As part of a systemic assessment toward social sustainability of egg production, we have reviewed current knowledge about the environmental impacts of egg production systems and identified topics requiring further research. Currently, we know that 1) high-rise cage houses generally have poorer air quality and emit more ammonia than manure belt (MB) cage houses; 2) manure removal frequency in MB...

Eco -friendly architectural principles are being incorporated into more buildings every day in the world but they are still out of reach of many people due to lack of knowledge and awareness. Nevertheless, many traditional societies learned to build collaborating with nature, basing their buildings on an intuitive knowledge of the environment and climate, constructing buildings at a very low co...

OBJECTS We carried out an investigation to clarify the real state of indoor air pollution by chlorpyrifos (termiticide) and exposure to chlorpyrifos of residents by measuring its urinary metabolite 3,5,6-trichloro-2-pyridinol (TCP) as an exposure index, such as biological monitoring. METHODS The investigation was conducted in 43 individual houses with termiticide application (whether the term...

The basic urban tissue of medieval European cities consisted brick townhouses. In the northern Europe, these tenements were characterised by a block based on an elongated rectangular plan, covered with gable roof ridge oriented perpendicularly to street. side walls tenement house common for both neighbours and constituted structural element. façades not loaded ceilings, providing freedom in sha...

Composite samples of freshly voided excreta from 91 poultry houses were tested qualitatively for Salmonella; 26 (29%) were positive. The houses were located on 36 farms, 18 of which (50%) yielded one or more positive samples. In a separate, quantitative study, Salmonella densities ranged from less than 1 to over 34,000 per g of excreta (dry weight). High densities were noted in waste from cage ...

Housing allocation problems deal with assigning indivisible objects (houses) to agents who have preferences over these objects. We examine the housing allocation problem with existing tenants, then with both new and existing tenants. In both cases, we present and evaluate an algorithm for assigning houses. We then consider a version of the housing allocation problem where agents are grouped int...

OBJECTIVES To assess whether HOUSES (HOUsing-based index of socioeconomic status (SES)) is associated with risk of and mortality after rheumatoid arthritis (RA). DESIGN We conducted a population-based case-control study which enrolled population-based RA cases and their controls without RA. SETTING The study was performed in Olmsted County, Minnesota. PARTICIPANTS Study participants were ...

PURPOSE We present the concept of the Green House, articulated by William Thomas as a radically changed, "deinstitutionalized" nursing home well before its first implementation, and we describe and discuss implications from the first Green Houses in Tupelo, Mississippi. DESIGN AND METHODS Green Houses are small, self-contained houses for 10 or fewer elders, each with private rooms and full ba...
