Measuring galaxy environment with the synergy of future photometric and spectroscopic surveys

We exploit the synergy between low-resolution spectroscopy and photometric redshifts to study environmental effects on galaxy evolution in slitless spectroscopic surveys from space. As a test case, we consider the future Euclid Deep survey (∼40 deg2), which combines a slitless spectroscopic survey limited at Hα flux ≥5 × 10−17 erg cm−2 s−1 and a photometric survey limited in H band (H ≤ 26). We use Euclid-like galaxy mock catalogues, in which we anchor the photometric redshifts to the 3D galaxy distribution of the available spectroscopic redshifts. We then estimate the local density contrast by counting objects in cylindrical cells with radius from 1 to 10 h−1Mpc, over the redshift range 0.9 < z < 1.8. We compare this density field with the one computed in a mock catalogue with the same depth as the Euclid Deep survey (H = 26) but without redshift measurement errors. We find that our method successfully separates high- from low-density environments (the last from the first quintile of the density distribution), with higher efficiency at low redshift and large cells: the fraction of low-density regions mistaken by high-density peaks is <1 per cent for all scales and redshifts explored, but for scales of 1 h−1Mpc for which is a few per cent. These results show that we can efficiently study environment in photometric samples if spectroscopic information is available for a smaller sample of objects that sparsely samples the same volume. We demonstrate that these studies are possible in the Euclid Deep survey, i.e. in a redshift range in which environmental effects are different from those observed in the local Universe, hence providing new constraints for galaxy evolution models.
Release of muscle α-actin into serum after intensive exercise

Purpose: To study the effects of high-level matches on serum alpha actin and other muscle damage markers in teams of rugby and handball players. Methods: Blood samples were drawn from 23 sportsmen: 13 rugby players and 10 handball players. One sample was drawn with the player at rest before the match and one immediately after the match. Immunoassays were used to determine troponin I, troponin T, LDH, and myoglobin concentrations. Western blot and densitometry were used to measure α-actin concentrations. Muscle injury was defined by a total CK value of > 500 IU/L (Rosalki method). Results: Mean preand post-match serum alpha-actin values were, respectively, 7.16 and 26.47 μg/ml in the handball group and 1.24 and 20.04 μg/ml in the rugby team. CPK, LDH and myoglobin but not troponin 1 levels also significantly differed between these time points. According to these results, large amounts of α-actin are released into peripheral blood immediately after intense physical effort. Possible cross-interference between skeletal and cardiac muscle damage can be discriminated by the combined use of α-actin and troponin I. Conclusion: The significant increase in alpha-actin after a high-level match may be a reliable marker for the early diagnosis and hence more effective treatment of muscle injury.
Properties of concrete with eggshell powder as cement replacement

This paper describes research into use of poultry waste in concrete through the development of concrete incorporating eggshell powder (ESP). Different ESP concretes were developed by replacing 5-15% of ESP for cement. The results indicated that ESP can successfully be used as partial replacement of cement in concrete production. The data presented cover strength development and transport properties. With respect to the results, at 5% ESP replacement the strengths were higher than control concrete and indicate that 5% ESP is an optimum content for maximum strength. In addition, the performance of ESP concretes was comparable up to 10% ESP replacement in terms of transport properties with control concrete. The results further show that addition of fly ash along with ESP is beneficial for improved performance of concretes.
Multiscale estimation of the field-aligned current density

Abstract. Field-aligned currents (FACs) in the magnetosphere–ionosphere (M–I) system exhibit a range of spatial and temporal scales that are linked to key dynamic coupling processes. To disentangle the scale dependence in magnetic field signatures of auroral FACs and to characterize their geometry and orientation, Bunescu et al. (2015) introduced the multiscale FAC analyzer framework based on minimum variance analysis (MVA) of magnetic time series segments. In the present report this approach is carried further to include in the analysis framework a FAC density scalogram, i.e., a multiscale representation of the FAC density time series. The new technique is validated and illustrated using synthetic data consisting of overlapping sheets of FACs at different scales. The method is applied to Swarm data showing both large-scale and quiet aurora as well as mesoscale FAC structures observed during more disturbed conditions. We show both planar and non-planar FAC structures as well as uniform and non-uniform FAC density structures. For both synthetic and Swarm data, the multiscale analysis is applied by two scale sampling schemes, namely the linear and logarithmic scanning of the FAC scale domain. The local FAC density is compared with the input FAC density for the synthetic data, whereas for the Swarm data we cross-check the results with well-established single- and dual-spacecraft techniques. All the multiscale information provides a new visualization tool for the complex FAC signatures that complements other FAC analysis tools.

