Published: January 2021

Sport is becoming increasingly competitive and athletes are being exposed to greater physical demands, leaving them prone to injuries. Monitoring athletes with the use of wearable technology could provide a way to potentially manage training and competition loads and reduce injuries. One such technology is the VERT inertial measurement unit, a commercially available discrete wearable device containing a 3-axis accelerometer, 3-axis gyroscope and 3-axis magnetometer. Some of the main measurement outputs include jump count, jump height and landing impacts. While several studies have examined the accuracy of the VERT’s measures of jump height and jump count, landing impact force has not yet been investigated. The objective of this research study was to explore the validity of the VERT landing impact values. We hypothesized that the absolute peak VERT acceleration values during a jump-land cycle would fall within 10% of the peak acceleration values derived simultaneously from a research-grade accelerometer (Shimmer). Fourteen elite university-level volleyball players each performed 10 jumps while wearing both devices simultaneously. The results showed that VERT peak accelerations were variable (limits of agreement of -84.13% and 52.37%) and had a propensity to be lower (mean bias of -15.88%) when compared to the Shimmer. In conclusion, the validity of the VERT device’s landing impact values are generally poor, when compared to the Shimmer.
Impact of maternal prenatal stress by glucocorticoids on metabolic and cardiovascular outcomes in their offspring: A systematic scoping review
Authors: Eberle Claudia , Fasig Teresa , Brüseke Franziska , Stichling Stefanie
Published: January 2021

Background

“Stress” is an emerging problem in our society, health care system as well as patient care, worldwide. Especially by focusing on pre-gestational, gestational but also lactation phases “stress” is to be considered as an own trans-generational risk factor which is associated with adverse metabolic as well cardiovascular outcomes in mothers and their children. Hence, the maternal hypothalamic-pituitary-adrenotrophic (HPA) axis may be stimulated by various “stress” mechanisms as well as risk factors leading to an adverse in utero environment, e.g. by excess exposure of glucocorticoids, contributing to cardio-metabolic disorders in mothers and their offspring.

Objective

To review the evidence of in utero programming by focusing on the impact of maternal “stress”, on adverse cardio-metabolic outcomes on their offspring later in life, by identifying underlying (patho-) physiological mechanisms (1) as well as adverse short and long-term cardio-metabolic outcomes (2).

Methods

We conducted a systematic scoping review to identify publications systematically including reviews, interventional, observational, experimental studies as well as human and animal model studies. MEDLINE (PubMed) and EMBASE databases and reference lists were searched. Peer-reviewed articles from January 2000 until August 2020 were included.

Results

Overall, n = 2.634 citations were identified, n = 45 eligible studies were included and synthesized according to their key findings. In brief, maternal hypothalamic-pituitary-adrenotrophic (HPA) axis might play a key role modifying in utero milieu leading to cardio-metabolic diseases in the offspring later in life. However, maternal risk factor “stress”, is clearly linked to adverse cardio-metabolic offspring outcomes, postnatally, such as obesity, hyperglycemia, insulin resistance, diabetes mellitus (DM), Metabolic Syndrome (MetS), cardiovascular disease (CD), hypertension, restricted fetal growth as well as reduced birth, adrenal, and pancreas weights.

Conclusions

Women who experienced “stress” as risk factor, as well as their offspring, clearly have a higher risk of adverse short- as well as long-term cardio-metabolic outcomes. Future research work is needed to understand complex transgenerational mechanisms.

Background and aims

Several studies reported a high incidence of pulmonary embolism (PE) among patients with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection, but detailed data about clinical characteristics, risk factors of these patients and prognostic role of PE are still lacking. We aim to evaluate the occurrence of pulmonary embolism among patients with SARS-CoV-2 infection, and to describe their risk factors, clinical characteristics, and in-hospital clinical outcomes.

Methods

This is a multicenter Italian study including 333 consecutive SARS-CoV-2 patients admitted to seven hospitals from February 22 to May 15, 2020. All the patients underwent computed tomography pulmonary angiography (CTPA) for PE detection. In particular, CTPA was performed in case of inadequate response to high-flow oxygen therapy (Fi02≥0.4 to maintain Sp02≥92%), elevated D-dimer (>0.5μg/mL), or echocardiographic signs of right ventricular dysfunction. Clinical, laboratory and radiological data were also analyzed.

