Adapting authoritarianism: institutions and co-optation in Egypt and Syria
No full textThis PhD thesis compares Egypt and Syria’s authoritarian political systems. While the tendency in social science political research treats Egypt and Syria as similarly authoritarian, this research emphasizes differences between the two systems with special reference to institutions and co-optation. Rather than reducibly understanding Egypt and Syria as sharing similar histories, institutional arrangements, or ascribing to the oft-repeated convention that “Syria is Egypt but 10 years behind,” this thesis focuses on how events and individual histories shaped each states current institutional strengthens and weaknesses. Specifically, it explains the how varying institutional politicization or de-politicization affects each state’s capabilities for co-opting elite and non-elite individuals.
Beginning with a theoretical framework that considers the limited utility of democratization and transition theoretical approaches, the work underscores the persistence and durability of authoritarianism. Chapter two details the politicized institutional divergence between Egypt and Syria that began in the 1970s. Chapter three and four examines how institutional politicization or de-politicization affects elite and non-elite individual co-optation in Egypt and Syria. Chapter five discusses the study’s general conclusions and theoretical implications.
This thesis’s argument is that Egypt and Syria co-opt elites and non-elites differently because of the varying degrees of institutional politicization in each governance system. Rather than view one country as more politically developed than the other, this work argues that Syria’s political institutions are more politicized than their Egyptian counterparts. Syria’s political arena is, thus, described as politicized-patrimonialism. Syria’s politicized-patrimonial arena produces uneven co-optation of elites and non-elites as they are diffused through competing institutions. Conversely, the Egyptian political arena remains highly personalized as weak institutions and individuals are manipulated and molded according to the president’s ruling clique. This is referred to as personalized-patrimonialism. As a consequence, Egypt’s political establishment demonstrates more flexibility in ad hoc altering and adapting its arena depending on the emergence of crises.
This study’s theoretical implications suggest that, contrary to modernization and democratization theory’s adage that institutions lead to a political development, politicized institutions within a patrimonial order actually hinder regime adaptation because consensus is harder to achieve and maintain. It is within this context that Egypt’s de-politicized institutional framework advantages its top political elite. In this reading of Egyptian and Syrian politics, Egypt’s personalized political arena is more adaptable than Syria’s. These conclusions do not indicate that political reform is a process underway in either state

Intellectual property laws and Islam in Malaysia.
No full textPhDThis study is undertaken on the premise that Islam and Islamic law is to be taken into
serious consideration in any future legislative reform of laws in Malaysia. Islam being
the religion of the country and the strong religious sentiment of the Muslims (who
form the majority in Malaysia) cannot be overlooked or dismissed lightly by the
legislators in Malaysia. Reformation of intellectual property laws is timely, as we are
now approaching to the dateline set by GATF-Trips agreement which aim is to
improve our standard of intellectual property protection. This study seeks to analyze
and evaluate the current legislation pertaining to intellectual property in Malaysia in
terms of the philosophy and rules governing the existence, ownership and exercise of
these rights and their consistency and inconsistency with Islam and Islamic law. The
main objective of this study is to prove that a coherent and logical conceptual
framework of ownership of intellectual property can be derived from an Islamic
perspective which not only offers the basis of rights but also defines the scope of
these rights. From the point of ownership of rights, support can be obtained from the
normative framework of property rights within the traditional classification of 'mal'
(property) and 'haqq al-milkiyyah' (ownership rights) under Islamic law. From the
point of exercise of rights, the exact scope can be defined from the analysis of
fundamental concepts which have been developed by Muslim jurists. It has been
established that Islam and Islamic law offers a sound and systematic paradigm, which
in deeper analysis, can satisfy both our current obligations under international
treatises, as well as our responsibility to practise our religion to the fullest

Novel CO2 Separation Membranes
No full textUsing membranes for CO2 capture has gained recent prominence in the global scientific community due to its lower capital cost and a quicker separation performance than the conventional separation methods. The membrane process features desirable properties, like compactness, energy efficiency, and environmental friendliness. Various polymeric and inorganic materials have been tested both as unique ingredients and blends to form CO2 separation membranes with a focus on increasing the performance but have had varying rates of success. For commercial viability, the membrane sector requires new techniques and testing materials to lower the cost of CO2 capture. Recently, thermally rearranged polymers, intrinsic microporous polymers, ionic liquid inclusion as fillers, and binary fillers have all emerged as novel trends, focusing on enhancing the working efficiency and sustainability of the membranes. This chapter explores the most recent advances in membrane technology and its future prospects as a sustainable solu ion towards carbon dioxide capture.

Jet Sintering of High Temperature Carbon Steel Powder Particles
No full textCutting process by using abrasive saw produces millions of tiny sparkling particles
ripped apart from the original material. These particles are sent to fly in the air for a few
milliseconds before hitting a substrate. If remain untouched, this particles will be
collected as an aggregate on the surface of the substrate. It will gradually form a small
hill with some interesting characteristics to be studied further. So, in this project, the
author had studied the microstructure of the collected particles and learned about the
new mechanism of sintering inside the material. In order to achieve the objective, the
author cut the material into few parts. Then, the author mounted, grinded, polished and
etched each part of it. Then, the author studied the samples under optical microscope.
The author will also used Micro Vickers harness testing to check its mechanical
properties. From all these steps, the author managed to observe some of the steel
microstructure from it. The author also calculated the porosity of the material under
microscopy using scale approximation. The author was able to learn about new kind of
mechanism inside the material which will help us to understand more about sintering
process. As a conclusion, this project was based on research of new kind of mechanism
involved in this material. It is just a matter of time for us to unlock the secrets of this
technique, its mechanisms and the outcome from this proces
