    2010-01-01

    Excessive tanning appears to be evident in about one quarter of regular sunbathers. Susceptible individuals are likely to be young Caucasians from Western societies. Despite ongoing education by the media to the public about the risks of excessive exposure to ultraviolet radiation and the availability of potent sunscreens, there seems to be a concurrent proliferation of tanning facilities. What might be potential psychological explanations for excessive or pathological tanning? Psychopathological explanations may exist on both Axes I and II and include substance use, obsessive-compulsive, body dysmorphic, and borderline personality disorders. While there is no known treatment for pathological sunbathing, we discuss several treatment interventions from the literature that have been successfully used for the general public. PMID:20622941

    Indoor tanning (IT), particularly during early adulthood, increases risk for melanoma and is exceedingly common among youth. Social influence, including social norms, promotes IT but little is known about young adults' engagement with friends around tanning. We examined IT behaviors and tanning-related communication with friends at three universities. Of 837 participants, 261 (31%) reported ever tanning (90% female, 85% White). Of those, 113 (43%) were former tanners and 148 (57%) current tanners. Current tanners reported more social tanning and discussions with friends about tanning, more frequent outdoor tanning, high propensity to tan, and greater lifetime IT exposure than former tanners. Risks-to-benefits discussion ratios were greater for former tanners. In adjusted analyses, current tanners were more likely to make plans to tan and to talk about tanning benefits with friends. Findings confirm IT is a social experience. Future work should examine social tanning's role in the promotion and reduction of IT among youth.

    2009-01-01

    Background The pigment melanin is produced by specialized cells, called melanocytes. In healthy skin, melanocytes are sparsely spread among the other cell types in the basal layer of the epidermis. Sun tanning results from an UV-induced increase in the release of melanin to neighbouring keratinocytes, the major cell type component of the epidermis as well as redistribution of melanin among these cells. Here we provide a mathematical conceptualization of our current knowledge of the tanning response, in terms of a dynamic model. The resolution level of the model is tuned to available data, and its primary focus is to describe the tanning response following UV exposure. Results The model appears capable of accounting for available experimental data on the tanning response in different skin and photo types. It predicts that the thickness of the epidermal layer and how far the melanocyte dendrites grow out in the epidermal layers after UV exposure influence the tanning response substantially. Conclusion Despite the paucity of experimental validation data the model is constrained enough to serve as a foundation for the establishment of a theoretical-experimental research programme aimed at elucidating the more fine-grained regulatory anatomy underlying the tanning response.

  8. Magazine exposure, tanned women stereotypes, and tanning attitudes.

    PubMed

    Cho, Hyunyi; Lee, Seungyoon; Wilson, Kari

    2010-09-01

    This study investigated whether magazine exposure is related to stereotypical beliefs about tanned women. A survey of White college women (n=205) assessed their exposure to beauty/fashion and health/fitness magazines. Outcome variables were the beliefs that tanned women are fashionable, fit, and shallow. Attention to the tanned women's images in health magazines positively predicted the belief that tanned women are fit and that tanned women are shallow; in contrast, attention to the images in beauty magazine negatively predicted the belief that tanned women are fit. Number of beauty magazines women read negatively predicted the belief that tanned women are shallow. The belief that tanned women are fit was unrelated, but the belief that tanned women are shallow was negatively related, with tanning attitudes.

    Objectives The study's purpose was to investigate the association of contextual factors such as cost, tanning accessibility, regulations, or marketing and indoor tanning or tanning dependence. Methods One hundred thirty-nine college-aged female indoor tanners completed a questionnaire between 2009 and 2011. Results Higher scores on tanning dependence and assessment in the spring/summer (versus the fall/winter) were associated with more frequent indoor tanning in the last 30 days (ps < .05). More frequent indoor tanning, greater session length, and more trouble paying for tanning were associated with higher scores on tanning dependence (ps < .05). Conclusions Public health research and practice could benefit from attention to such contextual factors as tanning cost and regulations regarding session length. PMID:25741682

    The use of tanning booths as a substitute for natural sunlight is becoming increasingly popular. However, unless careful attention is paid to proper design and maintenance, the radiation field inside a tanning booth can be highly anisotropic. The use of simple, inexpensive ultraviolet radiation meters to measure dosage can lead to serious overexposure. Since the ultraviolet radiation inside a tanning booth has a greater proportion of short wavelengths (less than 300 nanometers) than natural sunlight, the amount of skin cancer-inducing radiation received for a tan may be twice that received for a natural suntan.

    2015-01-01

    Exposure to ultraviolet radiation from indoor tanning device use is associated with an increased risk of skin cancer, including risk of malignant melanoma, and is an urgent public health problem. By reducing indoor tanning, future cases of skin cancer could be prevented, along with the associated morbidity, mortality, and healthcare costs. On August 20, 2012, the CDC hosted a meeting to discuss the current body of evidence on strategies to reduce indoor tanning as well as research gaps. Using the Action Model to Achieve Healthy People 2020 Overarching Goals as a framework, the current paper provides highlights on the topics that were discussed, including (1) the state of the evidence on strategies to reduce indoor tanning; (2) the tools necessary to effectively assess, monitor, and evaluate the short- and long-term impact of interventions designed to reduce indoor tanning; and (3) strategies to align efforts at the national, state, and local levels through transdisciplinary collaboration and coordination across multiple sectors. Although many challenges and barriers exist, a coordinated, multilevel, transdisciplinary approach has the potential to reduce indoor tanning and prevent future cases of skin cancer. PMID:23683986

  14. Internet advertising of artificial tanning in Australia.

    2006-08-01

    Artificial tanning, defined as deliberate exposure to ultraviolet rays produced by artificial tanning devices, is a new and emerging public health issue in Australia and globally. Epidemiological research suggests that artificial tanning may contribute to the incidence of melanoma, nonmelanoma skin cancer as well as other health problems. Given that Australia has a high incidence of skin cancer, we have undertaken a study to explore how artificial tanning has been promoted to its users. The aim was to analyze the completeness and accuracy of information about artificial tanning. A content analysis of web sites of tanning salons and distributors of tanning equipment in Australia was conducted. A total of 22 web sites were analyzed. None of the solarium operators or distributors of equipment provided full information about the risks of artificial tanning. Fifty-nine percent of web advertisements had no information and 41% provided only partial information regarding the risks of artificial tanning. Pictures with the image of bronze-tanned bodies, predominantly women, were used by all web advertisers. In light of the success of sun-safety campaigns in Australia, the findings of future epidemiological research on the prevalence of artificial tanning and sociological and anthropological research on why people utilize artificial tanning should be a basis for developing effective targeted health promotion on the elimination of artificial tanning in the country.

    The purpose of this study to examine support for indoor tanning policies and correlates of policy support among young adult women who indoor tan. Non-Hispanic white women ages 18-30 who indoor tanned in the past year (n = 356, M 23.3 age, SD 3.1) recruited in the Washington, DC area from 2013 to 2016 completed measures of indoor tanning behaviors, attitudes, perceptions, beliefs, and policy support. Most women in the sample supported policies to prevent children under the age of 18 from indoor tanning (74.0 %) and stronger warnings about the risks of indoor tanning on tanning devices (77.6 %); only 10.1 % supported a total ban. In multivariable analyses, support for individual indoor tanning policies varied by demographics (e.g., age), frequent indoor tanning behavior, indoor tanning beliefs, and risk perceptions. Non-Hispanic white young adult women who indoor tan, the primary consumers of indoor tanning, and a high-risk population, largely support indoor tanning prevention policies implemented by many state governments and those currently under review for national enactment. Given low levels of support for a total indoor tanning ban, support for other potential policies (e.g., increasing the minimum age to 21) should be investigated to inform future steps to reduce indoor tanning and the associated health risks.

    2014-03-01

    The tanning response, classically defined as increased cutaneous pigmentation after solar ultraviolet light exposure, encompasses a variety of protective, reparative, and cosmetic issues. The tanning story is continuously evolving as basic science, clinical research, and public health studies shed light on topics involving: the physiologic mechanisms of tanning, the medical benefits of tanning, the role of sunscreens, the development of "sunless" self-tanners, the use of photocarcinogenic indoor tanning services, and the relatively recent development and promulgation of α-melanocyte-stimulating hormone analogues. High-risk tanning behaviors have become increasingly popular and the incidence of melanoma has risen more rapidly than any other cancer. This review will focus on the risks and benefits of each type of tanning, with an emphasis on issues pertinent to dermatologists who care for adolescents and young adults.

    2015-04-01

    Identification of risk factors for indoor tanning may ultimately aid the development of better indoor tanning prevention strategies, which is pertinent given the association between indoor tanning and skin cancer. This study aimed to examine the relationship between seasonal sleep change and indoor tanning. Female tanners (N=139) completed self-report measures including items relating to seasonal sleep changes, seasonal affective disorder (SAD), reasons for tanning, tanning during the winter months, and the Tanning Pathology Scale (TAPS), which measures problematic tanning motives and symptoms of tanning dependence. It was hypothesized that seasonal sleep change and SAD would be associated with greater indoor tanning during the winter, more tanning to improve mood and to relax, and higher scores on the TAPS. Findings indicated that more seasonal sleep change was associated with tanning to improve mood and higher scores on the TAPS. Similarly, the presence of SAD was related to tanning to improve mood, tanning to relax, and more problematic tanning.

    Tanning during adolescence increases skin cancer risk. Relatively few studies have examined the association between thinness attitudes and tanning attitudes and behaviors. The purpose of the current study was to examine psychosocial predictors of sunbathing and tanning bed use, specifically thin ideal internalization (TII) and motives for tanning among high school girls. Adolescent girls (N = 229) completed a 10-minute questionnaire designed to assess sunbathing and indoor tanning, TII and motives to tan (appearance, social and well-being). Hierarchical regression analyses showed that TII, β = .05, p < .05, appearance motives, β = .11, p < .01 and well-being motives, β = .11, p < .01 were all independently positively associated with sunbathing. Social motives were negatively associated with sunbathing, β = -.07, p < .05. A three-way interaction was found between the three types of motives on indoor tanning, in that appearance and well-being motives interacted to increase indoor tanning levels, especially among those who strongly endorsed social motives for tanning, β = .22, p < .05. Motives for tanning, specifically those associated with appearance and well-being, can interact to increase tanning bed use. When designing tailored interventions for skin cancer prevention in young people, researchers should consider tailoring based on motivation. Researchers and healthcare professionals who work with adolescents should attend to tanners who are motivated for both appearance and mood-related reasons, as they may be most at risk for tanning dependence and skin cancer.

  20. Toward quantifying the abuse liability of ultraviolet tanning: A behavioral economic approach to tanning addiction.

    2016-07-01

    Many adults engage in ultraviolet indoor tanning despite evidence of its association with skin cancer. The constellation of behaviors associated with ultraviolet indoor tanning is analogous to that in other behavioral addictions. Despite a growing literature on ultraviolet indoor tanning as an addiction, there remains no consensus on how to identify ultraviolet indoor tanning addictive tendencies. The purpose of the present study was to translate a behavioral economic task more commonly used in substance abuse to quantify the "abuse liability" of ultraviolet indoor tanning, establish construct validity, and determine convergent validity with the most commonly used diagnostic tools for ultraviolet indoor tanning addiction (i.e., mCAGE and mDSM-IV-TR). We conducted a between-groups study using a novel hypothetical Tanning Purchase Task to quantify intensity and elasticity of ultraviolet indoor tanning demand and permit statistical comparisons with the mCAGE and mDSM-IV-TR. Results suggest that behavioral economic demand is related to ultraviolet indoor tanning addiction status and adequately discriminates between potential addicted individuals from nonaddicted individuals. Moreover, we provide evidence that the Tanning Purchase Task renders behavioral economic indicators that are relevant to public health research. The present findings are limited to two ultraviolet indoor tanning addiction tools and a relatively small sample of high-risk ultraviolet indoor tanning users; however, these pilot data demonstrate the potential for behavioral economic assessment tools as diagnostic and research aids in ultraviolet indoor tanning addiction studies.

    Tanning in the United States has become an increasingly popular activity in our culture. Tanning methods have evolved through the years to become more readily accessible and easier to use for all consumers, regardless of geographic location. With the rising incidence of skin cancer, the demand for safe and efficient tanning methods remains high. There are currently many different tanning methods being utilized, and still more are being researched. This article serves to summarize some of the most common tarining methods used in the United States today as well as some potential methods currently under study. PMID:25741402

    This study investigated the attitudes of body-tanning behaviors: suntanning, tanning bed, tanning spray, and sunless tanning product use. Data collected from 208 female college students (M age = 19.8 yr., SD = 2.0; M weight = 63.3 kg, SD = 2.0; M height = 165.9 cm, SD = 8.1) online. The questionnaire comprised four constructs: appearance-based, health-based, and emotion-based tanning attitudes, and body-tanning behaviors. Both appearance-based and emotion-based pro-tanning attitudes were associated with significantly higher body-tanning behaviors. However, health-based pro-tanning attitudes did not significantly affect body-tanning behaviors. The results from both UV- and non-UV exposure-related tanning behaviors provide future intervention strategies, such as establishing a positive body image without a tan and identifying negative emotional consequences as a result of tanning.

    Tanning increases dramatically through the teenage years, but the family context of this health risk behavior is relatively unstudied. We conducted videotaped conversations between teenage girls (10th and 11th grade) and their mothers. We developed a coding system for discussion content and highlight findings including inadequate knowledge concerning the harms of tanning and positive views of outdoor tanning over indoor tanning, yet agreement that all tans are attractive. Many teens believed that indoor tanning is sometimes necessary to achieve the tanned look. These findings can usefully guide intervention development regarding the harms of all tanning, rather than indoor or outdoor tanning specifically.

    There is no research investigating indoor tanning advertising on social media. We assessed the use of social media to promote indoor tanning. We subscribed to social media platforms in six US cities and content-analyzed promotional messages received. We captured 662 messages on Twitter and Facebook, through salon emails, and in daily deal coupons. Salon postings were most frequent on Twitter and Facebook, with an average of 2-3 postings per week. National chains posted more frequently than local businesses. Forty percent of messages were devoid of tanning content and included photos, jokes, or popular references. Thirty percent mentioned price reductions, and 28 % referenced an upcoming holiday. Sunless tanning (17 %) was promoted more often than ultraviolet tanning (9 %). Tanning salons actively use social media as a strategy for maintaining relationships with customers and offer pricing deals that promote loyalty and high-frequency tanning.

    2014-06-01

    Excessive indoor tanning, defined by the presence of an impulse towards and repetition of tanning that leads to personal distress, has only recently been recognized as a psychiatric disorder. This finding is based on the observations of many dermatologists who report the presence of addictive relationships with tanning salons among their patients despite being given diagnoses of malignant melanoma. This article synthesizes the existing literature on excessive indoor tanning and addiction to investigate possible associations. This review focuses on the prevalence, clinical features, etiology, and treatment of this disorder. A literature review was conducted, using PubMed, Google Scholar, EMBASE and PsycINFO, to identify articles published in English from 1974 to 2013. Excessive indoor tanning may be related to addiction, obsessive-compulsive disorder, impulse control disorder, seasonal affective disorder, anorexia, body dysmorphic disorder, or depression. Excessive indoor tanning can be included in the spectrum of addictive behavior because it has clinical characteristics in common with those of classic addictive disorders. It is frequently associated with anxiety, eating disorders, and tobacco dependence. Further controlled studies are required, especially in clinical psychopathology and neurobiology, to improve our understanding of excessive indoor tanning.

    The practice of indoor tanning has led to the development of a large artificial tanning industry. In addition to psychological benefits, exposure to UVB light helps the body produce the activated form of vitamin D, which is necessary for many cellular functions. But uncontrolled tanning and UV overexposure can increase the risk of skin cancer. For direct checkout of the vitamin D synthetic capacity of a UV source the bio-equivalent UV dosimeter has been developed that is based on the same molecular photochemistry from which vitamin D is photosynthesized in human skin and makes possible both instrumental and visual indication of vitamin D synthesis.

    To establish adolescent tanning beliefs and behaviors, prevalence and location of UV tanning device (beds/lamps) use, awareness of risk and restriction signage, and frequency of tanning service refusal, noting differences by grade and sex, prior to a ban on UV tanning device use among those under 18 in Ontario, Canada. Data were collected May 5 to 20 of 2014. Children in grades 7 to 12, and under age 18 completed an on-line questionnaire that asked their age, sex, grade, methods used to tan, frequency, length and location of UV tanning device use, if services were refused and why, awareness and content of signs/warning labels, tanning beliefs and knowledge, and use of eye protection. Of 1561 participants (10% response rate), 49% were male, 51% female. There were significant differences between the sexes regarding tanning behaviors (e.g. not tanning, tanning outside). Seven percent (108) had 'ever' used UV tanning devices, females more than males (p=0.0026). Over half (57%) of the 104 using UV tanning devices in the past 12months noticed warning signs/labels, of which most noticed that UV tanning devices can cause cancer (65%), and that UV exposure can contribute to premature aging (67%). While most (66%) tanned at tanning salons/studios and beauty salons/studios, gyms/fitness clubs (35%) and home use were common (25%). A relatively low proportion of adolescents used UV tanning devices prior to the ban, with use more common among females and those in higher grades.

  18. Solar wind tans young asteroids

    NASA Astrophysics Data System (ADS)

    2009-04-01

    A new study published in Nature this week reveals that asteroid surfaces age and redden much faster than previously thought -- in less than a million years, the blink of an eye for an asteroid. This study has finally confirmed that the solar wind is the most likely cause of very rapid space weathering in asteroids. This fundamental result will help astronomers relate the appearance of an asteroid to its actual history and identify any after effects of a catastrophic impact with another asteroid. ESO PR Photo 16a/09 Young Asteroids Look Old "Asteroids seem to get a ‘sun tan' very quickly," says lead author Pierre Vernazza. "But not, as for people, from an overdose of the Sun's ultraviolet radiation, but from the effects of its powerful wind." It has long been known that asteroid surfaces alter in appearance with time -- the observed asteroids are much redder than the interior of meteorites found on Earth [1] -- but the actual processes of this "space weathering" and the timescales involved were controversial. Thanks to observations of different families of asteroids [2] using ESO's New Technology Telescope at La Silla and the Very Large Telescope at Paranal, as well as telescopes in Spain and Hawaii, Vernazza's team have now solved the puzzle. When two asteroids collide, they create a family of fragments with "fresh" surfaces. The astronomers found that these newly exposed surfaces are quickly altered and change colour in less than a million years -- a very short time compared to the age of the Solar System. "The charged, fast moving particles in the solar wind damage the asteroid's surface at an amazing rate [3]", says Vernazza. Unlike human skin, which is damaged and aged by repeated overexposure to sunlight, it is, perhaps rather surprisingly, the first moments of exposure (on the timescale considered) -- the first million years -- that causes most of the aging in asteroids. By studying different families of asteroids, the team has also shown that an asteroid

    2014-01-01

    We examined adolescents' reasons for tanning and how these relate to appearance evaluation and orientation. Two hundred and sixty-four Canadian adolescents (age range 15-19 years) in grades 10, 11, and 12 completed a survey that included scales measuring their reasons for tanning, appearance evaluation, and appearance orientation. It was found that girls and boys differed on four of nine subscales measuring reasons for tanning. Girls believed more strongly than boys that tanning improved their general appearance and that friends influenced their decision to tan. Girls also expressed less concern than boys that tanning caused immediate skin damage or premature aging. The pattern of correlations between the reasons for tanning and appearance orientation was similar for girls and boys. For both, appearance reasons for tanning and sociocultural influences on tanning were positively associated with appearance orientation. Suggestions for future research with adolescents and a proposal for a guiding model are provided.

  1. Does the portrayal of tanning in Australian women's magazines relate to real women's tanning beliefs and behavior?

    2011-04-01

    Content analysis data on the tans of 4,422 female Caucasian models sampled from spring and summer magazine issues were combined with readership data to generate indices of potential exposure to social modeling of tanning via popular women's magazines over a 15-year period (1987 to 2002). Associations between these indices and cross-sectional telephone survey data from the same period on 5,675 female teenagers' and adults' tanning attitudes, beliefs, and behavior were examined using logistic regression models. Among young women, greater exposure to tanning in young women's magazines was associated with increased likelihood of endorsing pro-tan attitudes and beliefs. Among women of all ages, greater exposure to tanned models via the most popular women's magazines was associated with increased likelihood of attempting to get a tan but lower likelihood of endorsing pro-tan attitudes. Popular women's magazines may promote and reflect real women's tanning beliefs and behavior.

    The Gamma-ray Coordinates Network / Transient Astronomy Network (GCN/TAN) is your one-stop shopping place for all transient astronomy. It collects nearly all the astrophysical transients from the missions (space-based and ground-based), puts them into a standard format, and distributes them to whomever wishes to receive them. This is all done autonomously (completely autonomous within GCN/TAN, and almost always autonomously within the producer end of operations). This automation means minimal time delays (<0.1 sec within GCN for socket-based distribution methods, and up to 30 sec for email-based which is dependant on the internet email protocol and the number of hops (both of which are out of the control of GCN/TAN). A status report on the current set of sources of transient information, plus recently-added and soon-to-be-added source will be given. Also, a standing request for GCN/TAN to incorporate your transient data stream; plus instruction for customers to receive GCN/TAAN Notice and Circular information.

    For the first time, the 2013 Colorado Youth Risk Behavior Survey assessed indoor tanning practices of Colorado high school students. The survey revealed that girls are more likely to use indoor tanning devices than boys and that the majority of students who tan do so once or twice annually. Health care professionals and policymakers should focus on these groups in efforts to curtail indoor tanning and the associated risk of skin cancer in youth.

    2015-01-01

    The incidence of melanoma has been increasing over the past several decades, with notable increases in the pediatric and adolescent population. Indoor tanning has been proven carcinogenic and is associated with an increased risk of melanoma, especially when used at a young age. The incidence and frequency of usage of indoor tanning in the United States is high, particularly among adolescents, with roughly 20% reporting using a tanning bed at least once. The Food and Drug Administration recently made changes to its regulation of indoor tanning devices, reclassifying them as class II devices necessitating stricter premarket review, and strengthened its warnings for these devices; however, federal regulation of indoor tanning is still limited and most regulation of indoor tanning in minors is done on a state-by-state basis. Three types of legislation exist: (1) absolute ban on minor use of indoor tanning devices, (2) age restriction of minor usage of indoor tanning devices other than age 18 years, and (3) requirement of parental consent. These regulations are inconsistent, and enforcement efforts are often limited. In this contribution, we provide an update on the prevalence of indoor tanning, the risks associated with indoor tanning, and the current federal and state legislation and enforcement efforts in the United States with regard to indoor tanning. Although efforts are being made to ban all use of indoor tanning devices by minors, there is still more work to be done before this becomes a reality in the United States.

    2013-01-01

    In October 2011, California became the first US state to ban indoor tanning for minors under age 18 years. Vermont followed in May 2012. Increasingly, scientific evidence shows that artificial tanning raises the risk of skin cancer, including melanoma, a common cancer in adolescents and young adults and the type most likely to result in death. The World Health Organization, the American Academy of Pediatrics, the American Academy of Dermatology, the American Medical Association, and other organizations strongly recommend legislation to ban minors under age 18 from indoor tanning. Several nations have banned teen tanning. Yet, tanning in salons is still a prevalent practice in the United States, especially among teen girls, where rates for the oldest teens approach 40%. There is no federal legislation to restrict minors from salon tanning. More than 60% of states have some kind of legislation regarding minors’ use of tanning salons, but only California and Vermont have passed complete bans of indoor tanning for minors. The Indoor Tanning Association, an industry advocacy group, has vigorously opposed legislative efforts. Pediatricians can play key roles in counseling families and with legislative efforts. In this update, we review the prevalence of salon tanning, association with skin cancer risk, tanning addiction, the roles of the federal and state governments in regulation and legislation, and responses to arguments created by industry to oppose legislation. Preventing exposure to artificial tanning may save lives, including young lives, and is a key cancer prevention opportunity for pediatricians. PMID:23509165

    In order to better understand drivers of dangerous indoor tanning behaviors, researchers developed the Comprehensive Indoor Tanning Expectations scale. To examine the longitudinal effectiveness of Comprehensive Indoor Tanning Expectations, we surveyed young women in the Southeastern United States at two time points (N = 553). The scale demonstrated strong test-retest reliability. Participants who believed indoor tanning would improve their mood and afford social approval were significantly more likely to tan 6 months later, while participants who believed indoor tanning leads to psychological/physical discomfort were significantly less likely to tan 6 months later. Knowing the psychological bases for indoor tanning can inform intervention and message design.

  16. GCN/TAN -- Current and Future Functionality

    Barthelmy, Scott D.

    2013-04-01

    The Gamma-ray Coordinates Network / Transient Astronomy Network (GCN/TAN) has been operating for 20 years. It collects all the detections of GRBs and other astrophysical transients (positions and times) and distributes that information to nearly all the observers and instruments around the world; all done automatically, with minimal time delays (seconds in most cases). In recent years several non-GRB-producing data streams have been added (gravitational lensing events from MOA and flares from AGN, novae, flare stars, etc from the Fermi, MAXI and Swift missions). And to facilitate cross-instrument temporal and spatial correlations, GCN/TAN has been modified (a) to identify in real time these correlations as the notices are distributed, and (b) producing "sub-threshold" streams from the Swift and INTEGRAL missions. The later allows other instruments (ground and flight; eg ICECUBE, and in the future aLIGO) to make correlations that would then raise the confidence level of these sub-threshold detections. These temporal/spatial correlations will be expanded to include mission-based data sets that are not real-time (ie hours to days delayed). Three VOEvent servers have been added to distribute the entire set of GCN/TAN notices in that format and method.

  17. Ultrasound assisted chrome tanning: Towards a clean leather production technology.

    2016-09-01

    Nowadays, there is a growing demand for a cleaner, but still effective alternative for production processes like in the leather industry. Ultrasound (US) assisted processing of leather might be promising in this sense. In the present paper, the use of US in the conventional chrome tanning process has been studied at different pH, temperature, tanning time, chrome dose and US exposure time by exposing the skin before tanning and during tanning operation. Both prior exposure of the skin to US and US during tanning improves the chrome uptake and reduces the shrinkage significantly. Prior exposure of the skin to US increase the chrome uptake by 13.8% or reduces the chrome dose from 8% to 5% (% based on skin weight) and shorten the process time by half while US during tanning increases the chrome uptake by 28.5% or reduces the chrome dose from 8% to 4% (half) and the tanning time to one third compared to the control without US. Concomitantly, the resulting leather quality (measured as skin shrinkage) improved from 5.2% to 3.2% shrinkage in the skin exposed to US prior tanning and to 1.3% in the skin exposed to US during the tanning experiment. This study confirms that US chrome tanning is an effective and eco-friendly tanning process which can produce a better quality leather product in a shorter process time with a lower chromium dose.

