    Full Text Available Se realizó una revisión de los trabajos sobre bienestar subjetivo publicados en el mundo en los últimos años y se analizaron críticamente los resultados obtenidos tomando en consideración algunos de los fundamentos epistemológicos que les sirvieron de sustento. La enorme vigencia de los estudios sobre bienestar subjetivo en la actualidad pone de manifiesto la creciente conciencia de los investigadores acerca de la importancia del estudio de los factores que tributan a la salud desde una perspectiva positiva. La comprensión de la compleja madeja de interacciones que determinan el bienestar subjetivo en los niveles macrosocial, microsocial e individual, resulta requisito indispensable para la instrumentación de intervenciones en el nivel primario de atención y así elevar dicho indicador, tan ligado a la salud.A review of the papers on subjective well-being published in the world during the last years was made. The results obtained were critically analyzed taking into account the epistemological foundations that served as a sustenance. The fact that the studies about subjective well-being are still in force shows the increasing awareness of the investigators about the importance of studying those factors influencing positively on health. The understanding of the complex skein of interactions determining the subjective well-being at the macrosocial, microsocial and individual levels is an indispensable requirement for the implementation of interventions at the primary health care level and for elevating this indicator so closely related to health.

  6. Motivos, personalidad y bienestar subjetivo en el voluntariado

    2015-10-01

    Full Text Available El principal objetivo de este estudio fue analizar las relaciones entre las motivaciones del individuo para participar en actividades de voluntariado, los rasgos de personalidad y el bienestar subjetivo. Participaron 153 adultos, de edades entre los 17 y 65 años, que cumplimentaron las distintas medidas tanto on-line como en papel y lápiz. Los resultados mostraron que las motivaciones previas diferían entre los dos grupos de voluntarios. Los análisis correlacionales indicaron que algunos motivos como petición de la organización, circunstancias personales o experiencias vividas se asociaban a satisfacción vital y a emociones negativas en los voluntarios on-line, mientras que hacer algo útil o sentimientos de paz eran los motivos asociados a estos indicadores de bienestar para los voluntarios de la prueba en papel. Los rasgos de personalidad, principalmente el neuroticismo, mostraron relaciones más consistentes con el bienestar que las motivaciones en ambos grupos de voluntarios. Los análisis de regresión indicaron que las facetas de extraversión, como el gregarismo, la calidez o la actividad, fueron los predictores más potentes del bienestar de los voluntarios que hicieron las pruebas en papel; mientras que la disciplina, faceta de la responsabilidad, y la estabilidad emocional predecían el bienestar de los voluntarios on-line. Estos hallazgos sugieren que existen distintos perfiles de voluntarios que podrían estar determinando su participación en diversas actividades o colectivos. Además, las características personales parecen tener un mayor efecto en el bienestar que las motivaciones.

    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. Copyright © 2010 Elsevier Ltd. All rights reserved.

    1981-01-01

    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

    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

    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.

    Full Text Available Se buscó comprender el universo subjetivo que sustenta las acciones agresivas entre pares en el medio escolar. Para ello se realizó un estudio cualitativo con dos niños de cinco años en un colegio de estrato socio-económico medio de la ciudad de Cali. Las observaciones se realizaron durante seis sesiones individuales en las cuales se les propusieron distintos instrumentos clínicos: juego, dibujo y entrevista. Se encontró que los niños presentan graves dificultades en la construcción de los fundamentos identitarios y, por lo tanto, una insuficiente definición de las fronteras con el otro, todo lo cual está acompañado de un profundo sentimiento de amenaza a la permanencia de sí. En consecuencia, los niños constituyen las acciones agresivas como un recurso de protección y su modo primordial de relación con el otro.

    Full Text Available As inter-relações do envolvimento religioso com o bem-estar subjetivo em idosos foram investigadas neste trabalho. Participaram da pesquisa 256 indivíduos de ambos os sexos, com idades variando de 60 a 90 anos, que responderam a três instrumentos destinados a mensurar sua satisfação com a vida, seus afetos positivos e negativos e seu envolvimento religioso bem como a perguntas de natureza sociodemográfica. Os resultados evidenciaram que, dentre as dimensões do envolvimento religioso, apenas a religiosidade subjetiva se correlacionou positiva e significativamente com a satisfação com a vida, que não foram observadas correlações entre o envolvimento religioso e os afetos positivos e negativos, e que os idosos protestantes apresentaram níveis mais elevados de afetos positivos que os católicos. Tais resultados são discutidos à luz dos estudos empíricos e dos modelos conceituais que deram suporte à pesquisa.

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

    Reed, Derek D; Kaplan, Brent A; Becirevic, Amel; Roma, Peter G; Hursh, Steven R

    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. © 2016 Society for the Experimental Analysis of Behavior.

  11. [What nosographic framework for excessive tanning?].

    2014-04-01

    Socially valorised tanning, like other forms of behaviour, can take on an addictive aspect. Excessive tanning, defined by the presence of impulsivity and repetition of tanning that leads to personal distress, is a psychiatric disorder that has only recently been recognized. This finding is based on the observations of many dermatologists who report an addictive relationship in their patients with tanning cabins despite announcement of the diagnosis of malignant melanoma. This article attempts to synthesize the existing literature on excessive tanning and addiction to investigate possible associations. This review focuses on the prevalence, clinical features, aetiology, and treatment of this disorder. The literature review was conducted from 1983 to 2012, using PubMed, Google Scholar, EMBASE, and PsycInfo, using the following keywords alone or combined: Tanning, Addiction, Sunbeds, Skin cancer prevention, and Treatment. We investigated different models to determine how excessive tanning met these criteria. Excessive Tanning was described in the 2000s by an American dermatologist, Carolyn Heckman. Wartham et al. were the first to have proposed a theoretical framework for addiction to sunbathing, as well as two scales (m CAGE and m DSM IV) for the diagnosis and to assess the degree of addiction. These diagnostic criteria describe the craving like-symptoms, the feeling of losing control, or the continuation of the behavior despite knowledge of negative consequences. Excessive Tanning is not present in the classifications of the DSM or ICD, but may be related to Addiction, Obsessive-Compulsive Disorder, Impulse control disorders, Anorexia, or Body Dysmorphic Disorder. Excessive tanning can be included in the spectrum of behavioural addictions due its clinical characteristics in common with classics addictive disorders. They are a variety of other models, which may offer an explanation for or insight into tanning behaviour. Further studies must be controlled, notably on

    The etiopathogenesis of the algo-dysfunctional syndromes, which include chronic fatigue syndrome, fibromyalgia and irritable bowel syndrome, is still debated, but it is widely accepted that it is best described by a multifactorial model that include genes, environmental factors such as external infections, inflammation, dietary habits, impaired endogenous cortisol production, the aberrant activation of some areas of the central nervous system, and small peripheral nervous fibre damage. This complexity suggests that they should be managed by means of a multidisciplinary approach involving the use of both pharmacological and non-pharmacological treatments. The aim of this review is to discuss the most recent scientific acquisitions concerning these syndromes and their treatment.

    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. © The Author(s) 2014.

    Maria Carmen Villela Rosa Tacca

    Full Text Available Neste artigo, procuramos identificar como o sentido subjetivo se manifesta e está na base dos processos de aprendizagem de cada aluno, revelando a sua singularidade enquanto pessoa. Para essa compreensão, foi realizada uma pesquisa com base nas categorias de subjetividade e sentido subjetivo de González Rey. Nela esteve envolvida uma professora e sua turma de 4ª série do ensino fundamental. Na análise dos dados, foi possível compreender as formas como os alunos utilizavam as informações que constavam das atividades na conjuntura de seus recursos pessoais, no que emergiam diferentes sentidos subjetivos para construir caminhos de aprendizagem. Conclui-se que a aprendizagem se encontra envolvida com a produção de sentidos subjetivos procedentes dos diferentes espaços e situações de vida do aluno. Assim, considerar essa dimensão permitiria ações diferenciadas orientadas ao apoio à criança no avanço contínuo de sua escolaridade.

    Full Text Available El propósito de esta investigación ha consistido en analizar las diferencias en bienestar subjetivo en 346 estudiantes universitarios pertenecientes a dos culturas: colectivista (México e individualista (España. El bienestar subjetivo global se evaluó mediante la satisfacción vital, la felicidad, las emociones positivas y negativas; considerándose además, cuatro indicadores de satisfacción en dominios específicos: sentimental, estudios, salud y ocio. Los resultados indican que los estudiantes mexicanos puntúan más alto que los españoles en todos los indicadores de bienestar subjetivo. Los análisis de regresión múltiple revelan la importancia de la satisfacción sentimental y con los estudios en la felicidad y satisfacción vital de ambas culturas. Además, son importantes en la predicción del bienestar subjetivo global, la satisfacción con la salud para los mexicanos y la satisfacción con el ocio para los españoles. Los resultados apoyan el efecto diferencial de la cultura en el bienestar, fundamentalmente en su predicción a través de la satisfacción en ciertos dominios específicos.

    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.

    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. © 2014 The International Society of Dermatology.

Después guardaremos la editorial en un cajón y desarrollaremos el número de la revista. Dentro de unos meses, sacaremos ese croquis y podremos reconocer su eficacia; sufrirá algún retoque pero esperamos que aún sea válido.Un viaje comienza con un empeño, un destino o una finalidad. Esta revista se ofrece en cada número con un carácter poliédrico acotando faceta a faceta, la definición de Arquitectura. Siempre que hablamos de ella intentamos conocerla, delimitarla y hay quien piensa que en su anatomía puede encerrarse el secreto de algo que es inaprensible. Paso a paso nos acercamos a su conocimiento lentamente, gracias a un esfuerzo parecido al del trabajo de Sísifo. Lo más acertado sería pensar que nuestro acercamiento es parecido al recorrido de una cinta de Moebius y aunque consigamos agotar el recorrido, siempre seremos conscientes de la breve e inasible distancia existente en el mismo punto de cada lado de la cinta. Este viaje que muchos quieren entender como absurdo, es el viaje de lo subjetivo, de aquello que nos permite acercarnos a las ideas para conocerlas poco a poco, lentamente, frente al eficaz conocimiento lógico, analítico, anatómico que, como el niño que desmonta los objetos, algunos investigadores intentan aplicar, desmontando los edificios, pensando que dentro están las ideas. No obstante todos se ven obligados a reconocer que ese trabajo sí que es absurdo porque nos lleva a la nada, quizás solo a la destrucción del pensamiento a favor del conocimiento ineficaz de la realidad.El otro conocimiento que proponemos consiste en una actitud alternativa, aquella que reivindica lo subjetivo frente a lo objetivo, para establecer como mecanismo de conocimiento una acotación del mundo que nos rodea, de los temas que nos

    Full Text Available The research was aimed to investigate the influence of minimizing chromium use on combined chromium-gambier process upon the characteristics of tanned leather. At the first stage of tanning process, chromium was used and in the second stage it was replaced by gambier. The raw material used was dried saline-preserved goat skin. The treatments applied on the tanning process were the different concentrations of chromium ranging from the highest level of 6% to the lowest level of 1% which was then re-tanned by using 8% concentration of gambier. The examination parameters included chemical and physical properties as well as visual investigation on the tanned leather in accordance with SNI-06-0463-1989-A. The result showed that the tanning process by using 2% chromium in the first step and 8% gambier in the second step was a treatment combination producing tanned leather that met the standard. The examination on tanned leather resulted from such treatment showed 56.33% rawhide, 17.45% of bound tannin, 31.22% of tanning level, tensile strength 386.30 kg/cm2, flexibility 31.91%, leather width 1.3 mm, density 0.75 g/cm3, the leather was quite elastic with light brownish color. In conclusion, minimizing the use of chromium in the combined tanning process of chromium and gambier can be implemented to the lowest of 2% chromium concentration and 8% gambier in the first and second step, respectively.

    The US Food and Drug Administration has classified tanning beds as carcinogenic. Most states have enacted legislation to prevent or create barriers for minors accessing tanning establishments. Determining tanning salon compliance with legislation would provide an indication of the influence of legislation at preventing exposure to the carcinogen in minors. To investigate compliance rates in the 42 states and the District of Columbia with legislation restricting tanning bed use in minors and to identify differences in compliance based on population, regional location, salon ownership, age group being regulated, and time since the law was enacted. This investigation was a cross-sectional telephone survey conducted between February 1, 2015, and April 30, 2016, by callers posing as minors attempting to schedule a tanning appointment. The setting was tanning salons in the 42 states and the District of Columbia that currently have legislation restricting tanning bed use in minors. Included in the study were 427 tanning salons, 10 randomly selected from each state or territory with tanning legislation. Overall compliance of tanning salons with state tanning legislation and differences in compliance based on community population, regional location, independent vs chain tanning salon, age group being regulated, and time since the law was enacted. Of the 427 tanning salons surveyed, overall noncompliance with state legislation was 37.2% (n = 159). There were more noncompliant tanning salons in rural locations (45.5%; 95% CI, 37.5%-53.7%; P = .009), southern regions of the United States (49.4%; 95% CI, 41.4%-57.4%; P = .001), independently owned salons (43.9%; 95% CI, 37.3%-50.6%; P = .003), states with younger age groups being regulated (53.5%; 95% CI, 45.7%-61.2%; P legislation aimed at limiting tanning bed use among US minors is unsatisfactory, indicating that additional efforts to enforce the laws and education of the harmful effects of UV tanning are

    Full Text Available Resumo Objetiva-se analisar a pobreza multidimensional e seus aspectos subjetivos em contextos rural e urbano em um Estado do Brasil. Os aspectos subjetivos da pobreza estão relacionados a uma autopercepção vinculada à privação financeira e à responsabilização individual. A amostra total constou de 417 participantes. Foi desenvolvido um Índice de Mensuração de Pobreza Multidimensional a partir das privações nas dimensões habitação, escolaridade, trabalho/renda, saúde e aspectos subjetivos da pobreza. Foram realizados testes de Análise de Regressão Múltipla e Análise Multivariada de Variância. Identificou-se que as privações nas dimensões escolaridade e habitação são mais intensas na zona rural. Já a dimensão subjetiva da pobreza é mais forte no contexto urbano. Em ambos os contextos, dimensão privação de trabalho/renda tem predição positiva com os aspectos subjetivos da pobreza. No contexto urbano, as dimensões saúde e habitação também são preditoras positivas da dimensão subjetiva da pobreza, enquanto a dimensão educação tem uma correlação negativa.

    To examine construct and predictive utility of an adapted cognitive rationalization scale for tanning-bed use. Current/former tanning-bedusing undergraduate students (N = 216; 87.6% females; 78.4% white) at a large northeastern university participated in a survey. A cognitive rationalization for tanning-bed use scale was adapted. Standardized self-report measures of past tanning-bed use, advantages of tanning, perceived vulnerability to photoaging, tanning-bed use dependence, and tanning-bed use intention were also administered. The cognitive rationalization scale exhibited strong construct and predictive validity. Current tanners and tanning-bed-use-dependent participants endorsed rationalizations more strongly than did former tanners and not-tanning-bed-use-dependent participants respectively. Findings indicate that cognitive rationalizations help explain discrepancy between inconsistent cognitions.

    2017-04-15

    Many young adults have utilized indoor ultraviolet(UV) tanning, putting them at higher risk for development of skin cancers. Prior to the increased regulations on indoor tanning for minors, indoor tanning businesses marketed to teens through modalities such as advertisements in high school newspapers. The purpose of this study was to quantify tanning advertisements in high school newspapers published across the United States between August 2014 and July 2015. Online versions of the newspaper issues were available on issuu.com. Tanning advertisements appeared in 3 of 23 high school newspapers with advertisements of any kind(13%). Among all newspapers with advertisements, 10% were indoor tanning advertisements. One newspaper in Colorado contained advertisements of any kind and had 0 tanning advertisements. A prior study of Colorado high schools showed 11 of 23 schools (48%) to contain tanning advertisements. This suggests that there may be a decrease in indoor UV tanning advertisements owing to increased tanning regulation by state legislatures, national attention to UV tanning, or a general decrease in high school tanning advertisements.

    Full Text Available Se presentan resultados de una investigación realizada con el objetivo definir la referencialidad partiendo del proceso de socialización y la construcción del bienestar subjetivo, en la que participaron 11 jóvenes de 20 a 26 años de Medellín. La modalidad de investigación adoptada fue la teoría fundamentada y los datos fueron obtenidos a través de dos grupos de discusión y cuatro entrevistas semiestructuradas. Como parte de los resultados se destacan las tensiones a considerar para la definición de la referencialidad, su constitución a través de las relaciones significativas que establecen los y las jóvenes con personas dentro y fuera de la familia, y la forma como multiplicidad de relaciones influyen positivamente en la consecución de mejores condiciones de bienestar subjetivo. Las conclusiones dejan ver posibilidades de integración del concepto, construido como orientador de intervenciones psicosociales y de políticas públicas sobre familia y juventud.

    Full Text Available ‘Bibliotecas digitales’ … ¿estamos hablando de una novela de Isaac Asimov o Ursula LeGuin? ¿Aludimos a alguna escena futurista de una película de ciencia ficción? ¿Entrevemos instrumentos utópicos salidos de una imaginación vanguardista?. No. Las bibliotecas digitales ya han llegado y están entre nosotros. Casi sin darnos cuenta y sin mucho tiempo para reflexionar sobre ellas, se han instalado en nuestro entorno de una manera impensable hace unas décadas; un entorno que se va perfeccionando con el tiempo, de un modo que a veces nos hace preguntarnos cómo se estudiaba e investigaba antes de su llegada.

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

    Mengistie, Embialle; Smets, Ilse; Van Gerven, Tom

    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.

  14. Pollution and energy management in tanning industry

    International Nuclear Information System (INIS)

    Zaman, N.U.

    2005-01-01

    Tanning industry uses a number of chemicals such as Common Salt, Lime (Calcium Hydroxide), Sodium Sulfide and Basic Chromium Sulfate etc. During process, only a part of the chemical is consumed and the rest ends up in the effluent as pollutant. This paper deals with the techniques, locally developed or published in literature to recycle these chemicals and also discusses some energy saving techniques which can be used in tanning industry. Basic Chromium Sulfate (BCS) is one of the expensive chemicals used in 'Chrome Tanning'. By precipitating d filtering basic chromium sulfate, the recovery is nearly complete and the effluent obtained contains less than 1ppm Chromium. Dried raw hides contain up to 15% sodium chloride (w/w) and this can be removed in solid form by using mechanical brushes and can be re-used. The recovered salt contains foreign matter as impurities. After dissolution in water, the salt solution is filtered through cartridge filters and can be used in pickle bath. Liming slurry containing sodium sulfide is wasted as it contains fleshing and hair etc. A self cleaning 'J' type screen has no moving parts and removes fleshing and hair from the lime suspension. 'Counter Current Washing Technique,' reduces the wash water quantity by a factor of five to six. Air born pollution generated during buffing and dyeing can be captured by properly designed air filters. The solvents released in atmosphere during dyeing and finishing can be recovered by absorption. Fat, gelatin and protein can be recovered from waste fleshing. In tanning industry, drying of hides is the major consumer of thermal energy. Hot air can be produced by steam, hot water or solar energy. Advantages and disadvantages of these options are discussed. Wastage of thermal energy in dryers can be reduced by improving the existing designs. Hot water for tanning purposes can be generated by recovering waste heat present in the boiler flue gases. Boiler efficiency can also be improved by cycling heat

    Full Text Available In the present paper we analyze the determinants of happiness proxying by subjective welfare. The main objective is twofold: on the one hand, to put to the test the Easterlin’s paradox (the lack of a direct relationship between income and subjective wellbeing at aggregate level and, on the other hand, to weight influence of relational goods in determining happiness. The analytical framework adopts the perspective of happiness economics and the empirical evidence is derived from the estimation of a microeconometric function of happiness applying a Logit model both when using cross sectional and panel data. The results show that in Spanish society income plays a secondary and subjective role, while other variables that are associated directly or indirectly to relational goods are revealed to be very important.En el presente trabajo se analizan los determinantes de la felicidad, entendida esta como satisfacción subjetiva revelada. El principal objetivo tiene un doble componente: por un lado, se trata de contrastar la paradoja de Easterlin para la sociedad española (ausencia de un vínculo directo entre el incremento de la renta per capita y la evolución del bienestar subjetivo revelado a nivel agregado y, por otro, evaluar el papel que desempeñan los bienes relacionales como determinantes de la felicidad. El marco analítico adoptado se encuadra dentro de la denominada happiness economics y la evidencia empírica se deriva de la estimación de una función microeconométrica de la felicidad aplicando un modelo Logit tanto en cortes temporales como en datos de panel. Los resultados obtenidos permiten concluir que en España el ingreso desempeña un papel secundario y subjetivo, mientras que se revelan como importantes las variables asociadas directa o indirectamente a los bienes relacionales.

    Ultraviolet radiation exposure through natural sunlight or tanning lamps is a risk factor for skin cancer. As the media can influence behavior, we studied whether watching reality television (TV) beauty shows is associated with tanning lamp use or outdoor tanning. College students (n = 576) were surveyed on their reality TV beauty show watching, their use of tanning lamps, and outdoor tanning behavior. We asked media attitude questions about connectivity with reality TV shows and Internet use of Facebook to discuss reality TV shows. Those who did versus did not watch reality TV beauty shows used tanning lamps (12.9% vs 3.7%, P watching reality TV beauty shows (odds ratio [OR] 2.58, 95% confidence interval [CI] 1.11-6.00), increasing age (OR 1.17, 95% CI 1.04-1.32), and female sex (OR 10.16, 95% CI 3.29-31.41). Significant predictors of outdoor tanning included watching reality TV beauty shows (OR 2.11, 95% CI 1.33-3.34). The specific names of the reality TV beauty shows watched were not obtained and therefore we cannot determine if particular shows were more or less associated with this behavior. Watching reality TV beauty shows is associated with both tanning lamp use and outdoor tanning. Dermatologists should consider discussing the potential harmful aspects of tanning beds and outdoor tanning, especially with their patients who watch reality TV beauty shows.

    Summary The relationship between human skin pigmentation and protection from ultraviolet (UV) radiation is an important element underlying differences in skin carcinogenesis rates. The association between UV damage and the risk of skin cancer is clear, yet a strategic balance in exposure to UV needs to be met. Dark skin is protected from UV-induced DNA damage significantly more than light skin due to the constitutively higher pigmentation but an as yet unresolved and important question is what photoprotective benefit, if any, is afforded by facultative pigmentation (i.e. a tan induced by UV exposure). To address that and to compare the effects of various wavelengths of UV, we repetitively exposed human skin to suberythemal doses of UVA and/or UVB over 2 weeks after which a challenge dose of UVA&UVB was given. Although visual skin pigmentation (tanning) elicited by the different UV exposure protocols was similar, the melanin content and UV-protective effects against DNA damage in UVB-tanned skin (but not in UVA-tanned skin) were significantly higher. UVA-induced tans seem to result from the photooxidation of existing melanin and its precursors with some redistribution of pigment granules while UVB stimulates melanocytes to up-regulate melanin synthesis and increases pigmentation coverage, effects that are synergistically stimulated in UVA and UVB-exposed skin. Thus, UVA-tanning contributes essentially no photoprotection, although all types of UV-induced tanning result in DNA and cellular damage which can eventually lead to photocarcinogenesis.

    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. Copyright © 2011 Elsevier B.V. All rights reserved.

    Full Text Available A spent tanning bath contains high concentration of salts, chromium and protein. The treatment system for removal of chlorides or chromium from this effluent is expensive. In this context this waste has to be reused. Our study focuses on the application of advanced oxidation processes for protein removal present in a tanning bath. To improve the quality of the chromium tanning bath, two electrochemical processes (electrooxidation and peroxi-electrocoagulation process, PEP are investigated in a batch reactor. The effects of operational parameters such as reactor configuration, current density and electrolysis time on chemical oxygen demand (COD and protein removal efficiency are examined. Results indicated that under the optimum operating range for process, the COD and protein removal efficiency reached 53 and 100%, respectively. The optimum values are determined for the hybrid process (PEP under 0.13 A·cm−2 over 2 h. The treated tanning bath is used as a tanning solution in leather processing. The influence of chromium salt dose, pH solution, stirring time and contact time on the leather characteristic is evaluated. The hides tanned after the addition of 0.25% of commercial chromium salt, at pH solution, leaving them stirring for 4 h with a contact time of 2 days, and showed good hydrothermal stability and physical characteristics of leather.

    To determine whether a tan produced by 8-MOP and UVA protects from subsequent solar light irradiation, volunteers were irradiated with unfiltered Xenon arc light before and 10 days after a 1 week's course of four 8-MOP-UVA treatments. Evaluation of the minimal erythema doses and of histological changes before and after 8-MOP-UVA treatment revealed that the 8-MOP-UVA induced tan protected against the erythemogenic and cell damaging effects of Xenon arc light. Unscheduled repair DNA synthesis, used as a measure for UVB-induced DNA damage and repair, was also investigated in skin irradiated with the Xenon arc before and after 8-MOP-UVA induced tanning. Both the number of grains per sparse labeled cell and the number of sparse labeled cells per 1000 cells, were found to be significantly lower in tanned skin; taking decreased unscheduled repair DNA synthesis as a measure for decreased DNA-damage, these findings also demonstrate a photoprotective effect of the 8-MOP-UVA induced tan.

    Full Text Available Leather is one of the most globally spread biomaterial which is obtained by the processing of different animal skins. It encompasses a wide palette of applications, from footwear and clothing to upholsteries and different types of furniture [1], [2], [3]. The main constituent of animal skins is collagen, a supramolecular fibrillar protein in the form of a triple helix. This form endows leather with elasticity, good mechanical properties and softness. A major disadvantage resides in the inapplicability of raw animal hides, due to their microbiological instability and decay through rotting. Microbiological stability is obtained through the tanning process, characterized by protein crosslinking and drying afterwards. After tanning the leather exhibits the required properties for the desired specific applications in terms of aspect, availability and sustainability [4], [5]. The study aims to elucidate the thermal decomposition process of chrome-free tanned bovine hide (wet-white using a new product based on titanium and aluminium salts compared with the same hide tanned by chromium salts (wet-blue. The thermal behavior was studied by dynamic thermogravimetry in nitrogen atmosphere, up to 700 oC. A comparative thermal decomposition study between the different tanned bovine leathers was undertaken.

    To report the case of a patient with keratoconus who developed a corneal perforation secondary to UV radiation from a tanning lamp. We believe this to be the first case of a corneal perforation secondary to UV radiation. The presentation and management of the patient and the pathophysiology of UV keratitis are discussed. Our patient developed a full-thickness corneal perforation after 30 minutes of tanning lamp exposure without eye protection. The cornea was temporized with cyanoacrylate tissue adhesive until penetrating keratoplasty could be performed. With an increased understanding of the pathophysiology of UV damage, treatment should be aimed at modulating the disease to reduce the likelihood of a poor outcome.

    2012-05-01

    Full Text Available ¿Qué utilidad tiene el enfoque de bienestar subjetivo para el estudio, análisis y hechura de la política pública? En este trabajo argumento que la utilidad se aprecia en varios aspectos. El enfoque de bienestar subjetivo ofrece nuevas formas de poner a prueba supuestos básicos del análisis económico y social sobre el comportamiento humano; ofrece herramientas de análisis que dan una perspectiva diferente y complementaria a mediciones y enfoques tradicionales sobre los aspectos que más importan a la población en su proceso de desarrollo; ofrece un conjunto de reflexiones importantes sobre las implicaciones del estudio de la felicidad y la satisfacción para diferentes tipos de políticas públicas y en distintos ámbitos de la acción gubernamental. Estos aspectos se analizan a partir de un rastreo histórico sobre los orígenes de la “ciencia del bienestar subjetivo o de la felicidad” y de una revisión de la literatura para identificar temas abordados, herramientas desarrolladas y políticas públicas implicadas en el estudio sobre el bienestar subjetivo en décadas recientes. Una de las ideas centrales de este trabajo es que más que elevar los niveles de felicidad y satisfacción de las personas, en sí mismo importante, se trata de encontrar formas de reducir la brecha entre los objetivos de desarrollo que tiene la política pública, por un lado, y el bienestar subjetivo de la población, por el otro, a partir de una mejor comprensión de las preferencias y comportamientos de los individuos y lo que afecta la satisfacción de las personas con su vida.

