bacillus thuringiensis (bt) has been extensively used in biopesticidal formulations due to its safe environmental and human health records. the widespread use of bt is often challenged by production as well as formulation costs which are in direct contact with downstream processing, i.e. the separation/purification step. downstream separation/purification efficacy governs the marketability of a...

nowadays, environment-sensitive smart drug delivery systems have found diverse applications in pharmaceutical science and technology. these systems can respond to the environment stimuli such as temperature, pressure, ph, light, electrical and magnetical fields and etc. they can release the proper amount of drug in human body. among these systems, special attention and much research works have ...

The inter-grey-level response times of an LCD are studied using two different approaches: a 3-D finite-elements dynamic director orientation model and a simple firstorder RMS model. Both approaches are compared with measurements, showing that for certain applications, the RMS model is a quick and sufficiently reliable response time prediction tool.

A haptic device using flexible sheet such as rubber has already been proposed. Controlling the bias tension of the sheet, the device varies compliance of the sheet in the normal direction; users can feel compliance of various virtual objects if they touch the sheet. This device is integrated into a visual and haptic display. The haptic device uses transparent flexible sheet, and a liquid crysta...

Mobile radio network with cellular structure demand high spectral efficiency for minimizing number of connections in a given bandwidth. One of the promising technologies is the use of “Smart Antenna”. A smart antenna is actually combination of an array of individual antenna elements and dedicated signal processing algorithm. Such system can distinguish signal combinations arriving from differen...

In this paper we look at possibilities to introduce humorous situations in smart environments. The assumption is that in future smart environments we have the possibility to configure and even real-time reconfigure environments in a way that humorous situations can be created or that conditions for humorous situations to emerge can be implemented. However, in order to do so we need to investiga...

As the augmented reality technology has become more pervasive and applicable, it is easily seen in our daily lives regardless of fields and scopes. Existing camera vision based augmented reality techniques depend on marker based approaches rather than real world information. The augmented reality technology using marker recognition has limitations in its applicability and provision of proper en...

firms invest in their learning activities to improve their innovative efforts. these kinds of activities are either internal or external. knowledge which flows among local actors is one of the external learning factors. spontaneous knowledge flows among firms without any compensation or with compensation less than the real value is called knowledge spillover. this paper analyzes the effect of k...

This paper investigates how expansion and compression of the surface of a drop containing an organic compound, 1-octanol, affect surface tension. The experiments were performed in a closed chamber where the effect of 1-octanol concentrations in both liquid and gas phases on the surface could be studied. The concentration of 1-octanol varied from 0.2 mM to 2.92 mM (about 70% of it’s water solubi...

Background: With the rapid population ageing that is occurring world-wide, there is increasing interest in “smart home” technologies that can assist older adults to continue living at home with safety and independence. This systematic review and critical evaluation of the world wide literature assesses the effectiveness and feasibility of smart-home technologies for promoting independence, heal...
