Conventional heating, a common method used for heterogeneous solid acid catalyst synthesis unknowingly consumes massive time and energy. In this study, acid catalyst was prepared through sulfonation process of incomplete carbonized glucose (ICG) via microwave-assisted technique to shorten the heating time and energy consumption. Optimization of the sulfonation process of ICG via microwave-assisted was carried out. Four-factor-three-level central composite design (CCD) was used to develop the design of experiments (DOE).

A novel two-step heating process, consisting of a short-time high temperature heating followed by isothermal solidification at a lower temperature, was used to transient liquid phase (TLP) bond T91 steel. The interface morphology of the joint was investigated and compared with that of conventional TLP bond made at a constant bonding temperature. The results show that the two-step heating process produces a non-planar interface at the initial stage, which is different from the planar interfaces associated with conventional heating process.

Abstract:
Proteins can be produced by a number of different routes such as fermentation, tissue culture, and by extraction from plasma or plants. Whatever route is chosen, the raw protein-bearing stream is likely to be a complex mixture containing both dissolved species and particulate material. The target protein will be present at very low concentration and with a host of contaminants such as cells or cell debris, DNA, proteins and polysaccharides, and a large quantity of water. Such a mixture is very difficult to treat using the highly selective processes that are required to obtain the target product at high purity since the presence of particulate material impairs their function. The first challenge of protein purification is therefore to convert the complex fermentation broth which is a mixture of dissolved and suspended solids into a form that is amenable to further purification. Although there is much interest in direct recovery of protein from such materials, the most frequent first step currently is to clarify the raw protein source to remove suspended matter. It is then possible to use a range of highly selective techniques to purify the target protein. There are a number of clarification techniques that can be adopted and the choice of which to use depends on both the source of raw feed and the scale of operation. There are two main classes of process; sedimentation and filtration. Sedimentation can be carried out under normal gravity conditions or, as is almost always the case for biological streams, using a centrifuge. Filtration can be performed using either conventional filter media or using membrane filters for removal of finer particles. The aim of this chapter is to describe these methods, and their underlying principles, the advantages of each are discussed, and examples of equipment are presented. Practical advice is presented on how and when to use each technique. Sedimentation processes operate primarily on the basis of density differences between the various components of a mixture. They are most commonly applied to suspensions of solid in liquid, but also to disengage immiscible liquids. If there is no density difference between particulates and the suspending medium, sedimentation cannot occur.

Abstract:
“At the heart of the matter nuclear weapons are simply the enemy of humanity”— retired U.S. Air Force General Lee Butler, former Commander of Strategic Nuclear Forces, spoke these words in his testimony to a 1999 Joint Senate–House Committee on Foreign Affairs. They probably express the deep feelings of most of the world’s people, including most Americans. Towering mushroom blast clouds and the shapes of atomic weapons are common symbols of doom. The specter of nuclear weapons in the hands of terrorists haunts us, and the possibility of attacks on U.S. citizens with “dirty bombs”—a bomb made of conventional explosives that scatters radioactive materials—raises major concerns. As it should. Nuclear weapons and the nuclear waste that they generate truly are destructive to all life and must be controlled. If we fail to prevent their proliferation in the world and stop generating them ourselves, they could destroy us without respect for national boundaries—even without a real nuclear war or dirty bomb terrorist attacks. They already have poisoned great expanses of American lands from coast to coast. American soil, water, and air started accumulating radioactive pollution during the World War II race to build an atom bomb. Radioactive contaminants spread into the environment at every step in the process, from mining the uranium for bomb fuel and purifying and enriching the uranium to make plutonium, to detonating bombs to test them and disposing of the wastes. Radioactive materials currently contaminate buildings, soil, sediment, rock, and underground or surface water within more than two million acres administered by the U.S. Department of Energy in the 11 western states. All sorts of Americans were carelessly exposed to radioactive bomb fuels during WWII and the Cold War, but especially the atomic scientists, uranium miners, and bomb plant workers who were exposed to them every day. For nearly two decades, U.S. atomic bombs blew up and contaminated American lands. Both American soldiers at the test grounds and civilians on ranches or farms and in homes were exposed to the dangerous radioactive fallout (see appendix 5). Perhaps unknown to most Americans is the fact that radioactive contamination from U.S. atomic weapons tests also spread across the whole country and far beyond U.S. borders.

Abstract:
This chapter cites the adoption of Common Article 3 (CA3) as the product of a two-step process characterized by normative pressure and social pressure via forum isolation. It illustrates how the action of the International Committee of the Red Cross (ICRC) was often hindered by government refusal to admit its services or to show humanitarian restraint in internal violence despite the normative inroads made in 1921. It also mentions a new wave of civil war atrocity that was key for slowly generating a shared interest among a majority of states to include humanitarian protections for internal conflicts in the Geneva Conventions. The chapter shows how intense public and private pressures blocked the dismissal of the idea of humanizing internal conflicts and tamed delegates pushing for high conditions of application. It investigates the early Cold War contest between competing liberal and socialist ideologies that accentuated global political status struggles.

