Abstract:

Angiogenesis, the formation of new blood vessels from preexisting ones through creation of new vessel branch points by sprouting or vessel splitting, is an important part of tissue growth in both physiological processes like wound healing and pathological conditions such as cancer. Growth factors like VEGF-A, FGF-2 and PDGF-BB are involved in both types of angiogenesis. Screening for genes regulated by VEGF-A stimulation in endothelial cells revealed up regulation of the endothelial cell specific glycoprotein endocan. Endocan itself did not stimulate angiogenesis. VEGF was a specific inducer s

Du cerveau à l’os, la rigidité et la composition de la matrice extracellulaire varient énormément et jouent un rôle dans les réponses cellulaires. La rigidité influe également sur la tension de la membrane plasmique, elle-même régulée par le trafic membranaire. Comment la rigidité et la composition du substrat peuvent réguler l'exocytose, qui à son tour régule la tension de la membrane, reste largement inconnu. Ici, j'ai utilisé l’imagerie pHluorin d’évènements uniques d’exocytose de cellules cultivées sur des substrats de rigidité et de composition contrôlée pour explorer la régulation de VAM

This dissertation seeks to understand the conjunction of faculty roles as teachers and as researchers. This understanding is pursued through philosophical analysis. Discourse ethics, in particular, is used as a framework by which to best understand the roles played by faculty and if the roles of teacher and researcher are, in fact, commensurable. The purpose of the work is two-fold: 1) to develop a construct that may be used by future researchers to better understand the roles played by faculty, and 2) to suggest a best-construct that enables future researchers to propose how actual lived role

Abstract:

Management Control Systems (MCS) have been intensively studied in organizational research in the past five decades. Most of existing studies, however, dominantly focus on the traditional control role of MCS. Recently, adequate attentions have been paid to the role MCS for innovation. By recognizing the importance of both control and innovative role of MCS, the MCS researchers have argued that the control and innovative roles of MCS are incompatible with each other. Dynamic tensions exist between them, and how to balance the dynamic tensions of these two contradict roles has emerged as an inter

<p>A baggy paper web has parts that are longer than neighboring parts. One of the assumed reasons for bagginess is thickness variations of the paper. In the roll the thicker streaks then add up to form a ridge. In the ridges the paper is strained and during storage the strain may become permanent. When the paper unreeled it is then baggy. Runability problems because of baggy webs is a common problem in the paper industry. Baggy webs can result in corrugations appearing when the paper is passing through nips during converting processes. Ridges have been simulated in this project by reeling thin

Abstract:

The inflationary paradigm is one which was designed to answer questions that arose from classical Hot Big Bang cosmology. The period of rapid expansion in the early Universe provides a mechanism to solve the flatness, horizon and relic problems. More importantly, since the theory was first introduced it has been realised that it also provides a mechanism to generate the initial perturbations from which structure in the Universe can grow. In the zoo of potential inflationary models there is a dominant class: slow-roll inflation. The idea that the energy density of the inflationary field is domi

Abstract:

Muscle mechanical behavior potentially plays an important role in some of the most common bladder disorders. These include overactive bladder, which can involve involuntary contractions during bladder filling, and impaired contractility or underactive bladder, which may involve weak or incomplete contractions during voiding. Actin-myosin cross-bridges in detrusor smooth muscle (DSM) are responsible for contracting and emptying the bladder. The total tension produced by muscle is the sum of its preload and active tensions. Studies suggest that actin-myosin cross-links are involved in adjustable

For many years, and particularly since the 1980s, the state has taken an interest in the curriculum of state-funded secondary schools.

Against an historic discourse about the nature of art itself and why it is taught and its value in society, the question of 'What is art'? and 'What is the role of the art teacher'? continue to defy a cons

These two kinds of chains are different in both motion and force distributions. Silent chains cause less noise and vibration than roller chains do, and silent chains can be used in higher loading applications. This thesis investigates and compares the motion and force distributions of roller and silent chains. In the study of roller chains, we first investigate geometric constraints and find out contact points between adjacent rollers. Next, we calculate the coord

碩士<br>國立高雄第一科技大學<br>機械與自動化工程研究所<br>103<br>For the steel strip winding, tension control and aligning control in a winding system is important to assure good winding quality. This research proposes a 2 degre-of-freedom intermediate press roller pressing on the constant speed roller to have different front tension and rear tension. The winding system also has the front and the rear aligning control systems. First, the PI controllers are adopted and designed to achieve phase margin more than 60 degee for the tension and aligning control systems. The bandwidth of the front tension control system is

Abstract:

A mathematical model for a Two-Span Web Roller machine is defined in order to facilitate motion planning, motion tracking and state observer design for tracking web tension and web velocity. Differential Flatness is utilized to create reference trajectories that are tracked with a high convergence rate. Flatness also allows for nominal input torque generation without integration. Constraints on the inputs are satisfied through the motion planning phase. A partial state feedback linearization is performed and an exponential tracking dynamic feedback controller is defined.

Title: The effect of foam roller on muscle tone after physical load Objectives: The aim of this thesis was to summarize theoretical knowledge about muscle, changes in muscle tension and possibilities of its affect. The aim of the practical part was to find out the effect of the foam roller on muscle tone after exercise. Methods: Practical part of this thesis was processed in biomechanical laboratory at FTVS UK in Prague and included 16 probands. We measured muscle tone of biceps brachii, m. triceps surae and m. quadriceps femoris before exercise, then the probands performed an activity aimed a

Mean while,since shift correction in transverse direction is usually reguired in high speed winding, multiple rollers between feeding and winding wheels are often included ,which have significant effect in winding tension control. Therefore,this research is aiming at improving the speed/tension control in high speed winding system with multiple rollers. The system dyna

Usually, a levelling process will be adopted to modify the plate flatness. By numerically simulating the tension levelling process, the purpose of this thesis is to understand the final dimensions and the residual stress distribution of the aluminum plate subjected to the tension levelling process. This study used the finite element method as the basic theory of the numeri

Indiana University-Purdue University Indianapolis (IUPUI)<br>Work-life conflict has been repeatedly demonstrated to have a negative impact on individuals and organizations alike. Although the negative impact of work-life conflict has been recognized in the Industrial Organizational Psychology and Organizational Behavioral literature, very few researchers have developed interventions to reduce it. Moreover, the interventions currently in existence tend not to be practical, grounded in relevant theory, or experimentally tested. Thus, the present study sought to create and test an intervention ba
