Role of Identity in Creating Work Centrality among Young Sri Lankan Professionals in the Era of Late Capitalism

This paper explores how contemporary young Sri Lankan professionals’ value centrality of work in their lives and how this perception is shaped by their identities. Based on the social constructionist paradigm, we have used qualitative methodology to explore the issue. Purposive sampling was employed in selecting the respondents for the study and in-depth interviews and group discussions were used as data collection methods. It was thus revealed that the respondents placed a high value in their work roles, which is mainly due to the identity created through work. Even though some respondents’ views indicated a form of identity fragmentation, they were not directly linked with the consequences of contemporary postmodern, late capital social conditions. Further analysis into the dominant role of identity formation in creating work revealed that the national culture plays a dominant role in shaping the work centrality among young Sri Lankan professionals even in the era of late capitalism.
On the Potential Role of the Antioxidant Couple Vitamin E/Selenium Taken by the Oral Route in Skin and Hair Health

The relationship between oxidative stress and skin aging/disorders is well established. Many topical and oral antioxidants (vitamins C and E, carotenoids, polyphenols) have been proposed to protect the skin against the deleterious effect induced by increased reactive oxygen species production, particularly in the context of sun exposure. In this review, we focused on the combination of vitamin E and selenium taken in supplements since both molecules act in synergy either by non-enzymatic and enzymatic pathways to eliminate skin lipids peroxides, which are strongly implicated in skin and hair disorders.

Particle transport in asymmetrically modulated pores

Brownian motion plays an important role in the separation of small particles and molecules, but generally leads to undirected motion or intermixing by diffusion. Matthias and Müller (2003 Nature 424 53–7) reported on the experimental realization of a drift ratchet, a microfluidic particle transport mechanism that utilizes random fluctuations instead, i.e. a Brownian motor. Here, we offer a new interpretation of this previously published work on the drift ratchet. New experiments, which allow us to distinguish between particles of different sizes, as well as a re-examination of the original work, lead to the conclusion that the measured particle transport does not result from a ratchet effect. We demonstrate that the transport is caused by convection instead. While our result challenges one specific type of experiment, we do not assess the feasibility of a drift ratchet in principle. Instead, we identify the experimental conditions that need to be fulfilled for the successful separation of particles.
On the structure and energetics of quasar broad absorption-line outflows

Quasar accretion-disk outflows might play an important role in galaxy evolution, but they are notoriously difficult to study due to line saturation and blending problems in the Ly-alpha forest. We circumvent these problems by constructing median composite spectra of diverse broad absorption lines (BALs) and `mini-BALs' in SDSS-III BOSS quasars at redshifts 2.3 22.7, and large ionisation parameters log U > -0.5 are common. (3) Different observed depths in saturated lines identify inhomogeneous partial covering on spatial scales 3 x 10^5 cm^-3 and maximum radial distances R 0.005(R/1.2pc) sufficient (by some estimates) for feedback to galaxy evolution. (6) LoBAL quasars have the largest median outflow column densities, highest velocities, and weakest HeII 1640 emission in our study; they appear to be at one extreme in a distribution of quasar properties where softer ionising spectra drive more powerful outflows.
MAX 4 and MAX 5 Cosmic Microwave Background Anisotropy Measurement Constraints on Open and Flat-Λ Cold Dark Matter Cosmogonies

We account for experimental and observational uncertainties in likelihood analyses of cosmic microwave background (CMB) anisotropy data from the MAX 4 and MAX 5 experiments. These analyses use CMB anisotropy spectra predicted in open and spatially flat Λ cold dark matter cosmogonies. Among the models considered, the combined MAX data set is most consistent with the CMB anisotropy shape in Ω0 ~ 0.1-0.2 open models and less so with that in old (t0 ≳ 15-16 Gyr, i.e., low-h), high baryon density (ΩB ≳ 0.0175 h-2), low-density (Ω0 ~ 0.2-0.4), flat-Λ models. The MAX data alone do not rule out any of the models we consider at the 2 σ level. Model normalizations deduced from the combined MAX data are consistent with those drawn from the UCSB South Pole 1994 data, except for the flat bandpower model for which MAX favors a higher normalization. The combined MAX data normalization for open models with Ω0 ~ 0.1-0.2 is higher than the upper 2 σ value of the DMR normalization. The combined MAX data normalization for old (low-h), high baryon density, low-density flat-Λ models is below the lower 2 σ value of the DMR normalization. Open models with Ω0 ~ 0.4-0.5 are not far from the shape most favored by the MAX data, and for these models, the MAX and DMR normalizations overlap. The MAX and DMR normalizations also overlap for Ω0 = 1 and some higher h, lower ΩB, low-density flat-Λ models.
The open cluster King 1 in the second quadrant

