Natural dyes, obtained from plants, insects/animals, and minerals, are renewable sustainable bioresource products with minimum environmental impact. However, there still many issues to solve related natural dyes; consequently, synthetic dyes wildly used. have a low affinity towards the substrate cotton, so solution had be found: mordants. Mordants can also harmful environment, which is why bio-...

Sun protection fabrics are designed to absorb or reflect the sun’s UV radiation as a means of protecting the skin from damage. The rating system for fabrics specifies an Ultraviolet Protection Factor (UPF) value, which can be thought of as a time factor for the protection of Caucasian skin compared to exposure without any protection. For example, if a person would show visible erythema (sunburn...

BACKGROUND Schizophrenia remains a priority condition in mental health policy and service development because of its early onset, severity and consequences for affected individuals and households. AIMS AND METHODS This paper reports on an 'extended' cost-effectiveness analysis (ECEA) for schizophrenia treatment in India, which seeks to evaluate through a modeling approach not only the costs a...

In order to perform precise evaluation of MANET applications in the real world, realistic mobility models are needed in wireless network simulation. In this paper, we propose a new method to create urban pedestrian flows (UPF) mobility scenarios, which reproduce the walking behavior of pedestrians in urban areas. From given densities of pedestrians observed at several points, our method derives...

Moving object tracking is one of the typical applications in wireless sensor network (WSN). As a result, a lot of important solutions have been proposed in the last decade, toward addressing different aspects of object tracking in WSN settings. This work describes an Unscented particle filter (UPF) based Moving Object Tracking algorithm, UMOT, in WSN settings, where the sensor nodes are cluster...

A hierarchical statistical model is made up generically of a data model, a process model, and occasionally a prior model for all the unknown parameters. The process model, known as the state equations in the filtering literature, is where most of the scientist’s physical/chemical/biological knowledge about the problem is used. In the case of a dynamically changing configuration of objects movin...

Soil nitrogen (N) processes and inorganic N availability are closely coupled with ecosystem productivity and various ecological processes. Spatio-temporal variations and environmental effects on net N transformation rates and inorganic N concentrations in bulk soil and ion exchange resin were examined in an upland pine forest (UPF) and a bottomland alder forest (BAF), which were expected to hav...

The CTF13 gene codes for a subunit of the kinetochore in Saccharomyces cerevisiae. The temperature-sensitive mutation ctf13-30, which confers reduced fidelity of chromosome transmission, is a G --> A transition causing an amino acid substitution of Lys for Glu146. Strains carrying one chromosomal copy of ctf13-30 fail to grow at the restrictive temperature, whereas a haploid strain carrying two...

In yeast, the accelerated rate of decay of nonsense mutant mRNAs, called nonsense-mediated mRNA decay, requires three proteins, Upf1p, Upf2p, and Upf3p. Single, double, and triple disruptions of the UPF genes had nearly identical effects on nonsense mRNA accumulation, suggesting that the encoded proteins function in a common pathway. We examined the distribution of epitope-tagged versions of Up...

Ultrasonic peen forming (UPF) is an emerging technology that exhibits great superiority in both its flexible operating modes and the deep residual stress it produces compared with conventional plastic methods. Although ultrasonic transducers longitudinal vibration have been widely studied, they seldom incorporated into UPF devices for machining confined spaces. To meet requirements of this type...
