 Entomology

It is a branch of science in which we study about insects. All insects are not harmful to plants. Insects on a plant present in a certain number are not harmful but when they exceed this number then they cause problems. 

In forest entomology, we study about those insects which cause benefit or harm to trees. We consider the forest as an important economic resource in the 1800. We get both major and minor forest produce from forests. 

Insects harm forest resources so forest acts came about to conserve and maintain forest resources. 

Useful roles of insects-
Honeybee- honey and wax
Silk worm - silk

Damages caused to the forest and timber by plants-
Forest fires cause 4% loss to forests
Insects- 24% loss
Diseases- 24%
Deficiency or environmental stress - 24% loss

So, insects play a major role of insects in damages caused to forest resources.

Diary -24th July

  I tried learning Greek and Japanese. German is too easy and boring but I will get back to it as soon as I can. I wonder why not learn pretty much any real language on Duolingo? It will give me the variety I want.  The Greek letters sound just like Hindi letters. But the Greek letters are also like English letters. Here is my secret to Indian English. In Japanese gohan is rice. It sounds like go or cow or white and anna which means grain. Recipes I want to try: https://www.archanaskitchen.com/vegetarian-thukpa-recipe-by-saransh-goila-india-on-my-platter/amp https://www.cookwithmanali.com/thandai-powder/ Maggie masale noodles tastemaker and maggie masala e magic recipe https://hebbarskitchen.com/maggi-masala-powder-maggi-masala-magic/ Science and animals Hippos  https://www.usatoday.com/story/news/2022/09/27/what-do-hippos-eat/10303668002/

How to make clip art faces-Part 1: Pretty girl face with braided hair decorated with flowers

Image
  The use of circles makes a face look very amiable. And, this picture isn't as complicated as it seems.  I have used MS Word to make this clip art. But, you can use any software of your choice.  Let's begin. You will find all the shapes used in this picture in MS Word in this way: Insert>>Shapes>> Face Select an oval.  To change the color of the oval, right click on the oval, you will find 'fill' and 'outline' options.  Choose any color of your choice. I have played around a lot with colors. I must insist that you do the same according to your tastes and requirements. Hair Here is how we use the ovals to assemble the hair.  Like this, also use ovals to complete the other side.  Flowers Let us draw a single flower then we will copy and paste it again and again.  Start with a circle.  Then draw two more concentric circles of colors you like.  Now add the petals using the teardrop shape.  Use another color to draw an inner...

Object oriented programming in dart concepts

   No introduction, let us go straight to concepts :-) What is object oriented programming? It is a paradigm that involves classes and objects. First, we will understand paradigms in detail then we will understand how object oriented programming falls in this framework. Then we will explore what are classes and objects. After that we understand object oriented programming in Dart language. So, keep scrolling to get crystal clear concepts.  What is a paradigm? Paradigm is a method to solve a problem.  It may include some tools or coding languages. We can use any  programming language to solve a problem but that approach used to solve it is called a paradigm.  Types of paradigms Paradigms separate programming languages into different categories on the basis of features of various programming languages.  1. Imperative programming paradigm Statements change the state of the program.  They give commands to the computer. It  means this type of prog...
