The effect of fruit position and bagging treatment on Gamboge disorder in mangosteen (Garcinia mangostana L.)
Authors: AKMAL Ajmir , SANTOSA Edi , POERWANTO Roedhy , DEWI Elvira Sari
Published: April 2023

Gamboge disorder has a detrimental effect on mangosteen. The leakage of the gamboge may result from water availability. Thus, modifying the transpiration of the fruit by bagging might minimize the inappropriate leak of the gamboge produced by the fruit. The study’s objective was to understand the relationship between different fruit positions and bagging treatment on the gamboge disorder in mangosteen. The experiment was conducted on 10-years old trees by tagging young fruits, five replicates with two fruit positions (inside and outside), and bagging treatment (no bagging, transparent and black plastic bagging). The result showed that bagging the fruits inside the canopy does not affect fruit mass. However, bagging with transparent and black plastic of the fruits inside the canopy decreases fruit size. The fruit quality improves by black bagging on the inside canopy fruits. These findings demonstrate that bagging fruits outside the canopy lowers their quality. Black bags used to package fruits inside the canopy improve fruit quality. However, the treatment also causes more fruit to fall from the tree and decreases the nutrient content.

In recent decades, global production of poultry meat has increased due to its affordable prices and good nutritional value. The latter has been achieved by intensive selection of broilers for increased growth rate, feed efficiency, breast yield and reduced abdominal fat deposition. On the other hand, intensive selection and increasing demand for poultry meat, as well as some environmental stressors, such as changes in environmental temperature, feeding regime, breeding technology, and improper handling procedures before slaughter, lead to increased susceptibility of animals to oxidative stress, resulting in poorer sensory and technological characteristics of chicken meat. As a result of intensive broiler production and the increase in breast muscle, various breast muscle abnormalities or myopathies have been observed. The most common ones include deep pectoral myopathy, pale, soft and exudative like meat, white striping, wooden-breast and spaghetti meat, which mainly affect the pectoralis major breast muscle and negatively influence the sensory and technological characteristics of breast meat. The muscle abnormalities have a detrimental effect on quality and nutritional value of meat, affect consumer compromise consumers acceptance, and cause economic losses in the meat processing industry.
Agroecological zones influence maize infestation and damage severity by the fall armyworm (Spodoptera frugiperda [J. E. Smith, 1797]) in southwestern Nigeria
Authors: OJUMOOLA Olusegun Adebayo , OMOLOYE Adebayo Amos
Published: April 2023

The fall armyworm (Spodoptera frugiperda) is an invasive and highly destructive insect pest that has caused extensive damage to maize in Africa since its first report on the continent in 2016. Information on fall armyworm infestation and damage within African agroecologies is essential for the development of appropriate pest management strategies, but these are scant in Nigeria. Consequently, in this study, fall armyworm infestation levels and severity of damage to maize in the three major maize-growing agro-ecological zones (humid forest, derived savanna, and southern guinea savanna) of southwestern Nigeria was investigated using standard field sampling protocols. Results showed that maize infestation and damage severity varied across agroecological zones, with the humid forest being the most impacted. Information provided will enhance decision-making for effective management of the fall armyworm in southwestern Nigeria.
Vplivi salicilne kisline in njenih derivatov na rastline, škodljive in koristne organizme in njihove interakcije v okolju

