Until recently, the technique of laser micro sintering was employed preferentially for the realization of structural features ranging down to 30µm from sub-micrometer grained powders. Lately, however, it has been increasingly applied to process coarser powders with grain sizes in the dimension of 10µm. Although a reduction of the resolution has to be taken into account - minimal structures are around 60µm ‐ the variety of available feedstock is considerably higher, allowing for the choice of more economic and industrially interesting materials. Additional advantages are: accelerated performance and improved solidity of the products. Sinter results with a nickel-chromium alloy and a stainless steel powder are presented.


Abstract: Parkinson's disease is one of the most commonly occurring neurodegenerative disorders, ranking 2nd after Alzheimer's affecting largely senior people and characterized by significant nerve cell degeneration that limits motion and daily activities. While the usual age of onset is 60 years, persons as young as 18 years old have been diagnosed. Unintentional shaking and tremors in the hand may be the patient's initial symptoms, making it hard for them to do ordinary actions such as eating food from a spoon. The goal of this project is to produce a stabilising spoon for Parkinson's disease patients so they can eat comfortably despite suffering tremors since it compensates for the user's movement. This project intends to create a less expensive solution to the Liftware and Gyenno "smart" spoons, hence boosting our device's availability and usability. As a result, the major goal of this project is to provide a more accessible and less expensive alternative to the existing "smart" spoons in the industry, which is just as effective and hence beneficial to society


In 1985 the National Aeronautics and Space Administration (NASA) and the University of Alaska agreed to implement, at the Geophysical Institute of the Fairbanks campus, a facility dedicated to the acquisition, processing, distribution, and archival of synthetic aperture radar (SAR) data to be downlinked from satellites. Since then, the Alaska SAR Facility (ASF) has been an active part of NASA's Mission to Planet Earth. ASF Program goals were outlined by Carsey et al. [1987].

Plans were put in place to support three satellites, and the first two, the First European Remote Sensing Satellite (ERS 1) (launched in My 1991) and the Japanese Earth Resources Satellite (JERS 1) (launched in February 1992) are presently in orbit and are being supported by ASF. The third, the Canadian RADARSAT, is scheduled for launch in the spring of 1995. Future satellite missions by U.S. or foreign agencies may well be added in time.


Sinonasal neoplasms were traditionally treated by open approaches. In the past decade, endoscopic approaches have become more widely utilised and are proving to be as effective if not superior in tumour control. Benign sinonasal tumours encompass a collection of pathologies including fibroosseous lesions and neoplastic masses. Malignant tumours are relatively rare and account for only 1 % of all malignancies. The annual incidence for malignant sinonasal tumours is about 0 . 5 – 1 new case per 100 , 000 inhabitants. This is said to be higher in areas such as Asia and Africa where the incidence is between 2 . 5 and 2 . 6 per 100 , 000 per annum in Japan. Sinonasal malignancies are more common in males with a male to female ratio reported to be about 2 : 1 . The most common sinonasal malignancy are the primary endothelial tumours followed by the non epithelial malignant tumours.


ABSTRACT:Over fifty years since its publication, the critical consensus appears to understand When She Was Good (1967) as a curiosity in Roth's oeuvre. It is time for a reappraisal. This article reads the novel in relation to Roth's discussion of what he calls "politicization" in "the Vietnam years," and attempts to rehabilitate the novel and its central character, Lucy Nelson. It argues that the novel is concerned with exploring the gaps between what people say and what they mean, as this pertains to both describing and shaping American reality—an exploration which has implications for understanding the novel's narrative voice.


Vibrio vulnificus is an opportunistic pathogen that causes serious wound infection and fulminant septicemia with a high mortality rate in humans. On entering the host from ocean, V. vulnificus must sense the microenvironments and respond by altering gene expression patterns via alternative sigma factors, such as RpoS and RpoN, to establish a successful infection in humans. To elucidate the virulence mechanism of V. vulnificus YJ016, rpoS and rpoN deletion mutants (YJΔS and YJΔN) and the double mutant (YJΔNS) were initially constructed with allelic exchange technique. Compared to their parental strain YJ016, these mutants had no detectable defect in in-vitro growth; however, the caseinase and hemolytic activities as well as the sucrose fermentation on TCBS were found to be lost in YJΔS. Intriguingly, YJΔS displayed significantly different motility with an increased velocity of swimming on the 0.325 % agar and a radial swarming pattern on solid surfaces. Based on the results obtained from Western blotting and TEM observation, the deletion of rpoN blocked the synthesis of flagellin and thus the formation of flagellum in YJΔN and YJΔNS. Furthermore, the production of biofilm was twofold more in YJΔS than that other mutant strains after a 24 h-incubation in the LB medium at 30oC, and fivefold more with the incubation in TCG medium. The deletion of rpoS gene in V. vulnificus YJ016 resulted in a slightly decrease in adhering ability to the Caco-2 cells as assessed by competition assay and the LD50 of YJΔS was fourfold more than that of YJ016 in the first 24-hr infection period in the BALB/c mice model generated with a subcutaneous route. Finally, the mutant phenotypes of YJΔS and YJΔN strains observed were completed by providing the rpoS or rpoN gene in-trans. What might be the role of RpoS and RpoN in the infection in Caco-2 cell model and in the regulation of motility for V. vulnificus as well? RpoS and RpoN had been shown to function as both a positive and a negative regulator of expression of different proteins in E. coli and V. cholera. We are trying to figure out the underlying regulatory mechanism by RpoS and RpoN in V. vulnificus, by using a proteomics approach to determine the expression profiling of motility and cytotoxicity associated genes in a panel of mutants generated.


Significance We collected over 1,000 dinosaur eggshell samples from an ∼150-m-thick stratigraphically continuous fossil-rich sequence in the Shanyang Basin of central China, which is one of the most abundant dinosaur records from a Late Cretaceous sequence. We use biostratigraphy of dinosaurs and Bemalambda, magnetostratigraphy, and cyclostratigraphy from orbital cycles to establish a geochronological framework of the dinosaur fossils with a high resolution of 100,000 y. Our results demonstrate low dinosaur biodiversity during the last 2 million y of the Cretaceous, and those data indicate a decline in dinosaur biodiversity millions of years before the Cretaceous/Paleogene boundary. The end-Cretaceous catastrophic events, such as the Deccan Traps and bolide impact, probably acted on an already vulnerable ecosystem and led to nonavian dinosaur extinction.

Applying and extending the Mundell-Fleming model, this study attempts to examine the behavior of short-term real exchange rates for Venezuela. It finds that the real effective exchange rate is positively associated with real government deficit spending and negatively influenced by real M2, the world interest rate, county risk, and the expected inflation rate. Hence, the authorities need to exercise fiscal discipline so that deficit spending would not be too large to cause real appreciation and hurt exports. When country risk rises due to the financial, economic or political factors, real exchange rates would depreciate.


With the rapid development of city greening in the last century, a lot of big trees have been improperly dug up and transplanted over our country, which had resulted in great damage to the ecological environments,the fragile ecological system, and the appearance of 'landscape trash'. Nurseries lag in technology and construction were also presented in the country. In this study, we investigated the present status of some nurseries and city greening by analyzing the causes, the development and the imperilment of improper big tree transplantating. In addition, strategy for improvement was proposed in this paper.


