Parodies of Religious Hymns in Žemaitijan Carnival: Social Interaction and Cultural Expression: Everyday Life, Festivities and Ritual Forms
Authors:   Klaipėda University, Petrošienė Lina
Published: December 2021

On costumed processions in Žemaitija on Shrove Tuesday, the ‘beggars’ were and are among the main characters, as attested by the mask’s distribution area, the name ‘Shrovetide beggars’ being given to the whole band of masked people, and the relative abundance of the costumed “beggars”’ songs. This study examines some examples from the repertoire of Shrove Tuesday carnival songs in Žemaitija, parodies of religious hymns and folk songs, which the performers called hymns and which were performed in imitation of sacred singing. The present analysis identifies their features, origins and function at the Shrove Tuesday carnival.
Ability to detect antibodies to beak and feather disease virus in blood on filter paper decreases with duration of storage
Authors: Blanch-Lázaro Berta , Ribot Raoul F.H. , Berg Mathew L. , Alexandersen Soren , Bennett Andrew T.D.
Published: December 2021

Background

Beak and feather disease virus (BFDV) is a circovirus that infects captive and wild psittacine birds, and is of conservation concern. The haemagglutination inhibition (HI) assay is used to determine antibody titres against BFDV, and the use of dried blood spots (DBS) on filter paper stored at room temperature has been suggested to be an equally valid technique to the use of frozen serum. However, research on other pathogens has found variable results when investigating the longevity of antibodies stored on DBS at room temperature. Consequently, we aimed to test the temporal stability of antibodies to BFDV in DBS samples stored long-term at room temperature. A further goal was to add to the current knowledge of antibody response to naturally acquired BFDV infection in crimson rosellas (Platycercus elegans).

Methods

Blood was collected from wildP. elegansin Victoria, Australia, that had been live-trapped (n= 9) or necropsied (n= 11). BFDV virus load data were obtained from blood stored in ethanol by real-time quantitative PCR (qPCR); antibody titres were obtained by HI assay from either DBS or serum samples, which had been collected concurrently. All HI assays were performed commercially by the Veterinary Diagnostic Laboratory (VDL) in Charles Sturt University, Australia, who were blind to BFDV blood status.

Results

HI titres from DBS stored at room temperature declined significantly over time (~80 weeks). By contrast, frozen serum samples assayed after 80 weeks in storage all had high HI titres, only varying up to one dilution step from the initial HI titres obtained from DBS at 3–6 weeks after sampling. Weak HI titres from DBS samples all came back negative when the test was repeated only nine weeks later. Novel high HI titres were reported inP. elegans, and while most birds with high antibody titres had corresponding negative qPCR results, a single subadult presented with high HI titres and virus load simultaneously.

Conclusion

Detection of antibodies on filter paper stored at room temperature decreases over time, increasing the chances of false negatives in these samples, and in repeated testing of samples with weak HI titres. Consequently, serum should be the preferred sample type to use for seroepidemiological studies on BFDV in parrots and other bird species. When not possible, it may help to store DBS on filter paper at −20 °C or lower. However, prompt testing of DBS samples (e.g., <6 weeks in storage) is recommended pending further research on antibody temporal stability. We also show thatP. elegans, especially adults, can produce high antibody titres against BFDV, which may help them resist infection.
Light intensity drives different growth strategies in two duckweed species:Lemna minorL. andSpirodela polyrhiza(L.) Schleiden
Authors: Strzałek Małgorzata , Kufel Lech
Published: December 2021

