Shadow images of Kerr-like wormholes

Investigations of shadows of astrophysical entities constitute a major source of insight into the evolution of compact objects. Such effects depend on the nature of the compact object and arise on account of the strong gravitational lensing that casts a shadow on the bright background. We consider the Kerr-like wormhole spacetime (Bueno et al 2018 Phys. Rev. D 97 024040), which is a modification of the Kerr black hole that degenerates into wormholes for nonzero values of the deviation parameter . The results suggest that the Kerr spacetime can reproduce far away from the throat of the wormhole. We obtain the shapes of the shadow for the Kerr-like wormholes and discuss the effect of the spin a, the inclination angle , and the deviation parameter on the size and nature of the shadow. As a consequence, it is discovered that the shadow is distorted due to the spin as well as the deviation parameter and the radius of the shadow decreases with if the ADM mass of the Kerr-like wormholes is considered.

Reproductive Performance of Dairy Buffaloes Supplemented with Varying Levels of Vitamin E

The effect of vitamin E supplementation on plasma α-tocopherol level, total antioxidant level and reproductive performance in Murrah buffaloes was studied during periparturient period. Twenty-four advance pregnant buffaloes were randomly divided into four equal groups as T1, T2, T3 and T4 and were supplemented with 0, 1,000, 1,500 and 2,000 IU of α-tocopheryl acetate (Merck) from 60 days prepartum to 30 days postpartum and 0, 500, 750 and 1,000 IU from 30 to 60 days postpartum, respectively. Blood samples were collected at -60, -45, -30, -15, -7, 0, 7, 15, 30 and 60 days of parturition and were analyzed for plasma α-tocopherol and total antioxidant activity (TAA). The intake of DM, CP and TDN did not vary among different groups. Plasma α-tocopherol and TAA around parturition (-7 to 15 day) in T3 and T4 were significantly higher than the control group. There was 17% reduction in retention of fetal membranes (RFM) and metritis in T4 than control. The post partum estrus interval averaged 58.00, 55.33, 51.83 and 43.00 days in T1, T2, T3 and T4 respectively. There was significant reduction in days open in both T3 and T4 in comparison to T1 group (127,130 Vs.146). All the vitamin E supplemented groups showed reduction in days open than their previous lactation performance. Supplementation of vitamin E at 1,500 IU d -1 from 60 day prepartum to 30 day post partum to buffaloes exhibited beneficial effect on plasma α-tocopherol level and TAA around parturition and continuation of its supplementation at 1,000 IU d -1 from 30 to 60 days of lactation improved post partum reproductive performance of buffaloes.

Business cycle synchronization of a small open EU-candidate country’s economy with the EU economy

The objectives of this paper are to empirically identify business cycles in a small open EU-candidate country such as the Republic of Macedonia and to assess the degree of synchronization of the country’s business cycle with the cycle of the EU economy. Towards the first objective, we apply linear and nonlinear methods for delineating the production gap cycle in the Macedonian economy. As for the second objective, we apply autoregressive methods to assess the size and speed of cyclical adjustment of the Macedonian economy to output shocks to the Euro-zone economy. The results of our analysis suggest a high degree of synchronization of the Macedonian business cycles with the cycles of the EU economy. Also, the shocks in economic activity in the Euro-zone economy are transmitted almost instantaneously, and with a large magnitude, to the Macedonian economy. Finally, the impact of the Euro-zone output contraction is less pronounced than the impact of the Euro-zone output expansion, suggesting an impact of the country’s autonomous countercyclical economic policies. Key words: Business cycles, Exogenous shocks, Potential output, Filter methods, Asymmetric adjustment.JEL: E32, F41, F62, C13, C22. Sinhronizacija poslovnog ciklusa ekonomije male otvorene zemlje kandidata za Evropsku uniju sa ekonomijom Evropske unije Cilj rada je da se empirijski identifikuju poslovni ciklusi u maloj otvorenoj zemlji kandidatkinji EU kao sto je Republika Makedonija kao i procena stepena sinhronizacije poslovnog ciklusa zemlje sa ciklusom ekonomije EU. Prema prvom cilju, primenjujemo linearne i nelinearne metode za određivanje ciklusa proizvodnog jaza u Makedonskoj ekonomiji. Sto se tice drugog cilja, primjenjujemo autoregresivne metode za procenu velicine i brzine ciklicnog prilagođavanja Makedonske ekonomije na sokove proizvodnje u ekonomiji eurozone. Rezultati nase analize ukazuju na visok stepen sinhronizacije Makedonskih poslovnih ciklusa sa ciklusima ekonomije EU. Takođe, sokovi u privrednim aktivnostima u ekonomiji evrozone prenose se skoro trenutacno i u velikoj meri na Makedonsku ekonomiju. Na kraju, uticaj smanjenja proizvodnje u evrozoni je manje izražen nego uticaj ekspanzije proizvodnje u evrozoni, sto ukazuje na uticaj autonomnih kontraciklicnih ekonomskih politika u zemlji. Kljucne reci: Poslovni ciklusi, egzogeni sokovi, potencijalna proizvodnja, metode filtriranja, asimetricno podesavanje.
Revision of the Alpheus formosus Gibbes, 1850 complex, with redescription of A. formosus and description of a new species from the tropical western Atlantic (Crustacea: Decapoda: Alpheidae)

