The Columbian ground squirrel (Spermophilus columbianus), Richardson ground squirrel (Spermophilus richardsoni), and blacktail prairie dog (Cynomys ludovicianus) cause millions of dollars of loss to Montana agriculture each year. Montana's ground squirrel and prairie dog control programs are based upon local organization and operation with technical assistance being provided by the Montana Depa...
In this study, the performance analysis of a 5.5 kW, 460 V, 60 Hz, 4-pole, and 3-phase squirrel- cage induction motor (IM) has been carried out by developing portable electronic circuit, design, software, independent any commercial software. The mathematical equations used in design steps preliminary main dimensions squirrel IM are realized with developed circuit. To perform calculations Nextio...
Self exited Induction generators are widely used in non conventional energy systems such as wind, micro/mini hydro, etc. The squirrel cage induction generator is simple, reliable, cheap, lightweight, ruggedness, and requires very little maintenance. This paper presents the self-excitation and modeling, steady-state, performance analysis and generating schemes of induction generators.
This paper analysis the variables needed to represent the internal dynamics of a squirrel-cage induction motor drive system. This is an important issue when automatic input/output modelling, based on learning through examples algorithms, is considered. These modelling techniques allow a precise knowledge of the drive dynamics, fundamental topic in modern control approaches, without using variab...
A series of experiments examined the ability of dopamine D3/D2 receptor agonists [(+)-(4aR,10bR)-3,4,4a,10b-tetrahydro-4-propyl-2H,5H-[1]b enzopyrano-[4,3-b]-1,4-oxazin-9-ol hydrochloride (PD 128,907), (+/-)-7-hydroxy-dipropylaminotetralin hydrobromide (7-OH-DPAT), quinpirole and bromocriptine] to produce a variety of dopaminergically mediated behaviors. The effects of these drugs with selectiv...
It is known that the squirrel monkey, marmoset, and other related New World (NW) monkeys possess three high-frequency alleles at the single X-linked photopigment locus, and that the spectral sensitivity peaks of these alleles are within those delimited by the human red and green pigment genes. The three alleles in the squirrel monkey and marmoset have been sequenced previously. In this study, t...
Due to many physiological and genetic characteristic similarities to humans, squirrel monkeys provide an ideal animal model specifically for studying malaria, and transmissible spongiform encephalopathies (Creutzfeldt-Jacob disease). While squirrel monkeys three years and older are generally considered adult subjects suitable for use in medical research studies, little is known about the functi...
MicroRNAs (miRNAs) are 19- to 25-nucleotide-long small and noncoding RNAs now well-known for their regulatory roles in gene expression through posttranscriptional and translational controls. Mammalian hibernation is a physiological process involving profound changes in set-points for food consumption, body mass and growth, body temperature, and metabolic rate in which miRNAs may play important ...
The occurrence and abundance of ®ve species of arboreal mammals in 25 rain forest fragments ranging from <1 ha to 2500 ha in area in the Anamalai Hills in south India, were examined in relation to several habitat and landscape variables. The lion-tailed macaque (Macaca silenus) was the most aected, being absent from 15 fragments while the Nilgiri langur (Trachypithecus johnii) was absent from ...