Duckweed speciesLemna minorandSpirodela polyrhizaare clonal plants with vegetative organs reduced to a frond and a root inL. minoror a frond and several roots inS. polyrhiza. They reproduce vegetatively by relatively rapid multiplication of their fronds. The habit ofS. polyrhiza(large fronds with up to 21 roots) makes it a strong competitor among representatives of the family Lemnaceae, probably due to different resource-use strategies compared to small duckweed. In our study, light was the resource that affected the plants before and during the laboratory experiment. We sampled the plants from natural habitats differing in light conditions (open and shady) and grew them for 16 days in a thermostatic growth room at 22 °C under a 16:8 photoperiod and three light intensities (125, 236, 459 µmol photons m–2s–1) to investigate the trade-off between frond enlargement and multiplication. Both species from the open habitat had higher growth rates based on the frond numbers and on surface area of fronds compared to plants from the shady habitat. They adopted different species-specific strategies in response to the experimental light conditions. The species size affected the growth rates inL. minorandS. polyrhiza.Spirodela polyrhizagrew slower thanL. minor, but both species grew fastest at medium light intensity (236 µmol m–2s–1).Lemna minormaintained the growth rates at high light intensity, whileS. polyrhizaslowed down.Spirodela polyrhizaresponded to deteriorating light conditions by increasing its frond surface area, thus optimising light capture.Lemna minorfrom the shady habitat enhanced light harvest by increasing chlorophyllaconcentration, but did not invest more in frond enlargement thanL. minorfrom the open habitat. Under shady conditions,S. polyrhizais likely to achieve an advantage overL. minordue to the larger frond size of the former. Our findings suggest the existence of a trade-off between size and number in duckweed.

In India, dairy farming is traditionally practiced enterprise as a supplementary income source with the crop production. The present study was undertaken to analyze the Economic feasibility of Self-Help Groups (SHGs) microfinance for dairy enterprise run by women particularly from buffalos in Marathwada region of Maharashtra state. Whole study was based on the primary data set which was collected from the Parbhani district for year 2015-16. Multistage sampling design was used in selection of district, tehsils, villages and SHG groups. The cross sectional data was randomly collected from the 70 members of buffalo rearing selected SHGs. So the required data was collected by personal interview method using pre tested schedules. The data collected was subjected to tabular and economic feasibility analysis i.e., Net Present Value (NPV), Benefit-Cost Ratio (B/C ratio), Internal Rate of Return (IRR) and Net benefit – investment ratio (N/K ratio). The study revealed that the net present value was found positive and benefit cost ratio more than unity. The internal rate of return was higher than bank rate. So in the study area dairy is feasible enterprise and very much suitable for rural women to practice and empower them economically and socially. This feasibility analysis showed that dairy enterprise through microfinance gives more returns to women entrepreneurs. So, the financial institutions and NGOs should come forward to extent economic support and guidance to rural women through SHGs to take up these enterprises as an income generating activity.

Published: December 2021

Fish is used as a great source of food and the quality of its meat can be indicated by fat and protein contents as well as low quantity of water in fish meat. Therefore, the present study was performed for improvement in weight, feed-conversion ratio, protein-efficiency ratio, and growth. The experiment was performed at commercial level in field (pond) and the influence of fish meal protein on growth of Labeo rohita was investigated in 60 days culture trials. 90 fingerlings (Size: 4.97 to 6.04; Weight: 4.15 to 4.20) were maintained in well aerated 280 L three glass tanks in triplicate. These glass tanks were named as T1, T2 and T3. T1 was consisted of 30% crude protein with control diet containing proteins, fats vitamins and fibres, T2 consisted of 35% protein with control diet, while T3 consisted of only control diet (rice polish). The fish were fed 4% percent of their body weight twice a day at twelve hours interval for 60 days. There was a significant increase (p<0.05) in body weight, feed-conversion ratio, protein-efficiency ratio, and gross fish production of fish having 35% fish meal protein with control diet (T2) when compared with 30% fish meal protein with control diet T1 and control diet T3. These findings suggest that 35% fishmeal protein appear to be sufficient for obtaining optimum growth in fish.

Authors: Piplani Ankita , Ganadhipathi G. , Sajjan M. C. Suresh
Published: December 2021

Purpose:  To evaluate the reliability of the visibility of the central incisor & the canine for the cervico incisal positioning of anterior maxillary teeth related to age & sex while the upper lip was in repose in dentate patients & the development of rehabilitation recommendations for edentulous individuals with regard to the location of the maxillary incisal edge

Methodology: 308 subjects [152 Males & 156 Females] belonging to the age of 30 to 59 years were selected using a simple stratified random technique. There were three age and sex groups: Group I was 30 to 39 years old, Group II was 40 to 49 years old, and Group III was 50 to 59 years old. The vertical distances (in mm) between the lower border of the upper lip and the right maxillary central incisal edge and canine tip were measured and recorded using adhesive tape marked with millimetres. A single examiner recorded all the measurements and the values were tabulated and subjected to statistical analysis.