We analyse the poorly-studied open cluster King~1 in the second Galactic quadrant. From wide-field photometry we have studied the spatial distribution of this cluster. We determined that the centre of King~1 is located at $\alpha_{2000}=00^{\rm h}22^{\rm m}$ and $\delta_{2000}=+64\degr23\arcmin$. By parameterizing the stellar density with a King profile we have obtained a central density of $\rho_{0}=6.5\pm0.2$ star arcmin$^{-2}$ and a core radius of $r_{\rm core}=1\farcm9\pm0\farcm2$. By comparing the observed color-magnitude diagram of King~1 with those of similar open clusters and with different sets of isochrones, we have estimated an age of $2.8\pm0.3$ Gyr, a distance modulus of $(m-M)_{\rm o}=10.6\pm0.1$ mag, and a reddening of $E(B-V)=0.80\pm0.05$ mag. To complete our analysis we acquired medium resolution spectra for 189 stars in the area of King~1. From their derived radial velocities we determined an average velocity $\left\langle V_r\right\rangle $=-53.1$\pm$3.1 km s$^{-1}$. From the strength of the infrared \mbox{Ca\,{\sc ii}} lines in red giants we have determined an average metallicity of $\left\langle [M/H]\right\rangle$=+0.07$\pm$0.08 dex. From spectral synthesis we have also estimated an $\alpha$-elements abundance of $\left\langle [\alpha/M]\right\rangle$=-0.10$\pm$0.08 dex.
Assessing the sensitivity of PINGU to effective dark matter-nucleon interactions

We calculate the sensitivity of next generation neutrino telescopes to the 28 (isoscalar and isovector) coupling constants defining the non-relativistic effective theory of (spin 1/2) dark matter (DM)-nucleon interactions. We take as a benchmark detector the proposed Precision IceCube Next Generation Upgrade (PINGU), although our results are valid for any other neutrino telescope of similar effective volume. We express PINGU's sensitivity in terms of 5σ sensitivity contours in the DM mass-coupling constant plane, and compare our sensitivity contours with the 90% C.L. exclusion limits on the same coupling constants that we obtain from a reanalysis of the null result of current DM searches at IceCube/DeepCore. We find that PINGU can effectively probe not only the canonical spin-independent and spin-dependent DM-nucleon interactions, but also some of the velocity-dependent or momentum-dependent interactions that generate DM-nucleus scattering cross sections scaling like the number of nucleons squared. We also find that PINGU's 5σ sensitivity contours are significantly below current IceCube/DeepCore 90% C.L. exclusion limits when bb̄ is the leading DM annihilation channel. This result shows the importance of lowering the experimental energy threshold when probing models that generate soft neutrino energy spectra, and holds true independently of the assumed DM-nucleon interaction and for all DM masses tested here. When DM primarily annihilates into ττ̄, a PINGU-like detector will improve upon current exclusion limits for DM masses below 30 GeV, independently of the assumed DM-nucleon interaction.
The “Boys’ Club”, sexual harassment, and discriminatory resourcing: An exploration of the barriers faced by women sport officials in Australian basketball

Sport official's experience of abuse in their role is well documented, but the additional gendered barriers that women officials face are not. This study used Concept Mapping to explore the most important and frequent barriers that women referees and officials in Australian basketball face. Results were analyzed according to the Socio-Ecological Framework with a feminist lens, which demonstrated the complexity and interconnectedness of barriers between different levels. While participants were not specifically asked about gendered experiences, the results indicated that barriers were overwhelmingly gendered at every level, including discriminatory resourcing, lack of senior women, and concerningly, incidents of sexual harassment. This research sheds new light on the experience of women officials and the organizational and societal barriers that limit their careers and make their workplace unsafe. Finally, it discusses where the locus of responsibility lies in addressing these issues for women sport officials, placing emphasis on the role of organizations.

