    Full Text Available Tamarind seed polysaccharide (TSP, a natural polysaccharide extracted from tamarind seeds is used in the pharmaceutical, textile and food industries as a mucoadhesive polymer. This work aimed to extract TSP from tamarind seeds from three sources with two methods and characterized its physical and chemical properties. Kernel powder of tamarind seeds was slurried into a clear solution, set aside overnight and then centrifuged at 6000 rpm for 20 min to separate all foreign matter. The supernatant was separated and poured into excess 95% ethanol with continuous stirring. The precipitate obtained was collected and dried in the oven and then the dried TSP polymer was stored in a desiccator. The dried TSP was analyzed by 1H-NMR, FT-IR and XRD. The results showed TSP from tamarind seeds taken from paddy farmland (A, a waste from the export tamarind juice industry (B and the export tamarind powder industry(C gave yields of 31.55%, 26.95% and 17.30%, respectively, using method 1 and 11.15%, 53.65% and 54.65%, with method 2, respectively, but method 2 gave purer TSP than method 1. The FT-IR spectra displayed peaks at 3351.95 cm−1, 2920.76 cm−1, 1018.85 cm−1 and 555.16 cm−1. The 1H-NMR showed polysaccharide peaks between δ 3.50–4.20 ppm and XRD diagrams indicated their amorphous nature. Future works will focus on the quantitative analysis, biological activity and possible use of TSP as a drug delivery system.

    Agroforestry has a potential for sequestering as much carbon if not more than forests. Massive benefits can be channeled to small farmers and landless labourers through cultivation of Tamarind and other fast growing and fruit yielding trees. This paper describes a project in a semiarid area of south India. The aim is to upgrade dryland holdings of the member families through economically sound dry land horticulture, community woodlots, and planting of fast growing species along orchard and field boundaries. The small farmers invest massive labour inputs and project gives economic benefits to change their land use practices and improve environmental quality. This paper describes the planning processes of the project, hurdles in findings AIJ partners, current monitoring procedures and costs of C sequestration. This shows the project is economically viable on its own, but initially needed, and continues to need, carbon credit investment in order to spread rapidly across the geopolitical region covered by the organization. It argues that economic gains to small farmers and landless labourers are the most certain way of achieving massive biomass increase and soil carbon replenishment, and that multiple holistic benefits are achieved through this kind of project.

    Full Text Available Tamarind seed has been well-known as a perfect source of xyloglucan that has functional properties that can be applied in food products. In this research, the tamarind seeds were processed to be tamarind kernel powder (TKP and then it was added into the mango sauce as the stabilizer. The aim was to study the effects of using TKP as the stabilizer on the quality of mango sauce in comparison with the application of xanthan gum that is the common stabilizer of sauce. The mango sauce samples were determined their water activity, consistency, viscosity, color and sensorial quality. The result indicated that the addition of either TKP or xanthan gum at 0.25-0.5 %w/w could raise the viscosity and diminish consistency of mango sauce significantly whereas the water activity values were insignificantly different among samples. Furthermore, it appeared that the samples added with xanthan gum obtained less consistency values but more viscosity and sensorial scores than that of TKP. The color values of samples with TKP were significantly different from those with xanthan gum. The samples added xanthan gum became darker than the addition of TKP. Although the TKP caused the less preference in characteristics of mango sauce when comparing with xanthan gum, the better result might be achieved if TKP was processed to be more purified xyloglucan. The outcome of this work showed the possibility of utilizing the tamarind seed that is commonly by-product to be a valuable food additive for food industry.

    Reference is made to Dermott and Gold (Nature 267: 590 (1977)) who proposed a resonance model for the rings of Uranus. They assumed that the rings are composed of small particles librating about stable resonances determined by pairs of satellites, either Ariel and Titania or Ariel and Oberon. They dismissed as insignificant resonances involving 'tiny Miranda'. It is reported here that, by a wide margin, the strongest resonances are all associated with Miranda. It is also shown that the hypothesis that the rings are made up of librating particles, whilst original and ingenious, is incorrect. (author)

    In the present study, thiol-functionalization of tamarind seed polysaccharide was carried out by esterification with thioglycolic acid. Thiol-functionalization was confirmed by SH stretch in Fourier-transformed infra-red spectra at 2586 cm(-1). It was found to possess 104.5 mM of thiol groups per gram. The results of differential scanning calorimetry and X-ray diffraction study indicate increase in crystallinity. Polymer compacts of thiolated tamarind seed polysaccharide required 6.85-fold greater force to detach from the mucin coated membrane than that of tamarind seed polysaccharide. Comparative evaluation of Carbopol-based metronidazole gels containing thiolated tamarind seed polysaccharide with gels containing tamarind seed polysaccharide for mucoadhesive strength using chicken ileum by modified balance method revealed higher mucoadhesion of gels containing thiolated tamarind seed polysaccharide. Further, the gels containing tamarind seed polysaccharide and thiolated tamarind seed polysaccharide released the drug by Fickian-diffusion following the first-order and Higuchi's-square root release kinetics, respectively.

    2015-02-01

    Nineteen odour-active compounds were quantified in three black velvet tamarind fruit species. Calculation of the odour activity values (OAVs) of the odorants showed that differences in odour profiles of the tamarinds were mainly caused by linalool, limonene, 4-hydroxy-2,5-dimethyl-3(2H)-furanone, nonanal, and (Z)-3-hexenal. On the basis of their high OAVs, cis-linalool oxide (furanoid), geranyl acetone, and cinnamyl acetate were identified as other potent odorants in the three tamarinds. Sensory studies revealed very distinct aroma profiles, which are characteristic of these types of fruits. While the Dialiumguineense elicited floral, flowery, caramel-like notes, the other two species were dominated by leaf-like, caramel, and green notes. Copyright © 2014 Elsevier Ltd.

    Full Text Available Petroleum-contaminated soil contains various hazardous materials such as aromatic hydrocarbons and polycyclic aromatic hydrocarbons (PAHs. This study focused on PAHs since they are potentially toxic,mutagenic, and carcinogenic. Bioremediation of PAHs was carried out by adding tamarind leaf inoculums into petroleum-contaminated soil. Tamarind and other leguminous leaves have been reported to containedseveral PAH-degrading microorganisms. To minimize the amount of leaves added, the preparation of tamarind leaf inoculums was developed by incubating tamarind leaves with a sub-sample of contaminated soil for 49 days. After that, the efficiency of tamarind leaf inoculums was tested with two soil samplescollected from a navy dockyard and railway station in Samutprakarn and Bangkok, respectively. These soil samples had different levels of petroleum contamination. Bioaugmentation treatment was carried out bymixing contaminated soil with the inoculum at the ratio of 9:1. For navy dockyard soil, the concentration of phenanthrene was decreased gradually and reached the undetectable concentration within 56 days in theinoculated soil; meanwhile 70-80% of fluoranthene and pyrene were remained at the end of treatment. For railway station soil, which had lower petroleum contamination, PAH degradation was more rapid, forexample, the concentration of phenanthrene was below detection limit after 28 days. Besides PAHs, the amounts of several hydrocarbons were also reduced after treatment. At the same time, numerousphenanthrene-degrading bacteria, which were used as representatives of PAH degraders, could be observed in both inoculated soils. However, higher numbers of bacteria were found in railway station soil, whichcorresponded with the lower amount of PAHs and higher amount of soil nutrients. The results showed that inoculum prepared from tamarind leaves could be used to degrade PAHs as well as clean-up petroleum contaminated soil.

    Stress is a state that triggers change in normal physiology and recognized by human body and brain as an unfavorable event causing concern, worry or anxiety. It may vary from physical, metabolic, physiological or emotional often culminating into wide range of ailments that may range from common cold, decline in functional efficacy of body systems or even cancer. Skin is the largest tissue of the body and makes the first interface with the environment. Skin color and characteristics are highly influenced by environment stress. A variety of natural compounds have been used for anti-stress and disease preventive potentials in worldwide traditional home medicine systems. They have recently attracted attention in research laboratories to dissect their mode of action to promote safe and economic drug development. We have earlier identified anti-stress and anti-aging activities in Withania somnifera, Helicteres angustifolia and honeybee propolis using human cultured normal and cancer cells. In the present study, we explored the effect of tamarind seed extracts prepared in water or 95% ethanol. In cell-based assays, we found that the extracts were safe to use in viable cells (in the range of 0.01-1.0%, for at least 4 weeks). Consistently, molecular studies revealed no effect on the expression/activity of cancer promoting proteins. We recruited oxidative stress models, such as, hydrogen peroxide (H2O2), ultraviolet radiation (UV) and diacylglycerol 1-oleoyl-2-acetyl-sn-glycerol (OAG). Investigation on anti-stress potential of the extracts revealed that they do not offer remarkable protection against stress caused by either H2O2 or UV, however, significantly compromised OAG-induced melanogenesis. The preliminary data warrant further investigations on the active components and mechanism of action to develop useful natural compounds/extracts for manipulation of melanogenesis that plays important role in response of cells to UV and its consequences including DNA damage

Materials and Methods: In this study, 75 patients randomized in tamarind group (25 patients received daily 130 mg tamarind seed powder, paroxetine group (25 patients received daily 20 mg paroxetine, and placebo group (25 patients. Patients received the treatment regimen for 4 weeks. The primary outcome was intravaginal ejaculatory latency time (IELT. The secondary outcomes were PE diagnostic tool score, sexual function using International Index of Erectile Function (IIEF, and complications. Studied sexual functions include erectile function, orgasmic function, sexual desire, intercourse satisfaction, and overall satisfaction. Results: The mean of IELT in tamarind, paroxetine, and placebo groups at baseline was 35.2 ± 26.5, 38 ± 27.6, and 44 ± 34.9 s and at the end of study was 49.5 ± 48.2, 147.4 ± 209.6, and 46.9 ± 37.6 s, respectively, which in paroxetine group significantly increased compared to other groups. IIEF scores for orgasmic function and intercourse satisfaction for paroxetine after treatment significantly increased than that of other groups. The differences between tamarind and placebo groups for studied variables were not statistically significant. The mean of increases in IELT for tamarind, paroxetine, and placebo groups was 14.35 ± 34.3, 109.4 ± 213.4, and 2.9 ± 9.3 s, respectively, which in paroxetine group was significantly higher than other groups and in tamarind group was significantly higher than placebo. Conclusions: Paroxetine was significantly better than tamarind seed powder and placebo although side effect in paroxetine was more frequent. IELT significantly more increased in tamarind group compared to placebo.

    Tamarind (Tamarindus indica L) seed polysaccharide (TSP) is of great important due to its various biological activities. The present investigation was carried out to compare extraction yield, morphological characteristics, average molecular weights and antioxidant activities of TSP from gamma- and electron beam (EB)-irradiated tamarind kernel powder. The tamarind kernel powder was irradiated with 0, 5 and 10 kGy by gamma ray (GR) and electron beam, respectively. The extraction yield of TSP was increased significantly by EB and GR irradiation, but there was no significant difference between irradiation types. Morphological studies by scanning electron microscope showed that TSP from GR-irradiated tamarind seed had a fibrous structure, different from that of EB irradiated with a particle structures. The average molecular weight of TSP was decreased by the irradiation, and EB treatment degraded more severely than GR. Superoxide radical scavenging ability and total antioxidant capacity of EB-treated TSP showed higher than those of GR-treated TSP.

    Full Text Available Understanding the history of the amateur theater at the end of the XIXth century and the beginning of the XXth is possible, largely, because of the newspapers dedicated to the “theatrical affairs”. Such publications are important for the quantity and the diversity, revealing not only the place occupied by the theater in the capital, but also for the recognition of the press as a means of disclosure of plays, public education and opinion, artist projection, etc, not to mention personal affairs and requests, and the exchange of favors among managers and journalists. Even more, the press production of the dramatic amateurs clubs demonstrate the understanding of its role in the dissemination of ways to act and think beyond the stage and in the everyday life.

  7. Tiny Molybdenites Tell Diffusion Tales

    Stein, H. J.; Hannah, J. L.

    2014-12-01

    Diffusion invokes micron-scale exchange during crystal growth and dissolution in magma chambers on short time-scales. Fundamental to interpreting such data are assumptions on magma-fluid dynamics at all scales. Nevertheless, elemental diffusion profiles are used to estimate time scales for magma storage, eruption, and recharge. An underutilized timepiece to evaluate diffusion and 3D mobility of magmatic fluids is high-precision Re-Os dating of molybdenite. With spatially unique molybdenite samples from a young ore system (e.g., 1 Ma) and a double Os spike, analytical errors of 1-3 ka unambiguously separate events in time. Re-Os ages show that hydrous shallow magma chambers locally recharge and expel Cu-Mo-Au-silica as superimposed stockwork vein networks at time scales less than a few thousand years [1]. Re-Os ages provide diffusion rates controlled by a dynamic crystal mush, accumulation and expulsion of metalliferous fluid, and magma reorganization after explosive crystallization events. Importantly, this approach has broad application far from ore deposits. Here, we use Re-Os dating of molybdenite to assess time scales for generating and diffusing metals through the deep crust. To maximize opportunity for chemical diffusion, we use a continental-scale Sveconorwegian mylonite zone for the study area. A geologically constrained suite of molybdenite samples was acquired from quarry exposures. Molybdenite, previously unreported, is extremely scarce. Tiny but telling molybdenites include samples from like occurrences to assure geologic accuracy in Re-Os ages. Ages range from mid-Mesoproterozoic to mid-Neoproterozoic, and correspond to early metamorphic dehydration of a regionally widespread biotite-rich gneiss, localized melting of gneiss to form cm-m-scale K-feldspar ± quartz pods, development of vapor-rich, vuggy mm stringers that serve as volatile collection surfaces in felsic leucosomes, and low-angle (relative to foliation) cross-cutting cm-scale quartz veins

    The economic distribution and marketing of the lesser known fruit Dialium guineense Wild in Ghana has been studied using a structured questionnaire and the rapid appraisal system. The seasonality of the fruit (from January to May) makes it abundant in the peak season and rare or not all for the best part of the year. Some fruits also to waste in the peak season and rare or not all for the best part of the year. Some fruits also go to waste in the field owing to under exploitation. This thesis provides information on the resident fungi, mycological quality, sorption isotherm, and the effect of gamma irradiation and packaging on the physic-chemical properties of the fruit and the sensory evaluation of the pulp by a taste panel with the view to showing the economical and nutritional potential of the fruit. The resident fungi and mycological quality were assessed by the conventional decimal serial dilution technique and plating on three media (PDA, DG 18 and OGYE). Sorption isotherms at 29 {+-}1 degrees Celsius were determine under simulated Environmental Relative Humidity (20, 55, 65, 75, 85, 95%) provided by glycerol: water mixtures; physic-chemical properties were assessed by the method of the Association of Official Analytical Chemists. Descriptive and preference sensory evaluation were administered using prescribed international methods on a hedonic scale. The tamarind markets are in the southern sector of the country, namely Greater Accra, Eastern, Central, Ashanti and Volta Region. The local names of the fruit varied from one region to another.

    2014-01-01

    In this work a new carbonaceous material is presented with improved adsorption properties obtained by a heart treatment about 5 min from the shell tamarind. It was found that the samples obtained carbonaceous adsorbents are effective in removing Co 2+ (41 mg / g) ions in aqueous solutions. These samples were prepared from tamarind shell, urea, ammonium nitrate and water. The solution was subjected to a combustion process at different temperatures. Carbonaceous samples prepared in this manner were characterized by X-ray diffraction, infrared spectroscopy, scanning electron microscopy (Sem) and surface area measurements by Physisorption of N 2 . Changes in structure, morphology and texture were studied. The results show that this material is of great importance to the applications of adsorption of metal ions. The measurements of specific surface area (Bet) were 2.35 to 203.76 m 2 g -1 with pore diameters between 2.31 and 15.63 nm, indicating that the samples obtained are predominantly meso porous. The combustion process of the solution proved to be advantageous to improve the textural properties of the tamarind shell. The obtained carbonaceous material plays an important role in adsorption to remove cobalt in aqueous solutions. (Author)

    The elaboration of nanoparticles has become a field of great interest for many scientists. Nanoparticles possess different properties than those ones shown in bulk materials. Shape memory alloys have the exceptional ability to recuperate its original shape by simple heating after being 'plastically' deformed. When this process is originated, important changes in properties, as mechanical and electrical, are developed in bulk material. If there is possible to obtain nanoparticles with shape memory effects, these nanoparticles could be used in the elaboration of nanofluids with the ability to change their electrical and thermal conductivity with temperature changes, i.e., smart nanofluids. In this work, some recent results and discussion of TiNi nanoparticles obtained by ion beam milling directly from a TiNi wire with shape memory are presented. The nanoparticles obtained by this process are about 2 nm of diameter with a composition of Ti-41.0 at.% Ni. Synthesized nanoparticles elaborated by this method have an ordered structure

    2013-07-01

    Combustion of peanut and tamarind shells was studied in the conical fluidized-bed combustor using alumina sand as the bed material to prevent bed agglomeration. Morphological, thermogravimetric and kinetic characteristics were investigated to compare thermal and combustion reactivity between the biomass fuels. The thermogravimetric kinetics of the biomasses was fitted using the Coats-Redfern method. Experimental tests on the combustor were performed at 60 and 45 kg/h fuel feed rates, with excess air within 20-80%. Temperature and gas concentrations were measured along radial and axial directions in the reactor and at stack. The axial temperature and gas concentration profiles inside the combustor exhibited sensible effects of fuel properties and operating conditions on combustion and emission performance. High (≈ 99%) combustion efficiency and acceptable levels of CO, CxHy, and NO emissions are achievable when firing peanut shells at excess air of about 40%, whereas 60% is more preferable for burning tamarind shells.

    In this study, gelatin and carboxymethyl tamarind gum (CTG) were chemically cross-linked to control the delivery of aceclofenac from their interpenetrating network (IPNs). Infrared spectra, thermal and X-ray data supported that drug and polymer was compatible in the composite hydrogels. Irregularly shaped IPN microstructures were seen under field emission scanning electron microscope (FE-SEM). IPN system was capable of entrapping about 96% of the drug fed. CTG in IPN structures suppressed the drug release rate in HCl solution (pH 1.2); however extended the same in phosphate buffer solution (pH 6.8). The drug release was controlled by polymer chain relaxation/swelling and simple diffusion in vitro. The anti-inflammatory activity of drug-loaded biocomposites lasted over 7 h in albino rats, thus suggesting their potential as an anti-inflammatory therapeutics. - Highlights: • Novel gelatin-carboxymethyl tamarind gum biocomposites was synthesized. • FTIR, thermal and X-ray study ensured compatibility between drug and polymers. • FE-SEM image revealed irregular shape of the IPN microstructures. • In vivo anti-inflammatory pharmacodynamics in rat model was encouraging.

    A new composite cation exchanger, tamarind sulphonic acid (TSA) resin has been synthesized. The chemically modified TSA ion exchange resin has been used for the removal and preconcentration of Zn2+, Cd2+, Fe2+, Co2+ and Cu2+ ions in aqueous solution and effluent from the Laxmi steel plant in Jodhpur, India. This type of composite represents a new class of hybrid ion exchangers with good ion exchange capacity, stability, reproducibility and selectivity for toxic metal ions found in effluent from the steel industry. The characterization of the resin was carried out by determining the ion-exchange capacity, elemental analysis, pH titration, Fourier transform infrared spectra and thermal analysis. The distribution coefficients (K(d)) of toxic metal ions were determined in a reference aqueous solution and the steel plant effluent at different pH values; the absorbency of different metal ions on the TSA resin was studied for up to 10 cycles. The adsorption of different metal ions on TSA resin follows the order: Co2+ > Cu2+ > Zn2+ > Fe2+ > Cd2+. The ion exchange capacity of TSA resin is 2.87%.

    2014-11-01

    Full Text Available The aim of this study is to explore organizational policies and strategies regarding the institutional memory of Belgrade’s repertoire theaters. The concept of institutional (organizational memory has not been developed within the culture of memory theory. The role of theater in the culture of memory has been researched mostly through studies of its repertoire, corresponding to how theaters deal with issues of glory, guilt, or shame. This study explores how theaters rethink their own past and organizational culture, how they use their capacity for re-imagining themselves, for clarifying their role and function in different historical moments. The objective of this research is to identify the main institutional policies and types of strategies used for preserving institutional memory through key narratives of remembering, and key methods of inter-generational transfer. The sample comprises of four Belgrade-based public repertoire theaters: the Yugoslav Dramatic Theater (JDP, the Belgrade Dramatic Theater (BDP, Atelje 212, and Bitef Theater. Specific attention is given to the means of transmission, of individual (episodic memories into the collective consciousness, influencing organizational cultures and shaping a theater’s identity (semantic memory. Research has shown that there are important differences in active policies of preserving institutional memory among Belgrade’s theaters. Different organizational and programming strategies were implemented in order to safeguard institutional identity and memory, particularly in theaters with a permanent ensemble. The major difference is between theaters whose culture of memory might be called “non-existent” (Bitef, or “in storage” (BDP, and those succeeding in creating a functional memory (JDP, Atelje 212.

    Latina teen pregnancy rates continue to be a health disparity in the United States. This study evaluated a parenting intervention using interactive theater to facilitate Latino parent-adolescent communication about sexuality and pregnancy prevention. The intervention, conducted in Spanish and with teen actors, consisted of scenes involving the audience. Fifty-nine parents participated in this 3-month prospective study. Spanish measures of comfort with communication, general communication, and parent-child sexual communication were employed comparing paired t tests for each scale. Acceptability of the intervention was assessed and demonstrated. Eighty-six percent of parents used information from the performance to talk to their child. Improvements in general communication (p < .02), sexual communication (p < .001), and comfort (p < .001) occurred. Interactive theater is an innovative approach to facilitate Latino parent communication about sexuality and pregnancy prevention.

    To determine the safety of definitive in-theater facial fracture repair on American military personnel wounded during Operation Iraqi Freedom. A retrospective review of all patients with head and neck trauma treated at the 322nd Expeditionary Medical Group/Air Force Theater Hospital, Balad Air Base, Iraq, from May 7, 2005, through September 18, 2005, was performed. This study focused on the outcomes of wounded American military personnel whose facial fractures were definitively repaired in theater. The criteria used to determine candidacy for definitive in-theater facial fracture repair on American military personnel were (1) the fracture site was exposed through either a soft tissue wound or because of an adjacent surgical approach, (2) treatment would not delay evacuation from theater, and (3) treatment would allow the military member to remain in theater. From May 2005 to September 2005, 207 patients were taken to the operating room and required 388 procedures. A total of 175 patients (85%) were operated on for traumatic injuries, and 52 of these patients required open reduction and internal fixation (ORIF) of a facial fracture. Of the 52 patients who underwent an ORIF, 17 were American military personnel. Of the 17 American patients who were definitively treated for their facial fractures in theater, 16 were contacted and/or followed up on the global military medical database. None of these patients developed an Acinetobacter baumannii infection or had a complication caused by the definitive in-theater ORIF. The range of follow-up was 2 months to 11 months, with a mean of 8.3 months. Definitive repair of facial fractures with ORIF on American military personnel in theater is advised when the aforementioned criteria are observed. An otolaryngologist is a crucial member of the head and neck trauma team.

    Full Text Available In Japan, most of children haven't read the Fairy Tales or tales of old Japan because the high technology video games are more exciting than most of picture books. But they must be effective to bring up the children's cultivation of aesthetic sensitivity. And we have heard from teachers of elementary schools that most of themes of computer education in school are the operation of Painting Tool or Game Software. To improve these problems and to aid the courses of computer-based education in elementary school, we developed new educational support tool named Cyber Theater. Cyber Theater provides the capability of easy making the 3D-CG animation of children's story by using Script language named CTSL (Cyber Theater Scenario Language. We hope schoolteachers will be able to use Cyber Tales as teaching materials in elementary schools. We also hope that upper-aged students (including junior high school students are able to make their original CG-animation stories as the Creative Lesson.

    1994-01-01

    In the brief period between May 1978 and December 12, 1979, U.S. policy, and the policy of the NATO Alliance, toward theater nuclear forces (TNF) changed dramatically. The consequences of this change now dominate the political agenda in East-West (and West-West) relations. The ultimate outcome of the now renamed intermediate-range nuclear force (INF) debate will have far-reaching consequences for the future of the Atlantic Alliance. How did this issue emerge? Why did the US change its policy? How did it work with its Alliance to change NATO policy? These questions, among others, are now figuring in the debate. The answers to these questions are discussed in detail

    1994-01-01

    Soviet theater nuclear forces were a major pillar of Soviet superpower strength, rising sharply under Krushchev in the latter 1950s to their zenith under Brezhnev twenty years later. Most recently they have begun their decline under Gorbachev, and while not yet facing extinction, may be headed for a much reduced role under the new thinking in the USSR. This paper deals with the Soviet TNF in six periods of their life: The Post-war Stalin Period (1945-1953), the Post-Stalin Period (1953-1955), The Transition Period (1955-1959), The Period of Nuclear Revolution (1960-1964), The Period of Modern TNF Planning (1965-1980), and The Period of Non-nuclear Planning (1980-1987)

    A prototype web enabled distributed instrumentation system is being proposed in the Department of Electronics Science, Gauhati University, Assam, India. The distributed instrumentation system contains sensors, legacy hardware, TCP/IP protocol converter, TCP/IP network Ethernet, Database Server, Web/Application Server and Client PCs. As part of the proposed work, Tiny Internet Interface (TINI, TBM390: Dallas Semiconductor) has been deployed as TCP/IP stack, and java programming language as software tools. A feature supported by Java, that is particularly relevant to the distributed system is its applet. An applet is a java class that can be downloaded from the web server and can be run in a context application such as web browser or an applet viewer. TINI has been installed as TCP/IP stack, as it is the best suited embedded system with java programming language and it has been uniquely designed for communicating over One Wire Devices (OWD) over network. Here we will discuss the hardware and software aspects of TINI with OWD for the present system. (author)

    The interplay of architecture and acoustics is remarkable in ancient Greek and Roman theaters. Frequently they are nowadays lively performance spaces and the knowledge of the sound field inside them is still an issue of relevant importance. Even if the transition from Greek to Roman theaters can be described with a great architectural detail, a comprehensive and objective approach to the two types of spaces from the acoustical point of view is available at present only as a computer model study [P. Chourmouziadou and J. Kang, "Acoustic evolution of ancient Greek and Roman theaters," Appl. Acoust. 69, re (2007)]. This work addresses the same topic from the experimental point of view, and its aim is to provide a basis to the acoustical evolution from Greek to Roman theater design. First, by means of in situ and scale model measurements, the most important features of the sound field in ancient theaters are clarified and discussed. Then it has been possible to match quantitatively the role of some remarkable architectural design variables with acoustics, and it is seen how this criterion can be used effectively to define different groups of ancient theaters. Finally some more specific wave phenomena are addressed and discussed.

    Active neutrino masses are extremely smaller than those of other quarks and leptons, and there are large flavor mixings in the lepton sector, contrary to the quark sector. They are great mysteries in the standard model, but also excellent hints of new physics beyond the standard model. Thus, questions 'What is an origin of tiny neutrino mass?' and 'What is an origin of large lepton flavor mixings?' are very important. In this paper, we overview various attempts to solve these big questions. (author)

    In this work a new carbonaceous material is presented with improved adsorption properties obtained by a heart treatment about 5 min from the shell tamarind. It was found that the samples obtained carbonaceous adsorbents are effective in removing Co{sup 2+} (41 mg / g) ions in aqueous solutions. These samples were prepared from tamarind shell, urea, ammonium nitrate and water. The solution was subjected to a combustion process at different temperatures. Carbonaceous samples prepared in this manner were characterized by X-ray diffraction, infrared spectroscopy, scanning electron microscopy (Sem) and surface area measurements by Physisorption of N{sub 2}. Changes in structure, morphology and texture were studied. The results show that this material is of great importance to the applications of adsorption of metal ions. The measurements of specific surface area (Bet) were 2.35 to 203.76 m{sup 2} g{sup -1} with pore diameters between 2.31 and 15.63 nm, indicating that the samples obtained are predominantly meso porous. The combustion process of the solution proved to be advantageous to improve the textural properties of the tamarind shell. The obtained carbonaceous material plays an important role in adsorption to remove cobalt in aqueous solutions. (Author)

    Peroxidase activities from four different varieties of plant roots were investigated through the use of UV-Vis spectrophotometer. Hydrogen peroxide was used as the substrate and phosphate buffer at a pH that have been determined to be the optimal pH for peroxidase activity for the specific sample type. The four plant root extracts showed an assay pH optimum of 7.5 for the Tamarindus indica (tamarind) and Eichhornia crassipes (water hyacinth), pH 5.5 for Dracaena surculosa (spotted dracaena) and pH 7.0 for Caulerpa lentillifera (grapes seaweeds) using Maehly and Chance method. Determination of peroxidase at 510 nm of the four extracts indicated that, spotted dracaena gave the highest peroxidase activity with 361.07 U ml -1 , followed by tamarind with 57.11 U ml -1 , then water hyacinth with 29.39 U m -1 and lastly, grapes seaweeds with 7.55 U ml -1 . The specific peroxidase activities of the spotted dracaena, water hyacinth, tamarind and grapes seaweeds are 0.3224, 0.2048, 0.0721 and 0.0341 U mg -1 respectively. The peroxidase of the four plant tissues that were kept at ultra low personal freezer for almost a week was degraded. (Authors)

    1988-01-01

    Mali's branch of the International Planned Parenthood Federation has found a vehicle that effectively conveys the idea of family planning through the use of contraception, a method that blends the country's cultural heritage and modern technology. Despite becoming the first sub-Saharan francophone country to promote family planning, Mali only counted 1% of its population using a modern method of contraception. So with the aid of The Johns Hopkins University/Population COmmunication Services (JHU/PCS), the Association Malienne pour la Protection et la Promotion de la Famille (AMPPF) developed several programs to promote contraception, but none were more successful than the Koteba Project, which used Mali's traditional theater form to communicate the message. While comical, the Koteba generally deals with social issues -- it informs and entertains. This particular Koteba told the story of two government employees, one with two wives and many children, the other with one wife and few children. The first one sees nothing but family problems: fighting wives and delinquent children. The second one, who had used family planning, enjoys a peaceful home. Upon hearing of his friend's successes with family planning, the tormented government employee becomes convinced of its needs, and persuades his wives to accompany him to a family planning clinic. Developed at a cost of approximately US $3000 and televised nationwide, the Koteba proved effective. A survey of 500 people attending an AMPPF clinic revealed that 1/4 of them remembered the program. With the success of the Koteba, JHU/PCS and AMPPF are now exploring other traditional channels of communication.

    2012-11-01

    Full Text Available Jan Fabre is one of the most controversial European scene figures. His interests range from visual arts to theater and dance. His works, disturbing and provocative, are very contemporary in style and language, while referring to the tradition of Flemish painting. With his performances Fabre demolishes traditional theatre conventions. Theatrical device questioning leads him to disorganize dynamics of representation and to elaborate the concept of crisis until death and apocalypse boundaries. In representing death, Fabre revives theater, according to the principle of metamorphosis. His entire choreography can be defined by balance seeking between opposite poles, good and evil, stasis and movement, beauty and chaos, life and death.

    The present study was undertaken to apply the laser welding to the joining of a shape memory alloy. Butt welding of a Ti-Ni type shape memory alloy was performed using 10 kW CO 2 laser. The laser welded specimens showed successfully the shape memory effect and super elasticity. These properties were approximately identical with those of the base metal. The change in super elasticity of the welded specimen during tension cycling was investigated. Significant changes in stress-strain curves and residual strain were not observed in the laser welded specimen after the 50-time cyclic test. The weld metal exhibited the celler dendrite. It was revealed by electron diffraction analysis that the phase of the weld metal was the TiNi phase of B2 structure which is the same as the parent phase of base metal and oxide inclusions crystallized at the dendrite boundary. However, oxygen contamination in the weld metal by laser welding did not occur because there was almost no difference in oxygen content between the base metal and the weld metal. The transformation temperatures of the weld metal were almost the same as those of the base metal. From these results, laser welding is applicable to the joining of the Ti-Ni type shape memory alloy. As the application of laser welding to new shape memory devices, the multiplex shape memory device of welded Ti-50.5 at % Ni and Ti-51.0 at % Ni was produced. The device showed two-stage shape memory effects due to the difference in transformation temperature between the two shape memory alloys. (author)

    Pirate copies of feature films are proliferating on the Internet. DVD rip or screener recording methods involve the duplication of officially distributed media whereas 'cam' versions are illicitly captured with handheld camcorders in movie theaters. Several, complementary, multimedia forensic techniques such as copy identification, forensic tracking marks or sensor forensics can deter those clandestine recordings. In the case of camcorder capture in a theater, the image is often geometrically distorted, the main artifact being the trapezoidal effect, also known as 'keystoning', due to a capture viewing axis not being perpendicular to the screen. In this paper we propose to analyze the geometric distortions in a pirate copy to determine the camcorder viewing angle to the screen perpendicular and derive the approximate position of the pirate in the theater. The problem is first of all geometrically defined, by describing the general projection and capture setup, and by identifying unknown parameters and estimates. The estimation approach based on the identification of an eight-parameter homographic model of the 'keystoning' effect is then presented. A validation experiment based on ground truth collected in a real movie theater is reported, and the accuracy of the proposed method is assessed.

    High sensitivity pressure sensors are crucial for the ultra-sensitive touch technology and E-skin, especially at the tiny pressure range below 100 Pa. However, it is highly challenging to substantially promote sensitivity beyond the current level at several to two hundred kPa -1 , and to improve the detection limit lower than 0.1 Pa, which is significant for the development of pressure sensors toward ultrasensitive and highly precise detection. Here, we develop an efficient strategy to greatly improve the sensitivity near to 2000 kPa -1 by using short channel coplanar device structure and sharp microstructure, which is systematically proposed for the first time and rationalized by the mathematic calculation and analysis. Significantly, benefiting from the ultrahigh sensitivity, the detection limit is improved to be as small as 0.075 Pa. The sensitivity and detection limit are both superior to the current levels, and far surpass the function of human skin. Furthermore, the sensor shows fast response time (50 μs), excellent reproducibility and stability, and low power consumption. Remarkably, the sensor shows excellent detection capacity in the tiny pressure range including LED switching with a pressure of 7 Pa, ringtone (2-20 Pa) recognition, and ultrasensitive (0.1 Pa) electronic glove. This work represents a performance and strategic progress in the field of pressure sensing.

    Sea butterflies, also known as pteropods, include a variety of small, zooplanktonic marine snails. Thecosomatous pteropods possess a shell and swim at low Reynolds numbers by beating their wing-like parapodia in a manner reminiscent of insect flight. In fact, previous studies of the pteropod Limacina helicina have shown that pteropod swimming hydrodynamics and tiny insect flight aerodynamics are dynamically similar. Studies of L. helicina swimming have been performed in polar (0 degrees C) and temperate conditions (12 degrees C). Here we present measurements of the swimming of Heliconoides inflatus, a smaller yet morphologically similar pteropod that lives in warm Bermuda seawater (21 degrees C) with a viscosity almost half that of the polar seawater. The collected H. inflatus have shell sizes less than 1.5 mm in diameter, beat their wings at frequencies up to 11 Hz, and swim upwards in sawtooth trajectories at speeds up to approximately 25 mm/s. Using three-dimensional wing and body kinematics collected with two orthogonal high speed cameras and time-resolved, 2D flow measurements collected with a micro-PIV system, we compare the effects of smaller body size and lower water viscosity on the flow physics underlying flapping-based swimming by pteropods and flight by tiny insects.