    Full Text Available Este trabajo describe el empleo de las redes sistémicas para analizar las concepciones de un grupo de estudiantes de la carrera de biología acerca del tamaño del átomo. Las respuestas a la pregunta ¿qué tan grande es un átomo? se evaluaron antes y después del estudio de los temas de estequiometría y estructura atómica. El análisis de las redes permitió identificar que, después del estudio de los temas mencionados, la red se hace más compleja como evidencia de un cambio en las respuestas. No obstante, las categorías de la red antes y después de la intervención didáctica se mantienen. Al final del proceso, una gran parte de los estudiantes que no tenían respuesta a la pregunta propuesta inicialmente se posicionan y adoptan como solución la comparación con elementos que conocen, siempre relacionando algo “muy grande” con algo “muy pequeño”.

    Full Text Available Introduction. Tanning devices are sources of UVA and UVB radiation. UV exposure can cause damage to the cornea of the eye, skin burns and even skin cancer. Appropriate use of solarium requires adequate knowledge of health effects resulting from the excessive use of sunbeds. The aim of the study was to examine knowledge, attitudes and habits in the solarium use. Material and methods. The study was based on our own questionnaire distributed among the citizens of a city located in Łódź Province. The study group consisted of 135 adults, mostly women and people with secondary and vocational education. Participants of the study were asked to answer specific questions included in the questionnaire concerning the knowledge of UV radiation, attitudes and the behaviour in the solarium. Results. 36% of the respondents were going to the solarium. 38% of the respondents weren’t going at all. Every fourth respondent used to go to the solarium in the past, however gave up this type of tanning for some reasons. Protecting goggles were used only by 18% of the respondents. 94% of the respondents never asked the service about CE certificates for the sunbeds intended for use. Conclusions. People tanning in the solarium, in comparison to those who do not use the artificial sun, enjoy better knowledge of the ultraviolet radiation. However they do not follow the requirements of the safe tanning. They are also not interested in technical conditions of the sunbeds. People who are not tanning in the solarium are more aware of health effects caused by UV radiation. Actions promoting public awareness on negative health effects of exposure to UV radiation in the solarium are needed.

    2017-05-01

    Full Text Available Leather is a high tech material with different application fields, such as automotive, manufacturing of leatherwear articles or clothing and footwear. Leather is a biomaterial obtained by processing animal skins. Unfortunately, raw animal hides are practically inutilizable, due to their microbiological instability and are affected by rotting. Microbiological stability is achieved by tanning, when the protein is crosslinked, followed by drying. After crosslinking and drying, the new material shows the required properties of sustainability, availability and an esthetically pleasing aspect to the touch, making it available across its entire range of applications. From a structural point of view the animal skins are constituted of collagen, which is a fibrilar protein with a high degree of supramolecular organization in triple helix form that endows softness, elasticity and mechanical strength. High quality standards and lack of toxicity are required in all cases. Leather colour changes during exposure to light radiations are considered a consequence of the presence of some products with weak photochemical resistance during fabrication. The study aims to compare changes in properties of leathers obtained using mineral tanning agents such as Cr III salts and those obtained with the more environment-friendly technology using acid hydrolysis. Accelerated aging studies were conducted on tanned leathers by exposing the samples to UV radiation with different irradiation doses and two wavelengths (254 and 365 nm under controlled humidity and temperature conditions. Structural changes caused by irradiation were studied by FTIR. Colour changes on the sample surfaces were assessed during irradiation with the CIEL a*b* system. The colour parameters variation (L*, a*, b* and colour differences have been discussed in correlation with structural changes, tanning method and irradiation conditions.

    2013-01-01

    Summary Although ultraviolet radiation (UV) exposure from indoor tanning has been linked to an increased risk of melanoma, the role of DNA repair genes in this process is unknown. We evaluated the association of 92 single nucleotide polymorphisms (SNPs) in 20 DNA repair genes with the risk of melanoma and indoor tanning among 929 melanoma patients and 817 controls from the Minnesota Skin Health Study. Significant associations with melanoma risk were identified for SNPs in ERCC4, ERCC6, RFC1, XPC, MGMT, and FBRSL1 genes; with a cut-off of p<0.05. ERCC6 and FBRSL1 gene variants and haplotypes interacted with indoor tanning. However, none of the 92 SNPs tested met the correction criteria for multiple comparisons. This study, based on an a priori interest in investigating the role of DNA repair capacity using variants in base excision and nucleotide excision repair, identified several genes that may play a role in resolving UV-induced DNA damage.

    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.

    Full Text Available O presente artigo de revisão centrou-se na prática desportiva e na sua relação com o bem-estar subjetivo e a integração social de imigrantes procurando fazer o levantamento da informação disponível na literatura acerca dessa temática a um nível mais global e, particularmente em Portugal, que a partir dos anos 80 se tornou num país de imigração. O levantamento bibliográfico incluiu livros, artigos científicos pesquisados em bases de dados internacionais, sites especializados e institucionais. A revisão da literatura permitiu verificar que: os imigrantes tendem a praticar menos desporto assim como a ter menores níveis de bem-estar subjetivo comparativamente à população autóctone; a prática desportiva relaciona-se positivamente com o bem-estar subjetivo também nos imigrantes; o desporto pode desempenhar um importante papel para a integração social dos imigrantes, apesar de nalguns contextos reforçar as diferenças inter-étnicas; em Portugal, não foram encontrados estudos específicos sobre a prática desportiva de imigrantes.

    Full Text Available En esta investigación el objetivo es analizar la capacidad predictiva de factores sociodemográficos y características personales sobre el bienestar subjetivo y psicológico en población mexicana. Los participantes fueron 976 adultos que cumplimentaron escalas de felicidad, satisfacción vital, emociones positivas y negativas, bienestar psicológico, los Cinco Grandes de personalidad, optimismo y autoestima. Los resultados indicaron que los factores sociodemográficos tenían un tamaño de efecto pequeño sobre las distintas dimensiones de bienestar subjetivo y psicológico. Los análisis de regresión múltiple mostraron que, tanto el bienestar subjetivo como el psicológico, eran explicados por alta extraversión, responsabilidad, autoestima y bajo neuroticismo. Estos resultados sugieren que, no solo los Cinco Grandes, sino la autoestima es un potente predictor de ambos tipos de bienestar en mayor medida que los factores sociodemográficos. Los descubrimientos son consistentes con los encontrados en otras culturas, aunque aparecen diferencias que son discutidas con relación a cómo abordarlas por parte de las autoridades mexicanas.

    The TanDEM-X mission will strive for generating a global precise Digital Elevation Model (DEM) by way of bi-static SAR in a close formation of the TerraSAR-X satellite, already launched on June 15, 2007, and the TanDEM-X satellite to be launched in May 2010. Both satellites carry the Tracking, Occultation and Ranging (TOR) payload supplied by the GFZ German Research Centre for Geosciences. The TOR consists of a high-precision dual-frequency GPS receiver, called Integrated GPS Occultation Receiver (IGOR), and a Laser retro-reflector (LRR) for precise orbit determination (POD) and atmospheric sounding. The IGOR is of vital importance for the TanDEM-X mission objectives as the millimeter level determination of the baseline or distance between the two spacecrafts is needed to derive meter level accurate DEMs. Within the TanDEM-X ground segment GFZ is responsible for the operational provision of precise baselines. For this GFZ uses two software chains, first its Earth Parameter and Orbit System (EPOS) software and second the BERNESE software, for backup purposes and quality control. In a concerted effort also the German Aerospace Center (DLR) generates precise baselines independently with a dedicated Kalman filter approach realized in its FRNS software. By the example of GRACE the generation of baselines with millimeter accuracy from on-board GPS data can be validated directly by way of comparing them to the intersatellite K-band range measurements. The K-band ranges are accurate down to the micrometer-level and therefore may be considered as truth. Both TanDEM-X baseline providers are able to generate GRACE baselines with sub-millimeter accuracy. By merging the independent baselines by GFZ and DLR, the accuracy can even be increased. The K-band validation however covers solely the along-track component as the K-band data measure just the distance between the two GRACE satellites. In addition they inhibit an un-known bias which must be modelled in the comparison, so the

    Full Text Available Este estudo teve por objetivo verificar o poder preditivo de características de personalidade e eventos de vida sobre o bem-estar subjetivo (BES. Participaram 274 universitários, 69% mulheres. Os resultados mostraram neuroticismo e extroversão como as principais variáveis explicativas do BES. Ainda, seis eventos de vida contribuíram com a explicação do BES, por exemplo, "término de namoro" mostrou-se variável preditiva positiva de Afeto positivo;"problemas financeiros" explicou negativamente a Satisfação de Vida. Os resultados sugerem que, embora as pessoas possam avaliar suas vidas como mais positivas e experienciar afetos mais positivos em função de suas características de personalidade, é pertinente adotar no campo de estudos do BES uma abordagem interacionista, integrando fatores intrínsecos, como personalidade, e extrínsecos, como eventos de vida.

    Evidence indicates that tanning may be addictive and is associated with other behavioral health conditions. Few studies have examined tanning addiction among adolescents. We performed a cross-sectional study to explore the relationship between tanning addiction, substance use, and psychological conditions among ethnoracially diverse 16-17 year-olds. Tanning addiction was assessed using the modified (m) CAGE measure among 11 th grade students in Los Angeles (N=2,637; response rate 78%). Overall, 7.02% of the sample met tanning addiction criteria. Tanning addiction was significantly associated with past 30-day smoking and marijuana use, problem substance use, depression, panic disorder, obsessive compulsive disorder (OCD), and bipolar disorder in regression models. After controlling for all significant substance use and psychological variables, problem marijuana use and OCD remained significantly associated with tanning addiction (odds ratio 2.06, 95% confidence interval 1.03-4.09; and 2.54, 1.73-3.72, respectively.) Tanning addiction was also significantly associated with multiple problem substance use and behavioral health conditions. Our findings indicate an appreciable prevalence of tanning addiction among multiethnic adolescents, and suggest the importance of addressing tanning addiction in the context of comorbid behavioral conditions to reduce this high-risk behavior among diverse youth.

    Nearly 30 million people tan indoors in the United States annually, including 2.3 million adolescents. Despite increased evidence on the dangers of artificial UV radiation, the popularity of indoor tanning is growing. We aim to assess the following 3 entities: (1) the association of indoor tanning with skin cancer; (2) statements regarding the health benefits of indoor tanning, especially regarding the production of vitamin D; and (3) current regulation of the tanning industry in the United States. We conducted a narrative review of the literature. Indoor tanning poses great risks. Studies support the role of artificial UV radiation in cutaneous carcinogenesis. Despite claims by the tanning industry, artificial tanning is not a safe or necessary way to increase systemic vitamin D levels. The National Institutes of Health and the World Health Organization have acknowledged the risks of indoor tanning. Nonetheless, regulations limiting tanning in the United States are surprisingly sparse. Systematic review of the literature was not performed. Health care providers must increase efforts to warn and educate the public and government about the dangers of UV radiation.

    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. To empirically assess the links between media use, indoor tanning-related outcome expectations, and behavioral intentions. 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. 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. 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. These findings highlight the social nature of adolescent females and point to specific intervention channels for reducing indoor tanning among this population.

  18. An in vivo evaluation of surface polishing of TAN intermedullary nails for ease of removal

    Full Text Available Fractures of the tibia and femoral diaphysis are commonly repaired by intra-medullary (IM nailing. Currently IM nails are available in either electropolished stainless steel (SS or in Titanium-Aluminium-Niobium (TAN. After healing, removal of the nails still is common but removal of TAN IM nails often has complications whereas SS IM nails of the same design are less often associated with problems. We believe the differences in removal are due to the ability of TAN to promote strong bone on-growth. We have previously shown in vivo that polishing cortical screws reduces removal torque and the percentage of bone-implant contact. Therefore, we postulate that bony on-growth onto IM nails can be reduced by means of surface polishing, for ease of removal. Here we aim to compare the pull-out forces for removal of standard TAN (TAN-S compared to experimental paste polished TAN (TAN-PP IM nails from a bilateral non-fracture sheep tibia model after 12 months implantation. Histological analysis was also performed to assess tissue on-growth to the nails. We show that polishing significantly reduces (p=0.05 the extraction force required for TAN IM nail removal. This effect in part is attributable to the distinct tissue-material reaction produced. For TAN-S nails direct bone contact was observed while for TAN-PP nails a fibrous tissue interface was noted. Since TAN is preferred over SS for IM nailing due to superior biocompatibility and mechanical properties, we believe these findings could be used to recommend changes to current surface technologies of intramedullary nails to reduce complications seen with nail removal especially in rapidly growing bone in children.

    Full Text Available 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

    IMPORTANCE Indoor tanning is associated with an increased risk of skin cancer, including melanoma, and is particularly dangerous for younger and more frequent indoor tanners. OBJECTIVE To examine the prevalence of indoor tanning and frequent indoor tanning (≥10 times during the 12 months before each survey) and their association with health-related behaviors. DESIGN, SETTING, AND PARTICIPANTS A cross-sectional study examined data from the 2009 and 2011 national Youth Risk Behavior Surveys, which used nationally representative samples of US high school students representing approximately 15.5 million students each survey year. The study included 25 861 students who answered the indoor tanning question. MAIN OUTCOMES AND MEASURES The prevalence of indoor tanning and frequent indoor tanning were examined as well as their association with demographic characteristics and health-related behaviors using multivariable logistic regression modeling. RESULTS The prevalence of indoor tanning was greater among female, older, and non-Hispanic white students. Indoor tanning was highest among female students aged 18 years or older, with 31.5% engaging in indoor tanning in 2011, and among non-Hispanic white female students, with 29.3% engaging in indoor tanning in 2011. Among female students, the adjusted prevalence of indoor tanning decreased from 26.4% in 2009 to 20.7% in 2011. Among female and male students, indoor tanning was associated with other risk-taking behaviors, such as binge drinking (P < .001 and P = .006, respectively), unhealthy weight control practices (P < .001, for both), and having sexual intercourse (P < .001, for both). Additionally, indoor tanning among female students was associated with using illegal drugs (P < .001) and having sexual intercourse with 4 or more persons (P = .03); use among male students was associated with taking steroids without a physician’s prescription (P < .001), smoking cigarettes daily (P = .03), and attempting suicide (P = .006

    Internet search trends are used to track both infectious diseases and noncommunicable conditions. The authors sought to characterize Google Trends search volume index (SVI) for the terms "sunscreen" and tanning ("tanning salon" and "tanning bed") in the United States from 2010 to 2015 and analyze association with educational attainment, average income, and percent white data by state. SVI is search frequency data relative to total search volume. Analysis of variance, univariate, and multivariate analyses were performed to assess seasonal variations in SVI and the association of state-level SVI with state latitudes and census data. Hawaii had the highest SVI for sunscreen searches, whereas Alaska had the lowest. West Virginia had the highest SVI for tanning searches, whereas Hawaii had the lowest. There were significant differences between seasonal SVI for sunscreen and tanning searches (p trends for sunscreen and tanning are influenced by socioeconomic factors, and could be a tool for skin-related public health.

    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 magazines.

    Full Text Available According to European legislation, it is not possible to dump any chromium-containing waste in Europe. The minimization of wastes is a key element in that strategy. It involves the application of clean technologies: low and non-waste technologies. The tanning industry generates substantial quantities of chromium-containing solid waste in the form of shavings and trimmings. The recycling and reuse of those wastes must be the primary target in optimizing processes of the leather industry. The problem is in a satisfying chromium separation from collagen fibers. Common hydrolysis processes-alkaline or acidic-give gelatins containing residual chromium (III. By using an oxidation agent (H2O2 before alkaline hydrolysis, in was demonstrated that chromium from chromium-containing leather wastes can be almost fully recovered by the previous oxidation of Cr(III to Cr(VI. This chromium can be reused in the tanning process. That would represent an economic saving. The best result of the dechroming process was a gelatin hydrolyzate with only 1.11 in respect to the initial amount.

    Within the minimal supersymmetric standard model (MSSM), the large tan β regime can lead to important modifications in the pattern of CP-violating sources contributing to low energy electric dipole moments (EDMs). In particular, four-fermion CP-violating interactions induced by Higgs exchange should be accounted for alongside the constituent EDMs of quarks and electrons. To this end, we present a comprehensive analysis of three low energy EDM observables - namely the EDMs of thallium, mercury and the neutron - at large tan β, in terms of one- and two-loop contributions to the constituent EDMs and four-fermion interactions. We concentrate on the constrained MSSM as well as the MSSM with non-universal Higgs masses, and include the CP-violating phases of μ and A. Our results indicate that the atomic EDMs receive significant corrections from four-fermion operators, especially when Im(A) is the only CP-violating source, whereas the neutron EDM remains relatively insensitive to these effects. As a consequence, in a large portion of the parameter space, one cannot infer a separate bound on the electron EDM via the experimental constraint on the thallium EDM. Furthermore, we find that the electron EDM can be greatly reduced due to the destructive interference of one- and two-loop contributions with the latter being dominated by virtual staus. (orig.)

    Full Text Available Usually, beamhouse processes are carried out by varying a medium from strongly alkaline (unhairing-liming up to strongly acid (pickling. This study is designed to develop a preparation of hide for tanning via processes that avoid a sharp change of hide pH. Enzymes active in acid medium are employed for hide unhairing in a buffer system containing 2.5% acetic acid and 0.3% sodium acetate. An oxidative treatment with peracetic acid then allows the complete removal of residual hair and scud. During both processes, unhairing and oxidative treatment, the opening of the derma structure occurs: 13.3-14.6g of non-collagen proteins are removed and amount of dermatan sulphate decreases by 35%. The hide obtained can be chromed directly after the above processes and subsequent treatment with sodium chloride solution omitted conventional pickling. The pH of the hide varies in the range of 8.3-3.7 during the processes of preparation for tanning.

    Full Text Available Abstract Background Despite educational and public health campaigns to convey the risks of indoor tanning, many individuals around the world continue to engage in this behavior. Few descriptive studies of indoor tanning have collected information pertaining to the lifetime history of indoor tanning, thereby limiting our ability to understand indoor tanning patterns and potentially target interventions for individuals who not only initiate, but continue to persistently engage in indoor tanning. Methods In-person interviews elicited detailed retrospective information on lifetime history of indoor tanning among white individuals (n = 401 under age 40 seen by a dermatologist for a minor benign skin condition. These individuals were controls in a case-control study of early-onset basal cell carcinoma. Outcomes of interest included ever indoor tanning in both males and females, as well as persistent indoor tanning in females - defined as females over age 31 who tanned indoors at least once in the last three or all four of four specified age periods (ages 11-15, 16-20, 21-30 and 31 or older. Multivariate logistic regression was used to identify sociodemographic and lifestyle correlates of ever and persistent indoor tanning in females. Results Approximately three-quarters (73.3% of females and 38.3% of males ever tanned indoors, with a median age of initiation of 17.0 and 21.5, respectively. Among indoor tanners, 39.3% of females and 21.7% of males reported being burned while indoor tanning. Female ever indoor tanners were younger, had darker color eyes, and sunbathed more frequently than females who never tanned indoors. Using unique lifetime exposure data, 24.7% of female indoor tanners 31 and older persistently tanned indoors starting as teenagers. Female persistent indoor tanners drank significantly more alcohol, were less educated, had skin that tanned with prolonged sun exposure, and sunbathed outdoors more frequently than non-persistent tanners

    Full Text Available 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.

    To evaluate the effectiveness of InterTan in the treatment of femoral intertrochanteric fractures. Between April 2009 and July 2009, 57 patients with femoral intertrochanteric fracture were treated with InterTan. There were 33 males and 24 females with an average age of 68 years (range, 45-88 years). The locations were left side in 31 cases and right side in 26 cases and all fractures were closed fractures. According to Association for Osteosynthesis/Orthopaedic Trauma Association (AO/OTA) classification, there were 23 cases of type 31-A1, 27 of type 31-A2, and 7 of type 31-A3. The disease duration was 2 to 8 days with an average of 3.3 days. The data of operative time, blood loss, perioperative blood transfusion, hospitalization day, fracture healing time, and Harris hip score were recorded. The operative time and the blood loss were (74.5 +/- 19.7) minutes and (148.8 +/- 79.6) mL, respectively. There were significant differences in the operative time and the blood loss among the AO/OTA subgroups (P blood transfusion and the transfusion volume was (264.0 +/- 90.7) mL. The average hospitalization days were 7 days (range, 6-9 days). Thirty-five patients were followed up 12 to 15 months (13.3 months on average). X-ray films showed that all fractures healed within (2.8 +/- 0.8) months. The healing time of fracture was (2.4 +/- 0.6), (2.9 +/- 0.9), and (3.8 +/- 0.5) months in 31-A1 subgroup, 31-A2 subgroup, and 31-A3 subgroup, respectively. There was no significant difference in healing time of fracture between 31-A1 subgroup and 31-A2 subgroup (P > 0.05), and there were significant differences between 31-A3 group and 31-A1 subgroup, 31-A2 subgroup (P < 0.05). No shortening, cut-out, varus malposition, femoral shaft fracture, or implant failures was found. The Harris score at the final follow-up was 84.5 +/- 8.2 with an excellent and good rate of 80% (15 cases of excellent, 13 of good, 6 of fair, and 1 of poor).

    The Initial Engine Test (IET) facility is located on the Idaho National Engineering Laboratory (INEL) site at the north end of Test Area North (TAN). The IET facility was constructed and used for the Aircraft Nuclear Propulsion Program during the 1950's and was later used for two other programs: the Space Nuclear Auxiliary Power Transient (SNAP-TRAN) and the Hallam Decontamination and Decommissioning Project. The facility is no longer in use, therefore, a complete radiological characterization was conducted at the IET site. The characterization included measurements of beta-gamma dose rates; beta-gamma and alpha surface contamination; concentrations of selected radionuclides in subsurface storage tanks, surface soil, the exhaust duct, stack and test pad; and a walk-over surface survey of the entire facility. The information contained in this report will be of great value as the IET facility goes through the decommissioning and decontamination process.

    High spatial resolution X-band interferometric SAR data from TanDEM-X acquired in the operational DEM generation mode are sensitive to forest structure and can therefore be used for thematic boreal forest classification. The interferometric coherence in absence of temporal decorrelation depends strongly on forest height and structure. Due to the rather homogenous structure of boreal forest, forest biomass can be derived from forest height, on the basis of allometric equations with sufficient accuracy and can therefore, be used for thematic classification applications. Two test sites in mid- and southern Sweden are investigated. A maximum of 4 biomass classes, up to 150 Mg/ha, for a single baseline scenario and 5 biomass classes up to 250 Mg/ha for a dual baseline scenario, are achieved.

    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. PMID:23947671

    Full Text Available Background. Sun-tanning perceptions are monitored to identify changes and help refine targeting of skin cancer prevention messages. Aim. To investigate associations between perceptions of sun-tanning and demographic factors among a New Zealand urban population, 1994–2006. Methods. A telephone survey series was conducted during summer in 1994, 1997, 1999/2000, 2002/2003, and 2005/2006. Demographic and personal information (sex, age group, skin sun-sensitivity, and self-defined ethnicity obtained from 6,195 respondents, 50.2% female, 15–69 years, was investigated in relation to six sun-tanning related statements. A total “positive perceptions of tanning” (ProTan score was also calculated. Regression analyses modelled each component and the ProTan score against survey year and respondent characteristics. Results. Statistically significantly higher ProTan scores were found for age group (strong reverse dose-response effect, male sex, residence (highest in Auckland, ethnicity (highest among Europeans, and sun sensitivity (an n-shaped association. There was no statistically significant change in total ProTan scores from baseline. Conclusions. The development, pretesting, and evaluation of messages for those groups most likely to endorse ProTan statements should be considered for the New Zealand skin cancer prevention program. To achieve and embed significant change, mass media campaigns may require greater intensity and reinforcement with sustained contextual support for settings-based behavioural change.

    TAN (triacetoneamine-N-oxyl) at a concentration of 10 mM gives a dose modifying factor (DMF) of 1.45 for the surviving fraction of gamma-irradiated hypoxic mammalian cells. Under the same conditions, however, TAN produces little or no enhancement of single strand breaks (SSB) in DNA (DMF congruent to 1). In this study, enhancement of the type of DNA lesions exposed by an extract of M. luteus is reported. The DMF for this type of damage (MLS) is 1.5. TAN is known to affect the size of DNA synthesized after irradiation, presumably by causing interruptions in synthesis at TAN-DNA adduct sites. The absolute number of M. luteus extract sensitive sites detected in this work corresponds to approximately on half of the number of sites of interrupted synthesis. In its sensitizing effect on DNA, the free radical TAN is different from the electron affinic drug, misonidazole.

    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.

    Full Text Available En un mundo tan complejo, los medios de comunicación son las fuentes de información fundamentales. La calidad de la información que éstos nos ofrecen va a determinar nuestra visión del mundo. Sin embargo, los medios de comunicación siguen siendo banalizados y mal entendidos. Tampoco existen organismos que fiscalicen la calidad de la información internacional. Cuando se piensa en cómo prevenir o solucionar una crisis, rara vez se toma en cuenta la calidad de la información y el cubrimiento de los medios. Pero es fundamental que cambiemos esta concepción. Sólo con base en una sólida visión del conflicto desde la economía política y desde la historia pueden evitarse las interpretaciones culturales facilistas.

  10. The potential carcinogenic risk of tanning beds: clinical guidelines and patient safety advice

    International Nuclear Information System (INIS)

    Mogensen, Mette; Jemec, Gregor BE

    2010-01-01

    In 2009, the WHO listed ultraviolet (UV) radiation as a group 1 carcinogen. In spite of this, each year, millions of people tan indoor in Western countries. The aim of this review is to summarize evidence of tanning bed carcinogenesis and to present guidelines for use of tanning beds and patient safety advice. A narrative review of the literature was conducted based on both PubMed and Medline searches and on literature review of the retrieved papers. Use of indoor tanning beds represents a significant and avoidable risk factor for the development of both melanoma and nonmelanoma skin cancers. Frequent tanners are more often adolescent females. Tanning beds have additional potential adverse effects such as burns, solar skin damage, infection, and possibly also addictive behavior. The effort in preventing UV light-induced carcinogenesis should currently be aimed at developing new strategies for public health information. Tanning beds are one preventable source of UV radiation. In the majority of people solar UV radiation continues to be the major factor and therefore anti-tanning campaigns must always include sunbathers

    Research suggests that youth proximity to tanning salons may promote use; however, little is known about tanning salon proximity to schools. We assessed the proximity of tanning salons to schools in urban versus rural/suburban communities across Worcester County, Massachusetts (population > 800K). To put findings in context, we compared school proximity to tanning salons to school proximity to McDonald's restaurants, a large franchise that also caters to young people. Accessibility was measured by ArcGIS 10.2 Network Analyzer (ESRI, Redlands, CA, USA) and the most current road network data layer from Massachusetts Department of Transportation (MassDOT). A total of 145 schools were observed in the study area, of which about 39% of schools were within 1 mile from a tanning salon. Urban schools (53.41%) had a higher proportion within 1 mile of a tanning salon than rural/suburban schools (17.54%; P < .001). More schools (39.31%) were within 1 mile of a tanning salon than schools within 1 mile of a McDonald's (22.70%; P < .001). Schools may be particularly impactful for implementing skin cancer prevention programing. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    To examine the relationship between tanning and nevus development in very-light-skinned children. Prospective cohort nested within a randomized controlled trial. Skin examinations in 3 consecutive years (2004, 2005, and 2006) included full-body counts of nevi, skin color and tanning measurement using colorimetry, and hair and eye color evaluation by comparison with charts. Telephone interviews of parents provided sun exposure, sun protection, and sunburn history. Large managed-care organization and private pediatric offices in the Denver, Colorado, metropolitan area. A total of 131 very-light-skinned white children without red hair and 444 darker-skinned white children without red hair born in Colorado in 1998. Full-body nevus counts at ages 6 to 8 years. Among very-light-skinned white children, geometric mean numbers of nevi for minimally tanned children were 14.8 at age 6 years; 18.8 at age 7 years; and 22.3 at age 8 years. Mean numbers of nevi for tanned children were 21.2 at age 6 years; 27.9 at age 7 years; and 31.9 at age 8 years. Differences in nevus counts between untanned and tanned children were statistically significant at all ages (P hair and eye color, parent-reported sun exposure, and skin phototype. Among darker-skinned white children, there was no relationship between tanning and nevi. Very-light-skinned children who tan (based on objective measurement) develop more nevi than children who do not tan. These results suggest that light-skinned children who develop tans may be increasing their risk for developing melanoma later in life.

