Published: December 2024

This study was carried out to identify and estimate the prevalence of intestinal helminths in free-range poultry (Gallus gallus domesticus), from September 2016 to December 2022. A total of 494 birds of both sexes, aged from 6 weeks to 36 weeks, were examined and necropsied. Mucosa and contents of different gastrointestinal tract segments were examined for the helminth parasites. Results showed that 38.86% (192 birds), as overall prevalence, were infected by at least one parasite species. The prevalence of gastrointestinal helminth infections was higher in young animals (under 18 weeks) (32.79%) than adults (6.07%) (p < 0.05) and during rainy and cold seasons (autumn: 59.18%; spring: 41.72%; summer: 30.7%; winter: 28.84%) (p < 0.05). Nematodes were more prevalent (30.97%) than cestodes (21.66%). The prevalence was significantly higher in young chickens compared to adult animals (p < 0.05). Among the helminths species, Raillietina genus was the most observed (22.67%) (Raillietina echinobothrida: 21.05%; Raillietina spp: 1.62%) followed by Ascaridia galli (21.25%), Heterakis gallinarum (12.35%) and Capillaria spp. (4.86%). To our knowledge, this is the first report of gastrointestinal helminths prevalence in free-range chickens in the Northeast of Tunisia. Further additional studies are needed to develop better preventive measures in free-range poultry flocks.

Published: December 2024

The guppy (Poecilia reticulata) is one of the world's most popular freshwater aquarium fish. The present study aims to determine the cause of mortality in guppies obtained from the ornamental fish farm in Istanbul province and to detect tissue damage. Externally diseased guppies showed sloughing scales and large ulcerative skin lesions on the body surface. Bacteriological inoculation from internal organs was made onto Tryptic Soy Agar (TSA). After incubation, isolated bacteria were identified as Aeromonas hydrophila and Vibrio parahaemolyticus according to their physiological, morphological, and API 20E profile. As a result of the parasitological examination, Tetrahymena sp. and Myxobolus sp. were found on the skin and intestinal lumen of the diseased guppy, respectively. Histopathologically, cytoplasmic vacuolation in the liver, degeneration, and necrosis of the tubular epithelium and granuloma-like structure in the kidney, vacuolization of epithelial cells in the intestinal lumen, hyperplasia of the gill and Tetrahymena sp. between necrotic muscles were observed. Interestingly, Myxobolus sp. spores were only detected in the intestinal lumen. Co-infection of guppies was determined to cause severe disease with high mortality and tissue damage. The synergistic effects of pathogens may cause more damage to diseased guppies. This report is the first detailed report containing new histopathological findings of tetrahymeniosis and the first detection of Myxobolus sp. in the gut of diseased guppy in Turkey.

Published: December 2024

In contemporary agricultural practices, it is increasingly difficult imagine production processes that are unaffected by the challenges posed by climate change. The aflatoxin B1 (AFB1) is a mycotoxin which was not very prominent in food and feed in Europe. However, in recent decades, climate change has emerged as a significant issue, raising concerns about food safety and animal production. One of the main problems regarding AFB1 is an uneven distribution in feed samples, and quite often feed sample analysis does not provide a proper insight into the exposure to this mycotoxin. This study aimed to investigate the occurrence of AFB1 in feed and its biomarker aflatoxin M1 (AFM1) in urine of fattening pigs on one small family farm. Urinary biomarker levels were subsequently used to estimate the probable daily intake and concentration of AFB1 in feed, employing established mathematical models. Four samples of a complete feeding mixture for fattening pigs originating from one farm were analyzed and the average AFB1 concentration of 0.046.3±0.0048 mg/kg was determined. Seven urine samples collected from the slaughter fatteners that were fed the above mentioned feed were analyzed for AFM1 levels. All samples contained AFM1, with an average concentration of 6.7±2.7 µg/l. The estimation of the AFB1 daily intake enabled us to assess the level in feed. The mathematical model revealed a level of 0.269 mg/kg that overestimated the AFB1 content obtained by analyzing the feed.

