We emphasize the importance of studying the primate brain in cognitive neuroscience and suggest a new mind-set in primate experimentation within the boundaries of animal welfare regulations.Specifically,we list the advantages of investigating both genes and neural mechanisms and processes in the emergence of behavioral and cognitive functions,and propose the establishment of an open field of primate research.The latter may be conducted by implementing and harmonizing experimental practices with ethical guidelines that regulate(1)management of natural parks with free-moving populations of target nonhuman primates,(2)establishment of indoor-outdoor labs for both system genetics and neuroscience investigations,and(3)hotel space and technologies which remotely collect and dislocate information regarding primates geographically located elsewhere. 展开更多

A new approach is demonstrated in which soft experimentation can be performed for MMP measurements, thus replacing the common practice of slim tube displacement laboratory experiments. Recovery potential from oil reservoirs by miscible flue gas injection was studied by slim tube and field-scale numerical simulation using two flue gases and seven crude oils sampled at different depths in three candidate reservoirs. The soft experimentations were conducted using Eclipse300TM, a three-phase compositional simulator. This study investigates minimum miscibility pressure (MMP), a significant miscible gas injection project screening tool. Successful design of the project is contingent to the accurate determination of the MMP. This study evaluates effects of important factors such as injection pressure, oil component composition, and injection gas composition on the MMP and recovery efficiency for slim tube and field-scale displacements. Two applicable MMP correlations were used for comparison and validation purposes. 展开更多

Objective： The aim of this project was to train highly professional and specialized nursing students from medical colleges to adapt to bedside clinical care by exploring and discussing various methods of injection and IV infusion in animal experimentation to hone the core professional nursing competencies. Methods： Two classes from the 2012 senior graduating nursing class were randomly selected by a computer to conduct the diversified practical teaching methods based on animal experimentation. A hospital environment was simulated by requiring students to perform different types of injections and practical IV infusion techniques. A comprehensive evaluation of the core professional competencies, as well as other integrated competencies, was conducted to determine the effectiveness of the teaching methods. Results： Two-sampled, pairwise u-tests were performed between the scores of the experimental （nursing class 2） and control （nursing class 1） groups. These findings showed that the overall test scores were significantly higher in the experimental group compared to the control group and that the average P-values for the competencies in various categories were 〈0.01, which indicated statistically significant results. Conclusions： Based on the data from this project, diversified teaching methods for basic nursing training founded on animal experimentation can help nursing students perfect their core professional competencies and improve their overall professional standing. The introduction of animal experimentation requires further verification, and an increased acknowledgement of its benefits through the widespread dissemination of this information. 展开更多

This study was carried out at the Mamou Higher Institute of Technology during the period from March 10 to April 15, 2022, with the aim of designing and testing a solar dryer with forced convection by drying potatoes. The dryer was designed using local materials. Its main geometric parameters are: 1) height of the drying chamber (90 cm), 2) length of the drying chamber (50 cm), 3) width of the drying chamber (43 cm), 4) surface of the racks (0.1806 m2), 5) surface of the heat accumulator (0.2537 m2). The experiment focused on the vacuum test of the dryer for two days and that of the drying of the sweet potato for three days from 8:30 a.m. to 5:30 p.m. The average vacuum test temperature values of the three environments are respectively accumulator (43°C), dryer chamber (41°C) and ambient environment (34°C). Four kilograms (4 kg) of boiled sweet potato were dried. The average temperatures in the accumulator and in the drying chamber during the three days of drying are respectively 33°C and 39°C. The final mass of the dried product is 1.2 kg, with a quantity of water extracted of 2 liters or 63% of the initial mass of the product. The average drying rate is 0.074 kg/h. The drying kinetics showed a decreasing rate in the absence of the heating period and the constant rate period. 展开更多

