Dielectronic Recombination Rates In Astrophysical Plasmas

In this work we introduce a new expression of the plasma Dielecronic Recombination (DR) rate as a function of the temperature, derived assuming a small deformation of the Maxwell-Boltzmann distribution and containing corrective factors, in addition to the usual exponential behaviour, caused by non-linear effects in slightly non ideal plasmas. We then compare the calculated DR rates with the experimental DR fits in the low temperature region.Comment: 6 pages, 1 figure, proceedings to the "International Symposium on Nuclear Astrophysics - Nuclei in the Cosmos - IX", 25-30 June 2006, CERN - Genev

Bahasa, sastra, dan teknologi informasi: menyikapi ancaman, menjajaki peluang

Bahasa, sastra, dan teknologi informasi tampak sebagai entitas yang setara atau barangkali kita bisa menyebut bahwa ketiganya memiliki sifat yang sejajar. Tampak tidak ada hal yang istimewa dari ketiganya. Biasa saja. Salah satu di antara ketiganya tiada yang serta merta terlihat superior –berperan sebagai faktor determinan bagi (keberadaan) faktor-faktor yang lain. Melalui pengamatan yang bebas nilai, bahasa, sastra, dan teknologi informasi akan lebih sering dipahami sebagai sebuah realita yang memang sudah seharusnya “begitu” (given), seperti lazimnya bernafas dan berjalan

The Elicit Function of Speech Acts in Questioning on Investigative Interviews in Criminal Inspection of Dump Truck Theft Cases at Cirebon City Police Station

In this study, the data source was obtained from the transcription of dump truck theft cases recorded in the Police Record.  Investigators conducted investigative interviews to obtain information from witnesses and suspects, which led to the suspect's confession.  The investigator asked several questions to the examinee regarding the criminal act.  The data analysis method was carried out by eliminating the answers being examined and focusing on the questions given by the investigator to be classified based on the seven elicit functions of the speech act of asking questions described by Tsui (2002).  It was found that the elicit function in the investigator's question was the function of seeking information (appearing 119 times), repeat function (appear 50 times), clarifying function (appear 47 times), confirm function (appear 43 times), and approve function (appear 11 times).  The elicit function that occurred the most from the questions submitted by investigators was the function of seeking information, which was 119 times out of 270 questions.  In contrast, the function of asking for commitment was not found.

PENERAPAN WAWANCARA INVESTIGATIF DIKAITKAN DENGAN DAYA BUKTI BERITA ACARA PEMERIKSAAN DALAM SISTEM PERADILAN PIDANA DI INDONESIA

