The tissue polarity pathway is required for the establishment of epithelial polarity in a variety of vertebrate and invertebrate organs. Core tissue polarity proteins act in a dynamically regulated complex to direct the polarization of the Drosophila eye. We report the identification and characterization of bedraggled (bdg), a novel gene that regulates one output of the tissue polarity pathway-...

Abstract Palm oil mill effluent (POME) contains very high organic compounds that must be treated before being discharged into the environment. Pond technology has been widely used for treatment of POME; however, it requires a huge area land. Down-flow hanging sponge (DHS) reactor shown pollutant removal efficiency, less energy, and land requirement. This study aimed to investigate performance s...

This paper studies lower bounds for classical multicolor Ramsey numbers, first by giving a short overview of past results, and then by presenting several general constructions establishing new lower bounds for many diagonal and off-diagonal multicolor Ramsey numbers. In particular, we improve several lower bounds for Rk(4) and Rk(5) for some small k, including 415 ≤ R3(5), 634 ≤ R4(4), 2721 ≤ R...

We establish a homeomorphism between the moduli space Aord 4,k (R) of ordered k-tuples (H1, . . . ,Hk) of 2-dimensional linear subspaces Hi ⊂ R4 (mod GL4(R)) and the quotient by simultaneous conjugation of a certain open subset (GLk−3 2 ) ∗ ⊂ (GL2(R))k−3. For k = 4, this leads to an explicit computation of the moduli space A4,4(R) of central 2-arrangements in R4 mod GL4(R) and its subspace A2,4...

We fully compute the N = 1 supersymmetrization of the fourth power of the Weyl tensor in d = 4 x-space with the auxiliary fields. In a previous paper, we showed that their elimination requires an infinite number of terms; we explicitely compute those terms to order κ (three loop). We also write, in superspace notation, all the possible N = 1 actions, in four dimensions, that contain pure R term...

The effect of pelleting fodder on voluntary feed intake and digestibility in sheep was tested with sorghum straw cowpea haulm two forms (chopped granulated). Twenty-four (24) sheep, 18 to 24 months old, Djallonké breed were divided into 4 groups 6 following a random complete block device four (04) treatments as follows: R1= 50% chopped + haulms, R2 = Granulated 1 (50% haulms), R3 maize bran R4 ...

Abstract The prolonged start-up time and low total nitrogen removal of anammox hinder its full-scale application. Herein, application nano-zerovalent iron strength magnetic field in sole combination to abbreviate the period long-term process stability was carried out. reactor’s with only (R3) 34 days, saving 43.3% compared control. increase efficiency over control 43.7% during period. However, ...

In this article we study the tangent cones at first time singularity of a Lagrangian mean curvature flow. If the initial compact submanifold Σ0 is Lagrangian and almost calibrated by ReΩ in a Calabi-Yau n-fold (M,Ω), and T > 0 is the first blow-up time of the mean curvature flow, then the tangent cone of the mean curvature flow at a singular point (X0, T ) is a stationary Lagrangian integer mul...

Various examples of Malament-Hogarth (hereafter, M-H) spacetimes are given in Hogarth (1992), but the following artificial example from Earman and Norton (1993) is perhaps the simplest. Start with Minkowski spacetime (R4, η) and choose a scalar field Ω on M such that Ω=1 outside a compact set C⊂M and Ω tends rapidly to infinity as a point r∈C is approached. The spacetime (R4-r, Ω2η), depicted i...
