Effect of Oxygen Content on Magnetic Properties of Layered Cobaltites PrBaCo2O5+\delta

The effect of oxygen content on the magnetic properties of the layered perovskites has been investigated. The samples, PrBaCo$_{2}$O$_{5+\delta}$ (0.35 $\leq \delta \leq$ 0.80) were prepared by sol-gel method and characterized by X-ray diffraction and DC magnetization. A detailed magnetic phase diagram for PrBaCo$_{2}$O$_{5+\delta}$ is presented. It is found that unlike in the case of heavier rare-earths, ferromagnetic interactions are present at all temperatures below Tc and even in the antiferromagnetically ordered phase. Moreover, in compounds with lower oxygen content, short range ferromagnetic interactions are present even above Tc. This dependence of magnetic properties on oxygen content in these layered perovskites has been linked to the changes in polyhedra around the Co ions.Comment: 20 pages, 10 figures; J. Appl.

Effect of flaxseed incorporation on physical, sensorial, textural and chemical attributes of cookies

Abstract Considering the potential of flaxseed as functional ingredient, roasted flaxseed flour (RFF) was incorporated by substituting refined wheat flour at 5%, 10%, 15%, 25% and 30% in cookies formulations. Thickness and diameter of cookies increased as flaxseed flour was increased. Addition of flaxseed restricted the spread of cookies. 15% flaxseed flour incorporated cookies were found to be well comparable with control in sensory evaluation. Hardness and fracturability of experimental cookies increased up to 15% flaxseed flour incorporation. Thereafter, both these attributes showed decline trend. Chemical composition showed that moisture, ash, fat and protein content increased in flaxseed flour cookies than control. Fiber content was nine times more in flaxseed flour cookies than the control. Alpha linolenic acid (ALA) content increased from 0.19% (control) to 4.76% in optimized cookies. An improvement in polyunsaturated to saturated fatty acid ratio was observed while ω-6 to ω-3 fatty acid found to be decreased to well below maximum recommended value

Heartbeat and Temperature Monitoring System for Remote Patients using Arduino

This paper describes the working of a wireless heartbeat and temperature monitoring system based on a microcontroller ATmega328 (arduino uno). Most monitoring systems that are in use in today\u27s world works in offline mode but our system is designed such that a patient can be monitored remotely in real time. The proposed approach consists of sensors which measures heartbeat and body temperature of a patient which is controlled by the microcontroller. Both the readings are displayed in LCD monitor. Wireless system is used to transmit the measured data from the remote location. The heartbeat sensor counts the heartbeat for specific interval of time and estimates Beats per Minute while the temperature sensor measures the temperature and both the data are sent to the microcontroller for transmission to receiving end. Finally, the data are displayed at the receiving end. This system could be made available at a reasonable cost with great effect
