    The research and publications of Peter Ladefoged and his students have been a strong influence in elevating the field of phonetics to a science, and in bringing together phonetics and phonology. I will cite some examples of how Peter's work and that of his colleagues has influenced the research of many of us at MIT and around the world, where attempts to develop unifying theories often need to undergo continuous revision based on the meticulous articulatory and acoustic data that he reports in his books and other publications. These include his descriptions of the involvement of the tongue root in vowel systems, the fricatives of Mandarin Chinese, the inventory of places of articulation he catalogs in the languages of the world, and the many uses of laryngeal states in providing phonological contrasts.

    2011-05-01

    Peter Niiler, great friend, valued colleague, and AGU Fellow since 1986, will be remembered for his scientific achievements and as one of the most colorful physical oceanographers of his generation. Indeed, the Tropic Heat experiment's colors of mauve on pink, complete with Peter's matching ensemble, remain a vivid memory of that otherwise orthodox 1980s program championed by Peter to target equatorial Pacific mixing. Peter always sought understanding: to get things right for the right reason. Therefore, he held a healthy skepticism of numerical modeling and remote sensing, while utilizing both satellites and his own brand of diagnostic modeling. Peter's science motives were noble and would lead him to fight the good fight when necessary, especially when advocating his views on the Gulf Stream path, trapped inertial currents, heat and vorticity balances, and other subjects evoking his passion.

  14. Peters anomaly: review of the literature.

    PubMed

    Bhandari, Ramanath; Ferri, Sara; Whittaker, Beatrice; Liu, Margaret; Lazzaro, Douglas R

    2011-08-01

    Peters anomaly is a rare dramatic finding at birth and can be associated with other systemic malformations. We performed a literature review of multiple case reports and case series to better define the common characteristics and unusual findings associated with Peters anomaly. A representative case is discussed followed by a literature review of multiple case reports and case series. The literature search was conducted for the years 1969 to 2009. Cases and case series were included in the review of published English ophthalmic literature. Cases were excluded if no information was reported on ocular and systemic malformations or if no information was reported on surgical interventions or outcomes. In addition, if cases did not report laterality of the lesion, they were excluded from the review. Fifty-eight cases were found that fit the above criteria, and the relevant cases were reviewed to better characterize the systemic malformations, interventions, and outcomes associated with Peters anomaly reported in the literature. Fifty-eight cases of Peters anomaly were reviewed. Of those cases reporting sex, 56% were men and 44% of cases were women. In terms of laterality, 67.2% of cases were bilateral versus 32.8% of cases that were unilateral. Moreover, bilateral cases of Peters anomaly were associated with a higher rate of systemic malformations (71.8%) versus unilateral Peters anomaly (36.8%). This difference was significant (P < 0.03 by Fischer exact test). In the 15 eyes where results of penetrating keratoplasty were reported, the overall success rate was 53%. However, the success rate was significantly higher in patients with Peters anomaly type I (87.5%), as opposed to those patients with Peters anomaly type II (14.2%) (P < 0.02 by Fischer exact test). The clinical features, epidemiology, genetics, complications, and treatments of Peters anomaly are presented. Cornea specialists who care for pediatric patients should be aware of the common and uncommon

    Peters anomaly is a rare form of anterior segment ocular dysgenesis, which can also be associated with additional systemic defects. At this time, the majority of cases of Peters anomaly lack a genetic diagnosis. We performed whole exome sequencing of 27 patients with syndromic or isolated Peters anomaly to search for pathogenic mutations in currently known ocular genes. Among the eight previously recognized Peters anomaly genes, we identified a de novo missense mutation in PAX6, c.155G>A, p.(Cys52Tyr), in one patient. Analysis of 691 additional genes currently associated with a different ocular phenotype identified a heterozygous splicing mutation c.1025+2T>A in TFAP2A, a de novo heterozygous nonsense mutation c.715C>T, p.(Gln239*) in HCCS, a hemizygous mutation c.385G>A, p.(Glu129Lys) in NDP, a hemizygous mutation c.3446C>T, p.(Pro1149Leu) in FLNA, and compound heterozygous mutations c.1422T>A, p.(Tyr474*) and c.2544G>A, p.(Met848Ile) in SLC4A11; all mutations, except for the FLNA and SLC4A11 c.2544G>A alleles, are novel. This is the first study to use whole exome sequencing to discern the genetic etiology of a large cohort of patients with syndromic or isolated Peters anomaly. We report five new genes associated with this condition and suggest screening of TFAP2A and FLNA in patients with Peters anomaly and relevant syndromic features and HCCS, NDP and SLC4A11 in patients with isolated Peters anomaly.

  12. Obituary: Peter Robert Wilson, 1929-2007

    Snodgrass, Herschel B.

    2009-01-01

    It is with great sadness that I report the passing of Peter Robert Wilson, a well-known and well-loved figure in the solar physics community. Peter was on the faculty of the Department of Applied Mathematics at the University of Sydney for 39 years, and Chair of the department for 24 of these years. He was the author or co-author of more than 80 scientific research papers and a book, Solar and Stellar Activity Cycles (1994), published by Cambridge University Press. He died suddenly of a heart attack, at his home in Glebe, Australia, in the early morning of 11 November 2007. Peter was an organizer of, and participant in, many international conferences and workshops. He traveled extensively, holding visiting appointments at the University of Colorado (JILA), at Cambridge University, at the College de France (Paris), and at the California Institute of Technology [CalTech]. Most of his work was in the field of solar physics, but he also did some work on the philosophy of science and on tides. Peter came from a line of mathematicians. His father, Robert Wilson, immigrated to Australia from Glasgow in 1911, and became a mathematics teacher at Scotch College, a private school in Melbourne. There his name was changed to 'Bill' because 'Bob' was already taken." Peter's enjoyment of this story as characteristic of Australian academia (as any fan of Monty Python would understand) is indicative of his infectious sense of humor. In a similar vein, he claimed ancestry traced back to the eighteenth-century Scottish mathematician Alexander Wilson, Professor of Astronomy at the University of Glasgow. That Wilson is famous in the solar physics community for his discovery, known as the "Wilson Effect," of the photospheric depressions associated with sunspots. Peter himself could not resist writing a paper on this subject, and was delighted when the bait was taken by some less-informed colleagues who chided him for "naming an effect after himself." "Bill" Wilson married Naomi

In view of his fundamental contributions, which to a large degree have guided the progress of these disciplines over the past five decades and affected profoundly the multifaceted research published in the Journal of Quantitative Spectroscopy and Radiative Transfer (JQSRT), we felt that it would be appropriate to solicit papers for a special issue of JQSRT commemorating Peter Waterman's scientific legacy. This initiative was endorsed by the JQSRT management and has resulted in a representative collection of high-quality papers which have undergone the same peer scrutiny as any paper submitted to JQSRT.

    Peters anomaly normally presents in early childhood. Common features are central corneal opacities and dysgeneses of the anterior eye segment. Early surgery is commonly warranted to prevent deep amblyopia or because of severe glaucoma. We herein present the clinical outcomes of all patients treated in the Eye Center of the Albert Ludwigs University of Freiburg since 2005. Emphasis is placed on the Peters subtype. Data were collected retrospectively by means of chart review. Kaplan-Meier analyses were used to estimate visual prognosis, the indication for keratoplasty, and the incidence of retinal detachment. A total of 23 patients were identified. Subtype distribution was 40% type 1, 50% type 2, and 10% Peters plus syndrome. Ten patients were female (45%). Mean age at first presentation was 5 years; mean follow-up period censored in terms of eyeball preservation was 2 years (0 months-8 years). At mean follow-up, 40.5% of all patients had undergone at least one keratoplasty (up to six per eye); 43% had undergone glaucoma surgery (cylophotocoagulation, trabeculectomy, implants) at this time. Important complications were retinal detachment (31%) and phthisis bulbi (15%). After 4 years, visual acuity in the better eye was at most 0.05 in every second patient. Prognosis of visual acuity in Peters anomaly is poor. It is generally not possible to restore visual function in the long run, i. e., reading-grade visual acuity is rarely achieved. Surgical interventions are associated with a high risk of severe complications. Therefore, the young patients should be connected to institutions for visually impaired persons at an early stage.

  17. Peter Ladefoged and phonetics in the field

    NASA Astrophysics Data System (ADS)

    2005-09-01

    Among many distinctive contributions to phonetics by Peter Ladefoged is an insistence on the immense diversity of phonetic phenomena in the languages of the world, particularly at the segmental level. Because of this Peter has maintained a flexible approach to any scheme of classification or description, adapting to both new approaches and new data. Perhaps more than any other phonetician he has expected to find surprises, and has gone to far corners of the world in search of them. His ground-breaking Phonetic Study of West African Languages from 1964 laid out a template for synthesizing a large mass of data which is echoed in later works such as Preliminaries to Linguistic Phonetics and Sounds of the World's Languages. His widely used Course in Phonetics and other textbooks have shown generations of students the richness of spoken sound. But not only novel research results have marked Peter's contributions to this aspect of phonetics; equally significant are his methodological innovations in taking experimental techniques to the field. Some of the most salient steps along both these paths will be reviewed from personal and professional perspectives.

    1984-01-01

    A mineral-resource survey of the Peters Mountain Wilderness Study Area, Virginia concluded that the area contains steeply dipping and faulted clastic sedimentary rocks of Paleozoic age that have a substantiated iron resource potential and abundant rock suitable for construction materials. The area has an estimated 340 million long tons of inferred low-grade iron resources in hematitic sandstone that may average as much as 20 percent iron, or 68 million long tons of contained iron. Structural conditions favorable for hydrocarbon accumulation appear to be absent beneath the area.

    Peter Eklund grew up in Southern California and attended the University of California at Berkeley, majoring in physics. After working for one year at the Lockheed Missile and Space Company in Sunnyvale, California, he left to pursue graduate studies at Purdue University. There he carried out PhD research in strongly correlated electron and phonon systems under the supervision of J M Honig and L L van Zandt. Peter joined the group of Millie and Gene Dresselhaus at MIT in 1974 as a Postdoctoral Fellow after one year as an instructor at the University of Kentucky. At MIT, he continued work on strongly correlated systems in collaboration with Professor David Adler (who had an adjoining office), but for the most part he got excited about sp2 carbon systems and graphite intercalation compounds, a new research direction which the Dresselhaus group had started one year before Peter's arrival at MIT. Over the next 35 years Peter, Millie and Gene co-authored over 50 research articles, several review articles, and a big nine-hundred-and-fifty page book. In 1974, they saw graphite intercalation compounds as a long-neglected research direction of great promise. They studied these new materials together over the next 16 years, focusing on their optical spectroscopy. Their pioneering vibrational spectroscopy studies provided a means to characterize the fundamental properties of carbon materials. Optical spectroscopy became a centerpiece in the research portfolios of all three, both when they were together at MIT and after Peter left for the University of Kentucky in 1977 to start his independent career as an Assistant Professor of Physics. Peter became a full Professor at Kentucky in 1986. He continued to work with Millie and Gene and also acquired an ever-expanding network of students, postdocs and collaborators. As each new carbon nanostructure emerged—graphite intercalation compounds, fullerenes, carbon nanotubes, and most recently graphene—Peter was at the cutting edge

  9. Peter V. Karpovich: transforming the strength paradigm.

    PubMed

    Todd, Jan; Todd, Terry

    2003-05-01

    One of the most important figures in the public's acceptance of weight training as an acceptable activity for athletes was Russian-born physician Peter V. Karpovich of Springfield College, Springfield, MA. Karpovich, like most early 20th-century educators, opposed weight training for athletes and held a low opinion of weightlifting as an activity in general. However, he became strength science's most eminent and visible advocate after witnessing a demonstration of weightlifting organized by Bob Hoffman of the York Barbell Company in 1940. Following that demonstration, Karpovich conducted several seminal studies that examined the bedrock beliefs on which the arguments normally cited against lifting were built-that it would make a person slow and inflexible-in short, muscle-bound. His research consistently revealed that those beliefs were in error. Later, he went on to collaborate with Jim Murray on the first science-based book on the subject of strength training, Weight Training in Athletics, published in 1956.

  10. Rehabilitation: disability ethics versus Peter Singer.

    PubMed

    McPherson, Gary W; Sobsey, Dick

    2003-08-01

    This commentary discusses utilitarian bioethics currently articulated by Peter Singer, one of the most widely known bioethicists of the 21st century. His controversial concepts of personhood and replaceability have important implications for people with disabilities, caregivers, and rehabilitation in general. Singer suggests that people with severe disabilities should not be considered persons and therefore have no rights or status in ethical issues. In addition, he argues that, although some people with less severe disabilities qualify as persons, their potential quality of life is significantly compromised by disability and therefore it may be ethically desirable to eliminate them so that their resources can be used for someone with superior potential. We reject these ideas, and suggest that those involved in rehabilitation carefully consider these ideas because they imply that rehabilitation is an immoral act unless it results in full and typical function.

  11. NMR Spectroscopy: Processing Strategies (by Peter Bigler)

    Peter Bigler. VCH: New York, 1997. 249 pp. ISBN 3-527-28812-0. $99.00. This book, part of a four-volume series planned to deal with all aspects of a standard NMR experiment, is almost the exact book I have been hoping to find. My department has acquired, as have hundreds of other undergraduate institutions, high-field NMR instrumentation and the capability of doing extremely sophisticated experiments. However, the training is often a one- or two-day experience in which the material retained by the faculty trained is garbled and filled with holes, not unlike the information our students seem to retain. This text, and the accompanying exercises based on data contained on a CD-ROM, goes a long way to fill in the gaps and clarify misunderstandings about NMR processing.

    Peters Plus syndrome comprises ocular anterior segment dysgenesis (most commonly Peters anomaly), short stature, hand anomalies, distinctive facial features, and often other additional defects and is inherited in an autosomal-recessive pattern. Mutations in the β1,3-glucosyltransferase gene (B3GALTL) were recently reported in 20 out of 20 patients with Peters Plus syndrome. In our study, B3GALTL was examined in four patients with typical Peters Plus syndrome and four patients that demonstrated a phenotypic overlap with this condition. Mutations in B3GALTL were identified in all four patients with typical Peters Plus syndrome, while no mutations were found in the remaining four patients that demonstrated some but not all characteristic features of the syndrome. The previously reported common mutation, c.660+1G>A, accounted for 75% of the mutant alleles in our Peters Plus syndrome population. In addition, two new mutant alleles, c.459+1G>A and c.230insT, were identified and predicted to result in truncated protein products. These data confirm an important role for B3GALTL in causing typical Peters Plus syndrome, and suggest that this gene may not be implicated in syndromic cases that involve Peters’ anomaly but lack other classic features of this complex condition.

  14. Pilot Peter Hoag and HL-10

    NASA Technical Reports Server (NTRS)

    1969-01-01

    Air Force Major Peter Hoag stands in front of the HL-10 Lifting Body. Maj. Hoag joined the HL-10 program in 1969 and made his first glide flight on June 6, 1969. He made a total of 8 flights in the HL-10. They included the fastest lifting-body flight, which reached Mach 1.861 on Feb. 18, 1970. The HL-10 was one of five heavyweight lifting-body designs flown at NASA's Flight Research Center (FRC--later Dryden Flight Research Center), Edwards, California, from July 1966 to November 1975 to study and validate the concept of safely maneuvering and landing a low lift-over-drag vehicle designed for reentry from space. Northrop Corporation built the HL-10 and M2-F2, the first two of the fleet of 'heavy' lifting bodies flown by the NASA Flight Research Center. The contract for construction of the HL-10 and the M2-F2 was $1.8 million. 'HL' stands for horizontal landing, and '10' refers to the tenth design studied by engineers at NASA's Langley Research Center, Hampton, Va. After delivery to NASA in January 1966, the HL-10 made its first flight on Dec. 22, 1966, with research pilot Bruce Peterson in the cockpit. Although an XLR-11 rocket engine was installed in the vehicle, the first 11 drop flights from the B-52 launch aircraft were powerless glide flights to assess handling qualities, stability, and control. In the end, the HL-10 was judged to be the best handling of the three original heavy-weight lifting bodies (M2-F2/F3, HL-10, X-24A). The HL-10 was flown 37 times during the lifting body research program and logged the highest altitude and fastest speed in the Lifting Body program. On Feb. 18, 1970, Air Force test pilot Peter Hoag piloted the HL-10 to Mach 1.86 (1,228 mph). Nine days later, NASA pilot Bill Dana flew the vehicle to 90,030 feet, which became the highest altitude reached in the program. Some new and different lessons were learned through the successful flight testing of the HL-10. These lessons, when combined with information from it's sister ship, the M2

  15. Solution of Peter Winkler's Pizza Problem

    NASA Astrophysics Data System (ADS)

    Cibulka, Josef; Kynčl, Jan; Mészáros, Viola; Stolař, Rudolf; Valtr, Pavel

    Bob cuts a pizza into slices of not necessarily equal size and shares it with Alice by alternately taking turns. One slice is taken in each turn. The first turn is Alice's. She may choose any of the slices. In all other turns only those slices can be chosen that have a neighbor slice already eaten. We prove a conjecture of Peter Winkler by showing that Alice has a strategy for obtaining 4/9 of the pizza. This is best possible, that is, there is a cutting and a strategy for Bob to get 5/9 of the pizza. We also give a characterization of Alice's best possible gain depending on the number of slices. For a given cutting of the pizza, we describe a linear time algorithm that computes Alice's strategy gaining at least 4/9 of the pizza and another algorithm that computes the optimal strategy for both players in any possible position of the game in quadratic time. We distinguish two types of turns, shifts and jumps. We prove that Alice can gain 4/9, 7/16 and 1/3 of the pizza if she is allowed to make at most two jumps, at most one jump and no jump, respectively, and the three constants are the best possible.

The dynamics of their individual adjustments are examined as well as the symbiotic nature of the dyadic relationship. Other characters take their parts--Tinker Bell, Tiger Lily, and Little Lost Boys. Peter's infidelities belie a firm attachment to his Wendy/mother whilst she depends upon him for protection from forbidden impulses.

  19. Laparoscopic cholecystectomy and the Peter Pan syndrome.

    PubMed

    Orlando, G; Bellini, P; Borioni, R; Pace, A

    2000-08-01

    We report the case of a patient who experienced hemobilia a few weeks after undergoing laparoscopic cholecystectomy (LC). This condition was due to the rupture of a pseudo-aneurysm of the right hepatic artery in the common bile duct, probably caused by a clip erroneously fired during LC on the lateral right wall of the vessel. It also caused the formation of multiple liver abscesses and the onset of sepsis. This life-threatening complication led to melena, fever, epigastric pain, pancreatitis, liver dysfunction, and severe anemia, requiring urgent hospitalization and operation. In the operating theater, the fistula was closed, the liver abscesses drained, and a Kehr tube inserted. Thereafter, the patient's general condition improved, and she is now well. LC is often considered to be the gold standard for the management of symptomatic cholelithiasis. However, recent data have undermined that opinion. The apparent advantages offered by LC in the short term (less pain, speedier recovery, shorter hospital stay, and lower costs) have been overwhelmed by the complications that occur during long-term follow-up. When the late downward trend in the bile duct and the vascular injury rate are taken into consideration, the learning curve is prolonged. Therefore, LC should be regarded as the surgical equivalent of a modern Peter Pan-i.e., it is like a young adult who should make definitive steps toward becoming an adult but does not succeed in doing so. We report the case of a patient who experienced hemobilia a few weeks after undergoing laparoscopic cholecystectomy. Based on the facts in this case, we argue that the endoscopic procedure still needs to be perfected and cannot yet be considered the gold standard for selected cases of gallstone disease.

  20. Peter Holland: a pioneer of occupational medicine.

    PubMed Central

    Murray, R

    1992-01-01

    The earliest recorded occupational health service in this country was that established in a cotton spinning factory at Quarry Bank Mill in Cheshire. The mill was built in 1784 by Samuel Greg and his partners. They employed local labour and also some parish apprentices. Happily, Samuel Greg was a good christian and, having created a modern factory and a model village with a church and a school, he was equally concerned for the physical welfare of his employees. Accordingly, he appointed a doctor to make pre-employment examinations of the apprentices and to visit regularly to deal with the health problems of a community of some 400 people. The man he chose was Peter Holland of Sandlebridge, who had served his medical apprenticeship under Dr Charles White of Manchester. The first record of the employment of a doctor was in 1796, but from 1804 to 1845 (doubtless in response to the early factory legislation) each visit of the doctor was entered in a day book with either an indication of fitness to work or details of the treatment required. The complete record consists of two hardback foolscap notebooks that provide a fascinating insight into the medical practice of the times when the industrial revolution was just getting under way. One of the more interesting features is the preservation of medical secrecy. Dr Holland made his comments on the case in shorthand and his instructions in longhand. By a fortunate coincidence the key to the shorthand was discovered and this has now been largely transcribed. Although much of the content of the diaries is the day by day practice of medicine at the time, there are many illuminating glimpses of the early practice of occupational medicine.

    PubMed

    Durà-Vilà, G; Bentley, D

    2009-12-01

    In this paper, Britten's opera Peter Grimes (1945) is used as an illustrative case study through which to examine the depiction of psychiatric disorders in opera. It is argued that Peter Grimes is a powerful example of how opera, in the hands of a great composer, can become an invaluable tool for examining subjective human experience. After a brief discussion of opera as a vehicle to express emotions, various operas are drawn upon to provide a historical perspective and to demonstrate the long interconnection existing between opera and madness. An in-depth analysis of Peter Grimes, its background and central character, is then provided, in order to demonstrate how opera can elicit empathy for individuals affected by mental health problems.

Ever since, his so-called "transcendental argument" has been under attack and most critics conclude that it does not work. They have, however, thrown the baby away with the bathwater, when they furthermore concluded that…

    2008-01-01

    The middle of the 20th century hailed the realization that patients with Hodgkin disease could be cured. Through the groundbreaking work of Vera Peters, patients with a localized form of the disorder, previously thought to be incurable, were shown to be cured by extended-field radiotherapy. This important observation, although not immediately accepted, opened the minds of physicians to take more positive investigative and therapeutic approaches. Peters also introduced and championed the concept of tumour staging in Hodgkin disease and the use of prognostic factors in clinical decision-making. This novel approach led to high cure rates with radiotherapy in localized disease and provided a scientific basis for the subsequent use of chemotherapy in disseminated disease, resulting in a very high cure rate in patients with all stages of Hodgkin disease.

    Peter Satir has devoted his research career to elucidating the structural basis for ciliary motility. His ingenious use of structural analysis, combined with identification of powerful model systems, provided a model for the sliding microtubule hypothesis of ciliary bending and led to the discovery that dynein is a 'minus-end'-directed motor whose regulated activity underpins the bending motion of cilia. Here, we focus on ciliary motility to illustrate Satir's pioneering contributions to cell biology.

    Abnormal centromere-chromatid apposition (ACCA) was noted in a patient with Peters' anomaly. Previous reports of ACCA emphasized its association with tetraphocomelia and other congenital malformations (Roberts, SC Phocomelia, Pseudothalidomide Syndromes). This report expands the array of congenital malformations associated with ACCA and emphasizes the diagnostic importance of ocular defects for the ascertainment of additional cases of ACCA and its possible relationship with abnormal cell division.

    PubMed

    Adams, Matthew S

    2016-01-01

    The work of Herbert Spencer was a crucial influence on the development of Peter Kropotkin's historical sociology. However, scholars have underestimated this relationship; either overlooking it entirely, or minimizing Kropotkin's attachment to Spencer with the aim of maintaining the utility of his political thought in the present. This article contests these interpretations by analyzing Kropotkin's reading of Spencer's epistemological, biological, and political ideas. It argues that Kropotkin was engaged in a critical dialogue with Spencer, incorporating many Spencerian principles in his own system, but also using this reading to articulate a distinctive anarchist politics.

  11. A tribute to Peter A. Rona: A Russian Perspective

    In July 1985 Peter Rona led a cruise of the National Oceanic and Atmospheric Administration (NOAA) ship Researcher as part of the NOAA Vents Program and discovered, for the first time, black smokers, massive sulfide deposits and vent biota in the Atlantic Ocean. The site of the venting phenomena was the Trans-Atlantic Geotraverse (TAG) Hydrothermal Field on the east wall of the rift valley of the Mid-Atlantic Ridge at 26°08‧N; 44°50‧W (Rona, 1985; Rona et al., 1986). In 1986, Peter and an international research team carried out multidisciplnary investigations of both active and inactive hydrothermal zones of the TAG field using the R/V Atlantis and DSV Alvin, discovering two new species of shrimp (Rimicaris exoculata and Chorocaris chacei) (Williams and Rona, 1986) and a hexagonal-shaped form (Paleodictyon nodosum) thought to be extinct (Rona et al., 2009). In 1991 a Russian crew aboard the R/V Akademik Mstislav Keldysh, with two deep-diving, human-occupied submersibles (Mir-1 and Mir-2) (Fig. 1), had the honor of having Peter Rona and a Canadian IMAX film crew from the Stephen Low Company on board to visit the TAG hydrothermal vent field. This was the first of many deep-sea interactions between Russian deep-sea scientists and their colleagues from both the U.S. and Canada. This expedition to the TAG site was part of a major Russian undersea program aimed at exploring extreme deep-sea environments; between 1988 and 2005, the Mir submersibles visited hydrothermal vents and cold seep areas in 20 deep-sea regions throughout the world's oceans (Sagalevich, 2002). Images of several of these areas (the TAG, Snake Pit, Lost City and 9°50‧N vent fields) were obtained using an IMAX camera system emplaced for the first time within the spheres of the Mir submersibles and DSV Alvin in conjunction with the filming of science documentaries (e.g., ;Volcanoes of the Deep Sea;) produced by the Stephen Low Company in conjunction with Emory Kristof of National Geographic and

    John Peters and his committee had a few basic goals. One was that local, state, and federal governments needed to provide money to construct facilities, support medical research and education, and care for the poor. And they wanted experts to call the shots. Over time, Peters and the committee got what they wanted for the most part: Hill-Burton money for building the hospitals, the rise of the National Institutes of Health, Medicare, Medicaid, a Veterans Administration system, and new and expanded medical schools. The experts calling the shots included David Kessler at the Food and Drug Administration and Surgeon General C. Everett Koop. In the halcyon days of American health system reform, back in 1993, Yale's Paul Beeson wrote about the Committee of 430 Physicians and its goals in the Pharos of Alpha Omega Alpha.

