Preparation and Characterization of Pure Pla Filament and Pbat-Reinforced Pla Filament For Fdm 3d Printing /

By Naeem Ul Hassan. . 77p. , This study focuses on preparing pure polylactic acid (PLA) and polybutylene adipate –coterephthalate (PBAT)-reinforced PLA filaments. PLA and PBAT are biodegradable aliphatic polyesters and have recently received considerable attentions. Due to its brittle nature, PLA has limited application in various fields. To overcome this challenge, numerous efforts have been made to incorporate various additives to enhance its performance. In this work, pure PLA filament and PBAT-reinforced PLA filament with diameter 1.75 ± 0.02 mm were prepared in the lab. Their thermal and mechanical properties were analyzed and compared with the commercial PLA filament bought from the market. Following the previous research works and suggestions of incorporating no more than 10 wt.% PBAT, we have mixed 8 wt.% PBAT into the PLA mixture. We then proceeded to extrude pure PLA and PBAT-reinforced PLA filaments at a temperature range of 170 oC to 180 oC, utilizing single screw extruder. Next, we printed tensile and flexural specimens using an FDM 3D printer, in accordance with Taguchi L9 OA. Due to PBAT’s high ductility, 92-8 wt.% PLA-PBAT filament demonstrated a significant increase in elongation at break, reaching up to 12%. Likewise, the PLA-PBAT filament displayed tensile and flexural strengths of up to 48.34 MPa and 107.295 MPa respectively. These values are comparable to the tensile and flexural strengths of pure PLA, which is a great indication that the addition of 8 wt.% PBAT did not cause any unacceptable reduction in the tensile and flexural strengths. Additionally, it was found through DSC analysis that PLA-PBAT filament exhibited a higher degree of crystallinity (Xc) of up to 38.7%, which is significantly higher than that of pure extruded PLA. Furthermore, the TGA curve indicated that thermal stability of PLA-PBAT filament was improved by adding 8 wt.% PBAT. Moreover, digital microscopy results revealed that PLA-PBAT filament had a ductile fracture after necking, whereas pure PLA had a brittle fracture. Lastly, statistical analysis showed that both material type and layer thickness had significant impact on the results. The addition of this new PLA-PBAT filament provides an additional alternative to the current FDM filaments, and it will aid in reducing the constraints of the materials when it comes to additive manufacturing (AM) progress. 30cm.

Analysis of Adhesive Joints using Digital Image Correlation (DIC) /

By Farooq, Muhammad Kashif . . 83p. , In this study, the effect of cork particles on the failure behavior of SLJs was investigated experimentally through tensile testing and non-contact digital image correlation (DIC) methods. Cork particles within size range of 125-250 μm were added at 0, 0.25, 0.50, 0.75 and 1.0% wt. in a brittle epoxy. SLJs with and without cork particles were tested under a displacement control condition of 1.3 mm/min and digital images were captured during the deformation in order to analyze the fracture process. VIC 2D 7 software was used to determine the peel and shear strain distributions in the overlapped area of bonded joints. Tensile test and DIC results reveal that cork particles enhance the strength and ductility of adhesive joints. However, the effect of cork particles on ductility is more significant than strength of joint. The visual inspection of the captured images shows cork particles act as crack stopper and slow down the crack propagation along the bondline. 30cm.

Design of control system and fabrication of special compartment in Static Refrigerators /

By Arshad, Muhammad Bilal . . 54p. , Refrigerators being used for domestic purposes are of three types, namely static, brewed, and no-frost. The aim of this project was to introduce a new compartment in static refrigerators to enhance the quality and freshness of food present in this compartment. It was achieved by having control over temperature depending on the needs of the user and needs for the type of food inside the compartment. There can be two methods to fabricate this special compartment. One is by using parallel evaporators and other is by using fan and airduct. The parallel evaporator method is expensive but highly efficient, while air duct is less expensive and does not compromise enough efficiency, in term of energy consumption and cooling. The airduct was implanted in the refrigerator and results were taken. The result shows the total time to reach the target temperature, and time to drop per half degree of temperature. The target was to set the temperature at any value between 5 to -5 oC. In this project, the minimum temperature achieved was -1 oC, as the average temperature of evaporator goes to -12 oC, rather than the - 18 oC for most of the domestic refrigerators. 30cm.

