Contratualismo, Utilitarismo e o Modelo do Estado Mercantilista vs Patrimonialismo e Patriarcalismo: sobre o Desenvolvimento da Inglaterra e dos Estados Unidos e o Atraso do Brasil no Século XIX
Authors: Chiappin José Raymundo Novaes , Leister Carolina
Published: April 2018

O artigo discute as causas do desenvolvimento econômico da Inglaterra e dos Estados Unidos e do atraso brasileiro no século XIX. O quadro teórico faz uso dos programas contratualista e utilitarista, com o modelo de Hobbes de um Estado mercantilista como uma máquina corporativa, com governo representativo, para alinhar o interesse privado com o público, evitando que o primeiro se aproprie do segundo e voltado para a construção da nação-Estado pela aplicação da ciência e tecnologia na produção e distribuição. Modelo vocacionado a evitar o governo dos homens e induzir a industrialização. Se esse Estado é a principal causa do desenvolvimento da Inglaterra e dos Estados Unidos, então sua ausência pode ajudar a explicar o atraso brasileiro. Faz-se uma introdução crítica, por um lado, às propostas de Faoro e de Buarque de Holanda, e, por outro, à de Zanella, Ekelund e Laband, como insuficientes para explicar a causa do atraso brasileiro, assim como à concepção de mercantilismo por eles utilizada.

Authors: ALBAK Emre İsa , SOLMAZ Erol , KAYA Necmettin , ÖZTÜRK Ferruh
Published: April 2018

The impact attenuator is a safety component which is used to reduce the effects of frontal crash on driver, which can cause injuries. This article describes the design process of the impact attenuator with lightweight materials to satisfy the required weight reduction targets for Formula SAE racing car. This study is carried out as part of weight reduction studies on Formula SAE racing car. As a first step, the impact-absorbing structures and technical features were compared. In this step, it was decided to use EPP foam material with a density of 100 g/l as basic material to design a lightweight impact attenuator. Also, the design outlines of shape and analysis techniques for impact attenuator was defined in this step. Then, validation process was carried out for virtual model of 100 g/l EPP foam material. Foam material model was validated using referencestudy in literature. After model validation, a new impact attenuator was designed according to Formula SAE rules. It is 10% lighter than the standard model. The results show that selected EPP foam material can be used to design a lightweight impact attenuator for formula SAE race car to satisfy weight reduction requirements successfully.
THE EFFECT OF SODIUM CARBONATE ON ELEVATED TEMPERATURE RESISTANCE OF CEMENT MORTARS CONTAINING NATURAL ZEOLITE
Authors: BİLİM Cahit
Published: April 2018

In this paper, the effect of sodium carbonate (Na2CO3) on the flexural and compressive strength of cement mortars containing natural zeolite subjected to high temperatures were examined. The results obtained from the tests were compared with the reference mortars. In the mortar mixtures, sand and water quantities were kept constant. Water/binder and sand/binder ratios were 0.5 and 3.0, respectively. In the mixtures, the crushed sand was used and ordinary Portland cement (OPC) was replaced with 5, 10, 15 and 20% natural zeolite by weight. For activation of zeolite, sodium carbonate having 7% Na dosage was used as an activator. The findings showed that the resistance of mortars subjected to high temperatures were dependent on the temperature level, and that the fire resistance of zeolite mortars was higher than that of mortar made with OPC only. Additionally, it was seen from the test results that Na2CO3 used for activation in zeolite mortars led to a decrease in the flexural and compressive strength values after the high temperatures.

EXPERIMENTAL INVESTIGATION OF FLOW STRUCTURE DOWNSTREAM OF PERMEABLE CYLINDERS
Authors: Şanlı Bengi , Akıllı Hüseyin
Published: April 2018

