Published: September 2023

Many students have made wrong choices in their quest to making a career choice because they failed in making the right choice of counselling administrator. This study examined how counselling services affected the career decisions made by secondary school students in the state of Anambra. The specific aim at evaluating the effect of counselling orientation, appraisal, and follow-up services. The study adopted descriptive survey research design to examine the effect of counselling services on career choice of students in Anambra State. Multiple regression analysis (MRA) was used to test the hypothesis. There are an infinite number of educators and guidance counsellors in the population. Two hundred sixty-seven teachers and school counsellors were selected as the sample size. A questionnaire was used as the tool for data extraction. Data from a four-Likert scale were shown and analysed. The study found that career counselling services affect secondary school students' choices in Anambra. The results led to the conclusion that students in senior secondary schools can make wise career decisions with proper counselling services. The study recommended that directing students towards their areas of strength rather than choosing a career path that is unsuitable for them or that of their peers, can help the students with career decisions. Again, hiring counsellors with formal training and regular meetings between these counsellors and students to discuss issues that affect students' academic performance should also be a priority for school administrators.
Diagnostic value of PCR analysis of synovial fluid for the diagnosis of Lyme borreliosis in dogs
Authors: Panteleienko O. , Tsarenko T.
Published: September 2023

Lyme borreliosis, also known as Lyme disease, is a chronic multiorgan disease of humans and animals transmitted by ticks of the Ixodidae family and caused by a group of spirochetes Borrelia burgdorferi sensu lato. Dogs are one of the most susceptible animal species to Lyme disease. Symptoms of the disease in dogs can range from mild lameness and fever to more severe and potentially life-threatening conditions, such as kidney damage and neurological disorders. Due to the variety of clinical manifestations and the lack of a universal diagnostic approach, veterinarians often face difficulties in accurately diagnosing the disease. Therefore, improving the algorithms for diagnosing Lyme borreliosis in dogs remains an urgent issue for practical veterinary medicine. The article describes and analyzes data on two cases of dogs from Kyiv (Ukraine) that presented with musculoskeletal disorders, including lameness, swelling of the knee joints, and tenderness, which raised suspicion of Lyme borreliosis. The diagnostic tests used to confirm the diagnosis of Lyme borreliosis included clinical blood test, C-reactive protein test, cerebrospinal fluid cytology, enzyme-linked immunosorbent assay for IgM and IgG antigens to Borrelia burgdorferi sensu lato, computed tomography and PCR analysis of synovial fluid for the presence of Borrelia burgdorferi sensu lato DNA. As a result, the clinical blood test, C-reactive protein test, and cerebrospinal fluid cytology were not diagnostically important for the diagnosis of Lyme borreliosis. In both cases, serological tests for antibodies to Borrelia burgdorferi sensu lato were not positive. Computed tomography showed the development of an inflammatory process in the knee joints with the formation of osteophytes, enthesophytes, sclerosis of the articular surfaces, and an increase in the volume of synovial bursa. The final diagnosis of Lyme arthritis in both dogs was established by PCR analysis of synovial fluid from the affected joints for the presence of Borrelia burgdorferi sensu lato DNA. This study emphasizes the importance of considering Lyme borreliosis as a potential cause of musculoskeletal disorders in dogs. We also propose an expanded algorithm for the diagnosis of Lyme borreliosis in dogs with a pronounced symptom complex of Lyme arthritis using the method of PCR analysis of synovial fluid to detect the DNA of Borrelia burgdorferi sensu lato spirochetes.

Published: September 2023

The article presents the results of research on the peculiarities of the spelled yield formation and the grain quality depending on humate and plant growth regulator use in conditions of unstable moisture in the Forest Steppe of Ukraine. The purpose of the research was to identify the influence of elements of the technology of growing spelled varieties on the productivity and quality of the grain. During 2019–2022, research was conducted at the experimental field of the educational and production centre of the Bila Tserkva National Agrarian University. It was found that the studied varieties differ in the biological manifestations of the grain yield formation, namely Zorya Ukrainy had a yield of 5.66 t/ha, Europe – 5.89 t/ha, and Atterhauer Dinkel – 4.85 t/ha. And according to the years of research, the best conditions were in 2021, when the average yield was 5.95 t/ha, and the worst in 2020 was 5.07 t/ha. Better productivity of spelled grain was observed in a multi-year perspective with the application of Humate potassium GK-17 in the earing phase and again in the milk ripeness phase by combining it with the introduction of Agriflex Amino in the earing phase. Under such conditions, the productivity of the Zorya variety of Ukraine was 5.90 t/ha, the Europa variety was 6.43 t/ha, and the Atterhauer Dinkel variety was 5.17 t/ha. As for the qualitative characteristics of wheat and spelled grain, the option of using Humate potassium GK-17 in the earing phase and again in the milk ripeness phase by combining it with the application of Agriflex Amino in the earing phase was determined. Under such conditions, the nature of the grain of the Zorya variety of Ukraine was 663 g/l, in the Europa variety 680 g/l, and in the Atterhauer Dinkel variety 758 g/l, the protein content was 18.55 %, 18.27 %, and 14.70 % and the crude gluten content is 48.8 %, 41.6 % and 33.0 %, respectively. These values were the best in the experiment and confirmed the high efficiency of the influence of the studied factors on the quality indicators of spelled grain.

