The Azores-Canary-Madeira region has been a focal point of scientific investigation regarding the presence and characteristics of mantle plumes, but so far seismological studies of the region's mantle structure have been limited due to sparse seismic coverage.  Global tomography models exhibit considerable discrepancies concerning the presence and morphology of a lateral connection between  the Azores and Canary plume systems in the mantle. Furthermore, few seismic studies have examined potential interactions between the region's lithosphere, plumes and the adjacent Mid-Atlantic Ridge. Related highly relevant topics include characterising the age-dependent variability in oceanic lithosphere thickness and illuminating lithospheric and sub-lithospheric seismic structure. To address these issues, it is crucial to not only image isotropic seismic wave speeds but also map seismic anisotropy, as it can provide unique constraints on lithospheric thickness, fabric, and ultimately mantle flow. We build a new radially anisotropic tomographic model of the Azores-Canary-Madeira region using the partitioned waveform inversion method. Ocean bottom seismometer data from the UPFLOW array are combined with seismic data from nearby land stations. Automated waveform fitting of surface waves between ~ 300 and ~16 s period is used to retrieve path average model perturbations. These perturbations are subsequently used to invert for 3-D radially anisotropic mantle structure with a regularized least squares inversion. Mantle flow is interpreted from the retrieved patterns in isotropic velocity and radial anisotropy, while depth-dependent trends in these parameters provide insights into the region's oceanic lithosphere thickness and on potential plume-ridge and plume-lithosphere interactions.

The authority of digital public discourse indirectly impacts one's religious point of view, the phenomenon of digital religion has caused mainstream Islamic websites to strive for the dominance of the public digital mass. This paper will examine the phenomenon of competition among mainstream Islamic websites and mainstream non-affiliated websites in seizing public digital dominance. Data Reportal on Digital Indonesia 2023 put Indonesia as the largest internet users in the world, with a population of around 277,7 million with a total active internet user of 212,9 million, internet penetration stood at 77,0 percent. Indonesia also home to 167,0 million social media users equating to 60,4 percent of the total population. Total of 352,8 million cellular mobile connections were active in Indonesia, this figure equivalent to 128,0 percent of the total population. The paper elaborates the prevalent competition between Islamic media using a phenomenological approach based on digital data and a variety of digital analysis tools. This study demonstrates how the intensity of contestation persists and has subsequently created digital communities with divergent religious viewpoints that have subconsciously created social segmentation that strengthens group exclusivism.

The fasalatan book is a form of Kiai Asnawi's concern for Muslims, especially for early childhood, in the context of forming a Muslim personality who always obeys and worships Allah, especially in terms of prayer. This study aims to reveal the contents of the book Fasalatan in the perspective of worship education for early childhood. This research is a library research with data collection methods through interviews and documentation and an interpretive descriptive approach. The primary data source is the book of Fasalatan, the secondary is related works. According to Kiai Asnawi, religious education in the form of prayer is important for children. He reminded the Muslims and their children to always pray five times a day because without doing the five prayers the Muslims and their children would suffer losses.

The optimum value choice of a tightening effort is significant for assurance of a reliable operation of a group bolted joint. A work goal consists in the calculation and comparison of essential conditions of tightening efforts for a bolted joint of a bracket and a plate with analytical and numerical methods. For the first time it is obtained that the use of tightening factors recommended in literature by the condition of joint density may fail to ensure its non-disclosure. It is shown that a basic load factor for a bolt of a group joint depends not only upon bolt and flanges yielding, but upon loading and geometrical parameters of a joint. Basic loading factors obtained through a finite element method for a group bolted joint proved to be below ones defined analytically. The use of the procedure for bolt calculations on the basis of the assurance of joint complete non-disclosure results in increased values of tightening efforts caused by non-uniformity of contact stress distribution in flanges because of tightening. There is specified a field of application of the calculation procedure on joint non-disclosure – group joints with high stiffness flanges. At preliminary estimate the efforts for tightening a standard group joint a procedure of joint non-disclosure with the increased tightening factor and a condition of shift absence is recommended for use. To obtain a reliable estimate of the required tightening effort after its preliminary selection it is recommended to check up operation conditions of a group bolted joint with the aid of the calculation through the finite element method.

In this paper, we study the boundary value problem for loaded differential equations of fractional order with the Barrett operator in the main part.

Judul Buku : Madrasah Para Kiai: Refleksi Untuk Satu Abad Perguruan Islam athali’ul Falah Penulis : M. Imam Azis, dkk. Penerbit : Keluarga Mathali’ul Falah Yogyakarta Tahun terbit : I, 2012 Halaman : xvi + 187 halaman Setiap lembaga pendidikan tentu memiliki orientasi keilmuan yang telah dipilih guna mengantarkan peserta didiknya menuju pintu kesuksesan masing-masing. Ada lembaga yang hanya berorientasi dunia kerja (ekonomi). Ada pula lembaga yang hanya melulu hanya mengejar akhirat, dengan sedikit mempertimbangkan dunia. Kedua model lembaga ini cenderung mendikotomikan agama dan dunia. Selain itu, ada suatu lembaga pendidikan yang mencoba memadukan kedua tujuan pembelajaran sebelumnya. Namun, di era serba instan dan pragmatis ini model lembaga yang ketiga ini sudah mulai ditinggal oleh masyarakat. Padahal sebagai umat muslim seharusnya mampu mengintegrasikan antara dunia dan akhirat sebagai tujuan pendidikan. Salah satu lembaga pendidikan Islam yang istiqa>mah memadukan keilmuan yang bersifat agama dan duniawi adalah Mathali’ul Falah (selanjutnya disingkat Mathali’). Lewat buku berjudul “Madrasah Para Kiai; Refleksi Untuk Satu Abad Perguruan Islam Mathali’ul Falah” para alumninya ingin mengenalkan dan membuktikan sisi idealitas keilmuan itu. Sehingga meskipun berada di tengah-tengah perubahan arus lembaga pendidikan yang berorientasi pada dunia kerja, Mathali’ mampu konsistensi dan bersaing. Bahkan dalam kurikulum pendidikan -yang setara dengan MI/SD sampai MA/SMK/SMA-Mathali’ tidak mengikuti Sistem Pendidikan Nasional yang dianggap sementara ahli-pendidikan ‘gagal’ membentuk peserta didik yang berkarakter dan berwawasan moral-agamis.
