Evaluation of the lithium resource in the Smackover Formation brines of southern Arkansas using machine learning.

Global demand for lithium, the primary component of lithium-ion batteries, greatly exceeds known supplies, and this imbalance is expected to increase as the world transitions away from fossil fuel energy sources. High concentrations of lithium in brines have been observed in the Smackover Formation in southern Arkansas (>400 milligrams per liter). We used published and newly collected brine lithium concentration data to train a random forest machine-learning model using geologic, geochemical, and temperature explanatory variables and create a map of predicted lithium concentrations in Smackover Formation brines across southern Arkansas. Using these predicted lithium maps with reservoir parameters and geologic information, we calculated that there are 5.1 to 19 million tons of lithium in Smackover Formation brines in southern Arkansas, which represents 35 to 136% of the current US lithium resource estimate. Based on these calculations, in 2022, 5000 tons of dissolved lithium were brought to the surface within brines as waste streams of the oil, gas, and bromine industries.

Effects of Mela Organics' New Liquid Fertilizer on Tomato Yield in Semi-Arid Areas of Ethiopia

Soil organic matter depletion is mainly caused by crop residue removal, and low or no application of organic fertilizers often results in nutrient exhaustion and low crop yields. This challenge requires the evaluation of different organic fertilizer resources to provide new alternative fertilizer products to an Ethiopian production system. Based on this fact, an experiment was conducted to evaluate the effects of mela organic fertilizer as a supplementary fertilizer to improve the yield of tomatoes under irrigation in the Central Rift Valley of Ethiopia from 2020 to 2021. The experiment consisted of eight treatments (Control, 100% recommended fertilizer, 100% recommended fertilizer + 30 L/ha Mela, 100% recommended fertilizer + 45 L/ha Mela, 75% recommended fertilizer +30 L/ha Mela, 75% recommended fertilizer + 45 L/ha Mela, 50% recommended fertilizer +30 L/ha Mela and 50% recommended fertilizer + 45 L/ha Mela) laid out in randomized complete block design with three replications. The results revealed that the highest agronomic yield was obtained by applying the 100% recommended fertilizer + 30 L/ha Mela. However, based on the partial budget analysis, the highest marginal rate of return was obtained from 50% recommended fertilizer + 45 L/ha Mela. Thus, it can be concluded that the application of Mela Organics up to 45 L/ha, integrated with chemical fertilizer applications, can increase tomatoes' economic yields and reduce fertilizer costs.

Development of microsatellite markers and evaluation of the genetic diversity of the edible sea anemone Paracondylactissinensis (Cnidaria, Anthozoa) in China.

Paracondylactissinensis Carlgren, 1934 is a sea anemone with economic value in China. The wild population of P.sinensis has been shrinking due to overfishing and environmental pollution, which have caused price instability. In winter, the price of P.sinensis can reach 25 USD per kilogram. Up to now, there are no genetic markers developed for P.sinensis, preventing a further exploration of their population genetic diversity. In this study, the full-length transcriptome of P.sinensis was sequenced and microsatellite DNA markers (simple sequence repeats [SSRs]) were developed from those transcripts. A total of 52 primer pairs, which can amplify specific polymorphic bands in PCR experiments, were designed for the SSR markers. Genetic diversity and population genetics were analysed for P.sinensis populations collected from the coasts of Taizhou and Rizhao using six microsatellite DNA loci. While inbreeding was detected in both populations (Fis > 0), the overall number of alleles (Na = 11.3) and bottleneck analysis suggested that the genetic diversity of P.sinensis has not been greatly impacted. Clustering analyses using STRUCTURE, principal coordinate analysis and unweighted pair group method with arithmetic mean tree revealed that the Taizhou population diverged from the Rizhao population; however, the genetic differentiation between the populations was moderate. Human-mediated commercial activities may be the principal reasons for the gene flow between the populations. Our study provides the first evaluation of the genetic resources of wild P.sinensis populations in China, which can serve as a useful reference for future comparative studies on population genetics and may guide policy-makers in initiating strategies for germplasm conservation and artificial breeding.