The Alpheus formosus Gibbes, 1850 complex is revised based on materials from the eastern Pacific and western Atlantic. Three species are recognized: Alpheus panamensis Kingsley, 1878 in the eastern Pacific, ranging from the Gulf of California to the Galapagos Archipelago; A. formosus Gibbes, 1850 (synonym: A. poeyi Guérin Méneville, 1857) in the western Atlantic, ranging from North Carolina and throughout the Caribbean to southern Brazil; and A. paraformosus n. sp. , presently known only from the southwestern Caribbean (Panama) in the western Atlantic. Alpheus paraformosus n. sp. differs from A. formosus and A. panamensis by the distinctly shorter rostral furrows, the absence of balaeniceps setae on the fingers of the minor chela, and also several subtle but discrete features in the color pattern. Alpheus formosus is redescribed based on recently collected material. A female specimen from Florida Keys is designated as neotype of A. formosus. Morphology, color and genetics all suggest that A. formosus and A. panamensis are transisthmian sister species, with A. paraformosus n. sp. being their nearest relative.
A Pyrolytic, Carbon‐Stabilized, Nanoporous Pd Film for Wide‐Range H2 Sensing

With the increasing relevance of H2 gas in modern industry, high-performance H2 sensors (sensors that exhibit, e.g., a fast response, good stability, sensitivity, etc.) are becoming increasingly important in detecting and monitoring H2. Because of its noteworthy ability to absorb a large quantity of H2 and its highly selective response to H2, Pd has found wide applicability in various H2 sensors including Pd-film-based resistive sensors, metal oxide semiconductor-type sensors, Schottkydiode-type sensors, and optical sensors. Among these H2 sensors, resistive sensors based on dense Pd films have attracted much attention because of their simple device structure and fabrication process. However, several drawbacks, including a narrow detection range (dense-film resistive sensors are only sensitive to medium-level concentrations of H2 gas), a slow response time, and instability in higher concentrations of H2 usually hinder the widespread applicability of resistive sensors based on dense films. To improve H2-sensing performance, nanostructured Pd materials have been developed, and they have demonstrated a much quicker response to H2 gas. Break-junctioned Pd nanowires reported by Favier et al. have shown the fastest response because of a volume-expansion-induced resistance decrease upon the absorption of H2. [8] However, these Pd nanowires are only sensitive to high concentrations of H2. Based on the same sensing mechanism, Xu et al. have used self-assembled monolayers to promote the formation of break-junctioned Pd nanoclusters to realize a fast H2 response. Recently, we have fabricated nanoporous Pd film sensors by using anodic aluminum oxide (AAO) as a substrate. It was shown that the nanoporous Pd film demonstrated an increased resistance upon absorption of H2. The nanoporous Pd sensor had a quick response to low concentrations of H2 gas (less than 1 % H2). For higher H2 concentrations, the nanoporous Pd films directly supported by AAOs lost their sensing stability because of stress-induced blistering of the film. Here, we report a simple but effective method to fabricate a nanoporous Pd film sensor that has a remarkable sensing performance and is able to detect both dilute and high concentrations of H2 gas (ranging from 250 ppm to 10 % H2) with quick response times at room temperature, through the use of pyrolytic carbon as a transition layer between the Pd film and the AAO template/substrate. A mechanism based on nanoporous structure-enhanced H2 sensing is proposed. Briefly, an aluminum film deposited onto a highly doped n-type Si wafer was anodized in 0.3 M oxalic acid to obtain the AAO template. A film of amorphous carbon only several nanometers thick was deposited onto the AAO template by using the chemical vapor deposition (CVD) pyrolysis of acetylene. Detailed information about the anodization and CVD processes can be found elsewhere. A Pd film was then deposited, via sputtering, onto the upper surface of the carbon-coated AAO substrate. A resistive sensor based on a Pd film was then fabricated and tested under various concentrations of H2 in nitrogen (Fig. 1).
CHILE'S STRUCTURAL ADJUSTMENT: RELEVANT POLICY LESSONS FOR LATIN AMERICA

