Evaluation of the CERES models in different production regions of the Czech Republic

open access: yesPlant, Soil and Environment, 2002
The main goal of this work was to calibrate and evaluate the CERES-Barley and CERES-Wheat crop models. The experimental fields used for the model evaluation are situated in three different production regions (maize, sugar beet and potato main growing ...

The nicotinamide hypothesis revisited—plant defense signaling integrating PARP, nicotinamide, nicotinic acid, epigenetics, and glutathione

open access: yesFEBS Letters, EarlyView.
Nicotinamide (NIC) and nicotinic acid (NIA) are proposed as stress signaling compounds in plants. Oxidative stress may lead to single strand breaks (SSB) in DNA, which activate poly(ADP‐ribose) polymerase (PARP). NIC and NIA are then formed from NAD. NIC and NIA can promote epigenetic changes leading to the expression of defense genes specific for the ...

About models of knowledge production

open access: yesВестник Воронежского государственного университета: Серия экономика и управление, 2004
Production of knowledge as a special product, which is mostly described by qualitative characteristics, is studying. Because of that peculiarity the apparatus of «difficulty of goal achievement», factors of «fuzziness» and qualitative functions, which ...

Excess Higgs Production in Neutralino Decays

open access: yes, 2012
The ATLAS and CMS experiments have recently claimed discovery of a Higgs boson-like particle at ~5 sigma confidence and are beginning to test the Standard Model predictions for its production and decay. In a variety of supersymmetric models, a neutralino

A working model for cytoplasmic assembly of H/ACA snoRNPs

open access: yesFEBS Letters, EarlyView.
Dyskerin is the component of nuclear H/ACA ribonucleoproteins (RNPs) endowed with pseudouridine synthase catalytic activity. Two isoforms of human dyskerin have been characterized: the abundant Iso1, mainly nuclear, and the shorter Iso3, mainly cytoplasmic but occasionally imported into nuclei.

A new approach of proration-injection allocation for water-flooding mature oilfields

open access: yesPetroleum, 2015
This paper presents a new method of injection-production allocation estimation for water-flooding mature oilfields. The suggested approach is based on logistic growth rate functions and several type-curve matching methods.