Espaces, territoires et mégalithes : le plateau de Cauria (Sartène, Corse-du-Sud) au Néolithique et à l’Age du Bronze

Depuis 1994 et dans le cadre de deux PCR, la fouille de Renaghju a permis de reconnaitre l'existence de deux monuments de pierres dressees, edifies sur un emplacement deja occupe au Neolithique ancien. Le premier monument est date du milieu du V e millenaire, le second pourrait avoir ete edifie a la fin du Neolithique ou au debut de l'Age du Bronze. En considerant ces megalithes comme jouant un role social, une approche spatiale a ete mise en oeuvre dans la region du plateau de Cauria, espace qui recele un grand nombre de sites. Si les megalithes jouent entre autres le role de marqueurs de territoire, les sites d'implantations doivent refleter les motivations memes de ce choix. Pendant le Neolithique moyen, le premier monument de Renaghju s'inscrit dans un vaste territoire economique. Pendant l'Âge du Bronze, le deuxieme monument s'inscrit dans le meme espace alors morcele en plusieurs territoires dependants de sites perches et fortifies dans un contexte de competition accrue. Sur ces constats, on fonde l'hypothese selon laquelle le role des megalithes s'inscrit dans le fonctionnement meme de la societe dependant largement des potentiels des territoires et de leur capacite a entretenir l'existence des groupes. Ceux-ci doivent assurer leur cohesion interne afin d'inscrire dans la duree la maitrise des espaces et des ressources qui fondent leur permanence. Les references magico-religieuses sont ainsi rejetees au deuxieme plan, il s'agit bien d'un megalithisme des hommes et pour les hommes.
Space-Time Codes Technology

Space-time codes technology is a channel coding for wireless digital communications, where multiple antennas are employed. It improves the capacity of the transmission as well as reducing errors. Also, this technology does not require the expansion of bandwidth or time slots. In order to achieve the highest efficiency, we have to first investigate the maximum efficiency that can be achieved. Then, the code design criteria for obtaining the maximum efficiency have to be derived. Last, the code design approaches have to be proposed. The article discusses those procedures.
A 1-D Time-Dependent Model of a Hall Thruster with Side Walls

Abstract : Previous one-dimensional Hall thruster models predict some observed features correctly, but do not adequately treat the losses of energy and ionization to the side walls of the channel. Because those losses have important effects on the discharge dynamics and the thruster's efficiency and lifetime, their omission severely limits the utility of a model. The model reported here is obtained from a two- dimensional description by solving analytically for the radial variations of densities and velocities and then averaging over the radial coordinate in a way that retains the effects of the side walls. Our model also includes ion pressure, second ionization, a varying electron temperature, a diverging channel and a non-radial B field. It calculates the ion flux into the walls as well as the incident ion angles and energies as functions of axial position to predict the profile of erosion of the walls by sputtering. The collision and ionization rates are all treated as functions of the electron temperature. The derivation of the equations is explained and typical results of numerical solutions are presented.
Organizational tenure and mastery-avoidance goals: the moderating role of psychological empowerment

Mastery-avoidance (MAv) goals are recognized to be detrimental as they arouse counterproductive work-related behaviors. In the current literature, MAv goals are assumed to be more predominant among newcomers and longer-tenured employees. The alleged relationship provides important implications but yet has received scant empirical attention. In response, this study examines the proposed U-shaped curvilinear relationship between organizational tenure and MAv goal orientation. In addition, the potential moderating role of psychological empowerment on this curvilinear relationship is investigated. Based on data from 655 certified accountants, the results support the existence of the hypothesized curvilinear relationship. Also, it revealed that for employees who experience higher levels of psychological empowerment, the U-shaped relationship between organizational tenure and MAv goal orientation becomes flattened. Implications and future research are discussed.
The Efficacy of the Random Walk Hypothesis in the Nigerian Stock Exchange Market

The Efficient Market Hypothesis (EMH) has been a subject of considerable debates in developed economies; for some time now. The debate has been carried into the emerging market. This study contributes to existing evidence on the efficiency of emerging stock markets using data from the Nigerian Stock Exchange (NSE). Quantitative research method was adopted by conducting Normality test, Runs test and modified version of Augmented Dickey-Fuller unit root tests to examine whether stock price changes in the Nigerian stock exchange market were random. Findings from the study reveal that changes in stock price were random. Overall result from the empirical analysis suggests that the Nigerian stock exchange is efficient in the weak form. Keywords: Efficient Market Hypothesis (EMH), Random Walk Theory, Normality and Runs Tests, Nigerian Stock Exchange (NSE), Weak form Efficient.

