    Ralph Steinman, an editor at the Journal of Experimental Medicine since 1978, shared the 2011 Nobel Prize in Physiology or Medicine for his discovery of dendritic cells (DCs) and their role in immunity. Ralph never knew. He died of pancreatic cancer on September 30, 3 days before the Nobel announcement. Unaware of his death at the time of their announcement, the Nobel Committee made the unprecedented decision that his award would stand. Ralph was the consummate physician-scientist to the end. After his diagnosis, he actively participated in his 4.5 years of treatments, creating experimental therapies using his own DCs in conjunction with the therapies devised by his physicians, all the while traveling, lecturing, and most of all pursuing new investigations in his laboratory. For 38 years—from his discovery of DCs to his Nobel Prize—Ralph pioneered the criteria and methods used to identify, isolate, grow, and study DCs. He and his colleagues demonstrated that DCs are initiators of immunity and regulators of tolerance. In his most recent studies, Ralph was harnessing the specialized features of DCs to design improved vaccines. The following synopsis describes some of his seminal discoveries. PMID:22216460

  3. Obituary: Ralph Asher Alpher, 1921-2007

    2007-12-01

    Ralph Asher Alpher, noted cosmologist, physicist, and educator, died on August 12, 2007, in Austin, Texas. Alpher developed the first model for primordial nucleosynthesis in the hot early Universe and, with Robert Herman, first predicted the cosmic microwave background radiation. During his long and productive career, he published over one-hundred papers, a book translation, chapters in a number of books (primarily in cosmology), and The Genesis of the Big Bang, a book about his life in cosmology, co-authored with Robert Herman. Ralph's work has been cited by the American Physical Society News as one of the Top Ten Astronomical Triumphs of the Millennium. Born in Washington, D.C., on February 3, 1921, Ralph was the youngest of four children of building contractor Samuel and Rose Maleson Alpher, immigrants from Russia and Latvia. He attended Roosevelt High School in Washington, graduating at the age of sixteen. A scholarship was offered by the Massachusetts Institute of Technology, but then suddenly withdrawn after a meeting with an alumnus. (Ralph would wonder all his life whether the withdrawal was due to his Jewish background.) Instead, he attended evening classes at George Washington University while working full time, earning his B.S. in 1943, his M.S. in 1945, and his Ph.D. in 1948. Ralph's master's thesis on the sources of energy in stars was completed with mentor George Gamow. Gamow then accepted him to work on a Ph.D. dissertation on the formation of galaxies, studying the growth of condensations in a relativistic homogeneous and isotropic expanding medium. Ralph found that such condensations would not grow, but before he finished writing, E. M. Lifshitz independently published similar results in 1946. Ralph started anew, this time modeling the buildup of elements by neutron capture in the hot, early phase of the Universe. Despite the approximations necessary in the pre-computer age, he found consistency with observed abundances of hydrogen and helium. The

    Nelson syndrome is an important complication of treatment with total bilateral adrenalectomy (TBA) for patients with refractory Cushing's disease. Although early cases of Nelson syndrome often presented with the clinical features of large sellar masses, the modern face of Nelson syndrome has changed primarily due to earlier detection (with highly resolved magnetic resonance imaging (MRI) and sensitive ACTH assays) and greater awareness of the condition, resulting in reduced morbidity and mortality. Although lack of administration of neoadjuvant pituitary radiotherapy post-TBA surgery may predict future development of Nelson syndrome, other predictive factors remain controversial. Therefore, Nelson syndrome should be screened for closely and long-term in all patients with a history of Cushing's disease and TBA. The diagnosis of Nelson syndrome remains controversial, and the pathogenesis of this condition is incompletely understood. Current hypotheses include the "released negative feedback" mechansism (residual pituitary corticotropinoma cells are "released" from the negative feedback effects of cortisol following TBA), and the "aggressive corticotropinoma" mechanism (Nelson syndrome is most likely to develop in those patients with refractory treatments - including TBA - for an underlying aggressive corticotropinoma). Effective management of Nelson syndrome with pituitary surgery and radiotherapy is often a challenge. Other therapies (such as Gamma Knife surgery and temozolomide) play an important role and merit further research into their efficacy and placement in the management pathway of Nelson syndrome. © 2014 Elsevier B.V.

    To review the pathophysiology and therapeutic modalities availble for Nelson syndrome. We reviewed the current literature including managment for Nelson syndrome. For patients with NS, surgical intervention is often the first-line therapy. With refractory NS or tumors with extrasellar involvement, radiosurgery offers an important alternative or adjuvant option. Pharmacologic interventions have demonstrated limited usefulness, although recent evidence supports the feasibility of a novel somatostatin analog for patients with NS. Modern neuroimaging, improved surgical techniques, and the advent of stereotactic radiotherapy have transformed the management of NS. An up-to-date understanding of the pathophysiology underlying Nelson Syndrome and evidence-based management is imperative. Early detection may allow for more successful therapy in patients with Nelson Syndrome. Improved radiotherapeutic interventions and rapidly evolving pharmacologic therapies offer an opportunity to create targeted, multifocal treatment regiments for patients with Nelson Syndrome.

  8. Product spaces and Nelson's inequality

    Faris, W.G.

    1976-01-01

    Certain inequalities for unbounded linear operators in L 2 extend to product spaces. This product space property is used to give a new proof that Gross's inequality for matrices implies Nelson's inequality for ordinary differential operators, and that this in turn implies Nelson's inequality for partial differential operators in infinitely many dimensions. A new proof of Gross's inequality is given. There is also a discussion of the physical meaning of Nelson's inequality in quantum field theory. The article may serve as an introduction for non-specialists to some of the recent mathematical work in this subject. (Auth.)

    2007-01-01

    The appearance of an adrenocorticotropic hormone (ACTH)-producing tumor after bilateral adrenalectomy for Cushing disease was first described by Nelson in 1958. The syndrome that now bears his name was characterized by hyperpigmentation, a sellar mass, and increased plasma ACTH levels. The treatment of Cushing disease has changed drastically since the 1950s, when the choice was adrenalectomy. Thus, the occurrence, diagnosis, and treatment of Nelson syndrome have changed as well. In the modern era of high-resolution neuroimaging, transsphenoidal microneurosurgery, and stereotactic radiosurgery, Nelson syndrome has become a rare entity. The authors describe the history of the diagnosis and treatment of Nelson syndrome. In light of the changes described, the authors believe this disease must be reevaluated in the contemporary era and a modern paradigm adopted.

  12. Nelson`s syndrome associated with a somatic frame shift mutation in the glucocorticoid recepter gene

    Energy Technology Data Exchange (ETDEWEB)

    Nelson`s syndrome is the appearance and/or progression of ACTH-secreting pituitary macroadenomas in patients who had previously undergone bilateral adrenalectomy for Cushing`s disease. Extremely high plasma ACTH levels and aggressive neoplastic growth might be explained by the lack of appropriate glucocorticoid negative feedback due to defective glucocorticoid signal transduction. To study the glucocorticoid receptor (GR) gene in Nelson`s syndrome, DNA was extracted from pituitary adenomas and leukocytes of four patients with this condition and amplified by PCR for direct sequence analysis. In one of the tumors, a heterozygous mutation, consisting of an insertion of a thymine between complementary DNA nucleotides 1188 and 1189, was found in exon 2. This frame-shift mutation led to premature termination at amino acid residue 366 of the world-type coding sequence, excluding the expression of a functioning receptor protein from the defective allele. The mutation was not detected in the sequence of the GR gene in the patient`s leukocyte DNA, indicating a somatic origin. By lowering the receptor number in tumorous cells, this defect might have caused local resistance to negative glucocorticoid feedback similar to that caused by the presence of a null allele in a kindred with the generalized glucocorticoid resistance syndrome. P53 protein accumulation, previously reported in 60% of corticotropinomas, could not be detected in any of the four pituitary tumors examined by immunohistochemistry. We suggest that a somatic GR defect might have played a pathophysiological role in the tumorigenesis of the corticotropinoma bearing this mutation. 35 refs., 3 figs., 1 tab.

    In the context of medication use, pharmaceutical literacy skills are crucial for appropriate and safe use of medication. Recognition of patients with inadequate pharmaceutical literacy in daily pharmacy practice is difficult. No instrument is yet available to support pharmacists herein. The aim of this study was therefore to develop an interview guide for pharmacists to Recognize and Address Limited PHarmaceutical literacy (RALPH). The RALPH interview guide was constructed in three phases: (1) development including a literature search, expert group discussion, and feasibility test with 15 patients; (2) pilot-test with 421 patients throughout 30 community pharmacies, and (3) final test with 508 patients to optimize the interview guide. The development phase resulted in a first interview guide comprising 15 questions: seven in the functional domain (understanding instructions), four in the communicative domain (finding and understanding medication information) and four in the critical domain (critically analyzing medication information). This version was pilot-tested in 30 pharmacies, with 147 patients during medication reviews and another 274 patients were interviewed while waiting to collect their medication. This test phase led to removal of questions that proved difficult to interpret and to rephrasing some questions. The second version including 11 questions was tested by 109 pharmacists trainees with 508 patients, resulting in the final RALPH interview guide comprising 10 questions, all directly linked to the patient's own medication: three in the functional, three in the communicative and four in the critical domain. Besides instructions on how to use the interview guide, recommendations are provided for pharmacists on how to support patients with limited pharmaceutical literacy skills. The practice-based RALPH interview guide supports pharmacists in recognizing patients with limited pharmaceutical literacy. With this insight, pharmacists can tailor their

  16. A new look at Bell's inequalities and Nelson's theorem

    International Nuclear Information System (INIS)

    Schulz, B.

    2009-01-01

    In 1985, Edward Nelson, who formulated the theory of stochastic mechanics, made an interesting remark about Bell's theorem. Nelson analysed the latter in the light of classical fields that behave randomly. He found that if a stochastic hidden variable theory fulfils certain conditions, the inequality of Bell can be violated. Moreover, Nelson was able to prove that this may happen without any instantaneous communication between the two spatially separated measurement stations. Since Nelson's article got almost overlooked by physicists, we try to review his comments on the theorem. We argue that a modification of stochastic mechanics published recently by Fritsche and Haugk can be extended to a theory which fulfils the requirements of Nelson's analysis. The article proceeds to derive the quantum mechanical formalism of spinning particles and the Pauli equation from this version of stochastic mechanics. Then, we investigate Bohm's version of the EPR experiment. Additionally, other setups, like entanglement swapping or time and position correlations, are shortly explained from the viewpoint of our local hidden-variable model. Finally, we mention that this theory could perhaps be relativistically extended and useful for the formulation of quantum mechanics in curved space-times.

    The purpose of the study was to evaluate the utility of MRI and CT in the diagnosis of Nelson's syndrome, i. e. pituitary tumours in patients bilaterally adrenalectomized for Cushing's disease. Thirteen patients, followed up for 5-29 years after adrenalectomy, were studied. In 6 of them CT and MRI revealed no changes in the pituitary gland. In the remaining 7 patients only three CT scans were suggestive of a pituitary adenoma. MRI studies with administration of gadodiamide confirmed the CT diagnosis of Nelson's tumour in 3 patients and disclosed microadenomas in a further 4 patients. Neurosurgical treatment in 4 patients confirmed the MRI findings. Additionally CT and MRI examinations were performed in 5 patients suspected of a recurrent Nelson's tumour 3-11 years after neurosurgery. MRI visualized recurrent adenomas in 3 patients that were not well seen by CT scans. In our experience MRI was more effective than CT in the diagnosis of Nelson's syndrome. (orig.).

    This paper reports that continuing a trend starting in 1983, the Nelson-Farrar refinery construction index rose slowly from 1211.6 in January 1990, to 1265.8 in December 1991. The labor component of the index rose at a more rapid rate than did the material component. The labor index rose from 1469.5 to 1558.1 over the 2-year period, while the material index rose only 2.3 points, from 824.9 to 827.2. The miscellaneous equipment index rose 52.1 points in the 2-year comparison. The category includes pumps and compressors, electrical equipment, heat exchangers, instruments, and engines. They are thus manufactured items, and their costs are a measure of manufacturing efficiency. The Nelson-Farrar refinery operations index dropped 5.4 points, from 395.1 to 389.7 in the 1990-1991 period. The process unit index also showed a decrease over this period, dropping from 469.3 to 405.2

    2015-01-01

    The axion and m u =0 solutions to the strong CP problem have been subject to the most careful scrutiny and critique. Basic theoretical issues include hierarchy and fine-tuning problems, quality and genericity of symmetries, and compatibility with solutions to the electroweak hierarchy problem. We study the similar set of challenges for solutions to strong CP based on spontaneous CP violation and the Nelson-Barr mechanism. Some of our observations have appeared in the literature previously, and others are new; our purpose is to collect and analyze the issues as a whole and provide an assessment of the most plausible settings for the Nelson-Barr solution.

    The Nelson Hamiltonian is unitarily equivalent to a Hamiltonian defined through a closed, semibounded quadratic form, the unitary transformation being explicitly known and due to Gross. In this paper, we study the mapping properties of the Gross-transform in order to characterize the regularity properties of vectors in the form domain of the Nelson Hamiltonian. Since the operator domain is a subset of the form domain, our results apply to vectors in the domain of the Hamiltonian as well. This work is a continuation of our previous work on the Fröhlich Hamiltonian.

    This paper presents our 18 years of experience in treating ACTH secreting adenomas (Cushing's disease and Nelson's syndrome) using the Leksell gamma knife (LGK) irradiation. Twenty-six patients with Cushing's disease were followed-up after LGK irradiation for 48-216 months (median 78 months). Seventeen patients had undergone previous surgery, in nine patients LGK irradiation was the primary therapy. Furthermore, 14 patients with Nelson's syndrome were followed-up for 30-204 months (median 144 months). LGK treatment resulted in hormonal normalization in 80.7 % of patients with Cushing's disease. Time to normalization was 6-54 months (median 30 months). The volume of the adenoma decreased in 92.3% (in 30.7% disappeared completely). There was no recurrence of the disease. In all 14 patients with Nelson's syndrome ACTH levels decreased (in two patients fully normalized) their ACTH levels. When checked up 5-10 years after irradiation regrowth of the adenoma was only detected in one patient (9.1%), in 27.3% adenoma volume remained unchanged, in 45.4% adenoma volume decreased and in 18.2% adenoma completely disappeared. Hypopituitarism did not develop in any patient where the critical dose to the pituitary and distal infundibulum was respected. LGK radiation represents an effective and well-tolerated option for the treatment of patients with Cushing's disease after unsuccessful surgery and may be valuable even as a primary treatment in patients who are not suitable for, or refuse, surgery. In the case of Nelson's syndrome it is possible to impede tumorous growth and control the size of the adenoma in almost all patients.

Most of the population passes through Nelson Lagoon in spring and fall, with over 40,000 birds recorded there (Gill et al 1981). Little is known about the feeding activity of Emperor Geese while they are in estuaries, and the importance of estuaries as staging areas during spring and fall migration is poorly understood. Here I report observations on the feeding activity of emperor Geese at one estuary (Nelson Lagoon).