    Full Text Available A new pH-sensing film was developed by using tamarind seed polysaccharide (TSP and natural dye extracted from litmus lichen (LLE. The addition of LLE from 0 to 2.5% decreased the tensile strength and elongation at break from 30.20 to 29.97 MPa and 69.73% to 60.13%, respectively, but increased the water vapor permeability from 0.399 × 10−9 to 0.434 × 10−9 g·s−1·m−1·Pa−1. The UV–Vis spectra of the litmus lichen extract (LLE in the pH range of 4–10 showed that the color clearly changed from orange to blue. The characterization results showed that TSP interacted with LLE through hydrogen bonds. The color of the film varied from orange (pH 4.0 to blue-violet (pH 10.0. The full cream milk spoilage test indicated that the film is suitable for application in full cream milk spoilage detection. The developed pH-sensing film could be used as a promising diagnostic tool for the detection of food spoilage.

    In the present study, Lansoprazole pellets were prepared employing a novel excipient Carboxymethyl tamarind kernel powder (CMTKP) using extrusion-spheronization technique. Various research studies including patents have been carried out on this polymer. Pellet formulation was optimized for formulation parameters (concentration of microcrystalline cellulose, CMTKP, croscarmellose sodium and isopropyl alcohol). Process parameters (speed and duration of spheronization) were optimized using factorial design. The pellets were evaluated for yield, bulk and tapped density, particle size, hardness, drug content, disintegration time and drug release. The optimized batch showed 93.53% yield, 0.307 kg/cm2 hardness, 2.15 mm average particle size, 292 sec disintegration time and 90.46% drug content. Drug release of the optimized batch (2F7) and marketed formulation (LANZOL cap) was found to be 82.33% and 80.07%, respectively. An accelerated study indicated that optimized formulation was stable.

    New thermo associating polymers were designed and synthesized by grafting amino terminated poly(ethylene oxide-co-propylene oxide) (PEPO) onto carboxymethyl guar (CMG) and carboxymethyl tamarind (CMT). The grafting was performed by coupling reaction between NH2 groups of PEPO and COOH groups of CMG and CMT using water-soluble EDC/NHS as coupling agents. The grafting efficiency and the temperature of thermo-association, T(assoc) in the copolymer were studied by NMR spectroscopy. The graft copolymers, CMG-g-PEPO and CMT-g-PEPO exhibited interesting thermo-associating behavior which was evidenced by the detailed rheological and fluorescence measurements. The visco-elastic properties (storage modulus, G'; loss modulus, G") of the copolymer solutions were investigated using oscillatory shear experiments. The influence of salt and surfactant on the T(assoc) was also studied by rheology, where the phenomenon of "Salting out" and "Salting in" was observed for salt and surfactant, respectively, which can give an easy access to tunable properties of these copolymers. These thermo-associating polymers with biodegradable nature of CMG and CMT can have potential applications as smart injectables in controlled release technology and as thickeners in cosmetics and pharmaceutical formulations.

    To gather qualitative descriptions of music theater vocal qualities including belt, legit, and mix from expert pedagogues to better define this voice type. This is a prospective, semistructured interview. Twelve expert teachers from United States, United Kingdom, Asia, and Australia were interviewed by Skype and asked to identify characteristics of music theater vocal qualities including vocal production, physiology, esthetics, pitch range, and pedagogical techniques. Responses were compared with published studies on music theater voice. Belt and legit were generally described as distinct sounds with differing physiological and technical requirements. Teachers were concerned that belt should be taught "safely" to minimize vocal health risks. There was consensus between teachers and published research on the physiology of the glottis and vocal tract; however, teachers were not in agreement about breathing techniques. Neither were teachers in agreement about the meaning of "mix." Most participants described belt as heavily weighted, thick folds, thyroarytenoid-dominant, or chest register; however, there was no consensus on an appropriate term. Belt substyles were named and generally categorized by weightedness or tone color. Descriptions of male belt were less clear than for female belt. This survey provides an overview of expert pedagogical perspectives on the characteristics of belt, legit, and mix qualities in the music theater voice. Although teacher responses are generally in agreement with published research, there are still many controversial issues and gaps in knowledge and understanding of this vocal technique. Breathing techniques, vocal range, mix, male belt, and vocal registers require continuing investigation so that we can learn more about efficient and healthy vocal function in music theater singing.

    Impact stress transmission of Ti-Ni alloy was evaluated for biomedical stress shielding. Transformation temperatures of the alloy were investigated by means of DSC. An impact compression test was carried out with use of split-Hopkinson pressure-bar technique with cylindrical specimens of Ti-Ni alloy, titanium and stainless steel. As a result, the transmitted pulse through Ti-Ni alloy was considerably depressed as compared with those through titanium and stainless steel. The initial stress reduction was large through Ti-Ni alloy and titanium, but the stress reduction through Ti-Ni alloy was more continuous than titanium. The maximum value in the stress difference between incident and transmitted pulses through Ti-Ni alloy or titanium was higher than that through stainless steel, while the stress reduction in the maximum stress through Ti-Ni alloy was statistically larger than that through titanium or stainless steel. Ti-Ni alloy transmitted less impact stress than titanium or stainless steel, which suggested that the loading stress to adjacent tissues could be decreased with use of Ti-Ni alloy as a component material in an implant system.

    Highlights: ► The carbonization of Tamarind fruit shell improved its defluoridation efficiency. ► Calcium carbonate particles were involved in the defluoridation process. ► Adsorbent dose, pH, and fluoride concentration showed significant effects. ► Maximum adsorption of fluoride was achieved at pH 7–8. ► Prepared carbons were efficient in treating three natural waters. - Abstract: Tamarindus indica fruit shells (TIFSs) are naturally calcium rich compounds. They were impregnated with ammonium carbonate and then carbonized, leading to ammonium carbonate activated ACA-TIFS carbon. The resulting materials and carbon arising from virgin fruit shells V-TIFS were characterized and assayed as adsorbent for the removal of fluoride anions from groundwater. The fluoride scavenging ability of TIFS carbons was due to naturally dispersed calcium compounds. X-ray diffraction (XRD) showed that TIFS carbon contained a mixture of calcium oxalate and calcium carbonate. Batch studies on the fluoride removal efficiency of TIFS carbons with respect to contact time, pH, initial fluoride concentration, and co-ion interference were conducted. Applicability of various kinetic models (viz., pseudo-first-order, pseudo-second-order, intra-particle diffusion and Elovich) and sorption isotherms were tested for batch techniques. The fluoride removal capacity of TIFS carbons was found to be 91% and 83% at a pH of 7.05 for V-TIFS and ACA-TIFS carbons, respectively. The practical applicability of TIFS carbons using groundwater samples was approved. The fluoride removal was greater in groundwater without hydrogen carbonate ions than those containing these ions. The characterizations of fluoride unloaded and loaded TIFS carbons were done by SEM and XRD studies.

    Palm kernel cake (PKC), the residue obtained after extraction of palm oil from oil palm seeds and tamarind seed powder (TSP) obtained after removing the fruit pulp from tamarind fruit pod were tested for the production of tannase under solid-state fermentation (SSF) using Aspergillus niger ATCC 16620. The fungal strain was grown on the substrates without any pretreatment. In PKC medium, a maximum enzyme yield of 13.03 IU/g dry substrate (gds) was obtained when SSF was carried out at 30 degrees C, 53.5% initial substrate moisture, 33 x 10(9) spores/5 g substrate inoculum size and 5% tannic acid as additional carbon source after 96 h of fermentation. In TSP medium, maximum tannase yield of 6.44 IU/gds was obtained at 30 degrees C, 65.75% initial substrate moisture, 11 x 10(9) spores/5 g substrate inoculum, 1% glycerol as additional carbon source and 1% potassium nitrate as additional nitrogen source after 120 h of fermentation. Results from the study are promising for the economic utilization and value addition of these important agro residues, which are abundantly available in many tropical and subtropical countries.

The question of what preceded and caused the holding of the first performance in the Ukrainian language by the Ukrainian Professional Drama Theatre in January 1882 in Kyiv was investigated. The importance of this event for the Ukrainian society and the development of the Ukrainian Professional Drama Theatre as a whole was revealed. It is noted that in her memories L.M. Staryts’ka-Cherniakhivs’ka emphasized the value of the performance of Ukrainian Professional Drama Theater in Kyiv for the Ukrainian community. She wrote that the spectators filled the lobby and corridors, faces of all present viewers were burning from ardor and enthusiasm, their eyes were shining, there was a lively noise, the native Ukrainian language rang everywhere in the theater.  She noted that the spectators were dressed in Ukrainian national clothes, there were visible bright suits of Ukrainian women in the theater lodges, many children and parents were dressed in Ukrainian costumes in the theater lodges, there could be heard everywhere the native Ukrainian language in the theater. There was the abundance of the heart everywhere. It is found that the partial lifting of restrictions on the Ukrainian staging plays in 1881, made possible for Kyiviets to see the first performance of the Ukrainian Professional Drama Theatre in the Ukrainian language in 1882.

    One of the reasons for climate change (i.e., stratospheric ozone concentrations) is connected with the variations in optical thickness of aerosols in the upper sphere of the atmosphere (at altitudes over 30 km). Therefore, aerosol and gas components of the atmosphere are crucial in the study of the ultraviolet (UV) radiation passing upon the Earth. Moreover, a scrupulous study of aerosol components of the Earth atmosphere at an altitude of 30 km (i.e., stratospheric aerosol), such as the size of particles, the real part of refractive index, optical thickness and its horizontal structure, concentration of ozone or the upper border of the stratospheric ozone layer is an important task in the research of the Earth climate change. At present, the Main Astronomical Observatory of the National Academy of Sciences (NAS) of Ukraine, the National Technical University of Ukraine "KPI"and the Lviv Polytechnic National University are engaged in the development of methodologies for the study of stratospheric aerosol by means of ultraviolet polarimeter using a microsatellite. So fare, there has been created a sample of a tiny ultraviolet polarimeter (UVP) which is considered to be a basic model for carrying out space experiments regarding the impact of the changes in stratospheric aerosols on both global and local climate.

    Full Text Available Ticks are tiny crawling bugs in the spider family that feed by sucking blood from animals. They are second only to mosquitoes as vectors of human disease, both infectious and toxic. Infected ticks spread over a hundred diseases, some of which are fatal if undetected. They spread the spirochete (which multiplies in the insect's gut with a subsequent bite to the next host. We describe the only reported cases of peri ocular tick bite from India that presented to us within a span of 3 days and its management. Due suspicion and magnification of the lesions revealed the ticks which otherwise masqueraded as small skin tags/moles on gross examination. The ticks were firmly latched on to the skin and careful removal prevented incarceration of the mouth parts. Rickettsial diseases that were believed to have disappeared from India are reemerging and their presence has recently been documented in at least 11 states in the country. Among vector borne diseases, the most common, Lyme disease, also known as the great mimicker, can present with rheumatoid arthritis, fibromyalgia, depression, attention deficit hyperactivity disorder, multiple sclerosis, chronic fatigue syndrome, cardiac manifestations, encephalitis, and mental illness, to name some of the many associations. Common ocular symptoms and signs include conjunctivitis, keratitis, uveitis, and retinitis. Early detection and treatment of tick borne diseases is important to prevent multi system complications that can develop later in life.

    Tectonic forces and surface erosion lead to the exhumation of rocks from the Earth's interior. Those rocks can be characterized by many variables including peak pressure and temperature, composition and exhumation duration. Among them, the duration of exhumation in different geological settings can vary by more than ten orders of magnitude (from hours to billion years). Constraining the duration is critical and often challenging in geological studies particularly for rapid magma ascent. Here, we show that the time information can be reconstructed using a simple combination of laser Raman spectroscopic data from mineral inclusions with mechanical solutions for viscous relaxation of the host. The application of our model to several representative geological settings yields best results for short events such as kimberlite magma ascent (less than ~4,500 hours) and a decompression lasting up to ~17 million years for high-pressure metamorphic rocks. This is the first precise time information obtained from direct microstructural observations applying a purely mechanical perspective. We show an unprecedented geological value of tiny mineral inclusions as timekeepers that contributes to a better understanding on the large-scale tectonic history and thus has significant implications for a new generation of geodynamic models.

  2. Purple Salt and Tiny Drops of Water in Meteorites

    Taylor, G. J.

    1999-12-01

    Some meteorites, especially those called carbonaceous chondrites, have been greatly affected by reaction with water on the asteroids in which they formed. These reactions, which took place during the first 10 million years of the Solar System's history, formed assorted water-bearing minerals, but nobody has found any of the water that caused the alteration. Nobody, that is, until now. Michael Zolensky and team of scientists from the Johnson Space Center in Houston and Virginia Tech (Blacksburg, Virginia) discovered strikingly purple sodium chloride (table salt) crystals in two meteorites. The salt contains tiny droplets of salt water (with some other elements dissolved in it). The salt is as old as the Solar System, so the water trapped inside the salt is also ancient. It might give us clues to the nature of the water that so pervasively altered carbonaceous chondrites and formed oceans on Europa and perhaps other icy satellites. However, how the salt got into the two meteorites and how it trapped the water remains a mystery - at least for now.

  3. Establishing the tolerability and performance of tamarind seed polysaccharide (TSP in treating dry eye syndrome: results of a clinical study

    Directory of Open Access Journals (Sweden)

    Valente Cristiana

    2007-03-01

    Full Text Available Abstract Background One of the problems arising from available preparations for dry eye syndrome is the limited residence time of products on the ocular surface. In this paper, we look at an innovative new treatment for dry eye, tamarind seed polysaccharide (TSP. TSP possesses mucomimetic, mucoadhesive and pseudoplastic properties. The 'mucin-like' molecular structure of TSP is similar to corneal and conjunctival mucin 1 (MUC1, a transmembrane glycoprotein thought to play an essential role in protecting and wetting the corneal surface and may explain its increased retention on the eye surface. Methods The activity of TSP and hyaluronic acid (HA in the treatment of dry eye syndrome was compared in an open-label, randomised, single-centre clinical study. Thirty patients were randomised to receive three or more applications per day of either TSP 0.5%, TSP 1% or HA 0.2% (Hyalistil™ over a period of 90 days. The primary objective of tolerability was assessed by visual analogue scale (VAS, scoring of specific symptoms and the incidence of adverse events. Secondary objectives included improvement in stability of the precorneal tear film, subjective symptoms and corneal and conjunctival staining. Results TSP 0.5% and 1% were comparable to HA 0.2% with regard to both primary and secondary objective parameters. TSP 1% showed benefits over HA 0.2% for the subjective symptoms; trouble blinking, ocular burning and foreign body sensation. Conclusion This study suggests that TSP 0.5% and 1% offer at least equivalent relief to HA 0.2% for dry eye syndrome. All treatments demonstrated optimal tolerability and are suitable for frequent use in the therapy of dry eye. TSP 1% produced promising results in terms of improvements in certain patient symptoms and suggests benefits of the TSP formulation. This study paves the way for a larger study to further establish the performance and safety of TSP compared with HA and highlights the need to expand this therapeutic

    Influenza is an acute respiratory infectious disease with a high incidence rate in the Chinese army, which directly disturbs military training and affects soldiers' health. Influenza surveillance systems are widely used around the world and play an important role in influenza epidemic prevention and control. As a theater centers for disease prevention and control, we established an influenza monitoring platform (IMP) in 2014 to strengthen the monitoring of influenza-like illness and influenza virus infection. In this study, we introduced the constitution, influenza virus detection, and quality control for an IMP. The monitoring effect was also evaluated by comparing the monitoring data with data from national influenza surveillance systems. The experiences and problems associated with the platform also were summarized. A theater IMP was established based on 3 levels of medical units, including monitoring sites, testing laboratories and a checking laboratory. A series of measures were taken to guarantee the quality of monitoring, such as technical training, a unified process, sufficient supervision and timely communication. The platform has run smoothly for 3 monitoring years to date. In the 2014-2015 and 2016-2017 monitoring years, sample amount coincided with that obtained from the National Influenza Surveillance program. In the 2015-2016 monitoring year, due to the strict prevention and control measures, an influenza epidemic peak was avoided in monitoring units, and the monitoring data did not coincide with that of the National Influenza Surveillance program. Several problems, including insufficient attention, unreasonable administrative intervention or subordination relationships, and the necessity of detection in monitoring sites were still observed. A theater IMP was established rationally and played a deserved role in the prevention and control of influenza. However, several problems remain to be solved.

    Full Text Available The anthropology of performance, as understood by Victor Turner, provides interesting perspectives for the analysis of what may be referred to as the "theater of bóias-frias". Conversely, this theater may be of special interest for purposes of rethinking some of the main propositions which have arisen on the borders between anthropology and performance. Considering the specificity of "the practice which calculates the place from which one views things" of this theater, several topics present themselves as guidelines for the text which follows: 1 social dramas, 2 relations between social and aesthetic dramas, 3 symbols and montage, and 4 theater paradigms in anthropology. In this exercise to rethink some of the "classic" contributions of Victor Turner, Erving Goffman, and Richard Schechner, "elective affinities" have been found between, on the one hand, the writings of Walter Benjamin and Brechtian theater, and, on the other, the dramaturgical principles of the bóias-frias.

    TiNi films were prepared by co-sputtering TiNi and Ti targets. X-ray photoelectron spectroscopy (XPS) was employed to study surface chemistry of the films and interfacial structure of Si/TiNi system. Exposure of the TiNi film to the ambient atmosphere (23 deg. C and 80% relatively humidity) facilitated quick adsorption of oxygen and carbon on the surface. With time, carbon and oxygen content increased drastically at the surface, while oxygen diffused further into the layer. After a year, carbon content at the surface became as high as 65.57% and Ni dropped below the detection limit of XPS. Depth profiling revealed that significant inter-diffusion occurred between TiNi film and Si substrate with a layer of 90-100 nm. The detailed bond changes of different elements with depth were obtained using XPS and the formation of titanium silicides at the interface were identified

    Nanoparticles are a state of matter that have properties different from either molecules or bulk solids, turning them into a very interesting class of materials to study. In the present work, the crystal structure of TiNi nanoparticles obtained by ion beam deposition is characterized. TiNi nanoparticles were obtained from TiNi wire samples by sputtering with Ar ions using a Gatan precision ion polishing system. The TiNi nanoparticles were deposited on a Lacey carbon film that was used for characterization by transmission electron microscopy. The nanoparticles were characterized by high-resolution transmission electron microscopy, high-angle annular dark-field imaging, electron diffraction, scanning transmission electron microscopy and energy-dispersive X-ray spectroscopy. Results of nanodiffraction seem to indicate that the nanoparticles keep the same B2 crystal structure as the bulk material but with a decreased lattice parameter

    Previously the cost and extremely limited capabilities of sensors prohibited Quality of Service (QoS) implementations in wireless sensor networks. With advances in technology, sensors are becoming significantly less expensive and the increases in computational and storage capabilities are opening the door for new, sophisticated algorithms to be implemented. Newer sensor network applications require higher data rates with more stringent priority requirements. We introduce a dynamic scheduling algorithm to improve bandwidth for high priority data in sensor networks, called Tiny-DWFQ. Our Tiny-Dynamic Weighted Fair Queuing scheduling algorithm allows for dynamic QoS for prioritized communications by continually adjusting the treatment of communication packages according to their priorities and the current level of network congestion. For performance evaluation, we tested Tiny-DWFQ, Tiny-WFQ (traditional WFQ algorithm implemented in TinyOS), and FIFO queues on an Imote2-based wireless sensor network and report their throughput and packet loss. Our results show that Tiny-DWFQ performs better in all test cases. ?? 2009 IEEE.

  16. The martensitic transformation in Ti-rich TiNi shape memory alloys

    The martensitic (Ms) transformation temperatures and their ΔH values of Ti 51 Ni 49 and Ti 50.5 Ni 49.5 alloys are higher than those of equiatomic or Ni-rich TiNi alloys. The Ti-rich TiNi alloys exhibit good shape recovery in spite of a great deal of second phase Ti 2 Ni or Ti 4 Ni 2 O existing around B2 grain boundaries. The nearly identical transformation temperatures indicate that the absorbed oxygen in Ti-rich TiNi alloys may react with Ti 2 Ni particles, instead of the TiNi matrix, to form Ti 4 Ni 2 O. Martensite stabilization can be induced by cold rolling at room temperature. Thermal cycling can depress the transformation temperatures significantly, especially in the initial 20 cycles. The R-phase transformation can be promoted by both cold rolling and thermal cycling in Ti-rich TiNi alloys due to introduced dislocations depressing the Ms temperature. The strengthening effects of cold rolling and thermal cycling on the Ms temperature of Ti-rich TiNi alloys are found to follow the expression Ms = To - KΔσ y . The K values are affected by different strengthening processes and related to the as-annealed transformation temperatures. The higher the as-annealed Ms (or As), the larger the K value. (orig.)

  18. Enhancing Teaching, Adaptability and Presentation Skills through Improvisational Theater

    2014-10-01

    Full Text Available Improvisational theater, creative role-playing and open-ended scenarios are increasingly being used as ways to emphasize the importance of combining planning with flexibility and evolution to respond to changes in context. These skills and capabilities are extremely valuable in teaching, especially for strengthening communication and interpersonal skills, as well as the capacity for critical thinking and problem solving. Further, this combination of planning with flexibility is also a major theme of agile software development and a number of other problem-solving domains, and in the collaborative development of intellectual property in technical areas. With improvisation, the plan becomes less of a fixed framework, and more of a guideline. In software engineering, it becomes a mutable structure on which to hang goals and objectives, progress, processes, artifacts, and properties. In this submission, we explore the ramifications of this approach.

    Combat injuries are more often associated with blast, penetrating, and high-energy mechanisms than civilian trauma, generating controversy about the management of combat colonic injury. Despite implementation of mandatory colostomy in World War II, recent civilian data suggest that primary repair without diversion is safe and feasible. This study describes the modern management of battle-related colonic injuries and seeks to determine whether management strategy affects early complications. Records from the combat theater (downrange) and tertiary referral center in Germany were retrospectively reviewed from 2005 to 2006. Patient characteristics, management strategy, treatment course, and early complications were recorded. Comparison groups by management strategy were as follows: primary repair, diversion, and damage control. A total of 133 (97% male) patients sustained colonic injuries from penetrating (71%), blunt (5%), and blast (23%) mechanisms. Average injury severity score was 21 and length of stay in the referral center was 7.1 days. Injury distribution was 21% ascending, 21% descending, 15% transverse, 27% sigmoid, and 25% rectum. Downrange complications for primary repair, initial ostomy, and damage control groups were 14%, 15%, and 30%, respectively. On discharge from the center, 62% of patients had undergone a diversion. The complication rate was 18% overall and was unrelated to management strategy (P = .16). Multivariate analysis did not identify independent predictors of complications. Early complications were similar by mechanism, anatomic location, severity of injury, and management strategy. More diversions were performed for rectosigmoid injury. Good surgical judgment allows for low morbidity and supports primary repair in selected cases. Damage control surgery is effective in a multinational theater of operations.

  1. Moving social work norms via theater for senior farmers.

    Senior farmers have a 2.6-fold risk of fatal injury compared to their younger counterparts. Usual educational interventions have resulted in limited success in reducing injury. An innovative strategy, didactic readers theater, was piloted. Farmers' stories provided the foundation for the scripts. The approach incorporated adult learning strategies based on Ajzen's Theory of Planned Behavior. The intervention was marketed as a "dinner theater" to farm couples. Three short socio-novels (plays) were presented by local farmers who served as actors. Following each play participants completed a reaction form and participated in a short discussion about the play's content. One week later a phone survey was completed that tapped further reaction to the content and behavior changes. Thirty-three farm household individuals (including 16 couples) participated. Participants expressed favorable reaction to the intervention. Within one week post intervention, 42% had made safety changes and 67% were "thinking about/intending" to make changes. The use of real stories contributed to the success of this intervention. Farmers identified with the stories and began to think and talk about the impact that aging exerts on their health and safety. Interaction among the group identified work modifications which empowered the farmers to make positive changes in their own work behavior. Educational interventions with farmers have met with limited success in reducing farm-related injuries. Moreover, few interventions have utilized the family unit. This novel program, incorporating local organizations and using limited financial resources, resulted in swift behavior changes. Total Worker Health includes not only the worker, but also the family. Interventions that include family units should be considered when possible. This format is effective, easily adapted to local issues, can be delivered using existing infrastructure, and is acceptable to the farm community. It is currently being tested

    Full Text Available Theatrical art had a significant influence on the formation of social and cultural space of the city at all times. Currently Khabarovsk is one of the theatrical art centres in the Russian Far East. In this regional center theaters of different genres and periods exist. To study the Khabarovsk puppet theater is relevant because of growing interest of viewers of different ages to its activity, as well as the increasing role of the theater in the cultural and social development of the Far Eastern region. The puppet theater was created and later revived in the period of social modernization of the 1920s and 1990s. The paper attempts to identify the causes of the popularization of puppet theaters in certain historical periods. The peculiarities of a puppet genre can be explained by the Russian Far East situation at that time that created the appearance of the city puppeteers in the theatrical space whose work accumulated all the best traditions of Russian and the world puppet genre. Archive documentation analysis allowed creating a holistic view of the puppet theater major directions in the period of radical transformation of the 1990s.

    Creative arts have been increasingly implemented in medical education. This study investigated the use of interactive theater and role play with professional actors in teaching breaking bad news to medical students. The objectives were to explore the contexts, approaches, experiences, and reactions in giving and receiving bad news. Second-year medical students participated in a required educational session that utilized interactive theater which helps students learn about the issues of breaking bad news to a patient with cancer. Following the interactive theater piece, professional actors provided students role play experiences in small groups with breaking bad news. Anonymous evaluation surveys were given out to all second-year medical students at the conclusion of the breaking bad news session. Surveys contained quantitative and qualitative responses. Three years of evaluations were analyzed. A total of 451 (88 %) students completed the evaluations. Comments were thematically analyzed. Ninety-four percent agreed that the theater piece prompted reflection on patient-provider communications, and 89 % agreed that it stimulated discussion on complex issues with breaking bad news. The two most common themes in student comments concerned the importance of realism in the theater piece, and the value of experiencing multiple perspectives. Use of professional actors during the role play exercises enhances the realism and pushed the students out of their own "comfort zones" in ways that may more closely approximate real life clinical situations. Interactive theater can be a potentially powerful tool to teach breaking bad news during medical school.

  10. Various Stagings of Cankar’s Works at the Slovenian National Theater in Ljubljana and Other Slovenian Theaters in the Interwar Period (1918–1941

    Full Text Available Plays by Ivan Cankar unequivocally marked Slovenian theater in the period from 1918 to 1941. In addition to Shakespeare’s works, it was Cankar’s plays that were most frequently performed on the Slovenian stage. His works especially appealed to directors that were seeking deeper, symbolic meanings of the text, which they tried to present to the audience to the best of their ability. Thus, Cankar’s narrative was intensified through directing and acting, whereas the scenery was of secondary importance in most performances. These mostly included painted scenes or backdrops to represent the setting. Only the stagings of Pohujšanje v dolini Šentflorjanski (The Scandal in the St. Florian Valley, Kralj na Betajnovi (The King of Betajnova, Hlapec Jernej in njegova pravica (The Servant Jernej and His Justice, and Lepa Vida (The Beautiful Vida contained more developed scenography. However, until the 1930s, scenery design for Cankar’s plays performed on the professional stage varied between painted backdrops and expressionist sets. It was not until the appearance of the director and scenographer Bojan Stupica that the scenery of these plays reached the boundaries of new realism and modern avant-garde. Until then, an unspoken rule had been in force that the scenery of Cankar’s plays should not extend beyond the boundaries of expressionism. This rule was observed even by the avant-garde painter Avgust Černigoj. However, Cankar’s plays were staged completely differently in workers’ theaters and popular theaters. With new avant-garde staging, they often surpassed the development of theater design in professional theaters, and caught up with contemporary formal ideas in Slovenian and European fine arts. Here, Cankar’s works were staged as anti-political propaganda. In order to better express their new ideas, these theaters also used new tools, such as projectors and film clips, and experimented with spotlights. The most original among these

    Effect of grain refinements and amorphization by high-pressure torsion (HPT) on surface chemistry was investigated on TiNi. X-ray diffraction and micro-Vickers tests were used to check the phase changes and hardness before and after HPT. X-ray photoelectron spectroscopy was used to observe the changes in the natural passive film formation on the surface. Phase analysis reveals the change of crystalline TiNi to nanostructured one with increased hardness with straining by HPT. Grain refinement and amorphization caused by HPT reduce the amount of metallic Ni in the passive films and also increase the thickness of the film.

    Sputtered thin films of equiatomic TiNi and TiNiX ternary alloys have excellent mechanical properties and exhibit robust shape-memory and transformational superelasticity. Furthermore, the energetic nature of the sputter deposition process allows the creation of highly refined microstructures that are difficult to achieve by melt-solidification. The present paper will present recent work on the relationship between processing, microstructure and properties of binary TiNi thin films, focusing primarily on residual stresses, kinetics of stress-relaxation and crystallization, and fine grain sizes achievable using hot-substrate direct crystallization.

    The shape memory characteristics in TiNi alloys are greatly effected by the alloy composition and heat treatment condition. The present work was aimed to investigate the effect of Pd x (x=5,10,15,20) addition on the shape memory chracteristics of TiNi alloys by means of electrical resistance measurement. X-ray diffraction, differential scanning calorimetry and electron dispersive analysis X-ray measurement. The results obtained from this study are as follows; 1. The martensitic transformation start temperature, Ms of Ti-Ni 50-x -Pd x alloys decreased considerably with the increase of Pd content up to 10at%, whereas increased largely with the increase of Pd content in the alloys with Pd content more than 15at%. 2. The Ms temperature of Ti-Ni 50-x -Pd x alloys with cold working was significantly lower than that of the fully annealed alloys because high density dislocation has been introduced by the cold working which suppressed the martensitic transformation.

  17. Micromechanical Analysis of Crack Closure Mechanism for Intelligent Material Containing TiNi Fibers

    Araki, Shigetoshi; Ono, Hiroyuki; Saito, Kenji

    In our previous study, the micromechanical modeling of an intelligent material containing TiNi fibers was performed and the stress intensity factor KI at the tip of the crack in the material was expressed in terms of the magnitude of the shape memory shrinkage of the fibers and the thermal expansion strain in the material. In this study, the value of KI at the tip of the crack in the TiNi/epoxy material is calculated numerically by using analytical expressions obtained in our first report. As a result, we find that the KI value decreases with increasing shrink strain of the fibers, and this tendency agrees with that of the experimental result obtained by Shimamoto etal.(Trans. Jpn. Soc. Mech. Eng., Vol. 65, No. 634 (1999), pp. 1282-1286). Moreover, there exists an optimal value of the shrink strain of the fibers to make the KI value zero. The change in KI with temperature during the heating process from the reference temperature to the inverse austenitic finishing temperature of TiNi fiber is also consistent with the experimental result. These results can be explained by the changes in the shrink strain, the thermal expansion strain, and the elastic moduli of TiNi fiber with temperature. These results may be useful in designing intelligent materials containing TiNi fibers from the viewpoint of crack closure.

    This book is about change: in the Soviet Union, in Eastern Europe, and how we in the West should respond. Few observers of the international scene, even in their wildest dreams, could have imagined the course of events that have taken place in Europe since early 1989. The communist system came to a dead end. Old social, economic, political, and psychological recipes no longer were acceptable, either in the Soviet Union or in Eastern Europe. Soviet leadership had only two choices: repress change in Eastern Europe and demand continued sacrifices from its own people, or press forward on the road of economic reform and political restructuring at home and the pursuit of new relationships abroad. The three volumes on Alternative Conventional Defense Postures in the European Theater contributed significantly to the current debate in Europe and in the United States on the future of European security. As an outgrowth of a German-American workshop at the Army War College in Carlisle, Pennsylvania, the two editors have succeeded in bringing together statesmen, soldiers, and civilian defense specialist from the Federal Republic, the United States, and the Soviet Union, who represent a variety of schools of political and strategic thinking

    Full Text Available This article is a dialogue between two practitioners of Image theater—a technique which involves using the body to share stories. Working in Quebec and Scotland, we discuss the potential ways such a form of performative inquiry (FELS, 1998 can, through an online medium, be documented and disseminated in ways that are coherent with, and build on, the principles of interactive theater. Our hope is that such an exploration will enable the participants in the work, ourselves, and our readers as performative social science researchers, so that we may engage as spect-actors (BOAL, 1979 with the material and build communities of practice through reflection on action (praxis. A key aspect we consider is ways in which physical dialogue through the body evolves—first as a method of enacting the world, where collective meaning emerges and secondly, as a concept that uses symbolic/metaphoric aesthetic language through what one colleague calls "body-storming" (like "brain-storming," but with the emotional and sensory body as a source and language of expression.

    Full Text Available The reduction of risk behaviors in secondary schools is a key concern for parents, teachers, and school administrators. School is one of the primary contexts of socialization for young people; thus, the investment in school-based programs to reduce risk behaviors is essential. In this study, we report on youth who participated in an intervention designed to improve decision-making skills based on positive youth development approaches. We examine changes in decision-making skills before and after involvement in the Teen Interactive Theater Education (TITE program and retrospective self-assessment of change in knowledge, abilities, and beliefs as a result of participating in TITE (n = 127. Youth that reported increases in knowledge, abilities, and beliefs due to the intervention (n = 89 were more likely to think about the consequences of their decisions and list options before making a decision compared to their counterparts that reported less overall learning (n = 38. Implications for intervention research and stakeholders are discussed.

    Full Text Available Trypsin inhibitors are studied in a variety of models for their anti-obesity and anti-inflammatory bioactive properties. Our group has previously demonstrated the satietogenic effect of tamarind seed trypsin inhibitors (TTI in eutrophic mouse models and anti-inflammatory effects of other trypsin inhibitors. In this study, we evaluated TTI effect upon satiety, biochemical and inflammatory parameters in an experimental model of metabolic syndrome (MetS. Three groups of n = 5 male Wistar rats with obesity-based MetS received for 10 days one of the following: (1 Cafeteria diet; (2 Cafeteria diet + TTI (25 mg/kg; and (3 Standard diet. TTI reduced food intake in animals with MetS. Nevertheless, weight gain was not different between studied groups. Dyslipidemia parameters were not different with the use of TTI, only the group receiving standard diet showed lower very low density lipoprotein (VLDL and triglycerides (TG (Kruskal–Wallis, p < 0.05. Interleukin-6 (IL-6 production did not differ between groups. Interestingly, tumor necrosis factor-alpha (TNF-α was lower in animals receiving TTI. Our results corroborate the satietogenic effect of TTI in a MetS model. Furthermore, we showed that TTI added to a cafeteria diet may decrease inflammation regardless of weight loss. This puts TTI as a candidate for studies to test its effectiveness as an adjuvant in MetS treatment.

