Bovine mastitis is the most important source of loss for the growing dairy industry. Streptococci, with special reference to Streptococcus agalactiae, S. dysgalactiae and S. uberis, are the predominant pathogens causing bovine mastitis. A rapid, sensitive and specific test for the detection of these pathogens needs to be developed. To accomplish this, initially 163 milk samples were collected f...
ance. In addition, the salt composition of the soil water influences the composition of cations on the exchange Due in large measure to the prodigious research efforts of Rhoades complex of soil particles, which influences soil permeand his colleagues at the George E. Brown, Jr., Salinity Laboratory ability and tilth, depending on salinity level and exover the past two decades, soil electrical ...
During skeletal muscle excitation-contraction (EC) coupling, membrane depolarizations activate the sarcolemmal voltage-gated L-type Ca(2+) channel (Ca(V)1.1). Ca(V)1.1 in turn triggers opening of the sarcoplasmic Ca(2+) release channel (RyR1) via interchannel protein-protein interaction to release Ca(2+) for myofibril contraction. Simultaneously to this EC coupling process, a small and slowly a...
Electro-thermal actuation mechanism continues to attract attention of MEMS designers as a reliable method of delivering high displacements and high actuation forces [1]. The main purpose of this work is to conduct a coupled multi-physics FEA of a micro-machined electro-thermomechanical actuator (μETMA) in order to determine a nature of a common failure mode, suggest a better fabrication process...
Itai and Rodeh [IR] have proved thal for any 2-conncctcd graph G and any vertex S E G there are two spanning trees such that the paths from any othcr vcrtex to s on the trees are disjoint. In this p,aper the result is generalized to 3-connected graphs. T ec hn io n C om pu te r Sc ie nc e D ep ar tm en t T eh ni ca l R ep or t C S0 46 2 19 87 -1
In this work, high resolution integrated AFM–EC/SECM was used to reveal the spatially heterogeneous electroactivity of microcrystalline diamond (MCD) and nanocrystalline (NCD) surfaces. During electrochemical corrosion, NCD surfaces undergo a stronger corrosion reaction than MCD because higher amount sp2 hybridized carbon. In-situ EC-AFM imaging shows no significant change in surface morphology...
Photoinduced electron-transfer processes are enhanced or quenched by application of electric fields, depending on the donor–acceptor pairs. Electric-field-induced quenching of photoluminescence, which results from the field-induced dissociation of the exciton state that depends on the photoexcitation wavelength, is observed in π-conjugated polymers. These electric-field effects on photoinduced ...
This work reports the ordered self-assembly of nonconductive small molecules that achieved extra high conductivity, thereby stating an convenient approach for constructing a biofriendly soft material that is suitable to be used as implantable biosensors and electro-stimulated drug delivery systems. The microstructure and the conductive mechanism were investigated in detail by combining experime...
soil alkalinity and salinity are serious problems in arid and semi-arid regions, and therefore monitoring of soil ph and electrical conductivity (ec) is necessary in any region. the present study aimed to properly interpolate soil ph and ec as soil quality indices in a semi-arid mountainous area with annual precipitation of 342.4 mm. the study area is the karimabad rangelands in hamadan provinc...
Understanding the formation and spatial-temporal distribution of soil salt crusts (SSCs) is important for the sustainable management of the artificial shelterbelt and high-salinity groundwater utility in the Taklimakan Desert in Northwest China. The SSCs in this area were sampled, and their thickness and electrical conductivity (EC) were analyzed to examine the formation mechanism and the spati...