  19. Mercury in Nelson's Sparrow subspecies at breeding sites.

    Directory of Open Access Journals (Sweden)

    Virginia L Winder

    Full Text Available BACKGROUND: Mercury is a persistent, biomagnifying contaminant that can cause negative effects on ecosystems. Marshes are often areas of relatively high mercury methylation and bioaccumulation. Nelson's Sparrows (Ammodramus nelsoni use marsh habitats year-round and have been documented to exhibit tissue mercury concentrations that exceed negative effects thresholds. We sought to further characterize the potential risk of Nelson's Sparrows to mercury exposure by sampling individuals from sites within the range of each of its subspecies. METHODOLOGY/PRINCIPAL FINDINGS: From 2009 to 2011, we captured adult Nelson's Sparrows at sites within the breeding range of each subspecies (A. n. nelsoni: Grand Forks and Upham, North Dakota; A. n. alterus: Moosonee, Ontario; and A. n. subvirgatus: Grand Manan Island, New Brunswick and sampled breast feathers, the first primary feather (P1, and blood for total mercury analysis. Mean blood mercury in nelsoni individuals captured near Grand Forks ranged from 0.84 ± 0.37 to 1.65 ± 1.02 SD ppm among years, between 2.0 and 4.9 times as high as concentrations at the other sites (P<0.01. Breast feather mercury did not vary among sites within a given sampling year (site means ranged from 0.98 ± 0.69 to 2.71 ± 2.93 ppm. Mean P1 mercury in alterus (2.96 ± 1.84 ppm fw was significantly lower than in any other sampled population (5.25 ± 2.24-6.77 ± 3.51 ppm; P ≤ 0.03. CONCLUSIONS/SIGNIFICANCE: Our study further characterized mercury in Nelson's Sparrows near Grand Forks; we documented localized and potentially harmful mercury concentrations, indicating that this area may represent a biological mercury hotspot. This finding warrants further research to determine if wildlife populations of conservation or recreational interest in this area may be experiencing negative effects due to mercury exposure. We present preliminary conclusions about the risk of each sampled population to mercury exposure.

    Much of the literature on the history of the prediction and discovery of the Cosmic Microwave Background Radiation (CMBR) is incorrect in some respects. I focus on the early history of the CMBR, from its prediction in 1948 to its measurement in 1964, basing my discussion on the published literature, the private papers of Ralph A. Alpher, and interviews with several of the major figures involved in the prediction and measurement of the CMBR. I show that the early prediction of the CMBR continues to be widely misunderstood.

    Let ψ t , ψ t n , n≥1, be solutions of Schroedinger equations with potentials form-bounded by -1/2 Δ and initial data in H 1 (R d ). Let P, P n , n≥1, be the probability measures on the path space Ω=C(R + , R d ) given by the corresponding Nelson diffusions. We show that if {ψ t n } n≥1 converges to ψ t in H 2 (R d ), uniformly in t over compact intervals, then {P n } n≥1 converges to P in total variation. Moreover, if the potentials are in the Kato class K d , we show that the above result follows from H 1 -convergence of initial data, and K d -convergence of potentials. (orig.)

    Full Text Available This paper aims to retrace the influence of the politics of gender enacted by Nelson and Winnie Mandela on post-apartheid gender relationships, as represented in three novels: Phaswane Mpe’s Welcome to Our Hillbrow (2001, Njabulo Ndebele’s The Cry of Winnie Mandela (2003 and Lewis Nkosi’s Mandela’s Ego (2006. Recently, Nelson and Winnie Mandela’s marriage has been also described as the “unusual founding-family romance” (Munro 2014 of the post-apartheid nation. Their marriage lasted from 1958 to 1992, including, thus, the last decades of the anti-apartheid struggle, as well as the demise of the apartheid regime. Their separation, which was due in the first place to Nelson Mandela’s imprisonment and, later, to their divorce, eventually marked the disruption of this founding-family romance, making it “unusual”. As a consequence, the deconstructive take on Nelson Mandela’s fatherhood and masculinity and Winnie Mandela’s femininity and motherhood which is enacted in the three novels also allows to reassess the possibility of that “founding-family romance”, envisioning an alternative understanding of the origins of the post-apartheid South African nation.

  7. The Ralph review - tax reform and the Australian gas industry

    International Nuclear Information System (INIS)

    Horden, P.; Kellock, I.

    1999-01-01

    The impact of the Federal Government's tax reform package on the Australian gas industry will be generally negative, particularly in terms of infrastructure investment, according to Pricewaterhouse Coopers' Peter Hordern and Ian Kellock. This article examines the critical aspects of the package. Overall, the impact of the tax reform package (consisting of the Ralph committee's report and the Government's initial response) on the Australian gas industry would appear to be negative. The removal of accelerated depreciation and the potential for severe limitations on leasing arrangements is particularly bad news. While the proposed reduction in the company tax rate may appear positive, this is unlikely to provide significant benefit to the industry. The reality is existing gas infrastructure investors are generally in tax losses and will derive no immediate benefit from the rate change. For new investors, the reduction in rate will not offset the loss of accelerated depreciation deductions

    This paper explores the political, economic, and social life of Nelson Mandela through his food choices from 1918 to the present. A description of the minutiae of one particular 1950s Sunday lunch is used to examine the broader role of first colonial and later apartheid legislation in determining the dietary choices and options of South Africans past and present. How such policies shaped attitudes and access to Nelson Mandela’s ancestral Xhosa cuisine is assessed. The long-term cultural, economic, and political impact of a lack of access to core indigenous African ingredients is evaluated. Most of all this paper offers a snapshot portrayal of two families (one white, one black) trying to sustain a normal friendship within a grossly abnormal society.

    Craig, Douglas; Chartrand, Daniel

    2014-03-01

    The timing of the earliest reported ether anesthetics in early 1847, in regions to become Canada in July 1867, was examined using information from on-line and library-based sources. Previous authors had identified the first reported ether anesthetic given by a visiting American dentist in January 1847 in Saint John, New Brunswick. Nevertheless, they had reported three different anesthetics as the second occurrence - which would denote the first anesthetic given by a resident of Canada. We confirmed that there were no reports of ether anesthetics being given in Canada before that reported on January 18, 1847 in Saint John. The information available for our review indicates that the second ether anesthetic, and the first by a Canadian, was given in Montreal by a dentist, Dr. John Horatio Webster, on February 20, 1847. The surgical assistant for that operation, Dr. Horace Nelson, later reported on animal and human experiments with ether, which he had led in Montreal starting in January 1847. Earlier authors, who may not have had access to the information now available, came to incorrect conclusions about the first ether anesthetic reported to have been given by a Canadian. Current information indicates that John Webster gave the first reported anesthetic in Montreal on February 20, 1847 following experiments with ether led by Horace Nelson. Both Webster and Nelson deserve recognition as Canadian anesthesia pioneers.

  13. Preliminary report on the Nelson and Radovan copper prospects, Nizina district, Alaska

    Sainsbury, C.J.

    1952-01-01

    Renewed copper exploration by Alaska Copper Mines, Incorporated, at the Nelson and Radovan prospects, Nizina district, Alaska, led the Geological Survey in 1951 to map in detail the Nelson fault block, and to re-examine the old workings. In addition, two new prospects were studied. The Nelson fault block is cut by many dominantly strike-slip faults of small displacement, and by bedding faults. Slickensided chalcocite shows post-mineral movement, and chalcocite veinlet in a filled solution cavity indicates that some of the chalcocite is secondary, perhaps very recent. Structural relations indicate two overthrust faults cut the block. The Radovan Greenstone prospect shows massive chalcocite, up to 3 feet wide, in a silicified, epidotized fault zone in the Nikolai greenstone. Ore indicated by surface exposures may amount to 450 tons of chalcocite. The Radovan Low-Contact prospect is on a continuation of the same fault approximately 3 miles southwest of the Greenstone prospect, and 150 feet above the contact of the Nikolai greenstone and the overlying Chitistone limestone. Limonite staining is widespread in bedding planes and small faults near the fault zone; mineralization in the fault zone consists of pyrite, chalcocite, bornite, malachite, realgar, orpiment and stibnite. The sulphides in the fault zone, plus the widespread silicification and epidotization indicate a strong zone of hydrothermal activity which merits extensive prospecting.

  14. Mixing and photoreactivity of dissolved organic matter in the Nelson/Hayes estuarine system (Hudson Bay, Canada)

    Guéguen, C.; Mokhtar, M.; Perroud, A.; McCullough, G.; Papakyriakou, T.

    2016-09-01

    This work presents the results of a 4-year study (2009-2012) investigating the mixing and photoreactivity of dissolved organic matter (DOM) in the Nelson/Hayes estuary (Hudson Bay). Dissolved organic carbon (DOC), colored DOM, and humic-like DOM decreased with increasing salinity (r2 = 0.70-0.84). Removal of DOM was noticeable at low to mid salinity range, likely due to degradation and/or adsorption to particles. DOM photobleaching rates (i.e., decrease in DOM signal resulting from exposure to solar radiation) ranged from 0.005 to 0.030 h- 1, corresponding to half-lives of 4.9-9.9 days. Dissolved organic matter from the Nelson and Hayes Rivers was more photoreactive than from the estuary where the photodegradation of terrestrial DOM decreased with increasing salinity. Coincident with the loss of CDOM absorption was an increase in spectral slope S, suggesting a decrease in DOM molecular weight. Marked differences in photoreactivity of protein- and humic-like DOM were observed with highly humidified material being the most photosensitive. Information generated by our study will provide a valuable data set for better understanding the impacts of future hydroelectric development and climate change on DOM biogeochemical dynamics in the Nelson/Hayes estuary and coastal domain. This study will constitute a reference on terrestrial DOM fate prior to building additional generating capacity on the Nelson River.

    2011-01-01

    We present an extension of Nelson's stochastic quantum mechanics to finite temperature. Utilizing the formulation of Thermo Field Dynamics (TFD), we can show that Ito's stochastic equations for tilde and non-tilde particle positions reproduce the TFD-type Schroedinger equation which is equivalent to the Liouville-von Neumann equation. In our formalism, the drift terms in the Ito's stochastic equation have the temperature dependence and the thermal fluctuation is induced through the correlation of the non-tilde and tilde particles. We show that our formalism satisfies the position-momentum uncertainty relation at finite temperature. -- Highlights: → Utilizing TFD, we extend Nelson's stochastic method to finite temperature. → We introduce stochastic equations for tilde and non-tilde particles. → Our stochastic equations can reproduce the TFD-type Schroedinger equation. → Our formalism satisfies the uncertainly relation at finite temperature.

  3. The search for a more human face for Nelson Mandela: An urgent task

    2015-08-01

    Full Text Available For many reasons, reflecting on the life of Nelson Mandela is a precarious exercise. If Mandela is a symbol of the resilience of the human spirit under trying conditions, he is also a symbol that is appropriated in various ways – helpful and unhelpful – by various people. This article explores some of the unhelpful ways in which the name and person of Nelson Mandela is invoked. In particular, the article looks at the hagiographical orientation of several reflections on Mandela, cautioning how some of these may have an effect less noble than originally intended. Accordingly, the article asks: How much can the symbol of Mandela bear? How much more can Mandela give? The logic and rationale of Mandela hagiography is explored. Following his death, there has been an explosion of interest in the life and symbol that is Nelson Mandela. Mandela literature, including multi-media, is on the rise. If the symbol of Mandela is in danger of being ‘cannibalised’, there is also a danger of relegating Mandela to an ahistorical mythical figure. The solution lies in at least two area, namely, the increment of alternative Mandela narratives and the introduction of more critical Mandela narratives. In this regard, Mandela’s own self-understanding as captured in his reflections about his life offer several clues which are explored in this article.

    Full Text Available “In the late 1980s, Nelson Mandela stood alone against the apartheid state.” This comment taken from the DVD Box set cover of Nelson Mandela: From Freedom to History summarises the approach taken by many of the cinematic and televisual representations of Mandela. Linked with this is a statement by the CEO of Marriott which speaks of Mandela as “an individual who changed the arc of history through his or her singular contribution, not as a function of the era or the movement but because of what they did alone.” Together, these descriptions attempt to appropriate Mandela for a sanitised version of western individualism which sees him variously as a liberal icon, saintly hero, or the celebrity one-off “magic negro”, in Okwongo’s damning phrase taken from his magisterial valedictory piece “Mandela will never, ever be your minstrel” (Okwongo 2013. In the process, Mandela’s role in the anti-apartheid...

  8. Nelson River and Hudson Bay

    Rivers that empty into large bodies of water can have a significant impact on the thawing of nearshore winter ice. This true-color Moderate Resolution Imaging Spectroradiometer (MODIS) image from May 18, 2001, shows the Nelson River emptying spring runoff from the Manitoba province to the south into the southwestern corner of Canada's Hudson Bay. The warmer waters from more southern latitudes hasten melting of ice near the shore, though some still remained, perhaps because in shallow coastal waters, the ice could have been anchored to the bottom. High volumes of sediment in the runoff turned the inflow brown, and the rim of the retreating ice has taken on a dirty appearance even far to the east of the river's entrance into the Bay. The sediment would have further hastened the melting of the ice because its darker color would have absorbed more solar radiation than cleaner, whiter ice.

  9. Relativism: Protagoras and Nelson Goodman

    Directory of Open Access Journals (Sweden)

    2015-12-01

    Full Text Available Discussion of the many faces of relativism occupies a highly prominent place in the epistemological literature. Protagoras in ancient Greece and Nelson Goodman in the modern period are two most notable proponent of relativism. In the present article, I discuss and explain relativistic approaches of this two important relativist. I will first briefly define and review some faces of relativism. Then I will discuss and elaborate Protagorean or true-for-me relativism and Goodman’s radical relativism in turn. I will argue that there are crucial difficulties in Protagorean and radical relativism, and that these difficulties, as the realist philosophers insist, make these two faces of relativism be undefensible. No doubt, these two shapes of relativism have paved the way for anti-realism. In the end, it will appear that Goodman’s radical relativism and so the theory of worldmaking, like Protagorean relativism, suffers from a fatal flaw: the flaw of self-refuting.

