NASA's nanotechnology attempt started in 1996 and it resulted in the founding of the
Centre for Nanotechnology. Apart from this centre, the research has been focused on
the experimental research and development in computational nanoelectronics and
This chapter presents the uses of experimentation and the various types of experimental designs. It also discusses the advantages and disadvantages of the experimental method. After studying this chapter you will be able to understand: Uses for experimentation, advantages and disadvantages of the experimental method, seven steps of a well-planned experiment, internal and external validity with experimental research designs, three types of experimental designs and the variations of each.
In little more than a decade since the publication of the first edition of Science for Agriculture the
book has become a classic in its field. The book celebrated over a century of contributions by the
United States Department of Agriculture—State Agricultural Experimentation research system to
the growth of production and productivity of American agriculture.
This second edition is much more than an updating of their earlier work.
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....
The experimental research of the authors from 2003-2006 on the following agricultural products: Watermelon, sugarcane, cassava, groundnuts, maize and rice. The results show that post-harvest losses of agricultural products is very high: Watermelon 6.6 - 12.6%, sugarcane 1:46 to 3:26%, Wu 8.88 - 1.18%, rice 8:36 to 12:25%, 17:02% 13:33 Lac, San slices of 13:27 to 17:49% cassava flour and 5:17 to 8:22%.
To determine post-harvest losses mainly due to the fact cracked rice, the data were collected systematically based on real farmers and also by experimentations in two seasons (wet 2006, dry 2007). 2007 wet season experiments are being pursued today. The main factors considered in this study during data collection are:
• Harvest time before and after the seeds mature
• Harvesting methods manual, harvesters, combine harvesters
• drying method and cost-sun drying and mechanical drying
The idea for this book originated during a conversation in December
2006 with C. Deborah Laughton, Publisher, Methodology and Statistics, at
The Guilford Press, about the challenges of teaching research seminars or
other courses in which students conduct a thesis project. These students
could be senior undergraduates in advanced programs, such as honors
or specialization, or first-year graduate students.
This book is primarily aimed at undergraduate students undertaking scientific research projects as part of a
programme in medicine, nursing and midwifery, subjects allied to health and biological sciences, although
it is generally applicable to all project work. It will also be useful to professionals undergoing continuing
professional development (CPD) or changing to study at MSc masters level and who need revision on
scientific research methods.
The objective of the present study was to assess anti-obesity and body weight reducing effect of Docynia indica (W.) Decne fruit extract fractions base on experimentally obese mice model. Male mice (Mus musculus, Swiss strain of 4 weeks of age, weighed at 14-15g) purchased from National Institute of Hygiene and Epidemiology (NIHE) were housed in a
EXPERIMENTAL EVALUATIONS OF PUBLIC POLICY In so far as student test scores depend on school effectiveness, effectiveness sorting
is observable as an increase in the slope of school average scores with respect to student
The aim of this study was to assess the effects of Pomelo (Citrus grandis (L.) Osbeck) peel extracts (CGE) on activity of lipid-carbohydrate metabolic enzymes such as Carnitine pamitoyl-transferase (CPT), lipase, hexokinase, glucose 6-phosphatase and blood lipid glucose parameters in experimental obese and diabetic mice. The results showed that, in the experimental obese mice treated daily, orally with CGE at dose of 1200 mg/body weight for three weeks,
The objective of the present study was to develop an experimentally obese mice model and to investigate antiobesity and body weight reducing effect of Fortunella japonica peel extract fractions. Male mice (Mus musculus, Swiss race weighed at 14-15g) purchased from National Institute of Hygiene and Epidemiology (NIHE) were divided into 5 groups in which, the first group was fed with normal pellet diet (NPD) (Standard chow from NIHE), and other groups (2-5 groups) were fed high fat diet (HFD) containing 58% calories as fat for a period of 15 days. ...
The goals of experimental neuroscience research are fundamentally to gain mechanistic
understanding of the pathology of disease in order to identify appropriate
targets for potential pharmacological intervention and evaluation of putative therapies.
With the advances in gene manipulation and transgene technologies, we have
unprecedented ability to generate animal models of disease that more closely mimic
the clinical conditions.
Noninvasive techniques capable of investigating altered pathophysiologies are
now of paramount importance.
This paper specifies that research, analysis and estimate on marine environmental and biological conditions are very important for fishing ground forecast in offshore waters. The multi-variate regression equations among Catch Per Unit Efforts (CPUE), temperature structures and primary production have been established and used for monthly fishing ground forecast for purse-seine and drift-gillnet fisheries in the offshore waters of central Vietnam. The experiment forecast result in May, June and
After the domination of behaviourism in Anglo-American psychology during the
middle of the century, the impression has been left, reflected in the many texts on
research design, that the experimental method is the central tool of psychological
research. In fact, a glance through journals will illuminate a wide array of datagathering
instruments in use outside the experimental laboratory and beyond the
The transmembrane topology of presenilins is still the subject of debate
despite many experimental topology studies using antibodies or gene
fusions. The results from these studies are partly contradictory and conse-quently several topology models have been proposed. Studies of preseni-lin-interacting proteins have produced further contradiction, primarily
regarding the location of the C-terminus.
