Embodied sociotechnical imaginaries: how donor-conceived people imagine identity, family and reprodigital futures beyond regulation

Sociological scholarship has begun to explore imaginaries of family and reproduction, yet less work has focused on the emerging social form of the donor family. In this article, we consider the embodied sociotechnical imaginaries of donor-conceived people, exploring their reflections, judgements, hopes, and predictions regarding donor conception. Combining reflexive thematic analysis of free-text survey responses from sperm donor-conceived (n = 90) and egg donor-conceived (n = 1) and data from semi-structured interviews with sperm donor-conceived people (n = 28), conceived in both clinical and non-clinical contexts in Australia, we analyse donor-conceived people's imaginings of family, identity, and the practice of donor conception in the digital age. Our analysis centres the donor-conceived body that imagines, and in doing so, highlights the entanglements of reproductive and digital technologies, and the humans and institutions that drive their uptake. We argue that leveraging the imaginative and political capacities of donor-conceived people is a productive approach that illuminates possible (re)directions of the assisted reproduction industry as well as illustrating potential policy futures.
Nitrogen concentrations simulated with HBV-N: New response function and calibration strategy

HBV-N is a conceptual process-based model for simulation of transformation and transport of nitrogen on the catchment scale. This paper presents further development with focus on the response function and calibration procedures. Evaluation of the model routines was made in 12 test basins in southern Sweden (without or with only few lakes). Previous versions of HBV-N included a HBV version with a single reservoir in the response function. The presented results show that both nitrogen concentrations and water discharge simulations improved when a second reservoir was introduced. The two-reservoir model was found to be more well-posed for description of residence-times and flow paths. On average, this resulted in an increase in explained variance (R 2 ) for nitrogen concentrations by 0.3. Multiple-response split-sample calibration was found to further improve the model performance and reliability. In previous applications HBV-N has been applied by using single-response calibration. However, simultaneous calibration of water discharge and nitrogen improved the R 2 for nitrogen concentrations by about 0.1 (range 0.02-0.25), but did not affect the simulation of water discharge. This new calibration strategy forces the hydrological parameters to a new optimum, and reduces the level of uncertainty for both hydrochemical and hydrological modelling.
Dynamical Behavior of Nonlinear Coupled Reaction-Diffusion Model: A Numerical Study Utilizing ADI and Staggered Grid Finite Volume Method in Matlab

In this research, we present two Numerical algorithms for studying the dynamics of spatially extended coupled nonlinear reaction-diffusion model. The difference in this work is to model a system of reacting and diffusing chemicals, and how to predict the dynamics of ecologically relevant behavior, including chaos. The goal can be achieved by applying a proposed staggered grid finite volume method for solving the Reaction model, rigorously validating the numerical method and grid generation techniques against established results. Additionally, we integrate an Alternating Direction Implicit formulation to compare the efficiency and accuracy of the model’s results. Dynamical system analysis, including linear stability analysis, is applied to comprehend the fundamental qualitative features of the inhibitor-activator system inherent in the coupled reaction-diffusion equations. Results, presented in tables and graphical representations, show that the schemes’ high accuracy at fourth-order precision in space and second-order in time, with conditional stability. Numerical results showed that the proposed finite volume approach was exceptionally proficient and accurate for tackling the two-dimensional nonlinear coupled reaction-diffusion model. Overall, the dialog highlights the significance of the proposed staggered grid finite approach and calculations for fathoming coupled reaction-diffusion equations are widely studied in biological and chemical systems of nonlinear differential equations.
Efficacy and Differential Physiological–Biochemical Response of Biostimulants in Green Beans Subjected to Moderate and Severe Water Stress

Water stress is one of the main factors affecting the development of agricultural crops. An innovative alternative to improve tolerance to water stress is the application of biostimulants. In the present study, the efficacy and physiological and biochemical responses of different biostimulants were evaluated in beans under moderate and severe stress. The treatments consisted of three types of irrigation: FC100, without water stress; FC75, irrigation reduced by 25% (moderate water stress); and FC50, irrigation reduced by 50% (severe water stress). In the treatments with water deficits, foliar biostimulants were applied: zinc oxide nanoparticles plus chitosan, Codasil®, Osmoplant®, Stimplex® and salicylic acid. Foliar application of ZnO + chitosan nanoparticles benefited biomass accumulation and yield under moderate water stress (FC75) and Codasil® and Osmoplant® under severe water stress (FC50). Proline, free sugars and gas exchange were higher with the application of ZnO + chitosan nanoparticles under moderate water stress and with Codasil® and Osmoplant® under severe water stress. Depending on the severity of water stress, ZnO + chitosan nanoparticles, Codasil® and Osmoplant® are viable products to increase tolerance in green bean cv. Strike plants.
Correlation Analysis of Mackenzie River Discharge and NDVI Relationship