RECENTWORKon this period has reaffirmed that politics should be viewed in terms of a party conflict between Whigs and Tories. During the course of this work, the emphasis has shifted from the level of 'high politics' to that of the grass roots-from the 'men of interest' to the voter. In the last decade a great deal of attention has been paid to the electorate; questions relating to the size and growth of the electorate have led to a revision of earlier estimates, while work on voting behaviour has sought to test the validity of what have been termed the deference and participatory models.l The purpose of this article is to look at the electorate of the two northwestern counties in the light of these lines of inquiry and to see how they were regarded by the 'men of interest' and their agents; to find out to what extent the 'men of interest' could influence the outcome of elections; how far the electorate was deferential to them and to what extent it acted independently. Cumberland and Westmorland have never been densely populated counties, and in the late seventeenth and early eighteenth centuries, the number of families who were active in local politics was quite small. The most powerful local family were the Lowthers; the Westmorland branch owned extensive estates in the west ward of the county and in the sixteennineties also had influence at Carlisle. Sir John Lowther, first viscount Lonsdale, died in 1700 and his successors were both minors. The Cumberland branch lived at Whitehaven, which they developed into an important port and centre of coal mining. James Lowther of Whitehaven first sat in Parliament for Carlisle, where the Lowthers made common cause with another powerful man of interest, Charles Howard, third earl of Carlisle. His Cumbrian seat was at Naworth but his more famous home was Castle Howard. He had extensive influence in northern Cumberland and especially in the city of Carlisle. The Duke of Somerset had acquired large estates in and around Cockermouth by marrying the heiress of the last of the Percies of Northumberland. At Cockermouth he had in the sixteen-nineties a rival

ABSTRACT High resolution measurements of optical birefringence (Δn) have been carried out to study the critical behaviour at the nematic-isotropic (N–I) and smectic A-nematic (SmA–N) phase transitions in a binary system composed of nonyloxycyanobiphenyl (9OCB) and heptylcyanobiphenyl (7CB). From a fitting procedure compatible with the weakly first order nature of the N–I transition, the order parameter critical exponent β at the N–I transition has been found to be in well agreement with the tricritical hypothesis. The pretransitional behaviour at the SmA–N transition has been investigated with the aid of a differential parameter extracted from Δn data and the yielded critical exponent α has been found to be non-universal in nature. A weak birefringence have been found to develop on approaching the N–I transition temperature, which is tentatively attributed to surface induced ordering. In this case, a treatment identical to that for the SmA–N transition yields a tricritical nature for the N–I transition in the investigated mixtures. Such an outcome has also appeared to be in well agreement with those obtained from the direct analysis of the Δn data (i.e. in parameterisation of β). Graphical Abstract


Substoichiometric tungsten oxide nanostructured films were synthesized by a hot-wire deposition technique in hydrogen-rich environment and characterized for their structural and electrical properties. A semiconducting behaviour was identified, allowing n-type conductivity even at room temperature which is an important result since it is well known that fully stoichiometric tungsten trioxide is nearly an insulator. Current–voltage characteristics for various temperatures were measured for tungsten oxide/Si heterostructures and analysed using proper modelling. As a result, the conduction mechanism inside the films was identified and found to be of a dual nature, with variable range hopping being dominant at near room temperatures. The saturation current was found to be thermally activated and the activation energy was calculated at 0.40 eV and the grain boundaries barrier at 150 meV. From Hall measurements it was also revealed that the dominant carriers are electrons and a carrier concentration of about 1014 cm−3 was estimated.


and at times the relevance of contemporary theories seems suspect. Whereas the concept of the "trivial" is fully developed already in the introduction, facets of the Minnereden emerge in more piecemeal fashion, with noteworthy historic, thematic, and linguistic aspects revealed in each essay. At times significant information is relegated to footnotes, e.g., the discussion of the question of genre (p. 2), but this and the occasional unevenness in style and incongruity in terminology, not unexpected in a collection of studies by different authors, detract little from the overall value of the contents. The editors note that the most useful scholarly inquiries into Minnereden were conducted in the 1960s and 1970s, a point substantiated by the references in the introduction and by the literature cited by the contributors. This collection certainly will take its place alongside previous scholarship and should stimulate renewed interest in the texts. Indeed, Lieb and at least one contributor currently are engaged in work on the Handbuch Minnereden, a project of the Fritz Thyssen Stiftung being conducted at the Technische Universität Dresden. More scholarship on these texts is sure to appear in the near future. The volume concludes with brief closing remarks ("Exposé der Tagung"), a list of abbreviations, and three useful indices: one of texts discussed, another of manuscripts and printed versions referenced, and the third with names and topics that appear throughout the volume. In their summary of the conference discussions, the editors identify two foci: one analyzing the "trivial" as text-immanent and the other examining its functions in cultural practice (p. 260); they reiterate key points in the essays and catalog questions left unanswered by them. Not surprisingly, there is the suggestion that methods and arguments employed with regard to Minnereden might be of benefit in the study of other types of literature that flourished in the late Middle Ages, such as Meistersang. The conclusion drawn by the conference organizers and participants will undoubtedly be echoed by readers of this volume: although the Minnereden may be identified as Trivialliteratur, they are anything but trivial.

Genus Ceropegia L. (family - Apocynaceae) includes herbs and climbers grow in tropical and sub-tropical regions of the World with more than 220 species. They have acquired significant importance due to their medicinal properties, edible tubers, and its ornamental flowers. However, utmost species are suffering from various threats such as hydroelectric projects, wind mills, deforestation, clamming of more and more land for agriculture, introduction of exotic species, spread of invasive weeds, forest fires, tourism and increased habitat fragmentation. Due to these reasons, their conservation and further improvement through biotechnological approaches are unavoidable. Using tissue culture techniques, it is possible to produce large number of plants throughout the year under controlled growth conditions in a small space. Thus the study was attempted on endemic and endangered Ceropegia species from Western Ghats. The study determined the adventitious shoot regeneration, callus culture, somatic embryogenesis, in vitro flowering, molecular profiling and reintroduction of in vitro regenerated plantlets in to their natural localities.


The chemical composition of copper alloys from Bronze Age site of ancient Margiana (ancient delta of Murghab river, Turkmenistan) Gonur Depe were studied by mass spectrometric analysis (ICP-MS) for 63 elements. Four types of alloys are identified. Chemical composition of the parent metal of five fully oxidized items were completely reconstructed by developed technics. This allowed to compare them with other metal artifacts of the area. It is shown that the typical Gonur copper alloys can also be differentiated by their micro-composition into smaller subgroups. Spectral analysis traditionally used to determine the chemical elemental composition of the products of copper alloys allows to determine mainly macro-composition of the alloy and only a few elements of micro-composition. The quantitative content of copper alloy matrix is not defined by it. ICP-MS multielemental analysis has much more possibilities in terms of accuracy, sensitivity, and the number of elements determined in comparison with spectral analysis. By our method it allows to quantify 63 elements: Li Be Na Mg Al Si P K Ca Ti Cr Mn Fe Co Cu Zn Ga Ge As Se Rb Sr Y Nb Mo Ru Pd Ag Cd In Sn Sb Te Cs Ba La Ce Pr Nd Sm Eu Gd Tb Dy Ho Er Tm Yb Lu Hf Ta W Re Pt Au Hg Tl Pb Bi Th U. Chemical element composition of the copper alloys products from Gonur by ICP-MS was not studied yet. We have studied 10 samples of artifacts from various places of Gonur Depe by ICP-MS: fragments of pins, seals, bracelets, mirrors, plates, unknown object and metallurgical slag, found by Margiana archaeological expedition (under the direction of V.I. Sariandi) in 1988, 1994 and 2010. As some artifacts were completely oxidized a special technique of reconstruction of the chemical composition of the parent metal by the chemical composition of the oxidized copper alloys has been developed. The oxygen content in the oxides and the initial chemical composition of copper alloys of five artifacts were determined by calculation. The chemical composition on 63 elements which was determined by the ICP-MS analyses is presented for all the studied artifacts. In this collection of copper-bronze artifacts of Gonur Depe we identified four types by macro-composition: copper (Cu), arsenic bronze (Cu-As), tin bronze (Cu-Sn), lead-bismuth-arsenic bronze (Cu-Pb-Bi-As). Criteria of similarity and difference by micro-composition allow additionally dividing these types of alloys into several subgroups and clarify the genesis of copper alloys of Margiana.


New lactose-or D-galactose-containing diethylenetriaminepentaacetic acidbisamide ligands and their gadolinium complexes were synthesized by the reaction of bis(N-hydroxysuccinimide ester)of diethylenetriaminepentaacetic acid with amino-containing lac-tose or D-galactose derivatives. Chemical structures of ligands and Gd complexes were char-acterized. In vitro spin-lattice relaxivity and acute toxicity in mice of the complexes havebeen preliminarily investigated. Magnetic Resonance lmaging for rabbit shows that the con-trast agent bearing galactose could be targeted to the liver.


