An analysis of radiologic and anatomical parameters associated with medial osteochondral lesions of the talus in non-traumatic cases
No full textThe study aimed to provide a comprehensive analysis of radiological and anatomical measurements in patients with medial osteochondral lesions of the talus (OLT), particularly those without a history of trauma. The retrospective cross sectional study evaluated 23 medial OLT individuals aged 18–45 with no history of trauma who were identified by magnetic resonance imaging (MRI) between 2016 and 2020. The control group consisted of 27 individuals between the ages of 18 and 45 who did not have OLT and applied for other reasons. Measurements were performed with 16 parameters from anteroposterior (AP) and lateral weight-bearing ankle conventional radiographs (CR). All individuals' demographic data were assessed. A total of 50 patients aged 18–45 years, including 26 males and 24 females with a mean age of 30.28±4.46 years, were evaluated in the study. No significant differences in age or gender were found between the groups (P>0.05). Analysis of both the OLT and control groups revealed a significant association of decreased talar declination angle (P<0.001) and Meary-Tomeno's angle (P = 0.003) with medial OLT. There was no relationship between other radiological parameters and medial OLT development. In conclusion, a decreased talar declination angle and a decreased Meary-Tomeno's angle appear to have significant relationship with development of medial OLT in individuals without a history of trauma. These findings also indicate that a possible cause of medial OLT is a lower-angled positioning of the talus relative to the ground and the first metatarsus in the sagittal plane.

Study on the physical parameters of 18 contact binary stars
No full textWe present the photometric light curve solutions of 18 W Ursae Majoris-type contact binary stars with orbital periods shorter than 0.5 d. This investigation utilized photometric data from the Transiting Exoplanet Survey Satellite, Gaia, and the All Sky Automated Survey for SuperNovae. We analysed light curves using the PHysics Of Eclipsing BinariEs Python code. Eleven of the targeted systems required the inclusion of a starspot on one of the components during the analysis process. The absolute parameters of the systems were estimated using the Gaia Data Release 3 (DR3) parallax method. Based on each component's effective temperature and mass, we identified seven systems as A-subtypes and eleven as W-subtypes. We compared the results of our photometric mass ratio with a new method that estimates it using the third derivative of the light curve. The semimajor axes that were derived from the estimation of absolute parameters using the Gaia DR3 parallax method were discussed. The positions of the systems are illustrated on the logarithmic scales' mass-luminosity and mass-radius diagrams compared to the theoretical terminal-age main sequence and zero-age main sequence lines. We generated a bibliographic compilation of orbital and stellar parameters, which includes 818 contact binary systems. Then, we updated the 2D empirical parameter relationships for the primary stars, including period-temperature, period-mass, period-radius, and period-luminosity, along with diagrams illustrating the positions of the target systems. This sample is accessible as a machine-readable file for the subsequent studies

No full textÖZETMevcut deneyler, maydanoz (Petroselinum crispum) ekstraktının içme suyuna ve yerleşim sıklığına farklı yollarla katılmasının etlik piliçlerde büyüme performansı, bazı kan parametreleri ve antioksidan durumu üzerine etkilerini değerlendirmek amacıyla gerçekleştirildi. İki farklı yerleşim yoğunluğu (10 ve 15 civciv/m²) ve beş farklı katkı seviyesi (0 - katkı içermeyen kontrol grubu; 4a - her litre suya 4 ml sulu ekstrakt ilavesi; 4c - her litre suya 4 ml alkollü ekstrakt ilavesi; 8a - her litre suya 8 ml sulu ekstrakt ilavesi; 8c - her litre suya 8 ml alkollü ekstrakt ilavesi) değerlendirildi. Çalışma, 2x5 faktöriyel deney düzeneğinde (faktör 1: iki farklı yerleşim yoğunluğu; faktör 2: bes katkı seviyesi) düzenlenen ve toplam 375 adet, bir günlük, cinsiyeti belirlenmemiş Ross 308 civcivini içermekteydi. Civcivler, rastgele on farklı muamele grubuna ayrıldı ve her grup üç tekrar halinde değerlendirildi. Beş muamele grubu on civciv içerecek şekilde (yerleşim yoğunluğu: 10 civciv/m²), diğer beş grup ise on beş civciv içerecek şekilde (yerleşim yoğunluğu: 15 civciv/m²) düzenlendi. Sonuçlar, 8c tedavisinin her iki kümes yoğunluğunda da ağırlık artışı, yem verimliliği, ölüm oranları ve ekonomik indeks açısından en etkili olduğunu ve üstün fizyolojik performans sergilediğini gösterdi. Uygulamalar, heterofil (%) ve lenfosit (%) sayılarını önemli ölçüde artırdı ve en iyi yanıtlar 10 tavuk/m² yoğunluğunda gözlendi. 4c uygulaması her iki yoğunlukta da glukoz seviyelerini iyileştirirken, 4a, 4c ve 8c uygulamaları toplam protein ve kolesterol seviyelerinde üstünlük sağladı. 