Despite the availability of an effective vaccine for several decades, the measles virus continues to spread worldwide. From 2018 to 2019, several countries experienced large measles outbreaks with genotype B3, including Tunisia. We analyzed 66 samples collected from serologically confirmed measles cases during this outbreak. Fifty-five percent were aged less than 12 months and had not received a measles vaccine. Phylogenetic analysis using the 450 nucleoprotein (N450) window revealed that all strains belonged to genotype B3, with five different variants identified. The N450 sequence of the predominant one, which circulated all through the epidemic period, was identical to the named strain MVs/Kabul.AFG/20.14/3. For better molecular discrimination, the amplification and sequencing of 1018 nucleotides in the non-coding region between the M and F genes (MF-NCRs) revealed higher variability with at least nine clusters. A phylogeographic study using Bayesian methods suggested the Governorate of Kasserine (on the borders of Algeria) as the introduction point with a TMRCA (Time to Most Recent Common Ancestor) for the 2019 sequences estimated around October 2018. These findings emphasize the crucial role of advanced molecular investigations in tracing measles transmission pathways which, together with good vaccine coverage, will help the final success of the global measles elimination program.

The Wadi El-Rayan lakes are important aquatic environments located at the border of the great North African Sahara. Quantifying the temporal changes in these lakes due to natural and/or anthropogenic stressors is critical when assessing potential impacts on aquatic ecosystem health and the sustainability of fisheries. To detect the changes in fish communities and their drivers, the landing composition of the Wadi El-Rayan lakes over the past 30 years was quantitatively analyzed. The areas of the lakes dramatically decreased from 110 km2 in 1991 to 73 km2 in 2019. The loss of the lake area was attributed to climate warming, where the evaporation rate exceeded the volume of recharge and the recharge decreased due to an increase in agriculture and aquaculture. The total landing significantly increased in the past three decades due to an increase in the fishing effort (number of licensed boats). Nile tilapia, mullet, and grass carp dominated the landings. The pelagic-to-demersal ratio indicated a shift in the fish community composition towards demersal species. This shift was attributed to an increase in the eutrophication level. The fish communities of the landing data were clustered into four distinct groups. These clusters were significantly differentiated (p < 0.001) in both a PERMANOVA test and a PCA plot. There was a gradual replacement of the dominant species among these clusters. The most recent cluster (2018–2019) was characterized by rare species dominating the community. This shift in species composition suggests that target taxa may have been overexploited. The total landing also decreased, which may have been a result of climate warming. Furthermore, the presence of alien and warm-water species significantly increased. The fish community structure and composition shift could be attributed to anthropogenic (mismanagement) and natural climatic changes (warming).

Published: September 2024

Adsorption using biochar is a high-efficient method for removing dyes from wastewater, and it has become a hot research topic in recent years. Biochar produced from organic wastes through pyrolysis is a promising way to combine bioenergy recovery and dye removal. In this study, durian shell (DS) was used as a feedstock for biochar and bio-oil production under different pyrolysis temperatures (400, 500, and 600 °C) for bioenergy recovery. Then, the biochar was applied as the absorbent for methylene blue (MB) removal from wastewater under batch and continuous experiments. It was found that the bio-oil production was slightly affected by temperature, while the productivity of biochar decreased from 42.05% to 30.65% with the increase in pyrolysis temperature from 400 to 600 °C. Compared with the biochar produced at 500 °C (DS-500) and 600 °C (DS-600), the biochar obtained at 400 °C (DS-400) exhibited higher MB removal efficiency and adsorption capacity under various pH conditions due to the superior microstructure. A high pH condition was beneficial for the adsorption process with DS-400. Additionally, the MB removal efficiencies increased with the increase in biochar dosage by providing more activated sites. A high MB content can promote the adsorption process, but a too high MB content negatively affects the removal efficiency due to the sorption saturation. Adsorption processes are more likely to match a pseudo-second-order model by chemical reactions. In the long-term continuous experiment, MB can be effectively removed to match the discharge standard by DS-400. This study provided a sustainable pathway for organic waste disposal and dye wastewater treatment.