    1990-01-01

    Fisheries studies on the lower Nelson River (Manitoba) system have had the goals of gaining an understanding of the fisheries resources present, assessing current and potential impacts of hydroelectric developments, and investigating enhancement or mitigative options. In 1988, a resource inventory of McMillan and 12-Mile Creeks was conducted to increase understanding of brook trout stocks in the Limestone River system. Results indicate that both streams contain self-sustaining populations. Baseline data collection in the Conawapa Forebay of the Nelson River was initiated in 1988. Inventories of fish populations were conducted, focusing on lake sturgeon. Three long-term monitoring projects were continued in 1988, investigating the populations of spawning brook trout, larval brook trout, and anadromy in brook trout. Four major tributaries to the Nelson River were classified on the basis of physical and chemical characteristics in an attempt to understand brook trout distribution patterns. Ten sturgeon were captured in Angling Lake in 1988 and fitted with radio tags to assess the importance of the Angling Lake-Angling River system to Nelson River lake sturgeon. To investigate the feasibility of enhancing brook trout populations in the Nelson River system, baskets of eggs were planted in previously identified spawning areas in three creeks in 1988. The eggs developed and hatched only in CN Creek. The potential for rehabilitating the Kettle River brook trout population by transfer of fish from other rivers was also investigated in 1988. Radio-tagged fish remained in the Kettle River-Long Spruce system throughout the life of the tags and appear to have found suitable summer and winter habitat. 60 refs., 76 figs., 38 tabs

    Full Text Available BACKGROUND: Nelson's, Saltmarsh, and Seaside Sparrows (Ammodramus nelsoni, A. caudacutus, and A. maritimus, respectively depend on marsh and wetland habitats--ecosystems in which mercury (Hg bioavailability is notoriously high. The purpose of the present study was to address the potential impact of Hg on these species using first primary and breast feathers as non-destructive biomonitoring tools. METHODS AND PRINCIPAL FINDINGS: Feathers were sampled from wintering sparrows in North Carolina salt marshes (2006-2010. Feather Hg data were used in three risk analysis components (1 Threshold Component--examined feather Hg with regard to published negative effects thresholds; (2 Hg Dynamics Component--examined Hg in sparrows captured multiple times; and (3 Capture Frequency and Survival Component--tested for links between Hg and return frequency and survival. Threshold Component analyses indicated that Hg concentrations in 42-77% of sampled individuals (breast feather n = 879; first primary feather n = 663 were within the range associated with decreased reproduction in other avian species. Hg Dynamics Component analyses demonstrated that Hg increased between first and second captures for Nelson's (n = 9 and Seaside Sparrows (n = 23. Capture Frequency and Survival Component analyses detected a negative relationship between Hg and capture frequency in Nelson's Sparrows (n = 315. However, MARK models detected no effect of Hg on apparent survival in any species. CONCLUSION AND SIGNIFICANCE: This study indicates that current Hg exposure places a considerable proportion of each population at risk. In particular, 52% of all sampled Saltmarsh Sparrows exhibited first primary feather Hg concentrations exceeding those associated with a >60% reduction in reproductive success in other species. This study reports evidence for net annual bioaccumulation, indicating an increased risk in older individuals. These data can be used to inform future population

    The hypophyses of 13 patients with Nelson syndrome following bilateral adrenalectomy were examined by MRI and CT. Diffuse enlargement of the hypophysis was demonstrated in 8 patients by CT and in 9 by MRI. Compared with CT, MRI provides better demonstration of tumour development, such as abnormal convexity of the cranial margin of the hypophysis (MRI 4/13, CT 1/13), displacement of the infundibulum (MRI 4/13, CT 0/13) or optic chiasm (MRI 2/13, CT 0/13). MRI also provides diagnostically important differentiation between scar tissue and recurrence of tumour following hypophysectomy (MRI 1/3, CT 0/3) and more accurate demonstration of infiltration of the cavernous sinus (MRI 4/13, CT 2/13). CT is superior only in showing the floor of the sella. MRI is the method of choice for imaging in cases of Nelson syndrome. (orig.) [de

    Davidson, M.

    1980-01-01

    The generalized Fenyes-Nelson model of quantum mechanics is applied to the free scalar field. The resulting Markov field is equivalent to the Euclidean Markov field with the times scaled by a common factor which depends on the diffusion parameter. This result is consistent with Guerra's earlier work on stochastic quantization of scalar fields. It suggests a deep connection between Euclidean field theory and the stochastic interpretation of quantum mechanics. The question of Lorentz covariance is also discussed. (orig.)

    A factor rotation scheme is applied to the well-known Dynamic Nelson-Siegel model facilitating direct parametrization of the short rate process. The model-implied term structure of term premia is derived in closed-form, and macroeconomic variables are included in a Taylor-rule- type fashion. Four empirical experiments are performed on US data covering the period from 1990 to 2014. It is found that macroeconomic variables impact the evolution of the short rate until 2002, after which their eff...

    We prove that a Symanzik--Nelson positive quantum field theory, i.e., a quantum field theory derived from a Euclidean field theory, has a unique decomposition into pure phases which preserves Symanzik--Nelson positivity and Poincare covariance. We derive useful sufficient conditions for the breakdown of an internal symmetry of such a theory in its pure phases, for the self-adjointness and nontrivially (in the sense of Borchers classes) of its quantum fields, and the existence of time-ordered and retarded products. All these general results are then applied to the P (phi) 2 and the phi 3 4 quantum field models

    2009-01-01

    NASA Structures engineers submitted two Nelson refractory studs from the main flame deflector at Launch Complex (LC) 39 A for analysis when they were observed to be missing a significant amount of material after launch. The damaged stud and an unused comparative stud were analyzed by macroscopic and microscopic examination along with metallographic evaluation of the microstructure. The stud lost material due to a combination of erosion and corrosion. Plain carbon steel readily forms an oxide layer in the coastal launch environment at Kennedy Space Center. The blast during a launch removes this brittle oxide layer, which then forms again post-launch, thereby further removing material. No indications of melting were observed.

  20. A hermeneutical reading of Penrose and Nelson and Winter-Tracing origins of a misunderstanding?

    2010-05-01

    Full Text Available This paper aims to understand based on a hermeutical reading of Penrose (1959 and Nelson and Winter (1982 what knowledge is and where it is stored in the respective authors. Furthermore, the author wants to learn whether the subsumtion of Knowledge Integration to Knowledge Management, as it can be often in the literature, has any foundation when coming from these authors. Reason for this overall analysis is the widely held view in the discipline of Knowledge Management that these authors are forefathers for it. Based on an interpretative, qualitative approach the author examines the way in which knowledge is held and created within organisations in the main work of this pair of author. The author comes to the conclusion that the discipline of Knowledge Management has seemingly overemphasised certain elements in the work of Penrose and Nelson and Winter, while neglecting the key aspect that for both author(s the act of Knowledge Integration is much rather described in these works.

  1. Hydrology signal from GRACE gravity data in the Nelson River basin, Canada: a comparison of two approaches

    2018-03-01

    The Gravity Recovery and Climate Experiment (GRACE) satellite mission measures the combined gravity signal of several overlapping processes. A common approach to separate the hydrological signal in previous ice-covered regions is to apply numerical models to simulate the glacial isostatic adjustment (GIA) signals related to the vanished ice load and then remove them from the observed GRACE data. However, the results of this method are strongly affected by the uncertainties of the ice and viscosity models of GIA. To avoid this, Wang et al. (Nat Geosci 6(1):38-42, 2013. https://doi.org/10.1038/NGEO1652; Geodesy Geodyn 6(4):267-273, 2015) followed the theory of Wahr et al. (Geophys Res Lett 22(8):977-980, 1995) and isolated water storage changes from GRACE in North America and Scandinavia with the help of Global Positioning System (GPS) data. Lambert et al. (Postglacial rebound and total water storage variations in the Nelson River drainage basin: a gravity GPS Study, Geological Survey of Canada Open File, 7317, 2013a, Geophys Res Lett 40(23):6118-6122, https://doi.org/10.1002/2013GL057973, 2013b) did a similar study for the Nelson River basin in North America but applying GPS and absolute gravity measurements. However, the results of the two studies in the Nelson River basin differ largely, especially for the magnitude of the hydrology signal which differs about 35%. Through detailed comparison and analysis of the input data, data post-processing techniques, methods and results of these two works, we find that the different GRACE data post-processing techniques may lead to this difference. Also the GRACE input has a larger effect on the hydrology signal amplitude than the GPS input in the Nelson River basin due to the relatively small uplift signal in this region. Meanwhile, the influence of the value of α , which represents the ratio between GIA-induced uplift rate and GIA-induced gravity-rate-of-change (before the correction for surface uplift), is more obvious in

    2014-11-01

    Full Text Available This qualitative documentary analysis examines Nelson Mandela�s defence statement at the Rivonia Trial, Pretoria Supreme Court, on 20 April 1964. The defence document is analysed through the psychological capital lens, depicting themes that support the constructs of hope, efficacy, resilience and optimism. Psychological capital characteristics played a major role in the initial non-violent policies of negotiation. The inevitable establishment of Umkhonto we Sizwe followed, as a result of the increased restrictions and unwillingness of government to negotiate and collaborate. Mandela showed a determined spirit to unite the country. The discussion gives insight into Mandela�s authentic psychological capital leadership under difficult political and personal circumstances. Some implications are indicated in adopting Mandela�s psychological characteristics for personal reform.

    Full Text Available Sweet potato cultivar Cilembu, kind of ‘rancing’ from Cilembu Village, Sumedang, West Java has really sweet taste due to the high content of reducing sugar. The amount of reducing sugar needs to be proven scientifically. The study aimed to compare Somogyi-Nelson method and Anthrone-Sulfate method in order to determine reducing sugar level in Cilembu sweet potato. Cilembu sweet potato must be stored in freezer at 15°C for 2 weeks before used as the sample. Analytical method validation was performed for the two methods. The determination results between two methods were compared. The amount of reduction sugar (glucose from Cilembu sweet potato determined by Somogyi-Nelson method was 3.42%, the value of %recovery was 99.8%, LOD = 0.00167 (mg/mL, LOQ = 0.00557 (mg/mL, and value of RSD was 3.7%. While the average amount of reduction sugar determined by Anthrone-Sulfate method was 14.9%, the value of %recovery was 74.7%, LOD = 0.0198 (mg/mL, LOQ = 0.066 (mg/mL, and value of RSD = 8.6%. The Somogyi-Nelson method was more recommended for the analysis of the reducing sugar in Cilembu sweet potato compared with Anthrone-Sulfate method.

    1983-05-01

    It is shown that by applying Nelson's stochastic quantization scheme to free linearized gravitational field tensor one can associate with the resulting stochastic system a stochastic tensor field which coincides with the ''space'' part of the Riemannian tensor in Euclidean space-time. However, such a stochastic field fails to satisfy the Markov property. Instead, it satisfies the reflection positivity. The Markovian structure of the stochastic fields associated with the electromagnetic field is also discussed. (author)

    2014-11-01

    Low-dose CT screening is recommended for individuals at high risk of developing lung cancer. However, CT screening does not detect all lung cancers: some might be missed at screening, and others can develop in the interval between screens. The NELSON trial is a randomised trial to assess the effect of screening with increasing screening intervals on lung cancer mortality. In this prespecified analysis, we aimed to assess screening test performance, and the epidemiological, radiological, and clinical characteristics of interval cancers in NELSON trial participants assigned to the screening group. Eligible participants in the NELSON trial were those aged 50-75 years, who had smoked 15 or more cigarettes per day for more than 25 years or ten or more cigarettes for more than 30 years, and were still smoking or had quit less than 10 years ago. We included all participants assigned to the screening group who had attended at least one round of screening. Screening test results were based on volumetry using a two-step approach. Initially, screening test results were classified as negative, indeterminate, or positive based on nodule presence and volume. Subsequently, participants with an initial indeterminate result underwent follow-up screening to classify their final screening test result as negative or positive, based on nodule volume doubling time. We obtained information about all lung cancer diagnoses made during the first three rounds of screening, plus an additional 2 years of follow-up from the national cancer registry. We determined epidemiological, radiological, participant, and tumour characteristics by reassessing medical files, screening CTs, and clinical CTs. The NELSON trial is registered at www.trialregister.nl, number ISRCTN63545820. 15,822 participants were enrolled in the NELSON trial, of whom 7915 were assigned to low-dose CT screening with increasing interval between screens, and 7907 to no screening. We included 7155 participants in our study, with

    An alternative explanation for unusually high ratios of oxidizers/plutonium in the residues from plutonium droplet combustion is offered in response to a note by L.S. Nelson. Two additional experiments are suggested that would be helpful in clarifying the high oxidizer/Pu ratios. The first would be to measure the true surface area for a spherule after its explosion. The second is an experiment analogous to a gas analysis experiment. The conclusion is put forth that adsorbed gases are the most likely cause of the high O/M ratios described by Nelson

    At this time in history, I consider myself very privileged to have spent some three hours in the presence of President Nelson Mandela as a Howard University faculty member in the late 1990s. Then, President of Howard University, H. Patrick Swygert bestowed upon President Nelson Mandela, Esquire an Honorary Doctorate of Human Letters. I can only equate this experience to my four mile walk up the Bedaling Wall (Great Wall) in China (a magnificent ancient wonder of the world), and trying to relate this event to something only fortunate souls have had the chance to enjoy. I also treasure the once in a lifetime visit to the Republic of South Africa in 1998 when the Association of Black Nursing Faculty, Inc., Chi Eta Phi Nursing Sorority, Inc., and the Department of Nursing (University of Botswana) sponsored the trip as an attempt to establish partnerships, share common interests and discussion in how to meet health needs of emerging majority and disadvantaged populations in the world, including mainly, the continent of Africa, in the 21st century. This short memoir can only piggy-back the massive coverage in the media that began almost instantly as a long anticipated event (death of Nelson Mandela), but startled upon its occurrence.

  12. Representation theory of Lie-admissible enveloping algebras on operator algebras: an extension of a theorem by Nelson

    This mathematical note is motivated by an assessment concerning our current understanding of the role of Lie-admissible symmetries in connection with quantum structures. We identify the problem of representations of the universal enveloping (lambda, μ)-mutation algebra of a given Lie algebra on a suitable algebra of operators, as constituting a fundamental first step for improving the situation. We acknowledge a number of difficulties which are peculiar to the adopted nonassociative product for the operator algebra. In view of these difficulties, we are presently content in establishing the generalization, to the Lie-admissible case, of a certain theorem by Nelson. This theorem has been very instrumental in Nelson's treatment concerning the Lie symmetry content of quantum structures. It is hoped that a similar situation will eventually prevail for the Lie-admissible case. We offer a number of relevant suggestions

  14. On the Reconciliation of the Extended Nelson-Siegel and the Extended Vasicek Models (with a View Towards Swap and Swaption Valuation)

    Jørgensen, Peter Løchte

    Extended Nelson-Siegel models are widely used by e.g. practitioners and central banks to estimate current term structures of riskless zero-coupon interest rates, whereas other models such as the extended Vasicek model (a.k.a. the Hull-White model) are popular for pricing interest rate derivatives....... This paper establishes theoretical consistency between these two types of models by showing how to specify the extended Vasicek model such that its implied initial term structure curve precisely matches a given extended Nelson-Siegel specification. That is, we show how to reconcile the two classes of models...

    Ahmed, A.Z.

    2011-01-01

    The aim of this work is to study modeling of chromium (III) removal from aqueous solution using activated carbon as adsorbent. Studies have been conducted in a continuous fixed bed packed column under different operating conditions such as bed height, flow rate, fluid velocity and fixed adsorbent particle size. The Yoon Nelson model was applied to experimental data to predict the breakthrough curves by calculating the rate constant k and 50 % breakthrough time, θ. The Bed Depth Service Time (BDST) was applied to determine BDST constant K and the capacity of adsorbent, No. Results obtained from both models are compared with the experimental breakthrough curves and a satisfactory agreement was noticed. Therefore, the Yoon - Nelson and BDST models were found suitable for determining the parameters of the column design. The Y 000 - Nelson model was found more accurate in representing the system in comparison with the BDST model although it is less complicated than other models

    2003-01-01

    Ten pollen records from the Cobb Valley and adjacent areas in North-West Nelson are described. Collectively they provide a vegetation record extending from the Last Glacial Maximum to the present day. During the Last Glacial Maximum the uplands of North-West Nelson were glaciated. By about 17,000 radiocarbon years BP ice had retreated some distance up the Cobb River Valley and a podocarp heath and tussockland vegetation covered non-glaciated areas. By 14,000 radiocarbon years BP, the valley floor and adjacent lower ridges were occupied by montane podocarp forest dominated by Phyllocladus and Halocarpus. Beech forest expanded into some sites as early as 13,000 yr BP but the modern beech cover was not established until the Holocene. Forest cover has fluctuated in response to disturbance over the Holocene, but the most significant recent change, which is related to clearing for pastoralism in the last two centuries, has had surprisingly little impact on the pollen records.

