In this study, the fatty acid compounds in the muscle tissues of Mesopotamian catfish (Silurus triostegus, Heckel, 1843) and Shabut (Arabibarbus grypus, Heckel, 1843), which live in Ilısu Dam Lake on the Tigris River and have economic importance. For fatty acid analysis, muscle tissues were taken from the samples obtained from local fishermen, placed in tubes and lipids were obtained by applying chloroform/methanol method. The methylation steps of fatty acids in the samples were performed in accordance with TS EN ISO 12966:2 (TS EN ISO 12966-2., 2017) method. The total fatty acid content of saturated fatty acids (SFA) value was detected as 27,97 ± 0,26 in A.grypus, 32.46 ± 0.37 in S. triostegus, The value of Monounsaturated Fatty Acids (MUFA) varied between 42.63 ± 0.6% in A. grypus and 41.5 ± 0.51% in S. triostegus. Total polyunsaturated polyunsaturated acids (PUFA) ranged between 21.83 ± 1.49 for A. grypus and 25.82 ± 1.94 for S. triostegus. MUFA values in all samples were higher than SFA and PUFA values for both fish species. Docosa Hexaenoic Acid (DHA) and Eicosa Pentaenoic Acid (EPA) are commonly consumed omega-3 types. A. grypus and S. triostegus are within the recommended limits for EPA (C20:5n3) and DHA (C22:6n3). For A. grypus, ω3/ω6 values were (1,06); for S. triostegus ω3/ω6 values were (1,38). When the ω3/ω6 values of both fish species were analysed for human health, it was determined that the ω3/ω6 values of omega fatty acids A. grypus and S. triostegus were above 1. As a result information on the composition of 20 types of fatty acids and ω3/ω6 amounts were obtained in muscle tissue of A. grypus and S. triostegus species living in Ilısu Dam Lake and most preferred by local people. The levels of fat and its components in these species, which may cause different problems when accumulated in the body as a result of changing consumption habits, were indicated in the study.

Geçmişten günümüze çeşitli tıbbi uygulamalarda kullanılmak üzere, vücut içinde etkin ve stabil kontrast ajanlarının geliştirilmesi için kapsamlı araştırmalar yapılmıştır. Özellikle tıbbi ultrason görüntüleme esnasında yüksek kontrast sağlayabilme yetenekleri ile dikkat çeken mikro-kabarcıklar (MBs), gaz çekirdeklerinin sıkıştırılması ve kanın ultrasonla etkileşimi sonucu deforme olarak, MBs’ nin kabuğundaki büzülme-genleşme hareketleri ile yaygın bir kontrast ajanı olarak kullanılmaktadır. MBs’ nin kabarcıkların çekirdek ve kapsül yapısı, kabarcığın stabilitesini ve bununla beraber etkinlik süresine etki etmektedir. Literatürdeki çalışmalar, farklı Q değerlerine sahip gaz çekirdek yapılı MBs’ nin lipit, protein, polimer ve sürfaktan gibi malzemelerle kapsüllendiğini göstermektedir. Bu kapsülasyon malzemeleri ile oluşturulan MBs’ nin ise tıbbi ultrasonik görüntülemede kullanılabilmesi için yeterli yapısal stabiliteye, etkin parçacık boyutuna ve yüksek kontrasta aynı anda sahip olması beklenmektedir. Bu araştırmada ise daha önce literatürde çalışılmamış olan n-pentan (C5) ve perfloropropan (C3H8) gazlarının sol-jel yöntemiyle silika (SiO2) kapsülasyonu yapılarak, 1-5 mikrometre arasında stabil MK elde edilmesi ve kontrast ajanı olarak kullanılması hedeflenmiştir. SiO2-C5 için en uygun sürfaktan miktarının ağırlıkça %10 olduğu belirlenmiş olup, amonyak katalizörünün artırılması ile ortalama hidrodinamik partikül boyutunun ise azaldığı gözlemlenmiştir. İdeal olarak belirlenen SiO2-C5 sistemleri, emülsiyon içinde 7 gün, hava ile etkileşiminde ise 10 dakika boyunca stabilitesini koruduğu görülmüştür. SiO2-C3H8 sistemleri için, çekirdek yapı miktarının arttırılması ile ortalama hidrodinamik parçacık boyutunun azaldığı, 15 güne kadar emülsiyon içinde, 15 dakika hava ile etkileşimi sonrasında stabilitesini koruduğu görülmüştür.