Abstract:
Systems such as robotic systems and systems with large input-output data tend to be difficult to model using mathematical techniques. These systems have typically high dimensionality and have degrees of uncertainty in many parameters. Artificial intelligence techniques such as neural networks, fuzzy logic, genetic algorithms and evolutionary algorithms have created new opportunities to solve complex systems. Application of fuzzy logic [Bai, Y., Zhuang H. and Wang, D. (2006)] in particular, to model and solve industrial problems is now wide spread and has universal acceptance. Fuzzy modelling or fuzzy identification has numerous practical applications in control, prediction and inference. It has been found useful when the system is either difficult to predict and or difficult to model by conventional methods. Fuzzy set theory provides a means for representing uncertainties. The underlying power of fuzzy logic is its ability to represent imprecise values in an understandable form. The majority of fuzzy logic systems to date have been static and based upon knowledge derived from imprecise heuristic knowledge of experienced operators, and where applicable also upon physical laws that governs the dynamics of the process. Although its application to industrial problems has often produced results superior to classical control, the design procedures are limited by the heuristic rules of the system. It is simply assumed that the rules for the system are readily available or can be obtained. This implicit assumption limits the application of fuzzy logic to the cases of the system with a few parameters. The number of parameters of a system could be large. The number of fuzzy rules of a system is directly dependent on these parameters. As the number of parameters increase, the number of fuzzy rules of the system grows exponentially. Genetic Algorithms can be used as a tool for the generation of fuzzy rules for a fuzzy logic system. This automatic generation of fuzzy rules, via genetic algorithms, can be categorised into two learning techniques, supervised and unsupervised. In this paper unsupervised learning of fuzzy rules of hierarchical and multi-layer fuzzy logic control systems are considered. In unsupervised learning there is no external teacher or critic to oversee the learning process. In other words, there are no specific examples of the function to be learned by the system. Rather, provision is made for a task-independent measure of the quality or representation that the system is required to learn. That is the system learns statistical regularities of the input data and it develops the ability to learn the feature of the input data and thereby create new classes automatically [Mohammadian, M., Nainar, I. and Kingham, M. (1997)]. To perform unsupervised learning, a competitive learning strategy may be used. The individual strings of genetic algorithms compete with each other for the “opportunity” to respond to features contained in the input data. In its simplest form, the system operates in accordance with the strategy that ‘the fittest wins and survives’. That is the individual chromosome in a population with greatest fitness ‘wins’ the competition and gets selected for the genetic algorithms operations (cross-over and mutation). The other individuals in the population then have to compete with fit individual to survive. The diversity of the learning tasks shown in this paper indicates genetic algorithm’s universality for concept learning in unsupervised manner. A hybrid integrated architecture incorporating fuzzy logic and genetic algorithm can generate fuzzy rules for problems requiring supervised or unsupervised learning. In this paper only unsupervised learning of fuzzy logic systems is considered. The learning of fuzzy rules and internal parameters in an unsupervised manner is performed using genetic algorithms. Simulations results have shown that the proposed system is capable of learning the control rules for hierarchical and multi-layer fuzzy logic systems. Application areas considered are, hierarchical control of a network of traffic light control and robotic systems. A first step in the construction of a fuzzy logic system is to determine which variables are fundamentally important. Any number of these decision variables may appear, but the more that are used, the larger the rule set that must be found. It is known [Raju, S., Zhou J. and Kisner, R. A. (1990), Raju G. V. S. and Zhou, J. (1993), Kingham, M., Mohammadian, M, and Stonier, R. J. (1998)], that the total number of rules in a system is an exponential function of the number of system variables. In order to design a fuzzy system with the required accuracy, the number of rules increases exponentially with the number of input variables and its associated fuzzy sets for the fuzzy logic system. A way to avoid the explosion of fuzzy rule bases in fuzzy logic systems is to consider Hierarchical Fuzzy Logic Control (HFLC) [Raju G. V. S. and Zhou, J. (1993)]. A learning approach based on genetic algorithms [Goldberg, D. (1989)] is discussed in this paper for the determination of the rule bases of hierarchical fuzzy logic systems.

"2. Adhesion of the plasma-polymerized fluorocarbon films to silicon substrates The adhesion properties of the plasma-polymerized FC coatings were determined by using a test, already employed by Yasuda and Sharma [13] (see Fig. 1 and Table 1) in which the silicon substrates coated with plasma FC-films were boiled in a0.9% sodium chloride solution. The FC thin films produced in the processes 1 and 2 were lifted after a very short time (15 minutes). Coatings generated in process 3 were lifted after the second cycle of boiling. The films produced in processes 4 and 5 withstood the complete test procedure. The results are shown in Fig. 3. The poor adhesion of the polymerized films in the first two processes is due to the fact that these processes do not involve a plasma pre-treatment process. The difference between processes 1 and 3 is only in the plasma pre-treatment (process 1 does not contain the pre-treatment step of the silicon surface). The fluorocarbon films deposited by processes 4 and 5 have shown the best adhesion. These test results indicate that the plasma pre-treatment is very important and necessary for a good adhesion of the FC coatings to the silicon surfaces. 2.3. Patterning of FC films 2.3.1. Patterning through resist mask. The patterning of the FC films through a photoresist mask (conventional All resist AR-P351) was examined after deposition for process No. 5. Different coating parameters were investigated to improve the adhesion of the resist to the FC surface. The best adhesion results were obtained using the process parameters, shown in Table 3. Differences in the thickness uniformity of so-deposited resists were in a range below 5%. The samples were etched in a pure oxygen plasma in an RIE-system after the lithography steps (pre-bake, exposure, development, post-bake). A resolution of 2 /xm was obtained. A significant increase in the surface energy was not observed after resist stripping. The sessile contact angle of water was 103°. 2.3.2.
