Modelo prolab: Kusi-Cushuro, un emprendimiento sostenible para la comercialización de cushuro en el sector turismo

En la actualidad, la necesidad de recuperación del sector de alimentos y bebidas posterior a la pandemia obliga a que la innovación sea un eje central en las propuestas de valor de restaurantes y hoteles. En tal sentido, se identificó un problema complejo, que es la búsqueda continua de la renovación de las propuestas gastronómicas en base a las tendencias actuales de consumo saludable y de productos nativos. Para abordar este problema se aplicó design thinking, donde a través de la empatía se pudo identificar claramente las necesidades del cliente, para posteriormente plantear distintos prototipos que fueron testeados para generar un aprendizaje validado a fin de definir un producto mínimo viable. De esta manera, la solución que se propone es Kusi-Cushuro, un producto basado en el procesamiento del Nostoc sphaericum, conocido con el nombre de “Cushuro”, “Murmunta” y “Llullucha”, etc, que es una cianobacteria de agua dulce con alto valor nutricional, para su venta a hoteles de 4 y 5 estrellas de la zona centro y sur del Perú. Kusi Cushuro desarrollará sus actividades con un enfoque de sostenibilidad ambiental y social, en donde se velará por una extracción inteligente y sostenible del recurso, buscando minimizar el impacto al medio ambiente en la operación del negocio, además de tener un impacto positivo en la calidad de vida de las comunidades que extraen la cianobacteria, con miras a la optimización de su productividad. En relación a la viabilidad financiera de Kusi-Cushuro, el proyecto tiene un VAN de USD783,114 lo cual representa una iniciativa de alto valor para los inversionistas. En cuanto al impacto social del negocio, Kusi-Cushuro tiene una influencia directa en el ODS 8, teniendo un IRS de 33.3%, generando un VAN Social de USD835,300. A partir de los antecedentes expuestos, se recomienda su implementación, así como la continua evaluación de la escalabilidad del negocio a otros lugares de Perú y del mundo.Currently, the need for recovery of the food and beverage sector after the pandemic forces innovation to be a central axis in the value propositions of restaurants and hotels. In this sense, a complex problem was identified, which is the continuous search for the renewal of gastronomic proposals based on current trends in healthy consumption and native products. Design Thinking was applied to address this problem, where through empathy it was possible to clearly identify the client's needs, to later propose different prototypes that were tested to generate validated learning in order to define a minimum viable product. The proposed solution is Kusi-Cushuro, a product based on the processing of Cushuro (algae with high nutritional value) for sale to 4 and 5-star hotels in the central and southern areas of Peru.

Los alcaldes, límites y forma de ejercicio del derecho de propiedad sobre las cosas, encuentra si regulación en esta materia, tanto cuando se asigna "plena" propiedad sobre las mismas, como cuando se atribuye derechos más acotados. Asimismo, se ocupa de varios de los derechos de garantía más importantes que, al permitir actuar directamente sobre la cosa de diversos modos según el derecho de que se trate, posibilitan una más segura satisfacción del interés del acreedor. La creación legislativa de los derechos reales fue reservada desde tiempo muy antiguo, quizás por su importancia en la economía, en la política y en lo social. La voluntad de las partes es una fuerte muy importante para pensar que existe la posibilidad de crear los derechos reales que uno quisiese. En nuestro sistema, esto no se permite, quizás por mantener una seguridad o economía. Es por eso que está prohibida la constitución por acto jurídico de un derecho real que no sean lo que están contemplados en la ley. La reserva legislativa de la creación de derecho reales se conoce con el nombre de Numerus Clausus, pero también existe una posición de la doctrina que considera que es factible considerar a los derechos reales como Numerus Apertus, estamos de acuerdo que los derechos reales se pueden crear por ley, pero también se podría crear por la voluntad de las partes, mientras se cumplan con los requisitos legales adecuados para un derecho real en general y se trate verdaderamente de la creación de un poder directo e inmediato sobre las cosa; de esta manera se podría crear otros derechos reales originarios totalmente o derivados de otros derechos reales ya existentes, mezclándolos entre ellos son tal de alcanzar la figura jurídica más eficiente para nuestro objetivo

Study of the Hydrogen Evolution Reaction Using Ionic Liquid/Cobalt Porphyrin Systems as Electro and Photoelectrocatalysts

In this work, the design and manufacture of graphite paste (Gr) electrodes is carried out, including N-octylpyridinium hexafluorophosphate (OPyPF6) ionic liquid (IL) as binder and modification with Co-octaethylporphyrin (Co), in order to study the hydrogen evolution reaction (HER) in the absence and presence of light. The system is characterized by XRD and FESEM-EDX (Field Emission Scanning Electron Microscopy with Energy Dispersive X-Ray Spectroscopy), confirming the presence of all the components of the system in the electrode surface. The studies carried out in this investigation confirm that a photoelectrocatalytic system towards HER is obtained. The system is stable, efficient and easy to prepare. Through cyclic voltammetry and electrochemical impedance spectroscopy, was determined that these electrodes improve their electrochemical and electrical properties upon the addition of OPyPF6. These effects improve even more when the systems are modified with Co porphyrin. It is also observed that when the systems are irradiated at 395 nm, the redox process is favored in energy terms, as well as in its electrical properties. Through gas chromatography, it was determined that the graphite paste electrode in the presence of ionic liquid and porphyrin (Gr/IL/Co) presents a high turnover number (TON) value (6342 and 6827 in presence of light) in comparison to similar systems reported

Electrochemical conversion of carbon dioxide into CHO- containing compounds on multimetallic porphyrins

