Abstract:
Fly ash is an industrial waste. Coir dust is a by-product of coir fiber production. A novel low cost hybrid polymer composite, using coir dust and fly ash particle reinforcements is proposed in this paper. Investigation of the dielectric behavior of this hybrid polymer composite proves its potential as a marketable product. Individual compacts of coir dust, fly ash, and a mixture of both were also prepared for comparison with the hybrid polymer composite. Hand lay-up method was adopted for preparation of the compacts. The novel hybrid ...

Nausea and vomiting are fairly common symptoms resulting in emergency room visits and in hospitalization. Some common medical conditions that result in these symptoms include “Gastroenteritis (food poisoning), pregnancy, complication of chemotherapy in cancer patients, and major surgical procedures”1.
Ondansetron is the most effective anti-vomiting drug available today. It is available in both injectable and oral forms and is more efficient than any other available medications that treat nausea and vomiting2.
Ondansetron was developed in the 1980’s by a scientist working for a leading pharmaceutical laboratory in London, and was finally approved ...

Nuts? No thanks, many regretfully say while clearly tempted.
Nuts, after all, get more than half of their calories from fat and are notoriously known for being high in fat. Nuts have a greater ratio of fat calories than whole milk, ground beef, and even cheese have.
Nutritionists have warned in the past that nuts are a dangerous food item; nuts not only will cause one to gain weight but they will also increase one's risk for heart disease.
Well, nut lovers, take heart. The bad reputation nuts have unjustly earned is more ...

Editor's note: Though the NHSJS usually features work by high schoolers, it occasionally gets the chance to showcase extraordinary research done by young scientists across the country. This project was done by a student in third grade - we hope you enjoy it.
Introduction:
The project investigates whether the external application of turmeric reduces the growth of fungi and bacteria in foods.
Background:
Turmeric (Curcuma longa) is a rhizomatous herbaceous perennial plant of the ginger family, Zingiberaceae. It is native to tropical South Asia and needs temperatures between 20 °C and 30 °C and a considerable ...

Various proposals have been put forth to tackle the seemingly insurmountable task of ending world hunger. Though the causes of world hunger are still being debated, many argue that “people are hungry because they cannot afford food,” not because food is scarce.1 If healthy food were inexpensive, then it would be much easier to address the problem. It is through this approach that lies the vast potential of cultured meat: taking stem cells from livestock, and proliferating them to create edible muscle fibers.
Scientists across the world are attempting to use ...
