the experiment was conducted to determine the effects of different photoperiods and darkness on the growth and survival of juvenile catla catla in the laboratory for 90 days. fishes were divided into four aquaria (10 fish per aquarium), and subjected to different photoperiod regimes of 8 hours light: 16 hours dark (8l:16d), 16 hours light: 8 hours dark (16l:8d), continuous light (24l:0d) and co...

The Brunn–Minkowski Theorem asserts that μd(A+B)1/d ≥ μd(A) + μd(B) 1/d for convex bodies A,B ⊆ R , where μd denotes the d-dimensional Lebesgue measure. It is well known that equality holds if and only if A and B are homothetic, but few characterizations of equality in other related bounds are known. Let H be a hyperplane. Bonnesen later strengthened this bound by showing μd(A+B)≥ (M1/(d−1) +N1...

in order to estimate responses of growth rate and growth hormone of clarias gariepinus to stocking density, fish (initial weight 30.71 ± 0.89 g) were stocked in 120-l tanks at densities of 35, 65, 95, and 125 kg/m3 for 60 days. on day 30 and 60, the fish growth rates were measured, pituitary growth hormone (gh) mrna levels and serum gh concentrations were examined by real-time qpcr and elisa te...

Suppose f,g are homogeneous polynomials of degree d defining smooth hypersurfaces Xf=V(f)⊂Pm−1 and Xg=V(g)⊂Pn−1. Then the sum f g defines a hypersurface X=V(f⊕g)⊂Pm+n−1 with an action μd scaling variables. Motivated by work Orlov, we construct semi-orthogonal decomposition derived category coherent sheaves on [X∕μd] provided d≥max{m,n}.

L et I be an ideal, homogeneous with respect to the usual grading, in a polynomial ring R = k[x0, . . . , xn] in n+ 1 variables (over an algebraically closed field k). Denote the graded component of I of degree d by Id, and likewise the k-vector space of homogeneous forms of R of degree d by Rd. Since I is a graded R-module, we have k-linear maps μd,i : Id ⊗ Ri → Id+i given for each i and d by ...

tuning recombinant protein expression is an approach which can be successfully employed for increasing the yield of recombinant protein production in high cell density cultures. on the other hand, most of the previous results reported the optimization induction conditions during batch and continuous culture of recombinant e. coli, and consequently fed-batch culture have received less attention....

In recent years, a body of research into “condition numbers” for convex optimization has been developed, aimed at capturing the intuitive notion of problem behavior. This research has been shown to be relevant in studying the efficiency of algorithms (including interior-point algorithms) for convex optimization as well as other behavioral characteristics of these problems such as problem geomet...
