Quantifying seeds egested by field-collected earthworms: a dynamic and overlooked pool in forest soil seed banks
Authors: McTavish Michael , Rossi Alexandra , Bourchier Robert , Smith Sandy
Published: February 2023

Although awareness of the influence of earthworms on soil seed banks in Canadian forests is growing, there have been few direct field measurements. We used a novel pairing of field-collected earthworms from a central Great Lakes forest in Ontario with a laboratory seed egestion assay to obtain a snapshot of the number of seeds passing through earthworms compared with seeds found in the surrounding soil. We identified a pool of seeds egested by earthworms that accounted for 2.4% of all seeds found in the earthworms and the top 0–10 cm of soil. Individual earthworms contained 0–5 seeds. The large-bodied adult anecic non-native Dew Worm or Common Nightcrawler (Lumbricus terrestris) egested a disproportionate number of seeds for its abundance (50% of egested seeds from 17% of earthworms), but smaller earthworms were also an important source of egested seeds (the other 50%). This small-scale proof-of-concept study demonstrates a method of directly measuring earthworm–seed interactions in the field. It can also detect seeds egested by earthworms below ground that would otherwise be missed by other seed accounting methods and it highlights the importance of granivory by non-surface casting earthworms.
Range expansion of Fisher (Pekania pennanti) in Nova Scotia
Authors: Milton Randy , Doucette Lisa , Williams George , Forbes Graham
Published: February 2023

Fisher (Pekania pennanti) is a medium-sized mesocarnivore that typically occupies mature hardwood and softwood forest where its preferred prey is abundant. In Nova Scotia, Fisher populations are reported as restricted to the mainland; they have been absent from Cape Breton Island for the past 50–80 years. A record of a Fisher on Cape Breton Island in February 2002 prompted us to collate and analyze other records of Cape Breton Island sightings of the species from that date to May 2021. Based on reported sightings, we conclude that Fisher has extended its range from mainland Nova Scotia, apparently crossing the Strait of Canso, and that a breeding population now exists on Cape Breton Island and is expanding. We also comment on possible negative interactions between this expanding Fisher population and the provincially Endangered American Marten (Martes americana) population on the island.
Investigation of the thin layer drying of micropropagated Ocimum basilicum L: Modeling by derived equations, quality characteristics, and energy efficiency
Authors: Kalender Mehmet , Topdemir Aykut
Published: February 2023

This study presents the modeling of thin layer drying of micropropagated Ocimum basilicum L., some quality characteristics of the dried product, and energy consumption analysis for the dryer used. The experimental drying data obtained from a previous article were used in the statistical analyses. Modeling studies were statistically carried out using the experimental data at a 1 m/s airflow rate and a temperature of 30 ?C?50 ?C. The statistical analysis showed that the Verma equation was the best-fit model with the lowest chi-square (?2) and AIC values at all temperatures studied. From statistical analyses using derived drying models, it was found that the D9 equation having a ?2 value of 0.0146 and an AIC value of -528.0, was the best model fitting to experimental data. The total phenolic content, flavonoid, and antioxidant capacity of dried basil samples were measured as (2.538 ? 0.029) mg GAE/g, (2.017 ? 0.088) mg quercetin/g, and (2.263 ? 0.001) mmol TEAC/100 g d.w., respectively. From FTIR spectra, dried basil samples had typical functional groups. SEM images showed that a collapse in the surface of the leaves occurred. But, this collapse is not affecting the functional groups on the surface of the leaves. From energy consumption analyses, the optimum drying temperature was found to be 40?C. The SMER, MER, and SEC values calculated from energy consumption analysis at 40?C were 0.0043 kg/kWh, 0.0007 kg/h, and 234.81 kWh/kg, respectively.
Class probability distribution based maximum entropy model for classification of datasets with sparse instances
Authors: Saravanan Arumugam , Anandhi Damotharan , Srividya Marudhachalam
Published: February 2023

