secretion system, which acts as a biological syringe to translocate toxic effector proteins to the target human cell. The effector proteins can alter the metabolism of the target cell, making it easier for intracellular motility of Shigella bacteria inside the host cell. Unlike many other pathogenic bacteria, S. sonnei does not use flagella for its chemotoxicity and tissue invasion. Without flagella, S. sonnei can often escape the human immune system that usually mediates the innate and adaptive immunity

interconnected with other neurons die increasing the efficiency of the nervous system. In other words, if the baby’s experiences do not stimulate nerve connections the unused neurons are eliminated by synaptic pruning. The pruning down of the unnecessary neurons allow for the established neurons to build elaborated communication with other networks. This is contrary to other aspects of growth because the nervous system continues more effectively through the loss of

Sensory Adaptation American Intercontinental University Sensory Adaptation The three experiments I chose to conduct were Experiment 1, Experiment 2, and Experiment 4. All of the experiments were interesting in their own way. Each experiment had a different outcome but all support adaptation within the experiment. Beginning experiment 1 I purchased a small piece of very coarse sandpaper at the local hardware store. I began by rubbing my index fingers across the sandpaper a few times

engineering, the power flow study, also known as load-flow study, is an important tool involving numerical analysis applied to a power system. A power flow study usually uses simplified notation such as a one-line diagram and per-unit system, and focuses on various forms of AC power (i.e.: voltages, voltage angles, real power and reactive power). It analyzes the power systems in normal steady-state operation. A number of software implementations of power flow studies exist. In addition to a power flow

Lecture 2 questions (it began lecture1) 1. What is HRIS (human resource information system)? It is a computerized system that provides current and accurate data for purposes of control and decision making. It not just hardware-software, includes people, forms, policies, procedures and data. The purpose is to provide service, and it has many users, such as Strategic, Tactical and Operational decisions. HRIS has many benefits; for example. * Store and retrieve of large quantities of

restoring the body in several ways; firstly Slow Wave Sleep (SWS) is said to be the stage of sleep that releases the growth hormone. This hormone is functional for renewing proteins and involved in protein synthesis, and also involved in the immune system in restoring antibodies. This idea is supported by Sassin et al who looked at individuals who "reversed" their sleep cycle, so they were asleep during the day and awake at night, and the growth hormone was still released during sleep, supporting the

Introduction: Neuropsychologist have proven that before birth one’s brain eliminates around half of its neurons (Toga & Mazziotta, 2000). This concept is called exuberance followed by regression (Beauregard et al. 2001; Ochsner et al., 2002). Initially, one’s brain will developed too many neurons and then prune those that are not used during its organized period. The brains organizational period begins before birth and continues into adulthood. During the brains organizational period, the structure
