Leo Frobenius’ Secret Mission in Arabia and Eritrea (1914–1915)
Authors: Da Riva Rocío , Biocca Dario
Published: September 2016

This article is devoted to study the mission undertaken by ethnologist Leo Frobenius (1873–1938), who, in 1914–1915 and as a member of a German research expedition, attempted to reach Abyssinia (modern-day Ethiopia) through Anatolia, Syria, Palestine, Arabia and Eritrea, in order to liaise with the isolated German Legation in Addis Ababa and to spread revolution among the Muslim subjects of the British Empire in Arabia and in North Africa. The expedition, officially called “Fourth German Inner African Research Expedition”, was in truth a somewhat poorly organised political mission supported by the German and Turkish secret services, and in the end failed to achieve any of its strategic objectives.
Nanobiotechnology and Therapeutics
Authors: Vikrant
Published: September 2016

Nanobiotechnology deals with the application of the tools and processes of nanotechnology to build devices for studying and manipulating biological systems. Current approaches of diagnosis and treatment of various diseases, especially cancer have major limitations such as poor sensitivity or specificity and drug toxicities respectively. Novel and improved methods of cancer detection based on nanoparticles are required to be developed. Some of the nanoparticles used for diagnostic purposes are paramagnetic nanoparticles, quantum dots, nanoshells and nanosomes. Drugs with high toxic potential like cancer chemotherapeutic drugs can be given with a better safety profile with the utility of nanotechnology. These can be made to act specifically at the target tissue by active as well as passive means. Simultaneously, other alternative ways of therapy such as heat induced killings of cancer cells by nanoshells and gene therapy are also being developed. Thus, it indicates that nanomedicine in future would play a crucial role in the treatment of human diseases.

Nanoparticles synthesis using microorganisms and others as source has been unexplored and underexploited. The development of green processes for the synthesis of NP is evolving into an important branch of nanotechnology. Fungal endophytes are microorganisms that colonize living, internal tissues of plants without causing any immediate, overtly negative effects, Endophytic fungi are ubiquitous in plant species and are mutualistic to their host, recently, endophytic fungi have been recognized as important sources of a variety of structurally novel active secondary metabolites with anticancer, antimicrobial and other biological activities, Endophytic mediated synthesis of metal nanoparticles is gaining more importance owing to its simplicity, rapid rate of synthesis of NP of attractive and diverse morphologies and elimination of elaborate maintenance of cell cultures and ecofriendliness. Presently, the researchers are looking into the development of cost-effective procedures for producing reproducible, stable and biocompatible metal NPs.
Nanoencapsulation of Food Ingredients
Authors: Shah Manzoor Ahmad , Mir Shabir Ahmad , Bashir Mudasir
Published: September 2016

Nanoencapsulation of food ingredients is one of the important applications of food nanotechnology. Nanoencapsulation is a technique used to produce nanocapsules from core materials packed within a wall material. Food manufacturers need to incorporate food ingredients with specific functional properties into food products. However, these ingredients may slowly degrade and lose their activity, or become hazardous due to various chemical reactions. They can also react with other components in the food system, which may lower their bioavailability, or change the color or taste of a product, allowing the food item to become prone to spoilage and deterioration. The protection of food ingredients against degradation and interaction with other food components may be done using the nanoencapsulation technique. It also, helps to enhance the bioavailability of food ingredients by protecting them during the digestive processes, improved uptake in the gastrointestinal tract and enhanced transport to the target sites. Nanosized materials provide a larger surface area for interaction with the biological substrates than microsized materials. Various techniques such as emulsification, coacervation, nanoprecipitation, solvent evaporation, spray drying and freeze drying are widely used techniques for nanoencapsulation of food ingredients.
The Impact of Nanotechnology on Environment
Authors: Jayavarthanan Rathinasabapathi , Nanda Anima , Bhat M. Amin
Published: September 2016

Nanotechnology is an emerging field that covers a wide range of technologies which are presently under development in nanoscale. It plays a major role in the development of innovative methods to produce new products, to substitute existing production equipment and to reformulate new materials and chemicals with improved performance resulting in less consumption of energy and materials and reduced harm to the environment as well as environmental remediation. The environmental impact of nanotechnology is the possible effects that the use of nanotechnological materials and devices will have on the environment. This impact can be split into two aspects: the potential for nanotechnological innovations to help improve the environment (beneficial part), and the possibly novel type of pollution that nanotechnological materials might cause if released into the environment (harmful part). The nanoparticles can be used an individual product in pure form or as an adjuvant with existing products in order enhance their activities. The beneficial aspects of nanoparticles include water filtration and treatment, green energy synthesis, degradation of plastics, detoxification harmful dyes and chemicals. The harmful aspects consist of unwanted by-products of nanoparticles, effluents of nano industries, etc.

