Galaxolide-contaminated soil and tolerance strategies in soybean plants using biofertilization and selenium nanoparticle supplementation
Authors: Halawani Riyadh F. , Aloufi Fahed A.
Published: August 2023

The current study aimed to address the response of soybean (Glycine max) plants to biofertilization and selenium supplementation treatments under galaxolide contamination of soil. In this regard, a pot experiment was carried out where the soybean plants were treated with the plant growth-promoting Actinobacteria (Actinobacterium sp.) as a biofertilizer (PGPB treatment) and/or selenium nanoparticles (Se treatment; 25 mg L-1) under two non-polluted and galaxolide-polluted soils (250 mg galaxolide per kg of soil) to assess the modifications in some plant physiological and biochemical traits. Although higher accumulation of oxidative biomarkers, including hydrogen peroxide (+180%), malondialdehyde (+163%), and protein oxidation (+125%), indicating oxidative stress in galaxolide-contaminated plants, an apparent decline in their contents was observed in response to biofertilization/supplementation treatments in contaminated soil, especially. It was mainly related to the higher detoxification of ROS in PGPB- and Se-treated plants under galaxolide-induced oxidative stress, in which the direct ROS-scavenging enzymes (+44 -179%), enzymatic (+34 - 293%) and non-enzymatic (+35 - 98%) components of the ascorbate-glutathione pathway, and antioxidant molecules (+38 - 370%) were more activated than in control plants. In addition, a higher accumulation of detoxification activity markers, including phytochelatins (+32%) and metallothioneins (+79%), were found in the combined treatments (PGPB+Se) under galaxolide contamination. Moreover, combined treatment with PGPB and Se ameliorated the levels of chlorophyll a content (+58%), stomatal conductance (+57%), the maximum efficiency of photosystem II (PSII) (+36%), and photorespiratory metabolism (including +99% in glycolate oxidase and +54% in hydroxypyruvate reductase activity) in leaves under galaxolide contamination, which resulted in higher photosynthesis capacity (+36%) and biomass production (+74%) in galaxolide-stressed plants as compared to control group. In conclusion, the application of beneficial Actinobacteria and selenium nanoparticles as biofertilization/supplementation is expected to be useful for improving plant toleration and adaptation against galaxolide contamination.
A hypervariable intron of the STAYGREEN locus provides excellent discrimination among Pisum fulvum accessions and reveals evidence for a relatively recent hybridization event with Pisum sativum

Published: August 2023

An analysis of 82 non-synonymous Pisum fulvum accessions for sequence variation in a fragment of the STAYGREEN (SGR) locus revealed 57 alleles, most of which differed in indel structure. Eight additional P. fulvum accessions, each supposedly synonymous with a different accession of the initial group, were also analyzed. In every case the paired synonymous accessions possessed the same SGR sequence but varied slightly for a 6-trait morphological phenotype, indicating that SGR sequence is a much more reliable indicator of accession identity than is a morphological characterization. SGR sequence analysis confirmed our previous finding that P. fulvum accessions separate into two allele groups. This division was not supported by results of previous studies that were based on sequences distributed across the entire genome, suggesting that the division may have been produced by selection at a nearby locus and that the SGR phylogeny may not be good indicator of overall relationships within the species. One P. fulvum accession, PI 595941 (=JI1796), displayed an SGR sequence outside the variation typical of the species. Instead, its allele resembled alleles limited to a set of Pisum sativum landraces from the Middle East, suggesting hybridization between ancestors of PI 595941 and some primitive form of domesticated P. sativum. With one exception from the extreme northwest corner of Israel, P. fulvum accessions collected north of latitude 35.5° N were fixed for alleles from group A. These northern accessions also displayed greatly reduced SGR sequence diversity compared to group A accessions collected from other regions, suggesting that the northern populations may represent recent extensions of the range of the species. Group B accessions were distributed from Lake Tiberias south and were generally sympatric with the southern group A accessions. Although group B accessions occupied a smaller area than group A, the SGR sequence diversity in this group (28 alleles in 33 accessions) exceeded that for group A.
Error orientation in a decision-making simulation program: differences between promotion vs. prevention focus
Authors: Arenas Alicia , Briones Elena , Tabernero Carmen
Published: August 2023

