Facebook support groups for ovarian cancer carers: a qualitative evaluation

A cancer diagnosis takes a great toll on the health of both patients and their carers. Online cancer support groups, including cancer support Facebook groups, have evolved as new sources of support for cancer patients and their carers. However, little is known about how cancer carers make use of such online resources. Most research attention has been paid to Facebook support groups for cancer patients. This research is designed to determine the content of communication in Ovarian Facebook pages, and the impact of those communications on carers of ovarian cancer patients. The study will contribute to knowledge about how cancer patients’ carers use Facebook cancer support groups and the impact of this use on their health and quality of life.

Homology classes which are represented by graph links

We give a necessary and sufficient condition for a one-dimensional homology class of a graph manifold to be represented by a graph link. The purpose of this paper is to give a necessary and sufficient condition for a one-dimensional homology class of a graph manifold to be represented by a graph link. For this, we define the Jaco-Shalen-Johannson complex of a graph manifold (? 1), using the so-called torus decomposition theorem due to Jaco-Shalen and Johannson (see also Waldhausen [2]), and the main result is stated as follows (? 2): THEOREM. Let M be a graph manifold prime to S1 X S2 and p: M -T WM the natural map to the Jaco-Shalen-Johannson complex of M. Then an element a of H1(M; Z) can be represented by a graph link if and only if p*o(a) = 0 in Hl(WM; Z). If the ambient manifold M is not prime to S1 X S2, the homotopy class of the map p: M -T WM is not unique in general, and this makes the statement complicated (? 3). The proof of these results is based on the study of global graph links in [3]. 1. Preliminaries. Throughout this paper, manifolds are compact, oriented, of dimension three and with toral boundary, and links are oriented. A manifold M is a graph manifold if there is a family of disjointly embedded tori in M such that each connected component of the manifold obtained by cutting M along these tori is the total space of an S1-bundle over a surface. A link is called a graph link if its exterior is a graph manifold. We say that a manifold is prime to S1 X S2 if its prime decomposition does not contain S1 X S2. See Jaco [1] and Yano [3] for other terminology. To state our result, we need the following theorem due to Jaco-Shalen and Johannson (see Jaco [1] and also Waldhausen [2]). THEOREM 1.1 (JACO SHALEN, JOHANNSON). Let M be a Haken manifold which is either closed or with incompressible boundary. Then there exists a unique Seifert submanifold E c M up to ambient isotopy such that (1) E is maximal, and (2) if E' is a Seifert manifold pair distinct from (S3, 0), (S2 X SI, 0), (D2 X I, aD 2 X I) or (S1 X D2, 0), then every nondegenerate map f: E' -> (M, aM) is homotopic to fo such that fo(E') c E. The E above is called the characteristic Seifert manifold of M. Received by the editors September 19, 1983 and, in revised form, March 14, 1984. 1980 Mathematics Subject Classification.

Primary Structure of a (cid:103) Subunit of G Protein, (cid:103) 12 , and Its Phosphorylation by Protein Kinase C*

We have determined the primary structure of a novel (cid:103) subunit ( (cid:103) 12 , previously designated (cid:103) S1 ) of G protein purified from bovine spleen. The mature (cid:103) 12 protein composed of 68 amino acids had acetylated serine at the N terminus and geranylgeranylated/carboxylmethyl-ated cysteine at the C terminus. This was consistent with the C-terminal prenylation signal in the amino acid sequence, which was predicted from (cid:103) 12 cDNA isolated from a bovine spleen cDNA library. Western blots with the specific antibody against (cid:103) 12 showed that (cid:103) 12 is pres- ent in all tissues examined. Among various (cid:103) subunits ( (cid:103) 1 , (cid:103) 2 , (cid:103) 3 , (cid:103) 7 , and (cid:103) 12 ), (cid:103) 12 has a unique property to be phosphorylated by protein kinase C. The phosphorylated amino acid residue was Ser 1 (or Ser 2 ). The phosphorylated the (cid:98)(cid:103) 12 -effector interaction. Comparison of amino acid sequences of various isoforms of (cid:103) revealed diverged residues concentrated at the N-terminal region, which seems to participate in individual functions of (cid:98)(cid:103) complexes. The experimental evidence that the N-terminal 15 residues of (cid:103) subunits specifies the interaction with G (cid:97) s (33) is in line with the regulatory role of the extreme N-terminal phosphorylation of (cid:103) 12 in the (cid:97) - (cid:98)(cid:103)