3189 Background: PABA or p-amino benzoic acid is a water-soluble natural compound and a component of Vitamin B-12, thought to play a role in nucleotide base synthesis. It is widely available as a dietary supplement and is a common component of sunscreens. Previously, we observed that PABA enhanced the effects of radiation in B16F10 and G361 melanoma and Lewis Lung carcinoma in vitro, as well as in 4T1 breast carcinoma and B16F10 melanoma in a chick CAM in vivo model (ACR-NCI-EORTC, Nov. 2003). To further explore the role of PABA pre-clinically, we studied its effects as a radiosensitizer in the 4T1 syngeneic murine model of mammary carcinoma (Fred Miller, The Michigan Cancer Center). Methods: 4T1 tumor cells (5 x 104) were injected subcutaneously into the flank of BALB/C mice. Three days later, 28 mice were randomly assigned to PABA, administered daily for the duration of the experiment (1 mg/day), or no PABA treatment. At 14 days post-implantation, a randomization to radiation treatment (RT) occurred in ...


PURPOSE
Stereotactic radiosurgery is an alternative option to neurosurgical excision in the management of patients with brain metastases. We retrospectively analyzed patients with brain metastases of malignant melanoma who were treated at our institution for outcome and prognostic factors.

PATIENTS AND METHODS
64 patients with 122 cerebral metastases were treated with stereotactic radiosurgery between 1986 and 2000. Twelve patients (19%) showed neurologic symptoms at the time of treatment, and 46 patients (72%) had extracerebral tumor manifestation at that time. The median dose to the 80% isodose line, prescribed to encompass the tumor margin, was 20 Gy (range, 15-22 Gy).

RESULTS
Neurologic symptoms improved in five of twelve symptomatic patients. 41 patients remained asymptomatic or unchanged in their neurologic symptoms. Only five patients (8%) temporarily worsened neurologically after therapy despite no signs of tumor progression. With a mean follow-up time of 9.4 months, actuarial local control was 81% after 1 year. There was a statistically significant dose and size dependency of local tumor control. Median actuarial survival after treatment was 10.6 months. Patients without extracerebral tumor manifestation showed a superior survival (p = 0.04).

CONCLUSIONS
Despite high local tumor control rates, the prognosis of patients with cerebral metastases of malignant melanoma remains poor. Stereotactic radiosurgery has the potential of stabilizing or improving neurologic symptoms in these patients in a palliative setting.


Hypovitaminosis D is common in the Italian population and has a comparable effect to diabetes mellitus on survival after an acute myocardial infarction (AMI). We aimed to evaluate if the prevalence of hypovitaminosis D changed over time, considering also frequent lockdowns in the last years due to COVID-19 pandemic.

 According to the year of enrollment, we divided our cohort of 1042 patients hospitalized for AMI, into three groups (group 1 with 368 patients enrolled from 2014 till 2016, group 2 with 470 patients enrolled in the period from 2017 till 2019, and group 3 including 204 patients enrolled in the last three years, from 2020 till 2022) and evaluate whether the concentration of vitamin D changed in the last decade.

 The median concentration of vitamin D in our cohort of patients with AMI was 18.2 (11.48-25.73) ng/ml). Throughout the three groups (2014-2016, 2017-2019, 2020-2022), the median plasma vitamin D showed a trend toward an increase (17.3 (10.33–24.2) ng/ml, 18.95 (11.6–26.73) ng/ml, and 19.05 (12.5–27.3) ng/ml respectively), which was significant between the group 1 vs 2 and 3 (p = 0.033 and p = 0.004, respectively), while between the group 2 and 3 did not. Despite the trend of increase, the percentage of patients with hypovitaminosis D in each group remained high (61.4%, 53.8% and 52.0% respectively). As expected, samples taken between May and September have significantly higher vitamin D values compared to ones taken from October to April for each group (the group 1: 21.80 (15.55–31.23) ng/ml vs 15.8 (9.22–23.98) ng/ml, p < 0.0001; the group 2: 22.05 (14.10–30.98) ng/ml vs 16.50 (11.03–23.90) ng/ml, p < 0.0001); the group 3: 20.00 (11.90–26.90) ng/ml vs 16.30 (9.75–22.30) ng/ml, p = 0.001).

 There has been a trend of increasing vitamin D values over the years, but hypovitaminosis D remains frequent. During the pandemic, vitamin D levels did not decrease due to frequent lockdowns, possibly due to media awareness that emphasized the significance of vitamin D administration against viral infection.


Geodetic observations of interseismic deformation across the Tibetan plateau contain information about both tectonic and earthquake cycle processes. Time‐variations in surface velocities between large earthquakes are sensitive to the rheological structure of the subseismogenic crust, and, in particular, the viscosity of the middle and lower crust. Here we develop a semianalytic solution for time‐dependent interseismic velocities resulting from viscoelastic stress relaxation in a localized midcrustal layer in response to forcing by a sequence of periodic earthquakes. Earthquake cycle models with a weak midcrustal layer exhibit substantially more near‐fault preseismic strain localization than do classic two‐layer models at short (<100 yr) Maxwell times. We apply both this three‐layer model and the classic two‐layer model to geodetic observations before and after the 1997 MW = 7.6 Manyi and 2001 MW = 7.8 Kokoxili strike‐slip earthquakes in Tibet to estimate the viscosity of the crust below a 20 km thick seismogenic layer. For these events, interseismic stress relaxation in a weak (viscosity ≤1018.5 Pa⋅s) and thin (height ≤20 km) midcrustal layer explains observations of both preseismic near‐fault strain localization and rapid (>50 mm/yr) postseismic velocities in the years following the coseismic ruptures. We suggest that earthquake cycle models with a localized midcrustal layer can simultaneously explain both preseismic and postseismic geodetic observations with a single Maxwell viscosity, while the classic two‐layer model requires a rheology with multiple relaxation time scales.


Abstract : This paper comprises a review of the contribution of the small- and medium-sized manufacturing business sector to the US defense industrial base, the state of adoption of modern process technology in small- and medium-sized manufacturing in five industry groups, a review of the National Institute of Standards and Technology's Manufacturing Technology Program and its performance evaluation processes, and recommendation for features of future DOD manufacturing improvement programs.


An updated analysis of all available neutrino oscillation evidence in Reactor (Kamland, first 145 days of data) and Solar experiments (SK day and night spectra, global rates from Homestake, SAGE and GALLEX) including the SNOCC and NC data is presented. In the framework of two active neutrino oscillations we determine the allowed regions in neutrino parameter space, we obtain, from the Kamland spectral shape and global signal, the following antineutrino best solution parameters, ∆mkl = 7.7 × 10−5eV 2, tan2 θkl = 0.98. The overall effect of the measured observed ratio R ∼ 0.6 is that the LMA region remains the only one which is still favored. Combining Kamland and Solar data and assuming CPT invariance, i.e. the same mass matrix for neutrino and antineutrinos, we obtain the following antineutrino best solution parameters (LMAI solution), ∆m2 = 7.1 × 10−5eV 2, tan2 θ = 0.47. A second solution (LMAII) appears for values ∆m2 = 1.5×10−4eV 2, tan2 θ = 0.48. We determine additionally individual neutrino mixing parameters and their errors from fits to marginal likelihood distributions, the values are compatible with previous results. In both methods, χ2 minimization and marginal likelihood, the combined analysis of solar and Kamland data concludes that maximal mixing is not favored at the ∼ 3σ level at least.

The article is concerned with one of the newest trends in literary studies championed by the journal Translit . The 'new poetics' promulgated by the journal, as well as the underlying 'pragmatic theory of literature', means rejection of the aesthetic focus in writing. In its crusade against the 'aesthetic ideology' the journal adopts an extreme form of relativism and adheres to the theory of power struggle between elites as the key driver of social relationships. The author argues that attachment of a fetish status to writing tools (especially the most fashionable electronic ones), dismissal of 'anthropocentricity' in favour of 'posthumanism' by pragmatic theorists, and an aggressive search for 'epistemological and political enemies' are a cause for a major concern in the contemporary cultural crisis.

