    2016-01-01

    Existen numerosas ventajas asociada con el uso de CO2 , tanto como disolvente que como reactivo, y todas se pueden resumir en cuatro categorías generales: beneficios ambiental, beneficios de salud y seguridad, beneficios en el procedimiento y beneficios químicos. Los procesos que implican el CO2 como disolvente no aumentaría las emisiones de CO2, más bien proporcionaría una oportunidad para el reciclaje de CO2 residual. Además, los esfuerzos para secuestrar el CO2 producido de los gases de co...

  6. NUEVOS ANTICOAGULANTES ORALES EN FIBRILACIÓN AURICULAR

    Directory of Open Access Journals (Sweden)

    2015-03-01

    Full Text Available La fibrilación auricular es la arritmia más frecuente y se relaciona con una alta tasa de accidente cerebrovascular y embolia sistécmica. La terapia establecida tanto para prevención primaria como secundaria es la anticoagulación con warfarina, antagonista de la vitamina K. Existen escalas que predicen el riesgo tromboembólico y la probabilidad de beneficiarse de terapia antitrombótica. El CHADS2 ha sido la más simple y ampliamente utilizada, pero actualmente el CHA2DS2-VASc ha incorporado otros factores de riesgo, otorgando una mejor estratificación. El estrecho margen terapécutico de la warfarina y la interacción con fármacos y alimentos requiere controles seriados de la intensidad de la anticoagulación, limitando su uso clínico. Han aparecido nuevos anticoagulantes que ofrecen ventajas sobre los antagonistas de vitamina K. Estos actúan en dos sitios distintos de la cascada de la coagulación: inhibiendo directamente la trombina como el dabigatran, o el factor X activado como el rivaroxaban, apixaban, edoxaban y betrixaban. Estos nuevos fármacos han ido reemplazando a la warfarina y ya están incluidos en las guías de manejo de fibrilación auricular no valvular.

    2011-06-01

    Full Text Available La fibrilación auricular es la taquiarritmia cardíaca más frecuente. Su incidencia aumenta con la edad, presentándose en un 1.5% entre los 50 a 59 años, y en un 8-10% entre los 80 a 89 años. Esta arritmia incrementa en cinco veces el riesgo de sufrir un evento cerebrovascular isquémico cardioembólico y causa el 15% de todos los accidentes cerebrovasculares isquémicos. Su manejo se enfoca en la prevención de los fenómenos tromboembólicos y el control de la frecuencia y ritmo cardíaco. El tratamiento anticoagulante ha demostrado ser la principal herramienta en la prevención de eventos cardioembólicos. Aunque las complicaciones hemorrágicas por el tratamiento son esperables y aumentan con la edad, el beneficio de usar anticoagulación sobrepasa por mucho al riesgo de sangrado. Precisamente debido a la heterogeneidad clínica de esta arritmia y a la dificultad de establecer un tratamiento adecuado para cada caso en particular, el American College of Cardiology, la American Heart Association, la European Society of Cardiology y el American College of Chest Physicians han establecido guías para mejorar el tratamiento de estos pacientes. La revisión de esta enfermedad y de las directrices propuestas puede facilitar y mejorar notablemente el tratamiento de los pacientes con fibrilación auricular.

    Rubén Guillermo Jaramillo Salamanca

    2016-04-01

    Full Text Available Los anticoagulantes orales directos surgieron en respuesta a la búsqueda de un anticoagulante ideal después de que la warfarina fuera por mucho tiempo el único disponible. Los inhibidores del factor X activado —rivaroxabán y apixabán— y el inhibidor de trombina —dabigatrán etexilato— ya están aprobados en Colombia. Estos grupos farmacológicos están indicados en la tromboprofilaxis luego de artroplastia de rodilla y cadera, en la prevención del accidente cerebrovascular y el embolismo sistémico en pacientes con fibrilación auricular no valvular y en el tratamiento del tromboembolismo venoso. La aprobación de los inhibidores se dio luego de mostrar eficacia y seguridad al compararse con warfarina y enoxaparina. Entre las ventajas que estos presentan figuran las siguientes: inicio rápido de acción, efecto predecible, poca variabilidad interindividual que elimina la necesidad de la monitorización frecuente y menos interacciones medicamentosas; pero, al igual que en la warfarina, el sangrado es el principal evento adverso.   El objetivo de esta revisión es conocer la farmacología de los anticoagulantes orales directos aprobados en Colombia, los resultados de los ensayos clínicos que respaldan su uso, la dosificación, el uso perioperatorio y el cambio entre anticoagulantes; situaciones que plantean particularidades para cada uno.

    2015-12-15

    AIN/Cu composite powders with a core-shell structure were synthesized by a new technique using electroless plating of Cu on AIN particles and consolidated by spark plasma sintering (SPS). Dependence of the thermal conductivity and coefficient of thermal expansion (CTE) of the AIN/Cu composites on the particle size of AIN were studied. The thermal conductivity and coefficient of thermal expansion were significantly dependent on the existence of both boundary pores surrounding the Cu-coated AIN particles and the internal pores of the AIN particles. In order to eliminate the pores, the temperature and pressure of SPS were increased and the AIN particles were heat-treated at high temperature. Adoption of the core-shell AIN/Cu composite powders facilitated the fabrications of AIN/Cu composites with low porosity and uniform distribution in the AIN in Cu matrix.

    Full Text Available El dabigatrán es un nuevo inhibidor directo de la trombina, de administración oral, empleado para la prevención de eventos tromboembólicos en pacientes con fibrilación auricular no valvular. A diferencia de la warfarina, no se dispone de un antídoto conocido. La hemodiálisis ha sido sugerida como un método para remover el dabigatrán y reducir el efecto anticoagulante. Se presenta el caso de un paciente con antecedente de fibrilación auricular y medicado con dabigatrán, que fue admitido en el hospital para una cirugía abdominal de urgencia. A las seis horas de la última dosis recibida, los estudios de coagulación mostraban alteración. Ante la falta de antídoto para revertir los efectos, se decidió realizar hemodiálisis. Luego de tres horas de diálisis los parámetros de coagulación tendieron a normalizarse y el paciente fue operado sin presentar hemorragias anormales durante la cirugía o en el postoperatorio.

    Full Text Available Chromium and its compounds give toxic and/or hazardous characteristics to all those industrial wastes, solids or liquids, that contain them. Organic solvent extraction is a technique that allows the recovery of chromium contained in these residues. In this work the extraction of Cr(III from aqueous solutions with solutions of a cationic reactive (DEHPA in kerosene is studied. In the same way the stripping process was studied. It has been found that Cr(III and DEHPA react in a 1/1 molar ratio, being the extraction kinetics very fast. Final aqueous phase final pH influence extraction yield, so that it is necessary to work with pH values between 3 and 4. It must be added a modifier (isodecanol to the organic phase to avoid the formation of a third phase in the stripping process. The concentration of isodecanol has to be higher than 15 %, so the organic phase used was a solution of 12.5 % v/v DEHPA in kerosene and 20 % v/v isodecanol. The stripping process is slow and must be carried out in an oxidant alkalyne medium, thus an aqueous solution of NaOH and H2O2 was used. An increase in the concentration of NaOH and H2O2 leads to an increase in the stripping yield initially, and becomes stable when concentrations of NaOH and H2O2 used are higher than 0.45 N and 4 % v/v respectively.

    We have calculated the electronic structure and optical properties of Wurtzite structure AIN under different high pressure with generalized gradient approximation (GGA) in this paper. The total energy, density of state, energy band structure and optical absorption and reflection properties under high pressure are calculated. By comparing the changes of the energy band structure, we obtained AIN phase transition pressure for 16.7 GPa, which is a direct band structure transforming to an indirect band structure. Meanwhile, according to the density of states distribution and energy band structure, we analyzed the optical properties of AIN under high-pressure, the results showed that the absorption spectra moved from low-energy to high-energy.

Se apresenta sob as formas de filoquinona (K1-predominante, dihidrofiloquinona (dK, menaquinona (K2 e menadiona (K3. Os fatores que interferem em sua absorção são: má absorção gastrintestinal, secreção biliar, ingestão insuficiente e uso de anticoagulantes, entre outros. As principais fontes de vitamina K são os vegetais e óleos, sendo esses os responsáveis pelo aumento da absorção da filoquinona. Os alimentos folhosos verde escuro, os preparados à base de óleo, oleaginosas e frutas como o kiwi, abacate, uva, ameixa e figo contêm teores significantes de vitamina K, enquanto que os cereais, grãos, pães e laticínios possuem teores discretos. A ingestão diária de aproximadamente 1µg por quilo de peso é considerada a mais segura, inclusive para a utilização de anticoagulantes orais, em que a concentração estável da vitamina proporciona a eficácia no tratamento. A droga anticoagulante oral geralmente utilizada é a varfarina, administrada como profilática e para tratamento de fenômenos tromboembólicos. Essa intervenção medicamentosa é monitorada pelo tempo de protrombina expresso pela razão normalizada internacional, tendo como objetivo estabelecer a faixa terapêutica entre 2 e 3, minimizando o risco de hemorragias. O efeito anticoagulante pode ser reduzido por fatores como ganho de peso, diarréia, vômito, idade menor que 40 anos e consumo excessivo de vitamina K na dieta alimentar.Vitamin K is a fat-soluble substance, mainly involved in the blood coagulation. It is presented as Phylloquinone (K1-predominant, Dihydrophyloquinone (dK, Menaquinone (K2, and Menadione (K3. The factors that interfere with its absorption are: gastrointestinal malabsorption, biliary secretion, inadequate ingestion and anticoagulant use, among others. The main vitamin K sources are vegetables and organic lipids, that are involved in the increased absorption of

    2011-10-01

    In this paper, we reported the oxidation behaviour of Ti2AIN films on polycrystalline Al2O3 substrates. The Ti2AIN films composed mainly of nanolaminated MAX phase was obtained by first depositing Ti-Al-N films using reactive sputtering of two elemental Ti and Al targets in Ar/N2 atmosphere and subsequent vacuum annealing at 800 degrees C for 1 h. The Ti2AIN films exhibited excellent oxidation resistance and thermal stability at 600-900 degrees C in air. Very low mass gain was observed. At low temperature (600 degrees C), no oxide crystals were observed on film surface. Blade-like Theta-Al2O3 fine crystals formed on film surfaces at 700-800 degrees C. At high temperature (900 degrees C), firstly Theta-Al2O3 formed on film surface and then transformed into alpha-Al2O3. At 700-900 degrees C, a continuous Al2O3 layer formed on Ti2AIN films surface, acting as diffusion barrier preventing further oxidation attack. The mechanism of the excellent oxidation resistance of Ti2AIN films was discussed based on the experimental results.

    2004-01-01

    The properties of leaky surface acoustic waves (LSAW) in MBE grown AIN layer on Z-cut LiNbO 3 structures have been studied by numerical simulation and experimental measurements and compared with those of Rayleigh waves in the same structure. In the range of AIN layer thicknesses studied (0 3 substrate was essentially constant at around 4400 m/s. The measured electromechanical coupling coefficients (K 2 ) for the LSAW are roughly 1/4 of the predicted values, which might be due to the strong attenuation of the leaky wave unaccounted for during the parameter extraction. The thin AIN film slightly improved the measured temperature coefficient of frequency for the LSAW over that attained for the Z-cut, X-propagating LiNbO 3 substrate alone

    Full Text Available Abstract Background Human papillomavirus (HPV is well known as the major etiological agent for ano-genital cancer. In contrast to cervical cancer, anal cancer is uncommon, but is increasing steadily in the community over the last few decades. However, it has undergone an exponential rise in the men who have sex with men (MSM and HIV + groups. HIV + MSM in particular, have anal cancer incidences about three times that of the highest worldwide reported cervical cancer incidences. Discussion There has therefore traditionally been a lack of data from studies focused on heterosexual men and non-HIV + women. There is also less evidence reporting on the putative precursor lesion to anal cancer (AIN – anal intraepithelial neoplasia, when compared to cervical cancer and CIN (cervical intraepithelial neoplasia. This review summarises the available biological and epidemiological evidence for HPV in the anal site and the pathogenesis of AIN and anal cancer amongst traditionally non-high risk groups. Summary There is strong evidence to conclude that high-grade AIN is a precursor to anal cancer, and some data on the progression of AIN to invasive cancer.

  4. Fabrication and performance of AIN insulator coatings for application in fusion reactor blankets

    Natesan, K.

    1995-09-01

    The liquid-metal blanket concept for fusion reactors requires an coating on the first-wall structural material to minimize the magnetohydrodynamic pressure drop that occurs during the flow of liquid metal in a magnetic field. Based on the thermodynamics of interactions betwen the coating and the liquid lithium on one side and the structural V-base alloy on the other side, an AIN coating was selected as a candidate. Detailed investigations were conducted on the fabrication, metallurgical microstructure, compatibility in liquid Li, and electrical characteristics of AIN material obtained from several sources. Lithium compatibility was studied in static systems by exposing AIN-coated specimens to liquid Li for several time periods. Electrical resistance was measured at room temperature on the specimens before and after exposure to liquid Li. The results obtained in this study indicate that AIN is a viable coating from the standpoint of chemical compatibility in Li, electrical insulation, and ease of fabrication; for these reasons, the coating should be examined further for fusion reactor applications

    Full Text Available Após cerca de 50 anos de experiência com a heparina e antagonistas da vitamina K (AVK, pesquisas e estudos com novos anticoagulantes vêm evoluindo de forma crescente nos últimos anos. Embora consagrados pelo uso, os anticoagulantes tradicionais têm limitações importantes em termos de controle laboratorial, complicações, efeitos colaterais, interações com medicamentos e dieta. A heparina não fracionada (HNF tem interação com proteínas plasmáticas e parede vascular, pode desencadear trombocitopenia induzida pela heparina (TIH, só pode ser administrada por via parenteral, exige controle laboratorial pelo teste da tromboplastina parcial ativada (TTPa, pode provocar osteoporose e alopecia quando usada por períodos prolongados e sua produção tem origem biológica. A AVK tem a vantagem de poder ser ministrada por via oral, mas o controle (feito pela razão normatizada internacional pode ser difícil em alguns casos, já que tem início de ação demorado, janela terapêutica estreita, interação com dieta e grande número de medicamentos, pode provocar necrose de pele em portadores de deficiência de antitrombina e de proteínas C e S, e pode induzir alterações fetais quando usada na gravidez. Na década de 1980, surgiram as heparinas de baixo peso molecular, que foram uma evolução da heparina não fracionada, pois apresentaram maior biodisponibilidade, dosagem por peso corporal, sem necessidade de controle laboratorial, administração por via subcutânea, menor risco de trombocitopenia induzida pela heparina, e eficácia e segurança similares à heparina não fracionada. Na última década surgiram, então, uma série de novos anticoagulantes no mercado, os quais têm apresentado resultados promissores em várias situações de profilaxia e tratamento do tromboembolismo venoso. Nesta revisão, são apresentados as novas heparinas de baixo peso molecular, as heparinas de ultrabaixo peso molecular, os pentassacarídeos, os

    Full Text Available La fibrilación auricular es el trastorno más frecuente del ritmo cardíaco y una de las causas potencialmente tratables de cardioembolia y ataque cerebrovascular. La disponibilidad de nuevos anticoagulantes para pacientes con fibrilación auricular no valvular, plantea retos, derivados principalmente de los costos de su uso, perfiles de eficacia y seguridad, tolerancia y disponibilidad. Se llevó a cabo un análisis de costo-efectividad con base en un modelo de Markov, que permite comparar las estrategias de anticoagulación disponibles para fibrilación auricular no valvular en el país (apixabán, dabigatrán, rivaroxabán. La perspectiva empleada fue la del tercero pagador (sistema de salud colombiano, considerando solo costos médicos directos. Se siguieron las guías metodológicas para este tipo de estudios propuestas por ISPOR (International Society for Pharmacoeconomics and Outcomes Research e INAHTA (International Network of Agencies for Health Technology Assessment. El horizonte temporal fue de 5 años, 10 años y toda la vida, en tanto que la tasa de descuento fue del 3%. Luego de la evaluación del modelo, con base en los análisis de sensibilidad realizados y el umbral de costo-efectividad para Colombia, se encontró que para el caso base, las diferentes moléculas evaluadas, si bien son costo-efectivas, exceden el umbral propuesto para este trabajo, siendo rivaroxabán y dabigatrán las únicas estrategias costo-efectivas con un horizonte temporal a 10 años con una tasa de descuento del 3% y para un horizonte temporal de toda la vida y tasa de descuento del 3%, las tres moléculas alcanzan el umbral de costo-efectividad establecido para Colombia. Dichas consideraciones son altamente sensibles al costo de los medicamentos.

    There are several standard diets for animals used in scientific research, usually conceived by scientific institutions. The AIN-93 diet is widely used, but there are some reports of fatty liver in Wistar rats fed this diet. We aimed to evaluate the hepatic repercussions of the AIN-93 diet intake in Wistar rats. Forty newly-weaned 21-day-old male Wistar rats were fed either the AIN-93 diet or a commercial diet for either 1 month or 4 months. Weight gain, serum biochemistry, hepatic histology, and hepatic fatty acid profile were analyzed. Hepatic steatosis was observed, especially in the group fed the AIN-93 diet. Serum blood glucose, absolute and relative liver weight and hepatic levels of oleic, palmitoleic, stearic, and palmitic fatty acids were related to the observed steatosis, while lipidogram and serum markers of liver function and injury were not. AIN-93 diet induced acute hepatic steatosis in Wistar rats, which may compromise its use as a standard diet for experimental studies with rodents. The hepatic fatty acid profile was associated with steatosis, with possible implications for disease prognosis. Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA. All rights reserved.

