the positive radiant field (i.e., when a radiant heat source exists), whereas that for the sunny condition requires adjustments because it underestimates heat stress, which may result in insufficient human protection measures.

    An important challenge in evolutionary biology is to understand how major changes in body form arise. The dramatic transition from a lizard-like to snake-like body form in squamate reptiles offers an exciting system for such research because this change is replicated dozens of times. Here, we use morphometric data for 258 species and a time-calibrated phylogeny to explore rates and patterns of body-form evolution across squamates. We also demonstrate how time-calibrated phylogenies may be used to make inferences about the time frame over which major morphological transitions occur. Using the morphometric data, we find that the transition from lizard-like to snake-like body form involves concerted evolution of limb reduction, digit loss, and body elongation. These correlations are similar across squamate clades, despite very different ecologies and >180 million years (My) of divergence. Using the time-calibrated phylogeny and ancestral reconstructions, we find that the dramatic transition between these body forms can occur in 20 My or less, but that seemingly intermediate morphologies can also persist for tens of millions of years. Finally, although loss of digits is common, we find statistically significant support for at least six examples of the re-evolution of lost digits in the forelimb and hind limb.

  16. Analysis tools for precision studies of hadronic three-body decays and transition form factors

    Schneider, Sebastian Philipp

    2013-02-14

    Due to the running coupling constant of Quantum Chromodynamics one of the pillars of the Standard Model, the strong interactions, is still insufficiently understood at low energies. In order to describe the interactions of hadrons that form in this physical regime, one has to devise methods that are non-perturbative in the strong coupling constant. In particular hadronic three-body decays and transition form factors present a great challenge due to the complex analytic structure ensued by strong final-state interactions. In this thesis we present two approaches to tackle these processes. In the first part we use a modified version of non-relativistic effective field theory to analyze the decay {eta}{yields}3{pi}. This perturbative low-energy expansion is ideally suited to study the effects of {pi}{pi} rescattering and contributes greatly to the understanding of the slope parameter of the {eta}{yields}3{pi}{sup 0} Dalitz plot, a quantity that is strongly influenced by final-state interactions and has presented a long-standing puzzle for theoretical approaches. In the second part we present dispersion relations as a non-perturbative means to study three-particle decays. Using the example of {eta}'{yields}{eta}{pi}{pi} we give a detailed introduction to the framework and its numerical implementation. We confront our findings with recent experimental data from the BES-III and VES collaborations and discuss whether the extraction of {pi}{eta} scattering parameters, one of the prime motives to study this decay channel, is feasible in such an approach. A more clear-cut application is given in our study of the decays {omega}/{phi}{yields}3{pi} due to the relative simplicity of this decay channel: our results are solely dependent on the {pi}{pi} P-wave scattering phase shift. We give predictions for the Dalitz plot distributions and compare our findings to very precise data on {phi}{yields}3{pi} by the KLOE and CMD-2 collaborations. We also predict Dalitz plot

    In column footing or semi-submergible type marine structures, a vertical wave force vanishes at a specific period of waves. This phenomenon is called wave-free characteristics. This wave-free characteristics make it possible to design marine structures superior in oscillation performance in waves. Since Bessho`s wave-free theory is useful only for an infinite water depth, this paper studied the wave-free theory for a shallow sea area. On a wave-free singularity and required floating body form, 2-D and 3-D axisymmetric floating body forms were determined, and vertical wave force characteristics of the obtained body forms were calculated and verified experimentally. Since the source term of the wave-free singularity was weaker in a shallow sea area than an infinite deep water area, resulting in the narrow width of the obtained wave-free body forms in a shallow sea area. The wave-free theory for a shallow sea area was verified by both numerical calculation based on a singularity distribution method and model experiment for these floating body forms. 3 refs., 10 figs.

    Body-image disturbance is a core aspect of eating disorders, yet the clinical manifestations of individuals' weight and shape concerns are complex, vary considerably, and are poorly understood by clinicians and researchers. This study aimed to distinguish different aspects of body-image disturbance-including weight/shape dissatisfaction, weight/shape overvaluation, weight/shape preoccupation, and fear of weight gain-in patients with binge-eating disorder (BED). Examining how each specific body image construct relates to biopsychosocial features of BED could contribute to the refinement of conceptualization and treatment planning. The current study assessed body-image disturbance and eating-disorder psychopathology in 748 treatment-seeking patients with BED using established investigator-based interviews reliably administered by doctoral clinicians. The 4 body image constructs, although related to one another, showed some important similarities in associations with biopsychosocial clinical features, as well as some important distinctions. The relation between overvaluation and self-esteem was, as conceptualized, more strongly negative than for other body image variables, and preoccupation was more associated than other body image variables with eating concerns. Biopsychosocial features of BED were associated with different forms of body-image disturbance, but associations of body image variables with body mass index (BMI) were not significant and associations with binge-eating frequency did not differ across body image variables. Manifestations of body-image disturbance in BED are complex and understanding the distinctions between different body image constructs can contribute to treatment formulation.

    Objective Endothelial colony-forming cells (ECFCs) are a subset of circulating endothelial progenitor cells that are particularly abundant in umbilical cord blood. We sought to determine whether ECFC abundance in cord blood is associated with maternal body-mass index (BMI) in non-pathological pregnancies. Study design We measured the level of ECFCs in the cord blood of neonates (n=27) born from non-obese healthy mothers with non-pathological pregnancies and examined whether ECFC abundance correlated with maternal BMI. We also examined the effect of maternal BMI on ECFC phenotype and function using angiogenic and vasculogenic assays. Results We observed variation in ECFC abundance among subjects and found a positive correlation between pre-pregnancy maternal BMI and ECFC content (r=0.51, P=0.007), which was independent of other obstetric factors. Despite this variation, ECFC phenotype and functionality were deemed normal and highly similar between subjects with maternal BMI <25 kg/m2 and BMI between 25–30 kg/m2, including the ability to form vascular networks in vivo. Conclusions This study underlines the need to consider maternal BMI as a potential confounding factor for cord blood levels of ECFCs in future comparative studies between healthy and pathological pregnancies. Endothelial colony-forming cells (ECFCs) are a subset of progenitor cells that circulate in peripheral blood and can give rise to endothelial cells (1,2), contributing to the formation of new vasculature and the maintenance of vascular integrity (3–5). The mechanisms that regulate the abundance of these cells in vivo remain poorly understood. ECFCs are rare in adult peripheral blood (1,2,10). In contrast, there is an elevated number of these cells in fetal blood during the third trimester of pregnancy (11–13). Emerging evidence indicates that deleterious conditions during fetal life can impair ECFC content and function. For instance, offspring of diabetic mothers have been shown to have

    Glycogen storage disease type IV (GSD IV) is an autosomal recessive disorder causing polyglucosan storage in various tissues. Neuromuscular forms present with fetal akinesia deformation sequence, lethal myopathy, or mild hypotonia and weakness. A 3-year-old boy presented with arthrogryposis, motor developmental delay, weakness, and rigid spine. Whole body MRI revealed fibroadipose muscle replacement but sparing of the sartorius, gracilis, adductor longus and vastus intermedialis muscles. Polyglucosan bodies were identified in muscle, and GBE1 gene analysis revealed two pathogenic variants. We describe a novel neuromuscular GSD IV phenotype and confirm the importance of muscle morphological studies in early onset neuromuscular disorders. Copyright © 2016. Published by Elsevier B.V.

    Fixed dystonia is a disabling disorder mainly affecting young women who develop fixed abnormal limb postures and pain after apparently minor peripheral injury. There is continued debate regarding its pathophysiology and management. We report 5 cases of fixed dystonia in patients who sought amputation of the affected limb. We place these cases in the context of previous reports of patients with healthy limbs and patients with chronic regional pain syndrome who have sought amputation. Our cases, combined with recent data regarding disorders of mental rotation in patients with fixed dystonia, as well as previous data regarding body integrity identity disorder and amputations sought by patients with chronic regional pain syndrome, raise the possibility that patients with fixed dystonia might have a deficit in body schema that predisposes them to developing fixed dystonia and drives some to seek amputation. The outcome of amputation in fixed dystonia is invariably unfavorable. Copyright © 2011 Movement Disorder Society.

    Current thought envisions dopamine neurons conveying the reinforcing effect of the unconditioned stimulus during associative learning to the axons of Drosophila mushroom body Kenyon cells for normal olfactory learning. Here, we show using functional GFP reconstitution experiments that Kenyon cells and dopamine neurons from axoaxonic reciprocal synapses. The dopamine neurons receive cholinergic input via nicotinic acetylcholine receptors from the Kenyon cells; knocking down these receptors impairs olfactory learning revealing the importance of these receptors at the synapse. Blocking the synaptic output of Kenyon cells during olfactory conditioning reduces presynaptic calcium transients in dopamine neurons, a finding consistent with reciprocal communication. Moreover, silencing Kenyon cells decreases the normal chronic activity of the dopamine neurons. Our results reveal a new and critical role for positive feedback onto dopamine neurons through reciprocal connections with Kenyon cells for normal olfactory learning.

    Full Text Available The main biological role of selenium is performed via enzyme glutathione peroxidase, and includes the participation in the defense mechanism of the cell membrane from the peroxide damage. The aim of this study was to determine the effect of added selenium in foods in varying amounts and from various sources (organic and inorganic selenium. The experiment was conducted on the broilers, and the following parameters were monitored: body weight, total serum protein and the activity of the liver enzymes AST and ALT. The study demonstrated that organically-bound selenium had the most pronounced protective property, while both forms of selenium did not significantly affect the growth and concentration of the total serum protein. Therefore, this research suggests economic benefits of organic selenium in the diet of broiler chickens. Key words: selenium, body weight, liver function, broiler chickens

    Recently the matrix of umbilical cord began to use as an alternative source of stem cells additionally to the blood of umbilical cord. Umbilical cord has been used mainly for mesenchymal stem cell banking. The immunological characteristics of mesenchymal stem cells in combination with their ability to avoid rejection make them an attractive biological material for transplantations. In this study the isolation of small in size pluripotent stem cells from umbilical cord expressing early transcription factors with characteristics that resemble to embryonic stem cells is investigated. Pluripotent stem cells were isolated from human umbilical cords, by a new strategy method based on unique characteristics such as the small size and the positivity on early transcription factors OCT and Nanog. An enriched population of CXCR4(+) OCT(+) Nanog(+) CD45(-) small stem cells from the cord was isolated. This fraction was able to create alkaline phosphatase positive like spheres forms in a mesenchymal layer with multilineage differentiation capacity. Our results were assessed by RT PCR and electophoresis for the pluripotent genes. These data suggest that umbilical cord provides an attractive source not only of mesenchymal stem cells but moreover of pluripotent stem cells. The method described herein should be applied in the field of stem cell banking in addition to the classical umbilical cord harvesting method. Isolation of a population of cells with pluripotent characteristics from umbilical cord. Adoption of a second centrifugation step for the pluripotent stem isolation.

    Mice were exposed in whole-body fashion to several doses of radiation and killed at various times thereafter for a determination of the number of background plaque-forming cells (PFCs) as assayed on either sheep erythrocytes or bromelain-treated autologous mouse erythrocytes. Increased numbers of both types of PFC were found in the irradiated groups. These increases were dependent on radiation dose and time after exposure. They did not appear to be caused by a disruption of normal lymphocyte traffic or a switch in immunoglobulin isotype. An increased number of PFCs on bromelain-treated mouse RBCs but not on sheep RBCs were found in irradiated congenitally athymic nude mice. On the basis of this and related observations, background PFCs on bromelain-treated mouse RBCs and on sheep RBCs appear to fall under different forms of homeostatic control

    Full Text Available Purpose: to find correlations between characteristics of body posture in the sagittal plane and fitness and endurance of first-form children from rural areas. Material: an analysis of more than 30 sources of scientific and educational literature. Results: the study involved 209 children, including 102 girls and 107 boys. They were children who lived in the country since they were born. To assess particular characteristics of body posture, the children were studied by means of the measuring equipment using the projection Moiré system. Motor skills were estimated using selected EUROFIT physical fitness tests (sitting forward bend, standing broad jump, handgrip, sit-and-reach, bent arm hang and 10 x 5 m shuttle run. The level of physical endurance was evaluated with the Harvard Step Test modified by Montoye. Conclusions: the conducted research reveals statistically significant correlations between the characteristics of body posture in the sagittal plane and selected EUROFIT physical fitness tests and physical endurance of the children involved in the study.

  15. The dynamics of pico-sized and bloom-forming cyanobacteria in large water bodies in the Mekong River Basin.

    Michio Fukushima

    Full Text Available In the face of plans for increased construction of dams and reservoirs in the Mekong River Basin, it is critically important to better understand the primary-producer community of phytoplankton, especially the warm-water cyanobacteria. This is because these algae can serve as the primary source of carbon for higher trophic levels, including fishes, but can also form harmful blooms, threatening local fisheries and environmental and human health. We monitored the dynamics of three cyanobacteria-Synechococcus spp., Microcystis aeruginosa, and Dolichospermum spp.-for two years in nine large lakes and reservoirs in the Mekong River Basin. The densities of these algae were largely system-specific such that their abundance was uniquely determined within individual water bodies. However, after accounting for the system-specific effect, we found that cell densities of Synechococcus spp., M. aeruginosa, and Dolichospermum spp. varied in response to changes in photosynthetically active radiation (PAR, total nitrogen, and water level, respectively. Because both PAR and water level tend to fluctuate concordantly over a wide geographic area, Synechococcus spp., and to a lesser extent Dolichospermum spp., varied synchronously among the water bodies. Sustaining the production of pico-sized primary producers while preventing harmful algal blooms will be a key management goal for the proposed reservoirs in the Mekong Basin.

  16. From lizard body form to serpentiform morphology: The atlas-axis complex in African cordyliformes and their relatives.

    Čerňanský, Andrej

    2016-04-01

    The comparative vertebral morphology of the atlas-axis complex in cordyliforms, xantusiid and several skinks is studied here. These lizards are particularly interesting because of their different ecological adaptations and anti-predation strategies, where conformation ranges from the lizard-like body to a snake-like body. This transition to serpentiform morphology shows several evolutionary patterns in the atlas-axis complex: 1) the zygapophyseal articulations are lost in the early stage of the transition. In contrast to mammals, the atlas is more or less locked to the axis in lepidosaurs, but the absence of zygapophyseal articulation releases this locking for rotation. However despite its serpentiform morphology, Chamaesaura is different, in possessing this articulation; 2) the first intercentrum of Chamaesaura and Tetradactylus africanus (serpentiform grass-swimmers) is fully curved anteriorly, underlying the occipital condyle. While this limits ventral skull rotation beyond a certain angle, it locks the skull, which is a crucial adaptation for a sit-and-wait position in grassland habitats that needs to keep the head stabilized; and 3) in Acontias, most of the atlas articular surface with the occipital condyle is formed by the lateral aspect of the articulation area relative to the area located in the dorsal region of the slightly reduced intercentrum. A similar state occurs in amphisbaenians, most likely reflecting a fossorial lifestyle of the limbless lizards. Although Chamaesaura and Tetradactylus live sympatrically in grasslands, Chamaesaura differs in several ways in atlas-axis complex: for example, aforementioned presence of the atlas-axis zygapophyseal articulation, and long posterodorsal processes. Its occipital condyle protrudes further posteriorly, placing the atlas-axis complex further from the endocranium than in Tetradactylus. Hence, adaptation in the same niche, even among sister clades, can lead to different atlas-axis morphology due to different

Such inclusions have variably been described as amorphous aggregates or more structured deposits having an amyloid structure. Following the observations that bacterial inclusion bodies generally consist of amyloid aggregates, we have overexpressed full-length TDP-43 and C-terminal TDP-43 in E. coli, purified the resulting full-length and C-terminal TDP-43 containing inclusion bodies (FL and Ct TDP-43 IBs and subjected them to biophysical analyses to assess their structure/morphology. We show that both FL and Ct TDP-43 aggregates contained in the bacterial IBs do not bind amyloid dyes such as thioflavin T and Congo red, possess a disordered secondary structure, as inferred using circular dichroism and infrared spectroscopies, and are susceptible to proteinase K digestion, thus possessing none of the hallmarks for amyloid. Moreover, atomic force microscopy revealed an irregular structure for both types of TDP-43 IBs and confirmed the absence of amyloid-like species after proteinase K treatment. Cell biology experiments showed that FL TDP-43 IBs were able to impair the viability of cultured neuroblastoma cells when added to their extracellular medium and, more markedly, when transfected into their cytosol, where they are at least in part ubiquitinated and phosphorylated. These data reveal an inherently high propensity of TDP-43 to form amorphous aggregates, which possess, however, an inherently high ability to cause cell dysfunction. This indicates that a gain of toxic function caused by TDP-43 deposits is effective in TDP-43 pathologies, in addition to possible loss of function mechanisms originating from the cellular mistrafficking of the protein.

    Purpose: Deformable registration of preoperative and intraoperative images facilitates accurate localization of target and critical anatomy in image-guided spine surgery. However, conventional deformable registration fails to preserve the morphology of rigid bone anatomy and can impart distortions that confound high-precision intervention. We propose a constrained registration method that preserves rigid morphology while allowing deformation of surrounding soft tissues. Method: The registration method aligns preoperative 3D CT to intraoperative cone-beam CT (CBCT) using free-form deformation (FFD) with penalties on rigid body motion imposed according to a simple intensity threshold. The penalties enforced 3 properties of a rigid transformation - namely, constraints on affinity (AC), orthogonality (OC), and properness (PC). The method also incorporated an injectivity constraint (IC) to preserve topology. Physical experiments (involving phantoms, an ovine spine, and a human cadaver) as well as digital simulations were performed to evaluate the sensitivity to registration parameters, preservation of rigid body morphology, and overall registration accuracy of constrained FFD in comparison to conventional unconstrained FFD (denoted uFFD) and Demons registration. Result: FFD with orthogonality and injectivity constraints (denoted FFD+OC+IC) demonstrated improved performance compared to uFFD and Demons. Affinity and properness constraints offered little or no additional improvement. The FFD+OC+IC method preserved rigid body morphology at near-ideal values of zero dilatation (D = 0.05, compared to 0.39 and 0.56 for uFFD and Demons, respectively) and shear (S = 0.08, compared to 0.36 and 0.44 for uFFD and Demons, respectively). Target registration error (TRE) was similarly improved for FFD+OC+IC (0.7 mm), compared to 1.4 and 1.8 mm for uFFD and Demons. Results were validated in human cadaver studies using CT and CBCT images, with FFD+OC+IC providing excellent preservation

    More than one third of patients with eating disorders report NSSI. Moreover, negative attitudes and feelings toward the body, body dissatisfaction, and body image disturbances have been linked to NSSI in community and clinical samples. However, there is a lack of studies exploring NSSI frequency and functions and the specific relationship between multidimensional body image dimensions and NSSI in eating disorder patients. First, we explored the frequency, types, and functions of NSSI in a sample of 226 Spanish female participants with eating disorders (ED). Second, we explored differences in NSSI and body image depending on the ED restrictive-purgative subtype; and third, we explored differences in body dissatisfaction, body image orientation, and body investment in eating disorder patients without NSSI (n = 144), with NSSI in their lifetime (n = 19), and (b) with NSSI in the previous year (n = 63). Of the overall sample, 37.1% (n = 89) had a history of self-injury during their lifetime, and 27.1% (n = 65) had self-injured in the previous year. Among the types of ongoing NSSI, the most frequent were banging (64.6%) and cutting (56.9%). Restrictive vs purgative patients differed on NSSI lifetime, Appearance Evaluation, Body Areas Satisfaction, Body Protection and Feelings and Attitudes toward the Body. Moreover, significant differences were found on Appearance Evaluation, Body Areas Satisfaction, Positive Feelings and Attitudes towards the Body, Body Protection, and Comfort with physical contact, between participants without a history of self-injury and both NSSI groups. Body dissatisfaction and body investment have been found to be variables related to NSSI. Thus, the present study highlights the importance of working on body image in ED patients to reduce the frequency of NSSI. Copyright © 2018 Elsevier Inc. All rights reserved.

    Weight management strategies have two components: weight goals and behaviors to reach weight goals. In the literature, weight goals and weight-related behaviors have both been linked with body dissatisfaction separately, but have rarely been examined simultaneously. This paper examines the associations between different forms of body dissatisfaction and various weight-related behaviors and investigates the moderating role of weight goals in these associations. Measures included weight goals (matching or mismatching current weight status), self-reported frequencies of use of weight-related behaviors, and a body dissatisfaction measure (strength of aspiring for weight gain or weight loss) from a representative population-based sample of adolescents (n = 2,346, 51 % female). Sex-specific multilevel logistic and ordinal regression analyses indicated that aspiring for a thinner body among girls was associated with more frequent use of healthy and unhealthy behaviors, whereas body dissatisfaction of any type among boys was linked to more frequent use of unhealthy behaviors. Girls aspiring for substantial weight loss and boys aspiring for substantial weight gain were more likely to use disordered health behaviors. Aiming for a goal that is mismatched with current weight status increases the use of unhealthy behaviors among body dissatisfied adolescents. We conclude that in order to elaborate interventions aimed at promoting health, research should focus on processes leading to specific forms of body dissatisfaction which in turn produce varying frequencies of use of weight-related behaviors.

