Bernido and l\faria Victoria Carpio-.Rernido Research Center for Theoretical Physics Central Visayan Institute Foundation Jagna, Bohol 6308, Philippines The Ascending Levels of Learning and Pedagogical ~1axims that could guide effective teaching of physics are presented. As an example of how these may be applied, the Dynamic Learning Prof:,lfam (DLP) of the Central Visayan Institute Foundation is briefly discussed. The DLP, together with 21st century technology, provides a scenario where the perennial lack of high school physics teachers in the Philippines can be bypassed. Introduction The breadth of topics that may be covered in teaching physics can be extremely wide. After all, physics probes the smallest things in the universe (the quarks and leptons), aiJ the way up to the "biggest" subject one can think of-the birth, death, and fate of the universe itself. One definition for physics states that it is the study of matter and energy. Most everything in the universe is either matter or energy, and this can make physics quite interdisciplinary. No wonder, therefore, that sub-areas in physics may be referred to as Biophysics, Geophysics~ Chemical Physics, Mathematical Physics, Astrophysics, Nuclear Physics, Econophysics, etc., and one also has the physics of sports, the physics of art, and so on. Because of its breadth, there is......

...SCI/256: Week 1 NOTES – Environmental Science and Environmentalism ------------------------------------------------------------------------------------------------------------ Environmental Science is the study how humans interact with their environment. Environmental Science is interdisciplinary - brings together information from several physical, biological and social sciences. The main goal of environmental science is to solve environmental problems using science. What is “Natural Environment”? –Environment is our natural surroundings consisting of living and nonliving things. The Earth is part of our environment, comprising 4 “Spheres” Biosphere (living things), Hydrosphere (water), Atmosphere (Air) and Lithosphere (land). Human Impacts: Humans are altering the environment and creating environmental problems. Our main problem involves human population growth and the use of earth’s resources and environmental pollution. Environmental Problems – Examples (a) Depletion of Natural Resources (b) Deforestation (c) Global climate changes (d) Loss of biodiversity (e) Pollution of Air, Water, Land Ecological Footprint is a measure of humanity’s demand on nature. A carbon footprint is "the total set of greenhouse gas (GHG) emissions caused by a person Impacts of Rapid Population Growth: Rapid population growth depletes the Earth’s resources diminishes, quality of life, and damages the environment. Impacts on the environment include, (a) land degradation, (b) air and water......

Lupus

...Lupus, Latin for wolf, is the word used historically to describe any chronic, usually ulcerating, skin disease. Dr. Max Gerson's rise to medical prominence in pre-WWII Germany was owed to the curative effect in lupus vulgaris of a salt-free diet bearing his name. Lupus vulgaris, a European plague of the early part of this century, was tuberculosis of the skin, a bacterial disease that has been largely eliminated through improved public health measures and, to a lesser extent, by antibacterial drugs. Today's lupus is systemic lupus erythematosus (SLE), an inflammatory disorder of connective tissue which frequently targets skin (hence the designation lupus) as well as joints, kidneys, mucous membranes, the nervous system, and virtually any other organ or system in the body. Onset of the disease may be sudden and acute, with fever, painful and swollen joints, skin rash, and influenza-like symptoms; or it may smolder for years with low level malaise and intermittent fevers. Symptoms The list of symptoms attributable to SLE is extensive and astonishing. Among symptoms most frequently observed are painful joints, usually of the hands and feet, which may also include the larger joints. Of all SLE patients, 92% endure significant joint pain. Similarly, 84% of all SLE patients suffer from fevers. Skin eruptions, including round or discoid lesions, as well as a butterfly rash presenting on the cheeks below the eyes and bridging the nose, will afflict 72%. Inflammatory kidney......

