(NH4)4[SO4][CB11H12]2: a new double salt with carbaborate anions crystallizing in a monoclinic variant of the anti-K2NiF4-type structure
Authors: Friedly Alexandra , Schleid Thomas
Published: January 2025

The new double salt with the empirical formula (NH4)4[SO4][CB11H12]2 can be obtained by the reaction between an aqueous solution of the free acid of the closo-carbaborate (H3O)[CB11H12] and aqueous ammonia (NH3), when the incorporated sulfate anions are introduced by a cation exchanger due to its regeneration with sulfuric acid (H2SO4). (NH4)4[SO4][CB11H12]2 is yielded as colorless, prismatically shaped crystals with a considerable size up to 1 mm. This ammonium sulfate carbaborate crystallizes in the monoclinic space group C2/c with the lattice parameters a = 2715.32(9), b = 713.91(2), c = 1391.24(5) pm and β = 109.203(2)° with four formula units per unit cell. Due to the formation of bridging hydrogen bonds, the [SO4]2− anions and the (NH4)+ cations form

{([(N1)H4]2/2[(N2)H4]2/2[(N3)H4]2/1[SO4]2+} layers parallel to the bc plane. Between these positively charged layers, the [CB11H12]− anions are placed in fashion of the anti-K2NiF4-type structure, where K+ is replaced with [CB11H12]− and [SO4]2−-centered [(NH4)+]6 octahedra, which share four coplanar corners, arrange to the above-mentioned layers. In the Raman spectra of (NH4)4[SO4][CB11H12]2, the dominating bands correspond to the well-known vibration modes of the closo-carbaborate cage. The bands resulting from the (NH4)+ and [SO4]2− ions are visible, but significantly less intense as compared to the vibrations of [CB11H12]−, which can be explained by the formation of hydrogen bonds.
Russian Foreign Policy towards Cyprus:
Authors: Evaghorou Evaghoras
Published: January 2025

Cyprus is an important area for Russian foreign policy, as developments in the Eastern Mediterranean, where the island is located, affect Moscow’s strategic interests. This article analyzes and interprets the diplomatic, political, economic, energy, and geostrategic aspects of Russian foreign policy towards Cyprus. It identifies the motives behind Russian behavior towards the Republic of Cyprus (RoC) and concludes that, despite generally good diplomatic and friendly relations, the two states have differing geostrategic interests. Given that the defense of Russia’s national interests, in relation to Cyprus and the Eastern Mediterranean, is a priority for Moscow, the article concludes with assessments of future trends, including the developments in the Russian-Ukrainian war and its consequences, which have negatively affected the relations between the two states.

Published: January 2025

This research aims to examine the relationship between ability and effort, intellectual skills, emotional skills, spiritual skills, digital skills and students' entrepreneurial character and abilities. The quantitative method was obtained through an online survey involving 200 students from Private IKIP in Central Java. Data were analyzed using Structural Equation Modeling (SEM), because it is able to test complex relationships between latent variables and indicators simultaneously and provide accurate estimates of the structural and measurement models. The research results show that ability (AE) has a significant relationship of 1.15%, while emotional skills (ES) make a small contribution of 0.13% to entrepreneurial character (later_var1). Intellectual skills (CG) have a strong influence of 0.04%, Digital Skills (DS) have a strong influence of 0.21%, and spiritual skills (SS) have a strong influence of 0.91% on entrepreneurial ability (laten_var2). However, no significant direct relationship was found (0%) between entrepreneurial character (laten_var1) and entrepreneurial ability (laten_var2). These findings show that ability and effort, intellectual skills, emotional skills, spiritual skills, digital skills can shape character and entrepreneurial abilities. This study identifies limitations of the model and sample, and recommends moderating factors in future research.
Žudiko tapatybės paradoksai
Authors: Sireikis Augustas
Published: January 2025

