Design And Implementation Of Cardiopulmonary Resuscitation Simulation Model, Mbazingwa Mkiramweni Dec 2022

Design And Implementation Of Cardiopulmonary Resuscitation Simulation Model, Mbazingwa Mkiramweni

Tanzania Journal of Engineering and Technology (TJET)

Cardiopulmonary resuscitation (CPR) is a life-saving procedure that can multiply a person's chances of survival after a cardiac arrest. The effectiveness of CPR procedures is heavily influenced by the individual skills of the rescuer providing assistance. Chest compressions delivered at an appropriate depth and rate, allowing full chest recoil and with minimal interruptions, are critical for improving cardiac arrest survival. The lack of quality CPR training models in developing countries has a significant impact on the quality of CPR training and skills acquired. Therefore, in this paper, we aim at improving CPR training by designing a high-fidelity CPR training manikin. …

Synthesis, Characterisation And Catalytic Evaluation Of Castor Oil-Templated Mesoporous Sulfated Solid Acid Catalysts For Esterification Reaction, Steven Nyandoro Pr

Tanzania Journal of Engineering and Technology (TJET)

In bio-refinery and other catalytic reactions, heterogeneous catalysts confer advantage over homogenous catalysts due to minimized recovery and separation costs. However, templating surfactant and solid support for the synthesis of heterogeneous catalysts ought to consider their cheap sources and environmentally friendliness for their sustainable use. Thus, with the vision to make the process significantly benign, in the present work, solid acids were synthesised from renewable sources (castor oil as surfactant and rice husk as the source of silica). The synthesised castor oil-templated mesoporous sulfonic acid modified catalysts (SO3H-MTS and SO3H-MT-RHS) were characterised and evaluated for catalytic esterification of acetic acid …

Angiogenic Supports For Microvascular Engineering, Zain Siddiqui Dec 2022

Angiogenic Supports For Microvascular Engineering, Zain Siddiqui

Dissertations

Ischemic tissue disease is caused by a lack of circulation / blood supply to tissue. This can be treated by introducing a number of angiogenic (pro-blood vessel forming) factors into the tissue. This work presents strategies for ischemic tissue treatment utilizing a novel proangiogenic self-assembling peptide hydrogel platform. To demonstrate the utility of this platform, its use alone as an angiogenic therapeutic (both alone as a self-assembling hydrogel and with two-component systems), and its ability to vascularize implants is explored. Due to these angiogenic scaffolds demonstrating efficacy to regenerate microvasculature, this work evaluates diseases that can be treated by the …

Nondirect Line-Of-Sight Free-Space Optical Communications And Networks, Paa Kwesi Affir Esubonteng Dec 2022

Nondirect Line-Of-Sight Free-Space Optical Communications And Networks, Paa Kwesi Affir Esubonteng

Dissertations

Nondirect Line-of-Sight Free-Space Optical Communications (NLoS-FSOC) uses diffuse reflected light to establish communication between two or more stations that are with or without line-of-sight (LoS) to each other. Different from free-space optical communications (FSOC), NLoS-FSOC uses a diffuse reflector (DR) between a transmitter and a receiver so that LoS is not required between them but between the station and the DR. Unlike a mirror, the DR reflects the incident light to all directions and except to itself. That multidirectional reflection broadcast the optical transmission to all receivers with LoS to the DR. The optical broadcast channel establishes a true optical …


Naturally Derived Fibrous Scaffolds Containing Metabolic Factors For Bone Tissue Engineering, Apurva Limaye Dec 2022

Naturally Derived Fibrous Scaffolds Containing Metabolic Factors For Bone Tissue Engineering, Apurva Limaye

Dissertations

More than 500,000 bone grafting procedures are performed each year to treat bone defects, trauma, and non-unions. Current strategies, including autografts and allografts, face limitations that include donor site morbidity and poor integration, respectively. Treatments using the delivery of the growth factor, bone morphogenetic protein-2 (BMP2), result in ectopic bone formation and adverse effects at high doses. Tissue engineering strategies are utilized to combat these challenges. Natural biomaterials are commonly used as tissue engineering scaffolds due to their biocompatibility, biodegradability, and they can promote cellular function. However, animal-derived materials can have limitations in availability, lot to lot variability and potential …

Recent Trends In Mineral Processing Based On Density And Particle Size–A Review, Ahmed Sobhy Dec 2022

Recent Trends In Mineral Processing Based On Density And Particle Size–A Review, Ahmed Sobhy

Mining Engineering Faculty Research & Creative Works

Most mineral beneficiation development in the world focus on size and density-based separation technologies. In recent years, ore size-based and density-based separation technologies have attracted more consideration to obtaining rough or final high-quality products. Due to the dissimilarity of physical properties like particle size and density, valuable and gangue minerals can be segregated via size-based and density-based separation technologies. Removing the impurities and recovering the target minerals are accomplished by size-based separation technologies alone or are usually followed by cleaning processes utilizing density-based separation abilities. The density variation among valuable and gangue minerals leads to dissimilarities in settling velocity in …

Preparation Of Azomethine Derivatives (Schif Bases) Chitosan Apis Mellifera, A S. Mengliev, G A. Ikhtiyarova

Technical science and innovation

Chitin and chitosan should be considered as derivatives of cellulose. The basis for such an approach to these polysaccharides is their chemical structure. The macromolecular chains of these polymers are formed by glucopyranose cycles, which, being connected by β- (1→4) glucosidic bonds, form linear polymer chains. The biological functions and mechanical properties of these polysaccharides are largely determined by the conformation of macromolecules and the distribution of reactive groups in them. Due to the unique properties of chitin and chitosan, they are becoming increasingly important in the practical and especially in the medical and biological activities of mankind. The aim …

Intelligent Approach To Power System Management During Well Drilling In Terms Of Environmental Impact, N N. Makhmudov, K M. Sulitanofu

Technical science and innovation

An autonomous hybrid power system is an intelligent power installation that provides electricity to isolated consumers without being connected to the power grid. The introduction of autonomous hybrid power systems in the oil and gas industry is considered as an option to improve energy and environmental security. As a rule, oil and gas fields are located remotely and off the grid, and therefore electricity is generated using diesel generators. This article discusses the possibility of reducing emissions of pollutants into the atmosphere by using an autonomous hybrid installation as a source of electrical energy.

Research outputs 2022 to 2026

Solar irradiance forecasting is a major priority for the power transmission systems in order to generate and incorporate the performance of massive photovoltaic plants efficiently. As such, prior forecasting techniques that use classical modelling and single deep learning models that undertake feature extraction procedures manually were unable to meet the output demands in specific situations with dynamic variability. Therefore, in this study, we propose an efficient novel hybrid solar irradiance forecasting model based on three steps. In the first step, we employ a powerful variable input selection strategy named as partial mutual information (PMI) to calculate the linear and non-linear …
