Chlorinated Solvents vs Petroleum Hydrocarbons

There are two classes of Volatile Organic Chemicals or VOCs. The first is Chlorinated Solvents and the other is Petroleum Hydrocarbons. Chlorinated Solvents are a family of chemical compounds created with chlorine, that are used in for such purposes as, degreasers, paint thinners, pesticides and more. Petroleum Hydrocarbons or PHCs is the name of a family of chemicals that are made from oil or products refined from oil, such as, gasoline, jet fuel, and diesel. The size of the molecules can also determine the value of oil. The smaller the size the more valuable the chemical.
Chlorinated Solvents vs Petroleum Hydrocarbons
A few examples of Chlorinated Solvents are, carbon tetrachloride, methylene chloride, and trichloroethylene. The chlorine in the compound helps break down organic materials such as, fats, which make it a useful cleaner. You can be exposed to this compound by inhalation or contact with your skin. Although it is easy to be exposed to these compounds, it is easy to leave the body by exhalation or urination.
A few examples of Petroleum Hydrocarbons are, polycyclic aromatic hydrocarbons or PAHs, benzene, and toluene. Most Petroleum Hydrocarbons are considered toxicological hazards. Chemicals are grouped together by their health guidelines. The measurement methods of them vary between countries but the easiest way for you to estimate the values of these chemicals is called total petroleum hydrocarbons or TPHs. The only issue with using this method is that you will not be able to estimate toxicity.
Petroleum Hydrocarbons have fingerprints comprised of living material that decayed thousands of years ago, the heat, pressure, and chemical makeup of the organic material in the geological mechanisms that produce oil, environmental weathering such as, evaporation, and of course the refining of the oil. By analyzing the specific groups within this chemical family and looking at their biomarkers you can tell them apart, which is key to finding the origin of oil spills.
Petroleum Hydrocarbons biodegrade easily is oxygenated environments, whereas Chlorinated Solvents biodegrade much slower and in nonoxygenated environments. Another thing to keep in mind is that as PHCs rapidly biodegrade it will seep into the soil and as Chlorinated Solvents biodegrade is releases toxins into the air. As PHCs enter soil and groundwater the condition stabilizes at the rate of it biodegrading. Chlorinated Solvents biodegrade slower and evaporate groundwater with it.
In conclusion, there are pros and cons to both chemical families. Chlorinated Solvents biodegrade slower and in nonoxygenated areas and Petroleum Hydrocarbons biodegrade quicker in oxygenated areas. When you introduce liquid PHCs and Chlorinated Solvents into water, they create a separate liquid phase due to being less dense than water. This is called nonaqueous phase liquids or NAPLs. These can affect soil gas or groundwater.

The History of Chinese Cultural Performances

There is a long history of Chinese cultural performances dating back to the dawn of the culture of this nation which gave the world many important events and types of performance. Chinese cultural performances are thought to date back over 5,000 years to the era of the Yellow Empire when Tao was developed, according to Shen Yun Performing Arts. There are many aspects of traditional Chinese culture you can explore from music to dance, gymnastics, and plays.

Early dance origins

The birth of artistic culture in China is thought to date back to the early religious movements which gave birth to folk dances and the historic performances we often see today. In early Chinese cultural performances, religious leaders and their followers would imitate the movements of animals which would influence generations of dancers for centuries to come. Asian Traditional Theater And Dance reports the tradition of Chinese cultural performances reflected the rigid social norms seen in the society which included the division of men and women. The culture of dance in China split performances into two forms, wu dances were performed by men and xi dances by women.

Dance dates back thousands of years

The arrival of dance as a form of cultural performance in China became popular as street performances extended across the nation with dancers, jugglers, acrobats, and other performances similar to those now seen in Chinese circus performances. The most famous of these performances are probably the iconic female dancers who are known for their long, fluttery sleeves. Drawings and sculptures of these images date back thousands of years to give a clue about the length of time this cultural form has been in use for.

Developing the play

Traditional dramatic plays began to be developed in China around the sixth century A.D. which incorporated dance, mime, and early dramatic acting. These plays can take many forms including that of the mask, which began with the story of a prince who has such soft features he is forced to wear a mask in public. These plays were created as a combination of dance, mime, and straight acting which creates a unique blend of the arts giving rise to the majority of modern Chinese cultural performances.

There are many different influences and themes explored in the majority of Chinese cultural performances which are still performed in the 21st-century. The influence of Chinese cultural performance is so dominating around the world that the moves used in traditional dance can be found in disciplines spread across the world. Both gymnasts and martial arts practitioners use moves born in the early years of Chinese cultural performances.

The Future of Anesthesia Technology

The anesthesiologist is typically the first person to enter the operating room in the morning. There is a long list of checks that need to be performed before patients can be brought into the room. There is a complicated mess of tubes and wires that surround patients. This leads to tech frustrations that go beyond the O.R. to affect multiple facets of the hospital.

Surgery-related services account for about 68% of hospital income, and this subsidizes some other areas that have a net loss of income. One minute in the O.R. can cost $147. This all exists in the context of patients that are sick and the stakes are high in the O.R. environment. O.R. technology needs to come into the 21st Century as many other technologies have. There should not be so many poorly-implemented designs with unnecessarily tangled tubes and wires.

The technology in the O.R. will inevitably address these concerns, and when this happens, the jobs of anesthesiologists will change. Open-loop systems will begin to change into closed-loop systems, which means there are fewer intermediary steps between finding problems and solutions.

