Interlanguage development, mainly as far as written production is concerned, may be facilitated in learners who are trained to elaborate an input, which is recognized as 'meaningful'', through noticing and attention management tasks, and through tasks focusing on production, which have an influence on the re-organization of forms and meaning. Therefore, the action-research aimed at verifying how written performance in ab initio students reflec...

Stereolithography (SL) is a method which produces any object of complex geometry with desired qualities from its computer aided design and the production is realized by the free-radical photopolymerization reaction. The photopolymerization as the fundamental process of SL production is not yet well understood. The main purpose of this study is to develop mathematical models to contribute to the understanding of the reaction kinetics of the pho...

UNAIDS reported difference in HIV infection across the sexes (UNAIDS, 1998). We therefore speculated that these differences could be reflected in utilization of VCT services which is regarded as an important strategy in the management of HIV/AIDS pandemic. Therefore we set out to assess the attitudes of VCT clients at the end of service delivery as some attitudes may deter potential users from visiting the facilities for the service.

Ageratum conyzoides is a member of the family of "Asteraceace" and it is increasingly being used in traditional medicine for the treatment of diverse ailments. The book contains an indepth review of literature on medicinal plants. It also reported studies on the purification, isolation and characterization of active phytochemicals from Ageratum conyzoides. Antioxidant, anti-cancer, anti- influenza, anti-HBeAg and anti-HBsAg properties as well ...

Despite, being the global leader in milk production, productivity and per capita availability is abysmally low in India. As technological interventions are the key player to boost production, an appropriate and feasible pricing model is indispensable to augment the productivity. The relative prices have been drastically affected due to the ignorance of factor allocation, yield levels, technology and government policies. Since dairying is being...

HIV, the ever-growing disease, is still to become an epidemic all over the world. There aren''t many causes for HIV but those which persist are all related to human flaws. Nevertheless since HIV persists in our society, we, the most intelligent people on planet must fight to treat and eliminate the dreadful disease. The book contains a small step towards the same. Here, the aim is to rationally design a molecule which substitutes pyrimidine mo...

This book deals with the development, application and validation of techniques for data analysis in view of supervisory control of cyclic systems, including and integrating aspects of monitoring, diagnosis and control. Two so far largely separated tools for data mining of process data are used as a basis for the presented developments. These are Principal Component Analysis (PCA) and Qualitative Representation of Trends (QRT). A pilot-scale se...

In South Africa, the levels of unemployment and poverty are extremely high and these are two of South Africa''s most pressing problems. Over the past 28 years several major programmes have been initiated in South Africa to counter unemployment and poverty. This did not solve the unemployment problem. Since 1994 the African National Congress (ANC) government has implemented large-scale programmes with similar objectives to those before 1994. Af...

Nutrient levels in soils of natural semi-arid ecosystems are controlled within tight cycles which find a natural balance between uptakes by plants and the atmosphere and inputs from decomposition and other processes. Where cultivation is introduced, dramatic changes occur in components of these cycles. The book shows the impact of land use change on the levels of soil organic carbon, total soil nitrogen and available phosphorus in a semi-arid ...

The Kalman filter is a set of mathematical equations that provides an efficient computational means to estimate the state of a process, in a way that minimizes the mean of the squared error. The filter is very powerful in several aspects: it supports estimations of past, present, and even future states, and it can do so even when the precise nature of the modelled system is unknown. It has several applications such as Noise Cancellation, Track...

In recent years, research and development in the field of "natural interface" technologies and machine learning techniques have gained paramount importance. Text to Speech (TTS) conversion and Automated Speech Recognition (ASR) form a key part of such interface technologies. On the other hand, the future generation of intelligent computing devices will obviously require applications like machine learning based classifiers to perform classifica...

Fathers of gay sons were the focus of this study, the purpose of which was to examine the father''s perceptions of their relationship with their son concerning the disclosure of their homosexual identity (preference). The study examined fathers'' perceived emotive, cognitive, and behavioural reactions during disclosure and the way these related to their prior father-son relationship. Fathers shared and interpreted their disclosure experiences ...

Corporate Orchestras examines the intersection of corporate and individual identity in the modern workplace - particularly focusing on the tension between identities as individuals are welcomed into existing workplaces and the various induction and socialisation processes used to set the limits of expression for those identities. This works ask whether the collective endeavour of the modern workplace is in effect a concerto in We-major or We-m...

In the last few years, the use of numerical methods as Monte Carlo, stochastic models and strongly correlated systems close to phase transitions, has increased exponentially with unexpected success also in fields really faraway from physics as for example biology, chemistry, finance, sociology and climatology. In this book we expose a new Monte Carlo variational approach applied to t-J and t-t''-J Models for describing the experimental phase d...

The tax system is of central importance in democracies like Brazil and United Kingdom, and certain values linked to equity, fairness, and the rule of law must be respected in distinguishing between tax avoidance and tax evasion. The faint border between the legal and illegal will be analyzed under the legislation, jurisprudence and doctrine of Brazil and United Kingdom. Also, will be examined the mechanisms utilized by Brazil and United Kingdo...

In this book, a time continuous version of the discrete time Couzin-Vicsek algorithm (CVA), which describes the iterations of individual among animals societies such as schools of fish and flocks of birds, is used to simulate the velocities and positions of self-driven particles (SDPs). This algorithm is based on the discrete CVA, which assumes that at each time step, the velocities and positions of the SDPs are updated, and the velocity direc...