Abstract. This study, based on the analyses of long-term discharge and Normalized Difference Vegetation Index (NDVI) data, revealed a strong seasonal consistency between NDVI and discharge over the Mackenzie River Basin in Canada. The flow–NDVI association is particularly strong in the early growing season (May to the 1st half of June). During this period, discharge rapidly rises and reaches the peak, whereas NDVI increases around the 1st half of May and reaches the maximum at the 2nd half of July. In the mid- and late summer, both discharge and NDVI decline gradually. Correlation analyses identify 2 sensitive periods, i.e., May to June and the 2nd half of July to the 1st half of September, when NDVI significantly responds to discharge variations. In the first period, the half-month NDVI highly correlates to the 1st half of May discharge, indicating that spring flow has a strong influence on vegetation growth in the early growing season. Spatially, almost all of the basin shows a high correlation, except Mackenzie and the Rocky Mountains and the region near the eastern edge of the basin. For the 2nd period, from the 2nd half of July to the 1st half of September, the NDVI relates closely to discharge with lags of 0–5 half-months. Trends analyses suggest river discharge increased during 1982 to 2006 in most seasons except summer. The NDVI trends during the growing season (May to September) clearly correspond to discharge changes. Examination of extreme flow years and corresponding NDVI conditions over the basin also reveal that a lower runoff was associated with a lower basin NDVI with an earlier maximum, whereas the higher flow was linked with a higher NDVI and a longer growing season.
“Knowing I Had Someone to Turn to Was a Great Feeling”: Mentoring Rural-Appalachian STEM Students

Post-secondary students benefit from mentorships, which provide both emotional and academic support tailored to the unique challenges they face. STEM students, and, in particular, those with historically marginalized identities, have unique strengths and face distinct barriers that can be ameliorated by careful, knowledgeable, and well-situated mentoring relationships. With that in mind, we conducted a narrative case study with 10 rural-Appalachian STEM majors enrolled in an NSF-funded mentoring program, intending to collect stories of their impactful experiences with their mentors. We utilized the narrative reconstruction process, and, in so doing, identified five major themes related to the importance of mentor assignment and the impact of mentors’ characteristics and skills related to empathy, consistency, active listening, and teaching. We situate our findings within the existing literature and provide implications for scholars and practitioners who work with mentoring programs dedicated to working with Appalachian communities.

Susceptibility and Synergistic Effects of Guava Plant Extract and Antimicrobial Drugs on Escherichia coli

Introduction Psidium guajava (guava) is a fruit plant of the Myrtaceae family. Guava roots, leaves, and fruits have traditionally been used to prevent and treat various infections. In the last few decades, there has been exponential growth in herbal medicine. Therefore, the present study was conducted to determine the susceptibility and synergistic properties of the antimicrobial activity of the aqueous leaf extract of guava and other antimicrobial drugs against Escherichia coli (E. coli). Methodology A prospective observational study was conducted at the Department of Microbiology, MGM Medical College and Hospital, Navi Mumbai, India, involving 180 urine samples collected from patients who exhibited symptoms of urinary tract infection (UTI). The aim was to evaluate in vitro synergism between leaf extracts of guava and antimicrobial drugs on uropathogenic E. coli, using minimal inhibitory concentration (MIC) and the Kirby-Bauer method. The Kirby-Bauer disc diffusion method was employed to determine the synergistic activity using Muller-Hinton agar (MHA), and the zone of inhibition was measured in millimeters. Results The study found that, of the 180 urine samples collected from patients with UTI, significant growth was observed in 93 samples, with the most notable increase seen in E. coli. The antibiotics tobramycin, ofloxacin, and amikacin, each showing a sensitivity of 76% and 70% respectively, were found to be the most sensitive. Conversely, cefuroxime and cephalothin, both at 76%, were the most resistant. Furthermore, the antibiotic sensitivity pattern of E. coli without guava extract demonstrated tobramycin (TOB) at 76.66%, followed by ofloxacin (OF) and amikacin (AK) at 70% each, levofloxacin (LE) at 63.33%, nitrofurantoin (NIT) at 53.33%, trimethoprim (TR) at 43.33%, cefotaxime (CTX) at 36.66%, ceftizoxime (CZX) at 30%, norfloxacin (NR) at 26.66%, cephalothin (CEP) at 23.33%, amoxicillin-clavulanate (AMC) at 20%, and cefuroxime (CXM) at 10%. In contrast, when the antibiotic sensitivity pattern of E. coli with guava extract was examined, the highest sensitivity was noted for OF (100%), followed by LE (96.66%), TOB (93.33%), AK (90%), NIT (76.66%), AMC and TR (66.66% each), CTX (60%), CZX (53.33%), CEP (50%), NX (43.33%), and CXM (26.66%). Therefore, Psidium guajava (guava) extract exhibited a synergistic effect when combined with antibiotics, most notably with ofloxacin. Conclusion The study revealed that the highest synergistic activity of guava plant leaf extract was with the antibiotic ofloxacin. This finding indicates that guava extract enhances the effectiveness of commonly used antibiotics for treating UTI, an effect mainly attributed to the flavonoid compounds and their derivatives in the guava leaf extract, which inhibit bacterial growth. This study demonstrated the antibacterial properties of guava, suggesting that combining antibiotics with guava extract can help delay the emergence of bacterial resistance.
A Review of Cybersecurity Challenges in Small Business: The Imperative for a Future Governance Framework

