In this task, you are given a question and answer options for that question. Using this information, you have to classify each text into different topics: medicine, nursery, psychology, chemistry, pharmacology, biology.

Question: A 72-year-old man with a pathological fracture in the left femur goes to the Emergency Department. After the surgical intervention, the diagnostic study was performed to find out the underlying pathology with the following findings: hemoglobin 9.5 g / dl, total protein 11 g / dl, (VN: 6-8 g / dl), serum albumin 2 g / dl, (VN 3.5-5.0 g / dl), beta 2 microglobulin 6 mg / l (VN 1.1-2.4 mg / l), serum creatinine 1.8 mg / dl (VN: 0 , 1-1.4 mg / dl). Indicate what would be the diagnostic tests necessary to confirm the most probable diagnosis: 
 Options:  <0> Radiological bone series and bone marrow aspiration. <1> Serum and urinary electrophoresis and renal function tests. <2> Bone marrow aspirate and serum calcium concentration. <3> Bone marrow aspiration and serum and urinary electrophoresis. <4> Biopsy of the pathological fracture and radiological bone series.

Question: Van Deemter's velocity equation tries to justify the contributions of the different effects that cause the widening of the chromatographic band, which are basically of four types: 
 Options:  <0> Eddy diffusion, dead volume and resistance to convection in both phases, mobile and stationary. <1> Length of the chromatographic column, longitudinal diffusion in axial and radical direction, and Joule effect. <2> Kinematic viscosity of the mobile phase, mass transport between the mobile phase and the stationary phase, transversal and longitudinal diffusion. <3> Effect of mass transfer in the stationary phase, in the mobile phase, Eddy diffusion and longitudinal molecular diffusion. <4> Molecular diffusion in axial direction, radical atomic diffusion, internal pressure of the column and viscosity of the mobile phase.