  14. Human quadrupeds, primate quadrupedalism, and Uner Tan Syndrome.

    Directory of Open Access Journals (Sweden)

    Liza J Shapiro

    Full Text Available Since 2005, an extensive literature documents individuals from several families afflicted with "Uner Tan Syndrome (UTS," a condition that in its most extreme form is characterized by cerebellar hypoplasia, loss of balance and coordination, impaired cognitive abilities, and habitual quadrupedal gait on hands and feet. 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.

    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. 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. 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. The first dyad was enrolled on March 31, 2016, and we anticipate completing this study by October 2019

    Indoor tanning and sunburns, particularly during adolescence and young adulthood, increase the risk of developing skin cancer. To examine the trends in the prevalence of indoor tanning and the association between indoor tanning and sunburn among US high school students. This study pooled and examined cross-sectional data from the 2009, 2011, 2013, and 2015 national Youth Risk Behavior Survey. During 2009, 2011, 2013, and 2015, the overall response rates were 71%, 71%, 68%, and 60%, respectively, and unweighted sample sizes were 16 410, 15 425, 13 538, and 15 624, respectively. It included nationally representative samples of US high school students. Data were collected during the spring semester (January to June) in each survey cycle beginning February 9, 2009, through June 18, 2015. Prevalence of indoor tanning in the past year from 2009 to 2015 and its association with sunburn in 2015. Among high school students in the United States, the prevalence of indoor tanning decreased from 15.6% (95% CI, 13.7%-17.6%) in 2009 to 7.3% (95% CI, 6.0%-8.9%) in 2015. Decreases in indoor tanning were found among male (from 6.7% in 2009 to 4.0% in 2015) and female (from 25.4 % in 2009 to 10.6 % in 2015) students overall, non-Hispanic white (from 21.1 % in 2009 to 9.4% in 2015) and Hispanic (from 8.2% in 2009 to 4.7% in 2015) students overall, and all age groups. Among non-Hispanic white female students, the prevalence decreased from 37.4% (95% CI, 33.6%-41.4%) in 2009 to 15.2% (95% CI, 11.7%-19.5%) in 2015. In 2015, indoor tanning was associated with sunburn in the adjusted model: 82.3% (95% CI, 77.9%-86.0%) of indoor tanners had at least 1 sunburn during the preceding year compared with 53.7% (95% CI, 48.9%-58.4%) of those who did not engage in indoor tanning (P < .001). Despite declines in the prevalence of indoor tanning from 2009 to 2015 among high school students nationwide, indoor tanning remains commonplace among certain subgroups, especially non-Hispanic white female

    We investigated the interactions between selected organic tanning agents and type I fibrillar collagen as a model fibrillar substrate to enable the fast direct evaluation and validation of interpretations of tanning activity. Type I fibrillar collagen (1%) as gel was used as substrate of tanning and tannic acid, resorcinol- and melamine-formaldehyde and their combination at three concentrations as crosslinking agents (tannins). To evaluate the stability of collagen during tanning, the crosslinked gels at 2.8, 4.5 and 9.0 pHs were freeze-dried as discs which were characterized by FTIR, shrinkage temperature, enzymatic degradation and optical microscopy, and the results were validated by statistical analyses. The best stability was given by combinations between resorcinol- and melamine-formaldehyde at isoelectric pH.

    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.

    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.

    Despite Ireland's temperate maritime climate, it has the third highest rate of malignant melanoma in the European Union, indicating the need to recognise tanning practices as a risky behaviour, especially amongst those most at risk (the younger population). To explore the factors associated with deliberate sun tanning amongst university students in Cork, Ireland. Self-reported sun exposure, attitudes to tanning and sun protection practices were investigated using an online questionnaire in April 2010. There were 833 responses (8.33 %), mean age 22 years, 75 % female. Reporting deliberate tanning in the previous summer (n = 389, 46.7 %) was positively correlated (r = 0.622, p students were significantly more likely to report these attitudes; being a current smoker was associated with reporting peer pressure and that burning is worth a tan, indicating a level of risk-taking. Respondents reported (average) three sources of information on sun risks. Tanning is a form of strongly motivated risk-taking as much in a sun-limited country like Ireland as in hotter sun-rich climates. Risk communication strategies on sun exposure should be developed that target young people and improve their risk awareness.

    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.

    The ratio of neutral Higgs field vacuum expectation values, tan beta , is one of the most important parameters to determine in either the minimal supersymmetric standard model (MSSM) or a general type-II two-Higgs doublet model (2HDM). Assuming an energy and integrated luminosity of square root s=500 GeV and L=2000 fb/sup -1/ at a future linear collider (LC), we show that a very accurate determination of tan beta will be possible for low and high tan beta values by measuring the production rates of Higgs bosons and reconstructing Higgs boson decays. In particular, based on a TESLA simulation, and assuming no other light Higgs bosons and 100tan beta at high tan beta . In the MSSM Higgs sector, in the sample case of m/sub A/=200 GeV, we find that the rates for e/sup +/e/sup -/ to bbA+bbH to bbbb and for e/sup +/e/sup -/ to HA to bbbb provide a good determination of tan beta at hi...

    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. © 2011 The Authors.

    Indoor tanning is associated with an increased risk of melanoma. The US Food and Drug Administration proposed prohibiting indoor tanning among minors younger than 18 years. We sought to estimate the health and economic benefits of reducing indoor tanning in the United States. We used a Markov model to estimate the expected number of melanoma cases and deaths averted, life-years saved, and melanoma treatment costs saved by reducing indoor tanning. We examined 5 scenarios: restricting indoor tanning among minors younger than 18 years, and reducing the prevalence by 20%, 50%, 80%, and 100%. Restricting indoor tanning among minors younger than 18 years was estimated to prevent 61,839 melanoma cases, prevent 6735 melanoma deaths, and save $342.9 million in treatment costs over the lifetime of the 61.2 million youth age 14 years or younger in the United States. The estimated health and economic benefits increased as indoor tanning was further reduced. Limitations include the reliance on available data and not examining compliance to indoor tanning laws. Reducing indoor tanning has the potential to reduce melanoma incidence, mortality, and treatment costs. These findings help quantify and underscore the importance of continued efforts to reduce indoor tanning and prevent melanoma. Published by Elsevier Inc.

    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.

    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.

    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.

    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.

    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.

    Indoor tanning by adults under 35 years of age increases the risk of developing melanoma 59% to 75%. Cost is a major barrier limiting young adults from purchasing indoor tanning services. Our recent study by Boyers et al determined that 18 of 96 major universities, all in the eastern and southern United States, had university-sponsored debit cards with indoor tanning affiliations. These debit cards, which conveniently link with student identification (ID) cards, help with student living expenses and are often loaded with money by parents. By creating agreements with indoor tanning salon vendors, universities are endorsing a World Health Organization class I carcinogen. To expand the results of our previous study, we broadened our search to further assess universities in the western United States as well as Australia, New Zealand, Ireland, Canada, and the United Kingdom. Using www.collegeboard.edu, we identified the 4 largest residential colleges in Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington, and Wyoming. Additionally, we investigated the top international universities, utilizing www.topuniversities.com. Internet searches, phone calls, and email correspondence were used to determine if an institution had a student ID-linked debit card. Universities with affiliations to bank debit cards and cards that could only be used on campus were excluded. In the western United States, indoor tanning merchants were affiliated with University of Arizona, Embry-Riddle Aeronautical University: Prescott Campus, and the University of Denver student debit cards. Of the original 18 schools with affiliations according to the Boyers et al study, 2 universities no longer have agreements and 5 created agreements with additional tanning salons. Of 45 universities examined in our international search, no debit cards were discovered for off-campus purchases. Therefore, the concerning issue of university associations with tanning salons appears

    The opposite signs of the temperature coefficient of resistance (TCR) of two thin film materials, titanium nitride (TiN) and tantalum nitride (TaN), were used to form temperature compensated thin film resistors (TFRs). The principle of designing temperature compensated TFRs by connecting TFRs of each compound in series or in parallel was demonstrated. TiN, TaN, and combined TiN and TaN TFRs for monolithic microwave integrated circuits (MMICs) were fabricated by reactive sputtering. DC characterization was performed over the temperature range of 30–200 °C. The TiN TFRs exhibited an increase in resistivity with temperature with TCRs of 540 and 750 ppm/°C. The TaN TFR on the other hand exhibited a negative TCR of − 470 ppm/°C. The shunted TFRs were fabricated by serial deposition of TiN and TaN to form a bilayer component. The TCRs of the series- and shunt configurations were experimentally reduced to − 60 and 100 ppm/°C, respectively. The concept of temperature compensation was used to build a Wheatstone bridge with an application in on-chip temperature sensing.

    The incidence of skin cancer is rising in the U.S., and melanoma, the deadliest form, is increasing disproportionately among young white women. Indoor tanning is a modifiable risk factor for all skin cancers and continues to be used at the highest rates in young white women. Adolescents and young adults report personal appearance–based reasons for using indoor tanning. Previous research has explored the influences on tanning bed use, including individual factors as well as relationships with peers, family, schools, media influences, legislation, and societal beauty norms. Adolescents and young adults also have high rates of social media usage, and research is emerging on how best to utilize these platforms for prevention. Social media has the potential to be a cost-effective way to reach large numbers of young people and target messages at characteristics of specific audiences. Recent prevention efforts have shown that comprehensive prevention campaigns that include technology and social media are promising in reducing rates of indoor tanning among young adults. This review examines the literature on psychosocial influences on indoor tanning among adolescents and young adults, and highlights ways in which technology and social media can be used for prevention efforts.

    Ultraviolet (UV) radiation is a human carcinogen and is associated with the development of skin cancer. The promotion of indoor tanning (IT) at fitness centres is of particular concern as it reinforces the idea that a tan is associated with health and fitness. The purpose of this study was to investigate the prevalence of IT in fitness centres, with an emphasis on determining the financial costs, adherence to regulations, and safety precautions. Ten cities, representing 9 different Canadian provinces, were chosen for the study. From each province, a minimum of 20 and a maximum of 30 fitness centres were randomly selected from the Yellow Pages website. Each fitness centre was contacted by the principal investigator and inquiries were made from a consumer's perspective. Of the 203 gyms surveyed, 43% (88/203) offered tanning facilities. Of these, 10.23% (9/88) were found to be noncompliant with the provincial IT regulations for age and/or time between tanning sessions. Despite the known risks of IT, not all fitness centres are compliant with provincial legislations regarding IT, and some continue to promote tanning access to minors.

    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. PMID:1456348

    Full Text Available Some applications for products obtained by chromium chip alkaline hydrolysis produced during leather tanning were evaluated in this work, considering the concept of maximising tanneries’ solid residue reuse for different industrial applications and minimising the environmental impact so produced. When Cr(OH is transformed into Cr (OH(SO it can be used in tanning leather (i.e. as tanning salt. When compared to commercial salts, 2 4 it was determined that it could be applied to mixtures containing this salt, replacing it by up to 40%. Chromium content reduction was evaluated for collagen hydrolyzate by pH control after alkaline hydrolysis of the chips and by applying adsorbent materials such as bentonite, alfalfa and sorghum biomass and activated charcoal, a maximum 55% Cr removal being obtained when the first two adsorbent materials were used.

    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.

    Skin cancer is a significant public health problem among Canadians. Knowledge and attitudes about health are informed by mass media. The aim of our study was to describe the volume and nature of coverage of skin cancer and recreational tanning in Canadian women's magazines. Directed content analysis on article text and images in six popular Canadian women's magazines (Chatelaine, Canadian Living, Homemakers, Flare, FASHION, ELLE Canada) from 2000-2012 with attention to risk factors, ultraviolet radiation (UV) exposure and protection behaviours, and early detection. Six popular American women's magazines were used for a between-country comparison. There were 154 articles (221 images) about skin cancer and tanning published over 13 years. Volume of coverage did not increase in a linear fashion over time. The most common risk factor reported on was UV exposure (39%), with other risk factors less frequently identified. Although 72% of articles promoted sunscreen use, little content encouraged other protection behaviours. Only 15% of articles and 1% of images discouraged indoor tanning, while 41% of articles and 53% of images promoted the tanned look as attractive. Few articles (<11%) reported on early detection. Relative to American magazines, Canadian magazines had a greater proportion of content that encouraged sunscreen use and promoted the tanned look and a lesser proportion of content on risk factors and early detection. Skin cancer and tanning messages in Canadian women's magazines had a narrow focus and provided limited information on risk factors or screening. Conflicting messages about prevention (text vs. images) may contribute to harmful UV behaviours among Canadian women.

    Full Text Available 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.

    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.

    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.

    Click chemistry approaches are tailored to generate molecular building blocks quickly and reliably by joining small units together selectively and covalently, stably and irreversibly. The vegetable tannins such as hydrolyzable and condensed tannins are capable to produce rather stable radicals or inhibit the progress of radicals and are prone to oxidations such as photo and auto-oxidation, and their anti-oxidant nature is well known. A lot remains to be done to understand the extent of the variation of leather stability, color variation (lightening and darkening reaction of leather), and poor resistance to water uptake for prolonged periods. In the present study, we have reported click chemistry approaches to accelerated vegetable tanning processes based on periodates catalyzed formation of oxidized hydrolysable and condensed tannins for high exhaustion with improved properties. The distribution of oxidized vegetable tannin, the thermal stability such as shrinkage temperature (T s) and denaturation temperature (T d), resistance to collagenolytic activities, and organoleptic properties of tanned leather as well as the evaluations of eco-friendly characteristics were investigated. Scanning electron microscopic analysis indicates the cross section of tightness of the leather. Differential scanning calorimetric analysis shows that the T d of leather is more than that of vegetable tanned or equal to aldehyde tanned one. The leathers exhibited fullness, softness, good color, and general appearance when compared to non-oxidized vegetable tannin. The developed process benefits from significant reduction in total solids and better biodegradability in the effluent, compared to non-oxidized vegetable tannins.

    Full Text Available To explore how Chinese Buddhists acted as trailblazers of Engaged Buddhism, I shall analyze a late nineteenth-century thinker, Tan Sitong 譚嗣同 (1865–1898. The focus of my analysis is his masterpiece, Renxue 仁學. From his position of Buddhist eclecticism, Tan discoursed at length on non-differentiation as the truth of the universe to reflect on the creative disposition of human agency. He described in Renxue how this disposition would contribute to the agendas defining Chinese modernity. In addition, discussing the meanings of non-differentiation, Tan also generalized about the nature of the human agency he attempted to advocate: while he perceived the human agency blessed with a non-differentiating mindset as an omnipotent history-making force, he also argued that it did not confer upon its owner the status of world savior. In fact, in his view, the efficacy of a non-differentiating mind was determined by the world it aimed to help. Tan's signature piece, I argue, provides a lens through which we can observe modern Chinese Buddhism's role as an important part of the global formation of Engaged Buddhism.

    Full Text Available Chemical composition and physicochemical and mechanical parameters of New Zealand White rabbit tanned skin were evaluated. Skin samples from 70-d-old males, in natura and semi-finished, were collected for evaluation. The in natura treatment comprise skins without any processing, while semi-finished treatment comprise skins after soaking, fleshing, liming, de-liming, purging, degreasing, pickling, tanning, neutralising, re-tanning and dyeing, followed by oiling, drying, stretching and softening. After tanning, samples from the dorsal and flank regions were removed for tensile and physicochemical testing in the longitudinal and transverse directions. A split plot design was used with plot treatments (leather regions: R1=dorsal and R2=flank and subplots directions (S1=longitudinal and S2=transversal, using 10 examples per treatment. At the end of processing, the leather analysis revealed low moisture (31.76%, protein (46.48% and fat content (24.95%, and a high ash content (8.58%. Leather presented a pH of 4.9 and contained 2.0% chromium oxide, 25.5% extractable substances in dichloromethane, and these characteristics were coupled with a higher tensile strength (10.84 N/mm2 in the dorsal region. However, samples in the same region proved to have higher elasticity (64.57% in the longitudinal direction, although there was no difference in the progressive tearing analysis (21.07-23.50 N/mm. Overall, our analyses suggest that, in this case, the tanned leather product does not have sufficient resistance for application in clothing production.

    The primary goal of the German TanDEM-X mission is the generation of a highly accurate and global Digital Elevation Model (DEM) with global accuracies of at least 10 m absolute height error (linear 90% error). The global TanDEM-X DEM acquired with single-pass SAR interferometry was finished in September 2016. This paper provides a unique accuracy assessment of the final TanDEM-X global DEM using two different GPS point reference data sets, which are distributed across all continents, to fully characterize the absolute height error. Firstly, the absolute vertical accuracy is examined by about three million globally distributed kinematic GPS (KGPS) points derived from 19 KGPS tracks covering a total length of about 66,000 km. Secondly, a comparison is performed with more than 23,000 "GPS on Bench Marks" (GPS-on-BM) points provided by the US National Geodetic Survey (NGS) scattered across 14 different land cover types of the US National Land Cover Data base (NLCD). Both GPS comparisons prove an absolute vertical mean error of TanDEM-X DEM smaller than ±0.20 m, a Root Means Square Error (RMSE) smaller than 1.4 m and an excellent absolute 90% linear height error below 2 m. The RMSE values are sensitive to land cover types. For low vegetation the RMSE is ±1.1 m, whereas it is slightly higher for developed areas (±1.4 m) and for forests (±1.8 m). This validation confirms an outstanding absolute height error at 90% confidence level of the global TanDEM-X DEM outperforming the requirement by a factor of five. Due to its extensive and globally distributed reference data sets, this study is of considerable interests for scientific and commercial applications.

    Full Text Available The formation of the Ifninan-Tan margin started during the Triassic-Liassic extensional event, and continued during the Jurassic to present opening of the central Atlantic. This margin is located to the S of the South-Atlas lineament, between two contrasted geotectonic scenarios: the N, where the effect of the atlasic and alpine tectonics is spectacular, and the S, where this does not occur. The Ifninan-Tan margin is characterized by a series of post-rift deposits only slightly deformed and disturbed by salt diapirism towards the ocean. These series completely mask the structures of the rift, and they have been studied with the abundant information gathered by the oil exploration campaigns (seismic reflection and drilling, and with the analysis of gravimetrical and magnetic field-potential data. The study of the rift structures (both inland and offshore, highlights the difference between two sectors of the platform: (i a NE sector, where the upper part of the pre-rift substratum is not very deep, and where the dominating structural style is constituted by half-grabens and horsts; and, (ii a SW sector where grabens dominate. This paper shows that two structural styles and modes of extension can coexist on the same passive margin, one hundred kilometers apart. The differences described here are imposed by the structures inherited from the Hercynian evolution.La constitution de la marge Ifni/Tan-Tan a commencé lors de la distension triasico-liasique et s’est poursuivie pendant l’ouverture de l’Atlantique central, qui a eu lieu au Jurassique, jusqu’a l’actuel.

    Full Text Available A cross-sectional study of 120 subjects was performed with the purpose of evaluating stress hormones and emotional stress (anxiety in outpatient and hospitalized subjects. The aims were to determine the degree of objective stress, as well as to correlate this finding with subjective findings, estimated using Beck's Anxiety Inventory.. METHOD: Three populations were investigated, namely outpatient clinical cases (Group I, n = 30, hospitalized clinical individuals (Group II, n = 30, and hospitalized surgical candidates (Group III, n = 30. Controls (Group IV, n = 30 were healthy volunteers who were health-care professionals and students. To avoid hormone interactions, only men were enrolled in all groups. All hospitalized subjects were tested on admission and before therapeutic interventions. Fasting epinephrine, norepinephrine, and cortisol were measured in the morning, and Beck's Anxiety Inventory was adminstered by a trained psychologist. RESULTS: The 3 patient groups displayed higher anxiety levels than the controls. Hormone concentrations did not present remarkable changes and did not correlate with subjective stress (anxiety. CONCLUSIONS: 1 Subjective disorders (as determined with Beck's Anxiety Inventory were a common finding in both outpatient and hospitalized populations, without differences between the various groups; 2 Objective stress (as determined by elevated hormone levels was more difficult to confirm-findings rarely exceeded the reference range; 3 Correlation between the two variables could not be demonstrated; 4 Further studies are necessary to define stress quantification and interpretation in patient populations, especially in relationship with nutritional diagnosis and dietetic prescription.Um estudo transversal de 120 indivíduos foi executado visando avaliar hormônios do estresse e estresse subjetivo (ansiedade em casos ambulatoriais e hospitalizados.

    CP violation in neutral Higgs-boson exchange is studied in two-doublet models in an expansion in (1/tan 2 β). The typical magnitude of various CP-violating quantities is found for large tanβ. In particular the electric dipole moment (EDM) of the electron and the coefficient c S of the CP-violating electron-nucleon scalar-pseudoscalar operator are examined and it is found that in a simple class of two-doublet models c S /d e is typically O(tan 2 β). Therefore c S is more important than d e for the EDM's of diamagnetic atoms and molecules (Hg, Xe, TlF) typically if tanβ approx-gt 5, and for paramagnetic atoms (Cs, Tl) if tanβ approx-gt 15. The dependence on tanβ of the various contributions to the neutron EDM including the Weinberg three-gluon operator, and the dependence on tanβ of the top-quark EDM are also discussed. Supersymmetric and three-doublet models are also considered

    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. © The Author(s) 2014.

    Motives for UV exposure have been shown to be related to appearance concerns, yet little research has examined specific tan appearance attitudes. Given this lacuna, Study 1 involved the identification of six factors among college female tanners: general attractiveness, media influence, family/friends influence, physical fitness appearance, acne reasons, and skin aging concerns. In Study 2, a separate sample of college female tanners were used to validate a higher order factor model, which demonstrated acceptable fit. Additionally, the factors converged in the expected directions, with the general attractiveness and skin aging concerns being the best correlate of UV exposure and sun-protection intentions. The relevance of these findings to skin cancer prevention is discussed.

    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.

    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

    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

    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.

    Given the evidence for increased skin cancer risk due to the sunbed use, a regulation of hazardous artificial ultraviolet radiation (UVR regulation) was passed in Germany in 2012. The aim of this study was to explore the advisory services in tanning studios as reported by sunbed users and to evaluate the information provided by the personnel of tanning salons after the UVR regulation was enacted. The first wave of the representative National Cancer Aid Monitoring on Sunbed Use included a subgroup of 357 German citizens between 14 and 45 years who had used sunbeds since the UVR regulation was implemented. The participants provided data on sunbed use and related issues in telephone interviews. Although sunbed operators are mandated to offer their customers certain services at least once since the implementation of the UVR regulation, 15.4% of sunbed users were never advised to use protective eyewear during tanning and 13.1% were not provided with eyewear during their last sunbed use. Overall, 66.0% were never offered to develop a tanning schedule, 56.9% were never advised on the risks of UVR, 43.4% were never offered a determination of their skin type and 40.0% of users were never advised on how to use a sunbed safely. The data showed that 3 years after the UVR regulation was enacted, compliance with this legislation is still not optimal. Binding wording in the legal text and making them applicable to unsupervised sunbeds as well is necessary to extend the impact of this legislation. © 2017 John Wiley & Sons A/S.

    A subset of Drosophila neurons that expresses crustacean cardioactive peptide (CCAP) has been shown previously to make the hormone bursicon, which is required for cuticle tanning and wing expansion after eclosion. Here we present evidence that CCAP-expressing neurons (NCCAP) consist of two functionally distinct groups, one of which releases bursicon into the hemolymph and the other of which regulates its release. The first group, which we call NCCAP-c929, includes 14 bursicon-expressing neurons of the abdominal ganglion that lie within the expression pattern of the enhancer-trap line c929-Gal4. We show that suppression of activity within this group blocks bursicon release into the hemolymph together with tanning and wing expansion. The second group, which we call NCCAP-R, consists of NCCAP neurons outside the c929-Gal4 pattern. Because suppression of synaptic transmission and protein kinase A (PKA) activity throughout NCCAP, but not in NCCAP-c929, also blocks tanning and wing expansion, we conclude that neurotransmission and PKA are required in NCCAP-R to regulate bursicon secretion from NCCAP-c929. Enhancement of electrical activity in NCCAP-R by expression of the bacterial sodium channel NaChBac also blocks tanning and wing expansion and leads to depletion of bursicon from central processes. NaChBac expression in NCCAP-c929 is without effect, suggesting that the abdominal bursicon-secreting neurons are likely to be silent until stimulated to release the hormone. Our results suggest that NCCAP form an interacting neuronal network responsible for the regulation and release of bursicon and suggest a model in which PKA-mediated stimulation of inputs to normally quiescent bursicon-expressing neurons activates release of the hormone.

    While ultraviolet radiation (UVR) is a major cause of skin ageing and carcinogenesis, public pursuit of a novel tanning strategy circumventing the need for UVR is increasingly reported in the media and scientific press. This involves the subcutaneous self-administration of unregulated products labelled as melanotan I and/or II, synthetic analogues of α-melanocyte stimulating hormone (α-MSH), as obtained via the internet, tanning salons and gyms. The Medicines and Healthcare products Regulatory Authority has recently raised awareness of the public health risk of transmission of blood-borne viruses from the needle sharing that may occur, and of the potential impurity of these products. Dermatologists should also be aware that these agents can complicate the clinical presentation of patients with pigmented lesions; their use may be suspected in unexpectedly tanned individuals with rapidly pigmenting naevi. Meanwhile, the regulated α-MSH analogue afamelanotide (Clinuvel Pharmaceuticals Ltd, Melbourne, Australia) is showing promise for its photoprotective potential, and is undergoing phase II and III clinical trials in people with photosensitivity disorders and those prone to nonmelanoma skin cancer.

    The primary objective of the TanDEM-X mission is the generation of a global, consistent, and high-resolution digital elevation model (DEM) with unprecedented global accuracy. The goal is achieved by exploiting the interferometric capabilities of the two twin SAR satellites TerraSAR-X and TanDEM-X, which fly in a close orbit formation, acting as an X-band single-pass interferometer. Between December 2010 and early 2015 all land surfaces have been acquired at least twice, difficult terrain up to seven or eight times. The acquisition strategy, data processing, and DEM calibration and mosaicking have been systematically monitored and optimized throughout the entire mission duration, in order to fulfill the specification. The processing of all data has finally been completed in September 2016 and this paper reports on the final performance of the TanDEM-X global DEM and presents the acquisition and processing strategy which allowed to obtain the final DEM quality. The results confirm the outstanding global accuracy of the delivered product, which can be now utilized for both scientific and commercial applications.

