Multiple-Step

Examples of Multiple-Step in the following topics:

• Income Statement Formats

  • Income statements are commonly prepared in two formats: multiple-step and single-step.
  • Income statements are commonly prepared in two formats: multiple-step and single-step.
  • In the multiple-step format revenues are often presented in great detail, cost of goods sold is subtracted to show gross profit, operating expenses are separated from other expenses, and operating income is separated from other income.
  • In the single-step format, all expenses are combined in a single section including cost of goods sold.

• Heterogeneous and Multiple Equilibria

  • Heterogeneous equilibria involve reactions with compounds in different phases; multiple equilibria involve reactions with two or more steps.
  • In multiple equilibria, the equilibrium can be split into two or more steps.
  • These equilibria can be split into two steps:
  • Thus, for a reaction involving two elementary steps:
  • Calculate the equilibrium constant of a multiple-step reaction, given the equilibrium constant for each step

• Rate-Determining Steps

  • The rate of a multi-step reaction is determined by the slowest elementary step, which is known as the rate-determining step.
  • The reaction mechanism is the step-by-step process by which reactants actually become products.
  • In kinetics, the rate of a reaction with several steps is determined by the slowest step, which is known as the rate-determining, or rate-limiting, step.
  • The fact that the experimentally-determined rate law does not match the rate law derived from the overall reaction equation suggests that the reaction occurs over multiple steps.
  • Since the first step is the slowest, and the entire reaction must wait for it, it is the rate-determining step.

• Antiviral Agents that Prevent Virus Uncoating or Release

  • Different approches are used to target the initial and final steps of a virus life cycle.
  • The entry mechanism is complex, consists of multiple steps and involves host cell structures.
  • There are two main strategies used to design antiviral drugs at this step:
  • Another drug target is the uncoating step during viral infection.
  • This step is performed by viral or host enzymes, or by capsid dissociation alone.

• Diprotic and Polyprotic Acids

  • Diprotic and polyprotic acids contain multiple acidic protons that dissociate in distinct, sequential steps.
  • Dissociation does not happen all at once; each dissociation step has its own Ka value, designated Ka1 and Ka2:
  • This first dissociation step of sulfuric acid will occur completely, which is why sulfuric acid is considered a strong acid; the second dissociation step is only weakly dissociating, however.
  • Take, for example the three dissociation steps of the common triprotic acid phosphoric acid:
  • The titration curve of a polyprotic acid has multiple equivalence points, one for each proton.

• Future Value, Multiple Flows

  • To find the FV of multiple cash flows, sum the FV of each cash flow.
  • Finding the future value (FV) of multiple cash flows means that there are more than one payment/investment, and a business wants to find the total FV at a certain point in time.
  • The first step in finding the FV of multiple cash flows is to define when the future is.
  • If the multiple cash flows are a part of an annuity, you're in luck; there is a simple way to find the FV.
  • The FV of multiple cash flows is the sum of the future values of each cash flow.

• Replicative Cycle of Influenza A

  • The infection and replication is a multi-step process:
  • The vRNA either enters into the cytoplasm and translated (Step 4) or remains in the nucleus.
  • Other viral proteins have multiple actions in the host cell—including degrading cellular mRNA and using the released nucleotides for vRNA synthesis, and also inhibiting translation of host-cell mRNAs.
  • The vRNA and viral core proteins leave the nucleus and enter this membrane protrusion (Step 6).
  • Step 1: Binding Step 2: Entry Step 3: Complex formation and transcription Step 4: Translation Step 5: Secretion Step 6: Assembly Step 7: Release

• Solving Systems of Equations Using Matrix Inverses

  • A system of equations can be readily solved using the concepts of the inverse matrix and matrix multiplication.
  • A system of equations can be readily solved using the concepts of the inverse matrix and matrix multiplication.  
  • Step 1:  Set up matrix A, which are the coefficients of all the variables from each equation from the left hand side of the equal sign:
  • Step 2:  Step up matrix B, which are the constants on the right hand side of the equal sign:
  • This can be done by hand, finding the inverse matrix of $[A]$, then performing the appropriate matrix multiplication with $[B]$.

• Introduction to the Writing Process

  • In high school, students usually submit their work in multiple stages—from the thesis statement to the outline to a draft of the paper, and finally, after receiving feedback on each preliminary piece, a completed project.
  • But there was a time when she followed the recipe step by step and by doing so learned exactly what happens when you leave out one ingredient or overdo another. 
  • As you read them, consider what might be entailed in each step.
  • Can you figure out why you might need each step?
  • You might ask, "Why does there need to be a step for revising and then a separate step for editing and proofreading?"

• Stages of Business Buying

  • An organization can decide to use several suppliers, called multiple sourcing.
  • Multiple sourcing reduces the possibility of a shortage by strike or bankruptcy.
  • This 5 step process is mainly used with new-task purchases and several stages are used for modified rebuy and straight rebuy.