    To report an unusual case of bilateral Peters anomaly in Peters Plus syndrome. Systematic analysis and description of relevant clinical features, histopathological, and genetic findings. A premature neonate, born after 34 weeks of gestation, presented with typical features of Peters Plus syndrome and bilateral corneal opacification with central clearing. Peters Plus syndrome was confirmed by the identification of a homozygous mutation in the B3GALTL gene. When a flat anterior chamber was observed and perforation was suspected both corneas necessitated corneal transplantation (left cornea transplanted at 4 weeks of age, right cornea at the age of 9 weeks). Histopathological analysis of the left cornea revealed a central defect with absence of all corneal layers except for the corneal epithelium. The right cornea revealed central absence of the corneal endothelium and Descemet membrane as well, but the central stroma consisted of a cellular meshwork rich in fibroblasts. There were no signs of iridocorneal or keratolenticular adhesions. We report the histopathology of serially obtained left and right cornea of a premature neonate with Peters Plus syndrome. As demonstrated in the left cornea, the child had a central defect of all corneal layers except for the corneal epithelium. Histopathological analysis of the right cornea obtained 5 weeks later revealed that the defect had induced fibrovascular tissue repair. The sequence of events we report in the corneas of our patient may help to better understand the pathogenesis of corneal (and anterior chamber) abnormalities in Peters Plus syndrome.

In this analysis his historical physiognomy of scientist and physician is reconstructed on the basis of a better knowledge of his works in medicine and astronomy (now edited), a discipline, the latest one, in which he excelled in Medieval scientific context (The Lucidator dubitabilium astronomiae (astrologiae) can be read in the critical edition by G. Federici Vescovini, Padova, Esedra, 1992). He opposed extreme position in all fields, by styling himself 'Conciliator' of opposed tendencies. He often reconfirmed a rational concept of medicine and astronomy, which dispelled any demoniac and magic features, against the fanciful legend elaborated during the following centuries.

    Groups of St Peter's fish Sarotherodon galilaeus were trained during 28 days of classical conditioning to respond to an acoustic signal by approaching a feeder. Their ability to retain the acoustically conditioned behaviour was tested after eight different intervals ranging from 12 to 188 days from termination of training. Retention tests comprised 7 consecutive days of retraining and the fish response was compared with that of naive fish. Fish response drastically diminished with time. After 55 days, there was no apparent expression of memory on the first test day but fish response was restored on subsequent retraining days, indicating the existence of latent memory. Six months from the end of training, there was no indication of behavioural retention and the response completely vanished. The study was conducted in the context of sea ranching, with classical conditioning used to gain control over fish location. In light of the present results, it is suggested that periodic reinforcement of the acoustically conditioned behaviour should be used.

    The publications by Peter B.

The series of articles were rigorous in their approach, dramatic in terms of the results, and provocative in their implications. Published at the near half-century mark of the founding of the American Society for Pharmacological and Experimental Therapeutics, it is appropriate to now provide a Centennial Perspective on the impact of these studies over 50 years following their publication and to comment on the way in which they helped to influence the directions in which this discipline has evolved.

    2014-09-01

    A 10-mo-old female red kangaroo (Macropus rufus) presented with a unilateral congenital corneal opacity OD. Complete ophthalmic examination revealed a shallow anterior chamber and a focal area of corneal edema with multiple persistent pupillary membranes extending from the iris colarette to the corneal endothelium adjacent to the edematous area of cornea. High-resolution B-scan ultrasound of the anterior segment showed an area consistent with thinning of Descemet's membrane in the area of corneal edema. Ophthalmic examination and ultrasound findings are consistent with a diagnosis of Peters anomaly, a form of anterior segment dysgenesis. An electroretinogram performed on the affected animal did not reveal any specific abnormalities. Karyotype analyses revealed a normal diploid number (2n = 20, -XX), with an abnormal pericentric inversion in the second largest chromosomal pair. The kangaroo exhibits mild compensated vision deficits in the affected eye. The maternal and paternal adult pairing has been discontinued in an effort to prevent future offspring anomalies.

  10. 1988 Horton Medal presented to Peter S. Eagleson

    NASA Astrophysics Data System (ADS)

    Rodriguez-Iturbe, Ignacio; Eagleson, Peter S.

    It is indeed a great honor for me, and also a great pleasure, to present to you the 1988 recipient of the Robert E. Horton Medal, Peter S. Eagleson. Shortly after it became public that Pete was the winner of this year's medal, I commented to my wife that, although I had never given a citation for an AGU medalist, this was one I would really love to give. The reason is simple: there is no one in the world who better represents the standards of excellence that a hydrologist hopes to achieve and that hydrologists hope our discipline will attain than Peter Eagleson.Pete did not start his research career in hydrology. In fact, his Ph.D. thesis in 1956 and his research up to 1965 were mainly in the field of sediment sorting and transport by waves on beaches. During this period he also investigated problems related to flow-induced vibrations of plates. His research in these areas was extremely successful, producing three chapters in books and about 20 journal papers in addition to many technical reports and journal discussions. Indeed, Pete had made his mark in wave theory and sediment transport, but it was good fortune for our field that starting about 1964 his interest in hydrology overcame all his past experience and assured a reputation in the waves and sediment field, and thus he embarked on a new adventure—bringing into hydrology the scientific rigor that existed in more academically established disciplines. With his strong fluid mechanics background—he still teaches that subject to undergraduates at MIT—Pete was ideally suited to lead the field toward new problems and also toward new approaches to old problems . . . and this he did indeed! Just in 1967 he and his students published six papers, most of them in Water Resources Research, which had a strong, an almost immediate impact on the field of hydrology. Here was somebody who was tackling the modeling of overland flow with the scientific standards of fluid mechanics. At the same time, finally somebody had

    The expansion of a square integrable function on SL(2, C) into the sum of the principal series matrix coefficients with the specially selected representation parameters was recently used in the Loop Quantum Gravity [C. Rovelli and F. Vidotto, Covariant Loop Quantum Gravity: An Elementary Introduction to Quantum Gravity and Spinfoam Theory (Cambridge University Press, Cambridge, 2014) and C. Rovelli, Classical Quantum Gravity 28(11), 114005 (2011)]. In this paper, we prove that the sum used originally in the Loop Quantum Gravity: ∑ j = 0 ∞ ∑ |m| ≤ j ∑ |n| ≤ j Dj m , j n ( j , τ j ) ( g ) , where j, m, n ∈ Z, τ ∈ C is convergent to a function on SL(2, C); however, the limit is not a square integrable function; therefore, such sums cannot be used for the Peter-Weyl like expansion. We propose the alternative expansion and prove that for each fixed m: ∑ j = m ∞ D j m , j m ( j , τ j ) ( g ) is convergent and that the limit is a square integrable function on SL(2, C). We then prove the analog of the Peter-Weyl expansion: any ψ(g) ∈ L2(SL(2, C)) can be decomposed into the sum: ψ ( g ) = ∑ j = m ∞ j 2 ( 1 + τ 2 ) c j m m D j m , j m ( j , τ j ) ( g ) , with the Fourier coefficients c j m m = ∫ S L ( 2 , C ) ψ ( g ) Dj m , j m j , τ j ( g ) ¯ d g , g ∈ SL(2, C), τ ∈ C, τ ≠ i, - i, j, m ∈ Z, m is fixed. We also prove convergence of the sums ∑ j = |p| ∞ ∑ |m| ≤ j ∑ |n| ≤ j dp m /j 2 Dj m , j n ( j , τ j ) ( g ) , where d|p| m /j 2 = ( j + 1 ) /1 2 ∫ S U ( 2 ) ϕ ( u ) D|p| m /j 2 ( u ) ¯ d u is ϕ(u)'s Fourier transform and p, j, m, n ∈ Z, τ ∈ C, u ∈ SU(2), g ∈ SL(2, C), thus establishing the map between the square integrable functions on SU(2) and the space of the functions on SL(2, C). Such maps were first used in Rovelli [Class. Quant. Grav. 28, 11 (2011)].

    Suchting, W. A.

    The paper examines central parts of the first of two papers in this journal by Peter Slezak criticising sociology of scientific knowledge and also considers, independently, some of the main philosophical issues raised by the sociologists of science, in particular David Bloor. The general conclusion is that each account alludes to different and crucial aspects of the nature of knowledge without, severally or jointly, being able to theorise them adequately. The appendix contains epistemological theses central to a more adequate theory of scientific knowledge.... our Histories of six Thousand Moons make no Mention of any other, than the two great Empires of Lilliput and Blefuscu. Which mighty Powers have ... been engaged in a most obstinate War for six and thirty Moons past. It began upon the following Occasion. It is allowed on all Hands, that the primitive Way of breaking Eggs before we eat them, was upon the larger End: But ... the Emperor [of Lilliput] ... published an Edict, commanding all his Subjects, upon great Penalties, to break the smaller End of their Eggs. The People so resented this Law, that ... there have been six Rebellions raised on that Account ... These civil Commotions were constantly fomented by the Monarchs of Blefuscu ... It is computed, that eleven Thousand have, at several Times, suffered Death, rather than break Eggs at the smaller End. Many hundred large Volumes have published upon this Controversy ...

    The aim of this paper is to provide a short history of the changes in Ferenczi's concept of early childhood, during the two decade period, 1913-1932. Initially, Ferenczi mainly emphasized children's feelings of omnipotence, which enable them to perceive themselves as strong, independent and capable human beings. By the mid-1920s, however, he felt that his earlier work did not give a good account of what comes after the stage of omnipotence, and that it did not adequately describe the difficulties in the transition from pleasure to reality principles. However, in his Clinical Diary, Ferenczi became fully aware of how fragile and insecure children are, and therefore how dangerous-yet necessary-it is for them to abandon the "stage of omnipotence" and to gain a "sense of reality". For Ferenczi, traumatized children are children who had not been loved in their early childhood, and therefore could not develop the capacity to make the journey from pleasure principle to that of reality. It will be suggested that a paradigmatic example for this kind of child is Peter Pan.

    Peter C. Agre, an American Society of Nephrology member, is the recipient of the 2003 Nobel Prize in Chemistry for his discovery of the aquaporin water channels. The function of many cells requires that water move rapidly into and out of them. There was only indirect evidence that proteinaceous channels provide this vital activity until Agre and colleagues purified aquaporin-1 from human erythrocytes and reported its cDNA sequence. They proved that aquaporin-1 is a specific water channel by cRNA expression studies in Xenopus oocytes and by functional reconstitution of transport activity in liposomes after the incorporation of the purified protein. These findings sparked a veritable explosion of work that affects several long-standing areas of investigation such as the biophysics of water permeation across cell membranes, the structural biology of integral membrane proteins, the physiology of fluid transport in the kidney and other organs, and the pathophysiological basis of inherited and acquired disorders of water balance. Agre's discovery of the first water channel has spurred a revolution in animal and plant physiology and in medicine.

  19. Sophus Peter Tromholt: an outstanding pioneer in auroral research

    Moss, K.; Stauning, P.

    2012-03-01

    The Danish school teacher Sophus Peter Tromholt (1851-1896) was self-taught in physics, astronomy, and auroral sciences. Still, he was one of the brightest auroral researchers of the 19th century. He was the first scientist ever to organize and analyse correlated auroral observations over a wide area (entire Scandinavia) moving away from incomplete localized observations. Tromholt documented the relation between auroras and sunspots and demonstrated the daily, seasonal and solar cycle-related variations in high-latitude auroral occurrence frequencies. Thus, Tromholt was the first ever to deduce from auroral observations the variations associated with what is now known as the auroral oval termed so by Khorosheva (1962) and Feldstein (1963) more than 80 yr later. He made reliable and accurate estimates of the heights of auroras several decades before this important issue was finally settled through Størmer's brilliant photographic technique. In addition to his three major scientific works (Tromholt, 1880a, 1882a, and 1885a), he wrote numerous short science notes and made huge efforts to collect historical auroral observations (Tromholt, 1898). Furthermore, Tromholt wrote a large number of popular science articles in newspapers and journals and made lecture tours all over Scandinavia and Germany, contributing to enhance the public educational level and awareness. He devoted most of his life to auroral research but as a self-taught scientist, he received little acclaim within the contemporary academic scientific society. With his non-academic background, trained at a college of education - not a university - he was never offered a position at a university or a research institution. However, Sophus Tromholt was an outstanding pioneer in auroral research.

  20. Ordovician conodonts and stratigraphy of the ST. Peter sandstone and glen wood shale, central United States

    Witzke, B.J.; Metzger, R.A.

    2005-01-01

    The age of the St. Peter Sandstone in the central and northern Midcontinent has long been considered equivocal because of the general absence of biostratigraphically useful fossils. Conodonts recovered from the St. Peter Sandstone in Iowa, Minnesota, Nebraska, and Kansas for this study help place some age constraints on this renowned formation in its northern and western extent. Faunas from the lower St. Peter include Phragmodus flexuosus, Cahabagnathus sp., and Leptochirognathus sp., and a late Whiterockian (Chazyan) correlation is indicated. Juvenile or immature elements of P. flexuosus from these collections show morphologies trending toward P. cognitus and P. inflexus, and paedomorphic derivation of these latter species is proposed. Diverse assemblages of hyaline forms also occur in the St. Peter strata (Erismodus spp., Erraticodon sp., Curtognathus sp., Coleodus sp., Archeognathus sp., Stereoconus sp., others) along with various albid elements (Plectodina sp., Eoplacognathus sp., others). The overlying Glenwood Shale contains abundant conodonts dominated by Phragmodus cognitus, Erismodus sp., and Chirognathus duodactylus, and the fauna is interpreted as an early Mohawkian (Blackriveran) association. Certain thin shale units in the St. Peter-Glenwood succession represent condensed intervals, in part reflected by their exceptionally high conodont abundances. Some organic-rich phosphatic shale units in the lower St. Peter of western Iowa have produced equivalent yields of tens of thousands of conodonts per kilogram, and many Glenwood Shale samples yield thousands of conodonts per kilogram. Previous depositional models have proposed that the St. Peter is primarily a succession of littoral and nearshore facies forming a broadly diachronous transgressive sheet sand. However, broad-scale diachroneity cannot be demonstrated with available biostratigraphic control.

    The manuscript entitled "My pharmacopoeia Peter Bodmer in Därligen--1836" [Arzeneybuch mein Peter Bodmer in Därligen pro. 1836] contains a collection of a total of 227 remedies for the treatment of cattle, horses, pigs and human beings. The author Peter Bodmer was born on 15 November 1811 in Därligen on the shores of Lake Thun and worked as a smith and a cattle doctor. The manuscript cannot offer a full overview of the therapeutic possibilities in veterinary medicine at that time. The remedies mainly describe the peroral dispensing of herbal preparations. The use of medicinal plants, however, would only partially measure up to modern phytotherapy. Bodmer's manuscript provides a certain insight into the traditional herbal folk remedies used on animals and humans in the rural Bernese Oberland at that time.

    Two sibling snow leopards, a male and a female, with bilateral anterior segment dysgenesis (ASD), are reported. Both snow leopards also had colobomas of both upper eyelids. All eyes exhibited a central corneal opacity associated with a defect in posterior corneal stroma, endothelium and Descemet's membrane. Iris strands were present attached to the termination of Descemet's membrane and to the periphery of the posterior corneal defect. The iris was hypoplastic, and cataract was present in all four eyes. The left eye of the female was microphthalmic, with no trabecular meshwork and with persistent remnant of the hyaloid artery. The male had hydrocephalus and thus some of the features of Peters' plus syndrome (Peters' anomaly in addition to systemic malformations). The histological findings in the eyes of these snow leopard siblings are identical with those described in humans with Peters' anomaly.

    Peter Agre, born in 1949 in Northfield Minnesota, shared the 2003 Nobel Prize in Chemistry with Roderick MacKinnon for his discovery of aquaporins, the channel proteins that allow water to cross the cell membrane. Agre's interest medicine was inspired by the humanitarian efforts of the Medical Missionary program run by the Norwegians of his home community in Minnesota. Hoping to provide new treatments for diseases affecting the poor, he joined a cholera laboratory during medical school at Johns Hopkins. He found that he enjoyed biomedical research, and continued his laboratory studies for an additional year after medical school. Agre completed his clinical training at Case Western Hospitals of Cleveland and the University of North Carolina, and returned to Johns Hopkins in 1981. There, his serendipitous discovery of aquaporins was made while pursuing the identity of the Rhesus (Rh) antigen. For a century, physiologists and biophysicists had been trying to understand the mechanism by which fluid passed across the cell's plasma membrane. Biophysical evidence indicated a limit to passive diffusion of water, suggesting the existence of another mechanism for water transport across the membrane. The putative "water channel," however, could not be identified. In 1988, while attempting to purify the 30kDa Rh protein, Agre and colleagues began investigating a 28 kDa contaminant that they believed to be a proteolytic fragment of the Rh protein. Subsequent studies over the next 3-4 years revealed that the contaminant was a membrane-spanning oligomeric protein, unrelated to the Rh antigen, and that it was highly abundant in renal tubules and red blood cells. Still, they could not assign a function to it. The breakthrough came following a visit with his friend and former mentor John Parker. After Agre described the properties of the mysterious 28 kDa protein, Parker suggested that it might be the long-sought-after water channel. Agre and colleagues tested this idea by

    Peters anomaly is a form of anterior segment dysgenesis characterized by central ocular opacity and corneo-lenticular adhesions. Isolated and syndromic Peters anomaly can be observed and demonstrate significant genetic heterogeneity. We report the identification of overlapping 8q21.11 deletions in two patients with syndromic Peters anomaly via whole exome sequencing and chromosomal microarray analyses. Microdeletions of 8q21.11 were recently reported in 10 patients with highly variable phenotypes involving craniofacial features, ptosis, intellectual disability, abnormalities of the hands/feet and other defects; sclerocornea and/or microphthalmia were reported in three cases. The two additional cases presented in this report expand the phenotypic spectrum of 8q21.11 microdeletions to include Peters anomaly (seen in both patients) and persistent primary dentition (seen in one patient with a larger deletion). The two novel deletions include the ZFHX4 and PEX2 genes, which were also affected in all three previous cases involving ocular anomalies. Screening of the remaining alleles of ZFHX4 and PEX2 did not identify any additional likely pathogenic variants in either patient, suggesting a dominant mechanism (haploinsufficiency) for the identified deletion. This report provides further insight into the phenotypes associated with 8q21.11 deletions and, for the first time, reports Peters anomaly as an additional ocular feature; screening for copy number variations of the 8q21.11 region should be considered in patients with Peters anomaly and related syndromic features. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

    To present in vivo anterior segment optical coherence tomography (OCT) features of infants with Peters' anomaly obtained during presurgical examination under general anaesthesia, and to evaluate the impact of OCT features on surgical decision making. This is a single-centre, consecutive, observational case series including 44 eyes of 27 infants with Peters' anomaly (5-18 months) undergoing keratoplasty. Medical records of patients were reviewed retrospectively. Clinical features and OCT findings, along with their impact on surgical decision-making were analysed. Of 27 patients, 10 had unilateral and 17 had bilateral disease. Two patients with mild disease (three eyes) had a posterior corneal defect with leukoma (2/27, 7.4%). Twenty patients (32 eyes) with iridocorneal adhesions were classified as having moderate Peters' anomaly (20/27, 74.1%) and five patients (nine eyes) with lenticulocorneal adhesions were classified as having severe Peters' anomaly (5/27, 18.5%). The range of angle closure, anterior chamber depth and maximum iridocorneal adhesion length (all p<0.001) were significantly different among groups, indicating that they might serve as novel OCT parameters for assessing the severity of Peters' anomaly. The surgical approach in seven patients (21.2%) was altered in response to intraoperative OCT findings, which provided information regarding the anatomical structure of the anterior chamber not provided by the surgical microscope. The use of OCT prevented unnecessary cataract surgeries in five patients. Our study showed that information gained from OCT under anaesthesia allows surgeons to classify type and severity of Peters' anomaly and supports surgical decision making.

    Despite steadfast denials by Ernest Jones, Peter Gay and Paul Roazen (among others), a recent discovery by Franz Maciejewski renders it reasonably certain that Freud had an affair with his sister-in-law, Minna Bernays. While this discovery vindicates certain claims made by the controversial Freud scholar, Peter Swales, other claims of his vis-a-vis Freud's personality and ideas are open to doubt. Meanwhile, the reception of Swales's ideas, and indeed the whole controversy about Freud's love life, provide ample confirmation of many of Erich Fromm's prescient theses about Freud's personality and the politics and historiography of psychoanalysis.

  9. [Questions on the first operation with ethyl ether as anaesthetic by Dr. Peter Parker].

    PubMed

    Chen, Q

    2017-01-28

    Ethyl ether was the first accepted effective general anaesthetic. It was introduced into China by an America missionary, Dr. Peter Parker. This was one of the historical events of medical communication between China and the West. In the records of the first operation with ether, however, Dr. Parker unusually omitted the patient's medical record number and the date of the operation, while those of other operations with ether anesthetics were all available. This was very unusual for a doctor like Peter Parker who always recorded every important case in detail in the hospital reports. It seems that he deliberately rather than carelessly omitted the information for some reasons. Based on the analysis of Parker's reports, a conclusion is made that the anesthetic effect of the case was actually ineffective. Furthermore, possible answers to this are outlined and question by discussion based on the situation that Parker faced in the late Qing era.

  10. Peter of Spain's handling of authorities in his commentary on the Isagoge of Johannitius.

    PubMed

    De Asua, M

    2000-01-01

    The dicta from medical and philosophical authorities appearing in commentaries on the Isagoge of Johannitius may be classified according to the different roles they play in the exposition of the text. This paper establishes that the opinions of the philosophical and medico-philosophical authorities were used more frequently as the consituent elements of inferences, whereas the dicta of purely medical authorities were quoted straightforwardly as sententiae. An exception to this is Peter of Spain who does not follow any hierarchical organization of authorities; instead, he freely quotes Aristotle in opposition to the physicians as well as in support of them. These observations are explained with specific reference to Peter's ideas on the relationsip between medicine and philosophy.

  15. Peters Anomaly in Twins: A Case Report of a Rare Incident with Novel Comorbidities.

    Peters anomaly is a rare developmental malformation involving the anterior segment of the eye, which culminates in amblyopia or congenital blindness. Multiple ocular and/or systemic malformations have been observed with this anomaly, and novel comorbidities continue to be reported. The probands were monozygotic twin boys (twin I and twin II) born to consanguineous parents at 36 weeks of gestation. Coarse facial features and deep-seated eyes were noted at birth. At 6 months, ophthalmic examination revealed that both twins were unable to blink in response to light, or to fixate and follow a moving object. Both twins had prominent horizontal nystagmus. Slit-lamp examination demonstrated varying degrees of central leukoma (corneal opacity) associated with iridocorneal adhesion, which is characteristic of type I Peters anomaly. No cataractous changes were observed. Normal intraocular pressure and disorganized retina were observed. Pupillary abnormalities included bilaterally underdeveloped pupils and bilateral absence of pupils was noted. Ocular MRI showed bilateral microphthalmia and optic nerve hypoplasia, with a small optic chiasm in both twins. At this age, the diagnosis of Peters anomaly was made. At 16 months of age, both twins developed deep venous thrombosis and purpuric skin lesions. Investigations revealed a hereditary thrombophilia secondary to a homozygous mutation causing protein C deficiency, which is a rare thrombotic condition. Ocular ultrasonography revealed bilateral vitreous hemorrhaging linked to altered coagulation. One twin developed bilateral inguinal hernia and cryptorchidism. The novel concordance of Peters anomaly in these monozygotic twins sharing a mutation in PROC gene provides further evidence that this anomaly has a genetic basis. Hypoplasia of the optic nerves and optic chiasm, along with severe protein C deficiency and bilateral absence of the pupils, are associated comorbidities that have not previously been reported with this anomaly.

  16. Regional diagenetic patterns in the St. Peter Sandstone; implications for brine migration in the Illinois Basin

    USGS Publications Warehouse

    Pitman, Janet K.; Goldhaber, Martin B.; Spoetl, Christoph

    1997-01-01

    Diagenetic minerals and alteration patterns in the Ordovician St. Peter Sandstone, Illinois Basin, record varied hydrologic and chemical conditions during the basin?s long and complex geologic history. Major diagenetic events modifying the St. Peter Sandstone include (1) mechanical compaction, (2) early K-feldspar overgrowth and dolospar precipitation, (3) burial quartz, dolospar, anhydrite, and calcite cementation, and (4) carbonate-cement and K-feldspar grain dissolution. Radiometric age dates of authigenic K-feldspar and illite in combination with the reconstructed burial history of the St. Peter reveal that early-diagenetic K-feldspar and dolospar precipitated at shallow to moderate depths in the Devonian, whereas late-diagenetic quartz, dolospar, anhydrite, and calcite formed during deep burial in the Late Pennsylvanian to Early Permian. Stable-isotope geochemistry and fluid-inclusion paleothermometry suggest that burial cements precipitated from saline fluids over a wide temperature range. In the southern part of the basin, burial cements preserve a record of diagenetic effects that were in part controlled by fractures and hydrothermal-fluid circulation. Baroque dolospar cementation is the most significant of these effects.

  17. Impaired ADAMTS9 secretion: A potential mechanism for eye defects in Peters Plus Syndrome

    Peters Plus syndrome (PPS), a congenital disorder of glycosylation, results from recessive mutations affecting the glucosyltransferase B3GLCT, leading to congenital corneal opacity and diverse extra-ocular manifestations. Together with the fucosyltransferase POFUT2, B3GLCT adds Glucoseβ1-3Fucose disaccharide to a consensus sequence in thrombospondin type 1 repeats (TSRs) of several proteins. Which of these target proteins is functionally compromised in PPS is unknown. We report here that haploinsufficiency of murine Adamts9, encoding a secreted metalloproteinase with 15 TSRs, leads to congenital corneal opacity and Peters anomaly (persistent lens-cornea adhesion), which is a hallmark of PPS. Mass spectrometry of recombinant ADAMTS9 showed that 9 of 12 TSRs with the O-fucosylation consensus sequence carried the Glucoseβ1-3Fucose disaccharide and B3GLCT knockdown reduced ADAMTS9 secretion in HEK293F cells. Together, the genetic and biochemical findings imply a dosage-dependent role for ADAMTS9 in ocular morphogenesis. Reduced secretion of ADAMTS9 in the absence of B3GLCT is proposed as a mechanism of Peters anomaly in PPS. The functional link between ADAMTS9 and B3GLCT established here also provides credence to their recently reported association with age-related macular degeneration. PMID:27687499

    Tom Peters has been selected as the opening Keynote speaker at the National Association for Home Care and Hospice's Annual Meeting in Seattle, Washington on October 23-26, 2005. Peters has been described by the Los Angeles Times as the "father of the post-modern corporation." The New Yorker said, "In no small part, what American corporations have become is what Peters has encouraged them to be." Fortune called Tom Peters the top guru of management, and compares him to Ralph Waldo Emerson, Henry David Thoreau, Walt Whitman, and H.L. Mencken. The Economist tagged him the Uber-guru; and BusinessWeek's take on his "unconventional views" led them to label him "business's best friend and worst nightmare."