Due to the digital revolution, the amount of data to be processed is growing every day. One of the more common functions used to process these data is classification. However, the results obtained by most existing classifiers are not satisfactory, as they often depend on the number and type of attributes within the datasets. In this paper, a maximum entropy model based on class probability distribution is proposed for classifying data in sparse datasets with fewer attributes and instances. Moreover, a new idea of using Lagrange multipliers is suggested for estimating class probabilities in the process of class label prediction. Experimental analysis indicates that the proposed model has an average accuracy of 89.9% and 86.93% with 17 and 36 datasets. Besides, statistical analysis of the results indicates that the proposed model offers greater classification accuracy for over 50% of datasets with fewer attributes and instances than other competitors.

Published: February 2023

Background and purpose: Robotic-assisted total knee arthroplasty (RATKA) is an alternative surgical treatment method to conventional total knee arthroplasty (COTKA) that may deliver better surgical accuracy. However, its impact on patient outcomes is uncertain. The aim of this systematic review of randomized controlled trials (RCTs) is to evaluate whether RATKA could improve functional and radiological outcomes compared with COTKA in adult patients with primary osteoarthritis of the knee.Methods: We searched Ovid MEDLINE, EMBASE, Scopus, and the Cochrane Library to identify published RCTs comparing RATKA with COTKA. 2 reviewers independently screened eligible studies, reviewed the full texts, assessed risk of bias using the Risk of Bias 2.0 tool, and extracted data. Outcomes were patient-reported outcomes, range of motion, and mechanical alignment (MA) deviation and outliers, and complications.Results: We included 12 RCTs involving 2,200 patients. RATKA probably results in little to no effect on patient-reported outcomes (mean difference (MD) in the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score of –0.35 (95% confidence interval [CI] –0.78 to 0.07) and range of motion (MD –0.73°; CI –7.5° to 6.0°) compared with COTKA. However, RATKA likely results in a lower degree of MA outliers (risk ratio 0.43; CI 0.27 to 0.67) and less deviation from neutral MA (MD –0.94°; CI –1.1° to –0.73°). There were no differences in revision rate or major adverse effects associated with RATKA.Conclusion: Although RATKA likely results in higher radiologic accuracy than COTKA, this may not be clinically meaningful. Also, there is probably no clinically important difference in clinical outcomes between RATKA and COTKA, while it is as yet inconclusive regarding the revision and complication rates due to insufficient evidence.

The use of modern antibacterial agents and antiseptics in modern orthopedics does not always prevent infectious complications. Currently, two-stage surgical treatment with the implantation of an antimicrobial spacer is common. This method increases the duration of treatment, causing additional surgical trauma. The use of bioresorbable material with additional antibiotic impregnation simultaneously with the rehabilitation of the infectious focus can be considered a promising direction for improving the effectiveness of treatment of chronic osteomyelitis and reducing the treatment time of this group of patients. The main group consisted of rabbits with an experimental model of osteomyelitis followed by rehabilitation and one-stage replacement of the bone defect with bioresorbable material impregnated with vancomycin (n=12), and in animals of the comparison group (n=12) - two-stage surgical intervention with a similar material. Morphological studies were performed on animals of both groups on the 45th and 90th days after operations with replacement of a bone defect with a bioresorbable material with vancomycin. On the 45th day after the operation, the intensity of the processes of formation of newly formed bone tissue and restructuring of the osteoarthritis replacement material was more pronounced in the main group (28,2 vs 23,5%). Two-stage treatment is characterized by a more pronounced formation of fibrous tissue, the area of which in dynamics increased by 1,4 times (from 27,6 to 39,3%), with a single-stage method of treatment, this indicator increased only by 2% (from 22,9 to 24,9%). The infectious process was stopped in all experimental animals. The effectiveness of one-stage surgical treatment seems to be determined by a faster onset of osteohistogenesis in the area of a local osteomyelic defect when biocomposite is administered immediately after the purulent focus is sanitized. In addition, the absence of repeated surgical trauma with the loss of additional bone volume when removing the cement spacer during two-stage treatment is likely to play a significant role.