  18. Volcanic geomorphology using TanDEM-X

    Poland, Michael; Kubanek, Julia

    2016-04-01

    Topography is perhaps the most fundamental dataset for any volcano, yet is surprisingly difficult to collect, especially during the course of an eruption. For example, photogrammetry and lidar are time-intensive and often expensive, and they cannot be employed when the surface is obscured by clouds. Ground-based surveys can operate in poor weather but have poor spatial resolution and may expose personnel to hazardous conditions. Repeat passes of synthetic aperture radar (SAR) data provide excellent spatial resolution, but topography in areas of surface change (from vegetation swaying in the wind to physical changes in the landscape) between radar passes cannot be imaged. The German Space Agency's TanDEM-X satellite system, however, solves this issue by simultaneously acquiring SAR data of the surface using a pair of orbiting satellites, thereby removing temporal change as a complicating factor in SAR-based topographic mapping. TanDEM-X measurements have demonstrated exceptional value in mapping the topography of volcanic environments in as-yet limited applications. The data provide excellent resolution (down to ~3-m pixel size) and are useful for updating topographic data at volcanoes where surface change has occurred since the most recent topographic dataset was collected. Such data can be used for applications ranging from correcting radar interferograms for topography, to modeling flow pathways in support of hazards mitigation. The most valuable contributions, however, relate to calculating volume changes related to eruptive activity. For example, limited datasets have provided critical measurements of lava dome growth and collapse at volcanoes including Merapi (Indonesia), Colima (Mexico), and Soufriere Hills (Montserrat), and of basaltic lava flow emplacement at Tolbachik (Kamchatka), Etna (Italy), and Kīlauea (Hawai`i). With topographic data spanning an eruption, it is possible to calculate eruption rates - information that might not otherwise be available

  19. Community variation in adolescent access to indoor tanning facilities.

    2013-04-01

    Melanoma rates among younger women in New Hampshire (NH) are rising. In urban studies, youth proximity to tanning facilities has been linked to indoor tanning, a proven cause of melanoma. Youth access has not been examined in rural settings. To determine on a statewide basis the influence of rurality and community income level on female students' ease of access to tanning facilities, all NH tanning facilities (N = 261) and high schools (N = 77) in 2011 were spatially and statistically analyzed to determine schools with more facilities within 2 miles of the school and greater capacity (fewer female students per facility), for indoor tanning. Schools above the state-wide average for both measures were classified as "Easy Access" to indoor tanning. Among NH high schools, 74 % have 1 or more tanning facility within two miles and 22 % have "Easy Access" to tanning facilities. Ease of access did not differ by rurality. Lower-income school status was an independent predictor of both greater capacity and "Easy Access". While urban and rural teens have similar access to indoor tanning, female students in lower-income communities have easier access. Variations in access by community size and income must be considered in planning interventions to address youth indoor tanning.

  20. A SINE insertion causes the black-and-tan and saddle tan phenotypes in domestic dogs.

    Dreger, Dayna L; Schmutz, Sheila M

    2011-01-01

    Agouti Signaling Protein (ASIP) controls the localized expression of red and black pigment in the domestic dog through interaction with other genes, such as Melanocortin 1 Receptor and Beta-Defensin 103. Specific ASIP alleles are necessary for many of the coat color patterns, such as black-and-tan and saddle tan. Mutations in 2 ASIP alleles, a(y) and a, have previously been identified. Here, we characterize a mutation consisting of a short interspersed nuclear element (SINE) insertion in intron 1 of ASIP that allows for the differentiation of the a(w) wolf sable and a(t) black-and-tan alleles. The SINE insertion is present in dogs with the a(t) and a alleles but absent from dogs with the a(w) and a(y) alleles. Dogs with the saddle tan phenotype were all a(t)/a(t). Schnauzers were all a(w)/a(w). Genotypes of 201 dogs of 35 breeds suggest that there are only 4 ASIP alleles, as opposed to the 5 or 6 predicted in previous literature. These data demonstrate that the dominance hierarchy of ASIP is a(y) > a(w) > a(t) > a.

    Collagen represents the structural protein of the extracellular matrix, which gives strength of hides and/or skin under tanning process. Chrome tan is the most important tanning agent all over the world. The methods for production of leather evolved over several centuries as art and engineering with little understanding of the underlying science. The present work is devoted to suggest the most probable mechanistic action of chrome tan on hide proteins. First the affect of Cr upon hide protein is indicated by the studied mechanical properties. Then the spectroscopic characterization of the hide protein as well as chrome tanned leather was carried out with Horizontal Attenuated Total Reflection (HATR) FT-IR. The obtained results indicate how the chromium can attached with the active sites of collagen. Molecular modeling confirms that chromium can react with amino as well as carboxylate groups. Four schemes were obtained to describe the possible interactions of chrome tan with hide proteins.

Immediate family members' sunscreen use predicted participants' facial sunscreen use while sunbathing but not their sunscreen use on other areas of the body. In addition, familial support of a tanned appearance was inversely associated with self-tanning product use, whereas romantic partners' support of a tanned appearance was positively associated with this behavior. The results of this study suggest that it may be important to include socially significant others in interventions for reducing the risk of skin cancer in college students.

    In this issue of the Journal, Ghiasvand et al. (Am J Epidemiol. 2017;185(00):000-000) present results from a longitudinal study of the association between indoor tanning and melanoma in a large cohort of Norwegian women. These new data further support previous findings on the damaging effects of tanning bed exposure on women, particularly young women. The authors present compelling evidence that early exposure to tanning beds advances the date of diagnosis of melanoma by at least 2 years. With a strong design and a large cohort followed for a mean of 13.7 years, this study lends additional support to previous evidence of the negative effects of tanning beds and provides further justification for stronger policy initiatives designed to reduce tanning bed use among young women.

    The study of arctic or subarctic indigenous skin clothing material, known for its design and ability to keep the body warm, provides information about the tanning materials and techniques. The study also provides clues about the culture that created it, since tanning processes are often specific to certain indigenous groups. Untreated skin samples and samples treated with willow (Salix sp) bark extract and cod liver oil are compared in this study using both MRI and unilateral NMR techniques. The two types of samples show different proton spatial distributions and different relaxation times, which may also provide information about the tanning technique and aging behavior.

    2008-02-01

    We report a new method for rapid measurement of total acid number (TAN) and TAN boiling point (BP) distribution for petroleum crude and products. The technology is based on negative ion electrospray ionization mass spectrometry (ESI-MS) for selective ionization of petroleum acid and quantification of acid structures and molecular weight distributions. A chip-based nanoelectrospray system enables microscale (<200 mg) and higher throughput (20 samples/h) measurement. Naphthenic acid structures were assigned based on nominal masses of a set of predefined acid structures. Stearic acid is used as an internal standard to calibrate ESI-MS response factors for quantification purposes. With the use of structure-property correlations, boiling point distributions of TAN values can be calculated from the composition. The rapid measurement of TAN BP distributions by ESI is demonstrated for a series of high-TAN crudes and distillation cuts. TAN values determined by the technique agree well with those by the titration method. The distributed properties compare favorably with those measured by distillation and measurement of TAN of corresponding cuts.

  10. Are artificial tans the new cigarette? How plaintiffs can use the lessons of tobacco litigation in bringing claims against the indoor tanning industry.

    2008-11-01

    Indoor tanning salons have grown significantly in popularity during recent years. Scientific research has revealed a strong link between skin cancer and ultraviolet light exposure from indoor tanning lamps. Despite such dangers, federal regulations place minimal restrictions on the labeling of indoor tanning lamps. Indoor tanning salons work vigorously to dispel notions of a link to skin cancer, often falsely promoting various health benefits of indoor tanning. The first lawsuit for injuries resulting from indoor tanning was recently filed against an indoor tanning salon, and other such litigation is poised to follow. This Note examines three potential tort claims against indoor tanning manufacturers and salons, and suggests ways to formulate compelling arguments in each instance. In doing so it draws on cases finding liability in the context of cigarettes, identifying similarities between the indoor tanning and cigarette industries.

    1997-07-01

    The authors examine the prospects for determining tan {beta} from heavy Higgs scalar production in the minimal supersymmetric standard model at a future e{sup +}e{sup {minus}} collider. Their analysis is independent of assumptions of parameter unification, and they consider general radiative corrections in the Higgs sector. Bounds are presented for {radical}s = 500 GeV and 1 TeV, several Higgs masses, and a variety of integrated luminosities. For all cases considered, it is possible to distinguish low, moderate, and high tan {beta}. In addition, the authors find stringent constraints for 3 {approx_lt} tan{beta} {approx_lt} 10, and, for some scenarios, also interesting bounds on high tan {beta} through tbH{sup {+-}} production. Such measurements may provide strong tests of the Yukawa unifications in grand unified theories and make possible highly precise determinations of soft SUSY breaking mass parameters.

    2015-08-01

    Young, non-Hispanic white females represent the population most likely to use indoor tanning facilities. This population may be at increased risk of skin cancer as recent meta-analyses support a strong association between cutaneous malignancy and indoor tanning. Public perception of the purported health benefits of indoor tanning may be partially to blame for the popularity of tanning salons as a desire to prepare skin prior to sun exposure is among the most commonly cited motivations for indoor tanning. Improving education and counseling to address misconceptions regarding tanning safety will require the participation of healthcare providers for both physical and psychological screenings as well as for information dissemination. This review presents the association between tanning bed use and skin cancer, biological effects of UV radiation exposure, UV burden associated with tanning devices, public perception of tanning, demographic and psychological profile of indoor tanners, and current legislation regulating tanning bed use.

    As of August 2014, 11 states in the USA have passed under-age-18 bans on indoor tanning. The Society of Behavioral Medicine, the American Academy of Dermatology, and the American Academy of Pediatrics have all issued statements in support of an under-age-18 ban. The World Health Organization and the Food and Drug Administration have both declared indoor tanning devices as carcinogenic, and this year, the Surgeon General for the first time issued a warning on the dangers of UV radiation and indoor tanning. This essay highlights how the awareness of the risks of indoor tanning, effective policies, and a conducive political atmosphere have aligned to create a window of opportunity for further under-age-18 indoor tanning legislation. The rising number of preventable skin cancers and mortalities is an issue that transcends political party lines, and now, there is a need for support from health professionals and advocates to motivate legislators to push new under-age-18 bills past their sticking points.

    Purpose Exposure to ultraviolet radiation and a history of sunburn in childhood contribute to risk of skin cancer in adolescence and in adulthood, but many adolescents continue to seek a tan, either from the sun or from tanning beds (i.e., intentional tanning). To understand tanning behavior among adolescents, we conducted a systematic review of the literature to identify correlates of intentional tanning in the United States. Methods We included articles on original research published in English between January 1, 2001, and October 31, 2011, that used self-reported data on intentional tanning by U.S. adolescents aged 8 to 18 years and examined potential correlates of tanning behaviors. Thirteen articles met our criteria; all used cross-sectional survey data and quantitative methods to assess correlates of intentional tanning. Results Results indicate that multiple factors influence tanning among adolescents. Individual factors that correlated with intentional tanning include demographic factors (female sex, older age), attitudes (preferring tanned skin), and behaviors (participating in other risky or appearance-focused behaviors such as dieting). Social factors correlated with intentional tanning include parental influence (having a parent who tans or permits tanning) and peer influence (having friends who tan). Only four studies examined broad contextual factors such as indoor tanning laws and geographic characteristics; they found that proximity to tanning facilities and geographic characteristics (living in the Midwest or South, living in a low ultraviolet area, and attending a rural high school) are associated with intentional tanning. Conclusions These findings inform future public health research and intervention efforts to reduce intentional tanning. PMID:23601612

    Excellent weldability and good microstructural stability of 310TaN, in terms of the formation and growth of secondary phases at elevated temperature, was revealed in this investigation. The interganular stress corrosion resistance of 310TaN is superior to modified 800H and 310HCbN evaluated previously due to the fact that TaC, TaN and Ta(C,N) particles are more stable compared to Nb-rich or Ti-rich carbides, nitrides and carbonitrides presented in the other advanced alloys. Using resistance spot welding technique for which extremely fast cooling is a characteristic, it was found that a very minor amount of gain boundary liquation takes place during welding thermal cycling. The limited grain boundary liquation is of the eutectic type i.e., a low tendency to weld HAZ hot cracking.

  17. Psychosocial correlates of frequent indoor tanning among adolescent boys.

    The aim of the current study was to assess psychosocial correlates (i.e., perceived weight, weight control strategies, substance use, and victimization) of frequent indoor tanning in adolescent boys-a group at high risk for developing skin cancer. Participants (N=7,907) were drawn from a nationally representative sample of adolescent boys attending high school in the United States. Binary logistic regression revealed that extreme weight control strategies, particularly steroid use (odds ratio=3.67) and compensatory vomiting (odds ratio=2.34), along with substance use and victimization, were significantly related to frequent indoor tanning. These results highlight the role of appearance-changing, and health-risk behaviors in the context of frequent indoor tanning. Skin cancer prevention interventions may benefit from adopting approaches that integrate the treatment of body dissatisfaction and subsequent maladaptive behaviors.

  18. Effective ultraviolet irradiance measurements from artificial tanning devices in Greece.

    Artificial tanning remains very popular worldwide, despite the International Agency for Research on Cancer classification of ultraviolet (UV) radiation from sunbeds as 'carcinogenic to humans'. Greek Atomic Energy Commission has initiated a surveillance action of the artificial tanning devices in Greece in order to record the effective irradiance levels from the sunbeds and to inform and synchronise the domestic artificial tanning business sector with the requirements of the European Standard EN 60335-2-27:2010. In this direction, in situ measurements of UV emissions from sunbeds in solaria businesses all over Greece were performed from October 2013 until July 2014, with a radiometer and a portable single-monochromator spectrophotometer. Analysis of the measurements' results revealed that effective irradiance in ∼60 % of the measured sunbeds exceeded the 0.3 W m(-2) limit value set by EN 60335-2-27:2010 and only 20 % of the devices could be categorised as UV type 3.

  19. On the Classification Performance of TAN and General Bayesian Networks

    NASA Astrophysics Data System (ADS)

    Madden, Michael G.

    Over a decade ago, Friedmanet al. introduced the Tree Augmented Naïve Bayes (TAN) classifier, with experiments indicating that it significantly outperformed Naïve Bayes (NB) in terms of classification accuracy, whereas general Bayesian network (GBN) classifiers performed no better than NB. This paper challenges those claims, using a careful experimental analysis to show that GBN classifiers significantly outperform NB on datasets analyzed, and are comparable to TAN performance. It is found that the poor performance reported by Friedman et al. are not attributable to the GBN per se, but rather to their use of simple empirical frequencies to estimate GBN parameters, whereas basic parameter smoothing (used in their TAN analyses but not their GBN analyses) improves GBN performance significantly. It is concluded that, while GBN classifiers may have some limitations, they deserve greater attention, particularly in domains where insight into classification decisions, as well as good accuracy, is required.

    The development of new tanning agents and new technologies in the leather sector is required to cope with the increasingly higher environmental pressure on the current tanning materials and processes such as tanning with chromium salts. In this paper, the use of titanium wastes (cuttings) resulting from the process of obtaining highly pure titanium (ingots), for the synthesis of new tanning agent and tanning bovine hides with new tanning agent, as alternative to tanning with chromium salts are investigated. For this purpose, Ti waste and Ti-based tanning agent were characterized for metal content by inductively coupled plasma mass spectrometry (ICP-MS) and chemical analysis; the tanned leather (wet white leather) was characterized by Scanning Electron Microscope/Energy Dispersive Using X-ray (Analysis). SEM/EDX analysis for metal content; Differential scanning calorimetric (DSC), Micro-Hot-Table and standard shrinkage temperature showing a hydrothermal stability (ranged from 75.3 to 77°C) and chemical analysis showing the leather is tanned and can be processed through the subsequent mechanical operations (splitting, shaving). On the other hand, an analysis of major minor trace substances from Ti-end waste (especially vanadium content) in new tanning agent and wet white leather (not detected) and residue stream was performed and showed that leachability of vanadium is acceptable. The results obtained show that new tanning agent obtained from Ti end waste can be used for tanning bovine hides, as eco-friendly alternative for chrome tanning.

    2012-01-01

    The long-standing question of finding the momentum representation for the s-wave zero-range interaction in three spatial dimensions is here solved. This is done by expressing a certain distribution, introduced in a formal way in [S. Tan, Ann. Phys. (NY)APNYA60003-491610.1016/j.aop.2008.03.004 323, 2952 (2008)], explicitly. The resulting form of the Fourier-transformed pseudopotential remains very simple. Operator forms for the so-called Tan's selectors, which, together with Fermi-Huang pseudopotential, largely simplify the derivation of Tan's universal relations for the Fermi gas, are here derived and are also very simple. A momentum cutoff version of the pseudopotential is also provided, and with this no apparent contradiction to the notion of integrals in Tan's methods is left. The equivalence, even at the intermediate-step level, between the pseudopotential approach and momentum-space renormalization of the bare Dirac delta interaction is then shown by using the explicit form of the cutoff pseudopotential.

    Despite its known association with skin cancer, tanning remains popular among young adult women. Indoor tanning behavior has been found to be associated with affective and addictive disorders. To better understand potential psychological and biological mechanisms of tanning behavior, we investigated associations between tanning and medication (psychotropic and other) use among young women. Two hundred and fifty-three women age 18-29 years old were recruited from two northeastern university campus communities. Women self-reported tanning frequency and chronic medication use. In both univariate and multivariate analyses, indoor tanning ≥12 times last year was significantly associated with use of psychotropic medication and anti-depressants in particular. Sunbathing was not associated with medication use. Potential reasons for associations between tanning and psychotropic medication use are discussed. Indoor tanners should be warned that some psychotropic medications are photosensitizing, thus increasing risk for burns and other skin damage from indoor tanning.

    2015-02-01

    Youth use of ultraviolet-emitting indoor tanning beds represents a present and emerging public health crisis. Nearly 30% of white female high school students report tanning indoors, and a quarter of high school tanners have used a tanning bed more than 20 times in the past year. Despite the significant health risks of tanning beds, including potentially deadly melanoma and eye problems, limited actions have been taken in the U.S. to protect youth. Tobacco control policies and campaigns, which have sharply reduced youth smoking, may provide a useful framework to control indoor tanning among young people. This article describes several evidence-based tobacco control strategies with potential applicability to indoor tanning within the context of the U.S. Further, current tobacco control policies and current indoor tanning policies in the U.S. are compared, and recommendations on how to curtail youth indoor tanning are discussed.

    2015-01-01

    This paper explored how imaginary audience and personal fable ideations contribute to adolescent indoor tanning intentions directly and indirectly through the way they shape pro-tanning attitude and association with peers who use tanning beds. Five hundred and ninety-five male (n = 207) and female (n = 387) adolescents, ranging in age from 11 to 19 (M = 16.87; SD = 1.34) years completed a cross-sectional survey. Measures included imaginary audience, personal fable (three dimensions: invulnerability, uniqueness, and omnipotence), pro-tanning attitude, association with peers who use tanning beds, and tanning bed use intentions. Bootstrapping analyses documented that imaginary audience ideations are indirectly associated with indoor tanning intentions through the mediation of pro-tanning attitude and association with peers who use tanning beds. Of the personal fable ideations, only invulnerability ideation is indirectly associated with indoor tanning intentions through the mediation of association with peers who use tanning beds.

    This paper explored how imaginary audience and personal fable ideations contribute to adolescent indoor tanning intentions directly and indirectly through the way they shape pro-tanning attitude and association with peers who use tanning beds. Five hundred and ninety-five male (n = 207) and female (n = 387) adolescents, ranging in age from 11 to 19 (M = 16.87; SD = 1.34) years completed a cross-sectional survey. Measures included imaginary audience, personal fable (three dimensions: invulnerability, uniqueness, and omnipotence), pro-tanning attitude, association with peers who use tanning beds, and tanning bed use intentions. Bootstrapping analyses documented that imaginary audience ideations are indirectly associated with indoor tanning intentions through the mediation of pro-tanning attitude and association with peers who use tanning beds. Of the personal fable ideations, only invulnerability ideation is indirectly associated with indoor tanning intentions through the mediation of association with peers who use tanning beds. Design and evaluation of interventions and campaigns to reduce indoor tanning must be targeted to adolescents varying in imaginary audience ideations differently. PMID:28042281

    The mass media is an influential source of skin cancer information for the public. In 2009, the World Health Organization's International Agency for Research on Cancer classified UV radiation from tanning devices as carcinogenic. Our objective was to determine if media coverage of skin cancer and recreational tanning increased in volume or changed in nature after this classification. We conducted a directed content analysis on 29 North American popular magazines (2007-2012) to investigate the overall volume of articles on skin cancer and recreational tanning and, more specifically, the presence of skin cancer risk factors, UV behaviors, and early detection information in article text (n = 410) and images (n = 714). The volume of coverage on skin cancer and recreational tanning did not increase significantly after the 2009 classification of tanning beds as carcinogenic. Key-related messages, including that UV exposure is a risk factor for skin cancer and that indoor tanning should be avoided, were not reported more frequently after the classification, but the promotion of the tanned look as attractive was conveyed more often in images afterwards (p < .01). Content promoting high-SPF sunscreen use increased after the classification (p < .01), but there were no significant positive changes in the frequency of coverage of skin cancer risk factors, other UV behaviors, or early detection information over time. The classification of indoor tanning beds as carcinogenic had no significant impact on the volume or nature of skin cancer and recreational tanning coverage in magazines.

    The emission spectra of TaN have been investigated in the region 3000-35 000 cm -1 using a Fourier transform spectrometer. The spectra were observed in a tantalum hollow-cathode lamp by discharging a mixture of 1.5 Torr of Ne and about 6 mTorr of N 2. In addition to previously known bands, numerous additional bands were observed and assigned to a number of new transitions. The spectroscopic properties of the low-lying electronic states of TaN were also predicted by ab initio calculations. A 1Σ + state, with equilibrium constants of Be=0.457 852 1(48) cm -1, α e=0.002 235 9(67) cm -1, and Re=1.683 099 9(88) Å, has been identified as the ground state of TaN based on our experimental observations supported by the ab initio results. The first excited state has been identified as the a3Δ 1 spin component at 2827 cm -1 above the ground state. To higher energies, the states become difficult to assign because of their Hund's case (c) behavior and extensive interactions between the spin components of the electronic terms.

    Aerojet used the patented thrust augmented nozzle (TAN) concept to validate a unique means of increasing sea-level thrust in a liquid rocket booster engine. We have used knowledge gained from hypersonic Scramjet research to inject propellants into the supersonic region of the rocket engine nozzle to significantly increase sea-level thrust without significantly impacting specific impulse. The TAN concept overcomes conventional engine limitations by injecting propellants and combusting in an annular region in the divergent section of the nozzle. This injection of propellants at moderate pressures allows for obtaining high thrust at takeoff without overexpansion thrust losses. The main chamber is operated at a constant pressure while maintaining a constant head rise and flow rate of the main propellant pumps. Recent hot-fire tests have validated the design approach and thrust augmentation ratios. Calculations of nozzle performance and wall pressures were made using computational fluid dynamics analyses with and without thrust augmentation flow, resulting in good agreement between calculated and measured quantities including augmentation thrust. This paper describes the TAN concept, the test setup, test results, and calculation results.

    Youthful indoor tanning as few as ten sessions can increase the risk of melanoma by two to four times with each additional session adding another 2 % to the risk. Recent research estimates that indoor tanning can be linked to approximately 450,000 cases of skin cancer annually in the USA, Europe, and Australia. Despite these risks, indoor tanning remains popular with adolescents. This study tested the efficacy of a web-based skin cancer prevention intervention designed to reduce indoor tanning motivations in adolescent females. A nationally representative sample of 443 female teens was enrolled from an online panel into a two-arm, parallel group design, randomized controlled trial. Treatment participants received an appearance-focused intervention grounded in established health behavior change models. Controls viewed a teen alcohol prevention website. Outcome variables included willingness and intentions to indoor tan, willingness to sunless tan, and measures of indoor tanning attitudes and beliefs. The intervention decreased willingness and intentions to indoor tan and increased sunless tanning willingness relative to controls. We also examined indirect mechanisms of change through intervening variables (e.g., indoor tanning attitudes, norms, positive and negative expectancies) using the product of coefficient approach. The web-based intervention demonstrated efficacy in changing adolescent indoor tanning motivations and improving their orientation toward healthier alternatives. Results from the intervening variable analyses give guidance to future adolescent skin cancer prevention interventions.

    Unlike other health behaviors, there does not appear to be a strong relationship between perceived skin cancer risk and reduction or cessation of indoor tanning bed use. This study seeks to address this inconsistency by determining how indoor tanning bed users rationalize skin cancer risk with their tanning behavior. Qualitative textual analysis of indoor tanning message board posts (N = 330) revealed varied perceptions of risk, including acknowledging the risk of indoor tanning; denying or downplaying risk, often citing perceived health benefits associated with tanning; blaming outside forces for cancer, such as lotion or genetics; and fatalistic beliefs about cancer. These results highlight the nuanced relationship between perceived skin cancer risk and indoor tanning bed use.

    Background Appearance motives predict indoor tanning use in adolescents; however, research has primarily focused on females. Salient social factors, such as bullying victimization have yet to be explored in the context of indoor tanning. Purpose To examine the role of perceived weight and bullying victimization in indoor tanning use among adolescent males. Methods Data on perceived weight, bullying victimization, and frequency of indoor tanning were obtained from the 2009 Youth Risk Behavior Survey—a nationally representative sample of U.S. high school students. Results The association of perceived weight status with indoor tanning use significantly varied by bullying victimization, such that perceiving oneself as being very underweight or very overweight was associated with increased indoor tanning, particularly for those males who were victims of bullying. Conclusions Bullying victimization may be a risk factor for indoor tanning use among adolescent males who perceive their weight as extreme. PMID:23494291

    2006-05-01

    This study investigated cognitive predictors of tanning salon use, based on Jaccard's Theory of Alternative Behavior. A total of 164 undergraduates completed questionnaires that assessed tanning salon use, attitudes toward tanning salon use and attitudes toward behavioral alternatives for enhancing appearance, relaxing and socializing. Results indicated that attitudes toward alternatives for enhancing appearance were not significantly related to tanning salon use. However, favorable attitudes toward engaging in a hobby to relax and going to the gym to socialize were inversely related to frequency of tanning salon use. Findings suggest that interventions for reducing skin cancer risk should focus not only on decreasing favorable attitudes toward tanning, but also on increasing favorable attitudes toward healthier alternatives to tanning salon use.

    The present report shows a partial biochemical characterization and life cycle expression of N-β-alanyldopamine hydrolase (Tan protein) in Ceratitis capitata and Drosophila melanogaster. This enzyme catalyzes the hydrolysis of N-β-alanyldopamine (NBAD), the main tanning precursor of insect brown cuticles. It also plays an important role in the metabolism of brain neurotransmitters, recycling dopamine and histamine. In contrast to NBAD-synthase, Tan is expressed constitutively in epidermis and does not respond directly to microbial challenge. Immunodetection experiments showed the novel localization of NBAD-hydrolase in the embryo central neural system and in different regions of the adult brain, in addition to optic lobes. We sequenced and characterized Drosophila mutants tan¹ and tan³. The latter appears to be a mutant with normal expression in neural tissue but weak one in epidermis.

    Background Younger indoor tanning initiation leads to greater melanoma risk due to more frequent and persistent behavior. Despite this, there are no published studies exploring the predictors of indoor tanning initiation in teen populations. Purpose This longitudinal study uses latent profile analysis to examine indoor tanning initiation in indoor tanning risk subgroups from a national sample of female adolescents. Methods Latent profile analysis used indoor tanning beliefs and perceptions to identify indoor tanning initiation risk subgroups. The teens in each subgroup were reassessed on indoor tanning initiation after a year. Results Three subgroups were identified: a low-risk, Anti-Tanning subgroup (18.6%) characterized by low scores on positive indoor tanning belief scales and high scores on beliefs about indoor tanning dangers; a moderate-risk Aware Social Tanner subgroup (47.2%) characterized by high scores on positive indoor tanning belief scales but also high scores on beliefs about indoor tanning dangers; and a high-risk Risky Relaxation Tanner subgroup (34.2%) characterized by high scores on positive indoor tanning belief scales and low scores on beliefs about indoor tanning dangers. Teens in the Aware Social Tanner and Risky Relaxation Tanner subgroups were significantly more likely to initiate indoor tanning in the following year. Conclusions These findings highlight the need to identify teens at risk for indoor tanning initiation and develop tailored interventions that will move them to the lowest risk subgroup. Subgroup correlates suggest parent and peer-based interventions may be successful. PMID:26370893

    Few surveillance tools exist for monitoring tanning bed injuries. Twitter data were examined to identify and describe reports of tanning bed-caused burns. Tweets sent in 2013 containing keywords for tanning bed use and burning were content analyzed to determine whether a burn caused by a tanning bed was described, and additional data on tanning behavior and burn characteristics were extracted. After content assessment, 15,178 (64 %) tweets were found to describe a tanning bed-caused burn. Sites most reportedly burnt were buttocks (n = 3117), face/head (n = 1020), and chest/breast (n = 546). Alarmingly, 200 burns to the eyes/eyelids were mentioned. A total of 456 tweets described burning >1 time from a tanning bed. A total of 211 tweets mentioned falling asleep inside the tanning bed. In 2013, over 15,000 tweets reported tanning bed-caused burns. Twitter data provides unique insight into tanning behaviors and injuries not captured through traditional public health surveillance.

