    1980-04-01

    The solar energy hot water system installed in the Quality Inn, Key West, Florida, which consists of four buildings is described. Three buildings are low-rise, two-story buildings containing 100 rooms. The fourth is a four-story building with 48 rooms. The solar system was designed to provide approximately 50 percent of the energy required for the domestic hot water system. The solar system consists of approximately 1400 square feet of flat plate collector, two 500 gallon storage tanks, a circulating pump, and a controller. Operation of the system was begun in April 1978, and has continued to date with only three minor interruptions for pump repair. In the first year of operation, it was determined that the use of the solar facility resulted in forty percent fuel savings.

  9. Holiday thrombosis.

    Lippi, Giuseppe; Franchini, Massimo; Favaloro, Emmanuel J

    2011-11-01

    The pathogenesis of acute thrombosis, either arterial or venous, is typically multifactorial and involves a variety of factors that may be considered relatively "innocuous" when present alone. When someone is unlucky enough to accumulate several risk factors, compounded in many cases by one or more acute triggers, that person may be propelled over a threshold that precipitates the development of an acute episode of thrombosis. There is now reliable evidence that acute thromboses (both venous thromboembolism and acute coronary syndrome) follow a typical seasonal pattern and particularly display a characteristic spike during holiday periods. Overindulgence and abrupt changes of several lifestyle habits have been described as potential precipitating factors during such periods. Long travels, unhealthy diet, excessive or binge drinking and eating, decreased or increased physical activity, emotional and psychological stress, might all variably contribute to trigger an acute thrombotic event. Although the real causes of this "holiday phenomenon" remain speculative as yet, there is a widespread perception that they might represent preventable events like several other risk factors of both venous and arterial thrombosis. Beside drastic and unrealistic measures, such as canceling such holidays from the calendar, it seems reasonable to at least provide advice to patients about these "dangers," especially those individuals believed to be carrying a higher risk. Many (if not all) patients may ignore such advice and carry on regardless, but they should be given the benefit of informed choice. © Thieme Medical Publishers.

  15. Four bars inn; Four bars inn

    Nishiumi, T. [National Defense Academy, Kanagawa (Japan)

    1999-05-15

    The name Four Bars Inn puns on four drinking bars and four bars on a musical score. It is a public house sited on the busy St. Mary Street, Cardiff, England. During my stay in that town, I often attended the regular jam session that opened at the bar at nine o`clock every Monday evening. A jam session is an event in which any amateur player, and a professional artist occasionally, is allowed to come on the stage freely and to play jazz, the participation fee as low as 300-yen. It is an occasion that provides a friendly meeting of man and woman, young and old, everyone carrying a pint of ale. Senior people happily talking to young ones aged like their grandchildren certainly presents a heart-warming scene, which we scarcely encounter in Japan. The affection that the British entertain toward their domestic furnishings relayed down through many a generation may lead to their respect for senior citizens. I heartily look forward detecting like scenes some day at drinking spots in Japan where the consumption-happy days are over. (NEDO)

    2013-08-01

    Many people take holidays in sunny locations with the express aim of sunbathing. This may result in sunburn, which is a risk factor for skin cancer. We investigated 25 Danish sun seekers during a week's holiday in the Canary Islands. The percentage of body surface area with sunburn was determined by daily skin examinations by the same observer. Erythemally effective ultraviolet radiation (UVR) exposure was assessed with time-stamped personal dosimeters worn on the wrist. Volunteers reported their clothing cover and sunscreen use in diaries, and this information was used to determine body site-specific UVR doses after adjustment for sun protection factor. Remarkably, we found that all volunteers sunburned at some point. The risk of sunburn correlated significantly with the adjusted body site-specific UVR dose. Furthermore, there was also a significant relationship between the daily UVR dose and percentage of body surface area with sunburn. Our study shows that holiday UVR exposure results in a high risk of sunburn, which potentially increases the risk of skin cancer. Possible protection by melanogenesis is insufficient to protect against sunburn during a 1-week sun holiday. Finally, our data clearly support a substantial skin cancer risk from sun holidays. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  18. HOLIDAY AS SOCIAL INSTITUTE

    Galaktionova Nelli Anatolyevna

    2013-05-01

    Full Text Available The article deals with holiday as social institute, stages of its institutionalization, such as emergence of need; formation of general objects and ideology proving them; development of social norms and rules;practical adoption of rules and procedures; establishment sanction system; creation of statuses and role system. On the example of Russian festive tradition the general institutional signs of a holiday are described, it is specified that the majority of holidays are at a stage of cultural symbol search having the behavior code; system of ideas; utilitarian and cultural lines; installations and examples of behavior. Taking into consideration the view of Nelli Galaktionova, we can say, that these principles explain the popularity of the Victory Day Holiday and not stable Russian holiday on the 12-th of June- day of Russia. It is stated that the absence of the ritual prevents the popularity of holiday in society. In the article obvious and latent functions of a holiday as social institute are described - regulatory function, integrative, broadcasting, function of reproduction of the social relations, socializing, educational, guarding, forming the culture, communicative, sociocultural, actable, function of leisure and rest organization, adaptive and compensatory, function of removal of ethical regulations. According to the author of article, the holiday is a basis of formation of national and state and civil identity.

  19. HOLIDAY: THEORETICAL ASPECTS

    Cheban Yuliia

    2018-01-01

    Full Text Available The right to leave is part of the employee’s legal status. It has every employee who works under an employment contract. Ensuring the employee’s right to leave is guaranteed by the state. At the same time, the term “vacation” is a significant range of different phenomena that have features in different sectors of the economy, including agrarian space, different regions, different production conditions, etc. The foregoing complicates not only the basic definition of the term “vacation”, but also its organizational and accounting support. According to the legislation of Ukraine, the holiday is set by law, collective agreement or employment contract a certain number of calendar days of continuous rest, which are provided to the employee by the employer in a calendar year, with or without payment, with the preservation of the place of work (position by the employee at this time. The citizens of Ukraine, who are in labor relations with enterprises, institutions, organizations irrespective of the forms of ownership, type of activity and branch affiliation, are also entitled to leave, as well as work under an employment contract from an individual. The main features that are inherent to the overwhelming majority of the holidays are the following: the employee’s dismissal from performing labor duties, the preservation of the employee during the period of vacations of the place of work (position, payment. Domestic legislation, together with the scientific achievements of researchers, the concept of “vacation” is identified with the concept of “time”. The main characteristic features of the vacation include the guarantee of vacation by law; scope of leave; periodicity of holidays; definition of the length of leave in legislation; continuity of rest during the holiday period; connection of vacation with work experience; the main purpose of vacation; preservation of the place of work at the time of vacations; saving at the time of

  2. Impact of urbanization on the air pollution “holiday effect” in Taiwan

    Tan, Pei-Hua; Chou, Chia; Chou, Charles C.-K.

    2013-05-01

    The spatio-temporal characteristics of the “holiday effect”, defined as the difference in air pollutant concentrations between the holiday (Chinese New Year) and non-holiday periods during 1994-2008, and its association with the degree of urbanization in Taiwan are examined. Daily surface measurements of six major pollutants from 54 monitoring stations of the Taiwan Environmental Protection Administration are used. Holiday effects are found for almost all air pollutants in all divisions and individual stations. A widespread holiday effect with consistent signs suggests a high degree of urbanization over Taiwan. Holiday effects are stronger in the west than in the east, due to urban-rural differences, and have a distinct north-south difference in the west, due to different emission sources. In the spatial distribution, as the population (motor vehicle) number in the division increases, holiday effects of NOx, CO and NMHC are intensified. Holiday effects of pollutants can also be stronger when the associated dominant anthropogenic sources in the division have larger emissions. Both imply the association of a stronger holiday effect with a higher degree of urbanization in the division. In the temporal variation, on the other hand, holiday effects and pollutant concentrations tend to weaken and reduce in almost all the urban divisions for all six pollutants except O3. These weakening trends imply possible contributions of other effects, such as the mature state of urbanization for the urban division, the effective pollution-control measures and behavioral pattern changes.

  3. Etheostoma brevirostrum (Holiday Darter)

    Burkhead, Noel M.

    2015-01-01

    The life history of the Holiday Darter is incompletely known. Only reproductive behavior (Johnston and Shute 1997; Anderson 2009), habitat use, and spawning seasons (Anderson 2009) have been studied. However, based on similarity of life history attributes among snubnose darters (Carney and Burr 1989; Johnston and Haag 1996; Khudamrongsawat et al. 2005), the Holiday darter probably lives 3+ years and matures in the first year. It is likely a benthic omnivore, feeding primarily on chironomid (midge) larvae and other common orders of aquatic insects and occasional microcrustaceans. Spawning occurs from late March to early June, with most activity occurring in April. Based on four females from the Amicalola Creek system, fecundity ranged from 50 to 150 mature eggs, egg sizes ranged from 1.2mm to 1.6mm diameter. The Holiday Darter is an “egg attacher” (sensu Page and Swofford 1984). A spawning female is courted by multiple males, but a dominant (alpha) male aggressively rebuts encroaching males and defends a “roving territory” of the receptive female. The alpha male is the principal spawning partner although satellite males often rush a spawning pair. The receptive female slowly swims along the stream bottom, frequently stopping, apparently to assess substrate attributes, and selects each spawning site where only one or two eggs are spawned. The process is repeated and often covers several meters of stream bottom until the courted female finishes spawning and is abandoned by the alpha male. Water temperatures during spawning in Amicalola Creek and the upper Etowah River ranged 10 to 17° C (Anderson 2009).

  13. The Profile of Romanian Urban Inns

    Monica Maria Coroș

    2016-11-01

    Full Text Available This paper is the third of a series of studies dedicated to tourist inns on the Romanian market. The previous papers focused on the identification of the tourist inns that currently function on the domestic market. Further, their potential as rural facilities was highlighted and their authenticity was discussed. The relevance of this research is linked to the fact that in the early 1990s tourist inns were excluded from the lists of lodging and food-serving facilities, ceasing to be officially ranked. Consequently, the inns’ owners were forced to reclassify as other accepted types or, even worse, to function in the shadow economy , without any official ranking. Moreover, the absence of inns on the market and the incoherent development of certain types of lodgings in Romania, have also led to the fact that entrepreneurs and tourists tend to be confused and, sometimes, not able to differentiate one type of accommodation unit from another. The main purpose of this research is to determine the extent to which urban inns can contribute to the authenticity of the Romanian tourism. From a methodological perspective, the paper relies on both official data (collected and processed based on the official Lists of Hospitality Facilities and on the information available on specialized websites. Thorough analyses have been run in order to identify the tourist structures pretending to be inns, to further categorize and discuss them according to various criteria. The main findings and conclusions of this paper reveal that inns have the potential to contribute to the authenticity of Romania’s hospitality industry .

    We present the experimental investigation of superconductivity in unintentionally doped MBE grown InN samples with various InN film thicknesses. A significant change in resistivity was observed at 3.82 K, for an 1080 nm InN layer with carrier concentration n{sub 3D}=1.185x10{sup 19} cm{sup -3}. However, no significant resistance change was observed in the case of InN samples with carrier density of 1.024x10{sup 19} cm{sup -3}, 1.38x10{sup 19} cm{sup -3}, and thicknesses of 2070 and 4700 nm, respectively. The carrier density of all investigated samples was within the range of values between the Mott transition (2x10{sup 17} cm{sup -3}) and the superconductivity to metal transition (7x10{sup 20} cm{sup -3}). We believe that at lower temperatures ({sup 3}He) which we cannot achieve with our set-up, the phase transition in other samples is likely to be observed. The origin of the observed anisotropic type-II superconductivity is discussed (copyright 2011 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim) (orig.)

    2008-01-01

    We report on the properties of high quality HVPE InN and on successful subsequent MBE growth of InN layers with improved characteristics on HVPE InN template substrates. InN layers were grown by HVPE on GaN/sapphire HVPE templates. The (00.2) XRD rocking curve of the best InN layer (RC) had the FWHM of about 375 arc sec, being the narrowest XRD RCs ever reported for HVPE InN. Transmission Electron Microscopy (TEM) revealed that at the GaN/InN interface, the threading dislocations that come from GaN were transmitted into the InN layer. We estimated the dislocation density in HVPE grown InN to be in the low 10 9 cm -2 range. Reflection high energy electron diffraction (RHEED) confirmed monocrystalline structure of the InN layers surface. Layers photoluminescence (PL) showed edge emission around 0.8 eV. Hall measured free electron concentration was in the range of 10 19 -10 20 cm -3 and electron mobility was ∝200 cm 2 /V s. MBE growth of InN was performed on the HVPE grown InN template substrate demonstrating the improvement of material quality in the case of homo-epitaxial growth of InN. Demonstration of the high quality HVPE InN materials opens a new way for InN substrate development. (copyright 2008 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim) (orig.)

    We report on metal-organic vapor phase epitaxial growth of (1122) InN on (1122) GaN templates on m-plane (1010) sapphire substrates. The in-plane relationship of the (1122) InN samples is [1123] InN ‖‖[0001] sapphire and [1100] InN ‖‖[1210] sapphire , replicating the in-plane relationship of the (1122) GaN templates. The surface of the (1122) InN samples and the (1122) GaN templates shows an undulation along [1100] InN,GaN , which is attributed to anisotropic diffusion of indium/gallium atoms on the (1122) surfaces. The growth rate of the (1122) InN layers was 3-4 times lower compared to c-plane (0001) InN. High resolution transmission electron microscopy showed a relaxed interface between the (1122) InN layers and the (1122) GaN templates, consistent with x-ray diffraction results. Basal plane stacking faults were found in the (1122) GaN templates but they were terminated at the InN/(1122) GaN interface due to the presence of misfit dislocations along the entire InN/GaN interface. The misfit dislocations were contributed to the fully relaxation and the tilts of the (1122) InN layers. X-ray photoelectron spectroscopy was used to determine the polarity of the grown (1122) InN sample, indicating an In-polar (1122) InN. The valence band maximum was determined to be at (1.7 ± 0.1) eV for the (1122) InN sample, comparable to In-polar c-plane InN.

    2006-01-01

    We have succeeded in dramatically decreasing the density of dislocations in InN by regrowing InN films on micro-facetted N-polar InN templates. The micro-facetted N-polar InN templates were formed by wet etching in a 10 mol/l KOH solution. InN films were regrown on the micro-facetted N-polar InN templates and on flat surface N-polar InN templates for comparison by radio-frequency plasma-assisted molecular beam epitaxy. InN regrown on micro-facetted InN had considerably smaller twist distribution than that grown on the flat InN templates. From transmission electron microscopy observation, it was confirmed that the InN grown on the micro-facetted InN template had much lower density of dislocations than that grown on the flat InN template, and moreover the propagation of edge dislocations was almost completely terminated at the interface between the regrown InN and the micro-facetted InN template. Based on the results, we propose that regrowth of InN on micro-facetted InN templates is an effective way to obtain high-quality InN films. (copyright 2006 WILEY-VCH Verlag GmbH and Co.

    We report a systematic investigation on Mg doped InN epilayers grown by radio-frequency plasma-assisted molecular beam epitaxy. Electrolyte capacitance voltage (ECV) combined with thermopower measurements find p-type conduction over an Mg concentration range. For InN:Mg in this p-type 'window' the Seebeck coefficients dramatically change their signs from negative to positive when the thickness of undoped InN interlayer decreases to zero. This notable sign change of Seebeck coefficient explains the previous inconsistency between ECV and thermopower results and confirms the existence of mobile holes in the InN:Mg. Taking into account the undoped InN interlayer, the hole density and mobility are extracted.

    2008-01-01

    One-dimensional wurtzite InN nanowires and zincblende InN nanorods are prepared by chemical vapour deposition (CVD) method on natural cleavage plane (110) of GaAs. The growth direction of InN nanowires is [100], with wurtzite structure. The stable crystal structure of InN is wurtzite (w-InN), zincblende structure (z-InN) is only reported for 2D InN crystals before. However, in this work, the zincblende InN nanorods [011] are synthesized and characterized. The SEM and TEM images show that every nanorod shapes a conical tip, which can be explained by the anisotropy of growth process and the theory of Ehrlich–Schwoebel barrier.

  13. Observation of a "holiday effect ": a case of Chinese New Year in Taiwan

    Tan, Pei-Hua; Chou, Chia; Chen, Pen-Yuan; Sun, Chen-Yi; Wu, Bo-Lin

    2010-05-01

    Our study was an attempt to conduct a comprehensive and systematical examination of the 'holiday effect', defined as the difference in air pollutant concentrations between holiday and non-holiday periods. This holiday effect can be applied to other countries with similar national or cultural holidays. Hourly and daily surface measurements of six major air pollutants from fifty-four air quality monitoring stations of the Environmental Protection Administration in Taiwan during the Chinese New Year (CNY) and non-Chinese New Year (NCNY) periods of 1994-2008 were used. The air pollutant concentrations were significantly different between holidays (CNY) and non-holidays (NCNY), in almost all the Taiwan area, except CO in the eastern part which is a relatively less-developed area. The industrial development of Taiwan extends from the north to the south; and then from the west to the east, due to the inconvenient transportation in the east. The difference percentage, defined as the concentration difference of CNY minus NCNY relative to the NCNY concentration, is highly related to the degree of industrialization. The difference percentages of NOx, CO, NMHC, O3, SO2, and PM10 are more in the west than in the east. Over the western part of Taiwan, the difference percentages of NOx, CO, NMHC and O3 are more in the north than in the south; that of SO2basically follows a similar trend but is more in the middle Taiwan, which might be related to emission change of a major coal-fired power plant. The difference percentage of PM10 over the western Taiwan is more in the south than in the north, probably due to stronger dust storm impacts on the northern Taiwan, where the dust storm sometimes occurs to 'pollute' the clean air during the CNY period, and then causes fewer difference percentage.

  14. High electron mobility InN

    Jones, R. E.; Li, S. X.; Haller, E. E.; van Genuchten, H. C. M.; Yu, K. M.; Ager, J. W. III; Liliental-Weber, Z.; Walukiewicz, W.; Lu, H.; Schaff, W. J.

    2007-01-01

    Irradiation of InN films with 2 MeV He + ions followed by thermal annealing below 500 deg. C creates films with high electron concentrations and mobilities, as well as strong photoluminescence. Calculations show that electron mobility in irradiated samples is limited by triply charged donor defects. Subsequent thermal annealing removes a fraction of the defects, decreasing the electron concentration. There is a large increase in electron mobility upon annealing; the mobilities approach those of the as-grown films, which have 10 to 100 times smaller electron concentrations. Spatial ordering of the triply charged defects is suggested to cause the unusual increase in electron mobility

  15. Air pollution holiday effect in metropolitan Kaohsiung

    Tan, P.; Chen, P. Y.

    2014-12-01

    Different from Taipei, the metropolitan Kaohsiung which is a coastal and industrial city has the major pollution sources from stationary sources such as coal-fired power plants, petrochemical facilities and steel plants, rather than mobile sources. This study was an attempt to conduct a comprehensive and systematical examination of the holiday effect, defined as the difference in air pollutant concentrations between holiday and non-holiday periods, over the Kaohsiung metropolitan area. We documented evidence of a "holiday effect", where concentrations of NOx, CO, NMHC, SO2 and PM10 were significantly different between holidays and non-holidays, in the Kaohsiung metropolitan area from daily surface measurements of seven air quality monitoring stations of the Taiwan Environmental Protection Administration during the Chinese New Year (CNY) and non-Chinese New Year (NCNY) periods of 1994-2010. Concentrations of the five pollutants were lower in the CNY than in the NCNY period, however, that of O3 was higher in the CNY than in the NCNY period and had no holiday effect. The exclusion of the bad air quality day (PSI > 100) and the Lantern Festival Day showed no significant effects on the holiday effects of air pollutants. Ship transportation data of Kaohsiung Harbor Bureau showed a statistically significant difference in the CNY and NCNY period. This difference was consistent with those found in air pollutant concentrations of some industrial and general stations in coastal areas, implying the possible impact of traffic activity on the air quality of coastal areas. Holiday effects of air pollutants over the Taipei metropolitan area by Tan et al. (2009) are also compared.

  17. Bandtail characteristics in InN thin films

    Shen, W.Z.; Jiang, L.F.; Yang, H.F.; Meng, F.Y.; Ogawa, H.; Guo, Q.X.

    2002-01-01

    The Urbach bandtail characteristics in InN thin films grown by radio-frequency magnetron sputtering on sapphire (0001) substrates have been investigated both theoretically and experimentally. The bandtail parameter in InN thin films has been obtained by temperature-dependent transmission spectra, with the aid of a detailed calculation of the transmission profile. A bandtail model based on the calculation of density of occupied states and the carrier-phonon interaction has been employed to analyze the temperature-dependent bandtail characteristics. The bandtail parameter is in the range of 90-120 meV in the InN thin film. It is found that the carrier-phonon interaction in InN is weak and the structural disorder contribution (∼90 meV) dominates over the interactive terms. The high structural disorder in InN thin films may relate to the high nonradiative recombination centers

  1. Prognosis following cancer surgery during holiday periods.

    Lagergren, Jesper; Mattsson, Fredrik; Lagergren, Pernilla

    2017-11-15

    Surgery is the mainstay curative treatment in most cancer. We aimed to test the new hypothesis that cancer surgery performed during holiday periods is associated with worse long-term prognosis than for non-holiday periods. This nationwide Swedish population-based cohort study included 228,927 patients during 1997-2014 who underwent elective resectional surgery for a cancer where the annual number of resections was over 100. The 16 eligible cancer sites were grouped into 10 cancer groups. The exposure, holiday periods, was classified as wide (14-weeks) or narrow (7-weeks). Surgery conducted inside versus outside holiday periods was compared regarding overall disease-specific (main outcome) and overall all-cause (secondary outcome) mortality. Cox regression provided hazard ratios (HR) with 95% confidence intervals (CI) adjusted for age, sex, comorbidity, hospital volume, calendar period and tumor stage. Surgery conducted during wide and narrow holiday periods were associated with increased HRs of disease-specific mortality for cancer of the breast (HR 1.08, 95% CI 1.03-1.13 and HR 1.06, 95% CI 1.01-1.12) and possibly of cancer of the liver-pancreas-bile ducts (HR 1.09, 95% CI 0.99-1.20 and HR 1.12, 95% CI 0.99-1.26). Sub-groups with cancer of the colon-rectum, head-and-neck, prostate, kidney-urine bladder and thyroid also experienced statistically significantly worse prognosis following surgery conducted during holiday periods. No influence of surgery during holiday was detected for cancer of the esophagus-stomach, lung or ovary-uterus. All-cause HRs were similar to the disease-specific HRs. The prognosis following cancer surgery might not be fully maintained during holiday periods for all cancer sites. © 2017 UICC.

    2006-01-01

    Infrared reflectance measurements of a series of InN thin films have been performed and attempt to derive carrier concentration and other physical constants for InN thin film characterization. Fitting calculations are performed by use of the dielectric function equation based on phonon-plasmon coupling model. Longitudinal and transverse optical phonon frequencies, plasma frequency and their damping parameters can be derived from fitting. From those results, electrical and phonon properties of InN and characterization of films are discussed. (copyright 2006 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim) (orig.)

    The optical properties of InN are investigated theoretically by employing the projector augmented wave (PAW) method within Green's function and the screened Coulomb interaction approximation (GW o ). The calculated results are compared to previously reported calculations which use local density approximation combined with the scissors-operator approximation. The results of the present calculation are compared with reported values of the InN bandgap and with low temperature near infrared luminescence measurements of InN films deposited by a modified Ion Beam Assisted Deposition technique.

    2012-04-15

    Structural and elastic properties of InN nanowires (NWs) have been investigated. It was observed that the NWs bend spontaneously or upon meeting an obstacle in their growth path at angles that are multiples of 30 . Lithographically patterned trenches and barriers were found to influence the growth direction of the NWs, which depending on the angle of incidence, grew along the barrier or got deflected from it. Young's modulus of InN NWs, measured by three point bending method using a NW suspended across a trench, was found to be 266 GPa, which is in between the moduli of bulk and thin film InN. Overall, the InN NW properties were found to be very suitable for applications in nanoelectromechanical systems (NEMS) and sensors. (Copyright copyright 2012 WILEY-VCH Verlag GmbH and Co.

    2009-12-01

    Holiday ornament injuries in children have not been well documented in the medical literature. Our aim was to investigate the patterns of injuries sustained from these ornaments as a first measure toward prevention. This was a retrospective cohort analysis of all patients examined in an urban pediatric emergency department over a 13-year period ending in March 2008 for holiday ornament-related injuries. Cases were identified using a computer-assisted text query followed by a manual chart review. Data collected from each chart included the child's age, sex, injury characteristics, physical examination findings, radiographic imaging, interventions, and disposition. To analyze injury rates over the years, we used a multiplicative Poisson model allowing varying exposures. Over the study period, we identified 76 eligible patients. The median age was 2 years (interquartile range, 1.17-3.3 years); 44.7% were female. Forty-three of the 76 cases (53.9%) involved ingestions: 35 were of holiday ornaments, and 8 were of light bulbs. All but one of these ornaments were made of glass. In 28%, there was an associated bleed either from the mouth or as a delayed gastrointestinal bleed. Other patients experienced lacerations (27.6%), eye injuries (5.1%), and minor electrocution injury (2.5%). Imaging was performed in 85%. A subspecialty consult was obtained in 23%, primarily addressing a foreign body ingestion or removal after skin exploration. The incidence rate has not changed over the years. Holiday ornament-related injuries primarily involve foreign body ingestions and glass-related injuries. Over half of the injuries involved small light bulbs and ornaments made of glass placed at the level a toddler can reach. Pediatricians are advised to discuss these points with families during holiday season.

    Shetty, Arjun; Kumar, Mahesh; Roull, Basanta; Vinoy, K J; Krupanidhj, S B

    2016-01-01

    Self-assembled InN quantum dots (QDs) were grown on Si(111) substrate using plasma assisted molecular beam epitaxy (PA-MBE). Single-crystalline wurtzite structure of InN QDs was confirmed by X-ray diffraction. The dot densities were varied by varying the indium flux. Variation of dot density was confirmed by FESEM images. Interdigitated electrodes were fabricated using standard lithog- raphy steps to form metal-semiconductor-metal (MSM) photodetector devices. The devices show strong infrared response. It was found that the samples with higher density of InN QDs showed lower dark current and higher photo current. An explanation was provided for the observations and the experimental results were validated using Silvaco Atlas device simulator.

    Butcher, Kenneth Scott A.; Alexandrov, Dimiter; Terziyska, Penka; Georgiev, Vasil; Georgieva, Dimka; Binsted, Peter W.

    2012-01-01

    InN thin films were grown by a new technique, migration enhanced afterglow (MEAglow), a chemical vapour deposition (CVD) form of migration enhanced epitaxy (MEE). Here we describe the apparatus used for this form of film deposition, which includes a scalable hollow cathode nitrogen plasma source. Initial film growth results for InN are also presented including atomic force microscopy (AFM) images that indicate step flow growth with samples having root mean square (RMS) surface roughness of as little as 0.103 nm in some circumstances for film growth on sapphire substrates. X-ray diffraction (XRD) results are also provided for samples with a full width half maximum (FWHM) of the (0002) ω-2θ peak of as little as 290 arcsec. Low pressure conditions that can result in damage to the InN during growth are described. (Copyright copyright 2012 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim)

  20. InN{0001} polarity by ion scattering spectroscopy

    Walker, M.; Veal, T.D.; McConville, C.F.; Lu, Hai; Schaff, W.J.

    2005-01-01

    The polarity of a wurtzite InN thin film grown on a c-plane sapphire substrate with GaN and AlN buffer layers has been investigated by co-axial impact collision ion scattering spectroscopy (CAICISS). Time of flight (TOF) spectra of He + ions scattered from the surface of the InN film were taken as a function of the incident angles of the primary 3 keV He + ions. From the TOF spectra, the polar angle-dependence of the In scattered intensity was obtained. Comparison of the experimental polar-angle dependence of the In CAICISS signal intensity with simulated results for the various volume ratios of (0001)- and (000 anti 1)-polarity domains indicated that the InN film is approximately 75% In-polarity and 25% N-polarity.

    2012-01-01

    We investigate the influence of a low-growth-rate InN buffer layer on structural and optical properties of wurtzite nanocrystalline InN films deposited on Si(111) substrates by reactive radio-frequency sputtering. The deposition conditions of the InN buffer layer were optimized in terms of morphological and structural quality, leading to films with surface root-mean-square roughness of ∼ 1 nm under low-growth-rate conditions (60 nm/h). The use of the developed InN buffer layer improves the crystalline quality of the subsequent InN thick films deposited at high growth rate (180 nm/h), as confirmed by the narrowing of X-ray diffraction peaks and the increase of the average grain size of the layers. This improvement of the structural quality is further confirmed by Raman scattering spectroscopy measurements. Room temperature PL emission peaking at ∼ 1.58 eV is observed for InN samples grown with the developed buffer layer. The crystal and optical quality obtained for InN films grown on Si(111) using the low-growth-rate InN buffer layer become comparable to high-quality InN films deposited directly on GaN templates by RF sputtering. - Highlights: ► Improved RF-sputtered InN films on Si(111) using a low-growth-rate InN buffer layer. ► Enhanced structural quality confirmed by X-ray diffraction and Raman measurements. ► Room-temperature photoluminescence emission at 1.58 eV. ► InN films deposited with buffer layer on Si comparable to InN LAYERS on GaN templates.

    We study the excitation wavelength dependence of the Raman spectra of InN nanowires. The E{sub 1}(LO) phonon mode, which is detected in backscattering configuration because of light entering through lateral faces, exhibits an upward frequency shift that can be explained by Martin's double resonance. The E{sub 1} (LO)/E{sub 2}{sup h} intensity ratio increases with the excitation wavelength more rapidly than the A{sub 1}(LO)/E{sub 2}{sup h} ratio measured in InN thin films.

  4. Electrochemical corrosion behavior of carbon steel with bulk coating holidays

    2006-01-01

    With epoxy coal tar as the coating material, the electrochemical corrosion behavior of Q235 with different kinds of bulk coating holidays has been investigated with EIS (Electrochemical Impedance Spectroscopy) in a 3.5vol% NaCl aqueous solution.The area ratio of bulk coating holiday to total coating area of steel is 4.91%. The experimental results showed that at free corrosionpotential, the corrosion of carbon steel with disbonded coating holiday is heavier than that with broken holiday and disbonded & broken holiday with time; Moreover, the effectiveness of Cathodic Protection (CP) of carbon steel with broken holiday is better than that with disbonded holiday and disbonded & broken holiday on CP potential -850 mV (vs CSE). Further analysis indicated that the two main reasons for corrosion are electrolyte solution slowly penetrating the coating, and crevice corrosion at steel/coating interface near holidays. The ratio of impedance amplitude (Z) of different frequency to minimum frequency is defined as K value. The change rate of K with frequency is related to the type of coating holiday.

    We report on a systematic growth study of the nucleation process of InN nanowires on Si(1 1 1) substrates using plasma assisted molecular beam epitaxy (PAMBE). Samples are grown with various substrate temperatures and III/V ratios. Scanning electron microscopy, X-ray diffraction spectroscopy, energy dispersive X-ray spectroscopy, and photoluminescence are carried out to map out the variation in structural and optical properties versus growth conditions. Statistical averages of areal density, height, and radius are mapped as a function of substrate temperature and III/V ratio. Three different morphological phases are identified on the growth surface: InN, α-In and β-In. Based on SEM image analysis of samples grown at different conditions, the formation mechanism of these phases is proposed. Finally, the growth phase diagram of PAMBE grown InN on Si under N-rich condition is presented, and tapered versus non-tapered growth conditions are identified. It is found that high growth temperature and low III/V ratio plays a critical role in the growth of non-tapered InN nanowires.

  7. The influence of school holiday timing on epidemic impact.

    Eames, K T D

    2014-09-01

    The impact of reactive school closure on an epidemic is uncertain, since it is not clear how an unplanned closure will affect social mixing patterns. The effect of school holidays on social mixing patterns is better understood. Here, we use mathematical models to explore the influence of the timing of school holidays on the final size and peak incidence of an influenza-like epidemic. A well-timed holiday can reduce the impact of an epidemic, in particular substantially reducing an epidemic's peak. Final size and peak incidence cannot both be minimized: a later holiday is optimal for minimizing the final size, while an earlier holiday minimizes peak incidence. Using social mixing data from the UK, we estimated that, had the 2009 influenza epidemic not been interrupted by the school summer holidays, the final size would have been about 20% larger and the peak about 170% higher.

    2005-01-01

    Indium nitride (InN) films were deposited on Si(100) substrates using a radiofrequency (RF) plasma-assisted reactive ion beam sputtering deposition technique at various substrate temperatures. The X-ray diffraction patterns of the InN films suggest that the InN films deposited at substrate temperatures up to 370 deg C were cubic crystalline InN; and at 500 deg C, the InN film was hexagonal crystalline InN. In a scanning electron microscope image of the InN film surface, facets of cubic single-crystalline InN grains were clearly observed on the InN film deposited at 370 deg C. The inclusion of metallic indium appeared on the InN film deposited at 500 deg C

    2017-06-01

    Full Text Available After 2010, the study of present-day holidays established itself as an original tool for the study of society in Slovak ethnology. In the first stage, the research team of the Institute of Ethnology SAS focused on the empirical research of the specific contexts of the term holiday in Slovakia and mapped the range of situations which are designated by people as holidays today. The term holiday means the interruption of the daily routine, a moment commemorated on a cyclical basis or a period accompanied by normative or ritual acts and with an ascribed symbolic meaning. Our research showed that apart from identification, ritual and spiritual functions which are important for individuals or communities, as commonly studied by ethnology, holidays also fulfil a number of practical functions at present. After the discovery of the manifold overlaps of this phenomenon with the on-going social processes, the focus of ethnology has shifted to society as such and on its reflection in the mirror of holidays. Through an analysis of empirical materials from the observation and ethnographic description of the events in the public space during holidays, the study of the holiday legislation, the activities of various institutions the production of printed and electronic media, business and advertising, which create the current content and the ways of celebrating holidays, it was possible to obtain a basis for a specific testimony about the present-day social processes in the Slovak Republic. In this context, this study is dedicated to the following relations: holidays and politics, holidays and economy, and holidays and citizens.

    The cardiovascular effects of alcohol are well known. However, most research has focused on the beneficial effects (the 'French paradox') of moderate consumption or the harmful consequences, such as dilated cardiomyopathy, associated with heavy consumption over an extended period. An association between the ingestion of acute alcohol and onset of cardiac arrhythmias was first reported in the early 70's. In 1978, Philip Ettinger described 'Holiday heart syndrome' (HHS) for the first time, as the occurrence, in healthy people without heart disease known to cause arrhythmia, of an acute cardiac rhythm disturbance, most frequently atrial fibrillation, after binge drinking. The name is derived from the fact that episodes were initially observed more frequently after weekends or public holidays. Since the original description of HHS, 34 years have passed and new research in this field has increased the volume of knowledge related to this syndrome. Throughout this paper the authors will comprehensively review most of the available data concerning HHS and highlight the questions that remain unresolved.

  14. Industrial Pastoral: Lake Macquarie Coal Miners’ Holidays

    Russell McDougall

    2010-11-01

    Full Text Available As Stephen Page and Joanne Connell note in their mapping of the field, leisure studies is a largely post-war development, evolving internationally out of geography, economics, sociology and a range of other disciplines mostly in the social sciences rather than the humanities. Historians have not ignored the subject – there are plenty of historical studies of sports and recreation, the development of national parks, and so on. Yet, while leisure clearly has a vital and dynamic relation to work – culturally, politically, psychologically – labour historians in Australia appear to have been less interested in this area of research. We, the authors of this article, are primarily literary scholars rather than historians, but we have been puzzled by this apparent neglect. It is not our brief to examine the contemporary meanings of ‘leisure’ in relation to ‘work’ (or ‘forced labour,’ to adopt Guy Standing’s important twenty-first century distinction. Instead, our own study of coal miners’ holidays around Lake Macquarie from the late nineteenth and into the second half of the twentieth century considers the bygone rituals and activities of their holidaying from the vantage point of our own present location in an age where ‘simulation and nostalgia lie at the heart of everyday life.’ The article includes memoir and creative writing along with theory and analysis.

  16. Impact of urbanization and industrial development on holiday effect

    2012-04-01

    Our study is to examine the "holiday effect", defined as the difference in air pollutant concentrations between holiday and non-holiday periods, and associated factors controlling the strength of holiday effect in Taiwan. This holiday effect can be applied to other countries with similar national or cultural holidays. Daily surface measurements of six major air pollutants from fifty-four air quality monitoring stations of the Taiwan Environmental Protection Administration (TEPA) during the Chinese New Year (CNY) and non-Chinese New Year (NCNY) periods of 1994-2008 are used. The air pollutant concentrations are significantly different between the CNY and NCNY periods, in almost all the Taiwan area, except CO in the eastern part which is a relatively less-developed area. The strengths of holiday effects of NOx, CO, NMHC and O3 are larger in the north than in the south, and those of SO2 and PM10 are larger in the south than in the north. Factors controlling the strength of holiday effect such as the degree of urbanization and anthropogenic sources are examined. The population number and motor vehicle number rather than the population number density and motor vehicle number density have a significantly positive relationship with the strengths of holiday effects of NOx, CO and NMHC. The strengths of holiday effects of NOx and CO are mainly contributed from mobile sources and those of SO2 and PM10 are from stationary sources and that of NMHC is from both mobile and stationary sources. As the dominant anthropogenic sources in the air quality division have larger emissions, holiday effect strengths of associated air pollutants are found to be stronger.

Qom with roughly 17 million tourists in 2005 was the second religious tourism center in Iran. This study was designed to determine the environmental health criteria of Qom hotels and inns in 2007.MethodsThis descriptive - cross sectional study was carried out based on a standard check list of substance of edible, drinkable, cosmetic and hygienic products law from ministry of health and medical sciences. The checklist included 73 questions which were completed by face to face interviews and sanitary inspections. After analyzing the results of each residential center, the questionnaires were classified into three categories: hygienic (over 80 score, sanitary (40-79 and unacceptable centers (less than 40. The data were presented and analyzed by descriptive and analytical statistical methods such as X 2 and Fisher exact test.ResultsThe percentages of hygienic, sanitary and unacceptable conditions of hotels and inns were 35.5, 54.8 and 9.7, respectively. There was a direct relationship between academic degree of residential managers and the validity of employees health card (P=0.042 ConclusionBased on this the research, the environmental status of Qom hotels and inns was in relatively desirable conditions. Residential places with unacceptable condition were almost located in the old region of the city (e.g. around the Holly Shrine. Due to the structural failures, architectural problems and tremendous cost for repairs, it’s better that their activities be stopped and banned by government. With regard to the high percentage of hotels with sanitary conditions, at least improvements in health conditions accompanied by training and supervision are recommended.

  2. Crystallographic deterioration of MOVPE InN during the growth

    Sugita, K.; Nagai, Y.; Houchin, Y.; Hashimoto, A.; Yamamoto, A.

    2007-01-01

    This paper reports the crystallographic degradation of MOVPE InN during the growth. Using FWHMs of X-ray rocking curve, tilt ((0002)) and twist ((10-10)) angle distributions are evaluated and effects of the major growth parameters, such as growth temperature, growth time and with/without GaN buffer in the degradation, are revealed. With increasing either thickness of grown InN or growth temperature up to 600 C, the tilt angle distribution is markedly increased, indicating the crystallographic degradation of grown films. The use of a GaN buffer reduces such degradation. Since the twist angle distribution is scarcely changed by such growth parameters, the destruction of InN crystals during growth and annealing is concluded to be anisotropic. The trends of the crystallographic degradation revealed here are in good agreement with those for the electrical and optical degradation previously reported.

    Indium nitride (InN) sphere-shaped micro crystals and nano crystals were made using sol-gel method. The crystalline size of the samples were calculated using X-ray diffraction, which were found to increase with the increase of nitridation temperature and time. High resolution-transmission electron microscopy images exhibited the distinct sphere shape of InN with different size of micro and nanometers. The calculated band gap of InN spheres using photo luminescence and UV-visible absorption spectra, was found to be 1.2 eV. Optical phonon modes of InN were determined from micro-Raman studies.

