Rising Temperatures and Surface Mass Loss in Greenland: Implications for Regional Glacier Dynamics and Global Sea Level Rise
Abstract: In Greenland, the ice sheet serves as one of the strongest indicators of global climate change, with consistently rising temperatures driving it toward an even more negative mass balance. Over the last two decades, warmer conditions have exacerbated surface melting, darkened ice, and resulted in feedback stimulating further loss. This study assesses how those temperature trends—particularly during summer peak months—have impacted the stability of Greenland's ice, and then, more importantly, …

Analysis of Tall Structures for Different Stiffness Ratios of Columns to Shear Walls and Column Shortening
Abstract: Differential axial shortening in a structure causes axial force redistribution among columns and walls, and introduces additional forces in the horizontal members such as beams and slab. Hence, it needs to be considered in the design, especially for medium to high-rise buildings. The best way to illustrate differential column shortening is to conduct floor-by-floor analysis, generally known as construction sequence analysis. Commercial software ETABS is available for conducting sequential analysis. …

A Conceptual Framework of Financial Risks Activated by Geo-Environmental Factors in Transportation Infrastructure Projects
Abstract: Geo-environmental factors wield substantial influence in both the design and construction of transportation infrastructure.Managing the financial risk associated with geo-environmental factors is key to the successful implementation of transportation infrastructure projects. Ground Investigations are the primary avenue to minimize financial risk due to geo-environmental factors. Limiting ground investigations to desk studies and preliminary reconnaissance based on superficial site inspection, or carrying out reactive post-contract ground investigations, however, appears to be …

Obsessive-Compulsive Disorder and Marijuana
Abstract: Obsessive-compulsive disorder (OCD) has both negative and positive attributes. Those with OCD find themselves genetically endowed with traits that will help them succeed in life--creativity, a sense of detail/symmetry, tenacious motivation, and a propensity for achievement in the arts, writing, and education. Without one major caveat though, OCD would be a strong quality for general success--the life of one with OCD may be overly complex and mentally tortuous. In this …

Indirect Methods for Discretizing Fractional Order Differentiator in Delta Domain—A Comparative Study
Abstract: In this paper, three indirect methods are presented for discretizing fractional order differentiator in delta domain. To this aim, three extensively used discrete time approximation methods of -domains are reformulated in delta domain. As a first step of applying the indirect discretization method, rational approximation of a half order differentiator is obtained using the Oustaloup approximation method. Then, all of the proposed discretization methods are applied separately on the integer …

Psychoactive and Physiological Homogeneity of Cannabis: A Literature Review: Actions of the Medical Plant that Takes Care of Itself
Abstract: Naturally occurring plants like Cannabis and the biologically ubiquitous alkaloids (e.g., morphine, quinine, and atropine) are composed of mostly physiological and psychoactive compounds. Extracts of the Cannabis plant are not alkaloid substances nor are they not related chemically to alkaloids, having no component nitrogen in their structures. Three species of Cannabis (marijuana) are recognized in scientific classifications: Cannabis sativa, Cannabis indicus and Cannabis ruderalis. Cannabis sativa is the species that …

CONVERSION BETWEEN T-π OF NETWORKS USING PSPICE CIRCUIT SIMULATION
Abstract: Any passive network can be represented by their equivalent in either T-π (star-delta)model. From the conversion methods of T-π (star-delta) for resistive circuits, the behavioural modeling of Pspice simulation program, in which various mathematical equations could be represented by non-linear voltage/current dependent sources, is used to obtain equivalent circuits using DC option. The resistors are represented by their linear voltage/current relation. The zero voltage sources are used to measure currents …
