What is a possible testable question (in correct format) That Mrs love might ask for this Sanrio?

Case Study 1: Recently, our research group in the Department have developed a simple, quick and portable analytical method for the detection of Pb2+ (a toxic heavy metal) in aqueous solutions. It is based on the fluorescent properties of the nanomaterials known as carbon quantum dots (CQD). These nanomaterials are highly soluble in water and in aqueous solutions, they emit blue-green light when irradiated with an ultraviolet light (from a UV lamp or laser diode). In the presence of Pb²+, the intensity of the light emitted by CQD decreases, and the decrease of intensity of fluorescence is related to the concentration of Pb²+. In this method, the intensity of emitted light is measured by taking a photograph of the fluorescent test sample using a smartphone camera (Iphone 8) and then determining using an image analysis software the value of image pixel variables that are related to the intensity of the blue-green light emitted by the sample. 10) Research on how a digital camera (such as…

You work in a research organization that is looking for markers of various diseases that can be used as a diagnostic for the disease. It has been reported in the past that high levels of Cu are found in the sweat of people with cystic fibrosis. One of the research projects is focused on looking for high levels of Cu in samples that can be obtained non-invasively such as saliva, sweat, hair, nails, etc. The lab will analyze large samples for Cu. What instrument would you recommend purchasing to support this work, Atomic absorption spectrophotometer or an inductively coupled plasma atomic spectrophotometer? Explain the basis for your decision.

This assignment is designed to help you learn how to determine total costs by combining direct and indirect costs for a particular department. In this GHA, you will be determining the total costs for three departments: (1) Physical Therapy (2) Occupational Therapy and (3) Speech Therapy. To determine the total costs, you will need to add the direct costs to the indirect costs using the template provided below. Please use the example provided in the assignment description if you find that you need some support understanding the required calculations. DIRECT COSTS The direct costs for each department are easily identifiable, because they are the costs that are directly attributable to the department. The direct costs are as follows: Physical Therapy (PT) Occupational Therapy (OT) Speech Therapy (ST) Total Direct Costs INDIRECT COSTS The indirect costs will need to be allocated to Physical Therapy (PT), Occupational Therapy (OT), and Speech Therapy (ST). The indirect costs in this…

Methods of Analysis Test #1: Polarity, or Effect of a charged rod on a stream of liquid: This test was used to determine the relative polarity of the unknown liquid. The liquid was allowed to run out of a buret and a charged rod was brought up next to the stream. The observations were reported as to whether or not the stream of liquid responded to the charged rod and to what degree. Try this at home with water and a plastic spoon. Rub the plastic spoon against a sweater and move it close to a small stream of water running out of your faucet! Test #2: Volatility, or Rate of Evaporation: A thermometer probe was wrapped with a strip of filter paper. This assembly was soaked in one of the liquids for one minute. The probe was removed, and the temperature change was monitored as the liquid evaporated. The results are given in Graph 1 below. (See Graph)   Graph 1: The curves generated of the change in temperature over time for the substances acetone, hydrogen monoxide, ethylene glycol,…
