This paper presents a stochastic modeling framework for store-and-forward packet routing protocols in Wireless Body Area Networks (WBAN). A prototype WBAN has been constructed for experimentally characterizing and capturing on-body topology disconnections in the presence of ultra short range radio links, unpredictable RF attenuation, and human postural mobility. Delay modeling techniques for ev...

SYNTHESIS OF (k) - 6,8-DIHYDROXY-3- ISOPROPYL-7-METHYLISOCHROMAN

The title isochroman ( 8 ) was synthesized as a suitable substrate for acetoxylation studies leading to an intermediate of type (4), expected to afford, on condensation with diketen, the fungal metabolite "rotiorin" type linear product (1). Cyclocondensation of alcohol (6), obtained by the reduction of ketone (5) with paraform in the presence of anhydrous aluminum chloride afforded the dim...

Crystal structure of 5,7-dihydroxy-3-methylcoumarin.

coumarin derivatives are of great interest in view of their sensitizing abilities in photodynamic effects and their wide occurrence in the plant kingdom. Umbelliferone, 7hydroxycoumarin, which has been known as a strongly fluorescing compound, also exhibits chemiluminescence.1 On the other hand, 7-hydroxy-4-methyl coumarin2 (Fig. 1-(I))has been applied in laser gain studies. The title compound ...

Effects of i.v. and oral 1,25-dihydroxy-22-oxavitamin D(3) on secondary hyperparathyroidism in dogs with chronic renal failure.

BACKGROUND 1,25-Dihydroxyvitamin D(3) (1,25(OH)(2)D(3), calcitriol) has been used for the treatment of secondary hyperparathyroidism (2HPT) associated with chronic renal failure (CRF). However, hypercalcaemia frequently precludes the administration of ideal doses of 1,25(OH)(2)D(3). 1,25-Dihydroxy-22-oxavitamin D(3) (22-oxacalcitriol, OCT) is an analogue of 1,25(OH)(2)D(3) with less calcaemic a...
