Many clinically important or mechanistically interesting inhibitors react with enzymes by a branched pathway in which inactivation of the enzyme and formation of product are competing reactions. The steady-state kinetics for this pathway [Waley (1980) Biochem. J. 185, 771-773] gave equations for progress curves that were cumbersome. A convenient linear plot is now described. The time (t1/2) for...
Previously, it has been suggested that insect gas exchange cycle frequency (fC) is mass independent, making insects different from most other animals where periods typically scale as mass-0.25. However, the claim for insects is based on studies of only a few closely related taxa encompassing a relatively small size range. Moreover, it is not known whether the type of gas exchange pattern (disco...
Chromatic induction is observed whenever the perceived colour of a target surface shifts towards the hue of a neighbouring surface. Some vivid manifestations may be seen in a white background where thin coloured lines have been drawn (assimilation) or when lines of different colours are collinear (neon effect) or adjacent (watercolour) to each other. This study examines a particular colour indu...
Forest filtering is a well-known and efficient method for diminishing atmospheric pollutant (such as SO42- and Cl-) inputs to soil and water; however, the filtering efficiencies of forests vary depending on the regional vegetation and climate. The rainy area of West China has suffered from heavy rainfall and human activity, which has potentially resulted in large amounts of sulfur and chlorine ...
Bromopolystyrene beads with diameters of up to 600 microm have been derivatized completely, via bromine-magnesium exchange and interception with electrophiles, to yield high quality solid-supported reagents, scavengers and solid supports for use in diversity-oriented synthesis.
This paper presents a dual-modular-redundancy and dual-level error-interception based triple-node-upset (TNU) tolerant latch design (namely DDETT) for safety-critical applications. The DDETT comprises two parallel single-node-upset self-recoverable cells to store values three C-elements intercept errors. Both of the are constructed from triple mutually-feeding-back 2-input C-elements, feed inte...
nowadays, in the modern wars, radars have faced with many threats. therefore, low probability of interception (lpi) capability is considered as an important factor in military radars. on the other hand, research on the interception of their signals is started and so far several methods are presented for detection of these signals. by using of time-frequency techniques, we can estimate signal pa...
intercropping is a correct method of management for crop production and leads to improvement of resource absorption and use by plants. in order to evaluate light interception and some characteristics of canopy in monocropping and intercropping of maize (zea mays l.) and faba bean (vicia faba l.) under climatic conditions of tabriz, a field experiment was conducted in 2006-2007 at the research s...
We study the dynamics of a system of hard-core particles sliding downwards on a one-dimensional fluctuating interface, which in a special case can be mapped to the problem of a passive scalar advected by a Burgers fluid. Driven by the surface fluctuations, the particles show a tendency to cluster, but the hard-core interaction prevents collapse. We use numerical simulations to measure the autoc...
In the framework of semihard (kT factorization) QCD approach, we consider the differential cross sections of D∗± meson production at HERA. The consideration is based on BFKL and CCFM gluon distributions. We find that in the case of BFKL LO gluon distribution the theoretical results are sensitive to the Pomeron intercept parameter ∆. We present a comparison of the theoretical results with availa...