Influence of agricultural practices and sowing dates under different weather conditions on soybean yield
Authors: Syromyatnikov Y.
Published: September 2023

The article is devoted to determining the optimal sowing time for soybeans with stable warming of the soil, considers the processing with a stratifier PRSM-5 and chisel processing against the background of pre-sowing rolling. Using soil-cultivating units of three types, an analysis was made of the effectiveness of various methods of basic cultivation against the background of various agricultural practices. The optimal timing of soybean sowing was determined with stable heating of the soil to 8–10 o С when treated with a stratifier PRSM-5 and up to 10–12 o С during chisel cultivation against the background of pre-sowing rolling. The obtained results of the research showed that the soil density depends primarily on the method of basic cultivation. The analysis of soil density indicators as a whole showed that after treatment with the stratifier PRSM-5 it was somewhat less and averaged 1.04 g/cm3 , and after chisel treatment – 1.09 g/cm3 . The analysis of the structural composition of the soil showed that the best structural structure of the soil was noted when processing with a stratifier PRSM-5 due to the removal of the most agronomically valuable soil lumps from the lower layers to the surface, here the structural coefficient was high and reached 2.36, and with chisel processing – 2.08. An analysis of the reserves of productive moisture at the end of the growing season showed that during chisel processing they were used more rationally, and significantly decreased in the phase of full ripeness after processing with a stratifier PRSM-5 – they amounted to 57 mm, and after chisel processing – 69 mm. The experimental data obtained indicate that under dry weather conditions, the best yield was formed when treated with a stratifier PRSM-5 at the second sowing date, and when chisel loosening - during the first and pre-sowing rolling.

Ecological monitoring of migration of technogenic radionuclides between abiotic components and aquatic plants in the ecosystem of the Kaniv reservoir
Authors: Skyba V.
Published: September 2023

During the period of 2011–2018, the average specific activity of 90Sr in aboveground organs of prairie cordgrass, submerged club-rush, common reed, and narrow-leaved cattail ranged from 1.5 to 14.0 Bq/kg, while 137Cs ranged from 3.1 to 165 Bq/kg. Over the course of the study, a tendency towards a decrease in 137Cs accumulation levels by hydrophytes was observed. The specific activity of 137Cs in helophytes and 90Sr in helophytes and hydrophytes likely remained unchanged. In 2018, the average specific activity of 90Sr in the investigated plant species did not exceed the maximum reference values for the post-accidental period. However, the specific activity of 137Cs in prairie cordgrass exceeded the maximum reference values by 13 times, while submerged club-rush, common reed, and narrow-leaved cattail exceeded the maximum reference values by 25, 3, and 2 times, respectively. During the study period, radionuclide contamination of higher aquatic plants in the Kaniv Reservoir was predominantly formed by 137Cs, accounting for 75–90 % of the contamination. In terms of increasing specific activity of 90Sr and 137Cs, plants from different ecological groups were arranged in the following sequence: gelophytes < pleustophytes < hydrophytes, indicating a balanced radioecological state in the ecosystem of the Kaniv Reservoir. This study provides insights into the levels of radionuclide activity in aquatic plants of the Kaniv Reservoir over a seven-year period. The observed decrease in 137Cs accumulation by hydrophytes suggests a potential improvement in the environmental conditions. The findings also highlight the significant contribution of 137Cs to the overall radionuclide contamination in higher aquatic plants. The sequential distribution of plants based on increasing specific activity of 90Sr and 137Cs reflects the radioecological equilibrium within the ecosystem. This information contributes to our understanding of the environmental dynamics and radiation impact in the Kaniv Reservoir ecosystem.
Key words: 90Sr activity, 137Cs activity, radionuclides, aquatic plants, ecological monitoring, Kaniv Reservoir, radionuclide accumulation, reference values, ecosystem.