Background: The Tiêu equation has a ground roots approach to the process of Quantum Biology and goes deeper through the incorporation of Quantum Mechanics. The process can be measured in plant, animal, and human usage through a variety of experimental or testing forms. Animal studies were conducted for which, in the first day of the study all the animals consistently gained dramatic weight, even as a toxic substance was introduced as described in the introduction of the paper to harm animal subjects which induced weight loss through toxicity. Tests can be made by incorporating blood report results. Human patients were also observed to show improvement to their health as administration of the substance was introduced to the biological mechanism and plants were initially exposed to the substance to observe results. This is consistent with the Tiêu equation which provides that wave function is created as the introduction of the substance to the biological mechanism which supports Quantum Mechanics. The Tiêu equation demonstrates that Quantum Mechanics moves a particle by temperature producing energy thru the blood-brain barrier for example. Methods: The methods for the Tiêu equation incorporate animal studies to include the substance administered through laboratory standards using Good Laboratory Practices under Title 40 C.F.R. § 158. Human patients were treated with the substance by medical professionals who are experts in their field and have knowledge to the response of patients. Plant applications were acquired for observation and guidance of ongoing experiments of animals’ representative for the biologics mechanism. Results: The animal studies along with patient blood testing results have been an impressive line that has followed the Tiêu equation to consistently show improvement in the introduction of the innovation to biologic mechanisms. The mechanism responds to the substance by producing energy to the mechanism with efficient effect. For plant observations, plant organisms responded, and were seen as showing improvement thru visual observation. 展开更多

The study of personality has always been presented in Psychology as a way to understand the individual＇s behavior and characteristics. Within such context, several theorists deepened their studies and used techniques to reveal the psychical world structure. By attempting to know the individual in their characterological profile, the psychologist and educator Helena Antipoff decided to revive her experience in the former Soviet Union by means of the observation models developed by the psychologist and psychiatrist Lazursky. When Antipoff arrived in Brazil in 1929, invited by the government to assist in the development of the educational reform in the period called New School, she started to spread Lazursky＇s work in the state of Minas Gerais. Antipoff used Lazursky＇s Natural Experimentation rather than intelligence tests in psychological evaluations as a method aimed at the characterization of personality through observations of the behaviors and routine under natural conditions. She researched about individuals by using systematized and standardized observations and experiments, whose results were analyzed methodologically in figure and tables, which helped her study the personality of both the students and teachers. The purpose of this paper is to show, based on primary source documents from Antipoff＇s publications between 1930＇s and 1950＇s, the study of the personality through the Natural Experimentation method as the main model for the beginning of her educational work in Brazil. The use of the method contributed to the new educational structure, once it consisted of investigating and evaluating the student according to his profile, that is, his personality. 展开更多

Building China’s independent knowledge system in education has become a new mission for contemporary educational scholars. Over the past century, Chinese education, as a result of the eastward spread of Western learning, has promoted educational development. However, it has simultaneously led to intellectual ossification in building China’s independent knowledge system, diminished China’s international discourse power in education, and diluted confidence in China’s own education and culture, thereby falling into a dilemma of academic dependency. To empower the building of China’s independent knowledge system in education through educational experimentation, it is essential to take root in Chinese reality, focus on the positivist paradigm, and value practice. To build China’s independent knowledge system in education, it is necessary for the researchers to ground themselves in fine traditional Chinese culture, transitioning from bringing in by drawing on foreign theories to going global through dialogue with the world. It is necessary to be guided by the spirit of educators, enhancing awareness that equally values practical action and academic research, thereby injecting new dynamics in building independent knowledge system. Additionally, educational experimentation is advised to be utilized as the operational mechanism, sublimating reflective theories from actions to form formidable forces empowering the building of China’s independent knowledge system in education. 展开更多

This paper presents the work implemented in designing, fabricating and operating a model of a cheap hydraulic DDM （deep drawing machine）, which is currently utilized in the manufacturing processes lab in the IED （Industrial Engineering Department） at An-Najah National University. The machine is used to conduct different experiments related to the deep drawing process. This work was implemented in three stages： the first was the design stage, in which all design calculations of the DDM elements were completed based on the specifications of the product （cup） to be drawn; the second was the construction stage, in which the DDM elements were fabricated and assembled at the engineering workshops of the university; the last was the operating and experimentation stage, in which the DDM was tested by conducting different experiments. The experience gained from designing and constructing such a mechanical lab equipment was found to be successful in terms of obtaining practical results that agree with those available in literature, cost-effective relative to the cost of a similar purchased equipment, as well as enhancing students＇ abilities in understanding the deep drawing process in particular and machine elements design concepts in general. 展开更多

