ISOTOPE ANALYSIS METHOD BY USE OF RAMAN EFFECTPURPOSE:To measure the concentration of isotope in sample by the use of a Raman effect in which Raman scattering intensity is proportional to the concentration of isotope in the sample.KATOU OONORI...
A source of quantum noise in a non-linear optical medium is the coupling of photons with thermal phonons, called the Raman effect. This noise source sets the lower limit of squeezing in the polarisation variables for ultrashort pulses. Increasing the soliton pulse width reduces the coupling betwe...
With a growing body of research associating livestock agriculture with faster global warming, higher health costs and greater land requirements, a drastic shift towards plant-based diets is often suggested as an effective all-round solution. Implicitly, this argument is predicated on the assumption tha...
The use of language is innately political, often a vehicle of cultural identity and the basis for nation building. Here, we examine language choice and tweeting activity of Ukrainian citizens based on 4,453,341 geo-tagged tweets from 62,712 users before
Due to sessile nature of plants, they face a variety of biotic and abiotic stresses during their life cycle. These stresses are responsible for disturbed cellular processes that adversely affect their growth and yield. To cope with these stresses, plants
The Raman effect, using the signal associated with the core and the flexible alkyl chains, was used to probe the Fredericksz transition in the limit of small deformations. The data for the cores show good agreement with data published elsewhere. Odd-even effects were found and, in the case ...
Portland clinker production consists essentially in the burning of material with defined composition in a rotary kiln at temperatures around 1450 掳C. The ... D Gastaldi,E Boccaleri,F Canonico - 《Journal of Raman Spectroscopy》 被引量: 11发表: 2010年 Experiences with the design of large size...
Since the late 1950’s when proton n. m. r. spectroscopy was first used in organic natural products studies the technique has increasingly contributed to the rapid advancement of this important area of chemistry. Although the potential utility of 13C n.
Human activities, especially conversion and degradation of habitats, are causing global biodiversity declines. How local ecological assemblages are responding is less clear—a concern given their importance for many ecosystem functions and services. We a
The wood specimens were secured in a wooden rig and periodically rotated to ensure equal exposure of surface to the path of the flowing sediments. The flow velocity allowed for the greatest possible effect on the sticks, which were left in the water for 2 weeks, 70 hours of which ...
