Buckling of cellular members loaded by an axial force

Cellular members are steel I-section members with large round web openings. Because of these openings, the material use of these members loaded in bending in more economical than for classical plain-webbed I-section members. These members are also used for applications in which they are loaded by an axial compressive force and a relatively large bending moment. However, the behaviour of cellular members in these loading conditions is still unknown, and must be investigated. As a part of this more extensive research, the authors have studied numerically the general elastic buckling behaviour of cellular members loaded by an axial force. In this paper, the results of this study are presented and compared with a proposed analytical expression for the flexural buckling load. It is found that this expression is accurate for the examined cellular members, the failure behaviour in compression of cellular members being very similar to that of plain-webbed members.
“Thank you, Marojejy:” affective learning outcomes of student participants in place-based field trips to Marojejy National Park

Evaluations of conservation education programmes are most often concerned within the cognitive domain, where logical learning takes place. In place-based education, emphasis is instead placed on learning in multiple domains, including the cognitive and affective domains. Here, we quantitatively and qualitatively evaluate student learning in the affective domain following a series of short educational trips to Marojejy National Park, Northeast Madagascar. Student responses to the prompt “write about your trip to Marojejy” were evaluated for content, including emotional responses using cultural consensus, saliency scoring, and qualitative evaluation. The most salient term used in responses were “a good trip”. when tested 1.5 to 2 weeks after their trip. Students wrote about the emotional impact of the trip in four out of five levels of the affective domain. Our findings highlight the value of place-based education for learning in the affective domain. We demonstrated that even over a brief period of three days, placebased conservation education can have a marked impact on the values and emotions of participants. Les évaluations de programmes d’éducation en matière de préservation sont le plus souvent axées sur le domaine cognitif, là où s’effectue l’apprentissage logique. Dans l’éducation effectuée sur place, l’accent est au contraire mis sur un apprentissage multidisciplinaire, qui inclut à la fois les domaines cognitifs et affectifs. Ici, nous évaluons de façon quantitative et qualitative l’apprentissage des étudiants dans le domaine affectif en suivant une série de brèves excursions à but éducatif au Parc national de Marojejy, dans le Nord-Est de Madagascar. Les réponses des étudiants à l’instruction « Parlez-nous de votre excursion à Marojejy » ont fait l’objet d’une évaluation tenant également compte des aspects émotionnels, sur la base du consensus culturel, du score de saillance et du point de vue qualitatif. L’expression la plus saillante utilisée dans les réponses a été « bonne excursion » dans les tests effectués 1,5 à 2 semaines après leur retour. Les étudiants ont relaté l’impact émotionnel de l’excursion dans quatre des cinq niveaux du domaine affectif. Nos résultats mettent en évidence la valeur d’une éducation sur place pour un apprentissage au niveau affectif. Nous avons démontré que même après une brève période de trois jours, l’éducation en matière de préservation peut avoir, lorsqu’elle est effectuée sur place, un impact significatif sur les valeurs et les émotions des participants.
Is brand experience a good mediator? An empirical study on ISP sector

Notwithstanding the increasing acknowledgment of prominence of Brand Loyalty (BL), in business performance, research efforts directed at investigating the relationship among Brand Service Quality (ServQ), Brand Experience (BE), Brand Trust (BT) and Brand Loyalty (BL) in the context of Kurdistan Region internet service industry, have largely been neglected. Therefore, the principal objective of this study is to fill this void. Service quality in this research is measured in two dimensions: technical and functional, while BE is measured in four dimensions: sensory, affective, intellectual, and behavioral. In particular, the current study seeks to explore the direct effects of Technical Service Quality (TQ) and Functional Service Quality (FQ) on consumer BE, BT and BL; and the mediating role of BE in brand service quality – brand trust relationship. Moreover, the direct impact of BT on BL along with the mediating role of BT in the BE-BL relationship will also be examined. To empirically test the posited research hypotheses, data is collected from internet consumers in Sulaymaniyah and Erbil provinces of the Kurdistan region in Iraq. In total, 485 internet users were interviewed in the region. The collected data were analyzed using IBM AMOS 23. Findings demonstrate that the Technical Quality of internet services impacts Brand Experience more positively than Functional Quality does. On the contrary, Functional Quality affects the customer Brand Trust directly while Technical Quality does not have any direct impact on the customer Brand Trust. Secondly, It is also observed that Brand Experience significantly mediates the relations between Technical Quality and Brand Trust. The direct impact of the Functional Quality on Brand Trust was stronger than the mediation effect of Brand Experience between Functional Quality and Brand Trust. It was observed that Brand Trust had a significant impact on customer Brand Loyalty. Lastly, Brand Trust significantly mediates the relations between Brand Experience and Brand Loyalty.
An experimental study on magnetic field-assisted-EDM process for Inconel-625

