Since the publication of this book, in 1983, several new and exciting
developments have taken place in the field of Plant Tissue Culture, and
it now forms a major component of what is popularly called Plant Biotechnology.
Many of the important crop plants which were then regarded
as recalcitrant are now amenable to regeneration from cultured protoplasts,
cells, and calli, enabling subjection of these crops to improvement
by biotechnological methods of cell manipulation.
Third, information is better if it is more highly disaggregated (more detailed). For
example, data on wastes produced by individual processes or product lines is better than data on
wastes created by an entire factory. For instance, accounting that assigns a wide variety of costs
to overhead is problematic because of a lack of disaggregation. Disaggregation is necessary to
incremental financial analysis -- i.e., the evaluation of investment or production opportunities
based on their incremental costs and incremental contributions to revenue.
In conclusion, the results reported herewith show a significant relationship between
epifluorescence microscopy and flow cytometry, but coefficients of variation were
considerably lower for bacterial counts estimated by flow cytometry than epifluorescence
microscopy. Generally, the use of flow cytometry in marine microbiology reduces the
processing time of the sample and increases the number of processed samples.
Prior to the 1930s, there was little federal
role in providing disaster assistance to
farmers and ranchers. In 1886, Congress
appropriated $10,000 for the Department
of Agriculture to purchase seed for
drought-stricken farmers in Texas, but
President Grover Cleveland vetoed the act
with the message, “Federal aid in such
cases encourages the expectation of
paternal care on the part of government
and weakens the sturdiness of our
national character” (Porter, 1988).
Both infrared and Raman spectroscopy are extremely powerful analytical
techniques for both qualitative and quantitative analysis. However, neither
technique should be used in isolation, since other analytical methods may
yield important complementary and/or confirmatory information regarding the
sample. Even simple chemical tests and elemental analysis should not be
overlooked and techniques such as chromatography, thermal analysis, nuclear
magnetic resonance, atomic absorption spectroscopy, mass spectroscopy, ultraviolet
and visible spectroscopy, etc.
Once you’ve determined that an investment home fits your financial goals, it’s time to decide
whether or not you’re willing to deal with the responsibilities of being a landlord. There may
be 3 a.m. phone calls to answer, late rents to collect, unsatisfactory tenants to evict, repairs and
maintenance to attend to, paperwork to be updated, income and/or deductions to be claimed,
taxes to be paid, and various new laws to obey. It’s a major commitment, but keep in mind that
you can always hire professionals to take care of many day-to-day responsibilities.
The East African organic products standard can be used for self-assessment by producers,
declarations of conformity in the marketplace, certification by certification bodies in the region, or
other kinds of verification. If the standard is used for the purposes of third-party certification,
inspection and certification should be carried out in accordance to international norms, such as ISO
Guide 65 or the IFOAM Accreditation Criteria.
The most extensive and detailed account of the domain that concerns me
here was put forward by Dewey in Art as Experience. Dewey argues that the
aesthetic aspects of art and those of everyday life lie on a continuum. However, as
we will see, Dewey offers a set of criteria for aesthetic experience that exclude most
or all of the examples introduced above.
There will be cases where chemical interferences can be identified for a
particular method but the chances of encountering them in real life may be improbable. The
analyst has to decide at what point it is reasonable to stop looking for interferences. These
parameters apply to both qualitative and quantitative analysis. The selectivity of a method is
usually investigated by studying its ability to measure the analyte of interest in test portions
to which specific interferences have been deliberately introduced (those thought likely to be
present in samples).
Ensuring the emergency services and the public know where and when it will flood, and how serious the
flooding is likely to be, is a complex task. The Environment Agency has increased the number of households and
businesses offered a flood warning service. We have also launched a new National Flood Forecasting Centre with
the Met Office that will allow us to better predict the scale and timing of flooding events and monitor them as they
Despite the fact that some distressed investors have abandoned the market in the last few
years as the supply of new defaulted debt has diminished, there still exists an impressive number
of investors who specialize in this rather unique asset class. The primary vehicle for investing is
a limited partnership, whereby a particular distressed-asset investment manager raises funds from
financial institutions and wealthy individuals.
This effect was
less than originally feared, however—in part be-
cause earlier expenditures for improving health
and education had enduring effects. As a result of
this experience, most countries’ adjustment pro-
grams today try to rationalize overall government
spending while maintaining cost-effective expen-
ditures in health and education. Despite these im-
provements, much is still to be learned about more
efficient ways of carrying out stabilization and ad-
justment programs while protecting the poor.
Policies to expand schooling are also crucial for
Lecture Basic statistics for business and economics - Chapter 1: What is statistics?. When you have completed this chapter, you will be able to: List ways that statistics is used, know the differences between descriptive and inferential statistics, understand the differences between a sample and a population, explain the difference between qualitative and quantitative variables, compare the discrete and continuous variables, recognize the levels of measurement in data.
The book is divided into four main parts: key issues in researching language learning/teaching, data collection, data analysis and writing up research. Both qualitative and quantitative methodologies are discussed, alongside popular mixed-methods approaches, such as triangulated studies, thus covering many of the methods commonly employed in the field.
Significantly lower salivary OC concentrations in both healthy and diseased smokers than
their non-smoker counterparts were reported by Özçaka et al. (2011b). The detrimental
effects of smoking may explain these decreases in salivary levels of OC in smokers also
indicating a deficiency in tissue response to the injuries in smoker subjects. The differences
in patient numbers and/or the possible differences in the disease activity states may explain
the differences in findings of the present study and the previous ones.
With the advent of the atomic force microscope (AFM) came an extremely valuable
analytical resource and technique, useful for the qualitative and quantitative surface
analysis with sub-nanometer resolution. In addition, samples studied with an AFM do
not require any special pretreatments that may alter or damage the sample, and permit
a three dimensional investigation of the surface.
Plant tissue culture
Most methods of plant transformation applied to GM crops require that a whole plant is regenerated from isolated plant cells or tissue which have been genetically transformed. This regeneration is conducted in vitro so that the environment and growth medium can be manipulated to ensure a high frequency of regeneration. In addition to a high frequency of regeneration, the regenerable cells must be accessible to gene transfer by whatever technique is chosen (gene transfer methods are described in Chapter 3).
Carmago et al. (1992) found that the rivers nearer industrial discharge point have adverse
impact to the environment as well as to macrobenthic communities. Toxic contaminants
from surface runoff, sewage discharges and industrial discharge have caused negative
impacts towards the freshwater macrobenthic communities. The presence of substance
chemical such as ammonia, chlorine, cyanide, metals, PCBs, pesticides and phenols would
caused a decline pattern on the number of species and changes in the species composition.