    Body image is a psychological construct that refers to one's perceptions, feelings, and thoughts towards one's body and appearance. The intensity and frequency of dysphoric body-image emotions depend upon situational events (i.e., situations involving body exposure, social comparisons, wearing certain clothing, looking in the mirror, and so forth). The Situational Inventory of Body-Image Dysphoria-Short Form (SIBID-S; Cash, Manual for the situational inventory of body-image dysphoria, 2000) was originally developed to assess one's negative body-image emotions in certain situational events. The current study aimed to confirm the factor structure and reliability of the newly translated Greek version of the SIBID-S. Participants consisted of a convenient sample of 2664 high school students (1119 males, 1545 females) who answered the measures of interest. Results indicated that the original one-factor structure of the SIBID-S was retained and fitted very well with the original model for both males and females. In addition, the Greek version had satisfactory reliability and convergent validity coefficients. Gender differences were also noted. The Greek SIBID-S has very good validity and reliability data and will serve as a useful measure of body-image dysphoria enabling research with the Greek-speaking population as well as cross-cultural research.

    Within a relativistically correct yet analytically solvable model of light-front quantum mechanics we construct the electromagnetic form factor of the two-body bound state and we study the validity of the static approximation to the full form factor. Upon comparison of full form factors calculated for different values of binding energy we observe an unexpected effect that for very strongly bound states further increase in binding leads to an increase in the size of the bound system. A similar effect is found for another quantum-mechanical model of relativistic dynamics

    stress increases the frequency of chromosomal lesions that are transmitted to daughter cells. Throughout G1, these lesions are sequestered in nuclear compartments marked by p53-binding protein 1 (53BP1) and other chromatin-associated genome caretakers. We show that the number of such 53BP1 nuclear bodies...... increases after genetic ablation of BLM, a DNA helicase associated with dissolution of entangled DNA. Conversely, 53BP1 nuclear bodies are partially suppressed by knocking down SMC2, a condensin subunit required for mechanical stability of mitotic chromosomes. Finally, we provide evidence that 53BP1 nuclear...... bodies shield chromosomal fragile sites sequestered in these compartments against erosion. Together, these data indicate that restoration of DNA or chromatin integrity at loci prone to replication problems requires mitotic transmission to the next cell generations....

    2013-01-01

    The initial stages of in vitro differentiation of embryonic stem cells are considered as unique three-dimensional models of early development of mammals for basic, pharmacological, and toxicological studies. It has been previously shown (Gordeeva, 2012) that the assessment of embryotoxicity in the model of undifferentiated embryonic stem cells can be insufficiently accurate in predicting toxic effects on mammalian embryos. In view of this, we performed a comparative study of the damaging effects of the cytostatic etoposide in undifferentiated embryonic stem cells and embryoid bodiesof different stages of differentiation that have similar three-dimensional structures with early embryos. The analysis of growth, cell death, and dynamics of differentiation of embryonic stem cells and embryoid bodies exposed to etoposide showed that the cytostatic and cytotoxic effects of etoposide are stage-specific. The damaging effects of etoposide were maximum in the undifferentiated embryonic stem cells and decreased with growth and differentiation of embryoid bodies. We assume that the increase in the cell volume of embryoid bodies and the development of the hypertrophic we suggest that the increase of embryoid body volume and overgrowth of extraembryonic endoderm layer lead to a decrease in the diffusion, transport, and metabolism of chemical and bioactive substances and prevent the damaging effects.

    Phosphorus plays pivotal roles in the survival such as the cellular structure, genomic information, energy metabolism, and cell signaling. Total amount of phosphorus is 500-700 g in human, most of which is stored in the bone in an insoluble form of calcium salt. About 15% of phosphorus is located in the cell membrane and the intracellular fluid in the soft tissues in a form of organic phosphate. Only 0.1% is present in the extracellular fluid. This phosphate pool plays a role in the dynamic equilibrium through the gut, kidney, bone and other tissues. Most of inorganic phosphates in the extracellular fluid are present in a form of ions such as H2PO4- and HPO(4)2-, and the concentration of phosphatic acids is about 1.2 mM. The form, distribution, and physiological function of phosphorus in the body are summarized in this review.

    Fibrinogen storage disease (FSD) is a rare disorder that is characterized by the accumulation of fibrinogen in hepatocytes and induces liver injury. Six mutations in the γC domain (γG284R, γT314P, γD316N, the deletion of γG346-Q350, γG366S, and γR375W) have been identified for FSD. Our group previously established γ375W fibrinogen-producing Chinese hamster ovary (CHO) cells and observed aberrant large granular and fibrous forms of intracellular inclusion bodies. The aim of this study was to investigate whether fibrous intracellular inclusion bodies are specific to FSD-inducible variant fibrinogen. Thirteen expression vectors encoding the variant γ-chain were stably or transiently transfected into CHO cells expressing normal fibrinogen Aα- and Bβ-chains or HuH-7 cells, which were then immunofluorescently stained. Six CHO and HuH-7 cell lines that transiently produced FSD-inducible variant fibrinogen presented the fibrous (3.2-22.7 and 2.1-24.5%, respectively) and large granular (5.4-25.5 and 7.7-23.9%) forms of intracellular inclusion bodies. Seven CHO and HuH-7 cell lines that transiently produced FSD-non-inducible variant fibrinogen only exhibit the large granular form. These results demonstrate that transiently transfected variant fibrinogen-producing CHO cells and inclusion bodies of the fibrous form may be useful in non-invasive screening for FSD risk factors for FSD before its onset.

  8. Social intuition as a form of implicit learning: Sequences of body movements are learned less explicitly than letter sequences.

    In the current paper, we first evaluate the suitability of traditional serial reaction time (SRT) and artificial grammar learning (AGL) experiments for measuring implicit learning of social signals. We then report the results of a novel sequence learning task which combines aspects of the SRT and AGL paradigms to meet our suggested criteria for how implicit learning experiments can be adapted to increase their relevance to situations of social intuition. The sequences followed standard finite-state grammars. Sequence learning and consciousness of acquired knowledge were compared between 2 groups of 24 participants viewing either sequences of individually presented letters or sequences of body-posture pictures, which were described as series of yoga movements. Participants in both conditions showed above-chance classification accuracy, indicating that sequence learning had occurred in both stimulus conditions. This shows that sequence learning can still be found when learning procedures reflect the characteristics of social intuition. Rule awareness was measured using trial-by-trial evaluation of decision strategy (Dienes & Scott, 2005; Scott & Dienes, 2008). For letters, sequence classification was best on trials where participants reported responding on the basis of explicit rules or memory, indicating some explicit learning in this condition. For body-posture, classification was not above chance on these types of trial, but instead showed a trend to be best on those trials where participants reported that their responses were based on intuition, familiarity, or random choice, suggesting that learning was more implicit. Results therefore indicate that the use of traditional stimuli in research on sequence learning might underestimate the extent to which learning is implicit in domains such as social learning, contributing to ongoing debate about levels of conscious awareness in implicit learning.

  9. An explanation of forms of planetary orbits and estimation of angular shift of the Mercury' perihelion using the statistical theory of gravitating spheroidal bodies

    2013-09-01

    This work develops a statistical theory of gravitating spheroidal bodies to calculate the orbits of planets and explore forms of planetary orbits with regard to the Alfvén oscillating force [1] in the Solar system and other exoplanetary systems. The statistical theory of formation of gravitating spheroidal bodies has been proposed in [2]-[5]. Starting the conception for forming a spheroidal body inside a gas-dust protoplanetary nebula, this theory solves the problem of gravitational condensation of a gas-dust protoplanetary cloud with a view to planetary formation in its own gravitational field [3] as well as derives a new law of the Solar system planetary distances which generalizes the wellknown laws [2], [3]. This work also explains an origin of the Alfvén oscillating force modifying forms of planetary orbits within the framework of the statistical theory of gravitating spheroidal bodies [5]. Due to the Alfvén oscillating force moving solid bodies in a distant zone of a rotating spheroidal body have elliptic trajectories. It means that orbits for the enough remote planets from the Sun in Solar system are described by ellipses with focus in the origin of coordinates and with small eccentricities. The nearby planet to Sun named Mercury has more complex trajectory. Namely, in case of Mercury the angular displacement of a Newtonian ellipse is observed during its one rotation on an orbit, i.e. a regular (century) shift of the perihelion of Mercury' orbit occurs. According to the statistical theory of gravitating spheroidal bodies [2]-[5] under the usage of laws of celestial mechanics in conformity to cosmogonic bodies (especially, to stars) it is necessary to take into account an extended substance called a stellar corona. In this connection the stellar corona can be described by means of model of rotating and gravitating spheroidal body [5]. Moreover, the parameter of gravitational compression α of a spheroidal body (describing the Sun, in particular) has been

    The polyacrylamide gel electrophoresis (PAGE) was performed on the fat body tissues of the solitary form of the 5th nymph instar as well as three different phases of adult males and females namely newly emerged, yellow and non-yellow males (mature and nonmature), before oviposition and after oviposition females of Schistocerca gregaria. The total number of protein bands detected in the fat body of the 5th nymph instar amounted to 25 bands. Meanwhile, those detected in the fat body of newly emerged males, non-mature males and mature males were 22, 19, and 21 respectively. On the other hand, the numbers of protein bands detected in the newly emerged females were 28 bands. These bands varied in the successive female phases to be 21 and 30 bands before oviposition and after oviposition respectively. One protein band was detected in males only and considered as a male specific protein ( M-sp.) whereas, four bands were detected in females only and considered as female specific proteins ( F-sp.). Ten protein bands were considered as major fat body protein bands since they were commonly detected in all the investigated phases.

    We introduce parametrizations of hadronic three-body B and D weak decay amplitudes that can be readily implemented in experimental analyses and are a sound alternative to the simplistic and widely used sum of Breit-Wigner type amplitudes, also known as the isobar model. These parametrizations can be particularly useful in the interpretation of C P asymmetries in the Dalitz plots. They are derived from previous calculations based on a quasi-two-body factorization approach in which two-body hadronic final-state interactions are fully taken into account in terms of unitary S - and P -wave π π , π K , and K K ¯ form factors. These form factors can be determined rigorously, fulfilling fundamental properties of quantum field-theory amplitudes such as analyticity and unitarity, and are in agreement with the low-energy behavior predicted by effective theories of QCD. They are derived from sets of coupled-channel equations using T -matrix elements constrained by experimental meson-meson phase shifts and inelasticities, chiral symmetry, and asymptotic QCD. We provide explicit amplitude expressions for the decays B±→π+π-π±, B →K π+π-, B±→K+K-K±, D+→π-π+π+, D+→K-π+π+, and D0→KS0π+π-, for which we have shown in previous studies that this approach is phenomenologically successful; in addition, we provide expressions for the D0→KS0K+K- decay. Other three-body hadronic channels can be parametrized likewise.

    Johnson Space Center has archived thousands of astronauts acquired Earth images. Some spectacular images have been widely used in news media and in k-12 class room, but their potential utilizations in health promotion and disease prevention have relatively untapped. The project uses daytime ISS photographs to define city forms and links them to city or metropolitan level health data in a multicity context. Road connectivity, landuse mix and Shannon's information indices were used in the classification of photographs. In contrast to previous remote-sensing studies, which tend to focus on a single city or a portion of a city, this project utilized photographs of 39 U.S. cities. And in contrast to previous health-promotion studies on the built environment, which tend to rely on survey respondents' responses to evaluate road connectivity or mixed land use for a single study site, the project examined the built environments of multiple cities based on ISS photos. It was found that road connectivity and landuse mix were not statistically significant by themselves, but the composite measure of the Shannon index was significantly associated with physical activity, but not BMI. Consequently, leisure-time physical activity seems to be positively associated with the urban complexity scale. It was also concluded that unless they are planned or designed in advance, photographs taken by astronauts generally are not appropriate for a study of a single-site built environment nor are they appropriate for a study of infectious diseases at a local scale. To link urban built environment with city-wide health indicators, both the traditional nadir view and oblique views should be emphasized in future astronauts' earth observation photographs.

    Where and how did apocalyptic thought originate? Ancient cultures looked at the world as a changeless essence. A battle between good and evil, order and chaos is distinctive of the world. But the victory of good and order is guaranteed. At the turn of the second millennium BCE the proto-Indo-Iranians trekked from what today are the Steppes of Russia, through Caucasia to different destinations. The Vedic Indians established themselves in the rich Indus valley, while the other group settled in the east of what is the Iran of today. The Vedic Indians preserved the ancient doctrine of a changeless universe, while an Iranian prophet by the name of Zarathustra, often better known by the Greek version thereof, Zoroaster, started teaching that this world would come to an end. Zoroaster subscribed to the doctrine of a battle between good and evil but, for the first time in history formulated the belief that a final victory of good over evil would lead to a new earth and a new heaven.

Presenting the explicit dynamic equations also allows for more insight into the dynamic structure of the system. Another motivation is to correct some errors commonly found in the literature. Unfortunately, the formulation of the Boltzmann-Hamel equations used here are presented incorrectly. This has been corrected by the authors, but we present here, for the first time, the detailed mathematical details on how to arrive at the correct equations. We also show through examples that using the equations presented here, the dynamics of a single rigid body is reduced to the standard equations on a Lagrangian form, for example Euler's equations for rotational motion and Euler--Lagrange equations for free motion.

    The orientations of the kamacite lamellae formed from a single prior-taenite grain were measured by analysing the electron backscatter diffraction patterns obtained using scanning electron microscopy. These are shown to be close to the Kurdjumov-Sachs and Nishiyama-Wassermann relations and their intermediate, i.e., the Greninger-Troiano relation. The orientations of the α grains in the plessite regions were also measured and these were found to be continuously distributed around the Bain circles formed by the variants of the common correspondence relationships, including the Pitsch one in this case. The local misorientations between individual face- and body-centred cubic crystals along their common interfaces were measured. These can be characterized by the orientation relationships mentioned above as long as a certain amount of tolerance is allowed. Orientation variations within individual kamacite lamellae were also analysed. The crystallographic data support the view that somewhat different mechanisms are involved in the formation of Widmanstaetten structures and of the plessite in meteorites

    Treatment conditions using Y-27632 in the preparation of cell suspension of dissociated human pluripotent stem cells (hiPSCs) were investigated in the context of embryoid body (EB)-like cell aggregates. The effectiveness of a pretreatment with Y-27632 before cell dissociation and that of a Y-27632 treatment during cell dissociation were investigated from the viewpoint of simplicity and robustness. The duration of Y-27632 treatment in the preparation process affected the circularity and agglomeration of dissociated hiPSCs. A single application of pretreatment failed to prevent the onset of blebbing. However, a pretreatment promoted the agglomeration of dissociated hiPSCs when combined with the addition of Y-27632 to cell suspension. Our results indicate that pretreatment enhances the agglomeration potential of dissociated hiPSCs. When cell dissociation was performed in the presence of Y-27632, dissociated hiPSCs possessed the highest circularity and significant agglomerating property. It was shown that treatment with Y-27632 during cell dissociation is a simple and robust method to prepare dissociated hiPSCs for suspension culture to form EB-like cell aggregates.

    2012-01-01

    Background Creatine monohydrate (CrM) has been consistently reported to increase muscle creatine content and improve high-intensity exercise capacity. However, a number of different forms of creatine have been purported to be more efficacious than CrM. The purpose of this study was to determine if a buffered creatine monohydrate (KA) that has been purported to promote greater creatine retention and training adaptations with fewer side effects at lower doses is more efficacious than CrM supplementation in resistance-trained individuals. Methods In a double-blind manner, 36 resistance-trained participants (20.2 ± 2 years, 181 ± 7 cm, 82.1 ± 12 kg, and 14.7 ± 5% body fat) were randomly assigned to supplement their diet with CrM (Creapure® AlzChem AG, Trostberg, Germany) at normal loading (4 x 5 g/d for 7-days) and maintenance (5 g/d for 21-days) doses; KA (Kre-Alkalyn®, All American Pharmaceutical, Billings, MT, USA) at manufacturer’s recommended doses (KA-L, 1.5 g/d for 28-days); or, KA with equivalent loading (4 x 5 g/d for 7-days) and maintenance (5 g/d) doses of CrM (KA-H). Participants were asked to maintain their current training programs and record all workouts. Muscle biopsies from the vastus lateralis, fasting blood samples, body weight, DEXA determined body composition, and Wingate Anaerobic Capacity (WAC) tests were performed at 0, 7, and 28-days while 1RM strength tests were performed at 0 and 28-days. Data were analyzed by a repeated measures multivariate analysis of variance (MANOVA) and are presented as mean ± SD changes from baseline after 7 and 28-days, respectively. Results Muscle free creatine content obtained in a subgroup of 25 participants increased in all groups over time (1.4 ± 20.7 and 11.9 ± 24.0 mmol/kg DW, p = 0.03) after 7 and 28-days, respectively, with no significant differences among groups (KA-L −7.9 ± 22.3, 4.7 ± 27.0; KA-H 1.0 ± 12.8, 9.1 ± 23.2; Cr

    As part of her current lifestyle, a 28-year-old Caucasian woman routinely injures and allows subsequent healing of her skin and other tissues. Her body modifications include a "split tongue" (a tongue split to the base), which does not interfere with speaking and eating. Other modifications include large scarification patterns produced by branding and cutting. This woman has been known to eat parts of her skin that were previously cut out of her body. She also performs "needle play" by allowing medical syringe needles to be lodged temporarily under her skin. The patient had a normal childhood, is currently employed full-time as an office manager, and is psychologically stable. Although one other case of self-induced penoscrotal hypospadias is known, this is the only report of extensive, nonpsychotic, autodestructive behavior. However, this may not be the case in the future as an increasing number of young individuals have become interested in body modifications.

  3. Soul and body: Transcending the dialectical intellectual legacy of the West with an integral biblical view?

    Directory of Open Access Journals (Sweden)

    Full Text Available Greek philosophy informed the Medieval dualistic understanding of ‘body’ and ‘soul’, which continued to influence modern Humanism and Christian views during and after the Middle Ages. These fluctuating conceptions express the directing role of dialectical basic motives. It was mainly the Greek motive of matter and form which directed the thought of Plato and Aristotle, resulting in a dualistic view of the relationship between a so-called material body and rational soul. At the Council of Vienne (1312, the Aristotelian-Thomistic doctrine of the soul as the substantial form of the body was adopted. Within Protestant circles, the‘two-substances’ view caused a distinction between a (temporal material body and an (eternal rational soul (see article 7 of the Swiss Confessio Helvetica Posterior and the Westminster Confession Chapter 4, paragraph 2. Dooyeweerd shows how modern philosophy has received its deepest motivation from the dialectical motive of nature and freedom, which informed the development from Descartes up to Gould and Jaspers. Finally, in the last sections, the main contours of a biblically informed view are articulated with reference to the centrality of the human I-ness, to the theory of enkaptic interlacements and to the problem of supra-temporality. Siel en liggaam: Is dit moontlik om die dialektiese intellektuele erfenis van die Westevanuit ‘n integrale bybelse siening te bowe te kom? Die Griekse filosofie vorm die agtergrond van die Middeleeuse dualistiese verstaan van ‘liggaam’ en ‘siel’ wat op sy beurt die moderne Humanisme en latere Christelike opvattinge beïnvloed het – almal in die greep van dialektiese grondmotiewe. Dit was hoofsaaklik die Griekse basiese vorm-materie-motief wat die dualistiese siening van ’n materie-liggaam en ’n redelike siel tot gevolg gehad het, soos dit in die denke van Plato en Aristoteles beslag gekry het. By die Konsilie van Wenen (1312 is die Aristotelies

    While exposure to fibers and particles has been proposed to be associated with several different lung malignancies including mesothelioma, the mechanism for the carcinogenesis is not fully understood. Along with mineralogical observation, we have analyzed forty-four major and trace elements in extracted asbestos bodies (fibers and proteins attached to them) with coexisting fiber-free ferruginous protein bodies from extirpative lungs of individuals with malignant mesothelioma. These observations together with patients' characteristics suggest that inhaled iron-rich asbestos fibers and dust particles, and excess iron deposited by continuous cigarette smoking would induce ferruginous protein body formation resulting in ferritin aggregates in lung tissue. Chemical analysis of ferruginous protein bodies extracted from lung tissues reveals anomalously high concentrations of radioactive radium, reaching millions of times higher concentration than that of seawater. Continuous and prolonged internal exposure to hotspot ionizing radiation from radium and its daughter nuclides could cause strong and frequent DNA damage in lung tissue, initiate different types of tumour cells, including malignant mesothelioma cells, and may cause cancers.

    Appearance-related disturbances are common among HIV-infected MSM; however, to date, there have been limited options in the valid assessment of this construct. The aim of the current study was to assess the structural, internal, and convergent validity of the assessment of body change distress questionnaire (ABCD) and its short version. Exploratory and confirmatory factor analyses indicated that both versions fit the data well. Four subfactors were revealed measuring the following body disturbance constructs: (1) negative affect about appearance, (2) HIV health-related outcomes and stigma, (3) eating and exercise confusion, and (4) ART non-adherence. The subfactors and total scores revealed bivariate associations with salient health outcomes, including depressive symptoms, HIV sexual transmission risk behaviors, and ART non-adherence. The ABCD and its short form, offer valid means to assess varied aspects of body image disturbance among HIV-infected MSM, and require modest participant burden.