Resistance to vemurafenib remains one of the cardinal challenges in melanoma therapeutics, and the lack of a good animal model of vemurafenib resistance is one of the difficulties in deeper investigations of the problem. In this industry-supported study, investigators created such a model of the emergence of drug resistance — an early passage, tumor xenograft derived from human patients that had the BRAF V600E mutation and that was implanted in immunocompromised mice, which were then continuously …


In studying the characteristics of cultures, literature and philosophies of different civilisations, scholars inevitably wish to search for similar and different features inherent in particular societies. When this desire is completely justified, then certain questions remain that require additional reflection. For instance, studying the cosmological and natural-philosophical ideas inherent in Ancient China and among Native Americans, scholars face the difficult task of logically substantiating the possibility of studying these two diametrically opposed cultures together. This article is based on a general overview of cosmological and philosophical views in Ancient China and among Native Americans. The authors reveal an important principle that significantly distinguishes "non-Western" cultures and manifests itself in ethnocentrism and harmonization of the relationship between humans and nature (Feng shui).

This paper considers the narrow question of whether, in a wrongful death context, the right of survivors to recover damages should be based on gross family income and household production or be limited to the income and household production of a decedent. It focuses on the interface between forensic economics and the literature of family economics. It suggests that the family bargaining literature could address measurement questions that are important to forensic economics.

Vaccines for protecting cattle against bovine leukemia virus (BLV) are prepared by in vitro culturing of lymphoid cell lines derived from bovine or ovine lymphosarcoma tissue. The cell lines are characterized by being non-producers of BLV. The vaccines and their method of preparation can also be used for protecting sheep against bovine leukemia virus.


The interactions between two macroscopic walls immersed in an isotropic symmetric sponge phase (L 3 ) at different volume fractions, Φ, were studied with a surface force apparatus. At temperatures well below the lamellar (L α )/L 3 bulk transition, the force-distance profile is weakly oscillatory with a period that is twice the correlation length (ξ) of the L 3 phase measured from SAXS. The oscillations are superimposed on an exponentially attractive background with an order correlation length of 2-4 cell sizes of the sponge structure


An edge enhancement filter is proposed for denoising and enhancing images corrupted with data-dependent noise which is observed to follow a Gamma distribution. The filter is equipped with three terms designed to perform three different tasks. The first term is an anisotropic diffusion term which is derived from a locally adaptive p-laplacian functional. The second term is an enhancement term or a shock term which imparts a shock effect at the edge points making them sharp. The third term is a reactive term which is derived based on the maximum a posteriori (MAP) estimator and this term helps the diffusive term to perform a Gamma distributive data-dependent multiplicative noise removal from images. And moreover, this reactive term ensures that deviation of the restored image from the original one is minimum. This proposed filter is compared with the state-of-the-art restoration models proposed for data-dependent multiplicative noise.

This thesis has two aims: to expand scholarly understanding of the Iranian Revolution up to its transition to religious totalitarianism, and second, to present a non-deterministic theoretical framework for understanding revolutions more generally, which incorporates both structure and agency. Relying on a combination of extended interviews with leading participants and some hitherto unused primary sources, and with the help of secondary texts, it reconstructs the intense political struggles from 1979-81 and the ideological formations which shaped the revolutionary process, in four steps: (1) an analysis of the ideological foundations of competing discourses of Islam, in particular those of Khomeini, Shariati, Motahari, Bazargan and Banisadr; (2) a narrative of historical events and socio-economic and political changes which set the stage for the Iranian Revolution; (3) a narrative of the process of revolution itself; and (4) a narrative of the emergence of political struggle within the revolutionary movement, which drew on two competing discourses of Islam, those of power and of freedom. The analysis of this evidence seeks to demonstrate that dictatorship was not an inevitable consequence of the revolution, but due to four main causes: (1) lack of unity within the democratic camp, (2) poor use of available resources and opportunities, (3) specific, critical decisions, and finally (4) international factors. It also suggests a theoretical framework which makes it possible to critically analyse the process of revolution, which takes account of unique socio-historical contingencies.


Background: Indolent B cell non-Hodgkin lymphomas (B-NHL) are typically described as having smoldering clinical courses. Chemotherapy plus CD20-targeting antibodies have made remissions in this type of disease possible, with fit patients sometimes consolidated with autologous stem cell transplant. However, these lymphomas commonly progress or relapse inexorably, requiring further interventions. Some B-NHL subtypes, such as mantle cell lymphoma (MCL) or advanced follicular lymphoma (FL) have unpredictable and sometimes clinically aggressive courses which are refractory to even frontline treatments, and remain principally incurable.
 Adoptive chimeric antigen receptor T cells targeting CD19 (CD19.CAR-T) has shown therapeutic promise for these B-NHL subtypes. Targeting this antigen, however, does not distinguish between normal and malignant B cells and may cause B-cell aplasia and agammaglobulinemia when CD19.CAR-T persist long-term. FL and MCL, along with many diffuse large B cell lymphoma (DLBCL), express surface immunoglobulin (Ig) that is clonally restricted to either the kappa (Ig-κ) or lambda (Ig-l) light chains. We explored targeting the Ig-κ or Ig-l individually with CAR-T, which would possibly spare B lymphocytes expressing the reciprocal light chain, and consequently reduce the impairment of humoral immunity.
 Methods/Results: Previous studies showed modifying the hinge and transmembrane (TM) regions could result in amplified tumor cytotoxicity. We explored refining our own CAR-T approach by first altering the hinge and TM regions of the CAR molecule itself, using the CD8a hinge and TM regions in lieu of the currently used CD28 hinge and TM sections. The costimulatory endodomains used were either CD28 or 41BB, each combined with the CD3ζ chain. When compared to the CD28 hinge and TM containing CAR molecules, we demonstrated the CD8a-containing hinge and TM CAR molecules targeting Ig-κ (CAR.κ) or Ig-l (CAR.λ) had augmented cytotoxicity, as well as increased IFNg and IL-2 cytokine production, in vitro against B-NHL derived tumor cell lines expressing Ig-κ or Ig-l, respectively. Furthermore, both CAR.κ and CAR.λ demonstrated selective cytotoxicity of the appropriately expressed tumor-associated immunoglobulin, while sparing the tumor cells expressing the reciprocal surface Ig.
 We conducted in vivo experiments using a NOD-scid gamma (NSG) xenograft murine models. NSG mice were treated with CAR-T targeting CD19 (positive control), non-transduced cells (negative control), and depending on the Ig light chain target, either CAR.κ.CD28ζ and CAR.κ.41BBζ, or CAR.λ.CD28ζ and CAR.λ.41BBζ. We also established a humanized murine model that reconstituted human B lymphocytes in NSG mice post-irradiation using CD34+ umbilical cord blood cells, replicating a humanized humoral immune system replete with a full complement of humanized B cells. We then measured the selective ability of CAR.κ and CAR.λ cells to eliminate human B-lymphocytes expressing either the Ig-κ or Ig-l, respectively, while sparing the reciprocally expressed light chain-carrying B lymphocytes.
 We found that CAR.κ and CAR.λ showed respective high cytotoxic activity, similar to CD19.CAR, against the appropriate Ig-κ+ or Ig-l+ B-NHL tumor cell lines in vivo within the NSG xenograft murine model. We also demonstrated the selective elimination by the CAR.κ and CAR.λ of either the kappa or lambda light chain-expressing B lymphocytes, with sparing of the reciprocal light chain-expressing B lymphocytes, in the humanized murine model.
 Conclusion: Since κ/l expression is clonally restricted, and because mature B-lymphocyte derived malignancies are themselves clonally restricted, having a CAR-T that targets either light chain can potentially treat the full gamut of mature B-NHL subtypes. In addition, sparing the normal population of B lymphocytes would have negligible impact upon the patient's humoral immunity. Moreover, we showed equal efficacy of our CAR.κ.CD28 and CAR.λ.CD28 when compared with CD19.CAR. As such, adoptive transfer of CAR-T targeting the clonally restricted light chain can be a very feasible immunotherapy approach to treating advanced FL, MCL and DLBCL clinically, without entirely compromising humoral immunity.

An equivalent circuit model of an ultra-thin metamaterial absorber comprising a square-ring-shaped frequency selective surface (FSS) is presented. The model can be considered as series RLC resonators connected in parallel with coupling capacitance and short-circuited transmission line. The even- and odd-mode couplings have been incorporated to accurately determine the lumped parameters as well as the absorption frequency of the absorber structure. The effects of substrate thickness and dielectric permittivity variation on the lumped parameters and full width at half-maximum (FWHM) bandwidth are investigated based on the proposed model. The absorber has been fabricated, and close matching among the calculated, simulated, and measured results has been observed.