    Development of tamarind seed gum (TSG)-hydrolyzed polymethacrylamide-g-gellan (h-Pmaa-g-GG) composite beads for extended release of diclofenac sodium using 3 2 full factorial design is the main purpose of this study. The ratio of h-Pmaa-g-GG and TSG and concentration of cross-linker CaCl 2 were taken as independent factors with three different levels of each. Effects of polymer ratio and CaCl 2 on drug entrapment efficiency (DEE), drug release, bead size and swelling were investigated. Responses such as DEE and different drug release parameters were statistically analyzed by 3 2 full factorial design using Design-Expert software and finally the formulation factors were optimized to obtain USP-reference release profile. Drug release rate was found to decrease with decrease in the ratio of h-Pmaa-g-GG:TSG and increase in the concentration of Ca 2+ ions in cross-linking medium. The optimized formulation showed DEE of 93.25% and an extended drug release profile over a period of 10h with f 2 =80.13. Kinetic modeling unveiled case-I-Fickian diffusion based drug release mechanism. Copyright © 2018 Elsevier B.V. All rights reserved.

    Patho-physiologies related to skin are diverse in nature such as burns, skin ulcers, atopic dermatitis, psoriasis etc. which impose severe bio-medical problems and thus enforce requirement of new and healthy skin prepared through tissues engineering methodologies. However, fully functional and biodegradable matrix for attachment, growth, proliferation and differentiation of the relevant cells is not available. In the present study, we introduce a set of hydrogels synthesized by incorporation of a synthetic monomer (Hydroxyethlmethacryate) with a semi-synthetic polymer backbone (carboxy methyl tamarind, CMT) in different mole ratios. We termed these materials as CMT:HEMA based hydrogels and these were characterized by different physico-chemical techniques, namely by X-Ray Diffraction, SEM and Dynamic Light Scattering. Biocompatibility studies with HaCaT, NIH-3T3 and mouse dermal fibroblasts confirm that this material is biocompatible. MTT assay further confirmed that this material does not have any cytotoxic effects. Assays for mitochondrial functionality such as ATP assay and mitochondrial reactive oxygen (ROS) generation also suggest that this material is safe and does not have any cytotoxicity. Hemolytic assay with red blood cells and acute skin irritation test on SD Rats confirmed that this material is suitable for ex-vivo application in future. We suggest that this hydrogel is suitable for in-vivo applications and may have clinical and commercial importance against skin disorders. Copyright © 2018. Published by Elsevier Ltd.

    The preparation of tamarind fruit seed granular activated carbon (TSAC) by microwave induced chemical activation for the adsorptive treatment of semi-aerobic landfill leachate has been attempted. The chemical and physical properties of TSAC were examined. A series of column tests were performed to determine the breakthrough characteristics, by varying the operational parameters, hydraulic loading rate (5-20 mL/min) and adsorbent bed height (15-21 cm). Ammonical nitrogen and chemical oxygen demand (COD), which provide a prerequisite insight into the prediction of leachate quality was quantified. Results illustrated an encouraging performance for the adsorptive removal of ammonical nitrogen and COD, with the highest bed capacity of 84.69 and 55.09 mg/g respectively, at the hydraulic loading rate of 5 mL/min and adsorbent bed height of 21 cm. The dynamic adsorption behavior was satisfactory described by the Thomas and Yoon-Nelson models. The findings demonstrated the applicability of TSAC for the adsorptive treatment of landfill leachate.

    The study reports the synthesis and characterization of gelatin-tamarind gum (TG) based filled hydrogels for drug delivery applications. In this study, three different types of carbon nanotubes (CNTs) were incorporated within the dispersed TG phase of the filled hydrogels. The prepared hydrogels were thoroughly characterised using bright field microscope, FESEM, FTIR spectroscopy, differential scanning calorimeter, and mechanical tester. The swelling and the drug (salicylic acid) release properties of the filled hydrogels were also evaluated. The micrographs revealed the formation of biphasic systems. The internal phase appeared as agglomerates, and the CNTs were confined within the dispersed TG phase. FTIR and XRD studies revealed that CNTs promoted associative interactions among the components of the hydrogel, which promoted the formation of large crystallite size. The mechanical study indicated better resistance to the breakdown of the architecture of the CNT-containing filled hydrogels. Drug release studies, both passive and iontophoretic, suggested that the non-Fickian diffusion of the drug was prevalent during its release from hydrogel matrices. The prepared hydrogels were cytocompatible with human keratinocytes. The results suggested the probable use of such hydrogels in wound healing, tissue engineering and drug delivery applications.

    This study aims to explore the views of members of theater teams regarding the proposed introduction of a workplace-based assessment of nontechnical skills of surgeons (NOTSS) into the Intercollegiate Surgical Curriculum Programme in the United Kingdom. In addition, the previous training and familiarity of the members of the surgical theater team with the concept and assessment of NOTSS would be evaluated. A regional survey of members of theater teams (consultant surgeons, anesthetists, scrub nurses, and trainees) was performed at 1 teaching and 2 district general hospitals in South Yorkshire. There were 160 respondents corresponding to a response rate of 81%. The majority (77%) were not aware of the NOTSS assessment tool with only 9% of respondents reporting to have previously used the NOTSS tool and just 3% having received training in NOTSS assessment. Overall, 81% stated that assessing NOTSS was as important as assessing technical skills. Trainees attributed less importance to nontechnical skills than the other groups (p ≤ 0.016). Although opinion appears divided as to whether the presence of a consultant surgeon in theater could potentially make it difficult to assess a trainee's leadership skills and decision-making capabilities, overall 60% agree that the routine use of NOTSS assessment would enhance safety in the operating theater and 80% agree that the NOTSS tool should be introduced to assess the nontechnical skills of trainees in theater. However, a significantly lower proportion of trainees (45%) agreed on the latter compared with the other groups (p = 0.001). Our survey demonstrates acceptability among the theater team for the introduction of the NOTSS tool into the surgical curriculum. However, lack of familiarity highlights the importance of faculty training for assessors before such an introduction. Copyright © 2015 Association of Program Directors in Surgery.

    Full Text Available The article examines “theater” as a cultural and artistic universal that served as a means ofThe article examines “theater” as a cultural and artistic universal that served as a means of developing mindset and self-identity of the Austrian literary group “Young Vienna” at the thth turn of the 19 and 20 centuries. Theater as a metaphor of the human life becomes integral part of the poetics in the works of the group members. The essay examines ideas and fictional worlds of the writers belonging to the group against the context of their contemporary culture. It touches upon Russian perception of the aesthetics of Viennese theater (A. Block, A.J. Tairov and involves retrospective evidences and reflections of Austrian authors (Stefan thth weig, G. Broch on Vienna at the turn of the 19 and 20centuries. As soon as Habsburgs’ empire loses its political positions, the theatrical illusion becomes more and more important. Yet it is the “Young Vienna” that makes the idea of the theater all-pervading: this concept includes both the motif of hopeless masquerade (Schnitzler and the motif of liberation from the false play of masks (Hofmannsthal. According to the concept of the group’s mastermind H. Bahr, the theater played essential role in the spiritual and aesthetic integration of Austria. References to the mystery genre, the street theater, the puppet theater may be traced in the plays written by the members of the group. Austrian authors reconstructed folk plays that enabled the mactualize primordial theatrical forms and inspired them to subtly play with these forms. For the “Young Vienna” group, theater becomes a projection of doubts and misgivings of their time. In place of a jaded actor, there comes a person without a mask who appears at once unprotected and open to acquire his or her “true” face.

    In this study, cavitation erosion tests were carried out by using thermal spraying and deposition of Ti-Ni shape memory alloy for the surface coating. The results show the test speciment of Ti-Ni thermal spraying has many initial defects, so that the erosion resistance is very low. The erosion resistance of Ti-Ni deposit is about 5-10 times higher than that of SUS 304, thus erosion resistance of Ti-Ni deposit is better than that of Ti-Ni thermal spraying. The cavitation erosion tests were carried out by using Fe-Mn-Si with shape memory and gunmetal with low elastic modulus. The erosion resistance of Fe-Mn-Si shape memory alloy solid is about 9 times higher than that of SUS 304. The erosion resistance of gunmetal is almost the same as SUS 304, because the test specimen of gunmetal has many small defects on the original surface. (author)

    Apolonio B. Chua

    2007-06-01

    Full Text Available The study focuses on Jose Rizal’s participation in Philippine Theater during the last decades of the nineteenth century. It starts with a careful inventory of attitudes towards existing theater forms and a description of the culture of theater as conceived and imagined in Rizal’s Noli Me Tangere (1887 and El Filibusterismo (1891. In Chapter 20: “The Town Council’s Meeting” in Noli Me Tangere, the study zooms in on the debate on what would be the best and most appropriate theatre piece for the town fiesta. Here, Rizal delineates theater enmeshed in issues of power and Spanish colonialism. He notes as significant the ilustrados’ claim to theatre space and ideology, thereby interrogating Spanish hegemony. The debate becomes the central imagery and situation for Rizal’s analysis and construction of the history of Philippine theater in the novel. Conservative and radical elements duel. The conflict becomes sharper as Rizal continues his critique by putting into his fictional world the very historical actors known at that time; namely, Nemesio Ratia, Jose Carvajal and Praxedes Julia Fernandez (also known as “Yeyeng”. They were part of the comedia troupe hired by the town for the fiesta. In Rizal’s second novel, El Filibusterismo, we encounter the events surrounding the presentation by a French opera troupe in Teatro de Variedades, which Rizal considers as the Manila theater model. The features of this model include a particular ticket system, various kinds of audiences, imported dramatic texts which were largely incomprehensible, actors behaving as actors both on-stage and off-stage, and the Teatro de Variedades space as stage for seizure or possession of power. When the students in the audience stage a walk-out in the theatre of the city and when in provincial San Diego, a stampede cuts short a comedia performance, the interrelationships between society and a discourse of power are revealed.Rizal’s annotations of Philippine

    Cho, H.; Kim, H.Y.; Miyazaki, S.

    2006-01-01

    Alloying process of a Ti/Ni multilayer thin film was investigated in detail by differential scanning calorimetry (DSC), X-ray diffractometry (XRD) and transmission electron microscopy (TEM). The Ti/Ni multilayer thin film was prepared by depositing Ti and Ni layers alternately on a SiO 2 /Si substrate. The number of each metal layer was 100, and the total thickness was 3 μm. The alloy composition was determined as Ti-51 at.%Ni by electron probe micro analysis (EPMA). The DSC curve exhibited three exothermic peaks at 621, 680 and 701 K during heating the as-sputtered multilayer thin film. In order to investigate the alloying process, XRD and TEM observation was carried out for the specimens heated up to various temperatures with the heating rate same as the DSC measurement. The XRD profile of the as-sputtered film revealed only diffraction peaks of Ti and Ni. But reaction layers of 3 nm in thickness were observed at the interfaces of Ti and Ni layers in cross-sectional TEM images. The reaction layer was confirmed as an amorphous phase by the nano beam diffraction analysis. The XRD profiles exhibited that the intensity of Ti diffraction peak decreased in the specimen heat-treated above 600 K. The peak from Ni became broad and shifted to lower diffraction angle. The amorphous layer thickened up to 6 nm in the specimen heated up to 640 K. The diffraction peak corresponding to Ti-Ni B2 phase appeared and the peak from Ni disappeared for the specimen heated up to 675 K. The Ti-Ni B2 crystallized from the amorphous reaction layer. After further heating above the third exothermic peak, the intensity of the peak from the Ti-Ni B2 phase increased, the peak from Ti disappeared and the peaks corresponding to Ti 2 Ni appeared. The Ti 2 Ni phase was formed by the reaction of the Ti-Ni B2 and Ti

    Singing styles in Musical Theater singing might differ in many ways from Western Classical singing. However, vocal tract adjustments are not understood in detail. Vocal tract shapes of a single professional Music Theater female subject were analyzed concerning different aspects of singing styles using dynamic real-time magnetic resonance imaging technology with a frame rate of 8 fps. The different tasks include register differences, belting, and vibrato strategies. Articulatory differences were found between head register, modal register, and belting. Also, some vibrato strategies ("jazzy" vibrato) do involve vocal tract adjustments, whereas others (classical vibrato) do not. Vocal tract shaping might contribute to the establishment of different singing functions in Musical Theater singing. Copyright © 2014 The Voice Foundation. Published by Elsevier Inc.

  20. Street Theater and Subject Formation in Wartime China: Toward a New Form of Public Art

    Directory of Open Access Journals (Sweden)

    Xiaobing Tang

    2016-03-01

    Full Text Available Based on archival research, this article presents a succinct history of the street theater movement in China through the 1930s. It examines how complex discourses and competing visions, as well as historical events and practices—in particular the War of Resistance against Japan—both shaped and propelled the movement. The author focuses on theoretical and practical issues that promoters and practitioners of street theater dealt with and reflected on in three succeeding stages. Observing that the street theater movement hastened the formation of a modern national imagination, the author argues that the movement presented a paradigmatic development as it foregrounded the imperative to engage rural China as well as the need for participants to acquire new subject positions.

    A comparative study of the solid-state reaction (SSR) in a series of Ti/Ni multilayered films (MLDs) with bilayer periods of 0.65-22.2 nm and a constant Ti to Ni sublayer thickness ratio was performed by using experimental and computer-simulated magneto-optical (MO) spectroscopy based on different models of MLFs, as well as x-ray diffraction (XRD). The spectral and sublayer thickness dependences of the MO properties of the Ti/Ni MLFs were explained on the basis of the electromagnetic theory. The existence of a threshold nominal Ni-sublayer thickness of about 3 nm for the as-deposited Ti/Ni MLF to observe of the equatorial Kerr effect was explained by a solid-state reaction which formed nonmagnetic alloyed regions between pure components during the MLF deposition. The SSR in the Ti/Ni MLFs, which was caused by the low temperature annealing, led to the formation of an amorphous Ti-Ni alloy and took place mainly in the Ti/Ni MLFs with ''thick'' sublayers. For the caes of Ti/Ni MLFs, the MO approach turned out to...

  2. Detection of tiny amounts of fissile materials in large-sized containers with radioactive waste

    2018-01-01

    The paper is devoted to non-destructive control of tiny amounts of fissile materials in large-sized containers filled with radioactive waste (RAW). The aim of this work is to model an active neutron interrogation facility for detection of fissile ma-terials inside NZK type containers with RAW and determine the minimal detectable mass of U-235 as a function of various param-eters: matrix type, nonuniformity of container filling, neutron gen-erator parameters (flux, pulse frequency, pulse duration), meas-urement time. As a result the dependence of minimal detectable mass on fissile materials location inside container is shown. Nonu-niformity of the thermal neutron flux inside a container is the main reason of the space-heterogeneity of minimal detectable mass in-side a large-sized container. Our experiments with tiny amounts of uranium-235 (<1 g) confirm the detection of fissile materials in NZK containers by using active neutron interrogation technique.

  3. Limitations of constitutive relations for TiNi shape memory alloys

    International Nuclear Information System (INIS)

    Tang, W.; Sandstroem, R.

    1995-01-01

    Phase transformation tensor Ω in the constitutive equation proposed by Tanaka has been evaluated by employing experimental data of TiNi alloys in a constrained recovery process. It demonstrates that the absolute value of Ω for the constrained recovery process is typically about 0.6 ∼ 0.7 x 10 3 MPa, which is much smaller than that for the stress - induced martensitic transformation (typically 2.5 ∼ 3.5 x 10 3 ). Based on the evaluated results for Ω, predicted recovery stress - temperature relations by the constitutive equation are compared with the experimental data for TiNi rods under different strains. Big discrepancy exists for large strain conditions. Several transformation kinetic expressions are examined for the constitutive relation of the constrained recovery process. (orig.)

    Carlos Augusto do N. Oliveira

    2013-01-01

    Full Text Available The development of shape memory actuators has enabled noteworthy applications in the mechanical engineering, robotics, aerospace, and oil industries and in medicine. These applications have been targeted on miniaturization and taking full advantage of spaces. This article analyses a Ti-Ni shape memory actuator used as part of a flow control system. A Ti-Ni spring actuator is subjected to thermomechanical training and parameters such as transformation temperature, thermal hysteresis and shape memory effect performance were investigated. These parameters were important for understanding the behavior of the actuator related to martensitic phase transformation during the heating and cooling cycles which it undergoes when in service. The multiple regression methodology was used as a computational tool for analysing data in order to simulate and predict the results for stress and cycles where the experimental data was not developed. The results obtained using the training cycles enable actuators to be characterized and the numerical simulation to be validated.

    We describe a track segment recognition scheme called the Tiny Triplet Finder (TTF) that involves grouping of three hits satisfying a constraint such as forming of a straight line. The TTF performs this O(n 3 ) function in O(n) time, where n is number of hits in each detector plane. The word ''tiny'' reflects the fact that the FPGA resource usage is small. The number of logic elements needed for the TTF is O(Nlog(N)), where N is the number of bins in the coordinate considered, which for large N, is significantly smaller than O(N 2 ) needed for typical implementations of similar functions. The TTF is also suitable for software implementations as well as many other pattern recognition problems

    2012-09-01

    Full Text Available Strategic marketing instruments such as segmentation and targeting can benefit performing arts institutions and render their offer more competitive. To segment classical performing arts audiences, however, the traditionally used variable is social class. In this paper, it is argued that such often suggested traditional segmentation criteria can prove to be context-insensitive and as such cannot be applied invariably across different settings. Based on an analysis of Czech National Theater audiences and its motivations, we propose the sought benefit of the theater visit as an alternative segmentation basis that may prove to be more context-sensitive.

    Highlights: • Ultra-low ambient energy was scavenged to power the first of its kind wireless corrosion sensors. • Three feasible tiny-energy sources were exploited for long-term corrosion monitoring. • Automatic recharging control of heterogeneous tiny energy was proposed for human-free monitoring. • Corrosion itself was applied as an energy source to power the wireless corrosion-monitoring motes. - Abstract: Reinforcing steel corrosion is a significant factor leading to the durability deterioration of reinforced concrete (RC) structures. The on-line monitoring of the corrosion of RC structures in a long-term, human-free manner is not only valuable in industry, but also a significant challenge in academia. This paper presents the first of its kind corrosion-monitoring approach that only exploits three heterogeneous tiny energy sources to power commercial-off-the-shelf wireless sensor motes such that the corrosion-related data are automatically and autonomously captured and sent to users via wireless channels. We first investigated the availability of these three tiny energy sources: corrosion energy, a cement battery, and a weak solar energy. In particular, the two former energy sources inherently exist in RC structures and can be generated continually in the service-life of RC structures, which beneficial for the prospects of long-term corrosion monitoring. We then proposed a proof-of-concept prototype, which consisted of a Telosb wireless sensor mote and an energy harvester in order to evaluate the feasibility and effectiveness of the ultralow-power ambient energy as a type of power supply in corrosion monitoring applications. The critical metrics for the holographic monitoring of RC structures, including electrochemical noise, humidity and temperature, were successfully acquired and analysed using a post-processing program. This paper describes a unique and novel approach towards the realisation of smart structural monitoring and control system in the

    Highlights: ► We developed a sputtering deposition process equipped with an ion irradiation system. ► Ion irradiation enables crystallization at lower substrate temperature. ► Ion fluence has an effective range for low-temperature crystallization. ► Crystallized films made on polyimide by the process show the shape memory effect. -- Abstract: TiNi is well known as a typical shape-memory alloy, and the shape-memory property appears only when the structure is crystalline. Until recently, the material has been formed as amorphous film by single-target sputtering deposition at first and then crystallized by being annealed at high temperature over 500 °C. Therefore, it has been difficult to make crystalline TiNi film directly on a substrate of polymer-based material because of the low heat resistance of substrate. In order to realize an actuator from the crystallized TiNi film on polymer substrates, the substrate temperature should be kept below 200 °C throughout the whole process. In our previous studies we have found that deposited film can be crystallized at very low temperature without annealing but with simultaneous irradiation of Ar ions during sputter-deposition. And we have also demonstrated the shape-memory effect with the TiNi film made by the new process. In order to investigate what parameters of the process contribute to the low-temperature crystallization, we have focused to the ion fluence of the ion irradiation. Resultantly, it was found that the transition from amorphous structure to crystal one has a threshold range of ion fluence

    The present study deals with the development of novel pH-sensitive tamarind seed polysaccharide (TSP)-alginate composite beads for controlled diclofenac sodium delivery using response surface methodology by full 3(2) factorial design. The effect of polymer-blend ratio (sodium alginate:TSP) and cross-linker (CaCl(2)) concentration on the drug encapsulation efficiency (DEE, %) and drug release from diclofenac sodium loaded TSP-alginate composite beads prepared by ionotropic gelation was optimized. The observed responses were coincided well with the predicted values by the experimental design. The DEE (%) of these beads containing diclofenac sodium was within the range between 72.23±2.14 and 97.32±4.03% with sustained in vitro drug release (69.08±2.36-96.07±3.54% in 10 h). The in vitro drug release from TSP-alginate composite beads containing diclofenac sodium was followed by controlled-release pattern (zero-order kinetics) with case-II transport mechanism. Particle size range of these beads was 0.71±0.03-1.33±0.04 mm. The swelling and degradation of the developed beads were influenced by different pH of the test medium. The FTIR and NMR analyses confirmed the compatibility of the diclofenac sodium with TSP and sodium alginate used to prepare the diclofenac sodium loaded TSP-alginate composite beads. The newly developed TSP-alginate composite beads are suitable for controlled delivery of diclofenac sodium for prolonged period. Copyright © 2011 Elsevier B.V. All rights reserved.

    In recent years, pre-strained TiNi shape memory alloys (SMA) have been used for fabricating smart structure with carbon fibers reinforced plastics (CFRP) in order to suppress microscopic mechanical damages. However, since the cure temperature of CFRP is higher than the reverse transformation temperatures of TiNi SMA, special fixture jigs have to be used for keeping the pre-strain during fabrication, which restricted its practical application. In order to overcome this difficulty, we developed a new method to fabricate SMA/CFRP smart composites without using special fixture jigs by controlling the transformation temperatures of SMA during fabrication. This method consists of using heavily cold-worked wires to increase the reverse transformation temperatures, and of using flash electrical heating of the wires after fabrication in order to decrease the reverse transformation temperatures to a lower temperature range again without damaging the epoxy resin around SMA wires. By choosing proper cold-working rate and composition of TiNi alloys, the reverse transformation temperatures were well controlled, and the TiNi/CFRP hybrid smart composite was fabricated without using special fixture jigs. The damage suppressing effect of cold drawn wires embedded in CFRP was confirmed.

    Effect of high-pressure torsion (HPT) deformation on biocompatibility and surface chemistry of TiNi was systematically investigated. Ti–50 mol% Ni was subjected to HPT straining for different numbers of turns, N = 0.25, 0.5, 1, 5 and 10 at a rotation speed of 1 rpm. X-ray photoelectron spectroscopy observations after 7 days of cell culture revealed the changes in the surface oxide composition, enrichment of Ti and detection of nitrogen derived from organic molecules in the culture medium. Plating efficiency of L929 cells was slightly increased by HPT deformation though no significant difference was observed. Albumin adsorption was higher in HPT-deformed samples, while vitronectin adsorption was peaked at N = 1. HPT deformation was also found to effectively suppress the Ni ion release from the TiNi samples into the cell culture medium even after the low degree of deformation at N = 0.25. - Highlights: • Nanostructured Ti–50 mol%Ni alloy was produced using high-pressure torsion. • HPT deformation improved L929 growth on TiNi samples. • Changes in surface chemistry were observed in HPT deformed samples. • Protein adsorption behavior was influenced by the surface chemistry. • Ni ion release was suppressed in HPT deformed samples.

  17. THE ROLE OF TINY GRAINS ON THE ACCRETION PROCESS IN PROTOPLANETARY DISKS

    International Nuclear Information System (INIS)

    2011-01-01

    Tiny grains such as polycyclic aromatic hydrocarbons (PAHs) have been thought to dramatically reduce the coupling between the gas and magnetic fields in weakly ionized gas such as in protoplanetary disks (PPDs) because they provide a tremendous surface area to recombine free electrons. The presence of tiny grains in PPDs thus raises the question of whether the magnetorotational instability (MRI) is able to drive rapid accretion consistent with observations. Charged tiny grains have similar conduction properties as ions, whose presence leads to qualitatively new behaviors in the conductivity tensor, characterized by n-bar /n e >1, where n e and n-bar denote the number densities of free electrons and all other charged species, respectively. In particular, Ohmic conductivity becomes dominated by charged grains rather than by electrons when n-bar /n e exceeds about 10 3 , and Hall and ambipolar diffusion (AD) coefficients are reduced by a factor of ( n-bar /n e ) 2 in the AD-dominated regime relative to that in the Ohmic regime. Applying the methodology of Bai, we find that in PPDs, when PAHs are sufficiently abundant (∼> 10 -9 per H 2 molecule), there exists a transition radius r trans of about 10-20 AU, beyond which the MRI active layer extends to the disk midplane. At r trans , the optimistically predicted MRI-driven accretion rate M-dot is one to two orders of magnitude smaller than that in the grain-free case, which is too small compared with the observed rates, but is in general no smaller than the predicted M-dot with solar-abundance 0.1 μm grains. At r > r trans , we find that, remarkably, the predicted M-dot exceeds the grain-free case due to a net reduction of AD by charged tiny grains and reaches a few times 10 -8 M sun yr -1 . This is sufficient to account for the observed M-dot in transitional disks. Larger grains (∼> 0.1 μm) are too massive to reach such high abundance as tiny grains and to facilitate the accretion process.

  2. Judge upholds closing of theater that was site of high-risk sex.

    1995-05-05

    New York City's decision to close a gay movie theater where inspectors found male patrons engaging in unsafe sexual activity with other men was upheld by Justice Marilyn G. Diamond of the Supreme Court in Manhattan. She rejected the theater owner's argument that the city's March 31, 1995 closure of the New David Cinema on West 54th Street violated the Constitution's guarantee of freedom of speech. The city based its action on a provision in the state health code which prohibits oral, anal or vaginal sex in commercial establishments. Despite several warnings from the city, the movie house did not follow the demands that it move forcefully to prevent high-risk sexual activity among patrons. The New David was one of two theaters and one sex club shut down by the Health Department in recent weeks, but the only one still closed at press time. Some gay activists contend the action was unjustified, since most of the sex that occurs in those establishments in consensual and involves solo or mutual masturbation. Others point out that a good deal of unsafe sex does occur. Because men often have several sexual liaisons during a single night at a theater or club, the risk of HIV transmission is magnified many-fold.

    Theater, music, dance, the literary and the visual arts can convey the joys and controversies of science. We describe a program at the Graduate Center entitled Science & the Arts which is designed to communicate to the public the excitement and wonder of science, technology, engineering and mathematics. Over the past few years there have been major successes in communicating science to the public through the arts. This is especially evident in theater, film and opera with such recent plays as Copenhagen, the Oscar winning film A Beautiful Mind and the opera Doctor Atomic at the Met. The performance series Science & the Arts has been developed and tested at the Graduate Center of the City University of New York (CUNY) in mid-Manhattan for more than nine years, see http://web.gc.cuny.edu/sciart/ . We have established working relationships with actors, playwrights, dancers, choreographers, musicians, composers, artists and scientists who work at the intersection of science and the arts. In this presentation we will illustrate many of our collaborations in theater, dance, music and art. Faculty members, professionals and students from the university, other educational institutions, museums, theaters and government laboratories as well as the public with an interest science and arts programs should find this presentation of particular interest.

    Diabetes treatment involves a demanding self-management regime that is particularly challenging to adolescents. There is a need for qualitative research into the specific contexts in which adolescents attempt to balance self-management demands with the needs and desires of adolescent life. This study investigates the usefulness of image theater, a participatory form of theater using the body as an expressive tool, to articulate these dilemmas in daily life contexts. We performed a qualitative analysis of two image theater workshops with 12- to 18-year-old adolescents living with diabetes. Our results show three areas of application: (a) unraveling the contextual complexity of lived experience, (b) the articulation of implicit understandings and underlying motives, and (c) the playful exploration of new behavior. We conclude that image theater is a promising method, especially with respect to the opportunities of a more contextual and action-oriented understanding of the trade-offs made in self-management provide for diabetes education and counseling.

    High temperature annealing effect on structural and magnetic properties of Ti/Ni multilayer (ML) up to 600 deg. C have been studied and reported in this paper. Ti/Ni multilayer samples having constant layer thicknesses of 50 A each are deposited on float glass and Si(1 1 1) substrates using electron-beam evaporation technique under ultra-high vacuum (UHV) conditions at room temperatures. The micro-structural parameters and their evolution with temperature for as-deposited as well as annealed multilayer samples up to 600 deg. C in a step of 100 deg. C for 1 h are determined by using X-ray diffraction (XRD) and grazing incidence X-ray reflectivity techniques. The X-ray diffraction pattern recorded at 300 deg. C annealed multilayer sample shows interesting structural transformation (from crystalline to amorphous) because of the solid-state reaction (SSR) and subsequent re-crystallization at higher temperatures of annealing, particularly at ≥400 deg. C due to the formation of TiNi 3 and Ti 2 Ni alloy phases. Sample quality and surface morphology are examined by using atomic force microscopy (AFM) technique for both as-deposited as well as annealed multilayer samples. In addition to this, a temperature dependent dc resistivity measurement is also used to study the structural transformation and subsequent alloy phase formation due to annealing treatment. The corresponding magnetization behavior of multilayer samples after each stage of annealing has been investigated by using Magneto-Optical Kerr Effect (MOKE) technique and results are interpreted in terms of observed micro-structural changes

  15. Effects of Surface Dipole Lengths on Evaporation of Tiny Water Aggregation

    2013-01-01

    Using molecular dynamics simulation, we compared evaporation behavior of a tiny amount of water molecules adsorbed on solid surfaces with different dipole lengths, including surface dipole lengths of 1 fold, 2 folds, 4 folds, 6 folds and 8 folds of 0.14 nm and different charges from 0.1e to 0.9e. Surfaces with short dipole lengths (1-fold system) can always maintain hydrophobic character and the evaporation speeds are not influenced, whether the surface charges are enhanced or weakened; but when surface dipole lengths get to 8 folds, surfaces become more hydrophilic as the surface charge increases, and the evaporation speeds increase gradually and monotonically. By tuning dipole lengths from 1-fold to 8-fold systems, we confirmed non-monotonic variation of the evaporation flux (first increases, then decreases) in 4 fold system with charges (0.1e–0.7e), reported in our previous paper [S. Wang, et al., J. Phys. Chem. B 116 (2012) 13863], and also show the process from the enhancement of this unexpected non-monotonic variation to its vanishment with surface dipole lengths increasing. Herein, we demonstrated two key factors to influence the evaporation flux of a tiny amount of water molecules adsorbed on solid surfaces: the exposed surficial area of water aggregation from where the water molecules can evaporate directly and the attraction potential from the substrate hindering the evaporation. In addition, more interestingly, we showed extra steric effect of surface dipoles on further increase of evaporation flux for 2-folds, 4-folds, 6-folds and 8-folds systems with charges around larger than 0.7e. (The steric effect is first reported by parts of our authors [C. Wang, et al., Sci. Rep. 2 (2012) 358]). This study presents a complete physical picture of the influence of surface dipole lengths on the evaporation behavior of the adsorbed tiny amount of water.

    Purpose: Tiny intracranial aneurysms pose a significant therapeutic challenge for interventional neuroradiologists. The authors report their preliminary results of endovascular treatment of these aneurysms. Methods: Between January 2002 and December 2009, 52 tiny intracranial aneurysms (defined as ≤3 mm in maximum diameter) in 46 patients (22 men; mean age, 57.9 years) were treated by endosaccular coil embolisation or sole stent deployment in the parent artery. Of 52 aneurysms, 29 had ruptured and 23 remained unruptured. The initial angiographic results, procedural complications, and clinical outcomes were assessed at discharge. Imaging follow-up was performed with cerebral angiography. Results: One aneurysm coiling procedure failed because of unsuccessful micro-catheterization. Forty-three aneurysms were successfully coil embolized, of which complete occlusion was obtained in 14, subtotal occlusion in 18 and incomplete occlusion in 11. The other 8 aneurysms were treated by sole stent deployment in the parent artery. Procedural complications (2 intraprocedural ruptures and 3 thromboembolic events) occurred in 5 (9.6%) of 52 aneurysms, resulting in permanent morbidity in only 1 (2.2%, 1/46) patient. No rebleeding occurred during clinical follow-up (mean duration, 46.7 months). Of the 16 coiled aneurysms that receiving repetitive angiography, 6 initially completely and 3 subtotally occluded aneurysms remained unchanged, 4 initially subtotally and 3 incompletely occluded aneurysms progressed to total occlusion. Five sole stent deployed aneurysms received angiographic follow-up (mean duration, 10.0 months), of which 3 remained unchanged, 1 became smaller and 1 progressed to total occlusion. Conclusion: Endovascular treatment of tiny intracranial aneurysms is technical feasible and relatively safe. Coil embolisation seems to be effective in preventing early recanalisation, whereas sole stenting technique needs further investigation to determine its effectiveness.

    The aim of this presentation is to analyse and discuss some recent advances in shape memory and pseudoelastic properties of different alloys. Experimental work in connection with theoretical ones will be reviewed. The first part is devoted to the microstructural origin of shape memory properties of Fe-Mn-Si based alloys (γ-ε transformation); the second part is a synthetic analysis of the effects of thermomechanical treatments on shape memory and pseudoelastic effects in Ti-Ni alloys, with some focus on the behaviour of the R phase introduced.

    The temperature-dependent refractive index of zinc telluride film can be used to develop a tiny, low cost and film-coated optical fiber temperature sensor. Pulse reference-based compensation technique is used to largely reduce the background noise which makes it possible to detect the minor reflectivity change of the film in different temperatures. The temperature sensitivity is 0.0034dB/° and the background noise is measured to be 0.0005dB, so the resolution can achieve 0.2°.

    The mechanical properties of binary near equiatomic TiNi shape memory alloys were investigated after different types of mechanical and heat treatments. The changes of deformation behaviour are explained on the basis of substructure differences after work hardening. The ''elastic moduli'' of both the high-temperature phase B2 and the martensite B19' as well as the ''easy stage of deformation'' are dependent on the work hardening intensity and these changes are related to the mobility of B2/B19' interfaces. The martensite changes its morphology after work hardening. In contrast to a twinned martensite, typical for annealed alloys, the internally slipped martensite was detected after work hardening.