This 'aper presents an overview of the Chilean adjustment experience of the past two decades. After reviewing the main policy issues during the period, the paper submits a discussion about the different phases that characterized the application of key economic reforms in the areas of macroeconomic management, market deregulation, trade opening and the financial and social sectors. The paper discusses the sequencing of policy measures and the likely implications of the chilean experience for other Latin American countries in need of structural adjustment. The paper argues that the adjustment process envisaged by most developing countries is necessarily lengthy, given that two successive phases should he typically distinguished --corresponding to stabilization and structural adjustment-characterized by different emphasis in terms of macro and microeconomic policies. The paper also argues that appropriate labor market policies should be adopted early in the process, to facilitate the industrial restructuring and diminish the unemployment impact. Also, it indicates that proactive and reactive social policies are essential ingredients to smooth the transition and attaining the political sustainahility required for any reform package.

Application of Biometrics in Mobile Voting

Voting process in today's era is behind its time in respect of the usage of modern ICT. The voting process is being seen mostly as a manual and paper based one. This process can be overwhelming, time-consuming and prone to security breaches and electoral fraud. Over the years technology related systems were being developed to resolve some of the issues like electoral fraud, impersonation, double voting etc. One such system is Electronic based voting that has been actively used for voting in countries like India. However, these systems seem to be prone to electoral frauds and voters have to make tremendous effort to cast their ballots. There are still a few very important areas which have to be identified and addressed viz., the Security which involves a person be able to vote in a secure manner, the time spent for voting by voters, the efficiency in counting of votes and the cost involved in employing people towards monitoring the voting process. So taking these areas/issues into consideration we have now come with the biometrics authenticated mobile voting system, to start with for a country like Jamaica. The technology being proposed now is novel and the first of its kind proposed at present. It is proposed that using fingerprint supported biometric control information and encryption along with Secure Socket Layer i.e. SSL using VeriSign, would make the software involved in the voting process well secured. In addition tying the credentials to a mobile device will make the system even more robust. We have considered the mobile equipment for the present system development, a smart phone using Android 3.0 (Honeycomb). The details of the proposed development are presented in this paper.
Earth in Mind: On Education, Environment, and the Human Prospect

Review: Earth in Mind: On Education, Environment and the Human Prospect By David W. Orr Reviewed by Sandra Meredith Centre for Research in Innovation Management Orr, David W. EARTH IN MIND: ON EDUCATION, ENVIRONMENT AND THE HUMAN PROSPECT, Washington DC. : Island Press 1994. 213 pp. US $16.95 Paper ISBN: 1-55963-259-X. Recycled, acid-free paper. Just as I was struggling to write a conference paper on the subject of the greening of higher education, attempting to strike a radical note, EARTH IN MIND: ON EDUCATION, ENVIRONMENT AND THE HUMAN PROSPECT appeared on my desk. I had already established a link between education and the future of the global environment, but I was having difficulty finding language strong enough to describe the radical changes I think are necessary in today's learning systems. Fortunately, David Orr's book struck fearlessly at the core of the issues and supplied me with the language I needed. The first part of EARTH IN MIND assumes an ecological perspective and challenges the conventional wisdom that all education is good. Each piece in this set of essays highlights different aspects of education. The first question posed is 'what is education for'? Orr sees it as no guarantee of decency, prudence, or wisdom (8), dispelling the myth that with enough knowledge and technology, we can 'manage planet earth. ' Recognizing that higher education has sought to extend human domination of the natural world is the first step to changing its direction. According to Orr, it is better to reshape ourselves to fit a finite planet than to attempt to reshape the planet to fit our infinite wants (9). Orr's comparison of 'formal education' to the notion of 'calling' in the example of Albert Speer and Aldo Leopold underscores the dangers inherent in certain educational systems. Speer's apolitical education, unlinked to values, direction, or a questioning of the order of things, left him defenseless against Nazi propaganda. In contrast, Leopold's scientific education, founded on his calling to appreciate nature and a profound values system, provided him with a purposeful, productive career.
runmixregls: A Program to Run the MIXREGLS Mixed-Effects Location Scale Software from within Stata

