This study was carried out to control Johne’s disease (JD) without interfering with tuberculosis (TB)control programme. A dairy herd (n>1500 heads) was used over a period of 6 years, from 1994 to 1999 forthis investigation. The herd had a history of heavy infection with Mycobacterium avium paratuberculosis(MAP) with culling rates of 1.5 and 5%, in 1991 and 1995, respectively. The mean annual lo...

The utilization of VoIP (Voice over IP) in UMTS networks requires the establishment of adequated rules in order to maximize the efficiency of transmission over the air interface. Here we will describe a technique, based on the reduction of voice packet overhead, with the objective of minimizing the power expended during a typical conversation.

Existing microstructure literature cannot explain the empirical evidence that bid-ask spreads can decrease with information asymmetry and ignores either information asymmetry or inventory risks. We develop a market making model that highlights the asset pricing impact of market makers’ capability of making offsetting trades in markets where both information asymmetry and inventory risk are sign...

In this paper, a multicast scheme for UMTS which only requires insignificant modifications in the current UMTS network infrastructure is analyzed. We analytically present the multicast routing mechanism behind our scheme as well as the multicast group management functionality of it. Furthermore, we present an evaluation of our scheme in terms of its performance. The critical parameters for the ...

This study extends previous studies, which examined the intellectual structure, major themes, and reference disciplines of decision support systems (DSS) over the last two decades (1970-1995). Factor analysis of an author cocitation matrix over the period of 1995 through 1999 extracted five major areas of DSS research (group support systems, design/foundations, model management, implementation,...

OBJECTIVE Demographic studies in various industrialised countries have shown a decline in male births in the latter half of the 20th century from the expected ratio of 0.515 (males/total). This study analyses trends in this ratio over the period 1890 to 1995 in Malta, and also analyses this ratio for Western European countries for the period 1990-1995. DESIGN Births subdivided by sex were obt...

BACKGROUND After an epidemic rise in Australian young male suicide rates over the 1970s to 1990s, the period following the implementation of the original National Youth Suicide Prevention Strategy (NYSPS) in 1995 saw substantial declines in suicide in young men. AIMS To investigate whether areas with locally targeted suicide prevention activity implemented after 1995 experienced lower rates o...
