Authors: Munir Khadija , Umar Arif Iqbal , Yousaf Waqas
Published: March 2023

Fruit classification is playing a vital role in robot-based farming. The plucking of fruits and packing is done using robots nowadays. This could only be possible using efficiently trained robots base on machine learning. Different techniques have been developed for fruit classification, but still, there are many gaps, i.e., efficiency and accuracy. In this research work, we are targeting classification accuracy. This paper presented an Automatic Fruit Detection tool with good precision and recalled using deep learning neural networks. It will help in farming, cultivation, and produce sound effects in robotic farming. The aim is to build an accurate, fast and reliable fruit detection system, a vital element of an autonomous agricultural robotic platform; it is a crucial element for fruit yield estimation and automated harvesting. We used the ResNet-50 in the context of transfer learning. Different training choices were defined, i.e., 10% to 80%. Experimental results show that we compete for the prior approaches even on only 10% training. The proposed approach achieves state-of-the-art results compared to prior work with the F1 Score, which considers both precision and recall performances improving from 0.838 to 0.894 and 0.995 of accuracy. In addition to improved accuracy, this approach is also much quicker as compared to recent approaches.

Published: March 2023

This research aims to study the variation in properties of hot-rolled SAE 1006 IF steel sheets during cold rolling to reveal the factors causing the decrease in formability of SPCG steel sheets during deep drawing. Results have shown that pickling does not affect the mechanical properties; however, cold rolling results in an increase in hardness, tensile strength and yield strength. Stress relieve annealing results in coarsening and homogenizing of grains which reduces brittleness and impart ductility. Temper rolling causes an increment in mechanical parameters again, improve surface hardness and flatness. By analyzing the microstructure and comparing it with the HESCO sample, it is revealed that there are still some elongated grains found along with coarse grains after annealing. Soaking time is not sufficient for the growth of homogenized structure, resulting in decreased ductility and formability during deep drawing.

Published: March 2023

In the diversification of the world's energy portfolio, microalgae biofuels have gained particular attention as a means of providing carbon-neutral hydrocarbon-based fuels. The progress on this front has been hindered because of expensive and unreliable microalgae cultivation systems, where the preparation of synthetic culture media poses a monetary strain. This study aims to investigate a new microalgae growth media that is readily available and cost-effective. The new microalgae fertilizerbased media (FBM) were designed and compared with Bold Basal media (BBM) in terms of growth parameters, production of lipid and value-added algal by-products (carotenoid and phycobiliprotein). The growth parameters such as cell count and specific growth rate were investigated for FBM and BBM. FBM showed a significant growth rate of 7 million/mL-per day as compared to 2 million/ml per day. A similar growth trend was observed for chlorophyll (a), (b) and carotenes which increased to the values of 5microgram/gram formula weight (µg/gfw), 3 µg/gfw and 2 µg/gfw for FBM. On the other hand, lipid and phycobiliprotein showed a decrease of 18.75 % and 16.66 %, respectively, compared to BBM. Even though some growth parameters are negatively affected by fertilizer-based media, the cost reduction is substantial to allow this drawback to be overlooked. The medium's cost is reduced by a factor of 7 and provides ground for the use of the FBM in the large-scale cultivation of algae for biomass production.

Published: March 2023

Clean coal technology (CCT) is an environmentally friendly technology for producing syngas. The gasification process is part of CCT for producing the syngas. The numerical simulation of the gasification process is much more economical compared to the experimental study. So, it is beneficial for calculating syngas composition and helping to improve the gasification process. In the present research, the single-stage entrained gasifier is considered for the syngas composition analysis. In the study, the volatile break-up was estimated by the finite volume method. The reaction rates are analyzed using the Finite rate dissipation reaction model. The syngas composition and the exit temperature result of simulation follow behavior reported in the literature.

