Introduction
CHAPTER 1: Basic information and techniques INTRODUCTION Fish aggregating devices, or FADs, are floating rafts or buoys anchored in deep water which, for reasons not yet fully understood, cause tuna and other types of oceanic fish to gather around them. FADs were first introduced into Pacific Island countries and territories in the late 1970s, and are likely to be a continuing feature of fisheries development in the region. The introduction and growing use of FADs have opened up new fishing opportunities for the region’s fishermen, but in many cases these have not yet been taken full advantage of. Fishermen are often unaware of the potential yields that can be generated by fishing around FADs, and may not know of suitable fishing techniques or have access to the right gear and equipment. SPC Masterfishermen working on fisheries development projects in the region were some of the first to begin adapting fishing gear and principles to the special conditions of FADs in order to help small-scale fishermen benefit from this new resource. Combining the principles of traditional mid-water tuna handlining and industrial tuna longlining, they began to experiment with multi-hook mainlines set around FADs. These ‘vertical longlines’ were fished directly from the boat, tied off to the FAD, or allowed to drift free suspended from floats or buoys. This gear arrangement simultaneously got numerous baits into the water, focussed the fishing effort close to the FAD, and allowed fishing over a range of depths. Gear used in the early SPC trials was bulky, with mainlines usually being rigged from the 6 or 7 mm tarred Kuralon rope used by large-scale longliners. -
Hollow Braid Eye Splice
The Back Splice A properly sized hollow braid splicing fid will make this splice easier. Hollow braid splices must have the opposing core tucked in at least eight inches when finished. Use discretionary thinking when determining whether or not to apply a whipping to the back splice on hollow braid ropes. 5/16” ¼” 3/16” 3/8” Whipping Twine Hollow Braid Appropriate Sized Knife Splicing Fids STEP ONE: The first step with FIG. 1 most hollow braid splices involve inserting the end of the rope into the hollow end of an appropriately sized splicing fid (Figures 1 & 2). Fids are sized according to the diameter of the rope. A 3/8” diameter rope will be used in this demonstration, therefore a 3/8” fid is the appropriate size. FIG. 2 The fid can prove useful when estimating the length the opposing core is tucked. A minimum tuck of eight inches is required. FIG. 2A STEP TWO: After inserting the end of the rope into a splicing fid (figure 2A) – Loosen the braid in the rope FIG. 3 approximately 10” to 12” from the end to be spliced (figure 3). Approximately 10” to 12” From the end of the rope. Push the pointed end of the fid into one of the openings of the braid, allowing the fid to travel down the hollow center of the braided rope (figures 4 & 5). FIG. 4 FIG. 5 FIG.6 STEP THREE: Allow the fid to travel down the hollow center of the braided rope 8” or more. Compressing the rope on the fid will allow a distance safely in excess of 8” (figure 6). -
BOAT CREW HANDBOOK – Boat Operations
BOAT CREW HANDBOOK – Boat Operations Sumner I. Kimball, USLSS BCH16114.1 December 2017 Sumner Increase Kimball, USLSS A young lawyer from Maine, Sumner I. Kimball was appointed as the chief of the Treasury Department's Revenue Marine Division in 1871. He had joined the Treasury Department as a clerk 10 years earlier and had proven his abilities as a manager. Using his hard-earned political know-how, and a good dose of Yankee common sense, Kimball proceeded to completely overhaul the Revenue Marine and the hodge-podge system of lifesaving stations along the nation's coast that were also under the control of the Revenue Marine Division. His impact on both organizations would prove to be immeasurable. After the Civil War, the Revenue Marine, and the executive branch agencies generally, came under intense Congressional scrutiny. Economy was the name of the game during this time and expenditures were scrutinized across the board. Hence, Kimball decided to order the construction of new cutters not with iron hulls, which entailed considerable expense, but with proven wood hulls. The total number of petty officers and enlisted men was substantially cut and their pay reduced. Kimball also carried out a vigorous "housecleaning" of incompetent Revenue Marine officers and saw to it that discipline was tightened. A special object of his censure was the use of cutters as personal yachts by local Custom officials, a wide-spread abuse during that time. Kimball also put into effect a merit system to determine promotions. He also made one other great contribution to the quality of the Revenue Marine by establishing, in 1877, a School of Instruction, to train young officers. -

Knot Kninja Program V2
TROOP 113 Knot Kninja To Start Everyone will begin at White Cord. You will be given a length of White Cord rope after completing the four requirements for this rank This will be part of your required uniform and should be worn to all scout functions that require a Class A uniform. Advancement In order to advance a level, the participant must demonstrate the knots or techniques listed for that rank and tell how each is useful. There will be a limit of two attempts for each knot. After proving knowledge and ability in a particular level, you will be awarded a length of rope indicating the color you just completed. All Knot Levels must be worn on the belt or belt loop. Knot Masters or Black Cord Knotters may wear theirs as a Solomon Bar or Bugle Cord or any other decorative knot. If you are the first person to achieve that level, testing for that level will be done with at least one Scout and one Scouter and you will provide documentation as to what the finished knot looks like and it’s uses. The advancing Knotter may not view the documentation during the test. Testing Testing will be allowed 15minutes before and 15 minutes after each scout meeting or during the meeting as time allows. Testing may also be done at campouts. You may only test one time per day. Challenges Any Scout or adult may challenge another scout or adult at the same level or below. At that point, the challenger names any two (2)knots from the current rank and below. -
