    Vogt-Koyanagi-Harada disease, a severe bilateral granulomatous intraocular inflammation associated with serous retinal detachments, disk edema, and vitritis, with eventual development of a sunset glow fundus, is an autoimmune inflammatory condition mediated by T cells that target melanocytes in individuals susceptible to the disease. Vogt-Koyanagi-Harada disease presents clinically in 4 different phases: prodromal, uveitic, convalescent, and recurrent, with extraocular manifestations including headache, meningismus, hearing loss, poliosis, and vitiligo, to varying degrees. There have been considerable advances in imaging modalities resulting in earlier diagnosis and improved understanding of this disease. Ocular coherence tomography has replaced other imaging modalities in the diagnosis of acute and chronic Vogt-Koyanagi-Harada disease by revealing exudative detachments of the retina in the acute stage, along with choroidal thickening and demonstrating choroidal thinning in the chronic stage. Treatment of this disease is initially with corticosteroids, with a transition to immunomodulatory drugs for long-term control. Patients with Vogt-Koyanagi-Harada disease can have good final outcomes if treated promptly and aggressively and thus avoid complications such as sunset glow fundus, cataracts, glaucoma, subretinal fibrosis, and choroidal neovascularization.

    The human cerebral cortex contains numerous myelinated fibres, the arrangement and density of which is by no means homogeneous throughout the cortex. Local differences in the spatial organization of these fibres render it possible to recognize areas with a different myeloarchitecture. The neuroanatomical subdiscipline aimed at the identification and delineation of such areas is known as myeloarchitectonics. During the period extending from 1910 to 1970, Oscar and Cécile Vogt and their numerous collaborators (The Vogt-Vogt school) published a large number of myeloarchitectonic studies on the cortex of the various lobes of the human cerebrum. Recently, one of us (Nieuwenhuys in Brain Struct Funct 218: 303-352, 2013) extensively reviewed these studies. It was concluded that the data available are adequate and sufficient for the composition of a myeloarchitectonic map of the entire human neocortex. The present paper is devoted to the creation of this map. Because the data provided by the Vogt-Vogt school are derived from many different brains, a standard brain had to be introduced to which all data available could be transferred. As such, the colin27 structural scan, aligned to the MNI305 template was selected. The procedure employed in this transfer involved computer-aided transformations of the lobar maps available in the literature, to the corresponding regions of the standard brain, as well as local adjustments in the border zones of the various lobes. The resultant map includes 180 myeloarchitectonic areas, 64 frontal, 30 parietal, 6 insular, 17 occipital and 63 temporal. The designation of the various areas with simple Arabic numbers, introduced by Oscar Vogt for the frontal and parietal cortices, has been extended over the entire neocortex. It may be expected that combination of the myeloarchitectonic data of the Vogt-Vogt school, as expressed in our map, with the results of the detailed cytoarchitectonic and receptor architectonic studies of Karl Zilles and

    VogtKoyanagi-Harada (VKH) is a rare syndrome affecting tissues with melanocytes. The possibility that VKH syndrome has an autoimmune pathogenesis is supported by the high frequency of human leukocyte antigen-DR4 commonly associated with other autoimmune diseases. Eyes are the main affected organ, resulting in blindness. Brain disease as a late onset event is extremely rare. Here, we are reporting a 57-year-old woman with previously diagnosed VKH syndrome, presenting with a late-onset brain encephalopathy.

    Vogt-Koyanagi-Harada (VKH) is a rare syndrome affecting tissues containing melanocytes. The possibility of its autoimmune pathogenesis is supported by high frequent HLA-DR4 presentation, commonly associated with other autoimmune diseases. Eyes are the main affected organs, resulting in blindness. Brain disease is a late-onset event, and is extremely rare. Here, we are reporting a 57-year-old woman, a known case of VKH syndrome, presenting with brain encephalopathy several decades after the initial presentation. We think this long period between initial presentation and presentation of encephalopathy due to VKH syndrome has not been described before. She was treated with corticosteroids and discharged home with a good general condition. PMID:24753681

  11. The Henry Problem Revisited

    2006-12-01

    We have modeled laboratory experiments of saltwater intrusion in a configuration resembling the so-called Henry Problem using TOUGH2/EOS7. The experiment differs from the Henry Problem in that the freshwater boundary condition is that of Dirichlet, a difference that is not expected to affect the overall results very much. The simulation matched the saltwater wedge profile of the experiment, the main feature of which was the sharp interface (lack of dispersion) between the freshwater and saltwater. Prior solutions of the Henry Problem show a wide transition zone between freshwater and saltwater arising from the use of a large dispersion coefficient. Henry attributed the large dispersion to the effect of tidally induced motion. In our simulation, we imposed a time-varying sinusoidal boundary condition to see if a larger transition zone can be created without using a larger dispersion coefficient. However, for the parameters used we were not able to do so. It is still plausible that the wide transition zone observed at Biscayne Bay (and as modeled in the Henry Problem) is caused by a particular formation heterogeneity and transient effects. Our analysis, based on a laboratory experiment and accompanying modeling, suggests that dispersion is quite limited. Nonetheless, we question the validity of the use of a large dispersion coefficient where the groundwater velocity is very low, or where the flow is in the opposite direction of the concentration gradient.

    "Can we do anything for you?" The question was embarrassing. Henry had been poked and prodded and preserved far beyond his wishes. In a medical system that scorns comfort care, a resident physician is troubled by the case of an elderly man with poor quality of life. An awkward attempt at a Boy Scout service project emphasizes how poorly we comfort the terminally ill despite modern technology and interventionalism.

    Richardson, Ruth

    2016-03-01

    The first edition of Anatomy Descriptive and Surgical (1858) was greeted with accolades, but also provoked serious controversy concerning Henry Gray's failure to acknowledge the work of earlier anatomists. A review in the Medical Times (1859) accused Gray of intellectual theft. The journal took the unusual step of substantiating its indictment by publishing twenty parallel texts from Gray and from a pre-existing textbook, Quain's Anatomy. At the recent "Vesalius Continuum" conference in Zakynthos, Greece (2014) Professor Brion Benninger disputed the theft by announcing from the floor the results of a computer analysis of both texts, which he reported exonerated Gray by revealing no evidence of plagiarism. The analysis has not been forthcoming, however, despite requests. Here the historian of Gray's Anatomy supplements the argument set out in the Medical Times 150 years ago with data suggesting unwelcome personality traits in Henry Gray, and demonstrating the utility of others' work to his professional advancement. Fair dealing in the world of anatomy and indeed the genuineness of the lustre of medical fame are important matters, but whether quantitative evidence has anything to add to the discussion concerning Gray's probity can be assessed only if Benninger makes public his computer analysis.

    Joseph Henry (1797-1878) is best known for his work in electromagnetism and as the first secretary of the Smithsonian Institution. But he was also a pioneer solar physicist, an early advocate of US participation in astrophysics, and a facilitator of international cooperation in astronomy. This paper will briefly trace his role in the development of the US astronomical community from the time he taught astronomy at Princeton in the 1830s through his death, focusing on failed efforts to persuade US astronomers and patrons of astronomy that the best path for US astronomy should be astrophysics. He thought that the US could make a more significant contribution to astronomy science by striking out on a less travelled path rather than competing with the established European observatories.

    Vogt-Koyanagi-Harada disease is characterized by marked bilateral uveitis associated with symmetric vitiligo, alopecia, poliosis and dysacousia. Linear immunoglobulin (Ig)A bullous dermatosis (LABD) is characterized by small, tense, subepidermal bullae caused by IgA type autoantibody targeting the basal lamina. LABD patients sometimes show coexistence of IgG type autoantibody, termed linear IgA/IgG bullous dermatosis (LAGBD). We reported a 35-year-old Japanese male case of combined LAGBD and Vogt-Koyanagi-Harada disease. His human leukocyte antigen typing was -A24, B52, C*1202, DR*1502, DQ*0601. Immunoblot revealed that patient sera reacted to both 180- and 230-kDa proteins at the IgA and IgG level. Because Vogt-Koyanagi-Harada disease and LABD are reported to be associated with other autoimmune diseases, it is probable that Vogt-Koyanagi-Harada disease and LAGBD in our case may be associated with each other in the pathomechanism. However, we cannot exclude the possibility of this being mere coincidence.

    Purpose. This study explored the efficacy of optical coherence tomography (OCT) as a high-resolution, noncontact method for imaging the palisades of Vogt by correlating OCT and confocal microscopy images. Methods. Human limbal rims were acquired and imaged with OCT and confocal microscopy. The area of the epithelial basement membrane in each of these sets was digitally reconstructed, and the models were compared. Results. OCT identified the palisades within the limbus and exhibited excellent structural correlation with immunostained tissue imaged by confocal microscopy. Conclusions. OCT successfully identified the limbal palisades of Vogt that constitute the corneal epithelial stem cell niche. These findings offer the exciting potential to characterize the architecture of the palisades in vivo, to harvest stem cells for transplantation more accurately, to track palisade structure for better diagnosis, follow-up and staging of treatment, and to assess and intervene in the progression of stem cell depletion by monitoring changes in the structure of the palisades.

  1. Joseph Henry and the Telegraph

    1997-04-01

    Morse's telegraph rested upon three scientific advances which occured between 1800 and 1830: the development of battery technology, the formulation of laws governing the behavior of electrical components in circuits, and the discovery of electromagnetic phenomena. Joseph Henry was crucial to the development of the early telegraph. His work on electromagnetism made it possible for the electric current to manifest itself as useful mechanical work. Henry developed electromagnets of sufficient lifting power, but which drew relatively small currents; these magnets were the heart of Morse's telegraph receiver. Morse also used electromagnets as relays, which allowed him to transmit signals over great distances. Morse often acknowledged his debt to Henry, and the two enjoyed a cordial working relationship until the mid-1840s. But during the bitter and protracted litigation over Morse's patent, Henry testified (unwillingly, he claimed) against the inventor. This began a lifelong quarrel between the two men, the specifics of which were tedious and petty. In general terms, however, their conflict arose over different notions regarding scientific discovery and technological innovation.

    We describe focal choroidal excavation (FCE) in a case of Vogt-Koyanagi-Harada (VKH) disease and compare the findings with different chorioretinal conditions. A 55-year-old man was diagnosed with VKH based on panuveitis and exudative retinal detachments. Spectral-domain optical coherence tomography demonstrated a dome-shaped protrusion with a nonconforming pattern at the fovea, which had been detected as a conforming pattern 1 year before the onset. The FCE pattern returned into a conforming pattern following corticosteroid therapy. These findings suggest that the natively existent FCE could be affected by pathophysiological changes of VKH as well as other chorioretinal conditions.

    A post-traumatic partial tear of the flexor hallucis longus tendon at the master knot of Henry and the resultant fibrosis of the knot can result in pain at the medial foot arch or posteromedial ankle pain with trigger hallux. Open debridement of the master knot of Henry is indicated if the symptoms do not improve with nonoperative treatment. The open procedure requires extensive soft-tissue dissection because the master knot of Henry is a deep structure. Endoscopic release of the master knot of Henry is an alternative to the open procedure and has the advantage of less surgical trauma and potential for less chance of recurrence of fibrosis of the master knot of Henry.

    1974-01-01

    A systematic study is made of the number and types of solutions of the equilibrium equations of stellar structure, in the case of homogeneous stars of Population I over the mass range 2-1000 solar masses, with four different opacity representations. A variant of the usual fitting method permits the simultaneous investigation of convergence and tendency toward multiplicity of the solutions. Quadratic interpolation and extrapolation of Carson's new opacity tables produces a very large opacity at low temperatures that greatly affects the loose outer layers of massive stars, while leaving the cores practically unaffected. As a result, over a small mass range, well above 100 solar masses, triple solutions exist, always near an effective temperature of log Te = 4.73. A simple classification of the known exceptions to the Vogt-Russell theorem on the uniqueness of stellar structure is given.

    If these pages fail to give a correct account of the structure of the Henry Mountains the fault is mine and I have no excuse. In all the earlier exploration of the Rocky Mountain Region, as well as in much of the more recent survey, the geologist has merely accompanied the geographer and has had no voice in the determination of either the route or the rate of travel. When the structure of a mountain was in doubt he was rarely able to visit the points which should resolve the doubt, but was compelled to turn regretfully away. Not so in the survey of the Henry Mountains. Geological exploration had shown that they were well disposed for examination, and that they promised to give the key to a type of structure which was at best obscurely known; and I was sent by Professor Powell to make a study of them, without restriction as to my order or method. I was limited only in time, the snow stopping my work two months after it was begun. Two months would be far too short a period in which to survey a thousand square miles in Pennsylvania or Illinois, but among the Colorado Plateaus it proved sufficient. A few comprehensive views from mountain tops gave the general distribution of the formations, and the remainder of the time was spent in the examination of the localities which best displayed the peculiar features of the structure. So thorough was the display and so satisfactory the examination, that in preparing my report I have felt less than ever before the desire to revisit the field and prove my conclusions by more extended observation.

    1997-12-31

    A study was conducted to define parameters relating to the use of a down hole submersible photoionization detector (PID) probe to measure volatile organic compounds (VOCs) in an artificial headspace. The partitioning of toluene and trichloroethylene between water and air was studied as a function of analyte concentration and water temperature. The Henry`s law constant governing this partitioning represents an ideal condition at infinite dilution for a particular temperature. The results show that in practice. this partitioning is far from ideal. Conditions resulting in apparent, practical deviations from Henry`s law include temperature and VOC concentration. Thus, a single value of Henry`s law constant for a particular VOC such as toluene can provide only an approximation of concentration in the field. Detector response in saturated humidity environments as a function of water temperature and analyte concentration was studied also.

    Merritt, David; Gottesman, Stephen T.

    2004-12-01

    Henry Emil Kandrup died on 18 October 2003 at his home in Gainesville Florida. Henry was a theoretical astrophysicist specializing in the application of chaotic dynamics to stellar systems. At the time of his death, Henry was a Professor at the University of Florida where he had taught for 13 years. Henry was born in Manhasset, New York on July 24, 1955 and spent most of his childhood in Great Neck. His parents, Jytte and Fred, were immigrants from Denmark where his father had worked as a silver smith. Henry was a precocious child, skipping both third and fifth grades. With the help of Sidney Spivack, a professor of sociology at Columbia University, his parents enrolled Henry in the Brooks Preparatory School in Andover, Massachusetts. After graduating at age 16, Henry enrolled at Cornell, transferring to Princeton the following year. Henry's parents adored their only child and worked hard to provide him with intellectual opportunities. Henry became an accomplished musician (organ, piano, French horn) and linguist (English, Danish, German) and was a passionate devotee of opera and ballet. Henry received his PhD in 1980 from the University of Chicago, where his thesis advisor was James Ipser. He taught at Oakland University in Michigan and Syracuse University in New York before coming to the University of Florida in 1990. Henry was sui generis. He shunned conventionality in his personal appearance and in his public demeanor, and always chose forthrightness and candor over polite silence. But to those of us who knew Henry well, his bluntness was a reflection of his intellectual consistency. Henry always said exactly what he thought, both in his published work and his public presentations, and never compromised himself for the sake of appearances. Nothing that he said or wrote was less than fully thought out. Henry's PhD thesis was entitled "Stochastic Problems in Stellar Dynamics," and most of his subsequent research was in this field.

    AIM To review all cases of Vogt-Koyanagi-Harada (VKH) disease in an Inflammatory Eye Disease Service in Argentina and to describe the clinical profile and outcomes of treatment. METHODS The records from patients with VKH disease between January 1980 and December 2008 were retrospectively analyzed for clinical profile, complications, and treatment. Patients were classified according to their initial treatment in group 1: high corticosteroid dose [≥1 mg/(kg·d)] within 2wk of illness onset; group 2: high corticosteroid dose, 2 to 4wk of onset and group 3: patients who received the high dose after 1mo of illness onset, patients who received lower oral doses than 1 mg/(kg·d) without regarding the time of beginning of the disease. RESULTS A total of 210 eyes of 105 patients were included. The mean age at presentation was 32.6±13y (range: 10-74y), and 86.7% were female. The mean duration of follow up was 144±96.6mo. Patients in the group 1 had significantly higher visual acuity than the other groups (P<0.0001), none had (loss of, or no) light perception at the end of follow up, whereas 24.7% patients in group 3 ended in light perception (P<0.004). CONCLUSION Patients with early high dose corticosteroid treatment have better visual acuity and fewer complications. Proper timing in referral and treatment is critical for better visual outcome in VKH disease. PMID:28149784

    Vogt-Koyanagi-Harada's (VKH) disease has been reported to be rare in sub-Saharan Africa. Two Nigerians with the disease are presented in this report. The first patient, a 32-year-old pregnant Nigerian woman presented with a 1-month history of bilateral blurring of vision, persistent headache, and alopecia. Presenting visual acuity was 1 m counting fingers in both eyes. Examination revealed vitiligo and poliosis with bilateral panuveitis as well as bilateral exudative retinal detachment. A clinical assessment of complete VKH disease was made. The patient commenced systemic and topical steroids that resulted in remarkable recovery of vision and control of inflammation. The second patient, a 56-year-old Nigerian woman presented with severe headache, tinnitus, and visual loss in both eyes of 2 weeks duration. There was associated redness of both eyes and photophobia. Examination showed visual acuity of Hand motion (HM) and counting fingers at 1 meter (CF). in the right and left eye, respectively, with bilateral panuveitis and bilateral exudative retinal detachment. Subsequent follow-up showed poliosis, vitiligo, and sunsetting fundus appearance. The patient improved with systemic and topical corticosteroids. Developing a high index of suspicion is necessary in diagnosing VKH disease, even in sub-Saharan Africa. Prompt institution of appropriate treatment prevents blindness.

    Purpose The purposes of this study are first, to determine if the palisades of Vogt (POV) are present or absent in cases of congenital corneal opacification (CCO) by using spectral domain ocular coherence tomography (SD-OCT), and second, in those cases already undergoing penetrating keratoplasty (PKP), to see whether the absence or presence of POV corresponds to re-epithelialization following transplant. Methods This was a retrospective case review of 20 eyes (10 normal, 10 with CCO) evaluated with SD-OCT. The operator was masked to the clinician’s assessment of the ocular surface. In those cases where the decision to perform PKP had already been made, the correlation between POV presence or absence and posttransplant graft epithelialization was determined. Results All cases were imaged without adverse event. Nine eyes showed some evidence of POV and corresponding vasculature. Eight of 10 affected eyes underwent PKP, and subsequently 7 eyes epithelialized and 2 showed some peripheral neovascularization. The one eye that showed no signs of POV was the one that failed to epithelialize. All control subjects had consistent and regular POV. Conclusions Congenital corneal opacification is rare, and this study shows that at least some POV are present in the majority of cases of CCO. However, the palisades may not be entirely normal compared to age-matched controls. When there was absence of POV in a case of CCO, there was immediate and complete failure of epithelialization.

  18. Joseph Henry's Conception of Scientific Knowledge

    Theerman, Paul

    1997-04-01

    Joseph Henry, America's premier physicist and physics teacher in the mid-nineteenth century, had decided views of scientific knowledge. These were expressed in two ways. First of all, scientific knowledge led to moral betterment. Thus the study of science was a morally good thing. This was not only because it led to the contemplation of God's creation, which was a standard reason justifying the study of science dating from the Scientific Revolution and even earlier. More importantly, the study of science itself was a moral discipline, imparting to scientists the habits and virtues of truthfulness, respect for others, care and diligence, and the discernment of meaningful patterns from experience. The moral ideals of science were expressed most strongly in Henry's upholding the international "Republic of Science"; conversely, cheapening science was a sign of moral failure. Second, for Henry and his generation, science provided a path to sure truth, separate from falsehood of both the politics and the quackery that characterized mid-century public life. Henry promoted this in his championing of the Smithsonian Institution a scientific establishment, against the ideas of others who wanted to make it a literary establishment or a training school for teachers. For Henry, the Smithsonian's scientific reputation would be established by relying on careful peer review in its publications, and supporting established scientists to write authoritative popular works. The purpose of both these activities was to raise the profile of science in the United States and further establish science and the scientific method as a guide to public life.

    We describe a case with macular hole (MH) associated with Vogt-Koyanagi-Harada (VKH) disease. A 71-year-old Japanese woman presented with visual loss and headaches. The best-corrected visual acuity (BCVA) was 0.02 in the right eye (RE) and 0.1 in the left eye (LE). The patient was diagnosed with VKH based on circumferential choroidal detachments, multiple serous retinal detachments, and optic disc hyperemia. The multiple serous retinal detachments improved with high-dose corticosteroid therapy and gradual tapering. The BCVA was recovered to 1.2/0.7 in the RE/LE. Six weeks after the initial administration of steroid, vitreomacular traction was found by optical coherence tomography in the LE, which progressed to stage 4 MH with the BCVA of 0.2 in the LE. Twenty-three weeks after the initial treatment, vitrectomy was performed with the standard surgical procedures, including inner limiting membrane peeling around the fovea and air tamponade. The MH was closed successfully and the BCVA was 0.4 in the LE 5 weeks after the vitrectomy. This is the first report of a case with MH secondary to the acute uveitic stage of VKH. Successful closure of MH was achieved with the standard surgical intervention for an idiopathic MH. To conclude, at the early stage of VKH, there is a possibility of MH formation due to the rapid progress of vitreous traction following the inflammation, and the surgical procedure could be effective to resolve this secondary disorder.

    Vogt-Koyanagi-Harada (VKH) disease is one of the major vision-threatening diseases in certain populations, such as Asians, native Americans, Hispanics and Middle Easterners. It is characterized by bilateral uveitis that is frequently associated with neurological (meningeal), auditory, and integumentary manifestations. Although the etiology and pathogenesis of VKH disease need to be further elucidated, it is widely accepted that the clinical manifestations are caused by an autoimmune response directed against melanin associated antigens in the target organs, i.e. the eye, inner ear, meninges and skin. In the past decades, accumulating evidence has shown that genetic factors, including VKH disease specific risk factors (HLA-DR4) and general risk factors for immune mediated diseases (IL-23R), dysfunction of immune responses, including the innate and adaptive immune system and environmental triggering factors are all involved in the development of VKH disease. Clinically, the criteria of diagnosis for VKH disease have been further improved by the employment of novel imaging techniques for the eye. For the treatment, early and adequate corticosteroids are still the mainstream regime for the disease. However, immunosuppressive and biological agents have shown benefit for the treatment of VKH disease, especially for those patients not responding to corticosteroids. This review is focused on our current knowledge of VKH disease, especially for the diagnosis, pathogenesis (genetic factors and immune mechanisms), ancillary tests and treatment. A better understanding of the role of microbiome composition, genetic basis and ongoing immune processes along with the development of novel biomarkers and objective quantitative assays to monitor intraocular inflammation are needed to improve current management of VKH patients.

    We have investigated whether a Vogt-Koyanagi-Harada (VKH)-like disease can be induced in Akita dogs by immunizing them with tyrosinase related protein 1 (TRP1), and compared the alterations induced to those of Akita dogs with a spontaneously occurring disease that resembles human VKH disease. Two Akita dogs were immunized with a peptide mixture of human TRP1. The changes in the eyes were followed by slit-lamp biomicroscopy, ophthalmoscopy, and fluorescein angiography (FA). The eyes, skin, and brains were studied by standard histological methods at about 20 months after the first immunization in one dog (dog 1), and at 3 weeks after the second immunization in the second dog (dog 2). Both dogs developed chorioretinal disease 3-4 weeks after the first immunization. Many inflammatory cells infiltrated into the anterior chamber and anterior vitreous. The fundus showed geographic, multifocal exudative retinal detachments. Multifocal leakages of fluorescein were detected from the choroid. Histologically, exudative retinal detachment was present, and inflammatory cells were seen in the subretinal space in the eyes of dog 2 taken three weeks after the second immunization. The choroid was thickened by the infiltration of inflammatory cells in some lesions. Dalen-Fuchs nodules were seen in the eye of dog 2. Depigmentation, pigment dispersion, and infiltration of many inflammatory cells around hair follicles and vessels were seen in the skin taken three weeks post-immunization. The clinical course and changes in the eyes and skin were very similar to those seen in the Akita dogs with spontaneously occurring VKH disease. We concluded that a VKH-like disease had been induced in these dogs, and this supports the tentative conclusion that the spontaneously occurring chorioretinal disease in Akita dogs is VKH disease.

  11. Contaminant Monitoring Strategy for Henrys Lake, Idaho

    1992-12-01

    Henrys Lake, located in southeastern Idaho, is a large, shallow lake (6,600 acres, {approx} 17.1 feet maximum depth) located at 6,472 feet elevation in Fremont Co., Idaho at the headwaters of the Henrys Fork of the Snake River. The upper watershed is comprised of high mountains of the Targhee National Forest and the lakeshore is surrounded by extensive flats and wetlands, which are mostly privately owned. The lake has been dammed since 1922, and the upper 12 feet of the lake waters are allocated for downriver use. Henrys Lake is a naturally productive lake supporting a nationally recognized ''Blue Ribbon'' trout fishery. There is concern that increasing housing development and cattle grazing may accelerate eutrophication and result in winter and early spring fish kills. There has not been a recent thorough assessment of lake water quality. However, the Department of Environmental Quality (DEQ) is currently conducting a study of water quality on Henrys Lake and tributary streams. Septic systems and lawn runoff from housing developments on the north, west, and southwest shores could potentially contribute to the nutrient enrichment of the lake. Many houses are on steep hillsides where runoff from lawns, driveways, etc. drain into wetland flats along the lake or directly into the lake. In addition, seepage from septic systems (drainfields) drain directly into the wetlands enter groundwater areas that seep into the lake. Cattle grazing along the lake margin, riparian areas, and uplands is likely accelerating erosion and nutrient enrichment. Also, cattle grazing along riparian areas likely adds to nutrient enrichment of the lake through subsurface flow and direct runoff. Stream bank and lakeshore erosion may also accelerate eutrophication by increasing the sedimentation of the lake. Approximately nine streams feed the lake (see map), but flows are often severely reduced or completely eliminated due to irrigation diversion. In addition, subsurface flows can occur as a

    BACKGROUND: Henry Norman Bethune is one of the most exciting and incredible surgeons that Canada has ever produced. Indeed, he is often characterized as one of the world’s best-known surgeons. He was an innovator and his scientific contributions have stood the test of time. In Canada, he will forever be remembered as a social activist committed to the welfare of the poor and to the reform of the health care system. In the People’s Republic of China, he is idolized and remains the only foreigner to ever become a national hero. OBJECTIVE: To detail the numerous and significant achievements of Henry Norman Bethune in the field of thoracic surgery and as a social activist and describe his heroic war-time actions on the battlefields of both Spain and China. METHOD: Information was gathered through the reading of the numerous publications written about the life and work of Bethune, interviews with knowledgeable people from Canadian and Chinese universities, analysis of Bethune’s own publications, and extensive experience of one of the authors in China. RESULTS: In the social sense, Henry Norman Bethune had a difficult personality, but he was deeply caring about the plight of his patients, especially the poor. As a thoracic surgeon, he could be ingenious, thoughtful and effective but he could also be abrasive, restless and temperamental. His scientific contributions were sound and, at the time, gained worldwide attention. As an activist, he led a crusade to reform the Canadian health care system, demanding free health care for all. His outstanding work during the Spanish Civil War, where he organized the first ever mobile blood transfusion unit, and during the Sino-Japanese war, where he was totally committed to the welfare of both soldiers and civilian population, were deliberate acts of resistance against Fascist onslaught and enthusiasm for the Communist cause. CONCLUSIONS: Henry Norman Bethune was unconventional and a revolutionary, but he was brilliant. He will

    1997-04-01

    On different sides of the Atlantic but about the same time, Michael Faraday and Joseph Henry announced success in a quest that had preoccupied the scientific community for a decade: coaxing electricity from magnetism. "Mutual induction," what Faraday and Henry had identified in the early 1830s, would turn out to be not only a foundational concept in the physics of electricity and magnetism but also the principle behind the technology of electrical transformers and generators--two mainstays of industrialization. Although Faraday's breakthrough in London and Henry's in Albany might appear to be classic examples of "independent discovery," they were not. The two natural philosophers shared a similar orientation toward their research and, moreover, a distinctive laboratory instrument: Henry's new, powerful electromagnet. Thus, the story of Henry's and Faraday's search for induction illuminates not only the workings of Victorian science but also the crucial part that an instrument--the unadorned hardware--can play in scientific inquiry. Albert Moyer takes this story from his biography of Joseph Henry that Smithsonian Institution Press is about to publish in commemoration of the 200th anniversary of Henry's birth. The biography focuses on Henry's early and middle years, 1797-1847, from his emergence as America's foremost physical scientist to his election as the Smithsonian Institution's first director.

    Aqueous solubilities, n-octanol/water partition coefficients (K{sub ow}S), and Henry`s law constants were determined for a range of polycyclic aromatic hydrocarbons (PAHs) using a generator-column, slow-stirring, and gas-purge method, respectively. The currently obtained data were compared to available literature data. For seven of the PAHs no K{sub ow}S previously were determined with the slow-stirring method. For four of the PAHs the present study reports the first experimental Henry`s law constants. Relationships between subcooled liquid solubilities, K{sub ow}S, and Henry`s law constants as a function of molar volume are discussed. A consistent data set was obtained, for which an excellent correlation was found between subcooled liquid solubility and molar volume. A linear fit did not accurately describe the relationship between log K{sub ow} and molar volume. This is probably due to a decreasing solubility in n-octanol with increasing molar volume. Finally, a high correlation was found between Henry`s law constant and molar volume. The presently obtained dataset can be used to predict the fate and behavior of unsubstituted homocyclic PAHs.

    Henry Norris Russell, one of the most influential American astronomers of the first half of the 20th Century, had a special place in his heart for the Lowell Observatory. Although privately critical of the founder for his pronouncements about life on Mars and the superiority of the Mars Hill observing site, he always supported the Observatory in public and professional circles. He staunchly supported Tombaugh's detection of a planet as leading from Lowell's prediction, and always promoted V. M. Slipher's spectroscopic investigations of planetary and stellar phenomena. But how did he react to Slipher's puzzling detection of the extreme radial velocities of spiral nebulae starting in 1912, and how did he regard the extension and interpretation of those observations by Hubble and others in following decades? Here we describe the arc of Russell's reactions, dating from Slipher's first detection, as an indicator of how mainstream stellar astronomers reacted to the concept of an expanding universe.