The article examines a short story “My Friend Sigitas” [Mano draugas Sigitas] by Alvydas Šlepikas through the lens of Jacques Lacan’s structural psychoanalysis. The main focus is placed on identification, which, unlike in the classical tradition of psychoanalytic literary criticism, is examined not as a mental act of the author or reader, but as an action of verbal communication, embedded in the literary text itself. Thus, a seemingly simple and funny story about the death of a friend is revealed to be rendered around a paradox: through various discursive operations, the homodiegetic narrator simultaneously tries to accept and reject the accusation of murder. In this way, contrary to a common assumption, a traumatic structure of discourse is associated not with a victim or witness, but the accused, i.e., the position of a potential murderer. The latter is analysed neither from the legal perspective, which due to the narrator’s justification to the addressee would be natural in empirical reality, nor by speculating about the inner experiences of the subject, as if he were a real person. By comparing this research strategy with possible alternatives, we demonstrate the differences between psychological and psychoanalytical interpretation of literature.

Authors: RABELO HENRIQUE MARCELO , BRAZ SILVA SANDRO , SAPORITO ANTONIO
Published: January 2025

Objective: The present research consists of analyzing the behavior of the determinants of the capital structure of Argentine and Chilean companies between 2007 and 2016.Method: To achieve the purpose of this study, the following methodological characteristics were used: a) quantitative approach; b) research typologies were used: bibliographic, documentary, exploratory and explanatory; c) ten-year period (2007 to 2016) of Argentine and Chilean companies considering the financial reports extracted from the Economática database software; d) four statistical tools: 1) analysis; 2) Pearson correlation; 3) variance inflation factor (VIF); 4) panel data regression and tool-related tests.
Main results: The results show that Chilean companies have higher long-term and costly long-term indebtedness; Argentine companies with total, short-term and onerous short-term debt. Argentine companies have high averages in tangibility, return on assets, income tax, tax savings and profit volatility; Chilean companies have high averages in current liquidity, return to shareholders, growth in sales and assets, and market-to-book. Relevance/originality: The study focuses on two South American countries, Argentina and Chile, where there is a gap in the literature regarding studies related to these two markets when it comes to capital structure determinants. Theoretical/methodological contributions: The findings also lead us that Argentine and Chilean companies are more prone to the pecking order theory. Other indebtedness variables and their determinants are suggested in future research, in addition to the speed of indebtedness adjustment.
GESTÃO DE RISCOS
Authors: LORENZI JUNIOR DAVID , Haubert Pilger Alex
Published: January 2025

Este estudo teve como objetivo a avalição dos riscos existentes em contratos de mão de obra terceirizada, e a partir deste propor uma ferramenta de gestão de riscos voltada para a minimização dos riscos existentes no processo de contratação de mão de obra terceirizada na Instituição de Ensino Federal. Com a crescente necessidade de cumprir com legislações vigentes e o considerável número de colaboradores terceirizados na instituição, a gestão de contratos administrativos enfrenta desafios relacionados à exposição a diversos riscos, cuja não administração pode acarretar prejuízos à administração pública. Nesse contexto, a pesquisa buscou investigar a viabilidade de uma ferramenta de gestão de riscos que possa servir como modelo ou proposta metodológica nos processos de contratação de mão de obra terceirizada pela IES, auxiliando nas tomadas de decisões em ambientes de contratos com incertezas. A metodologia adotada é de natureza exploratória e qualitativa, configurando-se como um estudo de multicasos baseado em quatro contratos de serviços terceirizados na IES. Foram entrevistados quatro gestores de contratos ou fiscais setoriais e a análise dos dados foi realizada por meio da técnica de análise de conteúdo, permitindo uma compreensão mais aprofundada das respostas dos entrevistados e a identificação de padrões e temas relevantes. Os resultados revelaram a ausência de aplicação da política formal de gestão de riscos, lacunas de conhecimento sobre o tema por parte de alguns entrevistados e a falta de mapeamento de riscos nos contratos. A presente pesquisa contribuiu para uma compreensão mais aprofundada dos desafios enfrentados na gestão de contratos de mão de obra terceirizada na Instituição de Ensino Federal e sugere a necessidade de implementação de medidas de gestão de riscos para mitigar potenciais impactos adversos. Entretanto, considera-se como limitação, o fato de ter sido realizado em uma única instituição. Isso limita a generalização dos resultados para outras universidades ou instituições de diferentes portes, setores ou contextos.

