The object of this study is the process of grinding and crumbling the surface layer of the soil with turf of winter crops by X-shaped working bodies. It has been established that the use of a grinding group based on X-shaped rotary working bodies as part of combined tillage tools makes it possible to preliminary loosen the surface layer of heavy soils (overdried or overmoistened). It was established that the optimal values of the parameters of the section of the X-shaped rotary working bodies for the quality of loosening the soil in a layer of 0–10 cm at a depth of cultivation of 14±2 cm depend on the speed of the unit. Thus, at a speed of movement of the unit of 2 m/s, the optimal value of the diameter of the rotor blade is 335.9 mm, the distance between the axes of the rotor batteries is 316.4 mm, and the distance between the rotor blades in the battery is 195.6 mm. At a unit movement speed of 2.5 m/s, the optimal values of these parameters are 331.2, 325.7, and 211.3 mm, respectively, and at a unit movement speed of 3 m/s – 330.1, 346.8, and 106.1 mm. It was also established that the stability of the movement of the X-shaped working bodies according to the root mean square deviation of the working depth increases with the increase in the speed of the unit. Thus, at a unit movement speed of 2.5 m/s, the root mean square deviation of the soil tillage depth is 1.21 cm, at a unit movement speed of 3 m/s – 1.07 cm, and at a unit movement speed of 3.5 m/s – 0 .63 cm. It was also established that the stability of the movement of the working bodies according to the depth of cultivation decreases with an increase in the speed of movement of the unit. Thus, at a movement speed of the unit of 2.5 m/s, the average soil tillage depth is set at the level of 13.1 cm, at a movement speed of the unit of 3 m/s – 12.6 cm, and at a movement speed of the unit of 3.5 m/s – at the level of 11.9 cm.

The object of this study was the weld material of a new Ti-6.1Al-6.0Zr-6.3Sn-3.2Mo-1.1Nb-1.2Si alloy, which was obtained by electron beam welding.
Electron beam welding (EBW) provides rapid melting and cooling with crystallization under significant temperature gradients. For the pseudo α-titanium alloy, this leads to the appearance of significant residual stresses in the joint and determines the specificity of the dispersion decay of the β-phase. Residual stresses are reduced by preliminary heating, removed by heat treatment. Such processing exerts a critical influence on the formation of the structure and phase composition of the weld and the zone of thermal influence of the electron beam; it can form macro defects, undesirable phases, and structural states.
The conditions of heat treatment have been determined to bring the welded joint from complex alloyed pseudo α-titanium alloy to the required level of mechanical characteristics. The structure, phase morphology, elemental composition, and mechanical characteristics of welded joints without additional heat treatment have been compared, with preliminary local heating of 400 °C, with additional post-weld local annealing at ТТ=750 °С, tT=4 minutes and sequential annealing in the furnace at ТТ=850 °C, tT=60 minutes. It has been established that a full cycle of heat treatment of a welded joint provides the highest characteristics of strength and plasticity, but local heat treatment also makes it possible to obtain a defect-free joint with satisfactory characteristics for less responsible products. It is shown how heat treatment of pseudo α-titanium alloy makes it possible to get rid of unwanted phase formations (Zr,Ti)5Si3Al and transform them into (Zr,Ti,Nb,Mo)3SiAl.
The results are promising for use in the production of aircraft engine parts

