Jackson Jr. First page of article [source] Testing of the SIBERIA landscape evolution model using the Tin Camp Creek, Northern Territory, Australia, field catchmentEARTH SURFACE PROCESSES AND LANDFORMS, Issue 2 2002G. R. Hancock Abstract The SIBERIA landscape evolution model was used to simulate the geomorphic development of the Tin Camp Creek natural catchment over geological time. Measured hydrology, erosion and geomorphic data were used to calibrate the SIBERIA model, which was then used to make independent predictions of the landform geomorphology of the study site. The catchment, located in the Northern Territory, Australia is relatively untouched by Europeans so the hydrological and erosion processes that shaped the area can be assumed to be the same today as they have been in the past, subject to the caveats regarding long-term climate fluctuation. A qualitative, or visual comparison between the natural and simulated catchments indicates that SIBERIA can match hillslope length and hillslope profile of the natural catchments. A comparison of geomorphic and hydrological statistics such as the hypsometric curve, width function, cumulative area distribution and area,slope relationship indicates that SIBERIA can model the geomorphology of the selected Tin Camp Creek catchments.

POWELL Abstract James Arthur Prescott was a prominent soil scientist whose career responded to an increasingly complex, recognisably Australian web of interpenetrating spatial scales, served to promote revolutionary global advances in his chosen field, and in the process negotiated the blurred boundaries between ,pure' and ,applied' research. Encounters with this instructive life suggest that, while resolutions of pivotal anxieties might turn on ineluctably personal qualities, they also reflect a dynamic interplay between international, imperial, national and state contexts. Prescott's innovative contributions to soil science, fruits of a tenaciously consolidated career, influenced resource appraisal and environmental management across a prodigious continental expanse. A sustained focus on local and regional development brought him into contact with a wide range of contemporaries, including pioneering geographers, and culminated in his election to a Fellowship of the Royal Society.