Published: March 2023

Due to high biocompatibility, bioactivity, and natural occurrence in bones and teeth, synthetic calcium hydroxyapatite (CaHAp) is a widely applied biomaterial in tissue engineering, including orthopedic surgery and dentistry. However, the brittle nature and low strength reduce its durability, which can be improved by doping metal ions. Rubidium (Rb) is an essential trace element that works as an antibacterial agent in the human body; therefore, it can be doped in synthetic Ca-HAp to promote its durability. In this work, Rb-doped calcium hydroxyapatite (Rb-HAp) nanoparticles are synthesized by the coprecipitation method at low temperatures. Phase purity, crystallinity, doping level, and mechanical properties are investigated by X-ray diffraction (XRD), inductively coupled plasma optical emission spectroscopy (ICP-OES), and micro-hardness tester. It is observed that a minute quantity (≈ 0.02%) of Rb remained in the apatite structure when 5% of Rb+ is doped via in situ method. Moreover, small dopant concentration did not affect the crystal structure and the tensile strength of HAp.
Synergy Estimation Method for Simultaneous Activation of Multiple DOFs Using Surface EMG Signals
Authors: Bahadur Rabya , Saeed ur Rehman  , Rasool Ghulam , Khan Muhammad AU
Published: March 2023

Surface electromyography signals are routinely used for designing prosthetic control systems. The concept of synergy estimation for muscle control interpretation is being explored extensively. Synergies estimated for a single active degree of freedom (DoF) are found to be uncorrelated and provide better results when used for single movement classification; however, an increase of simultaneously active DoFs leads to complex limb movements and multiple DoF detection becomes a challenge. Synergy estimation is a non-convex optimization technique, to provide better estimation this paper proposes the use of regularized non-negative matrix factorization for the evaluation of synergistic weights in complex movements. The use of regularization constraint makes the overall problem bounded and provide smoothness. The proposed technique showed better accuracy when tested for activation of multiple DoF simultaneously at a significantly lower computational time, i.e., by 34%.

Published: March 2023

The characterization of the gas condensate reservoir is complicated due to the multiphase flow of the fluid. The change of the composition of the excellent stream further makes it complicated. Such characterization is being done to measure the superb performance. To overcome this complexity, rigorous mathematical modelling is suggested for well test analysis. This mathematical modelling can be used to establish the correlation between well test analysis and well performance analysis. The research work is carried out to develop the analytical method to calculate the effective permeability of the gas condensate reservoir, gas condensate mobility and effects of mobility on the effective permeability. Here the different mathematical models are studied during the research work. The other correlations are used to determine the reservoir fluid's properties. Perrine’s method is used to estimate reservoir permeability. The research was carried out to analyze the effects of gas condensate mobility on permeability. In this work, the pressure build-up test data is analyzed, effective permeability ( ), gas condensate mobility and effects of gas condensate mobility are analyzed. This study found effective permeability and mobility by applying mathematical models, oil 14.603 mD, gas 0.148 mD and water 17.159 mD. Using the data obtained through the correlations, the calculated mobility (λ) of the oil, gas and water phase is 126.652 mD/cp, 13.454 mD/cp and 98.671 mD/cp, respectively.

Multiple-Sliding-Surface Guidance and Control for Terminal Atmospheric Reentry and Precise Landing
Authors: Vitiello Alessandro , Leonardi Edoardo Maria , Pontani Mauro
Published: March 2023

The development of an effective guidance and attitude control architecture for terminal descent and landing represents a crucial issue for the design of reusable vehicles capable of performing a safe atmospheric planetary entry. The sliding mode control represents a nonlinear technique able to generate an effective real-time closed-loop guidance law, even in the presence of challenging contingencies. This work proposes a multiple sliding-surface guidance control law that is able to drive a lifting vehicle toward safe landing conditions, associated with a desired downrange, crossrange, runway heading, and final vertical velocity at touchdown, even starting from challenging initial conditions. The time derivatives of the lift coefficient and the bank angle are used as the control inputs, whereas the sliding surfaces are defined so that these two inputs are involved simultaneously in the lateral and the vertical guidance. The commanded attitude is pursued by the attitude control system, which employs a feedback nonlinear control law that enjoys quasi-global stability properties. Effectiveness and accuracy of the guidance and control strategy at hand are proven numerically by means of a Monte Carlo campaign, in the presence of stochastic wind and large dispersions on the initial conditions.
The Epoch-State Filter, Revisited
Authors: Carpenter J. Russell
Published: March 2023

The epoch-state filter is a recursive sequential estimator that maintains its state estimate and associated covariance at a fixed time known as the epoch, avoiding the need to propagate the covariance between measurements. Instead, the filter maps measurement innovations from the measurement time to the epoch time, in a fashion similar to a batch estimator. When process noise is present, the epoch time must follow all but at most the penultimate measurement. Revisiting the topic, this paper contributes several variations, including a factorized form, a factorized information form, and sigma-point versions, and provides a number of clarifying illustrative examples.
Closed-Form Analytical Approach for Calculating Noise Contours of Directive Aircraft Noise Sources
Authors: Amargianitakis Daniel C. , Self Rodney H. , Synodinos Athanasios P. , Proença Anderson R. , Torija Martinez Antonio J.
Published: March 2023