    We match the Higgs sector of the most general flavour breaking and CP violating minimal supersymmetric standard model (MSSM) onto a generic two-Higgs-doublet model, paying special attention to the definition of tan beta in the effective theory. In particular no tan beta-enhanced loop corrections appear in the relation to tan beta defined in the DRbar scheme in the MSSM. The corrections to the Higgs-mediated flavour-changing amplitudes which result from this matching are especially relevant for the B_d and B_s mass differences dM_s,d for minimal flavour violation, where the superficially leading contribution vanishes. We give a symmetry argument to explain this cancellation and perform a systematic study of all Higgs-mediated effects, including Higgs loops. The corrections to dM_s are at most 7% for mu>0 and M_A tau^+ nu or B -> X_s gamma. We further update supersymmetric loop corrections to the Yukawa couplings, where we include all possible CP-violating phases and correct errors in the literature. The possi...

    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.

    The vegetable tannins are the oldest tanning agents used in leather industry. They give their natural character and colour to the leathers which they are applied to, but they have the disadvantage of colour change when they are exposed to light for prolonged times. In this study light fastness properties of leathers tanned with mimosa, quebracho, valonea and chestnut tannins were measured. Lightfastness properties of mimosa and quebracho tannins were found lower. Then these tannins were modif...

    Thick Ta(N) coating of 51 μm has been successfully obtained by DCMS technology. Ta(N) is a kind of distorted Ta matrix, which is inter-soluble with N-defect lattice structure, forming the disabled bcc structure. From the XRD and XPS investigations, the composition of Ta(N) coating is consisted of bcc-Ta and bcc-TaN0.06, while that of Ta coating mainly contains β-Ta phase. It can be concluded from wear test, nanoindentation test and SEM observations, wear resistance of Ta(N) coating is much better than that of Ta coating, due to its high hardness, H/E, H3/E2 value and low COF value. The wear mechanism of Ta coating is the compound fatigue and abrasive wear, while that of Ta(N) coating is transformed into adhesive wear mechanism. The secondary adhesion of the plastic deformation for the Ta(N) coating can reinforce the coated surface, to improve the load-bearing and anti-wear capacities, and thus improve the wear resistance.

    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

    Indoor tanning increases skin cancer risk. Beyond early research describing melanoma and sun lamps, few recent reports describe where individuals indoor tan and whether skin cancer risk varies by location (business, home-based). We sought to assess where individuals tanned indoors and skin cancer risk by tanning device location. Multivariate logistic regression was conducted in 2 US case-control studies of melanoma (1161 cases, 1083 controls, ages 25-59 years) and early-onset basal cell carcinoma (375 cases, 382 controls, agebasal cell carcinoma (odds ratio 1.69, 95% confidence interval 1.15-2.48) compared with non-users. Melanoma risk was also increased in the small number who reported tanning indoors only at home relative to non-users (odds ratio 4.14, 95% confidence interval 1.75-9.78); 67.6% used sun lamps. Self-reported tanning and potential recall bias are limitations. Business-only tanning, despite claims of "safe" tanning, was positively associated with a significant risk of melanoma and basal cell carcinoma. Home tanning was uncommon and mostly from sun lamps, which were rarely used by younger participants. Regardless of location, indoor tanning was associated with increased risk of skin cancer.

    Full Text Available 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.

    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. © 2016 British Association of Dermatologists.

    A multivariate standardization procedure was used to extend the lifetime of a multivariate partial least squares (PLS) calibration model for determining chromium in tanning sewage. The Kennard/Stone algorithm was used to select the transfer samples and the F-test was used to decide whether slope/bias correction (SBC) or piecewise direct standardization (PDS) had to be applied. Special attention was paid to the transfer samples since the process can be invalidated if samples are selected which behave anomalously. The results of the F-test were extremely sensitive to heterogeneity in the transfer set. In these cases, it should be taken as an interpretation tool.

    To present the differences in surgical technique of DSEK (Descemet's Stripping Endothelial Keratoplasty) with the use of Tan EndoGlide (Coronet, UK) and Busin Glide (Moria, FR). Short-term results will also be presented, DSEK was performed in 24 eyes, in 8 cases the surgery was combined with cataract phacoemulsification and lOL implantation. Surgery course and 6 months postoperative results of first 12 eyes performed with the use of Tan EndoGlide were compared with 12 consecutive eyes preformed with Busin Glide. Tan EndoGlide provided much more stable anterior chamber, donor tissue unfolding process was better controlled but the incision was wider incision. Surgically induced mean refractory cylinder 6. months after the surgery was 1.56 - 1.15 Dsph in Tan EndoGlide group and 1.18 +/- 1.10 Dsph in Busin Glide group (P 0.05). Mean CDVA was 0.65+/- 0.27 and 0.63 +/- 0.25, respectively (P>0,05). Statistically significant differences in intra- and post-operative complications between both groups were not found. The Tan EndoGlide used during posterior lamellar keratoplasty with DSEK technique is a good alternative to currently used methods. It provides better stabilization of the anterior chamber, however its use is linked with higher postoperative astigmatism in comparison with Busin Glide. The visual outcomes and endothelial cell loss 6 months after the surgery were similar in both groups.

    In recent years, the use of artificial tanning devices has become very popular in Chile. In April, 2007, a new law was established to regulate the non-medical use of tanning beds and tanning booths. The aim of this study was to evaluate the level and quality of information provided by tanning salon staff to clients before deciding on using the services. This information was collected before and 6 months after the law was enacted by researchers visiting tanning salons posing as potential clients. Using a previously designed questionnaire, 24 tanning salons in Santiago, Chile, were evaluated by researchers acting as potential customers without experience with artificial tanning devices. Employees were questioned using a hidden questionnaire before and 6 months after enactment of the law. Before the law, 25% of the establishments gave spontaneous information about the risks of using tanning beds, which increased to 45.8% after enactment of the law. Clients never received written information, either before or after enactment of the law. On both evaluations, more than 1/3 of the employees affirmed that there were no risks in using tanning beds. Before enactment of the law, only 12.5% of the tanning salons required the use of goggles, while after the law, this increased to 25% (P=NS). Only two establishments required that clients sign an informed consent form after enactment of the law. The level of knowledge among employees in tanning salons was very low and the quality of the information they provided to the clients was very poor. It was important to legislate on ultraviolet tanning services, but at present, the impact of the law has been very limited.

  3. Interferometric SAR Coherence Models for Characterization of Hemiboreal Forests Using TanDEM-X Data

    Full Text Available In this study, four models describing the interferometric coherence of the forest vegetation layer are proposed and compared with the TanDEM-X data. Our focus is on developing tools for hemiboreal forest height estimation from single-pol interferometric SAR measurements, suitable for wide area forest mapping with limited a priori information. The multi-temporal set of 19 TanDEM-X interferometric pairs and the 90th percentile forest height maps are derived from Airborne LiDAR Scanning (ALS, covering an area of 2211 ha of forests over Estonia. Three semi-empirical models along with the Random Volume over Ground (RVoG model are examined for applicable parameter ranges and model performance under various conditions for over 3000 forest stands. This study shows that all four models performed well in describing the relationship between forest height and interferometric coherence. Use of an advanced model with multiple parameters is not always justified when modeling the volume decorrelation in the boreal and hemiboreal forests. The proposed set of semi-empirical models, show higher robustness compared to a more advanced RVoG model under a range of seasonal and environmental conditions during data acquisition. We also examine the dynamic range of parameters that different models can take and propose optimal conditions for forest stand height inversion for operationally-feasible scenarios.

    This study aimed to determine the effect of syntan and mimosa combination on the quality of tanned red snapper leather. The study was designed using complete randomized design (CRD) and the advanced test of Least Significant Difference (LSD) with three replications and three treatments of combined syntan and mimosa, namely: p1 (4 % syntan, 5 % mimosa), p2 (8 % syntan, 5 %mimosa), p3 (12 % syntan, 5 % mimosa). Data were analyzed using SPSS 18. The measured parameters were tensile strength (N·cm-2), elongation (%), tear strength (N·cm-1), enervation (mm), wrinkle temperature (°C), fat/oil content (%) and water content (%). The results indicate that the combined syntan and mimosa tanners gave no significant effect on the physical parameters (tensile strength, elongation, tear strength, enervation and wrinkle temperature) and chemical parameters (moisture and fat/oil). All treatments (p1, p2 and p3) met the Indonesian National Standard (SNI) 06-4586-1998 for chrome tanned freshwater snake leather for the parameters of tensile strength, tear strength, enervation, wrinkle temperature and moisture. The parameter of elongation and fat/oil content did not meet with the SNI 06-4586-1998. Among the three combinations of a tanner, syntan 4 % and mimosa 5 % treatment gave the best leather quality.

  5. Electric dipole moments in the MSSM at large tanβ

    2004-01-01

    Within the minimal supersymmetric standard model (MSSM), the large tanβ regime can lead to important modifications in the pattern of CP-violating sources contributing to low energy electric dipole moments (EDMs). In particular, four-fermion CP-violating interactions induced by Higgs exchange should be accounted for alongside the constituent EDMs of quarks and electrons. To this end, we present a comprehensive analysis of three low energy EDM observables - namely the EDMs of thallium, mercury and the neutron - at large tanβ, in terms of one- and two-loop contributions to the constituent EDMs and four-fermion interactions. We concentrate on the constrained MSSM as well as the MSSM with non universal Higgs masses, and include the CP-violating phases of μ and A. Our results indicate that the atomic EDMs receive significant corrections from four-fermion operators, especially when Im(A) is the only CP-violating source, whereas the neutron EDM remains relatively insensitive to these effects. As a consequence, in a large portion of the parameter space, one cannot infer a separate bound on the electron EDM via the experimental constraint on the thallium EDM. Furthermore, we find that the electron EDM can be greatly reduced due to the destructive interference of one- and two-loop contributions with the latter being dominated by virtual status

    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.

    Due to land reclamation and dredging, 57% of China's coastal wetlands have disappeared since the 1950s, and the total area of tidal flats in South Korea decreased from approximately 2,800km2 in 1990 to 2392km2 in 2005(Qiu, 2011 and MLTM, 2010). Intertidal DEM and sedimentary facies are useful for understanding intertidal functions and monitoring their response to natural and anthropogenic actions. Highly accurate intertidal DEMs with 5-m resolution were generated based on the TanDEM-X interferometric SAR (InSAR) technique because TanDEM-X allows the acquisition of the coherent InSAR pairs with no time lag or approximately 10-second temporal baseline between master and slave SAR image. We successfully generated intertidal zone DEMs with 5-7-m spatial resolutions and interferometric height accuracies better than 0.15 m for three representative tidal flats on the west coast of the Korean Peninsula and one site of chinese coastal region in the Yellow Sea. Surface sediment classification based on remotely sensed data must circumspectly consider an effective critical grain size, water content, local topography, and intertidal structures. The earlier studies have some limitation that the classification map is not considered to analysis various environmental conditions. Therefore, the purpose of this study was minutely to mapping the surface sedimentary facies by analyzing the tidal channel, topography with multi-sensor remotely sensed data and in-situ data.

    Full Text Available The aim of this studies was characteristic of the sources of primary infection for tan spot. During the period 1998-1991 the development of ascomata and conidimata of Pyrenophora tritici-repentis on naturally infected wheat and triticale straws was monitored. The process of pseudothecia formation was extending over the time. It started immediately after harvest and protothecia of the fungus was commonly occurred each year already in the fall. The first fruit bodies with maturated typically pigmented ascospores were observed in January 2001 and in February 1998 and 1999. The percentage of pseudothecia with maturate ascospores successively increased richening maximum in April when the massive liberation of spores from asci occurred. After the total ascospore release on surface of empty ascomata aroused conidiophores with conidia which may also act as inoculum source. Moreover this type of sporulation was observed directly on over wintered cereals stems especially after prolonged period of rains. The present studies indicated also on infected by P.tritici-repentis wheat and triticale seeds as a source of inoculum for tan spot.

    Full Text Available Abstract: The migration of young Zapatistas to the United States as a geographic, political and subjective displacementThis article analyses how some young Zapa-tistas become international migrants that are put into global circuits of work under a capi-talist regime of flexible accumulation. It is argued that the migration of these young people represents a geographical, political and subjective displacement in which not only are they transported thousands of kilo-metres away from their towns, but they also experience a change in their subjectivities, their future perspectives and their life-time ambitions in comparison to previous genera-tions. It is shown that the migratory experi-ence of young Zapatistas is marked by ten-sion between periods of being practically unable to move to certain markets of work and certain geographic regions – particularly in agricultural California – and periods when, in contrast, they cannot establish themselves for any length of time in the same place, or continue in the same niche of work. In other words, their experiences have oscillated between periods in which they become a 'captive work force' that cannot move freely and periods when, in contrast, they become 'labour nomads' obligated to constant displacement and the impossibility of establishing themselves in the same place. These two situations are produced by the control over their 'illegalization' and represent the flip sides of the same coin. These two sides have as a consequence the extraction of cheap and hardworking labour; on the one hand they are prevented from moving, and on the other, from staying.Resumen:Este artículo analiza cómo algunos jóvenes zapatistas se convierten en migrantes inter-nacionales insertos en circuitos globales de trabajo bajo un régimen capitalista de acu-mulación flexible.

  12. The role of the intrinsic cholinergic system of the striatum: What have we learned from TAN recordings in behaving animals?

    Apicella, Paul

    2017-09-30

    Cholinergic interneurons provide rich local innervation of the striatum and play an important role in controlling behavior, as evidenced by the variety of movement and psychiatric disorders linked to disrupted striatal cholinergic transmission. Much progress has been made in recent years regarding our understanding of how these interneurons contribute to the processing of information in the striatum. In particular, investigation of the activity of presumed striatal cholinergic interneurons, identified as tonically active neurons or TANs in behaving animals, has pointed to their role in the signaling and learning of the motivational relevance of environmental stimuli. Although the bulk of this work has been conducted in monkeys, several studies have also been carried out in behaving rats, but information remains rather disparate across studies and it is still questionable whether rodent TANs correspond to TANs described in monkeys. Consequently, our current understanding of the function of cholinergic transmission in the striatum is challenged by the rapidly growing, but often confusing literature on the relationship between TAN activity and specific behaviors. As regards the precise nature of the information conveyed by the cholinergic TANs, a recent influential view emphasized that these local circuit neurons may play a special role in the processing of contextual information that is important for reinforcement learning and selection of appropriate actions. This review provides a summary of recent progress in TAN physiology from which it is proposed that striatal cholinergic interneurons are crucial elements for flexible switching of behaviors under changing environmental conditions.

    2016-10-01

    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.

    1983-03-01

    This report describes the decontamination and decommissioning of the Test Area North (TAN) liquid waste evaporator (PM-2A). The PM-2A facility included the aboveground evaporator system, two underground holding tanks and feedlines, an electrical distribution subsystem, and one above ground concrete tank. Much surface soil of the PM-2A area was also radioactively contaminated. Stabilization of the liquid and sludge in the holding tanks, a major task, was achieved by pumping most of the liquid into 55-gal drums and mixing it with cement. The drums were buried in the Radioactive Waste Management Complex (RWMC). The remaining liquid and sludge were dried in place by layers of diatomaceous earth. The most contaminated surface soil was removed, and the area backfilled with clean topsoil and graded, reducing the surface radiation field to background. A 6-ft-high chain link fence now surrounds the area. Most of the area was seeded to crested wheatgrass. 46 figures, 9 tables

    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

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

    Erten, E.

    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 document the number and variety of indoor tanning facilities and services in New Zealand, and to analyse changes from 1992 to 2006. Hard copies of the Yellow Pages telephone directory listings of all 18 New Zealand regions for 1992, 1996, 2001 and 2006 were examined. Entries under solaria and sun bed headings were supplemented with entries where sun bed/indoor tanning services were explicitly advertised under hairdressing, beauty therapy/supplies, and health and fitness centre categories. Duplicate listings were eliminated. From 1992 to 2006, inclusive, there was a 241% increase in the number of businesses that advertised some form of indoor tanning service in the NZ Yellow Pages telephone directories. There was a 525% increase in the number of wholesale trade providers, indicative of expansion in the industry, overall. Hire services also increased. The reported findings are likely to represent an underestimate of the total numbers of facilities and providers. Substantial growth in indoor tanning facilities and services in New Zealand has occurred since 1992. The evidence of potential serious health risks from sunbed use, in conjunction with evidence of irresponsibility among some providers, suggests a need for regulatory controls to strengthen existing voluntary guidelines. With legislation recently introduced for the states of Victoria and South Australia, and proposed in Queensland and Western Australia before the end of 2008; it would be timely for New Zealand authorities to collaborate with those drafting that legislation.

    Tantalum nitride thin films were deposited by radio frequency (RF) reactive sputtering at various N 2 /Ar gas flow ratios and working pressures to examine the change of their electrical resistivity. From the X-ray diffraction (XRD) and four-point probe sheet resistance measurements of the TaN x films, it was found that the change of the crystalline structures of the TaN x films as a function of the N 2 partial pressure caused an abrupt change of the electrical resistivity. When the hexagonal structure TaN thin films changed to an f.c.c. structure, the sheet resistance increased from 16 Ω/sq to 1396 Ω/sq. However, we were able to control the electrical resistivity of the TaN thin film in the range from 69 Ω/sq to 875 Ω/sq, with no change in crystalline structure, within a certain range of working pressures. The size of the grains in the scanning electron microscopy (SEM) images seemed to decrease with the increase of working pressure

    Full Text Available The vegetable tannins are the oldest tanning agents used in leather industry. They give their natural character and colour to the leathers which they are applied to, but they have the disadvantage of colour change when they are exposed to light for prolonged times. In this study light fastness properties of leathers tanned with mimosa, quebracho, valonea and chestnut tannins were measured. Lightfastness properties of mimosa and quebracho tannins were found lower. Then these tannins were modified with sulphitation, novalac synthesis and sulphomethylation processes. Lightfastness and determination of volatile matter, determination of matter soluble in dichloromethane, determination of sulphated total ash and sulphated water-insoluble ash, determination of water soluble matter, water soluble inorganic matter and water soluble organic matter, determination of nitrogen content and hide substance, calculation of degree of tannage determination of formaldehyde content analyses were performed to the leathers tanned with modified mimosa and quebracho tannins. From comparison of results, it was understood that sulpmethylation process can be used for production of leathers with higher lightfastness and without major change on chemical properties. When chemical properties of leathers tanned with modified quebracho and mimosa are considered: volatile matter, sulphated total ash and sulphated water- insoluble ash, water soluble matter, water soluble inorganic matter and water soluble organic matter, hide substance and formaldehyde contents were found compatible with standard mimosa and quebracho. However degree of tannage and matter soluble in dichloromethane values were found lower, which means some enhancements in modification or fatliquoring process should be considered.

    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.

    Topological semimetals may have potential applications such as in topological qubits, spintronics and quantum computations. Efficient heat dissipation is a key factor for the reliability and stability of topological semimetal-based nano-electronics devices, which is closely related to high thermal conductivity. In this work, the elastic properties and lattice thermal conductivity of TaN are investigated using first-principles calculations and the linearized phonon Boltzmann equation within the single-mode relaxation time approximation. According to the calculated bulk modulus, shear modulus and C 44 , TaN can be regarded as a potential incompressible and hard material. The room-temperature lattice thermal conductivity is predicted to be 838.62 [Formula: see text] along the a axis and 1080.40 [Formula: see text] along the c axis, showing very strong anisotropy. It is found that the lattice thermal conductivity of TaN is several tens of times higher than other topological semimetals, such as TaAs, MoP and ZrTe, which is due to the very longer phonon lifetimes for TaN than other topological semimetals. The very different atomic masses of Ta and N atoms lead to a very large acoustic-optical band gap, and then prohibit the scattering between acoustic and optical phonon modes, which gives rise to very long phonon lifetimes. Calculated results show that isotope scattering has little effect on lattice thermal conductivity, and that phonons with mean free paths larger than 20 (80) [Formula: see text] along the c direction at 300 K have little contribution to the total lattice thermal conductivity. This work implies that TaN-based nano-electronics devices may be more stable and reliable due to efficient heat dissipation, and motivates further experimental works to study lattice thermal conductivity of TaN.

    Leather tanning is an industrial sector of great tradition in Spain that has progressively evolved until it has reached a high degree of technification in the present. However, in its early days, the leather tanning industry has always been considered a dirty and polluting activity, mainly due to the water spills that ended up in the river channels. The Guadalentin Valley between Lorca and Murcia (SE Spain) is characterised by intensive crop and pig production, and an extensive agroalimentary and leather tannery industry. These anthropogenic sources have released salts and metals such as copper (Cu), zinc (Zn) and chromium (Cr) into Guadalentin river. Up to 2003, wastewater was discharged directly to the dry river, immediately upstream of the urban nucleus of Lorca, without any previous treatment. It contained high concentrations of inorganic salts and heavy metals (Cu, Zn and Cr). Spills, in some events, had a flow of 10 000 m3 d-1, with concentration of Cr over 500 mg L-1. Phytoremediation is a sustainable alternative that allows the environmental rehabilitation of fluvial dry sediments through the transfer of heavy metals from the contaminated soils to the native vegetation present. Atriplex halimus, salsola oppositifolia, suaeda vera and tamarix africana were the most representative autochthonous phytoextractor species that were planted to study the degree of decontamination of dry river sediments before planting and 12 months after planting. The sediments characterization was done by a sampling grid of 40 000 m2 (500 m x 8 m) where samples were taken at 3 depths (0-20 cm, 20-50 cm and 5-100 cm) every 50 m. A vegetation study was carried out by random plots of 10 m x 10 m. The results indicated that after 12 months the vegetation cover increased between 35% and 70%. The degree of contamination of Cu, Zn and Cr of the river dry sediments decreased slightly, being the atriplex halimus the plant specie that presented the highest value of the bioaccumulation factor

    Full Text Available O artigo refaz o percurso de Engelmann, lidando em 1962 com perceptos chamados de afetivos até a proposição mais recente de escalões de percepto. O estudo aprofundado dos perceptos afetivos indicavam estados conscientes internos, porém não localizados. Engelmann denominou-os estados subjetivos. Mas deparou que havia ao mesmo tempo outros perceptos internos, esses localizados. A solução era dois escalões: um superior - estados subjetivos - e outro inferior - perceptos internos. Mais tarde Engelmann encontrou estados objetivos, estados conscientes não localizados e externos, representados principalmente por locuções meteorológicas. Finalmente, reestudando um número enorme de experimentos de percepção humana, verificou que havia cinco escalões de percepto, organizados prioritariamente na seqüência seguinte levando em conta o tamanho das partes: estados total, bipartido, supramodal, modal e fragmentário. Os indivíduos são capazes de estar momentaneamente apenas num desses escalões, nunca mais de um. Não se sabe, por enquanto, se é possível representar por intermédio de escalões outras partes da consciência além dos perceptos.Dealing firstly with the affective percepts in 1962 and ending with percept echelons, the paper reconstructs Engelmann's psychological pathway. A serious study of mostly affect percepts indicated nonlocalized internal conscious states. Engelmann called them subjeticve states. But at the same time he found that there were other internal but localized external percepts. He called them objetive states. They were mainly characterized through reporting the weather. Finally, revising numerous perception studies, total, bipartite, supramodal, modal and fragmentary states are found and organizaed through largeness priority. Engelmann called them percepts echelons. In one moment only one percept echelon is possible, not more than one. So far it is not known if others parts of consciousness are divisible

    This study re-analyzed the emulsion stabilizing properties of a low Total Acid Number (TAN) of a high asphaltene crude oil with respect to the role of naphthenic acids. The emulsion stability depended on the pressure/pH. The high interfacial activity of indigenous acids extracted from the crude oil was determined by means of Ion Exchange Resins and by the high organic acid content in the interfacial material extracted from a sludge emulsion. The physical origin of these phenomenological observations was identified using the Fourier Transform Ion Cyclotron Resonance Mass Spectrometry (FT-ICR-MS) and pendant droplet experiments. The interfacial material was composed of a mixture of asphaltenes and organic acids having a wide range of structures (monoprotic, diprotic, fatty, naphthenic and perhaps aromatic) and molecular weights. The interfacial rheology was a 2D gel with an assumed glass transition temperature of approximately 40 degrees C. It was concluded that a synergistic effect of asphaltenes and organic acids promoted the build up of a very structured interface. This interface is more resistant to droplets coalescence than less structured interfaces. Therefore, the disruption of the interfacial layer requires the drainage of individual molecules as well as a collective yield of the gel.

    A series of studies investigated the toxicities of tannery-derived complex mixtures, i.e. vegetable tannin (VT) from Acacia sp. or phenol-based synthetic tannin (ST), and waste-water from tannin-based vs. chromium-based tanneries. Toxicity was evaluated by multiple bioassays including developmental defects and loss of fertilization rate in sea urchin embryos and sperm (Paracentrotus lividus and Sphaerechinus granularis), and algal growth inhibition (Dunaliella tertiolecta and Selenastrum capricornutum). Both VT and ST water extracts resulted in hormetic effects at concentrations ranging 0.1 to 0.3%, and toxicity at levels > or =1%, both in sea urchin embryo and sperm, and in algal growth bioassays. When comparing tannin-based tannery wastewater (TTW) vs. chromium-based tannery effluent (CTE), a hormesis to toxicity trend was observed for TTW both in terms of developmental and fertilization toxicity in sea urchins, and in algal growth inhibition, with hormetic effects at 0.1 to 0.2% TTW, and toxicity at TTW levels > or =1%. Unlike TTW, CTE showed a monotonic toxicity increase from the lowest tested level (0.1%) and CTE toxicity at higher levels was significantly more severe than TTW-induced toxicity. The results support the view that leather production utilizing tannins might be regarded as a more environmentally friendly procedure than chromium-based tanning process.

    The ability of chrome shavings (CS) and buffing dusts of crust leather (BDCL) to remove oily wastes from demineralized water and natural seawater was investigated. The aim of the study was to discover environmentally friendly alternatives for the disposal of solid tannery wastes. The specific surface area of the CS and the BDCL were examined to determine ash content; chromium oxide; fat; and the pH of soluble matter. Scanning electron microscopy (SEM) was then used to examine the structure and morphology of the samples. Three types of oil were used in the experiment: diesel motor oil; premium motor oil; and used motor oil. Sorbent materials were added to a beaker containing 1000 ml of water and 5.5 g of oil. The amount of residual oil in the water was then extracted with petroleum ether. The amount of oil sorbed on the wastes was calculated by subtracting the amount of residual oil in water from the initial mass of oil added to the beakers. Results suggested that the tanned solid wastes efficiently removed the oil from the water. It was concluded that the waste materials were able to absorb many times their weight in oil. 21 refs., 4 tabs., 2 figs.

    Skin cancer is the most common cancer affecting the U.S. Pinterest.com, a virtual bookmarking social media site, has the potential to disseminate skin cancer-related information among young women, the group with the fastest increase in skin cancer diagnosis. This article presents a quantitative content analysis of pins about skin cancer on Pinterest guided by agenda-setting theory and the health belief model. Overall, sun exposure and tanning beds were most frequently discussed as the causes of skin cancer, and alternative therapies such as herbal medicine were discussed more than traditional biomedical treatment or prevention. Highly repinned pins tend to include more information than regular pins. Different types of skin cancer (melanoma, squamous-cell carcinoma, and basal-cell carcinoma) received the same amount of coverage; however, pins about nonmelanoma skin cancer (such as squamous-cell carcinoma and basal-cell carcinoma) were often information-poor. They were less likely to include information on the causes, prevention, and the biomedical treatment of skin cancer and were less likely to include health belief constructs associated with the promotion of skin cancer prevention and treatment.

    In the manufacture of CFRP(Carbon Fiber Reinforced Polymer Composite) composite structures, various independent components join by bolts and pins. Holes for bolts and pins have an effect on the failure strength of such structures, because those act as notches in structures. The failure characteristic of such structures are different from those of plain plate subject to remote load. In this paper, tensile properties of woven CFRP composite plates with laminates of 0 .deg., 30 .deg. and 45 .deg. were obtained according to ASTM D 3039. By using obtained tensile failure strength and Tan-Cheng failure criterion, tensile failure strength of CFRP laminate with arbitrary fiber angle were evaluated. Also, the degradation of tensile properties by center hole({Phi}10mm) with a remote load was evaluated and the failure strengths were applied to Tan's failure criterion, similarly.

