This research has been conducted to establish a wheel-point device and evaluate its efficiency (precision, accuracy and time) with respect to the estimation of canopy percent in a pilot Artemisia stand in Khabr region of Baft, Kerman province, Iran in 2015. Several transects with different lengths (30, 60, 90, 120, 150 and 180 m) were established using the randomized sampling block with 5 repli...

The key parameters of pressure relief pre-splitting blasting technology (PRPBT) contribute to the implementation effect goaf-side entry by roof cutting (GSERC). This study is an attempt design including height, angle, spacing between boreholes, charge structure and sealing length using theoretical analysis, numerical simulation field implementation. basic quality index main 666.27, combined wit...

Tulip is one of the most important flowers to precocity. Treatment of tulip bulbs with gibberellic acid reduces the forcing period in the greenhouse resulting energy saving and reduces the tulip’s physiological disorders. This study carried out about three tulip cultivars includes ‘Lacourtine’, ‘Yokohama’ and ‘Red Favourite’. The results showed that gibberellic acid reduced significantly stem l...

the objectives of this study were to determine the age, growth, mortality and exploitation of a commercially important fish of northeastern mediterranean sea, mullus barbatus from the karatas coast of iskenderun bay during september 2002 and april 2003. a total of 212 specimens of red mullet were collected by monthly sampling using traditional bottom trawl net by commercial vessel (coskun reis,...

Adhesion was measured repeatedly between opposed molecularly thin layers of perfluoropoly(alkyl ether)s on mica, with particular attention to the dependence of the adhesion on chain-end functionality and chain length of the polymer. The polymer layers were kept in contact for specified times that differed by 4 orders of magnitude (0.01-500 s) and then unloaded (separated) at rates that varied b...

High-efficiency pressure-retaining sampling technology for obtaining seabed sediments is required studying marine geological history, the survival principles of microorganisms, and evolution earth life. In this paper, a novel submersible-mounted sampler capable collecting pressure-retained samples at full ocean depth designed. The structure scheme first presented, including unit, pressure-compe...

The establishment of a regional historical landslide inventory plays an indispensable role in assessment and prevention. In this study, based on the Google Earth platform, ancient landslides Hualong County, Qinghai Province was established. includes 3517 with individual areas ranging from 2354.6 m2 to 12.44 km2. dominant characteristics include elevation 2600–2800 m, slope 10–20°, aspects SW, W...

BACKGROUND Diagnosis of short QT syndrome (SQTS) remains difficult in case of borderline QT values as often found in normal populations. Whether some shortening of refractory periods (RP) may help in differentiating SQTS from normal subjects is unknown. METHODS AND RESULTS Atrial and right ventricular RP at the apex and right ventricular outflow tract as determined during standard electrophys...

Beachrocks are generally mapped on the coastline surface and/or in a low depth subtidal zone coastlines and cemented chiefly by carbonate material. Their outcrops may vary from tenth of meters to kilometers length. Along Epirus coast, Greece, beachrocks laying for more than ten kilometers. In present work, we used Unmanned Aerial Vehicles (UAVs), situ sampling, Geographical Information System (...

in this research, in order to develop new relationships with reasonable accuracy for estimation of the ‎submerged hydraulic jump characteristics, a study has been conducted experimentally. experiments have ‎been done in a rectangular channel with a length of 9 m, a width of 0.5 m and a depth of 0.45 m. froude ‎numbers in these tests range from 3.5 to 11.5 and between submergence ratios of 0.1 t...