Students Will Learn About Different Types of Knots and Their Uses in an Outdoor Setting. Students Will Practice Creating Each Knot and Master at Least One
Knots Students will learn about different types of knots and their uses in an outdoor setting. Students will practice creating each knot and master at least one. Students will make a paracord bracelet. Materials Included in the Kit: Not Included in the Kit: • 7ft length of paracord • Scissors • Side button buckle • ADULT SUPERVISION - Lighter Lesson Knots are bumps in a rope. These bumps can be made in all different shapes and sizes BUT, they also can be used for a lot of different things! Can you think of activities that we do that we need knots? We use them almost every day putting on shoes for sure. Survivalists and naturalists also use knots when camping, boating, and fishing. Doctors use even use them in surgeries! Each type of knot has its own special job and today we are going to learn about four knots and practice them. Activity 1: tying four basic knots You can follow step by step through each knot following the instructions on the last pages of the lesson 1) Let us start with one of the most simple knots out there - an OVERHAND KNOT. It will look familiar to you, what do you use this one for…tying your shoes? 2) A SLIP KNOT forms an adjustable loop or noose at the end or middle of a rope. You can place the loop around a support and then tighten the knot by sliding it. This makes it simple attaching a line to a bar or post. 3) If you want to tie your fishing line securely to a hook, swivel or lure, the IMPROVED CLINCH KNOT would be your best bet. -
Knot Masters Troop 90
Knot Masters Troop 90 1. Every Scout and Scouter joining Knot Masters will be given a test by a Knot Master and will be assigned the appropriate starting rank and rope. Ropes shall be worn on the left side of scout belt secured with an appropriate Knot Master knot. 2. When a Scout or Scouter proves he is ready for advancement by tying all the knots of the next rank as witnessed by a Scout or Scouter of that rank or higher, he shall trade in his old rope for a rope of the color of the next rank. KNOTTER (White Rope) 1. Overhand Knot Perhaps the most basic knot, useful as an end knot, the beginning of many knots, multiple knots make grips along a lifeline. It can be difficult to untie when wet. 2. Loop Knot The loop knot is simply the overhand knot tied on a bight. It has many uses, including isolation of an unreliable portion of rope. 3. Square Knot The square or reef knot is the most common knot for joining two ropes. It is easily tied and untied, and is secure and reliable except when joining ropes of different sizes. 4. Two Half Hitches Two half hitches are often used to join a rope end to a post, spar or ring. 5. Clove Hitch The clove hitch is a simple, convenient and secure method of fastening ropes to an object. 6. Taut-Line Hitch Used by Scouts for adjustable tent guy lines, the taut line hitch can be employed to attach a second rope, reinforcing a failing one 7. -
Laser Cut Tubing White Paper
J A N U A R Y 2 0 2 0 Enhanced catheter performance made possible with laser cut tubing P R E P A R E D A N D P R E S E N T E D B Y KEVIN HARTKE, CHIEF TECHNICAL OFFICER, RESONETICS Introduction E V O L U T I O N O F L A S E R C U T T U B I N G Laser cut tubing (LCT) uses a focused laser to melt or ablate through one wall of a metal or polymer tube and remove the degraded material via a high-pressure coaxial gas nozzle. The process has been used in medical device manufacturing for over 30 years with major advancements following the push for miniaturization for minimally invasive procedures. For catheter delivery systems, this process has been too slow and costly to incorporate. However, Resonetics has combined advances in laser and motion control to develop a cost- effective tool for high-volume manufacturing of catheter components. This high-speed laser cutting process is branded as PRIME Laser Cut and this paper details: PRIME Laser Cut benefits How to specify laser cut tube Cost savings considerations 0 2 Prime performance benefits L E S S I N V A S I V E P R O C E D U R E S C O N T I N U E T O A D V A N C E , R E Q U I R I N G B E T T E R T O O L S T O E N A B L E A C C E S S . -

What Is a Braid Group? Daniel Glasscock, June 2012
What is a Braid Group? Daniel Glasscock, June 2012 These notes complement a talk given for the What is ... ? seminar at the Ohio State University. Intro The topic of braid groups fits nicely into this seminar. On the one hand, braids lend themselves immedi- ately to nice and interesting pictures about which we can ask (and sometimes answer without too much difficulty) interesting questions. On the other hand, braids connect to some deep and technical math; indeed, just defining the geometric braid groups rigorously requires a good deal of topology. I hope to convey in this talk a feeling of how braid groups work and why they are important. It is not my intention to give lots of rigorous definitions and proofs, but instead to draw lots of pictures, raise some interesting questions, and give some references in case you want to learn more. Braids A braid∗ on n strings is an object consisting of 2n points (n above and n below) and n strings such that i. the beginning/ending points of the strings are (all of) the upper/lower points, ii. the strings do not intersect, iii. no string intersects any horizontal line more than once. The following are braids on 3 strings: We think of braids as lying in 3 dimensions; condition iii. is then that no string in the projection of the braid onto the page (as we have drawn them) intersects any horizontal line more than once. Two braids on the same number of strings are equivalent (≡) if the strings of one can be continuously deformed { in the space strictly between the upper and lower points and without crossing { into the strings of the other.
