Skripsi, Jurusan Teknik Mesin, Fakultas Teknik, Universitas Negeri Malang. Pembimbing: (I) Drs. H. Paryono, S.T., M.T., (II) Drs. H. Sumarli, M.Pd., M.T. Kata Kunci : Turbojet Accelerator, Gas Buang, Karbon monoksida, Hidrokarbon Pencemaran udara yang disebabkan gas buang kendaraan bermotor merupakan ancaman bagi kesehatan makhluk hidup. Hal itu disebabkan karena pertumbuhan jumlah kendaraan bermotor semakin meningkat pada setiap tahunnya. Upaya yang dilakukan pemerintah untuk mengurangi emisi gas buang diantaranya dengan dikeluarkan Peraturan Menteri Negara Lingkungan Hidup Nomor 5 Tahun 2006 tentang ambang batas emisi gas buang kendaraan bermotor. Keadaan ini pasti membutuhkan solusi salah satunya pengurangan emisi gas buang kendaraan bermotor. Salah satu upaya alternatif untuk memaksimalkan pembakaran adalah dengan membuat aliran putar turbulen pada fluida kerja (swirl) sehingga mengoptimalkan pencampuran udara dengan bahan bakar salah satunya dengan turbojet accelerator. Penelitian ini bertujuan (1) untuk mengetahui jumlah emisi gas buang (CO dan HC) yang dihasilkan mesin yang belum terpasang Turbojet Accelerator dan sudah terpasang Turbojet Accelerator. (2) Untuk mengetahui apakah ada pengaruh pada penggunaan Turbojet Accelerator terhadap emisi gas buang CO. (3) Untuk mengetahui apakah ada pengaruh pada penggunaan Turbojet Accelerator terhadap emisi gas buang HC. Penelitian ini menggunakan jenis metode eksperimen dengan menggunakan dua variabel penelitian. Variabel bebas dalam penelitian ini adalah jenis Turbojet Accelerator, variabel terikat dalam penelitian ini adalah emisi gas buang. Penelitian untuk menguji emisi gas buang dilaksanakan di Laboratorium Suzuki Universitas Negeri Malang. Data yang diambil dari rpm 1000 sampai 4000 dengan kenaikan 500 rpm. Teknik analisis data yang digunakan adalah analisis statistik parametrik menggunakan metode statistik Paired Sample t Test dengan bantuan SPSS 20 for Windows. Hasil penelitian yang didapat pada penelitian tersebut ialah, pemasangan Turbojet Accelerator memberikan dampak positif yaitu berkurangknya kadar CO dan HC setelah pemasangan Turbojet Accelerator. Hasil tersebut dipengaruhi oleh pusaran yang terjadi di intake manifol sehingga campuran udara dan bahan bakar lebih homogen yang berakibat pada pembakaran yang sempurna. Berdasarkan hasil diatas dapat disimpulkan bahwa terdapat pengaruh pemasangan Turbojet Accelerator terhadap emisi gas buang CO dan HC pada Suzuki Aerio pada putaran 1000 rpm, 1500 rpm, 2000 rpm, 2500 rpm, 3000 rpm, 3500 rpm, dan 4000 rpm

Roman primacy and the development of the synodal institution in the period of the Arian controversy
No full textThe object of this study is process of evolution of church organization in the 4th century, especially the relationships between Roman primacy and synodal institution in the epoch of the Arian controversy. The author examines evolution of the institution of the Roman synod and practice of participation of the Roman See in church councils outside Rome, focusing on the unsuccessful attempt to convene the general council in Rome in 382. Analysis of historical data shows that the ability of the Roman see to organize in a short time a representative council (mainly of the Italian bishops) allowed Rome to claim for a special status within the church communion. In the same time the Roman See did not become in the 4th century the center of conciliar activity at the universal level. Participation of Rome in Ecumenical and Western councils was quite passive. In the second part of the paper the author attempts to reconstruct various models of church organization, which were typical for the western and the eastern episcopate in the 4th century. The author concludes that the real initiator of the development of universal primacy of Rome was not originally the pope, but the western episcopate (council of Serdica, 343). In the second part of the 4th century pope Damasus developed this conception, putting the principle of primacy of the Roman See as the chair of Peter above principle of synodal consensus. At the same time eastern bishops considered the Roman chair as the center of the West, rather than the head of the whole Church. Sometimes they invited bishop of Rome and other western bishops to act as arbiters in the eastern conflicts, but more often they defended the idea of full autonomy of the East

