Atomic Force Microscope

This paper summarizes, and reviews the three articles with a focus on how the authors were successful in achieving what was intended. In the first article, by Anshu Bagga, Mathur, Geoge, Monty Reichert, and Tuskey, experimental design and the quantitative method techniques were employed in conducting research. They made use of quantitative method in justifying their findings. In trying to establish how force transmission in endothelial cells is achieved, for instance, the authors utilized the Atomic Force and the Total Internal Reflection Fluorescence microscopy. The authors did this by mounting a bioscope AFM on an inverted microscope. Then they contacted an experiment for Variable-angle TIRFM. This was meant to help calibrate the coupling angle using the depth of penetration of the evanescent wave. They collected the set of force curves on the whole cell surface to help them in measuring the cellular mechanical properties. Using the linear regression fit for the force indentation curves, they were able to find the elastic modulus for the nuclear, cell body that was in proximity to the nucleus, and for the cell body that was near the edge. ...

Structural members in concrete bridges and highway
It is evident from the study that there are many elements that have to be understood before the structure of any structure like a bridge or a whole highway can be comprehended. Engineering laws are always based on key elements. Some key elements of both the structures will be explained quite extensively along with the types of bridges which have these elements present in them. Various steps are under-taken for the completion of both, the bridge and a highway alike. A construction company has to set up its goals and designs even before the first brick is laid. The construction steps are…

Global Navigation System
The idea of a global setup for navigation and monitoring was conceived in around 1960s when feasibility studies were conducted for this purpose, and in late 1970s the setup was run practically. For first few years the operations were limited to military use and defense purposes while last decade of 20th century gave rise to commercial use of G.P.S. There are two more competitive forces in competition with NAVSTAR in this field, one run and administered by Russia called GLONASS, while Europeans have Galileo in place. The annual costs incurred in the working and maintenance of G.P.S is around…

Joining and Fastening Processes (Manufacturing Engineering Processes)
These engineering materials in their raw form are extracted from their ores. These raw materials from ores are transformed into molten form through refining and reducing processes. The molten material is process through molds to produce commercial or industrial castings called ingots. These ingots are then processed through rolling to transform these into billets, rods and slabs suitable for marketing. These materials then undergo various manufacturing processes to obtain useful products in diverse range of sizes, shapes and forms desired by end user. According to Singh, these manufacturing…

Such finite supplies necessitate current technology and development to be concentric upon finding alternate means of locomotion that service the needs of current and future human populations. One of the most relevant alternatives that currently exists within the field of transportation science is of course the prospect of the electric vehicle. Although the technology to produce such vehicles dates back to prior to the Second World War, it is only recently that the forces of environmental preservation, global warming, and the rising cost and ultimate limitations to fossil fuels have brought…
