A series of laboratory and greenhouse experiments evaluated the entomopathogenic nematodes Steinernema scarabaei Stock & Koppenhöfer, Heterorhabditis bacteriophora Poinar, and H. zealandica Poinar for control of secondand thirdinstar cranberry white grub, Phyllophaga georgiana Horn (Coleoptera: Scarabaeidae), in cranberries. Steinernema scarabaei was the most effective species with 76 100% cont...

Studies were performed in the laboratory, greenhouse and field to assess the potential of Agrotis ipsilon multicapsid nucleopolyhedrovirus (AgipMNPV) and a viral enhancing agent, M2R, for suppression of Agrotis ipsilon (Hufnagel). In laboratory droplet feeding bioassays, AgipMNPV was shown to be highly active against third-instar A. ipsilon. The optical brightener M2R significantly reduced LD50...

Control effect is not ideal for traditional control method and wired control system, since greenhouse temperature has such characteristics as nonlinear and longtime lag. Therefore, Fuzzy-PID control method was introduced and radio frequency chip CC1110 was applied to design greenhouse wireless intelligent monitoring and control system. The design of the system, the component of nodes and the de...

An effects system can be used to delimit the scope of computational effects within a program. This information is not only useful for the programmer, but also can be used in the definition of a number of optimizations. Most effects systems have been defined for functional languages with simple state. Greenhouse and Boyland have recently suggested how an effects system could be used within Java....

We present results from a new critical review of the atmospheric Greenhouse (GH) concept. Three main problems are identified with the current GH theory. It is demonstrated that thermodynamic principles based on the Ideal Gas Law must be invoked to fully explain the Natural Greenhouse Effect, which essence is the boost of global surface temperature above that of an airless planet exposed to the ...

The Sun was fainter when the Earth was young, but the climate was generally at least as warm as today; this is known as the ‘faint young Sun paradox’. Rosing et al. [1] claim that the paradox can be resolved by making the early Earth’s clouds and surface less reflective. We show that, even with the strongest plausible assumptions, reducing cloud and surface albedos falls short by a factor of tw...

GROWTH AND V?ELFARE LOSSES FROM CARBON EMISSIONS RESTRICTIONS: A GENERAL EQUILIBRIUM ANALYSIS FOR EGYPT* This paper is an assessment for a particular country, Egypt, of the economic effects, under various conditions, of carbon emission restrictions. Like other work, it is an exemplification of some of the economic possibilities. However, it extends the domain of possibilities and suggests some ...

Recent assessments agree that tropical cyclone intensity should increase as the climate warms. Less agreement exists on the detection of recent historical trends in tropical cyclone intensity. We interpret future and recent historical trends by using the theory of potential intensity, which predicts the maximum intensity achievable by a tropical cyclone in a given local environment. Although gr...
