Conversion of methanol to light olefins on SAPO-34: kinetic modeling and reactor design
No full textIn this work, the reaction scheme of the MTO process was written in terms of elementary steps and generated by means of a computer algorithm characterizing the various species by vectors and Boolean relation matrices. The number of rate parameters is very large. To reduce this number the rate parameters related to the steps on the acid sites of the catalyst were modeled in terms of transition state theory and statistical thermodynamics. Use was made of the single event concept to account for the effect of structure of reactant and activated complex on the frequency factor of the rate coefficient of an elementary step. The Evans-Polanyi relation was also utilized to account for the effect of the structure on the change in enthalpy. The structure was determined by means of quantum chemical software.
The number of rate parameters of the complete reaction scheme to be determined from experimental data is thus reduced from 726 to 30. Their values were obtained from the experimental data of Abraha by means of a genetic algorithm involving the Levenberg-Marquardt algorithm and combined with sequential quadratic programming.
The retained model yields an excellent fit of the experimental data. All the parameters satisfy the statistical tests as well as the rules of carbenium ion chemistry. The kinetic model also reproduces the experimental data of Marchi and Froment, also obtained on SAPO-34. Another set of their data was used to introduce the deactivation of the catalyst into the kinetic equations.
This detailed kinetic model was used to investigate the influence of the operating conditions on the product distribution in a multi-bed adiabatic reactor with plug flow. It was further inserted into riser and fluidized bed reactor models to study the conceptual design of an MTO reactor, accounting for the strong exothermicity of the process. Multi-bed adiabatic and fluidized bed technologies show good potential for the industrial process for the conversion of methanol into olefins
Impes modeling of volumetric dry gas reservoirs with mobile water
No full textAs the importance of natural gas as a resource increases, the importance of volumetric dry gas reservoirs with mobile water as the dominant gas reservoir types will also increase.
This research developed an efficient, user-friendly simulation program specifically designed to model two-phase flow of gas and water in these reservoirs. Since fluid compression and viscous forces are the dominant parameters that control fluid movement in a dry gas reservoir, we used the Implicit Pressure and Explicit Saturation (IMPES) formulation of flow equations in which neither gravity nor capillary pressure terms are pertinent. Therefore, the IMPES approach showed greater stability for all cases considered in this work. The developed simulator is a Visual Basic Application (VBA) code for which the users can obsereve the results in a pertinent Microsoft Excel file.
This program allows users to study the depletion behavior of volumetric dry gas reservoirs with mobile water as efficiently and accurately as is now possible in more expensive commercially available reservoir simulators. The program was validated by comparing the results with a well-recognized commercial reservoir simulator (CMG). The results of a battery of tests of this simulator matched very well with results of the commercial reservoir simulator for all tested schemes including different simulation plans; reservoir, grid and fluid data; and well configurations.
The observed applicability of the program suggests when dealing with volumetric dry gas reservoirs with mobile water there is no need to employ more expensive commercial reservoir simulators, as the program can reliably be used for any simulation scheme of this case. Furthermore, the program can later be applied in a more robust reservoir simulator as the part that handles dry gas cases
Impact of Web technologies on student-lecturer expert power relationship
No full textExpert power is “the power that comes from having knowledge and expertise in a particular area” (Nazarko, 2004). In the history of the development of higher education, the relationship between the lecturer and the students has changed because of many different factors. Before the internet and web revolution, the lecturer used to be the main information source for his/her students. The web as a modern source of knowledge is now used universally and this spreading trend might affect the relationship between the lecturer and his students. Understanding the impact of this change appears to be important as it would be employed in improving teaching techniques. In this area, many studies have focused on the impact of using the internet and web applications on students and lecturers. These studies have widely investigated this impact on student’s achievements, attitude and also have shown how the role and performance of the faculty have changed. This paper aims to investigate the impact of using web resources as a source of knowledge on the student-lecturer relationship from students’ perspectives. The investigation focuses on how students’ knowledge gained from using websites has impacted on the relationship with their lecturer as a knowledgeable person which theoretically means Expert power. 1661 students from 30 universities/ educational institutions participated in this research
Combined source-channel coding for a power and bandwidth constrained noisy channel
No full textThis thesis proposes a framework for combined source-channel coding under power and bandwidth constrained noisy channel. The framework is then applied to progressive image coding transmission using constant envelope M-ary Phase Shift Key (MPSK) signaling over an Additive White Gaussian Channel (AWGN) channel. First the framework for uncoded MPSK signaling is developed. Then, its extended to include coded modulation using Trellis Coded Modulation (TCM) for MPSK signaling. Simulation results show that coded MPSK signaling performs 3.1 to 5.2 dB better than uncoded MPSK signaling depending on the constellation size. Finally, an adaptive TCM system is presented for practical implementation of the proposed scheme, which outperforms uncoded MPSK system over all signal to noise ratio (Es/No) ranges for various MPSK modulation formats.