  4. Convergence of valence bands for high thermoelectric performance for p-type InN

    Li, Hai-Zhu; Li, Ruo-Ping; Liu, Jun-Hui; Huang, Ming-Ju

    2015-01-01

    Band engineering to converge the bands to achieve high valley degeneracy is one of effective approaches for designing ideal thermoelectric materials. Convergence of many valleys in the valence band may lead to a high Seebeck coefficient, and induce promising thermoelectric performance of p-type InN. In the current work, we have systematically investigated the electronic structure and thermoelectric performance of wurtzite InN by using the density functional theory combined with semiclassical Boltzmann transport theory. Form the results, it can be found that intrinsic InN has a large Seebeck coefficient (254 μV/K) and the largest value of Z e T is 0.77. The transport properties of p-type InN are better than that of n-type one at the optimum carrier concentration, which mainly due to the large Seebeck coefficient for p-type InN, although the electrical conductivity of n-type InN is larger than that of p-type one. We found that the larger Seebeck coefficient for p-type InN may originate from the large valley degeneracy in the valence band. Moreover, the low minimum lattice thermal conductivity for InN is one key factor to become a good thermoelectric material. Therefore, p-type InN could be a potential material for further applications in the thermoelectric area.

    We report on the improvement of the surface morphology of a-plane InN films grown by RF molecular beam epitaxy. By using low-temperature (LT) InN buffer layers, we could successfully obtain InN films with a smooth surface. The full width at half maximum values of the X-ray diffraction (11-20) rocking curve along the [0001]InN direction were 2870 arcsec and 3410 arcsec for a-plane InN samples grown at 500 C with and without LT-InN buffer layers, respectively. Thus, we could improve also the crystalline quality of a-plane InN films by using LT-InN buffer layers. We observed strong polarization anisotropy in the photoluminescence spectra of a-plane InN, which is typical of nonpolar wurtzite III-nitride films. (copyright 2008 WILEY-VCH Verlag GmbH and Co.

  6. The energy requirement of holidays and household reduction options

    Van den Berg, M.; Vringer, K.

    1999-12-01

    Like all consumer products and services, holidays require energy. The aim of this study is to give insight to the energy consumption for holidays of Dutch households and to suggest options to reduce this energy demand. To examine the energy consumption for holidays, nine holiday packages are composed, each representing a large group of Dutch vacationers. The packages describe the destination, means of transport, duration, accommodation and number of vacationers. The average energy requirement for the accommodation and transport for long summer holidays is 12.5 GJ per Dutch household, excluding the energy requirement for food and activities. About 10% of the Dutch households, the ones that travel by plane to their holiday destination, consume 70% of the total amount of energy all households require for holiday purposes. This is mainly due to the distance travelled, rather than to the chosen means of transport. If the travelled distances will be reduced by 50% and all nights are spent in a tent, the average household energy requirement would be 6.1 GJ, a reduction of more than 50%. 36 refs

  7. Air pollution "holiday effect" resulting from the Chinese New Year

    Tan, Pei-Hua; Chou, Chia; Liang, Jing-Yi; Chou, Charles C.-K.; Shiu, Chein-Jung

    Our study was an attempt to conduct a comprehensive and systematical examination of the holiday effect, defined as the difference in air pollutant concentrations between holiday and non-holiday periods. This holiday effect can be applied to other countries with similar national or cultural holidays. Hourly and daily surface measurements of six major air pollutants from thirteen air quality monitoring stations of the Taiwan Environmental Protection Administration during the Chinese New Year (CNY) and non-Chinese New Year (NCNY) periods were used. We documented evidence of a "holiday effect", where air pollutant concentrations were significantly different between holidays (CNY) and non-holidays (NCNY), in the Taipei metropolitan area over the past thirteen years (1994-2006). The concentrations of NO x, CO, NMHC, SO 2 and PM 10 were lower in the CNY than in the NCNY period, while the variation in the concentration of O 3 was reversed, which was mainly due to the NO titration effect. Similar differences in these six air pollutants between the CNY and NCNY periods were also found in the diurnal cycle and in the interannual variation. For the diurnal cycle, a common traffic-related double-peak variation was observed in the NCNY period, but not in the CNY period. Impacts of dust storms were also observed, especially on SO 2 and PM 10 in the CNY period. In the 13-year period of 1994-2006, decreasing trends of NO x and CO in the NCNY period implied a possible reduction of local emissions. Increasing trends of SO 2 and PM 10 in the CNY period, on the other hand, indicated a possible enhancement of long-range transport. These two mechanisms weakened the holiday effect.

  8. Structural anisotropy of nonpolar and semipolar InN epitaxial layers

    We present a detailed study of the structural characteristics of molecular beam epitaxy grown nonpolar InN films with a- and m-plane surface orientations on r-plane sapphire and (100) γ-LiAlO2, respectively, and semipolar (101¯1) InN grown on r-plane sapphire. The on-axis rocking curve (RC) widths were found to exhibit anisotropic dependence on the azimuth angle with minima at InN [0001] for the a-plane films, and maxima at InN [0001] for the m-plane and semipolar films. The different contributions to the RC broadening are analyzed and discussed. The finite size of the crystallites and extended defects are suggested to be the dominant factors determining the RC anisotropy in a-plane InN, while surface roughness and curvature could not play a major role. Furthermore, strategy to reduce the anisotropy and magnitude of the tilt and minimize defect densities in a-plane InN films is suggested. In contrast to the nonpolar films, the semipolar InN was found to contain two domains nucleating on zinc-blende InN(111)A and InN(111)B faces. These two wurtzite domains develop with different growth rates, which was suggested to be a consequence of their different polarity. Both, a- and m-plane InN films have basal stacking fault densities similar or even lower compared to nonpolar InN grown on free-standing GaN substrates, indicating good prospects of heteroepitaxy on foreign substrates for the growth of InN-based devices.

  16. An unhealthy holiday on Lake Bolsena

    Lucio Brugioni

    2013-03-01

    Full Text Available A 70-year old man (OL was hospitalized due to fever (up to 40°C associated with malaise and abdominal pain. Tests showed hypereosinophilic syndrome, and increased liver and inflammation indexes. Abdominal echography showed a nonhomogeneous liver and the spleen was enlarged. Abdominal computed tomography showed multiple abscesses on the liver. The patient reported that he had recently gone on holiday to Lake Bolsena where he had eaten raw fish. A specialist in infectious diseases confirmed that in that area there is an infestation of Opisthorchis felineus. Analysis of blood and stool samples confirmed the presence of this parasite. The patient was treated with praziquantel with resolution of fever and improvement in clinical tests and general condition. Opisthorchis felineus is a parasite that commonly infects dogs and cats. Infection is sometimes transmitted to man and is usually related to eating raw fish. The parasite enters the liver and its eggs are found in the patient’s stool samples. Acute symptoms are: fever, diarrhea, abdominal pain, and malaise. Hypereosinophilic syndrome and increase in liver index are typical. Chronic infection could result in cholangiocarcinoma. Presence of the parasite is confirmed through specific analysis of blood and stool. Therapy consists of praziquantel or, as second choice, abendazol. In the 20th century, there were 4 epidemics in Italy, on Lakes Trasimeno and Bolsena in Central Italy. The latest epidemic was reported in that area in summer 2012.

  17. Evaluation of threading dislocation densities in In- and N-face InN

    Gallinat, C. S.; Koblmueller, G.; Wu, Feng; Speck, J. S.

    2010-01-01

    The threading dislocation (TD) structure and density has been studied in In- and N-face InN films grown on GaN by plasma-assisted molecular beam epitaxy. The TD densities were determined by nondestructive x-ray diffraction rocking curve measurements in on-axis symmetric and off-axis skew symmetric geometries and calibrated by transmission electron microscopy measurements. TD densities were dominated by edge-type TDs with screw-component TDs accounting for less than 10% of the total TD density. A significant decrease in edge-type TD density was observed for In-face InN films grown at increasingly higher substrate temperatures. In-face InN films grown with excess In exhibited lower TD densities compared to films grown under N-rich conditions. The edge-type TD density of N-face InN films was independent of substrate temperature due to the higher allowable growth temperatures for N-face InN compared to In-face InN. TD densities in In-face InN also showed a strong dependence on film thickness. Films grown at a thickness of less than 1 μm had higher TD densities compared with films grown thicker than 1 μm. The lowest measured TD density for an In-face InN film was ∼1.5x10 10 /cm 2 for 1 μm thick films.

    We have grown InN films on MgAl{sub 2}O{sub 4}(111) substrates with atomically flat surfaces using pulsed laser deposition (PLD) and compared their structural properties with those grown on (Mn,Zn)Fe{sub 2}O{sub 4}(111) substrates. It has been revealed that InN(0001) films grow on MgAl{sub 2}O{sub 4}(111) with an in-plane epitaxial relationship of InN[1 anti 100]//MgAl{sub 2}O{sub 4}[1 anti 10], achieving a lattice mismatch minimum. The InN films exhibited a clear sixfold rotational symmetry, without 30 rotational domains and with a full width at half maximum value of the InN 0002 rocking curve being 17.5 arcmin. Comparison between InN films grown on MgAl{sub 2}O{sub 4} and those on (Mn,Zn)Fe{sub 2}O{sub 4} led us to conclude that suppression of the interfacial reactions between the InN films and the substrate is inherently important to obtain high quality InN on substrates with a spinel structure.

  19. Effects of film polarities on InN growth by molecular-beam epitaxy

    Xu, K.; Yoshikawa, A.

    2003-01-01

    Effects of the film polarity on InN growth were investigated in molecular-beam epitaxy (MBE). It was found that N-polarity InN could be grown at higher temperatures than In-polarity one. For the In-polarity films, which were grown on Ga-polar GaN template, the highest growth temperature was limited below 500 deg. C, and the surface morphology and crystal quality tended to be poor mainly because of the tolerated low growth temperature. While for the N-polarity InN films, which were grown on MBE-grown N-polar GaN, the growth temperature could be as high as 600 deg. C. The step-flow-like growth morphology was achieved for the InN films grown with N polarity at 580 deg. C. The resulting full widths of half maximum of x-ray rocking curve around InN (002) and (102) reflections were about 200-250 and 950-1100 arc sec, respectively. The photoluminescence of the InN films peaked at 0.697 eV. The recording Hall mobility of InN film grown in N polarity is 1400 cm 2 /V s with a background carrier concentration of 1.56x10 18 cm -3 at room temperature. For both-polarity films, we found N-rich condition was necessary for the stable InN growth

    2009-01-01

    In this paper, InN thin films were deposited on Si (1 0 0) and K9 glass by reactive direct current magnetron sputtering. The target was In metal with the purity of 99.999% and the gases were Ar (99.999%) and N 2 (99.999%). The properties of InN thin films were studied. Scanning electron microscopy (SEM) shows that the film surface is very rough and energy dispersive X-ray spectroscopy (EDX) shows that the film contains In, N and very little O. X-ray diffraction (XRD) and Raman scattering reveal that the film mainly contains hexagonal InN. The four-probe measurement shows that InN film is conductive. The transmission measurement demonstrates that the transmission of InN deposited on K9 glass is as low as 0.5% from 400 nm to 800 nm.

    The magneto-transport measurements, carried out at magnetic fields up to 11 T and in the temperature range between 1.8 K and 300 K, are used to investigate the scattering mechanisms in GaN/InN/AlN double heterojunctions. Theoretical modeling is based on a variational approach to solving Boltzmann transport equation. It is found that dislocation scattering is the dominant scattering mechanisms at low temperatures because of the large lattice mismatch with the substrate and hence the high density of dislocations in these material systems. Nevertheless, InN epilayers are characterized by a high background carrier density, probably associated with unwanted impurities. Therefore, we also included in our calculations the ionized impurity scattering. However, the effect of ionized impurity scattering as well as the acoustic phonon scattering, remote- background-ionized impurity scattering, and interface roughness scattering on electron mobility are much smaller than that of dislocation scattering. The dislocation densities, in samples with InN thicknesses of 0.4, 0.6 and 0.8 {mu}m, are then determined from the best fit to the experimental data for the low-temperature transport mobility (copyright 2012 WILEY-VCH Verlag GmbH and Co.

    2008-01-01

    We grow InN epilayers on different interlayers by metal organic vapour phase epitaxy (MOVPE) method, and investigate the effect of interlayer on the properties and growth mode of InN films. Three InN samples were deposited on nitrided sapphire, low-temperature InN (LT-InN) and high-temperature GaN (HT-GaN), respectively. The InN layer grown directly on nitrided sapphire owns the narrowest x-ray diffraction rocking curve (XRC) width of 300 arcsec among the three samples, and demonstrates a two-dimensional (2D) step-flow-like lateral growth mode, which is much different from the three-dimensional (3D) pillar-like growth mode of LT-InN and HT-GaN buffered samples. It seems that mismatch tensile strain is helpful for the lateral epitaxy of InN film, whereas compressive strain promotes the vertical growth of InN films

    2017-01-01

    Child contact is a recognised risk factor for adult pneumococcal disease. Peaks in invasive pneumococcal disease incidence observed during winter holidays may be related to changes in social dynamics. This analysis was conducted to examine adult pneumococcal community-acquired pneumonia (CAP) incidence during school holiday periods. Between September 2008 and 2013, consecutive adults admitted to hospitals covering the Greater Nottingham area with a diagnosis of CAP were studied. Pneumococcal pneumonia was detected using culture and antigen detection methods. Of 2221 adults studied, 575 (25.9%) were admitted during school holidays and 643 (29.0%) had pneumococcal CAP. CAP of pneumococcal aetiology was significantly more likely in adults admitted during school holidays compared to term time (35.3% versus 26.7%; adjusted OR 1.38, 95% CI 1.11–1.72, p=0.004). Over the 5-year period, the age-adjusted incidence of hospitalised pneumococcal CAP was higher during school holidays compared to term time (incident rate ratio 1.35, 95% CI 1.14–1.60, pholidays compared to term time (42.0% versus 33.7%, OR 1.43, 95% CI 1.00–2.03, p=0.046). Further study of transmission dynamics in relation to these findings and to identify appropriate intervention strategies is warranted. PMID:28326311

  4. Effects of rapid thermal annealing on the optical and electrical properties of InN epilayers

    Shu, G W; Wu, P F; Liu, Y W; Wang, J S; Shen, J L; Lin, T Y; Pong, P J; Chi, G C; Chang, H J; Chen, Y F; Lee, Y C

    2006-01-01

    We studied the optical and electrical properties of InN epilayers with rapid thermal annealing (RTA). The intensity of the photoluminescence (PL) and the carrier mobility were found to increase as the temperature of RTA was increased. We suggest that the formation of compensating acceptors (indium vacancies) after RTA is responsible for the improvement of the quality in InN. The dependence of the PL emission peak on carrier concentration provides a possible method for estimating the carrier concentration in degenerate InN. (letter to the editor)

    Raman and SIMS studies of Mg-doped InN films with a Mg content from N Mg =3.3 x 10 19 to 5.5 x 10 21 cm -3 are reported. Lattice dynamics of hexagonal InN with substitutional impurities and vacancies has been investigated theoretically and calculated Raman spectra were compared with experimental ones. It is concluded that Raman spectroscopy is a good tool for quantitative characterization of Mg-doped InN. (copyright 2008 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim) (orig.)

  6. Transmission dynamics of the 2009 influenza A (H1N1) pandemic in India: the impact of holiday-related school closure.

    Ali, Sheikh Taslim; Kadi, A S; Ferguson, Neil M

    2013-12-01

    The role of social-distancing measures, such as school closures, is a controversial aspect of pandemic mitigation planning. However, the timing of 2009 pandemic provides a natural experiment for evaluating the impact of school closure during holidays on influenza transmission. To quantify the transmission intensity of the influenza A (H1N1) pdm'09 in India, by estimating the time varying reproduction number (Rt) and correlating the temporal changes in the estimates of Rt for different regions of India with the timing of school holidays. We used daily lab-confirmed case reports of influenza A (H1N1) pdm'09 in India (during 17 May'09 to 17 May'10), stratified by regions. We estimated the transmissibility of the pandemic for different regions from these time-series, using Bayesian methods applied to a branching process model of disease spread and correlated the resulting estimates with the timing of school holidays in each region. The North-west region experienced two notable waves, with the peak of the first wave coinciding with the start of a 4 week school holiday (September-October'09). In the southern region the two waves were less clear cut, though again the first peak of the first wave coincided with the start of school holidays--albeit of less than 2 weeks duration (August'09). Our analysis suggests that the school holidays had a significant influence on the epidemiology of the 2009 pandemic in India. We estimate that school holidays reduced the reproduction number by 14-27% in different regions of India, relative to levels seen outside holiday periods. The estimates of the reproduction number obtained (with peak R values below 1.5) are compatible with those reported from other regions of the world. This work reinforces past studies showing the significant impact of school holidays on spread of 2009 pandemic virus, and by inference the role of contact patterns in children on transmission.

  7. The effect of holiday weight gain on body weight.

    Schoeller, Dale A

    2014-07-01

    The topic of holiday weight gain has been a frequent subject of the lay media; however, scientific interest has only been recent. Multiple studies in Western societies have reported average weight gains among adults during the period between mid-November and mid-January that were about 0.5 kg. The range in individual weight changes was large, however, and the already overweight and obese gain more weight than those who are healthy weight. When the average gain across the year was also measured, the holiday weight was the major contributor to annual excess weight gain. Efforts patterned to increase awareness to energy balance and body weight have been shown to be successful at reducing such gain. An exception to holiday weight gain being a major contributor to annual excess gain has been children, in whom summer weight gains have been observed to be the major contributor to average excess weight gain.

    On the eve of this long weekend for jeûne genevois, many of you are already back from your holidays. The Staff Association hopes you are in fine form for your return to work, which, no doubt, will not be easy. During the holidays, the Staff Association representatives, for their part, carried on with the work they had begun. We would like to inform you about this work by simply running through the list of subjects tackled. This information supplements the three previous editorials.

  9. The Impact of Climate on Holiday Destination Choice

    Bigano, A. [Fondazione Eni Enrico Mattei, Milan (Italy); Hamilton, J.M.

[Institute for Environmental Studies, Vrije Universiteit, Amsterdam (Netherlands)

    2006-06-15

    The holiday destination choice is analysed for tourists from 45 countries, representing all continents and all climates. Tourists are deterred by distance, political instability and poverty, and attracted to coasts. Tourists prefer countries with a sunny yet mild climate, shun climates that are too hot or too cold. A country's tourists' aversion for poverty and distance can be predicted by that country's average per capita income. The preferred holiday climate is the same for all tourists, independent of the home climate. However, tourists from hotter climates have more pronounced preferences.

  10. Anomalous phase transition of InN nanowires under high pressure

    2015-01-01

    Uniform InN nanowires were studied under pressures up to 35.5 GPa by using in situ synchrotron radiation x-ray diffraction technique at room temperature. An anomalous phase transition behavior has been discovered. Contrary to the results in the literature, which indicated that InN undergoes a fully reversible phase transition from the wurtzite structure to the rocksalt type structure, the InN nanowires in this study unusually showed a partially irreversible phase transition. The released sample contained the metastable rocksalt phase as well as the starting wurtzite one. The experimental findings of this study also reveal the potentiality of high pressure techniques to synthesize InN nanomaterials with the metastable rocksalt type structure, in addition to the generally obtained zincblende type one.

  11. InN: Fermi level stabilization by low-energy ion bombardment

    Piper, L.F.J.; Veal, T.D.; McConville, C.F.; Lu, H.; Schaff, W.J.

    2006-01-01

    The near-surface electronic properties of InN have been investigated with high-resolution electron-energy loss spectroscopy. Low-energy (∝400 eV) nitrogen ion bombardment followed by low temperature annealing (<300 C) was found to dramatically increase the n-type conductivity of InN, close to the surface. This is explained in terms of the formation of amphoteric defects from the ion bombardment and annealing combined with the band structure of InN. Low-energy ion bombardment and annealing is shown to result in a damage-induced, donor-like defect-profile instead of the expected electron accumulation for InN.

  12. Catalyst-free growth of InN nanorods by metal-organic chemical vapor deposition

    Kim, Min Hwa; Moon, Dae Young; Park, Jinsub; Nanishi, Yasushi; Yi, Gyu-Chul; Yoon, Euijoon

    2012-01-01

    We demonstrated the growth of catalyst-free InN nanostructures including nanorods on (0001) Al 2 O 3 substrates using metal-organic chemical vapor deposition. As the growth time increased, growth rate along c-direction increased superlinearly with decreasing c-plane area fractions and increasing side wall areas. It was also found that desorption from the sidewalls of InN nanostructures during the InN nanorods formation was one of essential key parameters of the growth mechanism. We propose a growth model to explain the InN nanostructure evolution by considering the side wall desorption and re-deposition of indium at top c-plane surfaces.

    Kobayashi, Atsushi; Okubo, Kana; Ohta, Jitsuo; Oshima, Masaharu; Fujioka, Hiroshi

    2012-01-01

    We have found that polarity of epitaxial InN layers has been controlled by choice of a capping material during high-temperature annealing of yttria-stabilized zirconia (YSZ) (111) substrates in air. Angle-resolved X-ray photoelectron spectroscopy has revealed that the amount of segregation of Y atoms to the YSZ surface depended on the capping material of the substrates. In-polar and N-polar InN have been reproducibly grown on Y-segregated and Y-segregation-free YSZ surfaces, respectively. We have also found that the growth of the first monolayer (ML) of N-polar InN proceeds in a step-flow mode which then switches to layer-by-layer mode after the coverage by 1-ML-thick InN.

  14. Two-dimensional electron gas in monolayer InN quantum wells

    Pan, W.; Wang, G. T.; Dimakis, E.; Moustakas, T. D.; Tsui, D. C.

    2014-01-01

    We report in this letter experimental results that confirm the two-dimensional nature of the electron systems in a superlattice structure of 40 InN quantum wells consisting of one monolayer of InN embedded between 10 nm GaN barriers. The electron density and mobility of the two-dimensional electron system (2DES) in these InN quantum wells are 5 × 10 15  cm −2 (or 1.25 × 10 14  cm −2 per InN quantum well, assuming all the quantum wells are connected by diffused indium contacts) and 420 cm 2 /Vs, respectively. Moreover, the diagonal resistance of the 2DES shows virtually no temperature dependence in a wide temperature range, indicating the topological nature of the 2DES

    2012-01-01

    We report the synthesis of colloidal InN nanocrystals (InN-NCs) in organic solution through nanosecond pulsed laser ablation of high pressure chemical vapor deposition-grown InN thin film on GaN/sapphire template substrate. The size, the structural, the optical, and the chemical characteristics of InN-NCs demonstrate that the colloidal InN crystalline nanostructures in ethanol are synthesized with spherical shape within 5.9–25.3, 5.45–34.8, 3.24–36 nm particle-size distributions, increasing the pulse energy value. The colloidal InN-NCs solutions present strong absorption edge tailoring from NIR region to UV region.

  16. Effects of Cp2Mg supply on MOVPE growth behavior of InN

    Sugita, K.; Sasamoto, K.; Hashimoto, A.; Yamamoto, A.

    2011-01-01

    This report shows the effect of Cp 2 Mg supply on MOVPE growth behavior of InN. At low growth temperature (∝600 C), the formation of adducts occurred, which degenerates the crystal quality. With increasing the growth temperature, the adduct formation was suppressed because the decomposition of Cp 2 Mg was enhanced and thus the incorporation of carbon into the film was suppressed. The use of Cp 2 Mg during InN growth increases the growth rate in the lateral direction. Non-doped InN film grown on GaN buffer has an In-face of the top side. On the other hand, the inversion domains seems to be formed in the highly Mg-doped InN. Tilt distribution decreases from 65 to 30 arcmin with the increase of Cp 2 Mg/TMI molar ratio 0 to 0.06. The donor is produced in highly Mg-doped MOVPE-grown InN (Cp 2 Mg/TMI molar ratio > 0.005). Therefore, the effect of Cp 2 Mg supply on MOVPE growth behavior of InN is found to improve a macro-scale crystal quality but also produces the donor (copyright 2011 WILEY-VCH Verlag GmbH and Co.

  3. Observed Holiday Aerosol Reduction and Temperature Cooling over East Asia

    Gong, Daoyi; Wang, Wenshan; Qian, Yun; Bai, Wenbing; Guo, Yuanxi; Mao, Rui

    2014-06-16

    The Spring Festival air pollution in China was investigated using the long-term observations from 2001-2012 over 323 stations. During the Spring Festival with nearly half of urban population leaving the cities for holidays, the particulate matter (PM10) concentration is about 24.5μgm-3 (23%) lower than normal days. Associated with the national-wide burning of firework, the PM10 concentration sharply increases to 123.8μgm-3 at Chinese New Year Day (increment of 35%). Similar to PM10, the SO2 and NO2 decrease from high values in normal days to a holiday minimum with reduction of 23.3% and 30.6%, respectively. The NO2 has no peak in New Year Day because of the different emission source. The night mean and minimum temperature co-vary with PM10. Both nighttime mean and minimum temperature decrease by about 2.1°C during the holidays. And in association with the pollution jump at New Year Day the night temperature simultaneously increase by about 0.89°C. The in-phase co-variations between PM10 and night temperature suggest an overall warming effect of holiday aerosol during winter in China.

  14. The effect of the Thanksgiving Holiday on weight gain

    Dinger Mary K

    2006-11-01

    Full Text Available Abstract Background More people than ever are considered obese and the resulting health problems are evident. These facts highlight the need for identification of critical time periods for weight gain. Therefore the purpose was to assess potential changes that occur in body weight during the Thanksgiving holiday break in college students. Methods 94 college students (23.0 ± 4.6 yrs, 72.1 ± 14.0 kg, 172.6 ± 9.3 cm, 24.0 ± 3.9 kg/m2 reported to the human body composition laboratory at the University of Oklahoma following a 6-hour fast with testing occurring prior to, and immediately following the Thanksgiving holiday break (13 ± 3 days. Body weight (BW was assessed using a balance beam scale while participants were dressed in minimal clothing. Paired t-tests were used to assess changes in BW pre and post Thanksgiving holiday with additional analysis by gender, body mass index (BMI, and class standing (i.e. undergraduate vs. graduate. Results Overall, a significant (P P P 2 group compared to a non significant 0.2 kg gain in the normal group (2. Conclusion These data indicate that participants in our study gained a significant amount of BW (0.5 kg during the Thanksgiving holiday. While an increase in BW of half a kilogram may not be cause for alarm, the increase could have potential long-term health consequences if participants retained this weight gain throughout the college year. Additionally, because the overweight/obese participants gained the greatest amount of BW, this group may be at increased risk for weight gain and further obesity development during the holiday season.

  15. A porous layer: an evidence for the deterioration of MOVPE InN grown at high temperature (∝650 C)

    Sugita, K.; Hashimoto, A.; Yamamoto, A.

    2009-01-01

    This paper indicates an evidence for the deterioration of the MOVPE InN during the growth at high temperature (∝650 C). It is noted that the deterioration occurs near the interface and InN film becomes porous layer during the further growth. The porous layer has high electron density. The rate-limiting process of N-face InN decomposition depends on atomic hydrogen. The atomic hydrogen produced by the decomposition of NH 3 is responsible for the deterioration of InN film. The crystal quality of InN improves with decreasing the porous layer which is important for MOVPE InN. (copyright 2009 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim) (orig.)

  16. Growth of M-plane (10-10)InN on LiAlO2(100) substrate

    Takagi, Yusuke; Muto, Daisuke; Araki, Tsutomu; Nanishi, Yasushi; Yamaguchi, Tomohiro

    2009-01-01

    In this study, we report the growth and characterization of M-plane InN films on LiAlO 2 (100) substrates by radio-frequency plasma assisted molecular beam epitaxy (RF-MBE). InN films were grown at various temperatures and under various V/III ratios on the substrates. Pure M -plane InN films were successfully grown at a high temperature of 450 C and under a slightly In-rich condition, while the incorporation of C-plane phase was observed in M -plane InN films grown at low temperatures of less than 400 C or under a N-rich condition. These indicate that controls of growth temperature and V/III ratio are important for the growth of pure M-plane InN films. The in-plane epitaxial relationships of M -plane InN on LiAlO 2 (100) were[0001] InN //[010] LiAlO 2 and[1-210] InN //[001] LiAlO 2 . A surface electron accumulation layer on the obtained M-plane InN film is also discussed. (copyright 2009 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim) (orig.)

  17. MOVPE of InN films on GaN templates grown on sapphire and silicon(111) substrates

    Jamil, Muhammad; Arif, Ronald A.; Ee, Yik-Khoon; Tong, Hua; Tansu, Nelson; Higgins, John B.

    2008-01-01

    This paper reports the study of MOVPE of InN on GaN templates grown on sapphire and silicon(111) substrates. Thermodynamic analysis of MOVPE of InN performed using NH 3 as nitrogen source and the experimental findings support the droplet-free epitaxial growth of InN under high V/III ratios of input precursors. At a growth pressure of 500 Torr, the optimum growth temperature and V/III ratio of the InN film are 575-650 C and >3 x 10 5 , respectively. The surface RMS roughness of InN film grown GaN/sapphire template is ∝0.3 nm on 2 μm x 2 μm area, while the RMS roughness of the InN film grown on GaN/Si(111) templates is found as ∝0.7 nm. The X-ray diffraction (XRD) measurement reveals the (0002) texture of the InN film on GaN/sapphire template with a FWHM of 281 arcsec of the InN(0002) ω rocking curve. For the film grown on GaN/Si template under identical growth conditions, the XRD measurements show the presence of metallic In, in addition to the (0002) orientation of InN layer.

    Nanishi, Y.; Saito, Y.; Yamaguchi, T.; Hori, M.; Matsuda, F.; Araki, T.; Suzuki, A.; Miyajima, T.

    2003-01-01

    Recent developments on RF-MBE growth of InN and InGaN and their structural and property characterizations are reviewed. For successful growth of high quality InN, (1) nitridation of the sapphire substrates, (2) two-step growth, (3) precise control of V/III ratio and (4) selection of optimum growth temperature are found to be essential. Characterization using XRD, TEM, EXAFS and Raman scattering have clearly demonstrated that InN films have ideal hexagonal wurtzite structure. It is also found that the film has N-polarity. Studies on optimum growth condition dependence on substrate polarity using C and Si face SiC substrates and Ga and N face free-standing GaN substrates are also demonstrated. The result explains why high-quality InN grown by RF-MBE has N-polarity. PL and CL studies on these well-characterized high-quality InN have shown luminescence peaks at approximately 0.75 eV at 77 K. These values, however, change slightly depending on measurement temperatures and probably on the residual carrier concentrations. InGaN with full compositional range are also successfully grown on sapphire substrates and band gap energies of these alloys are also studied using PL and CL. Based on these results, true band gap energies of InN are discussed. This paper also includes latest study on single crystalline InN growth on Si (111) substrates.

  1. SOME RECENT ISSUES REGARDING THE BEHAVIOR OF THE ROMANIAN TOWNSPEOPLE DURING THE WINTER HOLIDAYS

    TOMA ANDREI

    2017-04-01

    Full Text Available This paper aims to present several aspects of the behavior of the Romanian townspeople in the recent years, on the occasion of the winter holidays. I made an indirect research, based on secondary data sources. Many sources I used are from past years. Sometimes, the secondary sources can provide very valuable data at a national level. The most important Romanian holidays are the winter ones (Saint Nicholas, Christmas, New Year's Eve. There are also other winter holidays, but of lesser importance. The Romanians are traditionalists; they cherish the winter holidays and the family. Giving holiday gifts (sweets, clothing, footwear, perfumes, cosmetics, toys to family members and to close relatives is a feature of Romanian townspeople behavior during the main winter holidays. Most Romanian townspeople spend the winter holidays at home or at friends. During the economic crisis, reduction of costs included also the expenses intended for winter holidays. Changes in the behavior of Romanian tourists, due to the economic crisis, included especially the reduction in the number of holidays, the reduction of the duration of the holiday, avoidance of foreign destinations. This paper does not refer to all the aspects of the purchasing behavior or consumption of the Romanians townspeople on the occasion of winter holidays, but only to some aspects.

    We investigated the local atomic structure around In atoms of MBE-grown InN which has a direct bandgap energy of 0.8 eV, using extended X-ray absorption fine structure (EXAFS) oscillation of In K-edge. The signals from the first-nearest neighbor atoms (N) and second-nearest atoms (In) from In atoms were clearly observed and the atomic bond length of In-N and In-In was estimated to be d{sub In-N}=0.215 nm and d{sub In-In}=0.353 nm, respectively. The In-N bond length of d{sub In-In}=0.353 nm was closed to the a-axis lattice constant of a=0.3536 nm, which was determined using X-ray diffraction measurements. The obtained local atomic structure agreed with the calculated ideal structure. We conclude, therefore, that the InN film with a bandgap energy of 0.8 eV has a high structural symmetry in the range of a few A around In atoms. (Abstract Copyright [2002], Wiley Periodicals, Inc.)

  4. Transport and mobility properties of wurtzite InN and GaN

    Yarar, Zeki

    2007-01-01

    The results of an ensemble Monte Carlo model of the electron transport in wurtzite gallium nitride (GaN) and indium nitride (InN) are presented. There is a controversy over the material parameters of InN, therefore the recently reported and the traditionally accepted parameter values for InN are used in simulations and the results are compared. The steady-state and transient electron transport characteristics are analyzed and the valley populations of electrons are determined as a function of electric field. The low-field mobility of electrons is also obtained as a function of temperature and over a wide range of carrier concentrations. It is seen that with the recently published material parameters the peak velocity of carriers in InN increases significantly, while the field at which it is attained decreases. The calculated maximum low field mobility at 300 K in InN with the recent material parameters is about 10000 cm 2 /V s for low carrier concentrations. (copyright 2007 WILEY-VCH Verlag GmbH and Co.

  5. Impact of potassium and water on the electronic properties of InN(0001) surfaces

    Reiss, S.; Eisenhardt, A.; Krischok, S.; Himmerlich, M.

    2014-01-01

    In this work we investigate the interaction of potassium and water with 2 x 2 reconstructed InN(0001) surfaces prepared by plasma-assisted molecular beam epitaxy. The influence of adsorbate-substrate-interaction on surface properties is characterized in-situ by photoelectron spectroscopy. Potassium exposure leads to a strong reduction in the work function Φ to 1.6 eV revealing a charge transfer from the adsorbate to the InN surface. In parallel, a reduction of the surface downward band bending by 0.2 eV and hence a reduced electron accumulation density is observed. While interaction of water with clean InN(0001)-2 x 2 surfaces induces only minor changes in the surface band bending, water adsorption at potassium covered InN(0001) leads to a reversal of the K-induced reduction in surface band bending and a slight increase of Φ to 2.4 eV. These results show that surrounding water modifies the interaction of potassium with InN(0001) surfaces. (copyright 2014 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim) (orig.)

Se estructuraron tres fases metodológicas, el diagnóstico situacional, estudio de mercado y plan turístico. En la primera fase se delimitó el área de estudio; además se efectuó un análisis interno y externo, utilizando matrices de diagnóstico como la evaluación de factores internos y externos, matriz de competidores y matriz de diagnóstico de fortalezas, oportunidades, debilidades y amenazas. En el estudio de mercado se analizaron los componentes de oferta y demanda del hotel, se determinaron algunas fallas en la denominación utilizada, según los criterios para la categorización hotelera manejada por el Ministerio de Turismo. En función del diagnóstico FODA, se generaron estrategias para el posicionamiento y comercialización del hotel. Mediante las encuestas realizadas a los huéspedes se pudo conocer el perfil del visitante que llega al hotel y se elaboró un plan publicitario, en el cual sobresale el logotipo y slogan, tríptico promocional, la promoción en página web y redes sociales. Se establecieron estrategias del mix para minimizar falencias operativas en el hotel. Se concluye que la principal nomenclatura utilizada no concuerda con los parámetros establecidos por el Ministerio de Turismo, por lo que se plantea reestructurar ciertas áreas específicas como la cantidad de habitaciones o cambiar la denominación a hostal.

  7. Extra holiday because of ionising radiation not necessary

    1978-01-01

    The 'regulations for special measures to protect employees working with X-rays and radium radiation' of 21st November 1947, which included a statutory six-week holiday period annually, has now been superceded by 'regulations on special protective measures for work with ionising radiation', issued by the Directorate for Work Inspection on 31st March 1978, effective from 1st May 1978. In addition to removing the requirement for six weeks annual holiday for radiation personnel, routine medical surveillance is only required every third year instead of annually. A number of other changes are mentioned. The basis for these changes is that continuous personnel dosimetry and better knowledge of the effects of ionising radiation allows any necessary measures to be taken on the basis of these. (JIW)

    Singaporeans are known to have high disposable incomes and come from one of the more influential economies in Asia. Singaporeans have a sizeable impact on the world’s tourism industry. Thus, it is not surprising that they are the target of many tourism destination marketing organizations. Influencing this segment bears great international interest. Existing research identifies the many methods new destinations enter the holiday maker’s mind and move along the destination decision making p...

  10. Holiday CO2: Inference from the Salt Lake City data

    Ryoo, J.; Fung, I. Y.; Ehleringer, J. R.; Stephens, B. B.

    2013-12-01

    A network of high-frequency CO2 sensors has been established in Salt Lake City (SLC), Utah (http://co2.utah.edu/), and the annual/monthly pattern of CO2 variability is consistent with a priori estimates of CO2 fluxes (McKain et al., 2012). Here we ask if short-term changes in anthropogenic sources can be detected, and present a case study of Thanksgiving holiday, when traffic and energy use patterns are expected to be different from that during the rest of the month. CO2 mole fraction is much higher during the Thanksgiving holidays than the other days in November 2008 for all 5 sites in SLC, and a similar pattern is found in other years. Taking into account that the wind speed is relatively low in downtown SLC compared to the other SLC sites, the downtown site is further investigated to minimize the meteorological influence on CO2. In order to understand the relative contributions to the high level of CO2 during the Thanksgiving holidays, we carried out a multiple linear regression (MLR) analysis of the rate of CO2 change against various sources. Mobile CO2 sources are assumed to be proportional to local traffic data and residential CO2 sources are assumed to depend exponentially on temperature. Vulcan data were used to specify the other anthropogenic sources (commercial, industrial, nonroad, electricity, aircraft, and cement). The MLR analysis shows that during the Thanksgiving holidays CO2 contributions from residential and commercial CO2 are larger than that during the rest of November, and mobile sources represent only a relatively small contribution. The study demonstrates the feasibility of detecting changes in urban source contributions using high-frequency measurements in combination with daily PBL height and local traffic volume data.

  12. Stress, Immune Function and Collegiate Holiday Drinking: A Pilot Study.

    Ceballos, Natalie A; Sharma, Shobhit; Patterson, Thomas L; Graham, Reiko; Howard, Krista

    2015-01-01

    Social aspects of collegiate holiday drinking have been studied frequently, but physiological consequences are often overlooked. This study examined self-reported stress, endocrine and immune indicators in students at an American university before and after their week-long spring break (SB) holiday. Participants (n = 27; 9 males) provided saliva samples and completed surveys pre- and post-SB. Based on their cortisol reaction to SB, participants were grouped as cortisol nonresponders (CNR; n = 14) or increasers (CI; n = 13). Groups were matched on demographics, baseline alcohol use, family history of alcoholism, and SB plans. Differences over time and between groups were examined for α-amylase, quantity/frequency of alcohol use (quantity/frequency index, QFI) and the immunoglobulin A (IgA) to albumin ratio (IgA:albumin). α-Amylase decreased over time. A time × group interaction was noted for QFI, in which CNRs increased drinking over SB, but CIs did not. Time and time × group effects occurred for IgA:albumin. CIs decreased IgA:albumin over SB, whereas CNRs did not. Pre-SB QFI and pre-/post-SB QFI changes were correlated with changes in IgA:albumin. These findings support previously published relationships between blunted cortisol responses and risk for problem drinking, as well as elevated cortisol and decreased immune response. These data also highlight the importance of physiological measures in the study of collegiate holiday drinking. © 2015 S. Karger AG, Basel.

  13. Growth of cubic InN on r-plane sapphire

    Cimalla, V.; Pezoldt, J.; Ecke, G.; Kosiba, R.; Ambacher, O.; Spiess, L.; Teichert, G.; Lu, H.; Schaff, W.J.

