Alcances y cambios de la deuda de hogares en Bahía Blanca; Scope and changes in household debt in Bahía Blanca Cantamutto, Francisco J. El presente artículo presenta los hallazgos en torno a la dinámica de ingresos y deudas de los hogares de Bahía Blanca, Argentina. El estudio de la situación financiera de los hogares ha cobrado relevancia de los últimos años. Desde la agenda de los organismos internacionales de crédito, la agenda de la inclusión financiera es presentada como un instrumento para la lucha contra la pobreza. Sin embargo, los resultados no parecen tan lineales. El financiamiento en los hogares muestra diferencia según la situación socio-económica de los hogares, mostrando diferentes fuentes, motivos y usos. En este artículo se discute esta situación a partir de información cuantitativa recopilada entre 2020 y 2023, período que atraviesa diferentes fases del ciclo económico nacional. Se encuentran impactos diferenciales, que abren la puerta a suponer que la deuda para los hogares esconde situaciones de vulnerabilidad de derechos básicos.; This article presents the findings regarding the dynamics of income and debt of households in Bahía Blanca, Argentina. The study of the financial situation of households has gained relevance in recent years. From the agenda of international credit organizations, the financial inclusion agenda is presented as an instrument for the fight against poverty. However, the results do not seem so linear. Financing in households shows differences depending on the socioeconomic situation of the households, showing different sources, reasons and uses. This article discusses this situation based on quantitative information collected between 2020 and 2023, a period that goes through different phases of the national economic cycle. Differential impacts are found, which open the door to assuming that household debt hides situations of vulnerability of basic rights.

Primer registro de Leopardus braccatus (Carnivora: Felidae) en el bosque seco chiquitano, Bolivia Nogales Ascarrunz, Paola; Aramayo Ledezma, Gabriel; Aliaga Rossel, Enzo; Aramayo Bejarano, José Luis; Lucherini, Mauro; Jansen, Martin El complejo del Leopardus colocolo, según una reciente actualización taxonómica, ha sido dividido en cinco especies. Una de estas es Leopardus braccatus conocida como gato del pantanal, distribuido en Bolivia, Brasil y Paraguay. A pesar de su distribución, esta es una especie poco estudiada. Presentamos aquí un nuevo registro de esta especie, siendo el primero registrado en el bosque seco chiquitano, un ecosistema amenazado que previamente no se consideraba su hábitat. Este hallazgo se llevó a cabo como parte de un programa de monitoreo de felinos con cámaras trampa, donde adicionalmente seis especies de félidos fueron detectadas en un área de 41km2, lo que indica una alta diversidad de felinos en esta ecorregión. Además, se identificaron amenazas directas para el gato del pantanal, como la actividad agrícola y ganadera, los perros domésticos y la cacería ilegal. La relevancia de este nuevo registro radica en su ubicación en el límite occidental-sur de la distribución conocida para Bolivia, así también como sus características morfológicas similares a la especie L. munoai. Esto subraya la necesidad de realizar investigaciones adicionales para comprender mejor su distribución y conservación. Estudios futuros podrían explorar también las similitudes morfológicas y de distribución entre L. braccatus y L. munoai.; The Leopardus colocolo complex, according to a recent taxonomic update, has been divided into five species. One of these is Leopardus braccatus, known as the Pantanal cat, distributed in Bolivia, Brazil, and Paraguay. Despite its distribution, this species remains understudied. Here, we present a new record of this species, the first documented in the dry Chiquitano forest, a threatened ecosystem previously not considered its habitat. This finding was part of a wild felid camera trap monitoring program using camera traps, where additionally six species of felids were detected in a 41km2 area, indicating high felid diversity in this ecoregion. Furthermore, direct threats to the Pantanal cat were identified, such as agricultural activity, presence of livestock, domestic dogs, and illegal hunting. The significance of this new record lies in its location at the southwestern limit of the known distribution for Bolivia, as well as its morphological similarities to the species L. munoai. This underscores the need for further research to better understand its distribution and conservation. Future studies could also explore morphological and distributional similarities between L. braccatus and L. munoai.