This paper extends the simplified airport noise model Rapid Aviation Noise Evaluator (RANE) [Torija et al., Journal of the Acoustical Society of America, Vol. 141, No. 2, 2017, pp. 981–995], adding capability of including fully nonisotropic noise sources. This extended tool, RANE v2, is developed as a part of multidisciplinary acoustic assessment of novel aircraft, in order to produce ground contours around airports and helipads. Version 2 extends the capability of RANE to accommodate predictions of future air vehicles implementing propulsion systems solution with inherent directional properties. The model uses three-dimensional noise emission surfaces around a series of discretized segments that represent the aircraft flightpath. The main inputs are the sources’ sound power level, the distance from the flightpath at which a level is observed, and the source three-dimensional directivity. The directivity function may take analytical or numerical form, allowing for experimental data inputs. This paper demonstrates the use of spherical harmonics as a form of directivity function with a closed-form analytical solution for calculating the noise exposure contours. Results and comparison against the Federal Aviation Administration’s Aviation Environmental Design Tool module for helicopter community noise indicate that exposure contour coordinates can be estimated for high and low noise exposure levels. The incorporation of source directivity allows for the assessment of lateral attenuation, engine installation effects, and transition operations (for vertical to horizontal flight and vice versa) via the assumption of individual source directivities and, therefore, complex noise surfaces. As a consequence of the analytical nature of the model, low computational requirements allow for fast exploration of the design space and parametric studies, with minimal input requirements. The capabilities of RANE v2 are demonstrated by predicting noise footprints for three helicopters, each of different size, performance, and directivity characteristics.
Flow Reattachment on a NACA 0025 Airfoil Using an Array of Microblowers
Authors: Xu Kecheng , Lavoie Philippe , Sullivan Pierre
Published: March 2023

An array of commercially available synthetic jet actuators was developed for controlling flow separation on a NACA 0025 airfoil. The array is more compact in comparison to standard synthetic jet actuators previously studied for separation control. Wind tunnel experiments were conducted at chord Reynolds number [Formula: see text] and [Formula: see text]. Control of separation was applied by the array through forcing at the wake and shear layer frequencies ([Formula: see text] and [Formula: see text], respectively). Both effectively suppress flow separation, increase lift, and decrease drag. The dynamics of the reattached flow show different feature for the two forcing schemes. The results demonstrate that this array has comparable control effectiveness on separation to other synthetic jet actuators.

Gas-thermal spraying of self-fluxing, ceramic and other powder materials is one of the effective methods of restoring and strengthening machine parts. The paper describes the gas-thermal spraying methods. The reason for the appearance of macrodefects during mechanical processing in the form of microcracks and burns, and during the operation of parts -in the form of delamination of coatings, is the instability of the structure and physical and mechanical properties of coatings, as well as insufficient adhesive strength and significant residual stresses. In turn, the adhesion strength of coatings depends on the level of surface activation of the base material. The analysis of methods of activation of the surface of the part was performed. Different methods are used: shot blasting or sandblasting, spraying the sublayer, forming a "torn" cut. They all have different performance. The main factors that affect the adhesive and cohesive strength are the incomplete connection of the particles forming the coating, the structure of the coating and the residual internal stresses of the coating. The interaction of adhesion strength and residual internal stresses determines the workability of the coating. As the residual internal stresses increase, the adhesive strength decreases. One of the effective methods of reducing residual internal stresses in coatings is the action of ultrasonic vibrations. The paper presents the results of experimental studies of the influence of the amplitude of ultrasonicvibrations on the adhesionstrength of coatings. Adhesive strength was determined by the method of breaking off a conical pin. The authors gave a formula for calculating the adhesion strength of coatings. The analysis of the results of the experiment showed that the replacement of static grinding with vibration significantly increases (by 15-20%) the adhesive strength. This phenomenon is determined by the action of two factors: a decrease in the level of damage to the coating; reducing the yield point of the coating material. It should be noted that the possibility of such a transition is due to the reduction of the fragility criterion to values less than 1. The paper provides a formula for calculating the value of the fragility criterion of coatings, as well as a formula for calculating the length of a critical microcrack. Knowing the length of the critical microcrack makes it possible to diagnose coatings for their performance.

