Recession is known to cause an increase in stock return predictability. The COVID-19 pandemics had not only resulted in sickness and loss of life but also plunged global economy into recession prompting governments to come up with measures to combat the disease. This paper first confirms that return predictability increased due the spread of COVID-19 using data from 41 countries on variations of popular predictors. Furthermore, it shows that government responses to COVID-19 alleviated the pandemic, the recession and reduced the return predictability with varying impact for different government measures. However, cases and deaths from COVID-19 which should have intensified …

Why Is The Third Principal Component Of The Yield Curve Important: A Point Of View From Reverse Stress Test On Credit Portfolio, Phanuwat Ritpornnarong
Chulalongkorn University Theses and Dissertations (Chula ETD)
The focus of this study is to analyze the shape of the yield curve on credit portfolios during crises, specifically those that are exposed to both interest rate and credit risks. To achieve this, We utilized a reverse stress test (RST) and macroeconomic measures (such as GDP and U.S risk-free yields) from the period of 1981 to 2014 to estimate mathematical models. We then utilized a Monte Carlo simulation to determine the most likely scenario for the measures if the portfolio value reaches a pre-specified threshold. The researchers discovered that the shape of the stressed yield curves varied depending on …
Development Of High Protein Beverage From Hydrolyzed Egg White, Nuntorn Charoensak
Development Of High Protein Beverage From Hydrolyzed Egg White, Nuntorn Charoensak
Chulalongkorn University Theses and Dissertations (Chula ETD)
The primary objective of this study was to examine the impact of enzymatic treatment on pasteurized egg white protein (EWP) and assess its influence on various physicochemical properties and antioxidant activity. Our findings revealed that the addition of SDAY10 enzymes led to a significant increase in lightness (L*), redness (a*), and yellowness (b*) parameters. Furthermore, higher concentrations of the enzyme resulted in a considerable reduction in pH, viscosity, and volume mean diameter (D4,3) of EWP protein compared to the control group (P < 0.05). Additionally, the application of SDAY10 enzyme (0.1-0.3% w/v) for EWP hydrolysis exhibited a noteworthy enhancement in antioxidant activity (measured by DPPH, ABTS, and FRAP assays) compared to lower enzyme concentrations. Notably, the 0.3% concentration of SDAY10 exhibited the highest release of amino acids during in vitro digestion and received the highest sensory evaluation score. Consequently, employing SDAY10 enzymes at a concentration of 0.3% w/v for EWP hydrolysis demonstrates significant potential for improving the physical properties of EWP and enhancing antioxidant activity. However, it is imperative to investigate the sensory evaluation with regards to the bitterness of the product developed using such enzymes.

Effects Of Heat And Uv-C Curing On Properties Of Soy Protein Film, Tanjina Akter
Chulalongkorn University Theses and Dissertations (Chula ETD)
This study aimed to investigate the effects of heat curing and UV-C curing on properties of soy protein film. Both the heat and UV-C treatments were applied to either film-forming solution or pre-formed film. In the first part, film-forming solution or pre-formed film was cured at 60, 70, or 80°C for 2, 4, or 6 h. Heat curing had no effect on film thickness (p>0.05), but it did improve tensile strength of the films. Pre-formed film cured at 70°C for 4 h exhibited the highest tensile strength (3.49 MPa), which was 1.8 times higher than the control. Increasing Raman …

Chulalongkorn University Theses and Dissertations (Chula ETD)
Phachan Samphanbok Geopark showcases fascinating erosional features, such as a multitude of potholes in the Mekong River. Additionally, it is home to the largest pedestal rock in Thailand, located in Ubon Ratchathani province in the northeastern part of the country, near the border between Thailand and Laos PDR. The formation of potholes is attributed to the erosive force of swirling sediment within fractures caused by vortex currents. In this research study on pothole evolution, the potholes in the Mekong River were categorized into two main groups: structural control potholes and non-structural control potholes. These types were further divided into five …
Optimization Of Blast Design For Better Fragmentation & Reduction Of Ground Vibration At Khao Mai Nuan Pyrophyllite Mine, Saraburi Province, Thailand, Arif Khan

Effect Of Salinity Contrast Between Formation Water And Injected Low Salinity Water On Low Salinty Water Flooding In Dolostone Formation, Nuttapol Junput
Chulalongkorn University Theses and Dissertations (Chula ETD)
Low Salinity Waterflooding (LSWF) has gained substantial prominence in current scientific method for oil recovery improvement, owing to its simplicity, cost-effectiveness, and environmental friendliness as an Enhanced Oil Recovery (EOR) technique. Various studies have highlighted the crucial role of injected brine salinity and the concentration of Potential Determining Ions (PDI) in stimulate oil recovery mechanisms. However, the majority of these studies have predominantly concentrated on sandstone reservoirs. In light of the fact that over 50% of hydrocarbon reserves are situated in carbonate reservoirs, this research focuses specifically on dolomite reservoirs to examine the applicability and feasibility of implementing LSWF in …

Simulation Study On Co2 Enhanced Oil Recovery For Offshore Area In Thailand, Pariwat Wongsriraksa
Chulalongkorn University Theses and Dissertations (Chula ETD)
Fossil fuels are widely used all over the world. It generates carbon dioxide (CO2) which is one of the main causes for climate change and global warming. One practical technology to reduce CO2 emission is carbon capture, utilization, and storage (CCUS) which includes the use of CO2 for enhanced oil recovery (CO2EOR) and storage in the geological reservoir. In Thailand, there are some potential geological reservoirs for CO2EOR due to crude properties, depth of the reservoir and oil saturation, especially in the Gulf of Thailand. However, the high temperatures gradient in the Gulf of Thailand can lead to higher minimum …
