It is hypothesized that labor availability and related low levels of demand for women in agricultural work explain the high incidence of nuclear family formation in some Caribbean slave societies, as well as occasional high birth rates. Three paired comparisons, reflecting differing levels of labor supply, are examine: The Leewards and the Bahamas; Martinique and Barbados; and Cuba and Jamaica....

In 2003, Augot et al. introduced the Fast Syndrome-Based hash family (in short FSB), which follows the generic construction of Merkle-Damg̊ard and is based on the syndrome decoding problem. In 2007, Finiasz et al. proposed an improved version of FSB. In this work, we propose a new efficient hash function, which incorporates the ideas of FSB and the sponge construction introduced by Bertoni et al...

Health[1] Health[1]Bacteria [2]Children's health [3]illness [4]immune system [5]Stress [6]Viruses [7]Norway [8] Forskning.no [9] High levels of stress in a family can undermine a child?s immune system, making it easier for viruses and bacteria to do their worst. Our immune system protects us from bacteria and viruses. But intense or long-lasting psychological stress can have a negative effect o...

Fimbrial adhesins that mediate attachment to host cells are produced by most virulent Escherichia coli isolates. These virulence factors play an important role in the initial stages of bacterial colonization and also in determination of the host and tissue specificity. Isolates belonging to serotype O78 are known to cause a large variety of clinical syndromes in farm animals and humans and have...

A new species of the family Alphaflexiviridae provisionally named alfalfa virus S (AVS) was discovered in alfalfa samples originating from Sudan. A complete nucleotide sequence of the viral genome consisting of 8,349 nucleotides excluding the 3' poly(A) tail was determined by high throughput sequencing (HTS) on an Illumina platform. NCBI BLAST searches revealed that the virus shares the greates...

Recently we have discovered an IgG degrading enzyme of the endemic pig pathogen S. suis designated IgdE that is highly specific for porcine IgG. This protease is the founding member of a novel cysteine protease family assigned C113 in the MEROPS peptidase database. Bioinformatical analyses revealed putative members of the IgdE protease family in eight other Streptococcus species. The genes of t...

From now on X denotes a set and S denotes a family of subsets of X. Now we state the propositions: (1) Let us consider sets X1, X2, a family S1 of subsets of X1, and a family S2 of subsets of X2. Then {a×b, where a is an element of S1, b is an element of S2 : a ∈ S1 and b ∈ S2} = {s, where s is a subset of X1 ×X2 : there exist sets a, b such that a ∈ S1 and b ∈ S2 and s = a × b}. Proof: {a × b,...

This paper considers the robust strict positive real (SPR) problem for a family of plants of the form G(s; q) = N(s; q n)D ?1 (s; q d)?, where N(s; q n) and D(s; q d) are multiaane in uncertain parameters q n and q d , respectively , and > 0. In the discrete-time setting, this problem plays an important role in digital quantiza-tion. Several results are presented. First, we prove that this plan...