Published: August 2024

Helianthus annus L., known as sunflower, is belong to Asteraceae family. This family is one of the biggest angiosperm plant families in between dicotyledons and cultivated sunflower is an important oil plant all around the world. Chloroplast DNA analysis reveals that the origin of the genus dates back to 4.75 to 22.7 million years ago. Sunflower seeds contain 18% protein, 15% cellulose, 9% water, 14% minerals and carbohydrates. In general, sunflower seeds contain 35% to 50% oil by weight. The oil content of sunflower had been specified from 36.9% to 50.2%. These features have made sunflower an important plant worldwide. In principle, the breeding of sunflowers aims to improve the oil content and to get a plant resistant to disease. All breeding methods both classical and biotechnological methods try to contribute these aims. With the help of technology DNA markers have provided useful information about polymorphism, genetic relatedness, and diversity. Technology advances in breeding, especially the use of molecular markers, offer new strategies to obtain high-yielding and resistant plants through DNA sequences located at a known location on the chromosome. Sunflower has been a model plant in Asteraceae family in molecular marker studies because of its economic importance. Many molecular marker studies have been conducted against biotic and abiotic stress conditions, increase oil content and nutritional value, and water consumption etc. Considering its economic value, current studies on the plant will shed light on future studies and improvements can be observed in many yield criteria such as water consumption, harvest efficiency, resistance to pests.

Revisiting the Tertiary-induced Binary Black Hole Mergers: The Role of Superthermal Wide Tertiary Eccentricity Distributions
Authors: Su Yubo , Liu Bin , Xu Siyao
Published: August 2024

Recent studies show that the eccentricity distribution of wide binaries (semimajor axis ≳103 au) observed by Gaia tends to favor large eccentricities more strongly than the canonical thermal distribution (P(e) ∝ e)—such distributions are termed “superthermal.” Motivated by this observation, we revisit the formation channel of black hole (BH) binary mergers in triple stellar systems and study the impact of superthermal eccentricity distributions in the outer binaries. We explore the persistence of the highly eccentric outer orbits after each component in a stellar triple has undergone mass loss due to supernova explosions. We find that the outer eccentricity distribution can remain significantly superthermal for modestly hierarchical BH triples satisfying a
in/a
out ≳ 0.005 (where a
in and a
out are the semimajor axes of the inner and outer orbits), and are otherwise shaped by mass-loss induced kicks and dynamical instability. We then study the impact of these different outer eccentricity distributions of the remaining BH triples on mergers via the tertiary-induced channel. Of interest, we find that mergers can sometimes be produced even when the initial stellar orbits are near alignment (not subject to the von-Zeipel–Lidov–Kozai effect; ZLK effect) as long as the system is sufficiently hierarchical. On the other hand, although the impact of the octupole-order ZLK effect is much greater when the outer binary is more eccentric, we find that the merger fraction only changes modestly for extreme outer eccentricity distributions because the largest eccentricities tend to lead to dynamical instability.
Perturbation Spectra of Warm Inflation in f(Q, T) Gravity
Authors: Shiravand Maryam , Farhoudi Mehrdad , Goodarzi Parviz
Published: August 2024

We investigate the warm inflationary scenario within the context of the linear version of f(Q, T) gravity, coupled with both the inflaton scalar field and the radiation field, under the conditions of the strong dissipation regime. First, we calculate the modified Friedmann equations and the modified slow-roll parameters. Subsequently, we apply the slow-roll approximations to derive the scalar power spectrum and the tensor power spectrum. Also, we develop formulations of the scalar and tensor perturbations for the f(Q, T) gravity with the warm inflation scenario. Furthermore, we scrutinize two different forms of the dissipation coefficient, a constant and a function of the inflaton field, to determine the scalar spectral index, the tensor-to-scalar ratio, and the temperature for the power-law potential case. By imposing some constraints on the free parameters of the model, we attain results in good agreement with both the Planck 2018 data and the joint Planck, BK15, and baryon acoustic oscillation data for the tensor-to-scalar ratio, and consistent results aligned with the Planck 2018 data for the scalar spectral index. In addition, the obtained results are within the range of observational data for the amplitude of the scalar power spectrum. Consequently, we are able to revive the power-law potential that was previously ruled out by observational data. Moreover, for both dissipation coefficients, the model leads to a scalar spectral index with the blue and red tilts in agreement with the Wilkinson Microwave Anisotropy Probe 3 yr data.

