MEMPERTIMBANGKAN NILAI ADIL DALAM WARISAN (Perspektif Nasr Hamid Abu Zayd)
No full textNasr Hamid Abu Zayd who has some thoughts related to the Qur'an is a contemporary Islamic critical thinker . He said that al Qur’an is a cultural product, this statement made him get under public criticism. However, besides that there are interesting things in the thought of Nasr Hamid Abu Zayd when discussing gender issues including in terms of division of inheritance which according to the author has not been known to the public. The idea that carried Nasr Hamid Abu Zayd is what the author needs to describe conceptually. Research on Gender Deconstruction Perspective Nasr Hamid Abu Zayd was done in order to answer: 1) How is the Qur'an according to Nasr Hamid Abu Zayd? 2) How is the legacy in the Qur'an according to Nasr Hamid Abu Zayd? This paper would like to reconstruct the thoughts of Nasr Hamid Abu Zayd on the Qur'an and the concept of justice in the inheritance. In order to reconstruct the thought of Nasr Hamid Abu Zayd, the author used theoretical hermeneutical of Schleirmacher’s. theory
Flow Reactor Oxidation of Ammonia–Hydrogen Fuel Mixtures
No full textHydrogen-assisted oxidation of ammonia under flow reactor conditions was investigated through experiments and chemical kinetic modeling. Novel experiments, conducted in a tubular laminar flow reactor as a function of the NH3/H-2 ratio, stoichiometry, and temperature (725-1475 K), were analyzed along with literature results from tubular and jet-stirred flow reactors. Ignition and oxidation of NH3 is strongly promoted by the presence of H-2 under all conditions investigated. In general, the behavior is captured well by the kinetic model. With an increasing fraction of H-2 in the fuel mixture, the generation of chain carriers gradually shifts from being controlled by the amine reaction subset to being dominated by the oxidation chemistry of H-2, which is known more accurately. However, under reducing conditions, the H-2 consumption rate is strongly underpredicted. This shortcoming suggests that the thermochemistry of amine radicals and/or the formation of higher amines need further assessment. The present analysis shows that for lean oxidation of NH3/H-2 mixtures in tubular flow reactors, data obtained at higher temperatures, particularly for NO formation, may be strongly affected by the reaction during preheating or by mixing (dependent on reactor design) in the inlet section prior to the isothermal zone. Modeling predictions for the high pressure, medium-temperature ignition conditions in a large diesel engine indicate that NH3/H-2 fuel mixtures may still require a cofuel to secure stable ignition
Reliability updating of experienced Hydraulic Structures by account of inspections: Case study: Poiree weir Roermond
No full textThe Dutch Ministry of Infrastructure and Environment manages approximately five hundred hydraulic structures and is responsible for the remaining life of these experienced structures. In this report, we developed a reliability analysis for the case study poiree weir Roermond. The inspections carried out by IV-Infra on the poiree weir Roermond concludes a rise to high risk e.g. a high probability of occurrence and major consequential loss primarily related to the observed erosion damage at the embedded poiree trestles located upstream river. The remaining life of hydraulic structures is in general the expected lifespan, on the condition that the structure does not fail in the expected lifespan also known as ‘reference period’. The remaining life can be determined as one can predict the deterioration and be able to predict in what condition the poiree weir will be. When the service life time is assumed a random variable, the strength condition can be modeled as a stochastic process, and thus the remaining life too. There is doubt concerning the structural safety because of this deterioration, a reliability assessment of experienced hydraulic structures must be therefore reviewed for use during the remaining life instead of the general reference period and are therefore not to be considered equal.The lognormal distribution with skewness k<1 is an appropriate method to model the strength deterioration behavior. The future condition can’t be exactly determined because of the introduction of the deterioration model uncertainty. Nevertheless, the effect of the inspection data on the reliability level can be illustrated by the likelihood of the strength at the moment of inspection and can be estimated better with a Bayesian afterwards probability. The increase of the actual number of inspections further reduces the uncertainty of the strength deterioration.The Dutch Ministry of Infrastructure introduced the "experienced reliability level". The experienced reliability level is the minimum level of structural safety for experienced structures in main waterways. For the reference period and remaining