The issues of skin regeneration during thermal injury are an urgent problem of modern biomedicine. The quality and speed of restoration of the damaged epidermis largely ensures the quality of life of patients. The optimal method of wound treatment depends, inter alia, on knowledge of the structural and functional features of the extracellular matrix of the connective tissue of the dermis, including the amphora and fibrous components. Material and methods. In a study on adult Wistar rats, we modeled second degree burns of the posterior surface of the torso with an area of 1 0% of the body surface for the purpose of histological and immunohistochemical assessment of the involvement of mast cells in the wound process and their importance in the implementation of collagen fibrillogenesis in various protocols for the treatment of burn wounds. A planimetric analysis was carried out to obtain quantitative data on the content of mast cells per mm2 of the skin, their histotopography and morphofunctional typing were determined to assess the secretory activity. Results. The study revealed that the burn wound caused an increase in the population of skin mast cells with certain histotopo-graphic patterns, in particular, predominant accumulation in the peripheral region of the alteration zone. An increase in the secretory activity of mast cells led to a systemic reconstruction of the extracellular matrix, stimulating the healing processes by activating the formation of the fibrous component of the connective tissue. After thermal exposure, a significant increase in tryptase expression in the mast cell population was revealed when using water with an increased content of molecular hydrogen. Conclusion. The revealed features of various protocols of wound management in the efficiency of regenerative processes are due to the degree of involvement of mast cells in fibrillogenesis using direct and indirect pathways. Thus, the molecular mechanisms of extracellular matrix remodeling, induced by the secretory activity of mast cells, are promising targets for intensifying the regenerative effects of pharmacological agents.

Earlier, in mice after a 30-day space flight on the Bion-M1 biosatellite, we found signs of a negative effect of weightlessness on the structure of myelinated fibers of the spinal cord tracts; these findings indicate their involvement in the pathogenesis of hypogravitational motor syndrome (HMS). In the present study, under conditions of hypogravity modeling by the hindlimb unloading, we obtained data on destructive changes in the myelinated fibers of the motor posterior corticospinal tract (tractus corticospinalis posterior), sensitive anterior spinocerebellar tract (tractus spino-cerebellaris anterior), and the gracile fascicle (fasciculus gracilis), as well as in the tibial fascicle (fasciculus tibialis) of the sciatic nerve of mice 30 days after unloading. The obtained data confirm our hypothesis on the role of disturbance in the processes of myelination of nerve fibers during the development of HMS, both during space flight and under conditions of simulating hypogravity on Earth. Morphometric analysis after a 7-day period of readaptation did not reveal signs of restoration of pathological changes in myelinated fibers that arose after 30 days of hanging. However, preventive gene therapy (administration of a gene construct providing the synthesis of recombinant vascular endothelial growth factor, glial cell line-derived neurotrophic factor, and neural cell adhesion molecule, prior to hindlimb unloading) has been shown to be effective in the preservation of myelinated fibers in projection anterior spininocerebellar tract, compared with control animals that did not receive gene therapy. The research carried out at this stage gives ground to make a preliminary conclusion about the advisability of developing methods of preventive gene therapy to prevent the development of GDS during long-term space flights.

In the past few decades, there has been a decline in male fertility worldwide. The article is devoted to the study of the reproductive health of subfertile men. Purpose of the work: analysis of the biochemical composition of sperm plasma, spermogram and sperm morphology in subfertile men of reproductive age. The study included 85 patients aged 25 to 45 years, who were under observation in the clinic of Professor M.A. Florova (Samara): 60 patients seeking help to optimize reproductive health and procreation planning (a group of subfertile men, spermogram indices have deviations) and 25 clinically healthy men - a comparison group (control, spermogram indices are within the WHO norm). In subfertile men, morphological abnormalities of spermatozoa and changes in the biochemical composition of sperm plasma (increased concentration of transamination enzymes) were established. Spermatozoa with immature chromatin were identified. Electron microscopic analysis revealed fragmentation of sperm DNA: the highest percentage of spermatozoa with fragmented DNA was found in subfertile men (more than 22%).

