We report the first experimental demonstration of an electrostatic electron orbital angular momentum (OAM) sorter, which can be used to analyze OAM states electrons in a transmission microscope. verify sorter functionality for several beams possessing different superpositions states, and use it record spectra. Our current has resolution 2 units h/bar - reduced Planck constant. It is expected increase optimal 1 future via fine control sorting phase elements.
Rural and urban dichotomy is a common fact prevailing in India this modern civilization. But sometimes we also notice within an area. For instance can discuss regarding Chandannagar Municipal Corporation as city of intra dichotomy. This situated at Hugli district West Bengal share latitudinal extension from 22 °50′30″ N to °53′30″ 88 °18′30″E ° 23′30″ E . We visit infrastructural, social environmental between eastern western portion city. observe strong inequality disparity natural field two...
Genetic improvement of the cultivars jute ( Corchorus olitorius L. and capsularis L.) is needed to broaden genetic base new cultivars. All in use have been evolved through pure line selection from a few common accessions. The objective this study was evaluate diversity available cultivated species jute. evaluated by simple sequence repeat (SSR) marker loci an AFLP assay. A total 305 polymorphic products were detected analysis using 10 pairs primers Eco RI Mse I ) amplify template DNA 49...
Herein, a chromone based simple reversible fluorescent “turn-on” probe HMCP [6-(Hydroxymethyl)-N'-((6-methyl-4-oxo-4H-chromen-3-yl)methylene)picolinohydrazide] was successfully introduced to detect Al3+ over group of other coexisting metal ions in methanol at pH 7.2....

Besides, five records India apterous ovipara cajanae are also described. The status Sitobion indicum...
Abstract Five new species of aphids, Anomalosiphum indigoferae, Holotrichosiphon russellae, Matsumuraja indica, urticae and Tinocallis himalayensis are described from Darjeeling District, West Bengal. Apterous oviparous females Euceraphis chuansiensis Tao, Impatientinum impatiensae (Shinji), beside alate form Eutrichosiphum pseudopasiniae Szel. Four aphid recorded for the first time India 6 to

Chirality can appear at many length scales in nature. In this study the authors introduce planar chirality as a quantitative geometric measure of for two-dimensional objects. They apply to evaluate nanometer-sized structures with an electron microscope. employ innovative electron-optics device, orbital-angular-momentum sorter, which applies log-polar conformal mapping wave function and reaches near-optimal resolution orbital angular momentum.
Abstract Further studies on aphids from Bastera India reveal four species, Chaitophorus indicus, Greenidea neoficicola, Micromyzus granotiae, Moliitrichosiphum (Metatrtchosiphon) alni as new to science. Alate viviparous form of Amphorophora ampullatta-bengalensis Hille Ris Lambers and Basu is also described for the first time. Besides, 4 other species viz., Capitophorus archangelskii Nevsky, Macromyzus polypodicola (Takahashi), woodwardiae Macrosiphoniella hikosanensis Moritsu, are recorded...
Abstract. One new genus Indomyzus and five species sensoriatus, Aiceona paraosugii, Capitophorus himalayensis, polygoni, Tuberaphis indica along with a subspecie Uroleucon formosanus Tak., crepidis are described from the Darjeeling District, West Bengal. Five Acyrthosiphon (Microlophium) rubiformosanus (Tak.), Hyalomyzus sensoriatus (Mason), Nipponaphis machilicola Takahashi, Macrosiphum (S.) avenae akebiae Shinji Pseudaphis abyssinica H.R L. being recorded for first time India notes on some...
Abstract The hitherto unknown apterous oviparous female of Macromyzus woodwardiae (Takahashi), and alate males Aiceona litseae Basu H.R.L. Tinocallis distincta Ghosh et. al., are described. Further, Aphis spiraecola Patch male Aulacorthum (Perillaphis) perillae (Shinji) have also been described for the first time from India. Besides, sexuales Brachycaudus helichrysi (Kltb.), Macrosiphum (Sitobion) miscanthi sp., Schoutedenia lutea (v. d. Goot) reported as new to state.
