Polydopamine is the first adhesive polymer that can functionalize surfaces made of virtually all material chemistries. The material-independent surface modification properties of polydopamine allow the functionalization of various types of medical and energy devices. However, the mechanism of dopamine polymerization has not yet been clearly demonstrated. Covalent oxidative polymerization via 5,6-dihydroxyindole (DHI), which is similar to the mechanism for synthetic melanin synthesis, has been the clue. Here, it is reported that a physical, self-assembled trimer of (dopamine)2/DHI exists in polydopamine, which has been known to be formed only by covalent polymerization. It is also found that the trimeric complex is tightly entrapped within polydopamine and barely escapes from the polydopamine complex. The result explains the previously reported in vitro and in vivo biocompatibility. The study reveals a different perspective of polydopamine formation, where it forms in part by the self-assembly of dopamine and DHI, providing a new clue toward understanding the structures of catecholamines such as melanin.

In recent years, Janus materials have become a research hotspot in the field of materials science; however, fabricating inorganic Janus-like nanofibers (NFs) is still a challenge. Herein, we report novel ZnO/NiO Janus-like NFs with efficient photocatalytic performance via an electrospinning method followed by calcination treatment. The morphology, structure, chemical composition and crystallinity of ZnO/NiO Janus-like NFs were studied in detail via SEM, TEM, HRTEM, EDS, FT-IR, XPS and XRD, indicating that the NFs had a perfect Janus-like structure composed of ZnO and NiO.

Routine equipment maintenance was preformed including reverting to the original NGA capillary columns used on the unit because of inconsistent results. Parts were ordered for the ignition section of the atomic absorption unit. Support was given to the JANUS group, who reviewed the chemistry lab database applications. Worn areas on the lab bench top surface were renewed, and cabinets were cleaned, painted, and relabeled. Sandy Dillard was introduced to some of the lab equipment and procedures.
Two network hubs were replaced with wideband fiber optics based units during the initial underway time. The physically larger size of the units slowed the replacement. This upgrade caused problems with Appletalk zones using the FastPath interface to the ethernet system. The network maintenance jobs were done "after hours" to minimize interference with the JANUS group users.
Several computer viruses were discovered and cleared, primarily from SEDCO machines. SEDCO replaced eight of the PCs on their network.
The catwalk heaters were wired and installed above the catwalk area in preparation for the upcoming high-latitude cruises. The electrical department then removed the heaters for storage until they are needed.
No curatorial representative sailed on Leg 174B. Eight cores were collected, tagging basement. Interstitial water samples were taken for the chemistry lab and physical properties and cryogenic magnetometer measurements were made. The interstitial water samples were squeezed and analyzed. Three X-ray diffraction (XRD) samples were taken. The samples and cores will remain on board for shipment to the BCR with the Leg 175 collection.
Support in the labs was mostly routine, addressing problems with the pycnometer in the physical properties lab and the atomic absorption unit in the chemistry lab. A second EPC recorder was installed in the underway lab to replace the 12-kHz Raytheon machine. The 12-kHz transceiver and transducer were investigated as the system failed in deep water. Both copiers required maintenance and were cleaned.
An ongoing project to remove obsolete Totco and DCS sensors and wiring was outlined and initiated.
The cryogenic magnetometer was filled and tuned during the New York port call. A series of experiments with wash cores and a hybrid core barrel with a stainless steel section were conducted to identify possible sources of magnetic overprints on sediment cores. Initial results concluded that the core barrel was not the major contributor to the overprint.
The microscope lab was used primarily by JANUS members who used the computer facilities.
No core samples were processed. Electrical power distribution in the area was modified to dedicate a circuit to the dishwasher; the extension cords were removed.
Physical properties measurements on the eight cores included multisensor track runs, thermal conductivity, index properties, and shear strength. The pycnometer process controller caused some trouble but is presently working. Information and suggested spare parts were requested. The Tech Help for the lab was brought up to date.
Four of the staff volunteered for the METS team and mustered for two fire drills. The library safety video VCR was moved to SEDCO's lounge for their ongoing Quality Through Teamwork indoctrination classes. Two Safety/training wood shop videos, missing for several legs, have not been returned.
Whereas preparation for the port call was fairly hectic, administration of the plan went fairly well. Anticipated difficulty with the Unions proved to be unwarranted. As this was a cruise ship and passenger terminal, the layout was not optimal for normal dockside loading and unloading.
Sets of positions were collected on site to compare the data quality of the two types of GPS receivers, the Omnistar GPS and Ashtech GPS/GLONASS. The second EPC flatbed recorder was installed, replacing the 12-kHz Raytheon flat bed recorder. The Pelagos annotation software was tested with both recorders; a few problems remain. A replacement power supply for the 12-kHz transceiver is expected in the coming shipment.
The hydraulics system associated with the hose handlers was disassembled to replace valves. Hoses and associated fittings were also replaced. Seals in two hose puller motors failed at different times; one was replaced. Planned space modifications and furniture installation for the underway lab was deferred as the furniture was not shipped to New York City as anticipated.
A test seismic line was conducted on 7 August to work with the yellow multichannel array. Various preamplifier and gain values were used to match the analog record of the multichannel array with the single channel analog record. Various lead weight combinations and lengths of cable played out were tried on the multichannel array to achieve comparable depths with the single channel array at the same speed. Initial conclusions are that the real time analog record from a six channel (six phones) combined does not compare with a 60 phone single-channel array.
Once the X-ray fluorescence unit stabilized, a long series of standards were made for major and minor element analysis in preparation for upcoming legs. Familiarization and training began for Bob Olivas in the X-ray lab, focusing on the XRD. There was exposure to other X-ray lab routines and the JANUS data application that is being developed. Three XRD analyses were made of samples taken from Hole 1074A.

