Abstract. In this study, we analyse the climatology of ionosphere over Nepal based on
GPS-derived vertical total electron content (VTEC) observed from four stations as defined in Table 1: KKN4 (27.80∘ N, 85.27∘ E), GRHI (27.95∘ N, 82.49∘ E), JMSM (28.80∘ N, 83.74∘ E) and DLPA (28.98∘ N, 82.81∘ E) during the years 2008 to 2018. The study illustrates the diurnal, monthly, annual, seasonal and solar cycle variations in VTEC during all times of solar cycle 24. The results clearly reveal the presence of equinoctial asymmetry in TEC, which is more pronounced in maximum phases of solar cycle in the year 2014 at KKN4 station, followed by descending, ascending and minimum phases. Diurnal variations in VTEC showed the short-lived day minimum which occurs between 05:00 to 06:00 LT (local time) at all the stations considered, with
diurnal peaks between 12:00 and 15:00 LT. The maximum value of
TEC is observed more often during the spring equinox than the autumn equinox, with a few asymmetries. Seasonal variation in TEC is observed to be a manifestation of variations in solar flux, particularly regarding the level of solar flux in consecutive solstices.
Carbon dynamics at the river-estuarine transition: a comparison among tributaries of Chesapeake Bay
Authors: Bukaveckas Paul
Published: August 2021

Abstract. Sources and transformation of C were quantified using mass balance and ecosystem metabolism data for the upper segments of the James, Pamunkey and Mattaponi Estuaries. The goal was to assess the role of external (river inputs & tidal exchange) vs. internal (metabolism) drivers in influencing the forms and fluxes of C. C forms and their response to river discharge differed among the estuaries based on their physiographic setting. The James, which receives the bulk of inputs from upland areas (Piedmont and Mountain), exhibited a higher ratio of inorganic to organic C, and larger inputs of POC. The Pamunkey and Mattaponi receive a greater proportion of inputs from lowland (Coastal Plain) areas, which were characterized by low DIC and POC, and elevated DOC. We anticipated that transport processes would dominate during colder months when discharge is elevated and metabolism is low, and that biological processes would predominate in summer, leading to attenuation of C through-puts via de-gassing of CO2. Contrary to expectations, highest retention of OC occurred during periods of high through-put, as elevated discharge resulted in greater loading and retention of POC. In summer, internal cycling of C via production and respiration was large in comparison to external forcing despite the large riverine influence in these upper estuarine segments. The estuaries were found to be net heterotrophic based on retention of OC, export of DIC, low GPP relative to ER, and a net flux of CO2 to the atmosphere. In the James, greater contributions from phytoplankton production resulted in a closer balance between GPP and ER, with autochthonous production exceeding allochthonous inputs. Combining the mass balance and metabolism data with bioenergetics provided a basis for estimating the proportion of C inputs utilized by the dominant metazoan. The findings suggest that invasive catfish utilize 15 % of total OM inputs and up to 40 % of allochthonous inputs to the James.
Confined fission-track revelation in apatite: how it works and why it matters
Authors: Ketcham Richard A. , Tamer Murat T.
Published: August 2021

Abstract. We present a new model for the etching and revelation of
confined fission tracks in apatite based on variable along-track etching
velocity, vT(x). Insights from step-etching experiments and theoretical
energy loss rates of fission fragments suggest two end-member etching
structures: constant-core, with a central zone of constant etching rate that
then falls off toward track tips; and linear, in which etching rates fall
linearly from the midpoint to the tips. From these, we construct a
characterization of confined track revelation that encompasses all relevant
processes, including penetration and widening of semi-tracks etching in from
the polished grain surface, intersection with and expansion of confined
tracks, and analyst selection of which tracks to measure and which to
bypass. Both etching structures are able to fit step-etching data from five
sets of paired experiments of fossil tracks and unannealed and annealed
induced tracks in Durango apatite, supporting the correctness of our approach and providing a
series of insights into the theory and practice of fission-track
thermochronology. Etching rates for annealed induced tracks are much faster
than those for unannealed induced and spontaneous tracks, impacting the
relative efficiency of both confined track length and density measurements
and suggesting that high-temperature laboratory annealing may induce a
transformation in track cores that does not occur at geological conditions
of partial annealing. The model quantifies how variation in analyst
selection criteria, summarized as the ratio of along-track to bulk etching
velocity at the etched track tip (vT/vB), likely plays a first-order
role in the reproducibility of confined length measurements. It also
accounts for and provides an estimate of the large proportion of tracks that
are intersected but not measured, and it shows how length biasing is likely to
be an insufficient basis for predicting the relative probability of
detection of different track populations. The vT(x) model provides an
approach to optimizing etching conditions, linking track length measurements
across etching protocols, and discerning new information on the underlying
structure of fission tracks.

