Invariants of the plane-stress elasticity stiffness matrix [Q] play a key role in composite design, as they simplify design processes. Multiple invariants have been proposed independently past, such ‘trace’ Tr=trace([Q]) by Tsai and Melo or U1, U4 U5, which are often used context lamination parameters. The present paper presents parametric description rotation-independent (invariant) linear com...

Buyers and sellers in developing countries are often restricted from accessing distant markets by asymmetric price information costly searches. Electronic marketplaces can reduce transaction costs improve market performance. This study uses monthly panel data 2000 to 2017 applies a fixed effects approach using Driscoll Kraay standard errors address spatial temporal correlations provide empirica...

Many subtypes of acute lymphoblastic leukemia (ALL) are associated with specific chromosomal rearrangements. The complex translocation t(9;14;14), a variant of the translocation (14;14)(q11;q32), is a rare but recurrent chromosomal abnormality involving the immunoglobulin heavy-chain (IGH) and CCAAT enhancer-binding protein (CEBPE) genes in B-lineage ALL (B-ALL) and may represent a new B-ALL su...

Cytogenetic studies were performed on three patients with chronic T cell leukemia and on one patient with T cell lymphoma. One of the patients had leukemic cells derived from a suppressor T cell clone, another expressed OKT3, 4, and 8, and cells of the other two were derived from a helper T cell clone. All patients had an abnormal karyotype in peripheral blood or bone marrow cultured with or wi...

Chronic myeloid leukaemia (CML) is characterized by the presence of the BCR-ABL fusion gene, usually in association with the t(9;22)(q34;q11) translocation. We report here the identification and cloning of a rare variant translocation, t(4;22)(q12;q11), in two patients with a CML-like myeloproliferative disease (MPD). RT-PCR indicated that both patients were negative for BCR-ABL, but FISH analy...

We have detected and cloned two rearrangements in the T-cell receptor alpha locus from a clone of somatic cell hybrids carrying a t(14;14)(q11;q32) chromosomal translocation derived from an ataxia telangiectasia patient with T-cell chronic lymphocytic leukemia. The T-cell clone carrying the t(14;14) chromosomal translocation was known to be present for greater than 10 years before the onset of ...

Maternal uniparental disomy for chromosome 7 (UPD7) may present with a characteristic phenotype reminiscent of Silver-Russell syndrome (SRS). Previous studies have suggested that approximately 10% of SRS patients have maternal UPD7. We describe a girl with a mos47,XX,+mar/46,XX karyotype associated with the features of SRS. Chromosome painting using a chromosome 7 specific probe pool showed tha...
