Replication Data for: Self-constraining of meandering rivers
No full textMeandering rivers are abundantly present on earth, from the largest rivers to the smallest tributaries. The classical view of meandering rivers is a sinuous planform with rounded bends, which grow and migrate until they are cut off. However, many meandering rivers do not show lateral migration and have planforms that are much more complex than this classical view. Based on a detailed palaeogeographic study, we find that low-energy meandering rivers may develop complex planforms with sharp bends, while their self-formed deposits increasingly constrain the lateral mobility of the river channel. This finding is confirmed by data of 48 meandering river reaches of varied scale from around the world, which show that erosion-resistant floodplain deposits are preserved in the river banks when the river energy is below a critical threshold. This increases bank stability over time and thus enlarges the required energy needed to break out of the self-constraining tendency. Self-constraining thereby enhances resilience of the system, but highly non-linear increase in bank erosion will occur if river energy exceeds the critical threshold. Our study provides a novel explanation for river planforms and river dynamics and their responses to climatic changes
Variance in Response to Heat Treatment in Perkinsville Jasper
No full textabstract: The heat treatment of lithic raw material is a globally dispersed technology that improves the flaking quality of toolstone. While not all types of stone respond to heat treatment, many forms of microcrystalline silicates do, including jasper. Here, we aim to better understand how Perkinsville jasper responds to heat treatment. Perkinsville jasper occurs in the Perkinsville Valley of Yavapai County, Arizona, and was utilized prehistorically by the Prescott, Sinagua, and Hohokam cultures. For our study, we collected seven boulders of jasper from private land (with permission) in Yavapai County. These boulders were flintknapped into 74 spalls which were subsequently heated in an electric kiln using 20 treatment protocols with systematically varying combinations of maximum temperature and maximum heating times. Afterward, we compared multiple quantitative and qualitative characteristics of unheated and heated flakes taken from the same nodule pre- and post-heat treatment. Our heating protocol allows us to determine an ‘optimal heating context’ for Perkinsville jasper and to better understand how variation in time and temperature influences flaking quality of the stone. Lastly, this research develops an experimental reference dataset that can be used by other researchers studying raw material use and heat treatment in the Southwest United States. (abstract
Birds of Jasper National Park, Alberta, Canada
No full textJasper Park, with an area of approximately 4,200 square miles, is the largest accessible primeval wildlife sanctuary on this continent and as such its bird life is of the greatest interest. The meagre available records of earlier conditions indicate that noteworthy changes in the park\u27s avifauna have taken place in the last 50 years. There can be little doubt that other changes will take place during the years to come. For this reason, then, if for no other, it seems desirable that as complete a record as possible of the current situation be made, for only against it can the significance of future trends be evaluated.
In 1943 the author spent a week in the Athabasca Valley in mid-April, and in July, August, and September travelled the south boundary trail, entering over Nigel Pass and passing by way of Jonas Pass and Indian Pass to the Brazeau icefields. From there in to Jasper the same route was followed as used by Clarke on his way out. The north boundary was ridden from Devona to Robson by way of Snake Indian Pass.