Sustained epidermal growth factor receptor levels and activation by tethered ligand binding enhances osteogenic differentiation of multi-potent marrow stromal cells
No full textAuthor Manuscript 2011 April 29.Epidermal growth factor receptor (EGFR)-mediated signaling helps regulate bone development and healing through its effects on osteogenic cells. Here, we show how EGFR activity and osteogenic differentiation responses in primary human bone marrow-derived multipotent stromal cells (MSCs) are influenced by presenting covalently tethered epidermal growth factor (tEGF) on the culture substratum, a presentation mode that reduces EGFR internalization and restricts signaling to the cell surface. In both absence and presence of tEGF, MSCs increase expression levels of EGFR and its heterodimerization partner HER2 during the course of osteogenic differentiation. tEGF substrata increased levels of phosphorylated EGFR and phosphorylated extracellular regulated kinase (ERK) compared to control substrata, and these elevations were associated with a twofold enhancement of MSC alkaline phosphatase activity at day 7 and matrix mineralization at day 21. Surprisingly, addition of soluble EGF (sEGF) to cells cultured on tEGF substrata reduces osteogenic differentiation, even though EGFR signaling is more strongly activated in acute, short-term manner by sEGF treatment than by tEGF treatment. A striking concomitant result of the sEGF effects is near-complete downregulation of EGFR and HER2, demonstrating that the tEGF/EGFR interaction is dynamically reversible even though temporally sustained. Taken together, our results show that enhanced MSC osteogenic differentiation corresponds to a sustained combination of receptor expression and ligand presentation, both of which are maintained by tEGF.National Institutes of Health (U.S.) (Grant R01-GM059870-07)National Institutes of Health (U.S.) (Grant R01-DE 019523-10)National Institutes of Health (U.S.) (Grant P40RR017447)United Negro College Fund (Merck Postdoctoral Fellowship)Georgia Institute of Technology (FACES Fellowship)National Center for Research Resources (U.S.) (Grant P40RR017447

Preliminary Field Evaluation of a Custom-Built Titanium Antenna Locator Device
Abstract:
This document presents an initial field-based evaluation of a custom-built antenna‑type locator device designed by the author. The device is claimed to detect metallic targets at distances up to 300 meters and to indicate the approximate position of the target. The purpose of this report is to document the structure of the device, summarize field results, and provide access to video evidence and user feedback.
Introduction:
Antenna‑based locating devices have been discussed for many years, yet their performance remains controversial due to the lack of controlled scientific studies. The author has developed a new locator device with a titanium body and a multi‑chamber internal structure. Although the external design is simple, the device is reported to demonstrate capabilities not observed in commercial detection systems such as OKM or Minelab. The goal of this report is to present the device, describe its claimed performance, and provide publicly accessible documentation for further independent evaluation.
Device Structure:
The locator consists of a titanium body and three internal chambers:
- one chamber inside the handle,
- one chamber at the tip of the antenna,
- and one chamber at the rear section of the antenna.
Each chamber contains a proprietary mixture of materials selected by the author. The exact composition is not disclosed for intellectual‑property reasons. According to the author, this internal configuration contributes to the device’s sensitivity and long‑range response.
Field Performance Claims:
The author reports that the device is capable of:
- detecting metallic targets at distances up to 300 meters,
- identifying the approximate direction of the target,
- and narrowing down the final position with high accuracy.
More than 200 trainees have reportedly used the device in real field conditions, and many of them have successfully located buried metallic objects. Over 180 video demonstrations have been published online.
Evidence and Documentation:
All field tests, demonstrations, and user results are publicly available on the author’s Instagram page. The videos include real‑world tests, trainee feedback, and practical demonstrations of the device’s operation.