Human stress levels escalated amid the COVID-19 epidemic as a result of restrictions on social interactions and movement. Furthermore, due to the lack of awareness about the disease's characteristics, numerous cases of violations of animal welfare occurred. The study is focused on the macro-level analysis regarding the impact of COVID-19 on human-pet interactions in Malaysia and Indonesia. A total of 1,829 tweets related to human-pet interactions during COVID-19 were retrieved from Twitter between March 17th and September 17th, 2020. Natural Language Toolkit (NLTK) was utilized to analyze the tweets with human moderation. The analysis revealed a large number of neutral and positive sentiments in the initial stage of the study. Later, positive public sentiment (50%, n = 27/54) rose in Malaysia significantly as the Twitter users were demanding justice for the abused animals. Meanwhile, the sentiments in Indonesia were predominantly both neutral (42%, n = 52/123) and positive (34%, n = 42/123), with the sentiment shifting after an incidence of animal cruelty went viral. Following a study in the United Kingdom reporting positive COVID-19 cases in cats, an upward trend in negative public reaction was observed in Malaysia (35%, n = 7/20) and Indonesia (48.8%, n = 40/82). In conclusion, the public sentiment regarding the impact of COVID-19 on human-pet interactions affects individuals due to the associated health risks.

Published: December 2024

Pig production in Uganda is a thriving business as the demand for pork and pork products is increasing. Pork consumption per capita in Uganda is estimated to be 3.5 kg and is considered the highest in Africa. Pig production is, however, limited by several factors, including endemic diseases, particularly African swine fever (ASF), which can result in up to 100% mortality. The factors responsible for ASF outbreaks are poorly understood, especially at farm level.  A study conducted in Kasawo and Katosi sub-counties between February and March 2023 aimed to examine biosecurity and husbandry practices on pig farms. A questionnaire was distributed to pig farmers and a Focus Group Discussion (FDG) of animal health care workers was held. Blood samples were collected from pigs of all ages and sex in the two sub counties and ASF virus antibodies were tested using competitive ELISA. Out of the 777 collected blood samples, none was seropositive for ASF virus antibodies. Of the 292 households sampled, 70% kept their pigs indoors, while only 0.7% had fenced enclosures, and 4% had functional foot baths. The FGD revealed that animal health workers, who were on daily calls, carried disinfectants to sanitize their personal protective equipment (PPE) every time they left a farm. The lack of centralized slaughter facilities was identified as a key factor contributing to the spread of the ASF virus, as well as the panic selling of pigs during suspected ASF outbreaks. Sharing boars, purchasing and stocking pigs without veterinary health certification were identified as contributing factors. The results from this study showed that although active ASF infections were not found in pigs, the district experienced ASF outbreaks in the past. The study concluded that educating farmers about the spread and prevention of ASF, ensuring ongoing disinfection of PPE by animal health professionals, and establishing pig slaughter facilities could help eliminate ASF transmission and spread in the area.

Authors: Dilek Tepe Hafize , Doyuk Fatma
Published: December 2024

In this study, the bioactive components and antioxidant properties of Althaea (Hatmi) and Hibiscus plants were assessed using various methods. Both aqueous and ethanol extracts of these plants yielded distinct and effective results. Antioxidant activity was evaluated using 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), and Ferric Reducing Antioxidant Power (FRAP) assays at concentrations of 25, 50, 75, and 100 mg/mL. Hatmi extracts, both ethanol and aqueous, exhibited high DPPH activity, particularly at 75 and 100 mg/mL, while Hibiscus showed a linear increase in DPPH activity with concentration, reaching 2000 µM Trolox Equivalent (TE) /g dry weight (DW) at 100 mg/mL. In ABTS assays, lower concentrations of ethanol extracts were more effective, but higher aqueous concentrations showed greater activity. FRAP results indicated high antioxidant activity in Hatmi ethanol extracts, with activity reaching 2700 µM TE/g DW at higher concentrations. Phenolic analysis revealed high levels of apigenin 7-glucoside, hesperidin, and caffeic acid in Hatmi, while Hibiscus extracts contained significant amounts of chlorogenic acid and quercetin. Gas Chromatography-Mass Spectrometry (GC-MS) analysis showed that Hatmi had a higher abundance of volatile organic compounds compared to Hibiscus.

