De Leon, Carisse Alliyah Ms. Ellis AVID Health Survey P6 11/17/17 Bromo Dragonfly Research Paper The Bromo Dragonfly--also known as Bromo-benzodifuranyl-isopropylamine, 3C-Bromo-Dragonfly, or DOB-Dragonfly-- is an uncommon drug, mainly known in the United Kingdom and in the United States. Although it is not really known around the world, many countries/states have put restrictions on the use of this drug due to its potential of being abused. While the drug does not have many long term effects, if it is not used in moderation, it can be very dangerous and may even result in death.
Introduction/Purpose : In this experiment crickets are going to be drugged with two amounts of caffeine. Crickets are omnivores and scavengers that feed on organic materials, as well as decaying plant material, fungi, and seedling plants. They are usually medium-sized to large insects, and known to be relatives and/or look alike to a grasshopper. Crickets can live for a year or more, but usually can't survive more than one winter.
An electrocardiogram records the electrical activity on the surface of the heart. One method of acquiring an electrocardiogram is by the usage of a handheld single channel ECG machine. Figure 1 displays the results of my single electrocardiogram result. From this figure, one can calculate the heart rate by dividing the number of intervals over the time and multiplying by 60 in order to get the heart rate in beats per minute (BPM). Based on the electrocardiogram, there were 7 intervals in a time span of 6 seconds.
Metabolism The daphnia’s main composition consists of a midgut, hindgut and an esophagus running from its head down its body, using one compound eye as an aid in swimming. The position of the heart is right above where the location of eggs in the females back. The water flea’s usual food source is
If the population of elapsed time intervals until an event occurs is assumed to follow an exponential distribution, implying a constant hazard rate throughout every observation subwindow, the maximum likelihood estimate of that hazard rate is 0.2361, with a standard error of 0.013790. The assumption of an exponential distribution with a constant hazard rate produces an EXTREMELY GOOD fit with the observed data. The analogue of an unadjusted coefficient of determination (R-squared) would be 0.9974. An attempt was made to fit a Weibull distribution to the same data.
Pediatric interventional cardiology is a passion and a dream which I hope one day to realize. During my first pediatric residency training, I realized the depth of my interest in cardiology. I found pleasure and interest in all the pediatric cardiology rotations; however, cardiac catheterization, despite the limited sophistication with which it was performed, captivated me. As there were no training opportunities available back home and few interventional procedures can be done due to lack of experience in congenital interventional cardiology. Therefore, I decided to pursue a second pediatric residency training in the USA to allow me the opportunity for further training in pediatric cardiology and eventually congenital cardiac intervention.
The graph displays a negatively skewed trend, which suggests that the hypothesis was not supported. This is because the greatest percentage of caffeine (100%) did not result in the greatest reaction time, as predicted. The subjects who drank a 50% caffeinated beverage had the fastest reaction rate, taking an average of 0.39478 seconds to react. Comparatively, the subjects that drank the 100% caffeinated beverage had a slower average reaction time of 0.45917 seconds, taking longer to react. The subjects who were not exposed to any caffeine (0%) had a reaction time of 0.47293 seconds.
NEW YORK (WENY) - You often hear you have to guard your heart, but what if your life depended on it. For one local women battling heart disease, her heart beats are numbered. For the past 15 years, Donna Dacey's life has been filled with doctor's appointments, a cabinet full of medication and wondering when she's going to hear the dreaded words "you need a heart transplant." "After a lot of testing they discovered I had dilated cardiomyopathy and congestive heart failure.
The reason for this is that equines are particularly sensitive to atropine and related tropane alkaloids. Being hindgut fermenters, the alkaloids are absorbed as the contaminated feed passes through the stomach. The mechanism of action of Datura plant after ingestion is that muscarinic receptor antagonists compete with acetylcholine (ACh) for a common binding site on the muscarinic receptors and thus block the action of ACh at muscarinic neuro effector sites on smooth and cardiac muscle, gland cells, in peripheral ganglia and in the central nervous system (CNS). In general they cause little blockade at nicotinic receptor sites (Brown and Taylor, 2001). Datura intoxication produce hyperthermia, tachycardia, painful photophobia and the presence of pronounced amnesia have been reported (Freye and Enno, 2009).
A lot of people love sugary foods and drinks. This experiment can be applied to the real world because it shows how something so delicious can affect our overall health exceedingly. Since sugar affects our heart rate and blood pressure in different ways in many peculiar people, there are contrasting affects that can happen to people. For example, sugar can make the human body 's pulse and blood pressure increase or decrease. Both ways can be risky for your health.
It beats for about 60 times per minute as compared to human heart which beats for about 80 times per minute. A manatees heart is seen to beat slow as 30 heartbeats per minute on longer dives. Whereas in dugongs it has double ventricular apex of heart. The unusual feature of the sirenian heart is that the heart has double subvalvular conus and dorsal left atrium.
HEART COMPLICATION – Caffeine and other ingredients in the energy drinks can increase the heart rate and blood pressure. Caffeine is the ingredient which can influence the heart beat due to the liberate of calcium from the heart cells. Caffeine and other ingredients in the energy drink also increase the blood pressure which can damage the normal balance of salts in the body. These complications can cause many health problems such as arrhythmia, cardiac arrest, hypertension, coronary heart failure, etc. Highly caffeinated energy drinks and energy shots may enhance sports performance and keep someone alert and attentive but the risk of getting too much of caffeine intake can endanger the heart at any age.
But many athletes, then athletes in the broadest spectrum of disciplines, as well as students who are learning hard for exams, used pure synthetic caffeine in the form of pills. In whatever form that takes, caffeine eventually decompose and stimulates the release of fat. It is believed that caffeine stimulisee release of excitatory hormones epinephrine and neorepinefrina from the adrenal gland, and also stimulates the brain to release dopamine; thus stimulates the release of fat and increases energy, stamina and mental clarity. This naturally raises us and "pump" we metabolism, a posledeca is greater calorie burn. Contrary to what would you say to some experts, these effects can be obtained without the unwanted side-effects.
Talea Claassens gr11 Life Sciences Title: The effect of Red Bull (caffeine) vs taking nothing on your heart-rate and speed during the course of a 50m swim. Research Question: Will Red Bull have a positive result on your heart-rate and swimming speed compared to the results of not taking the red bull. Hypothesis: The Red Bull will have the best result on the heart-rate and swimming speed (increasing your speed) followed no supplements.
Research on the use of toxicants involves efficiency, delivery systems and by-kill (Marks et al. 2006). Moseby & Hill (2011) undertook a large scale baiting trial with 1080, they found a major decline in cat activity after the first baiting event however. 1080 is not species-specific, Denny (2001) calculated that, at least 61 native vertebrate species were known to have consumed 1080 poison bait, and 24 of these natives were known to have been killed by 1080 poison. Eason et al. (2010) explored the use of Para aminopropiophenone, a poison used as an alternative to others, it’s said to provide gradual loss of consciousness and death without the pain and suffering that other compounds can
