Shots, Uses, Deployment and Recovery
SHOTS AND DECOMPRESSION RIGS – CONSTRUCTION, DEPLOYMENT AND RECOVERY SHOT USE AND CONSTRUCTION A shot offers the simplest and most direct route from the surface to the seabed. In it’s simplest form is consists of a buoy, line and weight. The buoyancy of the buoy should be sufficient to support the weight. The shot line should be of sufficient strength to support the shot weight, long enough to reach the seabed and be sufficiently thick to aid recovery. Once deployed the shot also offers a surface reference point or datum point from which searches may be conducted. A shot line in some form also offers a stable platform for decompression stops. It is possible to use a boat’s anchor as a shot line however this has several drawbacks. Firstly a cover boat should be mobile at all times. The datum line will not be vertical and the line will alter with the movement of the boat. If the site is environmentally sensitive it may be inadvisable to anchor. As a result of the nature of shot construction it can be seen that the shot line must always be significantly longer than the proposed depth. Once the shot is deployed the excess line will form an angle to the seabed in a current or offer potential entanglement in slack water. There are several ways of tensioning a shot line. Top Tensioned Shot This shot will adjust with the rise and fall of the tide and offers a near vertical descent and ascent. However this configuration is not ideal in strong current or wind. -
Notes on Diving in Ancient Egypt
A Brief History of Underwater Enterprise and Exploration The incentives to risk one’s life underwater from the earliest records of diving: 1) Subsistence and general aquatic harvest 2) Commerce/salvage 3) Warfare A sponge diver about to take the plunge, Classical Greece ca. 500 BCE The beginnings: subsistence in Ancient Egypt: skin divers netting fish in the Nile th Tomb of Djar, 11 Dynasty (ca. 2000 BCE) ‘Pull out well! (It is) a Happy day! Measure you, measure you, for you, good great fishes’ Text and image from the tomb of Ankhtifi (ca. 2100 BCE) The beginnings: other kinds of aquatic/underwater harvest: mother of pearl (left) and sponge diving (right) Mesopotamia (southern Iraq, ca. 2500 BCE) Classical Greece (ca. 500 BCE) The so-called ‘Standard of Ur’: a mosaic of lapis lazuli A sponge diver about to take the (from the exotic region of Afghanistan) and mother of plunge with a knife and a sack, the pearl (from the exotic source of a seabed), deposited in jar was also deposited in an elite tomb an elite tomb in Mesopotamia The beginnings: in search of exotic and high value things (things difficult to access/procure) Epic of Gilgamesh (composed in Mesopotamia no later than ca. 2100 BCE) records a heroic dive after a ‘plant of immortality’ on the seabed ‘He tied heavy stones *to his feet+ They pulled him down into the deep [and he saw the plant] He took the plant though it pricked his hands He cut the heavy stones from his feet The sea cast him up upon the shore’ The value of mother of pearl and sea sponge resides, in part, in the process of procuring them The beginnings: salvaging lost cargoes (lost valuable things) Scyllias and his daughter Hydna: the first professional divers known by name, famed for salvaging huge volumes of gold and silver (tribute and booty) from a Persian fleet in the Aegean that lost many ships in a storm (ca. -

Let Your Light Shine
The Lutheran Beacon Let your light shine . WWW.SELC.LCMS.ORG Published by the SELC District of the Lutheran Church - Missouri Synod MAY 2016 St. John (Cudahy WI) Celebrates Slovak Heritage Celebrating Our Life in Christ by Rev. Carl Krueger St. John, Cudahy WI is celebrating 110 years of Ministry! Founded in 1906 by Slovak Immigrants, St. John “kicked-off” this Anniversary observance year with English/Slovak Communion Worship Services led by the “last-remaining-100% Slovak Heritage-full-time-active- Slovak-Pastors”, and a Slovak menu dinner. At the turn of the 20th Century, Slovakia was ruled by the Hungarian Empire, and subjected to political, social, and religious oppression and persecution. The United States was seen as the land of freedom and opportunity. Slovak men made their way to the Milwaukee area Happy Mother’s Day and found work at the Patrick Cudahy Meat Packing Company May 8th slaughtering and processing beef and pork. The men worked long hours, saved money, then sent for their wives and families. Almost every Slovak adult packed their Slovak Bible and their Slovak Hymnal. First, families found homes, then they sought to establish a Church. “The Slovak Evangelical Lutheran Church of the Unaltered Augsburg Confession, St. John the Baptizer” was founded October 1906, with the city of Cudahy established the same year. The Pastor of a near- by German Lutheran Church provided pastoral care and worship services, along with visiting Slovak Pastors from Chicago IL and Whiting IN. To obtain their own Pastor from the Seminary, St. John needed to join the Slovak Evangelical Lutheran Church (SELC). -

