Gibberellic Acid 4+7 Influences Shoot Growth of Seedling Pecan and Bitternut Hickory
Authors: Miller Brandon M. , Bassuk Nina L.
Published: July 2022

Shoot development of seedling hickories is slow, limiting their success as viable crops using standard growing techniques. Because hickories are predominantly propagated by seed, we questioned whether gibberellic acid (GA) could be used on seedlings to overcome slow shoot development during juvenility. Treatments of one-year-old seedlings of bitternut hickory [Carya cordiformis (Wangenh.) K. Koch], pignut hickory [C. glabra (Mill.) Sweet], pecan [C. illinoinensis (Wangenh.) K. Koch], kingnut hickory [C. laciniosa (F. Michx.) Loud.], shagbark hickory [C. ovata (Mill.) K. Koch], and mockernut hickory [C. tomentosa (Lam.) Nutt.] began at bud break by applying a solution of 500 ppm GA4+7 dissolved in 95% ethanol directly to apical buds or stem tissue at three-day intervals for 27 days. After 160 days, neither treatment affected caliper of any taxon, although species differences were observed. Compared to nontreated control plants, treatment of buds resulted in a 234% and 144% increase in shoot height of bitternut hickory and pecan, respectively. In a second experiment, the same treatments were implemented on seedlings of bitternut hickory shortly after germination. Only shoot height and dry weight were affected (increased) by application of GA4+7. This study indicates plant growth regulators could be effective at increasing shoot extension of some hickories.

Chemicals used in this study: Gibberellic acid 4+7 (GA4+7).

Species used in this study: bitternut hickory [Carya cordiformis (Wangenh.) K. Koch]; pignut hickory [C. glabra (Mill.) Sweet]; pecan [C. illinoinensis (Wangenh.) K. Koch]; kingnut hickory [C. laciniosa (F. Michx.) Loudon]; shagbark hickory [C. ovata (Mill.) K. Koch]; and mockernut hickory [C. tomentosa (Lam.) Nutt.].

Expression of serum soluble Klotho protein in patients with renal damage induced by anti-neutrophil cytoplasmic antibody-associated small-vessel vasculitis and influence on prognosis
Authors: Ma Feiju , Li Jianfei
Published: July 2022

Background: Anti-neutrophil cytoplasmic antibody-associated small-vessel vasculitis (AASV) is an autoimmune disease with unclear pathogenesis, which causes damage to multiple organs and systems, renal failure or even death. We aimed to explore the expression of serum soluble Klotho protein in patients with AASV-induced renal damage and influence on prognosis.

Methods: A total of 330 AASV patients treated from June 2012 to June 2014 were divided into renal damage and non-renal damage groups. Clinical symptoms and laboratory examination results were compared. They were divided into Klotho <935.05 pg/mL and ≥935.05 pg/mL groups, and renal damage and pathological indices were compared. Survival curves were plotted using Kaplan-Meier method, and 5-year and renal survival rates were compared.

Results: Compared with the non-renal damage group, the mean arterial pressure, urine protein and blood creatinine levels significantly rose, while the red blood cell count, hemoglobin, serum albumin, and Klotho protein levels declined in the renal damage group (P<0.05). The optimal cut-off value of Klotho protein in assessing renal damage was 935.05 pg/mL. Compared with Klotho ≥935.05 pg/mL group, the levels of blood creatinine and urine protein significantly increased, and the proportion of normal glomeruli decreased, while that of fibrous crescents rose in Klotho <935.05 pg/mL group (P<0.05). The 5-year renal survival rate was significantly lower in Klotho <935.05 pg/mL group than that in Klotho ≥935.05 pg/mL group (P<0.05).

Conclusions: Klotho protein is lowly expressed in patients with renal damage induced by AASV as a potential marker for early diagnosis and prognostic evaluation.

Published: July 2022

Introduction. In recent years, much attention has been paid to the study of extracellular microparticles (microvesicles and exosomes) and their role in the pathogenesis of human diseases.

The objective of this study was to determine the number and size of plasma extracellular microparticles (PEMP) in patients with severe and extremely severe COVID-19 and correlate these data with the markers of hemostasis activation, inflammation, and tissue damage.

Methods and Materials. The study included 29 patients with severe and extremely severe COVID-19. Concentration and size of PEMP were determined by nanoparticle trajectory analysis (NTA). All patients underwent the complete blood count and the thromboelastometry (TEM). Hemostatic, biochemical, and immunological parameters were assessed including fibrinogen, prothrombin time, activated partial thromboplastin time, D-dimer, C-reactive protein, lactate dehydrogenase, procalcitonin, von Willebrand factor antigen, interleukin 6, and interleukin 18.