Set-Valued Stabilization of Reaction-Diffusion Model by Chemotherapy and or Radiotherapy
Authors: MOUSTAFİD Amine
Published: September 2023

This paper aims to control partial differential equations, modeling cancer chemotherapy and or radiotherapy, so in order to asymptotically stabilize the tumor density. Viability kernel of general model on set of initial condition is used to solve the control problem, and characterize the control solution as regulation law of regulation map. Three models from the literature are considered to simulate the results. The first model includes chemotherapy effect on logistic tumor proliferation, while the second one demonstrates radiotherapy effect on exponential tumor increasing, whereas the third one models the effects of the combination of chemotherapy and radiotherapy on Gompertzian tumor growth.
Changes in neuronal activity of the inferior colliculus in rat after temporal inactivation of the auditory cortex.

Published: September 2023

The role of cortico-tectal pathways in auditory signal processing was studied in anesthetized rats by comparing the extracellular single unit activity in the inferior colliculus (IC) before and after functional ablation of the auditory cortex (AC) by tetrodotoxin (TTX). The responses of several IC neurons to sound stimuli were simultaneously recorded with a 16-channel electrode probe introduced into the IC. Click-evoked middle latency responses (MLR) recorded from the AC were suppressed for several hours after TTX injection. During AC inactivation the firing rate of IC neurons increased (40 % of neurons), decreased (44 %) or did not change (16 %) in comparison with control conditions. In several IC neurons, TTX injection resulted in alterations in the shape of the rate-level functions. Response thresholds, tuning properties and the type of discharge pattern of IC neurons were not altered during AC inactivation. However, in one-third of the neurons, the initial part of the response was less altered than the later, sustained part. In two-thirds of neuronal pairs, functional decortication resulted in a change in the cross-correlation coefficient. The results reveal the complex changes that appear in IC neuronal activity after functional ablation of the ipsilateral auditory cortex.
Characterization of Magnetic Susceptor Heating Rate Due to Hysteresis Losses in Thermoplastic Welding
Authors: Martin Romain , Figueiredo Martin , Johansson Christer , Tavares Jason R. , Dubé Martine
Published: September 2023

Welding techniques are emerging as a new method to join thermoplastic composite parts. They present a fast and efficient alternative to adhesives and mechanical fasteners. Induction welding is a welding technique that relies on the application of an oscillating magnetic field on the joining interface, where a material called a magnetic susceptor generates heat by interacting with the applied magnetic field. In this work, susceptors relying on magnetic hysteresis losses made of polyetherimide (PEI) and nickel (Ni) particles are investigated with varying Ni concentration. The materials are mixed using an internal mixer and pressed to form films approximately 500μm thick. To characterize the heating rates of the susceptor materials, samples are placed on an induction coil – a water-cooled copper tube in which AC current (frequency 388kHz), generates an alternating magnetic field – and the temperature evolution is measured using a thermal camera. An increasing concentration of Ni particles results in increased heating rate and maximum temperature reached by the samples. The temperature-time experimental curves are compared with theoretical heating curves to verify if the model can be used to predict the temperature evolution at the joining interface during a welding process.

İtfaiyeciler, genellikle tehlikeli koşullar altında dinamik aktiviteler gerektiren olaylara müdahale etmektedirler. Olaylara müdahale ettikleri esnada denge sorunları sebebiyle düşüp yaralanmaktadırlar. Core kaslarındaki yorgunluğun, dinamik dengenin azalmasına sebep olduğu ve denge kayıpları ile sonuçlandığı yapılan çalışmalarda bildirilmektedir. Bu çalışma, iftaiyeci adaylarının core kas dayanıklılığı ile dinamik denge performansları arasındaki ilişkilerin değerlendirilmesi amacıyla planlanmıştır. Ortalama yaşları 19,11±1,34 yıl, ortalama boy uzunlukları 176,06±6,56 cm ve ortalama vücut ağırlıkları 69,36±12,25 kg olan, toplam 26 erkek itfaiyeci adayı, basit rastgele örnekleme yöntemi ile araştırma için seçilmiş ve araştırmaya gönüllü olarak katılmıştır. Katılımcılara antropometrik (boy uzunluğu, kol boyu uzunluğu, bacak boyu uzunluğu, vücut ağırlığı, beden kitle indeksi ve vücut yağ yüzdesi) ve performans (core kas dayanıklılığı ve dinamik denge) ölçümleri uygulanmıştır. İtfaiyeci adaylarında core kas dayanıklılığı ile dinamik denge kompozit skorları arasındaki ilişkiler incelendiğinde, gövde ekstansiyon ile alt ekstremite sağ kompozit (r=0.558, p