Results

Among 333 patients with laboratory confirmed SARS-CoV-2 pneumonia and undergoing CTPA, PE was detected in 109 (33%) cases. At CTPA, subsegmental, segmental, lobar and central thrombi were detected in 31 (29%), 50 (46%), 20 (18%) and 8 (7%) cases, respectively. In-hospital death occurred in 29 (27%) patients in the PE-group and in 47 (21%) patients in the non-PE group (p = 0.25). Patients in PE-group had a low rate of traditional risk factors and deep vein thrombosis was detected in 29% of patients undergoing compression ultrasonography. In 71% of cases with documented PE, the thrombotic lesions were located in the correspondence of parenchymal consolidation areas.

Conclusions

Despite a low rate of risk factors for venous thromboembolism, PE is present in about 1 out 3 patients with SARS-CoV-2 pneumonia undergoing CTPA for inadequate response to oxygen therapy, elevated D-dimer level, or echocardiographic signs of right ventricular dysfunction. In most of the cases, the thromboses were located distally in the pulmonary tree and were mainly confined within pneumonia areas.

Iterative image reconstruction is widely used in positron emission tomography. However, it is known to contribute to quantitation bias and is particularly pronounced during dynamic studies with 11C-labeled radiotracers where count rates become low towards the end of the acquisition. As the strength of the quantitation bias depends on the counts in the reconstructed frame, it can differ from frame to frame of the acquisition. This is especially relevant in the case of neuro-receptor studies with simultaneous PET/MR when a bolus-infusion protocol is applied to allow the comparison of pre- and post-task effects. Here, count dependent changes in quantitation bias may interfere with task changes. We evaluated the impact of different framing schemes on quantitation bias and its propagation into binding potential (BP) using a phantom decay study with 11C and 3D OP-OSEM. Further, we propose a framing scheme that keeps the true counts per frame constant over the acquisition time as constant framing schemes and conventional increasing framing schemes are unlikely to achieve stable bias values during the acquisition time range. For a constant framing scheme with 5 minutes frames, the BP bias was 7.13±2.01% (10.8% to 3.8%) compared to 5.63±2.85% (7.8% to 4.0%) for conventional increasing framing schemes. Using the proposed constant true counts framing scheme, a stabilization of the BP bias was achieved at 2.56±3.92% (3.5% to 1.7%). The change in BP bias was further studied by evaluating the linear slope during the acquisition time interval. The lowest slope values were observed in the constant true counts framing scheme. The constant true counts framing scheme was effective for BP bias stabilization at relevant activity and time ranges. The mean BP bias under these conditions was 2.56±3.92%, which represents the lower limit for the detection of changes in BP during equilibrium and is especially important in the case of cognitive tasks where the expected changes are low.

Despite its deleterious impact on farming and agriculture, the physiology and energetics of insect migration is poorly understood due to our inability to track their individual movements in the field. Many insects, e.g. monarch butterflies,Danaus plexippus(L.), are facultative migrants. Hence, it is important to establish whether specific insect populations in particular areas migrate. The polyphagous insect,Helicoverpa armigera(Hübner), is especially interesting in this regard due to its impact on a variety of crops. Here, we used a laboratory-based flight mill assay to show thatHelicoverpa armigerapopulations clearly demonstrate facultative migration in South India. Based on various flight parameters, we categorized male and female moths as long, medium or short distance fliers. A significant proportion of moths exhibited long-distance flight behavior covering more than 10 km in a single night, averaging about 8 flight hours constituting 61% flight time in the test period. The maximum and average flight speeds of these long fliers were greater than in the other categories. Flight activity across sexes also varied; male moths exhibited better performance than female moths. Wing morphometric parameters including forewing length, wing loading, and wing aspect ratio were key in influencing long-distance flight. Whereas forewing length positively correlated with flight distance and duration, wing loading was negatively correlated.

Objective

To determine risk factors affecting time-to-death ≤90 and >90 days in children who underwent a modified Blalock-Taussig shunt (MBTS).