Published: April 2023

Svetovna proizvodnja hrane je prisiljena v iskanje novih pristopov za zaščito rastlin pred škodljivimi organizmi in okoljskimi dejavniki. Ena izmed alternativ, bi lahko bila uporaba salicilne kisline (SA) in njenih derivatov. Na splošno so učinki SA na primarni ravni ekosistema, vzpodbudni, saj pripomorejo k izboljšani produktivnosti in kakovosti številnih rastlin ter izboljšujejo toleranco na številne stresorje. Sekundarna raven učinkov SA v okolju predstavlja učinke na škodljive organizme zaradi direktnega delovanja in tudi posrednih učinkov SA, ki nastanejo zaradi morfoloških in fizioloških sprememb, ko se rastlina prilagaja stresorjem. SA v veliko primerih vpliva na zmanjšanje okužb, na nekatere škodljivce pa deluje tudi odvračalno. Rastline po napadu škodljivega organizma sproščajo v okolje hlapne spojine, predvsem derivate SA kot je metilirana SA (MeSA). Ta privablja naravne sovražnike škodljivcev, kar bi se lahko uvedlo v varovanje rastlin pred škodljivimi organizmi, saj je bilo ugotovljeno pri številnih vrstah, da MeSA nanje deluje kot atraktant. Salicilati imajo zelo širok spekter delovanja, ki v okolju sprožajo različne vplive, ki se med seboj prepletajo in posledično vplivajo na več ravni v eksosistemu. V tem članku smo učinke salicilatov razdelili glede na različne nivoje v okolju, kar nam je dalo širši vpogled na potencialno uporabo salicilatov v kmetijstvu.
Infrabrow excision with septo-myocutaneous flap repositioning in aged eyelids in Asians
Authors: Park Jong Hyun , Lim Nam Kyu
Published: April 2023

Asian eyelids are characteristically puffy, with a fold, and have bulging of the orbital fat and septum. Moreover, with the aging process, the orbital septum and skin lose elasticity and orbital fat atrophy proceeds, thus resulting in dermatochalasis and a sunken eyelid. We introduce a modified technique of infrabrow excision with septo-myocutaneous flap repositioning. An upper incision was made along the lower margin of the eyebrow and the placement of the lower incision was decided according to the amount of skin excision needed. After skin removal, the orbicularis oculi muscle (OOM) was incised 2 mm above the lower margin and dissected to expose the orbital septum. Additional dissection was performed along the preseptal plane to the supraorbital rim periosteum. Then, the lower flap (septo-myocutaneous flap) was anchored to the supraorbital rim periosteum. The overlapping OOM and subcutaneous layers were sutured separately. This technique makes it possible to correct the cause of an aging eyelid appearance. Additionally, an overlapping OOM aids in correcting sunken eyelids, and by tensioning the orbital septum, a puffy eyelid is corrected. As an advantage over the conventional infrabrow excision, our method prevents recurrence and corrects orbital septum laxity. Therefore, it can achieve more natural outcomes and lower recurrence rates.

Meta-analysis of the rs231775 locus polymorphism in the CTLA-4 gene and the susceptibility to Graves’ disease in children
Authors: Shi Mili , Liu Xiaobo , Song Qiuyan , Shi Yijie , Tai Qirui
Published: April 2023

The aim of this study was to systematically evaluate the correlation between the rs231775 locus polymorphism in the cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) gene and genetic susceptibility to Graves’ disease (GD) in children. Some studies found that the CTLA-4 gene polymorphism was associated with GD in children. The data up to February 2022 were retrieved from the databases. Stata 15.0 software was used for meta-analysis. A total of seven studies were included in our research. The results of the meta-analysis showed that the rs231775 locus polymorphism in the CTLA-4 gene in general and Asian populations was correlated with children’s susceptibility to GD (A vs G: OR = 0.75, 95% CI (0.660–0.86); GG vs AA: OR = 1.34, 95% CI (1.04–1.73); AG vs AA: OR = 1.32, 95% CI (1.02–1.10); AG + GG vs AA: OR = 3.81, 95% CI (2.17–6.70); GG vs AA + AG: OR = 1.23, 95% CI (1.05–1.45)). In summary, the rs231775 locus polymorphism in the CLTA-4 gene may be a risk factor for GD in Asian children. The G allele may be a susceptibility factor, while the allele A may be a protective factor against GD in Asian children. In the future, more large-scale studies may be needed to verify our results.
Parameter-based patient-specific restoration of physiological knee morphology for optimized implant design and matching
Authors: Grothues Sonja , Becker Ann-Kristin , Hohlmann Benjamin , Radermacher Klaus
Published: April 2023