Rings and gaps are among the most widely observed forms of substructure in protoplanetary disks. A gap–ring pair may be formed when a planet carves a gap in the disk, which produces a local pressure maximum following the gap that traps inwardly drifting dust grains and appears as a bright ring owing to the enhanced dust density. A dust-trapping ring would provide a promising environment for solid growth and possibly planetesimal production via the streaming instability. We present evidence of dust trapping in the bright ring of the planet-hosting disk Elias 2-24, from the analysis of 1.3 and 3 mm Atacama Large Millimeter/submillimeter Array observations at high spatial resolution (0.″029, 4.0 au). We leverage the high spatial resolution to demonstrate that larger grains are more efficiently trapped and place constraints on the local turbulence (8 × 10−4 < α
turb < 0.03) and the gas-to-dust ratio (Σ
g
/Σ
d
< 30) in the ring. Using a scattering-included marginal probability analysis, we measure a total dust disk mass of

Steady states and spatiotemporal dynamics of a diffusive predator-prey system with predator harvesting
Authors: Yu Rongjie , Yu Hengguo , Zhao Min
Published: August 2024

From the perspective of ecological control, harvesting behavior plays a crucial role in the ecosystem natural cycle. This paper proposes a diffusive predator-prey system with predator harvesting to explore the impact of harvesting on predatory ecological relationships. First, the existence and boundedness of system solutions were investigated and the non-existence and existence of non-constant steady states were obtained. Second, the conditions for Turing instability were given to further investigate the Turing patterns. Based on these conditions, the amplitude equations at the threshold of instability were established using weakly nonlinear analysis. Finally, the existence, direction, and stability of Hopf bifurcation were proven. Furthermore, numerical simulations were used to confirm the correctness of the theoretical analysis and show that harvesting has a strong influence on the dynamical behaviors of the predator-prey systems. In summary, the results of this study contribute to promoting the research and development of predatory ecosystems.

Članek analizira mitološke predstave o škratih med Slovenci v Beneški Sloveniji (Nediške in Terske doline) v Italiji v primerjavi s predstavami o teh bajčnih bitjih v Sloveniji in med njihovimi romanskimi sosedi – Italijani in Furlani. Pomembna lokalna značilnost škratov v Beneški Sloveniji je njihov izvor iz duš dojenčkov, ki so umrli pred krstom. Ta značilnost določa tako funkcije kot tudi habitate teh likov, pa tudi zaplete mitoloških zgodb o njih. Povezava škratov z nemirnimi dušami se krepi s prepričanji o njihovi povezavi z vremenskimi pojavi. Na frazeološki ravni (tako v literarnem jeziku kot tudi v narečjih) se škrati povezujejo z neposlušnimi, nagajivimi otroki.
MULTI-OBJECTIVE OPTIMIZATION STUDY OF RESIDENTIAL ENERGY CONSUMPTION BASED ON EDH AND THE STOCHASTIC OPERATION OF AIR CONDITIONING
Authors: Dang Yichen , Yao Jian
Published: August 2024

Current requirements for residential energy-efficient design solutions in China are relatively homogeneous, requiring only improvements in overall building energy performance, often ignoring the energy differences between different residential housing units. This paper proposes a multi-objective research framework based on an occupant behavior model of air conditioning and a Non-dominated Sorting Genetic Algorithm-II (NSGA-II) to study energy-efficient design solutions for residential envelopes. The optimal energy-saving design scheme has a 22.56% and 35.34% reduction in energy consumption difference between residential units and overall building energy consumption, respectively, both of which have been optimized substantially. Moreover, the overall energy performance of the building can be improved when the “energy performance difference between housing units” (EDH) is reduced, which verifies that EDH is an important criterion for improving the energy performance of residential housing units.
QUANTIFICATION OF CARBON POTENTIAL OF CONSTRUCTION WASTE TREATMENT: A CASE STUDY OF GUANGZHOU, CHINA
Authors: Liu Jingkuang , Tan Xiaomin , Zheng Jiaxi , Wang Zhenshuang
Published: August 2024