    Henry Albers, professor of astronomy at Vassar College for over thirty years, died March 29, 2009, in Fairhope, Alabama. For his work at Vassar, where he held the Maria Mitchell Chair, Albers received the first Maria Mitchell Women in Science Award for his inspiration of women astronomers. He said "In the final analysis it is the students who bring the joy into teaching." As a professional astronomer, Albers did observational work on Galactic structure in the southern Milky Way, and on the structure of the Magellanic Clouds. In retirement, Albers published Maria Mitchell - A Life in Journals and Letters, the firsthand account of America's first woman astronomer. Albers's research was on photographic near-infrared spectroscopy of red giant stars in the southern Milky Way, some proper motion studies, and on the structure of the Magellanic Clouds. A series of seven NSF grants supported his six trips to Chile to make spectroscopic observations, as well as his sabbatical collaborations at Minnesota, Leiden, and the Royal Observatory in Edinburgh. Henry Albers arrived at Vassar in 1958, to find an astronomy program that had been recently absorbed by the physics department, and that was suffering neglect after the retirement of Maud Makemson. For the next 31 years, with incredible energy -- he sometimes taught seven courses a year -- he built the astronomy program into one double in size (from one to two tenure lines), whose th century facilities have been replaced with a st century observatory. For a remarkable stretch of 20-some-years, Albers and physicist Bob Stearns, with considerable grace, alternated chairmanship of the joint department of physics and astronomy. Henry Albers was a devoted citizen of Vassar College and an enthusiastic participant in the process of faculty governance at that institution. He would have been the first to concede that his enthusiasm was sometimes excessive, and that his contributions at faculty meetings occasionally failed to move the

    We report an 8-year-old girl who manifested Vogt-Koyanagi-Harada (VKH) disease. At the first visit, conjunctival hyperemia, inflammation in the anterior chamber, serous retinal detachment, and papillitis were observed in both eyes. Fluorescein angiography (FA) revealed bilateral subretinal fluid and papillitis. Ocular computed tomography (OCT) showed subretinal fluid and choroidal hypertrophy underneath macula in both eyes. Cerebrospinal fluid examination indicated aseptic meningitis. Systemic data did not suggest the other systemic diseases. Therefore, she was diagnosed with incomplete VKH disease. After corticosteroid pulse therapy, oral prednisolone was administered for seven months. Eighteen days after the induction of the treatments, inflammation in the anterior chamber and serous retinal detachment of both eyes disappeared completely. For seven months after the induction of the treatments, she had no relapses of any symptoms. Cerebrospinal fluid examination and FA for children are difficult to conduct, since it is difficult to get informed consent of these examinations from their parents. However, those thorough examinations enable us to make a swift and definitive diagnosis of VKH disease, thus assuring good visual prognosis. We have to bear in mind that juvenile VKH disease is very rare, yet when it occurs, ophthalmologic examinations help us diagnose and treat it. PMID:27110416

    Vogt-Koyanagi-Harada disease (VKHD) is a multisystemic disorder characterized by granulomatous panuveitis variably combined with T cell-mediated neurologic and cutaneous manifestations. Early and aggressive treatment with systemic corticosteroids is the mainstay of treatment for VKHD. Additional use of immunosuppressants, intravenous immunoglobulins, and tumor necrosis factor-alpha inhibitors can help the most severely affected patients and work as corticosteroid-sparing agents. We report the case of a young woman with relapsing and multiresistant VKHD who demonstrated a stable remission of both uveitis and high-frequency hearing loss following rituximab intravenous administration (1 g. twice, 2 weeks apart, and 6 months later). A complete clinical response was observed 1 month since the first infusion, and no ocular relapses were recorded during the following year; in addition, audiometry showed a high-frequency hearing recovery in the right ear. Further observational studies are required to define the role of CD20 inhibition in the management of VKHD.

    Heinzmann, Gerhard; Villani, Cédric

    2014-08-01

    The year 2012 marked the centenary of the death of Henri Poincaré (Nancy, 1854-Paris, 1912), and through the agency of the Henri-Poincaré Institute in Paris, the Henri-Poincaré Archives in Nancy and The London Mathematical Society, brought with it several exhibitions and meetings commemorating one of the greatest minds in contemporary times. Often referred to as the last polymath, Poincaré embraced multiple branches of mathematics, theoretical physics and celestial mechanics, and made significant contributions to philosophy of science (Heinzmann & Stump, Henri Poincaré, 2013). He wrote 25 textbooks and monographs, 500-plus articles, and was deeply involved in the organization and administration of science at both the national and international levels.1

  15. Fighting desires: Henry Miller's Queer Tropic.

    PubMed

    Hardin, Michael

    2002-01-01

    "Fighting Desires: Henry Miller's Queer Tropic" is an investigation of Tropic of Cancer that investigates the deeply repressed homoerotic desire that periodically surfaces. This reading is dependent upon an interpretation of Eve Sedgwick that proposes male sexuality as a continuum. By looking at the nature of the male-male relationships, as well as the lack of emotion and presence in the male-female relationships, I will show that the most intimate relationships are between men, and that these relationships are expressed through the telling of stories about (heterosexual) sex; this is the function of women within the novel: one has sex with a woman, not for the pleasure that the act brings, but for the pleasure that the recounting of the story to other men brings. Furthermore, I will look at Miller's use of puns within the novel and how they also contribute to a homoerotic reading. None of this is to argue that Miller was not homophobic and sexist--Miller very clearly was--the purpose of this essay is to show the complex nature of sexuality, even within a protagonist who asserts a very defined heterosexuality.

    1997-01-01

    James Paget Henry really began his productive research career at the outset of the second world war. His studies of acceleration and the anoxia of high altitude were supported by the development of then new techniques of measuring and recording critical physiologic parameters such as vascular pressures, respiratory functions and haemoglobin saturation. His inquisitive mind made productive use of the instruments that had to be made by skilled instrument makers working in university shops. Much of this instrumentation has now found its way into the clinical arena where it is now the main armamentarium of cardiac diagnostic and respiratory function laboratories. His work in the space program preceeded that of the Russians but did not get recognition until Sputnik awakened the world to the possibilities of space flight. His development of the concept of a cardiovascular basis for fluid volume control and the supportive investigative work undertaken constitute a milestone in the annals of experimental physiology. The chimpanzees used in Project Mercury were found to be hypertensive which was related to the method of capture used by the commercial suppliers. This lead Jim to study the effect of early experience on resting blood pressure, an effort that soon developed into provocative studies of the biological basis of the stress response.

  17. Applicability of Henry's Law to helium solubility in olivine

    Applicability of Henry's Law to helium solubility in olivine We have experimentally determined helium solubility in San Carlos olivine across a range of helium partial pressures (PHe) with the goal of quantifying how noble gases behave during partial melting of peridotite. Helium solubility in olivine correlates linearly with PHe between 55 and 1680 bar. This linear relationship suggests Henry's Law is applicable to helium dissolution into olivine up to 1680 bar PHe, providing a basis for extrapolation of solubility relationships determined at high PHe to natural systems. This is the first demonstration of Henry's Law for helium dissolution into olivine. Averaging all the data of the PHe series yields a Henry's coefficient of 3.8(×3.1)×10-12 mol g-1 bar-1. However, the population of Henry's coefficients shows a positive skew (skewness = 1.17), i.e. the data are skewed to higher values. This skew is reflected in the large standard deviation of the population of Henry's coefficients. Averaging the median values from each experiment yields a lower Henry's coefficient and standard deviation: 3.2(× 2.3)×10-12 mol g-1 bar-1. Combining the presently determined helium Henry's coefficient for olivine with previous determinations of helium Henry's coefficients for basaltic melts (e.g. 1) yields a partition coefficient of ~10-4. This value is similar to previous determinations obtained at higher PHe (2). The applicability of Henry's Law here suggests helium is incorporated onto relatively abundant sites within olivine that are not saturated by 1680 bar PHe or ~5×10-9 mol g-1. Large radius vacancies, i.e. oxygen vacancies, are energetically favorable sites for noble gas dissolution (3). However, oxygen vacancies are not abundant enough in San Carlos olivine to account for this solubility (e.g. 4), suggesting the 3x10-12 mol g-1 bar-1 Henry's coefficient is associated with interstitial dissolution of helium. Helium was dissolved into olivine using an externally heated

    1997-04-01

    When Joseph Henry accepted the postion of secretary of the Smithsonian in 1846, his career changed radically. Although he never ceased thinking of himself as a research scientist and educator, thereafter his chief roles were those of science administrator and advisor to both the executive and legislative branches of the federal government for both science and technology. His effectiveness as an advocate became more important than his skill as an experimental physicist. Even when he entered the laboratory, his role had changed. No longer was he concerned with basic research. As a member of various government boards and committees, Henry spent the last three decades of his life concerned with the application of fundamental knowledge for the improvement of the human condition. This paper will discuss Henry's service on behalf of his country.

  19. KIR and HLA Genotypes Implicated in Reduced Killer Lymphocytes Immunity Are Associated with Vogt-Koyanagi-Harada Disease

    Cytotoxic T lymphocytes (CTL) and natural killer (NK) cells are killer lymphocytes that provide defense against viral infections and tumor transformation. Analogous to that of CTL, interactions of killer-cell immunoglobulin-like receptors (KIR) with specific human leukocyte antigen (HLA) class I ligands calibrate NK cell education and response. Gene families encoding KIRs and HLA ligands are located on different chromosomes, and feature variation in the number and type of genes. The independent segregation of KIR and HLA genes results in variable KIR-HLA interactions in individuals, which may impact disease susceptibility. We tested whether KIR-HLA combinations are associated with Vogt-Koyanagi-Harada (VKH) disease, a bilateral granulomatous panuveitis that has strong association with HLA-DR4. We present a case control study of 196 VKH patients and 209 controls from a highly homogeneous native population of Japan. KIR and HLA class I genes were typed using oligonucleotide hybridization method and analyzed using two-tailed Fisher’s exact probabilities. The incidence of Bx-KIR genotypes was decreased in VKH patients (odds ratio [OR] 0.58, P = 0.007), due primarily to a decrease in centromeric B-KIR motif and its associated KIRs 2DS2, 2DL2, 2DS3, and 2DL5B. HLA-B22, implicated in poor immune response, was increased in VKH (OR = 4.25, P = 0.0001). HLA-Bw4, the ligand for KIR3DL1, was decreased in VKH (OR = 0.59, P = 0.01). The KIR-HLA combinations 2DL2+C1/C2 and 3DL1+Bw4, which function in NK education, were also decreased in VKH (OR = 0.49, P = 0.012; OR = 0.59, P = 0.013). Genotypes missing these two inhibitory KIR-HLA combinations in addition to missing activating KIRs 2DS2 and 2DS3 were more common in VKH (OR = 1.90, P = 0.002). These results suggest that synergistic hyporesponsiveness of NK cells (due to poor NK education along with missing of activating KIRs) and CTL (due to HLA-B22 restriction) fail to mount an effective immune response against viral

    Abstract Using spectral-domain optical coherence tomography (OCT) to observe the morphology and epithelial thickness (ET) of the palisades of Vogt (POV), and to evaluate the role of age and region on these structures. One hundred twelve eyes of 112 healthy subjects were enrolled and divided into 4 groups: A (0–19), B (20–39), C (40–59), and D (≥60 years old). RTvue-100 OCT was applied on the cornea and the limbus. The morphology of the subepithelial stroma underneath the epithelium of POV was classified into typical and atypical types. Maximum ET of POV was measured manually from OCT images. The positive rate of typical POV in superior, nasal, temporal, and inferior limbus was: Group A: 100%, 69.2%, 65.4%, 100%; Group B: 100%, 73.5%, 61.8%, 94.1%; Group C: 95.8%, 41.7%, 37.5%, 83.3%; Group D: 67.9%, 0%, 3.6%, 25%, showing a significant decreasing tendency with age. The maximum ET of POV in superior, nasal, temporal, and inferior limbus was: Group A: 103.5 ± 10.1 um, 89.2 ± 9.7 um, 87.9 ± 13.6 um, 104.7 ± 14.1 um; Group B: 111.4 ± 15.8 um, 85.3 ± 9.9 um, 88.2 ± 8.6 um, 112.6 ± 19.7 um; Group C: 116.4 ± 16.4 um, 82.8 ± 11.6 um, 87.0 ± 11.6 um, 120.0 ± 25.6 um; Group D: 96.3 ± 17.9 um, 73.8 ± 15.9 um, 79.2 ± 16.7 um, 87.4 ± 18.5 um. Age-dependent change was observed. In general, the maximum ET of POV in superior/inferior quadrants was thicker than the other 2 quadrants. Spectral-domain OCT is a useful tool to observe the limbal microstructure and provide invaluable information. Aging and anatomic regions had significant effects on the microstructure of these areas.

  2. The Henry semianalytical solution for saltwater intrusion with reduced dispersion

    NASA Astrophysics Data System (ADS)

    2012-06-01

    The Henry semianalytical solution for salt water intrusion is widely used for benchmarking density dependent flow codes. The method consists of replacing the stream function and the concentration by a double set of Fourier series. These series are truncated at a given order and the remaining coefficients are calculated by solving a highly nonlinear system of algebraic equations. The solution of this system is often subject to substantial numerical difficulties. Previous works succeeded to provide semianalytical solutions only for saltwater intrusion problems with unrealistic large amount of dispersion. In this work, different truncations for the Fourier series are tested and the Levenberg-Marquardt algorithm, which has a quadratic rate of convergence, is applied to calculate their coefficients. The obtained results provide semianalytical solutions for the Henry problem in the case of reduced dispersion coefficients and for two freshwater recharge values: the initial value suggested by Henry (1964) and the reduced one suggested by Simpson and Clement (2004). The developed semianalytical solutions are compared against numerical results obtained by using the method of lines and advanced spatial discretization schemes. The obtained semianalytical solutions improve considerably the worthiness of the Henry problem and therefore, they are more suitable for testing density dependent flow codes.

    1981-01-01

    A study of the circulation near Cape Henry, Virginia, was made using surface and seabed drifters and radar tracked surface buoys coupled to subsurface drag plates. Drifter releases were conducted on a line normal to the beach just south of Cape Henry. Surface drifter recoveries were few; wind effects were strongly noted. Seabed drifter recoveries all exhibited onshore motion into Chesapeake Bay. Strong winds also affected seabed recoveries, tending to move them farther before recovery. Buoy trajectories in the vicinity of Cape Henry appeared to be of an irrotational nature, showing a clockwise rotary tide motion. Nearest the cape, the buoy motion elongated to almost parallel depth contours around the cape. Buoy motion under the action of strong winds showed that currents to at least the depth of the drag plates substantially are altered from those of low wind conditions near the Bay mouth. Only partial evidence could be found to support the presence of a clockwise nontidal eddy at Virginia Beach, south of Cape Henry.

    NASA Astrophysics Data System (ADS)

    Malville, J.

    2011-12-01

    Roy Henry Garstang 84 passed away on November 1, 2009 in Boulder Colorado. He was born in Southport, England in September of 1925 to Percy Brocklehurst and Eunice (Gledhill) Garstang. He won a scholarship to Caius College in Cambridge University. Because it was wartime, he could spend only two years at his studies. However, he managed to complete three years of required work during that time, and then spent 1945-46 as a Junior Scientific Officer at the Royal Aircraft Establishment at Farnborough. He received his BA in 1946 from Cambridge, his MA in 1950, and his PhD in Mathematics in 1954, with a thesis: "Atomic Transitions in Astrophysics," working under D. R. Hartree. He also received a ScD from Cambridge in Physics and Chemistry in 1983. He married Ann in August 1959. She and two daughters, Jennifer and Susan, survive him. While still pursuing his PhD, Roy Garstang served as a Research Associate at the Yerkes Observatory, from 1951-1952, working under Subrahmanyan Chandrasekhar. During that time he continued with his own calculations of atomic structure and transition probabilities, although these were not part of Chandra's research interests. After earning his PhD, he went to teach at the University of London, where he also served as the Assistant Director of the University of London Observatory (1959-1964). He was editor of "The Observatory" Magazine form 1953-1960. The continuing theme of this research was to help meet the needs of astrophysicists for atomic data. In 1964, he left England for the United States, where he joined the faculty at the University of Colorado, Boulder, where he would remain for the rest of his professional career. It was entirely fitting, considering his interest in performing calculations of interest to astrophysicists, that soon after arriving in Boulder he was appointed Chairman of JILA - Joint Institute for Laboratory Astrophysics (1966-1967). He was Director of the Division of Physics and AstroGeophysics (1979-80), acting

  20. Geology and geography of the Henry Mountains region, Utah

    Hunt, Charles B.; Averitt, Paul; Miller, Ralph L.

    1953-01-01

    The Henry Mountains region in southeastern Utah is one of the classic areas in geology because of the study made there by Grove Karl Gilbert in 1875 and 1876. His report on the geology of the mountains was the first to recognize that intrusive bodies may deform their host rocks and the first to show clearly the significance of the evenly eroded plains, now known as pediments, at the foot of desert mountains.The Henry Mountains with the surrounding structural basin is a rugged, dry, and sparsely settled region, a part of the Colorado Plateaus province. The natural obstacles of the region-the aridity and ruggedness-have kept it primitive. It has not been penetrated by modern methods of transportation and thus it persists as a roadless frontier. Even the Indians seem to have made little use of the region; explorers did not enter it until 1869 and settlements were not started until the eighties.

    Sarcophilia, a neologism for an attachment to human remains, is set in a review of the history of the disposal of the dead. The ancient practice of cremation was relaunched late in the 19th century by the urological surgeon cum social reformer Sir Henry Thompson. He was stimulated by Edwin Chadwick and Charles Dickens, and by Charles Darwin's observations on the earthworm. Sarcophilia is the reason for the controversial Human Tissue Act of 2004.

    The Henry's law constants of seven aldehydes have been determined as a function of temperature by bubble-column and by head-space techniques. The compounds were chosen for their potential importance in the polluted troposphere and to allow structure-reactivity patterns to be investigated. The results (at 25/degree/C) are as follows (in units of M atm/sup /minus/1/): chloral, 3.44 /times/ 10/sup 5/; glyoxal, greater than or equal to3 /times/ 10/sup 5/; methylglyoxal, 3.71 /times/ 10/sup 3/; formaldehyde, 2.97 /times/ 10/sup 3/; benzaldehyde, 3.74 /times/ 10/sup 1/; hydroxyacetaldehyde, 4.14 /times/ 10/sup 4/; acetaldehyde, 1.14 /times/ 10/sup 1/. A plot of Taft's parameter, ..sigma..sigma*, vs log H* (the apparent Henry's law constant) gives a straight line with a slope of 1.72. H* for formaldehyde is anomalously high, as expected, but the extremely high value for hydroxyacetaldehyde was unexpected and may indicate that ..cap alpha..-hydroxy-substituted aldehydes could have an usually high affinity for the aqueous phase. The intrinsic Henry's law constants, H, corrected for hydration, do not show a clear structure-reactivity pattern for this series of aldehydes.

  6. BOOK REVIEW: Joseph Henry: The Rise of an American Scientist

    NASA Astrophysics Data System (ADS)

    Crawford, Elspeth

    1998-09-01

    Albert Moyer has clearly done his research into the events of Joseph Henry's life. The personal, professional, sociological and scientific aspects have been meticulously detailed throughout and the ordering, as in the chapter headings, is chronological, so that there is some element of each of these aspects in each chapter. This is unfortunately both the strength and the weakness of the biography, as the detail seemed to me to be the most remarkable characteristic of the writing. But, the bigger stories, or the themes, which might have been possible, seemed to get lost. Hence, I found this a book for those who are seriously interested in Joseph Henry; but for those whose interest might be more general, say having an interest in nineteenth century growth of scientific institutions, or wanting to understand the conceptual development of electromagnetism, there seemed to be too much which came from the Henry point of view, rather than locating Henry within his time and context. This is a remark about style, rather than omission of content, as the myriad of details in each paragraph certainly inform the reader about the context. For instance, some sociology of the USA in the nineteenth century could be inferred, say showing how a young man from a modest background might make his way into a professional life, but the information is so particularly a description of Henry's experience that one has to rely on prior knowledge or make assumptions in order to create a sociological perspective. That is, I now know, what happened to Henry, but I do not know if his case was in any sense typical or atypical. Similarly there is information about education in general at that time, and scientific education, research and its publication, as it applied to Henry. The relationships between science in the USA and in Europe have a place, and there is quite a bit of information about the institutions in which Henry worked, particularly Albany Academy, Princeton and the Smithsonian.

    PubMed

    Lafont, O

    2008-01-01

    Born in Paris on September 28, 1852, son of an eastern railways' employee and of a dressmaker, Henri Moissan's secondary schooling in Meaux did not allow him to get access to the sesame diploma "baccalauréat" (GCE). In 1869, he did obtain a special certificate of secondary schooling so that he could become an apprentice in watch making. That could have been the end of the story, but dreadful event for France appeared to have beneficial effects for Moissan. Under the threat of the Prussian army, Moissan's family took refuge near Paris. This gave the young Henri the opportunity to register as a student for the second-class pharmacy diploma, which did not need, at the time, the GCE. Moissan became then a trainee in pharmacy in 1871. Meanwhile, he followed the special schooling of "Ecole de chimie" founded by E. Frémy, and then joined the laboratory of Dehérain at the Museum, where he worked in plant physiology. He finally obtained the famous "baccalauréat" (GCE) and could register as a student in first-class pharmacy. He became a pharmacist as well as a doctor in sciences. In 1883, Moissan was named professor at the school of pharmacy in Paris. In 1886, he isolated fluorine by electrolysis of fluorhydric acid, in the presence of potassium fluoride, at a low temperature. He then studied diamond synthesis and gave a start to high temperature chemistry, designing his famous furnace. These findings and many others allowed Moissan to rise to membership in many learned academies around the world. Crowning achievement, Moissan won the Nobel Prize in 1906. A man of culture, collector of autographs and paintings, he died in 1907. Nothing of that would have been possible if there had not been a second-class pharmacist diploma. The history of Henri Moissan is one of a rise from apprenticeship to the Nobel Prize.

  10. Henry Cavendish, Johann von Soldner, and the deflection of light

    The gravitational deflection of light based on Newtonian theory and the corpuscular model of light was calculated, but never published, around 1784 by Henry Cavendish, almost 20 years earlier than the first published calculation by Johann Georg von Soldner. The two results are slightly different because, while Cavendish treated a light ray emitted from infinity, von Soldner treated a light ray emitted from the surface of the gravitating body. At the first order of approximation, they agree with each other; both are one-half the value predicted by general relativity and confirmed by experiment.

    The French psychiatrist Henri Ey developed his organo-dynamic theory of the mind function and consciousness 50 years ago incorporating Hughling Jackson's thinking, along with psychiatric and philosophical theorizations by Janet and Bergson. This model has not received the attention it deserved, but recent advances in neuroscience rekindled interest for Ey's theory. By overcoming the Cartesian mind-body dualism and treating the mind-body unit as an inseparable whole, this model opens the way for the integrated treatment of mental disorders. Ey's conceptualization of consciousness as being simultaneously both synchronous and diachronic anticipates current theories of consciousness (Damasio, Edelman, Mesulam).

    Vogt-Koyanagi-Harada (VKH) disease and central serous chorioretinopathy (CSC) develop serous retinal detachment; however, the treatment of each disease is totally different. Steroids treat VKH but worsen CSC; therefore, it is important to distinguish these diseases. Here, we report a case with CSC which was diagnosed by en face optical coherence tomography (OCT) imaging during the course of VKH disease. A 50-year-old man was referred with blurring of vision in his right eye. Fundus examination showed bilateral optic disc swelling and macular fluid in the right eye. OCT showed thick choroid, and en face OCT images depicted blurry choroid without clear delineation of choroidal vessels. Combined with angiography findings, this patient was diagnosed with VKH disease and treated with steroids. Promptly, fundus abnormalities resolved with the reduction of the choroidal thickness and the choroidal vessels became visible on the en face images. During the tapering of the steroid, serous macular detachment in the right eye recurred several times. Steroid treatment was effective at first; however, at the fourth appearance of submacular fluid, the patient did not respond. At that time, the choroidal vessels on the en face OCT images were clear, which significantly differed from the images at the time of recurrence of VKH. Angiography also suggested CSC-like leakage. The tapering of the steroids was effective in resolving the fluid. Secondary CSC may develop in the eye with VKH after steroid treatment. En face OCT observation of the choroid may be helpful to distinguish each condition.

    Vogt-Koyanagi-Harada (VKH) syndrome is a systemic autoimmune disease. CD4+ T cells have been shown to be involved in autoimmune diseases including VKH syndrome. To screen aberrantly expressed membrane proteins in CD4+ T cell from patients with active VKH syndrome, blood samples were taken from five patients with active VKH syndrome and five healthy individuals. A label-free quantitative proteomic strategy was used to identify the differently expressed proteins between the two groups. The results revealed that the expression of 102 peptides was significantly altered (p<0.05) between two groups and matched amino acid sequences of proteins deposited in the international protein index (ipi.HUMAN.v3.36.fasta). The identified peptides corresponded to 64 proteins, in which 30 showed more than a 1.5-fold difference between the two groups. The decreased expression of CD18 and AKNA transcription factor (AKNA), both being three-fold lower than controls in expression identified by the label-free method, was further confirmed in an additional group of five active VKH patients and six normal individuals using the Western blot technique. A significantly decreased expression of CD18 and AKNA suggests a role for both proteins in the pathogenesis of this syndrome. PMID:21297967

    The purpose of this report is to evaluate the efficacy and safety of combined intravitreal injection of bevacizumab and intravitreal triamcinolone acetonide (IVTA) for recurrent inflammatory choroidal neovascular membrane (CNVM). It was a prospective interventional study of a young female, who was a known case of Vogt-Koyanagi-Harada syndrome. She presented with an inflammatory choroidal neovascualar membrane and signs of panuveitis in the right eye. She underwent a complete ophthalmic examination. She was given intravitreal injection of bevacizumab and IVTA at different sites. There was complete regression of CNVM and ocular inflammation within a week. After six months, she had recurrence of CNVM in the same eye, which was treated similarly. There was a complete resolution of CNVM and ocular inflammation after the combination therapy and systemic steroids, until one year of follow-up. No serious systemic or ocular adverse events were noted. Combination therapy appears to be an effective and safe method in the management of recurrent inflammatory CNVM. PMID:23202396

    The Henry Mountains have been visited only by the explorer. Previous to 1869 they were not placed upon any map, nor was mention made of them in any of the published accounts of exploration or survey in the Rocky Mountain region. In that year Professor Powell while descending the Colorado River in boats passed near their foot, and gave to them the name which they bear in honor of Prof. Joseph Henry, the distinguished physicist. In 1872 Prof. A. H. Thompson, engaged in the continuance of the survey of the river, led a party across the mountains by the Penellen Pass, and climbed some of the highest peaks. Frontiersmen in search of farming and grazing lands or of the precious metals have since that time paid several visits to the mountains; but no survey was made of them until the years 1875 and 1876, when Mr. Walter H. Graves and the writer visited them for that purpose. They are situated in Southern Utah, and are crossed by the meridian of 110° 45' and the thirty-eighth parallel. They stand upon the right bank of the Colorado River of the West, and between its tributaries, the Dirty Devil and the Escalante.

    This paper provides a detailed thermodynamic analysis of gas/vapour adsorption in zeolites at low pressures. At these conditions, we show first that Henry's isotherm can be conveniently rewritten using the thermodynamic isotherm model developed in a previous study [J. Llorens, M. Pera-Titus, Description of gas adsorption on microporous materials: evaluation of energy heterogeneity, J. Colloid Interface Sci. 331, 2009, 302-311], linking the integral free energy of adsorption relative to saturation, Ψ/ RT, expressed as a Kiselev integral, with the variable Z = 1/-ln( Π), being Π the relative pressure. Relevant information about sorbate confinement effects in zeolites can be inferred using strong sorbates under Henry's adsorption regime using the thermodynamic formulation provided here. The confining level of zeolites can be characterized by a parameter ( m1), whose value depends on the zeolite framework, but remains essentially unchanged with the sorbate probe molecule and temperature. We illustrate the application of these concepts using a collection of MFI and MTW-type zeolites as model systems.

While Cavendish is rightfully considered a brilliant experimenter by many historians, he is often credited (in both popular and historical literature) as the scientist who first accurately weighed the Earth and determined the universal constant of gravitation, G. While the universal constant of gravitation and the mass (or weight) of the Earth can indeed be calculated from the density of the Earth, this was neither Cavendish's result nor his intent in writing "Experiments to Determine the Density of the Earth." Rather, Cavendish's interest lies in solving an eighteenth-century dispute: what is the mean density of the Earth?

    Larix olgensis Henry is an important coniferous species found in plantation forests in northeastern China, but it is vulnerable to pathogens. Nitric oxide (NO) is an important molecule involved in plant resistance to pathogens. To study the regulatory role of NO at the transcriptional level, we characterized the transcriptomic response of L. olgensis seedlings to sodium nitroprusside (SNP, NO donor) using Illumina sequencing and de novo transcriptome assembly. A significant number of putative metabolic pathways and functions associated with the unique sequences were identified. Genes related to plant pathogen infection (FLS2, WRKY33, MAPKKK, and PR1) were upregulated with SNP treatment. This report describes the potential contribution of NO to disease resistance in L. olgensis as induced by biotic stress. Our results provide a substantial contribution to the genomic and transcriptomic resources for L. olgensis, as well as expanding our understanding of the involvement of NO in defense responses at the transcriptional level.

    Emily Dickinson is one of America's premier poets of the 19th century. Henry Willard Williams, MD, was one of the very first physicians to limit his practice to ophthalmology and was the established leader in his field in Boston, Massachusetts. They met during the time of the Civil War, when Emily consulted him about her ophthalmic disorder. No records of the diagnosis survive. Photophobia, aching eyes, and a restriction in her ability to work up close were her main symptoms. Iritis, exotropia, or psychiatric problems are the most frequent diagnoses offered to explain her difficulties. Rather than attempt a definitive conclusion, this article will offer an additional possibility that Dr Williams likely considered (ie, hysterical hyperaesthesia of the retina). This was a common diagnosis at that time, although it has currently faded from use.

    This compendium contains papers presented at the W. E. Henry Symposium, The Importance of Magnetism in Physics and Material Science. The one-day symposium was conducted to recognize the achievements of Dr. Warren Elliot Henry as educator, scientist, and inventor in a career spanning almost 70 years. Dr. Henry, who is 88 years old, attended the symposium. Nobel Laureate, Dr. Glenn Seaborg, a friend and colleague for over 40 years, attended the event and shared his personal reminiscences. Dr. Seaborg is Associate Director-At-Large at the Lawrence Berkeley National Laboratory. The Compendium begins with three papers which demonstrate the ongoing importance of magnetism in physics and material science. Other contributions cover the highlights of Dr. Henry`s career as a researcher, educator, and inventor. Colleagues and former students share insights on the impact of Dr. Henry`s research in the field of magnetism, low temperature physics, and solid state physics; his influence on students as an educator; and his character, intellect and ingenuity, and passion for learning and teaching. They share a glimpse of the environment and times that molded him as a man, and the circumstances under which he made his great achievements despite the many challenges he faced.

