A set of blocks which can be a subset of only one t-( v, k, At) design has been termed a defining set of that design. In an earlier paper the author examined the smallest such sets of blocks for certain designs; that work is continued here for further designs. Improved lower bounds for the cardinality of a defining set are given for the affine and projective planes of order n. 1. Defining Sets:...

206 Introduetion T he small rock-dwelling cichlids of Lake Malawi are colleetively known as mbuna and, until recently, were neglected by African fishermen. Currently the mbuna are classified among ten different genera in which more than 70 species have been scientifically described.

BACKGROUND Meningococcal meningitis (MM) represents an important public health problem especially in the "meningitis belt" in Africa. Although seasonality of epidemics is well known with outbreaks usually starting in the dry season, pluri-annual cycles are still less understood and even studied. In this context, we aimed at study MM cases time series across 9 sahelo-sudanian countries to detect...

The freedom of the Deep Web offers a safe place where people can express themselves anonymously but they also can conduct illegal activities. In this paper, we present and make publicly available1 a new dataset for Darknet active domains, which we call it ”Darknet Usage Text Addresses” (DUTA). We built DUTA by sampling the Tor network during two months and manually labeled each address into 26 ...
