...match or any routine practice. Such routines should include a warm up session that is followed by a stretching session. The warm up session functions to elevate core temperature by engaging in some light calisthenics or light running (White, 2008). In turn, this increases extensibility and flexibility of muscles and tissues. Similarly, the stretching routine also serves to increase the extensibility and flexibility of muscles and tissues. This paper will give the rational for using dynamic stretching, its benefits and the specific movements that one can use during the stretching process. Dynamic stretching is among the preferred stretching techniques used by a majority coaches. It involves the controlled swinging of both arms and legs without stretching out of one’s range of motion. In this case, the stretch is produced by both active muscular contractions and momentum (Reilly, 2007). During dynamic stretching, one uses certain movements depending on their sport in preparation for body movement. This type of stretching tends to be confused with ballistic stretching. This is because if one stretches beyond their static ability, it is no longer dynamic stretching but rather ballistic stretching. This routine of dynamic stretching should begin from low intensity and gradually progress to movements of higher intensity (White, 2008). This is mainly because dynamic stretching calls for both coordination and balance. This form of preparticipation routine serves as an aerobic...

...in my research I found some interesting information in regards to stretching techniques that I and maybe many other people were not aware of. There are seven different types of stretching techniques I specifically decided to focus in on and they coincide with both the upper body and the lower body. The common stretching techniques include: • Static stretching • Ballistic stretching • Proprioceptive neuromuscular facilitation • Active isolated stretching • Dynamic stretching • Passive stretching • Isometric stretching In this paper I will give a brief overview of each of these different techniques and the muscles they target. Static stretching is the most common type of stretching. It is probably the easiest and most useful to do. You gently assume a stretch position and hold it for 30 to 60 seconds. There is no bouncing or rapid movement and you should feel the mild pulling sensation but no pain. Ballistic stretching consists of trying force part of the body beyond its normal range of motion bouncing into a stretched position. An example o ballistic stretching would be bouncing down repeatedly to touch your toes. The key to using ballistic stretching properly is to warm up with mild aerobic activity and then use gentle bouncing motion. The time and repetition guidelines are the same as for static stretching. Proprioceptive neuromuscular facilitation is not really a type of stretching but a technique of combining passive stretching and isometric stretching in order...

...Drop Drag And Spray Models Abstract This paper reviews and critiques the published work of Liu et al, “On modeling the effect of drop drag and breakup on Fuel Sprays”. A dynamic drop drag model (DDM) has been coupled to the (TAB) and (KH) spray models. The interaction the (DDM) with these models provides insight into the phenomenon of drop drag and the atomization process. Due to the interaction of the parent drop during interaction with the spray, it is shown that the KH model must be adjusted to account for drag. The (TAB) model, however, remains unaffected by drag given the formulation of its breakup mechanism. The (DDM) also shows that the standard drag model underestimates drop size. And lastly, a critique of the ineffectualness of drop drag on penetration is presented. Introduction Recent studies estimate that twenty-five percent of the world’s energy comes from fuel spray combustion [4]. Given the impact of sprays on the energy industry, spray optimization is crucial to supply the growing demand for energy. Spray and atomization science developed from the ideas prominent scientist like Rayleigh, Kelvin and Helmholtz who were studying liquid jet break-up mechanisms. All modern models incorporate their work in some way. The field is a conglomerate of studies and insights built on break-up mechanisms, drop dynamics, and spray characteristics but a unified theory of atomization still escapes scientist and research engineers. An often neglected phenomenon is drag...

Ben Kibler, MD A United States Tennis Association Sport Science Committee Project Tennis Recovery: A Comprehensive Review of the Research Copyright © 2010 United States Tennis Association Inc. ISBN 978-0-692-00528-6 Editors: Mark S. Kovacs, Todd S. Ellenbecker, W. Ben Kibler TENNIS RECOVERY A Comprehensive Review of the Research A United States Tennis Association Sport Science Committee Project Editors: Mark S. Kovacs, PhD Todd S. Ellenbecker, DPT W. Ben Kibler, MD Introduction In the last two decades, physical training and competitive opportunities have increased dramatically in junior, collegiate and professional tennis. This arose due to a multitude of factors, but much of it has stemmed from an increase in knowledge and understanding of scientifically based training programs focused on improving performance. As this focus on performance has increased, the area of recovery has received relatively limited focus. Recovery is a multi-faceted paradigm focusing on recovery from training—session to session, day to day and week to week. Recovery is also vitally important during training as well as in competition between matches and between days during multi-day tournaments. As more information is needed in the area of tennis specific recovery, the Sport Science Committee of the United States Tennis Association (USTA) sponsored an extensive evidence-based...

