  • Factors predisposing to colorectal cancer in UC patients consist of pancolitis, duration of disease, active disease and its severity. Early UC onset is another independent risk factor. Beside these factors, dysplasia represents the precancerous lesion from which colorectal cancer subsequently arise (Morson, 1962; Morson & Pang, 1967). In fact, 70% of patients with colorectal cancer on UC have dysplasia on colorectal mucosa (Taylor et al., 1992; Connell et al., 1994).

  • In Hungary, the law provides for a three-tiered territorial system of development councils: at the municipality group, county and county group level. The latter were created to handle the larger decentralised development issues. While the system seemed a logical approach to development at different levels, it has been criticised for inadequate local (particularly: private sector and civil society) representation, lack of coordination among tiers, limited decentralisation of financial resources and a lack of identification of actors with the county groups, which many consider arbitrary.

  • A body of research has determined that, by expanding the availability of low cost family planning services to a broader set of low-income women, the savings associated with averted unplanned pregnancies and other health improvements substantially exceed the cost of additional family planning services. 16 Research has demonstrated that publicly funded family planning services are effective in promoting contraceptive use among low-income women and in averting unplanned pregnancies.

  • The usual approach of epidemiological studies is to measure the association between at least one specific pollutant (e.g. PM, NOx, CO or O3) and health outcomes. These specific components are usually highly correlated with other pollutants and are considered indicative of the complex pollutant mixture. It is unclear how much the associations reported in epidemiological studies represent the independent effects of specific pollutants.

  • The endoplasmic reticulum (ER) and the Golgi apparatus both maintain their specific morphology, composition, and function in spite of the exchange of proteins and lipids between the two organelles through membrane trafficking. The morphology of the Golgi apparatus is closely linked to the balance between anterograde (ER-to-Golgi) and retrograde (Golgi-to-ER) transport. It has been reported that the inhibition of anterograde transport leads to the redistribution of Golgi components to the cytoplasm or the ER (Storrie et al., 1998; Ward et al., 2001; Miles et al., 2001).

  • Alberta is proving that environmental protection and economic development can happen at the same time. The province has shown leadership through legislation and policies involving land reclamation, water controls, air quality, and human and ecosystem health. In the oil sands, current production methods mean that more energy is needed to produce a barrel of oil than conventional oil. But the gap is closing. Technology continues to advance, reducing the energy and environmental impact of oil sands recovery. ...

  • Most agricultural commodities are processed in some way. Some fruits and vegetables are canned, dried or frozen. Meat animals are slaughtered, cut up, and chilled. Wheat is ground, and the flour is baked into bread. Soybeans are crushed, and the oil is made into margarine and shortening; the meal is used for livestock feed or refined for high-protein flour. Cotton is spun into thread and yarn; the yarn goes into cloth, and the cloth into shirts and dresses and sheets. Byproducts of many agricultural products yield glycerin, fatty acids, enzymes, hormones, and many...

  • From this early stage, the term ‘independent’ gained romantic connotation, signifying the brave efforts of rebels fighting against a powerful trust. Independent production in this era is often given the credit for a number of landmark developments, including the shift of the centre of gravity of the film business to California and the initiation of the star system, although both claims owe more to myth than reality.

  • Gamma-retroviral vectors, commonly designated retroviral vectors, were the first viral vector employed in Gene Therapy clinical trials in 1990 and are still one of the most used. More recently, the interest in lentiviral vectors, derived from complex retroviruses such as the human immunodeficiency virus (HIV), has been growing due to their ability to transduce non-dividing cells (Lewis et al. 1992; Naldini et al. 1996), an attribute that distinguishes them from other viral vectors, including their simple counterparts, gammaretroviral vectors.

  • While almost any type of security can be used in a repo, funds prefer to have U.S. Treasury or other government obligations as the collateral for most of their transactions. For added security, the collateral must equal at least 102 percent of the loan amount. 7 The transaction is called a repurchase agreement because the securities are actually sold to the lender or investor at the beginning of the period of the loan; the borrower agrees to repurchase the securities at the end of the loan term, usually at the same price.

  • Expanding nursing education programs at all levels is essential to ensuring access to quality health care for the world’s population. The easing of the nursing shortage in some nations is a direct result of the global financial crisis and should not be used as justification to cut funding for entry-level and advanced programs that prepare professional nurses.

  • The introduction of cloud computing is going to be gradual. Currently we are only in a phase of preparation with a few pioneers offering services that can be re- garded as belonging to cloud computing. Meanwhile, many large high-tech compa- nies are building huge data centres loaded with hundreds of thousands servers to be made available for customer needs in the near future. 7 Amazon has been the first mover in the field, providing access to half a million developers by way of Amazon Web Services (initially developed for internal pur- poses).

  • To the extent that mismatch is important, closing racial and ethnic gaps in employment and earnings requires improving the access of spatially-isolated minority workers to the full set of employment opportunities within regional economies. Improving accessibility can be accomplished through some combination of community development, residential mobility, and transportation programs. 2 Among the latter set of options, a potential tool for enhancing accessibility would be to increase auto access for racial and ethnic minorities.

  • Calculating and Expressing Valuation. It can be dif- ficult for a user to accurately value their ideal resource bundles. There needs to be a simple and effective way for people to express their resource need and calculate its value. To stress this point, imagine a market inter- face that asked the user for their valuation, one ques- tion at a time, over the entire space of good combina- tions. This painful approach would require the user to think about their valuation for a whole slew of bundles, a time-consuming and sometimes difficult task.

  • “Commute trips” include those traveling between home and work. There is a broad literature of studies concerning the valuation and treatment of time savings for commute trips, which is discussed in Forkenbrock and Weisbrod (2001) and Litman (2008). There is also a line of research (Madden, 1985 and Zax, 1991) which shows that businesses ultimately end up paying a premium to attract and maintain workers in parts of urban areas where transportation costs to employees are higher.

  • Zambia’s economic growth slowed to 6.6% in 2011 from 7.6% in 2010, mainly as a result of a weaker mining sector performance. However, the medium-term economic outlook appears favourable, underpinned by sustained expansion in agriculture, construction, manufacturing, transport and communications, and by a rebound in mining. Inflation is projected to remain in single digits, reflecting prudent monetary policy, while the objective of exchange rate policy is to maintain external competitiveness.

  • The ability of camels to go for varying periods of time without water is a major factor in placing the family camp and camel herd in relation to sources of water. This ability is affected by several factors such as how much work (including walking in search of its feed) the camel has to do and the ambient temperature. Camels spend more energy (involving the use of water for evaporative cooling) at high temperatures, increasing thus the need for water and reducing the time between waterings. The management implications of this are that camels should be provided with shade,...

  • Last year, applications to nursing degree programs increased by 73.7% in the United Kingdom (UK), making nursing the top subject area in terms of the highest number of applications received. Despite the strong student interest, the Department of Health in England recently announced the need to cut funding to nursing programs by up to 15% over the next 3 years. Universities in England have confirmed that the number of commissions is likely to decrease by approximately 10-15%, which would curtail future growth in nursing programs. ...