life of 30 years, the following reliability index β = 3.3 is the lower limit for the structural safety for existing structures. The survival probabilities can then be given as reliability index, and compared with the minimum reliability level of experienced structures. To maintain the reliability level at the target level, the remaining life of the poiree weir is the period within which the minimum reliability level of experienced structures should not be less. The remaining life for without inspections and n=9 inspections is calibrated to 7 years, the increase of the number observations n=100 increases the remaining service life to 11 years. One can say that inspection increases the remaining life. This is great of importance for the planning of maintenance.Dutch Ministry of Infrastructure and EnvironmentExperienced reliability level of hydraulic structuresPoiree weir RoermondMaster project reportMaster internshi

Analysis of Hamid Mawlana's Thoughts on Islamic Communication Theory
No full textThis paper explores Islamic communication theory developed by Hamid Mowlana (1979, 1993, 2007). The analysis includes the context of the emergence of a discourse on Islamic communication in the academic realm and the elaboration and criticism of the substance of Hamid Mowlana’s Islamic communication theory. Using the literature study method, the author found that the emergence of Islamic communication theory was motivated by the meeting of two streams of criticism of Western science, namely the criticism of Islamic intellectuals against the paradigm of Western social science (and therefore, against western modernization); and the tendency towards international communication studies by emphasizing the DE westernization approach, motivated by the cultural turn in the development of the social sciences. Hamid Mowlana formulated Islamic communication theory by proposing the concept of tabligh initially developed from his studies of communication practices and systems in Iran, especially around the period before and after the revolution. Tabligh, besides being a theory, is also an ethic and is based on five fundamental principles: Tauhid, Amar ma’ruf nahi munkar, Ummah, Taqwa, and Amanah. Hamid Mowlana’s Islamic communication theory has its weaknesses, especially in its basic assumptions about Islamic exceptionalism and the singularity of Islamic and Western civilizations
Receptor tyrosine phosphatase PTPγ is a regulator of spinal cord neurogenesis
No full textDuring spinal cord development the proliferation, migration and survival of neural progenitors and precursors is tightly controlled, generating the fine spatial organisation of the cord. In order to understand better the control of these processes, we have examined the function of an orphan receptor protein tyrosine phosphatase (RPTP) PTPγ, in the developing chick spinal cord. Widespread expression of PTPγ occurs post-embryonic day 3 in the early cord and is consistent with a potential role in either neurogenesis or neuronal maturation. Using gain-of-function and loss-of-function approaches in ovo, we show that PTPγ perturbation significantly reduces progenitor proliferation rates and neuronal precursor numbers, resulting in hypoplasia of the neuroepithelium. PTPγ gain-of-function causes widespread suppression of Wnt/β-catenin-driven TCF signalling. One potential target of PTPγ may therefore be β-catenin itself, since PTPγ can dephosphorylate it in vitro, but alternative targets are also likely. PTPγ loss-of-function is not sufficient to alter TCF signalling. Instead, loss-of-function leads to increased apoptosis and defective cell-cell adhesion in progenitors and precursors. Furthermore, motor neuron precursor migration is specifically defective. PTPγ therefore regulates neurogenesis during a window of spinal cord development, with molecular targets most likely related to Wnt/β-catenin signalling, cell survival and cell adhesion.</p

KRITIK HAMID FAHMY ZARKASYI TENTANG HERMENEUTIKA DALAM ISLAMISASI ILMU (PERSPEKTIF ARKEOLOGI PENGETAHUAN MICHEL FOUCAULT)
No full textPandangan para pemikir tentang teori Hermeneutika sampai saat ini masih problematis, kritik dan komentar paling keras terhadap Hermeneutika ini muncul dari ranah agama-agama yang harus diakui merupakan ladang paling subur bagi lahirnya “klaim kebenaran”. Di Indonesia, Hamid Fahmy Zarkasyi yang dikenal sebagai tokoh Islamisasi Ilmu adalah yang paling kritis dalam menentang Hermeneutika. Mengenai kritik Hamid, dapat kita lihat dalam karyanya seperti buku, jurnal, seminar dan sikap keberatannya terhadap teori ini. Oleh karna itu, penelitian ini bertujuan untuk mengetahui bagaimana arkeologi pengetahuan Hamid?, mulai dari bagaimana pengetahuannya terbentuk, dikembangkan dan didistribusikan. Selain itu, mengapa ia mengkritik penggunaan Hermeneutika dalam Islamisasi Ilmunya?, penelitian ini berupaya menelusuri wacana, relasi dan makna di balik fakta.