Emission reduction in the construction sector is essential for China to achieve its carbon peaking and carbon neutrality goals. Construction waste recycling represents an important step in reducing the construction industry’s carbon emissions; however, construction waste recycling potential has received little attention from the industry to date. This paper adopts the Life Cycle Assessment method, constructs a carbon potential quantification formula for different construction waste treatment modes, and evaluates the economic benefit of these methods. The study’s main results are as follows. (1) For each unit (t) of construction waste disposal, the carbon potential of close-range off-site recycling is the lowest, that of public landfill is the highest, and that of recycling is intermediate. (2) The economic benefit evaluation shows that under the same conditions, the lowest total disposal cost for construction waste per unit (t) is via recycling and resourcing, indicating that this approach combines economic benefits, environmental friendliness, and sustainability. (3) Eco-friendly bricks produced by construction waste recycling have reduced carbon potential requirements compared to traditional bricks; thus, the construction waste treatment process plays a successful role in reducing carbon potential. This study’s conclusions enrich and improve the theory of construction waste resource management and can be used as a reference basis for the government to formulate emission reduction strategies for the construction industry and provide guidance for enterprises related to construction waste recycling.
The Costs and Concerns of Energy Transition
Authors: Imam Sanobar , Madkaikar Adwait
Published: August 2024

The global transition from fossil fuels to clean energy is driven by the need to reduce carbon emissions and combat climate change. However, this transition has its own set of costs, benefits, and concerns. The top-down approach to the transition often fails to consider the social, economic, and environmental costs associated with it, leading to conflicts among stakeholders and social groups. The transition to net-zero emissions will increase job opportunities, but it also poses a risk of job loss and displacement, particularly in industries reliant on coal. The chapter explores the challenges and opportunities of the energy transition, in the Indian context, and the unequal distribution of resources among different regions and social groups. It adopts a three-pronged approach: an extensive literature review, a detailed case study, and stakeholder consultations. The chapter aims to offer actionable insights for policymakers, industry stakeholders, and communities to navigate the challenges, concerns, and opportunities of the ongoing energy transition towards a cleaner future.
Does Financial Knowledge Decline With Age?
Authors: Álvarez-Espiño Marcos , Fernández-López Sara , Rey-Ares Lucía , Almeida Fernando Luís
Published: August 2024

Small enterprises (SEs) represent the majority of the businesses worldwide, playing a leading role in job creation and economic development. The success of these firms substantially depends on the financial knowledge of their owners/managers. Previous literature in the field of household finances has indicated that financial literacy declines as individual ages. However, the scarce literature on entrepreneurs' financial literacy has not addressed this issue. Using a sample of 896 SE owners/managers, drawn from the survey of small enterprises' financial literacy in Spain, the authors observe a decline in objective financial knowledge with age through multivariate analyses using probit and ordered probit models. The lack of financial knowledge may put at risk the economic feasibility of an SE. Therefore, it is essential to design financial education mechanisms that are sensitive to the needs of SE owners/managers at different stages of their working lives.

Published: August 2024

The cultural standards favours men in business, relegating women to more domestic roles in northern Nigeria. Recently, a substantial shift has arisen as mumpreneurs, or mothers who also run Islamic medicine businesses, have begun to take control in the sector. In this connection, this chapter explores the contribution of mumpreneurs in the Islamic medicine industry within the context of northern Nigeria by investigating their motivations, prospects, and challenges. By employing qualitative techniques through observation and interviews, five mothers were purposefully selected and interviewed. The findings show that social and economic factors such as marriage status, unemployment, financial difficulties, the desire for personal growth, and independence motivate them to engage in this business, and they effectively address medical problems and create employment opportunities. Yet, they encounter challenges such as social stigma, gender discrimination, and traditionalist criticism. The chapter recommends that mumpreneurs promote the practice through modern innovations, and techniques.