Published: September 2024

In order to investigate the effects of selenium (Se) against cadmium (Cd) toxicity, 180 healthy grass carp were separated into three groups and fed diets containing 0.147 (control group), 0.562, and 1.044 mg/kg of selenium Yeast throughout 60 days. In grass carp livers, malondialdehyde (MDA) content, antioxidant enzyme activities, and apoptosis-related gene expression were examined. As a result of acute exposure to cadmium, MDA content decreased significantly. With time, catalase (CAT), total superoxide dismutase (T-SOD), and glutathione peroxidase (GSH-Px) activities changed. The relative transcript levels of heavy metal scavenging genes abcc2 and mt2 were significantly reduced. The relative levels of expression of jnk, bax, caspase-3, caspase-8, and caspase-9 in apoptosis-associated factors were significantly elevated after cadmium exposure. Selenium-supplementation downregulated the expression of apoptosis-related factors. As compared to the control group, liver cells supplemented with selenium had a significantly lower apoptotic index. Comprehensive analysis showed that dietary selenium supplementation significantly attenuated cadmium-induced peroxidative damage and apoptosis in liver by increasing GSH-Px activity, and that cadmium toxicity could be alleviated by the addition of yeast selenium.

Published: September 2024

Magnetization constitutes an efficacious physical treatment technique applicable to saline water. The new spiral flow magnetizer, in conjunction with the cyclic magnetization process, has the effect of maximizing effective magnetization time and thereby achieving the optimal magnetization results. Based on this, saline water (0.27, 3, 6, and 10 g L−1) was treated with different levels of magnetization (0, 0.2, 0.4 and 0.6 T), and the effects of magnetized saline water (MSW) drip irrigation on loamy-sand soil moisture, soluble salt infiltration, and redistribution characteristics were studied through a vertical soil column simulation experiment. The results showed that the wetting front migration in MSW drip irrigation experiments exhibited minimal variation during soil water infiltration, and a notable change during redistribution with the experimental duration of 0.27 and 3g L−1 saline water treatments being significantly different (p < 0.05). Treating saline water with different mineralization levels with magnetization demonstrated water retention (0.27 g L−1 excluded) and salt drainage characteristics; calculated soil water storage increased by 1.58–14.19% and salt storage decreased by 0.22–7.66%. The optimal magnetization intensity for low-mineralization (0.27 and 3 g L−1) saline water was 0.2 T and for high-mineralization (6 and 10 g L−1) it was 0.6 T. The adsorption and exchange of cations (19.58–32.12%) by the optimum MSW treatments was greater than that of anions (9.46–14.15%); specifically, the relative exchange capacity of Ca2+ and Mg2+ in cations was more than K+ and Na+, while HCO3− and SO42− in anions was more than Cl−. This study provides theoretical and technical support for the irrigation of farmland with poor-quality water, as well as for the development of magnetized water irrigation technology.
Adsorption of Tricyclazole and 2,4-Dichlorophenoxyacetic Acid onto Biochar Produced from Anaerobically Digested Sludge
Authors: Wang Fen , Hou Yingjian
Published: September 2024

Anaerobically digested sludge-derived biochar was produced through pyrolysis at 700 °C, called BC700. BC700 was characterized using a scanning electron microscope (SEM), X-ray diffractometer (XRD), Fourier-transform infrared spectroscopy (FTIR), and the Brunauer–Emmett–Teller (BET) method. The factors influencing the adsorption process and the mechanism involved in adsorbing tricyclazole and 2,4-D in single and binary systems were revealed. The theoretical maximum adsorption capacities of BC700 for tricyclazole and 2,4-D in a single system were 11.86 mg/g and 7.89 mg/g, respectively. In the binary system, the theoretical saturated adsorptive capacities of tricyclazole and 2,4-D were 5.27 mg/g and 3.20 mg/g, respectively. The adsorption of tricyclazole and 2,4-D by BC700, whether in single or binary systems, matched closely with the Freundlich isotherm and the pseudo-second-order model. This study indicates that anaerobically digested sludge-derived biochar is potentially valuable for removing pesticide contamination in surface water.

