We have described a novel red biochrome, 514 Da in size, produced by solid-state cultivation of a bacterial isolate obtained from garden soil. The growth requirements of the isolate, the chemical characteristics of the biochrome produced, and the application of the biochrome in dying of silk, wool, and cotton fabrics have been studied. The biochrome obtained after 52 h of incubation and having a λ max of 535 nm was used for dyeing the fabrics. We found that silk, wool, and cotton fabrics dyed with this new natural red compound have high color strength values and dye uptake along with good color fastness as well as antibacterial activity. © 2011 Springer Science+Business Media, LLC.

A particle filter, specifically a Bayesian bootstrap filter algorithm, is applied for estimating the state vector that characterizes the orbit of a satellite, using a set of GPS measurements. The development will be evaluated through performance and computational cost, comparing the bootstrap algorithm results against the unscented Kalman filter (UKF) solution for the same problem. The orbit determination is a nonlinear problem, with respect to the dynamics and the measurements equations, in which the disturbing forces and the measurements are not easily modeled. It consists essentially of estimating values that completely specify the body trajectory in the space, processing a set of measurements related to this body. Such observations can be collected through a tracking network grounded on Earth or through sensors, like GPS receivers onboard the satellite. The GPS is a wide spread system that allows computation of orbits for artificial Earth satellites by providing many redundant measurements (pseudo-ranges). The bootstrap filter is proposed for implementing recursive Bayesian filters. It is a statistical, brute-force approach to estimation that often works well for systems that are highly nonlinear. Here, the bootstrap particle filter will be implemented with resampling and roughening, a scheme for combating the reduction in the number of truly distinct sample values.

Choline chloride: a 2ZnCl2 based deep eutectic solvent was found to be a simple, green, efficient and new solvent system for the preparation of primary amides from aldehydes. The same catalytic system is also applicable for the preparation of amides from nitriles. Good to excellent yields of primary amides were obtained in both these transformations. © 2014 The Royal Society of Chemistry.

Exploring the symbiotic nature of biological systems can result in valuable knowledge for computer networks. Biologically inspired approaches to security in networks are interesting to evaluate because of the analogies between network security and survival of human body under pathogenic attacks. Wireless Sensor Network (WSN) is a network based on multiple low-cost, low-energy sensor nodes connected to physical signals. The network is made up of sensor nodes and gateways, where the server nodes acquire physical world data, while the gateway forwards the data to the end-user. While the spread of viruses in wired systems has been studied in-depth, applying trust in wireless sensor network nodes is an emerging area. This paper uses machine learning techniques to first differentiate between fraudulent and good nodes in the system. Next, it derives inspiration from the human immune system to present an idea of virtual antibodies in the system, to disable the fraudulent nodes in the system. © 2013 IEEE.

We present extensive atomistic molecular dynamics simulations of the structure and stability of fullerene-based membranes. The simulations provide a molecular description of the PhK (pentaarylfullerene anions, C60Ar5-·K+) and C8K (C60Ar5-·K+ with octyl substituents) membranes. Physical chemical properties and molecular organization of PhK and C8K membranes elucidate various aspects related to their formation and potential applications. Our simulations evidence that such membranes are robust and stable. PhK membranes proved very stable and compact. Considering experimental evidence, PhK bilayer is an adequate model for the surface of the PhK vesicle. © 2014 American Chemical Society.

Wheat is a staple food throughout the world. Sprouted wheat contains numerous vitamins, secondary plant ingredients, enzymes, mineral nutrients and trace materials. The present work was carried on drying of sprouted wheat (Triticum aestvum) in a laboratory fluidized bed using different operating conditions. Physical properties including bulk density, tapped density, particle density and porosity were determined for various forms of wheat. The proximate analysis and handling properties were measured. The entire drying period was considered to follow falling rate period. The experimental data were modeled using Fick's diffusion equation and the effective diffusivity coefficients were found to be within the range of 7.310-10 to 30.410-10 m2/s. Malting caused significant increase in protein content. During drying lightness increased, while yellowness and redness decreased. The dehydrated sprouted wheat exhibited excellent reconstitution and keeping quality. The dehydrated sprouted wheat flour can be used for making noodles, pasta, laddu, bread, unleavened bread, porridge and gruels for newborns. © 2014 Walter de Gruyter GmbH, Berlin / Boston.

