Utilization of Agricultural and Forestry by-Products in Ganoderma lucidum (Curt.: Fr.) P. Karst. Production
Authors: Atila Funda
Published: October 2024

The aim of the study was to evaluate the use of some local agricultural and forestry by-products as Ganoderma lucidum growing subsrate. In the study, 8 different growing media prepared by mixing agricultural and forestry wastes such as oak sawdust (OS), poplar sawdust (PS), wheat straw (WS), wood chips (WCH), green almond hulls (AH) and green walnut hulls (GWH) alone or in different proportions, were used for G. lucidum cultivation and the effects of these substrates on spawn run time (SRT), days to pinhead initiation (DPI), days to the first harvest (DFH), yield (g/kg) and biological efficiency (BE%) were investigated. The results demonstrated that spawn run time (SRT) of G. lucidum was shorter in PS and WS:GWH12.5 (19.7 days and 20.8 days) as compared to other substrates and mixtures (22.2-28.5 days). The pinheads emerged in substrates between 43th- 49th days and the fruiting bodies were collected between 80.3 -93.5 days after the spawning. Total fresh mushroom yield and BE(%) varied from 71.39 to 110.10 g/kg of substrate and from 21.0% to 31.46, respectively. Moreover, PS substrate produced fruitbody also earlier compared with the other investigated substrates. The study revealed that although higher total yields were obtained by sawdust substrates, considering the difficulty of finding sawdust in some areas, WS and the mixture of WS and GHW (87.5:12.5%) could be also successfully used inof G. lucidum production.

Green pea (Pisum sativum.) is an important consumable vegetable crop worldwide rich in protein, vitamins, and nutrition. It is cultivated in many parts of Iran, particularly during the summer season, and recently under protected greenhouse. Powdery mildew is an important disease of green pea, especially during the pod fill and maturation stage and decreases the photosynthetic area of leaves which causes crop loss. This experiment was conducted in order to identify fungi associated with powdery mildews on some accessions under regeneration of green pea collection at the genetic department and national plant gene bank of Iran, seed, and plant improvement institute during the year 2021. Powdery mildew became epidemic on the plants at the pod stage from the end of July to August. The formation of white, floury patches initially on the leaf progressing towards tendrils, pods, and stems observed that on susceptible accessions covered the most aerial part of the plants. The Erysiphe pisi, Erysiphe trifolii and Erysiphe baeumleri were reported causing disease on pea. The infected plant samples were collected and transferred to the lab for morphological studies, then, the genomic DNA was isolated and used for amplification and sequencing using the internal transcribed spacers (ITS) regions. Based on morphological characteristics of asexual and sexual stages as well as rDNA-ITS sequence analyses, the fungus was identified as Erysiphe pisi. Due to the presence of accessions with high levels of resistance to this disease, further investigation is recommended to breed resistant cultivars for cultivation in this province.

Published: October 2024

A species of Leguminosae family is Cajanus cajan (L.) Millsp. (Pigeon pea) is an herbaceous, annual, self-pollinated legume pulse crop. The pigeon pea is mainly cultivated in many countries of South Asia due to its nutritious quality and a good source of minerals and protein. Seeds are a common carrier of plant pathogens, which act as the primary source for the distribution of diseases. Contaminated seeds can often create defecated germination and poor seedling vigour. They lose viability much faster than non-contaminated seeds. A large number of mycoflora were reported to be associated with the pigeon pea seeds. To assess the seed health and quality of some pigeon pea accessions this experiment was conducted at the genetic department and national plant gene bank of Iran, seed, and plant improvement institute in 2021. In the experiment, a total of 52 accessions from the pigeon pea collection were used for laboratory tests. During this study different species of Alternaria spp., Aspergillus spp., Fusarium spp., Penicillium spp., and Rhizopus spp. were found along with germinating seed and seedlings of contaminated pigeon pea. The most identified species on the contaminated pigeon pea seeds were Rhizopus spp., with 50%, and the least were Alternaria spp. and Aspergillus spp., with 7.2%. The other species Penicillium spp., and Fusarium spp., were measured on 21.4% and 14.2% of the contaminated seeds respectively. On contaminated pigeon pea seeds, 20 to 100% reduction in seed germination has been measured. Paying attention to seed health is the fundamental strategy for the integrated management of the disease for durable crop production and seed conservation.