Johny, thanks for your reply
I also was wondering if I am allergic to Miracle-Mineral-Supplement as my chest looks like I have a bad sunburn or have been burned with a hot iron. Is it possible there might be something wrong with the chemical as I have noticed when mixing it with lemon juice, it smells bad, but it doesn't seem to turn yellow, only gray. And I wonder just how all these different dealers are making it pure and with the correct perecentage amounts in them.
Since this is really the only reaction I have gotten so far, I think I will take your advice and stop for the present time and then start over after a short break. Maybe with a different activator. Thanks again for your input.

Evidence-based research. Proven results. Our scientific approach makes a difference. In fact, it makes all the difference. With over 15 years of proven performance, growers know that when it comes to crop nutrition, they can always count on MicroEssentials® for the security of not just their livelihood, but their lives on and off the farm.
Growers know that micronutrients play an essential role in maximizing plant health and growth. With commodity blends, however, it can be difficult to ensure plants are getting the right balance of nutrients at the right time across their growth cycles for operations to actually see increased yields.
Through a groundbreaking design that utilizes phosphorus as the vehicle for the optimal delivery of the essential nutrients, MicroEssentials® solves the typical challenges with nutrient balance, uptake, and availability by fusing everything into a uniform granule, packed with crop nutrition innovations.
Now is the time to double down with MicroEssentials® and turn a good year into many great ones.Download our white paper on maximizing profits.
With so many factors that can impact the success of your growing year, it’s nice to know that when it comes to crop nutrition, MicroEssentials® phosphate-based fertilizer has you covered. With proven technologies like uniform nutrient distribution and season-long sulfur availability backed by over 12 years of performance data, you can spend less time stressing over the fruits of your labor, and more time enjoying them.
MicroEssentials is available in three distinct formulations, each catering to a unique lineup of crops and soil conditions.
To dig deeper into the crop nutrition behind MicroEssentials®, explore our full library of articles, research, and other resources.
Raising a productive crop depends greatly on the nutrients a plant is able to access during its life cycle. Many factors influence the availability of those nutrients, including soil pH. For instance, as soil pH increases, the availability of phosphorus (P), zinc (Zn) and iron (Fe) decreases. Although variety selection can help manage iron deficiency in soybeans, fertilizer application is still needed to address the P and Zn deficiencies prevalent in high-pH soils.
Evaluate the yield response of MicroEssentials® SZ®
Even with the increased focus on micronutrients and their importance to crop health and yields, basing a solid nutrient management plan on macronutrients is still critical. While macronutrients and micronutrients certainly work best together to create a balanced approach to crop nutrition, the key difference between them is the amount needed for proper plant growth.
Determine the rate of MicroEssentials® SZ® that can safely be placed with soybean seed in 7.5 inches and 30 inches row spacings.
Are you seed-placing your phosphorus (P) and basing application rates on seed safety rather than crop requirements? You may be leaving yield on the table. Recent research out of the University of Manitoba examining seed-safe rates of P and sulfur (S) in canola is showing that P applied at rates based on seed safety may not be adequate to maximize canola yields.
Quantify the effect of a comprehensive fertility program including MicroEssentials® SZ® (12-40-0-10S-1Zn) + Aspire® (0-0-58-0.5B) compared to a conventional fertility program of MAP (11-52-0) + MOP (0-0-60) or MAP Only in a four-year cropping system.