    The pro-inflammatory cytokines play a critical role in the initiation and propagation of ocular autoimmune diseases. Regulation of these cytokines is generally mediated by the immunoregulatory cytokine such as IL-10 or TGF-beta. In this study, we investigated the immunoregulatory cytokine profile and frequency of natural regulatory T cells (nTregs) in patients with Vogt-Koyanagi-Harada (VKH). We obtained the peripheral blood mononuclear cells (PBMC) from patients with VKH and healthy controls. The cytokine profile from supernatants of PBMC cultured with or without phytohaemagglutinin (PHA) was measured by ELISA, the percentage of CD4(+) Foxp3(+) and CD25(high)Foxp3(+) T regulatory cells were analysed by flow cytometry, and the transcriptional level of Foxp3 expression was analysed by real-time quantitative PCR. The immunoregulatory cytokines, TGF-beta and IL-10, increased in patients with VKH in the inactive stage of the disease. We observed no significant difference in the CD4(+) Foxp3(+) and CD25(high)Foxp3(+) T cells as well as no reduction in FOXP3 mRNA expression in the patients with VKH when compared to healthy controls. We showed in our work, an increase in IFN-gamma secretion by PBMC of patients with VKH in the active stage of the disease when compared to healthy controls and patients in the inactive stage. Our data suggest that IL-10 and TGF-beta cytokines, rather than nTregs are associated with the resolution phase of the disease and may have a more relevant role in controlling this disease.

    Purpose To determine if early post-treatment central choroidal thickness (CCT) changes can predict sunset glow fundus (SGF) development in patients with Vogt-Koyanagi-Harada (VKH) disease treated using systemic corticosteroids. Methods This retrospective case series included 39 eyes of 21 treatment-naïve patients with acute VKH disease who could be followed up for more than 12 months after systemic corticosteroid therapy. The eyes were divided into two groups according to whether SGF was present or absent at 12 months (9 eyes of 5 patients versus 30 eyes of 16 patients, respectively). Using enhanced depth imaging optical coherence tomography, CCT values were measured before treatment, then at 1 week and 1 and 3 months after treatment in both groups and compared between the two groups. Results Development of SGF was found 4–11 months after treatment. Mean post-treatment CCT decreased significantly at all examinations compared with baseline in both groups, along with resolution of serous retinal detachment. One week after treatment, mean CCT was significantly higher in eyes with SGF than in those without (P = 0.024). SGF was present at 12 months in 9 of 22 eyes with CCT values > 410 μm at 1 week after starting treatment, in contrast with none of 17 eyes with CCT ≤ 410 μm at this time (P = 0.003). Conclusions The current study suggested the potential validity of early post-treatment CCT as a feasible index to alert future progression to SGF in patients with VKH disease treated using systemic corticosteroids.

    Biogenically produced reduced sulfur compounds, including dimethylsulfide (DMS, CH{sub 3}SCH{sub 3}), hydrogen sulfide (H{sub 2}S), carbon disulfide (CS{sub 2}), methyl mercaptan (CH{sub 3}SH), and carbonyl sulfide (OCS), are a major source of sulfur in the marine atmosphere. This source is estimated to contribute 25-40% of global sulfur emissions. These species and their oxidation products, dimethyl sulfoxide (DMSO), dimethyl sulfone (DMSO{sub 2}), and methane sulfonic acid (MSA), dominate the production of aerosol and cloud condensation nuclei (CCN) in the clean marine atmosphere. The multiphase chemical processes for these species must be understood in order to study the evolving role of combustion-produced sulfur oxides over the oceans. Using a newly developed bubble column apparatus, a series of aqueous phase uptake studies have been completed for the reduced sulfur species DMS, H{sub 2}S, CS{sub 2}, CH{sub 3}SH, and OCS. Aqueous phase uptake has been studied as a function of temperature (278-298 K), pH (1-14), H{sub 2}O{sub 2} concentration (0-1 M), NaCl concentration (0-5 M), and (NH{sub 4}){sub 2}SO{sub 4} concentration (0-4 M). The Henry`s law coefficients for CH{sub 3}SH and CS{sub 2} were determined for the first time, as were the Setchenow coefficients for all the species studied. 33 refs., 8 figs., 2 tabs.

    Given the significance of carbohydrates in life, medicine, and industry, the development of simple and efficient de novo methods to synthesize carbohydrates are highly desirable. Organocatalytic asymmetric assembly reactions are powerful tools to rapidly construct molecules with stereochemical complexity from simple precursors. Here, we present a simple and robust methodology for the asymmetric synthesis of pyranose derivatives with talo- and manno- configurations from simple achiral precursors through organocatalytic asymmetric intermolecular Michael–Henry reaction sequences. In this process, (tert-butyldimethylsilyloxy)acetaldehyde 1 was successfully utilized in two ways: as a donor in a highly selective anti-Michael reaction and as an acceptor in a consecutive Henry reaction. Varied nitroolefins served as Michael acceptors and varied aldehydes substituted for 1 as Henry acceptors providing for the construction of a wide range of carbohydrates with up to 5 stereocenters. In these reactions, a catalyst-controlled Michael reaction followed by a substrate-controlled Henry reaction provided 3,4-dideoxytalose derivatives 6 in a highly stereoselective manner. The Henry reaction was affected by addition of a simple base such as triethylamine: A complex chiral base was not necessary. 3,4-Dideoxymannose derivatives 7 were produced by simply changing the base from triethylamine to 1,8-diazabicyclo[5.4.0]undec-7-ene. Extension of this methodology to a syn-Michael initiated sequence was also successful. A mechanistic discussion is provided to explain the unusual substrate-induced stereoselectivity of the Henry reaction. PMID:20639468

  17. Henry's voices: the representation of auditory verbal hallucinations in an autobiographical narrative.

    2015-06-01

    The book Henry's Demons (2011) recounts the events surrounding Henry Cockburn's diagnosis of schizophrenia from the alternating perspectives of Henry himself and his father Patrick. In this paper, we present a detailed linguistic analysis of Henry's first-person accounts of experiences that could be described as auditory verbal hallucinations. We first provide a typology of Henry's voices, taking into account who or what is presented as speaking, what kinds of utterances they produce and any salient stylistic features of these utterances. We then discuss the linguistically distinctive ways in which Henry represents these voices in his narrative. We focus on the use of Direct Speech as opposed to other forms of speech presentation, the use of the sensory verbs hear and feel and the use of 'non-factive' expressions such as I thought and as if. We show how different linguistic representations may suggest phenomenological differences between the experience of hallucinatory voices and the perception of voices that other people can also hear. We, therefore, propose that linguistic analysis is ideally placed to provide in-depth accounts of the phenomenology of voice hearing and point out the implications of this approach for clinical practice and mental healthcare.

  18. Effects of surfactants and salt on Henry's constant of n-hexane.

    n-Hexane biological removal is intrinsically limited by its hydrophobic nature and low bioavailability. The addition of surfactants could enhance the transport of volatile organic compounds (VOCs) and change the gas-liquid equilibrium of VOCs. In this paper, the effects of four surfactants, sodium dodecyl sulfate (SDS), cetyltrimethylammonium bromide (CTAB), tert-octylphenoxypoly-ethoxyethanol (Triton X-100), polyoxyethylene (20) sorbitan monooleate (Tween 80), and sodium nitrate on apparent Henry's constant of n-hexane in surfactant solutions were investigated. The apparent Henry's constants were significantly reduced when surfactants concentrations exceeded their critical micelle concentrations (cmc's). On a cmc basis, the anionic surfactant SDS was found to have the greatest effect on the apparent Henry's constant with CTAB succeeding, then followed by Triton X-100 and Tween 80. However, the apparent Henry's constant of n-hexane decreased even more rapidly when Triton X-100, a nonionic surfactant, was added than when the ionic surfactant of SDS or CTAB was applied under identical mass concentration and other conditions. These results suggest that Triton X-100 have the biggest solubilization of n-hexane among the four surfactants. Sodium nitrate slightly decreased the apparent Henry's constant of n-hexane in surfactant solutions, and could be considered as a cosolvent in the surfactant-(n-hexane) solution. In addition, the relationship between apparent Henry's constant and surfactant concentration was further developed.

  19. Enzyme-Catalyzed Henry Reaction in Choline Chloride-Based Deep Eutectic Solvents.

    2016-01-01

    The enzyme-catalyzed Henry reaction was realized using deep eutectic solvents (DESs) as a reaction medium. The lipase from Aspergillus niger (lipase AS) showed excellent catalytic activity toward the substrates aromatic aldehydes and nitromethane in choline chloride:glycerol at a molar ratio of 1:2. Addition of 30 vol% water to DES further improved the lipase activity and inhibited DES-catalyzed transformation. A final yield of 92.2% for the lipase AS-catalyzed Henry reaction was achieved under optimized reaction conditions in only 4 h. In addition, the lipase AS activity was improved by approximately 3-fold in a DES-water mixture compared with that in pure water, which produced a final yield of only 33.4%. Structural studies with fluorescence spectroscopy showed that the established strong hydrogen bonds between DES and water may be the main driving force that affects the spatial conformation of the enzyme, leading to a change in lipase activity. The methodology was also extended to the aza-Henry reaction, which easily occurred in contrast to that in pure water. The enantioselectivity of both Henry and aza-Henry reactions was not found. However, the results are still remarkable, as we report the first use of DES as a reaction medium in a lipase-catalyzed Henry reaction.

  20. Henri Poincaré and the principle of relativity

    Often considered as the last 'encyclopedist', Henri Poincaré died one hundred years ago. If he was a prominent man in 1900 French Society, his heritage is not so clearly recognised, particularly in France. Among his too often misunderstood works is his contribution to the theory of relativity, mainly because it is almost never presented within Poincaré's general approach to science, including his philosophical writings. Our aim is therefore to provide an historical account of the main steps (experimental as well as theoretical) which led Poincaré to contribute to the theory of relativity. Starting from the optical experiments which led to the inconsistency of the classical (Galilean) composition law for velocities to explain light propagation, we introduce the FitzGerald and Lorentz contraction which was viewed as the 'sole hypothesis' to explain the Michelson and Morley experiment. We then show that Poincaré's contribution starts with a discussion of the principles governing the mechanics and was built step by step up to express in all its generality the principle of relativity. Poincaré thus showed the invariance of the Maxwell equations under the Lorentz transformation. In doing so, he also discovered the right composition law for velocities. Poincaré's approach to philosophy is detailed to help the reader to understand what a theory meant to him.

  1. A citation analysis of Henri Tajfel's work on intergroup relations.

    2009-02-01

    The late Henri Tajfel (1919-1982) is one of the central figures who shaped the development of post-war European social psychology. His contributions range from the establishment of an infrastructure for a European social psychology, and the start of a new intellectual movement within social psychology, to the formulation of a set of concepts addressing intergroup relations that were finally integrated into Social Identity Theory. The present study provides an empirical examination of Tajfel's contribution to intergroup research over the last 30 years via a citation analysis of five journals: the Journal of Personality and Social Psychology, the British Journal of Social Psychology, the European Journal of Social Psychology, the South African Journal of Psychology, and the German Journal of Social Psychology (Zeitschrift für Sozialpsychologie). The results indicate that Tajfel's work on intergroup relations is increasingly cited, especially since the 1990s, and the international recognition of his work is substantial. Three possible reasons for the recognition his work still enjoys are proposed: its potential to generate theoretical and empirical controversies; its explanatory power; and the extent to which his work is used as a referential framework.

    A dynamic system based on the water/air equilibrium at the interface within the length of a microporous tube has been used to determine experimentally the Henry's law constants (HLC) of two pesticides: metolachlor and diazinon. The measurements were conducted over the temperature range 283-301 K. At 293 K, HLCs values are (42.6+/-2.8) x 10(3) (in units of M atm(-1)) for metolachlor and (3.0+/-0.3)x10(3) for diazinon. The obtained data were used to derive the following Arrhenius expressions: HLC=(3.0+/-0.4) x 10(-11) exp((10,200+/-1,000)/T) for metolachlor and (7.2+/-0.5) x 10(-15) exp((11,900+/-700)/T) for diazinon. At a cumulus cloud temperature of 283 K, the fractions of metolachlor and diazinon in the atmospheric aqueous phase are about 57% and 11% respectively. In order to evaluate the impact of a cloud on the atmospheric chemistry of both studied pesticides, we compare also their atmospheric lifetimes under clear sky (tau(gas)), and cloudy conditions (tau(multiphase)). The calculated multiphase lifetimes (in units of hours) are significantly lower than those in gas phase at a cumulus temperature of 283 K (in parentheses): metolachlor, 0.4 (2.9); diazinon, 1.9 (5.0).

  3. Genetic Analysis of the Henry Mountains Bison Herd.

    Wild American plains bison (Bison bison) populations virtually disappeared in the late 1800s, with some remnant animals retained in what would become Yellowstone National Park and on private ranches. Some of these private bison were intentionally crossbred with cattle for commercial purposes. This forced hybridization resulted in both mitochondrial and nuclear introgression of cattle genes into some of the extant bison genome. As the private populations grew, excess animals, along with their history of cattle genetics, provided founders for newly established public bison populations. Of the US public bison herds, only those in Yellowstone and Wind Cave National Parks (YNP and WCNP) appear to be free of detectable levels of cattle introgression. However, a small free-ranging population (~350 animals) exists on public land, along with domestic cattle, in the Henry Mountains (HM) of southern Utah. This isolated bison herd originated from a founder group translocated from YNP in the 1940s. Using genetic samples from 129 individuals, we examined the genetic status of the HM population and found no evidence of mitochondrial or nuclear introgression of cattle genes. This new information confirms it is highly unlikely for free-living bison to crossbreed with cattle, and this disease-free HM bison herd is valuable for the long-term conservation of the species. This bison herd is a subpopulation of the YNP/WCNP/HM metapopulation, within which it can contribute significantly to national efforts to restore the American plains bison to more of its native range.

    In spite of his contribution to psychiatry in 19th century Britain, Henry Maudsley remains a mysterious figure, a man mostly known for his donation to the London County Council for the building of the Maudsley Hospital and for The Maudsley Annual Lecture created in honour of his benevolence. Besides Sir Aubrey Lewis' article in 1951 and Michael Collie's attempt in 1988 to construct a biographical study on Maudsley, there does not seem to be any current endeavour to tell the story of his life, whereas Trevor Turner's contribution to the 2004 Oxford Dictionary of National Biography gives a somewhat scathing but unattributed account of Maudsley's personality. This essay attempts to explore his contributions to the Medico-Psychological Association (MPA), the current Royal College of Psychiatrists, his editorship of the Journal of Mental Health (currently named the British Journal of Psychiatry), his literary contributions and his vision for a psychiatric hospital. This essay is an attempt to demystify his figure and to explore some of the rumours and criticisms surrounding his name and the reasons why so little has been written about him. It is also a venture to unravel his complex personality and his intricate philosophy.

  5. James Henry Marriott: New Zealand's first professional telescope-maker

    James Henry Marriott was born in London in 1799 and trained as an optician and scientific instrument- maker. In 1842 he emigrated to New Zealand and in January 1843 settled in the newly-established town of Wellington. He was New Zealand's first professional telescope-maker, but we have only been able to locate one telescope made by him while in New Zealand, a brass 1-draw marine telescope with a 44-mm objective, which was manufactured in 1844. In 2004 this marine telescope was purchased in Hawaii by the second author of this paper. In this paper we provide biographical information about Marriott, describe his 1844 marine telescope and speculate on its provenance. We conclude that although he may have been New Zealand's first professional telescope-maker Marriot actually made very few telescopes or other scientific instruments. As such, rather than being recognised as a pioneer of telescope-making in New Zealand he should be remembered as the founder of New Zealand theatre.

  6. The Works of Henry Moseley, 1887-1915

    2013-04-01

    In 1913 Henry Moseley, an unknown young English physicist published an article in the Philosophical Magazine under the title of ``The High Frequency Spectra of the Elements.'' The 10-page article was to have far reaching implications in both chemistry and physics and helped to resolve a major conundrum in the periodic table of the elements. The talk will briefly examine the life and work of Moseley who died tragically while fighting in the trenches of World War I in 1915. The build-up to the discovery of atomic number took several different avenues including contributions from Rutherford and Barkla. However the more direct motivation for Moseley's work, as he readily acknowledged, were the articles of an unknown Dutch econometrician Anton Van den Broek who attempted to improve on Mendeleev's periodic table. Moseley began as a student of Rutherford at Manchester and took a keen interest in the development of research using X-rays following the work of Roentgen, von Laue and Bragg. Although Rutherford was at first reluctant to enter this new field he soon yielded to young Moseley's request and sent him to Leeds for brief training with Bragg. On returning to Manchester, Moseley devised an ingenious apparatus in which a set of metal samples could be rotated so as to become the target for a beam of electrons in order to measure the frequencies of the emitted K X-rays. The first set of such experiments used nine successive elements in the periodic table, from titanium to zinc. Moseley's now immense fame rests with the results of this study as well as a subsequent one which extended the study into a further 30 elements, in addition to the use that his method was put to by himself as well as subsequent chemists and physicists.

  7. On the Henry constant and isosteric heat at zero loading in gas phase adsorption.

    2008-08-01

    The Henry constant and the isosteric heat of adsorption at zero loading are commonly used as indicators of the strength of the affinity of an adsorbate for a solid adsorbent. It is assumed that (i) they are observable in practice, (ii) the Van Hoff's plot of the logarithm of the Henry constant versus the inverse of temperature is always linear and the slope is equal to the heat of adsorption, and (iii) the isosteric heat of adsorption at zero loading is either constant or weakly dependent on temperature. We show in this paper that none of these three points is necessarily correct, first because these variables might not be observable since they are outside the range of measurability; second that the linearity of the Van Hoff plot breaks down at very high temperature, and third that the isosteric heat versus loading is a strong function of temperature. We demonstrate these points using Monte Carlo integration and Monte Carlo simulation of adsorption of various gases on a graphite surface. Another issue concerning the Henry constant is related to the way the adsorption excess is defined. The most commonly used equation is the one that assumes that the void volume is the volume extended all the way to a boundary passing through the centres of the outermost solid atoms. With this definition the Henry constant can become negative at high temperatures. Although adsorption at these temperatures may not be practical because of the very low value of the Henry constant, it is more useful to define the Henry constant in such a way that it is always positive at all temperatures. Here we propose the use of the accessible volume; the volume probed by the adsorbate when it is in nonpositive regions of the potential, to calculate the Henry constant.

    Henry Daniel Cogswell (Fig. 1), the second of five children, was born in Tolland, Connecticut on March 3, 1819. His father, George Washington Cogswell, was a general carpenter, architect and builder of moderate circumstances. In 1827, when Henry was eight, his mother died. The following year, Henry's father moved to Orwell, (Oswego County) New York, in hopes of improving his financial condition. Henry was left behind in the care of his paternal grandfather, who died several months later, leaving the 10-year old boy, stranded and forced to rely upon his own resources. (In those times, when families were separated, individual members had limited means of locating one another.)

    SEAWAT is a coupled version of MODFLOW and MT3DMS designed to simulate variable-density ground water flow and solute transport. The most recent version of SEAWAT, called SEAWAT Version 4, includes new capabilities to represent simultaneous multispecies solute and heat transport. To test the new features in SEAWAT, the laboratory experiment of Henry and Hilleke (1972) was simulated. Henry and Hilleke used warm fresh water to recharge a large sand-filled glass tank. A cold salt water boundary was represented on one side. Adjustable heating pads were used to heat the bottom and left sides of the tank. In the laboratory experiment, Henry and Hilleke observed both salt water and fresh water flow systems separated by a narrow transition zone. After minor tuning of several input parameters with a parameter estimation program, results from the SEAWAT simulation show good agreement with the experiment. SEAWAT results suggest that heat loss to the room was more than expected by Henry and Hilleke, and that multiple thermal convection cells are the likely cause of the widened transition zone near the hot end of the tank. Other computer programs with similar capabilities may benefit from benchmark testing with the Henry and Hilleke laboratory experiment.

  11. Annie Jump Cannon: `` Life after The Henry Draper Catalogue.''

    NASA Astrophysics Data System (ADS)

    Welther, B. L.

    1993-05-01

    Seventy-five years ago the first three volumes of The Henry Draper Catalogue were published. The pages printed in 1918 contain the spectral types, revised magnitudes, and updated positions for more than 77,000 stars. For the nine volumes of the catalogue, Cannon classified spectra for 225,300 stars; and in her lifetime, spectra for almost 400,000 stars. This work netted her half a dozen honorary degrees, the Draper Medal of the NAS, and numerous other prizes and honors. In his preface to Volume 1, Edward Pickering noted that it took two years to process the copy for the initial volumes and estimated that it would take two more years to complete the copy for the remaining volumes. But shortly after he wrote the preface for Volume 3 in December 1918, Pickering died. And it proved to take three times as long as he had predicted to complete the publication of all nine volumes of the catalogue by the spring of 1924. Although Cannon had enjoyed much more independence and status than the other women at HCO, she had looked to Pickering for guidance and financial support for her astronomical projects. Without him, she had to develop other resources and also had to represent the Harvard Classification for the first IAU meeting in Rome in 1922. Although she did not attend the meeting, she corresponded with Frederick Seares at Mount Wilson Observatory about various questions that astronomers had raised about classifying spectra. Meanwhile, in 1921 Harlow Shapley was appointed Director of HCO. He oversaw the publication of the final volumes of the HD and encouraged Cannon to extend it for stars in special regions. For the HD Extension, he hired Margaret Walton to assist Cannon. But the cost of labor to determine positions and magnitudes was prohibitive, so for many stars the HDE lists only the BD number and spectral type. Even that format proved too costly in the depression and war years. Consequently, the last volume of the HDE was published as charts after World War II.

  12. Dr. Henry Head and lessons learned from his self-experiment on radial nerve transection.

    In this paper the authors aim to review Dr. Henry Head's famous and dramatic nerve sectioning experiment. They discuss the implications of his experimental approach as well as the effect his experiment had on the field of neurology. Henry Head was a prominent British neurologist who contributed greatly to the understanding of the sensory examination through an experiment in which he had his own radial nerve transected. Head carefully documented the sensory changes following the sectioning. He hypothesized the existence of two separate sensory systems: protopathic and epicritic. Head was one of the first scientists to speculate on sensory dissociation, and his writings generated both enthusiasm and controversy. Although the ethical issue of self-experimentation was raised by his bold experiment and many aspects of his investigations and conclusions have been criticized, Head undoubtedly contributed important clinical lessons to neurology. Arguably, Henry Head's greatest contribution was the realization that the neurological portion of the sensory examination was anything but straightforward.

    2010-10-18

    The recent review of taxation in Australia - the Henry tax review - has recommended that the federal government increase the taxes already levied on tobacco and alcohol. Tobacco and alcohol taxes are put forward as the best way of reducing the social harms caused by the use and misuse of these substances. Junk foods have the same pattern of misuse and the same social costs as tobacco and alcohol. The Henry tax review rejects the idea of taxing fatty foods, and to date the government has not implemented a tax on junk food. We propose that a tax on junk food be implemented as a tool to reduce consumption and address the obesity epidemic.

    Gas-solid chromatography was used to determine the Henry`s law second gas-solid virial coefficients within the temperature range of 314--615 K for ethane, propane, butane, isobutane, pentane, hexane, heptane, chloromethane, dichloromethane, trichloromethane, tetrachloromethane, trichlorofluoromethane (Freon 11), chlorodifluoromethane (Freon 22), dichlorodifluoromethane (Freon 12), methyl ether, ethyl ether, and sulfur hexafluoride with Carbopack B, a microporous carbon adsorbent. The temperature dependence of the second gas-solid virial coefficients of these adsorbates was used in conjunction with analyses based on a graphical method, a single-surface numeric integration method, a single-surface analytic expression method, and a two-surface analytic expression method to determine the gas-solid interaction energies and other parameters. The interaction energies were correlated with a ratio of the critical temperature divided by the square root of the critical pressure. The four methods were compared in their abilities to successfully calculate second gas-solid virial coefficient values.

    Traditional models represent secondary organic aerosol (SOA) formation based on the gas-phase oxidation of a limited set of precursor molecules. However, these models tend to under-estimate the amounts and degree of oxygenation of actual SOA, indicating missing processes. One such source that has become increasingly important in recent years is glyoxal (CHOCHO, the smallest alpha-dicarbonyl). Unlike traditional SOA precursors, glyoxal forms SOA by partitioning to the aqueous phase according to Henry's Law. This work presents an analysis of Henry's Law constants for glyoxal uptake to laboratory-generated aerosols in a dynamically coupled gas-aerosol system. We combine CU LED-CE-DOAS measurements of gas-phase glyoxal with online HR-Tof-AMS and time-resolved HPLC ESI MS/MS particle-phase measurements to characterize the time resolved evolution of glyoxal partitioning, and relate molecular-specific measurements to AMS mass spectra. The experiments were performed in the simulation chamber facility at PSI, Switzerland, and investigate ammonium sulfate (AS), and mixed AS / fulvic acid seed aerosols under relative humidity conditions ranging from 50 to 85% RH. The Henry's Law and effective Henry's Law constants are compared with other values reported in the literature.

    2011-02-01

    In 1831, Henry invented a battery-powered rocking-beam motor that he later described as the first electromagnetic machine. He repeatedly modified the design over his career, but only one version of a motor actually constructed by Henry is known to exist. This version is in a collection of Henry instruments at Princeton University. We found that the Princeton motor cannot have operated in the form that was displayed as early as 1884. We found evidence in several historical documents and in the instrument itself that the field magnet shown with the motor is a mistake. Instead of a single horizontal bar magnet, the motor was designed to use two elliptical magnets. We presume the error was made by whoever assembled the first public display. We modeled the dynamics of Henry's vibrating motor and compared our results to the operation of a replica motor. Modeling provides insight into how the motor is able to vibrate indefinitely even in the presence of energy loss due to friction.

    The Illinois Department of Natural Resources-Office of Water Resources operates control structures on a reach of the Fox River in northeastern Illinois between McHenry and Algonquin. The structures maintain water levels in the river for flood-control and recreational purposes. This report documents flow ratings for hinged-crest gates, a broad-crested weir, sluice gates, and an ogee spillway on the control structures at McHenry and Algonquin. The ratings were determined by measuring headwater and tailwater stage along with streamflow at a wide range of flows at different gate openings. Standard control-structure rating techniques were used to rate each control structure. The control structures at McHenry consist of a 221-feet(ft)-long broad-crested weir, a 4-ft-wide fish ladder, a 50-ft-wide hinged-crest gate, five 13.75-ft-wide sluice gates, and a navigational lock. Sixty measurements were used to rate the McHenry structures. The control structures at Algonquin consist of a 242-ft-long ogee spillway and a 50-ft-wide hinged-crest gate. Forty-one measurements were used to rate the Algonquin control structures.

    Annual dissolved-solids load at the mouth of Henrys Fork was estimated by using data from U.S. Geological Survey streamflow-gaging station 09229500, Henrys Fork near Manila, Utah. The annual dissolved-solids load for water years 1970-2009 ranged from 18,300 tons in 1977 to 123,300 tons in 1983. Annual streamflows for this period ranged from 14,100 acre-feet in 1977 to 197,500 acre-feet in 1983. The 25-percent trimmed mean dissolved-solids load for water years 1970-2009 was 44,300 tons per year at Henrys Fork near Manila, Utah. Previous simulations using a SPAtially Referenced Regression On Watershed attributes (SPARROW) model for dissolved solids specific to water year 1991 conditions in the Upper Colorado River Basin predicted an annual dissolved-solids load of 25,000 tons for the Henrys Fork Basin upstream from Antelope Wash. On the basis of computed dissolved-solids load data from Henrys Fork near Manila, Utah, together with estimated annual dissolved-solids load from Antelope Wash and Peoples Canal, this prediction was adjusted to 37,200 tons. As determined by simulations with the Upper Colorado River Basin SPARROW model, approximately 56 percent (14,000 tons per year) of the dissolved-solids load at Henrys Fork upstream from Antelope Wash is associated with the 21,500 acres of irrigated agricultural lands in the upper Henrys Fork Basin.

    The temperature-dependent Henry's Law Constant for hydrogen peroxide was measured. The gas phase of hydrogen peroxide from the vapor saturator collected in a cryogenic trap was analyzed by a spectrophotometric determination, based on the oxidative decoloration of BPR (bromopryogallol red) reaction with hydrogen peroxide under the catalysis of hemin. At 10 degrees C - 35 degrees C, the relationship between Henry's Law constant K(H) (mol x L(-1) x atm(-1)) of hydrogen peroxide and temperature T (K) can be expressed as ln K(H) = a/T - b, where a = 7 269+/-22, and b = 13.26+/-0.08. The standard heat of hydrogen peroxide aqueous solution is 60.43+/-0.18 kJ x K(-1) x mol(-1).

    In multiple editions of his Principles and Practice of Medicine, a 1904 speech, and his essay “A Student Life,” Sir William Osler mentions and laments the death due to typhoid of his pupil, Henry W. Ochsner (1877–1902). Harvey Cushing, MD, in his biography of Osler, describes how deeply Osler was moved by “poor” Ochsner's death. Yet little is known about Ochsner. This article describes the life story, lineage, and death of Henry W. Ochsner, MD, a son of Swiss pioneers who settled in Waumandee, Wisconsin. He was a member of a family that includes medical luminaries (e.g., Albert J. Ochsner, MD, the famous Chicago surgeon, and Alton Ochsner, MD, the founder of the Ochsner Clinic); a brilliant student and physician; a humble and beloved fellow citizen; and a favorite pupil of Osler.

    There is a rich tradition of writings about the foundation of psychology laboratories, particularly in the United States but also in France. Various documents exist concerning former German laboratories in American and French literature. But the most interesting French paper was certainly written by a young psychologist named Victor Henri (1872-1940) who was a close collaborator of Alfred Binet (1857-1911) in the 1890s. Visiting various psychology laboratories, he wrote, in 1893, a clear description of the laboratories of Wundt, G. E. Müller, Martius and Ebbinghaus. An English translation is given of Henri's paper and the historical importance of his contribution is here expounded by contrasting the German and French psychologies of the time.

    Count Henri de Bonneval, was born in Bordeaux in 1806, in the line of descent of one of the most ancient French families of noble rank. He was assistant manager of the Strasbourg stud farm in 1830, when Louis-Philippe, an Orleanist, ascended to the throne of the Bourbon Charles X. As several other legitimists, Count Henri refused to take an oath to the new king and prefered to resign his position. Interested in medicine, he was deeply impressed by Hahnemann's Organon der Heilkunst and decided to leave France for KOthen, in Saxony, in order to learn homeopathy directly from its founder Back to France, he defended in Montpellier the first French medical thesis devoted to homeopathy and then opened a consulting room in Bordeaux. He rapidly gained a solid reputation and a large audience as a practitioner of homeopathy. At the same time, Henri acquired the Chateau de Latresne and the 500 acres surrounding land. He renovated and brought up to date the agricultural and wine-producing activities of the estate. The medical doctor soon proved to be an expert agronomist, extending his competence to the famous vineyard Chateau Canon of St. Emilion. Throughout his life, the Count showed notable qualities of philanthropy, materialized at Latresne by the construction of a church and, adjacent to the chapel, a boarding school, two classrooms and shelters for poor or sick old people. At the end of his life, Henri de Bonneval wrote a comprehensive book, that includes the presentation and discussions of the homeopathic methods, some philosophical reflections and personal memories.

