Science has come a long way since its surge from the Renaissance, a time of discovery and acceptance of new scientific practices. Biology, a science concerning life structures, has made very pronounced advancements. From subduing the black plague with sanitation to restarting hearts shortly after it seizes, it seems that there is no limit to what can be accomplished now in the 21st century. Creation of life has been a debated subject recently. The science and advancements we've made leave us…

The components of the lithium ion batteries include a positive electrode made of metal oxide, negative electrode made of carbon (graphite), a separator made of a micro-porous polymer, and an organic electrolyte (ether) that is made up of dissolved ions of lithium. During recharge, the lithium ions travel from the positive metal oxide to the negatively charged graphite electrode. The reverse flow occurs during discharge (when the battery is in use) (Carnegie, 40; Divya and Østergaard, 513).…

Fish have a unique position with respect to their taxonomic and phylogenic status among vertebrates and occupy an important place in vertebrate’s genealogy. Most fish are ectothermic ("cold-blooded"), allowing their body temperatures to vary (1 – 2 ºC) as ambient temperatures change. Majority of siluroid fish are economically important for human consumption. Protein and vitamins content in fish flesh varies from high to moderate and make it as rich source of protein diet. Fishes of siluroid…

of times shorter than the wavelengths of visible light electron microscope can show much greater detail than optical microscopes. Electron microscopy has led to advancements in very many areas of scientific research such as structural biology, nanotechnology, forensics, pharmacology…

1.0 HISTORICAL DEVELOPMENT OF ENGINEERING Science and Engineering can be a regarded as an inseparable concept to which modern engineering depends. Engineering was first practiced from man’s mental capacity that fashioned him into recognizing tools and natural resources around him and developing on that for his own benefit. Take for example “the prehistoric man” where discoveries were made of tools used, knowledge of fire depicted by drawings in caves, all without the understanding of science…

4.3. Niosomes: Niosomes were developed and patented by L'Oréal in the 1970s and 80s. The first niosomal formulation was introduced by Lancome in 1987 and have been widely applied in pharmaceutics as a demanding tool to improve the delivery of many drugs34. Niosomes are vesicles formed by self-assembly of hydrated and synthetic non-ionic surfactants e.g sorbitans (Spans) or polysorbates (Tweens). Non-ionic surfactants are inexpensive, non-toxic, and can be found in wide variety. Types of…

As indicated by Tuckman's theory, there are five phases of group advancement: forming, storming, norming, performing, and adjourning. Amid these stages bunch individuals must address a few issues and the route in which these issues are determined figures out if the gathering will succeed in finishing its assignments. Forming : This stage is generally described by some disarray and vulnerability. The real objectives of the group have not been set up. The way of the errand or administration of…

Fifty years ago, technology in the classroom was almost non-existent. Calculators did not come in popular use in the classrooms until 1970, with the handheld graphing calculator not coming onto the scene until 1985. Technology in the classroom has come a long way, but is it enough? As the use of students using technology outside of school increases, it is inevitable that schools are going to need to adapt, but rather or not this enhances education is still out in the open. Marc Prensky,…

The world of Artificial Intelligence offers profound benefits to society, along with perilous potential consequences. The outcome of the advancement of Artificial Intelligence likely lies in the hands of those who develop the field. This kind of power comes with numerous ethical questions, as to how far we as a society want to take Artificial Intelligence. Would we prefer a world without disease, or poverty, at the expense of human control over society itself? Important questions such as…

New way of teaching by iPad Many devices such as laptops and iPads are being used increasingly in education around the world. A journal research article “Teacher’s use of iPads in higher education” created by Daniel Churchill and Tianchong Wang in a famous book in Hong Kong Educational technology from page 214 to 225. Both authors are famous professors in Hong Kong who work the most popular Universities in Hong Kong, The Chinese University of Hong Kong. Both author study the approaching process…
