Experimental

This strategic lab guide explores the current methodological variety of molecular biology and genomics in a simple manner, addressing the assets and drawbacks as well as critical points. It also provides short and precise summaries of routine procedures as well as listings of the advantages and disadvantages of alternative methods.This lab book illustrates ways out of experimental dead ends and teaches a feeling for doing the right experiment at the right time.

THE USE OF INTENAL AUDIT FINDINGS IN GOVERNMENTAL ORGANIZATION : AN EXPERIMENTAL STUDY In modeling the effects of parental preferences on equilibrium outcomes under Tiebout choice, it is important to account for two key issues that do not arise under choice programs like vouchers. The first is that residential choice rations access to highlydemanded schools by willingness-to-pay for local housing.4 As a result, both schools and districts in high-choice markets (those with many competing school districts) are more stratified than in low-choice markets....

Data of unknown quality are useless! All laboratory measurements contain experimental error. It is necessary to determine the magnitude of the accuracy and reliability in your measurements. Then you can make a judgment about their usefulness. Replicates - two or more determinations on the same sample Example 3-1: One student measures Fe (III) concentrations six times. The results are listed below: 19.4, 19.5, 19. 6, 19.8, 20.1, 20.3 ppm (parts per million) 6 replicates = 6 measurements The "middle" or "central" value for a group of results: Mean: average or arithmetic mean ...

We present B EETLE II, a tutorial dialogue system designed to accept unrestricted language input and support experimentation with different tutorial planning and dialogue strategies. Our first system evaluation used two different tutorial policies and demonstrated that the system can be successfully used to study the impact of different approaches to tutoring. In the future, the system can also be used to experiment with a variety of natural language interpretation and generation techniques.

One of the more promising processes for the energetic transformation of waste is the anaerobic digestion of the Organic Fraction of Municipal Solid Waste. An experimental campaign was carried out on three different samples of OFMSW from Waste Separation, one as received and two obtained after mechanical treatment: OFMSW slurry (liquid fraction) and OFMSW Waste. Anaerobic Biogasification Potential and anaerobic digestion tests were carried out, investigating the effects of inoculum and pH. The OFMSW Waste was also examined to evaluate the possibility to dispose of it in a landfill.

This paper raises concerns that natural language front ends for computer systems can limit a researcher's scope of thinking, yield inappropriately complex systems, and exaggerate public fear of computers. Alternative modes of computer use are suggested and the role of psychologically oriented controlled experimentation is emphasized. Research methods and recent experimental results are briefly reviewed.

Experimental results showed that biochar application changed soil quality, resulted in improving the growth of Brassica juncea. We will report the difference of nitrogen and phosphorus balances (crop uptake, leaching, retention, etc.) in experimental pots. Our results indicated that the use of biochar from agricultural by-products would be beneficial for farmers, the environment under soil and climatic conditions in Thua Thien Hue province.

The purpose of this study was to evaluate the anti-inflammatory and the bronchodilator effects of Dinh Suyen P/H extract in experimental animals. The anti-inflammatory activity of Dinh Suyen P/H extract was evaluated in an induced peritoneal inflammation model in rats and amiant-induced granuloma model in mice.

In many solid-state laser pumped by flash lamps, thermal source distributed in laser rod is heterogeneous, complicated and cannot be described by explicit functions. Pumping process can be considered an adiabatic process. Thermal gradient generated within the laser rod is the result of the inhomogeneous distribution of absorbed energy. Calculation model and numerical method can help to determine the relation between the experimental values and thermal energy generated in laser rod.

In this paper, we present the experimental results in verifying the research hypothesis represented in the article “An epistemological analysis of the concept of quotient group” (Nguyen Ai Quoc, 2018) about the existence of three difficulties to students in first approaching the concept of quotient group. And these difficulties are derived from three epistemological obstacles: intrinsic, abstraction, and structuralisation.

In this research, experiments will be carried out to determine the pore structure, the pore size distribution of γ-Al2O3 particles. Modern and appropriate experimental methods are applied. Descriptions of the experimental methods and equipment are given. The first experiment is the pore structure determination of the material by using environmental scanning electron microscopy (ESEM). The second one is the pore size distribution determination with the help of Hg-porosimetry method. Experimental results will be presented and discussed.