Legal steroids is a term recently developed to refer to legal steroids online or legal steroids that work alternativesto illegal ones.If online and illegal are interchangeable terms, then legal steroids would refer to something from the internet, steroids legal in qatar.Legal steroids on the other hand refers to things that use a chemical ingredient, steroids legal greece. It is sometimes used to describe a substance that is used as an alternative to a prohibited substance such as cocaine or heroin, steroids legal in south korea.This does not mean that only legal steroids are used online, but it does mean that this kind of steroid would be used on the internet.Legal SupplementsThe term legal supplements can also refer to different type of supplements on the market today, steroids legal in england. These two terms are interchangeable.However, legal supplements do not mean substances that are produced, manufactured or prepared as a legal supplement, steroids legal in south korea.These examples include steroids, amino acids, vitamins, minerals, water, herbal medicine, vitamins and herbs.In terms of the two terms, the first legal supplement would be illegal substances, while the second would be legal supplements.The difference comes from which ingredient is produced, manufactured and prepared, steroids legal in qatar.There is no legal product, but there is a legal supplement. Legal products can be created using chemicals, but illegal substances can only be prepared using the substances they contain, greece steroids legal.This might be a reference to an amino acid or a salt. If the substance contains both chemicals and salts, then the legality of the supplements is identical to that of the substances they contain, steroids legal japan.This means that these legal supplements could include:Fractionated fish oilBeta caroteneCitrus flower extractCoconut oil, palm kernel oil, canola oil, sunflower oil, olive oil, sesame oil, soybean oil;Natto oil; andSoy protein (sometimes called whey protein), soy meal, natto powder, sesame protein, soy protein.Although a product might contain all these ingredients, some brands also might refer to these products as legal supplements. They might not contain all of them as is the case for all legal products.Legal supplements are manufactured and prepared by a manufacturer with strict health and safety regulations, for example, these products are tested before they arrive on markets.The legal supplement manufacturer is responsible for ensuring its products are safe for consumers, steroids legal greece2.The difference between legal and illegal supplements can be seen based on specific components used by the manufacturer of the supplements, steroids legal greece3.
Decaduro The basic working of DecaDuro is to put the human body in a state called anabolic stateto make testosterone and anandro-injectable hormones, which have the ability to produce growth (and strength), and to inhibit the activity of thyroid hormone so it can act like a hormone-regulating hormone system for the body (that helps protect the organs from damage from exercise and can also promote healing of muscle tissue). It is also used to stimulate the muscles during workouts, and to get the metabolism back up to where it had been at the beginning of a workout. Anabolic steroids are considered the most powerful and reliable (although some believe they're also a form of abuse), deca durabolin 50 price. They cause the body to produce more testosterone, an increase in the growth hormone/prostate-derived and liposomal testosterone synthesis, and the muscle-building effect. Anabolic steroids can also interfere with metabolism, decaduro boline. Since the body does not have natural testosterone production receptors (that are located near the testes), they are capable of causing damage to muscle tissue even in the presence of testosterone levels below those needed to produce the proper