Jenis penelitian ini masuk dalam kategori kajian pustaka (literature research), penyajian data riset ini dilakukan secara kualitatif menggunakan pendekatan Arkeologi Pengetahuan dari Michel Foucault. Prosesnya terdiri dari: pengumpulan sumber (heuristik), analisis-kritis, verifikasi dan penulisan. Studi ini merupakan cara untuk mengumpulkan data dari pelbagai karya Hamid Fahmy Zarkasyi dan dilengkapi dengan wawancara. Berdasarkan kajian dan analisis, tesis ini memiliki dua kesimpulan. Pertama, Arkeologi Pengetahuan Hamid Fahmy Zarkasyi dimulai saat ia menemukan kesamaan Framework berfikirnya ketika berguru dengan Syed Muhammad Naquib al-Attas dan Alparslan Acikgenc di Internasional Institute of Islamic Thought and Civilization (ISTAC). Secara Genealogis, al-Attaslah yang nantinya menjadi rantai-wacana pengetahuan Hamid. Kemudian, mereka menjadikan konsep
Worldview Islam sebagai cara pandang Islam tentang realitas dan kebenaran. Dari wacana Worldview Islam ini, dilanjutkan dengan Islamisasi Ilmu, yang disemaikan Hamid di Gontor sejak 2006 hingga saat ini. Dari wacana Islamisasi Ilmu, Hamid kemudian berpendapat bahwa Hermeneutika tidak sesuai dengan Worldview Islam. Dengan seperangkat alat ‘kekuasaan’ yang dimiliki, Hamid mendistribusikan pengetahuan-nya melalui pengajaran (seperti di kampus dan seminar) dan pelembagaan (seperti UNIDA dan INSISTS) yang Hamid pimpin. Kedua, argumentasi kritik Hamid tentang Hermeneutika diantaranya yaitu, kekhawatiran karna Hermeneutika berasal dari Barat-Kristen yang dapat membahayakan aqidah Islam, Hermeneutika memposisikan al-Qur’an sebagaimana teks-teks lain yang tidak sakral, Hermeneutika memposisikan Allah sebagai ‘the author’, Hermeneutika tidak mengikuti model prosedural dari Tafsir yang ada, Hermeneutika menyamakan setatus Hermes dengan Muhammad sebagai ‘penerima pesan’, para pendukung Hermeneutik adalah mereka yang sudah dihegomoni Worldview Barat (pluralitas pemahaman). Hermeneutika dianggapnya sebagai ‘westernisasi ilmu’ dan ‘tantangan dalam peradaban Islam’. Maka solusi dari masalah ini, menurut Hamid adalah dengan menjadikan Worldview Islam sebagai cara pandang, dan gagasan Islamisasi Ilmu sebagai konsep metodologisnya
Organisational Change in Political Parties in Iran after the Islamic Revolution of 1979. With Special Reference to the Islamic Republic Party (IRP) and the Islamic Iran Participation Front Party (Mosharekat)
No full textAbstract:
The aim of this study is to develop a historical analytical narrative of the development of political parties under the Islamic Republic of Iran, accounting for their organisational structures, ideological evolution and internal distributions of power; to provide an analysis of the change in Iranian political parties after 1979; to examine their intra-party dynamisms of power as well as the developments in the environment of the Iranian parties which stimulated their change. This study gives special reference to the Islamic Republic Party (IRP) and the Islamic Iran Participation Front Party (Mosharekat).
Also to address the problem of poor party institutionalisation in Iran after the revolution by examining a combination of factors that have contributed to the disruption of the institutionalisation process in the Iranian political parties such as at the hostility and uncertainty in party environment, the organisational zones of uncertainty in the Iranian political parties and the impact of state on party institutionalisation in Iran.
Finally to examine the typological similarities between at least one modern party in Iran (Mosharekat) and some parties in the Western Democracies to understand whether partial similarity in society dimensions such as advancements in technology and the emergence of a new social cleavage map instead of the old social stratification, have resulted in similarities in the party types in Iran and the West