Herein,we report a novel and highly efficient method for the synthesis ofα-phosphoryloxy carbonyl compounds via Rucatalyzed P(O)O–H insertion reactions of sulfoxonium ylides and phosphinic acids,with the assistance of high-throughput experimentation(HTE)and machine learning(ML).A variety of P(O)O−H derivatives,including diarylphosphates,alkyl phosphates,and alkoxyphosphates,are competent candidates to react with sulfoxonium ylides in this transformation,and variousα-phosphoryloxy carbonyls and propylene phosphates are directly constructed.This approach utilizes readily available sulfoxonium ylide as a carbene precursor,and features mild conditions,operational simplicity,and broad functional groups tolerance,and could be used for late-stage functionalization of structurally complex bioactive molecules.Moreover,a conducive exploration of the reaction space is also conducted(756 reactions)and a machine learning model for reaction yield prediction has been developed and applied,showcasing the practical application of this newly workflow(HTE-ML)in the field of synthetic chemistry. 展开更多

Accurately assessing the impact of turbulence structures on load fluctuation is crucial for the long-term stable operation of wind turbines.Based on turbulence signals observed at the Qingtu Lake Observed Array in China,the aerodynamic load responses of the wind turbine to different turbulence scales are quantitatively analyzed in this study.The results indicate that very large-scale motions(VLSMs)are associated with significant load fluctuations due to its low frequency and high energy characteristics,increasing the risk of extreme loads.Large-scale motions coupled with the natural frequency of wind turbines in the medium frequency range,result in resonance phenomena.Small-scale motions,due to their high-frequency rapid vibration characteristics,cause instantaneous oscillations in wind turbine loads.Furthermore,correlation analysis indicates that the flapwise moment and thrust are most sensitive to VLSMs,while the edgewise moment is less affected by the scale characteristics.It is worth noting that this study is the first to explore the modulation effects of different scales of turbulent structures on the amplitude of wind turbine load fluctuation.It was found that turbulent structures exceeding a scale of 3δ have the most significant impact on modulating the load amplitudes,where δ is the boundary layer thickness,which is 99% of the flow velocity outside the boundary layer.These findings contribute to the enhancement of understanding regarding the load response of wind turbines in multi-scale turbulent environments and provide important references for the optimization of wind turbine design and load control. 展开更多

In this paper,we report a recent experimental study of streak structures in the turbulent separated shear flow by datadriven deep neural network.By applying spanwise-aligned tetrahedron vortex generators upstream of a plane backward-facing step,spanwise-aligned high-and low-speed streaks were generated within the separated shear layer behind the step.The velocity profiles of the shear flow were measured by single-probe hot-wire anemometer in both the streamwise-vertical and the streamwise-spanwise planes in the wind tunnel.Deep neural network models are trained and verified based on the experimental datasets.The input parameter sets include the vortex generator height,spanwise spacing,and the spatial coordinates within the measurement domain,while the output parameter sets are mean and root-mean-square velocities of the shear flow.Mean squared errors between the model-predicted and experimentally measured data are used for quality evaluation of different deep neural network model designs,among which the minimum error of the optimal design descends less than 1%.For other vortex generator parameters,which are not measured in the wind tunnel or used in the training,the model prediction provides reasonable mean velocity contours with streak structures.Thus,we find that the experimental data-driven modeling approach shows reliable robustness for nonlinear fitting of complex datasets as well as considerable generalization for turbulent coherent structures. 展开更多