Changing situations develop work environments where workers must generate strategies to learn and persist from continuous errors and setbacks. Previous research has shown that errors enhance motivation, break the routine, lead to creative solutions, and reduce frustration; however, this positive aspect seems to have a stronger presence if personal factors and contextual background support such a focus. The main aim of this paper was to analyse, with an experimental design, how different frames about errors and negative feedback (error promotion versus error prevention) affected performance and decision-making processes in a complex simulation task, taking into account individual attitude towards errors. The sample included 40 employees of a Spanish transportation company (37.5% were women and 62.5% were men). Firstly, participants answered a questionnaire about their individual Error Orientation. Then, they were randomly assigned to an experimental condition to carry out a complex decision-making task through a multimedia simulator, which aimed to expose the participant to factors that influence the dynamics of innovation and change, elements that are present in all modern organizations. None of the participants had previous experience in the task. Performance was measured through different aspects: (1) final performance values: adopters, points, time to make decisions and time after receiving negative feedback; (2) the decision-making process. Results showed that error orientation is related to final performance, especially error risk taking and error communication. The effect of the experimental condition was higher for the time to make decisions after receiving negative feedback and for the time to complete the simulation program. Those who worked under the error prevention condition took significantly longer to perform the task. Although our results show non-consistent effects, which frame than the other (promotion versus prevention) is better to make decisions is discussed. A promotion frame prioritizes flexibility, openness, and rapid progress, but does so by sacrificing certainty, and careful analysis. The most crucial factor may be which one best fits the demands of the task at hand.
Relational memory weakness in autism despite the use of a controlled encoding task
Authors: Minor Greta N. , Hannula Deborah E. , Gordon Andrew , Ragland J. Daniel , Iosif Ana-Maria , Solomon Marjorie
Published: August 2023

Introduction

Recent work challenged past findings that documented relational memory impairments in autism. Previous studies often relied solely on explicit behavioral responses to assess relational memory integrity, but successful performance on behavioral tasks may rely on other cognitive abilities (e.g., executive functioning) that are impacted in some autistic individuals. Eye-tracking tasks do not require explicit behavioral responses, and, further, eye movements provide an indirect measure of memory. The current study examined whether memory-specific viewing patterns toward scenes differ between autistic and non-autistic individuals.

Methods

Using a long-term memory paradigm that equated for complexity between item and relational memory tasks, participants studied a series of scenes. Following the initial study phase, scenes were re-presented, accompanied by an orienting question that directed participants to attend to either features of an item (i.e., in the item condition) or spatial relationships between items (i.e., in the relational condition) that might be subsequently modified during test. At test, participants viewed scenes that were unchanged (i.e., repeated from study), scenes that underwent an “item” modification (an exemplar switch) or a “relational” modification (a location switch), and scenes that had not been presented before. Eye movements were recorded throughout.

Results

During study, there were no significant group differences in viewing directed to regions of scenes that might be manipulated at test, suggesting comparable processing of scene details during encoding. However, there was a group difference in explicit recognition accuracy for scenes that underwent a relational change. Marginal group differences in the expression of memory-based viewing effects during test for relational scenes were consistent with this behavioral outcome, particularly when analyses were limited to scenes recognized correctly with high confidence. Group differences were also evident in correlational analyses that examined the association between study phase viewing and recognition accuracy and between performance on the Picture Sequence Memory Test and recognition accuracy.

Discussion

Together, our findings suggest differences in the integrity of relational memory representations and/or in the relationships between subcomponents of memory in autism.

Published: August 2023

Introduction

The symptoms of major depressive disorder (MDD) vary widely. Psycho-neuro-inflammation has shown that MDD’s inflammatory factors can accelerate or slow disease progression. This network analysis study examined the complex interactions between depressed symptoms and inflammatory factors in MDD prevention and treatment.

Measures

We gathered participants’ inflammatory factor levels, used the Hamilton Depression Scale (HAMD-17), and network analysis was used to analyzed the data. Network analysis revealed the core inflammatory (nodes) and their interactions (edges). Stability and accuracy tests assessed these centrality measures’ network robustness. Cluster analysis was used to group persons with similar dimension depressive symptoms and examine their networks.

Results

Interleukin-1β (IL-1β) is the core inflammatory factor in the overall sample, and IL-1β—interleukin-4 (IL-4) is the strongest correlation. Network precision and stability passed. Network analysis showed significant differences between Cluster 1 (with more severe anxiety/somatization and sleep disruption) and Cluster 3 (with more severe retardation and cognitive disorders), as well as between Cluster 2 (with more severe anxiety/somatization, sleep disruption and body weight) and Cluster 3. IL-1β is the core inflammatory factor in Cluster 1 and Cluster 2, while tumor necrosis factor alpha (TNF-α) in Cluster 3.

