What is BICEP 2?
Strong on broadleaf weeds and grasses but gentle to the crop, Bicep II Magnum® herbicide combines two active ingredients and effective sites of action for foundation broadleaf weed and grass control. Bicep II Magnum is a good foundation for two-pass weed control in corn and sorghum crops.
What are B modes?
B-mode (brightness mode) image, a two-dimensional ultrasound image and the most common type. B-modes, a pattern of polarized light originating from the Big Bang.
What is BICEP2?
The BICEP2 telescope, fitted with 512 cryogenic transition-edge sensors, precisely mapped the CMB emanating from a small slice of sky at a frequency of 150 GHz. The telescope detected curl-like B-mode polarization, which can be produced by a tensor field, such as the gravitational field during the era of inflation.
How do you use metolachlor?
General Information. Metolachlor controls weeds by inhibiting growth of seedling shoots. It proves effective on weeds when applied before germination; hence, it is typically applied before or immediately after planting of the crop.
What is E mode polarization?
E-polarization is often also characterized as a curl-free mode with polarization vectors that are radial around cold spots and tangential around hot spots on the sky. In contrast, B-polarization is divergence-free but has a curl: its polarization vectors have vorticity around any given point on the sky.
What are E and B-modes?
A small portion of the Cosmic Microwave Background (CMB) is polarised, and the pattern observed in the polarised fraction can be split in two components, called E-modes and B-modes. These carry very different and complementary information about both the early and the late Universe.
Did the Planck satellite find gravitational waves?
Despite earlier reports of a possible detection, a joint analysis of data from ESA’s Planck satellite and the ground-based BICEP2 and Keck Array experiments has found no conclusive evidence of primordial gravitational waves.
How much atrazine is in Lexar?
a.i./A if only applied postemergence. Note: For purposes of calculating total atrazine active ingredient applied, Lexar Herbicide contains 1.74 Ibs. a.i. atrazine plus related compounds per gallon.
What is Prefix herbicide?
Prefix Herbicide is a selective herbicide for the control or partial control of certain grass, broadleaf and sedge weeds in soybeans and cotton. Prefix Herbicide may be applied as a preplant surface, preplant incorporated, preemergence, or postemergence treatment in soybeans and as a post-directed treatment in cotton.
What is the difference between metolachlor and S-metolachlor?
S-metolachlor provides the same level of weed control at a 35 percent lower rate than generic herbicide brands containing the racemic metolachlor. Generic metolachlor herbicides are only labeled for the lower rate to preserve the reduced herbicide load benefits of S-metolachlor-containing brands.
How does the Keck Array work?
The Keck Array consists of five polarimeters, each very similar to the BICEP2 design, but using a pulse tube refrigerator rather than a large liquid helium cryogenic storage dewar . The first three started observations in the austral summer of 2010–11; another two started observing in 2012.
What is the difference between the BICEP3 and the Keck Array?
BICEP3 is also a prototype for the BICEP Array. The Keck array is being succeeded by the BICEP array, which consists of four BICEP3-like telescopes on a common mount, operating at 30/40, 95, 150 and 220/270 GHz. Installation began between the 2017 and 2018 observing seasons. It is scheduled to be fully installed by the 2020 observing season.
What is the new BICEP Array?
The Keck array is being succeeded by the BICEP array, which consists of four BICEP3-like telescopes on a common mount, operating at 30/40, 95, 150 and 220/270 GHz. Installation began between the 2017 and 2018 observing seasons.