Kandidemi, Candida (C.) türü maya mantarları tarafından oluşturulan bir enfeksiyon hastalığıdır. Çoğunlukla hastanelerin yoğun bakım ünitelerinde ortaya çıkan erken tanısı ve tedavisi zor, mortalitesi yüksek önemli kan dolaşımı enfeksiyonlarındandır. Kandidemiye neden olan türlerin insidansı ülkeden ülkeye, hatta aynı ülkedeki hastaneler arasında değişebilmektedir. Kandidemi etkeni en sık Candida albicans (C. albicans)’dır. Ancak son yıllarda non-albicans Candida türleri ile gelişen kandidemi insidansında artış görülmeye başlanmıştır. Bu çalışmada Temmuz 2017- Temmuz 2022 tarihleri arasında Fırat Üniversitesi Tıp Fakültesi Mikrobiyoloji laboratuvarına yoğun bakım ünitelerinden kandidemi şüpheli hastalardan gönderilen kan örneklerinde saptanan Candida türlerinin dağılımı retrospektif olarak yapılmıştır. Laboratuvarımıza gelen kan kültür şişeleri BD BACTEC™ kan kültürü cihazına yerleştirilmiştir. 24 saat sonra pozitif sinyal veren kan kültür şişelerinden direk yapılan Gram boyamada Gram pozitif mantar sporları aranmıştır. Pozitif şişelerden %5 koyun kanlı agar besiyeri (Oxoid, İngiltere), eozin-metilen blue (EMB, Oxoid, İngiltere) ve Sabouraud Dektroz Agar (SDA, Oxoid, İngiltere) pasajları yapılmıştır. Kültürler bakteriyolojik olarak 18-24 saatlik, mikolojik olarak da 18-72 (bazen 1 hafta) saatlik 35-37°C’lik etüvdeki inkübasyonları sonunda üremeleri yönünden değerlendirilmiştir. Mikroorganizmaların tanımlanması; koloni yapıları, Gram boyama, germ tüp testi, konvansiyonel biyokimyasal test sonuçları ve matris destekli lazer desorpsiyon/iyonizasyon uçuş süresi kütle spektrometresi (MALDI-TOF MS) tekniğine dayalı olarak gerçekleştirilmiştir. Candida spp.yönünden pozitif 543 kan kültürünün 208’inde (%38) C. albicans, 335 (%62) ’inde non-albicans Candida türleri saptanmıştır. Non-albicans türlerden ise en sık 174 (%32) örnekte C. parapsilosis izole edilmişitir.
Kandidemi olgularından halen en sık izole edilen tür C. albicans’tır. Ancak yoğun bakım hastalarında non-albicans türleri de artan sıklıkla kan enfeksiyonlarına yol açmaya devam etmektedir.

Published: October 2024

Mantarlar, bakterilerle birlikte ekosistemin döngüsel olarak çalışmasını ve besin sirkülasyonunu sağlayan önemli ayrıştırıcılardır. Yenen mantarların toprak ve substrat üstü dokuları besin açısından zengindir ve insanlar tarafından çeşitli amaçlarla kullanılırlar. Özellikle substrat üzerinde çürükçül olarak yetişen mantarların kültüre alınıp yetiştirilmesi nispeten daha kolaydır.
Mantarların çoğu saprofit canlılardır. Özellikle besin kaynağı olarak kullandıkları bitki artıklarını (ağaç gövdesi, dal parçaları, yapraklar, ibreler, otlar, meyveler, kozalaklar vb.) parçalayarak beslenirler. Üzerinde yaşadıkları substratların bünyesinde bulunan makro ve mikro elementleri absorblayarak kendi bünyelerinde biriktirebilirler. Bu çalışmanın amaçlarından biri, yapılarında biriken minerallerin insan sağlığı açısından nasıl etki yapacağını tespit etmektir.
Çalışmamıza konu olan örnekler (Auricularia auricula-judae (Bull.) Quél., Lentinus arcularius (Batsch) Zmitr., Lentinus tigrinus (Boğa) Fr., Schizophyllum commune Fr., Trametes versicolor (L.) Lloyd, Tremella mesenterica (Schaeff.) Pers.) doğal ortamlarından toplanan beyaz çürükçül meydana getiren Basidiomycota bölümüne ait örneklerdir. Bu mantar örneklerinin ağır metal (Al, As, Cd, Co, Cu, Cr, Fe, Mg, Mn, Ni, Pb, Se ve Zn) iyon içerikleri ICP-OES (Inductively Coupled Plasma Optical Emission Spectrometry) spektrometresi kullanılarak belirlenmiştir.
Bu çalışmanın bir diğer amacı ise mantarların doğadaki önemli görevlerinden birini gerçekleştirmek için özellikle çevre temizleyici olarak hangi mantarlar kullanılabilir? sorusuna cevap aramaktır. Bu çalışmadan elde edilen veriler sayesinde mikoremediasyon yöntemleri geliştirilebilir. Mantarlar çok çeşitli kirleticileri kontamine ortamlardan veya atık sudan ayrıştırmak için ucuz, etkili ve çevreye duyarlı bir yöntem olarak kullanılabilir.
Sonuç olarak kullanılan mantar örnekleri için minimum ve maksimum ağır metal iyon konsantrasyonları tespit edilmiştir. İncelenen örneklerde Arsenik (As) hiç belirlenmemiştir. Nikel (Ni) ve Kurşun (Pb) bazı örneklerde eser miktarda gözlemlenmiştir. Selenyum (Se) ve Kobalt (Co) tüm örneklerde çok düşük seviyelerde ölçülmüştür. Magnezyum (772.1-2739 mg/kg), Demir (49.91-1583 mg/kg) ve Alüminyum (8.009-1298 mg/kg) mineralleri araştırmada kullanılan tüm örneklerde en yüksek oranlarda tespit edilen ağır metal iyonlarıdır.