    Titanium-nickel thin films have been deposited on float glass substrates by ion beam sputtering in 100% pure argon atmosphere. Sputtering is predominant at energy region of incident ions, 1000 eV to 100 keV. The as-deposited films were investigated by X-ray photoelectron spectroscopy (XPS) and atomic force microscope (AFM). In this paper we attempted to study the surface morphology and elemental composition through AFM and XPS, respectively. Core level as well as valence band spectra of ion-beam sputtered Ti-Ni thin films at various Ar gas rates (5, 7 and 12 sccm) show that the thin film deposited at 3 sccm possess two distinct peaks at binding energies 458.55 eV and 464.36 eV mainly due to TiO 2 . Upon increasing Ar rate oxidation of Ti-Ni is reduced and the Ti-2p peaks begin approaching those of pure elemental Ti. Here Ti-2p peaks are observed at binding energy positions of 454.7 eV and 460.5 eV. AFM results show that the average grain size and roughness decrease, upon increasing Ar gas rate, from 2.90 μm to 0.096 μm and from 16.285 nm to 1.169 nm, respectively

    Ti-Ni shape memory alloy thin films were deposited using an RF magnetron sputtering apparatus. The as-sputtered films were heat-treated in order to crystallize and memorize. After the heat treatment, the shape memory characteristics have been investigated using DSC and thermomechanical tests. Upon cooling the thin films, the solution-treated films showed a single peak in the DSC curve indicating a single stage transformation occurring from B2 to the martensitic phase, while the age-treated films showed double peaks indicating a two-stage transformation, i.e., from B2 to the R-phase, then to the martensitic phase. A perfect shape memory effect was achieved in these sputter-deposited Ti-Ni thin films in association both with the R-phase and martensitic transformations. Transformation temperatures increased linearly with increasing applied stress. The transformation strain also increased with increasing stress. The shape memory characteristics were strongly affected by heat-treatment conditions. (author)

    Full Text Available The paper is devoted to non-destructive control of tiny amounts of fissile materials in large-sized containers filled with radioactive waste (RAW. The aim of this work is to model an active neutron interrogation facility for detection of fissile ma-terials inside NZK type containers with RAW and determine the minimal detectable mass of U-235 as a function of various param-eters: matrix type, nonuniformity of container filling, neutron gen-erator parameters (flux, pulse frequency, pulse duration, meas-urement time. As a result the dependence of minimal detectable mass on fissile materials location inside container is shown. Nonu-niformity of the thermal neutron flux inside a container is the main reason of the space-heterogeneity of minimal detectable mass in-side a large-sized container. Our experiments with tiny amounts of uranium-235 (<1 g confirm the detection of fissile materials in NZK containers by using active neutron interrogation technique.

    Ti-Ni shape memory alloy (SMA) thin films are very attractive material for industrial and medical applications such as micro-actuator, micro-sensors, and stents for blood vessels. An important property besides shape memory effect in the application of SMA thin films is the adhesion between the film and the substrate. When using thin films as micro-actuators or micro-sensors in MEMS, the film must be strongly adhered to the substrate. On the other hand, when using SMA thin films in medical devices such as stents, the deposited alloy thin film must be easily separable from the substrate for efficient processing. In this study, we investigated the effect of substrate roughness on the adhesion of Ti-Ni SMA thin films, as well as the structural properties and phase-transformation behavior of the fabricated films. Ti-Ni SMA thin films were deposited onto etched glass substrates with magnetron sputtering. Radio frequency plasma was used for etching the substrate. The adhesion properties were investigated through progressive scratch test. Structural properties of the films were determined via Feld emission scanning electron microscopy, X-ray diffraction measurements (XRD) and Energy-dispersive X-ray spectroscopy analysis. Phase transformation behaviors were observed with differential scanning calorimetry and low temperature-XRD. Ti-Ni SMA thin film deposited onto rough substrate provides higher adhesive strength than smooth substrate. However the roughness of the substrate has no influence on the growth and crystallization of the Ti-Ni SMA thin films.

    Full Text Available From 1948 to 2007, the academic community produced about a hundred titles of theses and dissertations on drama and theater, or made use of data from drama and theater for larger spheres of studies. The current article looked into identifying trends and points of emphasis, as the researches and studies progressed through roughly half a century of research production in the academic setting. Inductive in approach and tentative and exploratory in its analysis, the study identified four trends and points of emphasis in research production. In the fifties and sixties, the emphasis was more on studying the play text or drama; studies veered towards a literary reading and orientation. Eventually, this trend gave way to studying the larger phenomenon of mounting, and the mise en scéne and the spectator became additional units of concern for research. Studies began to have sections on props, costumes, and staging techniques. In the eighties, a larger concern for looking at theater as social production followed. Participant observation, field work and ethnography gave equal emphasis on the social context of theater. Marxism and other perspectives from the social sciences framed theater studies then; correlations between theater and society became useful. Towards the last decade of the century, theater studies aimed at a more conceptual approach, emphasizing core concepts like panata and other related or equivalent terms, elevating and defining the study of theater as a study of culture itself.

    Full Text Available We describe a teaching strategy, namely, the Great Theater of Physics, which stages a series of eight nontrivial demonstrations in the areas of mechanics, electricity, magnetism and waves. The aim was to generate feelings and attitudes that would promote the learning of physics, and to explore the motivation of Chemistry and Biology students towards classes in physics. The strategy was applied with a group of new students in Physics and Mathematics at the Faculty of Sciences at the Universidad Central de Venezuela. The method used was exploratory-descriptive.  Information was collected using a questionnaire with closed questions. In general, students from Physics and Mathematics disciplines experienced a significant increase in positive feelings towards physics after attending the theater; and negative feelings decreased, though not significantly. A greater percentage of women than men experienced an increase in positive feelings, though men experienced more intense positive feelings. This was not the case for negative feelings.

    Full Text Available The article deals with the issues of artwork impact on ballet artists’ and ballet masters’ creativity – creation of choreographic works based on artworks. Facts (examples demonstrating such borrowing are involved, but more significantly, the range of potential opportunities, which may enrich modern ballet theater, is outlined. The matter of figurative material takes on particular importance, i.e. the issue to what extent a choreographic work reflects the essence of an artwork accurately, deeply, and adequately. The article considers the connection and mutual benefit of the processes of creative interpenetration of graphics, art, sculpture, arts and crafts, and ballet theater. Different techniques of figurative sources are studied: illustration, statement, demonstration, comparison, event localization, generalization, stylistic device, and their visualization by means of choreographic dynamics. It’s concluded the synthetic nature of ballet theatergives rise to new polygenre structures that can intensify both expressive and semantic content of choreographic image, create original stage solutions.

    Full Text Available Dance, music, and oral narratives are an important and vibrant part of cultural practice and heritage in Timor-Leste. But while Timorese people have used such creative methods and processes during rituals, celebrations, and their fight for independence, today arts and artistic expression become an increasingly popular strategy in development cooperation. Especially diff erent forms of so-called participatory theater with origins in development cooperation, arts, and social movements, present themselves as innovative, participatory, and well applicable in terms of capacity building and stimulating positive social transformation. Based on the author’s experience and observations, this article critically examines the alliance between various stakeholders in Timor-Leste engaging with the fact that the current scene of participatory theater can hardly be seen as an independent grassroots or even social movement, rather than an initiated top-down process by donors with specific agendas.

    INtraoperative Video Enhanced Surgical procedure Training (INVEST) is a new training method designed to improve the transition from basic skills training in a skills lab to procedural training in the operating theater. Traditionally, the master-apprentice model (MAM) is used for procedural training in the operating theater, but this model lacks uniformity and efficiency at the beginning of the learning curve. This study was designed to investigate the effectiveness and efficiency of INVEST compared to MAM. Ten surgical residents with no laparoscopic experience were recruited for a laparoscopic cholecystectomy training curriculum either by the MAM or with INVEST. After a uniform course in basic laparoscopic skills, each trainee performed six cholecystectomies that were digitally recorded. For 14 steps of the procedure, an observer who was blinded for the type of training determined whether the step was performed entirely by the trainee (2 points), partially by the trainee (1 point), or by the supervisor (0 points). Time measurements revealed the total procedure time and the amount of effective procedure time during which the trainee acted as the operating surgeon. Results were compared between both groups. Trainees in the INVEST group were awarded statistically significant more points (115.8 vs. 70.2; p < 0.001) and performed more steps without the interference of the supervisor (46.6 vs. 18.8; p < 0.001). Total procedure time was not lengthened by INVEST, and the part performed by trainees was significantly larger (69.9 vs. 54.1 %; p = 0.004). INVEST enhances effectiveness and training efficiency for procedural training inside the operating theater without compromising operating theater time efficiency.

    Since 2001, U.S. military personnel and active duty, uniformed physicians providing medical support have been deployed to Afghanistan. Medical toxicologists are among the physicians deployed. There is a paucity of information present in the literature that has documented cases treated by toxicologists in theater. This prospective observational study describes 15 male patients treated in theater by a military medical toxicologist. We performed a prospective observational study in which a medical toxicologist consulted and reported on deployed toxicology cases occurring during a 5-month deployment to Bagram, Afghanistan. Fifteen toxicology cases were collected during the 5-month period. The patients included three Afghan civilians, three U.S. civilians, and nine U.S. military personnel. Eight cases were attempts at recreational euphoria, two were self-harm attempts, two were from performance-enhancing supplements, two were accidental occupational exposures and one was alcohol withdrawal. Methanol was the most common exposure followed by dextromethorphan, supplements, opiates, and chlorine gas. In our study, we found that toxic alcohols and nonprescription medications were the most common exposures. In addition, this is the first study to describe bedside toxicology consults for U.S. combat forces in theater and the use of an observation unit for critically ill patients.

    The importance of maintaining performance of a hospital operating theater is to establish an adequate circulation of clean air within the room. The parameter of air distribution in a space should be based on Air Changes per Hour (ACH) to maintain a positive room pressure. The dispersion of airborne particles in the operating theater was governed by regulating the air distribution so that the operating theater meets clean room standards ie ISO 14664 and ASHRAE 170. Here, we introduced several input parameters in a simulation environment to observe the pressure distribution in the room. Input parameters were air temperature, air velocity and volumetric flow rate entering and leaving room for existing and designed condition. In the existing operating theatre, several observations were found. It was found that the outlet air velocity at the HEPA filter above the operating table was too high thus causing a turbulent airflow pattern. Moreover, the setting temperature at 19°C was found to be too low. The supply of air into the room was observed at lower than 20 ACH which is under the standard requirement. Our simulation using FloVent 8.2™ program showed that not only airflow turbulence could be reduced but also the amount of particle contamination could also be minimized.

    2012-03-01

    Along with the success of the digitally revived stereoscopic cinema, events beyond 3D movies become attractive for movie theater operators, i.e. interactive 3D games. In this paper, we present a case that explores possible challenges and solutions for interactive 3D games to be played by a movie theater audience. We analyze the setting and showcase current issues related to lighting and interaction. Our second focus is to provide gameplay mechanics that make special use of stereoscopy, especially depth-based game design. Based on these results, we present YouDash3D, a game prototype that explores public stereoscopic gameplay in a reduced kiosk setup. It features live 3D HD video stream of a professional stereo camera rig rendered in a real-time game scene. We use the effect to place the stereoscopic effigies of players into the digital game. The game showcases how stereoscopic vision can provide for a novel depth-based game mechanic. Projected trigger zones and distributed clusters of the audience video allow for easy adaptation to larger audiences and 3D movie theater gaming.

    Full Text Available Youth is one of the challenging issues to social development policies in Latin America. When socially vulnerable, this age group is at risk of losing future prospects in case minimum conditions are not ensured for active participation in the process of gaining citizenship. In this sense, it is important to develop actions to enable a reduction of the vulnerability process impacts in their daily lives. In this study, we aimed to describe and analyze the use of drama as a therapeutic resource with young people in occupational social vulnerability in the process of awareness and youth participation. To this end, we carried out a case study with qualitative approach in a philanthropic institution in the state of Minas Gerais. Ten meetings were conducted using drama the activities proposed by Augusto Boal, a theatrical presentation to the community using the technique of the theater-forum and focus groups. Data collection occurred through filming and the production of journals analyzed by Content Analysis. We developed three thematic categories: drama as an instrument of expression of the vulnerability conditions of young people; drama and social microcosm of the group and the family; and Theatre Forum and the development of coping strategies. Throughout the process, the technique of the theater of the oppressed enabled the critical thinking development of young people regarding the problems experienced, which helped to promote a dialogue with the community and the family. The community realized the social role of theater, reflecting on the problems experienced by youth.

    The creative process is fun, complex, and sometimes frustrating, but it is critical to the future of our nation and progress in science, technology, engineering, mathematics (STEM), as well as other fields. Thus, we set out to see if implementing methods of active learning typical to the theater department could impact the creativity of senior capstone design students in the bioengineering (BE) department. Senior bioengineering capstone design students were allowed to self-select into groups. Prior to the beginning of coursework, all students completed a validated survey measuring engineering design self-efficacy. The control and experimental groups both received standard instruction, but in addition the experimental group received 1 h per week of creativity training developed by a theater professor. Following the semester, the students again completed the self-efficacy survey. The surveys were examined to identify differences in the initial and final self-efficacy in the experimental and control groups over the course of the semester. An analysis of variance was used to compare the experimental and control groups with p engineering design following the semester of creativity instruction. The results of this pilot study indicate that there is a significant potential to improve engineering students' creative self-efficacy through the implementation of a "curriculum of creativity" which is developed using theater methods.

    This paper presents investigation of Ti-Ni alloy phase formation and its effect on valence band (VB) photoemission and photoresonance study of as-deposited as well as annealed Ti/Ni multilayers (MLs) up to 600 deg. C using synchrotron radiation. For this purpose [Ti (50 A)/Ni (50 A)]X 10 ML structures were deposited by using electron-beam evaporation technique under ultra-high vacuum (UHV) conditions. Formation of different phases of Ti-Ni alloy due to annealing treatment has been confirmed by the X-ray diffraction (XRD) technique. The XRD pattern corresponding as-deposited ML sample shows crystalline nature of both Ti and Ni deposited layers, whereas 300 deg. C annealed ML sample show solid-state reaction (SSR) leading to amorphization and subsequent recrystallisation at higher temperatures of annealing (≥400 deg. C) with the formation of TiNi, TiNi 3 and Ti 2 Ni alloy phases. The survey scans corresponding to 400, 500 and 600 deg. C annealed ML sample shows interdiffusion and intermixing of Ni atoms into Ti layers leading to chemical Ti-Ni alloys phase formation at interface. The corresponding recorded VB spectra using synchrotron radiation at 134 eV on as-deposited ML sample with successive sputtering shows alternately photoemission bands due to Ti 3d and Ni 3d, respectively, indicating there is no mixing of the consequent layers and any phase formation at the interface during deposition. However, ML samples annealed at higher temperatures of annealing, particularly at 400, 500 and 600 deg. C show a clear shift in Ni 3d band and its satellite peak position to higher BE side indicates Ti-Ni alloy phase formation. In addition to this, reduction of satellite peak intensity and Ni 3d density of states (DOS) near Fermi level is also observed due to Ti-Ni phase formation with higher annealing temperatures. The variable photon energy VB measurements on as-deposited and ML samples annealed at 400 deg. C confirms existence and BE position of observed Ni 3d satellite

  2. Evaporation of tiny water aggregation on solid surfaces with different wetting properties.

    The evaporation of a tiny amount of water on the solid surface with different wettabilities has been studied by molecular dynamics simulations. From nonequilibrium MD simulations, we found that, as the surface changed from hydrophobic to hydrophilic, the evaporation speed did not show a monotonic decrease as intuitively expected, but increased first, and then decreased after it reached a maximum value. The analysis of the simulation trajectory and calculation of the surface water interaction illustrate that the competition between the number of water molecules on the water-gas surface from where the water molecules can evaporate and the potential barrier to prevent those water molecules from evaporating results in the unexpected behavior of the evaporation. This finding is helpful in understanding the evaporation on biological surfaces, designing artificial surfaces of ultrafast water evaporating, or preserving water in soil.

Here we report a new arthropod with 10 tiny arthropods tethered to its tergites by long individual threads. The head of the host, which is covered by a shield that projects anteriorly, bears a long stout uniramous antenna and a chelate limb followed by two biramous appendages. The trunk comprises 11 segments, all bearing limbs and covered by tergites with long slender lateral spines. A short telson bears long parallel cerci. Our phylogenetic analysis resolves the new arthropod as a stem-group mandibulate. The evidence suggests that the tethered individuals are juveniles and the association represents a complex brooding behavior. Alternative possibilities—that the tethered individuals represent a different epizoic or parasitic arthropod—appear less likely.

    Nanocrystals, despite their tiny sizes, contain thousands to millions of atoms. Here we show that the large number of atoms packed in each metallic nanocrystal can provide a huge gain in signal amplification for biomolecule detection. We have devised a highly sensitive, linear amplification scheme by integrating the dissolution of bound nanocrystals and metal-induced stoichiometric chromogenesis, and demonstrated that signal amplification is fully defined by the size and atom density of nanocrystals, which can be optimized through well-controlled nanocrystal synthesis. Further, the rich library of chromogenic reactions allows implementation of this scheme in various assay formats, as demonstrated by the iron oxide nanoparticle linked immunosorbent assay (ILISA) and blotting assay developed in this study. Our results indicate that, owing to the inherent simplicity, high sensitivity and repeatability, the nanocrystal based amplification scheme can significantly improve biomolecule quantification in both laboratory research and clinical diagnostics. This novel method adds a new dimension to current nanoparticle-based bioassays. PMID:23659350

    Full Text Available Abstract Background Nyctotherus ovalis is a single-celled eukaryote that has hydrogen-producing mitochondria and lives in the hindgut of cockroaches. Like all members of the ciliate taxon, it has two types of nuclei, a micronucleus and a macronucleus. N. ovalis generates its macronuclear chromosomes by forming polytene chromosomes that subsequently develop into macronuclear chromosomes by DNA elimination and rearrangement. Results We examined the structure of these gene-sized macronuclear chromosomes in N. ovalis. We determined the telomeres, subtelomeric regions, UTRs, coding regions and introns by sequencing a large set of macronuclear DNA sequences (4,242 and cDNAs (5,484 and comparing them with each other. The telomeres consist of repeats CCC(AAAACCCCn, similar to those in spirotrichous ciliates such as Euplotes, Sterkiella (Oxytricha and Stylonychia. Per sequenced chromosome we found evidence for either a single protein-coding gene, a single tRNA, or the complete ribosomal RNAs cluster. Hence the chromosomes appear to encode single transcripts. In the short subtelomeric regions we identified a few overrepresented motifs that could be involved in gene regulation, but there is no consensus polyadenylation site. The introns are short (21–29 nucleotides, and a significant fraction (1/3 of the tiny introns is conserved in the distantly related ciliate Paramecium tetraurelia. As has been observed in P. tetraurelia, the N. ovalis introns tend to contain in-frame stop codons or have a length that is not dividable by three. This pattern causes premature termination of mRNA translation in the event of intron retention, and potentially degradation of unspliced mRNAs by the nonsense-mediated mRNA decay pathway. Conclusion The combination of short leaders, tiny introns and single genes leads to very minimal macronuclear chromosomes. The smallest we identified contained only 150 nucleotides.

    1. In the Neotropics, most plants depend on animals for pollination. Solitary bees are the most important vectors, and among them members of the tribe Centridini depend on oil from flowers (mainly Malpighiaceae) to feed their larvae. This specialized relationship within 'the smallest of all worlds' (a whole pollination network) could result in a 'tiny world' different from the whole system. This 'tiny world' would have higher nestedness, shorter path lengths, lower modularity and higher resilience if compared with the whole pollination network. 2. In the present study, we contrasted a network of oil-flowers and their visitors from a Brazilian steppe ('caatinga') to whole pollination networks from all over the world. 3. A network approach was used to measure network structure and, finally, to test fragility. The oil-flower network studied was more nested (NODF = 0.84, N = 0.96) than all of the whole pollination networks studied. Average path lengths in the two-mode network were shorter (one node, both for bee and plant one-mode network projections) and modularity was lower (M = 0.22 and four modules) than in all of the whole pollination networks. Extinctions had no or small effects on the network structure, with an average change in nestedness smaller than 2% in most of the cases studied; and only two species caused coextinctions. The higher the degree of the removed species, the stronger the effect and the higher the probability of a decrease in nestedness. 4. We conclude that the oil-flower subweb is more cohesive and resilient than whole pollination networks. Therefore, the Malpighiaceae have a robust pollination service in the Neotropics. Our findings reinforce the hypothesis that each ecological service is in fact a mosaic of different subservices with a hierarchical structure ('webs within webs').

  8. TinyONet: A Cache-Based Sensor Network Bridge Enabling Sensing Data Reusability and Customized Wireless Sensor Network Services

    In recent years, a few protocol bridge research projects have been announced to enable a seamless integration of Wireless Sensor Networks (WSNs) with the TCP/IP network. These studies have ensured the transparent end-to-end communication between two network sides in the node-centric manner. Researchers expect this integration will trigger the development of various application domains. However, prior research projects have not fully explored some essential features for WSNs, especially the reusability of sensing data and the data-centric communication. To resolve these issues, we suggested a new protocol bridge system named TinyONet. In TinyONet, virtual sensors play roles as virtual counterparts of physical sensors and they dynamically group to make a functional entity, Slice. Instead of direct interaction with individual physical sensors, each sensor application uses its own WSN service provided by Slices. If a new kind of service is required in TinyONet, the corresponding function can be dynamically added at runtime. Beside the data-centric communication, it also supports the node-centric communication and the synchronous access. In order to show the effectiveness of the system, we implemented TinyONet on an embedded Linux machine and evaluated it with several experimental scenarios. PMID:27873968

    To develop and assess a technique for self-gated fetal cardiac cine magnetic resonance imaging (MRI) using tiny golden angle radial sampling combined with iGRASP (iterative Golden-angle RAdial Sparse Parallel) for accelerated acquisition based on parallel imaging and compressed sensing. Fetal cardiac data were acquired from five volunteers in gestational week 29-37 at 1.5T using tiny golden angles for eddy currents reduction. The acquired multicoil radial projections were input to a principal component analysis-based compression stage. The cardiac self-gating (CSG) signal for cardiac gating was extracted from the acquired radial projections and the iGRASP reconstruction procedure was applied. In all acquisitions, a total of 4000 radial spokes were acquired within a breath-hold of less than 15 seconds using a balanced steady-state free precession pulse sequence. The images were qualitatively compared by two independent observers (on a scale of 1-4) to a single midventricular cine image from metric optimized gating (MOG) and real-time acquisitions. For iGRASP and MOG images, good overall image quality (2.8 ± 0.4 and 2.6 ± 1.3, respectively, for observer 1; 3.6 ± 0.5 and 3.4 ± 0.9, respectively, for observer 2) and cardiac diagnostic quality (3.8 ± 0.4 and 3.4 ± 0.9, respectively, for observer 1; 3.6 ± 0.5 and 3.6 ± 0.9, respectively, for observer 2) were obtained, with visualized myocardial thickening over the cardiac cycle and well-defined myocardial borders to ventricular lumen and liver/lung tissue. For iGRASP, MOG, and real time, left ventricular lumen diameter (14.1 ± 2.2 mm, 14.2 ± 1.9 mm, 14.7 ± 1.1 mm, respectively) and wall thickness (2.7 ± 0.3 mm, 2.6 ± 0.3 mm, 3.0 ± 0.4, respectively) showed agreement and no statistically significant difference was found (all P > 0.05). Images with iGRASP tended to have higher overall image quality scores compared with MOG and particularly

    In recent years there are growing interest in fabrication of bulk nanostructured metals and alloys by using severe plastic deformation (SPD) techniques as new alternative in producing bulk nanocrystalline materials. These techniques allows for processing of bulk, fully dense workpiece with ultrafine grains. Metal undergoes SPD processing in certain techniques such as high pressure torsion (HPT), equal-channel angular pressing (ECAP) or multi-directional forging (MDF) are subjected to extensive hydrostatic pressure that may be used to impart a very high strain to the bulk solid without the introduction of any significant change in overall dimension of the sample. The change in the structure (small grain size and high-volume fraction of grain boundaries) of the material may result in the corrosion behavior different from that of the coarse-grained material. Electrochemical measurements were done to understand the corrosion behavior of TiNi alloys before and after HPT deformation. The experiment was carried out using standard three electrode setup (a sample as working electrode; a platinum wire as a counter electrode and a saturated calomel electrode in saturated KCl as a reference electrode) with the surface area of 26.42 mm2 exposed to the EMEM+10% FBS cell culture medium. The measurements were performed in an incubator with controlled environment at 37 °C and 5% CO2, simulating the cell culture condition. The potential of the specimen was monitored over 1 hour, and the stabilized potential was used as the open-circuit potential (EOCP). Potentiodynamic curves were scanned in the potential range from -0.5 V to 1.5 V relative to the EOCP, at a rate of 0.5 mV/s. The result of OCP-time measurement done in the cell culture medium shows that the OCP of HPT-deformed samples shifts towards to the more positive rather than that of BHPT samples. The OCP of deformed samples were ennobled to more than +70 mV for Ti-50mol%. The shift of OCP towards the nobler direction

  11. A common body of care: the ethics and politics of teamwork in the operating theater are inseparable.

    In the operating theater, the micro-politics of practice, such as interpersonal communications, are central to patient safety and are intimately tied with values as well as knowledge and skills. Team communication is a shared and distributed work activity. In an era of "professionalism," that must now encompass "interprofessionalism," a virtue ethics framework is often invoked to inform practice choices, with reference to phronesis or practical wisdom. However, such a framework is typically cast in individualistic terms as a character trait, rather than in terms of a distributed quality that may be constituted through intentionally collaborative practice, or is an emerging property of a complex, adaptive system. A virtue ethics approach is a necessary but not sufficient condition for a collaborative bioethics within the operating theater. There is also an ecological imperative-the patient's entry into the household (oikos) of the operating theater invokes the need for "hospitality" as a form of ethical practice.

    2003-11-01

    This thesis reports on the study of the acoustic properties of 18 theaters belonging to the Andalusian historical and architectural heritage. These theaters have undergone recent renovations to modernize and equip them appropriately. Coincident with this work, evaluations and qualification assessments with regard to their acoustic properties have been carried out for the individual theaters and for the group as a whole. Data measurements for this purpose consisted of acoustic measurements in situ, both before the renovation and after the renovation. These results have been compared with computer simulations of sound fields. Variables and parameters considered include the following: reverberation time, rapid speech transition index, back-ground noise, definition, clarity, strength, lateral efficiency, interaural cross-correlation coefficient, volume/seat ratio, volume/audience-area ratio. Based on the measurements and analysis, general conclusions are given in regard to the acoustic performance of theaters whose typology and size are comparable to those that were used in this study (between 800 and 8000 cubic meters). It is noted that these properties are comparable to those of the majority of European theaters. The results and conclusions are presented so that they should be of interest to architectural acoustics practitioners and to architects who are involved in the planning of renovation projects for theaters Thesis advisors: Juan J.

    Episodic tremor and slip (ETS) has been observed in many subduction zones, but its mechanical underpinnings as well as its potential for triggering damaging earthquakes have proven difficult to assess. Here we use a seismic array in Cascadia of unprecedented density to monitor seismicity around a moderate 16 day ETS episode. In the 4 months of data we examine, we observe five tiny earthquakes within the subducting slab during the episode and only one more in the same area, which was just before and nearby the next ETS burst. These earthquakes concentrate along the sides and updip edge of the ETS region, consistent with greater stress concentration there than near the middle and downdip edge of the tremor area. Most of the seismicity is below the megathrust, with a similar depth extent to the background intraslab seismicity. The pattern of earthquakes that we find suggests slow slip has a more continuous temporal and spatial pattern than the tremor loci, which notoriously appear in bursts, jumps, and streaks.

  17. Tuning Valley Polarization in a WSe_{2} Monolayer with a Tiny Magnetic Field

    Directory of Open Access Journals (Sweden)

    T. Smoleński

    2016-05-01

    Full Text Available In monolayers of semiconducting transition metal dichalcogenides, the light helicity (σ^{+} or σ^{-} is locked to the valley degree of freedom, leading to the possibility of optical initialization of distinct valley populations. However, an extremely rapid valley pseudospin relaxation (at the time scale of picoseconds occurring for optically bright (electric-dipole active excitons imposes some limitations on the development of opto-valleytronics. Here, we show that valley pseudospin relaxation of excitons can be significantly suppressed in a WSe_{2} monolayer, a direct-gap two-dimensional semiconductor with the exciton ground state being optically dark. We demonstrate that the already inefficient relaxation of the exciton pseudospin in such a system can be suppressed even further by the application of a tiny magnetic field of about 100 mT. Time-resolved spectroscopy reveals the pseudospin dynamics to be a two-step relaxation process. An initial decay of the pseudospin occurs at the level of dark excitons on a time scale of 100 ps, which is tunable with a magnetic field. This decay is followed by even longer decay (>1  ns, once the dark excitons form more complex pseudo-particles allowing for their radiative recombination. Our findings of slow valley pseudospin relaxation easily manipulated by the magnetic field open new prospects for engineering the dynamics of the valley pseudospin in transition metal dichalcogenides.

  18. The splicing of tiny introns of Paramecium is controlled by MAGO.

    The exon junction complex (EJC) is a key element of the splicing machinery. The EJC core is composed of eIF4A3, MAGO, Y14 and MLN51. Few accessory proteins, such as CWC22 or UPF3, bind transiently to the EJC. The EJC has been implicated in the control of the splicing of long introns. To ascertain whether the EJC controls the splicing of short introns, we used Paramecium tetraurelia as a model organism, since it has thousands of very tiny introns. To elucidate whether EJC affects intron splicing in P. tetraurelia, we searched for EJC protein-coding genes, and silenced those genes coding for eIF4A3, MAGO and CWC22. We found that P. tetraurelia likely assembles an active EJC with only three of the core proteins, since MLN51 is lacking. Silencing of eIF4A3 or CWC22 genes, but not that of MAGO, caused lethality. Silencing of the MAGO gene caused either an increase, decrease, or no change in intron retention levels of some intron-containing mRNAs used as reporters. We suggest that a fine-tuning expression of EJC genes is required for steady intron removal in P. tetraurelia. Taking into consideration our results and those published by others, we conclude that the EJC controls splicing independently of the intron size. Copyright © 2018 Elsevier B.V. All rights reserved.

  19. Enhanced water collection through a periodic array of tiny holes in dropwise condensation

    2018-02-01

    This paper introduces a simple method of water collection by increasing the coalescence effects in dropwise condensation with the use of microscale holes. The tiny holes modified the surface free energy states of the droplets on the plate, yielding a surface free energy barrier between the flat solid surface and the holes. The spatial difference in the surface free energy of the droplets enabled the droplets to move toward the adjacent droplets, thus increasing the possibility of coalescence. The water collection experiments were performed using a Peltier-based cooling system at 2 °C inside a chamber at 30 °C and 70% humidity. The results demonstrated that the perforated plates without any additional treatment provided the water collection rate of up to 22.64 L/m2 day, which shows an increase of 30% compared to that demonstrated by the bare plate. By comparing the experimental results for the surface of filmwise condensation, it was proved that the dominant water collecting improvement results from the increased coalescence effects. This simple technique can enhance the performance of systems exposed to water condensation, including water collection, heat-transfer, and dehumidifying systems.

  20. ARECIBO MULTI-EPOCH H I ABSORPTION MEASUREMENTS AGAINST PULSARS: TINY-SCALE ATOMIC STRUCTURE

    We present results from multi-epoch neutral hydrogen (H I) absorption observations of six bright pulsars with the Arecibo telescope. Moving through the interstellar medium (ISM) with transverse velocities of 10-150 AU yr -1 , these pulsars have swept across 1-200 AU over the course of our experiment, allowing us to probe the existence and properties of the tiny-scale atomic structure (TSAS) in the cold neutral medium (CNM). While most of the observed pulsars show no significant change in their H I absorption spectra, we have identified at least two clear TSAS-induced opacity variations in the direction of B1929+10. These observations require strong spatial inhomogeneities in either the TSAS clouds' physical properties themselves or else in the clouds' galactic distribution. While TSAS is occasionally detected on spatial scales down to 10 AU, it is too rare to be characterized by a spectrum of turbulent CNM fluctuations on scales of 10 1 -10 3 AU, as previously suggested by some work. In the direction of B1929+10, an apparent correlation between TSAS and interstellar clouds inside the warm Local Bubble (LB) indicates that TSAS may be tracing the fragmentation of the LB wall via hydrodynamic instabilities. While similar fragmentation events occur frequently throughout the ISM, the warm medium surrounding these cold cloudlets induces a natural selection effect wherein small TSAS clouds evaporate quickly and are rare, while large clouds survive longer and become a general property of the ISM.

    2000-01-01

    Possible orders in URu 2 Si 2 are investigated using a two-channel degenerate Anderson model. The ground state of uranium ions is the non-Kramers quadrupolar doublet Γ 5 with (5f) 2 , and its relevant excited state is the Kramers dipolar doublet Γ 7 with (5f) 1 . These states mix with each other via conduction electrons. At low temperatures, the system forms renormalized bands with both quadrupole and dipole degrees of freedom due to the quadrupolar Kondo effect which slightly mixes quadrupolar Γ 5 , a primary state of uranium ions, with dipolar Γ 7 . At a certain low temperature, conduction electrons in the renormalized bands undergo quadrupolar ordering with a large quadrupolar moment. At a further lower temperature, octupolar ordering occurs, accompanied by a tiny dipolar moment which is attributed to the property of the renormalized bands with primarily the Γ 5 -character slightly mixed with the Γ 7 -character. These phenomena are well described by the 1/N-expansion method with pseudo-fermions for the non-Kramers doublet Γ 5 and slave bosons for the Kramers doublet Γ 7 . (author)

    2014-03-01

    Full Text Available The transformation-induced stress relaxation and stress recovery of TiNi shape memory alloy (SMA in stress-controlled subloop loading were investigated based on the local variation in temperature and transformation band on the surface of the tape in the tension test. The results obtained are summarized as follows. (1 In the loading process, temperature increases due to the exothermic martensitic transformation (MT until the holding strain and thereafter temperature decreases while holding the strain constant, resulting in stress relaxation due to the MT; (2 In the unloading process, temperature decreases due to the endothermic reverse transformation until the holding strain and thereafter temperature increases while holding the strain constant, resulting in stress recovery due to the reverse transformation; (3 Stress varies markedly in the initial stage followed by gradual change while holding the strain constant; (4 If the stress rate is high until the holding strain in the loading and unloading processes, both stress relaxation and stress recovery are large; (5 It is important to take into account this behavior in the design of SMA elements, since the force of SMA elements varies even if the atmospheric temperature is kept constant.

    This paper presents an investigation of thermomechanical effects related to the phenomena of stress relaxation occurring in TiNi SMA subjected to modified program of displacement-controlled tension. The deformation data were taken from testing machine, whereas the temperature changes accompanying the exothermic/endothermic martensite forward/reverse transformation were measured by infrared camera. At the advanced stages of the transformations, the strain was kept constant for a few minutes and the SMA load and temperature were recorded continuously. As a consequence, the stress and temperature changed significantly during the loading stops. A large stress drop, caused by the transformation, was observed during the relaxation stage in both courses of the SMA loading and unloading. Moreover, the non-uniform temperature distribution, reflecting macroscopically inhomogeneous transformation, lapsed while the strain was kept constant, yet restarted at the end of the relaxation stop and developed at the reloading stage. Along with the experimental results, the mechanical and thermal responses induced by the transformation were obtained by 3D coupled thermomechanical numerical analysis, realized in partitioned approach. Latent heat production was correlated with an amount of the martensitic volume fraction. The stress and temperature drops recorded during the experiment were satisfactorily reproduced by the model proposed for the SMA thermomechanical coupling.