    2003-01-01

    InN has been grown directly on r-plane sapphire substrates by plasma-enhanced molecular-beam epitaxy. X-ray diffraction investigations have shown that the InN layers consist of a predominant zinc blende (cubic) structure along with a fraction of the wurtzite (hexagonal) phase which content increases with proceeding growth. The lattice constant for zinc blende InN was found to be a=4.986 A. For this unusual growth of a metastable cubic phase on a noncubic substrate an epitaxial relationship was proposed where the metastable zinc blende phase grows directly on the r-plane sapphire while the wurtzite phase arises as the special case of twinning in the cubic structure

  14. Inhomogeneous free-electron distribution in InN nanowires: Photoluminescence excitation experiments

    Segura-Ruiz, J.; Molina-Sánchez, A.; Garro, N.; García-Cristóbal, A.; Cantarero, A.; Iikawa, F.; Denker, C.; Malindretos, J.; Rizzi, A.

    2010-09-01

    Photoluminescence excitation (PLE) spectra have been measured for a set of self-assembled InN nanowires (NWs) and a high-crystalline quality InN layer grown by molecular-beam epitaxy. The PLE experimental lineshapes have been reproduced by a self-consistent calculation of the absorption in a cylindrical InN NW. The differences in the PLE spectra can be accounted for the inhomogeneous electron distribution within the NWs caused by a bulk donor concentration (ND+) and a two-dimensional density of ionized surface states (Nss+) . For NW radii larger than 30 nm, ND+ and Nss+ modify the absorption edge and the lineshape, respectively, and can be determined from the comparison with the experimental data.

  15. LDA+U and tight-binding electronic structure of InN nanowires

    Molina-Sánchez, A.; García-Cristóbal, A.; Cantarero, A.; Terentjevs, A.; Cicero, G.

    2010-10-01

    In this paper we employ a combined ab initio and tight-binding approach to obtain the electronic and optical properties of hydrogenated Indium nitride (InN) nanowires. We first discuss InN band structure for the wurtzite structure calculated at the LDA+U level and use this information to extract the parameters needed for an empirical tight-binging implementation. These parameters are then employed to calculate the electronic and optical properties of InN nanowires in a diameter range that would not be affordable by ab initio techniques. The reliability of the large nanowires results is assessed by explicitly comparing the electronic structure of a small diameter wire studied both at LDA+U and tight-binding level.

  16. Spectral dependence of third-order nonlinear optical properties in InN

    Ahn, H.; Lee, M.-T.; Chang, Y.-M.

    2014-01-01

    We report on the nonlinear optical properties of InN measured in a wide near-infrared spectral range with the femtosecond Z-scan technique. The above-bandgap nonlinear absorption in InN is found to originate from the saturation of absorption by the band-state-filling and its cross-section increases drastically near the bandgap energy. With below-bandgap excitation, the nonlinear absorption undergoes a transition from saturation absorption (SA) to reverse-SA (RSA), attributed to the competition between SA of band-tail states and two-photon-related RSA. The measured large nonlinear refractive index of the order of 10 −10 cm 2 /W indicates InN as a potential material for all-optical switching and related applications

  17. A control technique of oxygen contamination by Ga beam irradiation in InN MOMBE growth

    Isamoto, K.; Uesaka, Y.; Yamamoto, A.; Hashimoto, A.

    2006-01-01

    We have investigated about a control technique of oxygen contamination into the InN layers by simultaneous irradiation of Ga beam during RF-MOMBE growth using the combination of the TMIn and the RF-plasma nitrogen sources. Red shifts of the band gap energy and the improvement of the electrical properties have been achieved by the Ga beam irradiation. The suppression mechanism of the oxygen contamination has been discussed from the experimental results of the InN growth by the RF-MOMBE with the Ga beam irradiation. The present results strongly indicate that the simultaneous irradiation of the Ga beam would be useful to suppress the oxygen contamination into the InN layers during the growth.

  18. Anomalous magnetism of superconducting Mg-doped InN film

    P. H. Chang

    2016-02-01

    Full Text Available We report on the Meissner effect of Mg-doped InN film with superconducting transition onset temperature Tc,onset of 5 K. Mg-doped InN is magnetically ordered and exhibits a simultaneous first-order magnetic and electric transition near 50 K. Its behavior is similar to that of iron-based superconductors. A strong correlation is proposed to exist between structural distortion and superconductivity when Mg is doped into InN. The suppression of magnetic ordering close to Tc by doping is further demonstrated by anisotropic magnetoresistance and M-H measurements. The findings suggest that the superconducting mechanism in the system may not be conventional BCS.

    2006-01-01

    The experimental study of InN and In-rich InGaN by a number of structural, optical and electrical methods is reviewed. Recent advances in thin film growth have produced single crystal epitaxial layers of InN which are similar in structural quality to GaN films made under similar conditions and which can have electron concentrations below 1 x 10 18 cm -3 and mobilities exceeding 2000 cm 2 (Vs) -1 . Optical absorption, photoluminescence, photo-modulated reflectance and soft x-ray spectroscopy measurements were used to establish that the room temperature band gap of InN is 0.67 ± 0.05 eV. Experimental measurements of the electron effective mass in InN are presented and interpreted in terms of a non-parabolic conduction band caused by the k · p interaction across the narrow gap. Energetic particle irradiation is shown to be an effective method to control the electron concentration, n, in undoped InN. Optical studies of irradiated InN reveal a large Burstein-Moss shift of the absorption edge with increasing n. Fundamental studies of the energy levels of defects in InN and of electron transport are also reviewed. Finally, the current experimental evidence for p-type activity in Mg-doped InN is evaluated.

    The influence of high energy (6 MeV, fluencies 10 15 – 10 18 cm -2 ) electron irradiation on the fundamental absorption and luminescence properties of InN thin films which were grown on sapphire substrates by molecular bean epitaxial has been studied. It is found that electron irradiation increases the electron concentration and band gap energy E g of InN. The shift of the band gap energy E g is a manifestation of the Burshtein-Mossa effect.

    2010-01-01

    The temperature dependence of InN growth on (0001) sapphire substrates by atmospheric pressure hydride vapor phase epitaxy (HVPE) was investigated. N-polarity single-crystal InN layers were successfully grown at temperatures ranging from 400 to 500 C. The a and c lattice constants of InN layers grown at 450 C or below were slightly larger than those of InN layers grown above 450 C due to oxygen incorporation that also increased the carrier concentration. The optical absorption edge of the InN layer decreased from above 2.0 to 0.76 eV when the growth temperature was increased from 450 to 500 C. (copyright 2010 WILEY-VCH Verlag GmbH and Co.

  3. Drug Holidays From ADHD Medication: International Experience Over the Past Four Decades.

    Ibrahim, Kinda; Donyai, Parastou

    2015-07-01

    ADHD is managed by stimulants that are effective but can cause growth retardation. Prescribers should ideally monitor children and trial a "drug holiday" to enable catch-up growth. Our aim was to map the experience of drug holidays from ADHD medication in children and adolescents. A comprehensive search of the literature identified 22 studies published during the period 1972 to 2013. Drug holidays are prevalent in 25% to 70% of families and are more likely to be exercised during school holidays. They test whether medication is still needed and are also considered for managing medication side effects and drug tolerance. The impact of drug holidays was reported in terms of side effects and ADHD symptoms. There was evidence of a positive impact on child growth with longer breaks from medication, and shorter breaks could reduce insomnia and improve appetite. Drug holidays from ADHD medication could be a useful tool with multiple purposes: assessment, management, prevention, and negotiation. © 2014 SAGE Publications.

  4. Optical properties of InN nanocolumns: Electron accumulation at InN non-polar surfaces and dependence on the growth conditions

    InN nanocolumns grown by plasma-assisted molecular beam epitaxy have been studied by photoluminescence (PL) and photoluminescence excitation (PLE). The PL peak energy was red-shifted with respect to the PLE onset and both energies were higher than the low temperature band-gap reported for InN. PL and PLE experiments for different excitation and detection energies indicated that the PL peaks were homogeneously broadened. This overall phenomenology has been attributed to the effects of an electron accumulation layer present at the non-polar surfaces of the InN nanocolumns. Variations in the growth conditions modify the edge of the PLE spectra and the PL peak energies evidencing that the density of free electrons can be somehow controlled by the growth parameters. It was observed that In-BEP and substrate temperature leading to shorter In diffusion lengths diminished the effects of the electron accumulation layer on the optical properties.

  6. An Overview of the Geological and Geotechnical Aspects of the New Railway Line in the Lower Inn Valley

    Eder, Stefan; Poscher, Gerhard; Sedlacek, Christoph

    The new railway line in the lower Inn-valley is part of the Brenner railway axis from Munich to Verona (feeder north). The first section between the villages of Kundl and Radfeld, west of Wörgl, and the village of Baumkirchen, east of Innsbruck, will become one of the biggest infrastructure projects ever built in Austria, with a length of approx. 43 km and an underground portion of approx. 80%. The article gives an overview of the various geologic formations - hard rock sections in the valley slopes, different water-saturated gravel and sand formations in the valley floor and geotechnically difficult conditions in sediments of Quaternary terraces. It also describes the methodology of the soil reconnaissance using groundwater models for hydrogeologic estimations, core drillings for evaluating geologic models and describes the experiences gained from the five approx. 7.5 km long reconnaissance tunnels for geotechnical and hydrogeological testing. The results of the soil reconnaissance were used to plan different construction methods, such as excavation in soft rock under a jet grouting roof and compressed-air, as well as mechanised shield with fluid support.

    Some cardiac transplant programs may upgrade listed patients to United Network for Organ Sharing (UNOS) 1A-status during the holidays. Whether more transplants actually occur during holidays is unknown. We assessed rates of single-organ heart transplantation from 2001 to 2010 for recipients age ≥18 yr using the UNOS database. Patients were stratified by transplantation during holiday (±3 d, n = 2375) and non-holiday periods (n = 16 112). Holidays included Easter/Spring break, Memorial Day, July 4th, Labor Day, Thanksgiving, and Christmas/New Years (winter holidays). Secondary analysis assessing transplant rates across seasons was also completed. Donor and recipient characteristics were similar between groups. Compared with non-holidays, July 4th had higher transplant rates (5.69 vs. 5.09 transplants/d, p = 0.03) while the winter holiday had lower transplant rates (4.50 vs. 5.09 transplants/d, p < 0.01). There was a trend toward lower transplant rates for all holidays compared with non-holidays (p = 0.06). Transplant rates were significantly different across seasons with greater rates in spring and summer (p < 0.01). Heart transplant rates were higher during the July 4th and lower during the winter holidays. Although there was a higher likelihood of transplantation during the spring and summer seasons, upgrading patients to 1A status during most holidays may not improve their chances for transplantation. © 2014 John Wiley & Sons A/S.

    Graphical abstract: The morphology evolution of InN nanorods in samples (g)–(i). The alignment of InN nanorods is improved and the deviation angle distribution narrows down with increase in nitriding time. It suggests that extending the nitriding time can enhance the vertical orientation of InN nanorods. - Highlights: • InN nanorods were grown on surface nitrided Si(1 1 1) substrate using PAMBE system. • Nitridation of substrate surface has a strong effect on morphology of InN nanorods. • InN nanorods cannot be formed with 1 min nitridation of Si(1 1 1) substrate. • Increasing nitriding time will increase optimum growth temperature of InN nanorods. • Increasing nitriding time can enhance vertical orientation of InN nanorods. - Abstract: The InN nanorods were grown on Si(1 1 1) substrate by plasma-assisted molecular beam epitaxy (PAMBE) system, with a substrate nitridation process. The effect of nitriding time of Si(1 1 1) substrate on morphology, orientation and growth temperature of InN nanorods was characterized via scanning electron microscopy (SEM) and X-ray diffraction (XRD). The deviation angle of InN nanorods was measured to evaluate the alignment of arrays. The results showed that InN nanorods could not be formed with 1 min nitridation of Si(1 1 1) substrate, but they could be obtained again when the nitriding time was increased to more than 10 min. In order to get aligned InN nanorods, the growth temperature needed to increase with longer nitriding time. The vertical orientation of InN nanorods could be enhanced with increase in nitriding time. The influence of the substrate nitridation on the photoluminescence (PL) spectra of InN nanorods has been investigated.

  9. Observed holiday aerosol reduction and temperature cooling over East Asia

    2014-06-01

    The air pollution in Chinese Spring Festival (CSF) period over eastern China was investigated using the long-term observations from 2001 to 2012 over 323 stations. The dominant feature of the pollutants around the CSF holidays is the significant reduction of concentration. During the 10day period around the CSF (but excluding the Lunar New Year's Day, LNYD), PM10 experiences a reduction of -9.24%. In association with the aerosol reduction, temperature significantly drops over eastern China. From the third day before the LNYD to the second day after, the daily mean temperature anomaly is -0.81°C, and for no-rain days the anomaly is -0.85°C. The simultaneous anomalies of the daily maximum and minimum temperatures are -0.79°C and -0.82°C, respectively. From the third day to seventh day after the LNYD, the significant negative temperature anomalies move out of China, extending to a broad area from the South China Sea to the western North Pacific. Between the 8th and the 12th days, the significant temperature anomalies can still be found over 140°E-160°E and 15°N-25°N. The reduced downward longwave flux might play an important role in holiday cooling. The possible atmospheric feedback is discernable. The thermal and circulation configuration accompanying the cooling favors baroclinic interaction between upper and lower troposphere for the midlatitude cyclone. The anomalous cyclone becomes mature during the third to the seventh day after the LNYD and disappears 12 days later. The anomalous northern winds in association with the cyclone decrease the temperature and also help disperse the holiday aerosols over eastern China.

  10. Epidemiology of pediatric holiday-related injuries presenting to US emergency departments.

    2010-05-01

    The objective of this study was to calculate injury rates and describe the epidemiology of holiday-related injuries among children who were aged holiday-related injuries obtained from the US Consumer Product Safety Commission's National Electronic Injury Surveillance System were analyzed. From 1997 through 2006, an estimated 5,710,999 holiday-related injuries sustained by children who were aged holidays were classified as sports and recreation-related. In addition, home structure-related and home furnishing-related injuries were prevalent. Injuries that were associated with fireworks were more likely to occur on the Fourth of July than any other holiday, yet fireworks accounted for only a small proportion of Fourth of July injuries. Most injuries that were sustained on holidays and required ED treatment were not holiday-specific but were associated with more general activities. Parents should be aware that holidays present a risk not only for holiday-specific injuries but also for more general, "everyday" injuries.

  14. Polarity and microstructure in InN thin layers grown by MOVPE

    Kuwano, N.; Nakahara, Y.; Amano, H.

    2006-01-01

    Microstructures in InN grown on sapphire (0001) and yttria-stabilized zirconia (YSZ) (111) by metal-organic vapor phase epitaxy (MOVPE) were analyzed by means of transmission electron microscopy (TEM) in order to clarify the growth process. Special attention was paid to the selectivity of the crystal polarity of InN. The InN thin films grown on sapphire after nitridation has a flat surface while those grown on YSZ has hillocks on the surface. The crystal polarity was determined by comparing the experimentally observed intensity distribution in convergent beam electron diffraction (CBED) disks with those simulated by the Broch-wave method. It was found that the InN grown on the sapphire has a nitrogen-polarity and the one on YSZ has a mixture of In- and N-polarities. The effect of surface-nitridation of sapphire on the growth process is also discussed (copyright 2006 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim) (orig.)

    2007-01-01

    The in-plane lattice parameters of InN, GaN and Al 2 O 3 in a InN/GaN/Al 2 O 3 (0001) heterostructure have been measured as a function of temperature in the range of 25-350 C, using high resolution X-ray diffraction. The results reveal that both the GaN and InN crystals follow the in-plane thermal expansion of the Al 2 O 3 substrate's lattice and there is no rearrangement of misfit dislocations at the InN/GaN and GaN/Al 2 O 3 interfaces. It was also found that either compressive or tensile character of residual biaxial strain is possible for the InN films, depending on the two-dimensional (2D) or three-dimensional (3D) growth mode of InN on the GaN(0001) buffer layer. The tensile strain is inherent to the nucleation and coalescence of 3D islands. (copyright 2007 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim) (orig.)

  16. Theoretical Investigation on Structural and Electronic Properties of InN Growth on Ce-Stabilized Zirconia (111 Substrates

    2016-01-01

    Full Text Available The structural and electronic properties of InN on Ce-stabilized zirconia (CeSZ (111 substrates are investigated using first-principles calculations based on density functional theory with GGA + U method. Surface energy calculations indicate that the structure of Ce-segregated surface is more energetically stable than that of Ce-segregation-free surface. Adsorption energies of indium and nitrogen atoms on both Ce-segregated and Ce-segregation-free CeSZ (111 surfaces at the initial growth stage have been studied. The results suggest that the first layer of InN films consists of a nitrogen layer, which leads to epitaxial relationships between InN (0001 // CeSZ (111 and InN [112¯0] // CeSZ [11¯0]. In addition, density of states (DOS analysis revealed that the hybridization effect plays a crucial role in determining the interface structure for the growth of InN on CeSZ (111 surfaces. Furthermore, adsorption energies of indium atoms on the nitrogen layer have also been evaluated in order to investigate the lattice polarity determination for InN films. It was found that an indium atom preferentially adsorbs at the center of three nitrogen atoms stacked on the CeSZ substrate, which results in the formation of In-polarity InN.

    We report the unusual photoluminescence (PL) properties of vertically aligned InN nanorod arrays grown on Si(111) with a Si 3 N 4 buffer layer. The optimum growth conditions of InN nanorods are obtained by controlling the III/V ratio and the growth temperature. Structural characterization by X-ray diffraction and scanning electron microscopy indicates that individual nanorods are wurtzite InN single crystals with the growth direction along the c-axis. Near-infrared PL from InN nanorods is clearly observed at room temperature. However, in comparison to the PL from InN epitaxial films, the PL from InN nanorods is significantly lower in efficiency and exhibit anomalous temperature dependence. We propose that these unusual PL properties are results of considerable structural disorder (especially for the low-temperature grown InN nanorods) and strong surface electron accumulation effect.

    A series of InN thin films was grown on sapphire substrates via plasma-assisted molecular beam epitaxy (PA-MBE) with different nitrogen plasma power. Various characterization techniques, including Hall, photoluminescence, Raman scattering and Rutherford backscattering, have been employed to study these InN films. Good crystalline wurtzite structures have been identified for all PA-MBE grown InN films on sapphire substrate, which have narrower XRD wurtzite (0002) peaks, showed c-axis Raman scattering allowed longitudinal optical (LO) modes of A 1 and E 1 plus E 2 symmetry, and very weak backscattering forbidden transverse optical (TO) modes. The lower plasma power can lead to the lower carrier concentration, to have the InN film close to intrinsic material with the PL emission below 0.70 eV. With increasing the plasma power, high carrier concentration beyond 1 x 10 20 cm -3 can be obtained, keeping good crystalline perfection. Rutherford backscattering confirmed most of InN films keeping stoichiometrical In/N ratios and only with higher plasma power of 400 W leaded to obvious surface effect and interdiffusion between the substrate and InN film.

    Graphical abstract: Display Omitted Highlights: ► A novel growth method to form InN at low growth temperatures. ► Use of Si reconstruction as a growth template for group III nitrides. ► Band gap variation of InN – Moss–Burstein shift – non-parabolic conduction band for InN. ► Super lattice matching epitaxy of metal induced reconstructions with III–V unit cell. -- Abstract: Indium induced surface reconstructions of Si(1 1 1)-7 × 7 are used as templates to grow high quality InN. We grow InN on Si(1 1 1)-7 × 7, Si(1 1 1)-4 × 1-In and Si(1 1 1)-1 × 1-In reconstructed surfaces and study the quality of the films formed using complementary characterization tools. InN grown on Si(1 1 1)-1 × 1-In reconstruction shows superior film quality with lowest band-edge emission having a narrow full width at half maximum, intense and narrow 0 0 0 2 X-ray diffraction, low surface roughness and carrier concentration an order lower than other samples. We attribute the high quality of the film formed at 300 °C to the integral matching of InN and super lattice dimensions, we also study the reasons for the band gap variation of InN in the literature. Present study demonstrates the proposed Superlattice Matched Epitaxy can be a general approach to grow good quality InN at much lower growth temperature on compatible In induced reconstructions of the Si surface.

    InN/ZnO:Al heterostructures deposited at low temperature on different substrates by radio-frequency sputtering were studied. Using ZnO:Al as buffer layer, an improvement in the InN structural properties was achieved. Evaluating ZnO:Al as contact on InN, an Ohmic behaviour for the as-deposited layer on InN was achieved. A specific contact resistance of 2 {omega} cm{sup 2} was measured without any post-deposition treatment. These properties could result very promising for optoelectronic device applications.

    We compared the local structure around In atoms in microwave-excited MOCVD- and MBE-grown InN film which indicates an absorption edge at 1.9 and 0.8 eV, respectively. The co-ordination numbers of the 1st-nearest neighbor N atoms and the 2nd-nearest neighbor In atoms for MBE-grown InN were n(N)=3.9{+-}0.5 and n(In)=12.4{+-}0.9, which are close to the ideal value of n(N)=4 and n(In)=12 for InN without defects, respectively. By thermal annealing, the structure of MBE-grown InN was changed from InN to In{sub 2}O{sub 3}, and the absorption edge was changed from 0.8 to 3.5 eV. However, the microwave-excited MOCVD-grown InN had no structure of In{sub 2}O{sub 3}, and had the reduced co-ordination numbers of the 2nd-nearest neighbor In atoms of n(In)=10.6-11.7. From these results, we conclude that the origin of the 1.9-eV absorption edge of InN is the imperfections (defects) of the In lattice sites of InN, rather than the generation of In{sub 2}O{sub 3}, which has a bandgap energy of 3.5 eV.

  12. One week's holiday sun exposure induces expression of photoaging biomarkers.

    Lesiak, Aleksandra; Rogowski-Tylman, Michal; Danilewicz, Marian; Wozniacka, Anna; Narbutt, Joanna

    2016-01-01

    Skin aging is accompanied by the upregulation of the expression of various matrix metalloproteinases (MMPs). It was shown that exposure to ultraviolet radiation (UVR) may induce skin expression of MMPs and dysregulation of the transforming growth factor beta (TGF-β)/Smad pathway. The aim of our study was to compare the effects of short holiday UVR exposure and lifetime UVR exposure, on the expression of MMP-8, TGF-β1, and Smad2 in human skin biopsies. Skin biopsies were taken from the outer upper arm of 15 elderly people with significant photoaging (mean age 64.1 years) (Group 1) and from 15 healthy young adult volunteers (mean age 24.1 y) who participated in a six-day sun holiday. Biopsies were taken twice: 24 hours before leaving for holiday (Group 2a) and 24 hours after returning (Group 2b). The expression of TGF-β1, Smad2, and MMP-8 was examined by immunochemistry and measured semiquantitatively by two independent pathologists. The mean expression of TGF-β1 in dermal fibroblasts and keratinocytes in Group 1 and Group 2b was significantly lower than in Group 2a (0.54% ± 0.44% and 0.48% ± 0.51% vs. 1.48% ± 0.72%, respectively). The percentage of Smad2 (+) cells in Group 1 and Group 2b was lower than in Group 2a (2.13% ± 1.39% and 1.81% ± 1.16% vs. 4.13% ± 1.58%, respectively). The MMP-8 expression in Group 2b was 1.36% ± 0.68% and was significantly higher than in Group 1 (0.34% ± 0.42%) and Group 2a in which the protein was not detected (p < 0.001). We conclude that the decrease in the expression of TGF-β1 and Smad2 is a persistent biomarker of skin photoaging, while the increased expression of MMP-8 in keratinocytes can be regarded as a marker of acute sun exposure.

  13. High-phase-purity zinc-blende InN on r-plane sapphire substrate with controlled nitridation pretreatment

    Hsiao, C.-L.; Wu, C.-T.; Hsu, H.-C.; Hsu, G.-M.; Chen, L.-C.; Liu, T.-W.; Shiao, W.-Y.; Yang, C. C.; Gaellstroem, Andreas; Holtz, Per-Olof; Chen, C.-C.; Chen, K.-H.

    2008-01-01

    High-phase-purity zinc-blende (zb) InN thin film has been grown by plasma-assisted molecular-beam epitaxy on r-plane sapphire substrate pretreated with nitridation. X-ray diffraction analysis shows that the phase of the InN films changes from wurtzite (w) InN to a mixture of w-InN and zb-InN, to zb-InN with increasing nitridation time. High-resolution transmission electron microscopy reveals an ultrathin crystallized interlayer produced by substrate nitridation, which plays an important role in controlling the InN phase. Photoluminescence emission of zb-InN measured at 20 K shows a peak at a very low energy, 0.636 eV, and an absorption edge at ∼0.62 eV is observed at 2 K, which is the lowest bandgap reported to date among the III-nitride semiconductors

  14. The paradox of public holidays: Hospital-treated self-harm and associated factors.

    Griffin, Eve; Dillon, Christina B; O'Regan, Grace; Corcoran, Paul; Perry, Ivan J; Arensman, Ella

    2017-08-15

    Recent research on the patterns of self-harm around public holidays is lacking. This study used national data to examine the patterns of hospital-treated self-harm during public holidays, and to examine associated factors. Data on self-harm presentations to all emergency departments were obtained from the National Self-Harm Registry Ireland. The association between self-harm presentations and public holidays was examined using univariate and multivariate Poisson regression analyses. A total of 104,371 presentations of self-harm were recorded between 2007 and 2015. The mean number of self-harm presentations was 32 on public holidays. St. Patrick's Day had the highest number of presentations compared to all other public holidays, with a daily mean of 44 presentations. Across all years, self-harm presentations during public holidays had a 24% increased risk of involving alcohol consumption compared to all other days and this effect was most pronounced during the Christmas period. The association with alcohol remained significant at a multivariate level. Presentations on public holidays were more likely to attend out of normal working hours. An increase in male presentations involving self-cutting was observed on public holidays and there was an over-representation of males presenting for the first time. It is likely that extent of alcohol involvement in self-harm presentations reported here is an underestimate, as it was dependent on the information being recorded by the attending clinician. Public holidays are associated with an elevated number of self-harm presentations to hospital, with presentations to hospital involving alcohol significantly increased on these days. Hospital resources should be targeted to address increases during public holidays, including during out-of-hours. Involvement of alcohol may delay delivery of care to these patients in emergency settings. Copyright © 2017 Elsevier B.V. All rights reserved.

  15. Epitaxial growth of InN on c-plane sapphire by pulsed laser deposition with r.f. nitrogen radical source

    Ohta, J.; Fujioka, H.; Honke, T.; Oshima, M.

    2004-01-01

    We have grown InN films on c-plane sapphire substrates by pulsed laser deposition (PLD) with a radio frequency nitrogen radical source for the first time and investigated the effect of the substrate surface nitridation on the structural and electrical properties of InN films with reflection high energy electron diffraction (RHEED), atomic force microscope, the Hall effect measurements and high-resolution X-ray diffraction (HRXRD). RHEED and HRXRD characterizations revealed that high-quality InN grows epitaxially on sapphire by PLD and its epitaxial relationship is InN (0 0 0 1) parallel sapphire (0 0 0 1) and InN [2 -1 -1 0] parallel sapphire [1 0 -1 0]. The InN crystalline quality and the electron mobility are improved by the substrate nitridation process. The area of the pits at the InN surface is reduced by the substrate nitridation process probably due to the reduction in the interface energy between InN and the substrate. The full width at half maximum of the -1 -1 2 4 X-ray rocking curve for InN grown by the present technique without using any buffer layers was as small as 34.8 arcmin. These results indicate that the present technique is promising for the growth of the high-quality InN films

  16. Healthcare and a holiday: the risks of LASIK tourism.

    Lockington, David; Johnson, Richard; Patel, Dipika V; McGhee, Charles N J

    2014-07-01

    Medical tourism is the practice of travelling overseas for surgery. We describe a patient with low myopia who underwent laser in situ keratomileusis (LASIK) while on holiday in India. She presented to local hospital eye services six weeks post-LASIK with discomfort and reduced vision. She reported three previous LASIK flap lifts in the right eye. Clinical assessment, optical coherence tomography and confocal microscopy demonstrated moderate epithelial ingrowth and reduced visual acuity. Epithelial ingrowth after LASIK may be associated with visual impairment and management is determined by location, magnitude and effect on vision. LASIK tourism may mean patients are less well-informed of risks and lose continuity of professional care. © 2013 The Authors.

  18. The impact of holiday eating cues on self-regulatory bolstering for dieters and non-dieters.

    Martins, Chrissy M; Vallen, Beth

    2014-01-01

    Two studies examined the hypothesis that the presence vs. absence of holiday food cues leads dieters to bolster self-regulatory resources and reduce consumption of a snack food. Study 1 evaluated snack-food consumption on a holiday vs. a non-holiday and in Study 2, the proposed underlying mechanism--the bolstering of self-regulatory resources when facing holiday-related cues--was explored. Study 1 followed a quasi-experimental design in which participants (N = 152) consumed candies either on a holiday or a non-holiday. Dieting behaviour was measured and the main outcome measure was consumption quantity. In Study 2, a true experiment, participants (N = 110) read primes associated with holiday eating, holiday history or a neutral topic. Self-regulatory bolstering was assessed as the main outcome measure. Study 1 showed that dieters consume more of a food item on an ordinary day relative to a holiday; the consumption patterns of non-dieters did not vary based on holiday cues. Study 2 demonstrated that dieters, but not non-dieters, bolster self-regulatory resources to a greater extent in the presence vs. absence of a holiday food cue. Dieters are better equipped to defend their diet-related goals when facing strong holiday-related temptations than weaker, everyday temptations.

  19. Growth modes of InN (000-1) on GaN buffer layers on sapphire

    Liu Bing; Kitajima, Takeshi; Chen Dongxue; Leone, Stephen R.

    2005-01-01

    In this work, using atomic force microscopy and scanning tunneling microscopy, we study the surface morphologies of epitaxial InN films grown by plasma-assisted molecular beam epitaxy with intervening GaN buffer layers on sapphire substrates. On smooth GaN buffer layers, nucleation and evolution of three-dimensional InN islands at various coverages and growth temperatures are investigated. The shapes of the InN islands are observed to be predominantly mesalike with large flat (000-1) tops, which suggests a possible role of indium as a surfactant. Rough GaN buffer layers composed of dense small GaN islands are found to significantly improve uniform InN wetting of the substrates, on which atomically smooth InN films are obtained that show the characteristics of step-flow growth. Scanning tunneling microscopy imaging reveals the defect-mediated surface morphology of smooth InN films, including surface terminations of screw dislocations and a high density of shallow surface pits with depths less than 0.3 nm. The mechanisms of the three-dimensional island size and shape evolution and formation of defects on smooth surfaces are considered

  20. Crystallinity, Surface Morphology, and Photoelectrochemical Effects in Conical InP and InN Nanowires Grown on Silicon.

    Parameshwaran, Vijay; Xu, Xiaoqing; Clemens, Bruce

    2016-08-24

    The growth conditions of two types of indium-based III-V nanowires, InP and InN, are tailored such that instead of yielding conventional wire-type morphologies, single-crystal conical structures are formed with an enlarged diameter either near the base or near the tip. By using indium droplets as a growth catalyst, combined with an excess indium supply during growth, "ice cream cone" type structures are formed with a nanowire "cone" and an indium-based "ice cream" droplet on top for both InP and InN. Surface polycrystallinity and annihilation of the catalyst tip of the conical InP nanowires are observed when the indium supply is turned off during the growth process. This growth design technique is extended to create single-crystal InN nanowires with the same morphology. Conical InN nanowires with an enlarged base are obtained through the use of an excess combined Au-In growth catalyst. Electrochemical studies of the InP nanowires on silicon demonstrate a reduction photocurrent as a proof of photovolatic behavior and provide insight as to how the observed surface polycrystallinity and the resulting interface affect these device-level properties. Additionally, a photovoltage is induced in both types of conical InN nanowires on silicon, which is not replicated in epitaxial InN thin films.

    2010-09-01

    100 nm InN layer was grown on sapphire c-plane using a metal-organic chemical vapor deposition (MOCVD) system. Low temperature (LT) GaN layer was grown on InN layer to protect InN layer from direct exposure to hydrogen flow during high temperature (HT) GaN growth and/or abrupt decomposition. Subsequently, thick HT GaN layer (2.5 {mu}m thick) was grown at 1000 {sup o}C on LT GaN/InN/sapphire template. Microstructure of epilayer-substrate interface was investigated by transmission electron microscopy (TEM). From the high angle annular dark field TEM image, the growth of columnar structured LT GaN and HT GaN with good crystallinity was observed. Though thickness of InN interlayer is assumed to be about 100 nm based on growth rate, it was not clearly shown in TEM image due to the InN decomposition. The lattice parameters of GaN layers were measured by XRD measurement, which shows that InN interlayer reduces the compressive strain in GaN layer. The relaxation of compressive strain in GaN layer was also confirmed by photoluminescence (PL) measurement. As shown in the PL spectra, red shift of GaN band edge peak was observed, which indicates the reduction of compressive strain in GaN epilayer.

  3. Ab-initio study of Mg-doped InN(0001 surface

    A. Belabbes

    2013-01-01

    Full Text Available We study the incorporation of Mg atoms into the InN(0001 surface. Energies and atomic geometries are described within density functional theory, while the electronic structure is investigated by an approximate quasiparticle method that yields a gap value of 0.7 eV for bulk InN. The formation of substitutional Mg is energetically favored in the surface layer. The surface electronic structure is less influenced by Mg-derived states. The Fermi level is pinned by In-derived surface states. With increasing depth of Mg beneath the surface the Fermi-level position moves toward the valence band top, suggesting formation of holes and, hence, p-doping of Mg in bulk-like layers.

  4. An Analysis of Open-Ended Online Reviews about Bed and Breakfast and Inns in Portugal

    Sara Evans Machado dos Santos

    2014-03-01

    Full Text Available Researches about User-Generated Content (UGC have gained attention in the fields of Tourism and Hospitality in the last years. This study focus on online reviews about alternative accommodations – B&Bs and Inns. The development of this work was realized applying inductive methods and using an exploratory approach. We collected a sample of 450 online reviews and analyzed them segment by segment, making a total of 4621 segments. We used the Appraisal Theory to assess what attitudes online reviewers are expressing about B&Bs and Inns in Lisbon. We verified that positive appreciation is the most frequent attitude while expressions of affect and judgment are more rare. This study contributes to the academy as it brings a new parameter of analysis of UGC using the Appraisal Theory in the field of Hospitality.

  5. Morphology Controlled Fabrication of InN Nanowires on Brass Substrates

    Huijie Li

    2016-10-01

    Full Text Available Growth of semiconductor nanowires on cheap metal substrates could pave the way to the large-scale manufacture of low-cost nanowire-based devices. In this work, we demonstrated that high density InN nanowires can be directly grown on brass substrates by metal-organic chemical vapor deposition. It was found that Zn from the brass substrates is the key factor in the formation of nanowires by restricting the lateral growth of InN. The nanowire morphology is highly dependent on the growth temperature. While at a lower growth temperature, the nanowires and the In droplets have large diameters. At the elevated growth temperature, the lateral sizes of the nanowires and the In droplets are much smaller. Moreover, the nanowire diameter can be controlled in situ by varying the temperature in the growth process. This method is very instructive to the diameter-controlled growth of nanowires of other materials.

    The surface acoustic wave velocity in InN has been experimentally determined by means of Brillouin scattering experiments on c - and m -face epilayers. From simulations based on the Green's function formalism we determine the shear elastic constants c{sub 66} and c{sub 44} and propose a complete set of elastic constants for wurtzite InN. The analysis of the sagittal and azimuthal dependence of the surface acoustic wave velocity indicates a slightly different elastic behavior of the m -face sample that basically affects the c{sub 44} elastic constant.

    Xu, L H R; Adams-Huet, B; Poindexter, J R; Maalouf, N M

    2016-05-01

    In a retrospective analysis of 208 osteoporotic patients followed during a bisphosphonate holiday, lower body weight and risedronate use were associated with a more rapid decline in bone mineral density during the bisphosphonate holiday, while bone mineral density (BMD) trends were similar in patients who sustained vs. did not sustain a fracture. A drug holiday has been suggested for some bisphosphonate-treated patients with osteoporosis to minimize potential side effects from prolonged use. However, there is limited information on the evolution of BMD during a bisphosphonate holiday. Our study analyzed the longitudinal course of BMD following bisphosphonate discontinuation and assessed its determinants. Retrospective single-center cohort study of osteoporosis patients treated with alendronate or risedronate for at least 2 years and then discontinued their bisphosphonate for a drug holiday. Patients were stratified by bisphosphonate type and by fracture occurrence during drug holiday. A total of 208 patients were included in this analysis (87.5 % female). At the time of bisphosphonate cessation, mean ± SD age was 66.9 ± 8.9 years and BMI 24.5 ± 4.4 kg/m(2). Duration of bisphosphonate treatment was 5.2 ± 2.3 years, and follow-up during holiday was 3.3 ± 1.7 years. During the first 2 years of the holiday, BMD remained stable at the lumbar spine and femoral neck, but declined significantly at the total hip. BMD declined significantly at all sites thereafter. Significant predictors of BMD decline during bisphosphonate holiday included lower BMI at the start of the holiday and change in body weight during the holiday. BMD decline was more pronounced in former risedronate compared to former alendronate users. BMD trends were similar in patients who sustained vs. did not sustain a fracture during the holiday. BMD at the total hip declines significantly within 1 year of bisphosphonate discontinuation, particularly in lean patients

    We present a detailed magnetic characterization of Cr and Mn doped InN films be means of superconducting quantum interference device magnetometry and X-ray magnetic circular dichroism. The InN:Cr films exhibit ferromagnetic behavior up to 300 K in a doping region from 2% to 8% without detectable phase segregation. The easy axis of magnetization is found to be in the film plane. On the contrary, Mn-doped films show signatures of phase segregation and paramagnetic behavior

  9. "Could I return to my life?" Integrated Narrative Nursing Model in Education (INNE).

    Artioli, Giovanna; Foà, Chiara; Cosentino, Chiara; Sulla, Francesco; Sollami, Alfonso; Taffurelli, Chiara

    2018-03-28

    The Integrated Narrative Nursing Model (INNM) is an approach that integrates the qualitative methodology typical of the human sciences, with the quantitative methodology more often associated with the natural sciences. This complex model, which combines a focus on narrative with quantitative measures, has recently been effectively applied to the assessment of chronic patients. In this study, the model is applied to the planning phase of education (Integrated Narrative Nursing Education, INNE), and proves to be a valid instrument for the promotion of the current educational paradigm that is centered on the engagement of both the patient and the caregiver in their own path of care. The aim of this study is therefore to describe the nurse's strategy in the planning of an educational intervention by using the INNE model. The case of a 70-year-old woman with pulmonary neoplasm is described at her first admission to Hospice. Each step conducted by the reference nurse, who uses INNE to record the nurse-patient narrative and collect subsequent questionnaires in order to create a shared educational plan, is also described. The information collected was submitted, starting from a grounded methodology to the following four levels of analysis: I. Needs Assessment, II. Narrative Diagnosis, III. Quantitative Outcome, IV. Integrated Outcome. Step IV, which is derived from the integration of all levels of analysis, allows a nurse to define, even graphically, the conceptual map of a patient's needs, resources and perspectives, in a completely tailored manner. The INNE model offers a valid methodological support for the professional who intends to educate the patient through an inter-subjective and engaged pathway, between the professional, their patient and the socio-relational context. It is a matter of adopting a complex vision that combines processes and methods that require a steady scientific basis and advanced methodological expertise with active listening and empathy

  10. Ultrafast Carrier Relaxation in InN Nanowires Grown by Reactive Vapor Transport

    Zervos Matthew

    2008-01-01

    Full Text Available Abstract We have studied femtosecond carrier dynamics in InN nanowires grown by reactive vapor transport. Transient differential absorption measurements have been employed to investigate the relaxation dynamics of photogenerated carriers near and above the optical absorption edge of InN NWs where an interplay of state filling, photoinduced absorption, and band-gap renormalization have been observed. The interface between states filled by free carriers intrinsic to the InN NWs and empty states has been determined to be at 1.35 eV using CW optical transmission measurements. Transient absorption measurements determined the absorption edge at higher energy due to the additional injected photogenerated carriers following femtosecond pulse excitation. The non-degenerate white light pump-probe measurements revealed that relaxation of the photogenerated carriers occurs on a single picosecond timescale which appears to be carrier density dependent. This fast relaxation is attributed to the capture of the photogenerated carriers by defect/surface related states. Furthermore, intensity dependent measurements revealed fast energy transfer from the hot photogenerated carriers to the lattice with the onset of increased temperature occurring at approximately 2 ps after pulse excitation.