Conclusion

IL-1β is the central inflammatory factor in the network, and there is heterogeneity in the core inflammatory factor of MDD with specific depressive dimension symptoms as the main manifestation. In conclusion, inflammatory factors and their links should be prioritized in future theoretical models of MDD and may provide new research targets for MDD intervention and treatment.
Vascular-related biomarkers in psychosis: a systematic review and meta-analysis
Authors: Li Xiaojun , Hu Shuang , Liu Pozi
Published: August 2023

Background

While the molecular underpinnings of vascular dysfunction in psychosis are under active investigation, their implications remain unclear due to inconsistent and sometimes sparse observations. We conducted a comprehensive meta-analysis to critically assess the alterations of vascular-related molecules in the cerebrospinal fluid (CSF) and blood of patients with psychotic disorders compared with healthy individuals.

Methods

Databases were searched from inception to February 23, 2023. Meta-analyses were performed using a random-effects model. Meta-regression and subgroup analyses were conducted to assess the effects of clinical correlates.

Results

We identified 93 eligible studies with 30 biomarkers investigated in the CSF and/or blood. Among the biomarkers examined, psychotic disorders were associated with elevated CSF-to-serum albumin ratio (standardized mean difference [SMD], 0.69; 95% confidence interval [CI], 0.35–1.02); blood S100B (SMD, 0.88; 95% CI, 0.59–1.17), matrix metalloproteinase-9 (MMP-9; SMD, 0.66; 95% CI, 0.46–0.86), and zonulin (SMD, 1.17; 95% CI, 0.04–2.30). The blood levels of S100B, MMP-9, nerve growth factor (NGF), vascular endothelial growth factor (VEGF), intercellular adhesion molecule 1 (ICAM-1), and vascular adhesion molecule 1 (VCAM-1) were altered in patient subgroups differing in demographic and clinical characteristics. Blood S100B level was positively correlated with age and duration of illness. Substantial between-study heterogeneity was observed in most molecules.

Conclusion

The alterations in certain vascular-related fluid markers in psychotic disorders suggest disturbances in normal vascular structures and functions. However, not all molecules examined displayed clear evidence of changes. While potential impacts of clinical factors, including the administered treatment, were identified, the exploration remained limited. Further studies are needed to investigate the diverse patterns of expression, and understand how these abnormalities reflect the pathophysiology of psychosis and the impact of clinical factors.
Psychology, stress, insomnia, and resilience of medical staff in China during the COVID-19 policy opening: a cross-sectional survey
Authors: Cheng Zhen , Tao Yuanling , Liu Ting , He Siyue , Chen Yu , Sun Li , Chen Zongtao
Published: August 2023

Background

Since 8 January 2023 China has liberalized its control of COVID-19. In a short period of time, the infection rate of COVID-19 in China has risen rapidly, which has brought a heavy burden to medical staff. This study aimed to investigate the psychological status, stress, insomnia, effort-reward imbalance, resilience, and influencing factors of medical staff in China during the period of epidemic policy liberalization.

Methods

This survey was conducted from 6 February to 27 March 2023 with non-random sampling. An online questionnaire survey was conducted using HADS, PSS-14, ISI, ERI, and the resilience assessment scale for medical staff. The levels of psychological, stress, insomnia, effort-reward imbalance, and resilience of medical staff during the pandemic policy opening period were measured.

Results

A total of 2,038 valid questionnaires were collected. 68.5% and 53.9% of medical staff had different degrees of anxiety and depression, respectively. Excessive stress, insomnia, and high effort and low reward were 40.2%, 43.2%, and 14.2%, respectively. Gender, Profession, education level, and age are important factors that lead to anxiety and depression. Women, nurses, higher education, longer working years and hours, high effort, and low reward are risk factors for the above conditions. There was a certain correlation among the five scales, among which anxiety, depression, stress, insomnia, effort-reward imbalance, and other factors were positively correlated, while resilience was negatively correlated with these factors.

Conclusion

This study found that anxiety, depression, stress, insomnia, and other psychological problems of medical staff in China during the policy opening period of COVID-19 were more serious than before. At the individual and organizational levels, it is necessary to improve the well-being of medical staff, optimize the allocation of human resources, and promote the mental health of medical staff with a focus on prevention and mitigation, with the entry point of improving resilience and preventing the effort-reward imbalance.
Assessment of knee flexion in young children with prosthetic knee components using dynamic time warping
Authors: Geil Mark D. , Safaeepour Zahra
Published: August 2023

Introduction

Analysis of human locomotion is challenged by limitations in traditional numerical and statistical methods as applied to continuous time-series data. This challenge particularly affects understanding of how close limb prostheses are to mimicking anatomical motion. This study was the first to apply a technique called Dynamic Time Warping to measure the biomimesis of prosthetic knee motion in young children and addressed the following research questions: Is a combined dynamic time warping/root mean square analysis feasible for analyzing pediatric lower limb kinematics? When provided at an earlier age than traditional protocols dictate, can children with limb loss utilize an articulating prosthetic knee in a biomimetic manner?