Published: August 2021

Abstract. Paleo-bathymetric reconstructions provide boundary conditions to numerical models of ice sheet evolution and ocean circulation that are critical to understanding their evolution through time. The geological community lacks a complex open-source tool that allows for community implementations and strengthens research synergies. To fill this gap, we present PALEOSTRIPv1.0, a MATLAB open-source software designed to perform 1D, 2D, and 3D backtracking of paleo-bathymetries. PALEOSTRIP comes with a graphical user interface (GUI) to facilitate computation of sensitivity tests and to allow the users to switch all the different processes on and off and thus separate the various aspects of backtracking. As such, all physical parameters can be modified from the GUI. It includes 3D flexural isostasy, 1D thermal subsidence, and possibilities to correct for prescribed sea level and dynamical topography changes. In the following, we detail the physics embedded within PALEOSTRIP, and we show its application using a drilling site (1D), a transect (2D), and a map (3D), taking the Ross Sea (Antarctica) as a case study. PALEOSTRIP has been designed to be modular and to allow users to insert their own implementations.
MagIC v5.10: a two-dimensional MPI distribution for pseudo-spectral magneto hydrodynamics simulations in spherical geometry
Authors: Lago Rafael , Gastine Thomas , Dannert Tilman , Rampp Markus , Wicht Johannes
Published: August 2021

Abstract. We discuss two parallelization schemes for MagIC, an open-source, high-performance, pseudo-spectral code for the numerical solution of the magneto hydrodynamics equations in a rotating spherical shell. MagIC calculates the non-linear terms on a numerical grid in spherical coordinates while the time step updates are performed on radial grid points with a spherical harmonic representation of the lateral directions. Several transforms are required to switch between the different representations. The established hybrid implementation of MagIC uses MPI-parallelization in radius and relies on existing fast spherical transforms using OpenMP. Our new two-dimensional MPI decomposition implementation also distributes the latitudes or the azimuthal wavenumbers across the available MPI tasks/compute cores. We discuss several non-trivial algorithmic optimizations and the different data distribution layouts employed by our scheme. In particular, the two-dimensional distribution data layout yields a code that strongly scales well beyond the limit of the current one-dimensional distribution. We also show that the two-dimensional distribution implementation, although not yet fully optimized, can already be faster than the existing finely optimized hybrid implementation when using many thousands of CPU cores. Our analysis indicates that the two-dimensional distribution variant can be further optimized to also surpass the performance of the one-dimensional distribution for a few thousand cores.
Sources and pathways of biocides and their transformation products in urban storm water infrastructure of a 2 ha urban district

Published: August 2021

Abstract. Biocides used in film protection products leaching from facades are known to be a potential threat to the environment. This study identifies individual sources and entry pathways in a small-scale urban area. We investigate emissions of commonly used biocides (terbutryn, diuron, and octylisothiazolinone – OIT) and some of their transformation products (TPs; diuron-desmethyl, terbumeton, terbuthylazine-2-hydroxy, and terbutryn-desethyl) from a 2 ha residential area 13 years after construction has ended. Sampling utilizes existing urban water infrastructure representative for decentralized storm water management in
central and northern Europe and applies a two-step approach to (a) determine the occurrence of biocides above water quality limits (i.e., predicted no-effect concentration, PNEC) and (b) identify source areas and characterize entry pathways into surface and groundwater. Monitoring focuses on the analysis of selected biocides and TPs by liquid chromatography–mass spectrometry/mass spectrometry (LC-MS/MS) in water samples taken from facades, rainwater pipes, drainage, and storm water infiltration systems. In standing water in a swale, we found high concentrations of diuron (174 ng L−1) and terbutryn (40 ng L−1) above PNEC for surface water. We confirmed expected sources, i.e., facades. Sampling of rain downpipes from flat roofs identified additional sources of all biocides and two TPs of terbutryn and one TP of diuron. Diuron and terbutryn were found in three drainage pipes representing different entry pathways of biocides. In one drainage pipe collecting road runoff, only diuron-desmethyl and terbutryn-desethyl were detected. In two other drainage pipes collecting infiltrated water through soil, terbuthylazine-2-hydroxy was additionally detected. One of the pipes collecting infiltrated water through soil concentration showed the highest concentrations of terbutryn and two of its TPs (terbutryn-desethyl and terbuthylazine-2-hydroxy). This suggests a high leaching potential of terbutryn. The applied two-step approach determined sources and pathways of biocide and their TPs. This study contributes to expanding knowledge on their entry and distribution and, thus, eventually towards reducing emissions.