  11. PHYSICAL PROPERTIES OF InN PARTICLES OBTAINED BY RF MAGNETRON SPUTTERING

    Roberto Bernal Correa

    2014-01-01

    Full Text Available InN layers were prepared by magnetron sputtering, in a mixed atmosphere of argon and nitrogen on Si substrates (100, Si (111, and glass. The substrate temperature Ts was varied (300-500 oC in order to correlate it with the optical, structural, and morphological properties of the layers. X-ray results have revealed a presence of hexagonal InN type wurtzite in each of the layers in addition to oxides of indium (InxOy attributed to different factors. Dependence was evident on the crystalline quality of each layer according to Ts. The optical absorption coefficient and the band gap were determined from the absorbance and transmittance spectra obtained by UV/Vis. Vibration modes associated with the semiconductor InN and InxOy were identified by Raman microscopy. The morphology of the layers and the grain size was analyzed from SEM micrographs where it was determined the formation of particulates  ~ 0.5 mm and ~ 50 nm of different geometries.

    In this work, we study theoretically and experimentally the influence of the surface electron accumulation on the optical properties of InN nanowires. For this purpose, the photoluminescence and photoluminescence excitation spectra have been measured for a set of self-assembled InN NWs grown under different conditions. The photoluminescence excitation experimental lineshapes have been reproduced by a self-consistent calculation of the absorption in a cylindrical InN nanowires. With the self-consistent model we can explore how the optical absorption depends on nanowires radius and doping concentration. Our model solves the Schroedinger equation for a cylindrical nanowire of infinite length, assuming a parabolic conduction band. The columnar geometry introduces effects in both the electron density and in the self-consistent conduction band profile, with no equivalence in planar layer. On the other hand, the differences in the photoluminescence excitation spectra are related to the inhomogeneous electron distribution inside the nanowires, caused by a bulk donor concentration and a two-dimensional density of ionized surface states. For nanowire radii larger than 30 nm, such concentrations modify the absorption edge and the lineshape, respectively, and can be determined from the comparison with the experimental data (copyright 2012 WILEY-VCH Verlag GmbH and Co.

  13. Effective electron mass and phonon modes in n-type hexagonal InN

    Kasic, A.; Schubert, M.; Saito, Y.; Nanishi, Y.; Wagner, G.

    2002-03-01

    Infrared spectroscopic ellipsometry and micro-Raman scattering are used to study vibrational and electronic properties of high-quality hexagonal InN. The 0.22-μm-thick highly n-conductive InN film was grown on c-plane sapphire by radio-frequency molecular-beam epitaxy. Combining our results from the ellipsometry data analysis with Hall-effect measurements, the isotropically averaged effective electron mass in InN is determined as 0.14m0. The resonantly excited zone center E1 (TO) phonon mode is observed at 477 cm-1 in the ellipsometry spectra. Despite the high electron concentration in the film, a strong Raman mode occurs in the spectral range of the unscreened A1(LO) phonon. Because an extended carrier-depleted region at the sample surface can be excluded from the ellipsometry-model analysis, we assign this mode to the lower branch of the large-wave-vector LO-phonon-plasmon coupled modes arising from nonconserving wave-vector scattering processes. The spectral position of this mode at 590 cm-1 constitutes a lower limit for the unscreened A1(LO) phonon frequency.

  14. Weight and body composition change over a six-week holiday period.

    Wagner, D R; Larson, J N; Wengreen, H

    2012-03-01

    Change in weight and body composition was assessed over a six-week holiday period. Baseline testing occurred the Monday or Tuesday prior to Thanksgiving Day (November 24 or 25, 2008), and the post-holiday assessment was the Monday or Tuesday after New Year's Day (January 5 or 6, 2009). Thirteen men and 21 women ranging in age from 23-61 years completed the study. The majority of participants (24 of 34) perceived that they had gained weight, and four did gain ≥2 kg. However, despite some changes to dietary and exercise habits, on average there was no difference between pre-holiday weight (74.0±17.8 kg) and post-holiday weight (73.9±18.1 kg), nor between pre-holiday body fat percentage (25.4±9.0%) and post-holiday body fat percentage (25.4±8.9%). Despite a perception of substantial weight gain, body weight and body fat remained unchanged over a six-week holiday period.

  15. Observation of a "holiday effect": a case of Chinese New Year in Taipei

    Tan, P.-H.; Chou, C.; Chen, P.-Y.; Liang, J.-Y.

    2009-04-01

    Our study was an attempt to conduct a comprehensive and systematical examination of the holiday effect, defined as the difference in air pollutant concentrations between holiday and non-holiday periods. This holiday effect can be applied to other countries with similar national or cultural holidays. Hourly and daily surface measurements of six major air pollutants from thirteen air quality monitoring stations of the Taiwan Environmental Protection Administration during the Chinese New Year (CNY) and non-Chinese New Year (NCNY) periods were used. We documented evidence of a "holiday effect", where air pollutant concentrations were significantly different between holidays (CNY) and non-holidays (NCNY), in the Taipei metropolitan area over the past thirteen years (1994-2006). The concentrations of NOx, CO, NMHC, SO2 and PM10 were lower in the CNY than in the NCNY period, while the variation of O3 was reversed, which was mainly due to the NO titration effect. Similar differences in these six air pollutants between the CNY and NCNY periods were also found in the diurnal cycle and in the interannual variation. For the diurnal cycle, a common traffic-related double-peak variation was observed in the NCNY period, but not in the CNY period. Impacts of dust storms were also observed, especially on SO2 and PM10 in the CNY period. In the 13-year period of 1994-2006, decreasing trends of NOx and CO in the NCNY period implied a possible reduction of local emissions. Increasing trends of SO2 and PM10 in the CNY period, on the other hand, indicated a possible enhancement of long-range transport. These two mechanisms weakened the holiday effect.

  16. A 'beautiful death': mortality, death, and holidays in a Mexican municipality.

    Wilches-Gutiérrez, José L; Arenas-Monreal, Luz; Paulo-Maya, Alfredo; Peláez-Ballestas, Ingris; Idrovo, Alvaro J

    2012-03-01

    Several studies have reported increased mortality during holidays. Using a cultural epidemiological, sequential mixed-methods approach, this study explored holiday-related trends using mortality data from Yautepec (Morelos, Mexico) collected between 1986 and 2008 (N=5027 deaths). This analysis found that mortality increased on Christmas Day and All Saints' Day. Mortality increased on Candlemas Day among women, and increased on New Year's Day among men. More deaths caused by cardiovascular disease among women and traumatic injuries among men occurred during holidays than in non-holiday periods. To ascertain the elements comprising the health/illness/death process in the context of a holiday in this municipality, we conducted semi-structured interviews in March and April 2009 with relatives of seven individuals who had died during holidays in the previous 4 years (N=11); data from these interviews were analyzed from a grounded theory perspective to ascertain common conceptual themes. The "beautiful death" emerged as the main concept in the interpretation of death; this concept was related to the expectation of a good death and the particularly special nature of death during a holiday because of the involvement of religious entities, such as God, the Virgin Mary, and/or a saint, at the moment of death. Quantitative and qualitative results provided information about the important effects of holidays, culture, and religious belief on mortality patterns within a Mexican context, and contributed to a better understanding of the relationships among mortality, the nature of death, and holidays. Our results suggest that, in the studied region, death can be interpreted as a "beautiful process". More research is needed to explore this process in other similar contexts and to address topics related to the care and attention given the dying person and the expectation of a good death.

    This study investigated the influence of indium accumulation happened on the surface of a-plane InN grown under different growth conditions. Three different growth rates with N/In ratio from stoichiometric to N-rich were used to grow a-plane InN epifilms on GaN-buffered r-plane sapphires by plasma-assisted molecular beam epitaxy. When a-plane InN was grown above 500 °C with a high growth rate, abnormally high in-situ reflectivity was found during a-plane InN growth, which was resulted from indium accumulation on surface owing to In-N bonding difficulty on certain crystal faces of a-plane InN surface. Even using excess N-flux, indium accumulation could still be found in initial growth and formed 3-dimension-like patterns on a-plane InN surface which resulted in rough surface morphology. By reducing growth rate, surface roughness was improved because indium atoms could have more time to migrate to suitable position. Nonetheless, basal stacking fault density and crystal anisotropic property were not affected by growth rate. - Highlights: • High growth temperature could cause indium accumulation on a-plane InN surface. • Indium accumulation on a-plane InN surface causes rough surface. • Low growth rate improves surface morphology but not crystal quality.

    Highlights: • A comprehensive adsorption mechanism of InN monolayer is theoretical studied to distinguish the physic/chemi-sorption. • Different adsorption sites for different gases are systematically discussed. • The influence (enhanced or weakened) of external electric field to InN-gas system is well investigated. • The influences of gas adsorption to the optical properties (work function and light adsorption ability) of InN monolayer are also researched. - Abstract: Using first-principles calculation within density functional theory (DFT), we study the gas (CO, NH{sub 3}, H{sub 2}S, NO{sub 2}, NO, SO{sub 2}) adsorption properties on the surface of single-layer indium nitride (InN). Four different adsorption sites (Bridge, In, N, Hollow) are chosen to explore the most sensitive adsorption site. On the basis of the adsorption energy, band gap and charge transfer, we find that the most energetic favourable site is changeable between In site and N site for different gases. Moreover, our results reveal that InN is sensitive to NH{sub 3}, SO{sub 2}, H{sub 2}S and NO{sub 2}, by a physisorption or a chemisorption nature. We also perform a perpendicular electric field to the system and find that the applied electric field has a significant effect for the adsorption process. Besides, we also observed the desorption effects on NH{sub 3} adsorbed at the hollow site of InN when the electric field applied. In addition, the optical properties of InN monolayer affected by different gases are also discussed. Most of the gas adsorptions will cause the inhibition of light adsorption while the others can reduce the work function or enhance the adsorption ability in visible region. Our theoretical results indicate that monolayer InN is a promising candidate for gas sensing applications.

  1. Temporal settling of holidays and annual customs in villages at the foot of the Avala mountain

    Ivanović-Barišić Milina M.

    2004-01-01

    Full Text Available The life of rural population in villages at the foot of the Avala Mountain was marked by a constant shift of working days - when the local population had to ensure its existence - and idle days. Various holiday occasions altered the regularities of everyday life. During a holiday celebration the whole village community, as well as individuals, had to adopt a new way of behavior - i.e., to discontinue all work obligations that filled regular working days. In the past, these idle days were equally important for families and their members, and for the rural community in general. On the whole, the holidays appear in an annual cycle, discernible in a parallel mode: 1, Weekly and 2, Annual celebrations. The Weekly cycle is celebrated on Sundays, while the annual cycle celebrated various family' holidays or just days marked as "holidays". During the celebration of holidays participants departed from their everyday existing conditions and attuned to the Holy time, generated during holidays. Various rituals and customs used to be performed that not only added to the holiday ambiance, but also ensured the well-being of the family and rural community, and protected in this way, against misfortune. This period was marked by profound changes in family and community organizations. The changes in rural areas are the result of the rural population mass relocation in search for work and the beginning of urbanization. The process of industrialization along with the influx of the authorities onto traditional folk culture have left permanent consequences in the rural community settings and inherited folk culture.

    This paper describes our recent progress on InN, In-rich In{sub x}Ga{sub 1-x}N, and InN/In{sub x}Ga{sub 1-x}N quantum wells (QWs) grown by radio-frequency plasma-assisted molecular-beam epitaxy. Among the essential growth sequences to obtain high-quality InN, the nitridation process of (0001) sapphire substrates was reexamined. It was found that the lower-temperature and longer-period nitridation-process was very effective in improving crystalline quality of InN films. We succeeded in dramatically improving c -axis orientation of InN films without deteriorating their a -axis orientation by nitridating the substrates at a relatively low-temperature of 300 C for a relatively long period of 2 h. The full widths at half maximum (FWHMs) of (0002) X-ray rocking curves as narrow as 1 arcmin were obtained from only 400 nm thick InN films. These FWHMs are the narrowest value ever reported for InN and moreover approximately a twentieth part of the values obtained from our conventional InN films with a similar thickness, which were grown via the conventional nitridation process carried out at 550 C for 1 h. Furthermore interference fringes in X-ray diffraction ({omega}-2{theta} scan) were observed from these improved InN films. These high crystalline quality InN layers have been employed as a template for the growth of In-rich In{sub x}Ga{sub 1-x}N layers (0.70{<=}x{<=}0.94). The resultant In{sub x}Ga{sub 1-x}N layers have shown dramatic improvements in not only the surface morphology but also both the a- and c-axis orientations. By employing In{sub 0.8}Ga{sub 0.2}N layers of improved quality as the bottom barrier layer, InN/In{sub 0.8}Ga{sub 0.2}N multiple quantum well (MQW) and single quantum well (SQW) structures with different well widths were fabricated. Clear satellite peaks of X-ray diffraction were observed from these MQW structures. Both of these SQW and MQW structures have exhibited a blue shift of the photoluminescence peak energy with decreasing well width

    Among the group-III nitrides semiconductors, InN is the one with the narrowest gap (0.67 eV), lowest effective electron mass and highest peak drift velocity. It is therefore a very interesting material for several applications, in particular semiconductor solar cells. Furthermore, the high electron affinity makes it suitable also as electrode material for organic solar cells. InN layers were grown by molecular beam epitaxy on MOCVD GaN templates, on bare c-plane sapphire and on polycrystalline indium tin oxide. On all substrates the III-V ratio as well as the substrate temperature was varied. A RHEED analysis of InN growth on GaN showed a relatively sharp transition from N-rich and columnar growth to In-rich growth with droplet formation by increasing the In flux impinging on the surface. The InN layers on single crystalline substrates were characterized by SEM, AFM, XRD, PL and Raman. The InN layers on ITO were mainly analyzed with respect to the surface morphology with SEM. HRTEM in cross section gives insight into the structure of the interface to the ITO substrate.

  5. A comparative study on MOVPE InN grown on Ga- and N-polarity bulk GaN

    Wang, W.J.; Miwa, H.; Hashimoto, A.; Yamamoto, A.

    2006-01-01

    The influence of substrate polarity on the growth of InN film by MOVPE was investigated using bulk GaN as a substrate. Single-crystalline In- and N-polarity InN films were obtained on Ga- and N-polarity GaN substrate, respectively. Significant difference of the morphologies between the In- and N-polarity InN films was found. For the In-polarity InN film, the morphology was similar to that grown on sapphire substrate. The film surface was consisted of grains with small facets. In contrast, for the N-polarity InN film, the surface was consisted of large hexagonal shape crystal grains with flat surface. The grain size was about 2 μm in diameter on the average, and two-dimensional growth was enhanced obviously for each crystal grain. The influence of the growth temperature on the morphology, polarity, and optical property was also investigated. (copyright 2006 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim) (orig.)

    Critical aspects of InN channel field-effect transistors (FETs) have been investigated. SiN{sub x} dielectric layers were deposited in-situ, in the molecular beam epitaxy system, on the surface of 2 nm InN layers grown on GaN (0001) buffer layers. Metal-insulator-semiconductor Ni/SiN{sub x}/InN capacitors were analyzed by capacitance-voltage (C-V) and current-voltage measurements and were used as gates in InN FET transistors (MISFETs). Comparison of the experimental C-V results with self-consistent Schrödinger-Poisson calculations indicates the presence of a positive charge at the SiN{sub x}/InN interface of Q{sub if} ≈ 4.4 – 4.8 × 10{sup 13 }cm{sup −2}, assuming complete InN strain relaxation. Operation of InN MISFETs was demonstrated, but their performance was limited by a catastrophic breakdown at drain-source voltages above 2.5–3.0 V, the low electron mobility, and high series resistances of the structures.

  7. Holiday Destination Choice Behavior Analysis Based on AFC Data of Urban Rail Transit

    2015-01-01

    Full Text Available For urban rail transit, the spatial distribution of passenger flow in holiday usually differs from weekdays. Holiday destination choice behavior analysis is the key to analyze passengers’ destination choice preference and then obtain the OD (origin-destination distribution of passenger flow. This paper aims to propose a holiday destination choice model based on AFC (automatic fare collection data of urban rail transit system, which is highly expected to provide theoretic support to holiday travel demand analysis for urban rail transit. First, based on Guangzhou Metro AFC data collected on New Year’s day, the characteristics of holiday destination choice behavior for urban rail transit passengers is analyzed. Second, holiday destination choice models based on MNL (Multinomial Logit structure are established for each New Year’s days respectively, which takes into account some novel explanatory variables (such as attractiveness of destination. Then, the proposed models are calibrated with AFC data from Guangzhou Metro using WESML (weighted exogenous sample maximum likelihood estimation and compared with the base models in which attractiveness of destination is not considered. The results show that the ρ2 values are improved by 0.060, 0.045, and 0.040 for January 1, January 2, and January 3, respectively, with the consideration of destination attractiveness.

  8. Motor vehicle-related deaths around two major holidays in South Korea.

    Sohn, Kitae

    2017-10-01

    South Korea has consistently exhibited high rates of motor vehicle-related deaths (MVDs) since the late 1980s. This study investigated the number of MVDs around two major public holidays in South Korea-Lunar New Year's Day and Thanksgiving Day. MVDs from records of all individual deaths in 1997-2014 were extracted; then, MVDs per day from 14 days before and after each holiday (ie, 29 days in total) were summed across the years. Eventually, the 3-day mean values of MVDs before and after the holiday were compared, when holiday-related traffic peaks. The 3-day mean before Lunar New Year's Day was 385 fatalities, but dropped to 324 after the holiday; the corresponding figures for Thanksgiving Day were 494 and 413. These results are contrary to those of other countries. It appears that the severe congestion of highway traffic around the holidays resulted in a decrease in MVDs.

    2006-07-01

    Relative to the amount of electricity consumed by households, the consumption in holiday cottages is minor. In Denmark however, the past development in electricity consumption in holiday cottages differs significantly from the general trend in household electricity consumption. While the electricity consumption per household has been almost constant since the 1990s, the consumption per holiday cottage has increased 40 %. In addition, many new holiday cottages have been built and since 1990 the total electricity consumption has increased by 55 %. To find the reason for the increasing electricity consumption and to estimate the future demand of electricity for holiday cottages, a multidisciplinary study combining top-down and bottom-up estimations was carried out. In the top-town estimation, econometrics on aggregated data and general past trends analyses were combined. Dealing with statistics of time-series for the total electricity consumption in a number of holiday cottages, it was possible to interpret the past trends and to extrapolate the actual consumption for the year 2005 to the annual consumption in 2015.

  10. Exploring Intracity Taxi Mobility during the Holidays for Location-Based Marketing

    Wen-jun Wang

    2017-01-01

    Full Text Available Taxi mobility information can be considered as an important source of mobile location-based information for making marketing decisions. So, studying the behavioral patterns of taxis in a Chinese city during the holidays using the global positioning system (GPS can yield remarkable insights into people’s holiday travel patterns, as well as the odd-even day vehicle prohibition system. This paper studies the behavioral patterns of taxis during specific holidays in terms of pick-up and drop-off locations, travel distance, mobile step length, travel direction, and radius of gyration on the basis of GPS data. Our results support the idea of a polycentric city. It is concluded from the reporting results that there are no significant changes in the distribution of pick-up and drop-off locations, travel distance, or travel direction during holidays in comparison to work days. The results suggest that human travel by taxi has a stable regularity. However, the radius of gyration of movement by most of the taxis becomes significantly larger during holidays that indicate more long-distance travels. The current study will be helpful for location-based marketing during the holidays.

    2008-07-01

    Full Text Available House dust mites have been shown to be strongly associated with allergic respiratory diseases such as, bronchial asthma, rhinitis and atopic dermatitis in the world. The climatic conditions of Bandar-Abbas, which is located in a coastal area and has a humid subtropical climate, provide a suitable place to proliferate mites. The aim of this study was to determine the contamination rate and analyze the house dust mite fauna in hotels and inns in Bandar-Abbas that had not been investigated previously. In this study 6 hotels and 6 inns were selected randomly in six areas of Bandar-Abbas. Two dust samples were collected from each place with a vacuum cleaner. One square meter of carpets and mattresses were vacuumed for a period of 1 min. Then the samples were cleared in lactic acid and then mites were mounted in Hoyer's medium for study and identification. A total of 2644 mites were collected and identified. The major mite family was Pyroglyphidae (98%. Dermatophagoides pteronyssinus was the most frequent and most numerous species recorded, occurring in 91% of samples examined and forming 88% of the Pyroglyphidae and 86% of the total mite populations. The family Cheyletidae was less commonly found with Cheyletus malaccensis (2%. Most of the mites were isolated from the carpets (57.5%, and a smaller number from mattresses (42.5%. Mites were present in 96% of the dust samples. Results revealed that all inns and 83% of hotels were contaminated by more than one species of mite and 34% of them had a population of more than 100 mites /g dust. This rate of contamination can be a major risk factor in asthma and other respiratory allergic diseases

    We have investigated the growth of InN films by plasma assisted molecular beam epitaxy on the Si-face of 6H-SiC(0001). Growth is performed under In-rich conditions using a two-step process consisting of the deposition of a thin, low-temperature 350 C InN buffer layer, followed by the subsequent deposition of the InN epitaxial layer at 450 C. The effect of buffer annealing is investigated. The structural and optical evolution of the growing layer has been monitored in real time using RHEED and spectroscopic ellipsometry. Structural, morphological, electrical and optic properties are discussed. (copyright 2006 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim) (orig.)

    2013-04-01

    We report the growth of InN quantum dots (QDs) on thick InGaN layers with high In composition (>50%) by molecular beam epitaxy. Optimized growth conditions are identified for the InGaN layers at reduced growth temperature and increased active N flux resulting in minimized phase separation and defect generation. The InN QDs grown on top of the optimized InGaN layer exhibit small size, high density, and photoluminescence up to room temperature. The InN/InGaN QDs reveal excellent potential for intermediate band solar cells with the InGaN and InN QD bandgap energies tuned to the best match of absorption to the solar spectrum.

    The dietary pattern has influences on nutritional status. In this activity, we compared micro nutrient intake of elementary school children (7-12 years) as a consequence of dietary pattern difference on holiday and schooldays, due to most of their time was spend in school where the tendency of snack consuming is usually higher at school. Therefore, the comparison of dietary pattern and micro nutrient daily intake of elementary school children on holiday and schooldays was needed to carry out. Food sampling was done by duplicate diet method for 3 days in a row with one day among them was a holiday. The determination of micro nutrient elements concentration was measured using instrumental neutron activation analysis (INAA) and atomic absorption spectrometry (AAS). There was a significant difference of daily intake of Na, K, Ca, Fe, and Cr on holiday and schooldays, while for Br, Mg, Zn, Mn, Cu, Se and Co were no significant difference. The most significant difference contained on sodium intake with average daily intake was 2578 mg/day on schooldays and 1298 mg/day on holiday. It was caused by the number of high sodium content snacks consumed on schooldays were bigger than on holiday. However, the results of micro nutrient daily intake obtained either on schooldays or on holiday generally were below RDA (Recommended Dietary Allowance), except for Na and Cr. It's expected that this result could be used as information about nutrition status of children as next generation on behalf of supporting the formation of high quality human resources. (author)

    Wing, Yun Kwok; Li, Shirley Xin; Li, Albert Martin; Zhang, Jihui; Kong, Alice Pik Shan

    2009-11-01

    A growing trend in childhood sleep habits is to compensate for the weekday sleep deficit by longer weekend and holiday sleep duration. We aimed to investigate the effect of weekend/holiday sleep compensation in relation to childhood overweight and obesity. This is a community-based cross-sectional study with 5159 children (49.6% boys), mean age of 9.25 years (SD: 1.78), from 13 primary schools in Hong Kong. Data on sleep patterns, lifestyle, body weight, and height of children were obtained from questionnaires. Sleep durations during weekdays, weekends, and holidays were predictor variables. BMI z scores and obesity/overweight status were the outcome measures. Children slept significantly longer during holidays (mean [SD]: 10.20 (0.92) hours) and weekends (school terms) (10.07 [0.93] hours) than during school weekdays (9.18 [0.95] hours). Children with shorter sleep duration had higher BMI z scores regardless of the sleep parameters used in the analysis. Among children who slept holidays had significantly increased risk of overweight/obesity compared with those children with sleep compensation (odds ratios: 2.59 [95% confidence interval: 1.22-5.48] and 2.32 [95% confidence interval: 1.00-5.53], respectively). There was a prominent difference in sleep duration between weekdays and weekends/holidays among school children. Short sleep duration was associated with higher BMI, but compensation of sleep during weekends/holidays may partly ameliorate the risk of childhood overweight/obesity. Further prospective and interventional study is needed to delineate the risk-benefit effect of these increasingly common sleep habits among children and adolescents.

    2014-01-01

    To assess whether mortality of patients admitted on weekends and public holidays was higher in a district general hospital whose consultants are present more than 6 h per day on the acute medical unit with no other fixed clinical commitments. Cohort study. Secondary care. All emergency medical admissions to Dumfries and Galloway Royal Infirmary between 1 January 2008 and 31 December 2010. We examined 7 and 30 day mortality for all weekend and for all public holiday admissions, using all weekday and non-public holiday admissions, respectively, as comparators. We adjusted mortality for age, gender, comorbidity, deprivation, diagnosis and year of admission. 771 (3.8%) of 20 072 emergency admissions died within 7 days of admission and 1780 (8.9%) within 30 days. Adjusted weekend mortality in the all weekend versus all other days analysis was not significantly higher at 7 days (OR 1.10, 95% CI 0.92 to 1.31; p=0.312) or at 30 days (OR 1.07, 95% CI 0.94 to 1.21; p=0.322). By contrast, adjusted public holiday mortality in the all public holidays versus all other days analysis was 48% higher at 7 days (OR 1.48, 95% CI 1.12 to 1.95; p=0.006) and 27% higher at 30 days (OR 1.27, 95% CI 1.02 to 1.57; p=0.031). Interactions between the weekend variable and the public holiday variable were not statistically significant for mortality at either 7 or 30 days. Patients admitted as emergencies to medicine on public holidays had significantly higher mortality at 7 and 30 days compared with patients admitted on other days of the week.

  19. Bisphosphonate Treatment in Osteoporosis: Optimal Duration of Therapy and the Incorporation of a Drug Holiday.

    Villa, Jordan C; Gianakos, Arianna; Lane, Joseph M

    2016-02-01

    Bisphosphonates are the most widely used treatment for osteoporosis. They accumulate in the bone for years, and therefore, their inhibitory effects on osteoclasts may persist after drug discontinuation. The ideal duration of therapy remains controversial. The purpose of this study is to review the literature to determine the (1) indications for drug holiday, (2) the duration of drug holiday, (3) the evaluation during drug holiday, and (4) the proper treatment and maintenance after drug holiday. A review of two electronic databases (PubMed/MEDLINE and EMBASE) was conducted using the term "(Drug holiday)," in January 29, 2015. Inclusion criteria were as follows: (1) clinical trials and case control, (2) human studies, (3) published in a peer-review journal, and (4) written in English. Exclusion criteria were as follows: (1) case reports, (2) case series, and (3) in vitro studies. The literature supports a therapeutic pause after 3-5 years of bisphosphonate treatment in patients with minor bone deficiencies and no recent fragility fracture (low risk) and in patients with moderate bone deficiencies and/or recent fragility fracture (moderate risk). In these patients, a bone health reevaluation is recommended every 1-3 years. Patients with high fracture risk should be maintained on bisphosphonate therapy without drug holiday. The duration and length of drug holiday should be individualized for each patient. Evaluation should be based on serial bone mass measurements, bone turnover rates, and fracture history evaluation. If after drug therapy, assessments show an increased risk of fracture, the patient may benefit from initiating another treatment. Raloxifene, teriparatide, or denosumab are available options.

  20. Investigation of InN layers grown by MOCVD using analytical and high resolution TEM: The structure, band gap, role of the buffer layers

    2006-01-01

    In this work we investigate the microstructure of InN layers grown by MOCVD on different buffer layers using TEM (InN, GaN). The large mismatch between the various lattices (InN, sapphire or GaN) leads to particular interface structures. Our local analysis allows to show that at atomic scale, the material has the InN lattice parameters and that no metallic In precipitates are present, meaning that the PL emission below 0.8 eV is a genuine property of the InN semiconductor. It is also shown that the N polar layers, which exhibit a 2D growth, have poorer PL emission than In polar layers. (copyright 2006 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim) (orig.)

    2007-01-01

    C-axis oriented InN films with wurtzite structure were grown on sapphire(0001) substrate by MOCVD method. Superconductivity with transition onset temperature T c,onset around 3.5 K has been characterized by magnetotransport measurements in fields up to 9 Tesla for films with carrier concentration in the range of 1 x 10 19 cm -3 to 7 x 10 20 cm -3 . Among them, the film with a nitridation buffer layer has the highest zero-resistance temperature T c0 of 2 K. The normal-state magnetoresistance follows Kohler's rule ΔR/R∝(H/R) 2 , indicating that there is a single species of charge carrier with single scattering time at all points on the Fermi surface. The extrapolated value of zero-temperature upper critical field H c2 ab (0) and H c2 c (0) is estimated to be 5900 G and 2800 G, respectively, giving rise to the anisotropy parameter γ about 2.1. The angular dependence of the upper critical field is in good agreement with the behavior predicted by Lawrence-Doniach model in the two-dimensional (2D) limit strongly suggesting that the InN film is a quasi-2D superconductor.

  3. Characterization of as-grown and adsorbate-covered N-polar InN surfaces using in situ photoelectron spectroscopy

    Eisenhardt, Anja; Himmerlich, Marcel; Krischok, Stefan

    2012-01-01

    The surface electronic properties and adsorption behaviour of as-grown and oxidized N-polar InN films are characterized by photoelectron spectroscopy (XPS, UPS). The epitaxial growth of the InN layers was performed by plasma-assisted molecular beam epitaxy on GaN/6H-SiC(000-1). After growth and in situ characterization the InN surfaces were exposed to molecular oxygen to evaluate the adsorption behaviour of O 2 on N-polar InN and to study its impact on the surface electronic properties of the III-nitride material. The results are compared with studies on In-polar InN on GaN/sapphire templates. The as-grown N-polar InN surface exhibits a pronounced surface state at a binding energy of ∝1.6 eV. The valence band minimum lies about 0.8-1.0 eV below the surface Fermi level. Additionally, the XPS core level binding energies for InN(000-1) are reduced compared to InN(0001) films, indicating different surface band bending for clean N-polar and In-polar InN, respectively. The interaction of molecular oxygen with the InN(000-1) surface leads to a downward band bending by 0.1 eV compared to the initial state. Additional adsorption of species from the residual gas of the UHV chamber increases the surface downward band bending. Furthermore two pronounced oxygen related states with an energy distance of ∝5 eV could be detected in the valence band region. The adsorbed oxygen results in an additional component in the N1s core level spectra, which is interpreted as formation of NO x bonds. (Copyright copyright 2012 WILEY-VCH Verlag GmbH and Co.

  4. Position Statement: Drug Holiday in Osteoporosis Treatment with Bisphosphonates in South Korea

    Lee, Seung Hun; Gong, Hyun Sik; Kim, Tae-Hee; Park, Si Young; Shin, Jung-Ho; Cho, Sun Wook

    2015-01-01

    Bisphosphonates have been widely used in the treatment of osteoporosis with robust data from many placebo-controlled trials demonstrating its efficacy in fracture risk reduction over 3 to 5 years of treatment. Although bisphosphonates are generally safe and well tolerated, concerns have emerged about the adverse effects related to its long-term use, including osteonecrosis of the jaw and atypical femur fractures. Because bisphosphonates are incorporated into the skeleton and continue to exert an anti-resorptive effect for a period of time after the discontinuation of drugs, the concept of a "drug holiday" has emerged, whereby the risk of adverse effects might be decreased while the patient still benefits from anti-fracture efficacy. As randomized clinical trial evidence is not yet available on who may qualify for a drug holiday, there is considerable controversy regarding the selection of candidates for the drug holiday and monitoring during a drug holiday, both of which should be based on individual assessments of risk and benefit. This statement will provide suggestions for clinicians in South Korea on the identification of possible candidates and monitoring during a bisphosphonate drug holiday. PMID:26713307

  5. EXPLORING TAX HOLIDAY POLICY IMPLEMENTATION FOR INDONESIAN INVESTMENT CLIMATE: HAS IT BEEN EFFECTIVE?

    Mulyono R.D.P.

    2017-07-01

    Full Text Available This study aims to explore the reasons for the ineffectiveness of tax holiday policy implementation in Indonesia as well as the government’s strategies to improve the investment climate. This research uses exploratory study type which does not test theory or hypothesis by using preliminary survey method, conducting direct or indirect interview via e-mail to certain informant by giving questionnaire and direct observation passively observing the field and related websites supporting statistical data in this study in depth. In testing the validity of research data used source triangulation and method triangulation. The progress that has been achieved to date in the implementation of tax holiday policy is to provide ease of bureaucracy administration and simplicity of licensing services in investing by improving coordination among government to improve foreign investors' confidence when investing in Indonesia. So technically, the implementation of tax holiday policy is quite effective in attracting foreign direct investment because it can perform the right obligations according to the regulations. In the investment point of view, tax holiday policy is not effective in attracting foreign direct investment or not becoming the main factor of investor's goal in investment. The cause of the ineffectiveness of the tax holiday policy in attracting foreign direct investment in Indonesia is another indicator that becomes an assessment among others the ease of investment licensing, infrastructure, electricity supply, investor protection, minority and tax administration. Indonesian government's strategy to improve the investment climate is through deregulation, debureaucracy, law enforcement and business certainty for investors.

    Highlights: • Vertical InN nanorods are grown on selective areas of sapphire substrates. • In metal droplets nucleate on the sharp needle apexes on the selective areas. • The preferred orientation and the growth direction of the nanorods are (0 0 0 1). • The nanorods grow from the supersaturated indium melt on their tops. - Abstract: Vertically oriented InN nanorods were grown on selective areas of unintentionally patterned c-oriented sapphire substrates exhibiting sharp needles that preferentially accommodate In-metal liquid droplets, using Migration Enhanced Afterglow (MEAglow) growth technique. We point out that the formation of AlN needles on selected areas can be reproduced intentionally by over-nitridation of unmasked areas of sapphire substrates. The liquid indium droplets serve as a self-catalyst and the nanorods grow from the supersaturated indium melt in the droplet in a vertical direction. X-ray diffraction measurements indicate the presence of hexagonal InN only, with preferred orientation along (0 0 0 1) crystal axis, and very good crystalline quality. The room temperature Raman spectrum shows the presence of the A{sub 1}(TO), E{sub 2}(high) and A{sub 1}(LO) phonon modes of the hexagonal InN.

  7. Generation of ultra-small InN nanocrystals by pulsed laser ablation of suspension in organic solution

    Kursungoez, Canan; Uzcengiz Simsek, Elif; Ortac, Buelend; Tuzakli, Refik

    2017-01-01

    Nanostructures of InN have been extensively investigated since nano-size provides a number of advantages allowing applications in nanoscale electronic and optoelectronic devices. It is quite important to obtain pure InN nanocrystals (InN-NCs) to reveal the characteristic features, which gain interest in the literature. Here, we proposed a new approach for the synthesis of ultra-small hexagonal InN-NCs by using suspension of micron-sized InN powder in ethanol with pulsed laser ablation method. The liquid environment, laser energy and ablation time were optimized and a post-synthesis treatment, centrifugation, was performed to achieve InN-NCs with the smallest size. Besides, the micron-sized InN powder suspension, as a starting material, enabled us to obtain InN-NCs having diameters smaller than 5 nm. We also presented a detailed characterization of InN-NCs and demonstrated that the formation mechanism mainly depends on the fragmentation due to laser irradiation of the suspension. (orig.)

  8. The structural evolution of InN nanorods to microstructures on Si (111) by molecular beam epitaxy

    Anyebe, E A; Zhuang, Q; Kesaria, M; Krier, A

    2014-01-01

    We report the catalyst free growth of wurtzite InN nanorods (NRs) and microislands on bare Si (111) by plasma-assisted molecular beam epitaxy at various temperatures. The morphological evolution from NRs to three dimensional (3D) islands as a function of growth temperature is investigated. A combination of tapered, non-tapered, and pyramidal InN NRs are observed at 490 °C, whereas the InN evolves to faceted microislands with an increase in growth temperature to 540 °C and further developed to indented and smooth hemispherical structures at extremely high temperatures (630 °C). The evolution from NRs to microislands with increase in growth temperature is attributed to the lowering of the surface free energy of the growing crystals with disproportionate growth velocities along different growth fronts. The preferential adsorption of In atoms on the (0001) c-plane and (10-10) m-plane promotes the growth of NRs at relatively low growth temperature and 3D microislands at higher temperatures. The growth rate imbalance along different planes facilitates the development of facets on 3D microislands. A strong correlation between the morphological and structural properties of the 3D films is established. XRD studies reveal that the NRs and the faceted microislands are crystalline, whereas the hemispherical microislands grown at extremely high growth temperature contain In adlayers. Finally, photoluminescent emissions were observed at ∼0.75 eV from the InN NRs. (paper)

  9. First-principles study of Mg incorporation at wurtzite InN (0 0 0 1) and (0001-bar) surfaces

    Ding, S.F.; Qu, X.P.; Fan, G.H.

    2009-01-01

    In this article we investigate the energetics of Mg adsorption and incorporation at the InN(0 0 0 1) and InN(0001-bar) surfaces by the method of total energy plane-wave expansions with ultra-soft pseudo potential technology based on the density functional theory (DFT) in the generalized approximation (GGA). It is found that for a 1/4 monolayer (ML) coverage of the InN(0 0 0 1) surface, Mg atoms preferentially adsorb at the bridge sites and T4 sites, but they are unstable when compared with Mg incorporated in the first three layers. For a 1/4 ML coverage of the InN(0001-bar) surface, Mg atoms preferentially adsorb at the H3 sites with the formation energy of -3.49 (eV/(2x2) supercell), which is lower than that of the T4 sites, and the formation energy increases with increasing magnesium coverage. Further study shows that the formation energy for Mg atom is lower than that of In atom, which indicates that magnesium adsorption is more favorable in these conditions.

    Nanostructures of InN have been extensively investigated since nano-size provides a number of advantages allowing applications in nanoscale electronic and optoelectronic devices. It is quite important to obtain pure InN nanocrystals (InN-NCs) to reveal the characteristic features, which gain interest in the literature. Here, we proposed a new approach for the synthesis of ultra-small hexagonal InN-NCs by using suspension of micron-sized InN powder in ethanol with pulsed laser ablation method. The liquid environment, laser energy and ablation time were optimized and a post-synthesis treatment, centrifugation, was performed to achieve InN-NCs with the smallest size. Besides, the micron-sized InN powder suspension, as a starting material, enabled us to obtain InN-NCs having diameters smaller than 5 nm. We also presented a detailed characterization of InN-NCs and demonstrated that the formation mechanism mainly depends on the fragmentation due to laser irradiation of the suspension. (orig.)