Deep learning has achieved great success in various areas and its success is closely linked to the availability of massive data. But in general, a large dataset could include sensitive data and therefore the model should have the capability to avoid privacy leakage. To achieve this aim, many works apply the famous privacy framework named differential privacy into deep learning to preserve privacy. In this article, we propose a novel perturbed iterative gradient descent optimization (PIGDO) algorithm and prove that this algorithm satisfies the differential privacy. Besides, we propose a modified moments accountant (MMA) method to conduct the privacy analysis and obtain a tighter bound of privacy loss compared with the original moments accountant method. A number of experiments demonstrate that our optimization algorithm can not only improve the model accuracy and training speed, but also achieve better privacy guarantees over the state-of-the-art algorithm while reaching the equivalent accuracy. We provide codes for all of our experiments in https://github.com/CGCL-codes/DPDLIGDO.git.


The ({alpha},{sup 3}He) and ({alpha},{ital t}) reactions on {sup 16,17,18}O were studied at {ital E}{sub {alpha}}=65 MeV. Measured cross sections for the states up to 15 MeV in the residual nuclei were analyzed with the distorted wave Born approximation theory. Many spin-parity and isospin assignments were proposed based on the strengths, angular distributions, and excitation energies. Nearly equal spectroscopic factors were obtained for bound and unbound analog pairs except for the 2{sub 1}{sup +}, {ital T}=1 states in {sup 18}O and {sup 18}F. Almost full strengths were observed for the 0{ital d}{sub 5/2}, 1{ital s}{sub 1/2}, and 0{ital d}{sub 3/2} transfers. The obtained spectroscopic factors for the 0{ital d}{sub 5/2} and 1{ital s}{sub 1/2} transfers were in good agreement with shell-model calculations, while the agreement was unsatisfactory for the 0{ital d}{sub 3/2} transfer in many respects. The {ital d}{sub 3/2} strengths in {sup 17}O and {sup 17}F were more fragmented than the shell-model prediction, while only half of the expected 0{ital d}{sub 3/2} strength was found in {sup 18}O and {sup 19}O. The strength to the first excited 3/2{sup +}, {ital T}=1/2 state in {sup 19}F was twice that predicted. Spectroscopic factors for many 0{ital f}{sub 7/2} transitions were alsomore » deduced. The 14.1 and 14.3 MeV states in {sup 18}O, in particular, proposed to be the stretched 6{sup {minus}} states in a recent ({ital e},{ital e}{prime}) experiment, were found to be excited by pure {ital l}=3 transfer with spectroscopic factors 0.16 and 0.05, respectively.« less

Objective To study the expression of syntaxin 4 and interaction with other related proteins in human NK cells and to create a new idea to interfere the exocytosis in NK cytotoxin process. Method We examined the syntaxin 4 gene by RT PCR, the protein expression of syntaxin 4 in resting and activated NK cells by Western blot, the relocation of syntaxin 4 in resting and activated NK cells by indirect immunofluorescence and the interaction with SNAP 23 by coimmunoprecipitation. Results Syntaxin 4 is expressed both at mRNA and protein level. It is primarily located in cytomembrane dispersively and concentrated as a cap after stimulation by PEC. Coimmunoprecipitation assays indicated that syntaxin 4 interacts with SNAP 23 in vivo . Conclusion Syntaxin 4 is concerned with the recognition of target cell in transplantation rejection and interacts with the signal transmitter, SNAP 23. So, it may act as a target molecule in the regulation of exocytosis in NK cytotoxicity.


The change has been a constant phenomenon in librarianship. However, it has been comparatively very slow in developing countries like Pakistan, where a need to prepare professionals with a blend of traditional and modern skills is still there. Presently, eight universities have been offering regular programs in LISE. However, there are serious quality issues regarding faculty, curriculum development, infrastructure, assessments, etc. in these programs. Nonetheless, for the last few years, the Higher Education Commission (HEC) of Pakistan is pushing hard to induce and maintain the quality of higher education. The paper gives a brief account of the present scenario of post-graduate LIS programs, identifies the basic issues regarding quality library and information studies education (LISE) in Pakistan, and suggests the possible measures for QA in Pakistan. The multi-method approach was used to collect the data for this study based on survey, interviews, focus group, discussions with peers and observation and experience of the author.

The influence of nanofillers on thermophysical properties of epoxy-polyester composites has been investigated in the work. The filler content (oxidized nanodisperse additive and pyrogenic silicon dioxide) has been varied within q = 0.02…1.0 pts.wt. per 100 pts.wt. of epoxy oligomer ED-20. It has been discovered that the introduction of the oxidized nanodisperse additive in the amount of q = 0.05…0.08 pts.wt. into the epoxy-polyester binder leads to an improvement in the thermophysical properties of the composite. Value of heat resistance (according to Martens) increased from Т = 335 К (for the epoxy-polyester matrix) to T = 346 K at the content of oxidized nanodisperse additive of q = 0.075 pts.wt. Introduction of q = 0.05 pts.wt. of oxidized nanodisperse additive allows to obtain improved values of the temperature coefficient of linear expansion in different temperature ranges: in the region ΔT = 303…323 K – α = 1.0 × 10-5 K-1, in the region ΔT = 303… 373 K - α = 1.9 × 10-5 K-1, in the region ΔT = 303… 423 K – α = 3.4 × 10-5 K-1. It has been determined that the composite material has also improved its heat resistance (according to Martens), which is T = 347 K and the minimum thermal coefficient of linear expansion at the content of q = 0.05 pts.wt. of pyrogenic silicon dioxide nanofiller. Values of the temperature coefficient of linear expansion were: α = 1.0 × 10-5 K-1 in the region (ΔT = 303… 323 K), α = 1.9 × 10-5 K-1 (in the region ΔT = 303… 373 K), Δα = 3.4 ×× 10-5 K-1 (in the region ΔT = 303… 423 K), α = 8.4 × 10-5 K-1 (in the region ΔT = 303… 473 K). It is recommended that in order to form a composite material with improved thermophysical properties to protect the elements of ship technical equipment, it is advisable to introduce the pyrogenic silicon dioxide nanofiller in the amount of q = 0.05 pts.wt. into the epoxy-polyester binder.


ABSTRACT The higher fragment sizes (>2,100 bp) are not observed in the two C. spp. populations. The six oligonucleotides primers OPA-11, OPB-09, OPB-14, OPB-20, OPC-14, and OPC-18 were used to generate the unique shared loci to each tonguesole population and shared loci by the two tonguesole populations. The hierarchical polar dendrogram indicates two main clusters: Gunsan (GUNSAN 01–GUNSAN 11) and the Atlantic (ATLANTIC 12–ATLANTIC 22) from two geographic populations of tonguesoles. The shortest genetic distance displaying significant molecular difference was between individuals' GUNSAN no. 02–GUNSAN no. 01 (genetic distance=0.038). In the long run, individual no. 02 of the ATLANTIC tonguesole was most distantly related to GUNSAN no. 06 (genetic distance=0.958). These results demonstrate that the Gunsan tonguesole population is genetically different from the Atlantic tonguesole population. The potential of PCR analysis to identify diagnostic markers for the identification of two tonguesole populations has been demonstrated. As a rule, using various oligonucleotides primers, this PCR method has been applied to identify polymorphic/specific markers particular to species and geographical population, as well as genetic diversity/polymorphism in diverse species of organisms.

A group connected HVDC transmission scheme is a variant of the unit connection where instead of a single generator, a group of generators are directly connected to the power converter. Studies conducted in the past indicated that significant cost reduction can be achieved using this scheme. This is mainly due to the elimination of many components which results in considerable capital and operating cost savings to the utility. Concerns regarding the reliability performance of unit connected schemes were raised, however, there has not been a detailed reliability study conducted. This paper addresses the reliability evaluation aspect of a group connected scheme and compares the reliability performance of the group connected scheme with that of the conventional common collector system. Reliability models for both schemes were developed using a hypothetical model based on the Nelson River power system. Practical power system component outage data was used to examine the reliability performance of both schemes. >


Abstract Ferroelectric materials are rather exactly specified for small signal application by their linear elastic, dielectric and electromechanical coefficients. However, an unambigeous characterization cannot be given by these means if a high mechanical or electrical power level is applied. Further the study of the large signal behaviour is important for the understanding of structural phase transitions of ferroelectric materials (ceramics, crystals and thin films). The aim of the present paper is to show that the application of methods of nonlinear dynamics, e.g. spectrum- and time series analysis, is a useful tool for studying this large signal behaviour. Investigations concerning the nonlinear behaviour of ferroelectric materials were performed in a wide range of parameters of a driven series resonance circuit. The bifurcation cascades, the periodic and chaotic phase portraits and the Poincare sections were used for the determination of the nonlinear coefficients of the sample.