Published: January 2025

Este estudo busca compreender a relação entre o conflito organizacional e a ausência de competências comportamentais, conhecidas como soft skills, entre montadores e soldadores das indústrias de metalurgia e mecânica da Serra Catarinense. A pesquisa apresenta evidências empíricas que demonstram como a carência de soft skills afeta negativamente a dinâmica profissional e a produtividade, contribuindo para o debate sobre a relevância dessas competências no ambiente de trabalho. Utilizando uma abordagem fenomenológica, foram realizadas entrevistas semiestruturadas com montadores e soldadores. Os dados foram analisados por meio da análise de discurso, com foco na intersubjetividade, nas percepções dos sujeitos sobre as relações interpessoais e no ambiente ao seu redor. Os resultados indicam que a ausência de proatividade, resistência à mudança, imediatismo e problemas de comunicação criam barreiras significativas para a produtividade e a harmonia organizacional. Os achados revelam as causas dos conflitos e sugerem que, sem intervenções específicas, a ausência dessas competências continuará a impactar a dinâmica organizacional e a eficiência produtiva.
Single-molecule biochemical characterization of human β-cardiac myosin purified from non-virally transfected C2C12 cells
Authors:   , Velayuthan Lok Priya
Published: January 2025

Myosin II is a molecular motor that primarily functions in muscle contraction where it generates force and motion through cyclic interaction with actin filaments, driven by ATP turnover. Gaining mechanistic insights into actomyosin energy transduction is essential, particularly in the context of mutations associated with hypertrophic cardiomyopathy (HCM), a genetic condition linked to altered cardiac function. The current approach for studying mutations in the myosin motor domain relies on protein expression in C2C12 cells using an adenovirus-based transfection system. However, this method is constrained by slow turnaround time and labor-intensive protocols. This thesis presents a virus-free transfection method to express human β-cardiac myosin subfragment-1 (denoted as S1L) in C2C12 cells using commercially available chemical reagents – JetPrime and GenJet. The purified S1L proteins exhibited actin-activated ATPase and sliding velocities (using in vitro motility assay) were comparable to those obtained using the virus-based system. Our new alternative method provides a faster and less complex approach for screening a wide range of HCM mutations. Furthermore, a highly miniaturized single-molecule ATPase assay was developed to leverage the advantage of the virus-free expression system. Using total internal reflection fluorescence microscopy (TIRF), fluorescent ATP turnover rate constants for myosin were determined for both basal and actin-activated conditions. The latter was obtained by crosslinking S1L proteins to surface-immobilized actin filaments via EDC (1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride) crosslinker. The observed turnover rates were consistent with those obtained from solution-based kinetic assays. By integrating the virus-free expression system with the single-molecule ATPase assay, several S1L point mutations, including R243E, R243E+E466R, R243C, and R243H were biochemically characterized alongside the classical HCM mutations R403Q and R453C. The R243 mutants are of particular interest, as this residue plays an important role in the secondary Pi binding site and may influence the multistep process of inorganic phosphate release. Initial findings suggest that the R243C mutation could serve as a promising model for investigating orthophosphate release, potentially offering deeper insights into the molecular mechanisms underlying HCM pathogenesis.
Optimising school management strategies: Empowering school management teams through revision of the learners’ code of conduct for effective discipline management
Authors: Lumadi Rudzani Israel
Published: January 2025

