Transcript: Free Read PowerPoint Project Judith Rumelt, better known by her pen name Cassandra Clare, is an American author of young adult fiction. Main Characters Summary Prominent literary item Will Herondale-Will has dark hair and ocean blue eyes. Will is rude and cruel because he believes everyone that loves him will die. He believes this because a demon put a 'curse' on him. Tessa Gray- Tessa has blonde hair and grey eyes. She is very witty and enjoys literature. Recommendation of book Setting Jem Carstairs-Jem has silver hair and eyes, due to the drug he was tortured with before his family was killed. He plays the violin and is very kind, caring, and lovable. The most unique thing in Clockwork Angel is that there are supernatural occurrences such as demons, shape shifters, witches, vampires, and werewolves, etc. I definitely recommend Clockwork Angel by Cassandra Clare. I recommend this book because it uses great figurative language, such as "The machine walked like a man." Also, "There was a boy standing in front of her. He couldn´t have been much older than she was-seventeen or possibly eighteen. He was dressed in what looked like workman´s clothes-a frayed black jacket, trousers, and tough-looking boots. He wore no waistcoat, and thick leather straps crisscrossed his waist and chest. Attached to the straps were weapons-daggers and folding knives and things that looked like blades of ice. In His left hand-slim and long fingered-was bleeding where she had gashed the back of it with her pitcher. But that wasn´t what made her stare. He had the most beautiful face she had ever seen. Tangled black hair and eyes like blue glass. Elegant cheekbones,and long, thick lashes. He looked like every fictional hero she´d ever conjured up in her head. Tessa Gray goes to London to live with her brother. When she arrives Tessa is captured by twin sisters dubbed 'the Dark Sisters'. She was tortured and forced to use her gift of shape shifting for evil until Will Herondale rescues her. He then takes her to the institute, a place for shadowhunters to be cared for. Tessa meets the residents of the institute, Charlotte Branwell, the head of the institute, Henry Branwell, Charlotte's husband and inventor of a many great inventions, Jessamine Lovelace, girly and against all things shadowhunter, Jem Carstairs, a kind but very ill shadowhunter. Presentation Themes Clockwork Angel by Cassandra Clare Most unique thing in the book Presentation by Canaan Hall Clockwork Angel takes place in the institute, and the Dark Sister's home. The institute is an old church with very many rooms for passing visitors. The Dark Sister's house is large but sparsly furnished, in Tessa's room there is a bed with restraints, a mirror, and a nightstand with a few books. The themes for Clockwork angel are; you always need friends that you can trust, don't judge someone by their looks you don't know what they are going through, and even someone you wouldn't expect could be the hero. Cassandra Clare One prominent literary item in the book is personification. Personification is used throughout Clockwork Angel, such as "The machine walked like a man." Another example is, "The door creaked with a noise that sounded like a scream."
Transcript: A. Explain Technique for Taking Electrocardiogram B. Explain Correct placement of the electrodes C. Explain The normal Electrocardiogram D. Discuss the Mean Electrical Axis deviation Normal Impulse Conduction Impulse Conduction & the ECG Step 4: Determine PR interval An electrocardiogram is a recording of the electrical activity within the heart that is obtained by placing various electrodes on the skin surface. From this painless, quick and inexpensive test, doctors are able to evaluate a person's heart rate and rhythm and to detect if something is wrong. Premature Atrial Contractions (PACs) Atrial Flutter Normal: 0.04 - 0.12 seconds. (1 - 3 boxes) Interpretation? Option 2 Find a R wave that lands on a bold line. Count the # of large boxes to the next R wave. If the second R wave is 1 large box away the rate is 300, 2 boxes - 150, 3 boxes - 100, 4 boxes - 75, etc. (cont) Ventricular cells can: fire occasionally from 1 or more foci fire continuously from multiple foci fire continuously due to a looping re-entrant circuit PVCs The QRS axis is determined by overlying a circle, in the frontal plane. By convention Step 3: Assess the P waves Ventricular Cell Problems QRS equivocal (R = Q+S) Atrial Cell Problems Atrial Cell Problems ELECTRO-CARDIOGRAM Rate Rhythm Axis