Methods

Data from a retrospective cohort study were obtained from children aged 0–3 years who experienced MBTS between 2005 and 2016. Time-to-death (prior to Glenn/repair), time-to-alive up until December 2017 without repair, and time-to-progression to Glenn/repair following MBTS were presented using competing risks survival analysis. Demographic, surgical and anesthesia-related factors were recorded. Time-to-death ≤90 days and >90 days was analyzed using multivariate time-dependent Cox regression models to identify independent predictors and presented by adjusted hazard ratios (HR) and 95% confidence intervals (CI).

Results

Of 380 children, 119 died, 122 survived and 139 progressed to Glenn/repair. Time-to-death probability (95% CI) within 90 days was 0.18 (0.14–0.22). Predictors of time-to-death ≤90 days (n = 63) were low weight (<3 kg) (HR 7.6, 95% CI:2.8–20.4), preoperative ventilator support (HR 2.7, 95% CI:1.3–5.6), postoperative shunt thrombosis (HR 5.0, 95% CI:2.4–10.4), bleeding (HR 4.5, 95% CI:2.1–9.4) and renal failure (HR 4.1, 95% CI:1.5–10.9). Predictors of time-to-death >90 days (n = 56) were children diagnosed with pulmonary atresia with ventricular septal defect and single ventricle (compared to tetralogy of fallot) (HR 3.2, 95% CI:1.2–7.7 and HR 3.1, 95% CI:1.3–7.6, respectively), shunt size/weight ratio >1.1 vs <0.65 (HR 6.8, 95% CI:1.4–32.6) and longer duration of mechanical ventilator (HR 1.002, 95% CI:1.001–1.004). Shunt size/weight ratio ≥1.0 (vs <1.0) and ≥0.65 (vs <0.65) were predictors for overall time-to-death in neonates and toddlers, respectively (HR 13.1, 95% CI:2.8–61.4 and HR 7.8, 95% CI:1.7–34.8, respectively).

Conclusions

Perioperative factors were associated with time-to-death ≤90 days, whereas particular cardiac defect, larger shunt size/weight ratio, and longer mechanical ventilation were associated with time-to-death >90 days after receiving MBTS. Larger shunt size/weight ratio should be reevaluated within 90 days to minimize the risk of shunt over flow.

Published: January 2021

Workload in the nursing profession is high, which is associated with poor health. Thus, it is important to get a proper understanding of the working situation and to analyse factors which might be able to mitigate the negative effects of such a high workload. In Germany, many people with serious or life-threatening illnesses are treated in non-specialized palliative care settings such as nursing homes, hospitals and outpatient care. The purpose of the present study was to investigate the buffering role of resources on the relationship between workload and burnout among nurses. A nationwide cross-sectional survey was applied. The questionnaire included parts of the Copenhagen Psychosocial Questionnaire (COPSOQ) (scale ‘quantitative demands’ measuring workload, scale ‘burnout’, various scales to resources), the resilience questionnaire RS-13 and single self-developed questions. Bivariate and moderator analyses were performed. Palliative care aspects, such as the ‘extent of palliative care’, were incorporated to the analyses as covariates. 497 nurses participated. Nurses who reported ‘workplace commitment’, a ‘good working team’ and ‘recognition from supervisor’ conveyed a weaker association between ‘quantitative demands’ and ‘burnout’ than those who did not. On average, nurses spend 20% of their working time with palliative care. Spending more time than this was associated with ‘burnout’. The results of our study imply a buffering role of different resources on burnout. Additionally, the study reveals that the ‘extent of palliative care’ may have an impact on nurse burnout, and should be considered in future studies.

