Romero, Ethel M. (Universidad Nacional de la Plata, La Plata, Argentina), and Rodolfo M. Brenner. Fatty acids synthesized from hexadecane by Pseudomonas aeruginosa. J. Bacteriol. 91:183-188. 1966.-The lipids extracted from Pseudomonas aeruginosa incubated with hexadecane in a mineral medium were separated into a nonpolar and three polar fractions by thin-layer chromatography. The fatty acid com...

A series of pseudosymmetrical structures of formula K10(M2OnF11-n)3X (M = V and Nb, n = 2, X = (F2Cl)1/3, Br, Br4/2,I4/2; M = Mo, n = 4, X = Cl, Br4/2, I4/2) illustrates generation of polar structures with the use of Λ-shaped basic building units (BBUs). For a compound to belong to a polar space group, dipole moments of individual species must be partially aligned. Incorporation of d(0) early t...

We introduce the notion of uniform number of a graph. The  uniform number of a connected graph $G$ is the least cardinality of a nonempty subset $M$ of the vertex set of $G$ for which the function $f_M: M^crightarrow mathcal{P}(X) - {emptyset}$ defined as $f_M(x) = {D(x, y): y in M}$ is a constant function, where $D(x, y)$ is the detour distance between $x$ and $y$ in $G$ and $mathcal{P}(X)$ ...

Pressure drop of fully developed, laminar, incompressible flow in smooth mini and microchannels of arbitrary cross-section is investigated. A compact approximate model is proposed that predicts the pressure drop for a wide variety of shapes. The model is only a function of geometrical parameters of the cross-section, i.e., area, perimeter, and polar moment of inertia. The proposed model is comp...

[1] A series of 24 h mesoscale simulations (of 10 km horizontal and 400 m vertical resolution) are performed to examine the characteristics and forcing of gravity waves (GWs) relative to planetary waves (PWs) during the 2008–2009 major stratospheric sudden warming (SSW). Just prior to SSW occurrence, widespread westward propagating GWs are found along the vortex’s edge and associated predominan...

We introduce a block polar quantization (BPQ) procedure that minimizes a weighted distortion for a set of sinusoids representing one block of a signal. The minimization is done under a resolution constraint for the entire signal block. BPQ outperforms rectangular quantization, strictly polar quantization, and unrestricted polar quantization (UPQ) both when assuming the Cartesian coordinates of ...

Polar coded grayscale image communication over additive white Gaussian noise (AWGN) channels using orthogonal frequency division multiplexing (OFDM) system is demonstrated in this paper. The OFDM technique is effective multicarrier technique used in the high-speed transmission system. Polar codes are recently applied to the binary memoryless channel and binary erasure channels for achieving nea...
