Underway physical oceanography and carbonate chemistry measured during the EURO-BASIN cruise M87/1 (Deep Convection Cruise)

The track of the cruise, and the location of the different stations cover a large range of water masses, many of which take part in the exchange across the Greenland-Scotland Ridge, and of importance for the biogeochemical fluxes in the region. These water masses are of very different origins, which can be observed in the concentration of the different biogeochemical parameters. The concentrations are a result of the combination of the physical and biogeochemical environment in each formation region, and the processes acting on the water masses as they are transported away from the formation areas. The aim of the biogeochemistry measurements was to achieve a better understanding of the strength and variability of the biological carbon pump in the North Atlantic and Nordic Seas.

Physical parameters in relation to physiological changes of avocado during ripening (20ºc) and cold storage (6ºc) in different conditions.

The application of the response of fruits to low energy for mechanical impacts is described, for evaluation of post-harvest ripening of avocadoes of the variety "Hass". An impactor of 50g of weight, provided with an accelerometer, and free-falling from a height of 4 cm, is used; it is interfaced to a computer and uses a special software for retrieving and analyzing the deceleration data. Impact response parameters of individual fruits were compared to firmness of the pulp, measured by the most used method of double-plate puncture, as well as to other physical and physiological parameters: color, skin puncture ethylene production rate and others. Two groups of fruits were carefully selected, stored at 6º C (60 days) and ripened at 20ºC (11 days), and tested during the storage period. It is shown that, as in other types of fruits, impact response can be a good predictor of firmness in avocadoes, obtaining the same accuracy as with destructive firmness measurements. Mathematical and multiple regression models are calculated and compared to measured data, with which a prediction of storage period can be made for these fruits.

Viviendas productivas

El presente trabajo recoge los resultados de una investigación sobre la «vivienda productiva», es decir, de la casa como lugar de trabajo. Dicha investigación se ha ocupado de explorar cómo influyen las cotidianeidades doméstico-laborales actuales —junto con sus arquitecturas y los urbanismos que estas generan— en la sociedad, en especial en temas sociales centrales como la construcción de las subjetividades, y de una vida en comunidad. Asimismo, explora cómo podrían influir en un futuro. La hipótesis sobre la que se trabaja, y que finalmente se intenta demostrar, consiste en que, en la territorialidad múltiple de lo laboral, la vivienda, como plataforma doméstica multiusos, productiva y reproductiva de la que muchas personas disponen, desempeña un papel nodal, y es posible que en el futuro su papel sea aún más importante y más visible. La vivienda productiva funciona como una infraestructura urbana desde la cual se construyen diferentes tipos de bienes materiales e inmateriales, pero sobre todo formas de relación, sociales y productivas con otros, además de imaginarios y afectos. La vivienda como infraestructura productiva y reproductiva es tanto «fábrica fundamental de lo social», como nos enseña Silvia Federici, como «fábrica de lo urbano». El trabajo en casa, como parte de diferentes dinámicas «dispersas» del trabajo que se dan en la actualidad, presenta tanto problemáticas y desafíos importantes, como capitales y posibilidades sociales. Por un lado, puede facilitar una absorción de tipo «24/7» vinculada a las lógicas de producción dispersa y consumo dominantes además de la que se da por las dinámicas patriarcales tradicionales, y en múltiples casos situaciones de evidente asimetría y de explotación laboral. También puede propiciar situaciones socialmente extendidas o impuestas de soledad y aislamiento. Sin embargo, está asimismo vinculado al surgimiento de espacios de experimentación tanto en soledad como en compañía, de cooperación y de intercambio, además de a la evidente posibilidad de construir rutinas propias y, por tanto, una subjetividad laboral propia. Por otro lado, frente a la idea general y homogénea del trabajador casero como un sujeto mayoritariamente aislado de su entorno, las jornadas de trabajo de los trabajadores caseros estudiados presentan una gran diversidad. Estas pueden conllevar aislamiento y exclusión, así como acompañar diferentes formas de construcción de una ciudadanía activa, tanto en solitario, como mediante formas de participación activa en la construcción de una vida en comunidad. En esta investigación se analizan, pues, desafíos y oportunidades de estas espacialidades del trabajo y, a través de este análisis, se indaga en el papel de los marcos físicos, organizativos y simbólicos actuales para la vivienda y para la ciudad pensada desde los trabajadores caseros. Al mismo tiempo se exploran nuevos tipos de vivienda y urbanismos que puedan quizás acompañar procesos sociales de inclusión, así como de emancipación, cooperación e intercambio y, en general, nuevas formas de vecindad y bienestar compartido en los ámbitos doméstico-productivos. Metodológicamente, las singularidades presentes en las realidades estudiadas invitan además a explorar protocolos de análisis, métodos de diseño, de gestión y gobierno que, desde lo micro, puedan dialogar con lo cotidiano y sus singularidades. Diego Barajas, autor de la tesis, es arquitecto dedicado a la práctica, a la investigación y la docencia. Su trabajo se focaliza en explorar el carácter mediador de la arquitectura frente a lo cotidiano y sus microrrealidades. Es profesor de proyectos de urbanismo en la IE School of Architecture y es miembro de Husos, una plataforma de investigación y diseño orientada a la innovación en arquitectura y urbanismo, con sede en Madrid.