Published: January 2021

Pyrethroid resistance was first reported in 2013 for the navel orangeworm, Amyelois transitella, but the genetic underpinnings of pyrethroid resistance are unknown. We investigated the role of cytochrome P450 monooxygenases (P450s) belonging to the CYP3 and CYP4 clans using colonies derived from individuals collected in 2016 from almond orchards in two counties. One colony (ALM) originated from an almond orchard in Madera County with no reported pyrethroid resistance and the second colony (R347) originated from the same Kern County orchard where pyrethroid resistance was first reported. We used high-throughput quantitative real-time PCR (qRT-PCR) analyses of 65 P450s in the CYP3 and CYP4 clans of A. transitella to identify P450s induced by bifenthrin and associated with pyrethroid resistance. Nine P450s were constitutively overexpressed in R347 compared to ALM, including CYP6AE54 (11.7-fold), belonging to a subfamily associated with metabolic pesticide detoxification in Lepidoptera and CYP4G89 (33-fold) belonging to a subfamily associated with cuticular hydrocarbon (CHC) synthesis and resistance via reduced pesticide penetrance. Cuticular hydrocarbons analysis revealed that R347 produced twice as many total CHCs in the egg and adult stages as ALM. Topical toxicity bioassays for R347 determined that egg mortality was reduced at low bifenthrin concentrations and larval mortality was reduced at high concentrations of bifenthrin compared to ALM. Our discovery of both changes in metabolism and production of CHCs for R347 have implications for the possible decreased efficacy of other classes of insecticide used to control this insect. The threat of widespread pyrethroid resistance combined with the potential for cross-resistance to develop through the mechanism of reduced penetrance warrants developing management strategies that facilitate insecticide passage across the cuticle.

Intracellular pathogens have evolved to utilize normal cellular processes to complete their replicative cycles. Pathogens that interface with proliferative cell signaling pathways risk infections that can lead to cancers, but the factors that influence malignant outcomes are incompletely understood. Human papillomaviruses (HPVs) predominantly cause benign hyperplasia in stratifying epithelial tissues. However, a subset of carcinogenic or “high-risk” HPV (hr-HPV) genotypes are etiologically linked to nearly 5% of all human cancers. Progression of hr-HPV-induced lesions to malignancies is characterized by increased expression of the E6 and E7 oncogenes and the oncogenic functions of these viral proteins have been widely studied. Yet, the mechanisms that regulate hr-HPV oncogene transcription and suppress their expression in benign lesions remain poorly understood. Here, we demonstrate that EGFR/MEK/ERK signaling, influenced by epithelial contact inhibition and tissue differentiation cues, regulates hr-HPV oncogene expression. Using monolayer cells, epithelial organotypic tissue models, and neoplastic tissue biopsy materials, we show that cell-extrinsic activation of ERK overrides cellular control to promote HPV oncogene expression and the neoplastic phenotype. Our data suggest that HPVs are adapted to use the EGFR/MEK/ERK signaling pathway to regulate their productive replicative cycles. Mechanistic studies show that EGFR/MEK/ERK signaling influences AP-1 transcription factor activity and AP-1 factor knockdown reduces oncogene transcription. Furthermore, pharmacological inhibitors of EGFR, MEK, and ERK signaling quash HPV oncogene expression and the neoplastic phenotype, revealing a potential clinical strategy to suppress uncontrolled cell proliferation, reduce oncogene expression and treat HPV neoplasia.

Infections with Gram-negative bacteria form an increasing risk for human health due to antibiotic resistance. Our immune system contains various antimicrobial proteins that can degrade the bacterial cell envelope. However, many of these proteins do not function on Gram-negative bacteria, because the impermeable outer membrane of these bacteria prevents such components from reaching their targets. Here we show that complement-dependent formation of Membrane Attack Complex (MAC) pores permeabilizes this barrier, allowing antimicrobial proteins to cross the outer membrane and exert their antimicrobial function. Specifically, we demonstrate that MAC-dependent outer membrane damage enables human lysozyme to degrade the cell wall of E. coli. Using flow cytometry and confocal microscopy, we show that the combination of MAC pores and lysozyme triggers effective E. coli cell wall degradation in human serum, thereby altering the bacterial cell morphology from rod-shaped to spherical. Completely assembled MAC pores are required to sensitize E. coli to the antimicrobial actions of lysozyme and other immune factors, such as Human Group IIA-secreted Phospholipase A2. Next to these effects in a serum environment, we observed that the MAC also sensitizes E. coli to more efficient degradation and killing inside human neutrophils. Altogether, this study serves as a proof of principle on how different players of the human immune system can work together to degrade the complex cell envelope of Gram-negative bacteria. This knowledge may facilitate the development of new antimicrobials that could stimulate or work synergistically with the immune system.