A closed-loop system is self-regulating and adjustable. This type of system could allow anesthesiologists to set parameters, and the changes could be dealt with in an automated fashion. For example, if the patient’s blood pressure changes, the machine could automatically administer the needed solution to fix the problem while it is monitored by a person. Current research is looking into how to develop these types of systems that could speed up systems and provide greater success rates. This new technology could allow the field to evolve.

Anesthesiologists spend a great deal of time educating themselves in human pathophysiology in order to provide intervention for whatever a patient needs during the extremely stressful conditions of an operation. When the technology changes in the future with interconnected devices and closed-loop systems, anesthesiologists will be able to focus more of their attention on patients and less time fussing over complicated machines. More emphasis can be placed on problem solving, procedures, patient safety and physiology. Another possibility with increased technology is an ability to take care of multiple patients simultaneously.

In the future, there will be more care team anesthesia and certified nurses who perform the job. Hospitals are finding ways to use less expensive labor. Physicians are seen as a premium cost for performing this role, so it is expected that more Certified Nurse Anesthetists (CRNAs) will be in demand in the coming years.

With greater automation does not come greater risk. For example, the autopilot feature of commercial jets made the industry safer and more efficient. The average age of patients is increasing, which is placing greater demands on the medical field. When technology advances, the new challenges for anesthesiologists can be more effectively met.

EHR vs. EMR: Know the Difference

The acronyms EHR and EMR are often used interchangeably, and this may be a leading reason why many people don’t fully appreciate the distinction. The concepts are actually quite different in some significant ways. In order to clarify this, we’ll define each term and explore the advantages that each method provides.

What Is an EMR?

The acronym EMR stands for electronic medical record. This is the digital version of the traditional paper medical records doctors kept and not unlike the charts that hang bedside in a hospital. The EMR contains not just the medical history of the patient but the history of treatment. It allows a doctor or other medical professional to track data over time, identify patients who require a checkup or a particular kind of screening, evaluate blood pressure and many other parameters and so forth. An EMR is generally specific to a particular practice, hospital, clinic and so forth.

What Is EHR?

The acronym EHR stands for electronic health record. An EHR can and often does contain everything that an EMR does and then some. The purpose of an EHR is to go beyond basic clinical data to a more holistic view of the patient so that medical professionals can better assess the condition of the patient and advise treatments and other care. In addition, an EHR is often intended to be consumed and updated by more than just a single clinic, for instance. For a particular patient, it may be shared by a general practice, the practice of a specialist, a laboratory, a hospital and so on and so forth.

Advantages of EMR

An EMR combines everything a particular clinician needs to know about a patient. It also allows that clinician to track the condition and treatments over time. This continues until the patient is fully treated and even beyond that if measures must be taken to avoid relapses and the like.

Advantages of EHR

An EHR is patient-focused as well but in a more dynamic way. It allows an entire team of medical professionals to track a patient22, progress, treatments and so on. The clinician who still requires a very clinic-specific view of the data has access to that if need be, but the medical professional who requires a more bird’s eye view has that as well. It also helps to avoid duplication, such as a doctor ordering a test a lab had already conducted.

The difference between EHR and EMR may seem on the surface as but a single word. They are often lumped together and discussed as a single concept. Nevertheless, there is actually a great deal of difference, and more awareness of this would arguably be of benefit to the individual as well as the system at large.

What You Need to Know About Medical Marijuana

Medical marijuana, also known as Cannabis, is used for a wide variety of health conditions. There are people around the globe consuming it for chronic pain, cancer, epilepsy, and many other conditions. In fact, a 2016 study in the peer-reviewed Health Affairs journal revealed a decrease in medical spending of nearly $170 million over a three-year period that’s attributed to the use of medical marijuana.

Recent studies have revealed a decline in the number of prescription drugs used to treat a wide range of disorders where medical marijuana has been legalized. This includes psychosis, depression, anxiety, nausea, chronic pain, sleep disorders and even seizures. There has also been a reduction in the number of deaths across the United States from a prescription drug overdose.

While the laws surrounding medical marijuana are constantly evolving, as of 2019, 33 states allow the use of medical marijuana and more than a dozen states allow the use of cannabis derivatives. The reason why there is pushback concerning the legalization of medical marijuana is because under the Controlled Substances Act, it’s been classified as a Schedule 1 drug. This essentially means it’s unsafe and doesn’t have any medical use. There are many professionals in the medical community that disagree. In fact, there are many doctors that recommend its use for certain medical conditions.

The active compounds in medical marijuana are called cannabinoids. Delta-9-tetrahydrocannabinol (THC) is one of the compounds, and it’s the ingredient that causes a person to feel high. It’s believed that a compound known as cannabidiol (CBD) is the ingredient that has medical benefits; this particular compound doesn’t have any psychoactive properties. There has even been a report published by the World Health Organization (WHO) indicating that CBD is not harmful to the public.

Despite the fact that CBD is still listed as a Schedule 1 controlled substance, the report issued by WHO indicated that as an independent compound, CBD may be effective in the treatment of some cancers, as well as Parkinson’s and Alzheimer’s. As previously mentioned, the laws are constantly evolving, which is often in response to ongoing research. Ironically, the amount of research conducted is limited because of the government’s position on the safety of medical marijuana. One of the reasons why there’s a lot of controversy surrounding medical marijuana is because it contains many different compounds.

When considering the use of medical marijuana, as with any other treatment, it’s important to communicate with your doctor to ensure you’re making the best decision based on your unique situation. Even if you obtain medical marijuana from a dispensary that’s licensed by the state, it can impair your motor skills and thinking. This means you should never drive a vehicle while consuming medical marijuana.