ABSTRACT In this experimental study, the effect of magnetic field on electrical discharge machining (EDM) performance was evaluated for Inconel-625. The magnetic-field-assisted EDM (MFA-EDM) process is defined as a combination of EDM and magnetic field environment. Permanent magnets were installed at the proper distance for the creation of a magnetic field and the experiments were conducted using the Cu tool. Magnetic field intensities of 0.396 T and 0.665 T were applied during EDM operations. Performance of the EDM under the action of different magnetic fields was evaluated based on material removal rate (MRR), tool wear rate (TWR), and average surface roughness (Ra). The experimental results showed that higher MRR, higher TWR, and lower Ra values were observed under the action of the magnetic field. The scanning electron microscope (SEM) analysis also confirmed a better surface quality under the action of the magnetic field. The SEM micrograph showed the presence of lesser cracks present on the machined surface with MFA-EDM.
Satellite Tracking of Migration Routes of the Eastern Buzzard (Buteo japonicus) in Japan through Sakhalin

We satellite-tracked the eastern buzzard (Buteo japonicus) wintering in Japan to delineate both northward and southward migration routes, destinations, and stopover behavior. Twenty-two buzzards were captured and fitted with functional platform transmitter terminals. For these buzzards that departed from the capture sites, we observed a total of 65 northward migrations during 2008–2016 and a total of 55 southward migrations during 2008–2015. In spring, the eastern buzzards migrated eastward along the Seto Inland Sea in the Chugoku region or further inland. In eastern Honshu, they followed two different routes. One was to Hokkaido via the Tsugaru Peninsula from central or northern central Honshu northward along the side of the Sea of Japan in northern Honshu. The other was to Hokkaido via the Shimokita Peninsula, mainly from the Pacific Ocean side of northern Honshu, moving eastward through central Honshu. Of the 17 birds tracked, 10 summered in Sakhalin, three in Hokkaido, three in northern Honshu, and one unknown. In autumn, the buzzards retraced their northward migration routes. Of the 14 birds that were tracked the entire southward migration, 13 (92%) returned to their respective capture sites. One juvenile wintered in an area different from the capture site. Our study contributes to a deeper understanding of the distribution of breeding and wintering grounds and the migration routes of B. japonicus. In addition, the information on migration obtained in this study can contribute toward appropriate environmental impact assessment for wind power facilities in Japan.
Osteochondral Lesions of the Ankle Treated with Bone Marrow Concentrate with Hyaluronan and Fibrin: A Single-Centre Study

Osteochondral defects of the ankle (OCD) are being increasingly identified as a clinically significant consequence of injury to the ankle, with the potential to lead to osteoarthritis if left untreated. The aim of this retrospective cohort study was to evaluate a single-stage treatment of OCD, based on bone marrow aspirate (BMA) centrifuged to produce bone marrow concentrate (BMC). In a dual syringe, the concentrate was mixed with thrombin in one syringe, whereas hyaluronan and fibrinogen were mixed in a second syringe. The two mixtures were then injected and combined into the prepared defect. Clinical outcome and quality of life scores (MOXFQ and EQ-5D) were collected at baseline and yearly thereafter. Multilevel models were used to analyse the pattern of scores over time. Ninety-four patients were treated between 2015 and 2020. The means of each of the three components of the MOXFQ significantly improved between baseline and 1 year (p < 0.001 for each component), with no further change from year 1 to year 3. The EQ-5D index also improved significantly from baseline to 1 year, with no evidence for further change. Our results strongly indicate that this BMC treatment is safe for, and well tolerated by, patients with OCD of the ankle as both primary treatment and those who have failed primary treatment. This technique provides a safe, efficacious alternative to currently employed cartilage repair techniques, with favourable outcomes and a low complication rate at 36 months.
Proximal Femur Responses to Sequential Therapy With Abaloparatide Followed by Alendronate in Postmenopausal Women With Osteoporosis by 3D Modeling of Hip Dual‐Energy X‐Ray Absorptiometry (DXA)

