Passengers Demand on Railway Transport in Tanzania A Case of Dar es Salaam to Moshi – Arusha Route

This paper presents mathematical model on the effect of parameters on passenger demand on the train transport from Dar es Salaam to Moshi - Arusha Route. Methodology: Numerical simulations were used to demonstrate the impact of parameters on passenger demand. Findings: The results shows that increase of extra effort of selling tickets and availability of transport to the train station and from the train station to the passengers’ destinations S, ratio of change of passenger demand and change of train capacity r, number of coaches with service improvement Ca will increase passenger demand.

Evaluation of energy Efficient Refurbishment of Residential Buildings in Southern Europe Based on the Cost-Optimal Methodology

In line with the European Energy Performance of Building Directive (EPBD), this paper aims to calculate the cost-optimal energy performance of a residential building in southern Europe, more precisely in Portugal, taking into consideration thermal and lighting (daylighting and artificial lighting) refurbishment solutions. The economic calculation method used considers the initial investment costs, the running costs (including annual maintenance costs, operational costs, energy costs and periodic replacement costs), greenhouse gas emissions costs and disposal costs.

Abdominal adiposity evaluated by two anthropometric pairs and its relationship with cardiovascular risk

Introduction: Obesity is a risk factor, with abdominal adiposity being responsible for most cases of cardiovascular diseases. Objective: To evaluate abdominal adiposity using two anthropometric parameters and its relationship with cardiovascular risk in adolescents. Methods: Cross-sectional, quantitative study, with 575 adolescents aged 15 to 19, from public schools in Campina Grande-PB, Brazil. Cardiovascular risk was assessed using the Pathobiological Determinants of Atherosclerosis in Youth score and abdominal adiposity was assessed using waist circumference and waist-to-height ratio.

The Carbon Footprint of Mega Sport Events: A Comparative study to Understand the Sustainability of Olympic Games

Research Purpose: In line with Paris Agreement, International Olympic Committee (IOC) has committed to reduce direct and indirect carbon emissions by 30% by 2024 and 50% by 2030. Mitigating the impacts of climate change and recognizing the importance of sustainability, the environmental impacts of mega sporting events must be attended seriously. Aim and Objective: The study aims toward a systematic evaluation for existence of sustainability to evaluate the sustainability of the last four Summer Olympics from 2012-2024.

IOT-Enabled Health Monitoring system: Design and Implementation for Enhanced Patient Care

Every year, many people lose their lives due to a delay in the timely identification of medical conditions and the assessment of their health status during emergency transfers to hospitals. This is especially true for elderly and infirm individuals who require continuous monitoring of their physiological parameters and surrounding environmental conditions. Unfortunately, such patients are often unable to visit the hospital frequently. To address these challenges, a web-centric patient health surveillance system has been developed.

Ethnobotanical inventory and evaluation of the dyeing potential of some species of Congolese Flora, sources of natural dyes among the Craftsmen of Brazzaville

Extracts from certain plants provide the colouring and binding matter for dyeing. The aim of this study of the dye plants used by craftsmen in the Congo is to characterise the chemical groups with dyeing potential. To achieve this, an ethnobotanical study based on interviews was used to identify the species used by Brazzaville artisans. The ethnobotanical survey of 56 artisans revealed that 38 plant species belonging to 26 botanical families provide various colours that can be used by these artisans.

Ashwagandha: The Hero Plant

Withaniasomnifera L. is a multipurpose medicinal plant of family Solanaceae occurring abundantly in sub-tropical regions of the world. W. somnifera is rich in numerous treasured secondary metabolites such as steroids, withanolidealkaloids, flavonoids, phenolics, saponins, and glycosides. In recent years, there has been a significant surge in reports on the health-promoting benefits of winter cherry also known as Ashwagandha. The present review states its potential use as neuroprotective, sedative, adaptogenic anti-inflammatory, antimicrobial, cardioprotective and anti-diabetic properties.