levels (known as "antiepileptic" effects), deca-durabolin uses. Since they also interfere with the liver, and thus are known as "liver-destroying" steroids, these steroids can also slow the rate of fat loss. They also cause acne, increased libido, increased cholesterol, and possibly increase the risk of breast cancer. Many of the more common prescription drugs, such as beta blockers and anti-convulsants, may be used as anabolic steroids, by accident, to increase muscle mass, deca durabolin bodybuilding. However, there is still a very limited amount of information available about the use of steroids as a treatment for obesity, steroids legal in qatar. This is because the vast majority of the available research is done only on dogs (as they have better memories than humans) and is very anecdotal. What is known is that they are often used to treat both diabetes and obesity, and their use for this purpose is growing, decaduro boline. It's a very important therapeutic medication and will be very helpful in many peoples' lives. There are some other drugs that are also used to increase appetite and energy levels. They work on the same receptors as the other steroids, but may be a different function altogether and they may have different toxicities, so keep this in mind, deca durabolin 50 price. The only one I can really name on an "official" scale (without any bias) is praziquantel. This is used by weight-loss surgeons to produce the appetite increase that they hope to see with the drugs.
Many of the side effects of Tren are similar to other steroids, but Tren also carries some possible side effects that most steroids do notcarry. Many of the possible side effects that occur with Tren can occur with any steroid if you use it daily.For example, steroids can cause muscle loss, and Tren can accelerate muscle loss. If you use Tren to gain muscles, you are more likely to lose these. So you need to watch these possible side effects closely. Tren also contains the same amount of a substance called nandrolone which has been found to cause infertility and kidney stones in some people. These side effects were not known until the drug first came on the market.Many of the side effects of Tren are likely to be related to the fact that it is a hormone. Tren is known to cause hormonal side effects. In addition, Tren can also have the same side effects as some other drugs, such as Adderall, a stimulant amphetamine drug. So when you take Tren to lose weight, you could also suffer from Adderall-induced headaches and memory problems.With Tren, you will need to watch closely how you use the drug and how many times per day you use it. These side effects may go away with more frequent use of the drug. In comparison to Tren, Adderall is probably less dangerous to users since it only affects certain parts of your body.Side effectsIt is quite rare for any steroids to cause major damage or even kill people. Even more rare than that is for Tren to cause major damage or even kill people. But you must watch your Tren usage carefully. You can easily get an unexpected side effect if you over-use or misuse Tren. This is one reason why it is important to watch your Tren use carefully.Tren can cause liver damage. This can cause liver failure, death, and problems such as irregular heartbeat, kidney failure, and blood clots. There is no known way to reverse liver damage from Tren, or even reverse Tren's effect on your liver. This is why you need to avoid drinking alcohol while using Tren.Tren is also known to cause an increase in your risk for prostate cancer, especially if you smoke. Therefore, if you are a smoker, consider avoiding Tren if you can.Tren can cause weight loss. Tren is usually better at helping people stay under a certain weight as part of an effort at losing weight without dieting. With regular use of Tren, your weight will decrease.TEuropol and greek investigators examining seized drugs.