  11. The Connection between Professional Sporting Events, Holidays and Domestic Violence in Calgary, Alberta

    Full Text Available There are some days in Calgary, Alta when domestic violence is more likely to happen than other days. There is a statistically significant connection between higher rates of domestic violence and certain Calgary Stampeders’ football games as well as the arrival of the Calgary Stampede. During the 10-day-long Calgary Stampede, domestic violence calls on the seventh, ninth and tenth day of Stampede, were up 15 per cent compared to an average day. Weekends and summer months were also generally associated with the highest rates of domestic violence reports in Calgary. When it came to Calgary Stampeders’ football games, calls were higher only when the Stampeders faced off against the rival Edmonton Eskimos – with a 15 per cent increase in domestic violence reports. Grey Cup games in which Calgary played were associated with a 40 per cent increase in reports of domestic violence. However, games played by the Calgary Flames seemed to have no relationship to domestic violence calls, even those against the rival Edmonton team. Also, New Year’s Day appears to be associated with a significant spike in domestic violence, going by a four-year count of phone calls reporting domestic violence to both police and a local help line for those experiencing domestic and sexual abuse. There are also increases in calls associated with Good Friday, Easter, Canada Day, Labour Day, Valentine’s Day and Halloween. Meanwhile, the 2013 catastrophic floods in Calgary resulted in an increase in reports of domestic violence to police and the Connect help line, averaging an additional 6.6 reported incidents of domestic violence per day during the flood, 14 per cent higher than average. A correlation was also found in Calgary between the fall in oil prices and the rise in calls, with every US$10 fall in the price of West Texas Intermediate resulting in an extra call for help every two days. Since reducing domestic violence requires recognizing possible contributing

  19. A Novel Scheme to Relieve Parking Pressure at Tourist Attractions on Holidays

    Juan Li

    2016-02-01

    Full Text Available Parking is a key component of urban transportation managements and has become a severe problem at many tourist attractions during holidays in China. This paper presents a novel scheme to relieve the holiday parking pressure. Based on the perspectives of the activity-based travel characteristics, we propose an effort to develop parking alternatives by utilizing existing traffic facilities. A conceptual model is employed to explore the influence of additional leisure activity of parking and various options of transportation modes. The results indicate that compared to commuters, the scenery is the major factor affecting tourists’ parking preference, besides parking time and cost. Based on the finding, a tourist-centered strategy is designed to satisfy the peak hours parking demands in order to relieve the parking pressure at tourist attractions during holidays.

  20. Sun behaviour and personal UVR exposure among Europeans on short term holidays

    Petersen, Bibi; Triguero-Mas, Margarita; Maier, Bernhard

    2015-01-01

    Solar ultraviolet radiation (UVR) is known to be the main cause of skin cancer, the incidence of which is rising with national differences across Europe. With this observation study we aimed to determine the impact of nationality on sun behaviour and personal UVR exposure on sun and ski holidays....... 25 Danish and 20 Spanish sun-seekers were observed during a sun holiday in Spain, and 26 Danish and 27 Austrian skiers were observed during a ski holiday in Austria. The participants recorded their location and clothing in diaries. Personal time-logged UVR data were recorded as standard erythema...... doses (SEDs) by an electronic UVR dosimeter worn on the wrist. Danish sun-seekers were outdoors for significantly longer, received significant higher percentages of ambient UVR, and received greater accumulated UVR doses than Spanish sun-seekers. Danish skiers were also outdoors for significantly longer...

  1. Bisphosphonate Drug Holiday and Fracture Risk: A Population-Based Cohort Study.

    Holidays from bisphosphonates (BPs) may help to prevent rare adverse events like atypical femoral fractures, but may be appropriate only if risk of osteoporosis-related fractures does not increase. Our objective was to compare the incidence of osteoporosis-related fractures among women who had a bisphosphonate (BP) holiday to those who continued use BPs. This retrospective cohort study, conducted within 4 Kaiser Permanente integrated health system regions, included 39,502 women aged ≥45 years with ≥3 years exposure to BP. Participants with a BP holiday (≥12 months with no use) were compared to persistent (use with ≥50% adherence) and non-persistent (use with holiday (n = 11,497), non-persistent user (n = 10,882), and persistent user groups (n = 17,123) were observed for 156,657 person-years. A total of 5,199 osteoporosis-related fractures (including 1,515 hip fractures and 2,147 vertebral fractures) were observed. Compared to the persistent use group, there was a slight difference in overall osteoporosis-related fracture risk (HR 0.92, 95% CI 0.84-0.99)and no difference in hip fracture risk (HR 0.95, 95% CI 0.83-1.10) for the BP holiday group. A slight reduction in risk of vertebral fracture was observed (HR 0.83, 95% CI 0.74-0.95). Compared to the non-persistent user group, the BP holiday group was at decreased risk for osteoporosis-related fractures (HR 0.71, 95% CI 0.65-0.79), vertebral fractures (HR 0.68, 95% CI 0.59-0.78), and hip fractures (HR 0.59; 95% CI 0.50-0.70). Women who undertake a BP holiday from BP of ≥12 months duration for any reason after ≥3 years of BP use do not appear to be at greater risk of osteoporosis-related fragility fracture, hip, or vertebral fractures compared to ongoing BP users. In our cohort, BP holiday remains a viable strategy for balancing the benefits and potential harms associated with long-term BP use. This article is protected by copyright. All rights reserved.

    2017-12-01

    A cohort of 183 postmenopausal women, who had either discontinued or continued bisphosphonates (BPs) after first-line therapy, was used to investigate the relationships between "drug holiday" and clinical fracture. The risk of new clinical fractures was found to be 40% higher in women who had taken a BP "drug holiday." BPs are the most widely used treatment for postmenopausal osteoporosis. The optimal treatment duration, however, remains unclear. The purpose of this study was to evaluate the fracture risk in postmenopausal women with osteoporosis after discontinuing BP treatment (BP "drug holiday"). A retrospective analysis was performed at Lille University Hospital (LUH) on postmenopausal women with osteoporosis who had taken a "drug holiday" or continued treatment after first-line BP therapy (3 to 5 years). The occurrence of new clinical fractures during follow-up was also explored. Cox proportional hazards models were used to investigate the relationships between BP "drug holiday" and the occurrence of clinical fractures, while controlling for confounding factors. Survival without new clinical fractures was analyzed using Kaplan-Meier curves and log-rank tests. One hundred eighty-three women (mean age: 61.8 years; SD: 8.7) who had previously undergone BP treatment for 3 to 5 years were enrolled in our study. The patients had received alendronate (n = 81), risedronate (n = 73), zoledronic acid (n = 20), and ibandronate (n = 9). In 166 patients ("drug holiday" group: n = 31; continuous-treatment group: n = 135), follow-up ranged from 6 to 36 months (mean duration: 31.8 months; SD: 8.2). The incidences of new clinical fractures during follow-up were 16.1% (5/31) and 11.9% (16/135). After full adjustment, the hazard ratio of new clinical fractures among "drug holiday" patients was 1.40 (95% CI: 1.12-1.60; p = 0.0095). After first-line BP therapy in postmenopausal women with osteoporosis, the risk of new clinical fractures was 40% higher in

  3. The Comparative Analysis of Senior and Non-Senior Package Holiday Travelers' Tourism Product Preferences

    Maria Johann

    2015-10-01

    Full Text Available Tourism products are systemic products which offer multiple value to tourists in multiple aspects to satisfy their needs, however, tourists' preferences vary in terms of travelers' characteristics. The current study attempts to analyse senior and non-senior package holiday travelers' preferences with respect to tourism product attributes. The surveyed sample of 463 tourists spent their holiday on the coach tours in Poland in 2013. The main implication of this research for tourism product managers is that they have to focus on providing tourists with well suited packages and position appropriately by selecting suitable communication strategies for selected target segments.

  4. Photoluminescence and Raman spectroscopy of MBE-grown InN nanocolumns

    2008-01-01

    InN nanocolumns grown under different conditions by plasma-assisted molecular beam epitaxy on p-Si (111) substrates are studied by micro-Raman and photoluminescence (PL) spectroscopies. The nanocolumns are free of strain and have an improved crystal quality as shown by the frequency and linewidth of the nonpolar E 2 h mode. Uncoupled polar modes coexist with a couple LO phonon-plasmon mode and are sensitive to the nanocolumn morphology. Variations in the growth conditions also modify the PL spectra significantly. An increase in the PL energy also involves a reduction of the integrated intensity and an increase of the PL linewidth. This overall phenomenology highlights the role of the surface accumulation layer in these nanostructures. (copyright 2008 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim) (orig.)

  6. Optical studies of MBE-grown InN nanocolumns: Evidence of surface electron accumulation

    Segura-Ruiz, J.; Garro, N.; Cantarero, A.; Denker, C.; Malindretos, J.; Rizzi, A.

    2009-03-01

    Vertically self-aligned InN nanocolumns have been investigated by means of scanning electron microscopy, Raman scattering, and photoluminescence spectroscopy. Different nanocolumn morphologies corresponding to different molecular beam epitaxy growth conditions have been studied. Raman spectra revealed strain-free nanocolumns with high crystalline quality for the full set of samples studied. Longitudinal optical modes both uncoupled and coupled to an electron plasma coexist in the Raman spectra pointing to the existence of two distinctive regions in the nanocolumn: a surface layer of degenerated electrons and a nondegenerated inner core. The characteristics of the low-temperature photoluminescence and its dependence on temperature and excitation power can be explained by a model considering localized holes recombining with degenerated electrons close to the nonpolar surface. The differences observed in the optical response of different samples showing similar crystalline quality have been attributed to the variation in the electron accumulation layer with the growth conditions.

  7. Magnetic-field and temperature dependence of the energy gap in InN nanobelt

    K. Aravind

    2012-03-01

    Full Text Available We present tunneling measurements on an InN nanobelt which shows signatures of superconductivity. Superconducting transition takes place at temperature of 1.3K and the critical magnetic field is measured to be about 5.5kGs. The energy gap extrapolated to absolute temperature is about 110μeV. As the magnetic field is decreased to cross the critical magnetic field, the device shows a huge zero-bias magnetoresistance ratio of about 400%. This is attributed to the suppression of quasiparticle subgap tunneling in the presence of superconductivity. The measured magnetic-field and temperature dependence of the superconducting gap agree well with the reported dependences for conventional metallic superconductors.

    2016-01-01

    Access to an adequate supply of nutritious food has been recognized as a basic human right. However, many families across the UK face food insecurity, which is thought to be exacerbated during school holidays. To address this issue, some schools and community groups have chosen to roll out holiday clubs, though research into the effectiveness of such interventions is limited and no studies to date have evaluated holiday clubs being organized through schools. In an effort to address some of the limitations in the research literature, the current qualitative investigation utilized semi-structured interviews with staff involved in holiday clubs in school and community venues with the aim of gaging their views on the need for and benefits of holiday food provision in addition to potential areas for development. The investigation revealed that staff perceived many families to be facing food insecurity and isolation during the school holidays, which may be alleviated through holiday club provision. Holiday clubs were viewed as a valuable source of support for children and adults, providing food, activities, and learning experiences. Staff were keen to see them implemented on a wider scale in future but suggested some areas that require attention in any future development of such provision. Findings are discussed in relation to current research, policy, and practice surrounding the health and wellbeing of children and families.

  18. Occupancy modeling and estimation of the holiday darter species complex within the Etowah River system

    Anderson, Gregory B.; Freeman, Mary C.; Hagler, Megan M.; Freeman, Byron J.

    2012-01-01

    Documenting the status of rare fishes is a crucial step in effectively managing populations and implementing regulatory mechanisms of protection. In recent years, site occupancy has become an increasingly popular metric for assessing populations, but species distribution models that do not account for imperfect detection can underestimate the proportion of sites occupied and the strength of the relationship with a hypothesized covariate. However, valid detection requires temporal or spatial replication, which is often not feasible due to logistical or budget constraints. In this study, we used a method that allowed for spatial replication during a single visit to evaluate the current status of the holiday darter species complex, Etheostoma sp. cf. E. brevirostrum, within the Etowah River system. Moreover, the modeling approach used in this study facilitated comparisons of factors influencing stream occupancy as well as species detection within sites. The results suggest that there is less habitat available for the Etowah holiday darter form (Etheostoma sp. cf. E. brevirostrum B) than for the Amicalola holiday darter form (Etheostoma sp. cf. E. brevirostrum A). Additionally, occupancy models suggest that even small decreases in forest cover within these headwater systems adversely affect holiday darter populations.

  19. DENTAL STUDENTS' PSYCHOLOGICAL WELL-BEING DURING EXAMINATION PERIOD AND HOLIDAY.

    Preoteasa, Cristina Teodora; Imre, Marina; Preoteasa, Elena

    2015-01-01

    Psychological well-being is recognized as an important health component, which influences the behavior, ability to cope with stressful events, work performance, and generally the ability to achieve one's full potential. To comparatively assess the psychological well-being of dental students during the summer semester examination period and summer holiday. A single-arm, prospective study was conducted in second year dental students from the Faculty of Dental Medicine, Bucharest. The psychological well-being was assessed using the WHO-Five Well-being Index. Students' psychological well-being was statistically significantly better during the summer holiday (median=19) than during the summer semester examination period (median = 11.5), Z = 3.69, p holiday, but it was significantly correlated with the WHO-Five Well-being Index score corresponding to the summer holiday, and no association was observed with the WHO-Five Well-being Index score corresponding to the summer semester examination period. Within the limits of this study, psychological well-being is likely to be negatively influenced, on a fairly large scale, by the semester examination period. Therefore, it is recommended to identify the most appropriate methods of examination with regards to the psychological load that might be a threat to the validity of students' evaluation. Additionally, training students about adequate coping strategies, designed as interventions at individual or group level, may be required.

    Several studies suggest that the holiday season, starting from the last week of November to the first or second week of January, could be critical to gaining weight. This study aims to review the literature to determine the effects of the holidays on body weight. In studies of adults, a significant weight gain was consistently observed during this period (0.4 to 0.9 kg, p 0.05) during this period. Among individuals with obesity who attempt to lose weight, an increase in weight was observed (0.3 to 0.9 kg, significant in some but not in all studies), as well as increase in weight in motivated self-monitoring people (0.4 to 0.6%, p holidays (phone calls and daily mailing) appeared to prevent weight gain, but information is limited. The holiday season seems to increase body weight in adults, even in participants seeking to lose weight and in motivated self-monitoring people, whereas in children, adolescents, and college students, very few studies were found to make accurate conclusions.

    2009-01-01

    Norovirus is increasingly recognized as a leading cause of outbreaks of foodborne disease. We report on an outbreak in Austria that reached a total of 176 cases, affecting pupils and teachers from four schools on a skiing holiday in a youth hostel in the province of Salzburg in December 2007. A questionnaire was sent to the four schools in order to obtain data from persons attending the school trip on disease status, clinical onset, duration of illness and hospitalization. A cohort study was undertaken to identify the sources of infection. The school trip attendees were interviewed by questionnaire or face-to-face on their exposure to food items from the menu provided by the hostel owner. Of the 284 school holiday-makers, 176 fitted the definition of an outbreak case (attack rate 61.9%). A total of 264 persons on the ski holiday participated in the cohort study (response rate 93%). The day-by-day food-specific analyses did not find any food items served on any of five days (December 8-12) of the holiday to be associated with infection risk. The day-specific risk analyses revealed Monday December 10 (RR: 9.04; 95% CI: 6.02-13.6; P Tourism is one of the primary industries in Austria. Timely involvement of the relevant public health authorities is essential in any outbreak of norovirus gastroenteritis, irrespective of its genesis.

    2013-03-01

    Full Text Available Abstract: Purpose: The train dispatching is a crucial issue in the train operation adjustment when passenger flow outbursts. During holidays, the train dispatching is to meet passenger demand to the greatest extent, and ensure safety, speediness and punctuality of the train operation. In this paper, a fuzzy passenger demand forecasting model is put up, then a train dispatching optimization model is established based on passenger demand so as to evacuate stranded passengers effectively during holidays. Design/methodology/approach: First, the complex features and regularity of passenger flow during holidays are analyzed, and then a fuzzy passenger demand forecasting model is put forward based on the fuzzy set theory and time series theory. Next, the bi-objective of the train dispatching optimization model is to minimize the total operation cost of the train dispatching and unserved passenger volume during holidays. Finally, the validity of this model is illustrated with a case concerned with the Beijing-Shanghai high-speed railway in China. Findings: The case study shows that the fuzzy passenger demand forecasting model can predict outcomes more precisely than ARIMA model. Thus train dispatching optimization plan proves that a small number of trains are able to serve unserved passengers reasonably and effectively. Originality/value: On the basis of the passenger demand predictive values, the train dispatching optimization model is established, which enables train dispatching to meet passenger demand in condition that passenger flow outbursts, so as to maximize passenger demand by offering the optimal operation plan.

    Studies suggest that there may be an association between sleep and growth; however, the relationship is not well understood. Changes in biology and external factors such as school schedule heavily impact the sleep of adolescents, during a critical phase for growth. This study assessed the changes in sleep across school days, weekends and school holidays, while also measuring height and weight changes, and self-reported alterations in food intake and physical activity. The impact of morningness-eveningness (M-E) on height change and weight gain was also investigated. In a sample of 63 adolescents (mean age = 13.13, SD = 0.33, 31 males) from two independent schools in South Australia, height and weight were measured weekly for 4 weeks prior to the school holidays and 4 weeks after the school holidays. Participants also completed a Morningness/Eveningness Scale and 7-day sleep, diet and physical activity diaries prior to, during and after the school holidays. Participants at one school had earlier wake times during the weekends than participants attending the other school, leading to a significantly shorter sleep duration on weekends for those participants. Regardless of school, sleep was significantly later and longer during the holidays (p holiday weeks. For those attending the school with limited sleep in opportunities, growth after the holidays was lower for those with greater evening preference, whereas for those at the other school, growth was greater for those with greater evening preference. The increase in average weight from pre- to post-holidays was greater for those attending the school with limited opportunities to sleep longer. Participants reported greater food intake during the holidays compared to school days and greater physical activity levels on weekends compared to school days, and school days compared to holidays. Results suggest that time of day preference may impact growth, with evening types who cannot sleep in growing at a slower rate

  12. Observation of Significant enhancement in the efficiency of a DSSC by InN nanoparticles over TiO 2-nanoparticle films

    2011-06-01

    We have studied the effect of InN deposited over TiO2 nanoparticle (NP) films on the performance of dye-sensitized solar cells (DSSCs) using N3 dye with I/I3- electrolyte. A 10-20% increase in efficiency was observed for InN deposited, N3 sensitized 5-8.5 μm thick TiO2 films as compared to similar non-treated films. The deposition of InN was carried out in the temperature range of 573-723 K organometallic chemical vapor deposition (OMCVD). Spectral shifts and DFT calculations with a model anchoring group (R‧COOH) both suggest binding of the N3 dye directly to both InN and the InN/TiO2 sites.

  13. Investigation of the near-surface structures of polar InN films by chemical-state-discriminated hard X-ray photoelectron diffraction

    2013-01-01

    Near-surface structures of polar InN films were investigated by laboratory-based hard X-ray photoelectron diffraction (HXPD) with chemical-state-discrimination. HXPD patterns from In 3d 5/2 and N 1s core levels of the In-polar and N-polar InN films were different from each other and compared with the simulation results using a multiple-scattering cluster model. It was found that the near-surface structure of the In-polar InN film was close to the ideal wurtzite structure. On the other hand, on the N-polar InN film, defects-rich surface was formed. In addition, the existence of the In-polar domains was observed in the HXPD patterns.

  14. Observation of complete oxidation of InN to In2O3 in air at elevated temperatures by using X-ray photoemission spectroscopy

    2006-01-01

    We present here an X-ray photoemission spectroscopy (XPS) analysis of a polycrystalline InN film on sapphire. The InN was completely oxidized to bixbyite in air after annealing at high temperatures. The analysis of the X-ray diffraction data demonstrated that the oxidation process started around 450 .deg. C. The high-resolution XPS data showed the In3d peaks and the N1s main peak located near 396.4 eV for the InN films. After oxidation, the N1s peak had completely disappeared while the In3d peaks had not changed. These results strongly indicate that the oxidation transformed the structure of InN film to In 2 O 3 .

  15. Role of dislocations and carrier concentration in limiting the electron mobility of InN films grown by plasma assisted molecular beam epitaxy

    Tangi, Malleswararao; De, Arpan; Shivaprasad, S. M.

    2018-01-01

    We report the molecular beam epitaxy growth of device quality InN films on GaN epilayer and nano-wall network (NWN) templates deposited on c-sapphire by varying the film thickness up to 1 μm. The careful experiments are directed towards obtaining high mobility InN layers having a low band gap with improved crystal quality. The dislocation density is quantified by using high resolution X-ray diffraction rocking curve broadening values of symmetric and asymmetric reflections, respectively. We observe that the dislocation density of the InN films grown on GaN NWN is less than that of the films grown on the GaN epilayer. This is attributed to the nanoepitaxial lateral overlayer growth (ELOG) process, where the presence of voids at the interface of InN/GaN NWN prevents the propagation of dislocation lines into the InN epilayers, thereby causing less defects in the overgrown InN films. Thus, this new adaptation of the nano-ELOG growth process enables us to prepare InN layers with high electron mobility. The obtained electron mobility of 2121 cm2/Vs for 1 μm thick InN/GaN NWN is comparable with the literature values of similar thickness InN films. Furthermore, in order to understand the reasons that limit electron mobility, the charge neutrality condition is employed to study the variation of electron mobility as a function of dislocation density and carrier concentration. Overall, this study provides a route to attaining improved crystal quality and electronic properties of InN films.

    Tyrosine kinase inhibitor (TKI) therapy in metastatic renal-cell carcinoma (mRCC) is noncurative and may be associated with significant toxicities. Some patients may receive treatment breaks as a result of TKI-related adverse effects or planned drug holidays. In this retrospective study, mRCC patients who underwent drug holidays during TKI therapy at 2 different institutions were analyzed. A drug holiday was defined as a period of drug cessation for ≥ 3 months for reasons other than progressive disease. Of the 112 patients, the median duration of the first drug holiday for the overall cohort was 16.8 months (95% confidence interval, 12.5-26.4), and 40 patients (36%) remain on the first drug holiday. Overall, patients received a median of 2 lines of treatment. Complete response before the initial drug holiday (n = 14) was associated with a longer surveillance period (P = .0004). The observed median survival of this cohort was 71.7 months (range, 1.3 to 93+ months). Some selected mRCC patients with a favorable response to TKIs may be eligible for drug holidays. The cohort evaluated in this retrospective study represents a highly selected group of patients with indolent disease biology. Copyright © 2018 Elsevier Inc. All rights reserved.

    Cubic InN films have been grown on MgO substrates with HfN buffer layers by pulsed laser deposition (PLD). It has been found that the use of HfN (100) buffer layers allows us to grow cubic InN (100) films with an in-plane epitaxial relationship of [001] InN //[001] HfN //[001] MgO . X-ray diffraction and electron back-scattered diffraction measurements have revealed that the phase purity of the cubic InN films was as high as 99%, which can be attributed to the use of HfN buffer layers and the enhanced surface migration of the film precursors by the use of PLD. - Graphical abstract: Cubic InN films have been grown on MgO substrates with HfN buffer layers by pulsed laser deposition (PLD).

  19. Photomodulated reflectance study on optical property of InN thin films grown by reactive gas-timing rf magnetron sputtering

    Porntheeraphat, S.; Nukeaw, J.

    2008-01-01

    The photoreflectance (PR) spectroscopy has been applied to investigate the band-gap energy (E g ) of indium nitride (InN) thin films grown by rf magnetron sputtering. A novel reactive gas-timing technique applied for the sputtering process has been successfully employed to grow InN thin films without neither substrate heating nor post annealing. The X-ray diffraction (XRD) patterns exhibit strong peaks in the orientation along (0 0 2) and (1 0 1) planes, corresponding to the polycrystalline hexagonal-InN structure. The band-gap transition energy of InN was determined by fitting the PR spectra to a theoretical line shape. The PR results show the band-gap energy at 1.18 eV for hexagonal-InN thin films deposited at the rf powers of 100 and 200 W. The high rf sputtering powers in combination with the gas-timing technique should lead to a high concentration of highly excited nitrogen ions in the plasma, which enables the formation of InN without substrate heating. Auger electron spectroscopy (AES) measurements further reveal traces of oxygen in these InN films. This should explain the elevated band-gap energy, in reference to the band-gap value of 0.7 eV for pristine InN films

  20. Electrical properties of cubic InN and GaN epitaxial layers as a function of temperature

    Fernandez, J.R.L.; Chitta, V.A.; Abramof, E.

    2000-01-01

    Carrier concentration and mobility were measured for intrinsic cubic InN and GaN, and for Si-doped cubic GaN as a function of temperature. Metallic n-type conductivity was found for the InN, while background p-type conductivity was observed for the intrinsic GaN layer. Doping the cubic GaN with Si two regimes were observed. For low Si-doping concentrations, the samples remain p-type. Increasing the Si-doping level, the background acceptors are compensated and the samples became highly degenerated n-type. From the carrier concentration dependence on temperature, the activation energy of the donor and acceptor levels was determined. Attempts were made to determine the scattering mechanisms responsible for the behavior of the mobility as a function of temperature

  1. A trade-off relation between tilt and twist angle fluctuations in InN grown by RF-MBE

    Hashimoto, A.; Iwao, K.; Yamamoto, A.

    2008-01-01

    In the InN growth on sapphire substrates, it is difficult to control both of tilt and twist angle fluctuations at same time. It is necessary to understand initial growth stage such as the role of nitridation process to improve the mosaicity. Low-temperature nitridation technique brings the drastically improvement of the tilt angle fluctuation, although the twist angle fluctuation becomes worse. Such experimental results strongly indicate that there is some trade-off relation between the tilt and the twist angle fluctuations as a function of the nitridation condition such as the nitridation time. In this paper, we discuss about such trade-off relation in the direct growth of InN on the nitridation sapphire substrates and also propose a simple model of initial nitridation process to explain it.

    2011-01-01

    One of the scientific challenges of growing InN quantum dots (QDs), using Molecular beam epitaxy (MBE), is to understand the fundamental processes that control the morphology and distribution of QDs. A systematic manipulation of the morphology, optical emission, and structural properties of InN/Si (111) QDs is demonstrated by changing the growth kinetics parameters such as flux rate and growth time. Due to the large lattice mismatch, between InN and Si (∼8%), the dots formed from the Strannski–Krastanow (S–K) growth mode are dislocated. Despite the variations in strain (residual) and the shape, both the dot size and pair separation distribution show the scaling behavior. We observed that the distribution of dot sizes, for samples grown under varying conditions, follow the scaling function.

  5. X-ray diffraction study of A- plane non-polar InN epilayer grown by MOCVD

    Moret, Matthieu; Briot, Olivier; Gil, Bernard

    2015-03-01

    Strong polarisation-induced electric fields in C-plane oriented nitrides semiconductor layers reduce the performance of devices. Eliminating the polarization fields can be achieved by growing nitrides along non polar direction. We have grown non polar A-plane oriented InN on R-plane (1‾102) nitridated sapphire substrate by MOCVD. We have studied the structural anisotropy observed in these layers by analyzing High Resolution XRay Diffraction rocking curve (RC) experiments as a function of the in-plane beam orientation. A-plane InN epilayer have a unique epitaxial relationship on R-Plane sapphire and show a strong structural anisotropy. Full width at half maximum (FWHM) of the InN(11‾20) XRD RC values are contained between 44 and 81 Arcmin. FWHM is smaller when the diffraction occurs along the [0001] and the largest FWHM values, of the (11‾20) RC, are obtained when the diffraction occurs along the [1‾100] in-plane direction. Atomic Force Microscopy imaging revealed morphologies with well organized crystallites. The grains are structured along a unique crystallographic orientation of InN, leading to larger domains in this direction. This structural anisotropy can be, in first approximation, attributed to the difference in the domain sizes observed. XRD reciprocal space mappings (RSM) were performed in asymmetrical configuration on (13‾40) and (2‾202) diffraction plane. RSM are measured with a beam orientation corresponding to a maximal and a minimal width of the (11‾20) Rocking curves, respectively. A simple theoretical model is exposed to interpret the RSM. We concluded that the dominant contribution to the anisotropy is due to the scattering coherence length anisotropy present in our samples.

    We report a detailed study of the effect of deposition parameters on optical, structural, and morphological properties of InN films grown by reactive radio-frequency (RF) sputtering on GaN-on-sapphire templates in a pure nitrogen atmosphere. Deposition parameters under study are substrate temperature, RF power, and sputtering pressure. Wurtzite crystallographic structure with c-axis preferred growth orientation is confirmed by X-ray diffraction measurements. For the optimized deposition conditions, namely at a substrate temperature of 450 C and RF power of 30 W, InN films present a root-mean-square surface roughness as low as {proportional_to}0.4 nm, comparable to the underlying substrate. The apparent optical bandgap is estimated at 720 nm (1.7 eV) in all cases. However, the InN absorption band tail is strongly influenced by the sputtering pressure due to a change in the species of the plasma. (Copyright copyright 2011 WILEY-VCH Verlag GmbH and Co.

  9. Vertically integrated (Ga, In)N nanostructures for future single photon emitters operating in the telecommunication wavelength range

    Winden, A; Mikulics, M; Grützmacher, D; Hardtdegen, H

    2013-01-01

    Important technological steps are discussed and realized for future room-temperature operation of III-nitride single photon emitters. First, the growth technology of positioned single pyramidal InN nanostructures capped by Mg-doped GaN is presented. The optimization of their optical characteristics towards narrowband emission in the telecommunication wavelength range is demonstrated. In addition, a device concept and technology was developed so that the nanostructures became singularly addressable. It was found that the nanopyramids emit in the telecommunication wavelength range if their size is chosen appropriately. A p-GaN contacting layer was successfully produced as a cap to the InN pyramids and the top p-contact was achievable using an intrinsically conductive polymer PEDOT:PSS, allowing a 25% increase in light transmittance compared to standard Ni/Au contact technology. Single nanopyramids were successfully integrated into a high-frequency device layout. These decisive technology steps provide a promising route to electrically driven and room-temperature operating InN based single photon emitters in the telecommunication wavelength range. (paper)

    An indium nitride (InN) gas sensor of 10 nm in thickness has achieved detection limit of 0.4 ppm acetone. The sensor has a size of 1 mm by 2.5 mm, while its sensing area is 0.25 mm by 2 mm. Detection of such a low acetone concentration in exhaled breath could enable early diagnosis of diabetes for portable physiological applications. The ultrathin InN epilayer extensively enhances sensing sensitivity due to its strong electron accumulation on roughly 5–10 nm deep layers from the surface. Platinum as catalyst can increase output current signals by 2.5-fold (94 vs. 37.5 μA) as well as reduce response time by 8.4-fold (150 vs. 1,260 s) in comparison with bare InN. More, the effect of 3% oxygen consumption due to breath inhalation and exhalation on 2.4 ppm acetone gas detection was investigated, indicating that such an acetone concentration can be analyzed in air.

    Electron cyclotron resonance etch rates for GaN, InN, and AlN are reported as a function of temperature for Cl 2 /H 2 /CH 4 /Ar and Cl 2 /H 2 /Ar plasmas. Using Cl 2 /H 2 /CH 4 /Ar plasma chemistry, GaN etch rates remain relatively constant from 30 to 125 degree C and then increase to a maximum of 2340 A/min at 170 degree C. The InN etch rate decreases monotonically from 30 to 150 degree C and then rapidly increases to a maximum of 2300 A/min at 170 degree C. This is the highest etch rate reported for this material. The AlN etch rate decreases throughout the temperature range studied with a maximum of 960 A/min at 30 degree C. When CH 4 is removed from the plasma chemistry, the GaN and InN etch rates are slightly lower, with less dramatic changes with temperature. The surface composition of the III--V nitrides remains unchanged after exposure to the Cl 2 /H 2 /CH 4 /Ar plasma over the temperatures studied

    An atmospheric pressure approach to growth of bulk group III-nitrides is outlined. Native III-nitride substrates for optoelectronic and high power, high frequency electronics are desirable to enhance performance and reliability of these devices; currently, these materials are available in research quantities only for GaN, and are unavailable in the case of InN. The thermodynamics and kinetics of the reactions associated with traditional crystal growth techniques place these activities on the extreme edges of experimental physics. The technique described herein relies on the production of the nitride precursor (N3-) by chemical and/or electrochemical methods in a molten halide salt. This nitride ion is then reacted with group III metals in such a manner as to form the bulk nitride material. The work performed during the period of funding (July 2004-September 2005) focused on the initial measurement of the solubility of GaN in molten LiCl as a function of temperature, the construction of electrochemical cells, the modification of a commercial glove box (required for handling very hygroscopic LiCl), and on securing intellectual property for the technique.

  14. Hole transport and photoluminescence in Mg-doped InN

    Hole conductivity and photoluminescence were studied in Mg-doped InN films grown by molecular beam epitaxy. Because surface electron accumulation interferes with carrier type determination by electrical measurements, the nature of the majority carriers in the bulk of the films was determined using thermopower measurements. Mg concentrations in a"window" from ca. 3 x 1017 to 1 x 1019 cm-3 produce hole-conducting, p-type films as evidenced by a positive Seebeck coecient. This conclusion is supported by electrolyte-based capacitance voltage measurements and by changes in the overall mobility observed by Hall effect, both of which are consistent with a change from surface accumulation on an n-type film to surface inversion on a p-type film. The observed Seebeck coefficients are understood in terms of a parallel conduction model with contributions from surface and bulk regions. In partially compensated films with Mg concentrations below the window region, two peaks are observed in photoluminescence at 672 meV and at 603 meV. They are attributed to band-to-band and band-to-acceptor transitions, respectively, and an acceptor binding energy of ~;;70 meV is deduced. In hole-conducting films with Mg concentrations in the window region, no photoluminescence is observed; this is attributed to electron trapping by deep states which are empty for Fermi levels close to the valence band edge.

  15. Retrospective forecasts of the upcoming winter season snow accumulation in the Inn headwaters (European Alps)

    Förster, Kristian; Hanzer, Florian; Stoll, Elena; Scaife, Adam A.; MacLachlan, Craig; Schöber, Johannes; Huttenlau, Matthias; Achleitner, Stefan; Strasser, Ulrich

    This article presents analyses of retrospective seasonal forecasts of snow accumulation. Re-forecasts with 4 months' lead time from two coupled atmosphere-ocean general circulation models (NCEP CFSv2 and MetOffice GloSea5) drive the Alpine Water balance and Runoff Estimation model (AWARE) in order to predict mid-winter snow accumulation in the Inn headwaters. As snowpack is hydrological storage that evolves during the winter season, it is strongly dependent on precipitation totals of the previous months. Climate model (CM) predictions of precipitation totals integrated from November to February (NDJF) compare reasonably well with observations. Even though predictions for precipitation may not be significantly more skilful than for temperature, the predictive skill achieved for precipitation is retained in subsequent water balance simulations when snow water equivalent (SWE) in February is considered. Given the AWARE simulations driven by observed meteorological fields as a benchmark for SWE analyses, the correlation achieved using GloSea5-AWARE SWE predictions is r = 0.57. The tendency of SWE anomalies (i.e. the sign of anomalies) is correctly predicted in 11 of 13 years. For CFSv2-AWARE, the corresponding values are r = 0.28 and 7 of 13 years. The results suggest that some seasonal prediction of hydrological model storage tendencies in parts of Europe is possible.

    2006-01-01

    Full text: The goal of the INNOX field campaign, which took place during January and February 2006 near the town of Schwaz, was to obtain a three-dimensional picture of the spatial distribution of air pollutants in the Inn Valley during wintertime. For this purpose continuous ground based measurements and, on six chosen days, vertical profiles within the lowest 200 m above ground level (AGL) of the valley atmosphere of certain VOCs (benzene, toluene, etc.) and CO were performed using a proton-transfer-reaction mass spectrometry instrument (PTR-MS). For the soundings a 200-m long teflon line was fixed on a tethered balloon through which the air was sucked to the PTR-MS instrument and to a CO analyser. Next to the inlet on the tethered balloon meteorological data, such as air temperature, pressure, wind, were measured as well. Above the lowest 200 m AGL a research aircraft from MetAir AG (Switzerland), equipped with various instruments for in-situ measurements of air pollutants and meteorological data, was operated. A typical flight pattern consisted of five vertical cross sections between about 150 to 2500 m AGL and lasted about three hours. Altogether 25 hours of aircraft measurements were carried out on six different days. The combination of low-level balloon measurements and upper-level aircraft observations yields vertical profiles of various parameters which cover the whole valley atmosphere. Preliminary results which show strong vertical but also horizontal gradients of air pollutant concentrations will be presented. (author)

  17. Evaluation of testing strategies for the radiation tolerant ATLAS n **+-in-n pixel sensor

    Klaiber Lodewigs, Jonas M

    2003-01-01

    The development of particle tracker systems for high fluence environments in new high-energy physics experiments raises new challenges for the development, manufacturing and reliable testing of radiation tolerant components. The ATLAS pixel detector for use at the LHC, CERN, is designed to cover an active sensor area of 1.8 m**2 with 1.1 multiplied by 10 **8 read-out channels usable for a particle fluence up to 10 **1**5 cm**-**2 (1 MeV neutron equivalent) and an ionization dose up to 500 kGy of mainly charged hadron radiation. To cope with such a harsh environment the ATLAS Pixel Collaboration has developed a radiation hard n **+-in-n silicon pixel cell design with a standard cell size of 50 multiplied by 400 mum**2. Using this design on an oxygenated silicon substrate, sensor production has started in 2001. This contribution describes results gained during the development of testing procedures of the ATLAS pixel sensor and evaluates quality assurance procedures regarding their relevance for detector operati...

  18. Panel Analysis of Internet Booking of Travel and Holiday Accommodation Indicators

    2016-01-01

    Full Text Available In the article four development indicators have been carefully selected and their impact on the level of acceptance of the Internet booking of travel and holiday accommodation in selected European countries has been observed. The statistical panel analysis approach was used to determine the individual and the common impact of the development indicators. The analysis has shown that an individual’s wealth, the public expenditure on education, and the Internet penetration rate have a positive statistically significant impact on the level of acceptance of the Internet booking of travel and holiday accommodation whereas the share of individuals with low level Internet skills has a negative statistically significant impact. These results carry significant importance for economists, politicians and all other stakeholders responsible for tourism development in a country. The use of the unbalanced panel is the main limitation of the article.

  5. Racism and the older voter? Arizona's rejection of a paid holiday to honor Martin Luther King.

    Kastenbaum, R

    1991-01-01

    Two propositions that would have established a paid Martin Luther King holiday were defeated in Arizona's statewide elections of November 6, 1990. Communities and counties with high proportions of senior adult voters cast proportionately more votes against these propositions. Was this an example of racism among the primarily anglo senior adult voters of Arizona? Three models were proposed to account for the general pattern of election-related behavior as well as the vote itself: 1) proactive racist, 2) pragmatic self-interest, and 3) fortress mentality. It was suggested that proactive racism and pragmatic self-interest accounted for less of the opposition to a paid holiday honoring Martin Luther King than did a fortress mentality that has developed through a combination of circumstances. Attention is also given to the larger question of senior adults as perpetrators as well as victims of bigotry.

  8. PRO-ENVIRONMENTAL BEHAVIORS IN THE HOUSEHOLD AND HOLIDAY SETTING. AN EXPLORATORY STUDY AMONG BRASOV CITIZENS

    ELENA-NICOLETA Untaru

    2015-06-01

    Full Text Available The present paper aims to investigate Brasov citizens’ pro-environmental behavior both in their household and holiday setting. In this sense, we conducted a qualitative research using the in-depth interview method on a 13 respondent sample which included self-declared environmentally friendly residents from the city of Brasov, Romania. Among them, six respondents are members of ecological NGOs and can be considered environmental activists. The interview guide was structured in two sections. First, we considered respondents' pro-environmental behaviors, the description of their activities, aimed at protecting the environment, as well as the tools and resources developed by public authorities in order to facilitate and stimulate citizens’ involvement in environmental protection. The second section was focused on the description of respondents’ last holiday, the choice of tourism destination, transportation, accommodation unit and activities in the destination; respondents’ pro-environmental behaviors; and the tools and instruments developed by local public authorities or hoteliers in order to facilitate tourists’ environmentally friendly behavior. The results of the present study outline the fact that respondents’ involvement in environmentally friendly activities is identical, or almost identical, in both household and holiday setting. For the environmental activists, such a behavior is difficult to change, even in a holiday setting, where environmental protection is one the individuals ‘priority’. The outcomes of our research can be used by both tourist services providers in order to adapt their offer to consumers’ pro-environmental behavior and local authorities who can identify the actions which have to be undertaken in order to facilitate such behavior.

