Strength of Adhesives in a Lap Joint

Strength of Adhesives in a lap joint Introduction             Shear force refers to any internal force which acts in a perpendicular direction on a substance to its extension. For example air pressure along an air plane wing (Krenk, 2007). Compression test involves a measuring instrument such as leak-down tester used in determining internal condition of combustion engines; it’s done by compressing air into the cylinder and recording the rate at which air is leaking out.eg testing the condition of racing…

My Future

In the future I see myself studying The Natural Science Program, hopefully with a friend through my years in High School. After school I want to study into becoming a doctor, probably in another country than Sweden, hopefully France, which will be interesting. It will probably take up a lot of my free time but it will be worth it in the end. I will probably study alongside a friend, having him as my roommate which hopefully will make my…

Wheel of Science

Around 1600 A. D. it became apparent to sever scientists such as Galileo, Frances bacon and Tycho Brahe that the deductive methods, “while wildly successful in mathematics, did not fit well with the scientific investigations of nature. ” (Inductive, 2004). To use the deductive method you must start with simple, true statements about the way the world works, then you build your logical system of nature based on these statements. If those statements are true, then it follows that everything…

Criminalistics_ an Introduction to Forensic Science

Generally, the techniques used in investigating crime should be reliable, accurate and evaluate every small detail in connection with the crime. As result, the investigators use the X- ray method which is used in the form of x- ray diffraction powder and it is highly used in a forensic laboratory (Saferstein, 2011). X-ray is an important method used to test both organic and inorganic substances. X- ray diffraction used for its many benefits in the laboratory for example the X-ray…

Fiber Optic Connector Assembly

The three fiber geometry parameters that have the greatest impact on splicing performance include the following: Cladding diameter—the outside diameter of the cladding glass region. core/clad concentricity (or core-to-cladding offset)—how well the core is centered in the cladding glass region fiber curl—the amount of curvature over a fixed length of fiber These parameters are determined and controlled during the fiber-manufacturing process. As fiber is cut and spliced according to system needs, it is important to be able to count on…

The Natural Science

Cosmology– Cosmology deals with things issues the origin and past history of the universe, its structure like the number and distribution of stars and galaxies, and even predictions of the future behavior of universe (Visser 2004). Theories of evolution of the universe “Cosmology cannot predict anything about the universe unless it makes some assumption about the initial conditions – Stephen Hawking” (Adams 2000) There are 3 theories put forward to explain the origin and evolution of universe: Big-Bang Theory– The…

Does Science Tells Us the Truth

In the American heritage Dictionary of the English Language, science has been defined as “the observation, identification, description, experimental investigation, and theoretical explanation of natural phenomenon” (Gottlieb, 1997). But can these explanations be equated to truth? Through out history, science has explained myriad occurrences in the universe. However, until today, many still questions the validity of scientific knowledge in relation to its truthfulness and the veracity of its claimed truthfulness. According to Gottlied (1997), science is “an intellectual activity…designed to…

Behavioral Ecology of Bees

Behavioral Ecology of Bees Introduction Abstract             Bees constitute one of the major plant pollinators globally. They experience adaptation for feeding on pollen and nectar. Pollination is as well defined as the process by which pollen grains are transferred between plants in reproduction. The amount of colonies (maintained by beekeepers) has gradually declined due to systematic use of pesticide, urbanization, Varroa mites, and tracheal. However, this has increased the competition of bee keeping for pollination purposes. Pollination refers to process…