Effect of Hygrothermal Aging on Strength Performance of Cork Powder Reinforced Adhesive /

By Sohail, Zulekha . . 100p. , Adhesives play a crucial role across various industries and applications due to their ability to bond materials together. They are used in numerous ways, ranging from everyday household applications to industrial and specialized fields. Strength is the most critical factor to analyze before using the adhesive. Various techniques have already been developed and many are being developed to predict and improve the strength of adhesive. The addition of cork powder to the structural adhesives could improve the strength of adhesive joints through mechanical interlocking between the cork cells and the molecules of adhesive. However, even with the nanofiller reinforcement, the strength of adhesive joints is significantly affected by environmental parameters like temperature and humidity. The present study investigated the effect of hydrothermal aging on the strength characteristics of cork powder-reinforced adhesive samples. Reinforced adhesive samples were investigated under two different humidity levels of 80% and 100% RH. The cork powder will be added in concentration of 0.25wt.%, 0.5wt.%, 0.75wt.% and 1wt.% to study the reinforcing effects. The result shows that the saturated mass increased with increased in relative humidity that is approximately 0.4% and 0.9% for 80% and 100% RH respectively. The findings show that the ultimate tensile strength is reduced by the addition of cork powder as well as enhancing humidity. Furthermore, the addition of cork powder makes the sample more brittle, so failure strain and tensile toughness undergo decrement. The above finding indicated that hot-wet environment has a negative influence on strength performance of cork powder reinforced adhesive. In future the same study can be performed to know the strength of SLJ and DLJ to know its effect on joints. 30cm.

Data Acquisition & Experimental Analysis Of Power Harvesting From Suspension System /

By Hassan, Ahmad Sabur . . 66p. , Energy crisis and environmental problems such as oil shortage and atmospheric pollution have brought challenges for new development of an energy saving, efficient and environment friendly power transmission system in vehicles. This research is focused on how to use the vibrational energy of the suspension system to generate power that would otherwise go as waste. It is demonstrated that the potential energy of driving vibration is sufficient to be utilized as a sustainable energy. The vibrations experienced by the shock absorber of the vehicle when passed through some irregularities on the road are converted into useful energy by using a regenerative linear or rotary mechanism. As shock absorber effect formed, spring is compressed, and linear movement of rack is converted in rotary motion due to pinion moves as the rack is meshed with pinion. And the pinion is mounted on the shaft of the generator which then produce the power. It is then used to calculate the practical power generated from the regenerative shock absorber by taking the real vibrations amplitude data from the road. The vibrations amplitude data is acquired from the road by driving motorcycle on different road conditions with the setup installed in it to calculate and store the vibrations amplitude data. Later, the same data is applied to the testing rig by using pneumatic and Arduino to find out the voltage generated. The power that is practically generated by testing the mechanism on the rig is around 9.5 watts. The harvestable power from the suspension depends on the vehicle speed, road roughness and stiffness of the tire. This regenerated energy is used to charge the battery. 30cm.

Study the effect of shallow cryogenic treatment on mechanical and microstructural properties of 30CrMnSiA steel heat treated in vacuum furnace and Box Type conventional air furnace /

By Aslam, Muhammad Danyal . . 50p. , Heat treatment plays a major role in improving the material properties. With the addition of cryogenic treatment these properties can be further improved. In this paper heat treatment is carried out on low carbon low alloy structural steel in two different types of furnaces conventional box type air furnace and vacuum furnace along with shallow cryogenic treatment with the purpose to investigate the outcome of shallow cryogenic treatment on the material properties and to find out which type of furnace is more suitable with shallow cryogenic treatment. For this purpose, structural steel 30CrMnSiA was selected, and heat treatment was carried out in conventional box type air furnace (900°C × 40mins) and vacuum furnaces (900°C × 70mins), shallow cryogenic treatment (-75°C × 125mins) was carried out after the quenching and before tempering. For the physical properties of the material, hardness (HRC) was investigated using Brinell hardness tester HBD-62-5AP. Tensile samples were prepared as per ASTM E8/E8M and investigated using 100kN WAW-100B Electro-Hydraulic Servo Computer Control Universal Testing Machine. Impact toughness was measured by using electronic pendulum impact testing machine CBD-300 and specimens were prepared using ASTM standard E23-12c. Microstructural analysis for grain structure was carried out using Olympus DSX1000 optical microscope. 30cm.