    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.

    Dispersible and spherical silica nanoparticles (nano-SiO2) were prepared with tetraethyl silicate and different surface-modifiers via a simple method. The silica nanoparticles surface-modified with methacryloxy (propyl) trimethoxysilane (denoted as MPS-SiO2), dimethyl diallyl ammoniumchloride (denoted as DMDAAC-SiO2) and poly (methacrylic acid) (denoted as PMAA-SiO2) which are known as hydrophobic, amphiphilic and hydrophilic modifiers, respectively, exhibited excellent dispersibility in various solvents or polymer matrix. The obtained bare silica nanoparticles, MPS-SiO2, DMDAAC-SiO2 and PMAA-SiO2 were characterized by Fourier transform infrared spectra (FTIR), thermogravimetric analysis (TGA), transmission electron microscope (TEM) and scanning electron microscope (SEM). A series of nanocomposites (denoted as SiO2/P, MPS-SiO2/P, DMDAAC-SiO2/P and PMAA-SiO2/P, respectively) were also prepared with the bare or surface-modified silica nanoparticles and methacrylic acid-co-acrylamide-co-acrylonitrile-co-salicylic acid tetrabasic copolymer (denoted as PMAAS) and applied in leather tanning. Compared with those of the leather tanned with the commercial acrylic resin (CHINATAN OM) and pure tetrabasic copolymer tanning agents, the physical and mechanical properties, rheological properties and thermal stabilities of the leather treated with SiO2/P, MPS-SiO2/P, DMDAAC-SiO2/P or PMAA-SiO2/P founded to be improved in a significant way. Moreover, the highest shrinkage temperature of the wet-white sheepskin tanned with PMAA-SiO2/P reached to 76 °C and the thickness increase reached to 105%.

    Full Text Available To investigate the effect of restricted grazing time on behavior of Tan sheep on desert steppe, forty 4-months old male Tan sheep with an original body weight (BW of 15.62±0.33 kg were randomly allocated to 4 grazing groups which corresponded to 4 different restricted grazing time treatments of 2 h/d (G2, 4 h/d (G4, 8 h/d (G8 and 12 h/d (G12 access to pasture. The restricted grazing times had a significant impact on intake time, resting time, ruminating time, bite rate and movement. As the grazing time decreased, the proportion of time spent on intake, bite rate and grazing velocity significantly (p<0.05 increased, but resting and ruminating time clearly (p<0.05 decreased. The grazing months mainly depicted effect on intake time and grazing velocity. In conclusion, by varying their foraging behavior, Tan sheep could improve grazing efficiency to adapt well to the time-limited grazing circumstance.

    Denmark has experienced an increase in melanoma incidence since the 1960s. Exposure to ultraviolet radiation is the main preventable cause of this cancer. We examined current travel to, and sun-related behaviour of Danes at, sunny destinations in relation to their risk for sunburn. A population-based sample of 11,158 respondents aged 15-59 years completed three questionnaires in 2007-2009 that included items on exposure to ultraviolet radiation. Using logistic regression analysis we examined the relations between sunny vacations, sun-related behaviour, demographic factors and risk for sunburn. During 2007-2009, 44.8-45.8% of the respondents travelled to a sunny destination at least once a year; 24% became sunburnt, and 69% tanned intentionally. The odds ratio for sunburn in general for people who went on a sunny vacation as compared with those who did not was 1.6 (1.5-1.7). Sunscreen use (1.9; 1.4-2.6) and intentional tanning (3.4; 2.8-4.1) were positively associated with sunburn on vacation. Taking a vacation in a sunny place is a risk factor for sunburn, especially for young people. The recommendation for sunscreen use should be re-evaluated, as intention to tan is the most important factor in sunburn on vacation and should be targeted more strategically.

    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.

  16. A profitable use of by-products of the poultry slaughter. The tanning of hen’s feet skins

    Full Text Available The aim of this development is to add value to one of the by-products of the poultry slaughtery, the chicken’s feet. The process began with the skinning of the chicken’s feet, which underwent a tanning process to obtain a leather characterised for its similarity with exotic leathers such as the reptile ones. To facilitate its possible production by artisanal means we designed a more environmental-friendly process, eliminating the use of sodium sulfide in the stages corresponding to dehairing and liming, followed by a chromium-free tanning based on a combination of vegetable tannins and synthetic retanning agents. Confirmation of the tanning of the skins was performed by measuring the shrinkage temperature of leathers, obtaining a value of 80 °C, higher than those of the raw hides. Physical properties were evaluated to characterize the product, obtaining tensile strength values of 0,65 kg/mm2 and a tear resistance of 2,10 kg/mm.

  19. Mitigation of naphthenate related production upsets in high TAN (Total Acid Number) crude oil

    This paper describes a strategy for prediction, evaluation and mitigation of calcium naphthenate related production problems. Developing fields with acidic crude in the North Sea, West Africa, Bohai Bay (China) and Brazil is becoming more common in recent years. The high acid crude contains a considerable amount of naphthenic acids, typically having a Total Acid Number (TAN) higher than 0.5 mg KOH/g. Formation of either hard type 'calcium naphthenate precipitates' or soft type 'sodium carboxylate/emulsions' during crude oil production can lead to severe flow assurance and separation problems. In severe cases this may lead to production shutdowns to clean-up the equipment. A number of different naphthenate mitigation approaches have been published but no one particular approach is considered to be the most efficient as it depends significantly on the particular field conditions. Initially, this problem was addressed by deploying large volumes of (usually organic) acid, but more recently high efficiency low dose naphthenate inhibitors have been introduced. For predicting naphthenate scaling potential, methods were developed to determine the concentration of 1230 Dalton naphthenic tetra acid (ARN acids) in either deposit or crude oil and this information can be used to locate and potentially isolate the problem to a certain reservoir. Also, methods were developed to design suitable low dose naphthenate inhibitors. As these inhibitors are field tested, monitoring is required to ensure the product is performing most efficiently. In cases of tight emulsions however, this is less difficult as the oil dehydration and water quality is affected instantly. Methods were developed to allow monitoring of the calcium naphthenate deposition in field trails, thus allow trending and evaluation of the chemicals performance. After detailed analyses and discussions of the developed methods, a North Sea case history is presented reviewing several years of treating

  20. Alternative Epistemologies in Budjette Tan and Kajo Baldisimo’s TRESE

    Ana Micaela Chua

    2016-12-01

    Full Text Available Postmodern readings are premised on the dissolution of grand narratives, disallowing the imagination of unity or truth, and giving primacy to decentering as novelty. Working against such a tendency, this essay presents a reading of Budjette Tan and Kajo Baldisimo’s TRESE as a text grounded in particular social epistemologies, which allows the text to speak of Metro Manila as a unified entity where people share realities and myths. TRESE, I argue here, locates the impulse for resolution in alternative systems of knowledge— often between superstition and grand narrative—that are easily available, but often too quickly dismissed as useless or outmoded. In stories such as “Wanted: Bedspacer” and “Cadena de Amor,” different ways of accessing knowledge are allowed to play vital roles in detection without totally devaluing rational analyses. These alternatives to logic and science may themselves vary: from superstitions to the properly arcane, from “common sense” to emotional and sociological understanding of human interaction. The text engages in myth-making in an effort to approximate cultural unity, where such unity has always been problematic, by imagining alternative access points to truth; this is a move that must be read in the context of a culture that is not irrational or anti-rational, but one in which rationality is only one way of accessing knowledge. TRESE empowers alternative systems of knowledge that allow us to better comprehend ourselves as a society. In this essay I employ critical insights from Kumkum Sangari’s “The Politics of the Possible,” through which TRESE can be read as a text that is not simply a novelty, but as one in which popular tropes and strategies of myth-making come together to present the possibility of a vision of a Philippine urban culture that embraces both the fantastic and the real, rather than being divided between them.

    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. Copyright © 2015 Elsevier Ltd.

    R/V Tangaroa's voyage TAN0607, 20 June to 2 July 2006, Wellington/Wellington, was the first-ever research campaign dedicated to studying gas hydrates on the Hikurangi margin. The cruise was a collaboration between GNS Science, the US Naval Research Laboratory, the National Institute of Water and Atmospheric Research, the Universities of Otago, Hawaii, and Rochester (New York), as well as individual scientists from the University of Auckland and the GeoForschungsZentrum Potsdam. We collected high-resolution seismic data, EM 300 swath bathymetry, 3.5 kHz sub-bottom, as well as 12, 38 and 120 kHz water column echosounder data. Piston cores were recovered for pore water chemistry, microbiology, core description, and paleoceanographic analyses. We acquired heatflow data using a violin-bow type probe rented from the Geological Survey of Canada. We also retrieved three dredge samples from the seafloor. Finally, Niskin bottles attached to CTDs were used to collect seawater for water-column chemistry. The cruise focused on two study areas, the Porangahau Ridge offshore of the Wairarapa and the Rock Garden off Hawke's Bay. Seismic data from 2005 showed an amplitude anomaly beneath the Porangahau Ridge that appears to be caused by gas within the regional gas hydrate stability zone and may indicate the presence of highly concentrated gas hydrates in the vicinity. We acquired nine seismic lines across the ridge to constrain the lateral extent of this anomaly. The anomaly seems to develop with folding and may be linked to enhanced fluid flow through the gas hydrate stability field, which in turn may lead to elevated gas hydrate concentration. Pore water chemistry shows a shoaling of the base of the sulfate reduction zone across this feature, indicative of elevated methane flux through the hydrate stability field. There is a distinct thermal anomaly across the Porangahau Ridge, albeit with a complex signature. On the other hand, there are no indications of methane expulsion into

  3. Geodetic mass balance of the Patagonian Icefields from STRM and TanDEM-X DEMs

    The Northern and Southern Patagonian Icefields (NPI & SPI), represent the largest mid-latitude ice masses in the Southern Hemisphere. They are mostly drained by outlet glaciers with fronts calving into fresh water lakes or Pacific fjords. Both icefields were affected by significant downwasting in the last decades, as confirmed by published mass change trends obtained by means of gravimetric measurements and geodetic methods. Given their unique characteristics and the significant contribution to sea level rise per unit of area, they represent a fundamental barometer for climate research. The Shuttle Radar Topography Mission (SRTM) of 2000 provided the most complete and accurate Digital Elevation Model (DEM) at the time covering the entire globe from 56°S to 60°N. The present TanDEM-X mission shares the same objective aiming at a global coverage with much higher resolution and accuracy. Their combination leads to a unique multitemporal elevation dataset based solely on SAR single pass bistatic interferometry characterized by 11 to 16 year time span: an ideal setup for monitoring long-term large-scale geophysical phenomena. Using this dataset, detailed and extensive ice elevation change maps were obtained for the 12900 km² SPI for the observation period 2000 - 2011/2012 and for the 3900 km² NPI for the period 2000 - 2014. These maps were used to compute the glacier mass balance of the icefields through the geodetic method. Particular emphasis was set on the estimation of the uncertainty of the geodetic mass balance by quantifying all relevant sources of error. Among these, signal penetration into dry ice and snow can affect considerably radar elevation measurements. For this purpose the backscattering coefficient of the acquisitions along with concurrent meteorological data were analyzed to assess the conditions of the icefield surface. Mass change rates of -3.96±0.14 Gt a-1 and of -13.14±0.42 Gt a-1 (excluding subaqueous loss) were obtained for NPI and SPI

  4. Phenotypic Plasticity through Transcriptional Regulation of the Evolutionary Hotspot Gene tan in Drosophila melanogaster.

    Full Text Available 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. Sensitivity of t

    Full Text Available El presente artículo problematiza el rol del comunicador como intelectual en relación a los procesos de apropiaciones barriales locales de la ciudad de Salta, como problemática sociocultural actual. Esto en vinculación a las posibilidades de producción de conocimiento científico ‘con los otros’ y ‘desde los márgenes’. Se parte de considerar que las sociedades del mundo actual se caracterizan por su velocidad, por lo emergente. Estas son sociedades complejas donde nada permanece y donde nada es seguro, donde las certezas se rompen. En tal realidad, donde la transformación es moneda corriente, es imprescindible problematizar el rol que han tenido, tienen y deberían tener los comunicadores como intelectuales. Teniendo en cuenta que las sociedades se modifican constantemente, en las últimas décadas tanto en el país en general, como en la provincia de Salta en particular, se han dado una serie de cambios estructurales, lo que ha desembocado en procesos de transformaciones urbanas. Ante esta realidad de crecimiento urbano, es necesario pensar en las nuevas formas de acceso a la vivienda y al papel que el estado ocupa en tal situación, para dar cuenta de cómo es que un sector de la sociedad que se considera al margen, tiene real y concreta existencia y que lucha por el reconocimiento de sus derechos básicos como ciudadanos. La vida al margen no es algo novedoso, ya que siempre ha habido personajes que han sido obligados a vivir en los márgenes, fuera de lo central, en las periferias, aludiendo a algo que se deja de lado, que se excluye. Es en este contexto, donde se problematiza la posibilidad de producción de conocimiento, ya no desde los lugares considerados tradicionales, como la academia, sino más bien desde una perspectiva alternativa, compartida con los actores sociales.

    In the present paper, eggshell and powdered marble, two carbonaceous materials, were used to remove Cr(III) ions from a real chrome tanning wastewater. The effects of initial effluent pH, adsorbent dose, contact time and temperature were studied. The maximum uptake of chromium ions was obtained at pH 5.0 with the dose 20 g L(-1) and 12 g L(-1) for eggshell and powdered marble respectively. Adsorption equilibrium was reached after 14 h contact time for eggshell and only after 30 min for powdered marble. Under these conditions, almost 99% Cr(III) was removed from chrome tanning wastewater having an initial concentration of chromium of 3.21 g L(-1). Kinetic data were satisfactorily described by a pseudo-second order chemical sorption model. The equilibrium rate constant was notably greater for powdered marble than for eggshell with 1.142·10(-3) (g mg(-1) min(-1)) and 0.041·10(-3) (g mg(-1) min(-1)) respectively. The adsorption isotherm were well described by a Langmuir model and showed that the interaction of chromium with the two adsorbents surface is a localized monolayer adsorption with a smaller energy constant for the powdered marble than for eggshell (0.020 (L mg(-1)) and 0.083 (L mg(-1)) respectively). The powdered marble was able to adsorb faster a large amount of Cr (III) in comparison to eggshell. The use of a standardized lettuce seed bioassay allowed evaluating a better effectiveness of the Cr adsorption on the powdered marble, removing up to 40% of the treated effluent toxicity than by eggshell 25%. The powdered marble could be considered as an effective, low cost carbonaceous material to be used for chromium removal from tanning wastewater. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Using the terror management health model (J. L. Goldenberg & J. Arndt, 2008), the authors examined tanning outcomes as a function of priming tanning-relevant standards for attractiveness after reminders of death. Study 1 consisted of 101 female college students recruited from a midwestern university; Study 2 consisted of 53 female participants recruited from a beach in south Florida. In both experiments, participants answered questions about their mortality or a control topic, and were presented with a fashion article that highlighted either the attractiveness of tanned (just in Study 1), pale, or natural-looking skin. Self-reported suntan intentions (Study 1) and sunscreen intentions (Study 2). Study 2 also assessed participants' interest in various sun protection products. Study 1 demonstrated that mortality salience led to higher tanning intentions when the association between tanned skin and physical attractiveness was made salient and reduced intentions when the attractiveness of paler skin was highlighted. In Study 2, beachgoers, after reminders of death, reported greater preference for high sun protection sunscreen after reading an article about the attractiveness of paler skin tones. These findings contribute to an emerging understanding of how mortality concerns can influence health-related judgment and behavior. PsycINFO Database Record (c) 2009 APA, all rights reserved.

    Thin films were synthesized in a magnetron sputtering system using a target of Ta with 99.99% purity and silicon substrates (1 1 1). The gases used for the film growth were (Ar + N{sub 2}), (Ar + CH{sub 4} + N{sub 2}) and (Ar + CH{sub 4}) mixtures for TaN, TaCN and TaC, respectively. The substrate temperature increased from room temperature to 500 °C. The chemical composition and bonding configuration were examined using X-ray photoelectron spectroscopy (XPS), revealing Ta-N, Ta-C-N, Ta-C and C-C bonds. Moreover, the crystallographic structure was analyzed using X-ray diffraction (XRD), indicating the presence of (1 1 1) and (2 0 0) planes belonging to a face-centered cubic structure. The stoichiometry variation dependence on the CH{sub 4} and N{sub 2} flow was analyzed, and the influence of the substrate temperature on the coatings was investigated. Finally, scanning electron microscopy (SEM) was used to determine the evolution on the grain formation in the coatings as the substrate temperature increased.

    This case study analysed the impact of the global economy on the environment of the Vale do Rio do Sinos region in southern Brazil. Interviews and questionnaires were used to collect data from social, cultural, economic and political agents in this region, and documents about the tanning industry were reviewed and analysed. Global perspectives and local conditions were brought together to understand the causes and consequences of social, political and economic structures and to evaluate the intrinsic association of the tanning industry with the social, historical and cultural development of the Vale do Rio dos Sinos. The behaviour of the local community, where individuals believe that progress is primordially based on industrial development and go to any lengths to achieve it, was also studied. The analysis of industries that have a high contamination potential revealed that dirty industries moved from central to peripheral countries up to the 1980s, but movement is currently internal and occurs between states in Brazil due to several types of incentives.

    Concern regarding the impact of indoor tanning devices on human health has led to different regulations and recommendations, which set limits on erythema-weighted irradiance. Here, we analyze spectral emissions from 52 tanning devices in Spanish facilities and compare them with surface solar irradiance for different solar zenith angles. Whereas most of the devices emitted less UV-B radiation than the midday summer sun, the unweighted UV-A irradiance was 2-6 times higher than solar radiation. Moreover, the spectral distributions of indoor devices were completely different from that of solar radiation, differing in one order of magnitude at some UV-A wavelengths, depending on the lamp characteristics. In 21% of the devices tested, the erythema-weighted irradiance exceeded 0.3Wm(-2): the limit fixed by the European standard and the Spanish regulation. Moreover, 29% of the devices fall within the UV type 4 classification, for which medical advice is required. The high variability in erythema-weighted irradiance results in a wide range of exposure times to reach 1 standard erythemal dose (SED: 100Jm(-2)), with 62% of devices requiring exposures of solar UV-A dose.

    Full Text Available This case study analysed the impact of the global economy on the environment of the Vale do Rio do Sinos region in southern Brazil. Interviews and questionnaires were used to collect data from social, cultural, economic and political agents in this region, and documents about the tanning industry were reviewed and analysed. Global perspectives and local conditions were brought together to understand the causes and consequences of social, political and economic structures and to evaluate the intrinsic association of the tanning industry with the social, historical and cultural development of the Vale do Rio dos Sinos. The behaviour of the local community, where individuals believe that progress is primordially based on industrial development and go to any lengths to achieve it, was also studied. The analysis of industries that have a high contamination potential revealed that dirty industries moved from central to peripheral countries up to the 1980s, but movement is currently internal and occurs between states in Brazil due to several types of incentives.

    Full Text Available This investigation was aimed at introducing natural dye extracted from the bark of Cassia Singueana plant for dyeing chrome tanned sheep skin crust leather. The colorant was extracted by aqueous extraction and its strength evaluated using UV-Visible spectroscopy. The extraction with the highest strength (3.9 at λmax of 400 nm was obtained at temperature of 95°C, concentration of 60 g/l, and time of 60 minutes. The possibility of using aloe vera juice and mango bark extract as natural mordants for leather coloration was investigated. Dyeing was conducted with and without mordant using different combinations of temperature, time, pH, and concentration of mordants. All three mordanting techniques were evaluated. The color strength (K/S, CIE L⁎a⁎b⁎ values, and fastness properties (light, rubbing, and perspiration of dyed leather samples were evaluated using appropriate instruments and according to international standards. Majority of samples exhibited that fastness result was in the range of good-excellent. Significantly better color fastness was obtained in case of leather samples premordanted with aloe vera. This study leads to the conclusion that dye extracted from bark of Cassia singueana can be used as colorant for tanned leather with the selected natural mordants.

    Full Text Available Chromium used in leather manufacturing can be oxidized from the trivalent to the hexavalent state, causing environmental concerns. In this study, the influence of Cr(III from tanning, deacidification pH, fatliquors, chrome retanning and vegetable retanning on the formation of Cr(VI in leather was analyzed by comparing natural and aged samples. In wet-blue leather, even after aging and in fatliquored leathers that did not suffer the aging process, the presence of Cr(VI was always below the detection limit of 3 mg/kg. Considering the presence of Cr(VI, the supply of chromium during the retanning step had a more significant effect than during the tanning. In the fatliquoring process with sulfites, fish and synthetic fatliquor leather samples contained Cr(VI when aged, and the highest concentration detected was 26.7 mg/kg. The evaluation of Cr(VI formation led to recommendations for regulation in the leather industry.

    Highly toxic contaminants like Cr, As, and Pb were detected in chrome-tanning process of animal skin to produce leather by applying locally developed laser-induced breakdown spectrometer. An Nd-YAG laser with 1,064 nm wavelength was focused on the surface of leather samples (natural and manufactured) to generate a plasma spark and spectrally resolved spectra were used for identification and quantification of contaminants. The leather samples were collected from a tannery located in industrial cities of Riyadh and Jeddah, Saudi Arabia. The study was carried out on fully, half manufactured (wet blue leather), and natural hide (skin). To the best of our knowledge, this is the first attempt where laser-induced breakdown spectroscopy (LIBS) technique has been applied for the analysis of leather before and after tanning process. The maximum concentration of different elements of environmental significance like chromium, lead, arsenic, sulfur, magnesium were 199, 289, 31, 38, and 39 ppm, respectively, in one of the manufactured leather samples. The limit of detection (LOD) of our LIBS system for chromium, lead, arsenic, sulfur, and magnesium were 2, 3, 1.5,7, and 3 ppm, respectively. The safe permissible limit for tanned leather for highly toxic elements like chromium, lead, and arsenic are 1, 0.5, 0.01 ppm, respectively, as prescribed in Environmental Regulation Standards for Saudi Industries set by Royal Commission Jubail, Saudi Arabia. The LIBS technique is superior to other conventional techniques like ICP or atomic absorption that a little or no sample preparation is required, no chemicals are needed, multi-elemental analysis is possible for all kinds of samples (natural and anthropogenic materials), microgram of sample is essential, and LIBS could be applied for remote analysis. It is highly selective and sensitivity higher than ICP, and as no sample and chemicals are required, it is cost effective for multi-sample analysis per unit time as compared with other

    Several large-scale maps of forest AGB have been released [1] [2] [3]. However, these existing global or regional datasets were only approximations based on combining land cover type and representative values instead of measurements of actual forest aboveground biomass or forest heights [4]. Rodríguez-Veiga et al[5] reported obvious discrepancies of existing forest biomass stock maps with in-situ observations in Mexico. One of the biggest challenges to the credibility of these maps comes from the scale gaps between the size of field sampling plots used to develop(or validate) estimation models and the pixel size of these maps and the availability of field sampling plots with sufficient size for the verification of these products [6]. It is time-consuming and labor-intensive to collect sufficient number of field sampling data over the plot size of the same as resolutions of regional maps. The smaller field sampling plots cannot fully represent the spatial heterogeneity of forest stands as shown in Figure 1. Forest AGB is directly determined by forest heights, diameter at breast height (DBH) of each tree, forest density and tree species. What measured in the field sampling are the geometrical characteristics of forest stands including the DBH, tree heights and forest densities. The LiDAR data is considered as the best dataset for the estimation of forest AGB. The main reason is that LiDAR can directly capture geometrical features of forest stands by its range detection capabilities.The remotely sensed dataset, which is capable of direct measurements of forest spatial structures, may serve as a ladder to bridge the scale gaps between the pixel size of regional maps of forest AGB and field sampling plots. Several researches report that TanDEM-X data can be used to characterize the forest spatial structures [7, 8]. In this study, the forest AGB map of northeast China were produced using ALOS/PALSAR data taking TanDEM-X data as a bridges. The TanDEM-X InSAR data used in

    Leather industry generates huge amount of chrome-containing leather solid waste which creates major environment problems to tanners worldwide. Chrome-tanned leather solid waste is primarily chromium complex of collagen protein. The presence of chromium limits its protein application in animal feed industry. The purified protein hydrolysate with zero chromium could be used in poultry feed. In this study, an attempt has been made to assess performance of poultry with purified protein hydrolysate as a feed derived from chrome-tanned leather waste as partial replacement of soyabean meal as a sole source of protein for growing broiler chickens. Growth study was conducted to evaluate the effect of feeding protein hydrolysate on performance and physiochemical characteristics of meat of broiler chickens. Two experimental diets containing various levels of protein hydrolysate (EI-20 % and EII-30 %) were evaluated. The comparative study was performed as control with soyabean meal. Daily feed intake, body weight gain and feed conversion ratio were measured from day 8 to day 35. At the end of the study, birds were randomly selected and slaughtered to evaluate for physiochemical characteristics of meat. Diet had significant effects on feed intake and body weight gain. Birds fed with 20 and 30 % protein hydrolysate consumed 9.5 and 17.5 % higher amount of feed and gained 6.5 and 16.6 % higher than soyabean meal-fed birds. The current study produced evidence that protein hydrolysate can replace up to 75 % of soyabean meal in broiler diets without affecting either growth performance or meat characteristics.

    Using the same time data of PM2.5 concentration and meteorology from May 1st to May 31st in 2013 in Chang-Zhu-Tan area. This paper analyses the variation characteristics of PM2.5 concentration and the correlations between the variation characteristics and meteorological factors. In view of time, the results showed that the 24-h PM2.5 concentration varied with the two peaks and two valleys styles in Chang-Zhu-Tan area. And the daily PM2.5 concentration tends to the instability and great variation characteristics with the multi-peaks and multi-valleys style. In view of space, PM2.5 concentration values of the three cities from high to low are Zhuzhou>Xiangtan>Changsha. For cities and suburbs, PM2.5 concentration values of central towns are greater than that of the suburbs in Changsha and Xiangtan; however, the PM2.5 concentration values of the central town in Zhuzhou are slightly lower than the suburbs. At the same time, the correlation analysis between PM2.5 concentration and meteorological factors showed that the correlation from high to low was the relative air humidity>soil temperature>air temperature>soil humidity> wind velocity>rainfall. Among the above meteorological factors, wind velocity, rainfall, air temperature, soil temperature and soil humidity are negatively correlated with PM2.5 concentration, but the relationship between relative air humidity and PM2.5 concentration is a positive correlation.

    Full Text Available The use of Interferometric Synthetic Aperture Radar (InSAR data has great potential for monitoring large scale forest above ground biomass (AGB in the tropics due to the increased ability to retrieve 3D information even under cloud cover. To date; results in tropical forests have been inconsistent and further knowledge on the accuracy of models linking AGB and InSAR height data is crucial for the development of large scale forest monitoring programs. This study provides an example of the use of TanDEM-X WorldDEM data to model AGB in Tanzanian woodlands. The primary objective was to assess the accuracy of a model linking AGB with InSAR height from WorldDEM after the subtraction of ground heights. The secondary objective was to assess the possibility of obtaining InSAR height for field plots when the terrain heights were derived from global navigation satellite systems (GNSS; i.e., as an alternative to using airborne laser scanning (ALS. The results revealed that the AGB model using InSAR height had a predictive accuracy of R M S E = 24.1 t·ha−1; or 38.8% of the mean AGB when terrain heights were derived from ALS. The results were similar when using terrain heights from GNSS. The accuracy of the predicted AGB was improved when compared to a previous study using TanDEM-X for a sub-area of the area of interest and was of similar magnitude to what was achieved in the same sub-area using ALS data. Overall; this study sheds new light on the opportunities that arise from the use of InSAR data for large scale AGB modelling in tropical woodlands.