Total knee arthroplasty (TKA) patients may present with genetic deformities, such as trochlear dysplasia, or deformities related to osteoarthritis. This pathologic morphology should be corrected by TKA to compensate for related functional deficiencies. Hence, a reconstruction of an equivalent physiological knee morphology would be favorable for detailed preoperative planning and the patient-specific implant selection or design process. A parametric database of 673 knees, each described by 36 femoral parameter values, was used. Each knee was classified as pathological or physiological based on cut-off values from literature. A clinical and a mathematical classification approach were developed to distinguish between affected and unaffected parameters. Three different prediction methods were used for the restoration of physiological parameter values: regression, nearest neighbor search and artificial neural networks. Several variants of the respective prediction model were considered, such as different network architectures. Regarding all methods, the model variant chosen resulted in a prediction error below the parameters’ standard deviation, while the regression yielded the lowest errors. Future analyses should consider other deformities, also of tibia and patella. Furthermore, the functional consequences of the parameter changes should be analyzed.
Interactions of Na+/taurocholate cotransporting polypeptide with host cellular proteins upon hepatitis B and D virus infection: novel potential targets for antiviral therapy
Authors: Zakrzewicz Dariusz , Geyer Joachim
Published: April 2023

Na+/taurocholate cotransporting polypeptide (NTCP) is a member of the solute carrier (SLC) family 10 transporters (gene symbol SLC10A1) and is responsible for the sodium-dependent uptake of bile salts across the basolateral membrane of hepatocytes. In addition to its primary transporter function, NTCP is the high-affinity hepatic receptor for hepatitis B (HBV) and hepatitis D (HDV) viruses and, therefore, is a prerequisite for HBV/HDV virus entry into hepatocytes. The inhibition of HBV/HDV binding to NTCP and internalization of the virus/NTCP receptor complex has become a major concept in the development of new antiviral drugs called HBV/HDV entry inhibitors. Hence, NTCP has emerged as a promising target for therapeutic interventions against HBV/HDV infections in the last decade. In this review, recent findings on protein–protein interactions (PPIs) between NTCP and cofactors relevant for entry of the virus/NTCP receptor complex are summarized. In addition, strategies aiming to block PPIs with NTCP to dampen virus tropism and HBV/HDV infection rates are discussed. Finally, this article suggests novel directions for future investigations evaluating the functional contribution of NTCP-mediated PPIs in the development and progression of HBV/HDV infection and subsequent chronic liver disorders.
Investigating willingness to communicate vis-à-vis learner talk in a low-proficiency EAP classroom in the UK study-abroad context
Authors: Zhou Qianqian
Published: April 2023

A large body of research has investigated the factors which underlie willingness to communicate (WTC). However, scant scholarly attention has been paid to WTC vis-à-vis learner talk, i.e., how intentions to talk translates into talk. Drawing on Dörnyei’s retrodictive qualitative modelling template, this research comprises a qualitative multiple-case study of three South Korean students who were learning English in a low-proficiency EAP classroom in the UK study-abroad context. Specifically, the study examined what factors facilitated or hindered their WTC-talk realisation. Methodological triangulation was achieved by means of classroom observations, audio-stimulated recall interviews and semi-structured interviews. Findings revealed five individual factors and four contextual factors which formed various interactional patterns and interdependently influenced the three students’ WTC-talk realisation. Such interactional patterns showcase how individual and contextual factors interact and contribute to WTC and individual differences in communication frequency in the EAP classroom. The study provides novel empirical evidence for the influence of the Korean Confucian-based culture of learning and communication on students’ L2 practice. Informed by the complex dynamic systems theory, the study concludes with pedagogical implications that aim to inspire EAP practitioners to cultivate WTC-friendly classes that optimise the realisation of learner talk.
Computational analysis of nuclear desalination system under various configurations
Authors: Ud-Din Khan Salah , Orfi Jamel
Published: April 2023

The research addressed the economic evaluation of nuclear energy, coal, oil and natural gas in various cycle configurations with different distillation technologies. A comparison between fossil and nuclear energy sources is discussed. A comprehensive review of all desalination plants using fossil and nuclear energy with cogeneration is also included and discussed. Computational model was used to evaluate nuclear and non-nuclear desalination plants. Four possibilities were discussed. In this first case, a nuclear gas cycle integrated with a MED desalination plant was found to have the lowest cost in the gas cycle. While the nuclear steam cycle integrated with RO has the lowest cost compared to oil and natural gas. In the third case, the combined nuclear cycle was discussed and it was found that the combined nuclear cycle associated with RO has the lowest cost. In the last case, the evaluation of a heat-only desalination plant was conducted among all sources, and it was found that the nuclear plant with RO and MED has the lowest cost. In addition, the completed nuclear desalination plant was subjected to five scenarios to calculate and estimate at which capacity the plant provides the best values. The results show that nuclear desalination with gas cycle is the most economical among the oil and natural gas options.
A self-adaptive inertial extragradient method for a class of split pseudomonotone variational inequality problems
Authors: Owolabi Abd-Semii Oluwatosin-Enitan , Alakoya Timilehin Opeyemi , Mewomo Oluwatosin Temitope
Published: April 2023