Published: October 2024

Potato downy mildew is a disease caused by a fungus called Phytophthora infestans (Mont.) de Bary, which is mainly seen in potatoes and tomatoes, but also in other culture and wild plants belonging to the Solanaceae family. This fungus is quite important both from an economic and historical point of view. In case of an epidemic, it can cause full crop deterioration or serious losses in potatoes. Although cultural and chemical control methods are generally used in the control of the disease, there is no specific biological control method in this regard. Entomopathogenic fungi (EPFs) are generally used as biological control agents in the control of insect pests. Recently, there are many studies showed that these fungi can live endophytically on various cultivated plants and provide beneficial properties to the plants they live with. In this study, it was aimed to determine the in vitro antagonistic activities of different entomopathogenic fungi previously isolated from potato fields and identified by molecular methods against P. infestans. Earlier work determined that these fungi had a lethal effect on Leptinotarsa decemlineata (Say, 1824). Antagonistic activity tests were performed according to the "direct opposition method" and percentage (%) activity values were calculated. As a result of the tests, the most effective isolates were found to be Beauveria sp. SK-14 (75.23%) and Metarhizium sp. SK-24 (76.23%). It is thought that the results obtained will contribute to the biocontrol of diseases and pests in potatoes.

Published: October 2024

The aim of this study is to determine the factors that impact MSMEs' sustainability practices and the degree to which they concentrate on business sustainability in Indonesia. This study used a quantitative research approach and collected survey data from MSMEs in Indonesia operating in various industries totaling 350 samples. Partial Least Squares Structural Equation Modeling (PLS-SEM) was used for data analysis to assess the relationship between variables. The study discovered that a focus on the environment, the application of technology, and green marketing greatly improve an organization's capacity for innovation, which in turn has a favorable impact on the sustainability of the firm. MSMEs are more likely to develop and maintain their business practices over time if they invest in green marketing techniques, use cutting-edge technologies, and give priority to environmental issues. In order to attain sustainability, MSMEs should include technology, marketing, and environmental initiatives into their fundamental business operations, according to the research. It is recommended that policymakers provide incentives, subsidies, and training programs to MSMEs in order to encourage the adoption of technology and green marketing. Support like this can encourage sustainable practices throughout the industry and close the digital divide. This study offers insightful information about the combined effects of environmental orientation, technology adoption, and green marketing on MSMEs in Indonesia's capacity for innovation and long-term viability of their businesses. It gives helpful suggestions for boosting MSMEs' sustainability and emphasizes the crucial role that innovation plays in converting these elements into sustainable business practices.

With the advancements in technology, the deployment of air defence systems required for the defence of a country after procurement is considered as an important problem in terms of defence effectiveness. It is seen that criteria such as coverage, strike effectiveness and logistics network are taken into account while deploying. In addition, principles such as remote countermeasures, defence in depth and all-round defence are also taken into account. In this study, two different deployment models are proposed for point and area air defence. In this model, the optimum deployment distance at which other systems can support each other in addition to a deployed air defence system is determined. In the nonlinear target programming model proposed for point air defence, the number of missiles is considered to be reasonably balanced for perimeter defence, while for area defence, the nonlinear optimization problem is addressed by calculating the equally important coverage and strike effectiveness criteria values. In this study, it is observed that the approach based on mutual support distance has been used for the first time in the defence literature.