Published: December 2024

Plantago major L. (P. major) is a plant used by people for medicinal purposes. In this study, ethanol extract was prepared after species identification of P. major plant growing in Varto district of Muş. Phenolic content and amount were determined by high pressure liquid chromatography (HPLC). Four different methods were used for antioxidant activities. As a result of the chemical content analysis of the plant, the highest amount of trans-p-cumaric acid (89.0 ng/μL), abscisic acid (11.4 ng/μL) and salicylic acid (8.20 ng/μL) were detected. When the antioxidant results were evaluated, it was observed that the extract scavenged DPPH and ABTS radicals with a power close to that of standard antioxidants. At the same time, the extract significantly reduced Fe+3 and Cu+2 ions. It was found that the activity of the samples generally increased with increasing absorbance. The fact that there are few studies on the antioxidant activity of P. major in the literature makes this study even more important. We hope that this study will shed light on future research on this species.

Authors: Kara Hanife , Uzun Mahir
Published: December 2024

Gears are machine elements widely used in the industry. A gear mechanism can consist of two gears, or machines with many gears of different sizes can be used. Particularly when many gears are used, this significantly increases the weight and cost of the machine. With the advancement of technology in recent years, production methods have also developed, making it possible to manufacture parts with almost any geometry. In this study, utilizing the capabilities of advanced production methods, designs with triangular, square, and hexagonal geometries were made on the body of a spur gear to minimize the weight of the gear. To find the lightest gear that can work without damage, different designs with various edge lengths and fill thicknesses were modeled separately using the Solidworks software package. The finite element analysis of the modeled gears was performed using the ANSYS software package. As a result of the analyses, among the gears with three different designed geometries and hollowed bodies, the gear with a square profile achieved the lightest weight. Compared to the solid-bodied gear, a significant weight reduction of 63,65% was achieved with this designed gear.

Published: December 2024

Cisplatin is one of the most active cytotoxic agents used mainly in the treatment of solid tumors. High doses and long-term use of Cisplatin are known to cause cardiotoxicity. In recent years, the antiapoptotic and antioxidant effects of Carvacrol in cardiovascular diseases have attracted attention. In this study, the effects of Carvacrol on Cisplatin-induced cardiotoxicity in a rat model were investigated using biochemical and histological methods. Twenty-eight rats were divided into 4 groups: 1. Control group, 2. Carvacrol group, 3. Cisplatin group, 4. Cisplatin + Carvacrol group. The expression of antioxidant enzymes, proinflammatory cytokines, apoptotic, and autophagic proteins was examined in heart tissue obtained from rats sacrificed after the last drug administration. Additionally, heart tissue was evaluated histopathologically. Cisplatin has been observed to cause oxidative stress and inflammatory damage in animal heart tissue. Carvacrol administration significantly increased antioxidant enzyme (superoxide dismutase and glutathione peroxidase) activities while suppressing inflammatory markers (NF-κB, TNF-α, IL-1β). Additionally, Cisplatin induced apoptotic (caspase-3, Bax, Bcl-2) and autophagic (Beclin-1, LC3A, LC3B) markers. It has been determined that carvacrol can protect heart tissues from the destructive effects of cisplatin by exerting anti-apoptotic and anti-autophagic effects. The expression levels of Notch1 and Hes1, which were decreased by cisplatin administration, were upregulated after administration of Carvacrol. H&E staining results showed that Carvacrol preserved myocardial tissue integrity. In conclusion, Carvacrol showed a cardioprotective effect against cisplatin-induced cardiotoxicity.