    The Peter Principle is a theory that provides a paradoxical explanation for job incompetence in a hierarchical organisation. It argues that should staff be competent at a given level, their competence may not be implicit at higher levels due to the differences in the skill set required. Furthering the work of a recent investigation into the Peter Principle utilising agent based simulation, this paper explores external factors upon varying promotion strategies to assess efficiency. Through additional elements of social networks and organisational thought, a more representative view of workplace interaction is presented. Results of the simulation found that although the Peter Principle affects efficiency, it may not be to the levels previously suggested. Furthermore promotion on merit provided the most favourable maximum and minimum efficiency margins, given the absence of clear evidence pertaining to the existence of the Peter Principle.

  20. Remelting and Remobilization in a Magmatic Arc: the St Peter Suite, South Australia

    Thermo-mechanical models of magmatic arcs suggest that intermittent intrusion of magma batches should lead to remelting and remobilization of earlier intrusive rocks as a result of fluctuations in temperature and water content. However, examples of remelting and remobilization of earlier intrusive rocks, formed during arc-building, are surprisingly rare. We investigate the evolution of magmatic rocks of the Palaeoproterozoic St Peter Suite, in the Gawler Craton, South Australia. This suite records multiple intrusions, magma hybridization, and the remelting and remobilization of these intrusions to form migmatites and newly-formed leucocratic magmas. In this paper we detail first how multiple magma batches interact with one another as liquids and mushes during syn-magmatic deformation phases, and then detail the nature of migmatites resulting from anatexis of these same magmatic rocks and the resulting channel ways that allowed for magma remobilization. LA-ICP/MS U/Pb zircon dating yielded crystallization ages of 1647×12 Ma for an early dioritic-to-granitic suite, and 1604×12 Ma for a later magmatic suite of broadly similar composition. Both these suites underwent anatectic events. Titanite from late-formed leucosomes found within D2 shear zones in the older suite, yielded SHRIMP U/Pb age of 1605×7 Ma, within error of the age of the younger suite. We therefore infer that intrusion, crystallization and remelting/remobilization of this younger suite of rocks occurred within 10-15 M.yr. We propose that the St Peter Suite exposures represent a frozen-in record of a continuous, multi-stage, repetitive process, common to the core of arcs where multiple magma intrusions drive multiple hybridization events and fluctuations in temperature and water-content trigger remelting and remobilization of the more fractionated sectors of earlier intrusive. Thus, the St Peter Suite record many of the key processes expected in arcs, including the prediction that early intrusive arc

    The article investigates the way in which Peter Mittelstaedt has been contributing to the philosophy of physics for half a century. It is shown that he pursues a path between rationalism and empiricism in the sense of Erhard Scheibe’s philosophy of the physicists. Starting from Kant’s a priori he gives a rational reconstruction of the conceptual revolutions of 20th century physics. The central topic of his philosophy of physics is the quest for semantic self-consistency, which for quantum mechanics is a hard nut to crack.

    The primary objective of this report is to determine the quantity and quality of existing forest habitat types on the 59,991-acre Peter T. Johnson Wildlife Mitigation Unit (WMU). Products from this effort include a description of the ecological condition, a map of habitat types, and an inventory of forest resources on the WMU lands. The purpose of this and other resource inventories (plant and wildlife) is to assess the current resources condition of the WMU and to provide necessary information to generate a long-term management for this area.

    There is increasing evidence that in the general population there are schizotypal traits and symptoms that can be measured psychometrically. Norms are reported for a new 21-item version of the Peters et al. Delusions Inventory (PDI; Peters et al. 1999b). The PDI, originally based on the Present State Examination, incorporates the multidimensionality of delusions by including measures of distress, preoccupation, and conviction. A total of 444 healthy individuals completed the 21-item PDI and two other questionnaires measuring florid delusions and social desirability. A subsample also filled out an in-depth schizotypal personality scale. Thirty-three deluded inpatients also completed the PDI. The PDI's psychometric properties confirmed that it remains a reliable and valid instrument to measure delusional ideation in the general population. Consistent with the 40-item PDI, it was normally distributed, no sex differences were found, and there was an inverse relationship with age. Individual items were endorsed by just over one in four healthy adults. Although the deluded sample scored significantly higher, the range of scores overlapped considerably, with 11 percent of healthy adults scoring higher than the mean of the deluded group. As with our previous findings, the two samples were differentiated by their ratings on the distress, preoccupation, and conviction scales. These results suggest that these dimensions may be more important than the content of belief alone for placing an individual on the continuum between normal and delusional thinking.

    The evolution of individual and total contents of capsaicinoids present in Peter peppers (Capsicum annuum var. annuum) at different ripening stages has been studied. Plants were grown in a glasshouse and the new peppers were marked in a temporal space of ten days. The extraction of capsaicinoids was performed by ultrasound-assisted extraction with MeOH. The capsaicinoids nordihydrocapsaicin (n-DHC), capsaicin, dihydrocapsaicin, homocapsaicin, and homodihydrocapsaicin were analyzed by ultraperformance liquid chromatography (UHPLC)-fluorescence and identified by UHPLC-Q-ToF-MS. The results indicate that the total capsaicinoids increase in a linear manner from the first point of harvest at ten days (0.283 mg/g FW) up to 90 days, at which point they reach a concentration of 1.301 mg/g FW. The evolution as a percentage of the individual capsaicinoids showed the initial predominance of capsaicin, dihydrocapsaicin, and n-DHC. Dihydrocapsaicin was the major capsaicinoid up to day 50 of maturation. After 50 days, capsaicin became the major capsaicinoid as the concentration of dihydrocapsaicin fell slightly. The time of harvest of Peter pepper based on the total capsaicinoids content should be performed as late as possible. In any case, harvesting should be performed before overripening of the fruit is observed.

    The goal of the Performance Evaluation Tests for Environmental Research (PETER) Program was to identify a set of measures of human capabilities for use in the study of environmental and other time-course effects. 114 measures studied in the PETER Program were evaluated and categorized into four groups based upon task stability and task definition. The Recommended category contained 30 measures that clearly obtained total stabilization and had an acceptable level of reliability efficiency. The Acceptable-But-Redundant category contained 15 measures. The 37 measures in the Marginal category, which included an inordinate number of slope and other derived measures, usually had desirable features which were outweighed by faults. The 32 measures in the Unacceptable category had either differential instability or weak reliability efficiency. It is our opinion that the 30 measures in the Recommended category should be given first consideration for environmental research applications. Further, it is recommended that information pertaining to preexperimental practice requirements and stabilized reliabilities should be utilized in repeated-measures environmental studies.

  8. Lunatic Asylum in the Workhouse: St Peter's Hospital, Bristol, 1698-1861.

    2017-04-01

    In recent years there has been growing acknowledgement of the place of workhouses within the range of institutional provision for mentally disordered people in nineteenth-century England. This article explores the situation in Bristol, where an entrenched workhouse-based model was retained for an extended period in the face of mounting external ideological and political pressures to provide a proper lunatic asylum. It signified a contest between the modernising, reformist inclinations of central state agencies and local bodies seeking to retain their freedom of action. The conflict exposed contrasting conceptions regarding the nature of services to which the insane poor were entitled. Bristol pioneered establishment of a central workhouse under the old Poor Law; 'St Peter's Hospital' was opened in 1698. As a multi-purpose welfare institution its clientele included 'lunatics' and 'idiots', for whom there was specific accommodation from before the 1760s. Despite an unhealthy city centre location and crowded, dilapidated buildings, the enterprising Bristol authorities secured St Peter's Hospital's designation as a county lunatic asylum in 1823. Its many deficiencies brought condemnation in the national survey of provision for the insane in 1844. In the period following the key lunacy legislation of 1845, the Home Office and Commissioners in Lunacy demanded the replacement of the putative lunatic asylum within Bristol's workhouse by a new borough asylum outside the city. The Bristol authorities resisted stoutly for several years, but were eventually forced to succumb and adopt the prescribed model of institutional care for the pauper insane.

    Purpose To report our findings in an infant with Peters anomaly type II whose retinopathy of prematurity (ROP) was treated with an anti-VEGF agent and surgeries. Case Report A male infant weighing 548 g was born prematurely at 23 weeks and 1 day with corneal opacity and shallow anterior chambers in both eyes. At the postmenstrual age of 35 weeks and 3 days, the infant was tentatively diagnosed with stage 3 ROP because of a dilated tunica vasculosa lentis and ultrasonographic findings. The boy was treated with bilateral intravitreal injections of bevacizumab (IVB) because laser photocoagulation of the retina could not be performed due to the corneal opacity. The retina in the right eye detached 3 times, namely 5 days, 16 days, and 7 months after the IVB; encircling the scleral buckle and a vitrectomy with endolaser photocoagulation were therefore required. In his left eye, the retina was reattached after the initial IVB, and no additional treatment was required. ROP was not reactivated in both eyes until the last examination at the age of 2 years and 6 months. Conclusions Our results showed that IVB is a useful treatment for ROP in patients with Peters anomaly. However, a retinal detachment can be a complication after IVB. The optimal timing of IVB for ROP in infants with hazy media needs to be determined. PMID:25408672

    The Australian bioethicist Peter Singer has presented an intriguing argument for the opinion that it is quite proper (morally) to deem the lives of certain individuals not worth living and so to kill them. The argument is based on the alleged analogy between the ordinary clinical judgement that a life with a broken leg is worse than a life with an intact leg (other things being equal), and that the broken leg therefore ought to be mended, on the one hand, and the judgement that the lives of some individuals, for example, severely disabled infants, are not worth living and therefore ought to be terminated, on the other. In the present article it is argued that Singer's argument is flawed, intellectually and/or ethically. PMID:7776346

The heart of the FOOT experiment is an instrumented suit called the Lower Extremity Monitoring Suit (LEMS). This customized garment is a pair of Lycra cycling tights incorporating 20 carefully placed sensors and the associated wiring control units, and amplifiers. LEMS enables the electrical activity of the muscles, the angular motions of the hip, knee, and ankle joints, and the force under both feet to be measured continuously. Measurements are also made on the arm muscles. Information from the sensors can be recorded up to 14 hours on a small, wearable computer.

    The debate over surgical abortion is certainly one of the most divisive in ethical discourse and for many it seems interminable. However, this paper argues that a primary reason for this is confusion with regard to what issues are actually under dispute. When looking at an entrenched and articulate figure on one side of the debate, Peter Singer, and comparing his views with those of his opponents, one finds that the disputed issue is actually quite a narrow one: the moral status of potential persons. Finding this common ground clears the conceptual space for a fruitful argument: the thesis of which is that most, including Singer, who argue that potential persons do not have full personal moral status fail to make the necessary distinction between natural potential (which confers moral status) and practical potential (which admittedly does not).

  15. Sir Peter Medawar: science, creativity and the popularization of Karl Popper

    2013-01-01

    Sir Peter Medawar was respected by scientists and literati alike. It was perhaps not surprising, then, that he would choose to involve himself in the ‘two cultures’ debate of 1959 and beyond. The focus of his intervention was the philosophy of Sir Karl Popper. However, Medawar's Popper was not the guru of falsification familiar from philosophy textbooks. Medawar's distinctive interpretation of Popper treated him instead as the source of insights into the role of creativity and imagination in scientific inquiry. This paper traces the context for Medawar's adoption of Popperian philosophy, together with its application before the debate. It then examines, within the context of the debate itself, the way in which Medawar attempted to reconcile scientific inquiry with literary practice. Medawar became increasingly convinced that not only was induction epistemologically unsound, but it was also damaging to the public role of the scientist. His construction of Popperianism would, he envisaged, provide a worthy alternative for scientists’ self-image.

    Peter Becker was a German neurologist who helped classify the muscular dystrophies, and described Becker muscular dystrophy and Becker myotonia. His involvement in National Socialism began in 1933, when he was compelled by his peers to join the SA (brown shirts). He later joined the Nazi party, the Nazi Doctors Association, and the Nazi Lecturers' Association. He renewed his SA membership to maintain his position at a genetics institute. Colleagues stated postwar that he was not an active Nazi, and he was de-Nazified in 1947, able to continue his career. Later, Becker admitted to most, but not all, of his Nazi memberships in his autobiography, and wrote 2 books exploring the origins of Nazism and racial hygiene. The "neurologic court of opinion" must weigh in on how we should best remember Becker, and at the very least, we as neurologists must learn the dangers of career opportunism at any cost.

    This commentary is dedicated to the memory of Peter J. Batten, MD. He was a public health physician, a psychiatrist, and a medical examiner who spent his entire career in Salem, the capital of the State of Oregon. Salem was a unique place to work because, early in the history of Oregon, the state elected to build all of its original public institutions in the environs of the city. As the county medical examiner, Dr. Batten reviewed all questionable deaths that occurred within the county and in particular within the public institutions. Many of his findings were subsequently published, and these reports influenced the direction of mental health policy in these same institutions. He also used his position as county medical examiner to examine deaths in road rage incidents and those occurring at railroad crossings in Salem. The commentary also emphasizes the benefits of collaboration within the forensic sciences.

    As President Jimmy Carter's advisor for health issues, Peter Bourne promoted a rational and comprehensive drug strategy that combined new supply-side efforts to prevent drug use with previously established demand-side addiction treatment programs. Using a public health ethic that allowed the impact of substances on overall population health to guide drug control, Bourne advocated for marijuana decriminalization as well as increased regulations for barbiturates. A hostile political climate, a series of rumors, and pressure from both drug legalizers and prohibitionists caused Bourne to resign in disgrace in 1978. We argue that Bourne's critics used his own public health framework to challenge him, describe the health critiques that contributed to Bourne's resignation, and present the story of his departure as a cautionary tale for today's drug policy reformers.

    Peter Anthony Motteux (1663-1718), a Huguenot refugee in London, established a literary reputation by completing Sir Thomas Urquhart's translation of Rabelais' Gargantua and Pantagruel, then Cervantes' Don Quixote. He later became an import-export merchant. On his 55th birthday he donned his scarlet cloak and went out on the town. He picked up a prostitute and after some dalliance returned to her bordello. Shortly thereafter he was found dead, although the evidence is that he was in good health when he arrived. Literary evidence is that he died from assisted erotic asphyxia, a variant of autoerotic asphyxia, cf. the case of Frantisek Koczwara (Am J Forensic Med Pathol 5:145-149, 1984.)

Writers may still implicitly presuppose a concept of care drawn from the Judaeo-Christian tradition but without explicit recourse to its moral basis nursing is left rudderless and potentially without purpose.

We prove it is the only (up to isomorphism) supergroup, which is a real form of (C 1 | 1) × with reduced Lie group S1, and a link with SUSY structures on C 1 | 1 is established. We describe a large family of complex semisimple representations of S 1 | 1 and we show that any S 1 | 1-representation whose weights are all nonzero is a direct sum of members of our family. We also compute the matrix elements of the members of this family and we give a proof of the Peter-Weyl theorem for S 1 | 1.

Locations for all samples are in Universal Transverse Mercator (UTM) coordinates. Brie[ descriptions of rock samples are also included. Rocks analysed are mostly sandstone. Samples of hematitic sandstone of the Rose Hill Formation and limonite-cemented sandstone of the Rocky Gap Sandstone contain high values of iron; these rocks are submarginal iron resources. Some of the same iron-rich samples have a little more barium, copper, cobalt, lead, silver, and/or zinc then average sandstone, but they do not suggest the presence of economic deposits of these metals. No other obviously anomalous values related to mineralized rock are present in the data.

    The acute toxicity of heavy metals in combination to the common guppy has been reported. Information on the combined effects of chromium and nickel to fish is rather scarce. Toxicity of nickel and chromium to fish is generally low. These two elements are usually less toxic than silver, cadmium, copper and thallium; depending on test conditions, these may also be less hazardous than zinc, lead and arsenic. The present study was undertaken to investigate the acute toxicity of Ni and Cr singly and the toxic interaction of these two metal ions on survival of the common guppy, Poecilia reticulata (Peters). This species was selected for static bioassays because it can be easily cultured and raised under laboratory conditions through a complete life cycle, and it is one of the most common fish used for laboratory toxicity studies.

    The St. Peter Sandstone in the Michigan basin subsurface is rapidly becoming a major exploration target for natural gas. This reservoir was first proven with the successful completion of the Dart-Edwards 7-36 (Falmouth field, Missaukee County, Michigan) in 1981. Fifteen fields now are known, with a maximum of three producing wells in any one field. The production from these wells ranges from 1 to more than 10 MMCFGD on choke, with light-gravity condensate production of up to 450 b/d. Depth to the producing intervals ranges from about 7000 ft to more than 11,000 ft. The St. Peter Sandstone is an amalgamated stack of shoreface and shelf sequences more than 1100 ft in thickness in the basin center and thinning to zero at the basin margins. Sandstone composition varies from quartzarenite in the coarser sizes to subarkose and arkose in the finer sizes. Thin salty/shaly lithologies and dolomite-cemented sandstone intervals separate the porous sandstone packages. Two major lithofacies are recognized in the basin: a coarse-grained, well-sorted quartzarenite with various current laminations and a fine-grained, more poorly sorted subarkose and arkose with abundant bioturbation and distinct vertical and horizontal burrows. Reservoir quality is influenced by original depositional and diagenetic fabrics, but there is inversion of permeability and porosity with respect to primary textures in the major lithofacies. The initially highly porous and permeable, well-sorted, coarser facies is now tightly cemented with syntaxial quartz cement, resulting in a low-permeability, poor quality reservoir. The more poorly sorted, finer facies with initially lower permeabilities did not receive significant fluid flux until it passed below the zone of quartz cementation. This facies was cemented with carbonate which has subsequently dissolved to form a major secondary porosity reservoir.

    Asbestos crystallizes within rock formations undergoing intense deformation characterized by folding, faulting, shearing, and dilation. Some of these conditions have prevailed during formation of the taconite iron ore deposits in the eastern Mesabi Iron Range of Minnesota. This range includes the Peter Mitchell Taconite Mine at Babbitt, Minnesota. The mine pit is over 8 miles long, up to 1 mile wide. Fifty three samples were collected from 30 sites within areas of the pit where faulting, shearing and folding occur and where fibrous minerals might occur. Eight samples from seven collecting sites contain significant amounts of ferroactinolite amphibole that is partially to completely altered to fibrous ferroactinolite. Two samples from two other sites contain ferroactinolite degraded to ropy masses of fibers consisting mostly of ferrian sepiolite as defined by X-ray diffraction and TEM and SEM X-ray spectral analysis. Samples from five other sites contain unaltered amphiboles, however some of these samples also contain a very small number of fiber bundles composed of mixtures of grunerite, ferroactinolite, and ferrian sepiolite. It is proposed that the alteration of the amphiboles was caused by reaction with water-rich acidic fluids that moved through the mine faults and shear zones. The fibrous amphiboles and ferrian sepiolite collected at the Peter Mitchell Mine composes a tiny fraction of one percent of the total rock mass of this taconite deposit; an even a smaller amount of these mineral fragments enter the ambient air during mining and milling. These fibrous minerals thus do not present a significant health hazard to the miners nor to those non-occupationally exposed. No asbestos of any type was found in the mine pit.

  9. Remelting and Remobilization in a Magmatic Arc: the St Peter Suite, South Australia

    Symington, Neil; Weinberg, Roberto; Hasalová, Pavlina

    2014-05-01

    Thermo-mechanical models of magmatic arcs suggest that intermittent intrusion of magma batches should lead to remelting and remobilization of earlier intrusive rocks as a result of fluctuations in temperature and water content. However, examples of remelting and remobilization of earlier intrusive rocks, formed during arc-building, are surprisingly rare. We investigate the evolution of magmatic rocks of the Palaeoproterozoic St Peter Suite, in the Gawler Craton, South Australia. This suite records multiple intrusions, magma hybridization, and the remelting and remobilization of these intrusions to form migmatites and newly-formed leucocratic magmas. In this paper we detail first how multiple magma batches interact with one another as liquids and mushes during syn-magmatic deformation phases, and then detail the nature of migmatites resulting from anatexis of these same magmatic rocks and the resulting channel ways that allowed for magma remobilization. LA-ICP/MS U/Pb zircon dating yielded crystallization ages of 1647±12 Ma for an early diorite-to-granite suite, and 1604±12 Ma for a later magmatic suite of broadly similar composition. Both these suites underwent anatectic events. Titanite from late-formed leucosomes found within D2 shear zones in the older suite, yielded SHRIMP U/Pb age of 1605±7 Ma, within error of the age of the younger suite. We therefore infer that intrusion, crystallization and remelting/remobilization of this younger suite of rocks occurred within 10-15 M.yr. Thus, the St Peter Suite exposures record many of the key processes expected in arcs, including the prediction that early intrusive arc rocks remelt to form younger more fractionated magmas.

  7. Utilization of the St. Peter Sandstone in the Illinois Basin for CO2 Sequestration

    SciTech Connect

    Will, Robert; Smith, Valerie; Leetaru, Hannes

    2014-09-30

    This project is part of a larger project co-funded by the United States Department of Energy (US DOE) under cooperative agreement DE-FE0002068 from 12/08/2009 through 9/31/2014. The study is to evaluate the potential of formations within the Cambro-Ordovician strata above the Mt. Simon Sandstone as potential targets for carbon dioxide (CO2) sequestration in the Illinois and Michigan Basins. This report evaluates the potential injectivity of the Ordovician St. Peter Sandstone. The evaluation of this formation was accomplished using wireline data, core data, pressure data, and seismic data acquired through funding in this project as well as existing data from two additional, separately funded projects: the US DOE funded Illinois Basin – Decatur Project (IBDP) being conducted by the Midwest Geological Sequestration Consortium (MGSC) in Macon County, Illinois, and the Illinois Industrial Carbon Capture and Sequestration (ICCS) Project funded through the American Recovery and Reinvestment Act (ARRA), which received a phase two award from DOE. This study addresses the question of whether or not the St. Peter Sandstone may serve as a suitable target for CO2 sequestration at locations within the Illinois Basin where it lies at greater depths (below the underground source of drinking water (USDW)) than at the IBDP site. The work performed included numerous improvements to the existing St. Peter reservoir model created in 2010. Model size and spatial resolution were increased resulting in a 3 fold increase in the number of model cells. Seismic data was utilized to inform spatial porosity distribution and an extensive core database was used to develop porosity-permeability relationships. The analysis involved a Base Model representative of the St. Peter at “in-situ” conditions, followed by the creation of two hypothetical models at in-situ + 1,000 feet (ft.) (300 m) and in-situ + 2,000 ft. (600 m) depths through systematic depthdependent adjustment of the Base Model

    The four principal HL-10 pilots are seen here with the lifting body aircraft. They are, left to right; Air Force Major Jerauld R. Gentry, Air Force test pilot Peter Hoag, and NASA pilots John A. Manke and Bill Dana. All are wearing the pressure suits needed for flying above 50,000 feet. The HL-10 was one of five heavyweight lifting-body designs flown at NASA's Flight Research Center (FRC--later Dryden Flight Research Center), Edwards, California, from July 1966 to November 1975 to study and validate the concept of safely maneuvering and landing a low lift-over-drag vehicle designed for reentry from space. Northrop Corporation built the HL-10 and M2-F2, the first two of the fleet of 'heavy' lifting bodies flown by the NASA Flight Research Center. The contract for construction of the HL-10 and the M2-F2 was $1.8 million. 'HL' stands for horizontal landing, and '10' refers to the tenth design studied by engineers at NASA's Langley Research Center, Hampton, Va. After delivery to NASA in January 1966, the HL-10 made its first flight on Dec. 22, 1966, with research pilot Bruce Peterson in the cockpit. Although an XLR-11 rocket engine was installed in the vehicle, the first 11 drop flights from the B-52 launch aircraft were powerless glide flights to assess handling qualities, stability, and control. In the end, the HL-10 was judged to be the best handling of the three original heavy-weight lifting bodies (M2-F2/F3, HL-10, X-24A). The HL-10 was flown 37 times during the lifting body research program and logged the highest altitude and fastest speed in the Lifting Body program. On Feb. 18, 1970, Air Force test pilot Peter Hoag piloted the HL-10 to Mach 1.86 (1,228 mph). Nine days later, NASA pilot Bill Dana flew the vehicle to 90,030 feet, which became the highest altitude reached in the program. Some new and different lessons were learned through the successful flight testing of the HL-10. These lessons, when combined with information from it's sister ship, the M2-F2/F3

    We explored the psychometric properties of the Korean version of the Peters et al. delusions inventory-21 (PDI-21) and evaluated the item characteristics of the PDI-21 compared with the Magical Ideation Scale (MIS) in Korean community adolescents. Survey participants comprised 310 Year 10 students who were assessed with the following instruments: the PDI-21, the MIS, the Schizotypal Personality Scale (STA) and the symptom checklist-90-R (SCL-90-R). The item characteristics of the PDI-21 and MIS were also explored using item response theory (IRT). The PDI-21 exhibited good internal consistency and demonstrated significant correlations with the MIS, STA and all subscale scores of the SCL-90-R, indicating psychological distress in adolescents with high PDI-21 scores. We also found through IRT analysis that the PDI-21 provides more information at the lower range and the MIS at the higher range of delusion proneness. Our findings suggest that the PDI-21 is an effective and reliable self-report measure for assessment of delusion proneness and that the PDI-21 and the MIS may be used complementarily to assess a broad range of delusion proneness among community adolescents.

    Types of Rhyparochromidae (Hemiptera: Heteroptera: Lygaeoidea) species described by Carl Peter Thunberg, deposited in the Museum of Evolution (formerly Zoologiska Institut), Uppsala University, Uppsala, Sweden, were reexamined and the taxonomic and nomenclatural problems that existed among those species discussed and resolved as required. Lectotypes are designated for Cimex caffer Thunberg, 1784, Lygaeus ater Thunberg, 1822, Lygaeus biguttatus Thunberg, 1822, and Pendulinus guttatus Thunberg, 1825. The lectotype of Pendulinus (now Metochus) guttatus is designated as neotype of Pendulinus (now Metochus) uniguttatus Thunberg, 1822; as a result the former name becomes junior objective synonym of the latter. The following taxonomic changes are proposed: Lethaeus ater (Thunberg, 1822), new combination (from Lygaeus); Migdilybs biguttatus (Thunberg, 1822), new combination (from Lygaeus) = Migdilybs furcifer Hesse, 1925, new subjective synonym; Metochus uniguttatus (Thunberg, 1822) = Metochus bengalensis (Dallas, 1852), confirmed subjective synonym = Metochus yeh (Dohrn, 1860), confirmed subjective synonym; Raglius alboacuminatus (Goeze, 1778) = Cimex caffer Thunberg, 1874, confirmed subjective synonym. Lethaeus barberi Slater, 1964 does not belong to Lethaeus Dallas, 1852 but currently it cannot be placed with confidence in any existing genus.