    Full Text Available Wireless sensor network (WSN has been already widely used in many fields in terms of industry, agriculture, and military, and so forth. The basic composition is WSN nodes that are capable of performing processing, gathering information, and communicating with other connected nodes in the network. The main components of a WSN node are microcontroller, transceiver, and some sensors. Undoubtedly, it also can be added with some actuators to form a tiny mechanical system. Under this case, the existence of task preemption while executing operating system will not only cost more energy for WSN nodes themselves, but also bring unacceptable system states caused by vibrations. However for these nodes, task I/O delays are inevitable due to the existence of task preemption, which will bring extra overhead for the whole system, and even bring unacceptable system states caused by vibrations. This paper mainly considers the earliest deadline first (EDF task preemption algorithm executed in WSN OS and proposes an improved task preemption algorithm so as to lower the preemption overhead and I/O delay and then improve the system performance. The experimental results show that the improved task preemption algorithm can reduce the I/O delay effectively, so the real-time processing ability of the system is enhanced.

    Full Text Available We describe an articulated partial leg of an Oligocene bird. It is one of the smallest avian fossils ever recorded. Its slender and exceptionally short tarsometatarsus, hallux as long as the tarsometatarsus and stout moderately curved claws agree with stem-group Apodidae (swifts, stem-group Trochilidae (hummingbirds, and stem-group Upupidae/Phoeniculidae (hoopoes/woodhoopoes. Unfortunately, due to the poor preservation of the specimen its more precise affinities remain unresolved. The specimen differs in many details from all other tiny Palaeogene birds and therefore most probably it represents a new taxon but it is too fragmentary to describe it. It is just the twelfth avian fossil from the Oligocene marine deposits of the Outer Carpathians and Central Palaeogene Basin — a huge area that covers south-eastern Poland, north-eastern Czech Republic and northern Slovakia — and therefore it adds to our very limited knowledge on the avifauna of that region. The remains of land birds from Jamna Dolna and other sites of the region can be attributed to the general sea level fall at that time, which led to limitation of the connection with the open ocean and resulted in many shallow shoals, temporary islands and exposed dry land areas along the coast.

    We use Monte Carlo simulations to carry out a thorough analysis of structural correlations arising in a relatively dense fluid of rigid spherical particles with prototype competing interactions (short-range attractive and long-range repulsive two-Yukawa model). As the attraction strength increases, we show that the local density of the fluid displays a tiny reversal of trend within specific ranges of interparticle distances, whereupon it decreases first and increases afterwards, passing through a local minimum. Particles involved in this trend display, accordingly, distinct behaviours: for a sufficiently weak attraction, they seem to contribute to the long-wave oscillations typically heralding the formation of patterns in such fluids; for a stronger attraction, after the reversal of the local density has occurred, they form an outer shell of neighbours stabilizing the existing aggregation seeds. Following the increment of attraction, precisely in correspondence of the local density reversal, the local peak developed in the structure factor at small wavevectors markedly rises, signalling-in agreement with recent structural criteria-the onset of a clustered state. A detailed cluster analysis of microscopic configurations fully validates this picture.

Relying on primary source documents from the war, this article provides the first discussion of the management of vascular injuries in the island-hopping battles of the Pacific. It explains how the particular military, logistic, and geographic conditions of this theater influenced medical and surgical care, prompting a continued emphasis on ligation when surgeons in Europe had already transitioned to repairing arteries.

    This report describes the methodology and results of independent verification and validation performed on a combat model in its design stage. The combat model is the Future Theater Level Model (FTLM), under development by The Joint Staff/J-8. J-8 has undertaken its development to provide an analysis tool that addresses the uncertainties of combat more directly than previous models and yields more rapid study results. The methodology adopted for this verification and validation consisted of document analyses. Included were detailed examination of the FTLM design documents (at all stages of development), the FTLM Mission Needs Statement, and selected documentation for other theater level combat models. These documents were compared to assess the FTLM as to its design stage, its purpose as an analytical combat model, and its capabilities as specified in the Mission Needs Statement. The conceptual design passed those tests. The recommendations included specific modifications as well as a recommendation for continued development. The methodology is significant because independent verification and validation have not been previously reported as being performed on a combat model in its design stage. The results are significant because The Joint Staff/J-8 will be using the recommendations from this study in determining whether to proceed with develop of the model.

  11. Electron irradiation effect on the reverse phase transformation temperatures in TiNi shape memory alloy thin films

    In this work, Ti-Ni shape memory alloy thin films were irradiated by 1.7 MeV electron with three types of fluences: 4 x 10 20 , 7 x 10 20 and 1 x 10 21 /m 2 . The influence of electron irradiation on the transformation behavior of the TiNi thin films were investigated by differential scanning calorimetry. The transformation temperatures A s and A f shifted to higher temperature after electron irradiation, the martensite was stabilized. The electron irradiation effect can be easily eliminated by one thermal cycle. The shifts of the transformation temperatures can be explained from the change of potential energy barrier and coherency energy between parent phase and martensite after irradiation

    The corrosive erosion behavior of Ti-51at.%Ni alloy under different erosion conditions was studied and compared to that of 304 stainless steel. Erosion tests were performed in a slurry-pot tester with dry sand, 3.5% NaCl slurry and 0.1 moll{sup -1} H{sub 2}SO{sub 4} slurry containing 30% silica sand, respectively. Synergistic effects of corrosion and erosion were studied in steady corrosion, polarization, dry sand erosion and micro-wear experiments. An electrochemical-scratching test characterized the failure and recovery of the passive film formed on TiNi alloy in 3.5% NaCl and 0.1 mol l{sup -1} H{sub 2}SO{sub 4} solutions, respectively. In both dry sand and the corrosive media, the TiNi alloy exhibited considerably greater erosion resistance than 304 stainless steel. (orig.)

  13. Effects of post-irradiation annealing on the transformation behavior of Ti-Ni alloys

    Recovery processes of martensitic transformation of neutron irradiated Ti-50.0, 50.5 and 51.0 at.%Ni alloys during post-irradiation annealing were investigated by means of differential scanning calorimetry (DSC), tensile tests and transmission electron microscope (TEM) observations. Neutron irradiation up to a fluence of 1.2x10 24 n/cm 2 at 333 K suppressed the martensitic transformation as well as the stress-induced martensitic transformation of these alloys above 150 K. The TEM observations revealed that the disordered zones containing small defect clusters in high density were formed in the neutron irradiated Ti-Ni alloys. The DSC measurements also showed that the post-irradiation annealing caused recovery of the transformation of which the progress depended on the annealing temperature and period. A significant retardation of the recovery was recognized in the Ti-51.0 at.%Ni alloy in comparison with the Ti-50.0 at.%Ni alloy. From the shifts in the transformation temperature upon isothermal annealing at various annealing temperatures, the activation energies of the recovery process of the transformation in the neutron irradiated Ti-50.0 and 51.0 at.%Ni alloys were evaluated by a cross-cut method to be 1.2 eV and 1.5 eV, respectively. The recovery of the transformation was ascribed to the re-ordering resulting from decomposition of vacancy clusters, and those obtained values of the activation energy were considered to be the sum of the migration energy of vacancy and the binding energy of vacancy-vacancy cluster. The retardation of the recovery in the Ti-51.0 at%Ni alloy was interpreted in terms of large binding energy in this alloy due to the off-stoichiometry. (author)

    The first comprehensive geological map, a summary of lithologies and new radiogenic isotope data (U-Pb, Rb-Sr) are presented for crystalline rocks of the Sub-Antarctic Snares Islands/Tini Heke, 150 km south of Stewart Island. The main lithology is Snares Granite (c. 109 Ma from U-Pb dating of zircon), which intrudes Broughton Granodiorite (c. 114 Ma from U-Pb zircon) on Broughton Island. Rafts of schist within Snares Granite are common on the outlying Western Chain islets, and rare on North East and Broughton islands. Zircon grains extracted from one schistose raft on Broughton Island are prismatic and yield an essentially unimodal age population of c. 116 Ma that is within error of the granodiorite. These properties suggest that the dated raft represents a meta-igneous rock despite its mica-rich nature. Some schistose rocks on the Western Chain contain coarse relict plagioclase phenocrysts and appear to have an igneous protolith. No conclusive metasedimentary rocks have been identified, although sillimanite-bearing mica-rich schist occurs on Rua. Deformation of the crystalline rocks occurred after Snares Granite intrusion and before cooling below muscovite K-Ar closure at 400 ± 50 degrees C at 95 Ma. This period overlaps the age of extensional ductile shear zones on Stewart Island. The discovery of several basaltic dykes, which cut across fabrics and are unmetamorphosed, indicates that volcanic rocks are associated with all Sub-Antarctic island groups. The larger of the islands are overlain by peat, which on North East Island also contains gravel deposits. (author).

    Full Text Available To prevent surgical site infection (SSI, the airborne microbial concentration in operating theaters must be reduced. The air quality in operating theaters and nearby areas is also important to healthcare workers. Therefore, this study assessed air quality in the post-operative recovery room, locations surrounding the operating theater area, and operating theaters in a medical center. Temperature, relative humidity (RH, and carbon dioxide (CO2, suspended particulate matter (PM, and bacterial concentrations were monitored weekly over one year. Measurement results reveal clear differences in air quality in different operating theater areas. The post-operative recovery room had significantly higher CO2 and bacterial concentrations than other locations. Bacillus spp., Micrococcus spp., and Staphylococcus spp. bacteria often existed in the operating theater area. Furthermore, Acinetobacter spp. was the main pathogen in the post-operative recovery room (18% and traumatic surgery room (8%. The mixed effect models reveal a strong correlation between number of people in a space and high CO2 concentration after adjusting for sampling locations. In conclusion, air quality in the post-operative recovery room and operating theaters warrants attention, and merits long-term surveillance to protect both surgical patients and healthcare workers.

    Full Text Available Theaterplakate gehören zur Tätigkeit des Theaters. Anfangs erfüllten sie eine reine Gebrauchsfunktion, indem sie über ein kulturelles Ereignis informierten, das an einem bestimmten Tag, zu einer bestimmten Uhrzeit, an einem bestimmten Ort stattfinden wird. Mit der Zeit bekamen sie jedoch die Eigenschaften eines Zeugens aus der Vergangenheit, indem sie die Geschichte ihres Urhebers zeigten, das Profil seiner Tätigkeit, die in seiner Struktur vor sich gehenden Veränderungen. Die Wurzeln der Theaterplakate sind schon in der Antike zu suchen, sie wurden von Ägyptern, Römern und Griechen geschaffen. Das älteste neuzeitliche Plakat erschien 1429 in London und ist heute ein Exponat im Londoner Theatermuseum. Die Geschichte der polnischen Plakate reicht bis ins 16. oder 17. Jahrhundert zurück, hier sind sich die Forscher nicht einig, und ist entweder mit einem Jesuitenkollegium oder mit dem königlichen Theater verbunden. Die im Text analysierten Thorner Plakate stammen aus den Jahren 1922-1975 und werden in den Sammlungen der Kopernikus-Bücherei und in den Beständen des Staatsarchivs in Thorn aufbewahrt. Geschaffen wurden sie vom Theater in Thorn. Heute ist es das Wilam-Horzyca-Theater, doch sein Name, sein Tätigkeitsfeld, seine Organisationsstruktur und auch sein Profil und die Art seiner Tätigkeit änderten sich im Laufe der besprochenen Jahre vielmals. Die Plakate wurden in chronologischer Ordnung mit einer Aufteilung in Gruppen besprochen. Die Autorinnen beachteten den Inhalt, seine Anordnung und die Form der Aufzeichnung, das Format der Plakate, ihre Farbgebung, Ornamentik und die verwendete Ikonographie. Jede Gruppe wurde detailliert besprochen und illustriert. Nicht allein das Theater in Thorn schuf in der Stadt Theaterplakate. Eine ähnliche aktenkundliche Analyse lässt sich in Bezug auf das Puppentheater „Baj Pomorski” durchführen, doch ist das schon Material für einen gesonderten Artikel.

  5. Is Pluto a planet? Student powered video rap ';battle' over tiny Pluto's embattled planetary standing

    Is Pluto a planet? Some creative low income Bay-area middle-schoolers put a musical spin on this hot science debate with a video rap ';battle' over tiny Pluto's embattled planetary standing. The students' timing was perfect, with NASA's New Horizons mission set to conduct the first reconnaissance of Pluto and its moons in July 2015. Pluto - the last of the nine original planets to be explored by spacecraft - has been the subject of scientific study and speculation since Clyde Tombaugh discovered it in 1930, orbiting the Sun far beyond Neptune. Produced by the students and a very creative educator, the video features students 'battling' back and forth over the idea of Pluto being a planet. The group collaborated with actual space scientists to gather information and shot their video before a 'green screen' that was eventually filled with animations and visuals supplied by the New Horizons mission team. The video debuted at the Pluto Science Conference in Maryland in July 2013 - to a rousing response from researchers in attendance. The video marks a nontraditional approach to the ongoing 'great planet debate' while educating viewers on a recently discovered region of the solar system. By the 1990s, researchers had learned that Pluto possessed multiple exotic ices on its surface, a complex atmosphere and seasonal cycles, and a large moon (Charon) that likely resulted from a giant impact on Pluto itself. It also became clear that Pluto was no misfit among the planets - as had long been thought - but the largest and brightest body in a newly discovered 'third zone' of our planetary system called the Kuiper Belt. More recent observations have revealed that Pluto has a rich system of satellites - five known moons - and a surface that changes over time. Scientists even speculate that Pluto may possess an internal ocean. For these and other reasons, the 2003 Planetary Decadal Survey ranked a Pluto/Kuiper Belt mission as the highest priority mission for NASA's newly created

    In the twentieth century, race-based residential and commercial segregation that supported racial oppression and inequality became an elemental characteristic of urban black communities. Conflict-ridden, black-white relationships were common. However, the Chicago Defender Charities, Inc., the entity that sponsors the largest African American parade in the country and that emerged in 1947, embodied a tradition of charitable giving, self-help, and community service initiated in 1921 by Chicago Defender newspaper founder and editor, Robert S. Abbott. The foundation of this charitable tradition matured as a result of an early and sustained collaboration between Chicago’s white-owned Regal Theater and the black-owned Chicago Defender newspaper. Thus, in segregated African American communities, black and white commercial institutions, under certain conditions, were able to find important points of collaboration to uplift the African American communities of which they were a part.

    Full Text Available Training medical students to understand the effects of culture and marginalization on health outcomes is important to the future health of increasingly diverse populations. We devised and evaluated a short training module on working with diversity to challenge students’ thinking about the role of both patient and practitioner culture in health outcomes. The workshop combined didactic teaching about culture as a social determinant of health using the cultural humility model, interactive exercises, and applied theater techniques. We evaluated changes in the students’ perceptions and attitudes over time using the Reaction to Diversity Inventory. There was initial significant improvement. Women and students with no past diversity training responded best. However, scores largely reverted to baseline over 12 months.

    This case report describes the first case in intraoperative magnetic resonance imaging operating theater (iMRI OT) (BrainSuite®) of awake craniotomy for frontal lobe glioma excision in a 24-year-old man undergoing eloquent cortex language mapping intraoperatively. As he was very motivated to take pictures of him while being operated upon, the authors adapted conscious sedation technique with variable depth according to Ramsey's scale, in order to revert to awake state to perform the intended neurosurgical procedure. The patient tolerated the situation satisfactorily and was cooperative till the finish, without any event. We elicit in this report the special environment of iMRI OT for lengthy operation in pinned fixed patient having craniotomy. PMID:25885085

    Stigma impacts >50% of persons with epilepsy (PWE) and is a key factory in quality of life. Stigma can be both enacted (external factors) and felt (internal factors). In this article, felt/perceived stigma is more broadly defined as a combination of internal factors and perceptions of external factors. Secondary perceived stigma is felt/perceived stigma by a third party. A key, but often underappreciated, consideration in felt/perceived stigma may occur when a seemingly innocuous statement by a speaker is perceived as stigmatizing by the PWE and/or even by an unintended third party. This autobiographic short report addresses secondary perceived stigma in a social setting, the theater. Copyright © 2016 Elsevier Inc. All rights reserved.

    2012-05-01

    Just as data from civilian trauma registries have been used to benchmark and evaluate civilian trauma care, data contained within the Joint Theater Trauma Registry (JTTR) present a unique opportunity to benchmark combat care. Using the iterative steps of the benchmarking process, we evaluated data in the JTTR for suitability and established benchmarks for 24-hour mortality in casualties with polytrauma and a moderate or severe blunt traumatic brain injury (TBI). Mortality at 24 hours was greatest in those with polytrauma and a severe blunt TBI. No mortality was seen in casualties with polytrauma and a moderate blunt TBI. Secondary insults after TBI, especially hypothermia and hypoxemia, increased the odds of 24-hour mortality. Data contained in the JTTR were found to be suitable for establishing benchmarks. JTTR data may be useful in establishing benchmarks for other outcomes and types of combat injuries.

    2018-02-23

    Currently, networking has not progressed in the treatment room. Almost every medical device in the treatment room operates as a stand-alone device. In this project, we aim to develop a networked operating room called "Smart Cyber Operating Theater (SCOT)". Medical devices are connected using Open Resource interface for the Network (ORiN) technology. In this paper, we describe the concept of the SCOT project. SCOT is integrated using the communication interface ORiN, which was originally developed for industry. One feature of ORiN is that the system can be constructed flexibly. ORiN creates abstracts of the same type of devices and increases the robustness of the system for device exchange. By using ORiN technology, we are developing new applications, such as decision-making navigation or a precision guided treatment system.

  15. The Cultural Value of Older People's Experiences of Theater-making: A Review.

    2017-04-01

    Although a number of existing reviews document the health and social benefits of arts participation by older people, there are none which focus specifically on theater and drama. This article presents the findings of a study conducted as part of the UK's Arts and Humanities Research Council "Cultural Value Project." The 2-year (2013-2015) "Cultural Value Project" sought to make a major contribution to how we think about the value of arts and culture to individuals and to society. It made 72 awards: 19 critical reviews of existing bodies of research, 46 research development awards to carry out new research, and 7 expert workshop awards to facilitate discussions among academics and practitioners. Together, these awards explored the components of cultural value and the ways in which cultural value is evidenced and evaluated. Following an extensive search of academic databases and E-mail requests via relevant organizations and networks, 77 publications formed the basis for our own critical review. Our findings highlight the benefits and value of older people's theater and drama participation on health and well-being, group relationships, learning and creativity, and draw attention to the importance of the esthetic value and quality of older people's drama. Despite the recent surge of interest in this field (a third of the reviewed literature was published between 2010 and 2014), we suggest that there are multiple areas for further research. © The Author 2016.

  16. What physiological changes and cerebral traces tell us about adhesion to fiction during theater-watching?

    Directory of Open Access Journals (Sweden)

    Marie-Noëlle Metz-Lutz

    2010-08-01

    Full Text Available Live theater is typically designed to alter the state of mind of the audience. Indeed, the perceptual inputs issuing from a live theatrical performance are intended to represent something else, and the actions, emphasised by the writing and staging, are the key prompting the adhesion of viewers to fiction, i.e. their belief that it is real. This phenomenon raises the issue of the cognitive processes governing access to a fictional reality during live theater and of their cerebral underpinnings. To get insight into the physiological substrates of adhesion we recreated the peculiar context of watching live drama in a functional magnetic resonance imaging experiment, with simultaneous recording of heart activity. The instants of adhesion were defined as the co-occurrence of theatrical events determined a priori by the stage director and the spectators’ offline reports of moments when fiction acted as reality. These data served to specify, for each spectator, individual fMRI time-series, used in a random-effect group analysis to define the pattern of brain response to theatrical events. The changes in this pattern related to subjects’ adhesion to fiction, were investigated using a region of interest analysis. The results showed that adhesion to theatrical events correlated with increased activity in the left BA47 and pSTS, together with a decrease in dynamic heart rate variability, leading us to discuss the hypothesis of subtle changes in the subjects’ state of awareness, enabling them to mentally dissociate physical and mental (drama-viewing experiences, to account for the phenomenon of adhesion to dramatic fiction.

These data served to specify, for each spectator, individual fMRI time-series, used in a random-effect group analysis to define the pattern of brain response to theatrical events. The changes in this pattern related to subjects' adhesion to fiction, were investigated using a region of interest analysis. The results showed that adhesion to theatrical events correlated with increased activity in the left BA47 and posterior superior temporal sulcus, together with a decrease in dynamic heart rate variability, leading us to discuss the hypothesis of subtle changes in the subjects' state of awareness, enabling them to mentally dissociate physical and mental (drama-viewing) experiences, to account for the phenomenon of adhesion to dramatic fiction.

    Musical theater performers are the "triathletes" in the performing arts. The field requires versatility in a combination of skills including dancing, singing, and drama in a high frequency of performances. The aim of this study was to analyze and evaluate the health situation of musical theater students using a complete musical educational institute as an example (n = 37). The basis for the evaluation was a questionnaire survey (standardized F 1000). All students of the school participated (20 males, 17 females). Of the students, 62% have a part-time job for financial reasons, and 67.7% state only a "partial satisfaction" with their body. Regarding injury, 45.9% claim to sustain an orthopaedic injury up to twice a year, and 29.7% up to three or four times. A total of 49 acute injuries (1.3/student) and 42 chronic complaints (1.1/student) were stated. The lower extremity was the most common acutely injured region (65.3%), followed by the spine (16.3%) and upper extremity (14.3%). Of chronic complaints, the lumbar spine was the most commonly affected area, followed by the hip joint and pelvic area. Thirty-three and 24% of acute injuries occurred during "spins" and/or "stretching," respectively. There were various causes for physical and mental problems. The results show both parallels and differences to the relevant literature. It is shown that health hazards already arise in the education of musical performers. This provides particulars for the implementation of injury prevention measures during the theoretical and practical education of musical students.

    In addition to self-governing properties, tiny-sized particles of metallic colloids are the building blocks of large-sized particles; thus, their study has been the subject of a large number of publications. In the present work, it has been discussed that geometry structure of tiny particle made through atom-to-atom amalgamation depends on attained dynamics of gold atoms along with protruded orientations. The localized process conditions direct two-dimensional structure of a tiny particle at atomically flat air-solution interface while heating locally dynamically approached atoms, thus, negate the role of van der Waals interactions. At electronphoton-solution interface, impinging electrons stretch or deform atoms of tiny particles depending on the mechanism of impingement. In addition, to strike regular grid of electrons ejected on split of atoms not executing excitations and de-excitations of their electrons, atoms of tiny particles also deform or stretch while occupying various sites depending on the process of synergy. Under suitable impinging electron streams, those tiny particles in monolayer two-dimensional structure electron states of their atoms are diffused in the direction of transferred energy, thus, coincide to the next adjacent atoms in each one-dimensional array dealing the same sort of behavior. Instantaneously, photons of adequate energy propagate on the surfaces of such electronic structures and modify those into smooth elements, thus, disregard the phenomenon of localized surface plasmons. This study highlights the fundamental process of formation of tiny particles where the role of localized dynamics of atoms and their electronic structure along with interaction to light are discussed. Such a tool of processing materials, in nonequilibrium pulse-based process, opens a number of possibilities to develop engineered materials with specific chemical, optical, and electronic properties.

    A method for evaluating electron density using a single fixed-bias Langmuir probe is presented. The technique allows for high-spatio-temporal resolution electron density measurements, which can be effectively carried out by tiny spacecraft for multi-point observations in the ionosphere. The results are compared with the multi-needle Langmuir probe system, which is a scientific instrument developed at the University of Oslo comprising four fixed-bias cylindrical probes that allow small-scale plasma density structures to be characterized in the ionosphere. The technique proposed in this paper can comply with the requirements of future small-sized spacecraft, where the cost-effectiveness, limited space available on the craft, low power consumption and capacity for data-links need to be addressed. The first experimental results in both the plasma laboratory and space confirm the efficiency of the new approach. Moreover, detailed analyses on two challenging issues when deploying the DC Langmuir probe on a tiny spacecraft, which are the limited conductive area of the spacecraft and probe surface contamination, are presented in the paper. It is demonstrated that the limited conductive area, depending on applications, can either be of no concern for the experiment or can be resolved by mitigation methods. Surface contamination has a small impact on the performance of the developed probe.

  1. Effect of hydrogen on transformation characteristics and deformation behavior in a Ti-Ni shape memory alloy

    Transformation characteristics and deformation behavior of hydrogenated Ti-50.5 at% Ni alloys, which were occluded in a low pressure range of hydrogen between 1.1 and 78.5 kPa, have been studied by electrical resistivity measurement, tensile test, X-ray diffraction analysis and microstructural observation. M S temperature of the Ti-Ni alloys decreased with an increase in hydrogen content. This corresponds to the stabilization of the parent phase during cooling, which was confirmed by X-ray diffraction: The suppression effect of hydrogen takes place on the martensitic transformation. Critical stress for slip deformation of hydrogenated Ti-Ni alloys changed with hydrogen content and thus hydrogen had a major influence on deformation behavior of those alloys. With hydrogen contents above 0.032 mol%, hardening was distinguished from softening which was pronounced in the contents from 0 to 0.032 mol% H. Hydrides were formed in hydrogen contents over 1.9 mol%. The hydride formation results in the reorientation in variants of the R phase and increase in the lattice strains of the parent phase.

    Full Text Available In this work, a creative way to teach Physics to the students in Regular Education is suggested, by presenting the following aspects: how it happened, outcomes, and the way to present it to the readers. The theater was chosen, considering that scientific knowledge can be represented beyond its rigidity, at the same time that art provokes reflections in the actor and in the spectator. A group of scientific theater was created in a school in Brejo Santo, Ceará, and besides staging, a website was elaborated. The characters "Traditional Teaching" and "New Physics" are the protagonists of the story and they will show us in their dialogues, how difficult it is, however possible, to show possibilities of Physics teaching through an entertaining approach in regular schools. Among the results, positive changes were noticed in the group, as the student's posture in classroom, besides receptivity and respect among the friends and with the teacher. Besides, they began to see Physics in another way, becoming more motivated to learn this science. In that sense, considering the current brazilian education, the objective of this work focuses on the teacher's need to act in a differentiated way, through strategies and new methodologies. Therefore, the theatrical practice, more specifically, the scientific theater, can be a tool of great didactic potential in teachers’ practice, contributing for teaching process and learning of Physics.

    Although the ventilation system is widely employed in the operating theater, a strictly sterile surgical environment still cannot be ensured because of laminar disturbance, which is mainly caused by the surgical lighting system. Abandoning traditional products, we propose an LED surgical lighting system, which can alleviate the laminar disturbance and provide an appropriate lighting condition for surgery. It contains a certain amount of LED lens units, which are embedded in the ceiling and arranged around the air supply smallpox. The LED lens unit integrated with an LED light source and a free-form lens is required to produce a uniform circular illumination with a large tolerance to the change of lighting distance. To achieve such a dedicated lens, two free-form refractive surfaces, which are converted into two ordinary differential equations by the design method presented in this paper, are used to deflect the rays. The results show that the LED surgical lighting system can provide an excellent illumination environment for surgery, and, apparently, the laminar disturbance also can be relieved.

    In many parts of the world, young adult women have higher levels of common mental disorders than men. The exacerbation of domestic violence (DV) by migration is a salient social determinant of poor mental health. Ecological models describe factors contributing to DV as operating at individual, family, cultural, and societal levels. We explored the interplay among these factors in an Indian community living in Melbourne, Australia, in a qualitative participatory action research study using a modified Forum Theater approach. We here present findings on connections between migration, societal factors, and social/family/cultural factors in DV. The study captured the voices of women living in the community as they describe how DV contributes to their emotional difficulties. Improved understanding of the sociocultural dynamics of DV and the associated social distress in this migrant Indian community can be used to guide the development of culturally sensitive prevention and response programs to assist migrant women from the Indian subcontinent who present with psychopathology and suicidal behaviors associated with DV. © The Author(s) 2015.

    Full Text Available The Opera of the National Theater in Belgrade was founded in 1920, but it is well known that opera performances were held long before its official opening. Despite the fact that this is the sole opera house in Belgrade (and one of the only two in Serbia, as well as the fact that it did not face any strong audience fluctuation, it is unusual that no one ever tried to investigate and profile its audience. During the last decades we were witnessing the popularization of the opera via various medias, as well as development and extention of the music industry, which surely changed its social status. The aim of the investigation that is going to be presented is to discover if this social life of opera changed its audience and does it still consists of - according to stereotypes - elderly, high educated individuals of certain professions and high material standards, i.e. at which level the opera is present in the private and public sphere of their lives.

    Full Text Available Discourse is made of several voices, a premise that was announced since Bakhtin’s studies. The advances in the field of intertextuality allowed a wider specification of the term and broaden the discussion of many different occurrence of the intertext in literature. The work of a German contemporary playwright, Dea Loher, brings the recurrence of intertext, and the present paper aims to investigate this manifestation in two of her plays, Olgas Raum and Licht. Loher uses citation, references and allusions, cutting pieces of other texts and pasting them into her writing. This game of cutting and pasting is also visible inside her aesthetic, as she uses elements that are part of other theatrical aesthetics and adapts them in her work, creating an original style. Representing the political side of theater, Loher provides her reader with the possibility of reflecting and, in the considered two plays, she does it through the deconstruction of the canonic discourse, showing how discourses are made and how they are connected to power maintenance. This way, intertext, the hybrid aesthetic and other aesthetical and linguistic resources are organized to receive these political themes that come to the reader as questions and inquires.

    2017-08-01

    Full Text Available Organizational memory studies (OMS frame memory in a managerial mode, treating it as a data storage, limiting the scope from wider field of social memory studies. There is a lack of understanding about how the process of institutional forgetting works and how some memories stay a part of oral narratives and communicative social memory while they are omitted from the official memory represented by the official documents and events of remembering. Inspired by Paul Connerton’s article on the typology of forgetting we explore his typology in selected case studies of three public theaters located in Belgrade, focusing on remembering policy and practices investigating if a type of forgetting typical for a state/society/nation level is possible to be applied in the context of a cultural organization. We agree with Wessel and Moulds that developing common language and terminology would be important and beneficial for cross disciplinary dialogue. In this sense, the study shows how the typology of forgetting in societies can be applied and developed in the organizational memory studies and cultural management. The focus of the research is the dynamics of remembering and forgetting explored through analysis of the interaction between changing context, official institutional memories, and social communicative memories.

    The knowledge-based methodologies for assessing the structural safety and vulnerability of historical buildings are based on the application of an operational approach that is divided into several phases including historical research, the execution of non-destructive or moderately destructive investigations, monitoring and structural analysis. Monitoring is a useful tool to be used throughout the whole process of knowledge not only in the preliminary diagnosis, but also for the control of the quality and effectiveness of the interventions, in the context of appropriate conservation programs e protection of the object being studied. From this point of view, monitoring becomes essential for: (i) the evaluation of the real structural behavior and the identification of vulnerabilities, prior to the execution of any intervention; (ii) minimization and optimization of interventions, firstly by providing indications regarding those that are not necessary and / or invasive. This methodology has been recently applied and valid from the authors to an archaeological site of particular relevance: the Roman Theater of Verona. The deepening of the knowledge phase (historical analysis, survey, study of the subsoil, properties of materials), combined with the installation of a permanent monitoring system and the structural modeling, allowed to obtain a reliable assessment of the site's vulnerabilities with the aim of guaranteeing in an effective and careful protection and enhancement.

  11. Tourniquets and exsanguinators: a potential source of infection in the orthopedic operating theater?

    LENUS (Irish Health Repository)

    Brennan, Stephen A

    2009-04-01

    BACKGROUND AND PURPOSE: Fomites are increasingly being recognised as a source of hospital-acquired infection. We have therefore assessed tourniquets and exsanguinators for the presence of bacterial pathogens in 1 elective and 2 trauma orthopedic hospitals. MATERIAL AND METHODS: Swabs were taken prior to and after decontaminating these devices with 1 of 3 different cleaning modalities. These were then assessed for colony counts and organisms identified. RESULTS: Bacteria commonly implicated in surgical site infections such as coagulase-negative staphylococci, Staphylococcus aureus and Proteus spp. were prevalent. We also found a resistant strain of Acinetobacter and Candida. Exsanguinators were the most heavily contaminated devices, and colony counts in the trauma hospitals were up to 400% higher than in the elective hospital. Alcohol- and non-alcohol-based sterile wipes were both highly effective in decontaminating the devices. INTERPRETATION: Infectious organisms reside on the tourniquets and exsanguinators presently used in the orthopedic theater. These fomites may possibly be a source of surgical site infection. We have demonstrated a simple and effective means of decontaminating these devices between cases.

    Full Text Available Objective: To understand the importance of theater as an occupational therapy resource for the prevention of substance abuse by teens enrolled in a community-based psychosocial project. Methods: A qualitative, descriptive study with a critical reflection approach held at a community center in the Community of Dendê, Fortaleza-Ceará, Data were collected from March to May 2009 in a group of ten (10 teenagers of both sexes, aged 12 to 18 years, who lived in socially vulnerable situations and participated in the GESTTO group (Group of Socio-theatrical Expressions in Occupational Therapy. A structured interview was used with a simple observation of groups of theatrical activities and a field book. The analysis of the empirical material was based on Orlandi’s discourse analysis. Results: It was found that theatrical activities used as an occupational therapy resource constitute a powerful tool for the prevention of substance abuse, promoting increased self-esteem, the restructuring of the model of social identity, and the discovery of potentialities and abilities by teenagers so that they can become peer educators for the prevention of substance abuse in the community. Conclusion: The theatrical activity provided teenagers with a clear understanding of the use and abuse of illicit drugs, making them more sensitive to prevention and self-identity, making a significant change in their lives. doi:10.5020/18061230.2013.p333

The scanning part is a tiny piezoelectric tube scanner (industry type: PZT-8, whose d 31 coefficient is one of the lowest) housed in a slightly bigger polished sapphire tube, which is riding on and spring clamped against the knife edges of a tungsten slot. The STM so constructed shows low back-lashing and drifting and high repeatability and immunity to external vibrations. These are confirmed by its low imaging voltages, low distortions in the spiral scanned images, and high atomic resolution quality even when the STM is placed on the ground of the fifth floor without any external or internal vibration isolation devices

    2017-01-01

    Embedding of shape memory alloy (SMA) fibers into materials to fabricate SMA composites has attracted considerable attention because of the potential applicability of these composites in smart systems and structures. In this study, 2024Al matrix composites reinforced by continuous TiNi SMA fibers were fabricated using spark plasma sintering (SPS). The interface between the fibers and matrix consisted of a bilayer. The layer close to the fiber consisted of a multiple phase mixture, and the other layer exhibited a periodic morphology resulting from the alternating phases of Al 3 Ti and Al 3 Ni. In addition, a small quantity of TiO 2 phases was also observed in the interface layer. Based on detailed interface studies of the orientation relationships between the Al 3 Ti, Al 3 Ni, and TiO 2 phases and the atomic correspondence at phase boundaries, the effects of the interface phases on the fracture behavior of the composites were demonstrated.