Due to the increasing complexity of educational data, the use of decision analysis techniques such as Multi-Criteria Decision Making (MCDM) models has become more popular in the education system in recent years. Multi criteria decision making methods provide data analysis methods faster and more efficient for revealing unhidden patterns and other meaningful information from vast educational data those conventional analytics are unable to discover in a reasonable amount of time. Particularly, MCDM techniques have been demonstrated to be effective methods for pattern recognition in educational systems. Motivated by this consideration, the purpose of this paper is to investigate the MCDM approaches applied to education systems through a review of new architectures, applications, and educational trends. The primary objective of this paper is to provide extensive insight into the application of MCDM models to education solutions in order to bridge the gap between MCDM techniques and human-based education interpretability. Then, the application of MCDM to various aspects of education are categorized. Finally, we present the current open challenges and future directions.

The spring-in and spring-back behavior of polymers is intricate and influenced by various process parameters and mechanisms, including interply slip, anisotropic thermal expansion, and crystallization, all of which can lead to residual stresses. Composite materials made of metal and polymer are being investigated by researchers as a promising alternative to monometallic materials due to their superior properties. However, the number of studies related to metal/polymer/metal laminates on the same topics is relatively limited. A comprehensive review study was carried out with a focus on research works that were conducted with the consideration of different process parameters, such as radius of die and punch, friction, and force applied by blank holder, in order to observe their impact on the springback behavior of polymers. Springback on polymer components depends on the accuracy of appropriate materials and the consideration of appropriate experimental strategies. However, due to their viscoelastic properties, polymers demonstrate distinctive springback behavior. Furthermore, when subjected to deformation, polymers experience a combination of elastic and viscous responses, resulting in immediate elastic recovery and time-dependent viscoelastic relaxation. This intricate behavior presents difficulties in precisely forecasting and managing springback. To enhance the control and optimization of springback in polymer-based manufacturing processes, it is essential to improve the understanding of polymer behavior under diverse loading conditions and to refine simulation techniques accordingly. This review focuses on springback prediction models specific to polymers.
Birds of a Feather Do Flock Together: Behavior-Based Personality-Assessment Method Reveals Personality Similarity Among Couples and Friends

Published: October 2024

Friends and spouses tend to be similar in a broad range of characteristics, such as age, educational level, race, religion, attitudes, and general intelligence. Surprisingly, little evidence has been found for similarity in personality—one of the most fundamental psychological constructs. We argue that the lack of evidence for personality similarity stems from the tendency of individuals to make personality judgments relative to a salient comparison group, rather than in absolute terms (i.e., the reference-group effect), when responding to the self-report and peer-report questionnaires commonly used in personality research. We employed two behavior-based personality measures to circumvent the reference group effect. The results based on large samples provide evidence for personality similarity between romantic partners (n = 1,101; rs = .20–.47) and between friends (n = 46,483; rs = .12–.31). We discuss the practical and methodological implications of the findings.
Increasing response vigour under time pressure as a transdiagnostic marker of eating disorders
Authors: Hall-McMaster Sam , Zika Ondrej
Published: October 2024

Eating disorders (EDs) are characterised by extreme concerns about food and weight. These concerns are linked to changes in decision-making, such as persisting with actions that are no longer rewarding. This study tested whether people with eating disorder symptoms show increased persistence due to altered decision thresholds for behavioural adaptation. A group with heightened concerns about eating (ED; N=48) and a healthy control group (HC; N=56) completed a foraging task, in which an option on screen was exploited for reward. With each decision to exploit, reward feedback decreased and participants had to decide when to move on to a new option. Each block was time limited to 7.5 minutes. Behavioural persistence was measured as the number of seconds spent exploiting each option. Decision thresholds were measured when deciding to move on, as the counterfactual reward that would have been received for an exploit action. We predicted that the ED group would show increased persistence and decreased decision thresholds (i.e. lower counterfactual reward when deciding to move on). We found no evidence for these predictions. Instead, exploratory analyses showed that the ED group exhibited progressively faster response times (RTs) when approaching the time limit for each block. This increase in motor vigour correlated with the severity of eating disorder symptoms and total rewards earned. Our results point to changing motor vigour as a potential transdiagnostic marker of ED tendencies.
Accelerated experimental method of detection the functional dependence between the starting torque of an induction motor and the stator voltage
Authors:   Vinnytsia National Agrarian University, Hraniak V. F.
Published: October 2024