In the study reported on I investigated how empowering school management teams through a revised learners’ code of conduct can improve school discipline management. Using a quantitative research methodology with an exploratory design, data were gathered from 127 respondents across 50 selected schools in the Vhembe district of the Limpopo province, South Africa. School management teams and teachers completed surveys focused on managing learner discipline. Data were collected through a closed-ended Likert scale questionnaire. The collected data were analysed using an IBM SPSS 26 statistical program. Grounded in social learning theory, I aimed at repositioning a learners’ code of conduct to enhance discipline management. The effectiveness and enforceability of a code by the school management teams while assessing their legal compliance competencies were specifically analysed. The findings reveal that school management teams often lack effective strategies and interventions to tackle learner discipline challenges. I emphasise that it is crucial for South African researchers to continue making meaningful contributions to the teaching profession, despite its current instabilities. This study contributes to the body of knowledge on school management strategies and provides valuable insights for optimising discipline management practices in schools.
Evaluación del calostro y su relación con los niveles séricos de inmunoglobulinas y crecimiento de las crías, en dos hatos de vacas doble propósito en el sureste de México
Authors: Santos Ricalde Ronald
Published: January 2025

Se evaluó la calidad del calostro en vacas y se relacionó con el nivel de inmunoglobulinas séricas y la ganancia de peso de sus terneros. Se utilizaron 30 vacas de dos fincas (20 de FMVZ y 10 de Kampepen) con sus respectivos terneros. El calostro se obtuvo dentro de las primeras 24 horas posparto. No se encontró diferencia significativa en la concentración de inmunoglobulinas séricas entre los terneros de ambas granjas, ni en sus ganancias de peso (p > 0.05). En ambos lugares, los terneros presentaron concentraciones de inmunoglobulinas superiores al mínimo recomendado para una adecuada protección (20 UTSZ o mg/mL). La correlación entre el nivel de inmunoglobulinas del calostro y las inmunoglobulinas séricas del ternero fue baja (0.27), lo que significa que la inmunidad pasiva del ternero no sólo depende de la calidad del calostro, sino también de la cantidad de calostro ingerido y el momento de la ingesta.
Soluble immune checkpoint molecules: mechanism of formation, function, role in malignant neoplasms
Authors: Glazanova T. V. , Pavlova I. E. , Kuzmich E. V. , Bubnova L. N.
Published: January 2025

Immune checkpoints (ICs) represent a broad set of stimulatory and inhibitory signaling pathways playing an important role in regulation of immune responses. Initially, ICs have been considered solely as cell membrane-bound receptor and ligand systems, triggering or blocking immune cell function. Over the past decade they have been proven to exist in soluble forms (sICs). sICs are biologically active regulators involved in paracrine and systemic modulation of immune responses, similar to cytokines. Normally, sICs exert both stimulatory and inhibitory effects on the immune system, and their balance may be disturbed in many malignant neoplasms, COVID-19, HIV infection. There is a lot of data on the connection between sICs and various diseases, but a number of key aspects of their biology have not been fully clarified. The most widely studied are PD-1 (programmed death receptor-1) and its ligands PD-L1 and PD-L2, CTLA-4 (cytotoxic T lymphocyte antigen-4), TIM-3 (T cell immunoglobulin and mucin-domain containing-3), VISTA (V-domain Ig-containing suppressor of T cell activation). The mechanisms of soluble form formation are complex and diverse and include alternative splicing, cleavage of membrane ectodomains, and proteolytic cleavage. The most important molecular mechanisms underlying the synthesis and release of sPD-1 and sPD-L1 are alternative splicing of mRNA and translation of isoforms lacking transmembrane domains, while the formation of sTIM-3 occurs by cleaving the extracellular regions of transmembrane proteins by protease ADAM10. The review article provides data on the main sICs, including sPD-1, sPD-L1, exosomal sPD-L1, sCTLA-4, and several others. The molecular mechanisms of their formation, biological functions in maintaining immune homeostasis, prognostic significance of changes in their content are described in patients with solid malignant tumors (nonsmall cell lung cancer, hepatocellular cancer, breast cancer, kidney cancer, skin cancer, gastric cancer, etc.), as well as for hematologic malignancies (lymphoma, chronic lymphocytic leukemia, acute myeloblastic leukemia, multiple myeloma).

