Psychotic Features Of Bipolar Disorder - 857 Words
Bipolar I disorder with psychotic features is a mood disorder often described as excessively cheerful or disturbed moods, along with depression or a mix of high and low moods. For individuals with bipolar I disorder with psychotic features, they must have experienced at least one or more manic or mixed episodes during the course of their illness. A manic episode is a period of abnormally and persistently elevated, excitable or irritable mood lasting for at least one week and present most of the day. Other symptoms include inflated self-esteem or grandiosity, more talkative than usual or pressured speech, racing thoughts, decreased need for sleep, distractibility, increased in goal-directed activity and excessive involvement in activities that could have a high potential for painful consequences. A person with mixed episode can be diagnosed when a person experiences both a manic episode and a major depressive episode, promptly alternating with each other. A major depressive episode includes symptoms such as depressed mood, increased restless or decreased physical activity and feelings of worthlessness, among others. The presence of psychotic symptoms in bipolar disorder places an individual at the severe end of the diagnostic spectrum, meaning that the individual exhibits more than the number of symptoms required to make the diagnosis. Also, these symptoms significantly interfere with his ability to function in his job, socially or within his relationships.

A Journey To The Center Of The free essay sample
Earth Essay, Research Paper In the novel, A Journey to the Center of the Earth, writer Jules Verne tells the fabricated narrative of three work forces and their escapades as they descend into the deepnesss of the Earth. The taking character in this expedition is a fifty-year-old German professor named Hardwigg. He is an uncle to the storyteller, Henry ( Harry ) , a simple Englishman. The other adult male is Hans, a calm Icelandic usher. Professor Hardwigg finds a piece of parchment that written in Runic in a book. Harry finds out before his uncle that it says there is a manner to acquire into the centre of the Earth through a mountain ( Mt. Sneffels ) in Iceland. Harry is loath to state his uncle the message because he is afraid his uncle will really desire to see the centre of the Earth. He was right because the professor wanted to research every bit shortly as possible. We will write a custom essay sample on A Journey To The Center Of The or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page They head off to Iceland, and, along the manner, receive Hans as their usher. The journey to the mountain itself takes a piece. They reach the entryway to the centre, and from at that place, they head indoors. Once in the dark mazes, they descend ( this goes on for yearss ) . The three work forces so face troubles: thirst, visible radiation, acquiring lost, hurts, and weariness, were among them. They make many finds. They find that there? s a sea, with fish and sea monsters. They find woods, elephantine mushrooms, animate beings that look like dinosaurs, and even what seems to be elephantine human existences. The thought of composing this narrative came from a scientist who explored the crater of a certain mountain. Verne got the thought that maybe it would be possible to fall even further into the Earth. Many of Verne? s? phantasy? narratives have come true in the old ages following his decease in the twelvemonth 1905. A Journey to the Center of the Earth is farthest from world. Even with the engineering we have today, it would be impossible for one to fall into the Earth. For one thing, we know now t hat the Earth can? t be hollow because of utmost force per unit areas and temperatures. Peoples became interested in Verne? s narratives during his clip because though they were unrealistic, they were excessively interesting and entertaining to go through up. Some people even believed he had traveled to the many topographic points that he wrote of. While look intoing into a hotel one time, the adult female told him to rest good in the room because he must be tired from his many escapades. She likely thought this because Verne uses facts of scientific discipline so good the narrative can look as if it were really the existent thing. Verne? s Hagiographas about pigboats, infinite travel, choppers were prognostications of the hereafter. It is a enigma how he came up with such thoughts for wondrous told escapades. Verne grew up when steam engines were altering the universe. He was the first author to proclaim that scientific find could motivate singular narratives. I found A Journey to the Center of the Earth thoughtful and mind-boggling at the same clip. The finds they find are genuinely incredible: Sea monsters, a sea, giants, woods and elephantine mushrooms. These are certainly non-existent because nil like them could populate in such fortunes. The characters in this narrative must hold besides been highly strong and determined, since they? re able to populate for so long resistance in darkness ( slightly ) . The beginning of the narrative is rather slow ; they take a long clip to get down falling into the Earth. Once you get into the narrative, its quite easy to happen yourself in the thick of the channels of granite. A Journey to the Center of the Earth is a wondrous good written book. The really thought of a individual being able to go into the Earth is singular in itself. To set seas and animals into the narrative is exceeding. Jules Verne is such a great author, he makes this escapade seem as if it really happened ; as if it weren? T merely some phantasy, but an undeniable being.