In this article, we study a class of pseudomonotone split variational inequality problems (VIPs) with non-Lipschitz operator. We propose a new inertial extragradient method with self-adaptive step sizes for finding the solution to the aforementioned problem in the framework of Hilbert spaces. Moreover, we prove a strong convergence result for the proposed algorithm without prior knowledge of the operator norm and under mild conditions on the control parameters. The main advantages of our algorithm are: the strong convergence result obtained without prior knowledge of the operator norm and without the Lipschitz continuity condition often assumed by authors; the minimized number of projections per iteration compared to related results in the literature; the inertial technique employed, which speeds up the rate of convergence; and unlike several of the existing results in the literature on VIPs with non-Lipschitz operators, our method does not require any linesearch technique for its implementation. Finally, we present several numerical examples to illustrate the usefulness and applicability of our algorithm.
Cd(II) and As(V) removal from the multicomponent solutions in the presence of ionic polymers using carbonaceous adsorbents obtained from herbs
Authors: Gęca Marlena , Wiśniewska Małgorzata , Nowicki Piotr , Jędruchniewicz Katarzyna
Published: April 2023

Biochars and activated carbons obtained from the nettle and the sage herbs were used for Cd(II), As(V), poly(acrylic acid) and polyethylenimine simultaneous adsorption from the multicomponent aqueous solutions. Electrokinetic studies proved that both activated carbons show acidic character of the surface. The point of zero charge of the sample obtained from the nettle herb occurs at pH 3.1, whereas that of the adsorbent obtained from the sage herb at pH 4.0. Cd(II) adsorption causes the decrease in the surface charge density and the zeta potential of both activated carbons, whereas As(V) addition results in the increase of solid surface charge density and its impact on the zeta potential value depends on adsorbent type. In case of the simultaneous presence of metals and polymers, the adsorbed macromolecules have greater influence on the surface charge density and the zeta potential values than the metal ions. Cd(II) and As(V) are well adsorbed on the examined activated carbons irrespective of the solution pH (changing in the range 3–9). Maximum adsorption were 218.27 mg/g for Cd(II) and 205.53 mg/g for As(V). The polymers presence causes a decrease (80–90 %) of both metal ions adsorbed amounts, whereas the poly(acrylic acid) and polyethylenimine adsorption mechanism in the presence of cadmium and arsenic ions depends on the adsorbent type and polymer-metal interactions.
Correlation between PSOGI pathological classification and survival outcomes of patients with pseudomyxoma peritonei treated using cytoreductive surgery and HIPEC: national referral centre experience and literature review
Authors: Martín-Román Lorena , Hannan Enda , Faraz Khan Mohammad , Müller Anna Sophia , Shields Conor , Aird John , Moran Brendan , Mulsow Jurgen
Published: April 2023

Objectives

The Peritoneal Surface Oncology Group International (PSOGI) consensus subdivided pseudomyxoma peritonei (PMP) into four groups according to histopathological features. The aim of this paper is to report survival outcomes after cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) from a national referral centre and to correlate the PSOGI classification with survival.

Methods

A retrospective study of a prospectively maintained database was performed. Consecutive patients treated with CRS + HIPEC for PMP of appendiceal origin were included (September-2013 to December-2021). Pathological features of the peritoneal disease were used to classify patients into the four groups proposed by PSOGI. Survival analysis was performed to evaluate the correlation of pathology on overall survival (OS) and disease-free survival (DFS).