  19. Henry constant and isosteric heat at zero-loading for gas adsorption in carbon nanotubes.

    2008-12-28

    The Henry constant and the isosteric heat of adsorption at zero loading in a carbon nanotube bundle are studied with Monte Carlo integration for the adsorption of gases over a range of temperatures. The spacing between nanotubes in a bundle is determined from the minimization of potential energy of interaction between these tubes. We study different tube configurations with bundles of 2, 3, 4 and 7 tubes. Depending on the configuration it is found that the spacing is of between 0.31 to 0.333 nm, and this falls within the range reported in the literature. The Henry constant has been carefully defined so that it will not become negative at high temperatures. This is done with the aid of accessible volume, rather than the usual absolute void volume. We show that linearity of the van't Hoff plot for the Henry constant is not strictly followed. Furthermore the slope of this plot is not equal to the isosteric heat of adsorption at zero loading, which is found to be a strong function of temperature. From the results we find that the Henry constant and the heat of adsorption depend on the tube configuration. In general the adsorption in the cusp interstices is strongest followed by that inside the tube and finally on the outer surface. However for very small tubes adsorption occurs inside the tube first. For molecules with orientation, the behaviour is even more interesting and the shape of the isosteric heat versus temperature depends on the degree of orientation, tube configuration and the domain of adsorption (interstices, inside the tube and on the outer surface).

    The total, soluble and insoluble oxalate contents of the leaves, stems and buds of Good-King-Henry (Blitum Bonus-Henricus) were extracted and measured using HPLC chromatography. The large, mature leaves contained 42% more total oxalate than in the small leaves and the soluble oxalate content of the large leaves was 33% higher than the smaller leaves. Cooking the mixed leaves, stems and buds in boiling water for two minutes significantly (p < 0.05) reduced the total oxalate when compared to the raw plant parts. Pesto sauce made from mixed leaves contained 257 mg total oxalate/100 g fresh weight; this was largely made up of insoluble oxalates (85% of the total oxalate content). Soup made from mixed leaves contained lower levels of total oxalates (44.26 ± 0.49 mg total oxalate/100 g fresh weight) and insoluble oxalate made up 49% of the oxalate contents. The levels of oxalates in the Good-King-Henry leaves were high, suggesting that the leaves should be consumed occasionally as a delicacy because of their unique taste rather than as a significant part of the diet. However, the products made from Good-King-Henry leaves indicated that larger amounts could be consumed as the oxalate levels were reduced by dilution and processing.

  2. On an isotherm thermodynamically consistent in Henry's region for describing gas adsorption in microporous materials.

    2010-05-15

    The Dubinin-Astakhov and Dubinin-Radushkevich isotherms, originally formulated from the classical volume filling theory of micropores, constitute the most accepted models for describing gas adsorption in microporous materials. The most important weakness of these equations relies on the fact that they do not reduce to Henry's law at low pressures, not providing therefore a proper characterization of adsorbents in the early stage of adsorption. In this paper, we propose a way out of this inherent problem using the thermodynamic isotherm developed in a previous study [J. Llorens, M. Pera-Titus, J. Colloid Interface Sci. 331 (2009) 302]. This isotherm allows the generation of a series of equations that make available a comprehensive description of gas adsorption for the whole set of relative pressures (including Henry's region), also providing explicit information about energy heterogeneity of the adsorbent through the two characteristic m parameters of the thermodynamic isotherm (i.e., m(1) and m(2)). The obtained isotherm converges into the Dubinin-Astakhov isotherm for relative pressures higher than 0.1, the characteristic α parameter of this isotherm being expressed as α=m(2)-1 and the affinity coefficient (β) as a sole function of m(2). An expression differing from the Dubinin-Astakhov isotherm has been obtained for describing Henry's region, providing relevant information about confinement effects when applied to zeolites.

    A novel bis-thiourea BINAM-based catalyst for the asymmetric aza-Henry reaction has been developed. This catalyst promotes the reaction of N-Boc imines with nitroalkanes to afford β-nitroamines with good yields and high enantioselectivities. This catalyst has the advantage that it can be prepared in a single step from commercially available materials. A model is proposed for the catalyst action where the both components of the reaction are activated simultaneously by hydrogen bonding. Regardless of the mechanism, the success of the present catalyst demonstrates the potential of bis-thioureas as an interesting class of relatively unexplored catalysts. PMID:23795151

    The present paper gives an account of part of the stage theory of early child development of the French theorist Henri Wallon (1879-1962). Unlike his contemporary Jean Piaget, Wallon concentrated his efforts upon a description of the child's emotional development and the role emotions play in establishing the bond between child and caregiver. The description of Wallon's stage theory is preceded by biographical information and a presentation of his methodological views. It is argued that Wallon's theory is unique in its focus, exerted influence upon theorists such as Lev Vygotsky, and is basically compatible with modern insights about the nature of child development and the growth of intersubjectivity.

We present analytical solutions that provide the concentrations of the enzyme (E), the substrate (S), as well as those of the enzyme-substrate complex (C), and the product (P) as functions of time. For k (2) small compared to k (-1), we properly describe the entire enzymatic activity from the beginning of the reaction up to longer times without imposing extra conditions on the initial concentrations E ( o ) and S ( o ), which can be comparable or much different.

    There have been growing interests in modeling studies to understand oxidation of volatile organic compounds in the gas phase and their mass transfer to the aqueous phase for their potential roles in cloud chemistry, formation of secondary organic aerosols, and fate of atmospheric organics. Temperature-dependent Henry's law constants, key parameters in the atmospheric models to account for mass transfer, are often unavailable. In the present work, we investigated gas-liquid equilibriums of isoprene, limonene, α-pinene, and linalool using a bubble column technique. These compounds, originating from biogenic sources, were selected for their implications in atmospheric cloud chemistry and secondary organic aerosol formation. We reported Henry's law constants (K(H)), first order loss rates (k), and gas phase diffusion coefficients over a range of temperatures relevant to the lower atmosphere (278-298 K) for the first time. The measurement results of K(H) values for isoprene, limonene, α-pinene, and linalool at 298 K were 0.036 ± 0.003; 0.048 ± 0.004; 0.029 ± 0.004; and 21.20 ± 0.30 mol L(-1) atm(-1), respectively. The fraction for these compounds in stratocumulus and cumulonimbus clouds at 278 K were also estimated in this work (isoprene, 1.0 × 10(-6), 6.8 × 10(-6); limonene, 1.5 × 10(-6), 1.0 × 10(-5); α-pinene, 4.5 × 10(-7), 3.1 × 10(-6); and linalool, 6.2 × 10(-4), 4.2 × 10(-3)). Our measurements in combination with literature results indicated that noncyclic alkenes could have smaller K(H) values than those of cyclic terpenes and that K(H) values may increase with an increasing number of double bonds. It was also shown that estimated Henry's law constants and their temperature dependence based on model prediction can differ from experimental results considerably and that direct measurements of temperature-dependent Henry's law constants of atmospheric organics are necessary for future work.

    This article establishes the biography of a little known physician of the 19th century., whose commitment with orthopaedics and formulation of medical gymnastics was important: the surgeon-orthopaedist Sauveur-Henri-Victor Bouvier. Several constitutive processes of the medical field of the 19th century are analysed: specialization (around orthopaedics), professionalization and development of various therapeutic and hygienic methods (among them medical gymnastics). Bouvier's biography is particularly instructive and sheds new light on these different processes, as well as on the institutionalization of orthopaedics from the 1820's up to the 1870's, at the intersection between medical and educative fields, between hospital, medical faculty and teaching of gymnastics.

    Correlations were developed and used to calculate gas-solid interaction energy parameters which in turn were used to calculate Henry's law constants for the adsorption of a series of hydrocarbons and chlorofluorocarbons on either a 13X zeolite or a microporous carbon, SuperSorb. The adsorption energetic parameter was correlated with the boiling point, critical constant ratio (critical temperature divided by the square root of the critical pressure), number of carbon atoms, and molecular structure or atomic structure of the adsorbate molecule. These correlations were used to calculate gas-solid interaction energies and, with a selection of the gas-solid interaction potential parameters, were used in an integral expression to calculate the gas-solid virial coefficients. The critical constant ratio was found to provide the best means of predicting the gas-solid interaction energy and the corresponding second gas-solid virial coefficient. This approach could be used to predict the extent adsorption in the Henry's law region using only adsorbate molecular properties where energy correlations have been previously established for a series of adsorbate molecules.

    During his house staff training before World War II, Dr. W. Proctor Harvey encountered Dr. Samuel A. Levine at the Peter Bent Brigham Hospital in Boston. Following military service, Harvey returned to Boston and became Levine's first cardiology fellow. The book Clinical Auscultation of the Heart--the Little Green Book by Levine and Harvey in 1949 combined Levine's clinical wisdom with Harvey's objective phonocardiographic methods and brought an important objective dimension to the art of cardiac auscultation. Both Levine and Harvey shared experiences and friendship with Henry Christian, the first Physician-in-Chief when the new Brigham Hospital Opened in 1913. Christian, appointed Dean of the Harvard Medical School in 1908 at the age of 32, was referred to as the "Boy Dean." He held the Hersey Chair of Theory and Practice of Physic from 1908 until 1939, was one of the founding group of the American Society for Clinical Investigation, and a major force in academic medicine. Levine served as intern to Christian and then joined the Brigham medical staff in 1915. Proctor Harvey followed Henry Christian's path from their mutual hometown of Lyunchburg, VA to the Peter Bent Brigham Hospital. A series of illuminating and respectful professional interactions--initially between Christian and Levine, between Levine and Harvey in the early 1940s, and between Harvey and Christian in the 1950s--provide the background for the genesis of the Little Green Book and a remarkable example of academic heritage.

    Childhood obesity has reached epidemic levels, yet many health professionals lack confidence in working with parents around lifestyle change. HENRY (Health Exercise Nutrition for the Really Young) aims to tackle this through training practitioners to work more effectively with parents of preschoolers around obesity and lifestyle issues.We evaluated the long-term impact of HENRY training on health professionals' knowledge, skills and confidence in tackling obesity prevention. All practitioners trained 2007-11 (n = 1601) were invited to complete an online survey. 237 emails (14.8%) were undeliverable; 354 (26.0%) of the remainder completed the survey. A majority (67%) reported using knowledge and skills gained on a regular basis in their professional lives. Sessions on the importance of empathy and key parenting skills were considered particularly useful, with 78% and 74% respectively reporting regular use of these skills. Effects on respondents' personal lives were also reported: 61% applied the knowledge and skills at home, identifying for example, more shared family mealtimes and reduced portion sizes. The impact endures, with 71% of those undergoing training > 12 months ago, stating that they continued to use concepts in their professional lives. The findings suggest that brief training can have a sustained impact on practitioners' professional and personal lives.

    1970-01-01

    The lower Henrys Fork region in eastern Idaho includes the plains and low benches between Ashton and the junction of Henrys Fork and Snake River. The northwestern and western parts of the area are part of the Snake River basalt plain. The central part of the area is occupied by alluvial plains of the Snake, Teton, and Falls Rivers and of Henrys Fork. The alluvial deposits are underlain by basalt. The southeastern part of the area is a bench (Rexburg Bench), chiefly on silicic and basaltic volcanic rocks, which rises gradually to mountain peaks (Big Hole Mountains) southeast of the area. Irrigation wells open to the basalt under the Snake River Plain and the basalt and sands and gravels under the alluvial plains yield large amounts of water with small drawdowns. Irrigation wells in the silicic volcanic rocks and the interbedded ash, pyroclastics, and sedimentary deposits beneath the Rexburg Bench generally yield much less water. The regional water table slopes southwestward beneath the basalt and alluvial plains. It is recharged by precipitation that infiltrates into the ground in the headwaters of Henrys Fork and Falls, and Teton Rivers and by water that moves downward from an extensive perched water body caused by seepage from stream channels and surface-water irrigation. The perched water in part moves vertically down to the regional water table and in part laterally to the streams. Ground water beneath the Rexburg Bench moves generally northwestward to join the regional ground-water body beneath the alluvia,1 and basalt plain, but this area contributes very little recharge to the main aquifer body. Recharge to the regional water table is estimated to average 725,000 acre-feet annually. The regional water table is below the level of the streams in the area, and ground water in the main aquifer, therefore, is not tributary to the streams. Pumping from the regional ground-water reservoir for irrigation or other uses would have no effect on streamflow or surface

  17. Smog chamber experiments to investigate Henry's law constants of glyoxal using different seed aerosols

    NASA Astrophysics Data System (ADS)

    Jakob, Ronit

    2014-05-01

    Aerosols play an important role in the chemistry and physics of the atmosphere. Hence, they have a direct as well as an indirect impact on the earth's climate. Depending on their formation, one distinguishes between primary and secondary aerosols[1]. Important groups within the secondary aerosols are the secondary organic aerosols (SOAs). In order to improve predictions about these impacts on the earth's climate the existing models need to be optimized, because they still underestimate SOA formation[2]. Glyoxal, the smallest α-dicarbonyl, not only acts as a tracer for SOA formation but also as a direct contributor to SOA. Because glyoxal has such a high vapour pressure, it was common knowledge that it does not take part in gas-particle partitioning and therefore has no impact on direct SOA formation. However, the Henry's law constant for glyoxal is surprisingly high. This has been explained by the hydration of the aldehyde groups, which means that a species with a lower vapour pressure is produced. Therefore the distribution of glyoxal between gas- and particle phase is atmospherically relevant and the direct contribution of glyoxal to SOA can no longer be neglected. A high salt concentration present in chamber seed aerosols leads to an enhanced glyoxal uptake into the particle. This effect is called "salting-in". The salting effect depends on the composition of the seed aerosol as well as the soluble compound. For very polar compounds, like glyoxal, a "salting-in" is observed[3]. Glyoxal particle formation during a smog chamber campaign at Paul-Scherrer-Institut (PSI) in Switzerland was examined using different seed aerosols such as ammonium sulfate, sodium chloride and sodium nitrate. The aim of this campaign was to investigate Henry's law constants for different seed aerosols. During the campaign filter samples were taken to investigate the amount of glyoxal in the particle phase. After filter extraction, the analyte was derivatized and measured using UHPLC

  9. Significance of the Henri-Michaelis-Menten theory in abiotic catalysis: catechol oxidation by δ-MnO 2

    Naidja, A.; Huang, P. M.

    2002-05-01

    The Henri-Michaelis-Menten theory, for more than eight decades, was only restricted to homogeneous enzymatic catalysis. A mimic of an enzymatic kinetics based on the Henri-Michaelis-Menten concept was experimentally observed in heterogeneous catalysis in the present study with δ-MnO 2 as an abiotic catalyst in the oxidation of catechol (1,2-dihydroxybenzene). Using the derived linear forms of Lineweaver-Burk or Hofstee, the data show that similar to the enzyme tyrosinase, the kinetics of the catechol oxidation catalyzed by δ-MnO 2 can be described by the Henri-Michaelis-Menten equation, V0= VmaxS/( Km+ S), where Vmax is the maximum velocity and Km the concentration of the substrate ( S) corresponding to an initial velocity ( V0) half of Vmax. By analogy to the enzymatic kinetics, the parameters Vmax and Km for an heterogeneous abiotic catalysis were derived for the first time. Further, based on the concentration of the active centers of the mineral oxide, the kinetic constants kcat and kcat/ Km, respectively, representing the turnover frequency and the efficiency of the mineral catalyst, were also determined from the derived general rate equation of Briggs and Haldane. As an abiotic catalyst, δ-MnO 2 has a paramount role in the oxidation of phenolic compounds in soil, sediment and water environments. Therefore, the present observation is of fundamental and practical significance in elucidating the affinity between an abiotic catalyst and a substrate based on the Henri-Michaelis-Menten theory.

    2014-10-01

    Historians have long maintained that pneumonia killed William Henry Harrison (1773-1841) just 1 month after he became the ninth president of the United States. For more than a century and a half, it has been alleged that the aged Harrison caught a fatal chill the day he was sworn into office while delivering an overly long inaugural address in wet, freezing weather without a hat, overcoat, and gloves. However, a careful review of the detailed case summary written by his personal physician suggests that enteric fever, not pneumonia per se, was the disorder that carried off "Old Tippecanoe." Two other presidents of that era, James Knox Polk and Zachary Taylor, also developed severe gastroenteritis while in office. Taylor's illness, like Harrison's, proved fatal. In all 3 cases, the illnesses were likely a consequence of the unsanitary conditions that existed in the nation's capital during most of the nineteenth century.

  11. The biologist as psychologist: Henry Fairfield Osborn's early mental ability investigations.

    PubMed

    Young, Jacy L

    2012-01-01

    In the early 1880s, biologist Henry Fairfield Osborn conducted some of the first questionnaire research in American psychology. This article details how he came to distribute Francis Galton's questionnaire on mental imagery in the United States, as well as how he altered it to suit his own burgeoning psychological research interests. The development and circulation of questionnaires at the very beginning of American scientific psychology, first by Osborn and later by G. Stanley Hall, is discussed in terms of the new psychology's often-overlooked methodological plurality. Further, Osborn's late nineteenth century interest in individual variation and group differences in mental imagery ability are discussed in relation to his pervasive educational and social concerns, as well as his eventual status as a prominent eugenicist in the twentieth century United States. This research into mental imagery ability foreshadows the eugenic-oriented intelligence testing that developed in the early twentieth century.

  12. The inertia of sex: Henry Adams on family and the politics of unconditional love.

    PubMed

    Duff, Brian

    2010-01-01

    This article offers a reassessment of the contemporary relevance of the political thought of Henry Adams through a focus on his ideas about the relationship between family and politics. Adams' ideas have been dismissed by contemporary thinkers, like Richard Rorty, who rely on similar ideas about the role family should play in politics. The article traces the role of ideas about family as a unifying theme in Adams' history, fiction, and autobiography. It shows both why Adams believed familial sentiments, especially feminine and motherly love, were crucial to political unity, and why he thought these sentiments had become increasingly difficult to rely upon. In showing how Adams wrestled with the difficulties that emerge in putting familial sentiments to use for politics, the article suggests that Adams' ideas offer useful lessons for contemporary thinkers interested in the relationship between family and politics.

    During the years of World War II, the American Association for the History of Medicine fostered a Pan-American policy aimed at establishing relationships with Latin American historians of medicine. Juan R. Beltrán, professor of history of medicine at the University of Buenos Aires, also pursued an energetic program of academic diplomacy. The correspondence between Henry Sigerist and Beltrán makes manifest that by 1941 good channels of communication were established between Baltimore and Buenos Aires, but the friendly links did not last long. The motives for this can be found in the competing aims of the AAHM and Beltrán, and the pattern of international relationships during the war years.

  14. Henry H. Cheek and transformism: new light on Charles Darwin's Edinburgh background

    2015-01-01

    Evidence for the transformist ideas espoused by Henry H. Cheek (1807–33), a contemporary of Charles Darwin's at the University of Edinburgh, sheds new light on the intellectual environment of Edinburgh in the late 1820s and early 1830s. Cheek was the author of several papers dealing with the transmutation of species influenced by the theories of Étienne Geoffroy Saint-Hilaire (1772–1844), Jean-Baptiste Lamarck (1744–1829) and the Comte de Buffon (1707–88). Some of these were read to student societies, others appeared in the Edinburgh Journal of Natural and Geographical Science, which Cheek edited between 1829 and 1831. His writings give us a valuable window onto some of the transformist theories that were circulating among Darwin's fellow medical students in the late 1820s, to which Darwin would have been exposed during his time in Edinburgh, and for which little other concrete evidence survives.

    2013-04-01

    Success with the medical management of pain grew tremendously after William Thomas Green Morton's successful demonstration of surgical anesthesia in 1846: Henry K. Beecher's clinical and experimental contributions to anesthesia during and after World War II had a profound impact on how clinicians and experimentalists study human populations in medicine. Beecher found that pain research required human subjects because pain was different for each individual. Nearly 100 years before Beecher, Claude Bernard similarly considered the complexity and uniqueness of human research subjects. Bernard and Beecher both preferred animal subjects in research when appropriate, but suggested that studies involving some mental, bodily, and cognitive processes required human subjects. Although Beecher and Bernard's lives did not overlap, these two men similarly confronted the issues of complexity in human and animal research, particularly in those phenomena involving higher cognitive functions.

    2016-01-01

    Henry Knowles Beecher, an icon of human research ethics, and Timothy Francis Leary, a guru of the counterculture, are bound together in history by the synthetic hallucinogen lysergic acid diethylamide (LSD). Both were associated with Harvard University during a critical period in their careers and of drastic social change. To all appearances the first was a paragon of the establishment and a constructive if complex hero, the second a rebel and a criminal, a rogue and a scoundrel. Although there is no evidence they ever met, Beecher's indirect struggle with Leary over control of the 20th century's most celebrated psychedelic was at the very heart of his views about the legitimate, responsible investigator. That struggle also proves to be a revealing bellwether of the increasingly formalized scrutiny of human experiments that was then taking shape.

    The projection of Henry VIII in the first half of his reign, which began in 1509, is of a magnificent and accomplished 'imperial prince', the possessor of superb physical health. In 1528, when aged 37, he showed a marked change in personality due, it is here argued, to depressive illness, from which he recovered by the mid-1530s. Such ill health has not been recognized previously and it engenders a need for a reassessment of his character and actions during these years of illness. He did not suffer from syphilis and the well-known leg ulcers were less incapacitating than has been described in the past. This truly enormous and overweight man was 55 years old when he died in 1547 in chronic heart failure.

    The properties of condensed matter are strongly affected by confinement and size effects at the nanoscale. Herein, we measured by microvolumetry the increased solubility of H(2) in a series of solvents (CHCl(3), CCl(4), n-hexane, ethanol, and water) when confined in the cavities of mesoporous solids (gamma-alumina, silica, and MCM-41). Gas/liquid solubilities are enhanced by up to 15 times over the corresponding bulk values for nanoliquid sizes smaller than 15 nm as long as gas/liquid interfaces are mesoconfined in a porous network. Although Henry's law constant apparently no longer applies under these confinement, the concentration of dissolved H(2) still increases linearly with increasing pressure in the range 1-5 bar. We discuss the role and main implications of surface excess concentrations at mesoconfined gas/liquid interfaces in enhancing gas solubility.

    Style is a familiar category for the analysis of art. It is less so in the history of anatomical illustration. The great Renaissance and Baroque picture books of anatomy illustrated with stylish woodcuts and engravings, such as those by Charles Estienne, Andreas Vesalius and Govard Bidloo, showed figures in dramatic action in keeping with philosophical and theological ideas about human nature. Parallels can be found in paintings of the period, such as those by Titian, Michelangelo and Hans Baldung Grien. The anatomists also claimed to portray the body in an objective manner, and showed themselves as heroes of the discovery of human knowledge. Rembrandt’s painting of Dr Nicholas Tulp is the best-known image of the anatomist as hero. The British empirical tradition in the 18th century saw William Cheselden and William Hunter working with techniques of representation that were intended to guarantee detailed realism. The ambition to portray forms life-size led to massive volumes, such as those by Antonio Mascagni. John Bell, the Scottish anatomist, criticized the size and pretensions of the earlier books and argued for a plain style adapted to the needs of teaching and surgery. Henry Gray’s famous Anatomy of 1858, illustrated by Henry Vandyke Carter, aspired to a simple descriptive mode of functional representation that avoided stylishness, resulting in a style of its own. Successive editions of Gray progressively saw the replacement of Gray’s method and of all his illustrations. The 150th anniversary edition, edited by Susan Standring, radically re-thinks the role of Gray’s book within the teaching of medicine. PMID:20447244

    Henry Solomon Wellcome, the famous drug manufacturer had a fascinating association with the Sudan. Besides supporting tropical medicine research in this country, he established an extensive project in the Sudan that aimed at combining archeological excavations, philanthropy and social reform. This article is an archives-based account on this side of Wellcome’s association with the Sudan. The article starts with Wellcome’s early years in the American Midwest and the evolution of his career and his rise as a world-renowned drug manufacturer. After the battle of Omdurman, Wellcome visited Sudan in 1900 – 1901 where he offered to support the establishment of the research laboratories which later came to be known as the Wellcome Tropical Research Laboratories in Khartoum. He then became directly involved in the planning and running of extensive archeological excavations in the central Sudan. This project served as a field in which Wellcome found an outlet for his philanthropy. More than 4000 labourers were employed in Jebel Moya. Professional archeologists and anatomists were recruited by Wellcome to supervise the work, and all the requirements in terms of equipment were catered for. Wellcome devised a Savings Bank System whereby part of the earnings of each labourer were saved to him till the end of the season. He also introduced one of his innovations: aerial photography using box kite which was used for the first time in archeology. Wellcome made it a rule that no applicant should be turned away. The Camp Commandant had to find suitable work for each applicant, including the handicapped who were assigned to appropriate jobs like mending baskets or cutting grass for building huts. Wellcome’s welfare work had a significant impact on the local inhabitants of Jebel Moya. Henry Solomon Wellcome, 1906. Oil painting by Hugh Goldwin Riviere. Credit: Wellcome Library PMID:27493379

    It is easy to pick out my most memorable meeting of the AAS: the 149th meeting held in January, 1977, and hosted by the University of Hawaii, in Honolulu, HI. It was the meeting at which two traditions of the Society were broken, and we moved into the era of equal opportunity for women astronomers. Cecilia Payne-Gaposchkin received the highest award of the AAS: the Henry Norris Russell Lectureship. This award had never before been available to women, otherwise Cecilia would, years earlier, have been honored for the many achievements in her lifetime of renowned astronomical research. And I, the first woman to be elected President of the AAS, had the honor of presenting the illuminated scroll to Cecilia, and of introducing her on the platform where she delivered the Henry Norris Russell Prize Lecture, entitled ``Fifty Years of Novae"(1) . Cecilia opened by comparing the experience of young and old scientists in achieving exciting results from their research, and then led us through the history of the discoveries of and about some famous novae. She described the physical picture that emerged from studies of their light curves, their spectra, and the discovery of their binary nature. Three important tables were included, listing data on cataclysmic binaries (dwarf novae) and their link to the nova phenomenon in general. She recalled that she and Sergei Gaposchkin had hesitated between the names catastrophic and cataclysmic for the dwarf novae, and decided on the latter, from the dictionary definitions of those two terms: ``a cataclysm is a great and general flood" while a catastrophe ``is a final event". The nova phenomenon is recurrent, as are the dwarf novae, and both involve an outpouring of a flood of energy. She concluded by describing her 50 years' experience with novae as presenting ``the contemporary portrait of a nova", rather than a final picture, and by forecasting that the next 50 years of discovering and studying novae will be as full of surprises as the

    1988-01-01

    Twenty-three measurement of discharge were used to determine discharge ratings for the five adjustable sluice gates, spillway and fish ladder at McHenry Dam on the Fox River in Illinois. Discharge ratings were determined for free weir, free orifice, and submerged orifice flow regimes. Hydraulic conditions that identify flow regimes at McHenry Dam are defined by ratios between headwater depth (h1), tailwater depth (h3), and gate opening (hg). Flow under the sluice gates is identified as weir flow when the ratio of gate opening to headwater depth is greater than 0.73, and as orifice flow when hg/H1 is less than 0.73. Free orifice flow occurs when the ratio of tailwater depth to gate opening is less than 1.3, and submerged orifice flow occurs when h3/hg is greater than 1.3. Flow under the sluice gates is identified as free weir flow when the ratio of tailwater depth to headwater depth is less than 0.75, and as submerged weir flow when h3/h1 is greater than 0.75. Flow over the spillway is identified as free weir flow when the ratio of tailwater depth to headwater depth is less than 0.60, and as submerged weir flow when h3/h1 is greater than 0.60. Discharge coefficients to be used in equations to compute discharge for various hydraulic conditions were determined. Four discharge measurement, ranging from 169 to 2990 cu ft/sec, were used to define discharge coefficients that varies from 2.61 to 3.14 for free weir flow over the spillway. Nineteen discharge measurements, ranging from 180 to 4050 cu ft/sec, were used to define discharge coefficients for free weir, free orifice, and submerged orifice flow under the sluice gates. The average value of the discharge coefficient for free weir flow under the sluice gates is 3.17. Discharge coefficients for free orifice flow varied from 0.48 to 0.66 and the discharge coefficients for submerged orifice flow from the two measurements were 0.59 and 0.67. (Author 's abstract)

    A diastereo- and enantioselective Michael/Henry/ketalization sequence to functionalized tetrahydropyrans is described. The multicomponent cascade reaction uses acetylacetone or β-keto esters, β-nitrostyrenes, and alkynyl aldehydes as substrates affording tetrahydropyrans with five contiguous stereocenters. Employing a bifunctional quinine-based squaramide organocatalyst, the title compounds are obtained in moderate to good yields (27–80%), excellent enantiomeric excesses (93–99% ee), and high diastereomeric ratios (dr > 20:1) after one crystallization.

    A mummified head was identified in 2010 as belonging to Henri IV, King of France. A putative blood sample from the King Louis XVI preserved into a pyrographically decorated gourd was analyzed in 2011. Both kings are in a direct male-line descent, separated by seven generations. We have retrieved the hypervariable region 1 of the mitochondrial DNA as well as a partial Y-chromosome profile from Henri IV. Five STR loci match the alleles found in Louis XVI, while another locus shows an allele that is just one mutation step apart. Taking into consideration that the partial Y-chromosome profile is extremely rare in modern human databases, we concluded that both males could be paternally related. The likelihood ratio of the two samples belonging to males separated by seven generations (as opposed to unrelated males) was estimated as 246.3, with a 95% confidence interval between 44.2 and 9729. Historically speaking, this forensic DNA data would confirm the identity of the previous Louis XVI sample, and give another positive argument for the authenticity of the head of Henri IV.

    The Henry's law constant ( H) is an important parameter that is required to estimate the air-water exchange of semi-volatile organic compounds. Henry's law constants for 17 banned/restricted/currently used organochlorine pesticides (OCPs) were experimentally determined using a gas-stripping technique in deionized and saline water (3%) over a temperature range of 5-35 °C. H values (at 25 °C) ranged between 0.066±0.037 Pa m 3 mol -1 (endosulfan II) and 62.0±24.2 Pa m 3 mol -1 (heptachlor) in deionized water while the range in saline water was 0.28±0.03 Pa m 3 mol -1 ( γ-HCH) and 135.2±31.3 Pa m 3 mol -1 (heptachlor). The increase in dimensionless Henry's law constants ( H') for OCPs over the studied temperature range was between 3 ( γ-HCH)-19 times (chlorpyrifos) and 3 (endosulfan II)-80 times ( trans-nonachlor) in deionized and saline water, respectively. The calculated enthalpies of phase change (Δ HH) were within the ranges previously reported for OCPs and other organic compounds (23.8-100.2 kJ mol -1). The salting-out constant, ks, ranged between 0.04 ( γ-HCH) and 1.80 L mol -1 (endosulfan II) indicating the importance of assessing the H values of OCPs in saline water to accurately determine their partitioning and fate in seawater.

    A mineral-resource survey of the 350-acre Henry's Lake Wilderness Study Area (ID-035-077) was made in 1986-87. No identified resources (known) or currently active claims exist within or adjacent to the wilderness study area. There is potential for several types of undiscovered mineral resources within the study area. The southwestern part of the wilderness study area, along the Madison Range fault, is rated as having a moderate energy-resource potential for geothermal water; the remainder of the study area has a low potential for resources of this commodity. A small outcrop of marble in the southernmost part of the study area has a low mineral-resource potential for talc; for talc in marble possibly concealed beneath the study area the mineral-resource potential is rated as unknown. The study area has a low mineral-resource potential for iron in hematite-mineralized amphibolite gneiss, and for gold, silver, and uranium. The area has no mineral-resource potential for phosphate, because the host strata have been eroded; and no resource potential for oil and gas.