15 tavuk/m² yoğunluğundaki 4c ve 8a uygulamaları, daha yüksek GOT, GPT ve ürik asit seviyeleri gösterdi.Anahtar Kelimeler: Sulu ve Alkollü Ekstrakt, Maydanoz, Yoğunluk, Büyüme Performansı, Bazı Kan Parametreleri, Antioksidan DurumuABSTRACTThe present experiments wereconducted to evaluate the effects of parsley (Petroselinum crispum)extract by different ways in drinking water and stocking density on growthperformance, some blood parameters and antioxidant status of broiler chicks. Two different stocking densities (10 and 15chicks / m²) and five additive levels (0 - control treatment without additives;4a - addition of 4 millilitres of aqueous extract per litre of water; 4c -addition of 4 millilitres of alcoholic extract per litre of water; 8a -addition of 8 millilitres of aqueous extract per litre of water; 8c - additionof 8 millilitres of alcoholic extract per litre of water) were evaluated. Thestudy included 375 one-day-old unsexed Ross 308 chicks arranged in a 2x5factorial experiment (factor 1: two stocking densities; factor 2: five additivelevels). The chicks were randomly assigned to ten distinct treatment groups,each further divided into three replicates. Five treatment groups contained tenchicks each (stocking density: 10 chicks / m²), while the remaining five groupscontained fifteen chicks each (stocking density: 15 chicks / m²). The results showed that treatment 8c was themost effective in improving weight gain, feed efficiency, mortality rates, andeconomic index across both stocking densities, with superior physiologicalperformance. Treatments significantly enhanced heterophil (%) and lymphocyte(%) counts, with better responses at 10 chickens / m². Treatment 4c improvedglucose levels at both densities, while treatments 4a, 4c, and 8c showedsuperior total protein and cholesterol levels. Treatments 4c and 8a at 15chickens/m² exhibited higher GOT, GPT, and uric acid levels. Antioxidantindicators decreased in additive treatments, with better outcomes at 10chickens /m². Treatments 4c and 8c were the most effective overall.Keywords: Aqueous and AlcoholicExtract, Parsley, Stocking Density, Growth Performance,Some Blood Parameters, Antioxidant Status</p

No full textPurpose:This study aimed to examine the feasibility and effectiveness of nasopharyngoscopic velopharyngeal port assessment training given to speech-language pathology undergraduate students using a high-cost, ready-made endoscopy training model versus a low-cost, 3D-printed model.Method:A randomized comparison trial was conducted with 36 final-year undergraduate students from nine different speech-language pathology programs in Türkiye. Participants were randomly assigned to two groups and received training either with ready-made endoscopy model or the 3D-printed model. The training included theoretical and practical components, followed by self-confidence, procedural proficiency, and satisfaction assessments.Results:Both groups significantly improved in self-confidence and procedural proficiency from the pretest to posttest. There was no statistically significant difference between the two groups regarding performance, indicating that the 3D-printed model was as effective as the ready-made model. Satisfaction levels were high across both groups, with no significant differences noted.Conclusions:The low-cost, 3D-printed endoscopy training model was found to be as effective as the high-cost, ready-made model in improving students' self-confidence and proficiency in nasopharyngoscopic velopharyngeal port assessment. This finding suggests that 3D-printed models can be a viable and cost-effective alternative for simulation-based education in speech-language pathology programs, particularly in resource-limited settings.</section
Aircraft takeoff speed prediction with machine learning: parameter analysis and model development
No full textWith developing technology, the usage areas of aircraft are constantly expanded. In aircraft designed for different missions, it is an important issue to evaluate many design possibilities and make optimum designs by taking into account many parameters that are not directly connected to each other with equal importance. In this context, issues such as safety and performance come to the fore in aircraft designs. One of the critical situations affecting flight safety is the takeoff and landing phases of the aircraft. The speed changes that occur in these stages are an important issue. In this study, takeoff speed was predicted with different machine learning algorithms using takeoff speed data of the Boeing B-737-300 type aircraft. Linear regression, support vector regression, classification and regression trees, random forest regression, Extreme Gradient Boosting algorithms were selected from machine learning algorithms for takeoff speed prediction. Base models were created with these selected algorithms and the takeoff speed was predicted by training the data. Considering the obtained results, feature engineered was applied to minimise the error values of the proposed base models. In models developed by applying feature engineered, error values were reduced and better performance was observed in takeoff speed prediction. Takeoff speed values obtained with the developed models and actual flight speed values are presented comparatively for the first time in the literature. The simulation results emphasise that the developed models can be used as an effective and alternative method for takeoff speed prediction