Results

Overall, 104 patients were identified; 29.6 % were reclassified as acellular mucin (AM), 43.9 % as low-grade mucinous carcinoma peritonei (LGMCP), 22.4 % as high-grade MCP (HGMCP) and 4.1 % as HGMCP with signet ring cells (HGMCP-SRC). Median PCI and rate of optimal cytoreduction were 19 and 82.7 %, respectively. Median OS and DFS were not reached, 5-year OS and DFS were 88.6(SD 0.04) % and 61.6(SD 0.06) %, respectively. Log-Rank test revealed significant differences in terms of OS and DFS across the different histological subgroups (p<0.001 in both cases). However, histology did not retain its significance in the multivariate analysis for OS or DFS (p=0.932 and p=0.872, respectively).

Conclusions

Survival outcomes after CRS + HIPEC for PMP are excellent. The PSOGI pathological classification correlates with OS and DFS, but differences were not significant at multivariate analysis when adjusted for other prognostic factors.
Linguistic Contact in Perspective: Lateral Coda in Principense Portuguese
Authors: Balduino Amanda Macedo , Torres Vieira Nancy Mendes , Agostinho Ana Lívia
Published: April 2023

This paper discusses the lateral /l/ in coda in Principense Portuguese (PP). Based on an elicitedcorpusrecordedin situ, composed of 852 occurrences of 78 lexical items, we found that the lateral /l/ in coda can be vocalized or deleted. For instance,bolso‘pocket’ can be pronounced as [ˈbow.sʊ] or [ˈbo.sʊ], as reported in some Brazilian Portuguese varieties. In PP, vocalization and deletion are phenomena that arise from a confluence of factors. It gathers characteristic features of the formative grammatical structure of Portuguese. At the same time, it reflects the linguistic contact scenario in which PP is inserted, since the lenition of consonants in semivowels, as well as strategies to avoid codas, are also reported in Lung’Ie (LI), a language in synchronic contact and present in the constitution of the PP (Agostinho, Ana Lívia. 2015.Fonologia e método pedagógico do lung’Ie[Phonology and pedagogical method of Lung’Ie]. São Paulo: University of São Paulo dissertation). Both Portuguese and Lung’Ie support vocalization and deletion in their grammars, fostering a relevant overlap of features to the alternation [ɫ] ∼ [w] ∼ ∅ in PP. We conclude that, in addition to specific features of Portuguese grammatical structure, PP’s linguistic contact situation must be considered as a relevant factor for the deletion and vocalization of laterals in coda in PP.

Too WEIRD, Too Fast? Preprints About COVID-19 in the Psychological Sciences
Authors: Puthillam Arathy
Published: April 2023

That behavioral sciences are overrepresented by some countries, in terms of samples and authors, is a well-documented finding. Considering the immediate policy implications, the present study explored whether this bias also exists for research on the coronavirus pandemic. Preprints posted on PsyArXiv between two time periods in 2020 (March-April and May-December) with keywords related to “COVID-19” were sourced and their participant and author composition were assessed. Western and rich democracies were overrepresented in terms of authors and participants; preprints posted by authors from western and democratic countries were cited more and were published in journals with a higher impact factor. Implications, especially regarding a reductionist bifurcation of research as “WEIRD” or “non-WEIRD,” are discussed.

Published: April 2023

La presente investigación analiza la estrategia nacional llamada “Acompañamiento pedagógico” promovida por el Ministerio de Educación del Perú desde el año 2008, centrada en escuelas multi-grado rurales con lengua castellana y bilingues. La investigación se centra en los logros de aprendizaje de sus estudiantes así como evaluar y recomendar mejoras en su implementación. El primer objetivo fue determiner si existe diferencia significativa entre escuelas que han recibido acompañamiento pedagógico y aquellas que no han recibido en las pruebas nacionales tomadas a alumnus de segundo grado de primaria en comprensión lectora y matemáticas. Para ello se realizaron diversos tests de análisis de varianzas mixtas. Los hallazgos demuestran que han habido interacciones estadísticamente significativas entre recibir acompañamiento pedagógico por 3 años, lo cual indica que la estrategia es efectiva a fin de mejorar los aprendizajes de los estudiantes. La segunda meta de la investigación fue analizar la estrategia de acuerdo a la lógica subyacente en la política nacional de presupuesto por resultados en la que se enmarca la estrategia. Se realizó una revision y análisis documental, centrándose en el diseño lógico, focalización, organización y gasto público. Se encontraron inconsistencias en el diseño, problema de cobertura y la ausencia de estándares claros de organización.
Autoavaliação das Escolas. Reflexão em Torno da Melhoria do Sistema Educativo
Authors: Correia Esteves José Filipe
Published: April 2023

