ABSTRACT Elaeis guineensis is a species of palm generally called African oil palm, and it can reach the height of 20 m or more at maturity. The oil palm is major importance in Africa as a multi-purpose tree where it supplies medicines, foods and many other products to the local population. Elaeis guineensis is rapidly becoming one of the world's most planted plants, being grown especially for its oil-bearing seeds and fruits. Usually 23 kg is the average weight of each bunch but a bunch may up…

Alzheimer 's disease. In 1999 the Alzheimer 's vaccine is announced successful in mice. By infusing transgenic "Alzheimer" mice with beta-amyloid keeps the animals from creating plaques and other Alzheimer-like mind changes. Beta-amyloid is the main component of Alzheimer 's brain plaques as well as a prime suspect in activating nerve cell deterioration. From 2010 up until now agendas have been set nationally to try and put an end to the epidemic. Early symptoms of dementia can be mild and…

Introduction The Central Nervous System (CNS) has been considered devoid of lymphatic vasculature, and for years, the theory of the nonexistence of the lymphatic system in the brain has been accepted as a biological/anatomical fact. This very basic fact of neuro-anatomy has recently been upset by two independent studies, revealing that the brain does, in fact, have a functional lymphatic system. Although this study was originally done on mice brains, there have been similar findings in human…

Sarah Di Lello Mr. Jordan Bible 12B April 3, 2018 Creation vs Evolution The debate on creation versus evolution is one that will never end and never be won as long as we exist. The best we can do is discuss, not to win the argument, but to win over people. Our goal as Christians is to be stewards of Christ, being His vessels to spread His Word to change souls, not to win arguments and lose the people He loves. However, there are many pieces of evidence that solidify the reliability and authority…

Terracotta Warriors With the discovery of the terracotta army near Xi’an in China, we can learn many things pertaining to the culture of Ancient China and the Qin Dynasty. What we can achieve to learn is how the soldiers and weapons were crafted and the types of weaponry used. The technology used to create them was the best of it’s time, and shows the technological prowess of the Qin Dynasty. The level of organization is also extremely high, considering the process of making and relocating the…

who made the discovery and named them. He was able to take photographs and was the first to truly understand and explain what nanotubes actually are. Iijima discovery came when he placed samples of carbon containing Bucky balls in an electron microscope, but while taking photographs he notices strange thin cylinder like structures. Where Bucky balls have a spherical shape, nanotubes are…

unique composition and purity of as-deposited SnS2 thin films prepared with different precursor solution volumes from 5 ml to 25ml were determined by EDX analysis as shown in fig 5, which brought out the presence of Tin and Sulfur as elementary components. Two different peaks were observed in the spectrums from fig 5 relevant to the tin and sulfur. The EDX spectra show that the weight percentage for the film prepared at the precursor solution volume of 5 ml is 36.8% and 63.2%, which is…

ABSTRACT The reactivity of acid base cements forming hydroxyapatite (HA) such as, β-tricalcium phosphate (β-TCP) and dicalcium phosphate dehydrate (DCPD). Amorphous calcium phosphates, prepared by precipitation from supersaturated solutions, can also react to form apatitic cements since they are thermodynamic unstable with respect to HA and have a setting reaction more independent of particle size. Calcium phosphate cement containing an antibiotic can be used for filling bone defects and to…

Introduction In April 1997, Ellen DeGeneres came out as gay on national television during an episode of her sitcom. She pioneered the way for gay and lesbian representation in public television. At first, the feedback was good and viewers were supportive, then the criticism of Ellen’s new lifestyle grew and the show ended up getting canceled after the last episode of the season. A year later in September 1998, a new gay character emerged on the popular sitcom, Will and Grace. Will Truman was the…

Chapter 1 Introduction Waste generated from food industries is a source of an untapped energy which is mostly dumped inland fills whereby it releases greenhouse gases into the atmosphere. It is very difficult to treat and recycle food waste due to its composition. Food industry produces large volumes of wastes, both solids and liquid, resulting from the production, preparation and consumption of food. These wastes lead to increasing waste disposal and can pose severe pollution problems and…
