Design and control of an axial-flux machine for a wide flux-weakening operation region
(2009)This paper describes the strategy to design and control an axial-flux (AxF) surface-mounted permanent-magnet machine for achieving a wide flux-weakening (FW) operating region. By using a slotted stator with fractional-slot ... -
Analysis of a second-order sliding-mode algorithm in presence of input delays
(2006)In this note, a double integrator system under the action of a second-order sliding-mode control algorithm is considered, and the resulting closed-loop behavior in presence of an input delay is analysed. Due to the delay, ... -
Effect and repeatability of Ascaridia galli egg output in cockerels following a single low dose infection
(Elsevier, 2001)Three groups of caged 20 Tetra-SL cockerels aged 1 day were orally infected with 30, 60 or 125 embryonated Ascaridia galli eggs. After 11, 12 and 13 weeks, faecal egg counts (FECs) were determined. All birds were slaughtered ... -
Saugverhalten von Lamas (Lama glama) = Suckling behaviour of Llamas (Lama glama)
(Schlütersche Verlagsgesellschaft, 2003)In the present study the suckling behaviour of six Ilama crias was analysed. A total of 3398 suckling bouts were observed and evaluated. The crias mostly suckled in a reverse parallel position with no side preference. The ... -
Response of two breeds of chickens to Ascaridia galli infections from two geographic sources
(Elsevier, 2007)Comparative resistance to different isolates of Ascaridia galli was investigated in a local chicken breed from Jordan (LC) and in the Lohmann LSL white chicken (LW) strain. In two trials, birds of LC and LW were inoculated ... -
Rasse- und Geschlechtsunterschiede im Temperament von Kälbern in Mutterkuhhaltung
(Schlütersche Verlagsgesellschaft, 2001)Behavioural traits related to temperament were studied in German Angus (Aberdeen Angus x German dual purpose breeds) and German Simmental cattle. Temperament was defined as the animal's behavioural response to handling. ... -
Genetic resistance to gastrointestinal nematode parasites in Rhön sheep following natural infection
(Elsevier, 2001)Genetic parameters of resistance to gastrointestinal nematodes were estimated in Rhön sheep, a local sheep breed in Germany. In the first year, a total of 131 lambs (born between January and February 1998) from five rams ... -
Influence of sex on the resistance of sheep lambs to an experimental Haemonchus contortus infection
(Schlütersche Verlagsgesellschaft, 2006)36 intact male and 69 female lambs of two breeds (n = 63 Merinoland; n = 42 Rhön) aged 12 weeks were orally infected with 5000 infective-stage larvae, L3, of the nematode Haemonchus contortus. After 4 and 8 weeks faecal ... -
Differences in recombination rates on chromosome 23 between German Angus and German Simmental and breed specific linkage mapping
(Wiley: 12 months, 2003)Five paternal half sib families of German Angus (GA) (n = 428) and six of German Simmental (GS) (n = 378) including dams were genotyped with 11 microsatellites (INRA132, RM033, BM1815, BM1258, BOLA-DRB1, BM1818, BM1905, ... -
Pattern of Eimeria oocyst output and repeatability in naturally infected suckling Rhön lambs
(Wiley, 2001)The faeces of 14 Rhön lambs were examined every second day between 7 and 99 days of age for the presence of Eimeria oocysts. Eimeria absata, E. bakuensis, E. faurei, E. granulosa, E. intricata, E. ovinoidalis, E. pallida, ...
