Summary on Remote Sensing: Definition and Basic Concept

  • Remote Sensing refers to the technique of acquiring information about objects or areas without physical contact, typically via satellites or sensors placed remotely.
  • Satellites detect and interpret the energy (rays) reflected or emitted from objects on Earth, such as water bodies, buildings, or vegetation, to provide detailed spatial information.
  • This process allows identification of features like water presence, buildings, and vegetation

1. Apply Descartes's rule of signs, find the nature of the roots of the equation:
x ^ 4 + 2x ^ 2 + 3x - 2 = 0

C1. Apply Descartes’ Rule of Signs

Given equation:

x4+2x2+3x−2=0x^4 + 2x^2 + 3x - 2 = 0x4+2x2+3x−2=0

Consider

f(x)=x4+2x2+3x−2f(x) = x^4 + 2x^2 + 3x - 2f(x)=x4+2x2+3x−2

Signs of coefficients:

+,  +,  +,  −+,\; +,\; +,\; -+,+,+,−

Count sign changes:

  • +++ to +++ → No change

  • +++ to +++ → No change

  • +++ to −-− → 1 change

  • Therefore,

Number of positive real roots =

Fermentation

* Fermentation is a metabolic process converting carbohydrates → acids, gases, or alcohol using yeasts, bacteria, fungi, or molds, mostly anaerobically .
* One of the oldest applied microbiology techniques.
* Enhances nutritional quality, preservation, flavor, and food safety.
* Used in food, pharmaceuticals, biofuels, biopolymers.
Biochemical Basis
* Begins with glycolysis → pyruvate.
* If no oxygen, pyruvate is reduced to regenerate NAD⁺, allowing glycolysis to continue.
* Fermentation