Experimental0. 100 g of powdery impure benzoic acid. 1 little piece of boiling bit. and 2 milliliter of distilled H2O were added severally into a vial. While twirling the mixture invariably. it was so heated to boiling until the benzoic acid had dissolved wholly in the H2O. The solution was so cooled by adding a few beads of distilled H2O. A pinch of activated C was added after. Then. the mixture was heated to boiling for a 2nd clip for a few proceedingss until the volume of the mixture had decreased by about 1 milliliters. The hot mixture was so instantly poured into a 5mL disposable syringe ( without the acerate leaf ) with a cotton stopper indoors at the underside of the syringe tubing to move as a filter. The Piston of the syringe was so pressed to coerce the liquid through the filter. roll uping the filtrate into another phial. The hot concentrated solution or filtrate was so cooled to room temperature before sealing the vial and slow-cooling it in an ice bath. The crystals yielded were collected in a pre-weighed filter paper on a 50 milliliter beaker ( as an jury-rigged filter paper support ) . Small increases of ice-cold H2O were added to rinse the phial to acquire the staying crystals. The filter paper incorporating the gathered crystals was so carefully taken out from the filter system. so was folded with the crystals inside. and so pressed in between folded tissue paper to squash out extra H2O. After leting the filter paper and crystals to dry up wholly. the filter paper with the crystals was weighed. The weight of the filter paper entirely was subtracted from the obtained weight to acquire the weight of the yielded crystals. Percent recovery was computed for by spliting the weight of the yielded crystals by the weight of the impure benzoic acid. V. ResultsFrom the 0. 100 g of the impure sample of benzoic acid. 0. 030 g of pure benzoic crystals was yielded. holding a percent recovery of 30 % . VI. DiscussionThe chemical equation for the reaction of benzoic acid with H2O is as follows: C6H5COOH ( aq ) + H2O ( cubic decimeter ) C6H5COO- ( aq ) + H3O+ ( aq ) .It is a reversible reaction allows the dissolved benzoic acid to recrystallize or travel back to its solid signifier as a purer compound.

What advantages does H2O hold as a crystallisation dissolver? * non-flammable* safe and non-toxic* used for a broad scope of temperatures* high heat capacity and can fade out different substances * polar. therefore. it can fade out substances. particularly polar 1s. easy. 4. Solubility of benzoic acid in H2O: 0. 21g/ 100mL H2O at 10oC ; 0. 27g/100mL at 18oC ; 2. 75g/ 100mL at 80oC ; 6. 80g/ 100mL at 95oC. Two pupils crystallized 10 g samples of benzoic acid from H2O. the first dissolution benzoic acid at 80oC and filtrating at 10oC. the 2nd fade outing the acid at 95oC and filtrating at 18oC. Calculate the measure of H2O each pupil was required to utilize and the maximal recovery of benzoic acid possible in each instance.