    Abstract Introduction: Although indoor tanning causes cancer, it remains relatively common among adolescents. Little is known about indoor tanning prevalence and habits in Canada, and even less about associated behaviours. This study explores the prevalence of adolescent indoor tanning in Manitoba and its association with other demographic characteristics and health behaviours. Methods: We conducted secondary analyses of the 2012/13 Manitoba Youth Health Survey data collected from Grade 7 to 12 students (n = 64 174) and examined associations between indoor tanning (whether participants had ever used artificial tanning equipment) and 25 variables. Variables with statistically significant associations to indoor tanning were tested for collinearity and grouped based on strong associations. For each group of highly associated variables, the variable with the greatest effect upon indoor tanning was placed into the final logistic regression model. Separate analyses were conducted for males and females to better understand sex-based differences, and analyses were adjusted for age. Results: Overall, 4% of male and 9% of female students reported indoor tanning, and prevalence increased with age. Relationships between indoor tanning and other variables were similar for male and female students. Binary logistic regression models indicated that several variables significantly predicted indoor tanning, including having part-time work, being physically active, engaging in various risk behaviours such as driving after drinking for males and unplanned sex after alcohol/drugs for females, experiencing someone say something bad about one’s body shape/size/appearance, identifying as trans or with another gender, consuming creatine/other supplements and, for females only, never/rarely using sun protection. Conclusion: Indoor tanning among adolescents was associated with age, part-time work, physical activity and many consumption behaviours and lifestyle risk factors. Though

    Background Unlike other types of cancer, skin cancer incidence rates are on the rise and adolescent females are particularly likely to tan indoors, a major risk factor. However, little research has examined the role of media use in encouraging or discouraging this dangerous behavior in this population. Aims To empirically assess the links between media use, indoor tanning-related outcome expectations, and behavioral intentions. Method A survey of adolescent females (N = 510) ages 15 to 18 in the Southeastern United States assessed demographics, types of media use, and indoor tanning intentions. Results Significant correlations between media use and indoor tanning outcome expectations were found. Use of interpersonal and social media (i.e., talking on the phone, texting, and online social media) were positively associated with positive outcome expectations about indoor tanning and negatively associated with negative outcome expectations. A path analysis revealed that interpersonal/social media use had indirect associations with indoor tanning intentions via tanning outcome expectations. Mass media use (e.g., news media, entertainment media, and magazines) was not significantly associated with most indoor tanning outcome expectations but did have a direct negative association with behavioral intentions. Discussion There are important relationships between media use, indoor tanning outcome expectations, and behavioral intentions. Interpersonal and social media use may help cultivate outcome expectations that encourage indoor tanning, which in turn may increase intentions to tan, while news media consumption in particular may reduce intentions to tan. Conclusion These findings highlight the social nature of adolescent females and point to specific intervention channels for reducing indoor tanning among this population.

    Indoor tanning is common in spite of its classification as carcinogenic. Too high an ultraviolet (UV) irradiance and a lack of compliance with regulations have been reported. We measured UV irradiance from a large number of Norwegian solariums (sunbeds and stand-up cabinets) currently in use. Compliance (solariums and facilities) with national regulations and the effect of inspections delegated to local authorities (since 2004) were also studied. In 2008, 78 tanning facilities were selected from six regions throughout Norway that contained municipalities with and without local inspections. UV irradiance was measured with a CCD spectroradiometer in 194 out of 410 inspected solariums. Mean erythema weighted short (280-320 nm) and long (320-400 nm) wave UV irradiances were 0.194 (95% confidence interval (CI) 0.184-0.205) and 0.156 (95% CI 0.148-0.164) W m(-2), respectively. Only 23% of the solariums were below the UV type 3 limit (<0.15 W m(-2), short and long wave). Irradiances varied between solariums: spectral UVB (280-315 nm) and UVA (315-400 nm) irradiances were 0.5-3.7 and 3-26 times, respectively, higher than from Oslo summer sun. In total, 89.9% of the tanning facilities were unattended. Overall compliance increased since the first study in 1998-1999, but total UV irradiance did not decrease, mainly because of higher UVA irradiance in 2008. Solariums have become even less similar to natural sun due to higher UVA irradiance. Local inspections gave better compliance with regulations, but irradiances were significantly higher in municipalities with inspections (p ≤ 0.001, compared to without). Unpredictable UV irradiance combined with insufficient customer guidance may give a high risk of negative health effects from solarium use.

    This paper describes the development and implementation of an integrated resistor process based on reactively sputtered tantalum nitride. Image reversal lithography was shown to be a superior method for liftoff patterning of these films. The results of a response surface DOE for the sputter deposition of the films are discussed. Several approaches to stabilization baking were examined and the advantages of the hot plate method are shown. In support of a new capability to produce special-purpose HBT-based Small-Scale Integrated Circuits (SSICs), we developed our existing TaN resistor process, designed for research prototyping, into one with greater maturity and robustness. Included in this work was the migration of our TaN deposition process from a research-oriented tool to a tool more suitable for production. Also included was implementation and optimization of a liftoff process for the sputtered TaN to avoid the complicating effects of subtractive etching over potentially sensitive surfaces. Finally, the method and conditions for stabilization baking of the resistors was experimentally determined to complete the full implementation of the resistor module. Much of the work to be described involves the migration between sputter deposition tools - from a Kurt J. Lesker CMS-18 to a Denton Discovery 550. Though they use nominally the same deposition technique (reactive sputtering of Ta with N{sup +} in a RF-excited Ar plasma), they differ substantially in their design and produce clearly different results in terms of resistivity, conformity of the film and the difference between as-deposited and stabilized films. We will describe the design of and results from the design of experiments (DOE)-based method of process optimization on the new tool and compare this to what had been used on the old tool.

    A novel approach, based on chitosan heavy-metal sequestrating ability, is proposed for chromium(III) removal from spent tanning liquor. Experimental results, obtained at lab-scale using real wastewater, are presented and discussed. Resulting efficiencies are extremely high, and strongly dependent on chitosan dose and pH value. Comparative analyses with other polysaccharides is also carried out showing that amine groups are more efficient than carboxyl and sulphate ones. Chromium recovery from sorption complexes and chitosan regeneration is finally proposed to optimize the whole process.

    Tantalum nitride, TaN, has been recently identified as a leading candidate for extending the study of T, P-odd effects in the nuclear realm to include proton, neutron, and quark electric dipole moments (EDM) and beyond. This is primarily due to enhancements in the interaction of electrons with the nuclear magnetic quadrupole moment (MQM) and the resulting parity-violating effects. Study of the dispersed laser induced fluorescence resulting from the excitation of the 17570.80 (Ω = 0+) , 18427.38 (Ω = 0+) , 19216.80 (Ω = 1), and 19396.78 (Ω = 1) bands above the X1Σ+ (v = 0) ground state of TaN near 569 nm, 543 nm, 520 nm, and 515 nm has enabled a determination of the branching ratios and transition dipole moments of all 4 states. Radiative lifetimes of 454(32) ns, 479(12) ns, 333(4) ns, and 480(17) ns respectively were measured from an analysis of the fluorescence decay curves, and potential optical pumping approaches for both populating and detecting the parity-violation sensitive 3Δ1 state are proposed. Further experiments using CW laser excitation have enabled the observation of the hyperfine structure of several bands in the gateway 18427.38 (Ω = 0+) to X1Σ+ (v = 0) transition, and analysis of these complex spectra is underway.

    Monocyclic and bicyclic oxazolidines were offered at three different junctures of chrome tanning process viz. prior to BCS offer, along with BCS and after basification. It was found that oxazolidine when offered after basification brought about better chromium uptake and reduction of chromium load in the wastewater. Offer of oxazolidine was also varied. Increase in offer of oxazolidine from 0.25% to 1% was found to enhance the chromium uptake and decrease the chromium load in wastewater. But the increase in uptake was not proportionate to the increase in oxazolidine offer more than 0.75%. Offer of 1% Zoldine ZA 78 (monocyclic oxazolidine) and Zoldine ZE (bicyclic oxazolidine) after basification brought about 63.4% and 73.1% enhancement in chrome content in leather compared to control where oxazolidine was not offered. The tone of the wetblue was found to be altered moderately. However this did not call for any process adjustments in wet-finishing. The oxazolidine treated leathers were found to be immensely fuller and tighter. It was found experimentally that offer of 1% of oxazolidine facilitated reduction in the offer of syntans administered for filling and grain tightening by around 46%. Oxazolidine could bring about significant reduction in cost of chemicals apart from resulting environmental benefits due to enhancement of chromium uptake during tanning.

    Objective This manuscript describes the acceptability and preliminary behavioral outcomes from a pilot randomized control trial of a web-based indoor tanning intervention for young adult women. The intervention targets indoor tanning user’s perceptions of then benefits and value of tanning and addresses the role of body image-related constructs in indoor tanning. Methods Participants were 186 young adult women who reported indoor tanning at least once in the past 12 months. The study design was a 2-arm randomized controlled trial with pre and post assessments and random assignment to an intervention or control condition. Intervention acceptability was assessed by obtaining participants’ evaluation of the intervention. Regression analyses were used to test for intervention condition differences in preliminary behavioral outcomes measured at 6-weeks post-intervention. Results Participants provided favorable evaluations of the intervention on several dimensions and a highly positive overall rating. Intervention participants were more likely to report abstaining from indoor tanning and indicated a lower likelihood of using indoor tanning in the future compared to control participants on the post-intervention assessment. No differences were found for sunburns. Conclusions The results of this pilot randomized controlled trial provide evidence that the indoor tanning intervention is acceptable to participants and may encourage cessation of indoor tanning behavior. The findings provide preliminary support for an indoor tanning intervention that engages tanners to challenge their beliefs about the benefits of indoor tanning. The use of a web-based indoor tanning intervention is unique and provides strong potential for dissemination. PMID:26651469

    Indoor tanning (IT) has been linked with psychiatric and addictive symptoms, and frequent tanning may indicate tanning dependence (addiction). The current study evaluated the effects of an IT episode on mood states and the association of these effects with psychiatric and addictive symptoms among young adult female indoor tanners. One-hundred thirty-nine female university students aged 18-25 years who had indoor tanned completed an online survey including the Positive and Negative Affects Scales and a standardized psychiatric interview (the MINI International Neuropsychiatric Interview) via telephone. Psychiatric and addictive symptoms were relatively common among these young adult female indoor tanners. Overall, participants reported significant decreases in both negative (upset, scared, irritable, nervous, jittery, afraid) and positive (feeling interested) mood states after their most recent tanning episode. Multivariable linear regression analyses showed that more frequent indoor tanning in the past month and symptoms of illicit drug use disorders were associated with decreases in negative mood, and symptoms of generalized anxiety disorder were associated with a decrease in feeling interested. In summary, indoor tanners report relatively high rates of psychiatric and substance use symptoms, including symptoms of tanning dependence, and indoor tanning appears to alter mood. Women with certain substance use and psychiatric characteristics may be more vulnerable to such mood changes after tanning indoors. Further research is needed to clarify the relationships among these variables.

    Tanned hides, a common form of preservation of mammalian specimens, are usually resistant to DNA analysis. However, we show that DNA isolated from the pulp of claws of tanned hides amplifies well for microsatellite markers. For eight wolverine and eight lynx hides tanned 5-20 years ago, 93-98% of replicate amplifications gave distinct PCR products. Genotypes obtained in analysis of tissue samples of the same individuals were in all cases in agreement with those obtained by analysis of claws. We thus conclude that the use of claws from tanned hides offers new possibilities to genetic studies of preserved mammalian specimens, for instance, in the monitoring of illegal trade.

    Although personal melanoma risk factors are well established, the contribution of socioeconomic factors, including clothing styles, social norms, medical paradigms, perceptions of tanned skin, economic trends, and travel patterns, to melanoma incidence has not been fully explored. We analyzed artwork, advertisements, fashion trends, and data regarding leisure-time activities to estimate historical changes in UV skin exposure. We used data from national cancer registries to compare melanoma incidence rates with estimated skin exposure and found that they rose in parallel. Although firm conclusions about melanoma causation cannot be made in an analysis such as this, we provide a cross-disciplinary, historical framework in which to consider public health and educational measures that may ultimately help reverse melanoma incidence trends.

    The mortality of 2926 male workers at the tanneries in the "leather area" of Tuscany was examined from 1950 to 1983 comparing it with the national mortality. Cancer mortality was of particular concern because of the many chemicals known to be definite or suspected carcinogens used in the tanning cycle, in particular chromate pigments, benzidine based dyes, formaldehyde, and organic solvents. There was no excess of deaths for cancers of all sites but slight increases in deaths from cancer of the lung (SMR = 131, CI 95% = 88-182), bladder (SMR = 150, CI 95% = 48-349), kidney (SMR = 323, CI 95% = 86-827), pancreas (SMR = 146, CI 95% = 39-373), and leukaemias (SMR = 164, CI 95% = 53-382) occurred. Two cases of soft tissue sarcomas were observed versus 0.09 expected (SMR = 2178, CI 95% = 250-8023). PMID:2818971

    Melanoma is the most common cancer among 15- to 29-year-olds in Australia, with rates increasing with age. The 'Dark Side of Tanning' (DSOT) mass media campaign was developed in 2007 to influence attitudes related to tanning. This study aimed to assess recall and impact of the DSOT campaign. Data were collected using online surveys of 13- to 44-year-olds living in New South Wales in the summer months of 2007-2010 (n = 7490). Regression models were used to determine predictors of recall of DSOT and to investigate associations between exposure to the campaign and tanning attitudes. The campaign achieved consistently high recall (unprompted recall 42-53% during campaign periods; prompted recall 76-84%). Those who recalled DSOT advertisements had a higher likelihood of reporting negative tanning attitudes compared with those who reported no recall, after adjusting for other factors (odds ratio [OR] 1.13, 95% confidence interval [CI] 1.01-1.27 for unprompted recall; OR 1.19, 95% CI 1.03-1.36 for prompted recall). Being interviewed in later campaign years was also a significant predictor of negative tanning attitudes (e.g. fourth year of campaign versus first year: OR 1.24, 95% CI 1.01-1.53). These results suggest that mass media campaigns have potential to influence tanning-related attitudes and could play an important role in skin cancer prevention.

    Natural and artificial tanning have become very popular in Western culture, yet at the same time, there is still a psychodermatology concern for this activity. Not much has been examined with the psychological aspects of tanning and sunscreen use. The purpose of this study is to examine the psychosocial effects associated with sun protection, natural, and artificial tanning among individuals 18 years old or older visiting the University of Miami Dermatology Outpatient Clinic. We distributed a survey on tanning and sunscreen use to 150 dermatology outpatients, hospital employees, and hospital visitors for three weeks during June/July 2015 asking about how often they tan, use sunscreen, and how they feel about this topic. Demographics, such as gender, ethnicity, and education were taken into consideration to examine the different responses in each category. Our results suggest that people's perception to tanning and sunscreen use have evolved over time. Most people in South Florida nowadays feel guilty when exposed to natural sunlight without sunscreen and do not tan frequently. The majority of the people, specifically women, utilize the recommended amount of sunscreen with a sun protection factor of 30-50. However, we can conclude that communication between social media and the general public can affect people's decision-making on tanning and sunscreen use with physician advice being the most effective method of encouraging people to use sunscreen. This study will add to the growing knowledge about psychodermatology.

    Indoor tanning is carcinogenic to humans. Individuals report that they tan indoors before planning to be in the sun to prevent sunburns, but whether skin cancer is subsequently reduced is unknown. Using a population-based case-control study, we calculated the association between melanoma and indoor tanning after excluding exposed participants reporting indoor tanning-related burns, stratified by their number of lifetime sunburns (0, 1-2, 3-5, >5). Confounding was addressed using propensity score analysis methods. All statistical tests were two-sided. We observed increased risk of melanoma across all sunburn categories for participants who had tanned indoors without burning compared with those who never tanned indoors, including those who reported zero lifetime sunburns (odds ratio = 3.87; 95% confidence interval = 1.68 to 8.91; P = .002). These data provide evidence that indoor tanning is a risk factor for melanoma even among persons who reported never experiencing burns from indoor tanning or outdoor sun exposure.

    Many people frequently tan indoors despite being aware of the increased risk of melanoma. Ultraviolet radiation is hypothesized to modify biological reward pathways, for example, through the dopamine neurotransmitter system, to reinforce tanning behaviour. In this pilot study, we relied on questionnaire and DNA data from a recently completed case-control study to examine 67 single-nucleotide polymorphisms (SNPs) and related haplotypes in five dopamine receptor and drug metabolism genes in relation to indoor tanning among controls. We also examined the association between individual SNPS and likelihood of melanoma, adjusting for or stratifying on indoor tanning status. In candidate and haplotype gene analyses, variants only in the DRD2 dopamine receptor and ANKK1 signalling genes were positively associated with indoor tanning use among controls; only associations for ANKK1 remained statistically significant (P < 0.05) after adjustment. Several SNPs in ANKK1 and DRD2 associated with indoor tanning among controls were also found to be associated with increased risk of melanoma. Upon stratifying for indoor tanning status, one ANKK1 SNP was positively associated with melanoma among non-tanners, while three DRD2 SNPS were positively associated with melanoma among tanners or non-tanners, depending on the SNP. These alleles represent important genomic regions to further explore addictive tanning behaviour.

    Australia has a significant proportion of residents of Asian heritage. Although the incidence of skin cancer is lower in those of Asian heritage than Caucasians, their prognosis is often worse. Sociocultural variables are central to the tanning behaviours of individuals from Western cultures. We examined the role of sociocultural variables in the tanning behaviours (outdoor tanning, indoor/solarium and fake tan use) among Asian Australians. A sample of 399 young adults identifying either as a person of Asian heritage or as Asian Australian participated in an online survey. Our results suggest that Asian Australians are at risk of skin cancer; over 35 % of the sample reported engaging in outdoor tanning and over 10 % in solarium tanning. After controlling for demographic factors and skin cancer knowledge, preferring a darker skin tone and being acculturated to Australia were significantly associated with tanning behaviour. Participants' low levels of skin cancer knowledge are of concern, and possibilities for improving knowledge levels in this group are considered. Further, we recommended that future research studies investigate sociocultural and appearance-related beliefs associated with tanning behaviours in this population, in order to determine best avenues for intervention.

    In all tanning technology operations wastes are generated. These reach the environment as residual waters, solid and liquid waste as well as atmospheric emissions and odours. This study tests an alternative method to the traditional tanning method at an industrial level. The new method is based on tanning without float and by significantly increasing the temperature at the end of the tanning process. The properties of the leathers obtained using the two methods have been compared and the results indicate that those leathers have similar physical, chemical, and organoleptic properties. However, the differences existing from the environmental point of view are significant. It is not necessary to use clean water for this tanning. Moreover, there is a 75% reduction of the residual float, a 91% reduction of the chrome discharged, and a 94% reduction of the chlorides discharged. A financial assessment was carried out to demonstrate that the newly proposed system is 32% more economic than the traditional one.

    Historical reviews suggest that tanning first became fashionable in the 1920s or 1930s. To quantitatively and qualitatively examine changes in tanning attitudes portrayed in the popular women's press during the early 20th century, we reviewed summer issues of Vogue and Harper's Bazaar for the years 1920, 1927, 1928, and 1929. We examined these issues for articles and advertisements promoting skin tanning or skin bleaching and protection. We found that articles and advertisements promoting the fashionable aspects of tanned skin were more numerous in 1928 and 1929 than in 1927 and 1920, whereas those promoting pale skin (by bleaching or protection) were less numerous. These findings demonstrate a clear shift in attitudes toward tanned skin during this period. PMID:19846688

    Sunless tanning formulas have become increasingly popular in recent years for their ability to give people convincing tans without the dangers of skin cancer. Most sunless tanners currently on the market contain dihydroxyacetone (DHA), a keto sugar with three carbons. The temporary pigment provided by these formulas is designed to resemble a UV-induced tan. This study evaluated the effectiveness of carbomer gels and cold process self emulsifying bases on skin pigmentation, using different concentrations of a chemical system composed of DHA and N-acetyl tyrosine, which are found in moulted snake skins and their effectiveness was tested by Mexameter(®) MX 18. Eight different sunless tanning formulas were developed, four of which were gels and four of which were emulsions (base, base plus 4.0%, 5.0% and 6.0% (w/w) of a system of DHA and N-acetyl tyrosine). Tests to determine the extent of artificial tanning were done by applying 30 mg cm(-2) of each formula onto standard sizes of moulted snake skin (2.0 cm × 3.0 cm). A Mexameter(®) MX 18 was used to evaluate the extent of coloration in the moulted snake skin at T(0) (before the application) and after 24, 48, 72, 168, 192 and 216 h. The moulted snake skins can be used as an alternative membrane model for in vitro sunless tanning efficacy tests due to their similarity to the human stratum corneum. The DHA concentration was found to influence the initiation of the pigmentation in both sunless tanning systems (emulsion and gel) as well as the time required to increases by a given amount on the tanning index. In the emulsion system, the DHA concentration also influenced the final value on the tanning index. The type of system (emulsion or gel) has no influence on the final value in the tanning index after 216 h for samples with the same DHA concentration.

    There is emerging evidence for the relationship between indoor tanning and melanoma. Eighty-five indoor tanning facilities in New York City were observed to determine number of tanning machines, pricing, promotions, products, and hours. Census data by zip code was used to determine population density, gender, race, age, percent living in poverty, percent unemployed, and percent college educated of areas in which tanning facilities were located. Pricing varied by the type of machine, number of sessions purchased, and single versus bundled sessions. Facilities were located in areas that had greater population density and slightly greater median age. Compared with the zip code areas with no facilities, those with tanning facilities had a higher proportion of white residents; a lower proportion of residents living in poverty and unemployed; and a higher proportion of residents with a college education. Our data suggest that the strategic location of facilities and promotions used in NYC seek to maximize patronage by those with comparatively high levels of income and education and who may be more influenced by the social desirability of artificial tanning. Long-term interventions aimed at changing social norms regarding tan skin are needed.

    Concerns on environmental waste problem caused by chrome tanned leather wastes in huge amount have caused an increasing interest in developing this wastes in many composite formation. This leather dust was used as filler in acrylonitrile butadiene rubber (NBR) before treatment and after treatment with ammonia solution and sod. formate. Different formulations of NBR/ leather dust (untreated-treated with ammonia solution—treated with sod. formate) composites are prepared. The formed composite exhibit a considerable improvement in some of their properties such as rheometric characteristics especially with composites loaded with treated leather dust. Tensile strength, modulus at 100% elongation, hardness and youngs modulus were improved then by further loading start to be steady or decrease. Cross linking density in toluene were increased by incorporation of leather dust treated or untreated resulting in decreases in equilibrium swelling. Distinct increase in the ageing coefficient of both treated and untreated leather with drop in NBR vulcanizates without leather dust. Addition of leather dust treated or untreated exhibit better thermal stability.

Some researchers have interpreted habitual use of quadrupedalism by these individuals from an evolutionary perspective, suggesting that it represents an atavistic expression of our quadrupedal primate ancestry or “devolution.” In support of this idea, individuals with “UTS” are said to use diagonal sequence quadrupedalism, a type of quadrupedal gait that distinguishes primates from most other mammals. Although the use of primate-like quadrupedal gait in humans would not be sufficient to support the conclusion of evolutionary “reversal,” no quantitative gait analyses were presented to support this claim. Using standard gait analysis of 518 quadrupedal strides from video sequences of individuals with “UTS”, we found that these humans almost exclusively used lateral sequence–not diagonal sequence–quadrupedal gaits. The quadrupedal gait of these individuals has therefore been erroneously described as primate-like, further weakening the “devolution” hypothesis. In fact, the quadrupedalism exhibited by individuals with UTS resembles that of healthy adult humans asked to walk quadrupedally in an experimental setting. We conclude that quadrupedalism in healthy adults or those with a physical disability can be explained using biomechanical principles rather than evolutionary assumptions. PMID:25029457

    Background Indoor tanning elevates the risk for melanoma, which is now the most common cancer in US women aged 25-29. Public policies restricting access to indoor tanning by minors to reduce melanoma morbidity and mortality in teens are emerging. In the United States, the most common policy restricting indoor tanning in minors involves parents providing either written or in person consent for the minor to purchase a tanning visit. The effectiveness of this policy relies on parents being properly educated about the harms of indoor tanning to their children. Objective This randomized controlled trial will test the efficacy of a Facebook-delivered health communication intervention targeting mothers of teenage girls. The intervention will use health communication and behavioral modification strategies to reduce mothers’ permissiveness regarding their teenage daughters’ use of indoor tanning relative to an attention-control condition with the ultimate goal of reducing indoor tanning in both daughters and mothers. Methods The study is a 12-month randomized controlled trial comparing 2 conditions: an attention control Facebook private group where content will be relevant to teen health with 25% focused on prescription drug abuse, a topic unrelated to tanning; and the intervention condition will enter participants into a Facebook private group where 25% of the teen health content will be focused on indoor tanning. A cohort of 2000 mother-teen daughter dyads will be recruited to participate in this study. Only mothers will participate in the Facebook groups. Both mothers and daughters will complete measures at baseline, end of intervention (1-year) and 6 months post-intervention. Primary outcomes include mothers’ permissiveness regarding their teenage daughters’ use of indoor tanning, teenage daughters’ perception of their mothers’ permissiveness, and indoor tanning by both mothers and daughters. Results The first dyad was enrolled on March 31, 2016, and we

  15. Evaluation of DEM generation based on Interferometric SAR using TanDEM-X data in Tokyo

    Avtar, Ram; Yunus, Ali P.; Kraines, Steven; Yamamuro, Masumi

    This study is focused on the evaluation of a Digital Elevation Model (DEM) for Tokyo, Japan from data collected by the recently launched TerraSAR add-on for Digital Elevation Measurements (TanDEM-X), satellite of the German Aerospace Center (DLR). The aim of the TanDEM-X mission is to use Interferometric SAR techniques to generate a consistent high resolution global DEM dataset. In order to generate an accurate global DEM using TanDEM-X data, it is important to evaluate the accuracy at different sites around the world. Here, we report our efforts to generate a high-resolution DEM of the Tokyo metropolitan region using TanDEM-X data. We also compare the TanDEM-X DEM with other existing DEMs for the Tokyo region. Statistical techniques were used to calculate the elevation differences between the TanDEM-X DEM and the reference data. Two high-resolution LiDAR DEMs are used as independent reference data. The vertical accuracy of the TanDEM-X DEM evaluated using the Root Mean Square Error (RMSE) is considerably higher than the existing global digital elevation models. However, the local area DEM generated by Geospatial Information Authority of Japan (GSI DEM) showed the highest accuracy among all non-LiDAR DEM's. The vertical accuracy in terms of RMSE estimated using the 2 m LiDAR as reference is 3.20 m for TanDEM-X, 2.44 m for the GSI, 7.00 m for SRTM DEM and 10.24 m for ASTER-GDEM. We also compared the accuracy of TanDEM-X with the other DEMs for different types of land cover classes. The results show that the absolute elevation error of TanDEM-X is higher for urban and vegetated areas, likewise to those observed for other global DEM's. This is probably because the radar signals used by TanDEM-X tend to measure the first reflective surface that is encountered, which is often the top of the buildings or canopy. Hence, the TanDEM-X based DEM is more akin to a Digital Surface Model (DSM).