    Genetic rearrangements are a hallmark of several forms of leukemia and can lead to oncogenic fusion proteins. One example of an affected chromosomal region is the gene coding for Nup214, a nucleoporin that localizes to the cytoplasmic side of the nuclear pore complex (NPC). We investigated two such fusion proteins, SET-Nup214 and SQSTM1 (sequestosome)-Nup214, both containing C-terminal portions of Nup214. SET-Nup214 nuclear bodies containing the nuclear export receptor CRM1 were observed in the leukemia cell lines LOUCY and MEGAL. Overexpression of SET-Nup214 in HeLa cells leads to the formation of similar nuclear bodies that recruit CRM1, export cargo proteins, and certain nucleoporins and concomitantly affect nuclear protein and poly(A) + RNA export. SQSTM1-Nup214, although mostly cytoplasmic, also forms nuclear bodies and inhibits nuclear protein but not poly(A) + RNA export. The interaction of the fusion proteins with CRM1 is RanGTP-dependent, as shown in co-immunoprecipitation experiments and binding assays. Further analysis revealed that the Nup214 parts mediate the inhibition of nuclear export, whereas the SET or SQSTM1 part determines the localization of the fusion protein and therefore the extent of the effect. SET-Nup214 nuclear bodies are highly mobile structures, which are in equilibrium with the nucleoplasm in interphase and disassemble during mitosis or upon treatment of cells with the CRM1-inhibitor leptomycin B. Strikingly, we found that nucleoporins can be released from nuclear bodies and reintegrated into existing NPC. Our results point to nuclear bodies as a means of preventing the formation of potentially insoluble and harmful protein aggregates that also may serve as storage compartments for nuclear transport factors. © 2016 by The American Society for Biochemistry and Molecular Biology, Inc.

    2017-02-01

    Full Text Available The problem of supersonic streamlining of an aerodynamic (AD body, “a plate blunted by a cylinder”, by a flow with the freestream Mach number M = 4 containing an external energy source has been studied, taking into account physicochemical transformations. The results of the effect of the ratio of specific heats γ changing in the range from 1.1 to 1.4 on the dynamics of triple-shock configurations and vortex-contact structures are presented for the interaction of an energy source with the bow shock wave. The energy source is modeled via the heated rarefied layer (filament. The angles in the triple-shock configurations, the stagnation pressure, together with the frontal drag force, have been studied dependent on the specific heats ratio γ, the characteristics of the energy source, and also on the angle of the incident shock. Vortex-contact structures have been researched for the Mach numbers 7, 8, 9, as well as the generation of the Richtmyer-Meshkov instability accompanying the formation of a triple-shock configuration. The results show a strong influence of the specific heats ratio of the gas medium and the parameters of the energy source on the triple-shock configuration and aerodynamic characteristics of the body. This conclusion can be useful for aerospace applications in the area of the design of nozzles, intakes, and high speed flying vehicles. Additionally, the results show the possibility of flow control in the atmospheres of other planets using external energy deposition.

  11. Empirical Determinations of the Extent and Form of Ice-Proximal Water Bodies in the Canadian Arctic Archipelago During the Last Deglaciation

    Digital reconstructions of late Quaternary landscapes deformed by differential glacio-isostatic rebound can be made using a geographic information system (GIS) method that subtracts interpolated isobase values from modern elevations and bathymetry. A principal utility of the GIS method for reconstructing late Quaternary landscapes is in the relative ease and rapidity with which high-resolution, quantitative, and georeferenced databases of paleo-topography can be generated. Databases of paleo-topography can be used to approximately determine the positions of paleo-shorelines over large areas, and to estimate the extent and volume of ancient ice-proximal water bodies. By providing quantitative information on the dimensions of ice-proximal water bodies, such databases may in the future help to constrain models of crustal loading and isostasy in the arctic. Using modern elevations and bathymetry (derived from the GLOBE and ETOPO5 databases, respectively) and isobase data compiled by Dyke et al. (1991), the GIS method has been used to reconstruct the paleo-topography of the central region of the Canadian Arctic Archipelago at 9300 14C yr B.P. (latitudes 68 to 76 N, and longitudes 80 to 112 W). The new database of paleo-topography delineates the approximate shoreline and subaerial extent of the region's islands at 9300 14C yr B.P., and is a topographic and bathymetric model of the region at that time. The database demonstrates that the surface area of terrain above sea level in the study region (about 258,000 km2) was about 50% less than today, with reductions in the surface area of individual land units ranging between about 18% (e.g., Somerset Island, and Brodeur Peninsula on Baffin Island) and 100% (e.g., King William Island, which at 9300 14C yr B.P. was covered by the Laurentide Ice Sheet). Water volume within the study region (about 150,000 km3) was about 240% greater than today, and correspondingly the cross sectional areas of many channels in the region were more

    In this 14-d cage study, the effects of feed form (mash and crumble) and 6 coarse ground corn ( CC: ) inclusions [0, 10, 20, 30, 40, and 50% CC that replaced fine corn ( FC: )] on broiler live performance, BW uniformity, gizzard weight, excreta nitrogen, and particle size preference were investigated. The geometric mean diameter by mass ( DGW: ) of mash diets increased from 422 μm to 431, 471, 509, 542, and 640 μm, respectively, as the percentage of CC increased. Feed intake and BW were decreased by CC and mash at 7 d. Interactions between feed form and CC were observed for feed conversion ratio ( FCR: ) at 7 d of age (P nitrogen was increased (P < 0.01) by crumble diets. These data demonstrated that pelleting and crumbling reduced the impact of CC, produced a more consistent feed intake, and reduced selective feeding, and that CC stimulated gizzard weight in a linear manner in mash diets. © 2015 Poultry Science Association Inc.

    Using a methylcellulose-supported bone marrow culture system, the dose-response relationships of suspended granulocyte-monocyte colonies (CFU-C) and adherent fibroblastic colonies (PFU-C) were investigated in 2- to 3-month-old beagles exposed to acute whole-body γ irradiation. Groups of weanling beagles were exposed at a rate of 140 R/hr delivered from a 60 Co γ source achieving total exposures ranging from 0 to 586 R. Twenty-four hours following irradiation, bone marrow was collected, plated into methylcellulose, and after 1 week of incubation both colony types were quantitated. In addition, bone marrow cellularity determinations were made for a variety of bones using an 59 Fe-labeling technique. The results show a D 37 for the linear part of the slope of 70 R for CFU-C. Although within the limits of the experiment a D 37 could not be established for the fibroblastic populations, the results indicate a substantial degree of radioresistance for these elements supporting our previous studies on PFU-C, performed on mice, which suggested a D 37 of approximately 400 R for the progenitors of these fibroblastic elements

  14. A study of the cytoplasmic expression of a form of human prolactin and of its solubilization and renaturation from bacterial inclusion bodies

    Affonso, Regina

    2000-01-01

    Different vector elements, that can determine a high expression level of a form of human prolactin (taghPrl) in bacterial cytoplasm, were studied. Expression conditions were first optimized for a reference vector, which was used to transform different strains of E. coli: HB2151, RRI and RB791. The highest expression level (113 ±16 μg/mL.A 600 ) was obtained in HB2151, after activation with only 0.1 mM IPTG. At this point the influence of the transcription terminator (g32 from bacteriophage T4), of the translation enhancer (g10 from bacteriophage T7), of the promoter (λP L or tac) and of the antibiotic resistance gene (amp r or kan r ) were studied. The first three elements did not show any significant influence, at least in our systems. On the contrary, the analysis of the influence of amp r and kan r genes showed, unexpectedly, that the presence of the last one provides an approximately 5-fold higher expression for taghPrl in E. coli cytoplasm. Finally, an appropriate extraction, solubilization, renaturation and purification process, able to provide a monomeric form of taghPrl, was studied. A method utilizing urea and mercaptoethanol as solubilizing agents and a dialysis as a renaturation procedure, provided with some modifications, one of the highest yields ever reported in the literature: 35.4 ± 4.5% of total recovery. Moreover, the biological activity of the taghPrl obtained, when tested in the Nb2 cell proliferation assay, was of the same order of that shown by the International Standard of human prolactin of pituitary origin. These data show that the cytoplasmic expression system here described, which can provide an expression efficiency 50-100 - fold higher than the periplasmic expression, can represent a valid alternative for the production of this and of other hormones of pharmaceutical interest and grade.

    Full Text Available Human Bone Morphogenetic Protein-2 (hBMP2 is an osteoinductive agent physiologically involved in bone remodelling processes. A commercialized recombinant hBMP2 produced in mammalian cell lines is available in different clinical applications where bone regeneration is needed, but widespread use has been hindered due to an unfavorable cost/effective ratio. Protein bodies are very large insoluble protein polymers that originate within the endoplasmic reticulum by prolamine accumulation during the cereal seed development. The N-terminal domain of the maize prolamin 27 kD -zein is able to promote protein body biogenesis when fused to other proteins. To produce high yield of recombinant hBMP2 active domain (ad in stably transformed tobacco plants we have fused it to the γ-zein domain. We show that this zein-hBMP2ad fusion is retained in the endoplasmic reticulum without forming insoluble protein bodies. The accumulation levels are above 1% of total soluble leaf proteins, indicating that it could be a rapid and suitable strategy to produce hBMP2ad at affordable costs.

    Systematic review about randomised trials comparing different training strategies to improve gait in people with spinal cord injuries (SCI). The aim of this systematic review was to compare the effectiveness of body-weight-supported treadmill training (BWSTT) and robotic-assisted gait training with overground gait training and other forms of physiotherapy in people with traumatic SCI. Systematic review conducted by researchers from Germany and Australia. An extensive search was conducted for randomised controlled trials involving people with traumatic SCI that compared either BWSTT or robotic-assisted gait training with overground gait training and other forms of physiotherapy. The two outcomes of interest were walking speed (m s -1 ) and walking distance (m). BWSTT and robotic-assisted gait training were analysed separately, and data were pooled across trials to derive mean between-group differences using a random-effects model. Thirteen randomised controlled trials involving 586 people were identified. Ten trials involving 462 participants compared BWSTT to overground gait training and other forms of physiotherapy, but only nine trials provided useable data. The pooled mean (95% confidence interval (CI)) between-group differences for walking speed and walking distance were -0.03 m s -1 (-0.10 to 0.04) and -7 m (-45 to 31), respectively, favouring overground gait training. Five trials involving 344 participants compared robotic-assisted gait training to overground gait training and other forms of physiotherapy but only three provided useable data. The pooled mean (95% CI) between-group differences for walking speed and walking distance were -0.04 m s -1 (95% CI -0.21 to 0.13) and -6 m (95% CI -86 to 74), respectively, favouring overground gait training. BWSTT and robotic-assisted gait training do not increase walking speed more than overground gait training and other forms of physiotherapy do, but their effects on walking distance are not clear.

    Although inherently linked, body form and body action may be represented in separate neural substrates. Using repetitive transcranial magnetic stimulation in healthy individuals, we show that interference with the extrastriate body area impairs the discrimination of bodily forms, and interference with the ventral premotor cortex impairs the discrimination of bodily actions. This double dissociation suggests that whereas extrastriate body area mainly processes actors' body identity, premotor cortex is crucial for visual discriminations of actions.

  12. The Athletic Body.

    Science.gov (United States)

    Edgar, Andrew

    2016-09-10

    This paper seeks to explore the attraction and the beauty of the contemporary athletic body. It will be suggested that a body shaped through muscular bulk and definition has come to be seen as aesthetically normative. This body differs from the body of athletes from the early and mid-twentieth century. It will be argued that the contemporary body is not merely the result of advances in sports science, but rather that it is expressive of certain meanings and values. The visual similarity of the contemporary athletic body and that of the comic book superhero suggests that both bodies carry a similar potential for narrative story-telling, and that their attraction is bound up with this narrative potential. The superhero and athlete live meaningful lives, pursuing clear and morally unambiguous goals. The aesthetic attraction of the body lies in its capacity to facilitate the articulation of a story of a meaningful life, and to do so in the face of the growing anomie and thus meaninglessness of life as experienced in contemporary society. Athleticism offers an illusion of meaning, serving to reproduce dominant justificatory narratives and social stereotypes. Yet, as an illusion of meaning, it may be challenged and negotiated, not least with respect to its bias towards a certain form of the male body. The female athletic body disrupts the illusion, opening up new existential possibilities, new ways of living and being, and thus new, and potentially disruptive, narratives.

    Full Text Available In the Fall of 2013 we team-taught a disability studies course for a small group of first-year students. The course, Minding the Body, integrated scholarship from disability studies, feminist/queer studies, psychology, and Russian Studies. Originally envisioned and taught independently in the Fall of 2012 by Joan Ostrove and focused entirely on the U.S., Anastasia Kayiatos's arrival in the Department of German and Russian Studies at Macalester College afforded us an opportunity for collaboration and co-instruction that we found invigorating, compelling, and transformative. Grounded from the outset in disability studies, the course asked students to interrogate such questions as: What is a "normal" body? A "beautiful" body? Why do we feel the way we do about our bodies? How are bodies objectified, exploited, and regulated? How and why do we discriminate against people with non-normative bodies? How do people represent the experience of having a disabled body? How can we think critically about the various ways in which people change, regulate, and enhance their bodies? How do sexism, racism, classism, colonialism, homophobia, transphobia and other forms of oppression influence how different bodies are viewed, treated, educated, and experienced? The integration of Russian Studies importantly allowed us to ask how these questions and ideas change when we travel across time and geographical space. In our paper we will reflect on our experience of co-authoring the syllabus (we will include both the solo-taught and co-taught versions of the syllabus in an appendix; outline some of our techniques for team-teaching; and analyze an exemplary assignment and class meeting. We will conclude with a final word about the unique forms of teaching and learning that happened in our class as a consequence of its collaborative and interdisciplinary approach, which opened up new perspectives in disability studies not only for our students but also for us.

    Perhaps the greatest mystery surrounding dinosaurs concerns whether they were endotherms, ectotherms, or some unique intermediate form. Here we present a model that yields estimates of dinosaur body temperature based on ontogenetic growth trajectories obtained from fossil bones. The model predicts that dinosaur body temperatures increased with body mass from approximately 25 °C at 12 kg to approximately 41 °C at 13,000 kg. The model also successfully predicts observed increases in body temperature with body mass for extant crocodiles. These results provide direct evidence that dinosaurs were reptiles that exhibited inertial homeothermy. PMID:16817695

    2002-07-01

    For millennia people have altered the appearance of their bodies with cosmetics, jewellery, tattoos, piercings, and other surgical procedures. It would appear that they wish to conform to a perceived 'ideal body', although the actual appearance of such a body is subject to temporal, cultural and geographical change. In contemporary society the media are largely responsible for providing the yardsticks against which individual body shape is measured. Today the desired form is generally young, slim, tanned and blemish-free. Sadly, dissatisfaction with body image can be the source of great unhappiness and may even lead to suicide. Interested scholars have debated the meaning of beauty for centuries but it seems that every human society has its own standards. At the simplest it would appear that youth and symmetry are the most highly prized ingredients. There is no doubt that those who fit the conventional standards of attractiveness are treated better by society. Individuals have an inalienable right to their own body appearance, and to alter it as they see fit, however such modifications may not always be in their own best interests. Practitioners of cosmetic procedures must be alert to clients with histories of weight fluctuation, unrealistic body image, or low self-esteem. Psychological disorders may present with dysmorphophobic symptoms. Doctors providing cosmetic services need to be adept at diagnosing psychological illness.

    This study explores the body disposal patterns in a sample of 54 Korean homicides that occurred between 2006 and 2012. Based on information collected by the police during their investigation, factors that could influence body disposal patterns were examined, such as homicide classification, intention, whether an accomplice was present, and offender mental disorder. Bivariate analyses showed that the majority of the victims who were disposed of were acquaintances of the offenders. Moreover, several offenders were more likely to dispose of the dead body "within hours" of killing the victim. Dead bodies were usually recovered in agricultural areas, forest/wooded areas, as well as residential areas. It was also noteworthy that, in 47 cases, the offender had knowledge of the geographic area where the body was dumped. In cases of "expressive" homicide, victims were more likely to be disposed of somewhere far away (e.g., over 40 km) from the crime scene, whereas "instrumental" homicide victims appeared to be disposed of somewhere closer (e.g., within 30 km) to the crime scene. Results are discussed in light of their practical implications for homicide investigations.

    2001-01-01

    The high-tech art of digital signal processing (DSP) was pioneered at NASA's Jet Propulsion Laboratory (JPL) in the mid-1960s for use in the Apollo Lunar Landing Program. Designed to computer enhance pictures of the Moon, this technology became the basis for the Landsat Earth resources satellites and subsequently has been incorporated into a broad range of Earthbound medical and diagnostic tools. DSP is employed in advanced body imaging techniques including Computer-Aided Tomography, also known as CT and CATScan, and Magnetic Resonance Imaging (MRI). CT images are collected by irradiating a thin slice of the body with a fan-shaped x-ray beam from a number of directions around the body's perimeter. A tomographic (slice-like) picture is reconstructed from these multiple views by a computer. MRI employs a magnetic field and radio waves, rather than x-rays, to create images.

  8. Body Weight and Body Image

    2004-08-01

    Full Text Available Abstract Health Issue Body weight is of physical and psychological importance to Canadian women; it is associated with health status, physical activity, body image, and self-esteem. Although the problems associated with overweight and obesity are indeed serious, there are also problems connected to being underweight. Weight prejudice and the dieting industry intensify body image concerns for Canadian women and can have a major negative impact on self-esteem. Key Findings Women have lower BMIs than men, a lower incidence of being overweight and a higher incidence of being underweight. However, women across all weight categories are more dissatisfied with their bodies. Sixty percent of women are inactive, and women with a BMI of 27 or higher are more likely to be inactive than women with lower BMIs. The data show that women are aware of the health benefits of exercise, but there is a gap between knowledge and practice. When asked about barriers to health improvement, 39.7% of women cited lack of time and 39.2% lack of willpower. Data Gaps and Recommendations Weight prejudice must be made unacceptable and positive body image should be encouraged and diversity valued. Health policies should encourage healthy eating and healthy activity. Health curricula for young students should include information about healthy eating, active lifestyle, and self-esteem. Physical activities that mothers can participate in with their families should be encouraged. Research should be funded to elucidate the most effective methods of getting women to become and remain physically active without focusing on appearance.

The one-woman show Impossible Body was first performed for a reading series sponsored by "Onstage" at the University of Colorado, Boulder, in February 1997. A revised version was developed and staged at the University of Puget Sound in Tacoma, Washington in April 1997. The current script, from which these excerpts are taken, was first presented at the Queer Studies Conference in Boulder, Colorado.

    Pre-firing mullite microstructures developed by a new thermal consolidation method using globular proteins as foaming and consolidator/binders were analyzed. Commercial available powders of mullite (Baikowski) and bovine serum albumin (BSA, Aldricht) were employed. Stable aqueous suspensions (40 vol.%) of mullite- BSA (10 vol.%) were foamed (2300 rpm, 10 min) at: I) room temperature; II) 68 deg C, temperature slightly lower to the gelling 'onset' TG 0 , and III) 68 deg C with the addition of 2 wt.% of methylcellulose. Green disks were prepared by pouring of foamed suspensions into pre-heated metal molds (70 deg C), thermal gelling (80 °C, 3h) and drying (50 °C, 12h). Previously, the developed foams were characterized and their rheological properties were determined as a function of temperature (TG 0 ). The characterization of the pre-firing microstructures were carried out by measurements of porosity (>80%) and microstructural analysis in fracture surface by SEM. (author)

    Modular forms and Jacobi forms play a central role in many areas of mathematics. Over the last 10-15 years, this theory has been extended to certain non-holomorphic functions, the so-called "harmonic Maass forms". The first glimpses of this theory appeared in Ramanujan's enigmatic last letter to G. H. Hardy written from his deathbed. Ramanujan discovered functions he called "mock theta functions" which over eighty years later were recognized as pieces of harmonic Maass forms. This book contains the essential features of the theory of harmonic Maass forms and mock modular forms, together with a wide variety of applications to algebraic number theory, combinatorics, elliptic curves, mathematical physics, quantum modular forms, and representation theory.

    1977-09-01

    Faddeev equations for the three-body problem are reconsidered using separable two-body interactions. The separable potentials reduce the Faddeev equations to coupled integral equations in one continuous variable. Numerical calculations for the resulting integral equations are carried out using separable two-body interactions which include both attraction and repulsion potentials. Each of the separable attraction and repulsion potentials used is taken as a spin-dependent central force together with tensor forces. The potential functions of the different parts of the two body interactions are taken to be of the Yamaguchi, Gaussian, Tabakin, Mongan and Reid forms. Each of the nuclei 6 Li, 9 Be and 12 C is taken to be composed of three particles according to the cluster structure description of nuclei. The binding energies of the nuclei 6 Li, 9 Be and 12 C are calculated as a three-body problem and in the framework of the Faddeev formalism

    The human body is the object upon which medicine is acting, but also lived reality, image, symbol, representation and the object of elaboration and theory. All these elements which constitute the body influence the way medicine is treating it. In this series of three articles, we address the human body from various perspectives: medical (1), phenomenological (2), psychosomatic and socio-anthropological (3). This first article discusses four distinct types of representation of the body within medicine, each related to a specific epistemology and shaping a distinct kind of clinical legitimacy: the body-object of anatomy, the body-machine of physiology, the cybernetic body of biology, the statistical body of epidemiology.