The dynamic characteristics of the track system can directly affect its service performance and failure process.To explore the load characteristics and dynamic response of the track system under the dynamic loads from the rack vehicle in traction conditions,a systematic test of the track subsystem was carried out on a large-slope test line.In the test,the bending stress of the rack teeth,the wheel-rail forces,and the acceleration of crucial components in the track system were measured.Subsequently,a detailed analysis was conducted on the tested signals of the rack railway track system in the time domain and the time-frequency domains.The test results indicate that the traction force significantly affects the rack tooth bending stress and the wheel-rail forces.The vibrations of the track system under the traction conditions are mainly caused by the impacts generated from the gear-rack engagement,which are then transferred to the sleepers,the rails,and the ballast beds.Furthermore,both the maximum stress on the racks and the wheel-rail forces measured on the rails remain below their allowable values.This experimental study evaluates the load characteristics and reveals the vibration characteristics of the rack railway track system under the vehicle’s ultimate load,which is very important for the load-strengthening design of the key components such as racks and the vibration and noise reduction of the track system. 展开更多

Characterizing shale oil reservoirs encompassing pore space,mineralogy,and fluids is fundamental to effective exploration and development.Recent advances in experimental techniques have significantly improved both the qualitative and quantitative analysis of these components;however,a comprehensive systematic review is lacking.High-resolution imaging technologies,such as Scanning Electron Microscopy(SEM),Field Emission Scanning Electron Microscopy(FE-SEM),and Focused Ion Beam Scanning Electron Microscopy(FIB-SEM),enable detailed visualization of pore structures.Gas adsorption and high-pressure mercury intrusion methods provide accurate pore-scale quantification.Moreover,techniques like X-ray Diffraction(XRD),X-ray Fluorescence Spectroscopy(XRF),and Electron Probe Microanalysis(EPMA)allow precise mineral identification and compositional analysis.Confocal Scanning Laser Microscopy(CSLM),Raman Spectroscopy,Nuclear Magnetic Resonance(NMR),and Rock Pyrolysis provide insights into fluid occurrence and content within shale reservoirs.Based on a comprehensive review of existing research,this study identifies several key future directions:(1)addressing the challenges of nanopore observation in reservoir space characterization while minimizing the impact of sample preparation on pore structure;(2)improving the accuracy of quantitative mineral analysis and developing advanced new technologies for the precise measurement of complex mineral compositions;(3)enhancing the fluid quantitative evaluation of fluids by more effectively restoring subsurface geological conditions.This paper presents a current synthesis and forward-looking perspective on experimental techniques supporting shale oil exploration,aiming to guide future research and technological innovation in this field. 展开更多

The design of floating wind turbines(FWTs)requires comprehensive consideration of complex marine environments and coupled responses among various components.The efficiency of current time domain simulation methods remains insufficient for design and optimization in the early stages of FWT development.This study validates a proposed frequency domain(FD)modeling method through code-to-experiment comparison.The FD method incorporates fundamental assumptions about the FWT model,including representing the FWT tower as a nonlinear beam and modeling the rotor-nacelle assembly(RNA)and floating platform as rigid bodies positioned at each end of the tower.The method incorporates excitation loads using blade element momentum theory,linear potential flow theory,and quasistatic catenary theory for aerodynamic,hydrodynamic,and mooring dynamics,respectively.Validation involves a code-to-experiment comparison through a basin model test utilizing a 1/50 scaled semi-submersible platform equipped with a 5MW wind turbine.The results demonstrate strong correlation with experimental data regarding mean response and power spectral density of platform and nacelle motions.The overall discrepancy for these physical quantities remains below 10%.Specifically,the mean discrepancy of platform surge and pitch motions under combined wind and wave conditions measures 1.05%and 3.91%,respectively.This validation confirms the viability of the proposed FD method,offering substantial technical support for early-phase analysis and optimization of FWT.The validation results contribute significantly to advancing FWT design and optimization understanding. 展开更多