    Tetrahymena is a protozoan parasite, which infects guppy, Poecilia reticulata Peters, and causes substantial economical losses in commercial farms worldwide. Studies of guppy infected by Tetrahymena require standardized infection protocols. The LD50 for Tetrahymena infection of guppies by intraperitoneal (IP) injection was calibrated, and the level obtained was 946 parasites per fish. Guppy infection with Tetrahymena by immersion, imitating the natural route of infection via the integument, was studied under normal or stress conditions. Exposure to cold and netting (CNI) and to cold only (CI) followed by immersion exposure to 10 000 Tetrahymena per mL resulted in 22.5% and 19.2% mortality, respectively, as compared to 14.2% and 10% in groups that were netted only (NI) or non-stressed (I). Histopathology revealed that immersion infection resulted in a systemic infection. Lysozyme levels, measured 3 weeks after infection, were significantly higher in the CNI group (288 μg per mg protein) compared with CI-, NI- and I-treated groups (94.5, 64 and 62.3 μg mg(-1), respectively). There was no evident parasite immobilization activity in body homogenates, suggesting no development of acquired immunity. Re-infection by IP injection revealed no increase in protection in any of the treatment groups, mortality range of 56.3-75%, higher than in the non-exposed control (40.6% mortality). © 2014 John Wiley & Sons Ltd.

    We present a few newly found old sunspot observations from the years AD 1708, 1709, and 1710, which were obtained by Peter Becker from Rostock, Germany. For 1709, Becker gave a detailed drawing: he observed a sunspot group made up of two spots on January 5, 6, and 7, and just one of the two spots was observed on January 8 and 9. We present his drawing and his explanatory text. We can measure the latitude and longitude of these two spots and estimate their sizes for all five days. While the spots and groups in 1708 and the spot on four of the five days in January 1709 were known before from other observers (e.g. Hoyt & Schatten 1998), the location of the spots in early January 1709 were not known before, so that they can now be considered in reconstructed butterfly diagrams. The sunspots detected by Becker on 1709 January 5 and 1710 September 10 were not known before at all, as the only observer known for those two dates, La Hire, did not detect that spot (group). We estimate new group sunspot numbers for the relevant days, months, and years. The time around 1708-1710 is important, because it documents the recovery of solar activity towards the end of the Maunder Grand Minimum. We also show two new spot observations from G. Kirch for 1708 September 13 and 14 as described in his letter to Wurzelbaur (dated Berlin AD 1708 December 19).

  14. The Quantum Logical Challenge: Peter Mittelstaedt's Contributions to Logic and Philosophy of Science

    NASA Astrophysics Data System (ADS)

    Beltrametti, E.; Dalla Chiara, M. L.; Giuntini, R.

    2017-04-01

    Peter Mittelstaedt's contributions to quantum logic and to the foundational problems of quantum theory have significantly realized the most authentic spirit of the International Quantum Structures Association: an original research about hard technical problems, which are often "entangled" with the emergence of important changes in our general world-conceptions. During a time where both the logical and the physical community often showed a skeptical attitude towards Birkhoff and von Neumann's quantum logic, Mittelstaedt brought into light the deeply innovating features of a quantum logical thinking that allows us to overcome some strong and unrealistic assumptions of classical logical arguments. Later on his intense research on the unsharp approach to quantum theory and to the measurement problem stimulated the increasing interest for unsharp forms of quantum logic, creating a fruitful interaction between the work of quantum logicians and of many-valued logicians. Mittelstaedt's general views about quantum logic and quantum theory seem to be inspired by a conjecture that is today more and more confirmed: there is something universal in the quantum theoretic formalism that goes beyond the limits of microphysics, giving rise to interesting applications to a number of different fields.

  15. Pescadillo homologue 1 and Peter Pan function during Xenopus laevis pronephros development.

    PubMed

    2011-10-01

    pes1 (pescadillo homologue 1) and ppan (Peter Pan) are multifunctional proteins involved in ribosome biogenesis, cell proliferation, apoptosis, cell migration and regulation of gene expression. Both proteins are required for early neural development in Xenopus laevis, as previously demonstrated. We show that the expression of both genes in the developing pronephros depends on wnt4 and fzd3 (frizzled homologue 3) function. Loss of pes1 or ppan by MO (morpholino oligonucleotide)-based knockdown approaches resulted in strong malformations during pronephric tubule formation. Defects were already notable during specification of pronephric progenitor cells, as shown by lhx1 expression. Moreover, we demonstrated that Xenopus pes1 and ppan interact physically and functionally and that pes1 and ppan can cross-rescue the loss of function phenotype of one another. Interference with rRNA synthesis, however, did not result in a similar early pronephros phenotype. These results demonstrate that pes1 and ppan are required for Xenopus pronephros development and indicate that their function in the pronephros is independent of their role in ribosome biosynthesis.

  16. Cloning and characterization of peter pan, a novel Drosophila gene required for larval growth.

    PubMed

    Migeon, J C; Garfinkel, M S; Edgar, B A

    1999-06-01

    We identified a new Drosophila gene, peter pan (ppan), in a screen for larval growth-defective mutants. ppan mutant larvae do not grow and show minimal DNA replication but can survive until well after their heterozygotic siblings have pupariated. We cloned the ppan gene by P-element plasmid rescue. ppan belongs to a highly conserved gene family that includes Saccharomyces cerevisiae SSF1 and SSF2, as well as Schizosaccharomyces pombe, Arabidopsis, Caenorhabditis elegans, mouse, and human homologues. Deletion of both SSF1 and SSF2 in yeast is lethal, and depletion of the gene products causes cell division arrest. Mosaic analysis of ppan mutant clones in Drosophila imaginal disks and ovaries demonstrates that ppan is cell autonomous and required for normal mitotic growth but is not absolutely required for general biosynthesis or DNA replication. Overexpression of the wild-type gene causes cell death and disrupts the normal development of adult structures. The ppan gene family appears to have an essential and evolutionarily conserved role in cell growth.

    2011-11-01

    Regarded as "America's first plastic surgeon," Dr John Peter Mettauer's professional life displays 3 fundamental keystones of plastic surgery: education, innovation, and practice. To fully appreciate the history of our plastic surgery, one must look beyond a purely factual recount of noteworthy actions performed decades ago. Fundamental principles that governed achievements of our predecessors remain applicable even today. Dr Mettauer thrived as a medical student under the influence of distinguished professors in medicine at the University of Pennsylvania. Later, he continued to propagate their basic tenets when he established his medical institute in 1837. Throughout his life, Dr Mettauer combined ingenuity with scientific inquiry to devise numerous unprecedented surgical techniques and instruments. He was a prolific writer and exquisitely documented his work in medical journals for the benefit of both contemporary and future surgeons. One of Dr Mettauer's momentous achievements in plastic surgery that displays his remarkable capabilities was his contributions to management of both simple and complicated cases of cleft palate. He was the first to describe relaxing lateral incisions for treating complete cleft palates and, incidentally, was the first to successfully treat this in America. He invariably replicated similar success in establishing techniques for treating a wide range of anatomic deformities. Cumulatively, Dr Mettauer's lifelong commitment and diligence have truly laid a foundation for the eventual progress and success in the field of plastic surgery.

Results of direct observations of cascading by autonomous mooring systems and repeated CTD surveys during winters of 2012-2014 have been presented here. The events of dense water, formed by cooling and brine rejection on the shelf during ice formation, approaches the shelf edge (100 m) have been registered every winter usually in February - March. However their duration has been varied interannually reflecting climatic changes. Only one episode of deep down slope cascading was registered by mooring at 1150 m. Its duration was only around 12 hours. These very transient events however resulted in a number of intrusions of colder, less saline, higher oxygen content and higher turbidity water detected by CTD casts observed down to 2000-2800 m indicating penetration of cascading down to the bottom of the slope and thus ventilation of the intermediate, deep and bottom waters of the Japan Sea. Depending on a severity of winter the intrusions formed by cascading water ventilate intermediate layers (winters of 2013-2014) or may penetrate down to the bottom layer (extremely cold winter 2001). In any case this ventilation mechanism is important to understand water mass transformation in the Japan Sea.

    Dendronereis spp. (Peters) (Nereididae) is a common polychaete in shrimp ponds built on intertidal land and is natural food for shrimp in traditionally managed ponds in Indonesia. White spot syndrome virus (WSSV), an important viral pathogen of the shrimp, can replicate in this polychaete (Desrina et al. 2013); therefore, it is a potential propagative vector for virus transmission. The major aim of this study was to determine whether WSSV can be transmitted from naturally infected Dendronereis spp. to specific pathogen-free (SPF) Pacific white shrimp Litopenaeus vannamei (Boone) through feeding. WSSV was detected in naturally infected Dendronereis spp. and Penaeus monodon Fabricius from a traditional shrimp pond, and the positive animals were used in the current experiment. WSSV-infected Dendronereis spp. and P. monodon in a pond had a point prevalence of 90% and 80%, respectively, as measured by PCR. WSSV was detected in the head, gills, blood and mid-body of Dendronereis spp. WSSV from naturally infected Dendronereis spp was transmitted to SPF L. vannamei and subsequently from this shrimp to new naïve-SPF L. vannamei to cause transient infection. Our findings support the contention that Dendronereis spp, upon feeding, can be a source of WSSV infection of shrimp in ponds. © 2014 John Wiley & Sons Ltd.

    Fenpyroximate (FP), an acaricide, is widely used in the prevention of acarids (mites) in fruit plant gardens. In this study, the acute toxic effects of different concentrations of FP were investigated using adult guppy (Poecilia reticulata Peters, 1859). Guppy adults were exposed to a range of FP concentrations (25, 50, 75, 100, 125, and 150 µg/L) during 48 h. Static method, which is one of the acute toxicity experiments, has been used in this study. According to probit analysis, the 48-h median lethal concentration (LC50) value of FP at 26°C was found to be 72.821 µg/L. Sublethal exposures were predetermined based on 48-h LC50 value. Guppies were exposed to low concentrations (15, 25, and 50 µg/L) of FP for 48 h. Signs of paralysis and behavior deformations were monitored every 12 h in a number of live and dead adults. Low concentrations of FP were also responsible for erratic swimming, loss of equilibrium, and being lethargic. Liver histology revealed several pathological damages including congestion, picnotic nucleus, sinusoidal dilatation, increase in melanomacrophagic centers, and endothelial degeneration. Finally, the toxicity test results provided 48-h LC50 value for FP, and low concentrations of FP can be highly detrimental to guppy adults with clear evidence of behavioral and histologic effects.

  1. "Pop" psychoanalysis, kitsch, and the "as if" theater: further notes on Peter Shaffer's Equus.

    PubMed

    Gifford, S

    1976-01-01

    This paper is intended as an examination of Dr. Stamm's (1975) paper and of Dr. Jules Glenn's discussion of Peter Shaffer's previous work. Its premise is the futility of subjecting Equus to a traditional psychoanalytic investigation, as a product of the playwright's unconscious, when the play represents a skillful, highly conscious use of analytic cliches to manipulate the audience. This phenomenon, however, and the play's great popularity prompt some reflections on the nature of kitsch, or false art, and its differences from authentic drama. The experience of kitsch can be identified when the spectator feels coerced by exaggerated, unconvincing theatrical devices, and fails to experience genuine empathy with the characters in a play. In the experience of authentic tragedy there is some element of voluntary surrender, of suspension of disbelief with full consent of will, as in the Aristotelian concept of catharsis. Shaffer's play is discussed as an illustration of this distinction and its relation to pseudoemotionality, the impostor syndrome, and the "as if" personality. In conclusion, the play's failure to evoke a genuine emotional response is explained by interpreting Equus as an "as if" tragedy.

    This article pays tribute to the seminal paper by Peter J. Lang (1977; this journal), "Imagery in Therapy: Information Processing Analysis of Fear." We review research and clinical practice developments in the past five decades with reference to key insights from Lang's theory and experimental work on emotional mental imagery. First, we summarize and recontextualize Lang's bio-informational theory of emotional mental imagery (1977, 1979) within contemporary theoretical developments on the function of mental imagery. Second, Lang's proposal that mental imagery can evoke emotional responses is evaluated by reviewing empirical evidence that mental imagery has a powerful impact on negative as well as positive emotions at neurophysiological and subjective levels. Third, we review contemporary cognitive and behavioral therapeutic practices that use mental imagery, and consider points of extension and departure from Lang's original investigation of mental imagery in fear-extinction behavior change. Fourth, Lang's experimental work on emotional imagery is revisited in light of contemporary research on emotional psychopathology-linked individual differences in mental imagery. Finally, key insights from Lang's experiments on training emotional response during imagery are discussed in relation to how specific techniques may be harnessed to enhance adaptive emotional mental imagery training in future research.

    The St. Peter Sandstone (Middle-late Ordovician) of the Michigan basin represents an approximately 10-m.y. interval of clastic deposition in an otherwise carbonate-dominated Ordovician succession. This interval, up to 320 m thick, also coincides with a change in basin configuration from the nearly circular depocenter of the underlying Shakopee Formation to an east-west elongate trough situated west to Saginaw Bay. Interpretation of well logs and core from throughout the basin indicates that the clastics are composed of 20-25 sequences upper shoreface to tidal-flat environments. The sequences are interbedded with heavily bioturbated, shaly, lower shoreface sandstones (1-14 m thick) and, in the central and southeastern parts of the basin, with carbonate shales, stromatolites, and oolitic grain-stones (2-39 m thick). The eastern and southeastern margins of the basin contain the thickest carbonate accumulations. Hydrocarbons fields are located over structural highs formed by reactivation of basement structures. Detailed comparison of well logs within field shows that sedimentary cycles thin over the structures as a result of the local reduction in the formation of accommodation space by syndepositional movements on the faults. The presence of thick carbonates along the southeastern margin of the basin is a result of the combination of distance form the clastic source and the episodic formation of accommodation space by syndepositional normal faulting along the basin margin.

    Wells currently provide all water supplies in the area. Most wells obtain enough water for individual household needs from unconsolidated, principally glacial and glacioalluvial deposits. In some places, however, wells must be drilled into the underlying bedrock to obtain adequate supplies. It may be possible to develop small community supplies--for individual trailer courts or subdivisions--in areas where yields of 20 gallons per minute or greater are reported for private, domestic wells. Peters Creek is a potential source of surface-water supply, but it would have to be treated to remove glacial silt during summer months. The chemical quality of both ground water and surface water in the area in generally acceptable for most uses. Foundation and excavation conditions, the potential for water pollution from onsite disposal of wastewater through septic tank systems, and the suitability of specific areas for certain types of development may be affected by the following factors: wetlands and areas of shallow ground water underlie about 30 percent of the study area; landslope exceeds 20 percent in about a third of the area; areas of fine-grained, low-permeability sediments are present locally; bedrock is within 25 feet of the land surface in about a third of the area.

    In the 19th century, several astronomers made observations of sunspots, recording their positions and sometimes their areas. These observations were published in the form of extensive tables, but have been unhelpful until now. Three of these observers were Richard C. Carrington, Christian H.F. Peters and Warren de la Rue (and their respective collaborators). They published, in various articles, the data corresponding to 26 641 sunspot positions (Carrington, Peters and de la Rue registered 4900, 14040 and 7701 sunspot positions, respectively). In this paper we present a translation of more than 400 pages of their printed numerical tables into a machine readable format, including an initial analysis targeted at detecting possible mistakes in the reading or in the original transcription. The observations carried out by these three astronomers have been made available at the Centre de Donées Astronomiques de Strasbourg (http://cdsarc.u-strasbg.fr/cgi-bin/VizieR?-source=VI/138).

    A habitat based assessment was conducted of the US Army Corps of Engineers' Green Peter-Foster Dam and Reservoir Project on the Middle Fork Santiam River, Oregon, to determine losses or gains resulting from the development and operation of the hydroelectric related components of the project. Preconstruction, postconstruction, and recent vegetation cover types at the project site were mapped based on aerial photographs from 1955, 1972, and 1979, respectively. Vegetation cover types were identified within the affected area and acreages of each type at each period were determined. Eleven wildlife target species were selected to represent a cross-section of species groups affected by the project. An interagency team evaluated the suitability of the habitat to support the target species at each time period. An evaluation procedure which accounted for both the quantity and quality of habitat was used to aid in assessing impacts resulting from the project. The Green Peter-Foster Project extensively altered or affected 7873 acres of land and river in the Santiam River drainage. Impacts to wildlife centered around the loss of 1429 acres of grass-forb vegetation, 768 acres of shrubland, and 717 acres of open conifer forest cover types. Impacts resulting from the Green Peter-Foster Project included the loss of critical winter range for black-tailed deer and Roosevelt elk, and the loss of year-round habitat for deer, upland game birds, river otter, beaver, pileated woodpecker, and many other wildlife species. Bald eagle and osprey were benefited by an increase in foraging habitat. The potential of the affected area to support wildlife was greatly altered as a result of the Green Peter-Foster Project. Losses or gains in the potential of the habitat to support wildlife will exist over the life of the project.

    The German organic chemist Johann Peter Griess (1829–88), who first developed the diazotization of aryl amines (the key reaction in the synthesis of the azo dyes), and a major figure in the formation of the modern dye industry, worked for more than a quarter of a century at the brewery of Samuel Allsopp and Sons in Burton upon Trent, which, owing to the presence of several notable figures and an increase in the scientific approach to brewing, became a significant centre of scientific enquiry in the 1870s and 1880s. Unlike the other Burton brewing chemists, Griess paralleled his work at the brewery with significant contributions to the chemistry of synthetic dyes, managing to keep the two activities separate—to the extent that some of his inventions in dye chemistry were filed as patents on behalf of the German dye company BASF, without the involvement of Allsopp's. This seemingly unlikely situation can be explained partly by the very different attitudes to patent protection in Britain and in Germany combined with an apparent indifference to the significant business opportunity that the presence of a leading dye chemist presented to Allsopp's. Although his work for the brewery remained largely proprietary, Griess's discoveries in dye chemistry were exploited by the German dye industry, which quickly outpaced its British counterpart. One less well-known connection between brewing and synthetic dyes, and one that may further explain Allsopp's attitude, is the use of synthetic dyes in identifying microorganisms—the perennial preoccupation of brewers seeking to maintain yield and quality. Developments of Griess's original work continue to be applied to many areas of science and technology.

  9. A dissection of the chapter "Tools for Research" in Peter Singer's Animal Liberation.

    The book Animal Liberation, by philosopher Peter Singer, is frequently referred to as the bible of the animal liberation/rights movement(ALARM). Thus, Singer is regarded as a major moral standard-bearer of the ALARM. Some have suggested that his book provides "intellectual rigor" to the moral arguments for animals' equality with humans, which had previously been based largely on emotionalism and sentimentality. We have analyzed the contents of the chapter "Tools for Research" which criticizes the use of animals in biomedical research as well as for drug and product-safety testing. In order to discredit these practices, Singer "documents" his arguments with 138 "notes", some of which are to the same reference and others of which contain multiple references. Of the 132 difference references, we attempted to verify the accuracy of 49 of them. Of these, 16 (33%) were inaccurate or we could not find. In addition, Singer mischaracterizes the cited studies in various ways. He quotes selectively and out of context from numerous research projects. He never mentions the objectives of these projects, except occasionally when, in our opinion, he distorts or trivializes them. Singer also cites supposedly damning "evidence" published by other antivivisectionists, even though this "evidence" has been refuted in the literature. Singer supposedly embraces utilitarianism, a philosophy which holds that the harm done by a practice should be balanced against the gain realized from it. However, he makes virtually no attempt to consider objectively the benefits that have been realized from animal-based medical research and he greatly exaggerates the costs. To him, animal research is "all pain and no gain." We believe that Singer's moral arguments for animal equality are not convincing. The lack of objectivity and the reliance upon distortion and selective quotation that characterize Singer's "scholarship" are surprising when one considers that he presents himself as an ethicist and

  10. Unique Grain-Scale Behavior Preceding Fracture-Like Breakouts in St. Peter Sandstone

    2001-12-01

    We are conducting tests in St. Peter sandstone (average grain size 0.25 mm, cementation by sutured grain contact) of various porosities (ranging from 11 to 19%), in which drilling of vertical holes into 130 x 130 x 180 mm blocks subjected to pre-determined true triaxial far-field stresses (σ H!=qσ h!=qσ v) induce borehole instability resulting in breakouts. Unlike the typical dog-eared breakouts found in other rock types, and regardless of porosity, these are thin and tabular, i.e. fracture-like, can extend for lengths reaching several borehole diameters in the direction of the least horizontal stress σ h, and retain constant widths of 10 to 15 grain diameters throughout. Analysis of the damage zone ahead of the breakout tip reveals two distinct modes of micromechanical behavior. In the higher porosity (n=15-19%) sandstone, breakouts are preceded by the development of a narrow band of debonded, but mostly intact grains, suggesting that failure is occurring at grain sutures, and is therefore non-dilatant. However, in the lower porosity (n=11-15%) rock, breakouts occur within a long narrow zone of crushed grains caused by extensive failure of sutured grain contacts and the grains themselves. The breakouts in both cases appear to result from the formation of compaction bands that are emptied by the circulating fluid. The distinct characters of the failed zones can be related to the respective grain sutures. The matrix of the higher-porosity samples contains small areas of grain-to-grain sutured contact; this contact is severed at relatively low stress levels, yielding debonded but intact grains. In contrast, the lower porosity samples reveal large sutured grain contacts relative to grain size. The stronger matrix requires a higher stress to initiate debonding, a level that is also sufficient to crush the grains within the compaction band that develops ahead of the fracture-like breakout tip.

    Introduction The emergence of multi-drug resistant tuberculosis (MDR-TB) has become a major public health concern that threatens advances made in global TB control efforts. Though the problem is prevalent, it did not receive major attention to generate supportive evidence for the prevention and control of MDR-TB. The aim of this study was to identify predictors of MDR-TB in a national TB referral centre in Ethiopia. Methods An unmatched, case-control study was conducted at St. Peter Hospital to assess risk factors associated with MDR-TB. The study included 103 culture proven, MDR-TB patients referred to the hospital during the study period (cases) and 103 randomly-selected TB patients with confirmed TB who turned negative after treatment (controls). Regressions analyses were used to determine the association of variables. Results The mean age among cases and controls was 30.5 (±9.26) and 34.73 (±11.28) years, respectively. The likelihood of having MDR-TB was 20.3 times higher among those who had a any previous history of TB treatment (AOR=20.3 [CI 5.13, 80.58]), 15.7 times higher among those who had TB more than once (AOR=15.7 [CI 4.18, 58.71]) compared those who had once, 6.8 times higher among those who had pulmonary TB (AOR=6.8 [CI 1.16, 40.17]) and 16.1 times higher for those who had experienced treatment with a Category II regimen (AOR=16.1 [CI 2.40, 108.56]). HIV infection was less common among cases than controls. Conclusion This study concluded that special attention should be given to patients with a history of the following: TB more than once, presence of pulmonary TB, and used a Category II treatment regimen, as these were all determining factors for MDR-TB. Thus, this study urges the development and implementation of well-planned and integrated strategies for MDR-TB control and prevention in Ethiopia. PMID:28439330

    A new fossil fauna has been discovered from a recently recognized shale unit within the middle Ordovician St. Peter Formation in northeast Iowa. It contains a variety of invertebrates and vertebrates, including soft body tissues, impressions, and 3-dimensionalpreservations. The exceptional preservation reveals a new Konservat-Lagerstätte, the Winneshiek Lagerstätte, and opens a unique window into the community that inhabited the margins of the Laurentian cratonic seaway during Middle Ordovician transgression. Among the fossils, several conodont assemblages, including the apparatus of enigmatic coleodontids, are preserved. Some conodont assemblages associated with soft body tissues are particularly noteworthy.

    The Saint Peter and Saint Paul Archipelago in the central tropical Atlantic, is an important ground of whale sharks that are commonly sighted throughout the year close to the fishing boats in the adjacencies of the islands. In sightings reported between February 2000 and November 2005, the lengths of the individuals ranged between 1.8 to 14.0 m. The causes of these concentrations in the archipelago are still unclear, once there are no upwellings and plankton concentrations for feeding, and no reproductive activities were reported. Nevertheless, they could be associated to the spawning period of the abundant flying fishes, mainly in the first semester, when sightings were more frequent.

    A valuable mariculture object, the Japanese scallop Mizuhopecten (= Patinopevten) yessoensis (Jay), after six hours long transportation by air and sowing on the bottom is fouled greater by epi- and endolythical organisms than the members of the native population. It is likely that the fouling negatively affects the specimens, those that were the largest before the sowing at the bottom were not found among those that reached puberty. The results of the effects of the endolythic polychaete Polydora brevipalpa and the barnacle Hesperibalanus hesperius on the growth rate of the Japanese scallop cultivated on the bottom of Peter the Great Bay (Sea of Japan) are provided in this paper.

    Security is a vital issue in communication and storage of the images and encryption is one of the ways to ensure the security. This paper proposes an efficient image encryption scheme based on a Peter De Jong chaotic map and a RC4 stream cipher. A Peter De Jong map is employed to determine the initial keys for the RC4 stream generator and also during permutation stage. The RC4 stream generator is utilized to generate the pseudo random numbers for the pixel value rotation and diffusion operations. Each encryption round is comprised of three stages: permutation, pixel value rotation and diffusion. The permutation is based on scrambling the rows and columns, in addition, circular rotations of the rows and columns in alternate orientations. The second stage circularly rotates each and every pixel value by utilizing M × N pseudo random numbers. The last stage carries out the diffusion twice by scanning the image in two different ways. Each of the two diffusions accomplishes the diffusion in two orientations (forward and backward) with two previously diffused pixels and two pseudo random numbers. The security and performance of the proposed method is assessed thoroughly by using key space, statistical, differential, entropy and performance analysis. Moreover, two rounds of the call to the encrypt function provide the sufficient security. The experimental results show that the proposed encryption scheme is computationally fast with high security.

    John P Peters is considered one of the founders of modern clinical chemistry. In more than 200 research articles, he brought clinical biochemistry to the bedside, advancing the use of laboratory medicine in diagnosis and disease management. His two-volume landmark textbook Quantitative Clinical Chemistry, coauthored with Donald Dexter van Slyke (1883-1971) and released in 1931-1932, defined clinical chemistry as a distinct professional discipline within medicine. A three-volume revision was begun in 1937. Peters took on the task of revising Volumes I and II but never finished Volume II. His outspoken public advocacy for social reform, world peace, and universal health care made him a target in the era of McCarthyism. Three times between 1949 and 1953 he was brought before the Loyalty Review Board with charges of being a communist and a sympathetic supporter of subversive organizations. According to his family, the turmoil of the McCarthyism persecution shortened his life and prevented him from completing the one thing he wanted to do in his professional life, finish the revision of his landmark clinical chemistry textbook.

    A Child Analysis with Anna Freud, a collection of Anna Freud's detailed case notes of her treatment of the young Peter Heller between 1929 and 1932, was first published in English in 1990. Not only does this work give us direct access to Anna Freud's ways of thinking and working at a crucial period in the early history of child analysis; it is also one of the few records of an adult reflecting in depth on the experience of being in analysis as a child. Yet to date this work has received little attention in the psychoanalytic literature. In an attempt to redress this neglect, the Heller case study is placed in the context of Anna Freud's emerging ideas about child analysis. In particular, its significance in the development of her psychoanalytic thinking is investigated in the light of her 1927 book, The Technique of Child Analysis.