    Henry Cavendish (1731-1810) was an outstanding chemist and physicist. Although he was not a major figure in the history of respiratory physiology he made important discoveries concerning hydrogen, carbon dioxide, atmospheric air, and water. Hydrogen had been prepared earlier by Boyle but its properties had not been recognized; Cavendish described these in detail, including the density of the gas. Carbon dioxide had also previously been studied by Black, but Cavendish clarified its properties and measured its density. He was the first person to accurately analyze atmospheric air and reported an oxygen concentration very close to the currently accepted value. When he removed all the oxygen and nitrogen from an air sample, he found that there was a residual portion of about 0.8% that he could not characterize. Later this was shown to be argon. He produced large amounts of water by burning hydrogen in oxygen and recognized that these were its only constituents. Cavendish also worked on electricity and heat. However, his main contribution outside chemistry was an audacious experiment to measure the density of the earth, which he referred to as "weighing the world." This involved determining the gravitational attraction between lead spheres in a specially constructed building. Although this was a simple experiment in principle, there were numerous complexities that he overcame with meticulous attention to experimental details. His result was very close to the modern accepted value. The Cavendish Experiment, as it is called, assures his place in the history of science.

    The modern history of experimentation with human beings is notable for its ethical lacunae, when even the clearest directives fail to prevent violations of subjects' rights and welfare. One such lacuna occurred during the 25 years between 1947, when the Nuremberg Code was articulated in the judgment passed on the men who had performed medical experiments in the Nazi concentration camps, and 1972, when the revelation of the 40-year-long Tuskegee Syphilis Study shocked the public and pushed Congress to adopt legislation that eventually transformed the governance of human subjects research. The work that Henry Beecher and Jay Katz did on the ethics of human experimentation beginning in 1964-which was mutually supportive but also divergent in its premises and prescriptions-played a prominent role in the policy-making processes. Beecher, whose detailed disclosure of the ethical lapses of leading researchers in his renowned 1966 New England Journal of Medicine article initiated the policy reform process, proved less influential in shaping those reforms than Katz. Ultimately, Beecher was one of the last and best exemplars of "medical ethics," while Katz-in his service on the Tuskegee Syphilis Study Ad Hoc Advisory Panel and in his testimony before, and work with, the Senate Health subcommittee-was an early practitioner of bioethics, a field in which the rules are not all written and applied by the medical profession but arise through a messier process involving outsiders and formal regulatory decisions.

    The reversible partitioning of glyoxal was studied in simulation chamber experiments for the first time by time-resolved measurements of gas-phase and particle-phase concentrations in sulfate-containing aerosols. Two complementary methods for the measurement of glyoxal particle-phase concentrations are compared: (1) an offline method utilizing filter sampling of chamber aerosols followed by HPLC-MS/MS analysis and (2) positive matrix factorization (PMF) analysis of aerosol mass spectrometer (AMS) data. Ammonium sulfate (AS) and internally mixed ammonium sulfate/fulvic acid (AS/FA) seed aerosols both show an exponential increase of effective Henry's law coefficients (KH,eff) with AS concentration (cAS, in mol kg(-1) aerosol liquid water, m = molality) and sulfate ionic strength, I(SO4(2-)) (m). A modified Setschenow plot confirmed that "salting-in" of glyoxal is responsible for the increased partitioning. The salting constant for glyoxal in AS is K(S)CHOCHO = (-0.24 ± 0.02) m(-1), and found to be independent of the presence of FA. The reversible glyoxal uptake can be described by two distinct reservoirs for monomers and higher molecular weight species filling up at characteristic time constants. These time constants are τ1 ≈ 10(2) s and τ2 ≈ 10(4) s at cAS < 12 m, and about 1-2 orders of magnitude slower at higher cAS, suggesting that glyoxal uptake is kinetically limited at high salt concentrations.

    Henry E. Sigerist, an internationally renowned medical historian, played a surprisingly important and visible role in American medical politics in the 1930s and 1940s. Born in Paris of Swiss parents, he was professor in Leipzig, Germany, before coming to the United States in 1932 as professor of the history of medicine at Johns Hopkins University. Once in America. Sigerist became deeply involved in medical politics and the campaign for national health insurance. He argued that individualized medical practice was outdated and should gradually be superseded by state-run and state-financed health services. National health insurance was but one step in this historical progression. Sigerist thus lent the weight of history itself to the cause of medical care reform. The charming and erudite Sigerist was welcomed by the leaders of academic medicine in America. Soon, he emerged as a spokesman of the left wing of the medical profession, an effective and popular speaker and an impassioned advocate of socialized medicine. This paper traces Sigerist's political ideas and activities, and his contributions toward medical care reform in the United States. Images p1639-a p1642-a PMID:8916536

    Primary data for the temperature dependent solubility of HCN in water do not presently exist for low concentrations of HCN at environmentally or physiologically relevant temperatures. Henry's Law constant (K(H), M/atm) for the vapor-solution equilibrium of HCN was determined in 0.1 M sodium phosphate buffer (adjusted to pH 9.00 +/- 0.03 at 296.6 +/- 0.1 K) from 287-311 K. Stable gas phase concentrations of HCN are generated by established techniques, via air equilibration of aqueous cyanide partitioned by a microporous membrane. The effluent gaseous HCN, in equilibrium with the constant temperature aqueous cyanide, was collected in dilute NaOH and determined by a spectrophotometrically using cobinamide. The K(H) of HCN may be expressed as ln K(H) (M/atm) = (8205.7 +/- 341.9)/T - (25.323 +/- 1.144); r(2) = 0.9914) where T is the absolute temperature in K. This corresponds to 9.02 and 3.00 M/atm at 25 and 37.4 degrees C, respectively, compared to actual measurements of 9.86 and 3.22 at 25.0 and 37.8 degrees C, respectively. The technique also allows for convenient generation of trace levels of HCN at ppbv-ppmv levels that can be further diluted.

    The two-dimensional model CE-QUAL-W2 was used to simulate hydrodynamics, temperature, and water quality in Henry Hagg Lake, Oregon, for the years 2000 through 2003. Input data included lake bathymetry, meteorologic conditions, tributary inflows, tributary temperature and water quality, and lake outflows. Calibrated constituents included lake hydrodynamics, water temperature, orthophosphate, total phosphorus, ammonia, algae, chlorophyll a, zooplankton, and dissolved oxygen. Other simulated constituents included nitrate, dissolved and particulate organic matter, dissolved solids, and suspended sediment. Two algal groups (blue-green algae, and all other algae) were included in the model to simulate the lakes algal communities. Measured lake stage data were used to calibrate the lakes water balance; calibration of water temperature and water quality relied upon vertical profile data taken in the deepest part of the lake near the dam. The model initially was calibrated with data from 200001 and tested with data from 200203. Sensitivity tests were performed to examine the response of the model to specific parameters and coefficients, including the light-extinction coefficient, wind speed, tributary inflows of phosphorus, nitrogen and organic matter, sediment oxygen demand, algal growth rates, and zooplankton feeding preference factors.

    This paper presents an approach for producing aquifer sensitivity maps from three-dimensional geologic maps, called stack-unit maps. Stack-unit maps depict the succession of geologic materials to a given depth, and aquifer sensitivity maps interpret the successions according to their ability to transmit potential contaminants. Using McHenry County, Illinois, as a case study, stack-unit maps and an aquifer sensitivity assessment were made to help land-use planners, public health officials, consultants, developers, and the public make informed decisions regarding land use. A map of aquifer sensitivity is important for planning because the county is one of the fastest growing counties in the nation, and highly vulnerable sand and gravel aquifers occur within 6 m of ground surface over 75% of its area. The aquifer sensitivity map can provide guidance to regulators seeking optimal protection of groundwater resources where these resources are particularly vulnerable. In addition, the map can be used to help officials direct waste-disposal and industrial facilities and other sensitive land-use practices to areas where the least damage is likely to occur, thereby reducing potential future liabilities.

  19. About and beyond the Henri-Michaelis-Menten rate equation for single-substrate enzyme kinetics.

    2012-01-20

    For more than a century the simple single-substrate enzyme kinetics model and related Henri-Michaelis-Menten (HMM) rate equation have been thoroughly explored in various directions. In the present paper we are concerned with a possible generalization of this rate equation recently proposed by F. Kargi (BBRC 382 (2009) 157-159), which is assumed to be valid both in the case that the total substrate or enzyme is in excess and the quasi-steady-state is achieved. We demonstrate that this generalization is grossly inadequate and propose another generalization based on application of the quasi-steady-state condition and conservation equations for both enzyme and substrate. The standard HMM equation is derived by (a) assuming the quasi-steady-state condition, (b) applying the conservation equation only for the enzyme, and (c) assuming that the substrate concentration at quasi-steady-state can be approximated by the total substrate concentration [S](0). In our formula the rate is already expressed through [S](0), and we only assume that when quasi-steady-state is achieved the amount of product formed is negligible compared to [S](0). Numerical simulations show that our formula is generally more accurate than the HMM formula and also can provide a good approximation when the enzyme is in excess, which is not the case for the HMM formula. We show that the HMM formula can be derived from our expression by further assuming that the total enzyme concentration is negligible compared to [S](0).

    The Henry's law constants (KH) of triethylamine (TEA) in pure water and in 1-octanol were measured for the temperatures pertinent to the lower troposphere (278-298 K) using a bubble column system coupled to a Fourier transform infrared spectrometer. The KH values of TEA in water and 1-octanol at 298 K are 5.75 ± 0.86 mol L-1 atm-1 and 115.62 ± 5.78 mol L-1 atm-1. The KH values display strong dependence on temperature, pH, and ionic strength. The characteristic times for TEA to establish an equilibrium between gas and droplet with a size of 5.6 µm are ~33 s (298 K, pH = 5.6); ~8.9 × 102 s (278 K, pH = 5.6); ~1.3 × 103 s (298 K, pH = 4.0); and 3.6 × 104 s (278 K, pH = 4.0). The evaluation of TEA partitioning between gas phase and condensed phase implies that TEA predominantly resides in rainwater, and TEA loss to organic aerosol is negligible.

    Two general types of sand and gravel occur in McHenry County - unconfined aquifers, which are at or near the land surface, and semiconfined aquifers, which are overlain by one or more till members. Water levels in both types of aquifers are mapped from measurements made in the spring of 1979. The water-level configuration roughly parallels the land surface. Moraines and other topographically high features coincide with ground-water divides of local flow systems. Flow paths from divides to low-lands are relatively short - a few miles or less. Recharge predominates in uplands, whereas discharge predominates in lowlands. Water levels change seasonally in response to variations in recharge and discharge conditions. The highest water levels occur during spring and decline during the rest of the year. Ground water is of the calcium magnesium bicarbonate type and is of acceptable quality for most uses. However, for domestic and some industrial uses, treatment may be required to reduce hardness and to remove iron. Hardness ranged from 130 to 600 milligrams per liter as calcium carbonate, and dissolved iron concentrations ranges from less than 10 to 6200 micrograms per liter. The specific conductance of ground water ranged from 260 to 1170 micromhos per centimeter. Specific conductance exceeded 1000 micromhos per centimeter near Huntley and Hebron. Nitrate concentration was generally less than 0.68 milligrams per liter. 22 refs., 9 figs., 3 tabs.

    Adolescence is a lonely time for all of us, as we shift our emotional attachment from our parents to our own autonomous selves and to those people outside our families who will be essential to our emotional growth. Perhaps because Henry James's novel The Ambassadors (1903) deals so masterfully with this subject, it promised the author that there would be a future beyond her senior year in college. The novel has two protagonists: a young American who has arrived at his maturity in Paris, and a middle-aged man who lives in a gray, ungratifying world because he has missed the opportunity to complete his unfolding into an independent sexual being. For background material, James called upon two periods from his own life: his unhappy adolescence, which he overcame by making a life for himself as a writer in England, and his continuing emotional growth at the time he wrote the novel, at the age of 56. The author deals with both adolescence itself and with the ways in which we use the coping skills and creative strengths we developed in adolescence to enrich our lives and sustain ourselves at times of crisis.

    The growth of biomedical engineering at The Henry Samueli School of Engineering at the University of California, Irvine (UCI) has been rapid since the Center for Biomedical Engineering was first formed in 1998 [and was later renamed as the Department of Biomedical Engineering (BME) in 2002]. Our current mission statement, “Inspiring Engineering Minds to Advance Human Health,” serves as a reminder of why we exist, what we do, and the core principles that we value and by which we abide. BME exists to advance the state of human health via engineering innovation and practices. To attain our goal, we are empowering our faculty to inspire and mobilize our students to address health problems. We treasure the human being, particularly the human mind and health. We believe that BME is where minds are nurtured, challenged, and disciplined, and it is also where the health of the human is held as a core mission value that deserves our utmost priority (Figure 1). Advancing human health is not a theoretical practice; it requires bridging between disciplines (engineering and medicine) and between communities (academic and industry).

    This meeting of the Committee on the History of Science and Epistemology takes place as we celebrate the 250th anniversary of the creation of the world's first veterinary schools, a major event among all those that, in the wake of the Physiocrat movement initiated by Quesnay and DuPont de Nemours, shaped the modernisation of agriculture in France during the 18th century. Henri-Léonard Bertin (1720-1792) was the impetus to the restructuring process. He was well aware that farming should not remain an activity that solely provides a livelihood for the population, but that it needed to be modernised, i.e. it should produce more, and better. His view was that agriculture could become a great source of riches for France and therefore, a true economic and even political force. He used the various official positions he occupied during that period (Intendant of Lyon (1754-1757), Controller General of Finances (1759-1763), Minister-Secretary of State for Agriculture (1763-1780) to initiate a number of reforms that brought about the modernisation of the kingdom's agricultural world.

    Walter Henry Anderson, a brewer's clerk in Burton-upon-Trent, became a missionary doctor, supported by a society promoting welfare and evangelism in Jewish communities abroad. His family background was rich in pastoral ministry at home and adventure abroad. Arguably, this background played a part in his decision to serve the Jews of Safed. His life in Palestine entailed much enterprise and hardship as he raised a family, fought disease and set up a mission hospital serving not only the Jewish community but persons of all faiths. His years in Palestine, from 1894 to 1915, were times of peace in the Middle East before the turmoil unleashed by the Great War. Jews from the Diaspora were gaining an increasing foothold in Palestine, their 'Promised Land'. Themes of that era - the rise of Zionism, confrontation between Judaism and evangelical Christianity, conflict between immigrant Jew and Palestinian Arab and the remarkable travels of Lawrence of Arabia were interwoven with the lives of Dr Anderson and his family.

    2003-08-01

    Various models are available for the prediction of Henry's law constant (H) or the air-water partition coefficient (Kaw), its dimensionless counterpart. Incremental methods are based on structural features such as atom types, bond types, and local structural environments; other regression models employ physicochemical properties, structural descriptors such as connectivity indices, and descriptors reflecting the electronic structure. There are also methods to calculate H from the ratio of vapor pressure (p(v)) and water solubility (S(w)) that in turn can be estimated from molecular structure, and quantum chemical continuum-solvation models to predict H via the solvation-free energy (deltaG(s)). This review is confined to methods that calculate H from molecular structure without experimental information and covers more than 40 methods published in the last 26 years. For a subset of eight incremental methods and four continuum-solvation models, a comparative analysis of their prediction performance is made using a test set of 700 compounds that includes a significant number of more complex and drug-like chemical structures. The results reveal substantial differences in the application range as well as in the prediction capability, a general decrease in prediction performance with decreasing H, and surprisingly large individual prediction errors, which are particularly striking for some quantum chemical schemes. The overall best-performing method appears to be the bond contribution method as implemented in the HENRYWIN software package, yielding a predictive squared correlation coefficient (q2) of 0.87 and a standard error of 1.03 log units for the test set.

    Hydrogen peroxide is not only an important oxidant in itself; it also serves as both sink and temporary reservoir for other important oxidants including HOx (OH and HO2) radicals and O3 in the atmosphere. Its partitioning between gas and aqueous phases in the atmosphere, usually described by its Henry's law constant (K(H)), significantly influences its role in atmospheric processes. Large discrepancies between the K(H) values reported in previous work, however, have created uncertainty for atmospheric modelers. Based on our newly developed online instrumentation, we have re-determined the temperature and acidity dependence of K(H) for hydrogen peroxide at an air pressure of (0.960 +/- 0.013) atm (1 atm = 1.01325 x 10(5) Pa). The results indicated that the temperature dependence of K(H) for hydrogen peroxide fits to the Van't Hoff equation form, expressed as lnK(H) = a/T - b, and a = -deltaH/R, where K(H) is in M/atm (M is mol/L), T is in degrees Kelvin, R is the ideal gas constant, and deltaH is the standard heat of solution. For acidity dependence, results demonstrated that the K(H) value of hydrogen peroxide appeared to have no obvious dependence on decreasing pH level (from pH 7 to pH 1). Combining the dependence of both temperature and acidity, the obtained a and b were 7024 +/- 138 and 11.97 +/- 0.48, respectively, deltaH was (58.40 +/- 1.15) kJ/(K x mol), and the uncertainties represent sigma. Our determined K(H) values for hydrogen peroxide will therefore be of great use in atmospheric models.

  8. Flexure and faulting of sedimentary host rocks during growth of igneous domes, Henry Mountains, Utah

    A sequence of sedimentary rocks about 4 km thick was bent, stretched and uplifted during the growth of three igneous domes in the southern Henry Mountains. Mount Holmes, Mount Ellsworth and Mount Hillers are all about 12 km in diameter, but the amplitudes of their domes are about 1.2, 1.85 and 3.0 km, respectively. These mountains record successive stages in the inflation of near-surface diorite intrusions that are probably laccolithic in origin. The host rocks deformed along networks of outcrop-scale faults, or deformation bands, marked by crushed grains, consolidation of the porous sandstone and small displacements of sedimentary beds. Zones of deformation bands oriented parallel to the beds and formation contacts subdivided the overburden into thin mechanical layers that slipped over one another during doming. Measurements of outcrop-scale fault populations at the three mountains reveal a network of faults that strikes at high angles to sedimentary beds which themselves strike tangentially about the domes. These faults have normal and reverse components of slip that accommodated bending and stretching strains within the strata. An early stage of this deformation is displayed at Mount Holmes, where states of stress computed from three fault samples correlate with the theoretical distribution of stresses resulting from bending of thin, circular, elastic plates. Field observations and analysis of frictional driving stresses acting on horizontal planes above an opening-mode dislocation, as well as the paleostress analysis of faulting, indicate that bedding-plane slip and layer flexure were important components of the early deformation. As the amplitude of doming increased, radial and circumferential stretching of the strata and rotation of the older faults in the steepening limbs of the domes increased the complexity of the fault patterns. Steeply-dipping, map-scale faults with dip-slip displacements indicate a late-stage jostling of major blocks over the central

    Bicyclo[3.2.1]octan-8-ones have been prepared from a tandem Michael-Henry reaction between cyclohexane-1,2-diones and nitroalkenes using a quinine-derived thiourea as the catalyst. Although four stereogenic centers were created during the reaction, only two diastereomers were obtained in good diastereoselectivity and high enantioselectivity (92-99% ee). When 3-methylcyclohexane-1,2-dione (R1 = Me) was used as the substrate, only the regioisomeric product of the corresponding thermodynamic enolate was obtained. PMID:20532185

    In 2001, the U.S. Surgeon General declared publicly that culture counts in mental health care. This welcome recognition of the role of culture in mental health appears somewhat belated. In 1956, Frantz Fanon and Henri Collomb both presented culturally sensitive studies of the Thematic Apperception Test at the major French-language mental health conference. The contrast between these two studies and between the careers of Fanon and Collomb reveals some of the difficulties in creating cultural and gender sensitivity in psychiatry or psychology.

    Surface displacements resulting from upper-crustal intrusions are a paramount concern for communities and facilities located near active volcanic areas (e.g. Campi Flegrei, Yucca Mtn.). Study of active intrusions is limited to remote observations through geophysical/geodetic methods. While surface displacements due to intrusions can be measured easily, intrusion shapes and depths are often based on simplified assumptions (e.g. spheres and ellipsoids). These models benefit from data constraining both the geometries of the individual intrusions, and the kinematics and mechanics of deformation within the overlying strata. Mount Ellsworth, a sub-volcanic intrusion within the Henry Mtns., is an ideal natural laboratory for the study of near surface intrusions because it was emplaced into relatively flat-lying stratigraphy ~24 Ma when the stress field was largely isotropic. Previous studies of Mt. Ellsworth (i.e. Hunt, 1953; Jackson and Pollard, 1988) present competing emplacement models (e.g. single vs. multiple batch construction) based on slightly different geologic maps. Through a combination of 1:5000 scale field mapping and profile-oriented gravity study, we have produced new detailed geologic maps and cross sections of Mt. Ellsworth. These were intended to be used to test emplacement models. However, the results suggest that the initial goals set out for this study could not be realized due to the lack of exposed intrusion, the relatively small dimensions of the exposed sills, and the largely uncapped nature of the mountain. Mapping results demonstrate, however, that some of the assumptions of the models theorized by previous researchers were inappropriately applied to Mt. Ellsworth. These assumptions include the thickness and separation of stratigraphic units, the size and distribution of sills and smaller intrusions, structural attitudes of beds and sills, and the presence of exposure of the main body of the intrusion.

    This talk is about an interaction between two 18th-century natural philosophers (physical scientists), Henry Cavendish and John Michell, and its most important outcome, the experiment of weighing the world (their name for it) using a torsion balance (our name for it). Michell was the most inventive of the 18th century English natural philosophers, and Cavendish was the first of his countrymen to possess abilities at all comparable with Newton's. By their interests and skills, they were drawn to one another. Both were universal natural philosophers, equally adept at building scientific instruments, performing experiments, constructing theory, and using mathematics; both had a penchant for exacting, quantitative work. Both also had fitful habits of publication, which did not begin to reveal the range of their work, to the mystification of later scientists and historians. Late in life, Cavendish and Michell turned their attention to the force that Newton had examined most completely, a singular triumph of his natural philosophy, the force of universal gravitation. Over the course of the 18th century, abundant evidence of attraction had been gathered from the motions of the earth, moon, planets, and comets, phenomena which span the intermediate range of masses, sizes, and distances. But in three domains of experience, involving the extreme upper and lower limits of masses and dimensions, the universality of gravitation remained an article of faith. These were the gravity of the ``fixed'' stars, the mutual attraction of terrestrial bodies, and the gravitation of light and other special substances. Michell took on himself the task of deducing observable consequences from each of these prospective instances of universal gravitation. Cavendish encouraged Michell, and he followed up the resulting observational and experimental questions. The experiment of weighing the world was the last experiment Mitchell planned and the last experiment Cavendish published. The capstone of

    Evidence for the alteration of the yellow paints in Henri Matisse's Le Bonheur de vivre (1905-1906, The Barnes Foundation) has been observed since the 1990s. The changes in this iconic work of Matisse's Fauvist period include lightening, darkening, and flaking of the yellow paints. Handheld X-ray fluorescence (XRF) and multispectral imaging surveys reveal that the degradation is confined to cadmium yellow (CdS) paints. The discoloration of cadmium yellow paints in Impressionist, Post-Impressionist and early modernist work from the 1880s through the 1920s has been ascribed to the photo-oxidative degradation of CdS. Preliminary investigations of the degraded yellow paints in this work involved Cd LIII-edge X-ray Absorption Near Edge Spectroscopy (XANES) at the Stanford Synchrotron Radiation Light Source (SSRL Menlo Park, California) and Scanning Electron Microscopy-energy dispersive X-ray analysis (SEM-EDS) at the Winterthur Museum Scientific Research and Analysis Laboratory. To determine if the visual changes in the paints did in fact indicate photo-oxidative degradation and if different chemistries could be observed for the lightened versus darkened regions, synchrotron radiation-micro Fourier Transform InfraRed (SR-μFTIR) spectroscopy, X-ray Fluorescence (SR-μXRF) mapping and micro X-ray Absorption Near Edge Spectroscopy (μXANES) mapping at the Cd LIII-edge of the altered paint cross-sections were carried out at the European synchrotron radiation facility (ESRF, Grenoble, France) beamline ID-21. The goal is to elucidate the discoloration mechanisms observed in the paint using elemental and speciation mapping. The μXANES mapping and SR-FTIR imaging showed a substantial enrichment of CdCO3 in the off-white surface crust of the faded/discolored CdS paint. This suggests that the CdCO3 is present as an insoluble photodegradation product rather than solely a paint filler or starting reagent. Additionally, oxalates and sulfates were found to be concentrated at the

    To meet water quality targets and the municipal and industrial water needs of a growing population in the Tualatin River Basin in northwestern Oregon, an expansion of Henry Hagg Lake is under consideration. Hagg Lake is the basin's primary storage reservoir and provides water during western Oregon's typically dry summers. Potential modifications include raising the dam height by 6.1 meters (20 feet), 7.6 meters (25 feet), or 12.2 meters (40 feet); installing additional outlets (possibly including a selective withdrawal tower); and adding additional inflows to provide greater reliability of filling the enlarged reservoir. One method of providing additional inflows is to route water from the upper Tualatin River through a tunnel and into Sain Creek, a tributary to the lake. Another option is to pump water from the Tualatin River (downstream of the lake) uphill and into the reservoir during the winter--the 'pump-back' option. A calibrated CE-QUAL-W2 model of Henry Hagg Lake's hydrodynamics, temperature, and water quality was used to examine the effect of these proposed changes on water quality in the lake and downstream. Most model scenarios were run with the calibrated model for 2002, a typical water year; a few scenarios were run for 2001, a drought year. More...

    Henry Darcy was a civil engineer recognized for a number of technical achievements and scientific discoveries. The sand column experiments for which he is known revealed the linear relationship that exists between fluid motion and driving forces at low velocities. Freeze and Back (1983) stated, ''The experiments carried out by Darcy with the help of his assistant, Ritter, in Dijon, France in 1855 and 1856 represent the beginning of groundwater hydrology as a quantitative science." Because of the prominence given to this experiment, two important facts behind Darcy's contributions to subsurface hydrology have not received much attention. First, Darcy was not only a good engineer, but he was also a highly respected scientist whose knowledge of both the fundamentals of fluid mechanics and the natural world of geology led to better conceptualizing and quantifying of groundwater processes at relevant scales to solve practical problems. The experiments for which he is known may have already been conceived, based on his theoretical understanding, and the results were anticipated (Brown 2002). Second, Darcy, through his contributions with Dupuit, showed that they understood hydrologeology at a regional scale and developed methods for quantification at the scale of geologic stratum (Ritz and Bobek, 2008). The primary thesis of this talk is that scientific contributions such as the one Darcy made require appreciation and a thorough understanding of fundamental theory coupled with observation and recording of phenomena both in nature and in the laboratory. Along with all of the significant theoretical, mathematical modeling, and computational advances we have made in the last several decades, laboratory experiments designed to observe phenomena and processes for better insight, accurate data generation, and hypothesis development are critically important to make scientific and engineering advances to address some of the emerging and societally important problems in hydrology

  17. From the "metaphysics of the individual" to the critique of society: on the practical significance of Michel Henry's phenomenology of life.

    PubMed

    Staudigl, Michael

    This essay explores the practical significance of Michel Henry's "material phenomenology." Commencing with an exposition of his most basic philosophical intuition, i.e., his insight that transcendental affectivity is the primordial mode of revelation of our selfhood, the essay then brings to light how this intuition also establishes our relation to both the world and others. Animated by a radical form of the phenomenological reduction, Henry's material phenomenology brackets the exterior world in a bid to reach the concrete interior transcendental experience at the base of all exteriority. The essay argues that this "counter reduction," designed as a practical orientation to the world, suspends all traditional parameters of onto(theo)logical individuation in order to rethink subjectivity in terms of its transcendental corporeality, i.e., in terms of the invisible display of "affective flesh." The development of this "metaphysics of the individual" anchors his "practical philosophy" as he developed it-under shifting accents-throughout his oeuvre. In particular, the essay brings into focus Henry's reflections on modernity, the industry of mass culture and their "barbaric" movements. The essay briefly puts these cultural and political areas of Henry's of thinking into contact with his late "theological turn," i.e., his Christological account of Life and the (inter)subjective self-realization to which it gives rise.

  1. Comparative study of the dynamic gravimetric and pulse chromatographic methods for the determination of Henry constants of adsorption for VOC zeolite systems

    Nokerman, J.; Canet, X.; Mougin, P.; Limborg-Noetinger, S.; Frère, M.

    2005-09-01

    In this paper, we propose a comparative study between a gravimetric apparatus operating under dynamic conditions and a pulse chromatographic device developed for the determination of Henry constants of adsorption for VOC-zeolite systems. In both cases, we provide a description of the experimental set-up and procedure, as well as a complete report on the treatment of the rough experimental data. The experimental errors are also discussed. The comparison work is based on the study of the adsorption of toluene on a NaY zeolite (Si/Al 2.43) for temperatures ranging from 503 to 623 K. The maximal discrepancy found between the experimental Henry constants was 15.0%. The pulse chromatographic method is only dedicated to high-temperature measurements. For low-temperature experiments, the rough data cannot be treated in an efficient way, and it is not possible to obtain reliable Henry constant values. The dynamic gravimetric method is not temperature limited. It is however time-consuming, especially when low-temperature measurements (not presented in this paper) are concerned. Both methods are complementary if the determination of Henry constants is required in a wide temperature range.

    A straightforward synthesis of mesogenic pyrazoles starting from benzaldehydes by a combination of efficient Henry and Michael reactions led to novel supramolecular liquid crystals. The mesogens are fluorescent 3,5-dimethyl-4-(di or trialkoxyphenyl)pyrazoles and, in spite of the tapered shape of these molecules and their structural simplicity (only one phenyl ring), columnar liquid-crystal phases were formed that are stable at room temperature. The self-assembled structure was studied by XRD and the columnar cross section contains two molecules on average with an antiparallel arrangement of pyrazoles interacting through hydrogen bonds. In contrast, the single-crystal structure of a trimethoxy analog did not show hydrogen-bonded pyrazoles but chains of head-to-tail arranged molecules.

    This report presents the results of the preliminary assessment (PA) conducted by Argonne National Laboratory at a Montana Army National Guard (MTARNG) property near Helena, Montana. Preliminary assessments of federal facilities are being conducted to compile the information necessary for completing preremedial activities and to provide a basis for establishing corrective actions in response to releases of hazardous substances. The principal objective of the PA is to characterize the site accurately and determine the need for further action by examining site activities, quantities of hazardous substances present, and potential pathways by which contamination could affect public health and the environment. This PA satisfies, for the Fort William Henry Harrison property, requirements of the Department of Defense Installation Restoration Program.