    2010-09-01

    Full Text Available This article studies changes observed on the R-phase thermoelastic behavior in a near-equiatomic Ti-Ni shape memory alloy. Three kinds of procedures have been performed: different treatments, thermomechanical cycling under constant loading in shape memory helical springs and thermal cycling in as-treated and trained samples. Several heat treatments were carried out to investigate evolution of the R-phase by differential scanning calorimetry (DSC. A heat treatment was chosen on which R-phase is absent. Shape memory springs were produced and submitted to a training process in an apparatus by tensioning the springs under constant loading. Thermal cycling in DSC was realized in as-treated and trained samples. Several aspects of one-step (B2→B19' and two-steps (B2→R→B19' martensitic transformations and R-phase formation and their evolution during tests were observed and discussed.

  20. Effect of plastic strain on shape memory characteristics in sputter-deposited Ti-Ni thin films

    International Nuclear Information System (INIS)

    Nomura, K.

    1995-01-01

    The plastic strain which is introduced during cooling and heating under a constant stress has an influence upon the transformation and deformation characteristics of sputter-deposited Ti-Ni shape memory alloy thin films. With increasing the accumulated plastic strain, Ms rises and recovery strain increases. The changes in such characteristics are due to the internal stress field that is formed by plastic deformation. However, the change in Ms in Ti-50.5at%Ni is larger than that in Ti-48.9at%Ni, although the plastic strain in the former is lower than that in the latter. In order to understand this point, the effective internal stresses were estimated in both alloys; the internal stress in the former is more effectively created by the introduction of plastic strain than in the latter.

    2010-01-01

    The implantation and growth of metal nanoparticles on graphene nanosheets (GNS) leads directly to severe damage to the regular structure of the graphene sheets, which disrupts the extended π conjugation, resulting in an impaired device performance. In this paper, we describe a facile approach for achieving the lossless formation of graphene composite decorated with tiny cadmium sulfide quantum dots (QDs) with excellent nonlinear optical properties by using benzyl mercaptan (BM) as the interlinker. The mercapto substituent of BM binds to the CdS QDs during their nucleation and growth process, and then the phenyl comes into contact with the GNS via the π-π stacking interaction. Using this strategy, CdS QDs with an average diameter of 3 nm are uniformly dispersed over the surface of graphene, and the resulting QD-graphene composite exhibits excellent optical limiting properties, mainly contributed by nonlinear scattering and nonlinear absorption, upon both 532 and 1064 nm excitations, in the nanosecond laser pulse regime.

    This paper deals with the bulge process for forming the single-stage bellows of TiNi shape memory alloys, which is proposed as a new type of seismic applications, and especially considering the material's special behavior. Thin walled tubes with 20% cold work, whose composition is Ti-51.0 at% Ni, were prepared. First they are appropriately heat-treated and then the rubber bulge process is introduced for the tubes under the condition of austenite phase at room temperature. Displacement control method is adapted to the process. Theoretical prediction of change in outer diameter of the tube on compression is derived, and modified taking into account the progress of the stress-induced martensite transformation on tube's surface by observing the detachment of the oxide layer of the surface. Finally theoretical relationship between compressive displacement and the outer diameter of the tube, which is the most important for the design of the bellows shape, is cleared. (author)

    Patients suffering from postherpetic neuralgia often complain about hypo- or hypersensation in the affected dermatome. The loss of thermal sensitivity has been demonstrated by quantitative sensory testing as being associated with small-fiber (Aδ- and C-fiber) deafferentation. We aimed to compare laser stimulation (radiant heat) to thermode stimulation (contact heat) with regard to their sensitivity and specificity to detect thermal sensory deficits related to small-fiber dysfunction in postherpetic neuralgia. We contrasted detection rate of laser stimuli with 5 thermal parameters (thresholds of cold/warm detection, cold/heat pain, and sensory limen) of quantitative sensory testing. Sixteen patients diagnosed with unilateral postherpetic neuralgia and 16 age- and gender-matched healthy control subjects were tested. Quantitative sensory testing and laser stimulation of tiny skin areas were performed in the neuralgia-affected skin and in the contralateral homologue of the neuralgia-free body side. Across the 5 thermal parameters of thermode stimulation, only one parameter (warm detection threshold) revealed sensory abnormalities (thermal hypoesthesia to warm stimuli) in the neuralgia-affected skin area of patients but not in the contralateral area, as compared to the control group. In contrast, patients perceived significantly less laser stimuli both in the affected skin and in the contralateral skin compared to controls. Overall, laser stimulation proved more sensitive and specific in detecting thermal sensory abnormalities in the neuralgia-affected skin, as well as in the control skin, than any single thermal parameter of thermode stimulation. Thus, laser stimulation of tiny skin areas might be a useful diagnostic tool for small-fiber dysfunction. Copyright © 2012 International Association for the Study of Pain. Published by Elsevier B.V.

    Full Text Available Background: Quality communication skills and increased multicultural sensitivity are universal goals, yet teaching them have remained a challenge for educators. Objective: To document the process and participant responses to Interactive Theater when used as a method to teach physician-patient communication and cross-cultural competency. Design, setting, and participants: Three projects are reported. They were collaborations between Theater Delta, the UNC Center for Functional GI and Motility Disorders, the Rome Foundation, the World Gastroenterology Organization, and the American Gastroenterological Association. Outcome measures: 8 forced choice and 6 open ended were collected from each participant using a post-performance evaluation form. Results: Responses to the 8 indicators relating to a positive experience participating in the Interactive Theater. The vast majority either agreed or strongly agreed with the statements on the evaluation form. Written comments explained why. Conclusions: Data indicates that Interactive Theater stimulates constructive dialogue, analysis, solutions, and intended behavior change with regard to communication skills and adapting to patients from multicultural backgrounds. Interactive Theater directly focuses on communication itself (active listening, empathy, recognizing cultural differences, etc. and shows promise as an effective way to improve awareness and skills around these issues.

    Traditionally, surgical education has been confined to operating and lecture theaters. Access to the World Wide Web and services, such as YouTube and iTunes has expanded enormously. Each week throughout Ireland, nonconsultant hospital doctors work hard to create presentations for surgical teaching. Once presented, these valuable presentations are often never used again. We aimed to compile surgical presentations online and establish a new online surgical education tool. We also sought to measure the effect of this educational tool on surgical presentation quality. Surgical presentations from Cork University Hospital and Beaumont Hospital presented between January 2010 and April 2011 were uploaded to http://www.pilgrimshospital.com/presentations. A YouTube channel and iTunes application were created. Web site hits were monitored. Quality of presentations was assessed by 4 independent senior surgical judges using a validated PowerPoint assessment form. Judges were randomly given 6 presentations; 3 presentations were pre-web site setup and 3 were post-web site setup. Once uploading commenced, presenters were informed. A total of 89 presentations have been uploaded to date. This includes 55 cases, 17 journal club, and 17 short bullet presentations. This has been associated with 46,037 web site page views. Establishment of the web site was associated with a significant improvement in the quality of presentations. Mean scores for pre- and post-web site group were 6.2 vs 7.7 out of 9 respectively, p = 0.037. This novel educational tool provides a unique method to enable surgical education become more accessible to trainees, while also improving the overall quality of surgical teaching PowerPoint presentations.

    This work comprises a study of the influence of the pulse number of low-energy high-current electron beam (LEHCEB) exposure on the value and character of distribution of residual elastic stresses, texturing effects and the relationship between structural-phase states and physical and mechanical properties of the modified surface layers of TiNi alloy. LEHCEB processing of the surface of TiNi samples was carried out using a RITM-SP [3] installation. Energy density of electron beam was constant at E s = 3.9 ± 0.5 J/cm 2 ; pulse duration was 2.8 ± 0.3 μs. The number of pulses in the series was changeable, (n = 2–128). It was shown that as the result of multiple LEHCEB processing of TiNi samples, hierarchically organized multilayer structure is formed in the surface layer. The residual stress field of planar type is formed in the modified surface layer as following: in the direction of the normal to the surface the strain component ε ⊥ < 0 (compressing strain), and in a direction parallel to the surface, the strain component ε || > 0 (tensile deformation). Texturing effects and the level of residual stresses after LEHCEB processing of TiNi samples with equal energy density of electron beam (∼3.8 J/cm 2 ) depend on the number of pulses and increase with the rise of n > 10

    TiNi shape memory alloys (SMAs), used as long-term implant materials, have a disadvantage. Ni-ion release from the alloys may trigger allergies in the human body. Micro-arc oxidation has been utilized to modify the surface of the TiNi SMA for improving its corrosion resistance and biocompatibility. However, there are very few reports investigating the essential adhesive strength between the micro-arc oxidized film and TiNi SMA. Two primary goals were attained by this study. First, Ti50Ni48.5Mo1.5 SMA having a phase transformation temperature (Af) less than body temperature and good shape recovery were prepared. Next, the Ti50Ni50 and Ti50Ni48.5Mo1.5 SMA surfaces were modified by micro-arc oxidation in phosphoric acid by applying relatively low voltages to maintain the adhesive strength. The results indicated that the pore size, film thickness, and P content increased with applied voltage. The micro-arc oxidized film, comprising Ti oxides, Ni oxide, and phosphate compounds, exhibited a glassy amorphous structure. The outmost surface of the micro-arc oxidized film contained a large amount of P (>12 at%) but only a trace of Ni (micro-arc oxidized films exceeded the requirements of ISO 13779. Furthermore, Mo addition into TiNi SMAs was found to be favorable for improving the adhesive strength of the micro-arc oxidized film.

    Full Text Available The aim of this paper is to demonstrate how Jaques Rancière’s pedagogical theory, intellectual emancipation, esthetics and politics as used as a basis to understand the Theater of the Oppressed as a form of re-distribution of the sensible inside contemporary society. The Theater of the Oppressed practices, able to provide social and political emancipation with esthetical resources, can renew the ways of sensible appropriation, as well as the snip of this appropriation. The “intelligentsia equality” assumption, allied to several mechanisms that can give the oppressed people the artistic means of production, will be exposed here as a voice capable of answering the contemporary challenges of political emancipation. This article has the intention to articulate an interdisciplinary perspective, because it works with conceptions from politics, philosophy, theater and education.

    Sacral Theater has been developed for the toroid magnet Atlas of the CERN LHC project. This three dimensional calculations code calculates the propagation of the transition of a superconducting coil in 25 m long hippodrome. Procedures to study low currents have been included. This work is a part of the magnet safety system because the coils protection is made by warmers activating the quench propagation in case of default detection. This allows the complete dissipation of storage energy that can reach 1080 MJ on Atlas. (N.C.)

    Undertaking an examination of the precarious places of the movies and movie theaters in queer lives in the 20th century, this article takes up a series of anecdotal episodes and feature-length films to consider how the space-related stakes of LGBT health have been best understood in literal cinema houses and the narrative cinema projections inside of them. The author argues for an appreciation of LGBT-themed motion pictures as oscillating between perpetuator of queer pathology and its potential solution.

    Full Text Available The aim of the study was to know the response of the relatives attending the squint surgery of their ward. A trained secretary administered an eight item questionnaire by live / telephonic interview. Of the 44 attendees, two left the Operation Theater before completion of the surgery. Mean age of the patients was 7.2 years ± 7.8 and that of the attendees was 36.1 years ± 8.5. Forty patients had a surgery under general anesthesia and four under local anesthesia. Eleven (25% attendees experienced an increase in anxiety. Thirty-six (82% attendees reported increased transparency, 38 (86% reported increased confidence, and 43 (98% reported increased awareness. None found any disadvantage. Twenty-seven (61% recommended this practice for all and 16 (36% recommended the practice selectively. The internal validity of the questionnaire was fair (Cronbach′s Alpha = 0.6. It was concluded that the presence of relatives in the Operation Theater during the surgery could bring in more transparency, accountability, confidence, awareness, and trust.

    Sun protection in childhood is important to reduce the risk of developing skin cancer later in life. The "Periods-of-Life-Program" for primary prevention of skin cancer introduces a combination of individual and environmental interventions for the preschool period. Within this pilot study, an intervention group received cognitive-behavioral and environmental interventions. A control group had solely received the environmental intervention, and a wait-control group received no intervention. Nursery school children (n = 80, 3 to 6 years of age) of four nursery schools were randomly assigned to these groups on school level. The ability of the cognitive-behavioral intervention (a theater play) to enhance sun protection knowledge was examined. The theater play improved knowledge over all age groups (p < .05 η(2) = .06). Age-specific analyses showed better results for children aged 5 to 6 (p < .05 η(2) = .20) compared to children aged 3 to 4 years (p = .17 η(2) = .04). In combining cognitive-behavioral and environmental interventions, the "Periods-of-Life-Program" is a promising strategy for primary prevention of skin cancer.

    Exposure therapy (ET) has been observed to be an effective modality for the treatment of combat-related posttraumatic stress disorder (PTSD). Recently, efforts have been made to use virtual reality (VR) to enhance outcome with modes of ET. How such therapy applies to service members who are facing the reality of a combat deployment has been unknown. This case series documents the first use of VR-based therapy to the treatment of PTSD in a combat theater. Results of therapy are reported from a mental health clinic in Camp Fallujah, Iraq. Combat PTSD constituted a relatively small percentage of overall mental health patients seen. Those who did present with PTSD were offered VR-based ET or traditional ET. Patients who received either treatment modality showed significant gains, and no service member in treatment had to be medically evacuated because of ongoing PTSD symptoms. This demonstrates that ET, with or without the use of VR, can be an effective means of helping service members with mental health issues while they serve in theater.

    Pregnant African American women are at disproportionately high risk of premature birth and infant mortality, outcomes associated with cigarette smoking. Telephone-based, individual smoking cessation counseling has been shown to result in successful quit attempts in the general population and among pregnant women, but "quitlines" are underutilized. A social marketing campaign called One Tiny Reason to Quit (OTRTQ) promoted calling a quitline (1-800-QUIT-NOW) to pregnant, African American women in Richmond, Virginia, in 2009 and was replicated there 2 years later. The campaign disseminated messages via radio, interior bus ads, posters, newspaper ads, and billboards. Trained volunteers also delivered messages face-to-face and distributed branded give-away reminder items. The number of calls made from pregnant women in the Richmond area during summer 2009 was contrasted with (a) the number of calls during the seasons immediately before and after the campaign, and (b) the number of calls the previous summer. The replication used the same evaluation design. There were statistically significant spikes in calls from pregnant women during both campaign waves for both types of contrasts. A higher proportion of the calls from pregnant women were from African Americans during the campaign. A multimodal quitline promotion like OTRTQ should be considered for geographic areas with sizable African American populations and high rates of infant mortality.

    Embedding of shape memory alloy (SMA) fibers into materials to fabricate SMA composites has attracted considerable attention because of the potential applicability of these composites in smart systems and structures. In this study, 2024Al matrix composites reinforced by continuous TiNi SMA fibers were fabricated using spark plasma sintering (SPS). The interface between the fibers and matrix consisted of a bilayer. The layer close to the fiber consisted of a multiple phase mixture, and the other layer exhibited a periodic morphology resulting from the alternating phases of Al{sub 3}Ti and Al{sub 3}Ni. In addition, a small quantity of TiO{sub 2} phases was also observed in the interface layer. Based on detailed interface studies of the orientation relationships between the Al{sub 3}Ti, Al{sub 3}Ni, and TiO{sub 2} phases and the atomic correspondence at phase boundaries, the effects of the interface phases on the fracture behavior of the composites were demonstrated.

    2011-01-01

    This paper reports the rapid thermal annealing (RTA) of Ti-rich TiNi thin films, synthesized by the co-sputtering of TiNi and Ti targets. Long-range order of aperiodic alloy could be achieved in a few seconds with the optimum temperature of 773 K. Longer annealing (773 K/240 s), transformed the film to a poorly ordered vitreous phase, suggesting a novel method for solid state amorphization. Reitveld refinement analyses showed significant differences in structural parameters of the films crystallized by rapid and conventional thermal annealing. Dependence of the elastic modulus on the valence electron density (VED) of the crystallized films was studied. It is suggested that RTA provides a new approach to fabricate patterned shape memory thin films.

    Full Text Available Vicia hirsuta (L. Gray S.F. (tiny vetch is a common and persistent segetal weed. Tiny vetch seeds and pods reach different stages of maturity during the crop harvest season. Some seeds that mature before cereal harvest are shed in the field and deposited in the soil seed bank, while others become incorporated into seed material. The objective of this study was to describe selected aspects of tiny vetch seed ecology: to determine the rate of individual reproduction of vetch plants growing in winter and spring grain crops and to evaluate the germination of seeds at different stages of maturity, subject to storage conditions. The seeds and pods of V. hirsuta were sorted according to their development stages at harvest and divided into two groups. The first group was stored under laboratory conditions for two months. In the autumn of the same year, the seeds were subjected to germination tests. The remaining seeds were stored in a storeroom, and were planted in soil in the spring. The germination rate was evaluated after 8 months of storage. Potential productivity (developed pods and flowers, fruit buds was higher in plants fruiting in winter wheat than in spring barley. Vetch plants produced around 17-26% more pods (including cracked, mature, greenish-brown and green pods and around 25% less buds in winter wheat than in spring barley. Immature seeds were characterized by the highest germination capacity. Following storage under laboratory conditions and stratification in soil, mature seeds germinated at a rate of several percent. After storage in a storeroom, seeds at all three development stages broke dormancy at a rate of 72- 75%. The high germination power of tiny vetch seeds stored in a storeroom indicates that this plant can be classified as an obligatory speirochoric weed species.

    Full Text Available Worldwide, one in every three species of amphibian is endangered, 39 species have gone extinct in the last 500 years and another 130 species are suspected to have gone extinct in recent decades. Of the amphibians, salamanders have the highest portion of their species in one of the risk categories, even higher than the frogs. To date there have been few studies that have used recent field data to examine the status of populations of endangered salamanders. In this study we evaluate the current situation of two tiny salamanders, Parvimolge townsendi and Thorius pennatulus, both of which are distributed at intermediate elevations in the mountains of the northern Neotropics and are considered to be critically endangered; the first has been proposed as possibly extinct. By carrying out exhaustive surveys in both historical and potentially suitable sites for these two species, we evaluated their abundance and the characteristics of their habitats, and we estimated their potential geographic distribution. We visited 22 sites, investing 672 person-hours of sampling effort in the surveys, and found 201 P. townsendi salamanders in 11 sites and only 13 T. pennatulus salamanders in 5 sites. Both species were preferentially found in cloud forest fragments that were well conserved or only moderately transformed, and some of the salamanders were found in shade coffee plantations. The potential distribution area of both species is markedly fragmented and we estimate that it has decreased by more than 48%. The results of this study highlight the importance of carrying out exhaustive, systematic field surveys to obtain accurate information about the current situation of critically endangered species, and help us better understand the crisis that amphibians are facing worldwide.

    We present Feedback in Realistic Environment (FIRE)/GIZMO hydrodynamic zoom-in simulations of isolated dark matter haloes, two each at the mass of classical dwarf galaxies (Mvir ≃ 1010 M⊙) and ultra-faint galaxies (Mvir ≃ 109 M⊙), and with two feedback implementations. The resulting central galaxies lie on an extrapolated abundance matching relation from M⋆ ≃ 106 to 104 M⊙ without a break. Every host is filled with subhaloes, many of which form stars. Each of our dwarfs with M⋆ ≃ 106 M⊙ has 1-2 well-resolved satellites with M⋆ = 3-200 × 103 M⊙. Even our isolated ultra-faint galaxies have star-forming subhaloes. If this is representative, dwarf galaxies throughout the Universe should commonly host tiny satellite galaxies of their own. We combine our results with the Exploring the Local Volume in Simulations (ELVIS) simulations to show that targeting ˜ 50 kpc regions around nearby isolated dwarfs could increase the chances of discovering ultra-faint galaxies by ˜35 per cent compared to random pointings, and specifically identify the region around the Phoenix dwarf galaxy as a good potential target. The well-resolved ultra-faint galaxies in our simulations (M⋆ ≃ 3-30 × 103 M⊙) form within Mpeak ≃ 0.5-3 × 109 M⊙ haloes. Each has a uniformly ancient stellar population ( > 10 Gyr) owing to reionization-related quenching. More massive systems, in contrast, all have late-time star formation. Our results suggest that Mhalo ≃ 5 × 109 M⊙ is a probable dividing line between haloes hosting reionization `fossils' and those hosting dwarfs that can continue to form stars in isolation after reionization.

    It is important to distinguish small lesions with increased arterial perfusion observed by computed tomographic arteriography (CT-A) from hepatocellular carcinoma (HCC). However, the clinical characteristics and prognosis of such lesions have not been clarified. We retrospectively examined 200 patients with cirrhosis related to hepatitis C virus (HCV) infection who had undergone both CT-A and CT arterioportography between 1995 and 1998, and found 80 tiny staining spots (TSS)s, with a diameter of 5-10 mm, by CT-A (35 patients). The mean TSS observation period was 29.0 months. If the major axis was larger than 10 mm and showed a 1.5-fold or more increase, the lesion was regarded as tumor growth (TG). The TSS lesions were divided into two groups according to whether the patient had or did not have HCC. The prognosis of TSS was classified into three groups; HCC-suspected group, nontumor group, and unclassified group, in which TG was negative although transcatheter arterial embolization (TAE) had been performed. Of the 40 TSSs in 14 patients without HCC, 2 (5%) were suspected as HCC. Of the 40 TSSs in 21 patients with HCC, 13 (32.5%) were suspected as HCC. There were no significant differences in the size, position, and morphology of TSSs among the three prognostic groups. Of the 7 TSSs with a high signal intensity on T2-weighted magnetic resonance (MR) images, 5 were in the HCC-suspected group. We recommend early treatment of TSSs accompanying HCC or showing features of malignancy at the imaging workup. (author)

    The harmful effects of noise exposure during leisure-time activities are beginning to receive some scrutiny. We conducted a preliminary study to investigate the noise levels during the showings of 25 different films. During each screening, various sound measurements were made with a dosimeter. The movies were classified on the basis of both their Motion Picture Association of America (MPAA) rating and their genre, and the size of the theater and the size of the audience were taken into consideration in the final analysis. Our findings suggest that the sound levels of many movies might be harmful to hearing, although we can draw no definitive conclusions. We did not discern any relationship between noise levels and either MPAA rating or genre. Further studies are recommended.

    Stewart-Parker, Emma; Galloway, Robert; Vig, Stella

    Possessing adequate nontechnical skills (NTS) in operating theaters is of increasing interest to health care professionals, yet these are rarely formally taught. Teams make human errors despite technical expertise and knowledge, compromising patient safety. We designed a 1-day, multiprofessional, multidisciplinary course to teach, practice, and apply these skills through simulation. The course, "S-TEAMS," comprised a morning of lectures, case studies, and interactive teamworking exercises. The afternoon divided the group into multiprofessional teams to rotate around simulated scenarios. During the scenarios, teams were encouraged to focus on NTS, including communication strategies, situational awareness, and prompts such as checklists. A thorough debrief with experienced clinician observers followed. Data was collected through self-assessments, immediate and 6-month feedback to assess whether skills continued to be used and their effect on safety. In total, 68 health care professionals have completed the course thus far. All participants felt the course had a clear structure and that learning objectives were explicit. Overall, 95% felt the scenarios had good or excellent relevance to clinical practice. Self-assessments revealed a 55% increase in confidence for "speaking up" in difficult situations. Long-term data revealed 97% of the participants continued to use the skills, with 88% feeling the course had prevented them from making errors. Moreover, 94% felt the course had directly improved patient safety. There is a real demand and enthusiasm for developing NTS within the modern theater team. The simple and easily reproducible format of S-TEAMS is sustainable and inclusive, and crucially, the skills taught continue to be used in long term to improve patient safety and teamworking.

    Full Text Available O objetivo deste artigo é promover uma discussão sobre psicologia e teatro, buscando compreender algumas relações e efeitos possíveis quando ambos se aproximam e se voltam para a produção de subjetividade nas comunidades populares. Um conceito central é o de partilha do sensível, formulado por Jacques Rancière. O texto discute as formas que a partilha do sensível configura tanto no teatro quanto na psicologia comunitária quando estes se propõem a ser vetores da transformação social, e aponta entraves quando estes se limitam à representação convencional dos conflitos sociais. Outro aspecto considerado é a necessidade de dar mais relevo aos processos de produção de desejo na comunidade.This essay aims to discuss psychology and theater, their relations and possible effects when they are both involved with the production of subjectivity in popular communities. One main concept is the distribution of the sensible, created by Jacques Rancière. The text analyses the distribution of the sensible performed by the theater and by community psychology when they search social transformation. This study's conclusions indicate that the persistence of the conventional representation of the social conflicts constitutes an obstacle shared by psychology and theater, and point to the necessity of giving more relevance to the production of desire in the community.

  12. Exogenously applied D-pinitol and D-chiro-inositol modifies the accumulation of α-D-galactosides in developing tiny vetch (Vicia hirsuta [L.] S.F. Gray seeds

    Full Text Available In the present study we have investigated the effect of exogenous cyclitols on the accumulation of their galactosides and raffinose family oligosaccharides (RFOs, as well as on some enzymes important for their biosynthesis in seeds of tiny vetch (Vicia hirsuta [L.] S.F. Gray. Immature seeds during 6-day incubation with D-chiro-inositol (naturally does not appear in seeds of tiny vetch were accumulated cyclitol and its galactosides (fagopyritols: B1 and B2. Short 4-hour incubation with D-chiro-inositol, and subsequent slow desiccation process caused accumulation of free cyclitol only, without biosynthesis of its galactosides. Feeding D-chiro-inositol to pods of tiny vetch induced accumulation of high levels of its galactosides (fagopyritol B1, B2 and B3 in maturing seeds. Similarly, feeding D-pinitol increased accumulation of its mono-, di- and tri-galactosides: GPA, GPB, DGPA and TGPA in tiny vetch seed. Accumulation of both cyclitols and their galactosides drastically reduced accumulation of verbascose. Inhibition of RFOs biosynthesis by elevated levels of free cyclitols suggests some competition between formation of both types of galactosides and similarity of both biosynthetic routes in tiny vetch seeds. Galactinol synthase (GolS from tiny vetch seeds demonstrated ability to utilize D-chiro-inositol as galactosyl acceptor, instead of myo-inositol. Presence of both cyclitols, as substrates for GolS, caused synthesis of their galactosides: fagopyritol B1 and galactinol. However, formation of galactinol was more efficient than fagopyritol B1. D-chiro-Inositol and D-pinitol at concentrations several-fold higher than myo-inositol had inhibitory effect on GolS. Thus, we suggest that a level of free cyclitols can have an influence on the rate of galactinol biosynthesis and further accumulation of RFOs and galactosyl cyclitols in tiny vetch seeds.

    Full Text Available We propose a comprehensive sensing platform called SenStick, which is composed of hardware (ultra tiny all-in-one sensor board, software (iOS, Android, and PC, and 3D case data. The platform aims to allow all the researchers to start IoT research, such as activity recognition and context estimation, easily and efficiently. The most important contribution is the hardware that we have designed. Various sensors often used for research are embedded in an ultra tiny board with the size of 50 mm (W × 10 mm (H × 5 mm (D and weight around 3 g including a battery. Concretely, the following sensors are embedded on this board: acceleration, gyro, magnetic, light, UV, temperature, humidity, and pressure. In addition, this board has BLE (Bluetooth low energy connectivity and capability of a rechargeable battery. By using 110 mAh battery, it can run more than 15 hours. The most different point from other similar boards is that our board has a large flash memory for logging all the data without a smartphone. By using SenStick, all the users can collect various data easily and focus on IoT data analytics. In this paper, we introduce SenStick platform and some case studies. Through the user study, we confirmed the usefulness of our proposed platform.

    The modified fundamental measure theory (MFMT) has been employed to investigate the effects of inserting a tiny sphere in the center of a nanospherical pore on the structure, adsorption, and capillary condensation of fluids confined in it. In the first part of this Article, we have solved the weighted density integrals for all pores with spherical symmetries, including spherical and bispherical pores. In the second part, we show that the structure, amount of adsorption, and position of the fluid's capillary condensation change drastically when even a very thin sphere, R(s) = 0.01σ, is inserted into the center of a spherical pore (SP). In fact, the existence of a forbidden region around the inner sphere for the case of bispherical pores, even when R(s) = 0.01σ, causes a remarkable shift in both the amount of adsorption and the bulk density at which the capillary condensation occurs. Moreover, the insertion causes a sudden increase in the value of the contact density of the liquid, or the liquid in equilibrium with its vapor, at the wall of the outer sphere compared to that for an SP. In other words, the insertion of a tiny sphere in an SP causes the liquid droplet, which is formed in the center of the SP, to sprinkle throughout the whole nanopore. Also, we have demonstrated that the critical temperature and densities decrease with decreasing radius of the inner sphere.

    Novel well-dispersed tiny Bi2S3 nanoparticles (NPs) with an average sizes of approximately 16.2 nm were used to decorate layered g-C3N4 nanosheets (NSs), with the purpose of constructing highly efficient 0D/2D heterojunction photocatalyst by a simple hydrothermal method in one step. The fabricated Bi2S3/g-C3N4 heterostructures exhibited superior visible-light-driven photocatalytic activity toward methyl orange (MO) degradation in contrast to that of individual Bi2S3 and g-C3N4, which could be mainly ascribed to the synergistic effect of the tiny size effect of 0D Bi2S3 NPs and 2D g-C3N4 NSs, the matched energy level positions, and the abundant coupling heterointerfaces between two moieties. More importantly, the photodegradation of methylene blue (MB), rhodamine B (RhB) and colorless tetracycline (TC), ciprofloxacin (CIP) further revealed the broad-spectrum photodegradation capacities of the heterojunction materials. The possible photoinduced charge transfer and pollutant degradation process over Bi2S3/g-C3N4 heterojunctions under visible-light irradiation were proposed. This work may provide a platform for constructing new visible light 0D/2D intimate contact heterostructures with stable and efficient photocatalytic performance.

    To provide the advanced interventional procedure of zygapophysial joint neurotomy to soldiers meeting the diagnostic criteria in a combat environment and thus reduce medical evacuations of soldiers from a theater of war. Retrospective chart review was performed on three consecutive soldiers who received neuroablation of the lumbar ZP joint. Patients received single MBB with 1 cc of 1% lidocaine at the b/l L3-L5 levels considered diagnostic if >50% analgesia was achieved concordant with duration of anesthetic.   All procedures were co-performed by the two authors at the Ibn Sina hospital in Baghdad, Iraq over a 3-month period. Three consecutive patients with >50% pain relief from diagnostic medial branch blocks were treated with radiofrequency ablation of the bilateral L3-L4 medial branch nerves and L5 posterior primary ramus. Sensory test stimulation at 50 Hz and motor stimulation at 2 Hz were performed at each level. The nerves were then lesioned at 80° Centigrade for 90 seconds after injection of lidocaine and methylprednisolone. Procedure was considered successful if patients were able to wear body armour without significant discomfort (at least 1 hour/day). Medical evacuation from Iraq was prevented and all soldiers returned to rigorous combat duties including the wearing of body armour daily. We believe to be the first to report on the use of RF nerve ablation in a war time setting and with this functional outcome. Wiley Periodicals, Inc.

    This paper describes a study conducted by the National Laboratory for Civil Engineering of Portugal (LNEC), in cooperation with the Defense University Center at the Spanish Naval Academy and "La Sapienza," University of Rome, to assess the health and safety conditions of the Noble Hall floor in the São Carlos National Theater (Lisbon, Portugal). In a multidisciplinary approach, extensive fieldwork was carried out. The survey included the location and characterization of beams in the various areas of the floor by using two ground penetrating radar (GPR) systems equipped with two different ground- or air-coupled antennas, local inspection openings to visually assess the geometry, timber species and conservation state of structural members, and an assessment of the conservation state of the timber beam ends using drilling equipment. All the tests performed and the results obtained are presented. The potential of using non-destructive tests for the inspection of timber cultural heritage structures, particularly GPR, is discussed, and some practical recommendations are made.

  18. Science as theater, theater as science

    Beginning with Bertold Brecht's "Galileo" in 1942 and Friedrich Dürrenmatt's "The Physicists" in 1962, physics and other sciences have served a number of dramatists as backdrops for the exposition of existential problems, as well as the provision of entertainment. Michael Frayn's 1998 play "Copenhagen" broke new ground by giving a central role to the presentation of scientific substance and ideas and to the examination of recent controversial and emotionally charged events in the history of science and of the "real world". A rash of "science plays" erupted. How should we physicists react to this development? Surely, it can be argued, any exposure of science to the public is better than none and will help break down the barriers between the "two cultures". But what if the science or the scientists are badly misrepresented or the play is a weapon to strip science of its legitimacy and its claims to reality and truth? After reviewing a half dozen of the new plays, I conclude that "Copenhagen", though flawed, is not only the best of show, but a positive, even admirable endeavor. The contributions of Bohr, Heisenberg, Born, Schrödinger, and other scientists and their interactions in the golden years of the creation of quantum mechanics are accurately and thrillingly rendered. There may be no better non-technical exposition of complementarity and the uncertainty principle than the one that Frayn puts into the mouths of Bohr and Heisenberg. The treatment of the history of the atomic bomb and Heisenberg's role in Germany's failure to achieve a bomb is another matter. Frayn can also be criticized for applying uncertainly and complementarity to the macroscopic world and, in particular, to human interactions, thereby giving some aid and comfort to the post-modernists. These reservations aside, Copenhagen is a beautiful contribution to the appreciation of science.

    Accidental exposures to blood of body fluids (ABE) expose health care workers (HCW) to the risk of occupational infection. Our aim was to assess the prevention equipment available in the operating theater (OT) with reference to guidelines or recommendations and its use by the staff in that OT on that day and past history of ABE. Correspondents of the Centre de Coordination de la Lutte contre les Infections Nosocomiales (CCLIN) Paris-Nord ABE Surveillance Taskforce carried out an observational multicenter survey in 20 volunteer French hospitals. In total, 260 operating staff (including 151 surgeons) were investigated. Forty-nine of the 260 (18.8%) staff said they double-gloved for all patients and procedures, changing gloves hourly. Blunt-tipped suture needles were available in 49.1% of OT; 42 of 76 (55.3%) of the surgeons in these OT said they never used them. Overall, 60% and 64% of surgeons had never self-tested for HIV and hepatitis C virus (HCV), respectively. Fifty-five surgeons said they had sustained a total of 96 needlestick injuries during the month preceding the survey. Ten of these surgeons had notified of 1 needlestick injury each to the occupational health department of their hospital (notification rate, 10.4%). The occurrence of needlestick injury remained high in operating personnel in France in 2000. Although hospitals may improve access to protective devices, operating staff mindful of safety in the OT should increase their use of available devices, their knowledge of their own serostatus, and their ABE notification rate to guide well-targeted prevention efforts.

