When fruit juices of various fruits are blended in a specific ratio the nutritious quotient of the drink gets optimized. This research paper proposes to study the optimization levels when three or more fruit juices of different physical and chemical compositions are mixed to gain the optimum nutrition value. This optimization is studied by Response Surface Methodology (RSM). The paper also attempts to study the desired physical and chemical properties to get the optimum nutritive values. The mixed fruit juice of less caloric value is taken for study. The fruits taken for extracting juice include orange, pineapple, and tamarillo (Tree Tomatoes) which are tasty with their acidic quality. The result of this study gives the utmost recommended combinations of the fruit juice mixture which is read as 50% of Orange and 50% of pineapple and 33% orange, 33% pineapple, and 33% tamarillo.

The optimization of the osmotic dehydration of the pomegranate arils is done by Response Surface Methodology. The optimization is calculated by varying the three variables – Temperature, Brix Concentration and Duration. The minimum and maximum levels for each variable are fixed. Thus the minimum for temperature is 49°C and maximum is fixed as 113°C. In the same way the minimum of Brix concentration of the osmotic solution is 42° and maximum is 58°C. The maximum duration for dipping in osmotic solution is at a minimum of 40 minutes and a maximum of 53 minutes. The sucrose solution is used as the osmotic solution by varying the Brix, temperature, and duration. 1:4(W/W) ratio for fruit to solution respectively is used for overall experiments. The whole pomegranate is frozen up to -18°C before dipping it in the solution to allow high permeability of the outer cell layers of pomegranate arils. The moisture of the arils is further maintained to 10% (wb) by dehydrating convectively at 60°C to make it SSP. The optimized condition parameters of the three variables Temperature, Concentration and Duration of the osmotic dehydration process are fixed as 80-90°C, 40-50° Brix, and 40-60 minutes respectively.

This paper presents the development of flexible capacitive sensor for measuring three dimensional forces to monitor and early detection of pressure ulcers. The wide range of capacitive sensors can be used for many industrial applications which include the measurement of applied pressure and force. The accurate measurement of pressure becomes essential key parameters to analyses the behavior of sensor based biomedical measurement system for different applications. In most situations, people with severe motor impairments have very low sensitivity in parts of the body that come into contact with supporting surfaces such as beds and wheel chairs. As a result of the pressure surpassing the tissue for an extended period of time, tissues are deprived of oxygen and necessary nutrient which leads to the development of pressure ulcers. Monitoring three-axis force that people with severe motor impairments exert on supporting surfaces is one technique to reduce the risk of pressure ulcer formation. This paper proposed the novel design of capacitive sensor to monitor three axis forces in all dimensions. Here, a custom developed sensor with capacitance to digital converter is used to convert the sensor's capacitance to a digital value. The proposed converter can be used to measure the capacitance in the range of 0 to 260pF and stored in device memory for easy access and processing. The low power ARM Cortex M3 processor with serial communication protocol is configured in embedded programming environment to acquire the signal from the proposed sensor and the capacitance variation is displayed on the OLED.

Polymerized ionic liquids (PILs) were successfully prepared by using 4-(vinylbenzyltrimethyl)ammonium, [VBTMA] as the cation and alanine as the anion. The monomer [VBTMA]Ala was reacted with AIBN as radical initiator to produce poly[VBTMA]Ala. The polymer was characterized by using NMR and FTIR. Thermal degradation behavior for Poly[VBTMA]Ala was 168.70 °C and glass transition temperature (Tg) was not detected even at second cycle. The surface area, pore size and pore volume were determined by using BET surface area and pore size analyzer which showed that Poly[VBTMA]Ala has mesoporous structure. The morphology was determined by FESEM. The CO2 adsorption was measured by gas adsorption cell which showed that the mole of CO2 adsorb increased as pressure increased. [ABSTRACT FROM AUTHOR]