Results: Men in Groups I and II had maxillary central incisor exposure ranging from +6 to -1mm, whereas males in Group III had exposure ranging from +5 to -2mm. There was an exposure range of +6 to -2 mm in females in Group I, +7 to -2 mm in Group II, and +5 to -2 mm in Group III for the central incisors. While the canine exposure in Group I and II and Group III ranged from +2 to -4mm in females, the exposure ranged from +3 to -3mm in men of all ages. In all groups, females had statistically significant (P0.05) more central incisor and canine exposure than men.

Conclusions: The canine visibility was less variable in all the age groups and in both males and females in comparison to the central incisor. When restoring edentulous individuals, the average canine exposure dimension can be employed for cervico-incisal location of the anterior maxillary teeth.

A Mechanically Reliable Transparent Antifogging Coating on Polymeric Lenses
Authors: Sun Ye , Rawat Rajdeep Singh , Chen Zhong
Published: December 2021

Polymeric lenses have been increasingly used to replace glass lenses due to advantages of light weight, high refractive index, and ease of making into complicated shapes. However, a severe constraint to their wider application lies with their intrinsic weakness in hardness that can lead to mechanical damages by abrasion. During service, fogging remains another unsolved challenge to optical lenses, which may significantly reduce the users’ visibility or even cause accident. Therefore, it is imperative to develop mechanically reliable and transparent antifogging coating on polymeric lenses. In this work, a two‐step protocol is developed comprising a room‐temperature oxygen plasma treatment of polymer substrate followed by antifogging silica thin film deposition using pulsed laser deposition (PLD). The oxygen plasma treatment modifies the surface chemistry to allow a strong adhesion between the polymer substrate and the silica coating. Due to the porous nature of the PLD deposited nanosilica film, the coating also displays an antireflection effect. This mechanically reliable and highly transparent superhydrophilic silica coating opens great opportunity for the eyewear and high precision optics industries.

Published: December 2021

Cancer immunotherapy has achieved promising clinical progress over the recent years for its potential to treat metastatic tumors and inhibit their recurrences effectively. However, low patient response rates and dose‐limiting toxicity remain as major dilemmas for immunotherapy. Stimuli‐responsive nanoparticles (srNPs) combined with immunotherapy offer the possibility to amplify anti‐tumor immune responses, where the weak acidity, high concentration of glutathione, overexpressions of enzymes, and reactive oxygen species, and external stimuli in tumors act as triggers for controlled drug release. This review highlights the design of srNPs based on tumor microenvironment and/or external stimuli to combine with different anti‐tumor drugs, especially the immunoregulatory agents, which eventually realize synergistic immunotherapy of malignant primary or metastatic tumors and acquire a long‐term immune memory to prevent tumor recurrence. The authors hope that this review can provide theoretical guidance for the construction and clinical transformation of smart srNPs for controlled drug delivery in synergistic cancer immunotherapy.
Respective Roles of Inner and Outer Carbon in Boosting the K+ Storage Performance of Dual‐Carbon‐Confined ZnSe
Authors: Ruan Jiafeng , Zang Jiahe , Hu Jiaming , Che Renchao , Fang Fang , Wang Fei , Song Yun , Sun Dalin
Published: December 2021