    Nelson's syndrome is a unique clinical phenomenon of growth of a pituitary adenoma following bilateral adrenalectomies for the control of Cushing's disease. Primary management is surgical, with limited effective medical therapies available. We report our own institution's series of this pathology managed with radiation: prior to 1990, 12 patients were managed with conventional radiotherapy, and between 1990 and 2007, five patients underwent stereotactic radiosurgery (SRS) and two patients fractionated stereotactic radiotherapy (FSRT), both using the linear accelerator (LINAC). Tumour control was equivocal, with two of the five SRS patients having a reduction in tumour volume, one patient remaining unchanged, and two patients having an increase in volume. In the FSRT group, one patient had a decrease in tumour volume whilst the other had an increase in volume. Treatment related morbidity was low. Nelson's syndrome is a challenging clinical scenario, with a highly variable response to radiation in our series. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Temperature dependences of I-V characteristics and voltage harmonics V n (T) (n = 2, 3, ...) have been investigated in magnetic fields up to 200 Oe for single crystals YBa 2 Cu 3 O 7-x . It was shown that V n (T) had asymmetric peak form with maximum at T* = 92.0 K. Amplitudes of V n (T) were decreased in magnetic fields. The results were explained on the base of the Berezinskii-Kosterlitz-Thouless (BKT) transition model. It was shown that T* coincided with the BKT transition temperature T BKT . The asymmetric peaks of V n (T) are a consequence of the Nelson-Kosterlitz jump

    1992-01-01

    A summary is presented of discussions and conclusions at a workshop held to examine the potential effects of hydroelectric development on beluga whales of the Nelson River estuary in Manitoba. Background information is provided on the estuary, beluga whales and their use of arctic and subarctic estuaries, and hydroelectric development on the Nelson River. Potential impacts of such development on the whales are reviewed in the categories of direct effects of changes in physical-chemical conditions (temperature and discharge), indirect effects of disturbances mediated through the food chain, and effects on socioeconomic conditions that may affect beluga whales. Since the biology of beluga whales and other phenomena of interest in this study are poorly known, recommendations are made for research and monitoring activities in the Nelson River estuary. In general, the workshop participants felt that changes in the estuary due to hydroelectric development would not be large enough to affect beluga whales strongly. 34 refs., 1 fig

    Ralph Robert Robbins, Jr., died on 2 December 2005, in Kyle, Texas. His wife, Maria Elena Robbins, his daughters Julia Robbins Kelso and Stephanie Juarez Balles, his son Matthew Juarez, and five grandchildren survive him. Bob was on the faculty at the University of Texas from 1968 until his retirement in 2003. Bob was born in Wichita, Kansas, on 2 September 1938, the only son of Mildred and Ralph Robert Robbins, Sr. Guided by his high school's policy to provide a practical education to children of working-class parents, Bob began high school with a heavy dose of vocational courses until the results of a test indicated his special talent in mathematics. He was awarded a full scholarship to Yale University, graduating magna cum laude in mathematics in 1960. He won the Warner Prize in Mathematics at Yale that year. He received his Ph.D. in 1966 with a dissertation entitled "The Triplet Spectrum of Neutral Helium in Expanding Nebulae" from the University of California at Berkeley. His interest in college teaching was ignited at this time through summer teaching positions at San Mateo California Junior College and the Ohio State University. Following a year at Texas as a McDonald Observatory Post-doctoral Fellow, Bob taught for a year in the physics department of the University of Houston before returning to the University of Texas at Austin as an Assistant Professor of Astronomy in 1968. He was promoted to Associate Professor in 1972. Bob's research in the early 1970s on theoretical studies of helium was of vital importance to astronomers for over three decades. These pioneering calculations became vital to observational astronomers in the mid-1990s as interest grew in the primordial helium produced by the Big Bang. Bob's interest and influence in education was international in scope. In the summers 1968-1970, he was a government consultant in Mathematics in East Pakistan (now Bangladesh). He consulted with the government that was preparing a master plan for technical

  9. Perceptions of patient-centred care at public hospitals in Nelson Mandela Bay

    Full Text Available In South Africa, the quality of health care is directly related to the concept of patient-centred care and the enactment of the Batho Pele Principles and the Patients' Rights Charter. Reports in the media indicate that public hospitals in the Eastern Cape Province are on the brink of collapse, with many patients being treated in condemned hospitals which lacked piped water, electricity and essential medical equipment. Receiving quality care, and principally patient-centred care, in the face of such challenges is unlikely and consequently leads to the following question: “Are patients receiving patient-centred care in public hospitals?” A qualitative, explorative, descriptive and contextual study was conducted to explore and describe the perceptions of professional nurses regarding patient-centred care in public hospitals in Nelson Mandela Bay. Semi-structured interviews were conducted with a total of 40 purposively selected professional nurses working in public hospitals in Nelson Mandela Bay, Eastern Cape Province. Interviews were analysed according to the method described by Tesch in Creswell (2009:192. Professional nurses perceive patient-centred care as an awareness of the importance of the patient's culture, involving the patient's family, incorporating values of love and respect, optimal communication in all facets of patient care and accountability to the patient. Factors which enable patient-centred care were a positive work environment for staff, nursing manager's demonstrating exemplary professional leadership, continuous in service education for staff and collaborative teamwork within the interdisciplinary team. Barriers to patient-centred care were a lack of adequate resources, increased administrative work due to fear of litigation and unprofessional behaviour of nursing staff.

    Glacial and fluvioglacial landforms and deposits preserved in the middle reaches of the Maruia valley, southeast Nelson, New Zealand, record the activity of the Maruia glacier during the late Pleistocene Otira Glaciation. Five advances are recognised, from oldest to youngest: Creighton 1, 2, 3, and the Reid Stream 1, 2 advances. There was an interstadial interval between the Creighton 3 and Reid Stream 1 advances. The Reid Stream 1 advance occurred shortly after 14 800 years B.P. (NZ536, old T/sub 0.5/). (auths)

    2002-04-01

    The Klein-Gordon equation is shown to be equivalent to coupled partial differential equations for a sub-quantum Brownian movement of a “particle”, which is both passively affected by, and actively affecting, a diffusion process of its generally nonlocal environment. This indicates circularly causal, or “cybernetic”, relationships between “particles” and their surroundings. Moreover, in the relativistic domain, the original stochastic theory of Nelson is shown to hold as a limiting case only, i.e., for a vanishing quantum potential.

    We consider the Bohr correspondence limit of the Schroedinger wave function for an atomic elliptic state. We analyze this limit in the context of Nelson's stochastic mechanics, exposing an underlying deterministic dynamical system in which trajectories converge to Keplerian motion on an ellipse. This solves the long standing problem of obtaining Kepler's laws of planetary motion in a quantum mechanical setting. In this quantum mechanical setting, local mild instabilities occur in the Keplerian orbit for eccentricities greater than (1/√(2)) which do not occur classically

    2014-11-01

    Full Text Available This essay analyzes Barack Obama’s Nelson Mandela Memorial speech together with other seminal texts of Obama’s political and personal creed, such as his book Dreams from My Father (1995 and his speech “A More Perfect Union” (2008. This reading becomes helpful to understand Mandela’s transnational power, which Obama uses to comment on the United States by comparing Madiba to other American “fathers of the nation.” Thus, he uproots Mandela’s from a specifically South African legacy, expands his figure, and addresses him as a transnational father of his own nation, whose power, influence, and example transcend South African borders. As a consequence of this enlargement and transnational validation of Mandela’s figure, the speech delivered at the Memorial becomes an occasion to tackle American past and future, while the memory of Madiba and his driving example in Obama’s life serve to reinforce previous positions conveyed in other discourses by the American President, such as the “A More Perfect Union” speech delivered in Philadelphia in 2008.

    The rate of caesarean section deliveries has increased globally and mothers are faced with challenges of postoperative recovery and caring thereof. Midwives have a duty to assist these mothers to self-care. The objective was to explore and describe experiences of post-caesarean section delivered mothers of midwifery care at a public hospital in Nelson Mandela Bay. A qualitative, descriptive and explorative research design was used in the study. Data were collected from 11 purposively criterion-selected mothers who had a caesarean section delivery. One-on-one semi-structured interviews were conducted in the post-natal wards. Research ethics, namely autonomy, beneficence, justice and informed consent, were adopted in the study. All participants were informed of their right to withdraw from the study at any stage without penalties. Interviews were analysed using Tesch's method of data analysis. Three main themes were identified as experiences of: diverse pain, physical limitation and frustration and health care services as different. Experiences of mothers following a caesarean section delivery with midwifery services at a public hospital in Nelson Mandela Bay were explored and described as diverse. A need for adequate pain management as well as assistance and breastfeeding support to mothers following caesarean delivery was identified as crucial to promote a good mother-to-child relationship.

  1. Conservative diffusions: a constructive approach to Nelson's stochastic mechanics

    International Nuclear Information System (INIS)

    Carlen, E.A.

    1984-01-01

    In Nelson's stochastic mechanics, quantum phenomena are described in terms of diffusions instead of wave functions; this thesis is a study of that description. Concern here is with the possibility of describing, as opposed to explaining, quantum phenomena in terms of diffusions. In this direction, the following questions arise: ''Do the diffusion of stochastic mechanics - which are formally given by stochastic differential equations with extremely singular coefficients - really exist.'' Given that they exist, one can ask, ''Do these diffusions have physically reasonable paths to study the behavior of physical systems.'' These are the questions treated in this thesis. In Chapter 1, stochastic mechanics and diffusion theory are reviewed, using the Guerra-Morato variational principle to establish the connection with the Schroedinger equation. Chapter II settles the first of the questions raised above. Using PDE methods, the diffusions of stochastic mechanics are constructed. The result is sufficiently general to be of independent mathematical interest. In Chapter III, potential scattering in stochastic mechanics is treated and direct probabilistic methods of studying quantum scattering problems are discussed. The results provide a solid YES in answer to the second question raised above

    Shortly after the conviction of Nelson Mandela at the Rivonia trial in 1964, the Anti-Apartheid Movement of Geneva was created at a meeting at CERN. Arriving at CERN as Visiting Scientist in June 1966, I joined the Anti-Apartheid Movement immediately. We multiplied the initiatives at CERN and outside of CERN until the release of Mandela with citizens of Geneva, but also with "citizens of the world", who ignored the ban on political activity, particularly for international civil servants. The Anti-Apartheid Movement of Geneva soon became the Anti-Apartheid Movement of Switzerland. It was also the first Anti-Apartheid Movement outside of South Africa. CERN today is honoured to have brought it to the baptismal font thanks to the initiative of several colleagues, including Mike Pentz, president of the CERN staff Association for two years (1961  1963) and also a refugee from South Africa in Europe.

    2010-01-01

    Computational simulation of natural convection in a molten core during a hypothetical severe accident in the lower head of a typical PWR pressure vessel was performed for two-dimensional semi-circular geometry with isothermal walls. Transient turbulent natural convection heat transfer of a fluid with uniformly distributed volumetric heat generation rate was simulated by using a commercial computational fluid dynamics software ANSYS CFX 12.0. The Boussinesq model was used for the buoyancy effect generated by the internal heat source in the flow field. The two-equation k-ω based SST (Shear Stress Transport) turbulence model was used to mould the turbulent stresses in the Reynolds-Average Navier-Stokes equations (RANS). Two Prandtl numbers, 6:13 and 7:0, were considered. Five Rayleigh numbers were simulated for each Prandtl number used (109, 1010, 1011, 1012, and 1013). The average Nusselt numbers on the bottom surface of the semicircular cavity were in excellent agreement with Mayinger et al. (1976) correlation and only at Ra = 109 the average Nusselt number on the top flat surface was in agreement with Mayinger et al. (1976) and Kulacki and Emara (1975) correlations. (author)

  8. The Weathered Corrugations of His Face: A Performative Reflection on Nelson Mandela, Self, and the Call for Racial (UnBecoming

    Directory of Open Access Journals (Sweden)

    Paul Badenhorst

    2015-03-01

    Full Text Available On the occasion of the first anniversary of the death of Nelson Rolihlahla MANDELA, this self-exploratory narrative study utilizes a Butlerian performative theoretical framework to both uncover discursively regulated social practices as generative of raced identity ensconced in belonging, and the undoing of such identity through the redeployment of social practices predicated instead on a Weltanschauung of becoming. While the accountable subject of autoethnographic work is concomitantly problematized, fluid subjectivity is itself demonstrated as crucial to historical accountability. A resultant appeal for white South Africans to actively begin the work of defamiliarizing themselves with the sanitized dominant popular culture representation of the peace icon, this research ultimately calls for new existential reflection upon the face of Nelson MANDELA so as to begin uncovering its deeper historical significance, contemporary relevance, and the future ethical imperative it demands of those who come from a liminal position of, as J.M. COETZEE once wrote, "no longer European, not yet African" (1988, p.11. In short, it is argued that white South Africans need to move from a condition of belonging predicated on raced identity to one of transracial—and even interracial—African becoming.

    2014-11-01

    Full Text Available This paper aims to highlight how inspirational the figure of Nelson Mandela has been for several musicians and songwriters. In particular, it focuses on songs written by Western musicians from the early Eighties until 2013 – all showing the extent to which the South African leader has epitomized the struggle for equality and freedom. This study points out how the success of a hit single in 1984 – British ska group The Special AKA’s “Free Nelson Mandela” – paved the way for a quick increase in the number of musicians who got involved in the anti-apartheid movement and contributed to make Western audiences know about Mandela and increasingly demand that apartheid be put to an end. This survey seeks to examine the main achievements in pop-rock songs that generated both from the growing awareness about the South African leader’s experience when he was imprisoned, and the legacy of his exemplum after he was set free. Among the songs cited: Simple Minds’ “Mandela Day”, the various artists’ tribute “46664” and the most recent Golden Globe-awarded “Ordinary Love” by U2, written for the soundtrack of the biopic The Long Walk to Freedom. To better understand how the figure of Mandela has been addressed in these works, the paper includes analyses of the most complex and significant lyrics among the songs discussed, thus also showing how the South African cultural background as it was received by the West could have informed the songwriting, and how the Western reception of such songs determined an increasing awareness about Mandela’s plight and the whole phenomenon of apartheid.

    Full Text Available Various parts of sea buckthorn [Elaeagnus rhamnoides (L. A. Nelson], particularly the berries, known also as seaberries, or Siberian pineapples, are characterized by a unique composition of bioactive compounds: phenolic compounds, vitamins (especially vitamin C, unsaturated fatty acids, and phytosterols such as beta-sitosterol. These berries, together with the juices, jams, and oils made from them, have a range of beneficial antioxidant, anti-inflammatory, and anticancer effects. This short review discusses whether sea buckthorn may represent a “golden mean” for the treatment of cancers: It has anti-proliferation properties and can induce apoptosis and stimulate the immune system, and sea buckthorn oil counteracts many side effects of chemotherapy by restoring kidney and liver function, increasing appetite, and keeping patients in general good health. Although the anticancer activity of sea buckthorn has been confirmed by many in vitro and animal in vivo studies, the treatment and prophylactic doses for humans are unknown. Therefore, greater attention should be paid to the development of well-controlled and high-quality clinical experiments in this area.