    Simulation has been used as a learning tool in different disciplines and professions, including medicine and its specialties. Its usefulness is directly related to the integration of objectives, contents, methodologies and specific resources in each area of knowledge. To describe the development of an educational experience implemented in the Pontificia Universidad Javeriana Cali (Cali, Colombia) with medical students of Human Behavior II program, between 2012 and 2013. This experience was performed with simulated patients played by actors of the Altergesto theater group, that were interviewed by students under the supervision of psychiatrists and teachers of the subject, using the Simulated Hospital of the University. A historical development recall of the teaching sequence was made from the first half of 2012 to the second half of 2013, a statement of pedagogical objectives, and a description of the teaching-learning strategies. 158 interviews were conducted over a period of two years during which it was necessary to raise methodological solutions to adapt this teaching sequence to the content and objectives of the subject. The high-fidelity simulation, integrating actors who represent psychiatric patients mixed with the technology of a Simulated Hospital was useful to achieve compliance with the objectives proposed in the course of Human Behavior II, as a part of the program of Medicine at the Pontificia Universidad Javeriana Cali. In parallel, the construction of experience as an interdisciplinary project and the practical approach of this strategy may impact on cognitive, emotional, behavioral dimensions of the participants, encouraging meaningful learning. An easy access database for the collected material and the study of the effects of this strategy in the formation of long-term students is needed.

    The TiNi- and CuAl-based shape memory alloy thin films and wear/corrosion resistant surface coats have been produced by the ion-plasma deposition method with an arc dispersion of the cathode/target. This technique was widely used for production of the coats from a sprayed pure metal or a single-phase alloy. We have offered to use this process for dispersion of the heterophase alloys like shape memory alloys. The arguments for choosing of this technique are discussed with respect to creation of the conditions for preservation not only chemical composition, but also phase structure of an alloy in a covering, thus the shape memory/superelastic effects to be kept in a coat.

    In this work, the effect of electrothermal annealing on the transformation characterization of TiNi shape memory alloy and the electrothermal actuating characteristics of a two-way shape memory effect (TWSME) extension spring were investigated with direct electrical current. The results showed that with increasing direct electrical current density, the B2→R-phase transformation shifts to a lower temperature and R-phase→B19' shifts to a higher temperature in the cooling process. When annealing electrical current density reached 12.2 A/mm 2 , the R-phase disappeared and austenite transformed into martensite directly. The electrothermal annealing was an effective method of heat treatment in a selected part of shape memory alloy device. The electrothermal actuating characteristics of a TWSME spring showed that the time response and the maximum elongation greatly depended on the magnitude of the electrical current

    Full Text Available The role of the abscisic acid (ABA in biosynthesis of raffinose family oligosaccharides (RFOs and galactosyl cyclitols (Gal-C in tiny vetch (Vicia hirsuta [L.] S.F. Gray seeds was investigated. The ABA was applied through incubation of seed at various stage of its development. The level of RFOs and Gal-C was determined in seed maturing on plant and in seed maturing in vitro. In early stages of V. hirsuta seed development, the ABA activated the biosynthesis of galactinol, although the level of arisen galactinol quickly declined. In the later stages of V. hirsuta seed development ABA had stimulatory effect of RFOs and Gal-C biosynthesis. Influence of ABA on biosynthesis of a-galactosides in Vicia hirsuta seed seems to be dependent on abscisic acid concentration. Low concentration of ABA had stimulatory effect on a-galactosides biosynthesis, but high concentration of ABA inhibited the process.

    Introduction To evaluate the relative effectiveness of tsetse control methods, their costs need to be analysed alongside their impact on tsetse populations. Very little has been published on the costs of methods specifically targeting human African trypanosomiasis Methodology/Principal Findings In northern Uganda, a 250 km2 field trial was undertaken using small (0.5 X 0.25 m) insecticide-treated targets (“tiny targets”). Detailed cost recording accompanied every phase of the work. Costs were calculated for this operation as if managed by the Ugandan vector control services: removing purely research components of the work and applying local salaries. This calculation assumed that all resources are fully used, with no spare capacity. The full cost of the operation was assessed at USD 85.4 per km2, of which USD 55.7 or 65.2% were field costs, made up of three component activities (target deployment: 34.5%, trap monitoring: 10.6% and target maintenance: 20.1%). The remaining USD 29.7 or 34.8% of the costs were for preliminary studies and administration (tsetse surveys: 6.0%, sensitisation of local populations: 18.6% and office support: 10.2%). Targets accounted for only 12.9% of the total cost, other important cost components were labour (24.1%) and transport (34.6%). Discussion Comparison with the updated cost of historical HAT vector control projects and recent estimates indicates that this work represents a major reduction in cost levels. This is attributed not just to the low unit cost of tiny targets but also to the organisation of delivery, using local labour with bicycles or motorcycles. Sensitivity analyses were undertaken, investigating key prices and assumptions. It is believed that these costs are generalizable to other HAT foci, although in more remote areas, with denser vegetation and fewer people, costs would increase, as would be the case for other tsetse control techniques.

The samples were excited by 22.69 keV X-rays from a 10 mCi Cd-109 radioactive point source and K X rays emitted by samples were counted by a high resolution Si(Li solid-state detector coupled to a 4 K multichannel analyzer (MCA. The alloying effects on the X-ray fluorescence (XRF parameters of Ti-Ni shape memory alloys (SMAs were investigated. It is clearly observed that alloying effect causes to change in K shell XRF parameter values in Ti-Ni based SMAs for different compositions of x. Also, the present investigation makes it possible to perform reliable interpretation of experimental σKα, σKβ and ωK values for Ti and Ni in SMAs and can also provide quantitative information about the changes of K shell X-ray fluorescence cross sections and fluorescence yields of these metals with alloy composition.

    In order to improve the rate performance of MoO3, a novel MoO3 nanobelt with tiny grains on surface (named as d-MoO3) is fabricated via one-step facile hydrothermal method with citric acid adding, in which citric acid (CA) serves as a weak reductant as well as surface modification agent. When tested as an anode in LIBs, d-MoO3 displays an improved discharge capacity of 787 mAh·g-1 at 0.1 A g-1 over 100 cycles with capacity retention of ∼91% while MoO3 decays to 50 mAh·g-1 in the 100th cycle. Notably, d-MoO3 delivers enhanced rate capability (536 and 370 mAh·g-1 at high rates of 5 and 10 A g-1 respectively). We consider these excellent electrochemical properties of d-MoO3 electrode are associated with the tiny grains on MoO3 surface, which effectively maintains the electrode's structural integrity. Even though d-MoO3 nanobelt suffers from a degree of in-situ pulverization after several cycles, these pulverized active particles can still maintain stable electrochemical contact and are highly exposed to electrolyte, realizing ultrahigh e-/Li+ diffusion kinetics. In addition, part extrinsic pseudocapacitance contribution to the Li+ storage also explains the high-rate performance. Combining all these merits, d-MoO3 is potentially a high-energy, high-power and well-stable anode material for Li ion batteries (LIBs).

  8. TiNi shape memory alloys: effects of the fabrication route, the oxygen content and the zirconium or hafnium additions on the metallurgical characteristics and the thermomechanical properties

    1996-01-01

    In order to promote the development of Ti-Ni shape memory alloys, we have studied the correlation between the fabrication route, the chemical composition (O 2 content, Zr or Hf additions), the metallurgical characteristics and the thermomechanical properties. A conventional sintering does not allow to obtain a homogeneous compound of pure Ti 50 Ni 50 alloy because of the occurrence of Kirkendall porosities which act as a diffusion barrier. An original process including combustion synthesis and hot-extrusion was successfully developed. Resulting products exhibit a smaller grain size (15-20μm) and an enhanced workability in comparison with products obtained by arc-melting and subsequent hot rolling. The presence of oxygen in equiatomic Ti-Ni alloy induces the oxide precipitation of Ti 4 Ni 2 O x type (with x ≤ 1). The precipitated particle fraction is proportional to the oxygen nominal content of the alloy. We show that the decrease of the transformation temperatures is correlated with the decrease of Ti in solid solution due to Ti 4 Ni 2 O precipitation. Moreover, we find that a fine and homogenous oxide dispersion is suitable to decrease the grain size during hot rolling and to enhance to the one way shape memory properties. An increase of the typical transformation temperatures is obtained through of Zr or Hf (in substitution to Ti). But, an increase of the hardness is measured, and consequently the workability of the ternary alloys becomes reduced. However, it is worthwhile to point out that a Ti 38 Ni 50 Hf 12 product obtained by arc melting and hot extrusion is able to fully recover an apparent plastic strain of more than 4% during tensile tests performed under special loading conditions. Such as behaviour is of great interest with respect to potential applications in a temperature range higher that 100 deg. C. (author)

En décembre 1952, l’opéra Carmen a été diffusé en direct depuis le Metropolitan Opera de New York dans 31 salles de 26 villes différentes. Le gala d’ouverture de l’Opéra en 1954 a même été transmis dans un réseau de salles encore plus étendu. Envisagé au départ comme un complément régulier de la programmation des salles, le contenu hors film fera finalement l’objet d’une exploitation plutôt événementielle. Les exploitants (notamment de circuits importants n’installeront finalement l’équipement nécessaire que pour les transmissions justifiant la dépense. La numérisation du parc de salles américain et mondial appelle aujourd’hui à réexaminer les stratégies de programmation de contenus hors film dans les années 1950 et à revoir le discours de la 20th Century–Fox au sujet des possibilités ouvertes par la diffusion électronique. Cet article a pour objectif d’étudier l’un des chapitres les moins connus de l’histoire de l’exploitation cinématographique aux Etats-Unis. En effet, à la lumière des évolutions contemporaines dans le domaine des médias numériques, cette première tentative d’introduction à grande échelle d’une forme de distribution dématérialisée de contenus film et hors film vers les salles de cinéma rev

    To evaluate the clinical course of disappearing colorectal liver metastases (DLM) or residual tiny (≤5 mm) colorectal liver metastases (RTCLM) on gadoxetic acid-enhanced magnetic resonance imaging (MRI) and diffusion-weighted imaging (DWI) in patients who had colorectal liver metastases (CLM) and received chemotherapy. Among 137 patients who received chemotherapy for CLM and underwent gadoxetic acid-enhanced MRI and DWI between 2010 and 2012, 43 patients with 168 DLMs and 48 RTCLMs were included. The cumulative in situ recurrence rate of DLM and progression rate of RTCLM and their predictive factors were evaluated. A total of 150 DLMs and 26 RTCLMs were followed up without additional treatment. At 1 and 2 years, respectively, the cumulative in situ recurrence rates for DLM were 10.9 % and 15.7 % and the cumulative progression rates for RTCLM were 27.2 % and 33.2 %. The in situ recurrence rate at 2 years was 4.9 % for the DLM group that did not show reticular hypointensity of liver parenchyma on hepatobiliary phase. DLM on gadoxetic acid-enhanced liver MRI and DWI indicates a high possibility of clinical complete response, especially in patients without chemotherapy-induced sinusoidal obstruction syndrome. Thirty-three percent of RTCLMs showed progression at 2 years. (orig.)

    The shape of a dew droplet deposited on the mirror surface of a copper plate was measured accurately using an interference microscope that employed a phase-shift technique. The microscope was constructed by adding a piezoelectric transducer to an interference microscope. A simple method that uses a conventional speaker horn and an optical fibre cable was used to depress any speckle noise. The shape of a dew droplet deposited at dew point on the plate surface with average roughness of 0.1 µm was measured with an accuracy of ± 3 nm. The mass of a tiny dew droplet could be determined from the volume of its shape and was of the order of 10-9 g. The total mass of a dew droplet deposited per unit area and the deposition velocity under a gentle wind were also obtained in a similar way. The total mass was of the order of 10-5 g cm-2 at the beginning of deposition and the deposition velocity ranged from 1 × 10-5 to 6 × 10-5 g cm-2 min-1 at room temperature.

  12. Development of transformation bands in TiNi SMA for various stress and strain rates studied by a fast and sensitive infrared camera

    TiNi shape memory alloy (SMA) was subjected to tension at various strain rates for stress- and strain-controlled tests. The nucleation, development and saturation of the stress-induced martensitic transformation were investigated, based on the specimen temperature changes, measured by a fast and sensitive infrared camera. It was found that the initial, macroscopically homogeneous phase transformation occurs at the same stress level for all strain rates applied, regardless of the loading manner, while the stress of the localized transformation increases with the strain rate. At higher strain rate, a more dynamic course of the transformation process was observed, revealed in the creation of numerous fine transformation bands. An inflection point was noticed on the stress–strain curve, dividing the transformation range into two stages: the first heterogeneous, where transformation bands nucleate and evolve throughout the sample; the second, where the bands overlap, related to significant temperature increase and an upswing region of the curve. In the final part of the SMA loading a decrease of the average sample temperature revealed the saturation stage of the transformation. It was also observed that nucleation of the localized martensitic forward transformation takes place in the weakest area of the sample in both approaches, whereas the reverse transformation always initiates in its central part.

    Strain sensors used as flexible and wearable electronic devices have improved prospects in the fields of artificial skin, robotics, human-machine interfaces, and healthcare. This work introduces a highly stretchable fiber-based strain sensor with a laminated structure made up of a graphene nanoplatelet layer and a carbon black/single-walled carbon nanotube synergetic conductive network layer. An ultrathin, flexible, and elastic two-layer polyurethane (PU) yarn substrate was successively deposited by a novel chemical bonding-based layered dip-coating process. These strain sensors demonstrated high stretchability (˜350%), little hysteresis, and long-term durability (over 2400 cycles) due to the favorable tensile properties of the PU substrate. The linearity of the strain sensor could reach an adjusted R-squared of 0.990 at 100% strain, which is better than most of the recently reported strain sensors. Meanwhile, the strain sensor exhibited good sensibility, rapid response, and a lower detection limit. The lower detection limit benefited from the hydrogen bond-assisted laminated structure and continuous conductive path. Finally, a series of experiments were carried out based on the special features of the PU strain sensor to show its capacity of detecting and monitoring tiny human motions.

    The present study focuses on the anisotropic negative thermal expansion (NTE) behaviors of Ti-rich (Ti54Ni46) and equiatomic Ti-Ni (Ti50Ni50) alloys fabricated by vacuum arc melting and without subsequent plastic deformation. Both alloys exhibit NTE responses in vertical and horizontal directions, and the total strains and CTEs of the NTE stage along the two mutually perpendicular measuring directions are obviously different, indicating obvious anisotropic NTE behavior of the alloys. Besides, the numerical differences between the starting temperature of NTE and austenitic transformation and between the finishing temperature of NTE and austenitic transformation are very small, which indicates that an apparent relationship exists between the NTE behavior and the phase transformation. The microstructure in the vertical cross sections shows obviously preferential orientation characteristics: Ti2Ni phases of both alloys grow along the vertical direction, and B19' martensite of Ti50Ni50 alloy has distinct preferential orientation, which results from a large temperature gradient between the top and the bottom of the button ingots during solidification. The microstructure with preferential orientation induces the anisotropic NTE behavior of the samples.

    shape maximizes strength and is not a direct consequence of sapping. Infrequent flash floods of ~1-10 m3/s (woody debris and erosion indicated depth) exceed the magnitude of 1-2 L/s spring discharges by more than three orders of magnitude, and flooding is primarily responsible for sediment transport, particularly imbricated rocks up to tens of cm in size. The tributary canyons are growing headward along their contributing streams rather than up the structural dip, except where the contributing plateau surface is a dip slope (e.g., Fence and Explorer canyons). Few headwalls and contributing streams follow a large exposed tectonic joint; any structural control is primarily due to cumulative smaller fractures. These observations suggest a hybrid model for theater-headed valleys in massive rocks. Seepage weathering is an essential factor in forming steep headwalls and alcoves in Navajo sandstone, but headward retreat and erosion of debris depends on flash floods rather than seepage erosion. Plateau topography, contributing streams, and small joints rather than structural dip or large tectonic fractures control the valley planform.

    2016-02-21

    To meet some demands for realizing precise measurements of an electric dipole moment of electron (eEDM) and examining cold collisions or cold chemical physics, we have proposed a novel, versatile electrostatic Stark decelerator with an array of true 3D electric potential wells, which are created by a series of horizontally-oriented, U-shaped electrodes with time-sequence controlling high voltages (± HV) and two guiding electrodes with a constant voltage. We have calculated the 2D electric field distribution, the Stark shifts of the four lowest rotational sub-levels of PbF molecules in the X1(2)Π1/2(v = 0) electronic and vibrational ground states as well as the population in the different rotational levels. We have discussed the 2D longitudinal and transverse phase-space acceptances of PbF molecules in our decelerator. Subsequently, we have simulated the dynamic processes of the decelerated PbF molecules using the 3D Monte-Carlo method, and have found that a supersonic PbF beam with a velocity of 300 m s(-1) can be efficiently slowed to about 5 m s(-1), which will greatly enhance the sensitivities to research a parity violation and measure an eEDM. In addition, we have investigated the dependences of the longitudinal velocity spread, longitudinal temperature and bunching efficiency on both the number of guiding stages and high voltages, and found that after bunching, a cold packet of PbF molecules in the J = 7/2, MΩ = -7/4 state with a longitudinal velocity spread of 0.69 m s(-1) (corresponding to a longitudinal temperature of 2.35 mK) will be produced by our high-efficient decelerator, which will generate a high energy-resolution molecular beam for studying cold collision physics. Finally, our novel decelerator can also be used to efficiently slow NO molecules with a tiny electric dipole moment (EDM) of 0.16 D from 315 m s(-1) to 28 m s(-1). It is clear that our proposed new decelerator has a good slowing performance and experimental feasibility as well as wide

    Most critically ill injured patients are transported out of the theater by Critical Care Air Transport Teams (CCATTs). Fever after trauma is correlated with surgical complications and infection. The purposes of this study are to identify the incidence of elevated temperature in patients managed in the CCATT environment and to describe the complications reported and the treatments used in these patients. We performed a retrospective review of available records of trauma patients from the combat theater between March 1, 2009, and March 31, 2010, who were transported by the US Air Force CCATT and had an incidence of hyperthermia. We then divided the cohort into 2 groups, patients transported with an elevation in temperature greater than 100.4°F and patients with no documented elevation in temperature. We used a standardized, secure electronic data collection form to abstract the outcomes. Descriptive data collected included injury type, temperature, use of a mechanical ventilator, cooling treatment modalities, antipyretics, intravenous fluid administration, and use of blood products. We also evaluated the incidence of complications during the transport in patients who had a recorded elevation in temperature greater than 100.4°F. A total of 248 trauma patients met the inclusion criteria, and 101 trauma patients (40%) had fever. The mean age was 28 years, and 98% of patients were men. The mechanism of injury was an explosion in 156 patients (63%), blunt injury in 11 (4%), and penetrating injury in 45 (18%), whereas other trauma-related injuries accounted for 36 patients (15%). Of the patients, 209 (84%) had battle-related injuries and 39 (16%) had non-battle-related injuries. Traumatic brain injury was found in 24 patients (24%) with an incidence of elevated temperature. The mean temperature was 101.6°F (range, 100.5°F-103.9°F). After evaluation of therapies and treatments, 80 trauma patients (51%) were intubated on a mechanical ventilator (P cooling interventions

    The Afghanistan Surge saw NATO troops working with their Afghan partners to remove Taliban governance and replace it with a more democratic model. As part of this endeavor, medical support for both trauma and humanitarian cases was needed. Identify and discuss disease trends to better prepare for future combat medical treatments. Retrospective review of operative experience from a neurosurgeon from November 2010 to April 2011. 63 cases were performed on 20 NATO and 43 Afghan patients. Combat-related neurotrauma represented 73% (46/63) of cases and humanitarian cases represented the remainder. The most common diseases among humanitarian cases were benign tumors (29%, 5/17), cranioplasty (23%, 4/17), obstructive hydrocephalus (11%, 2/17), nonobstructive hydrocephalus (11%, 2/17), hemifacial spasm (11%, 2/17), and cerebral angiography (11%, 2/17). There was 1 death from ventriculitis for a complication rate of 6%. In select well-nourished, patients with minimal risk of needing tracheostomy, humanitarian neurosurgery can be safely performed in theater with a complication rate (6%) no worse than patients operated on in the United States.

    Full Text Available In the beginning of April 1917 a conflict burst out in the troupe of the Alexandrinsky Theatre: a number of prominent actors brought an accusation of aesthetic and political nature against director V.E. Meyerhold. The immediate reason for this was Meyerhold’s act – the director attended the meeting of “theatrical figures” convened by F.A. Golovin, the Commissioner of the Provisional government, not being among the persons elected to participate in the meeting of the troupe. In particular, artist R.B. Apollonsky compared V.E. Meyerhold with a famous friend of Nicholas II – G.E. Rasputin. Therefore, having ignored the accusations in “modernism”, he reacted harshly to the comparison with Rasputin. Outraged by this, Meyerhold called Apollonsky out to a duel. As a result, the duel did not take place, but the story was covered in press in unfriendly to Meyerhold light. The author concludes that Meyerhold represented in press after the February Revolution as a representative of the “old regime”, during this period was trying to distance himself from the fallen monarchy, actively assimilating the radical vocabulary. The isolation of Meyerhold in the circles of theater community took place after the described incident and was likely to make it easier for him in future to join the party of Bolsheviks.

    Airborne bacterial contamination poses a risk for surgical site infection, and routine surveillance of airborne bacteria is important. Traditional methods for detecting airborne bacteria are time consuming and strenuous. Measurement of biologic particle concentrations using a fluorescent particle counter is a novel method for evaluating air quality. The current study was to determine whether the number of biologic particles detected by the fluorescent particle counter can be used to indicate airborne bacterial counts in operating rooms. The study was performed in an operating theater at a university hospital in Hefei, China. The number of airborne biologic particles every minute was quantified using a fluorescent particle counter. Microbiologic air sampling was performed every 30 minutes using an Andersen air sampler (Pusong Electronic Instruments, Changzhou, China). Correlations between the 2 different methods were analyzed by Pearson correlation coefficients. A significant correlation was observed between biologic particle and bacterial counts (Pearson correlation coefficient = 0.76), and the counting results from 2 methods both increased substantially between operations, corresponding with human movements in the operating room. Fluorescent particle counters show potential as important tools for monitoring bacterial contamination in operating theatres.

    Applying environmental education in primate range countries is an important long-term activity to stimulate pro-conservation behavior. Within captive settings, mega-charismatic species, such as great apes are often used to increase knowledge and positively influence attitudes of visitors. Here, we evaluate the effectiveness of a short-term video and theater program developed for a Western audience and adapted to rural people living in two villages around Nouabalé-Ndoki National Park, Republic of Congo. We assessed the knowledge gain and attitude change using oral evaluation in the local language (N = 111). Overall pre-program knowledge about Western gorillas (Gorilla gorilla) was high. Detailed multivariate analysis of pre-program knowledge revealed differences in knowledge between two villages and people with different jobs while attitudes largely were similar between groups. The short-term education program was successful in raising knowledge, particularly of those people with less pre-program knowledge. We also noted an overall significant attitude improvement. Our data indicate short-term education programs are useful in quickly raising knowledge as well improving attitudes. Furthermore, education messages need to be clearly adapted to the daily livelihood realities of the audience, and multi-variate analysis can help to identify potential target groups for education programs. © 2017 Wiley Periodicals, Inc.

A concepção de politecnia, ao defender para a formação dos trabalhadores uma integração entre trabalho, ciência e cultura, abre espaço para novas possibilidades nesse campo. Autores como Paulo Freire, na educação, e Augusto Boal, no teatro, convergem para a perspectiva de construção, por parte dos trabalhadores, de uma cultura e estética próprias, que reflitam sua concepção de mundo. Buscamos pensar de que forma as proposições teatrais de Augusto Boal podem ser apropriadas para o campo da educação em saúde, tentando estabelecer afinidades e relações entre essas duas práticas, dentro da ótica de uma educação para os trabalhadores da saúde que lhes propicie uma formação humana para além daquela requerida de forma mais imediatista pelo mercado de trabalho.This article discusses the possibilities of including the performing arts in professional health education based on the aesthetic and pedagogical proposal set forth by Augusto Boal. The polytechnic concept, by advocating that workers' training include an integration of work, science and culture, opens space for new possibilities in this field. Authors such as Paulo Freire, in the field of education, and Augusto Boal, in theater, converge towards the prospect of the workers building both a culture and aesthetics of their own to reflect their world view. Our goal was to think about how Augusto Boal's theatrical propositions may be appropriate for the field of health education in an attempt to establish relationships and affinities between these two practices, from the perspective of health worker education, that they will provide the professionals with a more humanistic type of training that will extend beyond the labor market's more immediate requirements.

    Understanding the origin and evolution of Martian fluvial landforms constrains the ambiguities associated to the variability of paleoclimatic and hydrological conditions. Despite of the significance of understanding the mechanism of formation of theater-headed valleys (THV) in Valles Mariners, where abundant distribution of seasonal liquid water flow is reported, their origin remains debatable. The original groundwater sapping hypothesis is challenged by the capability of springs to cut canyons into massive rocks and alternatively mega-floods and landslides were suggested. On Earth however, widespread THV cutting through the carbonate plateaus in the Sahara are confirmed to be of long-lasting groundwater processes based on recent isotopic, geochemical and hydrogeological evidences. Geomorphological characterizations of the THV in both the Sahara and in Valles Marineris suggest similar settings including: (1) widespread and dense occurrence along the length of escarpments, (2) low relief floors, (3) association with extensive faulting, and (4) lack of well-developed stream networks and small upstream contributing areas. The above suggest that both the Martian and the Saharan THV to be of groundwater origins. Herein, we constraint the geomorphological, lithological and textural characteristics of THV in El Diffa and El-Merir plateaus in the Eastern Sahara as a limited analog to the THV in Ius Chasma using structural and textural mapping derived from ALOS PalSAR scenes and similar settings on Mars using SHARAD, MOLA and HIRISE images. These observations are correlated with several in-situ field and laboratory measurements for hardness, granulometry and channel morphology to support the common phenomenology. Preliminary findings show that in both sets of THV, we observe a spatial confinement of boulders to the sidewalls with relatively finer grains along the channel courses, and association with large-scale hydrated sulphates along the sidewalls and channel bottoms

    The Griffith Observatory, perched atop the Hollywood Hills, is perhaps the most recognizable observatory in the world. Since opening in 1935, this Los Angeles icon has brought millions of visitors closer to the heavens. Through an analysis of planning documentation, internal newsletters, media coverage, programming and exhibition design, I demonstrate how the Observatory’s Southern California location shaped its form and function. The astronomical community at nearby Mt. Wilson Observatory and Caltech informed the selection of instrumentation and programming, especially for presentations with the Observatory’s Zeiss Planetarium, the second installed in the United States. Meanwhile the Observatory staff called upon some of Hollywood’s best artists, model makers, and scriptwriters to translate the latest astronomical discoveries into spectacular audiovisual experiences, which were enhanced with Space Age technological displays on loan from Southern California’s aerospace companies. The influences of these three communities- professional astronomy, entertainment, and aerospace- persist today and continue to make Griffith Observatory one of the premiere sites of public astronomy in the country.

    In order to promote the development of Ti-Ni shape memory alloys, we have studied the correlation between the fabrication route, the chemical composition (O{sub 2} content, Zr or Hf additions), the metallurgical characteristics and the thermomechanical properties. A conventional sintering does not allow to obtain a homogeneous compound of pure Ti{sub 50}Ni{sub 50} alloy because of the occurrence of Kirkendall porosities which act as a diffusion barrier. An original process including combustion synthesis and hot-extrusion was successfully developed. Resulting products exhibit a smaller grain size (15-20{mu}m) and an enhanced workability in comparison with products obtained by arc-melting and subsequent hot rolling. The presence of oxygen in equiatomic Ti-Ni alloy induces the oxide precipitation of Ti{sub 4}Ni{sub 2}O{sub x} type (with x {<=} 1). The precipitated particle fraction is proportional to the oxygen nominal content of the alloy. We show that the decrease of the transformation temperatures is correlated with the decrease of Ti in solid solution due to Ti{sub 4}Ni{sub 2}O precipitation. Moreover, we find that a fine and homogenous oxide dispersion is suitable to decrease the grain size during hot rolling and to enhance to the one way shape memory properties. An increase of the typical transformation temperatures is obtained through of Zr or Hf (in substitution to Ti). But, an increase of the hardness is measured, and consequently the workability of the ternary alloys becomes reduced. However, it is worthwhile to point out that a Ti{sub 38}Ni{sub 50}Hf{sub 12} product obtained by arc melting and hot extrusion is able to fully recover an apparent plastic strain of more than 4% during tensile tests performed under special loading conditions. Such as behaviour is of great interest with respect to potential applications in a temperature range higher that 100 deg. C. (author). 105 refs.

    Full Text Available RESUMEN: Si la Universidad actual está demandando una educación que capacite al individuo para afrontar los cambios del futuro, hoy estamos retados a educar para el cambio. La innovación, la creatividad y el teatro como arte, son pilares fundamentales para una construcción más reveladora del conocimiento histórico educativo. Desde este planteamiento, justificamos una enseñanza de la Historia de la Educación más práctica y significativa, amparada en el uso de recursos pedagógicos más atractivos para el estudiante. Este trabajo recoge el desarrollo de una innovación docente en la asignatura Historia de la Educación Contemporánea del Grado en Pedagogía de la Universidad de Sevilla, que se concreta en la aplicación y uso de una pedagogía teatral como recurso didáctico para el conocimiento del pasado educativo. ABSTRACT: If current universities demand an education that trains individuals to face future changes, now we face the challenge to educate for change. Innovation, creativity and theater as art are fundamental pillars for a more revealing construction of historical and educational knowledge. From this approach, we can provide justification for a more practical and significant teaching of History of Education, based on the use of pedagogical resources that are more attractive for students. This paper presents the development of a teaching innovation in the History of Contemporary Education subject of the Degree Course on Pedagogy at the University of Seville, which results in the application and use of theater pedagogy as a teaching resource to learn about education in the past.

    Full Text Available A educação ambiental tem a tarefa de buscar novas formas de relacionamento entre ser humano e natureza, pautadas em um posicionamento ético, mas carrega as dificuldades impostas por um modelo de educação engessado, pautado na lógica da racionalidade técnico-científica que permeia toda a sociedade. Na tentativa de superar essa condição, propomos a educação estética ambiental como forma de o ser humano relacionar-se com o mundo que habita, tendo o desafio de provocar o reencontro do humano com as dimensões sensível, afetiva e poética que o compõem. Tendo este campo como fundamento, buscamos, teoricamente, refletir sobre a inserção de uma proposta artística como meio de se chegar aos objetivos necessários à educação ambiental. No campo da arte, voltamo-nos ao teatro do oprimido, que tem como principal objetivo a democratização do teatro, considerada atividade orgânica do ser humano. Identificamos nele aproximações com os princípios e objetivos buscados pela educação estética ambiental.The environmental education is aimed at seeking new forms of relationship between human beings and nature. Although based on an ethical position, it carries the difficulties imposed by a plaster model of education, based on the logic of technical-scientific rationality that permeates society. In an attempt to overcome such condition we propose the aesthetic environmental education as a way of human beings to relate with the world they inhabit while posing the challenge to lead the reunion with their sensitive, emotional and poetic dimensions. Having this field as a basis, we, theoretically, reflect on the inclusion of an artistic proposal as a means of achieving the necessary goals for the environmental education. In the field of art, we turn to the theater of the oppressed, which has the goal of theater democratization, as an organic activity of human beings. We have identified in it approximations to the principles and objectives

Cette salle projette à nouveau depuis juin 2010 l’attraction Captain Eo, film de science-fiction en 3D relief réalisé par Francis Ford Coppola en 1986, avec Michael Jackson dans le rôle-titre. Remplacé depuis 1998 par une autre attraction, Captain Eo fait son retour un an après le décès de la star, et implique dès lors un rapport très particulier à son public, par son statut d’hommage post-mortem.

C’est donc une approche sémio-pragmatique que nous convoquons ici, en nous référant à Roger Odin, afin d’envisager, à partir du film lui-même et de son mode de diffusion, ce que l’attraction Captain Eo révèle théoriquement du lien entre le spectateur et l’image d’une star comme Michael Jackson, qui plus est un an après son décès. Il s’agira de comprendre de quelle manière le film de Coppola ainsi que son contexte de diffusion – le parc d’attraction Disneyland Paris – permettent de penser ou d’interroger un type de pratique spectatorielle différent de celles engendrées par d'autres salles de cinéma.This article tries to question the link between the public and a precise movie theater, in Disneyland Paris Marne-La-Vallée, proposing again since june 2010 the attraction Captain Eo, science-fiction 3D movie by Francis Ford Coppola in 1986, starring Michael Jackson.

    The objective of this paper is to study the technical feasibility of a TiNi-based Shape Memory Alloy (SMA) with potential application in connections of the oil and gas Sector. The employment of this alloy would increase the reliability of these unions. Thus, a 45,0 Ti-55,0 Ni (% wt) SMA has been manufactured through the plasma skull melting and with subsequent conformation by the Push-Pull method. Samples of this SMA were heat treated at 1173 K during 900s, followed by water quenching. These samples were characterized by optic microscopy, microhardness, differential scanning calorimetry (DSC), and force generation tests. The obtained TiNi SMA has presented an important wide temperature hysteresis. The generated forces substantiate the potential application of these alloys in connection systems of the oil and gas Sector. (author)

The purpose of this study was to explore the experience of using clown theater art in the care for hospitalized children, starting with an activity developed by undergraduate students in the healthcare area. Data were obtained by observing 20 children and 11 students, characters in the clown theater interacting in the pediatric clinic in a school hospital in the state of São Paulo. The empirical data were analyzed with the thematic content analysis, which were grouped around the following themes: artistic expressions as a form of communication, participation of the binomial child and accompanying partner, and the clown as a therapeutic resource. The results show that this experience was a concrete intervention, emphasizing the children's development process, since it opens up a space for fantasy, laughter, happiness and the appropriation of the hospital routine; it is an example of widening the diagnostic and therapeutic process with the incorporation of intervention focusing on the affective, emotional and cultural necessities of the child and the family, in the search for non-traumatic care.

    ROŞCA ANGELINA

    2017-12-01

    Full Text Available The author directs her attention to an yet-understudied area of theatre science, namely the aesthetic interaction between the provocative performance and the provocative theatre. The article sheds light on the conceptual coordinates of the performance placed among such artistic trends as Actionism, Conceptualism, Fluxus and Happening. Elements of performing arts infiltrated into the theatre long ago. And it is not just a co-occurrence within an artistic act, but an interference indeed. The provocative performance dispossesses the alternative arts of their distinct codes. First in the USA, then in Europe and eventually in the former Socialist Camp and the territory of the ex-USSR, the performance conquered the theatrical territory. This process has been accelerating since the dramatic theatre began to yield its positions to the post-dramatic one. Some of the overlapping points, which unite the performance with the spectacle in contemporary art, are followed in: the strategy of idiocy in provocative practices; the ready made; the corporeality; the pictorial.

