When it comes to Hubble Space Telescope advantages and disadvantages, there are a number of elements you will want to keep in mind. The main reason for examining these pros and cons is to determine whether or not a space telescope is really needed in this day and age. As you will discover, there are several elements to that issue that you will want to keep in mind.
Advantages Of Hubble Space Telescope
There are several distinct advantages to having the Hubble Space Telescope, which has been in operation for many years:
1. The earth’s atmosphere
The first advantage? You don’t have to deal with the atmosphere of the earth. In terms of being able to make detailed observations, you are going to find that the atmosphere causes a lot of problems, particularly in terms of murkiness.
2. The detail is absolutely extraordinary
When you can eliminate the atmosphere, you have a degree of clarity that is still largely unmatched. You will be able to capture detail in a truly impressive fashion.
3. It points to the potential of the space program
Although the Hubble Space Telescope is not without its disadvantages, the fact of the matter is that it has been more successful than not. If someone fails to see the need for a space program, someone else could point to the numerous successes of the Hubble Space Telescope.
Disadvantages Of Hubble Space Telescope
As mentioned before, the Hubble Space Telescope is not without its problems. While the telescope has produced some dazzling shots, it has also come with the following problems:
1. Operating in space
Not surprisingly, operating a telescope that is in outer space can be a hassle.
2. Time consuming
Regardless of the work that needs to be done with the Hubble Space Telescope, you can count on a long wait. This ties into the point mentioned above.
Since the Hubble Space Telescope is so expensive to maintain, it doesn’t have the luxury of being as large as some would like it to be.
4. Repairs are difficult
Any kind of repair work is going to prove to be difficult. This is due to not only the lengthy wait, owing to the distance, but it is also due to the challenges of working in space.
5. Out of date
Since you can’t update the instruments as much as you would like, you are going to find the software going out of date quite often. This can lead to a variety of performance problems.
Breastfeeding is the best time for babies and mothers. The babies get the most natural food they must have for healthy growth. Mothers don’t have to worry what to feed their babies. It is true that the incessant feedings and the complete dependence of the baby on the mother can be at times tiring and also a little uncomfortable but mothers of toddlers and slightly grownup babies know the pain of trying to feed solid foods to their kids. The gamut of choice and the lack of choice, the preference of the baby and the consciousness of impacts on health make it very complicated.
There is no dearth of baby foods out there. Dozens of companies make scores of foods for babies of different age groups. But many mothers are concerned if those are the healthiest choices. The debate over homemade baby food advantages and disadvantages cannot be equated with instant noodles or microwave dinners. The latter have been proven to be considerably unhealthy. Packaged baby food is not unsafe so the debate is not that simple. Homemade baby food is certainly more desirable for obvious reasons. Let us explore the homemade baby food advantages and disadvantages.
List of Advantages of Homemade Baby Food
1. Complete Control
With homemade baby food mothers know exactly what they are feeding their child. Whether it is rice or potatoes, fish or a fruit, mothers can decide what food to use, which ingredients to use to cook the food, how to cook it, how to serve it and also the quantity of the food that one must make. This completely sense of awareness and control is certainly desirable. No mother or father wants to be uncertain of the foods they would feed their kids. Homemade recipes are often passed down from one generation to another. Knowing that one has grown up well on such foods gives the assurance that the kid will also get equally nutritious and safe meals.
2. Rich in Nutrition
Nutrition is really a key difference between homemade baby food and packaged foods. There are many brands that make nutritious baby food but the nutrients are still richer in homemade recipes. Most packaged foods for babies are cooked in mediums subjected to very high heat. The very high heat is necessary to kill the bacteria. Not all bacteria are bad but they would spoil the food. To enhance the longevity or shelf life, companies are compelled to use high heat. Although the loss of bacteria is not concerning, the nutrients in the ingredients are lost when subjected to the high heat. At home, one doesn’t have to worry about as long a shelf life as companies. Hence, one doesn’t need the high heat, thereby preserving the nutrients. Feeding the child some food is not about ensuring calories but assuring the nutrients for optimum health and growth. The immune system will only get strengthened if the foods are rich in essential nutrients.
