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. Rendering th...

Spotters in "Environment and Health: Mosquitoes- Anopheles" for CFM & MPH students

-
Image
Anopheles Mosquito: Also known as the sophisticated mosquito. The flight range is 3-5 km. Around 45 species of anopheles mosquitoes have been found in India but only a few of them have been incriminated as vectors or carriers of malaria. These are An. fluviatilis & An. minimum (foot-hill regions), An. sundaicus & An. stephensi (coastal regions) and An culicifacies & An. philippinensis (planes). 1. Eggs: Important points: Eggs laid on the surface of the clean water. 100-250 at a time. This stage lasts for 1-2 days. Laid singly, boat-shaped & possess lateral floats. 2. Larva: Important points: The larva is a free-swimming creature. Passes through 4 stages called ' instars ' with moulting between each stage. Floats horizontally in water/ rests parallel to the water surface. No siphon tube at the tip of its abdomen.  Palmate hairs present on abdominal segments. 3. Pupa: Important points: The pupa is comma-shaped in appearance, with a large rounded cephalothorax and...

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.

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...