  20. Modular Forms and Weierstrass Mock Modular Forms

    Directory of Open Access Journals (Sweden)

    Amanda Clemm

    2016-02-01

    Full Text Available Alfes, Griffin, Ono, and Rolen have shown that the harmonic Maass forms arising from Weierstrass ζ-functions associated to modular elliptic curves “encode” the vanishing and nonvanishing for central values and derivatives of twisted Hasse-Weil L-functions for elliptic curves. Previously, Martin and Ono proved that there are exactly five weight 2 newforms with complex multiplication that are eta-quotients. In this paper, we construct a canonical harmonic Maass form for these five curves with complex multiplication. The holomorphic part of this harmonic Maass form arises from the Weierstrass ζ-function and is referred to as the Weierstrass mock modular form. We prove that the Weierstrass mock modular form for these five curves is itself an eta-quotient or a twist of one. Using this construction, we also obtain p-adic formulas for the corresponding weight 2 newform using Atkin’s U-operator.

    Science.gov (United States)

    Meir, Irit; Padden, Carol A; Aronoff, Mark; Sandler, Wendy

    2007-11-01

    The notion of subject in human language has a privileged status relative to other arguments. This special status is manifested in the behavior of subjects at the morphological, syntactic, semantic and discourse levels. Here we bring evidence that subjects have privileged status at the lexical level as well, by analyzing lexicalization patterns of verbs in three different sign languages. Our analysis shows that the sublexical structure of iconic signs denoting state of affairs in these languages manifests an inherent pattern of form-meaning correspondence: the signer's body consistently represents one argument of the verb, the subject. The hands, moving in relation to the body, represent all other components of the event - including all other arguments. This analysis shows that sign languages provide novel evidence in support of the centrality of the notion of subject in human language. It also solves a typological puzzle about the apparent primacy of object in sign language verb agreement, a primacy not usually found in spoken languages, in which subject agreement ranks higher. Our analysis suggests that the subject argument is represented by the body and is part of the lexical structure of the verb. Because it is always inherently represented in the structure of the sign, the subject is more basic than the object, and tolerates the omission of agreement morphology.

    Few-body hadronic observables play an essential role in a wide number of processes relevant for both particle and nuclear physics. In order for Lattice QCD to offer insight into the interpretation of few-body states, a theoretical infrastructure must be developed to map Euclidean-time correlation functions to the desired Minkowski-time few-body observables. In this talk, I will first review the formal challenges associated with the studies of such systems via Lattice QCD, as first introduced by Maiani and Testa, and then review methodology to circumvent said limitations. The first main example of the latter is the formalism of Luscher to analyze elastic scattering and a second is the method of Lellouch & Luscher to analyze weak decays. I will then proceed to discus recent theoretical generalizations of these frameworks that allow for the determination of scattering amplitudes, resonances, transition and elastic form factors. Finally, I will outline outstanding problems, including those that are now beginning to be addressed.

    2013-01-01

    This book provides essential information on metal forming, utilizing a practical distinction between bulk and sheet metal forming. In the field of bulk forming, it examines processes of cold, warm and hot bulk forming, as well as rolling and a new addition, the process of thixoforming. As for the field of sheet metal working, on the one hand it deals with sheet metal forming processes (deep drawing, flange forming, stretch drawing, metal spinning and bending). In terms of special processes, the chapters on internal high-pressure forming and high rate forming have been revised and refined. On the other, the book elucidates and presents the state of the art in sheet metal separation processes (shearing and fineblanking). Furthermore, joining by forming has been added to the new edition as a new chapter describing mechanical methods for joining sheet metals. The new chapter “Basic Principles” addresses both sheet metal and bulk forming, in addition to metal physics, plastomechanics and computational basics; ...

    2017-04-01

    When the Earth was formed, it was in a state of burning heat. As time went by, temperature on the planet's surface was falling due to radiation and heat transfer, and various components (crusts) began taking solid form at the Earth's poles. The formation of crusts took place at the Earth's poles, because the stirring of burning and fluid masses on the surface of the Earth was significantly slighter there than it was on the equator. Due to centrifugal force and Coriolis Effect, these solid masses headed towards the equator; those originating from the North Pole followed a south-western course, while those originating from the South Pole followed a north-western course and there they rotated from west to east at a lower speed than the underlying burning and liquid earth, because of their lower initial linear velocity, their solid state and inertia. Because inertia is proportional to mass, the initially larger solid body swept all new solid ones, incorporating them to its western side. The density of the new solid masses was higher, because the components on the surface would freeze and solidify first, before the underlying thicker components. As a result, the western side of the initial islet of solid rocks submerged, while the east side elevated. . As a result of the above, this initial islet began to spin in reverse, and after taking on the shape of a sphere, it formed the "heart" of the Moon. The Moon-sphere, rolling on the equator, would sink the solid rocks that continued to descend from the Earth's poles. The sinking rocks partially melted because of higher temperatures in the greater depths that the Moon descended to, while part of the rocks' mass bonded with the Moon and also served as a heat-insulating material, preventing the descended side of the sphere from melting. Combined with the Earth's liquid mass that covered its emerging eastern surface, new sphere-shaped shells were created, with increased density and very powerful structural cohesion. During the

    2014-10-01

    Full Text Available Eating disorders should be understood in a multidimensional perspective, emphasizing a biopsicossocial context. In these pathologies it`s the body, in the first instance, that reveals the disease, being in this way the target of the conflict, revealing a disturbed body experience and as a consequence a weak conception of their personal body image. The body image is conceptualised as a subjective image that the individuals form in their own mind, about their body, in relation with differ- ent contexts of life. The intent of the studies is to comprehend the level of body image disturbance, which have concluded that in the majority of the cases, significant changes on perceptive capacity of the patients do not exist. In this way it`s important to study in a more effective and qualitative way the affective and personal factors. The authors pretend with this bibliographic revision, make a research of body image assessment to the Eating Disorders (Anorexia Nervosa and Bulimia Nervosa, and to reflect which are the best ones to adapt for Portuguese reality.

  11. Body Image and Body Contouring Procedures.

    Science.gov (United States)

    Sarwer, David B; Polonsky, Heather M

    2016-10-01

    Dissatisfaction with physical appearance and body image is a common psychological phenomena in Western society. Body image dissatisfaction is frequently reported by those who have excess body weight, but also is seen in those of normal body weight. For both groups of individuals, this dissatisfaction impacts self-esteem and quality of life. Furthermore, it is believed to be the motivational catalyst to a range of appearance-enhancing behaviors, including weight loss efforts and physical activity. Body image dissatisfaction is also believed to play a role in the decision to seek the wide range of body contouring procedures offered by aesthetic physicians. Individuals who seek these procedures typically report increased body image dissatisfaction, focus on the feature they wish to alter with treatment, and often experience improvement in body image following treatment. At the same time, extreme body image dissatisfaction is a symptom of a number of recognized psychiatric disorders. These include anorexia nervosa, bulimia nervosa, and body dysmorphic disorder (BDD), all of which can contraindicate aesthetic treatment. This special topic review paper provides an overview of the relationship between body image dissatisfaction and aesthetic procedures designed to improve body contouring. The review specifically focuses on the relationship of body image and body weight, as well as the presentation of body image psychopathology that would contraindicate aesthetic surgery. The overall goal of the paper is to highlight the clinical implications of the existing research and provide suggestions for future research on the psychological aspects of body contouring procedures. © 2016 The American Society for Aesthetic Plastic Surgery, Inc.

  13. Functional MRI analysis of body and body part representations in the extrastriate and fusiform body areas.

    Science.gov (United States)

    Taylor, John C; Wiggett, Alison J; Downing, Paul E

    2007-09-01

    This study examined the contributions of two previously identified brain regions-the extrastriate and fusiform body areas (EBA and FBA)-to the visual representation of the human form. Specifically we measured in these two areas the magnitude of fMRI response as a function of the amount of the human figure that is visible in the image, in the range from a single finger to the entire body. A second experiment determined the selectivity of these regions for body and body part stimuli relative to closely matched control images. We found a gradual increase in the selectivity of the EBA as a function of the amount of body shown. In contrast, the FBA shows a steplike function, with no significant selectivity for individual fingers or hands. In a third experiment we demonstrate that the response pattern seen in EBA does not extend to adjacent motion-selective human midtemporal area. We propose an interpretation of these results by analogy to nearby face-selective regions occipital face area (OFA) and fusiform face area (FFA). Specifically, we hypothesize that the EBA analyzes bodies at the level of parts (as has been proposed for faces in the OFA), whereas FBA (by analogy to FFA) may have a role in processing the configuration of body parts into wholes.

    Science.gov (United States)

    Chang, Shiow-Ru; Chao, Yu-Mei Yu

    2007-06-01

    "Body" is a basic concept of both the natural and human sciences. This extensive review of the literature explores the various philosophical approaches to the body, including empiricism, idealism, existentialism and phenomenology, as well as the relationship between body and mind. Embodiment and body image are the two main concepts of body addressed in this article. Merleau-Ponty's perspective on embodiment, an important new area of theory development, emphasizes that embodiment research must focus on life experiences, such as the study of body image. Using Schilder's framework of psychosocialology, this article provides a comprehensive understanding of the concept of body image and women's perspectives on the "body" in both Western culture and Eastern cultures. Body size and shape significantly influence the self-image of women. Body image is something that develops and changes throughout one's life span and is continually being constructed, destructed, and reconstructed. Personal body image has important psychological effects on the individual, especially women. This integrative review can make a significant contribution to knowledge in this area and, consequently, to related practice and research.

    Directory of Open Access Journals (Sweden)

    P. Naudé

    2012-02-01

    Full Text Available This paper, originally read as the fourth Willie Jonker commemoration lecture (October 2009, explores how the central tenets of Jonker’s theology have been fundamentally shaped by John Calvin. It is argued that Jonker’s very understanding of Reformed theology is derived from Calvin. Furthermore, on three issues, Calvin plays an important role: Jonker’s insistence on the visible unity of the church, the importance of social ethics, and the church as the people of God superseding the ethnic notion of a volkskerk. The paper concludes with a list of contemporary theological and ethical issues that may be addressed from the Calvin-Jonker line of thinking.

    Three-body problems are basic for the quantum mechanics of molecular, atomic, or nuclear systems. We demonstrate that their variational solution for rotational states can be greatly simplified. A special choice of coordinates (hyperspherical) and of the kinematics (body-fixed coordinate frame) allows one to choose basis functions in a form that makes the angular coupling trivial. (author)

    Micro Metal Forming, i. e. forming of parts and features with dimensions below 1 mm, is a young area of research in the wide field of metal forming technologies, expanding the limits for applying metal forming towards micro technology. The essential challenges arise from the reduced geometrical size and the increased lot size. In order to enable potential users to apply micro metal forming in production, information about the following topics are given: tribological behavior: friction between tool and work piece as well as tool wear mechanical behavior: strength and formability of the work piece material, durability of the work pieces size effects: basic description of effects occurring due to the fact, that the quantitative relation between different features changes with decreasing size process windows and limits for forming processes tool making methods numerical modeling of processes and process chains quality assurance and metrology All topics are discussed with respect to the questions relevant to micro...

  20. Body size perception and body satisfaction in restrained and unrestrained eaters.

    Lautenbacher, S; Thomas, A; Roscher, S; Strian, F; Pirke, K M; Krieg, J C

    1992-05-01

    In 21 restrained and 20 unrestrained eaters body size perception was measured using the video distortion technique (VDT), the image marking procedure (IMP) and the kinesthetic size estimating apparatus (KSEA). Body satisfaction was assessed by questionnaires (Body Shape Questionnaire, Dieting scale of the Eating Attitudes Test). Restrained eaters showed no systematic over- or underestimation of the body size but less perceptual accuracy (in VDT and KSEA). Furthermore, they were clearly more dissatisfied with their bodies than unrestrained eaters. Both findings were unrelated to each other. In both groups depressive mood or thoughts seemed to be associated with body dissatisfaction but not with body size misperception. Objective body measures (body mass index, body fat content) were not related to either body size perception or body satisfaction. The findings suggest that a perceptual uncertainty in regard to body size (either for visual or for somatosensory aspects) has already developed in restrained eaters, which may constitute a predisposition for more overt forms of body size misperception as found in eating disorder patients.

  3. Innocent Body-Shadow Mimics Physical Body

    Directory of Open Access Journals (Sweden)

    Kenri Kodaka

    2017-04-01

    Full Text Available The paradigm of the rubber hand illusion was applied to a shadow to determine whether the body-shadow is a good candidate for the alternative belonging to our body. Three kinds of shadows, a physical hand, a hand-shaped cloth, and a rectangle cloth, were tested for this purpose. The questionnaire results showed that both anatomical similarity and visuo-proprioception correlation were effective in enhancing illusory ownership of the shadow. According to the proprioceptive drift measurement, whether the shadow purely originated from the physical body was a critical factor in yielding the significantly positive drift. Thus, results demonstrated that the shadow can distort illusory ownership with the rubber hand illusion paradigm, but the proprioception was clearly distorted only when the body-shadow was purely applied. This implies the presence of special cognitive processing to discriminate the self-body shadow from the others.

    2012-05-01

    Disturbance of body perception is a central aspect of anorexia nervosa (AN) and several neuroimaging studies have documented structural and functional alterations of occipito-temporal cortices involved in visual body processing. However, it is unclear whether these perceptual deficits involve more basic aspects of others' body perception. A consecutive sample of 15 adolescent patients with AN were compared with a group of 15 age- and gender-matched controls in delayed matching to sample tasks requiring the visual discrimination of the form or of the action of others' body. Patients showed better visual discrimination performance than controls in detail-based processing of body forms but not of body actions, which positively correlated with their increased tendency to convert a signal of punishment into a signal of reinforcement (higher persistence scores). The paradoxical advantage of patients with AN in detail-based body processing may be associated to their tendency to routinely explore body parts as a consequence of their obsessive worries about body appearance.

  5. INSAR OF AQUATIC BODIES

    Directory of Open Access Journals (Sweden)

    P. Tarikhi

    2012-07-01

    Full Text Available Radar remote sensing is a new earth observation technology with promising results and future. InSAR is a sophisticated radar remote sensing technique for combining synthetic aperture radar (SAR single look complex images to form interferogram and utilizing its phase contribution to land topography, surface movement and target velocity. In recent years considerable applications of Interferometric SAR technique have been developed. It is an established technique for precise assessment of land surface movements, and generating high quality digital elevation models (DEM from space-borne and airborne data. InSAR is able to produce DEMs with the precision of a couple of ten meters whereas its movement map results have sub-centimeter precision. The technique has many applications in the context of earth sciences such as topographic mapping, environmental modelling, rainfall-runoff studies, landslide hazard zonation, and seismic source modelling. Nevertheless new developments are taking place in the application of InSAR for aquatic bodies. We have observed that using SAR Interferometry technique for aquatic bodies with the maximum temporal baseline of 16 seconds for image pairs shows considerable results enabling us to determine the direction of sea surface motion in a large area, estimate the sea surface fluctuations in the direction of sensor line-of-the-sight, detect wave pattern and the sea surface disturbance and whether the water motion is bulk and smooth or otherwise. This paper presents our experience and achievements on this new topic through discussing the facts and conditions for the use of InSAR technique. The method has been examined for Haiti, Dominican Republic, Western Chile and Western Turkey coast areas and inland lakes however ground truth data is needed for final verification. This technique scheduled to be applied in some other sites for which the proper data is available.

    The purpose of the Symposium was to discuss interdisciplinal science aspects of form. 'Form' depends on the material and the changes. But, it is the form that appears evident at once and endures. Form is absorbed from every field as media of information. One part of the work covers the description of non-periodic phenomena, morphogenesis or evolution. Irreducible stubborn facts as diseases or social problems, or whatever else that could not be analyzed are integrally challenged to be systematized by computer simulation. The other part covers the finding of laws for determining how systems behave. Attention should be paid to pattern recognition, image processing and pattern formation. The Symposium proceeded with no parallel sessions, and participants from various fields made exciting discussions in an interdisciplinal atmosphere. (Auth.)

  12. Forms of global governence

    Directory of Open Access Journals (Sweden)

    Maxim V. Kharkevich

    2014-01-01

    Full Text Available Global governance as a concept defines the meaning of contemporary world politics both as a discipline and as reality. Interdependent and globalized world requires governance, and a global government has not been formed yet. The theoretical possibility of global governance without global government is proved and justified. The purpose of this article is to analytically identify possible forms of global governance. Three such forms of global governance are identified: hierarchical, market and network. In a hierarchy the governance is due to the asymmetry of power between the parties. Market control happens via anonymous pricing mechanism. Network, in contrast to the market is characterized by a closer value link between the actors, but unlike the hierarchical relationship actors are free to leave the network. Global governance takes three forms and is being implemented by different actors. To determine the most efficient form of global governance is impossible. Efficiency depends on the match between a form and an object of government. It should be noted that meta governance is likely to remain a monopoly of institutionally strong states in global governance.

  13. Polyphony and verb forms

    Directory of Open Access Journals (Sweden)

    2012-12-01

    Full Text Available This paper examines some special uses of indicative and subjunctive verb forms in Spanish, which contemporary linguistics explains using the notions of polyphony, evidentials, echoic representation, quotatives, etc. These terms, even though they refer to different characteristics and belong to different theoretical frameworks, share one common feature: they all refer to diverse linguistic forms (discourse markers, linguistic negation, quotatives, echoic utterances, etc. characterized by the presence and interaction of different voices or points of view in one discourse sequence. In this study we are interested in a description of quotative or polyphonic meanings expressed by specific verb forms and tenses, the imperfect and the conditional, and also by indicative forms in subordinate substantive clauses with a negative main verb and by subjunctive forms in subordinate concessive clauses. Our research focuses on the analysis of the linguistic conditions that make possible the evidential use of the conditional, the imperfect and the echoic (metarepresentative interpretation of indicative and subjunctive forms in the above-mentioned contexts. The examples we discuss show that evidential and echoic interpretations are inferential meanings derived from the extralinguistic situation and the knowledge that speakers have of the world.

  14. Comparative waste forms study

    A number of alternative process and waste form options exist for the immobilization of nuclear wastes. Although data exists on the characterization of these alternative waste forms, a straightforward comparison of product properties is difficult, due to the lack of standardized testing procedures. The characterization study described in this report involved the application of the same volatility, mechanical strength and leach tests to ten alternative waste forms, to assess product durability. Bulk property, phase analysis and microstructural examination of the simulated products, whose waste loading varied from 5% to 100% was also conducted. The specific waste forms investigated were as follows: Cold Pressed and Sintered PW-9 Calcine; Hot Pressed PW-9 Calcine; Hot Isostatic Pressed PW-9 Calcine; Cold Pressed and Sintered SPC-5B Supercalcine; Hot Isostatic pressed SPC-5B Supercalcine; Sintered PW-9 and 50% Glass Frit; Glass 76-68; Celsian Glass Ceramic; Type II Portland Cement and 10% PW-9 Calcine; and Type II Portland Cement and 10% SPC-5B Supercalcine. Bulk property data were used to calculate and compare the relative quantities of waste form volume produced at a spent fuel processing rate of 5 metric ton uranium/day. This quantity ranged from 3173 L/day (5280 Kg/day) for 10% SPC-5B supercalcine in cement to 83 L/day (294 Kg/day) for 100% calcine. Mechanical strength, volatility, and leach resistance tests provide data related to waste form durability. Glass, glass-ceramic and supercalcine ranked high in waste form durability where as the 100% PW-9 calcine ranked low. All other materials ranked between these two groupings

  1. Chemical forms of radioiodine

    International Nuclear Information System (INIS)

    Tachikawa, Enzo

    1979-01-01

    Release of radioiodine built-up during reactor operations presents a potential problem from the standpoint of environmental safety. Among the chemical forms of radioiodine, depending upon the circumstances, organic iodides cast a most serious problem because of its difficulties in the trapping and because of its stability compared to other chemical forms. Furthermore, pellet-cladding interaction (PCl) fuel failures in LWR fuel rods are believed to be stress corrosion cracks caused by embrittling fission product species, radioiodine. To deal with these problems, knowledge is required on the chemical behaviors of radioiodine in and out of fuels, as well as the release behaviors from fuels. Here a brief review is given of these respects, in aiming at clearing-up the questions still remaining unknown. The data seem to indicate that radioiodine exists as a combined form in fuels. upon heating slightly irradiated fuels, the iodine atoms are released in a chemical form associated with uranium atoms. Experiments, however, as needed with specimen of higher burnup, where the interactions of radioiodine with metallic fission products could be favored. The dominant release mechanism of radioiodine under normal operating temperatures will be diffusion to grain boundaries leading to open surfaces. Radiation-induced internal traps, however, after the rate of diffusion significantly. The carbon sources of organic iodides formed under various conditions and its formation mechanisms have also been considered. (author)

  2. Here I Stand: Mediated Bodies in Dissent

    Directory of Open Access Journals (Sweden)

    D.R. Koukal

    2010-02-01

    Full Text Available Of all of the various forms of political dissent, the most dramatic as a form of expression is that which places lived bodies in tension with the prevailing social order. Bodies so presented—in marches, strikes, sit-ins, demonstrations and other mass assemblies—are just the opposite of Foucault’s docile bodies. They are a collective will concretized, an intersubjective mass animated by a common purpose that fills a public space and obstinately makes their shared demand. The presence of such dissenting bodies assembled in various public spaces have at times been essential in dramatizing grievances and re-constituting the meaning of a political landscape. Though such dissenting bodies have often been met with the full force of the state, the political efficacy of such bodies has been seriously undermined in recent years due to more subtle strategies to suppress such dissent, and counterstrategies meant to circumscribe these efforts at suppression. The goal of this essay is to explore these developments through phenomenological analysis. Preliminary considerations of (1 different forms of political potency and (2 the lived body and its movement through space, will be followed by (3 an investigation of what it means to be a dissenting body witnessed within a public place, and (4 what happens when dissenting bodies are consigned to circumscribed spaces or retreat to the “virtual.” This analysis will show how these developments have rendered dissenting bodies far less politically effective than they have been in the past, which dangerously weakens the democratic traditions of free speech and open dissent. This, in turn, supports a call (5 for a re-assertion of the embodied subject into the practice of political dissent.

