Taschenbuch. Condizione: Neu. Neuware -Well-planned and managed cities (urbanization) are the powerhouses of economic growth and employment. Urbanization and growth are symbiotically linked: no country has ever reached middle income status without a significant urban transition. Thus, cities (urbanization) shape the direction of economic incentives, activities and business opportunities. They offer economies of scale, agglomeration, act as transport hubs, and provide markets for goods and services. More fundamentally, cities generate growth and employment opportunities through infrastructure development and by attracting domestic and foreign investments in various sub-sectors such as housing, construction, ICT and the digital economy. Given that Sub-Saharan Africa is the second fastest urbanizing region after Latin America and the Caribbean, the region should make urbanization count by making strategic investments in its urban population and infrastructure development to unlock the economic potential for growth and employment creation. The cost of inaction on urbanization has the potential to dim future development prospects in the region. The time to act and invest in urbanization is now!VDM Verlag, Dudweiler Landstraße 99, 66123 Saarbrücken 52 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Human resource policies are the formal rules and guidelines that businesses put in place to hire, train, assess, and reward the members of their workforce. These policies, when organized and disseminated in an easily used form¿such as an employee manual or large postings¿can go far toward eliminating any misunderstandings between employees and employers about their rights and obligations in the business environment. 'Sound human resource policy is a necessity in the growth of any business or company,' wrote Ardella Ramey and Carl R.J. Sniffen in A Company Policy and Personnel Workbook. 'Recognition of this necessity may occur when management realizes that an increasing amount of time is being devoted to human resource issues: time that could be devoted to production, marketing, and planning for growth. Effective, consistent, and fair human resource decisions are often made more time consuming by a lack of written, standardized policies and procedures. The purpose of this book will pave the way for solving the issues arising between employers and employees in Airlines industry.I wish the readers all the best for a great Journey to be cherished.VDM Verlag, Dudweiler Landstraße 99, 66123 Saarbrücken 76 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The list of countries permitting or requiring IFRS is expanding over the years and does also include nations of the Islamic financial system. However, since the Islamic world has its own rules and regulations referring to the financial sector, not every Western accounting standard is equally suitable for financial statements of countries being part of the Middle Eastern faith. The purpose of this book is to examine whether IFRS 9 - or to be more specific, its second phase impairment - is suitable for certain Islamic financial instruments or not. In order to answer this question, differences in Murabaha, Mudaraba and Ijarah contracts of two major banks situated in Bahrain, that might be appeared because of the implementation of IFRS 9, were analysed in detail. The analysis showed that, apart from initial concerns and possible complications that might have arisen, Islamic banks and corporations, or at least those that operate under the same conditions and rules as the banks surveyed, have no objections to adopting IFRS 9. Nonetheless, if an IFRS implementation is to run smoothly, it must be well planned and prepared and should not be underestimated.VDM Verlag, Dudweiler Landstraße 99, 66123 Saarbrücken 80 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Freshwater prawn aquaculture is not popular in West Africa, subject to low level of scientific and technical know-how on the subjects of its ecology, biology, genetics and its production techniques. However, in order to bridge the gap in the scientific knowledge needed for sustainable development of it commercial farming, this book project was initiated. The authors researched and summarized the stock characteristics of two wild populations of M. vollenhovenii (Herklots, 1857) around two geographically distant and unconnected rivers in West Africa and discovered that M. vollenhovenii though ecologically diverse, are not morphologically and genetically different within the two stocks. Other inferences drawn from their genetic diversity suggested good level of adaptation, long term survival, ability to resist disease, fast growth and high reproduction rates by these two wild populations. These results emphasized that