Search for light long-lived particles decaying to displaced jets in proton-proton collisions at √s = 13.6 TeV
No full textA search for light long-lived particles (LLPs) decaying to displaced jets is presented, using a data sample of proton-proton collisions at a center-of-mass energy of 13.6 TeV, corresponding to an integrated luminosity of 34.7 fb−1, collected with the CMS detector at the CERN LHC in 2022. Novel trigger, reconstruction, and machine-learning techniques were developed for and employed in this search. After all selections, the observations are consistent with the background predictions. Limits are presented on the branching fraction of the Higgs boson to LLPs that subsequently decay to quark pairs or tau lepton pairs. An improvement by up to a factor of 10 is achieved over previous limits for models with LLP masses smaller than 60 GeV and proper decay lengths smaller than 1 m. The first constraints are placed on the fraternal twin Higgs (FTH) and folded supersymmetry (FSUSY) models, where the lower bounds on the top quark partner mass reach up to 350 GeV for the FTH model and 250 GeV for the FSUSY model
Is there a nexus between tourism development and energy transition in Asia-Pacific countries?
No full textThis paper examines the impact of tourism development on energy intensity and clean energy in 23 Asia-Pacific countries from 2000 to 2019. To ensure robust findings, both ordinary least squares (OLS) and quantile regression were applied. The findings reveal a long-term equilibrium relationship between tourism development, urbanisation, income, industrialisation, and energy transition. OLS results indicate that tourism contributes to energy efficiency while reducing clean energy use. Similarly, the quantile regression results are consistent with the OLS findings, particularly at the median and higher quantiles. These results suggest that while tourism enhances energy efficiency in Asia-Pacific countries, it limits the adoption of clean energy. To address this dual impact, policymakers should implement incentives that capitalise on tourism sector's ability to increase energy efficiency (supporting SDG-7.3), while also removing barriers to clean energy adoption (fulfilling SDG-7.2). Additionally, governments can collaborate with tourism stakeholders to develop sector-specific policies and promote environmentally responsible tourist practices
AQUEOUS AND ALCOHOLIC PARSLEY (Petroselinum crispum) EXTRACTS SUPPLEMENTED INTO DRINKING WATER AND STOCKING DENSITY AFFECT PRODUCTIVE PERFORMANCE AND ANTIOXIDANT STATUS OF BROILERS
No full textPresent experiments were conducted to evaluate the effects of aqueous and alcoholic parsley (Petroselinum crispum) extracts supplemented into drinking water and stocking density on productive performance (body weight, body weight gain, feed consumption, feed conversion ratio, mortality rate, and production and economic index) and antioxidant status (malondialdehyde, glutathione and catalase) of broilers. Two different stocking densities (10 and 15 chickens / m2 ) and 5 different additive levels (0-control treatment without additives; 4a-addition of 4 milliliters of aqueous extract per liter of water; 4c-addition of 4 milliliters of alcoholic extract per liter of water; 8a-addition of 8 milliliters of aqueous extract per liter of water; 8c-addition of 8 milliliters of alcoholic extract per liter of water) were evaluated. The study included 375 one-day old, unsexed ROSS 308 chicks, and were arranged as 2x5 factorial experiment (viz; factor 1 as two stocking densities and factor two as five additives). The chicks were randomly assigned to ten distinct treatment groups. Each treatment group was further divided into three replicates. Five treatment groups comprised ten chicks each (stocking density 10), while the remaining five groups contained fifteen chicks (stocking density 15). The results showed that treatment 8c was the best regarding weight gain, feed consumption, feed conversion ratio, reduced mortality rates, and production and economic index at both stocking densities. Treatment 4c also showed remarkable effectiveness but was lower than 8c for all studied traits. Based on the overall performance, treatments 4c and 8c are considered the best at a density of 10 chickens/m2 . Present additive treatments reduced blood serum malondialdehyde, glutathione and catalase levels at both stocking densities, indicating a reduction in oxidative stress. In general, the density of 10 chickens was more effective in improving antioxidant indicators as compared to the density of 15 chickens
