We describe a method to frequency narrow multielement high-power diode bars. Using a commercial 60-W, 49-element, 1-cm-long diode array bar at 795 nm running at 45 W, we narrow the linewidth from 1000 to 64 GHz with only a loss of 33% in output power. The resulting laser light is well suited for spin-exchange optical pumping of noble gas nuclei.

to evaluate the effects of different dry period lengths on milk yield, milk composition, reproductive performance and energy balance in dairy cows, 30 holstein breeds (average 270 days pregnant) were made use of in a randomized complete block design. cows were assigned to three treatments (60, 45 and 30 days of dry period) and two blocks as based on parity (either first lactation or multifariou...

Peanut (Arachis hypogaea L.) seeds were germinated to investigate the effect of fermentation period oak tree sawdust on germination viability and seedling characteristics. Its rate, weight, length, total vigor index assessed. The sown in fermented for 0, 30, 45, 60 days. rates significantly different. 45-day produced heaviest biomass weight (4.6 g) with longest true leaf (1.7 cm) hypocotyl (3.4...

Honokiol has shown chemopreventive effects in chemically-induced and UVB-induced skin cancer in mice. In this investigation, we assessed the time-effects of a topical low dose of honokiol (30 μg), and then the effects of different honokiol doses (30, 45, and 60 μg) on a UVB-induced skin cancer model to find an optimal dose and time for desirable chemopreventive effects. UVB radiation (30 mJ/cm(...

Introduction: The cumulative mass M(>ve) of impact ejecta with velocities higher than ve (hereafter we call this cumulative mass-velocity (CMV) distribution) is one of the most important parameters for understanding quantitatively the morphology of ejecta blankets around craters or the surface evolution of planetary bodies. A scaling law on CMV distribution has been formulated based on the data...

Background: Pearlmillet is conventionally cultivated by farmers either broadcasting or uniform row spacing of 45 cm where it difficult to accommodate an intercrop. Modified planting pattern provides additional space for intercrop component as well harvest better solar energy in the system. Methods: The field experiment was conducted Department Agronomy, Tamil Nadu Agricultural University, Coimb...
