A Quick Look at Two Tension Rope System and a Dynamic Directional Offset using Two Artificial High Directionals

Written By: Lance Piatt

The Purpose (Vision)

We have always encouraged experimentation and creativity when learning.  I do my best to take the advice of people I respect.  The other day I sat in the studio thinking about some unused space we have and decided to build a test piece… a small slot canyon where a hiker needed to be removed.  The person fell and was conscious and responsive, but had no way of getting out. Keep it simple, but with broad tangibility.

The Goal or Strategy

Nothing medically wrong… just stuck.  The only real “emergency” I gave myself was one of immediacy due to a lack of daylight and impending colder temperatures.  So… time was critical. The system(s) I wanted to practice needed to be done with minimal people, high points for edge mitigation and a single person load.  My edges were suspect, so keeping the systems and people (me) away from the edge was important.

Now, understanding this setup was a “canyon”, I also understand this can happen “roadside”, so I made this clear on my script, so I chose easier gear options for myself.  The cache was close and I wasn’t super limited in gear (but again, it needed to be super clean and fast), so  I choose gear that would allow me to practice and then scale back after I worked out the kinks.

Also… I would be remiss to say that since this is a practicum for me, I chose to create AHDs (artificial high directionals) with some character.  This scenario is the first of two I built.  In the second option, I created a connective front guy between these same two AHDs.  This “alternative solution” will be discussed later this month or early next month.

Gear and Tools
The Layout or Tactics

I won’t go deep into my process because honestly I am still trying to figure it out.  But essentially I needed a vertical raise straight out of the hole, but had to keep the AHDs away from the edges as the edges were suspect.  I understand (in general principle) that my guy planes and applied force angles had to meet a certain minimum criteria to properly work.  This wasn’t the easiest thing for me to get initially as it ultimately required me to change the leg configurations of the A Frame.  But once I got it (more or less) configured, I was ready to move on.  Here is how I looked at things.

  1. Determine the scope of the evolution (rescue or scenario).
    1. Type of evolution
    2. Type of AHDs needed
  2. Get the AHDs sighted based on the patient and where the exit will be
    1. Determine where the configuration will be placed (where the AHD heads will be)
    2. Determine the guying systems
  3. Get the Anchors prepped and ready
    1. Guying
    2. Raise and Lowering Systems
  4. Determine the systems configured for each AHD
  5. Safety and Check the systems
  6. Begin the evolution and make sure nothing has shifted
  7. Continue running the system and monitor it continuously

This was my system and there are many out there.  It is my intent to bring you a number of opinions and let the dust settle where it may.  And yes… I would alter my “script” as I found a few oversights in it.

The Follow Up

When everything was said and done, the systems were solid.  I checked and double checked the angles of both the A Frame and the opposite Monopod/gin pole.  I was a bit taken back that my angles needed to be “pushed” as far as they were, but they worked perfectly.

The In-line 9 mechanical advantage systems (using 2x Petzl Jags with Petzl Tiblocs) performed amazing.  I had to remind myself that system needs to be performed and monitored by a single person, so it needs to be mirrored and simple… it doesn’t get much simpler.

The dynamic directional from the “far side” exceeded my expectations and my ability to place the patient exactly where I wanted him was a breeze.

Looking forward to bringing you the second half of this “expression session”.