Published: September 2016

This chapter deals with the applications of gold nanoparticle in cancer and various strategies to target cancer cells by using gold nanoparticles. They are in great demand for biomedical applications such as DNA/Protein detection, bimolecular regulators, cell imaging and cancer cell diagnostics. The ability to tune the surface of the particle provides access to cell –specific targeting and controlled drug release. Depending on their size, shape, degree of aggregation, and local environment, gold nanoparticles can appear red, blue, or other colors. The novel drug delivery systems offer the opportunity to improve poor solubility, limited stability, bio distribution, and pharmacokinetics of drug as well as offering the potential ability to target specific tissues and cell types. The multifunctional gold nanoparticles are attractive organic –inorganic hybrid material composed of an inorganic metallic gold core surrounded by an organic or bimolecular monolayer they provide desirable attributes for the creation of drug delivery in cancer.
Role of Bioinformatics in Nanotechnology
Authors: Anandaram Harishchander
Published: September 2016

Recent advancements in bio-computing and nano-technology accelerated the discovery of novel biomarkers in the emerging field of personalized medicine. Personalized medicine deals with disease detection and therapy from the molecular profile of each individual. Personalized medicine is also called as predictive medicine that uses genetic/molecular information to predict disease development, progression, and clinical outcome. In this chapter, we discuss the advantages of using nanotechnology to understand biological systems with an example of the biomarker discovery of cancer. Recent developments in bio computing served as the base for the identification of multiplexed probes in a nano particle. Together we have correlated the bio molecular signatures with clinical outcomes and we have also addressed an emerging field called bio-nano-informatics to suggest an individual therapy for cancer and other diseases.
The Case Study
Authors: Brady Joseph
Published: September 2016

Today's complex and global corporate environment requires business students to enter the workplace with more diverse skills and the ability to make useful decisions in their careers. The old adage of speaking “to” students in a classroom through straight lecturing is becoming less relevant in today's dynamic world. Rather, students must be engaged in the classroom and educators should provide the opportunity to enhance their decision making skills through real world problem solving. One way to do this is through the methods of active teaching and the utilization of case studies. Case studies are a story, or a narrative, that can induce higher critical thinking and engagement in the classroom and can prepare students for their careers by helping them make real world decisions in a simulated environment. This chapter focuses on the fundamental differences between traditional, lecture-based teaching and the importance of active learning in higher education.
Case Study Method in Simulation Game Design and Teaching
Authors: Wardaszko Marcin
Published: September 2016

Case studies and simulation games have a lot in common. In this chapter, the author analyses the commonalities of case studies and simulation games in three different aspects. The first aspect is the use of simulation games as case study based simulation games for teaching and learning, which are essential parts of simulation and gaming. The second aspect is designing case-study-based simulation games for educational purposes. The third aspect is using case-study-based simulation games in organisational development to increase the effectiveness of organisations and cultural changes. In order to help to design the appropriate learning experience, the author proposes a new game classification related to rule rigidity and win-state conditions, which will help the designers in their task of designing the proper case-study-based simulation game.
Combining Case Teaching and Case Writing Creatively
Authors: Müller Urs , Kupp Martin
Published: September 2016

In this chapter, the authors propose that not only do case teaching and case writing belong together, they can also support and inform each other in many ways. The authors highlight the fact that case teaching and case writing are not two separate and independent tasks, and therefore they should be combined continually in new and creative ways. Although it is obvious that it does not make a lot of sense to write cases without there being a teaching need, the authors argue that educators can start teaching the case even before writing it, and by doing so improve their writing. Many examples are given on how case teaching can be used for case writing, and vice versa.
“Case Writing Canvas”
Authors: Olejniczak Tomasz
Published: September 2016

The popularity of case-study methods in business education is constantly growing. Consequently, there is an increasing demand for publications concerning case writing and teaching, which helps business educators develop their own case studies that fit their local context. However the process of case development remains a kind of ‘black-box' process that requires a combination of diverse perspectives, including theory, writing, and teaching. The aim of this chapter is to review some of the most popular case-development tools and present an idea for a new comprehensive tool, i.e. ‘Case Writing Canvas'. This chapter presents this tool using an example of an actual case, and discusses its usefulness in the context of existing tools, as well as its advantages observed when used for business education in Central and Eastern Europe.

