The answer surprises the group of student science teachers portrayed in this case study.
To explain the phenomenon they must figure out the interactions between two clusters of concepts...
Those improvements have been accompanied by a rise in price.
This case study explores whether or not the amount of refractory metals used in modern spark plugs accounts for this increase.
This case study describes the application of a variety of microscopy techniques to examine a failed motorcycle suspension to determine the root cause of the failure.
Outwardly the appearance of a spark plug has not changed—but internally there have been many improvements. He was found to have thrombocytopenia, anemia, and splenomegaly. A 36-year-old male presented to the clinic for routine warfarin monitoring. In the lab, a medical technologist noted that the volume of packed red cells appeared higher than normal. Fellow, Surgical Pathology Mayo Clinic Jorge Torres-Mora, M. Consultant, Division of Anatomic Pathology Mayo Clinic Assistant Professor of Laboratory Medicine and Pathology Mayo Clinic College of Medicine A six-year-old boy presented with fever and bone pain. He had a bone marrow biopsy, which showed foamy histiocytes, consistent with Gaucher disease.Many analytical tools could be used, but in this case study we focus on infrared spectroscopy and our knowledge of the chemistry of waxes and scents.Fourier Transform Infrared Chemical Imaging is a technique that that provides wavelength-specific, high resolution infrared images and the underlying spectral data used to determine chemical differences in a sample.The case pertains to medication-induced methemoglobinemia, its etiology, diagnosis, and treatmen...Does an ice cube melt more quickly in salt water or in freshwater?However, the dam's construction forever altered the Yangtze River ecosystem and the lives of local residents. This case was developed for use in the first semester of a sophomore organic chemistry laboratory to illustrate how a combination of techniques is usually required in the identification of chemical compounds. The discovery of a bacterium capable of substituting arsenic for phosphorus in its DNA was announced with much fanfare in 2010.It was immediately and very publicly critiqued by researchers posting their analyses of the paper on their blogs. In this dilemma case, the central character, a museum curator, must decide whether or not to show a painting as a hitherto “undiscovered” Cezanne.Proper sample packaging can mean the difference between a successful or a failed analysis.In techniques that analyze small areas or are used to determine trace chemical composition, packaging that appears innocuous can contribute as much material as was present initially.
