The collapse of single bubbles and approximation of the far-field acoustic emissions for cavitation induced by shock wave lithotripsy
Full text linkRecent clinical trials have shown the efficacy of a passive acoustic device used during shock wave lithotripsy (SWL) treatment. The device uses the far-field acoustic emissions resulting from the interaction of the therapeutic shock waves with the tissue and kidney stone to diagnose the effectiveness of each shock in contributing to stone fragmentation. This paper details simulations that supported the development of that device by extending computational fluid dynamics (CFD) simulations of the flow and near-field pressures associated with shock-induced bubble collapse to allow estimation of those far-field acoustic emissions. This is a required stage in the development of the device, because current computational resources are not sufficient to simulate the far-field emissions to ranges of O(10 cm) using CFD. Similarly, they are insufficient to cover the duration of the entire cavitation event, and here simulate only the first part of the interaction of the bubble with the lithotripter shock wave in order to demonstrate the methods by which the far-field acoustic emissions resulting from the interaction can be estimated. A free-Lagrange method (FLM) is used to simulate the collapse of initially stable air bubbles in water as a result of their interaction with a planar lithotripter shock. To estimate the far-field acoustic emissions from the interaction, this paper developed two numerical codes using the Kirchhoff and Ffowcs William–Hawkings (FW-H) formulations. When coupled to the FLM code, they can be used to estimate the far-field acoustic emissions of cavitation events. The limitation of the technique is that it assumes that no significant nonlinear acoustic propagation occurs outside the control surface. Methods are outlined for ameliorating this problem if, as here, computational resources cannot compute the flow field to sufficient distance, although for the clinical situation discussed, this limitation is tempered by the effect of tissue absorption, which here is incorporated through the standard derating procedure. This approach allowed identification of the sources of, and explanation of trends seen in, the characteristics of the far-field emissions observed in clinic, to an extent that was sufficient for the development of this clinical device

Ide dan Perjuangan Jamaluddin Al-Afghaniy dalam Mewujudkan PAN Islamisme
Full text linkSkripsi ini studin tentang tokoh intelektual Jamaluddin al-Afghaniy dalam mewujudkan Pan Islamisme. Pokok Permasalahan adalah bagaimana ide dan perjuangan Jamaluddin al-Afghaniy dalam mewujudkan Pan Islamisme. Masalah ini dilihat dengan pendekatan historis dan politik.
Jamaluddin al-Afghaniy adalah tokoh Islam yang terkemuka pada abad ke-19. Dia berusaha melahirkan ide-ide pembaharuan dan salah satu ide pembaharuannya adalah Pan-Islamisme, sebuah gagasan untuk membangkitkan dan menyatukan kaum muslimin akibat dominasi Barat yang telah menciptakan desintegrasi politik dunia Islam.
Inti Pan-Islamisme terletak pada ide bahwa Islam adalah satu-satunya ikatan kekuatan kaum Muslimin. Jika ikatan diperkokoh akan menjadi sumber kehidupan dan pusat loyalitas mereka, maka kekuatan solidaritas negara Islam yang luar biasa akan memungkinkan pembentukan dan pemeliharaan negara Islam yang kuat dan stabil.
Ide Pan-Islamisme, Jamaluddin al-Afghaniy menjadikan Islam sebagai Ideologi anti-kolonialis yang menyerukan aksi politik menentang Barat. Menurut Dia, Islam adalah faktor yang paling esensial untuk perjuangan kaum Muslimin melawan Eropa, dan Barat pada umumnya
Prediction of far-field acoustic emissions from cavitation clouds during shock wave lithotripsy for development of a clinical device
No full textThis study presents the key simulation and decision stage of a multi-disciplinary project to develop a hospital device for monitoring the effectiveness of kidney stone fragmentation by shock wave lithotripsy (SWL). The device analyses, in real time, the pressure fields detected by sensors placed on the patient's torso, fields generated by the interaction of the incident shock wave, cavitation, kidney stone and soft tissue. Earlier free-Lagrange simulations of those interactions were restricted (by limited computational resources) to computational domains within a few centimetres of the stone. Later studies estimated the far-field pressures generated when those interactions involved only single bubbles. This study extends the free-Lagrange method to quantify the bubble–bubble interaction as a function of their separation. This, in turn, allowed identification of the validity of using a model of non-interacting bubbles to obtain estimations of the far-field pressures from 1000 bubbles distributed within the focus of the SWL field. Up to this point in the multi-disciplinary project, the design of the clinical device had been led by the simulations. This study records the decision point when the project's direction had to be led by far more costly clinical trials instead of the relatively inexpensive simulations. <br/

