[A_Ribera_SanEsteban] Modelo virtual de la iglesia de San Esteban de Ribera de Valderejo (Álava)

[ES] Ribera es un pueblo abandonado dentro del parque natural de Valderejo, el único edificio que queda en pie es la antigua iglesia. La razón por la que este edificio no fue derribado es la presencia de un conjunto de pinturas murales de época medieval. Por lo demás, el edificio (de unos 25 x 12 metros en planta) se encontraba en un mal estado de conservación (de hecho, un par de años más tarde de la realización de este trabajo se derrumbó la sacristía).

Germinación de semillas de especies adaptadas a un medio extremófilo: Río Tinto

Se presentan los porcentajes de germinación de 12 especies representativas de la vegetación de ribera y matorral del ecosistema del río Tinto en diferentes condiciones de pH (5,4; 3,2; 1,8 y agua del río Tinto). Se observan distintas respuestas de germinación en las especies estudiadas, encontrando los mayores porcentajes de germinación en Nerium oleander y Salicornia ramosissima. Dada la respuesta positiva de estas dos especies, se discute su utilidad para la restauración de los territorios afectados en los alrededores del río Tinto. Para el resto de especies, se observan bajos porcentajes de germinación y en la mayoría de las especies analizadas el pH no influye en la germinación. Hay muchos factores que limitan la germinación de las semillas tales como la latencia que requiere de un pre-tratamiento (de frío o de calor), variación en las condiciones naturales que son difíciles de recrear en el laboratorio o la baja calidad de las semillas.

Arte en Quintana del Pidio (Burgos): estudio histórico-artístico de la iglesia de Santiago Apóstol

La parroquia de Santiago Apóstol de Quintana del Pidio, situada en la ribera burgalesa, se levanta en la plaza mayor de la citada localidad, junto al ayuntamiento. Esta construcción tardogótica de finales de la Edad Media se fue completando con una torre de comienzos del siglo XVI, una portada y una sacristía barrocas y una única capilla dedicada al Santo Cristo, edificada ya en el siglo XVIII. En su interior se conservan cinco retablos barrocos que ejemplifican las fases clasicista, churrigueresca y rococó. También cuenta con pinturas, un interesante ajuar de platería y otros objetos de mobiliario, ornamentos o indumentaria que han sido estudiados en el libro. La metodología histórico-artística empleada en este trabajo permite entender la obra en su contexto, completando su significado con una lectura iconográfica cuando procede. Con la catalogación y la aportación de datos sobre las artes de esta parroquia ribereña se pretenden poner el valor las obras que desde la segunda mitad del siglo XV han ido completando el patrimonio artístico de esta villa para que se adquiera conciencia de su importancia y se dediquen los recursos necesarios para su conservación en el futuro.

Uptake and factors that influence the use of 'sit less, move more' occupational intervention strategies in Spanish office employees

Background: Little is known about the types of 'sit less, move more' strategies that appeal to office employees, or what factors influence their use. This study assessed the uptake of strategies in Spanish university office employees engaged in an intervention, and those factors that enabled or limited strategy uptake. Methods: The study used a mixed method design. Semi-structured interviews were conducted with academics and administrators (n = 12; 44 +/- 12 mean SD age; 6 women) at three points across the five-month intervention, and data used to identify factors that influenced the uptake of strategies. Employees who finished the intervention then completed a survey rating (n = 88; 42 +/- 8 mean SD age; 51 women) the extent to which strategies were used [never (1) to usually (4)]; additional survey items (generated from interviewee data) rated the impact of factors that enabled or limited strategy uptake [no influence (1) to very strong influence (4)]. Survey score distributions and averages were calculated and findings triangulated with interview data. Results: Relative to baseline, 67% of the sample increased step counts post intervention (n = 59); 60% decreased occupational sitting (n = 53). 'Active work tasks' and 'increases in walking intensity' were the strategies most frequently used by employees (89% and 94% sometimes or usually utilised these strategies); 'walk-talk meetings' and ` lunchtime walking groups' were the least used (80% and 96% hardly ever or never utilised these strategies). 'Sitting time and step count logging' was the most important enabler of behaviour change (mean survey score of 3.1 +/- 0.8); interviewees highlighted the motivational value of being able to view logged data through visual graphics in a dedicated website, and gain feedback on progress against set goals. 'Screen based work' (mean survey score of 3.2 +/- 0.8) was the most significant barrier limiting the uptake of strategies. Inherent time pressures and cultural norms that dictated sedentary work practices limited the adoption of 'walk-talk meetings' and ` lunch time walking groups'. Conclusions: The findings provide practical insights into which strategies and influences practitioners need to target to maximise the impact of 'sit less, move more' occupational intervention strategies.