Due to its extraembryonic origin, the umbilical cord retains regenerative molecules of the fetal phenotype The cell-free matrix of the human umbilical cord as the basis of various tissue-engineering structures (TES) for regenerative medicine can contribute to the repopulation of transplanted matrices by patient-specific cells. The aim of the work was to study in vitro the cytotoxic properties of a tissue-engineered lyophilized cell-free matrix made by the detergent method from the human umbilical cord Warton jelly with respect to human skin fibroblasts, as well as the effect of this matrix on the viability and growth of cells of the cerebral cortex, liver, spleen, articular cartilage, heart and skin of various laboratory animals during organotypic cultivation. Using the MTT test, it was revealed that the tissue-engineered acellular lyophilized matrix of the human umbilical cord does not show a toxic effect on human dermal fibroblast. When using the method of organ cultures, differences were revealed in the influence of the tissue-engineered matrix on the migration of cells from explants of tissues of different organs of various laboratory animals, their growth dynamics and viability, which may be due to species specificity, which must be taken into account when choosing test systems. The most noticeable positive effect of the matrix on the growth dynamics and viability of articular cartilage explant cells was found. Adhesion to the matrix of cells of the cerebral cortex of the Vietnamese lop-bellied pig as well as cells of the spleen of a guinea pig was revealed. The cell-free human umbilical cord matrix can be used in the creation of acellular matrices for the treatment of deep dermal and articular cartilage damages.
Effectiveness of cell and gene therapy in treatment of obliterating diseases of the arteries in the lower extremities: a review

Published: February 2023

The lack of significant progress in improving the results of treatment for patients with chronic lower limb ischemia (CLLI) determines a necessity to search new approaches to solve this problem. One of the promising methods for treatment of patients with CLLI is therapeutic angiogenesis. Gene and cell therapy clinical trials for this pathology have been carried out in the world for more than 20 years and showed conflicting results. It is extremely difficult to produce a drug based on cellular material, therefore the development of gene-based therapies is more promising. In most of the analyzed studies, patients with critical limb ischemia, i.e with initially with a high risk for major amputation, were included. Since the process of neoangiogenesis takes several months, it seems more logical to use that option for treatment in the earlier stages of the disease.

VEGF-165 is the most studied angiogenic agent. Only VEGF-165 is registered as a drug for treatment of patients with CLLI. There are publications on the effectiveness of treatment with a plasmid VEGF-165-gene therapy in patients with stages II and III of CLLI according to the FontaineA.V. Pokrovsky classification in a five-year follow-up study.

This discussion article presents the theoretical background and results of our own histological study of the ampulla of the papilla of Vater in various animals to explain the absence of the gallbladder in some animals. In particular, the authors studied the structure of the duodenal mucosa in rats and rabbits. They suggest that the evolutionary loss of the gallbladder in some animals is associated with the need for rapid movement in space and high maneuverability. The realization of these properties may be hindered by a fluid-filled organ.

Published: February 2023

A pellet dryer machine is a tool that makes it easy to dry pellets so it doesn't have to require sunlight to dry the pellets. Various methods have also been widely used to control the temperature on the machine. One of the obstacles experienced is controlling the temperature so that it remains stable and has a good response time. In this journal, a pellet drying machine with PID (proportional integral derivative) method will be designed to keep the temperature stable. The temperature that makes the setpoint is 100 degree C. In the design carried out, it is by comparing sistems that are given Proportional control, Proportional and Integral (PI) control and Proportional Derivative (PD) control. For the controller used, it is an Autonics TK4S type controller. In the control, PID tuning will be carried out which will later be carried out variations of each Kp, Ki, and Kd values.