  13. State Patty's Day: College Student Drinking and Local Crime Increased on a Student-constructed Holiday.

    Lefkowitz, Eva S; Patrick, Megan E; Morgan, Nicole R; Bezemer, Denille H; Vasilenko, Sara A

    2012-05-01

    College student alcohol consumption is a major concern, and is known to increase during the celebration of special events. This study examined a student-constructed holiday, State Patty's Day, at a university with a dominant drinking culture using three sources of data - coded data from Facebook groups, daily web surveys from first-year students (N= 227, 51% male, age 18 to 20; 27.3% Hispanic/Latino; of non-Hispanic/Latino, 26.9% of sample European American/White, 19.4% Asian American/Hawaiian/Pacific Islander, 15.9% African American/Black, 10.6% more than one race), and criminal offense data from police records. Results indicated that messages about State Patty's Day on Facebook focused on drinking and social aspects of the holiday, such as the social context of drinking, a sense of belonging to a larger community, and the social norms of drinking. These messages were rarely about consequences and rarely negative. On State Patty's Day, 51% of students consumed alcohol, compared to 29% across other sampled weekend days. Students consumed more drinks (M = 8.2 [SD = 5.3] drinks per State Patty's Day drinker) and were more likely to engage in heavy drinking on State Patty's Day, after controlling for gender, drinking motives, and weekend, demonstrating the event-specific spike in heavy drinking associated with this holiday. The impact of this student-constructed holiday went beyond individual drinking behavior; alcohol-specific and other crime also peaked on State Patty's Day and the day after. Event-specific prevention strategies may be particularly important in addressing these spontaneous, quickly-constructed, and dynamic events.

  14. Valentine's day as the 8th March of transitional Serbia: Analysis of a (new? holiday

    Baćević Jana

    2007-01-01

    Full Text Available In this text, I examine the phenomenon of sudden occurrence and spreading of the symbols, products and practices related to St. Valentine's Day, in Belgrade, Serbia. Though this custom had never been a part of Serbian festivities, neither "traditional" nor modern, this year it was aggressively marketed in the capital. In order to understand this phenomenon, I look at a similar holiday from the not-sodistant socialist past: Women's Day, or March 8th. Previous researchers of this holiday have underlined its primarily demagogical or mythical function of obscuring the gender inequalities of socialist society through the celebration of, and emphasis on, the proclaimed social equality on all levels. By juxtaposing dominant characteristics of Women's Day and their corresponding ideological functions with the dominant characteristics of St. Valentine's, I point to the possible ideological functions of the latter. On the one hand, it transmits the message of love, romance and reciprocity, therefore obscuring the persistent gender inequalities; on the other, it serves a far less demagogical function of supporting both the market of partners and the market of goods. In the final conclusion, I state that the occurrence of Valentine's Day celebrations in modern-day Serbia can be primarily tied to the development of the market of goods, and the corresponding desire to achieve the European standard, at least in terms of consumerism. Whether this holiday marks a beginning of transition in the domain of personal, intimate relationships, however, remains yet to be seen.

  15. Optical characterization of free electron concentration in heteroepitaxial InN layers using Fourier transform infrared spectroscopy and a 2 × 2 transfer-matrix algebra

    Katsidis, C. C.; Ajagunna, A. O.; Georgakilas, A.

    2013-01-01

    Fourier Transform Infrared (FTIR) reflectance spectroscopy has been implemented as a non-destructive, non-invasive, tool for the optical characterization of a set of c-plane InN single heteroepitaxial layers spanning a wide range of thicknesses (30–2000 nm). The c-plane (0001) InN epilayers were grown by plasma-assisted molecular beam epitaxy (PAMBE) on GaN(0001) buffer layers which had been grown on Al 2 O 3 (0001) substrates. It is shown that for arbitrary multilayers with homogeneous anisotropic layers having their principal axes coincident with the laboratory coordinates, a 2 × 2 matrix algebra based on a general transfer-matrix method (GTMM) is adequate to interpret their optical response. Analysis of optical reflectance in the far and mid infrared spectral range has been found capable to discriminate between the bulk, the surface and interface contributions of free carriers in the InN epilayers revealing the existence of electron accumulation layers with carrier concentrations in mid 10 19 cm −3 at both the InN surface and the InN/GaN interface. The spectra could be fitted with a three-layer model, determining the different electron concentration and mobility values of the bulk and of the surface and the interface electron accumulation layers in the InN films. The variation of these values with increasing InN thickness could be also sensitively detected by the optical measurements. The comparison between the optically determined drift mobility and the Hall mobility of the thickest sample reveals a value of r H = 1.49 for the Hall factor of InN at a carrier concentration of 1.11 × 10 19 cm −3 at 300°Κ.

  16. Outcome of holiday and nonholiday admission patients with acute peptic ulcer bleeding: a real-world report from southern Taiwan.

    Recent findings suggest that patients admitted on the weekend with peptic ulcer bleeding might be at increased risk of adverse outcomes. However, other reports found that there was no "holiday effect." The purpose of this study was to determine if these findings hold true for a real-life Taiwanese medical gastroenterology practice. We reviewed the medical files of hospital admissions for patients with peptic ulcer bleeding who received initial endoscopic hemostasis between January 2009 and March 2011. A total of 744 patients were enrolled (nonholiday group, n = 615; holiday group, n = 129) after applying strict exclusion criteria. Holidays were defined as weekends and national holidays in Taiwan. Our results showed that there was no significant difference in baseline characteristics between the two groups. We also observed that, compared to the nonholiday group, patients in the holiday group received earlier endoscopy treatment (12.20 hours versus 16.68 hours, P = 0.005), needed less transfused blood (4.8 units versus 6.6 units, P = 0.02), shifted from intravenous to oral proton-pump inhibitors (PPIs) more quickly (5.3 days versus 6.9 days, P = 0.05), and had shorter hospital stays (13.05 days versus 17.36 days, P = 0.005). In the holiday and nonholiday groups, the rebleeding rates were 17.8% and 23.41% (P = 0.167), the mortality rates were 11.63% versus 13.66% (P = 0.537), and surgery was required in 2.11% versus 4.66% (P = 0.093), respectively. Patients who presented with peptic ulcer bleeding on holidays did not experience delayed endoscopy or increased adverse outcomes. In fact, patients who received endoscopic hemostasis on the holiday had shorter waiting times, needed less transfused blood, switched to oral PPIs quicker, and experienced shorter hospital stays.

    Food allergy has been shown to severely affect quality of life (QoL) in children and their families. The Anaphylaxis Campaign U.K. supports families with allergic children and as part of that support ran an activity holiday for those with food allergy. This study investigated the effectiveness of this activity holiday for reducing anxiety and improving QoL and food allergy management for these children. Measures were taken at baseline, at the start of the activity holiday, at the end of the holiday, at 3 and 6 months follow-up. Children (n = 24) completed a paediatric food allergy-specific QoL questionnaire (PFA-QL), a generic QoL questionnaire (PedsQL, the Spence Children's Anxiety Scale (SCAS) and the children's health locus of control (CHLC) scale at all stages of the study. There were significant improvements in social QoL, food allergy-specific QoL, total CHLC and internal locus of control scores over time (p > 0.05). There were significant decreases in powerful others locus of control, total anxiety and obsessive compulsive disorder scores (p holiday was of significant benefit to the children who took part, providing support for the need for activity holidays such as this for children with severe food allergy. Ways in which adaptive locus of control and improved quality of life can be facilitated need to be further explored. © 2013 John Wiley & Sons A/S. Published by Blackwell Publishing Ltd.

  18. Effects of a holiday week on urban soil CO2 flux: an intensive study in Xiamen, southeastern China

    Ye, H.; Wang, K.; Chen, F.

    2012-12-01

    To study the effects of a holiday period on urban soil CO2 flux, CO2 efflux from grassland soil in a traditional park in the city of Xiamen was measured hourly from 28th Sep to 11th Oct, a period that included China's National Day holiday week in 2009. The results of this study revealed that: a) The urban soil CO2 emissions were higher before and after the holiday week and lower during the National Day holiday reflecting changes in the traffic cycles; b) A diurnal cycle where the soil CO2 flux decreased from early morning to noon was associated with CO2 uptake by vegetation which strongly offset vehicle CO2 emissions. The soil CO2 flux increased from night to early morning, associated with reduced CO2 uptake by vegetation; c) During the National Day holiday week in 2009, lower rates of soil respiration were measured after Mid-Autumn Day than earlier in the week, and this was related to a reduced level of human activities and vehicle traffic, reducing the CO2 concentration in the air. Urban holidays have a clear effect on soil CO2 flux through the interactions between vehicle, visitor and vegetation CO2 emissions which indirectly control the use of carbon by plant roots, the rhizosphere and soil microorganisms. Consequently, appropriate traffic controls and tourism travel plans can have positive effects on the soil carbon store and may improve local air quality.

    2009-01-01

    The effects of growth temperature and V/III ratio on the InN initial nucleation of islands on the GaN (0 0 0 1) surface were investigated. It is found that InN nuclei density increases with decreasing growth temperature between 375 and 525 °C. At lower growth temperatures, InN thin films take the form of small and closely packed islands with diameters of less than 100 nm, whereas at elevated temperatures the InN islands can grow larger and well separated, approaching an equilibrium hexagonal shape due to enhanced surface diffusion of adatoms. At a given growth temperature of 500 °C, a controllable density and size of separated InN islands can be achieved by adjusting the V/III ratio. The larger islands lead to fewer defects when they are coalesced. Comparatively, the electrical properties of the films grown under higher V/III ratio are improved

    2016-10-01

    We report a female child from an Irish Traveller family presenting with severe intellectual disability, dysmorphic features, renal anomalies, dental caries and cyclical vomiting. Current health issues include global developmental delay, mild concentric left ventricular hypertrophy, dental malocclusion and caries and a single duplex left kidney. The proband and her mother also have multiple epiphyseal dysplasia. Whole-exome sequencing was performed to identify the underlying genetic cause. DNA from the proband was enriched with the Agilent Sure Select v5 Exon array and sequenced on an Illumina HiSeq. Rare homozygous variants were prioritized. Whole-exome sequencing identified three linked homozygous missense variants in THOC6 (c.298T>A, p.Trp100Arg; c.700G>C, p.Val234Leu; c.824G>A, p.Gly275Asp) as the likely cause of this child's intellectual disability syndrome, resulting in a molecular diagnosis of Beaulieu-Boycott-Innes syndrome (BBIS). This is the first report of BBIS in Europe. BBIS has been reported previously in two Hutterite families and one Saudi family. A review of all patients to date shows a relatively homogenous phenotype. Core clinical features include low birth weight with subsequent growth failure, short stature, intellectual disability with language delay, characteristic facies, renal anomalies and dental malocclusion with caries. Some patients also have cardiac defects. All patients show characteristic dysmorphic facial features including a tall forehead with high anterior hairline and deep-set eyes with upslanting palpebral fissures. The coexistence of intellectual disability together with these characteristic facies should provide a diagnostic clue for BBIS during patient evaluation.

  2. Systematic study on dynamic atomic layer epitaxy of InN on/in +c-GaN matrix and fabrication of fine-structure InN/GaN quantum wells: Role of high growth temperature

    2016-12-01

    The growth kinetics and properties of nominally 1-ML (monolayer)-thick InN wells on/in +c-GaN matrix fabricated using dynamic atomic layer epitaxy (D-ALEp) by plasma-assisted molecular beam epitaxy were systematically studied, with particular attention given to the effects of growth temperature. Attention was also given to how and where the ˜1-ML-thick InN layers were frozen or embedded on/in the +c-GaN matrix. The D-ALEp of InN on GaN was a two-stage process; in the 1st stage, an "In+N" bilayer/monolayer was formed on the GaN surface, while in the 2nd, this was capped by a GaN barrier layer. Each process was monitored in-situ using spectroscopic ellipsometry. The target growth temperature was above 620 °C and much higher than the upper critical epitaxy temperature of InN (˜500 °C). The "In+N" bilayer/monolayer tended to be an incommensurate phase, and the growth of InN layers was possible only when they were capped with a GaN layer. The InN layers could be coherently inserted into the GaN matrix under self-organizing and self-limiting epitaxy modes. The growth temperature was the most dominant growth parameter on both the growth process and the structure of the InN layers. Reflecting the inherent growth behavior of D-ALEp grown InN on/in +c-GaN at high growth temperature, the embedded InN layers in the GaN matrix were basically not full-ML in coverage, and the thickness of sheet-island-like InN layers was essentially either 1-ML or 2-ML. It was found that these InN layers tended to be frozen at the step edges on the GaN and around screw-type threading dislocations. The InN wells formed type-I band line-up heterostructures with GaN barriers, with exciton localization energies of about 300 and 500 meV at 15 K for the 1-ML and 2-ML InN wells, respectively.

  3. Theoretical investigation on structural stability of InN thin films on 3C-SiC(0 0 1)

    2008-01-01

    The structural stability of InN thin films on 3C-SiC(0 0 1) substrate is systematically investigated based on an empirical interatomic potential, which incorporates electrostatic energy due to covalent bond charges and ionic charges. The calculated energy differences among coherently grown 3C-InN(0 0 1), 3C-InN(0 0 1) with misfit dislocations (MDs), and 2H-InN(0 0 0 1) imply that the coherently grown 3C-InN(0 0 1) is stable when the film thickness is less than 7 monolayers (MLs) while 2H-InN(0 0 0 1) is stabilized for the thickness beyond 8 MLs. This is because InN layers in 2H-InN(0 0 0 1) are fully relaxed by one MD. The analysis of atomic configuration at the 3C-InN(0 0 1)/3C-SiC(0 0 1) interfaces reveals that the coordination number of interfacial atoms is quite different from that in the bulk region. Thus, 3C-InN(0 0 1) with MDs on 3C-SiC(0 0 1) is always metastable over entire range of film thickness, consistent with the successful fabrication of 2H-InN(0 0 0 1) on 3C-SiC(0 0 1) by the molecular beam epitaxy. These results suggest that the mismatch in atomic arrangements at the interface crucially affects the structural stability of InN thin films on 3C-SiC(0 0 1) substrate

    Previous studies indicate an increased short-term and long-term mortality from major cancer surgery performed towards the end of the working week or during the weekend. We hypothesised that the prognosis after major cancer surgery is also negatively influenced by surgery conducted during holiday periods. Population-based nationwide Swedish cohort study. Patients undergoing oesophagectomy for oesophageal cancer between 1987 and 2010. Among 1820 included patients, 206 (11.3%) and 373 (20.5%) patients were operated on during narrow and wide holiday periods, respectively. Narrow (7 weeks) and wide (14 weeks) Swedish holiday periods. 90-day all-cause, 5-year all-cause and 5-year disease-specific mortality. Narrow holiday period did not increase all-cause 90-day (HR=0.84, 95% CI 0.53 to 1.33), all-cause 5-year (HR=1.01, 95% CI 0.85 to 1.21) or disease-specific 5-year mortality (HR=1.04, 95% CI 0.87 to 1.26). Similarly, wide holiday period did not increase the risk of 90-day (HR=0.79, 95% CI 0.55 to 1.13), all-cause 5-year (HR=0.96, 95% CI 0.84 to 1.1) or disease-specific 5-year mortality (HR=1.03, 95% CI 0.89 to 1.19). No measurable effects of holiday periods on short-term or longer term mortality following surgery for oesophageal cancer were observed in this population-based study, indicating that an adequate surgical experience was maintained during holiday periods.

  5. Understanding and optimization of InN and high indium containing InGaN alloys by metal organic chemical vapor deposition

    Tuna, Oecal

    2013-01-01

    Among the III-nitride semiconductors (Ga,Al,In)N, InN is the most attractive one due to having the narrowest bandgap of 0.64 eV. The revision in the bandgap of InN makes the InGaN more important since one can cover the whole solar spectrum by only changing In composition in an InGaN layer. The comparison of quality of InN and InGaN layers grown using a metal organic chemical vapor deposition (MOCVD) and a molecular beam epitaxy (MBE) methods indicate that growth with MOCVD is the more challenging, again due to the high dissociation temperature of NH 3 relative to the low decomposition temperature of InN (560-570 C). However, there is significant interest in developing an MOCVD process for InN and InGaN growth since MOCVD technology is the technology currently in use for commercial fabrication of group III nitride thin films. This thesis is therefore focused on a study of MOCVD growth of n- and p-type InN and In-rich InGaN films with the goal of providing new information on the influence of growth conditions on the film properties. Initially, a detailed investigation of MOCVD of InN is given. It is shown that MOCVD growth parameters (growth temperature and V/III ratio) have impacts on the layer properties such as In droplet formation on the surface as well as on its electrical and optical properties. PAS is employed for point defect analyzation. It is shown that In vacancies isolated by nitrogen vacancies are the dominant vacancy-type positron traps in InN. A decrease in the N vacancy concentration in InN is observed as a result of the growth temperature increase from 500 to 550 C. This is an indication of a reduction of N vacancy concentration by enhancing NH 3 dissociation at high growth temperature. Results obtained from optical techniques (Raman and PL) are used to estimate the free carrier concentrations in InN. Electrical characterizations are also carried out using Hall measurements. Carrier concentration values obtained by these three techniques revealed a

    Room temperature polarized infrared reflectance technique is employed to study the optical properties of wurtzite InN epilayers on Si(111) grown by molecular beam expitaxy. The reflection spectra are compared to the calculated spectra generated based on the anisotropic dielectric function model. Good agreement between the measured and calculated spectra is obtained. From the fit of the experimental curve, the reststrahlen parameters at the center of Brillouin zone, the carrier concentration and mobility as well as the epilayers thicknesses are determined. The values of the carrier concentration and mobility are in good agreement with the results obtained from the Hall effects measurements.

  7. Effects of GaN capping on the structural and the optical properties of InN nanostructures grown by using MOCVD

    Sun, Yuanping; Cho, Yonghoon; Wang, Hui; Wang, Lili; Zhang, Shuming; Yang, Hui

    2010-01-01

    InN nanostructures with and without GaN capping layers were grown by using metal-organic chemical vapor deposition. Morphological, structural, and optical properties were systematically studied by using atomic force microscopy, X-ray diffraction (XRD) and temperature-dependent photoluminescence (PL). XRD results show that an InGaN structure is formed for the sample with a GaN capping layer, which will reduce the quality and the IR PL emission of the InN. The lower emission peak at ∼0.7 eV was theoretically fitted and assigned as the band edge emission of InN. Temperature-dependent PL shows a good quantum efficiency for the sample without a GaN capping layers; this corresponds to a lower density of dislocations and a small activation energy.

  8. Formation of InN atomic-size wires by simple N adsorption on the In/Si(111)–(4 × 1) surface

    Guerrero-Sánchez, J.; Takeuchi, Noboru

    2016-01-01

    Highlights: • N atoms on the surface form bonds with two In atoms and one Si atom. • Surface formation energy calculations show two stable structures with formation of InN atomic-size wires. • Projected density of states shows a tendency to form In−N and Si−N bonds on the surface. • Charge density corroborates the covalent character of the In−N bonds. - Abstract: We have carried out first principles total energy calculations to study the formation of InN atomic-size wires on the In/Si(111)–(4 × 1) surface. In its most favorable adsorption site, a single N atom forms InN arrangements. The deposit of 0.25 monolayers (MLs) of N atoms, result in the breaking of one of the original In chains and the formation of an InN atomic size wire. Increasing the coverage up to 0.5 ML of N atoms results in the formation of two of those wires. Calculated surface formation energies show that for N-poor conditions the most stable configuration is the original In/Si(111)–(4 × 1) surface with no N atoms. Increasing the N content, and in a reduced range of chemical potential, the formation of an InN wire is energetically favorable. Instead, from intermediate to N-rich conditions, two InN atomic wires are more stable. Projected density of states calculations have shown a trend to form covalent bonds between the In−p and N−p orbitals in these stable models.

    2013-01-01

    The structural and nanomechanical properties of InN films grown on Si(1 0 0) using femtosecond pulsed laser deposition were studied for different growth conditions. Atomic nitrogen was generated by either thermal cracking or laser-induced breakdown (LIB) of ammonia. Optical emission spectroscopy was conducted on the laser plasma and used to observe atomic nitrogen formation. An indium buffer layer was initially grown on the Si substrate at low temperature. The surface structure and morphology were investigated by in situ reflection high-energy electron diffraction, ex situ atomic force microscopy and x-ray diffraction (XRD). The results show that the initial buffer indium layers were terminated with the In(2 × 1) structure and had a smooth surface. With increased coverage, the growth mode developed from two-dimensional layers to three-dimensional islands. At room temperature (RT), formation of submicrometre islands resulted in mixed crystal structure of In and InN. As the substrate temperature was increased to 250–350 °C, the crystal structure was found to be dominated by fewer In and more InN, with only InN formed at 350 °C. The XRD patterns show that the grown InN films have wurtzite crystal structure. The film hardness near the surface was observed to increase from less than 1 GPa, characteristic of In for the sample grown at RT using the thermal cracker, to a hardness of 11 GPa at 30 nm from surface, characteristic of InN for samples grown at 350 °C by LIB. The hardness at deep indents reaches the hardness of the Si substrate of ∼12 GPa. (paper)

  10. Tourism as a form of social intervention: the Holiday Participation Centre in Flanders

    2009-09-01

    Full Text Available This article presents the concept of social tourism as a form of social intervention. Tourism is seen by the European Economic and Social Committee as an opportunity for relation building, personal development and social integration. Social tourism initiatives offer holiday opportunities for persons who are otherwise prohibited from taking holidays, because of emotional, financial or health reasons. These mostly take the form of domestic breaks or day trips. In several countries of mainland Europe, the public sector supports these initiatives via involvement in public-private partnerships. One of these partnerships is the Holiday Participation Centre in Flanders, Belgium. This article will frame the initiative within social tourism provision in Flanders, Belgium, present the basic principles upon which the system operates, and give an overview of quantitative research findings regarding its outcomes as a form of social intervention. In dit artikel wordt sociaal toerisme gepresenteerd als een sociale interventie. Het Europees Economisch en Sociaal Comité beschouwt toerisme als een middel tot het opbouwen van netwerken, persoonlijke ontwikkeling en sociale integratie. Mensen die normaliter door emotionele, financiële of gezondheidsredenen niet op vakantie kunnen, worden door sociaal toerisme in staat gesteld wel op vakantie te gaan. Dit sociaal toerisme heeft veelal de vorm van dagtripjes en binnenlandse vakanties. De publieke sector van diverse Europese landen ondersteunt deze initiatieven voor sociaal toerisme, en doet dat door publiek-private samenwerkingsverbanden op te richten. Een van deze samenwerkingsverbanden is het Steunpunt Vakantieparticipatie van Toerisme Vlaanderen, België. Dit artikel beschrijft een initiatief tot sociaal toerisme in Vlaanderen, presenteert de grondslagen van dergelijke initiatieven tot sociaal toerisme en geeft een overzicht van onderzoeksbevindingen naar het sociaal toerisme als sociale interventie.

    Full Text Available Abstract Background With the rapid increase in obesity rates, determining critical periods for weight gain and the effects of changes in fat mass is imperative. The purpose of this study was to examine changes in body weight and composition over the holiday season (Thanksgiving through New Year's in male and female college students. Methods Subjects completed three visits: the first occurred within 2 weeks prior to Thanksgiving, the second occurred within 5 to 7 days following Thanksgiving, and the third occurred within 10 days following New Year's Day. A total of 82 healthy male and female college age subjects participated. Body composition by dual energy x-ray absorptiometry (DXA was assessed at visits 1 and 3 while body weight was assessed at all three visits. Results Average body weight remained relatively unchanged from pre-Thanksgiving to post-New Year's (71.3 ± 14 kg vs. 71.2 ± 15 kg; P = 0.71 and, in fact, a subset of normal weight subjects lost a significant amount of body weight. However, percent body fat (25.9 ± 9 %fat vs. 27.0 ± 9 %fat; P P P = 0.08 was not significantly different than the post-New Year's. A significant positive relationship (P P Conclusion Despite the fact that body weight remained unchanged over the course of the holiday season, a significant increase in %body fat and fat mass was observed. With recent evidence showing marked morbidity and mortality to be associated with increased body fat (particularly abdominal adiposity, results from this study suggest body weight alone may underestimate the potentially deleterious effects of the holiday season.

    While chronobiological studies have reported seasonal variation in panic attacks (PA) episodes, information on the timing of PA by week-days may enable better understanding of the triggers of PA episodes and thereby provide pointers for suitable interventional approaches to minimize PA attacks. This study investigated weekly variation in potential PA admissions including associations with holidays using a population-based longitudinal, administrative claims-based dataset in an Asian population. This study used ambulatory care data from the "Longitudinal Health Insurance Database 2000. We identified 993 patients with panic disorder (PD), and they had 4228 emergency room (ER) admissions for potential PA in a 3-year period between 1 January 2009 and 31 December 2011. One-way analysis of variance (ANOVA) was used to examine associations between the potential PA admissions and holidays/weekend days/work-days of the week. The daily mean number of potential PA admissions was 3.96 (standard deviation 2.05). One-way ANOVA showed significant differences in potential PA admissions by holiday and day of the week (pholidays. Furthermore, the weekly variations were similar for females and males, although females always had higher potential PA admissions on both weekdays and holidays than the males. We found that potential PA admissions among persons with PD varied systematically by day of the week, with a significant peak on weekends and holidays.

    People with end-stage kidney disease receiving haemodialysis are restricted to holidays where dialysis services are readily available. Holiday dialysis in regional, rural and remote areas is particularly challenging. The aims of this study were to evaluate the wellbeing of those who received dialysis in a holiday haemodialysis bus and to measure patient well-being with that of a comparable cohort of haemodialysis patients. A three machine haemodialysis bus, the Big Red Kidney Bus, was built to enable people, their families and carers to take holidays across a range of tourist destinations in Victoria, Australia. Measures included pre-post subjective well-being, dialysis symptoms and mood questionnaires complemented by post semi-structured telephone interviews. Participating holidaymakers were positive about the haemodialysis bus service and the standard of care experienced. They reported decreased dialysis side effects of fatigue, muscle cramp and dry skin. The overall number of reported symptoms decreased, and the perceived level of bother associated with symptoms also decreased. No changes in subjective well-being and mood were detected. Mean Personal Wellbeing Index scores were significantly higher than in a comparative haemodialysis sample. The Big Red Kidney Bus provided a safe and feasible holiday dialysis service. Holidaymakers' well-being was reflected by the decreased dialysis patient side effects. © 2016 Asian Pacific Society of Nephrology.

    The Indian Gaming Regulatory Act, passed by Congress on October 17, 1988 provided tribes with the Federal statute to pursue gaming activities on tribal lands. Many Native communities contribute to larger regional economies and tourism industries. These casino facilities often include resort-style hotel amenities. Not surprisingly, they are also large consumers of energy, operating 24 hours a day and 7 days a week. Tribes with hotels and casinos can implement sustainable design features and not only receive economic gain, but also environmental and community benefits. The intention of this paper is to identify sustainable design opportunities at the Inn of the Mountain Gods Hotel and Casino. This research stems from previous work the researcher conducted and subsequently published for the Illinois Green Business Association. First, the paper reviews what sustainable design is and points of interest when considering sustainable construction. Next, the paper explores the precedents set by the Blue Lake Rancheria, Rincon Band of Luiseno Indians, and the Forest County Potawatomi Tribe. Then, the research examines areas to collect baseline information and identify opportunities in sustainable design for the Mescalero Apache Tribe, Inn of the Mountain Gods Hotel and Casino located in New Mexico. Lastly, the work explores the resources and funding options available to the tribe.

  18. Phase mapping of aging process in InN nanostructures: oxygen incorporation and the role of the zinc blende phase

    Gonzalez, D; Lozano, J G; Herrera, M; Morales, F M; GarcIa, R; Ruffenach, S; Briot, O

    2010-01-01

    Uncapped InN nanostructures undergo a deleterious natural aging process at ambient conditions by oxygen incorporation. The phases involved in this process and their localization is mapped by transmission electron microscopy (TEM)-related techniques. The parent wurtzite InN (InN-w) phase disappears from the surface and gradually forms a highly textured cubic layer that completely wraps up a InN-w nucleus which still remains from the original single-crystalline quantum dots. The good reticular relationships between the different crystals generate low misfit strains and explain the apparent easiness for phase transformations at room temperature and pressure conditions, but also disable the classical methods to identify phases and grains from TEM images. The application of the geometrical phase algorithm in order to form numerical moire mappings and RGB multilayered image reconstructions allows us to discern among the different phases and grains formed inside these nanostructures. Samples aged for shorter times reveal the presence of metastable InN:O zinc blende (zb) volumes, which act as the intermediate phase between the initial InN-w and the most stable cubic In 2 O 3 end phase. These cubic phases are highly twinned with a proportion of 50:50 between both orientations. We suggest that the existence of the intermediate InN:O-zb phase should be seriously considered to understand the reason for the widely scattered reported fundamental properties of thought to be InN-w, as its bandgap or superconductivity.

  19. Heteroepitaxial growth of In-face InN on GaN (0001) by plasma-assisted molecular-beam epitaxy

    The thermodynamic aspects of indium-face InN growth by radio frequency plasma-assisted molecular-beam epitaxy (rf-MBE) and the nucleation of InN on gallium-face GaN (0001) surface were investigated. The rates of InN decomposition and indium desorption from the surface were measured in situ using reflected high-energy electron diffraction and the rf-MBE 'growth window' of In-face InN (0001) was identified. It is shown that sustainable growth can be achieved only when the arrival rate of active nitrogen species on the surface is higher than the arrival rate of indium atoms. The maximum substrate temperature permitting InN growth as a function of the active nitrogen flux was determined. The growth mode of InN on Ga-face GaN (0001) surface was investigated by reflected high-energy electron diffraction and atomic force microscopy. It was found to be of the Volmer-Weber-type for substrate temperatures less than 350 deg. C and of the Stranski-Krastanov for substrate temperatures between 350 and 520 deg. C. The number of monolayers of initial two-dimensional growth, in the case of Stranski-Krastanov mode, varies monotonically with substrate temperature, from 2 ML at 400 deg. C to about 12 ML at 500 deg. C. The evolution and coalescence of nucleated islands were also investigated as a function of substrate temperature. It was found that at higher temperature their coalescence is inhibited leading to porous-columnar InN thin films, which exhibit growth rates higher than the nominal value. Therefore, in order to achieve continuous InN layers on GaN (0001) a two-step growth approach is introduced. In that approach, InN is nucleated at low temperatures on GaN and the growth continues until full coalescence of the nucleated islands. Subsequently, this nucleation layer is overgrown at higher substrate temperature in order to achieve high-quality continuous films. The InN films grown by the two-step method were investigated by x-ray diffraction, Hall-effect measurements, and

    comprehensively researched. However, other travel domains (e.g., occasional weekend trips or holidays) have only recently received more attention, despite their environmental impact. The paper investigates whether and how daily travel patterns (‘modality styles’) correspond with non-daily travel behaviour...... in the commuter belt of Greater Copenhagen in spring 2016. First, we identify ‘modality styles’ by grouping the sample based on the respondents’ daily mode choices. Second, we relate the identified modality styles to socio-economic and socio-demographic factors, frequency and mode choice of longer weekend trips...... and holidays, and travel-related attitudes. The results reveal that the urban structure of a residential location (e.g., urban vs. peri-urban) exerts to some extent influence on the constitution of daily modality styles. We found, furthermore, a tendency for more weekend trips and holidays among the urban...

  1. Influence of human population movements on urban climate of Beijing during the Chinese New Year holiday

    Zhang, Jingyong; Wu, Lingyun

    2017-03-01

    The population movements for the Chinese New Year (CNY) celebrations, known as the world’s largest yearly migration of human beings, have grown rapidly in the past several decades. The massive population outflows from urban areas largely reduce anthropogenic heat release and modify some other processes, and may thus have noticeable impacts on urban climate of large cities in China. Here, we use Beijing as an example to present observational evidence for such impacts over the period of 1990-2014. Our results show a significant cooling trend of up to 0.55 °C per decade, particularly at the nighttime during the CNY holiday relative to the background period. The average nighttime cooling effect during 2005-2014 reaches 0.94 °C relative to the 1990s, significant at the 99% confidence level. The further analysis supports that the cooling during the CNY holiday is attributable primarily to the population outflow of Beijing. These findings illustrate the importance of population movements in influencing urban climate despite certain limitations. As the world is becoming more mobile and increasingly urban, more efforts are called for to understand the role of human mobility at various spatial and temporal scales.

  2. Comparison of Climate Preferences for Domestic and International Beach Holidays: A Case Study of Canadian Travelers

    2016-02-01

    Full Text Available Coastal tourism is the largest segment of global leisure tourism and it is firmly linked to the destination’s natural resources—with climatic resources chief among them. Through observations and survey responses of beach users, studies have evaluated climatic resources for coastal tourism by quantifying optimal and unacceptable conditions. However, these studies have not taken into consideration that different forms of holidays (e.g., daytrips, short trips, main annual holiday, “once-in-a-lifetime” trip may have varying degrees of resilience to climatic conditions. This is the first study to explore whether ideal and unacceptable climatic conditions vary between domestic and international tourists. Using an in situ survey, Canadian beach users traveling domestically (n = 359 and internationally (n = 120 were examined. Key findings include statistically significant differences (p ≤ 0.05 between the two sample groups for every climate variable, with the international sample more resilient to a broader range of weather conditions, including a greater acceptance for warm temperatures, longer rainfall durations, higher wind speeds, and greater cloud cover. This study adds further insight into the complexities of evaluating climate for tourism, with implications for the demand response of tourists to climate change.

    The winter break is a vital opportunity to leave behind the end-of-year workload stress, compounded by the rush to complete tasks in preparation of the year ahead, and focus on some genuine rest and recuperation. The challenges of 2015 can only be met if our batteries are correctly recharged: so full steam ahead for a holiday period devoted to a well earned rest and a crucial change of air and ideas!   The importance of restful holidays is a recognised downtime in all modern democracies. This is needed to overcome the work-related stress that is a growing problem in today’s work environment by ensuring the rest and recuperation that is necessary for the wellbeing of all personnel. In the field of information technology, experts know that machines would not work without “WMS”, which stands for “Workload Management Service”. Things can go very differently when instead of “jobs” for computers we talk of “tasks&r...

  5. Eco-efficiency of holiday homes; Vapaa-ajan asumisen ekotehokkuus

    Rytkoenen, A.; Kirkkari, A.-M. (eds.) (Work Efficiency Inst., Rajamaeki (Finland))

    2010-03-15

    The study is part of the Environmental Cluster Research Programme of the Ministry of the Environment and was done by seven research institutes. The study examined holiday homes in terms of their potential for enhancing sustainable consumption and eco-efficiency. The research focused on: constant heating and frost-proof plumbing, their acceptability, use of services and future needs, the operating requirements for home appliances, travel to cottages, and their macroeconomic effects. Next to construction and repair services summer cottage owners were interested in improvement of transport and health care services, telecommuting and the installation of constant heating systems and frost-proof plumbing. As of 2008, there were approximately 478,000 summer cottages. Each year, 4,000 new cottages are built, while 3,000 old cottages are extended, repaired and partly rebuilt so that they are almost like new buildings. Approximately 76 percent of all cottages are connected to the power grid. Just under one-third of all cottages are fitted for year-round use. Raising the level of cottage amenities increases their utilisation rate and energy consumption. Traditional, primarily summer-use cottages with wood-burning heat, bucket-drawn water and dry toilets are eco-efficient. Heating and travelling to cottages are the largest consumers of energy in cottage living. Travelling to cottages consumes approximately 1,070 GWh per year. The more that various electric appliances are used in the cottages and the more comfortable they become, the more often they are visited also during winter time and the higher are the energy and emission bills. Traffic to the holiday homes increases also because of growing mean distances between peopleAEs main residences and cottages and because of increased visits to friendsAE and relativesAE cottages and to rented holiday housing in Lapland and elsewhere. In 2005 total cottage electricity consumption was approximately 900 GWh/year. The average

    Both anthropogenic emission and synoptic conditions play important roles in ozone (O3) formation and accumulation. In order to understand the influence of synoptic condition and holiday effects on ozone production in the Yangtze River Delta region, China, concentrations of speciated volatile organic compounds (VOCs) and O3 as well as other relevant trace gases were simultaneously measured at the Station for Observing Regional Processes of the Earth System (SORPES) in Nanjing around the National Day holidays of China in 2014, which featured substantial change of emissions and dominated by typical anti-cyclones. Different groups of VOC species and their chemical reactivities were comprehensively analyzed. We observed clear diurnal variations of short alkenes during the measurement period, considerable amount of short alkenes were observed during night (more than 10 ppb) while almost no alkenes were measured during daytime, which might be attributed to different chemical processes. The obvious enhancement of the VOC tracers during the National Day holidays (Oct. 1st-Oct. 7th) indicated that the holiday effect strongly influenced the distribution of VOC profile and chemical reactivity in the atmosphere. At the same time, two meso-scale anticyclone processes were also observed during the measurement period. The synoptic condition contributed to the accumulation of VOCs and other precursors, which consequently impacted the ozone production in this region. The integrated influence of synoptic and holiday effects was also analyzed with an Observation Based Model (OBM) based on simplified MCM (Master Chemical Mechanism) chemical mechanism. The calculated relative increment reactivity (RIR) of different VOC groups revealed that during the holidays, this region was in VOC-limited regime and the variation of RIR shows a close linkage to the development and elimination of anti-cyclones, indicating an in-negligible contribution of synoptic effect toward ozone production in this

    Long patient waiting time and congestion is a major problem faced by Green Zone in Emergency Department at Hospital Universiti Sains Malaysia (EDHUSM) especially during weekends and public holidays. Even though the Green Zone is servicing only the non-critical patients, patient waiting time, causing the department fails to achieve its Key Performance Indicator (KPI). The long waiting time is due to the insufficient resources provided during the weekends and public holidays versus the large number of patients. Currently, only two doctors supported by two nurses are scheduled for every shift during weekends and public holidays. The numbers of patients are higher during weekends and public holidays as compared to weekdays, but the scheduled number of doctors and nurses are the same as weekdays. Therefore, this study presents a hybrid method to estimate the right number of doctors and nurses for improving the services of the Green Zone during weekends and public holidays. Fifty scenarios based on current and proposed schedules of doctors and nurses are simulated and analysed using the hybrid method of Discrete Event Simulation (DES) and Data Envelopment Analysis (DEA). Banker, Charnes and Cooper (BCC) input-oriented model and Super-Efficiency models of DEA were used to analyse the efficiency of the scenarios. The results show that the best schedule is a combination of four doctors supported by four nurses in every shift during weekends and public holidays for the Green Zone. The findings show that such schedule will not only help the department to achieve its KPI but also enable a more optimal utilization of the resources.

    Networks of vertically c-oriented prism shaped InN nanowalls, are grown on c-GaN/sapphire templates using a CVD technique, where pure indium and ammonia are used as metal and nitrogen precursors. A systematic study of the growth, structural and electronic properties of these samples shows a preferential growth of the islands along [ 1 1 2 bar 0 ] and [0 0 0 1] directions leading to the formation of such a network structure, where the vertically [0 0 0 1] oriented tapered walls are laterally align along one of the three [ 1 1 2 bar 0 ] directions. Inclined facets of these walls are identified as semipolar (1 1 2 bar 2) -planes of wurtzite InN. Onset of absorption for these samples is observed to be higher than the band gap of InN suggesting a high background carrier concentration in this material. Study of the valence band edge through XPS indicates the formation of positive depletion regions below the surface of the side facets [(1 1 2 bar 2) -planes] of the walls. This is in contrast with the observation for c-plane InN epilayers, where electron accumulation is often reported below the top surface.

    2016-01-01

    The growth kinetics and structural perfection of (InN)_1/(GaN)_1_–_2_0 short-period superlattices (SPSs) were investigated with their application to ordered alloys in mind. The SPSs were grown on +c-GaN template at 650 °C by dynamic atomic layer epitaxy in conventional plasma-assisted molecular beam epitaxy. It was found that coherent structured InN/GaN SPSs could be fabricated when the thickness of the GaN barrier was 4 ML or above. Below 3 ML, the formation of SPSs was quite difficult owing to the increased strain in the SPS structure caused by the use of GaN as a template. The effective or average In composition of the (InN)_1/(GaN)_4 SPSs was around 10%, and the corresponding InN coverage in the ∼1 ML-thick InN wells was 50%. It was found that the effective InN coverage in ∼1 ML-thick InN wells could be varied with the growth conditions. In fact, the effective In composition could be increased up to 13.5%, i.e., the corresponding effective InN coverage was about 68%, by improving the capping/freezing speed by increasing the growth rate of the GaN barrier layer.