Published: August 2021

Abstract. This paper presents an application of PS-InSAR method for determining landslide displacement velocity in Van Yen district, Yen Bai province, Vietnam. The used tools for processing data is a combination of two free software, SNAP 7.0 and STaMPS 4.1. With 27 Sentinel-1A images in descending direction acquired from 11th January 2019 to 1st March 2021, the landslide displacement values were calculated and exported. There were locations in which landslides correctly appeared, such as Lang Thip, Xuan Tam, Chau Que Ha, Phong Du Thuong communes and along provincial road 151. Landslide rate is determined from SAR image series with average value less than 16.5 mm/y in places with high terrain and steep slope. The distribution of permanent scatter (PS) points for landslides often appeared along the road slopes, especially the inter-communal and inter-provincial roads that have not been reinforced with structural mitigation measures. In 2013 a field survey was conducted by the Vietnam Institute of Geosciences and Mineral Resources for this area which was used to validate the results from SAR processing. Landslide velocity charts at certain landslide sites were derived. The current study demonstrated the feasibility of the method as well as the usage of Sentinel-1 data for land deformation monitoring in the mountainous area.
ASSESSING CROPLAND ABANDONMENT FROM VIOLENT CONFLICT IN CENTRAL MALI WITH SENTINEL-2 AND GOOGLE EARTH ENGINE
Authors: Boudinaud L. , Orenstein S. A.
Published: August 2021

Abstract. The proposed analysis based on Sentinel-2 imagery provides evidence of impacts of the conflict in the Mopti region (central Mali), which has led to widescale cropland abandonment. This area is characterized by rapidly rising levels of violence since 2018, due to the presence of armed groups and the proliferation of self-defence militias. This study investigates how high-resolution optical imagery can help evaluate the linkages between violence and land cover / land use (LCLU) change. The processing environment of Google Earth Engine was used to generate the so-called 3-Period TimeScan (3PTS) product, a RGB composite combining the maximum NDVI values in the beginning, in the middle and in the end of the growing season, used to single out cultivated land for each year of interest. Theoretically, the period between June 15th and October 15th covers an annual agricultural cycle for the considered area; consequently, images acquired during that period were used to generate the 3PTS composites for the year of interest (2019) and for pre-conflict years. By comparing the situations before and after the start of the crisis, each populated site was categorized according to the degree of cropland change detected in its surroundings. The resulting overview map enables a regional-scale interpretation of farming activities in 2019, clearly highlighting localized areas of cropland abandonment in the region and showing a strong spatial correlation with incidence of conflict.

Published: August 2021

Abstract. Background: The aim of this study is to summarize and improve knowledge regarding a Candida fracture-related infection (CFRI) through a systematic review on the topic, accompanied by a case report. Methods: A systematic review and meta-analysis based on PRISMA statement were conducted on the CFRI topic. The following combined search terms were used to explore PubMed, Cochrane, and the Embase database: “fungal infection”, “candida”, “fracture related infection”, “bone infection”, “orthopedic infection”, “internal fixation”, “post-traumatic infection”, and “osteomyelitis”. Results: Out of 1514 records, only 5 case reports matched the selection criteria and were included. Moreover, a new case of CFRI, not previously described, was reported in this paper and reviewed. The main risk factors for CFRI were open wounds (three cases) and immunodeficiency (three cases). Initial improvement of clinical and laboratory signs of infection was noted in all cases. In the available short-term follow-up (mean 12.1 months; range 3–42), the reoperation rate was 33.3 %. Using a strategy based on extensive debridement/resection methods and prolonged systemic antifungal therapy (mean 8.8 weeks; range 6–18), four of six cases (66.6 %) were cured. Bone union occurred in three out of six cases. Conclusion: There is very low-quality evidence available regarding CFRI. Candida infections in surgically treated fractures are rare but difficult-to-treat events, with a slow onset, unspecific symptoms or signs, and a significant relapse risk; therefore, they still represent a current diagnostic challenge. The existing fracture-related infection treatment algorithm combined with long-term systemic antifungal therapy has an anecdotal value and needs more extensive studies to be validated.

