ownload purpose of this study was to determine the anticancer efficacy of 1,1-bis (3′-indolyl)-1-(p-biphenyl) ne (DIM-C-pPhC6H5) by inhalation delivery alone and in combination with i.v. docetaxel in a murine for lung cancer. An aqueous DIM-C-pPhC6H5 formulation was characterized for its aerodynamic propTumor-bearing athymic nude mice were exposed to nebulized DIM-C-pPhC6H5, docetaxel, or combi...
A novel robust adaptive beamforming method for conformal array is proposed. By using interpolation technique, the cylindrical conformal array with directional antenna elements is transformed to a virtual uniform linear array with omni-directional elements. This method can compensate the amplitude and mutual coupling errors as well as desired signal point errors of the conformal array efficientl...
– Small-angle X-ray scattering and phase-contrast microscopy experiments were performed to investigate the effect of the osmotic pressure on vesicle formation in a dioleoylphosphatidylcholine (DOPC)/water/NaI system. Multi-lamellar vesicles were formed when a pure lipid film was hydrated with an aqueous solution of NaI. On the other hand, uni-lamellar vesicles (ULVs) were formed when a lipid fi...
Respiratory diseases constitute a major health problem in small ruminant herds around the world, and parainfluenza virus type 3 (PIV-3) has been shown to play vital role their etiology. This cross-sectional study describes serological status of non-vaccinated dairy goat popu- lation Poland with respect PIV-3 infection investigates relationship between presence antibodies some basic herd-level a...
Abstract A new synchronous machine model is presented which is readily implemented in either circuit-based or differentialequation-based simulation programs. This model is well suited for the simulation and analysis of synchronous machine converter systems. It is based upon standard representations and no approhations are made in its derivation. However, the numerical implementation is shown to...
Campylobacter jejuni is now world-wide recognized as a zoonotic agent of bacterial diarrhoea in human beings 2 1 2 . Many domestic animals are intestinal carriers of these bacteria and could be a probable source of human in fection M, Dogsparticulary puppies, may be responsible for the transmission of Campylo bacter to human contacts. Campylobacter iso lation rates varies between 6-52.2% dep...
A b st r act . The relationship between "learning" in ad aptive layered networks and the fit ting of data wit h high dimensional surfaces is discussed . T his leads natu rally to a picture of "generalization" in terms of interp olation between known data points and suggests a rat ional approach to th e theory of such networks. A class of adaptive networks is identified which makes the inte rpo ...
High-performance scientiic computing relies increasingly on high-level large-scale object-oriented software frameworks to manage both algorithmic complexity and the complexities of parallelism: distributed data management, process management, inter-process communication, and load balancing. This encapsu-lation of data management, together with the prescribed semantics of a typical fundamental c...
Cells from photoautotrophic cultures o f Chenopodium rubrum were fractionated for the iso lation o f purified chloroplasts and mitochondria. The subcellular localization o f the enzymatic activities involved in the metabolism o f malic acid was investigated. Highly purified chloro plasts were obtained from the protoplasts, whereas peroxisomes were still present in the mito chondrial fraction...
Sociometer theory proposes that the self-esteem system evolved as a monitor of social acceptance, and that the so called self-esteem motive func tions not to maintain self-es teem per se but rather to avoid social devaluation and rejec tion. Cues indicating that the individual is not adequately valued and accepted by other people lower self-esteem and motivate behaviors that en hance relational...