La importancia socio económica del turismo y las diversas transformaciones que genera, han aumentado el interés por estudiar sus impactos. Este artículo contribuye a la discusión sobre los procesos de transformación generados por la decisión de cambiar, gestionar, planear el uso del suelo para configurar destinos turísticos. A través de la revisión de 162 artículos escritos desde el año 2000 al 2020, se identificaron y clasificaron impulsores e implicaciones de esta decisión. Encontrando que la mayoría de las investigaciones se desarrollaron en destinos de costa, áreas rurales y áreas protegidas, a escalas locales, con estudios de caso, en países como China, España, México y Turquía, entre otros. El principal impulsor del turismo fue la presencia y disponibilidad de recursos en el destino, que, a través de la formulación de planes y programas y de cambios en la regulación, por parte del gobierno, se convierten en atractivos que favorecen las condiciones para el desarrollo del turismo. La mayoría de los artículos revisados indicaron implicaciones negativas, especialmente asociadas con la degradación de los ecosistemas. Lo anterior, muestra la necesidad de integrar diversos aspectos políticos, económicos, ecológicos,sociales y culturales, en la decisión de adaptar el uso del suelo al desarrollo del turismo.

Proposed Tasks of Enceladus Missions’ Instrumentation in the Context of Their Astrobiological Goals
Authors: Kubiak Katarzyna , Kotlarz Jan , Zalewska Natalia , Zielenkiewicz Urszula
Published: January 2021

Enceladus, Saturnian satellite, is a very significant object for astrobiologists due to the presence of liquid water that forms the ice-covered ocean. Water ice geysers escape from the south pole region through cracks in the ice shield. During the Cassini flight, the probe took samples of plumes matter recognizing besides other methane and molecular hydrogen. Since then, hypotheses have been formulated that life forms similar to those found in the Lost City Hydrothermal Field in the Atlantic ocean bottom may occur near Enceladus’ hydrothermal chimneys. In our work, we analyzed the possibility of a microbial factor detection in the Enceladus geysers. We used as model organisms selected extremophiles. We investigated multi-spectral cameras and mass spectrometers intended for use in mission proposals to Enceladus: Enceladus Orbiter, Enceladus Life Finder, The Explorer of Enceladus and Titan and THEO mission. The review pointed that the configuration of mass spectrometers and the proposed parameters of scientific orbits are appropriate for detecting volatile organic compounds corresponding to selected microorganisms such as aldehyde, ethanol, benzene, toluene, indole, or violacein. The possible presence of a microbiological component with physical dimensions in the order of several micrometres can only be observed for areas of geyser formation at their higher density (> 10 ppm) and with the occurrence of the “snowing microbes” phenomenon. We have found that particularly useful optical channels are 780–975 nm, 860–910 nm, and 5.0–5.3 µm.

Published: January 2021

Several studies have suggested that athletes with disabilities experience more difficulties having access to oral health care than the population in general. The aim of this study was to estimate the impact of socio-demographic/socio-economic factors, oral hygiene habits and clinical oral health conditions on the OHRQoL – Oral Health-Related Quality of Life (assessed with the Oral Health Impact Profile 14 – OHIP-14) on a sample of athletes with heterogeneous types of disabilities. Altogether, 105 athletes with disabilities were evaluated. Cross-sectional data was collected including interviews to obtain socio-demographic/socio-economic data, the OHIP-14 and clinical oral examinations parameters. The outcome variable was the OHIP-14 severity score. The explanatory variables were sex, age, monthly household income, level of schooling, frequency of toothbrushing and flossing, gingival bleeding, periodontal disease, trauma in incisors, prosthesis wearing and needs, number of sound teeth, DFMT (decayed, filled and missing teeth) index and its isolate components. Mann-Whitney, Kruskall-Wallis and Spearman tests used to compare OHIP-14 severity scores associated with the explanatory variables. The mean OHIP-14 severity score for the sample was 9.32 (SD 8.99) and the most affected domain was Physical Pain (mean 2.63; SD 1.97), followed by Psychological Discomfort (mean 1.81; SD 2.02). Significant differences in mean OHIP-14 scores were found for periodontal disease, need for complete dentures, number of sound teeth, DFMT index and its components. These results suggest that these clinical parameters can be related to impaired OHRQoL for this population.

