Objetivou-se avaliar o efeito residual de diferentes recomendações de adubação e momentos de aplicação de adubação nitrogenada após a desfolhação sobre as características morfogênicas, estruturais e produtivas do Megathyrsus maximus cv. Mombaça no período seco do ano. Utilizou-se o delineamento em blocos casualizados em esquema fatorial 4 x 3, com 4 repetições. Os tratamentos foram constituídos pelas recomendações de adubação: Manual 5ª aproximação (5AP), Manual do Pará (MP), Reposição de nutrientes (RP) e modelo adaptado de Michaelis e Menten (MM) em três momentos de aplicação da fonte de nitrogênio (N) após desfolhação (dia 0, 3 e 6). As adubações com N foram realizadas no período das águas e no período de transição. A estratégia 5AP com N no dia 0 apresentou os maiores valores para massa seca de lâmina foliar (MSLF) e número de folhas vivas e os menores para taxa de senescência foliar e massa seca de material morto. Já a recomendação MP com N no dia 6 apresentou ou maiores valores para MSLF. A adubação nitrogenada no final do período das águas, promove aumento do comprimento médio de lâmina foliar e do número de folhas vivas além de promover redução de material morto da forragem no período seco.

RESUMO

A inseminação artificial em cadelas contribui para o melhoramento genético da espécie, previne algumas doenças sexualmente transmissíveis através da cópula e possibilita a reprodução de animais que não poderiam copular de forma natural, seja por motivos anatômicos, geográficos ou comportamentais. Todavia, nem sempre é possível utilizar o sêmen fresco, sendo assim necessário um diluente para resfriar e mantê-lo viável por determinado período. Diante disso, o objetivo com este trabalho foi analisar o sêmen canino diluído em água de coco e refrigerado, à 5 ºC em diferentes tempos. Foram utilizados cinco cães da raça Hounds do Brasil, realizando três colheitas de sêmen de cada animal, com intervalos de sete dias. Os ejaculados foram mantidos a temperatura de 37 ºC e realizado análises macroscópicas (volume, cor, aspecto e odor) e microscópicas (motilidade, vigor, concentração e morfologia espermática). Em seguida, os ejaculados foram diluídos em água de coco natural a uma concentração de 200 milhões de espermatozoides/mL, e mantidos à temperatura de 5 °C, por até 72 horas. Nos intervalos de seis, doze, vinte e quatro, trinta e seis, quarenta e oito, e setenta e duas horas, as amostras foram avaliadas quanto a motilidade e vigor espermático. Os ejaculados frescos apresentaram em média volume de 6,2 mL, cor branca, aspecto aquoso a leitoso, odor “sui generis”, motilidade espermática de 89,5 %, vigor espermático 4,3, concentração média de 418 x106 espermatozoides/mL e 7,3% de alterações patológicas. Após o início do resfriamento à 5 ºC, os valores de motilidade e vigor diminuíram com o passar do tempo, sendo os menores valores encontrados após 48 e 72 horas.   O diluente a água de coco in natura mostrou-se eficiente para refrigeração de sêmen canino, à 5 ºC, conservando-o por um período de até 36h após a colheita, conforme preconizado pelo Colégio Brasileiro de Reprodução Animal.

Authors: Rangel-Ruiz Karelia Liliana , Granados-Olvera Jorge Alberto , Vargas-Solano Zaira
Published: May 2023

Several studies have proposed Project-Based Learning (PBL) as one of the most effective methodologies to achieve competency-based education. The objective of this work was to test the PBL methodology in a group of university to meet competencies. This test was applied to 25 students group divided into teams that were tasked with developing a prototype for a different part of a unit operation. The final product was the demonstration of the operation of the prototypes individually and together. In the first part, students were asked to make a design proposal. Once the design was accepted, the construction of the equipment with commonly used materials was prepared. Subsequently, the performance and characteristics of the assembled prototypes were presented to an evaluation committee. Based on the results obtained, it can be concluded that the PBL methodology proposed in this work contributed to the development of competence by students. We believe that the use of the PBL methodology could enrich the learning of Engineering students, as well as bring it closer to real scenarios.

