[i] Nitrate (NO^~) leakage from forested watersheds due to disturbance is a well documented but not well understood process that can contribute to the degradation of receiving waters through eutrophication. Several studies have shown that large-scale defoliation and deforestation events in small forested watersheds in the eastern United States cause immediate and dramatic increases in NO^ flux ...

background:  the residual effect of triflumuron and pyriproxyfen on musca domestica l larval stages was studied in the laboratory. methods : both igrs at varying concentrations ranging between 0.5 to 2.5 mg/l were placed inside beakers with mice chow and vitamin b complex and water as food for the 1 st , 2 nd and 3 rd instars m.domestica larvae. results: both igrs inhibit m. domestica adult eme...

Objective(s): Human and animal studies have shown a close relationship between obesity and asthma severity. Here, we examined the effects of diet-induced obesity (DIO) on the expression levels of IL-1β, IRAK-1 and TRAF-6 mRNA in male Wistar rats tracheal after sensitization with ovalbumin (OVA). Materials and Methods:Twenty male Wistar rats divided to four groups, included, control group with ...

The removal of the top stem bud independently or in combination with the leaves, known as decapitation, can lead to changes in the physiological state of plants at the same age. The decapitation procedure reverses the symptoms of senescence which makes it an effective physiological approach to study the control mechanisms of delayed leaf senescence and rejuvenation. The process of rejuvenation ...

Fractional calculus; Conformable operators; Calculus on time scales Abstract A conformable time-scale fractional calculus of order a 2 0; 1 is introduced. The basic tools for fractional differentiation and fractional integration are then developed. The Hilger timescale calculus is obtained as a particular case, by choosing a 1⁄4 1. a 2015 The Authors.

Population changes of Heterodera glycines eggs on soybean in small field plots were influenced by the lepidopterous insect pest, Helicoverpa zea; however, few effects on eggs due to the presence of annual weeds were detected. Soybeans defoliated 15-35% by H. zea during August remained green and continued to produce new flowers and pods later into the season than soybeans without H. zea, resulti...

In May 2007, a widespread frost event defoliated much of Utah's high elevation aspen. About 5 weeks later, the frost-defoliated aspen produced a second leaf flush. The objective of this study was to characterize changes in leaf morphology and function in re-flush leaves following frost defoliation. Leaf size and thickness, photosynthesis, carbohydrate and nutrient status, and defense chemistry ...

This study's purpose was to examine whether functional overload with nandrolone decanoate (ND) administration increased muscle mass and steroid receptor concentration in aged rat soleus (Sol) and plantaris (Plan) muscle. ND (6 mg/kg body wt) was administered once a week for 4 wk, whereas control rats received sesame seed oil injections. Functional overload of the hindlimb Sol and Plan was induc...
