We derive two classes of brane-world solutions arising in the presence of a bulk scalar field. For static field configurations, we adopt a time-dependent, factorizable metric ansatz that allows for radion stabilization. The solutions are characterized by a non-trivial warping along the extra dimension, even in the case of a vanishing bulk cosmological constant, and lead to a variety of inflatio...

We prove a sharp decay rate for the total energy of two classes of systems of weakly coupled hyperbolic equations. We show that we can stabilize the full system through a single damping term, acting on one component only of the system (indirect stabilization). The energy estimate is achieved by means of suitable estimates of the resolvent operator norm. We apply this technique to a system of wa...

This paper has two themes. In the first instance, we are concerned with uncovering the impact of intellectual thought on the practice of economic policy specifically, the influence of Keynesianism on fiscal policy. Keynes' idea that national governments can stabilize aggregate economic activity, presented in his General Theory of Employment, Interest and Money (1936), is one of the most importa...

κ-casein is a glycosilated protein belonging to a family of phosphoproteins (αs1,β, αs2,κ) that represents the major protein component in mammalian milk. κ-casein plays an essential role in the case of micelle stabilization, determining the size and the specific biological function. In the present study, we report the characterization of the partial sequence of κ-casein promoter region in the I...

Silver particles of nanometric size were prepared from silver sulphate solution using Curcuma Longa and Zingiber Officinale rhizome extracts. The reaction was completed at 3 hours on using Curcuma Longa rhizome extract as reducing agent, making it one of the fastest biosynthesis route reported so far. The plasmon bands at 420 nm in the UV visible spectra are broad with an absorption tail in the...

Biomolecular recognition entails attractive forces for the functional native states and discrimination against potential nonnative interactions that favor alternate stable configurations. The challenge posed by the competition of nonnative stabilization against native-centric forces is conceptualized as frustration. Experiment indicates that frustration is often minimal in evolved biological sy...

chemical stabilization of heavy metals is one of the soil remediation methods based on the application amendments to reduce mobility of heavy metals. a laboratory study was conducted to investigate the influence of different kinds of amendments on cadmium (cd) stabilization in a cd-spiked soil. the amendments were municipal solid waste compost (mswc), coal fly ash (cfa), rice husk biochars prep...

Direct control of protein level enables rapid and efficient analyses of gene functions in crops. Previously, we developed the RDDK-Shield1 (Shld1) system in the model plant Arabidopsis thaliana for direct modulation of protein stabilization using a synthetic small molecule. However, it was unclear whether this system is applicable to economically important crops. In this study, we show that the...

We use the thermodynamic model introduced by Aptekar’ and Ponyatovskiy for the – transformation in cerium metal to study the properties f plutonium metal. The model describes the – transformation in Pu and explains the minimum in the melting versus pressure curves for both aterials. Ga stabilization of the -phase of Pu is explained in terms of a first order transition between the two phases. Th...
