conditional monitoring is prerequisite to prevent severe damage or falling down the trees. problems such as trunk decays, reduces trees resistance against wind and floods. in this study, a mathematical modeling technique is being selected to determine the trees strength against such events. finally, an applicable model for safety factor was created by having numeral (dimensions of crown and tru...

The coeliac trunk and superior mesenteric artery are the anterior visceral branches of the abdominal aorta. The anatomical variations of these arteries are due to development of the anterior splanchnic arteries. A case of coeliacomesenteric trunk was reported in this study which was observed in a 72-year-old male cadaver during the routine dissection. This trunk with a diameter of 13.98 mm is o...

2 The aim of this study was to establish threshold TGR and MDS values which could be 3 used in regulated deficit irrigation in future work. Three irrigation treatments were 4 performed during three seasons in a 37 year-old table olive orchard in Seville (Spain). 5 Control treatment was irrigated with 125% of the crop evapotranspiration. Regulated 6 deficit irrigation (RDI) treatments were perfo...

A unique sensing system is described using an ultrasonic transducer for measuring tree trunk diameters in the orchard. Trunk diameters were calculated from the time it took sound waves to travel from the transducer to the trunk and back to the sensor. The device was calibrated with objects ranging in diameter from 1.6 (0.63 inch) to 19.0 cm (7.5 inches). The distance between the transducer and ...

in order to determine the effect of irrigation interval and mulch on growth of olive an experiment was carried out in dallaho olive research station at sarepole. a split plot experiment was used based on a completely randomized design with three replications and two factors (mulch and irrigation interval). each experiment unit consists of 4 trees. land preparation was done in february 2005 in a...

Although anatomical properties and vessel variations of the celiac trunk are well explored in the literature, there is not so much information on the arterial diameters, and this data is important for surgical procedures and angiographic examinations. The aim of this study was to investigate properties of the celiac trunk in humans by using anatomical dissection. Ninety cadavers were dissected ...

Crotches were cut out of red maple (Acer rubrum), callery pear (Pyrus calleryana), and sawtooth oak (Quercus acutissima) trees (2.5”-7” d.b.h.) and then pulled apart in an engineering testing machine to identify physical parameters correlated with crotch strength. Parameters measured included the diameter of the branch and of the trunk above and below the crotch, angle of the branch and branch ...

Background The celiac artery, celiac axis or celiac trunk is the first major abdominal branch of the aorta. Anatomic variations and accessory vessels have been reported with variable percentages. The purpose of this study was to report the pattern of the celiac trunk and its anatomic variations in a sample of Mexican population. Methods Celiac trunk dissection was performed in 140 fresh cadav...
