Prevalence of human papillomavirus in the saliva of sexually active women with cervical intraepithelial neoplasias

The main objective of this study was to estimate the prevalence of human papillomavirus-DNA (HPV-DNA) in the saliva of sexually active women with HPV-related cervical intraepithelial neoplasias (CIN) and compare the findings with a healthy control group. The secondary objectives were: 1) to determine the concordance between genital and oral HPV types in sexually active women with HPV-related CIN; 2) to analyze whether sexual habits influence the presence of HPV-related CIN; 3) to determine whether sexual habits influence the presence of oral HPV. Saliva samples were collected from 100 sexually active women, 50 with HPV-related CIN and 50 healthy subjects presenting normal cytology. PCR assay was used to detect HPV-DNA. The prevalence of oral HPV infection in saliva samples was 14% in women with HPV-related CIN, while in the healthy group it was 12%, without statistically significant difference (p =0.766). As for the concordance between genital and oral HPV types in women with HPV-related CIN, concordance was only observed for HPV-16, whereby among 22 women with genital HPV-16, only one (4.54%) also presented oral HPV-16. Regarding the possible influence of sexual habits on the presence of cervical pathology and presence of oral HPV, it was found that marital status, age at first intercourse, number of lifetime sexual partners, and condom use are related with the presence of cervical pathology (p<0.001; p=0.017; p=0.002; and p <0.001, respectively); condom use was also found to be related to the presence of oral HPV (p<0.001). The prevalence of HPV-DNA in the saliva of sexually active women with HPV-related CIN is similar to healthy women. The concordance between genital and oral HPV types is low. Both the presence of cervical pathology and the presence of oral HPV are related to sexual habits. Wider sample size is required to confirm this results

Thirteenth Intercomparison Campaign of the Regional Brewer Calibration Center Europe: Lichtklimatisches Observatorium, Arosa, Switzerland: 30 July–10 August 2018

Editado por Alberto Redondas y Stoyka NetchevaThis thirteenth campaign was a joint exercise of the Regional Brewer Calibration Center for Europe (RBCC-E) and the Regional Dobson Calibration Center (RDCC-E) with the support of MeteoSwiss and of the Global Atmosphere Watch (GAW) Programme of the World Meteorological Organization (WMO). The following operations were performed by the RBCC-E during the intercomparison: Ozone calibration against the RBCC-E travelling reference (B#185) ; Compilation of the calibration histories of the instruments ; Evaluation of the Level 2 Eubrewnet ozone data for the period between intercomparisons

La degradación y el mantenimiento en las obras de edificación: estudio de caso Institución Educativa Antonio Derka Santo Domingo

El presente trabajo de investigación tiene por objeto identificar y describir los efectos de deterioro que se manifiestan en una edificación específica, describiendo cuál debe ser el control de la edificación como tal, planteando un proceso adecuado para el mantenimiento y haciendo un diagnóstico de los diferentes deterioros y daños, que se deben a la falta de planificación de actividades de conservación y cuidado de estás. Por esto se requiere del diseño y ejecución de un manual de mantenimiento que contenga pautas claras y de control para alargar la vida útil de la edificación, basado en el Manual de Uso Conservación y Mantenimiento de los Colegios de la Secretaría de Educación de Bogotá con el Formato de Inspección de Infraestructura, el cual consiste en un levantamiento, realizado durante el estudio, de los aspectos físicos que conforman cada ambiente o área de la sede.This research work aims to identify and describe the effects of deterioration that occur in a specific building, describing what should be the control of the building as such, recommending an appropiate process for doing maintenance and doing a diagnosis of different impairments and damages, which are due to poor planning and conservation activities. That’s why it needs the design and implementation of a maintenance manual containing clear guidelines to control and extend the life of the building, based on the instruction manual Conservation and Maintenance of Schools of the Ministry of Education in Bogota Infrastructure Inspection of construction, which consists of a survey, conducted during the study of the physical aspects of the school