Tool presentation: When formally verifying models of cyber-physical systems, it is obviously important that their verification results can be transferred to all previous observations of the modeled systems. Our tool CORA makes it possible to transfer safety properties by checking whether all measurements of the real system lie in the set of reachable outputs of the corresponding model -- we call this reachset conformance checking. In addition, we provide strategies to establish reachset conformance by injecting nondeterminism in models. This can be seen as some form of system identification, where instead of finding the most likely parameters, we compute a set of parameter values -- not only for the model dynamics but also for the set of disturbances and measurement errors -- to establish reachset conformance. By replacing real measurements with simulation results from a high-fidelity model, one can also check whether a high-fidelity model conforms to a simple model. We demonstrate the usefulness of reachset conformance by several use cases.

Recent contributions to the issue of countervailing power have formally demonstrated that imperfectly competitive market structures in retailing have different welfare implications from those hypothesized by Galbraith (1952) according to which increasing concentration in retailing may offer social benefits. Recent works in this area show that greater concentration at the retail level may afford retailers a simultaneous increase in both their buying and selling power. Whilst the former improves their relative bargaining position, the latter allows for increased price-cost margins. This recent literature suggests that retailing concentration may have a negative impact on consumer welfare since the effect of increased price-cost margins is sufficiently greater than the downward pressure on intermediate prices generated by increases in retailers' 'buying power'. As a result, greater concentration at the retail level may lead to higher final prices and lower social welfare. In this paper, we argue that the bargaining models of the manufacturer-retailer relationship used in these works take into account only partially the sources of retailers' bargaining power. In fact, they include only the source associated to the number of retailers. However, as indicated by a massive trade and applied literature, several factors determine the relative bargaining power of manufacturers and retailers. One crucial factor is given by the presence of vertical competition between manufacturers' brands and retailers' private labels. This form of competition represents a further source of bargaining power for retailers which may reinforce the buying power effect and imply conclusions more favorable to the countervailing power hypothesis. To explore this hypothesis, we develop a model which differs from previous ones by focusing on market settings where vertical competition affects the relative bargaining positions and bargaining outcomes. The paper examines the negotiation process between a manufacturer and N retailers on the transfer price as a Nash bargaining game and determines the outcome by the Nash bargaining solution. We assume that vertical competition decreases the profit levels and the disagreement payoff of the manufacturer. We also assume that vertical competition increases the disagreement payoff of retailers while their profits remain unchanged. It is shown that vertical competition increases retailers' bargaining power, reduces equilibrium transfer prices and hence equilibrium retail prices. In particular, our results show that final prices are lower when vertical competition is more intense for any given number of retailers. This means that the higher bargaining power associated to vertical competition plays a positive role for consumers when their interest is measured in terms of retail prices.

In this paper a Relational Oriented Systems Engineering and Technology Tradeoff Analysis (ROSETTA) framework is introduced for performing technology tradeoff and design studies with respect to the live, virtual and constructive mixes for aircrew training. This novel, efficient and model driven repeatable approach to the present and future problem of live / synthetic mixes on-board a real aircraft concentrates on relationships between elements in models to support capability based decisions. The methodology described provides a framework and factorization of a family of systems (FoS) architecture for tactical situation/mission scenario and evaluation of pilot response models. ROSETTA provides a more rigorous mathematical framework for conducting decision support and advances current model based systems engineering (MBSE) process for simulation and analysis of a complex system of systems (SoS) problem.

The expression of DJ-1, PTEN and AR were detected by Western blotting. Transwell assay was used to detect 231 cells migration and invasion after transfected pEGFP/DJ-1. The expression of DJ-1 in non-hormone-dependent breast cancer patients with or without metastasis was evaluated by immunohistochemistry. 【Results】 After transfection of pEGFP/DJ-1, the expression of DJ-1 and AR were evaluated,but the PTEN expression was decreased. Transwell data showed that pEGFP/DJ-1 promoted MDA-MB-231cells migration and invasion. And the expression of DJ-1 in non-hormone-dependent breast cancer patients with metastasis(85.0%) was higher than the persons without metastasis(55.0%). 【Conclusion】 Over-expres-sion of DJ-1 promotes non-hormone-dependent breast cancer MDA-MB-231 cells migration and invasion through by depressing PTEN expression and activated AR expression.


Benefits of federation are in more flexible use of the social and economic potential of its subjects at wide inter-regional competition. The federal system allows to use effects of either greater economic space or more complete considering of local conditions and interests. Specificity of modern Russian federalism lies in the history of the formation and organization of its space. Russian history is a history of over-centralized state, which however considered the specificities of individual territories . Introduction of federalism in a state management practices in Russia in early 1990s. occurred in the wave of democratization, but excluding the condition of Russian economy and inherited status of the Russian state space. Strong regions won from the devolution to the RF regions, but it was the result of unequal conditions in which the subjects of the federation were in the market transformation and dissolution of the USSR. Among economic reasons of recentralization in 2000 are growing regional disparity , payments crisis, regional protectionism , the contradictions between the center and the regions about the financial and production assets . In the most critical moment of market transformation economic disintegration of the space of the country began to amplify. Business - elite close to the authorities , seek to free hands in resources development and their export. Request to strengthen the central government came also from the management of economically weak RF subjects who needed financial support from the federal budget. After the restoration of the vertical of power in relations with the regions intergovernmental transfers became the main instrument of the federal government. Huge volume redistribution operations have become a key element of regional policy . Built vertical power was aimed at neutralizing possible political and social consequences of divergence space growth, but not the reasons for its cause. Today federal relations are in a certain accordance with a level of the Russian economy and its spatial structure. The introduction of more democratic forms of federalism without appropriate technological and structural changes in the economy of the RF subjects can create more problems than positive effects. To change the system of power , it is necessary to change a space and the technological base of the economy. Change of the space requires joint efforts of all levels of government and local communities. The task of the central government is to organize their partnership , using political , economic and social institutions .

Model systems for studying thin-film cracking consisting of thin plates of alumina and soda-lime glass were diffusion bonded to silica substrates at high temperature. Upon slow cooling, substrate fracture was induced by residual stresses from the thermal and elastic mismatch of the film and substrate. In particular, multiple substrate cracks formed parallel to the interface. The observed crack paths closely followed predictions based on a zero mode II stress intensity. Crack depths were found to be strongly dependent on the relative substrate thickness and the Young's modulus ratio.

This paper examines the influence of geoeconomic policies on development. The new age is characterized by not political or ideological rivalry but by economic competition. States do not aim at conquering lands but rather at dominating and controlling markets. That process brings the discussion that the age is whether a geoeconomic age or a neo-mercantilist age with the writings of pundit writers of geoeconomics in terms of the economic policies of developed and developing countries. In the geoeconomic world developed countries mainly apply neo-mercantilist policies towards the developing countries, and as a response developing countries that were "second orders" or "middle powers" of the geopolitical era generate their own regional geo-mercantilist policies and closer economic relations with neighbor countries. Turkey's strategic and geopolitical importance is continuing with its geoeconomic importance in the new era. Since the 1980s Turkey's growth and industry-oriented policies have shifted from the realm of public policy to a market-driven domain. And later, with the collapse of the USSR and the end of the Cold War, the "Iron Curtain" around Turkey has absented. These two transformations gave Turkey a great chance with her historical, cultural and economic ties to form a geoeconomic space and to become an engine of regional development. This study investigates the importance of Turkey for regional development with its geoeconomic policies in terms of energy. trade, and investment policies. Turkey as a bridge or a frontier between East and West could play an effective role. For Eastern Europe, Turkey will create a catalyst effect as a bridge, however, its effect will be an impediment as a frontier.