Results. There were 14 patients (48.3 %) discharged from the ICU with improvement (group 1— survived patients), and 15 patients (51.7 %) with lethal outcomes (group 2 — lethal outcome); the PEMP concentration did not differ between these groups. In group 2, there were heterogeneity of PEMP population, and a tendency to the larger PEMP size (p=0.074). In all patients, the PEMP concentration correlated negatively with both prothrombin time and the number of large platelets; the size of PEMP correlated negatively with the level of von Willebrand factor antigen, and positively with the fibrinogen. In group 1, the PEMP concentration had a direct correlation with both the level of interleukin 18 and maximum clot lysis in TEM; the PEMP size had a direct correlation with the maximum clot lysis in TEM and an inverse correlation with both the level of procalcitonin and maximum clot density in TEM.

Conclusion. Our study confirms the importance of the process of extracellular microparticles formation in the COVID-19 pathogenesis. Our findings are consistent with the hypothesis that the parameters of PEMP population can be predictive biomarkers of the COVID-19 severity.

Technology, as one component of agroindustry development system, has a strategic role. It can only be realized if new technology is difussed and adopted. Adoption of technology in the processing of white pepper is still very low. It is therefore necessary to study with the aim to develop a model of agroindustry technology adoption process, and to formulate strategic policy for its acceleration. Model of measuring and predicting user acceptance of new technology is adopted from Unified Theory of Acceptance and Use of Technology (UTAUT) model. Mapping and prediction model technology adoption rates are expressed as a form of usage behavior. The model consists of two parts sub models namely intention to use sub models and support facilities sub model. To deal with vagueness in analysis of technology adoption, fuzzy inference system is used on mapping and level prediction of technology adoption.Keywords: technology, process, model, fuzzy inference system, agroindustry
Dispatch model for analysing the impacts of electric vehicles charging patterns on power system scheduling, grid emissions intensity, and emissions abatement costs
Authors: Oliyide Rilwan O. , Cipcigan Liana M.
Published: July 2022

Dispatching of generating resources at Power Stations is a complex task based on the balance of economics, contractual agreement, regulations, and environmental consciousness in terms of emissions produced in the course of electricity generation. The complexity of the task could be exacerbated with the integration of a large percentage of Electric Vehicles (EVs) in the quest to reduce CO2 emissions in the transportation sector. In this paper, a dispatch model, which is suitable for analysing the impacts of charging patterns of EVs on grid emissions intensity and emissions abatement costs, is described and developed for dispatching generating resources/technologies. The dispatch model is based on the correlation between historical system load and capacity factors of generating units. The dispatch model is tested on data from the UK power system on a typical winter day in December 2015 with an assumed 50% integration of EVs on the system. Results show amongst others that charging of EVs in the off-peak period may affect the optimal deployment of generating technologies/resources with storage capacity and could produce a higher average grid emissions intensity.

Electrochemical conditioning via chronopotentiometry (CP) and cyclic voltammetry (CV) is essential for the activation of oxygen evolution reaction (OER) electrocatalysts. While many reports have activated OER electrocatalysts using either CP or CV, the inherent differences between these two electrochemical conditioning methods for the activation of OER electrocatalytic materials have yet to be explored. Here, we investigate the effects of CP and CV electrochemical conditioning on a Ni-based OER precatalyst and substrate in Fe-purified and Fe-unpurified KOH electrolytes by employing (ⅰ) Ni foil, (ⅱ) NiSe precatalyst films with different thicknesses on the fluorine-doped tin oxide glass substrate, and (ⅲ) NiSe precatalyst films on Ni foil substrates. It was found that CV electrochemical conditioning can result in a higher degree of in situ oxidation and Fe incorporation for Ni-based precatalysts and substrates compared to CP electrochemical conditioning. In turn, this brought about different material properties (e.g., in situ oxidized layer thickness, composition, crystallinity, and morphology) and electrochemical characteristics (e.g., active surface area, electron transport limitation, and intrinsic activity) of Ni-based electrocatalysts, thereby not only affecting their OER activity but also complicating the interpretation of the origin of OER activity. This study identifies the distinct effects of CP and CV electrochemical conditioning on Ni-based OER electrocatalysts and provides insight into the choice of the electrochemical conditioning method to better investigate OER electrocatalysts.

Published: July 2022

New methodologies to unite amines and carboxylic acids that complement the popular amide coupling can significantly expand accessible chemical space because they yield products distinct from the classic R–NHC(O)–R’ amide arrangement. Here we have developed an amine–acid esterification reaction based on pyridinium salt activation of amine C–N bonds to create products of type R–OC(O)–R’ upon reaction with alkyl and aryl carboxylic acids. The protocol is robust and facile, as demonstrated by automation on open-source robotics.
Arene C–H Borylation Strategy Enabled by a Non-Classical Boron Cluster-Based Electrophile