    The 1615 painting of Venus at a Mirror by Peter Paul Rubens is considered a powerful example of the Flemish Baroque movement. Recently it has been identified that the Venus character in the image has a goitre, however on studying the image further, I note dermato-pathology in another of the painting's main characters; the dark-skinned female typically described as the Venus' maidservant who clearly demonstrates patches of skin pigment loss on her face and neck with a concurrent streak of white hair. Together these suggest the underlying diagnosis of vitiligo. There is also a goitre in this individual suggesting thyroid disease. This new finding may offer additional insight into the historical epidemiology of disease in northern Europe but also offers further understanding of the method, origin, and pathological associations of this prominent painting from a genius artist. © 2017 Wiley Periodicals, Inc.

  2. The Solar Rotation in the Period 1853 - 1870 from the Sunspot Catalogues of Carrington, Peters, and de la Rue

    R.C. Carrington, C.H.F. Peters, and W. de la Rue observed the sunspots in the second half of the nineteenth century, determining their heliographic positions between 1853 and 1870, before the solar program of the Royal Greenwich Observatory was established. The large tables of sunspot positions included in the catalogues published by these observers have recently been converted into a machine-readable format. The present work analyses these data by calculating the sunspot group velocities for each observer. The results are then fitted with a differential-rotation law to compare the data of the three observers with each other and with the results published by others. Finally, we study the possible relationship between the sunspot-group areas as determined by de la Rue and the corresponding sunspot-group velocities.

Lake Athabasca experienced a 21.2% decline in streamflow input between 1960 and 2010 that has led to a marked decline in its water levels in recent decades. A reassessment of trends in naturalized Lake Athabasca water levels shows insignificant changes from our previous findings reported in Rasouli et al. (2013), and hence our previous conclusions remain unchanged. The reply closes with recommendations for future research to minimize uncertainties in historical assessments of trends in Lake Athabasca water levels and to better project its future water levels driven by climate change and anthropogenic activities in the Athabasca Lake basin.

    Eleven expeditions were undertaken to the Saint Peter and Saint Paul Archipelago to study the reproductive biology of Grapsus grapsus, providing additional information on limb mutilation and carapace colour. MATURE software was used to estimate morphological maturity, while gonadal analyses were conducted to estimate physiological maturity. The puberty moult took place at larger size in males (51.4 mm of carapace length) than in females (33.8 mm), while physiological maturity occurred at a similar size in males (38.4 mm) and in females (33.4 mm). Above 50 mm, the proportion of red males increased in the population, indicating that functional maturity is also related to colour pattern. Small habitat and high local population density contributed to the high rate of cannibalism. The low diversity of food items, absence of predators of large crabs and high geographic isolation are the determinants of unique behavioural and biological characteristics observed in the G. grapsus population.

    As President Jimmy Carter’s advisor for health issues, Peter Bourne promoted a rational and comprehensive drug strategy that combined new supply-side efforts to prevent drug use with previously established demand-side addiction treatment programs. Using a public health ethic that allowed the impact of substances on overall population health to guide drug control, Bourne advocated for marijuana decriminalization as well as increased regulations for barbiturates. A hostile political climate, a series of rumors, and pressure from both drug legalizers and prohibitionists caused Bourne to resign in disgrace in 1978. We argue that Bourne’s critics used his own public health framework to challenge him, describe the health critiques that contributed to Bourne’s resignation, and present the story of his departure as a cautionary tale for today’s drug policy reformers.

    Peter Mark Roget (1779-1869) is best known for his Thesaurus, a project completed late in his long life. He trained as a physician, practiced medicine, and was interested in many branches of science. Much of his life was dedicated to the systematization of knowledge and identifying relationships. Although not an experimentalist in the modern sense of the word, he contributed to "neuroscience" in journal and encyclopaedia articles, as well as in books and lectures. He wrote extensively on comparative physiology, sensory systems, phrenology, optics, and various disorders affecting the nervous system. He viewed his two-volume Bridgewater Treatise of 1834 as his most significant achievement, turning to physiology and comparative anatomy to argue that God's existence can be seen in how living forms and their components are designed. Roget was active in many scholarly organizations, most notably the Royal Society of London, where he served for more than two decades as its secretary before "retiring" to pursue his Thesaurus.

    The Cambro-Ordovician strata of the Midwest of the United States is a primary target for potential geological storage of CO2 in deep saline formations. The objective of this project is to develop a comprehensive evaluation of the Cambro-Ordovician strata in the Illinois and Michigan Basins above the basal Mount Simon Sandstone since the Mount Simon is the subject of other investigations including a demonstration-scale injection at the Illinois Basin Decatur Project. The primary reservoir targets investigated in this study are the middle Ordovician St Peter Sandstone and the late Cambrian to early Ordovician Knox Group carbonates. The topic of this report is a regional-scale evaluation of the geologic storage resource potential of the St Peter Sandstone in both the Illinois and Michigan Basins. Multiple deterministic-based approaches were used in conjunction with the probabilistic-based storage efficiency factors published in the DOE methodology to estimate the carbon storage resource of the formation. Extensive data sets of core analyses and wireline logs were compiled to develop the necessary inputs for volumetric calculations. Results demonstrate how the range in uncertainty of storage resource estimates varies as a function of data availability and quality, and the underlying assumptions used in the different approaches. In the simplest approach, storage resource estimates were calculated from mapping the gross thickness of the formation and applying a single estimate of the effective mean porosity of the formation. Results from this approach led to storage resource estimates ranging from 3.3 to 35.1 Gt in the Michigan Basin, and 1.0 to 11.0 Gt in the Illinois Basin at the P10 and P90 probability level, respectively. The second approach involved consideration of the diagenetic history of the formation throughout the two basins and used depth-dependent functions of porosity to derive a more realistic spatially variable model of porosity rather than applying a

    It is a mistake to think that all personal experiences with cancer are the same. For certain, all cancer patients do confront the possibility of an early death and the prospect of pain and suffering due to the tumor and its treatment. But the specific emotional issues differ with each patient and each family, and the responses to these issues take many forms. In an eloquent and moving film, "Cancer: A Personal Journey. Notes from the Edge.," we are given the privilege of accompanying a remarkable young physician, Peter J. Morgan, on his journey with cancer, a two and one-half year journey that ended with his death at age 31. At age 29, Dr. Morgan, an internist-in-training who intended to pursue a career in hematology and oncology, noted a mass on his leg. Tragically, metastasis to the lungs had already taken place at the time of diagnosis of a synovial sarcoma. There followed the all-too-familiar story of chemotherapy and experimental treatments, pain, debilitation, and ultimately demise, and in itself this experience would move us with the sorrow of a precious life lost. What makes this particular story so remarkable are the insights of this young physician and the struggle for survival of a spirit that would not succumb to the "chaos" of cancer. In the two-year period of his life as a cancer patient, Peter Morgan kept a diary that records his thoughts, his emotional turmoil, and his reflections on life and an untimely death. In particular, we are able to understand the need for his spiritual self to remain alive and to grow despite the deterioration of his physical being. And we see that spiritual triumph in his compelling relationships with his family and his colleagues, in his reflections on art and music and nature, and most of all in his writings and his appreciation of the immense possibilities for joy in life. This is not an easy journey to watch, but the intense sadness of his experience is balanced by his friendships and the great satisfaction he derived

    The area of the Gulf of Peter the Great is socially, economically and culturally one of the most important regions for the Russian Far East. At the same time, there have been reported palpable natural hazards, which pose a real threat to local infrastructure. Complex field team of the Gramaberg VNIIOkeangeologia institute carried out geological and geophysical studies of natural hazards in the water area and coastal zone of the gulf in the summer and autumn of 2012. The research program included - geodetic deformation monitoring of the coastal zone by the HDS 3000 Leica tachometer; - echo sounding of the underwater part of the coastal slope by the LCX-37C depth sounder equipped with active external 12-channel GPS Lowrance antenna LGC-3000; - high-frequency acoustic profiling by GeoPulse Subbotom Profilier with oscillator frequency of 12.2 kHz for the study of bottom sediments to a depth of 40 m; - hydromagnetic measurements by SeaSPY Marine Magnetics magnetometer for investigation of deep geological structure; - sonar measurements by GEO SM C-MAX, 325 kHz frequency emitters for studying seafloor features; - studies of the water column (sensing and sampling); - bottom sediment sampling. Analytic work was performed by mass spectrometry, atomic absorption spectrophotometry, chromatography, gas chromatography-mass spectrometry, gamma spectrometry and included the following. For water - the content of Fe, Mn, Cd, As, Pb, Cu, Co, Ni, Cr, Zn, Hg in solution and in suspension, polycyclic aromatic compounds, organochlorine pesticides, oil, methane. For sediments - grade analysis, mineralogical analysis of sand, determination of Fe, Mn, Cd, As, Pb, Cu, Co, Ni, Cr, Zn, Hg content; identification of petroleum products, polychlorinated biphenyls, organochlorine pesticides, the specific activity of Cs-137. As a result, a set of geological maps was composed: maps of pre-Quaternary and Quaternary rocks and deposits, lithological map, geomorphological map, map of engineering

    We compare, for the first time, the performance of a simplified atmospheric radiative transfer algorithm package, the Corti-Peter (CP) model, versus the more complex Fu-Liou-Gu (FLG) model, for resolving top-of-the-atmosphere radiative forcing characteristics from single-layer cirrus clouds obtained from the NASA Micro-Pulse Lidar Network database in 2010 and 2011 at Singapore and in Greenbelt, Maryland, USA, in 2012. Specifically, CP simplifies calculation of both clear-sky longwave and shortwave radiation through regression analysis applied to radiative calculations, which contributes significantly to differences between the two. The results of the intercomparison show that differences in annual net top-of-the-atmosphere (TOA) cloud radiative forcing can reach 65 %. This is particularly true when land surface temperatures are warmer than 288 K, where the CP regression analysis becomes less accurate. CP proves useful for first-order estimates of TOA cirrus cloud forcing, but may not be suitable for quantitative accuracy, including the absolute sign of cirrus cloud daytime TOA forcing that can readily oscillate around zero globally.

    In 1933 the Turkish Republic formally offered university positions to 30 German-speaking academics who were dismissed with the coming to power of the National Socialist Government. That initial number went up to 56 with the inclusion of the technical assistants. By 1948 the estimated total had increased to 199. Given renewable five-year contracts with salaries substantially higher than their Turkish counterparts, the foreign émigrés were to implement the westernization program of higher education. The ten year-old secular Turkish Republic's extensive social reforms had encompassed the adoption of the Latin alphabet, and equal rights for women, removing gender bias in hiring. Such a high concentration of émigré academics in one institution, "the highest anywhere in the world," provides a unique opportunity to study a subject which has been neglected. In this article two cases in psychology will be examined: Wilhelm Peters (1880-1963), who came, via Britain, to Istanbul in 1936 from the University of Jena in Germany, and Muzafer Sherif (1906-1988) who went to the United States from Ankara University in 1945. The purpose of the comparative analysis is to identify the features that are specific to the German experience, and those that are shared and underlie translocation in science within the multifaceted complexity of the process of forced migration.

  14. The Wnt Target Protein Peter Pan Defines a Novel p53-independent Nucleolar Stress-Response Pathway.

    Proper ribosome formation is a prerequisite for cell growth and proliferation. Failure of this process results in nucleolar stress and p53-mediated apoptosis. The Wnt target Peter Pan (PPAN) is required for 45 S rRNA maturation. So far, the role of PPAN in nucleolar stress response has remained elusive. We demonstrate that PPAN localizes to mitochondria in addition to its nucleolar localization and inhibits the mitochondrial apoptosis pathway in a p53-independent manner. Loss of PPAN induces BAX stabilization, depolarization of mitochondria, and release of cytochrome c, demonstrating its important role as an anti-apoptotic factor. Staurosporine-induced nucleolar stress and apoptosis disrupt nucleolar PPAN localization and induce its accumulation in the cytoplasm. This is accompanied by phosphorylation and subsequent cleavage of PPAN by caspases. Moreover, we show that PPAN is a novel interaction partner of the anti-apoptotic protein nucleophosmin (NPM). PPAN depletion induces NPM and upstream-binding factor (UBF) degradation, which is independent of caspases. In summary, we provide evidence for a novel nucleolar stress-response pathway involving PPAN, NPM, and BAX to guarantee cell survival in a p53-independent manner. © 2015 by The American Society for Biochemistry and Molecular Biology, Inc.

    The Xenopus oocyte possesses a large maternal store of ribosomes, thereby uncoupling early development from the de novo ribosome biosynthesis required for cell growth. Brix domain-containing proteins, such as Peter Pan (PPan), are essential for eukaryotic ribosome biogenesis. In this study, we demonstrate that PPan is expressed maternally as well as in the eye and cranial neural crest cells (NCCs) during early Xenopus laevis development. Depletion of PPan and interference with rRNA processing using antisense morpholino oligonucleotides resulted in eye and cranial cartilage malformations. Loss of PPan, but not interference with rRNA processing, led to an early downregulation of specific marker genes of the eye, including Rx1 and Pax6, and of NCCs, such as Twist, Slug and FoxD3. We found that PPan protein is localized in the nucleoli and mitochondria and that loss of PPan results in increased apoptosis. These findings indicate a novel function of PPan that is independent of its role in ribosome biogenesis.

    The Oreochromis mossambicus (Peters) population inhabiting Lake Loskop, South Africa, is characterized by a high incidence of obesity and pansteatitis. We investigated potential links between the impaired health of Lake Loskop O. mossambicus and the endocrine system by assessing the expression of selected genes associated with the thyroid and adrenal endocrine axes as well as peroxisome proliferator-activated receptor gamma (pparg). Moreover, contaminant-induced thyroid and/or metabolic modulation in Lake Loskop water was evaluated using juvenile O. mossambicus in laboratory exposures. The expression of thyroid hormone receptor alpha (thra) and type 2 deiodinase (dio2) was higher in Lake Loskop O. mossambicus than fish from another population, suggesting a degree of thyroid disruption. The altered gene expression may be a consequence, rather than cause of obesity. Expression of dio2 and pparg was higher in juvenile O. mossambicus exposed to unfiltered compared to filtered lake water, and our data suggest fasting as causative factor. Micro-organism abundance can therefore be a confounding factor in studies applying molecular markers to test for thyroid modulation by environmental waters. Pansteatitis was not a significant source of variance in the expression of any of the genes investigated, suggesting that the disease is not associated with disrupted endocrine signalling.

    One of the world's most enduring companies, Nestle epitomizes everything that today's high-flying, headline-grabbing companies are not. It respects technology but doesn't consider it central to strategy. It values growth but prefers it controlled. It seeks talented professionals but wants only those who are modest in word and deed. Nestle CEO Peter Brabeck is skeptical of the relentless push for radical transformation heard from every quarter. He believes, instead, in continuous improvement through slow and steady change. Big, dramatic change is fine for a crisis, Brabeck says, but not every company is in crisis all the time. Many companies are like Nestle--performing well, growing and innovating, without frenzy, without bloodshed. While he acknowledges that every company must change in order to compete in today's turbulent marketplace, Brabeck makes the focus of his work identifying and strengthening those aspects of Nestle that should stay the same. For example, Nestle eschews the noise and energy swirling around technology. Many companies make technology the focal point of strategy, Brabeck says, but Nestle is about people, products, and brands. The company uses technology to create better products but keeps it in its right place--the background. Brabeck also talks candidly about how to fight complacency in a successful company, how to institutionalize collaboration in a decentralized organization, and how to resist pressure from analysts and money managers and focus on long-term, sustainable and profitable growth--in short, how to win the war without the revolution.

    2001-12-01

    Peter Singer's recent appointment to Princeton University created considerable controversy, most of it focused on his proposal for active euthanasia of disabled infants. Singer articulates utilitarian ideas that often appear in public discussions of euthanasia. Drawing on Pope John Paul II's work on ethics and suffering, I argue that Singer's utilitarian theory of value is impoverished. After introducing the Pope's ethic based on the imago dei, I discuss love as self-gift. I show how this concept supports a theory of value in which spiritual goods are preeminent over material goods. I then describe how suffering reveals spiritual goods, discussing how participation in Christ's suffering can alter our perception of value. I also consider how communal responses to suffering provide opportunities for self-giving. Third, I consider Singer's proposal for killing infants with hemophilia, arguing that it arbitrarily ignores spiritual goods. I then discuss proposals to kill anencephalic infants, discussing how parental responses to their suffering can demonstrate an extraordinary love in seemingly hopeless circumstances. I conclude by calling for a more sustained social response to euthanasia initiatives.

    Mesophotic reef fish assemblages (30-90 m depth) of the small and remote St. Peter and St. Paul's Archipelago (SPSPA), Mid-Atlantic Ridge, Brazil, were characterized using remotely operated vehicles. Ordination analyses identified distinct fish assemblages in the upper (30-50 m) and lower (50-90 m) mesophotic zones, the former characterized by high abundances of species that are also abundant at euphotic reefs ( Caranx lugubris, Melichthys niger, Stegastes sanctipauli and Chromis multilineata) and the latter dominated by two mesophotic specialists ( Prognathodes obliquus and Chromis enchrysura). Planktivores dominated fish assemblages, particularly in the upper mesophotic zone, possibly due to a greater availability of zooplankton coming from the colder Equatorial Undercurrent in mesophotic depths of the SPSPA. Turf algae, fleshy macroalgae and scleractinian corals dominated benthic assemblages between 30 and 40 m depth, while bryozoans, black corals and sponges dominated between 40 and 90 m depth. Canonical correspondence analysis explained 74 % of the relationship between environmental characteristics (depth, benthic cover and complexity) and structure of fish assemblages, with depth as the most important independent variable. Juveniles of Bodianus insularis and adults of P. obliquus and C. enchrysura were clearly associated with branching black corals ( Tanacetipathes spp.), suggesting that black corals play key ecological roles in lower mesophotic reefs of the SPSPA. Results from this study add to the global database about mesophotic reef ecosystems (MREs) and provide a baseline for future evaluations of possible anthropogenic and natural disturbances on MREs of the SPSPA.

    Although coloniality is widespread among mammals, it is still not clear what factors influence composition of social groups. As animals need to adapt to multiple habitat and environmental conditions throughout their range, variation in group composition should be influenced by adaptive adjustment to different ecological factors. Relevant to anthropogenic disturbance, increased habitat modification by humans can alter species' presence, density, and population structure. Therefore, it is important to understand the consequences of changes to landscape composition, in particular how habitat modification affects social structure of group-forming organisms. Here, we combine information on roosting associations with genetic structure of Peter's tent-roosting bats, Uroderma bilobatum to address how different habitat characteristics at different scales affect structure of social groups. By dividing analyses by age and sex, we determined that genetic structure was greater for adult females than adult males or offspring. Habitat variables explained 80% of the variation in group relatedness (mainly influenced by female relatedness) with roost characteristics contributing the most explained variation. This suggests that females using roosts of specific characteristics exhibit higher relatedness and seem to be philopatric. These females mate with more males than do more labile female groups. Results describe ecological and microevolutionary processes, which affect relatedness and social structure; findings are highly relevant to species distributions in both natural and human-modified environments.

    Isolated oceanic islands constitute interesting model systems for the study of colonization processes, as several climatic and oceanographic phenomena have played an important role in the history of the marine ichthyofauna. The present study describes the presence of two morphotypes of Caranx lugubris, in the St. Peter and St. Paul Archipelago located in the mid-Atlantic. Morphotypes were compared in regard to their morphological and cytogenetic patterns, using C-banding, Ag-NORs, staining with CMA3/DAPI fluorochromes and chromosome mapping by dual-color FISH analysis with 5S rDNA and 18S rDNA probes. We found differences in chromosome patterns and marked divergence in body patterns which suggest that different populations of the Atlantic or other provinces can be found in the Archipelago of St. Peter and St. Paul.

    Peters anomaly is a rare developmental abnormality of the anterior segment of the eye and is one of the main causes of congenital corneal opacities. Typically, histopathology of Peters anomaly shows immature or absent Descemet's membrane and attenuated endothelial cells in the area of the corneal opacity, in addition to thinning or absence of Bowman's membrane and defects in the posterior stroma. In this report, we present a novel histopathological finding, which has not been previously reported, in the Descemet's membrane of a patient who is clinically diagnosed with Peters anomaly. A 7-years old female child with developmentally delayed was born of a normal pregnancy, labor, and delivery. Apparent bilateral corneal opacifications were present at birth. On ophthalmologic examination, the child had a visual acuity of FC/20 cm in the right eye and that of FC/10 cm in the left one. Horizontal nystagmus and congenital cataract were found in both eyes. Slit-lamp examination revealed bilateral central corneal opacities which covered the iris and pupils. High-frequency UBM and AS-OCT both showed a shallow anterior chamber with multiple areas of iridocorneal adhesions and no corneal lenticular touch in each eye. A corneal specialist performed a penetrating keratoplasty with extra-capsular cataract extraction and intraocular lens implantation. Histopathologic procedures were conducted on the host corneal button, including Hematoxylin-Eosin stain and Periodic Acid-Schiff stain. All the sections were examined by light microscopy. The "multiple-layer" structure of the Descemet's membrane described in our case has not been reported before as in association with abnormalities of the cornea tissues in Peters anomaly. Such pathological finding need to be reported to enhance further understanding of the special structure of Descemet's membrane as an abnormality during embryogenesis and neural crest cell differentiations.

    Complex molecular interactions dictate the developmental steps that lead to a mature and functional cornea and lens. Peters anomaly is one subtype of anterior segment dysgenesis especially due to abnormal development of the cornea and lens. MSX2 was recently implicated as a potential gene that is critical for anterior segment development. However, the role of MSX2 within the complex mechanisms of eye development remains elusive. Our present study observed the morphologic changes in conventional Msx2 knockout (KO) mice and found phenotypes consistent with Peters anomaly and microphthalmia seen in humans. The role of Msx2 in cornea and lens development was further investigated using IHC, in situ hybridization, and quantification of proliferative and apoptotic lens cells. Loss of Msx2 down-regulated FoxE3 expression and up-regulated Prox1 and crystallin expression in the lens. The FoxE3 and Prox1 malfunction and precocious Prox1 and crystallin expression contribute to a disturbed lens cell cycle in lens vesicles and eventually to cornea-lentoid adhesions and microphthalmia in Msx2 KO mice. The observed changes in the expression of FoxE3 suggest that Msx2 is an important contributor in controlling transcription of target genes critical for early eye development. These results provide the first direct genetic evidence of the involvement of MSX2 in Peters anomaly and the distinct function of MSX2 in regulating the growth and development of lens vesicles.

    The monitoring of hazardous natural processes In coastal and shelf zone of the gulf of Peter the Great (sea of Japan) in 2012-2013 was made by staff of the Gramberg Institute VNIIOKEANGEOLOGIA . The complex of field researches are: - laser scanning beaches (tachometer Leica HDS 3000); - echosounding underwater coastal slope (sounder-Navigator LCX-37C); - high-frequency acoustic profiling (GeoPulse Subbotom Profilier); - hydromagnetic shooting magnetometer SeaSPY Marine Magnetics; - sonar shooting (complex GEO-CM-MAX); - research of the water column (sounding and sampling); - bottom sampling, including gasgeochemical shooting. The result of this work is the following conclusions: 1. As the shore, and the underwater slope of the district are experiencing the preemptive destruction, the areas of which are quantitative and spatially prevail over the stable and accumulate zones (except the shores of the inland parts of bays and gulfs). 2. The rate of destruction of coast in the Gulf of Peter the Great is 1-20 meters for 100 years, that could pose a serious danger to the population and infrastructure. 3. Number of gasgeochemical anomalies on the shelf of the Gulf of Peter the Great spatially associated with fault lines, limiting blocks of the earth's crust within shelf. 4. Perhaps it is these faults are of the greatest seismic hazard in the moment. 5. Danger of themselves gas emissions The following significant hazards and risks to the region have been studied: seismic and tsunami destruction of shore, gas emissions, technogenic pollution.

    Four large-scale (2--8 Ma) T-R sedimentary sequences of M. Ord. age (late Chaz.-Sherm.) were delimited by Witzke Kolata (1980) in the Iowa area, each bounded by local to regional unconformity/disconformity surfaces. These encompass both siliciclastic and carbonate intervals, in ascending order: (1) St. Peter-Glenwood fms., (2) Platteville Fm., (3) Decorah Fm., (4) Dunleith/upper Decorah fms. Finer-scale resolution of depth-related depositional features has led to regional recognition of smaller-scale shallowing-upward cyclicity contained within each large-scale sequence. Such smaller-scale cyclicity encompasses stratigraphic intervals of 1--10 m thickness, with estimated durations of 0.5--1.5 Ma. The St. Peter Sandst. has long been regarded as a classic transgressive sheet sand. However, four discrete shallowing-upward packages characterize the St. Peter-Glenwood interval regionally (IA, MN, NB, KS), including western facies displaying coarsening-upward sandstone packages with condensed conodont-rich brown shale and phosphatic sediments in their lower part (local oolitic ironstone), commonly above pyritic hardgrounds. Regional continuity of small-scale cyclic patterns in M. Ord. strata of the Iowa area may suggest eustatic controls; this can be tested through inter-regional comparisons.

    The Hudson's Bay Company, founded in 1670, controlled the vast watershed of Hudson Bay until 1869. Its principal interest in the fur trade required maps and surveys as well as observations of native people and their habits, native species and their habitat, weather and conditions affecting travel. Accurate astronomical observations in western Canada began in 1768 when William Wales and Joseph Dymond wintered at Fort Churchill on the western shore of Hudson Bay and determined the longitude of that place in preparation for the transit of Venus the following spring. As competition forced the Company to establish inland posts, an urgent need arose for better maps and so, on the recommendation of Wales, the Company hired its first surveyor, Philip Turnor in 1778. At Buckingham House, a prairie outpost of the Company, Turnor schooled David Thompson and Peter Fidler in the art of astronomical surveying during the summer of 1790. Fidler's notebook provides a fascinating look at the rigorous training he received. Over the next twenty years, Thompson and Fidler made definitive maps covering all of western Canada. To achieve this, they made hundreds of astronomical observations using meridian altitudes for latitude and using lunar distances as well as phenomena of Jupiter's satellites for longitude. Their extensive work will be summarized and used to assess the accuracy of their methods. In addition, hundreds of observations of the aurora, mainly recorded by Fidler as part of his meteorological journal, will be shown to illustrate a maximum frequency of occurrence about 1795 and 1805, corresponding to the times of maxima in solar activity.

