Response of the lattice across the filling-controlled Mott metal-insulator transition of a rare earth titanate

The lattice response of a prototype Mott insulator, SmTiO3, to hole doping is investigated with atomic-scale spatial resolution. SmTiO3 films are doped with Sr on the Sm site with concentrations that span the insulating and metallic sides of the filling-controlled Mott metal-insulator transition (MIT). The GdFeO3-type distortions are investigated using an atomic resolution scanning transmission electron microscopy technique that can resolve small lattice distortions with picometer precision. We show that these distortions are gradually and uniformly reduced as the Sr concentration is increased without any phase separation. Significant distortions persist into the metallic state. The results present a new picture of the physics of this prototype filling-controlled MIT, which is discussed.Comment: Accepted, Phys. Rev. Let

Karakteristik Habitat Peneluran Chelonia Mydas di Konservasi Teluk Nibung, Singkil sebagai Referensi Mata Kuliah Ekologi Hewan

Habitat penyu untuk bertelur memiliki karakteristik tersendiri seperti tingkat lebar pantai, kelembaban, dan lainya. Kawasan Teluk Nibung menjadi salah satu tempat persinggahan untuk betelurnya penyu hijau. Keberadaan penyu di kawasan Teluk Nibung mulai mengalami penurunan, hal ini disebabkan beberapa faktor seperti kerusakan dan perubahan struktur pantai dan pemburuan yang terjadi pada habitat hidup dan berkembangbiaknya pasca tsunami Aceh 2004. Tujuan penelitian ini adalah untuk mengetahui karakteristik habitat peneluran penyu meliputi lebar pantai, suhu pasir, kelembaban pasir dan kelayakan buku teks yang dihasilkan untuk tambahan referensi Mata Kuliah Ekologi Hewan. Lokasi penelitian ini berada di Kawasan Konservasi Teluk Nibung, Aceh Singkil, Indonesia. Metode penelitian yang digunakan metode purposive sampling. Hasil penelitian menyatakan bahwa suhu pasir pada pagi dan siang memiliki rata-rata tertinggi di banding malam, sedangkan kelembaban pasir kebalikkan dari suhu pasir. Hasil dari uji kelayakan buku teks dari validator media dan materi memiliki skor total 96,54% dengan katagori sangat layak direkomendasikan sebagai salah satu referensi Mata Kuliah Ekologi Hewan

Karakteristik Ordo Collembola di Kawasan Laboratorium Pendidikan Biologi Fakultas Tarbiyah dan Keguruan UIN Ar-Raniry sebagai Referensi Mata Kuliah Zoologi Invertebrata

Collembola merupakan arthopoda primitif, collembola dikenal dengan istilah ekor-pegas karena di bagian ekor terdapat struktur tambahan yakni furcula yang berfungsi sebagai alat pelompat. Namun mahasiwa pendidikan biologi sering kali belum mengetahui tentang Collembola karena tidak ada pembelajaran yang spesifik mengenai kelompok ini serta kurangnya referensi dalam identifikasi. Untuk membantu proses pembelajaran menjadi lebih efektif dapat menggunakan buku identifikasi. Tujuan penelitian ini adalah untuk mengetahui karakteristik Collembola yang ditemukan di Kawasan Laboratorium Pendidikan Biologi dan kalayakan buku identifikasi sebagai referensi tambahan mata kuliah Zoologi Invertebrata. Metode yang digunakan dalam penelitian ini adalah metode perangkap jebakan (Pitfall Trap) dan menggunakan purposive sampling yang dikombinasi dengan metode kuadran. Teknik analisis data meliputi analisis karakteristik spesies Collembola dan uji kelakayan buku identifikasi. Spesies yang ditemukan meliputi: Pseudosinella sp. sebanyak 5 individu, Entomobrya sp. sebanyak 35 individu, Ascocyrtus sp. sebanyak 1 individu, Sinella sp. sebanyak 8 individu, Subisotoma sp. sebanyak 17 individu, Isotomurus palustris sebanyak 1 individu, Proisotoma sp. sebanyak 18 individu, Smintthurinus sp. sebanyak 6 orang, dan Hypogastrura consanguinae sebanyak 10 orang.

Effect of vowel auditory training on the speech-in-noise perception among older adults with normal hearing

Introduction: Aging reduces the ability to understand speech in noise. Hearing rehabilitation is one of the ways to help older people communicate effectively. This study aimed to investigate the effect of vowel auditory training on the improvement of speech-in-noise (SIN) perception among elderly listeners. Materials and Methods: This study was conducted on 36 elderly listeners (17 males and 15 females) with the mean±SD of 67.6±6.33. They had the normal peripheral auditory ability but had difficulties in SIN perception. The samples were randomly divided into two groups of intervention and control. The intervention group underwent vowel auditory training; however, the control group received no training. Results: After vowel auditory training, the intervention group showed significant changes in the results of the SIN test at two signal-to-noise ratios of 0 and -10 and the Iranian version of the Speech, Spatial, and Qualities of Hearing Scale, compared to the control group (P<0.001). Regarding the Speech Auditory Brainstem Response test, the F0 magnitude was higher in the intervention group (8.42±2.26), compared to the control group (6.68±1.87) (P<0.011). Conclusion: This study investigated the effect of vowel auditory training on the improvement of SIN perception which could be probably due to better F0 encoding and receiving. This ability enhancement resulted in the easier perception of speech and its more proper separation from background noise which in turn enhanced the ability of the old people to follow the speech of a specific person and track the discussion. © 2020 Mashhad University of Medical Sciences.
