While biotrophic fungal pathogens have generally been considered to have negative effects on phytophagous insects sharing the same host plant, very little is known about whether fungal infection may affect the dynamics of natural insect populations. This study was designed to determine the effects of fungal infection by Podosphaera plantaginis, a powdery mildew, of a shared host plant, Plantago...

Introduction: According to Rubenstein, “Falls are a common and often devastating problem among older people, causing a tremendous amount of morbidity, mortality and use of health care services including premature nursing home admissions (1, p. 37).” Thus, falls are a complex, multi-faceted issue consisting of medical, social, and economic components. Medically, the combination of a high inciden...

Maternal effects can have significant and long-term consequences on offspring behavior and survival, while consistent individual differences (i.e., personality) can have profound impacts on individual fitness. Thus, both can influence population dynamics. However, the underlying mechanisms that determine variation in personality traits are poorly understood. Maternal effects are one potential m...

Survival of the glassy-winged sharpshooter, Homalodisca vitripennis (Germar) (Hemiptera: Cicadellidae), was studied under various constant temperatures and feeding conditions. When provided a host plant (Citrus limon L. Burm. f.) to feed on during a 21-d trial, 100% mortality occurred at 0.1, 3.2, and 40.1 degrees C, whereas an average of 74-76% of adults survived in the 13.2-24.5 degrees C ran...

AANA Journal  December 2012  Vol. 80, No. 6 453 Anesthesia support personnel provide direct support to anesthesia providers. They bring extra supplies or equipment, prepare equipment for the case, maintain and clean equipment, and generally function as directed by the anesthesia provider. Given the importance of anesthesia support personnel in maintaining equipment essential to safe anesthesi...

We investigated how host plant phenology and plant species affected longevity, reproduction, and feeding behavior of an invasive weevil. Phyllobius oblongus L. (Coleoptera: Curculionidae) is common in northern hardwood forests of the Great Lakes Region. Adults emerge in spring, feed on foliage of woody understory plants, and oviposit in the soil. Preliminary data indicate that adults often fee...

Breast Feeding and Weaning Practices have a major effect on short term and long term nutritional status of infants. An attempt was made to find out the pattern of infant feeding practices in Thar Desert of Rajasthan so as to know the community perceptions existing in this area. Data were collected from 434 young women belonging to rural house-holds of Thar Desert. Analysis revealed that exclusi...

We present a fluid dynamics model for the drawing of hollow multilayer polymer optical fiber. A newtonian model is considered assuming slender geometries. Hollow core collapse during drawing and layer thickness non-uniformity are investigated as a function of draw temperature, draw ratio, feeding speed, core pressurization and mismatch of material properties in a multilayer.