    Saint Peter and Saint Paul's Archipelago is a collection of 15 islets and rocks remotely located in the equatorial Atlantic Ocean. In this particular site, the present project intended to assess the biodiversity and biotechnological potential of bacteria from the actinomycete group. This study presents the first results of this assessment. From 21 sediment samples, 268 strains were isolated and codified as BRA followed by three numbers. Of those, 94 strains were grown in liquid media and submitted to chemical extractions with AcOEt (A), BuOH (B), and MeOH (M). A total of 224 extracts were screened for their cytotoxic activity and 41 were significantly active against HCT-116 cancer cells. The obtained IC50 values ranged from 0.04 to 31.55 μg/ml. The HR-LC/MS dereplication analysis of the active extracts showed the occurrence of several known anticancer compounds. Individual compounds, identified using HR-MS combined with analysis of the AntiMarin database, included saliniketals A and B, piericidins A and C and glucopiericidin A, staurosporine, N-methylstaurosporine, hydroxydimethyl-staurosporine and N-carbamoylstaurosporine, salinisporamycin A, and rifamycins S and B. BRA-199, identified as Streptomyces sp., was submitted to bioassay-guided fractionation, leading to isolation of the bioactive piericidins A and C, glucopiericidin, and three known diketopiperazines, cyclo(l-Phe-trans-4-OH-l-Pro), cyclo(l-Phe-l-Pro), and cyclo(l-Trp-l-Pro). © 2016 Wiley-VHCA AG, Zürich.

    The difficult task of achieving worldly success while also storing up spiritual treasure is perennially with us, in good times and in bad. Today, however, as the economy has cooled and companies have demonstrated their mortality, questions about meaning and value appear more relevant, even urgent. HBR associate editor David A. Light recently spoke with the Reverend Peter J. Gomes, one of the nation's best-known preachers and the minister at Harvard University's Memorial Church, about why and how it is both possible and necessary to reconcile a life of success with a life of faith. To do so, says Gomes, you must first "get used to it"--come to terms with the age-old tension between being rich in spirit and rich in worldly goods. Second, you should "get over it"--arrive at an understanding of the value and responsibilities associated with power and wealth. Finally, "get on with it"--figure out how you can live your life spiritually while continuing to lead in the business world. For those wondering how to get on with spiritual development, Gomes cites the growing phenomenon of senior executives gathering with peers--out of shared need, not shared accomplishment--to pray, study sacred texts, and share their religious life together. He counsels that it's never too late to get on with it: We can amend life at any time, whether we're 35, 45, or 75. Gomes concludes that business will continue to be one of the most significant forces in American culture, but it will always struggle against people's need for a perspective that is beyond this world's.

    Genetic and environmental agents that disrupt organogenesis are numerous and well described. Less well established, however, is the role of delay in the developmental processes that yield functionally immature tissues at birth. Evidence is mounting that organs do not continue to develop postnatally in the context of these organogenesis insults, condemning the patient to utilize under-developed tissues for adult processes. These poorly differentiated organs may appear histologically normal at birth but with age may deteriorate revealing progressive or adult-onset pathology. The genetic and molecular underpinning of the proposed paradigm reveals the need for a comprehensive systems biology approach to evaluate the role of maternal-fetal environment on organogenesis."You may delay, but time will not" Benjamin Franklin, USA Founding Father.

    Analysis of the effectiveness of guppy (Poecilia reticulata Peters) immunization based on measurements of antibody (Ab) titers suffers from a shortage of reagents that can detect guppy antibodies (Abs). To overcome this problem, we immunized mice with different preparations of guppy immunoglobulins (Igs) and used the mouse antisera to develop a quantitative enzyme-linked immunosorbent assay (ELISA). The most efficient immunogen for mouse immunization was guppy Igs adsorbed on protein A/G beads. Antisera from mice boosted with this immunoglobulin (Ig) preparation were highly specific and contained high Ab titers. They immunoreacted in a Western blot with Ig heavy and light chains from guppy serum, and Ig heavy chain from guppy whole-body homogenate. The mouse anti-guppy Ig was applied in an ELISA aimed at comparing the efficiency of different routes of guppy immunization against Tetrahymena: (i) anal intubation with sonicated Tetrahymena (40,000 Tetrahymena/fish in a total volume of 10 μL) mixed with domperidon, deoxycholic acid and free amino acids (valine, leucine, isoleucine, phenylalanine and tryptophan), or (ii) intraperitoneal (i.p.) injection of sonicated Tetrahymena in complete Freund's adjuvant (15,000 Tetrahymena/fish in total a volume of 20 μL). Negative control fish were anally intubated with the intubation mixture without Tetrahymena, or untreated. ELISA measurement of anti-Tetrahymena Ab titer revealed a significantly higher level of Abs in i.p.-immunized guppies, compared to the anally intubated and control fish. In addition, the efficiency of immunization was tested by monitoring guppy mortality following (i) i.p. challenge with Tetrahymena (900 Tetrahymena/fish) or (ii) cold stress followed by immersion in water containing 10,000 Tetrahymena/mL. Fish mortality on day 14 post-Tetrahymena infection by i.p. injection exceeded 50% in the control and anally intubated fish, compared to 31% in i.p.-immunized fish. Immunization did not protect from

    Three novel isolates (A-354(T), A-328, and A-384) were retrieved from apparently healthy scleractinian Madracis decactis in the remote St Peter & St Paul Archipelago, Mid-Atlantic Ridge, Brazil. The novel isolates formed a distinct lineage based on the phylogenetic reconstruction using the 16S rRNA and pyrH gene sequences. They fell into the Mediterranei clade and their closest phylogenetic neighbour was V. mediterranei species, sharing upto 98.1 % 16S rRNA gene sequence similarity. Genomic analysis including in silico DDH, MLSA, AAI and genomic signature distinguished A-354(T) from V. mediterranei LMG 19703 (=AK1) with values of 33.3, 94.2, 92 %, and 11.3, respectively. Phenotypically, the novel isolates can be differentiated from V. mediterranei based on the four following features. They do not grow at 8 % NaCl; use D-gluconic acid but not L-galactonic acid lactone as carbon source; and do not have the fatty acid C18:0. Differentiation from both the other Mediterranei clade species (V. maritimus and V. variabilis) is supported by fifteen features. The novel species show lysine decarboxylase and tryptophan deaminase, but not gelatinase and arginine dihydrolase activity; produce acetoin; use α-D-lactose, N-acetyl-D-galactosamine, myo-Inositol, D-gluconic acid, and β-hydroxy-D,L-butyric acid; and present the fatty acids C14:0 iso, C15:0 anteiso, C16:0 iso, C17:0 anteiso, and C17:1x8c . Whole-cell protein profiles, based on MALDI-TOF, showed that the isolates are not clonal and also distinguished them from the closes phylogenetic neighbors. The name Vibrio madracius sp. nov. is proposed to encompass these novel isolates. The G+C content of the type strain A-354(T) (=LMG 28124(T)=CBAS 482(T)) is 44.5 mol%.

    Abstract The family Phyllostomidae belongs to the most abundant and diverse group of bats in the Neotropics with more morphological traits variation at the family level than any other group within mammals. In this work, we present data of chromosome banding (G, C and Ag-NOR) and Fluorescence In Situ Hybridization (FISH) for representatives of Rhinophylla pumilio Peters, 1865 collected in four states of Brazil (Amazonas, Bahia, Mato Grosso and Pará). Two karyomorphs were found in this species: 2n=34, FN=64 in populations from western Pará and Mato Grosso states and 2n=34, FN=62 from Amazonas, Bahia, and northeastern Pará and Marajó Island (northern). Difference in the Fundamental Number is determined by variation in the size of the Nucleolar Organizer Region (NOR) accompanied with heterochromatin on chromosomes of pair 16 or, alternatively, a pericentric inversion. The C-banding technique detected constitutive heterochromatin in the centromeric regions of all chromosomes and on the distal part of the long arm of pair 15 of specimens from all localities. FISH with a DNA telomeric probe did not show any interstitial sequence, and an 18S rDNA probe and silver staining revealed the presence of NOR in the long arm of the pair 15, associated with heterochromatin, and in the short arm of the pair 16 for all specimens. The intra-specific analysis using chromosome banding did not show any significant difference between the samples. The comparative analyses using G-banding have shown that nearly all chromosomes of Rhinophylla pumilio were conserved in the chromosome complements of Glossophaga soricina Pallas, 1766, Phyllostomus hastatus Pallas, 1767, Phyllostomus discolor Wagner, 1843 and Mimon crenulatum Geoffroy, 1801, with a single chromosomal pair unique to Rhinophylla pumilio (pair 15). However, two chromosomes of Mimon crenulatum are polymorphic for two independent pericentric inversions. The karyotype with 2n=34, NF=62 is probably the ancestral one for the other

    The nature and distribution of organic carbon in marine waters depends on: 1) biological productivity and revenue of the autochthonous organic matter to the bottom; 2) sediment grain-size composition and conditions of dumping, which in turn depends of hydrothermic regime, topography, speed River mist and received major erosion products; 3) living conditions of the benthos (the quantity consumed of OM, gas regime of habitats, physiological capacity of heterotrophs). Autochthonous OM of phytoplankton plays a dominant role in the processes of formation of humus in aquatic conditions. Bottom sediments at different distance from the shoreline to depths from 0.5 up to 480 m of the Sea of Japan, which are formed in various conditions of facies, were selected as the objects of study. There is no clear relationships to the amount of organic matter in bottom sediments on the characteristics of the distribution and nature of living matter in the oceans and seas. This is because the process of sedimentation and fossilization of organic matter on the seabed and the ocean floor depends on many factors (currents, depth). Humus of studied bottom sediments in composition can be attributed mainly to the humic type. Nonhydrolyzing rest is 70-90%. This is characteristic of bottom sediments formed in facial types of small bays, internal coastal shelf bights and the underwater slope. At a fraction of the carbon of humic acids in organic matter, ranging from 4 to 80% of the amount of humic and fulvic acids. Fulvic acids content is much less. This is due to more favourable conservation situation of humic acids in precipitation with high content of organic matter, whereas fulvic acids in aquatic environments are more labile and almost not dumped. Despite the fact humic acids are not the most stable component (s), however, with increased content of humic acids, the mobility of organic matter and removing it from the bottom sediments are reduced.

    Peters et al. (2014) argued that ε180W excesses in iron meteorites originated as the decay product of 184Os. They also suggested that compositional heterogeneities, leading to variable Os/W ratios within a single iron, was the most likely explanation for discrepant ε180W values measured in different studies of the same meteorites. In Cook et al. (2014), we showed that irradiation by galactic cosmic rays (GCR) can induce large variations in ε180W. These effects provide at least a partial explanation for the observed ε180W excesses. Additionally, they can explain why ε180W values may vary both among members of a particular iron meteorite group (e.g., IVB irons), as well as between different specimens of a single iron meteorite (e.g., Weaver Mountains). We used GCR-corrected ε180W data to re-estimate the possible role of 184Os decay in generating ε180W excesses and found that any radiogenic production of 180W was much smaller than suggested by Peters et al. (2014). The preceding comment by Peters et al. (2015) on our 2014 paper contains criticisms that focus mainly on the following topics: the influence of an s-process deficit in W isotopes on ε180W in some iron meteorites, our sample selection for the construction of our isochron, and the potential effect of sample compositional heterogeneity on Os/W ratios and how this may impact our isochron slope. We address each of these in turn below.

    The study aimed at providing the psychometric properties of Polish version of Peters et al. Delusion Inventory (PPDI) (1999) and assessing the prevalence of delusion-like experiences among healthy subjects in the Polish population. Polish version of PDI was developed on the basis of back translation procedure. The scale was completed by 421 adult subjects. On the basis of the scores, the factor analysis, the reliability of the scale and the frequency of delusion-like experiences in the Polish population were calculated. The Polish version of Peters et al. Delusion Inventory has satisfactory reliability (Cronbach's alpha ranged from 0.084 to 0.87). The examination of scree plot suggests a single factor solution. The participants confirmed the incidence of, on average, 12.5 (SD=6.9), out of 40 different experiences measured using PDI. In the current study the most frequently asserted delusion-like belief is that people say things with double meaning (79.8% of participants), while the least likely beliefs were those similar to delusions observed among psychiatric patients (2.37% of participants). The Polish version of PDI is characterised by good psychometric properties and can be used for delusion-like experiences assessment in non-clinical population. The frequency of delusion-like experiences in the Polish population varies from 2 to 80% depending on their content.

    The coast of northern Primorye region, north of Peter the Great Bay has been sparsely studied in regards to its molluscan fauna, with just a few works reviewing the distribution of local mollusks. This work presents a survey of the shallow water heterobranch sea slugs currently occurring around Kievka Bay to Oprichnik Bay, Russia. Thirty-nine species of sea slugs were found in this study and the new species Cadlina olgae sp. nov., described herein. Most (24) of the species occurring in the area have widespread ranges in the northern Pacific Ocean. The eight species are endemic for the Sea of Japan and adjacent part of the Sea of Okhotsk. Seven other occur also in northern Atlantic and Arctic waters. Thirteen found species are not known from Peter the Great Bay but known from adjacent northern Pacific waters. The finding of a previously undescribed species emphasizes the need of further surveys, particularly in subtidal and deeper waters, in order to improve the knowledge on this neglected fauna in Primorye.

    The quality of abstracts presented at a conference reflects the academic activity and research productivity of the surgical/scientific association concerned. The abstract to publication rate (44.5 % internationally), is an important indicator of the quality of presented research. To evaluate the publication rate and impact of abstracts presented at the plenary session of the Sir Peter Freyer Surgical Symposium over a 25-year period (1989-2014), and identify factors influencing publication. Plenary abstracts were identified from abstract books of the Symposium from 1989-2014. The authors, institution, subspecialty and research subject were recorded. A Medline search with name of the first and last author, key words and content of all abstracts was conducted to identify related publications. The impact factor (IF) of the journal and the time to publication was recorded. 298 presented abstracts resulted in 168 publications (publication rate: 56 %). Basic Science research accounted for 80 % (n = 237) of the total number of presentations with the remaining 20 % (n = 61) being categorised as clinical research. Overall, cancer research accounted for 48 % of presented work. The average time to publication was 2 ± 7 years, while 11 % of all published studies achieved publication in the year of the symposium. The median impact factor for published research was 3.558 (IF range 0-39). These results indicate that the quality of papers presented at the Sir Peter Freyer Surgical Symposium compares favourably with international equivalents, making this meeting an important forum for Irish Academic Surgery.

    Peters plus syndrome is a rare recessive autosomal disorder comprising ocular anterior segment dysgenesis, short stature, hand abnormalities and distinctive facial features. It was related only to mutations in the B3GALTL gene in the 13q12.3 region. In this study, we undertook the first functional analysis of a novel c.597-2 A>G splicing mutation within the B3GALTL gene using an ex-vivo approach. The results showed a complete skipping of exon 8 in the B3GALTL cDNA, which altered the open reading frame of the mutant transcript and generated a PTC within exon 9. This finding potentially elicits the nonsense mRNA to degradation by NMD (nonsense-mediated mRNA decay). The theoretical consequences of splice site mutations, predicted with the bioinformatics tool Human Splice Finder, were investigated and evaluated in relation to ex-vivo results. The findings confirmed the key role played by the B3GALTL gene in typical Peters-plus syndromes and the utility of mRNA analysis to understand the primary impacts of this mutation and the phenotype of the disease.

    PETer (Protection and Emergency of the Territory) has been developed since 2006 as a tool to manage all the information available to perform a wide range of Civil Protection activities. Based on MapObjects spatial support, it was relied on capacity to manage data from different sources and at different scale, offering practical GIS-tools for a technical and practical use during crisis state. At the first stages of the development, after different assessment, critical on-field analysis and a direct proof on test area, the approach came into sight like a valid database management for the entire dataset, but quite static, not full-blown for every emergency necessity, too complicate and not enough user-friendly, considering people in charge during emergency management, the quick change of state with many parameters involved and also uncertainty, hesitation, confusion or general panic among decision makers. As a second step of research, a more down-to-earth methodology targeted to cope with the aftermath of critical events is presented here. It takes advantage of Geographical Information Systems (GIS), Decision Support Systems (DSS), and Information and Communication Technology (ICT) to prepare, apply and coordinate Civil Protection plans. The main aim was to set up and manage contingency plans in advance; that is, to identify and prepare people in charge to take action to define the activities to be performed, to be aware of available resources and to optimize the communication system among the people involved, in order to efficiently face a prospective crisis phase. A disaster preparedness plan should anticipate the demands for a disaster relief operation and indicate the most effective way of joining those requirements.

  6. [Poverty, demographic growth, and birth control: a critique of Peter Singer s ethical perspective on the relationship between rich and poor].

    PubMed

    Romero, D E

    1998-01-01

    This article analyzes the relationship between population growth and ethical principles relating to poverty. The paper is a critical approach to the thesis presented by Peter Singer in his book Practical Ethics. The first part briefly examines the principal topics of his thesis. The author then analyzes the basis of Singer's theory with respect to the following questions: 1. Is overpopulation the main reason for poverty? Is it possible to establish an association between the poverty phenomenon and population growth? 2. Is Singer s demographic perspective valid? 3. Can problems of resource distribution be ignored when talking about poverty from an ethical perspective? 4. Is it true that birth control policy was successfully implemented in Mexico, Colombia, and Brazil? 5. Does Singer s position on population growth have a negative influence on the "collective imagination"? The paper concludes by suggesting some useful arguments for understanding an ethical perspective towards poverty.

    The discussion on the development of public health affairs was invigorated anew by the report on public health in Germany of Leopoldina/Acatech/Union of the German Academies of Sciences and Humanities of the year 2015. The report urges strengthening of public health and global health in Germany and addresses explicitly the Public Health Service (PHS). This indispensable inclusion of the PHS in further strategic planning offers for the first time an opportunity for a comprehensive and sustainable practice/policy transfer on the federal, state and community level, and also a chance for a sustainable network with modern academic public health institutions together with representation of medical specialization in public health at universities, that has been absent so far. A Johann-Peter Frank model for cooperation and stepwise modelling of this transition with the inclusion of the Academies for Public Health Service is presented. © Georg Thieme Verlag KG Stuttgart · New York.

    The red hybrid tilapia, Oreochromis niloticus (Linnaeus, 1758) x O. mossambicus (Peters, 1852) is a fertile hybrid used in the semi-intensive level of fish culture in the Northeast of Brazil. It is a territorial cichlid and is highly aggressive towards conspecifics during the breeding season. The purpose of this study was to investigate and describe the aggressive behaviour displayed by the males of this hybrid in non-reproductive and reproductive contexts. Behavioural observations revealed that aggression displayed by the reproductive males of red hybrid tilapia included threatening, undulation, parallel, lateral and frontal attacks, chasing, escape and submission. Possession of a territory influenced male aggressiveness, which was more intense in their own territory than that observed in a neutral situation. The males built nests, irrespective of female presence. All the behavioural patterns were in accordance with those previously described for one parental species, the Nile tilapia, O. niloticus.

    This article presents near N-S compression, active uplift tectonism, and the consequent abyssal mantle exhumation of the Saint Peter and Saint Paul Rock, Equatorial Atlantic Ocean. The mantle peridotite ridge is about 80 km long, 25 km wide, 3800 m high, and of near E-W direction. The ridge flanks are extremely steep with sub-vertical scarps of about 2000 m of relative height. The Flandrian wave-cut and the 14C datings for the carbonaceous algae of the Saint Peter and Saint Paul Rock indicate active uplift of 1.5 mm/year. The tectonic factures shows conjugated system of N-S compression tending slightly to NW-ES. Close to the peridotite ridge, the earthquakes with near N-S compression focal mechanism take place. The southern half of the peridotite ridge is constituted by undeformed peridotite. The existence of corrugation morphology indicates that the mantle rocks are originated from old megamullion. On the other hand, the northern half is composed of strongly deformed mylonitic peridotite suggesting that the ultramafic rocks are possibly originated from sub-crustal abyssal mantle of old transform fault. The mylonite structure is intensely perturbed indicating the tectonic events which disturbed the original parallel structure. The Saint Paul transform fault zone is characterized by E-W trend right lateral movement and the near N-S compression is unlikely. Therefore, an unusual local geotectonic process is expected. This tectonism was originated from the plate boundary jump at about 8 Ma, caused by the emergence of a new ridge segment, and the new transform fault is oblique to the relative plate movement. This angular discrepancy causes the compression perpendicular to the oblique transform fault, of near N-S direction, which squeeze out the sub-crustal abyssal mantle up to sea level. Therefore, the peridotite Ridge is considered to be a pressure ridge of the strike-slip movement of the Saint Paul transform fault.

    The Cambro-Ordovician strata of the Illinois and Michigan Basins underlie most of the states of Illinois, Indiana, Kentucky, and Michigan. This interval also extends through much of the Midwest of the United States and, for some areas, may be the only available target for geological sequestration of CO{sub 2}. We evaluated the Cambro-Ordovician strata above the basal Mt. Simon Sandstone reservoir for sequestration potential. The two targets were the Cambrian carbonate intervals in the Knox and the Ordovician St. Peter Sandstone. The evaluation of these two formations was accomplished using wireline data, core data, pressure data, and seismic data from the USDOE-funded Illinois Basin Decatur Project being conducted by the Midwest Geological Sequestration Consortium in Macon County, Illinois. Interpretations were completed using log analysis software, a reservoir flow simulator, and a finite element solver that determines rock stress and strain changes resulting from the pressure increase associated with CO{sub 2} injection. Results of this research suggest that both the St. Peter Sandstone and the Potosi Dolomite (a formation of the Knox) reservoirs may be capable of storing up to 2 million tonnes of CO{sub 2} per year for a 20-year period. Reservoir simulation results for the St. Peter indicate good injectivity and a relatively small CO{sub 2} plume. While a single St. Peter well is not likely to achieve the targeted injection rate of 2 million tonnes/year, results of this study indicate that development with three or four appropriately spaced wells may be sufficient. Reservoir simulation of the Potosi suggest that much of the CO{sub 2} flows into and through relatively thin, high permeability intervals, resulting in a large plume diameter compared with the St. Peter.

    Small- and Ultra-Small Angle Neutron Scattering (SANS and USANS) provide powerful tools for quantitative analysis of porous rocks, yielding bulk statistical information over a wide range of length scales. This study utilized (U)SANS to characterize shallowly buried quartz arenites from the St. Peter Sandstone. Backscattered electron imaging was also used to extend the data to larger scales. These samples contain significant volumes of large-scale porosity, modified by quartz overgrowths, and neutron scattering results show significant sub-micron porosity. While previous scattering data from sandstones suggest scattering is dominated by surface fractal behavior over many orders of magnitude, careful analysis of our data shows both fractal and pseudo-fractal behavior. The scattering curves are composed of subtle steps, modeled as polydispersed assemblages of pores with log-normal distributions. However, in some samples an additional surface-fractal overprint is present, while in others there is no such structure, and scattering can be explained by summation of non-fractal structures. Combined with our work on other rock-types, these data suggest that microporosity is more prevalent, and may play a much more important role than previously thought in fluid/rock interactions.

    In this work, the ultrastructural features and taxonomic position of the green microalga infesting the horse mussel Modiolus modiolus from the north-western Pacific (Vityaz Bay, Peter the Great Bay, Sea of Japan) are reported. Mussels were collected monthly from May to September of 2009. In different months, the prevalence of mussels with green tissues was 16.6-62.5% (mean 43%). The most affected organs were the mantle, digestive gland and gonad. Histological analysis revealed severe infiltration of the connective tissue by hemocytes containing the alga cells. Electron microscopy showed that the alga was morphologically similar to the green algae from the genus Coccomyxa (Chlorophyta: Chlorococcales). Two new primers were designed to generate partial small subunit (SSU) rRNA sequences of the green alga from M. modiolus. Phylogenetic analysis based on the comparison of the SSU rRNA sequences of the trebouxiophyceans confirmed an affiliation of the green alga with the genus Coccomyxa. The sequence (1296 bases) of the green alga from M. modiolus was most closely related to the sequence CPCC 508 (AM981206) (identity 100%), obtained from an acid-tolerant, free-living chlorophyte microalga Coccomyxa sp. and to the sequences EU127470 (identity 99.3%) and EU127471 (identity 99.7%) of the green alga, presumably the true Coccomyxa parasitica, infecting the blue mussel Mytilus edulis from the Flensburg Fjord (North Atlantic).

    Five novel strains of Photobacterium (A-394T, A-373, A-379, A-397 and A-398) were isolated from bleached coral Madracis decactis (scleractinian) in the remote St Peter & St Archipelago (SPSPA), Mid-Atlantic Ridge, Brazil. Healthy M. decactis specimens were also surveyed, but no strains were related to them. The novel isolates formed a distinct lineage based on the 16S rRNA, recA, and rpoA gene sequences analysis. Their closest phylogenetic neighbours were Photobacterium rosenbergii, P. gaetbulicola, and P. lutimaris, sharing 96.6 to 95.8% 16S rRNA gene sequence similarity. The novel species can be differentiated from the closest neighbours by several phenotypic and chemotaxonomic markers. It grows at pH 11, produces tryptophane deaminase, presents the fatty acid C18:0, but lacks C16:0 iso. The whole cell protein profile, based in MALDI-TOF MS, distinguished the strains of the novel species among each other and from the closest neighbors. In addition, we are releasing the whole genome sequence of the type strain. The name Photobacterium sanctipauli sp. nov. is proposed for this taxon. The G + C content of the type strain A-394T (= LMG27910T = CAIM1892T) is 48.2 mol%. PMID:25024905

    Peters' anomaly (PA) is a congenital defect of the anterior chamber of the eye. We identified a family in which an apparently balanced chromosomal translocation t(1;7) (q41;p21) was associated with PA. Based on this observation, detailed molecular characterizations of the breakpoint regions and candidate genes were carried out. A candidate gene from each breakpoint was identified: on chromosome 7, histone deacetylase 9 (HDAC9), disrupted by the translocation breakpoint, and on chromosome 1, transforming growth factor-beta2 (TGFbeta2) located 500 kb proximal to the breakpoint. An additional lysophospholipase-like 1 gene (LYPLAL1), localized approximately 200 kb distal to the chromosome 1 breakpoint, was also identified and characterized. Although only the HDAC9 gene is disrupted by the breakpoint, we consider that TGFbeta2 represents the main candidate gene in this family, which is elicited in mice by the Tgfbeta2-null status and by the TGFbeta2-induced cataractus changes in animal models. As an alternative scenario, which is supported by the ability of class II HDACs to mediate extracellular TGF-beta stimuli to core histone deacetylation in promoter-adjacent regions, we propose the hypothesis of digenic inheritance. Inappropriate or inadequate TGFbeta2 expression, together with deficient mediation of these signals at the transcription level, due to an altered HDAC9 isoforms ratio, may also lead to the observed ocular phenotype.

