In this study the cleavage divisions and the ultrastructural analysis of early embryos as well as cellular organisation of infective oncosphere of the anoplocephalid cestode Mosgovoyia ctenoides are described. The early cleavage is unequal and results in the formation of three types of blastomeres: 2 large macromeres containing large electron dense granules, 3 medium-size mesomeres and several ...

ABSTRACT The Tesler matrices with hook sums (a1, a2, . . . , an) are non-negative integral upper triangular matrices, whose i diagonal element plus the sum of the entries in the arm of its (french) hook minus the sum of the entries in its leg is equal to ai for all i. In a recent paper [6], the second author expressed the Hilbert series of the Diagonal Harmonic modules as a weighted sum of the ...

Many textbooks contain material on partitions. Two standard references are [A] and [S]. A partition of a natural integer n with parts λ1, . . . , λk is a finite decreasing sequence λ = (λ1 ≥ λ2 ≥ · · · ≥ λk > 0) of natural integers λ1, . . . , λk > 0 such that n = ∑k i=1 λi. We denote by |λ| the content n of λ. Partitions are also written as sums: n = λ1 + · · ·+ λk and one uses also the (abusi...

Abstract In this article, we evaluate determinants of “block hook” matrices, which are block matrices consist hook matrices. particular, deduce that the determinant a matrix factorizes nicely. addition give combinatorial interpretation aforesaid factorization property by counting weighted paths in suitable digraph.

We present here for the first time the crystal structure of an AT-hook domain. We show the structure of an AT-hook of the ubiquitous nuclear protein HMGA1, combined with the oligonucleotide d(CGAATTAATTCG)(2), which has two potential AATT interacting groups. Interaction with only one of them is found. The structure presents analogies and significant differences with previous NMR studies: the AT...

The free vascularized fibula flap has been widely used for clavicle reconstruction. Limited evidence exists for the long-term outcome of clavicle reconstruction using the free vascularized fibula flap in adults. We report the functional and aesthetic outcome in a 52-year old man a decade after clavicle reconstruction using a free vascularized fibula flap in combination with a modified Richardso...

a r t i c l e i n f o Keywords: Celebrity presenter characteristics Hook versus linear conceptualization of characteristics Persuasion and dissuasion This study validates Rossiter and Percy's (1987) hook theory of presenter characteristics, for celebrity presenters. Firstly, by employing a product-alone control group, the study demonstrates that some celebrity-product pairings have a good fit a...

INTRODUCTION Fishing is a leisure activity for some people around the world. Accidently the fish hook can get hooked in the hand. If the hook is barbed, removal becomes difficult. We report a case of such a injury in the hand and discuss the technique for its removal with a brief review of the literature. CASE PRESENTATION A thirty-two year old male accidently suffered a fishhook injury to hi...
