Research Note 112: Procedures

Dr. Wood wants me to write down a day of mine and send it for reference, so I'm gonna do it my way, and edit it later. "Explain it like I'm an intern following you." Sure thing doc.

*QUE UP MR. BLUESKY BY ELO on the playlist*

Wakeup with 10 minutes till I have to leave. Rush out to car, hop in and drive to the clinic. I usually make it with 20 minutes to spare. Morning meeting, with about half of us in treatment its definitely getting diverse, haha! Everyone talks about any updates with equipment, goes over a patient list and needs, and then shares how their treatment is going for research purposes. It also helps us provide better patient experience.

I then go over to the patient intake rooms and talk with the nurses who help prescribe the gene therapy part of the treatment. I ensure they know where we plan to do beam work on each patient so they can help prep them and answer any questions. Less of a surprise really helps. Sometimes, the bioengineers are around, and I pick their brains on how they make up the different species and treatments. It's incredible how much they can do with a pill.

We usually get our first patients at 10. They go through the waiting room and get called back to an intake room to speak with the nurses first. The usual vitals and weight are taken (if the patient can fit on the scale), and they go through a long questionnaire to see how they've felt, changes they've noticed, and concerns they have. If they are a returning patient, they'll usually get a physical on areas we have treated, a blood panel, and nurses will search for any malformities in their changes. Doctors, mainly geneticists, will come in after, and prescribe their next course of medication (that has to be synthesized at our lab; they'll update any changes and work on filling while the rest of the treatment is happening.)

I'm not always patient-facing, but when I can be, (I love helping with this part), I fill in often. I'll get called to come and escort the patient to a diagnostics room. This lab has every scanner, x-ray, and probe imaginable. Patients are put on this table that is built like a shoe sizer, which spreads them into a t-pose. The diagnostics are operated by a radiologist while a geneticist overwatches the scans. Most patients fall asleep in the half-ish hour this takes. Between the computer and their decisions, new treatment areas are chosen. If need be, a nuclear operator (like me!) can fill in for the radiologist, as the diagnostics are effectively the same as in the proton beam machine.

It's important to remind the reader, the beam therapy not only eliminates any malformed cells or abnormal changes, but helps break down areas that are stubborn for the new species cells to fill. Think of it as blowing microscopic holes that the animal goop fills, then spreads around.

*Que "Dyson Sphere" by Epic Mountain music (kurzgesagt) on the playlist*

We'll then pull the patient out of diagnostics, and let them have a few minutes to stretch and relax before they are taken down a winding concrete hallway into the treatment room. Then, they get laid back down on a table similar to the one before in a dark room with a glow around the table and beam arm. Have you ever played Portal? The arm looks like GLaDOS, but with a narrowing probe down to the end. This time, the patient is restrained lightly by thin bands about every 10 inches. They cannot move while the beam is firing, or it might get healthy tissue! The technician then leaves the room back through the winding corridor and works from a station remotely. There has to be so much separation and concrete so someone doesn't accidentally get blasted by protons. The computer will then retrace where the geneticists and other computers highlighted, firing beams like lines in a tattoo. The real sci-fi part of this treatment is how the beam selects depth, and how fast it can track and find new targets. This technology was originally experimented with to help break down radiation-damaged cells, and then cancer, but it also works very well on removing the cancer that is humanity. (<-Joke, kinda) Even more than that, we've discovered ways to augment treatments for, well, everything. My favorite is using [REDACTED] to create cosmic rays for cosmic beings. (We've been accused of creating gods, demons, and horrors with this, but that's for another note) For about 30 minutes again, the arm will whirr and buzz around the patient. Midsession, the beam will stop, and run a second scan to verify nothing is reacting poorly to being beamed out of existence. It then goes back to targeting and firing. Most patients fall asleep while it goes; I've felt a sunburn-like feeling where I've gotten my treatments, but it usually dissipates by the end of the day.

*Que "Science Fiction Double Feature" From the Rocky horror picture show on the playlist* I'll give them about 5 minutes unless they are antsy, then come in and release them. Usually help them stand up, catch their balance, and walk out. I keep lollypops at the door, and make sure everyone gets one. They then go back to intake to get one last look over before being sent on their way, with most returning in 3 months.