Technological shifts—coupled with infrastructure, techniques, and applications for big data—have created many new opportunities, business models, and industry expansion that benefit entrepreneurs. At the same time, however, entrepreneurs are often unprepared for cybersecurity needs—and the policymakers, industry, and nonprofit groups that support them also face technological and knowledge constraints in keeping up with their needs. To improve the ability of entrepreneurship research to understand, identify, and ultimately help address cybersecurity challenges, we conduct a literature review on the state of cybersecurity. The research highlights the necessity for additional investigation to aid small businesses in securing their confidential data and client information from cyber threats, thereby preventing the potential shutdown of the business.
Kick-Starting Wound Healing: A Review of Pro-Healing Drugs

Cutaneous wound healing consists of four stages: hemostasis, inflammation, proliferation/repair, and remodeling. While healthy wounds normally heal in four to six weeks, a variety of underlying medical conditions can impair the progression through the stages of wound healing, resulting in the development of chronic, non-healing wounds. Great progress has been made in developing wound dressings and improving surgical techniques, yet challenges remain in finding effective therapeutics that directly promote healing. This review examines the current understanding of the pro-healing effects of targeted pharmaceuticals, re-purposed drugs, natural products, and cell-based therapies on the various cell types present in normal and chronic wounds. Overall, despite several promising studies, there remains only one therapeutic approved by the United States Food and Drug Administration (FDA), Becaplermin, shown to significantly improve wound closure in the clinic. This highlights the need for new approaches aimed at understanding and targeting the underlying mechanisms impeding wound closure and moving the field from the management of chronic wounds towards resolving wounds.
The camel chains in East Africa- Importance of gaps between the data and the apparent reality

The 11.8 million head of camel counted in East Africa account for 62% of the 2006 world camel population. Less than 4.75% of this stock is slaughtered for national consumption purposes. The official statistics report that annual exports did not exceed 41 thousand heads. This study attempts to examine the following issues: Firstly, how to understand the gaps between the live capital and its economic development through the markets and secondly whether the socioeconomic functions within the pastoral systems sufficiently explain these gaps. The cross-sectional data analysis between different sources revealed significant gaps. For example, the formal market was around 5,030 heads from Djibouti, Ethiopia and Somalia while the official data of exportation from the Berbera and Bossasso Ports registered 7,636 heads in 2004. However, according to the estimation of holding areas capacities in Ethiopia, around 57,000 camels could be exported. From a personal survey conducted in 2007 in the Somalian region of Ethiopia, exportations from said region are estimated to be around 37,000 heads with a profit margin for exporters ranging between 22 to 33 USD per head. At the regional level, official exportations would represent 10% of potential exportations. This range of various gaps that have emerged from different sources of data and from the differences between the collected data and the apparent reality raise a number of questions relating to the economic development of camels. Furthermore, the lack of reliable data on camel activity may explain why camels are often viewed almost as a myth of the pastoral area despite the reality being quite different. (Resume d'auteur)
Haptic Feedback Wristband for Tactile Graphics Reader