Ovarian leukocytes: Association with follicular persistence and cyst formation in dairy cows Stassi, Antonela Florencia; Etchevers, Lucas; Cainelli, Sofía; Renna, Maria Sol; Baravalle, María Eugenia; Acosta, Verónica; Salvetti, Natalia Raquel; Ortega, Hugo Hector One of the initial causes of cystic ovarian disease (COD) is a failure in the normal ovulation mechanism. This study aimed to characterize the populations of immune cells (T-lymphocytes, B-lymphocytes, monocytesmacrophages and granulocytes) present in the ovary of cows with COD and induced follicular persistence, and evaluate their relation with follicular persistence and cyst formation. The follicular persistence model was developed using a progesterone (P4) slow-release intravaginal device, to obtain subluteal concentrations of P4.Results evidenced that T-lymphocytes, B-lymphocytes and monocytes-macrophages in the cortex, medulla, and theca externa and interna of dominant follicles were higher in the control group than in the COD and all persistence groups. Granulocytes in the medulla and theca externa of dominant follicles were lower in the control group than in the COD group, and those in the cortex and medulla were lower in the control group than in the persistence groups. The presence of T-lymphocytes, B-lymphocytes and granulocytes in the follicular fluid was abundant, especially that of granulocytes, without differences between control and COD cows. These results suggest that the immune system potentially plays a role in the local mechanisms of COD pathogenesis in dairy cows. In spontaneous COD and in our follicular persistence model, the distribution of the cells studied was different from that in the control group. However, to our knowledge, this is the first report describing the presence of immune cells in bovine follicular fluid samples and the expression of steroid hormone receptors in infiltrating immune cells in the bovine ovary.

Estimación teórica y computacional del stopping power para electrones y protones de un dosímetro pagat infundido con nanopartículas de oro en rango energético de aplicaciones terapéuticas; Theoretical and computational estimation of the stopping power for electrons and protons for a pagat dosimeter infused with gold nanoparticles in the energy range of therapeutic applications Salinas Domján, Carolina; Mattea, Facundo; Scarinci, Ignacio Emanuel; Valente, Mauro Andres; Romero, Marcelo Ricardo El presente trabajo estudia el comportamiento del poder de frenado o stopping power de un sistema de dosimetría por gel polimérico de tipo PAGAT, infundido con nanopartículas de alto número atómico formadas por átomos de oro, con una concentración de 1% en masa. El estudio se realiza para diferentes energías de haces de electrones y protones dentro de rangos de aplicaciones terapéuticas, inicialmente con una estimación teórica y posteriormente mediante el empleo de técnicas de simulación con código Monte Carlo: PENELOPE en el caso de electrones, y FLUKA en el caso de protones. Los resultados obtenidos de manera analítica muestran un comportamiento promisorio para sistemas tejidoequivalente infundidos con nanopartículas de oro, mientras que los resultados obtenidos por simulación poseen una mejor correspondencia con modelos que consideran el camino neto recorrido, a comparación de modelos que utilizan el espesor de la muestra como aproximación a configuraciones experimentales.; The present work focuses on the behavior of the stopping power of a polymer gel dosimetry system, known as PAGAT, infused with high atomic number nanoparticles formed by gold, with a 1 % mass concentration. The study is carried out for different energies of electron and proton beams within ranges of therapeutic applications, first by theoretical assessment, and then by simulation with Monte Carlo codes: PENELOPE in the case of electrons, and FLUKA in the case of protons. The results obtained analytically show promising behavior for gold nanoparticle infused tissueequivalent systems, while the simulation results show better correspondence with models that consider the net path traveled, instead of models based on the thickness of the samples as typically done in experimental determinations.

Vejeces, tecnologías digitales y pandemia: sobre las (im)posibilidades de conexión en el aislamiento social; Old age, digital technologies and the pandemic: on the (im)possibilities of connectedness amidst social isolation Guzzo, María del Rosario Durante la pandemia del COVID-19, la pregunta por los modos en que las personas mayores se vinculaban con y a través de las tecnologías digitales (TD) adquirió una urgencia inusitada. Buscando contribuir a su comprensión, el artículo analiza los procesos de apropiación de TD de mujeres mayores residentes en La Plata y Ensenada entre 2020 y 2022. Para ello, se examinan trece entrevistas biográficas realizadas con estudiantes del Programa de Educación Permanente para Adultos Mayores (PEPAM), de la FaHCE (UNLP). En particular, se profundiza en el análisis de dos prácticas mediadas por el celular e Internet: los intercambios de mensajes y videollamadas (principalmente a través de WhatsApp), así como el uso de plataformas de videoconferencia para clases virtuales.Los hallazgos indican que estos procesos de apropiación deben ser interpretados a la luz de las desigualdades estructurales preexistentes sobre las condiciones de acceso y uso de TD, así como de la construcción etaria de la “vejez como riesgo” consolidada durante la pandemia. Asimismo, a partir del reconocimiento de construcciones de sentido complejas y ambivalentes sobre la TD, se advierte que para las entrevistadas los vínculos digitalmente mediados fueron relevantes para mitigar el impacto del aislamiento social pero no suficientes.; During the COVID-19 pandemic, research on the ways in which older people linked with and through digital technologies (DT) acquired an unusual urgency. Aiming to contribute to its understanding, this article analyses the TD appropriation processes of older women living in La Plata and Ensenada between 2020 and 2022. For this purpose, thirteen biographical interviews conducted with students of the Continuing Education Programme for Older Adults (PEPAM) of the FaHCE (UNLP) are examined. In particular, we delve into the analysis of two practices mediated by mobile phones and the Internet: the exchange of messages and video calls (mainly through WhatsApp) and the use of videoconferencing platforms for virtual classes. The findings indicate that these appropriation processes should be interpreted in the light of pre-existing structural inequalities in the conditions of access and use of TD, as well as the age construction of "old age as risk" consolidated during the pandemic. Likewise, based on the recognition of complex and ambivalent constructions of meaning about TD, it can be seen that in the interviewees’ perspective, digitally mediated bonds were relevant to mitigate the impact of social isolation, but not sufficient.

