n-methylol dimethyl phosphonopropionamide (mdpa) is one of the most utilized fire resistant (fr) finishes for cotton fabrics, utilized as part of a formulation with trimethylol melamine (tmm) to acquire better crosslinking and enhanced fr properties. the system parameters of the finishing treatment were upgraded for better fr properties and low mechanical loss to the fabric by the response surf...

In engineering design problems, we want to make sure that a certain quantity c of the designed system lies within given bounds – or at least that the probability of this quantity to be outside these bounds does not exceed a given threshold. We may have several such requirements – thus the requirement can be formulated as bounds [F c(x), F c(x)] on the cumulative distribution function Fc(x) of t...

Background & Aims: High concentrations of selenite have carcinogenetic, cytotoxic and genotoxic effects. Therefore, removal of this toxic pullutant from the environment has a particular importance in maintaining public health. In this study, with the aim of optimization of selenite removal process, the design Box-Behnken method was used to estimate th...

the main objective of the present study is to investigate the feasibility of using carboxymethyl chitosan magnetic nanoparticles (ccmn) for the adsorption of cd2+. the study also reports important parameters, which affect the adsorption process, i.e., ph, adsorbent dose, contact time and concentration of cd2+, using box-behnken designs. firstly, functional carboxymethyl chitosan magnetic nanopa...

introduction: fructans are an important product of the industry of prebiotics. in addition to their interesting nutritional and health benefit properties, fructans are also used in food formulations for their techno-functional properties such as fat substitute, bulk agent, water retention. serish (eremurus spectabilis) belongs to the family of liliaceae and geographically distributed in the reg...

Customers are ultimate judges of products. In order to produce the world-ranking product, customer information must be embodied in the part of production and hierarchy of control. This paper firstly points out the deficiency of QFD and the superiority of TRIZ. And then it constructs the application system of integrating QFD and TRIZ based on the theoretical rationale of the integration. The mai...

A method for the automatic generation of test scenarios from the behavioral requirements of a system is presented in this paper. The generated suite of test scenarios validates the system design or implementation against the requirements. The approach proposed here uses a requirements model and a set of four algorithms. The requirements model is an executable model of the proposed system define...

Hash functions, most notably MD5 and SHA-1, initially crafted for use in a handful of cryptographic schemes with specific security requirements, have become standard fare for many developers and protocol designers who treat them as black boxes with magic properties. This strategy had paid off until 2004—both functions appeared to have withstood the test of time and intense scrutiny of cryptanal...

This paper investigates the vibration isolation performance of isolated box structures. Isolated box inside building is a one of the building isolation designs. Some experimental methods are developed to analyze the effects of bending mode of the box structure on vibration isolation efficiency. The vibration reduction performance of an isolated box inside building is found to be degraded by ben...
