A water soluble carboxymethyl derivative of chitosan was prepared with a view to develop a multifunctional finish on cotton. Results show that treated cotton has better dyeability with direct and reactive dyes. Treatment with modified c...

Two types of mechanisms could lead to loss of cement-sheath integrity: mechanical and chemical degradations. However, chemical degradation by CO2 does not seem to be a real threat when the cement sheath is initially without default. Hen...

Nano-bioactive-glasses have been prepared by a quick alkali-mediated sol–gel method. The gelation time was around 2 min. The size of bioactive glasses could be controlled via addition of ammonia solution. The TEM images showed th...

Let p be an odd prime, and let K(n)∗ Cheap Bailey Button denote the nth Morava K-theory at the prime p; we compute the K(n)-Euler characteristic χn,p(G) of the classifying space of an extraspecial p-group G. Equivalently, we get the ...

This paper describes techniques suitable for tracking and guiding missiles to Mars and Venus or beyond. In simplest form, a system can be constructed utilizing these techniques, which requires only two ground stations a few thousand mil...

Drawing upon recent theoretical advances in the analysis of cooperation, this paper presents an econometric analysis of the determinants of successful collective action based on a survey of 104 peasant cooperative institutions in Paragu...

This note presents a simplified description of the Healthy Years Equivalent (HYE) health outcome measure. I examine the claims made for the HYE and discuss their theoretical validity. The Genuine Uggs HYE is shown to be conceptually fla...

Let G be a non-bipartite strongly regular graph on n vertices of valency k. We prove that if G has a distance-regular antipodal cover of diameter 4, then k ≤  2(n +  1) / 5, unless G is the complement of ...

An extended version of Kelley's cutting plane method is introduced in the present paper. The extended method can be applied for the solution of convex MINLP (mixed-integer non-linear programming) problems, while Kelley's cutting plane m...

This paper investigates the determinants of voluntary unionization in the labor market in a discrete-time version of the social custom model. Employer behavior in form of management opposition to union membership is explicitly taken int...