Authors: Starostka Justyna , Kurzyk Bartłomiej
Published: September 2016

The main aim of this chapter is to provide the reader with knowledge about best practices in writing case studies. Case studies are now widely used in many areas of education. Our special focus of this chapter is on business case studies, specifically developed for business school students. Such cases were popularized by Harvard Business School, where this is the main form of teaching. However popular in the teaching process, writing case studies can post significant challenges, especially to first-time case writers. This chapter aims to address those challenges that may occur while developing a case study and to provide the reader knowledge about the best practices in writing case studies. The authors believe that this material can be useful for both experienced case study writers and those with no practice or prior experience. This chapter contains three sections. The first part is focused on the case study development process, covering four stages: strategic decisions, research, writing, testing and refining. The second section aims to present practical aspects of writing a good case study and best practices for case study content and the main elements of case study structure. The third section is focused on a teaching note in the case study development process. In the appendinx the authors present the checklist for developing a good case study that can be helpful tool in the development process.
Security, Privacy, and Trust for Pervasive Computing Applications
Authors: Ahamed Sheikh I. , Zulkernine Mohammad , Haque Munirul M.
Published: September 2016

Pervasive computing has progressed significantly during this decade due to the developments and advances in portable, low-cost, and light-weight devices along with the emergence of short range and low-power wireless communication networks. Pervasive computing focuses on combining computing and communications with the surrounding physical environment to make computing and communication transparent to the users in day-to-day activities. In pervasive computing, numerous, casually accessible, often invisible, frequently mobile or embedded devices form an ad-hoc network that occasionally connects to fixed networks structure too. These pervasive computing devices often collect information about the surrounding environment using various sensors. Pervasive computing has the inherent disadvantages of slow, expensive connections, frequent line disconnections, limited host bandwidth, location dependent data, and so forth. These challenges make pervasive computing applications more vulnerable to various security-related threats. However, traditional security measures do not fit well in pervasive computing applications. Since location and context are key attributes of pervasive computing applications, privacy issues need to be handled in a sophisticated manner. The devices in a pervasive computing network leave and join in an ad-hoc manner. This device behavior creates a need for new trust models for pervasive computing applications. In this chapter, we address the challenges and requirements of security, privacy, and trust for pervasive applications. We also discuss the state-of-the-art of pervasive security, privacy, and trust along with some open issues.
Responsibility for Information Assurance and Privacy
Authors: Stahl Bernd Carsten
Published: September 2016

Decisions regarding information assurance and IT security can affect individuals’ rights and obligations and thereby acquire a moral quality. The same can be said for questions of privacy. This article starts by showing how and why information assurance and privacy can become problems worthy of ethical consideration. It demonstrates that there is no simple and linear relationship between ethics and information assurance, nor between ethics and privacy. Many decisions in the area of IT, however, affect not only one but both of these subjects. The ethical evaluation of decisions and actions in the area of privacy and security is therefore highly complex. The article explores the question of whether individual responsibility is a useful construct to address ethical issues of this complexity. After introducing a theory of responsibility, the article discusses the conditions that a subject of responsibility is typically assumed to fulfil. The article will argue that individual human beings lack some of the essential preconditions necessary to be ascribed responsibility. Individuals have neither the power, nor the knowledge, nor the intellectual capacities to successfully deal with the ethical challenges in the tension of privacy and information assurance. The article ends by suggesting that the concept of responsibility may nevertheless be useful in this setting, but it would have to be expanded to allow collective entities as subjects.
A Theoretical Model and Framework for Understanding Knowledge Management System Implementation
Authors: Butler Tom , Heavin Ciara , O’Donovan Finbarr
Published: September 2016

The study’s objective is to arrive at a theoretical model and framework to guide research into the implementation of KMS, while also seeking to inform practice. In order to achieve this, the paper applies the critical success factors (CSF) method in a field study of successful KMS implementations across 12 large multinational organisations operating in a range of sectors. The paper first generates a ‘collective set’ of CSFs from extant research to construct an a priori model and framework: this is then empirically validated and extended using the field study findings to arrive at a ‘collective set’ of CSFs for all 12 organisations. These are then employed to refine and extend the theoretical model using insights from the literature on capability theory. It is hoped that the model and framework will aid theory building and future empirical research on this highly important and relevant topic.
Balancing Local Knowledge Within Global Organizations Through Computer-Based Systems
Authors: Joshi Somya , Barrett Michael , Walsham Geoff , Cappleman Sam
Published: September 2016