Abstract. Coincident wide-angle and multi-channel seismic data acquired within the scope of the PAMELA Moz3-5 project allow us to reconsider the formation mechanism of East African margins offshore of southern Mozambique. This study specifically focuses on the sedimentary and deep-crustal architecture of the Limpopo margin (LM) that fringes the eastern edge of the Mozambique’s Coastal Plain (MCP) and its offshore southern prolongation the North Natal Valley (NNV). It relies primarily on the MZ3 profile that runs obliquely from the northeastern NNV towards the Mozambique basin (MB) with additional inputs from a tectonostratigraphy analysis of industrial onshore–offshore seismic lines and nearby or crossing velocity models from companion studies. Over its entire N–S extension the LM appears segmented into (1) a western domain that shows the progressive eastward crustal thinning and termination of the MCP/NNV continental crust and its overlying pre-Neocomian volcano-sedimentary basement and (2) a central corridor of anomalous crust bounded to the east by the Mozambique fracture zone (MFZ) and the oceanic crust of the MB. A prominent basement high marks the boundary between these two domains. Its development was most probably controlled by a steep and deeply rooted fault, i.e., the Limpopo fault. We infer that strike-slip or slightly transtensional rifting occurred along the LM and was accommodated along this Limpopo fault. At depth we propose that ductile shearing was responsible for the thinning of the continental crust and an oceanward flow of lower crustal material. This process was accompanied by intense magmatism that extruded to form the volcanic basement and gave the corridor its peculiar structure and mixed nature. The whole region remained at a relative high level during the rifting period and a shallow marine environment dominated the pre-Neocomian period during the early phase of continent–ocean interaction. It is only some time after break-up in the MB and the initiation of the MFZ that decoupling occurred between the MCP/NNV and the corridor, allowing for the latter to subside and become covered by deep marine sediments. A scenario for the early evolution and formation of the LM is proposed taking into account both recent kinematic and geological constraints. It implies that no or little change in extensional direction occurred between the intra-continental rifting and subsequent phase of continent–ocean interaction.
Wake properties and power output of very large wind farms for different meteorological conditions and turbine spacings: A large-eddy simulation case study for the German Bight
Authors: Maas Oliver , Raasch Siegfried
Published: August 2021

Abstract. Germany’s expansion target for offshore wind power capacity of 40 GW by the year 2040 can only be reached if large portions of the Exclusive Economic Zone in the German Bight are equipped with wind farms. Because these wind farm clusters will be much larger than existing wind farms, it is unknown how they affect the boundary layer flow and how much power they will produce. The objective of this large-eddy-simulation study is to investigate the wake properties and the power output of very large potential wind farms in the German Bight for different turbine spacings, stabilities and boundary layer heights. The results show that very large wind farms cause flow effects that small wind farms do not. These effects include, but are not limited to, inversion layer displacement, counterclockwise flow deflection inside the boundary layer and clockwise flow deflection above the boundary layer. Wakes of very large wind farms are longer for shallower boundary layers and smaller turbine spacings, reaching values of more than 100 km. The wake in terms of turbulence intensity is approximately 20 km long, where longer wakes occur for convective boundary layers and shorter wakes for stable boundary layers. Very large wind farms in a shallow, stable boundary layer can excite gravity waves in the overlying free atmosphere, resulting in significant flow blockage. The power output of very large wind farms is higher for thicker boundary layers, because thick boundary layers contain more kinetic energy than thin boundary layers. The power density of the energy input by the geostrophic pressure gradient limits the power output of very large wind farms. Because this power density is very low (approximately 2 W m−2), the installed power density of very large wind farms should be small to achieve a good wind farm efficiency.

Together with the use of the internet in working life, the communication activities of organizations and the services they provide have become more productive and faster. However, problems such as the use of the internet by employees for their special purposes outside work have also emerged. This condition is defined as cyberslacking behavior in the literature, which indicates personal use of the internet by employees outside their tasks in the workplace environment. Since the sensitivity and attention to be showed by medical personnel will directly affect human health when providing healthcare services, it is necessary to put emphasis on cyberslacking behavior of healthcare professionals, especially nurses who maintain the care of patients full time. Studies investigating cyberslacking behavior in health sector are not adequate in number. This study has compiled the results of studies giving information about cyberslacking behavior in healthcare professionals.

