We present here the 2001–2004 results of observational field studies aimed at quantifying tropical timberline climate and radial increment of Pinus hartwegii Lindl. trees on Nevado de Colima, in the middle of the North American Monsoon region. An automated weather station was installed at 3760 m a.s.l., 19834.7789N latitude, 103837.1809W longitude, within a forest where multi-century tree-ring ...

PURPOSE To evaluate the effects of bimatoprost 0.03% single treatment for 3 years on intraocular pressure (IOP) and visual field performance. METHODS We monitored the IOP of 62 patients with normal-tension glaucoma every 1-3 months. The Humphrey visual field test was performed every 6 months after treatment and the results obtained were compared to those before treatment. In addition, visual ...

BACKGROUND The purpose of this study was to evaluate the effects of topical nipradilol monotherapy for 5 years on intraocular pressure, visual field performance, and optic disk topography. METHODS Thirty patients with normal tension glaucoma were monitored for intraocular pressure every 1-3 months. A Humphrey visual field test and measurement of optic disk configuration using the Heidelberg r...

OBJECTIVES Digitized infrared segmental thermometry (DIST) is a method for measuring and recording skin surface body temperatures. The project evaluated the required length of time for patients to acclimatize their core body temperature to ambient conditions to obtain stable DIST readings. METHODS Seventeen subjects were allowed a 20-minute acclimatizing period in a temperature-controlled roo...

The two-phase ejector refrigeration cycle (TPERC) system with a two-throat nozzle ejector was investigated experimentally, and the entrainment ratio of the ejector and the COP of the system were compared with those of the ejector with Laval nozzle and its TPERC system respectively. The experimental results indicate that under the working condition of the evaporating/condensing temperatures 1°C/...

Thermoset polyimide resins are used as the polymer matrix in high temperature composites for aerospace applications such as engine shrouds. At these locations the components have to withstand high temperatures and significant vibration. A number of studies have investigated the effects of thermal exposure on mechanical properties of polyimide resins, and the effects of fatigue on thermoplastics...

A novel uncalibrated CMOS programmable temperature switch with high temperature accuracy is presented. Its threshold temperature Tth can be programmed by adjusting the ratios of width and length of the transistors. The operating principles of the temperature switch circuit is theoretically explained. A floating gate neural MOS circuit is designed to compensate automatically the threshold temper...

One of the main elements of dendrochronological standardization is removing the biological trend, i.e. the progressive decline of ring width along a cross-sectional radius that is caused by the corresponding increase in stem size and tree age over time. The ‘‘conservative’’ option for removing this biological trend is to fit a modified negative exponential curve (or a straight line with slope #...

Abstract Human-induced actions aggravate forest degradation and result in carbon emissions. Increment of emission rises land surface temperature (LST) contributes to climate change. The aim this study was assess the impacts cover change on stocks, emissions LST over period 1992–2022 using geospatial techniques Sor watershed, Western Ethiopia. results revealed that declined by 336.6 km2 due expa...
