New Recurrence Relations for Tribonacci Sequence and Generalized Tribonacci Sequence
Abstract: AbstractTribonacci numbers are placed on the corners of polygons clockwise with each corner receiving a term. Then, it is argued whether there is a relationship among the numbers in the same corners. It is shown to be able to find mth term corresponding to the corner Ak in an n-gon by a relation:where, is a Tribonaccisequence and is a Tribonacci- Lucas sequence. The relation is proved by using a binet …

Risk of Malnutrition and Its Association with Economic Maintenance in Inpatients Older Adults at a University-Affiliated Hospital
Abstract: The demographic aging has led to an increase in the prevalence of malnutrition. Malnutrition risk (MR) is considered as a multifactorial condition associated with an increased morbi-mortality in older adults. The association between MR and socioeconomic factors as the form of economic maintenance (EM) is not yet clear in aged population. However, an effective strategy for the diagnosis of MR is the comprehensive geriatric assessment (CGA). The aim of this …

Proposal of System for High Efficiency Energy Extraction from LNG and Study of Use of EGR and SCR System in Ships
Abstract: The paper focuses on the green shipping methodologies and environment friendly practices. Liquefied natural gas (LNG) is one of the most effective alternatives to traditional shipping fuels. Ports have LNG re-gasification systems, which generally use Open Rack Vaporizers (ORVs) to convert the LNG to NG. In this process, a lot of the ‘cold energy’ is lost. A proposal for a LNG re-gasification system has been made in this paper which …
