“We’re More than Cows and Plows”: Preservice Agriculture Teachers Use Young Adult Literature to Construct Professional Identities

ABSTRACT The purpose of this collective case study was to explore the impact of using young adult literature in a content area literacy course to leverage the development of professional identities in preservice agriculture teachers (n= 4). Empirical studies of the literacy-based experiences and professional development of agricultural education majors are often absent in teacher education scholarship despite a growing need for agricultural expertise in schools. Interdisciplinary groupings, disciplinary textual study, and teaching demonstrations comprised participant activities in which participants catalyzed their pedagogies through literature. The study followed the qualitative principles of case study methodology and employed interviews, field notes, and artifactual analysis over the course of eight weeks. Results show participants cultivated professional identities by constructing literacy-based learning communities, practicing agricultural instructional design, establishing themselves as experts across multiple fields, and exhibiting feelings of isolation and skepticism in their ability to transfer literary-infused agricultural education from the preservice setting to practice in schools. Implications, interpretations, and recommendations for research are also discussed.
The Hera orebody: A complex distal (Au–Zn–Pb–Ag–Cu) skarn in the Cobar Basin of central New South Wales, Australia

The Hera Au–Pb–Zn–Ag deposit in the southeastern Cobar Basin of central New South Wales preserves calc‐silicate veins and remnant sandstone/carbonate‐hosted skarn within a reduced anchizonal Siluro‐Devonian turbidite sequence. The skarn orebody distribution is controlled by a long‐lived, basin margin fault system, that has intersected a sedimentary horizon dominated by siliciclastic turbidite, with lesser gritstone and thick sandstone intervals, and rare carbonate‐bearing stratigraphy. Foliation (S1) envelopes the orebody and is crosscut by a series of late‐stage east–west and north–south trending faults. Skarn at Hera displays mineralogical zonation along strike, from southern spessartine–grossular–biotite–actinolite‐rich associations, to central diopside‐rich–zoisite–actinolite/tremolite–grossular‐bearing associations, through to the northern most tremolite–anorthite‐rich (garnet‐absent) association in remnant carbonate‐bearing lithologies and sandstone horizons; the northern lodes also display zonation down dip to garnet present associations. High‐T, prograde skarn assemblages rich in pyroxene and garnet are pervasively replaced by actinolite/tremolite–biotite‐rich retrograde skarn which coincides with the main pulse of sulfide mineralization. The dominant sulfides are high‐Fe–Mn sphalerite–galena–non‐magnetic high‐Fe pyrrhotite–chalcopyrite; pyrite, arsenopyrite; scheelite (low Mo) is locally abundant. The distribution of metals in part mimics the changing gangue mineralogy, with Au concentrated in the southern and lower northern lode systems and broadly inverse concentrations for Ag–Pb–Zn. Stable isotope data (O–H–S) from skarn amphiboles and associated sulfides are consistent with magmatic (or metamorphic) water and sulfur input during the retrograde skarn phase, while hydrosilicates and sulfides from the wall rocks display comparatively elevated δD and mixed δ34S consistent with progressive mixing or dilution of original magmatic (or metamorphic) waters within the Hera deposit by unexchanged waters typical of low latitude (tropical) meteoritic waters. High precision titanite (U–Pb) and biotite (Ar–Ar) geochronology reveals a manifold orebody commencing with high‐T skarn and retrograde Pb–Zn‐rich skarn formation at ≥403 Ma, Au–low‐Fe sphalerite mineralization at 403.4 ± 1.1 Ma, foliation development remobilization or new mineralization at 390 ± 0.2 Ma followed by thrusting, orebody dismemberment at 384.8 ± 1.1 Ma and remobilization or new mineralization at 381.0 ± 2.2 Ma. The polymetallic nature of the Hera orebody is a result of multiple mineralization events during extension and compression and involving both magmatic and likely formational metal sources.
Big data analytics capabilities: a novel integrated fitness framework based on a tool-based content analysis

ABSTRACT Big data analytics capability (BDAC) is a firm's ability to leverage big data for business value generation. Firms focus either on ‘functional fitness’ by ‘doing the things right’, or ‘evolutionary fitness’ by ‘doing the right things. Extant literature shows inconsistency in BDAC dimensions and lacks an integrative framework that addresses both functional and evolutionary fitness. We address this through a tool-based qualitative analysis of BDAC literature and present a capability-centric fitness framework. In doing so, we examine the critical role of enterprise architecture and suggest TOGAF based mechanisms to address alignment issues between BDAC’s functional and evolutionary fitness dimensions.
Zinc metabolism in humans: a kinetic model

