ation: Biotechnology Using Plants to Reverse the Effects of Environmental Problems. Introduction In the last century the population has increased by 6 billion and by 2050 is expected to reach 8 Billion, this coupled with global industrialisation has placed huge stresses on the environment, affecting sustainability and causing buildups of organic and inorganic contaminants throughout the biosphere, most notably in the rhizosphere (Ward & Singh, 2004). Phytoremediation coming from the Greek word

Material Properties of Steel Steel is an alloy of iron, with carbon being the primary solute in the solid solution. It is a polycrystalline solid with grain diameter from 10 to 20 micro-meter (Ashby et al). The presence of impurity like carbon causes the crystal lattice distortions to increase, hence making giving steel better hardness, yield strength, and tensile strength, at the cost of ductility. Pure iron being very ductile but comparatively weak, steel is widely because of its greater load bearing

The carbon cycle on Earth is essentially how all organisms maintain life on our planet. According to the article “The Carbon Cycle and The Earth’s Climate,” carbon is stored inside our Earth and is released in our atmosphere, plants then combine this element with sunlight and water to go through the process of photosynthesis. Photosynthesis allows plants to form carbohydrates that store energy and this energy is later used to carry out life functions. Photosynthesis is also responsible for other

constriction. We used primary as a sours of power for the old bicycle which included parts for washing machine. There are components are shaft, drum, pedestal bearing, gear, chain, fasteners, flywheel, and shaft mounted are on the frame. Frame made steel or iron material, and it is fabricated. The inner drums is attracted one side of a pedal shaft. Rotational force turns the drum via a drive gear attached to the opposite side of the pedal shaft. Figure 6 frame 1.10.2 Shaft Shaft is the

Aerobic TNT biotransformation by bacteria has been exensively researched and leads to the reduction of 1 or 2 nitro groups. Many studies have proved that many isomers of amino-nitro-aromatic compounds such as hydroxyl-aminodinitrotoluenes (HADNT), amino-dinitrotoluenes (ADNT), diamino-nitrotoluenes (DANT), dinitroaniline (DNA), and polynuclear condensation products like azoxytoluenes are the aerobic partially reduced products of TNT known to be recalcitrant and accumulate in the environment without

It can be concluded that mixed primary and secondary iron nanoparticles were synthesized in Mt and PVP involved borohydride reduction system. In addition, the nanoparticles contained an iron oxide-coated α-Fe core and a PVP surface layer. Also, the clay-polymer interactions made PVP not only adsorb on the external surface but also intercalate into the interlayer space of Mt particles, developing a polymer barrier on the clay mineral surfaces. Due to the barrier-related steric hindrances and/or alkaline

What is a magnet? Magnet is an object that can create magnetic field by itself. It is usually made from iron. It had a pulling force called magnetism. The pulling force is able to pull at certain things like objects made of iron or steel. It can attract or repel other magnetic objects that are not even magnetized and of course other magnets too. Due to the characteristic of a magnet, it can give a great impact to our world. It has many benefits to the industrial field, the transportation in our modern

Literature Review Introduction Coagulation and flocculation processes are essential in a number of diverse disciplines including biochemistry, rubber manufacturing and in water and wastewater treatment (Bratby, 2006). These processes are typically used in destabilizing, agglomerating and subsequent removal of particles. Coagulation is a physico-chemical process which neutralizes the colloidal particles in water by a chemical called coagulant. The neutralization forces the colloidal particles to join

In a study by (González, Rodríguez et al. 2017) the influence of deep cryogenic treatment followed by a double tempering at 150°C on the erosive wear resistance of high velocity oxy-fuel (HVOF) WC-10Co-4Cr coating was evaluated. Austenitic 304 stainless steel plates (400 mm_95 mm_7 mm) were used as substrates. Agglomerated and sintered WC-10Co-4Cr Praxair spherical powder with particle size ranging between 20 and 45 µm was used as feedstock. The coatings were fabricated by the HVOF spray process

The Weight of Identification What is light weight to the touch of a hand, but those who bear it around their neck feel the ultimate mass and value carried behind it? It is made up of a ball bearing chain that connects to another smaller chain holding a pair of two-inch by 1 and 1/8 inch engraved metal plates. They make a very distinctive metal sound over the heart when the human body is in motion. Engraved upon these metal plates is someones name, followed by their blood type, social security number