Potassium‐ion batteries (PIBs) have been considered as potential alternatives for lithium‐ion batteries since there is a demand for better anode with superior energy, excellent rate capability, and long cyclability. The high‐capacity zinc selenide (ZnSe) anode, which combines the merits of conversion and alloying reactions, is promising for PIBs but suffers from poor cyclability and low electronic conductivity. To effectively boost electrochemical performance of ZnSe, a “dual‐carbon‐confined” structure is constructed, in which an inner N‐doped microporous carbon (NMC)‐coated ZnSe wrapped by outer‐rGO (ZnSe@i‐NMC@o‐rGO) is synthesized. Combining finite element simulation, dynamic analysis, and density functional theory calculations, the respective roles of inner‐ and outer‐carbon in boosting performance are revealed. The inner‐NMC increased the reactivity of ZnSe with K+ and alleviated the volume expansion of ZnSe, while outer‐rGO further stabilized the structure and promoted the reaction kinetics. Benefiting from the synergistic effect of dual‐carbon, ZnSe@i‐NMC@o‐rGO exhibited a high specific capacity 233.4 mAh g−1 after 1500 cycles at 2.0 A g−1. Coupled with activated carbon, a potassium‐ion hybrid capacitor displayed a high energy density of 176.6 Wh kg−1 at 1800 W kg−1 and a superior capacity retention of 82.51% at 2.0 A g−1 after 11000 cycles.
Effect of organic Na+‐montmorillonite on the dielectric and energy storage properties of polypropylene nanocomposites with polypropylene‐graft‐maleic anhydride as compatibilizer
Authors: Hu Jing , Zhao Xuanchen , Xie Junhao , Liu Yan , Sun Shulin
Published: December 2021

Polymer‐based dielectrics with excellent energy storage properties are highly desirable as electrical energy storage materials for advanced electronics and electrical power. However, the most maturely commercial film capacitor, biaxially oriented polypropylene (PP), is limited to a wider range of applications due to its low energy storage density. Herein, a one‐step melt blending method was utilized to prepare PP‐based nanocomposites to improve the energy storage performance of PP. Polypropylene‐graft‐maleic anhydride (PP‐g‐MAH) was used as a polar compatibilizer to promote the uniform dispersion of organic Na+‐montmorillonite (org‐MMT) in the PP matrix. Furthermore, the introduction of PP‐g‐MAH improved the dielectric constant of PP nanocomposites and increased charge traps. The org‐MMT enhanced the crystallinity and reduced the crystal size of PP. On the other hand, the layered structure of org‐MMT inhibited electric tree branching and growth. The PP‐based nanocomposites possess a relatively high dielectric constant of 3.35 and an extremely low dielectric loss of 0.0012 at 1000 Hz. The PP/PP‐g‐MAH/org‐MMT nanocomposite with an optimized org‐MMT content (0.2 wt%) exhibited a discharged energy density of 5.2 J/cm3at the electric field of 500 MV/m with a superior charge–discharge efficiency of 93.5%, which were favorable for its application as film capacitor materials.

Doubly robust weighted composite quantile regression based on SCAD‐L2
Authors: Cao Zhimiao , Kang Xiaoning , Wang Mingqiu
Published: December 2021

In this article, a robust variable selection procedure based on the weighted composite quantile regression (WCQR) is proposed. Compared with the composite quantile regression (CQR), WCQR is robust to heavy‐tailed errors and outliers in the explanatory variables. For the choice of the weights in the WCQR, we employ a weighting scheme based on the principal component method. To select variables with grouping effect, we consider WCQR with SCAD‐L2penalization. Furthermore, under some suitable assumptions, the theoretical properties, including the consistency and oracle property of the estimator, are established with a diverging number of parameters. In addition, we study the numerical performance of the proposed method in the case of ultrahigh‐dimensional data. Simulation studies and real examples are provided to demonstrate the superiority of our method over the CQR method when there are outliers in the explanatory variables and/or the random error is from a heavy‐tailed distribution.

Legal considerations of remote teaching as an ADA accommodation
Authors: Cheng An Chih
Published: December 2021

On Sept. 7, 2021, the Equal Employment Opportunity Commission filed a lawsuit against ISS Facility Services, Inc., headquartered in San Antonio, alleging the firm violated the American with Disabilities Act of 1990 by denying an employee's request for remote work as an accommodation, and by later firing her for her request (Civil Action No. 1:21‐CV‐3708‐SCJ‐RDC). The ISS employee has a pulmonary illness that makes it difficult for her to breathe and places her at high risk from developing severe illness from COVID‐19. This lawsuit is the first of its kind that the EEOC brought for denied accommodation related to COVID‐19. The EEOC argues that a medical condition making an employee “high risk” qualifies for ADA disability, that remote work is a reasonable accommodation, and that on‐site attendance is not always an essential function.