Methods

Warp costs and amplitude differences were generated for knee flexion curves in a sample of ten children five years of age and younger: five with unilateral limb loss and five age-matched typically developing children. Separate comparisons were made for stance phase flexion and swing phase flexion via two-way ANOVAs between bilateral limbs in both groups, and between prosthetic knee vs. dominant anatomical knee in age-matched pairs between groups. Greater warp costs indicated greater temporal dissimilarities, and a follow-up root mean square assessed remaining amplitude dissimilarities. Bilateral results were assessed by age using linear regression.

Results

The technique was successfully applied in this population. Young children with limb loss used a prosthetic knee biomimetically in both stance and swing, with mean warp costs of 12.7 and 3.3, respectively. In the typically developing group, knee motion became more symmetrical with age, but there was no correlation in the limb loss group. In all comparisons, warp costs were significantly greater for stance phase than swing phase. Analyses were limited by the small sample size.

Discussion

This study has established that dynamic time warping with root mean square analysis can be used to compare the entirety of time-series curves generated in gait analysis. The study also provided clinically relevant insights on the development of mature knee flexion patterns during typical development, and the role of a pediatric prosthetic knee.

Introduction

[18F]FDG PET/CT noninvasively disproves acute kidney allograft rejection (AR) in kidney transplant recipients (KTRs) with suspected AR. However, the correlation of biopsy-based Banff vs. PET/CT-based scores of acute inflammation remains unknown, as does the prognostic performance of [18F]FDG PET/CT at one year post suspected AR.

Methods

From 2012 to 2019, 114 [18F]FDG-PET/CTs were prospectively performed in 105 adult KTRs who underwent per cause transplant biopsies. Ordinal logistic regression assessed the correlation between the extent of histological inflammation and the mean standardized [18F]FDG uptake values (mSUVmean). Functional outcomes of kidney allografts were evaluated at one year post per cause biopsy and correlated to mSUVmean.

Results

A significant correlation between mSUVmean and acute Banff score was found, with an adjusted R2 of 0.25. The mSUVmean was significantly different between subgroups of “total i”, with 2.30 ± 0.71 in score 3 vs. 1.68 ± 0.24 in score 0. Neither the function nor the survival of the graft at one year was statistically related to mSUVmean.

Discussion

[18F]FDG-PET/CT may help noninvasively assess the severity of kidney allograft inflammation in KTRs with suspected AR, but it does not predict graft outcomes at one year.
What Happens in Your Brain When You Spot Something Scary?
Authors: Zsido Andras N. , Hout Michael C.
Published: August 2023

Have you ever noticed that you are good at spotting things in your environment that are potentially dangerous—like a spider crawling on the wall? The brain systems that cause us to notice threatening things are so fundamental that most people are not even aware of them. Brain systems called defensive circuits are tuned to detect threats in our daily lives. These circuits help us to notice the specific features of threatening objects, like the curvy shape of a snake, and they prepare the body to take quick action, like fighting back or running away, therefore increasing our chances of survival. However, sometimes these circuits are overly sensitive, and they sound the alarm too often. These “false alarms” can cause us to see threats in places where there are none. Understanding how threat detection works may help us to understand—and maybe even overcome—our fears!
Prediction of Microwave Characteristic Parameters Based on MMIC Gold Wire Bonding
Authors: Yu Shenglin , Li Hao
Published: August 2023

In this paper, a method based on deep learning is proposed to predict the parameters of bonded metal wires, which solves the problem that the transmission characteristics of S-parameters cannot be predicted. In an X-band microwave chip circuit, gold wire bonding technology is often used to realize bonding interconnection, and the arch height and span of the bonded metal wire will have a great influence on the microwave transmission characteristics. By predicting the S-parameters of the bonded metal wire, the relationship between the structure parameters of the single wire and the transmission performance of the microwave device can be deduced. First, the gold wire bonding model is established in HFSS simulation software. After parameter optimization, the simulation results meet the requirements of establishing data sets. Then the sampling range of S parameters is set, and the parameters are scanned to establish data sets. Second, the artificial neural network model is built. The model adds a dropout mechanism to the hidden layer to enhance the generalization of the neural network, prevent overfitting phenomenon, and significantly improve the model’s prediction performance. Finally, the model predicts the corresponding relationship between the arch height and span of the bonding wire and the insertion loss, return loss and standing wave ratio. The mean square error of the test set is less than 0.8. The experimental results show that compared with the traditional process measurement method, this method can quickly and accurately infer whether the microwave characteristics of the bonded product are qualified, which greatly reduces the time and economic cost of the engineer and improves the work efficiency.
The Interaction of Talc, Montmorillonite, and Silica Sand with H2O Influences Methane Hydrate Formation
Authors: Huang Ruifang , Zhao Yusheng , Ma Yiming
Published: August 2023

