in order to study on effect of plant density and nitrogen on yield and yield components of visia faba (faba bean), the experimental design was implemented by randomized complete block with three replications at 2010- 2011 in lahijan. the experimental factors were three plant density (25×25 cm, 35×35 cm and 45×45 cm) and four nitrogen fertilizer (0, 20, 40, 60 kg ha-1). in this experiment, featu...

Sub-Doppler excitation spectroscopy in a collimated cold supersonic beam of 5% NO seeded in argon has been performed with a spectral resolution down to 10 MHz for four vibronic bands within the perturbed B ?X A system of NO . The rotational temperature of about 15 K achieved by adiabatic cooling allows the separation of closely lying vibronic bands which overlap in absorption spectra ...

This reflective contribution tells the story of a veteran public sector crisis management (CM) researcher’s 35-year journey with educating students and CM practitioners, It offers preliminary insights about how pandemic experience might – should induce significant rethink educators conceptualize nature crises challenges governments agencies face in coping them.

Abstract Although chickens can improve the chemical properties of soil through deposition excreta, their effects on macrofauna are poorly known. This work assessed grazing indigenous laying hens two agroecosystems in Portugal: an organic horticultural field and a conventional orchard. At field, were used to control weeds results compared with those other weed treatments: mechanical (rototiller)...

Eight plant densities (8.8, 9.5, 10.4, 11.4, 17.6, 19.1, 20.8, and 22.9 plants m ) in 2001–2002 and 12 plant densities (8.8, 9.5, 10.4, 11.4, 12.7, 14.3, 17.6, 19.1, 20.8, 22.9, 25.4, and 28.6 plants m ) in 2002–2003 were evaluated on growth and fruit yield of ‘Sweet Charlie’ strawberry (Fragaria ananassa Duch.) grown in a passively ventilated greenhouse. Plant densities were derived by varying...

Resonant holographic interferometry and dye-laser-resonance-absorption photography have been utilized to investigate the expansion of the laser ablation plumes produced by a KrF excimer laser beam (248 nm) focused onto an aluminum target (-0.1 cm’, 2-6 J/cm’). Plume expansion was studied in vacuum and in background argon gas pressures of 14 mTorr, 52 mTorr, 210 mTorr, 1 Torr, and 35 Ton: The ex...

Historically, wetlands along the St. Johns River, Florida, were dominated by herbaceous marshes. However, in the last 50 years many areas transformed to shrub-dominated wetlands, at the same time a system of levees and canals was constructed to control flooding. We tested the role of water management in controlling Carolina willow (Salix caroliniana), a native shrub that accounts for most of th...

Background and Purpose. Lymphoedema is a serious complication following limb salvage for extremity soft tissue sarcomas (STSs) for which little is known. We aimed to evaluate its incidence, its, severity and its associated risk factors. Material and Method. Patient and tumor characteristics, treatment modalities and complications and functional outcomes (MSTS 1987, TESS), and lymphoedema severi...