Sequencing a whole genome, cataloguing full-length cDNAs and ESTs, and construction of a comprehensive mutant population are essential steps in genome projects of individual model species. Tomato is one of the most important model crops to be undertaken for study over the next few decades, and the Solanaceae Genomics Project (SOL) has begun genome projects as international collaborations. The Solanum lycopersicum cultivar Micro-Tom shares several advantages with Arabidopsis, including its small size, short life cycle (approximately 90 days), and growth normally under artificial light. Here we demonstrate an initial attempt to generate a comprehensive mutant population in Micro-Tom. A total of 3,839 M2 families derived from ethylmethanesulfonate (EMS) mutagenesis were visually phenotyped, and putative mutants were classified into 15 primary and 48 secondary categories based on the SOL database, “The Genes That Make Tomatoes”.
Eigenvector Error Bound and Perturbation for Polynomial and Rational Eigenvalue Problems

A computed approximate eigenpair (λ̂∗, x̂) of a polynomial eigenvalue problem P (λ)x = 0 is usually considered acceptable if the normalized residual P (λ̂∗)x̂ is small, as it indicates the computed solution has a small backward error. The error in the approximate eigenvalue λ̂∗ can be bounded for example as the error of λ̂∗ as an eigenvalue of a linearization of P . However, no previous result exists that rigorously bound the error in the computed eigenvector x̂. We derive a posteriori upper bounds for the angle between x̂ and an exact eigenvector x of P (λ) by showing that the desired angle ∠(x̂, x) is bounded by ∠(ŷ, y), where y is an exact eigenvectors of a linearization and ŷ is its approximation, constructed using x̂ and λ̂∗. The result extends to other nonlinear eigenvalue problems such as rational matrix eigenproblems, and the bounds can be obtained not only from linearizations but also from other formulations such as quadratifications and `-ifications. This work shows that just like for linear eigenvalue problems, the eigenvector error is proportional to the residual and inversely proportional to the separation between the eigenvalues of P (λ). One implication of our result is that an eigenvector can be computed accurately even when it corresponds to several distinct eigenvalues.
Convergence of AI, IoT, Big Data and Blockchain: A Review

Data is the lifeblood of any business. Today, big data has applications in just about every industry – retail, healthcare, financial services, government, agriculture, customer service among others. Any organization that can assimilate data to answer nagging questions about their operations can benefit from big data. In overall, the demand for big data transcend across all sectors and business. Those who work to understand their customers’ business and their problems will be able to proactively identify big data solutions appropriate to their needs, and thus gain competitive advantage over their competitors. Job demand for people with big data skill-set is also in the rise especially professional, scientific and technical services; information technology; manufacturing; and finance and insurance; and retail. DevOps is baseless without the cloud. IoT needs cloud to operate efficiently, for computing is required by the cloud operate efficiently. AI remained only as model up until the advent of big data. Blockchain and related distributed ledger technologies are disrupting the technology sector as we know it. The confluence of technologies is just inevitable and often they are beneficial especially today when usher in the 4th industrial revolution (Rabah, 2017a) and the forth coming machine economy (Rabah, 2018). More-so, data is a key ingredient of approaches to developing AI and machine learning, which are now being applied to a wide variety of uses, from stock trading to chatbots to self-driving cars. There is barely a business or human activity today that is not considered as a target for AI in future years and decades.
Depth wise Distribution of Heavy Metals in Different Soil Series of Northwestern India

Soil serves as a sink for some noxious elements known as heavy metals i.e. lead, chromium, cadmium, cobalt and nickel where they persist in soil for long period of times, caused detrimental effects on health and quality of agricultural soils and crops (Nicholsona et al., 2003). Due to anthropogenic activities, they add harmful and toxic metals in soil which indirectly affects on human‟s health through food chain (Simeonov et al., 2003). The upper 25cm surface layer of soil is mostly affected by the toxic metals where the roots of the plants or crops located (Freitas et al., 2004). The anthropogenic activities which contribute pollution to water bodies are industrial and International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 8 Number 02 (2019) Journal homepage: http://www.ijcmas. com
RSA algorithm of EON based on coloring theory

—Traditional wavelength division multiplexing networks use fixed grids to meet the needs of today's rapidly evolving networks. The elastic optical network with OFDM as the core can divide the spectrum resources into finer granularity, thereby improving the utilization of network resources and reducing the bandwidth blocking rate in the network. this paper considers risk avoidance to improve the elastic optical network routing and wavelength assignment algorithm based on spectrum coloring theory: First, define the network The routing risk coefficient, starting from the power communication service flow, analyzes the resource status of nodes and links, and establishes a route optimization model. Secondly, based on the characteristics of power communication network, based on the graph coloring theory and considering the spectrum fragmentation problem, the risk equilibrium model is designed. Finally, the joint transfer hops and the network risk value are jointly balanced, and a mixed integer linear programming model of the RSA problem with the minimum transfer hop and the lowest risk balance is jointly established. The spectrum is based on the coloring number. Equally divided blocks, the spectrum is allocated by block. The simulation results show that compared with the typical algorithm, the proposed algorithm alleviates the problem of uneven distribution of risk and spectrum fragmentation in the power communication network in the prior art, and comprehensively considers routing and spectrum, and balances the number of hops. Balance the risk with the effect of improving resource utilization.
Effects of B 2 O 3 and TiO 2 on crystallization behavior of some slags in Al 2 O 3-CaO-MgO-Na 2 OSiO 2 system