    Full Text Available Comprehensive HIV and AIDS workplace programmes made use of substantial lottery incentives in HIV counselling and testing drives to promote HIV testing at four companies in the automotive industry in the Nelson Mandela Bay Municipality. The main aim was to use lottery incentives to increase uptake for HIV testing. This would help to define company HIV prevalence and ensure timely support, care and treatment of employees. In total, 1 324 employees, making up about 90% of the total staff, were tested for HIV in the four companies during wellness testing days. In order to gain an understanding of employees’ experiences of the lotteries as part of the HIV counselling and testing drive, quantitative data were collected among a total of 414 employees, and 17 interviews were conducted in the four companies. In this article, we investigate the issue of whether the lotteries unduly influenced the employees’ participation in workplace HIV testing, and an approach to resolving an identified ethical dilemma is presented. The ethical question as to whether lottery incentives contribute to undue coercion was explored using both a utilitarian and a deontological approach. The analysis concluded that the use of lotteries to encourage HIV testing in the workplaces of the automotive industry in the Nelson Mandela Bay Municipality can be deemed morally acceptable.

    2018-02-01

    Let $H_{P,\\sigma}$ be the single-electron fiber Hamiltonians of the massless Nelson model at total momentum $P$ and infrared cut-off $\\sigma>0$. We establish detailed regularity properties of the corresponding $n$-particle ground state wave functions $f^n_{P,\\sigma}$ as functions of $P$ and $\\sigma$. In particular, we show that \\[ |\\partial_{P^j}f^{n}_{P,\\sigma}(k_1,\\ldots, k_n)|, \\ \\ |\\partial_{P^j} \\partial_{P^{j'}} f^{n}_{P,\\sigma}(k_1,\\ldots, k_n)| \\leq \\frac{1}{\\sqrt{n!}} \\frac{(c\\lambda_0)^n}{\\sigma^{\\delta_{\\lambda_0}}} \\prod_{i=1}^n\\frac{ \\chi_{[\\sigma,\\kappa)}(k_i)}{|k_i|^{3/2}}, \\] where $c$ is a numerical constant, $\\lambda_0\\mapsto \\delta_{\\lambda_0}$ is a positive function of the maximal admissible coupling constant which satisfies $\\lim_{\\lambda_0\\to 0}\\delta_{\\lambda_0}=0$ and $\\chi_{[\\sigma,\\kappa)}$ is the (approximate) characteristic function of the energy region between the infrared cut-off $\\sigma$ and the ultraviolet cut-off $\\kappa$. While the analysis of the first derivative is relatively straightforward, the second derivative requires a new strategy. By solving a non-commutative recurrence relation we derive a novel formula for $f^n_{P,\\sigma}$ with improved infrared properties. In this representation $\\partial_{P^{j'}}\\partial_{P^{j}}f^n_{P,\\sigma}$ is amenable to sharp estimates obtained by iterative analytic perturbation theory in part II of this series of papers. The bounds stated above are instrumental for scattering theory of two electrons in the Nelson model, as explained in part I of this series.

    2009-10-01

    Full Text Available Riders to the Sea: An opera in one act based on the play by John Millington Synge, Ralph Vaughan Williams’s fifth opera, composed between 1925 and 1932, after The Poisoned Kiss (A Romantic Extravaganza, was first performed at London’s Royal College of Music on December 1st, 1937, with Malcolm Sargent conducting. A masterpiece of poetic intensity and a compendium of pain and quiet, resigned courage, worthy of a Greek tragedy, the Irish dramatist’s play was faithfully adapted by the composer-librettist in a work whose originality and universal message cannot fail to impress. Originating in his wide-ranging imagination―humanistic, brotherly, idealistic, universal―it speaks of a voyage of initiation to the Aran Islands, off the west coast of Ireland. The composer, inspired by folk wisdom and the world of the Spirit, open to worldly solicitations as well as to meditation, saw the play as a vehicle to highlight some aspects of his own musical heritage. In a few pages of dialogue, the score conveys a whole range of different emotions arising from the confrontation with Nature, and more particularly, from the forlorn struggle of the islanders against the sea and God, their ruler.

    Various changes in the cultural material derived from the later Holocene levels of Nelson Bay Cave can be pinpointed in temporal context by means of a large series of radiocarbon dates, such as Carbon 13 and Carbon 14 covering the past 6 000 years. As excavations and analysis of the recovered materials proceeded, radiocarbon dates were sought in order to provide a chronological frame work for what are taken to be significant features in the history of the site, and these are discussed in the article. Several pottery and assumed sheep remains were recorded. Six human burials were also recovered and this helps with the characterization of Holocene burial practices

    1983-01-01

    Approximately 14 m of sediment are exposed in a road cutting beneath a landslide deposit in the Warwick valley, southeast Nelson, New Zealand. Three radiocarbon dates and 5 pollen spectra were obtained from organic horizons in these sediments. The dates indicate that lacustrine sedimentation predominated from before 17 500 until 14 450 years ago. This was interrupted by a brief period of gravel aggradation between 17 500 and 16 650 years ago, which is attributed to a glacial advance. Vegetation at the site was consistently dominated by Cyperaceae, with some Gramineae, suggesting a bleak, treeless landscape. Correlation of this information with other radiocarbon dated sites indicates the need for some revision of the chronology of the late Otira Glaciation. A late phase of the Kumara 2 2 advance occurred between 17 000 and 16 000 years ago, and the Kumara 3 1 advance did not occur until after about 15 000 years ago. The end of the Otira Glaciation probably occurred between 13 000 and 12 500 years ago. (auth)

    Simonsohn, Nelson, and Simmons (2014) have suggested a novel test to detect p-hacking in research, that is, when researchers report excessive rates of "significant effects" that are truly false positives. Although this test is very useful for identifying true effects in some cases, it fails to identify false positives in several situations when researchers conduct multiple statistical tests (e.g., reporting the most significant result). In these cases, p-curves are right-skewed, thereby mimicking the existence of real effects even if no effect is actually present. (c) 2015 APA, all rights reserved).

El modelo de evaluación utilizado en la presente investigación fue el polinomial. El ensayo evaluó el funcionamiento del sistema de riego con 4 presiones de operación distintas, medidas a la salida de la válvula del módulo de riego, y por cada presión de operación se tomaron 16 datos de caudales, en 5 módulos de riego instalado con el aspersor autocompensado Nelson R10. Como resultado se obtuvo el coeficiente de uniformidad, el coeficiente de distribución, el área adecuadamente irrigada y el factor de adecuación del riego. Uno de los principales resultados fue la no existencia de diferencia significativa entre las presiones mientras esta se mantengan en el rango de autocompensación; por otro lado, en el coeficiente de distribución sí existen diferencias significativas entre los tratamientos, a pesar de que todos dan valores mayores al 90%, en contraste con los porcentajes del área relativa adecuadamente regada, que no superan el 50% en ninguno de los tratamientos. Con lo anterior se pudo validar y verificar que el aspersor Nelson R10 autocompensado, una vez instalado en campo, cumple con las características técnicas de operación expuestas en el catálogo del fabricante, sin embargo, sí se debe manejar y controlar la lámina de riego aplicada.

    Full Text Available http://dx.doi.org/10.5007/2176-8552.2013n16p163 A verossimilhança sempre foi amplamente explorada pela imaginação artística. Poetas trágicos e cômicos tramaram situações as mais criativas, buscando mover o público ao riso ou às lágrimas. Tradicionalmente, entretanto, recaem limites sobre as representações dramáticas, a depender dos efeitos que os autores pretendem provocar. Assim, ainda que eventos impossíveis tenham participado da tragédia desde suas origens, e ainda que o humor tenha sido ocasionalmente acolhido nas tramas, o tratamento sério da ação sempre foi exigência da forma, de maneira a que o trágico não se fizesse cômico. Com o passar dos séculos, dramaturgos desafiariam as definições de tragédia e comédia, preparando as bases para o drama social. A dramatização de conflitos da vida burguesa rapidamente absorveria um amplo espectro de tons emocionais, abolindo convenções antigas em favor de um gênero que se quer lócus privilegiado de crítica social. O trágico poderia agora ser dramatizado sob perspectivas as mais diversas, inclusive farsescas. Este ensaio examina a tragicidade na peça Dorotéia, de Nelson Rodrigues, focalizando as relações da obra com a tradição e considerando, através do conceito de “dispositivo” formulado por Agamben, estratégias utilizadas pelo dramaturgo para produzir uma crítica sarcástica a valores e instituições sociais.

    2011-10-01

    The monogeneric family Fergusoninidae consists of gall-forming flies that, together with Fergusobia (Tylenchida: Neotylenchidae) nematodes, form the only known mutualistic association between insects and nematodes. In this study, the entire 16,000 bp mitochondrial genome of Fergusonina taylori Nelson and Yeates was sequenced. The circular genome contains one encoding region including 27 genes and one non-coding A+T-rich region. The arrangement of the protein-coding, ribosomal RNA (rRNA) and transfer RNA (tRNA) genes was the same as that found in the ancestral insect. Nucleotide composition is highly A+T biased. All of the protein initiation codons are ATN, except for nad1 which begins with TTT. All 22 tRNA anticodons of F. taylori match those observed in Drosophila yakuba, and all form the typical cloverleaf structure except for tRNA-Ser((AGN)) which lacks a dihydrouridine (DHU) arm. Secondary structural features of the rRNA genes of Fergusonina are similar to those proposed for other insects, with minor modifications. The mitochondrial genome of Fergusonina presented here may prove valuable for resolving the sister group to the Fergusoninidae, and expands the available mtDNA data sources for acalyptrates overall.

    Power system reliability problems are very difficult to solve because the power systems are complex and geographically widely distributed and influenced by numerous unexpected events. It is therefore imperative to employ the most efficient optimization methods in solving the problems relating to reliability of the power system. This paper presents a reliability analysis and study of the power interruptions resulting from severe power outages in the Nelson Mandela Bay Municipality (NMBM), South Africa and includes an overview of the important factors influencing reliability, and methods to improve the reliability. The Blue Horizon Bay 22 kV overhead line, supplying a 6.6 kV residential sector has been selected. It has been established that 70% of the outages, recorded at the source, originate on this feeder.

    Obstetric haemorrhage is the leading direct cause of maternal mortality in South Africa. To determine the incidence, indications, associations and maternal outcomes of emergency peripartum hysterectomies. A descriptive and retrospective analysis of patients who had peripartum hysterectomy between 1(st) February 2007 and 31(st) January 2009 in Nelson Mandela Academic Hospital at Mthatha city. The incidence of 0.95% of peripartum hysterectomies (n=63 or 9.5/1000 births) increased with the increasing maternal age from 0.121% at age of less than 20 years to 0.5% at age more or equal to 30 years. Similarly the incidence increased with parity from 0.332% for Primiparity to 0.468% at parity of four or more. The indications for the operation were uterine atony 19/63 (30.2%), secondary haemorrhage/puerperal sepsis 17/63 (27%) and ruptured uterus 16/63 (23.4%). The main intra operative complication was haemorrhage 13/63 (20.6%). Repeat laparotomy was done in 10/63 (15%) of patients due to haemorrhage. Admission to intensive care unit was 25/63 (39.7%). The case specific mortality rate was of 19 % (n=12). The main causes of death were hypovolaemic shock and septicemia. The incidence of peripartum hysterectomies was high and was associated with ruptured uterus and puerperal sepsis which are preventable.

  20. A cinema of presence and proximity: Gunvor Nelson's collage films and the aesthetics of the signaletic material before the electronic signal

    Full Text Available This essay argues for the importance of an intersubjective and impure film theory in which the signal and the signaletic is considered as figures for approaching film. This in order to make the argument that the signaletic mode indeed enables a novel perspective on moving image history. The aesthetics of the signaletic has thus a history preceding that of electronic media, in particular when it comes to animation and experimental film. When constructing such an archaeology, however, dichotomies into sign and signal should be avoided; otherwise, the complexity of many of the films is reduced. In order to illuminate the latter point, four films by Gunvor Nelson is analyzed (both analog and digital, showing not only how both sign and signal interact but also how the aesthetics of the signal and the signaletic material is not dependant on the electronic as such.

    Background The human immunodeficiency virus and/or acquired immune deficiency syndrome (HIV/AIDS) pandemic continues to increase in prevalence worldwide, particularly in South Africa, and includes the often overlooked paediatric population. The provision of paediatric antiretroviral treatment (ART) is as essential for children as for adults, and has numerous obstacles, not least of which is lack of decentralisation of facilities to provide essential treatment. Optimising ART, care and support for HIV-positive children, and their caregivers, at public sector primary health care (PHC) clinics is crucial to improve morbidity and mortality rates in children. Aim To explore the experiences of health care professionals regarding the provision of ART for children at PHC clinics. Setting The study was conducted in six PHC clinics in Nelson Mandela Bay Health District, Eastern Cape, South Africa. Methodology The researchers used a qualitative, explorative, descriptive and contextual research design with in-depth interviews. We used non-probability purposive sampling. Data collected were thematically analysed using Creswell’s data analysis spiral. We used Lincoln and Guba’s model to ensure trustworthiness. Ethical standards were applied. Results Health care professionals experienced numerous challenges, such as lack of resources, need for training, mentoring and debriefing, all related to providing decentralised ART for HIV-positive children at the PHC level. Conclusion Capacitation of the health care system, integration of services, competent management and visionary leadership to invoke a collaborative interdisciplinary team approach is required to ensure that HIV is treated as a chronic disease at the PHC clinic level.

    Oxygen isotope measurements of ground and surface waters of the Waimea Plains, Nelson, have been used to identify sources of water in aquifers beneath the plains. Major rivers flowing onto the plains are from higher-altitude catchments (maximum altitude 2000 m) and have delta O 18 approximately equal to -7.2%, whereas rainfall on the plains and adjacent low-altitude catchment streams have delta O 18 approximately equal to -6.2%. The delta O 18 measurements indicate that the 3 major aquifer units, the ''Lower Confined Aquifers'' and the ''Upper Confined Aquifers'' in the Hope Gravel (Late Pleistocene) and the ''Unconfined Aquifers'' in the Appleby Gravel (Holocene) are recharged from different sources. The ''Lower Confined Aquifers'' probably receive slow recharge in the south near Brightwater. The ''Upper Confined Aquifers'' are recharged, in the south, from the Wairoa River and locally in the north are connected with the unconfined aquifers. The ''Unconfined Aquifers'' are recharged from the Waimea River and, away from the river, from rainfall. Intermixing of water, via multiple screened wells, between the various aquifers is also indicated. (author). 5 refs., 5 figs., 1 tab

    Appendicectomy is the most commonly performed operation worldwide. The diagnosis is predominantly based on clinical findings. Some patients will clinically be unclear if ruptured or acute inflamed appendicitis; the level of white cell count has been used as the predictor for ruptured appendicitis. This was a retrospective chart review of paediatric surgical patients admitted at Nelson Mandela Central Hospital, Mthatha South Africa. A total of 214 patients with a diagnosis of acute appendicitis. Overall, the ruptured appendicitis was 62% and 38% were inflamed appendicitis. Nature of the acute appendicitis: White cell count, Inflamed, Ruptured, Total p-value 30 0 4 4. This study has demonstrated that in patients who are diagnosed with acute appendicitis clinically, the normal white cell count does not necessarily rule out ruptured acute appendicitis. But the risks of ruptured acute appendicitis increase with the increase level of white cell count.