Methane hydrates in natural geological settings are commonly distributed within sediments, with a variety of minerals (such as silica sand, talc, and montmorillonite). The mechanisms that control the influence of sediments on methane hydrate formation remain poorly understood. In this study, we performed experiments on methane hydrate formation in pure H2O with the addition of 3% sediments (montmorillonite, talc, and silica sand). A large-volume stirred reactor (80 mL) and a small-volume unstirred reactor (20 mL) were used. The results show that montmorillonite and talc severely inhibit methane hydrate formation. For experiments in the stirred reactor with pure H2O, normalized gas consumption is 30 (mmol/mol) after 1000 min. In contrast, normalized gas consumption in experiments with the addition of 3% montmorillonite and talc decreases greatly to <5 (mmol/mol) over the same period. The inhibiting effect of montmorillonite and talc is closely associated with the release of cations (Mg2+, Ca2+, K+, and Na+) into fluids, with higher concentrations of cations for slower rates of methane hydrate formation. The interaction of montmorillonite and talc with H2O consumes hydrogen ions (H+), resulting in alkaline solutions. It was found that alkaline solutions may not be favorable for methane hydrate formation. In contrast, silica sand slightly promotes methane hydrate formation in the unstirred reactor, which may be related to acidic solutions formed during the interaction of silica sand with H2O. The phase equilibrium temperatures and pressures of methane hydrate in the presence of 3% montmorillonite, talc, and silica sand are essentially the same as those in pure H2O, excluding the thermodynamic effect of minerals. The experiments of this study are important for understanding the formation of massive methane hydrates with low amounts of sediment (e.g., ≤3%). They suggest that methane hydrates may not be highly concentrated in sediments with abundant talc and montmorillonite. The experiments of this study may explain the close association of methane hydrates with silica sand.
Enhanced Assembling of N-and-K-Riched Macroalgae as Carbon Adsorbent for CO2 Capture with Ni(NO3)2/KOH as Co-Catalysts

Published: August 2023

Porous-activated carbons have drawn great attention due to their important role in CO2 capture. Ni(NO3)2/KOH, as co-catalysts under different temperatures, were studied to obtain porous graphitized carbon from Sargassum horneri feedstock. The results indicated that the properties of the porous graphitized carbon generated at 850 °C were greatly enhanced, showing a large specific surface area of 1486.38 cm3·g−1 with narrowly distributed micropores (~0.67 nm) and abundant functional groups, which endowed high CO2 uptake; moreover, the high CO2 uptake was mainly attributed to the synergistic effect of Ni(NO3)2 and KOH, both in chemical modification and pore formation. The fitted values of the four kinetic models showed that the double exponential model provided the best description of carbon adsorption, indicating both physical and chemical adsorption. It is worth noting that carbon could be reused four times in the adsorption/desorption procedure in this research with good stability. This work focuses on the high-value-added comprehensive utilization of macroalgae, which not only is important for high-performance adsorbent preparation but also has positive benefits for the development and utilization of macroalgae resources.
Between the Boundaries of Asceticism and Activism: Understanding the Authority of the Sadhvis within the Hindu Right in India
Authors: Dasgupta Koushiki
Published: August 2023

Given the emergence of the Ram Janmabhoomi Movement in the early 1990s, a group of female ascetics and sadhvis displayed tendencies of eschewing conventional gendered images and reinforcing the ideals of virtuous motherhood and female warriorhood in an effort to establish women’s alternative authority in the public and private domains. In order to galvanise women’s participation in the public sphere, these sadhvis allowed women to assume roles that would otherwise be reserved for men on the grounds that men are no longer living according to their dharma. In reality, the sadhvis were reorganising the feminine space within a predominately masculine Hindutva movement by recommending a level of politicisation of women’s private responsibilities in the public sphere with a distinctive articulation of particular gender stereotypes. Taking into account these factors, my aim in writing this essay is to examine the ramifications of the agency and authority that these sadhvis achieved while actively participating in the Hindutva movement. This paper also aims to find out which types of approaches they employed to address the conflicts between conventional womanhood, asceticism, and heroic femininity in the arena of public life.