Assessment of Stress Biomarkers in the Saliva of Smokers and Nonsmokers via UV Photospectrometry and POMS /

By Fahim, Maria . . 99p. , Smoking is one of the major health catastrophes. Smoking is believed to be the major cause of chronic diseases like Cardiovascular complications, stroke, pregnancy issues, respiratory failure, etc. There are three important transdiagnostic emotional factors that make the population vulnerable to initiation of smoking i.e. anhedonia anxiety sensitivity, distress tolerance. Research studies for the past five decades have proven the adverse effect of stress on brain physiology and functioning. The human body responds to trauma (physical or non-physical stress) in a definite manner. This response of the body can be qualitatively and quantitatively monitored through several chemicals in the bloodstream, saliva, or urine; responding to the stress, called stress biomarkers i.e. Brain-derived neurotrophic factor, cortisol, cytokines etc. Saliva delivers an efficient specimen for various diagnostic procedures due to the presence of different biological products and secondary metabolites of xenobiotics and helps in determining the disease progressions as well as therapy outcomes depending on the variations in the markers/triggers. The nature of mindset and mood states are evaluated by a scales designed to rate the behavior of an individual towards the environmental stimuli that may be physical or psychological in nature. This psychological rating scale is known as the profile of mood state (POMS). This scale was initially originated by McNair, Droppleman, and Lorr in 1971. This scale is presented in the form a questionnaire including different questions regarding the mode and feelings of a subject.This research work aims to further elucidate the utilization of UV Photospectrometry for quantitatively assessing POMS and its relation to the stress biomarker. The samples were collected form the vicinity of the university campus H-12 Islamabad. The samples were processed and stored at the biomedical laboratory of School of Mechanical and Manufacturing Engineering (SMME), NUST. A total of twenty-four (24) male subjects were analyzed. A total of two groups were considered. Group 1 included the non-smoking participants, while group 2 included smoking participants. Simple spitting technique was used for the collection of unstimulated saliva. About 4 ml unstimulated saliva was collected in the sterile falcon tube. Saliva was temporarily stored in cool boxes at 4°C and immediately II shifted to the facility. Centrifugation of the salivary sample was done at 4°C for 5 minutes and 10,000 rpm. Saliva sample was frozen at -80°C until sample collection span was completed. The mood state of the participants was also evaluated using the profile of mood state technique used initially by McNair, Lorr, and Droppleman in 1971. The total mood disturbance (TMD) score was calculated that ranges from -32 to 200. The questionnaire was accessed from ―Mackenzie, B. (2001) Profile of Mood States (POMS) [WWW] Available from: https://www.brianmac.co.uk/poms.htm [Accessed 26/6/2022]‖. Simulated neural networking (SNN) was applied to the collected data from smokers and non-smokers for accuracy scoring. The required statistical analysis was performed and the data was statistically analyzed through a software ―GraphPad Prism 8.0‖ and the respective graphs were plotted. UV spectrophotometry studies provided peak plasma concentration peaks at the lower UV range of 190 to 210 nm, but with no significant difference, representing the presence of biological stress markers. The profile of mood state evaluation studies concluded that the smoking participants were presented with a significantly higher level of individual mood profile scores i.e. anger (****, P<0.0001), confusion (**, P<0.0014), fatigue (*, P<0.0354), tension (*, P<0.0422) and stress as compared to nonsmoking participants. The vigorous score was significantly high in the nonsmoking individuals (****, P<0.0001). Similarly, total mood disturbance score was also significantly high in the smoking participants. The application of artificial neural networking through artificial machine learning scored the accuracy of the results 84% which is a reliable outcome. The current research work concludes that different stress stimuli including physiological stress and psychological stress tends to initiate/increase the smoking behavior among the community. Likewise, it is also concluded that smoking initiation may not be always triggered in response to stress. Numerous factors i.e. lack of education, negative inspiration, or behavior to impress are also involved. Furthermore, the adaptation of smoking behavior as a result of stressful stimuli is not a valid approach to reduce the noxious/stressful stimuli. The stress may further be exaggerated by smoking. 30cm.

Experimental Study of Lings Airways /

By Sardar, Hassan . . 55p. , Breathing is phenomenon essential for every mammal on Earth. Key role of respiratory system is transmission of vital gases between air and blood. Conventionally some macroscale techniques for flow visualization in trachea-bronchial region was achieved by using 3D printing of idealized/realistic airways model. Due to limitations in fabrication and CT image resolution, limited amount of experimental study is done on bronchial region. We fabricated simplified model of terminal bronchi airways by using polydimethylsiloxane. Micro-fluidic channel is fabrication by using the 3D printed molds via SLA printer (FormLabs 3+ with layer thickness of 50 μm). The mold is then used to fabricate transparent channel of PDMS which is good for visualization of flow. It is first of its kind of fabrication of terminal bronchial airways by using microfluidic chip fabrication method. Moreover, the chips fabricated using the PDMS have some paybacks like we can easily visualize flow passing through the airways. We use syringe pumps for flow of three breathing conditions sleep, normal and exercise. We demonstrated airways focusing using microscope and visualized fluid flow by using particle image velocimetry method. The statistics evidence good agreement with our experimental results and simulation results from the literature. The results shows that turbulence kinetics energy decreases by using pressurized meter dose inhaler. 30cm.
