Penelitian ini dilakukan di lapangan GB untuk mendeteksi keberadaan mineral emas dengan metode Induced Polarization IP . Berdasarkan geologi, terdapat adanya sistem epitermal sulfidasi tinggi di wilayah ini. Hal ini ditandai dengan munculnya keberadaan mineral-mineral logam seperti Au, Cu, dan konsentrasi yang cenderung asam di permukaannya. Mineral emas sendiri merupakan...

Latar belakang dan tujuan: Endometriosis susukan dalam (ESD) posterior yang ekstensif memerlukan tatalaksana pembedahan radikal dan lintas disiplin. Modalitas diagnostik standar seperti USG dan laparaskopi lemah dalam menilai ekstensi ESD posterior di lokasi yang sulit terjangkau. MRI berpotensi menjadi modalitas diagnostik pilihan karena bersifat multiplanar dan baik dalam diferensiasi jaringan...

[ABSTRAK
Pada laporan akhir tesis ini telah dikembangkan suatu sistem untuk magnetisasi
bahan magnet menjadi magnet permanen dan demagnetisasi dengan
mengurangi kuat medan magnet suatu magnet permanen. Sistem ini digunakan
untuk magnetisasi bahan magnet seperti Ferit, PrFeB, NdFeB dan jenis
bahan magnet yang lain. Bahan magnet dapat dimagnetisasi menjadi magnet
permanen dengan menerapkan medan magnet sampai...

In the present work, two of the most typical frustrated spin systems—triangular lattice antiferromagnets and edge-shared chain magnets—have systematically been investigated. Despite the crystallographic simplicity of target systems, rich magnetoelectric responses are ubiquitously observed. The current results published here offer a useful guideline in the search for new materials with...