In the second part of this thesis, the performance of the scheme is investigated from the channel capacity point of view. Using powerful channel codes like Turbo and Low Density Parity Check (LDPC) codes, the combined source-channel coding scheme is shown to be within 1 dB of the performance limit with MPSK channel signaling
Democracy in Pakistan: Value Change and Challenges of Institution Building
No full textDemocracy as a system of governance and interest representation demands respect for dissent and opposition. It recognises the principle of majority rule and guarantees protection of minorities. Democracy also builds faith in electoral contestation to gain public office and gives legitimacy to political parties as primary instruments for acquisition and transfer of power from one set of individuals to another. Unfortunately, despite the significance of the above elements, no serious studies have been undertaken on Pakistan’s experimentation with democracy. Given a history of weak party system and prolonged military rule, most of the studies focus on the military, political parties, constitutional history, or in a descriptive way, attribute the failure of democracy to the inadequacies of the politicians [Ahmed (1987); Rizvi (1987); Callard (1957) and Afzal (1976)]. It is only recently that some theoretically meaningful and rigorous empirical writings have appeared on elections, procedures and practices of electoral contestation and on problems of transition from authoritarian regimes towards democracy [Waseem (1989); Wilder (1995); Talyor (1992); Rais (1997) and Shafqat (1997)]. It merits attention and recognition that among the Muslim states and developing world, Pakistan is one of those few states, where people have shown vigour and some vitality to adopt a democratic parliamentary system and through popular mass movements demonstrated disapproval of military dictatorships. An enduring feature of Pakistani culture, history and politics has been an aspiration for democracy [Hugh and Rose (1997)]. The passion for democracy continues to resurge, despite ethnic, social class, religious cleavages, strong authoritarian tendencies and prolonged military rule.
Hermeneutika Al-Qur’an Kontekstual: Metode Menafsirkan Al-Qur’an Abdullah Saeed
No full textQuranic exegesis has a special place in the development of Islamic intellectual tradition and civilization at large. As the main source of Islamic teaching, for centuries Muslims have attempted to understand the various meanings of the Qur’an in order to be in line with the current needs of the society through the process of contextualization. In this article, the author presents and explains the way in which Abdullah Saeed, a professor in Islamic studies from the the University of Melbourne, Australia, contextualize the meaning of the Quran. In particular, this article analyzes some methodological aspects proposed by Saeed in the qontextualization of the Qur’an: 1) identifying the world of the text; 2) analyzing text critically; 3) connecting the text to the early Islamic community as the first receivers; and 4) relating the text to the current needs of society. Keywords: Quranic exegesis, Abdullah Saeed, tafsir methodology, contextualization
Bunga bank konvensional menurut pandangan Abdullah Saeed
No full textBunga adalah salah satu pendapatan yang dihasilkan oleh perbankan konvensinal. Dalam praktiknya, yang menggunakan sistem bunga ini bukan hanya di bank saja, tetapi di lembaga keuangan non bank pun juga ada yang menggunakan sistem bunga sebagai sumber pendapatan bisnisnya. Untuk menjelaskan mengenai bunga bank pada penelitian ini, penulis merujuk pada pemikiran Abdullah Saeed. Saeed berpandangan bahwa bunga bank konvensional tidaklah haram, karena tidak mengandung unsur-unsur yang merupakan tujuan utama pelarangan riba.