3. More Affordable
Homemade baby foods would always be more affordable than packaged foods or prepackaged meals. You can choose the produce you want, you can use your own produce perhaps from your organic garden, you can buy local and you can use seasonal produce. The costs will reduce dramatically when you make your own homemade baby food. Packaged foods may have some discounts from time to time or you may have special offers. Yet, they will remain more expensive.
4. Desirably Personalized
Homemade baby food can focus more on purees. Instead of a mishmash of a recipe or any meal that may have a dozen ingredients but no one is sure in what quantity, mothers can combine the foods they want and ensure a super nutritious meal. Packaged foods also limit the choices in terms of flavors or taste. The high heat ruins the natural taste of the foods used and the flavors are often artificial. Although safe and palatable in many cases, parents want to choose what kind of taste they wish a particular dish to possess when feeding a child.
List of Disadvantages of Homemade Baby Food
1. Limited Choices
Homemade baby food is entirely subjected to what is available in a place. Many regions across the country don’t have enough varieties of produce available in the local markets. Produce sourced from distant regions will be processed and they may not be completely safe or desirably nutritious. It is better to have more choices in the packaged foods category.
2. Inconvenient & Tedious
Cooking homemade baby food can be tiring. If both parents are working and there is no help at hand, then this is a tedious endeavor. Many mothers choose to cook in large batches and store the same according to the servings at different times of the day and night over several days. But then storage becomes a concern. It is also very likely that you would run out of recipes and your kids may not like what you would cook for them.
A high deductible health plan (HDHP) is basically a plan that has a higher deductible than a traditional insurance plan. While the monthly premium is lower, you do have to pay more health costs out of pocket before your insurance pays its share. As these are increasingly being offered by employers, what are the potential advantages and disadvantages of such a scheme?
List of Advantages of High Deductible Health Plans
1. You pay lower premiums
According to Towers Watson, three-fourths of employers now offer HDHPs – this is up 53% from years ago. Even if employees do not want such a plan, they might not have any choice. But the bigger question is why would anyone opt for an insurance policy that makes you pay a bigger amount? Well, plans such as the HDHP offer lower premiums. This simply means that you get to save more of your salary. The HDHP is also good for those who rarely get sick because they won’t even reach their deductible.
2. You can manage increasing health care costs
By offering HDHPs, employers hope that employees will take greater responsibilities in terms of their expenses. In this case, the patient will shoulder most of the bill. Knowing that, patients might look for MRIs that are less expensive, seeking doctors out to know whether they really need a particular test or not, and heading to the ER only when there truly is an emergency.
List of Disadvantages of High Deductible Health Plans
1. You will be hit with ridiculously high deductibles
The average deductible will be at least $1,300 for individual coverage while it’s $2,600 and up for a family. Some reports say someone can pay as much as $10,000 in deductibles. Big companies, on the other hand, offer different plan levels. Meaning there are plans with minimum deductibles as well as plans with higher ones.
2. You benefit more if you are young and healthy
Healthy living has become ever popular. We have more and more people opting to eat healthy and have a daily exercise routine in order to keep fit. After all, prevention is better than cure, right? The same concept goes into HDHP: if you are young and healthy, you get to save more money.
3. You might be tempted to skip necessary health care
With an HDHP, patients will have to pay out of pocket – and at a larger amount – before their insurer pays their share. This is believed to make you shop for cheaper alternatives when it comes to health care. However, that isn’t the case. A study by the NBER found that consumers are just skipping services such as colonoscopies and mammograms altogether. Those aforementioned services are supposed to be free under the Affordable Care Act.
We don’t like to spend our own money when it comes to health care. But if you’re stuck with a n HDHP, don’t forsake your health. You can find lower prices if you take the time to look around – there are tools that can make comparisons so it’s easier for you to decide where you’ll be getting services from.