    5. Маска на основе меда и перца. Этот простой рецепт используется для стимуляции кровообращения в области глаз и век, что способствует правильному развитию волосяных фолликул бровей и ресниц. На 4 части меда нужно взять 1 часть красного горького перца, а затем нанести полученную смесь в зоны вокруг глаз. Через 20-30 минут следует стереть остатки маски ватным диском. Если вы уже наращивали ресницы раньше, обращайтесь к проверенному мастеру и проконсультируйтесь по поводу того, какие средства для снятия макияжа лучше использовать в отпуске. Девушкам со светлыми волосами, чтобы избежать вульгарности в образе, следует сначала покрыть ресницы краской, а потом – наращивать. Это создаст плавный переход в цвете и сгладит контраст между ресницами и оттенком волос. Стоит отметить, что любая болезнь, начиная простым ОРВИ и заканчивая обострением хронических недугов, приводит к снижению иммунитета, ослабляя весь организм. Поэтому очень важно принимать витамины для роста бровей и ресниц, которые позволят даже в кризисный для организма период насытить его всеми необходимыми элементами. https://mytenzones.com/community/profile/sonbrumbaugh242/ 9. Жидкая подводка Lumene Blueberry. Это черная подводка для глаз, снабженная удобной кисточкой. Она позволяет создавать самые невообразимые образы. Великолепно подойдет как для опытных, так и для начинающих модниц. Среди оттенков имеется не только черный, но и коричневый цвет. Еще один простой способ для новичков нарисовать стрелку – провести линию так, как получится, а затем подправить погрешности с помощью ватной палочки, смоченной в воде. Средство демакияжа для этого не подойдет — оно растворит пигмент подводки, и стрелка потечет. Арина: «Эту подводку я привозила себе и подругам из-за границы еще до её появления на российском рынке. Могу лишь полностью согласится с Олесей: кисть в комплекте достойная, текстура у подводки — идеальный баланс густоты и цвета, а если вспомнить еще и цену! Линия Glam & Doll, куда входят подводки и туши, бесконечно пополняется новыми вариациями. Водостойкая версия фломастера для глаз вышла недавно и обещает суперпигмент и стойкость 16 часов. У аппликатора форма, как у каблучка kitten heel — широкая сверху и резко сужающаяся к кончику, что дает возможность делать и широкие, и узкие стрелы. Черный цвет действительно очень черный.

Why anyone would ever play American roulette in this situation is beyond us. You are essentially setting money on fire if you choose to play American roulette when European is an option. “That means people are going to play for longer and spend more money in the hopes that the next big win might be around the corner.” The first obvious reason to try any free online Roulette slot is to get to know the game itself. The easiest and fastest way to learn the rules is to learn them during gaming. The great advantage here is that a gambler does not think about money. He can concentrate on the peculiarities of the process without having to think about a loss. This applies to software-based games with RNG. The live games with real croupiers are usually not available as a play money option.

    “Nothing changes overnight if the MORE Act is signed into law because cannabis will still be managed at the state level,” said Jay Czarkowski, founder of Canna Advisors, a Canadian cannabis business consultancy. “Longer term, we’ll see market dynamics of increased competition as those who have been reluctant to enter the industry jump in.” Dan Sutton of Tantalus Labs, a British Columbia-based grower that uses natural sunlight and greenhouses, says legalisation has been “largely negative” for medical cannabis users because of this new sales dynamic: “Physicians have been telling medical users they should buy from the recreational marketplace, which is completely inappropriate – and it loads them up with extra taxes and tariffs.” “It’s concerning that we’re seeing such a dramatic increase,” said Dr. Jeffrey Brubacher (he him), associate professor in UBC’s department of emergency medicine and the principal investigator of the study. “There are serious risks associated with driving after cannabis use. Our findings suggest more is needed to deter this dangerous behaviour in light of legalization.” https://ilikemypc.edunaissance.school/community/profile/delialemieux76/ In the new study the team hunted down the “provider” proteins that trigger antidepressant effects. They first doused multiple mouse brains with different drugs, including LSD, magic mushrooms, serotonin, and a non-hallucinogenic therapy for Parkinson’s disease. They then crystallized the 5-HT2AR “dock” and examined how the chemicals interacted with it at the atomic scale with X-ray beams. The USF study confirms research previously conducted by the Imperial College of London in that psilocybin not only helps patients overcome the so-called “fear conditioning” inherent in PTSD, but also stimulates new brain cell growth. The flow of thoughts and feelings that can flood us every day needs direction. There are different ways in which you can work on the way your brain processes information and your mind thinks about it. Depending on your personal situation, you can take steps to make progress in a healthy functioning brain.