O presente artigo reflete sobre o sistema de autoavaliação e o seu potencial contributo na melhoria das práticas educativas. Para tal, efetuamos um estudo de caso único numa escola básica e secundária no concelho de Câmara de Lobos da Região Autónoma da Madeira. Como técnicas de recolha de dados foram aplicadas a entrevista semiestruturada, a observação natural e participante, bem como a análise documental. Para a análise e interpretação dos resultados obtidos foram utilizadas a análise de conteúdo e a triangulação. Constatou-se que a escola em estudo não aplica o modelo europeu CAF (Estrutura Comum de Avaliação), mas possui uma equipa de avaliação interna que faz o todo o tratamento qualitativo e estatístico dos mais variados dados, desde os resultados dos alunos, passando pelo nível de eficiência dos serviços escolares, entre outros. A escola implementa, assim, um sistema aberto e flexível de autoavaliação. No entanto, este sistema de avaliação da escola não permite a deteção dos seus pontos fracos e das suas áreas fortes, que possibilitem a construção de planos de melhoria, pois só assim a escola estaria mais apta a responder ao desafio de uma possível atividade de avaliação externa. Concluímos que, a implementação na escola de um modelo de gestão de qualidade deverá assentar em finalidades, delineadas expressamente, tendo em conta o universo em particular e que seja exequível. Para tal, a escola deve adotar instrumentos de observação e análise que permitam efetivar linhas de diagnóstico para aperfeiçoar práticas e melhorar o sistema educativo.

Published: April 2023

Se describe la aplicación de inteligencia artificial basada en el modelo de regresión lineal múltiple con gradiente descendiente estocástica con la finalidad de determinar la calidad de la fibra de alpaca Huacaya de color blanco. Se analizaron 1200 fibras correspondientes a seis muestras de alpaca. Las fibras se caracterizaron mediante microscopía óptica y con el equipo analizador óptico de diámetro de fibra (OFDA 100). Se consideraron como variables independientes al diámetro de fibra, diámetro de médula, porcentaje de medulación por volumen, factor de confort, fibras objetables y como variable de respuesta al factor “Soft”. Esta última variable resultante de la diferencia del factor de confort y fibras objetables sirvió para darle un ordenamiento lógico a la matriz de datos y obtener un modelo de predicción preciso. Los valores promedio fueron 26.80±6.95 para el diámetro de fibra, 14.10±5.92 en diámetro de medula, 24.75±13.20 μm para el porcentaje de medulación por volumen y 71.56± 13.04% para el factor de confort. El modelamiento de regresión lineal múltiple de machine learning se adaptó con gran precisión a un tamaño muestral pequeño, mostrando errores mínimos, y optimizado con el algoritmo de gradiente descendiente estocástico predijo un factor Soft muy cercano al factor Soft observado. Se concluye que la técnica de regresión lineal múltiple con el enfoque estocástico satisface la predicción del nuevo factor denominado “soft” y que representa el modelamiento adecuado para la predicción de calidad de fibras en la industria textil.

Here, we have studied the impact of nanocrystalline cerium dioxide (NCD) particles on erythrocyte membrane state in a model of hypothermic storage of blood samples by examining the content of lipid peroxidation (LPO) primary products and hematological indices (free and total hemoglobin, hematocrit and hemolysis levels). After hypothermic storage of blood samples within 5 weeks, no significant difference in hematological indices between the control and experimental groups was revealed. In 2 weeks of hypothermic storage, the cells from experimental group in NCD presence showed an increased content of mainly those primary LPO products, which precursors were polyunsaturated fatty acids with two double bonds (conjugated dienes and oxidienes), thereby indicating the free radical processes activation. Four weeks’ storage demonstrated significantly decreased content of all primary LPO products in the experimental group cells in contrast to the control group. To the final step of the study (5 weeks of storage), the content of all primary LPO products in experimental and control groups was similar, that was an evidence of the ability of NCD particles to affect the erythrocyte membrane as well change the LPO intensity depending on storage period.

