The Facts on Alcohol Use Disorder

The Facts on Alcohol Use Disorder Addiction Alcohol Use Print The Facts on Alcohol Use Disorder By Buddy T facebook twitter Buddy T is an anonymous writer and founding member of the Online Al-Anon Outreach Committee with decades of experience writing about alcoholism. Learn about our editorial policy Buddy T Updated on December 01, 2019 Phil Ashley/ Getty Images More in Addiction Alcohol Use Binge Drinking Withdrawal and Relapse Children of Alcoholics Drunk Driving Addictive Behaviors Drug Use Nicotine Use Coping and Recovery Alcohol abuse is the overuse or misuse of alcohol. It is defined separately from alcoholism. While they may exist together, alcohol abuse does not necessarily include some of the hallmark characteristics of alcoholism, which include an extremely strong craving for alcohol, tolerance, loss of control, or physical dependence. Defining Alcohol Abuse It is common for people to deny that they have an alcohol abuse problem. Furthermore, you may not recognize the signs of alcohol abuse in yourself or in someone else. DSM-5 Definition of Alcohol Use Disorder The 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), which is produced by the American Psychiatric Association (APA) was most recently updated in May 2013. In this manual, which serves as the reference for the psychiatric and medical community, a new condition called alcohol use disorder was formally defined for the first time. Alcohol use disorder replaced the designations that had previously been separately defined as alcohol abuse and alcohol dependence. Alcoholism remains a separate disorder, with its own criteria. The DSM-5 provides a list of 11 symptoms of alcohol use disorder. Alcohol use disorder is sub-classified into mild, moderate, and severe categories. Alcohol use disorder is considered mild if you exhibit two or three of the 11 symptoms, moderate if you display four or five symptoms, and severe if you display six or more of the symptoms on the list. Alcohol Use Disorder Diagnostic Criteria Symptoms of Alcohol Use Disorder 1. You drink more alcohol than intended to or continuing to drink for a longer period of time than you had intended. 2. You decide or trying to  cut down or control your alcohol use without success. You may return to drinking after a period of  abstinence. 3. A significant amount of your time is spent in obtaining alcohol, drinking alcohol, or recovering from the effects of drinking, resulting in too much of your time devoted to alcohol. 4. You have a craving for alcohol, which you might also describe as a strong desire or urge to use alcohol. 5. Your recurrent alcohol use results in a failure to fulfill some of your major obligations to your family, at home, at your job, or at school. 6. You have problems with family, friends, or co-workers as a result of your alcohol use and you continue to use alcohol use despite these persistent or recurrent social or interpersonal problems. 7. You have reduced or given up some of your social, work, or recreational activities because of your alcohol use. This is often described as drink-seeking behavior and includes decisions such as only going to social events that will include drinking, or only hanging out with others who drink. You may do this to avoid stigma, escape judgment from others, save your money for alcohol, or because you prefer to spend your time drinking over participating in other activities. 8. You repeatedly use alcohol in situations that are dangerous, such as swimming, driving, or using specialized equipment. Using alcohol in situations that leave you vulnerable to attack by others also fits this criterion. 9. You continue to use alcohol despite negative emotional effects, such as depression, anxiety, or memory lapses that you believe to be caused, exacerbated, or related to your alcohol use. 10. You have developed or are developing alcohol tolerance, which means having to drink increasing amounts to achieve previous effects. Tolerance is defined by either of the following: a) A need for increased amounts of alcohol to achieve intoxication or desired effect, or b) diminished effect with continued use of the same amount of alcohol. Some people consider tolerance as a sign of maturity or being able to hold their alcohol. However, this is an erroneous conclusion, as tolerance is not a sign of healthy physical function. 11. If you experience either of the following, then you have problems with alcohol withdrawal: a) You have withdrawal syndrome, which includes physical symptoms, such as shaking, jitteriness, irritability, sweating, or perceptive disturbances (like hallucinations) after going a short period without drinking, or b) You may drink alcohol or use a substance such as a benzodiazepine to relieve or avoid withdrawal symptoms  or to cure a hangover. Alcohol Use Disorder and Alcoholism Many effects of alcohol use disorder are also experienced by people who suffer from alcoholism, and there is a great deal of overlap between the conditions. It would not be accurate to say that one disorder is better or worse than the other, or that it is easier to recover from one or the other. What an Alcohol Use Disorder Diagnosis Means

