Intestinal ischemia following aortic reconstruction is a severe complication with 1% mortality. Although the manifestations of colon ischemia become obvious in the early postoperative course. In the case presented here‚ sigmoid rupture and small and large intestine communication was revealed three months following repair of the abdominal aorta. A 71-year old man‚ following open repair of an abdominal aortic aneurysm went home on the 5th postoperative day. Three months later was admitted to the

This portfolio is an investigation into how the median Body Mass Index of a girl will change as she ages. Body Mass Index (BMI) is a comparison between a person’s height (in meters) and weight (in kilograms) in order to determine whether one is overweight or underweight based on their height. The goal of this portfolio is to prove of disprove how BMI as a function of Age (years) for girls living in the USA in 2000 can be modeled using one or more mathematical equations. This data can be used for

Does the seal and killer whale relationship represent a sigmoid or peak phenomenon? Please provide supporting details. 6.What are the limitations of the population dynamics lab? Is the lab activity a realistic representation of an arctic marine ecosystem? Note: Please

Purpose The digestive system prepares food for use by hundreds of millions of body cells. Food when eaten cannot reach cells (because it cannot pass through the intestinal walls to the bloodstream and‚ if it could would not be in a useful chemical state. The gut modifies food physically and chemically and disposes of unusable waste. Physical and chemical modification (digestion) depends on exocrine and endocrine secretions and controlled movement of food through the digestive tract. Mouth Mouth

Purpose: Analyze graphs to determine the carrying capacity of two marine species. Explain how predation‚ birth‚ and death rates impact population size and carrying capacity of marine populations. Describe how biotic and abiotic factors influence the carrying capacity of marine populations. Research: Prey initial size- 25 Prey birth rate- 0.05 Predator initial size- 25 Predator death rate- 0.05 Capture efficiency- 0.005 Hypothesis: If the starting population of the prey is higher than

This error is needed actually ErrorB = OutputB (1-OutputB)(TargetB-OutputB) (5.19) Output (1- Output) is necessary in the equation because of the Sigmoid Function (Target – Output) is needed if threshold activation function is used. 3. Change the weight. Let W+AB be the new (trained) weight and WAB being the initial weights. Notice that it is the output of the connecting neuron (neuron A). Update