    The urban growth of AL Ain city has been investigated using remote sensing data for three different dates, 1972, 1990 and 2000. We used three Landsat images together with socio-economic data in a post-classification analysis to map the spatial dynamics of land use/cover changes and identify the urbanization process in Al Ain resort city, United Arab Emirates. Land use/cover statistics, extracted from Landsat Multi-spectral Scanner (MSS). Thematic Mapper (TM) and Enhanced Thematic Mapper plus (ETM +) images for 1972. 1990 and 2000 respectively, revealed that the built-up area has expanded by about 170.53km2. The city was found to have a tendency for major expansion in four different directions: along the Abu Dhabi highway, along Dubai highway, Myziad direction and Hafeet recreational area. Expansion in any direction was found to be governed by the availability of road network, suitability for construction, utilities, economic activities, geographical constraints, and legal factors (boundary with Sultanate of Oman). The road network in particular has influenced the spatial patterns and structure of urban development, so that the expansion of the built-up areas has assumed an accretive as well as linear growth along the major roads. The research concludes that the development is based on conservation of agricultural areas (oases) and reclamation of the desert for farming and agricultural activities. The integration of remote sensing and GIS was found to be effective in monitoring LULC changes and providing valuable information necessary for planning and research.

    The Honduras AIN-C programme is a preventive health and nutrition programme of the Honduras Ministry of Health (MOH) that relies on volunteers to help mothers monitor and maintain the adequate growth of young children. A quasi-experimental, design-based evaluation found that the programme achieved near-universal coverage and was effective in improving mothers' child-rearing knowledge, attitudes and practices, including feeding and appropriate care-giving and care-seeking practices for children with diarrhoea and acute respiratory illness. The programme is widely regarded as a model. This study was undertaken to provide the first comprehensive estimates of the cost of the AIN-C programme, with the goal of providing a programme and financial planning tool for Honduras. An additional comparison of study findings was also undertaken to determine the cost of the AIN-C programme's community-based services relative to a similar facility-based service. Expressed in mid-2005 US dollars, the study found that after the programme is phased-in: (1) the annual, recurrent cost per child under 2 years participating in the programme is $6.43; (2) the annual, incremental budget requirements per child under 2 years participating in the programme are $3.90; (3) the cost of an AIN-C monthly growth monitoring and counselling session per child is 11% of the cost of a traditional MOH, facility-based growth and development consultation per child; and (4) the effect of mothers substituting AIN-C monitor care for MOH facility-based care 'saves' 203 000 outpatient visits a year, with a potential cost saving of $1.66 million, the equivalent of 60% of the recurrent cost of the programme and roughly equal to the annual incremental budget requirements of the programme. Sensitivity analysis of the cost estimates is performed to provide insight, for countries considering introducing a similar programme, into how modifications of key characteristics of the programme affect its costs.

    Blooms of toxic cyanobacteria in Algerian reservoirs represent a potential health problem, mainly from drinking water that supplies the local population of Ain Zada (Bordj Bou Arreridj). The objective of this study is to monitor, detect, and identify the existence of cyanobacteria and microcystins during blooming times. Samples were taken in 2013 from eight stations. The results show that three potentially toxic cyanobacterial genera with the species Planktothrix agardhii were dominant. Cyanobacterial biomass, phycocyanin (PC) concentrations, and microcystin (MC) concentrations were high in the surface layer and at 14 m depth; these values were also high in the treated water. On 11 May 2013, MC concentrations were 6.3 μg/L in MC-LR equivalent in the drinking water. This study shows for the first time the presence of cyanotoxins in raw and treated waters, highlighting that regular monitoring of cyanobacteria and cyanotoxins must be undertaken to avoid potential health problems.

    Being seen needs in increasing waters in our contry for fine domestics, manufactures and agricultural, the prospecting of subterranean waters by geologic and hydrogeologic classic method remains inaplicable in the cases of the regions where one does not arrange drillings or polls (soundings) of gratitude (recongnition) in very sufficient (self-important) number. In that case of figure, the method of prospecting geophysics such as the method of nuclear magnetic resonance (NMR) and the method of the geophysics radar are usually used most usually because they showed, worldwide, results very desive in the projects of prospecting and evaluation of the resources in subterranean waters. In the present work, which concerns only the methodology of the electric resistivity, we treat the adopted methodological approach and the study of the case of application in the tray of Ajdir Ain Leuh.

    We present structure and spatially resolved composition studies by TEM (Transmission Electron Microscopy) and XANES (X-ray Absorption Near Edge Structure) of InAIN MOVPE (Metal-Organic Vapor Phase Epitaxy) epilayers containing 16-27 at% of indium. Investigations of the In L 3 edge by synchrotron radiation absorption show a significant change of the post-edge structure depending on the indium content. We attribute this to the solubility limit and phase separation in this system. Our measurements suggest that the critical composition is 18% for our growth conditions. HRTEM cross-sectional and EDX investigations confirm such phase separation as well as the changing of the structure from 2D growth to columnar like growth for the sample with the highest indium content.

    A significant number of patients return to optometric practice dissatisfied with their spectacles. An important question is whether any of these cases are preventable. There are several different clinical maxims that are used to modify the subjective refraction when determining the refractive prescription. These maxims aim to improve patient comfort and adaptation and thereby reduce patient dissatisfaction with new spectacles. They are not based on research evidence, but rather on expert opinion gained from clinical experience. The aim of this study was to retrospectively analyze a large number of case records of dissatisfied patients to assess the possible usefulness of the prescribing maxim "if it ain't broke, don't fix it." Three hundred eighteen non-tolerance cases from a university-based Canadian optometric clinic were categorized by a focus group of optometrists. Three prescribing categories were defined and comprised cases in which application of the proposed maxim may have prevented the recheck eye examination; a more limited application of the maxim for one working distance may have been appropriate; and finally scenarios in which the maxim did not work in that the practitioner was judged to have initially followed the maxim, yet patient dissatisfaction was still reported. The remaining unallocated records comprised prescribing situations outside the scope of this study. Approximately 32% of non-tolerance cases were judged to have been preventable by use of the proposed maxim. Furthermore, an additional 10% reduction in recheck cases may have been possible by a more liberal interpretation of the maxim. Conversely, 4% of cases were deemed to comprise scenarios in which the maxim was followed yet the patient returned later to report problems with their spectacles. The prescribing maxim "if it ain't broke, don't fix it" appears to have a role in reducing recheck eye examinations and improving patient satisfaction with new spectacles.

Para ello se revisan aspectos importantes del proceso inflamatorio en estructuras de la boca que como las pulpitis, presentan sus peculiaridades. Se identifica a una de las 2 familias de autacoides provenientes de los fosfolípidos de membrana celular, es decir, los eicosanoides derivados a partir de algunos ácidos grasos polisaturados, en particular, ácido araquidónico, que tras la acción de enzimas da lugar a la formación de prostaglandinas, prostaciclinas, tromboxeno A2 y leucotrienos. Conocidos estos antecedentes, nos ocupamos de fármacos usados para combatir los síntomas y signos de la inflamación. Casi todos los antiinflamatorios no esteroideos utilizados en la actualidad, casi todos, inhiben las actividades de la ciclooxigenasa 1 constitutiva y la ciclooxigenasa 2, inducida en el sitio de la inflamación y con ello, la síntesis de prostaglandinas y tromboxanos. Se alude a la ventaja terapéutica de los inhibidores de la COX-2 que aparecen hoy en el mercado.

    Full Text Available AIM: To study the mechanism of road traffic collisions (RTC, use of safety devices, and outcome of hospitalized pediatric and youth RTC injured patients so as to give recommendations regarding prevention of pediatric RTC injuries. METHODS: All RTC injured children and youth (0-19-year-olds who were admitted to Al Ain City's two major trauma centers or who died after arrival to these centers were prospectively studied from April 2006 to October 2007. Demography of patients, road-user and vehicle types, crash mechanism, usage of safety devices, injured body regions, injury severity, Revised Trauma Score, Glasgow Coma Scale, intensive care unit admissions, hospital stay and mortality were analyzed. RESULTS: 245 patients were studied, 69% were vehicle occupants, 15% pedestrians, 9% motorcyclists and 5% bicyclists. 79% were males and 67% UAE citizens. The most common mechanism of RTC was rollover of vehicle (37% followed by front impact collision (32%. 32 (13% of vehicle occupants were ejected from car. 63% of ejected occupants and 70% of motorcyclists sustained head injuries. Only 2% (3/170 vehicle passengers used seatbelts and 13% (3/23 motorcyclists a helmet. CONCLUSIONS: Male drivers and UAE nationals were at high risk of RTC as drivers and as motorcyclists. Ejection rate was high because safety restraint use was extremely low in our community. More education and law enforcement focusing especially on car/booster seat use is needed.

    Hydrochemical, multivariate statistical, and inverse geochemical modeling techniques were used to investigate the hydrochemical evolution within the Ain Azel aquifer, Algeria. Cluster analysis based on major ion contents defined 3 main chemical water types, reflecting different hydrochemical processes. The first group water, group 1, has low salinity (mean EC = 735 μS/cm). The second group waters are classified as Cl-HCO(3)-alkaline earth type. The third group is made up of water samples, the cation composition of which is dominated by Ca and Mg with anion composition varying from dominantly Cl to dominantly HCO(3) plus SO(4). The varifactors obtained from R-mode FA indicate that the parameters responsible for groundwater quality variations are mainly related to the presence and dissolution of some carbonate, silicate, and evaporite minerals in the aquifer. Inverse geochemical modeling along groundwater flow paths indicates the dominant processes are the consumption of CO(2), the dissolution of dolomite, gypsum, and halite, along with the precipitation of calcite, Ca-montmorillonite, illite, kaolinite, and quartz. © Springer Science+Business Media B.V. 2011

    2013-01-01

    Background Although vitamin D deficiency has been studied in various adult populations, there are few data on the prevalence of this nutritional deficiency among healthy adolescents in the United Arab Emirates (UAE). This study was conducted to determine the prevalence of vitamin D deficiency and to examine its correlates in adolescents aged 15 to 18 years. Methods This was a cross-sectional study in urban schools. Healthy adolescents (N=315) from a sample of 8 schools were randomly selected from the 142 schools in Al Ain, Abu Dhabi Emirate. Outcomes measured included serum concentrations of 25-hydroxy vitamin D (25OHD), plasma lipids, blood sugar, blood pressure and anthropometric data, nutrition and lifestyle variables. Results Fourty-one participants (19.7%) were vitamin D deficient (serum 25OHD level ≤15 ng/mL [≤37.5 nmol/L]. Using a cutoff level of 25(OH) D of ≤20 ng/ml [≤50 nmol/l] 143 participants (45.4%) were vitamin D insufficient. Overall 65.1% of study participants were either vitamin D deficient or insufficient. The prevalence of vitamin D deficiency varied between boys (10%) and girls (28%). In a final multivariate model, serum 25(OH) D concentrations were inversely correlated with female gender, consumption of fast food per week, and body mass index and positively correlated with physical activity scores after adjustment for age. Conclusions Vitamin D deficiency and insufficiency were highly prevalent in adolescents, and more common in girls. PMID:23311702

In Algeria, approximately two thirds of the population is concentrated on the coast which represents only 4 % of the territory. The Mediterranean coast, in particular in Algeria, is subjected to pressures: financial stakes, climatic risks, pollutions and conservation of the water. It is on the basis of the critical and objective report with regard to a wild urbanization of the Algerian coast as well as the influence of the demographic pressure that the choice of the search for this article was held. This publication has for objective to raise (to draw up a current situation (inventory of fixtures of the sector of the environment in Algeria and to present through the case of the coastal city of Oran the consequences of climate change.

    Ain Shams area, Western Arabian Shield, Saudi Arabia, is occupied by four main rock units; gneisses, metavolcanics, metasediments and syn- to post-tectonic granitoids. Field and structural studies reveal that the area was subjected to at least three phases of deformation (D1, D2 and D3). The structural features of the D1 are represented by tight to isoclinal and intrafolial folds (F1), axial plane foliation (S1) and stretching lineations (L1). This phase is believed to be resulted from an early NW-SE contractional phase due to the amalgamation between Asir and Jeddah tectonic terranes. D2 deformation phase progressively overprinted D1 structures and was dominated by thrusts, minor and major F2 thrust-related overturned folds. These structures indicate a top-to-the-NW movement direction and compressional regime during the D2 phase. Emplacement of the syn-tectonic granitoids is likely to have occurred during this phase. D3 structures are manifested F3 folds, which are open with steep to subvertical axial planes and axes moderately to steeply plunging towards the E, ENE and ESE directions, L3 is represented by crenulation lineations and kink bands. These structures attest NE-SW contractional phase, concurrent with the accretion of the Arabian-Nubian Shield (ANS) to the Saharan Metacraton (SM) and the final assembly between the continental blocks of East and West Gondwana.

    Factors that influence performance of community health workers (CHWs) delivering health services are not well understood. A recent logic model proposed categories of support from both health sector and communities that influence CHW performance and program outcomes. This logic model has been used to review a growth monitoring program delivered by CHWs in Honduras, known as Atención Integral a la Niñez en la Comunidad (AIN-C). A retrospective review of AIN-C was conducted through a document desk review and supplemented with in-depth interviews. Documents were systematically coded using the categories from the logic model, and gaps were addressed through interviews. Authors reviewed coded data for each category to analyze program details and outcomes as well as identify potential issues and gaps in the logic model. Categories from the logic model were inconsistently represented, with more information available for health sector than community. Context and input activities were not well documented. Information on health sector systems-level activities was available for governance but limited for other categories, while not much was found for community systems-level activities. Most available information focused on program-level activities with substantial data on technical support. Output, outcome, and impact data were drawn from various resources and suggest mixed results of AIN-C on indicators of interest. Assessing CHW performance through a desk review left gaps that could not be addressed about the relationship of activities and performance. There were critical characteristics of program design that made it contextually appropriate; however, it was difficult to identify clear links between AIN-C and malnutrition indicators. Regarding the logic model, several categories were too broad (e.g., technical support, context) and some aspects of AIN-C did not fit neatly in logic model categories (e.g., political commitment, equity, flexibility in implementation).

The yield was 4.61%, and three fractions of SP (F I, F II and F III eluted with 0.50, 0.75 and 1.00 M of NaCl,respectively, were observed on chromatography profiles; however, differences in charge densities patterns and degree of resolution among them were revealed by electrophoresis. SPs were capable of modifying APTT only in fractions eluted with 0.75 M of NaCl, whose activities were 23.37 and 25.76 IU mg-1, respectively, and the charge density was prerequisite to activity. Therefore, C. cupressoides is a source of SPs possessing low anticoagulant potential compared to HEP.O baixo padrão de qualidade outrora declarado da heparina (HEP para o uso em cirurgias cardíacas tem levado preocupação nos mercados nacional e internacional.

    Background Over the last 30 years the citizens of the United Arab Emirates have experienced major changes in life-style secondary to increased affluence. Currently, 1 in 5 adults have diabetes mellitus, but the associations (clustering) among risk factors, as well as the relevance of the concept of the metabolic syndrome, in this population is unknown. Aim To investigate the prevalence and associations among cardiovascular risk factors in this population, and explore to what extent associations can be explained by the metabolic syndrome according to ATP-III criteria. Method A community based survey, of conventional risk factors for cardiovascular disease was conducted among 817 national residents of Al Ain city, UAE. These factors were fasting blood sugar, blood pressure, lipid profile, BMI, waist circumference, smoking, or CHD family history. Odds ratios between risks factors, both unadjusted and adjusted for age and sex as well as adjusted for age, sex, and metabolic syndrome were calculated. Results Various risk factors were positively associated in this population; associations that are mostly unexplained by confounding by age and sex. For example, hypertension and diabetes were still strongly related (OR 2.5; 95% CI 1.7–3.7) after adjustment. An increased waist circumference showed similar relationship with hypertension (OR 2.3; 95% CI 1.5–3.5). Diabetes was related to an increased BMI (OR 1.5; 96% CI 1.0–2.3). Smoking was also associated with diabetes (OR 1.9, 95% CI 1.0–3.3). Further adjustment for metabolic syndrome reduced some associations but several remained. Conclusion In this population risk-factors cluster, but associations do not appear to be explained by the presence/absence of the ATP-III metabolic syndrome. Associations provide valuable information in planning interventions for screening and management. PMID:19371412

    Floodplain development is associated with lateral accretion along stable channel geometry. Along shifting rivers, the floodplain sedimentation is more complex because of changes in channel position but also cutoff channel presence, which exhibit specific overflow patterns. In this contribution, the spatial and temporal variability of sedimentation rates in cutoff channel infill deposits is related to channel changes of a shifting gravel bed river (Ain River, France). The sedimentation rates estimated from dendrogeomorphic analysis are compared between and within 14 cutoff channel infills. Detailed analyses along a single channel infill are performed to assess changes in the sedimentation rates through time by analyzing activity profiles of the fallout radionuclides 137Cs and unsupported 210Pb. Sedimentation rates are also compared within the channel infills with rates in other plots located in the adjacent floodplain. Sedimentation rates range between 0.65 and 2.4 cm a−1 over a period of 10 to 40 years. The data provide additional information on the role of distance from the bank, overbank flow frequency, and channel geometry in controlling the sedimentation rate. Channel infills, lower than adjacent floodplains, exhibit higher sedimentation rates and convey overbank sediment farther away within the floodplain. Additionally, channel degradation, aggradation, and bank erosion, which reduce or increase the distance between the main channel and the cutoff channel aquatic zone, affect local overbank flow magnitude and frequency and therefore sedimentation rates, thereby creating a complex mosaic of sedimentation zones within the floodplain and along the cutoff channel infills. Last, the dendrogeomorphic and 137Cs approaches are cross validated for estimating the sedimentation rate within a channel infill.

