This device will be developed to construct a reliable protection system. The study compares the difference of laser light activated alarm to the other commercial detector. The device will be developed to use a LASER Light Activated Alarm which has detecting diode or the photocell‚ which turns the device on when the photocell

to be activated. This happens through a process called antigen presentation. When the receptor of a helper T cell recognizes the antigen‚ the T cell is activated. Once activated‚ helper T cells start to divide and to produce proteins that activate B and T cells as well as other immune cells. Killer T cells specialise in attacking infected cells of the body and do this by directly attacking other cells carrying foreign or abnormal antigens on their surfaces. Once they have been activated by a helper

Secondary water treatment method involves the removal of fine and dissolved wastes that are organic by the use of a biological process of treating water. The common approaches to biological water treatment process are the activated sludge and trickling filter. Activated sludge through the aeration of the mixture of microorganisms‚ which are also referred to as biological sludge‚ and wastewater. The microorganisms are subjected under an environment that facilitates their growth (Neary‚ 2009).The

Chapter 16-Lymphatic System & Immunity 1. Explain the functions of the lymphatic system. The lymphatic system functions to balance fluid‚ lipid absorption (via lacteals=lymph capillaries) and defense. It removes toxins/pathogens‚ fight infections and transports excess fluid in the interstitial spaces and returns it to the blood stream. Lacteals absorb digested fats from small intestines and transports it to venous circulation. 2. Trace the general pathway of lymph from the interstitial

Briefly describe how the following cells become activated in the adaptive immune response. A. B Cells (T-Dependent Antigen) : Helper T cells B. B Cells (T-Independent Antigen) : B Cell directly binds to antigen C. Helper T Cells: Dendritic Cells D. Cytotoxic T Cells: Dendritic Cells E. Macrophages:

Construction Stage 1‚ both piers are activated together with the pier-tables. The boundary conditions for the base of the piers as restrained in 6 degrees of freedom and rigid elastic links for the connection between pier and girder is defined. The loads applied in this stage are due the form travelers for the segments 1 at the first day of the stage‚ and the weight of the wet concrete for the segments 1 at the 4th day. In Construction Stage 2‚ segments 1 are activated. No new boundary conditions are

to enter then the white blood cells will become activated and will attack the area of infection. They become activated when the dendritic cell engulfs neutrophils which contain the remains of pathogens that they have killed. The dendritic cells travel in lymph to the lymph nodes where it is chemically directed to co-operate with T helper cells that have receptors that are able to recognise proteins from

In this lab‚ we are measuring the EMG amp (mV)‚ or electrical activity‚ from action potentials produced from muscle contractions in order to gain an indication of the number of active motor units used in the contraction. This is done by adding more load to the muscle or force. There is examining of the EMG amp produced from a twitch at varying levels of muscle force and EMG amp from muscles when more load is placed on them. During the experiment‚ we set up the equipment‚ electrodes and software

ACTIVATED SLUDGE DIAGRAM DEFINITION: Activated sludge is a term that refers to suspended aerobic consisting of flocs of active bacteria‚ which are mixed with wastewater. The bacteria consume and remove aerobically biodegradable organic substances from screened; or screened and presettled wastewater in an aerated tank. The organic pollutants in the wastewater are used by the bacteria to grow and transform it to energy‚ water‚ CO2 and new cell material. Activated sludge systems are suspended-growth