Waist-based anthropometric measures and central adiposity-related comorbidities in children
Authors: Gomwe Howard , Phiri Lesego , Marange Chioneso S.
Published: August 2024

Background: Waist-related measures are commonly used to classify central adiposity and related comorbidities. This classification may be essential among children, as it may identify the risk of future non-communicable diseases.Methods: A cross-sectional study was conducted in the Eastern Cape province, South Africa, among 459 primary school learners aged 9–14 years. Height, weight and waist circumference (WC) were measured using standardised techniques recommended by World Health Organization (WHO). The anthropometric measurements, including body mass index (BMI), WC, waist-to-hip ratio (WHR) and waist-to-height ratio (WHtR) were computed and evaluated.Results: Most participants were girls (57.70%) with an average age of 11.20 ± 1.60 years. The average weight was 38.81 kg ± 10.49 kg with an average height of 144.16 (standard deviation [s.d.] = 10.37) cm. The sample had a BMI of 18.41 kg/m2 (s.d. = 3.19). The results showed, on average, WC of 62.10 cm ± 8.12 cm, WHR of 0.82 ± 0.15 and WHtR of 0.44 ± 0.05. Girls reported significantly higher BMI, WC and WHtR. Based on WHtR, the results showed the acceptable ability to classify children according to abdominal obesity, thus identifying their risk for comorbidities.Conclusion: Overall body fat indicated by BMI and central obesity shown by waist-related anthropometric measures can play a significant role in classifying children in terms of their risk of comorbidities.Contribution: To prevent the risks of metabolic diseases in childhood, it is necessary to detect abdominal obesity early using WC-based anthropometric measurements, especially WHtR, to identify those at risk.

Mouse spermatogenesis entails the maintenance and self-renewal of spermatogonial stem cells (SSCs), which require a complex web-like signaling network transduced by various cytokines. Although brain-derived neurotrophic factor (BDNF) is expressed in Sertoli cells in the testis, and its receptor tropomyosin receptor kinase B (TrkB) is expressed in the spermatogonial population containing SSCs, potential functions of BDNF for spermatogenesis have not been uncovered. Here, we generate BDNF conditional knockout mice and find that BDNF is dispensable for in vivo spermatogenesis and fertility. However, in vitro, we reveal that BDNF-deficient germline stem cells (GSCs) exhibit growth potential not only in the absence of glial cell line-derived neurotrophic factor (GDNF), a master regulator for GSC proliferation, but also in the absence of other factors, including epidermal growth factor (EGF), basic fibroblast growth factor (bFGF), and insulin. GSCs grown without these factors are prone to differentiation, yet they maintain expression of promyelocytic leukemia zinc finger (Plzf), an undifferentiated spermatogonial marker. Inhibition of phosphoinositide 3-kinase (PI3K), mitogen-activated protein kinase (MAPK)/extracellular signal-regulated kinase (ERK), and Src pathways all interfere with the growth of BDNF-deficient GSCs. Thus, our findings suggest a role for BDNF in maintaining the undifferentiated state of spermatogonia, particularly in situations where there is a shortage of growth factors.

Depression currently affects about 280 million people worldwide and its prevalence has been increasing dramatically, especially among the young and people of reproductive age, which consequently leads to an increase in antidepressant consumption. Antidepressants are associated with sexual dysfunction in both men and women; however, their role in male fertility has been scarcely studied. Fluoxetine and sertraline, two serotonin reuptake inhibitors (SSRIs), are among the most prescribed antidepressants worldwide. To determine their possible effects, human sperm cells were exposed to either sertraline or fluoxetine at concentrations previously found in blood and seminal fluid of patients undergoing treatment. Spermatozoa were incubated for up to 24 h at 37°C and 5% CO2, and important functional parameters such as sperm motility, viability, mitochondrial membrane potential, cellular reactive oxygen species (ROS) production, chromatin/DNA integrity, acrosome status, and tyrosine phosphorylation were assessed. At low levels, fluoxetine consistently decreased progressive motility throughout time while promoting fluctuations in ROS levels and sperm capacitation. Nevertheless, it did not affect viability, mitochondrial membrane potential, acrosome reaction nor chromatin/DNA integrity. Sertraline, on the other hand, had little to nonsignificant impact at low doses, but affected almost all tested parameters at supratherapeutic concentrations. Altogether, our results suggest that both antidepressants may impair sperm function, possibly through different mechanisms of action, but fluoxetine is the only exhibiting mild negative effects at doses found in vivo.

ABSTRACT

Objective:

This retrospective study aimed to determine the effect of liraglutide on weight and HbA1c levels in patients with type 2 diabetes mellitus (T2DM) in Saudi Arabia. The present investigation was carried out at a medical facility located in the Kingdom of Saudi Arabia.

Materials and Methods:

A retrospective analysis was conducted on the clinical records of 290 patients who were diagnosed with T2DM and were above 18 years of age. These patients were administered liraglutide for a minimum of 6 months. The dataset comprised various parameters such as the duration of diabetes, duration of liraglutide therapy, weight, and multiple biochemical markers such as HbA1c and low-density lipoprotein cholesterol levels. These parameters were measured both before and after the administration of liraglutide therapy.

