This study seeks to investigate the effect of restricted feeding regimes at different rate on growth performance of Clarias gariepinus using static and flow through system. Fingerlings were divided into six batches for each systems with the first and second batch fed at 5% body weight (BW) every day and every other day respectively, the third and fourth batch were fed 10% BW every day and every...

sociopolitical developments have deep connections with the growth and expansion of the middle class. one of the features of modernizing societies is emergence and growth of middle class.egypt, a great arab country, over the past two centuries has a long experience of modernization as a result of which it has been a ground for social developments. besides the islamist groups, other new currents,...

This study builds an income distribution and growth model within a simple multi-sectoral Kaleckian framework. The model has heterogeneous features in each sector in that the responses of saving and investment to changes in macroeconomic performance differ sectorally, and there are also different sectoral shares of saving and investment. We consider the determinants that establish the economic g...

In situ studies on the growth and evolution of platinum nanocrystals in solution were carried out using synchrotron-based X-ray diffraction (XRD) techniques. Ex situ low- and high-resolution transmission electron microscopy (TEM) were used to investigate the nanocrystal morphologies through the different growth stages. In a reaction with low precursor concentration, both XRD and TEM results sho...

1. Introduction. The standard theory of the tearing-mode evolution identifies three stages. The first is the linear stage described by the Furth–Killeen–Rosenbluth (FKR) theory [1]. During this stage, the island width W grows exponentially in time until it reaches the width of the resistive dissipation layer, ℓ η ∝ η 2/5 ∆ ′1/5 , where η is the resistivity and ∆ ′ is the instability parameter [...

this study investigates the effects of the government effectiveness and financial development indices on economic growth in d-8 countries over the period 1996-2012, by applying the panel smooth transition regression (pstr) model. for this purpose, we use non-linear least squares (nls) method for estimation of model. the estimation results reject the linearity hypothesis, and estimate two regime...

We investigate the low-temperature growth of crystalline thin silicon films: epitaxial, twinned, and polycrystalline, by hot-wire chemical vapor deposition HWCVD . Using Raman spectroscopy, spectroscopic ellipsometry, and atomic force microscopy, we find the relationship between surface roughness evolution and i the substrate temperature 230–350 °C and ii the hydrogen dilution ratio H2/SiH4=0–4...

The "law of the minimum" (Liebig's law) states that usually one nutrient restricts the maximum quantity of biomass that can be produced within a system, whereas all other nutrients are in excess. This general rule has been applied also to the growth of microorganisms, e.g., by adjusting the relative concentrations of the individual nutrients in growth media such that one of them, in the case of...

In this research, non-linear inflationary dynamics based on the concept of missing money is studied using the threshold autoregressive models based on seasonal data of the time interval (1990:04-2016:07) for the economy of Iran. The finding of the research shows that simple and Divisia liquidity growth variables are determined as threshold variables, and inflation reacts to changes in the growt...

A theoretical framework has been developed for the study of the nonlinear gravitational (g-) mode of a line-tied flux tube near marginal stability. The theory is based on an expansion using two small parameters, ∼ |ξ|/Leq 1, and n−1 ∼ k‖/k⊥ 1, with ξ denoting the plasma displacement, Leq the characteristic equilibrium scale, k‖ and k⊥ the dominant wavenumber of perturbation parallel and perpend...