Published: July 2022

Introducing a tri-coordinate boron-based functional group (e.g., boronic ester) into an unactivated C–H bond in the absence of directing groups is an ongoing challenge in synthetic chemistry. Despite previous developments in transition metal-catalyzed and -free approaches, C–H borylation of sterically hindered arenes remains a largely unsolved problem to date. Here, we report a synthetic strategy of a precious metal-free electrophilic C–H borylation of sterically hindered alkyl- and haloarenes to generate aryl boronic esters. The reported approach consists of two simple steps that can be carried out under open flask conditions. The first step relies on electrophilic aromatic substitution (SEAr) induced by cage-opening of Cs2[closo-B10H10], forming a 6-Ar-nido-B10H13 product containing a B–C bond. This is followed by an unprecedented cage deconstruction of arylated decaboranes promoted by diols leading to selective breakage of B–B bonds in the cluster while preserving the B–C bond. The combination of these two steps allows for the preparation of aryl boronic esters that are hard-ly accessible by current direct C–H borylation approaches. Unlike the previous arene C–H borylations, this reaction does not require any precious metals, highly-engineered ligands, pre-functionalized boron reagents, or inert conditions. In addition, the unique properties of a non-classical boron cluster electrophile intermediate, B10H13+, afforded an unprecedented regi-oselectivity with unique steric and electronic control without the undesirable side reactions common in electrophilic aro-matic substitution. This work showcases how inorganic cluster chemistry can be leveraged to access new modes of reactivi-ty relevant to organic synthesis.

Published: July 2022

The synthesis of kinetically-stabilized, i.e., metastable, dielectric semiconductors, represents a major frontier within key technologically-important fields as compared to thermodynamically-stable solids that have received considerably more attention. Of longstanding theoretical interest are Sn(II) perovskites (e.g., Sn(Zr1/2Ti1/2)O3, SZT), which are Pb-free analogues of (Pb(Zr1/2Ti1/2)O3, PZT), a commercial piezoelectric composition that is dominant in the electronics industry. Herein, we describe the synthesis of this metastable SZT dielectric through a low-temperature flux reaction technique. The SZT has been found, for the first time, to grow and to be stabilized as a nanoshell at the surfaces of Ba(Zr1/2Ti1/2)O3 (BZT) particles, i.e., forming as BZT-SZT core-shell particles, as a result of Sn(II) cation exchange. In situ powder X-ray diffraction (XRD) and transmission electron microscopy data show that the SZT nanoshells result from the controlled cation diffusion of Sn(II) cations into the BZT particles, with tunable thicknesses of ~25 nm to 100 nm. The SZT nanoshell is calculated to possess a metastability of ~ 0.5 eV atom–1 with respect to decomposition to SnO, ZrO2, and TiO2, and thus cannot currently be prepared as stand-alone particles. Rietveld refinements of the XRD data are consistent with a two-phase BZT-SZT model, with each phase possessing a generally cubic perovskite-type structure and nearly identical lattice parameters. Mössbauer spectroscopic data (119Sn) are consistent with Sn(II) cations within the SZT nanoshells and an outer ~5 to 10 nm surface region comprised of oxidized Sn(IV) cations from exposure to air and water. The optical band gap of the SZT shell was found to be ~2.2 eV, which is redshifted by ~1.2 eV as compared to BZT. This closing of the band gap was probed by X-ray photoelectron spectroscopy and found to stem from a shift of the valence band edge to higher energies (~1.07 eV) as a result of the addition of the Sn 5s2 orbitals forming a new higher-energy valence band. In summary, a novel synthetic tactic is demonstrated to be effective in preparing highly metastable SZT and representing a generally useful strategy for the kinetic stabilization of other predicted, metastable dielectrics.

The Repurposed Pantomime: Exploiting aesthetic distance and playfulness via Brechtian dialectics to engage young adult audiences
Authors:   , Jacob Shekinah
Published: July 2022

This thesis seeks to explore the dramaturgical approaches and outcomes related to a pantomime created especially for young adults (aged 13 to 20). The theoretical aspect of the thesis looks at pantomime through the lens of dramaturgy, psychology and cognitive science i.e. the propensity for the pantomime to be subversive in form and content- its light hearted entertainment value masking the multi-layered avenues for political and social commentary, the aesthetic distance it maintains with the audience for Brechtian engagement, its live audience participation techniques to create agency- all of which could be potentially exploited to attract (as willing audiences) and engage young adults (YA).

I then attempt to use these dramaturgical features as creative strategies to write an original script, experimenting with the form and content to arrive at my own interpretation of what such a play with pantomime features might look like in the modern context and syntax of performances that appeal to YA audiences today. As the script of my creative component progresses through three successive workshops, I document my dramaturgical journey to find the complex balance between plot-driven storytelling to create an emotional connection, and framing to create Brechtian Verfremdungseffekt. I emulate the subversive spirit of the precursor to the pantomime, the commedia dell’arte, as I seek to create active engagement by incorporating dialectics in both form and content to achieve Brechtian distancing. I achieve this by discovering liminal overlapping dramaturgical spaces between connection and disconnection, repurposing dialectical features of the pantomime, and embedding deeper layers and themes within the script.

Through the creative component of this performance as research project, I attempt to assess whether these strategies might grab the attention of YA audiences and induce them out of their technologically engineered virtual worlds in order to engage with the ideas on stage and give them a sense of agency in the world at large.