Flow
structure downstream of permeable cylinders was investigated using high-image
density Particle Image Velocimetry technique in deep water. The free stream
velocity is U∞= 156 mm/s, which corresponds to the Reynolds number
of Re=6250 based on the cylinder diameter D=37.5 mm. To reveal the effect of
the porosity, four different porosities (β= 0.4, 0.5, 0.6 and 0.7) were used.
This study showed that the usage of permeable cylinder decreases the occurrence
of large-scale vortical structures downstream of the bluff body. As the
porosity increases, turbulent kinetic energy, Reynolds shear stress and
intensity of turbulences decrease as a sign of attenuated fluctuations in the
wake region. For the permeable cylinders having the porosity higher than 0.6,
the flow behaves as there is no object in flow.
APPLICATION OF HOMOTOPY PERTURBATION METHOD TO HEAT TRANSFER IN NANOFLUIDS
Authors: Oahimire Jonathan , Adeokun Olusegun
Published: April 2018

This paper investigates heat transfer in a nanofluid using the Homotopy Perturbation method. Similarity transformation variables and a stream function are used to transform the partial differential equations governing the fluid flow into ordinary differential equations. He’s Homotopy perturbation method is then used to solve the resulting dimensionless equations. It was discovered that an increase in the fraction number, magnetic parameter or Grashof number led to a corresponding increase in the rate of heat transfer regardless of the nanoparticles in the fluid. These results are in agreement with those found in existing literature.
Structure, Electronic And Vibrational Study of 7-Methyl-2,3-Dihydro-(1,3)Thiazolo(3,2-A) Pyrimidin-5-One by Using Density Functional Theory
Authors: Joshi Bhawani Datt , Khadka Janga Bahadur , Bhatt Atamram
Published: April 2018

We have presented molecular structure and vibrational wavenumber assignments of 7-methyl-2,3-dihydro-(1,3)thiazolo(3,2-a)pyrimidin-5-one. Both ab initio Hartree-Fock and density functional theory employing 6-311++G(d,p) basis set have been used for the calculations. The scaled values of the calculated vibrational frequencies were used for assignments on the basis of potential energy distribution. The structure-activity relation has been interpreted by mapping molecular electrostatic potential surface. Electronic properties have been analyzed by using time dependent density functional theory (TD-DFT) for both gaseous and solvent phase. The calculated HOMO (highest occupied molecular orbital) and LUMO (lowest unoccupied molecular orbital) energy values show that the charge transfer occurs within the molecule. Journal of Institute of Science and TechnologyVolume 22, Issue 2, January 2018, Page: 1-11

White clover plant, Trifolium repens L. one of the important forage crop, entirely depends on insects for its pollination. The research aims to study diversity and relative abundance of insect visitors of white clover and their relation with environmental variables in open ground of Bhaktapur Multiple Campus. Quadrate sampling method was used to explore diversity of insect visitors. Observations of the insects were conducted at morning (09:00 AM to 10:00 AM), noon (12:00 PM to 01:00 PM) and afternoon (3 PM to 4 PM) each day during study period. There were 3472 individuals of insect collected that belong to 20 species in three orders: Hymenoptera (69%), Lepidoptera (27%) and Diptera (4%). Number of individuals of visitors were comparatively higher at noon (1426) than in morning (1256) and lower in afternoon (790 individuals). Number of species found in morning and noon were same (20 species) whereas number of species found in evening was less (16 species). Apis cerana and Lampides boeticus are the most dominant species belonging to orders Hymenoptera and Lepidoptera respectively. The relation of diversity with environmental variables was correlated by using Multivariate analysis test. The test showed significant effect of light intensity, humidity, temperature and the latter one was the most influential factor on the composition of species. Journal of Institute of Science and TechnologyVolume 22, Issue 2, January 2018 Page: 86-91
Preparation and Characterization of Activated Carbon from Waste Sawdust from Saw Mill
Authors: Shrestha Dibyashree , Gyawali Gobinda , Rajbhandari Armila
Published: April 2018