  7. The physics and chemistry of Earth's dynamic surface (Ralph Alger Bagnold Medal Lecture)

    2013-04-01

    Ralph Alger Bagnold became a Fellow of the Royal Society and one of the founders of modern geomorphology despite having no formal academic affiliation, no cadre of students or postdocs under his command, no steady financial support, and no scientific training beyond a second-class honors degree in engineering. What he did have, and used to great effect, were a deep curiosity about natural phenomena, a powerful physical intellect, a talent for clever experimentation, extensive opportunities to observe geomorphic processes at work in the field, and - perhaps most important of all - the time and freedom to focus his energies on significant scientific challenges. A hallmark of Bagnold's work is the artful compromise between the goal of simple, general, physical laws describing natural phenomena, and the practical necessity for observational empiricisms to account for the real-world complexities that cannot be incorporated explicitly into such simple laws. Efforts to find these sorts of artful compromises continue to the present day. Typically, both in Bagnold's work and in present-day geomorphology, one seeks mathematical process laws whose form embodies the "pure physics" of the problem, and whose coefficients subsume the inevitable observational empiricisms. Present-day geomorphologists have an array of new tools that open our eyes to temporal and spatial scales that were invisible to Bagnold and his contemporaries. These observations, in turn, have yielded new surprises and challenges, sometimes confounding our intuition about how geomorphic systems "should" behave. One surprise has been that decadal-scale erosion rates, as reflected in stream sediment loads and reservoir sedimentation rates, often differ from longer-term erosion rates by large multiples. In some agricultural landscapes, modern-day erosion rates greatly exceed the long-term background rate, as one might intuitively expect. In other landscapes, however, contemporary erosion rates can be a small

    There is uncertainty surrounding the duration, magnitude and frequency of historical hydroclimatic extremes such as hydrologic droughts and floods prior to the observed record. In regions where paleoclimatic studies are less reliable, Global Climate Models (GCMs) can provide useful information about past hydroclimatic conditions. This study evaluates the use of Coupled Model Intercomparison Project 5 (CMIP5) GCMs to enhance the understanding of historical droughts and floods across the Canadian Prairie region in the Nelson-Churchill Watershed (NCW). The NCW is approximately 1.4 million km2 in size and drains into Hudson Bay in Northern Manitoba, Canada. One hundred years of observed hydrologic records show extended dry and wet periods in this region; however paleoclimatic studies suggest that longer, more severe droughts have occurred in the past. In Manitoba, where hydropower is the primary source of electricity, droughts are of particular interest as they are important for future resource planning. Twenty-three GCMs with daily runoff are evaluated using 16 metrics for skill in reproducing historic annual runoff patterns. A common 56-year historic period of 1950-2005 is used for this evaluation to capture wet and dry periods. GCM runoff is then routed at a grid resolution of 0.25° using the WATFLOOD hydrological model storage-routing algorithm to develop streamflow scenarios. Reservoir operation is naturalized and a consistent temperature scenario is used to determine ice-on and ice-off conditions. These streamflow simulations are compared with the historic record to remove bias using quantile mapping of empirical distribution functions. GCM runoff data from pre-industrial and future projection experiments are also bias corrected to obtain extended streamflow simulations. GCM streamflow simulations of more than 650 years include a stationary (pre-industrial) period and future periods forced by radiative forcing scenarios. Quantile mapping adjusts for magnitude

    Sediment cores were sampled in the estuary of the Nelson and Churchill Rivers in western Hudson Bay, as well as in the estuary of the Moisie and Sainte-Marguerite Rivers in Gulf of St. Lawrence in order to evaluate the impact of hydroelectric dams on the sedimentary regime of these estuaries. The gravity cores at the mouth of the Nelson River recorded several cm-thick rapidly deposited layers with a reverse to normal grading sequence, indicating the occurrence of hyperpycnal flows generated by major floods during the last few centuries. These hyperpycnal flows were probably caused by ice-jam formation, which can increase both the flow and the sediment concentration following the breaching of such natural dams. Following the construction of hydroelectric dams since the 1960s, the regulation of river discharge prevented the formation of hyperpycnal flows, and hence the deposition of hyperpycnites in the upper part of the cores. In the core sampled in the estuary of the Churchill River, only one hyperpycnite was recorded. This lower frequency may be due to the enclosed estuary of the Churchill River, its weaker discharge and the more distal location of the coring site.In the Gulf of St. Lawrence, grain size measurements allowed the identification of a major flood around AD 1844±4 years in box cores from both the Sainte-Marguerite and Moisie Rivers, whereas a drastic decrease in variations in the median grain size occurred around AD ~1900 in the estuary of the Sainte-Marguerite River, highlighting the offshore impact of the SM1 dam construction in the early 1900s. Furthermore, sedimentological variations in the box cores from both estuaries have been investigated by wavelet analysis and the sharp disappearance of high frequencies around AD 1900 in the estuary of the dammed river (Sainte-Marguerite River), but not in the estuary of the natural river (Moisie River), also provides evidence of the influence of dams on the sedimentary regime of estuaries.

    Diabetes mellitus is a growing problem in South Africa and of concern to traditional African health practitioners in the Nelson Mandela Metropole, because they experience a high incidence of diabetic cases in their practices. A collaborative research project with these practitioners focused on the screening of Bulbine frutescens, Ornithogalum longibracteatum, Ruta graveolens, Tarchonanthus camphoratus and Tulbaghia violacea for antidiabetic and cytotoxic potential. In vitro glucose utilisation assays with Chang liver cells and C2C12 muscle cells, and growth inhibition assays with Chang liver cells were conducted. The aqueous extracts of Bulbine frutescens (143.5%), Ornithogalum longibracteatum (131.9%) and Tarchonanthus camphoratus (131.5%) showed significant increased glucose utilisation activity in Chang liver cells. The ethanol extracts of Ruta graveolens (136.9%) and Tulbaghia violacea (140.5%) produced the highest increase in glucose utilisation in C2C12 muscle cells. The ethanol extract of Bulbine frutescens produced the most pronounced growth inhibition (33.3%) on Chang liver cells. These findings highlight the potential for the use of traditional remedies in the future for the management of diabetes and it is recommended that combinations of these plants be tested in future.

    Full Text Available In this text, Rudolf Brucci’s opera Gilgamesh is viewed in the light of Ralph Locke’s “All the Music in the Full Context” Paradigm which promotes the approach that one should search for the exotic elements in musical works first in the discursive components (title, program, accompanying notes, visual representations (costume, scenery and a “horizon of expectations” of a particular culture, and only then to observe exoticism as the aspect of a musical style. In the light of this Paradigm, “exoticism” of the opera Gilgamesh is detected at the level of the music material and compositional procedures, but not in the dramaturgical profiling of characters, narrative adaptation of the Sumerian epic, costumes and scenery. The plot, costumes and the scenery of the opera do not construct the Orient with either positive or negative projections attributed to it by the Western European Orientalist discourse, but portray Gilgamesh and Enkidu as ancient mythic protagonists on the margin of the (not-always exoticist once/now binarism. The musical language of the opera, which abounds in the usage of oriental musical scales and citations, indicates that oriental/exotic was one of the author’s “target levels” when conceiving and composing Gilgamesh. Brucci, however, did not build the “ethnological model” in his opera, but gave oriental scales and “exotic” musical citations their meaning within the Western musical tradition, which is why his approach can be compared with the “veiled exoticism” of the French composers of the late nineteenth and the early twentieth centuries. In the light of the self/other binarism, reaching for the exotic in Gilgamesh can be presented as an auto-exotic creative behavior of Brucci as a composer who perceives his “minority identity” in a relation to an imaginary referential system of the Center. However, I am more inclined to see Brucci’s identificational intention in his advocacy of the

The Exhaleair flowstone grew continuously over the last 16 ka, following a 50 ka hiatus in deposition. The speleothems from both caves show similar records of oxygen isotope variation over the last 16 ka. The carbon isotope record from Nettlebed shows considerable variation, of almost 10 per thousand from the last glacial maximum to the early Holocene. It is anticipated that these well-dated speleothem records will enable more accurate constraints to be placed on the timing of glacial advances and vegetation changes in the western South Island than are possible using the available radiocarbon ages alone.

  16. Variation among sub-basins of the upper Nelson River in relationships between precipitation, runoff and the Pacific Decadal Oscillation

    International Nuclear Information System (INIS)

    McCullough, G.

    2008-01-01

    In this paper, I examine relationships between precipitation and river discharge in the Nelson River watershed and several global climate indices. Inter-decadal patterns in discharge and precipitation for several sub-basins closely tracked the Pacific Decadal Oscillation (PDO) through much of the 20th century. The PDO explained 53% of the variability in precipitation and 70% in discharge for the Red River (5-y averages) from 1915-1975. However, since 1975, both precipitation and discharge have increased relative to trend of the PDO. Winnipeg River discharge likewise increased relative to the PDO, but diverged earlier, beginning in 1965. The hydrograph of the Saskatchewan River followed the PDO only until mid-century, after which discharge declined relative to the PDO. The decline of discharge in the Saskatchewan River is not matched by consistent declines in precipitation, but may be partly due to consumptive use, mainly irrigation, and losses due to evaporation from large reservoirs created in the 1960s and 1970s. However, the increases in the Red and Winnipeg River are well-explained by increased spring and summer precipitation. For instance, precipitation was 20-30% higher in the decade 1996-2005 than in the previous decade. By examining historical data, we show the runoff coefficient to increase with increasing discharge, and that the proportional increase is greater in the Red than in the Winnipeg River basin. In the Red, the moderate difference in precipitation was amplified into a doubling of annual mean discharge. Comparing the same 2 periods, a smaller 10% increase in precipitation in the Winnipeg River basin explains a 27% increase in discharge. (author)

    Full Text Available Fictions Inc., and this interview, offers detailed readings of a diverse body of texts that, in one way or another, push readers to think about the role of the corporation in 20th and 21st century America. Using a complex set of critical tools—historicizing the rise in the pharmaceutical industry in the 1980s to read White Noise; drawing on Slavoj Žižek and Louis Althusser to explain the model of resistance that appears in Crying of Lot 49; looking at 1980s gentrification policies and government outsourcing while discussing Ghostbusters—Clare generates a series of insights about the fears and the desires embodied in the corporation. What he finds is that older avenues of resistance to consumer capitalism have closed, but the desire to imagine new ones, and maybe create them, remains open.

    The subject article (Nelson and Mayo 2014) presents an overview of previous reports of interbasin flow in the Great Basin of the western United States. This Comment is presented by authors of a cited study (comprising chapters in one large report) on the Great Basin carbonate and alluvial aquifer system (GBCAAS; Heilweil and Brooks 2011; Masbruch et al. 2011; Sweetkind et al. 2011a, b), who agree that water budget imbalances alone are not enough to accurately quantify interbasin flow; however, it is proposed that statements made in the subject article about the GBCAAS report are inaccurate. The Comment authors appreciate the opportunity to clarify some statements made about the work.

    Full Text Available This article aims to address two thesis presented in the Congress of the Brazilian Film in the  1950s to relate them to the beggining of formation of the Brazilian cinematographic field. More precisely, we will analyze Folclore e Cinema, thesis defended by Solano Trindade in the I Congresso Nacional do Cinema Brasileiro; and O problema do conteúdo no cinema brasileiro, presented by Nelson Pereira dos Santos in the I Congresso Paulista do Cinema Brasileiro. From them, we will analyze which images of Brazilian people these thesis articulated in their defenses. Our hypothesis is that, in order to use Gilberto Freyre’s ideas, these intellectuals chose the image of the Brazilian people as a racially, ethnically and culturally heterogeneous people, but in the process of integration. This is not to say that they only reproduce these ideas, but actively used in shaping the habitus of cinematographic field at that time.

    The HIV prevalence in South Africa among students at higher education institutions (HEIs) in 2008 was reported to be 3.4%, with the highest HIV prevalence found in the Eastern Cape Province. Students at these facilities are also increasingly affected by socio-economic constraints that may impact on food security. Little is known about the impact of food insecurity on HIV-infected students in HEIs in South Africa. The purpose of this paper is to describe food insecurity and the nutritional status among HIV-infected students on the Nelson Mandela Metropolitan University campuses in South Africa, as well as current initiatives to strengthen the safety nets for food-insecure students. This descriptive, cross-sectional survey was conducted among a convenience sample of known HIV-infected, registered students (n = 63), older than 18 years of age and managed as part of the Campus Health Service antiretroviral therapy (ART) programme. Ethical approval for the study was obtained from the Research Ethics Committee (NMMU) and participants were included in the sample after providing written, informed consent. Findings indicate that food insecurity was common with more than 60% of the sample reporting food insecurity at the household level during the previous month. Of the sample, 51% were classified as being either overweight or obese. Although food insecurity did not contribute to weight loss in our sample, food-insecure students were more likely to consume inadequate amounts of vitamins and minerals, especially antioxidants that are important in supporting the immune system. Food insecurity has been identified as affecting the majority of HIV-infected students in this study, especially regarding their difficulty in accessing nutritious foods. As overweight and obesity also seem to threaten the health and future well-being of the students, appropriate management of the overweight individuals and those with obesity should be instituted in order to prevent the development

    The Arapahoe snowfly, Arsapnia arapahoe (Nelson & Kondratieff, 1988) (Plecoptera: Capniidae) is a candidate species warranted for listing under the Endangered Species Act. Prior to this study, A. arapahoe was known from only two tributaries of the Cache la Poudre River in Larimer County, Colorado: Young Gulch and Elkhorn Creek. The objectives of this study were to determine the distribution of this endemic stonefly, and to identify sympatric species as possible surrogate indicators of its occurrence. Eighty-four streams were sampled within the expected geographical range and emergence time-period from 2013 to 2017. Adults of A. arapahoe were discovered in 19 first-, second-, and fourth-order streams beyond the original type localities tributary to the Cache la Poudre River. The new and recently recorded localities were discovered in the Big Thompson River, St. Vrain River, Boulder Creek, and Upper South Platte River Watersheds. Two species, A. decepta (Banks, 1897) and Capnia gracilaria Claassen, 1924, always co-occurred with A. arapahoe, suggesting this species pair may serve as a surrogate indicator of suitable stream habitat for A. arapahoe. Suggestions for future investigation into the distribution, life-history, and habitat of A. arapahoe are presented to aid the conservation of this rare and endemic Colorado stonefly.

    Intracranial suppuration (ICS) is a life-threatening condition caused by various disease processes and consisting of brain abscess and extradural and subdural empyema. The major causes have changed over the decades. To the author's knowledge, the incidence of ICS in South Africa (SA) has not been established. To determine the incidence of ICS, overall and according to age and gender, and to identify the source and distribution of ICS. The archive of the radiology departments at Umtata General Hospital and Nelson Mandela Academic Hospital in the Transkei region, Eastern Cape Province, SA, was searched retrospectively for computed tomography (CT) reports of patients diagnosed with ICS. Cases in which the CT images, patients' clinical information and CT reports were available for an uninterrupted period of at least 1 year were included. Five time frames were established, encompassing 8 years of data. The first time frame established an incidence of ICS of 1/100,000/year for the Transkei region. All the time frames were utilised to determine the incidence according to gender and age, and the source and distribution of ICS. The incidence of ICS was higher among males than females, and highest in the age groups 0-10 and 11-20 years. A seasonal variation in the incidence of sinusitis- and meningitis-related ICS was noted. Numbers of cases declined during the last 3 years of the study period. Sinusitis, head trauma, ear infection and meningitis were the major sources of ICS. A pulmonary source was not a major feature. In the last 4 years, trauma became the commonest source of ICS. A steady decline in ear infection- and meningitis-related ICS was noted.