Results:

The primary metrics evaluated in this study were alterations in body weight and levels of glycated hemoglobin (HbA1c). Over the 24-month observational period, significant reductions in body mass index (38.6 kg/m2 to 37 kg/m2), body weight (99.3 kg to 96 kg), and HbA1c levels (8.9% to 7.8%) (all P < 0.01) were seen.

Conclusion:

Liraglutide reduced HbA1c levels and weight and affected multiple metabolic markers in patients with T2DM in a real-world setting in Saudi Arabia.
Enhanced Thermal Management in Oil Spray-Cooled Motors: A Novel
Approach to Replacing NTC Sensors
Authors: Lu Junjie , Li Qiang , Chen Binglin , Zhu Lunzhi , Wu Jian , Yan Pingtao
Published: August 2024

Motor temperature plays a critical role in controlling pump speed and regulating
coolant flow to prevent overheating during motor operation. Presently, negative
temperature coefficient (NTC) sensors are commonly used for motor temperature
measurement, typically installed at the motor winding’s end for ease of
installation. However, in oil spray-cooled motors, the temperature distribution
is uneven due to the spray pipe, leading to lower temperatures near the pipe
compared to other areas. This results in a challenge where relying solely on NTC
measurements at the winding end may not meet the motor’s cooling requirements.
To address this issue and improve temperature signal accuracy, a novel approach
has been developed that utilizes four signals derived from the motor controller:
motor speed, motor torque, along with oil pump speed, oil temperature. Employing
the lumped parameter method, a model established in Simulink aims to estimate
the average temperature in the motor’s high-temperature region. Subsequently,
this value is corrected and directly utilized as an input signal for motor
thermal management. The proposed approach not only enhances motor temperature
monitoring accuracy but also mitigates operational risks, thereby prolonging
motor lifespan and enhancing its overall safety.

Nghiên cứu này mở rộng cách tiếp cận Tài Chính Toàn Diện (TCTD) truyền thống bằng việc xây dựng thang đo tài chính toàn diện dựa trên cấu trúc các sản phẩm và dịch vụ hiện phổ biến tại Việt Nam thông qua hai chỉ số TCTD về ngân hàng và TCTD về mobile money. Tiếp đến, nghiên cứu xem xét các yếu tố tác động đến mức độ tài chính toàn diện của các cá nhân tại Việt Nam. Nghiên cứu sử dụng dữ liệu khảo sát 1,000 cá nhân tại Việt Nam năm 2022. Kết quả hồi quy của các yếu tố nhân khẩu học chỉ ra rằng các cá nhân có trình độ học vấn cao, thu nhập cao và đang tham gia lực lượng lao động có xu hướng sử dụng sản phẩm và dịch vụ tài chính ngân hàng và mobile money nhiều hơn, mức độ tài chính toàn diện của nhóm đối tượng này cũng cao hơn. Bên cạnh các yếu tố nhân khẩu học cơ bản, các kết quả hồi quy mở rộng chỉ ra rằng việc sinh sống ở thành thị hay nông thôn không tác động đến TCTD về ngân hàng. Tuy nhiên, đối với mức độ TCTD về mobile money, việc sinh sống ở thành thị có tương quan dương với việc sử dụng mobile money. Trên cơ sở các bằng chứng thực nghiệm, nghiên cứu đề xuất một số kiến nghị nhằm nâng cao mức độ tài chính toàn diện cho cá nhân.

Authors: Furner Joseph M.
Published: August 2024

This paper will provide several examples of science and mathematics integration: navigation/map-reading, ecology/ecosystems/population growth, and chemistry/molecular structures. This paper underscores integrating STEM subjects with problem-based learning with technology such as video/computer simulations/programming/coding and the dynamic free online software GeoGebra. The paper suggests some GeoGebra-based connections to the science and math that is taught and a way to connect the disciplines with technology. Science involves and uses mathematics, and both subjects involve problem solving, and math is the tool that science uses. Subsequently, integrating science and mathematics using problem-based learning with technology might be a way to improve science and mathematics instruction while building confidence for STEM. Recommendations for STEM teachers are made along with some GeoGebra illustrations.