Major medical needs may be achieved through regenerative medicine. Nanotechnology has triggered a research revolution in many important areas such as the biomedical sciences and bioengineering at the molecular level which has grown significantly due to the availability of new analytical applications and tools based on nanotechnology. Clinical conditions and diseases being targeted by nanotechnology research include burns, Alzheimer's and Parkinson's disease, implant failure, improved wound healing, birth defects, osteoporosis and congestive heart defects. Therapeutic use of growth factors and drugs to stimulate the production and/or function of endogenous cells represents a key area of regenerative medicine. The development of methods to expand ex vivo and drug delivery through advances in cell culture and scaffold technology have led to successful new treatment modalities for bone and wound repair. The studies in this dissertation focused on several regenerative medicine approaches, with a future goal of an implantable scaffold material that can efficiently act as a repair material for wound healing and repair or as a replacement material for bones, teeth and other tissues. In this study, two different materials were nanoengineered for regenerative medicine applications. Anodization was used to produce nanoporous titanium scaffolds. Electrospinning was used to form Poly (e-caprolactone) (PCL) scaffolds, halloysite-PCL composite scaffolds and drug loaded halloysite-PCL scaffolds. Cellular response was assessed in each study through cell-based assays, including the


Shimmer is a collection of poems that explores the unfixed nature of self-construction through the complications of intersectionality. Throughout the text, the speaker, possessing multiple positions that share the locus of the singular unified body, navigates existing power structures in various publics in which bodies and cultures are read and deemed legible or illegible to situated hegemonic social structures. Through confessional and lyric strategies, the speaker reflects on the rituals that reify culturally informed social contracts within diverse publics.


The polar precursor method is widely considered to be the most robust physically motivated method to predict the amplitude of an upcoming solar cycle. It uses indicators of the magnetic field concentrated near the poles around sunspot minimum. Here, we present an extensive performance analysis of various such predictors, based on both observational data (WSO magnetograms, MWO polar faculae counts and Pulkovo A ( t ) index) and outputs (polar cap magnetic flux and global dipole moment) of various existing flux transport dynamo models. We calculate Pearson correlation coefficients ( r ) of the predictors with the next cycle amplitude as a function of time measured from several solar cycle landmarks: setting r = 0 . 8 as a lower limit for acceptable predictions, we find that observations and models alike indicate that the earliest time when the polar predictor can be safely used is 4 years after polar field reversal. This is typically 2–3 years before solar minimum and about 7 years before the predicted maximum, considerably extending the usual temporal scope of the polar precursor method. Re-evaluating the predictors another 3 years later, at the time of solar minimum, further increases the correlation level to r & 0 . 9 . As an illustration of the result, we determine the predicted amplitude of Cycle 25 based on the value of the WSO polar field at the now official minimum date of December 2019 as 126 ± 3 . A forecast based on the value in early 2017, 4 years after polar reversal would have only differed from this final prediction by 3 . 1 ± 14 . 7 %.


In recent years, research has been conducted on the reflection of real space onto virtual objects. However, conventional methods have not been able to achieve accurate reflection due to problems such as the direction and angle of the reflected object not matching. In addition, since the light source is not estimated, the color of the virtual object floats away from the surroundings and shadows are not generated. In this study, we propose a method to integrate virtual objects and real space without any discomfort by using light source estimation.


This article provides a cross-case analysis of four art and design research centres operating within UK universities. Findings from autobiographical and semi-structured interviews with researchers, research managers, and research leaders indicate that they encounter similar issues in trying to establish internal legitimacy within the university alongside the need to gain external support and recognition. In dealing with these challenges, art and design research centres tend to pass through four broadly identifiable phases: (i) Origination (utilising credentials and leadership capacity), (ii) Establishment (securing resources and embedding dedicated systems and processes), (iii) Development (furthering profile, diversifying, and retaining autonomy), and (iv) Sustainability (enhancing research culture, networks, and influence).

Many interesting parallels are evident with the way small businesses strive to establish themselves within competitive market environments. Lessons for research managers and directors are explored to consider such similarities in key areas of responsibility that cover leadership, managing people and processes, developing organisational capacity, and building external networks. The research suggests research centre directors must demonstrate many intrapreneurial qualities to overcome obstacles in the development of a successful research team and that university departments can make substantial organisational interventions to help them succeed.


This study aims to explain the implementation of share waqf carried out at the Dompet Dhuafa institution, in addition to explaining the legal protection of the permanence of the object of share waqf in Law No. 41 of 2004 from the regulatory and technical aspects of the institution. This study uses a qualitative method by conducting an assessment of regulations, books, and contemporary fiqh books as a source of data in the preparation of writing this thesis. The results of the study show that in terms of regulation, Law Number 41 of 2004 concerning Waqf does not regulate the legal protection of the permanence of the waqf object. Meanwhile, in technical matters in Dompet Dhuafa, the institution in providing protection for the object of share waqf by managing it does not use the trading method, so that there is no capital loss


The purpose of this study was to investigate the usability of Moodle Learning Management System [LMS] as a web-support tool in teaching chemistry at second- ary school. For this purpose Moodle LMS was used as the web-support tool for teaching "Chemistry in Our Lives" unit in the 9th grade high school chemistry cur- riculum and the its effect on students' academic achievement and interest towards chemistry were investigated. The sample of the study was composed of total of 60 ninth grade students from two different classes in a high school in Erzurum. In this study in which instrumental case study was utilized as the research method, "Chem- istry in Our Lives" unit was taught through Context-based ARCS Instructional Model and Moodle LMS was used as the web-support tool. At the end of the im- plementation an achievement test was administered and semi-structured interviews with 13 students were done. The students' achievement test scores were compared with Kruskal-Wallis test according to the frequency of using Moodle LMS. Semi- structured interviews were subjected to descriptive analysis. The results showed that Moodle LMS which was used as a web-supported tool had positive effects on stu- dents' achievement and interest towards chemistry. In addition, the problems en- countered during Moodle LMS implementation have been identified and various suggestions have been made to overcome these problems.


The difference of constituents of whole plant as well as different parts of abrus cantoniensis and abrus mollis were studied by FTIR with secondary derivative spectra and semi-quantitative analysis.The volatile oil,triterpenes,flavonoids,saponin,polysaccharides were contained in A.cantoniensis and A.mollis,but the contents of flavonoids,saponin and polysaccharides of A.mollis were higher than A.cantoniensis.The characteristic spectra of IR fingerprint region of different parts in A.cantoniensis and A.mollis were as follows:flavonoids of stem were higher than root,but saponin and polysaccharides of root were all higher than stem in A.cantoniensis;the content of flavonoids,saponin and poly saccharide of leaf were highest,the flavonoids,saponin were lowest in root,while the content of polysaccharide were similar between root and stem in A.mollis.In hence,FTIR could be used to fast identify the difference of main chemical constituents between A.cantoniensis and A.mollis,and avoid evaluating the quality of medicinal material rely on single component.


Abstarct Lung cancer is the primary cause of tumor deaths for both sexes in most countries. Early diagnosis has an important prognostic value and has a huge impact on treatment planning Our approach is based on multiscale processing and artificial neural networks (ANNs). The problem of nodule detection is faced by using a two-stage architecture including: 1) an attention focusing subsystem that processes whole radiographs to locate possible nodular regions ensuring high sensitivity; 2) a validation subsystem that processes regions of interest to evaluate the likelihood of the presence of a nodule, so as to reduce false alarms and increase detection specificity. The proposed system's aim is to detect & classify lung cancer for early and effective treatment. In this work, we are proposing a computer aided diagnostic (CAD) system for automated classification of cancer stage. The ANN comprised three layers (one input layer, one hidden layer, and one output layer) Trained by back propagation. In proposed method back propagation feed forward neural network with Levenberg-Marquardt Algorithm may be used. Matlab based GUI is implemented. According to the parameters, Accuracy, Sensitivity, Specificity is calculated. According to the Experimental results 98% accuracy.


Globalization of the world economy enables companies and individuals to move across borders and seek new opportunities and business options in other countries. To do so persons may need to transfer residency or shift assets of permanent establishment. The adverse side of such a migration lies in the loss of tax revenues from taxation of capital gains that occur when shifted assets are sold in new country, frequently low-tax jurisdiction. Original home country can prevent loss of tax revenues from taxation of capital gain by imposition of an exit tax. Despite rationale of exit tax its impact in globalized world might be controversial, as it represents barrier to free movement of capital and persons and freedom of establishment, which was mirrored especially in a number of controversial decisions of the CJ EU. This paper investigates presence of the exit tax in the OECD and EU Member States and focuses on the most problematic provision – timing and possibility to defer payment of exit tax until the asset is sold which can soften adverse effect of exit tax on international movement of persons. This is subject of harmonisation of anti-tax-avoidance measures in the EU however the OECD anti- avoidance package (BEPS) does not include exit tax.