    Two methods of surface improvement widely used in the modern plastics industry are compared, with a view to improving productivity and product quality. Ion implantation of plastics and physical vapour deposition coatings both offer surface engineering advantages. Each method is described and evaluated with reference to plastics moulding. TiAIN coatings are used to protect hard bulk materials, subjected to evenly distributed loads. The more ductile CrN coatings are used for softer materials which give less support to the coatings.

    Los antiinflamatorios no esteroideos (AINES son un grupo heterogéneo de compuestos con actividad analgésica, antipirética y antiinflamatoria que comparten efectos secundarios indeseables, tales como: ulceración gástrica e intestinal, anemia, bloqueo de la agregación plaquetaria, inhibición de la motilidad uterina e hipersensibilidad. Los AINES se utilizan por vía tópica con el fin de aliviar lesiones en tejidos blandos a los cuales puede llegarse directamente a través de la piel, evitando así los efectos colaterales indeseables.

    Actualmente para la gran mayoría de los medicamentos se exige valorar la Biodisponibilidad como criterio de calidad. Biodisponibilidad se define como la cantidad de fármaco que llega a sangre o plasma después de la administración del medicamento que lo contiene y la velocidad a la cual este proceso ocurre; esta determinación de Biodisponibilidad no resulta útil en el caso de medicamentos que se administran a través de la piel y no alcanzan circulación sistémica; la biodisponibilidad relativa o Bioequivalencia es la comparación de las biodisponibilidades de dos medicamentos para determinar si son similares en su comportamiento farmacocinético dentro del organismo.

    El presente trabajo pretende estandarizar y validar un método que permita determinar concentraciones de fármaco en tejidos, en este tipo de medicamentos administrados por vía tópica, que no alcanzan circulación sistémica y por lo tanto no pueden ser cuantificados en sangre o plasma; además pretendemos que esta metodología pueda ser propuesta como una técnica para determinar biodisponibilidad y/o bioequivalencia para este tipo de productos.

    The effects of climate change and overexploitation are being strongly perceived in the studied area and the springs discharge is obviously affected. In this paper, Ras El Ain spring discharge and precipitation were analyzed by normalized methods on an yearly timescale. The deficit of Ras El Ain spring discharge due to overexploitation factors and drought effects was estimated. Cumulative drought analyses were carried out using SPI10 and SQI10. Finally, the decreasing trends of the spring discharge due to the deficiency in rainfall were analyzed. The main results reveal that the annual mean deficit of Ras El Ain spring discharge due to overpumping was between 32 and 45%, whereas, annual mean deficit related to drought was between 22 and 35% on average, during the last 30 years (post-1984). The moving averages of SPI and SQI delineate very well the drought periods during last three decades. The cumulative droughts using SPI10 and SQI10 reveal that wet period (pre-1984) with positive values was characterized by high precipitation and spring discharge. Overexploitation period (1984-1989) is distinguished by decreasing SQI10 values whereas, SPI10 is almost stable. The response of the karst system to the precipitation signal has been changed, during the drought period (1990-2000), and the spring behaviour has been modified due to the first overexploitation period. Finally, overexploitation period (2001-2008) is related to the second phase of groundwater intensive pumping for irrigation purposes. Consequently, this period is completely catastrophic causing the drying up of the spring. The decreasing trends analyzed using DPI and DQI showed annual decreasing rates relative to the mean values of -0.268% and -0.105%, respectively. Thus, the results of theoretical model reveal that precipitation will decrease by about DPI = -20.7% and the discharge will decline by about -9.2% by 2050. Consequently, the declining discharge due to climatic variation under natural conditions as

    In the semiarid central part of Tunisia the water resources are becoming increasingly rare because of the scarcity and irregularity of the precipitation and a steadily growing need for fresh water. This study addresses the use of geochemical and isotopic data to analyze the relationship between the El Haouareb dam and the Ain El Beidha and the Kairouan alluvial plain aquifers systems for durable groundwater management. In the Ain El Beidha basin the hydrogeological and geochemical investigations showed that: - The general direction of the groundwater flow is mainly from the SW to the NE, i.e. towards the hydraulic sill of El Haouareb which allows the connection between the Ain El Beidha basin and the Kairouan plain, - The salinity distribution displays a zonation in apparent relationship with the lithological variation of the aquifer formation, - Mineral exchange between groundwater and the aquifer matrix is the dominant process in determining groundwater salinity. The isotopic data confirm the flow directions of groundwater and shows that the recharge of Ain El Beidha aquifers takes place from the floods of the Khechem and Ben Zitoun wadies and also by preferential infiltration of runoff at the front of hill slopes area. Close to preferential recharge areas, groundwater 3H contents reflect a recent input of surface water, whereas the radiocarbon data indicate a longer residence time downstream. The isotopic characteristics of Ain El Beidha groundwater (small space and temporal changes) authorize the use of averaged values for the dam-aquifer water exchange. Under natural conditions, groundwater recharge of the alluvial aquifer of Kairouan plain occurs by infiltration of the Merguellil floods and from the Ain el Beidha groundwater flow close the karstic hydraulic sills. Since the construction of the El Haouareb dam, these natural mechanisms have been strongly modified: the dam waters infiltrate into the karst, mix with the Ain el Beidha groundwater, and feed the

    2003-01-01

    This work is an attempt to estimate the mean residence time of groundwater in the Ain Al-Tanour and Ain-Samak, which are the major karst springs in the Upper Orontes Basin (Central Syria). This estimate, which consists on the application of a mathematical modeling approach, was based on the use of tritium, as a natural radioisotope tracer and a tool for ground water age dating. By adopting a completely mixed reservoir model, linked with exponential time distribution function, the mean residence time (turnover time) of these two springs was evaluated to be about 50 years. This result is in good agreement with previous estimation obtained for the Figeh main spring, which belongs to the same aquifer (Cenomanian-Turonian complex) in the Damascus Basin. On the basis of this evaluation, a value of about 800 million m 3 was obtained for the maximum groundwater reservoir size

    Full Text Available Defeitos na incorporação de N-glicanos nas proteínas humanas ocasionam um grupo de doenças multissistêmicas denominadas coletivamente distúrbios congênitos de glicosilação (DCG. Os DCG manifestam-se na infância com sintomas neurológicos que incluem principalmente atraso psicomotor, ataxia, hipotonia e episódios de acidente vascular cerebral. Várias proteínas do sistema hemostático somente tornam-se biologicamente ativas após a glicosilação. O objetivo deste estudo foi avaliar os anticoagulantes naturais (proteína S livre, proteína C e antitrombina e os fatores da coagulação (VIII, IX e XI em pacientes com DCG tipo I. Foram avaliados 11 pacientes com diagnóstico positivo para DCG tipo I (três do gênero masculino e oito do gênero feminino, idade média de 5,6 anos; e oito pacientes com diagnóstico negativo para DCG(quatro do gênero masculino e quatro do gênero feminino, idade média de 4,5 anos (grupo-controle. O diagnóstico de DCG tipo I foi realizado pela identificação do padrão de hipoglicosilação da transferrina plasmática. Na avaliação dos anticoagulantes naturais pode-se observar redução dos valores de PS livre e PC e uma redução marcante de AT, quando comparados com o grupo controle. Em relação aos fatores de coagulação não houve diferença significativa para os fatores VIII e IX e houve redução marcante do fator XI. Os resultados do presente estudo sugerem que a deficiência combinada de anticoagulantes naturais é responsável pelo estado pró-trombótico observado em pacientes com DCG. Sugerimos também que a análise dos parâmetros hemostáticos seja realizada para pacientes com DCG quando apresentarem sintomas clínicos de alteração do sistema hemostático e antes de procedimentos invasivos.Defects in the biosynthesis of N-linked human protein glycosylation leads to a group of multisystem disorders collectively called congenital disorders of glycosylation (CDG.

    Full Text Available A incidência de doenças cardiovasculares e os efeitos adversos da heparinoterapia têm motivado a busca por novos agentes terapêuticos e os polissacarídeos sulfatados (PS de algas marinhas têm sido reportados como fontes alternativas para tal. Objetivou-se avaliar o potencial anticoagulante dos PS totais (PST isolados e fracionados das clorofíceas Caulerpa racemosa e Caulerpa cupressoides. Inicialmente, os PST foram extraídos com papaína em tampão acetato de sódio 0,1 M (pH 5,0 contendo cisteína 5 mM e EDTA 5 mM, seguidos de fracionamento em coluna de troca iônica de DEAE-celulose com gradiente de NaCl. As frações obtidas foram analisadas por eletroforese em gel de agarose a 0,5% e a atividade anticoagulante, mensurada pelo tempo de tromboplastina parcial ativada (TTPA, usando-se plasma humano normal e comparada a uma curva-padrão de heparina (193 UI mg-1. Verificaram-se semelhantes perfis cromatográficos entre os PS de ambas as espécies, porém com padrões de mobilidades distintas quando as frações foram comparadas por eletroforese. Os PS modificaram o TTPA, cujas atividades anticoagulantes foram de apenas 21,23 e 24,36 UI mg-1, quando eluídos com 0,75 M de sal para C. racemosa e C. cupressoides, respectivamente. Portanto, PS anticoagulantes isolados das clorofíceas C. racemosa e C. cupressoides resultaram em efeitos anticoagulantes inferiores aos da heparina. Estudos comparativos dessas moléculas também são sugeridos como ferramentas auxiliares na identificação de algas do mesmo gênero.The incidence of cardiovascular diseases and adverse effects from heparintherapy have led to a search for new therapeutic agents, and the sulfated polysaccharides (SP of seaweeds have been reported as alternative sources.

    High solar performance W-AIN cermet solar coatings were designed using a numerical computer model and deposited experimentally. In the numerical calculations aluminium oxynitride (AlON) was used as ceramic component. The dielectric functions and then complex refractive index of W-AlON cermet materials were calculated using the Sheng's approximation. The layer thickness and W metal volume fraction were optimised to achieve maximum photo-thermal conversion efficiency for W-AlON cermet solar coatings on an Al reflector with a surface AlON ceramic anti-reflection layer. Optimisation calculations show that the W-AlON cermet solar coatings with two and three cermet layers have nearly identical solar absorptance, emittance and photo-thermal conversion efficiency that are much better than those for films with one cermet layer. The optimised calculated AlON/W-AlON/Al solar coating film with two cermet layers has a high solar absorptance of 0.953 and a low hemispherical emittance of 0.051 at 80{sup o}C for a concentration factor of 2. The AlN/W-AlN/Al solar selective coatings with two cermet layers were deposited using two metal target direct current magnetron sputtering technology. During the deposition of W-AlN cermet layer, both Al and W targets were run simultaneously in a gas mixture of argon and nitrogen. By substrate rotation a multi-sub-layer system consisting of alternating AlN ceramic and W metallic sub-layers was deposited that can be considered as a macro-homogeneous W-AlN cermet layer. A solar absorptance of 0.955 and nearly normal emittance of 0.056 at 80{sup o}C have been achieved for deposited W-AlN cermet solar coatings. (author)

    A combination of several exploration techniques was carried out at the main phosphatic outcrop of Ain Laylon in the Syrian coastal region. The survey was extended along an E-W profile parallel to Wadi Al-Mzeraa over a distance of about 23 km from Ain Laylon site towards the shoreline of the Mediterranean Sea. The techniques used in this survey included soil radon emanometry, gamma ray spectrometry and soil geochemistry, with the purpose of evaluating the effects of weathering and erosion on the uranium-hearing phosphate formations in the study ares. Soil radon concentration and gamma ray total count rates found to be ranging between 115-472 pCi/l and 52-520 cps over the main phosphate deposit of Ain Layton and between 16-241 pCi/l and 15-300 cps along the profile of Wadi Al-Mzeraa - Rwemiyeh respectively. Some suitable elements such as U, Zn, Pb, Cr, Fe and Sr were also analyzed to trace the dispersion pattern of uranium and its controls throughout the area. The results showed that the distribution of both radon emission and gamma ray activity, in accordance with chemical uranium and some associated trace elements, were almost identical over the study area. The anomalously high values in all cases were basically found to be related to the main phosphatic outcrop and to the reprecipitation processes at their vicinity following the alteration of the phosphates. The prevailing topographic conditions of the drainage system has probably played a crucial role in carrying the uraniferous solutions from its phosphatic source down to the nearby sedimentary environment. This appears to be sufficient enough to produce an anomalous halo resulting in the detection of some relatively high radon and gamma values of about 7 and 15 times the background respectively, especially close to the main phosphate outcrop. A notable gradual decrease was then observed at the following sampling sites along the pathway west of Ain Laylon site approaching the background level at a distance of

    The present work reports a study to increase wear resistance of a ball passage floodgate (steel type T9) trough the application of a thick film (coating). This study have included a material and process selection, synthesis of the coating on steel plates as substrates and spherical device, assembling of the coated floodgate on the ball valves, and finally an evaluation of the valves in the process of a thermoelectric power station. Taking into account the different requirements, a TiAIN coating prepared by cathodic arc evaporation was finally retained. The crystal structure, morphology and chemical composition of the coating were evaluated by x-ray diffraction (XRD) and scanning electron microscopy equipped with an energy dispersive spectrometer (SEM-EDS). Finally, mechanical properties such as hardness and Young modulus were determined by nano indentation. (Author)

    This study aims to assess the impact of water harvesting constructed hydraulic structures (big and small dams, terraces, seuils for recharge…) on the evolution of piezometric head of Ain El Beidha groundwater table. The measurements of depth of water table, taken at the end of rain season and at the end of irrigation season, in many piezometers and monitoring wells, for a long period of observation before and after implementation of all the hydraulic structures, were used with the cumulative rain to the highest water table to diagnostic the effect of natural recharge and constructed hydraulic structures. According to the analysis of curves illustrating the evolution of piezometric head and rainfall over time, it was shown that despite the fact that the same amount of rain fall on the total area in the limits of Ain El Beidha groundwater table, the piezometers respond differently. This is because there are many sources of recharge and many factors affecting the recharge. First of all, the aquifer is divided in four compartments (the calcareous formation of Djebel El Houyareb, the plio-quaternary formation, the Miocene formation: Baglia and Saouaf). All those respond differently to the recharge by their capacity of infiltration and their hydrodynamic characteristics. The recharge of the groundwater table was increased by the implementation of small soil and water conservation structures, artificial lakes, El Haouareb Dam, run off in the natural Oued bads and seuils for recharge installed in the bads of oueds. The different piezometric drown maps were used to determine the flow direction and hydraulic gradient in order to identify the recharge areas, while tracking maps for three equal piezometric heads 210 m 300 m and 370 m established over different years made it possible to assess the impact of hydraulic structures, namely the effect of SWC and Ben Zitoun Lake. To illustrate the impact of El Houareb dam on the groundwater, the piezometric maps and local values

    To evaluate the economic impact of future prescriptions of etanercept and adalimumab biosimilars at the territorial scale covered by PharmAlp'Ain, a hospitals grouping of orders for health products. Determination of the number and status of patients (naive or in continuation of treatment) from the National Database "Datamart de Consommation Inter-Régimes" of health insurance, concerned by a dispensation in a pharmacy of etanercept or adalimumab in 2015. Calculation of potential savings in case of biosimilar requirements according to 3 hypotheses: 63% (rate observed in a previous study) of initiations are treated with biosimiliaries and the others by princeps (H 1 ); all initiations under biosimilars and continuation therapy with the princeps (H 2 ) or all patients are treated with biosimilars (H 3 ). The annual savings are estimated at 237,000 € with the H 1 hypothesis. In the case of H 2 , the expected savings would be 376,200 € per year. In the case of H 3 , savings for the community could reach almost 1,282,800 € per year. The arrival of biosimilars allows significant savings for medicines market. According to the French recommendations in 2016, the expected savings are between the H 1 and H 2 hypothesis. The rate of penetration of biosimilars depends on many factors such as the involvement of health professionals, patient adherence, or health authority recommendations.

    Full Text Available The objective of the present study was to investigate the relationship between time management, perceived stress, gender and academic achievement among United Arab Emirates college students. The respondents were 352 college students from Al Ain University of Science and Technology. The sample was stratified by sex. Among the respondents, 52.5% were female students and 47.5% were male students. The mean age of the sample was 23.4 years ranging from 18 to 39. Time management was measured by Time Management Questionnaire” developed by Britton and Tesser (1991, while perceived stress was measured by The Perceived Stress Scale developed by Cohen (1985. The findings of the study showed that there was statistically significant negative relationship between time management and perceived stress. Females reported higher time management compared to their males counter mates. Higher time management and lower perceived stress were associated with high levels of academic achievement. However, time management was the most significant predictor of academic achievement accounting for 26 % of the variance while perceived stress accounted for an additional 11.2% of the variance in academic achievement. All three predictors explained 29.4% (R = .543 of total variance. The implications and limitations are reviewed as are the suggestions for future research.   Keywords: Time management, perceived stress, academic achievement, college students.

    human settlements and occupation, it is possible to characterize a threefold transition: first, the former transition between the pre-Islamic prehistoric societies and the development of Muslim societies; second, the more recent transition between the traditional historical society (farmers) and the contemporary society, characterized by the growth of urbanization, the creation of modern transport infrastructure and the concomitant growth of tourist flows; third, the current transition between the yesterday and tomorrow Al Ain City, due to the transformation of a local town centred on national economics all along the second half of the twentieth century, into an international town more open to the wider world with the management of a possible increased 20 % of tourist flow because of the inscription of Cultural Sites of Al Ain on the UNESCO's World Heritage List. It is not possible to completely ignore the fact that the Jebel Hafit and its foothills are partly crossed by an international boundary. In case of political tensions, this may cause some difficulties for the management of this territory, with contradictory requirements between security, tourism, traditional land use, and scientific research.