Published: May 2023

The rise of industry 4.0 (I4.0) technologies increases with the passing of days, as well as their permeability in areas of other kinds, such as education. Currently the term coined for this is Education 4.0 (E4.0) which can be seen as a paradigm and can be conceived as an educational approach that uses the technological axes of I4.0 to optimize the teaching-learning process. One of the technologies that have been implemented the most in E4.0 is augmented reality (AR). However, this technology generally requires a high degree of expertise, which is why this paper proposes a methodology for the creation of applications (app) with AR that can be used as teaching resources in different subjects and educational programs of an affordable and intuitive way. Which is ad hoc to the objective pursued, allowing the creation of apps with AR where the use goes hand in hand and the creativity of the user who will insert it in the pedagogical process corresponds to him and allows students to enter the E4.0.

The purpose of research is to determine the feasibility of laparoscopic pancreatoduodenectomy in tumors of the periampullary zone. Material and methods. In the period from 2016 to 2022 at the Syzganov National Scientific Center of Surgery, 193 patients underwent PD with a diagnosis of a tumor of the periampullary zone. Of these, 6 patients were performed laparoscopically. All patients who underwent LPD were female. The age of the patients ranged from 15 to 77 years (average age – 55,7 years). Results. In 4 (66.7%) patients, cancer of Ampulla of Vater was detected, in 2 (33.3%) pancreatic head cancer. According to the final histology data, adenocarcinoma and the degree of differentiation G2 were detected in all cases. Data on the histology and size of the tumor are summarized in Table 1. The average age of patients was 55.7 years. All patients had a clinic of mechanical jaundice before surgery; the average levels of bilirubin in the blood were 121.3 mmol/l. Accordingly, all patients underwent drainage of the biliary tract. Of these, 5 (83.3%) patients underwent percutaneous stenting and 1 (16.7%) endobiliary stenting. Conclusion. Thus, we presented our initial experience of performing laparoscopic PD. Our results shows the feasibility of laparoscopic PD safely and radically for tumors of the periampullary zone in certain cases. The accumulation of experience in such interventions leads to an improvement in immediate results and a reduction in postoperative complications, the operative time.

Stroke is the second leading cause of death and the third leading cause of disability globally. This literature review described risk factors and diagnostic aspects of ischemic stroke prevention. Carotid stenosis and occlusion is a treatable cause of ischemic stroke, which can be diagnosed by duplex scanning of the brachiocephalic arteries. The reasons for the low effectiveness of preventive measures for ischemic stroke are the incomplete collection of anamnesis for risk factors that affect the clinical prognosis, the low use of modern diagnostic methods by primary health care general practitioners in the screening of patients.

Published: May 2023

A diamond-like carbon (DLC) film was deposited using high-power pulsed magnetron sputtering. The effect of pulse width on the deposition of DLC film was investigated under constant peak power density or average power density to clarify the densification mechanism of DLC film. The maximum hardness of 25 GPa analyzed by nanoindentation was obtained using Ar gas without negative substrate bias voltage at pulse width 30 μs and a peak power density of 1.5 kW cm−2. The flux and energy of C+ and Ar+ incident to the DLC film was evaluated by using energy-resolved and time-resolved mass spectrometry to clarify the relation between the input power to the target and the behavior of produced ions. The change in hardness is well correlated with the ion flux ratio C+/Ar+. This result indicates that a flux and energy of Ar+ as well as C+ is a key parameter to characterize the microstructure of DLC film.

Authors: Saira Luke Moby , Subhash Kiran , Bai JT Ramani , Jitendranath Ashish
Published: May 2023

