The freshwater spiny eel, Macrognathus pancalus is an inland water teleost fish commonly known as barred or striped spiny eel found in Asia. The sampling areas were selected which are spatially and geographically different and characterized by different environmental conditions in order to elucidation of ecotype. A total 345 specimens were collected from the sampling sites during January 2008...

Background: FishBase.org is an on-line database of fish related data that has been cited over 1500 times in the fisheries literature. Length-weight relationships in fish traditionally employ the model, W(L) = aL b , where L is length and W is weight. Parameters a and b are catalogued by FishBase for a large number of sources and species. FishBase.org detects outliers in a plot of log(a) vs. b t...

The aim of this study is to examine the relationship between length, weight, condition factor (K), and relative (Kn) Mystus tengara (Hamilton, 1822), with special emphasis on seasonal variation growth patterns, productivity, stocks, conservation in two distinct ecosystems: pond river. results demonstrate that species did not strictly adhere predicted cube law had allometric patterns throughout ...

the development of seminal and lateral root system plays a major role in plant access to water and nutrients under abiotic stress, especially salinity. in order to understand the relation between root growth responsesand shoot physiological indices oftwo bread wheat cultivars contrasting in salt tolerance (kavir and shiraz), a greenhouse experiment was conducted with two salinity levels (0 and ...

We propose a new approach to calculate perturbatively the effects of a particular deformed Heisenberg algebra on energy spectrum. We use this method to calculate the harmonic oscillator spectrum and find that corrections are in agreement with a previous calculation. Then, we apply this approach to obtain the hydrogen atom spectrum and we find that splittings of degenerate energy levels appear. ...

It is widely accepted that an interaction exists between masticatory muscle function and craniofacial growth. In adults, correlations have been found between facial dimensions and jaw-muscle cross-sectional area, and between facial dimensions and masseter muscle thickness. Little is known about growth of the human masticatory muscles and its relation with facial dimensions at different ages. In...

A simple algorithm is introduced for computing the run length distribution of a monitoring scheme combining a Shewhart chart with an Exponentially Weighted Moving Average control chart. The algorithm is based on the numerical approximation of the integral equations and integral recurrence relations related to the run-length distribution. In particular, a modified Clenshaw-Curtis quadrature rule...

First, a new framework describing the transfer matrices for the two dimensional run length constrained arrays (codes) is introduced, and some important properties of the transfer matrices ( 1) m T m  are derived in this framework. Then, using these properties, it is shown that the numbers ( , ) ( , 1) N m n m n  of the two dimensional binary arrays satisfying the (1, )  run length constraint...