    PubMed

    Cook, G C

    2002-06-01

    The "pavilion plan" for hospital design originated in France in the 18th century and was popularised in England by John Roberton and George Godwin in the mid-19th century; the underlying rationale was that with improved ventilation the mortality rate (at that time exceedingly high) was significantly reduced. Among the enthusiasts for this new style was Florence Nightingale (herself a miasmatist)--who had experienced astronomically high death rates in the hospital at Scutari during the Crimean War (1854-6). One of the leading exponents of this style of hospital architecture was Henry Currey (1820-1900) whose greatest achievement was undoubtedly the design for the new St Thomas's Hospital on the Lambeth Palace Road.

  6. Aqueous solubility, Henry's law constants and air/water partition coefficients of n-octane and two halogenated octanes.

    New data on the aqueous solubility of n-octane, 1-chlorooctane and 1-bromooctane are reported between 1 degree C and 45 degrees C. Henry's law constants, K(H), and air/water partition coefficients, K(AW), were calculated by associating the measured solubility values to vapor pressures taken from literature. The mole fraction aqueous solubility varies between (1.13-1.60)x10(-7) for n-octane with a minimum at approximately 23 degrees C, (3.99-5.07)x10(-7) for 1-chlorooctane increasing monotonically with temperature and (1.60-3.44)x10(-7) for 1-bromooctane with a minimum near 18 degrees C. The calculated air-water partition coefficients increase with temperature and are two orders of magnitude lower for the halogenated derivatives compared to octane. The precision of the results, taken as the average absolute deviations of the aqueous solubility, the Henry's law constants, or the air/water partition coefficients, from appropriate smoothing equations as a function of temperature is of 3% for n-octane and of 2% and 4% for 1-chlorooctane and 1-bromooctane, respectively. A new apparatus based on the dynamic saturation column method was used for the solubility measurements. Test measurements with n-octane indicated the capability of measuring solubilities between 10(-6) and 10(-10) in mole fraction, with an estimated accuracy better than +/-10%. A thorough thermodynamic analysis of converting measured data to air/water partition coefficients is presented.

    Despite the clinical importance of ruminal acidosis, ruminal buffering continues to be poorly understood. In particular, the constants for the dissociation of H2CO3 and the solubility of CO2 (Henry's constant) have never been stringently determined for ruminal fluid. The pH was measured in parallel directly in the rumen and the reticulum in vivo, and in samples obtained via aspiration from 10 fistulated cows on hay- or concentrate-based diets. The equilibrium constants of the bicarbonate system were measured at 38°C both using the Astrup technique and a newly developed method with titration at 2 levels of partial pressure of CO2 (pCO2; 4.75 and 94.98 kPa), yielding mean values of 0.234 ± 0.005 mmol ∙ L(-1) ∙ kPa(-1) and 6.11 ± 0.02 for Henry's constant and the dissociation constant, respectively (n/n = 31/10). Both reticular pH and the pH of samples measured after removal were more alkalic than those measured in vivo in the rumen (by ΔpH = 0.87 ± 0.04 and 0.26 ± 0.04). The amount of acid or base required to shift the pH of ruminal samples to 6.4 or 5.8 (base excess) differed between the 2 feeding groups. Experimental results are compared with the mathematical predictions of an open 2-buffer Henderson-Hasselbalch equilibrium model. Because pCO2 has pronounced effects on ruminal pH and can decrease rapidly in samples removed from the rumen, introduction of a generally accepted protocol for determining the acid-base status of ruminal fluid with standard levels of pCO2 and measurement of base excess in addition to pH should be considered.

    Craters around the Schiaparelli Basin (sim460 km diameter; 2.71^circS 16.77^circE) on Mars are distributed in a unique combination that includes infilled craters with mound on their floors. The mounds have preserved intriguing layers in stratigraphy that has exposed pristine sets of geomorphic and geochemical signatures bearing strong implications towards understanding geological history of Mars. With a view to avail the maximum scientific benefit from this unique geological assemblage on Mars, we have carried out remote analysis of stratigraphy of layers exposed over Henry crater's (sim150 km diameter; 10.79^circN 23.45^circE) mound (rising sim2km from floor) to infer the origin and episodes of geological events occurred in the region. Henry crater is situated approximately 500 km northeast of Schiaparelli Basin. Using crater counting technique the age of the topmost surface of the crater mound is found to be sim3.64 Ga since the exposure of this strata post complete infilling. The stratigraphy of consistent and conformable layers in the crater interior acts as a proxy of the long-lived event of sediment deposition in a rather quiescent condition. Distinct layering can be traced across the crater from the mound to the crater wall across the floor. Evidence for differential erosion of deposited materials, wherein local geological setup developed in the different parts of the crater interior is preserved. Using MRO HiRISE & CTX images, distinct spatial distribution of morphological features distributed in stratigraphy is observed that reveals the dominant geological agents behind their formation, viz. temporal hydrological and eolian processes. The morphological features were aided with an understanding of the composition of the exposed sedimentary succession. MRO CRISM based mineralogical investigation reveals diagnostic signature of the hydrated sulfate mineral Kieserite. Based on the thermodynamic properties of Kieserite and apparent lack of desiccation cracks in

    An experimental investigation of Ce, Sm and Tm rare earth element (REE) partition coefficients between coexisting garnets (both natural and synthetic) and hydrous liquids shows that Henry's Law may not be obeyed over a range of REE concentrations of geological relevance. Systematic differences between the three REE and the two garnet compositions may be explained in terms of the differences between REE ionic radii and those of the dodecahedral site into which they substitute, substantiating the Harrison and Wood (1980) model of altervalent substitution. Model calculations demonstrate that significant variation can occur in the rare earth contents of melts produced from a garnet lherzolite, if Henry's Law partition coefficients do not apply for the garnet phase.

    The influence of seawater salts as salting out agents on the purge-and-trap gas chromatography (PT-GC) determination of trihalomethanes (THMs) was studied. This is particularly important since seawater is chlorinated when used as a cooling agent in coastal nuclear power stations. The chlorination produces unwanted THMs as by-products. A PT-GC apparatus was used to determine the Henry's Law constant of each THM, with seawater as the sample matrix.

    Sulfides are known for their strong odor impact even at very low concentrations. Here, we report Henry's law constants (HLCs) measured at the nanomolar concentration range in water for monosulfides (dimethylsulfide, ethylmethylsulfide, diethylsulfide, allylmethylsulfide) and disulfides (dimethyldisulfide, diethylsulfide, dipropylsulfide) using a dynamic stripping technique coupled to Proton Transfer Reaction-Mass Spectrometry (PTR-MS). The experimental data were compared with literature values and to vapor/solubility calculations and their consistency was confirmed employing the extra-thermodynamic enthalpy-entropy compensation effect. Our experimental data are compatible with reported literature values, and they are typically lower than averaged experimental literature values by about 10%. Critical comparison with other freely available models (modeled vapor/solubility; group and bond additivity methods; Linear Solvation Energy Relationship; SPARC) was performed to validate their applicability to monosulfides and disulfides. Evaluation of theoretical models reveals a large deviation from our measured values by up to four times (in units of Matm(-1)). Two group contribution models were adjusted in view of the new data, and HLCs for a list of sulfur compounds were calculated. Based on our findings we recommend the evaluation and adaption of theoretical models for monosulfides and disulfides to lower values of solubility and higher values of fugacity.

    In the late nineteenth and early twentieth centuries, a number of European expeditions traveled to the region of Lake Rudolf, now largely in northern Kenya. Although diverse in intent, many of these were undertaken in the interests of furthering colonial territorial claims. In 1900-1901, Major Herbert Henry Austin led a British expedition down to the lake from Khartoum in the north. Of the 62 African, Arab, and European members of this expedition, only 18 (29 %) arrived at its final destination at Lake Baringo in Kenya. Because of a confluence of adverse climatic, social, and political conditions, the expedition ran short of food supplies when it arrived at the northern end of the lake in April 1901. For the next 4 months, the members of the expedition struggled down the west side of the lake and beyond. The greatest mortality (91 %) occurred among the 32 African transport drivers who were the most marginally nourished at the outset of the trip. The lowest mortality among the Africans on the expedition (15 %) occurred among the members of the Tenth Sudanese Rifles Battalion, who had an excellent nutritional status at the start of the expedition. Major Austin himself suffered from severe scurvy with retinal hemorrhages which left him partially blind in his right eye. An analysis of the mortality rates among the groups that participated in this expedition was undertaken. This revealed that poor nutritional status at the start of the trip was predictive of death from starvation.

    Hybrid quantum mechanics and molecular mechanics (QM/MM) computer simulations have become an indispensable tool for studying chemical and biological phenomena for systems too large to treat with quantum mechanics alone. For several decades, semi-empirical QM methods have been used in QM/MM simulations. However, with increased computational resources, the introduction of ab initio and density function methods into on-the-fly QM/MM simulations is being increasingly preferred. This adaptation can be accomplished with a program interface that tethers independent QM and MM software packages. This report introduces such an interface for the BOSS and Gaussian programs, featuring modification of BOSS to request QM energies and partial atomic charges from Gaussian. A customizable C-shell linker script facilitates the inter-program communication. The BOSS–Gaussian interface also provides convenient access to Charge Model 5 (CM5) partial atomic charges for multiple purposes including QM/MM studies of reactions. In this report, the BOSS–Gaussian interface is applied to a nitroaldol (Henry) reaction and two methyl transfer reactions in aqueous solution. Improved agreement with experiment is found by determining free-energy surfaces with MP2/CM5 QM/MM simulations than previously reported investigations employing semiempirical methods. PMID:26311531

    Biogenically produced reduced sulfur compounds, including dimethylsulfide (DMS, CH3SCH3), hydrogen sulfide (H2S), carbon disulfide (CS2), methyl mercaptan (CH3SH), and carbonyl sulfide (OCS), are a major source of sulfur in the marine atmosphere. This source is estimated to contribute 25-40% of global sulfur emissions. These species and their oxidation products, dimethyl sulfoxide (DMSO), dimethyl sulfone (DMSO2), and methane sulfonic acid (MSA), dominate the production of aerosol and cloud condensation nuclei (CCN) in the clean marine atmosphere. The multiphase chemical processes for these species must be understood in order to study the evolving role of combustion-produced sulfur oxides over the oceans. Using a newly developed bubble column apparatus, a series of aqueous phase uptake studies have been completed for the reduced sulfur species DMS, H2S, CS2, CH3SH, and OCS. Aqueous phase uptake has been studied as a function of temperature (278-298 K), pH (1-14), H2O2 concentration (0-1 M), NaCl concentration (0-5 M), and (NH4)2SO4 concentration (0-4 M). The Henry's law coefficients for CH3SH and CS2 were determined for the first time, as were the Setchenow coefficients for all the species studied.

    The Henry's law constant (HLC) and the overall mass transfer coefficient are both important parameters for modeling formaldehyde emissions from aqueous solutions. In this work, the apparent HLCs for formaldehyde aqueous solutions were determined in the concentration range from 0.01% to 1% (w/w) and at different temperatures (23, 40, and 55 °C) by a static headspace extraction method. The aqueous solutions tested included formaldehyde in water, formaldehyde-water with nonionic surfactant Tergitol NP-9, and formaldehyde-water with anionic surfactant sodium dodecyl sulfate. Overall, the measured HLCs ranged from 8.33 × 10(-6) to 1.12 × 10(-4) (gas-concentration/aqueous-concentration, dimensionless). Fourteen small-chamber tests were conducted with formaldehyde solutions in small pools. By applying the measured HLCs, the formaldehyde overall liquid-phase mass transfer coefficients (KOLs) were determined to be in the range of 8.12 × 10(-5) to 2.30 × 10(-4) m/h, and the overall gas-phase mass transfer coefficients were between 2.84 and 13.4 m/h. The influences of the formaldehyde concentration, temperature, agitation rate, and surfactant on HLC and KOL were investigated. This study provides useful data to support source modeling for indoor formaldehyde originating from the use of household products that contain formaldehyde-releasing biocides.

  19. On the nameless love and infinite sexualities: John Henry Mackay, Magnus Hirschfeld and the origins of the sexual emancipation movement.

    Two prominent representatives of the sexual emancipation movement in Germany, John Henry Mackay (1864-1933) and Magnus Hirschfeld (1868-1935) launched significant attacks on sexual binarism and its combinatories. Although Mackay defended the nameless love against seminal Christian and subsequent secularised misconstructions of its nature, he was unable to overcome the fundamental scheme of binomic sexuality. Hirschfeld, however, resolved the theoretical issue through his doctrine of sexual intermediaries (Zwischenstufenlehre) which purports that-without exception- all human beings are intersexual variants, i.e. unique composites of different proportions of masculinity and femininity. Since these proportions vary from one sexual layer of description to another in the same individual and can alter or be altered in time, it is sensu stricto not possible implies a radical deconstruction of not only binomic sexuality but its supplementation through a third sex. It offers a meta-theoretical framework for rethinking sexual difference beyond the fictional schemes and categorial closures of Western traditions of sexual identity. His assumption of potentially infinite sexualities anticipates some of the basic tenets forwarded by the philosophical and political agendas of queer studies. to postulate discrete sexual categories. Hirschfeld's doctrine.

    Many economically important species of Populus, especially those in sections Aigeiros and Tacamahaca, remain recalcitrant to genetic transformation. In this study, a simple and reliable protocol was developed for the efficient Agrobacterium-mediated transformation of a difficult-to-transform, but commercially viable, hybrid poplar Populus nigra L. x P. maximowiczii A. Henry (NM6). A plant transformation vector designed to express the beta-glucuronidase (GUS) gene was used to detect transformation events at early stages of plant regeneration and to optimize parameters affecting poplar transformation. The use of zeatin riboside in shoot-induction medium, regeneration of shoots via indirect organogenesis, and early selection pressure were the major modifications that drastically improved the efficiency of poplar transformation and minimized the number of untransformed regenerants. Transgenic shoots were routinely obtained 4-10 weeks after co-culture with A. tumefaciens, with a greater than 90% rate of plant recovery. Stable transgene integration, ranging from a single insertion to ten copies per genome, was confirmed by Southern blot analysis. The mean transformation frequency was 36.3% and about two-thirds of the lines had 1-2 transgene copies. Among the explants, petioles and leaves had a higher transformation frequency than did stem segments. Growth characteristics and the morphology of transgenic poplar plants were identical to untransformed controls. These findings will accelerate the development of P. nigra x P. maximowiczii plants with novel traits, and may also be useful to improve transformation procedures for other Populus species.

    Deformation structures in the wall rocks of igneous intrusions emplaced at shallow crustal depths preserve an important record of how space was created for magma in the host rocks. Trachyte Mesa, a small Oligocene age intrusion in the Henry Mountains, Utah, is composed of a series of stacked tabular, sheet-like intrusions emplaced at 3-3.5 km depth into sandstone-dominated sedimentary sequences of late Palaeozoic-Mesozoic age. New structural analysis of the spatial distribution, geometry, kinematics and relative timings of deformation structures in the host rocks of the intrusion has enabled the recognition of distinct pre-, syn-, and late-stage-emplacement deformation phases. Our observations suggest a two-stage growth mechanism for individual sheets where radial growth of a thin sheet was followed by vertical inflation. Dip-slip faults formed during vertical inflation; they are restricted to the tips of individual sheets due to strain localisation, with magma preferentially exploiting these faults, initiating sill (sheet) climbing. The order in which sheets are stacked impacts on the intrusion geometry and associated deformation of wall rocks. Our results offer new insights into the incremental intrusion geometries of shallow-level magmatic bodies and the potential impact of their emplacement on surrounding host rocks.

    Inverse modeling studies employing data collected from the classic Henry seawater intrusion problem give insight into several important aspects of inverse modeling of seawater intrusion problems and effective measurement strategies for estimation of parameters for seawater intrusion. Despite the simplicity of the Henry problem, it embodies the behavior of a typical seawater intrusion situation in a single aquifer. Data collected from the numerical problem solution are employed without added noise in order to focus on the aspects of inverse modeling strategies dictated by the physics of variable-density flow and solute transport during seawater intrusion. Covariances of model parameters that can be estimated are strongly dependent on the physics. The insights gained from this type of analysis may be directly applied to field problems in the presence of data errors, using standard inverse modeling approaches to deal with uncertainty in data. Covariance analysis of the Henry problem indicates that in order to generally reduce variance of parameter estimates, the ideal places to measure pressure are as far away from the coast as possible, at any depth, and the ideal places to measure concentration are near the bottom of the aquifer between the center of the transition zone and its inland fringe. These observations are located in and near high-sensitivity regions of system parameters, which may be identified in a sensitivity analysis with respect to several parameters. However, both the form of error distribution in the observations and the observation weights impact the spatial sensitivity distributions, and different choices for error distributions or weights can result in significantly different regions of high sensitivity. Thus, in order to design effective sampling networks, the error form and weights must be carefully considered. For the Henry problem, permeability and freshwater inflow can be estimated with low estimation variance from only pressure or only

    The Henry's law constant (H) is a crucial variable to investigate the air-water exchange of persistent organic pollutants. H values for 32 polychlorinated naphthalene (PCN) congeners were measured using an inert gas-stripping technique at five temperatures ranging between 5 and 35 °C. H values in deionized water (at 25 °C) varied between 0.28 ± 0.08 Pa m3 mol-1 (PCN-73) and 18.01 ± 0.69 Pa m3 mol-1 (PCN-42). The agreement between the measured and estimated H values from the octanol-water and octanol-air partition coefficients was good (measured/estimated ratio = 1.00 ± 0.41, average ± SD). The calculated phase change enthalpies (ΔHH) were within the interval previously determined for other several semivolatile organic compounds (42.0-106.4 kJ mol-1). Measured H values, paired atmospheric and aqueous concentrations and meteorological variables were also used to reveal the level and direction of air-sea exchange fluxes of PCNs at the coast of Izmir Bay, Turkey. The net PCN air-sea exchange flux varied from -0.55 (volatilization, PCN-24/14) to 2.05 (deposition, PCN-23) ng m-2 day-1. PCN-19, PCN-24/14, PCN-42, and PCN-33/34/37 were mainly volatilized from seawater while the remaining congeners were mainly deposited. The overall number of the cases showing deposition was higher (67.9%) compared to volatilization (21.4%) and near equilibrium (10.7%).

    The first complete translations into English are presented of two articles written by the outstanding French scientist Henri Poincare and submitted by him in 1905 under the common title of {open_quotes}Sur la dynamique de l`electron{close_quotes} to different journals. In the present edition of these articles by H. Poincare, modern notation is used, and the articles are accompanied by comments written by A.A. Logunov. The author of the comments explains the profound physical meaning and essential novelty of the particular points and relationships established by Poincare. Such explanations are often interspersed with quotations from earlier articles by Poincare, thus clearly indicating that the main initial points of the new theory were put forward by the French scientist much before 1905, while certain concepts like `local` time and the arbitrariness of simultaneity were given a clear explanation from the point of view of physical meaning. A.A. Logunov`s book, presenting the works of Poincare on the development of relativity theory, has had quite a high success among specialists interested in the history of physics, and since 1984 it has been published in Russian three times. The present English-language edition is identical to the last 1988 Russian edition, and is dedicated to the 90th anniversary of Poincare`s articles `On the Dynamics of the Electron`. In preparing the English text, fragments were used of the translation of the long article by H.Poincare published in the book by Professor C.W. Kilmister from King`s College in London/Special Theory of Relativity, Pergamon Press, New York, 1970/.

  5. Measuring Uptake Coefficients and Henry's Law Constants of Gas-Phase Species with Models for Secondary Organic Aerosol

    Volatile organic compounds (VOC) are oxidized in the atmosphere and their products contribute to secondary organic aerosol (SOA) formation. These particles have been shown to have effects on visibility, climate, and human health. Current models typically under-predict SOA concentrations from field measurements. Underestimation of these concentrations could be a result of how models treat particle growth. It is often assumed that particles grow via instantaneous thermal equilibrium partitioning between liquid particles and gas-phase species. Recent work has shown that growth may be better represented by irreversible, kinetically limited uptake of gas-phase species onto more viscous, tar-like SOA. However, uptake coefficients for these processes are not known. The goal of this project is to measure uptake coefficients and solubilities for different gases onto models serving as proxies for SOA and determine how they vary based on the chemical composition of the gas and the condensed phase. Experiments were conducted using two approaches: attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectroscopy and a flow system coupled to a mass spectrometer. The ATR crystal was coated with the SOA proxy and the gas-phase species introduced via a custom flow system. Uptake of the gas-phase species was characterized by measuring the intensity of characteristic IR bands as a function of time, from which a Henry's law constant and initial estimate of uptake coefficients could be obtained. Uptake coefficients were also measured in a flow system where the walls of the flow tube were coated with the SOA proxy and gas-phase species introduced via a moveable inlet. Uptake coefficients were derived from the decay in gas-phase species measured by mass spectrometry. The results of this work will establish a structure-interaction relationship for uptake of gases into SOA that can be implemented into regional and global models.

    Acetone is ubiquitous in the troposphere. Several papers have focused in the past on its gas phase reactivity and its impact on tropospheric chemistry. However, acetone is also present in atmospheric water droplets where its behaviour is still relatively unknown. In this work, we present its gas/aqueous phase transfer and its aqueous phase photooxidation. The uptake coefficient of acetone on water droplets was measured between 268 and 281K (γ=0.7 x 10(-2)-1.4 x 10(-2)), using the droplet train technique coupled to a mass spectrometer. The mass accommodation coefficient α (derived from γ) was found in the range (1.0-3.0±0.25) x 10(-2). Henry's law constant of acetone was directly measured between 283 and 298K using a dynamic equilibrium system (H((298K))=(29±5)Matm(-1)), with the Van't Hoff expression lnH(T)=(5100±1100)/T-(13.4±3.9). A recommended value of H was suggested according to comparison with literature. The OH-oxidation of acetone in the aqueous phase was carried out at 298K, under two different pH conditions: at pH=2, and under unbuffered conditions. In both cases, the formation of methylglyoxal, formaldehyde, hydroxyacetone, acetic acid/acetate and formic acid/formate was observed. The formation of small amounts of four hydroperoxides was also detected, and one of them was identified as peroxyacetic acid. A drastic effect of pH was observed on the yields of formaldehyde, one hydroperoxide, and, (to a lesser extent) acetic acid/acetate. Based on the experimental observations, a chemical mechanism of OH-oxidation of acetone in the aqueous phase was proposed and discussed. Atmospheric implications of these findings were finally discussed.

    Phytoextraction of Cd is a growing biotechnology although we currently know few Cd hyperaccumulators, i.e., plant species able to accumulate at least 0.1 mg Cd g(-1) dry weight in aerial organs. Owing their deep root system and high biomass, trees are more and more preferred to herbaceous species for phytoextraction. Assuming that conifers could be relevant models under cold climates, we investigated cadmium tolerance of the hybrid larch Larix × eurolepis Henry (Larix decidua × Larix kaempferi) and the efficiency of this species to store this metal. In vitro grown larches were chosen in order to reduce time of exposure and to more rapidly evaluate their potential efficiency to accumulate Cd. One-month-old plantlets were exposed for 2 and 4 weeks to 250 and 500 μM Cd. Results showed that they tolerated a 4-week exposure to 250 μM Cd, whereas the content of photosynthetic pigment strongly dropped in plantlets growing in the presence of 500 μM Cd. In the presence of 250 μM Cd, shoot growth slightly decreased but photosynthetic pigment and total soluble carbohydrate contents were not modified and no lipid peroxidation was detected. In addition, these plantlets accumulated proline, particularly in shoots (two to three times more than control). In roots, Cd concentration in the intracellular fraction was always higher than in the cell wall fraction contrary to shoots where Cd concentration in the cell wall fraction increased with time and Cd concentration in the medium. In shoots, Cd concentration was lower than in roots with a ratio of 0.2 after 4 weeks of exposure but stayed around 0.2 mg g(-1) dry weight, thus a value higher than the threshold requested for Cd hyperaccumulators. Hybrid larch would thus be a relevant candidate for field test of Cd phytoextraction.

By uncovering the economic and medical contexts of Henry James's Washington Square-set during the infancy of germ theory and the heyday of American obstetrics-this essay exposes a previously unexplored subtextual history of contagion in the text. Although this scientific history seems relegated to the novel's margins, understanding the changing scientific cosmologies and professional organizations in the context of the novel's setting and composition reveals that these tiny infectious particles and their vectors fundamentally shape the plot of the novel.

    Time-of-flight secondary ion mass spectrometry (ToF–SIMS) has recently been shown to be a valuable tool for cultural heritage studies, especially when used in conjunction with established analytical techniques in the field. The ability of ToF–SIMS to simultaneously image inorganic and organic species within a paint cross section at micrometer-level spatial resolution makes it a uniquely qualified analytical technique to aid in further understanding the processes of pigment and binder alteration, as well as pigment–binder interactions. In this study, ToF–SIMS was used to detect and image both molecular and elemental species related to CdS pigment and binding medium alteration on the painting Le Bonheur de vivre (1905–1906, The Barnes Foundation) by Henri Matisse. Three categories of inorganic and organic components were found throughout Le Bonheur de vivre and co-localized in cross-sectional samples using high spatial resolution ToF–SIMS analysis: (1) species relating to the preparation and photo-induced oxidation of CdS yellow pigments (2) varying amounts of long-chain fatty acids present in both the paint and primary ground layer and (3) specific amino acid fragments, possibly relating to the painting’s complex restoration history. ToF–SIMS’s ability to discern both organic and inorganic species via cross-sectional imaging was used to compare samples collected from Le Bonheur de vivre to artificially aged reference paints in an effort to gather mechanistic information relating to alteration processes that have been previously explored using μXANES, SR-μXRF, SEM–EDX, and SR-FTIR. The relatively high sensitivity offered by ToF–SIMS imaging coupled to the high spatial resolution allowed for the positive identification of degradation products (such as cadmium oxalate) in specific paint regions that have before been unobserved. The imaging of organic materials has provided an insight into the extent of destruction of the original binding medium

    Henry's Law constants (H) and octanol-air partition coefficients (KOA) for polycyclic aromatic hydrocarbons (PAHs) and selected nitrogen-, oxygen- and sulfur-containing derivatives have been computed using the COSMO-RS method between -5 and 40 °C in 5 °C intervals. The accuracy of the estimation was assessed by comparison of COSMOtherm values with published experimental temperature-dependence data for these and similar PAHs. COSMOtherm log H estimates with temperature-variation for parent PAHs are shown to have a root-mean-square (RMS) error of 0.38 (PAH), based on available validation data. Estimates of O-, N- and S-substituted derivative log H values are found to have RMS errors of 0.30 at 25 °C. Log KOA estimates with temperature variation from COSMOtherm are shown to be strongly correlated with experimental values for a small set of unsubstituted PAHs, but with a systematic underestimation and associated RMS error of 1.11. Similar RMS error of 1.64 was found for COSMO-RS estimates of a group of critically-evaluated log KOA values at room temperature. Validation demonstrates that COSMOtherm estimates of H and KOA are of sufficient accuracy to be used for property screening and preliminary environmental risk assessment, and perform very well for modeling the influence of temperature on partitioning behavior in the temperature range -5 to 40 °C. Temperature-dependent shifts of up to 2 log units in log H and one log unit for log KOA are predicted for PAH species over the range -5 and 40 °C. Within the family of PAH molecules, COSMO-RS is sufficiently accurate to make it useful as a source of estimates for modeling purposes, following corrections for systematic underestimation of KOA. Average changes in the values for log H and log KOA upon substitution are given for various PAH substituent categories, with the most significant shifts being associated with the ionizing nitro functionality and keto groups.

    Henri Ellenberger (1905-1993) wrote the first French-language synthesis of transcultural psychiatry ("Ethno-psychiatrie") for the French Encyclopédie Médico-Chirurgicale in 1965. His work casts new light on the early development of transcultural psychiatry in relation to scientific communities and networks, particularly on the role of Georges Devereux (1908-1985). The Ellenberger archives offer the possibility of comparing published texts with archival ones to create a more nuanced account of the history of transcultural psychiatry, and notably of the psychological treatment of Native Americans. This paper examines some key moments in the intellectual trajectories of Devereux and Ellenberger, including Devereux's dispute with Ackerknecht, the careers of Devereux and Ellenberger as therapists at the Menninger Foundation (Topeka, Kansas) in the 1950s, and their respective positions in the research network developed by McGill University (Montreal, Quebec) with the newsletter Transcultural Research in Mental Health Problems Finally, I consider their ties to other important figures in this field as it transitioned from colonial medicine to academic medicine, including Roger Bastide (France), Henri Collomb and the Ortigues (France and Africa), as well as Eric Wittkower and Brian Murphy (Canada) and Alexander Leighton (United States and Canada).

    In the fall of 1945, Secretary of Commerce Henry Wallace handpicked Edward Condon, a respected theoretical physicist, to become director of the National Bureau of Standards. Already regarded by many academic and industrial scientists as a second-rate research institution, the Bureau had deteriorated further during the Great Depression. An ardent New Dealer who favored government action to prevent anticompetitive behavior in the marketplace, Wallace claimed that giant corporations leveraged their extensive patent holdings and research capabilities to manipulate markets and restrict competition at the expense of smaller firms without similar resources. Through a revitalized Bureau of Standards, Wallace intended to mitigate monopolistic behavior among large companies by transforming the Department of Commerce into an effective clearinghouse for scientific research that would stimulate technological innovation in small businesses. The Bureau's postwar expansion, however, foundered on congressional efforts to dismantle the legacies of the New Deal, Condon's lack of commitment to the technical requirements of the small business community, and the intense competition for resources within an institutionally pluralist federal research establishment dominated by the exigencies of the Cold War. Without sufficient financial support from congressional appropriations committees, Condon turned to the military to fund new research programs at the Bureau of Standards. These programs, however, owed their institutional growth to the demands of the national security state, not to the fading influence of Henry Wallace's New Deal liberalism.

    An unprecedented organocatalytic enantioselective vinylogous Michael addition/Henry cyclization cascade is presented for the synthesis of highly substituted tetrahydrofluoren-9-ones 3 employing novel 1,3-indandione-derived pronucleophiles 1a-g and nitroalkenes 2. Following a very simple protocol, a wide range of products were obtained in good to excellent yields and with excellent enantioinduction (43-98% yield, up to 98% ee). The reaction proceeded with excellent diastereocontrol despite the simultaneous generation of four stereogenic centers. Surprisingly, when 2-(1-phenylethylidene)-1H-indandione (1h) was used as a pronucleophile, no cyclization was observed, and only Michael addition adducts 4a-x were furnished in very good yields and excellent enantioselectivities.

    Proton-transfer-reaction mass spectrometry (PTR-MS) was used as an analytical tool to measure gas-phase concentrations of short-chain fatty acids. Chemical ionisation of C2C6 carboxylic acids by PTR-MS produced intense protonated molecular ions (with traces of hydrates) along with acylium ion fragments. Gas-phase concentrations were derived using the established method for calculating PTR-MS sensitivity factors. Henry's law constants of carboxylic acids for aqueous solutions at 40 °C were determined. Direct monitoring of volatile fatty acids, known to be associated with secretions from the human axilla, was performed via a specially designed transfer device situated in the axilla. Mass spectral data corresponded with the findings of a sensory assessor.

