Study design: Technical note.
Objectives: To present a novel technique of treatment for patient with basilar invagination.
Background : Basilar invagination (BI) is considered a congenital condition and can compress the cervicomedullary junction, causing neurologic deficit. Severe neurological deficit due to BI should be treated surgically. However, there is controversy regarding whether an anterior or posterior approach should be used. Anterior approach is optimal for decompression of cervicomedullary junction, but this approach has high complication rates. Posterior reduction has a high risk of occipital screws backout and/or instrument failure.
Materials and Methods : A 15-year-old boy with severe myelopathy was referred to our hospital. He had neck pain, muscle weakness of bilateral upper limbs, gait disturbance appeared 3 months before he visited our hospital, he drops a cup several times recently. In the examination, he had hyperreflexia of upper and lower limbs and muscle weakness of bilateral arms (MMT 4), hypoesthesis was observed bilaterally below elbow and both legs. He also had clumsiness of bilateral hands, mild urinary and bowel incontinence, and spastic gait. His 10 second grip and release test was 16 in both hands. His grip power was 20 kg in right and 17 kg in left. Radiograms showed severe BI and spinal cord was severely compressed with odontoid process..
Results : The patinet underwent posterior surgery with C-arm free technique. All screws including occipital screws were inserted adequate position under navigation guidance. Reduction was achieved with skull rotation and distraction. A follow-up at one year we have these results : Manual muscle testing results and sensory function tests showed almost full recovery, bilateral arms (MMT 5) ,walking smoothly. Cervical Japanese orthopedic association score of the patient has improved from 9/17 to 16/17. Post-operative images showed an excellent spinal cord decompression, and no major or severe complications has occured .
Conclusions/Level of Evidence : Basilar invagination with Klippel-Feil syndrome is relatively rare condition. Posterior approach and occipito-cervical fixation for BI treatment with navigation technique is a safe method to treat severe myelopaty with reducible odontoid. This novel navigation technique provides an excellent results for a patient with BI. Level V.

Published: February 2024

Online teaching is considered an important approach for achieving sustainable learning and education, and college teachers’ attitude and behavioral intention are essential for the sustainable adoption of online teaching practice in higher education institutions. To examine the influencing factors that sustain teachers’ attitude toward online teaching and behavioral intention, we conducted a cross-sectional study based on a sample of 1,102 college teachers in central China, using hierarchical linear regression analysis to explore possible influencing factors in four levels: individual experience, environmental support, self-perception, and technology acceptance. The study results show that the subjective norms, readiness, beliefs, and perceived usefulness of online teaching had a significant impact on teachers’ attitude toward online teaching and behavioral intention. Nevertheless, the effect varied with factors like online-teaching load and teachers’ technology self-efficacy, as their influence seemed to be singular, affecting the teachers’ attitude toward online teaching or behavioral intention exclusively. In contrast, previous online-teaching experience did not notably affect either. The findings of this study reveal the complex interactions of factors that influence college teachers’ disposition toward and decisions about online-teaching practices and emphasize the need for targeted strategies to maintain and enhance online education in the post-pandemic era.

