Background
Non-steroidal anti-inflammatory drugs (NSAIDs), such as diclofenac (DCF), form a significant group of environmental contaminants. When the toxic effects of DCF on plants are analyzed, authors often focus on photosynthesis, while mitochondrial respiration is usually overlooked. Therefore, an in vivo investigation of plant mitochondria functioning under DCF treatment is needed. In the present work, we decided to use the green alga Chlamydomonas reinhardtii as a model organism.

Methods
Synchronous cultures of Chlamydomonas reinhardtii strain CC-1690 were treated with DCF at a concentration of 135.5 mg × L−1, corresponding to the toxicological value EC50/24. To assess the effects of short-term exposure to DCF on mitochondrial activity, oxygen consumption rate, mitochondrial membrane potential (MMP) and mitochondrial reactive oxygen species (mtROS) production were analyzed. To inhibit cytochrome c oxidase or alternative oxidase activity, potassium cyanide (KCN) or salicylhydroxamic acid (SHAM) were used, respectively. Moreover, the cell’s structure organization was analyzed using confocal microscopy and transmission electron microscopy.

Results
The results indicate that short-term exposure to DCF leads to an increase in oxygen consumption rate, accompanied by low MMP and reduced mtROS production by the cells in the treated populations as compared to control ones. These observations suggest an uncoupling of oxidative phosphorylation due to the disruption of mitochondrial membranes, which is consistent with the malformations in mitochondrial structures observed in electron micrographs, such as elongation, irregular forms, and degraded cristae, potentially indicating mitochondrial swelling or hyper-fission. The assumption about non-specific DCF action is further supported by comparing mitochondrial parameters in DCF-treated cells to the same parameters in cells treated with selective respiratory inhibitors: no similarities were found between the experimental variants.

Conclusions
The results obtained in this work suggest that DCF strongly affects cells that experience mild metabolic or developmental disorders, not revealed under control conditions, while more vital cells are affected only slightly, as it was already indicated in literature. In the cells suffering from DCF treatment, the drug influence on mitochondria functioning in a non-specific way, destroying the structure of mitochondrial membranes. This primary effect probably led to the mitochondrial inner membrane permeability transition and the uncoupling of oxidative phosphorylation. It can be assumed that mitochondrial dysfunction is an important factor in DCF phytotoxicity. Because studies of the effects of NSAIDs on the functioning of plant mitochondria are relatively scarce, the present work is an important contribution to the elucidation of the mechanism of NSAID toxicity toward non-target plant organisms.

This study looks at the relationship between soil chemical characteristics and nematode communities in Meghalaya's agricultural landscapes. Nematodes, which are important bioindicators of soil health, were studied in connection to soil characteristics such as pH, Electrical Conductivity (EC), Organic Carbon (OC), and nutrient levels (N, P, K) in various parts of Meghalaya. The study found strong relationships between soil chemistry and the spread of various nematode taxa. Acidic soils with lower pH and higher organic carbon were shown to have higher populations of plant-parasitic nematodes such as Meloidogyne sp. and Xiphinema sp., both of which have been shown to reduce agricultural productivity. Soils with greater EC, on the other hand, have fewer of these damaging nematodes, implying that modifying soil salinity could be a viable technique for controlling nematode infestations. Furthermore, nutrient-rich soils, particularly those high in phosphorus and potassium, were associated with larger abundances of Tylenchorhynchus sp., emphasising the intricate relationship between soil fertility and nematode dynamics. The study highlights the critical impact of soil chemical characteristics in influencing nematode communities, as well as the importance of specific soil management strategies to improve crop health in Meghalaya. Farmers can use these findings to build targeted methods for controlling nematode populations, decreasing crop loss and encouraging sustainable agricultural practices in the region. This study offers useful recommendations for enhancing soil health and increasing agricultural productivity in some regions of Meghalaya's agroecosystems.