Pollution

...Pollution Scenario Review and Summary Week 4 Assignment SCI/256 July 5, 2012 David Pruchenski University of Phoenix Given the budget of $4.4M, the city of Cleveland Hts., has implemented a new bike lane through out the city. This was done in order to encourage it’s residence to be more environmental friendly. Instead of using an automobile everyday, the council felt that with biking, we can decrease the rise of pollution, Exploring ways in which to maximize financial rail performance is thus highly significant for many countries. The need for better and faster transportation is correlated with the economic development of a country (Zahivi, 1981). Train technology has improved immensely over the past few decades and new political developments have led to the desire for building a High Speed Rail network throughout Europe. The aim of this thesis is to show that the limitations of the traditional evaluation techniques also apply to rail system design. In addition, the possibilities of using a flexible approach are explored for the railways. High Speed Rail lines are very controversial. The many opponents of HSR lines emphasize the huge cost and commercial failure rates while proponents see the potential benefits that HSR could bring to a region. A flexible strategy could bring both sides together as it limits the risks and preserves and expands the benefits. 1. Random emission testing:......

With the excessive use of plastics and increasing pressure being placed on capacities available for plastic waste disposal, the need for biodegradable plastics and biodegradation of plastic wastes has assumed increasing importance in the last few years. Awareness of the waste problem and its impact on the environment has awakened new interest in the area of degradable polymers. The interest in environmental issues is growing and there are increasing demands to develop material which do not burden the environment significantly. Biodegradation is necessary for water-soluble or water-immiscible polymers because they eventually enter streams which can neither be recycled nor incinerated. It is important to consider the microbial degradation of natural and synthetic polymers in order to understand what is necessary for biodegradation and the mechanisms involved.......

...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 review of the available literature related to eight distinct areas of tennis-specific recovery. These eight areas are: • • • • • • • • Nutritional Aspects of Tennis Recovery Heat and Hydration Aspects of Tennis Recovery Psychological Aspects of Tennis Recovery Recovery Aspects of Young Tennis Players Physiological Aspects of Tennis Recovery Musculoskeletal Injuries/ Orthopedics...

...these wars. He notes that many of the longest civil wars of the world take place in the context of “sons-of-the-soil” disputes. The hallmarks of these wars are that they are protracted, low in intensity, fought between a government and a peripheral ethnic group seeking autonomy or secession, and the rebels do not view the government as a credible partner in peace talks.

Betting Against Beta

...Betting Against Beta Andrea Frazzini and Lasse H. Pedersen* This draft: October 9, 2011 Abstract. We present a model with leverage and margin constraints that vary across investors and time. We find evidence consistent with each of the model’s five central predictions: (1) Since constrained investors bid up high-beta assets, high beta is associated with low alpha, as we find empirically for U.S. equities, 20 international equity markets, Treasury bonds, corporate bonds, and futures; (2) A betting-against-beta (BAB) factor, which is long leveraged lowbeta assets and short high-beta assets, produces significant positive risk-adjusted returns; (3) When funding constraints tighten, the return of the BAB factor is low; (4) Increased funding liquidity risk compresses betas toward one; (5) More constrained investors hold riskier assets. * Andrea Frazzini is at AQR Capital Management, Two Greenwich Plaza, Greenwich, CT 06830, e-mail: andrea.frazzini@aqr.com; web: http://www.econ.yale.edu/~af227/ .

Bonney Department qf’ Manyfacturing Engineering and Operations Management. Universit.v qf Nottingham, UK Abstract Inventory management is one of the success stories of recent years and it is changing rapidly in response to international competition and new technology. This paper examines some of these developments. Inventory is a major investment in most companies. It strongly influences the internal flexibility of a company, e.g. by allowing production levels to change easily and by providing good delivery performance to customers. Yet inventory ties up working capital and space and it can suffer from obsolescence, deterioration and shrinkage. It can also add to administrative complexity. In recent years attention in manufacturing industry has concentrated on an ‘inventory is waste’ philosophy using JIT production, usually accompanied by visible ‘pull’ or consumer demand driven systems. The approach is also very effective in supermarket retailing and, at its best, provides very high stock turn and high profits to the company at the same time as providing good service and fresh items to customers at low cost, Current changes in inventory management consider the total logistics chain under the term logistics management, place a greater emphasis on purchasing rather than producing in-house and use more international......
