Electrophoresis Machine

Gel electrophoresis is a laboratory procedure used to separate biological molecules with an electrical current. In this lesson, we’ll review how agarose gel electrophoresis works and introduce the equipment necessary to perform an electrophoresis experiment. Separation of DNA molecules of different sizes can be achieved by using an agarose gel. Recall that agarose is a polysaccharide that can be used to form a gel to separate molecules based on size. Because of the gelatin-like nature of agarose, a solution of agarose can be heated and cooled to form a gel in a casting tray. Think of casting the agarose gel like pouring hot gelatin into a mold. The hot agarose liquid is poured into a casting tray. Once the mixture…

Riordan Amended IT Budget

Amended Riordan Manufacturing IT Budget The executive board for Riordan has tasked Information Technology with reducing their overall budget by two percent, while providing an increase of four percent to hardware line item, software line item, and outside IT support services. There are many lines within the budget that can be cut immediately to provide the necessary budget cuts, but it is important to make sure that none of the services being provided to staff will suffer with the adjustment to the budget. This paper will discuss the current budget, the increased made to the requested line items and the overall budget decrease. The paper will also justify the changes made to the budget. CURRENT BUDGET Riordan’s current IT budget…

Review Sheet Results

1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. Your answer: Because outside a typical cell, the concentration of K+ is about 5mM and the concentration of Na+ is about 150 mM. When you increase the concentration of K+ from 5 to 25 mM and reduce concentration of Na+ from 150 to 130 mM, the outside has more concentration of K+. The membrane is permeable to a particular ion, that ion will diffuse down its concentration gradient from a region of higher concentration to a region of lower concentration. 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative value. How well…

Dissolved Oxygen

Oxygen in Liquids (DISSOLVED OXYGEN) Dissolved Oxygen – the amount of dissolved oxygen in a body of water as an indication of the degree of the health of water and its ability to support a balanced aquatic ecosystem. Oxygen – is a clear, colorless, odorless, and tasteless gas that dissolves in water. Small but important amounts of it are dissolved in water. OXYGEN: Aquatic Life Depends on it Plants and Animals depend on dissolved oxygen for survival. Lack of dissolved oxygen can cause aquatic animals to leave quickly they are or face death. Factors Affecting Oxygen Levels Temperature Rate of Photosynthesis Degree of Light Penetration (turbidity & water depth) Degree of Water Turbulence or Wave action The amount of oxygen…

Texas Instruments

After thoroughly analyzing the information available on TI, I have identified three critical issues that need immediate attention. These include the capacity crunch in meeting forecasts, expectation to reduce the cost per watch, and a lack of efficiency of the workers. In order to tackle these issues, I recommend reducing the cycle time, increasing capacity in subsequent years, and increasing worker efficiency. These recommendations will enable you to achieve the targets and put TI on the path of success ISSUES Capacity crunch: As per the forecasts for world market demand for electronic watches, the current capacity at TI is insufficient. In order to cater to this increasing demand, the capacity needs to be enhanced. The technological advancements have prompted the…

Microelectronic Pill

1. ABSTRACT A “Microelectronic pill” is a basically a multichannel sensor used for remote biomedical measurements using micro technology. This has been developed for the internal study and detection of diseases and abnormalities in the gastrointestinal (GI) tract where restricted access prevents the use of traditional endoscope. The measurement parameters for detection include real – time remote recording of temperature, pH, conductivity and dissolved oxygen in the GI tract. This paper deals with the design of the “Microelectronic pill” which mainly consists of an outer biocompatible capsule encasing 4–channel micro sensors, a control chip, a discrete component radio transmitter and 2 silver oxide cells. | Our Body is a sensitive system. Many times even doctors arenâ„¢t able to interpret the…