[source] Optimization of AlGaN/GaN HEMTs for high frequency operationPHYSICA STATUS SOLIDI (A) APPLICATIONS AND MATERIALS SCIENCE, Issue 7 2006T. Palacios In the article [1] featured at Editor's Choice, the structure and processing of AlGaN/GaN high electron mobility transistors (HEMTs) have been optimized for maximum small signal gain at high frequencies. The cover picture combines the sample structure , shown schematically and in a scanning electron microscopy image , with the band diagram of the sample with an InGaN back-barrier used to increase the electron confinement in comparison to a standard HEMT. The first author, Tomás Palacios, is currently a Project Scientist at UCSB. His research interest focuses on the search of novel GaN-based transistors for mm-wave applications and biological sensors. He is one of the winners of the physica status solidi Young Researcher Awards for his outstanding presentation at the 6th International Conference on Nitride Semiconductors held in Bremen, Germany, in 2005. Further articles from ICNS-6 will also be published in phys. stat. sol. (b) 243, No. 7 (2006) and phys. stat. sol. (c) 3, No. 6 (2006). The present issue of phys. stat. sol. (a) as well as phys. stat. sol. (c) 3, No. 5 (2006) also contain papers presented at the International Conference on Nanoscale Magnetism (ICNM-2005) in Gebze, Turkey. [source] Martin Stutzmann: Editor, Teacher, Scientist and FriendPHYSICA STATUS SOLIDI (C) - CURRENT TOPICS IN SOLID STATE PHYSICS, Issue 2 2005Manuel Cardona On 2 January 1995 Martin Stutzmann became Editor-in-Chief of physica status solidi, replacing Professor E. Gutsche, who had led the journal through the stormy period involving the fall of the Iron Curtain, the unification of Germany and the change in its Eastern part, where physica status solidi was based, from "socialism as found in the real world" (a German concept) to real world capitalism. In 1995 it was thought that the process had been completed (we should have known better!) and after the retirement of Prof. Gutsche the new owners of physica status solidi (Wiley-VCH) decided that a change in scientific management was desirable to adapt to the new socio-political facts and to insure the scientific continuity of the journal. Martin had moved in 1993 from my department at the Max-Planck-Institute to Munich where he soon displayed a tremendous amount of science man- agement ability during the build-up of the Walter Schottky Institute. The search for a successor as Edi- tor-in-Chief was not easy: the job was not very glamorous after the upheavals which had taken place in the editorial world following the political changes. Somebody in the Editorial Boards must have suggested Martin Stutzmann. I am sure that there was opposition: one usually looks for a well-established person ready to leave his direct involvement in science and take up a new endeavor of a more administrative nature. Nevertheless, the powers that be soon realized that Martin was an excellent, if somewhat unconventional candidate who had enough energy to remain a topnotch scientist and to lead the journal in the difficult times ahead: he was offered the job. In the negotiations that followed, he insisted in getting the administrative structures that would allow him to improve the battered quality of the journal and to continue his scientific productivity. Today we are happy to see that he succeeded in both endeavors. The journal has since grown in size and considerably improved its quality. Martin Stutzmann's scientific output has continued and today he can be found listed among the 400 most cited physicists worldwide. According to the Institute of Scientific Information (ISI) he has published nearly 400 articles in source journals; they have been cited over 4600 times. His scientific visibility has been partly responsible for the success of the journal under his leadership. When he took over in 1995 the Impact Factors of physica status solidi (a) and (b) were about 0.5. Now they oscillate around 1.0. The journals occupy places 30 (a) and 29 (b) among the 57 condensed matter publications listed in the ISI. Six years ago these places were 34 (a) and 30 (b). The journal is even better placed with respect to the so-called cited half-life which is 8.2 years for pss (a) (place 16 among 57) and 6.7 years for pss (b) (place 20 among 57). Martin, of course, has contributed with his original publications to the success of the journal, having published 36 articles in pss(a) and 32 in pss(b). I would like to some of the editorial decisions implemented under Martin's leadership. They have been largely responsible for the quantitative improvements just described. Martin introduced international standards of peer review, usually involving two anonymous referees: The increase of the rejection rate from ca. 20% to 60% followed. He discontinued the Short Notes, which had become nearly irrelevant, and replaced them, in 1997 by Rapid Research Notes (today Rapid Research Letters) with especially strict reviewing rules and a rather attractive layout. Martin's participation in many international conferences and their organization gave him a handle to acquire the publication of conference proceedings. Organizing committees usually prefer publication in international journals rather than special books because of their guaranteed future availability in libraries and the partaking in the reviewing procedure. The journal became increasingly popular along these lines, a fact which moved Martin to launch in 2002 part (c) of the journal, devoted mainly, but not exclusively, to conference articles. Martin also introduced the publication of Feature Articles, topical issues, and the instrument of the Editor's Choice to highlight articles deemed to be especially interesting. He appointed Regional Editors (6 at this point) which represent the journal in important geographic regions. He also brought the journal online, a must these days. The upheavals that followed the collapse of most of the communist world, the rapid development of science in many emerging nations and the enhanced competitiveness, even in the developed countries, have not ebbed out. Some of them are particular damaging to the reputation of science in a world increasingly skeptical of its values. I am thinking of scientific misconduct and outright fraud, in the form of plagiarism and data fabrication. physica status solidi was also afflicted by this plague: after all, it happened in the best of families. Two of the most notorious offenders of the past decade, J. H. Schön and Y. Park, also visited physica status solidi. In two courageous editorials Martin Stutzmann and Stefan Hildebrandt (Managing Editor of the journal) rapidly exposed these cases of misconduct together with other cases in which there was also good reason to suspect misconduct. Some of the articles involved were rapidly retracted by the authors, others were not. It is reassuring to say that none of them had any impact worth mentioning (1,3 citations, mostly by the authors themselves or in the editorials just mentioned). Only few journal editors dared to convey to the readers a warning that some work of those authors may be faulty even if no air-tight proof was available. However, Martin and Stefan did. We wish that Martin will remain at the helm at least another decade, before he switches to research on the liquid state as practiced in Southern France. [source] Reminiscences of a journeyman scientist: Studies of thermoregulation in non-human primates and humansBIOELECTROMAGNETICS, Issue 8 2008Eleanor Reed Adair Abstract After graduating from Mount Holyoke College in 1948 where I majored in experimental psychology I worked at the College for 2 years with the Johns Hopkins Thermophysiological Unit. My graduate work later at the University of Wisconsin, centering on sensory psychology, culminated in my 1955 PhD thesis on human dark adaptation. I continued work in sensory psychology later with Neal Miller at Yale and then moved to the John B. Pierce Foundation,a Yale affiliate,where I began the studies of thermoregulation that constitute the center of my scientific career. Those studies were largely,later wholly,conducted using microwave energy as a thermal load and were thus published in Bioelectromagnetics even as I played an active role in the Bioelectromagnetics Society. In the beginning this work was centered on the responses of Squirrel Monkeys to thermal loads. Later, serving as Senior Scientist at the Air Force Research Laboratory at San Antonio, I completed an extensive analysis of thermal regulation in humans. I consider this work of special note inasmuch as the extraordinary human thermoregulatory ability was surely among the attributes that were paramount in initially separating humans from the other anthropoid primates.