You might have actually tasted the mouth-watering guava fruit or have at least heard about or seen it. Basically, this fruit comes from a plant that belongs to the Myrtaceae family that is commonly found tropical and sub-tropical regions. While it is usually eaten raw, it is also used in cooking, where it has been popular for making jellies, jams and juices. As more of its health benefits are revealed, this fruit is also increasingly becoming available in the western world. However, there are also drawbacks that you should know about when eating it. Here are the advantages and disadvantages of guava fruit:
List of Advantages of Guava Fruit
1. It reduces the risk of developing cancer.
This fruit has an anti-tumor property that has been linked to the presence of compounds, including quercitin, lycopene, vitamin C and various polyphenols, which act as potent antioxidants that neutralize free radicals generated in your body that can cause cancerous growth. In fact, there is strong evidence that demonstrates the potential of guava extract in preventing breast, prostate, colon, lung and skin cancer.
2. It will help improve your immune system.
As a rich sources of vitamin C—even richer than oranges—guava is said to have two times the circadian claim of vitamin C, which is carefully associated with bigger attention and amnesty in helping to deal with pathogens and infections. Its role in this aspect is also well attributed to its anti-inflammatory qualities and its adeptness to arrest anarchic molecules, such as prostaglandins, appearing in rheumatoid arthritis and other diseases.
3. It contains anti-aging properties.
This fruit is also getting affluent in vitamins A and C, as well as antioxidants, such as carotene and lycopene that helps with protecting your skin from accomplished lines and wrinkles. While old-age is a natural stage that we reach in life, we can prolong the process by consuming guava on a regular basis.
4. It is good for those suffering from diabetes.
Guavas are believed to have anti-diabetic properties, which have been mentioned way aback in Chinese medicine. An abstraction actually shows that the fruit can lower sugar levels in diabetic patients. Aside from this, the insulin-like action that guavas possess makes such fruits acutely acceptable for diabetic patients.
5. It helps with treating constipation.
It is said that a single guava fruit can fulfill about 12% of your circadian-recommended assimilation of fiber in the body, which is good for your digestive health. Its fiber can help with freeing up blocked digestive tracks, eventually abating constipation.
6. It improves heart health.
An article in the “Journal of Human Hypertension” shows that consuming guavas can improve the potassium and sodium antithesis of your body, which means that it is good for patients suffering from hypertension. Moreover, it is said to lower the levels of bad cholesterol and triglycerides, which are leading contributors to the development of heart disease, while increasing the levels of HDL or acceptable cholesterol.
7. It is good for the brain.
This fruit contains vitamins B3 and B6, as well as niacin and pyridoxine, which are known to help in improving your nerves and the brain.
List of Disadvantages of Guava Fruit
1. It can make you feeling frequently bloated.
Like other fruits, guavas are a classic trigger for bloating, as it is rich in a type of sugar, known as fructose. Unfortunately, our body is not well equipped to digest and absorb huge amounts of fructose. In fact, researchers believe that up to 40% of people are suffering from a condition referred to as fructose malabsorption, where this sugar is inefficiently absorbed in the small intestine. So, overconsumption of this fruit will make it just sitting in our stomach and cause bloating, which is caused by the gas produced by bacteria feasting on the fructose.
2. It can cause diarrhea or irritable bowel syndrome.
Due to fructose malabsorption, you would also experience diarrhea or messed-up digestion issues. As guavas carry seeds to make new plants, it is natural for them not to be fully digested by humans, as seeds are designed to survive transit and get deposited in new locations to grow new plants or trees.
3. It will cause you to always crave for sugar.
Overconsumption of this fruit will not only spike your blood sugar, but it will also make you unable to sustain it for very long. As you may have notice, your stomach would start growling again not long after you get a fill of this fruit. The reason for this is that it is not packed with much fat or protein that keeps us sated. While it helps us with fiber, it is not sufficient to prevent a crash in our blood sugar after eating it.
4. It is prone to bacterial contamination.
Like other fruits on display, guavas could be exposed to a plethora of bacteria, such as listeria, E. coli and salmonella, which can attach to the fruits from the wind, water and soil. While they may have a tough exterior to keep bacteria out, it can be penetrated and contaminated if the skin is broken. And for the case of the guava, you would eat it raw with the skin, so your chance of ingesting bacteria can be high.