  17. Twenty questions for tanning facility operators: a survey of operator knowledge.

    PubMed

    Ross, R N; Phillips, B

    1994-01-01

    A two-page questionnaire was administered to 37 tanning operators in five municipalities in BC's lower mainland. The results were analyzed to determine the knowledge base of the participants as it related to ultraviolet radiation (UVR), tanning equipment, biological effects of exposure and the advice given to clients. Only 19% of the participants scored high enough to meet Alberta's criteria for adequate knowledge to operate a tanning facility. Participants seemed knowledgeable about skin type, premature skin aging effects, skin cancer, cataracts and skin and eye irritation. The greatest knowledge deficiencies identified were 1) the definition of UVA and UVB; 2) the biological role of UVA and UVB as it relates to tanning; 3) the degree to which UVA and UVB is emitted by sunbeds; and 4) knowledge of common drugs and medications that cause photosensitivity. Follow-up activity is briefly described.

  5. DNA damage and radiosensitizers: M. luteus sensitive sites for misonidazole-TAN combination

    1982-10-01

    It has been shown previously that TAN does not enhance production of single-strand breaks (SSB) in DNA of Chinese hamster cells irradiated under hypoxia. In contrast, misonidazole does enhance the yield of SSB, but this SSB enhancement by misonidazole is reduced if TAN is present with misonidazole during irradiation. It was also shown that each of these sensitizers enhances base/sugar damage, measured with the aid of bacterial enzymes (MLS). The results presented here for MLS damage in mammalian cells irradiated in the presence of the misonidazole-TAN combination indicate that the two drugs act independently in enhancing MLS damage, and hence they interact with different types of lesions to produce base/sugar damage. It is proposed that the protection by TAN in mammalian cells observed at the survival level is due to repair of some of that type of damage which would otherwise become a misonidazole-enhanced SSB.

  17. SEMICONDUCTOR TECHNOLOGY: TaN wet etch for application in dual-metal-gate integration technology

    Yongliang, Li; Qiuxia, Xu

    2009-12-01

    Wet-etch etchants and the TaN film method for dual-metal-gate integration are investigated. Both HF/HN O3/H2O and NH4OH/H2O2 solutions can etch TaN effectively, but poor selectivity to the gate dielectric for the HF/HNO3/H2O solution due to HF being included in HF/HNO3/H2O, and the fact that TaN is difficult to etch in the NH4OH/H2O2 solution at the first stage due to the thin TaOxNy layer on the TaN surface, mean that they are difficult to individually apply to dual-metal-gate integration. A two-step wet etching strategy using the HF/HNO3/H2O solution first and the NH4OH/H2O2 solution later can fully remove thin TaN film with a photo-resist mask and has high selectivity to the HfSiON dielectric film underneath. High-k dielectric film surfaces are smooth after wet etching of the TaN metal gate and MOSCAPs show well-behaved C-V and Jg-Vg characteristics, which all prove that the wet etching of TaN has little impact on electrical performance and can be applied to dual-metal-gate integration technology for removing the first TaN metal gate in the PMOS region.

    Exposure to ultraviolet radiation from indoor tanning device use is associated with an increased risk of skin cancer, including risk of malignant melanoma, and is an urgent public health problem. By reducing indoor tanning, future cases of skin cancer could be prevented, along with the associated morbidity, mortality, and healthcare costs. On August 20, 2012, the CDC hosted a meeting to discuss the current body of evidence on strategies to reduce indoor tanning as well as research gaps. Using the Action Model to Achieve Healthy People 2020 Overarching Goals as a framework, the current paper provides highlights on the topics that were discussed, including (1) the state of the evidence on strategies to reduce indoor tanning; (2) the tools necessary to effectively assess, monitor, and evaluate the short- and long-term impact of interventions designed to reduce indoor tanning; and (3) strategies to align efforts at the national, state, and local levels through transdisciplinary collaboration and coordination across multiple sectors. Although many challenges and barriers exist, a coordinated, multilevel, transdisciplinary approach has the potential to reduce indoor tanning and prevent future cases of skin cancer.

    Given the prevalence and risk associated with indoor tanning among college students, university campuses constitute a prime target for skin cancer prevention. This report identifies the successes and challenges faced in promoting a campus-wide tan-free policy through the National Council on Skin Cancer Prevention (NCSCP) Indoor Tan-Free Skin Smart Campus Initiative. Beginning in February 2016, we communicated with university faculty or staff members who have participated in skin cancer prevention via education, clinical care, or research at 20 universities regarding the steps to adopt the tan-free policy. One campus, East Tennessee State University (ETSU), successfully fulfilled all criteria and implemented the policy change to become the first US Indoor Tan-Free Skin Smart Campus. The greatest challenge faced in recruiting campuses was gaining administrative support. Reported reasons for not adopting the policy change included wanting to wait for other schools to join first and not seeing it as a top priority. Despite the importance of improving skin cancer awareness and decreasing tanning among university students, we faced several challenges in promoting campus-wide policy change. We identify a need for research on effective ways to disseminate university health policies and increased involvement of healthcare providers in policy-related work.

  2. Comparison of advertising strategies between the indoor tanning and tobacco industries.

    2010-04-01

    The indoor tanning industry is large and continues to grow, with 2007 domestic sales in excess of $5 billion. Advertising is central to shaping the consumer's perception of indoor tanning as well as driving industry demand. This article aims to identify key drivers of consumer appeal by comparing tanning advertising strategies to those used by tobacco marketers. Tobacco advertising was selected as a reference framework because it is both well documented and designed to promote a product with known health hazards. Two thousand advertisements from 4 large tobacco advertisement databases were analyzed for type of advertisement strategy used, and 4 advertising method categories were devised to incorporate the maximum number of advertisements reviewed. Subsequently, contemporary tanning advertisements were collected from industry magazines and salon websites and evaluated relative to the identified strategy profiles. Both industries have relied on similar advertising strategies, including mitigating health concerns, appealing to a sense of social acceptance, emphasizing psychotropic effects, and targeting specific population segments. This examination is a small observational study, which was conducted without rigorous statistical analysis, and which is limited both by the number of advertisements and by advertising strategies examined. Given the strong parallels between tobacco and tanning advertising methodologies, further consumer education and investigation into the public health risks of indoor tanning is needed.

    This study examined health belief model (HBM) relevant constructs in the context of indoor tanning cessation. Telephone interviews were conducted between December 2011 and April 2012 with participants drawn from the Growing Up Today Study (GUTS) population, specifically, former tanning bed users (N = 14, all females; mean age, 25.65 years) who reported frequent use in 2007, but had quit by 2010. Participants identified important motivations for quitting including health and financial reasons and the central role of family and friends in providing encouragement for indoor tanning cessation. However, participants also noted substantial barriers to maintaining indoor tanning quitting (e.g., social pressures to look good, tanning salon incentives). Participants' experience of withdrawal highlighted psychological factors more often than physical factors; some were open to resuming use in the future. The findings will be useful in intervention development to encourage cessation, the strengthening of policies to regulate the indoor tanning industry, as well as public health messaging to raise awareness of this prevalent, easily accessible cancer risk behavior.

    Two tanning units of Pakistan, namely, Kasur and Mian Channun were investigated with respect to the tanning processes (chrome and vegetable, respectively) and the effects of the tanning agents on the quality of soil in vicinity of tanneries were evaluated. The effluent and soil samples from 16 tanneries each of Kasur and Mian Channun were collected. The levels of selected metals (Na, K, Ca, Mg, Fe, Cr, Mn, Co, Cd, Ni, Pb and Zn) were determined by using flame atomic absorption spectrophotometer under optimum analytical conditions. The data thus obtained were subjected to univariate and multivariate statistical analyses. Most of the metals exhibited considerably higher concentrations in the effluents and soils of Kasur compared with those of Mian Channun. It was observed that the soil of Kasur was highly contaminated by Na, K, Ca and Mg emanating from various processes of leather manufacture. Furthermore, the levels of Cr were also present at much enhanced levels than its background concentration due to the adoption of chrome tanning. The levels of Cr determined in soil samples collected from the vicinity of Mian Channun tanneries were almost comparable to the background levels. The soil of this city was found to have contaminated only by the metals originating from pre-tanning processes. The apportionment of selected metals in the effluent and soil samples was determined by a multivariate cluster analysis, which revealed significant differences in chrome and vegetable tanning processes.

  5. Do tanning salons adhere to new legal regulations? Results of a simulated client trial in Germany.

    2016-03-01

    In August 2009 and January 2012, two regulations were passed in Germany to limit UV exposure in the general population. These regulations state that no minors are allowed to use tanning devices. Personnel of tanning salons is mandated to offer counseling regarding individual skin type, to create a dosage plan with the customer and to provide a list describing harmful effects of UV radiation. Furthermore, a poster of warning criteria has to be visible and readable at all times inside the tanning salon. It is unclear whether these regulations are followed by employees of tanning salons in Germany, and we are not aware of any studies examining the implementation of the regulations at individual salons. We performed a simulated client study visiting 20 tanning salons in the city-state of Bremen in the year 2014, using a short checklist of criteria derived from the legal requirements, to evaluate whether legal requirements were followed or not. We found that only 20 % of the tanning salons communicated adverse health effects of UV radiation in visible posters and other materials and that only 60 % of the salons offered the required determination of the skin type to customers. In addition, only 60 % of the salons offered to complete the required dosage plan with their customers. To conclude, our results suggest that the new regulations are insufficiently implemented in Bremen. Additional control mechanisms appear necessary to ensure that consumers are protected from possible carcinogenic effects of excessive UV radiation.

    IMPORTANCE Indoor tanning is a known carcinogen, but the scope of exposure to this hazard is not known. OBJECTIVE To summarize the international prevalence of exposure to indoor tanning. DATA SOURCES Studies were identified through systematic searches of PubMed (1966 to present), Scopus (1823 to present), and Web of Science (1898 to present) databases, last performed on March 16, 2013. We also hand searched reference lists to identify records missed by database searches and publicly available data not yet published in the scientific literature. STUDY SELECTION Records reporting a prevalence of indoor tanning were eligible for inclusion. We excluded case-control studies, reports with insufficient study information, and reports of groups recruited using factors related to indoor tanning. Two independent investigators performed searches and study selection. Our search yielded 1976 unique records. After exclusions, 161 records were assessed for eligibility in full text, and 88 were included. DATA EXTRACTION AND SYNTHESIS Two independent investigators extracted data on characteristics of study participants, inclusion/exclusion criteria, data collection format, outcomes, and statistical methods. Random-effects meta-analyses were used to summarize the prevalence of indoor tanning in different age categories. We calculated the population proportional attributable risk of indoor tanning in the United States, Europe, and Australia for nonmelanoma skin cancer (NMSC) and melanoma. MAIN OUTCOMES AND MEASURES Ever and past-year exposure to indoor tanning. RESULTS The summary prevalence of ever exposure was 35.7% (95% CI, 27.5%-44.0%) for adults, 55.0% (33.0%-77.1%) for university students, and 19.3% (14.7%-24.0%) for adolescents. The summary prevalence of past-year exposure was 14.0% (95% CI, 11.5%-16.5%) for adults, 43.1% (21.7%-64.5%) for university students, and 18.3% (12.6%-24.0%) for adolescents. These results included data from 406 696 participants. The population

    2012-05-15

    In the present study, green and sustainable method or eco-friendly approaches to tanning process based on unnatural D-amino acids (D-AA)-aldehyde (Ald) as a substitute for chrome-free tanning has been attempted. The distribution of optically active D-AA in tanned leather, the hydrothermal stability, the mechanical properties and resistance to collagenolytic activity of tanned leather, the evaluation of eco-friendly characteristics were investigated. Scanning electron microscopic (SEM) and Atomic force microscopic (AFM) analyses indicate the surface morphology and roughness, respectively, of the tanned leather collagen matrix. Shrinkage and Differential scanning calorimetric (DSC) analyses shows that the shrinkage temperature (T(s)) and denaturation temperature (T(d)) of tanned leather are related to the content of D-AA+Ald present in the leather matrix. It has been found that the T(s) of D-AA tanned leather is more than that of Ald tanned leather and also more or less equal to chrome tanned leather. Environmental impact assessment (EIA) shows that the developed process results in significant reduction in total solids content (TSC) and improves better biodegradability of organic compound present in the effluent compared to chrome tanning.

  8. Testing a social cognitive theory-based model of indoor tanning: implications for skin cancer prevention messages.

    The lack of a theory-based understanding of indoor tanning is a major impediment to the development of effective messages to prevent or reduce this behavior. This study applied the Comprehensive Indoor Tanning Expectations (CITE) scale in an analysis of indoor tanning behavior among sorority women (total N = 775). Confirmatory factor analyses indicated that CITE positive and negative expectations were robust, multidimensional factors and that a hierarchical structure fit the data well. Social cognitive theory-based structural equation models demonstrated that appearance-oriented variables were significantly associated with outcome expectations. Outcome expectations were, in turn, significantly associated with temptations to tan, intention to tan indoors, and indoor tanning behavior. The implications of these findings for the development of messages to prevent and reduce indoor tanning behavior are discussed in two domains: (a) messages that attempt to change broader societal perceptions about tan skin, and (b) messages that focus more narrowly on indoor tanning-challenging positive expectations, enhancing negative expectations, and encouraging substitution of sunless tanning products.

    Use of indoor tanning devices increases risk of cutaneous malignant melanoma, but the association with risk of squamous cell carcinoma (SCC) of the skin is unclear. Cohort studies of SCC risk are rare and we aimed to assess the association between SCC risk and host characteristics, sun exposure, and indoor tanning in a population-based cohort of Norwegian and Swedish women conjunctly with SCC incidence data from national cancer registries. Host characteristics and exposure to sun and indoor tanning devices before 50-years old were recorded by questionnaire at inclusion (30-50 years) in 1991/92. Multivariable relative risks (RRs) and 95% confidence intervals (CIs) were estimated by Poisson regression. During follow-up of 106,548 women through December 2009, SCC was diagnosed in 141 women. Skin sensitivity to acute sun exposure was the most important pigmentation characteristic (RR = 2.73, 95% CI 1.47-5.05, for red with pain/red with pain and blisters versus brown). We found no consistent associations with sunburns and bathing vacations in the first five age decades, but a significant positive trend for bathing vacations summarized over ages 10-49 years (Ptrend  = 0.02). We also found significantly increased risks of SCC following indoor tanning at age 40-49 years (RR = 2.17, 95% CI 1.29-3.67, for ≥ 1 time/month versus never) and indoor tanning summarized over ages 10-49 years (Ptrend  = 0.001). RR for ever versus never use of indoor tanning over ages 10-49 years was 1.93 (95% CI 1.27-2.95). Propensity to burn was an important host characteristic, and bathing vacations and indoor tanning summarized over ages 10-49 years increased SCC risk.

    In this letter, we propose a novel low-temperature nitridation technology on a tantalum nitride (TaN) thin film resistor (TFR) through supercritical carbon dioxide (SCCO2) treatment for temperature sensor applications. We also found that the sensitivity of temperature of the TaN TFR was improved about 10.2 %, which can be demonstrated from measurement of temperature coefficient of resistance (TCR). In order to understand the mechanism of SCCO2 nitridation on the TaN TFR, the carrier conduction mechanism of the device was analyzed through current fitting. The current conduction mechanism of the TaN TFR changes from hopping to a Schottky emission after the low-temperature SCCO2 nitridation treatment. A model of vacancy passivation in TaN grains with nitrogen and by SCCO2 nitridation treatment is eventually proposed to increase the isolation ability in TaN TFR, which causes the transfer of current conduction mechanisms.

  11. The Growing Public Health Challenges of Exposure to Ultraviolet Radiation From Use of Indoor Tanning Devices in the United States.

    Ultraviolet radiation is recognized as a human carcinogen by the International Agency for Research on Cancer, the world's authority on cancer research. In particular, exposure to ultraviolet radiation can lead to melanoma of the skin, which is the deadliest form of skin cancer in the United States. Yet despite the significant public health burden that is associated with skin cancer in the United States, each year over a million Americans engage in indoor tanning where exposure to artificial ultraviolet radiation occurs. In this article, we argue for an immediate ban on the use of commercial indoor tanning by minors and, based on international precedents, the phasing out of all commercial tanning operations in the United States. We consider the use of indoor tanning devices in the United States, epidemiological data on indoor tanning devices and cancer, regulation of tanning devices, and scientific evidence for increased government intervention.

  12. How Do Perceived Descriptive Norms Influence Indoor Tanning Intentions? An Application of the Theory of Normative Social Behavior.

    Indoor tanning bed use is highly influenced by perceived norms about a tanned appearance. The theory of normative social behavior (TNSB) details the many ways in which norms can impact intentions and behavior, but has never been assessed in the context of indoor tanning. Considering this, we conducted a survey among female university students (N = 274) to determine the extent to which the TNSB predicted intentions to use indoor tanning beds. Overall, the path model predicted about 46% of the variance in intentions, and the majority of significant indirect effects were witnessed through the outcome expectation variables included in the TNSB, suggesting that these may be the most salient mechanisms-as predicted by the TNSB-through which norms can impact tanning intentions. In light of these results, theoretical and practical implications are discussed, and specific recommendations are given to extend the predictive utility of the TNSB in the context of indoor tanning.

    Skin cancers are becoming more prevalent even though many can be prevented. Women are more knowledgeable than men about skin cancer, yet they are more likely to sunbathe deliberately and to use artificial tanning equipment. The purpose of this article is to examine messages that women receive about the benefits of a tan. Particularly, we focused on how the indoor UV tanning industry represents the value of a tan to women. We subjected five issues of Smart Tan Canada to thematic analysis. We examined language in advertisements and articles that promote an artificial tan to women. Four themes emerged: Be Beautiful and Sexy; Look Young; Feel Better; and Science, Health, and Nature. These themes are especially effective in a culture that routinely objectifies women and places a high degree of value on their appearance. We suggest that appearance-based interventions, media literacy training, and legislation could counteract the messages in the themes.

    Hydrothermal factors in Ningxia, an arid and semi-arid area in Northwestern China, were examined to determine their influence on the geographical differentiation of the wool quality of Tan sheep lambskin. Prospective areas for extension of the Tan sheep industry were also investigated. Two sheep groups were sampled; one consisted of artificial insemination flocks (1241 lambs sampled from 25 flocks) and the other of natural mating flocks (1009 lambs from 38 flocks). Six phenotypical traits were measured for each lamb and six hydrothermal factors were collected from the meteorological stations located in the sampling areas. A significant correlation was found between wool characteristics of the lambskin and hydrothermal conditions. Data further indicated that among all the hydrothermal factors measured, those causing the geographical differentiation of soil and vegetation were the major factors responsible for the corresponding differentiation of the lambskin and wool quality of Tan sheep. Thermal factors were mostly positively correlated with wool quality, while the influence of moisture was negative. Three eco-geographical regions were defined based on a combination of the hydrothermal conditions and corresponding wool characters: (i) typical region or super-suitable region, (ii) sub-typical region or suitable region and (iii) transitional region. The delimitation could be used as a basis for the extension of the Tan sheep industry. It is also suggested that the wool quality of lambskin of Tan sheep in these three regions could be improved by means of controlled breeding and selection.

    To examine modelling of outcomes relevant to sun protection in Australian women's magazines, content analysis was performed on 538 spring and summer issues of popular women's magazines from 1987 to 2005. A total of 4949 full-colour images of Caucasian females were coded for depth of tan, extent of clothing cover, use of shade and setting. Logistic regression using robust standard errors to adjust for clustering on magazine was used to assess the relationship between these outcomes and year, setting and model's physical characteristics. Most models portrayed outdoors did not wear hats (89%) and were not in shade (87%). Between 1987 and 2005, the proportion of models depicted wearing hats decreased and the proportion of models portrayed with moderate to dark tans declined and then later increased. Younger women were more likely to be portrayed with a darker tan and more of their body exposed. Models with more susceptible phenotypes (paler hair and eye colour) were less likely to be depicted with a darker tan. Darker tans and poor sun-protective behaviour were most common among models depicted at beaches/pools. Implicit messages about sun protection in popular Australian women's magazines contradict public health messages concerning skin cancer prevention.

    Use of ultraviolet radiation-emitting tanning devices has been classified as "carcinogenic to humans" (group 1) by the International Agency for Research on Cancer. Following this classification, the knowledge of typical ultraviolet emission levels from tanning devices can be of interest for evaluating their impact on health. In this work, the results of an extensive measurement campaign on artificial tanning appliances are presented. Ultraviolet emissions from 94 tanning appliances produced by 15 different manufacturers were characterized by onsite spectroradiometric measurements. The measured radiometric quantities were compared with reference values fixed in the European technical standard EN 60335-2-27 "Household and similar electrical appliances-Safety. Part 2: Particular requirements for appliances for skin exposure to ultraviolet and infrared radiation." Measurement results indicate that 88% of the examined appliances had ultraviolet emissions not compliant with the technical standard. Among the considered appliances, tanning devices equipped with low pressure lamps showed higher ultraviolet levels of effective irradiance and less compliance with standard requirements. In particular, UV emissions from 100% of low pressure appliances and from 78% of high pressure appliances exceeded the irradiance limit of 0.3 Wm set by the European technical standard.

    In this article we study the viability of regions of large tan β within the frame-work of Fat Higgs/λ-SUSY Models. We compute the one-loop effective potential to find the corrections to the Higgs boson mass due to the heavy non-standard Higgs bosons. As the tree level contribution to the Higgs boson mass is suppressed at large tan β, these one-loop corrections are crucial to raising the Higgs boson mass to the measured LHC value. By raising the Higgsino and singlino mass parameters, typical electroweak precision constraints can also be avoided. We illustrate these new regions of Fat Higgs/λ-SUSY parameter space by finding regions of large tan β that are consistent with all experimental constraints including direct dark matter detection experiments, relic density limits and the invisible decay width of the Z boson. We find that there exist regions around λ = 1 .25 , tan β = 50 and a uniform psuedo-scalar 4 TeV ≲ M A ≲ 8 TeV which are consistent will all present phenomenological constraints. In this region the dark matter relic abundance and direct detection limits are satisfied by a lightest neutralino that is mostly bino or singlino. As an interesting aside we also find a region of low tan β and small singlino mass parameter where a well-tempered neutralino avoids all cosmological and direct detection constraints.

    Tanned skin has been associated with perceptions of fitness and social desirability. Portrayal of models in magazines may reflect and perpetuate these perceptions. Limited research has investigated tanning shade gradations of models in men's versus women's fitness and muscle enthusiast magazines. Such findings are relevant in light of increased incidence and prevalence of melanoma in the United States. This study evaluated and compared tanning shade gradations of adult Caucasian male and female model images in mainstream fitness and muscle enthusiast magazines. Sixty-nine U.S. magazine issues (spring and summer, 2013) were utilized. Two independent reviewers rated tanning shade gradations of adult Caucasian male and female model images on magazines' covers, advertisements, and feature articles. Shade gradations were assessed using stock photographs of Caucasian models with varying levels of tanned skin on an 8-shade scale. A total of 4,683 images were evaluated. Darkest tanning shades were found among males in muscle enthusiast magazines and lightest among females in women's mainstream fitness magazines. By gender, male model images were 54% more likely to portray a darker tanning shade. In this study, images in men's (vs. women's) fitness and muscle enthusiast magazines portrayed Caucasian models with darker skin shades. Despite these magazines' fitness-related messages, pro-tanning images may promote attitudes and behaviors associated with higher skin cancer risk. To date, this is the first study to explore tanning shades in men's magazines of these genres. Further research is necessary to identify effects of exposure to these images among male readers.

    TanDEM-X is a spaceborne Synthetic Aperture Radar (SAR) mission, whose goal is the generation of a global Digital Elevation Model (DEM) with unprecedented accuracy, by using interferometric SAR (InSAR) techniques (InSAR). TanDEM-X offers a huge global data set of bistatic InSAR acquisitions, each of them supplemented by quick look images of different SAR quantities, such as amplitude, coherence, and DEM. Global quick look mosaics of the interferometric coherence and of the relative height error can be considered for mission performance monitoring and acquisition strategy optimization. The aim of this paper is to present the use of such mosaics within the TanDEM-X mission and to show their potentials for future scientific applications for example in the fields of glaciology and forestry.

    Two laboratory studies were conducted in which a new type of intervention was used to reduce ultraviolet radiation (UV) exposure from tanning booth use among college students (Time 1 Ns=70 and 134). The intervention uses UV photography to highlight the damage to facial skin caused by previous UV exposure. When the authors controlled for baseline measures of booth use, students in both studies who viewed their UV photographs reported less booth use at a follow-up session 3-4 weeks later than did students not shown a copy of their photograph. Also, in both studies, the decline in use was significantly mediated by a Tanning Cognition Index composed of variables suggested by the prototype-willingness (prototype) model of health risk: tanning attitudes, tanner prototypes, and willingness to engage in risky UV exposure.

    Tanning processes performed in drums consume large amounts of water and chemicals, most of which end up in the wastewater. This study explores an alternative approach at an industrial scale to the traditional pickle-chrome tanning method. The new method replaces formic and sulphuric acids with sulphonic aromatic acid. Because it is done without float, there is a sizeable reduction in the amount of added salt and chrome salt as well as an increase in temperatures at the end of the tanning process. From an environmental perspective, the new method offers important advantages. For instance, there is no float addition in the tannage. Also, there are reductions of 94% and 99%, respectively, in the discharge of chlorides and chrome, as well as a 75% reduction in the residual float. Our financial assessment demonstrated that the new method is 42% cheaper than a traditional approach.

    We rated 3971 photographs of models from midsummer editions of six Australian fashion magazines from 1982-1983 to 1990-1991 for tan on a 9-point scale, for the presence of hats, for sun-protective clothing, and for shade setting. With the exception of the 1990-1991 sample, there was an increasing proportion of light tans over the years. Men were more likely to be deeply tanned than were women. The proportion of models wearing hats followed an increasing linear trend across the five periods. Three quarters of the outdoor photographs were taken in unshaded settings. In unshaded settings, 17% of the women and 5% of the men wore hats.

    Background Although skin cancer is largely preventable, it affects nearly 1 of 5 US adults. There is a need for research on how to optimally design persuasive public health indoor tanning prevention messages. Objective The objective of our study was to examine whether framed messages on indoor tanning behavioral intentions delivered through short message service (SMS) text messaging would produce (1) positive responses to the messages, including message receptivity and emotional response; (2) indoor tanning efficacy beliefs, including response efficacy and self-efficacy; and (3) indoor tanning risk beliefs. Methods We conducted a pilot study of indoor tanning prevention messages delivered via mobile phone text messaging in a sample of 21 young adult women who indoor tan. Participants completed baseline measures, were randomly assigned to receive gain-, loss-, or balanced-framed text messages, and completed postexposure outcome measures on indoor tanning cognitions and behaviors. Participants received daily mobile phone indoor tanning prevention text messages for 1 week and completed the same postexposure measures as at baseline. Results Over the 1-week period there were trends or significant changes after receipt of the text messages, including increased perceived susceptibility (P<.001), response efficacy beliefs (P<.001), and message receptivity (P=.03). Ordinary least squares stepwise linear regression models showed an effect of text message exposure on self-efficacy to quit indoor tanning (t6=–2.475, P<.02). Ordinary least squares linear regression including all measured scales showed a marginal effect of SMS texts on self-efficacy (t20=1.905, P=.08). Participants endorsed highly favorable views toward the text messaging protocol. Conclusions This study supports this use of mobile text messaging as an indoor tanning prevention strategy. Given the nature of skin cancer risk perceptions, the addition of multimedia messaging service is another area of potential

    Public health campaigns have improved knowledge on UVR-associated skin cancer risk and increased sun protection awareness. However, tanned skin is still a common beauty ideal. The relationship between knowledge, attitudes and protective behavior is not fully understood yet. A population-based survey was thus performed in the district of Erlangen involving 2,619 parents of 3- to 6-year old children. By means of a self-administered standardized questionnaire parental knowledge about risk factors for skin cancer, their attitudes towards tanning and details of protective measures taken for their children were assessed. The study analyzed specifically the impact of parental tanning attitudes on sun-protective measures for their children while controlling for parental knowledge about skin cancer risk factors. While parental knowledge was significantly (inversely) associated with agreement to the statement "Tanned skin is healthy skin", this was not the case for "Tanning makes me look better". Overall, tanning affirmative attitudes were inversely associated with protective measures taken for the children, whereas parental knowledge had a positive impact on sun protection at the beach only. Multivariable analyses provided evidence for an effect of parental attitude on protective behavior independent of parental knowledge. Tanning attitudes and tanned skin as the misguided ideal of beauty need to be addressed in future public health campaigns to enhance the effectiveness of preventive activities in changing sun protective behavior.