The research conducted on the territory of the Baikal-Kudara forest area of the Republic of Buryatia (52°10'N, 106°48'E. Forest vegetation is represented mainly by conifers – pine, and spruce, with a small admixture of deciduous trees – aspen, birch, etc. The forest vegetation height was determined by subtracting the digital elevation model (DEM of the digital terrain model (DTM. DEM is built according to the L-band (wavelength of 23.5 cm ALOS PALSAR satellite with horizontal co-polarization mode. In the investigation it was assumed that a radar signal of ALOS PALSAR passes all forest thickness and reflected from the underlying surface, made it possible to recover terrain under forest canopy. DTM has been built using the TanDEM-X data (wavelength 3 cm. In this case, it was assumed that the radar echoes scattered from a some virtual phase centers of scattering surface, which characterizes the upper limit of the continuous forest canopy. To check the accuracy of satellite definitions of forest height in study area were made high-precision geodetic measurement of trees heights using electronic total station and the coordinates of geographic control points using differential GPS receivers. The discrepancy between the satellite and ground-based measurements at 11 test sites did not exceed 2 m, which is mainly due to the difference in measurement techniques: height of individual trees by ground methods and continuous forest canopy height using radar interferometry.

    Skin cancer is an increasingly important global public health problem. Mass media is a key source of skin cancer information. We examined how media coverage of skin cancer has changed over time as a consequence of the release of a key public health report from the International Agency for Research on Cancer (IARC) in 2006, which linked ultraviolet (UV) radiation from indoor tanning and skin cancer. A directed content analysis of skin cancer and tanning coverage in 29 popular North American magazines (2001-2012) examined reporting of skin cancer risk factors, UV behaviors, and early detection in article text (n = 761) and images (n = 1267). Chi-square and correlational analyses were used determine whether coverage changed in relation to the 2006 IARC report. The total volume of articles about skin cancer and tanning increased modestly after the IARC report (χ (2) = 4.57, df = 1, p Magazines were more likely to encourage sunscreen use (χ (2) = 11.55, df = 1, p magazines to promote sun avoidance (χ (2) = 6.82, df = 1, p magazine reporting, there is a need for more effective dissemination of public health messages about skin cancer and tanning.

    As an important commercial trait for sheep, curly fleece has a great economic impact on production costs and efficiency in sheep industry. To identify genes that are important for curly fleece formation in mammals, a suppression subtractive hybridization analysis was performed on the shoulder skin tissues exposed to two different growth stages of Chinese Tan sheep with different phenotypes (curly fleece and noncurling fleece). BLAST analysis identified 67 differentially expressed genes, of which 31 were expressed lower and 36 were expressed higher in lambs than in adult sheep. Differential expressions of seven randomly selected genes were verified using quantitative real-time polymerase chain reaction (qRT-PCR). KRT71 gene was selected for further study due to its high correlation with the curly hair phenotype in various mammal species. Semi-qPCR showed distinctively high expression of KRT71 in skin tissues. Moreover, qPCR result showed a significantly higher expression of KRT71 in curly fleece than noncurling Tan sheep. The luciferase assay and electrophoresis mobility shift assay showed that there were transcription factor binding sites in the promoter region of KRT71 related to the differential expression of KRT71 at the two growth stages of Tan sheep. Online bioinformation tools predicted MFZ1 as a transcriptional factor that regulates the expression of KRT71. These studies on KRT71 gene revealed some mechanisms underlying the relationship between the KRT71 gene and the curly fleece phenotype of Tan sheep.

    Recent studies have demonstrated that a tanning lamp emitting predominantly ultraviolet (UV) A induces significant yields of the type of potentially mutagenic DNA damage that are associated with the onset of skin cancer (i.e. cyclobutane pyrimidine dimers). UV-induced immunosuppression is also an important event leading to skin cancer. To the modulation of key immunological molecules following exposure to a broad-spectrum UVB lamp and a predominantly UVA-emitting tanning lamp using model in vitro systems. We compared secretion and mRNA expression of interleukin (IL)-6 and tumour necrosis factor (TNF)-alpha in normal human epidermal keratinocytes, and interferon (IFN)-gamma-induced intracellular adhesion molecule (ICAM)-1 in normal human fibroblasts irradiated in vitro with a broad-spectrum UVB lamp or with a Philips 'Performance' tanning lamp. With broad-spectrum UVB irradiation, upregulation of IL-6 and TNF-alpha mRNA was detected 6 h after irradiation, and a dose-dependent increase of cytokines in the supernatants of irradiated cells was found 24 h after irradiation. In contrast, there was no cytokine secretion and little evidence for mRNA upregulation following exposure to a tanning lamp. When cells were exposed first to broad-spectrum UVB, then the tanning lamp, UVB-induced cytokine secretion was inhibited, although mRNA levels were upregulated to a level close to that observed with UVB alone. By using a Schott WG 320 nm filter to attenuate the level of UVB relative to UVA emitted by the tanning lamp, the inhibition of cytokine secretion was shown to be associated with UVA exposure. Both UV sources inhibited IFN-gamma-induced ICAM-1 mRNA expression in a dose-dependent fashion. By using a Schott WG 335 nm filter, inhibition of ICAM-1 mRNA expression by the tanning lamp was shown to be associated with UVB exposure. These results suggest that UV sources emitting different levels of UVA and UVB have differential effects on the modulation of different

    Full Text Available O pressuposto deste ensaio é o de que, ao longo de sua trajetória, a educação ambiental foi constituindo uma narrativa que lhe é própria. Algumas palavras com sentidos conceituais polissêmicos, como natureza, participação, solidariedade, cooperação, autonomia, interdisciplinaridade e, mais recentemente, sustentabilidade, transdisciplinaridade e transversalidade, fundamentam a Educação Ambiental e fazem parte de seu léxico ou de sua rede semântica. O objetivo é analisar os campos do sentido produzidos por alguns desses termos e a trama de inter-relações entre os sujeitos e suas práticas discursivas, recusando a doutrina da unidade da razão e de um sujeito unitário em direção ao objetivo da perfeita coerência. Como a linguagem forma-se no seio de uma cultura, transita entre o individual/ coletivo, o subjetivo/ cultural, no caso da Educação Ambiental, é carregada de sentidos e de significados de um paradigma emergente, de novos modos de sensibilidades entre utopistas e utopias. É propósito entender se, de fato, a Educação Ambiental, em nome da emancipação, opõe-se ao projeto liberal de uma "razão educadora", de um conhecimento-regulação, de uma educação universal baseada em métodos universais, analisando de modo complexo a função social das narrativas generalistas e/ou denunciatórias. Foi considerado tanto o potencial positivo como os limites analíticos e estratégicos das narrativas que se manifestam de forma auto-referenciais. A preocupação central e conclusiva é: as práticas cotidianas que demandam iniciativas e encaminhamentos podem fazer sentido e criar campos de interface para o exercício de uma Educação Ambiental?The assumption behind this essay is that, throughout its history, environmental education constituted a narrative of its own. Some conceptually polysemic words such as nature, participation, solidarity, cooperation, autonomy, interdisciplinarity, and, more recently, sustainability

    Full Text Available OBJECTIVE: This report aims to 1 explain and illustrate the use of the subjective well-being (SWB approach as an alternative health-valuation methodology by estimating the monetary value of five general categories of illness in Costa Rica, and 2 foster comparative research on the advantages and limitations of alternative approaches to health valuation. METHOD: Use of the SWB valuation approach to measure the monetary value of illness (MVI, based on empirical data from a representative survey in Costa Rica carried out in 2004. The MVI is defined as the estimated percentage of monthly income that would be required to compensate for the loss in life satisfaction (LS-a primary SWB conception-that is expected to occur with the onset of illness. The five general categories of illnesses studied were cancer, cardiovascular disease, thyroid disease, arthritis, and infectious disease. RESULTS: There was wide disparity in the monetary values of the different illnesses. Some illnesses had relatively high monetary value compared to persons' mean income, indicating the high value of good health and of programs that aim to prevent the emergence of illnesses or abate their negative impact on people's well-being. CONCLUSIONS: The SWB valuation approach can be used to estimate illnesses' monetary value and thus can contribute to the design of health policies related to resource allocation and compensation, and revenue-generating schemes.OBJETIVOS: Explicar e ilustrar el uso del enfoque del bienestar subjetivo (BS como metodología alternativa para evaluar la salud mediante la estimación del valor monetario de cinco categorías de enfermedades en Costa Rica y promover investigaciones comparativas sobre las ventajas y las limitaciones de enfoques alternativos para la valoración de la salud.

    Full Text Available This paper presents the results of a qualitative research that explores, from an intergenerational and gender perspective, how the use of audiovisual media influences to personal well-being in adolescence. Three, semi-structured group interviews were used with adolescent girls (aged 12 to 18 years, and two with mothers of boys and girls of those ages. The results show that interpersonal relationships are one of the factors that greatly contribute to the adolescents’ well-being. Girls said that the use of technology generates personal well-being because it allows them to maintain interpersonal relationships with their peers. The mothers, however, question whether overuse of technology can contribute to their personal well-being. On the other hand, girls and mothers agree to comment that the use of technology hinders the relationships that adolescents have with their parents.

     

    El presente artículo expone los resultados de una investigación cualitativa que explora, desde la perspectiva intergeneracional y de género, de qué forma el uso de los medios audiovisuales influye en el bienestar subjetivo en la adolescencia. Se han realizado tres entrevistas grupales semi-estructuradas con chicas adolescentes (de 12 a 18 años y dos con madres de chicos y chicas de estas edades. Los resultados avalan una vez más que las relaciones interpersonales son uno de los factores que en mayor medida influye en el bienestar de los y las adolescentes. Las chicas manifiestan que el uso de las tecnologías audiovisuales contribuye a su bienestar subjetivo porque les posibilita mantener las relaciones interpersonales con sus iguales. Las madres, en cambio, ponen en duda que un uso excesivo de las tecnologías pueda contribuir al bienestar subjetivo. Por otra parte, chicas y madres coinciden en comentar que el uso de las tecnologías dificulta las relaciones de los adolescentes con sus progenitores.

    Street dusts collected from 20 locations in the Chang-Zhu-Tan (Changsha, Zhuzhou, and Xiangtan) region, Hunan, China, in May to July 2006, were investigated for sources of polycylic aromatic hydrocarbons (PAHs). The individual PAH concentrations were in the range of 10-4316 ng g(-1), and ∑PAHs(16) levels were in the range of 3,515-24,488 ng g(-1), with a mean of 8,760 ng g(-1). The high-molecular-weight PAHs (four to six rings), ranging from 47.51 to 82.11 %, with a mean of 74.79 %, were the dominant PAH compounds in almost all of the dusts. The isomer ratios suggested a rather uniform mixture of coal combustion and petroleum PAH sources. Factor analysis and multiple linear regression analysis indicate that the main sources of the 16 PAHs were coal combustion/vehicle exhaust, coking/petroleum, and plant combustion, with contribution rates of 50.9, 35.01, and 14.08, respectively. The spatial distributions of PAH concentrations were significantly related to the distribution of industries, traffic circulation, and farmland in this region.

    The essential oils from peels and leaves of Citrus clementine Hort. ex Tan. were extracted via two methods: conventional hydrodistillation (CHD) and microwave-assisted hydrodistillation (MAHD). Their physicochemical properties were investigated. Their chemical compositions of the oils were...... determined by GC/FID and GC/MS. A total of forty-one and seventy-seven compounds of the total essential oil composition of the peels and leaves respectively were identified. The peel oils were dominated by monoterpene hydrocarbons in which limonene was the main component (95.48% [CHD], and 95.03% [MAHD......]). The leaf oils were also dominated by sesquiterpene hydrocarbons with sabinene (26.02% [CHD], and 19.52% [MAHD]), β-elemene (10.50% [CHD], and 18.04% [MAHD]), linalool (9.88% [CHD], and 7.51% [MAHD]), (E)-β-ocimene (5.87% [CHD], and 5.00% [MAHD]), β-caryophyllene (4.04% [CHD], and 7.49% [MAHD]), and δ...

    Full Text Available Este ensayo presenta una nueva manera de entender el funcionamiento de los mercados financieros. Su diferencia clave con la teoría convencional es que reconoce que los inversionistas no invierten directamente en valores sino a través de agentes tales como los administradores de fondos. Los agentes tienen objetivos diferentes y mejor información que sus clientes, y esta asimetría es fuente de ineficiencia: mala fijación de precios, burbujas y colapsos de Bolsa. Un resultado independiente es que los agentes pueden capturar la masa de ganancias de las innovaciones financieras. Los problemas de principal-agente ayudan a explicar por qué el sector financiero global se ha vuelto tan hipertrofiado, rentable y propenso a crisis. La acción remedial consiste en que los principales modifiquen la manera de contratar o instruir a los agentes. El ensayo termina con un manifiesto de políticas que los fondos de pensiones y otros grandes inversionistas pueden adoptar para atenuar los efectos destructivos de la delegación sobre sus beneficios individuales, y promover el bienestar social en forma de un sector financiero más esbelto, eficiente y estable.

    This study explored the feasibility of using TanDEM-X (TDX) interferometric observations of tidal flats for digital elevation model (DEM) construction. Our goal was to generate high-precision DEMs in tidal flat areas, because accurate intertidal zone data are essential for monitoring coastal environment sand erosion processes. To monitor dynamic coastal changes caused by waves, currents, and tides, very accurate DEMs with high spatial resolution are required. The bi- and monostatic modes of the TDX interferometer employed during the TDX science phase provided a great opportunity for highly accurate intertidal DEM construction using radar interferometry with no time lag (bistatic mode) or an approximately 10-s temporal baseline (monostatic mode) between the master and slave synthetic aperture radar image acquisitions. In this study, DEM construction in tidal flat areas was first optimized based on the TDX system parameters used in various TDX modes. We successfully generated intertidal zone DEMs with 57-m spatial resolutions and interferometric height accuracies better than 0.15 m for three representative tidal flats on the west coast of the Korean Peninsula. Finally, we validated these TDX DEMs against real-time kinematic-GPS measurements acquired in two tidal flat areas; the correlation coefficient was 0.97 with a root mean square error of 0.20 m.

    Raw hide/skins come to the tanners as a by-product of meat industry which is converted into value-added leather as product for fashion market. Leather manufacturing is a chemical process of natural biological matrix. It employs a huge quantity of water and inorganic and organic chemicals for processing and thereby discharges solid and liquid wastes into the environment. One of the potential solid wastes generated from leather industry is chrome-tanned leather shavings (CTLSs), and its disposal is increasingly becoming a huge challenge on disposal to tanners due to presence of heavy metal chromium. Hence, finding a sustainable solution to the CTLS disposal problem is a prime challenge for global tanners and researchers. This paper aims to the deeper review of various disposal methods on CTLS such as protein, chromium, and energy recovery processes and its utilization methodologies. Sustainable technologies have been developed to overcome CTLS solid wastes emanating from leather processing operations. Further, this review paper brings a broader classification of developed methodologies for treatment of CTLSs.

    Many extensions of the Standard Model involve two Higgs doublet fields to break the electroweak symmetry, leading to the existence of three neutral and two charged Higgs particles. In particular, this is the case of the Minimal Supersymmetric extension of the Standard Model, the MSSM. A very important parameter is $\\tan\\beta$ defined as the ratio of the vacuum expectation value of the two Higgs doublets. In this paper we focus on the left-right asymmetry in the production of polarised top quarks in association with charged Higgs bosons at the LHC. This quantity allows for a theoretically clean determination of $\\tan\\beta$. In the MSSM, the asymmetry remains sensitive to the strong and electroweak radiative corrections and, thus, to the superparticle spectrum. Some possible implications of these results are discussed.

Se señala cómo en la psicología social: 1 ha predominado una concepción del cambio social naturalizada por el sentido común, según la cual la sociedad es esencialmente dinámica y los cambios sociales se “sienten” simultáneamente en todos los ámbitos sociales; 2 se señala el aspecto perturbador del cambio; 3 Se muestra su carácter fundamentalmente individual. El análisis crítico de esta situación se organiza en torno a las siguientes preguntas problematizadoras: ¿Por qué a pesar de las “revoluciones” algunas cosas no cambian? ¿Por qué se cristalizan los logros “revolucionarios”? ¿Cómo es que a pesar del autoritarismo y la represión se producen cambios? Dicho análisis se enfoca desde las nociones de habitus y de reducton social, considerando aspectos tales como el tempo psicológico, el tempo institucional, el tempo histórico para hacer una construcción de los procesos que pueden llevar a las transformaciones insensibles, los cambios dolorosos, las permanencias insufribles y los mantenimientos confortables

  18. Caterpillar color patterns are determined by a two-phase melanin gene prepatterning process: new evidence from tan and laccase2.

    The larval color patterns in Lepidoptera exhibit splendid diversity, and identifying the genes responsible for pigment distribution is essential to understanding color-pattern evolution. The swallowtail butterfly, Papilio xuthus, is a good candidate for analyzing marking-associated genes because its body markings change dramatically at the final molt. Moreover, the silkworm Bombyx mori is most suitable for identification of lab-generated color mutants because genome information and many color mutants are available. Here, we analyzed the expression pattern of 10 melanin-related genes in P. xuthus, and analyzed whether these genes were responsible for Bombyx larval color mutants. We found that seven genes correlated strongly with the stage-specific larval cuticular markings of P. xuthus, suggesting that, compared with Drosophila, more genes showed marking specificity in lepidopteran larvae. We newly found that the expression of both tan and laccase2 is strongly correlated with the larval black markings in both P. xuthus and B. mori. The results of F2 linkage analysis and mutant analysis strongly suggest that tan is the responsible gene for Bombyx larval color mutant rouge, and that tan is important in emphasizing black markings of lepidopteran larvae. Detailed comparison of temporal and spatial expression patterns showed that larval cuticular markings were regulated at two different phases. Marking-specific expression of oxidizing enzymes preceded the marking-specific expression of melanin synthesis enzymes at mRNA level, which is the reverse of the melanin synthesis step.

    In the last years has been developed in the cosmetology market the application of ultraviolet radiation (UV) in known equipment s as cameras or tan beds to obtain a change in the pigmentation of the skin. In Mexico, this fashion has entered without the appropriate recommendations of prevention against the risks of the adverse effects from the disproportionate exhibition to such non ionizing energy form; which is electromagnetic radiation in the interval of 400 nm to 100 nm of wave longitude, classified in near UV-A of 400 nm to 315 nm, and distant: UV-B of 315 nm to 280 nm and UV-C of 280 nm to 100 nm. Therefore, they have not been included in the national normative the necessary regulations regarding the operation parameters of the tan cameras for the E irradiation levels. The level E is defined as the incident radiation power in a receiver surface to a specific localization and relative orientation to the radiant surface expressed in units of the International System, W/m 2 or MW/cm 2 . The objective of this work is to show the measurement results for the E of a camera that contains two emitters arrangements, a first to whole body that consist of 8 lamp pairs model B17L of 160 Watts, which will have a nominal E of 358 W/m 2 (35.8 MW/cm 2 ) for UV type A and 3.3 W/m 2 (0.33 MW/cm 2 ) for UV type B; one second to face of 8 lamps model KALFASUN 630, with an E of 568 W/m 2 (56.8 MW/cm 2 ) for UV type A and 2.97 W/m 2 (0.297 MW/cm 2 ) for UV type B. The E measurements are carried out for UV-A with the body and face lamp, respectively; with two instruments: photometer mark Sportarredo, model BF01, series E009, and radiometer mark Ets without specified model. Additional the treatment time is verified with the chronometer of the digital screen of the equipment comparing it with a digital meter with resolution of 0.001 s. Conclusion: the lamps do not fulfill the E nominal values reported by the manufacturer, being minors 3.2 to 1.75 times their nominal value for the body

  3. Challenge of urban sewage disposal in a karst region: Mérida, Yucátan, Mexico

    Four hydrogeologic factors influence urban sewage management on the northern Yucátan (Mexico) Peninsula: 1) lack of rivers capable of transporting and/or oxidizing sewage, 2) near-surface flat-lying, porous, permeable limestone and dolomite with shallow layers of variable permeability but without major subsurface aquitards, 3) rapid groundwater transmission, penetration of seawater inland beneath a fresh water lens, and a flat water table only a few meters below land surface and controlled by sea level, 4) near absence of soil cover. Mérida, Yucátan (population approaching one million, approximately the world's 450th most populous city) has no central sewage system. The water table beneath the city is consistently only 7-9 m below land surface, and the 40 m-thick fresh water lens, which is the sole source of municipal, industrial, and agricultural water, directly overlies a marine intrusion of modified seawater composition. The old city has an estimated 130,000 drains feeding untreated household waste directly into the permeable karst aquifer. Numerous storm drains send street runoff directly to the aquifer. In addition, industries, hotels, and some subdivisions have unmonitored injection wells that pump untreated wastewater into the underlying saline intrusion. Some injection wells have flow problems possibly because of low aquifer permeability within the saline intrusion. Deep injection is also problematic because density contrast with saline intrusion water can produce a gravity imbalance, and high sulfate water can react with organic waste to produce H2S. Some city water supply wells are reportedly affected by inflation of the water table beneath the city, by local upconing of saline water, and by nitrate contamination. Paradoxically, Mérida with an abundant, easily contaminated source of fresh water, lacks streams to transport sewage off-site, and thus shares some water supply/sewage treatment problems with cities in arid regions.

    Mapping forest above-ground biomass (hereafter biomass) can significantly improve our ability to assess the role of forest in terrestrial carbon budget and to analyze the ecosystem productivity. Global Ecosystem Dynamic Investigation (GEDI) mission will provide the most complete lidar observations of forest vertical structure and has the potential to provide global-scale forest biomass data at 1-km resolution. However, GEDI is intrinsically a sampling mission and will have a between-track spacing of 600 m. An increase in adjacent-swath distance and the presence of cloud cover may also lead to larger gaps between GEDI tracks. In order to provide wall-to-wall forest biomass maps, fusion algorithms of GEDI lidar data and TanDEM-X InSAR data were explored in this study. Relationship between biomass and lidar RH metrics was firstly developed and used to derive biomass values over GEDI tracks which were simulated using airborne lidar data. These GEDI biomass values were then averaged in each 1-km cell to represent the biomass density within that cell. Whereas for cells without any GEDI observations, regression models developed between GEDI-derived biomass and TDX InSAR variables were applied to predict biomass over those places. Based on these procedures, contiguous biomass maps were finally generated at 1-km resolution over three representative forest types. Uncertainties for these biomass maps were also estimated at 1 km following methods developed in Saarela et al. (2016). Our results indicated great potential of GEDI/TDX fusion for large-scale biomass mapping. Saarela, S., Holm, S., Grafstrom, A., Schnell, S., Naesset, E., Gregoire, T.G., Nelson, R.F., & Stahl, G.

    2017-09-01

    Full Text Available The global Digital Elevation Model (DEM resulting from the TanDEM-X mission provides information about the world topography with outstanding precision. In fact, performance analysis carried out with the already available data have shown that the global product is well within the requirements of 10 m absolute vertical accuracy and 2 m relative vertical accuracy for flat to moderate terrain. The mission's science phase took place from October 2014 to December 2015. During this phase, bistatic acquisitions with across-track separation between the two satellites up to 3.6 km at the equator were commanded. Since the relative vertical accuracy of InSAR derived elevation models is, in principle, inversely proportional to the system baseline, the TanDEM-X science phase opened the doors for the generation of elevation models with improved quality with respect to the standard product. However, the interferometric processing of the large-baseline data is troublesome due to the increased volume decorrelation and very high frequency of the phase variations. Hence, in order to fully profit from the increased baseline, sophisticated algorithms for the interferometric processing, and, in particular, for the phase unwrapping have to be considered. This paper proposes a novel dual-baseline region-growing framework for the phase unwrapping of the large-baseline interferograms. Results from two experiments with data from the TanDEM-X science phase are discussed, corroborating the expected increased level of detail of the large-baseline DEMs.

    Tanning sludge enriched with high concentrations of Cr and other metals has adverse effects on the environment. Plants growing in the metalliferous soils may have the ability to cope with high metal concentrations. This study focuses on potentials of using native plants for bioindication and/or phytoremediation of Cr-contaminated sites. In the study, we characterized plants and soils from six tanning sludge storage sites. Soil in these sites exhibited toxic levels of Cr (averaged 16,492 mg kg -1 ) and other metals (e.g., 48.3 mg Cu kg -1 , 2370 mg Zn kg -1 , 44.9 mg Pb kg -1 , and 0.59 mg Cd kg -1 ). Different metal tolerance and accumulation patterns were observed among the sampled plant species. Phragmites australis, Zephyranthes candida, Cynodon dactylon, and Alternanthera philoxeroides accumulated moderate-high concentrations of Cr and other metals, which could make them good bioindicators of heavy metal pollution. High Cr and other metal concentrations (e.g., Cd and Pb) were found in Chenopodium rubrum (372 mg Cr kg -1 ), Aster subulatus (310 mg Cr kg -1 ), and Brassica chinensis (300 mg Cr kg -1 ), being considered as metal accumulators. In addition, Nerium indicum and Z. candida were able to tolerate high concentrations of Cr and other metals, and they may be used as preferable pioneer species to grow or use for restoration in Cr-contaminated sites. This study can be useful for establishing guidelines to select the most suitable plant species to revegetate and remediate metals in tanning sludge-contaminated fields.

  14. Application of Bistatic TanDEM-X Interferometry to Measure Lava Flow Volume and Lava Extrusion Rates During the 2012-13 Tolbachik, Kamchatka Fissure Eruption

    Aerial imaging methods are a well approved source for mapping lava flows during eruptions and can serve as a base to assess the eruption dynamics and to determine the affected area. However, clouds and smoke often hinder optical systems like the Earth Observation Advanced Land Imager (EO-1-ALI, operated by NASA) to map lava flows properly, which hence affects its reliability. Furthermore, the amount of lava that is extruded during an eruption cannot be determined from optical images - however, it can significantly contribute to assess the accompanying hazard and risk. One way to monitor active lava flows is to quantify the topographic changes over time while using up-to-date high-resolution digital elevation models (DEMs). Whereas photogrammetric methods still fail when clouds and fume obstruct the sight, innovative radar satellite missions have the potential to generate high-resolution DEMs at any time. The innovative bistatic TanDEM-X (TerraSAR-X Add-on for Digital Elevation Measurements) satellite mission enables for the first time generating high-resolution DEMs from synthetic aperture radar satellite data repeatedly with reasonable costs and high resolution. The satellite mission consists of the two nearly identical satellites TerraSAR-X and TanDEM-X that build a large synthetic aperture radar interferometer with adaptable across- and along-track baselines aiming to generate topographic information globally. In the present study, we apply the TanDEM-X data to study the lava flows that were emplaced during the 2012-13 Tolbachik, Kamchatka fissure eruption. The eruption was composed of very fluid lava flows that effused along a northeast-southwest trending fissure. We used about fifteen bistatic data pairs to generate DEMs prior to, during, and after the eruption. The differencing of the DEMs enables mapping the lava flow field at different times. This allows measuring the extruded volume and to derive the changes in lava extrusion over time.