    A prototype system for tracking tactical ballistic missiles using multiple radars has been developed. The tracking is based on measurement level fusion (`true' multi-radar) tracking. Strobes from passive sensors can also be used. We describe various features of the system with some emphasis on the filtering technique. This is based on the Interacting Multiple Model framework where the states are Free Flight, Drag, Boost, and Auxiliary. Measurement error modeling includes the signal to noise ratio dependence; outliers and miscorrelations are handled in the same way. The launch point is calculated within one minute from the detection of the missile. The impact point, and its uncertainty region, is calculated continually by extrapolating the track state vector using the equations of planetary motion.

    2007-06-01

    Over a decade ago, I introduced a large-scale theory of the cognitive brain which explained for the first time how the human brain is able to create internal models of its intimate world and invent models of a wider universe. An essential part of the theoretical model is an organization of neuronal mechanisms which I have named the Retinoid Model [Trehub, A. (1977). Neuronal models for cognitive processes: Networks for learning, perception and imagination. Journal of Theoretical Biology, 65, 141-169; Trehub, A. (1991). The Cognitive Brain: MIT Press]. This hypothesized brain system has structural and dynamic properties enabling it to register and appropriately integrate disparate foveal stimuli into a perspectival, egocentric representation of an extended 3D world scene including a neuronally tokened locus of the self which, in this theory, is the neuronal origin of retinoid space. As an integral part of the larger neuro-cognitive model, the retinoid system is able to perform many other useful perceptual and higher cognitive functions. In this paper, I draw on the hypothesized properties of this system to argue that neuronal activity within the retinoid structure constitutes the phenomenal content of consciousness and the unique sense of self that each of us experiences.

    A new nasal drug delivery system of diazepam has been developed with a natural mucoadhesive agent from Tamarindus indica L. The mucoadhesive strength, viscosity and gelling property of this natural mucoadhesive agent was found to be higher in comparison to synthetic polymers, hydroxyl propyl methyl cellulose (HPMC) and carbopol 934 which are conventionally used for similar purpose. In vitro drug release characteristic through franz-diffusion cell using excised bovine nasal membrane was also found to be better in comparison to the above synthetic polymers. This patient friendly, needle free dosage form may replace the diazepam injections in future. (author)

    Security becomes a very important issue in data transmission and there are so many methods to make files more secure. One of that method is cryptography. Cryptography is a method to secure file by writing the hidden code to cover the original file. Therefore, if the people do not involve in cryptography, they cannot decrypt the hidden code to read the original file. There are many methods are used in cryptography, one of that method is hybrid cryptosystem. A hybrid cryptosystem is a method that uses a symmetric algorithm to secure the file and use an asymmetric algorithm to secure the symmetric algorithm key. In this research, TEA algorithm is used as symmetric algorithm and LUC algorithm is used as an asymmetric algorithm. The system is tested by encrypting and decrypting the file by using TEA algorithm and using LUC algorithm to encrypt and decrypt the TEA key. The result of this research is by using TEA Algorithm to encrypt the file, the cipher text form is the character from ASCII (American Standard for Information Interchange) table in the form of hexadecimal numbers and the cipher text size increase by sixteen bytes as the plaintext length is increased by eight characters.

  11. Stable isotope deltas: Tiny, yet robust signatures in nature

    Science.gov (United States)

    Brand, Willi A.; Coplen, Tyler B.

    2012-01-01

    Although most of them are relatively small, stable isotope deltas of naturally occurring substances are robust and enable workers in anthropology, atmospheric sciences, biology, chemistry, environmental sciences, food and drug authentication, forensic science, geochemistry, geology, oceanography, and paleoclimatology to study a variety of topics. Two fundamental processes explain the stable isotope deltas measured in most terrestrial systems: isotopic fractionation and isotope mixing. Isotopic fractionation is the result of equilibrium or kinetic physicochemical processes that fractionate isotopes because of small differences in physical or chemical properties of molecular species having different isotopes. It is shown that the mixing of radioactive and stable isotope end members can be modelled to provide information on many natural processes, including 14C abundances in the modern atmosphere and the stable hydrogen and oxygen isotopic compositions of the oceans during glacial and interglacial times. The calculation of mixing fractions using isotope balance equations with isotope deltas can be substantially in error when substances with high concentrations of heavy isotopes (e.g. 13C, 2H, and 18O ) are mixed. In such cases, calculations using mole fractions are preferred as they produce accurate mixing fractions. Isotope deltas are dimensionless quantities. In the International System of Units (SI), these quantities have the unit 1 and the usual list of prefixes is not applicable. To overcome traditional limitations with expressing orders of magnitude differences in isotope deltas, we propose the term urey (symbol Ur), after Harold C. Urey, for the unit 1. In such a manner, an isotope delta value expressed traditionally as−25 per mil can be written as−25 mUr (or−2.5 cUr or−0.25 dUr; the use of any SI prefix is possible). Likewise, very small isotopic differences often expressed in per meg ‘units’ are easily included (e.g. either+0.015 ‰ or+15 per meg can be written as+15 μUr.

  12. Tiny Moments Matter: Promoting Professionalism in Everyday Practice.

    2018-01-01

    Professionalism rests upon a number of individual, environmental, and societal level factors, leading to specific professional behavior in specific situations. Focusing on professional lapses to identify and remediate unprofessional physicians is incomplete. We explored professionalism in practicing internal medicine physicians in the context of everyday practice, to highlight how typical experiences contribute to positive, yet often unnoticed, professional behavior. In-depth interviews were used to uncover 13 physicians' most meaningful experiences of professionalism. Data were collected and analyzed using a grounded theory approach. Results revealed several themes around which physicians embody professionalism in their daily lives. Physicians feel most professional when they are able to connect and establish trust with patients and colleagues and when they serve as positive role models to others. Physicians conceptualize professionalism as a dynamic and evolving competency, one that requires a lifelong commitment and that provides opportunities for lifelong learning. Focusing on actual perceptions of experiences in practice offers important insights into how physicians think about professionalism beyond a traditional remediation and lapses perspective. Physicians often go out of their way to connect with patients and colleagues, serving and modeling for others, often at the expense of their own work-life balance. These moments help to infuse energy and positivity into physician practices during a time when physicians may feel overburdened, overscheduled, and overregulated. Understanding professionalism as developmental helps frame professionalism as a lifelong competency subject to growth and modification over time.

  13. Tiny bubbles challenge giant turbines: Three Gorges puzzle.

    Li, Shengcai

    2015-10-06

    Since the birth of the first prototype of the modern reaction turbine, cavitation as conjectured by Euler in 1754 always presents as a challenge. Following his theory, the evolution of modern reaction (Francis and Kaplan) turbines has been completed by adding the final piece of the element 'draft-tube' that enables turbines to explore water energy at efficiencies of almost 100%. However, during the last two and a half centuries, with increasing unit capacity and specific speed, the problem of cavitation has been manifested and complicated by the draft-tube surges rather than being solved. Particularly, during the last 20 years, the fierce competition in the international market for extremely large turbines with compact design has encouraged the development of giant Francis turbines of 700-1000 MW. The first group (24 units) of such giant turbines of 700 MW each was installed in the Three Gorges project. Immediately after commission, a strange erosion phenomenon appeared on the guide vane of the machines that has puzzled professionals. From a multi-disciplinary analysis, this Three Gorges puzzle could reflect an unknown type of cavitation inception presumably triggered by turbulence production from the boundary-layer streak transitional process. It thus presents a fresh challenge not only to this old turbine industry, but also to the fundamental sciences.

  15. Nanotechnology: the revolution of the big future with tiny medicine.

    Science.gov (United States)

    Meetoo, Danny

    The historically unprecedented developments of nanoscience and nanotechnology (NT) promise to revolutionize the diagnosis, treatment and prevention of disease and traumatic injury, to relieve pain, and to preserve and improve human health, using molecular tools and molecular knowledge of the body. This article focuses on what is known as nanomedicine, referring to a definition of NT, its historical overview and developments as well as its application to medicine. In revolutionizing the manufacturing process to a nanoscale, NT promises to resolve the problems currently faced by the human race. However, in embracing this panacea, its implications, particularly within health care, cannot be ignored. This article, therefore, provides a thought-provoking consideration of how NT is likely to impact on nursing, together with the issues likely to be encountered during the care delivery process. Finally, some of the ethical questions nurses need to debate has been raised.

  16. MEASURING TINY MASS ACCRETION RATES ONTO YOUNG BROWN DWARFS

    International Nuclear Information System (INIS)

    Herczeg, Gregory J.; Cruz, Kelle L.; Hillenbrand, Lynne A.

    2009-01-01

    We present low-resolution Keck I/LRIS spectra spanning from 3200 to 9000 A of nine young brown dwarfs and three low-mass stars in the TW Hya Association and in Upper Sco. The optical spectral types of the brown dwarfs range from M5.5 to M8.75, though two have near-IR spectral types of early L dwarfs. We report new accretion rates derived from excess Balmer continuum emission for the low-mass stars TW Hya and Hen 3-600A and the brown dwarfs 2MASS J12073347-3932540, UScoCTIO 128, SSSPM J1102-3431, USco J160606.29-233513.3, DENIS-P J160603.9-205644, and Oph J162225-240515B, and upper limits on accretion for the low-mass star Hen 3-600B and the brown dwarfs UScoCTIO 112, Oph J162225-240515A, and USco J160723.82-221102.0. For the six brown dwarfs in our sample that are faintest at short wavelengths, the accretion luminosity or upper limit is measurable only when the image is binned over large wavelength intervals. This method extends our sensitivity to accretion rate down to ∼10 -13 M sun yr -1 for brown dwarfs. Since the ability to measure an accretion rate from excess Balmer continuum emission depends on the contrast between excess continuum emission and the underlying photosphere, for objects with earlier spectral types the upper limit on accretion rate is much higher. Absolute uncertainties in our accretion rate measurements of ∼3-5 include uncertainty in accretion models, brown dwarf masses, and distance. The accretion rate of 2 x 10 -12 M sun yr -1 onto 2MASS J12073347-3932540 is within 15% of two previous measurements, despite large changes in the Hα flux.

  17. The Milky Way's Tiny but Tough Galactic Neighbour

    Science.gov (United States)

    2009-10-01

    Today ESO announces the release of a stunning new image of one of our nearest galactic neighbours, Barnard's Galaxy, also known as NGC 6822. The galaxy contains regions of rich star formation and curious nebulae, such as the bubble clearly visible in the upper left of this remarkable vista. Astronomers classify NGC 6822 as an irregular dwarf galaxy because of its odd shape and relatively diminutive size by galactic standards. The strange shapes of these cosmic misfits help researchers understand how galaxies interact, evolve and occasionally "cannibalise" each other, leaving behind radiant, star-filled scraps. In the new ESO image, Barnard's Galaxy glows beneath a sea of foreground stars in the direction of the constellation of Sagittarius (the Archer). At the relatively close distance of about 1.6 million light-years, Barnard's Galaxy is a member of the Local Group, the archipelago of galaxies that includes our home, the Milky Way. The nickname of NGC 6822 comes from its discoverer, the American astronomer Edward Emerson Barnard, who first spied this visually elusive cosmic islet using a 125-millimetre aperture refractor in 1884. Astronomers obtained this latest portrait using the Wide Field Imager (WFI) attached to the 2.2-metre MPG/ESO telescope at ESO's La Silla Observatory in northern Chile. Even though Barnard's Galaxy lacks the majestic spiral arms and glowing, central bulge that grace its big galactic neighbours, the Milky Way, the Andromeda and the Triangulum galaxies, this dwarf galaxy has no shortage of stellar splendour and pyrotechnics. Reddish nebulae in this image reveal regions of active star formation, where young, hot stars heat up nearby gas clouds. Also prominent in the upper left of this new image is a striking bubble-shaped nebula. At the nebula's centre, a clutch of massive, scorching stars send waves of matter smashing into the surrounding interstellar material, generating a glowing structure that appears ring-like from our perspective. Other similar ripples of heated matter thrown out by feisty young stars are dotted across Barnard's Galaxy. At only about a tenth of the Milky Way's size, Barnard's Galaxy fits its dwarfish classification. All told, it contains about 10 million stars - a far cry from the Milky Way's estimated 400 billion. In the Local Group, as elsewhere in the Universe, however, dwarf galaxies outnumber their larger, shapelier cousins. Irregular dwarf galaxies like Barnard's Galaxy get their random, blob-like forms from close encounters with or "digestion" by other galaxies. Like everything else in the Universe, galaxies are in motion, and they often make close passes or even go through one another. The density of stars in galaxies is quite low, meaning that few stars physically collide during these cosmic dust-ups. Gravity's fatal attraction, however, can dramatically warp and scramble the shapes of the passing or crashing galaxies. Whole bunches of stars are pulled or flung from their galactic home, in turn forming irregularly shaped dwarf galaxies like NGC 6822. More information ESO, the European Southern Observatory, is the foremost intergovernmental astronomy organisation in Europe and the world's most productive astronomical observatory. It is supported by 14 countries: Austria, Belgium, the Czech Republic, Denmark, France, Finland, Germany, Italy, the Netherlands, Portugal, Spain, Sweden, Switzerland and the United Kingdom. ESO carries out an ambitious programme focused on the design, construction and operation of powerful ground-based observing facilities enabling astronomers to make important scientific discoveries. ESO also plays a leading role in promoting and organising cooperation in astronomical research. ESO operates three unique world-class observing sites in Chile: La Silla, Paranal and Chajnantor. At Paranal, ESO operates the Very Large Telescope, the world's most advanced visible-light astronomical observatory. ESO is the European partner of a revolutionary astronomical telescope ALMA, the largest astronomical project in existence. ESO is currently planning a 42-metre European Extremely Large optical/near-infrared Telescope, the E-ELT, which will become "the world's biggest eye on the sky".

  1. Phosphoinositides: Tiny Lipids With Giant Impact on Cell Regulation

    Science.gov (United States)

    2013-01-01

    Phosphoinositides (PIs) make up only a small fraction of cellular phospholipids, yet they control almost all aspects of a cell's life and death. These lipids gained tremendous research interest as plasma membrane signaling molecules when discovered in the 1970s and 1980s. Research in the last 15 years has added a wide range of biological processes regulated by PIs, turning these lipids into one of the most universal signaling entities in eukaryotic cells. PIs control organelle biology by regulating vesicular trafficking, but they also modulate lipid distribution and metabolism via their close relationship with lipid transfer proteins. PIs regulate ion channels, pumps, and transporters and control both endocytic and exocytic processes. The nuclear phosphoinositides have grown from being an epiphenomenon to a research area of its own. As expected from such pleiotropic regulators, derangements of phosphoinositide metabolism are responsible for a number of human diseases ranging from rare genetic disorders to the most common ones such as cancer, obesity, and diabetes. Moreover, it is increasingly evident that a number of infectious agents hijack the PI regulatory systems of host cells for their intracellular movements, replication, and assembly. As a result, PI converting enzymes began to be noticed by pharmaceutical companies as potential therapeutic targets. This review is an attempt to give an overview of this enormous research field focusing on major developments in diverse areas of basic science linked to cellular physiology and disease.

    Nanomedicine is an emerging field that integrates nanotechnology, biomolecular engineering, life sciences and medicine; it is expected to produce major breakthroughs in medical diagnostics and therapeutics. Nano-scale structures and devices are compatible in size with proteins and nucleic acids in living cells. Therefore, the design, characterization and application of nano-scale probes, carriers and machines may provide unprecedented opportunities for achieving a better control of biological processes, and drastic improvements in disease detection, therapy, and prevention. Recent advances in nanomedicine include the development of nanoparticle (NP)-based probes for molecular imaging, nano-carriers for drug/gene delivery, multifunctional NPs for theranostics, and molecular machines for biological and medical studies. This article provides an overview of the nanomedicine field, with an emphasis on NPs for imaging and therapy, as well as engineered nucleases for genome editing. The challenges in translating nanomedicine approaches to clinical applications are discussed.

  5. Strain Recovery by TiNi Element Under Fast Heating

    2018-01-01

    A theoretical and experimental study of strain recovery under fast heating of a shape memory alloy (SMA) rod preliminarily stretched in the martensitic state is carried out. Two theoretical models are considered: instantaneous heating and heating with temperature variation during a finite time. In the first case, it is supposed that the straight SMA rod experiences an instantaneous reverse martensitic transformation, and in the second the transformation is supposed to progress at a rate corresponding to the temperature rate. Analytical expression for the time dependence of the rod free-end displacement is obtained. In the experiment, a wire specimen made of titanium-nickel SMA was heated by a short impulse of electric current. The variation of the specimen length in time was registered. Thus, it has been shown that the minimum operation time of an SMA actuator (time needed for the strain recovery) can be reduced to 20 µs. Comparison of the theoretical results with the experimental ones leads to the conclusion that the displacement variation in time is controlled by the rate of heating and the inertia of the specimen. The incubation time of the martensitic transformation on the microscale apparently is estimated as less than 1 µs.

    The most significant advances in Earth, solar, and space physics over the next decades will originate from new, system-level observational techniques. The most promising technique to still be fully developed and exploited requires conducting multi-point or distributed constellation-based observations. This system-level observational approach is required to understand the 'big picture' coupling between disparate regions such as the solar-wind, magnetosphere, ionosphere, upper atmosphere, land, and ocean. The national research council, NASA science mission directorate, and the larger heliophysics community have repeatedly identified the pressing need for multipoint scientific investigations to be implemented via satellite constellations. The NASA Solar Terrestrial Probes Magnetospheric Multiscale (MMS) mission and NASA Earth Science Division's 'A-train', consisting of the AQUA, CloudSat, CALIPSO and AURA satellites, are examples of such constellations. However, the costs to date of these and other similar proposed constellations have been prohibitive given the 'large satellite' architectures and the multiple launch vehicles required for implementing the constellations. Financially sustainable development and deployment of multi-spacecraft constellations can only be achieved through the use of small spacecraft that allow for multiple hostings per launch vehicle. The revolution in commercial mobile and other battery powered consumer technology has helped enable researchers in recent years to build and fly very small yet capable satellites, principally CubeSats. A majority of the CubeSat activity and development to date has come from international academia and the amateur radio satellite community, but several of the typical large-satellite vendors have developed CubeSats as well. Recent government-sponsored CubeSat initiatives, such as the NRO Colony, NSF CubeSat Space Weather, NASA Office of Chief Technologist Edison and CubeSat Launch Initiative (CSLI) Educational Launch of Nanosatellites Educational Launch of Nano-satellites (ELaNa), the Air Force Space Environmental NanoSat Experiment (SENSE), and the ESA QB50 programs have spurred the development of very proficient miniature space sensors and technologies that enable technology demonstration, space and earth science research, and operational CubeSat based missions. In this paper we will review many of the small, low cost sensor and instrumentation technologies that have been developed to date as part of the CubeSat movement and examine how these new CubeSat based technologies are helping us do more with less.

    Full Text Available A new move of renovation started with the foundation of the Republic of Turkey after the country was freed from enemy invasion. At that time it was the Western nations who made up the modern worldand owned the cutting edge science and technology. Consequently thenew Turkish republic looked to the Western civilization whichrepresented "the modern". Renovation involved not only the fields ofscience and technology which were deemed as the catalysts ofmodernization but also cultural issues. In the aftermath of thefoundation of the republic modernization was directed toward culturalissues. Various cultural activities were organized in order to make thepublic adopt the new regime through and increase public interest in art.Among these cultural activities production and staging on theaters ofnew plays are remarkable.The aim in this study is to examine the works of theater producedafter the proclamation of the Republic, between 1923-1938 from thepoint of view of Kemalism. In this paper, those theater works whichwere produced between 1923 and 1938 (the year when M.KemalAtatürk passed away are examined.

    Full Text Available Xyloglucans (XGs of Tamarindus indica L. Fabaceae are used as drug vehicles or as ingredients of cosmetics. Two xyloglucans were extracted from T. indica seed with cold water (TSw and copper complex precipitation (TSc. Both were analyzed in regard to composition and influence on cell viability, proliferation, cell cycle progression, migration, MAPK phosphorylation, and gene expression of human skin keratinocytes (NHEK and HaCaT and fibroblasts (NHDF in vitro. TSw and TSc differed in molecular weight, rhamnose content, and ratios of xylose, arabinose, galactose, and glucose. Both XGs improved keratinocytes and fibroblast proliferation, promoted the cell cycle, and stimulated migration and intracellular enzyme activity of NHDF after endosomal uptake. Only TSw significantly enhanced HaCaT migration and extracellular enzyme activity of NHDF and HaCaT. TSw and TSc predominantly enhanced the phosphorylation of molecules that referred to Erk signaling in NHEK. In NHDF parts of the integrin signaling and SAPK/JNK pathway were affected. Independent of cell type TSw marginally regulated the expression of genes, which referred to membrane proteins, cytoskeleton, cytokine signaling, and ECM as well as to processes of metabolism and transcription. Results show that T. indica xyloglucans promote skin regeneration by a direct influence on cell proliferation and migration.

    Maranhão (Southeastern Brazil, 2009. A structured questionnaire was used, which was administered before and after the intervention. The pedagogical device was the "Theater of the Oppressed". The dependent variables were specific and global knowledge about clinical research and about parasitic worms; the independent variable was participation in the educational intervention. RESULTS: There was an increase in knowledge about signals and symptoms, susceptibility to reinfection and way of contagion after the educational intervention. We observed an increase in the number of right answers concerning duration of clinical research, procedures, the possibility of quitting participation, and occurrence of adverse events. The notion that the research's primary purpose is therapeutic remained, but the percentage of participants who associated the research with medical treatment decreased. The "Theater of the Oppressed" enabled that the discussions about helminthiasis and clinical research were contextualized and materialized. The subjects could dispose of or reduce their previous representations. CONCLUSIONS: Participation of children and adolescents in clinical trials must be preceded by an educational intervention, since individuals of that age group do not even recognize they have the right to decide for themselves.

    This paper reports that in what should be a reassuring phenomenon for America's European allies, US military planners think of applications of new technologies in new conventional weapons systems almost exclusively in the context of defending Western Europe. Given the global interests of the United States and the nature and location of emerging threats (as the Gulf war has so dramatically emphasized) this is a rather narrow base for US conventional weapons modernization planning. As recent events in Eastern Europe make clear, the cogency of America's defense policy may be dramatically undermined by the reduction of the Soviet threat. As yet, it is unclear to what extent the development of future conventional forces will be conducted with reference to America's participation in NATO

    Full Text Available This essay uses the concept of the constellation to characterize the relations among interdisciplinarity, cultural memory, and comparative literature. To do so entails: (a reviewing the paradoxical interdisciplinarity of comparative literature, (b tracing its establishment at a liberal arts college (Bryn Mawr College, USA, and (c describing a course on “The Cultural Politics of Memory” that tested the limits of scholarship and testimony. The discussion includes an account of an unusual conference on cultural memory: that is, the ways in which different cultural groups identify and describe their shared pasts. The informality and collegial dialogue of the conference were associated with a liberal arts context. It then turns to the question of theorizing aspects of cultural memory that are conveyed at the margins of conventional discourse: by what is largely unsaid, or represented in dance or pantomime. Because each of the performances discussed here is related in a distinct way to a preceding historical trauma (the Khmer Rouge regime in Cambodia, African American slavery in the USA, the terrorism of the Shining Path in Peru, it was important to determine what source of memory, what archival materials, could persist through traumas that often suppress memory. Traditional archives consist of written documents. Moreover, they often support or represent official histories. New ways of thinking about archives--their composition, their place in cultural history, and their theoretical dimensions--have suggested new approaches to cultural memory. The essay ends with accounts of three forms of dance or pantomime that convey cultural histories informed by trauma in significantly different ways. A narrative thread foregrounds the close relations between scholarship and pedagogy.

    Full Text Available Nelle sue pièces comiche il drammaturgo franco-argentino Copi (1939-1987 si confronta con la tragedia, immergendo riferimenti e forme tragiche nell’umorismo e nel camp, all’interno di una cornice caratterizzata dal relativismo più estremo, in cui vita e morte coincidono e in cui ogni personaggio (spesso transgender afferma e nega la propria identità. Gli ‘eroi’ di Copi mostrano un difetto di volontà, che porta i loro sforzi titanici a diventare perdenti e a infrangersi contro risultati ridicoli o contro lo stallo. Le pièces oscillano tra «circo» e «tragedia», come dice il protagonista di Cachafaz (1981, definita dall’autore «tragedia barbara», in cui la tradizione del gauchesco argentino si coniuga con una visione cruenta e soprannaturale della tragedia, tra Macbeth e Le baccanti. Il linguaggio della commedia umoristica e camp è la base per la ricostruzione di un nuovo linguaggio tragico, e l’intero corpus teatrale di Copi non si presenta come parodia o dissacrazione, bensì come ‘riattivazione’ della tragedia nel secolo della sua ‘morte’ (Steiner.

  2. Simulation-based planning for theater air warfare

    Science.gov (United States)

    Popken, Douglas A.; Cox, Louis A., Jr.

    2004-08-01

    Planning for Theatre Air Warfare can be represented as a hierarchy of decisions. At the top level, surviving airframes must be assigned to roles (e.g., Air Defense, Counter Air, Close Air Support, and AAF Suppression) in each time period in response to changing enemy air defense capabilities, remaining targets, and roles of opposing aircraft. At the middle level, aircraft are allocated to specific targets to support their assigned roles. At the lowest level, routing and engagement decisions are made for individual missions. The decisions at each level form a set of time-sequenced Courses of Action taken by opposing forces. This paper introduces a set of simulation-based optimization heuristics operating within this planning hierarchy to optimize allocations of aircraft. The algorithms estimate distributions for stochastic outcomes of the pairs of Red/Blue decisions. Rather than using traditional stochastic dynamic programming to determine optimal strategies, we use an innovative combination of heuristics, simulation-optimization, and mathematical programming. Blue decisions are guided by a stochastic hill-climbing search algorithm while Red decisions are found by optimizing over a continuous representation of the decision space. Stochastic outcomes are then provided by fast, Lanchester-type attrition simulations. This paper summarizes preliminary results from top and middle level models.

    Full Text Available The substance of the spiritual and cultural life is the syncretism of the arts from the performer-spectator division, that was made concurrently with the “dance” segmentation into work and pleasure. Words were held in formulas, gestures and dance in rhythm. Today, dance is mostly seen as the art of gesture. However, it is remarkable to reflect at to what extent the dance, as an organic necessity, it could further develop into hermetic structures that would still require analyses and studies from researchers in the field. In today‟s theatrical landscape, this formula of artistic expression which was called theatre dance evolved so much so that gesticulations and body exploration became its core components.

    Science.gov (United States)

    Marzo, Asier; Barnes, Adrian; Drinkwater, Bruce W.

    2017-08-01

    Acoustic levitation has the potential to enable novel studies due to its ability to hold a wide variety of substances against gravity under container-less conditions. It has found application in spectroscopy, chemistry, and the study of organisms in microgravity. Current levitators are constructed using Langevin horns that need to be manufactured to high tolerance with carefully matched resonant frequencies. This resonance condition is hard to maintain as their temperature changes due to transduction heating. In addition, Langevin horns are required to operate at high voltages (>100 V) which may cause problems in challenging experimental environments. Here, we design, build, and evaluate a single-axis levitator based on multiple, low-voltage (ca. 20 V), well-matched, and commercially available ultrasonic transducers. The levitator operates at 40 kHz in air and can trap objects above 2.2 g/cm3 density and 4 mm in diameter whilst consuming 10 W of input power. Levitation of water, fused-silica spheres, small insects, and electronic components is demonstrated. The device is constructed from low-cost off-the-shelf components and is easily assembled using 3D printed sections. Complete instructions and a part list are provided on how to assemble the levitator.

    Waldo, N.; Neumann, R. B.

    2017-12-01

    When most people think about global climate change they think about massive power plants billowing smoke and expansive glaciers melting to nothingness. What the public often overlooks is how natural processes invisible to the naked eye can be changed by the climate, and the fact that the natural response to those changes can further alter the climate. Scientists call these reactions "feedback cycles", and understanding them is crucial to predicting the true impact of human activities. In our research, we study one particular feedback cycle: the effect of increased plant productivity on methane emissions from wetlands. Globally, wetlands account for about a third of annual emissions of methane, the second most important greenhouse gas after carbon dioxide. This heat-trapping gas is generated in the soil of wetlands by microscopic organisms that consume, among other things, proteins and sugars released by the roots of plants. As the atmosphere becomes warmer and richer in carbon dioxide, these plants will grow larger and faster, releasing more of this microbe food into the soil. Our current research seeks to understand how that will affect the microbial ecosystem, and through it the emissions of methane gas.

    The Solar Photometer in X-rays (SphinX) was designed to observe soft X-ray solar emission in the energy range between ~1 keV and 15 keV with the resolution better than 0.5 keV. The instrument operated from February until November 2009 aboard CORONAS-Photon satellite, during the phase of exceptionally low minimum of solar activity. Here we use SphinX data for analysis of micro-flares and brightenings. Despite a very low activity more than a thousand small X-ray events have been recognized by semi-automatic inspection of SphinX light curves. A catalogue of temporal and physical characteristics of these events is shown and discussed and results of the statistical analysis of the catalogue data are presented.

    Diabetic cardiomyopathy (DCM) is described as impaired cardiac diastolic and systolic functions. Diabetes mellitus (DM), a related cardiovascular disease, has become one of the major causes of death in DM patients. Mortality in these diseases is 2 to 3 times higher than in non-DM patients with cardiovascular disease. The progression of DCM and the cellular and molecular perturbations associated with the pathogenesis are complex and multifactorial. Although considerable progress has been achieved, the molecular etiologies of DCM remain poorly understood. There is an expanding need for natural antidiabetic medicines that do not cause the side effects of modern drugs. Curcumin, a pleiotropic molecule, from Curcuma longa, is known to possess numerous impacts such as scavenging free radical, antioxidant, antitumor, and antiinflammatory activities. The reports from preclinical and clinical findings revealed that curcumin can reverse insulin resistance, hyperglycemia, obesity, and obesity-related metabolic diseases. The current review provides an updated overview of the possible molecular mechanism of DCM and multitarget approach of curcumin in alleviating DCM and diabetic complication. Additionally, we mentioned the approaches that are currently being implemented to improve the bioavailability of this promising natural product in diabetes therapeutics.

    Yonath, Ada

    An impressive number of crystal structures of ribosomes, the universal cellular machines that translate the genetic code into proteins, emerged during the last decade. The determination of ribosome high resolution structure, which was widely considered formidable, led to novel insights into the ribosomal function, namely, fidelity, catalytic mechanism, and polymerize activities. They also led to suggestions concerning its origin and shed light on the action, selectivity and synergism of ribosomal antibiotics; illuminated mechanisms acquiring bacterial resistance and provided structural information for drug improvement and design. These studies required the pioneering and implementation of advanced technologies, which directly influenced the remarkable increase of the number of structures deposited in the Protein Data Bank.

    Full Text Available The cognitive mechanisms underpinning the well-established relationship between inhibitory control and early maths skills remain unclear. We hypothesised that a specific aspect of inhibitory control drives its association with distinct math skills in very young children: the ability to ignore stimulus dimensions that are in conflict with task-relevant representations. We used an Animal Size Stroop task in which three- to six-year-olds were required to ignore the physical size of animal pictures to compare their real-life dimensions. In Experiment 1 (N=58, performance on this task correlated with standardised early mathematics achievement. In Experiment 2 (N=48, performance on the Animal Size Stroop task related to the accuracy of magnitude comparison, specifically for trials on which the physical size of dot arrays was incongruent with their numerosity. This highlights a process-oriented relationship between interference control and resolving conflict between discrete and continuous quantity, and in turn calls for further detailed empirical investigations of whether, how and why inhibitory processes matter to emerging numerical cognition.

    The self-consistent calculation of NiTi B2 and B19' phases have been performed by the linear muffin-tin orbital method in atomic sphere approximation (LMTO-ASA). Two approaches for calculation of B2-phase band structure have been used and the essential differences in the Fermi surface have been pointed out. The alterations of NiTi electron characteristics at the martensitic transition have been analyzed. The optical spectra and their peculiarities in B2 and monoclinic B19' phases have been discussed. In the frames of first principles method electron-positron annihilation characteristics in B2-NiTi have been investigated too. It was shown that a rather satisfactory agreement with experimental results for NiTi was achieved. (orig.)

    There is ample evidence that tube-dwelling invertebrates such as chironomids significantly alter multiple important ecosystem functions, particularly in shallow lakes. Chironomids pump large water volumes, and associated suspended and dissolved substances, through the sediment and thereby compete

  15. Tiny Tremors to Titanic Explosions: Tackling Transients in Anomalous X-Ray Pulsars (core Program)

    Science.gov (United States)

    We are requesting the target-of-oppurtunity (ToO) component of an ongoing, successful, long-term RXTE monitoring campaign of anomalous X- ray pulsars (AXPs). Their nature had been a mystery, but with our discoveries of X-ray bursts from AXPs, there is compelling evidence that they are young, isolated, ultra-magnetized neutron stars or "magnetars." We request ToO observations of any of the known and candidate AXPs as well as of any newly discovered AXPs should they exhibit anomalous behavior of one or more of the following types: bursts, significant sudden pulse profile changes, glitches or other rotational anomalies, or pulse fractions changes. These observations will allow us to answer basic physical questions about neutron star structure.

    The past decade has seen major progress in neutron star astrophysics, with the discovery of magnetars in general, and the recognition that the Anomalous X-ray Pulsars (AXPs) fall in this class. AXPs have recently revealed surprising and dramatic variability behavior, which theorists have begun to show are highly constraining of physical models of magnetars, including their crusts, atmospheres, coronae and magnetospheres. In this proposal, we request Chandra/ACIS-S Target-of-Opportunity observations of one major Anomalous X-ray Pulsar (AXP) outburst in AO13, in order to study in detail the evolution of the spectrum, pulsed fraction and pulse profile, for quantitative confrontation with recently developed models for the structure and electrodynamics of magnetars.

    While studying actin assembly as a graduate student with Matt Welch at the University of California at Berkeley, my interest was piqued by reports of surprising observations in bacteria: the identification of numerous cytoskeletal proteins, actin homologues fulfilling spindle-like functions, and even the presence of membrane-bound organelles. Curiosity about these phenomena drew me to Lucy Shapiro's lab at Stanford University for my postdoctoral research. In the Shapiro lab, and now in my lab at Johns Hopkins, I have focused on investigating the mechanisms of bacterial cytokinesis. Spending time as both a eukaryotic cell biologist and a bacterial cell biologist has convinced me that bacterial cells present the same questions as eukaryotic cells: How are chromosomes organized and accurately segregated? How is force generated for cytokinesis? How is polarity established? How are signals transduced within and between cells? These problems are conceptually similar between eukaryotes and bacteria, although their solutions can differ significantly in specifics. In this Perspective, I provide a broad view of cell biological phenomena in bacteria, the technical challenges facing those of us who peer into bacterial cells, and areas of common ground as research in eukaryotic and bacterial cell biology moves forward.