    Abstract Background Trends in career choice amongst medical graduates have considerable implications for the percentage of the workforce available for training. Objective To investigate and review factors affecting career choice by undergraduate first-year medical students. Method This was a cross-sectional study using a closed-ended, semi-structured survey instrument. Two hundred and four questionnaires were administered to all first-year medical students at the Nelson R. Mandela School of Medicine in the first term of the 2012 academic session. Results The questionnaire was completed by 167 out of 204 students (81.8% response rate). Most of the respondents were South Africans (91%) and blacks (72%), with a higher proportion of women to men (2:1). The majority (86%) intended to undertake their postgraduate training in surgical specialties (53%), general surgery (50%) and cardiology (46%). Few were interested in an academic career in basic sciences (27.6%), either because they were not interested in research and/or teaching (48%), not clinically-orientated (20%), or found it to be an unattractive choice (12.3%). The top perceived career-related factors favouring choice of speciality were personal interest and benefits to patients as many (83%) respondents still viewed the medical profession as having a bright future in South Africa. Conclusions Our study highlighted the fact that self and patient interests were strong determinants of speciality choices by the students and the role of parents and practice in rural areas were considered least as potential influencing factors. This would appear to be a good indicator that the healthcare sector may be boosted in the future by doctors who are wholeheartedly committed to the service of the communities with the greatest disease burden.

    Full Text Available Mandela’s victory in the 1994 elections in South Africa is a reference point for South African history and represented the transition from apartheid to multiracial democracy. Since then Nelson Mandela (1994-1999, Thabo Mbeki (1999-2008 and Jacob Zuma (2009 - current, occupied the post of president of the country and led, each in its own way, the new direction of the country. During the nearly twenty years of multiracial democracy, one in particular cartoonist, Jonathan Shapiro, popularly known by the pseudonym Zapiro, portrayed the everyday life of this story. In this sense, the objective of this research is to analyze how Zapiro portrayed the political and social aspects, as well as the psychological characteristics of each of the three postapartheid presidents and which social representations are formed from their cartoon production. The choice of Zapiro explained by openly declared his opposition to apartheid and also for being the best known outside South African cartoonist. We elected to cartoon as an object of study because it is an iconographic object constituted by communicative humor, which adds to its constitution arguments transgression of the established order, enabling an analysis of South African history through a critical bias. As methods for the development of the work, we decided to gather historical research, the literature search and analysis of cartooon speech. Among the theoretical frameworks stand out Magnoli (1998, 2009, Jonge (1991 and Carlin (2009 in the South African question; reflections about social representations, we resort to Moscovici (2011 and Jodelet (1993, in the field the cartoon and humor, the references are Miani (2005; 2012, Romualdo (2000 and Eco (1989. With the completion of the analysis, we observed that Zapiro acts in different ways in the construction of the representation of each of the presidents in question and that the cartoonist presents Mandela as a competent leader marked by heroism and

    Full Text Available Uma pesquisa Intensiva com os usuários finais no setor da Habitação Econômica da República Sul-Africana tornou-se necessário para encontrar formas de enfrentar o contínuo aumento dos custos e ainda continuar a satisfazer as preferências, com qualidade e acessibilidade. A pesquisa tem de ser sucedida por projetos inovadores e métodos construtivos rápidos e de baixo custo, sem perder qualidade e estética. Os custos de terreno e o adensamento dos projetos, em equilíbrio com a qualidade ambiental, tornaram-se de enorme importância em qualquer empreendimento sustentável. O mesmo se aplica às vizinhanças, quanto à revitalização dos bairros. Um exemplo típico é o Nelson Mandela Bay Metropole na África do Sul, onde 100.000 unidades habitacionais precisam ser construídas em um período de três a cinco anos para acabar com o déficit. A quantidade de dados relativos a uma única habitação é vasta e, em um grande empreendimento, ainda mais significativa. Tradicionalmente, os dados são armazenados em vários locais, por exemplo, com autoridades governamentais, arquitetos ou outros profissionais, empreendedores, subcontratados, agentes imobiliários, instituições financeiras ou proprietários. Baixa eficiência e atrasos substanciais são o resultado, quando os dados existentes não podem ser acessados rapidamente, ou não são encontrados. Um processo de localização espacial e sistema de controle de dados física e inequivocamente associado com cada particular unidade habitacional foi desenvolvido para resolver com sucesso a maioria desses problemas.

    The Nobel Prize in Physiology or Medecine 2011 was awarded to Ralph M. Steinman, Jules A. Hoffman and Bruce A. Beutler for the discovery of essential elements of innate immunity, in particular dendritic cells (DCs) and toll-like receptors (TLRs). Antigens become immunogenic and capable of triggering an adaptive immune response involving antigen-specific, MHC- restricted effector T cells, only if they are captured and presented by “accessory” cells. In 1972, Ralph M. Steinman and Zanvil Cohn identified in lymphoid tissues, cells with treelike, arborescent morphology that they named “dendritic cells” (DC) (from the greek word “tree” for tree, δένδρον) with a superior ability to induce alloreactive T cell proliferation in vitro (1978) and to stimulate the rejection of kidney allotransplants in rodents (1982). Thirty years after their discovery, DCare now known to play a seminal role in bridging innate and adaptive immunity, In addition DC are being used in numerous clinical studies all over the world to increase immunity to infectious or tumor-associated antigens. This effort involved the contribution of an international network of basicand clinical scientists spearheaded by Ralph M. Steinman to defineappropriate culture conditions to generate ex vivo DC from circulating or bone marrow precursors, to definefunctionally distinct DC subsets, to identifytheir maturation pathways including those relying on the stimulation of TLRs, and finally to develop DC based-vaccines to immunize patients infected with HIV or affected by cancer. Here, we will detail the history of DC and outline the therapeutic implications of Ralph M. Steinman’s seminal discovery.

    Los mayores costos de producción del clavel estándar se asocian con la mano de obra que se utiliza en las labores del cultivo; el desbotone es una de las actividades que demanda mayor uso de mano de obra y tiempo. El objetivo del estudio fue determinar el efecto del desbotone en diferentes estadios de desarrollo del botón principal, sobre la producción y calidad en poscosecha del clavel estándar variedad Nelson en el primer pico de cosecha. Se evaluaron los estadios conocidos popularmente como botón ‘arveja’, ‘garbanzo’, ‘barril’, ‘estrella’, ‘bala’ y ‘punto de corte’. Las variables medidas incluyeron producción total a primera cosecha, grados de calidad y algunos criterios de clasificación en poscosecha. Se concluyó que el desbotone en los estadios evaluados no influye significativamente en la producción total del clavel en la primera cosecha. Sin embargo, en la clasificación por grados de calidad, se encontraron diferencias significativas: el desbotone en botón arveja’, ‘garbanzo’ y ‘barril’ mostró mayores promedios en el número de tallos grado ‘select’, mientras que el desbotone en botón ‘estrella’, ‘bala’ y ‘punto de corte’ reflejó mayores promedios para los grados ‘fancy’ estándar y nacional. El desbotone en diferentes estadios de desarrollo del botón principal afectó el número de tallos torcidos, sin aumentar significativamente el número de tallos débiles. El ensayo permitió definir que la etapa crítica para el desbotone son los estadios de desarrollo del botón principal previos al estadio ‘barril’, pues pasado este punto disminuye la calidad del producto.

  6. LETTERS AND COMMENTS: Comment on 'Reinterpreting the famous train/embankment experiment of relativity'

    Science.gov (United States)

    Rowland, David R.

    2004-09-01

    Nelson (2003 Eur. J. Phys. 24 379) recently claimed on logical grounds that Einstein's train and embankment thought experiment cannot be used to prove the relativity of simultaneity prior to knowledge of the Lorentz transformations as it is purported to do. It is argued in this comment that Nelson's claim is based on premises which are incorrect, thus invalidating his conclusions. It is also argued that Nelson's article furnishes a 'proof by contradiction' of the desired result, thus also invalidating his claim.

  10. Stochastic mechanics of mixed states

    International Nuclear Information System (INIS)

    Jaekel, M.T.; Pignon, D.

    1984-01-01

    Nelson's stochastic interpretation of quantum mechanics is extended from the case of pure states to that of mixed states. It is shown that a pure probabilistic formalism, which applies the Newton-Nelson Law to the initial position and velocity distributions, does not reproduce the time evolution predicted by quantum mechanics. In order to recover the latter, a new notion must be introduced, that of pure quantum states, over which the mixture has to be decomposed, and which then satisfy the Newton-Nelson Law independently.

    Merges and Nelson have provided an empirically grounded argument that firms use pioneer patents of 'broad' scope to block downstream technological development (Merges and Nelson 1990). If this is a regular occurrence then, as they claim, they have faulted Kitch's 'prospect theory' of patents (Kitch...... 1977), a theory that is a version of the classic justification for the award of the exclusive right - that it should protect the incentive to develop property. Merges and Nelson insist that their thesis should be supported by empirical evidence and they turn to historical accounts as an important form...

The intense, rainbow-colored Mandela portrait that opens this issue is the work of a young Indonesian digital artist, Ihsanulhakim, who captures a serious, reflective and aged version of the South African leader. The writing on the top left of the image is a quote from Mandela’s famous reflection on death translated into Indonesian: “Death is something inevitable. When a man has done what he considers to be his duty to his people and his country, he can rest in peace”.[1] [1] RIP Nelson Mandela © Muhammad Ihsanulhakim. I wish to thank the artist for generously allowing Altre Modernità to reproduce his work.

  3. Homosexual Identity in Alex Sanchez's 'Rainbow Trilogy'

    Directory of Open Access Journals (Sweden)

    Full Text Available This research aims at describing 1 stages of homosexual identity development in three main characters in the Rainbow Trilogy using Cass model, 2 factors influencing the development of homosexual identity using D Augellis theory, and 3 forms of victimization towards homosexuals experienced by the main characters using theories of D Augelli and Rivers. Queer studies was applied to describe and analyze the data in forms of words, phrases, sentences, statements, dialogues as well as monologues in the Rainbow Trilogy, recording thoughts and actions by the characters in accordance with the research focus. As a result, the research finds out that the three novels describe clearly all stages of Cass model of homosexual identity development in Jason and Kyle, including their identity confusions, comparisons, acceptances, tolerances, prides and syntheses. In Nelson, only one stage that can be identified as Nelson is described as one whose sexual identity has been formed. The research also reveals how factors of personal subjectivity and action, interactive intimacy and sociohistorical connection are connected to each others and also influencing the homosexual identity developments of the main characters. Besides, the research also shows that various kinds of victimization occur to Jason, Kyle and Nelson. Normative victimizations made to feel different are experienced by Nelson and Kyle. Family stressor and prejudices in connection to AIDS are experienced by the three characters. Victimization of direct attacks in forms of verbal and physical abuses are experienced by Kyle and Nelson. Lastly, the research finds out that Nelson is the only character experiencing sexual abuse. It occurs in form of undesired comments oriented to a sexual violence.

The class of Markov fields so characterized has a as a cubclass the class of Markov fields which lead by Nelson's Reconstruction Theorem to some covariant (free) quantum fields. (orig.)

  14. Figural properties are prioritized for search under conditions of uncertainty: Setting boundary conditions on claims that figures automatically attract attention.

    Science.gov (United States)

    Peterson, Mary A; Mojica, Andrew J; Salvagio, Elizabeth; Kimchi, Ruth

    2017-01-01

    Nelson and Palmer (2007) concluded that figures/figural properties automatically attract attention, after they found that participants were faster to detect/discriminate targets appearing where a portion of a familiar object was suggested in an otherwise ambiguous display. We investigated whether these effects are truly automatic and whether they generalize to another figural property-convexity. We found that Nelson and Palmer's results do generalize to convexity, but only when participants are uncertain regarding when and where the target will appear. Dependence on uncertainty regarding target location/timing was also observed for familiarity. Thus, although we could replicate and extend Nelson and Palmer's results, our experiments showed that figures do not automatically draw attention. In addition, our research went beyond Nelson and Palmer's, in that we were able to separate figural properties from perceived figures. Because figural properties are regularities that predict where objects lie in the visual field, our results join other evidence that regularities in the environment can attract attention. More generally, our results are consistent with Bayesian theories in which priors are given more weight under conditions of uncertainty.

  15. Revising the Complex Economics of Patent Scope

    DEFF Research Database (Denmark)

    Howells, John

    Merges and Nelson claim to have provided an empirically grounded argument that pioneer patents of 'broad' scope are used to block technological development. It is widely understood in both law and economics that they have, as they claim, faulted Kitch's 'prospect theory' of patents, a theory...... that a function of patents is to enable the coordinated development of novel technical ideas. This article is a critical review of Merges and Nelson's historical empirical evidence. I find that, first, 'broad' scope is only implicated in one of the examples cited by Merges and Nelson as supportive evidence...... - the Wright brothers' warped-wing patent; second, that strict development block, defined as the prevention, or retardation of the development of technology understood to be capable of useful development, was not illustrated by any of their examples. Therefore I conclude that their general thesis...

    1987-01-01

    We found small amounts of cholecystokinin in the normal human adenohypophysis and therefore examined pituitary tumors from 87 patients with acromegaly, Cushing's disease, Nelson's syndrome, prolactinoma, or inactive pituitary adenomas. Five adenomas associated with Nelson's syndrome contained......'s disease and 7 acromegaly with adenomas containing ACTH. The cholecystokinin peptides from the tumors were smaller and less sulfated than cholecystokinin from normal pituitary glands. We conclude that ACTH-producing pituitary cells may also produce an altered form of cholecystokinin....

    1982-01-01

    Comparative analysis of methods for determination of microgram amounts of 14 C-labelled sugars has been carried out. The ferricyanide and Shomodyi-Nelson methods were approbated in experimental study. The relative error of the ferricyanide method was found to be smaller than that of the Shomodyi-Nelson method. Thus the ferricyanide method was used for obtaining calibration curves for 15 sugars. The accuracy for sugar amounts higher than 3 μg/10 ml was better than +, - 5% [ru

    Qiu, S.; Amano, H.; Kasai, A.

    1988-01-01

    The solid angle in extended alpha source measurement for a series of counting geometries has been obtained by two methods: (1) calculated by means of the Nelson Blachmen series; (2) interpolated from the data table given by Gardner. A particular consequence of the application of the Nelson Blachmen series was deduced which was different from that given by the original author. The applicability of these two methods, as well as an experimentally measured method, is also evaluated. (author)

    1979-01-01

    We show that there exists a unitary map connecting linearized theories of gravitational potential in vacuum, formulated in various covariant gauges and noncovariant radiation gauge. The free Euclidean gravitational potentials in covariant gauges satisfy the Markov property of Nelson, but are nonreflexive. For the noncovariant radiation gauge, the corresponding Euclidean field is reflexive but it only satisfies the Markov property with respect to special half spaces. The Feynman--Kac--Nelson formula is established for the Euclidean gravitational potential in radiation gauge

    Diffusive motion--displacement due to the cumulative effect of irregular fluctuations--has been a fundamental concept in mathematics and physics since Einstein''s work on Brownian motion. It is also relevant to understanding various aspects of quantum theory. This book explains diffusive motion and its relation to both nonrelativistic quantum theory and quantum field theory. It shows how diffusive motion concepts lead to a radical reexamination of the structure of mathematical analysis. The book''s inspiration is Princeton University mathematics professor Edward Nelson''s influential work in

    Vectorcardiograms were obtained from 50 young domestic pigs using the Nelson lead system. Compensation for body size and shape is achieved and the resultant dipole moment magnitude reflects heart size. A strong relationship was found between heart size and maximum magnitude. Dipole moment magnitude increased as four pigs increased from five to ten weeks of age. The dipole moment during QRS is considered in light of known pig heart excitation pattern. Dipole locations during QRS, calculated by computer solution of the Gabor-Nelson equations, were in agreement with heart location and excitation data.