The patents in the introduction of reinforced concrete in Spain: "Alhondiga de Bilbao" case study

Reinforced concrete structures are introduced in Spain mainly by French influence. This happens in the late nineteenth century, following the scheme operating through proprietary systems prevailing in Europe. Systems initially have poor scientific support reaching, even early twentieth century, an impediment to the development of concrete structures, due to the lack of knowledge shown, as well as due to a series of accidents. Therefore, from the end of the first decade of the past century are enacted a series of regulations in many countries, that will change the design and calculation of reinforced concrete structure. The knowledge of the environment of the patent systems, its beginnings and the circumstances of their application allow us to understand the constraints of the early concrete structures, as presented in the Bilbao wine store (1906).

Patterns of Impact Resulting from a 'Sit Less, Move More' Web-Based Program in Sedentary Office Employees

Purpose Encouraging office workers to 'sit less and move more' encompasses two public health priorities. However, there is little evidence on the effectiveness of workplace interventions for reducing sitting, even less about the longer term effects of such interventions and still less on dual-focused interventions. This study assessed the short and mid-term impacts of a workplace web-based intervention (Walk@WorkSpain, W@WS; 2010-11) on self-reported sitting time, step counts and physical risk factors (waist circumference, BMI, blood pressure) for chronic disease. Methods Employees at six Spanish university campuses (n=264; 42 +/- 10 years; 171 female) were randomly assigned by worksite and campus to an Intervention (used W@WS; n=129; 87 female) or a Comparison group (maintained normal behavior; n=135; 84 female). This phased, 19-week program aimed to decrease occupational sitting time through increased incidental movement and short walks. A linear mixed model assessed changes in outcome measures between the baseline, ramping (8 weeks), maintenance (11 weeks) and follow-up (two months) phases for Intervention versus Comparison groups. Results A significant 2 (group) x 2 (program phases) interaction was found for self-reported occupational sitting (F[3]=7.97, p=0.046), daily step counts (F[3]=15.68, p=0.0013) and waist circumference (F[3]=11.67, p=0.0086). The Intervention group decreased minutes of daily occupational sitting while also increasing step counts from baseline (446 +/- 126; 8,862 +/- 2,475) through ramping (+425 +/- 120; 9,345 +/- 2,435), maintenance (+422 +/- 123; 9,638 +/- 3,131) and follow-up (+414 +/- 129; 9,786 +/- 3,205). In the Comparison group, compared to baseline (404 +/- 106), sitting time remained unchanged through ramping and maintenance, but decreased at follow-up (-388 +/- 120), while step counts diminished across all phases. The Intervention group significantly reduced waist circumference by 2.1cms from baseline to follow-up while the Comparison group reduced waist circumference by 1.3cms over the same period. Conclusions W@WSis a feasible and effective evidence-based intervention that can be successfully deployed with sedentary employees to elicit sustained changes on "sitting less and moving more".

Self-reported sitting time and physical activity: interactive associations with mental well-being and productivity in office employees

Background: Little is known about how sitting time, alone or in combination with markers of physical activity (PA), influences mental well-being and work productivity. Given the need to develop workplace PA interventions that target employees' health related efficiency outcomes; this study examined the associations between self-reported sitting time, PA, mental well-being and work productivity in office employees. Methods: Descriptive cross-sectional study. Spanish university office employees (n = 557) completed a survey measuring socio-demographics, total and domain specific (work and travel) self-reported sitting time, PA (International Physical Activity Questionnaire short version), mental well-being (Warwick-Edinburg Mental Well-Being Scale) and work productivity (Work Limitations Questionnaire). Multivariate linear regression analyses determined associations between the main variables adjusted for gender, age, body mass index and occupation. PA levels (low, moderate and high) were introduced into the model to examine interactive associations. Results: Higher volumes of PA were related to higher mental well-being, work productivity and spending less time sitting at work, throughout the working day and travelling during the week, including the weekends (p < 0.05). Greater levels of sitting during weekends was associated with lower mental well-being (p < 0.05). Similarly, more sitting while travelling at weekends was linked to lower work productivity (p < 0.05). In highly active employees, higher sitting times on work days and occupational sitting were associated with decreased mental well-being (p < 0.05). Higher sitting times while travelling on weekend days was also linked to lower work productivity in the highly active (p < 0.05). No significant associations were observed in low active employees. Conclusions: Employees' PA levels exerts different influences on the associations between sitting time, mental well-being and work productivity. The specific associations and the broad sweep of evidence in the current study suggest that workplace PA strategies to improve the mental well-being and productivity of all employees should focus on reducing sitting time alongside efforts to increase PA.
