UNLABELLED This study reports the development of a loop-mediated isothermal amplification (LAMP) reaction for the detection of Pythium myriotylum. The primer set targeting the ITS sequence of P. myriotylum worked most efficiently at 60°C and allowed the detection of P. myriotylum DNA within 30 min by fluorescence monitoring using a real-time PCR instrument.(More)
Results of X-Ray Diffraction (XRD) analysis, Triple Oxygen Isotope analysis and Scanning Electron Microscopic (SEM) studies are presented for stone fragments recovered from the North Central Province of Sri Lanka following a witnessed fireball event on 29 December 2012. The existence of numerous nitrogen depleted highly carbonaceous fossilized biological(More)
We show that the Polonnaruwa stones that were collected on 29 December 2012 following a witnessed fireball, in which we found biological structures, do not possess properties that are consistent with fulgurites on the basis of X-ray diffraction studies, and other data. The existence of distinct diatom frustules fused into the rock matrix makes recent(More)
This article discusses motors for compressors in domestic air conditioners, an area in which there is a strong demand for high efficiency and also reports the results of the efficiency improvement and productivity of a new core structure. An innovative core structure and manufacturing method boosts efficiency of permanent-magnet motors. This article(More)
Three decades ago the first convincing evidence of microbial fossils in carbonaceous chondrites was discovered and reported by Hans Dieter Pflug and his collaborators. In addition to morphology, other data, notably laser mass spectroscopy, confirmed the identification of such structures as putative bacterial fossils. Balloon-borne cryosampling of the(More)
The ingress of micrometeorites of cometary origin with densities below ~ 1 g cm-3 into the Earth could average at least 5 tonne per day. Although much of this is burnt upon entry through the atmosphere as meteors, a non-trivial fraction (~10%) which have sizes of ~ 1 m could end up in the form of Polonnaruwa-type meteorites that have mostly gone unnoticed.
We report on the physical, chemical and mineral properties of a series of stone fragments recovered from the North Central Province of Sri Lanka following a witnessed fireball event on 29 December 2012. The stones exhibit highly porous poikilitic textures comprising of isotropic silica-rich/plagioclase-like hosts. Inclusions range in size and shape from(More)
We have developed a wide area intruder detection surveillance system which was delivered to the Japanese market last summer. This technology is known as MELWATCH which stands for MELco WATCH(to keep lookout). It has been installed at several sites in Japan. MELWATCH is composed of a pair of sensor cables, a sensor unit and an intrusion detection terminal.(More)
Preliminary SEM/EDAX studies of the Tissint meteorite shows projections of interior spherical globules rich in C and O. Such concentrations of carbonaceous material in a matrix of mineral grains poses a mystery if biological processes are excluded. They are consistent with remnants of biological structures, thus supporting earlier similar claims for the(More)