Nos últimos 40 anos os desastres naturais provocaram mais de 3,3 milhões de óbitos no mundo, e a cada ano, cerca de 226 milhões de pessoas são afetadas pelos mesmos, sendo 102 milhões por eventos hidrológicos. Este número indica a necessidade de ações para minimizar as consequências deles na sociedade e um aspecto importante a considerar é a liderança. Situações de desastres exigem presença e respostas de líderes diversificadas e muitas vezes incluem a necessidade da flexibilidade e adaptabilidade para tomar decisões rapidamente e reunir recursos num curto espaço de tempo. O objetivo deste estudo é apresentar estudos sobre liderança em contexto de desastres para contribuir no aprendizado de como liderar situações desta natureza. Foi realizada uma revisão integrativa de estudos publicados na base de dados da SCOPUS e Web of Science, encontrados com os descritores “disaster and leadership”, de 2020 a 2024. A busca resultou em 198 artigos. Após leitura dos resumos, foi possível selecionar 41 artigos que atendiam ao objetivo deste estudo. Foi possível verificar que os estudos enfatizam a necessidade de treinamento para enfrentamento de desastres bem como a importância da liderança nas intervenções relacionadas aos desastres.

Development of a Public Road Works Contract Management Framework for the Zambian construction industry
Authors: Munga L , Mwiya B
Published: January 2025

Road contracts are not always delivered within time, on budget and to the required quality. Consequently, the aim of this study was to develop a Public Road Contract Management Framework for the Zambian Construction Industry (ZCI) to facilitate timely completion of roadworks, which are executed to the desired quality, and at the budgeted cost. The study adopted a sequential exploratory research design to identify and determine the associated challenges and critical success factors (CSFs), respectively, in the ZCI. This was achieved by initially conducting an extensive literature review. Ranking the data obtained from 92 respondents via a survey questionnaire revealed the following as some of the major challenges: viability of strategic plans being affected by political regime changes, failure to allocate the contract with the required funds, lengthy payment processes, and lack of reviews to document lessons learnt and best practices. Some of the top CSFs were the following: preparation of comprehensive feasibility studies, allocating the contract with the required funds in the budget, adequate funding during implementation, and enhanced record keeping. The developed framework was validated by seven experts through a Delphi technique. The Spearman correlation coefficient showed that there was a strong positive relationship of 0.776 between contract implementation and monitoring and control.

Published: January 2025

Detailed analyses of uranium-bearing phosphate nodules from 11 localities in eastern Kansas are reported. Seven Pennsylvanian shales were sampled. Graphs showing relationships between phosphate content and several constituents, including uranium, are presented. Combined evidence suggests that the nodules consist of collophane and dahllite with varying mixtures of impurities, primarily quartz and clay. The average composition of the 11 samples was 30.2 percent P2O5 0.017 percent U3O8 and 3.2 percent fluorine.
Application of the Tri-Axial Type Diagram to the Study of Concrete Masonry Batch Mixes in Plant Practice
Authors: Hardy Ronald G.
Published: January 2025

A study of the effects and results of using various combinations of a lightweight aggregate, Portland cement, and water on the properties of 8 by 8 by 16 inch masonry units was undertaken. For this work two series of tests were performed; on one series a Stearns No. 9 Joltcrete block machine was utilized and on the other a Besser Vibrapac. The aggregate gradation used was checked at each batch to note any variations. The tri-axial method of plotting and organizing the batch compositions and data was employed for the study and proved to be an excellent means for correlating variations. Data indicate that there is an optimum water content which must be maintained for best overall results. At this water content the cement-aggregate proportions can be varied widely yet produce very satisfactory blocks. It was also noted that variations in water content affected block texture markedly. While the data presented could apply only to the particular aggregate studied, this method is suggested as an easy means for any block manufacturer to study mixes to work toward optimum conditions.
Additional Studies of the Cenozoic of Western Kansas
Authors: Merriam Daniel F. , Frye John C.
Published: January 2025

