We modelled the population phenology of the diamondback moth (DBM), Plutella xylostella (L.) (Yponomeutidae) with a simple degree day model implemented using DYMEX, a population dynamics modelling program. Predicted and observed developmental periods of DBM reared under field conditions during the months of October 1999 to February 2000 at Forthside Research Station, Tasmania (which is in the t...

Brucellosis is an important public health problem in Peru. We evaluated 48 human Brucella melitensis biotype 1 strains from Peru between 2000 and 2006. MICs of isolates to doxycycline, azithromycin, gentamicin, rifampin, ciprofloxacin, and trimethoprim-sulfamethoxazole were determined by the Etest method. All isolates were sensitive to tested drugs during the periods of testing. Relapses did no...

The Ghodaghodi Lake Complex is a Ramsar site, Nepal’s first bird sanctuary, and has significant ecological economic values. lake complex in the western part of lowland Terai region. Numerous studies indicate relation between normalized difference vegetation index (NDVI), land use, cover with plant diversity. However, association terrestrial diversity NDVI unknown but important implications due ...

Early adolescence represents a particularly vulnerable period of development during which young people are susceptible to establishing lifelong behavior patterns associated with poor life, health, and educational outcomes (McGee & Williams, 2000; Mohay & Forbes, 2009; Morgan & Todd, 2009; Schumacher & Kurz, 2000). Previous research demonstrates older adolescents and young adults often experienc...

OBJECTIVES This report provides State-specific birth rates for teenagers for 1991 and 2000, and the percent change between the time periods. METHODS Tabular and graphical description of trends in teenage birth rates by age group for each State and territory. RESULTS Birth rates for teenagers 15-19 years declined significantly in all States, the Virgin Islands and Guam, between 1991 and 2000...

BACKGROUND Understanding the causes and timing of death in extremely premature infants may guide research efforts and inform the counseling of families. METHODS We analyzed prospectively collected data on 6075 deaths among 22,248 live births, with gestational ages of 22 0/7 to 28 6/7 weeks, among infants born in study hospitals within the National Institute of Child Health and Human Developme...

This paper contains a surprisingly large amount of material and indeed can serve as an introduction to some of ideas and methods of singular perturbation theory. The work done in this area during the periods 1984–2000 and 2000–2005 has already been surveyed in 2002 and 2007 but our main objective is to produce a collection of important research articles of physical significance. In this paper, ...

Vereeck and Mühl (2000) distinguish four periods within the waiting time between conflict and court decision: the negotiation time between parties; the procedural time to prepare the trial; the waiting time before the actual start of the trial; and the time of the trial itself. They argue that while data on court delay often include the last three periods, only the third can be considered as ge...

Investigating the dynamic responses of high rise structures under the effect of siesmic ground motion is extremely important for the proper analysis and design of multitoried structures. Since the presence of infilled walls strongly influences the behaviour of frame systems in multistoried buildings, there is an increased need for developing guidelines for the analysis and design of infilled fr...

i o a Reconstructions of lake-water salinity at decadal resolution for the last 2000 yr are compared among three lakes in North Dakota to infer regional patterns of drought. The intersite comparisons are used to distinguish local variation in climate or hydrology from regional patterns of change. At one lake, diatom-inferred salinity and lake-water Mg/Ca inferred from ostracode shell chemistry ...
