Classifying Matter by Composition

Matter: Pure Substances and Mixtures
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures. 
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated. 
A mixture is composed of two or...

Classifying Matter by State

104.0K
Chemistry is the study of matter and the changes it undergoes. Matter is anything that has mass and occupies space. Matter is all around us; the air, water, soil, mountains, even our bodies are all examples of matter. Matter is divided into three states — solid, liquid, and gas — that are commonly found on earth. The fourth state of matter, plasma, occurs naturally in the interiors of stars.

How Data are Classified: Numerical Data

38.1K
Data that are countable or measurable in specific units are called numerical or quantitative data. Quantitative data are always numbers. Quantitative data are the result of counting or measuring the attributes of a population. Amount of money, pulse rate, weight, number of people living in a town, and number of students who opt for statistics are examples of quantitative data.
Quantitative data may be either discrete or continuous. All quantitative data that take on only specific numerical...

pre-mRNA Processing02:01

pre-mRNA Processing

57.6K
In eukaryotic cells, transcripts made by RNA polymerase are modified and processed before exiting the nucleus. Unprocessed RNA is called precursor mRNA or pre-mRNA to distinguish it from mature mRNA.
Once about 20-40 ribonucleotides have been joined together by RNA polymerase, a group of enzymes adds a “cap” to the 5’ end of the growing transcript. In this process, a 5’ phosphate is replaced by modified guanosine that has a methyl group attached to it (7-Methyl...

How Data are Classified: Categorical Data

44.8K
A variable, usually notated by capital letters such as X and Y, is a characteristic or measurement that can be determined for each member of a population. Data are the actual values of variables. They may be numbers, or they may be words. Datum is a single value.
Data are classified based on whether they are measurable or not. Categorical data cannot be measured; instead, it can be divided into categories. For example, if Y denotes a person's party affiliation, some examples of Y include...

Area of Science:

  • Medical Informatics
  • Healthcare Systems Engineering
  • Clinical Workflow Analysis

Background:

  • Electronic health records (EHR) are crucial for quality care, clinician efficiency, and patient outcomes.
  • Optimizing EHR usability is essential for effective healthcare delivery.
  • Understanding clinician interaction with EHRs is key to identifying usability issues.

Purpose of the Study:

  • To investigate clinician EHR pathways during pre-rounds.
  • To characterize top EHR screens, time spent per screen, and task completion paths.
  • To identify clinician information needs and model EHR workflow.

Main Methods:

  • Structured observations of Intensive Care Unit (ICU) providers using EHRs in real-time.
  • Analysis of EHR screen navigation, duration, and task completion sequences.
  • Qualitative assessment of information retrieval processes.

Main Results:

  • Preliminary results identified key areas of clinician information needs.
  • A preliminary model of EHR workflow during pre-rounds was established.
  • Significant discrepancies in EHR screen usage among ICU residents were observed.

Conclusions:

  • Observed discrepancies suggest potential inefficiencies in EHR information retrieval.
  • There may be a 'clinician's pathology' hindering efficient access to patient data.
  • Further research is needed to optimize EHR workflows for improved usability and care delivery.