A rhodium-catalyzed C–H activation/cyclization approach toward the total syntheses of cassiarin C and 8- O -methylcassiarin A from a common intermediate Vargas Vargas, Didier Farley; Fonzo, Santiago; Simonetti, Sebastián Osvaldo; Kaufman, Teodoro Saul; Larghi, Enrique Leandro Three short and efficient total syntheses of cassiarin C are reported, from a chromanone common key intermediate. A C–H activation strategy, under rhodium catalysis on its pivaloyl oxime, enabled the installation of the pyridine ring. Dehydrogenation of 8-O-methylcassiarin C afforded 8-O-methylcassiarin A. A kinetic experiment and DFT calculations of the intermediates helped to gain insight into the unusual siteand stereo-specific H/D exchange of cassiarin C in CD3OD.

Current understanding, knowledge gaps, and challenges of mountain permafrost research in the Chilean and Argentinean Andes Fernández Navarro, Hans; Tapia Baldis, Carla Cintia; Rojas, Claudia; Derrien, Morgane; Villaseñor, Tania Mountain permafrost extends over a vast area throughout the Chilean and Argentinean Andes, making it a key component of these mountain ecosystems. To develop an overview of the current state of knowledge on southern Andean permafrost it is essential to outline appropriate research strategies in a warmer climate context . Based on a comprehensive review of existing literature, this work identifies eight main research themes on mountain permafrost in the Chilean and Argentinean Andes: paleoenvironmental reconstructions, rock glacier inventories, permafrost distribution models, internal structure analysis, hydrogeochemistry, permafrost dynamics, geological hazards, and transitional landscape studies. This extensive review work also highlights key debates concerning the potential of permafrost as a water resource and the factors influencing its distribution. Furthermore, we identified several challenges the scientific community must address to gain a deeper understanding of mountain permafrost dynamics. Among these challenges, we suggest tackling the need to broaden spatial focus, along with the use of emerging technologies and methodologies. Additionally, we emphasize the importance of developing interdisciplinary approaches to effectively identify the impacts of climate change on mountain permafrost. Such efforts are essential for adequately preparing scientists, institutional entities, and society to address future scenarios.

Burial Histories, Bodies, and Pots: Mortuary Practices in the Southeastern Rainforests of the Andes during the 1st Millennium a.d. (El Cadillal, Argentina) Vazquez Fiorani, Agustina; Kuijt, Ian; Salazar, Julián Through the control of social memory and the dead, household members in Argentinian Andeanearly Formative villages often used primary and secondary mortuary practices to negotiate powerand identity among the living. In this paper, we explore the material evidence obtained in thelarge-scale salvage excavations of El Cadillal, Argentina, where 51 burials were recovered fromthree burial sites. Between A.D. 0 and 900, people living in the southeastern rainforests placeddeceased household members in ceramic urns and, less frequently, inside of rock enclosures andpits surrounded by a range of grave offerings. Drawing upon this case study, we attempt todisentangle the complex web of relationships between the dead, the living, and the El Cadillalcommunity in order to assess how social memories were crafted through primary and secondarymortuary events and how the repetition of mortuary rituals created a social landscape andmemories of the dead.

