    why do we need three co-ordinate systems, and why do we need to convert one system to other?

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...

National Nutrition Week: Healthy diet for Adolescents

-
Image
  Who are Adolescents? As per WHO Adolescents are persons in age group 10-19 years & constitute about 1/4th of India's population. What is the need? Adolescents undergo rapid changes in body size, physiology, psychology & social functioning as it is a transition from childhood to adulthood. It is a phase of rapid growth & development hence nutritional needs vary for them & needs to be taken care. When National Nutrition Week is celebrated? 1st to 7th September every year in India to focus on various aspect of Nutrition among all age groups. What should be included in diet? Grains: 4 - 8 bowls Vegetables: at least 3 servings Fruits: at least 2 servings Meat, fish, egg and alternatives: 200 - 300 gm Milk and alternatives: 2 servings Fat/oil, salt and sugar : eat the least Fluid: 6 - 8 glasses Healthy points for adolescent girls: The menstruation related needs of the girls make the nutrient requirement/ unit body weight more than boys for them Build strong bones: ...

How to design a reconfigurable antenna? Step-by-step process.

-
Determine the frequency range and bandwidth requirements for the antenna. Choose an appropriate antenna structure, such as a patch antenna, microstrip antenna, or planar inverted-F antenna (PIFA). Choose the reconfigurable component, such as PIN diodes, switches, or varactor diodes. Design the impedance matching network, which is essential for optimal performance of the antenna. Simulate the antenna using electromagnetic simulation software, such as CST Microwave Studio, Ansys HFSS, or Keysight ADS, to verify its performance. Fabricate the antenna and integrate the reconfigurable component. Test the antenna in an anechoic chamber to verify its performance and ensure that it meets the requirements. Repeat steps 5-7 as necessary to optimize the antenna's performance. Note: These are general steps for designing a reconfigurable antenna and may vary depending on the specific requirements and constraints of the application.

Diabetes : Lets learn how to inject insulin

-
Image
  What is the need? The proper injection of insulin is very important to allow the body to function normally hence we should be very strict about the way we manage the insulin injections.  Common mistakes done: Poor mixing technique when mixing insulin. Wrong doses (because of poor eyesight). Poor injection technique—into the skin or muscle rather than the soft, fatty layer.  Not taking insulin when you feel ill. When to inject insulin? Develop a set routine, including eating your meals on time and giving the injections about 30 minutes before your meal Where to inject insulin? The injection should go into the fatty (subcutaneous) tissue between the skin and muscle.  Abdomen below the navel is the best place.  Other suitable areas are the buttocks and thighs.  These areas having a good layer of fat under the skin and are free of large blood vessels and nerves.  It is advisable to stick to one area, and the abdomen is recommended.  Avoid ...

Spotters in "Environment and Health: Insecticides" for CFM & MPH students

-
Image
Insecticides:   These are substances that are used to kill insects.  Pesticides:   It is a general term that includes  insecticides, fungicides rodenticides, herbicides,  disinfectants, repellents, and other chemicals used for the  control of pests. Insecticides are classified into 3 groups: Contact  poisons, Stomach poisons and Fumigants.  CONTACT  POISONS: These are those insecticides that kill insects primarily by contact  e.g., pyrethrum, DDT, HCH, dieldrin.  STOMACH POISONS: These  are those insecticides which when ingested cause the death of the  insects, e.g., Paris green, sodium fluoride.  FUMIGANTS: These are  those insecticides that give off vapours that have a lethal effect on  the insects, e.g., sulphur dioxide. 1. DDT  (Dichloro-diphenyl-trichloroethane) :  It was first  synthesized in 1874, by a German chemist, Ziedler . I ts insecticidal properties were discovered by the Swis...

Bajaj Set to Launch CNG Motorcycle by June 2024

-
The wait for India's first CNG motorcycle is finally coming to an end, with Bajaj Auto gearing up for its launch. According to recent reports, the company could unveil the motorcycle as early as June this year. Earlier speculations suggested a launch by 2025, but now it seems Bajaj is expediting the process. While details about the motorcycle's name remain scarce, the company aims to cater to various segments ranging from 100cc to 160cc. Rakesh Sharma, Executive Director of Bajaj Auto, highlighted the efficiency of CNG over diesel in terms of cleaner emissions. While CNG produces negligible particulate matter emissions compared to diesel, it's not a zero-emission fuel. Hence, Bajaj is expanding its portfolio to include models like LPG, compressed natural gas (CNG), and ethanol-blended fuel in the coming years. The forthcoming CNG motorcycle, possibly codenamed "Brujar E101," is in its final stages of development. Prototypes have been tested, with an estimated mile...