Background & objectives: The objective of this study was to evaluate the prevalence of Non-typhoidal Salmonella and to nd their antibiotic
susceptibility pattern in a tertiary care hospital in South India. A signicant global health issue is the steadily rising percentage of Non-typhoidal
Salmonella (NTS) infections in people. A descriptive study was conducted at Methods: a tertiary care teaching hospital in South India. Culture and
sensitivity of stool samples of clinically suspected patients were done in the Microbiology laboratory from Sree Gokulam Medical College and
Research Foundation. All samples were inoculated onto appropriate culture plates. Colonies suspected as Salmonella were identied by standard
laboratory methods, initially by manual biochemical tests and by the VITEK-2 automated systems (bioMérieux) and nal serotyping by polyvalent
antisera. 3 of the Salmonella isolates were sent to CMC, Vellore, India for serotyping. Antibiotic susceptibility tests were performed by Kirby
Bauer's disc diffusion method on Mueller-Hinton agar and results were interpreted as per the CLSI guidelines (2022). Signed informed consent was
obtained from all participants. Tests were performed in the clinical Microbiology Laboratory under the Department of Microbiology, Sree
Gokulam Medical College and Research Foundation, Venjaramoodu, Trivandrum. Of the 244 mot Results: ion samples, Non-typhoidal
Salmonella isolated were from 20 motion samples. The predominant serotype isolated was Salmonella Typhimurium (S. Typhimurium) in
16(80%) followed by Salmonella enteritidis in 3(15%) and Salmonella C2 in 1(5%) isolates. It was noticed by an increasing trend of resistance to
Ampicillin, Chloramphenicol, Cephalosporins (Third generation) and Quinolones over this 18 month study. Based on this study, Conclusions:
faecal prevalence of NTS (8.20%) were increasing among motion samples. Majority of isolates were from females (75%) with a mean age group
belonging to Adults (46-60yrs). Except for Ampicillin and Cotrimoxazole, NTS isolates exhibited high rates of resistance to rst-line antibiotics.
The gradual but consistent increase in resistance to Ampicillin, Fluoroquinolones, third generation Cephalosporins may restrict future treatment
1
options. Hence periodic monitoring of NTS infections, serotype distribution and antimicrobial resistance trend is recommended .
COMPARING DIAGNOSTIC ACCURACY OF LUNG ULTRASOUND AGAINST CHEST XRAY FOR DETECTION OF PNEUMOTHORAX USING HRCT AS GOLD STANDARD.
Authors: Pawan Kumar , Neeraj Tripathi , Shreshth Tyagi
Published: May 2023

Thoracic trauma is one of the most common locations of injury with an overall mortality rate of up to 10% making its recognition a priority in chest trauma assessment . Imaging plays a key role in guiding interventions and management in patients with chest trauma. Conventional imaging in the form of chest radiographs, ultrasounds, and computed tomography (CT) are usually performed in the emergency settings with CT scan as the gold standard for this diagnosis. But high radiation dose in CT scan has made chest X-ray a popular initial diagnostic tool in these cases. Apart from various disadvantages of chest X ray, many studies suggest its poor sensitivity and specicity in identifying intrathoracic injuries culminating in lower diagnostic yield. Recently, chest ultrasonography has emerged as a portable, inexpensive, safe, and fast alternative for radiography in detection of traumatic intrathoracic injuries. So, the present study was undertaken to compare the diagnostic accuracy of this newly surfaced chest ultrasonography and the conventional chest radiography in identifying traumatic intrathoracic injuries. Objective: To evaluate and compare the accuracy, sensitivity and specicity of chest ultrasound and chest x ray as a diagnostic tool in detection of pneumothorax, in trauma patients using CT thorax as gold standard. Study design: Descriptive study. Place and duration of study :Department of General Surgery, Lala Lajpat Rai Hospital, GSVM Medical College, Kanpur, UP, India, between December 2020 to October 2022. Methodology : In the present descriptive study, patients with traumatic intrathoracic injuries, who were referred to the emergency department between December 2020 to October 2022, were assessed. The patients underwent bedside chest ultrasound (USG), x ray and computed tomography (CT) scan examinations based on ATLS recommendations. Results : Eighty ve patients with mean age 41.13 ± 17.2 ( range 7-87 ) were taken (68.24 % males ).CT scan showed pneumothorax, in 94.12 %, cases Whereas chest ultrasonography in comparison to radiography detected pneumothorax in 69.41 % respectively. Comparison of sensitivity, specicity, positive predictive value and negative predictive value after taking CT thorax as gold standard gave accuracy of 76.27 % to USG thorax and 50.85 % to chest x ray (p =0.0005 )for detecting pneumothorax , Conclusions : The results of the present study showed that ultrasonography is preferable to radiography in the initial evaluation of patients with traumatic injuries to the thoracic cavity.