The organism is found to cause sepsis and is also reported to cause blood stream infections in malignancy. Here, we present a case series of five patients with sepsis in which an unsual violet pigment producing BCC was isolated. Keywords: Violet pigment, Burkholderia, Sepsis, Malignancy
Fracture Behavior of Wood Under Mode I Loading in Tangential Direction

The aim of this study was to determine the fracture behavior of southern yellow pine (Pinus taeda L.) and red oak (Quercus falcata) wood under mode I loading in the tangential-radial and tangential-longitudinal crack propagation systems by a compact tension test method. The results of the study indicated that, in general, red oak had a significantly different fracture behavior than southern yellow pine for each of the two crack propagation systems. The fracture toughness was higher in the tangential-radial crack propagation system than that in the tangential-longitudinal crack system, but there was no significant difference between the two crack propagation systems for southern yellow pine. The specific fracture energy of the tangential-longitudinal crack propagation system for both wood species was significantly lower than that of the tangential-radial crack propagation system. It means that more energy per unit area for the tangential-radial crack propagation system was needed to separate a wood sample into two halves. The difference in the fracture behavior of wood by the crack propagation system can be explained by the structural features of the tested samples since the crack propagation of the tangentialradial system crosses the annual ring and wood fibers can bridge the crack surface.
Solving the Bose–Hubbard Model with Machine Learning

Motivated by the recent successful application of artificial neural networks to quantum many-body problems [G. Carleo and M. Troyer, Science 355, 602 (2017)], a method to calculate the ground state of the Bose–Hubbard model using a feedforward neural network is proposed. The results are in good agreement with those obtained by exact diagonalization and the Gutzwiller approximation. The method of neural-network quantum states is promising for solving quantum many-body problems of ultracold atoms in optical lattices.

The Molecular Gas Distribution and Schmidt Law in M33

The relationship between the star formation rate and surface density of neutral gas within the disk of M33 is examined with new imaging observations of 12CO J = 1-0 emission gathered with the Five College Radio Astronomy Observatory (FCRAO) 14 m telescope and IRAS HiRes images of the 60 and 100 μm emission. The Schmidt law, ΣSFR ~ Σ, is constructed using radial profiles of the H I 21 cm, CO, and far-infrared emission. We identify a strong correlation between the star formation rate and molecular gas surface density. This suggests that the condensation of giant molecular clouds (GMCs) is the limiting step to star formation within the M33 disk. The corresponding molecular Schmidt index, nmol, is 1.36 ± 0.08. The star formation rate has a steep dependence on total mass gas surface density, (Σ + Σ), owing to the shallow radial profile of the atomic gas that dominates the total gas surface density for most radii. The disk pressure of the gas is shown to play a prominent role in regulating the molecular gas fraction in M33.
Internal Variations in Empirical Oxygen Abundances for Giant H ii Regions in the Galaxy NGC 2403

This paper presents a spectroscopic investigation of 11 regions in the nearby galaxy NGC 2403. The regions are observed with a long-slit spectrograph mounted on the 2.16 m telescope at XingLong station of National Astronomical Observatories of China. For each of the regions, spectra are extracted at different nebular radii along the slit-coverage. Oxygen abundances are empirically estimated from the strong-line indices R23, , , and N2 for each spectrophotometric unit, with both observation- and model-based calibrations adopted into the derivation. Radial profiles of these diversely estimated abundances are drawn for each nebula. In the results, the oxygen abundances separately estimated with the prescriptions on the basis of observations and models, albeit from the same spectral index, systematically deviate from each other; at the same time, the spectral indices R23 and are distributed with flat profiles, whereas N2 and exhibit apparent gradients with the nebular radius. Because our study naturally samples various ionization levels, which inherently decline at larger radii within individual regions, the radial distributions indicate not only the robustness of R23 and against ionization variations but also the sensitivity of N2 and to the ionization parameter. The results in this paper provide observational corroboration of the theoretical prediction about the deviation in the empirical abundance diagnostics. Our future work is planned to investigate metal-poor regions with measurable Te, in an attempt to recalibrate the strong-line indices and consequently disclose the cause of the discrepancies between the empirical oxygen abundances.
Planetary Radio Interferometry and Doppler Experiment (PRIDE) technique: A test case of the Mars Express Phobos Flyby. II. Doppler tracking: Formulation of observed and computed values, and noise budget

Context. Closed-loop Doppler data obtained by deep space tracking networks, such as the NASA Deep Space Network (DSN) and the ESA tracking station network (Estrack), are routinely used for navigation and science applications. By shadow tracking the spacecraft signal, Earth-based radio telescopes involved in the Planetary Radio Interferometry and Doppler Experiment (PRIDE) can provide open-loop Doppler tracking data only when the dedicated deep space tracking facilities are operating in closed-loop mode. Aims. We explain the data processing pipeline in detail and discuss the capabilities of the technique and its potential applications in planetary science. Methods. We provide the formulation of the observed and computed values of the Doppler data in PRIDE tracking of spacecraft and demonstrate the quality of the results using an experiment with the ESA Mars Express spacecraft as a test case. Results. We find that the Doppler residuals and the corresponding noise budget of the open-loop Doppler detections obtained with the PRIDE stations compare to the closed-loop Doppler detections obtained with dedicated deep space tracking facilities.
Reform of the Health Insurance Funding Model to Improve the Care of Noncommunicable Diseases Patients in Saudi Arabia