ABSTRACT The present study records an investigation into the «productive house», or the home as a workplace. This investigation looks at how working from home, its architectures, and the urban dynamics generated around it influence daily life and the construction of society. It also explores what influences home-based work might have in the future, particularly in central themes such as the biopolitical construction of subjectivities and community life. The central hypothesis revolves around the idea that the home, as a multi-use infrastructure that most of us have access to, plays a fundamental role in the contemporary work sphere, due to —or even in spite of— the omnipresence of work in practically every moment and area of our daily lives, and might play a main role in the future. The home functions as a kind of hub from which we create different kinds of material and immaterial goods, but above all relationships with others, both social and productive, as well as imaginaries and affections. The home, as a machine for production and reproduction, is as much a main «factory of the social» as Silvia Federici describes it, as a «factory of the urban». Working from home, as one of several «dispersed» work dynamics that are part of the contemporary world of work, presents as many important problematics and challenges as it does possibilities and social capital. On the one hand, it can contribute to kind of «24/7» absorption linked both to the logistics of the current dispersed production and consumption, and to that of traditional patriarchal dynamics, and in some cases even clearly asymmetrical situations that exploit the workforce. It can also lead to the socially widespread phenomena of isolation and loneliness, at times imposed upon home-based workers. However, by the same token, it is also linked to the growth of experimental spaces of cooperation and exchange, both solitary and in company, as well as the clear possibility of constructing individualised routines and, therefore, a personal laboural subjectivity. On the other hand, contrary to the generalised, homogenous idea of a home-based worker who is mostly isolated from his or her environment, the working days of those we studied went hand in hand with different ways of building subjectivities. This could be as much in exclusion and isolation as through building an active citizenship, at times in solitary and at times actively participating in the construction of communal life. In this investigation, therefore, the challenges and opportunities of the home as workplace have been analysed, and through this analysis we have inquired into the role of current physical, organisational and symbolic frameworks for the home and for the city from the perspective of home workers. At the same time we have explored new types of homes and of town planning that could perhaps accompany social processes of diversity and inclusion as well as emancipation, cooperation and exchange and, in general, new forms of shared welfare in productive domestic environments. Methodologically, the singularities present in the cases studied also invite us to explore protocols of analysis, methods of design, management and government that, from the micro level, could dialogue with the peculiarities of day-to-day life. The author of this thesis, Diego Barajas, is an architect dedicated to practice, investigation and teaching. His work is focussed on exploring the mediating nature of architecture and the built environment in terms of daily life and its microrealities.

Efficient high-resolution genetic mapping of mouse interspersed repetitive sequence PCR products, toward integrated genetic and physical mapping of the mouse genome.

The ability to carry out high-resolution genetic mapping at high throughput in the mouse is a critical rate-limiting step in the generation of genetically anchored contigs in physical mapping projects and the mapping of genetic loci for complex traits. To address this need, we have developed an efficient, high-resolution, large-scale genome mapping system. This system is based on the identification of polymorphic DNA sites between mouse strains by using interspersed repetitive sequence (IRS) PCR. Individual cloned IRS PCR products are hybridized to a DNA array of IRS PCR products derived from the DNA of individual mice segregating DNA sequences from the two parent strains. Since gel electrophoresis is not required, large numbers of samples can be genotyped in parallel. By using this approach, we have mapped > 450 polymorphic probes with filters containing the DNA of up to 517 backcross mice, potentially allowing resolution of 0.14 centimorgan. This approach also carries the potential for a high degree of efficiency in the integration of physical and genetic maps, since pooled DNAs representing libraries of yeast artificial chromosomes or other physical representations of the mouse genome can be addressed by hybridization of filter representations of the IRS PCR products of such libraries.