Computational methods such as resampling and bootstrapping are also used when data are insufficient for direct statistical methods. There is little point in making highly precise computer calculations on numbers that cannot be estimated accurately Group Interaction in High Risk Environments 1st edition. Categories : Underwater diving safety. Thus, the surface-supplied diver is much less likely to have an "out-of-air" emergency than a scuba diver as there are normally two alternative air sources available. Methods for dealing with Group Interaction in High Risk Environments 1st edition risks include Provision for adequate contingencies safety factors for budget and schedule contingencies are discussed in Chapter 6. This genetic substudy included Two Sister Study participants and their parents, and some Sister Study participants who developed incident breast cancer invasive or DCIS before age 50 during the follow-up period. In terms of generalizability, our sample is predominantly non-Hispanic white women, and the results may not apply to other racial or ethnic groups. This third parameter may give some management support by establishing early warning indicators for specific serious risks, which might not otherwise have been established. ROVs may be used together with divers, or without a diver in the water, in which case the risk to the diver associated with the dive is eliminated altogether. Suitable equipment can be selected, personnel can be trained in its use and support provided to manage the foreseeable contingencies. However, taken together, there is the possibility that many of the estimates of these factors would prove to be too optimistic, leading. -

2012-13 Swimming Rules Book
2012-13 NFHS SWIMMING & DIVING AND WATER POLO ® RULES BOOK ROBERT B. GARDNER, Publisher Becky Oakes, Editor NFHS Publications To maintain the sound traditions of this sport, encourage sportsmanship and minimize the inherent risk of injury, the National Federation of State High School Associations writes playing rules for varsity competition among student-athletes of high school age. High school coaches, officials and administrators who have knowledge and experience regarding this particular sport and age group volunteer their time to serve on the rules committee. Member associations of the NFHS independently make decisions regarding compliance with or modification of these playing rules for the student-athletes in their respective states. NFHS rules are used by education-based and non-education-based organizations serving children of varying skill levels who are of high school age and younger. In order to make NFHS rules skill-level and age-level appropriate, the rules may be modified by any orga- nization that chooses to use them. Except as may be specifically noted in this rules book, the NFHS makes no recommendation about the nature or extent of the modifications that may be appropriate for children who are younger or less skilled than high school varsity athletes. Every individual using these rules is responsible for prudent judgment with respect to each contest, athlete and facility, and each athlete is responsible for exercising caution and good sportsmanship. These rules should be interpreted and applied so as to make reasonable accommodations for disabled athletes, coaches and officials. © 2012, This rules book has been copyrighted by the National Federation of State High School Associations with the United States Copyright Office. -
Sponges on Coral Reefs: a Community Shaped by Competitive Cooperation
Boll. Mus. Ist. Biol. Univ. Genova, 68: 85-148, 2003 (2004) 85 SPONGES ON CORAL REEFS: A COMMUNITY SHAPED BY COMPETITIVE COOPERATION KLAUS RÜTZLER Department of Zoology, National Museum of Natural History, Smithsonian Institution, Washington, D.C. 20560-0163, USA E-mail: [email protected] ABSTRACT Conservationists and resource managers throughout the world continue to overlook the important role of sponges in reef ecology. This neglect persists for three primary reasons: sponges remain an enigmatic group, because they are difficult to identify and to maintain under laboratory conditions; the few scientists working with the group are highly specialized and have not yet produced authoritative, well-illustrated field manuals for large geographic areas; even studies at particular sites have yet to reach comprehensive levels. Sponges are complex benthic sessile invertebrates that are intimately associated with other animals and numerous plants and microbes. They are specialized filter feeders, require solid substrate to flourish, and have varying growth forms (encrusting to branching erect), which allow single specimens to make multiple contacts with their substrate. Coral reefs and associated communities offer an abundance of suitable substrates, ranging from coral rock to mangrove stilt roots. Owing to their high diversity, large biomass, complex physiology and chemistry, and long evolutionary history, sponges (and their endo-symbionts) play a key role in a host of ecological processes: space competition, habitat provision, predation, chemical defense, primary production, nutrient cycling, nitrification, food chains, bioerosion, mineralization, and cementation. Although certain sponges appear to benefit from the rapid deterioration of coral reefs currently under way in numerous locations as a result of habitat destruction, pollution, water warming, and overexploitation, sponge communities too will die off as soon as their substrates disappear under the forces of bioerosion and water dynamics.