This work describes the electrochemical reduction of carbon dioxide in aqueous solution mediated by tetraruthenated metal-loporphyrins (TRP; Co(II) and Zn(II)) in Nafion (Nf) and polyvinyl chloride (PVC) as a support. The comparative aspects of the two polymeric matrices are expressed in terms of the electrocatalytic behavior toward carbon dioxide reduction of both sets of modified electrodes; values of overpotential and turnover frequency were calculated in each case. The modified electrodes under survey were able to reduce carbon dioxide at -600 mV vs Ag/AgCl showing an enhanced reduction current and a decrease in the required overpotential compared to a bare glassy carbon (GC) electrode. Potential-controlled electrolysis experiments were carried out at -1000 mV in order to compare the distribution of products. The production of formic acid, formaldehyde and methanol was confirmed at potentials where reduction of solvent may occur. Measurements of electrochemical impedance spectroscopy show the presence of one active site for GC/Nf/MTRP (where M = Zn(II) and Co(II)) and three for GC/PVC/MTRP. This information corroborates the high values of TOF obtained for GC/PVC/ZnTRP as the best electrocatalyst.Nucleo Milenio - Fondo de Innovacion para la Competitividad, del Ministerio de Economia, Fomento y Turismo, Chile CILIS-RC-130006 FONDECYT 3150170 114119

Encefalitis autoinmune por anticuerpos NMDA a propósito de un caso clínico

Autoimmune encephalitis derives from the inflammation or dysfunction of some parts of the brain caused by antibodies against specific brain antigens, and which generally have a clinical presentation with psychiatric symptoms that often com-plicate the timely diagnosis to be able to start immunosuppressive therapies. Anti-NMDAR antibody encephalitis is more common in children and young adults, and is characterized by the subacute presence of psychiatric disorders, altered consciousness, and epileptic seizures, among others (Erazo, 2019). This report describes a case of anti-NMDA receptor autoimmune encephalitis in a 31-year-old male adult, with a condition characterized by a disorder of the level of conscious-ness, confusing the first diagnostic impressions where it was initially attended. After 15 days of presentation of the clinical picture, he is finally treated at the Hospital ClinicaAlcivar in Guayaquil, where he is admitted to the ICU requiring mechani-cal ventilation and plasmapheresis as part of the treatment that involved several anticonvulsants, and that after almost two months of intensive care , suffers a multiple generalized tonic clonic crisis refractory to treatment, for which he is induced to a barbiturate coma, and Rituximab is included as a new immunosuppressive treatment.Las encefalitis autoinmune derivan de la inflamación o disfunción de algunas partes del cerebro causada por anticuerpos contra antígenos cerebrales específicos, y que generalmente tienen una presentación clínica con sintomatología psiquiá-trica que muchas veces complica el diagnóstico oportuno para poder dar inicio a terapias inmunosupresoras.La encefalitis por anticuerpos anti NMDARes másfrecuente en casos de niños y adultos jóvenes, y se caracterizar por la presencia suba-gudade trastornospsiquiátricos, alteración de la conciencia, crisis epiléptica, entre otros (Erazo, 2019).

On the mechanism of CO2 electro-cycloaddition to propylene oxides

We herein present a systematic study on the mechanism of CO2 electro-cycloaddition to propylene oxide, using both experimental and theoretical procedures. The study considers the analysis of mild and sustainable conditions to obtain cyclic carbonates from CO2 recycling. Within the electrochemical approach, the application of an overpotential in the reaction enhances the reaction yield significantly with respect to the thermal pathway. The quantum-mechanical approach provides relevant information about the reaction mechanism. Specifically, the use of the Lewis acid catalyst Mg2+ in the presence of the [C(4)C(1)Im][Br] ionic liquid provides the best condition for the electro-synthesis. The theoretical predictions were confirmed by a new set of experiments. (C) 2016 Elsevier Ltd.

Nitrite reduction on a multimetallic porphyrin/polyoxotungstate layer-by-layer modified electrodes

Artículo de publicaciónElectro and photoelectrochemical reduction of nitrite in aqueous solution was studied using a multielectrocatalysts modified ITO electrode. ITO modification was carried out using the layer-by-layer (LBL) method, where sequential electrostatic assemblies were formed using a mu,-(meso-5,10,15,20-tetra (pirydil)porphyrin)tetrakisfbis(bipyridine)chloride ruthenium (11)} [MTRP](n+), coordinated in its central cavity with Mn(III), Zn(II) or Ni(II) as a cationic layer, and polyoxotungstate [SiW12O40](4) as the anionic layer. Electrochemical measurements and UV-vis spectroscopy were used to monitor the modification process. Optimal results were obtained when three layers were deposited onto the ITO surface and were stable in aqueous solution. The order of the multilayer formation was explored by comparing a modified electrode where [Zn(11)TRP](4+) was the outermost layer with an electrode where [SiW12O40](4) was the outer layer. Results show that the best performing electrode is one with [SiW12O40](4) as the outer layer. Nitrite reduction on these electrode surfaces was studied in dark conditions and under light irradiation. Potential controlled electrolysis experiments were also performed, finding hydroxylamine, hydrazine and ammonia as the reduction products in dark conditions. Under light irradiation, only hydrazine and ammonia were found and, we observed an increase in the amount of obtained product. In this case, the electrolysis was carried out 150 mV less and half of time than in dark conditions. These results show that the combination of light and potential give rise to an improvement in the electrocatalytic properties of the modified electrodes. Continuous photolysis and IR spectroelectrochemical experiments were carried out to determinate the nature of this phenomena, evidencing the formation of an intermediary species between nitrite and [Mn(111)TRP](5+.).FONDECYT 1141199 RC130006 3140085 1120071 3140565 315022