Published: August 2023

The COVID-19 pandemic precipitated an unprecedented paradigm shift in higher education, compelling swift adaptation to online teaching methods. Consequently, the merits of remote education, including increased flexibility and geographic independence, were emphasized. At the same time, however, the problems associated with distance education became apparent, such as the lack of networking, collaborative learning, and social interactions. This situation led to detrimental effects on student motivation and learning outcomes in team-oriented software engineering courses.To address the dichotomy of learning preferences, one potential solution proposed is the simultaneous offering of online and onsite instruction. However, such a proposition presents substantial logistical challenges, necessitating additional resources, labor, and organizational overhead. This research paper presents a case study conducted during an introductory programming course, which serves as a precursor to a comprehensive, practical software engineering course. Upon easing of COVID-19 related restrictions, the instructors offered both online and onsite versions of this course and obtained student feedback through interviews to draw a comparative analysis.The study outcomes provide crucial insights into students’ preferences with respect to learning modalities in higher education, particularly within the software engineering discipline. The results indicate a predominant preference for the onsite version of the introductory course. Reasons attributed to this preference include enhanced social interactions, greater enjoyment, and increased motivation, thus highlighting the irreplaceable value of face-to-face education.

DESENVOLVIMENTO DE MATERIAIS COMPÓSITOS UTILIZANDO POLIÉSTER E BAGAÇO DE MANDIOCA
Authors: Romanzini Daiane , Hepp Guilherme Gustavo
Published: August 2023

A manihot sculenta, conhecida como mandioca, é uma planta cultivada em praticamente toda a américa, sendo a fécula um dos principais substratos obtidos a partir da raiz. A produção da fécula de mandioca gera resíduos como o bagaço da mandioca, que apesar de ser rico em amido residual e fibras, não possui destinação que agregue valor. Deste modo, o objetivo deste estudo é a obtenção e caracterização de compósitos de resina poliéster contendo como carga o bagaço de mandioca. Os resultados foram comparados com compósitos produzidos com carbonato de cálcio, que é uma carga tradicional usada na indústria. O bagaço obtido foi desidratado, moído e caracterizado através da análise termogravimétrica, apresentando resultados semelhantes aos encontrados na literatura. O compósito foi obtido através da técnica de casting, com teores de 9,1% e 16,6% em massa de bagaço de mandioca, e analisado a partir de ensaios mecânicos e físicos. Os resultados mostraram que a incorporação de bagaço de mandioca aumenta a viscosidade, a densidade e a absorção de água do compósito. Já o tempo de gel apresentou valores próximos àqueles reportados pela resina poliéster, e superior ao do poliéster contendo carbonato de cálcio. A resistência à flexão e o módulo de elasticidade apresentaram resultados semelhantes aos da resina pura. Desta forma, o bagaço de mandioca, um resíduo da produção de fécula de mandioca, se apresenta como potencial carga para ser usada em compósitos com matriz poliéster.

O preço e a disponibilidade de energia desempenham um papel significativo no planejamento econômico de um processo de produção, pois evitar perdas de produtos durante a secagem e armazenamento é essencial para os processos agrícolas. Este trabalho apresenta uma análise da área de cultivo necessária e da viabilidade econômica do reflorestamento de eucalipto e uso de restos culturais para prover a autossuficiência energética na secagem de produtos agrícolas. Nos casos analisados na presente pesquisa, essa prática foi economicamente viável em até 14 das 15 situações. A área mínima necessária para reflorestamento variou de 0,61% a 3,15% da área cultivada para os produtos considerados nesta pesquisa. O cenário de preços instáveis no Brasil após a pandemia de Covid 19 e a guerra Rússia-Ucrânia impactam drasticamente nos resultados.
الإعجازالبیانی فی القرآن الكریم
Authors: شمخی الأستاذ المساعد الدكتور  مینا
Published: August 2023

القرآن الكريم، هذه المعجزة الإلهية تمتلك سمات تعبيرية مهمة. وهذه الصفات تلعب دورا هاما في أن يكون القرآن معجزة. ومن هذه المعجزات معجزة التعبير. عبر التاريخ وحتى الآن، أعرب معظم الأدباء والكتاب والشعراء عن عدم قدرتهم على كتابة شيء مثل القرآن، وهذا الاتجاه يتعزز سنة بعد سنة. يعتقد العلماء أن هناك جوانب لإعجاز التعبير في القرآن تشمل: البلاغة (حلاوة الكلمات وطلاقتها وعدم الاستغناء عنها وعدم التكافؤ في الألفاظ وما إلى ذلك)، والبلاغة (الحرف الأدبية مثل التشبيه والاستعارة وما إلى ذلك)، وسلامة التعبير، عافية التشبيه وموسيقى القرآن الجميلة. يحاول هذا البحث دراسة أنواع مختلفة من إعجاز التعبير في القرآن الكريم تتعلق بالبلاغة والبلاغة باستخدام المنهج الوصفي التحليلي.