Heavy metal pollution is a critical issue affecting the safety of drinking water sources. However, the impact of human activities on heavy metal risk levels in water-carrying lakes remains unclear. This study aims to explore the risk mechanisms of heavy metals in Luoma Lake, an important water-carrying lake for the South-to-North Water Diversion Project. We explored the spatial and temporal differences in the distribution of heavy metals in Lake Luoma using methods such as the heavy metal pollution index (HPI) and assessed the risk variations using a health assessment model. The results indicated that heavy metal concentrations in water-carrying lakes generally decreased during the dry season, with Mn and Zn levels decreasing by 89.3% and 56.2%, respectively. The comprehensive score of HPI decreased by 13.16% following the retreating polder compared to the control area (Non-retreating polder area). Furthermore, the HPI at the drinking water intake was lower, which is closely associated with the elevated dissolved oxygen (DO) and oxidation–reduction potential (ORP) resulting from water diversion. The annual average health risk across the entire lake was not significant, with higher levels observed in the control area. The annual non-carcinogenic risk levels of Mn, Ni, Cu, Zn, and Pb range from 10−13 to 10−9, which are considered negligible risk levels. Notably, the carcinogenic risk posed by arsenic (As) through the drinking pathway reached 10−5 a−1, exceeding the maximum levels recommended by certain organizations. These findings provide a critical foundation for managing heavy metals in water-carrying drinking water sources.

Published: September 2024

The precipitation gradient (PG) is a crucial parameter for watershed hydrological models. Analysis of daily precipitation and elevation data from 30 stations in the southeastern Tibetan Plateau (SETP) during the active phase of the Indian monsoon reveals distinct patterns. Below 3000 m, precipitation generally decreases with increasing altitude. Between 3000 and 4000 m, precipitation patterns are more complex; in western regions, precipitation increases with elevation, whereas in eastern regions, it decreases. Above 4000 m, up to the highest observation point of 4841 m, precipitation continues to decrease with elevation, with a more pronounced decline beyond a critical height. In the SETP, PGs for LYR and NYR are positive, at 11.3 ± 2.7 mm/100 m and 17.3 ± 3.8 mm/100 m, respectively. Conversely, PLZB exhibits a negative PG of −22.3 ± 4.2 mm/100 m. The Yarlung Zangbo River (YLZBR) water vapor channel plays a significant role in these PGs, with the direction and flux of water vapor potentially influencing both the direction and magnitude of the PG. Additional factors such as precipitation intensity, the number of precipitation days, precipitation frequency, and station selection also significantly impact the PG. Notable correlations between elevation and variables such as the number of precipitation days, non-precipitation days, and precipitation intensity. The precipitation intensity gradients (PIGs) are 0.06 ± 0.02 mm/d/100 m, 0.11 ± 0.04 mm/d/100 m, and −0.18 ± 0.04 mm/d/100 m for the three catchments, respectively. Future research should incorporate remote sensing data and expand site networks, particularly in regions above 5000 m, to enhance the accuracy of precipitation–elevation relationship assessments, providing more reliable data for water resource simulation and disaster warning.

Published: September 2024

Background

The use and advantages of point-of-care tests (POCTs) for C-reactive protein (CRP) in general practice, especially for upper respiratory tract infections (uRTIs), have been studied extensively. However, there is limited knowledge about test indications, prerequisites, and integration of these tests into everyday practice.

Aim

This study aims to investigate the attitudes and experiences of general practitioners (GPs) in Germany regarding the use of semi-quantitative CRP-POCTs. The study places special emphasis on implementation in routine care, including testing procedures, feasibility, opportunities and barriers for specific consultation scenarios, as well as test indications and their impact on GP-patient communication.

Design & setting

Qualitative interview study with 10 GPs (May/2023 to Aug/2023)

Method

Ten German GPs who participated in an observational study on CRP-POCT use in general practices were interviewed using semi-structured interviews. Audio recordings were transcribed and content analysis was performed.

Results

Interviewed GPs stated that CRP-POCTs offer several advantages for various treatment cases. They improve diagnostic confidence and certainty of GPs’ therapeutic decisions, and offer a broad spectrum of indications and application scenarios. Additionally, they have a positive impact on GP-patient communication, and their ease of use enables rapid implementation into existing workflows. On the other hand, CRP-POCT increase the time required for test performance and patient consultation.

Conclusion

Due to the numerous benefits of semi-quantitative CRP-POCTs, interviewed GPs have a favourable attitude towards their regular integration into everyday practice. Implementation barriers include increased time and personnel expenses for testing and inadequate reimbursement by German statutory health insurance.