Penelitian ini berupaya mengungkap wawancara investigatif dan daya bukti BAP di dalam pemeriksaan perkara pidana. Penelitian ini menerapkan paradigma kualitatif yang berpedoman pada prosedur dan analisis teks grounded theory yang pertama kali dikembangkan oleh Strauss & Corbin (1990) dan Glaser (1992). Paradigma penelitian kualitatif digunakan karena penelitian ini diarahkan untuk memaknai fenomena terkait penggunaan wawancara investigatif dalam pemeriksaan perkara pidana dikaitkan dengan daya bukti BAP sebagai hasil pemeriksaan yang merupakan alat bukti di persidangan. Data dalam penelitian ini mencakup korpus yang berupa tuturan (talks) dan tulisan (texts) yang merupakan produk atau hasil pemeriksaan perkara pidana yang dilakukan penyidik kepada terperiksa. Data verbal berupa wawancara penyidik-terperiksa (saksi/tersangka) dalam penyidikan perkara pidana seperti yang diatur di dalam Pasal 170 KUHP. Sementara itu, tulisan (text) yang digunakan dalam penelitian ini adalah berita acara pemeriksan yang disusun penyidik ketika memeriksa para terperiksa di dalam penyidikan. Kedua jenis data tersebut memiliki kedudukan yang sama (setara) di dalam penelitian ini. Analisis linguistik dilakukan secara praktis di ranah hukum dengan alasan bahwa penegakan hukum pada hakikatnya merupakan aktivitas berbahasa dan turut dipengaruhi oleh faktor-faktor di luar bahasa. Penelitian dilakukan dengan multimetode dengan kerangka analisis didasarkan pada teori yang dikembangkan dalam pragmatik. Hasil penelitian menunjukkan bahwa jenis pertanyaan penyidik lebih banyak yang bersifat produktif, dibandingkan tak produktif. Sementara itu, fungsi pertanyaan berhasil mengungkap unsur pokok pidana yang disangkakan kepada para tersangka. Selanjutnya, jenis tindak tutur penyidik seluruhnya termasuk ke dalam tuturan direktif. Hal ini menunjukkan dominasi penyidik di dalam pemeriksaan, sementara jenis tuturan terperiksa didominasi tuturan asertif. Terakhir, diskrepansi informasi terjadi dalam bentuk penambahan informasi, penghilangan informasi, dan kesalahan tafsir informasi. Namun, diskrepansi informasi itu tidak mengganggu pemaknaan atas BAP yang disusun penyidik. Sebab, diskrepensi informasi yang terjadi pada umumnya teridentifikasi pada peripheral crime details, bukan main crime details. Berdasarkan keempat temuan di atas, dapat disimpulkan bahwa berita acara pemeriksaan yang disusun penyidik dengan teknik wawancara investigatif mampu menyokong daya bukti yang tinggi bagi berita acara pemeriksaan (BAP) yang disusunnya. This research seeks to reveal investigative interviews and evidence of the police investigation report (BAP) in the investigation of criminal cases. This study applies a qualitative paradigm based on procedures and grounded theory text analysis first developed by Strauss & Corbin (1990) and Glaser (1992). The paradigm of qualitative research is used because this research is directed to interpret the phenomenon related to the use of investigative interview in criminal case investigation related with police investigation report as the result of examination which is evidence in the trial. The data in this study include the corpus in the form of speech (talks) and writing (texts) which is the product or result of criminal investigation conducted by the investigator to the examination. Verbal data in the form of interview investigator-examined (witness/suspect) in criminal case investigation as regulated in Article 170 of the Criminal Code. Meanwhile, the writing (text) used in this study is the news of the examination of the investigator prepared when examining the examiners in the investigation. Both types of data have the same position (equivalent) in this study. Linguistic analysis is done practically in the realm of law on the grounds that law enforcement is primarily a language activity and is influenced by factors outside the language. The research was conducted in multimetode with an analytical framework based on the theory developed in pragmatics. The results showed that the types of investigator questions were more productive, than unproductive. Meanwhile, the function of the question succeeded in uncovering the principal element of the criminal suspected to the suspects. Furthermore, the type of investigative speech act entirely belongs to the directive directive. This indicates the investigator's dominance in the examination, while the type of spoken utterance is dominated by assertive speech. Finally, discrepancies of information occur in the form of information addition, information omission, and misinterpretation of information. However, the discrepancy of the information does not interfere with the interpretation of the police investigation report compiled by the investigator because discrepancy information that occurs in general is identified on peripheral crime details, not main crime details. Based on the above four findings, it can be concluded that the police investigation report prepared by the investigator with the investigative interview technique is able to support the excellent evidence for the police investigation report (BAP) he compiled

MEMS Devices for Miniaturized Gas Chromatography

In the era of the Internet of Things, the need for mobile devices able to analyze accurately real samples with sometimes very small volumes is a must. Gas chromatography (GC) is a common laboratory technique widely used for analyzing semi-volatile and volatile compounds. However, this technique is not suitable to be used outside labs. The development of micro-machined processes encouraged the development of miniaturized gas chromatographs. This chapter focuses on the recent development in the field of miniaturized gas chromatography and its component up to the present in various fields of analyses