Authors: Onishchenko I.N. , Taran G.V. , Zamuriev O.O. , Opalev P.O.
Published: December 2024

Researches were conducted on the electrodynamics’ characteristics of gas discharge in a needle-plane electrode system with one liquid electrode under the application of high voltage of two types: unipolar negative pulse and combined (sum of DC and high-frequency AC high voltage) ones. This is necessary in many applications, particularly for water purification. Metal needle electrodes made of stainless steel were used, some of which were subjected to various treatments (polishing, coating with zinc nitride, titanium nitride or titanium oxide). It was
shown that applying combined high voltage in the electrode system with a nitride coating results in a mean current 2 times smaller. When using a unipolar negative high-voltage pulse, the maximum mean discharge current was obtained with the untreated electrode system. This is due to the presence of a greater number of micro-protrusions on the needle electrodes, which leads to increased electric field intensity in the generation zone.

Complex Eigenvalue Analysis of a Linear Pencil: An Experimental Study
Authors: Öztürk Hasen Mekki
Published: December 2024

This paper is concerned with a finite-dimensional example of a linear pencil which leads to a class of non-self-adjoint matrices. We consider the linear pencil $H_c-\lambda L$, where $H_c$ is a tri-diagonal matrix with a constant parameter $c$ on the main diagonal and off-diagonal entries equal to one, and $L$ is a diagonal matrix whose elements decrease linearly from one to minus one. In general, the spectra of operator polynomials may contain non-real eigenvalues as well as real eigenvalues. Nevertheless, they exhibit certain patterns. Our aim in this research is to carry out a variety of numerical investigation on the eigenvalues so as to understand the eigenvalue behaviour of such pencils from different points of view. In accordance with our numerical findings, a series of conjectures are offered and various heuristics has been discussed.

Published: December 2024

In this research, we present the notion of statistical compactness restricted up to order $\alpha$, where $\alpha \in (0,1]$. There exist statistically compact spaces that are not compact. So the parameter $\alpha$ became the measurement of non compactness. Additionally, we looked for the continued existence of order $\alpha$ statistical compactness under open continuous surjection and sub-space topology. A finite intersection-like characterization for $\alpha$ statistical compactness has also been established.

The Disadvantages of Lead Aprons and the Need for Innovative Protective Clothing: A Survey Study on Healthcare Workers' Opinions and Experiences
Authors: Şahin Meryem Cansu , Ünay Çubukçu Nilüfer , Oner Eren
Published: December 2024

The use of state-of-the-art technical textiles instead of lead aprons is of great importance due to their lightweight, flexible, non-toxic and comfortable composition. In this study, we aimed to determine the disadvantages experienced by healthcare workers due to lead aprons and their opinions about innovative protective clothing. The survey, comprising seventeen questions, aimed to gather demographic information, design and physical properties of respondents' lead aprons, functionality, comfort, and performance of current protective clothing, and determine future design requirements. Within the scope of the research, a survey was administered to 52 radiation workers, and the results were analyzed statistically. Radiology technicians comprised nearly half of the respondents (34%), followed by physicians (25.5%) and nurses (19.1%). The most important problems encountered by the respondents during the use of lead aprons were defined as being heavy, restricting movement, and not fitting the body properly. Among the comfort descriptors, inability to move comfortably, weight and air permeability were considered "completely important" by the respondents, respectively. The study showed that 26.92% of the participants experienced complications with their lumbar spine, while 23.08% reported concerns with their cervical spine. Survey participants noted low air permeability and thermal comfort in lead aprons, making them unsuitable for various anatomical structures. To overcome these issues, technical textiles with easier shapeability and improved performance, such as mechanical properties and insulation, could be used instead.In order to overcome these disadvantages, producing and using technical textiles instead of lead aprons will provide a significant advantage.

