We consider a single stock point for a repairable item. The repairable item is a critical component that is used in a fleet of technical systems such as trains, planes or manufacturing equipment. A number of spare repairables is purchased at the same time as the technical systems they support. Demand for those items is a Markov modulated Poisson process of which the underlying Markov process ca...

The study investigates the effect of temperature on the infectivity of two entomopathogenic nematodes, viz. Steinernema sp. and Heterorhabditis indica, locally isolated from Mizoram, northeastern India, using last instar larvae of greater wax moth, Galleria mellonella, as an insect host. Two hundred infective juveniles/larva of wax moth were exposed to different temperatures, viz. 10, 15, 20, 2...

PURPOSE To evaluate the reproducibility of water drinking test (WDT) performed at different times of the day, in primary open angle glaucoma (POAG) patients and normal individuals. METHODS Fifteen patients with POAG and 30 normal individuals underwent three WDTs at different times of the day (7 AM, 12 PM, and 5 PM) on 3 different days. Test results in POAG patients and normal individuals were...

BACKGROUND Sensory abnormalities are a key feature of Complex Regional Pain Syndrome (CRPS). In order to characterise these changes in patients suffering from acute or chronic CRPS I, we used Quantitative Sensory Testing (QST) in comparison to an age and gender matched control group. METHODS 61 patients presenting with CRPS I of the upper extremity and 56 healthy subjects were prospectively a...

Purpose: To describe the methods of performing water drinking test (WDT) and its applications in glaucoma management.
 Methods: This review is based on pertinent publications retrieved by a selective search PubMed, supplemented further articles chosen authors.
 Results: Intraocular pressure (IOP) changes throughout day. IOP peak has been identified as risk factor onset progression. WD...

Mulberry (Morus species) leaf is the sole food for monophagous silkworms, Bombyx mori L. Abiotic stresses such as drought, salinity, and high temperature, significantly decrease mulberry productivity and post-harvest water loss from leaves influence silkworm growth and cocoon yield. Leaf surface properties regulate direct water loss through the cuticular layer. Leaf surface waxes, contribute fo...

The activity of a wax ester hydrolase in the cotyledons of jojoba (Simmondsia chinensis) seedlings increased drastically during germination, parallel to the development of the gluconeogenic process. The enzyme at its peak of development was obtained in association with the wax body membrane, and its properties were studied. It had an optimal activity at alkaline pH (8.5-9). The apparent K(m) va...

An improved process for slip casting ceramic articles that does not employ parting agents and affords the casting of complete, detailed, precision articles that do not possess parting lines. A wax pattern for a shell mold is provided, and an aqueous mixture of a calcium sulfate-bonded investment material is applied as a coating to the wax pattern. The coated wax pattern is then dried, followed ...

It is well documented that most bituminous binders contain crystallisable material. This fraction, often referred to as paraffinic or natural wax, associated with the bitumen’s origin and has an influence on its rheological performance. In literature, Differential Scanning Calorimetry (DSC) primary technique used determine melting crystallisation behaviour of this waxy fraction. However, in bit...

Deepwater operations in subsea production systems can be critically affected during transient events, such as shutdown periods, because of the formation of hydrates and/or wax deposits (see figure 1). Such formations/deposits can completely block production pipelines, thus requiring different technological solutions to restart production [1, 2]. In fact, during shutdown periods the fluid looses...
