Disentangling the individual and interactive effects of multiple stressors on microbial communities is a key challenge to our understanding and management of ecosystems. Advances in molecular techniques allow studying microbial communities in situ and with high taxonomic resolution. However, the taxonomic level which provides the best trade-off between our ability to detect multiple-stressor ef...

An m × n row-column factorial design is an arrangement of the elements a into rectangular array. Such array used in experimental design, where rows and columns can act as blocking factors. Formally, for any integer q, let [ q ] = { 0 , 1 … − } . The k (full) with replication α multiset consisting occurrences each element ; we denote this by A regular (which say type I ( ) such that row (column)...

BACKGROUND Access to sanitation facilities is imperative in reducing the risk of multiple adverse health outcomes. A distinct disparity in sanitation exists among different wealth levels in many low-income countries, which may hinder the progress across each of the Millennium Development Goals. METHODS The surveyed households in 397 clusters from 2008-2009 Kenya Demographic and Health Surveys...

Commercial chip design verification is a complex activity involving many abstraction levels (such as architectural, register transfer, gate, switch, circuit, fabrication), many different aspects of design (such as timing, speed, functional, power, reliability and manufacturability) and many different design styles (such as ASIC, full custom, semi-custom, memory, cores, and asynchronous). In thi...

We present a comparative study between a complex Wavelet Coeecient Shrinkage (WCS) lter and several standard speckle lters that are widely used in the radar imaging community (Lee, Kuan, Frost, Geometric, Kalman, Gamma, etc.). The WCS lter is based on the use of Symmetric Daubechies (SD) wavelets which share the same properties as the real Daubechies wavelets but with an additional symmetry pro...

BACKGROUND Exposures to occupational hazards substantially increase workers' risk of developing musculoskeletal disorders (MSDs) and can exacerbate pre-existing disorders. The effects on MSD risk of the physical requirements of work performance are well recognised, but there is now ample evidence that work-related psychosocial hazards can also have substantial effects; further, some hazards may...