Caracterización hidroambiental de cuencas en la Reserva Parque Costero del Sur, Argentina; Hydro-environmental characterization of watersheds within the Parque Costero Sur Reserve, Argentina Glustein, Jazmín Ilana; Arturi, Tatiana Sonia; Berardozzi, Eliana; Delgado, María Isabel A pesar de existir una relativa homogeneidad en diferentes característicasde la región pampeana, el tipo de suelo podría determinar los usosposibles en cada zona, con impactos variables en la hidrología, la químicadel agua, la morfología de los cursos y la biodiversidad. En las reservasde biosfera resulta fundamental generar conocimiento que ayude acomprender la relación entre las actividades productivas desarrolladas yel estado de los ecosistemas. El objetivo de este trabajo es caracterizarlas cuencas hidrográficas dentro de la reserva Parque Costero del Sur afin de aportar al desarrollo de una interpretación conceptual delfuncionamiento hidrológico en este territorio. Se estudiaron tres arroyos-Buñirigo, Juan Blanco y Villoldo- con diferentes grados de intervenciónantrópica. Para ello se caracterizaron morfométricamente sus cuencas, segeneraron mapas de uso del suelo y se realizaron balances hídricos. Sellevaron a cabo dos campañas de muestreo de agua superficial y análisisde parámetros fisicoquímicos y microbiológicos. La diferencia en laconcentración de estos parámetros entre campañas resultó significativa.En todos los casos, los valores de Conductividad Eléctrica (CE), turbidezy Demanda Química de Oxígeno (DQO) fueron mayores durante el períodode déficit y los de Fósforo Reactivo Soluble (PRS) durante el período deexceso hídrico. En cambio, la asociación con la distribución espacial de los sitios de muestreo no reveló tendencias claras. Esta investigación podríaresultar útil para la toma de decisiones relacionadas con la gestión delrecurso hídrico, ya que ciertos parámetros exceden los límitesestablecidos localmente.; Despite the relative homogeneity in different characteristics of the Pampas region, the soil type might determine the possible land uses in each area, with variable impacts on hydrology, water chemistry, watercourse morphology, and biodiversity. In biosphere reserves, it is crucial to generate knowledge that helps to understand the relationship between productive activities and the state of the supporting ecosystems. The objective of this study is to characterize the watersheds within the Parque Costero del Sur reserve to contribute to the development of a conceptual interpretation of the hydrological functioning in this territory. Three streams -Buñirigo, Juan Blanco, and Villoldo- with different degrees of anthropic intervention were studied. To achieve this, their watersheds were morphometrically characterized, land-use maps were generated, and water balances were conducted. Two surface water sampling campaigns were carried out, analyzing physicochemical and microbiological parameters. The difference between campaigns for the concentration of these parameters was significant. In every case, the values of Electrical Conductivity (EC), turbidity, and Chemical Oxygen Demand (COD) were higher during the deficit water period and Soluble Reactive Phosphorus (SRP) values during the excess water period. Instead, no clear trends were found regarding the association with the spatial distribution of the sampling sites along the watersheds. This research might be useful for decision-making related to water resource management, as certain parameters exceed locally established thresholds.

Selective lithium extraction employing lithium manganese oxide-loaded polymeric membranes at natural brine pH and room temperature Arrua, Eva Carolina; Bedogni, Giselle Rocio; Salomon, Claudio Javier; Flexer, Victoria The current technology for lithium extraction from brines is recognized both for its techno-economic disadvantages and its environmental impacts. We have synthesized, characterized, and evaluated particles based on lithium manganese oxide towards selective lithium recovery from complex media. A solid-state synthesis and a hydrothermal method produced sub-micrometre sized particles that showed diameters of 253 nm and 154 nm, respectively, both with very low polydispersity. 23.7 mgLi/gHMO and 30.7 mgLi/gHMO adsorption capacity values were obtained with solid-state synthetic and hydrothermal oxides. The hydrothermally synthesized submicrometre sized particles were incorporated into polymeric membranes aiming at the development of a straightforward technological application. Membranes were prepared from polyacrylonitrile and polyethyleneglycol, and the affinity to lithium was once again evaluated. Membranes showed a high adsorption capacity for lithium (32.7 mgLi/gHMO) with almost identical kinetics and cyclability as the free particles in solution. An excellent selectivity for lithium was confirmed in experiments with a natural lithium-rich brine from the Lithium Triangle. All adsorption experiments were performed at neutral pH and room temperature. An undeniable advantage of membranes vs. sub-micrometre sized particles is that the former do not require centrifugation after successful adsorption/desorption. These three characteristics are fundamental in the perspective of technology scale-up to minimize operational costs.