  19. The aryl hydrocarbon receptor mediates UVB radiation-induced skin tanning.

    PubMed

    Jux, Bettina; Kadow, Stephanie; Luecke, Sandra; Rannug, Agneta; Krutmann, Jean; Esser, Charlotte

    2011-01-01

    Melanogenesis is the vital response to protect skin cells against UVB-induced DNA damage. Melanin is produced by melanocytes, which transfer it to surrounding keratinocytes. Recently, we have shown that the aryl hydrocarbon receptor (AhR) is part of the UVB-stress response in epidermal keratinocytes. UVB triggers AhR signaling by generating the AhR ligand 6-formylindolo(3,2-b)carbazole from tryptophan. We show here that normal murine melanocytes express functional AhR. Using standard UVB tanning protocols, AhR-deficient mice were shown to tan significantly weaker than wild-type mice; in these mice, tyrosinase activity in the epidermis was lower as well. Tanning responses and tyrosinase activity, however, were normal in keratinocyte-specific conditional AhR knockout mice, indicating that release of melanogenic keratinocyte factors is unaffected by the UVB-AhR signaling pathway and that the diminished tanning response in AhR(-/-) mice is confined to the level of melanocytes. Accordingly, the number of dihydroxyphenylalanin-positive melanocytes increased significantly less on UVB irradiation in AhR(-/-) mice than in wild-type mice. This difference in melanocyte number was associated with a significantly reduced expression of stem cell factor-1 and c-kit in melanocytes of AhR(-/-) mice. Thus, the environmental signal sensor AhR links solar UVB radiation to skin pigmentation.

    The German Aerospace Center (DLR, Deutsches Zentrum für Luft- und Raumfahrt) currently conducts the bistatic interferometric synthetic aperture radar (SAR) Mission TanDEM-X, which shall result in a DEM of global coverage in an unprecedented resolution and accuracy according to DTED level 3 standard. The mission is based on the two SAR satellites TerraSAR-X and TanDEM-X that have been launched in June 2007 and 2010, respectively. After the commissioning phase of TanDEM satellite and the orbital adjustment the bistatic image acquisition in close formation began end of 2010. The data collection for the mission is scheduled to last about three years, i.e., the bigger part of the required data have been already gathered. Based on this data DLR will conduct several processing steps in order to come up finally with a global and seamless DEM of the Earth's landmass which shall meet the envisaged specifications. Since the entire mission is an endeavor in the framework of a private-public-partnership, the private partner, Astrium, will eventually commercialize the DEM product. In this paper, we will provide an overview of the data collection and the deliverables that will come along with TanDEM-X mission. Furthermore, we will analyze a DEM derived from early stage immediate products of the mission.

  16. In vitro/in vivo and analytical evaluation of sunless tanning formulations containing different rheology modifiers.

    2010-01-01

    In vitro data suggest that different in vivo performances are expected for two dihydroxyacetone (DHA)-containing formulations with similar concentrations of DHA and excipients but different commercially available rheology modifiers: one with a cationic polymer-based rheology modifier (blend) [dimethylacrylamide/ethyltrimonium chloride methacrylate copolymer (and) propylene glycol dicaprylate/dicaprate (and) PPG-1 trideceth-6 (and) C10-11 isoparaffin]; and the other with a polyacrylamide-based rheology modifier (blend) [polyacrylamide (and) C13-14 isoparaffin (and) laureth-7]. Both rheology modifiers (blends) contained comparable levels of polymers and were used at 3% w/w (as supplied). Differences in color development were illustrated in vitro with respect to the yellow/red and lightness/chroma parameters, which were confirmed in the followup in vivo studies. The test article with the cationic polymer-based rheology modifier produced a more natural sunless tan, comparable to a desirable sun-induced tan, for all panelists, one that was more uniform and lasted longer compared with the sunless tan generated by the test article with the polyacrylamide-based rheology modifier. A method for HPLC analysis of DHA in sunless tanning formulations was established and utilized to confirm concentrations of DHA in test articles.

  5. Casting shadows on the prevalence of tanning dependence: an assessment of mCAGE criteria.

    PubMed

    Schneider, Sven; Schirmbeck, Frederike; Bock, Christina; Greinert, Rüdiger; Breitbart, Eckhardt W; Diehl, Katharina

    2015-02-01

    Recently more and more studies have reported high prevalence rates for a 'tanning dependence' among tanning bed users. The authors of these studies base their argumentation on a modified (m) version of the CAGE (Cut-down, Annoyed, Guilty and Eye-opener) Criteria, initially used for alcohol addiction. By means of cognitive interviews and a large population survey, we tested the validity of the mCAGE Criteria and the above-mentioned prevalence that was deduced on the basis of rather small collectives. Firstly, it seems that the mCAGE Criteria wording used so far is inconsistent, misleading and intrinsically invalid. Secondly, our population-based data show a much lower percentage (15%) of current sunbed users with potential dependence symptoms than the above-mentioned previously published studies. Thirdly, the usage parameters for most of the supposed 'addicts' do not indicate a substance addiction: 38% of the users with positive scores reported not having visited a tanning studio at all in the previous month, 39% did not use sunbeds regularly and 89% did not show signs of tolerance to UV radiation. The mCAGE Criteria do not seem suitable for assessing tanning dependence.

  12. Determination of total chromium in tanned leather samples used in car industry.

    PubMed

    Zeiner, Michaela; Rezić, Iva; Ujević, Darko; Steffan, Ilse

    2011-03-01

    Despite the high competition of synthetic fibers leather is nowadays still widely used for many applications. In order to ensure a sufficient stability of the skin matrix against many factors, such as microbial degradation, heat and sweat, a tanning process is indispensable. Using chromium (III) for this purpose offers a multitude of advantages, thus this way of tanning is widely applied. During the use of chromium tanned leather as clothing material as well as for decoration/covering purposes, chromium is extracted from the leather and may then cause nocuous effects to human skin, e.g. allergic reactions. Thus the knowledge of the total chromium content of leather samples expected to come into prolonged touch with human skin is very important. In car industry leather is used as cover for seats, steering wheel and gearshift lever The chromium contents often chromium tanned leather samples used in car industry were determined. First all samples were dried at 65 degrees C overnight and then cut in small pieces using a ceramic knife, weighed and analyzed by inductively coupled plasma--optical emission spectrometry (ICP-OES) after acidic microwave assisted digestion. The total chromium amounts found were in the range from 19 mg/g up to 32 mg/g. The extraction yield of chromium from leather samples in sweat is approximately 2-7%. Thus especially during long journeys in summer chromium can be extracted in amounts which may cause nocuous effects for example on the palm of the hands or on the back.

  19. Recall of indoor tanning salon warnings and safety guidelines among a national sample of tanners.

    2016-12-01

    Indoor tanning (IT) is a known carcinogen, and regulation has increased across the USA. However, there is minimal point-of-sale regulation for adult users. The purpose of the present study is to explore whether IT users recall being provided with warnings or safety guidelines at tanning salons. A national sample of 273 young adult, female IT users (mean age = 22.26, SD = 2.38) was surveyed regarding the frequency that they recalled being provided with six different warnings and safety guidelines when at tanning salons. Between 65 and 90.1 % of participants reported recalling the various warnings and guidelines. Having very fair skin was reported by 16.8 % of participants, and these high-risk individuals were less likely to recall having read and signed a consent form than other IT users (p = .002). The current level of regulation is insufficient to provide IT users with consistent warnings and safety guidelines at tanning salons.

  13. Tanning bed and nail lamp use and the risk of cutaneous malignancy: a review of the literature.

    PubMed

    O'Sullivan, Niamh-Anna; Tait, Clare P

    2014-05-01

    Malignant melanoma (MM) and non-melanoma skin cancer (NMSC) are increasingly common and both can be fatal. In 2009 the World Health Organization (WHO) classified the whole ultraviolet spectrum and tanning beds as carcinogenic to humans, placing them in the same category as asbestos and tobacco. Despite this, the trend for indoor tanning continues. A growing body of evidence has now associated indoor tanning with an increased risk of MM and NMSC. As a result, there has been an upsurge in regulations in the tanning industry ranging from age restrictions to complete bans on commercial tanning. This article examines the evidence and strengthens the case for a complete ban of a recognised modifiable risk factor for cutaneous malignancy.

    TanDEM-X (TerraSAR-X add-on for Digital Elevation Measurements) is an innovative formation-flying radar mission that opens a new era in spaceborne radar remote sensing. The primary objective is the acquisition of a global digital elevation model (DEM) with unprecedented accuracy (12 m horizontal resolution and 2 m relative height accuracy). This goal is achieved by extending the TerraSAR-X synthetic aperture radar (SAR) mission by a second, TerraSAR-X like satellite (TDX) flying in close formation with TerraSAR-X (TSX). Both satellites form together a large single-pass SAR interferometer with the opportunity for flexible baseline selection. This enables the acquisition of highly accurate cross-track interferograms without the inherent accuracy limitations imposed by repeat-pass interferometry due to temporal decorrelation and atmospheric disturbances. Besides the primary goal of the mission, several secondary mission objectives based on along-track interferometry as well as new bistatic and multistatic SAR techniques have been defined, representing an important and innovative asset of the TanDEM-X mission. TanDEM-X is implemented in the framework of a public-private partnership between the German Aerospace Center (DLR) and EADS Astrium GmbH. The TanDEM-X satellite was successfully launched in June 2010 and the mission started its operational data acquisition in December 2010. This paper provides an overview of the TanDEM-X mission and summarizes its actual status and performance. Furthermore, results from several scientific radar experiments are presented that show the great potential of future formation-flying interferometric SAR missions to serve novel remote sensing applications.

    Indoor tanning is associated with increased risk of melanoma, but most evidence comes from case-control studies. Using data from the Norwegian Women and Cancer Study, a large prospective cohort study, we investigated the associations of age at initiation of indoor tanning, duration of tanning-device use, and dose response with melanoma risk and examined the role of indoor tanning in age at melanoma diagnosis. We used Poisson regression to estimate relative risks and 95% confidence intervals for the relationship of indoor tanning to melanoma risk and linear regression to examine age of indoor tanning initiation in relation to age at diagnosis. During follow-up of 141,045 women (1991-2012; mean duration follow-up = 13.7 years), 861 women were diagnosed with melanoma. Melanoma risk increased with increasing cumulative number of tanning sessions (for highest tertile of use vs. never use, adjusted relative risk = 1.32, 95% confidence interval (CI): 1.08, 1.63); P-trend = 0.006. Age at initiation <30 years was associated with a higher risk in comparison with never use (adjusted relative risk = 1.31, 95% CI: 1.07, 1.59). Moreover, women who started indoor tanning prior to 30 years of age were 2.2 years (95% CI: 0.9, 3.4) younger at diagnosis, on average, than never users. This cohort study provides strong evidence of a dose-response association between indoor tanning and risk of melanoma and supports the hypothesis that vulnerability to the harmful effects of indoor tanning is greater at a younger age.

  19. Selective wet etch of a TaN metal gate with an amorphous-silicon hard mask

    2010-11-01

    The appropriate wet etch process for the selective removal of TaN on the HfSiON dielectric with an amorphous-silicon (a-Si) hardmask is presented. SC1 (NH4OH: H2O2: H2O), which can achieve reasonable etch rates for metal gates and very high selectivity to high-k dielectrics and hardmask materials, is chosen as the TaN etchant. Compared with the photoresist mask and the tetraethyl orthosilicate (TEOS) hardmask, the a-Si hardmask is a better choice to achieve selective removal of TaN on the HfSiON dielectric because it is impervious to the SC1 etchant and can be readily etched with NH4OH solution without attacking the TaN and the HfSiON film. In addition, the surface of the HfSiON dielectric is smooth after the wet etching of the TaN metal gate and a-Si hardmask removal, which could prevent device performance degradation. Therefore, the wet etching of TaN with the a-Si hardmask can be applied to dual metal gate integration for the selective removal of the first TaN metal gate deposition.

    In order to investigate the effects of Zhu-tan Tong-luo decoction on the metabolic capacity of cytochrome P450 (CYP) enzymes, a cocktail method was employed to evaluate the activities of CYP2B6, CYP2C19, CYP1A2, CYP3A4, CYP2C9, CYP2D6. The rats were randomly divided into acute Zhu-Tan Tong-Luo decoction group (Low, High), chronic Zhu-Tan Tong-Luo decoction group (Low, High) and control group. The acute group rats were given 0.6, 1.2 g/kg (Low, High) Zhu-tan Tong-luo decoction by intragastric administration for 1 day, and the chronic group for 14 days. Six probe drugs bupropion, omeprazole, phenacetin, testosterone, tolbutamide, and metroprolol were given to rats through intragastric administration, and the plasma concentrations were determined by UPLC-MS/MS. There statistical pharmacokinetics differences for omeprazole, phenacetin, testosterone, tolbutamide, and metroprolol in rats were observed by comparing acute Zhu-tan Tong-luo decoction group with control group; and statistical pharmacokinetics differences for bupropion, omeprazole, phenacetin, testosterone, tolbutamide, and metroprolol were observed by comparing chronic Zhu-Tan Tong-Luo decoction group with control group. After intragastric administration of Zhu-Tan Tong-Luo decoction may slightly induce the activities of CYP2B6, CYP2C19, CYP1A2, CYP3A4, CYP2C9, CYP2D6 of rats. Induction of drug metabolizing enzyme by Zhu-Tan Tong-Luo decoction would reduce the efficacy of other drug. Additional, there no statistical difference for biochemical results after 1 or 14 intragastric administration of Zhu-Tan Tong-Luo decoction.

    Although many countries still face opposition to the legislation of artificial tanning beds, all Australian states and territories have announced a total ban on commercial tanning beds. A combination of epidemiological and policy-centered research, powerful personal stories, and the active advocacy of prominent academics, cancer organizations, and grassroots community campaigners contributed to the decisions to first legislate standards and then ban all commercial tanning beds. We have illustrated that incremental change can be an effective pathway to securing substantial public health reforms.

    The self-tanning agent dihydroxyacetone (DHA) was applied to human skin samples, and its effect on light absorption was followed in time to study the DHA influence inside the different layers of skin. Application of DHA shows increased light absorption in the visible light region, as evidenced by skin tanning. The tanning effect is enhanced by UV irradiation and appears localized in the near-stratum corneum layer as revealed by depth analysis of the time signal. As a reference, application of an emulsion containing titanium dioxide particles shows clear surface stability and a screening of light penetration beyond the stratum corneum.

    Test Area North (TAN) -607, the Technical Support Facility, is located at the north end of the Idaho National Laboratory (INL) Site. U.S. Department of Energy Idaho Operations Office (DOE-ID) is proposing to decommission the northern section of the TAN-607 facility, hereinafter referred to as TAN-607 Hot Shop Area, under a Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) non-time-critical removal action (NTCRA). Despite significant efforts by the United States (U.S.) Department of Energy (DOE) to secure new business, no future mission has been identified for the TAN-607 Hot Shop Area. Its disposition has been agreed to by the Idaho State Historical Preservation Office documented in the Memorandum of Agreement signed October 2005 and it is therefore considered a surplus facility. A key element in DOE's strategy for surplus facilities is decommissioning to the maximum extent possible to ensure risk and building footprint reduction and thereby eliminating operations and maintenance cost. In addition, the DOE's 2006 Strategic Plan is ''complete cleanup of the contaminated nuclear weapons manufacturing and testing sites across the United States. DOE is responsible for the risk reduction and cleanup of the environmental legacy of the Nation's nuclear weapons program, one of the largest, most diverse, and technically complex environmental programs in the world. The Department will successfully achieve this strategic goal by ensuring the safety of the DOE employees and U.S. citizens, acquiring the best resources to complete the complex tasks, and managing projects throughout the United States in the most efficient and effective manner.'' TAN-607 is designated as a historical Signature Property by DOE Headquarters Advisory Council on Historic Preservation and, as such, public participation is required to determine the final disposition of the facility. The decommissioning action will place the TAN-607 Hot Shop Area in a final configuration that

  5. Integration of microwave termination based on TaN thin films on ferrite substrates

    Zhang, Dainan; Ji, Liang; Kolodzey, James

    2015-10-01

    Integration of microwave discrete devices such as isolators and circulators is highly desired for radar and communication platforms and in particular as components used in transmit and receive (T/R) modules. In those applications, Tantalum nitride (TaN) films are widely used as a surface mounted termination to improve the reliability and performance. In the current work, TaN thin films were directly deposited on polycrystalline ferrite substrate (Ni0.3Zn0.7Fe2O4) to be integrated with isolators or circulators. The deposition conditions were first optimized to obtain suitable sheet resistance and near zero temperature coefficients of resistance (TCR). Next a 50 Ω microwave termination was designed and fabricated using standard photolithography techniques. Broadband measurements show that the terminator has a low voltage standing wave ratio (VSWR) of less than 1.20 in the frequency range of DC-20 GHz. The measured resistance was between 48 and 54 Ω.

  6. Morphological changes at Mt. Etna detected by TanDEM-X

    2014-05-01

    We produced a DEM of the Mt. Etna volcano using TanDEM-X data collected on October 9, 2012. The TanDEM-X data were acquired in bistatic mode with TSX as master sensor and TDX as receive only sensor. The pre-existing SRTM DEM was used for geometrical reference (geocoding, initial height model, large scale reference). The interferogram was computed with 4 looks in range and 4 looks in azimuth. After compensation of the SRTM heights, the differential TanDEM-X interferogram looked overall quite flat but showed local deviations related to noise (e.g. over the sea), topographic effects related to the low resolution of the SRTM DEM, and deviations related to actual changes of the topography, as observed in the Mount Etna peak region. After phase unwrapping, addressed with a minimum-cost flow algorithm and slight spatial filtering, the unwrapped phases were converted to relative heights. In order to move to absolute heights the SRTM height reference was used under the assumption that the deviation from the SRTM DEM is zero at large scale and without any linear trend. Finally, the height model was resampled into geographical coordinates. In the framework of the MED-SUV project, and thanks to the availability of a dense GPS network of more than 100 benchmarks periodically measured by INGV_OE, the TanDEM-X model has been validated. By computing the difference of the elevations provided by TanDEM-X with those measured by GPS we obtained a mean difference of 0.7 m and a standard deviation of 5.2 m. These values are biased by a few GPS benchmarks located in steep areas unfavorable illuminated by the radar. Without considerations of the two more unfavorable GPS stations, the height mean difference and a standard deviation are 0.6 m and 4.3 m respectively. We also performed correlation analyses of the height differences with respect to topography, latitude and longitude and we could exclude any elevation-related errors or geometrical ramp distortions. In the following, we compared

    The TanDEM-X formation employs two separate spacecraft to collect interferometric Synthetic Aperture Radar (SAR) measurements over baselines of about 1 km. These will allow the generation ofa global Digital Elevation Model (DEM) with an relative vertical accuracy of 2-4 m and a 10 m ground resolution. As part of the ground processing, the separation of the SAR antennas at the time of each data take must be reconstructed with a 1 mm accuracy using measurements from two geodetic grade GPS receivers. The paper discusses the TanDEM-X mission as well as the methods employed for determining the interferometric baseline with utmost precision. Measurements collected during the close fly-by of the two GRACE satellites serve as a reference case to illustrate the processing concept, expected accuracy and quality control strategies.

    Terrain aided navigation (TAN) is an efficient way to periodically correct the error accumulation of INS. The imaging laser radar is an ideal imaging sensor in TAN for the low-flying aircraft and unmanned air vehicles for the high precision multi-dimensional data acquisition capability and concealable attribute. In this paper, a new framework for applying the laser radar to terrain aided navigation is put forward. Then a new adaptive fused Kalman Filter is proposed to improve the accuracy and robustness. At last, the key factors affected the algorithm are analyzed and the comparative experimentations are presented. The simulating experiments show that the proposed algorithm improves the location accuracy, and has good initial error tolerance and fine robustness. It shows that this approach is a valid solution for the application.

    Dimorphic traits are ubiquitous in nature, but the evolutionary factors leading to dimorphism are largely unclear. We investigate a potential case of sexual mimicry in Drosophila erecta, in which females show contrasting resemblance to males. We map the genetic basis of this sex-limited colour dimorphism to a region containing the gene tan. We find a striking signal of ancient balancing selection at the ‘male-specific enhancer' of tan, with exceptionally high sequence divergence between light and dark alleles, suggesting that this dimorphism has been adaptively maintained for millions of years. Using transgenic reporter assays, we confirm that these enhancer alleles encode expression differences that are predicted to generate this pigmentation dimorphism. These results are compatible with the theoretical prediction that divergent phenotypes maintained by selection can evolve simple genetic architectures. PMID:26778363

    In the minimal supergravity model (MSUGRA), as the parameter tanβ increases, the charged Higgs boson and light bottom squark masses decrease, which can potentially increase contributions from tH+/-, g~b~j and Z~ib~j loops in the decay b-->sγ. We update a previous QCD improved b-->sγ decay calculation to include in addition the effects of gluino and neutralino loops. We find that, in the MSUGRA model, loops involving charginos also increase, and dominate over tW, tH+/-, g~q~ and Z~iq~ contributions for tanβ>~5-10. We find for large values of tanβ~35 that most of the parameter space of the MSUGRA model for μ<0 is ruled out due to too large a value of branching ratio B(b-->sγ). For μ>0 and large tanβ, most of parameter space is allowed, although the regions with the least fine-tuning (low m0 and m1/2) are ruled out due to too low a value of B(b-->sγ). We compare the constraints from b-->sγ to constraints from the neutralino relic density, and to expectations for sparticle discovery at CERN LEP2 and the Fermilab Tevatron pp¯ colliders. Finally, we show that non-universal GUT scale soft breaking squark mass terms can enhance gluino loop contributions to b-->sγ decay rate even if these are diagonal.

  18. Foundations and self-tanning products: Do they provide any protection from the sun?

    As soon as the weather turns sunny, everyone wants a tan. People with skin phototypes III and IV, called melanocompetent, have no problem meeting this fashion requirement. But things are quite different for people with phototypes I and II and so these individuals look for alternative solutions. In essence, light skin burns easily when exposed to the sun. Therefore, light-skinned people are offered a cosmetic solution through self-tanning products or foundations. It seemed interesting to us to evaluate the sun protection power of this type of product. To do this, we used an in vitro method to determine the typical indicators related to sunscreen products, such as sun protection factor (SPF), ultraviolet (UV)-A protection factor (PF-UVA), UV-B/UV-A ratio as well as the critical wavelength because these artificial tanning products could be considered sunscreen products by users. It is important to know whether a self-tanning product and/or a foundation provide sun protection and whether they meet the standards set for other sunscreen products. Protection which is imbalanced for either UV-B or UV-A radiation is potentially harmful for users believing themselves adequately protected. To do this, we assembled the requisite conditions for forming melanoidins in the cosmetic itself. We tested seven amino acids found in the corneal cells of the epidermis. Regardless of the amino acid used, the corresponding SPF was essentially zero (approximately SPF 2). Foundations, on the other hand, proved to be much more interesting because they possess a non-negligible SPF as well as good photostability making these products safe in terms of their mode of application (applied once daily).

    We employ ab initio calculations to investigate energetics of point defects in metastable rocksalt cubic Ta-N and Mo-N. Our results reveal a strong tendency to off-stoichiometry, i.e. defected structures are surprisingly predicted to be more stable than perfect ones with 1:1 metal-to-nitrogen stoichiometry. Despite the similarity of Ta-N and Mo-N systems in exhibiting this unusual behaviour, we also point out their crucial differences. While Ta-N significantly favours metal vacancies, Mo-N exhibits similar energies of formation regardless of the vacancy type (V Mo, V N) as long as their concentration is below ≈ 15~\\text{at}. % . The overall lowest energies of formation were obtained for \\text{T}{{\\text{a}}0.78}\\text{N} and \\text{M}{{\\text{o}}0.91}\\text{N} , which are hence predicted to be the most stable compositions. To account for various experimental conditions during synthesis, we further evaluated the phase stability as a function of chemical potential of individual species. The proposed phase diagrams reveal four stable compositions, \\text{M}{{\\text{o}}0.84}\\text{N} , \\text{M}{{\\text{o}}0.91}\\text{N} , \\text{Mo}{{\\text{N}}0.69} and \\text{Mo}{{\\text{N}}0.44} , in the case of Mo-N and nine stable compositions in the case of Ta-N indicating the important role of metal under-stoichiometry, since \\text{T}{{\\text{a}}0.75}\\text{N} and \\text{T}{{\\text{a}}0.78}\\text{N} significantly dominate the diagram. This is particularly important for understanding and designing experiments using non-equilibrium deposition techniques. Finally, we discuss the role of defect ordering and estimate a cubic lattice parameter as a function of defect contents and put them in the context of existing literature theoretical and experimental data.

    Keratin 83 (KRT83) is an important keratin protein in hair development. In this study, expression of KRT83 was compared among different tissues and between 1-month-old lambs and 48-month adult of Chinese Tan sheep, which showed different fleece phenotypes. The results showed that KRT83 was only expressed in skin, and KRT83 mRNA level in skin was significantly higher in Tan lambs than in adult sheep. To further understand the expression regulation of KRT83 by transcription factors in Tan sheep, amplified sequences coving different ranges of KRT83 promoter region were inserted into a pGL3-basic vector and then transfected into sheep primary fibroblast cells. Luciferase assay indicated that the sequence from -218bp to -10bp in the KRT83 promoter induced the highest transcription activity of the vector in the fibroblast cells. Transcription factor adenylate cyclase-associated protein 1 (CAP1) was predicted by online tools within this region. Electrophoretic mobility shift assay (EMSA) confirmed binding of the purified CAP1 protein to the target core region from -88bp to -10bp, because mutation in the target core sequence resulted in failure of CAP1 binding to the target region. Moreover, overexpression of CAP1 protein led to repression of the KRT83 promoter activity in sheep primary fibroblast cells, and expression of CAP1 was lower in lambs than in adult sheep. Therefore, we concluded that CAP1 is a key transcription factor involved in negative regulation of KRT83 expression in Tan sheep skin. Our study provides new insights into the transcriptional regulation of KRT83 and further hints of its critical role in curly hair phenotype in sheep.

    Tan spot, caused by the fungus Pyrenophora triticirepentis, is economically important foliar disease in Latvia, Lithuania, and Romania; however, race structure from Baltic States and Romania is not known. In this study, we performed genotypic and phenotypic race characterization of a large collection of P. triticirepentis isolates from these countries to determine race structure and utilize this information for better disease management and breeding wheat for tan spot resistance. We characterized 231 single spore isolates from Latvia (n = 15), Lithuania (n = 107), and Romania (n = 109) for Ptr ToxA and Ptr ToxB genes using two genes specific primers. A subset (139) of 231 isolates were further characterized for their race structure by inoculating them individually on tan spot wheat differentials set. Majority (83%) of the 231 isolates amplified Ptr ToxA gene suggesting prevalence of race 1 and 2. Further, phenotypic characterization of 139 isolates also showed wide prevalence of races 1 (68%), 2 (8%), 3 (11%), and 4 (5%) were also identified from Baltic States as well as Romania. Eighteen of the isolates (13%) did not seem to be of any of the eight known races as they lacked Ptr ToxA gene but they behaved like either race 1 or race 2, suggesting possibility of novel toxins in these isolates as their virulence tools.

