Particularly it focuses on the opportunities and challenges of using the New media by journalists. Both qualitative and quantitative approaches were applied in the study underpinning the book. The result showed that almost all the journalists lack the knowledge to browse information from the Internet. Majority of them have no access to computer or Internet in their media organization. The journalists are far behind the information about events that are taking place worldwide as a result of lack of access to the Internet. Language barrier is also found to be another aspect that contributes to the low level use of new media by journalists. The problem of poor access to Internet is attributed mainly to the poor infrastructure of this media house. Lack of financial resource and less attention to new media sector is also another problem. Therefore, there is a strong need to direct priority to the expansion of new media infrastructure in the media organizations and building the capacity of journalists. ····· 1036199305

Discontinuous, discrete steel fibers of short lengths smaller in diameter have been used to improve the tensile and flexural strength of structural elements subjected to various loading conditions. Although the introduction of fibers into concrete reduces its workability, yet there is a significant improvement in the material behavior. The brittle characteristic of concrete is converted into a ductile one. Use of fibers alters the behavior of the fiber-matrix composite after it has cracked, thereby improving toughness. The goal of the work is to establish new relationships and to verify the available relationships between the various properties of Steel Fiber Reinforced Concrete (SFRC). Linear relationship between the flexural tensile strength and cube compressive strength are proposed for various percentages of fibers. The results indicate that fiber content in the range of 0.5% to 1% provide excellent toughness to normal strength concrete as compared to high strength concrete. ····· 1036199287

But the measured radiation data for a long period are not available all over Bangladesh. However, Bangladesh Meteorological Department has been recording different climatological parameters for years together throughout the country. Computation of solar radiation may be done using these meteorological parameters. For this purpose, we used theoretical formula proposed by different authors in literature. Monthly average data on sunshine duration (n), day length (N), relative humidity (R), temperature (T) etc. for a period of 28 years between 1980 and 2007 are used. So, this study is carried out to determine empirically global, diffuse and direct solar radiation on a horizontal surface for ten districts uniformly distributed all over Bangladesh (latitude 20o34 N - 26o34 N and longitude 88o01 E - 92o41 E) as well as to predict correlations for them. ····· 1036199283
für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Synthetic Aperture Radar(SAR)is an important tool for geosciences,remote sensing, surveillance,& reconnaissance now a day. In this work,a definition of UWB SAR image quality measurements is presented and the measurements for the UWB SAR images are performed. The most important SAR image quality assessments are spatial resolution, differential resolution, ISLR and PSLR. It is seen that elliptic areas are more suitable for delimitation of mainlobe and sidelobe areas of a UWB SAR image than rectangular areas for measurements of ISLR and PSLR. For this purpose a newly defined Impulse Response Function (IRF-SAR) is used instead of the widely used sinc function. In this book, the simulated CARABAS-II data is employed and the simulations are performed by Matlab. Global back projection (GBP), a time domain algorithm is used due to its time-domain characteristics such as extreme range migration handling and manageable motion compensation. But its main limitation is computational cost. This book uses a simple and causal writing style to presents the SAR image quality measurements pleasantly and nicely so that readers can enjoy it easily. ····· 1036199242

A biological treatment called vermicomposting technique was employed to expose four different ratios of sludge (20, 50, 80, and 100%) mixed with goat manure and rice straw as a composting material to the earthworm species Eisenia fetida for four weeks. For the chemical technique, the sludge was washed with a mixture of two reagents (Na2 EDTA and Na2S2O5) at different volumes of washing solution (2.5, 5, and 7.5 mL to 1 g of sludge). The best reduction of heavy metals occurred in 7.5 mL with a percentage reduction of 5%, 12%, 16%, and 24% per gram sludge for Al, Ni, Zn, and Pb, respectively. Based on the findings, the vermicomposting technique shows greater potential over the chemical washing technique in reducing heavy metal concentration in electronic sludge. ····· 1036198622

Molecular diagnostic methods using biomarkers are increasingly advancing due to their non-invasive nature and are greatly benefited by the implementation of microsystems, as minute amounts of sample can be analyzed in a quick, cost-effective and highly sensitive way. Still a challenging feature is multiplexity in analysis: diseases like tumor, cardiovascular, Alzheimer s, are related to not only one but several biomarkers which should all be addressed in a test in order to assess reliably the patient s condition. This work describes an acoustic wave microsystem integrating microfluidics to compartmentalize its surface into discrete domains and achieve multiplicity. The development steps are described from concept to design, fabrication, evaluation, and proof-of-principle through detection of four protein cardiac markers. The sensitivity and reproducibility of the sensing domains, as well as the highly selective capture of the desired biomarkers are very promising for the development of the system into an integrated lab-on-chip diagnostic platform. ····· 1036198578

für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Infrastructure capital can be considered a necessary condition to extend the regional production potential but not automatically a sufficient requirement for enhanced regional competitiveness and income. The materialization of a region`s higher production potential rather relies on the region`s ability to utilize the existing and additional infrastructure capital in an efficient way. Against this background, the paper intends to identify Asian regions` environment with public transport infrastructure and their efficiency in using it. Therefore, the role of transport infrastructure is contrasted with the importance of other region-specific production factors namely educational attainments of the workforce and the availability of modern telecommunication networks. In order to increase the comparability of the regions, the latter are clustered according the land use pattern and industrial structure in a first step. In a second step a quantile regression analysis is performed for each cluster and factor. This, in turn, allows for a sequential bottleneck analysis. This paper explores quantifying the welfare effects of developing regional infrastructure in Asia. ····· 1036198402

The Ethiopian basic metal and engineering industries lack the crucial component of producing basic metals from iron ore or other process route and are still in the infancy stage over the years. However, it s essential for the sector to transfer technology from foreign firms which play a major role in the current endeavor in Ethiopia to bring rapid and sustainable development of the sector. The contribution of FDI to the economy of one country will be effective if and only if there is a local capability to absorb the technology owned by the foreign company to other similar industries which potentially dictates a large scale participation of local personnel s in the FDI companies at a critical level. Though the number of foreign investors currently destined to our country might not be small, but there is less technological flow from foreign investors.

At high temperatures (40 to 60 degree Celsius), bitumen exhibits a viscoelastic behaviour. Pavement made of bitumen may show distress when exposed to high temperatures. At elevated temperatures, permanent deformation or rutting occurs and leads to channels in the direction of travel. This attributed to the viscous flow of the bitumen matrix in paving mixtures, which retains strains induced by traffic. On the other hand, bitumen brittle in low temperature and pavement cracking will occur. Therefore, pavement performance is strongly associated with the rheological properties of bitumen, which can improve by its modification. By adding Oil Palm Fruit Ash (OPFA) as modifier have proofed that bitumen strength and properties improved. OPFA-MB, the binder resulted, resist to the rutting at 70 degree Celsius of pavement temperatures, resist to fatigue cracking at 20 degree Celsius of pavement temperatures, and resist to -16 degree Celsius of pavement temperatures. In addition, OPFA-MB binder have good adhesiveness to bind aggregates. ····· 1036198249· 1 · ::::: · 19 ·· 20 ·· 21 ·· 22 ·· 23 ·· 24 ·· 25 · ::::: · 47 ·