Previous subgroup analyses from the ACTIVE trial in women with postmenopausal osteoporosis (NCT01343004) using three‐dimensional (3D)‐processing of dual X‐ray absorptiometry (DXA) scans indicated greater increases in total hip cortical volumetric bone mineral density (Ct.vBMD) and estimated indices of hip strength following 18 months of abaloparatide (ABL) versus placebo or teriparatide. The current post hoc analyses describe hip 3D‐DXA data for ACTIVExtend (NCT01657162), in which 18 months of ABL followed by 24 months of alendronate (ABL/ALN) increased hip and spine areal BMD (aBMD) and reduced fracture risk versus placebo (PBO) followed by ALN (PBO/ALN). In an ACTIVExtend subgroup (ABL/ALN, n = 204; PBO/ALN, n = 202), hip DXA scans retrospectively underwent 3D modeling via 3D‐Shaper software. Changes from baseline in cortical and trabecular compartments were calculated for total hip and hip subregions (femoral neck, trochanter, and shaft). Estimated strength indices comprising cross‐sectional moment of inertia, section modulus, and buckling ratio were calculated for each hip subregion. Correlations between bone turnover marker levels at the time of alendronate initiation and subsequent BMD gains with alendronate were also investigated within each group. Total hip trabecular and cortical 3D‐DXA parameters increased from baseline in both groups (all p < 0.001), with greater average increases for ABL/ALN versus PBO/ALN (trabecular vBMD: 10.87% versus 4.3%; cortical thickness: 2.32% versus 1.14%; Ct.vBMD: 3.41% versus 1.86%; cortical surface BMD: 5.82% versus 3.0%; all p < 0.001). Strength indices in the ABL/ALN group improved in all subregions versus baseline (all p < 0.0001) and versus PBO/ALN (all p < 0.02). In the ABL/ALN group, collagen type I N‐terminal propeptide (P1NP) levels at the time of alendronate initiation correlated with subsequent percent changes in all 3D‐DXA parameters with 24 months of alendronate therapy. In conclusion, sequential ABL/ALN or PBO/ALN treatment improves trabecular and cortical 3D‐DXA parameters at the hip, as well as strength indices of hip subregions, with greater increases with ABL/ALN versus PBO/ALN. © 2022 Radius Health, Inc.

Associations between Exercise-Induced Pulmonary Hemorrhage (EIPH) and Fitness Parameters Measured by Incremental Treadmill Test in Standardbred Racehorses

Simple Summary Exercise-induced pulmonary hemorrhage (EIPH) frequently affects racehorses worldwide and has been widely associated with poor performance; however, scientific evidence supporting this observation is low. The present retrospective study aims to evaluate objectively whether the presence and grade of EIPH could affect some fitness parameters, measured during an incremental treadmill test, in poorly performing Standardbred racehorses. For this purpose, the association between EIPH and the results of a treadmill metabolic test (including blood lactate analysis and venous blood gas analysis) were evaluated in 81 Standardbred racehorses. No relationship between EIPH and aerobic/anaerobic capacity was observed, suggesting that EIPH may affect performance in a different manner. However, EIPH-affected horses were shown to reach higher hematocrit values during exercise compared to EIPH-negative horses; therefore, it may be hypothesized that hemoconcentration may take part in the pathogenesis of EIPH by increasing the pulmonary capillary pressure. Abstract Exercise-induced pulmonary hemorrhage (EIPH) is a condition affecting up to 95% of racehorses, diagnosed by detecting blood in the trachea after exercise and/or the presence of hemosiderophages in the bronchoalveolar lavage fluid (BALf). Although EIPH is commonly associated with poor performance, scientific evidence is scarce. The athletic capacity of racehorses can be quantified through some parameters obtained during an incremental treadmill test; in particular, the speed at a heart rate of 200 bpm (V200), and the speed (VLa4) and the heart rate (HRLa4) at which the blood lactate concentration reaches 4 mmol/L are considered good fitness indicators. The present retrospective study aims to evaluate whether EIPH could influence fitness parameters in poorly performing Standardbreds. For this purpose, data from 81 patients regarding their V200, VLa4, HRLa4, peak lactate, maximum speed, minimum pH, and maximum hematocrit were reviewed; EIPH scores were assigned based on tracheobronchoscopy and BALf cytology. The association between the fitness parameters and EIPH was evaluated through Spearman’s correlation analysis. No relationship between EIPH and V200, VLa4, and HRLa4 was observed. Interestingly, EIPH-positive horses showed higher hematocrit values (p = 0.0072, r = 0.47), suggesting the possible influence of the hemoconcentration on the increase of pulmonary capillary pressure as a part of the pathogenesis of EIPH.
The reasons of Iranian football clubs failure in the Asian football champions' league.

The purpose of this research was to study the reasons of Iranian football clubs failure in the Asian football champions’ league. The research was descriptive and its population included managers and coaches that were familiar with football. A research-made questionnaire was used to collect data; its content and face validity was confirmed by 10 sport management and football experts and tool reliability was confirmed by Cronbach's alpha (α=0.84). The information of 105 distributed questionnaires was analyzed by Friedman test. The results showed that among 5 components (management and organizing, coach and technical staff, the external components, players, economic and financial), the management and organizing component have the greatest roles in the success of football clubs. It is suggested that aware and experienced managers and coaches in sports, spend most of their attention for grassroots football and setting long-term plan for teams.
A Highly Divergent Hepacivirus Identified in Domestic Ducks Further Reveals the Genetic Diversity of Hepaciviruses