Activated carbon was prepared in laboratory using waste sawdust powder of Shorea robusta (Sal) from saw mill by chemically activated Na2CO3 followed by carbonization technique. Thus prepared activated carbon was characterized by Iodine Number (IN) and Methylene Blue Number (MBN). Iodine number was found to be 534.6 mg/g whereas MBN was found to be 196.08 mg/g which indicated the presence of micropores as well as mesopores in the prepared material. This was also exposed by SEM image. Specific surface area was measured by BET method and was found to be 10.01 m2/g. Then phase state of samples was determined by X-ray diffraction (XRD), which indicated the amorphous nature of the prepared material. The development of surface functionality due to activation was examined by Fourier Transform Infrared Spectroscopy (FTIR) which showed the presence of oxygenated functional groups such as ether, diketone, lactone, phenol on the material. These functional groups are considered to be electrochemically active and contribute to the capacitance of electrical double layer capacitance (EDLC). Further, electrochemical characterization of prepared material was carried out by conductivity test and cyclic voltammetry. The cyclic voltametric curve showed symmetric rectangular shape indicating electrical double layer capacitive behavior. Journal of Institute of Science and TechnologyVolume 22, Issue 2, January 2018, Page: 103-108

Authors: Bhattarai Bishnu Prasad , Kindlmann Pavel
Published: April 2018

We investigated the factors affecting group sizes and population composition of chital (Axis axis), sambar (Rusa unicolor), hog deer (Axis porcinus), northern red muntjac (Muntiacus vaginalis), wild boar (Sus scrofa) and gaur (Bos gaurus) in the Chitwan National Park in southern Nepal. The study revealed that mean group sizes were the largest for chital (winter: 13.76 and summer: 11.01), followed by wild boar (winter: 6.89 and summer: 8.51), hog deer (winter: 5.52 and summer: 6.66), gaur (winter: 4.36 and summer: 5.81), sambar (winter: 1.86 and summer: 2.45) and muntjac (winter: 1.44 and summer: 1.46). The age and sex ratio of ungulates were biased towards females in all species. This study found the highest proportion of young individuals in wild boar and the lowest in gaur. Habitat structure, presence of predators and human disturbances strongly affected group size of ungulates in this area. Larger groups of ungulates were found in less disturbed open areas with high predatory pressure, while smaller groups and solitary individuals were found in highly disturbed forest areas. We recommend that management of human disturbances inside the park and regular monitoring of the changes in the demography of ungulate populations will improve long-term conservation strategies in this park. Journal of Institute of Science and TechnologyVolume 22, Issue 2, January 2018, Page: 156-167

Published: April 2018

The study was conducted to assess the impacts of trout farming on water quality using macro invertebrates as bio-indicators. Two trout farms were selected for the study, viz., Gandaki Trout Farm (GTF) in Kaski district and Fall & Trout Fish Farm (FTF) in Nuwakot district. Reference and impacted sites were selected in each trout farms from where macro invertebrates were collected and physico-chemical parameters were measured. Sorensen’s Index and Multiple Site Similarity Index were calculated to compare the macro-invertebrate assemblages between the impact and the reference sites. Water quality classes were also calculated using macro invertebrate-based tool, NEPBIOS/ASPT scores. Altogether 24 families of macro invertebrates were observed at GTF and 12 families at FTF. The Sorensen’s Similarity Index was greater than 0.5 between reference and impacted sites at GTF; whereas it was only 0.28 at FTF indicating comparatively low level of similarity. In addition, Multiple Site Similarity Index (0.64) at GTF also indicated high similarity between the macro invertebrate assemblages. Reference sites showed higher scores with higher diversity of macro invertebrates. Both farms had suitable water quality for trout (dissolved oxygen and temperature) and most of the physico-chemical parameters did not show significant differences except pH and turbidity at GTF probably due to small scale operation and production. Journal of Institute of Science and TechnologyVolume 22, Issue 2, January 2018, Page: 175-182

Published: April 2018

The article analyzes the issues concerning customer satisfaction survey with the complexity of handling refrigerated containers at the seaports' container terminals. It aims to determine the criteria to evaluate the port comprehensive service and to examine the opinion of chosen seaports terminals on customer satisfaction with the complexity of handling refrigerated containers. Evaluation criteria of comprehensive service of refrigerated containers in seaports were identified and examined. The analysis of ports opinions on customer satisfaction with the service of refrigerated containers was based on surveys, which covered 5 container terminals located in the Polish cities of Gdansk, Gdynia and Szczecin. The research revealed that according to the ports, complex service primarily affects the high-level customer satisfaction and shorter service time, while implementation of this service regards a good level of customer service and price.
Marginalised voices in the inclusive recruitment discourse: a dilemma of inclusion/exclusion in the (Swedish) police
Authors: Wieslander Malin
Published: April 2018