Learn About Scarab Beetles of the Family Scarabaeidae

Scarab beetles include the biggest insects in the world, in terms of sheer mass. Scarabs were revered in ancient Egypt as symbols of resurrection. More than just powerhouses, scarab beetles serve important roles in the habitats where they live. The family Scarabaeidae includes dung beetles, June beetles, rhinoceros beetles, chafers, and flower scarabs. What Are Scarab Beetles? Most scarab beetles are robust, convex insects with brown or black coloring. Whatever the coloration, size, or shape, scarabs share a key common feature: lamellate antennae that can be closed tightly. The last 3 to 7 segments of each antenna form plates that can be expanded like a fan or folded together into a club. Scarab beetle larvae, called grubs, are c-shaped and usually live in the ground, feeding on roots. The grubs have a distinctive head capsule, and easy to identify legs on the thorax. The family of scarab beetles falls into the following classifications: Kingdom - AnimaliaPhylum - ArthropodaClass - InsectaOrder - ColeopteraFamily - Scarabaeidae What Do Scarab Beetles Eat? Most scarab beetles feed on a  decomposing matter such as dung, fungi, or carrion. This makes them valuable in their environments as they are a bit like the cleanup crew or garbage haulers of the animal kingdom. Other scarab beetles visit plants, feeding on pollen or sap. Flower scarabs are important pollinators, for example. Larvae feed on plant roots, carrion, or dung, depending on the type of scarab. The Life Cycle of Scarabs Like all beetles, scarabs undergo complete metamorphosis with four stages of development: egg, larva, pupa, and adult. Scarab beetles generally lay their eggs in the ground, in dung, or in other decomposing materials including carrion. In many species, the larvae feed on plant roots, though some feed directly on dung or carrion. In areas with cold winter climates, grubs typically move deeper into the soil to survive freezing temperatures. They then emerge as adults in early summer. Special Adaptations and Defenses Some male scarabs, such as rhinoceros or Hercules beetles, bear horns on their head or pronotum (the hard dorsal plate covering the head-body junction). The horns are used to spar with other males over food or females. Dung beetles excavate burrows below manure piles, then mold the dung into capsules in which they lay their eggs. The mother cares for her developing young by keeping the dung ball free of mold or fungi. The June beetle (or June bug) feeds at night and is attracted to light, which is why theyre often seen on warm evenings in early summer. The female can lay up to 200 small pearl-like eggs and the larvae feed on plant roots for three years before emerging as adults. Some plant-eating scarabs such as the rose chafer are poisonous to chickens and other poultry who eat them. Range and Distribution Some 20,000 species of scarab beetles inhabit terrestrial habitats around the world. Well over 1,500 species of Scarabaeidae live in North America.

My Most Embarrassing Moment Free Essays

My Most Embarrassing Moment Some things are easier to remember, than to forget. I can remember my most embarrassing moment as if it happened yesterday. I’ve tried to forget about this moment all my life, but it just never goes away. We will write a custom essay sample on My Most Embarrassing Moment or any similar topic only for you Order Now I can think back to that day and just laugh. I was nine years old, and I was attending elementary school. I was starting my fourth grade year with no friends. I was a quiet and shy person, so I never hung out with the other kids. After a few months I manage to make friends and wasn’t so shy anymore, until one day. It was Monday December 10, 1999. Like any other day I got up and ready for school. I notice that it was very cold outside, so I asked my mom to drop me off at school. On my arrival, I immediately entered the school and went downstairs to the cafeteria, where I met with some of my classmates. Time passed by and the first bell ran and everyone including myself started heading upstairs to homeroom. My homeroom was on the 4th floor. I used to hate this because by the time I would get to the 4th floor, I would be tired and running out of breath. While trying to my catch breath, I had to walk all the way down this long hallway, just to get to my classroom, which was room 313. I finally got there, and immediately went inside the classroom, and said â€Å"hi† to my teacher Miss. Fitzgerald. I sat down in my assign seat, which was the first seat on the second row. As we were waiting for the rest of the class to come in, my friend Raul, who was sitting behind me said â€Å"hi. † He usually didn’t talk to me, because I was too shy. And I didn’t talk to him, because he was consider the cutes boy in my class, who every girl used to like. But to me he was just like any other boy who pretended to be a young Justin Timberlake, but with no fame. We exchanged a few words and then the teacher begun to lecture. Hours when by and it was finally time for lunch. After forming a line, we started to go downstairs to the cafeteria. As we went down, I started to smell the food, which that day we were having pizza. It smelled like juicy cheese melting down in warm tomato sauce! I couldn’t wait to sit and eat. Shortly after that, it was time to return to class. Once again, we made a line and headed upstairs. As we got to the fourth floor, I felt someone touch my butt. I turn around quickly to figure out who had touched me inappropriately and the only person I saw behind me was my friend Raul. I didn’t know what to do, my heart was pumping like if I had just gotten chase by zombies. I was so scared that I started to cry. Everyone gazed at me, wondering what was wrong. In the meantime, my teacher Miss. Fitzgerald kept asking me in a loud tone of voice, â€Å"What is the problem Coyna? † I didn’t want to answer her in front of the whole class. She then kept asking me the same question in louder tone of voice. I had no choice, but to tell her out loud, â€Å"Raul touched my butt! † At the moment, my body went numb. My face turned red as a strawberry. I was so embarrass because no one has ever touched me like that before. Everyone kept looking at me with eagle eyes, as if I was their prey hunt. In my mind I just keep saying â€Å"oh my god why did this happened to me and why are all eyes on me†. I felt so uncomfortable that I wanted to hide under a rock and not come out in years. We finally got to the classroom where Miss. Fitzgerald ordered the rest of the class to go inside. She then asked Raul if what I was saying was true, and Raul denied everything making me look like a liar. Consequently, the teacher didn’t do anything but give Raul a warning. Afterward, I felt very embarrass and didn’t talk to anybody for a whole week, including the teacher. Finally, every time I think about this experience in Elementary School I can’t help myself but to laugh. I was only nine years old in the fourth grade, who would had thought that something like this could had happen to me. It was not a pleasant situation; I just wish I was matured enough to handle it differently. However, I was fortunate enough to learn from such experience, even though I am still embarrassed about that day. Just remember that what happens unexpectedly stays forever as a memory.