Hepaciviruses represent a group of viruses that pose a significant threat to the health of humans and animals. During the last decade, new members of the genus Hepacivirus have been identified in various host species worldwide, indicating the widespread distribution of genetically diversified hepaciviruses among animals. By applying unbiased high-throughput sequencing, a novel hepacivirus, provisionally designated Hepacivirus Q, was discovered in duck liver samples collected in Guangdong province of China. Genetic analysis revealed that the complete polyprotein of Hepacivirus Q shares 23.9–46.6% amino acid identity with other representatives of the genus Hepacivirus. Considering the species demarcation criteria for hepaciviruses, Hepacivirus Q should be regarded as a novel hepacivirus species of the genus Hepacivirus within the family Flaviviridae. Phylogenetic analyses also indicate the large genetic distance between Hepacivirus Q and other known hepaciviruses. Molecular detection of this novel hepacivirus showed an overall prevalence of 15.9% in duck populations in partial areas of Guangdong province. These results expand knowledge about the genetic diversity and evolution of hepaciviruses and indicate that genetically divergent hepaciviruses are circulating in duck populations in China.
Short Communication Effect of Planting Density on the Performance of Hybrid Rice (Oryza sativa L.) under Waterlogged Condition

The experiment was conducted to find out the effect of planting density on the performance of hybrid rice variety Aloran under water logged condition at the BRAC Agricultural Research and Development Center in Gazipur, Bangladesh during the dry (DS) and wet season (WS) of 2009. Different planting densities were maintained using different spacings and number of seedlings per hill. These include 25 cm × 20 cm, 25 cm × 10 cm, 20 cm × 10 cm, 20 cm × 15 cm with single seedling per hill and 20 cm × 15 cm with two seedlings per hill and 20 cm × 15 cm with three seedlings per hill. The experiment was laid out in a randomized complete block design with 3 replications. Density of 20 cm × 10 cm with 1 seedling hill -1 i.e. 50 hills m -2 produced the highest grain yield of 7.5 t ha -1 and 4.6 t ha -1 in DS and WS respectively, which was significantly higher than the yield with recommended density (20 cm × 15 cm with 1 seedling per hill). This yield was increased due to higher number of panicles m -2 . Increasing the seedling numbers hill -1 with the recommended planting density did not improve the yield of hybrid rice. This result suggests that higher planting density rather than increased number of seedling hill -1 is necessary for getting higher yield of hybrid rice in continuous water logged condition.
Efficacy of a Virtual Fracture Clinic Model Created During Covid-19 Pandemic

Background: At the start of the COVID-19 pandemic we introduced a Virtual Fracture Clinic (VFC) in our orthopaedic department in which clinical records and imaging were reviewed by an orthopaedic consultant and physiotherapist / nurse without the patient being physically present. All patients received a copy of the clinic note outlining an agreed management plan. VFC’s have been successfully trailed in other orthopaedic departments, however, no study has reported on the process of setting up a VFC during a pandemic, nor the frequency and types of injuries seen in the clinic.
Effective Digital Marketing Strategies Used by MSMEs in NCR Under New Normal

The changes in our daily lives, or, which have been called the "new normal," have an implication in the shifting of tradition to online business activities. This study aims to explore how effective search engine marketing, content marketing, influential marketing, social media marketing, and email marketing as strategies in digital marketing used by different MSMEs operating in NCR under the new normal and if these strategies can give a long-term gain in businesses. The study was conducted through a survey questionnaire by MSMEs owners in NCR. The study results found that Social Media Marketing is very effective as a Digital Marketing strategy and has a significantly low positive relationship with Digital Content and Influencer Marketing. The study will contribute to identifying the effectiveness of digital marketing strategies that will benefit the businesses under the new normal in terms of increasing their sales and in the future, as people get accustomed to the activities under the new normal.
Language Assessment Literacy of Middle School English Teachers in Mexico

Because English is an integral component of education in Mexico, it is necessary to explore teachers’ language assessment literacy (LAL), or their language assessment knowledge and practices. Previous LAL studies have been performed in standardized testing-focused. However, the present study aims to explore the LAL of teachers of middle school English students in a context where governmental policies strive to engender communicative language learning, specifically, Mexico. I have taken a mixed methods approach which involved a survey (N = 123) and interviews at two locations in Mexico. The semi-structured interviews were conducted at one bilingual middle school (N = 7) and in one extracurricular English program (N = 6). Participants were asked about their previous training, confidence levels in their assessment practices, and their training needs. Findings suggest a divide among teachers with higher and lower levels of LAL. Participants indicated that their training primarily covered traditional forms of assessment and classroom-level decision-making. However, data also suggest that participants valued non-traditional assessment activities. Finally, participants desired training on topics such as the use of technology in assessment, unfamiliar non-traditional assessment activities, and program-level decision-making.