Curved Text Detection in Scenic Images via Proposal-Free Panoptic Segmentation and Deep Learning
Authors: Chhabra Prachi , Abidi Ali
Published: September 2024

Curved texts pose a significant challenge in detection in ‘the wild’, primarily due to the inherent variabilities in text orientation and possible distortions while the images are being acquired. Standard text detection models have been observed to exhibit low accuracy in detecting texts on curved surfaces. To fill this gap, there have been a variety of deep learning-based models proposed to date which have achieved low to moderate success. This paper implements a DL-based model for the detection and recognition of text from scenic images. The proposed approach applies different image processing techniques such as Gray scale conversion, noise removal using median filter, normalization and Otsu’s Binarization and a panoptic segmentation technique for achieving desired text detection performance. A synthetic dataset is created which is used to fill in the gaps of character annotation and multi-orientation. The performance of the proposed approach is determined using different evaluation metrics and the results are compared against existing techniques such as You Only Look Once version 5 (YOLOv5), HDBNet, Bidirectional Perspective Network (BiP-Net), and Res18-LVT. Results show that the proposed approach achieves better performance in terms of precision (98.7%), recall (91.7%), and F1 score (94.5%) as compared to existing classification models.

Authors: Wu Yuebo , Chu Shiwei , Bao Huifang , Wang Duansong , Zhou Jian
Published: September 2024

This study presents an innovative image encryption algorithm anchored on the two-dimensional Logistic chaotic system, designed to address the limitations of traditional methods in terms of speed and security. The algorithm employs pixel shifting and scrambling, coupled with a segmented grayscale value substitution, to achieve a high level of security with strong key sensitivity and robust resistance to both differential and statistical attacks. Experimental validation demonstrates its superiority with fast encryption speeds, as evidenced by an encryption time of 0.2136 seconds for a 256×256 color image, and an entropy close to its ideal value, indicating excellent randomness. This method also exhibits high performance in resisting differential attacks, with Number of Pixels Change Rate (NPCR) and the Unified Average Changing Intensity (UACI) values nearing their optimal expected values. The integration of Quantum Key Distribution (QKD) is suggested for future work to enhance security against quantum computing threats, solidifying the algorithm’s potential as a leading solution for the image encryption.

Published: September 2024

Background: Weight bias internalization (WBI) is a serious challenge because of its negative impact on psychological consequences. Although the cognitive-behavioral intervention has been applied to reduce WBI, little is known about its effectiveness among Thai obese youth. Thus, this study sought to determine the effects of a cognitive-behavioral group counseling (CBGC) program on WBI and psychological outcomes in obese youths. Study Design: A randomized controlled trial. Methods: Eighty obese youths were randomly allocated to two intervention (n=40) and control (n=40) groups. The intervention group received a CBGC program in three sessions with ten activities, while the control group performed their usual counseling process. Data were collected through standardized interviewers with a structured interview questionnaire. The chi-square test, independent samples t-test, Mann-Whitney U test, repeated measure ANOVA, and multivariate linear regression were applied for data analyses. Results: At the follow-up visit, the intervention group had a significant decrease in the mean of WBI, depression, and perceived stress and an increased mean of self-esteem compared to the control group. After adjusting baseline characteristics and baseline outcome values, the intervention also significantly improved WBI (B=-6.82, P<0.001), depression (B=-4.17, P<0.001), perceived stress (B=-6.01, P<0.001), and self-esteem (B=5.07, P<0.001). Conclusion: The CBGC program effectively reduced WBI, depression, and perceived stress while improving self-esteem among obese youths. This study recommends that group counseling programs be employed as part of a counseling process for obese youth who have experienced WBI.

Authors: Noviati Nuraini Diah , Munawarah Muthiah , Amir Trisia Lusiana , Febiola Tania
Published: September 2024

This study aims to examine the relationship between Body Mass Index (BMI) and urinary incontinence in the elderly, a significant but often neglected public health concern. A cross-sectional design was used, involving elderly residents of Wisma Mulia Nursing Home. Urinary incontinence was measured using the International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF), and BMI was calculated using a standard formula. Statistical analysis with Pearson’s correlation revealed a significant association between BMI and urinary incontinence (p < 0.05), with an average ICIQ-SF score of 16.00 and a standard deviation of 10.30. These findings suggest that BMI is a contributing factor to the severity of urinary incontinence in the elderly. Clinically, the results emphasize the importance of considering BMI in the assessment and management of urinary incontinence. Interventions focusing on BMI reduction, including diet and exercise, could improve the quality of life for older adults. This aligns with the third Sustainable Development Goal (SDG), promoting good health and well-being. Future research with larger sample sizes, and exploration of factors such as physical activity and comorbidities, is essential. Longitudinal studies tracking BMI changes over time and their impact on urinary incontinence would provide deeper insights for effective interventions.
Effect of Fragmentation as A Moderation on The Relationship Between Supply Chain Management And Project Performance
Authors: Heri Heri Yanto Ndraha
Published: September 2024