Fides Qua e Fides Quae no tornar-se cristão de Kierkegaard
Authors: Lopes Antonio Juliano Ferreira
Published: March 2023

The existential process inherent in becoming a Christian involves an escalation made up of ruptures, qualitative leaps and choices that directly reflect the existential stage in which the individual finds himself. If evolution within Christianity is possible, it is because it requires conscious action provoked by the decision that marks the transition between qualitative spheres. Both the aesthetic dimension and the ethical dimension of Christianity proved to be insufficient to lead Man to the rebirth inherent in becoming a Christian. Only the religious stage finds faith and only this mediates Christian becoming and the edifying construction of the self; therefore, it is necessary to understand the function of faith in this process and which faith it is about. It is necessary to establish the relationship between fides quae and fides qua, between the object of faith and the attitude of faith. According to the theological tradition, fides qua indicates the subjective act of believing, faith in its pure form, while fides quae indicates the object of belief, which in Christianity is identified with the content of revelation. The conversion of becoming a Christian would take place through the belief in the Christ in line with the relationship that subjectivity maintains with divine transcendence. To understand the correlation between fides qua and fides quae in Kierkegaardian philosophy is to understand what the Christianity idealized by the Danish author is about and to perceive the relationship between subjectivity and objectivity in the task of becoming a Christian.
A Interpretação Kantiana das Leis de Newton
Authors: Gomes Irio Vieira Coutinho Abreu
Published: March 2023

Our objective in this article is to show how the metaphysical foundation of Newton's three laws of motion by Kant takes place. Firstly, the place where Kant does this is not in the Critique of Pure Reason but in the Metaphysical Principles of Natural Science. Then, Kant does not find Newton's three laws like a derivation of his three analogies of experience. In fact, Kant finds his (and not Newton's) three laws of motion, which, after a due comparison, can be understood as another way of expressing Newton's laws. This is easy to defend when we note that Kant finds a law of conservation among the laws of motion, something totally alien to Newton's laws of motion. Thus, we manage to absolve Kant of the accusation of artificiality of his philosophy when taken as a system made in tow of Newton's physics.

Copper-catalyzed heterocyclic recombination of aziridine and diazetidine for the synthesis of imidazolidine
Authors: Higuchi Daiki , Matsubara Satoshi , Kadowaki Hiroki , Tanaka Daisuke , Murakami Kei
Published: March 2023

The discovery of new catalytic applications for metals remains an important goal in organic synthesis. If a catalyst has multiple functions, such as inducing bond cleavage and formation, it can streamline multi-step transformations. Herein, we report the Cu-catalyzed synthesis of imidazolidine through heterocyclic recombination between aziridine and diazetidine. Mechanistically, Cu catalyzes the conversion of diazetidine into the corresponding imine, which then reacts with aziridine to form imidazolidine. The scope is sufficiently wide to form various imidazolidines, as many functional groups are compatible with the reaction conditions.
Prediction of Redox Power for Photocatalysts: Synergistic Combination of DFT and Machine Learning
Authors: Fehér Péter Pál , Madarász Ádám , Stirling András
Published: March 2023

The accurate prediction of excited state properties is a key element of rational photocatalyst design. This involves the prediction of ground and excited state redox potentials, for which an accurate description of electronic structures is needed. Even with highly sophisticated computational approaches, however, a number of difficulties arise from the complexity of excited state redox potentials as they require the calculation of the corresponding ground state redox potentials and the estimation of the 0-0 transition energies (E0,0). In this study we have systematically evaluated the performance of DFT methods for these quantities on a set of 37 organic photocatalysts representing nine different chromophore scaffolds. We have found that the ground state redox potentials can be predicted with reasonable accuracy that can be further improved by rationally minimizing the systematic underestimations. The challenging part is to obtain E0,0 as calculating it directly is highly demanding and its accuracy depends strongly on the DFT functional employed. We have found that approximating E0,0 with appropriately scaled vertical absorption energies offers the best compromise between accuracy and computational effort. An even more accurate and cost-effective approach, however, is to predict E0,0 with machine learning and avoid the use of DFT for excited state calculations. Indeed, the best excited state redox potential predictions are achieved with the combination of M062X for ground state redox potentials and ML for E0,0. With this protocol the excited state redox potential windows of the photocatalyst frameworks could be adequately predicted. This shows the potential of combining DFT with ML in the computational design of photocatalysts with preferred photochemical properties.

