Canine influenza virus (CIV) is a newly identified, highly contagious respiratory pathogen in dogs. Recent studies indicate that avian-origin H3N2 CIV are circulating in Chinese dogs. To investigate the effects of a two-amino acid (2-aa) insertion naturally occurring at the distal end of the neuraminidase (NA) stalk found in Chinese isolates since 2010 on virus replication and virulence, we res...

Adsorption and desorption of phosphorus (P) and nitrogen (N) by stalk residues may influence the concentrations of P and N in runoff. A laboratory study was conducted to measure the effects of P and N constituents in solution on adsorption and desorption of P and N by corn, soybean, and wheat stalk residues. Experimental variables included type of stalk material (corn, soybean, and wheat), inor...

The Caulobacter crescentus cell extension known as a stalk represents an unusual bacterial morphology. C. crescentus produces stalks under multiple nutrient conditions, but the length of the stalk is increased in response to phosphate starvation. However, the exact function of the stalk is not known, nor is it known how much stalk biogenesis or function is conserved with other stalked bacteria....

in other to evaluation of morphological and phenological traits of 24 populations, from four species chamomile of the genus of anthemis, an experiment were carried out using randomized completely blocks design (rcbd) in three replications in alborz research station in karaj, iran during 2011-12. 13 traits including: length and width of canopy diameter, plant height, number of flower, shoot fres...

The experiment was conducted in the lath house for college of Agriculture, University Sumer autumn season 2019-2018, to study effect adding humic acid at a concentration (0,3,6) ml / liter and spraying with PROSOL concentrations (0, 2.5 5) g on plant growth flowering traits. As chrysanthemum seedlings were brought from nurseries Al-Rifai district age about month uniform height transferred 7 kg ...

r primordia of length 0-5-1-4 mm, (iii) stalks of open hydranths (polarized, the stolon grows out of the cut basal end). (b) Immediate differentiation of a polyp. Shown by (i) stalk primordia longer than 1-7 mm "' and some between 1-4 and 1-7 mm, (ii) bulbs greater than 0-28 mm diameter (i.e. had reached contractile stage), (iii) bulb primordia of all sizes having a 'stalk' longer than 0-35 mm;...

the main object of this study was to evaluate the effect of tillage and crop residues management of barley (hordeum vulgare l.) on quantification and qualification yield of corn (zea mays l.). treatments were laid out in complete randomized block design with seven treatments and three replications and include (1) fire of straw and stubble, plow, disc and furrower (2) gathering and transfer of s...

A model to predict the distribution of harvest dates in an Easter lily crop was validated using data from several locations. Plants were individually harvested (i.e. removed from the greenhouse for shipping) when flowers on a plant reached a minimum flower bud length. A computer decision-support system called LilyDate was developed to allow the model to be used to optimize greenhouse temperatur...
