  • In all of history, no children have had more money of their own, more pressure to spend it, and less guidance in how to do it than the kids of America at the dawn of the 21st century. “Today, more than ever, children must learn about money, for it is both a source of confusion and an indispensable tool they must learn to use.” Those words made a lot of sense back in 1950, in a Kiplinger’s magazine article entitled “Will Your Child Know the Value of a Dollar?” And they're even more true today....

  • For this book, the term desalination is used in the broadest sense of the removal of dissolved, suspended, visible and invisible impurities in seawater, brackish water and wastewater, to make them drinkable, or pure enough for industrial applications like in the processes for the production of steam, power, pharmaceuticals and microelectronics, or simply for discharge back into the environment.

  • Needles: Standard disposable 22-24 gauge 1-1½-inch needles are used for plain FNAC. The length and caliber of the needle should fit the size, depth, location and the consistency of the target. For small subcutaneous lesions, one-inch 23-gauge needle is ideal while for a deep-seated breast lesion, longer and larger needle is required. Finer needles are also recommended for children, and for vascular organs like thyroid. Syringes: Standard disposable plastic syringes of 10ml are used. Syringe should be of good quality and should produce good negative pressure.

  • However, economic downturns can have a detrimental effect on the creation of new, innovative businesses when access to financing dries up. The key role of finance in the development of small and medium-sized enterprises (SMEs) is illustrated by Finland (Figure 3) where the peak in financial constraints coincided closely with the deep recession of the early 1990s and a downturn in self- employed. Economic growth suffers doubly in the long term since innovative new firms exert competitive pressure on established firms pushing them to innovate.

  • Our results suggest that stronger competition implies significantly lower interest rate spreads for most loan market products, as we expected. This result implies that bank interest rates are lower and that the pass-through of market rates is stronger, the heavier competition is. We find evidence of the latter in our error correction model of bank interest rates. Furthermore, when loan market competition is stronger, we observe larger bank spreads (that is, lower bank interest rates) on current account and time deposits.

  • Furthermore, Fisher’s estimate and the estimate based on NYSE and Flow of Funds data are very close to that found by Jovanovic and Rousseau (2001). Jovanovic and Rousseau use data from all of the major and minor exchanges, such as the NYSE, the regional exchanges, and the over-the-counter market. They compute estimates of the market value of all domestic corporations comparable to estimates of the Flow of Funds after 1945. (See their appendix for details.

  • Competition in the banking sector has been analysed by, amongst other methods, measuring market power (i.e. a reduction in competitive pressure) and efficiency. A well-known approach to measuring market power is suggested by Bresnahan (1982) and Lau (1982), recently used by Bikker (2003) and Uchida and Tsutsui (2005). They analyse bank behaviour on an aggregate level and estimate the average conjectural variation of banks.

  • This paper examines financial market comovements across European transition economies and compares their experience to that of other regions. Correlations in monthly indices of exchange market pressures can partly be explained by direct trade linkages, but not by measures of other fundamentals. A look at higher-frequency data during three crisis periods reveals the presence of structural breaks in the relationship between exchange-, but not stock markets.

  • SURVIVAL ON LAND POSES SOME SERIOUS CHALLENGES to terrestrial plants, foremost of which is the need to acquire and retain water. In response to these environmental pressures, plants evolved roots and leaves. Roots anchor the plant and absorb water and nutrients; leaves absorb light and exchange gases. As plants increased in size, the roots and leaves became increasingly separated from each other in space. Thus, systems evolved for long-distance transport that allowed the shoot and the root to efficiently exchange products of absorption and assimilation.

  • Containing Network Overload Network designers like think that their traffic models ideally stable, andthat their forecasts to are of future traffic will never be wrong.In real life, however, such assumptions are unwise, because any one of a number of problems may arise, resulting in network overload, and so congestion. The forecast may underestimate demand; there may be a short period of extraordinarily high pressure (for example at New Year, Christmas, or any public holiday, or following a natural disaster); or there may be a network link switch (exchange) failure. ...

  • Economists use the term equilibrium in the same way as the word is used in physics, to represent a steady state in which opposing forces are balanced, so that the current state of the system tends to persist. In the context of supply and demand, equilibrium refers to a condition where the pressure for higher prices is exactly balanced by a pressure for lower prices, and thus that the current state of exchange between buyers and sellers can be expected to persist. When the price is such that the quantity supplied of a good or service exceeds the...

  • This book is a quick-reference guide for tuning Oracle SQL. This is not a comprehensive Oracle tuning book. The purpose of this book is to give you some light reading material on my "real world" tuning experiences and those of my company, Mark Gurry & Associates. We tune many large Oracle sites. Many of those sites, such as banks, large financial institutions, stock exchanges, and electricity markets, are incredibly sensitive to poor performance. With more and more emphasis being placed on 24/7 operation, the pressure to make SQL perform in production becomes even more critical.

  • The vascular system serves two basic functions: distribution and exchange. Distribution includes transporting blood to and away from organs. The anatomical arrangement of the vasculature and physiologic control mechanisms that dilate or constrict blood vessels determine this transport. Changes in vessel diameters regulate blood pressure and determine the amount of blood flow to specific organs and regions within organs.

  • When unfired units are designed with higher steam conditions for combined cycle, multiple-pressure units are usually applied to increase exhaust heat recovery and enhance system performanc The intermediate level may be that required for steam injection fo NOx control and/or a process level. In applications using natural gas, a third pressure level will further enhance overall system performance. Typical design practice is that unfired HRSGs are convective heat exchangers that respond to the exhaust conditions of the gas turbine.

  • The listing of stock exchanges, perhaps even more than their demutualisation, has transformed their business model. Although demutualisation is claimed to have changed the ownership of stock exchanges, significant ownership stakes were often retained by previous member firms (Steil, 2002). Therefore, the fundamental governance structure of exchanges was not significantly impacted. Self-listing and the subsequent dispersion of ownership of exchanges have finally divorced their interests from those of broker dealers.