Originality/value: BPO/ITES firms in India tend to focus only on cost reduction from IT outsourcing without taking into consideration other equally important drivers such as strategy and risk. This paper counsels a holistic approach toward IT outsourcing for a successful outcome. In addition, an IT-outsourcing framework and guide is proposed for practitioners.Purpose: The purpose of this paper is to understand the roles various drivers such as cost, strategy and risk play when business process outsourcing/information technology enabled services (BPO/ITES) firms in India outsource their information technology (IT) functions to third-party vendors. If all key drivers associated with IT outsourcing were understood, and such knowledge of those variables was incorporated into the reasons for outsourcing, there would be a greater probability of a successful outcome.Design/methodology/approach: A “hybrid” (quantitative and qualitative) research methodology was used to gain insight into the IT-outsourcing paradigm by BPO/ITES firms in India. A structured questionnaire related to IT-outsourcing activities conducted from 1999 to 2010 was distributed to nine firms. The resulting data were then analyzed. In addition, two Indian BPO/ITES firms that had outsourced their IT to a third-party vendor to cut cost generously granted in-depth information into their IT-outsourcing paradigm and life cycle.Findings: IT outsourcing is perhaps more complicated than other types of outsourcing. Focussing purely on cost is very risky. Practitioners need to take all three drivers – cost, strategy and risk into consideration. Any degradation of services or responsibilities due to IT outsourcing would mean a very unhappy client or even loss of business. © Emerald Group Publishing Limited.

In the current study, bamboo rayon fabrics grafted with mixture of acrylic acid and acrylamide was utilized as a backbone to immobilize ZnO nanoprticles. The swollen grafted fabric was treated with ZnCl2 followed by conversion of Zn2+ ions into ZnO nanoparticles. The modified product was characterized using FTIR, TGA and SEM and then evaluated for antibacterial activity against gram positive and gram negative bacteria as well as durability of their antibacterial activity after washing. The product showed antibacterial activity against both types of bacterias which was found to be durable till 40 washes. The modified material also showed improved UV protection because of presence of ZnO nanopartcles. The product can be claimed as suitable sustainable candidate for textile products in health and well being of the users. © (2013) Trans Tech Publications, Switzerland.

International Coding Technologies, Inc. (ICT) announces the unveiling of ‘Idencia Monthly’, a pay-as-you-go alternative for its Idencia product tracking service used by manufacturers of concrete products. ICT’s customers use Idencia to reduce the cost of managing inventory and maintaining quality control records. To get started, customers pay a small set-up fee for: Rather than paying for an annual subscription up-front, subscribers to Idencia Monthly pay for the first 3 months then pay monthly thereafter. They may discontinue use of the service at any time without cost or penalty. In announcing the release, CEO, Jeff Pollock, stated: “With Idencia Monthly we assume the financial risk of success, not the customer. We’re happy to do that because we don’t see it as a risk at all.” He added: "By removing the up-front cost of an annual subscription, the customer can now realize an immediate financial return from using Idencia." ICT’s year-over-year customer growth from new annual subscribers has been more than 50% in 2016. However, ICT reports that a substantial subset of potential subscribers defer out of a desire to learn more about Idencia before making a financial commitment. Idencia Monthly is offered to allow these prospects to learn more without commitment in the most effective way… by using it. For more information, please contact: Jeffrey M. Pollock, CEO; jpollock(at)idencia(dot)com. International Coding Technologies, Inc. (Topsfield, MA) offers the Idencia system, a product tracking service that advances productivity in the manufacture, construction and maintenance of products used in public infrastructure such as bridges, tunnels and railroad track. The company sells to manufacturers of precast concrete, pre-stressed concrete and steel products throughout the world.