5. It is not always available.
According to experts, many people eat sufficient amounts of fruits in their daily diets to reduce their risk of developing certain health conditions, with the help of their healthy contents. Unfortunately, fresh fruits, including guavas, are not always available in many places, and if they are, they would be expensive to buy. This is especially true for guavas, considering that they are only grown in tropical and sub-tropical regions, making them scarce in other parts of the world.
As with many other fruits, eating guava fruit in its natural form is very healthy, though it also comes with some risks. With these lists, you will be able to build a well-informed opinion whether the fruit is entirely good for you, or not.
We sneak a bit of green into our meals to make it healthier. But what works for food doesn’t always agree with drink. Adding greens into smoothies isn’t quite as palatable as incorporating them in food. However, simply searching on the internet for delicious green smoothies will yield many results. The only thing left to do is try them to see if it really is tasty.
Sure, including a green smoothie into your diet is healthy but are there any drawbacks to doing so?
List of Advantages of Green Smoothies
1. It is a simple way to consume more healthy foods
A smoothie can be a combination of a number of produce. All you need is a blender and a combination of your favorite fruits and vegetables. After all, we’ve always been told to eat healthier, so what better way to do so than to put all those healthy goodness into one drink? If you’ve always struggled to include low-calorie produce into your diet, this is one of the easiest ways to do so.
2. It has more dietary fiber
A green smoothie diet is high in dietary fiber and as such, has many health benefits. For one, it can balance blood sugar and cholesterol levels. Plus, it encourages the consumption of healthy foods such as fruits and vegetables. Preparing a green smoothie also doesn’t take a lot of time and is fairly simple as well.
3. It can help with weight loss
A green smoothie diet is low in calories. As such, those who subscribe to it have a good chance of dropping weight. Of course, it’s always best when done in conjunction with exercise.
4. It is available in many food establishments
Many people are now embracing the green revolution and many food establishments are taking notice. There are even stores dedicated to just making healthy drinks. So if you were too busy to whip up your own, you can always get one from a healthy eating establishment.
List of Disadvantages of Green Smoothies
1. It may not yield the best results taste-wise
Preparing a green smoothie is basically a hit or miss. Combining fruits and vegetables as well as other ingredients can taste fantastic or disgusting. Although you can always practice good combinations, some really tasty recipes can be found online. You might have to make some minor adjustments to suit the taste to your preference but at least, you’re not alone in this matter.
2. It is costly
Experimenting with food and having it yield an unsavory result definitely hurts your pocket. Even following recipes isn’t a guarantee the turnout will be delicious. It takes time to find the perfect recipe that not only tastes good but also contains much needed nutrients.
The good thing about green smoothies these days is you can buy them from establishments that encourage healthy eating. That being said, making your own is definitely better. It may take experimenting to get the flavors just but it may just save a whole lot more time on your part.
Green olives are harvested during the cycle when the fruits ripen and at their normal size, yet prior to color change. Usually, they are hand-picked by the time they show a slight change in hue, from leaf-green to yellowish green, which indicate that their flesh is starting to change consistency before it turns soft. Today, there are trials run to machine harvest green olives, but due to the high percentage of bruised fruits that comes with such a method, they need to be immersed in an alkaline solution while still in the farm. Then, the fruits are transported to the plant to be processed on the same day as much as possible.
Now, many people are consuming green olives for the benefits that they bring, but there are also unfavorable effects these organic food sources have that we should not ignore. Here are their advantages and disadvantages:
List of Advantages of Green Olives
1. They can help with weight loss.
The monounsaturated fats, which are found in these types of olive, are believed to encourage weight loss. According to research, oil extracted from them helps with breaking down fats inside fat cells, reduce insulin insensitivity and get rid of belly fat. People who are known to consume high amounts of olive are found to eat fewer calories overall, thus are rarely overweight. Their blood tests also show they higher levels of serotonin, which is referred to as “satiety hormone” that makes people feel full. Also, olive oil aroma can have the same effect on the body, cutting calorie intake.