Impact of Overpressure on the Preservation of Liquid Petroleum: Evidence from Fluid Inclusions in the Deep Reservoirs of the Tazhong Area, Tarim Basin, Western China

The complexity of petroleum phases in deep formations plays an important role in the evaluation of hydrocarbon resources. Pressure is considered to have a positive impact on the preservation of liquid oils, yet direct evidence for this phenomenon is lacking in the case of deep reservoirs due to late destruction. Here, we present fluid-inclusion assemblages from a deep reservoir in the Tazhong area of the Tarim Basin, northwestern China, which formed as a direct consequence of fluid pressure evolution. Based on thermodynamic measurements and simulations of the coexisting aqueous and petroleum inclusions in these assemblages, the history of petroleum activities was reconstructed. Our results show that all analyzed fluid-inclusion assemblages demonstrated variable pressure conditions in different charging stages, ranging from hydrostatic to overpressure (a pressure coefficient of up to 1.49). Sequential petroleum charging and partial oil cracking may have been the main contributors to overpressure. By comparing the phases of petroleum and fluid pressures in the two wells, ZS1 and ZS5, it can be inferred that overpressure inhibits oil cracking. Thus, overpressure exerts an important influence on the preservation of liquid hydrocarbon under high temperatures. Furthermore, our results reveal that the exploration potential for liquid petroleum is considerable in the deep reservoirs of the Tarim Basin.

Weight Assignment Method and Application of Key Parameters in Shale Gas Resource Evaluation

The evaluation methods for shale gas resources and the key parameters involved are diverse. The main research object of this article is the key parameters in shale gas resource evaluation, and this study aims to quantitatively evaluate the required key parameters for calculation, thereby improving the credibility of shale gas resource evaluation results. This article mainly analyzes the weight analysis of the key parameters used in the resource evaluation process, focusing on the analysis and determination of key parameters controlling the generation, enrichment, and preservation of shale gas. The key parameters are graded and evaluated layer by layer, and the common key parameters that participate in the determination are extracted. Based on the above analysis, a weight conversion model is proposed to quantitatively evaluate the actual importance of key parameters in resource evaluation. By combining statistical research, the partial correlation coefficients in the correlation coefficients are applied to estimate the resource quantities in the exploration field in order to quantitatively evaluate the credibility of the resource evaluation results. This article focuses on the weight assignment of key parameters for calculating the resource quantity of the Jiaoshiba shale gas field in the Fuling area of Chongqing and obtains different weight results for different parameters. Using this method to assign key parameter weights to the target block can provide reliable parameter support for shale gas resource evaluation and provide strong support for shale gas resource estimation.

Statistical evaluation and quality analysis of water resources around quarry site in Abuja Suburban Nigeria

Water resources occupies vital position regarding the lifespan and general wellbeing humans while significant shortfalls on its reserves hinders almost all sustainable development globally. Most host communities to quarry companies without a water treatment plant are greatly affected by the use of water resources within its area. The present study highlights statistical evaluation and quality analysis of water resources around a quarry site in FCT Nigeria. The research engaged biological assay, physiological and chemical analysis to quantify contamination level of the water resources from obtained data which were also subjected to statistical analysis. The statistical tools employed are Pearson's Correlation, descriptive statistics, Levene's test for homogeneity and one–way analysis. The physiochemical analysis revealed the water resources to have high turbidity value in 58.3 % of sampled population while nitrate concentration and electrical conductivity value were very low. The bioassay revealed presence of coliform bacteria in 100 % of sampled population while thermotolerance count discovered disease-causing-pathogens in 41.7 % of sampled population. Chemical analysis revealed that Pb, Cr, Ni and As were 91.7 %, 83.3 % 100 % and 100 % above recommended permissible limits for sampled population. These results suggests that water resources in this study is unsafe and holds a health-treat with regards to the contaminations inherent in them. Statistical evaluation revealed average positive linear relationship between heavy metal concentration suggesting close relationship of contamination source. Observed strong positive linear relationship between lead and copper, nickel and chromium as well as nickel and arsenic in the scatterplot depicts same source of contamination.