    The thermoelectric properties of indium nitride in the most stable wurtzite phase (w-InN) as a function of electron and hole concentrations and temperature were studied by solving the semiclassical Boltzmann transport equations in conjunction with ab initio electronic structure calculations, within Density Functional Theory. Based on maximally localized Wannier function basis set and the ab initio band energies, results for the Seebeck coefficient are presented and compared with available experimental data for n-type as well as p-type systems. Also, theoretical results for electric conductivity and power factor are presented. Most cases showed good agreement between the calculated properties and experimental data for w-InN unintentionally and p-type doped with magnesium. Our predictions for temperature and concentration dependences of electrical conductivity and power factor revealed a promising use of InN for intermediate and high temperature thermoelectric applications. The rigid band approach and constant scattering time approximation were utilized in the calculations.

    2015-05-01

    Full Text Available Growth of InN nanowires have been carried out on quartz substrates at different temperatures by vapor-liquid-solid (VLS technique using different thicknesses of Au catalyst layer. It has been found that a narrow window of Au layer thickness and growth temperature leads to multi-nucleation, in which each site acts as the origin of several nanowires. In this multi-nucleation regime, several tens of micrometer long wires with diameter as small as 20 nm are found to grow along [ 11 2 ̄ 0 ] direction (a-plane to form a dense network. Structural and electronic properties of these wires are studied. As grown nanowires show degenerate n-type behavior. Furthermore, x-ray photoemission study reveals an accumulation of electrons on the surface of these nanowires. Interestingly, the wire network shows persistence of photoconductivity for several hours after switching off the photoexcitation.

    We have grown hexagonal InN (h-InN) films on 3C-SiC (001) substrates by RF-N 2 plasma molecular beam epitaxy taking account of small lattice mismatch between h-InN (10-10) and 3C-SiC (110). It was found from X-ray diffraction (XRD) measurements that h-InN grows with h-InN (0001) vertical stroke vertical stroke 3C-SiC (001) and h-InN (1-100) vertical stroke vertical stroke 3C-SiC (110). XRD measurements also revealed that the h-InN epitaxial layers grown on 3C-SiC (001) are composed of single domain. Strong and sharp photoluminescence from the h-InN was clearly observed at around 0.69 eV. (copyright 2005 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim) (orig.)

  19. Hypothesis: holiday sudden cardiac death: food and alcohol inhibition of SULT1A enzymes as a precipitant.

    Eagle, Ken

    2012-10-01

    Sudden cardiac death is a significant health issue, causing millions of deaths worldwide annually. Studies have found that the likelihood of such death is higher in winter. Further studies identified that the highest likelihood occurs on Christmas Day and New Years Day, but not the interim period. Thanksgiving, Independence Day and the Islamic holiday Eid Al-Fitr also show significant increases in the rate of cardiac events or death. A number of mechanisms have been proposed, but none have satisfactorily explained the evidence. This article reviews the data supporting the existence of a holiday cardiac death phenomenon, the involvement of catecholamines and the normal modes of human catecholamine deactivation. Further evidence is reviewed that supports a hypothesized mechanism whereby critical SULT1A catecholamine deactivation enzymes can in some patients be inhibited by naturally-occurring phenols and polyphenols in foods and alcohols. If deactivation is inhibited by holiday consumption excesses, holiday stress or excitement could lead to a buildup of catecholamines that can cause fatal arrhythmias. Awareness of this mechanism could reduce deaths, both through doctor/patient education leading to a moderation in consumption and through the potential identification of patients with a predisposition to SULT1A inhibition. This hypothesis also raises parallels between sudden cardiac death in adults and Sudden Infant Death Syndrome (SIDS). The possible involvement of SULT1A inhibition in SIDS is discussed.

    2015-04-01

    School closure is one of the most common interventions in the early weeks of an influenza pandemic. Few studies have investigated social contact patterns and compared individual student contact characteristics during the school term and holiday periods in Taiwan. Here, we conducted a well-used questionnaire survey in a junior high school (grades 7-8) in June 2013. All 150 diary-based effective questionnaires covering conversation and skin-to-skin contact behaviour were surveyed. Two questionnaires for each participant were designed to investigate the individual-level difference of contact numbers per day during the two periods. The questionnaire response rate was 44%. The average number of contacts during term time (20·0 contacts per day) and holiday periods (12·6 contacts per day) were significantly different (P holiday periods, the number of contacts decreased by 40%. This study is the first research to investigate the contact numbers and contact characteristics for school-age children during the school term and a holiday period in Taiwan. With regard to public health, this study could provide the basic contact information and database for modelling influenza epidemics for minimizing the spread of influenza that depends on personal contacts for transmission.

  4. From charity and philanthropy to State social protection: school holiday camps in Spain (1887-1936

    Pedro L. MORENO MARTÍNEZ

    2013-11-01

    Full Text Available School holiday camps, which started in Switzerland in 1886, would start to function in Spain under the institutionalist and director of the then called Museo de Instrucción Primaria de Madrid (Museum of Primary Instruction, Manuel B. Cossío, in 1887. The paper analyses briefly the social, hygienic and educational context in which international movement of summer camps made their appearance and with special reference to Spain. The paper focuses on the beginnings and the scope of these camps in Spain and on the influence of public policies on these processes. These policies shifted from initial government inhibition and the call to the forces of the country to charity and patriotism, to a progressive promotion and to State protection for the summer camps.

    2013-01-01

    With this observation study we aimed to determine how and when sunscreen was used. 20 sun seekers were observed during a one-week sun holiday in Hurghada, Egypt. The sunscreen application thickness was related to part of body, time outdoors, exposure to ultraviolet radiation and to sunburning. Skin...... and the sunscreen application thickness was in average 0.79 mg cm(-)2 giving an approximated effect of SPF3. For different body parts either the total UVR exposure dose or the UVR exposure time and UVR exposure dose before the first sunscreen application were higher for sunburned than non-sunburned skin sites....... In the final model gender, skin type and UVR to skin (adjusted for SPF and sunscreen application thickness) were significant predictors of sunburning. The sunscreen application thickness of 0.79 mg cm(-)2 was less than the 2 mg cm(-2) used for testing SPF. The late start of sunscreen use and improper...

  6. Understanding and optimization of InN and high indium containing InGaN alloys by metal organic chemical vapor deposition

    Tuna, Oecal

    2013-07-18

    Among the III-nitride semiconductors (Ga,Al,In)N, InN is the most attractive one due to having the narrowest bandgap of 0.64 eV. The revision in the bandgap of InN makes the InGaN more important since one can cover the whole solar spectrum by only changing In composition in an InGaN layer. The comparison of quality of InN and InGaN layers grown using a metal organic chemical vapor deposition (MOCVD) and a molecular beam epitaxy (MBE) methods indicate that growth with MOCVD is the more challenging, again due to the high dissociation temperature of NH{sub 3} relative to the low decomposition temperature of InN (560-570 C). However, there is significant interest in developing an MOCVD process for InN and InGaN growth since MOCVD technology is the technology currently in use for commercial fabrication of group III nitride thin films. This thesis is therefore focused on a study of MOCVD growth of n- and p-type InN and In-rich InGaN films with the goal of providing new information on the influence of growth conditions on the film properties. Initially, a detailed investigation of MOCVD of InN is given. It is shown that MOCVD growth parameters (growth temperature and V/III ratio) have impacts on the layer properties such as In droplet formation on the surface as well as on its electrical and optical properties. PAS is employed for point defect analyzation. It is shown that In vacancies isolated by nitrogen vacancies are the dominant vacancy-type positron traps in InN. A decrease in the N vacancy concentration in InN is observed as a result of the growth temperature increase from 500 to 550 C. This is an indication of a reduction of N vacancy concentration by enhancing NH{sub 3} dissociation at high growth temperature. Results obtained from optical techniques (Raman and PL) are used to estimate the free carrier concentrations in InN. Electrical characterizations are also carried out using Hall measurements. Carrier concentration values obtained by these three techniques

    We analyzed the atomic structure around Mg atoms in MOCVD- and MBE-grown Mg-doped InN using Mg K-edge X-ray absorption fine-structure (XAFS) measurements. Our experimental data closely fit to the simulated data in which Mg atoms occupy the substitutional sites of In atoms. From this result, we conclude that Mg atoms essentially occupy not N atoms sites but In atoms sites, meaning that Mg atoms can act as acceptors in InN. We believe that observations of p-type conductivity are prevented by problems such as carrier compensation and electron accumulation at the surface. (copyright 2008 WILEY-VCH Verlag GmbH and Co.

    To ascertain any predictors of potential food poisoning pathogens and development of post-infective irritable bowel syndrome (IBS) in UK travellers. An analysis was undertaken on prospectively collected data on 527 patients reporting symptoms of suspected food poisoning between June 2012 and June 2015. Positive stool sample indicative of food poisoning pathogens and diagnosis of post-infective IBS. Data on 527 patients were examined. The large majority of patients did not provide a stool sample on return from holiday (n = 430, 81.6%) as few visited a Doctor locally or in the UK. Only 18 patients (18.6%, 95% confidence interval [CI] 11.4-27.7) who provided a stool sample were positive for microbiological food poisoning pathogens. Univariate analysis indicated a significant relationship between a positive stool sample and whether the individual sought any medical assistance at the resort (odds ratio [OR] 0.24, 95% CI 0.08-0.70) and whether they took any treatment (including self-medicated), (OR 0.21, 95% CI 0.06-0.67). Of the 527 patients only 30 (5.7%, 95% CI 3.9-8.1) experienced post-infective IBS. Univariate regression indicated a significant relationship between experiencing Per Rectal (PR) bleeding and a diagnosis of post-infective IBS (OR 3.64, 95% CI 1.00-10.49). Univariate regression also indicated an increase in the risk of developing post-infective IBS with increasing duration of symptoms (OR 1.04, 95% CI 1.02-1.05). No significant relationship was found between a positive stool sample and developing post-infective IBS (P = 0.307). Very few patients provide a stool sample after experiencing holiday sickness abroad. Of those that do, only a small proportion have a positive stool sample indicative of a food poisoning microorganism. Around 6% of individuals were diagnosed with post-infective IBS. Those individuals with PR bleeding and symptoms persisting for longer durations were significantly more at risk of developing post-infective IBS, whilst

    Full Text Available Background: Poinsettia (Euphorbia pulcherrima, holly (Ilex opaca and mistletoe (Phoradendron flavescens adorn homes during the Christmas and New Year holiday season and create the potential for curious children to sample their colorful leaves and enticing berries. This study was aimed to review the American Association of Poison Control Centers National Poison Data System (AAPCC NPDS to describe the epidemiologic profile of ingestion of these plants and to determine whether there was associated morbidity and mortality. Methods: All plant ingestion exposures reported to American poison centers (PCs from 2000-2009 were analyzed to identify all exposures to E. pulcherrima, I. opaca and P. flavescens. The data analysis included ingestions by age, gender, patient management site, symptoms, intention and outcome. Results: The AAPCC NPDS database included 668,111 plant ingestions during 2000 to 2009. E. pulcherrima (19,862; 3.0%, I. opaca (5,432; 0.8% and P. flavescens (1,138; 0.2% exposures accounted for 26,632 (4.0% of all plant ingestion exposures. Children younger than six years were responsible for majority of ingestions (88.0%. Ingestions were more likely to occur unintentionally (P < 0.001. Most cases (96.1% were asymptomatic. When clinical effects developed (1,046 cases, the most frequent reported signs were gastrointestinal in nature (59.8% including abdominal pain, diarrhea and/or vomiting. Moreover, the development of gastrointestinal signs was higher in patients who ingested P. flavescens compared to the other two species. Most exposures (96.1% were managed at home with the guidance from PC experts. When the outcome was known, the majority of exposures (89.2% experienced no adverse effects. Moderate effects occurred in only 28 ingestions (0.1%, and one major effect was recorded in a patient who ingested poinsettia. Conclusion: These holiday plants were associated with extremely low morbidity and no mortality. Home management along with

    High crystalline layers of InN were grown on MgO(100) substrates by gas source molecular beam epitaxy. Good quality films were obtained by means of an in-plane rotation process induced by the annealing of an InN buffer layer to minimize the misfit between InN and MgO. In situ reflection high-energy electron diffraction showed linear streaky patterns along the [011{sup ¯}0] azimuth and a superimposed diffraction along the [112{sup ¯}0] azimuth, which correspond to a 30° α-InN film rotation. This rotation reduces the mismatch at the MgO/InN interface from 19.5% to less than 3.5%, increasing the structural quality, which was analyzed by high-resolution X-ray diffraction and Raman spectroscopy. Only the (0002) c plane diffraction of α-InN was observed and was centered at 2θ = 31.4°. Raman spectroscopy showed two modes corresponding to the hexagonal phase: E1(LO) at 591 cm{sup −1} and E2(high) at 488 cm{sup −1}. Hall effect measurements showed a carrier density of 9 × 10{sup 18} cm{sup −3} and an electron Hall mobility of 340 cm{sup 2}/(V s) for a film thickness of 140 nm.

    2009-05-01

    To improve crystal quality of InN, an in-situ cyclic rapid pulse annealing during growth was carried out using infrared-lamp-heated molecular beam epitaxy. A cycle of 4 min growth of InN at 400 °C and 3 s pulse annealing at a higher temperature was repeated 15 times on AlN on Si substrate. Annealing temperatures were 550, 590, 620, and 660 °C. The back of Si was directly heated by lamp irradiation through a quartz rod. A total InN film thickness was about 200 nm. With increasing annealing temperature up to 620 °C, crystal grain size by scanning electron microscope showed a tendency to increase, while widths of X-ray diffraction rocking curve of (0 0 0 2) reflection and E 2 (high) mode peak of Raman scattering spectra decreased. A peak of In (1 0 1) appeared in X-ray diffraction by annealing higher than 590 °C, and In droplets were found on the surface by annealing at 660 °C.

    2002-01-01

    We observed strong band edge luminescence at 8.5-200 K from 200-880 nm thick InN films grown on 10 nm thick InN buffer layers on Si(001) and Si(111) substrates by electron cyclotron resonance-assisted molecular beam epitaxy. The InN film on the Si(001) substrate exhibited strong band edge photoluminescence (PL) emission at 1.814 eV at 8.5 K, tentatively assigned as donor to acceptor pair [DAP (α-InN)] emission from wurtzite-InN (α-InN) crystal grains, while those on Si(111) showed other stronger band edge PL emissions at 1.880, 2.081 and 2.156 eV, tentatively assigned as donor bound exciton [D 0 X(α-InN)] from α-InN grains, DAP (β-InN) and D 0 X (β-InN) emissions from zinc blende-InN (β-InN) grains, respectively

    In the literature, there are controversies on the interpretation of the appearance in InN Raman spectra of a strong scattering peak in the energy region of the unscreened longitudinal optical (LO) phonons, although a shift caused by the phonon-plasmon interaction is expected for the high conductance observed in this material. Most measurements on light scattering are performed on ensembles of InN nanowires (NWs). However, it is important to investigate the behavior of individual nanowires and here we report on micro-Raman measurements on single nanowires. When changing the polarization direction of the incident light from parallel to perpendicular to the wire, the expected reduction of the Raman scattering was observed for transversal optical (TO) and E 2 phonon scattering modes, while a strong symmetry-forbidden LO mode was observed independently on the laser polarization direction. Single Mg- and Si-doped crystalline InN nanowires were also investigated. Magnesium doping results in a sharpening of the Raman peaks, while silicon doping leads to an asymmetric broadening of the LO peak. The results can be explained based on the influence of the high electron concentration with a strong contribution of the surface accumulation layer and the associated internal electric field.

  20. State Patty’s Day: College Student Drinking and Local Crime Increased on a Student-constructed Holiday

    Lefkowitz, Eva S.; Patrick, Megan E.; Morgan, Nicole R.; Bezemer, Denille H.; Vasilenko, Sara A.

    2012-01-01

    College student alcohol consumption is a major concern, and is known to increase during the celebration of special events. This study examined a student-constructed holiday, State Patty’s Day, at a university with a dominant drinking culture using three sources of data – coded data from Facebook groups, daily web surveys from first-year students (N= 227, 51% male, age 18 to 20; 27.3% Hispanic/Latino; of non-Hispanic/Latino, 26.9% of sample European American/White, 19.4% Asian American/Hawaiian/Pacific Islander, 15.9% African American/Black, 10.6% more than one race), and criminal offense data from police records. Results indicated that messages about State Patty’s Day on Facebook focused on drinking and social aspects of the holiday, such as the social context of drinking, a sense of belonging to a larger community, and the social norms of drinking. These messages were rarely about consequences and rarely negative. On State Patty’s Day, 51% of students consumed alcohol, compared to 29% across other sampled weekend days. Students consumed more drinks (M = 8.2 [SD = 5.3] drinks per State Patty’s Day drinker) and were more likely to engage in heavy drinking on State Patty’s Day, after controlling for gender, drinking motives, and weekend, demonstrating the event-specific spike in heavy drinking associated with this holiday. The impact of this student-constructed holiday went beyond individual drinking behavior; alcohol-specific and other crime also peaked on State Patty’s Day and the day after. Event-specific prevention strategies may be particularly important in addressing these spontaneous, quickly-constructed, and dynamic events. PMID:22685369

  1. School Term vs. School Holiday: Associations with Children's Physical Activity, Screen-Time, Diet and Sleep.

    2015-07-30

    This cross-sectional study examined differences in children's health behaviors during school term (ST) versus school holiday (SH: June-July) and how associations changed when weather characteristics were considered. Children aged 5-18 years (n = 406) from a subtropical climate reported behaviors over 20 months. Multivariable regression models controlling for age, sex, race and body mass index z-score (BMIz) were used to examine associations between SH and each behavior. A second model included heat index, precipitation and daylight hours. Strenuous activity, moderate activity, total activity and TV viewing were significantly higher during SH than ST. After adjusting for weather characteristics, total activity remained significantly higher during SH, but the association with TV viewing was attenuated. Youth surveyed during high precipitation were significantly less likely to meet physical activity guidelines. There were no significant associations between SH and meeting sleep, physical activity or screen-time guidelines. Weather characteristics influenced associations between SH and youth's physical activity and TV viewing.

    Full Text Available Abstract Background People travelling abroad tend to increase their use of alcohol and other drugs. In the present study we describe organized party activities in connection with young tourists' drinking, and the differences between young people travelling with and without organized party activities. Methods We conducted ethnographic observations and a cross-sectional survey in Sunny Beach, Bulgaria. Results The behaviour of the guides from two travel agencies strongly promoted heavy drinking, but discouraged illicit drug use. Even after controlling for several potential confounders, young people who travelled with such "party package travel agencies" were more likely to drink 12 or more units when going out. In univariate analyses, they were also more likely to get into fights, but were not more likely to seek medical assistance or medical assistance for an accident or an alcohol-related problem. After controlling for confounders, the association between type of travel agency and getting into fights was no longer significant. Short-term consequences of drinking in the holiday resort did not differ between party package travellers and ordinary package travellers. Conclusion There may be a small impact of party package travels on young people's drinking. Strategies could be developed used to minimise the harm associated with both party package travel and other kinds of travel where heavy substance use is likely to occur.

  4. Assessing population movement impacts on urban heat island of Beijing during the Chinese New Year holiday: effects of meteorological conditions

    Wu, Lingyun; Zhang, Jingyong

    2018-02-01

    Chinese New Year (CNY), or Spring Festival, is the most important of all festivals in China. We use daily observations to show that Beijing's urban heat island (UHI) effects largely depend on precipitation, cloud cover, and water vapor but are insensitive to wind speed, during the CNY holiday season. Non-precipitating, clear, and low humidity conditions favor strong UHI effects. The CNY holiday, with some 3 billion journeys made, provides a living laboratory to explore the role of population movements in the UHI phenomenon. Averaged over the period 2004-2013, with the Olympic year of 2008 excluded, Beijing's UHI effects during the CNY week decline by 0.48 °C relative to the background period (4 weeks including 2 to 3 weeks before, and 2 to 3 weeks after, the CNY week). With combined effects of precipitation, large cloud cover, and high water vapor excluded, the UHI effects during the CNY week averaged over the study period decline by 0.76 °C relative to the background period, significant at the 99% confidence level by Student's t test. These results indicate that the impacts of population movements can be more easily detected when excluding unfavorable meteorological conditions to the UHI. Population movements occur not only during the CNY holiday, but also during all the time across the globe. We suggest that better understanding the role of population movements will offer new insight into anthropogenic climate modifications.

    The reduction of traffic flow in downtown areas during the Chinese National Day holiday and the fireworks during the Spring Festival provide a unique opportunity for investigating the impact of urban anthropogenic activities on aerosol optical properties during these important Chinese festivals in Beijing. The National Day in 2014 and 2015 and Spring Festival in 2015 and 2016 were selected as study periods. The aerosol optical depth (AOD) at 440 nm increased over the all holiday periods and the average AODs during the 2015 National Day, 2015 Spring Festival and 2016 Spring Festival were about 81%, 21% and 36% higher than the background levels, respectively. The average AOD in 2014 National Day holiday was lower than background level partly influenced by precipitation event. The absorption AOD (AAOD) at 440 nm showed consistent variations with the AOD and the average AAODs during the 2015 National Day, 2015 Spring Festival and 2016 Spring Festival holidays were about 75%, 19% and 23% higher than the background level, respectively. The mean values of single scattering albedo were greater than the background level during the Spring Festival holidays, whereas the values during the National Day holiday in 2015 were lower partly due to the reduction of vehicular emissions in downtown areas. Fine- and coarse-mode particle volumes during pollution periods in holidays were 0.04-0.25 μm3 and 0.03-0.15 μm3 larger than background level, respectively. The results of potential source contribution function and concentration-weighted trajectory analyses identified the areas south of Beijing as the main source regions of PM2.5 and were responsible for the extremely high PM2.5 concentrations in Beijing during the holiday periods. The findings of this study may aid understanding the effects of human activities on aerosol optical properties over Beijing area and contribute to improving regional air quality.

    For large areas without highly detailed data the empirical Universal Soil Loss Equation (USLE) is widely used to quantify soil loss. The problem though is usually the quantification of actual sediment influx into the rivers. As the USLE provides long-term mean soil loss rates, it is often combined with spatially lumped models to estimate the sediment delivery ratio (SDR). But it gets difficult with spatially lumped approaches in large catchment areas where the geographical properties have a wide variance. In this study we developed a simple but spatially distributed approach to quantify the sediment delivery ratio by considering the characteristics of the flow paths in the catchments. The sediment delivery ratio was determined using an empirical approach considering the slope, morphology and land use properties along the flow path as an estimation of travel time of the eroded particles. The model was tested against suspended solids measurements in selected sub-basins of the River Inn catchment area in Germany and Austria, ranging from the high alpine south to the Molasse basin in the northern part.

    The temporal evolution of high quality indium nitride (InN) growth by plasma-assisted atomic layer epitaxy (ALEp) on a-plane sapphire at 200 and 248 °C was probed by synchrotron x-ray methods. The growth was carried out in a thin film growth facility installed at beamline X21 of the National Synchrotron Light Source at Brookhaven National Laboratory and at beamline G3 of the Cornell High Energy Synchrotron Source, Cornell University. Measurements of grazing incidence small angle x-ray scattering (GISAXS) during the initial cycles of growth revealed a broadening and scattering near the diffuse specular rod and the development of scattering intensities due to half unit cell thick nucleation islands in the Yoneda wing with correlation length scale of 7.1 and 8.2 nm, at growth temperatures (Tg) of 200 and 248 °C, respectively. At about 1.1 nm (two unit cells) of growth thickness nucleation islands coarsen, grow, and the intensity of correlated scattering peak increased at the correlation length scale of 8.0 and 8.7 nm for Tg = 200 and 248 °C, respectively. The correlated peaks at both growth temperatures can be fitted with a single peak Lorentzian function, which support single mode growth. Post-growth in situ x-ray reflectivity measurements indicate a growth rate of ~0.36 Å/cycle consistent with the growth rate previously reported for self-limited InN growth in a commercial ALEp reactor. Consistent with the in situ GISAXS study, ex situ atomic force microscopy power spectral density measurements also indicate single mode growth. Electrical characterization of the resulting film revealed an electron mobility of 50 cm2/V s for a 5.6 nm thick InN film on a-plane sapphire, which is higher than the previously reported mobility of much thicker InN films grown at higher temperature by molecular beam epitaxy directly on sapphire. These early results indicated that in situ synchrotron x-ray study of the epitaxial growth kinetics of InN films is a very powerful method to

    Previous studies (mostly questionnaire-based in children) suggest that outdoor activity is protective against myopia. There are few studies on young adults investigating both the impact of simply being outdoors versus performing physical activity. The aim was to study the relationship between the refractive error of young adults and their physical activity patterns. Twenty-seven university students, aged 18 to 25 years, wore a pedometer (Omron HJ720ITE) for seven days both during the semester and holiday periods. They simultaneously recorded the type of activity performed, its duration, the number of steps taken (from the pedometer) and their location (indoors/outdoors) in a logbook. Mean spherical refractive error was used to divide participants into three groups (emmetropes: +1.00 to -0.50 D, low myopes: -0.62 to -3.00 D, higher myopes: -3.12 D or greater myopia). There were no significant differences between the refractive groups during the semester or holiday periods; the average daily times spent outdoors, the duration of physical activity, the ratio of physical activity performed outdoors to indoors and amount of near work performed were similar. The peak exercise intensity was similar across all groups: approximately 100 steps per minute, a brisk walk. Up to one-third of all physical activity was performed outdoors. There were some significant differences in activities performed during semester and holiday times. For example, low myopes spent significantly less time outside (49 ± 47 versus 74 ± 41 minutes, p = 0.005) and performed less physical activity (6,388 ± 1,747 versus 6,779 ± 2,746 steps per day; p = 0.03) during the holidays compared to during semester. The fact that all groups had similar low exercise intensity but many were not myopic suggests that physical activity levels are not critical. There were differences in the activity patterns of low myopes during semester and holiday periods. This study highlights the need for a larger longitudinal

    To describe a project carried out in order to improve the process of Continuous Health Care (CHC) on Saturdays and bank holidays in Primary Care, area number 4, Madrid. The aim of this project was to guarantee a safe and error-free service to patients receiving home health care on weekends. The urgent need for improving CHC process was identified by the Risk Management Functional Unit (RMFU) of the area. In addition, some complaints had been received from the nurses involved in the process as well as from their patients. A SWOT (Strengths, Weaknesses, Opportunities and Threats) analysis performed in 2009 highlighted a number of problems with the process. As a result, a project for improvement was drawn up, to be implemented in the following stages: 1. Redesigning and improving the existing process. 2. Application of failure mode and effect analysis (FMEA) to the new process. 3. Follow up, managing and leading the project. 4. Nurse training. 5. Implementing the process in the whole area. 6. CHC nurse satisfaction surveys. After carrying out this project, the efficiency and level of automation improved considerably. Since implementation of the process enhancement measures, no complaints have been received from patients and surveys show that CHC nurse satisfaction has improved. By using FMEA, errors were given priority and enhancement steps were taken in order to: Inform professionals, back-up personnel and patients about the process. Improve the specialist follow-up report. Provide training in ulcer patient care. The process enhancement, and especially its automation, has resulted in a significant step forward toward achieving greater patient safety. FMEA was a useful tool, which helped in taking some important actions. Finally, CHC nurse satisfaction has clearly improved. Copyright © 2009 SECA. Published by Elsevier Espana. All rights reserved.

  11. Aerosol composition and sources during the Chinese Spring Festival: fireworks, secondary aerosol, and holiday effects

    2015-06-01

    Aerosol particles were characterized by an Aerodyne aerosol chemical speciation monitor along with various collocated instruments in Beijing, China, to investigate the role of fireworks (FW) and secondary aerosol in particulate pollution during the Chinese Spring Festival of 2013. Three FW events, exerting significant and short-term impacts on fine particles (PM2.5), were observed on the days of Lunar New Year, Lunar Fifth Day, and Lantern Festival. The FW were shown to have a large impact on non-refractory potassium, chloride, sulfate, and organics in submicron aerosol (PM1), of which FW organics appeared to be emitted mainly in secondary, with its mass spectrum resembling that of secondary organic aerosol (SOA). Pollution events (PEs) and clean periods (CPs) alternated routinely throughout the study. Secondary particulate matter (SPM = SOA + sulfate + nitrate + ammonium) dominated the total PM1 mass on average, accounting for 63-82% during nine PEs in this study. The elevated contributions of secondary species during PEs resulted in a higher mass extinction efficiency of PM1 (6.4 m2 g-1) than during CPs (4.4 m2 g-1). The Chinese Spring Festival also provides a unique opportunity to study the impact of reduced anthropogenic emissions on aerosol chemistry in the city. Primary species showed ubiquitous reductions during the holiday period with the largest reduction being in cooking organic aerosol (OA; 69%), in nitrogen monoxide (54%), and in coal combustion OA (28%). Secondary sulfate, however, remained only slightly changed, and the SOA and the total PM2.5 even slightly increased. Our results have significant implications for controlling local primary source emissions during PEs, e.g., cooking and traffic activities. Controlling these factors might have a limited effect on improving air quality in the megacity of Beijing, due to the dominance of SPM from regional transport in aerosol particle composition.

  12. West and East

    2017-12-01

    Full Text Available The topic “West-East” has a clear cultural and historical meaning. Orthodox temples face East. The way from West to East and from East to West is tens of thousands of kilometers long and has a special meaning. It differs from the way from North to South: the horizontal axes connect regions, while the vertical axis (Earth-Sky connects the worlds. The expansion of Eurasian tribes occurred along the East-West axis – the world horizontal way. Today the cultural memory of people in the East and West finds itself in the theatre of new dramas of existence and new forces. With the advances in electronic technologies, the world movements seem to have sunk in the depth of the chthonian past to come up anew to the surface of fantastic speeds and momentary connections. A new type of planetary landscape-space relation appears, giving no place for West and East.

  13. Influences of residual oxygen impurities, cubic indium oxide grains and indium oxy-nitride alloy grains in hexagonal InN crystalline films grown on Si(111) substrates by electron cyclotron resonance plasma-assisted molecular beam epitaxy

    Yodo, T.; Nakamura, T.; Kouyama, T.; Harada, Y.

    2005-01-01

    We investigated the influences of residual oxygen (O) impurities, cubic indium oxide (β-In 2 O 3 ) grains and indium oxy-nitride (InON) alloy grains in 200 nm-thick hexagonal (α)-InN crystalline films grown on Si(111) substrates by electron cyclotron resonance plasma-assisted molecular beam epitaxy. Although β-In 2 O 3 grains with wide band-gap energy were formed in In film by N 2 annealing, they were not easily formed in N 2 -annealed InN films. Even if they were not detected in N 2 -annealed InN films, the as-grown films still contained residual O impurities with concentrations of less than 0.5% ([O]≤0.5%). Although [O]∝1% could be estimated by investigating In 2 O 3 grains formed in N 2 -annealed InN films, [O]≤0.5% could not be measured by it. However, we found that they can be qualitatively measured by investigating In 2 O 3 grains formed by H 2 annealing with higher reactivity with InN and O 2 , using X-ray diffraction and PL spectroscopy. In this paper, we discuss the formation mechanism of InON alloy grains in InN films. (copyright 2005 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim) (orig.)

  14. A new perspective on soil erosion: exploring a thermodynamic approach in a small area of the River Inn catchment

    Reid, Lucas; Scherer, Ulrike; Zehe, Erwin

    2016-04-01

    Soil erosion modeling has always struggled with compensating for the difference in time and spatial scale between model, data and the actual processes involved. This is especially the case with non-event based long-term models based on the Universal Soil Loss Equation (USLE), yet USLE based soil erosion models are among the most common and widely used for they have rather low data requirements and can be applied to large areas. But the majority of mass from soil erosion is eroded within short periods of times during heavy rain events, often within minutes or hours. Advancements of the USLE (eg. the Modified Universal Soil Loss Equation, MUSLE) allow for a daily time step, but still apply the same empirical methods derived from the USLE. And to improve the actual quantification of sediment input into rivers soil erosion models are often combined with a Sediment Delivery Ratio (SDR) to get results within the range of measurements. This is still a viable approach for many applications, yet it leaves much to be desired in terms of understanding and reproducing the processes behind soil erosion and sediment input into rivers. That's why, instead of refining and retuning the existing methods, we explore a more comprehensive, physically consistent description on soil erosion. The idea is to describe soil erosion as a dissipative process (Kleidon et al., 2013) and test it in a small sub-basin of the River Inn catchment area in the pre-Alpine foothills. We then compare the results to sediment load measurements from the sub-basin and discuss the advantages and issues with the application of such an approach.

  15. Influence of defects on the absorption edge of InN thin films: The band gap value

    Thakur, J. S.; Danylyuk, Y. V.; Haddad, D.; Naik, V. M.; Naik, R.; Auner, G. W.

    2007-07-01

    We investigate the optical-absorption spectra of InN thin films whose electron density varies from ˜1017tõ1021cm-3 . The low-density films are grown by molecular-beam-epitaxy deposition while highly degenerate films are grown by plasma-source molecular-beam epitaxy. The optical-absorption edge is found to increase from 0.61to1.90eV as the carrier density of the films is increased from low to high density. Since films are polycrystalline and contain various types of defects, we discuss the band gap values by studying the influence of electron degeneracy, electron-electron, electron-ionized impurities, and electron-LO-phonon interaction self-energies on the spectral absorption coefficients of these films. The quasiparticle self-energies of the valence and conduction bands are calculated using dielectric screening within the random-phase approximation. Using one-particle Green’s function analysis, we self-consistently determine the chemical potential for films by coupling equations for the chemical potential and the single-particle scattering rate calculated within the effective-mass approximation for the electron scatterings from ionized impurities and LO phonons. By subtracting the influence of self-energies and chemical potential from the optical-absorption edge energy, we estimate the intrinsic band gap values for the films. We also determine the variations in the calculated band gap values due to the variations in the electron effective mass and static dielectric constant. For the lowest-density film, the estimated band gap energy is ˜0.59eV , while for the highest-density film, it varies from ˜0.60tõ0.68eV depending on the values of electron effective mass and dielectric constant.

  17. The impact of mass gatherings and holiday traveling on the course of an influenza pandemic: a computational model.

    Shi, Pengyi; Keskinocak, Pinar; Swann, Julie L; Lee, Bruce Y

    2010-12-21

    During the 2009 H1N1 influenza pandemic, concerns arose about the potential negative effects of mass public gatherings and travel on the course of the pandemic. Better understanding the potential effects of temporal changes in social mixing patterns could help public officials determine if and when to cancel large public gatherings or enforce regional travel restrictions, advisories, or surveillance during an epidemic. We develop a computer simulation model using detailed data from the state of Georgia to explore how various changes in social mixing and contact patterns, representing mass gatherings and holiday traveling, may affect the course of an influenza pandemic. Various scenarios with different combinations of the length of the mass gatherings or traveling period (range: 0.5 to 5 days), the proportion of the population attending the mass gathering events or on travel (range: 1% to 50%), and the initial reproduction numbers R0 (1.3, 1.5, 1.8) are explored. Mass gatherings that occur within 10 days before the epidemic peak can result in as high as a 10% relative increase in the peak prevalence and the total attack rate, and may have even worse impacts on local communities and travelers' families. Holiday traveling can lead to a second epidemic peak under certain scenarios. Conversely, mass traveling or gatherings may have little effect when occurring much earlier or later than the epidemic peak, e.g., more than 40 days earlier or 20 days later than the peak when the initial R0 = 1.5. Our results suggest that monitoring, postponing, or cancelling large public gatherings may be warranted close to the epidemic peak but not earlier or later during the epidemic. Influenza activity should also be closely monitored for a potential second peak if holiday traveling occurs when prevalence is high.

  18. High energy ion irradiated III-N semiconductors (AlN, GaN, InN): study of point defect and extended defect creation

    Sall, Mamour

    2013-01-01

    Nitride semiconductors III N (AlN, GaN, InN) have interesting properties for micro-and opto-electronic applications. In use, they may be subjected to different types of radiation in a wide range of energy. In AlN, initially considered insensitive to electronic excitations (Se), we have demonstrated a novel type of synergy between Se and nuclear collisions (Sn) for the creation of defects absorbing at 4.7 eV. In addition, another effect of Se is highlighted in AlN: climb of screw dislocations under the influence of Se, at high fluence. In GaN, two mechanisms can explain the creation of defects absorbing at 2.8 eV: a synergy between Se and Sn, or a creation only due to Sn but with a strong effect of the size of displacement cascades. The study, by TEM, of the effects of Se in the three materials, exhibits behaviors highly dependent on the material while they all belong to the same family with the same atomic structure. Under monoatomic ion irradiations (velocity between 0.4 and 5 MeV/u), while discontinuous tracks are observed in GaN and InN, no track is observed in AlN with the highest electronic stopping power (33 keV/nm). Only fullerene clusters produce tracks in AlN. The inelastic thermal spike model was used to calculate the energies required to produce track in AlN, GaN and InN, they are 4.2 eV/atom, 1.5 eV/atom and 0.8 eV/atom, respectively. This sensitivity difference according to Se, also occurs at high fluence. (author)

    2017-05-31

    Acute bacterial pneumonia is a common and potentially fatal disease where early recognition and treatment are crucial. Increasing medical literature suggests worse outcomes in patients admitted for medical and surgical conditions during the weekend. Little is known about this effect in patients with acute bacterial pneumonia. Obective: The aim of this study was to evaluate the impact of weekend and holiday hospital admission on the outcomes of acute bacterial pneumonia. Retrospective analysis of adult patients (> 18 years) with acute bacterial pneumonia collected from a tertiary referral center database. Length of stay, total cost, admission to intensive care unit, development of sepsis and organ failure, and mortality were compared between patients admitted on a weekday and patients admitted during a weekend or holiday. We analyzed 53 854 hospital admissions from 42 512 patients (median age 84.0 years, range 18 - 118 years), corresponding to 30 554 admissions during weekdays, 21 222 at weekends and 2078 during public holidays. Weekend and holiday admission was not associated with increased costs, length of stay, intensive care unit admission, development of sepsis, organ failure, and mortality. A weekend/holiday effect in acute bacterial pneumonia was not evident in our series.

  1. Proposal and achievement of novel structure InN/GaN multiple quantum wells consisting of 1 ML and fractional monolayer InN wells inserted in GaN matrix

    Yoshikawa, A.; Che, S. B.; Yamaguchi, W.; Saito, H.; Wang, X. Q.; Ishitani, Y.; Hwang, E. S.

    2007-01-01

    The authors propose and demonstrate the fabrication of InN/GaN multiple quantum well (MQW) consisting of 1 ML and fractional monolayer InN well insertion in GaN matrix under In-polarity growth regime. Since the critical thickness of InN epitaxy on GaN is about 1 ML and the growth temperature for 1 ML InN insertion can be remarkably higher, the proposed MQW structure can avoid/reduce generation of misfit dislocation, resulting in higher quality MQW-structure nature in principle than former InN-based MQWs. The proposed InN/GaN MQWs are potentially applicable to room temperature operating excitonic devices working in short-wavelength visible colors

  2. The chemical composition and sources of PM2.5 during the 2009 Chinese New Year's holiday in Shanghai

    2012-11-01

    China is virtually shut down during the week-long Chinese New Year's holiday. This implies that the anthropogenic emissions would be greatly decreased during the period thus providing an opportunity to study the air quality in China under reduced emissions, and the drastic emission changes during a short period of time allows the comparison of source contributions under significantly different conditions. Seventeen PM2.5 samples were collected during the 2009 Chinese New Year's holiday in Shanghai to study the composition and sources of the fine particles. Organic carbon (OC), elemental carbon (EC), eight water-soluble ions, fourteen metals and solvent extractable organic compounds (SEOC) including alkanes, hopanes, polycyclic aromatic hydrocarbons (PAHs) and fatty acids were measured. Diagnostic PAH ratios, correlation analysis of OC, EC, n-alkanes, hopanes and PAHs showed that vehicle emissions were the main source of n-alkanes and EC, and an important source of the locally emitted particulate PAHs in urban Shanghai, while coal burning should be the main source of the transported PAHs from the inland areas. The composition of n-fatty acids also provided some clue on the significance of the contribution by kitchen activities. In the New Year's Eve's sample, 75% of the particle mass was estimated to be from fireworks, and K+, SO42 -, Cl-, OC, Al and Ba were the main components. Firework fine particles had high OC/EC ratio and low NO3-/SO42 - ratio.