    Introduction Pediatric poisonings represent a major and preventable cause of morbidity and mortality throughout the world. Epidemiologic information about poisoning among children in many lower- and middle-income countries is scarce. This study describes the epidemiology of acute poisonings in children presenting to Ain Shams University's Poisoning Treatment Center (ASU-PTC) in Cairo and determines the causative agents and characteristics of acute poisoning in several pediatric age groups. Methods This retrospective study involved acutely poisoned patients, 0 to 18 years of age, who presented to the ASU-PTC between 1/1/2009 and 12/31/2013. Data were extracted from electronic records maintained by the ASU-PTC. Collected data included demographics, substance of exposure, circumstances of the poisoning, patient disposition, and outcome. Results During the 5-year study period, 38,470 patients meeting our criteria were treated by the ASU-PTC; 19,987 (52%) were younger than 6 years of age; 4,196 (11%) were 6 to 12 years; and 14,287 (37%) were >12 years. Unintentional poisoning accounted for 68.5% of the ingestions, though among adolescents 84.1% of ingestions were with self-harm intent. In all age groups, the most frequent causative drugs were non-opioid analgesics, antipyretics, and antirheumatics. The most common nonpharmaceutical agents were corrosives in preschool children and pesticides in adolescents. Most patients had no/minor effects (29,174 [75.8%]); hospitalization rates were highest among adolescents. There were 119 deaths (case fatality rate of 0.3), primarily from pesticide ingestion. Conclusion Poisoning in preschool children is mainly unintentional and commonly due to nonpharmaceutical agents while poisoning in adolescents is mainly intentional (self-harm). Pesticides, mainly organophosphorous compounds and carbamates, were the most frequent agent leading to morbidity and mortality. PMID:26653953

    Full Text Available This article positions the translations of French verse works (plays and selected collections of individual poets that August Sang, Jaan Kross and Ain Kaalep made in the 1960s, onto the background of their own original works. At that time, August Sang translated four plays by Molière (The Misanthrope, Tartuffe, The School for Wives in 1961; Amphitryon in 1961, which have already been discussed in relation to the tradition of translating the French syllabic verse into Estonian, because these translations form a considerable part of the body of Estonian translations of French verse poetry. For Jaan Kross and Ain Kaalep, the wider context is created by the so-called free verse battles in the 1950s, to which we can link Kross’ translation of a selected collection of Éluard (Veel enne kostma peab, 1969 and Kaalep’s translation of a selected collection of Prévert (Kuidas portreteerida lindu, 1965. One of the two remaining translations by Kross, (Rostand’s Cyrano de Bergerac, 1964, can also be examined in relation to the problems of translating verse, but the other, (Béranger’s Laulud, 1963, should be discussed in the framework of intellectual and cultural resistance, a part of which was also the struggle put up for the existence of free verse in the 1950s and 1960s. Of August Sang’s original work, the article examines his collection of poems Võileib suudlusega (1963, written simultaneously with his translations of Molière’s plays and published right after them. Both the translations and the collection of original poems have attracted critics’ attention with their remarkable lack of linguistic constraint and simplicity. Although Sang has rarely voiced theoretical ideas about translation or explained his method, both his poetic image, outlined in the collection Võileib suudlusega, and his search for right words, reflected in the drafts of his translations, let us believe that the simplicity of expression and the avoidance of marked

    A bacterial strain E21 was isolated from a sample of water collected in the salt lake located close to Ain Salah, Algeria. The analysis of 16S rRNA gene sequence had indicated that the strain had 93 % sequence similarity with the genus Natrialba sp. strain E21 (GenBank, FR750525.1) and was considered extremely halophilic. Production of biosurfactant by the strain E21 with free and entrapped cells was investigated using soluble starch in the saline conditions. Biosurfactant synthesis was followed by measuring the surface tension and emulsifying index 9 days under optimal conditions (40 °C, pH 7). Some diffusional limitations in alginate and agar beads affected the kinetics of biosurfactant production when compared to that obtained with free cells culture. The minimum values of surface tension were 27 and 30 mN m(-1) achieved after 9 days with free and immobilized cells, respectively, while the corresponding maximum E24 values were 65.3 and 62.3 %, respectively. The re-use of bacterial cells along with the limited cell losses provided by the immobilized system might lead to significant reduction of the biosurfactant production cost.

    Full Text Available Au Maroc, l’utilisation des eaux souterraines pour l’irrigation a permis un développement agricole rapide dans de nombreuses régions, mais a aussi fait émerger des situations de baisse des niveaux piezométriques des nappes qui menacent la durabilité de cette agriculture irriguée. L’article présente une action de recherche portant sur la conception d’un projet de territoire agricole durable alliant développement agricole et usage pérenne des ressources en eau souterraine. L’étude a eu lieu dans la zone d’Ain Timguenay (province de Séfrou, qui connait un fort développement de la production de pommes et de prunes depuis une quinzaine d’années. Le programme de recherche a impliqué les agriculteurs, la commune rurale d’Ain Timguenay, les institutions du Ministère de l’Agriculture et l’Agence de bassin hydraulique du Sébou. Une analyse des dynamiques agricoles locales et des tendances nationales a servi de support aux discussions. L’étude de l’aquifère et de ses usages a permis d’établir un bilan sommaire et un ordre de grandeur des surfaces qui pourraient encore être plantées sans que les consommations en eau soient supérieures à la recharge de l’aquifère en année pluviométrique moyenne. Une réflexion prospective menée avec les agriculteurs a mis en évidence deux scénarios possibles à l’échelle locale: 1 un scénario où les difficultés économiques que rencontrent actuellement les exploitations de la zone se renforcent, conduisant à un ralentissement des nouvelles plantations, d’où une pression limitée sur la nappe ; 2 un scénario où les exploitations réussissent à faire face aux défis actuels de production et de commercialisation et de ce fait continuent à planter, ce qui conduit à une consommation en eau bien supérieure à la recharge de la nappe. L’ensemble des acteurs impliqués a participé à l’élaboration d’un troisième scénario permettant de concilier d

    The extraction of uranium on the trace level is studied by using tributylphosphate as active agent under conditions aiming the attainment of quantitative extraction by means of a single step process using a number of salting-out agents and keeping inside the general lines as reported in two precedent papers. Two inert solvents were investigated, benzene and cyclohexane, which allowed to derive the corresponding empirical equations describing the extraction process and the results obtained were compared with those previously reported for solvents which, like ethyl acetate and methylisobuthylketone, favour to a more or less extend the extraction of uranium.

    Peptic ulcer etiology has been changing because of H. pylori decline. To estimate peptic ulcer prevalence in 10 years-interval and compare the association with H. pylori and use of non-steroidal anti-inflammatory drugs. Methods Records assessment in two periods: A (1997-2000) and B (2007-2010), searching for peptic ulcer, H. pylori infection and non-steroidal anti-inflammatory drugs use. Peptic ulcer occurred in 30.35% in A and in 20.19% in B. H. pylori infection occurred in 73.3% cases in A and in 46.4% in B. Non-steroidal anti-inflammatory drugs use was 3.5% in A and 13.3% in B. Neither condition occurred in 10.4% and 20.5% in A and B respectively. Comparing both periods, we observed reduction of peptic ulcer associated to H. pylori (P=0.000), increase of peptic ulcer related to non-steroidal anti-inflammatory drugs (P=0.000) and idiopathic peptic ulcer (P=0.002). The concurrent association of H. pylori and non-steroidal anti-inflammatory drugs was also higher in B (P=0.002). Rates of gastric ulcer were higher and duodenal ulcer lower in the second period. After 10 years, the prevalence of peptic ulcer decreased, as well as ulcers related to H. pylori whereas ulcers associated to non-steroidal anti-inflammatory drugs increased. There was an inversion in the pattern of gastric and duodenal ulcer and a rise of idiopathic peptic ulcer.

  3. The cytometric future: it ain't necessarily flow!

    2011-01-01

    Initial approaches to cytometry for classifying and characterizing cells were based on microscopy; it was necessary to collect relatively high-resolution images of cells because only a few specific reagents usable for cell identification were available. Although flow cytometry, now the dominant cytometric technology, typically utilizes lenses similar to microscope lenses for light collection, improved, more quantitative reagents allow the necessary information to be acquired in the form of whole-cell measurements of the intensities of light transmission, scattering, and/or fluorescence.Much of the cost and complexity of both automated microscopes and flow cytometers arises from the necessity for them to measure one cell at a time. Recent developments in digital camera technology now offer an alternative in which one or more low-magnification, low-resolution images are made of a wide field containing many cells, using inexpensive light-emitting diodes (LEDs) for illumination. Minimalist widefield imaging cytometers can provide a smaller, less complex, and substantially less expensive alternative to flow cytometry, critical in systems intended for in resource-poor areas. Minimalism is, likewise, a good philosophy in developing instrumentation and methodology for both clinical and large-scale research use; it simplifies quality assurance and compliance with regulatory requirements, as well as reduces capital outlays, material costs, and personnel training requirements. Also, importantly, it yields "greener" technology.

    Phase stability, oxidation resistance and great mechanical properties are the main objectives when synthesizing protective coatings. The tantalum nitride (TaN) has aroused interest because of its high temperature stability, chemical inertness and thermal conductivity. However, it has a low hardness value when compared to other coatings. Researches has shown that one way to improvements in the properties of a thin film is by adding other elements in the deposition process. Therefore, the objective of this study was to deposit thin films of TaAlN by magnetron sputtering, changing the aluminum concentration of 2, 5, 7, to 14%. Then the coatings were characterized by EDS, RBS, GIXRD and nanohardness. In this study was found that the aluminum deposited did not change the oxidation resistance of the coating, and the highest value of hardness was 28 GPa for the sample with 14 at.%. (author)

    The obtention of copper from primary resources by solvent extraction has been developed continuously over the past 25-30 years, entailing a continuous effort both of research and development and being one of the biggest successes in the industrial development of a given metal. The success of this operation was not possible without the corresponding developments, at the same time, of the two accompanying operations (leaching and electro wining), which perfectly coupled in the operational sequence. The recovery of copper by means of these hydrometallurgical processes is firmly established and being reflecting in the growing number of operational plants under construction and/or commissioned until the beginning of the XXI century. This work presents data on the successfully application of the sequence of operations on the recovery of a metal: copper (Author) 19 refs.

    Full Text Available Measurements of molar volume, refraction index and dynamic viscosity in mixtures of fatty acids or triglycerides and trichloroethylene, tetrachloroethylene and hexane were realized. Temperature range studied was 278-313 K each 5 K. The relationship between molar volume and molar fraction show high correlation coefficient In fatty acids with trichloroethylene and tetrachloroethylene mixtures. On the other hand, hexane mixtures show little contractions of molar volume at low molar fractions. Triglyceride mixtures present important deviations with regard to the ideality of the molar volume. The adjusts obtained for the molar volume values versus temperature are acceptable, calculating the coefficients of thermal expansion of the studied mixtures. Equally, the adjust of the experimental results of viscosity for two prediction equations are studied: one of additive type and the other of parabolic type.

    Se han realizado medidas del volumen molar, índice de refracción y viscosidad dinámica en el intervalo de temperatura de 278 K a 313 K cada 5 K, a mezclas de ácidos grasos o triglicéridos con tricloroetileno, tetracloroetileno y hexano. Las mezclas de ácidos grasos con tricloroetileno y tetracloroetileno, presentan unos altos coeficientes de correlación para los valores del volumen molar frente a la fracción molar, mientras que las mezclas con hexano, a fracciones molares bajas, manifiestan una pequeña contracción del volumen molar. Las mezclas de triglicéridos presentan importantes desviaciones con respecto a la Idealidad del volumen molar. Los ajustes obtenidos para los valores del volumen molar frente a la temperatura son aceptables, determinándose los valores del coeficiente de dilatación volumétrica a presión constante de las mezclas estudiadas. Igualmente se ha estudiado el ajuste de los resultados experimentales de viscosidad a dos ecuaciones de predicción: una del tipo aditiva y otra del tipo parabólico.

    The cost effective provision of quality care for chronic diseases is a major challenge for health care systems. We describe a project to improve the care of patients with the highly prevalent disorders of diabetes and hypertension, conducted in one of the major cities of the United Arab Emirates. The project, using the principles of quality assurance cycles, was conducted in 4 stages.The assessment stage consisted of a community survey and an audit of the health care system, with particular emphasis on chronic disease care. The information gleaned from this stage provided feedback to the staff of participating health centers. In the second stage, deficiencies in health care were identified and interventions were developed for improvements, including topics for continuing professional development.In the third stage, these strategies were piloted in a single health centre for one year and the outcomes evaluated. In the still ongoing fourth stage, the project was rolled out to all the health centers in the area, with continuing evaluation. The intervention consisted of changes to establish a structured care model based on the predicted needs of this group of patients utilizing dedicated chronic disease clinics inside the existing primary health care system. These clinics incorporated decision-making tools, including evidence-based guidelines, patient education and ongoing professional education. The intervention was successfully implemented in all the health centers. The health care quality indicators that showed the greatest improvement were the documentation of patient history (e.g. smoking status and physical activity); improvement in recording physical signs (e.g. body mass index (BMI)); and an improvement in the requesting of appropriate investigations, such as HbA1c and microalbuminurea. There was also improvement in those parameters reflecting outcomes of care, which included HbA1c, blood pressure and lipid profiles. Indicators related to lifestyle changes, such as smoking cessation and BMI, failed to improve. Chronic disease care is a joint commitment by health care providers and patients. This combined approach proved successful in most areas of the project, but the area of patient self management requires further improvement.

  13. The Danish health care system: it ain't broke... so don't fix it.

    The organisation and financing of the Danish health care system was evaluated within a framework of analysis of strengths, weaknesses, opportunities and threats (a SWOT analysis) by a panel of five members with a background in health economics. The evaluation was based on reading an extensive amount of selected documents and literature on the Danish health care system, and a 1 week-visit to health care authorities, providers and key persons. This paper includes the main findings by one of the panel members. The international competition 'wave' passed by Denmark, and the Danish might rightly say 'thank goodness'. Funding is very largely public and there is a single dominant authority, i.e. the county, which makes planning easier. Low levels of patient payments and the smaller size of the private sector reflect Danish 'solidarity' and promote equity. Planning is good. Exceptions to this are the over-concern with hospital waiting lists and the flirting with DRG based funding. Greater investment in planning approaches would make the system yet better. The GP blended remuneration system with capitation and fee for service is a major strength. The fact that the system has such potential for technical and allocative efficiency and also equity but is not fully exploited suggests the need for more investment in health services research. While there is scope for improving the health care system in Denmark, the rest of the world has as much to learn from the Danes as the Danes have from the rest of the world.

    The objective of this work was to study NbAlN thin films and the influence of variation in the concentration of aluminum in the crystal structure and oxidation resistance of these coatings. The thin films were deposited by reactive magnetron sputtering and characterized by Grazing Incidence X-ray Diffraction (GIXRD), Energy Dispersive Spectroscopy (EDS) and oxidation tests at high temperatures. NbAlN thin films were deposited and present at concentration of 10, 20 and 42 at% Al. The NbAlN crystalline phase obtained was the δ-NbN, however it was observed a shift of the peaks in the patterns obtained GIXRD of regions for larger angles for these samples, indicating the formation of a solid solution. The higher oxidation resistance temperature was 700° C for the sample with 42 in at% Al. From the SEM analysis it was possible to observe the surface of the film after oxidation, all films showed defects, however the amount of such defects was lower in samples with higher aluminum concentrations.

    The objective of this project is to apply whole-tree harvesting method to Finnish timber harvesting conditions in order to lower the harvesting costs of energy wood and timber in spruce-dominant final cuttings. In Finnish conditions timber harvesting is normally based on the log-length method. Because of small landings and the high level of thinning cuttings, whole-tree skidding methods cannot be utilised extensively. The share of stands which could be harvested with whole-tree skidding method showed up to be about 10 % of the total harvesting amount of 50 mill. m{sup 3}. The corresponding harvesting potential of energy wood is 0,25 Mtoe. The aim of the structural measurements made in this project was to get information about the effect of different hauling methods into the structural response of the tractor, and thus reveal the possible special requirements that the new whole-tree skidding places forest tractor design. Altogether 7 strain gauge based sensors were mounted into the rear frame structures and drive shafts of the forest tractor. Five strain gauges measured local strains in some critical details and two sensors measured the torque moments of the front and rear bogie drive shafts. Also the revolution speed of the rear drive shaft was recorded. Signal time histories, maximum peaks, Time at Level distributions and Rainflow distributions were gathered in different hauling modes. From these, maximum values, average stress levels and fatigue life estimates were calculated for each mode, and a comparison of the different methods from the structural point of view was performed

  16. "Ain't no one here but us social forces": constructing the professional responsibility of engineers.