Material and Method: This comparative observational study was conducted among the patients coming to Department of General Surgery, Aarupadai Veedu Medical College and Hospital, undergoing elective abdominal surgery who were willing to participate in the study by giving informed and written consent. Patients were grouped based on type of skin closure done, group Aare patients with skin staples in elective abdominal surgery and group B are the patients with conventional suture method of skin closure in elective abdominal surgery. Both the group were assessed for the duration of skin closure, the outcome of wound assessed using ASEPSIS score on 3rd, 5th and 7th post-operative day and wound Cosmesis was assessed using Modied Hollander Cosmesis scale on 7th day, after 2 weeks, 6 weeks and on 3rd month of wound healing. All the statistical analysis were analysed using SPSS v21 operating on windows 10. Results: In our study total 120 patients undergoing elective abdominal surgeries were included with 60 patients in each group. The mean age and gender distribution between both groups was found to be similar with no signicant difference. On comparison of number of staples and number of sutures used, it was signicantly higher in staple group than suture group (p<0.05). On comparison of duration of closure it was signicantly lower in staple group than in suture group ( p<0.05). ASEPSIS score at different point of follow-up showed there is signicantly lower mean score among patients in staple group compared to suture group (p<0.05). On comparing wound score using Modied Hollander Cosmesis scale, the mean score was signicantly higher in staple group than in suture group (p< 0.05). The complications at different point of follow- up was also signicantly lower in staple group than suture group (p<0.05). The degree of patient satisfaction was also signicantly higher in stapler group than in suture group. Conclusion: The present study documented a signicant better outcome in patients who underwent skin closures with staples than with conventional sutures in view of duration of closure, ASESPSIS score, Modied Hollander Cosmesis score, complications and patient satisfaction.

Aim: The objective of the present investigation was to investigate the clinical relationship between hypothyroidism and hyperthyroidism in the elderly population as well as the demographics of thyroid dysfunction in this population.Materials and Method: An extensive clinical examination and thyroid function (T3, T4, and TSH) testing were performed on 100 patients older than 60 who were believed to have thyroid problems as part of a prospective study in our tertiary care center. Other pertinent examinations, such as USG & FNAC neck, were carried out when thyroid swelling or nodules were present in order to obtain an accurate diagnosis. As necessary, further analysis was conducted using PS for expert opinion and 2DECHO. The determination of serum T3, T4, and TSH levels using the chemiluminescence assay method served as the basis for the laboratory evaluation of thyroid functioning. Result: In this investigation, it was discovered that 28% patients had thyroid function tests that were abnormal, and 18% of these patients also showed clinical signs of thyroid problems. 22% of cases had hypothyroidism, and 6% had hyperthyroidism. The prevalence of thyroid disorders rises with advancing age. Conclusion: In the elderly, thyroid dysfunction is more common. Older people should have their thyroid function checked, and long-term follow-up should be advised. Thyroid diseases in older individuals should be treated gradually and carefully, as they always need lifelong monitoring.

Patient developed tachycardia and fall in saturation within 20 minutes, which was managed conservatively and procedure was continued. During intraoperative period patient developed muscle rigidity on left hand along with hypotension and hyperthermia, which confused the surgeon and anesthesiologist whether it is attributed to the drug or some other genetic factors. Patient underwent rst episode of cardiac arrest after 45 minutes induction of general anaesthesia. He was resuscitated but developed second episode of cardiac arrest after a few minutes. Patient was shifted to MICU, all supportive and resuscitation measures were given. Despite all resuscitative measures, patient could not be revived and expired on post op day 2. Later on postmortem report revealed presence of 3,4- methylenedioxymethamphetamine (MDMA) in blood and body uids. There has only been one evidence of atracurium induced malignant hyperthermia reported before, but the probablity of devoloping hyperthermia in this case was probably high. The aim of this study was to investigate whether MDMAor Atracurium is a trigger of malignant hyperthermia in this patient

Introduction: The incidence of difcult endotracheal intubation is high in the ICU because of various factors. Most commonly used method for endotracheal intubation is direct laryngoscopy. Video Laryngoscopes are also helpful aids which provide a better laryngeal view in comparison to Direct Laryngoscope. We should aim at minimizing the time required to achieve a secure airway for ventilation in patients presenting to the Emergency Department/ICU. This was a prospective randomized study in Emer Methods : gency ICU in a tertiary care hospital. A total of 90 patients requiring endotracheal intubation in Emergency ICU were included in the study and were randomly divided into two groups. Group A included patients intubated with the help of C-MAC Videolaryngoscope and Group B included patients intubated with Macintosh Laryngoscope. The primary outcome was to determine overall successful intubation rates. Secondary outcome was to measure rst attempt successful intubation rates, time to intubation, requirement of External Laryngeal Manipulation, requirement of any intubating aids. Patients in Group A and Results : Group B showed an overall similar intubation success rate (p=0.213). Rate of rst attempt intubation in Group A and Group B was similar (p=0.120). Average time to intubation with Group A and Group B was also similar (p=0.0647). Requirement of ELM was lesser with Group A as compared to Group B (p=0.038). The requirement of use of intubating aids was lesser in Group A vs Group B (p=0.003). The use of C- Conclusion : MAC video laryngoscope provided better glottis visualization but resulted in similar rst attempt intubation rates, almost similar time to intubation. C-MAC group required lesser overall requirement of ELM and use of intubating aids when compared to the Macintosh Laryngoscope. Thus, C-MAC® Videolaryngoscopy seems to be a useful technique as the initial approach for endotracheal intubation in the ICU.

