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.

Electro Cardiogram

Transcript: Timeline Rami Kenawi / Electrocardiogram 1982 The First Electrocardiogram With physicians starting to understand how electricity flows through the body, Dr. Augustus D Waller discovered the first electrocardiogram. In 1877, Augustus Waller traced the human heart by using a mercury capillary electrometer and a toy train at St. Mary’s Hospital, London. The tracing revealed only 2 deflections which he labeled V1 and V2 to indicate ventricular events. (Litfl, 2022) 1901 String Galvanometer In 1901, Einthoven invents the Saitengalvanometer (string galvanometer) using a fine quartz string coated in silver (rather than the wire coated string of Deprez and d’Arsonval). He presented cases of atrial and ventricular hypertrophy; ventricular bigeminy, ventricular premature beats (Litfl, 2022) 1931 Precordial Lead In 1931, Charles C. Wolferth and Francis Clark Wood introduce the precordial lead (lead IV) in clinical diagnostic cardiology. This allowed the electrocardiogram to become more sensitive to detect electric forces eminating from the heart. (Litfl, 2022) 1949 Electrocardiography In 1949, Norman "Jeff" Holter produced the first ECG radio transmitter with batteries weighed more than 38 kg. The first broadcast of a radioelectrocardiogram was then relayed in history. (Litfl, 2022) 1978 Implantable Electrocardiogram In 1978, Alois Langer, Marlin Heilman, Morton Mower and Mieczyslaw Mirowski patented a “Circuit for monitoring a heart and for effecting cardioversion of a needy heart.” The start of the development of the implantable cardiac defibrillator. [A chronically implanted system for automatic defibrillation in active conscious dogs. This became an experimental model for treatment of sudden death from ventricular fibrillation.(Litfl, 2022) 2018 Apple Smart Watch In 2018, Apple begings to improve their heart pulse detector by studying whether a wearable technology can identify irregular heart rhythms suggestive of atrial fibrillation. (Litfl, 2022) 2021 Kardia In 2021, Kardia a tech company, develops a credit card for measuring heart ryhtm and data while creating a new mobile device as well. Users would be able to detect the most common arrhythmias. (Kardia, 2021) Citations Cadogan, M. (2022, July 27). History of the electrocardiogram. Life in the Fast Lane • LITFL.

Transcript: Importance of the 3 levels of Govt. It is beneficial for a country to have 3 different levels of government because various different situations and problems can be handled with different levels as each one has its own set of responsibilities and commitments. For example, public transit issues would be handled by the Municipal Government, whereas property and civil rights would fall under the Provincial/Territorial Government, and finally citizenship or insurance would be handled by the Federal Government. Going up every level, the responsibility grows more importance, and with 3 levels of government it is far more easy to organize these responsibilities. General Responsibilities: defense criminal law employment* insurance postal service census* copyrights trade regulation external relations* money and banking transportation* citizenship Indian affairs General Responsibilities: property and civil rights* administration of justice natural resources and the environment* education healthcare* welfare* General Responsibilities: water* sewage* waste collection/management* public transit* land use planning* libraries emergency services* animal control economic development* Caused by: Failure of pumps at Point Lepreau Coolants stopped working because of a power outage caused by a storm which caused malfunctions Lack of maintenance for their back up generators which meant that all systems stopped working Responding to Death Strike The Federal Government would respond by: Employing volunteers to help cleanse the area of nuclear pollutants Ask for assistance with allied countries Assist Municipal governments with transportation issues Execute the Federal Nuclear Emergency Plan (FNEP) Dealing with water leakage issues Municipal Government Reaction The Municipal Government would respond by: closing up their sewage areas to keep radioactive water from entering Doing an emergency evacuation either in the city or even out of it Transporting people out during evacuations Assisting in traffic control emergency shelters Federal Government Reaction The meltdown from the reactor released huge amounts of radiation within the proximity, killing people with these rays. In addition to this, radioactive material was released into the water not only affecting many of the waters from the tsunami in Japan but also it entered the pacific ocean. That harmed the wildlife but also would travel east to the United States and Canada In the case of our disaster, we wouldn’t really be facing a tsunami, but a defective cooling pump that is backing up causing unnecessary harm to the nuclear plant and other damage. Provincial/Territorial Government The Provincial/Territorial Government would respond by: They would help in major scale evacuations. For instance, they may order evacuations provincial wide and get all the southern areas in NB to areas like the northern part of the province Nova Scotia, Ontario, Quebec or even the United States They would aid in traffic control for major roads to make sure the people or buses are evacuating properly They may also need to be there to provide larger shelters They might need to cut schooling during this predicament. Along with the federal government, surrounding provinces may need to bring their environmental policies to their citizens to make sure certain ares wouldn't go outside at the time In addition to the shelters, they might have to provide rations and help the ones who were evacuated with gathering for Health Units along with the Federal government. The Levels of Government Nuclear Breakdown Fukushima Daiichi Nuclear Blast Radius Provincial/Territorial Government Reaction Relief Plan: The aspects of administration involved and required for the relief plan would obviously consist of the International Atomic Energy Agency (IAEA) as stated before to help with dealing with the nuclear waste radiating from the leakage. Also, because of the fact that this is Canada's first ever nuclear disaster, aid and support from allied countries such as Japan would be extremely beneficial as they would provide updated instructions and coordinations from their previous encounters with nuclear disasters. (Fukushima) What are the levels of government? Federal Government INTERNATIONAL ATOMIC ENERGY AGENCY Death Strike; What caused it? Chernobyl Blast Radius Municipal Government Area of Pointe Lepreau and Possible Evacuation Areas Death Strike Havoc Report Sites in and around Point Lepreau that have a potential risk of being exposed to radiation
