He is alert and oriented X3, breathing is quiet and unlabored.  Skin and mucous membranes are pale and dry.  There is 90 mL of dark, concentrated urine in a bedside urinal.  An endoscopy reveals esophageal metaplasia and numerous gastric and duodenal ulcers.  A chest x-ray shows normal lung fields with myocardial hypertrophy.  An electrocardiogram (ECG) shows sinus tachycardia with occasional Premature Ventricular Contractions (PVCs). Vital signs are:  36.9 C, 112, 30, 94/42, and 98% Oxygen saturation. The following laboratory values were assessed: Serum Electrolytes Na 130 mEq/L    Cl 89 mEq/L   K 6.2 mEq/L BUN 52 mg/dl   Creatinine 2.4 mg/dl   CO2 16 mmol/L Ca 7.6 mg/dL   Mag 1.5 mEq/L   Phosphorous 4.4 mg/dL Glucose 138 mg/dL   Albumin 3.0 g/dL   Lactic Acid 1.8 mEq/L   Mr. Collins’ calcium levels may have been caused by which of the following:

Consider the scenario shown below, with four different servers connected to four different clients over four three-hop paths. The four pairs share a common middle hop with a transmission capacity of R = 200 Mbps. The four links from the servers to the shared link have a transmission capacity of RS = 10 Mbps. Each of the four links from the shared middle link to a client has a transmission capacity of RC = 30 Mbps.   ‘ What is the maximum achievable end-end throughput (in Mbps) for each of four client-to-server pairs, assuming that the middle link is fairly shared (divides its transmission rate equally)?