Health insurance models are being considered as part of health system reforms in Saudi Arabia. This paper assesses the attributes of health funding models that support better control of non-communicable diseases (NCDs) and perspectives on health insurance as a model from the perspective of patients, clinicians, and managers. The study employed a mixed-methods research design that included quantitative and qualitative data gathering and analysis. Study findings indicated concerns that the current health funding mechanism is financially unsustainable and, as a result, there will be a greater reliance on personal health insurance to support government spending on healthcare. Essential elements of any health insurance model to support effective NCD management identified from a review of the literature and interviews include the following: ensuring continuity of care and equity; funding chronic disease prevention interventions; prioritising primary healthcare; and maintaining the principle of community rating to prevent insurers from discriminating against members. Other desirable attributes for the funding model includes collaboration across primary, secondary, and tertiary care. Healthcare finance reform aimed at adopting and increasing personal health insurance coverage may play a critical role in extending access to healthcare, eliminating health inequities, enhancing population health, and reducing government spending on healthcare if appropriately considered.
DAMAGE OF CONCRETE IN FATIGUE

Three‐point bending fatigue tests are performed on two types of concrete using two different R ratios. The maximum strain is recorded during the tests. A damage mechanics model for the fatigue of concrete is proposed. It is based on a damage parameter proportional to the irreversible increment per cycle of the largest principal positive strain. This model predicts both the evolution of the strain as a function of the number of cycles and the fatigue life based on the initial strain and the strain increments. Comparisons of our experimental results are made with the model. Results reported by Holmen for compression fatigue tests are also used for comparison.
Date of Planting, Spacing and Integrated Nutrient Management Practices Improves Soil Microbial Populations and Soil Fertility Status Under Rice -Arhar Cropping System in Acidic Soils of Eastern India

ABSTRACT Rice (Oryza sativa L.) is a nutrient-exhausting crop, sustainable productivity of rice based cropping system can be achieved through appropriate nutrient management and crop diversification through incorporation of pulse into this system. Considering the above facts, a field experiment on rice-arhar system was conducted for two consecutive years (2018 and 2019) during kharif seasons at the Agronomy research Farm of Odisha University of Agriculture and Technology, Bhubaneswar having sub-humid climate with two date of planting, three nutrient management and three row spacing. Soil physico-chemical properties like N, soil organic carbon (SOC) was found higher with earlier planting, soil-test-based fertilizer Recommendation (STBFR) + Farmyard Manure (FYM) in rice and 30 cm row spacing in arhar. The system nutrient uptake of 219.76 kg N ha−1, 38.25 kg P ha−1 and 197.29 kg K ha−1 and microbial activities in terms of dehydrogenase activity (DHA) (241.9 mg TPF g−1 soil 24 hr−1), alkaline phosphatase activity (APA) (376.7 mg p-nitrophenol kg−1 soil 1 h−1), microbial biomass Carbon (MBC) (260.3 μg g−1 of dry soil), microbial biomass nitrogen (MBN) (93.7 μg N g−1 soil) was registered with earlier planting, STBFR + FYM in rice and 30 cm row spacing in arhar. Higher positive N and K balance over initial (actual balance) in rice-arhar cropping system was observed in the treatment fertilized with both organic and inorganic sources of nutrients.
Association between Parkinson’s Disease and Diabetes Mellitus: From Epidemiology, Pathophysiology and Prevention to Treatment

Diabetes mellitus (DM) and Parkinson’s disease (PD) are both age-related diseases of global concern being among the most common chronic metabolic and neurodegenerative diseases, respectively. While both diseases can be genetically inherited, environmental factors play a vital role in their pathogenesis. Moreover, DM and PD have common underlying molecular mechanisms, such as misfolded protein aggregation, mitochondrial dysfunction, oxidative stress, chronic inflammation, and microbial dysbiosis. Recently, epidemiological and experimental studies have reported that DM affects the incidence and progression of PD. Moreover, certain antidiabetic drugs have been proven to decrease the risk of PD and delay its progression. In this review, we elucidate the epidemiological and pathophysiological association between DM and PD and summarize the antidiabetic drugs used in animal models and clinical trials of PD, which may provide reference for the clinical translation of antidiabetic drugs in PD treatment.