Individuals testing positive for anti-cyclic-citrullinated-peptide-antibodies (Anti-CCP) and musculoskeletal (MSK) complaints are at risk for developing rheumatoid arthritis (RA).We aim to identify factors involved in arthritis progression in a population considered at risk for RA.Anti-CCP-positive individuals with MSK complaints referred to rheumatologist in the Region Stockholm were recruited. Individuals lacked arthritis at clinical and ultrasound examination and were followed for ≥3 years or until arthritis diagnosis was made. Blood samples from inclusion were analyzed for 9 selected anti-citrullinated-protein-antibody (ACPA) reactivities (citrullinated α-1-enolase, fibrinogen, filaggrin, histone, vimentin and tenascin peptides); as well as a panel of 92 inflammation-associated proteins and HLA-SE alleles. Cox regression was applied to the data and a predictive multivariate model was identified. Results are shown with a confidence interval (CI) of 95 percent.267 individuals were recruited. 101 (38%) developed arthritis in median after 14 months (IQR: 6-27). In the multivariate analysis: ACPA reactivity (HR 8.0, CI 2.9-22, p<0.0001), IL15R-α levels (HR 0.6, CI 0.4-0.9, p 0.006), IL6 levels (HR 1.5, CI 1.2-1.8, p<0.0001) and the presence of tenosynovitis as detected by ultrasound (HR 3.4, CI 2.0-6.0, p<0.0001) were significantly associated with arthritis. Diagnostic accuracy for ACPA reactivity test had a sensitivity of 96% (CI 92-99.8), a specificity of 30% (CI 30-46), a positive predictive value of 51% (CI 43-58) and a negative predictive value of 94% (CI 87-99.7). Diagnostic accuracy for ultrasound assessed tenosynovitis had a sensitivity of 17% (CI 9-24), a specificity of 99% (CI 97-100), a positive predictive value of 89% (CI 74-100) and a negative predictive value of 64% (CI 57-70).We propose a high-risk RA phase characterized by the presence of certain ACPA reactivities, IL15-Rα, IL6, and tenosynovitis, parameters that could be used to identify individuals at particular low risk and high risk for arthritis progression.None.Alexandra Cîrciumaru: None declared, Yogan Kisten: None declared, Monika Hansson: None declared, Linda Mathsson-Alm Employee of: ThermoFisher Scientific, Vijay Joshua: None declared, Heidi Wähämaa: None declared, Malena Loberg Haarhaus: None declared, Joakim Lindqvist: None declared, Fei Guozhong: None declared, Nancy Vivar Pomiano: None declared, Hamed Rezaei: None declared, Erik af Klint: None declared, Aleksandra Antovic: None declared, Bence Réthi: None declared, Anca Catrina: None declared, Aase Hensvold: None declared.


ABSTRACT Production-type G-Vectoring Control vehicles are now being put on the market. Customers and reviewers have praised the handling quality and course traceability of these vehicles. This paper clarifies the mechanism behind this improvement in handling quality using a simple bicycle model and driver model analysis. It focuses on the residual yaw angular acceleration when the steering speed is zero and shows that GVC reduces its value. This result provides evidence for improved handling quality in GVC vehicles.


The study investigates the impact of domestic gold price on Indian stock market indices during the Pre and Post Global financial crisis era for the period from April 1999 to March 2013 using appropriate descriptive statistics and econometric analysis such as Augmented Dickey Fuller Unit Root Test and Linear Regression model. The domestic gold price in India is perpetually escalating in corollary of its passionate domestic demand on account of liquidity, protection and spreader portfolio. Indian households vacillate to consider the capital market as a viable asset class for parking their savings. When the stock market dishevels or when the dollar aggravates, gold protracts to act as a safe haven investment. Households persistently and predominantly invest in their quintessential favorite "Gold", which has the character of splendid at trouncing inflation. Rupee depreciation has caused gold prices in India to ascend appreciably and to hit high record. The study is based on secondary data obtained from World Gold Council database and NSE database. ADF Unit root test indicates that the selected time series are stationary at 1st difference. Linear Regression Methodology was employed to examine the impact of Domestic gold price on Indian Stock market indices during pre and post Global financial crisis era. More explicitly, the study concludes that the Global financial crisis has refocused investors' attention to safe haven assets such as gold and the equity markets have experienced hectic inconsistency. Domestic gold price continues to rule high. Gold effortlessly crushes most other investment options especially in equities in the aftermath Global Financial crisis.


A review of experimental data obtained recently on proton-radioactive nuclei is presented. The highlights include the observation of fine structure in proton emission, for the decays of 131 Eu, 145 Tm and 146 Tm, and the studies of the excited states in proton-emitting nuclei. The observation limits are extended to few nanobarns cross-sections C40 Ho, 164Ir and 130 Eu) and few microsecond half-lives (e.g., 145 Tm). Measured decay properties for thirty-nine proton-emitting ground and isomeric states contributed to the understanding of nuclear masses and evolution of single-particle states at and beyond the proton drip line. Experimental results have stimulated new theoretical approaches to proton emission and the structure of unbound narrow resonance states.

Abstract : This thesis effort modeled brigade-sized templates within the CAMEX model, and determined the effects of those templates on the direct fire attrition methodology. The model simulated combat between a U.S. brigade from a mechanized or armored division and a Soviet-style motorized rifle regiment. Three different scenarios were used to simulate combat between the forces. The scenarios included a movement to contact, an attack, and a deliberate defense. Each scenario was run using the battalion-sized templates and again with the brigade-sized templates. The results revealed that use of the model with brigade-sized templates will demonstrate similar results to those obtained using battalion-sized templates. The simulations also demonstrated a possible flaw in the representation of certain weapons systems such as the Bradley Fighting Vehicle. The use of brigade-sized templates shows promise as a way to decrease data entry requirements and speed scenario development. However, the gains are not without costs in terms of lost ability to replicate tactics at the battalion level.

The article deals with the problem of the water towers icing rate in winter seasons. The urgency of the problem is conditioned by the fact that the maintenance of rural water supply system in working condition at any season of the year and at any temperature fluctuations is a necessary part of the complex cycle of agricultural production. The scheme of heat loss compensation by the outside part of the water tower at the expense of radiogenic energy supply is submitted. The program algorithm for calculation the size of the underground part of water towers with the wind-energy unit has been suggested, due to which the heat transferred through the cylindrical wall and the heat flow from the ground to the underground water tank have been calculated.


Thirty-seven house finches (Carpodacus mexicanus) with conjunctivitis were admitted to a rehabilitation center. Six (35%) of 17 conjunctival swab samples collected before treatment began were positive on culture for Mycoplasma gallisepticum. All birds were treated with cipro f10xacin hydrochloride ophthalmic solution (one drop in each eye (OU) q 12h) for 5 to 7 days and tylosin tartrate in water (l mg/ml) as the sole source of drinking water for 21 to 77 days. Con junctivitis was resolved in all birds after therapy was completed (60 to 177 days). Conjunctival swab samples from all birds collected after treatment and submitted for culture were negative for M. gallisepticum. Two (11 %) of the 18 conjunctival swab samples collected after treatment were positive for M. gallisepticwn by polymerase chain reaction (PCR). Serum samples from 2 (5.4%) other of the 37 birds were antibody positive for M. gallisepticum by serum plate agglutination; serum samples from these two birds were antibody negative when retested 22 days later. No gross lesions were found at necropsy in 16 house finches that had been treated, including the birds that tested positive by PCR or serum plate agglutination. Tissue samples of conjunctiva, choanae, in fraorbital sinus, trachea, lungs, air sacs, and reproductive organs collected at necropsy were negative for mycoplasma by culture (n = 16) and PCR (n = 15). We did not tind evidence of M. gallisepticum infection in house finches after treatment with tylosin tartrate administered orally and ciprofloxacin hydrochloride ophthalmic solution applied topically.