Subsurface data, obtained largely from ground-water test drilling, are utilized for the preparation of generalized areal geology and topography on the bedrock surface below the Cenozoic deposits of western Kansas. The geologic pattern is consistent with the regional pattern of areal geology shown on the State map of Kansas. The sub-Cenozoic topography reveals a recognizable pattern of bedrock valleys, developed in part during late Tertiary time and in part during Pleistocene time. Structure contours drawn on the "Algal limestone" at the top of the Ogallala formation are compared with structure contours drawn on the top of the Dakota formation. The Tertiary structural development of western Kansas is indicated by a map showing convergence between the Dakota and Ogallala formations.
Thickness Maps as Criteria of Regional Structural Movement
Authors: Lee Wallace
Published: January 2025

A map depicting the thickness of a sequence of rocks between surfaces that were once flat or relatively flat records the structural movements that occurred between the development of the limiting surfaces. Such an isopachous map is essentially a structure map of the first surface at the time of the second. The accuracy with which such maps reveal the structural movements that took place during the interval depends on how closely the limiting surfaces approached a plane. The deformation is most accurately revealed where the confining surfaces were depositional. Erosional surfaces of low topographic relief may be used to reveal regional warping of broad areas. The relation of the sequence of rocks to underlying and overlying formations determines the time of movement. Isopachous maps that include sequences of formations whose thicknesses were separately controlled by conflicting patterns of folding express a composite of both movements and reveal neither.

Four commercial-type clays from the Dakota formation were studied by chemical and spectrochemical analysis, x-ray diffraction, electron and light microscopy, differential thermal analysis, mechanical analysis, and specific surface measurements. The basic chemical and physical properties so determined are compared with pH, apparent viscosity, and the results of empirical ceramic tests, including water of plasticity, shrinkage water, pore water, volume and linear shrinkage, fired color, pyrometric cone equivalent, saturation coefficient, apparent porosity, apparent and bulk specific gravity, and hardness at various fired temperatures.
Relationships between green properties and percentage water of plasticity and between green properties and specific surface are shown. The fired properties are shown to be more directly related to chemical and mineralogical composition. There is a correlation between percentage volume shrinkage on firing and percentage of fluxes contained in the clays. The basic properties explain the behavior of the clay materials when subjected to ceramic tests; and, conversely, easily obtained ceramic data can be used for rough determination of basic properties.
Coal Resources of the Marmaton Group in Eastern Kansas
Authors: Schoewe Walter
Published: January 2025

The Marmaton coal-bearing rocks lie directly above the "Cherokee" or main coal-bearing strata in southeastern Kansas and constitute the upper part of the middle Pennsylvanian rocks in Kansas. The coal-bearing rocks crop out in a belt 10 to 25 miles wide extending in a general northeast-southwest direction from Linn and Bourbon counties on the north to Montgomery and Labette counties on the south. Of the 8 to 10 coal seams in the group, only the Mulberry seam in the Bandera shale formation approximately in the middle of the group is being mined. A second coal seam, the Summit, in the Fort Scott limestone formation at the base of the Marmaton group is reported to have been mined although field evidence reveals no trace of mines nor outcrop of minable coal.
The Mulberry coal has been mined in Linn and Bourbon counties, but currently is mined commercially only in Linn County, which ranks third among the coal-producing counties of the State. The coal ranges in thickness from 1 to 4 feet where mined and is thickest in the northern and western parts of the coal-bearing area. The coal lies close to the surface and at depths reaching 120 feet. Currently, virtually all the coal is mined by stripping. The Mulberry is a bituminous coal of high volatile A to B rank. Proximate analyses show B.T.U. value on a moisture- and ash-free basis ranging from 14,200 to more than 15,000, which compares favorably with other Kansas commercial coals. The Mulberry coal can be used for all general purposes. It is estimated that 9,407,000 tons of Mulberry coal has been mined in Linn and Bourbon counties since 1872. Measured coal reserves are calculated at 221,230,000 tons, indicated reserves at 651,264,000 tons, and inferred reserves at 924,000,000 tons, a combined total of 1,796,490,000 tons of all reserve coal. Of the 221,230,000 tons of original measured reserves, 112,547,000 tons is considered recoverable by stripping and 16,649,000 tons minable by underground mining methods. The inferred coal reserves, which are estimated to underlie 703 square miles, extend into Miami, Allen, and Neosho counties.
This report describes the geographic distribution, stratigraphic position, thickness, contact rock, and physical and chemical characters of the Mulberry coal and includes information on the history of Marmaton coal mining, mining methods, production, and coal reserve data. The report consists of two parts. The first part deals with the Mulberry coal in general, whereas the second discusses in detail the occurrence, mining, mining districts, production, and reserves in Linn and Bourbon counties.
Geology and Ground-Water Resources of Jewell County, Kansas
Authors: Fishel V.C. , Leonard A.R.
Published: January 2025