What can physical, biotic and chemical features of a tree hollow tell us about their associated diversity?

Tree hollows are keystone structures for saproxylic fauna and host numerous endangered species. However, not all tree hollows are equal. Many variables including physical, biotic and chemical ones, can characterise a tree hollow, however, the information that these could provide about the saproxylic diversity they harbour has been poorly explored. We studied the beetle assemblages of 111 Quercus species tree hollows in four protected areas of the Iberian Peninsula. Three physical variables related to tree hollow structure, and two biotic ones (presence of Cetoniidae and Cerambyx species recognised as ecosystem engineers) were measured in each hollow to explore their relative effect on beetle assemblages. Moreover, we analysed the chemical composition of the wood mould in 34 of the hollows, in order to relate beetle diversity with hollow quality. All the environmental variables analysed (physical and biological) showed a significant influence on saproxylic beetle assemblages that varied depending on the species. Furthermore, the presence of ecosystem engineers affected both physical and chemical features. Although wood mould volume, and both biotic variables could act as beetle diversity surrogate, we enhance the presence of Cetoniidae and Cerambyx activity (both easily observable in the field) as indicator variables, even more if both co-occur as each affect to different assemblages. Finally, assimilable carbon and phosphorous contents could act as indicator for past and present beetle activity inside the cavity that could become a useful tool in functional diversity studies. However, an extension of this work to other taxonomic groups would be desirable.

Structured Sports and Physical Activities: Their Critical Role

Even though one recognizes the physical and psychological kindness of h more and more involvement of the children to the physical and sporty activities, these programs seem more and more inaccessible to some. This article underlines the importance school déprogrammes centered on structured physical and sporty activities. In the setting of a recent survey, one asked youngsters to 5th year to take in note all their activities (as diary calendar) during two days of consecutive week. L·s children that participated in structured physical and sporty activities before and after the hours class sembkient to pull a lot more phisir of their day that those that didn't participate in these activities. Besides, seuk the young that took to structured physical and sporty activities reached the rates recommended of daily physical activity. The article proposes to the school administrators, to the parents, to the children and to the collectivities various measures encouraging the adoption of additional programs centered on the physical and sporty activities in school environment.

Physical Characteristics and Estimated Hydraulic Conductivity from Grain-Size Distribution for Vashon Till, South-Central Puget Lowland, Washington

Population growth, urban development, and increased commercial and industrial activity in the south-central Puget Lowlands of Washington State has led to an increased demand for groundwater. The Vashon till is a glacially consolidated, low-permeability unit comprising unstratified clay, silt, cobbles and boulders with ubiquitous coarse-grained lenses and is an extensive surficial unit throughout the south-central Puget Lowland. Thus, understanding the physical and hydrological characteristics – specifically, the hydraulic conductivity – of this unit is a necessary component of a groundwater model. This study provides (1) a record of the physical characteristics of Vashon till deposits within the study area; and (2) an estimate of the highest, lowest, and average value of saturated hydraulic conductivity based on the grain-size distribution of Vashon till samples collected from six field sites in the Puyallup River Watershed. Analysis shows that the average moisture content ranges between about 1 and 6%, average dry bulk density is about 2.20 g/cm3, and average porosity is about 17%. Grain-size distributions show that half of the samples analyzed are well graded, while the other half is poorly graded. Grain-size distributions also show an average d10 value of about 0.20 mm, and average ff values ≤ 16%, which are key values in estimating the saturated hydraulic conductivity of over-consolidated glacial deposits. Based on these observed values, the estimates of hydraulic conductivity range from a minimum of 0.02 m/d to a maximum of 1.38 m/d in within the general Vashon till.

