CHEMICAL AND BIOLOGICAL STABILITY OF PNA

Natural products – Discover their challenge and beauty
Natural products have always been among the most fascinating objects of the
practicing chemist. In fact, in many definitions of chemistry the isolation, purifi
cation and structural elucidation of natural products plays a central role. The his

The stability criteria subsystem CR covers the functions related to handling of intact stability criteria and damage stability
criteria. The purpose of the subsystem is to:
■ calculate the minimum GM and the maximum KG as a function of draught and trim, which assures compli[r]

Abstract. This paper studies both nonautonomous stochastic differential
equations and stochastic differential delay equations with Markovian
switching. A new result on almost sure stability of stochastic
differential equations is given. Moreover, we provide new conditions for
tightness and almost su[r]

This paper deals with the finitetime stability and H∞ control of linear discretetime
delay systems. The system under consideration is subject to interval timevarying
delay and normbounded disturbances. Linear matrix inequality approach is used to
solve the finitetime stability problem. First, new su[r]

During green revolution intensive use of chemical in agriculture might have helped to achieve a dramatic increase in crop yield ensuring food security in India, but meanwhile, the intensive application of chemical fertilizers and pesticides led to gradual decline in soil health and environment, and[r]

t. The stability analysis for linear implicit mth order difference equations is discussed.
We allow the leading coefficient coefficient to be singular, i.e., we include the situation that the system
does not generate an explicit recursion. A spectral condition for the characterization of asymptotic[r]

Most analytical experiments produce measurement data which require
to be presented, analysed, and interpreted in respect of the chemical
phenomena being studied. For such data and related analysis to have
validity, methods which can produce the interpretational information
sought need[r]

We establish formulas for computingestimating the Fr´echet and Mordukhovich
coderivatives of implicit multifunctions defined by generalized equations in Asplund spaces.
These formulas are applied to obtain conditions for solution stability of parametric variational
systems over perturbed smoothbound[r]

We propose several additional kinds of semilimits and corresponding
notions of semicontinuity of a setvalued map. They can be used additionally to
known basic concepts of semicontinuity to have a clearer insight of local behaviors
of maps. Then, we investigate semicontinuity properties of solution m[r]

Polypropylene/ maleic anhydride /organic montmorillonite nanocomposites (PP/ MA/ Org-MMT) have been prepared via direct melt intercalation in an internal mixer. Maleic anhydride (MA) was used as a compatibilizer to improve the dispersability of the clay. The structures of nanocomposites have been ch[r]

It is widely recognized that unregulated harvesting and hunting of biological resources
can be harmful and endanger ecosystems. Therefore, various measures to
prevent the biological resources from destruction and protect the ecological environment
have been taken. An effective resolution is to desig[r]

The brinjal variety Hisar Shyamal (H-8) is popular among farmers in the state of Haryana and neighbouring states of India. It experiences huge losses in fruit yield as it is not resistant to devastating seed borne diseases viz. damping off and fruit rot caused by Phomopsis vexans in addition to othe[r]

Identify the four major elements; distinguish between the following pairs of terms: neutron and proton, atomic number and mass number, atomic weight and mass number; distinguish between and discuss the biological importance of the following: nonpolar covalent bonds, polar covalent bonds, ionic bonds[r]

This paper describes the formulation of two polymer-bonded explosives based on RDX (hexahydro-1,3,5- trinitro-1,3,5-triazine) and fluoroelastomer binders by the water-slurry coating method. The fluoroelastomers are poly(VDF-HFP) (vinylidene fluoride-hexafluoropropene copolymer) and poly(VDF-CTFE) (v[r]

We shall deal with some problems concerning the stability domains, the
spectrum of matrix pairs, the exponential stability and its robustness measure
