Peach (Prunus persica L. Batsch.) is produced in most areas of Iran, where flowering is hindered by temperature. Using plant growth regulators to delay bloom is a suggestive measure to avoid frost damage. The objective of this study was to determine the effects of methyl jasmonate (MJ) and salicylic acid (SA) on peach bloom delay and yield. This study evaluated the applications of MJ 0 (contro...
Pulsed laser methods for OH generation and detection were used to study atmospheric degradation reactions for three important biogenic gases: OH + isoprene (R1); OH + -pinene (R2); and OH + -3-carene (R3). Gas-phase rate coefficients were characterised by non-Arrhenius kinetics for all three reactions. For (R1), k1(241-356 K) = (1.93 0.08)10 15 exp{(466 12)/T} cmmolecule s was determined...
Photodynamic therapy (PDT) uses light to activate a photosensitizer to achieve localized tumor control. In this study, PDT mediated by a second-generation photosensitizer, palladium-bacteriopheophorbide WST09 (Tookad) was investigated as an alternative therapy for prostate cancer. Normal canine prostate was used as the animal model. PDT was performed by irradiating the surgically exposed prosta...
This paper describes two simple techniques that can greatly improve navigation and motion control of nonholonomic robots based on range sensor data. The first technique enhances sensory information by re-using recent sensor data through coordinate transformation, whereas the second compensates for errors due to long control cycle times by forward projection through the kinematic model of the ro...