SLOPE: Safety LOg PEripherals implementation and software drivers for a safe RISC-V microcontroller unit

The focus of this manuscript is related to the main safety issues regarding a mixed criticality system running multiple concurrent tasks. Our concerns are related to the guarantee of Freedom of Interference between concurrent partitions, and to the respect of the Worst Case Execution Time for tasks. Moreover, we are interested in the evaluation of resources budgeting and the study of system behavior in case of occurring random hardware failures. In this paper we present a set of Safety LOg PEripherals (SLOPE): Performance Monitoring Unit (PMU), Execution Tracing Unit (ETU), Error Management Unit (EMU), Time Management Unit (TMU) and Data Log Unit (DLU); then, an implementation of SLOPE on a single core RISC-V architecture is proposed. Such peripherals are able to collect software and hardware information about execution, and eventually trigger recovery actions to mitigate a possible dangerous misbehavior. We show results of the hardware implementation and software testing of the units with a dedicated software library. For the PMU we standardized the software layer according to embedded Performance Application Programming Interface (ePAPI), and compared its functionality with a bare-metal use of the library. To test the ETU we compared the hardware simulation results with software ones, to understand if overflow may occur in internal hardware buffers during tracing. In conclusion, designed devices introduce new instruments for system investigation for RISC-V technologies and can generate an execution profile for safety related tasks.

The development and evaluation of a fact sheet resource for women managing menopausal-related cognitive complaints.

Cognitive symptoms are frequently reported by women during the menopause transition years. The aim of this research was to codesign and evaluate a fact sheet resource to help women understand and manage cognitive symptoms that may occur during menopause. This study adopted a codesign approach involving women during the menopause transition years as well as professionals to develop and evaluate a fact sheet, with a focus on acceptability and safety. Four phases (discover, define, develop, deliver) were conducted to develop, refine, and evaluate the fact sheet using a mixed-methods approach of focus groups, interviews, and surveys. The discover phase identified a need for online educational resources for women in premenopause, perimenopause, and postmenopause to learn about menopause-related topics. The define and develop phases, relying on focus group sessions with perimenopausal and postmenopausal women, revealed common themes related to the experience of cognitive symptoms and a desire for management tips to optimize cognitive functioning. Structured interviews with professionals highlighted a desire for more concrete examples of cognitive symptoms. The results of the deliver phase found strong acceptability for the fact sheet, alongside requests for additional information on menopausal hormone therapy from premenopausal, perimenopausal, and postmenopausal women. The study reported a wide range of cognitive symptoms among women during the menopause transition years. This study showed broad agreement on the fact sheet's acceptability and safety in addressing menopausal cognitive symptoms. Feedback on menopausal hormone therapy and management tips underscores the demand for more research on effective interventions.

Designing Digital Resources for Multimodal Composition in the Kindergarten Environment

In the contextual field of environmental composition in kindergarten, transforming it into a space for cognitive, social, emotional, i.e., holistic formation and development of the child, multimodality operates with authenticity, magnetism, multilevelity, multidimensionality, and dynamism to overcome schematicity and linearity of thinking, thus stimulating imagination. Leading the way is the understanding that the environmental composing of multimodality in kindergarten is the foundation of quality for the child’s cognitive, affective, sensory cognition and self-knowledge. This paper outlines the parameters of evaluating multimodal digital resources designed by students preparing for future kindergarten teachers. The starting points for their expertise in the relations of autonomy, coherence, justification, adequacy and authenticity as subjectively significant and objective wholes of multimodal composing are argued. Criteria and indicators for the expert evaluation of digital resources for multimodal environmental composing in kindergarten, as modeling and provoking and enriching the individual sensory experience of the child, as an opportunity to stimulate cognitive and personal activity are derived. It is necessary to conclude that through the design of multimodal digital resources, the existing contradictions in the starting conditions of the pedagogical interaction in the kindergarten will be overcome. The main recommendation points to the need for specific training of future children’s teachers for multimodal environmental composition of educational practices in kindergarten, synergizing different modalities, rather than their linear sequential environmental combination.

Evaluation of Pathology Resources for Cervical Cancer Detection Between 2018 & 2022: a Retrospective Study at Moi Teaching and Referral Hospital, Western Kenya.

