Engineers from Duke University are reporting results from the first large-scale, real-world field trials of critical components of their off-grid sanitation system funded by the Bill & Melinda Gates Foundation's 'Reinvent the Toilet' program. Besides being pleasantly surprised at the longevity of their system and discovering their nutrient removal processes needed improvement, the Duke researchers were reminded of just how important cultural practices can be to the success of a global engineering challenge.
Standard comfort measurements used to design heating and cooling systems share a common flaw, according to new research. The researchers said the error was caused by the standard instrument used to measure thermal effects of radiant heating and cooling. The instrument and associated formulas used to calculate comfort based on the sensor's readings do not properly account for air flow called free convection. The failure led to temperature errors of over two degrees Celsius.
Research by an international team of scientists led by University of New Mexico Professor Yemane Asmerom suggests contraction of the Intertropical Convergence Zone (ITCZ) during a warming Earth, leading in turn to drying of the Neotropics, including Central America, and aggravating current trends of social unrest and mass migration.
New work reconciles divergent methods used to analyze the scaling behavior of cities.
For the first time, a study led by the University of Bergen and the Barcelona Institute for Global Health (ISGlobal), a centre supported by 'la Caixa', has found that living in a greener neighbourhood is associated with older age at the onset of menopause.
Academics at UCL have identified 18 reasons why megaprojects such as HS2 and Crossrail often fail, as well as 54 preventative solutions. For the first time, academics developed a systematic literature review of the causes and cures of poor megaproject performance. They identified six key themes and looked at areas where a project might fail, analysing the problems and solutions. The study was published in Project Management Journal.
Food waste is a big problem in the United States. According to the US Department of Agriculture, food waste is estimated at between 30-40 percent of the food supply. New research in the INFORMS journal Manufacturing & Service Operations Management finds that increasing the number of grocery stores in certain areas can drastically decrease waste.
How to teach citizens to become active members of the society? Peter Ehrström, Head of Research in Regional Science, and Marina Lindell, Project Researcher at the Social Science Research Institute of Åbo Akademi University in Vaasa, Finland, approached the question by inviting a group of students on a course that utilized a method called Deliberative Walks. The experiment produced very positive results.
A growing body of research shows that the behavior of peers can significantly influence an individual's energy-related decisions, but why that occurs is less clear. A new paper provides insights into the factors that underpin the effectiveness of peer influence - and how it might be used to promote more sustainable energy choices.
During a typical Canadian winter, snow accumulation and melt--combined with sudden rainfalls--can lead to bottlenecks in storm drains that can cause flooding. With that in mind, researchers at UBC's Okanagan campus have been examining urban stormwater drainage systems, and they too have concerns about the resilience of many urban drainage systems