[source] Shaman/Scientist: Jungian Insights for the Anthropological Study of ReligionETHOS, Issue 4 2001Associate Professor Karen A. Smyers Anthropology still regards the experience of religion the same way it did when its interpretive paradigm was based on "scientific objectivity." To understand this situation, the work of C. G. Jung is helpful in two ways. First, by exploring how anthropology has dismissed Jung as a cultural universalist and/or mystic, often without an actual consideration of his writings, we see how he signifies what the field defines itself against. Second, Jung's empirical forays into the religious worldview provide us with both methodological and descriptive insights about that realm in which many of our informants (and even some anthropologists) live. [source] Studying protein folding on the Grid: experiences using CHARMM on NPACI resources under LegionCONCURRENCY AND COMPUTATION: PRACTICE & EXPERIENCE, Issue 4 2004Anand Natrajan Abstract One benefit of a computational Grid is the ability to run high-performance applications over distributed resources simply and securely. We demonstrated this benefit with an experiment in which we studied the protein-folding process with the CHARMM molecular simulation package over a Grid managed by Legion, a Grid operating system. High-performance applications can take advantage of Grid resources if the Grid operating system provides both low-level functionality as well as high-level services. We describe the nature of services provided by Legion for high-performance applications. Our experiences indicate that human factors continue to play a crucial role in the configuration of Grid resources, underlying resources can be problematic, Grid services must tolerate underlying problems or inform the user, and high-level services must continue to evolve to meet user requirements. Our experiment not only helped a scientist perform an important study, but also showed the viability of an integrated approach such as Legion's for managing a Grid.

Adams SUMMARY., Dr. Herman Boerhaave (1668,1738) first described esophageal rupture and the subsequent mediastinal sepsis based upon his careful clinical and autopsy findings and hundreds of references have since been written about Boerhaave's syndrome. Several fine historical accounts of this brilliant scientist have been published over the years and he has received appropriate credit for his valuable contributions. But what about that unfortunate propositus that Dr. Boerhaave attended to, performed necropsy upon, and subsequently received acclaim with? Medical history pays inadequate regard to the Baron Jan Gerrit van Wassenaer heer van Rosenberg, Prefect of Rhineland and Grand Admiral of the Dutch Fleet. This figure was a nobleman and war hero at the peak of the Dutch Golden Age who played his role in steering the course of European history. Without this nobleman's heroic contemporaneous account, Boerhaave's celebrated impact on medical science would never have been realized. Therefore, we offer an overdue recitation of Admiral van Wassenaer's biography. Based on found precedent we propose that spontaneous rupture of the esophagus be henceforth referred to as the ,Boerhaave-van Wassenaer's syndrome'.

[source] At the birth of molecular radiation biology ,ENVIRONMENTAL AND MOLECULAR MUTAGENESIS, Issue 2-3 2001Raymond Devoret Abstract Rational thinking builds on feelings, too. This article starts with a tribute to Richard Setlow, an eminent scientist; it retraces as well some studies in molecular genetics that helped to understand basic questions of radiation biology. In the mid-1950s, the induction of a dormant virus (prophage) by irradiation of its host was an intriguing phenomenon. Soon, it was found that prophage induction results from the inactivation of the prophage repressor. Similarly, a score of induced cellular SOS functions were found to be induced when the LexA repressor is inactivated. Repressor inactivation involves the formation of a newly formed distinctive structure: a RecA-polymer wrapped around single-stranded DNA left by the arrest of replication at damaged sites. By touching this RecA nucleofilament, the LexA repressor is inactivated, triggering the sequential expression of SOS functions. The RecA nucleofilament acts as a chaperone, allowing recombinational repair to occur after nucleotide excision repair is over. The UmuD,C complex, synthesized slowly and parsimoniously, peaks at the end of recombinational repair, ready to be positioned at the tip of a RecA nucleofilament, placing the UmuD,C complex right at a lesion. At this location, UmuD,C prevents recombinational repair, and now acts as an error-prone paucimerase that fills the discontinuity opposite the damaged DNA. Finally, the elimination of lesions from the path of DNA polymerase, allows the resumption of DNA replication, and the SOS repair cycle switches to a normal cell cycle. Environ. Mol.