This article investigates how, and with what success, global organisations design computer-based systems for knowledge sharing which aim to balance centralised and standardised approaches against more diverse local needs. The empirical basis for the article is provided by an analysis of two different global organisations, each with its own knowledge-sharing infrastructure in place. We use third-generation activity theory as the theoretical basis for our analysis. The contributions from this article are twofold. The first is our theoretical lens, where activity theory is applied to the domain of global information systems and their organisational context. This analysis provides a new approach in addressing both the mediation of and motivations behind knowledge-sharing activity. The second contribution concerns the theoretical and practical insights this gives on the problems and challenges of achieving a balance between global and local priorities within highly distributed work contexts, and the role of computer-based systems in this arena.
Evaluating Conceptual Modelling Practices
Authors: Shanks Graeme , Nuredini Jasmina , Weber Ron
Published: September 2016

This chapter examines how ontological theory can be used to predict how alternative conceptual modelling representations affect end-user understanding of these representations. Specifically, it examines how ontological theory can be used to show how part-whole relations (composites) and things and properties can be best represented to enhance understanding of these real-world phenomena. We report the outcomes of two experiments that provide evidence to support the ontologically sound representation of partwhole relations and things and properties. We also discuss the outcomes of a cognitive process tracing study that explains why the ontologically sound representation of things and properties is more easily understood. In essence, our empirical research provides evidence to support the use of ontology as a theoretical basis to guide conceptual modelling practices.
Growing Systems in an Emergent Organization

Published: September 2016

The degree of organizational change is reaching a frenzied pace. Organizational change is currently driven by the rapid development of commercial technology, global markets and reengineered, quality-oriented organizations. This constant need to change gives rise to a recognition that human organizations in the current era are no longer stable, but are continuously adapting to their shifting environment. These organizations can be said to be in a state of constantly seeking stability, while never achieving it. Such organizations are said to be “emergent,” and include many of today’s commercial and government organizations.

Photocatalytic Effect of Metal Oxide Nanoparticles on Cultured Human Breast Cancer Cells
Authors: Suanlim Ladawan , Srivatcharakul Suttijit , Locharoenrat Kitsakorn
Published: September 2016

We have studied the photocatalytic effect of ZnO, TiO2 and CuO nanoparticles under the different wavelength of the light irradiation on the cultured human breast cancer cell line. Each nanoparticle under the different wavelength of irradiation on the cells shows the different cell-killing effect. It is found that ZnO nanoparticles irradiated under the ultraviolet C are more pronounced toxicity than CuO nanoparticles irradiated under the visible light, and TiO2 nanoparticles irradiated under the ultraviolet A, respectively. The intimate contact between the cell wall and the metal oxide nanoparticles under the appropriate light irradiation causes the changes in the environment in the vicinity of cell-nanoparticles contact area. This can generate the intracellular reactive oxidation species, partly due to the electron-hole pair, that tends to damage the nucleus of the cancer cells.
Numerical Simulation Research on Springback Controlling Methods of Aluminum Alloy Panel during Hydroforming
Authors: Lin Dong Yan , Li Yi
Published: September 2016

The hydroforming process of the aluminum alloy panel was simulated by the software DYNAFORM. The effects of process parameters (blank holder force, depth of panel and height of draw bead) on springback of the aluminum alloy were investigated. The max springback of the panel was analyzed by weighted scoring method. Then the process parameters were synthetically optimized for the max positive and negative springback. The results showed that the height of draw bead affects obviously the comprehensive springback of the panel. The optimization of the process parameters obtained by the orthogonal experiment can effectively reduce the max springback of the panel.

Published: September 2016

This paper presents the design, build and performance test of a solar tunnel dryer combined heat with a parabolic trough for paddy drying. A 2.27 m² parabolic trough stainless steel made with a single-axis solar tracking system produced hot water and delivered to the cross flow heat exchanger equipped with a solar tunnel dryer with the size of flat plate collector of 2.112 m2. The system received solar radiation and reflected sunlight to the receiver at the focal point of a parabolic trough. At this point, a copper heat pipe with the inside diameter of 25.4 mm for water heating is placed. A parabolic trough is covered with plastic sheets for protecting the wind in order to prevent the heat loss by convection. The produced hot water is used to warm the air and is sent to the heat exchanger and the blower passes hot air through the drying chamber of solar tunnel to dry paddy. The average drying temperature was 57.73 °C. The paddy moisture content was assessed in a reduction from 49.96 to 15.61 MC (% d.b.) in 6 hours. The heated air was around 245.87 W, with the incoming heat in the solar tunnel dryer of 1271.84 W. The thermal efficiency of a solar tunnel dryer, a parabolic trough, and the overall efficiency were on the average of 28.31%, 8.73%, and 3.80%, respectively.