To obtain the dissipation function, an approximate expression for the velocity potential calculated previously authors up to order β3 has been used. Here β = b̄/d is a small dimensionless parameter, b̄ is the mean bubble radius and d is the mean distance between bubbles.  2004 Elsevier SAS. All rights reserved.
Acute Psychosis and Takayasu Vasculitis

Takayasu arteritis is one of the large vessel vasculitis with variable clinical features in Indian patients. It is common in males and may be associated with tuberculosis and often presents with large vessel wall inflammation, obstruction and aneurysm. A 23-year-old female presented with features of acute psychosis and during evaluation and following electroconvulsive therapy she was found to be tachycardic and pulse less in one arm. Further CT angiogram proved features of aortoarteritis with raised inflammatory markers and her infective screen including TB came back as negative. She was treated with steroids, losartan and corticosteroids and Methotrexate was added as steroid sparing immune suppression. She remains disease free and doing well. Literature review suggests increasing incidence of this vasculitis and early effective treatment helps to reduce morbidity and prolong disease free remission.
Perceptions of Factors Affecting Milk Quality and Safety Among Large and Small Scale Dairy Farmers in Zimbabwe

The study investigated the perceptions of milk producers on milk quality and safety. Randomly selected large-scale farmers ( ) and small-scale farmers ( ) were surveyed using semistructured questionnaires. An ordinal logistic regression was used to estimate the probability of farmers considering milk quality and safety important. Large-scale farmers were 3 times more likely to consider that breed affects milk quality compared to their small-scale counterparts. Farmers aged over 30 years were 3 times more likely to indicate that hygiene affected milk quality. The likelihood of milk transportation affecting its quality was 4 times higher in small-scale farmers compared to large-scale producers. Postmilking contamination of milk was perceived to occur during transportation by small-scale farmers, whilst commercial farmers ranked storage as the important source of contamination after milking. Udder diseases were ranked first by large-scale farmers while small-scale farmers ranked milking environment as the major cause of milk spoilage. The likelihood of milk safety being important was two times higher in large farms compared to small-scale farms. Intervention programmes on milk safety should mainly target small-scale dairy farmers since they are less concerned about milk quality and safety.
Reflections on the causes and treatment of multiple sclerosis Rozważania na temat przyczyn powstawania stwardnienia rozsianego i leczenia

Sclerosis multiplex (SM) is considered as a immunologic disease, which pathogenesis still remains unknown — it is therefore difficult to choose the optimal method of treatment. The aim of this review is to analyze the vascular theory of pathogenesis of SM and possibilities of new therapeutic options of the disease. Surprising is the number of common elements both in the vascular theory of SM, and the effects of subarachnoid haemorrhage. Additionally, in light of current research studies, it apears that responsible for the neurological detoriation after SAH is not just reactive arterial narrowing, but rather the local inflammatory response generated by the extravasated blood. It seems to be a logical proposal to use the similar treatment in the acute MS relapse as the nimodipine treatment for acute neurological deterioration after SAH.
Hardiness, Sensation Seeking, Optimism and Social Support as Predictors of Stress Tolerance among Private Secondary Schools Teachers in Lagos State

This study investigated the extent to which hardiness, sensation seeking, optimism and social support predicts stress tolerance among private secondary school teachers in Lagos State, Nigeria. Using an ex post-facto design, 272 teachers (123 males; 149 females) were selected from 8 privates secondary schools in Lagos State. Their ages ranged from 21 to 58 years with a mean age of 37.57 years (SD=11.29). The study instruments contain short hardiness scale, sensation seeking scale, optimism scale, social support scale and stress tolerance scale. Six hypotheses were generated and tested using Pearson Product Moment Correlation and Hierarchical Multiple Regression Analysis. The result showed that hardiness significantly predicted stress tolerance among private secondary school teachers (β=-0.24; t=-5.90; p<0.01). Sensation seeking significantly predicted stress tolerance among private secondary school teachers (β=0.18; t=3.88; p<0.01). Also, optimism significantly predicted stress tolerance among private secondary school teachers (β=-0.18; t=-3.72; p<0.01). Similarly social support had a positive relationship with stress tolerance among private secondary school teachers (r=(270) =. 562; p<0.01). However, educational qualification significantly predicted stress tolerance among private secondary school teachers (β=0.27; t=-3.85; p<0.01). Finally, the multiple regression analysis also indicated that hardiness, sensation seeking, optimism, and social support jointly predicts stress tolerance among private secondary school teachers [F(1,268)=27.25; p<0.01]. Thus, it is recommended that management should employ more qualified teachers and provide conductive work environment for their employees.
THE MAGELLANIC STREAM AND DEBRIS CLOUDS

