The purpose of this project was originally to find ways of increasing the amount of green spaces in cities such as London. In areas like this many buildings are packed densely into little space which does not allow for many green areas, so green roofs seemed a sensible solution to this problem. From experiments we conducted we found that green roofs also absorb a substantial amount of water at one time and could provide a solution to flooding in cities. Based on these results we decided to look into this further by looking at the different materials that could be used as substrates and what effect each material has on the amount of water that is absorbed.
The field of archaeology has a multitude of facets, which intertwine social studies and the sciences. One of its subfields, geoarchaeology, places special emphasis on interdisciplinary work. It examines the way in which the landscape and climate of a region affected human’s lives, from trade to culture, using geophysical techniques. This paves the way for
ABSTRACT The Manhattan Project is the name of an infamous research project carried out during the second World War. It led to the creation of the atomic bomb and is an important part of scientific history. The advent of nuclear weaponry and the subsequent fear of a war involving such weapons is a frightening thought.
Introduction Willard Libby, a professor of chemistry at the University of Chicago, was awarded the Nobel Prize in Chemistry in the year 1960. This Nobel Prize was for the discovery of a technique, Radiocarbon Dating, that revolutionized the field of archaeology and palaeontology1. Radiocarbon Dating is a method used to estimate the age of carbon-containing

Alongside the global push to transition from non-renewable to renewable energy sources, there also exists a need to improve energy
Constructing an ROV that can operate underwater to collect the golf balls that are littering ponds all over the world will benefit the environment that is being poisoned as the golf balls decompose. It will offer a much safer method of extraction than diving for the gold balls because humans will not come into direct contact with the toxins and animals present in the water. During the construction we decided to use a 3D printer to print the wheels and scoop. We had to connect and make waterproof the motor’s wires to give more power to the ROV and we used PVC pipe to construct the body to provide buoyancy. During the construction and testing phase we encountered many setbacks. Because of our strict timeline and these unforeseen complications, we were not able to make the necessary adjustments to the ROV for it to be operational in a realistic setting.
Preliminary Evidence: The Impact of Contingency Management on Depression and Anxiety Among Crack Cocaine Dependent Patients in Brazil
Recently an epidemic has occurred in São Paulo, Brazil’s largest city of over 11 million people, where in an inner city community known as “Crackloandia”, hundreds of people are openly using crack cocaine. The purpose of this research was to examine the effect of the treatment method known as contingency management (CM) paired with standard treatment (STCM) to see whether or not this treatment would alter depression and or anxiety in the population. It was hypothesized that CM would lessen the severity of anxiety and depression in the population while they received treatment for their crack cocaine use as a secondary, indirect effect. All data for the clinical trial was collected from 45 individuals seeking treatment for crack cocaine use disorder. This study found that CM effectively reduces depression and anxiety scores in patients who abuse crack cocaine. The implications of this research find it likely that CM is a treatment option capable of treating patients with a comorbidity of anxiety, depression, and substance abuse disorders.