Objetivo: delinear a distribuição e caracterização da lagoquilascaríase no Pará com base nos casos descritos na literatura. Métodos: Revisão Sistemática da Literatura somada à Revisão Integrativa da Literatura, realizando buscas na base de dados Google Acadêmico, Scielo Brasil, Periódicos Capes, Lilacs, Medline e PubMed de publicações sobre a lagoquilascaríase, entre 1978-2018. Resultados: foram encontradas 17 publicações, as quais constaram 44 casos descritos, oriundos do Pará, sendo que a maioria deles ocorreram em municípios da porção sudeste do estado, principalmente nos de Marabá e Xinguara, e demais municípios entornos. Além disso, ficou nítida uma maior quantidade de casos entre os anos 80 e 90, com queda brusca a partir de 2000, o que possivelmente se justifica pela falta de ocorrência ou de diagnóstico de novos casos. Conclusão: a partir de um melhor delineamento da distribuição de casos em pontos específicos no estado, podem ser elaborados estudos para essas localidades por meio de instituições de ensino e saúde, com o intuito de sanar dúvidas sobre a lagoquilascaríase.

Problemas de coexistencia entre Denominaciones de Origen Protegidas e Indicaciones Geográficas Protegidas: El caso “Aceite de Jaén”
Authors: Sánchez Jaraba José Ramón
Published: January 2021

Designations of Origin and Geographical Indications are two quality titles covered by EU legislation for the protection of agricultural products and foodstuffs whose quality is linked to a specific territory. In spite of being two different titles, the similarities between them are evident, and, since the EU regulations do not establish priority or incompatibility between them, it is possible that both protection instruments can apply in the same territory to designate the same type of product. This is actually the case in the province of Jaén, in southeastern Spain, where three Protected Denominations of Origin (PDOs) are threatened as a result of the application for registration of a Protected Geographical Indication (PDI) that intends to act at the provincial level for designating the same product: extra virgin olive oil. In this study we analyse this case and formulate some general recommendations of possible solutions that might allow a peaceful coexistence between these two titles of protection.

On finitely generated submonoids of virtually free groups
Authors: Silva Pedro V. , Zakharov Alexander
Published: January 2021

We prove that it is decidable whether or not a finitely generated submonoid of a virtually free group is graded, introduce a new geometric characterization of graded submonoids in virtually free groups as quasi-geodesic submonoids, and show that their word problem is rational (as a relation).
We also solve the isomorphism problem for this class of monoids, generalizing earlier results for submonoids of free monoids.
We also prove that the classes of graded monoids, regular monoids and Kleene monoids coincide for submonoids of free groups.
Trade and the size distribution of firms: Evidence from the German Empire
Authors: Biermann Marcus
Published: January 2021

What effect did trade have on the size distribution of firms during the first wave of globalization? Three historical datasets from the German Empire between 1875 and 1907 were collected and harmonized to answer this question. This paper combines industry census and bilateral railway trade data from the same industry and region along with industry-level tariff data. The evidence shows that increases in aggregate trade caused the share of firms to shift from smaller to larger firms. Exogenous decreases in tariffs caused an increase in the share of the largest firms. The regional distributive effects of trade on inequality between firms that are discussed in the contemporaneous literature were already present during the first wave globalization.
The consistent criteria for hypotheses testing
Authors: Purtukhia Omar , Zerakidze Zurab

In this paper, we define consistent criteria for hypotheses testing, such that the probability of any kind of error is zero for a given criterion. The necessary and sufficient conditions for the existence of such criteria are given.
Genetic variation of microfibril angle and its relationship with solid wood and pulpwood traits in two progeny trials of Eucalyptus nitens in Tasmania
Authors: Rocha-Sepúlveda Manuel F. , Williams Dean , Vega Mario , Harrison Peter A. , Vaillancourt René E. , Potts Brad M.
Published: January 2021