Powder coating is a type of paint that is applied as a dry powder, as opposed to conventional liquid paint, which is delivered through an evaporating solvent. This type of paint is applied electrostatically and cured by ultraviolet light or heat. The benefits of powder coating are many and the process is a cost-effective alternative to liquid paint. Read on to learn more about this method and how it can help your business. Here are just a few reasons why you should choose this type of paint for your business.
Powder coats are not as expensive as paints. The main difference between them is that the powder is made as a liquid, which is then hardened and ground into a fine powder. The powder is comprised of millions of tiny particles of plastic. You can mix blue and red powder and expect the colors to be the same. This makes it an ideal choice for many applications. But when choosing a powder coating company, make sure that you choose a company that stands behind their product.
Powder coating is a great choice for commercial applications, because it's durable and can be applied to many non-metallic surfaces. It's also an effective choice for interiors, because it's scratch resistant and can make your interior look even better. A powder coat can be a durable and aesthetically pleasing option. Just be sure to keep the environment in mind when choosing a powder coating material. It may not be the best option for a small workshop or garage, but it can be used in a variety of projects.


The thermal conductivity of the beryllium copper material is conducive to controlling the temperature of the plastic processing mold, making it easier to control the molding cycle, while ensuring the uniformity of the mold wall temperature.
If the forming cycle of beryllium copper is much smaller than that of the steel mold, the average temperature of the mold can be reduced by about 20%. When the difference between the average release temperature and the average wall temperature of the mold is small (for example). Using beryllium copper mold material can shorten the cooling time by 40%.
The mold cost budget and the continuity of production are very important to the manufacturer. Under the condition that the strength and hardness of beryllium copper meet the requirements, the insensitivity of beryllium copper to the mold temperature stress can greatly increase the service life of the mold.
Before determining the beryllium copper mold material, the bending of beryllium copper should also be considered. Use strength, elastic modulus, thermal conductivity and temperature expansion coefficient. The thermal stress resistance of beryllium copper is significantly stronger than that of die steel.


A water stable Eu(iii)–organic framework as a recyclable multi-responsive luminescent sensor for efficient detection of p-aminophenol in simulated urine, and MnVII and CrVI anions in aqueous solutions†
A novel 3D Eu(III) metal–organic framework (Eu-MOF-1) formulated as [Eu(L)(H2O)(DMA)] (L = 2-(2-nitro-4-carboxylphenyl)terephthalic acid) has been successfully synthesized under solvothermal conditions and characterized by structural analyses. Eu-MOF-1 displays a new 3D framework containing EuIII ions, ligand L, and coordinated DMA molecules and water molecules. The fluorescence investigations indicate that Eu-MOF-1 emits bright red luminescence, and shows relatively high water stability and outstanding chemical stability under a relatively wide range of pH conditions. It is noteworthy that Eu-MOF-1 can quantitatively detect p-aminophenol (PAP) which is a metabolite of phenylamine in human urine. More significantly, Eu-MOF-1 is the first reported multi-responsive luminescent sensor for detecting the biomarker PAP, and MnVII and CrVI anions with high selectivity, sensitivity, recyclability and relatively low detection limits in aqueous solutions. Furthermore, the possible sensing mechanisms of Eu-MOF-1 for selective sensing have also been explored in detail. Eu-MOF-1 could be an ideal candidate as a multi-responsive luminescent sensor in biological and environmental areas.

