I review different methods devised to derive the age of the Galactic Disk, namely the Radio-active Decay (RD), the Cool White Dwarfs Luminosity Function (CWDLF), old open clusters (OOC) and the Color Magnitude Diagram (CMD) of the stars in the solar vicinity. I argue that the disk is likely to be 8-10 Gyr old. Since the bulk of globulars has an age around 13 Gyrs, the possibility emerges that t...

While odontogenic keratocysts (OKC) are fairly common and well-known, orthokeratinized cysts (OOCs) quite rare accounting for less than 1% of cysts. The entity is characterized by the presence a predominant lining. OOC much aggressive as compared to OKC simple enucleation discerned adequate treatment with minimal chances recurrence. present case report describes an extensive that involved most ...

New constructions of 3-dimensional optical orthogonal codes are presented. In each case the codes have ideal autocorrelation λa = 0, and cross correlation of λc = 1. All codes produced are demonstrated to be optimal. The constructions utilize a particular automorphism (a Singer cycle) of PG(k,q), the finite projective geometry of dimension k over the field of order q, or its affine analogue in ...

We present new constructions for (n, w, λ) optical orthogonal codes (OOC) using techniques from finite projective geometry. In one case codewords correspond to (q − 1)-arcs contained in Baer subspaces (and, in general, kth-root subspaces) of a projective space. In the other construction, we use sublines isomorphic to PG(1, q) lying in a projective plane isomorphic to PG(1, qk), k > 1. Our const...

Early-onset primary dystonia is an inherited disorder characterized by involuntary twisting, repetitive movements and abnormal postures. It has recently been demonstrated that the DYT1 gene is the most relevant gene associated with primary generalized dystonia. The DYT1 gene product is a 332-aminoacid long protein, termed TorsinA, whose function is still not clear. Based on the results obtained...

Zinc(II) complexes with dangling functional organic groups were synthesized by reaction of zinc acetate with a series of bifunctional p-substituted benzene derivatives (a combination of carboxylate, oximate, amino, β-ketoimine, and salicylaldime groups). Selective coordination to carboxylate groups was observed when the second functional group was an oxime or β-ketoimine group. When the second ...

To accommodate the explosive packet-based data traffic in WDM networks, intelligent optical routing and switching are required in optical transport networks. Optical multiprotocol label switching networks emerged to meet this demand. In this paper, different schemes for implementing an OMPLS network are introduced. An optical MPLS network using OOC/wavelengths as labels is proposed. Based on an...

In the present study, crystal structures of non-chelating EDTA molecules and their non-chelation salts in a zwitterionic state, along with EDTA-chelates alkali alkaline earth metals, were searched overviewed. 25 EDTA, zwitterions ethylenediammonium-diacetate diacetic acid HOOC-CH2-(-OOC-CH2-)NH+-CH2-CH2-NH+(-CH2-COO-)-CH2-COOH (ethylenediammonium-tetraace­tic (HOOC-CH2-)2NH+-CH2-CH2-NH+(-CH2-CO...