...What are the physical and cognitive benefits of exercise on patients with multiple sclerosis? 1. Bayraktar D, Guclu-Gunduz A, Yazici G, et al. Effects of Ai-Chi on balance, functional mobility, strength and fatigue in patients with multiple sclerosis: a pilot study. NeuroRehabilitation. 2013; 33(3):431-7. This research study was designed to examine the effects of Ai-Chi exercises in a swimming pool on balance and mobility in patients with multiple sclerosis (MS). Poor balance and decreased mobility is a common issue with MS, and the decline often limits daily activities. Researchers recruited twenty-three females affected by MS, and divided them into two groups. The exercise group performed Ai-Chi exercises for a 60 minute session twice a week for eight weeks. The control group did a home exercise program that only involved abdominal breathing and active range of motion exercises. Upon conclusion of the program, subjects were tested on static balance, functional mobility, fatigue, and muscle strength. The exercise group showed significant improvements across all measures, but the control group did not. This shows that the aquatic exercise program is a viable option to combat the negative effects of MS. A strength of this study was the use of aquatic therapy. The researchers stated that although this therapy is widely used, more studies need to be performed to gain more knowledge. Recording results on patients is concrete evidence that these programs work. This study was published...

...Shashvat Jaiswal, Amit Kumar Singh Department of CS/ICT, Jaypee University of Information Technology Abstract--As networking continues to grow exponentially, the Intellectual Property Rights (IPR) can be obtained and reproduced easily. These threats create a high demand for a content protection technique such as digital watermarking; which is one of the most efficient ways to protect the digital properties in recent years. Image watermarking techniques are frequently applied in the transform and spatial domains to achieve desired secure and robust protection. This paper provides an overview of the wavelet-based watermarking techniques available for medical images until now. In this paper the major methods have been analyzed along with their advantages & disadvantages. Keywords: Discrete Wavelet Transform, Medical image watermarking, ROI, NROI, I. INTRODUCTION D igital watermarking has emerged as a research area that was originally focused on copyright protection. Also, it has been implemented in lot of domains, such as video, audio, image, and 3D graphic model. Despite the fact there are only a few medical oriented watermarking studies in the literature to date, digital watermarking will be a valuable tool for copyright protection with medical confidentiality protection, patient and examination-related information hiding, data integrity control and source identification, in Hospital Information System(HIS) and picture archiving and communication system(PACS) based on Digital...

...important educational system in which the library staffs are the key persons in the provision of unquantifiable information services to library patrons and community of users. Poor working conditions affect the physical well-being of the library staffs. In line with this, the researcher attempted to find how the workstations of the library staffs and workers of the seven (7) academic institutions and eleven (11) schools institutions in Angeles City are ergonomically designed. The researcher used the descriptive method and inferential statistics such as T-test to check the significant differences between the library ergonomics of the academic and school institutions and also percentage distribution and weighted mean of the responses of the research respondents. Findings of the study showed that library staffs in both academic and school libraries were not fully ergonomically aware on the different physical factors that strain their bodies when staying in their workstation. The respondents indicated uncertainty on the comfort they have on their workstation. They also indicated that they experienced less stress on the eyes but they experienced much pain on the wrist and neck. These pains that were brought by the unergonomic furniture did not fit the different anthropometric measures of the library staffs that require knowledge and training to correct the unfit furniture. Indeed, it is desirable to fully understand the benefit of taking micro-break, office exercises, and proper arrangement...

...REVISITING MARKET EFFICIENCY: THE STOCK MARKET AS A COMPLEX ADAPTIVE SYSTEM by Michael J. Mauboussin, Credit Suisse First Boston t is time to shift the emphasis of the debate about market efficiency. Most academics and practitioners agree that markets are efficient by a reasonable operational criterion: there is no systematic way to exploit opportunities for superior gains. But we need to reorient the discussion to how this operational efficiency arises. The crux of the debate boils down to whether we should consider investors to be rational, well informed, and homogeneous—the backbone of standard capital markets theory—or potentially irrational, operating with incomplete information, and relying on varying decision rules. The latter characteristics are part and parcel of a relatively newly articulated phenomenon that researchers at the Santa Fe Institute and elsewhere call complex adaptive systems. Why should corporate managers care about how market efficiency arises? In truth, executives can make many corporate finance decisions independent of the means of market efficiency. But if complex adaptive systems do a better job explaining how markets work, there are critical implications for areas such as risk management and investor communications. I Take, for example, the earnings expectations game.1 In a complex adaptive system, the sum is greater than the parts. So it is not possible to understand the stock market by paying attention to individual analysts. Managers...