You may be thinking that you’ve heard a lot about this CBD stuff lately. That’s probably because you have!
CBD, or its full name, Cannabidiol, has set the world ablaze over the last few years, popping up everywhere from television ads, corner stores, marijuana dispensaries to pet stores. It’s even invaded our food and cocktails as creative chefs look for ways to incorporate it into our diets.
But like many people, you might also be thinking, just what is this trendy new three-letter word that everyone seems to be talking about, and why am I just hearing about it now?
If so, you are not alone. While CBD has seemingly infiltrated our culture, there’s still much confusion about what it is and why it’s all of a sudden so widespread.
Let’s have a closer look…
What is CBD?
CBD, or Cannabidiol, is a chemical compound (called a cannabinoid) that naturally occurs in the cannabis plant.
There are over one hundred cannabinoids in a marijuana plant, but few have been studied to the extent of CBD and THC.
You may have heard of THC (tetrahydrocannabinol), the oft-referenced chemical that is responsible for creating the “high” sensation that marijuana users know and love.
CBD does not contain the same psychoactive ingredients as THC; therefore, it does not produce a noticeable “stoned” or “buzzed” feeling.
Some people report feelings of deep relaxation with CBD, while others feel nothing at all. While not known for its party-vibe qualities like THC, CBD is thought to contain a host of other medicinal benefits that has both scientists and consumers excited.
CBD is consumed the same way as THC, including inhalation, oils, or edibles like Sunday Scaries CBD Gummies.
How is CBD Different from Marijuana?
CBD is a non-psychoactive compound found in the cannabis plant – both marijuana and hemp variants of cannabis. However, any given cannabis plant can contain THC and CBD, just THC, or just CBD, depending on the strain.
With the booming marijuana industry, growers and producers offer a bevy of products designed to suit individual consumer’s needs.
Many people enjoy the benefits of CBD but have no desire to feel high, so they can procure their products in a bespoke fashion.
For example, hemp based CBD products are most popular with consumers who want the therapeutic benefits of cannabis, but without the high.
Why is CBD Suddenly so Popular?
CBD is flourishing right now, thanks to the widespread legalization of the plant. In 2018, the United States passed the Farmer’s Bill to legalize CBD derived from the hemp plant, making it legal to consume across the nation.
The widespread availability and the subsequent hype of health benefits have consumers intrigued and eager to learn more about this chemical compound that has been touted as a new wonder drug.
How Does CBD Work?
Our bodies have something called the endocannabinoid system, which contains neurotransmitters that attach to receptors in our nervous system and help synchronize an array of important functions like sleep, stress, appetite, and anxiety.
Though there is much to be learned about how CBD works with the body, scientists believe that the compound interacts with receptors in the endocannabinoid system and influences them in a way that produces the health benefits associated with CBD.
How is CBD Used?
CBD is most often inhaled by smoking or vaporizing. It can also be administered through ingestion in the way of chocolate, candy, and baked goods (edibles), topicals such as lotions and creams, and oils that can be applied under the tongue or mixed into a drink.
There is currently no consensus on dosage, so it is best to speak with a practitioner to determine where to start and adjust from there. The Food and Drug Administration does not currently regulate CBD.
What are the Health Benefits of CBD?
The main reason CBD has exploded onto the scene is due to its potential and perceived health benefits. Although research and studies are still in early development, the outlook is promising.
There are claims of benefits for a variety of ailments, both physical and mental, including:
- Cancer-related pain
- Skin issues
- Post Traumatic Stress Disorder
Medical studies are still in their infancy, but some of the findings have been encouraging.
A 2015 review suggests that CBD had a positive effect on people with certain anxiety disorders.
Another study in 2020 explored adding CBD to chemotherapy treatment as a way to boost the immune system during cancer treatment.
A 2018 study on mice reported benefits controlling inflammation for pain relief.
Are There Any Health Risks with CBD?
Although the consensus is that CBD is generally safe, most CBD products are not FDA approved and therefore have not been through enough testing.
There are some reports that CBD may not interact well with certain medications and supplements, so it’s important to consult with a doctor before consuming the compound.
Some reported side effects include:
- Mood changes and irritability
- Adverse reactions with alcohol or drugs
- Loss of appetite
- Dry mouth
As research and studies continue to ramp up, we will continue to learn more about this mysterious yet promising chemical compound. As of now, there simply isn’t enough data to hail CBD as a panacea to all of our ailments.
However, there is substantial backing in the medical field and an army of staunch proponents that currently swear by its healing properties. For now, it’s a wait-and-see situation as we are just scratching the surface on what CBD offers concerning health benefits.
There is no doubt that CBD is trending in an upwards trajectory as people look for more natural alternatives to alleviate unpleasant medical symptoms.
For now, if you are interested in experimenting with CBD, it’s best to speak with a medical professional to come up with a plan that is best for your situation.

I completed a lab to find the determination of Kc. I have to find the concentrations of reactants at equilibrium using an ICE table. The equation that were are using is
Fe^3+(aq) + SCN^-(aq) -> Fe(SCN)^2+(aq)
I have to create 5 ICE tables because we used 5 different test tubes each with a different concentration of SCN. The values I already have so far are the initial concentrations of reactants and the concentration of products at equilibrium.
For the first table the initial value of Fe is 1.0M and SCN is 1.0M. The concentration of product at equilibrium is 5.7 X 1o^-5M.
I set up the first ICE table like this:
Equation: Fe^3+ SCN^- Fe(SCN)^2+
I 1.0M 1.0M 0
C -5.7e-5M -5.7e^-5 +5.7e^-5
E 0.99M 0.99M 5.7e^-5
So for the concentrations of reactants at equilibrium, Fe is 0.99M and SCN is 0.99M
Did I do this correctly?