Published: September 2024

The object of the study is epidemiological grouping using the SEIR mathematical model on a machine learning-based multilayer network. The problems in this research are related to managing epidemiological data on a large scale to determine disease patterns and identification such as the number of recovered cases, number of infected cases and number of deaths and demographic factors. In the process, traditional methods make it difficult to carry out processes such as determining patterns and identifying diseases. So, it is necessary to use machine learning and the SEIR (Susceptible-Exposed-Infectious-Recovered) mathematical model which can be integrated with multilayer networks to increase accuracy and effectiveness in identifying diseases and determining patterns. The results obtained from this research are a model that can identify and determine patterns of disease spread in large-scale epidemiological data. In its application, the SEIR mathematical model combined into a social layer and an environmental layer in a multilayer network. This research is research with a level of novelty in the application of the SEIR mathematical model to multilayer networks and machine learning so that the model formed can be used to view the distribution of epidemiological data for disease-related information. Machine learning aims to process large-scale data in minimal time resulting in clustering and identification of diseases such as flu, Covid-19 and pneumonia. This research has an accuracy of 94 % using the MAPE evaluation technique. It is hoped that the resulting model can be used in the world of health for disease mapping in certain areas as a reference for mitigating the spread of disease

Published: September 2024

Aim. To present a clinical case of osteomalacia associated with fibroblast growth factor-23-secreting tumor under the mask of ankylosing spondylitis (AS).Materials and methods. Clinical observation of a 31-year-old patient with long-time diagnosis of AS is presented. Underestimation of back pain cause at the initial stage of diseaseled to an erroneous diagnosis of AS. A thorough assessment of the anamnesis, additional examination using modern imaging methods in combination with laboratory analysis (low blood phosphorus level, hyperphosphaturia, normal value of C-reactive protein, erythrocyte sedimentation rate, negative HLA-B27), made it possible to establish the correct diagnosis of “mesenchymal phosphaturic tumor of the left foot (surgical intervention dated 11.26.2020), secondary hypophosphatemic tumor-induced osteomalacia complicated by multiple bone fractures”, to carry out timely treatment with full recovery.Results. The literature data on epidemiology, pathogenetic mechanisms, clinical manifestations and management approaches of tumor induced phosphopenic osteomalacia are presented. An algorithm for examining patients with suspected of this disease is described, taking into account the expression of somatostatin transmembrane receptors on the surface of a mesenchymal phosphaturic tumor.Conclusion. One of the rarest causes of specific back pain is osteomalacia, which can be caused by various diseases, for example, a tumor secreting FGF23 The complexity of the diagnosis lies in the non-specificity of clinical manifestations – generalized myalgia and myopathy, ossalgia, pathological fractures, etc. Timely diagnosis and radical treatment makes it possible to achieve stable remission with complete leveling of symptoms, therefore surgical excision of the tumor is the “gold” standard of therapy.

Authors: Torres-Reyes Aura M. 
Published: September 2024

As we move into late postmodernity, the instruments and processes proposed require research and development processes that allow them to remain in force within current technological mediations and trends. In this context, the instruments that facilitate vocational guidance processes are included. Therefore, this innovation experience arises as a response to the needs present in the Colombian context, based on two objectives: To reduce the number of items in the CHASIDE vocational orientation test, 2) To validate the resulting test. A longitudinal study with a quantitative approach was carried out, with a convenience sampling in three Colombian municipalities during 2019-2023. Quantitative statistical analysis techniques, data were analyzed including statistics of mean, variance, Pearson's correlation coefficient, hypothetical difference of means, degrees of freedom, t-statistic, P(t) and critical value of t (one tail and two tails), and others. Additionally, internal consistency was checked using Cronbach's Alpha. Managing to reduce the test from 98 items to 35 items, preserving its two dimensions (Aptitudes and Interests), with a simpler structure, which responds to a Multifactorial Profile (PM), its validation confirmed the new structure, that established 7 factors for the dimension of aptitudes, constituted by 27 items and 3 factors for the Interests dimension with 8 items. In conclusion, social changes are reflected in factor structures and their groupings within professions, leaving the unifactorial proposed by Holland in the RIASEC, to give way to interactions within aptitudes and interests. Aptitudes being more stable than interests over time.