2. They offer cardiovascular benefits.
When cholesterol is oxidized by free radicals, it will damage blood vessels, causing fat to build up in arteries that can lead to heart attack. Now, the antioxidants in olives will impede this oxidation process, thus helping to prevent heart disease. Though olives do have fat content, it is the healthy monounsaturated type that has even been found to increase good cholesterol and lower the risk of developing atherosclerosis.
In fact, research show that, when a diet is altered to increase monounsaturated fat content, yet no too high in terms of total fat, participants typically experienced a decrease in LDL cholesterol, blood cholesterol and the ratio between LDL and HDL. Other than this, studies also show that the monounsaturated fat found in green olives and their oil extract can help with decreasing blood pressure, with the oleic acid being able to change the signaling patterns at a cell membrane level, particularly altering the G-protein-associated cascades, once it is absorbed into the body and transported to the cells.
3. They help with preventing cancer.
The anti-inflammatory and antioxidant properties of green olives make them a natural solution for protecting yourself against cancer, considering that chronic inflammation and chronic oxidative stress are among the key factors in the development of cancer. As you can see, if our cells get overwhelmed by oxidative stress and chronic excessive inflammation, you will be at an increased risk of developing cell cancer is increased.
4. They are good for the eye.
It is said that a single cup of green olives contains 10% of the daily recommended allowance of vitamin A that is converted into retinal form, which is essential for healthy eyes. Basically, this vitamin enables your eyes to better distinguish between light and dark, thus improving your night vision. Moreover, it is believed to be effective against macular degeneration, cataracts, glaucoma and other types of ocular diseases related to age.
List of Disadvantages of Green Olives
1. They can cause diseases associated with trans and saturated fats.
While it is said to be good, oil from green olives is also said to be like other processed foods, which are partially hydrogenated or refined under high pressure and heat, altering their molecular structure and burning the healthy omega-3 fatty acid that is contained in olives. Now, this can affect the cholesterol levels in the bloodstream by decreasing good cholesterol and then increasing the bad ones, raising the danger of cardiovascular diseases in the long term. Olive oil is heavily rich in monosaturated fat, that using only 2 tablespoons of it in one serving would mean taking in a huge amount of saturated fatty acids, which is many times higher than those of other foods. Generally, very high amounts of saturated fat can increase the risks of developing deadly diseases, such as obesity, atherosclerosis, stroke, heart attack and certain types of cancer.
2. They can cause low blood sugar and pressure.
While it may sound strange, oil from green olives can actually lower blood sugar levels below normal, which can make you prone to some types of health complications, including excessive sweating, hypoglycemia, trembling and feeling weak. And while olive oil is believed to keep the heart healthy, some research show hat overconsumption of it can cause a huge fall in blood pressure, which will also make you vulnerable to a number of health issues, including lightheadedness, dizziness, kidney failure and stroke, among others.
3. They increase the chances of inflammation.
As they are loaded with fat, green olives can increase your chances of developing inflammation. Basically, they contain huge amounts of oleic acid, which plays a key role in releasing the lipopolysaccharides (LPS) from the gut into the bloodstream. And, the more the LPS present in your blood, the higher the extent of inflammation that will be caused.
4. They can cause diarrhea.
The high content of fat in green olives oil is known to trigger gastrointestinal problems and cause digestive disorders, such as diarrhea. When you consume them in huge amounts, your system would be unable to digest them completely, which normally results in minor to moderate diarrhea. And as natural laxative, olive oil can even make the situation worse.
With these lists of advantages and disadvantages, you will be able to know whether or not green olives are right for you. If you think that you do not have the risk factors, then go ahead and enjoy the nutritional benefits that they bring!
The Agricultural Marketing Service of the USDA defines grass fed as grass being the only “feed source consumed for the lifetime of the ruminant animal” and that the animals “cannot be fed grain or grain by-products.” On the other hand, the diet of conventional beef cattle may include grains.