Parabens are synthetic chemical preservatives, commonly used in beauty products like shampoo, lotion, and deodorants. Parabens can accumulate in your body, and have been linked to hormonal disruption and reproductive problems. In studies of breast cancer patients, parabens have been found in the tissue of cancerous tumors–yikes! If you want to avoid Parabens in your beauty products, keep an eye out for methylparaben, propylparaben, butylparaben, and ethylparaben in the ingredients list.
Phthalates are found in toys, electronics, personal care products, plastic wraps, containers, and more. These petroleum based chemicals help soften plastics, and bind fragrances to perfumes, deodorants, creams, and other personal care products. Phthalates are are not chemically bound, meaning they can easily get released into the air, water, or your body, just by using the products as intended. Phthalates have been found to disrupt the endocrine system, which can cause reproductive damage, hormonal imbalances, infertility, mood changes, metabolism changes, and more.

IV set and drop infusion rate?
So my question is not about the math part but the fundamentals,
so I have this vitamin c medication that I need to deliver at a 1 gram per minute,
1) do IV sets have a volume control on them to set how many ml per minute to flow from the tube?
2) if I have an IV set with this description 20 drops/mL, I don t even know what exactly that is refering to, it take 20 drops for one milliliter to be extracted?? so what about the timing?
3)let s say your whole sterile pouch including Vitaminc C(75g=150cc) and MgCL2(2CC) is 750CC, and you are using a set that says on it 20drops/ml, what should you do to deliver 1 grams of Vitamin C per minute to the patient?
thanks a lot got it
1)it's a work of an eye and a timer
even after you plug it to the arm it will go down with the same rate?
2)I know for an IV we need a Container, IV set, and Catheter
there is another component idk what it's called, extension
from what I red on post number 2 here it's not recommended , specially for single infusions

1) Yes, there is a control on IV set but it is not called " volume control" ....LOL !!
It is an adjustable "clamp" that basically lets you squeeze the IV tubing to control the flow of medication through the bag. The clamp is adjusted to let you control number of drops falling through the drip chamber. For that particular IV set few drops of medication contains approximately 1 mL of medication. That drops are mentioned on the set. A macro set can specify about 5 or 0 or 15 drops for 1 mL, while a micro set can be almost 45 or 60 drops for 1 mL .
2) If you have a IV set with 20 drops/mL, then it means to deliver 1mL of medication you will need to set 20 drops. Timing is recommended by the doctor. Lets say the patient is required to have 1 mL in 1 minute then you will have to set 20 drops in 1 minute ( or 1 drop per 3 seconds). However, if you are requested to give 6 mL in 1 minute then you need to set 20x6 = 120 drops in 1 minute ( or 2 drops per second)
3) First find out how much mL of Vitamin C you need to give
75g = 150cc
then 1g = 150/75 = 2 cc or 2mL
Now the set mentions 20 drops/mL, so for 2mL we will need to give 20x2 = 40 drops
The timing requested is 1 minute, so you need to adjust 40 drops in 1 minute.
Now you will not wait for 1 minute to count 40 drops, so you find simpler ratio.
40 drops in 60 s means 2 drops in 3 sec. Just to be more accurate, maybe you will wait for say 9 s and check if you get 6 drops.
I hope this helps you understand the concept.

2. < 20 drops for one milliliter to be extracted > Exactly. So if you had to administer 1 mL/min, the drip rate is 20 drops / min.
3. 75 g / 150 cc * 1 cc/mL = 0.5 g/mL. Since the desired rate is 1 g / min you need to administer (1 g/min) / (0.5 g/mL) = 2 mL/min. At 20 drops/mL, you want to flow 2 ml/min * 20 drops/mL = 40 drops/min
