The Science behind Depression

There are over 350 million people who are affected on any given day by depression across the world, making it no wonder why this is a condition that is treated as a very serious medical illness. Unfortunately, depression is also one of the most difficult mental illnesses to treat, and this creates a tough situation for all of those afflicted with the condition. There is no blanket cure or treatment for depression, and what may work beautifully for one individual could be useless for the next, so it’s important that science begins taking a good look at the big picture when it comes to fighting this disease.

In previous years, depression was often written off by medical science as simply “an imbalance of chemicals in the brain”, but research performed by modern science has come up with some rather interesting findings. One professor at the University of San Francisco’s Department of Health Sciences made the connection between depression and genetics, stating that depression could be a hereditary condition passed down from generation to generation through genes.
Another scientific breakthrough on the topic of depression found that rather than a chemical problem in the brain, depression may actually be related to cell growth and brain connections. The hippocampus portion of the brain, the part in charge of memory and emotion, has been shown to shrink as a person experiences depression. As the hippocampus shrinks, the cells and networks that make up this portion of the brain will start to deteriorate, and this could be a huge contributing factor to the depression a person may experience.

𝗨𝘀𝗲𝗳𝘂𝗹 𝗗𝗶𝗺𝗲𝗻𝘀𝗶𝗼𝗻𝘀 in Civil Engineering





















Measurement is one of the most important things in civil engineering and without measurements, we can not complete any construction. Here I have listed some basic measurements and conversion factors which are most commonly used in civil engineering. Hope it will help you in your work.


BASIC QUANTITIES AND UNITS:

QuantityDimensionSI UnitFPS Unit
MassMKgSlug
LengthLMft.
TimeTsec.sec.
ForceFNewton (N)Pound (lb)

BASIC STANDARDS:

1 inch = 25.4 millimeters = 2.54cm.
1 meter = 39.37 inches =1.09 yards.
1 liter = 0.22 galls (imp.)
1 gallon (imp.) = 4.546 liters.
1 gallon (US) = 3.785 liters.
1 Kilogram (kg) = 2.2046 pounds (lb).

METRIC UNIT OF WEIGHT/MASS:

1 tonne = 1000 kilograms = 1,000,000 grams.
1 quintal = 100 kilograms = 100,000 grams.
1 Slug = 14.606 kg
1 Slug = 32.2 lb

MEASUREMENTS OF LENGTH:

1 foot = 12 inches.
1 yard = 3 feet.
1 furlong = 220 yards.
1 mile = 8 fulongs.
1 Kilometer (Km) = 1000 meters.
1 meter (m) = 100 centimeters (cm).
1 cm = 10 millimeter (mm).

METRIC UNITS FOR LIQUID MEASUREMENTS:

1 liter = 1000ml.
1 liter = 1kg.
1 kiloliter (1000 liters) = 1 cubic meter/ 1 cu.m/ 1 m3.

CONVERSION FACTORS:

1 cu. ft. = 28.317 liters.
1 cu. ft. = 0.028 cu. meters.
1 cu. ft. = 6.24 galls (imperial).
1 cu. ft. = 7.48 galls (US).
1 imp. gall = 1.20 galls (US), liquid.
1 imp. gall = 1.03 galls (US), dry.

MEASUREMENTS OF AREA:

1 Acre = 43560 sq. ft
1 Acre = 4046.46 sq. m
1 Acre = 8 Kanals.
1 Kanal = 20 Marlas.
1 Marla = 225 sq. ft (* in some regions 272 sq. ft)
1 Marla = 15.50 sq.m


MISCELLENIUS CONVERSION FACTORS:

1 cu.m = 35.32 cu.ft.
1 Pound = 4.448 Newton (Force).
1 klb = 4.448 kN.
1 Psi (lb/sq.in) = 6.689 Pascal (N/sq.m)
1 (lb/sq. ft) = 0.048 (kN/sq.m)