Recruitment for diversity is part of a range of proactive strategies for overcoming occupational stereotyping in a number of professions, as well as addressing a history of discrimination against women and minority groups. One such campaign launched by the Swedish police involves ‘inclusive recruitment’. By analysing the discourse of inclusive recruitment and its subject positions in police student talk, this article shows how borders between people who are assigned different social categories are constructed, challenged and reinforced. Positive intentions in agendas towards diversity are problematised when minorities are ascribed as admitted on quotation, which places them in a ubordinate and ‘risky position’ within an occupation and on less legitimate premises. A dilemma emerges between a call to represent minority groups and the risk of categorising them as ‘others’. In particular, voices of resistance from ethnic minority police women show how practices of exclusion could jeopardise efforts to achieve inclusion.

Chlorination of phenylallene derivatives with 1-chloro-1,2-benziodoxol-3-one: synthesis of vicinal-dichlorides and chlorodienes
Authors: Zhao Zhensheng , Murphy Graham K
Published: April 2018

Allyl and vinyl chlorides represent important structural motifs in organic chemistry. Herein is described the chemoselective and regioselective reaction of aryl- and α-substituted phenylallenes with the hypervalent iodine (HVI) reagent 1-chloro-1,2-benziodoxol-3-one. The reaction typically results in vicinal dichlorides, except with proton-containing α-alkyl substituents, which instead give chlorinated dienes as the major product. Experimental evidence suggests that a radical mechanism is involved.
Integration of Massage Therapy in Outpatient Cancer Care
Authors: Cowen, PhD, LMT Virginia S. , Tafuto, MLS Barbara
Published: April 2018

Background: Massage therapy can be helpful in alleviating cancer-related symptoms and cancer treatment-related symptoms. While surveys have noted that cancer patients seek out massage as a nonpharmacologic approach during cancer treatment, little is known about the integration of massage in outpatient cancer care.Purpose: The purpose of this study was to examine the extent to which massage is being integrated into outpatient cancer care at NCI-designated Cancer Centers.Setting: This study used descriptive methods to analyze the integration of massage in NCI-designated Cancer Centers providing clinical services to patients (n = 62).Design: Data were collected from 91.1% of the centers (n = 59) using content analysis and a telephone survey. A dataset was developed and coded for analysis.Main Outcome Measure: The integration of massage was assessed by an algorithm that was developed from a set of five variables: 1) acceptance of treatment as therapeutic, 2) institution offers treatment to patients, 3) clinical practice guidelines in place, 4) use of evidence-based resources to inform treatment, and 5) shared knowledge about treatment among health care team. All centers were scored against all five variables using a six-point scale, with all variables rated equally.Results: The integration of massage ranged from not at all (0) to very high (5) with all five levels of integration evident. Only 11 centers (17.7% of total) rated a very high level of integration; nearly one-third of the centers (n = 22) were found to have no integration of massage at all—not even provision of information about massage to patients through the center website.Conclusions: The findings of this analysis suggest that research on massage is not being leveraged to integrate massage into outpatient cancer care.
A Serendipitous MWA Search for Narrowband Signals from ‘Oumuamua

We examine data from the Murchison Widefield Array (MWA) in the frequency range 72–102 MHz for a field of view that serendipitously contained the interstellar object ‘Oumuamua on 2017 November 28. Observations took place with a time resolution of 0.5 s and a frequency resolution of 10 kHz. Based on the interesting but highly unlikely suggestion that ‘Oumuamua is an interstellar spacecraft, due to some unusual orbital and morphological characteristics, we examine our data for signals that might indicate the presence of intelligent life associated with ‘Oumuamua. We searched our radio data for (1) impulsive narrowband signals, (2) persistent narrowband signals, and (3) impulsive broadband signals. We found no such signals with nonterrestrial origins and make estimates of the upper limits on equivalent isotropic radiated power (EIRP) for these three cases of approximately 7 kW, 840 W, and 100 kW, respectively. These transmitter powers are well within the capabilities of human technologies, and are therefore plausible for alien civilizations. While the chances of positive detection in any given search for extraterrestrial intelligence (SETI) experiment are vanishingly small, the characteristics of new generation telescopes such as the MWA (and, in the future, the Square Kilometre Array) make certain classes of SETI experiments easy, or even a trivial by-product of astrophysical observations. This means that the future costs of SETI experiments are very low, allowing large target lists to partially balance the low probability of a positive detection.
Elevation or Suppression? The Resolved Star Formation Main Sequence of Galaxies with Two Different Assembly Modes
Authors: Liu Qing , Wang Enci , Lin Zesen , Gao Yulong , Liu Haiyang , Teklu Berzaf Berhane , Kong Xu
Published: April 2018