    Full Text Available Today, the juxtaposition between physical bodies and the gameworld is ever more fluid. Virtual Reality headsets are available at game stores with more AAA games being created for the format. The release of the Nintendo Switch and its dynamic JoyCon controllers reintroduce haptic movement based controls.  Pokémon GO’s augmented reality took gamers outdoors and has encouraged the Harry Potter franchise to follow in its mobile footsteps. Each development encourages a step further into the digital world. At the same time, the movement of bodies always has political dimensions. We live in a world where walls seem like solutions to the movement of bodies, while the mere meeting of bodies elsewhere – for sex, marriage and other reasons – is still forbidden by many states’ rules. Games and game-like interfaces have shown the ability to bend those rules, and to sometimes project other worlds and rule systems over our world in order to make bodies move and meet. For this special issue on ‘Body Movements’, Press Start invited authors to focus on embodiment, body movements, political bodies, community bodies, virtual bodies, physical bodies, feminine, masculine, trans- bodies, agency or its lack, and anything else in between. The response to this invitation was variegated, and provocative, as outlined here.

    Pallure, V; Ameline, M; Plantin, P; Bessis, D

    2013-11-01

    Terra firma-forme (i.e. resembling dry earth) is a condition chiefly affecting children wrongly considered as dermatosis arising out of negligence and inadequate corporal hygiene. It is in fact an acquired and asymptomatic grey-brown hyperpigmentation of the skin that persists despite normal washing with soap and water, but which subsides on rubbing with isopropyl alcohol 70%. Herein we report 10 new cases of this disorder. Ten patients aged between 7 months in 17 years were seen for acquired macular skin pigmentation, either brown or grey, fragmented and confluent. In six patients, this abnormality was the main reason for the consultation, generally on aesthetic grounds, and more rarely for diagnosis or suspicion of acanthosis nigricans. In all cases, questioning revealed normal hygiene measures. The condition comprised macular or acquired papular pigmentation, either brown or grey, of bilateral and symmetrical disposition and electively affecting the neck, trunk and retro-malleolar area of the ankles. Clinical examination together with a test involving rubbing with isopropyl alcohol 70° confirmed the diagnosis, revealing healthy underlying skin. Terra firma-forme dermatosis is frequently seen in clinical practice but is largely ignored in the French literature, possibly because of relevant indifference towards the condition. It affects both sexes equally, with no predilection for age or ethnicity, although it is classically seen to a greater extent during adolescence. Diagnosis of the condition, which is easily made thanks to the hyperpigmentation of dirty brown appearance on the neck and the ankles in particular, should not mislead the practitioner into blaming patients for supposedly deficient body hygiene. Knowledge of this form of dermatosis is useful because of its potentially harmful aesthetic and social effects, despite the ease of treatment by insistent rubbing of the affected areas with medical alcohol or ether. Early recognition also avoids pointless

    D'Arcy Thompson was born in 1860, trained in Edinburgh and Cambridge, and held positions in Dundee and St Andrews, where he worked until his death in 1948. On Growth and Form , his classic work on the mathematical patterns and physical rules underlying biological forms, was first published in 1917. To learn more about the book's context, we met Matthew Jarron, Curator of Museum Services at the University of Dundee, in the University's D'Arcy Thompson Zoology Museum. Surrounded by specimens, many of which were collected by Thompson himself, we discussed the legacy of On Growth and Form and the life of the man behind it. © 2017.

Work is being conducted to determine the range of conditions under which these solidification agents can be applied to specific LLW streams. These studies are directed primarily towards defining operating parameters for both improved solidification of problem wastes and solidification of new LLW streams generated from advanced volume reduction technologies. Work is being conducted to measure relevant waste form properties. These data will be compiled and evaluated to demonstrate compliance with waste form performance and shallow land burial acceptance criteria and transportation requirements

    2015-06-01

    Body-related avoidance behavior, e.g., not looking in the mirror, is a common feature of eating disorders. It is assumed that it leads to insufficient feedback concerning one's own real body form and might thus contribute to distorted mental representation of one's own body. However, this assumption still lacks empirical foundation. Therefore, the aim of the present study was to examine the relationship between misperception of one's own body and body-related avoidance behavior in N = 78 female patients with Bulimia nervosa and eating disorder not otherwise specified. Body-size misperception was assessed using a digital photo distortion technique based on an individual picture of each participant which was taken in a standardized suit. In a regression analysis with body-related avoidance behavior, body mass index and weight and shape concerns as predictors, only body-related avoidance behavior significantly contributed to the explanation of body-size overestimation. This result supports the theoretical assumption that body-related avoidance behavior makes body-size overestimation more likely.

    Full Text Available Address forms constitute an integral part of Basotho sociolinguistic etiquette. They are regarded as a kind of emotional capital that may be invested in putting others at ease. They are indicators of deference, politeness and markers of social distance. (Fasold 1990, Akindele 1990, 1991, 1993 This paper examines the address forms used by the Basotho people. It analyzes and discusses the various types and the factors determining their use. The discussion of address forms in Sesotho focuses on First Name, Title plus First Name, Title plus Last Name, Nickname, Multiple Names, and Teknonym. Drawing data from semi-literate and literate urban and rural population of Maseru district of Lesotho, it was found that the commonest form of address used by the Basotho people is title plus first name. e.g. ntate Thabo (father Thabo, 'm'e Puleng (mother Puleng, ausi Maneo (sister Maneo, abuti Mahao (brother Mahao.

    Introduction Foreign body in the oral cavity may be asymptomatic for long time and only sometimes it can lead to a typical granulomatous foreign body reaction. Some patients may complain of oral pain and present signs of inflammation with purulent discharge. A granuloma is a distinct, compact microscopic structure composed of epithelioid-shaped macrophages typically surrounded by a rim of lymphocytes and filled with fibroblasts and collagen. Nowadays, the increase of cosmetic invasive procedures such as injection of prosthetic materials in lips and cheeks may lead to unusual forms of inflammatory granulomas. Objectives Describe an unusual presentation of a foreign body reaction in the buccal mucosa due to previous injection of cosmetic agent. Resumed Report A 74-year-old woman was referred to the Department of Otorhinolaryngology, Head and Neck Surgery to investigate the presence of multiple painless, bilateral nodules in the buccal mucosa, with progressive growth observed during the previous 2 months. The histologic results showed a foreign body inflammatory reaction. Conclusion Oral granulomatosis lesions represent a challenging diagnosis for clinicians and a biopsy may be necessary. Patients may feel ashamed to report previous aesthetic procedures, and the clinicians must have a proactive approach.

    2016-01-01

    Full Text Available The paper presents an overview of results for wing-body interference, obtained by the author for varied wing-body combinations. The lift-curve slopes of the wing-body combinations are considered. In this paper a discrete vortices method (DVM and 2D potential model for cross-flow around fuselage are used. The circular and elliptical cross-sections of the fuselage and flat wings of various forms are considered. Calculations showed that the value of the lift-curve slopes of the wing-body combinations may exceed the same value for an isolated wing. This result confirms an experimental data obtained by other authors earlier. Within a framework of the used mathematical models the investigations to optimize the wing-body combination were carried. The present results of the optimization problem for the wing-body combination allowed to select the optimal geometric characteristics for configuration to maximize the values of the lift-curve slopes of the wing-body combination. It was revealed that maximums of the lift-curve slopes for the optimal mid-wing configuration with elliptical cross-section body had a sufficiently large relative width of the body (more than 30% of the span wing.

    In this program, contemporary solidification agents are being investigated relative to their applications to major fuel cycle and non-fuel cycle low-level waste (LLW) streams. Work is being conducted to determine the range of conditions under which these solidification agents can be applied to specific LLW streams. These studies are directed primarily towards defining operating parameters for both improved solidification of problem wastes and solidification of new LLW streams generated from advanced volume reduction technologies. Work is being conducted to measure relevant waste form properties. These data will be compiled and evaluated to demonstrate compliance with waste form performance and shallow land burial acceptance criteria and transportation requirements (both as they exist and as they are modified with time). 6 tables

It is not a pivotal concept in Wittgenstein’s philosophy. But it is a minor signpost of a major reorientation of philosophy, philosophy of language and logic, and philosophy of mathematics that Wittgenstein instigated. For Wittgenstein sought to replace the conception of a language as a meaning calculus (Frege, Russell, the Tractatus by an anthropological or ethnological conception. A language is not a class of sentences that can be formed from a set of axioms (definitions, formation and transformation rules and the meanings of which is given by their truth-conditions, but an open-ended series of interlocking language-games constituting a form of life or way of living (a culture. Wittgenstein’s uses of ‘Lebensform’ and its cognates, both in the Investigations and in his Nachlass are severally analysed, and various exegetical misinterpretations are clarified.

    Allen, Loyd V

    2008-11-01

    Drugs must be properly formulated for administration to patients, regardless of age. Pediatric patients provide some additional challenges to the formulator in terms of compliance and therapeutic efficacy. Due to the lack of sufficient drug products for the pediatric population, the pharmaceutical industry and compounding pharmacies must develop and provide appropriate medications designed for children. The purpose of this article was to review the physical, chemical, and biological characteristics of drug substances and pharmaceutical ingredients to be used in preparing a drug product. In addition, stability, appearance, palatability, flavoring, sweetening, coloring, preservation, packaging, and storage are discussed. Information for the current article was gathered from a literature review; from presentations at professional and technical meetings; and from lectures, books, and publications of the author, as well as from his professional experience. Professional society meetings and standards-setting bodies were also used as a resource. The proper design and formulation of a dosage form requires consideration of the physical, chemical, and biological characteristics of all of the drug substances and pharmaceutical ingredients (excipients) to be used in fabricating the product. The drug and pharmaceutical materials utilized must be compatible and produce a drug product that is stable, efficacious, palatable, easy to administer, and well tolerated. Preformulation factors include physical properties such as particle size, crystalline structure, melting point, solubility, partition coefficient, dissolution, membrane permeability, dissociation constants, and drug stability. Successful development of a formulation includes multiple considerations involving the drug, excipients, compliance, storage, packaging, and stability, as well as patient considerations of taste, appearance, and palatability.

  1. Proximity Interactions among Basal Body Components in Trypanosoma brucei Identify Novel Regulators of Basal Body Biogenesis and Inheritance

    Directory of Open Access Journals (Sweden)

    Hung Quang Dang

    2017-01-01

    Full Text Available The basal body shares similar architecture with centrioles in animals and is involved in nucleating flagellar axonemal microtubules in flagellated eukaryotes. The early-branching Trypanosoma brucei possesses a motile flagellum nucleated from the basal body that consists of a mature basal body and an adjacent pro-basal body. Little is known about the basal body proteome and its roles in basal body biogenesis and flagellar axoneme assembly in T. brucei. Here, we report the identification of 14 conserved centriole/basal body protein homologs and 25 trypanosome-specific basal body proteins. These proteins localize to distinct subdomains of the basal body, and several of them form a ring-like structure surrounding the basal body barrel. Functional characterization of representative basal body proteins revealed distinct roles in basal body duplication/separation and flagellar axoneme assembly. Overall, this work identified novel proteins required for basal body duplication and separation and uncovered new functions of conserved basal body proteins in basal body duplication and separation, highlighting an unusual mechanism of basal body biogenesis and inheritance in this early divergent eukaryote.

    A bipolar pulse forming transmission line module for linear induction accelerators having first, second, third, fourth, and fifth planar conductors which form an interleaved stack with dielectric layers between the conductors. Each conductor has a first end, and a second end adjacent an acceleration axis. The first and second planar conductors are connected to each other at the second ends, the fourth and fifth planar conductors are connected to each other at the second ends, and the first and fifth planar conductors are connected to each other at the first ends via a shorting plate adjacent the first ends. The third planar conductor is electrically connectable to a high voltage source, and an internal switch functions to short a high voltage from the first end of the third planar conductor to the first end of the fourth planar conductor to produce a bipolar pulse at the acceleration axis with a zero net time integral. Improved access to the switch is enabled by an aperture through the shorting plate and the proximity of the aperture to the switch.

  3. Does body image influence the relationship between body weight and breastfeeding maintenance in new mothers?

    2017-09-01

    Obese women have lower breastfeeding initiation and maintenance rates than healthy weight women. Research generally focuses on biomedical explanations for this. Psychosocial factors including body image and well-being after childbirth are less well understood as predictors of breastfeeding. In obese and healthy weight women, we investigated changes in body image between 72 hrs post-delivery and 6-8 weeks post-natal, studying how women's body image related to breastfeeding initiation and maintenance. We also investigated how psychological distress was related to body image. Longitudinal semi-structured questionnaire survey. Body image and psychological distress were assessed within 72 hrs of birth and by postal questionnaire at 6-8 weeks, for 70 obese and 70 healthy weight women initiating exclusive (breastmilk only) breastfeeding or mixed feeding (with formula milk) in hospital. Breastfeeding was re-assessed at 6-8 weeks. Obese women were less likely to exclusively breastfeed in hospital and maintain breastfeeding to 6-8 weeks. Better body image was related to maintaining breastfeeding and to lower post-natal psychological distress for all women, but education level was the most significant predictor of maintenance in multivariate regression including body image and weight status. Body image mediated, but did not moderate the relationship between weight and breastfeeding maintenance. Body image was lower overall in obese women, but all women had low body image satisfaction around childbirth, reducing further at 6-8 weeks. Health professionals should consider women's body image when discussing breastfeeding. A focus on breast function over form may support breastfeeding for all women. Statement of contribution What is already known on this subject? Obesity can negatively affect breastfeeding initiation and maintenance, but there is little information about how psychosocial factors affect this relationship. Body image may be an important factor, but has not

  5. How our body influences our perception of the world

    2015-06-01

    Full Text Available Incorporating the fact that the senses are embodied is necessary for an organism to interpret sensory information. Before a unified perception of the world can be formed, sensory signals must be processed with reference to body representation. The various attributes of the body such as shape, proportion, posture, and movement can be both derived from the various sensory systems and can affect perception of the world (including the body itself. In this review we examine the relationships between sensory and motor information, body representations, and perceptions of the world and the body. We provide several examples of how the body affects perception (including but not limited to body perception. First we show that body orientation effects visual distance perception and object orientation. Also, visual-auditory crossmodal-correspondences depend on the orientation of the body: audio high frequencies correspond to a visual up defined by both gravity and body coordinates. Next, we show that perceived locations of touch is affected by the orientation of the head and eyes on the body, suggesting a visual component to coding body locations. Additionally, the reference-frame used for coding touch locations seems to depend on whether gaze is static or moved relative to the body during the tactile task. The perceived attributes of the body such as body size, affect tactile perception even at the level of detection thresholds and two-point discrimination. Next, long-range tactile masking provides clues to the posture of the body in a canonical body schema. Finally, ownership of seen body parts depends on the orientation and perspective of the body part in view. Together, all of these findings demonstrate how sensory and motor information, body representations, and perceptions (of the body and the world are interdependent.

    The human body generates heat capable of raising body temperature by approximately 1°C per hour. Normally, this heat is dissipated by means of a thermoregulatory system. Disorders resulting from abnormally high or low body temperature result in neurologic dysfunction and pose a threat to life. In response to thermal stress, maintenance of normal body temperature is primarily maintained by convection and evaporation. Hyperthermia results from abnormal temperature regulation, leading to extremely elevated body temperature while fever results from a normal thermoregulatory mechanism operating at a higher set point. The former leads to specific clinical syndromes with inability of the thermoregulatory mechanism to maintain a constant body temperature. Heat related illness encompasses heat rash, heat cramps, heat exhaustion and heat stroke, in order of severity. In addition, drugs can induce hyperthermia and produce one of several specific clinical syndromes. Hypothermia is the reduction of body temperature to levels below 35°C from environmental exposure, metabolic disorders, or therapeutic intervention. Management of disorders of body temperature should be carried out decisively and expeditiously, in order to avoid secondary neurologic injury. © 2014 Elsevier B.V. All rights reserved.

    2017-09-02

    Inclusion bodies are often formed when the foreign protein is over expressed in Escherichia coli. Since proteins in inclusion bodies are inactive, denaturing and refolding of inclusion body proteins are necessary to obtain the active form. Instead of the conventional denaturants, urea and guanidine hydrochloride, a strong anionic detergent SDS was used to solubilize C-terminal His-tag form of ulvan lyase in the inclusion bodies. Solution containing SDS-solubilized enzyme were kept on ice to precipitate SDS, followed by SDS-KCl insoluble crystal formation to remove SDS completely. After removing the precipitate by centrifugation, the supernatant was applied to Ni-NTA column to purify His-tagged ulvan lyase. The purified protein showed a dimeric form and ulvan lyase activity, demonstrating that SDS-denatured protein was renatured and recovered enzyme activity. This simple method could be useful for refolding other inclusion body proteins. Copyright © 2017 Elsevier Inc. All rights reserved.

  15. Nuclear body formation and PML body remodeling by the human cytomegalovirus protein UL35

    International Nuclear Information System (INIS)

    Salsman, Jayme; Wang Xueqi; Frappier, Lori

    2011-01-01

    The human cytomegalovirus (HCMV) UL35 gene encodes two proteins, UL35 and UL35a. Expression of UL35 in transfected cells results in the formation of UL35 nuclear bodies that associate with promyelocytic leukemia (PML) protein. PML forms the basis for PML nuclear bodies that are important for suppressing viral lytic gene expression. Given the important relationship between PML and viral infection, we have further investigated the association of UL35 with PML bodies. We demonstrate that UL35 bodies form independently of PML and subsequently recruit PML, Sp100 and Daxx. In contrast, UL35a did not form bodies; however, it could bind UL35 and inhibit the formation of UL35 bodies. The HCMV tegument protein pp71 promoted the formation of UL35 bodies and the cytoplasmic localization of UL35a. Similarly, UL35a shifted pp71 to the cytoplasm. These results indicate that the interplay between UL35, UL35a and pp71 affects their subcellular localization and likely their functions throughout infection.

    A case of a 41-year-old patient presenting late post-trauma with out any major signs or symptoms is presented herewith. On radiological investigation, a peculiar foreign body was identified in the orbital floor. To our surprise the point of entry of the foreign body was not proportionate with the size of it. Moreover, the trajectory and final location of foreign body did not concur with the symptom less presentation of patient. After what was thought to be adequate investigation, the patient was taken under general anaesthesia to reveal an additional foreign body that put most of the preoperative queries to rest. This case in retrospect emphasises the need for ruling out foreign body in the case of any penetrating injury of orbit with the help of not just radiographs and CT scans but also ultrasonography and MRI.

    Full Text Available Orbital pseudotumor is a benign disease involving the orbital structures. Pseudotumor of the ciliary body is rare. We present a case of a 27-year-old male who presented with gradual visual loss, pain, and redness in his left eye. On examination he was found to have a yellowish white mass at the periphery of anterior chamber in his left eye and ultrasound biomicroscopy (UBM revealed a ciliary body mass in the same eye. He was treated with systemic steroids, which was tapered over a period of 8 weeks. His symptoms improved and the ciliary body mass disappeared with no recurrence over the next 6 months. UBM is an important diagnostic tool for diagnosing ciliary body mass. Early diagnosis and prompt treatment with systemic steroids may help resolve pseudotumor of the ciliary body.

    It is pointed out that the correct criterion to define the legal PQCD contribution to the exclusive processes in the lightcone perturbative expansion should be based on the large off-shellness of the lightcone energy in the intermediate states. In the lightcone perturbative QCD calculation of the pion form factor, the authors find that the legal PQCD contribution defined by the lightcone energy cut saturates in the smaller Q{sup 2} region compared to that defined by the gluon four-momentum square cut. This is due to the contribution by the highly off-energy-shell gluons in the end point regions of the phase space, indicating that the gluon four-momentum-square cut may have cut too much to define the legal PQCD.