Traditionally, blind and visually impaired (BVI) readers face challenges in interpreting tactile graphics due to the need for specialized skills, training, and often external assistance. Existing audio feedback systems also present limitations, including susceptibility to surrounding noise and imprecise guidance. Therefore, this paper presents the design of an assistive device for tactile graphics reader using a haptic feedback system. This device takes the form of a digital watch with an adjustable strap, ensuring compatibility with various wrist sizes. It incorporates four strategically placed vibrating mini-motor discs that deliver directional signals to the user's hand through precise vibrations, guiding their exploration towards the area of interest on the tactile graphic. Pilot testing involving blindfolded sighted readers was conducted to assess the effectiveness of this haptic feedback wristband. The results of the testing revealed that participants could successfully discern direction cues and distinguish varying levels of vibration intensity. Notably, the success rates exceeded 70% for navigation and 85% for vibration intensity recognition.
Heliolitine corals of the upper Douro Formation (Upper Silurian), Canadian Arctic Islands

Heliolitine corals are closely associated with lithistid sponge-dominated reef mounds in Ludlow carbonate ramp facies on Somerset Island. The corals occur abundantly in argillaceous, fossiliferous wackestone immediately flanking and capping the reef mounds, less commonly in calcilutite mudstone within the reef mounds, and with sharply decreasing abundance in nodular argillaceous wackestone to mudstone away from the reef mounds. Exhaustive field collection, and systematic study that included biometric analysis of collected assemblages, indicates that ten heliolitine species are present, including the new species Heliolites furyi, H. garnieri, and H. greineri, and two unidentified species, Heliolites sp. A, and Podollites? sp. The occurrence of H. subdecipiens Klaamann, 1984, H. tchernyshevi Bondarenko, 1966, H. cf. H. rariformis Tchi, 1976, Stelliporella cf. S. podolica Bondarenko, 1971, and Squameolites anomalus Tchi, 1976 indicates an affinity with Eurasian rather than North American faunas of equivalent age. Many new species have been ascribed to Stelliporella since the mid-1970s; most lack the diagnostic axial structures of the genus and are more appropriately regarded as belonging to Heliolites. Newly defined structures termed septal florets occur commonly in H. garnieri and very rarely in three other species of Heliolites. Effective taxonomic use of septal development requires very careful study because of the degree of intraspecific and intracolony variation in some species.
Green facades support biodiversity in urban environment – A case study from Poland

: Green walls, along with green roofs, parks, and vertical gardens, belong to the green infrastructure of cities, which will encompass the majority of humanity in the coming decades. Green infrastructure benefits both urban residents and nature in the urban landscape, although there is no scientific consensus on the extent to which green walls, especially green facades, impact biodiversity in cities. This study examined the influence of green facades on the richness of mammals, birds, and invertebrates, considering the species and age of the plants comprising the green facade in a medium-sized city located in southwestern Poland. It was found that the implementation of green facades significantly enhances species’ biodiversity compared to non-vegetated walls. Four synanthropic bird species were nesting on green facades: Eurasian collared dove ( Streptopelia decaocto ), blackbird ( Turdus merula ), house sparrow ( Passer domesticus ) and woodpigeon ( Columba palumbus ). For the beech marten ( Martes foina ), the green facades are a hunting ground for birds and their eggs. This simple and effective method of creating green walls provides benefits to local wildlife by creating habitats, shelter, and foraging opportunities for selected species. However, it is difficult to determine whether green facades contribute to the formation of ecological corridors in urban environments. The study also examined the social aspect related to the establishment and maintenance of green facades on the surveyed buildings.
Microbial functional diversity alters the structure and sensitivity of oxygen deficient zones

Oxygen deficient zones (ODZs) below the ocean surface regulate marine productivity by removing bioavailable nitrogen (N). A complex microbial community mediates N loss, but the interplay of its diverse metabolisms is poorly understood. We present an ecosystem model of the North Pacific ODZ that reproduces observed chemical distributions yet predicts different ODZ structure, rates, and climatic sensitivity compared to traditional geochemical models. An emergent lower O2 limit for aerobic nitrification lies below the upper O2 threshold for anaerobic denitrification, creating a zone of microbial coexistence that causes a larger ODZ but slower total rates of N loss. The O2‐dependent competition for the intermediate nitrite produces gradients in its oxidation versus reduction, anammox versus heterotrophic denitrification, and the net ecological stoichiometry of N loss. The latter effect implies that an externally driven ODZ expansion should favor communities that more efficiently remove N, increasing the sensitivity of the N cycle to climate change.