Published: March 2023

Terpene cyclization, one of the most complex chemical reactions in nature, is generally catalyzed by two classes of terpene cyclases (TCs). Cytochrome P450s that act as unexpected TC-like enzymes are known but are very rare. Here, we genome-mined a cryptic bacterial terpenoid gene cluster, named ari, from the thermophilic actinomycete strain Amycolatopsis arida. By employing a heterologous production system, we isolated and characterized three highly oxidized eunicellane-derived diterpenoids, aridacins AC (13), that possess a rare 6/7/5-fused tricyclic scaffold. In vivo and in vitro experiments systematically established a non-canonical two-step biosynthetic pathway for diterpene skeleton formation. First, a class I TC (AriE) cyclizes geranylgeranyl diphosphate (GGPP) into a 6/10-fused bicyclic cis-eunicellane skeleton. Next, a cytochrome P450 (AriF) catalyzes cyclization of the eunicellane skeleton into the 6/7/5-fused tricyclic scaffold via C2-C6 bond formation. Quantum chemical computations support a hydrogen abstraction and subsequent oxidation mechanism for AriF catalyzed carbocation cyclization. The biosynthetic logic of skeleton construction in the aridacin diterpenoids is unprecedented, expanding the catalytic capacity and diversity of P450s and setting the stage to investigate the inherent principles of carbocation generation by P450s in the biosynthesis of terpenoids.

The most obvious problems in higher educational institutions are procrastination, academic dishonesty due to easy access to electronic resources, decreased attendance, and insufficient interaction between teachers and students.

Methodology: The research methodology is based on an empirical approach, which is a research survey using a questionnaire to collect data based on closed-ended questions. For quantitative analysis, the independent sample t-test was used. The survey was conducted among students and teachers of two educational institutions in the Russian Federation.

Contribution: This study is of practical and scientific importance as it can contribute to the introduction of virtual team building in the modern education system.

Findings: Based on the analysis of the data obtained, it can be concluded that students and teachers approximately equally assess the impact of team building on the ability to get to know each other better, improve communication skills, and psycho-emotional intimacy. Despite the need and sometimes no alternative to virtual team building (for example, during a pandemic), half of the sample of students (50.8%) agreed that team building was more effective in an offline environment while 64.3% of teachers believe that the effectiveness could have been higher in the offline environment. The respondents assessed the positive effect of team building on their interest and motivation to study or work.

Recommendations for Practitioners: These findings can contribute to a broader and faster implementation of virtual team-building practices in the education system of the Russian Federation and other countries of the world. The results of this study can be applied by higher educational institutions that are interested in increasing team cohesion, interest, and motivation to study or work, as well as the creation of closer and trusting relationships, and an atmosphere of psycho-emotional safety.

Recommendation for Researchers: This topic requires more observations to verify the influence of student personality on the effectiveness of virtual team building in intelligent collaborative learning environments.

Impact on Society: The study highlights the importance of communication between the student and the teacher, as well as between students, as psycho-emotional well-being in the micro-society results in a better academic performance.

Future Research: Further research can be aimed at studying the difference in the effectiveness of team building in online and offline learning environments, as well as the impact of team building on the teaching staff.

Background/Aim: Chromophobe renal cell carcinoma (CRCC), eosinophilic variant clear cell RCC, and oncocytomas are renal neoplasms with eosinophilic cytoplasm, and their differential diagnosis is challenging despite significant advances in molecular pathology. Although many biomarkers have been identified for the differential diagnosis of these neoplasms, specific markers have not yet been reported. No studies were found in the literature on the relationship between these tumors and the new molecules DARS2, reelin, and enkurin. This paper aims to determine the roles of these proteins in renal neoplasms with eosinophilic cytoplasm.
Methods: The study retrospectively analyzed 30 EC RCC, 30 CRCC, and 30 oncocytoma cases, evaluated among renal neoplasms with eosinophilic cytoplasm, independent of demographic characteristics, in the Fırat University Medical Pathology Laboratory between 2012 and 2022. The most representative samples of the tumor were selected for each group, and the expression of DARS2, reelin, and enkurin proteins was evaluated by the immunohistochemical method.
Results: The histoscore of DARS2 expression was highest in EC RCC and least in CRCC. DARS2 was seen to differentiate CRCC from oncocytoma and EC RCC. The histoscore of reelin and enkurin protein expression was highest in oncocytoma and lowest in ECRCC. The difference between the groups was statistically significant (P<0.05).
Conclusion: DARS2 can be a useful biomarker for differentiating CRCC from EC RCC and oncocytoma, and enkurin and reelin can differentiate among these three groups.