Microfibril angle (MFA) is a key biological trait contributing to wood stiffness, which is a common breeding objective for solid wood products in many tree species. To explore its genetic architecture, area-weighted MFA was measured in two Eucalyptus nitens progeny trials in Tasmania, Australia, with common open-pollinated families. Radial strips were extracted from 823 trees in 131 families and MFA assessed using SilviScan-2®. Heritability, genotype-by-environment interaction and inter-trait genetic correlations were evaluated to examine the genetic variability and stability of MFA and its relationships with other solid wood and pulpwood selection traits. Significant family variation was found for MFA in both trials. There was no significant genotype-by-environment interaction and the across-site narrow-sense heritability was 0.27. MFA was genetically independent of basic density, growth, and tree form. However, MFA was strongly and favourable genetically correlated to acoustic wave velocity in standing trees, modulus of elasticity and kraft pulp yield (KPY). The present study has shown that genetic improvement of E. nitens for pulpwood selection traits is unlikely to have adversely affected MFA, and thus timber stiffness. Rather these results suggest the possibility that selection for increased KPY may have indirectly improved MFA favourably for solid wood products.
Reading Esther as a Postcolonial Feminist Icon for Asian Women in Diaspora
Authors: Hatzaw Ciin Sian Siam
Published: January 2021

The book of Esther has been the subject of a wealth of scholarship which has, at times, presented Esther’s character as antifeminist. Through the framework of postcolonial and feminist theory, this article interprets Esther in light of her marginalised identity. Her position as a Jewish woman in diaspora who must hide her ethnicity and assimilate into Persian culture reveals parallels to contemporary Asian women in Western diaspora, due to perpetuated stereotypes of passiveness and submission, and the model minority myth associated with Asian immigration. Esther’s sexualisation reveals further parallels to the fetishisation and sexual exploitation of Asian women. If we read the text in light of her marginalisation, we can highlight the racial and gendered oppression within the existing power structures, as well as the levels of privilege at work within the character dynamics. Esther serves as an example of the potential that lies in recognising positions of privilege, the implications of identity, and understanding different forms of resistance in order to form a liberative theology. This article outlines the position of Asian women and their proximity to whiteness in relation to other BIPOC (black, indigenous, and people of colour) communities, revealing unexpected connections to Esther’s character. By situating Esther within intersectional and interdisciplinary theory, her status as a postcolonial feminist icon emerges. Through her story, Asian women in diaspora may find their experiences reflected in the journey to liberation.

Phenomenal Simulation Modelling of X-Ray Diffraction Patterns of Pyrite Ash Bioprocessed in Acetobacter aceti Contained Media
Authors: Ermurat Yakup
Published: January 2021

Phenomenal profiling functions were applied for the simulation of an X-ray diffraction (XRD) pattern of pyrite ash bioprocessed in Acetobacter aceti contained growth media. The full width at half maximum (FWHM) values were estimated for each pattern of pyrite ash, and the Bragg equation was used to determine the atomic layer spacing, as well crystallite size and strain broadening were accomplished by applications of Scherrer and Williamson-Hall equations. Errors in line broadening were correlated with the FWHM equations of the generalised profiling functions, and the microstrain (ε) was estimated with the relation between the integral breadth (βi) and cosθ. Furthermore, the XRD pattern of a discrete peak was 3D simulated using Gaussian, Lorentzian, Pearson VII, pseudo-Voigt, and Voigt functions. The Gaussian function with a round top peak was designated the most suitable profile simulation by offering the maximum peak height, Imax and tails comparable to the experimental peak.
Types of trigonometric points in Slovenia
Authors: Triglav Čekada Mihaela , Jenko Marjan
Published: January 2021

In this paper, the historical development context of the trigonometric network point types in Slovenia from 1810 onwards is presented. Examples of different trigonometric point types still seen in the field are shown, with regard to the institution that carried out the field marking of the specific state trigonometric network. The city trigonometric network of Ljubljana, which was established in 1955–1956, is also presented. Furthermore, triangulation and comparator bases are mentioned as well, which remain marked with permanent pillars. As examples of the oldest still-standing trigonometric points, the following are mentioned: 303 Veliki Javornik (2nd order) with the engraved year 1823 and 329 Limberk (2nd order) with the engraved year 1903.
