Global Climate Change01:50

Global Climate Change

29.1K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Introduction to Global Positioning System01:30

Introduction to Global Positioning System

612
The Global Positioning System (GPS) revolutionized positioning on Earth, providing precise location data through satellite ranging. The GPS system was developed in 1978 by the U.S. Department of Defense  for military use, and it became available for civilian applications in 1983, transforming fields including navigation, fleet management, and time synchronization for telecommunications systems.GPS consists of satellites in medium Earth orbit, about 20,200 kilometers above the surface,...

Errors in Global Positioning System

364
Global Positioning System (GPS) technology has revolutionized navigation and positioning, but its accuracy is often compromised by various errors. These errors, stemming from environmental, satellite, and receiver-related factors, require careful mitigation to ensure reliable performance across applications.Atmospheric ErrorsGPS signals travel through the Earth’s ionosphere and troposphere, introducing delays which affect accuracy. The ionosphere is strongly influenced by charged particles,...

Global Regulatory Systems

735
Global regulatory systems in bacteria enable rapid and coordinated responses to environmental changes by integrating sensory inputs with gene expression, ensuring efficient adaptation to fluctuating conditions. Key global regulatory mechanisms include regulons, two-component systems, sigma factors, and secondary messengers.Regulons and Global RegulatorsA regulon is a collection of genes and operons controlled by a common global regulator. These regulators enable bacteria to prioritize resource...

Field Application of Global Positioning System

333
The Global Positioning System (GPS) has become an indispensable tool in fieldwork, offering unparalleled precision and efficiency for surveying, navigation, and infrastructure development. By harnessing signals from a constellation of satellites, GPS receivers determine the location of objects with remarkable speed and accuracy, often completing calculations within a second.Advantages of Modern GPS TechnologyContemporary GPS receivers are designed to meet the practical demands of field...

Types of Global Positioning System Surveys

378
GPS surveying methods vary in application, accuracy, and data collection techniques, catering to diverse surveying and mapping needs. Static GPS, kinematic GPS, and real-time kinematic (RTK) surveying are widely used. Each technique offers distinct advantages.Static GPS involves placing one receiver at a known reference point and another at the target point. It collects exact positional data by observing multiple satellite ranges over an extended period, achieving centimeter-level accuracy for...

Area of Science:

  • Public Health
  • Epidemiology
  • Infectious Disease Control

Background:

  • The World Health Assembly set a goal to eradicate poliomyelitis by 2000, with significant progress but ultimate elusiveness.
  • India achieved its polio eradication goal in 2011, and the South-East Asia Region was certified polio-free in 2014.

Purpose of the Study:

  • To review the progress and challenges in global polio eradication efforts.
  • To outline the necessary steps for achieving and securing the final eradication of poliomyelitis.
  • To consider the future use of infrastructure and resources after polio eradication.

Main Methods:

  • Analysis of wild poliovirus case counts and endemic countries.
  • Monitoring of eradication progress, including specific poliovirus types.
  • Assessment of the Global Polio Eradication Initiative (GPEI) post-cessation activities.

Main Results:

  • 2016 marked the lowest wild poliovirus type 1 cases, fewest endemic countries, and continued absence of wild poliovirus types 2 and 3.
  • The GPEI transitioned to post-cessation of Sabin type 2 following a synchronized global withdrawal in April 2016.
  • Significant progress has been made, but challenges in access, security, and operational quality remain.

Conclusions:

  • Sustained efforts, improved field operations, and robust surveillance are essential for polio eradication.
  • Sensitive surveillance and facility containment are cornerstones for global certification.
  • Emergency response capacity and strategic planning for post-eradication infrastructure use are vital.