The specification of gasoline 91, according to Dirjen Migas decree No. 3674 K/24/DJM/2006 dated March,17 2006 define the limit (maximum) of aromatic content 50%volume, and benzene 5.0% volume, but does not define boundary for olefin content as its is regulated in others countries. Olefin compound happened to be saturated hydrocarbon, its has higher octane number, unstable, produces gum that later on could build up as deposit on intake valve of combustion chamber or nozzle tip of fuel injection system. The objective of this study was to know how far the influence of olefin content in gasoline 91 to deposit build-up in intake valve of motor bike engine after cruising on road test for certain distance. For this purpose, the motor bike will be fueled with gasoline 91 with olefin content variations and will be compared to motor bike that cruised at the same route and distance accumulation with regular gasoline 91. Effect of several volume variety of olefin content in gasoline againts deposit development of intake valve engine will be discuss in this paper.
Framing as Lobbying with Limited Resources: A Conceptual Discussion On Contemporary Ethnic Lobbying in The US / Sınırlı Kaynaklarla Bir Lobicilik Yöntemi Olarak Çerçeveleme: ABD’deki Güncel Etnik Lobicilikle İlgili Kavramsal Bir Tartışma
Authors: DEMİR Turgay

Due to the main characteristic of the American society as well as its political system, ethnic lobbying has become an important concept and activity in order to influence the domestic and foreign policy of the United States. By providing a conceptual discussion on the contemporary ethnic lobbying in the US, this article aims at demonstrating the importance of framing strategy for ethnic lobbying groups which have limited resources to promote their interests. The article reviews the existing literature on ethnic lobbying in the US by specifically considering the recent studies regarding the relatively new lobbying groups. Consequently, it argues that framing strategy can become an effective lobbying strategy not only for the lobbies that have access to the United States’ system with an institutional existence in its capital but also for those attempting to gain access to the policymaking communities in this country. Additionally, in order to achieve their specific purposes, ethnic lobbies can apply to the methods of strategic framing and normative framing during their lobbying campaigns.

O teiídeo Ameiva ameiva é comumente encontrado em ambientes abertos naturais ou antropizados ao longo da América do Sul, parte da América Central e na Florida, onde foi introduzido. Invertebrados e principalmente vertebrados são relatados como predadores de A. ameiva. No entanto, a maioria dos registros sobre as interações entre A. ameiva e seus predadores são baseados em casos fortuitos. Nesta nota, documentamos a predação de um espécime de A. ameiva pelo gavião-caboclo Herospizias meridionalis no sudeste do Brasil. Além disso, também quantificamos a diversidade de predadores de A. ameiva por meio da revisão da literatura disponível e de fotografias científicas cidadãs. Encontramos registros de predação de A. ameiva em 71 estudos e sete fotografias científicas cidadãs. Duas espécies de invertebrados e 62 de vertebrados foram relatadas como predadores de A. ameiva. As serpentes (29 espécies) foram os predadores mais comuns de A. ameiva, seguidas pelas aves (16 espécies), mamíferos (13 espécies), lagartos (três espécies) e anuros (uma espécie). Espécies de Accipitriformes identificadas como predadoras de A. ameiva, incluem Buteo lineatus, B. nitidus, B. platypterus, Gampsonyx swainsonii, Geranoaetus albicaudatus e Heterospizias meridionalis. Encontramos somente dois registros de predação de A. ameiva por H. meridionalis, um no Suriname e outro na Costa Rica. Assim, registramos pela primeira vez a predação de H. meridionalis sobre A. ameiva no Brasil.

Published: March 2023

Two studies examined the question of whether photograph taking of an event influences the positivity of the evaluations of the event at a later point in time. Memories of photographed events yielded higher positivity ratings than memories that were not photographed. Although we expected fading of positivity ratings to occur more slowly over a period of two months for memories of photographed events, we found faster affect fading for those memories in Study 2 instead. The findings of the two studies support the idea that taking photographs of events sustains the affective reconstruction of autobiographical memories, regardless of whether these events are special, such as vacation memories, or more mundane, such as memories of the past weekend.
