WERE DOING SPECBIO STUFF AGAIN BABY. Feels fucking good to get back to my roots (i get to close 50 tabs worth of research now. Delightful)

Terminators are made of a Titanium Alloy (Im going with ferrotitanium which is a mix of iron and titanium. They never specify in the movie what the titanium is mixed with so fuck it we ball baby)) skeleton contains limited amounts of Mimetic Polyalloy (fake material used for the terminator in terminator two). Mimetic polyalloy can be hard or flexible and will be used to create new structures that the iron collected from food will later fully establish. This will allow his metal endoskeleton to mimic standard growth that a regular skeleton would have growing up.

When first introduced to the foster system (medical checkups are required once entering the foster system. The police probably do some checkups on Robbie also just to make sure hes okay when they find him), medical tests show that he has anemia, so it’s  recommended he be put on iron supplements. My reasoning is any iron in his blood is almost instantly sent to work on growing his endoskeleton. That means the actual amount of iron left in his blood is pretty low (the opposite of this is hemochromatosis which is when there's too much iron in your blood). I could see him probably trying to stop iron supplements but I think there would be some side effects to convince him to start taking them again. His joints might ache or I could see child terminator Robbie saying some mildly concerning shit like ‘my bones feel hungry’. I also think he might crave foods that are high in iron. Like beef/chicken liver, canned tuna, and seafood. Idk how frequently he could AFFORD these things but yk. The endoskeleton hungers eternal  ¯\_(ツ)_/¯

Nanobots are used to repair wiring for his nervous system, synthetic muscular system, acts as his immune system and sometimes accelerates healing for his organic systems (organic parts of his muscular system, skin, and nerves). For the most part his organic systems heal on their own at about the same pace as a normal human person. Nanomachines/nanoparticles are fueled by glucose (if Robbie needs work done by the nanobots he might need to eat or crave sugar both before and afterwards). 

He probably has a fairly (?) normal digestive system and circulatory system. The spread of his circulatory system is just more limited because some parts of him don't really need blood. . The primary job of the nanomachines when they aren't busy healing or growing his body is to harvest as much heme iron from the food/supplements he consumes as possible so that it can be repurposed later. His immune system is taken care of by the nanobots so all he has to worry about is red blood cell and plasma production. Similar to adults, most of this takes place in his spine, ribs, skull and breastbone. The red bone marrow is stored inside these metal parts and the red blood cells are then released into his bloodstream. Plasma is created in the liver and also in bone marrow so most of that stays the same

Another fun bit about the endoskeleton:

Bones close to his skin that are in danger of being exposed (knuckles, kneecaps, cheekbones) have a very thin enamel coating to preserve the illusion that they are bones. But underneath it’s all just the same Ferrotitanium.

onto the muscular system

Muscles are laced with a Shape Memory Alloy called Nitinol. A flexible (SURPRISINGLY durable godamn) metal material made of nickel and titanium that reacts to electrical and thermal impulses. It’s already used in the medical field (I can not fucking BELIVE that this is real thats so so so SO fucking cool). Superficial muscles are more organic (80% muscle 20% nitinol) but as the muscles go deeper they become more and more synthetic (20% muscle 40% nitinol 40% titanium wiring for durability). Superficial muscles are more muscle for stealth purposes. If injuries go deeper than anticipated he will still be able to fly mostly under the radar, assuming no wires have been significantly dislodged. If he’s been injured into the deeper layers then there’s no use in trying to lay low anymore. He’s clearly in a combat situation and stealth protocols no longer matter.

ALSO I did some math to try and figure out how heavy Robbie would be with all this metal in his system. Heres the logic for my equation:

CONTENT WARNING. MATH.

About 12 - 15% of your body mass is bone. A person weighing 155 lbs will have about 22lbs of bones. One Cubic centimeter of bones will weigh about 1.85 grams.

Ferrotitanium alloy is 4.5 grams per cubic centimeter. 

The equation 1.85/4.5 = 22/x in which x is his new bodyweight. Multiply 1.85 by 2.43 to get 4.5. Because the equation must be symmetrical you then multiply 22 by 2.43 to get 53.5 lbs.

With all of the extra metal in his system, I think it would be reasonable to assume that he LOOKS like he should be about 155 lbs but his actual weight is around 250 lbs. I have. NO idea how doctors are going to deal with this.

Had some VERY FUN hypotheticals from @moosemonstrous (thank you for proofreading my insanity once again <3) about his body shedding as much water as possible and like. shriveling his organs to drop as much weight as possible before doctors appointments. But given that he is a cyborg and not an android I do think that might kill him so Im thinking??? Maybe people just assume the scale is broken.... every single time he's in.

IDK man if they have access to his wack ass file then his breaking the conservation of mass is the least weird thing in there.

OKAY YAYYYYY NOW THAT I HAVE HIS INTERWORKINGS LAID OUT I CAN DO FUN CYBORG GORE!!!!! <33

[grapeagata]

Shout out to Nitinol for being cool as fuck. It's made of nickel which in it self is awesome and needed for the hmuan body to work properly so Thank you nickel. (Everybody say Thank you nickel).