This article describes the effect of NF-κB inhibitor ammonium pyrrolidine dithiocarbamate and Nrf2 inducer dimethylfumarate on indicators of oxidative-nitrosative stress in skeletal muscles of rats with chronic hypomelatoninemia, induced by roundthe-clock illumination with an intensity of 1500 lux for 30 days, against the background of a carbohydrate-lipid diet (20% fructose solution and appropriate food) for 60 days. The study demonstrated that the administration of ammonium pyrrolidine dithiocarbamate and dimethylfumarate under the experimental conditions impedes the development of hypomelatoninemia, this was accompanied by a two-fold increase in the blood serum melatonin concentration compared to the control group. Moreover, the administration of ammonium pyrrolidine dithiocarbamate and dimethylfumarate significantly reduces the production of superoxide anion radical by electron transport chains of mitochondria (by 47.9 and 51.3%) and sarcoplasmic reticulum (by 48.6 and 52.0%) in the homogenate of femoral muscles, the total activity of NO synthase (by 37.2 and 36.2%) and its inducible isoform (by 41.1 and 40.0%), the concentration of peroxynitrites of alkaline and alkaline earth metals (by 37.2 and 41.0 %), while the activity of constitutive NO-synthases (by 2.9 and 2.8 times) and their conjugation index (by 5.2 and 5.4 times) increases compared to the respective control values. We suggest that modulators of redox-sensitive transcription factors NF-κB and Nrf2 under conditions of chronic hypomelatoninemia and the exposure to the carbohydrate-lipid diet are effective means to restrain the development of oxidative-nitrosative stress in skeletal muscles.

It is a known fact that Covid-19 has affected all academic activities including at the International Islamic University Malaysia (IIUM). There were many implications on students’ lives in terms of their academic affairs, mental health, finance, etc. In such a situation, tawakkul as coping mechanism plays a significant part, as it can define one’s capability in coping not only with the challenges due to Covid-19, but also with some tests from Allāh. This study analysed the perception of Hamka on Qur´ānic verses related to tawakkul. It also looked at how IIUM students dealt with challenges brought on by Covid-19. This study employed a qualitative research method in collecting data through semi-structured interviews and analysing them. The findings showed that tawakkul as coping mechanism according to Hamka refers to having strong imān in order to be able to overcome painful or difficult emotions. When tawakkul is considered as a coping mechanism, it appeared that it has a very considerable overlap and can be applied for the purpose of assisting one to live a better life. This is due to the fact that practising tawakkul as coping mechanisms will assist one in overcoming painful or difficult emotions. The findings also revealed that all of respondents believed that tawakkul was immensely helpful in coping with the challenges they faced during the COVID-19 pandemic.

Congenital malformations occur sporadically in cattle; however, congenital structural and functional disorders of the nervous system are rather common in ruminants. Among the numerous causes of congenital nervous system defects, infectious agents are highlighted in this paper. Virus-induced congenital malformations are well known, among which those caused by bovine viral diarrhoea virus (BVDV), Akabane virus (AKAV), Schmallenberg virus (SBV), Bluetongue virus (BTV), and Aino virus (AV) are the most studied. In this study, we specify and categorise macroscopic and histopathological lesions in the brain of 42 newborn calves suffering from severe neurologic signs and diagnosed with BVDV and AKAV infection. Following a complete necropsy, specimens were collected from the brains to track the presence of BVDV, AKAV and SBV utilising reverse transcription polymerase chain reaction. Of the 42 examined calves, 21 were BVDV positive and 6 were AKAV positive, while 15 brains were negative for the studied agents. Regardless of the aetiology, cerebellar hypoplasia, hydranencephaly, hydrocephalus, porencephaly, and microencephaly were detected. Cerebellar hypoplasia was the most common lesion seen in both BVDV-positive and AKAV-positive cases. Virus-induced necrosis of the germinative cells of the external granular layer of cerebellum, as well as vascular damages, are believed to be the underlying causes of cerebellar hypoplasia. BVDV was the most important aetiological agent of such cases in this study.