Published: February 2023

The water turbine must be specially designed according to the calculation of its energy potential, proportional to the height of the falling water and the discharge. This research is conducted to study the solution fluid engine that functions as a pico hydro water turbine, namely a centrifugal blower with a simple construction, operating at low head, small discharge, easy installation and operation and low price. The blower used in this test is a blower that is already on the market with an impeller diameter of 15 cm, inlet size of 2 inches. The test was carried out at a constant head (falling water height) of 5 m. The working principle of the blower is reversed, that is, water from a certain height flows through the rapid pipe and enters the exhaust side of the blower until the water moves the blower and exits through the blower inlet to the draftube. The purpose of this study was to determine the effect of modification of the blades on the increase in efficiency of the picohydro turbine. This study uses an analytical method with testing parameters based on calculating the value of water discharge, water power, torque, turbine mechanical power and turbine efficiency. To increase the power and efficiency of the blower as a turbine, modifications are made to the blower blades. With the modification of the blower blades, the turbine efficiency increases by 10 percents from before the modification.

ATS (Automatic Transfer Switch) merupakan sistem untuk menghubungkan beban dengan dua sumber tenaga listrik (sumber utama dan cadangan) yang terpisah untuk menjaga ketersediaan aliran daya listrik menuju beban. Pembangkit Listrik Tenaga Surya (PLTS) saat ini sudah sangat sering digunakan di masyarakat. Dalam hal memprioritaskan sumber energi listrik dari PLTS dijadikan sumber listrik yang utama sangatlah baik, akan tetapi untuk menghasilkan energi listrik PLTS sangat bergantung kepada intensitas penyinaran matahari, oleh karenanya kita masih masih memerlukan suplai cadangan yakni dari PLN (Perusahaan Listrik Negara). Tujuan dari penelitian ini membangun sebuah sistem ATS untuk memaksimalkan sumber energi listrik yang bersumber dari PLTS dengan di-backup oleh PLN, alat ini berbasis sensor tegangan baterai untuk menentukan kapan saat beban dialihkan ke sumber dari PLTS atau PLN. Hasil percobaan didapatkan hasil data suplai listrik akan berpindah ke PLN saat tegangan baterai pada PLTS terdeteksi dibawah 11,1 VDC (baterai habis) dan akan kembali lagi suplai listrik dilayani oleh Inverter apabila tegangan baterai tertingginya tercapai (baterai penuh) mencapai 13 VDC. ATS ini juga bisa menjadi UPS (Uninterruptible Power Supply) yakni untuk memprioritaskan sumber dari listrik PLN dan di-backup oleh PLTS dengan memindahkan selector switchnya ke arah lampu indikator PLN.

The purpose of this study was to help determine the effectiveness of inquiry-based learning (IBL) over the traditional method. It was also to identify difficulties associated with the use of the inquiry-based learning method This was investigated using the two methods of teaching to teach the concept of measurement of temperature to Basic 8 students of K.O Methodist Junior High School ‘B’ in Kumasi, Ghana. The research design was quasi-experimental. Tests on the concept of heat and temperature (TCHT) were used to obtain responses from Sixty students who were sampled purposively from all students in Basic 8 and were divided into control and experimental groups. Five teachers were interviewed on the challenges of teaching science through the IBL approach. Data was collected under two stages: the pre-experimental, experimental, and post-experimental stages. It was recorded from the independent sample T test that, there was significant difference between the use of the inquiry-based method of teaching and learning and the traditional method of teaching in favour of the inquiry-based method at a confidence interval of 95%. Students who were taught using the inquiry-based method of teaching and learning performed better than those who were taught with the traditional approach. The research, however, concluded that due to factors such as lack of technical know-how, space on timetable etc. among others, teachers are unwilling to use the inquiry method. The study recommended among other things that teachers should adopt the improvisation technique if they want to use the IBL.