Authors: Ndlela Sphesihle , Barnes Neil 
Published: August 2024

Aims: According to the SME South Africa study conducted in 2018, the survival rate of South African Small medium enterprises (SME) is low. The country’s policymakers have become increasingly aware of the need to support the cultivation and growth of resilient, innovative and agile entrepreneurs as can be seen in the National Integrated Small Enterprise Development (NISED) Masterplan. In addition, employees in innovative organizations are more likely to share knowledge to contribute to the improvement of organizational performance, as such environments require high levels of innovative activity. Therefore, the study aimed to assess the level of innovative thinking skills among SME owners in South Africa's construction and manufacturing industries and explore its impact on SME longevity.
Study Design: The study employed a descriptive quantitative design, focusing on 204 SME owners from the construction and manufacturing industries in South Africa, selected via quota sampling. Data was collected through an anonymous online questionnaire, which assessed the participants' levels of innovative thinking. The analysis, conducted using Python software, aimed to determine the prevalence of these skills and their implications for the longevity of SMEs.
Place and Duration of Study: The study was conducted in South Africa, focusing on the construction and manufacturing industries. The data collection and analysis took place over a period of two years June 2020 and July 2022.
Methodology: The study employed a descriptive quantitative approach, using quota sampling to select 204 SME owners from the construction and manufacturing industries in South Africa. Data was gathered through an anonymous online questionnaire and analyzed using Python software to assess innovative thinking levels. Python was selected for descriptive statistics due to its robust and mature libraries like Pandas and NumPy, which facilitate efficient data manipulation and analysis. It ensures consistency and reproducibility in research workflows.
Results: The results indicated that SME owners in both the construction and manufacturing sectors exhibited moderate levels of innovative thinking.

Validation of DEM prediction for granular avalanches on irregular terrain
Authors: Mead Stuart R. , Cleary Paul W. 
Published: August 2015

AbstractAccurate numerical simulation can provide crucial information useful for a greater understanding of destructive granular mass movements such as rock avalanches, landslides, and pyroclastic flows. It enables more informed and relatively low cost investigation of significant risk factors, mitigation strategy effectiveness, and sensitivity to initial conditions, material, or soil properties. In this paper, a granular avalanche experiment from the literature is reanalyzed and used as a basis to assess the accuracy of discrete element method (DEM) predictions of avalanche flow. Discrete granular approaches such as DEM simulate the motion and collisions of individual particles and are useful for identifying and investigating the controlling processes within an avalanche. Using a superquadric shape representation, DEM simulations were found to accurately reproduce transient and static features of the avalanche. The effect of material properties on the shape of the avalanche deposit was investigated. The simulated avalanche deposits were found to be sensitive to particle shape and friction, with the particle shape causing the sensitivity to friction to vary. The importance of particle shape, coupled with effect on the sensitivity to friction, highlights the importance of quantifying and including particle shape effects in numerical modeling of granular avalanches.
Lithium‐Salt‐Containing High‐Molecular‐Weight Polystyrene‐block‐Polyethylene Oxide Block Copolymer Films

Published: August 2015

AbstractIonic conductivity in relation to the morphology of lithium‐doped high‐molecular‐weight polystyrene‐block‐polyethylene oxide (PS‐b‐PEO) diblock copolymer films was investigated as solid‐state membranes for lithium‐ion batteries. The tendency of the polyethylene (PEO) block to crystallize was highly suppressed by increasing both the salt‐doping level and the temperature. The PEO crystallites completely vanished at a salt‐doping ratio of Li/EO>0.08, at which the PEO segments were hindered from entering the crystalline unit of the PEO chain. A kinetically trapped lamella morphology of PS‐b‐PEO was observed, due to PEO crystallization. The increase in the lamella spacing with increasing salt concentration was attributed to the conformation of the PEO chain rather than the volume contribution of the salt or the previously reported increase in the effective interaction parameter. Upon loading the salt, the PEO chains changed from a compact/highly folded conformation to an amorphous/expanded‐like conformation. The ionic conductivity was enhanced by amorphization of PEO and thereby the mobility of the PEO blocks increased upon increasing the salt‐doping level.
Influence of FPS bearing properties on the seismic performance of base‐isolated structures
Authors: Castaldo Paolo , Tubaldi Enrico 
Published: August 2015