A quantitative model is developed that describes the kinetics of the early phases of zinc metabolism in humans. The model is based on averaged data obtained over 5 days from 17 atients with smell and/or taste dysfunction who were given 69mZn in trace amounts orally and intravenously. A function describing the rate of entry of 69mZn into systemic plasma following ingestion of the isotope is derived showing that about 37% of the ingested zinc enters plasma. Gastrointestinal absorption is essentially completed by 4 h. Sixty-seven percent of the absorbed zinc in the portal circulation is extracted by the liver before being released into the systemic circulation and agrees with the calculated extraction efficiency from the systemic circulation. There are both rapid and slow exchnage phases between plasma and liver and between plasma and red cells. The calculated steady-state zinc values for plasma, red cells, and liver agree with previously reported measured values implying there are no additional zinc pools in these tissues. The tracer data, however, account for only 10% of total body zinc, the remaining 90% in tissues whose kinetics are too slow to be resolved from a 5-day study.
Volumetrics of Hydrogen Storage by Physical Adsorption

Physical adsorption remains a promising method for achieving fast, reversible hydrogen storage at both ambient and cryogenic conditions. Research in this area has recently shifted to focus primarily on the volumetric (H2 stored/delivered per volume) gains achieved within an adsorptive storage system over that of pure H2 compression; however, the methodology for estimating a volumetric stored or delivered amount requires several assumptions related to the ultimate packing of the adsorbent material into an actual storage system volume. In this work, we critically review the different assumptions commonly employed, and thereby categorize and compare the volumetric storage and delivery across numerous different porous materials including benchmark metal-organic frameworks, porous carbons, and zeolites. In several cases, there is a significant gain in both storage and delivery by the addition of an adsorbent to the high-pressure H2 storage system over that of pure compression, even at room temperature. Lightweight, low-density materials remain the optimal adsorbents at low temperature, while higher density, open metal-containing frameworks are necessary for high-density room temperature storage and delivery.
Do Converged to IFRS National Standards and Corporate Governance Attributes Affect Accounting Conservatism? Evidence from China

The purpose of this paper is to examine the effect of the adoption of converged to IFRS national standards on accounting conservatism (AC) and to investigate the effect of corporate governance (CG) attributes (government ownership, management ownership, concentration of ownership, board size, board independence, CEO duality) on АС in China. The large sample of A-share Chinese listed companies, comprising 26,004 firm-year observations form 2925 companies spanning from 2003 to 2019 collected from CSMAR database and analysed using multivariate regression techniques. The study provides empirical evidence testifying to the decrease in AC level after converged to IFRS national standards in China became mandatory. The findings indicate that government ownership, management ownership, concentration of ownership and CEO duality are all negatively associated with AC. By contrast, board size, board independence, has no significant relationship with AC in Chinese institutional settings. Whereas prior studies investigate the IFRS adoption per se, our study examines how national standards converged to IFRS affect AC indicating that converged national standards produce the analogous effect expected from adoption of the genuine IFRS. Moreover, it means that accounting conservatism is inherent also in the standards as opposed to the conceptual framework. Next, our study is also instrumental in identifying the relationship between AC and CG attributes in an underexplored jurisdiction with a significant impact on the world economy - China. These findings can be utilized and be heeded to by managers in the design of companies’ supreme governing body, as well as regulators while proposing legislation/regulations concerning the composition of the board of directors. The results subject to the limitation for a limited range of CG variables and measurement of accounting conservatism applied. Next, the endogeneity problem is not solved as yet, therefore which direction the causality runs from CG to AC or from AC to CG is disputable.
Molecular Docking Analysis of the Phytochemicals from Tinospora Cordifolia as Potential Inhibitor Against Multi Targeted SARS-CoV-2 & Cytokine Storm