Nowadays, there are increasing demands for developing mould fluxes without fluoride due to environmental concerns. Slag bearing titanium oxide and/or boron oxide proved to be promising substitute for traditional mould fluxes with fluoride. In the present work, Crystallization behaviors of some slags in Al2O3-CaO-MgO-Na2O-SiO2-B2O3-TiO2 system were investigated using Single Hot Thermocouple Technique (SHTT), Differential Thermal Analaysis (DTA) and X-ray diffraction (XRD) techniques. It was found that the liquidus temperature of slag decreases with increases of B2O3 content. The XRD analysis on the crystallized samples shows that crystallization products are perovskite, gehlenite and wollastonite. TimeTemperatureTransformation diagrams (TTT) for various slags have been constructed using SHTT technique. It was found that B2O3 can significantly increase the incubation time for crystallization of slags. The incubation time for crystallization of slags decreases with increase of titanium oxide content from 5% to 10%. The morphology of crystals was also investigated using SHTT technique. At higher temperature, dendrites and columnar crystal tend to form and grow with time progress, while at lower temperature, small crystals appear and the amount of crystal increase with time increasing.
Media, Politics and Democracy: A Critical Perspective

This article, mostly through a theoretical background, focuses on general debates of democracy, media and politics. Giving insights regarding overall perspectives of democracy, media-democracy and politics relationship, the study tries to demonstrate the view of this interaction and how media should function in a democratic development. At the end, again to have a clearer point of view, this article tackles construction of the news stories as being matter of structuring agendabuilding, public opinion and political perspectives through the news media. Here particularly media and democracy relationship will be tried to be examined giving the importance of the media courses for democracy to function in a proper way. While examining the press and politics linkage as being the main actors to set up the daily agenda and a social consensus; the role of the media in shaping the public opinion and the ideology both through external or/and internal (institutional) motives have been tried to be discussed to better debate the media problems and examine their relationship with the politics especially in Turkey.
CONCENTRATION OF MEASURE INEQUALITIES FOR MARKOV CHAINS AND -MIXING PROCESSES By Paul-Marie Samson

We prove concentration inequalities for some classes of Markov chains and -mixing processes, with constants independent of the size of the sample, that extend the inequalities for product measures of Talagrand. The method is based on information inequalities put forward by Marton in case of contracting Markov chains. Using a simple duality argument on entropy, our results also include the family of logarithmic Sobolev inequalities for convex functions. Applications to bounds on supremum of dependent empirical processes complete this work.
Texture and Mechanical Behavior of Magnesium During Free-End Torsion

Torsion experiments were carried out on pure magnesium (99.9%) and the magnesium alloy AZ71 under free-end conditions of testing. The alloy had an axisymmetric initial texture, while the pure Mg samples were prepared from a rolled plate with a nonaxisym-metric initial texture. The torque as a function of the twist angle was measured at different temperatures (room temperature, 150°C, and 250°C). During twisting, systematic shortening of the samples was observed (Swift effect). The evolution of the crystallographic texture was analyzed by electron backscattering diffraction measurements. The occurrence of dynamic recrystallization (DRX) was detected in pure Mg at 250° C. The Swift effect in the axisymmetric samples was simulated with the "equilibrium equation" approach using polycrystal modeling. In the nonaxisymmetric samples, the texture was simulated at different angular positions with the help of the viscoplastic self-consistent model. The changes in the textures due to DRX were explained in terms of the Taylor factor. Finally, the texture evolution was interpreted with the help of the behavior of ideal orientations and persistence characteristics of hexagonal crystals in simple shear.
Evaluation of the bond strength at the resin-dentin interface using self-etching adhesive systems containing different functional monomers

