Finding the concentration of an unknown sample of copper sulphate using colorimetry. In this task the concentration of an unknown sample of copper sulphate using colorimetry was used to find the concentration. In this investigation copper sulphate was used which is CuSO4.5H20 as a formula. To make a standard solution which was 1M, the same clean equipment was used to make up the standard solution as used to make sodium carbonate. However there was one difference and that was that the hot distilled

Equipment Review The equipment in this study includes a Vertec vertical jump measuring system (Figure 1) and a Bertec force plate (Figure 2). The Vertec vertical jump measuring system measures individuals vertical jump capabilities in inches. The Bertec force plate measures the ground reaction forces in newtons produced when an individual performs a jump and when they land following a jump. The Vertec vertical jump measuring system is constructed out of a steel frame and has horizontal vanes that

Purpose: The purpose of this outline is to act as a guide and accompaniment to the Fetal Fibronectin Power Point as well as an aid for the Case Study learning activity. Objectives: 1. Describe the testing method used to determine the results of the Fetal Fibronectin Cassette. 2. Be aware of the containments that may interfere with the FFN test. 3. Calibrate rapid FFN cassettes when necessary. 4. Identify correct and incorrect specimens and the storage requirements of the specimen. 5. Assess

The SI traceability chain is shown in Fig. 6. The DUTs are calibrated with a current source and voltmeter. The current source is calibrated using the NIST TS CVC [3, 5]. The TS CVC’s feedback resistors are calibrated (in situ) by comparison to NIST workings standards calibrated in terms of the quantum Hall effect. The voltmeter DC voltage is calibrated by comparison to a NIST 10 V Josephson Voltage Standard (JVS). Both the resistance and DC voltage calibrations are carried out by the NIST Quantum

4.7 a - Intermediate Precision In practice the laboratory is usually interested in the extent of variability that occurs over time when it operates the method. This is called intermediate precision and describes the variability when the method is deployed in the same laboratory, perhaps on different pieces of equipment, and using different analysts on the staff. It is predictable that this will give a value between repeatability and reproducibility. Sample Preparations Stock solution of Trazodone

Hi Families, It is almost the end of the year and the students have accomplished so much. I am fortunate enough to witness exploration and creativity every day with your children. The growth I’ve seen so far is remarkable! Shy little ones who barely spoke back in September are now approaching me and telling me all about their weekend and their best play date party EVER! It has been an exciting month in the rainforest! Measurements are all around us and the children have been “measuring up” to everything

Three materials, either in use for hip protective pads or with plausibly suitable characteristics, were selected for evaluation. The first material was 3D vertically lapped nonwoven fabric; the second material was the same, but with its upper and lower surfaces covered by single layers of jersey-knitted fabric. The third material was polyurethane closed-cell foam that was claimed to be suitable for hip protective pads by the manufacturer. The mean values of experimental pads’ thicknesses were 14

Possible Hidden Transmission Issues Transmission problems are no joke. Sometimes they can be very easy to pinpoint, while other times it may take a full inspection to determine what is possibly wrong. Regardless of whether it seems like the transmission or not, it is important to have your car looked at. What may not seem like a transmission to an unsuspecting car owner, can end up causing a lot of damage once it is eventually discovered. Here are some transmission issues that may not be immediately

Blood sampling is also useful, and protein and cell levels can be used to calculate a LRINEC score. LRINEC stands for Laboratory Risk Indicator for Necrotizing Fasciitis and is a great tool for distinguishing common skin infections from necrotizing fasciitis. In addition, its score is used to determine if immediate surgical debridement is necessary. Measurements included in the LRINEC score is C-reaction protein, white blood cell count, hemoglobin, sodium, creatinine, and glucose (16). CRP levels