Specific heat capacity is ethanol Essay Example

Specific heat capacity is ethanol Paper The three variables that affect the specific heat capacity of a substance are:   emperature change (K) or ( c) The equation that is used to determine the specific heat capacity of any substance is; Specific Heat Capacity = Energy Supplied ( Q) (C) Mass (kg) Temperature Change ( ) Unit: Jkg- K- Each different substance have different specific heat capacity, this is because different substances require different amount of energy to change the to increase or decrease the temperature. As all substances have different Internal Energy, this explains why different substances require different amount of energy to change the temperature. Studies from A2 explain that Internal Energy (Thermal Energy) is the sum of the kinetic energy and the potential energy of the molecules in an object or substance. If the temperature of a substance increases so does the internal energy. Referring back to knowledge gained from A1 when a substance is at a liquid state it has more internal energy than a substance at solid state. This can be explained by the fact that at solid state particles are bonded together so the particles movement is restricted. At liquid state the particles are spaced out s they are able to move randomly so they have more internal energy than particles in a solid, which have their movements restricted. As particles in solids are bonded together this means that heat can be conducted from one particle to another easily. Conduction transfers thermal energy through the collision of neighbouring particles.

The way heat is transferred in liquids is through convection. Convection is the heat transfer due to the current movement from warmer particles moving towards the section where cooler particles are and cooler particles moving towards the warmer section of a fluid, this is caused by different densities at different temperature. This explains why liquids tend to have higher rates of specific heat capacity compared to solids because heat is transferred much quicker through conduction than convection. If you compare the specific heat capacity of copper, (390Jkg- K- ) to the specific heat capacity of water, (4180Jkg- K- ) there is a significant difference. In general the specific heat capacity of a solid is significantly lower compared to most liquids expect from Mercury which has a specific heat capacity of 140Jkg- K- when is in a liquid state. This also explains why H O has a low specific heat capacity when its in solid state, ice. (2100Jkg- K- ) compared to when its in liquid state, water (4180Jkg- K- ) From my research I found out that there are two laws of Thermodynamics: The first law states that the net heat transfer ( Q) of a systems equal to the sum of the thermal energy. The second law states that the entropy of an isolated system never decreases. This means that heat cannot be 100% converted to useful energy because the heat released to entropy is never returned to the system. Entropy is like internal energy; it is a thermodynamic quantity that belongs to any system of objects. It is proportional to temperature. As the temperature increase, entropy increased. In a microscopic level, entropy measures the amount of disorder in a substance. When heat is added to the substance, the particles that make up the substance move faster in a random way. The greater the velocity of the particles this implies more disorder for the substance; therefore increasing its entropy. To work out how much energy is used Power and Time are required: This is the equation t work out Power: Power = Current   voltage. Thus to work out energy we use this equation: Energy = current   voltage time The substance that I will be trying to determine its Specific Heat Capacity is Ethanol. Ethanol, C2H5OH is the second member of the aliphatic alcohol series. Most of the ethanol used is a mixture of 5% water because pure ethanol known as absolute ethanol is too expensive. Ethanol is prepared by a 95% solution, which results from the fermentation of sugars. Ethanol used in industry is made by reaction of ethane and steam. C2H4 + H2O= C2H5OH Ethanols has a boiling point of 78. 3 degrees centigrade, which is lower than waters boiling point. PREDICTION.