  7. Complexity index indicates refinery capability, value

    International Nuclear Information System (INIS)

    Johnston, D.

    1996-01-01

    Refinery size usually is measured in terms of distillation capacity. Relative size, however, can be measured using refinery complexity--a concept developed by W.L. Nelson in the 1960s. Nelson developed the complexity index to quantify the relative cost of components that make up a refinery. It is a pure cost index that provides a relative measure of the construction costs of a particular refinery based on its crude and upgrading capacity. The Nelson index compares the costs of various upgrading units--such as a fluid catalytic cracking (FCC) unit or a catalytic reformer--to the cost of a crude distillation unit. Computation of the index is an attempt to quantify the relative cost of a refinery based on the added cost of various upgrading units and the relative upgrading capacity. A review of complexity calculations, and an explanation of how indices have changed, provide a simple means of determining the complexity of single refineries or refining regions. The impact of complexity on product slate is also examined in this paper

  17. Allocation - the Howe measurement challenges

    Energy Technology Data Exchange (ETDEWEB)

    Tierney, Jim; Moksnes, Paul Ove

    2005-07-01

    The Howe Field is located in the Central North Sea Block 22/12a approximately 160 km east of Aberdeen in a water depth of 85 m. The reservoir lies some 12 km east of the Shell operated Nelson Platform, which is situated in adjacent Block 22/11. The Howe project was initiated by Shell Exploration and Production to augment the operating life and production capacity of the Nelson platform, involving the development of an additional subset infrastructure and the installation of topside facilities. The owners of the Howe Field are Enterprise Oil PLC , Intrepid Energy and OMV. The Howe well fluids are commingled with Nelson fluids. Therefore, it is required to measure the Howe well fluids to differentiate between the fields and to determine how much money each partner is allocated. The commercial agreements have stipulated that the measurements of Howe fluids are required to be measured within an accuracy of +- 5% of reading. In addition to accuracy constraints, it was important to minimise capex to ensure the development was economically viable. Given this, multiphase metering was considered to be a solution for allocation between the different ownerships, as opposed to traditional separator metering. This paper will present the journey of the project activity through the selection criteria, flow loop test, installation, commissioning and the first 3 months of operation of the MPFM including verification with the Nelson test separator. Detailing with careful management and engineering support how to succeed with this type of application. (author) (tk)

  18. Zero-Headspace Coal-Core Gas Desorption Canister, Revised Desorption Data Analysis Spreadsheets and a Dry Canister Heating System

    Science.gov (United States)

    Barker, Charles E.; Dallegge, Todd A.

    2005-01-01

    Coal desorption techniques typically use the U.S. Bureau of Mines (USBM) canister-desorption method as described by Diamond and Levine (1981), Close and Erwin (1989), Ryan and Dawson (1993), McLennan and others (1994), Mavor and Nelson (1997) and Diamond and Schatzel (1998). However, the coal desorption canister designs historically used with this method have an inherent flaw that allows a significant gas-filled headspace bubble to remain in the canister that later has to be compensated for by correcting the measured desorbed gas volume with a mathematical headspace volume correction (McLennan and others, 1994; Mavor and Nelson, 1997).

  10. Coal reburning technology for cyclone boilers

    International Nuclear Information System (INIS)

    Yagiela, A.S.; Maringo, G.J.; Newell, R.J.; Farzan, H.

    1990-01-01

    Babcock and Wilcox has obtained encouraging results from engineering feasibility and pilot-scale proof-of-concept studies of coal reburning for cyclone boiler NO x control. Accordingly, B and W completed negotiations for a clean coal cooperative agreement with the Department of Energy to demonstrate coal reburning technology for cyclone boilers. The host site for the demonstration is the Wisconsin Power and Light (WP and L) Company's 100MWe Nelson Dewey Station. Reburning involves the injection of a supplemental fuel (natural gas, oil, or coal) into the main furnace to produce locally reducing stoichiometric conditions which convert the NO x produced therein to molecular nitrogen, thereby reducing overall NO x emissions. There are currently no commercially-demonstrated combustion modification techniques for cyclone boilers which reduce NO x emissions. The emerging reburning technology offers cyclone boiler operators a promising alternative to expensive flue gas cleanup techniques for NO x emission reduction. This paper reviews baseline testing results at the Nelson Dewey Station and pilot-scale results simulating Nelson Dewey operation using pulverized coal (PC) as the reburning fuel. Outcomes of the model studies as well as the full-scale demonstration preliminary design are discussed

    2006-01-01

    The collection of all the rough sets of an approximation space has been given several algebraic interpretations, including Stone algebras, regular double Stone algebras, semi-simple Nelson algebras, pre-rough algebras and 3-valued Lukasiewicz algebras. A 3-valued Lukasiewicz algebra is a Stone algebra, a regular double Stone algebra, a semi-simple Nelson algebra, a pre-rough algebra. Thus, we call the algebra constructed by the collection of rough sets of an approximation space a rough 3-valued Lukasiewicz algebra. In this paper,the rough 3-valued Lukasiewicz algebras, which are a special kind of 3-valued Lukasiewicz algebras, are studied. Whether the rough 3-valued Lukasiewicz algebra is a axled 3-valued Lukasiewicz algebra is examined.

Johnson VA Medical Centre, Charleston, SC, USA; 3Department of Psychiatry and Behavioral Sciences, Medical University of South Carolina, Charleston, SC, USA; 4Neurology Service, Ralph H. Johnson VA Medical Centre, Charleston, SC, USA Abstract: Individuals with Parkinson’s disease (PD exhibit higher rates of depression and anxiety than the general and other medically disabled populations. Evidence suggests that mood and anxiety symptoms are related to disease pathology. Rates of depression and anxiety in PD vary depending on how these symptoms are measured, but they are estimated to occur in up to 40% of patients. These conditions have adverse effects on patient and caregivers’ quality of life, level of disability, and mortality, with several studies suggesting greater contribution than motor symptom severity. Pharmacological and psychotherapeutic interventions, particularly in combination, have demonstrated efficacy in treating depression and anxiety in PD. However, additional randomized controlled trials are needed to better delineate when and how to best treat these disabling symptoms.

    2018-01-01

    Bi-directional reflectance measurements of analogs for planetary regolith have provided insight into the surface properties of planetary satellites and small bodies. Because Aluminum Oxide (Al2O3) and water ice share a similar hexagonal crystalline structure, the former has been used in laboratory experiments to simulate the regolith of both icy and dusty planetary bodies. By measuring various sizes of well sorted size fractions of Al2O3, the reflectance phase curve and porosity of a planetary regolith can be determined. We have designed an experiment to test the laboratory measurements produced by Nelson et al. (2000). Additionally, we made reflectance measurements for other alkali-halide compounds that could be used for applications beyond astronomy and planetary science.In order to provide an independent check on the Nelson et al. data, we designed an instrument with a different configuration. While both instruments take bidirectional reflectance measurements, our instrument, the Rigid Photometric Goniometer (RPG), is fixed at a phase angle of 5° and detects the scattered light with a photomultiplier tube (PMT). The PMT current is then measured with an electrometer. Following the example of Nelson et al., we measured the bidirectional reflectance of Al2O3 particulate size fractions between 0.1sizes from 20size that provided optimal, or maximum, reflectance for each compound. Our conclusions bring confirmation and clarity to photometric sciences.

  1. Red Mandela: Contests of auto-biography and Auto/biography in South Africa

    Directory of Open Access Journals (Sweden)

    Ciraj Rassool

    Full Text Available This article examines the case of the red Mercedes-Benz built in 1990 by workers at the Mercedes-Benz plant in East London and presented to Nelson Mandela as a gift shortly after his release from prison. During the 1990s a biographic order marked by a discourse of heroic leaders was growing in South Africa, where biographic narration and self-narration played a noticeable and, at times, substantial part in political transformation and reconstruction. Nelson Mandela's 'long walk to freedom' became the key trope for South Africa's history, narrated as the triumph of reconciliation. The presentation of the car to Nelson Mandela in 1990 occurred at a time of transition in the life of his auto/biography, from the biography of desire for the absent revolutionary leader to the biography of a statesman and president. This partly explains the ambiguous, double-edged history of the gift, as a labour of love on the part of NUMSA workers and as donation by Mercedes-Benz South Africa (the corporate version of these events emphasised the 'friendship' that was 'sparked' between Nelson Mandela and Mercedes-Benz South Africa. Inspired by the East London autoworkers' commitment to produce the car for Mandela, as well as by the resilience some of them showed during their nine-week strike and sleep-in in the plant soon afterwards, Simon Gush's installation Red has intervened in how those events should be remembered. By choosing to exhibit the disassembled body panels of a replica car alongside reconstructed displays of sleep-in strike beds made of scaffolding, foam, upholstery and car headrests, with imagined uniforms of striking workers, Gush has chosen to appropriate the history of the events of 1990 from the celebratory frames of the Mandela biographic order. The installation turns into an inquiry into the labour process and the events of the strike that was critical of the reconciliatory and celebratory understanding of the gift as a product of a partnership

  10. Analysis of the thermal fragmentation as a mechanism for the initiation of steam explosion

    International Nuclear Information System (INIS)

    Lamome, J.; Meignen, R.

    2007-01-01

    We propose a theoretical study of the film behaviour and its stability during the phenomenon of drop thermal fragmentation. We discuss the role of the various possible influences on the film collapse and instability processes. First, we discuss the possibility of simple fuel/coolant contacts as a mechanism for the drop instability. Under this assumption, we then describe and test our model on Nelson and Duda explodability maps, with a particular emphasis on the description of the film evolution. The reasonable agreement obtained allows us to analyse the effect of various parameters as the ambient pressure, subcooling and trigger pulse shape on the film behaviour in Nelson and Duda experiments. The perspectives of this work are then shortly discussed including extrapolation to more prototypic situations and the role of thermal fragmentation itself. (authors)

    The defining principle and examples of β eff measurement method: the substitutional method, Cf neutron source method, Bennett method, the coupling coefficient method and Nelson method were introduced and surveyed. Measurement errors and C/E value of the substitutional, Cf ray source and Bennett method were of the order of 3%, 5% and 3 - 6% and 0.903 - 0.965, 1.85 and 1.019 - 1.165, respectably. Evaluation of the absolute value is so hard that β eff measurement belongs to the difficult experiment. The dependence on nuclear calculation in decreasing order is the substitutional, Cf ray source, Bennett, the coupling coefficient and Nelson number method. If good substitute materials were selected, the substitutional method has possibility to determine β eff by small correction value or independent on calculation. (S.Y.)

  5. Distribution Characteristics of Eggs and Neonate Larvae of Codling Moth, Cydia pomonella (L.) (Lepidoptera: Tortricidae)

    Science.gov (United States)

    Wearing, Christopher H.

    2016-01-01

    Literature is reviewed on the spatial distribution of the eggs and neonate larvae of codling moth on apple trees in relation to research conducted in Nelson, New Zealand. At Nelson, oviposition increased with height and was greater in the north and east of the trees and in those with greater fruit load in some seasons, which matches published reports. All publications and the research recorded high percentages of eggs laid singly within 10–15 cm of the fruit, with most eggs on leaves even within fruit clusters; oviposition on fruit clusters of different sizes was nonrandom because more eggs were laid on those with more fruit, but the aggregation of both per cluster and within clusters was even greater than that caused by the fruit number alone. Oviposition at random with respect to the fruit occurred only at very low population density. The choice of oviposition site between fruit and the adaxial leaf surface and abaxial leaf surface (AbLS) was variable and cultivar related. Cultivars on which eggs predominated on the AbLS were less frequent and characterized by low trichome density. In the literature, neonate larvae from eggs on the AbLS suffered greater mortality, as did those in Nelson that hatched more distant from the fruit. This review discusses the interaction between these distribution characteristics and species-specific host–plant volatiles, egg adhesion to plant surfaces, oviposition deterrents, predation, and their relevance to pest management.

  6. A colorimetric method to quantify endo-polygalacturonase activity.

    Science.gov (United States)

    Torres, Sebastián; Sayago, Jorge E; Ordoñez, Roxana M; Isla, María Inés

    2011-02-08

    We report a new colorimetric assay to quantify endo-polygalacturonase activity, which hydrolyzes polygalacturonic acid to produce smaller chains of galacturonate. Some of the reported polygalacturonase assays measure the activity by detecting the appearance of reducing ends such as the Somogyi-Nelson method. As a result of being general towards reducing groups, the Somogyi-Nelson method is not appropriate when studying polygalacturonase and polygalacturonase inhibitors in plant crude extracts, which often have a strong reducing power. Ruthenium Red is an inorganic dye that binds polygalacturonic acid and causes its precipitation. In the presence of polygalacturonase, polygalacturonic acid is hydrolyzed bringing about a corresponding gain in soluble Ruthenium Red. The described assay utilizes Ruthenium Red as the detection reagent which has been used previously in plate-based assays but not in liquid medium reactions. The new method measures the disappearance of the substrate polygalacturonic acid and is compared to the Somogyi-Nelson assay. The experimental results using lemon peel, a fern fronds and castor leaf crude extracts demonstrate that the new method provides a way to the quickly screening of polygalacturonase activity and polygalacturonase inhibitors in plant crude extracts containing high amounts of reducing power. On the other hand, the Ruthenium Red assay is not able to determine the activity of an exo-polygalacturonase as initial velocity and thus would allow the differentiation between endo- and exo-polygalacturonase activities.

The information is then entered onto computer manually, thus making the process a long and arduous one. With the development of the Haiti Commodity Tracker mobile app, we are able to make this commodity price data recording process more efficient. Officials may use this information for making inferences about the difference in commodity prices and for food distribution during critical time after natural disasters. This information can also be utilized by governments and aid agencies on their food assistance programs. Agronomists record the item prices from several sample sites in a marketplace and compare those results from other markets across the region. Due to limited connectivity in rural areas, data is first saved to the phone's database and then retransmitted to a central server via SMS messaging. The mobile app is currently being field tested by an international NGO providing agricultural aid and support in rural Haiti.

    In support of a hydrogeologic study of the groundwater resources on Fort Irwin, we have combined new gravity data with preexisting measurements to produce an isostatic residual gravity map, which we then separated into two components reflecting (1) the density distribution in the pre-Cenozoic basement complex and (2) the distribution of low-density Cenozoic volcanic and sedimentary deposits that lie on top of the basement complex. The second component was inverted to estimate the three-dimensional distribution of Cenozoic deposits by using constraints from geology, drillholes, and time-domain electromagnetic soundings. In most of the base, the Cenozoic deposits are no more than 300 m thick, except in the basins with more than 500 m of fill beneath Coyote Lake, Red Pass Lake, west of Nelson Lake, west of Superior Lake, Bicycle Lake, and in the vicinity of Nelson Lake.