SummaryThe paper analyzes the influence of friction pendulum system (FPS) isolator properties on the seismic performance of base‐isolated building frames. The behavior of these systems is analyzed by employing a two‐degree‐of‐freedom model accounting for the superstructure flexibility, whereas the FPS isolator behavior is described by adopting a widespread model that considers the variation of the friction coefficient with the velocity. The uncertainty in the seismic input is taken into account by considering a set of natural records with different characteristics scaled to increasing intensity levels. The variation of the statistics of the response parameters relevant to the seismic performance is investigated through the nondimensionalization of the motion equation and an extensive parametric study carried out for different isolator and system properties. The proposed approach allows to explore a wide range of situations while limiting the required nonlinear response history analyses.Two case studies consisting of base‐isolated building frames described as shear‐type systems are finally investigated in order to demonstrate the capabilities of the proposed simplified model in unveiling the essential characteristics of the performance of buildings isolated with FPS bearings.

Published: August 2015

AbstractBee venom (BV) is one of the alternative medicines that have been widely used in the treatment of chronic inflammatory diseases. We previously demonstrated that BV induces immune tolerance by increasing the population of regulatory T cells (Tregs) in immune disorders. However, the major component and how it regulates the immune response have not been elucidated. We investigated whether bee venom phospholipase A2 (bvPLA2) exerts protective effects that are mediated via Tregs in OVA‐induced asthma model. bvPLA2 was administered by intraperitoneal injection into control and OVA‐challenged mice. The Treg population, total and differential bronchoalveolar lavage fluid (BALF) cell count, Th2 cytokines, and lung histological features were assessed. Treg depletion was used to determine the involvement of Treg migration and the reduction of asthmatic symptoms. The CD206‐dependence of bvPLA2‐treated suppression of airway inflammation was evaluated in OVA‐challenged CD206‐/‐ mice. The bvPLA2 treatment induced the Tregs and reduced the infiltration of inflammatory cells into the lung in the OVA‐challenged mice. Th2 cytokines in the bronchoalveolar lavage fluid (BALF) were reduced in bvPLA2‐treated mice. Although bvPLA2 suppressed the number of inflammatory cells after OVA challenge, these effects were not observed in Treg‐depleted mice. In addition, we investigated the involvement of CD206 in bvPLA2‐mediated immune tolerance in OVA‐induced asthma model. We observed a significant reduction in the levels of Th2 cytokines and inflammatory cells in the BALF of bvPLA2‐treated OVA‐induced mice but not in bvPLA2‐treated OVA‐induced CD206‐/‐ mice. These results demonstrated that bvPLA2 can mitigate airway inflammation by the induction of Tregs in an OVA‐induced asthma model.

Published: August 2015

AbstractThe paper uses two rounds of survey to examine the relative returns to micro‐credit for small‐scale businesses in two regions of Ghana. Propensity scores matching and the nearest neighbour matching are used to assess the return to micro‐loans on retail businesses of clients and non‐clients. Micro‐credit impacts on sales, stock, expenses and profit for clients as compared with non‐clients. Women‐owned businesses produce higher returns from micro‐credit than men‐owned businesses. Individual and enterprise characteristics influence access to micro‐credit. The paper offers policy recommendations to microfinance institutions on whom and which business activity to give credit.