[source] Water-repellent soil and its relationship to granularity, surface roughness and hydrophobicity: a materials science viewEUROPEAN JOURNAL OF SOIL SCIENCE, Issue 4 2005G. McHale Summary Considerable soil water repellency has been observed at a wide range of locations worldwide. The soil exhibiting water repellency is found within the upper part of the soil profile. The reduced rate of water infiltration into these soils leads to severe runoff erosion, and reduction of plant growth. Soil water repellency is promoted by drying of soil, and can be induced by fire or intense heating of soil containing hydrophobic organic matter. Recent studies outside soil science have shown how enhancement of the natural water repellency of materials, both porous and granular, by surface texture (i.e. surface roughness, pattern and morphology) into super-hydrophobicity is possible. The similarities between these super-hydrophobic materials and observed properties of water-repellent soil are discussed from a non-soil scientist, materials-based perspective. A simple model is developed for a hydrophobic granular surface and it is shown that this can provide a mechanism for enhancement of soil water repellency through the relative size and spacing of grains and pores. The model provides a possible explanation for why soil water repellency should be more prevalent under dry conditions than wet. Consequences for water runoff, raindrop splash and soil erosion are discussed. [source] Germ Line Transformation of Mammals by Pronuclear MicroinjectionEXPERIMENTAL PHYSIOLOGY, Issue 6 2000T. Rülicke The most popular approach for generating transgenic mammals is the direct injection of transgenes into one pronucleus of a fertilized oocyte. In the past 15 years microinjection has been successfully applied in laboratory as well as in farm animals. The frequency of transgenic founders, although highly different between the species, is efficient enough to render this technique applicable to a wide range of mammals. The expression levels and patterns of a transgene are initially influenced by the construction of the transgene. However, the overall phenotype of a transgenic organism is influenced by several genetic and environmental factors. Due to the features of this technique not all of the genetic factors can be experimentally controlled by the scientist. In this article we will emphasize some peculiarities which have to be taken into account for the successful performance of transgenesis by pronuclear microinjection [source] A SHORT COMMENTARY ON TIMOTHY M. TIPPINS AND JEFFREY P. WITTMANN'S "EMPIRICAL AND ETHICAL PROBLEMS WITH CUSTODY RECOMMENDATIONSFAMILY COURT REVIEW, Issue 2 2005A Call for Clinical Humility, Judicial Vigilance" In this commentary, the call for clinical humility and judicial vigilance in custody recommendations is confirmed as valid and the Australian experience, where the child custody report writer has for some years been permitted to express an opinion on the ultimate issue, is considered. The inherent risks are briefly discussed, and the question of who of the judge and the social scientist might be better placed to decide the exquisitely difficult children's issues after family breakdown is touched upon. It suggests that a combination of the expert's opinion and judicial fact finding probably produces a result that is as good as it gets. But a greater danger is highlighted. It is the impact of the adversary system, and whether it is suitable in any event to these sensitive court decisions. [source] The Candida Genome Database: Facilitating research on Candida albicans molecular biologyFEMS YEAST RESEARCH, Issue 5 2006Maria C. Costanzo Abstract The Candida Genome Database (CGD; http://www.candidagenome.org) is a resource for information about the Candida albicans genomic sequence and the molecular biology of its encoded gene products. CGD collects and organizes data from the biological literature concerning C. albicans, and provides tools for viewing, searching, analysing, and downloading these data. CGD also serves as an organizing centre for the C. albicans research community, providing a gene-name registry, contact information, and research community news. This article describes the information contained in CGD and how to access it, either from the perspective of a bench scientist interested in the function of one or a few genes, or from the perspective of a biologist or bioinformatician interpreting large-scale functional genomic datasets.

[source] Neuroimaging of the developing brain: Taking "developing" seriouslyHUMAN BRAIN MAPPING, Issue 6 2010Annette Karmiloff-Smith Abstract With a few notable exceptions, many studies, be they behavioral, neuroimaging, or genetic, are snapshots that compare one child group to one adult group, which capture only two points in time and tell the scientist nothing about the mechanisms underlying neural trajectories over developmental time. Thus, a distinction needs to be drawn between child neuroimaging and developmental neuroimaging, the latter approach being relevant not just to children, but to adults and the ageing brain.