    Both the temporal and spatial variability of storm surge water level (WL) curves are usually not taken into account in flood risk assessments as observational data are often scarce. In addition, sea-level rise (SLR) can further affect the variability of WLs. We analyze the temporal and spatial variability of the WL curve of 75 historical storm surge events that have been numerically simulated for St. Peter-Ording at the German North Sea coast, considering the effects induced by three SLR scenarios (RCP 4.5, RCP 8.5, and a RCP 8.5 high end scenario). We assess potential impacts of these scenarios on two parameters related to flooding: overflow volumes and fullness. Our results indicate that due to both the temporal and spatial variability of those events the resulting overflow volume can be two or even three times greater. We observe a steepening of the WL curve with an increase of the tidal range under the three SLR scenarios, although SLR induced effects are relatively higher for the RCP 4.5. The steepening of the WL curve with SLR produces a reduction of the fullness, but the changes in overflow volumes also depend on the magnitude of the storm surge event.

    The aim of this study was to investigate the planktonic and the holobiont Madracis decactis (Scleractinia) microbial diversity along a turbulence-driven upwelling event, in the world's most isolated tropical island, St Peter and St Paul Archipelago (SPSPA, Brazil). Twenty one metagenomes were obtained for seawater (N = 12), healthy and bleached holobionts (N = 9) before, during and after the episode of high seawater turbulence and upwelling. Microbial assemblages differed between low turbulence-low nutrient (LLR) and high-turbulence-high nutrient (HHR) regimes in seawater. During LLR there was a balance between autotrophy and heterotrophy in the bacterioplankton and the ratio cyanobacteria:heterotrophs ~1 (C:H). Prochlorales, unclassified Alphaproteobacteria and Euryarchaeota were the dominant bacteria and archaea, respectively. Basic metabolisms and cyanobacterial phages characterized the LLR. During HHR C:H < < 0.05 and Gammaproteobacteria approximated 50% of the most abundant organisms in seawater. Alteromonadales, Oceanospirillales, and Thaumarchaeota were the dominant bacteria and archaea. Prevailing metabolisms were related to membrane transport, virulence, disease, and defense. Phages targeting heterotrophs and virulence factor genes characterized HHR. Shifts were also observed in coral microbiomes, according to both annotation–indepent and -dependent methods. HHR bleached corals metagenomes were the most dissimilar and could be distinguished by their di- and tetranucleotides frequencies, Iron Acquision metabolism and virulence genes, such as V. cholerae-related virulence factors. The healthy coral holobiont was shown to be less sensitive to transient seawater-related perturbations than the diseased animals. A conceptual model for the turbulence-induced shifts is put forward.

    PubMed

    Shah, Esha

    2017-01-01

    The main focus of this essay is to closely engage with the role of scientist-subjectivity in the making of objectivity in Lorraine Daston and Peter Galison's book Objectivity, and Daston's later and earlier works On Scientific Observation and The Moral Economy of Science. I have posited four challenges to the neo-Kantian and Foucauldian constructions of the co-implication of psychology and epistemology presented in these texts. Firstly, following Jacques Lacan's work, I have argued that the subject of science constituted by the mode of modern science suffers from paranoia. It is not the fear of subjectivity interfering with objectivity but the impossibility of knowing the truth of the real that causes paranoia. Here, I have argued that it is not the ethos of objectivity that drives epistemology as Daston and Galison suggest, but the pathos of paranoia. The second challenge builds upon Kant's own denial that the perfect correspondence between the human will and the moral law is possible. Kant himself thought that an ethical human act is impossible without the component of "pathology." This questions Daston and Galison's argument that there is always ethical imperative at the core of epistemic virtue. The third challenge contests the way Daston and Galison take appearance for being in their application of the Foucauldian concept of technologies of the self in modeling the master scientist-self. The fourth challenge questions the notion of the psychological and unconscious in the making of epistemology in Daston's later and earlier work. Against this background, I aim to make a claim that understanding and disclosing "entities" in the scientific domain presupposes an understanding of "being" in general. My goal is to open up the discussion for an alternative conception of the scientist-subject and thereby an affective and existential formulation of science.

    Norman McOmish Dott (1897-1973) developed surgical neurology in Edinburgh, Scotland, and was a scholar of worldwide renown. One of Dott's most notable contributions to neurosurgery was his understanding of hypothalamic physiology, mostly acquired through the comprehensive study of patients with lesions involving this region of the diencephalon, particularly craniopharyngiomas (CPs). Recognition of symptoms caused by hypothalamic disturbances allowed him to predict the accurate anatomical relationships between CPs and the hypothalamus, despite the rudimentary radiological methods available during the 1930s. His sophisticated knowledge permitted Dott to perform radical removals of CPs originating within the third ventricle floor with acceptable success. Between 1934 and 1937, he operated on 4 CP cases originating in the hypothalamus, achieving a satisfactory postoperative outcome in 3 of the 4 patients. Aware of the strong attachment of hypothalamic CPs to the infundibulo-tuberal area, Dott used a double transbasal and transventricular approach to these lesions, a strategy providing an optimal view and control of the tumor boundaries. The decisive mentorship of several legendary figures of physiology and neurosurgery greatly influenced Dott's surgical evolution. The experimental pituitary gland work he performed with Sir Edward Sharpey-Schäfer at the beginning of his career stirred Dott's curiosity about the issue of hypothalamus-pituitary relationships. As a result, he decided to move to Peter Bent Brigham Hospital (Boston, Massachusetts) in 1923, to train in neurosurgery and neuropathology under the guidance of the leaders in these fields, Harvey Williams Cushing (1869-1939) and Percival Sylvester Bailey (1892-1973). They inspired the young Dott and shared with him their clinical and pathological expertise, in addition to their surgical strategies for best approaching and removing these challenging tumors. In time, Dott would come to surpass his mentors. This

    As part of this twentieth anniversary special issue I was asked to write a few words about Richard Palmer, the one permanent fixture on the journal over its twenty year history. Richard and I go back a (very) long way! He began his career at IOP Publishing in Bristol in 1971 while my publishing career with the American Physical Society began a little earlier, located at Brookhaven National Laboratory on Long Island NY. Since then, and for nearly forty years we have met often, if irregularly, at many locations throughout the world. As members of two very strong physics organizations we were clearly in competition with each other to seek out and publish the best physics research. At the same time we frequently exchanged experiences and policy ideas for dealing with serious violations of scientific ethical standards and how academic society-run journals can best serve the general scientific community. Overall my relationship with Richard has been a most rewarding one and I shall miss his opinions and sage advice. Richard: Compatriot; competitor; collaborator; I salute you!

    The paper begins by situating Singer within the British meta-ethical tradition. It sets out the main steps in his argument for utilitarianism as the 'default setting' of ethical thought. It argues that Singer's argument depends on a hierarchy of reasons, such that the ethical viewpoint is understood to be an adaptation--an extension--of a fundamental self-interest. It concludes that the argument fails because it is impossible to get from this starting-point in self-interest to his conception of the ethical point of view. The fundamental problem is its mixing the immiscible: the Humean subordination of reason to interest with the Kantian conception of reason as universal and authoritative.

    In the framework of the National School "Science and Cultural Heritage: from Non-Invasive Analysis to 3D Recostruction" (19-23 September 2016, Messina-Valle d'Agrò, Italy), organized by the Department of Mathematical and Computer Sciences, Physical Sciences and Earth Sciences of the University of Messina, in co-opeartion with the Department of Geosciences of the University of Malta and in agreement with the Regional Order of Geologists of Sicily, non-invasive investigations have been performed aimed at the exploitation, fruition and safeguard of the archaeological site of Scifì and the St Peter and Paul Church in Agro Valley. Different georadar prospections [1-2] were carried out at both sites. Prospections have been performed by using a Ris-Hi mode system equipped with a dual antenna at the central frequencies of 200 and 600 MHz [3], and made along an orthogonal grid with 40 cm spacing. Data processing involved a zero timing, background removal on all tracks, a gain in-depth, a one-dimensional Butterworth filtering and a Kirchoff migration. Measurements of ambient vibrations were also performed [4-5], that revealed the absence of remarkable side heterogeneities, or large impedance contrasts associated surface stratigraphy. Measurements were also taken to measure the natural frequency of the church. In the two investigated sites, we also conducted spectroscopic investigations. The analysis was mainly focused on the study of variations, in terms of elemental composition by means of X-ray fluorescence (XRF) measurements as well as Raman spectrospopy which allow to determine the elemental composition of the sample under investigation. In addition, several images (by means of drones) were also collected in order to create a detailed 3D model for each site the ultimate goal of creating a digital archive for the virtual use of sites of interest.

    The present article presents characteristics of the therapeutic and health promoting potential of the Expedition Bay, (part of the Peter the Great Bay, the Sea of Japan), known to be a deposit of therapeutic sea muds. The great variety of local therapeutic natural resources, viz. sea muds, sea weeds, friendly climate, beeches, etc., can be used for the treatment and prevention of various diseases. The Expedition Bay was designated as a local area of recreational and therapeutic value that can be used as a basis for the creation and further development of the multi-field health resort centre (or medical spa) that would attract patients from other regions of Russia and the surrounding countries. The future centre would provide medical services based in the first place on the classical methods of climatic and peloid therapy, thalassotherapy (heliotherapy, aeroionotherapy, bathing, marine algae therapy, etc.) as well as the modern balneotherapeutic and spa technologies, therapeutic tourism for the purpose of rehabilitation and health promotion.

    Chlorophyll- a concentration ( C chl) variations in the cross section within and outside the Peter the Great Bay shelf during different stages of the winter-spring phytoplankton bloom in 2003-2005 has been considered based on a ship (obtained during the R/V Akademik M.A. Lavrent'ev voyage of February 26 to March 9, 2003) and MODIS-Aqua spectroradiometer and the SeaWiFS color-scanner satellite data. A comparison of the C chl variability obtained from the ship and satellite data indicates that these data are inconsistent. According to satellite data obtained at the MUMM atmospheric correction, the C chl variability is distorted less than the NIR-correction data. Studying the variations in the coefficients of light absorption by the detritus and yellow substance ( a dg) and light backscattering by suspended particles ( b bp), C chl, chlorophyll- a fluorescence ( F chl) according to the satellite data allow us to state that the variations in the discrepancy between the satellite and ship C chl values are mainly caused by the variations in the content of the detritus and yellow substance in water. Based on the satellite data, it has been revealed that the a dg values increase with increasing wind mixing after the phytoplankton bloom (about 2-5 km areas where the a dg, C chl, F chl, and bbp values abruptly increased in 2005, apparently due to eddy formation). It has been indicated that the F chl characteristic, which is close to C chl, increases when the favorable conditions for the phytoplankton bloom deteriorate. Therefore, this characteristic cannot be used to identify C chl under the indicated conditions.

    The Natural Science Club was founded in Fiume/Rijeka (Naturwissentschaflichen Club in Fiume/Club di scienze naturali in Fiume) on November 28th 1883. The foundation charter stipulated no restriction on language use, and lectures could be held in any language. Right from the start, the Club had active women members, and one of them, Rosa Fatour, the headmistress of the municipal school, held a lecture entitled "Development of anthropology" as early as in 1889. The Club started to publish a bilingual bulletin in German and Italian in 1896 (Mittheilungen des Naturwissenshaftlichen Clubs in Fiume/Bolletino del Club di scienze naturali in Fiume), bringing not only reports on lectures held in the Club, but also important scientific and professional papers. In 1896, several sections were founded within the Club, as follows: 1. The Committee for Röntgen, whose aim was to purchase the Röntgen apparatus. This task was completed in 1897. The apparatus was ceded to the municipal hospital in 1899, and the Committee was disbanded. 2. The Photography Section, lead initially by A. Riegler. The section organized several photo exhibitions in which women often took part.3. The Prehistoric Research Section was founded subsequent to the discovery of the remains of an old fortification in the town. This section collaborated closely with the municipal museum. Since founding and until 1902, Prof Peter Salcher held important positions in the Club; he founded the Röntgen Committee and the Photography Section; he himself gave 31 lectures and was editor of the German part of the Bulletin.

  17. Peter Debye: Nazi collaborator or secret opponent?

    Reiding, Jurrie

    2010-11-01

    In January 2006, the so-called "Debye Affair" emerged, triggered by the publication of a Dutch book on Einstein. Debye was accused of Nazi collaboration in his capacity as chairman of the German Physical Society when he requested, in December 1938, the remaining Jewish members to leave the society. Within a month, two Dutch universities deleted Debye's name from their research institute and scientific award, and this led, both nationally and internationally, to a heated discussion. The Dutch government commissioned The Netherlands Institute for War Documentation to investigate the case. In its final report, the accusation was toned down to 'opportunism'. This paper is based on new information. Above all, I have researched Debye's extensive American archive. This archive disclosed the correspondence (1940-1963) with his friend Paul Rosbaud, an important MI6 intelligencer in Berlin during the Nazi period. The correspondence, combined with information from other sources, suggests that Debye might have been one of Rosbaud's informants. Therefore, this paper also includes a powerful warning against hasty and definitive conclusions.

    In this paper on Equus, an attempt is made to explore from an analytic point of view the psychodynamics of the protagonist, Alan, and his therapist, Dysart. Both the preoedipal and oedipal aspects are discussed. The main thesis of my remarks are aimed at revealing how the author seized upon a real event, namely the blinding of horses by an English lad, and has woven this into his own fantasies. It is emphasized that the playwright in addition employed various sophisticated ego functions that enabled him to express these fantasies in Greek mythological terms (the oedipal myth and the voyage of Agamemnon). The final work then comprises a true creative effort, since, as I mention in my introductory remarks on the creative process, it employs both primary and secondary process thinking and symbolism. The final synthesis represents an eloquent mythopoetic expression and combination of id and ego (autonomous ego functions).

    In the last years of his life, Rubens (1577-1640) lived happily with his wife and children on his Het Steen estate. During this period he worked and reworked a painting that had special meaning to him—Landscape by Moonlight (1635-40), now at the Courtauld Gallery in London. After a highly successful career painting religious and secular portraits, allegories, and occasional landscapes, Rubens put an extraordinary amount of effort into this final landscape. He was well known as a person who would commit to memory ideas and themes that he would use in future works. This paper reviews Rubens' attention to the visualization of nature, his personal connections to Elsheimer, Galileo, and Peiresc, and explores his possible depiction of constellations recalled from memory and placed within the cloudy skies in his Landscape by Moonlight.

    The purpose of this study was to evaluate the local control, pattern of recurrence, overall survival, and prognostic factors of patients with squamous cell carcinoma (SCC), adenocarcinoma, and undifferentiated carcinoma of the paranasal sinuses (PNS) and nasal cavity (NC) presenting to our center for curative treatment over a 10-year period. Between 1991 and 2000, 60 patients with SCC (n = 32), adenocarcinoma (n = 25), and undifferentiated carcinoma (n = 3) of the PNS or NC were identified. Forty patients received surgery and postoperative radiotherapy, four surgery alone; 11, radiotherapy alone; three radical radiotherapy after surgical recurrence; one, chemoradiotherapy and surgery; and one, induction chemotherapy followed by radiotherapy. Forty-seven patients (78%) were seen with T3-4 disease; however, most (92%) were node negative on initial assessment. The predominant failure pattern was local disease persistence or recurrence. The estimated 2- and 5-year local control rates were 63% and 49%, respectively. Orbital and neural invasion significantly affected local control. The estimated 2- and 5 year overall survival rates were 57% and 40%, respectively. Local failure remains the dominant cause for poor outcome in this group of patients. Because of the proximity of critical normal structures, the ability to perform adequate surgery and to deliver effective radiotherapy is limited in many cases. The use of postoperative concurrent chemoradiotherapy warrants further investigation. Copyright 2004 Wiley Periodicals, Inc.

  15. Regional evaluation of hydrologic factors and effects of pumping, St Peter-Jordan aquifer, Iowa

    USGS Publications Warehouse

    Burkart, M.R.; Buchmiller, Robert

    1990-01-01

    Pumping has caused changes in the flow system that include regional declines in the potentiometric surface of the aquifer. Simulation indicates that pumping through 1980 increased net vertical leakage into the aquifer to about double the predevelopment rate. Discharge across lateral boundaries has been substantially reduced or reversed by pumping. Aquifer storage provided about one-third of the water required to supply pumping in the 1970's. Simulation of future conditions, assuming no increase in pumping rates, indicates that the rate of decline in water levels will decrease by the year 2020. As equilibrium with pumping is approached in 2020, 75 percent of the pumpage will be balanced by vertical leakage, eight percent by water released from aquifer storage, and 17 percent by increases in boundary recharge or decreases in boundary discharge. Future pumping at an increasing rate of about 10 percent per decade of the average pumping rate in 1975 will require about one and one-half times the vertical leakage of the 1971-1980 period and about fivetimes the net inflow from lateral boundaries; however, the rate of water released from aquifer storage will be about half the 1970's rate. Under these conditions, the head in the aquifer will continue to decline at an almost constant rate until 2020.

  16. Nitrate source indicators in ground water of the Scimitar Subdivision, Peters Creek area, Anchorage, Alaska

    USGS Publications Warehouse

    Wang, Bronwen; Strelakos, Pat M.; Jokela, Brett

    2000-01-01

    A combination of aqueous chemistry, isotopic measurement, and in situ tracers were used to study the possible nitrate sources, the factors contributing to the spatial distribution of nitrate, and possible septic system influence in the ground water in the Scimitar Subdivision, Municipality of Anchorage, Alaska. Two water types were distinguished on the basis of the major ion chemistry: (1) a calcium sodium carbonate water, which was associated with isotopically heavier boron and with chlorofluorocarbons (CFC's) that were in the range expected from equilibration with the atmosphere (group A water) and (2) a calcium magnesium carbonate water, which was associated with elevated nitrate, chloride, and magnesium concentrations, generally isotopically lighter boron, and CFC's concentrations that were generally in excess of that expected from equilibration with the atmosphere (group B water). Water from wells in group B had nitrate concentrations that were greater than 3 milligrams per liter, whereas those in group A had nitrate concentrations of 0.2 milligram per liter or less. Nitrate does not appear to be undergoing extensive transformation in the ground-water system and behaves as a conservative ion. The major ion chemistry trends and the presence of CFC's in excess of an atmospheric source for group B wells are consistent with waste-water influences. The spatial distribution of the nitrate among wells is likely due to the magnitude of this influence on any given well. Using an expanded data set composed of 16 wells sampled only for nitrate concentration, a significant difference in the static water level relative to bedrock was found. Well water samples with less than 1 milligram per liter nitrate had static water levels within the bedrock, whereas those samples with greater than 1 milligram per liter nitrate had static water levels near or above the top of the bedrock. This observation would be consistent with a conceptual model of a low-nitrate fractured bedrock aquifer that receives slow recharge from an overlying nitrate-enriched surficial aquifer.

  4. Analysis of the Papal Benediction Sign: The ulnar neuropathy of St. Peter.

    PubMed

    2015-09-01

    The origin of the Papal Benediction Sign has been a source of controversy for many generations of medical students. The question has been whether the Papal Benediction Sign posture is the result of an injury to the median nerve or to the ulnar nerve. The increasingly popular use of online "chat rooms" and the vast quantities of information available on the internet has led to an increasing level of confusion. Looking in major anatomy texts, anatomy and board review books as well as numerous internet sites the answer remains unresolved. Through the analysis of functional anatomy of the hand, cultural and religious practices of the early centuries of the Common Era and church art a clear answer emerges. It will become apparent that this hand posture results from an ulnar neuropathy.

    According to Lucian Leape, patient safety in hospitals is improving, and it is now possible to get to a level of zero defects. Growing recognition of the need for team training, use of trigger tools, improving the competency of physicians, and full disclosure and compensation to injured patients exemplify positive developments. Yet formidable barriers remain, including separatism in how doctors, nurses, and pharmacists learn; inadequate instruction in communication and team-building skills; poorly developed quality and safety curricula; lack of leadership among CEOs and hospital boards; physician apathy; absence of effective systems for accountability; and failure to believe in the possibility of eliminating medical errors and injuries.

    2006-01-01

    The structure of microbial communities of brown algae, red algae, and of the red alga Gracilaria verrucosa, healthy and affected with rotten thallus, were comparatively investigated; 61 strains of heterotrophic bacteria were isolated and characterized. Most of them were identified to the genus level, some Vibrio spp., to the species level according to their phenotypic properties and the fatty acid composition of cellular lipids. The composition of the microflora of two species of brown algae was different. In Chordaria flagelliformis, Pseudomonas spp. prevailed, and in Desmarestia viridis, Bacillus spp. The composition of the microflora of two red algae, G. verrucosa and Camphylaephora hyphaeoides, differed mainly in the ratio of prevailing groups of bacteria. The most abundant were bacteria of the CFB cluster and pseudoalteromonads. In addition, the following bacteria were found on the surface of the algae: Sulfitobacter spp., Halomonas spp., Acinetobacter sp., Planococcus sp., Arthrobacter sp., and Agromyces sp. From tissues of the affected G. verrucosa, only vibrios were isolated, both agarolytic and nonagarolytic. The existence of specific bacterial communities characteristic of different species of algae is suggested and the relation of Vibrio sp. to the pathological process in the tissues of G. verrucosa is supposed.

    Antibacterial and antiparasitic agents and a cysteine protease inhibitor (E-64) were tested against Tetrahymena infection, a serious problem in guppy production worldwide. Chemicals were tested in vitro by a colorimetric assay for Tetrahymena survival. The most effective were niclosamide, albendazole and chloroquine, with 23%, 35% and 60% survival, respectively, following 2-h exposure to 100 ppm. Longer incubation periods resulted in greater reductions in survival. Niclosamide was further studied in vivo at different dosages, administered orally to Tetrahymena-infected guppies. Mortality rates were significantly lower in all treatment groups; in trial I, 30% and 33% mortality in 5 and 40 mg kg(-1) niclosamide-fed fish vs. 59% mortality in controls; in trial II, 35%, 13% and 10% in 50, 100 and 200 mg kg(-1) niclosamide-fed fish vs. 64% in controls. The effect of the cysteine protease inhibitor E64 was tested in tissue culture, by measuring histolytic activity of the parasite (Tet-NI) on a guppy-fin cell line, based on cell depletion. Tet-NI feeding activity was significantly reduced following pretreatment with E-64 relative to non-treated Tet-NI. E-64-pretreated Tet-NI was injected i.p. into guppies: recorded mortality rates were significantly lower (35%) than that in non-treated Tet-NI (60%), suggesting inhibition of the parasite's cysteine protease as a possible therapeutic approach.

    PubMed

    Jacob, Christian

    2013-01-01

    Alcohol dependence is caused by complex interactions of multiple susceptibility genes with little effect each and environmental factors. Candidate genes influence metabolism of alcohol, such as alcohol dehydrogenase and aldehyde dehydrogenase, and modulatory transmitter systems, such as the dopaminergic, serotonergic, acetylcholinergic, gamma-aminobutyric acidergic, and various neuropeptidergic systems. Dysfunctional behavioral choices, learning, and memory are involved in the etiology of alcohol dependence. Systematic promotion and maintenance of motivation is a lifetime challenge in the treatment of alcohol use disorders. The second step of treatment management is the discontinuation of alcohol consumption. Withdrawal symptoms can be treated with gamma-aminobutyric acidergic substances such as benzodiazepines. Long-term relapse prevention is another challenge. Multimodal treatment can include naltrexone, a non-selective opioid receptor antagonist, or acamprosate, an N-methyl-D-aspartate receptor modulator, which are first line for pharmacological treatment on the basis of recent Cochrane analyses. Due to the complexity of etiology with both psychological and neurobiological factors, future treatment management of alcoholism may include the combination of individualized disorder-specific psychotherapy and drugs acting on different neuronal pathways, on the basis of individual vulnerability. However, the question remains unsolved whether an individualized approach is feasible and how subgroups should be defined.

    2000-01-01

    The complexity of care of some patients in an allergy-immunology practice may be increased by behavioral abnormalities of the patients. Facilitating adherence through the use of social support may be the most effective treatment strategy for some of the most difficult of these patients. We report three patients whose medical management problems were alleviated largely because of the participation of their support system. All three patients were stabilized because of the acceptance of responsibility and support of the physician by the designated member of the patient's support system. The range of social support used to manage nonadherent patients ranged from directly providing instructions to a family member to the consistent presence of a spouse or companion at multiple clinical visits. In all cases, the success in management was attributed largely to the presence of a support system.

    Norethindrone(NE) was evaluated for its efficacy on alteration of sex ratio of P. reticulata. Either the young fry or the brooders and the resultant fry were fed a commercial diet incorporated with NE at 0, 25, 50, 75 and 100 mg kg(-1) diet (ppm) for 30-40 d in rectangular glass aquaria; this was followed by 40-60 d rearing on NE-free diet in out-door concrete tanks. In general, the androgen treatment altered sex ratio, leading to the production of a dose dependent increase in the percentage of males. The oral administration of the steroid at 75 ppm for 40 d or 100 ppmfor 30 or 40 d to first feeding fry, yielded 100% males. On the other hand, NE administration to brooders before parturition and the resultant fry also produced an all-male population of guppy. The sex ratio of the untreated control was almost 1:1. The survival of fish in all the trials was high, ranging between 67 and 100%. Mating masculinized males ("XX" male) with normal female resulted in an all-female progeny, while crossing normal male (XY) from treatment groups with normal female sired normal sex ratio (1:1), elucidating XX-XY sex determination system in the guppy.

    Preparing to lecture on Aristotle's contribution to Nursing at the International Philosophy of Nursing Conference August 22, 2016, in Quebec City, Quebec, Canada, I came upon the recently published article by my IPONS colleague, Allmark (2016), "Aristotle for Nursing." Allmark (2016) provides a comprehensive and understandable overview of Aristotle's philosophical system including the substantial nature of being and the four causes of change. Nurses using Aristotle to support practice and theoretical research will benefit from a careful reading of Allmark to enrich their use of the realist understanding of knowledge of nature (epistemology) and the matter-form causal relationships within natural being (ontology and teleology). Allmark carefully displays the distinction between good health and flourishing; a distinction sometimes hard to grasp. Nurses are concerned with the end of health, but cannot achieve for others, the fullness of living which is flourishing. We will limit ourselves to expanding three areas that seem important, first, that nursing is much more than a productive science or craft, second, that Aristotle does provide an important note on the persistence of the soul, and, third, while Aristotle does not address the possibility of a personal creative highest being as Allmark says, his references to the divine are worth considering. © 2017 John Wiley & Sons Ltd.

    In patients with suspected osteoarthritis, start with a thorough history aimed at finding the mechanical component of the condition. Ask about past and current activities that may be loading or stressing a painful joint. Conditions to consider in the differential diagnosis are those affecting soft tissues-muscles, tendons, ligaments, and bursae. Injecting the tender are with lidocaine will help identify a separate or coexisting soft tissue disorder. Before considering drug therapy, attempt to correct any mechanical factors that may be contributing to the problem. Modify the patient's exercise routine, if necessary, and begin patients on a walking aid if a weight-bearing joint is affected.