Authors: GRBAVAC Vedrana , NALETILIĆ Mladenka , ŠIMIĆ Josip 
Published: September 2024

Abstract

Background: Patient education is an important aspect of physiotherapy. Effective education is based on quality communication and understanding of patients' needs. For a successful practice, it is necessary to recognize the factors that affect the ability to teach the patient and prepare new physiotherapists for this task. The research aims to determine the effect of training on the self-efficacy and skills of physiotherapy students in patient education.
Methods: Students in the final year of physiotherapy were randomized into an intervention group (52 students) and a control group (51 students). The intervention group participated in 2.5 hours of lectures, discussions, simulated exercises with colleagues, and video examples of patient education. The control group had subsequent training. All students performed a self-assessment of their teaching abilities. Patient education was assessed by a blinded evaluator using the Objective Structured Clinical Examination from an audio-recorded simulated clinical practice task.
Results: The results show no differences in demographic variables, while a significant improvement was achieved for the intervention group after the training. The intervention group before the experiment did not perform differently than the control group on self-efficacy items (p>.05), but they did perform significantly better than the control group after the experiment (p<.001). The intervention group showed better results than the control group in almost all observed fields.
Conclusion: These findings suggest that the intervention positively increased the educational skills of physiotherapy students.
Non-contact concentration measurement of aqueous ethylene glycol solutions
Authors: Iwasaki Kazuma , Fujii Sho , Tanabe Tadao 
Published: September 2024

Abstract

To evaluate the concentration dependence of THz spectra, THz time-domain spectroscopy (THz-TDS) was used to measure the transmittance of aqueous solution samples of ethylene glycol in the frequency region below 0.4 THz at room temperature, and the spectrum was analyzed in the region below 0.2 THz, where water absorption is small. The results showed that the interference spectral shape based on the dielectric constant change changed when the liquid concentration of the ethylene glycol sample was varied. Peak separation was performed for the peaks in the obtained spectra, and a comparison of the change in peak position with concentration showed a shift in the peak at 0.17 THz. This result indicates the possibility of non-contact concentration measurement using terahertz waves.

Abstract

Introduction: Current guidelines state the effectiveness of desmopressin to reduce hematoma expansion in antiplatelet-related intracerebral hemorrhage (ICH) is uncertain. This study sought to determine if desmopressin decreased hematoma expansion in ICH patients on antiplatelet agents.
Methods: We conducted a multi-center, retrospective propensity-matched cohort study at 11 US emergency departments (ED) that participate in EMPHARM-NET. Adult patients ≥18 years with a primary diagnosis of spontaneous ICH on antiplatelets prior to admission from January 1, 2017 through May 1, 2021 were included. The primary endpoint was good or excellent hemostatic efficacy within the first 24 hours following ICH between patients that did and did not receive desmopressin. Brain imaging was reviewed using 3D-Slicer by blinded expert physicians.
Results: Overall, 1408 patients were evaluated for inclusion. A total of 324 patients were included, of which 13.8% (n=45) received desmopressin and 86.1% (n=279) did not. After propensity matching, 35 patients receive desmopressin compared to 140 controls. Baseline hematoma volume (27.6 mL vs. 2.1 mL) and was significantly higher in the desmopressin group. The primary endpoint of good or excellent hemostatic efficacy was similar between groups (74.3% desmopressin group vs. 85% control group, -10.7% [-28.1% to 6.7%]). There was no difference in secondary outcomes.
Conclusion: In this multicenter cohort, patients receiving desmopressin had higher baseline intraparenchymal hematoma volume, and did not appear to result in improved hemostatic efficacy relative to the control group. These results suggest against routine administration of desmopressin for antiplatelet-related ICH, though future study in a randomized trial design is necessary.
Volumetric Dynamics of Lorica Forming Material Across the Cell Cycle in the Model Tintinnid Schmidingerella (Alveolata, Ciliophora)
Authors: Agatha Sabine , Weißenbacher Birgit , Böll Laura , Ganser Maximilian H. 
Published: September 2024