    Full Text Available Modern studies emphasized on the needs of researching the hospitality as relevant aspects of tourism and hospitality fields. Anyway, these approaches are inextricably intertwined to the industry of tourism and do not take seriously the anthropological and sociological roots of hospitality. In fact, the hotel seems to be a partial sphere of hospitality at all. Under this context, the present paper explores the issue of hospitality enrooted in the political and economic indo-European principle of free-transit which is associated to a much broader origin.  Starting from the premise etymologically hostel and hospital share similar origins, we follow the contributions of J Derrida to determine the elements that formed the hospitality up to date.

    2009-07-01

    The (ONOO)- anion, known as peroxynitrite, is characterized by a singlet spin state. A new stable dimer form of peroxynitrite [NO-O2]- in the triplet state at distances close to r(O-N) ≈ 2.885 Å between oxygen in the O2 structure and nitrogen has been established within the quantum-chemical CASSCF approximation. The vibrational motion of the dimer is significantly anharmonic; for the 16O and 14N isotopes, the differences in the energies of two neighboring levels correspond to frequencies of about 70-30 cm-1. The triplet dimer structure retains stability in the case of interaction with water molecules. The activation barriers caused by rearrangement of the peroxynitrite structure into the ground state of the NO{3/-} anion with the symmetry D 3 h are found.

    There has been much activity in the measurement of the elastic electromagnetic proton and neutron form factors in the last decade, and the quality of the data has greatly improved by performing double polarization experiments, in comparison with previous unpolarized data. Here we review the experimental data base in view of the new results for the proton, and neutron, obtained at JLab, MAMI, and MIT-Bates. The rapid evolution of phenomenological models triggered by these high-precision experiments will be discussed, including the recent progress in the determination of the valence quark generalized parton distributions of the nucleon, as well as the steady rate of improvements made in the lattice QCD calculations.

    Full Text Available The contributions of Discourse Analysis towards the methodological challenges for reading practices within a historical and social dimension are investigated. In fact, social practices are also a result of imaginary constructions. The relationship between history and language should be taken into account so that the place of practices could be considered in a discursive dimension. In other words, language and its permanent functioning should be expressed by opacity and by the political stance within the incompleteness and evasive character of language. An analysis will be provided in which plasticity, as a result of the fluidity that circulates in the cyberspace, produces the illusion of freedom and consequently a greater movement of the subjects in their discourse. A form of the subjective relationship with the body in current society will be given and how this relationship is dealt with by the trend in making a spectacle of the body. In this sense, the language of the body is foregrounded on ideology, by a play of forces, producing the unfolding of an image-discourse, constituting memories and silencing certain practices.

  6. Boost Your Body: Self-Improvement Magazine Messages Increase Body Satisfaction in Young Adults.

    The verbal messages that contextualize exposure to idealized body imagery may moderate media users' body satisfaction. Such contextualizing verbal messages often take the form of social comparison motives in fashion magazines, while body dissatisfaction is an important mechanism underlying various body image-related health issues like depression and unbalanced weight status. Hence, the present study applied social comparison motives as induced through magazine cover messages. Hypotheses were tested in an experimental design with social comparison motives (self-improvement vs. self-evaluation vs. control) and recipient gender as between-subjects factors and body satisfaction as within-subjects factor (N = 150). Results showed that self-improvement messages accompanying ideal body media models increased body satisfaction, compared to control messages and baseline measures. In contrast, the self-evaluation messages did not impact body satisfaction. Results imply that inconsistencies regarding effects from exposure to idealized body imagery are explained by the context in which media images are portrayed, evoking differential social comparison motives. Moreover, the findings imply that health communication interventions can use verbal messages on body improvement as helpful tools, if they draw on social comparison motives effectively.

    Nowadays, in developed countries there are standards of beauty based on pro-thin models, which are internalized by adolescents and young people especially in the case of women, assuming it as risk factor for developing changes in body image and perception. To analyze the current state of research in relation to body image, the sociodemographic variables that influence it, the relationship between body composition, conducting diets, eating disorders, sports and intervention programs and prevention, and the body image. It was searched in Medline, Isi Web of knowledge and Dialnet as well as a manual search among the references of selected studies and in different libraries. A increased socio-cultural influence is associated with a greater perception of body fat, greater body image dissatisfaction and lower self assessment of overall fitness. This leads to a lot of teenagers and young adults to abuse to the restrictive diets and to suffer eating disorders. Numerous studies have analyzed the relationship between sports practice with body image disturbance; there are conflictive results. Moreover it is necessary to design objective tools to detect changes and enhance the design of prevention and intervention programs in order to avoid distortion of body image, especially in those age ranges where the population is more vulnerable to this phenomenon. The excessive current preoccupation about body image has resulted in the realization of diets and changes as eating disorders. There are other factors that influence body image and perception as the realization of physical exercise, although the results about the relationship between these factors are contradictory. Therefore, further work is needed on the issue by creating tools to detect changes and enhance the design of prevention and intervention programs. Copyright © AULA MEDICA EDICIONES 2013.

  8. Phase separation and the formation of cellular bodies

    Xu, Bin; Broedersz, Chase P.; Meir, Yigal; Wingreen, Ned S.

    Cellular bodies in eukaryotic cells spontaneously assemble to form cellular compartments. Among other functions, these bodies carry out essential biochemical reactions. Cellular bodies form micron-sized structures, which, unlike canonical cell organelles, are not surrounded by membranes. A recent in vitro experiment has shown that phase separation of polymers in solution can explain the formation of cellular bodies. We constructed a lattice-polymer model to capture the essential mechanism leading to this phase separation. We used both analytical and numerical tools to predict the phase diagram of a system of two interacting polymers, including the concentration of each polymer type in the condensed and dilute phase.

    A CMC article and process for producing the article to have a layer on its surface that protects a reinforcement material within the article from damage. The method entails providing a body containing a ceramic reinforcement material in a matrix material that contains a precursor of a ceramic matrix material. A fraction of the reinforcement material is present and possibly exposed at a surface of the body. The body surface is then provided with a surface layer formed of a slurry containing a particulate material but lacking the reinforcement material of the body. The body and surface layer are heated to form the article by converting the precursor within the body to form the ceramic matrix material in which the reinforcement material is contained, and by converting the surface layer to form the protective layer that covers any fraction of the reinforcement material exposed at the body surface.

  11. Cavitation During Superplastic Forming

    Directory of Open Access Journals (Sweden)

    John Campbell

    2011-07-01

    Full Text Available Cavitation is the opening of pores during superplastic forming, typically at grain boundary triple points or on second phase grain boundary particles during slip of grain boundaries. Theories for the initiation of cavitation are reviewed. It seems that cavitation is unlikely to occur by processes intrinsic to metals such as dislocation mechanisms or point defect condensation. It is proposed that cavitation can only occur at non-bonded interfaces such as those introduced extrinsically (i.e., from the outside during the original casting of the metal. These defects, known as oxide bifilms, are naturally introduced during pouring of the liquid metal, and are frozen into the solid, often pushed by dendritic growth into grain boundaries where they are difficult to detect because of their extreme thinness, often measured in nanometres. Their unbonded central interface acts as a crack and can initiate cavitation. Second phase precipitates probably do not nucleate and grow on grain boundaries but grow on bifilms in the boundaries, explaining the apparent association between boundaries, second phase particles and failure initiation. Improved melting and casting techniques can provide metal with reduced or zero bifilm population for which cavitation would not be possible, promising significant improvements in superplastic behaviour.

    Full Text Available Body dysmorphic disorder is a type of mental illness, wherein the affected person is concerned with body image, manifested as excessive concern about and preoccupation with a perceived defect of their physical features. Although it is a common disease and has been defined in the literature over a century, it is not a well known disease. Chronic, treatment resistant and sometimes delusional nature could result in severe functional impairment. The diagnosis and appropriate therapy of disorder are crucial because of increased suicidality and reduction in life quality. In this article the symptoms, etiology, clinical features and treatment of body dysmorphic disorder are briefly reviewed.

  17. Visual body recognition in a prosopagnosic patient.

    2012-01-01

    Conspicuous deficits in face recognition characterize prosopagnosia. Information on whether agnosic deficits may extend to non-facial body parts is lacking. Here we report the neuropsychological description of FM, a patient affected by a complete deficit in face recognition in the presence of mild clinical signs of visual object agnosia. His deficit involves both overt and covert recognition of faces (i.e. recognition of familiar faces, but also categorization of faces for gender or age) as well as the visual mental imagery of faces. By means of a series of matching-to-sample tasks we investigated: (i) a possible association between prosopagnosia and disorders in visual body perception; (ii) the effect of the emotional content of stimuli on the visual discrimination of faces, bodies and objects; (iii) the existence of a dissociation between identity recognition and the emotional discrimination of faces and bodies. Our results document, for the first time, the co-occurrence of body agnosia, i.e. the visual inability to discriminate body forms and body actions, and prosopagnosia. Moreover, the results show better performance in the discrimination of emotional face and body expressions with respect to body identity and neutral actions. Since FM's lesions involve bilateral fusiform areas, it is unlikely that the amygdala-temporal projections explain the relative sparing of emotion discrimination performance. Indeed, the emotional content of the stimuli did not improve the discrimination of their identity. The results hint at the existence of two segregated brain networks involved in identity and emotional discrimination that are at least partially shared by face and body processing.

  18. Forms of War

    Vogel, H.; Bartelt, D.

    2007-01-01

    Purpose: Under war conditions, employed weapons can be identified on radiographs obtained in X-ray diagnostic. The analysis of such X-ray films allows concluding that there are additional information about the conditions of transport and treatment; it shall be shown that there are X-ray findings which are typical and characteristic for certain forms of warfare. Material and method: The radiograms have been collected during thirty years; they come from hospitals, where war casualties had been treated, and personal collections. Results: The material is selected, because in war X-ray diagnostic will be limited and the interest of the opposing parties influence the access to the material; furthermore the possibilities to publish or to communicate facts and thoughts are different. Citizens of the USA, GB, France, or Israel will have easier access to journals than those of Vietnam, Chad, and Zimbabwe. Under war conditions, poor countries, like North Vietnam may develop own concepts of medical care. There are X-ray findings which are typical or even characteristic for air warfare, guerrilla warfare, gas war, desert warfare, conventional warfare, and annihilation warfare, and city guerrilla warfare/civil war. The examples demonstrate that weapons and the conditions of transport and treatment can be recognized by X-ray findings. The radiogram can be read like a document. Conclusion: In War, there are differences between a treatment and imaging diagnostic in countries, which control the air space and in those who do not. Medical care of the poor, i.e. in countries (in general those opposing the western nations) will hardly be published, and poverty has no advocate

    When suggesting for discussion a possible role and the utility of an international body for an internationally monitored retrievable storage system (IMRSS), it appears useful to consider its possible advantages and disadvantages to also assess the potential of successfully implementing such a body in the medium or long term. To stimulate such discussion is the purpose of the remainder of this paper. Moreover, the question needs to be discussed whether there could be a unique format for an IMRSS governing body or various degrees of decentralization oriented, for example, at the physical locations of relevant IMRSS facilities. The main difficulties with solutions that include responsibilities of an international IMRSS body for property, right of use, safeguards, or other issues of a more legal and/or administrative nature are discussed

    Directory of Open Access Journals (Sweden)

    1993-01-01

    Full Text Available Retained intraorbital organic foreign bodies, particularly wooden, are commonly encountered in ophthalmologic practice. We treated two children who had sustained such injury while playing. They presented to us with non-healing sinus with purulent discharge. In one of the patients, X-rays and CT scan helped to clinch the diagnosis, whereas in the other patient diagnosis was possible by correlating history with clinical findings. Surgical exploration in both patients helped us to remove the foreign bodies. Surprisingly, both the foreign bodies were 7 cm long wooden pieces. We, however, caution that management of such cases should be conservative and that surgical exploration be done only in case of complication. From our experience, we recommend proper localisation by all possible means, blunt dissection, careful haemostasis coupled with excellent lighting and exposure in the atraumatic removal of intraorbital foreign bodies.

Further, a method of forming the capacitor assembly is also presented.

  18. Scattering Length Scaling Laws for Ultracold Three-Body Collisions

    International Nuclear Information System (INIS)

    D'Incao, J.P.; Esry, B.D.

    2005-01-01

    We present a simple and unifying picture that provides the energy and scattering length dependence for all inelastic three-body collision rates in the ultracold regime for three-body systems with short-range two-body interactions. Here, we present the scaling laws for vibrational relaxation, three-body recombination, and collision-induced dissociation for systems that support s-wave two-body collisions. These systems include three identical bosons, two identical bosons, and two identical fermions. Our approach reproduces all previous results, predicts several others, and gives the general form of the scaling laws in all cases

    Seizures that are resistant to standard medications remain a major clinical problem. One underutilized option for patients with medication-resistant seizures is the high-fat, low-carbohydrate ketogenic diet. The diet received its name based on the observation that patients consuming this diet produce ketone bodies (e.g., acetoacetate, β-hydroxybutyrate, and acetone). Although the exact mechanisms of the diet are unknown, ketone bodies have been hypothesized to contribute to the anticonvulsant...

  1. Male Body Contouring.

    Singh, Babu; Keaney, Terrence; Rossi, Anthony M

    2015-09-01

    Men are increasingly turning to dermatologists and plastic surgeons to request procedures that correct or enhance physical features. With the advent of this emerging new patient population, alterations in preexisting aesthetic techniques, gender-specific uses of existing devices and overall approaches need to be revisited and adapted to obtain results that are suitable for the male patient. Recently, body contouring has become one of the most sought out procedures by men. Although the majority of clinical studies involving body contouring esthetics are performed with female patients, gains from such studies can be extrapolated to men. Body contouring can be broadly classified as non-invasive or invasive, depending on the modality used. Non-invasive contouring is most frequently performed with devices that target subcutaneous adipose with focused electrical or thermal energy, including low-level laser, cryolipolysis, ultrasonography, and radiofrequency. Invasive body contouring modalities useful for male body contouring include liposuction, pectoral and abdominal wall etching, jawline fillers, synthetic deoxycholic acid injections, and solid silicone implants. The purpose of this review is to bring attention to the unique aspects, strategies, and modalities used in aesthetic body contouring for the male patient.

    n this paper we consider the two-body problem of a spherical pseudo-rigid body and a rigid sphere. Due to the rotational and "re-labelling" symmetries, the system is shown to possess conservation of angular momentum and circulation. We follow a reduction procedure similar to that undertaken...... in the study of the two-body problem of a rigid body and a sphere so that the computed reduced non-canonical Hamiltonian takes a similar form. We then consider relative equilibria and show that the notions of locally central and planar equilibria coincide. Finally, we show that Riemann's theorem on pseudo......-rigid bodies has an extension to this system for planar relative equilibria....

  4. Magnetic form factors of the trinucleons

    Energy Technology Data Exchange (ETDEWEB)

    Schiavilla, R; Pandharipande, V R; Riska, Dan-Olof

    1989-11-01

    The magnetic form factors of 3H and 3He are calculated with the Monte Carlo method from variational ground-state wave functions obtained for the Argonne and Urbana two- and three-nucleon interactions. The electromagnetic current operator contains one- and two-body terms that are constructed so as to satisfy the continuity equation with the two-nucleon potential in the Hamiltonian. The results obtained with the Argonne two-nucleon interaction are in overall agreement with the empirical values. It appears that the remaining theoretical uncertainty, in the calculation of these form factors from a given interaction model, is dominated by that in the electromagnetic form factors of the nucleon. It is found that the isovector magnetic form factors are rather sensitive to the details of the isospin-dependent tensor force, and they are much better reproduced with the Argonne than the Urbana potential. The isoscalar magnetic form factors appear to be sensitive to the spin-orbit interactions, and are better reproduced with the Urbana potential. The Argonne potential has a stronger τ1∙τ2 tensor force, while the Urbana one has a shorter-range spin-orbit interaction.

  6. Managing Regulatory Body Competence

    International Nuclear Information System (INIS)

    2013-01-01

    In 2001, the IAEA published TECDOC 1254, which examined the way in which the recognized functions of a regulatory body for nuclear facilities results in competence needs. Using the systematic approach to training (SAT), TECDOC 1254 provided a framework for regulatory bodies for managing training and developing and their maintaining their competence. It has been successfully used by many regulators. The IAEA has also introduced a methodology and an assessment tool - Guidelines for Systematic Assessment of Regulatory Competence Needs (SARCoN) - which provides practical guidance on analysing the training and development needs of a regulatory body and, through a gap analysis, guidance on establishing competence needs and how to meet them. In 2009, the IAEA established a steering committee (supported by a bureau) with the mission to advise the IAEA on how it could best assist Member States to develop suitable competence management systems for their regulatory bodies. The committee recommended the development of a safety report on managing staff competence as an integral part of a regulatory body's management system. This Safety Report was developed in response to this request. It supersedes TECDOC 1254, broadens its application to regulatory bodies for all facilities and activities, and builds upon the experience gained through the application of TECDOC 1254 and SARCoN and the feedback received from Member States. This Safety Report applies to the management of adequate competence as needs change, and as such is equally applicable to the needs of States 'embarking' on a nuclear power programme. It also deals with the special case of building up the competence of regulatory bodies as part of the overall process of establishing an 'embarking' State's regulatory system

    2016-01-01

    Full Text Available Incremental forming is a process to produce sheet metal parts in quick. Because there is no need for dedicated dies and molds, this process is less cost and time spent. The purpose of this study is to investigate forming forces in single point incremental forming. Producing a cone frustum of aluminum is tested for forming forces. A dynamometer is used to collect forming forces and analyze them. These forces are compared with cutting forces upon producing same geometrical shapes of experimental parts. The forming forces in Z direction are 40 times larger than the machining forces. A spindle and its axis of a forming machine should be designed enough to withstand the forming forces.

  9. Method of forming grooves in the [011] crystalline direction

    1977-01-01

    An A-B etchant is applied to a (100) surface of a body of semiconductor material, a portion of which along the (100) surface of the body is either gallium arsenide or gallium aluminum arsenide. The etchant is applied for at least 15 seconds at a temperature of approximately 80.degree. C. The A-B etchant is a solution by weight percent of 47.5%, water, 0.2% silver nitrate, 23.8% chromium trioxide and 28.5% of a 48% aqueous solution of hydrofluoric acid. As a result of the application of the A-B etchant a pattern of elongated etch pits form having their longitudinal axes along the [011] crystalline direction. Grooves are formed in the body at a surface opposite the (100) surface on which was applied the etchant. The grooves are formed along the [011] crystalline direction by aligning the longitudinal axes of the grooves with the longitudinal axes of the etch pits.

    Full Text Available The present study aims to investigate the relationship between culture and body image. We intend to know how socio-cultural factors influence the levels of satisfaction with body image. The emphasis is given to the cultural values as represented by the sociocultural norms of societies such as the United States of America and Europe. It is argued that through the media, the values of these industrialized societies are dissipated throughout the world provoking cultural changes and uniformization of behavioural standards. From the literature review, it is possible to conclude that body dissatisfaction is a reality to both sexes and a direct result of the non-conformity to cultural-esthetical patterns promoted by the profit-oriented societies.

    If a black hole can accrete a body whose spin or charge would send the black hole parameters over the extremal limit, then a naked singularity would presumably form, in violation of the cosmic censorship conjecture. We review some previous results on testing cosmic censorship in this way using the test body approximation, focusing mostly on the case of neutral black holes. Under certain conditions a black hole can indeed be over-spun or over-charged in this approximation, hence radiative and self-force effects must be taken into account to further test cosmic censorship.

  2. Thoughts on the nude body

    Directory of Open Access Journals (Sweden)

    Paolo Fabbri

    2016-07-01

    Full Text Available The image of nude appears to have ‘moved’, both because of the shift in our gaze and its point of reference. That is, unless this ‘negative emphasis’ is seen only as the uncri­ti­cal acceptance of that ‘polarizing question’ that declared the end of Clas­sical art and the decisive advent of modernity or as the effect of an hermeneutic excess ‒ of a philosophical definition of the nude impli­cit in our figurative culture – is it now the moment to go beyond the observation of the canonic nude and to develop new approaches to nudity? Despite its obviousness, the nude, too, is difficult to define. Where does the garment begin and the gown end? The skin and the flesh? How are we to describe the for­ces, movements and gestures of the body and its involucres? I will argue that the nude should be neither a pictorial genre nor a philosophical concept, but a «thought of the body» (De Chirico. It is an aesthetic figure with the power of affection and perception, but also a conceptual figure. It is not a ‘critical operator’ ‒ a cognitive ‘walk-on’ or extra ‒ but an actor with the power of speech, capable of forming and transforming new relationships with observers.

