Data Analyst Vs Business Analyst Vs Data Engineer Vs BI Specialist

  Data Science - Complete Track • Step 1 - Identify the business problem/value addition/question – ( Data Insights ) this has to be the starting point. • Step 2 - Data availability ( Data Governance ) - Have the structure of your data set defined – The real challenge starts here-                o Do we have the data?                o Do we have access to the required data? • Step 3 -Getting Data ( Data Mining / Data Pipeline ) – How to collect the data from different sources in the system • Step 4 - Data preparation (ETL / ELT) – Once you have data there will be lot of cleaning and preparation required, reduce/increase/combine/split the predictors, determine and eliminate outliers, populate missing values convert few categorical variables into numerical etc. • Step 5 –Exploratory Data Analysis (EDA) – In this step we do descriptive and diagnostic analysis of the existing data. We build multiple graphs that give us direction towards the next steps of predictive analytics. We migh

Life-Saving Covid Treatment

  What is a monoclonal antibody and how does it work? The body’s immune system generates antibodies — specific protein molecules — as a defense mechanism against unfamiliar molecules, called antigens. Molecules from pathogens like bacteria and viruses can act as antigens, prompting the production of antibodies that bind to antigens. This tells specialized cells of the immune system to kill the invading pathogen. Monoclonal antibodies work specifically against a particular portion on an antigen called the epitope, thereby exerting very targeted action. The Role of Antigens & Antibodies in Vaccinations Vaccines contain antigens which stimulate the B lymphocytes of the immune system to respond by producing plasma cells which secrete disease specific antibodies. Some of the B cells become memory B cells , which will recognize future exposure to the disease. This results in a faster and more intense production of antibodies, which effectively work to eliminate the diseas

Covid 19 Rapid Antigen Test Kit

  Antibody tests are useful to help track the spread of a contagious disease , disease that is readily spread. It can be very useful to identify those who should be vaccinated urgently, and to select the donors for convalescent plasma therapy. Antigens are molecules capable of stimulating or encouraging an immune system response. Each antigen has distinct surface features or structures called epitopes, generating specific responses. What are Antibody and Antigen ? An antibody (Ab), also known as an immunoglobulin (Ig), is a large, Y-shaped protein used by the immune system to identify and remove foreign objects such as pathogenic bacteria and viruses.  These antibodies are produced by B cells of the immune system due to exposure to antigens. Each antibody contains a paratope which recognizes a specific 'epitope' on an antigen, acting like a lock and key binding mechanism. This binding makes possible to eliminate antigens from the body, either by direct neutralization or by ‘tag

Portable Pulse Oximeter

Image
  Portable Pulse Oximeter Portable Pulse Oximeter is a noninvasive and painless device to measures oxygen saturation level, or the oxygen levels in blood. It can rapidly detect even small changes in how efficiently oxygen is being carried  to all of its cells, tissues, and organs. Portable Pulse Oximeter can be used to measure oxygen saturation levels along with heart rate. Portable Pulse oximeter can be used to monitor the health of a person with any type of condition that can affect blood oxygen levels. These conditions include: 1 . chronic obstructive pulmonary disease 2 . asthma 3 . pneumonia 4 . lung cancer 5 . anemia 6 . heart attack or heart failure 7 . congenital heart defects How Portable Oximeter Works To measure oxygen level, a probe that looks like a bag clip is placed onto fingertip, toe, or earlobe. Light beams pass through the blood, measuring the amount of oxygen gas. It does this by measuring changes of light absorption in oxygenated blood containing high oxygen l
