puparium and emerge. If present, like in mixed broods, N. vitripennis females emerge after males have emerged. The laboratory inbred strain N. vitripennis AsymC, whose genome has now been sequenced (Werren et al., 2010), was used for all the experiments. This wild-type strain was collected in The Netherlands and maintained in the lab since 1971 (van den Assem and Jachmann, 1999). Wasps were reared in mass culture vials (70 mm  20 mm) at 25 8C, constant light and around 45% relative…

and how engineers use statistical methodology as part of the engineering problem-solving process. This chapter also introduces the reader to some engineering applications of statistics, including building empirical models, designing engineering experiments, and monitoring manufacturing processes. These topics are discussed in more depth in subsequent chapters. Chapters 2, 3, 4, and 5 cover the basic concepts of probability, discrete and continuous random variables, probability…

adsorption plateau, at 7.3 (mol L-1 CR, and Q value of 4.73 ( 0.02 (mol g-1. Figures 3a and 3b show that as QCR values increased, the ζ-potential values became less negative and the mean particle diameter (D) increased, respectively. Desorption experiments indicated changes of less than 5% in the QCR values, evidencing high affinity between CR molecules and PS/PEG particles. Considering that the adsorption takes place at pH 7and that the pKb of CR is 4.6 ± 0.2 [30], the amount…

food anymore. This paper verified how the rat operates in its environment from the inserted stimulus in the experiment and its operant response can be observed and analyzed. It is possible to affirm that each organism has its own life history, acts in its environment and behaviors according to certain manners due to its conditioning, in the operant or respondent behavior levels. The experiment is a rich material that one can use to understand, in a clear way, how organisms operate and…

comparisons between different papers. There must be a better approach. 3.1 Throughput In our first experiment we increased the file size from 64MB to 1024MB in steps of 64MB. For each file size we ran the benchmark 10 times. The duration of the run was 20 minutes, but to ensure steady-state results we report only the last minute. Figure 1 shows the throughput and its relative standard deviation for this experiment. The sudden drop in performance between 384MB and 448MB is readily…

from the TDPMS measurement indicate that most of the organic gases will have high evolution intensity at temperatures below 200 oC. However, CO and N2 have almost the same evolution all over the range of temperatures between 100 and 1000oC. Model experiment was performed to investigate the impact of nickel and carbon on multicrystalline ingot quality. The diffusion length distribution was normal in the nickel contaminated ingot and comparable non-contaminated ingots while the carbon…

2007, in final form 10 April 2007 Published 16 May 2007 Online at stacks.iop.org/RoPP/70/883 Abstract Astronomers carry out observations to explore the diverse processes and objects which populate our Universe. High-energy physicists carry out experiments to approach the Fundamental Theory underlying space, time and matter. Dark Energy is a unique link between them, reflecting deep aspects of the Fundamental Theory, yet apparently accessible only through astronomical observation. Large…

fields of psychology and linguistics. One of the most recognized theories on learning called Behaviorism is based partly on the conditioned-reflex experiments by Ivan Pavlov, a Russian psychologist. Part of the theory in practice consists of providing a stimulus to cause a given response in a repetitive manner. American B.F. Skinner used these experiments to help create a therapy of behavior modification called conditioning. The audio-lingual language learning approach came about as a…

specialized vegetable seedlings has motivated farmers to adopt new farming techniques and technology of these techniques presented in this work. This work aimed to evaluate which of the four substrates used in the experiment had the best development of seedlings of arugula . The experiment was conducted at the Center for Higher Education biogeoquímica do Campos Gerais, Cescage in Ponta Grossa Pr laboratory The experimental design was a randomized complete block design with four…

Há vários experimentos que nos permitem ver a pressão atmosférica em ação. Um deles é o do ovo que entra e sai da garrafa. Assista aos vídeos abaixo para ver como isso acontece.