Edaphic heterogeneity and the evolutionary trajectory of Amazonian plant communities
Authors: Lehtonen Samuli , Muscarella Robert , Moulatlet Gabriel , Balslev Henrik , Tuomisto Hanna
Published: December 2021

We investigated how the phylogenetic structure of Amazonian plant communities varies along an edaphic gradient within the non‐inundated forests. Forty localities were sampled on three terrain types representing two kinds of soil: clayey soils of a high base cation concentration derived from the Solimões formation, and loamy soils with lower base cation concentration derived from the Içá formation and alluvial terraces. Phylogenetic community metrics were calculated for each locality for ferns and palms both with ferns as one group and for each of three fern clades with a crown group age comparable to that of palms. Palm and fern communities showed significant and contrasting phylogenetic signals along the soil gradient. Fern species richness increased but standard effect size of mean pairwise distance (SES.MPD) and variation of pairwise distances (VPD) decreased with increasing soil base cation concentration. In contrast, palm communities were more species rich on less cation‐rich soils and their SES.MPD increased with soil base cation concentration. Species turnover between the communities reflected the soil gradient slightly better when based on species occurrences than when phylogenetic distances between the species were considered. Each of the three fern subclades behaved differently from each other and from the entire fern clade. The fern clade whose phylogenetic patterns were most similar to those of palms also resembled palms in being most species‐rich on cation‐poor soils. The phylogenetic structuring of local plant communities varies along a soil base cation concentration gradient within non‐inundated Amazonian rain forests. Lineages can show either similar or different phylogenetic community structure patterns and evolutionary trajectories, and we suggest this to be linked to their environmental adaptations. Consequently, geological heterogeneity can be expected to translate into a potentially highly diverse set of evolutionarily distinct community assembly pathways in Amazonia and elsewhere.

Published: December 2021

Graphite is the dominant anode material for lithium‐ion batteries; however, it still suffers from Li‐plating when charging fast or at low temperature, and Li‐plating is associated with performance fading and safety concerns. Herein, we clarify the mechanism of lithium evolution from graphite particles by over‐lithiation cycle test, in‐situ XRD, and titration gas chromatography. We observe that the graphite intercalation compounds (GICs, LiC12 and LiC6 e.g.) gradually become inactive and wrapped by dead lithium or side reaction sediments, while the rate of this degradation will be accelerated as the overpotential of Li‐plating is decreased after initial Li metal nucleation. This understanding is contradictory to the popular one that the degradation of graphite anode after Li plating is mainly caused by the inferior SEI and dead Li induced hindering of Li‐ion intercalation. The isolation of lithiated graphite particles leading to the fast vanishing of Li insertion/deintercalation process in graphite anodes. We further study the insertion/deintercalation vanishing process at low temperature and high rates, respectively. This work provides a insight on graphite anode degradation induced by Li‐plating, and the new understanding can be used to guide the design of advanced materials and electrodes to avoid Li‐plating and achieve extreme fast while safe charging.
A minimal resource high‐speed routing lookup mechanism for servers with NetFPGAs

Published: December 2021

This paper studies how high‐performance computer servers, equipped with Field‐Programmable Gate Arrays (FPGAs), can perform high‐speed routing. In particular, routing table lookup is considered since it is a key packet processing bottleneck for future routers that need to operate at Petabits‐per‐second. The paper defines and evaluates three routing lookup schemes used by routers/switches, using Xilinx NetFPGA SUME programmable data plane hardware boards. Two existing schemes, namely IP address‐based Longest Prefix Matching and Multi‐Protocol Label Switching tag‐based exact matching are implemented. In addition, the paper presents a new routing scheme called No Lookup Forwarding Scheme (NLFS) that does not use conventional lookup tables. The NLFS approach adds a custom routing tag that does not require any form of (forwarding) table lookup, and independent of the Binary/Ternary Content Associate Memory (CAM) capacity in the switch/router. The experimental results show that the NLFS scheme utilizes less FPGA resources, while reducing packet lookup latency by up to 18% against longest prefix match which is the de facto lookup mechanism used in switches. The key contribution of this work is that it enables the use of NetFPGAs to reduce CAM capacity requirements in switches/routers to help reduce memory costs. The proposed scheme has several use cases, including provision of on‐demand increase of packet routing capacity in data center networks and support for Network Function Virtualization‐based systems.