    The tanning industry is of great economic importance worldwide; however, the potential environmental impact of tanning is significant. An important component in tanning is the removal of hair from the hide (unhairing), a process which generates considerable amounts of toxic effluent characterized by a high concentration of sulphur, rich mineral compounds, a high alkalinity and a high organic load. The purpose of the work described here was to evaluate the biodegradability of the unhairing wastewater by endogenous biomass in batch culture and continuous systems. The detoxification of the effluent was assessed by seed germination tests. The batch culture experiments showed that variations in COD, temperature and pH significantly affected the endogenous biomass growth and activity. The optimal treatment condition corresponded to an initial COD of 6 g/L, pH of 7 and 30 degrees C. Under continuous culture conditions, the reactor was fed for 48 days with the unhairing effluent. The optimal COD removal efficiency was 85.5%. During treatment, a transformation of sulphides into thiosulphates and then sulphates was also observed. The effect of untreated and treated unhairing wastewater on seed germination of different plant species was studied. The data suggested that treatment decreased the wastewater toxicity. Indeed, germination was inhibited when the effluent dilution was lower than 20% and 10% for treated and untreated wastewater, respectively.

  4. Tropical forest heterogeneity from TanDEM-X InSAR and lidar observations in Indonesia

    Fires exacerbated during El Niño Southern Oscillation are a serious threat in Indonesia leading to the destruction and degradation of tropical forests and emissions of CO2 in the atmosphere. Forest structural changes which occurred due to the 1997-1998 El Niño Southern Oscillation in the Sungai Wain Protection Forest (East Kalimantan, Indonesia), a previously intact forest reserve have led to the development of a range of landcover from secondary forest to areas dominated by grassland. These structural differences can be appreciated over large areas by remote sensing instruments such as TanDEM-X and LiDAR that provide information that are sensitive to vegetation vertical and horizontal structure. One-point statistics of TanDEM-X coherence (mean and CV) and LiDAR CHM (mean, CV) and derived metrics such as vegetation volume and canopy cover were tested for the discrimination between 4 landcover classes. Jeffries-Matusita (JM) separability was high between forest classes (primary or secondary forest) and non-forest (grassland) while, primary and secondary forest were not separable. The study tests the potential and the importance of potential of TanDEM-X coherence and LiDAR observations to characterize structural heterogeneity based on one-point statistics in tropical forest but requires improved characterization using two-point statistical measures.

    Digital Elevation Model (DEM) is a key input for the development of risk management systems. Main limitation of the current available DEM is the low level of resolution. DEMs such as STRM 90m or ASTER are globally available free of charge, but offer limited use, for example, to flood modelers in most geographic areas. TanDEM-X (TerraSAR-X add-on for Digital Elevation Measurement), the first bistatic SAR can fulfil this gap. The mission objective is the generation of a consistent global digital elevation model with an unprecedented accuracy according to the HRTI-3 (High Resolution Terrain Information) specifications. The mission opens a new era in risk assessment. In the framework of ALTAMIRA INFORMATION research activities, the DIAPASON (Differential Interferometric Automated Process Applied to Survey Of Nature) processing chain has been successfully adapted to TanDEM-X CoSSC (Coregistered Slant Range Single Look Complex) data processing. In this study the capability of CoSSC data for DEM generation is investigated. Within the on-going FP7 RASOR project (Rapid Analysis and Spatialisation and Of Risk), the generated DEM are compared with Intermediate DEM derived from the TanDEM-X first global coverage. The results are presented and discussed.

    Heavy metals represent an important ecological and health hazard due to their toxic effects and their accumulation throughout the food chain. Conventional techniques commonly applied to recover chromium from tanning wastewaters have several disadvantages whereas biosorption has good metal removal performance from large volume of effluents. To date most studies about chromium biosorption have been performed on simulated effluents bypassing the problems due to organic or inorganic ligands present in real industrial wastewaters that may sequestrate the Cr(III) ions. In the present study a tanning effluent was characterized from a mycological point of view and different fungal biomasses were tested for the removal of Cr(III) from the same tanning effluent in which, after the conventional treatments, Cr(III) amount was very low but not enough to guarantee the good quality of the receptor water river. The experiments gave rise to promising results with a percentage of removed Cr(III) up to 40%. Moreover, to elucidate the mechanisms involved in biosorption process, the same biomasses were tested for Cr(III) removal from synthetic aqueous solutions at different Cr(III) concentrations.

  7. Radiation induced graft copolymerization of methyl methacrylate onto chrome-tanned pig skins

    NASA Astrophysics Data System (ADS)

    Pietrucha, K.; Pȩkala, W.; Kroh, J.

    Graft copolymerization of methyl methacrylate (MMA) onto chrome-tanned pig skins was carried out by the irradiation with 60Co ?-rays. The grafted polymethyl methacrylate (PMMA) chains were isolated by acid hydrolysis of the collagen backbone in order to characterize the graft copolymers. Proof of grafting was obtained through the detection of amino acid endgroups in the isolated grafts by reaction with ninhydrin. The grafting yield of MMA in aqueous emulsion was found to be higher than that for pure MMA and MMA in acetone. The degree of grafting increases with increasing monomer concentration in emulsion and reaches maximum at radiation dose ca 15 kGy. The yield of grafting is very high - ca 90% of monomer converts into copolymer and only 10% is converted into homopolymer. The present paper reports the physical properties of chrome-tanned pig skins after graft polymerization with MMA in emulsion. Modified leathers are more resistant against water absorption and abrasion in comparison with unmodified ones. They have more uniform structure over the whole surface, greater thickness and stiffness. The results reported seem to indicate that MMA may be used in the production of shoe upper and sole leathers. The mechanism of some of the processes occuring during radiation grafting of MMA in water emulsion on tanned leathers has been also suggested and discussed.

    The energetic igniters through integrating B/Ti nano-multilayers on tantalum nitride (TaN) ignition bridge are designed and fabricated. The X-ray diffraction (XRD) and temperature coefficient of resistance (TCR) results show that nitrogen content has a great influence on the crystalline structure and TCR. TaN films under nitrogen ratio of 0.99 % exhibit a near-zero TCR value of approximately 10 ppm/°C. The scanning electron microscopy demonstrates that the layered structure of the B/Ti multilayer films is clearly visible with sharp and smooth interfaces. The electrical explosion characteristics employing a capacitor discharge firing set at the optimized charging voltage of 45 V reveal an excellent explosion performance by (B/Ti) n /TaN integration film bridge with small ignition delay time, high explosion temperature, much more bright flash of light, and much large quantities of the ejected product particles than TaN film bridge.

    The eco-friendly combination tanning process has been developed to reduce chromium in existing researches, which is based on zinc tanning agents. This can be considered as a less-chrome substitute for current tanning process. To gain deeper understanding of the binding mechanisms of zinc-collagen interaction, which are affected by tanning pH, experiments have been carried out. Analysis in this paper reveals how chemical bonds from the collagen's main function groups combine with zinc. XPS and NIR data was analyzed for further understanding of where the zinc binding sites lie on collagen fibers at different pH. The results indicate that high pH is helpful to amino-binding sites while low pH promotes carboxyl-binding sites on collagen fibers. Furthermore, from the effect of Zinc-chrome combination tanning, we can see that the new method reduces the chromium dosage in tanning process compared to the conventional chrome tanning method.

    The topics and framing of news stories relevant to skin cancer prevention have shifted over time. This study examined agenda-setting effects of such news stories on public attitudes and beliefs about tanning and skin cancer. Content analysis data on 516 articles published in two major daily newspapers in Melbourne, Australia, from 1994 to 2007 were combined with circulation data to generate indices of potential news exposure. Associations between these indices and cross-sectional telephone survey data from the same period on 6,244 adults' tanning attitudes and perceived susceptibility to skin cancer were examined using logistic regression models, accounting for the temporal precedence of news content. Pro-sun protection stories on attitudes and behavior were associated with older adults not thinking a tan looks healthy. Pro-sun protection stories on solaria were associated with less preference for a deep tan among young adults who like to suntan. Stories on vitamin D that were unsupportive of or ambiguous about sun protection were associated with a number of pro-tan attitudes among younger adults. Results indicate news coverage during 1994-2007 served an important agenda-setting role in explaining the public's attitudes and beliefs about tanning and skin cancer. Vitamin D stories appeared most influential, particularly among young adults.

    The petrography, age, and paleomagnetism were determined on basalt from 21 lava flows comprising about 1,700 feet of core from two coreholes (TAN CH No. 1 and TAN CH No. 2) in the Test Area North (TAN) area of the Idaho National Engineering Laboratory (INEL). Paleomagnetic studies were made on two additional cores from shallow coreholes in the TAN area. K-Ar ages and paleomagnetism also were determined on nearby surface outcrops of Circular Butte. Paleomagnetic measurements were made on 416 samples from four coreholes and on a single site in surface lava flows of Circular Butte. K-Ar ages were measured on 9 basalt samples from TAN CH No. 1 and TAN CH No. 2 and one sample from Circular Butte. K-Ar ages ranged from 1.044 Ma to 2.56 Ma. All of the samples have reversed magnetic polarity and were erupted during the Matuyama Reversed Polarity Epoch. The purpose of investigations was to develop a three-dimensional stratigraphic framework for geologic and hydrologic studies including potential volcanic hazards to facilities at the INEL and movement of radionuclides in the Snake River Plain aquifer.

    Dear Editor, Ultraviolet (UV) radiation is a well-known physical hazard responsible for photoaging, photoallergic, and phototoxic reactions as well as carcinogenesis, including life-threatening melanomas (1,2). Overexposure to both natural and artificial UV radiation is a public health concern. 30% of cancers diagnosed worldwide are skin cancers. Approximately three million non-melanoma skin cancers and 132 000 new cases of melanomas are diagnosed globally each year (3). Sunburns, especially in childhood, are a very important risk factor for melanomas. Several studies demonstrated a positive association between sunbed use and an increased incidence of malignant melanoma (4). Current medical and cosmetology students will soon be knowledge providers about the risks of excessive exposure to UV radiation and prophylaxis of its consequences. Our aim was to evaluate their knowledge about the side effects of ultraviolet radiation and tanning behaviors. Details on the knowledge and habits of students were obtained during classes at the Poznan University of Medical Sciences. With approval from the Institutional Bioethical Committee, a 41-question anonymous survey was conducted in the spring of 2012 among 190 medical (1-6 year) and cosmetology students (1-5 year). The mean age of the study group was 22.3 years (standard deviation (SD) = 2.4 years), range 19-28 years. The survey was composed of closed and open-ended questions prepared by the authors. The first part of the form included demographic data: gender, age, degree course, and school year. The students were also asked about their reaction to sunlight, sunburns in childhood, and personal and family history of skin cancers or dysplastic nevus syndrome. The factual section of the survey contained questions evaluating responder knowledge about sunbeds and risk of UV radiation as well as their personal tanning habits. The open-ended questions asked responders to provide definitions of: skin phototype, sun protection factor

    In 2015, the U.S. Geological Survey, in cooperation with the U.S. Department of Energy, drilled and constructed boreholes TAN-2271 and TAN-2272 for stratigraphic framework analyses and long-term groundwater monitoring of the eastern Snake River Plain aquifer at the Idaho National Laboratory in southeast Idaho. Borehole TAN-2271 initially was cored to collect continuous geologic data, and then re-drilled to complete construction as a monitor well. Borehole TAN-2272 was partially cored between 210 and 282 feet (ft) below land surface (BLS) then drilled and constructed as a monitor well. Boreholes TAN-2271 and TAN-2272 are separated by about 63 ft and have similar geologic layers and hydrologic characteristics based on geologic, geophysical, and aquifer test data collected. The final construction for boreholes TAN-2271 and TAN-2272 required 10-inch (in.) diameter carbon-steel well casing and 9.9-in. diameter open-hole completion below the casing to total depths of 282 and 287 ft BLS, respectively. Depth to water is measured near 228 ft BLS in both boreholes. Following construction and data collection, temporary submersible pumps and water-level access lines were placed to allow for aquifer testing, for collecting periodic water samples, and for measuring water levels.Borehole TAN-2271 was cored continuously, starting at the first basalt contact (about 33 ft BLS) to a depth of 284 ft BLS. Excluding surface sediment, recovery of basalt and sediment core at borehole TAN-2271 was better than 98 percent. Based on visual inspection of core and geophysical data, material examined from 33 to 211ft BLS primarily consists of two massive basalt flows that are about 78 and 50 ft in thickness and three sediment layers near 122, 197, and 201 ft BLS. Between 211 and 284 ft BLS, geophysical data and core material suggest a high occurrence of fractured and vesicular basalt. For the section of aquifer tested, there are two primary fractured aquifer intervals: the first between 235 and

    Australian states have introduced an outright ban on commercial artificial tanning sunbeds. This was based on evidence from systematic reviews affirming a strong association between tanning bed use and increased risk of melanoma. The implementation of the ban provides an opportunity to assess the effectiveness of the legislation in preventing access to artificial UV radiation. Compliance with the ban has been enforced and monitored by government departments. We additionally monitored online tanning bed advertisements before and after the ban, showing a decline over time in the number of sunbeds advertised for sale on gumtree.com.au and ebay.com.au, from a peak of 115 advertisements in May 2014 to 50 or fewer per month from February 2015. There was also an increase in advertised price, with the percentage of sunbeds offered in Victoria on gumtree.com.au at higher than $2 000 increasing from around 25% between January and June 2014 to 65% in the quarter following the introduction of the ban. Advertisements on gumtree.com.au from individuals wishing to access a sunbed in a private home in Victoria increased from only isolated instances in the months immediately prior to the ban, to between 25 and 77 advertisements per month in the quarter following the ban. In summary, the introduction of an outright ban of commercial sunbeds has achieved a dramatic reduction in the availability of harmful artificial UV radiation sources in Australia. Long-term benefits to the health of the population and a reduction in costs to the health system are expected to result.

    The TanSat carbon satellite is to be launched at the end of 2016. In order to verify the performance of its instruments, a flight test of TanSat instruments was conducted in Jilin Province in September, 2015. The flight test area covered a total area of about 11,000 km² and the underlying surface cover included several lakes, forest land, grassland, wetland, farmland, a thermal power plant and numerous cities and villages. We modeled the column-average dry-air mole fraction of atmospheric carbon dioxide (XCO₂) surface based on flight test data which measured the near- and short-wave infrared (NIR) reflected solar radiation in the absorption bands at around 760 and 1610 nm. However, it is difficult to directly analyze the spatial distribution of XCO₂ in the flight area using the limited flight test data and the approximate surface of XCO₂, which was obtained by regression modeling, which is not very accurate either. We therefore used the high accuracy surface modeling (HASM) platform to fill the gaps where there is no information on XCO₂ in the flight test area, which takes the approximate surface of XCO₂ as its driving field and the XCO₂ observations retrieved from the flight test as its optimum control constraints. High accuracy surfaces of XCO₂ were constructed with HASM based on the flight's observations. The results showed that the mean XCO₂ in the flight test area is about 400 ppm and that XCO₂ over urban areas is much higher than in other places. Compared with OCO-2's XCO₂, the mean difference is 0.7 ppm and the standard deviation is 0.95 ppm. Therefore, the modelling of the XCO₂ surface based on the flight test of the TanSat instruments fell within an expected and acceptable range.

    TanDEM-X (TerraSAR-X add-on for Digital Elevation Measurement) is the first Synthetic Aperture Radar (SAR) mission using close formation flying for bistatic SAR interferometry. The primary goal of the mission is to generate a global digital elevation model (DEM) with 2 m height precision and 10 m ground resolution from the configurable SAR interferometer with space baselines of a few hundred meters. As a key mission requirement for the interferometric SAR processing, the relative position, or baseline vector, of the two satellites must be determined with an accuracy of 1 mm (1D RMS) from GPS measurements collected by the onboard receivers. The operational baseline products for the TanDEM-X mission are routinely generated by the German Research Center for Geosciences (GFZ) and the German Space Operations Center (DLR/GSOC) using different software packages (EPOS/BSW, GHOST) and analysis strategies. For a further independent performance assessment, TanDEM-X baseline solutions are generated at the Astronomical Institute of the University of Bern (AIUB) on a best effort basis using the Bernese Software (BSW). Dual-frequency baseline solutions are compared for a 1-month test period in January 2011. Differences of reduced-dynamic baseline solutions exhibit a representative standard deviation (STD) of 1 mm outside maneuver periods, while biases are below 1 mm in all directions. The achieved baseline determination performance is close to the mission specification, but independent SAR calibration data takes acquired over areas with a well known DEM from previous missions will be required to fully meet the 1 mm 1D RMS target. Besides the operational solutions, single-frequency baseline solutions are tested. They benefit from a more robust ambiguity fixing and show a slightly better agreement of below 1 mm STD, but are potentially affected by errors caused by an incomplete compensation of differential ionospheric path delays.

    The triangular flap repair is one of the most common techniques used in cleft lip surgery. However, inability to address the nasal deformity and loss of orbicularis wholeness accompanied with incomplete reorientation have been two major handicaps of the triangular repair. Therefore, we developed our personal technique, called the triangular with ala nasi (TAN) repair, including a perialar incision and a distinct approach to the skin and muscle. We applied the TAN technique to 32 consecutive (19 male and 13 female) patients with unilateral cleft. The mean age at repair was 2.5 (1-32) years. The cleft lip appeared completely and incompletely in 11 and 21 patients, respectively. The postoperative outcomes were assessed subjectively by Williams test and objectively by Lindsay-Farkas method.The mean follow-up time was 17.1 months. No early complication involving hematoma, infection, wound dehiscence, or partial or total flap loss was encountered. The recoveries of 79.1% and 86.2% on average, when compared with the noncleft side, were obtained postoperatively. With our technique, we aimed at combining the useful properties of the two popular techniques, Millard and Tennison-Randall. The TAN repair lengthens the vertical lip using a triangular flap, resulting in a nonlinear, zig-zag scar on the philtral ridge and forming a symmetrical cupid's bow, superiorities of the Tennison-Randall repair. On the other hand, our method also presents an excellent approximation of both the deep and superficial muscle groups and reduces the nasal deformity with a perialar incision, features of the Millard's technique.

    A rice (Oryza sativa L.) semi-dwarf cultivar, Tan-Ginbozu (d35Tan-Ginbozu), contributed to the increase in crop productivity in Japan in the 1950s. Previous studies suggested that the semi-dwarf stature of d35Tan-Ginbozu is caused by a defective early step of gibberellin biosynthesis, which is catalyzed by ent-kaurene oxidase (KO). To study the molecular characteristics of d35Tan-Ginbozu, we isolated 5 KO-like (KOL) genes from the rice genome, which encoded proteins highly homologous to Arabidopsis and pumpkin KOs. The genes (OsKOL1 to 5) were arranged as tandem repeats in the same direction within a 120 kb sequence. Expression analysis revealed that OsKOL2 and OsKOL4 were actively transcribed in various organs, while OsKOL1 and OsKOL5 were expressed only at low levels; OsKOL3 may be a pseudogene. Sequence analysis and complementation experiments demonstrated that OsKOL2 corresponds to D35. Homozygote with null alleles of D35 showed a severe dwarf phenotype; therefore, d35Tan-Ginbozu is a weak allele of D35. Introduction of OsKOL4 into d35Tan-Ginbozu did not rescue its dwarf phenotype, indicating that OsKOL4 is not involved in GA biosynthesis. OsKOL4 and OsKOL5 are likely to take part in phytoalexin biosynthesis, because their expression was promoted by UV irradiation and/or elicitor treatment. Comparing d35Tan-Ginbozu with other high yielding cultivars, we discuss strategies to produce culm architectures suitable for high crop yield by decreasing GA levels.

    We consider the chargino contribution to CP violation in B→φKS decay in the minimal supersymmetric standard model at large tan β. It is shown that the Wilson coefficient C8g of the chromomagnetic penguin operator can be significantly enhanced by the chargino-mediated diagrams while satisfying other direct or indirect experimental constraints. The enhanced C8g allows a large deviation in the CP asymmetry from the standard model prediction, especially it can explain the apparent anomaly reported by BaBar and Belle.

    The measurement of the change in above ground biomass (AGB) is key for understanding the carbon sink/source nature of tropical forests. Interferometric X-band radar from the only orbiting interferometer, TanDEM-X, shows sensitivity to standing biomass up to at least 300 Mg/ha. This sensitivity may be due in part to the propagation of the shorter X-band wavelength (0.031 m) through holes in the canopy. This talk focuses on estimating the change in AGB over time. Interferometric baselines from TanDEM-X have been obtained in Tapajós National Forest in the Brazilian Amazon over a 4-year period, from 2011 to 2015. Lidar measurements were also acquired during this period. Field measurements of height, height-to-base-of-crown, species, diameter, and position were acquired in 2010, 2013, and 2015. We show interferometric phase height changes, and suggest how these phase height changes are related to biomass change. First we show height changes between baselines separated by one month, over which we expect no change in AGB, to evaluate precision. We find an RMS of <2 m for ~85 stands in the phase height over one month, corresponding to about a 10% measurement of change, which suggests we can detect about a 17 Mg/ha change in AGB at Tapajos. In contrast, interferometric height changes over the period 2011 to 2014 have larger RMS scatters of > 3 m, due to actual change. Most stands show changes in interferometric phase height consistent with regrowth (~10 Mg/ha/yr), and several stands show abrupt, large changes in phase height (>10 m) due to logging and natural disturbance. At the end of 2015, we will acquire more TanDEM-X data over Tapajos, including an area subjected to selective logging. We are doing "before" (March 2015) and "after" (October 2015) fieldwork to be able to understand the signature of change due to selective logging in TanDEM-X interferometric data.

    A grounded theory study was undertaken to describe how adolescents make decisions about sunbathing during the transition from childhood to adolescence and to propose an explanation for the relationships among factors affecting the adoption of sun tanning. In-depth interviews (n = 40) were conducted separately with adolescents (aged 12 to 16 years) and their parents. Constant comparative analysis of adolescents' accounts identified two methods that adolescents described as a means of getting a suntan: intentional sun tanning and incidental sun tanning. The process of adolescents' decision-making about getting a suntan can be understood by examining the following sequence: becoming motivated to get a tan, experimenting with sun tanning, and establishing self as an intentional tanner or incidental tanner. Implications for developing strategies to prevent the adoption of sun-tanning habits among adolescents are presented.

    The recent Surgeon General's call-to-action to prevent skin cancer indicates an urgent need for research on messages to deter young women from tanning indoors. Answering this call, the current study assessed differences in the potential effectiveness of pictorial indoor tanning messages. We randomly assigned undergraduate female participants (N = 568) to one of three message conditions visually depicting health effects, appearance damage, or immediate risks, or to a text-only control. All participants viewed three messages within their condition and answered questions after message exposure. Factorial ANOVAs indicated that compared to the text-only condition, pictorial messages produced greater negative emotional reactions and were perceived as more effective than text-only messages. Text-only messages, however, were significantly more believable than pictorial messages. We observed several differences among the pictorial conditions and among the messages within the pictorial conditions. We conclude that messages discouraging indoor tanning should use pictorial messages illustrating the negative health and appearance damaging effects of indoor tanning, focusing on particular health and appearance consequences. Additional research is needed to guide the selection of images that are believable and will most discourage indoor tanning behavior.

    Perceived health risks from electromagnetic fields in mobile telecommunication and from UV radiation in tanning have become regulation issues in Germany during the last decade. Health risk messages from government expert bodies and the main stakeholders in these areas as well as subsequent consumer protection policy making are investigated. Publications and websites of government expert bodies and the main stakeholders as well as debates in Federal Parliament were analysed to compare argumentation patterns and parliamentary decision-making processes. In both areas, the public received competing health risk messages from the industries and their critics. As a government expert body, the Federal Office for Radiation Protection (BfS) held the view that alleged health risks from electromagnetic telecommunication were not proven, and propagated the precautionary principle. This opinion did not endanger the agreement of 2001 between the government and mobile telecommunication operators. After the failure to obtain voluntary commitment from the tanning industry, by contrast, the BfS recommended stricter consumer protection legislation, which was subsequently implemented. The BfS was in a key position to demand the prerogative of interpretation concerning mutually excluding health risk messages and to provide the argumentation which led the way to non-ionic radiation health protection measures.

    Tyrosine hydroxylase (TH), the initial enzyme in the melanin pathway, catalyzes tyrosine conversion into Dopa. Although expression and regulation of TH have been shown to affect cuticle pigmentation in insects, no direct functional studies to date have focused on the specific physiological processes involving the enzyme during mosquito development. In the current study, silencing of AsTH during the time period of continuous high expression in Anopheles sinensis pupae led to significant impairment of cuticle tanning and thickness, imposing a severe obstacle to eclosion in adults. Meanwhile, deficiency of melanin in interference individuals led to suppression of melanization, compared to control individuals. Consequently, the ability to defend exogenous microorganisms declined sharply. Accompanying down-regulation of the basal expression of five antimicrobial peptide genes resulted in further significant weakening of immunity. TH homologs as well as the composition of upstream transcription factor binding sites at the pupal stage are highly conserved in the Anopheles genus, implying that the TH-mediated functions are crucial in Anopheles. The collective evidence strongly suggests that TH is essential for Anopheles pupae tanning and immunity and provides a reference for further studies to validate the utility of the key genes involved in the melanization pathway in controlling mosquito development.

    This paper presents a method to generate forest/non- forest maps from TanDEM-X interferometric SAR data. Among the several contributions which may affect the quality of interferometric products, the coherence loss caused by volume scattering represents the contribution which is predominantly affected by the presence of vegetation, and is therefore here exploited as main indicator for forest classification. Due to the strong dependency of the considered InSAR quantity on the geometric acquisition configuration, namely the incidence angle and the interferometric baseline, a multi-fuzzy clustering classification approach is used. Some examples are provided which show the potential of the proposed method. Further, additional features such as urban settlements, water, and critical areas affected by geometrical distortions (e.g. shadow and layover) need to be extracted, and possible approaches are presented as well. Very promising results are shown, which demonstrate the potentials of TanDEM-X bistatic data not only for forest identification, but, more in general, for the generation of a global land classification map as a next step.

    Visual images increase attention, comprehension, and recall of health information and influence health behaviors. Health communication campaigns on skin cancer and tanning often use visual images, but little is known about how such images are selected or evaluated. A systematic review of peer-reviewed, published literature on skin cancer and tanning was conducted to determine (a) what visual communication theories were used, (b) how visual images were evaluated, and (c) how visual images were used in the research studies. Seven databases were searched (PubMed/MEDLINE, EMBASE, PsycINFO, Sociological Abstracts, Social Sciences Full Text, ERIC, and ABI/INFORM) resulting in 5,330 citations. Of those, 47 met the inclusion criteria. Only one study specifically identified a visual communication theory guiding the research. No standard instruments for assessing visual images were reported. Most studies lacked, to varying degrees, comprehensive image description, image pretesting, full reporting of image source details, adequate explanation of image selection or development, and example images. The results highlight the need for greater theoretical and methodological attention to visual images in health communication research in the future. To this end, the authors propose a working definition of visual health communication.

    This report presents the results of the design, construction, and test of a plastic film heat exchanger for recovering heat from the liquid effluent waste stream from an animal hide tanning operation. This work is the third phase of a program to evaluate the use of plastic film heat exchangers for energy recovery from low temperature industrial commercial waste streams and processes. The effluent stream from a tanning operation is a corrosive liquid containing pieces of leather, animal fats, and various particulates. The test results from the field unit tests over a period of about five months demonstrated that the plastic films would handle this difficult waste stream satisfactorily, the plastic film would wet satisfactorily and could easily be cleaned of deposits by water sprays, and could achieve values close to the expected thermal heat transfer performance. Although there are practical equipment problems to solve to successfully handle large quantities of a high solids content waste stream such as tannery effluent, the plastic film heat exchanger elements will successfully work in this environment. The plastic films will perform even better for clean corrosive waste streams. 22 figs., 2 tabs.