The native thelytokous(TH)and arrhenotokous(AR)strains of Neochrysocharis formosa(Westwood)(Hymenoptera:Eulophidae)are promising biocontrol agents against the invasive tomato pest Tuta absoluta(Meyrick)(Lepidoptera:Gelechiidae).This study assessed the performance and preferences of these strains in choice experiments involving five host instar ratios and evaluated their functional responses to seven densities of 1st instar larvae(5 to 40 hosts).In host-attacking behavior assays,an increasing proportion of 1st instar larvae led to a significant rise in host mortality rates for both strains.Both strains exhibited strong preferences for parasitizing and attacking 1st instar larvae over later instars,with the TH strain demonstrating significantly greater host-killing efficacy than the AR strain.Functional response experiments revealed that the attack rates of both strains were positively correlated with host density.Parasitism by both strains and host-stinging behavior by the TH strain showed type Ⅲ functional responses,while host-feeding by both strains and host-stinging by the AR strain followed type Ⅱ functional responses.Early establishment of the TH strain in tomato agroecosystems could enhance the management of T.absoluta.These findings provide critical insights into the functional dynamics of the TH and AR strains of N.formosa that can inform the development of effective biocontrol programs for this globally significant pest. 展开更多

With the increasing duration of space missions,the impact of fungi on aerospace materials requires systematic investigation.We evaluate the adaptability of Aspergillus brasiliensis and its corrosion effects on aluminum alloy under space conditions through a 90-day experiment.Fungal growth characteristics,ultrastructural changes,metabolic activity,and interactions with the material surface are analyzed.The results show that Aspergillus brasiliensis maintains high adaptability to microgravity,exhibiting thickened cell walls,enhanced spore formation,and increased metabolic activity.Corrosion analysis reveals that fungal attachment accelerates localized material degradation through organic acid secretion and oxygen concentration differentials.The microgravity environment further amplifies these effects by influencing fungal metabolism and altering corrosion dynamics.Compared to ground-based conditions,space-exposed samples show significantly higher organic acid concentrations and metal ion dissolution,indicating intensified corrosion.These findings enhance the understanding of microbial corrosion mechanisms in space and provide a foundation for antifungal strategies to improve the reliability of aerospace materials during long-term missions. 展开更多

Heavy-ion collisions(HICs)is a unique experimental tool for investigating the properties of nuclear matter under extreme conditions in the laboratory.At HIRFL-CSR energies,HICs can create nuclear matter with 2-3 times the saturation density(ρ0).The HIRFL-CSR external-target experiment(CEE)is a large-acceptance spectrometer designed to explore frontier topics in high-energy nuclear physics,such as the QCD phase structure and nuclear matter equation of states.In this letter,we introduce simulation and analysis software for the CEE experiment(CeeROOT).Based on the CEE conceptual design and CeeROOT software,the configurations of its subdetectors were optimized by considering foreseeable physical constraints.The final detector layout of the CEE spectrometer and its acceptances were validated through simulations of U+U collisions at 500 MeV/u and pp collisions at 2.8 GeV,which demonstrated that the CEE experiment will serve as a detector with wide acceptance and multi-particle identification capabilities for studying high-energy nuclear physics topics at HIRFL-CSR energies with pp,pA,and A A collisions. 展开更多

Current research focuses on analyzing the melting mechanism of scrap in laboratory settings,with limited reports on scrap melting within actual converter blowing environments.A three-dimensional full-scale converter mathematical model coupling turbulent,multiphase,heat transfer,and mass transfer was established to examine the melting behavior of scrap with varying initial weight and carbon concentration in a combined blowing converter.And,the mathematical model was verified by a water model experiment and a thermal experiment.The results showed that the time required for complete melting of 100 kg scrap was 495 s,exceeding that of 150 and 200 kg scrap by 105 and 30 s,respectively,due to changes in the specific surface area of scrap during the melting process.The melting time for scrap with a carbon concentration of 0.612 wt.%is notably shorter at 465 s compared to 1575 s for 0.326 wt.%carbon concentration and 2475 s for 0.183 wt.%carbon concentration.Additionally,secondary solidification occurs during the melting of low-carbon steel and medium-carbon steel.For scrap with a carbon concentration of 0.612 wt.%,the carburizing time was 134 s,significantly lower than 300 s for 0.326 wt.%carbon concentration and 445 s for 0.183 wt.%carbon concentration,respectively. 展开更多