In this study well-blended Erbium:Cerium oxide doping polyethylene/ polyvinylpyrrolidone blended polymer films were synthesized using a simple solution casting synthesis approach. The changes in crystallization behavior, and luminescence and structural properties of polyethylene glycol and polyvinylpyrrolidone with the addition of cerium oxide and erbium ion have been investigated through FT-IR spectroscopy, X-ray diffraction and luminescence properties. The results show that adding the proper amount of CeO2:Er3+ nanoparticles can play the role of the further nano-filler, which is beneficial to improve the luminescence of blended oxide film. This study contributes to the understanding of the role of interfacial sites in metal and oxide support in blended films for the development of fertile luminescence materials.

Lojistik faaliyetleri, ulusal ve uluslararası ticarette önemli bir rol oynar ve firmalar için önemli bir maliyet kalemidir. Ülkeler, lojistik performanslarını diğer ülkelerle kıyaslayarak rekabet güçlerini artırabilir ve iyileştirme yapmaları gereken alanları belirleyebilirler. Bu kapsamda bazı ülkelerin talebi üzerine Dünya Bankasına bağlı Uluslararası Ticaret Birimi 2007 yılında ülkelerin Lojistik Performans Endeksini (LPE) yayınlamıştır. İki yılda bir Dünya Bankası tarafından yayınlanan LPE, listede yer alan ülkelerin diğer ülkeler ile durumunu değerlendirebilmesi için göz önünde bulundurması gereken bir veri haline gelmiştir. LPE’de gümrük, lojistik hizmetlerin kalitesi, altyapı, uluslararası sevkiyat, gönderilerin takibi ve izlenebilirliği ile zamanında teslimi şeklinde olmak üzere 6 farklı kriter ölçek olarak belirlenmiştir. Bu kriterler Uluslararası Lojistik Performans Endeksi adı altında puanlanmaktadır.
Bu çalışmada, performans ölçüm yaklaşımları ve ölçütleri açıklandıktan sonra, Türkiye’nin yıllara göre Lojistik Performans Endeksi incelenmiş ve Dünya Bankası verileri ile Türkiye’nin Lojistik Performans Endeksi verileri, betimsel tarama yöntemiyle endeksteki kriterler bazında eksik ve zayıf yönleri değerlendirilmeye tabi tutularak yorumlanmıştır.

The ruins of Castle Pyšolec (Žďár nad Sázavou District) stand above the regulation reservoir of the Vír Dam on the River Svratka. Originally built as a residential castle by the lords of Pernštejn, the Moravian margraves were also important owners. The exact date of its foundation is not mentioned in any written sources and its history can be traced only to the 14th century. The castle was abandoned before 1464. A survey of the site adjacent to the slope below its northern pillar brought a large collection of finds reflecting life in
the medieval castle. Most common in the ensemble are common utility ceramics of regional origin, as well as builders’ hardware, finds proving the use of horsepower and animal bones. More precious artefacts include coins and items of personal belongings, which are proof of the more privileged position of their holders.