Abstract

Background
Tintinnids are marine planktonic ciliates with tube-shaped or vase-shaped loricae (shells). During cell division, lorica forming material (LFM) is generated and accumulates in the proter (anterior division product). After transverse fission, the proter leaves the lorica and secretes the material, creating its own shell, while the opisthe (posterior division product) retains the parental one. The timing of material production and its final quantity are unknown.
Results
Our study focuses on Schmidingerella Agatha & Strüder-Kypke, 2012, a model tintinnid genus with transparent, champagne flute-shaped loricae. We define five division stages based on the shapes of the opisthe’s newly forming membranellar zone (oral primordium), a feature recognisable both in live and fixed material. In monoclonal, methyl blue-eosin-stained culture material from the Northeast Pacific, the LFM is first perceptible in middle dividers and finally occupies on average 6.7% of the cell volume. The wall volume of the finished lorica estimated by a shape function is at least 4.5-fold larger than the volume of the intracellular material. Protargol-stained field material from the Chesapeake Bay at the Northwest Atlantic provides detailed morphometric data on morphostatic specimens (non-dividers) and dividers. Specimens from our culture and from the field material match in the timing of LFM production and its intracellular distribution.
Conclusions
The LFM is generated only during a certain period of the cell cycle, i.e., in early middle to late dividers. The LFM quantities in the different cell portions (anterior, middle, and posterior portion) suggest an increased production at the level of the oral primordium and the macronuclear nodules prior to its translocation into the anterior portion. The much larger volume of the finished lorica wall indicates a distinct swelling of the material after its secretion by the proter.

Published: September 2024

Abstract

The successful treatment of skin cancer and better patient outcomes depend on an early and precise diagnosis.This work offers a multiresolution assessment of the contourlet transform for the diagnosis of skin cancer, utilizing its capacity to catch fine features in images at many scales and orientations. The contourlet transform is applied to dermoscopic images to enhance feature extraction, providing a more comprehensive representation of skin lesions compared to traditional methods. The proposed method involves preprocessing dermoscopic images to improve clarity and reduce noise, followed by the application of the contourlet transform to decompose the images into various frequency bands. These decomposed images are then analyzed to extract relevant textural and structural features, which are subsequently used to train a machine learning classifier. A collection of annotated skin lesion photos is used for performance evaluation, and the outcomes are compared with state-of-the-art methods currently in use. The efficacy of the suggested method is evaluated using metrics including sensitivity, specificity, accuracy, and the area under the receiver operating characteristic (ROC) curve. The findings show that the contourlet transform-based approach performs better than traditional methods in capturing important characteristics of skin lesions, improving the ability to distinguish benign from malignant lesions and improving diagnostic accuracy. The contourlet transform is a formidable tool for the multiresolution analysis of skin cancer images, according to the study's conclusion, and it has a lot of promise for enhancing dermatology computer-aided diagnosis systems.

Abstract

Background Histologically, our understanding of intestinal polyps remains limited in scope, particularly regardingthe diverse subtypes observed in pediatric patients. To enhance our comprehension, three different polyp subtypes including solitary juvenile polyps (SJPs), juvenile polyposis syndrome (JPS)-related polyps, and Peutz‒Jegherssyndrome (PJS)-related polyps were investigated.
Methods This study usedadvanced multiplex immunohistochemistry (mIHC) technology to analyze polyps comprising 4 SJP, 4 JPS and 4 PJS polyps from 12 individual patients who underwent colonoscopies or radical surgical procedures. subtypes.
Results These mIHC analysesrevealed some differences among these polyp subtypes. PJS-related polyps, specifically, displayed epithelial dysplasia with dendritic gland hyperplasia and distinct villous structures adorned with finger-like projections on their surfaces. In contrast, SJP and JPS polyps exhibited cystic glandular dilation, with their surfaces lined with continuous but eroded epithelia. Furthermore, PJS polyps had an abundance of microvessels and thick smooth muscle fibers, whereas SJP and JPS polyps were characterized by lymphoid follicle-like structures.
Conclusions These findings not only deepen our structural understanding of various intestinal polyp subtypes but also offer valuable insights that may inform the diagnosis of patients with these conditions.