We investigate the spatially resolved star formation main sequence in star-forming galaxies using Integral Field Spectroscopic observations from the Mapping Nearby Galaxies at the Apache Point Observatory survey. We demonstrate that the correlation between the stellar mass surface density (Σ*) and star formation rate surface density (ΣSFR) holds down to the sub-galactic scale, leading to the sub-galactic main sequence (SGMS). By dividing galaxies into two populations based on their recent mass assembly modes, we find the resolved main sequence in galaxies with the “outside-in” mode is steeper than that in galaxies with the “inside-out” mode. This is also confirmed on a galaxy-by-galaxy level, where we find the distributions of SGMS slopes for individual galaxies are clearly separated for the two populations. When normalizing and stacking the SGMS of individual galaxies on one panel for the two populations, we find that the inner regions of galaxies with the “inside-out” mode statistically exhibit a suppression in star formation, with a less significant trend in the outer regions of galaxies with the “outside-in” mode. In contrast, the inner regions of galaxies with “outside-in” mode and the outer regions of galaxies with “inside-out” mode follow a slightly sublinear scaling relation with a slope ∼0.9, which is in good agreement with previous findings, suggesting that they are experiencing a universal regulation without influences of additional physical processes.
Dissolved Massive Metal-rich Globular Clusters Can Cause the Range of UV Upturn Strengths Found among Early-type Galaxies
Authors: Goudfrooij Paul
Published: April 2018

I discuss a scenario in which the ultraviolet (UV) upturn of giant early-type galaxies (ETGs) is primarily due to helium-rich stellar populations that formed in massive metal-rich globular clusters (GCs), which subsequently dissolved in the strong tidal field in the central regions of the massive host galaxy. These massive GCs are assumed to show UV upturns similar to those observed recently in M87, the central giant elliptical galaxy in the Virgo cluster of galaxies. Data taken from the literature reveal a strong correlation between the strength of the UV upturn and the specific frequency of metal-rich GCs in ETGs. Adopting a Schechter function parameterization of GC mass functions, simulations of long-term dynamical evolution of GC systems show that the observed correlation between UV upturn strength and GC specific frequency can be explained by variations in the characteristic truncation mass

such that

increases with ETG luminosity in a way that is consistent with observed GC luminosity functions in ETGs. These findings suggest that the nature of the UV upturn in ETGs and the variation of its strength among ETGs are causally related to that of helium-rich populations in massive GCs, rather than intrinsic properties of field stars in massive galactic spheroids. With this in mind, I predict that future studies will find that [N/Fe] decreases with increasing galactocentric radius in massive ETGs, and that such gradients have the largest amplitudes in ETGs with the strongest UV upturns.

