The performance of carbon rod (CR), titanium sheet (TS), stainless steel woven mesh (SSM) and copper sheet (CS) cathode materials are investigated in microbial fuel cells (MFCs) for simultaneous electricity generation and Cu(II) reduction, in multiple batch cycle operations. After 12 cycles, the MFC with CR exhibits 55% reduction in the maximum power density and 76% increase in Cu(II) removal. ...

This issue of Systemic Practice and Action Research, celebrating the work of Peter Checkland, in the particular nature and development of soft systems methodology (SSM), would not have happened unless the work was seen by others as being important. No significant contribution to thinking happens without a secondary literature developing. Not surprisingly, many commentaries have accompanied the ...

I point out that all the arguments available in the literature against an astrophysical solution of the solar neutrino problem(s) do not exclude a yet not recognised class of solar models, in which an explosive energy source is present in the solar core besides the standard proton-proton and CNO cycle. It is shown from first principle physics that stars have a non-equilibrium energy source as w...

The effects of body size and feed intake on N digestibility, pancreas and Liver weight, and digestive enzyme activities in male broiler chicks were compared with those induced by dietary tannins. Four groups (SSM, ad lib., pair-fed and young) of sixteen birds each (2 weeks old) were used as experimental animals. They were fed on experimental diets for 4 weeks, except the young group which were ...

Schwarzer M, Schrepper A, Amorim P, Osterholt M, Doenst T. Pressure overload differentially affects respiratory capacity in interfibrillar and subsarcolemmal mitochondria. Am J Physiol Heart Circ Physiol 304: H529 –H537, 2013. First published December 15, 2012; doi:10.1152/ajpheart.00699.2012.—Years ago a debate arose as to whether two functionally different mitochondrial subpopulations, subsar...

To evaluate the scalar ocean surface wind speeds obtained from the Special Sensor Microwave Imager (SSM/I) we compare them over the time period from July 1987 through December 1997 with those from two global analyses: the NCEP/NCAR Annual Reanalysis and the ECMWF TOGA Global Surface Analysis. We perform a statistical analysis for the whole globe and present time series analyses for selected geo...

State-space models (SSM) are increasingly applied in studies involving biotelemetry-generated positional data because they are able to estimate movement parameters from positions that are unobserved or have been observed with non-negligible observational error. Popular telemetry systems in marine coastal fish consist of arrays of omnidirectional acoustic receivers, which generate a multivariate...

I derive conservative upper bounds on the supersymmetry breaking parameter m1/2 as a function of the strong coupling in the Standard Supersymmetric Model (SSM) using gauge coupling unification. I find that over more than 99% of the parameter space, α3 > 0.120 implies that m1/2 is below 10TeV and α3 > 0.129 implies that m1/2 is below 1TeV. I express the variation of these bounds over the SSM par...

In this paper, we present Scene Structural Matrix (SSM) and apply it to the retrieval of landscape images. The SSM captures the overall structural characteristics of the scene by indexing the geometric features of the image. A binary image tree (bintree) is used to partition the image and from which we derive multi-resolution geometric structural descriptors of the image. It is shown that SSM i...

Management has become a key concern for the success of multicast deployment in the Internet. One of the most important management tasks for multicast is to verify the availability of the service to its users. This task is referred to as discovering or testing reachability. In this paper, we present a new mechanism, SSM-Ping, for discovering multicast reachability between (remote) end systems in...