Method: This cross-sectional study was conducted in a university hospital where 400 nurses were employed, and conducted with 154 nurses who have been working in this hospital for at least one year and volunteered to participate in the study. The data were collected with an online questionnaire consisting of three parts. The survey form contained questions about the personal, professional characteristics, and workplace environment of the nurses, and their satisfaction levels about their perceptions of quality of nursing care, the Practice Environment Scale of the Nursing Work Index. Descriptive statistics and logistic regression analysis were used in data analysis. Results: Nurses rated their perceptions of quality of nursing care (mean score: 7.53±1.85; range: 0-10). The mean score of nursing work environment scale was 2.77±0.54. In the logistic regression analysis, it was determined that nurses’ perception of quality of nursing care was affected by “provision of necessary funding sources for quality of nursing care, competency level, staffing and resource adequacy total professional experience, nurse participation in hospital affairs (Nagelkerke R2=58%, p<.05). Conclusion: The nurses’ perception of the quality of care is closely related with nursing work environment in the hospital, their perceived self-competence and duration of their professional experience. Support provided by the managers about participation in management processes, providing opportunities for employees to develop their competencies, as well as providing adequate human and other resources in the working environment, will contribute and increase the quality of care.

Moderating Effect of Strategic Improvisation on product Innovation and Performance of Manufacturing SMEs
Authors: Abubakar Ismaila , Abdullahi Ramatu , Baba Ibrahim Hadiza
Published: August 2021

In a dynamic, complex and competitive business environment, it is vital for business organisations including manufacturing SMEs to improve product innovation capabilities and increase creativity and spontaneity in order to deal with uncertainties associated with intensity and frequency of changes in the environment. This study attempts to investigate the effects of product innovation on performance of manufacturing SMEs in an emerging economy and examine the role of strategic improvisation on product innovation and performance. Data for the study was collected from 182 owners/managers of manufacturing SMEs in Nigeria. The collected data was analysed using correlation and regression techniques. Findings of the empirical study indicate that the coefﬁcient for product innovation is positive and signiﬁcant for firm performance. However, the result shows that the interaction term between product innovation and strategic improvisation is not signiﬁcant in predicting firm performance. Therefore, firms can build and enhance their performance using product innovation capabilities regardless of the present or absent of strategic improvisation in the organisation. This study provides implications for managers, entrepreneurs and government in ﬁnding the right way to performance through adopting product innovation.

The Queer Utopianism of Myra Breckinridge
Authors: Booth Nathanael Thomas
Published: August 2021

Though not often discussed as such, Gore Vidal's Myra Breckinridge (1968) is a work of queer utopianism. Myra herself is an entrancing figure—a self-created goddess who is determined to save humanity by abolishing gender itself. That her efforts ultimately fail is a testament to the queerness of her utopianism. Using Lee Edelman's discussion of “reproductive futurism” and José Esteban Muñoz's insights into the queerness of utopianism, this article analyzes the ways in which Myra Breckinridge channels both hopeful and destructive urges as a way of imagining a counter-narrative to the human catastrophe represented by the atomic bomb and the threat of overpopulation.
“The Ones Who Stay and Fight”: N. K. Jemisin's Afrofuturist Variations on a Theme by Ursula K. Le Guin
Authors: Tabone Mark A.
Published: August 2021

This article discusses N. K. Jemisin's Afrofuturist utopian short story entitled “The Ones Who Stay and Fight,” the opening story of her 2018 collection, How Long 'Til Black Future Month? As is suggested by its title, Jemisin's story is a direct reply to Ursula K. Le Guin's “The Ones Who Walk Away from Omelas,” and this article discusses the ways in which Jemisin, one of the most prominent members of a new generation of SF/Fantasy writers, pays homage to, replies to, and reimagines Le Guin's 1973 story in the twenty-first century. In particular, drawing on utopian scholarship, scholars of Afrofuturism, and the work of African American studies scholar-activists, it argues that Jemisin's utopia builds a world that embodies the “revolution of value” as well as the intersectional Black feminist praxis at the foundation of contemporary activist groups such as Black Lives Matter. It also argues for the ways in which Jemisin's text confronts common criticisms of utopia as well as the limits of the utopian imagination.