Rumusan Masalah: Pertama, Bagaimana bunga bank menurut Abdullah Saeed? Kedua, Bgaimana relevansinya dalam dunia perbankan di Indonesia? Jenis penilitian yang digunakan adalah kepustakaan (library research) yaitu mengumpulkan data atau karya ilmiah yang bertujuan dengan objek penelitian atau pengumpulan data yang bersifat kepustakaan, baik berupa buku, catatan, maupun laporan hasil penelitian dari penelitian terdahulu.
Hasil penelitian ini: pertama, Abdullah Saeed memandang bahwa pinjaman dengan sistem bunga tidak menyebabkan ketidakadilan, maka pinjaman tersebut dibolehkan. Saeed melihat bahwa riba di zaman jahiliyah berbeda dengan mekanisme sistem bunga dalam perbankan konvensional saat ini, apalagi sampai pada terjadinya penindasan dan penganiyaan yang dilakukan oleh kreditur kepada debitur. Kedua, Dilihat dari relevansi sosial ekonomi, budaya ekonomi dan ekonomi serta politik ekonomi mengenai bunga bank jika dihubungkan dengan pemikiran Abdullah Saeed di Indonesia saat ini yaitu sangatlah berkaitan. Karena bunga bank memiliki dampak positif bagi bank konvensional maupun para nasabah yang sudah menanamkan modalnya. Dari sistem bunga ini, tidak hanya salah satu pihak saja yang diuntungkan, tetapi kedua belah pihak. Selain itu, transaksi pinjam meminjam dalam sistem perbankan juga dilakukan secara jelas, terbuka dan dilindungi oleh undang-undang. Jadi, kegiatan perbankan di Indonesia sekarang ini sangatlah berkaitan sekali dengan pemikiran Abdullah Saeed tersebut, dan tidak ada pihak yang dirugikan dari sistem bunga bank ini.
ABSTRACT
Interest is one of the incomes that generated by conventional bank. In practice, those who use this interest system are not only banks, but also non-bank financial that use the interest system as a source of their business income. In this study, the author refers to the thoughts of Abdullah Saeed. Saeed thinks that conventional bank interest is not unlawful, because it does not contain elements which are the main purpose of prohibiting usury.
The problem of this study: first, What is the bank's interest according to Abdullah Saeed? Second, What the relevant among the interest and Indonesian banking? The type of research used is library research which is collecting data or scientific work aimed at the object of research or collection of library-based data, both in the form of books, notes and research reports from previous research.
The results of this study: first, Abdullah Saeed views that loans with an interest system do not cause inequity, it is permitted. Saeed sees that usury in the jahiliyah era was different from the current system of conventional banking's interest, moreover it leads to the persecution and abuse by creditors to the debtor. Second, Seeing from the relevance of socio-economic, cultural-economic and political-economic regarding to bank interest if it linked to Abdullah Saeed's thinking in Indonesia today, it is very relevant. Because bank interest has a positive impact on conventional banks its elf and the customers who have invested their capital. From this system, both parties get the benefits. In addition, lending and borrowing transactions in banking system are also carried out clearly, openly and protected by law. So, Indonesian banking activities are very closely related to Abdullah Saeed's thinking and no party is harmed from this bank's interest system
Neutralization of Tetanus Neurotoxin with Various Botulinum Antitoxins (A-F) in a Study to Isolate Clostridium botulinum from Field Samples
No full textIn a study to isolate Clostridium botulinum from field samples, 53 C. botulinum-like isolates were found neutralizable by botulinum antitoxins using the standard mouse bioassay. The neutralization results of 14 of them were found false-positive due to contamination with C. tetani which was separated from these isolates and found neutralizable by the same botulinum antitoxin types. Due to this result, C. tetani was isolated from other five field samples to test their toxins by botulinum antitoxins. They were also found neutralizable by certain botulinum antitoxins. Supernatants of C. tetani isolates were confirmed by being neutralized by tetanus antitoxin. Tetani toxins were found neutralizable by different botulinum antitoxins (A-F) but mainly by polyvalent type ABE (Aventis Behring, Marburg) and type CD mixture (Onderstepoort Veterinary Institute, Onderstepoort). These results were mainly attributed to the non-specificity of the proteins of some (at least ABE and CD) botulinum antitoxin hyperimmune sera which may contain antibodies against C. tetani as well