    Three theories have been proposed to explain the relationship between suicide and economic fluctuations, including the Durkheim (nonlinear), Ginsberg (procyclical), and Henry and Short (countercyclical) theories. This study tested the effect of economic fluctuations, measured by unemployment rate, on suicide rates in Canada from 1926 to 2008. Autoregressive integrated moving average time-series models were used. The results showed a significant relationship between suicide and economic fluctuation; this association was positive during the contraction period (1926-1950) and negative in the period of economic expansion (1951-1973). Males and females showed differential effects in the period of moderate unemployment (1974-2008). In addition, the suicide rate of mid-adults (45-64) was most impacted by economic fluctuations. Our study tends to support Durkheim's theory and suggests the need for public health responses in times of economic contraction and expansion.

    A stereoselective aza-Henry reaction between an arylnitromethane and Boc-protected aryl aldimine using a homogeneous Brønsted acid-base catalyst was translated from batch format to an automated intermittent-flow process. This work demonstrates the advantages of a novel intermittent-flow setup with product crystallization and slow reagent addition which is not amenable to the standard continuous equipment: plug flow tube reactor (PFR) or continuous stirred tank reactor (CSTR). A significant benefit of this strategy was the integration of an organocatalytic enantioselective reaction with straightforward product separation, including recycle of the catalyst, resulting in increased intensity of the process by maintaining high catalyst concentration in the reactor. A continuous campaign confirmed that these conditions could effectively provide high throughput of material using an automated system while maintaining high selectivity, thereby addressing nitroalkane safety and minimizing catalyst usage.

    The chemical and physical alterations of cadmium yellow (CdS) paints in Henri Matisse's The Joy of Life (1905-1906, The Barnes Foundation) have been recognized since 2006, when a survey by portable X-ray fluorescence identified this pigment in all altered regions of the monumental painting. This alteration is visible as fading, discoloration, chalking, flaking, and spalling of several regions of light to medium yellow paint. Since that time, synchrotron radiation-based techniques including elemental and spectroscopic imaging, as well as X-ray scattering have been employed to locate and identify the alteration products observed in this and related works by Henri Matisse. This information is necessary to formulate one or multiple mechanisms for degradation of Matisse's paints from this period, and thus ensure proper environmental conditions for the storage and the display of his works. This paper focuses on 2D full-field X-ray Near Edge Structure imaging, 2D micro-X-ray Diffraction, X-ray Fluorescence, and Fourier Transform Infra-red imaging of the altered paint layers to address one of the long-standing questions about cadmium yellow alteration—the roles of cadmium carbonates and cadmium sulphates found in the altered paint layers. These compounds have often been assumed to be photo-oxidation products, but could also be residual starting reagents from an indirect wet process synthesis of CdS. The data presented here allow identifying and mapping the location of cadmium carbonates, cadmium chlorides, cadmium oxalates, cadmium sulphates, and cadmium sulphides in thin sections of altered cadmium yellow paints from The Joy of Life and Matisse's Flower Piece (1906, The Barnes Foundation). Distribution of various cadmium compounds confirms that cadmium carbonates and sulphates are photo-degradation products in The Joy of Life, whereas in Flower Piece, cadmium carbonates appear to have been a [(partially) unreacted] starting reagent for the yellow paint, a role

  8. Smog chamber experiments to investigate Henry's law constants of glyoxal using different seed aerosols as well as imidazole formation in the presence of ammonia

    Aerosols play an important role in the chemistry and physics of the atmosphere. Hence, they have a direct as well as an indirect impact on the earth's climate. Depending on their formation, one distinguishes between primary and secondary aerosols[1]. Important groups within the secondary aerosols are the secondary organic aerosols (SOAs). In order to improve predictions about these impacts on the earth's climate the existing models need to be optimized, because they still underestimate SOA formation[2]. Glyoxal, the smallest α-dicarbonyl, not only acts as a tracer for SOA formation but also as a direct contributor to SOA. Because glyoxal has such a high vapour pressure, it was common knowledge that it does not take part in gas-particle partitioning and therefore has no impact on direct SOA formation. However, the Henry's law constant for glyoxal is surprisingly high. This has been explained by the hydration of the aldehyde groups, which means that a species with a lower vapour pressure is produced. Therefore the distribution of glyoxal between gas- and particle phase is atmospherically relevant and the direct contribution of glyoxal to SOA can no longer be neglected[3]. Besides this particulate glyoxal is able to undergo heterogeneous chemistry with gaseous ammonia to form imidazoles. This plays an important role for regions with aerosols exhibiting alkaline pH values for example from lifestock or soil dust because imidazoles as nitrogen containing compounds change the optical properties of aerosols[4]. A high salt concentration present in chamber seed aerosols leads to an enhanced glyoxal uptake into the particle. This effect is called "salting-in". The salting effect depends on the composition of the seed aerosol as well as the soluble compound. For very polar compounds, like glyoxal, a "salting-in" is observed[3]. Glyoxal particle formation during a smog chamber campaign at Paul-Scherrer-Institut (PSI) in Switzerland was examined using different seed aerosols

    New data on the vapour pressures and aqueous solubility of 1,8-dichlorooctane and 1,8-dibromooctane are reported as a function of temperature between 20 degrees C and 80 degrees C and 1 degrees C and 40 degrees C, respectively. For the vapour pressures, a static method was used during the measurements which have an estimated uncertainty between 3% and 5%. The aqueous solubilities were determined using a dynamic saturation column method and the values are accurate to within +/-10%. 1,8-Dichlorooctane is more volatile than 1,8-dibromooctane in the temperature range covered (p(sat) varies from 3 to 250 Pa and from 0.53 to 62 Pa, respectively) and is also approximately three times more soluble in water (mole fraction solubilities at 25 degrees C of 5.95 x 10(-7) and 1.92 x 10(-7), respectively). A combination of the two sets of data allowed the calculation of the Henry's law constants and the air water partition coefficients. A simple group contribution concept was used to rationalize the data obtained.

    In 1953, neurosurgeon William Beecher Scoville performed a bilateral mesial temporal lobe resection on patient Henry Molaison, who suffered from epilepsy. The operation was novel as a treatment for epilepsy and had an unexpected consequence: a severe compromise of Molaison's anterograde memory. In a landmark 1957 publication, Scoville and Milner concluded that mesial temporal lobe structures, particularly the hippocampi, were integral to the formation of new, recent memories. Over the next 5 decades, more than 100 researchers studied Molaison's memory, behavior, and learning skills, making him one of the most famous patients in the history of cognitive neuroscience. Following his death in 2008, his brain was scanned in situ and ex vivo and then sectioned into 2401 sections. Histological evaluation of Molaison's brain further elucidated which mesial temporal lobe structures were preserved or resected in his operation, shedding new light on the neuroanatomic underpinnings of short-term memory. Scoville regretted Molaison's surgical outcome and spoke vigorously about the dangers of bilateral mesial temporal lobe surgery. This report is the first historical account of Molaison's case in the neurosurgical literature, serving as a reminder of Molaison's contributions and of the perils of bilateral mesial temporal lobe surgery.

    Novel chiral N-phosphinamide and N-phosphinyl imines have been designed, synthesized and applied to asymmetric aza-Henry reaction to give excellent chemical yields (92%- quant.) and diastereoselectivity (91% to >99%de). The reaction showed a great substrate scope in which aromatic/aliphatic aldehyde- and ketone-derived N-phosphinyl imines can be employed as electrophiles. The chiral N-phosphinamide can be stored at room temperature for more than 2 months without inert gas protection, and chiral N-phosphinyl imines were also proven to be highly stable at room temperature for a long period under inert gas protection. The N-phosphinyl group enabled the product purification to be performed simply by washing crude product with EtOAc and hexane. This reaction joined other eight GAP (Group-Assistant-Purification) chemistry processes that were developed in our laboratories. The absolute configuration has been unambiguously determined by converting a β-nitroamine product into a known N-Boc sample.

    Cardinal John Henry Newman's book, The Idea of a University, first published in the mid nineteenth century, is often invoked as the epitome of the liberal Enlightenment University in discussions and debates about the role and purpose of nurse education. In this article I will examine Newman's book in greater detail and with a more critical eye than is generally the case in the writing of nurse academics. In particular, I will focus on the claims that Newman was a champion of the Enlightenment University of the nineteenth century, that he promoted the idea of 'disinterested' universal knowledge for its own sake, that he was an early advocate of the pursuit of knowledge through scientific research, and the supposition that he would have welcomed the discipline of nursing into the University. In each case, I will suggest that these claims are based on an extremely selective reading of Newman's work. I will conclude by employing the example of practice development to propose an alternative way for nursing to find its place in the modern University that does not involve a retreat into what I will argue is an outdated and nostalgic view of the aims and purpose of higher education.

    Studies to determine the hydrologic conditions in mined and reclaimed mine areas, as well as areas of proposed mining, have become necessary with the enactment of the Surface Mining Control and Reclamation Act of 1977. Honey Creek in Henry County, Missouri, has been re-routed to flow through a series of former strip mining pits which lie within the Honey Creek coal strip mine reclamation site. During intense or long duration rainfalls within the Honey Creek basin, surface runoff has caused flooding on agricultural land near the upstream boundary of the reclamation site. The calculated existing design discharge (3,050 cubic feet per second) water-surface profile is compared to the expected water-surface profiles from three assumed alternative channel modifcations within the Honey Creek study area. The alternative channel modifications used in these analyses include (1) improvement of channel bottom slope, (2) relocation of spoil material, and (3) improved by-pass channel flow conditions. The alternative 1, 2, and 3 design discharge increase will reduce the agricultural field current (1990) frequency of backwater flooding from a 3-year to a 6.5-year event.

    The Fox Chain of Lakes is a glacial lake system in McHenry and Lake Counties in northern Illinois and southern Wisconsin. Sedimentation and nutrient overloading have occurred in the lake system since the first dam was built (1907) in McHenry to raise water levels in the lake system. Using data collected from December 1, 1997, to June 1, 1999, suspended-sediment budgets were constructed for the most upstream lake in the system, Grass Lake, and for the lakes downstream from Grass Lake. A total of 64,900 tons of suspended sediment entered Grass Lake during the study, whereas a total of 70,600 tons of suspended sediment exited the lake, indicating a net scour of 5,700 tons of sediment. A total of 44,100 tons of suspended sediment was measured exiting the Fox Chain of Lakes at Johnsburg, whereas 85,600 tons entered the system downstream from Grass Lake. These suspended-sediment loads indicate a net deposition of 41,500 tons downstream from Grass Lake, which represents a trapping efficiency of 48.5 percent. A large amount of recreational boating takes place on the Fox Chain of Lakes during summer months, and suspended-sediment load was observed to rise from 110 tons per day to 339 tons per day during the 1999 Memorial Day weekend (May 26 ?31, 1999). Presumably, this rise was the result of the boating traffic because no other hydrologic event is known to have occurred that might have caused the rise. This study covers a relatively short period and may not represent the long-term processes of the Fox Chain of Lakes system, although the sediment transport was probably higher than an average year. The bed sediments found on the bottom of the lakes are composed of mainly fine particles in the silt-clay range. The Grass Lake sediments were characterized as black peat with an organic content of between 9 and 18 percent, and the median particle size ranged from 0.000811 to 0.0013976 inches. Other bed material samples were collected at streamflow-gaging stations on the

    Repeat 2008 and 2011 NCALM airborne LiDAR data bracket a large 2010 storm over the Henry Mountains, Utah. This flood caused significant channel erosion and deposition, both of which locally exceeded 2 meters. We compare LiDAR difference maps to surface grain size distributions and channel bed topography to better understand factors that influenced the spatial distributions of elevation changes. Complete river bed topography was resolved over many kilometers because channels were dry when scanned. Systematic variations in grain size distributions among channels were measured by conducting pebble counts. Individual counts consisted of a minimum of 250 measured clasts to allow for robust statistics on coarse grain distributions, with grain sizes ranging from sand to boulders. Bed topography maps and field measurements indicate that channel morphology varies systematically with local grain size distributions and in particular with the abundance of boulders. Reach morphologies range from step-pools to gravel plane-beds along individual channels. We generalize channel topography using various roughness metrics and apply similar metrics to the spatial distribution of topographic changes. Channel width constrictions, common in these canyons, tend to cause net deposition upstream and erosion downstream of these reaches. We also found that areas of erosion and deposition tend to change more abruptly along channels with coarser sediment because immobile grains (often large boulders) act as local base level controls. However, it appears that overall erosion and deposition patterns are not strongly correlated with local channel slope or other characteristics of reach morphology. We interpret this to indicate that before the 2010 flood, channel reaches were already adjusted to local flow conditions in previous floods, through surface grain size sorting and other morphological adjustments. Although erosion and deposition were locally significant from the 2010 flood, most channel

    STUDY OBJECTIVE--Coeur en santé St-Henri is a five year, community based, multifactorial, heart health promotion programme in a low income, low education neighbourhood in Montreal, Canada. The objectives of this programme are to improve heart-healthy behaviours among adults of St-Henri. This paper describes the theoretical model underlying programme development as well as our early field experience implementing interventions. DESIGN--The design of the intervention programme is based on a behaviour change model adapted from social learning theory, the reasoned action model, and the precede-proceed model. The Ottawa charter for health promotion provided the framework for the development of specific interventions. Each intervention is submitted to formative, implementation, and impact evaluations using simple and inexpensive methods. PARTICIPANTS--The target population consists of adults living in St-Henri, a neighbourhood of 23,360 residents. Because of costs constraints, the intervention strategy targets women more specifically. The community is one of the poorest in Canada with 46% of the population living below the poverty line and 20% being very poor. The age-sex adjusted ischaemic heart disease mortality in 1985-87 was 317 per 100,000 compared with 126 per 100,000 in an affluent adjacent neighbourhood. RESULTS--Thirty nine distinct interventions have been developed and tested in the community, eight related to tobacco, 10 to diet, seven to physical activity, and 14 which are multifactorial. The interventions include smoking cessation and healthy recipes contests, a menu labelling and healthy food discount programme in restaurants, a point of choice nutrition education campaign, healthy eating and smoking cessation workshops, a walking club, educational material, print and electronic media campaigns, heart health fairs, and community events. CONCLUSION--An integrated heart health promotion programme is feasible in low income urban neighbourhoods but not all

    In Sudan, modern medical practice and medical research began soon after the creation of Anglo-Egyptian Sudan at the turn of the 20th century. The benevolent involvement of Sir Henry Solomon Wellcome, and the ingenious feat of his protégé Sir Andrew Balfour, was crucial to the strong foundation of that establishment. Sir Henry Wellcome provided the financial sponsorship plus influential, logistical and moral support. Dr Balfour put great energy into making the enterprise one of the most amazing medical achievements in colonial medicine. Improvement in the public health of the capital Khartoum was emulated by other doctors working in this vast country. Research was not restricted to tropical medicine; it also encompassed agricultural and chemical research. This helped with the establishment of the first modern medical school in the country in 1924 and resulted in the medical service in Sudan being described as one of the best in the world. Many British doctors flocked to Sudan to make a fortune and to set a path for their career back in Britain.

    The Henry's law constant for carbazole was experimentally determined between 5 and 35 degrees C using a gas-stripping technique. The following equation was obtained for dimensionless Henry's law constant (H') versus temperature (T, K): ln H' = -3982(T,K)(-1) + 1.01. Temperature-dependent octanol-air partition coefficients (KOA) and supercooled liquid vapor pressures (PL,Pa) of carbazole were also determined using the GC retention time method. The temperature dependence of KOA and PL were explained by the following: log KOA = 4076/(T,K) - 5.65, log PL(Pa) = -3948(T,K)(- 1) + 11.48. The gas and particle-phase carbazole concentrations measured previously in Chicago, IL in 1995 was used for gas/particle partitioning modeling. Octanol based absorptive partitioning model consistently underpredicted the gas/particle partition coefficients (Kp) for all sampling periods. However, overall there was a good agreement between the measured Kp and soot-based model predictions.

  4. Generation of sub-part-per-billion gaseous volatile organic compounds at ambient temperature by headspace diffusion of aqueous standards through decoupling between ideal and nonideal Henry's law behavior.

    In the analysis of volatile organic compounds in air, the preparation of their gaseous standards at low (sub-ppb) concentration levels with high reliability is quite difficult. In this study, a simple dynamic headspace-based approach was evaluated as a means of generating vapor-phase volatile organic compounds from a liquid standard in an impinger at ambient temperature (25 °C). For a given sampling time, volatile organic compound vapor formed in the headspace was swept by bypassing the sweep gas through the impinger and collected four times in quick succession in separate sorbent tubes. In each experiment, a fresh liquid sample was used for each of the four sampling times (5, 10, 20, and 30 min) at a steady flow rate of 50 mL min(-1). The air-water partitioning at the most dynamic (earliest) sweeping stage was established initially in accord with ideal Henry's law, which was then followed by considerably reduced partitioning in a steady-state equilibrium (non-ideal Henry's law). The concentrations of gaseous volatile organic compounds, collected after the steady-state equilibrium, reached fairly constant values: for instance, the mole fraction of toluene measured at a sweeping interval of 10 and 30 min averaged 1.10 and 0.99 nmol mol(-1), respectively (after the initial 10 min sampling). In the second stage of our experiment, the effect of increasing the concentrations of liquid spiking standard was also examined by collecting sweep gas samples from two consecutive 10 min runs. The volatile organic compounds, collected in the first and second 10 min sweep gas samples, exhibited ideal and nonideal Henry's law behavior, respectively. From this observation, we established numerical relationships to predict the mole fraction (or mixing ratio) of each volatile organic compound in steady-state equilibrium in relation to the concentration of standard spiked into the system. This experimental approach can thus be used to produce sub-ppb levels of gaseous volatile organic

    A study has been conducted of the future noise environment of Patric Henry Airport and its neighboring communities projected for the year 1990. An assessment was made of the impact of advanced noise reduction technologies which are currently being considered. These advanced technologies include a two-segment landing approach procedure and aircraft hardware modifications or retrofits which would add sound absorbent material in the nacelles of the engines or which would replace the present two- and three-stage fans with a single-stage fan of larger diameter. Noise Exposure Forecast (NEF) contours were computed for the baseline (nonretrofitted) aircraft for the projected traffic volume and fleet mix for the year 1990. These NEF contours are presented along with contours for a variety of retrofit options. Comparisons of the baseline with the noise reduction options are given in terms of total land area exposed to 30 and 40 NEF levels.

    Henry's Law Constants (HLC, M atm-1) were determined for the diastereomeric mixture of the nonylphenol isomer 4(3‧,5‧-dimethyl-3‧-heptyl)-phenol diastereomers (NP353(+) and NP353(-)), tertiary octylphenol (t-OP) and γ-hexachlorocyclohexane (γ-HCH) in artificial seawater over a temperature range 278-298 K using a dynamic equilibrium system. Trace organic substances present in the gas phase were trapped by tandem XAD-2 cartridges and extracted with a soxhlet extractor. The extracts were derivatived with N,O-bis(trimethylsilyl)-trifluoroacetamide (BSTFA), and then analyzed with GC-MS in the selective ion mode. At 293 K and in artificial seawater, HLC (M atm-1) were found to be equal to: NP353(+), HLC=(483±169); NP353(-), HLC=(551±193); t-OP, HLC=(400±140); γ-HCH, HLC=(876±307). The obtained data were used to derive the following Van't Hoff expressions: ln HLC (NP353(+))=8.73 (±0.95)×(1000/T) -23.61 (±3.30); ln HLC (NP353(-))=8.61 (±0.91)×(1000/T)-23.08 (±3.18); ln HLC (t-OP)=9.03 (±1.40)×(1000/T)-24.83 (±4.86); ln HLC (γ-HCH)=6.17 (±1.08)×(1000/T)-14.28 (±3.75). The derived enthalpies of solvation for NP353(+), NP353(-), t-OP and γ-HCH are -72.6±7.9, -71.6±7.6, -75.1±11.5 and -51.3±9.0 kJ mol-1, respectively. The HLC measurements of γ-HCH, which was used as reference substance, were in good agreement with literature values and its corresponding derived enthalpy of solvation agrees well to the previous values reported in the literature. A reassessment of the air/water gas exchange based on experimentally derived HLC was made for the nonylphenol (NP) in the Lower Hudson River estuary (New York/New Jersey, USA) that was previously reported by Van Ry. A net atmospheric deposition was calculated for the gas exchange of NP in the Lower Bay (Ffw=0.13), and it nearly reaches the condition of equilibrium in the Upper Bay (Ffw=0.46).

    Computers have become powerful conceptual and intellectual tools. Examples will be given showing how computer simulations clarified the nature of some important astrophysical processes: gravitational collapse to black holes or neutron stars, the synthesis of the elements, supernova explosions, and turbulent motion in stars. Originally computers were thought of as tools for solving differential equations by numerical integration, but modern use of computers more closely resembles the construction of a digital model of reality based on conservation laws. Implications of our new abilities to solve nonlinear problems, and the synergism developing between analytic and digital theory will be discussed, with historical comments.

    2015-04-01

    As Lord Kelvin observed: "If you can not measure it, you can not improve it." Measurement is the start of all scientific knowledge. Measurement sets science apart from metaphysical speculation. Measurement is not the last word in science but it is the first. In hydrology, progress in measurement methods has not been as rapid as in sister Earth sciences such as meteorology, oceanography, or geodynamics. Of the hundreds of scientific satellites, only one has hydrology as its main mission at the time of this writing (hopefully two at the time of the lecture). The closest we come to a large measurement infrastructure is an experimental watershed. Nothing wrong with an experimental watershed but it does not compare to, say, the Square Kilometer Array with its exabyte per day output. We tend to give up quickly because we will always have to work with effective parameters that can not be measured directly. We will never be able to know all stomata in a tree and how they interact with the turbulent flow through the canopy. We will never be able to know all pores in a soil and how water moves through them. But also effective parameters have to be measured, be it indirectly. No surprise then that my presentation will focus on measurements in hydrology and water management. First, the fun aspects and intellectual challenges of developing new measurement methods will be highlighted. From weighing trees to listening to rain to taking a stream's temperature, we have had many interesting experiences over the years. Second, the balance between model complexity and data availability will be discussed. Although there is a generally recognized need for parsimonious models in hydrology, formal approaches to finding the correct level of complexity are rare. Some complexity control approaches, borrowed from computer science, will be presented together with a hydrological application. As it turns out, these methods seem to predict nicely the onset of equifinality or the statistical illposedness of the inverse problem of finding effective parameters. Finally, an ambitious program will be presented that aims to shed light on Africa's climate and water resources, the TransAfrican HydroMeteorological Observatory or TAHMO. TAHMO's aim is to deploy and operate 20,000 hydroclimatological stations throughout subSaharan Africa. There are many aspects that are novel from the design of the stations, to deployment at schools, and a business model that should fund the system for decades to come. Given the global need for finding the water needed to produce our food by 2050 and the fact that Africa will have to play a major role in this effort, TAHMO addresses a scientific challenge of great societal importance.

    Aqueous solubility and vapor pressures of 1,2,3,4-dibenzanthracene and 1,2,5,6-dibenzanthracene were determined using dynamic saturation methods. For the two isomers, aqueous solubility is in the range between 10(-10) and 10(-2) in molar fraction corresponding to temperature between 298.15 and 338.15K. Vapor pressures of the pure solutes range from 10(-5) to 80 Pa. Prior to the study of the two dibenzanthracenes and in order to check the experimental procedures, solubility of fluoranthene (between 298 and 338 K) and vapor pressures of phenanthrene and fluoranthene (between 300 and 470 K) were measured. From aqueous solubility data coupled with the vapor pressures of the pure solutes, partition coefficient air-water, KAW, and Henry's constant, KH, of environmental relevance were calculated.

    Research on solar-terrestrial relationships today relies primarily on in situ space data. These data, however, cover only a short period of about 30 years. Many solar and related phenomena vary on much longer time scales. For the study of these, parameters such as sunspots, magnetic activity, auroral occurrence, or other proxy data are required. Historical records of aurora are particularly useful in this connection.

    To investigate whether single nucleotide polymorphisms (SNPs) of the Tumor Necrosis Factor Superfamily 4 (TNFSF4) gene are associated with Vogt–Koyanagi–Harada (VKH) and Behcet’s disease (BD) in a Chinese Han population. A two-stage case control study was carried out in 1331 VKH, 938 BD and 1752 healthy controls. Ten TNFSF4 SNPs, including rs1234314, rs1234315, rs2205960, rs704840, rs2795288, rs844654, rs12039904, rs10912580, rs844665, and rs844644, were genotyped using the PCR-restriction fragment length polymorphism method. Genotype and allele frequencies were analyzed between cases and healthy controls using the X2 or Fisher’s exact test and p values were corrected for multiple comparisons. We observed a significantly increased frequency of the TT genotype of rs1234315 in BD patients (Pc = 1.44 × 10−5, OR = 1.734, 95% CI = 1.398–2.151). The frequency of the TT genotype of rs12039904 was significantly higher in patients with VKH disease as compared to controls (Pc = 4.62 × 10−5, OR = 1.959, 95% CI = 1.483–2.588). Analysis of clinical manifestations in VKH disease and BD did not show an association with the TNFSF4 gene polymorphisms. The study suggests that the TNFSF4 gene may be involved in the susceptibility to VKH disease and BD in Han Chinese. PMID:27872495

  1. Water and the city (Henry Darcy Medal Lecture)

    NASA Astrophysics Data System (ADS)

    Rosso, Renzo

    2010-05-01

    Total world population is about six billion, half living in cities, one third living in slums. This figure has doubled from 1960, when urban population was less than one billion out of the total figure of 3 billion; no more than one fifth was estimated to live in slums at that time. Demography experts predict that population will be around 9 billion in 2050, two thirds (6 billion) living in urban areas, and no reasonable prediction is available for slums. History shows that water is a key factor of urbanization: springs and rivers played a fundamental role in determining where one could settle, and where we are settled now. Water availability is expected to be a major control of man's life in the next future of planet Earth. The daily municipal water withdrawal ranges from 80 to 150 liters per person in China, India and Brazil cities; can they pretend to get more than 600 liters as a US citizen currently does? The impact of natural disasters such as storms and floods is strongly linked to increasing vulnerability associated with urbanization. Are state-of-the-art mitigation policies effective in reducing this impact in both terms of human casualties and economic damage? These and similar questions are fundamental to address hydrological science and engineering hydrology in next years. This talk will approach some open problems arising from the impact of increasing urbanization on the water cycle and, mostly, the associated feedback on human life. These include the need for an insight of nonstationarity, transients and feedback control of hydrological processes; the merging of the space-time scales of hydrological processes with the spatial scales of the city, and the temporal scale of lifestyles; and the way for water scientist and engineers to be involved in the design of cities and the search for life styles coherent with a sustainable development approach.

  2. A random walk on water (Henry Darcy Medal Lecture)

    NASA Astrophysics Data System (ADS)

    Koutsoyiannis, D.

    2009-04-01

    Randomness and uncertainty had been well appreciated in hydrology and water resources engineering in their initial steps as scientific disciplines. However, this changed through the years and, following other geosciences, hydrology adopted a naïve view of randomness in natural processes. Such a view separates natural phenomena into two mutually exclusive types, random or stochastic, and deterministic. When a classification of a specific process into one of these two types fails, then a separation of the process into two different, usually additive, parts is typically devised, each of which may be further subdivided into subparts (e.g., deterministic subparts such as periodic and aperiodic or trends). This dichotomous logic is typically combined with a manichean perception, in which the deterministic part supposedly represents cause-effect relationships and thus is physics and science (the "good"), whereas randomness has little relationship with science and no relationship with understanding (the "evil"). Probability theory and statistics, which traditionally provided the tools for dealing with randomness and uncertainty, have been regarded by some as the "necessary evil" but not as an essential part of hydrology and geophysics. Some took a step further to banish them from hydrology, replacing them with deterministic sensitivity analysis and fuzzy-logic representations. Others attempted to demonstrate that irregular fluctuations observed in natural processes are au fond manifestations of underlying chaotic deterministic dynamics with low dimensionality, thus attempting to render probabilistic descriptions unnecessary. Some of the above recent developments are simply flawed because they make erroneous use of probability and statistics (which, remarkably, provide the tools for such analyses), whereas the entire underlying logic is just a false dichotomy. To see this, it suffices to recall that Pierre Simon Laplace, perhaps the most famous proponent of determinism in the history of philosophy of science (cf. Laplace's demon), is, at the same time, one of the founders of probability theory, which he regarded as "nothing but common sense reduced to calculation". This harmonizes with James Clerk Maxwell's view that "the true logic for this world is the calculus of Probabilities" and was more recently and epigrammatically formulated in the title of Edwin Thompson Jaynes's book "Probability Theory: The Logic of Science" (2003). Abandoning dichotomous logic, either on ontological or epistemic grounds, we can identify randomness or stochasticity with unpredictability. Admitting that (a) uncertainty is an intrinsic property of nature; (b) causality implies dependence of natural processes in time and thus suggests predictability; but, (c) even the tiniest uncertainty (e.g., in initial conditions) may result in unpredictability after a certain time horizon, we may shape a stochastic representation of natural processes that is consistent with Karl Popper's indeterministic world view. In this representation, probability quantifies uncertainty according to the Kolmogorov system, in which probability is a normalized measure, i.e., a function that maps sets (areas where the initial conditions or the parameter values lie) to real numbers (in the interval [0, 1]). In such a representation, predictability (suggested by deterministic laws) and unpredictability (randomness) coexist, are not separable or additive components, and it is a matter of specifying the time horizon of prediction to decide which of the two dominates. An elementary numerical example has been devised to illustrate the above ideas and demonstrate that they offer a pragmatic and useful guide for practice, rather than just pertaining to philosophical discussions. A chaotic model, with fully and a priori known deterministic dynamics and deterministic inputs (without any random agent), is assumed to represent the hydrological balance in an area partly covered by vegetation. Experimentation with this toy model demonstrates, inter alia, that: (1) for short time horizons the deterministic dynamics is able to give good predictions; but (2) these predictions become extremely inaccurate and useless for long time horizons; (3) for such horizons a naïve statistical prediction (average of past data) which fully neglects the deterministic dynamics is more skilful; and (4) if this statistical prediction, in addition to past data, is combined with the probability theory (the principle of maximum entropy, in particular), it can provide a more informative prediction. Also, the toy model shows that the trajectories of the system state (and derivative properties thereof) do not resemble a regular (e.g., periodic) deterministic process nor a purely random process, but exhibit patterns indicating anti-persistence and persistence (where the latter statistically complies with a Hurst-Kolmogorov behaviour). If the process is averaged over long time scales, the anti-persistent behaviour improves predictability, whereas the persistent behaviour substantially deteriorates it. A stochastic representation of this deterministic system, which incorporates dynamics, is not only possible, but also powerful as it provides good predictions for both short and long horizons and helps to decide on when the deterministic dynamics should be considered or neglected. Obviously, a natural system is extremely more complex than this simple toy model and hence unpredictability is naturally even more prominent in the former. In addition, in a complex natural system, we can never know the exact dynamics and we must infer it from past data, which implies additional uncertainty and an additional role of stochastics in the process of formulating the system equations and estimating the involved parameters. Data also offer the only solid grounds to test any hypothesis about the dynamics, and failure of performing such testing against evidence from data renders the hypothesised dynamics worthless. If this perception of natural phenomena is adequately plausible, then it may help in studying interesting fundamental questions regarding the current state and the trends of hydrological and water resources research and their promising future paths. For instance: (i) Will it ever be possible to achieve a fully "physically based" modelling of hydrological systems that will not depend on data or stochastic representations? (ii) To what extent can hydrological uncertainty be reduced and what are the effective means for such reduction? (iii) Are current stochastic methods in hydrology consistent with observed natural behaviours? What paths should we explore for their advancement? (iv) Can deterministic methods provide solid scientific grounds for water resources engineering and management? In particular, can there be risk-free hydraulic engineering and water management? (v) Is the current (particularly important) interface between hydrology and climate satisfactory?. In particular, should hydrology rely on climate models that are not properly validated (i.e., for periods and scales not used in calibration)? In effect, is the evolution of climate and its impacts on water resources deterministically predictable?

