چکیده
Sugarcane is one of the most important field crops grown in the tropics and sub-tropics. Conventional and biotechnological research inputs have contributed in solving some of the constraints limiting crop productivity. However, limitations such as complex genome, narrow genetic base, poor fertility, susceptibility to biotic and abiotic stresses and long duration to breed elite cultivars, hinder crop improvement programmes. Sugarcane, thus, is a suitable candidate for application of plant biotechnology and genetic engineering tools. In this direction, we have been working towards employing in vitro culture system combined with radiation induced mutagenesis in the improvement of sugarcane. Several radiation induced mutants with agronomically desirable traits were isolated and evaluated under field conditions, besides studying abiotic stress responses using biochemical, physiological and molecular tools. This article describes the developments in the in vitro culture systems and related biotechnologies that are evolving as novel strategies in the recent years for use in sugarcane improvement.

مطالعات اخیر نشان داده که میراگر جرمی غیرفعال می تواند پاسخ تغییرمکان حداکثر سازه های نامتقارن رابه طور مناسبی کاهش دهد. ولی در اکثر سازه ها کاهش همزمان شتاب و تغییرمکان دو لبه از اهمیت بالاییبرخوردار است. در این مقاله کنترل لرزه ای ساختمانهای نامتقارن یک، چهار و هشت طبقه با خصوصیاتمختلف پیچشی با استفاده از میراگر جرمی با مشخصات و موقعیتهای مختلف مورد مطاله قرار گرفت. کاهشحداکثر تغییرمکان و شتا...
متن کاملPMD induced transmission penalties in polarization multiplexed transmission
In this paper, we investigate for the first time chromatic dispersion and nonlinearity tolerances in the presence of polarization-mode dispersion (PMD) for polarization-multiplexed (POLMUX) 2 × 10-Gb/s nonreturn-to-zero (NRZ) transmission. In polarization-multiplexing, the interaction between fiber nonlinearity and PMD can lower the nonlinear tolerance beyond the tolerances evident when conside...
متن کاملPreconditioning repetitive transcranial magnetic stimulation of premotor cortex can reduce but not enhance short-term facilitation of primary motor cortex.
Short trains of suprathreshold 5-Hz repetitive transcranial magnetic stimulation (rTMS) over primary motor cortex (M1) evoke motor potentials (MEPs) in hand muscles that progressively increase in amplitude via a mechanism that is thought to be similar to short-term potentiation described in animal preparations. Long trains of subthreshold rTMS over dorsal premotor cortex (PMd) are known to affe...
متن کاملDigital backpropagation accounting for polarization-mode dispersion.
Digital backpropagation (DBP) is a promising digital-domain technique to mitigate Kerr-induced nonlinear interference. While it successfully removes deterministic signal-signal interactions, the performance of ideal DBP is limited by stochastic effects, such as polarization-mode dispersion (PMD). In this paper, we consider an ideal full-field DBP implementation and modify it to additionally acc...
متن کاملCombining PMD and Stereo camera for Motion Estimation of a Mobile Robot
This paper introduces an improvement to the 6D motion estimation solution by combining the Photonic Mixer Device (PMD) and Stereo Camera. The main feature of the stereo camera is the higher resolution of the 2D image compared to the one from the PMD camera. Whereas the depth information derived from a PMD is usually far superior to the result from a stereo camera. This work hence proposes a com...
