‘Thrive’ plants grew more than any other plants as these plants had additional scientifically-proven ingredients that targeted plant health and growth. One of the main ingredients that the Thrive fertiliser includes that the organic fertiliser doesn’t is boron‚ which helps build cell wall strength and seed development. As it was said in the introduction‚ some fertilisers can have extra ingredients to target good plant health‚ like the

There exist two stable isotopes of boron‚ and the average mass of a boron atom is 10.81 amu. Assuming you were able to isolate only a single boron atom‚ the chance that you would randomly get one with a mass of 10.81 amu is A. 0% B. 0.81% C. about 50% D. 10.81% E. 100% 5.

Unit-II: MOS/BiCMOS Process Technology and Integration Introduction BiCMOS = CMOS + Bipolar (BJT) structures on the same substrate. Advantanges of CMOS device: 1. Low Power 2. High digital IC density. Advantages of Bipolar transistors: 1. Ability to deliver large drive currents 2. Capability to rapidly charge heavy loads. The implementation of digital bipolar circuits with emitter-coupled logic (ECL) gates permits small logic swings and excellent noise immunity

it’s being used as an antiseptic‚ helping to cure people‚ getting rid of pests‚ or even assisting fruit trees in their growth. It is actually the most important source of the element boron‚ and has been used for years as a “water softening agent.” Borax was found forming in saline lakes‚ or one may find it in Boron‚ California. Historically‚ “the first Borax specimens came from several dry lake deposits in Tibet” (The Mineral Borax). This experiment was conducted to determine the standard entropy

Assignment On Engineering Materials (Glass) Introduction Glass is a non-crystalline solid material. Glasses are typically brittle‚ and often optically transparent. The most prevalent type of glass‚ used for centuries in windows and drinking vessels‚ is soda-lime glass‚ made of about 75% silica (SiO2) plus Na2O‚ CaO‚ and several minor additives. Often‚ the term glass is used in a restricted sense to refer to this specific use. [pic] [pic]Roman Cage Cup from the 4th century A.D. In

As technology continues to develop in sport‚ new composite materials are replacing the old traditional materials. Tennis rackets are no longer made of wood and sheep intestines but instead have been replaced with graphite and the strings are now made of nylon. This essay intends to discuss how old materials have been replaced by new composite materials‚ the manufacturing process and the benefits to the designer and consumer. Due to new technology‚ the tennis racket has changed materials. Throughout

Heavy metals in surface water systems can be from natural or anthropogenic sources. Excess metal level in surface water may pose a health risk to humans and the environment (WATERSHEDSS‚ 1995). Plants require a trace of iron‚ copper‚ manganese‚ boron‚ molybdenum‚ chlorine‚ zinc and nickel which are called micro-nutrients. Purpose: To test the river waters: from Rocky Mountain Range (Site 1‚ Cut Bank Creek; Site A Two Medicine River) to Sullivan Bridge (Site 3C‚ Marias River)‚ for chemicals