    By the end of his career, Sir William Broadbent (1835-1907) had become an eminent London general physician who had been appointed Physician-in-Ordinary to King Edward VII and to the Prince of Wales. Previously he had been Physician-in-Extraordinary to Queen Victoria. At earlier stages in his professional life, he had played a significant role in the development of clinical neurology in Victorian-era Britain. In 1866, he had enunciated a principle (Broadbent's hypothesis) that for the first time satisfactorily accounted for the mechanisms by which the trunk and bulbar muscles and the upper face were spared in hemiplegia. He had also carried out original investigations into the distribution of fiber tracts in the human cerebral hemispheres. At intervals over the years, he published on aspects of aphasia and developed a rather complicated though logical conceptual schema of the presumed anatomical background to the process of speech, based on clinic-pathological correlations. His role in all this neurological research and his other contributions on subjects such as neurosyphilis have largely been forgotten by subsequent generations.

    Water is the distinguishing feature of Earth. Its presence sustains life, business, energy and romance. Hydrology is the science of water. Hence, it is one of the most relevant and exciting of the planetary sciences. But, does hydrology as it is taught and practiced today achieve this potential? Is understanding and predicting the hydrological cycle really in the domain of today's hydrologists? I intend to present a personal view of some puzzles as well as fundamental issues that define hydrology as a fertile ground of scientific inquiry that emerges at the intersection of the planetary and life sciences, and of course human behavior. I plan to outline 5 main questions whose explicit or implicit pursuit characterizes the essence of the hydrological being.

    Maxillofacial reconstruction surgery largely relies on the use of microsurgical free transfer techniques. Head and neck cancer surgery and ballistic injuries may lead to significant losses of multitissular substances. Even when the free transfer is successful and the microvascular critical phase is resolved, some functions or anatomic structures may not have been properly restored or have worsened. Any plastic surgery technique may be used to improve an unfavorable functional or aesthetic result after free flap reconstruction. In most cases, performing surgical readjustments using a local flap is needed.

Ophthalmic history was significant for chronic open-angle glaucoma, for which the patient was using latanoprost once daily to both eyes. There was no preceding history of trauma or ocular surgery and the patient was emmetropic. Two weeks prior to his presentation, he reported a headache, which settled spontaneously. Slit-lamp examination demonstrated bilateral keratic precipitates, bilateral significantly shallow anterior chamber, and bilaterally normal intraocular pressures of 16 mm Hg. Fundal examination was significant for bilateral 360-degree choroidal detachments with exudative retinal detachment involving the maculae. These findings were confirmed using wide-field fundus photography, B-scan ultrasonography, and optical coherence tomography. Fundus fluorescein angiography did not reveal any evidence of retinal vasculitis. Indocyanine green chorioangiography of the posterior pole showed multiple areas of focal choroidal hypoperfusion. Extensive systemic investigation demonstrated no infectious, neoplastic, or inflammatory cause, and the patient did not complain of any systemic symptoms. Treatment with high-dose intravenous methylprednisolone was administered and this brought about complete resolution of both choroidal and retinal detachments, with partial visual recovery.

ЛПФ в верхнем и нижнем лимбе изучались на 15 здоровых добровольцах (30 глаз) без патологии переднего отрезка глаза двумя методами: ОКТ (RTVue XR Avanti) по протоколу 3D Cornea (режим En Face) и ЛСКМ (HRT3). Была оценена согласованность результатов диагностики лимбальных палисад обоими методами исследования. Результаты. Особенности структуры ЛПФ прослеживались и выявлялись по данным обоих методов исследования. У всех испытуемых 15 человек (30 глаз) по данным ЛСКМ были обнаружены ЛПФ как в верхнем, так и нижнем лимбе. В нижней гемисфере роговицы они представляли собой хорошо дифференцируемые высокорефлективные двухконтурные структуры, расположенные в виде параллельных линий или частокола на уровне базального эпителия. Структура верхнего лимба, по данным ЛСКМ, значительно варьировала: «классическая» форма палисад в виде частокола была обнаружена в 13 (43%) глазах, в остальных 17 (57%) случаях наблюдались атипичные формы. В 29 глазах метод ОКТ позволил верифицировать и детально визуализировать структуру ЛПФ. Оценка согласованности результатов диагностики ЛПФ, выполненной методами ЛСКМ и ОКТ, выявила сильную положительную связь (rS=0,99, p<0,05) в их визуализации как в верхней, так и в нижней гемисферах лимба. Заключение. Данные ОКТ позволяют детально визуализировать структуру ЛПФ и в высокой степени коррелируют с результатами ЛСКМ. Учитывая неинвазивный характер обследования, высокую информативность, наглядность, повторяемость результатов, ОКТ переднего отрезка в режиме En Face может быть рекомендована в качестве альтернативного метода диагностики ЛПФ.

  13. On Goal-Oriented, Hydrogeological Site Investigation: A Holistic Approach (Henry Darcy Medal Lecture)

    NASA Astrophysics Data System (ADS)

    Rubin, Yoram

    2016-04-01

    UQ (for Uncertainty Quantification) is a critical element of groundwater management and by extension, of hydrological site investigation. While it is clear that UQ is an important goal, there is ambiguity as to what the target of the UQ should be, and how to make UQ relevant in the context of public policy. Planning for UQ (meaning what measurements to take, where, how many, what frequency, etc.), one could consider environmental performance parameters (EPMs, such as concentrations or travel time) as the targets of site investigation. But there is a need to go beyond EPMs, and to consider the uncertainty related to impacts such as enhanced cancer-risk due to groundwater contamination or, more generally, to decisions facing regulators. In any case, UQ requires site investigation, and decision-makers, who end up paying for it, are not really interested in EPMs: they care about making operational decisions that are defensible legally and justified from the perspective of public good. The key to UQ, whether considering EPMS or operational decisions concerning the public good, is defining a suitable strategy for site investigation. There is a body of published works on relating site investigations with EPMs, but much less is known on how to support operational decisions with strategies for site characterization. In this lecture, I will address this issue and I will outline a comprehensive approach for addressing it using a statistical formalism that couples hypothesis testing with Bayesian statistics. I refer to this approach as goal-oriented site investigation. I will show how site investigation strategies, with specifics such as which measurements to take and where, could be related to goals lined with operational decisions. This includes (1) defining the relevant goals; (2) formulating hypotheses; (3) defining alternative strategies for site investigation and (4) evaluating them in terms of probabilities for making errors in accepting or rejecting the hypotheses.

  17. Genesis of the tabular-type vanadium-uranium deposits of the Henry Basin, Utah

    USGS Publications Warehouse

    Northrop, H.R.; Goldhaber, M.B.

    1990-01-01

    Tabular-type vanadium-uranium deposits occur in fluvial sandstones of the Salt Wash Member of the Morrison Formation of Late Jurassic age The mineralized intervals and the weakly mineralized lateral extensions are bounded both above and below by zones rich in dolomite cement. Carbon isotope values of dolomite cements indicate that at least two sources of carbon existed. One source appears to be the same as that which formed the bedded carbonates in the evaporites in the Tidwell Member of the Morrison Formation stratigraphically below the mineralized interval. The second carbon source is typical of terrestrially deposited carbonates generally associated with meteoric water-dominated environments. Oxygen isotope values of these dolomites show the same trend of isotopically light values above the mineralized interval and isotopically heavier values in and below that interval; they indicate that two isotopically distinct fluids were involved in the mineralizing process. Some aspects of the origin of gangue and ore phases are explainable on the basis of processes which occurred solely within the saline fluid, but key aspects of ore genesis involved the interaction of the saline and meteoric waters. It is postulated that the solution interface migrated vertically within the stratigraphic section. -from Authors

  19. Henri Tajfel's 'cognitive aspects of prejudice' and the psychology of bigotry.

    PubMed

    Billig, Michael

    2002-06-01

    This paper pays tribute to Tajfel's classic article 'Cognitive aspects of prejudice' and re-examines its central arguments. Tajfel's paper is important for outlining a social cognitive approach to the study of prejudice and also for refuting of what Tajfel called the 'blood-and-guts' approach. Taking Tajfel's proposition that social psychology is not value-free, the current paper examines the moral and political view of 'Cognitive aspects' and also the gaps in its approach to the study of prejudice. It is suggested that this cognitive approach has difficulty in accounting for extreme bigotry, at least without recourse to the motivational themes that the approach seeks to exclude. In particular, there would be limitations in applying this approach in order to understand the Holocaust. Indeed, Tajfel did not attempt to do so, for reasons that are discussed. Tajfel's Social Identity Theory (SIT) has similar limitations. The paper also examines Tajfel's use of the term 'depersonalization', which he described as a 'milder' form of dehumanization of out-groups. Later social identity theorists have tended to use 'depersonalization' differently, shifting their attention to in-groups. Their perspective moves away from understanding the topic of prejudice in the way that can be found in Tajfel's 'Cognitive aspects of prejudice'. Finally, the present paper suggests how extreme prejudice might be studied without returning to the motivational 'blood-and-guts' approach that Tajfel so cogently criticized.

  20. Geochemistry of vanadium in an epigenetic, sandstone-hosted vanadium- uranium deposit, Henry Basin, Utah

    USGS Publications Warehouse

    Wanty, R.B.; Goldhaber, M.B.; Northrop, H.R.

    1990-01-01

    The epigenetic Tony M vanadium-uranium orebody in south-central Utah is hosted in fluvial sandstones of the Morrison Formation (Upper Jurassic). Measurements of the relative amounts of V+3 and V +4 in ore minerals show that V+3 is more abundant. Thermodynamic calculations show that vanadium was more likely transported to the site of mineralization as V+4. The ore formed as V+4 was reduced by hydrogen sulfide, followed by hydrolysis and precipitation of V+3 in oxide minerals or chlorite. Uranium was transported as uranyl ion (U+6), or some complex thereof, and reduced by hydrogen sulfide, forming coffinite. Detrital organic matter in the rocks served as the carbon source for sulfate-reducing bacteria. Vanadium most likely was derived from the dissolution of iron-titanium oxides. Uranium probably was derived from the overlying Brushy Basin Member of the Morrison Formation. Previous studies have shown that the ore formed at the density-stratified interface between a basinal brine and dilute meteoric water. The mineralization processes described above occurred within the mixing zone between these two fluids. -from Authors

    Most cardiologists rarely remember that new ideas dedicated initially to completely different areas, are the technological background of most medical devices. Also, they almost ignore the bright minds beyond these ideas. The Coandă effect, vital in the color-Doppler assessment of valvular regurgitations with eccentric jets--bears the name of a Romanian inventor whose life (1886-1972) was mostly dedicated to aeronautics and who is considered the 'father' of jet engines. His fluid dynamics discovery was patented in 1934, but its importance for medical applications was recognized much later.

  2. TU-CD-BRD-02: Henry Ford Hospital System Experience, with Focus On Motivating and Reviewing

    SciTech Connect

    Miller, B.

    2015-06-15

    It has long been standard practice in radiation oncology to report internally when a patient’s treatment has not gone as planned and to report events to regulatory agencies when legally required. Most potential errors are caught early and never affect the patient. Quality assurance steps routinely prevent errors from reaching the patient, and these “near misses” are much more frequent than treatment errors. A growing number of radiation oncology facilities have implemented incident learning systems to report and analyze both errors and near misses. Using the term “incident learning” instead of “event reporting” emphasizes the need to use these experiences to change the practice and make future errors less likely and promote an educational, non-punitive environment. There are challenges in making such a system practical and effective. Speakers from institutions of different sizes and practice environments will share their experiences on how to make such a system work and what benefits their clinics have accrued. Questions that will be addressed include: How to create a system that is easy for front line staff to access How to motivate staff to report How to promote the system as positive and educational and not punitive or demeaning How to organize the team for reviewing and responding to reports How to prioritize which reports to discuss in depth How not to dismiss the rest How to identify underlying causes How to design corrective actions and implement change How to develop useful statistics and analysis tools How to coordinate a departmental system with a larger risk management system How to do this without a dedicated quality manager Some speakers’ experience is with in-house systems and some will share experience with the AAPM/ASTRO national Radiation Oncology Incident Learning System (RO-ILS). Reports intended to be of value nationally need to be comprehensible to outsiders; examples of useful reports will be shown. There will be ample time set aside for audience members to contribute to the discussion. Learning Objectives: Learn how to promote the use of an incident learning system in a clinic. Learn how to convert “event reporting” into “incident learning”. See examples of practice changes that have come out of learning systems. Learn how the RO-ILS system can be used as a primary internal learning system. Learn how to create succinct, meaningful reports useful to outside readers. Gary Ezzell chairs the AAPM committee overseeing RO-ILS and has received an honorarium from ASTRO for working on the committee reviewing RO-ILS reports. Derek Brown is a director of http://TreatSafely.org . Brett Miller has previously received travel expenses and an honorarium from Varian. Phillip Beron has nothing to report.

    A discussion is presented of the Milky Way Galaxy research trends that have recently established a far greater mass and a greater outward extent for the Galaxy than would have been considered likely only 7-8 years ago. The maximum radius of the Galaxy circa 1975 was believed to be of the order of 20 kpc. The new radius is at least three times, and possibly as much as five times, greater than the earlier value. Attention is given to such pertinent topics as the general luminosity function near the central plane of the disk, space densities at different distances from the galactic plane, the galactic corona, spiral structure studies, giant molecular clouds, and bipolar ejections.

    In order to determine the location of undeveloped water powers the United States Geological Survey has from time to time, alone and in cooperation with State organizations, made surveys and profiles of some of the rivers of the United States that are adapted to the development of power by low or medium heads of 20 to 100 feet.The surveys are made by means of plane table and stadia. Elevations are based on heights derived from primary or precise levels of the United States Geological Survey. The maps/are made in the field, and show not only the outlines of the river banks, the islands, the positions of rapids/falls, shoals, and existing dams, and the crossings of all ferries and roads, but the contours of banks to an elevation high enough to indicate the possibility of using the stream. The elevations of the various bench marks left are noted on the field sheets in their proper positions. The figures given with the gaging stations shown on the maps indicate the elevation of the zero of the gage.

    This ore deposit formed by reduction and precipitation of U and V in the presence of organic matter at the interface between a stagnant brine and overlying circulating meteoric water. Some samples of the vanadium chlorite (heated before analysis) contain = or >10% V2O5; in fresh samples most of the V is in the V3+ state. XRD data suggest that Fe and V are concentrated preferentially in the interlayer hydroxide sheets of the chlorite. A d060 value of 1.52 A indicates that the chlorite probably has a dioctahedral structure distended by the presence of octahedral Fe and V; it is a IIb polytype. The V ore zone is flanked by peripheral zones with perfectly ordered chlorite/smectite containing much less V than the pure chlorite. Chemical analysis of a sample heated to 900oC before analysis gave SiO2 44.89, Al2O3 25.14, TiO2 0.35, Fe2O3 8.29, MgO 8.47, CaO 0.84, Na2O 0.27, K2O 2.18, Li2O 0.16, UO3 0.92, V2O5 9.14, = 100.65, together with Cr 10, Mn 200, Co 150, Ni 5.8, Cu 10, Zn 140 ppm; XRD, DTG, TG and IR curves are presented. -R.A.H.

    The uptake of nitric acid by sulfuric acid solutions representative of stratospheric particulate at low temperatures was measured to determine the solubility of nitric acid in sulfuric acid solutions as a function of H2SO4 concentration and solution temperature. Solubilities are reported for sulfuric acid solutions ranging from 58 to 87 wt pct H2SO4 over a temperature range from 188 to 240 K, showing that, in general, the solubility of nitric acid increases with decreasing sulfuric acid concentration and with decreasing temperature. The measured solubilities indicate that nitric acid in the global stratosphere will be found predominantly in the gas phase.

    By the beginning of the twentieth century, most of the major discoveries concerning the nature and life cycles of parasites had been made and tropical medicine was beginning to establish itself as a discipline but parasitology still lacked any real cohesion or focus. This focus arrived in 1908 when George Nuttall founded a new journal, Parasitology, as a Supplement to the Journal of Hygiene in order to cater for increasing numbers of papers on protozoological, helminthological and entomological topics that were being submitted for publication to that journal; thus bringing these three subjects together under one heading and, in doing so, established the discipline of parasitology. The events leading up to and the subsequent development of the discipline are discussed.

    The name of Poynting is universally recognized for his development of the well-known expression for the flow of electromagnetic energy. Not so well known is Poynting's series of papers on radiation pressure, with 2011 marking the centenary of the last of his 15 publications on this topic. This paper reviews and assesses his radiation-pressure work, with a level of coverage aimed at the reader familiar with the Maxwell electromagnetic theory and interested in the current understanding of radiation pressure. We begin with brief details of Poynting's life, followed by accounts of the relevant publications by others before and during his period of activity in the field from 1903 to 1911. His contributions to the understanding of radiation-pressure effects in the solar system, and the linear and angular momenta of light are discussed, with evaluations from a modern perspective.

You have no idea how much easier it is to be sitting out there where you are than standing up here where I am” (Caira 1998). I certainly didn't imagine that Janine was delivering her advice to me and it is presumptuous to imagine my story is a template for shaping a career.

    William Dallinger illustrates a social outsider concerned with the application of science to the physical, intellectual and spiritual health of his homeland, who forced his way into the scientific life of his nation. His path was encouraged by mentors such as William McKenny who steered him into the Methodist ministry, James Drysdale who helped him get established as a scientist and John Tyndall, Thomas Huxley and Charles Darwin who encouraged his scientific efforts and smoothed his way into his nation's highest scientific circles. The shadowy figures of John Wesley and John Ray played a role in affirming the validity of his scientific interests and concerns for science education.

  16. Reactive dispersive contaminant transport in coastal aquifers: numerical simulation of a reactive Henry problem.

    The reactive mixing between seawater and terrestrial water in coastal aquifers influences the water quality of submarine groundwater discharge. While these waters come into contact at the seawater groundwater interface by density driven flow, their chemical components dilute and react through dispersion. A larger interface and wider mixing zone may provide favorable conditions for the natural attenuation of contaminant plumes. It has been claimed that the extent of this mixing is controlled by both, porous media properties and flow conditions. In this study, the interplay between dispersion and reactive processes in coastal aquifers is investigated by means of numerical experiments. Particularly, the impact of dispersion coefficients, the velocity field induced by density driven flow and chemical component reactivities on reactive transport in such aquifers is studied. To do this, a hybrid finite-element finite-volume method and a reactive simulator are coupled, and model accuracy and applicability are assessed. A simple redox reaction is considered to describe the degradation of a contaminant which requires mixing of the contaminated groundwater and the seawater containing the terminal electron acceptor. The resulting degradation is observed for different scenarios considering different magnitudes of dispersion and chemical reactivity. Three reactive transport regimes are found: reaction controlled, reaction-dispersion controlled and dispersion controlled. Computational results suggest that the chemical components' reactivity as well as dispersion coefficients play a significant role on controlling reactive mixing zones and extent of contaminant removal in coastal aquifers. Further, our results confirm that the dilution index is a better alternative to the second central spatial moment of a plume to describe the mixing of reactive solutes in coastal aquifers.

    The quality of test data is an important consideration in conducting field experiments on civil infrastructure. In addition to possible errors due to the experimental setup, the uncertainties due to incomplete knowledge of a structure's behavior and its interactions with the natural environment greatly affect the reliability of the system identification results. This paper discusses the uncertainties related to ambient vibration testing of a long-span steel arch bridge and possible ways to mitigate them. The consistency of the identified parameters is examined through statistical analyses.

    Studies related to phytoremediation by conifers are still at their beginning. Thus, we investigated the ability of a hybrid larch (Larix x eurolepis) to accumulate cadmium (Cd). One-month-old clonal plantlets grown in vitro were exposed for 1 week to a high Cd concentration (1.5 mM). No significant effect was observed on root and shoot biomass, root length, and needle number as a result of Cd treatment. Leaf photosynthetic pigment content and total soluble protein concentration in roots and shoots remained unchanged compared to control plantlets. Taken together, these results suggested that hybrid larch tolerated Cd in our conditions. The high Cd concentration in shoots (200 μg Cd gram(-1) dry weight) showed the good capacity of larch to translocate Cd and thus a potential use of this species for phytoremediation. Furthermore, under our conditions, phytochelatin biosynthesis pathway was slightly stimulated, suggesting that this pathway did not reach the threshold and/or another mechanism of Cd storage may be involved to explain larch tolerance to Cd.

    The total outflow from evaporation and ground-water flow was 5,700 acre-feet in water year 1989 and 7,710 acre-feet in water year 1990--about 19 percent evaporation and 81 percent ground-water outflow for both water years. Reservoir storage increased during both years; the change in storage was about 4,330 acre-feet in water year 1989 and about 2,890 acre-feet in water year 1990. Discrepancies between inflow, outflow, and reservoir storage reflect errors in the budget resulting from regionalization or interpretation of hydrologic data and from errors inherent in all hydrologic measurements.

    During simulation-type biodegradation tests, volatile chemicals will continuously partition between water phase and headspace. This study addressed how (1) this partitioning affects test results and (2) can be accounted for by combining equilibrium partition and dynamic biodegradation models. An aqueous mixture of 9 (semi)volatile chemicals was first generated using passive dosing and then diluted with environmental surface water producing concentrations in the ng/L to μg/L range. After incubation for 2 h to 4 weeks, automated Headspace Solid Phase Microextraction (HS-SPME) was applied directly on the test systems to measure substrate depletion by biodegradation relatively to abiotic controls. HS-SPME was also applied to determine air to water partitioning ratios. Biodegradation rate constants relating to the chemical in the water phase, kwater, were generally a factor 1 to 11 times higher than biodegradation rate constants relating to the total mass of chemical in the test system, ksystem, with one exceptional factor of 72 times for a long chain alkane. True water phase degradation rate constants were found (i) more appropriate for risk assessment than test system rate constants, (ii) to facilitate extrapolation to other air-water systems and (iii) to be better defined input parameters for aquatic exposure and fate models.

    High-density steam flash-explosion (HDSF) was first employed to extract flavonoids from pine needles. The HDSF treatment was performed at a steam pressure of 0.5-2.0 MPa for 20-120 s. Scanning electron microscopy and high-performance liquid chromatography combined with photodiode-array detection and electrospray ionization mass spectrometry (HPLC-DAD-ESI-MS) were used to characterize the morphological changes and analyze flavonoids of pine needles before and after HDSF treatment. Our results indicated that, after steam explosion at 1.5 MPa for 60 s, the flavonoids extracted reached 50.8 rutin equivalents mg/g dry weight, which was 2.54-fold as that of the untreated sample. HDSF pretreatment caused the formation of large micropores on the pine needles and production of particles, as well as the removal of wax layers. Compared to microwave-assisted, ultrasound-assisted, and solvent extraction, HDSF pretreatment took only 30 min to reach a maximum yield of 47.0 rutin equivalents mg/g flavonoids extract after pine needles were treated at 1.5 MPa for 80 s. In addition, after HDSF treatment, the aglycones were 3.17 times higher than that of untreated pine needles, while glycosides were lower by 57% (in HPLC-DAD individuals' sum) due to hydrolysis of flavonoids glycosides. It can be concluded that HDSF is a practical pretreatment for extraction of flavonoids and conversion in the healthy food and pharmaceutical industries.

    1984-10-01

    From 1970 to 1979, a group of 50 patients was treated for squamous cell carcinoma of the penis by interstitial irradiation using an afterloading technique and iridium 192 wires. The group included 9 patients with T1 tumors, 27 with T2 tumors, and 14 with T3 tumors. Forty-five patients presented with no metastatic inguinal nodes (NO), 3 patients with N1 nodes, and 2 patients had N3 nodes. After treatment, 11 patients (1 T1, 6 T2 and 4 T3) developed local recurrences. Three patients developed post-therapeutic necrosis which necessitated partial amputation in 2 cases. Eight patients developed post-therapeutic urethral stenosis, which required surgical treatment in three of the cases. Twenty-one percent of the patients died of their disease. The authors advocate interstitial irradiation using iridium 192 wires for the treatment of non-infiltrating or moderately infiltrating squamous cell carcinoma of the penis in which the largest dimension does no exceed 4 cm. When regular follow-up can be assurred, it is reasonable to forgo prophylactic treatment of the inguinal nodes in patients presenting without groin metastasis.

    The importance and reactivity consequences of the double diastereocontrol in noncovalent bifunctional organocatalysis were studied. The results suggest that the bifunctional thioureas can have synthetic limitations in multicomponent domino or autotandem catalysis. Nevertheless, we provided a means to exploit this behavior and used the configuration of the chiral catalyst as a control element in organo-sequential reactions.

  7. Map showing areas with potential for talc deposits in the Gravelly, Greenhorn, and Ruby ranges and the Henrys Lake Mountains of southwestern Montana

    1998-01-01

    For the last several years, Montana has been the leading talc producing state in the United States (U.S. Geological Survey, 1996). For example, in 1992 Montana supplied about 40 percent of the U.S. mine production of talc (Virta, 1992). All of this production has come from the large deposits of high purity talc in the southwestern part of the state. All Montana talc is currently (1997) extracted from four mines, each within the study area of this map—the open pit operations of the Treasure State, Regal, and Yellowstone mines and the underground operation of the Beaverhead mine (see map numbers 1-4 on list and map to the left). The related mineral chlorite is mined at the Antler mine, located nearby, but outside of the study area in the Highland Mountains. Montana talc has at least two market advantages: (1) some deposits are very large and near surface, allowing economic mining by open pit methods; and (2) the deposits are of high purity and lack tremolite or other amphibole mineral contaminants (such as absestos) that occur in some other talc-rich deposits. Talc from southwest Montana is used in ceramics, paint, paper, plastics, cosmetics, rubber, roofing, flooring, caulking, and agricultural applications. The talc is also used in the processes of recycling paper and plastics. Talc was first discovered in the early 1900's at the present site of the Yellowstone mine (Perry, 1948, p. 9). Modest production began in 1942 from shallow pits and adits, supplying steatite (massive, compact, high-purity) talc that was used to make ceramic insulators. The southwest Montana talc industry grew to become a significant part of the region's economy; this history is described by Perry (1948), Olson (1976), and Berg (1997). Exploration and development are likely to continue for the foreseeable future for several reasons: (1) mines are active in the area at present and an infrastructure for talc processing exists; (2) large changes in domestic and export talc markets are not expected in the next few years based on recent market trends (Virta, 1997); (3) the talc of this region is especially pure and asbestos-free; and (4) except for potential ground stabilization problems and land disturbance associated with largescale open pit mining, no significant environmental impacts are associated with talc mining

    We implemented a continuous quality improvement initiative in pursuit of a "zero-defects" performance goal in surgical pathology that required design of novel data collection tools to assess our current condition and sources of defects and waste. We defined defect as a flaw, an imperfection, or a deficiency in specimen processing requiring delaying or stopping work or returning work to the sender. These defects were noninterpretive, nondiagnostic defects critical to quality. Through a blameless work environment and contributions from all workers, we defined a baseline surgical pathology case defect rate of 27.9%, mostly arising in the laboratory (89.3%); only 8.3% were preanalytic; 2.4% resulted in amended reports. Additional focus on fidelity of patient and specimen identification allowed us to define defective identification in 1.67% of cases, with blocks and slides accounting for 78% of the defects. The misidentification defect rates per million opportunities for all sources were 4.3 to 4.8 sigma. These misidentification defects for 3 weeks required 159 hours of manual rework, or an annualized 1.3 full-time-equivalent employees. We found that through deep and honest exposure and the concerted effort of all workers, we could identify numerous sources of waste in our processes. This knowledge formed the structure for effective changes to strive toward a zero-defect performance goal.

    A 500-year-old unpreserved Mary Rose sample, historically containing an iron bolt, was analyzed using enrichment cultures and 16S sequencing. The novel community of bacteria present demonstrates a biological pathway of Fe and S oxidation and a range of acid-generating metabolisms, with implications for preservation and biogeochemical cycling.

    Kind-Harts dreame (Fig. 1) is one of the proto-novels which first appeared in the Elizabethan age of literary wonders. It recounts the dream of the hero - a tooth-drawer (Kind-Hart) - who encounters the shades of five recently deceased characters, each of whom had been a famous star of their day in the London scene. Although short, and with medicine and dentistry occupying only part of the tale, the story contains invaluable detailed information about dental care in late Tudor England as observed by a layman. It is also an amusing read.

    Accurate and timely molecular test results play an important role in patient management; consequently, there is a customer expectation of short testing turnaround times. Baseline data analysis revealed that the greatest challenge to timely result generation occurred in the preanalytic phase of specimen collection and transport. Here, we describe our efforts to improve molecular testing turnaround times by focusing primarily on redesign of preanalytic processes using the principles of LEAN production. Our goal was to complete greater than 90% of the molecular tests in less than 3 days. The project required cooperation from different laboratory disciplines as well as individuals outside of the laboratory. The redesigned processes involved defining and standardizing the protocols and approaching blood and tissue specimens as analytes for molecular testing. The LEAN process resulted in fewer steps, approaching the ideal of a one-piece flow for specimens through collection/retrieval, transport, and different aspects of the testing process. The outcome of introducing the LEAN process has been a 44% reduction in molecular test turnaround time for tissue specimens, from an average of 2.7 to 1.5 days. In addition, extending LEAN work principles to the clinician suppliers has resulted in a markedly increased number of properly collected and shipped blood specimens (from 50 to 87%). These continuous quality improvements were accomplished by empowered workers in a blame-free environment and are now being sustained with minimal management involvement.

    In marine-archaeological oak timbers of the Mary Rose large amounts of reduced sulfur compounds abound in lignin-rich parts such as the middle lamella between the cell walls, mostly as thiols and disulfides, whereas iron sulfides and elemental sulfur occur in separate particles. Synchrotron-based x-ray microspectroscopy was used to reveal this environmentally significant accumulation of organosulfur compounds in waterlogged wood. The total concentration of sulfur in reduced forms is ≈1 mass % throughout the timbers, whereas iron fluctuates up to several mass %. Conservation methods are being developed aiming to control acid-forming oxidation processes by removing the reactive iron sulfides and stabilizing the organosulfur compounds. PMID:16186503
