  • Importance of Following Orders

    Importance Of Following Orders I am writing this essay on the importance of following order because I recently disobeyed a few General orders. Our commanders put out orders and make them very clear to us for multiple reasons. One of the main reasons is that these orders are there to protect us as Soldiers and not only our images but the images of our fellow Soldiers and the Army itself. The Army and our commanding officers have our best interests at hand and they put in place the orders they do for...

  • Membrane Permeability

    simulated experiment. Activity One: Simple Diffusion Two beakers were placed next to each other and joined by a membrane holder. Four membranes were used and each possessed a different molecular weight cut off (MWCO) consisting of 20, 50, 100, and 200 MWCO; and were tested using NaCl, Urea, Albumin, and Glucose solutions. First, the 20 MWCO membrane was placed in the membrane holder between the beakers and the first solute studied was NaCl. A 9mM concentrated solution was dispersed into the left...

  • Hyponatremia

    commonly defined as a serum sodium concentration ≤135 meq/L [2]. An overview of the causes of hyponatremia will be presented here (table 1). Most of the individual disorders are discussed in detail separately, as are issues related to diagnosis and treatment [1,3]. (See "Diagnosis of hyponatremia" and "Overview of the treatment of hyponatremia".) It should also be emphasized that, in selected patients, multiple factors may contribute to the fall in the plasma sodium concentration. Symptomatic...