Hedeker and Nordgren (2013) present the stand-alone MIXREGLS program for fitting the mixed-effects location scale model to continuous longitudinal and other clustered data. This model can be used when interest lies in joint modeling the mean and dispersion of subjects' responses over time. The model extends the standard two-level randomintercept mixed model by allowing both the within- and between-subject variances to be influenced by the covariates and for the within-subject variance to additionally depend on a subject random-scale effect. In this article we present the runmixregls command to run MIXREGLS seamlessly from within Stata. We illustrate the notable advantages of using runmixregls by replicating and extending the two example analyses presented in Hedeker and Nordgren (2013). We then use runmixregls to demonstrate a new and important research finding. Namely, that ignoring the random-scale effect in the withinsubject variance function will lead to the regression coefficients in this function to be estimated with spurious precision, especially the regression coefficients of subject-level covariates.
A 45° saw-dicing process applied to a glass substrate for wafer-level optical splitter fabrication for optical coherence tomography

This paper reports on the development of a technology for the wafer-level fabrication of an optical Michelson interferometer, which is an essential component in a micro opto-electromechanical system (MOEMS) for a miniaturized optical coherence tomography (OCT) system. The MOEMS consists on a titanium dioxide/silicon dioxide dielectric beam splitter and chromium/gold micro-mirrors. These optical components are deposited on 45° tilted surfaces to allow the horizontal/vertical separation of the incident beam in the final micro-integrated system. The fabrication process consists of 45° saw dicing of a glass substrate and the subsequent deposition of dielectric multilayers and metal layers. The 45° saw dicing is fully characterized in this paper, which also includes an analysis of the roughness. The optimum process results in surfaces with a roughness of 19.76 nm (rms). The actual saw dicing process for a high-quality final surface results as a compromise between the dicing blade’s grit size (#1200) and the cutting speed (0.3 mm s−1). The proposed wafer-level fabrication allows rapid and low-cost processing, high compactness and the possibility of wafer-level alignment/assembly with other optical micro components for OCT integrated imaging.
Electron Stimulated Molecular Desorption of a NEG St 707 at Room Temperature

Electron stimulated molecular desorption (ESD) from a NEG St 707r (SAES Getters ) sample after conditioning and after saturation with isotopic carbon monoxide 2 , CO , has been studied on a laboratory setup. Measurements were performed using an electron beam of 300 eV kinetic energy, with an average electron intensity of 1.6 10 electrons s . The electrons were impinging on the 15 cm target surface at perpendicular incidence. It is found that the desorption yields (molecules/electron) of the characteristic gases in an UHV system (hydrogen, methane, water, carbon monoxide, carbon dioxide) for a fully activated NEG as well as for a NEG fully saturated with CO are lower than for OFHC copper baked at 120 C. A small fraction only of the gas which is required to saturate the getter surface can be re-desorbed and thus appears to be accessible to ESD.
Improving Recommender Systems Using Knowledge Obsolescence as a Predictor of Trust

In the current context of the Social Web, trust has emerged as a concept and mechanism to differentiate users of this Social Web and the content they generate. Much effort has been devoted to study trust predictors with the aim to provide some operational use of the concept. We propose in this work a new predictor for trust: knowledge obsolescence. We provide a characterization of the concept and a description of the relation between trust and knowledge obsolescence. We applied the concept to a generic recommender system. For this purpose, we have developed a software simulator that allow us to test trust and knowledge obsolescence networks in the recommender systems context. Interesting results were obtained. We found that recommender systems success is augmented. Moreover, we found an improvement in some cases for the coverage of potential recommendable items. We did not find statistical significant benefit on the quality of recommendations.
Continuance of Social Network Services Games

By using Social Network Services (SNSs) as platforms, game developers have gathered a huge user base. These games provide has further enlarged the SNS user base. However, there are signs that this symbiotic growth is slowing down. We developed a model and tested 14 hypotheses. Our main findings are: Although SNSs are “social,” “social norms” do not have much impact on the intention to use the games continually. Although users generally are not addicted to SNS games, the creation of addiction is an effective way to achieve continuance.

Using scripts and stories: illustrating the influences on drama performance assessment

Abstract The dramatic arts utilise emotion, introspection, artistry and interpretation from multiple perspectives to promote dialogue and reflection. Drama research can access these kinds of engagements by using artistic mediums to present phenomena, experiences and findings. This paper resulted from a research project investigating drama performance assessment in Australian schools. Data was collected in Year 11 and 12 Drama classes at six school sites, using ethnographical observation of performances, narrative and semi-structured interviews, and participant observation. Findings of the research indicate that there are several influences on students’ performative responses for assessment, including the local curriculum and assessment practices, school and class cultures and the approach of the teacher. These influences are illustrated using mediums that complement the field of drama, specifically scripts and stories. This paper presents three of these artefacts; one collection of storied descriptions and two scripts, discussing the methodology used to create them and exploring future directions for the presentation of findings, using other mediums that complement the field of drama.