Field work of 1944 covered much of the same areas as that of the previous year. Beginning on May 2, the author, accompanied by James Hatter, ascended the Snake Indian to Blue Creek and Topaz Lake, worked the Athabasca and Miette Valleys trom Yellowhead Pass to East Gate and the Banff-Jasper Highway area, and finally travelled the south boundary by way of Poboktan Pass, Brazeau River, Southesk River and Pass, and down the Rocky to Jacques Lake. This time the Maligne Lake area was visited and the lake explored along its entire length. In December of the same year observations were made at Jasper and Devona. Additional field work was carried on in the Athabasca Valley in July, 1945 and in May and June, 1946
Interview with the author
No full textA change has come to popular media. Every day, we are digitally invited into the homes and
lives of the creators whose work we love. We are pushed to become attached to them as we
become attached to their work. How can we as viewers healthily interact with the creators whose
work we enjoy, and how can we as creators healthily interact with the people that enjoy our
work? How intimate can we become? How intimate should we become? What harm can we do to
each other? Interview with the Author is a visual novel that asks its players to engage with these
questions while taking the role of web columnist Reed Knightly as they interview science fiction
author Arthur Wright. Stemming from a semester-long inquiry into the subject of parasocial
relationships, Death of the Author, and the intersection of the two theories, Interview lets its
players can ask Arthur a variety of questions related to topics like their professional work, their
fandom, and their time as a fanfiction writer. The answers they receive dynamically shift
depending on the player’s perceived interest or disinterest in parasocial connections between
authors, readers and fictional characters. Interview represents a continued exploration of the
subject of communication in my work, and of the way individuals and constructs build
connections with one another.Thesis (B.?)Honors Colleg
Animation of data link protocols using JASPER tool
No full textV diplomski nalogi smo implementirali protokol z oddajo z mirovanjem in protokol s selektivno ponovno oddajo iz učbenika Computer Networks A. S. Tanenbauma s pomočjo orodja JASPER z namenom, prikazati obnašanje protokolov z animacijo. Najprej smo na kratko opisali vlogo in namen animacije protokolov ter navedli nekatera znana animacijska orodja. V jedru naloge smo najprej na splošno opisali orodje JASPER, njegovo zgradbo in koncept delovanja. Nato smo opisali oba protokola ter preslikavo njune implementacije iz programskega jezika C, kot si jo je zamislil avtor učbenika, v programski jezik našega orodja, javo. Pravilno delovanje razvite kode smo prikazali s podajo posnetkov animacije ter nekaterih možnih scenarijev v delovanju obeh protokolov.In this diploma thesis, we implemented an idle RQ protocol and a selective repeat protocol from A. S. Tanenbaum\u27s textbook Computer Networks by using JASPER tool with the purpose to show protocol behavior with animation. First, we briefly described the role and purpose of protocol animation and stated some well-known animation tools. In the central part of our thesis, we first provided a general description of JASPER tool, its structure and concept of operation. We then described both protocols and the mapping of their implementation from C programming language as suggested by the author of the textbook into Java, the programming language of our tool. We demonstrated the proper functioning of the developed code by presenting snapshots of the animation and some possible scenarios from the operation of the two protocols
Temperature dependence on the electron paramagnetic resonance spectra of natural jasper from Taroko Gorge (Taiwan)
No full textStructural properties of natural jasper from Taroko Gorge (Taiwan) have been investigated by means of powder X-ray diffraction, electron paramagnetic resonance (EPR) and Fourier transform infrared spectroscopic techniques. The EPR spectrum at room temperature exhibits a sharp resonance signal at g = 2.007 and two more resonance signals centered at g a parts per thousand 4.3 and 14.0. The resonance signal at g = 2.007 has been attributed to the E' center and is related to a natural radiation-induced paramagnetic defect. Two more resonance signals centered at g a parts per thousand 4.3 and 14.0 are characteristic of Fe(3+) ions. The EPR spectra recorded at room temperature of jasper samples, heat-treated at temperatures ranging from 473 to 1,473 K exhibit marked temperature dependence. The resonance signal corresponding to E' center disappears at elevated temperatures. A broad, intense resonance signal centered at g a parts per thousand 2.0 appears at elevated temperatures. This resonance signal is a characteristic of Fe(3+) ions, which are present as hematite in the jasper sample. The intensity of the resonance signal becomes dominant at elevated temperatures at a parts per thousand yen873 K, masking g a parts per thousand 4.3 and g a parts per thousand 14.0 resonance signals. The EPR spectra of jasper heat-treated at 673 K have been recorded at temperatures between 123 and 296 K. The population of spin levels (N) has been calculated for the broad g a parts per thousand 2.0 resonance signal. It is found that N decreases with decreasing temperature. The linewidth (Delta H) of g a parts per thousand 2.0 resonance signal of the heat-treated jasper is found to increase with decreasing temperature. This has been attributed to spin-spin interaction of the Fe(3+) ions present in the form of hematite in the studied jasper sample
