A method is described whereby amyloplasts from immature barley (Hordeum distichum L.) endosperm could be separated into two populations of large and small amyloplasts at all stages of development. The small amyloplasts had more amylopectin than the large at early stages, but by 60 days after anthesis, the large had the greater proportion of amylopectin. Starch synthetase activity was associated...

The basis for the investigations on diffraction is provided by a large and interesting set of new experimental data. Indeed, the phenomenon of “hard” diffraction, where a hard probe has been proven to be consistent with a diffractive process, came first as an experimental surprise both at hadronhadron (Spp̄S, 88’, Tevatron 95’) and lepton-hadron (HERA, 94’) colliders. It is thus to be remarked t...

Two new species, Ectmetopterus mishmiensis sp. nov. from Arunachal Pradesh and E. nandiensis sp. nov. from Karnataka, India are described. Documentation is provided to substantiate that both new species feed on the grass Paspalum (Poaceae). The genus is recorded for the first time from India. Descriptions of the new species are provided, along with digital images of the genitalia, dorsal habitu...

Neutrinoless tau-lepton decays into either three leptons (τ − → ℓ − 1 ℓ2ℓ3) or one lepton and one K 0 S meson(τ − → ℓ − K 0 S) where lepton ℓ means either an electron or muon, have been searched for using 48.6 fb −1 of data collected with the Belle detector at the KEKB e + e − collider. No evidence for candidate decays are found in any channel. Therefore we set 90% confidence level upper limits...

In a recent paper, eight semileptonic parameters were defined to specify the most general Lorentz-invariant spin correlation functions for tau semileptonic decays. The parameters were physically defined in terms of tau-decay partial-width intensities for polarized final states. This paper studies how these parameters can be simply measured at a tau/charm factory with longitudinally polarized be...

The aim of the study was to determine which weed species had a significant effect on reduction maize yields, so that it could be determined should controlled and not controlled. research carried out using descriptive method dry land in Mumbul Sari Village, Bayan, North Lombok. Collecting data population growth weeds plants, sample plots measuring 1 m2 placed at 10 points by random sampling. Par...