La vida afectiva en el arte independiente: Territorio sensible en la danza contemporánea del interior provinciano; Affective life in independent art: Sensitive territory in contemporary dance of the provincial interior Bertea, Francisco Miguel Fernando En este trabajo indagamos la vida afectiva en el arte independiente, específicamente en el mundo de la danza contemporánea del Valle de Paravachasca (Córdoba, Argentina), a partir de un trabajo etnográfico colaborativo de participación observante en el grupo Cantorodado, entre los años 2018-2022. Situados en los estudios sociales del arte y el giro afectivo, describimos de forma densa el territorio sensible de este mundo del arte, distinguiendo algunos de los vectores que lo componen, en calidad de tipos reales: una forma de (ganarse la) vida colectiva, una ética del cuidado y una atmósfera afectiva de entusiasmo. Empleamos para ello una propuesta analítica que se mueve en la tensión entre analítica-individuo y analítica-fuerza, entre las libertades relativas de los agentes y las estructuras estructurantes de sujeción. Realizamos así aportes a la comprensión de la vida afectiva de la danza contemporánea independiente y al arte independiente como forma de (ganarse la) vida, desde temáticas específicas, como la moral, la amistad, el management, el wellness y el don, reconociendo que la propuesta analítica empleada puede significar un aporte al estudio de la vida afectiva.; In this paper we investigate the affective life in independent art, specifically in the contemporary dance world of the Paravachasca Valley (Córdoba, Argentina), from a collaborative ethnographic work of observant participation in the Cantorodado group, between the years 2018-2022. Situated in the Social Studies of Art and the affective turn, we make a thick description of the sensitive territory of this art world, distinguishing some of the vectors that compose it, as real types: a way of (earning the) collective life, an ethic of care and an affective atmosphere of enthusiasm. We use an analytical proposal that moves in the tension between analytic-individual and analytic-force, between the relative freedoms of the agents and the structuring structures of subjection. We contribute at the understanding of the affective life of independent contemporary dance and independent art as a way of (earning a) living, from specific aspects linked: morality, friendship, management, wellness and gift. Acknowledging that the analytical proposal used can mean a contribution to the study of the affective life.

Use of cannabidiol-dominant extract as co-adjuvant therapy for type 2 diabetes mellitus treatment in feline: case report Massabo, José Ignacio; Puiatti, Gabriela; Ferrero, Paola Viviana Introduction: Diabetes mellitus (DM) is a common endocrinopathy in felines. Treatment is based on glycemic control and management of clinical signs by insulin administration coupled with a low-carbohydrate and high-protein content diet. However, achieving adequate remission or glycemia control is not always possible. Effects of cannabinoids on the regulation of glucose uptake and the incidence of diabetes have been observed in experimental models. Nevertheless, little is known about their possible relevance in controlling this condition in veterinary and human medicine. Case presentation: This is a case study of an 18-year-old, neutered, mixed-breed female domestic longhair cat diagnosed with type 2 diabetes mellitus. She was treated with long-acting glargine (3 to 5 IU/12 hs), and her diet changed to ultra-processed commercial food for diabetic cats. Three months after the start of the treatment with insulin, Cannabidiol (CBD)-enriched extract in handmade olive oil, THC: CBD ratio = 1:24, was incorporated. The route of administration was oromucosal. After three months, the glycemia was reduced. The patient decreased the polyuria/polydipsia, recovered sleep cycles, remained attentive to all movements, and increased her physical activity. Conclusion: This report provides evidence that using a CBD-rich extract was effective as a co-adjuvant in alleviating clinical signs of DM and concurrent disorders, allowing for the reduction of insulin intake.

