The competition between national industries and European industries is only possible if the factor quality is preserved and pursued. In this context, the information s concerning each alimentary product are essential to the modern consumer and industries are obliged to accompany these consumers requirements of the final product. This implies that modern industries have to carry out a huge number of chemical dairy analyses to inform correctly the consumers. The majority of classical determinations practiced in dairy products are time consuming The difficulty lies essentially in the laborious sample preparation steps, leading to time-consuming determination. The number of assays practiced in dairy products analysis justifies the introduction of automatic methods in routine laboratory analysis. Considering all these features, the objectives of this work were the development of automatic flow systems (namely flow injection and sequential injection systems) for the determination of different chemical parameters carried out in dairy products. ····· 1036192500

für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray In todays society millions of people go to the movies, rent films and watch TV every day. In science fiction movies, as an audience we have been subjected to the possibilities of technology in the future, products and cities we would only read about in books or see in our own imagination. A definition of science fiction written by H. Bruce Franklin reads, Science fiction is the major non-realistic mode of imaginative creation of our epoch. It is the principle way we locate ourselves imaginatively in time and space. (Franklin H,2009). As early as 1532 trips to the moon were imagined in stories, but as mere fantasy, not a realistic feat for man to ever attain. Many of these stories and fantasies were written about through to the end of the 18th century. It was at the beginning of the 19th century during the start of the industrial revolution and capitalism that modern science was providing the technological means to begin to turn some of these imaginations into a possible reality. ····· 1036192399
für 71.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray This book reports on studies of the synthesis, morphology and the thermal and mechanical characterisation of a range of urethane-acrylic hybrid dispersions. N-methyl pyrrolidone (NMP) was used as a co-solvent in the preparation of some of these polyurethane dispersions (PUDs). NMP is commonly used as a co-solvent in PU coatings as it acts as both a processing and also as a coalescing aid. Environmental legislation will eventually demand its replacement. To this end, NMP was replaced in the synthesis by methyl methacrylate, or styrene. These monomers lead to the formation of urethane-acrylic hybrids. The monomer type and the composition, the glass transition temperature, controlled by copolymerising with n-butyl acrylate, the mode of monomer addition and the synthesis techniques were the main variables studied in this programme. The advantages of these hybrids with respect to latex blend systems were also studied. ····· 1036192286
für 61.20€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Most practical systems and control problems are pure multi-objective problems. Multi-objective or vector-objective optimization problem is characterized by the partial ordering of its solution space. This, unlike in single objective optimization problem, leads to the notion of non-inferiority and the Pareto-optimal solution set. As it has been observed that the vector-optimization problem translates to a scalar optimization problem if a functional that completely orders the solution space can be found. A very important question in the transformation of the vector optimization problem into a scalar optimization problem-form that needs to be answered is that of the equivalence of the scalar problem and the original vector problem. The book proposed a scalarization function which is a sum of squares of the objective functionals. This reduces the vector optimization problem to a quadratic distance problem or the intersection ellipsoid of minimum volume with the trade-off surface. This method has been applied to pure and robust multi-objective Linear Quadratic Regulator (LQR) problem, and to mixed-norm multi-objective problem. ····· 1036192195

für 71.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Wheeled locomotion and legged locomotion have been studied by many researchers with various degrees of detail. On the contrary, the limbless locomotion has drawn very limited degree of interest. In limbless locomotion (of a serpent), the cyclic changes in the body shape is primarily responsible for locomotion. This research considers the development of an experimental serpentine robot for implementation of various serpentine and non-serpentine gaits. It also includes the laying out of serpentine, non-serpentine and synthetic locomotion gaits, including various innovative moves and postures, which were implemented on the serpentine robot. The gait implementation formalism termed as Joint Orientation Function (JOF) is considered as a major contribution of this research. Conventional techniques are limited to demonstrate only few gaits that are highly dependent on the design of specific robot configuration. On the other hand, joint orientation functions are versatile and parametric with limited parameters and can generate wide range of locomotion gaits as well as various static postures. ····· 1036192030

Fundamentals of the NP enrichment mechanism were studied through the calculation of DEP-, and Brownian motion forces. The DEP effective range for Au NP enrichment was determined through the comparison of force magnitude of DEP- and Brownian motion forces. The studied NP enrichment mechanism was then applied to specifically enrich target-oligonucleotides through affinity-binding force. In the experiment, the optimal enrichment condition was found for ultimate sensitivity of the nanotip. In addition, the size-specific enrichment mechanism was investigated through the study of DEP, capillary action, and viscosity. In the experiment, the size-specific enrichment mechanism was verified by using polystyrene nanospheres. As an application study, the NP enrichment mechanism was used to enrich and capture T7 viral particles with a nanotip. The experimental result demonstrated the successful capture of T7 viruses onto a nanotip with an AC electric field. The nanotip-based enrichment method showed the highly sensitive detection of T7 viruses. ····· 1036192018

für 61.20€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Shrinkage cracking can accelerate deterioration of concrete and reduce service life of structures. Numerous techniques have been developed to mitigate the shrinkage cracking of concrete. While influence of these techniques on the cracking performance of concrete mixtures are often evaluated using small scale laboratory geometries, further work is still needed to link the cracking behavior of small laboratory geometries to that of full scale concrete elements. While small scale laboratory geometries such as the ASTM C-1581 restrained ring correspond to a slab of about one meter long, most concrete members of interest in the field are 3-5 meters long. In addition to the dissimilarity in the size, rate of stress development, boundary conditions, and degree of restraint of laboratory geometries can be different from those of in-situ concrete members. This book offers a unique perspective on the influence of these factors on the shrinkage cracking of concrete. The content of this book can be used in interpreting the results of restrained shrinkage testing, designing large-scale shrinkage testing geometries, and estimating the in-situ cracking performance of concrete members. ····· 1036191827