The nutrients we get from beef depend on the diet of the animal. In short, we may be getting more if cattle is under one kind of diet and get less from the other. But is feeding cattle only grass truly beneficial? Are there any drawbacks at all?
List of Advantages of Grass Fed Beef
1. It is healthier and tastes better
Grass fed beef has more nutrients. Cattle that are fed only grass will have a range of flavors and the meat is very rich. Not only that, there will be taste differences as well depending on where the animal was raised. There are other health benefits of grass fed beef and these include:
more omega-3 fatty acids (which are good for the heart)
more conjugated linoleic acid (helps reduce risk of heart disease and cancer)
more antioxidant vitamins like vitamin E
Eating lean beef containing 10% fat or less has always been recommended – it makes up a heart-healthy diet.
2. It benefits the animals
Feeding grain to cattle creates a lot of stomach issues. If it’s uncomfortable to humans to walk around with stomach pain, the same goes for animals.
3. It is better for the environment
Raising animals out of confinement can reduce environmental footprint compared with beef that has been grain-fed. Grazing on grass minimizes the growth of woody plants that make grasslands inhospitable to grass.
List of Disadvantages of Grass Fed Beef
1. It is more expensive than regular beef
There are more packages of grass-fed beef in grocery stores these days and when you compare their prices to standard supermarket beef, you’ll notice that they are more expensive. The meat is pricier because it takes a while for farmers to get cattle to their desired slaughter weight. Grass fed cattle also tends to be smaller, meaning there will be less meat.
2. It isn’t proven to be healthier
There isn’t enough evidence to prove that grass fed beef is indeed healthier. Research is limited on whether or not cattle raised on grass alone are truly healthier than conventional beef.
3. It is harmful for the environment
Some say that grass fed beef is beneficial for the environment but there are others who argue against it. Their reason: consuming beef adds more damage to the environment than driving a car to and from work. Scientists at the National Institute of Livestock and Grassland Science in Japan estimate that 1 kilogram of beef emits more greenhouse gas than 155 miles of driving.
Grass fed beef has its own fair share of advantages and disadvantages. Consumers who have the means are the only ones who can afford grass fed beef. That being said, eating conventional beef is also better than consuming junk.
Gram staining, which is also referred to as the Gram’s method, is a scientific technique of staining that is used to differentiate the species of bacteria into 2 main groups, namely the gram-positive and the gram-negative bacteria. The differences between these groups of bacteria are considered to be important in determining appropriate treatments for infections.
Developed in 1884 by Danish physician Hans Christian Gram, this method is considered as the most important procedure in microbiology and is still the cornerstone of bacterial identification and the taxonomic division. Basically, a gram stain is a kind of laboratory or microbiology test that is performed to determine whether bacteria are present on a variety of specimens, which include tissue, blood, sputum and stool. While it is generally seen as having a lot of perks, this procedure also has its own set of drawbacks that is also important to look into. Here are the advantages and disadvantages of Gram staining:
List of Advantages of Gram Staining
1. It gives quick results when examining infections.
In most cases, Gram stains are performed on biopsy or bodily fluids when infection is suspected, and they yield results much more quickly than other methods, such as culturing. This is especially important when infection would make a crucial difference in a patient’s prognosis and treatment, such as testing synovial fluid for septic arthritis or cerebrospinal fluid for meningitis.
2. It is simple and cost-effective.
This general stain is observed as the simplest, least expensive and most useful among the quick methods that used extensively in microbiology for the preliminary differentiation, identification and classification of microbiological organisms. The procedure is performed to produce precluding information regarding the type of organisms that are directly present from the clinical specimens or from the growth on culture plates. Unlike some other alternatives, it is cost-effective in identifying the presence of microorganisms in normal, sterile body fluids.
3. It helps with determining appropriate treatments for infection.
In some cases, it would not be clear whether an infection is caused by bacteria, fungi or viruses, and these kinds of infection would be treated in different ways. Now, a Gram stain will let physicians determine whether a certain type of bacteria is causing the infection and what type of microorganism is present. This is why any person who is suspected to have bacterial infection or actually is having one is a candidate for a Gram staining test. The doctor would order this along with a culture if an individual is showing symptoms of infection.