It's structure is awe-some and super cool and it's got a monoclinic crystal structure which I don't know what that is but it sounds radical

It's ALSO ALSO super elastic BUT it's also a metal alloy so like, it's got everything and it's beautiful too and it's used in medical stuff too which is so good so like, if you're alive right now it might be because of nitinol, so Thank you nitinol, for keeping us alive and well! And also for being incredibel!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

So like, if you don't like Nitinol then never talk to me, (DNI Nitinol Haters!) If you DO like Nitinol then you can like talk to me and be friends with me and kiss me on the mouth or whatever, if you like Nitinol I love you, and since most people like nitinol (because how can you not) that means I love all of you, so Thank you Nitinol, for bringing people together.

Anyway go like, look up nitinol on whatever search engine you use because you deserve good things and no thing is better than Nitinol

Superelasticity and Shape Memory of Nitinol

Nitinol (Nitinol) alloys have many material and device characteristics, for example, kinking resistance, stress constancy, dynamic interference, deflection stiffness, magnetic resonance imaging (MR1) compatibility, radiopacity and biocompatibility. The most famous characteristics of Nitinol are its superelasticity and thermal shape memory. Although the term "shape memory" describes the phenomenon of restoring a predetermined shape by hearing and deforming the shape "plastically", the term "superelasticity" refers to the great elasticity of these alloys, which can be 10 times greater than the best stainless steel. Steel used in medicine today. Although both effects are spectacular, they are not the only important properties of the material.

Nitinol has two characteristics: shape memory effect (SME) and superelasticity (SE).

Shape memory Shape memory happens when mother phase of a certain shape is cooled from above the Af temperature to below the Mf temperature and completely forms the martensite, deforming the martensite below Mf temperature. After being heated to below Af temperature, with reverse phase transformation, the material will automatically restore its shape in mother phase. In fact, the shape memory effect is a thermally induced phase transition process of nitinol. It refers to ability of nitinol to deform at a certain temperature and then restore the original, non-deformed shape when the temperature is higher than its "transition temperature".

Superelasticity The so-called superelasticity refers to the phenomenon in which the sample produces a strain that is far greater than the elastic limit strain under the effect of external forces and the strain can automatically restore during unloading. In mother phase, due to the effect of external stress, the strain triggers martensitic phase transition so that the alloy exhibits mechanical behaviors that are different from those of ordinary materials. Its elastic limit is much larger than that of ordinary materials. And it no longer follows Hooke’s Law. Compared with shape memory effect, superelasticity does not involve heat.

The unique characteristics of these nickel-titanium alloys combined with strength, fatigue resistance, biocompatibility, and MRI compatibility provide an interesting solution for the design of advanced medical devices. Conventional metal materials used for stents, filters, and other interventional devices exhibit elastic deformation behaviors that are very different from those of human body structures. Nitinol alloys have similar behaviors. Nitinol is an aromatic or near-equiatomic intermetallic compound of titanium and nickel.

Top Five Things to Consider Before Undergoing Tavi Surgery in India

Are you or your loved one preparing for Transcatheter Aortic Valve Implantation or TAVI surgery in India? If yes, then before traveling to India for the procedure, there are a few crucial factors you should consider for a smooth journey. 

India is a hub of world-class medical treatments, such as TAVI surgery in Delhi. But before you pack your bag, understand the top five things you need to consider before undergoing TAVI surgery in India.

Choosing the Right Hospital and Surgeon

The quality of the medical staff and the hospital are key factors in a successful TAVI procedure. Look for hospitals with international accreditations, such as JCI and NABH. Some popular internationally accredited hospitals, such as Fortis Memorial Research Institute, Indraprastha Apollo Hospital, and Max Super Speciality Hospital, all offer advanced facilities with top cardiac specialists in India. 

Total Cost Involved in TAVI Surgery

One of the major reasons why international patients prefer India for TAVI surgery is the affordability. However, the cost may vary from place to place depending on various factors like the type of implant, treatment complexity, specialist fee, etc. The cost of TAVI surgery in top hospitals like Fortis Escorts Heart Institute is USD 27000 with American-made implants. 

Discussing cost details before traveling which help you budget better and avoid unexpected expenses. 

Type of Implant Used

During the TAVI or TAVR surgery, implants play a crucial role. The type of implant used for the procedure ensures long-term success. Various types of valves are available, including:

American Implants (brands like Edwards Lifesciences and Medtronic) 

European or Indian implants.

Make sure to discuss the pros and cons of each type with your medical team and choose the best option. 

Valve Used in the TAVI Procedure

In transcatheter aortic valve implantation or TAVI procedures, the replacement valve which is usually used is bioprosthetic which is made from animal tissue like bovine (cow) or porcine (pig) pericardium. Then, these tissue leaflets are mounted on a metal frame made of alloys like stainless steel or nitinol; it can be either balloon-expandable or self-expanding so that surgeons can facilitate deployment within the native aortic valve.

Planning Your Travel and Stay

Travelling to India for TAVI treatment needs a hustle free journey. From medical visa accommodation to food and transportation options, everything should be to the point. Also, patients need to stay 2 to 3 weeks until recovery and specialist approval. So, ensure you have a hospital or medical tourism facilitator's backup to fulfill these needs on time. 

Finally Thoughts! 

Undergoing TAVI surgery in India is a life-changing decision that combines high-quality medical care with affordability. By carefully planning and connecting with the best TAVI hospital in Delhi, surgeon, type of implant, costs, and travel arrangements, you can ensure a successful and stress-free experience.