Authors: Fehér Krisztina , Takács Imre , Török Ákos
Published: April 2023

The paper deals with the material analysis of four emblematic stone fragments from Saint Adalbert Cathedral and the Royal Palace of Esztergom from King Béla III’s era. All of the four examined objects (two fragments from the Porta speciosa and two throne arm-rests) have incrustations with red limestone basement and other colourful stone pieces. As red limestone is a well-known material in Hungarian art history with a rich historiography, the paper focuses on the findings of the analyses of other stone materials of the incrustations. The research contains several non-destructive analytical methods, such as relative humidity measurement, macroscopic and microscopic photography and X-ray fluorescence with lithologic description. Besides the comparative analysis of the stone materials, archive documents, the current state and the impacts of subsequent restorations of the four stone artefacts were also studied.
Improving structural health monitoring with impact zone localization using heuristic algorithms

Published: April 2023

This paper presents a novel approach for reconstructing the characteristics of non-punctual impact events on elastic plates by introducing multi-parameter optimization. The objective function is minimized using two heuristic optimization techniques, particle swarm optimization, and differential evolution, to reconstruct impact force characteristics. The force was regarded as taking the form of a uniform pressure over a part of the plate called the patch. The Maxwell-Betti theorem was considered to decouple the problem of localization and the time history of the applying unknown load. The approach based on heuristic optimization methods has been proven a performance to locate the impact zone. A comparison between particle swarm optimization and differential evolution was discussed.

Aim of the study: The aim of the study was to determine the range and conditions for the formation of the piping hole and the piping canal found in the Pieniny National Park in May 2019. Material and methods: The scope of the research carried out included the determination of the geotechnical characteristics of subsoil on the slope near the piping hole and along the piping canal. Numerical calculations with the finite element method were also carried out in the GeoStudio program, which allowed to assess the possibilities of soil deformation caused by the seepage forces. Results and conclusions: The results of the research and the analysis of the literature showed that the piping processes in the Polish Carpathians are a common phenomenon that plays a sculptural role. The observed piping form indicates that on the slope is a continuous, several dozen meters long, piping channel formed in medium-cohesive, clay-dusty soils. It should be expected that during periods of prolonged or intense rainfall such phenomena will intensify. The calculation results did not confirm the occurrence of conditions favoring the formation of hydraulic deformations. However, during the increased filtration flow, high values of the hydraulic gradient in the soil are generated, which, in the case of high porosity of the soil, favors the removal of soil particles. The occurring process of piping on the slope in question is favored by the presence of a wooden through from which water infiltrates the ground, which increases the intensity of in-soil flow in the analyzed part of the slope.

Purpose. Establishing effective and correct techniques for detecting the grain structure in structural medium-carbon steels taking into account the recommendations of modern standards (ДСТУ ISO, ASTM, ГОСТ) with the aim of reliably determining the austenitic grain size and putting into operation of metal with the well-known and required, according to the normative technical documentation (technical requirements, drawings) quality.
Research methods. Metallographic analysis of microstructure and evaluation of the austenitic grain size were carried out by comparing the image revealed on polished and etched using various chemical reagents microsections of heat-treatable steel 40KHN2МА-Ш with etalon of scale of standard.
Results. Studies of structural alloyed steel 40ХН2МА-Ш found that the most effective etchant reagent, which best detects initial austenitic grain boundaries in medium-carbon alloyed steels, is a standard reagent - a saturated aqueous solution of picric acid. As a result of etching in this reagent, a visible image of the grain structure is formed in the form of a clear contrast of light areas of the grain body and dark lines of the grain boundaries, which allows a correct comparison of the structure with the images of the standards on the scales.
Scientific novelty. On the example of heat- treatable steel 40ХН2МА-Ш, the ways of further development of ideas regarding the choice of an effective chemical reagent are considered for the purpose of detecting and forming a visible grain structure in accordance with the requirements of methodical standards in structural medium-carbon steels, proper and reliable estimation of austenitіс grain size using standard scale.
Practical value. A correct procedure for detecting the initial austenite grain is proposed, which allows to reliably determine the grain size and quality from this parameter of various structural steels including for the production of responsible parts of aircraft and spacecraft.