4. It allows for various methods of testing.
To be able to perform a Gram stain test, there is a need to have a sample of body tissue or fluid, and the collection methods would vary depending on the types of the sample. For mucus or sputum, a patient is allowed to cough up a sample into a specimen container, and in other cases, a blood sample will be collected using a blood draw.
5. It is basically a key procedure in identifying bacteria.
As mentioned above, this method is a very important step in the preliminary characterization and classification of bacteria, and it is a key procedure in identifying bacteria based upon staining characteristics, which enables the bacteria to be examined with the use of a light microscope. Keep in mind that bacteria, which are present in an unstained smear, will be invisible when you view it using a light microscope, but once stained, their arrangement and morphology will make it able to be observed. Moreover, Gram staining is also an important step in the screening of infectious agents that are found in clinical specimens, such as a patient’s direct smear.
List of Disadvantages of Gram Staining
1. It has significant limitations when used for environmental microbiology.
The Gram stain is definitely not an infallible technique for identification, diagnosis or phylogeny, and it faces extreme limitations when used in environmental microbiology. While it is used primarily for making a preliminary morphologic identification or for establishing whether there is a substantial number of bacteria in clinical specimens, this method will not be able to identify bacteria to the species level. For medical conditions in most situations, it is not recommended as the sole method to use for bacterial identification. In laboratories for clinical microbiology, this method is used in combination with other molecular and traditional techniques in identifying bacteria.
2. It has a few side effects.
It is noted that Gram staining has a few side effects that can occur depending on the method used for obtaining samples and the type of samples. While some types of samples, such as stool, would not entail certain side effects, blood samples would lead to side effects, such as bruising, because of the blood draw.
3. It comes with certain types of risks.
Though there are no known risks of performing a Gram stain with some samples such as urine or mucus, one that uses tissue samples will carry a few risks related to the removal of tissue, such as infection or excess bleeding.
4. It might lead to misinterpretation.
During the process of staining, the iodine and crystal violet would form a complex within the heat fixed cell, and in organisms that are gram-negative, this complex would be readily washed out by agents, such as alcohol or acetone, but would appear red as they retain only the counterstain. On the other hand, gram-positive organisms would retain the complex after decolorization and would remain purple. This would result to over-decolorization from the loss of the complex and, eventually, misinterpretation.
Infections caused by bacteria should not be ignored even the symptoms are just mild, and one of the most commonly used methods to do this and find some treatments to address severity and spread is Gram staining. As you can see, ignoring infections can eventually lead to tissue and organ damage. However, based on the advantages and disadvantages listed above, do you think this method is best to use instead of some other alternative techniques to attain similar results?
As their name implies, geothermal power plant stations use geothermal energy — that is, the heat that comes from the earth. These stations obtain the earth’s heat by drilling steam wells or water wells, and they use this energy to heat water or any other type of fluid. This, in turn, is used to turn generator turbines, producing energy that is then distributed to consumers. The fluid is then cooled using a condenser and returned to the earth.
Geothermal power plant stations bring about several benefits, but they also have their own drawbacks. Check out the lists below to learn about their advantages and disadvantages.
List of Advantages of Geothermal Power Plant Stations
1. They are relatively environment-friendly
Unlike coal-powered plants, geothermal power plant stations use a renewable heat source that has a steady supply. In fact, the amount of heat they extract is only a small portion of the amount of present in the earth’s core. Studies have also shown that the industry has tapped only 6.5 percent of the overall global potential, meaning there’s enough energy to power the world for many more years to come. On top of that, the amount of greenhouse gas produced by geothermal power plant stations are only five percent of what coal-powered plants emit, meaning the former are much better for the environment than the latter.
2. They produce large amounts of energy.
One of the biggest advantages of these geothermal power plant stations is that they have a large power capacity. This means that they can greatly help in meeting energy demand, which is rising every year both in first-world countries and developing nations.