    Chromium plating used for functional purposes provides an extremely hard, wear and corrosion resistant layer by means of electrolytic deposition. Typical layer thicknesses range between 2.5 and 500 μm. Chromium electroplating baths contain high concentrations of Cr(VI) with chromium trioxide (CrO(3)) as the chromium source. When because of technical or economic reasons a bath gets exhausted, a waste containing mainly chromium as dichromate as well as other heavy metals is generated. Chromium may then be purified for use in other industrial processes with different requirements. In this work, a sustainable system for using galvanic wastes as reagents in the leather tanning industry, thus reducing quantity of wastes to be treated, is presented. Metal cations present in the chromium exhausted bath were precipitated with NaOH. Then, the solution containing mainly soluble Cr(VI) was separated. By means of sodium sulphite in acidic conditions, Cr(VI) was reduced to Cr(III) as chromium (III) sulphate. From chromium (III) sulphate a basic Cr(III) sulphate may be obtained, which is one of most used compounds in the tanning industry. Cr(III) concentration in the final solution allows its reuse without concentration, but with a slight dilution.

    Dermatologists see many patients interested in improving their physical appearance through cosmetic procedures or medical means. Dermatologists frequently counsel patients on sun protection as well, particularly those with a personal or family history of skin cancer, sun-sensitive dermatoses or those with obvious sun damage. Our objective in this study was to identify novel markers of skin cancer risk, which may aid dermatologists in targeting extra sun protection counseling for certain groups. A 16-question survey was distributed to subjects 19 years of age and older in public areas of downtown Birmingham, Alabama in August and September of 2008. Overall, about 40% of both genders reported that they were highly concerned that current sun exposure could cause skin cancer. Participants interested in at least one appearance-related questionnaire item were significantly more likely than those not interested to rate tanned skin as highly important (31.6%vs. 17.5%, P<0.001), and to report regret for previous sun exposure (12.5%vs. 3.6%, P<0.001). Subjects who thought tanned skin was important were significantly more likely to report interest in improving their appearance through cosmetic procedures and medical means. We conclude that individuals with an interest in improving their physical appearance through cosmetic procedures or medical means may be especially in need of sun protection counseling.

    2010-07-16

    This review includes for the first time a dynamical systems analysis of human quadrupedalism in Uner Tan syndrome, which is characterized by habitual quadrupedalism, impaired intelligence, and rudimentary speech. The first family was discovered in a small village near Iskenderun, and families were later found in Adana and two other small villages near Gaziantep and Canakkale. In all the affected individuals dynamic balance was impaired during upright walking, and they habitually preferred walking on all four extremities. MRI scans showed inferior cerebellovermian hypoplasia with slightly simplified cerebral gyri in three of the families, but appeared normal in the fourth. PET scans showed a decreased glucose metabolic activity in the cerebellum, vermis and, to a lesser extent the cerebral cortex, except for one patient, whose MRI scan also appeared to be normal. All four families had consanguineous marriages in their pedigrees, suggesting autosomal recessive transmission. The syndrome was genetically heterogeneous. Since the initial discoveries more cases have been found, and these exhibit facultative quadrupedal locomotion, and in one case, late childhood onset. It has been suggested that the human quadrupedalism may, at least, be a phenotypic example of reverse evolution. From the viewpoint of dynamic systems theory, it was concluded there may not be a single factor that predetermines human quadrupedalism in Uner Tan syndrome, but that it may involve self-organization, brain plasticity, and rewiring, from the many decentralized and local interactions among neuronal, genetic, and environmental subsystems.

    "Uner Tan Syndrome" was further studied in a second family. There was no cerebellar atrophy, except a mild vermial atrophy in MRI scans of the affected individuals. This is not, however, the pathogenesis of the "Uner Tan Syndrome", since in the first and second families there were bipedal men exhibiting very similar MRI scans. The second family may also be considered a live model for reverse evolution in human beings. The present work provided evidence for a reverse evolution: (i) quadrupedality; (ii) primitive mental abilities including language; (iii) curved fingers during wrist-walking of the quadrupedal woman; (iv) arm to leg ratios being close to those of the human-like apes. The quadrupedal individuals were raised in separate places, so that they could not imitate each other, excluding the socio-cultural factors contributing to the habitual quadrupedal gait. The results are consistent with the single gene theory, suggesting a single gene controlling multiple behavioral traits, and the psychomotor theory, and a co-evolution of the human mind, an emergent property of the motor system expressed by human language.

    This paper presents the first results of the developed approach for classifying Greenland ice sheet snow facies, based on the use of interferometric TanDEM-X SAR data. Large-scale mosaics of radar backscatter and volume decorrelation, derived from the interferometric coherence, are used as input data set for applying a classification algorithm based on the c-means fuzzy clustering. The unique data set provided by TanDEM-X is particularly suitable for this analysis due to the single-pass bistatic acquisition mode which does not suffer from temporal decorrelation. The obtained results have been verified with external snow melt data. Moreover, independent multi-temporal TanDEM-X backscatter data and interferometric time series have been analyzed as well.

    Bursicon is a heterodimeric neurohormone that acts through a G protein-coupled receptor named rickets (rk), thus inducing an increase in cAMP and the activation of tyrosine hydroxylase, the rate-limiting enzyme in the cuticular tanning pathway. In insects, the role of bursicon in the post-ecdysial tanning of the adult cuticle and wing expansion is well characterized. Here we investigated the roles of the genes encoding the bursicon subunits during the adult cuticle development in the honeybee, Apis mellifera. RNAi-mediated knockdown of AmBurs α and AmBurs β bursicon genes prevented the complete formation and tanning (melanization/sclerotization) of the adult cuticle. A thinner, much less tanned cuticle was produced, and ecdysis toward adult stage was impaired. Consistent with these results, the knockdown of bursicon transcripts also interfered in the expression of genes encoding its receptor, AmRk, structural cuticular proteins, and enzymes in the melanization/sclerotization pathway, thus evidencing roles for bursicon in adult cuticle formation and tanning. Moreover, the expression of AmBurs α, AmBurs β and AmRk is contingent on the declining ecdysteroid titer that triggers the onset of adult cuticle synthesis and deposition. The search for transcripts of AmBurs α, AmBurs β and candidate targets in RNA-seq libraries prepared with brains and integuments strengthened our data on transcript quantification through RT-qPCR. Together, our results support our premise that bursicon has roles in adult cuticle formation and tanning, and are in agreement with other recent studies pointing for roles during the pharate-adult stage, in addition to the classical post-ecdysial ones.

    Basal cell carcinoma (BCC) incidence is increasing, particularly in young people, and can be associated with significant morbidity and treatment costs. To identify young individuals at risk of BCC, we assessed existing melanoma or overall skin cancer risk prediction models and built a novel risk prediction model, with a focus on indoor tanning and the melanocortin 1 receptor gene, MC1R. We evaluated logistic regression models among 759 non-Hispanic whites from a case-control study of patients seen between 2006 and 2010 in New Haven, Connecticut. In our data, the adjusted area under the receiver operating characteristic curve (AUC) for a model by Han et al. (Int J Cancer. 2006;119(8):1976-1984) with 7 MC1R variants was 0.72 (95% confidence interval (CI): 0.66, 0.78), while that by Smith et al. (J Clin Oncol. 2012;30(15 suppl):8574) with MC1R and indoor tanning had an AUC of 0.69 (95% CI: 0.63, 0.75). Our base model had greater predictive ability than existing models and was significantly improved when we added ever-indoor tanning, burns from indoor tanning, and MC1R (AUC = 0.77, 95% CI: 0.74, 0.81). Our early-onset BCC risk prediction model incorporating MC1R and indoor tanning extends the work of other skin cancer risk prediction models, emphasizes the value of both genotype and indoor tanning in skin cancer risk prediction in young people, and should be validated with an independent cohort.

    ES cells provide a promising tool for the generation of transgenic animals with site-directed mutations. When ES cells colonize germ cells in chimeras, transgenic animals with modified phenotypes are generated and used either for functional genomics studies or for improving productivity in commercial settings. Although the ES cell approach has been limited to mice, there is strong interest for developing the technology in fish. We describe the step-by-step procedure for developing ES cells in fish. Key aspects include avoiding cell differentiation, specific in vitro traits of pluripotency, and, most importantly, testing for production of chimeric animals as the main evidence of pluripotency. The entire process focuses on two model species, zebrafish and medaka, in which most work has been done. The achievements attained in these species, as well as their applicability to other commercial fish, are discussed. Because of the difficulties relating to germ line competence, mostly of long-term fish ES cells, alternative cell-based approaches such as primordial germ cells and nuclear transfer need to be considered. Although progress to date has been slow, there are promising achievements in homologous recombination and alternative avenues yet to be explored that can bring ES technology in fish to fruition.

    Anther culture is a biotechnological method that allows to obtain, in one step, homozygous plants, very important to plant breeding, due to their numerous applications in mutation research, selection, genome sequencing, genetic analysis, and transformation. To induce the microspores, i.e., the immature male gametes, to switch from the normal gametophytic pathway to the sporophytic one, it is necessary to submit them to a type of stress, such as high or low temperature, starvation, or magnetic field. Stress can be applied to the donor plants and/or the floral buds or the anthers or the isolated microspores, before or during the culture. In this chapter, the protocol to induce gametic embryogenesis from anther culture of several cultivars of Citrus clementina Hort. ex Tan. is reported.

    Mapping of forest coverage and forest changes became an increasing issue due to deforestation and forest degradation. Moreover, the estimation of related indicators such as carbon reduction, biomass and wood capacity is of large interest for industry and politics. As forest height is an important contributing parameter for these indicators, the region-wide estimation of forest heights is an essential step. This article investigates the accuracy potential of forest height estimation that can be reached by the current configuration of the two SAR satellites TerraSAR-X and TanDEM-X. Depending on the chosen acquisition mode and flight geometry, products of different quality can be achieved. Eight InSAR data sets showing different characteristics in geometric resolution, length of baseline, and mapping time, are processed and analyzed. To enable a thorough evaluation of the estimated heights, first-pulse LIDAR point clouds and aerial ortho-images are used as reference data.

    Vaccinia Tian Tan (VTT) was used as a vaccine against smallpox in China for millions of people before 1980, yet the biological characteristics of the virus remain unclear. We have characterized VTT with respect to its host cell range, growth properties in vitro, and virulence in vivo. We found that 11 of the 12 mammalian cell lines studied are permissive to VTT infection whereas one, CHO-K1, is non-permissive. Using electron microscopy and sequence analysis, we found that the restriction of VTT replication in CHO-K1 is at a step before viral maturation probably due to the loss of the V025 gene. Moreover, VTT is significantly less virulent than vaccinia WR but remains neurovirulent in mice and causes significant body weight loss after intranasal inoculation. Our data demonstrate the need for further attenuation of VTT to serve either as a safer smallpox vaccine or as a live vaccine vector for other pathogens.

    Bivachny Glacier, a tributary of the more than 70 km long Fedchenko Glacier in the Pamir Mountains, Central Asia, is a surge-type glacier with three known surges during the 20th century. In 2011, the most recent surge started which, in contrast to the previous ones, evolved down the whole glacier and reached the confluence with Fedchenko Glacier. Spatial and temporal glacier volume changes can be derived from high-resolution digital elevation models (DEMs) based on bistatic InSAR data from the TanDEM-X mission. There are nine DEMs available between 2011 and 2015 covering the entire surge period in time steps from few months up to one year. During the surge, the glacier surface elevation increased by up to 130 m in the lower part of the glacier; and change rates of up to 0.6 m per day were observed. The surface height dataset was complemented with glacier surface velocity information from TerraSAR-X/ TanDEM-X data as well as optical Landsat imagery. While the glacier was practically stagnant in 2000 after the end of the previous surge in the 1990s, the velocity increase started in 2011 in the upper reaches of the ablation area and successively moved downwards and intensified, reaching up to 4.0 m per day. The combination of surface elevation changes and glacier velocities, both of high temporal and spatial resolution, provides the unique opportunity to describe and analyse the evolution of the surge in unprecedented detail. Especially the relation between the mobilization front and the local mass transport provides insight into the surge dynamics.

    Lithographic patterning at the 7 and 5 nm nodes will likely require EUV (λ=13.5 nm) lithography for many of the critical levels. All optical elements in an EUV scanner are reflective which requires the EUV photomask to be illuminated at an angle to its normal. Current scanners have an incidence of 6 degree, but future designs will be <6 degrees for high-NA systems. Non-telecentricity has been shown to cause H-V bias due to shadowing, pattern shift through focus, and image contrast lost due to apodization by the reflective mask coating. A thinner EUV absorber can dramatically reduce these issues. Ni offers better EUV absorption than Ta-based materials, which hold promise as a thinner absorber candidate. Unfortunately, the challenge of etching Ni has prevented its adoption into manufacturing. We propose a new absorber material that infuses Ni nanoparticles into the TaN host medium, allowing for the use of established Ta etching chemistry. A thinner is absorber is created due to the enhanced absorption properties of the Ni-Ta nano-composite material. Finite integral method and effective medium theory-based transfer matrix method have been independently developed to analyze the performance of the nano-composite absorption layer. We show that inserting 15% volume fraction Ni nanoparticles into 40-nm of TaN absorber material can reduce the reflection below 2% over the EUV range. Numerical simulations confirm that the reduced reflectivity is due to the increased absorption of Ni, while scattering only contributes to approximately 0.2% of the reduction in reflectivity.

  15. Urban DEM generation, analysis and enhancements using TanDEM-X

    2013-11-01

    This paper analyzes the potential of the TanDEM-X mission for the generation of urban Digital Elevation Models (DEMs). The high resolution of the sensors and the absence of temporal decorrelation are exploited. The interferometric chain and the problems encountered for correct mapping of urban areas are analyzed first. The operational Integrated TanDEM-X Processor (ITP) algorithms are taken as reference. The ITP main product is called the raw DEM. Whereas the ITP coregistration stage is demonstrated to be robust enough, large improvements in the raw DEM such as fewer percentages of phase unwrapping errors, can be obtained by using adaptive fringe filters instead of the conventional ones in the interferogram generation stage. The shape of the raw DEM in the layover area is also shown and determined to be regular for buildings with vertical walls. Generally, in the presence of layover, the raw DEM exhibits a height ramp, resulting in a height underestimation for the affected structure. Examples provided confirm the theoretical background. The focus is centered on high resolution DEMs produced using spotlight acquisitions. In particular, a raw DEM over Berlin (Germany) with a 2.5 m raster is generated and validated. For this purpose, ITP is modified in its interferogram generation stage by adopting the Intensity Driven Adaptive Neighbourhood (IDAN) algorithm. The height Root Mean Square Error (RMSE) between the raw DEM and a reference is about 8 m for the two classes defining the urban DEM: structures and non-structures. The result can be further improved for the structure class using a DEM generated with Persistent Scatterer Interferometry. A DEM fusion is thus proposed and a drop of about 20% in the RMSE is reported.

  16. Exploring the Potential of TanDEM-X Data in Rice Monitoring

    2015-12-01

    In this work, phenological parameters such as growth stage, calendar estimation, crop density and yield estimation for rice fields are estimated employing TanDEM-X data. Currently, crop monitoring is country-dependent. Most countries have databases based on cadastral information and annual farmer inputs. Inaccuracies are coming from wrong or missing farmer declarations and/or coarsely updated cadastral boundary definitions. This leads to inefficient regulation of the market, frauds as well as to ecological risks. An accurate crop calendar is also missing, since farmers provide estimations in advance and there is no efficient way to know the growth status over large plantations. SAR data is of particular interest for these purposes. The proposed method includes two step approach including field detection and phenological state estimation. In the context of precise farming it is substantial to define field borders which are usually changing every cultivation period. Linking the SAR inherit properties to transplanting practice such as irrigation, the spatial database of rice-planted agricultural crops can be updated. Boundaries of agricultural fields will be defined in the database, and assignments of crops and sowing dates will be continuously updated by our monitoring system considering that sowing practice variously changes depending on the field owner decision. To define and segment rice crops, the system will make use of the fact that rice fields are characterized as flooded parcels separated by path networks composed by soil or rare grass. This natural segmentation is well detectable by inspecting low amplitude and coherence values of bistatic acquisitions. Once the field borders are defined, the phenology estimation of crops monitored at any time is the key point of monitoring. In this aspect the wavelength and the polarization option of TanDEM-X are enough to characterize the small phenological changes. The combination of bistatic interferometry and Radiative

    To determine the influence of seismogenic disturbances on the calm state of the iono-sphere and assess the impact of turbulence development in sporadic-E during earthquake prepa-ration period we calculated the variation in the range of semitransparency ∆fES = f0ES - fbES. The study was based primarily on the ionograms obtained by vertical sounding of the ionosphere at Dushanbe at nighttime station from 15 to 29 August 1986. In this time period four successive earthquakes took place, which serves the purpose of this study of the impact of seis-mogenic processes on the intensity of the continuous generation of ionospheric turbulence. Analysis of the results obtained for seismic-ionospheric effects of 1986 earthquakes at station Dushanbe has shown that disturbance of ionospheric parameters during earthquake prepa-ration period displays a pronounced maximum with a duration of t = 1-6 hours. Ionospheric effects associated with the processes of earthquake preparation emerge quite predictably, which verifies seismogenic disturbances in the ionosphere. During the preparation of strong earthquakes, ionograms of vertical sounding produced at station Dushanbe - near the epicenter area - often shown the phenomenon of spreading traces of sporadic Es. It is assumed that the duration of manifestation of seismic ionospheric precursors in Du-shanbe τ = 1 - 6 hours may be associated with deformation processes in the Earth's crust and var-ious faults, as well as dissimilar properties of the environment of the epicentral area. It has been shown that for earthquakes with 4.5 ≤ M ≤ 5.5 1-2 days prior to the event iono-spheric perturbations in the parameters of the sporadic layer Es and an increase in the value of the range of semitransparency Es - ΔfEs were observed, which could lead to turbulence at altitudes of 100-130 km.

    On 21 June 2010 the TerraSAR-X satellite was joined by the TanDEM-X satellite. A Global Positioning System (GPS) radio occultation (RO) experiment using the twin satellites has been carried out to estimate the precision of GPS atmospheric soundings. For the Day Of Year (DOY) 330-336, 2011, we analyze phase and amplitude data recorded by GPS receivers separated by a few hundred meters in a low earth orbit and derive collocated atmospheric refractivity profiles. In the altitude range 10-20 km the standard deviation between TerraSAR-X and TanDEM-X refractivity does not exceed 0.15%. The standard deviation is rapidly increasing for lower and higher altitudes; close to the surface and at an altitude of 30 km the standard deviation reaches 0.8% and 0.5%, respectively. Systematic deviations between TerraSAR-X and TanDEM-X refractivity in the considered altitude range (0-30 km) are negligible. The results confirm the anticipated high precision of the GPS RO technique. However, the difference in the retrieved refractivity in the lower troposphere for different Open Loop (OL) signal tracking parameters, altered onboard TanDEM-X for DOY 49-55, 2012, calls for an in depth analysis. At the moment we can not exclude that a potential bias in the OL Doppler model introduces a bias in our retrieved refractivity at altitudes <8 km.

    Water scarcity in the dry season is a vital problem in dryland regions such as northeastern Brazil. Water supplies in these areas often come from numerous reservoirs of various sizes. However, inventory data for these reservoirs is often limited due to the expense and time required for their acquisition via field surveys, particularly in remote areas. Remote sensing techniques provide a valuable alternative to conventional reservoir bathymetric surveys for water resource management. In this study single pass TanDEM-X data acquired in bistatic mode were used to generate digital elevation models (DEMs) in the Madalena catchment, northeastern Brazil. Validation with differential global positioning system (DGPS) data from field measurements indicated an absolute elevation accuracy of approximately 1m for the TanDEM-X derived DEMs (TDX DEMs). The DEMs derived from TanDEM-X data acquired at low water levels show significant advantages over bathymetric maps derived from field survey, particularly with regard to coverage, evenly distributed measurements and replication of reservoir shape. Furthermore, by mapping the dry reservoir bottoms with TanDEM-X data, TDX DEMs are free of emergent and submerged macrophytes, independent of water depth (e.g. >10m), water quality and even weather conditions. Thus, the method is superior to other existing bathymetric mapping approaches, particularly for inland water bodies. The proposed approach relies on (nearly) dry reservoir conditions at times of image acquisition and is thus restricted to areas that show considerable water levels variations. However, comparisons between TDX DEM and the bathymetric map derived from field surveys show that the amount of water retained during the dry phase has only marginal impact on the total water volume derivation from TDX DEM. Overall, DEMs generated from bistatic TanDEM-X data acquired in low water periods constitute a useful and efficient data source for deriving reservoir bathymetry and show

    Chromium precipitation from spent tanning liquors using industrial alkaline tailings is described and removal efficiencies are compared with those obtained with traditional chemicals as NaOH, CaO and MgO: (1) using steelmaking dusts at dosages up to 70 g/l residual Cr remains {ge} 3.7 mg/l. Moreover Cr and mainly Pb are partially leached by the spent tanning liquor, therefore limiting the use of this industrial residue as Cr precipitant; (2) a dosage of 80 g/l (dry basis) of chemical sludge from a water treatment plant results in a removal efficiency of 99.97% Cr and residual Cr {le} 2 mg/l under experimental conditions that include stirring at 100 rpm for 1 h and settling for 23 h. Sedimentation time may be reduced to 2 h if stirring is extended to 2 h. Resulting sludge volume is about 400 ml/l. However, during Cr precipitation, Al is leached form the added product up to about 40 mg Al per liter of supernatant; (3) precipitation using acetylene production sludge only requires a dosage of 16 g/l (dry basis) to remove 99.96% Cr after stirring for 1 h and settling for 2 h. The soluble Cr concentration in the clarified effluent is {le} 2 mg/l and the sludge volume about 500 ml/l. This Cr level can also be achieved at a dosage of 14 g/l, provided the stirring time is increased to 3 h; (4) these results are comparable with those using either CaO or MgO at similar dosages; and (5) NaOH at dosages between 6.4 and 14 g/l proved to be not sufficiently effective for Cr precipitation. Although removal efficiencies up to 99.9% are achieved, residual Cr is always above 8.7 mg/l. Additionally, the resulting sludge is not very dense, thus leading to high sludge volume production.

    On June 21, 2010 the TanDEM-X satellite (TDX) was injected into orbit at 15,700 km distance from its twin satellite TerraSAR-X (TSX), which has been in orbit since 2007. Already one month later TDX acquired a formation with TSX in order to build up the first single-pass radar interferometer in space. Within three years of close formation flying with flexible baselines ranging from 150 m to a few kilometers the twin satellites will collect interferometric radar measurements for the generation of a global digital elevation model with unprecedented accuracy. This paper elaborates on the TDX pre-launch analysis performed in the fields of collision assessment during orbit injection and target formation acquisition. To avoid a critical close approach shortly after TDX separation, the risk of collision between the already flying TSX satellite and the newly injected elements (DNEPR upper-stage, gas dynamic shield, and TDX satellite) had to be carefully analyzed. Further, the paper discusses a fuel-saving formation acquisition strategy, for which the maneuver budget is analyzed as a function of launch day and launch injection accuracy. Finally, flight results are presented to illustrate the successful formation acquisition realized in July 2010 and the formation reconfiguration process from the 20 km wide formation into the 300-400 m close formation performed in October 2010. This reconfiguration marked the start of the bi-static TDX/TSX instrument operation.

    Remote sensing plays a key role in monitoring and assessing environmental changes. Because of its special imaging characteristics such as high-resolution, capabilities to obtain data in all weather conditions and sensitivity to geometrical and dielectric properties of the features, Synthetic Aperture Radar (SAR) technology has become a powerful technique to detect small scale changes related to earth surface.SAR images contain the information of both phase and intensity in different modes like single, dual and full polarimetric states which are important in order to extract information about various targets. In this study we investigate phenological changes in an agricultural region using high-resolution X-band SAR data. The case study is located in Doroud region of Lorestan province, west of Iran. The purpose is to investigate the ability of copolar and interferometric coherence extracted from TanDEM-X dual polarimetry (HH/VV) in bistatic StripMap mode for tracking the phenological changes of crops during growing season. The data include 11 images acquired between 12.06.2012 and 02.11.2012 and 6 images acquired between 30.05.2013 and 04.08.2013 in the CoSSC format. Results show that copolar coherence is almost able to follow phenological changes but interferometric coherence has a near constant behaviour with fluctuations mainly related to baseline variations.

    Pyrolysis is the thermal degradation of organic material in oxygen-free or very lean oxygen atmosphere. This study evaluates the use of pyrolysis for conversion of leather wastes from chromium tanning processes into Carbonized Leather Residues (CLR), and the utilization of CLR in metallurgical processes through the production of iron ore pellets. CLR was used to replace mineral coal in proportions of 10% and 25% on fixed carbon basis content in the mixtures for pellets preparation. Experimental conversions were performed on a pilot scale pyrolysis plant and a pelletizing reactor of the "pot grate" type. The results demonstrated the technical feasibility of using the charcoal product from animal origin as an energy source, with recovery of up to 76.47% of chromium contained in CLR in the final produced of iron ore pellets. Pellets with 25% replacement of fixed carbon in the coal showed an enhanced compressive strength, with an average value of 344kgfpellet(-1), compared to 300kgfpellet(-1) for standard produced pellets.

    Anthracnose caused by Colletotrichum gloeosporioides is one of the most serious postharvest diseases of citrus fruit. Fruit peels infected with C. gloeosporioides and the peels of healthy fruit were analysed for flavonoids, using high performance liquid chromatography-tandem mass spectroscopy, to evaluate variations in flavonoid levels in Citrus benikoji Hort. ex. Tan. Seventeen flavonoids were characterised from the fruit peels. The flavonoids were validated using structurally related standards and quantified. Among the 17 flavonoids, the concentration of component 3 was the highest and that of component 10 was the lowest. During 8 days after inoculation, the concentration of the seven flavonoids 1-3, 5, 6, 13, and 14 increased gradually up to day 8. Flavonoid 4 was detected from day 7. The seven minor flavonoid components, 8-12, 15, and 16 increased to day 5 and then decreased. However, flavonoids level variations were not significantly different from that of the non-infected fruits during the experimental period. The monitoring suggested that the constitutively formed seven polymethoxyflavones (8-12, 15, and 16) may act as phytoanticipins in the defence mechanism against the fungus, and that hespertin 7-O-glucoside (4), produced de novo on day 6 after infection, may function as a phytoalexin.

    Leather artifacts in historical collections and archives are often contaminated by physical changes such as soiling, which alter their appearance and readability, and by chemical changes which occur on aging and give rise to excessive proportion of acids that promote hydrolysis of collagen, eventually leading to gelatinization and loss of mechanical properties. However, both cleaning and pH adjustment of vegetable-tanned leather pose a great challenge for conservators, owing to the sensitivity of these materials to the action of solvents, especially water-based formulations and alkaline chemicals. In this study, the cleaning of historical leather samples was optimized by confining an oil-in-water nanostructured fluid in a highly retentive chemical hydrogel, which allows the controlled release of the cleaning fluid on sensitive surfaces. The chemical gel exhibits optimal viscoelasticity, which facilitates its removal after the application without leaving residues on the object. Nanoparticles of calcium hydroxide and lactate, dispersed in 2-propanol, were used to adjust the pH up to the natural value of leather, preventing too high alkalinity which causes swelling of fibers and denaturation of the collagen. The treated samples were characterized using scanning electron microscopy, controlled environment dynamic mechanical analysis, and infrared spectroscopy. The analytical assessment validated the use of tools derived from colloid and materials science for the preservation of collagen-based artifacts.