Dietary overlap and potential competition in a dynamic ungulate community in Northwestern Canada
Authors: Jung Thomas S. , Stotyn Shannon A. , Czetwertynski Sophie M. 
Published: August 2015

ABSTRACTThe potential for interspecific competition for food resources is a key consideration when newly introduced ungulates occupy a shared range with resident native species. Management plans in Yukon, Canada, for reintroduced bison (Bison bison) and introduced elk (Cervus canadensis) called for an assessment of competition for food resources between these species and resident populations of caribou (Rangifer tarandus), thinhorn sheep (Ovis dalli), and moose (Alces americanus). To assess potential competition among ungulates, we examined dietary overlap of 7 ungulate species in southwestern Yukon, Canada. We compared diet composition at the forage class level and composite diet indices (diversity, evenness, and niche breadth) among species found at 2 elevation classes (high [≥1,200 m ASL] and low [<1,200 m ASL]) during summer and winter, using data derived from microhistological analyses of feces. Composite indices and percent of key forage classes in diets differed among ungulates during summer and winter and at both high and low elevations. Potential dietary overlap for most species pairs was low to moderate (0.07–0.60). However, for bison and thinhorn sheep at high elevations, and bison and semi‐feral horses (Equus ferus caballus) at low elevations, it was high (0.82–0.97) during both summer and winter, indicating potential for food competition. Dietary overlap between species appeared to be based primarily on morphophysiological classification (i.e., browser‐intermediate‐grazer), rather than body size. Bison, horses, and sheep were all grazers. Intermediate species, such as introduced elk, had only moderate dietary overlap with several species. We concluded that the potential for competition for food resources based on dietary overlap between bison and sheep and bison and horses may be high in our study area, depending on forage availability, but for all other species pairs in our study area the potential for forage competition is low to moderate. © 2015 The Wildlife Society.

Published: August 2015

AbstractC. elegans MnSOD‐3 has been implicated in the longevity pathway and its mechanism of catalysis is relevant to the aging process and carcinogenesis. The structures of MnSOD‐3 provide unique crystallographic evidence of a dynamic region of the tetrameric interface (residues 41–54). We have determined the structure of the MnSOD‐3‐azide complex to 1.77‐Å resolution. Analysis of this complex shows that the substrate analog, azide, binds end‐on to the manganese center as a sixth ligand and that it ligates directly to a third and new solvent molecule also positioned within interacting distance to the His30 and Tyr34 residues of the substrate access funnel. This is the first structure of a eukaryotic MnSOD‐azide complex that demonstrates the extended, uninterrupted hydrogen‐bonded network that forms a proton relay incorporating three outer sphere solvent molecules, the substrate analog, the gateway residues, Gln142, and the solvent ligand. This configuration supports the formation and release of the hydrogen peroxide product in agreement with the 5‐6‐5 catalytic mechanism for MnSOD. The high product dissociation constant k4 of MnSOD‐3 reflects low product inhibition making this enzyme efficient even at high levels of superoxide.

AbstractWe compare first-order (refractive) ionospheric effects seen by the MWA with the ionosphere as inferred from GPS data. The first-order ionosphere manifests itself as a bulk position shift of the observed sources across an MWA field of view. These effects can be computed from global ionosphere maps provided by GPS analysis centres, namely the CODE. However, for precision radio astronomy applications, data from local GPS networks needs to be incorporated into ionospheric modelling. For GPS observations, the ionospheric parameters are biased by GPS receiver instrument delays, among other effects, also known as receiver DCBs. The receiver DCBs need to be estimated for any non-CODE GPS station used for ionosphere modelling. In this work, single GPS station-based ionospheric modelling is performed at a time resolution of 10 min. Also the receiver DCBs are estimated for selected Geoscience Australia GPS receivers, located at Murchison Radio Observatory, Yarragadee, Mount Magnet and Wiluna. The ionospheric gradients estimated from GPS are compared with that inferred from MWA. The ionospheric gradients at all the GPS stations show a correlation with the gradients observed with the MWA. The ionosphere estimates obtained using GPS measurements show promise in terms of providing calibration information for the MWA.