The features of obtaining the experimental dependence of the starting torque of an induction motor on the supply voltage of the stator have been studied. It is shown that when determining this dependence, the motor operates in short-circuit mode, which leads to rapid overheating of its windings. An accelerated experimental method for determining the functional dependence of the starting torque on the supply voltage has been proposed and justified. This approach allows for a complete series of measurements of the starting torque at different values of stator circuit voltage within a time frame that does not exceed the heating period of the windings from the initial to the rated temperature. A design for the experimental setup has been developed. Mathematical models describing the thermal behavior of the stator windings and the mechanical movement of the analog part of the starting torque measurement channel have been developed, confirming the validity of the proposed method for determining the functional dependence of the starting torque of an induction motor on the stator circuit voltage.
Analysis of the influence of individual characteristics of LiFePO4 cells on the performance parameters of battery assemblies

Published: October 2024

The article analyzes the influence of the individual characteristics of lithium-iron-phosphate (LiFePO4) cells on the overall efficiency, stability and duration of operation of battery assemblies. The influence of such parameters as internal resistance, polarization resistance and capacity on the operation of battery assemblies under different load regimes and changes in temperature conditions was studied. It was found that these parameters can vary significantly between cells within the same assembly, which leads to an imbalance during the operation of the battery system. Such an imbalance causes an uneven distribution of charge between the cells, which reduces the overall performance of the system, accelerates the degradation of the cells and shortens their service life. To overcome these problems, the use of active balancing methods based on Unscented Kalman Filter (UKF) algorithms was proposed. The application of UKF allows for dynamic evaluation of the state of charge (SOC) of each cell and adjustment of system parameters in real time, which provides more accurate management of battery assemblies in conditions of variable external factors such as temperature and current loads. Special attention is paid to online identification of battery parameters, such as polarization resistance and capacity, which change over time due to cell aging. The conducted studies confirmed that constant monitoring of temperature regimes is critically important for maintaining stable operation of battery cells, preventing overheating and ensuring uniform load distribution. The performed simulation confirmed the effectiveness of the application of adaptive methods of balancing and temperature control, which allows to increase the reliability and overall performance of battery assemblies.

The article considers the improvement of the control with using the generation of renewable energy sources forecast for a grid-connected a hybrid power supply system of a livestock farm with electric transport and a gas generator. The task is to form a graph of the state of charge of the main battery with a limitation of the depth of discharge with the maximum use of renewable sources energy. The calculation method of the state of charge of a battery and power consumption graph when working with the grid and in autonomous mode has been improved, with the definition of recommendations for charging electric transport. A mechanism has been developed for correcting the power consumption based on the deviation of the battery charge state relative to the specified value, with the correction disabled to implement the function of eliminating the export of excess energy to the grid or gas generator. This ensures the limitation of the gas generator power within certain limits and helps to limit the influence of generation and load deviations relative to the forecast on the battery discharge depth. The structure of the energy processes model in the system for the daily operation cycle has been developed. In the process of modeling, the deviation of renewable energy generation up to 20% and 10% was studied simultane-ously with a 10% increase in load.

Annotation. Studying the deformations of palladium membranes under the influence of hydrogen, which is a relevant issue for hydrogen energy and the nuclear industry. The mechanisms of palladium membrane shape change due to hydrogen penetration and the formation of temporary gradient alloys such as α-PdHn are consid-ered. Experiments were conducted using a hydrogen-vacuum installation, where the processes of membrane satu-ration and degassing were studied at temperatures from 100°C to 360°C and hydrogen pressures from 0.01 MPa to 2.5 MPa. It was established that the change in the shape of the membrane occurs in two stages: first, a rapid bending of the membrane is observed, and then a gradual return to the initial state. It was established that the maximum change in the shape of the membrane, which occurs at a constant temperature, depends on the diffu-sion coefficient and the equilibrium solubility of hydrogen in palladium. However, when the temperature chang-es, the diffusion coefficient of hydrogen in palladium and the equilibrium concentration of hydrogen in palladi-um also change, which affects the temperature dependence of the final shape change of the membrane. This fact makes it possible to effectively determine the time of hydrogen penetration into the membrane, control the change in shape and adjust the operating modes of the fuel cell. Special attention is paid to the use of palladium alloys with copper and silver to increase the resistance of membranes to the influence of hydrogen. It is shown that such alloys have better mechanical characteristics and a longer service life at high temperatures. The effect of degassing on the restoration of membranes after contact with hydrogen was studied, the main factors affecting the efficiency of this process were determined. The results of the work confirm the need for further research on increasing the resistance of palladium membranes to deformations, as well as the development of new materials and technologies to improve their operational characteristics
