How is camphor used?

Camphor relieves coughing when applied to the chest and can be found in Vicks VapoRub and BENGAY. It is also a topical treatment for toenail fungal infections, warts and cold sores. Other known uses include treating respiratory and heart disease symptoms. Since the 1980s, camphorated oil is no longer available for purchase in the United States because of safety concerns due to its high percentage of camphor; however, it is available on the Canadian market. Camphor is manufactured from turpentine oil; camphor-related products should not be heated on a stove or in a microwave because the product..

What internal organs are located by the lower left side of the back?

The left lumbar region is one of nine regions of the abdominal cavity, and it contains organs from both the digestive and excretory systems. Both the small intestine and the descending colon are components of the digestive system, and they assist the body in converting food into energy and nutrients for the body. The kidneys are part of the excretory system, which filters the blood and removes toxins from the body as well as regulates fluid and electrolyte balances in the body.

How do cirrus clouds form?

Cirrus clouds can appear as finger-like streaks or can be more uniform in texture when close to approaching warm fronts. Streaks within cirrus clouds can appear in many different sizes and shapes and can also stretch vertically and horizontally. The primary factors involved in the shaping of cirrus clouds are elevation, wind changes and how rapidly the ice crystals within the clouds fall.

How do I describe the typical conditions necessary for fossil formation?

Rapid burial is essential for fossil formation because it prevents excessive decomposition. Dead animals that do not receive rapid burial decompose quickly, leaving nothing behind capable of fossilization.\nAfter burial sediment accumulation presses the potential fossil deeper into the Earth's crust. During this process, the increasing pressure of the sediment layers squeezes all the remaining moisture out of the fossil. Minerals gradually infiltrate the pathways left by the escaping water. This phenomena is called perimineralization. Live Science states that this process is often called ..

What caused the Tangshan earthquake?

The Tangshan earthquake occurred at 3:42 a.m. local time and lasted approximately 15 seconds. It measured 7.8 on the Richter scale. A 7.1 aftershock occurred in the region 16 hours later. The Tangshan earthquake caused approximately 242,769 deaths and destroyed the city of Tangshan. As of May 2015, it is considered the second deadliest earthquake in the world.

Why do conifer trees go brown?

Browning in conifer trees can be prevented by following proper procedure and timing when trimming hedges. It is best to trim only twice or thrice a year and never during hot weather or in the fall. When there's already some browning in the trees, it can be controlled with nonchemical solutions like tying healthy shoots to fill bare areas. Browning caused by pests can be remedied by using an insecticide, which should be applied as early as possible.

What does it mean if an element is isoelectronic?

Nitrogen and oxygen with an extra electron are isoelectronic, because their valence electron shells each contain five electrons. The positively-charged lithium atom is an isoelectronic partner with the helium atom, because they both have two electrons in their outermost shells. Some isoelectronic pairs have identical pairs of electrons extending deep into the inner electron shells, such as ionized sulfur and argon.

What are some interesting ways to use crystals in a science project?

To make crystal or rock candy, the student dips wooden skewers in water and then rolls the wet ends into white sugar. As they dry, he dissolves 1/2 cup of white sugar in 1 cup of water, stirring constantly. He continues to do this until no more sugar can possibly dissolve because the water is completely saturated with the crystals. Then, he heats the sugar water to a boil and turns the heat down to a simmer for five minutes until the remaining sugar in the pan dissolves and the liquid turns clear.\nOnce the sugar water cools down, the student pours it into jars and mixes it with food coloring ..

What are natural gemstones and how do they form?

Many gems form deep in the crust and mantle of the Earth under extreme heat and pressure. These include diamonds and red garnets. The rocks containing these potential gems reach the surface either through uplift during mountain formation, mining operations, or magmas surging up from the earth. When magma reaches the Earth's surface as lava and cools, weathering can break it down and reveal the gems inside. This is why gems such as rubies and jade, although formed in the depths of the Earth, have been found in the Himalayas.\nGems also come from the upper part of the Earth's crust whe..

How do you read a femoral artery illustration?

There are several branches of the femoral artery, Inner Body reports. The largest of these, the common femoral artery, is an extension of the iliac artery located at the inguinal ligament, which serves as the boundary between the leg and the pelvis. From the inguinal ligament, the common femoral artery parallels the head and neck of the femur before branching into the deep femoral artery and the superficial femoral artery.\nThe superficial femoral artery curves to closely parallel the bend of the thighbone, Inner Body reports. At the knee, the artery curves and descends to form the popliteal a..