PEMIKIRAN POLITIK JAMALUDDIN AL-AFGHANI DALAM BUKU PEMIKIRAN POLITIK ISLAM PERSPEKTIF SIYASAH
Full text linkABSTRAK
Jamaluddin Al-Afghani (1839-1897) M, adalah seorang pemimpin
pembaharuan dalam Islam yang juga perintis pertama modernis Islam
khususnya aktivisme Islam anti imperialis. Jamaluddin Al-Afghani
merupakan tokoh yang menganjurkan untuk kembali pada tradisi muslim
dengan cara yang sesuai dengan berbagai problem dalam memperkuat dunia
muslim untuk menghadapi bangsa Barat. Jamaluddin Al-Afghani melihat
bahwa keadaan itu merupakan malapetaka bagi umat Islam, bahwa dunia
Islam sedang menjadi permainan politik bangsa penjajah dari Barat,
khususnya Inggris dan merupakan ancaman yang serius bagi Dunia
Islam.Permasalahan yang dibahas dalam penelitian ini yaitu, bagaimana
pemikiran politik Jamaluddin Al-Afghani dalam buku Pemikiran Politik
Islam dan bagaimana Persepektif Siyasah. Tujuan dari penelitian ini yaitu,
untuk mengetahui Pemikiran politik Jamaluddin Al-Afghani yang ada dalam
buku Pemikiran Politik Islam dan bagaimana pemikiran Poitik Jamaluddin
Al-Afghani dalam Perspektif Siyasahnya. Jenis Penelitian ini menggunakan
penelitian pustaka (library research), yaitu suatu penelitian yang dilakukan
dengan cara mengumpulkan mengumpulkan buku-buku yang berubungan
dengan Skripsi ini, dan sifat penelitian ini termasuk penelitian yang
menggunakan metode deskriptif-analitis, artinya dengan mendeskripsikan
Pemikiran politik Jamaluddin Al-Afghani untuk kemudian dianalisis secara
logis. Sehingga mendapat suatu kesimpulan terhadap pemikiran politik
Jamaluddin Al-Afghani. Berdasarkan hasil penelitian dapat disimpulkan
bahwa pemikiran politik Jamaluddin Al-Afghani dalam buku Pemikiran
politik Islam yakni Jamaluddin memegang peran penting dalam gerakan
politik Islam modern. Ia dikenal luas di Dunia Islam Sunni dan Syi’ah serta
sangat berpengaruh terhadap Dunia Islam, terutama karena perhatiaanya yang

Jamaluddin al-Afghani dan Karir Politiknya
Full text linkAbstract
In its history, Islam has had a phase where it has progressed in various ways, one of which is in the political realm. This is marked by the number of areas that were successfully conquered by Islam so that its teachings also developed very rapidly. However, in history, Islam has also experienced a period of decline where there have been many divisions among internal Muslims as well as due to external influences, and some of the causes are the advancement of Western civilization so that it affects the existence of the world of Islamic politics as well. The data obtained from this paper comes from various references in the form of books, journals, and other writings. Then the data is reviewed to produce a conclusion. In this paper, we will discuss how Jamaluddin al-Afghani's efforts in arousing the spirit of unity of the Muslim community in order to escape from western influences and shadows, as well as his efforts to improve the internal conditions of Muslims, both social, political and religious. Jamaluddinal-Afghani the first reformer in Islam who brought salafiyah under the banner of Pan Islamism, with the principle that Muslims wherever he is is the Unity of Brothrhood or a unity of brotherhood that must be fostered continuously. Jamaluddin said that the only most revolutionary way to liberate the fate of Muslims from colonialism, imperialism and materialism was politics imbued with religion. Jamaluddin, as an Islamic reformer, tried hard to improve Islam from within by completely attacking superstition, khurafat and bid'ah.