An Evaluation of the Nominal Stress Method for Life Prediction of Cylindrical Circumferential V-Notched Specimens Tested under Variable Amplitude Loading
Authors: Duran Jorge Alberto Rodriguez , da Costa Dionisio Jose Rodrigues
Published: September 2016

An experimental device was constructed with the aim of testing various cylindrical V-notched specimens until fracture and under variable amplitude torsional loads. The specimens had different notch depths resulting in the same number of values for the stress concentration factor. Strain gages directly bonded at the specimens’ surface and using a slip ring system for their communication with the conditioner, allowed the measurement of the actual applied loads. The well-known rain flow cycle counting procedure was then applied on the scaled signal for identifying the frequency of the 64 classes of stress amplitudes and means. The traditional nominal stress-based approach was then evaluated as the most widely used tool for fatigue lifetime calculations. As the occurrence of stress amplitudes above the endurance fatigue limit tends to lower it, the Miner elementary method was used. The results show damage sum ranges between 0.5 and 6.4 with a mean value of 2.0. Despite the small size of the sample used in the present paper (only 13 tests), these significant deviations are in agreement with previous results reported by different researchers.

The time independent modified Reynolds equation, elasticity equation and the load capacity of asperities equation were numerically solved using finite different method, Newton-Raphson method and multigrid multilevel methods to obtain the film pressure profiles, film thickness profiles and contact pressure in the contact regions. The simulation results showed that the the amplitude of surface roughness has a significant effects on the film pressure, film thickness and surface contact pressure in the contact region. The minimum gap between surface, friction coefficient and asperity load increase when the amplitude of surface roughness increases. For increasing surface velocity, the minimum gap between surface increases but asperity load decreases.

This paper the properties of heat-shrink tubing, cold-shrink tubing and prefabricated type cable accessories are studied. And based on that, we make a contract with the composition of the material, processing technology and respective advantages. We found that heat-shrink tubing is the most widely use in the electric power system, which has the advantage of low price, simple machining technology and wide source of raw materials. The major characteristic of cold-shrink tubing is easy to install without heating, which is superior to heat-shrink tubing. In addition, excellent physical properties and high contraction rate are also the reflection of its advantages. The prefabricated type cable accessories, as the latest products, have good use foreground because of the resistance to interference and the convenience.

We investigated some properties of Y134 superconductor doped Ti superconductor. The series of samples of Y134 doped Titanium (YBa3Cu4TixO9-δ) which x=0, 0.05, 0.10, 0.15, 0.20, 0.25 were prepared by solid state reaction method with calcinations and sintering temperature at 980 °C. The porosity was reduced and the melting area were found for all Ti-doped samples. There was a little effect of Ti-doped on Tc onset but the lower of Tc offset were found that agree with the melting found on surface of sample with Ti-doped. The peritectic temperature of Y134 powder, and Y134 + 0.10Ti were on the same range about with more peak area of pure Y134 than Y134 with Ti-doping.

To ensure the machining precision of work piece and improve the machining quality and machining efficiency, a dynamic transition method based on axial machining accuracy is given. Firstly, the maximum machining contour error is computed based on the axial machining accuracy, and the tool path is processed based on the machining contour error to reduce the amount of command points. Secondly, the circle transition method is used to make the tool path smoother and the machining efficiency higher. Finally, the radius of the transition circle is adjusted based on the maximum velocity of each transition circle. The experimental results shows that the method proposed could effectively satisfy the needs of the machining accuracy and improve the processing efficiency, while reduce the amount of path data.

Testing and Analysis of Micro-Vibrations Generated by Control Moment Gyroscope in Different Installation Boundary
Authors: Li Xiong Fei , Cheng Wei , Li Ming
Published: September 2016

The micro-vibrations caused by CMG (Control Moment Gyroscope) can seriously degrade the pointing accuracy and imaging quality of spacecraft. To test the micro-vibrations generated by CMG and obtain the corresponding frequency spectrum characteristics is the key to design the vibration restraining and analyze the vibration transfer properties. In order to simulate the actual installation boundary of CMG on spacecraft, a flexible interface is designed to compare with the rigid interface in traditional testing methods. The results show that: due to the existence of coupling effect between the CMG structure and the flexible interface, the traditional rigid interface is unable to predict the disturbance emitted by CMG in the installation boundary of spacecraft accurately. To study the micro-vibrations produced by CMG in the installation boundary of flexible interface is of great significance.
