چکیده

Perairan Kepulauan Sula dan Taliabu merupakan perairan yang memisahkan dua laut dalam di bagian utara selatan kepulauan, Laut Maluku Banda, dengan tiga pulau besar utama yaitu Pulau Mangoli, Taliabu, Sanana. tersebut memiliki dinamika kompleks topografi dasar tidak teratur adanya sill pada kolom serta dilintasi oleh Arus Lintas Indonesia (ARLINDO) Pintasan Lifamatola. Kompleknya pengaruh pasang surut kuat menyebabkan diperlukan suatu kajian tersendiri untuk menguraikan berbagai fenomena oseanografi terjadi sehingga diperoleh pemahaman baru mengenai tersebut. Pendekatan numerik melalui pemodelan hidrodinamika dimensi dilakukan mengetahui profil perairan. Fokus aspek arus penyederhanaan barotropik. Penelitian menggunakan data sekunder dari ERA-5, PUSHIDROSAL, MIKE DHI, BRSDM KKP. Hasil penelitian menunjukkan bahwa karakter Campuran Condong Harian Ganda dominansi konstituen Pasut kepulauan adalah K1 M2. Karakteristik sifat bervariasi diantara kecepatan maksimum rerata. model memperlihatkan mencapai 5,555 m/s rata-rata tertinggi 2,373 m/s. Pola saat bergerak menuju sedangkan rerata condong ke arah barat pergerakan selatan. The waters of the and Islands are that separate two-deep seas in northern southern parts archipelago, Sea Banda Sea, with three main large islands, namely Mangoli Island, Sanana Island. These have complex dynamics irregular bottom topography water column crossed by Indonesian Through Flow on Lifamatola Passage. complexity strong tidal influences requires a study to describe various oceanographic phenomena occur so new understandings these obtained. A numerical approach through three-dimensional hydrodynamic modeling is carried out determine profile waters. focus aspects ocean currents tides barotropic simplification. was conducted using secondary obtained from results showed Mixed Tide Prevailling Semi diurnal predominance Tidal constituents part archipelago islands Current characteristics vary between maximum average speeds. show speed reaches highest current pattern at time moves towards north while west movement south.

Regulation of SulA cleavage by Lon protease by the C-terminal amino acid of SulA, histidine.

SulA protein, a cell division inhibitor in Escherichia coli, is degraded by Lon protease. The C-terminal eight residues of SulA have been shown to be recognized by Lon; however, it remains to be elucidated which amino acid in the C-terminus of SulA is critical for the recognition of SulA by Lon. To clarify this point, we constructed mutants of SulA with changes in the C-terminal residues, and e...

Proof. There are three cases: (1) A and B are in the same column. Then, since in each column we picked the shortest student, A is shorter than B. (2) A and B are in the same row. Then, since in each row we picked the tallest student, B is taller than A. (3) A and B are neither in the same row, nor in the same column. Let C be a student who is in the same row as A and in the same column as B. Th...

An objection to the memetic approach to culture Memetics is one possible evolutionary approach to the study of culture. Boyd and Richerson's models (1985, Boyd this volume), or my epidemiology of representations (1985, 1996), are among other possible evolutionary approaches inspired in various ways by Darwin. The memetic approach is based on the claim that culture is made of memes. If one takes...

Many scientists have until recently considered consciousness to be unsuitable for scientific research. As Damasio remarks, ‘studying consciousness was simply not the thing to do before you made tenure, and even after you did it was looked upon with suspicion’ (Damasio, 1999, p. 7). Prompted by technological developments as well as conceptual changes, this attitude has changed within the last de...