Severe acute respiratory syndrome coronavirus (SARS-CoV)-2, a novel coronavirus, is a member of the Coronoviridae family that has spread worldwide. Developing efficacious therapeutics for the treatment of SARS-CoV-2 is of high priority. Therefore, in this study, the chemical constituents obtained from Tinospora cordifolia are investigated for their in-silico interaction with protein targets crucial for SARSCoV-2 infection and cytokine storm. The five important targets chosen for SARSCoV-2 were the main protease (Mpro), Spike receptor binding domain (Spike-RBD), RNA-dependent RNA polymerase (RdRp or Nsp12), nonstructural protein 15 (Nsp15) of SARS-CoV-2 and the host angiotensin converting enzyme-2 (ACE-2) spike-RBD binding domain and cytokine receptors TNF-[Formula: see text] (Tumor Necrosis Factor-[Formula: see text]) and IL-6 (Interleukine-6). This was accomplished using Maestro 12.4 (Schrodinger Suite) to obtain docking scores. Also, the absorption, distribution, metabolism, elimination, and toxicity parameters (ADMET) were determined using Maestro QikProp modules. The results of computational study revealed that four constituents Cordifolioside-A, Palmatoside-E, Tinocordioside and Tinosporaside significantly antagonize the five targets of SARS-CoV-2 by binding in the binding pocket with docking score ranging from −9.664 to −6.488 kcal/mol and shows drug-like property and also effectively inhibit cytokine storm by antagonizing the TNF-[Formula: see text] and IL-6 receptors. Promising drug-like properties, excellent docking scores, and binding pose against each target makes the screened compounds as possible lead candidate which can be further evaluated in future studies to assess their in vitro and in vivo efficacy against SARS-CoV-2. The structure of these compounds can be used further for optimization and design of drugs against COVID-19.

The core/shell particles were spherical with exact average diameter of them was 66.9nm. EDS showed each Mno.5Zno. 5Fe2O4@Au nanoparticle contained Mn, Zn, Fe, O and Au elements, and this proved Au had successfully attached to Mn0.5Zn0. 5Fe2O4.The result of thermodynamic test showed that Mno.5Zno. 5Fe2O4@Au composite nanoparticles could serve as a heating source under alternating magnetic field (AMF) exposure leading to reach their steady temperature (40-45°C). Moreover, Mno.5Zno. 5Fe2O4@Au composite nanoparticles didn’t show cytotoxicity in vitro. The therapeutic result reveals that Mno.5Zno. 5Fe2O4@Au composite nanoparticles can significantly inhibit the growth of glioma cells.The conclusion was that the self-prepared Mno.5Zno. 5Fe2O4@Au composite nanoparticles had strong magnetic responsiveness and good power absorption capabilities in the high frequency AMF,then they could suggested to be useful for glioma hyperthemia. Mno.5Zno. 5Fe2O4 @Au composite nanoparticles can not only be directed to tumor region in a given magnetic field more exactly but also produce marked thermotherapy.
The Effects of Green Kiwifruit Ingestion on Digestive Health, Blood Flow, Skin Health, and the Autonomic Nervous System

We aimed to assess the impact of consuming two Zespri Hayward green kiwifruit a day on 11 healthy women subjects over a period of 4 consecutive weeks. We analyzed the effects of kiwifruit consumption on intestinal, abdominal, and bowel movement related discomfort, bowel movement frequency, peripheral blood flow, skin health, and autonomic nervous system activity. This study was a randomized control trial, consisting of a four-week intervention period. Participants were divided to ensure equal age distributions and then randomly placed into two intervention groups: a kiwifruit consumption group (n = 11) and a control group (no kiwifruit consumption) (n = 5). The kiwifruit consumption group was instructed to consume two kiwifruit a day during the 4-week intervention period, while subjects in the control group were instructed not to consume kiwifruit for the duration of the study. Besides a restriction from eating yogurt and other fruits, subjects were requested to eat their meals as per usual. The results of this study showed a significant decrease in intestinal, abdominal, and bowel movement discomfort, and a significant increase in bowel movement frequency, at 4 weeks of kiwifruit consumption compared to before consumption. In addition, subjects in the kiwifruit consumption group experienced a significant increase in blood flow, particularly in the index and middle finger at 2 and 4 weeks of kiwifruit consumption. Furthermore, subjects in the kiwifruit consumption group experienced a significant increase in skin brightness at 4 weeks of kiwifruit consumption compared to before consumption. The results of this study suggest that kiwifruit appears to be a delicious and safe option for intestinal, abdominal, and bowel movement discomfort interventions for healthy women. In addition, kiwifruit may aid in increasing bowel movement frequency, peripheral blood flow, and brightness of skin among healthy women as well.
Influence of Soil Saturation on Survival and Growth of Bottomland Oaks Six and Fourteen Years after Planting

Abstract Bottomland oak restoration projects have been marginally successful because professionals often recommend conventional tree-planting procedures that prove problematic in hydric soils. A reliable method of matching oak species to bottomland sites is needed prior to planting. To address the issue, we planted 8 different species of oak seedlings into previously farmed hydric soil in West Tennessee in 2004. We took measurements after 6 and 14 growing seasons to ascertain survival and growth trends based on soil mottling and the depth to gleyed matrix. The later measurements mostly supported early findings that Quercus lyrata (Overcup Oak), Q. texana (Nuttall Oak), Q. palustris (Pin Oak), and Q. phellos (Willow Oak) are most tolerant of poorly drained soil and that as soil drainage improves, species diversity may expand.

