We address two central problems causing a breakdown between planning and plan execution in robots. The first is the difficulty in reliably maintaining an accurate world model over time. Especially hard is the problem of perceptually segmenting objects and then tracking those objects. We suggest a representation language for plans that is based on perceptual data, not objects. The second major p...

Since the genus Itersonilia was established as a fourth genus in the family Sporobolomycetaceae by DERx (1), three species have been described. The type species is I. perplexans Derx, which was first isolated from an infected leaf of Althea rosea (1). A second species, I. pyriformis Nyland was isolated from leaves of Acer macrophyllum (2). A third species, I. pastinacae Channon was reported (3)...

A microplot study under field conditions was carried out during 2 consecutive years to assess the effect of root-knot nematode infection (2,000 Meloidogyne incognita eggs/kg soil) on three winter ornamental plants: hollyhock (Althea rosea), petunia (Petunia hybrida), and poppy (Papaver rhoeas). Effects of root-dip treatment with the biocontrol agents Pochonia chlamydosporia, Bacillus subtilis, ...

Introduction The narrow-leaved cattail wetland (Hopfensperger and Engelhardt 2007) known as Dyke Marsh formally became a land holding of George Washington Memorial Parkway (GWMP, a unit of the national park system) in 1959, along with a congressional directive to honor a newly-let 30-year commercial sand and gravel dredge-mining lease at the site (Litwin et al. 2013; Figure 1). Dredging continu...

AIMS AND OBJECTIVES The aims of the present study were to determine and compare the effects of different concentrations of Althaea officinalis extract, 0.2% chlorhexidine (CHX), and penicillin on Streptococcus mutans and Lactobacillus acidophilus in vitro. MATERIALS AND METHODS The laboratory study was done, for a period of 8 weeks. Minimum inhibitory concentration (MIC) in the test tube, min...

BACKGROUND/AIM [corrected] Cronobacter sakazakii (C sakazakii) is an emerging food-borne pathogen that has increasingly raised interest among the whole public community and food industry, especially in the production of powder infant formula. It has been isolated from water, sediment and soil. The question is whether this pathogen can be present in herbal teas. Herbal teas are widely used for g...
