Abstract We adapted the pyrogallol red-molybdate method for total urinary protein to Cobas Bio centrifugal analyzer. The is simple, rapid, sensitive, and inexpensive. Addition of 25 mg sodium dodecyl sulfate per liter reagent modifies reactivities so that chromogenicity human gamma globulins same as albumin. Results by this a comparison included gel filtration modified biuret reaction correlated well (r = 0.951).
Citizen Science initiatives have a worldwide impact on environmental research by providing data at global scale and high resolution. Mapping marine biodiversity remains key challenge to which citizen can contribute. Here we describe dataset made of both underwater aerial imagery collected in shallow tropical coastal areas using various low cost platforms operated either citizens or researchers. This is regularly updated contains >1.6 M images from the Southwest Indian Ocean. Most are...
Seven surface-exposed outer membrane proteins (OMPs) in Brucella supp. have been previously described (A. Cloeckaert, P. de Wergifosse, G. Dubray, and J. N. Limet, Infect. Immun. 58:3980-3987, 1990). OMPs were shown to be more accessible monoclonal antibodies (MAbs) on rough (R) melitensis B. abortus strains than MAbs their smooth (S) counterparts. In this work, we extended study representatives of the main species, using specific for S R lipopolysaccharides (S-LPS R-LPS). Enzyme-linked...

We have fabricated and characterized two high-power high-linearity uni-traveling-carrier photodiode (UTC-PD) structures. The UTC performances are compared regarding their respective collector design. A -3-dB bandwidth improvement (from 16-25 GHz to 19-32 GHz) is achieved when the layer thickness increased 250 350 nm, respectively). for large photocurrent at origin of a ldquosupra-linearityrdquo effect. Photocurrent saturation effects investigated -1-dB compression current measurements 20...
Bioluminescence, the light emitted naturally by marine organisms, is main source in mesopelagic zone. Nearly 75% of from surface to deep sea, use this capability for communication with diverse ecological goals (predation, repulsion...). Bioluminescence detection thus offers an indirect way tracking presence, distribution and migrations organisms (ranging zooplankton, dinoflagellates fishes). Such can lead example a better understanding vertical consequently quantification active carbon...

This paper discusses the viability of a BIST implementation for sinusoidal histogram technique classically used ADC testing. An original approach based on (i) approximations to estimate parameters, (ii) decomposition global test in code-after-code procedure and (iii) piecewise approximation compute ideal is developed. These three features allow significant reduction required operative resources as well memory dedicated storage both experimental reference data.
This paper validates a linear histogram BIST scheme for ADC testing. uses time decomposition technique in order to minimize the required hardware circuitry. A practical implementation is described and structure together with operating mode of different modules are detailed. Through this implementation, performances limitations proposed evaluated both terms additional circuitry test time.
This paper presents an alternate test implementation based on model redundancy that permits to achieve lower prediction errors than a classical implementation, even if training is performed over small set of devices. The idea build different regression models for each specification during the phase, and then verify consistency between production testing phase. In case divergent predictions, devices are removed from tier directed second where further may apply. approach illustrated real study...

5'-Nucleotidase from bovine liver plasma membranes has been extracted by the zwitterionic detergent sulfobetaine 14, and purified to apparent homogeneity. Two affinity chromatographies on concanavalin-A-Ultrogel 5' AMP-Sepharose 4B followed AcA-54-Ultrogel filtration resulted in a purification of 16000 times relative homogenate. Sodium dodecyl sulphate gel electrophoresis indicates that molecular weight subunit is 70000. Cross-linking native enzyme with dimethylpimelimidate shows band an...