    Science.gov (United States)

    Davis, Michael

    2012-03-01

    There are many ways to avoid responsibility, for example, explaining what happens as the work of the gods, fate, society, or the system. For engineers, "technology" or "the organization" will serve this purpose quite well. We may distinguish at least nine (related) senses of "responsibility", the most important of which are: (a) responsibility-as-causation (the storm is responsible for flooding), (b) responsibility-as-liability (he is the person responsible and will have to pay), (c) responsibility-as-competency (he's a responsible person, that is, he's rational), (d) responsibility-as-office (he's the responsible person, that is, the person in charge), and (e) a responsibility-as-domain-of-tasks (these are her responsibilities, that is, the things she is supposed to do). For all but the causal sense of responsibility, responsibility may be taken (in a relatively straightforward sense)-and generally is. Why then would anyone want to claim that certain technologies make it impossible to attribute responsibility to engineers (or anyone else)? In this paper, I identify seven arguments for that claim and explain why each is fallacious. The most important are: (1) the argument from "many hands", (2) the argument from individual ignorance, and (3) the argument from blind forces. Each of these arguments makes the same fundamental mistake, the assumption that a certain factual situation, being fixed, settles responsibility, that is, that individuals, either individually or by some group decision, cannot take responsibility. I conclude by pointing out the sort of decisions (and consequences) engineers have explicitly taken responsibility for and why taking responsibility for them is rational, all things considered. There is no technological bar to such responsibility. © Springer Science+Business Media B.V. 2010

    GaN and related structures attracted a great interest in the recent years for electronic and optoelectronic applications due to their promising properties. GaN is grown popularly on foreign substrates like sapphire and SiC. However, silicon due to its favourable properties attended the great attention of material scientists and researchers to utilize as substrate for heteroepitaxy of GaN based structures and devices. Silicon substrates are low cost, available in large diameters and have well characterized thermal and electrical properties. In this study, GaN/AlN/Si(111) heterostructures were grown by molecular beam epitaxy. We performed x-ray diffraction spectroscopy and spectroscopic ellipsometry on these samples to study their structural and optical properties. XRD measurements performed on these samples revealed the presence of high quality GaN films as well as the presence of AlN buffer layer with the following miller indices: GaN (002), GaN (004), GaN (006) and GaN (110) along with Si peak of phase (111). The ellipsometric data obtained were used to characterize the GaN/Si samples as a function of film thickness. Refractive index, extinction coefficient and dielectric constant were calculated by the measured data. (author)

    Phase stability, oxidation resistance and great mechanical properties are the main objectives when synthesizing protective coatings. The tantalum nitride (TaN) has aroused interest because of its high temperature stability, chemical inertness and thermal conductivity. However, it has a low hardness value when compared to other coatings. Researches has shown that one way to improvements in the properties of a thin film is by adding other elements in the deposition process. Therefore, the objective of this study was to deposit thin films of TaAlN by magnetron sputtering, changing the aluminum concentration of 2, 5, 7, to 14%. Then the coatings were characterized by EDS, RBS, GIXRD and nanohardness. In this study was found that the aluminum deposited did not change the oxidation resistance of the coating, and the highest value of hardness was 28 GPa for the sample with 14 at.%. (author)

    Full Text Available The use of ceramic materials like titanium and aluminium nitrides have experienced a great improvement in the last years due to the variety of applications they show. The use as protective coatings on industrial tools is one important application with very favorable results for the moment, as it is the use as coating molds used for different elements fabrication. One of the mostly often used techniques to deposit protective coatings is the sputtering technique, which has been used in this work. In the present study we have analysed structural and mechanical properties of TiN and AlN thin films, using X-Ray diffraction, scanning electron microscopy, nanoindentation and pin-on-disk techniques. Thermal treatments have been applied on the mentioned films, applying three different temperature values: 750oC, 850oC y 950oC. Changes in their properties before and after the treatments have been observed. TiN layers show a thermal resistance around 750oC. The thermal resistance for AlN layers is around 850oC, being also observed an improvement in their properties when applying 850ºC of thermal treatment.

    La utilización de materiales cerámicos como el nitruro de titanio o de aluminio ha experimentado una gran popularización en los últimos años gracias a su gran variedad de aplicaciones. Una importante aplicación que cuenta hasta el momento con resultados muy favorables es la de su uso como recubrimientos protectores de herramientas industriales, así como de moldes empleados en la fabricación de diferentes elementos. Una de las técnicas más utilizadas en la obtención de recubrimientos protectores es la técnica de sputtering, utilizada en este trabajo. En el presente estudio se han analizado las propiedades estructurales y mecánicas de láminas delgadas de TiN y AlN mediante las técnicas de difracción de rayos X, microscopía electrónica de barrido, nanoindentación y pin-on-disk.

    Ochratoxin A (OTA) is potently nephrotoxic, teratogenic and carcinogenic, and the potency was varied markedly between species and sexes. Unfortunately, OTA are present due to mold contamination in different food stuffs such as coffee bean, therefore, the present study was carried out on collected imported coffee samples from super markets in Egypt. The isolation and identification proved presence of Penicilli sp. and Aspergillus sp. whereas the last one was dominant in two samples as A. niger and A. ochoruses. Determination of OTA by using HPLC analysis showed presence of high levels than the allowance levels in green coffee beans (more than 5 μg/kg; ppb). In addition, another group of collected samples as roasted coffee beans indicated the presence of high toxic concentrations of OTA. The study was then conducted on samples contain the highest OTA content by using some physical methods as gamma irradiation (5 and 10 kGy), charcoal (powder, granules), roasting (at 200 0 C for 7-10 min and 20 min). The results showed that proposed physical methods, mainly gamma irradiation and charcoal, could be efficient to decrease OTA in green beans coffee without produce toxic substance as well as non-significant changes in its properties. In addition, safety of resulted coffee beans after treatments were checked by ESR and genotoxicity test, which raise the preferability of gamma irradiation (10 kGy) treatment before using medium roasting to get coffee beans free from OTA

    A completely new type of actuator - one that is proposed for use in a variety of environments from sea to land to air to space - has been designed, patented, built, and tested. The actuator is loosely based on the principle of the internal combustion engine, except that it is a completely closed system, only requiring electrical input, and the working fuel is water. This paper outlines the theory behind the electrolysis- and ignition-based cycle upon which the actuator operates and describes the performance capability test apparatus and results for the actuator. A mechanism application that harnessed the unit s power to twist a scaled rotor blade is also highlighted.

    2017-02-01

    UV-LEDs are of great interest for applications like disinfection, gas sensing, and phototherapy. The cost sensitive LEDs are commonly grown by MOVPE on transparent AlN/sapphire templates. The large thermal and lattice mismatch between AlN and sapphire generates a very high dislocation density (DD) and causes big challenges in strain management. The threading dislocation density should be reduced to the order of low 108cm-2 for high internal efficiency of the AlGaN based UV-LED structures. The TDD will be reduced mainly by dislocation annihilation during the growth of thick Al(Ga)N layers, which is a challenge in terms of strain management. We present how in-situ reflectometry and curvature measurement (EpiCurveTT(at)LayTec) in commercial multiwafer growth reactors helps to optimize the growth processes concerning growth rates, surface roughening and avoidance of layer cracking on 2inch substrates and enhance the reproducibility of epitaxial growth. The growth of up to 3 μm thick planar AlN templates and up-to 10 μm thick AlN/sapphire templates by epitaxial lateral overgrowth of stripe patterned templates for UV-C LED structures will be highlighted. The implementation of different types of AlN/GaN superlattices for the subsequent growth of up to 5μm thick Al0.5Ga0.5N layer for UVB LED structures will be shown. Correlations to ex-situ measurements like X-ray diffraction and TEM analysis of defects in the LED structures will be shown. Some challenges of in-situ control through very narrow viewports as in Close Coupled Showerhead reactors will be discussed as well as the influence of silicon doping on curvature and dislocation density in Al(Ga)N layers.

    Although psychological theories outline that it might be beneficial to set more challenging goals, people attempting to lose weight are generally recommended to set modest weight loss goals. The present study explores whether the amount of weight loss individuals strive for is associated with more positive psychological and behavioral outcomes. Hereto, 447 overweight and obese participants trying to lose weight completed two questionnaires with a 2-month interval. Many participants set goals that could be considered unrealistically high. However, higher weight loss goals did not predict dissatisfaction but predicted more effort in the weight loss attempt, as well as more self-reported short-term weight loss when baseline commitment and motivation were controlled for.

  14. The application of magnetic self-filter to optimization of AIN film growth process during the impulse plasma deposition synthesis

    2016-03-01

    Full Text Available This work presents the very first results of the application of plasma magnetic filtering achieved by a coil coupled with an electrical circuit of a coaxial accelerator during the synthesis of A1N thin films by use of Impulse Plasma Deposition method (IPD. The uniqueness of this technical solution lies in the fact that the filter is not supplied, controlled and synchronized from any external device. Our solution uses the energy from the electrical circuit of plasma accelerator. The plasma state was described on the basis of OES studies. Estimation of the effects of plasma filtering on the film quality was carried out on the basis of characterization of structure morphology (SEM, phase and chemical composition (vibrational spectroscopy. Our work has shown that the use of the developed magnetic self-filter improved the structure of the AlN coatings synthesized under the condition of impulse plasma, especially by the minimization of the tendency to deposit metallic aluminum droplets and columnar growth.

    We report the preparation and stability of ScVO 3.5+x and the novel phase InVO 3.5+x . AVO 3.5+x (A=Sc, In) defect fluorite structures are formed as metastable intermediates during the topotactic oxidation of AVO 3 bixbyites. The oxidation pathway has been studied in detail by means of thermogravimetric/differential thermal analysis and in-situ powder X-ray diffraction. The oxidation of the bixbyite phase follows a topotactic pathway at temperatures between 300 and 400 deg. C in air/carbon dioxide. The range of accessible oxygen stoichiometries for the AVO 3.5+x structures following this pathway are 0.00≤x≤0.22. Rietveld refinements against powder X-ray and neutron data revealed that InVO 3.54 and ScVO 3.70 crystallize in the defect fluorite structure in space group Fm-3 m (227) with a=4.9863(5) and 4.9697(3)A, respectively with A 3+ /V 4+ disorder on the (4a) cation site. Powder neutron diffraction experiments indicate clustering of oxide defects in all samples. Bulk magnetic measurements showed the presence of V 4+ and the absence of magnetic ordering at low temperatures. Powder neutron diffraction experiments confirmed the absence of a long range ordered magnetic ground state. - Graphical abstract: Topotactic oxidation of AVO 3 bixbyite to AVO 3.5 defect fluorite structure followed by in-situ powder X-ray diffraction. The upper structural diagram shows a six coordinated (A/V)-O 6 fragment in bixbyite, the lower structure illustrates the same seven-fold coordinated (A/V)-O 7 cubic environment in the defect fluorite structure

Narrative review. We applied the following criteria to each meta-analysis: (1) whether each meta-analysis was described accurately, adequately, and transparently in the article; (2) whether there was an adequate attempt to deal with methodological quality of the original trials; (3) the extent to which the meta-analysis depended on small, underpowered studies; and (4) the extent to which the meta-analysis provided valid and useful evidence-based recommendations. Across the four meta-analyses, we identified substantial problems with the transparency and completeness with which these meta-analyses were reported, as well as a dependence on small, underpowered trials of generally poor quality. Results of our exercise raise questions about the clinical validity and utility of the conclusions of these meta-analyses. Results should serve as a wake up call to prospective authors, reviewers, and end-users of meta-analyses now appearing in the literature. Copyright 2010 APA, all rights reserved.

  13. A New Look at Shelter 131/51 in the Natufian Site of Eynan (Ain-Mallaha, Israel.

    Directory of Open Access Journals (Sweden)

    Gil Haklay

    Full Text Available In the past 25 years since the reconstruction of Shelter 131 of Eynan was suggested by Francois Valla, its image has become almost iconic--a highly cited symbol of early sedentism constituting a significant part of our knowledge on early stone constructions and the people behind them. A new look at the architectural remains and the stratigraphy resulted in an alternative reconstruction, essentially different than the one we have come to know. We used spatial (architectural-geometrical analysis in order to study the relationships between the different architectural elements and to test our hypothesis that the series of postholes may have not pertained to the upper floor 131 of Layer IV as suggested by Perrot and Valla, but rather to the successive occupational and architectural episode. The association of the postholes with Wall 51 of Layer III sheds new light on the architectural remains revealing their geometric design, an important characteristic of Early Natufian Architecture, the meaning and implications of which we shortly discuss.

  17. Straight talk about high-fructose corn syrup: what it is and what it ain't.

    Science.gov (United States)

    White, John S

    2008-12-01

    High-fructose corn syrup (HFCS) is a fructose-glucose liquid sweetener alternative to sucrose (common table sugar) first introduced to the food and beverage industry in the 1970s. It is not meaningfully different in composition or metabolism from other fructose-glucose sweeteners like sucrose, honey, and fruit juice concentrates. HFCS was widely embraced by food formulators, and its use grew between the mid-1970s and mid-1990s, principally as a replacement for sucrose. This was primarily because of its sweetness comparable with that of sucrose, improved stability and functionality, and ease of use. Although HFCS use today is nearly equivalent to sucrose use in the United States, we live in a decidedly sucrose-sweetened world: >90% of the nutritive sweetener used worldwide is sucrose. Here I review the history, composition, availability, and characteristics of HFCS in a factual manner to clarify common misunderstandings that have been a source of confusion to health professionals and the general public alike. In particular, I evaluate the strength of the popular hypothesis that HFCS is uniquely responsible for obesity. Although examples of pure fructose causing metabolic upset at high concentrations abound, especially when fed as the sole carbohydrate source, there is no evidence that the common fructose-glucose sweeteners do the same. Thus, studies using extreme carbohydrate diets may be useful for probing biochemical pathways, but they have no relevance to the human diet or to current consumption. I conclude that the HFCS-obesity hypothesis is supported neither in the United States nor worldwide.

  18. Development of Production PVD-AIN Buffer Layer System and Processes to Reduce Epitaxy Costs and Increase LED Efficiency

    Energy Technology Data Exchange (ETDEWEB)

    Cerio, Frank

    2013-09-14

    The DOE has set aggressive goals for solid state lighting (SSL) adoption, which require manufacturing and quality improvements for virtually all process steps leading to an LED luminaire product. The goals pertinent to this proposed project are to reduce the cost and improve the quality of the epitaxial growth processes used to build LED structures. The objectives outlined in this proposal focus on achieving cost reduction and performance improvements over state-of-the-art, using technologies that are low in cost and amenable to high efficiency manufacturing. The objectives of the outlined proposal focus on cost reductions in epitaxial growth by reducing epitaxy layer thickness and hetero-epitaxial strain, and by enabling the use of larger, less expensive silicon substrates and would be accomplished through the introduction of a high productivity reactive sputtering system and an effective sputtered aluminum-nitride (AlN) buffer/nucleation layer process. Success of the proposed project could enable efficient adoption of GaN on-silicon (GaN/Si) epitaxial technology on 150mm silicon substrates. The reduction in epitaxy cost per cm{sup 2} using 150mm GaN-on-Si technology derives from (1) a reduction in cost of ownership and increase in throughput for the buffer deposition process via the elimination of MOCVD buffer layers and other throughput and CoO enhancements, (2) improvement in brightness through reductions in defect density, (3) reduction in substrate cost through the replacement of sapphire with silicon, and (4) reduction in non-ESD yield loss through reductions in wafer bow and temperature variation. The adoption of 150mm GaN/Si processing will also facilitate significant cost reductions in subsequent wafer fabrication manufacturing costs. There were three phases to this project. These three phases overlap in order to aggressively facilitate a commercially available production GaN/Si capability. In Phase I of the project, the repeatability of the performance was analyzed and improvements implemented to the Veeco PVD-AlN prototype system to establish a specification and baseline PVD-AlN films on sapphire and in parallel the evaluation of PVD AlN on silicon substrates began. In Phase II of the project a Beta tool based on a scaled-up process module capable of depositing uniform films on batches of 4”or 6” diameter substrates in a production worthy operation was developed and qualified. In Phase III, the means to increase the throughput of the PVD-AlN system was evaluated and focused primarily on minimizing the impact of the substrate heating and cooling times that dominated the overall cycle time.

    Reed, Sarah J; Valenti, Maria T

    2012-01-01

    This article explores the ways in which young, Black lesbians manage their sexual minority identity when experiencing sexual prejudice. Fourteen Black lesbians between the ages of 16 and 24 participated in semistructured interviews. Instances of sexual prejudice and the young women's responses were thematically analyzed using open and axial qualitative coding techniques. Results indicated that participants experienced sexual prejudice frequently and even within the lesbian community. Responses to sexual prejudice included: cognitive reframing of heterosexist messages, passing, gaining support from self-created gay families, and fighting back (physically and verbally) in the event of isolated instances of sexual prejudice. Analysis focuses on how gender identity relates to experiences of sexual prejudice and identity management strategies. Findings suggest that there are parallels between the management strategies of these women and young, Black gay and bisexual males and between these women and Black women who are coping with sexism and racism.

  2. Nitric oxide as a mediator of gastrointestinal mucosal injury?—Say it ain't so

    Directory of Open Access Journals (Sweden)

    Paul Kubes

    1995-01-01

    Full Text Available Nitric oxide has been suggested as a contributor to tissue injury in various experimental models of gastrointestinal inflammation. However, there is overwhelming evidence that nitric oxide is one of the most important mediators of mucosal defence, influencing such factors as mucus secretion, mucosal blood flow, ulcer repair and the activity of a variety of mucosal immunocytes. Nitric oxide has the capacity to down-regulate inflammatory responses in the gastrointestinal tract, to scavenge various free radical species and to protect the mucosa from injury induced by topical irritants. Moreover, questions can be raised regarding the evidence purported to support a role for nitric oxide in producing tissue injury. In this review, we provide an overview of the evidence supporting a role for nitric oxide in protecting the gastrointestinal tract from injury.

  3. If it ain't broke, don't price fix it: the OFT and the PPRS.

    2007-07-01

    The Office of Fair Trading (OFT) Report on the UK Pharmaceutical Price Regulation Scheme (PPRS) recommends that when the current five-year PPRS expires in 2010 it be replaced with 'value-based pricing' which involves pre-launch centralised government price setting based on a cost-per-QALY threshold plus periodic ex post reviews. I examine the validity of the OFTs criticisms of the existing PPRS, review its proposals and propose an alternative way forward. I conclude that PPRS has performed well as a procurement bargain between industry and the UK government. It does not, however, incentivise efficient relative prices. That is not its job. I identify a number of problems with the OFT proposals. I recommend that key elements of a reformed UK pharmaceutical environment for 2010 should include an expanded role for HTA but with companies retaining freedom to set prices at launch; HTA use targeted via a contingent value of information approach; a retained backstop PPRS, perhaps moving to an RPI-X type control; the use of risk sharing and non-linear pricing arrangements; measures to ensure more effective therapeutic switching at local level; and measures to improve the take up of cost-effective treatments.