Field research was conducted in the central research farm of Sher-e-Bangla Agricultural University (SAU), during the period from October 2020 to March 2021. The experiment was a layout with RCBD design to evaluate the effect of selected fungicides (Indofil, Mancer, and Ridomil Gold), micronutrients (Zinc, Boron, and Magnesium), and botanicals (neem and eucalyptus leave extract) on purple blotch complex of onion. Data were collected on percent disease incidence and percent disease index, the number of leaves per plant, leaf length, bulb diameter, bulb weight (fresh and dry), and yield. The local cultivar Faridpuri was used as a tested variety. Among the selected fungicides, Ridomil Gold gave a better result than other fungicides in controlling the percent disease incidence (52.67%) and percent disease index (49.00%) with the highest number of yield qualities per plant. In addition to this, the highest bulb diameter (18.23 cm), single bulb weight (47.98 g), fresh weight (3.16 Kg/plot), and dry weight (2.88Kg/plot) were also obtained in Ridomil Gold treated plots. This treatment also gave better yield performance (9.60 t ha-1) followed by Indofil (8.20 t ha-1) and Mancer (7.90 t ha-1), and increased yield by 54.34% over the control treatment. From the study, it was also found that among the micronutrients, boron gave more satisfactory results than botanicals.

Authors: Tülek Remziye
Published: February 2023

The structural and optical properties of InxGa1-xN/InyGa1-yN multi quantum well (MQW) light emitting devices with/without electron injection layers were studied. The samples with electron injection layer consist of step-graded (GIE) and two step staircase (SEI) electron injection layer between n-type GaN and MQWs active region. Edge and screw type of dislocation densities were deduced from High Resolution X-Ray Diffraction (HR-XRD) curves and no significant difference were realized. The zeroth and higher order satellite peaks were more clearly observed in the sample without electron injection layer. Optical characterization was carried out by temperature dependent photoluminescence (PL) technique. It was found that the PL densities of samples with step-graded and two step-staircase electron injection layers had almost two times lower temperature dependence compared to the reference sample without electron injection layer. On the other hand, the line width of the photoluminescence peak associated with MQWs is much narrower at low temperature for sample without electron injection layer than the other two samples.

Inequality in economic development is an economic problem that is often felt by developing countries. In Indonesia, one of the regional areas that has not yet experienced equal distribution of economic development is the regencies/cities of the Sumatera Region. This study aims to determine regional groups and compare the results of grouping with the K-Medoids and CLARA methods. The K-Medoids and CLARA methods are non-hierarchical methods that are strong against outliers. While the best selection method is done by comparing the silhouette coefficient. The results obtained in this study using the K-Medoids and CLARA methods with 2 groups being better than forming 3 groups. The K-Medoids method resulted in cluster 1 as many as 59 districts/cities and cluster 2 as many as 95 districts/cities. Meanwhile, the grouping of districts/cities using the CLARA method with 2 groups resulted in cluster 1 as many as 74 districts/cities and cluster 2 as many as 80 districts/cities. From the comparison of the two methods, the silhouette coefficient values using the K-Medoids and CLARA methods are 0.13 and 0.15 respectively. Therefore, the CLARA method with 2 groups gave better cluster results

Shallots are one of the leading spices that are widely used by humans as food seasoning and traditional medicine. The price of shallots always fluctuates which can affect the buying and selling of consumers and producers. Therefore, forecasting is used as a reference to be able to predict the price of shallots in the future and can provide convenience to the public for the condition of shallot prices in the next period. The forecasting method used is the fuzzy time series (FTS) method. FTS is a method whose forecasting uses data in the form of fuzzy sets sourced from real numbers to the universe set on actual data. Forecasting models used in this study are Singh's FTS model and Cheng's model. The data used is monthly data on shallot prices in West Sumatra Province for the period January 2018 to March 2022. The results obtained in this forecast are the Singh model FTS has a smaller MAPE value of 4.41% with a forecasting accuracy value of 95.59 %. This means that Singh's FTS model is better at predicting the price of shallots in West Sumatra Province.