Cervical cancer cases are increasing in sub-Saharan Africa, particularly in Kenya, exacerbated by inadequate histopathology resources, posing a significant barrier to timely diagnosis and treatment. There has been little research on the availability and evolution of histopathology resources for diagnosing cervical cancer over the years. This retrospective study evaluated this evolution at Moi Teaching and Referral Hospital in Kenya between 2018 and 2022. We used a mixed-methods approach. An in-depth interview was conducted with one of MTRH's pathology laboratory staff to assess the equipment, personnel, and quality control trends between 2018 and 2022. A thematic analysis was conducted in NVivo. We also retrospectively conducted a comprehensive inventory review of laboratory resources from 2018-2022 via purposive sampling. Microsoft Excel and Stata version 17 were utilized for descriptive statistical analysis. Turnaround time (TAT) was assessed against the UK's National Health Service Cervical Screening Program guidelines. The number of histopathology laboratory personnel at MTRH increased from 2018 to 2022, during which the facility included two pathologists, one records person, and one office administrator. Patient annual visits increased from approximately 350,000 in 2018 to approximately 500,000 in 2022. However, the histopathology personnel-to-population ratio decreased from 1.5 pathologists and 2.7 histo-technicians per 100,000 in 2018 to 1.4 pathologists and 1.8 histo-technicians per 100,000 in 2022. Despite this decrease, lab equipment, automatic tissue processors and embedding machines were added, and an average 14-day turnaround time was maintained for pathology reports. Despite a decreased personnel-to-patient ratio, the addition of crucial histopathology equipment mirrors the operational commitment of the Moi Teaching and Referral Hospital. The 14-day TAT is commendable, contributes to operational effectiveness and significantly contributes to timely detection. The hospital's dedication to upgrading its infrastructure underscores a proactive approach to addressing growing healthcare demands and improving patient outcomes, even with limited human resources. The decline in the personnel-to-patient ratio underscores challenges in diagnosis, emphasizing the need to address workforce and infrastructure gaps to improve patient care within similar low-resource settings.

Analysis of Phenotypic Trait Variation in Germplasm Resources of Lycium ruthenicum Murr.

Exploring the phenotypic trait variation and diversity of Lycium ruthenicum germplasm resources can support selection, breeding, and genetic improvement, enhancing agricultural production. This study collected 213 wild Lycium ruthenicum seedlings from a resource nursery in Alxa League, Inner Mongolia. These seedlings originated from eight sources across four provinces. Using 11 pseudo-qualitative traits and 20 quantitative traits, the phenotypic variation of the germplasm was analyzed. The analysis involved the coefficient of variation, Shannon–Wiener index (H), Simpson’s genetic diversity index (D), principal component analysis, correlation analysis, and Q-type cluster analysis. The results showed that the variation range of 31 phenotypic traits across the 213 Lycium ruthenicum germplasm resources was 17.26% to 105.41%, with an average coefficient of variation of 39.85%. The H and D indexes ranged from 0.18 to 1.58 and 0.20 to 0.75, respectively. For the 11 pseudo-qualitative traits, the H and D ranges were 0.18 to 1.58 and 0.07 to 0.74, with average values of 0.77 and 0.42. For the quantitative traits, the H and D ranges were 0.54 to 1.49 and 0.25 to 0.75, with average values of 1.21 and 0.63. This indicates that Lycium ruthenicum germplasm resources exhibit significant phenotypic diversity, with quantitative traits showing higher diversity than pseudo-qualitative traits. Principal component analysis revealed that the cumulative variance contribution rate of the first 10 principal components was 74.03%, comprehensively reflecting the information of the 31 traits. Q-type cluster analysis grouped the 213 Lycium ruthenicum germplasm resources into six clusters, each with distinct phenotypic characteristics. This analysis also identified the trait characteristics and breeding value of each cluster. The results of this study provide valuable information on the genetic improvement, conservation, and evaluation of Lycium ruthenicum germplasm resources.

Integrated Analysis of Metabolomics, Flavoromics, and Transcriptomics for Evaluating New Varieties of Amomum villosum Lour.

Amomum villosum Lour. (A. villosum) is the original plant of the medicinal and culinary spice Amomi Fructus (Sharen) and is an important economic crop in the Lingnan region of China. During the cultivation and production of A. villosum, prolonged reliance on single asexual reproduction has exacerbated the degradation of its varieties, leading to inconsistent yields and quality. Building upon earlier cultivar selection efforts, this study provides a comprehensive evaluation of two newly bred A. villosum varieties (A11 and A12) from perspectives including plant traits, product characteristics, active ingredients, and multi-omics analysis. It was found that A12 plants display enhanced robustness, more aromatic fruits, higher yields, and elevated levels of bornyl acetate, A11 shows the advantage of a high camphor content, and the different metabolites and differentially expressed genes of the two varieties were significantly enriched in multiple metabolic pathways. Additionally, A12 contained more terpenoids and substances with aromatic odors such as sweet, fruity, floral, and green. Furthermore, a key gene (Wv_032842) regulating the acetylation of bornyl was discovered, and its significantly higher expression, in A12. In conclusion, this study has a guiding significance for the evaluation of germplasm resources and the breeding of excellent varieties of A. villosum.
