We spend 20 minutes at 30m, how much air do we use?Īscending from the dive, you have two options when it comes to calculating the air used during the ascent. We spend 15 minutes at 10m, how much air do we use? (SAC = 25 lpm) Lets take a look at a couple of examples: We now know exactly how much air we will use for every minute we spend at a certain depth. Respiratory Minute Volume (RMV)Ĥ0m 5 Bar x 25 LPM = 125 LPM Bottom Phase of the Dive If a diver rushes to the surface with full lung capacity at 20m the lungs would expand a further three times normal with the largest pressure change of all happening at the last ten metres when it would double. An ascent to the surface without exhaling would cause the air already in the lungs to expand further, but with minimal capacity to do so. But when breathing compressed gases, as in scuba diving, the mass of gas in the lungs is increased to fill the normal volume. When a diver surfaces or ascends these figures are reversed. At 20m it is one third, at 30m it is 1/4, at 40m it is 1/5. Therefore total lung volume during a breath hold dive at ten meters is half of what it was at the surface. Boyles Lawīoyle's Law states "For a fixed amount of an ideal gas, kept at a fixed temperature, pressure and volume are inversely proportional."įor every ten meters of descent the pressure increases by one atmosphere absolute (ata or atm). We call this the Respiratory Minute Volume (RMV) and it is also measured in litres per minute(LPM). We can use our SAC rate and Boyle’s law to work out how much air we will breathe at any given depth. use previous logged dives to calculate your SAC rate OR if your computer is downloadable to a supplier piece of software, download and use the application, which in most instances will calculate and show you, your SAC rate. If you do not know your SAC rate, then assume a value of 25 litres per minute, but do not rely on this figure. Your SAC rate is how much air you breath during 1 minute while on the surface, usually while doing gently finning. The next figure you need is your Surface Air Consumption (SAC) rate. To calculate the amount of air in a cylinder you multiply your cylinder size (litres) by the cylinder pressure (Bar).Ĭylinder size x Fill pressure = Available Airġ2L twinset x 210 Bar = 5,040 Litres How long will that last me during the dive? Do I have enough reserve air for my buddy?.How long will that last me during the dive?.Its the answer to the following questions. Remember your maximum dive time will vary with cylinder size and dive depth. Do you just go diving and assume you have enough air for the dive or do you take a minute and plan. Air planning is a key factor when it comes to planning a dive. Fonelab for Android Data Recovery is a great solution to the constant threat of data loss that is so prevalent among mobile users today.

I was going to install it in my '63 then decided to keep it as delivered from the factory. I have a couple of the package shelfs with the perforations as well as the rear seat speaker mounting hardware and harness that plugs into the main loom that goes into the trunk. The substructure under the package shelf was set up to allow for installation of the speaker, which is mounted on a stamped sheet metal plate that bolts to the body substructure under the shelf. Package shelfs that were perforated for a rear seat speaker were used with the speaker opening offset to the side (I forget whether it was passenger or driver, think it was passenger). I say he is dead wrong.Ī factory-installed rear seat speaker option was available for '63 closed cars. And he says the radios did not have a Fader, I am trying to create this feature. My opposition says the '63s did not have a rear seat speaker, could not "carry" a 2nd speaker and adding one would ruin the radio and that I have done so by adding a rear speaker (I didn't add it, it was already there with my AM radio). This Fader control was the large knob on the right side of these radios, behind the smaller Station Selection knob. (I've owned three '63s and all three had a factory made pre-punched rear window shelves.) And the AM and particularly the AM/FM radios came with a Fader, to enable "balancing" the front to rear seat speaker output (volume level of the front versus rear speaker). This pre-fabricated location for the rear speaker was not centered, but offset to the passenger side. I say 1963 T-Birds came with a factory pre-punched rear deck shelf (aka, package shelf) to accommodate a rear radio speaker. Can anyone confirm for me - I have an intense debate going. Monica claimed that one day the previous fall, she found her pigs in a feeding frenzy.

It appeared to me to be a human leg that had been severed mid-femur, down to the toes,” Denney said.ĭetectives brought Monica into the sheriff’s station for questioning. “It was clear that it was not an animal bone. Then, investigators spotted something truly disturbing: a human leg in a catchment pond.

Officers were taken aback by the squalor, which included piles of garbage, rotting food, and industrial waste. Law enforcement officers executed a search warrant on Monica’s property. “I was really concerned that there was some foul play involved.” “That’s when I was like, ‘OK, we got something else going on here,'" Henderson said. “It had been used at a date after Susan Monica said that he had disappeared,” Jackson County Deputy District Attorney Allan Smith told producers.ĭetectives then reviewed security camera footage - which showed Monica using Robert’s EBT card.