    2011-01-01

    The disparity between the cultural and linguistic diversity of the teaching population and the student population continues to grow as teacher education programs enroll and graduate primarily white teacher candidates (83.7%). At the same time, the diversity of the K-12 student body has increased with 65% of public school students being from culturally and linguistically diverse backgrounds (National Center for Education Statistics, 2007). This chasm between the diversity of the teaching force and student population is of concern as many teachers report that they do not have the cultural knowledge and experience of working or living in diverse environments, yet will be faced with teaching a very diverse student population. Hence, the need for teacher candidates and current teachers to be explicitly taught the skills needed to successfully teach diverse student populations is urgent. In this article, we explore the following phenomena: how linguistic and cultural diversity is regarded in teacher education programs, as well as teacher candidates' and current K-12 teachers' dispositions towards students who do not share their cultural backgrounds or language (including those who vary in their dialects). Finally, we will present strategies that teacher educators can use to embrace and empower culturally and linguistically diverse (CLD) teacher candidates, as well as prepare teacher candidates to teach diverse student populations.

    Christen, Arden G; Christen, Joan A

    2010-01-01

    Cole Porter (1891-1964), an American musical icon, has been internationally acknowledged as one of the most cosmopolitan, sophisticated, elegant and influential composer-lyricists of the 20th century. Born in Indiana and raised in wealth and privilege, he attended both Yale and Harvard universities where he honed his song-writing skills. In his 800 tunes, many of which became smash hits, he blended fresh, witty, urbane and colloquial lyrics with catchy, singable melodies. He composed musical scores for both Broadway stage and Hollywood movies, but focused on the former. While Porter enjoyed penning comic songs, he rarely had them published. In 1946, Cole wrote the music and lyrics for a Broadway show entitled Around the World in Eighty Days. Deemed a failure, it closed after only 75 performances. One light-hearted ditty, "Snagtooth Gertie", which he composed for the show, was never used. The lyrics are presented for the first time in this paper.

    Full Text Available A regression study of Andrade, Krone, McAllister and Hildebrand equations with experimental data of viscosity of mixtures of triglycerides or free fatty acids and trichloroethylene, tetrachloroethylene and hexane was carried out. Temperature range studied was 278-313 K in steps of 5K.
    The results showed that the Hildebrand equation presents the best fit for all the viscosity data of the mixtures studied, tending towards a lineal or parabolic function of its parameters.
    Andrade and Krone equations presented acceptable fits for all mixtures studied except the fatty acids and hexane mixture. The McAllister equation was applicable only to mixtures with tetrachloroethylene.

  12. Just watching the game ain't enough: striatal fMRI reward responses to successes and failures in a video game during active and vicarious playing.

    2013-01-01

    Although the multimodal stimulation provided by modern audiovisual video games is pleasing by itself, the rewarding nature of video game playing depends critically also on the players' active engagement in the gameplay. The extent to which active engagement influences dopaminergic brain reward circuit responses remains unsettled. Here we show that striatal reward circuit responses elicited by successes (wins) and failures (losses) in a video game are stronger during active than vicarious gameplay. Eleven healthy males both played a competitive first-person tank shooter game (active playing) and watched a pre-recorded gameplay video (vicarious playing) while their hemodynamic brain activation was measured with 3-tesla functional magnetic resonance imaging (fMRI). Wins and losses were paired with symmetrical monetary rewards and punishments during active and vicarious playing so that the external reward context remained identical during both conditions. Brain activation was stronger in the orbitomedial prefrontal cortex (omPFC) during winning than losing, both during active and vicarious playing. In contrast, both wins and losses suppressed activations in the midbrain and striatum during active playing; however, the striatal suppression, particularly in the anterior putamen, was more pronounced during loss than win events. Sensorimotor confounds related to joystick movements did not account for the results. Self-ratings indicated losing to be more unpleasant during active than vicarious playing. Our findings demonstrate striatum to be selectively sensitive to self-acquired rewards, in contrast to frontal components of the reward circuit that process both self-acquired and passively received rewards. We propose that the striatal responses to repeated acquisition of rewards that are contingent on game related successes contribute to the motivational pull of video-game playing.

    Mobile technology is very prevalent in Kenya-mobile phone penetration is at 88% and mobile data subscriptions form 99% of all internet subscriptions. While there is great potential for such ubiquitous technology to revolutionise access and quality of healthcare in low-resource settings, there have been few successes at scale. Implementations of electronic health (e-Health) and mobile health (m-Health) technologies in countries like Kenya are yet to tackle human resource constraints or the political, ethical and financial considerations of such technologies. We outline recent innovations that could improve access and quality while considering the costs of healthcare. One is an attempt to create a scalable clinical decision support system by engaging a global network of specialist doctors and reversing some of the damaging effects of medical brain drain. The other efficiently extracts digital information from paper-based records using low-cost and locally produced tools such as rubber stamps to improve adherence to clinical practice guidelines. By bringing down the costs of remote consultations and clinical audit, respectively, these projects offer the potential for clinics in resource-limited settings to deliver high-quality care. This paper makes a case for continued and increased investment in social enterprises that bridge academia, public and private sectors to deliver sustainable and scalable e-Health and m-Health solutions.

  17. The atomic world spooky? It ain't necessarily so! emergent quantum mechanics, how the classical laws of nature can conspire to cause quantum-like behaviour

    CERN Document Server

    van Holten, Theo

    2017-01-01

    The present book takes the discovery that quantum-like behaviour is not solely reserved to atomic particles one step further. If electrons are modelled as vibrating droplets instead of the usually assumed point objects, and if the classical laws of nature are applied, then exactly the same behaviour as in quantum theory is found, quantitatively correct! The world of atoms is strange and quantum mechanics, the theory of this world, is almost magic. Or is it? Tiny droplets of oil bouncing round on a fluid surface can also mimic the world of quantum mechanics. For the layman - for whom the main part of this book is written - this is good news. If the everyday laws of nature can conspire to show up quantum-like phenomena, there is hope to form mental pictures how the atomic world works. The book is almost formula-free, and explains everything by using many sketches and diagrams. The mathematical derivations underlying the main text are kept separate in a -peer reviewed - appendix.

    2016-12-01

    The colonization of a new planet will inevitably bring about new bioethical issues. One is the possibility of pregnancy during the mission. During the journey to the target planet or moon, and for the first couple of years before a colony has been established and the colony has been accommodated for children, a pregnancy would jeopardize the safety of the crew and the wellbeing of the child. The principal concern with a pregnancy during an interplanetary mission is that it could put the entire crew in danger. Resources such as air, food, and medical supplies will be limited and calculated to keep the crew members alive. We explore the bioethical concerns of near-future space travel.

    2013-11-01

    Public sector organisations are facing one of the most difficult financial periods in history and local decision-makers are tasked with making tough rationing decisions. Withdrawing or limiting services is an emotive and complex task and something the National Health Service has always found difficult. Over time, local authorities have gained significant experience in the closure of care homes - an equally complex and controversial issue. Drawing on local knowledge and best practice examples, this article highlights lessons and themes identified by those decommissioning care home services. We believe that such lessons are relevant to those making disinvestment decisions across public sector services, including health-care. The study employed semi-structured interviews with 12 Directors of Adult Social Services who had been highlighted nationally as having extensive experience of home closures. Interviews were conducted over a 2-week period in March 2011. Results from the study found that having local policy guidance that is perceived as fair and reasonable was advocated by those involved in home closures. Many local policies had evolved over time and had often been developed following experiences of home closures (both good and bad). Decisions to close care home services require a combination of strong leadership, clear strategic goals, a fair decision-making process, strong evidence of the need for change and good communication, alongside wider stakeholder engagement and support. The current financial challenge means that public sector organisations need to make tough choices on investment and disinvestment decisions. Any such decisions need to be influenced by what we know constitutes best practice. Sharing lessons and experiences within and between sectors could well inform and develop decision-making practices. © 2013 John Wiley & Sons Ltd.

    2016-07-01

    Teachers are often thought to retire early and have more stress and burnout than other human service professionals. In this article, we investigate attrition intention amongst senior teachers and senior employees of six other blue- and white-collar occupational categories using the Job Demands-Resources (JD-R) model. We followed a two-step approach. First, analysis of variance and logistic regression analysis was used to assess differences in the level of job demands, resources, and attrition intention between occupations for male and female employees separately. Subsequently, multiple group path analysis was used to assess the invariance of the JD-R model across occupational groups and genders. We used representative data gathered in Flanders among 6,810 senior employees (45 years or older). Results indicate that there are differences in the determinants of attrition intention between men and women. The differences in attrition intention are minimal between occupations once controlled for job demands and resources. In addition, the JD-R model is largely invariant across white-collar occupations and gender. We provide support for both the energetic and motivational process of the JD-R model. © The Author(s) 2016.

  9. A nickel ain't worth a dime anymore: the illusion of money and the rapid encoding of its true value.

    Directory of Open Access Journals (Sweden)

    Rongjun Yu

    Full Text Available People often evaluate money based on its face value and overlook its real purchasing power, known as the money illusion. For example, the same 100 Chinese Yuan can buy many more goods in Tibet than in Beijing, but such difference in buying power is usually underestimated. Using event related potential combined with a gambling task, we sought to investigate the encoding of both the real value and the face value of money in the human brain. We found that the self-reported pleasantness of outcomes was modulated by both values. The feedback related negativity (FRN, which peaks around 250ms after feedback and is believed to be generated in the anterior cingulate cortex (ACC, was only modulated by the true value but not the face value of money. We conclude that the real value of money is rapidly encoded in the human brain even when participants exhibit the money illusion at the behavioral level.

    Full Text Available Taounate region is known by a high density of mass movements which cause several human and economic losses. The goal of this paper is to assess the landslide susceptibility of Taounate using the Weight of Evidence method (WofE and the Logistic Regression method (LR. Seven conditioning factors were used in this study: lithology, fault, drainage, slope, elevation, exposure and land use. Over the years, this site and its surroundings have experienced repeated landslides. For this reason, landslide susceptibility mapping is mandatory for risk prevention and land-use management. In this study, we have focused on recent large-scale mass movements. Finally, the ROC curves were established to evaluate the degree of fit of the model and to choose the best landslide susceptibility zonation. A total mass movements location were detected; 50% were randomly selected as input data for the entire process using the Spatial Data Model (SDM and the remaining locations were used for validation purposes. The obtained WofE’s landslide susceptibility map shows that high to very high susceptibility zones contain 62% of the total of inventoried landslides, while the same zones contain only 47% of landslides in the map obtained by the LR method. This landslide susceptibility map obtained is a major contribution to various urban and regional development plans under the Taounate Region National Development Program.

    Evidence-based interventions have been developed and used to prevent HIV infections among black men who have sex with men (MSM) in Canada and the United States; however, the degree to which interventions address racism and other interlocking oppressions that influence HIV vulnerability is not well known. We utilize integrative antiracism to guide a review of HIV prevention intervention studies with black MSM and to determine how racism and religious oppression are addressed in the current intervention evidence base. We searched CINAHL, PsychInfo, MEDLINE and the CDC compendium of evidence-based HIV prevention interventions and identified seventeen interventions. Three interventions targeted black MSM, yet only one intervention addressed racism, religious oppression, cultural assets and religious assets. Most interventions' samples included low numbers of black MSM. More research is needed on interventions that address racism and religious oppression on HIV vulnerability among black MSM. Future research should focus on explicating mechanisms by which multiple oppressions impact HIV vulnerability. We recommend the development and integration of social justice tools for nursing practice that aid in addressing the impacts of racism and other oppressions on HIV vulnerability of black MSM. © 2014 John Wiley & Sons Ltd.

  14. It Ain't the Heat, It's the Humanity: Evidence and Implications of a Knowledge-Based Consensus on Man-Made Global Warming

    Science.gov (United States)

    Jacobs, P.; Cook, J.; Nuccitelli, D. A.

    2013-12-01

    One of the most worrisome misconceptions among the general public about climate change is a belief that scientists disagree not only about the cause of the present climate change, but also whether or not the planet is currently warming. Recent surveys have demonstrated that an overwhelming consensus exists, both within the scientific literature and among scientists with climate expertise, that the planet is warming and humans are driving this climatic change. This disconnect, or 'consensus gap', between scientific agreement and public belief has significant consequences for public understanding of the reality and cause of climate change, as well as support for potential solutions. Ensuring that the consensus message is not simply broadcast but is also accepted as legitimate by the public appears to be a primary education and communications opportunity. While the existence of a consensus is not itself evidence of a position's truth, according to Miller (2013) scientific consensus can be taken as evidence that a position is true if it is 'knowledge-based', satisfying the conditions of social calibration, apparent consilience of evidence, and social diversity. We demonstrate that the scientific consensus on anthropogenic climate change is knowledge-based, satisfying Miller's criteria. In so doing, we hope to increase confidence in its use as an education and communications tool, and assure the public of its validity. We show the consensus is socially calibrated, based on common evidential standards, ontological schemes, and shared formalism. We establish that consilience of evidence points overwhelmingly to the reality of anthropogenic climate change by examining the evidence from several perspectives. We identify unique fingerprints expected as a result of increased greenhouse forcing, eliminate potential natural drivers of climate change as the cause of the present change, and demonstrate the consistency of the observed climate response with known changes in natural and manmade forcings across a wide variety of indices. Finally, we determine that the consensus is socially diverse, being geographically and disciplinarily varied, supported within public and private institutions, and endorsed by research organizations as well as groups with obvious financial incentives to deny it, such as fossil fuel companies. Additionally, we briefly discuss examples of purported incorrect consensus in climate research, and detail how they fail to satisfy one or more aspects of Miller's criteria. We conclude by discussing the key role that knowledge-based consensus can potentially play in education, influencing public beliefs about climate change, and increasing support for solutions.

    Full Text Available Los pacientes con alteraciones de la hemostasia constituyen un grupo de riesgo en la atención estomatológica cuando tienen que ser sometidos a procederes que presuponen sangramiento. La hemostasia está determinada por una serie de eventos complejos que evitan que se pierda sangre del torrente circulatorio, y la falla de cualquiera de estos mecanismos provocará salida de sangre de los vasos sanguíneos, máxime si el proceder estomatológico que se va a aplicar conlleva sangramiento de tejidos. Por tal motivo se debe solicitar un estudio del caso antes de proceder, con el fin de diagnosticar qué tipo de trastorno presenta el paciente e indicar tratamiento específico en su caso. Es propósito de este trabajo incursionar en aquellos trastornos de la hemostasia que involucran a las plaquetas y alargan el tiempo de sangramiento, así como abordar las deficiencias de factores de la coagulación que afectan este importante mecanismo; por otro lado, dada su importancia, abarcaremos los efectos antiinflamatorios no esteroideos (AINES y anticoagulantes en pacientes que necesitan un tratamiento quirúrgico estomatológico, de manera que se facilite la labor del profesional de la salud que a diario se enfrenta con problemas de esta índole y dotarlo de un conocimiento valioso en cada uno de los aspectos tratados.Patients with hemostatic disorders are a risk group in dental care when they should undergo dental procedures that presupposes bleeding.

    2016-01-01

    The functions of dance and music in human evolution are a mystery. Current research on the evolution of music has mainly focused on its melodic attribute which would have evolved alongside (proto-)language. Instead, we propose an alternative conceptual framework which focuses on the co-evolution of rhythm and dance (R&D) as intertwined aspects of a multimodal phenomenon characterized by the unity of action and perception. Reviewing the current literature from this viewpoint we propose the hypothesis that R&D have co-evolved long before other musical attributes and (proto-)language. Our view is supported by increasing experimental evidence particularly in infants and children: beat is perceived and anticipated already by newborns and rhythm perception depends on body movement. Infants and toddlers spontaneously move to a rhythm irrespective of their cultural background. The impulse to dance may have been prepared by the susceptibility of infants to be soothed by rocking. Conceivable evolutionary functions of R&D include sexual attraction and transmission of mating signals. Social functions include bonding, synchronization of many individuals, appeasement of hostile individuals, and pre- and extra-verbal communication enabling embodied individual and collective memorizing. In many cultures R&D are used for entering trance, a base for shamanism and early religions. Individual benefits of R&D include improvement of body coordination, as well as painkilling, anti-depressive, and anti-boredom effects. Rhythm most likely paved the way for human speech as supported by studies confirming the overlaps between cognitive and neural resources recruited for language and rhythm. In addition, dance encompasses visual and gestural communication. In future studies attention should be paid to which attribute of music is focused on and that the close mutual relation between R&D is taken into account. The possible evolutionary functions of dance deserve more attention.

    Full Text Available The functions of dance and music in human evolution are a mystery.

Our view is supported by increasing experimental evidence particularly in infants and children: beat is perceived and anticipated already by newborns and rhythm perception depends on body movement.

    Full Text Available La trombosis es una de las causas de muerte más importante en los países industrializados. La trombosis arterial es responsable del infarto de miocardio y de los accidentes cerebrovasculares y se genera en zonas de daño arterial. Los antiplaquetarios y anticoagulantes desempeñan un papel fundamental en la prevención y tratamiento. La enfermedad tromboembólica venosa, a través de la trombosis venosa profunda y la embolia pulmonar, es la tercera causa de muerte después de los eventos arteriales. Ésta suele tratarse con anticoagulantes. En este trabajo se revisan los nuevos fármacos antiplaquetarios y anticoagulantes y su impacto en la cirugía cardiovascular.

