CHAPTER TWO RESULTS AND DISCUSSION 2.1 Synthesis of 1,3-butadienes Dienes can be synthesised from aldehydes and ketones using the Wittig reaction. The Wittig reaction facilitates the synthesis of new carbon-carbon double bonds at specific locations in aldehydes and ketones (Bernard & Ford, 1983). The overall reaction mechanism is shown in Figure 1. Protocols for synthesising 1,3-butadienes from aldehydes and ketones have been established in the literature. The synthesis protocol proposed by

How sugars affect our brain? After reading the book which is about neuroscience: The Brain what wrote by David Eagleman, I learned that our brain can help us adapt to any environment; build our interests and personality and works as the core of our body. In contrast, the book, however tells that external factors can also affect our brain’s operation: people, events or substance can change our personality and character through our brain. For instance, person who suffered sexual harassment will easy

Synthesis, Thermolysis, Photolysis and Animicrobial Evaluation of some Novel Semicarbazones and Thiosemicarbazones Derived from 3-Methyl-2-benzothiazolinone Hydrazone. Hisham Abdallah A. Yosef * and Nabila M. Ibrahim Department of Organometallic and Organometalloid Chemistry, National Research Centre, El-Behouth Street, P.O. 12622, Dokki, Giza, Egypt. Abstract: Reaction of 3-Methyl-2-benzithiazolinone hydrazone (1) with some seleceted isocyanate and isothiocyanate reagents 2a−j gave the respective

It is a complex disease which is characterized by an accumulation of β-amyloid (Aβ) plaques and neurofibrillary tangles composed of tau amyloid fibrils

Quantum Computing Less than 100 years ago, beginnings of the “new quantum theory” began. Only about 55 years after the new quantum theory began to emerge the idea that quantum phenomena can be used to perform computations. The idea being for a quantum computer was that classical computers would take an extremely long time to perform huge calculations, when a simple quantum system perform these same calculations all the time. One property that quantum computers have been observed to have was the

One of the principal problems for defining and diagnosing concussion, is that there is not a universally acceptable definition for concussion. In the article, the author refers to concussion as a “mild traumatic brain injury (MTBI) that results in a temporary loss of neurologic function without apparent structural damage, and may or may not involve loss of consciousness (LOC)” (Mennella, 2016). Concussions are considered a great concern in healthcare because according to the Center for Diseases

medical specialists who use radioactive instruments and x-rays to diagnose and make treatment decisions regarding health problems. They examine various types of images including x-rays, computer tomography (CT scans), mammograms ultrasounds, and magnetic resonance imaging scans (MRI). Radiologists are skilled in operating machinery, monitoring imaging sessions, recommending courses of treatment, administering nuclear medications, examining patients, recording medical treatments, and

methods to be discussed include magnetic resonance imaging (MRI), electroencephalogram (EEG) and positron emission tomography (PET). Amnesia is the loss or partial loss of a large area of memories often caused by a sudden brain injury or shock. (Eysenck, 2004). Amnesia caused by trauma is often temporary but can be permanent loss of an area of memory. An MRI is a way in which brain functions can be studied. This method creates images of the brain using a strong magnetic field and is often used by psychologists

How Technology is Benefiting Society Today On average, one household has at least five internet-connected devices, with 6% having fifteen or more. Technology is everywhere in the world today and society relies on it for many reasons that better life. The fast growth of technology now has been advancing life more efficiently. While technology may provide some concerns, the pros outweigh the cons. Two important ways technology helps society are by improving education and creating more tools to help

The products of Suzuki–Miyaura coupling reaction were characterized by nuclear magnetic resonance spectroscopy (NMR, model 500 MHz, Varian NMR Systems). Detailed information regarding the 1H NMR (500 MHz) and 13C NMR (125 MHz) NMR data are provided in the Supplementary Data. The NMR spectra were referenced to TMS as an internal standard and are reported as follows: chemical shift multiplicity (s = singlet, d = doublet, t = triplet, m = multiplet), coupling constant in Hz, and integration.