Monica claimed Robert then began drinking heavily and acting erratically. “He received a concerning phone call from a family member that she had been the victim of assault and he was really upset about that,” she had said, Henderson told producers. Monica told them Robert had lived and worked on her property for six months but took a bad turn in the fall. “I’m thinking to myself as we’re pulling up, ‘Are we in The Twilight Zone here?’" Henderson recalled. The property was cluttered with vehicles, debris and makeshift structures. They learned months had passed since anyone had seen Robert and he had lived on cash, all of which made it difficult to track his movements.ĭetectives drove out to Monica’s property to ask her about Robert’s disappearance. The Haneys filed a missing persons report with the Jackson County Sheriff’s Office. said “It made the hairs on the back of my neck stand up.” His dog was still running around and all his tools were there,” Jesse. She wanted us to come retrieve our dad’s stuff,” Jesse told producers.īut when they saw his trailer, the Haneys knew something was wrong. “Susan Monica said that my dad just basically left. They spoke to Monica, who claimed she hadn't seen him since he quit four months earlier. 1, 2014, the Haney kids drove out to check on their dad. We just all started to panic,” Jesse told producers. “We hadn’t seen or heard from my dad for two months. However, things got a little too quiet in December 2013. Jesse said his father enjoyed the peace and quiet of living alone out in the woods. My dad agreed to build a house from the bottom up,” son Jesse Haney explained to producers. My dad would get part cash and be able to stay on the property. Robert had found Monica through an ad on Craigslist. Whatever she asked of him, he did,” former employee Sean Leimanis told “Snapped.” “He was her handyman, laborer, carpenter. She erected a large barn and started work on a house. When Monica first bought her property, it was undeveloped woodlands. She had a herd of pigs, raised chickens, and ran a wrought-iron fence and gate-building business named White Queen Construction. In 1991, Monica bought a 20-acre farm in rural Wimer, Oregon. “She got into an engineering career and was very successful,” former Jackson County Sheriff’s Detective Eric Henderson told “Snapped,” airing Sundays at 6/5c on Oxygen. Following an honorable discharge, she began living as a woman. Monica was born Steven Buchanan in California in 1948.

(2012) indicated that whilst not used in a high number of cases, those workers who co-created a handwritten genogram with a family (in contrast to the worker completing the system genogram) would include more extensive wider family members. I would take either a big sheet of paper or lots of pieces I could later join together, some coloured pens and draw a genogram and key, focused on the unique dynamics of the family.Ī study by Laird et al. I quickly fell in love with the concept – more than just asking and drawing who was in the family, but exploring the relationships, family scripts and social GGRRAAACCEEESSS within the family network. Prior to this, I had used the genogram/family tree function on the local authorities recording system, but other than using and adding to this to understand who (to our knowledge) was in the biological family, I had not used it as a tool for direct or relational work with families.Ī genogram is a visual tool that shows a family tree and is used to give a pictorial representation of a family system. Author: Hannah Scott When I was two years into my social work practice, I was introduced to the cultural genogram through systemic training. Diagnosed with psychotic melancholia, he died of pneumonia two years later at the age of 46, without recovering from his mental illness.īiography Early life Schumann's birth house, now the Robert Schumann House, after an anonymous colourized lithograph After a suicide attempt in 1854, Schumann was admitted at his own request to a mental asylum in Endenich (now in Bonn). What is now thought to have been a combination of bipolar disorder and perhaps mercury poisoning led to "manic" and "depressive" periods in Schumann's compositional productivity. Schumann suffered from a mental disorder that first manifested in 1833 as a severe melancholic depressive episode-which recurred several times alternating with phases of "exaltation" and increasingly also delusional ideas of being poisoned or threatened with metallic items. These characters bled into his editorial writing in the Neue Zeitschrift für Musik (New Journal for Music), a Leipzig-based publication that he co-founded. Schumann was known for infusing his music with characters through motifs, as well as references to works of literature. His best-known works include Carnaval, Symphonic Studies, Kinderszenen, Kreisleriana, and the Fantasie in C. He composed four symphonies, one opera, and other orchestral, choral, and chamber works. Later, he composed piano and orchestral works, and many Lieder (songs for voice and piano). Until 1840, Schumann wrote exclusively for the piano. Clara and Robert also developed a close relationship with German composer Johannes Brahms. A lifelong partnership in music began, as Clara herself was an established pianist and music prodigy. In 1840, Schumann married Friedrich Wieck's daughter Clara Wieck, after a long and acrimonious legal battle with Friedrich, who opposed the marriage. Schumann then focused his musical energies on composing. His teacher, Friedrich Wieck, a German pianist, had assured him that he could become the finest pianist in Europe, but a hand injury ended this dream. Schumann left the study of law, intending to pursue a career as a virtuoso pianist. He is widely regarded as one of the greatest composers of the Romantic era. Robert Schumann ( German: 8 June 1810 – 29 July 1856) was a German composer, pianist, and influential music critic. Whether he had died or still lingered in the dungeons of Austria was not known.