Objective: Ropivacaine has the benet of providing appropriate intraoperative anaesthesia and effective postoperative analgesia when used for lower limb procedures under spinal anaesthesia, but some patients still experience pain after the medication has taken its full course of action. Adjuvants added to local anaesthetics have the advantage of extending the sensory-motor block's duration and lowering the overall dose necessary.4 This study compared Clonidine and Fentanyl as adjuvants to intrathecal ropivacaine in enhancing the quality of anaesthesia by postponing the requirement for analgesics. Methods: 100 Patients who were undergoing lower limb surgeries were selected for the study and divided into two groups of 50 each. Patients were randomly allocated to one of the two groups using envelope method for blinding the investigator. GROUP A patients received 2.5ml 0.75% Ropivacaine(18.75mg) + Clonidine(60μg) 0.2ml, GROUP B patients received 2.5ml 0.75% ropivacaine(18.75mg) +Fentanyl (20mcg) 0.2ml. The following parameters were noted: Time of injection of subarachnoid block, Time of onset of sensory block at T10 level, Time of onset of motor block, Duration of motor block, Degree of sedation. Results and discussion: No difference in the onset of sensory and motor blockade between the two groups. There was statistically signicant prolongation in the duration of motor blockade in clonidine group 195.6 minutes when compared with fentanyl group 157.8 minutes (p < 0.001). Analgesic duration was signicantly higher in clonidine group 321.70 ± 48.93 min when compared with fentanyl group 273.60 min (p = < 0.001).The difference in haemodynamic parameters – heart rate, systolic & diastolic blood pressure, mean arterial pressure (except for systolic blood pressure at 150 minutes) were statistically insignicant between both the groups. Sedation was slightly higher in the fentanyl group when compared to clonidine group but was statistically insignicant. None of the patients required supplemental oxygen, analgesia, or anxiolysis intraoperatively. No signicant difference in the incidence of complications like bradycardia, hypotension, respiratory depression etc between the two groups. Conclusion: In our study subarachnoid block with 0.75% isobaric ropivacaine (2.5ml) for lower limb surgeries with addition of clonidine 60mcg as anaesthetic adjuvant has advantage over fentanyl 20 mcg, as it increases the duration of spinal anaesthesia and increases postoperative analgesic duration. No signicant complications were recorded in both study groups
Neural Networks Detect Inter-Turn Short Circuit Faults Using Inverter Switching Statistics for a Closed-Loop Controlled Motor Drive

Published: May 2023

Early detection of an inter-turn short circuit fault (ISCF) can reduce repair costs and downtime of an electrical machine. In an induction machine (IM) driven by an inverter with a model predictive control (MPC) algorithm, the controller outputs are influenced by a fault due to the fault-controller interaction. Based on this observation, this study developed neural network models using inverter switching statistics to detect the ISCF of an IM. The method was non-invasive, and it did not require any additional sensors. In the fault detection task, an area under receiver operating characteristics curve value of 0.9950 (95% Confidence IntervaI: 0.9949 - 0.9951) was obtained. At the rated operating conditions, the neural network model detected and located an ISCF of 2-turns (out of 104 turns per phase) under 0.1 seconds, a speedup of more than two times compared to the thresholding-based method. Moreover, we published the switching vector data collected at various load torque and shaft speed values for healthy and faulty states of the IM, becoming the first publicly available ISCF detection dataset. Together with the dataset, we provided performance baselines for three main neural network architectures, namely, multi-layer perceptron, convolutional neural network, and recurrent neural network.

Published: May 2023

Functional electrical stimulation (FES) is a promising technology for restoring reaching motions to individuals with upper-limb paralysis caused by a spinal cord injury (SCI). However, the limited muscle capabilities of an individual with SCI have made achieving FES-driven reaching difficult. We developed a novel trajectory optimization method that used experimentally measured muscle capability data to find feasible reaching trajectories. In a simulation based on a real-life individual with SCI, we compared our method to attempting to follow naive direct-totarget paths. We tested our trajctory planner with three control structures that are commonly used in applied FES: feedback, feedforward-feedback, and model predictive control. Overall, trajectory optimization improved the ability to reach targets and improved the accuracy for the feedforward-feedback and model predictive controllers (p < 0.001). The trajectory optimization method should be practically implemented to improve the FES-driven reaching performance.