This report describes the geography, geology, and ground-water resources of Jewell County in north-central Kansas. The county has an area of 915 square miles and in 1950 had a population of 9,698. Jewell County lies in the Great Plains Pliocene to Cretaceous ground-water province. The county has three types of topography--the deeply dissected uplands in the northern and central parts of the county, a level or gently sloping plain which bounds the uplands on the east and south, and alluvial valleys.
The rocks that crop out at the surface in Jewell County are sedimentary, ranging in age from Late Cretaceous to Recent. The oldest rocks exposed in the county are sandstone and shale beds of the Dakota formation, which crops out in a small area on the south side of Buffalo Creek valley in the southeastern corner of the county. The Dakota is overlain by a conformable series of marine upper Cretaceous rocks classified, in ascending order: Graneros shale, Greenhorn limestone, Carlile shale, and Niobrara formation. Unconsolidated continental deposits of fluviatile and eolian origin represent at least three stages of the Pleistocene. These deposits include the Meade formation of Kansan age, in the northeastern part of the county between Republican River and White Rock Creek. Stream-laid deposits of the Meade formation also fill a narrow valley extending northward from near Mankato. Volcanic ash deposits and associated silt beds in the northwestern and southern parts of the county also are a part of the Meade formation. Later Pleistocene deposits that are present in Jewell County include terrace deposits of Illinoian and Wisconsinan age, the Loveland and Peoria silt members of the Sanborn formation, and Recent alluvium.
Ground-water recharge in the area is largely from local precipitation; ground-water discharge is mainly by seepage into streams and transpiration by plants. All municipal supplies and most domestic and stock supplies are obtained from wells. Most wells in the county are drilled or dug. No irrigation is practiced in Jewell County. On the whole, ground-water supplies are small.
Ground water in Jewell County is generally hard but otherwise suitable for most uses, except for water from certain wells which is excessively high in dissolved solids content or in nitrate.
The field data upon which this report is based are given in tables. They include records of 259 wells, chemical analyses of water from 36 representative wells, and logs of 13 test holes.
Simpson Filled Sinkholes in Eastern Kansas
Authors: Merriam Daniel F. , Atkinson William R.
Published: January 2025

Six sinkholes involving rocks of Simpson age (Ordovician) were found from examination of logs of wells drilled in eastern Kansas. These sinks contain abnormally thick Simpson sediments, chiefly St. Peter sandstone, which is interpreted as having been deposited as fill in sinkholes developed on an eroded surface of dolomite and limestone of the Arbuckle group. Chert conglomerate and green shale are present in the bottom of the sinks. The shale consists mainly of an illitic clay and quartz, which may be residual weathering products formed in place or washed into the sinks. It is believed that these subsurface features are similar to the Otterville structure in Cooper County, Missouri.
Environment of Deposition of the Grenola Limestone (Lower Permian) in Southern Kansas
Authors: Lane Gary N.
Published: January 2025