  5. Two new cytotypes reinforce that Micronycteris hirsuta Peters, 1869 does not represent a monotypic taxon

    PubMed Central

    2013-01-01

    Background The genus Micronycteris is a diverse group of phyllostomid bats currently comprising 11 species, with diploid number (2n) ranging from 26 to 40 chromosomes. The karyotypic relationships within Micronycteris and between Micronycteris and other phyllostomids remain poorly understood. The karyotype of Micronycteris hirsuta is of particular interest: three different diploid numbers were reported for this species in South and Central Americas with 2n = 26, 28 and 30 chromosomes. Although current evidence suggests some geographic differentiation among populations of M. hirsuta based on chromosomal, morphological, and nuclear and mitochondrial DNA markers, the recognition of new species or subspecies has been avoided due to the need for additional data, mainly chromosomal data. Results We describe two new cytotypes for Micronycteris hirsuta (MHI) (2n = 26 and 25, NF = 32), whose differences in diploid number are interpreted as the products of Robertsonian rearrangements. C-banding revealed a small amount of constitutive heterochromatin at the centromere and the NOR was located in the interstitial portion of the short arm of a second pair, confirmed by FISH. Telomeric probes hybridized to the centromeric regions and weakly to telomeric regions of most chromosomes. The G-banding analysis and chromosome painting with whole chromosome probes from Carollia brevicauda (CBR) and Phyllostomus hastatus (PHA) enabled the establishment of genome-wide homologies between MHI, CBR and PHA. Conclusions The karyotypes of Brazilian specimens of Micronycteris hirsuta described here are new to Micronycteris and reinforce that M. hirsuta does not represent a monotypic taxon. Our results corroborate the hypothesis of karyotypic megaevolution within Micronycteris, and strong evidence for this is that the entire chromosome complement of M. hirsuta was shown to be derivative with respect to species compared in this study.

  8. Effect of cadmium on blood of tilapia, Oreochromis mossambicus (Peters), during prolonged exposure

    Cadmium is recognized as one of the most hazardous environmental pollutants and is toxic to many living organisms. Experimental and environmental exposure to cadmium has been reported to cause disease in humans and other mammals. Recent reviews on cadmium have reported on acute and subacute effects on fish, mechanisms of toxicity, the role of toxicity modifying factors and various sublethal effects, i.e., hematological and biochemical disorders. However, very little information is available on the subacute effects of cadmium on fish blood exposed in hard water. The present investigation, therefore, was carried out to observe the effects of cadmium on the blood of tilapia (Oreochromis mossambicus) in hard and alkaline water to determine whether cadmium causes changes in blood of fish kept in hard water in the same way it causes changes in blood of fish kept in soft water.

  12. Caught in speciation? A new host for Conchodytes meleagrinae Peters, 1852 (Decapoda, Caridea, Palaemonidae).

    2013-01-01

    During fieldwork in 2009 at Ternate, Indonesia, a pair of a pontoniine shrimp species belonging to the genus Conchodytes was collected from a bivalve mollusk of the genus Spondylus. This constitutes the first record of a species of the genus Conchodytes associated with a spondylid host. The specimens can be distinguished from other known Conchodytes species based on both morphology and colour pattern. Its COI barcode however, strongly resembles those obtained from three specimens of C. meleagrinae and is nested in the C. meleagrinae clade of the reconstructed phylogeny. Based on morphology and colouration only the specimens associated with the Spondylus bivalve would have been described as a species new to science. The modest conflicting molecular data have lead the authors to fully describe and figure the Spondylus associated specimens and compare them with the Pinctada associated specimens. Based on the present information it is decided not to give the Spondylus associated specimens the status as a distinct species but regard them as host-related (colour)morph of Conchodytes meleagrinae.

  14. Efficacy of garlic based treatments against monogenean parasites infecting the guppy (Poecilia reticulata (Peters)).

    2014-06-16

    Monogenean infections of commercially farmed fishes are responsible for significant economic losses. Garlic (Allium sativum) is a well-known spice which also possesses anti-microbial and anti-parasitical properties. The current work aimed to test the efficacy of garlic-based treatments against infection with monogenean sp. in the guppy (Poecilia reticulata). Clipped sections of tail fins of guppies heavily infected with Gyrodactylus turnbulli were exposed to aqueous garlic extract (7.5 to 30 mL L(-1)) and visually observed under a dissecting microscope. Results revealed that exposure to garlic caused detachment of parasite and cessation of movement indicating death. A positive correlation was seen between garlic concentration and time to detachment and death of parasites, which, at the highest concentration of 30 mL L(-1), occurred at 4.1 and 8.6 min, respectively. Bathing in aqueous garlic extract (7.5 and 12.5 mL L(-1)) was tested in guppies infected with G. turnbulli. Prior acute toxicity tests revealed the maximum tolerance levels of guppies to garlic extract to be 12.5 mL L(-1) for 1h. Bathing of infected fish in garlic extract (7.5 and 12.5 mL L(-1)) significantly (p<0.05) reduced infection prevalence and intensity as compared to the control. Oral treatments using dry garlic powder-supplemented diet were tested on guppies infected with G. turnbulli and Dactylogyrus sp. Fish were fed with food containing 10% and 20% dry garlic powder for 14 days. Groups fed with garlic supplemented diets showed significantly reduced (p<0.05) mean prevalence and mean intensity of parasites as compared to the control. Dietary application of garlic did not appear to affect palatability. Fresh crushed garlic was added at a level of 1 gL(-1) and applied as an indefinite bath for 14 days. This treatment was seen to significantly reduce (p<0.05) parasite prevalence and mean intensity as compared to the control. Histopathology revealed elevated muscular dystrophy in the 20% garlic-fed group, as compared to control. These findings demonstrate the potential of garlic as a natural alternative to currently used chemical treatments for monogenean sp. infection in the guppy. Copyright © 2014 Elsevier B.V.

    2012-01-01

    Background The generally poor prognosis and poor quality of life for lung cancer patients have highlighted the need for a conceptual model of integrative practice. Although the philosophy of integrative oncology is well described, conceptual models that could guide the implementation and scientific evaluation of integrative practice are lacking. Purpose The present paper describes a conceptual model of integrative practice in which the philosophical underpinnings derive mainly from integrative oncology, with important contributions from Traditional Chinese Medicine (tcm) and the discipline of nursing. The conceptual model is described in terms of its purpose, values, concepts, dynamic components, scientific evidence, clinical approach, and theoretical underpinnings. The model argues that these components delineate the initial scope and orientation of integrative practice. They serve as the needed context for evaluating and interpreting the effectiveness of clinical interventions in enhancing patient outcomes in lung cancer at various phases of the illness. Furthermore, the development of relevant and effective integrative clinical interventions requires new research methods based on whole-systems research. An initial focus would be the identification of interrelationship patterns among variables that influence clinical interventions and their targeted patient outcomes. PMID:22670104

    Computational methods and perspectives can transform the history of science by enabling the pursuit of novel types of questions, dramatically expanding the scale of analysis (geographically and temporally), and offering novel forms of publication that greatly enhance access and transparency. This essay presents a brief summary of a computational research system for the history of science, discussing its implications for research, education, and publication practices and its connections to the open-access movement and similar transformations in the natural and social sciences that emphasize big data. It also argues that computational approaches help to reconnect the history of science to individual scientific disciplines.

    2011-08-01

    Purpose: To retrospectively evaluate the treatment outcome of patients with Merkel cell carcinoma after local and/or regional treatment. Methods and Materials: Patients presenting to our center between January 1980 and July 2006 with Merkel cell carcinoma and without distant metastases were reviewed. The primary endpoint was locoregional control. Secondary endpoints were distant recurrence, survival and treatment toxicity. Results: A total of 176 patients were identified. The median age was 79 years. The median follow-up was 2.2 years for all patients and 3.9 years for those alive at the last follow-up visit. The most common primary site was the head and neck (56%), and 62 patients(35%) had regional disease at presentation. The initial surgery to the primary tumor involved (wide) local excision in 140 patients and biopsy only in 28 patients (8 patients had no identifiable primary tumor); 33 patients underwent nodal surgery. Of the 176 patients, 165 (94%) underwent radiotherapy (RT) and 29 of them also underwent concurrent chemotherapy. The median radiation dose was 50 Gy (range, 18-60). Locoregional recurrence developed in 33 patients(19%), with a median interval to recurrence of 8 months. Distant metastases developed in 43 patients(24%). Age, primary tumor size, and RT (no RT vs. <45 Gy vs. {>=}45 Gy) were predictive of locoregional control on univariate analysis. However, only RT remained significant on multivariate analysis. The estimated 5-year actuarial rate for locoregional control, progression-free survival, and overall survival was 76%, 60%, and 45%, respectively. Conclusion: The locoregional control rate for Merkel cell carcinoma in our study was comparable to those from other series using combined modality treatment with RT an integral part of treatment.

    The potential mutagenic and genotoxic effects of the herbicide atrazine were investigated in different developmental stages of Dendropsophus minutus tadpoles. These animals were exposed to 4 nominal concentrations of atrazine (2.25, 4.5, 9, and 18 mg/L) and 40 mg/L of Cyclophosphamide as a positive control, for 96 h. Negative controls were also added to the experiment. The tadpoles were divided into three groups according to Gosner's developmental stages, namely GS 25-33 as premetamorphic, GS 36-39 as prometamorphic, and GS 42-43 as metamorphic climax. Our results showed that the premetamorphic and metamorphic stages were more sensitive than the prometamorphic stage to the herbicide. A comet assay and micronucleus test for the sensitive stages demonstrated DNA damage in a concentration-dependent curve. Although a dose-response effect was not observed for the prometamorphic stage, a statistically significant difference was found between the treatment of 18 mg/L and the negative control. Moreover, the highest concentration of atrazine showed both the largest amount of DNA damage and the highest micronucleus frequency regardless of the developmental stage of D. minutus. In conclusion, atrazine was genotoxic and mutagenic for D. minutus in a dose-sensitive manner, dependent on larval developmental stages. Considering the prometamorphic stages showed no dose-response effect to atrazine, we suggest caution when using this stage in biomonitoring studies in order to avoid false negative results. Amphibians have been proven to be useful bioindicators, and we suggest replicating biomonitoring studies using different species to represent ecosystems' environmental impacts.

  5. The fatal wound of Hector, according to a drawing by Peter Paul Rubens designed for tapestry weaving.

    2001-02-01

    According to the Iliad(Chapter XXII, Verses 322-329), Hector, while fighting his last duel, was almost entirely protected by bronze armor, with only a small area "where the clavicle marks the boundary between neck and thorax" exposed. It was precisely into this area, "the shorter way to death," that Achilles thrust his lance. This fatal wound, although covering Hector with blood, allowed the victim to pronounce a few words. In designing the Story of Achilles, his fourth and last series of drawings especially designed for tapestry weaving, Rubens depicted Achilles stabbing Hector near the midline of his neck. There is evidence that Rubens was always well acquainted with the literary sources of his pictures. It is also likely that he became familiar with contemporary editions of the Iliad that were enhanced with commentaries. Realizing that the wound depicted in his original drawing should have prevented Hector from speaking, Rubens altered the scene, then showing the lance piercing the cervical vascular bundle. The careful scrutiny for literary accuracy that was typical of Rubens' artistic behavior did not prevent an additional minor imprecision in the final tapestry. Nevertheless, his outstanding expressive power enabled him to give form to a gigantic baroque representation of the death of Hector in masterly fashion.

    During World War II in 1941, the psychologist P. R. Hofstätter added an article to the debate on the crisis of psychology in a distinctly Nazi academic journal. After introducing Hofstätter and the journal, the core elements of his diagnosis and therapy recommendation beneath the National-Socialist-verbiage will be expounded. Hofstätter, a student of Karl Bühler's, ties on to his teacher's crisis well-known publication, but perceives the crisis in a broader perspective and connects it to the decline of theology and of pastoral guidance. Hofstätter's central, new aspect is the practice of psychology without which he sees it doomed. A central feature of psychological practice should be secular, non-therapeutic guidance of individuals. Various contextual facets are illuminated, Hofstätter's thwarted attempts to get a university position, the recent establishment of psychology in Germany as a discipline teaching professionals, the abolition of German military psychology, the battle for the Berlin university chair of Wolfgang Köhler.

The zones of contribution delineated by use of numerical modeling have similar orientation (parallel to regional flow directions) but significantly different areas than the zones of contribution delineated by use of hydrogeologic mapping. Differences in computed areas of recharge are attributed to the capability of the numerical model to more accurately represent (1) the three-dimensional flow system, (2) hydrologic boundaries like streams, (3) variable recharge, and (4) the influence of nearby pumped wells, compared to the analytical models.

    Acute toxicity of an azo dye-methyl red (5-40 ppm) was examined under starving conditions, on two groups of Poecilia reticulata--a freshwater fish, fed on different diets prior to their exposure to dye. Besides natural feed, fish of group-1 also received Spirulina feed for one month (feed population), whereas those of group-2 received only natural feed (non-feed population). The mortality data revealed non-feed population to be more tolerant to feed stress during acute toxicity study, whereas feed population exhibited better tolerance to the combined stress of both feed and methyl red; especially at higher concentrations of the latter. RBCs in methyl red treatments acquired different shapes (poikilocytosis) and an increase in their size (anisocytosis) was also noticed. Percentage of such abnormal RBCs was almost equal in both feed and non-feed populations, except at a lower concentration (5 ppm), at which percentage of poikilocytic RBCs was lesser in the feed population. RBC counts in the control non-feed fish (34.5 x 10(4)/mm3) were significantly lower than control feed population (50.0 x 10(4) /mm3). Their number decreased with an increase in methyl red concentrations in non-feed population (9-26%), but percent reduction in RBC counts was almost similar (20-26%) at various concentrations of methyl red (5-30 ppm) in the feed population. Despite reduction in RBC counts, feed population did not suffer from anemia in methyl red treatments, as evident by their RBC counts which were almost equal to control fish of non-feed population. The results suggest that Spirulina feed improves tolerance of test organism towards methyl red manifested by noticeable reduction in the cytotoxic effects on RBCs and a lower mortality rate at higher concentrations of dye.

Their biologic behaviors, 50 H. lepturus specimens which were fed and kept alive in capped bottles were studies while their way of shedding and number of newly-born young were also investigated under laboratory conditions in the process. The research revealed that in 107 H. lepturus specimens, 27 specimens (23%) were male and 80 ones (77%) were female. The results gained from 50 scorpions kept in the laboratory showed that only 10 cases (20%) had shed. Duration of emergence varies in each young from 10-20 min and delivery lasts approximately for 4-6 h. The average number of the young born was 24.3 in each delivery. It was concluded that the time of delivery and shedding in H lepturus is definitely fixed during the year and the number ofpectine denticles and length of the tail can be used to differentiate male and female H. lepturus.

  18. Robbing Peter to Pay Paul: Modeling the Dynamic Evolution of the Coastal Carbon Sink Across Multiple Landforms

    2016-12-01

    Evaluating the strength and long-term stability of the coastal carbon sink requires a consideration of the spatial evolution of coastal landscapes in both the horizontal and vertical dimensions. We present a model of the transformation and burial of carbon along a bay-marsh-upland forest complex to explore the response of the coastal carbon sink to sea level rise (SLR) and anthropogenic activity. We establish a carbon mass-balance by coupling dynamic biogeochemically-based models of soil carbon burial in aquatic, intertidal, and upland environments with a physically-based model of marsh edge erosion, vertical growth and migration into adjacent uplands. The modeled increase in marsh vertical growth and carbon burial at moderate rates of sea level rise (3-10 mm/yr) is consistent with a synthesis of 219 field measurements of marsh carbon accumulation that show a significant (p<0.0001) positive correlation with local SLR rates. The model suggests that at moderate SLR rates in low topographic relief landscapes, net marsh expansion into upland forest concomitant with increased carbon burial rates are sufficient to mitigate the associated loss of forest carbon stocks. Coastlines with high relief or barriers to wetland migration can become sources of carbon through the erosion of buried carbon stocks, but we show that the recapture of eroded carbon through vertical growth can be an important mechanism for reducing carbon loss. Overall, we show that the coastal carbon balance must be evaluated in a landscape context to account for changes in the size and magnitude of both the stocks and sinks of marsh carbon and for the transfers of carbon between coastal habitats. These results may help inform current efforts to appraise coastal carbon sinks that are beset by issues of landscape heterogeneity and the provenance of buried carbon.

    Monogenean infections of commercially farmed fishes are responsible for significant economic losses and existing chemical therapeutants, often stressful to the fish, pose associated risks. As part of a recent trend to move towards the use of alternative, plant-based remedies for commonly occurring aquaculture-related diseases, the efficiency of ginger (Zingiber officinale) was investigated against the monogenean parasite Gyrodactylus turnbulli in the guppy. In vitro trials revealed the clear anti-parasitic effects of ginger. Ethanolic and aqueous extracts, prepared from freeze dried ginger, were tested. An increase in extract concentration was associated with reduced time to parasite immobilisation, with ethanolic extract being more efficient; at 75 and 200ppt aqueous ginger extract parasites died at 65.6±2.8 and 1.8±0.2min, respectively, whereas at 5 and 40ppt ethanolic extract parasites died at 26.1±0.7 and 4.9±0.3min, respectively. Bathing G. turnbulli-infected fish in ethanolic ginger extract (i.e. 5 and 7.5ppt for 90 and 30min, respectively) significantly reduced infection prevalence and intensity when compared to the water and ethanol controls. The higher concentration (i.e. 7.5ppt) proved as equally effective as Praziquantel, the conventionally used chemical treatment for gyrodactylosis, with the fish appearing to be completely cleared of the infection in both cases. Oral treatments of G. turnbulli-infected guppies with diets supplemented with 10 and 20% ginger powder proved to be ineffective in decreasing parasite load. These findings demonstrate that immersion in ginger extract offers an effective, alternative treatment against monogenean infection in fish. Copyright © 2015 Elsevier B.V. All rights reserved.

In Axel Honneth's most prominent version of that concept, respect is closely tied to the sphere of law, and it is limited to the recognition of a Kantian-type moral autonomy of the individual. So interpreted, the…

    Pesticides used in pest control programs seem to produce many physiological and biochemical changes in fresh water organisms by influencing the activities of several enzymes. Alterations in the chemical composition of the natural aquatic environment usually effect behavioral and physiological systems of the inhabitants, particularly of the fish. Although some data are available on the effects of different pesticides on the biochemical aspects of fish gill, data on heptachlor toxicity on T. mossambica kidney are lacking. Therefore, an attempt has been made to observe certain biochemical paramets of fish, T. mossambica under heptachlor intoxication. Investigation of this nature is useful in understanding the orientation of biochemical changes during sublethal toxicity to ascertain the degree of intensity of the toxicity of heptachlor on the kidney.

    Freshwater bodies at several parts of the globe are presently undergoing progressive acidification due to acid precipitation and acid mine drainage. Significant changes under altered pH stress includes reduced primary production of algal biomass, benthic communities and rapid decline in fish populations. Studies dealing with the physiological responses of fish to acidic and alkaline water pollution are very limited. Hence, the studies dealing with the biological impact of acidity and alkalinity on the physiology and biochemistry of freshwater fish has been undertaken.

    One of the major challenges for faculty teaching general chemistry is how to encourage students to practice solving problems. We know that for students to develop chemical intuition and problem-solving skills, they must "get their hands dirty" as they decipher and unravel problems inherent to our discipline. One tool that I've used since its release in 1996 is the ChemSkill Builder, an electronic homework package. The latest version, ChemSkill Builder (CSB) 2000, version 6.1, is an excellent, effective integration of teaching and testing most quantitative and conceptual learning objectives in an interactive way. It is inexpensive and easy to use for both students and faculty. The CSB 2000 package of personalized problem sets, specifically designed to complement most general chemistry courses, is a program on CD-ROM for PC Windows users (3.1, 95, or 98), with more than 1500 questions and a 3 1/2-in. record-management disk. There is a separate grade-management disk for the instructor. It has 24 gradable chapters, each with 5 or 6 sections, plus two new chapters that are not graded: Polymer Chemistry and an Appendix of Chemical Skills. Each section begins with a short review of the topic and many have interactive explanations. If students miss an answer, they are given a second chance for 70% credit. If they still miss, the worked-out solution is presented in detail. Students can work each section as many times as they wish to improve their scores. Periodically, the students download their data directly into a PC set up by the instructor. The data can be easily converted into an ASCII file and merged with a spreadsheet. The use of CD-ROM solves the sporadic problems associated with previous versions on 3 1/2-in. disks: software glitches, failed disks, and system incompatibilities. The quality and number of graphics and interactive exercises are much improved in this latest version. I particularly enjoyed the interactive explanations of significant figures and dimensional analysis in Sections 2.3 and 2.5, the pH meter simulation in Section 18.3, the Geiger counter simulation in Section 23.5, and the new periodic table game in Appendix A. I informally polled my Fall 1999 students on their midsemester impressions of the ChemSkill Builder, version 5.1--the previous version. The preliminary results in Table 1 show an overall acceptable rating of 3.45. Note that 51% of the students thought that incorporating the CSB into the syllabus was good to very good, compared to only 16% who gave negative responses. Positive comments included "a great tool to study for the test" and "it shows how to work out the problems". The major negative comment was that the CSB was too time-consuming because the acceptable answer had to include the right number of significant figures and the correct unit--sexactly what an instructor wants the student to learn. Interestingly, the scores given appeared to be independent of the students' midterm grades, suggesting that acceptance of this product might be linked to a specific learning style. When I compared my students' responses to their Keirsey temperaments in Table 2, the ChemSkill Builder appealed somewhat more to the students who like activity, entertainment and immediate feedback (SP) or who enjoy technology and constant success experiences (NT) than to the students who prefer more group interactions (NF) or who need more structure (SJ). At the semester's end, the students were asked again to rate the ChemSkill Builder, and 97% of 155 responses either agreed (28%) or strongly agreed (69%) that it proved helpful in learning course material. Moreover, 99% thought that I should continue to incorporate the ChemSkill Builder in future courses. To summarize, the ChemSkill Builder 2000, version 6.1, will be an excellent tool for augmenting the learning process in the general chemistry classroom.

    Our paper "Upscaling geochemical reaction rates usingpore-scale network modeling" presents a novel application of pore-scalenetwork modeling to upscale mineral dissolution and precipitationreaction rates from the pore scale to the continuum scale, anddemonstrates the methodology by analyzing the scaling behavior ofanorthite and kaolinite reaction kinetics under conditions related to CO2sequestration. We conclude that under highly acidic conditions relevantto CO2 sequestration, the traditional continuum-based methodology may notcapture the spatial variation in concentrations from pore to pore, andscaling tools may be important in correctly modeling reactive transportprocesses in such systems. This work addresses the important butdifficult question of scaling mineral dissolution and precipitationreaction kinetics, which is often ignored in fields such as geochemistry,water resources, and contaminant hydrology. Although scaling of physicalprocesses has been studied for almost three decades, very few studieshave examined the scaling issues related to chemical processes, despitetheir importance in governing the transport and fate of contaminants insubsurface systems.

    Pirimiphos-methyl is a broad spectrum organophosphate insecticide and potential toxic pollutant in aquatic ecosystems. The acute toxicity of Pirimiphos-methyl (Actellic) was investigated using Guppy (Poecilia reticulata) in a 96 h static renewal laboratory bioassay. Based on probit analysis the LC50 was 0.026, 0.024, 0.022 and 0.019 ml L(-1) at 24, 48, 72 and 96 h, respectively. Analysis of Variance (ANOVA) showed that there was significant difference (p < 0.05) in the quantal response (mortality) of P. reticulata to different concentrations of Actellic at 24, 48, 72 and 96 h of exposure. Actellic insecticide is toxic to fish; therefore its indiscriminate use in aquatic environment should be discouraged.

    Hidden for the untrained eye through a thin layer of sand, laminated microbial sediments occur in supratidal beaches along the North Sea coast. The inhabiting microbial communities organize themselves in response to vertical gradients of light, oxygen or sulfur compounds. We performed a fine-scale investigation on the vertical zonation of the microbial communities using a lipid biomarker approach, and assessed the biogeochemical processes using a combination of microsensor measurements and a 13C-labeling experiment. Lipid biomarker fingerprinting showed the overarching importance of cyanobacteria and diatoms in these systems, and heterocyst glycolipids revealed the presence of diazotrophic cyanobacteria even in 9 to 20 mm depth. High abundance of ornithine lipids (OL) throughout the system may derive from sulfate reducing bacteria, while a characteristic OL profile between 5 and 8 mm may indicate presence of purple non-sulfur bacteria. The fate of 13C-labeled bicarbonate was followed by experimentally investigating the uptake into microbial lipids, revealing an overarching importance of cyanobacteria for carbon fixation. However, in deeper layers, uptake into purple sulfur bacteria was evident, and a close microbial coupling could be shown by uptake of label into lipids of sulfate reducing bacteria in the deepest layer. Microsensor measurements in sediment cores collected at a later time point revealed the same general pattern as the biomarker analysis and the labeling experiments. Oxygen and pH-microsensor profiles showed active photosynthesis in the top layer. The sulfide that diffuses from deeper down and decreases just below the layer of active oxygenic photosynthesis indicates the presence of sulfur bacteria, like anoxygenic phototrophs that use sulfide instead of water for photosynthesis.

    Cyprinodontiformes fishes (guppies) are widely distributed in Neotropical regions and use deteriorated microhabitats in rivers where few species can occur. This study was carried out in a stretch of the Paraíba do Sul River in bracketing a large urban-industrial complex. The aim was to assess eventual effects that the industrial complex could have on distribution of two closely related fish species of guppies, Phalloceros caudimaculatus and Poecilia reticulata. The area was divided into three zones: Z1, 40 km upriver of the major urban-industrial complex of Volta Redonda; Z2, just down river of the complex; and Z3, 30 km down river of the complex. Six sites (two in each zone) were sampled monthly between November 1998 and October 1999, using a standardized fishing effort with cast net throws, trays lifts and seine hauls, covering different microhabitats, that is, riffles, pools and the proximity of the river's margins. Poecilia reticulata was widely distributed, peaking at Z2, the most polluted area, while P. caudimaculatus showed the highest abundance at Z3, being almost absent in Z1. Both species occurred in high numbers throughout the year but they were scarce between April and June. Females outnumbered males for both species in most size classes and at all sites. Juveniles were more abundant than adults, with non-pregnant females outnumbering pregnant ones. Condition factor was always higher in males than females but only males P. reticulata showed significant difference among the three zones, with the highest values at Z2. The higher number of females confirms the expectation that these species can use very polluted areas and that availability of food provided by organic loads allowed their distribution all over the area. Although these two species have shown indication of spatial separation in the study area, their similar seasonal patterns of occurrence suggest that they respond in a similar way to changes in environmental conditions.
