Application of Reduced Differential Transform Method for Solving Nonlinear Reaction-Diffusion-Convection Problems
Get PDFIn this paper, Reduced differential transform method is presented for solving nonlinear reactiondiffusion- convection initial value problems. The methodology with some known techniques shows that the present approach is simple and effective.To show the efficiency of the present method, four interesting examples is given
On Calculation of Failure Probability for Structures Designed Based on Magnitudes of Historical Event
Get PDFDuring their operational life, structures may be subject to various types of live load caused by events such as earthquakes, high speed winds, etc. Given the design life of a structure, the probability for a specific live load to cause a failure depends on the magnitude of the load structure it is designed to withstand (designed load). In this article, methods are developed for calculation of the failure probability for structures designed to withstand loads comparable to historical loads at the site of interest
Drugs and drug control in jamaica
No full textJamaica is widely regarded as a beautiful destination given its mountainous terrains, beaches and tropical climate. It is the third largest island in the Caribbean Sea. In 1494, Christopher Columbus arrived in the island of Xamaica (from which “Jamaica” is derived). Initially occupied by the Arawaks and subsequently, in the early 1500s, by the Spaniards, the English gained control over the island in the mid-1700s. They remained in control until Jamaica\u27s independence from England on August 6, 1962. African slaves were brought in and their descendants remain the nation\u27s dominant ethnic group. Jamaica now has a population of 2.9 million people with more than 90% being Black, more than 6% mixed, and more than 2% of other ethnic groups or unknown (Central Intelligence Agency, 2013; July estimate). The official language is English, but the majority of the locals speak a dialect known as: Jamaican patois (which is a mix of English and African phonetic sounds). The island has a literacy rate of 87%, an unemployment rate of over 14%, a poverty rate of 16.5%, an inflation rate of 6.9% and a life expectancy of 73 years (Central Intelligence Agency, 2013). Christianity is the dominant religion. The Jamaican economy is heavily reliant on service industries, which represented over 60% of its gross domestic product (GDP) in 2011 (Central Intelligence Agency, 2013). The island\u27s foreign exchange, which gives an indication of a nation\u27s economic health and the overall welfare of its people, comes largely from bauxite, tourism, and remittances (ibid.). Proudly, however, many Jamaicans refer to their country as “likkle but tallawah” (meaning small but mighty) in reference to Jamaicans’ ability to not only compete with persons from more developed countries, but to outperform on the world stage as evidenced by the exportation of its culture, the popularity of reggae music, and athletic talents like legendary sprinter Usain Bolt
Sustainable campus improvement program design using energy efficiency and conservation
No full textReducing energy consumption is critical to improving campus sustainability. Both increased efficiency of built infrastructure and conservation by users can contribute. This work investigates feedback in the design of energy improvement programs that exploit both efficiency and conservation by developing a system dynamics model. The model formalizes the paid-from-savings approach and is validated using a sustainability program at a major university. Model simulations use five program designs, two forms of performance (energy savings and monetary savings), and capital requirements to test four hypotheses. This research indicated the existence of a trade-off space of program designs in which the preferred design will depend upon specific objectives. Other conclusions partially support improved performance with more investment and recommend the use of conservation to fund efficiency under capital constraints. A feedback analysis provides a richer explanation of the drivers of program success. The scientific contributions include an improved understanding of campus sustainability improvement program design, a formal dynamic model for program design, and an innovative staged design as an advanced solution to the dynamic challenges of designing campus sustainability improvement programs
Impulsivity and Reasons for Living Among African American Youth: A Risk-Protection Framework of Suicidal Ideation
No full textThis study aims to explore the impact of specific facets of impulsivity as measured by the UPPS Impulsive Behavior Scale (UPPS), as well as reasons for living in predicting suicidal ideation among African American college-aged students. The incremental validity of each facet of the UPPS interacting with reasons for living, a construct meant to buffer against risk for suicide, was explored in a sample of African American students (N = 130; ages 18–24). Results revealed significant interactions between reasons for living and two factors of impulsivity, (lack of) premeditation and sensation seeking. Higher levels of sensation seeking and lack of premeditation in conjunction with lower reasons for living was associated with increased suicidal ideation. Neither urgency nor (lack of) perseverance significantly interacted with reasons for living in association with suicidal ideation. These results suggest including elements of impulsivity, specifically sensation seeking and (lack of) premeditation, when screening for suicidal ideation among African American youth. Future investigations should continue to integrate factors of both risk and protection when determining risk for suicide

Potential role of Property Management in Green Building rating tool in Malaysia: A preliminary study
No full textSustainable Development (SD) concepts yet to adapt the development aspects as outlined in Property Management (PM). The effectiveness and success of SD covers for Green Building (GB), Carbon Emission (CE) and Energy Saving (ES) are still in rare and open for argument. In Malaysia, Architect\u27s Association of Malaysia (PAM) had developed and works it out over the years towards for more sustainable and green architecture (including buildings). The need for a localized green building rating tool (GBRT) became more evident by 2008. This is in the light especially increasing demand from building end-users for Green Rated Buildings (GRB) that would not overly and adversely contribute to the destruction of the environment. This is also in-line with the objectives to practice a good Corporate Social Responsibility (CSR) to support environmental friendly initiatives including within their office premises. For that, PAM Council endorsed and approved the formation of the new Sustainability Committee, in August 2008, who was tasked primarily to develop and set-up the GBRT become first tropical green tool, known as Green Building Index (GBI). Singapore\u27s Green Mark had practicing mandatory rules for minimum Certified Rating to all new buildings or works on existing buildings exceeding floor area 2,000 m2 starting from 2005. Thus, this study will investigate the existence of gap between the set of guidelines in GB and the actual implementation in accordance to PM practices in Malaysia. The aim of this paper is to relate the economical value of properties as well as the demand of properties with excellent environmental concern through GB. Interview and setting for case study become a mechanism to strengthen is research. The expected findings cover for efficiency of PM in GB concepts