Purpose. To determine the effect of the method (split application of fertilisers in autumn and spring) of applying the maximum recommended rate of nitrogen fertilisers of 60 kg/ha on the formation of the productivity of winter pea variety ‘NS Moroz’.
Methods. The research was conducted in the fields of Agrofirma Sylchenkove (Talalaiv district, Chernihiv region) in 2022–2023 on podzolized chernozems. The following fertilisation treatments were studied: 1. P45K45 (background); 2. N15P45K45; 3. N15P45K45 + N15; 4. N15P45K45 + N30; 5. N15P45K45 + N45; 6. N30P45K45; 7. N30P45K45 + N15; 8. N30P45K45 + N30; 9. N45P45K45; 10. N45P45K45 + N15; 11. N60P45K45. The sowing area was 25 m2, the recorded area was 20 m2.
Results. The highest yield of winter peas variety ‘NS Moroz’ (3.92 t/ha) on podzole chernozems of the Chernihiv region was formed by applying the start dose (15 kg/ha) of nitrogen mineral fertilisers in the main fertilisation in autumn and 45 kg/ha in the early spring after recovery of vegetation. Nitrogen fertilisers applied in early spring at the rates from 15 to 45 kg/ha against the background of N15P45K45 had a positive effect on the formation of taller winter pea plants with more beans and a higher 1000-kernel weight. The application of nitrogen mineral fertilisers in spring helped to increase the average height of plants by 9.5 cm, the number of beans per plant by 1.6, and the 1000-kernel weight by 19.7 g. The highest protein content in pea grains (23.4%) was provided by the complex application of N15P45K45 in autumn application and N45 in early spring.
Conclusions. To obtain a yield of winter pea on podzolic chernozems of the Chernihiv region at the level of 3.5–4.0 t/ha, it is recommended to apply fertilisers N15P45K45 in autumn during the main tillage and N15–45 in spring.

Purpose. To determine the effect of different concentrations of cadmium salt on the growth and development of shoots of different sorghum species in vitro and to select tolerant forms for developing breeding genotypes resistant to abiotic factors.
Methods. The study involved different sorghum species: grain, broomcorn, Sudan grass, and soryz. Sorghum bicolor cultivar 'Stepovyi 8' was used as a control. Nutrient media were prepared using the standard Murashige and Skoog (MS) formulation. Sorghum seeds were sterilized with a solution of Bilyzna (bleach). Clonal micropropagation was conducted through direct selection with the addition of cadmium chloride (CdCl₂) and cadmium sulfate (CdSO₄) at concentrations ranging from 1.0 to 45.0 mg/L. The resulting shoots were evaluated on days 3 and 7 for the percentage of viable, necrotic, and dead shoots, as well as their biometric parameters.
Results. The tolerance levels of sorghum plants varied depending on the species, the type of cadmium salt, and the salt concentration. Sudan grass exhibited the highest tolerance, whereas broomcorn was the most sensitive. This trend was consistent for both cadmium chloride and cadmium sulfate. At a concentration of 10.0 mg/L CdCl₂, shoot viability remained high in all treatments (82–95%). Increasing the concentration to 15.0 mg/L reduced viability to 70–87%, while at a concentration of 20.0 mg/L, it dropped to 44–54%. Concentrations of 30.0 mg/L and higher were critical, reducing shoot viability to 2–12%. The maximum toxic concentration (45.0 mg/L) caused the death of broomcorn shoots. In comparison, CdSO₄ demonstrated lower toxicity under similar conditions. At a concentration of 10.0 mg/L, shoot viability was 90–98%, while at a concentration of 15.0 mg/L, it was 80–95%. Even at higher concentrations (20.0–25.0 mg/L), viability remained higher compared to CdCl₂, and the maximum concentrations provided survival of a small proportion of viable shoots (up to 6%). Necrotic shoots began to appear at CdCl₂ concentrations as low as 7.5 mg/L, with the highest percentage of necrosis recorded in broomcorn plants. CdSO₄ caused less necrosis, even at higher concentrations (10.0–17.5 mg/L), indicating its reduced toxicity. At low cadmium salt concentrations (1.0–5.0 mg/L), the number of newly formed shoots was high in all treatments. CdSO₄ promoted greater shoot formation compared to CdCl₂. At 1.0 mg/L, the number of new shoots ranged from 7 to 18, while at 15.0 mg/L, this number decreased to 2–10.
Conclusions. CdSO₄ is a less toxic alternative to obtain viable sorghum shoots in cadmium-containing media. The best results were observed at concentrations up to 10.0 mg/L, particularly for Sudan grass and soryz. Breeding programs should consider the species-specific tolerance of sorghum to heavy metals, with special attention to Sudan grass as the most tolerant species.