Revisiting the massive star-forming complex RCW 122: New millimeter and submillimeter study Duronea, Nicolas Urbano; Bronfman, L.; Ortega, Martin Eduardo; Suad, Laura Andrea; Baume, Gustavo Luis; Mendoza, E.; Carvajal, M.; Cichowolski, Silvina; Arnal, Edmundo Marcelo; Finger, R.; Merello, M.; Gamen, Roberto Claudio In this paper, we present a new multifrequency study of the giant star-forming complex RCW 122. We used molecular data obtained with the ASTE 10 m and the APEX 12 m telescopes, along with infrared observations spanning from 3.6 µm to 870 µm, obtained from available databases. We also incorporated a range of public datasets, including the radio continuum at 3 GHz, narrowband Ha images, and deep JHK photometry. Our analysis focuses mostly on cataloged ATLASGAL sources, showcasing a spectrum of evolutionary stages from infrared dark cloud (IRDC)/high-mass protostellar object (HMPO) to ultra-compact HII region (UCHII), as inferred from preliminary inspections of the public dataset. Based on ASTE HCO+(4‑3) and CO(3‑2) data, we identified five molecular clumps, designated A, B, C, D, and E, as molecular counterparts of the ATLASGAL sources. These clumps have radial velocities ranging from ~‑15 km s‑1 to ‑10 km s‑1, confirming their association with RCW 122. In addition, we report the detection of 20 transitions from 11 distinct molecules in the APEX spectra in the frequency ranges from 258.38 GHz to 262.38 GHz, 228.538 GHz to 232.538 GHz, and 218.3 GHz to 222.3 GHz, unveiling a diverse chemical complexity among the clumps. Utilizing CO(2‑1) and C18O(2‑1) data taken from the observations with the APEX telescope, we estimated the total LTE molecular mass, ranging from 200 M⊙ (clump A) to 4400 M⊙ (clump B). Our mid- to far-infrared (MIR-FIR) flux density analysis yielded minimum dust temperatures of 23.7 K (clump A) to maximum temperatures of 33.9 K (clump B), indicating varying degrees of internal heating among the clumps. The bolometric luminosities span 1.7×103 L⊙ (clump A) to 2.4×105 L⊙ (clump B), while the total (dust+gas) mass ranges from 350 M⊙ (clump A) to 3800 M⊙ (clump B). Our analysis of the molecular line richness, L/M ratios, and CH3CCH and dust temperatures reveals an evolutionary sequence of A/E→C→D/B, consistent with preliminary inferences of the ATLASGAL sources. In this context, clumps A and E exhibit early stages of collapse, with clump A likely in an early HMPO phase, which is supported by identifying a candidate molecular outflow. Clump E appears to be in an intermediate stage between IRDC and HMPO. Clumps D and B show evidence of being in the UCHII phase, with clump B likely more advanced. Clump C likely represents an intermediate stage between HMPO and HMC. Our findings suggest clump B is undergoing ionization and heating by multiple stellar and protostellar members of the stellar cluster DBS 119. Meanwhile, other cluster members may be responsible for ionizing other regions of RCW 122 that have evolved into fully developed HII regions, beyond the molecular dissociation stage.

Flexible and configurable embedded electrical energy measurement system to acquire and process high-frequency features Véliz, Maximiliano Ezequiel; Real, Gustavo Ernesto; Otero, Alejandro Daniel A novel High-Frequency Electric Energy Metering System to inspect non-conventional features that may be relevant for studying real-time energy disaggregation and control of household appliances is presented. Integration of a data acquisition and control board, designed and built to be assembled with an Arduino Due, with the M90E36A Demo Board, allows for flexible and configurable electrical energy measurements. A key feature is that up to 4 current channels can be measured synchronously. On the one hand, samples can be obtained and processed by the M90E36A IC internal Digital Signal Processor at 3 Hz in the time domain and 2 Hz in the frequency domain. On the other hand, the M90E36A IC direct access memory mode can be operated, allowing 8 kHz pure voltage and current signals to be obtained. Finally, integration with Raspberry Pi allows to design and incorporate a custom signal processor into the study. Additionally, in this article, an application example is presented where the variation of the residual harmonic components of a household appliance is obtained.

Characterising cricket flour from Gryllus assimilis : an alternative source of nutrients for sustainability Toribio, Ezequiel; Correa, María Jimena; Medici, Sandra Karina; Ferrero, Cristina; Arp, Carlos Gabriel A trend to study entomological options as food is turning the practice of entomophagy into a novelresearch field in search for sustainable and accessible sources of nutrients. In this work, cricket (Gryllus assimilis) was processed into flour (CF), and then extracted using different solvents to obtain oils and defatted flours. The repeatability of CF obtention, its nutritional profile, and some of its physicochemical properties were studied. Results showed repeatability with a 28% mass yield for CF production. The CF presented adequate amino acid, mineral, and fatty acid profiles, a high content of dietary fibre, and low available carbohydrates, thus being considered a suitable alternative for inclusion in healthy human diets. Using data obtained from the total nitrogen content, the amino acid profile, and the total dietary fibre determinations, the CF protein digestibility was estimated at 67.4%. Based on experimental data, a mean nitrogen-to-protein conversion factor of 5.76 was calculated for a G. assimilis meal. The study showed that nutritional cricket flour and derivatives can be obtained using non-sophisticated methods.