My regular job, now that we are out of development, is relatively simple. In between patients, I do a complete inspection of the patient-facing part of the machine, then go back into the equipment rooms and verify everything is still functioning. The particle accelerator needs 'fueled' every treatment. We also have to verify the cooling system is optimum. It is extremely risky for a patient to get incomplete treatment, so the system has to be perfect each time.

At the end of the day, (6ish) I'll check all the systems. I try to wipe down all the stainless every day to keep it nice (and scifi looking) and look over the days data for any anomalies we might need to fix the next day. I'll lock up the beam room, say bye to the second shift researchers and analysts, and leave, making it home by 8 and usually passing out after takeout. If it wasn't for the patients, it would be the most boring job. But, thanks to the real stories, it never is. There, a long-form, first day in the life of Ceri the kinda sorta dragon. -Ceri

Engine Repair Instruction Full Guide

Engines are the heart of any vehicle, powering everything from your daily commute to long road trips. Knowing how to repair an engine can be a game-changer, whether you're an enthusiast who loves getting your hands dirty or someone looking to save money on mechanic bills. This guide will walk you through the entire process of engine repair, from diagnosing problems to reassembling your engine and ensuring it runs smoothly.

Understanding the Basics of an Engine

Before diving into the repair process, it’s crucial to understand how an engine works. Most vehicles use an internal combustion engine, which combines fuel and air, ignites it, and transforms that explosion into mechanical energy.

Components of an Internal Combustion Engine

The main components include:

Cylinder Block: The engine's core where combustion occurs.

Cylinder Head: Houses the valves and spark plugs.

Pistons: Move up and down to create the force needed to turn the crankshaft.

Crankshaft: Converts the pistons' up-and-down movement into rotational motion.

Camshaft: Controls the opening and closing of the valves.

Valves: Regulate the flow of fuel and air into the engine and exhaust gases out.

How an Engine Works: A Simple Explanation

An engine works by pulling in a mixture of air and fuel, compressing it, igniting it with a spark (in gasoline engines), and then expelling the exhaust gases. This cycle—intake, compression, power, and exhaust—happens in each cylinder and repeats hundreds of times per minute.

Tools and Equipment Needed for Engine Repair

Whether you're performing a basic repair or diving into more complex work, having the right tools is essential.

Essential Tools for Basic Repairs

Socket Set: For removing and tightening bolts.

Wrenches: Different sizes for various engine parts.

Step-by-Step Guide to Reassembly

Prepare Your Workspace: Ensure that your workspace is clean, organized, and well-lit. Lay out all the parts and tools you'll need in the order of reassembly. Keep the engine manual handy for specific torque specs and sequences.

Install the Crankshaft: Place the crankshaft back into the engine block, ensuring it is seated correctly. Use assembly lube on the main bearings to prevent damage during the initial startup. Torque the main caps to the manufacturer's specifications.

Insert the Pistons: Install the pistons and connecting rods. Be sure to align the piston rings correctly and use a ring compressor to insert the pistons into the cylinder bore. Attach the connecting rods to the crankshaft and torque the rod bolts to spec.

Install the Camshaft and Timing Components: If your engine uses a timing chain or belt, install it according to the timing marks on the camshaft and crankshaft gears. This step is crucial for ensuring the engine's valves open and close at the correct times.

Attach the Cylinder Head: Place the cylinder head gasket on the engine block, followed by the cylinder head. Torque the head bolts in the correct sequence and to the proper specifications. This ensures a good seal and prevents head gasket failure.

Install Valves, Lifters, and Pushrods: If applicable, install the engine's valves, lifters, and pushrods. Make sure they are properly aligned and that the lifters are seated correctly in their bores.

Reassemble the Valve Train: Install the rocker arms and adjust the valve lash according to the engine manual. Proper valve lash is critical for engine performance and longevity.

Reattach External Components: Begin reattaching external components like the water pump, oil pump, timing cover, oil pan, and intake manifold. Replace any gaskets and seals during this process to prevent leaks.

Reconnect the Fuel and Ignition Systems: Reinstall the fuel injectors, spark plugs, and ignition wires. Ensure all electrical connections are secure and properly routed to avoid short circuits or malfunctions.

Final Checks: Before moving on, double-check all connections, bolts, and components. Make sure nothing is left loose or unconnected.

Applying Proper Torques and Specifications

Every engine has specific torque settings for each bolt. Over-tightening can strip threads or warp components, while under-tightening can lead to leaks or parts coming loose. Use a torque wrench and follow the manufacturer's specifications closely.