    To study and characterise the MR imaging findings of lesions of the anterior interosseous nerve (AIN). Magnetic resonance imaging (MRI) findings of the forearm of ten patients referred to our institution with suspected AIN lesions were retrospectively studied. Five healthy volunteers with normal forearm MRI findings formed a control group. Two musculoskeletal radiologists assessed the forearm musculature for oedema in the distribution of the AIN, median, posterior interosseous and radial nerves on T2-weighted (T2W) fat-saturated sequences. T1-weighted (T1W) images were assessed and graded for the presence of muscle atrophy and fatty involution. Six patients had undergone surgical exploration; five of these had surgically confirmed AIN compression. Four patients had diagnoses other than AIN compression made on imaging features. Of the cases of proven AIN compression, oedema within the pronator quadratus (PQ) muscle was identified in all cases. PQ atrophy and fatty involution were seen in three (43%) surgically confirmed cases. Cases 2 and 3 also demonstrated oedema in the flexor digitorum profundus (FDP)1 and FDP2 muscles. These cases also showed oedema in the flexor-carpi radialis (FCR) and FDP3/FDP4 muscles, respectively. The four cases of non-AIN compression demonstrated muscle oedema patterns that were atypical for the AIN distribution. They included a rupture of the flexor pollicis longus (FPL) tendon, brachial neuritis, amyotrophic lateral sclerosis and compression of the proximal median nerve. MRI is a useful investigation in the diagnostic workup of AIN syndrome. AIN syndrome is likely when there is diffuse oedema of AIN innervated muscles on T2W fat-saturated images. The most reliable sign of an AIN lesion is oedema within the PQ. Oedema in the flexor carpi radialis, FDP3 and FDP4, although not in the classical distribution of the AIN, does not preclude the diagnosis of AIN syndrome. (orig.)

    2009-11-01

    Acute interstitial nephritis (AIN) secondary to trimethoprim-sulfamethoxazole (TMP-SMX) is well documented as a cause of acute renal failure in native kidneys. TMP-SMX is the standard prophylactic agent against pneumocystis carinii (PCP) used in the early post-transplant period, however, it has to date only been indirectly associated with AIN in renal allografts. DESIGN, SETTING, PARTICIPANTS AND MEASUREMENTS: We describe eleven renal transplant patients with acute allograft dysfunction in whom a transplant biopsy demonstrated primary histopathologic features of allergic AIN, all of whom were receiving TMP-SMX in addition to other medications known to cause AIN.

  7. Kinetics and thermodynamics of cottonseed oil extraction

    Directory of Open Access Journals (Sweden)

    Saxena, Devesh K.

    2011-06-01

    Full Text Available Petroleum derived n-hexane is commercially used in solvent extraction plants due to its higher extraction efficiency in spite of the fact that it is graded as highly toxic and hazardous. The present study is based on the use of both a much safer and non toxic solvent ethanol and n-hexane for the extraction of oil from cottonseed. The extraction data were obtained by varying temperature, solvent-solid ratio and particle size, to compare the extraction efficiency of both ethanol and n-hexane. The data show that nearly the same amount of extraction is possible at a higher solvent-solid ratio for both the solvents. This study has established that the kinetics of oil extraction follows a second order reaction mechanism. The thermodynamic analysis of the data shows that both ΔHº and ΔSº are positive, and ΔGº is negative indicating that the extraction process is endothermic, irreversible, and spontaneous.

    El n-hexano derivado del petróleo es comercialmente usado en plantas de extracción con disolventes debido a su mayor eficiencia de extracción, a pesar de que está calificado como altamente tóxico y peligroso. El presente estudio está basado en el uso de etanol, disolvente mucho más seguros y no tóxico, y n-hexano en la extracción de aceite de algodón. Los datos de extracción fueron obtenidos variando la temperatura, la proporción sólido-disolvente y el tamaño de partícula, para comparar la eficiencia de extracción del etanol y del hexano. Los datos muestran que casi la misma cantidad de extracción es posible para ambos disolventes a la proporción más alta de sólido-disolvente. Este estudio es capaz de establecer que las cinéticas de extracción de aceite siguen un mecanismo de reacción de segundo orden. El análisis termodinámico de los datos mostró que ΔHº and ΔSº son positivas, y ΔGº es negativa, indicando que el proceso de extracción es endotérmico, irreversible y espontáneo.

El objetivo es investigar si factores ambientales como algunas exposiciones profesionales (trabajo nocturno, manejo de disolventes y/o campos electromagnéticos incrementan la probabilidad de trastornos del espectro autista (TEA en los hijos. Métodos: Estudio observacional de casos y controles mediante análisis de expedientes de 206 niños entre 16 y 36 meses de edad evaluados en el Servicio de Atención Temprana de Ciudad Real (70 con TEA y 136 no afectados. Para medir el riesgo de TEA asociado al trabajo nocturno, con disolventes y/o campos electromagnéticos se calculó la odds ratio (OR con un intervalo de confianza (IC del 95%. Resultados: El riesgo de TEA se multiplica por 2,22 cuando un progenitor trabaja en las ocupaciones estudiadas (OR=2,22, IC 95%=1,42-3,48, destacando trabajo con disolventes (OR=2,81, IC 95%=1,28-6,17 y nocturno (OR=2,18, IC 95%=1,21-3,93.

Destacam-se as potencialidades da utilização da etnografia na pesquisa avaliativa de sistemas e serviços de saúde.This paper analyzes the results of an evaluative study in the city of Manaus, Amazonas State, Brazil, on primary health care for patients with hypertension and/or diabetes. The ethnographic approach used access to services and comprehensiveness of health care as core analytical categories, comparing the health practices developed by Family Health Program (FHP units with traditional non-FHP primary care units. Access to family health care units in low-income communities is limited by the precarious surrounding urban infrastructure. The main barrier to access to primary care units is distance. The lack of a referral system between the various levels of complexity jeopardizes patients' access to tests and specialists. The care supplied by the two units is limited to patient conditions that can be treated pharmacologically, thus compromising the comprehensiveness of care. The health professionals display a limited capacity to hear problems outside the immediate focus of the program activity. The paper highlights the potential for using ethnography in evaluative research on health systems and services.

    SUMMARY Quorum sensing, a group behavior coordinated by a diffusible pheromone signal and a cognate receptor, is typical of bacteria that form symbioses with plants and animals. LuxIR-type acyl homoserine-lactone (AHL) quorum sensing is common in Gram-negative proteobacteria, and many members of this group have additional quorum-sensing networks. The bioluminescent symbiont Vibrio fischeri encodes two AHL signal synthases: AinS and LuxI. AinS-dependent quorum sensing converges with LuxI-dependent quorum sensing at the LuxR regulatory element. Both AinS- and LuxI-mediated signaling are required for efficient and persistent colonization of the squid host, Euprymna scolopes. The basis of the mutualism is symbiont bioluminescence, which is regulated by both LuxI- and AinS-dependent quorum sensing, and is essential for maintaining a colonization of the host. Here, we used chemical and genetic approaches to probe the dynamics of LuxI- and AinS-mediated regulation of bioluminescence during symbiosis. We demonstrate that both native AHLs and non-native AHL analogs can be used to non-invasively and specifically modulate induction of symbiotic bioluminescence via LuxI-dependent quorum sensing. Our data suggest that the first day of colonization, during which symbiont bioluminescence is induced by LuxIR, is a critical period that determines the stability of the V. fischeri population once symbiosis is established.

  18. Allergic Interstitial Nephritis Manifesting as a Striated Nephrogram

    2015-01-01

    Full Text Available Allergic interstitial nephritis (AIN is an underdiagnosed cause of acute kidney injury (AKI. Guidelines suggest that AIN should be suspected in a patient who presents with an elevated serum creatinine and a urinalysis that shows white cells, white cell casts, or eosinophiluria. Drug-induced AIN is suspected if AKI is temporally related to the initiation of a new drug. However, patients with bland sediment and normal urinalysis can also have AIN. Currently, a definitive diagnosis of AIN is made by renal biopsy which is invasive and fraught with risks such as bleeding, infection, and hematoma. Additionally, it is frequently unclear when a kidney biopsy should be undertaken. We describe a biopsy proven case of allergic interstitial nephritis which manifested on contrast enhanced Magnetic Resonance Imaging (MRI as a striated nephrogram. Newer and more stable macrocyclic gadolinium contrast agents have a well-demonstrated safety profile. Additionally, in the presentation of AKI, gadolinium contrast agents are safe to administer in patients who demonstrate good urine output and a downtrending creatinine. We propose that the differential for a striated nephrogram may include AIN. In cases in which the suspicion for AIN is high, this diagnostic consideration may be further characterized by contrast enhanced MRI.

    Undergraduate nurses are employed as assistants in nursing (AIN) in inpatient mental health settings; however, there is a paucity of published research exploring registered nurses' (RN) views about the AIN role in these settings. This qualitative study documents the views and experiences of RN working with undergraduate AIN. Fifty structured face-to-face interviews were analysed, and the results are discussed in three sections. The first section outlines RN perceptions of qualities and skills required of AIN in mental health, and the responses primarily focus on communication skills, initiative, and willingness to learn. The second section targets factors in the workplace that might enhance the interest of AIN in a mental health nursing career; the responses emphasize their need to work with experienced staff. The last section outlines RN expectations of AIN, most of which are met and involve physical observations and technical tasks; less fulfilled activities primarily cluster around interactions with patients. Findings highlight the advantages and disadvantages of drawing on undergraduate nursing students as AIN in mental health settings. Communication skills, personal initiative, safety training to prevent violence, and education to increase knowledge and awareness about mental illness, diagnosis, and mental status-related skills were all important concerns articulated by RN. © 2011 The Authors.

  20. Metal nitride coatings by physical vapor deposition (PVD) for a wear resistant aluminum extrusion die.

    Lee, Su Young; Kim, Sang Ho

    2014-12-01

    The purpose of this study is to investigate the friction and wear behaviors of CrN, TiN, CrAlN, and TiAIN coated onto SKD61 for application to Al 7000 series extrusion dies. On the wear test, the experimental parameters are the load and the counter material's temperature. The results showed that the friction coefficient increased with load but decreased with the counter material's temperature, and the friction coefficients of CrN and CrAIN were lower than the friction coefficients of TiAIN and TIN, especially at a higher temperature. The wear track with different coatings identified different wear behaviors; the wear behavior of CrAIN was found to be abrasive, but the wear behavior of TiN, CrN, and TiAIN was adhesive. Therefore, CrAIN showed the least wear loss with a lower friction coefficient and less adhesion with counter materials at the highest range of wear load and temperature. This resulted in the easy formation of aluminum oxide in the wear track and less Al adhesion; moreover during the hard second phase, AIN dispersed in the film during deposition.

    This paper deals with the hydrogeology and isotopic composition of water samples collected from selected spring in sinai (e.g. Algudierate, Alqusiema, qidis and Isram) in order to identify their genesis, their interaction with the host rocks and mixing trend. Results of isotopic composition have indicated the similarity in the hydrogeologic situation of Ain qidis and Ain-al-gudierate, while Ain Isram has shown a marked difference in its stable isotope and this could be due to evaporation effect. The isotopic and hydrochemical constituents of the studied springs reflect eater of a meteoric origin with a possible contamination from surficial materials (evaporates) and deeper aquifers. 6 figs., 2 tabs.

    Full Text Available Spent nickel catalyst (SNC have the potential of insulting the quality of the environment in a number of ways. The disposal of SNC will have a pollution effect. Optimum recovery of fat from SNC , could save the environment and reduce the oil loss. Hexane has been the solvent of choice for oil extraction. Alternative solvents that are considered safer have been evaluated. Hexane, isopropanol, ethanol, and heptane were examined using soxhlet extraction. While hexane was more efficient in oil recovery from SNC, isopropanol proved to be very good, to clarifying separation of oil from waste material and also provide high solvent recovery compared to other solvents. Isopropanol extraction with chill provided separation of miscella into two phases: lower oil–rich and an upper solvent – rich. It saved much energy of vaporization for distilling. An aqueous extraction process with immiscible solvent assisted was tested. Solvent like hexane added to SNC, and water added later with continuous stirring. The mixture was stirred for about 30 minutes, prior to centrifugation. Aqueous process extracted less amount of oil compared to solvent extraction.El catalizador agotado de níquel (SNC tiene el potencial de dañar la calidad del medio ambiente de diversas formas. El depósito de SNC tendrá un efecto de polución. La recuperación óptima de la grasa a partir del SCN, podría conservar el medio ambiente y reducir la pérdida de aceite. El hexano ha sido el disolvente elegido para la extracción del aceite. También se han evaluado disolventes alternativos que son considerados seguros. Se han examinado hexano, isopropanol, etanol y heptano usando extracción con soxhlet. Mientras que el hexano fue el mas eficaz en la recuperación del aceite, el isopropanol demostró ser muy bueno para aclarar la separación del aceite a partir de la materia residual y también proporcionó una alta recuperación del disolvente en comparación con los otros

    Formation processes of Aluminum nitride (AIN) in Aluminum (AI) implanted with nitrogen were examined by in situ EELS and TEM observations during nitrogen ion implantation in an electron microscope at room temperature and 400 deg C. AIN phase was identified both by EDP and EELS after nitrogen ion implantation to 6 x 10 20 (N + )/m 2 . The observed peak (20.8 eV) in EELS spectra was identified as plasmon loss peak of AIN formed in AI. The binding energy of N ls in AI was found to shift by about 4 eV to the lower side with increasing nitrogen-ion fluence. Unreacted AI was also found to remain in the AIN films after high fluence implantation both at room temperature and 400 deg C. (authors). 11 refs., 5 figs., 2 tabs

    2012-02-01

    BACKGROUND: Anal intraepithelial neoplasia (AIN) rarely receives as much publicity as its neighbouring orifice, the cervix. As in the cervix, intraepithelial neoplasias are precursors to cancer in the anal canal. AIN and cervical interstitial neoplasia (CIN) undergo dysplasia as a consequence of human papillomavirus (HPV) infection. Since the advent of screening with the Pap smear in CIN, cervical cancer has plummeted to a fifth of its initial incidence. Anal cancer, however, has been rising, with a predilection for human immunodeficiency virus-infected men. HPV causes a squamous epithelial dysplasia and converts healthy tissue into AINs of increasing severity until anal cancer manifests. CLINICAL CASE: This article describes a clinical case of anogenital HPV infection refractory to medical and surgical therapy. It also describes an effective surgical excision technique associated with a good cosmetic outcome. CONCLUSIONS: The paper concludes by briefly discussing the implications of a national screening programme against AIN in the future.

    Acute interstitial nephritis (AIN) is a common cause of acute kidney injury and is characterised by a dense interstitial cellular infiltrate, which has not been well defined. Previous studies have demonstrated a correlation between Epstein-Barr virus (EBV) infection and AIN. The purpose of our study was to define the nature of the interstitial immune infiltrate and to investigate the possibility of renal infection with EBV.

    2018-04-01

    The increasing worldwide incidence of colon cancer has been linked to obesity and consumption of a high-fat Western diet. To test the hypothesis that a high-fat diet (HFD) promotes colonic aberrant crypt (AC) formation in a manner associated with gut bacterial dysbiosis, we examined the susceptibility to azoxymethane (AOM)-induced colonic AC and microbiome composition in C57/BL6 mice fed a modified AIN93G diet (AIN, 16% fat, energy) or an HFD (45% fat, energy) for 14 weeks. Mice receiving the HFD exhibited increased plasma leptin, body weight, body fat composition and inflammatory cell infiltration in the ileum compared with those in the AIN group. Consistent with the gut inflammatory phenotype, we observed an increase in colonic AC, plasma interleukin-6, tumor necrosis factor-α, monocyte chemoattractant protein-1 and inducible nitric oxide synthase in the ileum of the HFD-AOM group compared with the AIN-AOM group. Although the HFD and AIN groups did not differ in bacterial species number, the HFD and AIN diets resulted in different bacterial community structures in the colon. The abundance of certain short-chain fatty acid (SCFA) producing bacteria (e.g., Barnesiella) and fecal SCFA (e.g., acetic acid) content were lower in the HFD-AOM group compared with the AIN and AIN-AOM groups. Furthermore, we identified a high abundance of Anaeroplasma bacteria, an opportunistic pathogen in the HFD-AOM group. Collectively, we demonstrate that an HFD promotes AC formation concurrent with an increase of opportunistic pathogenic bacteria in the colon of C57BL/6 mice. Published by Elsevier Inc.

  10. Acute interstitial nephritis with acetaminophen and alcohol intoxication

    Directory of Open Access Journals (Sweden)

    Alexopoulou Iakovina

    2011-04-01

    Full Text Available Abstract Drug-induced acute interstitial nephritis (AIN represents a growing cause of renal failure in current medical practice. While antimicrobials and non-steroidal anti-inflammatory drugs are typically associated with drug-induced AIN, few reports have been made on the involvement of other analgesics. We report our experience in managing a 17-year-old female with AIN and subsequent renal injury following an acetaminophen overdose in conjunction with acute alcohol intoxication. It is well established that acetaminophen metabolism, particularly at high doses, produces reactive metabolites that may induce renal and hepatic toxicity. It is also plausible however, that such reactive species could instead alter renal peptide immunogenicity, thereby inducing AIN. In the following report, we review a possible mechanism for the acetaminophen-induced AIN observed in our patient and also discuss the potential involvement of acute alcohol ingestion in disease onset. The objective of our report is to increase awareness of healthcare professionals to the potential involvement of these commonly used agents in AIN pathogenesis.

However, progress of the AIN deployment has been slow due to the many barriers that exist in the traditional wireline carriers' deployment procedures and infrastructure. The success of AIN has not been truly demonstrated. The AIN objectives and directions are applicable to the wireless industry although the plans and implementations could be significantly different. This paper points out WIN characteristics in architecture, flexibility, deployment, and value to customers. In order to succeed, the technology driven AIN concept has to be reinforced by the market driven WIN services. An infrastructure suitable for the WIN will contain elements that are foreign to the wireline network. The deployment process is expected to seed with the revenue generated services. Standardization will be achieved by simplifying and incorporating the IS-41C, AIN, and Intelligent Network CS-1 recommendations. Integration of the existing and future systems impose the biggest challenge of all. Service creation has to be complemented with service deployment process which heavily impact the carriers' infrastructure. WIN deployment will likely start from an Intelligent Peripheral, a Service Control Point and migrate to a Service Node when sufficient triggers are implemented in the mobile switch for distributed call control. The struggle to move forward will not be based on technology, but rather on the impact to existing infrastructure.