Fourteenth Intercomparison Campaign of the Regional Brewer Calibration Centre Europe : El Arenosillo Atmospheric Sounding Station, Huelva, Spain, 17-28 June 2019

In this campaign, the Regional Brewer Calibration Center for Europe (RBCC-E) transferred its own absolute ozone calibration obtained from the Langley method at the Izaña Observatory to all other participating instruments. Such intercomparison campaigns, with a large number of participating instruments, provide an overview of the current state of ozone measurements being made by the European Brewer network. The instruments were compared with the RBCC-E standard Brewer#185 for ozone and with the European reference standard from the World Radiation Center (WRC) QASUME unit for UV

Twelfth Intercomparison Campaign of the Regional Brewer Calibration Center Europe: El Arenosillo Atmospheric Sounding Station, Huelva, Spain, 29 May to 9 June 2017

Editado por Alberto Redondas y Stoyka NetchevaThe twelfth European Brewer Intercomparison Campaign was organized by the Regional Brewer Calibration Center for Europe (RBCC-E) in collaboration with the “Area of Instrumentation and Atmospheric Research Area” of Instituto Nacional de Tecnica Aeroespacial (INTA), with the support of the Global Atmosphere Watch (GAW) Programme of the World Meteorological Organization (WMO) and the EUBREWNET ES1207 COST Action. Alongside the campaign, the ATMOZ (Traceability of Atmospheric Total Ozone) project workshop took place at the station. In addition, this event was also used as a demonstration exercise of the calibration methodologies and error assessment developed by the project (Gröbner et al., 2018)

Internal consistency of the Regional Brewer Calibration Centre for Europe triad during the period 2005–2016

Total ozone column measurements can be made using Brewer spectrophotometers, which are calibrated periodically in intercomparison campaigns with respect to a reference instrument. In 2003, the Regional Brewer Calibration Centre for Europe (RBCC-E) was established at the Izaña Atmospheric Research Center (Canary Islands, Spain), and since 2011 the RBCC-E has transferred its calibration based on the Langley method using travelling standard(s) that are wholly and independently calibrated at Izaña. This work is focused on reporting the consistency of the measurements of the RBCC-E triad (Brewer instruments #157, #183 and #185) made at the Izaña Atmospheric Observatory during the period 2005–2016. In order to study the long-term precision of the RBCC-E triad, it must be taken into account that each Brewer takes a large number of measurements every day and, hence, it becomes necessary to calculate a representative value of all of them. This value was calculated from two different methods previously used to study the long-term behaviour of the world reference triad (Toronto triad) and Arosa triad. Applying their procedures to the data from the RBCC-E triad allows the comparison of the three instruments. In daily averages, applying the procedure used for the world reference triad, the RBCC-E triad presents a relative standard deviation equal to σ = 0.41%, which is calculated as the mean of the individual values for each Brewer (σ157 = 0.362%, σ183 = 0.453% and σ185 = 0.428%). Alternatively, using the procedure used to analyse the Arosa triad, the RBCC-E presents a relative standard deviation of about σ = 0.5%. In monthly averages, the method used for the data from the world reference triad gives a relative standard deviation mean equal to σ = 0.3% (σ157 = 0.33%, σ183 = 0.34% and σ185 = 0.23%). However, the procedure of the Arosa triad gives monthly values of σ = 0.5%. In this work, two ozone data sets are analysed: the first includes all the ozone measurements available, while the second only includes the simultaneous measurements of all three instruments. Furthermore, this paper also describes the Langley method used to determine the extraterrestrial constant (ETC) for the RBCC-E triad, the necessary first step toward accurate ozone calculation. Finally, the short-term or intraday consistency is also studied to identify the effect of the solar zenith angle on the precision of the RBCC-E triad.This work has been supported by the European Metrology Research Programme (EMRP) within the joint research project ENV59 “Traceability for atmospheric total column ozone” (ATMOZ)
