In wireless sensor network generally people concentrate on minimization of energy consumption. Also, on reducing end-to-end delay and energy saving. This paper also proposes a TDMA-based protocol scheme that will balance energy saving and end-to-end delay. This is achieved by path scheduling assigned by graph coloring method. Our approach consist of three phases: in first phase, we have used Ge...

A simple method of preparing extracts of plasma or serum suitable for determination of both triglycerides and cholesterol is described. Its chief advantage over present procedures is in a considerable saving of time and labor involved in the preparation of large numbersof samples. The method appearsto give a more complete extraction of glyceridesand comparesfavorably with existing methods of ex...

Delivering popular web pages to the clients results in high bandwidth and high load on the web servers. A method to overcome this problem is to send these pages, requested by many users, via multicast. In this paper, we provide an analytic criterion to determine which pages to multicast, and analyze the overall saving factor as compared with a unicast delivery. The analysis is based on the well...

A simple, inexpensive, and rapid method for the determination of pregnanediol in pregnancy urine by gas liquid chromatography is described. Automatic injection of the samples into the gas chromatograph allows up to 36 samples to be run overnight thus saving valuable technical time.The method described can easily be adopted for use in a routine steroid laboratory. The results obtained by this me...

BACKGROUND Saving groups are increasingly being used to save in many developing countries. However, there is limited literature about how they can be exploited to improve maternal and newborn health. OBJECTIVES This paper describes saving practices, factors that encourage and constrain saving with saving groups, and lessons learnt while supporting communities to save through saving groups. ...
