  • 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.

  • 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.

  • 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).

  • 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 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 happen.

  • 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 promoting health.

  • 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.

  • SPB2 2/27/2003 4:06 PM Page 35 2 Plant tissue culture Introduction 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).

  • 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.

  • 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.