Background: Self-etching adhesive systems have attracted considerable interest in dentistry, as these materials simplify the restorative protocol and allow a less sensitive adhesive technique. The objective of the present study was to analyze in vitro the performance of self-etching adhesive systems containing different functional monomers. Materials and Methods: The adhesives evaluated were: Clearfil SE Bond (CSE) adhesive containing 10-MDP, Optibond All-in-One (OPT) containing GPDM, Palfique Bond (PB) containing 3D-SR monomer. Immediate microtensite bond strength (TBS) and after thermocycling were realized. Interaction between the functional monomers and dentin was characterized using thin-film X-ray diffraction (TF-XRD) and scanning electron microscopy (SEM). In the experiments were used 60 molars. Thirty molars were divided into 3 experimental conditions (n=10) according to the adhesive system; the teeth were restored and sectioned on “toothpick” specimens for TBS. Additionally, five teeth were prepared in the form of discs and the adhesives applied without light curing on the surface for XRD analysis. For morphological evaluation in SEM, 25 teeth were treated with the respective adhesives. The TBS data were submitted to ANOVA two factors and Tukey's test (5%). Results: The adhesive vs. time interaction was statistically significant (p<0.001), with the CSE adhesive obtaining the highest means and being the worst performance of BP. The analysis of XRD found that the monomers interact chemically with hydroxyapatite, but with different intensities. SEM images indicate that the applied adhesives infiltrate the dentin forming resin tags in greater or lesser amounts. Conclusions: The different functional monomers have a direct impact on the effectiveness of the adhesive bond, with the 10-MDP monomer, the CSE adhesive, highlighted by the higher TBS values. The self-etching adhesive systems allow a simplification in the restorative protocol, besides a less sensitive adhesive technique and less clinical time for the procedure. Therefore, knowing its mechanical and chemical properties is important to ensure longer-lasting restorations.
Prolactin down-regulates CD4 CD25CD127 regulatory T cell function in humans

Among its many functions, prolactin (PRL) participates in immune responses and promotes the activation, differentiation and proliferation of T cells. However, the mechanisms by which PRL regulates regulatory T (Treg) cells are still unknown. Our goal was to determine whether PRL plays a role in Treg function. We measured the expression of PRL and its receptor in Treg and effector T (Teff) cells from 15 healthy individuals. We also evaluated the functional activity of Treg cells by examining proliferation and cytokine secretion in cells activated with anti-CD3/CD28 in the presence or absence of PRL. We report that Treg cells constitutively expressed PRL receptor, whereas Teff cells required stimulation with antiCD3/CD28 to induce PRL receptor expression. Expression of PRL was constitutive in both populations. We found that the addition of PRL inhibited the suppressor effect (proliferation) mediated by Treg cells in vitro, reducing suppression from 37.4 to 13% when PRL was added to co-cultures of Treg and Teff cells (P! 0.05). Cultures treated with PRL favoured a Th1 cytokine profile, with increased production of TNF and IFNg. We report for the first time that PRL receptor expression was constitutive in Treg cells but not in Teff cells, which require stimulation to induce PRL receptor expression. PRL inhibited the suppressive function of Treg cells, apparently through the induced secretion of Th1 cytokines. Journal of Molecular Endocrinology (2012) 48, 77–85
On the Jacobian of the Klein curve

Its is known that the Jacobian J of the Klein curve is isogenous to E3 for a certain elliptic curve E. We compute explicit equations for E and prove that J is in fact isomorphic to E3. We also identify the subgroup of J generated by the image of the Weierstrass points of the curve under an Albanese embedding, and we show that it is isomorphic to Z/2Z x (Z/7Z)3.
Superconductivity in the Presence of Strong Pauli Paramagnetism: CeCu_{2}Si_{2}

after annealing to 20 K, lnRT ' ' was found. These films did not exhibit superconductivity as measured resistively down to the lowest temperatures attainable (T1.5 K). The above-described behavior suggests that the Hg-Xe system exhibits a metal-nonmetal transition which occurs with a dependence on concentration and with a critical concentration close to that of continuous percolation in 3D. Beyond the percolation threshold, the systems acquire a negative TCR but are still superconductors. With further increase in Xe concentration, a regime in which the conductivity is dominated by hopping is entered. The approach to an insulating configuration beyond the percolation threshold is probably the Mott-Anderson transition of Refs. 2-4 and is accompanied by the eventual disappearance of superconductivity as determined resistively. The authors would like to thank R. Mikkelson for many helpful discussions. This work was supported by the U. S. Department of Energy under Contract No. EY-V6-S-02-1569-A002.
Reactive power compensation in a three-phase power supply system in an electric vehicle charging station

The article presents the problem of reactive power compensation in an electric network, which powers a charging station for electric vehicles. The reactive power is present because the converters have a reactance character. Mobile inverters are single-phase receivers, so they cause a lack of symmetry in a three-phase system. Lack of symmetry causes an unbalance component to appear. The power compensation discussed here results in an improvement in the power factor. The reduction of the reactive and unbalance power is the result of this compensation. The article takes into account a non-sinusoidal method of power supply.