Abstract This paper presents solutions for one requirement of autonomous characters in animation and games: the ability to navigate around their world in a life-like and improvisational manner. These “steering behaviors” are largely independent of the particulars of the character’s means of locomotion. Combinations of steering behaviors can be used to achieve higher level goals This paper divides motion behavior into three levels. It will focus on the (For example: get from here to there while avoiding obstacles, follow this corridor, join that group of characters...) middle level of steering behaviors, briefly describe the lower level of locomotion, and touch lightly on the higher level of goal setting and strategy. Introduction Autonomous characters are a type of autonomous agent intended for use in computer animation and interactive media such as games and virtual reality. These agents represent a This stands in character in a story or game...

First we briefly review the role of trust. Then we analyze the state-of-the-art of the theoretical and empirical literature on trust creation and antecedents for experienced trustworthiness. As a result of the literature review and our knowledge of the context in praxis, we create a model on organizational trust building where the interplay of inter-organizational and inter-personal trust is scrutinized. Potential challenges for our model are first the asymmetry of organizations and actors and secondly the volatility of the business. The opportunity window for partnering firms may be very short i.e. there is not much time for natural development of trust based on incremental investments and social or character similarity, but so called “fast” or “swift” trust is needed. As a managerial contribution we suggest some practices and processes, which could be used for organizational trust building. These are developed from the viewpoint of large organization boundary-spanners (partner/vendor managers) developing...

...for competitive advantage Introduction There has been a progressive increase in the topic of benchmarking – but for all that there is still a great deal of ignorance about what it actually is. It has taken its place as a management buzzword along with BPR, TQM, Change, EVA and many others – but its true nature is poorly understood. Some see it as stealing (or ‘borrowing’) ideas; others as a mechanism for comparison with a competitor; whilst others view it as a form of industrial espionage. In fact it is all of these and none of these at the same time, but instead involves understanding strategic gaps; cooperation; hard work; a willingness to question and where necessary to change fundamental precepts (sacred cows) and also - giving. This paper will address several issues including: what benchmarking is; when it should be used; and the benefits from using it; how to approach a benchmarking initiative; and how to optimise a benchmarking project. What is benchmarking? The term benchmark comes from surveying where it was used to denote a notch or mark representing a given altitude and against which other heights could be calibrated or ‘benchmarked’, since when it has come to mean any standard against which something is compared; and some of the leading exponents in business include Xerox and GE. In business terms there are numerous definitions of benchmarking, but essentially it involves learning, sharing information and adopting best practices to bring about step changes in performance...

It begins by discussing adoption, contact and the meaning of these concepts. The key findings are then analysed and discussed in correlation to social work practice. From the literature analysed it would seem that direct contact has a positive impact on the challenges facing adopted children. These include, identity development,attachment development and reduced feelings of loss. Recommendation for future practice and research; although there is much to be learnt from research that has been carried out to date, simple formulas and rules cannot be applied; decisions made around contact require case by case assessment of the risks and benefits. Furthermore, long term, large scale research needs to be carried out to examine the effects of direct post adoption contact on children’s lives as they continue to develop and their needs...

Particular interest is also given to interfacial bonding of carbon nano-tubes to polymer matrices as it applies to stress transfer from the matrix to the CNT. Potential topics of oncoming focus are highlighted. 2003 Elsevier Ltd. All rights reserved. 1. Introduction Since the documented discovery of carbon nanotubes (CNTs) in 1991 by Iijima [1] and the realization of their unique physical properties, including mechanical, ther-mal, and electrical, many investigators have endeavored to fabricate advanced CNT composite materials that exhibit one or more of these properties [2,*3,*4]. For example, as conductive filler in polymers, CNTs are quite effective compared to traditional carbon black micro-particles, primarily due to their large aspect ratios [5]. The electrical percolation threshold was recently re-ported at 0.0025 wt.% CNTs and conductivity at 2 S/m at 1.0 wt.% CNTs in epoxy matrices [6]. Similarly, CNTs possess one of the highest thermal conductivities known [*7], which suggests their use in composites for thermal management [2]. The main focus of this paper, however, will be on the use of CNTs...
