Implications of field quantization on Ramsey interferometry are discussed and general conditions for the occurrence of interference are obtained. Interferences do not occur if the fields in two Ramsey zones have precise number of photons. However in this case it is shown how an analog of Hanbury-Brown Twiss photon-photon correlation interferometry can be used to discern a variety of interferenc...

Adults of the brown planthopper (BPH) and the whitebacked planthopper (WBPH) that migrated into Korea from China were not parasitized by the mermithid, Agamermis unka. BPH and WBPH collected from Korean rice fields were parasitized. Parasitism of BPH in the lst-3rd, 4th, and 5th instars, and adults was 31.5%, 61.5%, 66.4%, and 45.5%, respectively, whereas parasitism of the same stages of WBPH w...

Abstract Wefelscheid (Untersuchungen über Fastkörper und Fastbereiche, Habilitationsschrift, Hamburg, 1971) generalised the well-known Theorem of Artin/Schreier about characterization formally real fields and fundamental result Baer/Krull to near-fields. In last fifty years arose from a theory, which analyses entirety orderings field (E. Becker, L. Bröcker, M. Marshall et al.), as presented e.g...

In this Quick Guide, Steven Buck explains how, uniquely among the bright primary perceptual hues, yellow changes its hue when it appears dark, becoming the colour brown.

In rice cultivation, the Brown plant hopper causes damage to growth of plants by sucking cell sap and it in drying crop fields this effects on turns into yellow color later brown. order overcome kind particularly a field trial was conducted during kharif 2017 at Agricul Research Station Gangavathi assess bio-efficacy Dinotefuran 20% SG against brown Nilaparvatha lugens (Stall) paddy.

Teh ultrasound-assisted magnetic stirrer was used as an effective extraction technique for teh evaluation of total phenolic contents (TPC) and antioxidant potential of ten Pakistani brown rice cultivars. For this purpose, ultrasonic (240W frequency 50/60 Hertz) assisted magnetic stirrer coupled with three solvents methanol, ethanol, and isopropanol in pure and aqueous fractions (80:20) were...

We discuss the emergence ofW-algebras as asymptotic symmetries of higher-spin gauge theories coupled to three-dimensional Einstein gravity with a negative cosmological constant. We focus on models involving a finite number of bosonic higher-spin fields, and especially on the example provided by the coupling of a spin-3 field to gravity. It is described by a SL(3) × SL(3) Chern-Simons theory and...

Polycarpaea corymbosa (L) Lam, is a weed which belongs to Caryophyllaceae family is seen throughout India. It is distributed in tropical Asia and Australia. It is quite common in Gujarat is waste lands and in cultivated fields. It is a small, erect annual herb. Simple or branched woody at base. Stem and branches slender and faintly terete. Pale green in colour and pubescent in younger parts. Le...