Ca-Al-silicate inclusions in natural moissanite (SiC)

Abstract Hundred-micrometer-sized calcium-aluminum-silicates (CAS) inclusions occur in moissanite-4H, moissanite-15R, and moissanite-6H from Turkey. These inclusions commonly consist of tabular exsolution lamellae of two different minerals. By combined electron microprobe and Raman spectroscopy analysis, at least eight different, essentially Mg- and Fe-free Ca-Al-silicate or Al-silicate phases have been discerned. The most common phase is dmisteinbergite, a hexagonal modification of CaAl2Si2O8, occurring in association with lamellae of Cax(Al,Si)1−xO3 or Ca1−x(Al,Si)2+xO5 compositions. All three phases contain significant amounts of BaO (up to 2 mol% of celsiane component in dmisteinbergite), SrO, SO3, and light rare earth elements (LREE). In particular, Ca1−x(Al,Si)2+xO5 contains up to 2.1 wt% of LREE, 3.9 wt% of F, and significant traces of Cl, while it is also associated to osbornite (TiN). Pure ghelenite, Ca2Al2SiO7, and three additional compositions, namely CaAl4–xSixO7, Ca1–x(Al,Si)3+xO6, and Ca3–x(Al,Si)6+xO14 have been found, either occurring as single grains or forming exsolution lamellae. They also contain significant amounts of BaO, SrO, SO3, and LREE. One last intriguing phase is composed in average of 65.9 wt% SiO2, 17.4% Al2O3, 3.0% alkalis, 6.0% BaO, 2.0% CaO+MgO, 0.9% ZrO2, and up to 0.5% LREE. Dmisteinbergite and ghelenite show Raman peaks in very good agreement with literature data, Cax(Al,Si)1–xO3 shows main Raman modes at 416 and 1009 cm−1, Ca1–x(Al,Si)3+xO6 at 531 and 1579 cm−1 while Ca3–x(Al,Si)6+xO14 has a strong peak at 553 cm−1. CaAl4–xSixO7 shows a weak Raman pattern, while Ca1–x(Al,Si)2+xO5 has no detectable Raman modes. Since the association moissanite-CAS is thermodynamically not stable at ambient pressure and moissanite crystals hosting the CAS phases have δ13C values typical of deep-mantle origin, we interpret the CAS inclusions as partially retrogressed HP minerals. Striking analogies exist between observed CAS compositions and experimentally obtained HP-HT mineralogy. For instance, Cax(Al,Si)1–xO3 contains up to 25 mol% of Al2O3, which is considered as the upper limit of alumina solubility in Ca-perovskite. The study confirms that CAS phases are an important mantle depository for large ion lithophile elements (LILE) and LREE.

Influence of zinc and magnesium substitution on ion release from Bioglass 45S5 at physiological and acidic pH

Abstract Ion release of Mg- and Zn-substituted Bioglass 45S5 (46.1 SiO2-2.6 P2O5-26.9 CaO-24.3Na2O; mol%; with 0, 25, 50, 75 or 100% of calcium replaced bymagnesium/zinc) was investigated at pH 7.4 (Tris buffer) and pH 4 (acetic acid/sodium acetate buffer) in static and dynamic dissolution experiments. Despite Mg2+ and Zn2+ having the same charge and comparable ionic radii, they influenced the dissolution behaviour in very different ways. In Tris, Mgsubstituted glasses showed similar ion release as 45S5, while Zn-substituted glasses showed negligible ion release. At low pH, however, release behaviour was similar, with all glasses releasing large percentages of ions within a few minutes. Precipitation of crystalline phases also varied, as Mg- and Zn-substitution inhibited apatite formation, and Zn-substitution resulted in formation of zinc phosphate phases at low pH. These results are relevant for glasses used in aluminium-free glass ionomer bone cements, as they show that Zn/Mg-substituted glasses release ions similarly fast as glasses containing no Zn/Mg, suggesting that these ions are no prerequisite for ionomer glasses. Zn-substituted glasses may potentially be used as controlled-release materials, which release antibacterial zinc ions when needed only, i.e. at low pH conditions (e.g. bacterial infection), but not at normal physiological pH conditions.