    Full Text Available INTRODUCTION: Body Integrity Identity Disorder (BIID is a rare, infrequently studied and highly secretive condition in which there is a mismatch between the mental body image and the physical body. Subjects suffering from BIID have an intense desire to amputate a major limb or severe the spinal cord in order to become paralyzed. Aim of the study is to broaden the knowledge of BIID amongst medical professionals, by describing all who deal with BIID. METHODS: Somatic, psychiatric and BIID characteristic data were collected from 54 BIID individuals using a detailed questionnaire. Subsequently, data of different subtypes of BIID (i.e. wish for amputation or paralyzation were evaluated. Finally, disruption in work, social and family life due to BIID in subjects with and without amputation were compared. RESULTS: Based on the subjects' reports we found that BIID has an onset in early childhood. The main rationale given for their desire for body modification is to feel complete or to feel satisfied inside. Somatic and severe psychiatric co-morbidity is unusual, but depressive symptoms and mood disorders can be present, possibly secondary to the enormous distress BIID puts upon a person. Amputation and paralyzation variant do not differ in any clinical variable. Surgery is found helpful in all subjects who underwent amputation and those subjects score significantly lower on a disability scale than BIID subjects without body modification. CONCLUSIONS: The amputation variant and paralyzation variant of BIID are to be considered as one of the same condition. Amputation of the healthy body part appears to result in remission of BIID and an impressive improvement of quality of life. Knowledge of and respect for the desires of BIID individuals are the first steps in providing care and may decrease the huge burden they experience.

    The aim of this study was to clarify the role of the erythrocyte inclusions found during the hematological screening of loggerhead population of the Mediterranean Sea. We studied the erythrocyte inclusions in blood specimens collected from six juvenile and nine adult specimens of the loggerhead turtle, Caretta caretta, from the Adriatic and Tyrrhenian Seas. Our study indicates that the percentage of mature erythrocytes containing inclusions ranged from 3 to 82%. Each erythrocyte contained only one round inclusion body. Inclusion bodies stained with May Grünwald-Giemsa show that their cytochemical and ultrastructure characteristics are identical to those of human Heinz bodies. Because Heinz bodies originate from the precipitation of unstable hemoglobin (Hb) and cause globular osmotic resistance to increase, we analyzed loggerhead Hb using electrophoresis and high-performance liquid chromatography to detect and quantitate Hb fractions. We also tested the resistance of Hb to alkaline pH, heat, isopropanol denaturation, and globular osmosis. Our hemogram results excluded the occurrence of any infection, which could be associated with an inclusion body, in all the specimens. Negative Feulgen staining indicated that the inclusion bodies are not derived from DNA fragmentation. We hypothesize that amino acid substitutions could explain why loggerhead Hb precipitates under normal physiologic conditions, forming Heinz bodies. The identification of inclusion bodies in loggerhead erythrocytes allow us to better understand the haematological characteristics and the physiology of these ancient reptiles, thus aiding efforts to conserve such an endangered species.

  13. Body size and body composition effects on heat loss from the hands during severe cold exposure.

    Payne, Stephanie; Macintosh, Alison; Stock, Jay

    2018-02-11

    This study investigated the influence of body size and composition on maintaining hand temperature during severe cold exposure. The hand's high surface area-to-volume ratio predisposes the hand to heat loss, increasing the risk of cold injury and even hypothermia, which are major selective pressures in cold environments. While vasoregulation may reduce heat loss from the hand, the effect of body form, tissue thermogenesis, and body insulation on heat loss is unknown. Thermal imaging was used to determine heat loss during a 3-min ice-water hand immersion test carried out on 114 volunteers (female = 63, male = 51). Established anthropometric measures were used to quantify body size, and bioelectrical impedance analysis determined skeletal muscle and fat mass. Skeletal muscle mass relative to body mass was a highly significant predictor of heat loss, while body mass, fat mass, and stature were not. Body composition and body size had little to no significant influence during rewarming after immersion. The thermogenic properties of muscle mass support maintenance of hand temperature during severe cold exposure. The findings here suggest that muscular individuals are less susceptible to heat loss and cold injury, and may be better at manual tasks in cold conditions than nonmuscular individuals. © 2018 Wiley Periodicals, Inc.

  20. Introduction: Minds, Bodies, Machines

    Directory of Open Access Journals (Sweden)

    2008-10-01

    Full Text Available This issue of 19 brings together a selection of essays from an interdisciplinary conference on 'Minds, Bodies, Machines' convened last year by Birkbeck's Centre for Nineteenth-Century Studies, University of London, in partnership with the English programme, University of Melbourne and software developers Constraint Technologies International (CTI. The conference explored the relationship between minds, bodies and machines in the long nineteenth century, with a view to understanding the history of our technology-driven, post-human visions. It is in the nineteenth century that the relationship between the human and the machine under post-industrial capitalism becomes a pervasive theme. From Blake on the mills of the mind by which we are enslaved, to Carlyle's and Arnold's denunciation of the machinery of modern life, from Dickens's sooty fictional locomotive Mr Pancks, who 'snorted and sniffed and puffed and blew, like a little labouring steam-engine', and 'shot out […]cinders of principles, as if it were done by mechanical revolvency', to the alienated historical body of the late-nineteenth-century factory worker under Taylorization, whose movements and gestures were timed, regulated and rationalised to maximize efficiency; we find a cultural preoccupation with the mechanisation of the nineteenth-century human body that uncannily resonates with modern dreams and anxieties around technologies of the human.

  7. Being Better Bodies.

    Reynolds, Joel Michael

    2017-11-01

    Bioethics has an uneasy relationship with embodiment. Only with vigilance does knowledge of the body as it is lived counterbalance the momentous inertia of knowledge of the body as an object brought about by modern medical sciences. As a field tethered to detached, technical ways of knowing the world, bioethics must toil to treat the body as more than mere material and machine. To be more is, among other things, to be social-to live in the thickets of interdependence and the institutions and practices we build, hone, and defend to facilitate it. I take this tension to define the ultimate stakes of Melinda Hall's The Bioethics of Enhancement: Transhumanism, Disability, and Biopolitics. Hall homes in on transhumanism, the idea that we should embrace technology to vault beyond current human limitations. Yet the work serves as a reminder for all bioethicists and philosophers of how easily one can be led astray by otherwise irreproachable values when they are disconnected from the conditions and realities of human life, including being irremediably interdependent embodied beings. Put more acerbically, the book is a reminder of how thinking goes wrong when divorced from the principal sources out of which human appraisals emerge: our fleshy, messy, social bodies. © 2017 The Hastings Center.

  10. Biopower in the bodies

    Directory of Open Access Journals (Sweden)

    José Luis Tejeda

    2012-11-01

    Full Text Available Lately, the studies of biopolitics and biopower have risen significantly. It is an old issue, which is present in Greek philosophy and in its reality. It is the old argument of the relationship and the intrusion of politics in the life and the overcoming of the state of nature. The reality of biopolitics is reflected in the dimension that technology acquires and in the siege of the global powers against democracy. The human body as an external and visible entity resists all kinds of interventions and fastenings aimed at the individualization and establishment of a totalitarian reality. Tanatopolitics and Biopolitics are interlaced to manage life and death in a chilling reality where technique introduces the artifice beyond the natural. The human body as a borderline area between the natural and the artificial expresses the scopes of post-humanism. A more balanced physical culture could help to curb the widespread dehumanization, which reduces and degrades the body at the same time, while the powers submit, discriminate, and intervene in the more and more docile bodies.

    2016-06-01

    Full Text Available This paper presents the results of an ethnographic research conducted in a bodybuilding gym where the author was working out. The analysis focuses on those who, according to the data gathered through participant observation, are identified as “real bodybuilders” namely: those who put their “ideal body” reference as a totalizing element of their identity. The aim of the research is to show how such individuals, once they have chosen an ideal body model – a model which is not hegemonic within society as whole – use it as a frame for almost all their cognitive representations and social interactions (gender, leadership, rituals, world classification and so on. It is mainly the body to provide a means of identification to this competitive subculture which is quite cohesive in terms of lifestyles and it also provides a means of individuation through its particular construction as well as presumed authority in terms of expertise readable as a form of power/knowledge.

  1. Soft Tissue Foreign Body: Utility of High Resolution Ultrasonography

    Reddy, Harish; Ibrahim, Jebin; Haritha, CH; Shah, Rushit Sandeep

    2017-01-01

    Introduction Minor percentage of wooden foreign bodies is radio-opaque. High Resolution Ultrasonography (HRUSG) though existing is sparsely used as a primary imaging modality for diagnosis and localization of retained foreign body. Aim To evaluate the diagnostic accuracy of High Resolution Ultrasonography (HRUSG) in diagnoses and localization of retained foreign body. Materials and Methods A prospective study with registered 46 patients with history of foreign body injury which were initially imaged with conventional radiography was enrolled. Later patients were subjected for high resolution USG of the diseased part with a linear transducer. Surface marking was done for all subjects to assist the surgical exploration. Ultrasound findings were correlated with surgical exploration and histopathological findings. Results Out of 46 patients, forty one showed foreign body with foreign body inflammatory reaction in the form of abscess and/or granulation tissue on high resolution ultrasonography. No foreign body was detected in five patients but they showed focal hypoechogenicity which represented abscess and/or haematoma. On surgical exploration, two out of 41 patients did not reveal foreign body where as rest were found to have foreign body with foreign body inflammatory reaction. Sensitivity and negative predictive value of the current study is 100%. Conclusion High resolution USG is not only an efficient modality in diagnosing and localizing the foreign body in soft tissue, but can also be utilized for guiding the foreign body removal.

  3. Body maps on the human genome.

    Cherniak, Christopher; Rodriguez-Esteban, Raul

    2013-12-20

    Chromosomes have territories, or preferred locales, in the cell nucleus. When these sites are taken into account, some large-scale structure of the human genome emerges. The synoptic picture is that genes highly expressed in particular topologically compact tissues are not randomly distributed on the genome. Rather, such tissue-specific genes tend to map somatotopically onto the complete chromosome set. They seem to form a "genome homunculus": a multi-dimensional, genome-wide body representation extending across chromosome territories of the entire spermcell nucleus. The antero-posterior axis of the body significantly corresponds to the head-tail axis of the nucleus, and the dorso-ventral body axis to the central-peripheral nucleus axis. This large-scale genomic structure includes thousands of genes. One rationale for a homuncular genome structure would be to minimize connection costs in genetic networks. Somatotopic maps in cerebral cortex have been reported for over a century.

  4. Body image, eating disorders, and the media.

    Science.gov (United States)

    Hogan, Marjorie J; Strasburger, Victor C

    2008-12-01

    Adolescence is a time of tremendous change in physical appearance. Many adolescents report dissatisfaction with their body shape and size. Forming one's body image is a complex process, influenced by family, peers, and media messages. Increasing evidence shows that the combination of ubiquitous ads for foods and emphasis on female beauty and thinness in both advertising and programming leads to confusion and dissatisfaction for many young people. Sociocultural factors, specifically media exposure, play an important role in the development of disordered body image. Of significant concern, studies have revealed a link between media exposure and the likelihood of having symptoms of disordered eating or a frank eating disorder. Pediatricians and other adults must work to promote media education and make media healthier for young people. More research is needed to identify the most vulnerable children and adolescents.

    1990-07-01

    Numerical simulations of the last stage of terrestrial planetary formation are performed using an N-body code similar to that of Lecar and Aarseth (1986). An improved treatment of collisions has been applied, which allows fragmentation and cratering, as well as accretion. Initial models consist of 200 bodies of total mass 2.3 x 10 to the 28th g, distributed in a two-dimensional ring of size 1 AU with initial circular orbits about the sun. Planetary embryos begin to form by accretion in the early stages when the relative velocities are small. Eventually, a small number of massive embryos emerge, and subsequently accrete nearly all the fragments. Final configurations of three different models yield four principal bodies with moderate eccentricities on a time-scale of 500,000 yr.

    Energy Technology Data Exchange (ETDEWEB)

    Affonso, Regina

    2000-07-01

    Different vector elements, that can determine a high expression level of a form of human prolactin (taghPrl) in bacterial cytoplasm, were studied. Expression conditions were first optimized for a reference vector, which was used to transform different strains of E. coli: HB2151, RRI and RB791. The highest expression level (113 {+-}16 {mu}g/mL.A{sub 600}) was obtained in HB2151, after activation with only 0.1 mM IPTG. At this point the influence of the transcription terminator (g32 from bacteriophage T4), of the translation enhancer (g10 from bacteriophage T7), of the promoter ({lambda}P{sub L} or tac) and of the antibiotic resistance gene (amp{sup r} or kan{sup r}) were studied. The first three elements did not show any significant influence, at least in our systems. On the contrary, the analysis of the influence of amp{sup r} and kan{sup r} genes showed, unexpectedly, that the presence of the last one provides an approximately 5-fold higher expression for taghPrl in E. coli cytoplasm. Finally, an appropriate extraction, solubilization, renaturation and purification process, able to provide a monomeric form of taghPrl, was studied. A method utilizing urea and mercaptoethanol as solubilizing agents and a dialysis as a renaturation procedure, provided with some modifications, one of the highest yields ever reported in the literature: 35.4 {+-} 4.5% of total recovery. Moreover, the biological activity of the taghPrl obtained, when tested in the Nb2 cell proliferation assay, was of the same order of that shown by the International Standard of human prolactin of pituitary origin. These data show that the cytoplasmic expression system here described, which can provide an expression efficiency 50-100 - fold higher than the periplasmic expression, can represent a valid alternative for the production of this and of other hormones of pharmaceutical interest and grade.

    We consider the stirring of an inviscid fluid caused by the locomotion of bodies through it. The swimmers are approximated by non-interacting cylinders or spheres moving steadily along straight lines. We find the displacement of fluid particles caused by the nearby passage of a swimmer as a function of an impact parameter. We use this to compute the effective diffusion coefficient from the random walk of a fluid particle under the influence of a distribution of swimming bodies. We compare with the results of simulations. For typical sizes, densities and swimming velocities of schools of krill, the effective diffusivity in this model is five times the thermal diffusivity. However, we estimate that viscosity increases this value by two orders of magnitude.

    2012-06-01

    Full Text Available Since Classical times in Western thought Nature and Culture have been conceptualized as dualistic and belonging to separate and distinct domains of reference. Philosophers, scientists and lawyers throughout the ages have considered women’s destiny as being rooted passively in Nature, which was seen as repetitive and predictable. In a similar way they considered that sexuality and gender relations were unchangeable and based on biological elements that were immutable. Only the male could be active and creative at home in the realm of Logos. In Gender Studies this ancient dichotomy has been radically challenged. Numerous historical and cultural contexts have been examined in which both secular and religious powers have imposed determined prohibitions and patterns of behaviour concerning the physical body of men, women and children and the way in which their physicality should be expressed or repressed. This issue presents studies that consider the sphere of the body in its cultural and historical dimension.

    Obesity in humans might increase the risk of periodontitis. The aim of the present study was to examine the relationship between body composition of males and their periodontal status. AS total of 150 males (aged 30-60) were selected: 31 were periodontally healthy, 45 had gingivitis, 39 had initial periodontitis, and 35 suffered from established periodontitis. BMI (body mass index), WC (waist circumference), and body composition parameters (consisting of body water, body fat, and skeletal muscle and bone mass) were measured. After adjusting for age, history of diabetes, smoking, physical activity status, and socioeconomic status, statistically significant correlations were found between periodontitis and BMI, WC, and body composition. There was only a statistically significant difference between the periodontal health and established periodontitis; that is, periodontal disease in mild forms (gingivitis) and initial periodontitis do not influence these variables (BMI, WC, and body composition parameters) and only the severe form of the disease influences the variables. These data suggest that there is a considerable association between severe forms of periodontal disease in males and their body composition, but this preliminary finding needs to be confirmed in more extensive studies.

    In our rapidly changing world, we are often encouraged to treat our bodies as objects of constant improvement by means of various facilities and innovations. As part of this "Promethean tendency," the present-day alliance between medicine and technology has opened up a new perspective on the ill and disabled body, by providing access to sophisticated prosthetics that are increasingly seen as ideal remedies. These devices allow patients to benefit from previously unimaginable treatments and inestimable scientific advances, yet they also create new forms of dependency that go beyond simply forming a habit. They are part of a complex process which results in the construction of a body full of paradoxes and whose effects go beyond the subject's image construction. Based on the case of Mathilde, a little girl with a partial arm agenesis, the author traces some elements of the psychic process of constructing a body: from a congenital malformation towards a body "supplemented" by a prosthesis.

    In this paper we continue our systematic study of form factors of half-BPS operators in mathcal{N} = 4 super Yang-Mills. In particular, we extend various on-shell techniques known for amplitudes to the case of form factors, including MHV rules, recursion relations, unitarity and dual MHV rules. As an application, we present the solution of the recursion relation for split-helicity form factors. We then consider form factors of the stress-tensor multiplet operator and of its chiral truncation, and write down supersymmetric Ward identities using chiral as well as non-chiral superspace formalisms. This allows us to obtain compact formulae for families of form factors, such as the maximally non-MHV case. Finally we generalise dual MHV rules in dual momentum space to form factors.

    Cyrol, Anton K.; Mitter, Mario; Strodthoff, Nils

    2017-10-01

    We present FormTracer, a high-performance, general purpose, easy-to-use Mathematica tracing package which uses FORM. It supports arbitrary space and spinor dimensions as well as an arbitrary number of simple compact Lie groups. While keeping the usability of the Mathematica interface, it relies on the efficiency of FORM. An additional performance gain is achieved by a decomposition algorithm that avoids redundant traces in the product tensors spaces. FormTracer supports a wide range of syntaxes which endows it with a high flexibility. Mathematica notebooks that automatically install the package and guide the user through performing standard traces in space-time, spinor and gauge-group spaces are provided. Program Files doi:http://dx.doi.org/10.17632/7rd29h4p3m.1 Licensing provisions: GPLv3 Programming language: Mathematica and FORM Nature of problem: Efficiently compute traces of large expressions Solution method: The expression to be traced is decomposed into its subspaces by a recursive Mathematica expansion algorithm. The result is subsequently translated to a FORM script that takes the traces. After FORM is executed, the final result is either imported into Mathematica or exported as optimized C/C++/Fortran code. Unusual features: The outstanding features of FormTracer are the simple interface, the capability to efficiently handle an arbitrary number of Lie groups in addition to Dirac and Lorentz tensors, and a customizable input-syntax.

    The notion of subject in human language has a privileged status relative to other arguments. This special status is manifested in the behavior of subjects at the morphological, syntactic, semantic and discourse levels. Here we bring evidence that subjects have privileged status at the lexical level as well, by analyzing lexicalization patterns of verbs in three different sign languages. Our analysis shows that the sublexical structure of iconic signs denoting state of affairs in these languages manifests an inherent pattern of form–meaning correspondence: the signer’s body consistently represents one argument of the verb, the subject. The hands, moving in relation to the body, represent all other components of the event – including all other arguments. This analysis shows that sign languages provide novel evidence in support of the centrality of the notion of subject in human language. It also solves a typological puzzle about the apparent primacy of object in sign language verb agreement, a primacy not usually found in spoken languages, in which subject agreement ranks higher. Our analysis suggests that the subject argument is represented by the body and is part of the lexical structure of the verb. Because it is always inherently represented in the structure of the sign, the subject is more basic than the object, and tolerates the omission of agreement morphology. PMID:23066169

  7. Fashion, Bodies, and Objects

    Full Text Available This essay is based on the assumption that the body has undergone a process of fragmentation that started with "modern" art and commodity fetishism that is being amplified today by an increasingly fetishistic high fashion industry itself relayed by music videos and a gigantic pornography industry. This article begins with a discussion of fetishism and objectification as they appear in high fashion shows where underwear becomes wear (turning the inside into the outside, thus expanding (or dissolving the traditional notion of pornography because they are both reported in comparable terms by mainstream magazines such as Femmes and less conventional publications such as Penthouse . A comparable phenomenon takes place in the novels of Hervé Guibert where internal organs (that is the inside become literary characters (as "outside" through medical imagery. Finally, an issue of the French New Look magazine is analyzed because it features a high fashion collection next to a pictorial/essay on Issei Sagawa, a.k.a. "the Japanese Cannibal." Here again, the objectification of the dismembered body is taken a step further both by designer Jean-Paul Gaultier and Sagawa. It thus appears that the human body is nowadays being totally invested by commodity fetishism, rendering gender difference obsolete and opening a new space that so far has no name, and announces the final merging of high fashion, literature, pornography, and music videos.

  10. Structure and applications of point form relativistic quantum mechanics

    International Nuclear Information System (INIS)

    Klink, W.H.

    2003-01-01

    The framework of point form relativistic quantum mechanics is used to construct mass and current operators for hadronic systems with finite degree of freedom. For the point form all of the interactions are in the four-momentum operator and, since Lorentz transformations are kinematic, the theory is manifestly covariant. In the Bakamjian-Thomas version of the point form the four-momentum operator is written as a product of the four-velocity operator and mass operator, where the mass operator is the sum of free and interacting mass operators. Interacting mass operators can be constructed from vertices, matrix elements of local field operators evaluated at the space-time point zero, where the states are eigenstates of the four-velocity. Applications include the study of the spectra and widths of vector mesons, viewed as bound states of quark-antiquark pairs. Besides mass operators, current operators are needed to compute form factors. Form factors are matrix elements of current operators on mass operator eigenstates and are often calculated with one-body current operators (in the point form this is called the point form spectator approximation); but in a properly relativistic theory there must also be many-body current operators. Minimal currents needed to satisfy current conservation in the presence of hadronic interactions (called dynamically determined currents) are shown to be easily calculated in the point form.