We present a study of the discrete clouds and filaments in the Magellanic Stream using a new high-resolution survey of neutral hydrogen (H i) conducted with the H75 array of the Australia Telescope Compact Array, complemented by single-dish data from the Parkes Galactic All-Sky Survey. From the individual and combined data sets, we have compiled a catalog of 251 clouds and listed their basic parameters, including a morphological description useful for identifying cloud interactions. We find an unexpectedly large number of head–tail clouds in the region. The implication for the formation mechanism and evolution is discussed. The filaments appear to originate entirely from the Small Magellanic Cloud and extend into the northern end of the Magellanic Bridge.
ANALYSIS OF THE PRESENCE OF EPSTEIN-BARR VIRUS IN HODGKIN'S LYMPHOMA IN IRANIAN CHILDREN BY EBER IN SITU HYBRIDIZATION

Introduction: Epstein-Barr virus is a tumorigenic herpes virus which belongs to DNA viruses, infects, and persists in B-lymphocytes of most human beings. This virus is associated with some cases of Hodgkin’s lymphoma. The aim of the present study was to investigate the presence of Epstein-Barr virus in Hodgkin’s lymphoma in children. Materials & Methods: In this study, 16 formalin-fixed paraffin embedded blocks of Hodgkin’s lymphoma tissue samples were collected from the archives of the Pathology Department of Fasa University of Medical Sciences. The presence of RNA transcripts encoded by the virus was examined with the EBERs in situ hybridization method. Results: The 16 formalin-fixed paraffin-embedded samples belonged to patients with Hodgkin’s lymphoma with the mean age of 8 years (range: 4 to 12 years). They were investigated using the EBERs in situ hybridization method. In 12 specimens (75%), including 9 male and 3 female samples, the EpsteinBarr virus was present in different subtypes of Hodgkin’s lymphoma. Eighty percent of mixed cellularity, 67% of nodular sclerosis and 100% of lymphocyte predominance subtypes proved positive. The presence of the Epstein-Barr virus in the age groups of 4-7 and 8-12 years was 71.5% and 77.8%, respectively. Conclusion: The results of the present study indicate a strong relationship between the Epstein-Barr virus and Hodgkin’s lymphoma in children. The relationship between the Epstein-Barr virus and Hodgkin’s lymphoma in Iranian children follows a pattern similar to that of other developing countries.
Genetic Variation in Young Fraser Fir Progeny Tests

Fraser fir (Abies fraseri [Pursh] Poir.) is found naturally in only a few stands at high elevations in North Carolina, Virginia, and Tennessee. These forests are associated with important scenic and recreational areas such as the Great Smoky Mountains National Park, Mount Mitchell State Park, the Balsam Mountains, and the Mount Rogers National Recreation Area (Dull et al. 1988). In addition to its recreational and ecological importance, Fraser fir also holds great economic importance as a Christmas tree species. It is grown in plantations as Christmas trees throughout the southern Appalachians as well as other areas of the United States.
Ofloxacin Ocular Inserts: Design, Formulation and Evaluation

In developing a drug delivery strategy, issues of absorption, distribution, metabolism, and elimination must be considered. The eye presents unique opportunities and challenges when it comes to the delivery of pharmaceuticals. While absorption by this route is bungling, there are few side effects with conventional ocular dosage forms. Hence, ocular inserts were prepared with prolonged release of drug and minimum swelling within cul-de-sac using ofloxacin as a model drug; Hydroxy propyl methyl cellulose, Methyl cellulose, Poly vinyl pyrrolidone and Poly vinyl alcohol as polymers. PEG-400 was incorporated as plasticizer. The main purpose of the study is to deliver the drug in zero order kinetics. Methods: Solvent casting technique was followed to prepare ofloxacin ocular films. Eight formulations were formulated and subjected to various physicochemical evaluations. Ocular inserts prepared were smooth and passed all the evaluation tests performed. Formulation OF2 shows a maximum cumulative percentage drug release of 91.27 % at the end of 24 hours. Ocuserts formulated also passed the test for sterility. They showed zero-order release of the drug in the in vitro and in vivo release studies. The drug in the films was found to be active against selected microorganisms as was proved by microbial efficacy studies. A high correlation coefficient was found between in vitro and in vivo release rate studies. Shelf-life of the product was found to be more than one year. The results of in vitro, in vivo, kinetic treatment (zero order and Korsemeyer's regression values) and rate constant 'k' value suggest that OF2 was the best formulation among the formulations studied for formulating ofloxacin ocular insert.