3. They result to stable prices.
Conventional power plants are dependent on fuel, so the cost of the electricity they produce fluctuate according to the market price of fuel. This isn’t the case with geothermal power plant stations; since they don’t use fuel, they don’t have to rely on fuel prices and they can offer their consumers stable electricity costs.
List of Disadvantages of Geothermal Power Plant Stations
1. They can’t be built just anywhere.
Although the earth’s heat is found almost everywhere, prime locations (i.e. those have all the components needed to support geothermal power plant stations) are only found in selected areas. These areas are usually far away from urban and industrial communities, which are the places that have the highest need for electricity. Because of this, certain infrastructure would have to be built before the electricity that the plants produce could reach the consumers.
2. They can be expensive to build.
Geothermal power plant stations require specially designed heating and cooling systems and other equipment that can withstand high temperatures. As mentioned above, they’re also usually located in isolated areas, and enough money is needed to build the appropriate infrastructure that would deliver electricity from these far-flung areas to populated communities.
3. They can cause environmental damage.
Although geothermal power plant stations are more environmentally friendly than other energy stations, they can still cause some damage. One of these is their high consumption of freshwater, which is heated to power generator turbines and can make potable water more scarce for people. The fluids that are drawn from the earth through the drilling process contain high amounts of toxic chemicals (including arsenic and mercury) as well as greenhouse gases (like methane and radon). If these are improperly disposed or handled, they can escape into the atmosphere or seep into the water table and wreak havoc on the environment and on people’s health.
Geothermal power plant stations are already existing in many countries around the world. Still, it’s worth considering the advantages and disadvantages above to ensure we reap the benefits of these stations while minimizing their drawbacks.
Geothermal heating is the process of using the earth as a heat source or a heat sink. Specifically, it obtains heat from the earth to warm homes and other buildings during winter. In the summer, the system deposits heat into the earth to make domestic and commercial structures cooler. Geothermal heating usually uses a special pump to accomplish these tasks, and it’s often paired with solar heating to create a more efficient system.
Like any other heating and cooling system, geothermal heating comes with both pros and cons. Some of them are listed below:
List of Advantages of Geothermal Heating
1. It helps lower electricity bills.
Most geothermal heating systems can meet 60 to 80 percent of a building’s overall demand for electricity (the remaining 20 to 40 percent is provided by another source, such as propane or mains electricity). The amount of electricity that geothermal systems can generate is enough to lower utility bills and help homeowners and tenants save a substantial amount of money.
2. It harnesses renewable energy.
Geothermal heating uses the energy generated by the earth, which is considered to be renewable since it’s always present as long as the earth is still standing. This makes geothermal heating a more environmentally option compared to other forms of heating and cooling systems, particularly true for those that use coal, gasoline, and other fossil fuels.
3. It can last for years.
As long as a geothermal heating system is properly designed and built, it has the potential to last up to 50 years. This makes it a sound investment, especially for those who are planning to live in their home for a long time.
List of Disadvantages of Geothermal Heating
1. It requires electricity to function.
Even if a geothermal heating system meets most of a building’s energy demands, some of these demands are met through other means, such as electricity that’s produced through fossil fuels plants. These plants are only 30 percent efficient, which means the energy they produce can cancel out the environmental gains that geothermal heating provides.
2. It can be costly.
A geothermal heating system requires a specialized pump as well as other equipment. It must also be installed by fully trained and certified geothermal heating experts who know how to properly set up the system. All of these can result to high initial costs, which are between $5,000 to $20,000 for domestic systems — an amount that not all homeowners can afford. The only consolation to this is that the high upfront cost can be offset over time through substantial savings on utility bills as well as the fact that the system can stay functional for decades.
3. It can affect water tables.
A type of geothermal heating system called ground loop system requires water to be pumped out of the ground to maintain the right temperature and ensure the heat pump doesn’t freeze. Unfortunately, this can lower the water table in the area over time and makes it difficult to obtain fresh, potable water.
Geothermal heating comes with a wide range of benefits, but the disadvantages must also be considered to minimize the damage that they bring.
