Impact of Asian continental outflow on the concentrations of O3, CO, NMHCs and halocarbons on Jeju Island, South Korea during March 2005

As part of ABC-EAREX2005 experiment, numerous trace gases were measured at Gosan on Jeju Island, South Korea in March 2005 to characterize the impact of recent outflow from the Asian continent and to inter-compare measurement techniques used by participating groups. Here we present measurements of O3, CO, and whole air samples of methane, C2-C8 non-methane hydrocarbons (NMHCs) and C1-C2 halocarbons obtained during the study. The large temporal variations in the measured trace gas concentrations at Gosan were due to the transport of background marine air and of regional pollution mainly from the Chinese subcontinent. Average mixing ratios (± s.d.) were 54.6 (± 9.0) ppbv and 283 (± 100) ppbv for O3 and CO, respectively. CO showed good correlations (r2 = 0.62-0.81) with combustion tracers such as ethyne and benzene but poorly correlated (r2 = 0.11-0.29) with light alkanes, suggesting that the latter were contributed by non-combustion source(s). Back trajectory analysis showed that air masses mainly originated from the North China Plains and northeastern China, which together accounted for 64% of the total trajectories. The highest mean mixing ratios of O3 and combustion-derived species were found in air masses from eastern China and Korea, indicating the significant impact of emissions from these regions. Interestingly, air masses from northeast China contained elevated levels of light alkanes and the smallest ratios of ethyne/propane and benzene/propane among the air-mass groups, suggesting contribution from natural gas leakage in the upwind region, possibly from Siberia. © 2007 Elsevier Ltd.

Faculty Rewards and Education Portfolios: A Report on Faculty Perceptions

Many schools in the developed world have adopted portfolios in an attempt to address the scholarship of teaching. This is because of the atmosphere of “publish or perish” which pervades academia. Buying off teaching obligations with research dollars is an increasingly pervasive practice in many institutions and Faculty caught up in this system have generally gone along with it, focusing on the scholarship of discovery at the expense of the scholarship of integration, application, and teaching - little of which carries the financial consequence or peer recognition of sponsored research.1 Add to this the fact that many medical schools world wide have adopted teacher- intensive, integrated hybrid PBL curricula and the result is frustrated teachers who undergo occupational burnout. An ideal faculty reward system should support the priorities and mission of the institution e.g. if improving the quality of teaching and learning is a high priority, then the tenure, promotion, and merit pay system must support quality efforts to redesign the curriculum, improve courses, and increase the effectiveness of teaching.2 Education Portfolios are not widely used in this part of the world, and few Faculty have even heard of the term “Education Scholarship”. This study is a preliminary report on perception of the faculty rewards in place in their institution and their familiarity with the concept of education scholarship. A questionnaire was posted to Faculty of medical schools in Malaysia and also distributed to staff of the National University of Singapore, during an international conference. A total of 54 responses were collected from six institutions (14 were unidentified); representing a response rate of about twenty per cent. Thirty two were teaching in a hybrid curriculum; and 26 were clinical teachers. Thirty three had been in their respective institutions for more than three years.Faculty Rewards; Education Portfolios; medical schools

Controlled low-temperature molecular manipulation of sexiphenyl molecules on Ag(111) using scanning tunneling microscopy

A novel scanning tunneling microscope manipulation scheme for a controlled molecular transport of weakly adsorbed molecules is demonstrated. Single sexiphenyl molecules adsorbed on a Ag(111) surface at 6 K are shot towards single silver-atoms by excitation with the tip. To achieve atomically straight shooting paths, an electron resonator consisting of linear standing wave fronts is constructed. The sexiphenyl manipulation signals reveal a pi-ring flipping as the molecule moves from hcp to fcc site. Abinitio calculations show an incorporation of the Ag atom below the center of a pi-ring.Comment: 4 pages, 4 figures, accepted for publication in Phys. Rev. Let

Hybrid Iwasawa algebras and the equivariant Iwasawa main conjecture

This is the author accepted manuscript. It is currently pending publication by Johns Hopkins University Press - to appear in the American Journal of Mathematics.Let p be an odd prime. We give an unconditional proof of the equivariant Iwasawa main conjecture for totally real fields for an infinite class of one-dimensional non-abelian p-adic Lie extensions. Crucially, this result does not depend on the vanishing of the relevant Iwasawa µ-invariant.It is a pleasure to thank Werner Bley, Ted Chinburg, Takako Fukaya, Lennart Gehrmann, Cornelius Greither, Annette Huber-Klawitter, Mahesh Kakde, Kazuya Kato, Daniel Macias Castillo, Cristian Popescu, J¨urgen Ritter, Sujatha, Otmar Venjakob, Christopher Voll, Al Weiss and Malte Witte for helpful discussions and correspondence. The authors also thank the referee for several helpful comments.

Law, Liberty and the Rule of Law (in a Constitutional Democracy)

In the hunt for a better--and more substantial--awareness of the “law,” The author intends to analyze the different notions related to the “rule of law” and to criticize the conceptions that equate it either to the sum of “law” and “rule” or to the formal assertion that “law rules,” regardless of its relationship to certain principles, including both “negative” and “positive” liberties. Instead, he pretends to scrutinize the principles of the “rule of law,” in general, and in a “constitutional democracy,” in particular, to conclude that the tendency to reduce the “democratic principle” to the “majority rule” (or “majority principle”), i.e. to whatever pleases the majority, as part of the “positive liberty,” is contrary both to the “negative liberty” and to the “rule of law” itself

Advanced Car Security System Using GSM

Abstract- This system proposes the design and construction of an advanced car security system using GSM. It uses the GSM mobile communication networks to transmit alarm signal and control instruction. The control and communication between the user and the proposed system are achieved through a short message services (SMS) protocol available in the mobile phone. If the car door is illegally opened or the car is vibrated, an alarm will be activated and it send SMS message to the owner’s mobile phone immediately and automatically. The user could easily protect and control their car anywhere at any time. The proposed system consists both hardware and software parts. The hardware components include vibration sensors, a PIC microcontroller, a GSM modem, LCD and buzzer. The software part includes a program controller interface. PIC MikroC programming language is used for this control system. The control system is based on the PIC16F877A microcontroller and AT COMMAND
