The endogenous adaptation of economic agents, that may adjust their trade network in response to infection rates, can have the perverse effect increasing overall systemic infectiveness a disease. We study dynamical model over two geographically distinct but interacting markets, better understand theoretically mechanism at play. also discuss analogies with 2018 African Swine Fever, and provide e...

We provide an attack to (EC)DSA digital signature built upon Coppersmith’s method. We prove that, if a, k are the private and ephemeral key, respectively, of the (EC)DSA scheme and (k−1mod q)a < 0.262 · q, then we can efficiently find a.

Bluetongue has only been isolated as yet from species of biting midges of the genus Culicoides, initially from Culicoides pallidipennis in South Africa by du Toit (1944) and then from C. variipennis in the United States of America by Price and Hardy (1954). More recently it has been isolated from C . pallidipennis, C . milnei and C . tororoensis in Kenya (Walker and Davies 1971), and from C. pa...

Studies throughout the western United States have shown that livestock can degrade riparian vegetation and stream channels and produce sediment, pathogen, and nutrient loading. This study at the Sierra Foothill Research and Extension Center is the first to focus on effects of livestock grazing on hardwood rangeland springs and associated riparian resources. Cattle grazing treatments at three in...

56 Low-yielding catchments with ephemeral streams provide a stern test of the capability of conceptual catchment models for 57 predicting the hydrologic response of the natural landscape. Sustained periods of little or no flow mean that the information content 58 of the streamflow time-series for parameter estimation is limited. During periods with no streamflow, such ephemeral catchments 59 al...

malaria is the most serious parasitic disease and one of the oldest recorded diseases in the world. because of the resistance of malaria parasites to current drugs, it is necessary to discover new antiplasmodial drugs. traditional medicine is one of the important sources of new antiplasmodial drugs.in this study, twenty methanolic extracts from different parts of sixteen medicinal plants used i...

1. Florfenicol, proposed for treatment of bovine respiratory disease also called shipping fever or transit fever, is a wide spectrum, synthetic antibacterial substance. It is structurally related to D (-)threo chloramphenicol (CAP), but differs from it in two fundamental aspects : firstly, presence of a pmethyl sulfonyl group instead of the p-nitro group, secondly, presence of fluorine atom ins...

Some Borrelia species associated with Lyme disease bind the complement-regulatory protein factor H (fH), a process that may aid in immune evasion. In this report we demonstrate that some Borrelia species associated with relapsing fever bind fH, but not those associated with avian borreliosis and epizootic bovine abortion. Cell-bound fH was also found to mediate cleavage of exogenously supplied ...

The stability of some viruses and methods of virus inactivation in liquid manure are reviewed. The authors discuss experimental data on the stability of foot and mouth disease virus, classical swine fever virus, Aujeszky's disease virus, African swine fever virus, swine influenza virus, porcine paramyxovirus, bovine virus diarrhoea virus and transmissible gastroenteritis of pigs virus. Recommen...