specimens from the two stocks have high cultivability potentials. This book was however, written for the enhancement of the body of knowledge; to encourage translocation and domestication efforts, even commercial culture of M. vollenhovenii in West Africa.VDM Verlag, Dudweiler Landstraße 99, 66123 Saarbrücken 64 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Sixty-one groundwater samples were collected from the hard rock terrain of Nanganur region of South India, were evaluated for hydrogeochemistry as well as groundwater quality for drinking and irrigation purposes. Additionally, the probabilistic non-carcinogenic human health risks associated with fluoride and nitrate concentrations were assessed using the US Environmental Protection Agency (USEPA) mathematical model. The hydrogeochemical facies, i.e. Ca2+-Mg2+-SO42- and Na+-Cl--SO42-, identified are result of weathering and dissolution of rocks, ion exchange between Ca2+ and Na+, and precipitation of CaCO3, and also due to influences of anthropogenic sources. Molar ratio Na+/Cl-, and distributions of Ca2++Mg2+ versus HCO3-+SO42-, Ca2++Mg2+ versus TC, and Na++K+ versus TC indicate that silicate weathering is the prime source for the ions. Gibbs diagram also suggests that rock-water interaction is the primary process of ionic concentrations in this groundwater system. As per the classification based on US salinity diagram, 18% groundwater samples show medium salinity and low sodium hazards and 73% of, them have high salinity and low sodium hazards.VDM Verlag, Dudweiler Landstraße 99, 66123 Saarbrücken 72 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Thermoluminescence (TL) is extensively used for the study of defects in insulators and semiconducting materials. TL is observed when a part of the irradiation energy is used to transfer electrons to traps. Radiation with appropriate energetic photons causes photo-ionization of the luminescence centers brings the electrons to the conduction band (CB). Some of these electrons traps and occupy levels at depth energy levels below the CB. This energy stores in the form of the trapped electrons will comeout at eleviated temperatures and the materials releases the energy because of this is called TL. Study of the kinetic parameters of the TL peaks is significant for understanding of these mechanisms. Few dielectric materials show transient phenomenon on heating followed by irradiation. These phenomena display the same pattern on behaviour for TL, thermally stimulated conductivity (TSC) and exoelectron emission (TSE). These dielectric materials can be used for radiation dosimeter applications.VDM Verlag, Dudweiler Landstraße 99, 66123 Saarbrücken 76 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Using the example of a complicated problem such as the Cauchy problem for the Navier--Stokes equation, we show how the Poincare--Riemann--Hilbert boundary-value problem enables us to construct effective estimates of solutions for this case. The apparatus of the three-dimensional inverse problem of quantum scattering theory is developed for this. It is shown that the unitary scattering operator can be studied as a solution of the Poincare-Riemann--Hilbert boundary-value problem. The same scheme of reduction of Riemann integral equations for the zeta function to the Poincare--Riemann--Hilbert boundary-value problem allows us to construct effective estimates that describe the behaviour of the zeros of the zeta function very well.VDM Verlag, Dudweiler Landstraße 99, 66123 Saarbrücken 52 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Forensic Clinical Anatomy may be defined as the practical application of Clinical Anatomy to ascertain and evaluate medico-legal problems. Individual Anatomy (normal anatomy, anatomical variations, age-, disease- or surgery-related modifications) may acquire relevant significance in various fields of Legal Medicine, such as Child Abuse, Sudden Death, Medical Responsibility and/or Liability, Personal Injury and Damage. Anatomical data of forensic interest may arise from the correct application of methods of ascertainment and anatomical methodologies may then be required for further comprehensive analysis. The rigorous interpretation of the anatomical data, derived from the ascertainment phase and analysed on the basis of pertinent literature, may be pivotal for the correct application of evaluation criteria in various forensic contexts. Awareness of the relevance of Individual¿s Anatomy should be one of the principles guiding the Clinician to Personalized Medicine; conversely, in Personalized Justice, medico-legal analyses cannot ignore the implications of individual anatomy in terms of ascertainment and evaluation.VDM Verlag, Dudweiler Landstraße 99, 66123 Saarbrücken 88 pp. Englisch.
