Abstract Adoption of the new biofuel crop carinata ( Brassica A. Braun) in southeastern United States will largely hinge on sound agronomic recommendations that can be economically incorporated into and are compatible with existing rotations. Timing weed control is crucial for yield protection long-term seedbank management, but predictive emergence models have not been as widely studied winter ...

The chamomile species of Anthemis triumfettii (L.) All is one of important medicinal plant belong to Compositae family and it grows as wild species in Zagros and Alborz Mountains, Iran. The aim of this study was to evaluation of morphological and phenological traits and their relationships with essential oil. Seeds of seven accessions were sown in jiffy pots and transferred to field using rando...

Weed plants characteristic for potato and hop fields have not been considered in the past as potential hosts that could transmit and lead to spreading of potato spindle tuber (PSTVd) and hop stunt (HSVd) viroids, respectively. To gain insight into this problem, we biolistically inoculated these weed plants with viroid populations either as RNA or as cDNA. New potential viroid host species, coll...

AIM/BACKGROUND The development of resistance to synthetic drugs by target organisms is a major challenge facing medicine, yet locked within plants are phytochemicals used in herbal medicine (especially in the Arabian Peninsula) that may find application in this regard. In pursuit of unlocking these "hidden treasures," the methanol extracts of leaves, aerial parts, fruits, and resins of 17 plant...

With large-capacity FPGAs, such as the Xilinx Virtex family, complex systems can now be constructed from reconfigurable hardware, and sophisticated designs are more easily implemented through C-language hardware compilers, such as Handel-C [1]. However, improved language support is not enough, as effective system design needs structured methods and high-level design support, which a language by...

In this paper we present a design case study using Handel-C—a recently developed programming language for compilation of high-level programs directly into FPGA hardware. The design is an 8-bit RISC microcontroller core with 33 instructions, prescaler and a programmable timer. Handel-C was used throughout the entire design and debugging flow. The RISC microcontroller design was implemented in on...