Primary mitochondrial diseases (PMD) are genetic disorders with extensive clinical and molecular heterogeneity where therapeutic development efforts have faced multiple challenges. Clinical trial design, outcome measure selection, lack of reliable biomarkers, and deficiencies in long‐term natural history data sets remain substantial challenges in the increasingly active PMD therapeutic development space. Developing “FAIR” (findable, accessible, interoperable, reusable) data standards to make data sharable and building a more transparent community data sharing paradigm to access clinical research metadata are the first steps to address these challenges. This collaborative community effort describes the current landscape of PMD clinical research data resources available for sharing, obstacles, and opportunities, including ways to incentivize and encourage data sharing among diverse stakeholders. This work highlights the importance of, and challenges to, developing a unified system that enables clinical research structured data sharing and supports harmonized data deposition standards across clinical consortia and research groups. The goal of these efforts is to improve the efficiency and effectiveness of drug development and improve understanding of the natural history of PMD. This initiative aims to maximize the benefit for PMD patients, research, industry, and other stakeholders while acknowledging challenges related to differing needs and international policies on data privacy, security, management, and oversight.

Objective

To examine severe birth‐related injuries in neonates among mothers with different types of diabetes.

Methods

Retrospective cohort study based on Finnish Medical Birth Register data from 2004 to 2017. The study included singleton neonates born vaginally with cephalic presentation (n = 623 649) after 35+0 weeks of gestation. The primary outcome variable was severe birth injury. Incidences, crude and adjusted odds ratios, and probabilities in regression analysis were calculated for different types of diabetes.

Results

There were 1952/623 649 (0.3%) severe birth injuries of which brachial plexus injury occurred most frequently. The injury incidence was highest in neonates of women with type 1 or type 2 diabetes, 42/1659 (2.5%) and 10/548 (1.8%), respectively. For gestational diabetes, the injury incidence was comparable to non‐diabetic women: 422/77 810 (0.5%) and 1478/543 632 (0.3%), respectively. Shoulder dystocia, high birthweight, and vacuum‐assisted delivery were associated with the highest probability for injury. Birthweight and obesity had a stronger impact on injury risk in women with pregestational diabetes compared to other pregnancies.

Conclusion

Neonates of women with pregestational diabetes have a higher risk for severe birth injury than other neonates. The injury risk in neonates delivered by women with gestational diabetes or non‐diabetic women is generally low.

Multiple ‘overviews of reviews’ conducted on the same topic (“overlapping overviews”) represent a waste of research resources and can confuse clinicians making decisions amongst competing treatments. We aimed to assess the frequency and characteristics of overlapping overviews. MEDLINE, Epistemonikos and Cochrane Database of Systematic Reviews were searched for overviews that: synthesized reviews of health interventions and conducted systematic searches. Overlap was defined as: duplication of PICO eligibility criteria, and not reported as an update nor a replication. We categorized overview topics according to 22 WHO ICD‐10 medical classifications, overviews as broad or narrow in scope, and overlap as identical, nearly identical, partial, or subsumed. Subsummation was defined as when broad overviews subsumed the populations, interventions and at least one outcome of another overview. Of 541 overviews included, 169 (31%) overlapped across similar PICO, fell within 13 WHO ICD‐10 medical classifications, and 62 topics. 148/169 (88%) overlapping overviews were broad in scope. Fifteen overviews were classified as having nearly identical overlap (9%); 123 partial overlap (73%), and 31 subsumed (18%) others. One third of overviews overlapped in content and a majority covered broad topic areas. A multiplicity of overviews on the same topic adds to the ongoing waste of research resources, time, and effort across medical disciplines. Authors of overviews can use this study and the sample of overviews to identify gaps in the evidence for future analysis, and topics that are already studied, which do not need to be duplicated.

