In this article, we focus on some notions of prime submod- ules over a commutative ring with identity. Suppose R is a commutative ring with identity and M is an R-module. A proper submodule N of M is called prime if rm is element of N implies r element of (N : M) or m element of N. In this article we give a generalized version of prime submodule in its localization which named as S(N)-almost prime submodule. This generalization was obtained by creating generalized version of almost prime submodule such that the submodule is not al- most prime but its localization is almost prime. Furthermore, some characterizations of S(N)-almost prime submodules and its relation to S(I)-almost prime ideals are given in this article.
Change and Continuity in the Political Attitudes of Canadian University Students, 1986-2011

While Political Science is taught at nearly every university in Canada, little is known about the political attitudes of the Canadian students actually taking courses in the discipline. Beyond anecdotal evidence based largely on personal impressions, there has been no other indicator to gauge our students’ political dispositions and preferences, especially over an extended period of time. We shed some light on this issue by presenting the findings of a survey of first-year students taking an introductory course in Political Science at [name withheld for blind review]. Spanning over 25 years from 1986 to 2011, the survey and its findings provide a useful window into the evolving pattern of political attitudes among our first-year students, which include, among others: ideological inclinations, both self-identified and more objectively measured; party preferences; views on Quebec separatism; support for Canada’s international activism; attitudes toward the US; and assessment of international economic openness.
Chondroid metaplasia of paraspinal connective tissue in the degenerative spine

A 51-year-old male was routinely biopsied during a paraspinal muscle study. The biopsy sample was taken from the right erector spinae muscle at the fourth lumbar vertebra. The patient had no history of (diagnosed) major back trauma. The obtained sample was histologically analyzed (hematoxylin and eosin, safranin O), and complementary magnetic resonance imaging was performed. The biopsied sample contained chondroid tissue. Based on its location, the biopsy sample was appointed as chondroid metaplasia. Although chondroid metaplasia is not uncommon in humans, this is the first report of chondroid metaplasia within the paraspinal connective tissue. We propose a novel mechanism to explain the paraspinal chrondrogenic changes, related to spinal degeneration.

PT. Nusahadi Citraharmonis is a leading manufacturing company in Indonesia that produces spare parts for various automotive industries. The company is an active supplier for several well-known car manufacturer in Indonesia, which are: NTC, HMMI, TMMIN, and ASKA. However, the company is currently having difficulty in fulfilling all customer demand on time. Thus, creating backlogged order in the system and decreasing the daily total complete shipment. The objective of this research is to redesign new inventory level to increase the daily total complete shipment. To solve the problem, Define-Measure-Analyze-Improve-Control (DMAIC) is used as the procedure, cause effect analysis is used as a tool to identify the key factors affecting daily total complete shipment, and system dynamics simulation is used as a tool to redesign inventory level. From the result of system dynamics simulation, the newly redesigned inventory level is able to decrease the backlogged order in the system and increase the daily total complete shipment. Besides the system dynamics simulation, standard operating procedure for operating the system is also made and given to the company for future use.

Sensors have become inseparable components in designing control systems, but performance is often degraded by noise from the environment or system. In this paper, the performance of a gyroscope and accelerometer on a flapping wing micro aerial vehicle (FW-MAV) was studied. The effect of a flapping wing on the sensors was observed. The benefit of using a mechanical damper or foam were also compared. The vibration generated by the flapping motion caused the accelerometer to suffer rectification errors, leading to bias or offset shifts in the measurement. Common filtering methods, such as low pass filters and complementary or Kalman filters, are affected by this problem. This study demonstrates that the use of foam can reduce the rectification error significantly.