Study of the Grenola Limestone (Lower Permian) in the type area, Elk and Cowley Counties, Kansas, indicates that the formation was laid down under generally transgressive conditions, resulting in full development of a lower molluscan phase and an upper molluscoid-fusulinid phase. The Legion and Salem Point Shales represent pauses or slight shallowing in the generally transgressive hemicycle. During the time these members were being laid down, clay-size clastic material was the dominant sediment. Limestones in the formation resulted from deposition of fine-grained to granular calcium carbonate mud.
Except for phases "3" and "5," Elias' Permian cyclothem is well developed in the Grenola formation. The molluscan phase is inferred to be represented by pectinoid limestone, "osagite," and ostracode-bearing shales, which contain intercalated molluscan limestones. Shales containing charophytes may be equivalent to the Lingula phase.
The molluscan phase is characterized by a Cavellina-Hollinella- Tetrataxis microassemblage. The molluscoid-fusulinid phase is characterized by a Climacammina-Glypltostomella-Bairdia microassemblage. Thickness of chert- and fusulinid-bearing limestones in the Neva member increases southward in the area studied. It is postulated that "osagite" beds in the Sallyards and Burr Limestones are the result of wave or current sorting. Osagia is found to be an intergrowth of ?algae and Ammovertella, an arenaceous, incrusting foraminifer.
Flowage in Rock Salt at Lyons, Kansas
Authors: Dellwig Louis F.
Published: January 2025

In the salt mine of the American Salt Company at Lyons, Kansas, flow of salt in pillars is expressed by buckling and fracturing in the floor. Deformation in the salt floor is facilitated by a lubricating shale layer beneath, which permits sliding of the base of the spreading pillars toward rooms and crosscuts, thus exerting a lateral force on the thin salt layer in the floor.
Stratigraphy of Pre-Marmaton Desmoinesian (Cherokee) Rocks in Southeastern "Kansas
Authors: Howe Wallace B.
Published: January 2025

This report presents a detailed stratigraphic study of the pre-Marmaton Desmoinesian (Cherokee) beds exposed in southeastern Kansas. The classification applied is that adopted by northern Midcontinent state geological surveys in 1953. Lithologic successions extending from the top of a given coal bed to the top of the next higher coal bed are classed as formations, the formational name given being that of the most prominent unit included. Certain portions of the Cherokee section are not amenable to such division and have received different treatment. The widespread black shale above the Mulky coal and below the basal Marmaton Blackjack Creek limestone has been termed Excello, and by itself constitutes the Excello formation. Altogether, 17 formations, aggregating 450 to 500 feet in thickness, are recognized in the pre-Marmaton Desmoinesian succession in the area. The Krebs subgroup comprises 6 of these formations, and 11 are included in the overlying Cabaniss subgroup. Establishment of the Krebs and Cabaniss subgroups, which together form the Cherokee group, follows recognition of a time-stratigraphic boundary within the succession. The Venteran Substage (including the Krebs subgroup) and the Cygnian Substage (including the Cabaniss subgroup and Marmaton group) are recognized time-stratigraphic subdivisions of the Desmoinesian Series, (Middle) Pennsylvanian System.
Rocks of five persistent lithologic types compose the typical formation within the Cherokee in southeastern Kansas. These are, in upward order: dark shale and dark, irregular limestone; gray shale; under limestone and sandstone; underclay; and coal. Minor variations of these principal lithologies are useful in identification of individual formations. Especially important are persistent facies of the lower dark shale and irregular limestone division. Under limestones occur principally in formations classed within the Cabaniss subgroup; they grade laterally from thin, impure, irregular to nodular-bedded limestone to evenly bedded. Typically, marine limestone. The horizon in each formation at which under limestone occurs seems to be the position at which additional, possibly nonpersistent cycles of sedimentation may be found in adjacent areas.