A Solid ( X ) is soluble in H2O to the extent of 1g per 100g of H2O at room temperature and 10g per 100g of H2O at the boiling point. a. How would you sublimate X from a mixture of 10g of Ten with 0. 1g of dross Y. which is wholly indissoluble in H2O. and 1g of dross Z. holding the same solubility features in H2O as X? Separating Yttrium 1. Dissolve the mixture in 100g H2O and furuncle to 100?C. Everything should fade out except for Y. 2. Cool mixture to room temperature3. Filter. This will divide dross Y from X and dross Z. Separating Z1. Add H2O up to 100mL to the filtrate.2. Heat to boiling ( 100oC )3. Slowly cool to room temp4. Filter the mixture. The filter paper residue= pure X crystals. *Formation of Z is undistinguished because it is merely 1g and has a different crystal construction than X. excepting Z from Xââ¬â¢s crystallisation. 90 % or 9g of Ten will be obtained90 % or 9g of Ten will be obtainedB. How much pure Ten could be obtained after one recrystallization from H2O? 10g of X ââ¬â 1g X dissolved ten 100 % =10 g of X *Solubilities of different solutes are independent of each other. therefore. 1 g of solutes X and Z would fade out at room temperature. c. How much pure Ten could be obtained after one recrystallization from a mixture of 10g of Ten with 9g of Z? * A = 1000g H2O to fade out 10g X @ room temp.A = 1000g H2O to fade out 10g X @ room temp.Ten and Z must be dissolved foremost. Solubilities of X and Z are independent of each other. Solid X. being the larger sum. is used as footing. 10g of X = 1g of TenA g H2O 100g H2O* B= 900g H2O to fade out 9g Z @ room temp.B= 900g H2O to fade out 9g Z @ room temp.Water must so be boiled until 900g of H2O is left to guarantee dross Z wonââ¬â¢t dissolve and crystallise with X under room temperature. 9g of Z = 1g of OmegaB g H2O 100g H2O* C= 9g of X dissolved in900g H2O @ room temp. C= 9g of X dissolved in900g H2O @ room temp. Slowly cool the solution to organize X crystals.C g of X = 1g of Ten900g H2O 100g H2O 1 g of X crystallized1 g of X crystallized 10g X- 9g Ten dissolved= d. Based on the consequence obtained. what is suggested about the usage of crystallisation as a purification technique? Using crystallisation to divide and sublimate solid substances is non so efficient because of its heavy dependance on the substanceââ¬â¢s solubility. doing it hard to divide substances of the same solubility and of important sums. VIII. Decision Recrystallization. although a common purification technique for its simpleness and utility. is non such an efficient method because it CANââ¬â¢T: * sublimate non-solids* separate compounds whose constituents ( the chief constituent and dross ) have the same solubility due to recrystallizationââ¬â¢s heavy dependance on solubility. particularly when both constituents exist in important sums * wholly sublimate the end-product IX.

TASTE OF SALT essays
TASTE OF SALT essays This story takes place in the slums of Haiti. In a hospital bed, lays Djo, beaten and hardly alive. Djo is an innocent victim of a political firebombing. The Macoutes, or the bad guys, pour gasoline in and on the camps of the followers of Aristide. They rob and slaughter the members of the camps. He is also a vital member of Father Jean Bertrand Aristides. Father Aristide, or as the local Haitians call him, Titid, sends Jeremie to Djo. She has a tape recorder with her. Jeremie is there to listen and to tape Djos story as from a little child to present date. Djo tells her of how he was raised in Cit Soleil, a very poor and large part of Port-au-Prince. Djo lived in a one room house witch was a stall for a motor car, or a garage. He lives with his mother, father, two sisters and two brothers, also his cousin Lally. All of the children sleep in one bed together and the mother and father have a bed of their own. His family is very poor, just like the rest of the citizens of Port-au-Prince. During the story, Djo finds Aristide. Aristide, or as Djo calls him, Titid, is the first democratically elected president of Haiti. He is a Salesian priest whose first and continuing ministry has been among the poor of Port-au-Prince. Father Aristide wants Haiti to become better. He wants people to live decent lives, with food everyday, and clean water to drink. People like Djo and Jeremie are the one who try to overthrow military dictatorship in Haiti. I think that Djo is a very determined man. He was poor all of life and didnt just feel bad for himself. He rised above it to actually do something about the terrible case of poverty in his country. Djo almost gave his life to overthrow the militia government. Everyone who heard his story, because it was amazingly full of courage loved him. Salt tastes rancid and bitter. So, Francis Temple relates the taste of salt with the lives of the Haitians. In other words, &q...
