ORS : A boon in dehydration

-
Image
What is ORS? Oral re-hydration salts: It is a glucose-electrolyte formula given by WHO/UNICEF, used for correction of acute diarrhea due to all causes and dehydration in all age groups with aim to reduce mortality. It is available in powder form in sachets/ ready-made solution or it can be easily made at home. How it works? The combination of electrolytes and sugar together stimulates water and electrolyte absorption from the gut and hence  capable of correcting water and electrolyte deficit in conditions such as diarrhea and vomiting. Reasons to celebrate ORS day? ORS Day is celebrated every year on 29th July:  To spread awareness about the importance of Oral Rehydration Salts (ORS) as a low cost method of health intervention.   Among infants and young children, acute diarrhoeal diseases are one of the leading causes of mortality in many developing countries.   Dehydration particularly affects infants, children and old people.  Diarrhea...

Spotters in "Environment and Health: Mosquito control Measures" for CFM & MPH students

-
Image
The integrated approach of mosquito control: This is an approach that avoids the excessive use of any one method (e.g insecticides) but tries to combine one or more methods with a view to obtain maximum results with minimum inputs and also to prevent environmental pollution with toxic chemicals & development of insecticide resistance. The various methods of mosquito control are as follows: 1. Anti- Larval Measures: (a) Environmental Control: Important Points: Source reduction : Mainly the elimination of mosquito breeding places by minor engineering methods such as  Filling- of cesspools & open ditches and arrangement for adequate collection, removal, and disposal of sewage & wastewater. Leveling & getting rid of water-holding containers such as discarded tins, empty pots, broken bottles, coconut shells, etc. Drainage of breeding places, and  Water management (e.g intermittent irrigation) & removal of aquatic plants or destruction by herbicides.

How engineering education is getting disrupted by chatGPT?

-
What is ChatGPT? ChatGPT is a state-of-the-art language model developed by OpenAI that is designed for generating text-based responses to prompts in a conversational style. It is trained on a diverse range of internet text and can answer questions, generate creative writing, summarize long texts, among many other tasks that require language understanding and generation. How does ChatGPT work? ChatGPT works using a deep learning model called Transformer, which is trained on a massive amount of text data using unsupervised learning to generate text based on the input prompt. The model uses an attention mechanism to determine which parts of the input to pay attention to when generating the output, allowing it to generate coherent and context-aware responses. What is the impact of ChatGPT on engineering education? Following are the major impact on the engineering education. 1. Increased Accessibility : ChatGPT allows students to access information and knowledge from anywhere, at any time, ...