Play behaviours and play object preferences of young children with autistic disorder in a clinical play environment

Play is the primary occupation of childhood and provides a potentially powerful means of assessing and treating children with autistic disorder. This study utilized a cross-sectional comparison design to investigate the nature of play engagement in children with AD (n = 24), relative to typically developing children (n = 34) matched for chronological age. Play behaviours were recorded in a clinical play environment. Videotapes comprising 15 minutes of the children's spontaneous play behaviour were analysed using time-interval analysis. The particular play behaviours observed and play objects used were coded. Differences in play behaviours (p < 0.0001) and play object preferences (p < 0.0001) were identified between the groups. Findings regarding play behaviour contribute to contention in the literature surrounding functional and symbolic play. Explanations for play object preferences are postulated. Recommendations are made regarding clinical application of findings in terms of enhancing assessment and intervention by augmenting motivation.

Betwixt spaces: student accounts of turning point experiences in first year transitions

‘Not belonging’ is becoming a prevalent theme within accounts of the first-year student experience at university. In this study the notion of not belonging is extended by assuming a more active role for the idea of liminality in a student’s transition into the university environments of academic and student life. In doing so, the article suggests that the transition between one place (home) and another (university) can result in an ‘in-between-ness’ – a betwixt space. Through an interpretative methodology, the study explores how students begin to move from this betwixt space into feeling like fully-fledged members of university life. It is concluded that there is a wide range of turning points associated with the students’ betwixt transition, which shapes, alters or indeed accentuates the ways in which they make meaningful connections with university life. Moreover, transitional turning point experiences reveal a cast of characters and symbolic objects; capture contrasting motivations and evolving relationships; display multiple trajectories of interpersonal tensions and conflicts; highlight discontinuities as well as continuities; and together, simultaneously liberate and constrain the students’ transition into university life.

Global and physical self-esteem and body dissatisfaction as mediators of the relationship between weight status and being a victim of bullying

Research has found evidence of a link between being overweight or obese and bullying/peer victimisation, and also between obesity and adjustment problems such as low self-esteem and body dissatisfaction. Studies have also found that adjustment problems can put children at an increased risk of being bullied over time. However, to date the factors that place overweight or obese children at risk of being bullied have been poorly elucidated. Self-report data were collected from a sample of 11-14 year olds (N=376) about their weight status, about their experiences of three different types of bullying (Verbal, Physical and Social), their global self-worth, self-esteem for physical appearance, and body dissatisfaction. Overweight or obese children reported experiencing significantly more verbal and physical (but not social) bullying than their non-overweight peers. Global self-worth, self-esteem for physical appearance and body dissatisfaction each fully mediated the paths between weight status and being a victim of bullying.

The effect of bioglass addition on mechanical and physical properties of photoactive UDMA-TEGDMA resin composites

Light curable dimethacrylate resin composites undergo free radical photopolymerisation in response to blue light (wavelength 450-500 nm) and may offer superior handling and setting characteristics for novel hard tissue repair materials. The current investigation aims to determine the optimum formulation of bisphenol-A glycidyl methacrylate and triethyleneglycoldimethacrylate (bisGMA/TEGDMA) or urethane dimethacrylate (UDMA)/TEGDMA resin mixtures and the effect of Bioglass incorporation on the rate of polymerisation (RP), degree of conversion (DC) and flexural strength (FS) of light-curable filled resin composites (FRCs). Experimental photoactive resins containing a range of bisGMA, UDMA and TEGDMA ratios and/or filled with non-silanised irregular or spherical 45S5-Bioglass (50 μm; 5-40 wt%) and/or silanised silicate glass filler particulates (0.7 μm; 50-70 wt%) were tested. RP and DC were analysed in real-time using nearinfrared spectroscopy. FS of resins and FRCs were determined using three-point flexural strength tests. UDMA/TEGDMA resins exhibited increased DC compared with bisGMA/TEGDMA resins (p<0.05). The addition of spherical particles of Bioglass had a detrimental effect on the FS (p>0.05), whereas they increased DC of UDMA/TEGDMA resins (p<0.05). Addition of irregular shaped Bioglass particles increased the FS of UDMA/TEGDMA resins up to 20 wt% Bioglass (p<0.05). The flexibility and strength conferred by the urethane group in UDMA may result in enhanced physical and mechanical properties compared with conventional resins containing bulky (bisGMA) molecules. Addition of 45S5-Bioglass with specific filler content, size and morphology resulted in enhanced mechanical and physical properties of UDMA/TEGDMA composites. © (2014) Trans Tech Publications, Switzerland.