    A broad program measuring parity-violation in electron-nuclear scattering has now provided a large set of precision data on the weak-neutral-current form-factors of the proton. Under comparison with well-measured electromagnetic nucleon form-factors, these measurements reveal the role of the strange quark sea on the low-energy interactions of the proton through the strange-quark-flavor vector form-factors. This review will describe the experimental program and the implications of the global data for the strange-quark vector form-factors. We present here a new fit to the world data.

    Conventional dosage forms such as tablets, capsules and syrups are prescribed in the normal course of practice. However, concerns about patient preferences and market demands have given rise to the exploration of novel unconventional dosage forms. Among these, confectionery-based dose forms have strong potential to overcome compliance problems. This report will review the availability of these unconventional dose forms used in treating the oral cavity and for systemic drug delivery, with a focus on medicated chewing gums, medicated lollipops, and oral bioadhesive devices. The aim is to stimulate increased interest in the opportunities for innovative new products that are available to formulators in this field, particularly for atypical patient populations.

    2016-02-01

    Full Text Available The study was conducted by method of light scattering of laser emission. The influence of the form field, mutual influence of mental informational and form torsional fields as well as the following exposure of water samples in the form field after the cease of informational influence on water structure were examined. Paper forms of a pyramid, a cylinder, and a prism were used. The experimental findings show that mechanism of mutual influence on water structure of the form and informational torsional fields depended on the initial conditions of spin restructuring process – the configuration of a form, the type of the form field (internal and external ones, and the initial water structure. The influence of the form field on informational aftereffect was determined, the character of which was defined by ratio of intensities of torsional form field and an informational soliton. The phenomenon of the abnormally large amplification of the informational aftereffect in the internal field of a pyramid demonstrating the attributes of positive reverse connection between the informational soliton and torsional field of water structure and selection of generated cluster sizes were discovered.

  18. Interconnected cavernous structure of bacterial fruiting bodies.

    Directory of Open Access Journals (Sweden)

    Cameron W Harvey

    Full Text Available The formation of spore-filled fruiting bodies by myxobacteria is a fascinating case of multicellular self-organization by bacteria. The organization of Myxococcus xanthus into fruiting bodies has long been studied not only as an important example of collective motion of bacteria, but also as a simplified model for developmental morphogenesis. Sporulation within the nascent fruiting body requires signaling between moving cells in order that the rod-shaped self-propelled cells differentiate into spores at the appropriate time. Probing the three-dimensional structure of myxobacteria fruiting bodies has previously presented a challenge due to limitations of different imaging methods. A new technique using Infrared Optical Coherence Tomography (OCT revealed previously unknown details of the internal structure of M. xanthus fruiting bodies consisting of interconnected pockets of relative high and low spore density regions. To make sense of the experimentally observed structure, modeling and computer simulations were used to test a hypothesized mechanism that could produce high-density pockets of spores. The mechanism consists of self-propelled cells aligning with each other and signaling by end-to-end contact to coordinate the process of differentiation resulting in a pattern of clusters observed in the experiment. The integration of novel OCT experimental techniques with computational simulations can provide new insight into the mechanisms that can give rise to the pattern formation seen in other biological systems such as dictyostelids, social amoeba known to form multicellular aggregates observed as slugs under starvation conditions.

  19. Dynamic representations of human body movement.

    Science.gov (United States)

    Kourtzi, Z; Shiffrar, M

    1999-01-01

    Psychophysical and neurophysiological studies suggest that human body motions can be readily recognized. Human bodies are highly articulated and can move in a nonrigid manner. As a result, we perceive highly dissimilar views of the human form in motion. How does the visual system integrate multiple views of a human body in motion so that we can perceive human movement as a continuous event? The results of a set of priming experiments suggest that motion can readily facilitate the linkage of different views of a moving human. Positive priming was found for novel views of a human body that fell within the path of human movement. However, no priming was observed for novel views outside the path of motion. Furthermore, priming was restricted to those views that satisfied the biomechanical constraints of human movement. These results suggest that visual representation of human movement may be based upon the movement limitations of the human body and may reflect a dynamic interaction of motion and object-recognition processes.

  20. Implicit Beliefs about Ideal Body Image Predict Body Image Dissatisfaction

    Directory of Open Access Journals (Sweden)

    Niclas eHeider

    2015-10-01

    Full Text Available We examined whether implicit measures of actual and ideal body image can be used to predict body dissatisfaction in young female adults. Participants completed two Implicit Relational Assessment Procedures (IRAPs to examine their implicit beliefs concerning actual (e.g., I am thin and desired ideal body image (e.g., I want to be thin. Body dissatisfaction was examined via self-report questionnaires and rating scales. As expected, differences in body dissatisfaction exerted a differential influence on the two IRAP scores. Specifically, the implicit belief that one is thin was lower in participants who exhibited a high degree of body dissatisfaction than in participants who exhibited a low degree of body dissatisfaction. In contrast, the implicit desire to be thin (i.e., thin ideal body image was stronger in participants who exhibited a high level of body dissatisfaction than in participants who were less dissatisfied with their body. Adding further weight to the idea that both IRAP measures captured different underlying constructs, we also observed that they correlated differently with body mass index, explicit body dissatisfaction, and explicit measures of actual and ideal body image. More generally, these findings underscore the advantage of using implicit measures that incorporate relational information relative to implicit measures that allow for an assessment of associative relations only.

    Science.gov (United States)

    Monjaraz Fuentes, Paulina; Rojas Hernández, María Del Carmen; Santasilia, Stefano; Monjaraz Fuentes, Fernanda

    2017-12-01

    The aim of this manuscript is to highlight that from the phenomenology and psychoanalysis point of view, the meaning of the notion of the body is different from the medical biologicist discourse. In psychoanalysis, the body is an erogenized body. It is constituted as an object for another self. Similarly, in phenomenology, the body is an own body in first instance. It is the body of a self, rather than a living body and a material body. Both positions enable us to understand how this conceptualization of the body is essential in any human field. Especially in the clinic, the position of the subject before the other will lead to a specific form of intervention. From this understanding of the human body, both phenomenology and psychoanalysis confirm that the biologicist understanding of the body, presumed by all psychological and medical practices, is insufficient.

  5. Modern medicine and the "uncertain body": from corporeality to hyperreality?

    Science.gov (United States)

    Williams, S J

    1997-10-01

    This paper (re)considers the role of medical technology at three interrelated levels: first, the extent to which medical technology renders our bodies increasingly "uncertain" at the turn of the century; second, the analytical purchase which the notion of the (medical) cyborg provides regarding contemporary forms of human embodiment; and finally, at a broader level, the issues this raises in relation to a (late) modernist or postmodernist reading of contemporary medical practice. Key themes here include the plastic body, the bionic body, communal/interchangeable bodies, (genetically) engineered/ chosen bodies, and virtual bodies. The paper concludes with a critical appraisal of these themes and issues, arguing for a late modernist position on medical technology as both a positive and negative rationalising force, and a "life political agenda" in which the "all-too-human" quality of human nature is seen as inviolable.

  6. Differentiation history of small bodies in the solar system: the howardite and mesosiderite meteorite parent bodies

    International Nuclear Information System (INIS)

    Mittlefehldt, D.W.

    1978-01-01

    Mesosiderites and howardites are regolith samples of differentiated asteroids. Instrumental neutron activation analysis (INAA) data on whole rock howardites and mesosiderite silicates show that the composition of howardites and mesosiderites are similar, and intermediate between those of eucrites and diogenites. The mesosiderites Mincy, Lowicz and Veramin show an enrichment in light REE and have an REE pattern that is qualitatively similar to that in terrestrial basalts thought to have been formed by small degrees of partial melting. Attempts to model the REE abundances in these mesosiderites indicates that they most likely formed by approx. 2 to 4% partial melting of a source containing low abundances of the rare earths. Since numerous properties separate mesosiderite silicates from howardites, it is clear that they are not samples of a well-mixed regolith from a single parent body. If regolith stirring is efficient on small parent bodies, then mesosiderites and howardites originated on separate parent bodies. Rare earth element patterns give evidence for remelting and fractional crystallization of preexisting cumulates and sequential melting episodes. The mesosiderites appear to contain a slightly greater abundance of diogenite-like material and certainly contain a greater abundance of large olivine clasts. These observations suggest that the mesosiderite parent body crust was more complexly fractionated than the howardite parent body crust. The latter appears to have been dominated by quenched basalt flows

    The wingless, lifting body aircraft sitting on Rogers Dry Lake at what is now NASA's Dryden Flight Research Center, Edwards, California, from left to right are the X-24A, M2-F3 and the HL-10.The lifting body aircraft studied the feasibility of maneuvering and landing an aerodynamic craft designed for reentry from space. These lifting bodies were air launched by a B-52 mother ship, then flew powered by their own rocket engines before making an unpowered approach and landing. They helped validate the concept that a space shuttle could make accurate landings without power. The X-24A flew from April 17, 1969 to June 4, 1971. The M2-F3 flew from June 2, 1970 until December 22, 1972. The HL-10 flew from December 22, 1966 until July 17, 1970, and logged the highest and fastest records in the lifting body program. The X-24 was one of a group of lifting bodies flown by the NASA Flight Research Center (FRC-now Dryden Flight Research Center), Edwards, California, in a joint program with the U.S. Air Force at Edwards Air Force Base from 1963 to 1975. The lifting bodies were used to demonstrate the ability of pilots to maneuver and safely land wingless vehicles designed to fly back to Earth from space and be landed like an airplane at a predetermined site. Lifting bodies' aerodynamic lift, essential to flight in the atmosphere, was obtained from their shape. The addition of fins and control surfaces allowed the pilots to stabilize and control the vehicles and regulate their flight paths. Built by Martin Aircraft Company, Maryland, for the U.S. Air Force, the X-24A was a bulbous vehicle shaped like a teardrop with three vertical fins at the rear for directional control. It weighed 6,270 pounds, was 24.5 feet long and 11.5 feet wide (measuring just the fuselage, not the distance between the tips of the outboard fins). Its first unpowered glide flight was on April 17, 1969, with Air Force Maj. Jerauld Gentry at the controls. Gentry also piloted its first powered flight on March 19

    Rayburn, W F

    1990-03-01

    Recording fetal activity serves as an indirect measure of central nervous system integrity and function. The coordination of whole body movement, which requires complex neurologic control, is likely similar to that of the newborn infant. Short-term observations of the fetus are best performed using real-time ultrasound imaging. Monitoring fetal motion has been shown to be clinically worthwhile in predicting impending death or compromise, especially when placental insufficiency is longstanding. The presence of a vigorous fetus is reassuring. Perceived inactivity requires a reassessment of any underlying antepartum complication and a more precise evaluation by fetal heart rate testing or real-time ultrasonography before delivery is contemplated.

    In the present chapter, that is part of a more comprehensive work performed by the Argentine Consortium for Dementia Study - Consortium Argentino para el Estudio de la Demencia (CAED), we describe the most frequent forms of beginning for the four more prevalent types of dementia: Alzheimer's disease, dementia with Lewy bodies, vascular dementia and frontotemporal dementia). Despite this, it must be kept in mind, that frequently the clinical presentation is not typical and the diagnostic impression at the disease's beginning is controversial comparing it with the etiological diagnosis reached when the dementia is definitively installed. This issue must be considered when the initial impression is given to the patient and/or relatives. It must be clarified, in this instance, that this impression is based in statistical data of ways of presentation, but the definitive diagnosis could be different according to the dementia evolution.

  4. Barthes's Body of Knowledge

    Full Text Available Roland Barthes invites a reading of his own texts in terms of the same methodologies he employs in his criticism. The «Biographeme»—those few details, preferences, inflections—which Barthes identified in his favorite authors, may be sought in Barthes as well. Barthes's biographeme, for me, consists of a glutinous effect associated with the organs of the mouth and throat as presented in several images, some of which belong to his tutor texts (Poe and Réquichot. An analysis of this biographeme reveals Barthes's strategy for disseminating the subject of knowledge—the author's fantasmatic body—through the signifiers of writing, fusing the heterogeneous singularities of the knower and the object of study. The metaphorical discourse that results opposes normal academic preoccupations in favor of knowledge of/as desire. Knowledge itself in Barthes becomes a second order signifier caught up in a catachretic process for naming the real. Barthes's procedure for exploring the real affectively, in terms of the body as it is defined in psychoanalysis, imposes on the reader a similar obligation to bring his or her own body into play in the learning experience. Barthes offers a model for a new genre of academic writing, combining science with autobiography, that has important implications for teaching and research in the humanities and social sciences.

  5. Body shape preferences: associations with rater body shape and sociosexuality.

    Directory of Open Access Journals (Sweden)

    Michael E Price

    Full Text Available There is accumulating evidence of condition-dependent mate choice in many species, that is, individual preferences varying in strength according to the condition of the chooser. In humans, for example, people with more attractive faces/bodies, and who are higher in sociosexuality, exhibit stronger preferences for attractive traits in opposite-sex faces/bodies. However, previous studies have tended to use only relatively simple, isolated measures of rater attractiveness. Here we use 3D body scanning technology to examine associations between strength of rater preferences for attractive traits in opposite-sex bodies, and raters' body shape, self-perceived attractiveness, and sociosexuality. For 118 raters and 80 stimuli models, we used a 3D scanner to extract body measurements associated with attractiveness (male waist-chest ratio [WCR], female waist-hip ratio [WHR], and volume-height index [VHI] in both sexes and also measured rater self-perceived attractiveness and sociosexuality. As expected, WHR and VHI were important predictors of female body attractiveness, while WCR and VHI were important predictors of male body attractiveness. Results indicated that male rater sociosexuality scores were positively associated with strength of preference for attractive (low VHI and attractive (low WHR in female bodies. Moreover, male rater self-perceived attractiveness was positively associated with strength of preference for low VHI in female bodies. The only evidence of condition-dependent preferences in females was a positive association between attractive VHI in female raters and preferences for attractive (low WCR in male bodies. No other significant associations were observed in either sex between aspects of rater body shape and strength of preferences for attractive opposite-sex body traits. These results suggest that among male raters, rater self-perceived attractiveness and sociosexuality are important predictors of preference strength for

    Full Text Available Starting from a very general trace-form entropy, we introduce a pair of algebraic structures endowed by a generalized sum and a generalized product. These algebras form, respectively, two Abelian fields in the realm of the complex numbers isomorphic each other. We specify our results to several entropic forms related to distributions recurrently observed in social, economical, biological and physical systems including the stretched exponential, the power-law and the interpolating Bosons-Fermions distributions. Some potential applications in the study of complex systems are advanced.

    The field of plutonium disposition is varied and of much importance, since the Department of Energy has decided on the hybrid option for disposing of the weapons materials. This consists of either placing the Pu into mixed oxide fuel for reactors or placing the material into a stable waste form such as glass. The waste form used for Pu disposition should exhibit certain qualities: (1) provide for a suitable deterrent to guard against proliferation; (2) be of minimal volume, i.e., maximize the loading; and (3) be reasonably durable under repository-like conditions. This paper will discuss several Pu waste forms that display promising characteristics

  14. Machine-learning methods in the classification of water bodies

    Full Text Available Amphibian species have been considered as useful ecological indicators. They are used as indicators of environmental contamination, ecosystem health and habitat quality., Amphibian species are sensitive to changes in the aquatic environment and therefore, may form the basis for the classification of water bodies. Water bodies in which there are a large number of amphibian species are especially valuable even if they are located in urban areas. The automation of the classification process allows for a faster evaluation of the presence of amphibian species in the water bodies. Three machine-learning methods (artificial neural networks, decision trees and the k-nearest neighbours algorithm have been used to classify water bodies in Chorzów – one of 19 cities in the Upper Silesia Agglomeration. In this case, classification is a supervised data mining method consisting of several stages such as building the model, the testing phase and the prediction. Seven natural and anthropogenic features of water bodies (e.g. the type of water body, aquatic plants, the purpose of the water body (destination, position of the water body in relation to any possible buildings, condition of the water body, the degree of littering, the shore type and fishing activities have been taken into account in the classification. The data set used in this study involved information about 71 different water bodies and 9 amphibian species living in them. The results showed that the best average classification accuracy was obtained with the multilayer perceptron neural network.

  15. 'Every bone of my body:' domestic violence and the diagnostic body.

    Science.gov (United States)

    Sweet, Paige L

    2014-12-01

    Diagnostic categories for domestic violence have shifted over time, transforming from a disorder of psychological passivity and acute injury into a chronic and somatically invasive condition. This paper links these changing diagnoses to constructions of the abused body and to victim-blaming narratives. Based on an analysis of medical journal articles, this research identifies two logics that undergird domestic violence diagnoses, the body, and victim-blaming: 1) the logic of injury (1970s-1980s); and 2) the logic of health (late 1980s-present). The logic of injury is associated with overt victim-blaming, a temporally bounded and injured body, and psychological passivity. Once the feminist anti-violence movement gained mainstream credibility, however, the logic of injury fell out of favor as an explanation for domestic violence. What surfaced next was the logic of health, which is associated with chronic diagnoses and what the author calls a temporally extended body. The temporally extended body is flexible and layered, linking up past, present, and future states of disordered embodiment. The author suggests that, rather than ushering in hope and possibility via the logic of health's somatic flexibility, this abused body creates spaces into which new forms of blame and self-responsibility can take shape.

  16. Body dissatisfaction and attentional bias to thin bodies.

    Evidence for attentional biases to weight- and shape-related information in women with eating concerns is inconclusive. We investigated whether body dissatisfaction is associated with an attentional bias toward thin bodies using a modified dot probe task. In three studies, we found that undergraduate females were faster to discriminate the direction of an arrow cue when it appeared in the location previously occupied by a thin than a fat body. This attentional bias toward thin bodies was found using extreme stimuli (thin and fat bodies) presented for 500 ms (Experiment 1), extreme stimuli presented for 150 ms (Experiment 2), and less extreme stimuli that were equated for perceived extremity, presented for 150 ms (Experiment 3). When the stimuli were equated on perceptual extremity, the more dissatisfied a woman was with her body, and the larger her own BMI, the less of an attentional bias she showed toward thin bodies. Our results indicate that women have an attentional bias to thin bodies, which appears to be automatic. Contrary to prediction, this bias was weaker in women with greater BMI and body dissatisfaction. This result offers no support for the view that selective attention to thin bodies is causally related to body dissatisfaction.

  18. Positive geometries and canonical forms

    Recent years have seen a surprising connection between the physics of scattering amplitudes and a class of mathematical objects — the positive Grassmannian, positive loop Grassmannians, tree and loop Amplituhedra — which have been loosely referred to as "positive geometries". The connection between the geometry and physics is provided by a unique differential form canonically determined by the property of having logarithmic singularities (only) on all the boundaries of the space, with residues on each boundary given by the canonical form on that boundary. The structures seen in the physical setting of the Amplituhedron are both rigid and rich enough to motivate an investigation of the notions of "positive geometries" and their associated "canonical forms" as objects of study in their own right, in a more general mathematical setting. In this paper we take the first steps in this direction. We begin by giving a precise definition of positive geometries and canonical forms, and introduce two general methods for finding forms for more complicated positive geometries from simpler ones — via "triangulation" on the one hand, and "push-forward" maps between geometries on the other. We present numerous examples of positive geometries in projective spaces, Grassmannians, and toric, cluster and flag varieties, both for the simplest "simplex-like" geometries and the richer "polytope-like" ones. We also illustrate a number of strategies for computing canonical forms for large classes of positive geometries, ranging from a direct determination exploiting knowledge of zeros and poles, to the use of the general triangulation and push-forward methods, to the representation of the form as volume integrals over dual geometries and contour integrals over auxiliary spaces. These methods yield interesting representations for the canonical forms of wide classes of positive geometries, ranging from the simplest Amplituhedra to new expressions for the volume of arbitrary convex

  19. Forms of Approximate Radiation Transport

    CERN Document Server

    Brunner, G

    2002-01-01

    Photon radiation transport is described by the Boltzmann equation. Because this equation is difficult to solve, many different approximate forms have been implemented in computer codes. Several of the most common approximations are reviewed, and test problems illustrate the characteristics of each of the approximations. This document is designed as a tutorial so that code users can make an educated choice about which form of approximate radiation transport to use for their particular simulation.

  20. Origin and structure of Ubisch bodies in Pinus sylvestris

    John R. Rowley

    2014-01-01

    Full Text Available In Pinus sylvestris Ubisch bodies are produced repeatedly, and each crop is formed at a distinct phase in the secretory cycles of tapetal cells. While each production has a Ubisch body wall similar to the then current state of the exine with regard to thickening and ornamentation, the survivers of previous productions do not change. Examples of all the structurally different Ubisch body wall forms can be seen when terminally, at the time of pollen shedding, the relict Ubisch bodies become spatially concentrated on the minimal surface area of the senescent cells of the tapetum. In angiosperms after one or a few periods of initiation Ubisch bodies may remain in association with the surface of tapetal cells where the Ubisch body wall undergoes changes like those of the maturing pollen exine. We conclude that as a consequence of Ubisch body detachment from the plasma membrane of tapetal cells there is in Pinus sylvestris no updated information for modification of the wall and the Ubisch body wall remains static.