    Research Highlights: → Human papillomaviruses cause anal intraepithelial neoplasia (AIN). → Digital image processing was carried out to classify the grades of AIN quantitatively. → The fractal dimension as well as grey value statistics was calculated. → Higher grades of AIN yielded higher values of the fractal dimension. → An automatic detection system is feasible. - Abstract: It is well known that human papillomaviruses (HPV) induce a variety of tumorous lesions of the skin. HPV-subtypes also cause premalignant lesions which are termed anal intraepithelial neoplasia (AIN). The clinical classification of AIN is of growing interest in clinical practice, due to increasing HPV infection rates throughout human population. The common classification approach is based on subjective inspections of histological slices of anal tissues with all the drawbacks of depending on the status and individual variances of the trained pathologists. Therefore, a nonlinear quantitative classification method including the calculation of the fractal dimension and first order as well as second order image statistical parameters was developed. The absolute values of these quantitative parameters reflected the distinct grades of AIN very well. The quantitative approach has the potential to decrease classification errors significantly and it could be used as a widely applied screening technique.

    Nitriding of surface of aluminum alloys was carried out with using an electron-beam-excited-plasma (EBEP)technique. The EBEP is sustained by electron impact ionization with energetic electron beam. Two kinds of substrates,aluminum alloys AA5052 and AA5083, were exposed to the down flow of EBEP source at 843 K for 45min. The specimens were characterized with respect to following properties: crystallographic structure (XRD), morphology (SEM) and the cross sectional microstructures of the nitrided layer was observed using a scanning electron microscopy (SEM). There are some Al2O3 particles on the surface of the nitrided AA5052 and AA5083. The AIN layers were formed on the substrates with the thickness of 4.5 μ m for AA5052 and 0.5 μ m for AA5083. A relatively uniform nitrided surface layer composed of AIN can be observed on the AA5052 substrate. The grains size near the interfaces between the substrate and AIN layer were smaller than that near the surface. On the surface of AIN layer, the concentration of nitrogen was high and in the middle of AIN layer it had a constant concentration like the aluminum and the concentration was decreased with approaching to the interface. On the surface of nitrided AA5083, a uniform AIN layer was not formed as the reason for the high nitriding temperature.

    Full Text Available The olive foot cake is a very important by-product of olive oil industry since it can contain until 12 % of oil which can be extracted using solvent. The used solvent is often immiscible with water. This is the reason why its effect is limited by the moisture of olive foot cake making its drying imperative. In this paper, we present the behaviour of olive foot cake subjected to convective drying. The experimental results show that the drying rate versus moisture presents only one period of decreasing rate. The influence of the main parameters on drying kinetics is studied.El orujo es un importante subproducto de la industria del aceite de oliva ya que puede contener hasta el 12 % del aceite, el cual puede ser extraído usando un disolvente apropiado. El uso del disolvente es a menudo inmiscible con el agua. Esta es la razón por la que su efecto está limitado por la humedad del orujo, haciendo su secado imperativo. En este artículo se presenta el comportamiento del orujo sometido a un secado por convección. Los resultados experimentales mostraron que la velocidad de secado frente a la humedad, presenta un solo período de disminución de dicha velocidad. Se ha estudiado la influencia de los principales parámetros sobre la cinética de secado.

    Full Text Available En estos últimos años, principalmente en los Estados Unidos, ha surgido una gran variedad de equipos portátiles para el examen rápido de suelos, basados la mayor parte en reacciones calorimétricas para fósforo, potasio, nitratos y algunos otros elementos considerados de importancia para la vida de la planta. El factor que determina la gran variedad de resultados obtenidos con tales equipos es la naturaleza del disolvente empleado para extraer los elementos de la muestra de suelo, disolvente que consiste, por lo general en soluciones de distinta concentración de ácido clorhídrico, sulfúrico, acético. etc. Si se admite que estos exámenes rápidos en el campo pueden ser útiles en países donde los agricultores cuentan con grandes facilidades para hacer verificar análisis completes de sus tierras, con mayor razón debemos admitir que en nuestro país, donde no abundan los laboratorios especializados, los equipos portátiles son casi una necesidad para la orientación de los agrónomos oficiales que operan en regiones apartadas. Debido a esto, la Facultad Nacional de Agronomía se ha interesado en el desarrollo de un equipo portátil lo más compacto posible para el uso de los agrónomos.

    Full Text Available In this work the quality of grape seed oil obtained by extraction with supercritical carbon dioxide was studied. At the optimun operating conditions (313 K and 25 MPa, the yield of supercritical extraction is similar to the conventional extraction by liquid solvent, but the quality of the grape seed oil extracted by supercritical carbon dioxide is higher.
    Furthermore, supercritical extraction could be more economical than liquid extraction because the solvent removal by distillation is not necessary and several steps of the subsequent oil refining process can be eliminated.

    As the aluminium nitrides play an important role in the manufacturing of steel sheets, a specific methodology was developed based on the thermoelectric power (TEP) technique, in order to determine the AIN nitrogen by an indirect method. The free nitrogen was determined and then the AIN nitrogen was calculated by the difference between the total nitrogen and the free nitrogen. Indeed, it is easier to determine the dissolved nitrogen, the content of which gradually decreases during the AIN precipitation, than the AIN nitrogen. A low carbon aluminium killed steel was employed with 580 ppm of aluminium and 50 ppm of nitrogen. A comparison of the results obtained by TEP with those obtained by other techniques (hot hydrogen extraction, electrochemical dissolution followed by a mineralization, electrochemical dissolution followed by a sodic decomposition and the Beeghly method) was conducted, in order to determine a reliable technique likely to quantify the amount of aluminium nitrides in aluminium killed steels. With these techniques, it is possible to determine either free nitrogen or precipitated nitrogen. From an experimental point of view, the precipitation kinetics of AIN was followed during an annealing performed at 973 K (700 C) by TEP and then different precipitation states of AIN were investigated to compare the different techniques: three annealing states (when no nitrogen, half the nitrogen and the total nitrogen has precipitated) and two soaking states (1403 and 1523 K). Thus, it was possible to compare states where the AIN precipitates are in various forms (different shapes, crystallographic structures, sizes, distributions in the matrix). This work showed that the quantification by TEP, hot hydrogen extraction and electrochemical dissolution followed by a mineralization seem reliable whereas the Beeghly method gives good results only for the precipitates formed at high temperatures. In contrast, the quantification by electrochemical dissolution followed by

    Highlights: • Electropolymerization of 5-aminoindole (AIn) in the presence of graphene (GE). • Significant catalytic effect of GE on the polymerization of AIn. • PAIn/GE/GC used as Pt catalyst support. • The enhanced catalytic activity of Pt/PAIn/GE/GC for methanol electrooxidation. -- Abstract: 5-Aminoindole (AIn) was electropolymerized on graphene (GE) modified glass carbon (GC) electrode in 0.5 M H 2 SO 4 aqueous solution containing 0.01 M AIn. Because of the catalytic effect of GE, the polymerization efficiency of AIn and the electrochemical activity of as-formed poly(5-aminoindole) (PAIn) were significantly improved on GE/GC electrode as compared to that on the bare GC electrode. The prepared PAIn/GE/GC electrode was used as substrate for Pt particle electrodeposition. SEM, EDX and Raman spectral were used to characterize the prepared electrodes. Electrocatalytic experiments demonstrate that the Pt/PAIn/GE/GC electrode possesses high catalytic activity toward methanol electrooxidation in alkaline medium, due to the good dispersion of Pt particles on PAIn/GE/GC and the electronic interactions between the metal particles and the polymer matrixes. Thus, PAIn can be a promising alternative for polymeric catalyst support in direct alcohol fuel cells

    Full Text Available Resumen Introducción: La heparina es el fármaco anticoagulante de elección y de uso habitual en los servicios de hemodiálisis, en el procedimiento de permeabilización de los catéteres venosos centrales, aunque su uso no está exento de riesgos como la hemorragia. La infección asociada al catéter, bien por colonización del catéter o por bacteriemia, es el evento más importante y la segunda causa de mortalidad tras la enfermedad cardiovascular en el paciente en hemodiálisis. En este sentido, el uso del citrato se está presentando como una alternativa para el sellado de los catéteres venosos centrales, dado que tiene propiedades tanto anticoagulantes locales como antimicrobianas y podría ser más eficiente en la prevención o la reducción de la infección asociada al catéter. Objetivos: Identificar qué anticoagulante de uso en el sellado del catéter venoso central, la heparina o el citrato, presenta menos complicaciones de bacteriemia asociada al catéter y de colonización del catéter; Material y Método: se realizó una búsqueda bibliográfica a través del metabuscador EBSCOhost (Academic Search Premier, CINAHL y las bases de datos PubMed, IME, Ibecs, LILACS, CUIDEN, Scopus y Cochrane Library, con la selección final de 15 documentos tras la aplicación de los límites de búsqueda, la eliminación de duplicados y la aplicación de los criterios de inclusión/exclusión.

Despite the clear conservation and molecular significance, it is unknown if miRISC-GW182 interaction is essential for gene silencing during animal development. Using Caenorhabditis elegans to explore this question, we examined the relationship and effect on gene silencing between the GW182 orthologs, AIN-1 and AIN-2, and the microRNA-specific Argonaute, ALG-1. Homology modeling based on human Argonaute structures indicated that ALG-1 possesses conserved Tryptophan-binding Pockets required for GW182 binding. We show in vitro and in vivo that their mutations severely altered the association with AIN-1 and AIN-2. ALG-1 tryptophan-binding pockets mutant animals retained microRNA-binding and processing ability, but were deficient in reporter silencing activity. Interestingly, the ALG-1 tryptophan-binding pockets mutant phenocopied the loss of alg-1 in worms during larval stages, yet was sufficient to rescue embryonic lethality, indicating the dispensability of AINs association with the miRISC at this developmental stage. The dispensability of AINs in miRNA regulation is further demonstrated by the capacity of ALG-1 tryptophan-binding pockets mutant to regulate a target of the embryonic mir-35 microRNA family. Thus, our results demonstrate that the microRNA pathway can act independently of GW182 proteins during C. elegans embryogenesis.

    Objective The aim of the current study was to evaluate secretory leukocyte protease inhibitor (SLPI) expression in anal biopsies from HIV-positive (HIV+) individuals, and compare that to anal intraepithelial neoplasia (AIN) diagnoses and human papillomavirus (HPV) status. Design This is a cross-sectional study of a cohort of 54 HIV+ (31 males and 23 females) from an AIDS clinic in Rio de Janeiro, Brazil. Methods The study material consisted of anorectal tissue biopsies obtained from HIV+ subjects, which were used to construct tissue microarray paraffin blocks for immunohistochemical analysis of SLPI expression. Biopsies were evaluated by an expert pathologist and classified as low-grade anal intraepithelial neoplasia (AIN1), high-grade anal intraepithelial neoplasia (AIN2/3), or normal squamous epithelium. Additionally, DNA from the biopsies was extracted and analyzed for the presence of low- or high-risk HPV DNA. Results Histologically normal squamous epithelium from the anorectal region showed strong positive SLPI staining in 17/20 (85%) samples. In comparison, 9/17 (53%) dysplastic squamous epithelial samples from AIN1 patients showed strong SLPI staining, and only 5/17 (29%) samples from AIN2-3 patients exhibited strong SPLI staining, which both were significantly fewer than those from normal tissue (p=0.005). Furthermore, there was a significantly higher proportion of samples in which oncogenic high-risk HPV genotypes were detected in low SLPI expressing tissues than that in tissues with high SLPI expression (p=0.040). Conclusion Taken together these results suggest that low SLPI expression is associated with high-risk HPV infections in the development of AIN. PMID:27149102

    Full Text Available Piperazine as an antihelminth has many adverse effects, especially on patients with renal insufficiency. We report the use of piperazine in a girl with a moderately severe kidney disease due to Biedl Bardet syndrome. She developed coma and acute kidney injury due to acute interstitial nephritis (AIN, anemia and thrombocytopenia. The presence of fever, proteinuria, acidosis, anemia, sterile pyuria and non-oliguric renal failure strongly suggested AIN. Her problems abated mostly by discontinuing of piperazine and supportive therapy, except anemia and thrombocytopenia.

    We report the case of severe colitis occurring during treatment with non-steroid anti-inflammatories (NSAI). A 57 year-old woman was hospitalized for lumbar pain that had not been relieved by AINS, tramadol and then morphine. The patient presented with septic shock and peritonitis by rectal perforation, followed by acute rectorrhagia. The endoscopic aspect evoked Crohn's disease with a recto-vaginal fistula. Progression was further complicated by two episodes of collapse because of acute rectorrhagia, requiring hemostasis colectomy and abdominal-perineal amputation. The diagnosis retained was AINS-induced colitis complicated by acute colectasia on a fecaloma with recto-vaginal fistula.

    In the present study, the supercritical carbon dioxide (Co2) extraction of oil from Simarouba gluaca seeds was carried out at varying conditions of pressure (300–500 bar), temperature (50–70 °C) and CO2 flow rate (10–30 g·min-1). The extraction condition for maximum oil yield was obtained at 500 bar pressure, 70 °C and at 30 g·min-1 flow rate of CO2. The extracted oil was analyzed thoroughly for physico-chemical properties and compared with those of conventional solvent extracted oil. An interesting observation is a significant reduction in the phosphorus content of the oil (8.4 mg·kg-1) extracted using supercritical CO2 compared to the phosphorous content of the solvent extracted oil (97 mg·kg-1). Moreover, the content of total tocopherols in supercritically extracted oil (135.6 mg·kg-1) was found to be higher than the solvent extracted oil (111 mg·kg-1). The rest of the physico-chemical properties of the two differently extracted oils matched well with each other. The results indicated the possible benefits of supercritical CO2 extraction over solvent extraction of Simarouba gluaca seed oil. [Spanish] En el presente estudio se llevó a cabo la extracción con dióxido de carbono supercrítico (CO2) de aceites de semillas de Simarouba gluaca en diversas condiciones de presión (300–500 bar), temperatura (50–70 °C) y el caudal de CO2 (10–30 g·min-1). La condición de extracción para obtener el máximo rendimiento de aceite se obtuvo a una presión de 500 bares, una temperatura de 70 °C y un caudal de CO2 de 30 g·min-1. Al aceite extraido se determinó sus propiedades fisicoquímicas y se comparó con las del aceite extraído con disolvente convencional. Una observación interesante es la reducción significativa del contenido de fósforo (8,4 mg·kg-1) del aceite extraído utilizando CO2 supercrítico en comparación con el del aceite extraído con disolvente (97 mg·kg-1). Además, el contenido de tocoferol total en el aceite extra

Se estimó la CL50 de cada uno de los extractos, mediante bioensayos con la técnica de película residual, sobre adultos de mosquita blanca. Además, se evaluó el efecto repelente a partir de la CL50 de cada extracto, se estimó el índice de repelencia (IR, si IR = 1 el efecto es neutro, IR 1, el efecto es atrayente. Los extractos de hoja-etanol, hoja-agua y hoja-acetona presentaron valores menores de CL50 700, 1,190 y 1,250 ppm respectivamente, lo que indica alta eficiencia sobre B. tabaci, seguidos del extracto tallo-agua, por último los extractos tallo-etanol y tallo-acetona presentaron menor efectividad. Todos los extractos tuvieron acción repelente, independientemente del disolvente y órgano de la planta a 24 y 48 h. Sin embargo, los extractos a base de agua podrían tener mayor potencial para el control de la mosquita blanca en sistemas de manejo integrado de plagas, debido a que presentaron efecto insecticida y repelente, además el disolvente es inocuo y de bajo costo.

    Anal cancer is an increasing issue in HIV-positive men who have sex with men (MSM). Screening for its precursor, anal intraepithelial neoplasia (AIN), is subject of discussion. Current treatment options are suboptimum and have not been compared in a prospective trial. We compared efficacy and side-effects of imiquimod, topical fluorouracil, and electrocautery for the treatment of AIN. In this open-label randomised trial, we included HIV-positive MSM older than 18 years visiting the HIV outpatient clinic of the Academic Medical Center, Amsterdam, Netherlands. Patients with histologically confirmed AIN were randomly assigned to receive either 16 weeks of imiquimod (three times a week), 16 weeks of topical fluorouracil (twice a week), or monthly electrocautery for 4 months. Randomisation was done with random block sizes of three and six, stratified for AIN grade (AIN grades 1, 2, or 3) and AIN location (peri-anal or intra-anal). Participants were assessed by high-resolution anoscopy 4 weeks after treatment. Responding patients returned for follow-up 24 weeks, 48 weeks, and 72 weeks after treatment. The primary endpoint was histological resolution of AIN measured 4 weeks after treatment and AIN recurrence at week 24, week 48, and week 72 after treatment. The primary analysis was done in a modified intention-to-treat population, including all patients who had received their assigned treatment at least once. The trial is registered at the Netherlands Trial Register, number NTR1236. Between Aug 12, 2008, and Dec 1, 2010, we screened 388 HIV-positive MSM for AIN by high resolution anoscopy. Of the 246 (63%) patients who had AIN, 156 (63%) were randomly assigned to either receive imiquimod (54 patients), topical fluorouracil (48 patients), or electrocautery (46 patients) following withdrawing of consent by eight patients. Modified intention-to-treat analysis showed a complete response in 13 (24%, 95% CI 15-37) patients in the imiquimod group, eight (17%, 8-30) of patients