    Rye ( Secale cereale L.) serves as an alternative host of Pyrenophora tritici-repentis ( PTR ) the cause of tan spot on wheat. Rye is cultivated as a forage or cover crop and overlaps with a significant portion of wheat acreage in the U.S. northern Great Plains; however, it is not known whether the rye crop influences the evolution of PTR races. We evaluated a global collection of 211 rye accessions against tan spot and assessed the diversity in PTR population on rye in South Dakota. All the rye genotypes were inoculated with PTR races 1 and 5, and infiltrated with Ptr ToxA and Ptr ToxB, at seedling stage. We observed 21% of the genotypes exhibited susceptibility to race 1, whereas, 39% were susceptible to race 5. All 211 accessions were insensitive to both the Ptr toxins. It indicates that though rye exhibits diversity in reaction to tan spot, it lacks Ptr ToxA and ToxB sensitivity genes. This suggests that unknown toxins or other factors can lead to PTR establishment in rye. We characterized the race structure of 103 PTR isolates recovered from rye in South Dakota. Only 22% of the isolates amplified Ptr ToxA gene and were identified as race 1 based on their phenotypic reaction on the differential set. The remaining 80 isolates were noted to be race 4. Our results show that races 1 and 4 are prevalent on rye in South Dakota with a higher frequency of race 4, suggesting a minimal role of rye in the disease epidemiology.

  17. Enhancement of Endurance in HfO2-Based CBRAM Device by Introduction of a TaN Diffusion Blocking Layer

    2017-08-05

    We propose a new method to improve resistive switching properties in HfO2 based CBRAM crossbar structure device by introducing a TaN thin diffusion blocking layer between the Cu top electrode and HfO2 switching layer. The Cu/TaN/HfO2/TiN device structure exhibits high resistance ratio of OFF/ON states without any degradation in switching during endurance test. The improvement in the endurance properties of the Cu/TaN/HfO2/TiN CBRAM device is thus attributed to the relatively low amount of Cu migration into HfO2 switching layer.

  20. Highly uniform ultraviolet-A quantum-confined AlGaN nanowire LEDs on metal/silicon with a TaN interlayer

    2017-11-02

    In this paper, we describe ultraviolet-A (UV-A) light-emitting diodes (LEDs) emitting at 325 nm based on a highly uniform structure of quantum-confined AlGaN quantum-disk nanowires (NWs). By incorporating a 20 nm TaN interlayer between a Ti pre-orienting layer and the silicon substrate, we eliminated the potential barrier for carrier injection and phonon transport, and inhibited the formation of interfacial silicide that led to device failure. Compared to previous reports on metal substrate, we achieved a 16 × reduction in root-mean-square (RMS) roughness, from 24 nm to 1.6 nm, for the samples with the Ti/TaN metal-bilayer, owing to the effective diffusion barrier characteristic of TaN. This was confirmed using energy dispersive X-ray spectroscopy (EDXS) and electron energy loss spectroscopy (EELS). We achieved a considerable increase in the injection current density (up to 90 A/cm2) compared to our previous studies, and an optical power of 1.9 μW for the 0.5 × 0.5 mm2 NWs-LED. This work provides a feasible pathway for both a reliable and stable UV-A device operation at elevated current injection, and eventually towards low-cost production of UV devices, leveraging on the scalability of silicon substrates.

    The thermal decomposition of chrome tanned leather before and after a soaking treatment with NaOH was studied using thermogravimetric analysis (TGA). The effect of the solution concentration (0.2M and 0.5M) and the soaking time (5min and 15min) was evaluated. TGA experiments at four heating rates (5, 10, 15 and 20°Cmin(-1)) were run in a nitrogen atmosphere for every treatment condition. A kinetic model was developed considering the effect of the three variables studied, i.e.: the NaOH solution concentration, the soaking time and the heating rate. The proposed model for chrome tanned leather pyrolysis involves a set of four reactions, i.e.: three independent nth order reactions, yielding the corresponding products and one of them undergoing a successive cero order reaction. The model was successfully applied simultaneously to all the experimental data obtained. The evaluation of the kinetic parameters obtained (activation energy, pre-exponential factor and reaction order) allowed a better understanding of the effect of the alkali treatment on these wastes.

    Full Text Available Aerosol scattering is an important source of error in CO2 retrievals from satellite. This paper presents an analysis of aerosol information content from the Cloud and Aerosol Polarimetric Imager (CAPI onboard the Chinese Carbon Dioxide Observation Satellite (TanSat to be launched in 2016. Based on optimal estimation theory, aerosol information content is quantified from radiance and polarization observed by CAPI in terms of the degrees of freedom for the signal (DFS. A linearized vector radiative transfer model is used with a linearized Mie code to simulate observation and sensitivity (or Jacobians with respect to aerosol parameters. In satellite nadir mode, the DFS for aerosol optical depth is the largest, but for mode radius, it is only 0.55. Observation geometry is found to affect aerosol DFS based on the aerosol scattering phase function from the comparison between different viewing zenith angles or solar zenith angles. When TanSat is operated in target mode, we note that multi-angle retrieval represented by three along-track measurements provides additional 0.31 DFS on average, mainly from mode radius. When adding another two measurements, the a posteriori error decreases by another 2%–6%. The correlation coefficients between retrieved parameters show that aerosol is strongly correlated with surface reflectance, but multi-angle retrieval can weaken this correlation.

    We developed a process model LM3-TAN to assess the combined effects of direct human influences and climate change on terrestrial and aquatic nitrogen (TAN) cycling. The model was developed by expanding NOAA's Geophysical Fluid Dynamics Laboratory land model LM3V-N of coupled terrestrial carbon and nitrogen (C-N) cycling and including new N cycling processes and inputs such as a soil denitrification, point N sources to streams (i.e., sewage), and stream transport and microbial processes. Because the model integrates ecological, hydrological, and biogeochemical processes, it captures key controls of the transport and fate of N in the vegetation–soil–river system in a comprehensive and consistent framework which is responsive to climatic variations and land-use changes. We applied the model at 1/8° resolution for a study of the Susquehanna River Basin. We simulated with LM3-TAN stream dissolved organic-N, ammonium-N, and nitrate-N loads throughout the river network, and we evaluated the modeled loads for 1986–2005 using data from 16 monitoring stations as well as a reported budget for the entire basin. By accounting for interannual hydrologic variability, the model was able to capture interannual variations of stream N loadings. While the model was calibrated with the stream N loads only at the last downstream Susquehanna River Basin Commission station Marietta (40°02' N, 76°32' W), it captured the N loads well at multiple locations within the basin with different climate regimes, land-use types, and associated N sources and transformations in the sub-basins. Furthermore, the calculated and previously reported N budgets agreed well at the level of the whole Susquehanna watershed. Here we illustrate how point and non-point N sources contributing to the various ecosystems are stored, lost, and exported via the river. Local analysis of six sub-basins showed combined effects of land use and climate on soil denitrification rates, with the highest rates in the

    Using scanning electron microscopy (SEM) and high-resolution x-ray photoelectron spectroscopy with the synchrotron radiation we investigated Si-based micro-clusters embedded in TaSiN thin films having oxygen contamination. TaSiN thin films were deposited by co-sputtering on fixed or rotated substrates and with various power conditions of TaN and Si targets. Three types of embedded micro-clusters with the chemical states of pure Si, SiO{sub x}-capped Si, and SiO{sub 2}-capped Si were observed and analyzed using SEM and Si 2p and Ta 4f core-level spectra were derived. Their different resistivities are presumably due to the different chemical states and densities of Si-based micro-clusters.

    2004-01-01

    One of the main physics goals of the Large Hadron Collider is the search of particles predicted by supersymmetric theories. This study analyses the possibility of using kinematic endpoints of mass spectra for a sparticle mass reconstruction. It focuses on cascade decays, which include the second-lightest neutralino, in the mSUGRA framework with tan(b) = 35, A0 = 0 and positive mu. A region of 25 points around the benchmark point I' with m0 = 181 and m1/2 = 350 is chosen, where the cascade decay of the second-lightest neutralino into two opposite-sign taus and the lightest neutralino has a branching ratio of over 95%. Two methods of measuring 13 kinematic limits are tested systematically at Monte Carlo generator level.

    Full Text Available Background Vitamin D is a key nutrient in bone health and the vitamin D status of individuals with regular exposure to solar or artificial ultraviolet B (UVB radiation is generally superior to those with limited exposure. Objective By means of a cross-sectional, observational design, explore the association of serum 25-hydroxy vitamin D (25(OHD concentrations and biochemical markers of bone turnover across a spectrum of vitamin D status by comparing women who regularly use tanning beds with women of minimal UVB exposure. Methods A total of 69 healthy women, ages 25–82 y, were recruited. Serum concentrations of 25(OHD, intact parathyroid hormone (iPTH, leptin, bone-specific alkaline phosphatase (BAP, osteocalcin (OC, and C-terminal telopeptides of Type I collagen (CTx were measured. Results There were no significant differences in age, height, weight, BMI and dietary intakes between groups. Serum 25(OHD concentrations were significantly higher in tanners (n = 20 compared with non-tanners (n = 49 (p < 0.0001. Serum iPTH concentrations were lower in tanners than in non-tanners (p < 0.0001 and were negatively correlated with serum 25(OHD concentrations (r = – 4571, p < 0.0001. Of the bone turnover markers, only serum OC concentrations were lower in tanners compared with non-tanners (p = 0.0002. After adjusting for age and menopausal status, osteocalcin was negatively correlated (r = – 0.0178; p = 0.04 with 25(OHD and positively correlated with iPTH (r = 0.035; p = 0.05. Conclusions Our results show healthy women with regular UVB exposure via tanning beds have significantly greater vitamin D status and lower serum osteocalcin concentrations than those without and that there is a significant inverse relationship between serum serum 25(OHD and osteocalcin concentrations which appears to be PTH-dependent.

    Heavy polar molecules have been used for some time in experiments designed to measure the permanent molecular electric dipole moment, EDM, that is induced by the electron electric dipole moment, eEDM. More recently, ^{181}TaN has been proposed as a prime candidate for experiments to measure the EDM induced by the magnetic quadrupole moment, MQM, of the nucleus. There have been a number of calculations to predict these quantities and hyperfine structure parameters are useful indicators of the quality of the electronic wavefunctions used in these calculations with the low-lying a^{3}Δ_{1} state being of particular interest. High resolution Laser Induced Fluorescence (LIF) spectra of the of the 0-0 band of the [15.45]0 - a^{3}Δ_{1} transition of TaN have been obtained using the laser ablation source at Arizona State University. Tantalum hyperfine structure was completely resolved and magnetic and quadrupole hyperfine parameters were determined and, where available, have been compared with predicted values. Calculations of the molecular hyperfine constants using atomic hyperfine parameters have been used to determine the nature and configurations of the electronic states. V.V. Flambaum, D. DeMille, M.G.

    Full Text Available El presente trabajo se inserta en el campo de estudios sobre juventud y política, entendida esta última como aspecto clave del vínculo con el "proyecto común" al que los jóvenes se suman formalmente como nuevos ciudadanos. Desde una perspectiva psicosocial y con foco en el contexto contemporáneo argentino, el artículo problematiza la relación entre cómo conciben los jóvenes a "la ciudadanía" en un plano ideal y cómo son sus actitudes como ciudadanos en-situación, con especial interés en las tensiones y articulaciones entre la moral y la política, lo individual y lo social. En esta línea, se presentan y analizan resultados de un estudio realizado en Argentina entre el 2011-3 con jóvenes estudiantes (N=275 en el cual se indaga, por una parte, sus modelos de ciudadanía y, por otra, sus propuestas para abordar la llamada "inseguridad", una problemática percibida por ellos como central y actual, enfrentándolos a una alta conflictividad social. Como resultado, se establecen tres ideal/es de ciudadano (individual, social y político y tres tipos de posicionamiento subjetivo (punitivo, disciplinar y político, que se infieren a partir de sus propuestas para abordar "la inseguridad". Se concluye problematizando y reflexionando sobre la correlación hallada en la mayoría de los participantes entre el ideal individual del ciudadano, con fuerte impronta moral, y el posicionamiento punitivo frente al conflicto, y remarcando la necesidad de trabajar en pos de la incorporación de la dimensión social y política al pensamiento de los jóvenes.

    As part of the Ring of Fire, Shiveluch volcano is one of the largest and most active volcanoes on Kamchatka Peninsula. During the Holocene, only the southern part of the Shiveluch massive was active. Since the last Plinian eruption in 1964, the activity of Shiveluch is characterized by periods of dome growth and explosive eruptions. The recent active phase began in 1999 and continues until today. Due to the special conditions at active volcanoes, such as smoke development, danger of explosions or lava flows, as well as poor weather conditions and inaccessible area, it is difficult to observe the interaction between dome growth, dome destruction, and explosive eruptions in regular intervals. Consequently, a reconstruction of the eruption processes is hardly possible, though important for a better understanding of the eruption mechanism as well as for hazard forecast and risk assessment. A new approach is provided by the bistatic radar data acquired by the TanDEM-X satellite mission. This mission is composed of two nearly identical satellites, TerraSAR-X and TanDEM-X, flying in a close helix formation. On one hand, the radar signals penetrate clouds and partially vegetation and snow considering the average wavelength of about 3.1 cm. On the other hand, in comparison with conventional InSAR methods, the bistatic radar mode has the advantage that there are no difficulties due to temporal decorrelation. By interferometric evaluation of the simultaneously recorded SAR images, it is possible to calculate high-resolution digital elevation models (DEMs) of Shiveluch volcano and its surroundings. Furthermore, the short recurrence interval of 11 days allows to generate time series of DEMs, with which finally volumetric changes of the dome and of lava flows can be determined, as well as lava effusion rates. Here, this method is used at Shiveluch volcano based on data acquired between June 2011 and September 2014. Although Shiveluch has a fissured topography with steep slopes

    Full Text Available Mangrove forests are important natural ecosystems due to their ability to capture and store large amounts of carbon. Forest structural parameters, such as canopy height and above-ground biomass (AGB, provide a good measure for monitoring temporal changes in carbon content. The protected coastal mangrove forest of the Everglades National Park (ENP provides an ideal location for studying these processes, as harmful human activities are minimal. We estimated mangrove canopy height and AGB in the ENP using Airborne LiDAR/Laser (ALS and TanDEM-X (TDX datasets acquired between 2011 and 2013. Analysis of both datasets revealed that mangrove canopy height can reach up to ~25 m and AGB can reach up to ~250 Mg•ha−1. In general, mangroves ranging from 9 m to 12 m in stature dominate the forest canopy. The comparison of ALS and TDX canopy height observations yielded an R2 = 0.85 and Root Mean Square Error (RMSE = 1.96 m. Compared to a previous study based on data acquired during 2000–2004, our analysis shows an increase in mangrove stature and AGB, suggesting that ENP mangrove forests are continuing to accumulate biomass. Our results suggest that ENP mangrove forests have managed to recover from natural disturbances, such as Hurricane Wilma.

    Differential expression of the ASIP gene and its interaction with MC1R have provided basic insight into pigment-type switching in mammals. Here, we report the characterization of a specific red-haired skin transcript and a specific black-haired skin transcript in the ASIP gene in the black-and-tan Doberman Pinscher. It is also shown that the brindle-haired skin of the Boxer exhibits a deregulated expression resulting in various 5'-untranslated exons. Comparative sequence analysis revealed a short interspersed element and a poly(A) stretch inserted within the promoter region of the ASIP in the Boxer. Genotyping studies have shown that both insertions are also present in brindle and fawn animals of the Boxer and Great Dane breeds. Furthermore, we genotyped MC1R and K loci for their known variants that affect coat color in dogs. As expected, all animals were homozygotes (E(M) /E(M) ) for the mask mutation, and fawn animals were k(y) /k(y) . Unexpectedly, we found that all brindle animals were heterozygotes k(B) /k(y) . Our results suggest that differential expression of ASIP determine pigment-type switching in a MC1R and K allele-dependent manner in dogs. © 2012 The Authors, Animal Genetics © 2012 Stichting International Foundation for Animal Genetics.

    The health belief model (HBM) has been widely used to inform health education, social marketing, and health communication campaigns. Although the HBM can explain and predict an individual's willingness to engage in positive health behaviors, its application to, and penetration of the underlying constructs into, mass media content has not been well characterized. We examined 574 articles and 905 images about skin cancer and tanning risks, behaviors, and screening from 20 U.S. women's and men's magazines (2000-2012) for the presence of HBM constructs: perceived susceptibility, perceived severity, perceived benefits, perceived barriers, self-efficacy, and cues to action. Susceptibility (48.1%) and severity (60.3%) information was common in text. Perceived benefits (36.4%) and barriers (41.5%) to prevention of skin cancer were fairly equally mentioned in articles. Self-efficacy (48.4%) focused on sunscreen use. There was little emphasis on HBM constructs related to early detection. Few explicit cues to action about skin cancer appeared in text (12.0%) or images (0.1%). HBM constructs were present to a significantly greater extent in text versus images (e.g., severity, 60.3% vs. 11.3%, respectively, χ(2) = 399.51, p < .0001; benefits prevention, 36.4% vs. 8.0%, respectively, χ(2) = 184.80, p < .0001), suggesting that readers are not visually messaged in ways that would effectively promote skin cancer prevention and early detection behaviors.

    Full Text Available Tan spot (TS, caused by the fungus Pyrenophora tritici-repentis (Died Drechs, is an important foliar disease of wheat and has become a threat to world wheat production since the 1970s. In this study a globally diverse pre-1940s collection of 247 wheat genotypes was evaluated against Ptr ToxA, P. tritici-repentis race 1, and stem rust to determine if; (i acquisition of Ptr ToxA by the P. tritici-repentis from Stagonospora nodorum led to increased pathogen virulence or (ii incorporation of TS susceptibility during development stem rust resistant cultivars led to an increase in TS epidemics globally. Most genotypes were susceptible to stem rust; however, a range of reactions to TS and Ptr ToxA were observed. Four combinations of disease-toxin reactions were observed among the genotypes; TS susceptible-Ptr ToxA sensitive, TS susceptible-Ptr ToxA insensitive, TS resistant-Ptr ToxA insensitive, and TS resistant-Ptr ToxA toxin sensitive. A weak correlation (r = 0.14 for bread wheat and −0.082 for durum was observed between stem rust susceptibility and TS resistance. Even though there were no reported epidemics in the pre-1940s, TS sensitive genotypes were widely grown in that period, suggesting that Ptr ToxA may not be an important factor responsible for enhanced prevalence of TS.

    2017-10-01

    Full Text Available The main aim of this article is to show how Gaétan Soucy’s 1998 bestselling novel The Little Girl Who Was Too Fond of Matches both extends and complicates the Canadian Gothic tradition. The first part focuses on Canada as a “haunted culture,” and attempts to identify the ghosts which haunt Canada and make themselves manifest in the nation’s gothic literature. I ponder the postcolonial character of Canadian Gothic, and reflect on the representations of monstrous nature in Canada’s early fiction. A short section is devoted to the characteristics of French-Canadian Gothic. The second part of my article proposes a reading of Soucy’s novel which concentrates on gothic transgressions the story revolves around. One of my assumptions is that the novel invites ecocritical and ecofeminist interpretations, and that its representations of nature also reveal the subversive character of the text whose narrator, by her own admission, locates herself on the threshold of things.

    This study demonstrates the potential of using single-pass TanDEM-X (TDX) radar imagery to analyse inter- and intra-annual glacier changes in mountainous terrain. Based on SAR images acquired in February 2012, March 2013 and November 2013 over the Inylchek Glacier, Kyrgyzstan, we discuss in detail the processing steps required to generate three reliable digital elevation models (DEMs) with a spatial resolution of 10 m that can be used for glacial mass balance studies. We describe the interferometric processing steps and the influence of a priori elevation information that is required to model long-wavelength topographic effects. We also focus on DEM alignment to allow optimal DEM comparisons and on the effects of radar signal penetration on ice and snow surface elevations. We finally compare glacier elevation changes between the three TDX DEMs and the C-band shuttle radar topography mission (SRTM) DEM from February 2000. We introduce a new approach for glacier elevation change calculations that depends on the elevation and slope of the terrain. We highlight the superior quality of the TDX DEMs compared to the SRTM DEM, describe remaining DEM uncertainties and discuss the limitations that arise due to the side-looking nature of the radar sensor.

    Increased impervious surfaces pose significant threats to the hydrologic cycle of the Xiangjiang River basin as a consequence of urbanization. Quantifying the percentage of imperviousness within the Xiangjiang River basin is important to pollution control and watershed management. Per-pixel and sub-pixel methods have been widely used for analyzing impervious surface changes, but these methods are considered as complicated, computationally intensive, and sometimes subjective, especially when applied to a large geographic area. In this paper, normalized difference built-up index (NDBI), normalized difference impervious surface index (NDISI), normalized difference vegetation index (NDVI) and enhanced built-up and bareness index (EBBI) were respectively used to estimate impervious surfaces in Chang-ZhuTan region (CZT) of the Xiangjiang River basin, and a comparative analyses was conducted. Then the optimum spectral index was chosen to map the percentage of impervious surfaces for the study area. The results show that the spectral index of NDBI has the optimum estimation of large-scale impervious surfaces, and the percentage of imperviousness in CZT was 13.87%. The water quality in CZT was characterized as "protected", indicating that water quality protection in the plain areas of CZT is imperative.

    "Dyeing" is a common practice used to color the hides during the post-tanning operations in leather processing generating plenty of wastewater. The waste stream containing dye as pollutant is severely harmful to living beings. An azo dye (C.I. Acid Blue 113) has been biodegraded effectively by bacterial culture mediated with azoreductase enzyme to reduce the pollution load in the present investigation. The maximum rate of dye degradation was found to be 96 ± 4 and 92 ± 4 % for the initial concentrations of 100 and 200 mg/l, respectively. The enzyme activity was measured using NADH as a substrate. Fourier transform infrared spectroscopy (FT-IR) analysis was confirmed that the transformation of azo linkage could be transformed into N2 or NH3 or incorporated into complete biomass. Breaking down of dye molecules to various metabolites (such as aniline, naphthalene-1,4-diamine, 3-aminobenzenesulfonic acid, naphthalene-1-sulfonic acid, 8-aminonaphthalene-1-sulfonic acid, 5,8-diaminonaphthalene-1-sulfonic acid) was confirmed by gas chromatography and mass spectra (GC-MS) and mass (electrospray ionization (ESI)) spectra analysis. The treated wastewater could be reused for dyeing operation in the leather processing, and the properties of produced leather were evaluated by conventional methods that revealed to have improved dye penetration into the grain layer of experimental leather sample and resulted in high levelness of dyeing, which helps to obtain the desired smoothness and soft leather properties.

    This article considers the effects of ultraviolet (UV) light from the sun and UV-A sun beds on the skin. Sun worshipping and sun therapy has been en vogue for centuries, but in another way than used today. A changing lifestyle has led to an increase of various skin diseases, including skin cancer. Short wave UV-light (UV-B) in particular has been blamed for inducing not only erythema and pigmentation but also more chronic skin lesions. Long wave UV-light (UV-A) has been shown to be the cause of similar changes to the skin but the pigmentation is of another quality and affords less protection against the harmful effects of UV-B. A concept of sun reactive skin typing has been created. This is based on self-reported responses to an initial exposure to sun as regards tanning ability and erythema reaction. These two factors have certain practical consequences, not only for UV-phototherapy but also for a person's risk of developing skin cancer. Recently, several research groups and dermatologists have discouraged extensive use of UV-A sun beds because of side effects of varying degrees of seriousness. The possible implications of these side effects for the organism are not fully elucidated and may be more profound than known today. The British Photodermatology Group has issued more stringent rules for persons who, despite advice to the contrary, still wish to use UV-A sun beds. 14 refs., 1 tab.

    Tan spot (TS), caused by the fungus Pyrenophora tritici-repentis (Died) Drechs, is an important foliar disease of wheat and has become a threat to world wheat production since the 1970s. In this study a globally diverse pre-1940s collection of 247 wheat genotypes was evaluated against Ptr ToxA, P. tritici-repentis race 1, and stem rust to determine if; (i) acquisition of Ptr ToxA by the P. tritici-repentis from Stagonospora nodorum led to increased pathogen virulence or (ii) incorporation of TS susceptibility during development stem rust resistant cultivars led to an increase in TS epidemics globally. Most genotypes were susceptible to stem rust; however, a range of reactions to TS and Ptr ToxA were observed. Four combinations of disease-toxin reactions were observed among the genotypes; TS susceptible-Ptr ToxA sensitive, TS susceptible-Ptr ToxA insensitive, TS resistant-Ptr ToxA insensitive, and TS resistant-Ptr ToxA toxin sensitive. A weak correlation (r = 0.14 for bread wheat and -0.082 for durum) was observed between stem rust susceptibility and TS resistance. Even though there were no reported epidemics in the pre-1940s, TS sensitive genotypes were widely grown in that period, suggesting that Ptr ToxA may not be an important factor responsible for enhanced prevalence of TS.

  7. A search for neutral Higgs bosons at high tan beta in multi-jet events from p anti-p collisions at √s = 1960-GeV

    The Higgs mechanism preserves the gauge symmetries of the Standard Model while giving masses to the W, Z bosons. Supersymmetry, which protects the Higgs boson mass scale from quantum corrections, predicts at least 5 Higgs bosons, none of which has been directly observed. This thesis presents a search for neutral Higgs bosons, produced in association with bottom quarks. The production rate is greatly enhanced at large values of the Supersymmetric parameter tan β. High-energy p$\\bar{p}$ collision data, collected from Run II of the Fermilab Tevatron using the D0 detector, are analyzed. In the absence of a signal, values of tan β > 80-120 are excluded at 95% Confidence Level (C.L.), depending on the (CP-odd) neutral Higgs boson mass (studied from 100 to 150 GeV/c2).

    Full Text Available Bearing in mind the adverse health effects of exposure to ultraviolet (UV radiation in solarium, especially the risk of carcinogenesis, there is a need to adopt legal regulations by relevant Polish authorities. They should set out the principles for indoor tanning studios operation, supervision and service of the technical parameters of tanning devices and training programs to provide the staff with professional knowledge and other aspects of safety in these facilities. The mechanism of the harmful effects of ultraviolet radiation on the human body, scale of overexposure, resulting from excessive sunbathing are described. Methods for estimating UV exposure and possible actions aimed at reducing the overexposure and preventing from cancer development caused by UV are also presented in this paper.

    Full Text Available The vaccinia virus TianTan (VTT has been modified as an HIV vaccine vector in China and has shown excellent performance in immunogenicity and safety. However, its adverse effects in immunosuppressed individuals warrant the search for a safer vector in the following clinic trails. In this study, we deleted the C7L and K1L genes of VTT and constructed six recombinant vaccinia strains VTT△C7L, VTT△K1L, VTT△C7LK1L, VTKgpe△C7L, VTKgpe△K1L and VTT△C7LK1L-gag. The pathogenicity and immunogenicity of these recombinants were evaluated in mouse and rabbit models. Comparing to parental VTT, VTT△C7L and VTT△K1L showed significantly decreased replication capability in CEF, Vero, BHK-21 and HeLa cell lines. In particular, replication of VTT△C7LK1L decreased more than 10-fold in all four cell lines. The virulence of all these mutants were decreased in BALB/c mouse and rabbit models; VTT△C7LK1L once again showed the greatest attenuation, having resulted in no evident damage in mice and erythema of only 0.4 cm diameter in rabbits, compared to 1.48 cm for VTT. VTKgpe△C7L, VTKgpe△K1L and VTT△C7LK1L-gag elicited as strong cellular and humoral responses against HIV genes as did VTKgpe, while humoral immune response against the vaccinia itself was reduced by 4-8-fold. These data show that deletion of C7L and K1L genes leads to significantly decreased virulence without compromising animal host immunogenicity, and may thus be key to creating a more safe and effective HIV vaccine vector.