One of the time series data modeling is the ARMA model which assumes constant volatility. However, in economic and financial data, there are many cases where volatility is not constant. This results in the occurrence of heteroscedasticity problems in the residuals, so a GARCH model is needed. In addition to heteroscedasticity, another problem with residuals is the asymmetric effect or leverage effect. For that we need asymmetric GARCH modeling. This study aims to compare the accuracy of the ARMA, GARCH, and asymmetric GARCH models. This research is an applied research. The data used is daily stock return data from February 2020 to February 2022 as many as 488 data. The results showed that the best model in modeling stock return volatility is ARMA(0,1). The accuracy of this model is very good with MAD value of 0,0018644 and RMSE value of 0,0025352.

Numerous pathogenic microorganisms use the enzymes trehalose-6-phosphate phosphatase (TPP) to biosynthesize the sugar trehalose from trehalose-6-phosphate (T6P) as part of their infection and proliferation processes. In order to build new generation candidate medications to inhibit TPP using in silico approaches, the current work is being done. The majority of the 10 phytochemicals from Moringa oleifera that were used in docking studies with the 3D model of TPP had good binding affinities to the enzyme, with campesterol and stigmat-4-en-3-one showing the highest affinities (Binding energies of - 7.8 kcal/mole and -8.0 kcal/mole, respectively), when compared to the commonly used commercial drug isoniazid (Binding energy of –6.0 kcal/mole).The active site of TPP sequences, which coordinates Mg2+ and is necessary for catalysis, has been discovered to bind to phytochemical leads during docking. Binding poses and distance measurement of TPP-phytochemical complexes of 5-Hydroxymethylfurfural, Citronellol, Xylitol, 2,4-Di-tert-butylphenol, Palmitoleic acid, cis-Vaccenic acid, Phytol, Cyclopentane, 1,1-[3-(2-cyclopentylethyl)-1,5-pentanediyl]bis-, Campesterol and Stigmat-4-en-3-one reveals that the lead phytochemicals were in close proximity with most of the active site amino acids (distance range from 1.88 to 3.77 Aº). This demonstrates the close affinity between the enzyme and the leads, which may open the door to the development of new generation medications to treat diseases caused by pathogenic microorganisms that produce TPP.

The Cognitive Mechanisms Underlying the Concept of سرعة (Speed) in Arabic
Authors: Lahlou Hicham
Published: February 2023

Despite the wide range of studies on how students’ past knowledge influences their understanding of scientific terminology, few studies were conducted to compare non-scientific language with scientific language, or rather everyday language with scientific language, from a cognitive linguistic perspective. The present paper aims to determine the cognitive mechanisms, i.e., image schemas, conceptual metaphor, and conceptual metonymy, which underpin the conceptualisation of the Arabic term سرعة (speed), using a conceptual metaphor theory framework. Thus, the research question guiding this study is: What cognitive mechanisms underlie the concept of سرعة (speed) in Arabic? The findings of this study will shed light on how Arab speakers conceptualise this term, demonstrating their background knowledge of the term compared to its scientific meaning. The article adds to the growing body of cognitive linguistics research on the conceptual processes behind physics terms. The data was collected from the Arabic Web Corpus (arTenTen) using the Sketch Engine. The findings demonstrated that VERTICATLITY and SCALE schemas are the most dominant image schemas that anchor the conceptual meaning in Arab speakers’ perceptions of the term under investigation and the discourse in which it is employed, as well as offer the concrete basis for conceptual metaphors. The conceptual metaphor CHANGE IS MOTION (LOCATION) was also shown to be active in motivating the conception of SPEED in Arabic.