Detailed chemical abundance distributions for 14 elements are derived for eight high-probability stellar members of the solar metallicity old open cluster M67 with an age of ∼4 Gyr. The eight stars consist of four pairs, with each pair occupying a distinct phase of stellar evolution: two G dwarfs, two turnoff stars, two G subgiants, and two red clump (RC) K giants. The abundance analysis uses near-IR high-resolution spectra (λ1.5–1.7 μm) from the Apache Point Observatory Galactic Evolution Experiment survey and derives abundances for C, N, O, Na, Mg, Al, Si, K, Ca, Ti, V, Cr, Mn, and Fe. Our derived stellar parameters and metallicity for 2M08510076+1153115 suggest that this star is a solar twin, exhibiting abundance differences relative to the Sun of ≤0.04 dex for all elements. Chemical homogeneity is found within each class of stars (∼0.02 dex), while significant abundance variations (∼0.05–0.20 dex) are found across the different evolutionary phases; the turnoff stars typically have the lowest abundances, while the RCs tend to have the largest. Non-LTE corrections to the LTE-derived abundances are unlikely to explain the differences. A detailed comparison of the derived Fe, Mg, Si, and Ca abundances with recently published surface abundances from stellar models that include chemical diffusion provides a good match between the observed and predicted abundances as a function of stellar mass. Such agreement would indicate the detection of chemical diffusion processes in the stellar members of M67.

We present the Kepler Object of Interest (KOI) catalog of transiting exoplanets based on searching 4 yr of Kepler time series photometry (Data Release 25, Q1–Q17). The catalog contains 8054 KOIs, of which 4034 are planet candidates with periods between 0.25 and 632 days. Of these candidates, 219 are new, including two in multiplanet systems (KOI-82.06 and KOI-2926.05) and 10 high-reliability, terrestrial-size, habitable zone candidates. This catalog was created using a tool called the Robovetter, which automatically vets the DR25 threshold crossing events (TCEs). The Robovetter also vetted simulated data sets and measured how well it was able to separate TCEs caused by noise from those caused by low signal-to-noise transits. We discuss the Robovetter and the metrics it uses to sort TCEs. For orbital periods less than 100 days the Robovetter completeness (the fraction of simulated transits that are determined to be planet candidates) across all observed stars is greater than 85%. For the same period range, the catalog reliability (the fraction of candidates that are not due to instrumental or stellar noise) is greater than 98%. However, for low signal-to-noise candidates between 200 and 500 days around FGK-dwarf stars, the Robovetter is 76.7% complete and the catalog is 50.5% reliable. The KOI catalog, the transit fits, and all of the simulated data used to characterize this catalog are available at the NASA Exoplanet Archive.

We present high-precision timing data over time spans of up to 11 years for 45 millisecond pulsars observed as part of the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) project, aimed at detecting and characterizing low-frequency gravitational waves. The pulsars were observed with the Arecibo Observatory and/or the Green Bank Telescope at frequencies ranging from 327 MHz to 2.3 GHz. Most pulsars were observed with approximately monthly cadence, and six high-timing-precision pulsars were observed weekly. All were observed at widely separated frequencies at each observing epoch in order to fit for time-variable dispersion delays. We describe our methods for data processing, time-of-arrival (TOA) calculation, and the implementation of a new, automated method for removing outlier TOAs. We fit a timing model for each pulsar that includes spin, astrometric, and (for binary pulsars) orbital parameters; time-variable dispersion delays; and parameters that quantify pulse-profile evolution with frequency. The timing solutions provide three new parallax measurements, two new Shapiro delay measurements, and two new measurements of significant orbital-period variations. We fit models that characterize sources of noise for each pulsar. We find that 11 pulsars show significant red noise, with generally smaller spectral indices than typically measured for non-recycled pulsars, possibly suggesting a different origin. A companion paper uses these data to constrain the strength of the gravitational-wave background.

We present a multi-wavelength catalog in the Subaru/XMM-Newton Deep Field (SXDF) as part of the Spitzer Large Area Survey with Hyper-Suprime-Cam (SPLASH). We include the newly acquired optical data from the Hyper-Suprime-Cam Subaru Strategic Program, accompanied by IRAC coverage from the SPLASH survey. All available optical and near-infrared data is homogenized and resampled on a common astrometric reference frame. Source detection is done using a multi-wavelength detection image including the u-band to recover the bluest objects. We measure multi-wavelength photometry and compute photometric redshifts as well as physical properties for ∼1.17 million objects over ∼4.2 deg2, with ∼800,000 objects in the 2.4 deg2 HSC-Ultra-Deep coverage. Using the available spectroscopic redshifts from various surveys over the range of 0 < z < 6, we verify the performance of the photometric redshifts and we find a normalized median absolute deviation of 0.023 and outlier fraction of 3.2%. The SPLASH-SXDF catalog is a valuable, publicly available resource, perfectly suited for studying galaxies in the early universe and tracing their evolution through cosmic time.
A New Equilibrium State for Singly Synchronous Binary Asteroids
Authors: Golubov Oleksiy , Unukovych Vladyslav , Scheeres Daniel J.
Published: April 2018

