Mesquite is a controversial wood. You will most likely either really love its intense flavor and extremely hot flame or you will dislike the way it tends to overpower other flavors. As a hardwood, mesquite wood chips offer the density and dryness that you want from your smoking wood. The resin in woods can cause creosote to accumulate on food, which is why you want to smoke with seasoned hardwoods rather than green wood or softwoods. Grilling with mesquite originally became popular in…

Have you ever wondered why soda corrodes metals such as pennies, nails, etc.? How does it corrode them? One of the questions is if the soda does corrode the pennies how long will it take and why does it do it. It will take five days to fully corrode the pennies back to their shiny state, and will make them look brand new though they are probably a few years old. This test could get people to stop drinking soda which would lessen the risk of type 2 diabetes that can be caused by being overweight.…

For our diffusion experiment our group decided to work with salt water and gummy bears. Our experiment tested the weight of the gummy bears per salt dilutions. Our tests included 1g 2.5g 5g, 1.5g, and 10g of salt diluted with water. We knew that the higher the concentration of salt diluted into the water the heavier the diffused gummy bear would be, therefore we measure weight as our numerical data. My hypothesis was that the 10g dilution of salt would have the gummy bear with the largest…

Wow did you know that earth is depopulating in seconds because of deadly toxins and trash you helped spread. Every time you throw a piece of trash out of your car window or your hotel room that adds up and defeats the purpose of life and health. Cleaning earth will allow us to live a healthier life not forgetting a longer one as well. Plus it will also let Earth's existance last longer according to scientists ! WE need to stand up…

INTRODUCTION Cellular respiration is the breaking down of organic molecules by means of catabolic pathways that uses electron transport chain to produce ATP (Campbell 2011). ATP is used as energy in the synthesis of light or also known as Photosynthesis . ATP is used by photosynthetic organisms to produce their own food and also by performing cellular respiration. It needs mainly glucose and oxygen that involves the transfer of electrons in a chemical reaction. Cellular respiration is the…

1. Introduction Silicified wood is normally formed close to the surface due to the infiltration of buried wood with mineral-rich water and the associated deposition of minerals (Kim et al., 2009). Two typical geological environments have been reported, 1) trees transported by streams and rivers then buried in the fluvial sediments (e.g., Weibel, 1996; Fielding and Alexander, 2001; Parrish and Falcon-Lang, 2007; Hartmann et al., 2010), and 2) ash from volcanic eruptions buries trees while felled…

Yes, the sun has many positive effects on our lives but I am going to tell you some aspects you didn't know about the sun and how it can harm us in terrible ways. For example, cosmic and solar radiation are very bad for astronauts working in space to be exposed to, because they can get low blood count, radiation sickness’s, cataracts, melanoma, cancer… and potentially even death. Luckily their are a few scientific and natural solutions to prevent astronauts from being exposed to radiation from…

Tropical Cyclones Cameron Pillay Figure 1.1 Tropical cyclones. One of the wonders of nature that reassures us that god is watching our behavior. Jokes aside, hurricanes, typhoons, cyclones or even willie willies, whatever you prefer, are a massive danger to our society. The harsh winds and floods result in many deaths and major destruction to infrastructure along coastal regions(L. Dilley, J. Earle, K. Euston-Brown, G. Keats, A.Nxele, G. Ravenscroft, 2013). So how can we prepare ourselves?…

3.1. Types of solar cells There are 3 main types of commercially available cells: 3.1.1Mono crystalline Silicon PV& Polycrystalline Silicon PV The occupational health issues are associated to chemical burns and inhalation of fumes from hydro fluoric acid (HF) and other solutions of acids (e.g., HNO3) and alkalis (e.g., NaOH) used for cleaning wafers ,removing complete oxide layer, and cleaning the reactor. Performing the slicing of wafers also results in solid waste for example (e.g.,…

Climate change is one of the greatest threats facing humanity in the 21st century. As global patterns of temperature, rainfall and weather events change, the delicate balance of climate and life on earth is disrupted. The imbalance in climatic patterns poses serious threats to human health, biodiversity, human livelihoods, global economy, water resources and agriculture. Developing countries especially in Africa are more vulnerable to the impacts of climate change than countries in the developed…