    Identifying critical periods of greater weight gain could provide useful information to combat the obesity epidemic. We tested whether body weight (BW), body fat percentage (BF%) and blood pressure (BP) changed during the holiday season (thanksgiving to new year's day) and the impact of regular exercise on these parameters. A total of 48 males and 100 females (age 18-65 years) with a mean body mass index of 25.1±0.5 kg/m(2) were evaluated in mid-November (visit 1) and early January (visit 2; across 57±0.5 days). Anthropometric data, BF%, BP and self-reported exercise were recorded. Participants showed significant increases in BW (0.78±0.1 kg, Pholiday weight gain and was not a significant predictor for changes in BW or BF%. Data are reported as means±s.e. Our participants gained an average of 0.78 kg, which indicates the majority of average annual weight gain (1 kg/y) reported by others may occur during the holiday season. Obese participants are most at risk as they showed the greatest increases in BF%. Initial BW, not exercise, significantly predicted BF% and BW gain.

    2016-01-01

    It has been reported that an exaggerated systolic blood pressure (ESBP) response during exercise, even if resting blood pressure is normal, is associated with an increased risk of future hypertension and cardiovascular disease (CVD). This study was designed to investigate the relationships of work duration, sleep duration and number of holidays with blood pressure response during an exercise stress test among normotensive workers. The subjects were 362 normotensive workers (79 males and 283 females; age, 49.1 years). A multi-stage graded submaximal exercise stress test was performed on each subject using an electric bicycle ergometer. The workload was increased every 3 minutes, and blood pressure was measured at rest and during the last 1 minute of each stage. In this study, an ESBP response during exercise was defined according to the criteria of the Framingham Study (peak systolic blood pressure ≥210 mmHg in males, or ≥190 mmHg in females). Working environments, work duration, sleep duration, number of holidays, and physical activity during commuting and work, and leisure time exercise duration were evaluated using a questionnaire. An ESBP response during exercise was observed in 94 (26.0%) workers. The adjusted odds ratio for the prevalence of an ESBP response during exercise was found to be significantly higher with an increase in work duration, decreases in sleep duration and number of holidays (pwork duration with lowest sleep duration and number of holidays groups had significantly higher adjusted odds ratio for the prevalence of an ESBP response during exercise than the lowest work duration with highest sleep duration and number of holidays groups (pwork duration, short sleep duration and small number of holidays.

  6. Profiles of illicit drug use during annual key holiday and control periods in Australia: wastewater analysis in an urban, a semi-rural and a vacation area.

    To examine changes in illicit drug consumption between peak holiday season (23 December-3 January) in Australia and a control period two months later in a coastal urban area, an inland semi-rural area and an island populated predominantly by vacationers during holidays. Analysis of representative daily composite wastewater samples collected from the inlet of the major wastewater treatment plant in each area. Three wastewater treatment plants. Wastewater treatment plants serviced approximately 350, 000 persons in the urban area, 120,000 in the semi-rural area and 1100-2400 on the island. Drug residues were analysed using liquid chromatography coupled to a tandem mass spectrometer. Per capita drug consumption was estimated. Changes in drug use were quantified using Hedges' g. During the holidays, cannabis consumption in the semi-rural area declined (g = -2.8) as did methamphetamine (-0.8), whereas cocaine (+1.5) and ecstasy (+1.6) use increased. In the urban area, consumption of all drugs increased during holidays (cannabis +1.6, cocaine +1.2, ecstasy +0.8 and methamphetamine +0.3). In the vacation area, methamphetamine (+0.7), ecstasy (+0.7) and cocaine (+1.1) use increased, but cannabis (-0.5) use decreased during holiday periods. While the peak holiday season in Australia is perceived as a period of increased drug use, this is not uniform across all drugs and areas. Substantial declines in drug use in the semi-rural area contrasted with substantial increases in urban and vacation areas. Per capita drug consumption in the vacation area was equivalent to that in the urban area, implying that these locations merit particular attention for drug use monitoring and harm minimisation measures. © 2012 The Authors, Addiction © 2012 Society for the Study of Addiction.

  7. Valence-band discontinuities of wurtzite GaN, AlN, and InN heterojunctions measured by x-ray photoemission spectroscopy

    1996-01-01

    The valence-band discontinuities at various wurtzite GaN, AlN, and InN heterojunctions were measured by means of x-ray photoemission spectroscopy. A significant forward endash backward asymmetry was observed in the InN/GaN endash GaN/InN and InN/AlN endash AlN/InN heterojunctions. The asymmetry was understood as a piezoelectric strain effect. We report the valence band discontinuities for InN/GaN=1.05±0.25 eV, GaN/AlN=0.70±0.24 eV, and InN/AlN=1.81±0.20 eV, all in the standard type I lineup. These values obey transitivity to within the experimental accuracy.

    A significant proportion of the average annual body weight (BW) gain in US adults (~0.5-1 kg/y) may result from modest episodes of positive energy balance during the winter holiday season. We tested whether holiday BW gain was reduced in participants with high baseline total energy expenditure (TEE) or whether it varied by BMI (in kg/m(2)). In a secondary analysis of previously published data, ΔBW normalized over 90 d from mid-September/mid-October 1999 to mid-January/early March 2000 was analyzed by sex, age, and BMI in 443 men and women (40-69 y of age). TEE was measured by doubly labeled water. High or low energy expenditure was assessed as residual TEE after linear adjustment for age, height, and BW. No correlations between ΔBW and TEE or TEE residuals were found. Sixty-five percent of men and 58% of women gained ≥0.5 kg BW, with ~50% of both groups gaining ≥1% of preholiday BW. Obese men (BMI ≥30) gained more BW than did obese women. A high preholiday absolute TEE or residual TEE did not protect against BW gain during the winter holiday quarter. It is not known whether higher than these typical TEE levels would protect against weight gain or if the observed gain may be attributed to increased food consumption and/or reduced physical activity during the holiday quarter.

  11. Holidays for Children and Families in Need: An Exploration of the Research and Policy Context for Social Tourism in the UK

    Hazel, Neal

    2005-01-01

    Although provision of holidays for families in need has been mainstreamed within the social care policies of many countries in the rest of Europe, "social tourism" has yet to be adopted in the United Kingdom. This article reports on a scoping study of research and policy in this area. While there is limited robust research on the impact…

  12. Party package travels impact on alcohol use and related problems in a holiday resort - a mixed methods study

    Hesse, Morten; Tutenges, Sébastien; Schliewe, Sanna

    2008-01-01

    Background People travelling abroad tend to increase their use of alcohol and other drugs. In the present study we describe organized party activities in connection with young tourists' drinking, and the differences between young people travelling with and without organized party activities...... travelled with such "party package travel agencies" were more likely to drink 12 or more units when going out. In univariate analyses, they were also more likely to get into fights, but were not more likely to seek medical assistance or medical assistance for an accident or an alcohol-related problem. After...... controlling for confounders, the association between type of travel agency and getting into fights was no longer significant. Short-term consequences of drinking in the holiday resort did not differ between party package travellers and ordinary package travellers. Conclusions There may be a small impact...

  13. Islam and the West

    Mohd. Kamal Hassan

    1997-06-01

    Full Text Available The scientific and technological developments during the 18th and' the 19th centuries ensured material progress of the West, as well as emergence of the West as the dominating power which colonized the rest of the world. During the post-colonial phase, Islam emerged as a revitalized sociopolitical force. This has been mistaken as a threat by the West, and Islam has been portrayed as the "new enemy after the demise of communism. This is partly an effort to establish a Western identity, which is disintegrating due to lack of a challenge; and partly a reflection of the failure of Muslims to realize the social and ethical ideals of Islam.

  14. BONE TURNOVER IN OSTEOPOROTIC WOMEN DURING LONG-TERM ORAL BISPHOSPHONATES TREATMENT: IMPLICATIONS FOR TREATMENT FAILURE AND "DRUG HOLIDAY" IN THE REAL WORLD.

    Liel, Yair; Plakht, Ygal; Tailakh, Muhammad Abu

    2017-07-01

    Little data exist to support concerns over bone turnover suppression during prolonged oral bisphosphonate treatment and on consequences of the recommended "drug holiday." This study was performed to assess bone resorption rates in postmenopausal osteoporotic women on prolonged oral bisphosphonate treatment and in response to switching to "drug holiday" intravenous bisphosphonate, or continuation of oral bisphosphonates. The frequency distribution of the bone resorption marker urinary deoxypyridinoline crosslinks (uDPD), was obtained retrospectively from 211 osteoporotic women attended at an academic hospital endocrine clinic, treated for >2 years with oral bisphosphonates. In some patients, uDPD was re-assessed following modification or continuation of treatment. The mean duration of oral bisphosphonates treatment was 7.2 ± 3.1 years. uDPD was within reference range for premenopausal women in 61.6% of the patients, below in 7.6% of the patients, and above upper limit in 30.8%. uDPD decreased significantly following intravenous zoledronic acid, increased significantly during "drug holiday," and slightly decreased in those continued on oral bisphosphonate treatment. In this real-world study, the majority of women on prolonged oral bisphosphonates maintained bone resorption rates within the normal reference range for premenopausal women. The likelihood for inadequate suppression was considerably greater than that of over-suppression. Implementing a "drug holiday" resulted in a marked increase in bone resorption rates. Additional studies should explore the potential role of bone turnover markers in the evaluation of patients on prolonged oral bisphosphonates and during "drug holiday" in different settings and using additional markers. BMD = bone mineral density; IQR = interquartile range; uDPD = urinary deoxypyridinoline crosslinks.

  15. Structural and electronic properties of InN epitaxial layer grown on c-plane sapphire by chemical vapor deposition technique

    Growth of InN epilayers on c-plane sapphire substrate by chemical vapor deposition technique using pure indium metal and ammonia as precursors has been systematically explored. It has been found that [0001] oriented indium nitride epitaxial layers with smooth surface morphology can be grown on c-plane sapphire substrates by optimizing the growth conditions. Bandgap of the film is observed to be Burstein–Moss shifted likely to be due to high background electron concentration. It has been found that the concentration of this unintentional doping decreases with the increase in the growth temperature and the ammonia flux. Epitaxial quality on the other hand deteriorates as the growth temperature increases. Moreover, the morphology of the deposited layer has been found to change from flat top islands to faceted mounds as the flow rate of ammonia increases. This phenomenon is expected to be related to the difference in surface termination character at low and high ammonia flow rates.

  16. Correcting for day of the week and public holiday effects: improving a national daily syndromic surveillance service for detecting public health threats.

    Buckingham-Jeffery, Elizabeth; Morbey, Roger; House, Thomas; Elliot, Alex J; Harcourt, Sally; Smith, Gillian E

    2017-05-19

    As service provision and patient behaviour varies by day, healthcare data used for public health surveillance can exhibit large day of the week effects. These regular effects are further complicated by the impact of public holidays. Real-time syndromic surveillance requires the daily analysis of a range of healthcare data sources, including family doctor consultations (called general practitioners, or GPs, in the UK). Failure to adjust for such reporting biases during analysis of syndromic GP surveillance data could lead to misinterpretations including false alarms or delays in the detection of outbreaks. The simplest smoothing method to remove a day of the week effect from daily time series data is a 7-day moving average. Public Health England developed the working day moving average in an attempt also to remove public holiday effects from daily GP data. However, neither of these methods adequately account for the combination of day of the week and public holiday effects. The extended working day moving average was developed. This is a further data-driven method for adding a smooth trend curve to a time series graph of daily healthcare data, that aims to take both public holiday and day of the week effects into account. It is based on the assumption that the number of people seeking healthcare services is a combination of illness levels/severity and the ability or desire of patients to seek healthcare each day. The extended working day moving average was compared to the seven-day and working day moving averages through application to data from two syndromic indicators from the GP in-hours syndromic surveillance system managed by Public Health England. The extended working day moving average successfully smoothed the syndromic healthcare data by taking into account the combined day of the week and public holiday effects. In comparison, the seven-day and working day moving averages were unable to account for all these effects, which led to misleading smoothing

  5. Effects of the summer holiday season on UV filter and illicit drug concentrations in the Korean wastewater system and aquatic environment.

    Kim, Ki Yong; Ekpeghere, Kalu Ibe; Jeong, Hee-Jin; Oh, Jeong-Eun

    2017-08-01

    Seasonal variations in the concentrations of eight ultraviolet (UV) filters and 22 illicit drugs including their metabolites in the Korean aquatic environment were investigated. Seawater samples from three beaches, water samples from two rivers, and influents and effluents from three wastewater treatment plants were analyzed. The UV filter concentrations in the seawater, river water, and effluent samples were 39.4-296, 35.4-117, and 6.84-51.1 ng L -1 , respectively. The total UV filter concentrations in the seawater samples were 1.9-4.4 times higher at the peak of the holiday season than outside the peak holiday season. An environmental risk assessment showed that ethylhexyl methoxy cinnamate (EHMC) could cause adverse effects on aquatic organisms in the seawater at the three beaches during the holiday period. Seven of the 22 target illicit drugs including their metabolites were detected in the wastewater influent samples, and the total illicit drug concentrations in the influent samples were 0.08-65.4 ng L -1 . The estimated daily consumption rates for cis-tramadol (Cis-TRM), methamphetamine (MTP), meperidine (MEP), and codeine (COD) were 25.7-118.4, 13.8-36.1, 1.36-12.6, and 1.75-8.64 mg d -1 (1000 people) -1 , respectively. In popular vacation area, the illicit drug consumption rates (Cis-TRM, MTP and MEP) were 1.6-2.6 times higher at the peak of the summer holiday season than at the beginning of the summer.

    2013-04-01

    To assess the relationship between ambulance attendances, emergency department (ED) presentations and hospital admissions for acute alcohol intoxication and the timing of public holidays, sporting and social events. Time-series analysis was used to explore trends in intoxication in the context of major events. Population of Melbourne, Victoria, Australia between 2000 and 2009. All patients attended by ambulance, presenting to hospital EDs, or admitted to hospital who were classified as acutely alcohol intoxicated. Analysis of daily numbers of presentations for acute alcohol intoxication associated with major events were undertaken, including lead and lag effects. Analyses controlled for day of week and month of year to address temporal and seasonal variations. Alcohol intoxication presentations were significantly elevated the day before all public holidays, with intoxication cases on the day of public holidays only higher on New Year's Day (ambulance 6.57, 95% confidence intervals (CI): 3.4-9.74; ED 3.34, 95% CI: 1.28-5.4) and ANZAC Day (ambulance 3.71, 95% CI: 0.68-6.75). The Australian Football League (AFL) Grand Final (ED 2.37, 95% CI: 0.55-4.19), Commonwealth Games (ED 2.45, 95% CI: 0.6-4.3) and Melbourne Cup Day (ambulance 6.14, 95% CI: 2.42-9.85) represented the sporting events with significant elevations in acute intoxication requiring medical attention. The last working day before Christmas was the only social event where a significant increase in acute intoxication occurred (ambulance 8.98, 95% CI: 6.8-11.15). Acute alcohol intoxication cases requiring ambulance, emergency department and hospital in-patient treatment increase substantially on the day preceding public holidays and other major social events. © 2012 The Authors, Addiction © 2012 Society for the Study of Addiction.

  7. Toward Cultural Policy Studies on Mobility: Reflections on a Study of the Hong Kong Working Holiday Scheme

    Louis Ho

    2017-05-01

    Full Text Available Cultural policy is predominantly, and practically, considered the sum of a government’s activities with respect to the arts, humanities and heritage. Thus, cultural policy encompasses a much broader range of activities than was traditionally associated with an arts policy. Critical cultural policy studies, then, sees a distinction between ‘explicit’ cultural policies that are manifestly labelled as ‘cultural’, and ‘implicit’ cultural policies that are not labelled as such, but that work to shape cultural experiences. This article considers this explicit/implicit cultural policy distinction through John Urry’s idea of ‘social as mobility’, suggesting that some public policies regarding mobility (such as immigration, international trade and labour policy have led to specific cultural consequences and therefore qualify as implicit cultural policy. Using Hong Kong’s working holiday scheme as a case study, this article explores how an economic policy on temporary immigrant labour involves a deliberate cultural agenda as well as ‘unintentional’ cultural consequences and problematises the fact that cultural policy studies are largely framed by the idea of ‘social as society’.

  8. An Inter-Comparison of the Holiday Climate Index (HCI and the Tourism Climate Index (TCI in Europe

    Daniel Scott

    2016-06-01

    Full Text Available Much research has been devoted to quantifying optimal or unacceptable climate conditions both generally and for specific tourism segments or activities over the last 10 years. This knowledge is not incorporated in the Tourism Climate Index (TCI, which has also been subject to other substantial critiques. To more accurately assess the climatic suitability of destinations for leisure tourism, the Holiday Climate Index (HCI was developed. A major advancement of the HCI is that its variable rating scales and the component weighting system are based on this aforementioned literature of tourists’ stated climatic preferences. This paper will discuss the design of the HCI and how the limitations of the TCI were overcome. It then presents an inter-comparison of the results from HCI:Urban and TCI for geographically diverse urban destinations across Europe. The results illustrate how the HCI:Urban rates the climate of many cities higher than the TCI, particularly in shoulder seasons and the winter months, which is more consistent with observed visitation patterns. The results empirically demonstrate that use of the TCI should be discontinued.

  9. School Term vs. School Holiday: Associations with Children’s Physical Activity, Screen-Time, Diet and Sleep

    Amanda E. Staiano

    2015-07-01

    Full Text Available This cross-sectional study examined differences in children’s health behaviors during school term (ST versus school holiday (SH: June–July and how associations changed when weather characteristics were considered. Children aged 5–18 years (n = 406 from a subtropical climate reported behaviors over 20 months. Multivariable regression models controlling for age, sex, race and body mass index z-score(BMIz ) were used to examine associations between SH and each behavior. A second model included heat index, precipitation and daylight hours. Strenuous activity, moderate activity, total activity and TV viewing were significantly higher during SH than ST. After adjusting for weather characteristics, total activity remained significantly higher during SH, but the association with TV viewing was attenuated. Youth surveyed during high precipitation were significantly less likely to meet physical activity guidelines. There were no significant associations between SH and meeting sleep, physical activity or screen-time guidelines. Weather characteristics influenced associations between SH and youth’s physical activity and TV viewing.

  11. Electrical transport in GaN and InN nanowires; Elektrischer Transport in GaN- und InN-Nanodraehten

    Richter, Thomas Fabian

    2008-12-19

    This thesis discusses the analysis of the electrical transport in GaN and InN nanowires at room temperature and deep temperatures. From those measurements two different transport models for those two in matter of the band banding completely different materials have been found. In the investigation of the GaN nanowires the main focus was the electrical transport in dependence of the diameter and the n-doping. With the use of IV-measurements on those MBE grown nanowires with different diameters at dark and under UV illumination as well as the decay of the persistent photocurrent, it was possible to find an for GaN untypical behaviour. The electrical transport in those wires is extremely diameter dependent. The dark current shows space charged limited current. With the help of those cognitions a diameter dependent transport model could be found. The transport phenomena in those wires is based on the diameter depending band bending at the edge of the wires caused by the Fermi level pinning inside the forbidden band. This model can be fit to the data with the three parameter doping, fermi level pinning and wire diameter. On the base of those effects a method to determine the doping concentration inside those wires without field effect measurements and contact resistance has been developed. The defect structure inside those wires has been analysed with the help of spectral photoluminescence measurements. Here several defect bands have been found and it was possible with help of several contacts on one single wire to determine different defect regions along the wire and to explain them by the lattice mismatch between nanowire and substrate. Further temperature depending measurements and investigations on Schottky contacted wires as well as on GaN wires with AlN tunnel structures complete the work on GaN. The electrical characterisation on a large scale of undoped and doped InN nanowires shows linear growth of the dark current with the diameter up to wires of around 100 nm

  12. The role of nocturnal delivery and delivery during the holiday period in Finland on obstetric anal sphincter rupture rates- a population based observational study

    Vehviläinen-Julkunen Katri

    2010-02-01

    Full Text Available Abstract Background Obstetric anal sphincter rupture (OASR is a serious complication of delivery, which frequently results in faecal incontinence despite primary repair and has serious implications for women's health. The objective of this study was to assess whether human factors, workload and staffing at night, at weekends and during holidays has an effect on the increasing OASR rates among all singleton vaginal deliveries (n = 514,741 having occurred between 1997 and 2007 in Finland. Women (n = 2,849 with OASR were compared in terms of possible risk factors to women without OASR using stepwise logistic regression analysis. Findings In Finland, the increase in OASR rate is striking, from 0.2% in 1997 to 0.9% in 2007. OASR rates varied from 0.49% to 0.58% (≤ 0.001 according to the time of day, and were lowest at night. After adjustment for patient-mix and the use of interventions, the risk of OASR was 11% lower (95% CI 3-18% at night and 15% lower (95% CI 3-26% in July - the main holiday month. Only 14% of the increased OASR risk during the day time (8-23.59 was attributable to vacuum assistance and birth weight, whereas the holiday period had no effect. Conclusions Decreased OASR rates at night and in July suggest that human factors such as decreased alertness due to fatigue or hospitals' administrative factors such as workload and staffing did not increase the rates of OASR.

  13. Temporal Patterns of Alcohol Consumption and Alcohol-Related Road Accidents in Young Swiss Men: Seasonal, Weekday and Public Holiday Effects.

    Foster, Simon; Gmel, Gerhard; Estévez, Natalia; Bähler, Caroline; Mohler-Kuo, Meichun

    2015-09-01

    To assess seasonal, weekday, and public holiday effects on alcohol-related road accidents and drinking diaries among young Swiss men. Federal road accident data (35,485 accidents) from Switzerland and drinking diary data from a large cohort of young Swiss men (11,930 subjects) were analysed for temporal effects by calendar week, weekday and public holiday (Christmas, New Years, National Day). Alcohol-related accidents were analysed using rate ratios for observed versus expected numbers of accidents and proportions of alcohol-related accidents relative to the total number. Drinking diaries were analysed for the proportion of drinkers, median number of drinks consumed, and the 90th percentile's number of drinks consumed. Several parallel peaks were identified in alcohol-related accidents and drinking diaries. These included increases on Fridays and Saturdays, with Saturday drinking extending until early Sunday morning, an increase during the summer on workdays but not weekends, an increase at the end of the year, and increases on public holidays and the evening before. Our results suggest specific time-windows that are associated with increases in drinking and alcohol-related harm. Established prevention measures should be enforced during these time-windows to reduce associated peaks. © The Author 2015. Medical Council on Alcohol and Oxford University Press.

  14. Study of Stark Effect in n-doped 1.55 μm InN0.92yP1-1.92yBiy/InP MQWs

    Bilel, C.; Chakir, K.; Rebey, A.; Alrowaili, Z. A.

    2018-05-01

    The effect of an applied electric field on electronic band structure and optical absorption properties of n-doped InN0.92y P1-1.92y Bi y /InP multiple quantum wells (MQWs) was theoretically studied using a self-consistent calculation combined with the 16-band anti-crossing model. The incorporation of N and Bi atoms into an InP host matrix leads to rapid reduction of the band gap energy covering a large infrared range. The optimization of the well parameters, such as the well/barrier widths, N/Bi compositions and doping density, allowed us to obtain InN0.92y P1-1.92y Bi y /InP MQWs operating at the wavelength 1.55 μm. Application of the electric field causes a red-shift of the fundamental transition energy T 1 accompanied by a significant change in the spatial distribution of confined electron density. The Stark effect on the absorption coefficient of n-doped InN0.92y P1-1.92y Bi y /InP MQWs was investigated. The Bi composition of these MQWs was adjusted for each electric field value in order to maintain the wavelength emission at 1.55 μm.

    Nitride semiconductors (Al,Ga,In)N attain material properties that make them suitable for photovoltaic and optoelectronics devices to be used in hard environments. These properties include an energy gap continuously tuneable within the energy range of the solar spectrum, a high radiation resistance and thermal stability. The developing of efficient devices requires contacts with low resistivity and high transmittance in visible region. ZnO:Al (AZO) emerges as a feasible candidate for transparent contact to nitride semiconductors, taking advantage of its low resistivity, high transparency in visible wavelengths and a very low lattice mismatch with respect to nitride semiconductors. This work presents a study of the applications of AZO films deposited at low-temperature by RF magnetron sputtering as transparent contact for InN layers. The optimization of AZO conditions deposition lead to the obtaining of contacts which shows an ohmic behaviour for the as-deposited layer, regardless the thickness of the ZnO:Al contact layer. Specific contact resistances of 1.6 {omega}.cm{sup 2} were achieved for the contact with 90 nm thick ZnO:Al layer without any post-deposition treatment (copyright 2012 WILEY-VCH Verlag GmbH and Co.

  19. Design and analysis of InN - In0.25Ga0.75N single quantum well laser for short distance communication wavelength

    Polash, Md. Mobarak Hossain; Alam, M. Shah; Biswas, Saumya

    2018-03-01

    A single quantum well semiconductor laser based on wurtzite-nitride is designed and analyzed for short distance communication wavelength (at around 1300 nm). The laser structure has 12 Å well layer of InN, 15 Å barrier layer of In0.25Ga0.75N, and 54 Å separate confinement heterostructure layer of GaN. To calculate the electronic characteristics of the structure, a self-consistent method is used where Hamiltonian with effective mass approximation is solved for conduction band while six-bands Hamiltonian matrix with k · p formalism including the polarization effect, valence-band mixing effect, and strain effect is solved for valence band. The interband optical transition elements, optical gain, differential gain, radiative current density, spontaneous emission rate, and threshold characteristics have been calculated. The wave function overlap integral is found to be 45.93% for TE-polarized structure. Also, the spontaneous emission rate is found to be 6.57 × 1027 s - 1 cm - 3 eV - 1 at 1288.21 nm with the carrier density of 5 × 1019 cm - 3. Furthermore, the radiative current density and the radiative recombination rate are found to be 121.92 A cm - 2 and 6.35 × 1027 s - 1 cm - 3, respectively, while the TE-polarized optical gain of the structure is 3872.1 cm - 1 at 1301.7 nm.

  20. Aware, motivated and striving for a 'safe tan': an exploratory mixed-method study of sun-protection during holidays.

    Rodrigues, Angela M; Sniehotta, Falko F; Birch-Machin, Mark A; Araujo-Soares, Vera

    2017-01-01

    Background: This article presents an exploratory study, aiming to explore the correspondence between knowledge, motivation and sun-protection practices during holidays. Methods: Seventeen participants aged 21-62 years old, recruited from community settings took part in individual face-to-face semi-structured interviews, completed sun sensitivity questions and an objective assessment of sunscreen use. Holidaymakers' knowledge about sun-safe messages, intentions and perceptions of barriers and facilitators for sun-protection were assessed. Qualitative data were analysed using thematic analysis and integrated with quantitative data, using a pragmatic theory-informed approach to synthesise the findings. Results: Participants were well informed about sun-safe messages, highly motivated to protect themselves from solar UV radiation (UVR) and they perceived themselves as well protected. However, they did not seem to use effective protective practices. Sunscreen was the preferred method of sun-protection, but most participants used considerably less than the recommended amount and significantly overestimated the amount of time they could be safely exposed. Seeking shade was the least used method of sun-protection and covering-up strategies were mostly implemented as a partial protection (i.e. hats or sunglasses). The desire to reach an optimal balance between getting a tan and using sun-protection to avoid sunburns was preeminent. Several additional barriers and facilitators for sun-protection were identified. Conclusions: Holidaymakers might have a false sense of security when it comes to sun-exposure. They are aware of the need to protect from solar UVR, but the motive for a safe tan, the overreliance on sunscreen, the overestimation of the safe sun-exposure time for their skin type and the insufficient application of sunscreen leaves holidaymakers motivated to protect their skin at significant risk of overexposure, sunburn and skin cancer.

  1. Geothermal investigations in West Virginia

    1982-11-01

    Deep sedimentary basins and warm-spring systems in West Virginia are potential geothermal resources. A temperature gradient map based on 800 bottom-hole temperatures for West Virginia shows that variations of temperature gradient trend northeasterly, parallel to regional structure. Highest temperature gradient values of about 28/sup 0/C/km occur in east-central West Virginia, and the lowest gradients (18/sup 0/C/km) are found over the Rome Trough. Results from ground-water geochemistry indicate that the warm waters circulate in very shallow aquifers and are subject to seasonal temperature fluctuations. Silica heat-flow data in West Virginia vary from about 0.89 to 1.4 HFU and generally increase towards the west. Bouguer, magnetic, and temperature gradient profiles suggest that an ancient rift transects the state and is the site of several deep sedimentary basins.

  2. Ebola in West Africa.

    Raka, Lul; Guardo, Monica

    2015-03-15

    Ebola viral disease (EVD) is a severe and life-threatening disease. The current Ebola outbreak in West Africa entered its second year and is unprecedented because it is the largest one in history, involved urban centers and affected a large number of health care workers. It quickly escalated from medical into a humanitarian, social, economic, and security crisis. The primary pillars to prevent EVD are: early diagnosis, isolation of patients, contact tracing and monitoring, safe burials, infection prevention and control and social mobilization. The implementation of all these components was challenged in the field. Key lessons from this Ebola outbreak are that countries with weak health care systems can't withstand the major outbreaks; preparedness to treat the first confirmed cases is a national emergency; all control measures must be coordinated together and community engagement is the great factor to combat this disease.

  4. Collision physics going west

    Anon.

    1988-01-01

    The centroid of proton-antiproton physics is moving west across the Atlantic concluded Luigi Di Leila of CERN in his summary talk at the Topical Workshop on Proton-Antiproton Collider Physics, held at Fermilab in June. Previous meetings in this series had been dominated by results from CERN's big proton-antiproton collider, dating back to 1981. However last year saw the first physics run at Fermilab's collider, and although the number of collisions in the big CDF detector was only about one thirtieth of the score so far at CERN, the increased collision energy at Fermilab of 1.8 TeV (1800 GeV, compared to the routine 630 GeV at CERN) is already paying dividends

  5. West Germany's nuclear dilemma

    Dangelmayer, D.

    1978-01-01

    The US 1978 Nuclear Non-Proliferation Act legislated the embargo of enriched uranium supplies from that country to any other country which would not agree to tighter restrictions on a wide variety of their nuclear activities, including the reprocessing of spent uranium to provide separated plutonium. This has resulted in a three month supply cut-off to the EEC countries. However the EEC is now willing to renegotiate supply contracts with the US to accord with the tighter safeguards set down in the Act. Effectively both sides now have an 18 month breathing space for them to seek a compromise on the non-proliferation question. The effect of these strategies on West Germany's energy policy, which seeks to become increasingly energy self-sufficient through the use of nuclear fuel reprocessing and the fast reactor, is discussed.

  9. Alien smuggling: East to West.

    Walsh, J H

    1987-01-01

    This year untold millions of illegal aliens will enter Western Europe, Canada, and the US; in 1986, the US alone made 1.7 million apprehensions. Because of the numbers involved and the hard currency exchanged, alien smuggling has become big business--a lucrative track in desparate human beings. West Germany's open door asylum policy has been a boon to the smugglers, and West Berlin is currently a favored port of entry. The government provides social benefits--apartments, food, a stipend, and clothing--for asylum seekers. Smuggling operations appear to fit 3 categories: 1) state-sponsored alien smugglers, with a sub-category of terrorists; 2) ethnic smugglers with a history of terrorist spinoffs; and 3) independent smugglers, who are profit oriented, and willing to handle ethnic aliens and terrorists. In West Germany, immigration investigations begin at the border. West German officials often know that as they cause the Eastern border to be tightened, the flow will gravitate south toward Austria. Redirecting the trasit of Third Worlders from East Berlin away from West Germany, Sweden, and Denmark will be a stop-gap measure at best. Part of West Germany's immigration problem can be traced to the Basic Law that provides asylum for those who claim persecution (political, racial, ethnic, or religious). Yet, any attempt to change asylum would result in an admission of defeat in the quest for a unified Germany. Should Austria move to tighten its immigration laws, agreements similar to those between East and West Germany will likely follow.

  10. Trade networks in West Africa

    2014-01-01

    To date, most of the literature on trade networks in West Africa has considered networks in a metaphorical way. The aim of this paper is to go one step further by showing how social network analysis may be applied to the study of regional trade in West Africa. After a brief review of the literature......, this exploratory paper investigates two main issues related to regional trade. We start by discussing how recent developments in regional trade in West Africa have contributed to challenging the social structure of traders. We then discuss the changes that have affected the spatiality of regional trade by looking...

  13. "I'm Managing My Diabetes between Two Worlds": Beliefs and Experiences of Diabetes Management in British South Asians on Holiday in the East--A Qualitative Study.

    Patel, Neesha R; Kennedy, Anne; Blickem, Christian; Reeves, David; Chew-Graham, Carolyn

    2016-01-01

    Diabetes is disproportionately high among British South Asians compared to the general UK population. Whilst the migrant British South Asians group has received most attention on research related to diabetes management, little consideration has been given to impact of travel back to the East. This study aimed to explore the role of social networks and beliefs about diabetes in British South Asians, to better understand their management behaviours whilst holidaying in the East. Semistructured interviews were conducted in Greater Manchester. Forty-four participants were recruited using random and purposive sampling techniques. Interviews were analysed thematically using a constant comparison approach. Migrant British South Asians expressed a strong preference to be in a hot climate; they felt they had a healthier lifestyle in the East and often altered or abandoned their diabetes medication. Information acquisition on diabetes and availability of social networks in the East was valued. Social networks in the East are a valued source of information and support for diabetes. The lack of adherence to medication whilst abroad suggests that some migrant British South Asians have a poor understanding of diabetes. Future research needs to explore whether patients are seeking professional advice on diabetes management prior to their extended holiday.

  14. [Prospective study on the effect of the influence of holiday periods in the weight during a low-calory dietetic treatment].

    García, Cándido Gabriel; Berná, Amparo; Sebastià, Natividad; Soriano, José Miguel

    2013-11-01

    Overweight and obesity are both in Europe and in Spain, one of the major public health problems since they are associated with cardiovascular risk factors and the occurrence of other diseases. Nowadays, the prevalence of obesity SEEDO in Spanish society is about 25%. In addition to evaluating how our lifestyle habits influence in our weight, it would be interesting to assess how the festivity days, which in many cases are often extended beyond officially holidays, can influence the total annual weight gain. A prospective and descriptive study was conducted in a total of 258 patients (95 men and 163 women) undergoing a treatment for weight reduction, at least during one month ago. We studied seven holiday periods. In all patients, there was a significant linear correlation (p < 0.05) difference between weight loss and vacational time studied with greater prevalence in the Christmas period. No statistically significant association was found between weight loss and age or sex. Copyright AULA MEDICA EDICIONES 2013. Published by AULA MEDICA. All rights reserved.

  15. Travel and the ecological footprint in 2005. Environmental load of holidays by people in the Netherlands; Reizen op grote voet in 2005. De milieubelasting van vakanties van Nederlanders

    This report presents the results of a study of the environmental load of Dutch people going on holiday. The environmental load is expressed as the 'ecological footprint', a measure for the environmental space and the carbon footprint, i.e. the CO2 emissions that are responsible for climatic change. The research shows that the holidays of Dutch people account for a share of 7.3% of the ecological footprint of the Netherlands and for 7.9% of all CO2 emissions. The differences between various kinds of travel are wide, though [mk]. [Dutch] Het rapport bevat de resultaten van een onderzoek naar de milieubelasting van de Nederlandse vakantieganger. De milieubelasting wordt uitgedrukt in de 'ecologische voetafdruk', een maat voor de milieugebruiksruimte, en de 'carbon footprint', ofwel de emissies van kooldioxide die verantwoordelijk zijn voor klimaatverandering. Uit het onderzoek blijkt dat de Nederlandse vakantieganger verantwoordelijk is voor 7,3% van de ecologische voetafdruk van Nederland en 7,9% van de CO2-emissies. De verschillen tussen verschillende reizen zijn echter groot.

  16. Why the West?

    2009-03-01

    Full Text Available La cuestión de cómo "Occidente" llegó a dominar el mundo durante la era moderna se ha debatido recientemente entre los historiadores. El debate se ha polarizado entre quienes ven en la "modernidad" como resultado de un 'milagro', el proceso cultural único generado en el seno del mismo Occidente, y aquellos que cuestionan este "milagro" como paradigma eurocéntrico, y buscan otros factores para entender y explicar el dominio occidental del mundo económico y político. La literatura tradicional, representada por David Landes en su reciente “La riqueza y la pobreza de las naciones”, atribuye el éxito europeo a sus valores culturales únicos, a sus instituciones sociales y sus prácticas políticas. Este éxito fue completamente "impulsado desde dentro” por estas características. Recientemente, varios historiadores han cuestionado este "paradigma del milagro" como eurocéntrica, y miran a otros factores para comprender y explicar el dominio occidental del mundo económico y político. Después de examinar los recientes trabajos de los historiadores frente a este problema, este artículo trata de colocar la expansión europea en un contexto global, y la comprensión de la Revolución Industrial como una transformación global. Esta perspectiva nos permite entender los cambios tecnológicos y económicos Europeos en el contexto más amplio de patrones de interacción económica y cultural de todo el mundo._____________ABSTRACT:The question of how 'the West' came to dominate the globe during the modern era has been debated recently among historians. The debate has been polarized between those who view 'modernity' as the result of a 'European miracle', the culturally unique and internally generated project of the West, and those who question this 'European miracle' paradigm as Eurocentric, and look to other factors to understand and explain Western economic and political world dominance.

    The number of holiday kilometres is growing rapidly and appears practically immune for issues such as rising fuel costs, economic recessions and even terrorist attacks such as 9/11. We go more often and travel further away: in 1969 we took 7 million long holidays with 8 billion travelling kilometres. These numbers increased to 20 million holidays and 60 billion travelling kilometres in 2005. This was established in an analysis of TNS NIPO, by request of the Netherlands Environmental Assessment Agency (MNP). MNP uses the results for a sustainability survey in which future developments are focused upon. According to trendlines, this growth will even continue spectacularly towards 40 million holidays with 160 billion travelling kilometres in 2040. By then, the Dutch population will go on holiday three times a year and fly more often: 1300 km per person currently to 6000 km in 2040. Levies proposed in the coalition agreement may be able to put a brake on this growth. Holiday traffic by airplane is already responsible for 2.5 percent of our total CO2 emissions. This is twice the share of car traffic for holiday purposes. The CO2 emissions of airplanes amount to approximately 200 gramme equivalents per traveller kilometer (approximately 125 grammes per traveller kilometre for passenger cars). This may decrease by 30 to 40% in the future by using larger and more efficient airplanes, but this will not be enough to compensate for the volume growth. CO2 emissions are expected to triple if policy remains unaltered and levies are not increased.(mk) [Dutch] Het aantal vakantiekilometers groeit zeer snel en blijkt praktisch immuun voor zaken als stijgende brandstofprijzen, economische recessies en zelfs voor aanslagen zoals 9/11.

  19. On the Confession of a Canary Bird, Children on a Holiday Camp, and the Apology for Fleas Planned by Janusz Korczak

    Agnieszka Zgrzywa

    2013-01-01

    Full Text Available The point of departure for this article is the memory of moving fragments of Janusz Korczak’s journal from Warsaw ghetto. The author confronts the fragments with Korczak’s earlier texts, such as the short storied about holiday camps for Polish and Jewish children, and the novel Król Maciuś na bezludnej wyspie [King Maciuś on a Desert Island]. The image of a canary bird, used in the novel, is confronted with other symbolic stories about this bird, such as the story in Wiesław Myśliwski’s Pałac [Palace]. With reference to the image, the article invokes Korczak’s meditations on identity and tolerance, and human ethical and aesthetic choices. The audacity of Korczak’s thoughts and conclusions goes far beyond his time, and seems perfectly fit for ours.