Intervals Hypertrophy Infarct Mean of Axis Deviation Ten electrodes are used for a 12-lead ECG. The electrodes usually consist of a conducting gel, embedded in the middle of a self-adhesive pad onto which cables clip. Sometimes the gel also forms the adhesive. They are labeled and placed on the patient's body as follows Arrhythmias can arise from problems in the: Sinus node Atrial cells AV junction Ventricular cells Step 1: Calculate rate. Step 2: Determine regularity. Step 3: Assess the P waves. Step 4: Determine PR interval. Step 5: Determine QRS duration. Option 2 (cont) Memorize the sequence: 300 - 150 - 100 - 75 - 60 - 50 Interpretation? NSR Parameters 9 x 10 = 90 bpm Step 1: Calculate Rate Sinus Bradycardia Sinus Tachycardia Electrocardiograph The SA Node can: fire too slow fire too fast Normal: 0.12 - 0.20 seconds. (3 - 5 boxes) Interpretation? Atrial cells can also: • fire continuously from multiple foci or fire continuously due to multiple micro re-entrant “wavelets” Sinoatrial node AV node Bundle of His Bundle Branches Purkinje fibers Correct Placement of Electrodes The AV junction can: fire continuously due to a looping re-entrant circuit block impulses coming from the SA Node Rate Rhythm Axis Intervals Hypertrophy Infarct The “PQRST” T wave - Ventricular repolarization Approx. 1 box less than 100 = 95 bpm Atrial depolarization + delay in AV junction (AV node/Bundle of His) (delay allows time for the atria to contract before the ventricles contract) Step 1: Calculate Rate SA Node Problems The ECG Paper (cont) EKG leads are attached to the body while the patient lies flat on a bed or table. Leads are attached to each extremity (four total) and to six pre-defined positions on the front of the chest. Sinoatrial node AV node Bundle of His Bundle Branches Purkinje fibers Paroxysmal Supraventricular Tachycardia AV Junctional Blocks Normal Sinus Rhythm (NSR) In some instances, men may require the shaving of a small amount of chest hair to obtain optimal contact between the leads and the skin. Abnormal Signal moves slowly through the ventricles Ventricular Conduction Rhythm Analysis Rate 90-95 bpm Regularity regular P waves normal PR interval 0.12 s QRS duration 0.08 s Interpretation? Normal P waves with 1 P wave for every QRS R wave Step 2: Determine regularity Option 1 Count the # of R waves in a 6 second rhythm strip, then multiply by 10. Reminder: all rhythm strips in the Modules are 6 seconds in length. Interpretation? The leads are attached by small suction cups, Velcro straps, or by small adhesive patches attached loosely to the skin. The test takes about five minutes and is painless. Technique for Taking Electrocardiogram Regular Look at the R-R distances (using a caliper or markings on a pen or paper). Regular (are they equidistant apart)? Occasionally irregular? Regularly irregular? Irregularly irregular? Interpretation? A QRS axis that falls between +90o and +150o is abnormal and called right axis deviation Step 5: QRS duration The QRS axis is determined by overlying a circle, in the frontal plane. By convention Pacemakers of the Heart Atrial Fibrillation Atrial Fibrillation Arrhythmia Formation Teaching Moment The ECG Paper When an impulse originates in a ventricle, conduction through the ventricles will be inefficient and the QRS will be wide and bizarre. We can quickly determine whether the QRS axis is normal by looking at leads I and II. Sinus Tachycardia may be an appropriate response to stress. PVCs Rate Rhythm Axis Intervals Hypertrophy Infarct Etiology: One or more ventricular cells are depolarizing and the impulses are abnormally conducting through the ventricles.

The PL emission of ZnS-graphene decreased compared to the pure ZnS due to the presence of graphene the PL emission of the ZnO-ZnS core-shell nanostructure decreased due to the presense of ZnS shell and formation of type-II band alignment structure in the hetero-interface which is beneficial for solar cell devices. The presence of rGO in ZnS-rGO composite gives significant improvement in the degradation of methylene blue under visible light irradiation compared to pure ZnS, due to the increased adsorption of the dye, decrease in the band gap and stepwise structure of the energy levels in the composite. The presence of graphene and PPy in the GZP turnary composite lead to higher photocurrent response due to the creation of an interfacial separation between the graphene and the PPy by ZnS nanoparticles, which act as a bridge, and due to enhanced charge transport by graphene.
