    In 2009, the last climate change conference in Copenhagen, countries were not able to find a solution to climate change. Back then climate change was not addressed as seriously as it will be in the next climate change conference. Many countries have realized the potential consequences of climate change and have already began looking for solutions. However, to defeat climate change, it cannot be a few countries trying to look for solutions. It has the be a collective effort by each country in the…

    Hydroxyapatite (HA) has been studied for their excellent performances which are suitable for use in bone defects or regeneration of bone. Hydroxyapatite (HA) has poor mechanical properties which make it limited used in a load bearing area. In this case, sodium alginate (SA) was used to be mixed with hydroxyapatite (HA) by using precipitation method to increase the mechanical and physical properties. The mixing of hydroxyapatite/sodium alginate effectively increases the densification and hardness…

    The polyurethane segments show high intersegment attraction such as hydrogen bonding and may be able to crystallize and form hard segments. In such polymers hard segments with Tg well above normal ambient temperature are separated by polyol soft segments, which in the mass are rubbery in nature. Hard and soft segments are arranged alternate along the polymer chain. Fig.7. Polyurethane chain configuration [32] 4.2.2. Polyurethane properties and advantages for product development…

    Introduction Microbes are essential to everyday life. Going from the basic food we eat to biogeochemical cycles, if we didn 't have biogeochemical cycles we would no longer have any of the resources that we have now; for example, there is plenty of nitrogen in the atmosphere but it 's all not available until it has been fixed, and that is when the microbes come in and changes the nitrogen in a way that is usable. Humans come in contact with microbes every day there is never a time there are…

    active metal is anodic to a more metallic element. Metal at an elevated temperature becomes anodic to identical metal at a lower temperature. Generally, as temperature will increase, corrosion increases. However, this relies on the availability of oxygen. Since elevated temperature makes a metal more active, it will become anodic for rest of the metal. So an electrochemical corrosion cell might cause fast corrosion on metals that are at elevated temperatures. 2) pH of the Electrolyte The ph of…

    Deforestation in the Amazon: Impact On Humans Trees are often looked upon as everyday objects that will be around forever. However, at the rate they are being cut down, that may not be the case. The process of clearing trees and transforming a forest into cleared land is called deforestation (Deforestation, n.d). This process is occurring all over the planet, specifically the Amazon Forest, leaving an immeasurably large impact not only on the Earth but human life as well. Trees make up the…

    INTRODUCTION Chemically and thermodynamically foam is an unstable, dispersed system of entrapment of gaseous molecules in solid or liquid matter. Instability of foam is caused generally due to coalescence, liquid drainage and disproportion of bubbles. Foam being aqueous system can be produced using surfactants available commercially. The types of surfactants used in preparation of aqueous foam influence the foam properties (Eisner et al., 2007; Bhakta and Ruckenstein, 1995). Successful foam…
