Die Zahnbogenform ist der Bogen, der von den bukkalen und fazialen Oberflächen der Zähne gebildet wird, wenn man sie von ihren Okklusionsflächen aus betrachtet. Die universelle ideale Zahnbogenform ist eine der hartnäckigsten, aber exklusivsten Aufgaben, die die meisten kieferorthopädischen Forscher haben. Was die kieferorthopädische Behandlung betrifft, so besteht das Grundprinzip der Bogenform darin, dass der ursprüngliche Bogen des Patienten im Rahmen der Möglichkeiten erhalten bleiben sollte. Bei der Verwendung von vorgeformten Drähten ist daher zu bedenken, dass deren Form als Ausgangspunkt für die für eine angemessene Individualisierung erforderliche Anpassung betrachtet werden sollte, da alle derzeit verfügbaren vorgeformten Drähte diese Variationen der Bogenform nicht widerspiegeln. Aufgrund dieser komplexen Probleme und des relativ geringen Wissens über Zahnbögen gibt es bis heute keine allgemein akzeptierte ideale Zahnbogenform.

The evidence based research findings of many fields like neuroscience, genetics and psychology, were filtered through the lens of education for exploring new challenges in teaching and learning process and finding ways to solve various educational problems, may it be learning disabilities, motivational problems, retention, development of thinking skills or similar sort of teaching-learning problems. The 7C¿s instructional model has been designed using the principles and instructional guidelines of Mind Brain and Education Science to focus on development of thinking skills among learners. The main objective of 7C¿s instructional model is to make the process of learning more meaningful and interesting to the learners by using positive emotions in teacher-student interactions and creating good learning environment. The effectiveness of 7C¿s instructional model is established in congruence to thinking pattern and parental cognitive stimulation. Thinking pattern has significantly improved with the use of instructional model in teaching Practices.

More and more feature-rich services are being created, and people¿s expectations for quality of experience (QoE) are increasing. The predominant broadband access solutions deployed today are the digital subscriber line (DSL) and community antenna television (CATV) / (cable TV) based networks. However, both of these technologies have limitations because they are based on infrastructure that was originally built for carrying voice and analog TV signals, respectively; but their retrofitted versions to carry data are not optimal. Currently deployed blends of asymmetric DSL (ADSL) technologies provide 1.5Mb/s of downstream bandwidth and 128kbits/s of upstream bandwidth at best. Although variations of DSL such as very-high-bit-rate DSL (VDSL), which can support up to 50Mb/s of downstream bandwidth, these technologies have much more severe distance limitations. Passive optical networks (PONs) have evolved to provide much higher bandwidth in the access network. It is a point-to-multipoint, fiber to the premises network architecture in which unpowered optical splitters are used to enable a single optical fiber to serve multiple premises.

Recording and storing land information in the form of images or videos is one of the major tasks for variety of applications such as mapping terrains, survey programs or monitoring environmental conditions etc. Land data recording is done through remote sensing with the help of satellites or aircrafts. With the increasing demand of storing and sending land images results in lack of sufficient memory spaces and transmission bandwidth. Thus, there is a need of compression technique for efficiently utilizing the storage space and network bandwidth resources. There exist many compression schemes categorized into Lossy and Lossless depending upon the fact of losing some information from reconstructed image or not. Lossy schemes are preferable to those applications that can tolerate some loss and requires higher compression ratios whereas lossless schemes are used for applications that cannot afford a minor loss of information. Over the past few years, lossy compression schemes are under intensive interest because of achieving higher compression ratios. Hence in this work, we have focused on lossy compression schemes.

Dental arch form is the arch, formed by the buccal and facial surfaces of the teeth when viewed from their occlusal surfaces. The universal ideal arch form is one of the most persistent but exclusive task for most of the orthodontic researchers have. Concerning the orthodontic treatment, basic principle of arch form in is that within reason, the patients original arch from should be preserved. Therefore, if the preformed arch wires are to be used, it is to be kept in the mind that their shape should be considered a starting point for the adjustment necessary for proper individualization as all the presently available preformed arch wire do not reflect these variations in the arch form. Because of these complex problems, and relatively low knowledge of dental arches, as of today, there is no universally accepted ideal arch form.

This thesis advances the long-standing challenge of measuring oxidative stress and deciphering its underlying mechanisms, and also outlines the advantages and limitations of existing design strategies. It presents a range of approaches for the chemical synthesis of fluorescent probes that detect reversible changes in cellular oxidative stress. The ability to visualise cellular processes in real-time is crucial to understanding disease development and streamline treatment, and this can be achieved using fluorescent tools that can sense reversible disturbances in cellular environments during pathogenesis. The perturbations in cellular redox state are of particular current interest in medical research, since oxidative stress is implicated in the pathogenesis of a number of diseases.The book investigates different strategies used to achieve ratiometric fluorescence output of the reversible redox probes, which nullify concentration effects associated with intensity-based probes. It also describes suitable approaches to target these probes to specific cellular organelles, thereby enabling medical researchers to visualise sub-cellular oxidative stress levels, and addressing the typically poor uptake of chemical tools into biological studies. In total it reports on four new probes that are now being used by over twenty research groups around the globe, and two of which have been commercialised. The final chapters of this thesis demonstrate successful applications of the sensors in a variety of biological systems ranging from prokaryotes to mammalian cells and whole organisms. The results described clearly indicate the immense value of collaborative, cross-disciplinary research.