An unsupervised machine learning algorithm utilizing nonlinear dimensionality reduction has been developed to interface with spectroscopic measurements from an atomic rubidium optical magnetometer. The magnetometer uses Electromagnetically Induced Transparency (EIT) optical spectroscopy with atomic vapor cells in order to observe magneto-sensitive spin transitions of the 87Rb atom. The Rb EIT measurements result in the observation of seven transmission peaks associated with the available two-photon resonances between the Rb D1 line Zeeman sublevels. The developed algorithm correlates the waveform of the EIT spectra and the directionality of the local magnetic field using kernel principal component analysis (KPCA). The analysis, implemented with a radial basis function (RBF) kernel trick, was found to neatly cluster the EIT spectra according to the direction of the local magnetic field in the reduced dimensional feature space. The KPCA projections demonstrated a smooth curve in a three-dimensional feature space, and the resulting curve was modeled with a support vector regression (SVR) machine. We found that if the direction of the magnetic field is undefined initially, the measurement accuracy is better than 3 degrees in both azimuthal and longitudinal angles with respect to the real direction of the magnetic field. If the magnetometer is configured so that the azimuthal angle of the field is defined, the KPCA- SVR algorithm is capable of predicting the longitudinal angle of the local magnetic field within 1 degree of accuracy. These results suggest that the dimensionality reduction methods may be a powerful tool for approaching regression problems in optical spectroscopy.

Published: May 2023

Relative time emerges from relative frequencies. It is the phase shift in relative frequencies due to infinitesimal loss in wave energy and corresponding enlargement in the wavelengths of oscillations; which occur in any clock between relative locations due to the relativistic effects or difference in gravitational potential; result error in the reading of clock time; which is wrongly presented as time dilation.
On the Effectiveness of Quasi-Helmholtz Projectors in Preconditioning Problems with Junctions
Authors: Bourhis Johann , Merlini Adrien , Andriulli Francesco P.
Published: May 2023

The electric field integral equation (EFIE) is known to suffer from ill-conditioning and numerical instabilities at low frequencies (low-frequency breakdown). A common approach to solve this problem is to rely on the loop and star decomposition of the unknowns. Unfortunatelly, building the loops is challenging in many applications, especially in the presence of junctions. In this work, we investigate the effectiveness of quasi-Helmholtz projector approaches in problems containing junctions for curing the low-frequency breakdown without detecting the global loops. Our study suggests that the performance of the algorithms required to obtain the projectors in the presence of junctions is maintained while keeping constant the number of sheets per junction. Finally, with a sequence of numerical tests, this work shows the practical impact of the technique and its applicability to real case scenarios.

This paper presents a real-time monocular SLAM system that utilizes a point map and search-by-projection approach for accurate localization and mapping. The system maintains a map of 3D points observed in multiple frames and extracts keypoints and descriptors from each frame. It establishes correspondences between frames and map points using search-by-projection, recording observations based on proximity and feature similarity. Pose optimization is employed to refine camera poses and improve trajectory estimation. Experimental results demonstrate robust localization and mapping in real-time, even in challenging environments with dynamic scenes and significant camera motion. The proposed system offers efficiency for immediate feedback and response in various applications. 
Speech Emotion Recognition in Italian Using Wav2Vec 2.0 and the Novel Crowdsourced Emotional Speech Corpus Emozionalmente
Authors: Catania Fabio
Published: May 2023

Speech emotion recognition (SER) relies on speech corpora to collect emotional voices for analysis. However, emo- tions may vary by culture and language, and resources in Italian are scarce. To address this gap, we launched a crowdsourcing campaign and obtained Emozionalmente, a corpus of 6902 samples produced by 431 non-professional Italian speakers verbalizing 18 sentences expressing the Big Six emotions and neutrality. We conducted a subjective validation of Emozionalmente by asking 829 humans to guess the emotion expressed in the audio clips, achieving an overall accuracy of 66%. Additionally, we fine- tuned the deep learning wav2vec 2.0 model on Emozionalmente and achieved good performance, with an accuracy of around 81- 83%. In this paper, we describe the design choices, a descriptive analysis of the corpus, and the methodology and results of the behavioral and computational studies conducted on the dataset. Our work provides an alternative and extensive resource for linguistic and speech-processing research on the Italian language.