    We analyse bistatic HH-polarised TanDEM-X interferometric synthetic aperture radar (InSAR) data acquired over winter, dry snow conditions in a sub- Arctic site in Norway. Exploiting the principles of across-track interferometry, the elevation of the scattering phase centre estimated by the phase difference between the two SAR acquisitions. Interference patterns were assessed both qualitatively and quantitatively. Clearings and forest stands, were analysed. Interferometric phase uncertainty and spatio-temporal consistency were analysed by means of scattering phase centre elevation accuracy and coherence degree, γ with respect to hydro-meteorological conditions. Clearings displayed absolute height errors of < 1 m. The sole approximation was to consider volume decorrelation effects as main source of elevation ambiguities and coherence decay. Principal Component Analysis was conducted to identify the combined influence of variables describing the radar response and scattering centre. However, the derived DEMs attained high vertical accuracy, the sub-meter height errors might relate to snowcover effects. Coherence was strongly influenced by snowpack parameters suggesting TDM coherence inversion may enable snow cover monitoring.

    We present strategies to search for heavy neutral Higgs bosons decaying to top quark pairs, as often occurs at low tan β in type II two Higgs doublet models such as the Higgs sector of the MSSM. The resonant production channel is unsatisfactory due to interference with the SM background. We instead propose to utilize same-sign dilepton signatures arising from the production of heavy Higgs bosons in association with one or two top quarks and subsequent decay to a top pair. We find that for heavier neutral Higgs bosons the production in association with one top quark provides greater sensitivity than production in association with two top quarks. We obtain current limits at the LHC using Run I data at 8 TeV and forecast the sensitivity of a dedicated analysis during Run II at 14 TeV. Then we perform a detailed BDT study for the 14 TeV LHC and a future 100 TeV collider.

    A study was conducted to investigate the sediment health and water quality of the River Sagana, Kenya, as impacted by the local tanning industry. Chemical analysis identified the main chemical pollutants (pentachlorophenols and chromium) while a bioassay addressed pollutant bioavailability. The bioassay, exploiting the luminescence response of a lux marked bacterial biosensor, was coupled to a dehydrogenase and Dapnia magna test to determine toxicity effects on sediments. Results highlighted the toxicity of the tannery effluent to the sediments at the point of discharge (64% of control bioluminescence) with gradual improvement downstream. There was a significant increase in dehydrogenase downstream, with the enzyme activity attaining a peak at 600 m, also indicating a gradual reduction of toxicity. Biological oxygen demand (19.56 mg L(-1)) dissolved oxygen (3.97 mg L(-1)) and high lethal dose value (85%) of D. magna also confirmed an initial stress at the point of discharge and recovery downstream. Optical density of surface water demonstrated an increase in suspended particulates and colour after the discharge point, eventually decreasing beyond 400 m. In conclusion, the study highlighted the importance of understanding the biogeochemistry of river systems impacted by industries discharging effluent into them and the invaluable role of a biosensor-based ecotoxicological approach to address effluent hazards, particularly in relation to river sediments.

    The integrity and dynamic properties of the microtubule cytoskeleton are indispensable for the development of the mammalian brain. Consequently, mutations in the genes that encode the structural component (the α/β-tubulin heterodimer) can give rise to severe, sporadic neurodevelopmental disorders. These are commonly referred to as the tubulinopathies. Here we report the addition of recessive quadrupedalism, also known as Uner Tan syndrome (UTS), to the growing list of diseases caused by tubulin variants. Analysis of a consanguineous UTS family identified a biallelic TUBB2B mutation, resulting in a p.R390Q amino acid substitution. In addition to the identifying quadrupedal locomotion, all three patients showed severe cerebellar hypoplasia. None, however, displayed the basal ganglia malformations typically associated with TUBB2B mutations. Functional analysis of the R390Q substitution revealed that it did not affect the ability of β-tubulin to fold or become assembled into the α/β-heterodimer, nor did it influence the incorporation of mutant-containing heterodimers into microtubule polymers. The 390Q mutation in S. cerevisiae TUB2 did not affect growth under basal conditions, but did result in increased sensitivity to microtubule-depolymerizing drugs, indicative of a mild impact of this mutation on microtubule function. The TUBB2B mutation described here represents an unusual recessive mode of inheritance for missense-mediated tubulinopathies and reinforces the sensitivity of the developing cerebellum to microtubule defects.

    The leather tannery industry produces a significant amount of solid and hazardous wastes. Chromium-containing wastes like tanned shavings used to be incinerated in order to recover energy. The incineration process generates ashes that must be disposed of. This paper is a report on the results of the evaluation of technological properties and environmental compatibility of products made of alumina and ashes from incinerated chrome tanned shavings. The raw materials, tannery ashes and alumina were mixed together in different proportions. The ceramic bodies were molded using a hydraulic press and fired with a heating rate of 100 K/h until 1400 degrees C for 4 h in a muffle furnace. The ceramic specimens were characterized regarding physical, mechanical and thermal properties. Leaching tests, according to Brazilian, German and Dutch regulations, were performed on ceramic bodies containing different additions of ash. Results show that the ceramic materials produced are acceptable for refractory applications.

    Leather processing discharges enormous amount of chrome containing leather solid waste which creates a major disposal problem. Chrome-tanned leather solid waste is a complex of collagen and chromium. The presence of chromium limits protein application in fertilizer industry. The purified protein hydrolysate with zero chromium could be used as a nitrogen source for fertilizer formulation. In this study, an attempt has been made to employ purified protein hydrolysate derived from chrome-tanned leather shavings (CTLS) in formulation of fertilizer. The formulated fertilizer (1–3 t ha(-1)) is employed as nitrogen source in production of soybean. Plant growth study demonstrates that formulated fertilizer dosage 3 t ha(-1) produced similar effects of commercial fertilizer-treated plants. Application of formulated fertilizer yielded higher seed in plant than commercial fertilizer.

  1. Precise Determination of the Baseline Between the TerraSAR-X and TanDEM-X Satellites

    NASA Astrophysics Data System (ADS)

    Koenig, Rolf; Rothacher, Markus; Michalak, Grzegorz; Moon, Yongjin

    TerraSAR-X, launched on June 15, 2007, and TanDEM-X, to be launched in September 2009, both carry the Tracking, Occultation and Ranging (TOR) category A payload instrument package. The TOR consists of a high-precision dual-frequency GPS receiver, called Integrated GPS Occultation Receiver (IGOR), for precise orbit determination and atmospheric sounding and a Laser retro-reflector (LRR) serving as target for the global Satellite Laser Ranging (SLR) ground station network. The TOR is supplied by the GeoForschungsZentrum Potsdam (GFZ) Germany, and the Center for Space Research (CSR), Austin, Texas. The objective of the German/US collaboration is twofold: provision of atmospheric profiles for use in numerical weather predictions and climate studies from the occultation data and precision SAR data processing based on precise orbits and atmospheric products. For the scientific objectives of the TanDEM- X mission, i.e., bi-static SAR together with TerraSAR-X, the dual-frequency GPS receiver is of vital importance for the millimeter level determination of the baseline or distance between the two spacecrafts. The paper discusses the feasibility of generating millimeter baselines by the example of GRACE, where for validation the distance between the two GRACE satellites is directly available from the micrometer-level intersatellite link measurements. The distance of the GRACE satellites is some 200 km, the distance of the TerraSAR-X/TanDEM-X formation will be some 200 meters. Therefore the proposed approach is then subject to a simulation of the foreseen TerraSAR-X/TanDEM-X formation. The effect of varying space environmental conditions, of possible phase center variations, multi path, and of varying center of mass of the spacecrafts are evaluated and discussed.

    Objectives To describe Scottish adolescents’ sun-related behaviours and tanning attitudes and assess associations with skin cancer awareness. Design Cross-sectional study. Setting 20 state secondary schools in one Scottish local authority (Glasgow City). Participants 2173 adolescents (females: 50.7%, n=1102) with a mean age of 12.4 (SD=0.55). Outcome measures Sun-related behaviour (suntan, sunbathing, sunburn, sunscreen use, sunbed use), tanning attitudes, skin cancer-related symptom and risk factor awareness. Results Adolescents reported poor sun-related practice: 51% of adolescents reported sunburn the previous summer of whom 38% indicated sunburn on more than one occasion. Skin cancer awareness was low: 45% recognised ‘change in the appearance of a mole’ as a cancer symptom, and 39% agreed that ‘getting sunburnt more than once as a child’ increased cancer risk. 42% and 26% of adolescents, respectively, reported that friends and family held protanning attitudes. Compared with males, females were statistically significantly more likely to: report sunbathing (p<0.001), use of lotions or oil to aid tanning (p=0.009) and sunburn (p<0.001); know that changes in the appearance of a mole was a skin cancer symptom (p=0.036) and sunburn more than once as a child was a skin cancer risk factor (p=0.005); perceive their friends to hold protanning attitudes (p<0.001) and indicate that a tan made them feel better about themselves (p<0.001), more attractive to others (p=0.011) and healthier (p<0.001). Conclusions Scottish adolescents had poor sun protection practice and low skin cancer awareness. Girls adopted riskier sun-related behaviour despite greater awareness of skin cancer-related risk. Urgent action is required to promote positive sun-related behaviour and increase skin cancer awareness among Scottish adolescents. However, further research is needed to inform the development of effective sun-safe interventions. PMID:24793258

    Selectivity of etching between physical vapor-deposited TiN and TaN was studied in chlorine-containing plasmas, under isotropic etching conditions. Etching rates for blanket films were measured in-situ using optical emission of the N{sub 2} (C{sup 3}{Pi}{sub u}{yields}B{sup 3}{Pi}{sub g}) bandhead at 337 nm to determine the etching time, and transmission electron microscopy to determine the starting film thickness. The etching selectivity in Cl{sub 2}/He or HCl/He plasmas was poor (<2:1). There was a window of very high selectivity of etching TiN over TaN by adding small amounts (<1%) of O{sub 2} in the Cl{sub 2}/He plasma. Reverse selectivity (10:1 of TaN etching over TiN) was observed when adding small amounts of O{sub 2} to the HCl/He plasma. Results are explained on the basis of the volatility of plausible reaction products.

    In the past few years, the cellular effects of ultraviolet (UV) irradiation induced in skin have become increasingly recognized. Indeed, it is now well known that UV irradiation induces structural and cellular changes in all the compartments of skin tissue. The generation of reactive oxygen species (ROS) is the first and immediate consequence of UV exposure and therefore the quantitative determination of free radical reactions in the skin during UV radiation is of primary importance for the understanding of dermatological photodamage. The RSF method (radical sun protection factor) herein presented, based on electron spin resonance spectroscopy (ESR), enables the measurement of free radical reactions in skin biopsies directly during UV radiation. The amount of free radicals varies with UV doses and can be standardized by varying UV irradiance or exposure time. The RSF method allows the determination of the protective effect of UV filters and sunscreens as well as the radical induction capacity of self-tanning agents as dihydroxyacetone (DHA). The reaction of the reducing sugars used in self-tanning products and amino acids in the skin layer (Maillard reaction) leads to the formation of Amadori products that generate free radicals during UV irradiation. Using the RSF method three different self-tanning agents were analyzed and it was found, that in DHA-treated skin more than 180% additional radicals were generated during sun exposure with respect to untreated skin. For this reason the exposure duration in the sun must be shortened when self-tanners are used and photoaging processes are accelerated.

    The objective of the present study was to determine the effectiveness of biogas production during methane fermentation of wastewaters originating from the dairy, tanning and sugar industries, by means ofrespirometric measurements conducted at a temperature of 35 degrees C. Experiments were carried out with the use of model tanks of volume 0.5 dm3. A high production yield of biogas, with methane content exceeding 60%, was achieved in the case of the anaerobic treatment of wastewaters from the dairy and sugar industries. A significantly lower effect was observed in the case of tanning wastewaters. The effectiveness of the fermentation process decreased with increasing loading of the tanks with a feedstock of organic compounds. By loading a model tank with this feedstock, the effectiveness of treatment ranged from 62.8% to 71.4% residual chemical oxygen demand for dairy wastewaters and from 57.9% to 64.1% for sugar industry wastewaters. The efficiency of organic compound removal from tanning wastewaters was below 50%, regardless of the method applied.

    The nucleus is positioned toward the rear of most migratory cells. In fibroblasts and myoblasts polarizing for migration, retrograde actin flow moves the nucleus rearward, resulting in the orientation of the centrosome in the direction of migration. In this study, we report that the nuclear envelope-localized AAA+ (ATPase associated with various cellular activities) torsinA (TA) and its activator, the inner nuclear membrane protein lamina-associated polypeptide 1 (LAP1), are required for rearward nuclear movement during centrosome orientation in migrating fibroblasts. Both TA and LAP1 contributed to the assembly of transmembrane actin-associated nuclear (TAN) lines, which couple the nucleus to dorsal perinuclear actin cables undergoing retrograde flow. In addition, TA localized to TAN lines and was necessary for the proper mobility of EGFP-mini-nesprin-2G, a functional TAN line reporter construct, within the nuclear envelope. Furthermore, TA and LAP1 were indispensable for the retrograde flow of dorsal perinuclear actin cables, supporting the recently proposed function for the nucleus in spatially organizing actin flow and cytoplasmic polarity. Collectively, these results identify TA as a key regulator of actin-dependent rearward nuclear movement during centrosome orientation.

    Mutually conflicting results have been presented in earlier studies on the long-term relation of geomagnetic activity (GA) and the winter northern annular mode (NAM) and its modulation by quasi-biennial oscillation (QBO). Some studies have found a stronger positive relation in the easterly phase of the QBO, while in other studies a stronger positive relation was found in the westerly phase of the QBO. Using QBO reconstruction from the beginning of the twentieth century we find that the QBO modulation of the GA-NAM relation is temporally variable, which explains the earlier, seemingly differing results. Positive relation is found to be valid in the easterly QBO phase at 30 hPa for the whole twentieth century. We also find that the QBO at 30 hPa better represents the Holton-Tan relation for the surface circulation and that the Holton-Tan relation is only observed during early/mid winter, while an anti-Holton-Tan relation is found in the late winter for strong geomagnetic activity. These results emphasize the systematic response of NAM to particle precipitation during the entire twentieth century and underline the importance of considering the preconditioning of the atmosphere when studying the solar-related effects upon climate.

    First principles calculations have been carried out to study the native single-defects and multi-vacancies in TaN and TiN with a cubic rocksalt structure mainly used as diffusion barriers. Our results indicate that vacancies are the most stable single-defects in both compounds and that nitrogen interstitial defects in tetrahedral interstitial site are significantly more stable in TaN than in TiN. The interactions between vacancies are attractive in TaN in contrast to the case of TiN. The vacancies show a much larger tendency to cluster and to form bi- and tri- vacancies in TaN than in TiN. We suggest that the number of d electrons might explain this difference in the defect stability. These results will have impact on the use of these materials as diffusion barrier.

  10. TanDEM-X high resolution DEMs and their applications to flow modeling

    NASA Astrophysics Data System (ADS)

    Wooten, Kelly M.

    Lava flow modeling can be a powerful tool in hazard assessments; however, the ability to produce accurate models is usually limited by a lack of high resolution, up-to-date Digital Elevation Models (DEMs). This is especially obvious in places such as Kilauea Volcano (Hawaii), where active lava flows frequently alter the terrain. In this study, we use a new technique to create high resolution DEMs on Kilauea using synthetic aperture radar (SAR) data from the TanDEM-X (TDX) satellite. We convert raw TDX SAR data into a geocoded DEM using GAMMA software [Werner et al., 2000]. This process can be completed in several hours and permits creation of updated DEMs as soon as new TDX data are available. To test the DEMs, we use the Harris and Rowland [2001] FLOWGO lava flow model combined with the Favalli et al. [2005] DOWNFLOW model to simulate the 3-15 August 2011 eruption on Kilauea's East Rift Zone. Results were compared with simulations using the older, lower resolution 2000 SRTM DEM of Hawaii. Effusion rates used in the model are derived from MODIS thermal infrared satellite imagery. FLOWGO simulations using the TDX DEM produced a single flow line that matched the August 2011 flow almost perfectly, but could not recreate the entire flow field due to the relatively high DEM noise level. The issues with short model flow lengths can be resolved by filtering noise from the DEM. Model simulations using the outdated SRTM DEM produced a flow field that followed a different trajectory to that observed. Numerous lava flows have been emplaced at Kilauea since the creation of the SRTM DEM, leading the model to project flow lines in areas that have since been covered by fresh lava flows. These results show that DEMs can quickly become outdated on active volcanoes, but our new technique offers the potential to produce accurate, updated DEMs for modeling lava flow hazards.

    Sunless tanning with dihydroxyacetone (DHA) is not considered to be a sunscreen although it does absorb parts of the ultraviolet (UV) spectrum. We investigated the protection with topical application of DHA against solar UV-induced skin carcinogenesis in lightly pigmented hairless hr/hr C3H/Tif mice. Broad-spectrum UV radiation, simulating the UV part of the solar spectrum was obtained from one Philips TL12 and five Bellarium-S SA-1-12 tubes. Three groups of mice were UV-exposed four times a week to a dose-equivalent of four times the standard erythema dose (SED), without or with application of 5 or 20% DHA only twice a week. Similarly, three groups of mice were treated with DHA and irradiated with a high UV dose (8 SED), simulating a skin burn. Two groups (controls) were not irradiated, but either left untreated or treated with 20% DHA alone. The UV-induced skin pigmentation by melanogenesis could easily be distinguished from DHA-induced browning and was measured by a non-invasive, semi-quantitative method. Application of 20% DHA reduced by 63% the pigmentation produced by 4 SED, however, only by 28% the pigmentation produced by 8 SED. Furthermore, topical application of 20% DHA significantly delayed the time to appearance of the first tumor >or=1mm (P=0.0012) and the time to appearance of the third tumor (P=2 x 10(-6)) in mice irradiated with 4 SED. However, 20% DHA did not delay tumor development in mice irradiated with 8 SED. Application of 5% DHA did not influence pigmentation or photocarcinogenesis. In conclusion, this is the first study to show that the superficial skin coloring generated by frequent topical application of DHA in high concentrations may delay skin cancer development in hairless mice irradiated with moderate UV doses.

    Experimental study of the in vivo kinetics of tanning in human skin has been limited by the difficulties in measuring changes in melanin pigmentation independent of the ultravioletinduced changes in erythema. The present study attempted to experimentally circumvent this issue. We have studied erythemal and tanning responses following a single exposure to a range of doses of ultraviolet B irradiation on the buttock and the lower back in 98 subjects. Erythema was assessed using reflectance techniques at 24 h and tanning measured as the L* spectrophotometric score at 7 days following noradrenaline iontophoresis. We show that dose (P < 0.0001), body site (P < 0.0001), skin colour (P < 0.0001), ancestry (P = 0.0074), phototype (P = 0.0019) and sex (P = 0.04) are all independent predictors of erythema. Quantitative estimates of the effects of these variables are reported, but the effects of ancestry and phototype do not appear solely explainable in terms of L* score. Dose (P < 0.0001), body site (P < 0.0001) and skin colour (P = 0.0365) or, as an alternative to skin colour, skin type (P = 0.0193) predict tanning, with those with lighter skin tanning slightly more to a defined UVB dose. If erythema is factored into the regression, then only dose and body site remain significant predictors of tanning: therefore neither phototype nor pigmentary factors, such as baseline skin colour, or eye or hair colour, predict change in skin colour to a unit erythemal response.

    Reverse oblique intertrochanteric fractures have unique mechanical characteristics and are often treated with intramedullary implants. We compared the outcomes of the reconstruction trochanteric antegrade nail (TAN) with the proximal femoral nail antirotation (PFNA). Between July 2008 and February 2014, we reviewed all patients with reverse oblique intertrochanteric fractures treated at our hospital. Patients with pathological fractures and those who were treated with other than TAN and PFNA nailing systems were excluded. Preoperative assessment included the Abbreviated mental test score (AMT), the ASA grade, pre-injury mobility and place of residence. Postoperative outcome measures included the type of implant used, time to fracture union, failures of fixation and revision surgeries. Fifty-eight patients were included and divided into two groups based on the treatment: 22 patients treated with TAN and 36 patients treated with PFNA systems. The two groups were well matched with regards to demographics and fracture type. The overall union rate was similar in both groups but the time to union was shorter in the TAN group. There were 8 implant failures in the PFNA (22.2%) group compare to none in the TAN group. Implant failure was associated with the severity of fracture (AO 31.A3.3) but was not related to fracture malreduction or screw position (Tip-apex-distance). Our study suggests that the use of reconstruction system with two screws such as TAN may be more suitable implant for reverse oblique intertrochanteric hip fractures.

    Polycomb repressive complex two (PRC2) has been implicated in embryonic stem (ES) cell pluripotency; however, the mechanistic roles of this complex are unclear. It was assumed that ES cells contain PRC2 with the same subunit composition as that identified in HeLa cells and Drosophila embryos. Here, we report that PRC2 in mouse ES cells contains at least three additional subunits: JARID2, MTF2, and a novel protein denoted esPRC2p48. JARID2, MTF2, and esPRC2p48 are highly expressed in mouse ES cells compared to differentiated cells. Importantly, knockdowns of JARID2, MTF2, or esPRC2p48 alter the level of PRC2-mediated H3K27 methylation and result in the expression of differentiation-associated genes in ES cells. Interestingly, expression of JARID2, MTF2, and esPRC2p48 together, but not individually, enhances Oct4/Sox2/Klf4-mediated reprograming of mouse embryonic fibroblasts (MEFs) into induced pluripotent stem cells, whereas knockdown or knockout of JARID2, MTF2, or esPRC2p48 significantly inhibits reprograming. JARID2, MTF2, and esPRC2p48 modulate H3K27 methylation and facilitate repression of lineage-associated gene expression when transduced into MEFs, and synergistically stimulate the histone methyl-transferase activity of PRC2 in vitro. Therefore, these studies identify JARID2, MTF2, and esPRC2p48 as important regulatory subunits of PRC2 in ES cells and reveal critical functions of these subunits in modulating PRC2’s activity and gene expression both in ES cells and during somatic cell reprograming.

    Phenotypic plasticity is the ability of a given genotype to produce different phenotypes in response to distinct environmental conditions. Phenotypic plasticity can be adaptive. Furthermore, it is thought to facilitate evolution. Although phenotypic plasticity is a widespread phenomenon, its molecular mechanisms are only beginning to be unravelled. Environmental conditions can affect gene expression through modification of chromatin structure, mainly via histone modifications, nucleosome remodelling or DNA methylation, suggesting that phenotypic plasticity might partly be due to chromatin plasticity. As a model of phenotypic plasticity, we study abdominal pigmentation of Drosophila melanogaster females, which is temperature sensitive. Abdominal pigmentation is indeed darker in females grown at 18°C than at 29°C. This phenomenon is thought to be adaptive as the dark pigmentation produced at lower temperature increases body temperature. We show here that temperature modulates the expression of tan (t), a pigmentation gene involved in melanin production. t is expressed 7 times more at 18°C than at 29°C in female abdominal epidermis. Genetic experiments show that modulation of t expression by temperature is essential for female abdominal pigmentation plasticity. Temperature modulates the activity of an enhancer of t without modifying compaction of its chromatin or level of the active histone mark H3K27ac. By contrast, the active mark H3K4me3 on the t promoter is strongly modulated by temperature. The H3K4 methyl-transferase involved in this process is likely Trithorax, as we show that it regulates t expression and the H3K4me3 level on the t promoter and also participates in female pigmentation and its plasticity. Interestingly, t was previously shown to be involved in inter-individual variation of female abdominal pigmentation in Drosophila melanogaster, and in abdominal pigmentation divergence between Drosophila species.

    Local environmental conditions (i.e., density and angular momentum properties of protogalactic clouds) are thought to be factors affecting the ultimate morphology of a galaxy. The existence of significant numbers of mixed morphology (E/SO+S) pairs of galaxies would represent a direct challenge to this idea unless all early-type components are formed by mergers. The authors wished to isolate candidate E+S pairs for detailed study. The authors have observed 22 pairs of mixed morphology galaxies (containing at least one early-type component) selected from a catalog of Sulentic (1988: unpublished) based upon the ESO sky survey. The observed sample and relevant morphological and interaction characteristics are summarized in tabular form. The authors report the relevant geometrical properties of the galaxies in another table. They list the maximum values measured for the ellipticity and the a(4)/a shape parameter together with the total measured twisting along the profile beyond the seeing disk (they set an inner limit of 3 arcsed). An asterisk indicates objects in which a(4)/a is neither predominantly boxy nor disky. They found a large number of true mixed pairs with 13/22 E+S pairs in the present sample. The remaining objects include 5 disk pairs (composed of SO and S members) and 3 early-type pairs comprising E and SO members. They estimate that between 25 and 50 percent of the pairs in any complete sample will be of the E+S type. This suggests that 100 to 200 such pairs exist on the sky brighter than m sub pg = 16.0. They found no global evidence for a difference between E members of this sample and those in more general samples (e.g., Bender et al. 1989). In particular, they found that about 30 percent of the early-type galaxies cannot be classified either predominantly boxy or disky because the a(4)/a profile shows both of these features at a comparable level or does not show any significant trend. Isophotal twisting is observed with a range and distribution

    The first amateur observation of an exoplanet was made from the Nyrola Observatory in September 16, 2000. (Marko Moilanen, Jalo Ojanperä, Jouni Sorvari, Aki Id and Arto Oksanen). The jovian-type planet orbits a star that is 153 light years far away, and was called HD209458b in Pegasus [1]. The equipment used by this Observatory was a 16 inches MEADE LX200, a ST7E CCD SBIG camera with a V photometric filter and an f/6.3 focal distance reducer. At the University of Nariño Observatory we have a similar equipment. The equipment we employed is: 14"LX200 GPS MEADE telescope and STL-1001 SBIG. The camera we used in our search is much more sensible than the one used by the Nyrola Observatory [2]. From the Astronomical Observatory at the University of Nariño-COLOMBIA, we begun a systematic search for exoplanets. We have already confirmed the transit of the exoplanet TrES-3. This exoplanet was discovered by O'Donovan and other investigators, and turns around the GSC 03089- 00929, with an orbital period of 1.30619 days (31.34856 hours) and inclination of 82.15 deg [3]. The TrES-3 is quite interesting because it has one of the smallest periods found on exoplanets. Jessie L. Christiansen, et.al. observed seven transits and they found that the duration of transit is 81.9+/-1.1 minutes and inclination of 81.99+/-0.30 deg [4], [5]. We have captured a lot of data to elaborate the lightcurves so we can estimate the physical parameters of the exoplanet.

    Tan spot and Septoria nodorum blotch (SNB) are important diseases of wheat caused by the necrotrophic fungi Pyrenophora tritici-repentis and Parastagonospora nodorum, respectively. The P. tritici-repentis necrotrophic effector (NE) Ptr ToxB causes tan spot when recognized by the Tsc2 gene. The NE ToxA is produced by both pathogens and has been associated with the development of both tan spot and SNB when recognized by the wheat Tsn1 gene. Most work to study these interactions has been conducted in common wheat, but little has been done in durum wheat. Here, quantitative trait loci (QTL) analysis of a segregating biparental population indicated that the Tsc2-Ptr ToxB interaction plays a prominent role in the development of tan spot in durum. However, analysis of two biparental populations indicated that the Tsn1-ToxA interaction was not associated with the development of tan spot, but was strongly associated with the development of SNB. Pa. nodorum expressed ToxA at high levels in infected Tsn1 plants, whereas ToxA expression in P. tritici-repentis was barely detectable, suggesting that the differences in disease levels associated with the Tsn1-ToxA interaction were due to differences in pathogen expression of ToxA. These and previous results together indicate that: (1) the effects of Tsn1-ToxA on tan spot in common wheat can range from nonsignificant to highly significant depending on the host genetic background; (2) Tsn1-ToxA is not a significant factor for tan spot development in durum wheat; and (3) Tsn1-ToxA plays a major role in SNB development in both common and durum wheat. Durum and common wheat breeders alike should strive to remove both Tsc2 and Tsn1 from their materials to achieve disease resistance. PMID:27777262

Durum and common wheat breeders alike should strive to remove both Tsc2 and Tsn1 from their materials to achieve disease resistance.