Project fragmentation can be understood as breaking down the construction work into several parts due to the complexity and massive scale of a project. Initially, this division was intended to focus work on specific sectors, ensuring precision, speed, and guaranteeing Project Performance. However, high levels of fragmentation can result in a lack of integration between parts of the project, which can adversely affect both the implementation process and the final outcome of the project. One such adverse effect is project delay, which can diminish project performance, as seen in the X PEB steel construction project. Previous studies have identified an approach to improve project quality through the implementation of supply chain management (SCM). Therefore, this study examines the impact of fragmentation on SCM concerning project performance, comparing the effect of SCM on performance under conditions of high fragmentation versus when fragmentation is disregarded in the PEB steel construction project. The results show that SCM influences performance by 51%. This analysis indicates that SCM plays a crucial role in achieving the performance of PEB steel construction projects. When project fragmentation is assumed to be non-existent, SCM's influence on project performance is even greater, reaching 82%, indicating that SCM has a significant impact on project performance and serves as a solution to maintaining project performance. This study concludes that fragmentation serves as a moderating variable affecting project performance in PEB steel construction.
Mathematical Model for Multi Depot Simultaneously Pick Up and Delivery Vehicle Routing Problem with Stochastic Pick Up Demand
Authors: Desticioğlu Taşdemir Beste , Özyörük Bahar
Published: September 2024

In a classical vehicle routing problem (VRP), customer demands are known with certainty. On the other hand, in real-life problems, customer demands may change over time. Therefore, in the classical VRP, the assumption that customer demands are stochastic should be taken into account. To expedite consumer demands and minimize fuel use and carbon emissions, organizations must concurrently address client distribution and collection requirements. Customers' distribution requirements can be predicted, but it is impossible to predict in advance the product requirements they will send for recycling. Hence, in this study, a mathematical programming model is developed for the multi-depot simultaneous pick-up and delivery vehicle routing problem under the assumption that customers' picking demands are stochastic. However, there are non-linear constraints in the developed model. Thereby, firstly, the stochastic model is linearized, and then the effectiveness of the model is analyzed. The efficacy of the linearized model is ascertained by generating test problems. The study investigated the impact of varying reliability levels and the number of depots on the model. As a result of the sensitivity analysis, it was determined that by decreasing the reliability level, the solution time of the problems decreased and the number of problems reaching the best solution increased. In the study, 135 test problems were solved by changing the reliability level, and the best result was achieved in 105 of these problems within 7200 s. The increase in the number of depots both reduced the solution time of the problems and was effective in reaching the best solution for all solved test problems.

Представлено результати дослідження властивостей плівок політетрафторетилену (ПТФЕ) та поліпарафенілен сульфіду (ППС), які були наповнені молекулами барвників за допомогою співосадження у вакуумі. Досліджено тонкі полімерні плівки, що наповнені різними поліметиновими барвниками з різними концентраціями. Властивості плівок при кімнатній температурі і під час нагрівання було вивчено з використанням оптичної абсорбційної спектроскопії. Показано, що полімерна матриця запобігає агрегації молекул барвника, зокрема ПТФЕ-матриця запобігає агрегації сильніше ніж ППС-матриця. Протягом нагрівання ПТФЕ-матриця утримує молекули барвника в неагрегованому стані до температури розкладання барвника.