    Full Text Available Microspore embryogenesis is a method of achieving complete homozygosity from plants. It is particularly useful for woody species, like Citrus, characterized by long juvenility, a high degree of heterozygosity and often self-incompatibility. Anther culture is currently the method of choice for microspore embryogenesis in many crops. However, isolated microspore culture is a better way to investigate the processes at the cellular, physiological, biochemical and molecular levels as it avoids the influence of somatic anther tissue. To exploit the potential of this technique, it is important to separate the key factors affecting the process and, among them, culture medium composition and particularly the plant growth regulators and their concentration, as they can greatly enhance regeneration efficiency. To our knowledge, the ability of meta-Topolin, a naturally occurring aromatic cytokinin, to induce gametic embryogenesis in isolated microspores of Citrus has never been investigated. In this study, the effect of two concentrations of meta-Topolin instead of benzyladenine or zeatin in the culture medium was investigated in isolated microspore culture of two genotypes of Citrus. After eleven months of isolated microspore culture, for both genotypes and for all the four tested media, the microspore reprogramming and their sporophytic development was observed by the presence of multinucleated calli and microspore-derived embryos at different stages. Microsatellite analysis of parental and embryo samples was performed to determine the embryo alleles constitution of early embryos produced in all tested media, confirming their origin from microspores.To our knowledge, this is the first successful report of Citrus microspore embryogenesis with isolated microspore culture in Citrus, and in particular in Citrus clementina Hort. ex Tan, cvs. ‘Monreal Rosso’ and ‘Nules’.

    As the largest strike-slip fault system in eastern China, the northeast-trending Tan-Lu Fault Zone (TLFZ) is a significant tectonic element contributing to the Mesozoic-Cenozoic regional geologic evolution of eastern Asia, as well as to the formation of ore deposits and oilfields. Because of the paucity of data, its distribution and evolutionary history in the offshore Liaohe sub-basin of the northern Bohai Bay Basin (BBB) are still poorly understood. Investigations of the strike-slip fault system in the western portion of the offshore Liaohe sub-basin via new seismic data provide us with new insights into the characteristics of the Cenozoic TLFZ. Results of this study show that Cenozoic dextral strike-slip faults occurred near the center of the Liaoxi graben in the offshore Liaohe sub-basin; these strike-slip faults connect with their counterparts to the north, the western part of the onshore Liaohe sub-basin, and have similar characteristics to those in other areas of the BBB in terms of kinematics, evolutionary history, and distribution; consequently, these faults are considered as the western branch of the TLFZ. All strike-slip faults within the Liaoxi graben merge at depth with a central subvertical basement fault induced by the reactivation of a pre-existing strike-slip basement fault, the pre-Cenozoic TLFZ. Data suggest that the TLFZ across the whole Liaohe sub-basin comprises two branches and that the Cenozoic distribution of this system was inherited from the pre-Cenozoic TLFZ. This characteristic distribution might be possessed by the whole TLFZ, thus the new understandings about the distribution and evolutionary model of the TLFZ in this study can be inferred in many research fields along the whole fault zone, such as regional geology, ore deposits, petroleum exploration and earthquake hazard.

  12. Ice shelf melt rates in Greenland and Antarctica using time-tagged digital imagery from World View and TanDEM-X

    The floating extensions of glaciers, or ice shelves, melt vigorously in contact with ocean waters. Melt is non uniform, with the highest melt taking place in the deepest part of the cavity, where thermal forcing is the greatest because of 1) the pressure dependence of the freezing point of the seawater/ice mixture and 2) subglacial water injects fresh, buoyant, cold melt water to fuel stronger ice-ocean interactions. Melt also forms along preferential channels, which are not stationary, and create lines of weakness in the shelf. Ice shelf melt rates have been successfully measured from space over the entire Antarctic continent and on the ice shelves in Greenland using an Eulerian approach that combines ice thickness, ice velocity vectors, surface mass balance data, and measurements of ice thinning rates. The Eulerian approach is limited by the precision of the thickness gradients, typically of a few km, and requires significant spatial averaging to remove advection effects. A Lagrangian approach has been shown to be robust to advection effects and provides higher resolution details. We implemented a Lagrangian methodology for time-tagged World View DEMs by the Polar Geoscience Center (PGS) at the University of Minnesota and time-tagged TanDEM-X DEMs separated by one year. We derive melt rates on a 300-m grid with a precision of a few m/yr. Melt is strongest along grounding lines and along preferred channels. Channels are non-stationary because melt is not the same on opposite sides of the channels. Examining time series of data and comparing with the time-dependent grounding line positions inferred from satellite radar interferometry, we evaluate the magnitude of melt near the grounding line and even within the grounding zone. A non-zero melt rate in the grounding zone has vast implications for ice sheet modeling. This work is funded by a grant from NASA Cryosphere Program.

    The Babesia species "BQ1 (Lintan)" is infective to sheep and goats. The species was isolated from Haemaphysalis qinghaiensis collected in the Gannan Tibet Autonomous Region, China in April 2000. In this study, an in vitro culture system was developed for the propagation of Babesia sp. BQ1 (Lintan). Continuous cultivation and 5.0% parasitemia was obtained in vitro in RPMI 1640 medium with sheep red blood cells (RBC) (7.5%) supplemented with Fetal Bovine Serum (FBS) (20%), Amphotericin B (0.5 microg/ml) and Gentamicin (50 microg/ml) in an incubator at 37 degrees C and 6% CO(2) in 24-well and 6-well plates. Parasitemia could attain 10% in 75 cm(2) flasks with the same culture medium but with 2.5% RBC. A clonal line of Babesia sp. BQ1 (Lintan) was screened using the limiting dilution method and designated G7. Growth of Babesia sp. BQ1 (Lintan) in vitro was measured by microtitre-based spectrophotometric method and from parasitemia counts. The generation time was between 20.57 h (based the A(405) of the culture supernatant) and 26.41 h (based on parasitemia). Three French sheep were successfully infected with the culture and the infectivity of the clonal line G7 was determined. Finally, this in vitro culture system was used to compare the susceptibility (capacity to sustain Babesia sp. growth in vitro) of RBC from French sheep (Vendéen breed) and Chinese sheep (Tan mutton breed) for Babesia sp. BQ1 (Lintan) and B. divergens. The lower susceptibility to B. divergens and Babesia sp. BQ1 (Lintan) of RBC from French sheep, compared to Chinese sheep, is discussed. (c) 2010 Elsevier B.V.

    Full Text Available Isidoro de Sevilla en su obra maestra Etimologías, supo unir el “origen”, o sea, de dónde viene un vocablo y la “etimología”, que sería el “por qué” se aplica este vocablo a una realidad concreta. Hizo, pues, una distinción entre etimologías ex causa (según lo que es y etimologías ex origine (según de dónde viene. Y, como de lo que se trataba era decaptar el valor esencial de una palabra, dice Isidoro, “cuando se ha visto de dónde viene un nombre, se comprende más rápidamente su valor, porque el estudio de las realidades es más fácil una vez conocida la etimología” (Etimologías, I, 19, 2. Siguiendo en parte esta orientación, presentamos algunas raíces de verbos griegos, lejanos en referencia al tiempo de su origen, pero presentes en nuestro tiempo a través de sus derivaciones. Y, sobre todo persistentes, porque nos transmiten la esencia de significado, ladensidad semántica, a la que he aludido en varias ocasiones1.De esta forma, el hoy de muchas de nuestras palabras está impregnado de este pasado clásico que nos invita a recuperar permanentemente su esencia.

    Full Text Available There is ample evidence that the environment is in serious danger. The problem posed by environmental degradation is a very complex one and it depends on both ecological and human-related factors. The understanding of the relationship between environmental and social systems is, therefore, key in order to design strategies and public policies addressing environmental problems. The objective of this paper is analyzing the issue of environmental degradation, as well as illustrating the contributions made by ecological economics and, concretely, a branch of it that uses measures of subjective wellbeing, in the search for solutions to environmental problems. Studies on wellbeing suggest that environmental degradation has a very negative effect on subjective well-being. Besides, preoccupation about environmental degradation itself has also a negative effect on people’s happiness. Moreover, environmental responsible behaviors have been found to show a positive relationship with subjective well-being. Studies on well-being can also make a great contribution in the investigation of the causes of the knowledge-concern-action paradox. All these considerations are of great importance for the design and implementation of public policies aimed at putting an end to environmental degradation, as well as to foster a growing consciousness among population on the need for a definitive solution to environmental problems.

    2014-01-01

    Background Frankincense (Boswellia carterii, known as Ru Xiang in Chinese) and sandalwood (Santalum album, known as Tan Xiang in Chinese) are cancer preventive and therapeutic agents in Chinese medicine. Their biologically active ingredients are usually extracted from frankincense by hydrodistillation and sandalwood by distillation. This study aims to investigate the anti-proliferative and pro-apoptotic activities of frankincense and sandalwood essential oils in cultured human bladder cancer cells. Methods The effects of frankincense (1,400–600 dilutions) (v/v) and sandalwood (16,000–7,000 dilutions) (v/v) essential oils on cell viability were studied in established human bladder cancer J82 cells and immortalized normal human bladder urothelial UROtsa cells using a colorimetric XTT cell viability assay. Genes that responded to essential oil treatments in human bladder cancer J82 cells were identified using the Illumina Expression BeadChip platform and analyzed for enriched functions and pathways. The chemical compositions of the essential oils were determined by gas chromatography–mass spectrometry. Results Human bladder cancer J82 cells were more sensitive to the pro-apoptotic effects of frankincense essential oil than the immortalized normal bladder UROtsa cells. In contrast, sandalwood essential oil exhibited a similar potency in suppressing the viability of both J82 and UROtsa cells. Although frankincense and sandalwood essential oils activated common pathways such as inflammatory interleukins (IL-6 signaling), each essential oil had a unique molecular action on the bladder cancer cells. Heat shock proteins and histone core proteins were activated by frankincense essential oil, whereas negative regulation of protein kinase activity and G protein-coupled receptors were activated by sandalwood essential oil treatment. Conclusion The effects of frankincense and sandalwood essential oils on J82 cells and UROtsa cells involved different mechanisms leading to

  7. Combined Usage of TanDEM-X and CryoSat-2 for Generating a High Resolution Digital Elevation Model of Fast Moving Ice Stream and Its Application in Grounding Line Estimation

    Full Text Available Definite surface topography of ice provides fundamental information for most glaciologists to study climate change. However, the topography at the marginal region of ice sheets exhibits noticeable dynamical changes from fast flow velocity and large thinning rates; thus, it is difficult to determine instantaneous topography. In this study, the surface topography of the marginal region of Thwaites Glacier in the Amundsen Sector of West Antarctica, where ice melting and thinning are prevailing, is extracted using TanDEM-X interferometry in combination with data from the near-coincident CryoSat-2 radar altimeter. The absolute height offset, which has been a persistent problem in applying the interferometry technique for generating DEMs, is determined by linear least-squares fitting between the uncorrected TanDEM-X heights and reliable reference heights from CryoSat-2. The reliable heights are rigorously selected at locations of high normalized cross-correlation and low RMS heights between segments of data points. The generated digital elevation model with the resolved absolute height offset is assessed with airborne laser altimeter data from the Operation IceBridge that were acquired five months after TanDEM-X and show high correlation with biases of 3.19 m and −4.31 m at the grounding zone and over the ice sheet surface, respectively. For practical application of the generated DEM, grounding line estimation assuming hydrostatic equilibrium was carried out, and the feasibility was seen through comparison with the previous grounding line. Finally, it is expected that the combination of interferometry and altimetery with similar datasets can be applied at regions even with a lack of ground control points.

    Characterization of lava flow after its emplacement provides volume and constraints for lava flow emplacement simulations that help assess pending volcanic hazards. Additionally, it gives us better insights in understanding the dynamics of the underlying magmatic plumbing system and the possible mechanism of the eruption. In this work, we developed a technique using monostatic Cosmo-SkyMed and bistatic TanDEM-X data to calculate the volume, measure the thickness, and the horizontal and vertical displacements immediately after the emplacement of the October 2010 lava flow at Piton de la Fournaise. Results show that the thickest part of the October 2010 lava flow is about 13 to 16 m and the DRE volume is estimated to fall within the range of 1.71 to 3.00 x 106 m3 (±1σ), depending on which InSAR database was used. We also observe that the October 2010 lava flow is subsiding at a maximum rate of 14 cm yr-1. Apart from the vertical displacement, joint sliding and centripetal displacement were also identified with a maximum rate of 4.0 cm yr-1. We cross-validated our InSAR results with the mixed-pixel technique of Harris [1997] in terms of the estimated volumes. Our analysis shows that the volume derived using a few TanDEM-X interferograms fitted well within the range of volume given by the mixed-pixel technique as compared to the huge monostatic Cosmo-SkyMed database. In addition to the October 2010 lava flow, we also characterized the thin lava flow deposit of the December 2010 eruption, however using only bistatic TanDEM-X data. In this case of thin lava deposits, we expect that TanDEM-X are best to use in deriving the thickness and estimating the volume as these type of data are more sensitive to topographic change.

    Full Text Available Adipose tissue is a reservoir of energy and also an organ that contributes to the aesthetics and health of human body working as an endocrine tissue. White adipose tissue, which is formed by unilocular adipose cells, can modify organic homeostasis by controlling energy expenditure and consumption and by producing adipokines that regulate food consumption, and carbohydrate and lipid metabolic utilization. Brown adipose tissue is structured by multilocular cells containing many small fat drops that can be easily hydrolyzed. This tissue is involved in adaptative or facultative thermogenesis because it contains the uncoupling-1 protein (UCP-1 which by inhibiting ATP synthesis releases heat. The size of brow adipose tissue is reduced with aging and the most recent future strategies to fight obesity may be by transforming white cells into brown adipose tissue. The present work reviews the main structural and functional characteristics of white and brown adipose tissue with emphasis in its endocrine and regulatory function.El tejido adiposo es un reservorio de grasa y también un órgano que contribuye a la estética y a la salud de las personas, tarea que cumple funcionando como un tejido endocrino. El tejido adiposo blanco, formado por células adiposas uniloculares puede regular la homeostasis orgánica entre el gasto y el consumo de energía. Produce una serie de adipokinas que regulan el consumo de alimentos, la utilización de glucosa y de lípidos por parte del organismo. El tejido adiposo pardo o marrón, estructurado por células multiloculares, contiene numerosas gotas de grasa de pequeño tamaño, las que pueden ser hidrolizadas con mayor facilidad. El tejido participa en la termogénesis adaptativa o facultativa debido a la proteína desacoplante-1 (UCP-1 que inhibe la síntesis de ATP produciendo calor. Con la edad, este tejido se reduce y por ello actualmente se considera que una forma de combatir la obesidad es lograr que el tejido adiposo blanco adquiera característica de pardo. Este trabajo revisa las principales características estructurales y funcionales del tejido adiposo blanco y pardo, con énfasis en sus funciones reguladoras y endocrinas.

    Full Text Available Sport practices belong to the prison’s landscape. Nevertheless, there is a lack of knowledge about the role they play in prisons ordinary life. Therefore, we developed an ethnographic study, mainly located in the sports hall of a Spanish prison, to understand exercise and sport meanings among inmates, workers, educators and monitors. Data indicate that social rehabilitation through sport is an illusion, although it is the official goal of imprisonment. Even so, participants assign different benefits to exercise and sport, especially inmates. Educative potential of self-control through sport and, mainly, distraction and compensation strategy to cope with boredom, time and confinement’s physical and mental problems are among them. Paper concludes that exercise and sport can play a symbolic ‘evasion’ and personal liberation, but are constrained by a context in which control and order are at the forefront of everything.

    Las actividades deportivas forman parte del paisaje de las prisiones. Sin embargo, escasea el conocimiento sobre el papel que desempeñan en la vida cotidiana de las cárceles. Por ello realizamos un estudio etnográfico, principalmente en el polideportivo de una prisión española, dirigido a comprender los significados que el ejercicio físico y el deporte tenían para los presos, funcionarios, educadores y monitores. Los resultados indican que la reinserción mediante estas prácticas es una ilusión, a pesar de ser la finalidad oficial de la reclusión. Aun así, les asignan diversos beneficios, especialmente los presos y presas. Entre ellos se encuentra el potencial educativo ligado al autocontrol y, sobre todo, el entretenimiento y la compensación para ocupar el tiempo, huir del hastío y sobrellevar los problemas del encierro. El artículo concluye que el ejercicio y el deporte pueden tener un papel de “evasión” simbólica y liberación personal, aunque los presos viven atenazados por un contexto en el que prima el orden y el control por encima de todo.

    Full Text Available RESUMEN: La autoestima es uno de los conceptos psicológicos más complejos y uno de los más difíciles de precisar, a pesar de ser un factor que siempre ha estado presente en cualquier intento de explicación del comportamiento humano normal y patológico. Describir adecuadamente qué es la autoestima, requiere abordar previamente algunos aspectos que han influido en la falta de precisión de este concepto. En este sentido es necesario puntualizar que autoconcepto y autoestima no son términos intercambiables aunque ambos se impliquen, que la autoestima no es un factor unitario sino multidimensional, que la autoestima no sólo incluye los aspectos positivos y más valorables del sujeto, sino también aspectos menos valorables o las limitaciones y por último, que la autoestima no es autoafirmación incondicional ante los demás, sino autoafirmación respetando la individualidad de los otros. Se puede definir la autoestima como «la valoración positiva o negativa que el sujeto hace de su autoconcepto, valoración que se acompaña de sentimientos de valía personal y auto aceptación». La autoestima, así entendida, influye y se expresa a través del comportamiento del sujeto en todas sus dimensiones y manifestaciones, tales como autoaceptación, afrontamiento, aceptación de los demás e interacciones sociales, entre otras.ABSTRACT: Self-esteem is one of the most complex psychological concepts an one of the most difficult ones to define, despite the fact that it is a factor that has always been present in any attempt to explain the normal and pathological human behavior. In order to describe adequately what self-esteem is we need to first look at some of the aspects that have contributed to the lack of precision of this concept. We need to make clear that self-concept and self-esteem are not interchangeable terms even though they are both in some way related, that self-esteem not a unitary factor but multidimensional, that self-esteem not only includes the most positive and valued aspects and limitations of the individual but it also includes less valued aspects and limitations of the individual and that, finally, self-esteem is not an unconditional self-assertiveness in de eyes of others but self-assertiveness respecting the individuality of others. You can define sel-esteem like the «positive or negative valuation that the individual makes of this self-concept. Such valuation goes together with feelings of self-acceptance and value». Self-esteem understood as described above influences and is expresed through the behavior of the individual in all her dimensions and manifestations such as self-acceptance, acceptance of others and interactions with others.

    Posteriormente estudió derecho en la Universidad Nacional y se graduó de abogado en 1917. En 1921 publicó "Tierra de Promisión", su admirable libro de sonetos y al año siguiente fue designado Secretario
    de la Comisión de Limites con Venezuela; en 1924 publicó La Vorágine y en 1928 fue nombrado delegado de la Conferencia Internacional de Emigración de la Habana. Se trasladó enseguida a Nueva York en donde transcurrieron los últimos meses de su vida, habiendo fallecido el 1 de diciembre de 1928, a las 12:50, a los 40 años y 9 meses de su edad.

    Rivera, por su profesión de abogado, atendía cuantiosos pleitos en los Llanos de Casanare, por lo cual permanecía largas temporadas en Sogamaso, puerta de entrada a Los Llanos, alojándose en la pensión de doña Adriana Camargo de Albarracín o en la quinta de su amigo Lisandro Durán que quedaba en las estribaciones que cierran el valle hacia el noroeste.

    Full Text Available La comprensión lectora es uno de los principales temas de estudioen el ámbito educativo, tanto por la complejidad de los procesos yhabilidades implicados como por la importancia que tiene en la adquisición de contenidos escolares. El déficit en la lectura comprensiva es consecuencia de varios factores entre los que seencuentra la pobreza de vocabulario. Con nuestra investigación tratamos de determinar en qué medida existen dificultades en la comprensión lectora en escolares de educación primaria y si existen limitaciones en el vocabulario de los niños que la presentan.

    La diabetes (DM) en embarazo es pregestacional (DPG), incluye a la diagnosticada en primer trimestre y gestacional (DG). La prevalencia DM creciente de obesidad y DM2 y embarazos tardíos, han aumentado la DG y DPG tipo 2. Persiste controversia en diagnóstico de DG. Las metas glucídicas son más estrictas en la gestación. Tratamiento en DPG: Programación del embarazo, buen control glicémico y complicaciones de su DM ausentes o tratadas. La DM1 intensifica la insulinoterapia y la DM2 la inici...

    DG: Cambios de estilo de vida; monitoreo de glucosa capilar e insulina si no se alcanzan metas. La terapia es beneficiosa para madre e hijo. El uso de antidiabéticos orales es controvertido. La glibenclamida estaría contraindicada: más macrosomía e hipoglicemia neonatal. La metformina presenta ciertas ventajas inmediatas, pero más parto pretérmino y sin estudios de seguridad a mayores plazos. El trabajo en equipo, educación y prevención de DM en DG son claves.

    Full Text Available The Western Culture, which entered every phase of the Ottoman life after the Reform, also brought the question of the place of women in a society. Woman is seen as one of the most significant phases of modernization by the Reform Intellectuals. The idea that a new and modern society can only be formed by new and modern mothers had been a common thesis of the literary works until the proclamation of the Republic. In this stage, the female novelists, whose number was increasing, in their works dealt with the issues of modernizing women in detail. The modernization of women, and thus the stages that a society has while having process of westernization is traced through the women characters in women novels. In this work, we will analyze women modernization through characters and contexts in the novels written by female writers during the process reaching from the Reforms to the Republic. Tanzimat’tan sonra Osmanlı hayatının her safhasına giren Batı kültürü, toplum içerisinde kadının yerinin sorgulanmasını da beraberinde getirir. Kadın, Tanzimat aydını tarafından modernleşmenin en önemli aşamalarından biri olarak görülür. Yeni ve modern toplumun ancak yeni ve modern anneler tarafından kurulabileceği fikri, Cumhuriyet’in ilanına kadar edebi eserlerin ortak tezlerinden biri hâline gelir. Bu safhada sayısı artan kadın romancılar, modernleşen kadının meselelerini teferruatlı bir şekilde ele alırlar. Kadının modernleşmesi, dolayısıyla toplumun Batılılaşırken geçirdiği safhalar, kadın romanlarındaki kadın kahramanlar üzerinden takip edilebilir. Biz bu çalışmamızda Tanzimat’tan Cumhuriyet’e uzanan süreçte kadın yazarlar tarafından kaleme alınan romanlarda, kadın modernleşmesinin hangi karakterler üzerinden ve hangi meseleler bağlamında ele alındığını inceleyeceğiz.

    Full Text Available Tourism and religion have been in co-operation with each other due to the"Hajj pilgrimage" throughout history. The concept of religious tourism of today is based on this co-operation. All sectors of tourism, including religious tourism, need publicity first and then to market their destinations and the travel programs for survival. The emerging "social media networks " that appeared after the developments in Internet technology are thought to be useful tools in both fields. Scientific researches have discovered a strong relationship between the use of social media and consumers' purchasing decisions or renunciation. This relationship can be used as an efficient support in promoting and marketing of destinations and tour programs in religious tourism industry. According to reseachers, people, who share their past travel experiences with friends and relatives on the social media, can be effective on the travel plans of others, from choosing destinations to hotels and restaurants. Social media is seen as a great tool of promotion and marketing for all kinds of businesses but like any other tools, social media have useful and harmful aspects. If they are used cleverly, social media can carry businesses to distant horizons beyond their imaginations but improper use of social media can do more harm than good. There is no study which examines the role of social media in promoting and development of religious tourism. The purpose of this study is to research the importance of the role that social media can play in the development and promotion of religious tourism and produce solutions to probable problems that may arise.

    The Tan-Lu fault (TLF) is a significant linear structure of eastern China. The middle segment of the TLF in the northern Anhui Province separates the North China Block (NCB) and South China Block (SCB). Lack of geological work makes the plate boundary here ambiguous. Detailed field survey and laboratory analyses have been conducted to constrain the formation and evolution of the TLF. To the west of the TLF, the Wuhe massif underwent a granulite facies metamorphism with T = 778-836 °C, P = 1.0-1.2 GPa during 2.41-2.43 Ga according to LA-ICP-MS U-Pb zircon dating. On the contrary, to the east of the TLF, the Zhangbaling massif suffered a greenschist to lower amphibolite facies metamorphism with the average metamorphic temperature at around 340-440 °C, with the protolith igneous ages of ca. 750 Ma. These differences indicate that the two massifs belong to the different blocks. Furthermore, the granitic gneiss in the central part of TLF gives three populations of zircon U-Pb age at 667-504 Ma, 228 ± 2 Ma and 211 ± 2 Ma, respectively. The later two groups of spectra correspond to the periods of subduction and exhumation of the Dabie massif (245-200 Ma). Combined with previous study, the precise plate boundary between NCB and SCB has been delineated as the Zhuding-Shimenshan fault, and the initial time of the motion for the TLF is also discussed.

    Vegetated coastal ecosystems, also called Blue Carbon ecosystems are highly efficient carbon sinks and have been shown to play a role in ameliorating the effect of increasing global climate change by capturing significant amounts of carbon into sediments and plant biomass. Mangrove-lined estuaries and coastal ecosystems are significant to global biogeochemical processes and regulate the structure, productivity and function of adjacent coastal ecosystems disproportionately to their land cover. Here we present recent efforts by the CMS Total Blue Carbon Stocks in Africa Project to estimate total (above and belowground) carbon stocks in East and Central Africa using in situ, high resolution stereo, airborne lidar and spaceborne SAR data. We generated Mangrove extent and change maps and canopy height estimates for the 2000 and 2015 eras that were used as input to carry out stratified field plot samples of above, below and soil Carbon stocks in the Rufiji Delta, Tanzania, Zambezi Delta, Mozambique and Pongara National Park, Gabon. By combining the field measurements and remotely sensed data, we estimated countrywide mangrove total carbon stocks. Uncertainties of estimates associated with different remote sensing input data were also calculated and will be presented. In this talk, we will give an overview of recent efforts to quantify mangrove forest 3-D structure, composition and change at high resolution globally in the context of estimating forest biomass and blue carbon stocks. Our presentation covers field and remotely sensed investigations and describes unique remotely sensed datasets produced and collected at NASA, with an emphasis on recently collected airborne Lidar and Radar from the AfriSAR campaign. Specifically, we will present new results focusing on the validation and comparison of independent mangrove canopy height and biomass measurements from commercial airborne lidar, LVIS, TanDEM-X, UAVSAR and World View, from Gabon, Mozambique and Tanzania.

    A Gram-staining-negative, non-pigmented, strictly aerobic, rod-shaped, non-spore-forming, non-motile bacterium, devoid of bacteriochlorophyll, designated strain CC-AMW-E(T), was isolated from surface seawater off the coast at Kending, Taiwan. Strain CC-AMW-E(T) shared 95.7 and 93.9% 16S rRNA gene sequence similarity, respectively, with the type strains of the type species of the genera Donghicola (Donghicola eburneus SW-277(T)) and Roseovarius (Roseovarius tolerans EL-172(T)). The predominant (>75% of the total) fatty acid was summed feature 8 (C(18 : 1)ω6c and/or C(18 : 1)ω7c). The polar lipid profile included major amounts of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine and an unidentified aminolipid. In addition, moderate amounts of an unidentified lipid and trace amounts of an unidentified phospholipid were detected. The DNA G+C content was 67.9 mol%. Ubiquinone Q-10 was the sole respiratory quinone. Based on its phylogenetic distinctiveness and distinguishing phenotypic characteristics (in particular its polar lipid pattern), we conclude that strain CC-AMW-E(T) represents a novel genus and species of the family Rhodobacteraceae, for which the name Youngimonas vesicularis gen. nov., sp. nov. is proposed. The type strain of Youngimonas vesicularis is CC-AMW-E(T) ( = JCM 18819(T) = BCRC 80549(T)). In addition, an emended description of the genus Donghicola Yoon et al. 2007 and the reclassification of Donghicola xiamenensis Tan et al. 2009 as Pseudodonghicola xiamenensis gen. nov., comb. nov. (type strain Y-2(T) = MCCC 1A00107(T) = LMG 24574(T) = CGMCC 1.7081(T)) are proposed. © 2014 IUMS.