لقد كتب الكثير من المؤرخين والمؤلفين عرباً وأجانب مسلمين وغير المسلمين على شخصية الصديقة الطاهرة فاطمة الزهراء™ ، وإن هذا بحثي الموسوم (فاطمة الزهراء™ في رؤى الامام علي(a) قد تحدد في موضوع جانب من حياة الزهراء™ مع الامام عليa والتضحية التي قدمتها هذه المرأة العالمية الفاضلة سواء في ميدان الحياة الزوجية أو في الميادين الاخرى التي سجل لها التاريخ الاسلامي سجلاً حافلاً ومثالاً للزوجة المخلصة ، واتضح في البحث الجانب العقائدي والروحي التي تحملها سيدة نساء العالمين والوقوف جنباً بارزاً في دعم الامام عليa ومسيرته الجهادية في ميادين القتال كما أشار اليها مؤرخو التاريخ الاسلامي وممن كتبوا بالحديث الشريف.

وكشف البحث بساطة الزهراء™ في الحياة العائلية وادارتها للشؤون المنزلية ، وبعض أقوال الامام عليa بحق فاطمة™ والعلاقات الحميمة التي لم يسجل بعدها التاريخ مثل ما سجل لهذه الشخصية ، والتي اتصفت بصفات كثيرة : (فاطمة ، والصديقة ، والبتول ، والمباركة ، والطاهرة ، والزكية ، والرضية ، والمحدثة ، والزهراء ، وبضعة الرسولص ، والحوراء ، والمعصومة ، والرضية) والكثير من الالقاب المباركة ، ونختم بحثنا في نزول الآية المباركة على بيت النبوة بقوله تعالى ﭽ ﮆ ﮇ ﮈ ﮉ ﮊ ﮋ ﮌ ﮍ ﮎ ﮏ ﮐ ﭼ ( ).
التشكيل الصوتي لبعض أبنية جموع التَّكسير

هدفت هذه الدراسة إلى التعرف على تراكيب الجمع غير المنتظم التي تتأثر بتغير حروف العلة باستخدام الدراسة الصوتية، في محاولة لتوضيح أسباب التغيرات التي تطرأ على هذه التراكيب في حالة جمع بعض الكلمات المفردة. وقد استعرض الباحث آراء بعض العلماء قديما وحديثا في علم الأصوات الحديث، تناول فيها تفسير تغيرات تراكيب الجمع الشاذ، ثم حاول تفسير ذلك صوتيا بما يراعي الواقع اللغوي فضلا عن الواقع اللغوي. الاتجاه إلى تحقيق الانسجام في بنية الكلمة العربية، التي تقوم على النظم المقطعية للكلمة العربية، بالإضافة إلى توضيح حالات القبول والرفض للإدغام داخل المقطع الواحد. وخلصت الدراسة إلى أن التناقض بين عنصري الإدغام حيث يكون المثالان متتاليين، وما ينتج عن هذا التناقض في الخلط بين النظام المقطعي وكذلك التناغم الموسيقي يعتبر سببا رئيسيا في العديد من التغيرات في تراكيب الموسيقى. جمع غير منتظم
مشاهير قبيلة الخصام في صدر الإسلام
Authors: عبدالهی الباحثه  حوریه , مفتخری الأستاذ الدکتور حسين
Published: August 2023

ملخص عاش رجال قبيلة الخصم في أنحاء مختلفة من الجزيرة العربية وكانوا في كثير من الأحيان مشركين قبل الإسلام. ومع ظهور الإسلام أسلموا تدريجياً وأخيراً في السنة التاسعة للهجرة، فآمنوا بالنبي وشاركوا مع النبي في الغزوات وحج الوداع، وبعد وفاة النبي شاركوا في معارك وفتوحات مختلفة، وكان لكل منها دور كبير في أحداث التاريخ. إحدى طرق التعرف على المشاهير هي تقديمهم على شكل نص لأن كل قبيلة تُعرف باسم مشاهيرها في التاريخ. المشاهير دائمًا يحتفظون بأسمائهم في التاريخ وتساعد سيرهم الذاتية على تعزيز ثقافتهم الأصلية والقبلية. تعزز مراجعة سيرتهم الذاتية الثقافة الأصلية والقبلية. وتوضيح دورهم في الماضي يساعدنا على تقسيم المشاهير إلى ثلاث فئات: مشاهير سياسيون، مشاهير ثقافيون ودينيون، مشاهير سياسيون عسكريون كانوا في الغالب قادة حروب وأيضا كان لديهم القدرة والموهبة الحربية. وكان مشاهير الثقافة من الشعراء والكتبة. والثالث هم مشاهير الدين والمحدثون في ذلك الوقت. جميع الفئات الثلاث من هؤلاء المشاهير تشاهد بين رجال قبيلة الخصام الذين اختلف أداءهم حسب اختلاف الرؤية والعائلة ومكان الإقامة واهتماماتهم الاجتماعية