In the current context where all sectors aim to promote sustainable development, hospitals, as large organizations with significant human interactions, face challenges in managing not only medical waste but also general waste such as water bottles. Improper management of these wastes can lead to environmental problems and high disposal costs. This study performed a life cycle assessment (LCA) of regular (petroleum-based) and alternative (bio-based) polyethylene terephthalate (PET) bottles used in Ramathibodi Hospital, Thailand, to identify effective strategies for mitigating environmental impacts. The assessment was divided into three scenarios: label-free bottles, bio-based bottles, and 100% recycling. The results indicate that using label-free bottles instead of conventional ones merely reduces environmental impacts by 2%. Transitioning to 30% and 100% bio-based PET can decrease greenhouse gas (GHG) emissions by 7 and 13 tons of CO2 eq per year, respectively. Currently, the hospital's PET bottles contribute 56.2 tons of CO2 eq annually. Health impacts associated with conventional PET bottles amount to 11.70 disability-adjusted life years (DALYs), a comprehensive measure that includes both mortality and morbidity. Meanwhile, 30% and 100% bio-based bottles reduce this to 7.35 and 4.87 DALYs, respectively. Achieving 100% recyclability in bottle management can cut GHG emissions from disposal processes by up to 90%. Moreover, combining the use of 100% bio-based PET bottles with 100% recycling can lower GHG emissions by up to 40% compared to current practices. These findings highlight the potential for significant environmental and health benefits through improved bottled water management strategies in hospitals.

Agriculture is vital to Sumbawa Regency's economy, with key activities such as rice cultivation, corn production, onion farming, and cattle rearing. This study applies artificial neural networks (ANN) to predict land cover changes, focusing on agricultural land expansion. Using land cover datasets from ESRI, digital elevation model, and topographical maps, we analyzed land cover changes from 2017 to 2023 and generated future projections for 2050 with the MOLUSCE plugin in qGIS. The predictive model achieved an 85% accuracy rate when comparing 2023 actual data with predictions. Results indicate a significant increase in agricultural land cover by 2050. The key finding is that over a long-term period, the simulation of land use and land cover (LULC) change in Sumbawa reveals an increase of crop areas in the Lunyuk and Labangka Districts. This study highlights the effectiveness of ANN in land cover prediction and emphasizes the need for sustainable practices to balance agricultural expansion. AI-driven insights can aid policymakers in opti-mizing resource allocation and ensuring long-term environmental and economic stability in Sumbawa Regency. Future research should refine models and incorporate additional factors for improved accuracy.
Stimulation of Auditory Perception in Children Using Maria Montessori’s Developmental Materials
Authors: Utrata Magda
Published: September 2024

Auditory perception is an important area of a child’s cognitive development because it determines the development of speech and influences writing and reading skills. Irena Polewczyk defines it as “active reception of auditory stimuli scattered around a person, based on the ability to differentiate speech sounds and their analysis, synthesis and interpretation in accordance with the knowledge, memory and experience that a person has” (Polewczyk, 2017, p. 149). The human body is adapted to receive impressions from the outside world; it segregates, processes and interprets them in the mind. In this way, a person acquires experiences that determine the development of subsequent, more and more precise skills. In the process of developing auditory perception, an important role is played by the child’s immediate environment, which, through appropriate interactions, influences the process of shaping auditory functions. The aim of this article is to present theoretical assumptions regarding the development of auditory perception and the possibilities of stimulating auditory development through the use of Maria Montessori’s teaching aids. The first part of the article describes the development of auditory perception in children. Then, theoretical assumptions regarding Montessori development aids and the possibility of using them in developing auditory skills are presented.
HUMMINGBIRD STRUCTURE OF SOUTHEAST SASKATCHEWAN
Authors: Smith David G. , Pullen Jack R.
Published: September 2024

Saskatchewan’s first Devonian oil pool was discovered September, 1966 at Hummingbird, 45 mi southwest of Weyburn, Saskatchewan. The Hummingbird structure, located on the northwest flank of the Williston basin, is domal in nature and covers approximately 1 sq mi. Oil production is from two zones. The Ratcliffe Member of the Mississippian Charles Formation produces from an average of 49 ft in an algal and bioclastic limestone. The Devonian Birdbear Formation produces from an average of 56 ft in a fine-crystalline, vuggy dolomite.

The Hummingbird structure is not diastrophic in nature. Rather, it is a sedimentary structure resulting from multiple-stage salt solution and collapse. Recurring local solution of Middle Devonian Prairie Evaporite salt during Late Devonian and Early Mississippian time resulted in collapse of overlying strata and deposition of compensating thicknesses of Souris River, Duperow and Bakken sediments. Between Mississippian and Cretaceous time, solution of Prairie Evaporite salt in the surrounding area caused collapse of all post-Prairie Evaporite beds. The extra Souris River, Duperow and Bakken strata at Hummingbird created the structure. Vertical migration of formation waters along a high-angle fault is suggested as the cause of the local salt solution at Hummingbird.