Objectives

To investigate ultrasound (US) femoroacetabular translation measurements in female athlete patients.

Methods

A prospective cross‐sectional study was conducted in female athlete patients <50 years. Demographic data, Beighton score/hypermobility status, and sport participation were collected. Hip dysplasia was determined using radiographic measurements (lateral center edge angle, anterior center edge angle, Tönnis angle); femoral version angles were measured with CT or MR. Femoroacetabular translation US measures included neutral (N), neutral flexed (NF), extension external rotation/apprehension (EER) positions. Maximal difference (delta) between US measures was calculated.

Results

206/349 female hips were analyzed (median age 21.2 years [range, 12–49.5]). The primary sport group was performing arts (45%, 92/206). Mean Beighton score was 5.2 (SD, 2.5) with 61% (129/206) of hips exhibiting hypermobility (Beighton score ≥5). For each additional unit of Beighton score, N US measurement increased by 0.7 mm (β = 0.7; 95% confidence interval [CI] = 0.22–1.25; P < .001), NF by 1 mm ( = 0.9; 95% CI = 0.3–1.43; P = .002) and EER by 0.8 mm ( = 0.8; 95% CI = 0.27–1.37; P < .001) when adjusting for age and dysplasia status. A positive correlation was detected between NF (r = 0.19; 95% CI = 0.05–0.33; P = .007) and EER (r = 0.19; 95% CI = 0.05–0.32; P = .01) with Tönnis angle and a negative correlation between the delta and femoral version (r = −0.20; 95% CI = −0.35 to 0.03; P = .02). No difference in US measures was detected across sport groups (N [P = .24], NF [P = .51], EER [P = .20], delta [P = .07]).

Conclusion

Beighton score was independently associated with dynamic US measures in female athlete patients who are not hypermobile when controlling for other factors.

Investigating the origins of goose domestication relies on successful identification of this species and, specifically, distinguishing it from its wild, morphologically similar, form. Here we present the first attempt to separate wild and domestic geese recovered from Estonian archaeological assemblages using a combination of morphometrics and stable isotope analysis. To this aim, measurements from 159 archaeological bones were compared with modern specimens. Twenty‐five archaeological samples were chosen for stable isotope analysis based on their morphometrics. The results of this paper show that bones identified as “domestic” by their size and shape had significantly higher δ15N values compared with those identified as “wild.” The higher δ15N could be a result of dietary differences, for example, the role of manured crops and/or animal protein in the diets of domestic geese.

Published: December 2021

This article proposes and demonstrates a new classification system of fish population level effects of hydropeaking operations in rivers. The classification of impacts is developed along two axes; first, the hydromorphological effect axis assesses the ecohydraulic alterations in rivers introduced by rapid and frequent variations in flow and water level, second the vulnerability axis assesses the site‐specific vulnerability of the fish population. Finally, the population level impact is classified into four classes from small to very large by combining the two axes. The system was tested in four rivers in Norway exposed to hydropeaking, and they displayed a range of outcomes from small to very large impacts on the salmon populations. The river with a relatively high base flow and ramping restrictions scored better than rivers with the lower base flow or limited ramping restrictions, indicating that hydropeaking effects can be mitigated while maintaining high hydropower flexibility. Most effect factors could easily be calculated from timeseries of discharge and water level, whereas the use of hydraulic models to estimate potential stranding areas may require more work. The vulnerability factors are mainly qualitative and depend more heavily on expert judgments and are thus more uncertain. The system was deemed suitable for the purpose of supporting management decisions for rivers exposed to hydropeaking operations. It evaluates the severity of the additional pressures due to hydropeaking operations and proved useful to identify mitigating measures. While the system was developed for Atlantic salmon river systems, it could be adapted to other species or systems.