The evolution of rotation states of small asteroids is governed by the Yarkovsky–O’Keefe–Radzievskii–Paddack (YORP) effect, nonetheless some asteroids can stop their YORP evolution by attaining a stable equilibrium. The same is true for binary asteroids subjected to the binary YORP (BYORP) effect. Here we discuss a new type of equilibrium that combines these two, which is possible in a singly synchronous binary system. This equilibrium occurs when the normal YORP, the tangential YORP, and the BYORP compensate each other, and tidal torques distribute the angular momentum between the components of the system and dissipate energy. If unperturbed, such a system would remain singly synchronous in perpetuity with constant spin and orbit rates, as the tidal torques dissipate the incoming energy from impinging sunlight at the same rate. The probability of the existence of this kind of equilibrium in a binary system is found to be on the order of a few percent.
Impact of supply chain actor citizenship behavior on supply chain learning processes
Authors: Liyanage H. L.
Published: April 2018

Critical evaluation of early literature into supply chain learning indicates lack of research into the impact of supply chain actor citizenship behavior on supply chain learning processes. Therefore, this study explores the impact of supply chain actor citizenship behavior impact on supply chain learning processes. The study uses constructivist epistemology, interpretative theoretical perspective, case study research methodology and grounded theory thematic technique in data analysis. Findings of the study indicate that different elements of the supply chain actor citizenship behavior concept are connected to different levels of supply chain learning processes. Self-development is found to have an impact on intuition process, helping behavior is found to have an impact on interpretation process, tolerance is found to have an impact on integration process and constructiveness is found to have an impact on institutionalization process. An original contribution to theory includes extending organizational learning theory and citizenship behavior concept to supply chain context. And practitioners are recommended to explore dynamics of self-development, helping behavior, tolerance, and constructiveness on enhancing supply chain learning processes.

Unexpected circumstances with respect to the social and economic conditions, the stock market indices have been moving up and down with high volatility. This study examines the equilibrium relationships between the stock market indices and macro-economic factors in Sri Lankan during the period from January 2009 to December 2016 to capture the linear inter-dependencies, by using Vector Autoregressive Regression and Vector Error Correlation Model. Estimated co-integration rank test and Max-eigenvalue test suggested that there are two co-integration equations exist at the 0.05 level of significance. Furthermore, findings revealed that macroeconomic variables have direct effect on high volatility in Stock Market fluctuations. Moreover, the results concluded that Colombo Stock Exchange (CSE) is highly sensitive to the macroeconomic variables such as real gross domestic product and broad money supply.
Clonal Bifurcation of Foxp3 Expression Visualized in Thymocytes and T Cells

Regulatory T cells (Tregs) are crucial for suppressing autoimmunity and inflammation mediated by conventional T cells. To be useful, some Tregs should have overlapping specificity with relevant self-reactive or pathogen-specific clones. Whether matching recognition between Tregs and non-Tregs might arise through stochastic or deterministic mechanisms has not been addressed. We tested the hypothesis that some Tregs that arise in the thymus or that are induced during Ag-driven expansion of conventional CD4+ T cells might be clonally related to non-Tregs by virtue of asymmetric Foxp3 induction during cell division. We isolated mouse CD4+ thymocytes dividing in vivo, wherein sibling cells exhibited discordant expression of Foxp3 and CD25. Under in vitro conditions that stimulate induced Tregs from conventional mouse CD4+ T cells, we found a requirement for cell cycle progression to achieve Foxp3 induction. Moreover, a substantial fraction of sibling cell pairs arising from induced Treg stimulation also contained discordant expression of Foxp3. Division-linked yet asymmetric induction of Treg fate offers potential mechanisms to anticipate peripheral self-reactivity during thymic selection as well as produce precise, de novo counterregulation during CD4+ T cell–mediated immune responses.
