for cage culture. Species which have been researched and successfully reared in cages in the southeastern region of the U.S. include: catfish, trout, tilapia, striped bass, red drum, bluegill sunfish, crappie, and carp. Other species may be suitable for cage culture but research has lagged behind other aquaculture research in recent years. Interest in cage culture has been revived as an alterna...

Since 1998 a lots of European Internet Service Providers (ISP) started to provide internet access freely. Why does a profit maximizing operator adopts this pricing policy? A consumer who wants to surf on the net needs to buy two services: the access from the ISP and the connection from the Telephone Operator. Since the two services are complements, the price of one service creates a negative ex...

The paper addresses comprehensible proof presentation for teaching and learning that can be provided by an automated proof planner that is a component of the proof development environment mega. Starting from empirically discovered requirements for the comprehen-sibility of proofs we show that, given a proof plan representation of a proof, the problem of automatically presenting a mathematical p...

A fuzzy metric is a function of the form X×X 3 (p, q)→F Fpq ∈ ∆, where ∆ is the set of all distance distribution functions, and in many cases F generates a metrizable uniformity. Starting from this fundamental property, we present several metric-like functions determined by fuzzy metrics and we emphasize their role in getting and proving fixed point theorems for different types of contractions....

Alphaviruses are arthropod-borne viruses and are predominantly transmitted via mosquito vectors. This vector preference by alphaviruses raises the important question of the determinants that contribute to vector competence. There are several tissue barriers of the mosquito that the virus must overcome in order to establish a productive infection. Of importance are the midgut, basal lamina and t...

The International Society for Computational Biology, ISCB, organizes the largest event in the field of computational biology and bioinformatics, namely the annual international conference on Intelligent Systems for Molecular Biology, the ISMB. This year at ISMB 2012 in Long Beach, ISCB celebrated the 20th anniversary of its flagship meeting. ISCB is a young, lean and efficient society that aspi...

For medical directors, keeping up with the medical literature means not only staying clinically abreast of developments in medicine, but also appraising morbidity and mortality data for their insurance implications. One of the obstacles to morbidity and mortality data analysis, whether formal (mortality abstract preparation) or informal (simply estimating risk or general prognosis), is the abse...

We discuss two algorithms suitable for constructive utility planning using both actions and observations, which are based on iterative plan modification instead of n-step plan generation. We have analysed runtime costs and solution quality both theoretically and on a set of examples. For most situations we analysed, our algorithms perform better than conventional plan generation algorithms usin...

The availability of high performance broadband services from the home will allow a growing number of organisations to offer teleworking as an employee work practice. Teleworking delivers cost savings, improved productivity and provides a recruitment policy to attract and retain personnel. Information security is one of the management considerations necessary before an effective organisational t...

The increasing emphasis on management responsibilities and audit led us to investigate the state of surgical notes in our hospital. Twelve criteria were evaluated regarding information that should be contained in the notes and the absence of this important information was documented. Deficiencies were revealed in all criteria selected. Until hospital patients files are well kept and maintained,...