شعرية وليم وردزورث وناظر قباني: دراسة مقارنة
Authors: المختار علي خالد
Published: August 2023

يرسم هذا البحث خطوط مقارنة بين الشاعر الإنجليزي "ويليام وردزورث" والشاعر العربي "ناظر قباني". ويحاول عرض أوجه التشابه الرئيسية بين هذين الشاعرين من حيث أسلوبهما وطبيعة الشعر ومصادره. يحاول البحث تسليط الضوء على حقيقة تبدو غير مثبتة بالنسبة للقارئ العادي، وهي أنه على الرغم من انتماء قباني إلى خلفيات وعصور ثقافية مختلفة، إلا أنه تفاعل مع شعرية وردزورث عن علم أو بغير علم بما يجعلها تتناسب مع الشعر العربي الحديث. وجوانبها الثقافية. وتفترض الدراسة الحالية أنهم متفقون تماما في "نظريتهم" الشعرية. ومع ذلك، لا ينبغي تجاهل أن كلاهما يكتبان ضمن الحركة الرومانسية، بعد أن استوعبا مصادرها بالكامل. يقع هذا البحث في ثلاثة مباحث وخاتمة تلخص أهم النتائج التي توصل إليها البحث. يخصص القسم الأول لشعرية وردزورث ومساهماته الشعرية الرئيسية. أما القسم الثاني فيسلط الضوء على شعرية قباني وإسهاماته. الفصل الثالث مقارنة بين الشاعرين

تشخيص أضرار التفسير العلمي من وجهة نظر العلّامة الطباطبائي في تفسير المیزان
Authors: خاكبور الدكتور حسین
Published: August 2023

والتفسير العلمي للقرآن الكريم يعني الاستفادة من النتائج القطعية للعلوم التجريبية في تفسير القرآن. وهذا ما تؤكده بعض الأسباب والأدلة التي تشير إلى أن النتائج القطعية يمكن أن تكون واعدة في بعض الأحيان لفهم القرآن؛ ومع ذلك، فإنه يحتوي أيضًا على مشاكل. ومن الجدير بالذكر أن التفسير العلمي للقرآن يمكن تقسيمه إلى ثلاثة أقسام: الاعتدال والمقارنة. ويحاول البحث الحالي تصوير أضرار هذا النوع من التأويل في تفسير الميزان للعلامة الطباطبائي، وذلك من خلال المنهج الوصفي التحليلي، ذو المنهج النصي والقرآني. ويرى العلامة الطباطبائي أن استخدام هذا النوع من التفسير يمثل مشكلة خطيرة، ويرى أن الإفراط في استخدام هذا التفسير ينطوي على تحديات خطيرة، ويرى أنه سيسبب ضررا كبيرا في مجال التفسير، والتفسير العلمي يتجاهل البعد التوجيهي للقرآن الكريم. وهو نوع من الضرر الأساسي كما أن له ضررًا كبيرًا من حيث المنهجية والغرض.

التعلم بالتعلم هو أمر يدوم طويلاً. يمكن الوصول إلى Malgré tout من خلال نقرتين على الإنترنت، حيث يمكنك تقديم المتدرب القادر على التعلم بنفسي. إن التنسيق التلقائي هو عبارة عن تعريف معرفي. في الوقت الحاضر، يكون المستشعر أقل من مجرد جهاز إرسال للخبرات. إنه أكثر من مجرد مُيسر ومنظم لأعمال التدريب. إنها وظيفة جيدة. هذا الدور الجديد يعني إعادة النظر في الدور التقليدي. ولكن من الصعب جدًا أن تكون السابقة هي الرغبة في تجنب تقنيات المعرفة الصلبة، وتخصيص الكثير من الوقت للتحضير، والتركيز على الأنشطة المحفزة، وتقديم تلميحات دون فشل وتقييم مستمر. إن هذا التغيير هو نتيجة للتقدم العلمي الذي شمل تلك السنوات الأخيرة. إن تركيز المشروع التعليمي على المتدرب وليس على المحتوى أو الطريقة سيكون بمثابة موضوع الدراسة الحالية.
