To achieve the aim, the first objective is preliminary experiments on preparation of polypropylene blends with silicone elastomer masterbatch and characterize by analysis of mass composition, mechanical properties, and dynamic mechanical properties to investigate any improvement of properties. The silicone elastomer masterbatch will then be substituted with propylene-maleic anhydride graft copolymer waxes or other compatibilizers.

This study focuses on the stability of nano-emulsions produced by phase inversion temperature method using n-Decane and n-Dodecane as the dispersed phase and pure water/brine as the aqueous phase (continuous phase). A non-ionic surfactant (Brij 30) was used in the preparation of the nano-emulsions. Three different types salt namely \(NaCl\), \(KCl\) and \(MgC{l_2}\) were used at different concentrations.

Finance is considered as the lifeblood of the economy and it is integral to a country's economic growth and stability. However, this perception has been called into question, particularly following the global financial crisis, giving rise to new research questions. For example, does too much finance harm economic growth? And does the financial sector serve society's economic and social needs? This thesis aims to provide cross-sectional and time-series evidence on the macroeconomic consequences of financialisation in an international context.

The study "Studies on film forming corrosion inhibitors on aluminium alloy, AA2024-T3" presents key aspects of the film forming behaviour of the selected inhibitors and the test methods used to evaluate the inhibitor induced films in a chloride solution. This study also aims to provide significant insights to the film tenacity, the influence of the molecular structure as well as the film stability in the absence of inhibitors to provide a deeper understanding of the film forming and film breakdown mechanisms.

The failure of inflation targeting regimes in several emerging economies has received renewed interest among academics and policymakers alike. This ineffectiveness can be attributed to worsening fiscal positions in the aftermath of the Global Financial Crisis, which sheds light on the importance of coordinating fiscal policy and monetary policy to achieve price stability. This thesis, therefore, aims to investigate the effects of fiscal policy on the different transmission channels of monetary policy, which ultimately results in high inflation.

The aim of this study is to develop a perspective on culture which would integrate the views of both opposing camps. By applying the principles of ancient Chinese philosophy, especially the Yin-Yang principle, a balanced, holistic conceptualization was proposed which hold that culture is composed of both a stable and a changing dimension, which dialectically transform into each other to give culture a certain degree of stability and inheritability on the one hand, and a momentum for change and variability on the other, in an ongoing, spiraling process of cultural emergence.

This study examined the effectiveness of different antioxidative compounds, namely 0.2% BHA (Butylated hydroxyanisole) + BHT (butylated hydroxytoluene), 0.03% α – tocopherol, and 3% and 6% tea seed oil (TSO) on the oxidative stability of vegetable oils. Four commonly used oils, viz. rapeseed oil (RSO), peanut oil (PNO), sunflower oil (SFO), and soybean oil (SBO), were assessed by the Schall Oven test method and monitored during the 12-day preservation period under 60°C.