Published: February 2024

The clinical neurophysiological tests allow determine the type, extent, and nature of brachial plexus damage. They are crucial in decision-making regarding surgical procedures or conservative treatment. This report aimed to present an algorithm for rehabilitation procedures in patients with brachial plexus injury of various origins based on the results of neurophysiology findings for the selection of procedures supporting the process of nerve and muscle regeneration. The research group consisted of patients whose medical documentation was analyzed concerning the reason, level, and localization of damage to the brachial plexus structures, surgical and or rehabilitative treatment as well as the MRI results. Among the group of ten patients, the clinical studies showed the greatest incidence of brachial plexus injuries of the mixed (both pre- and postganglionic), all trunks, and cervical root injuries, respectively. Results of the motor evoked potentials (MEP) and electroneurography (ENG) recordings induced at levels of spinal roots and Erb's point showed a decrease of more than 40% in amplitudes on the symptomatic side in comparison to the asymptomatic side. This difference was recorded for the axillary and radial innervation and the C5, C6, and C7 root domains, ranging from 56% to 71%; the lowest decrease was recorded following electrical stimulation at Erb's point for the ulnar nerve (41.5%). The latency prolongation on the symptomatic side in CMAP and MEP tests ranged from 0.2 to 1.9 ms, the most following magnetic stimulation of the C5 cervical root for the axillary innervation. All results indicated the axonotmesis and neuropraxia type of injury in motor fibers (40%) confirmed by EMG results. The sensory conduction studies (SNCS) in distal nerve branches did not confirm the severe advancement of the brachial plexus injury (22%). The proposed algorithm of the physiotherapeutic procedures should be mainly targeted for recovery of motor dysfunction as the consequence of brachial plexus injury. Rehabilitation should incorporate the treatment supporting nerve regeneration, muscle strengthening, and maintaining functional ranges of motion of the injured extremities. The rehabilitation treatment for patients with brachial plexus injuries is an individualized process, and the selection of procedures and the effectiveness of the treatment undertaken should be confronted with results of neurophysiological tests verifying the motor neural transmission from the level of the cervical motor center to the effector, peripheral nerve function, and muscle’s motor unit activity.

Published: February 2024

To stabilize the Earth’s climate a large-scale transition is needed to non-carbon emitting renewable energy technologies like wind and solar energy. Although these renewable energy sources are now lower-cost than fossil fuels, their inherent intermittency make them unable to supply a constant load without storage. To address these challenges rechargeable electric batteries are currently the most promising option; however, their high capital costs limit current deployment velocities. To both reduce the cost as well as improve performance 3D printing technology has emerged as a promising solution. This literature review provides the state-of-the-art enhancements of battery properties with 3D printing including efficiency, mechanical stability, energy and power density, customizability and sizing, production process efficiency, material conservation and environmental sustainability as well as the progress in solid-state batteries. The principles, advantages, limitations, and recent advancements associated with the most common types of 3D printing are reviewed focusing on their contributions to the battery field. 3D printing batteries offer design flexibility, material flexibility, reduces pack weight, minimizes material waste, increases the range of applications and has the potential to reduce costs. As 3D printing technologies become more accessible, the prospect of cost-effective production for customized batteries is extremely promising.

Published: February 2024

Continuum robots play the role of end-effector in various surgical robots and endoscopic devices. The robots may be categorized as rigid or soft continuum robots (SCRs). While the SCRs have proven advantages such as safety and compliance, more research and development are required to enhance their capability for specific medical scenarios. This research aims at designing a soft robot considering concepts of geometric and kinematic similarities. The chosen application is a semi-invasive medical application known as Transesophageal Echocardiography (TEE), but the methodology can be implemented in other similar applications. Since established rigid carrier construction make use of principles we find as well embodied in vertebral spines, the paragon for soft robot solution can be the phylogenetic precursor of the spine, the Chorda dorsalis. The feasibility of fabrication of a soft endoscopic device derived from that paragon within a robotics laboratory was shown empirically by producing a three-segment pneumatic SCR. The kinematic model was proposed based on the method of transformation matrices, and an algorithm based on a self-organizing map (SOM) was proposed and applied to realize kinematic similarity. The simulation results indicate that the algorithm acting as an open-loop controller forces the soft robot tip to follow the desired path which in this case is the path of the rigid probe. It is concluded that the solution provides a soft robot that can surrogate and succeed the traditional rigid counterpart owing to size, workspace, and kinematics.
Controllable Spatial Array of Bessel-Like Vortical Optical Needles With Different Topological Charges and Locations in the Transverse Plane
Authors: Šlevas Paulius , Orlov Sergej
Published: February 2024

Bessel vortices generated via axicons are widely used for various applications like optical tweezers or laser microfabrication of transparent materials. The specific intensity profile having high aspect ratios of beam width and length, in turn, generates a high aspect ratio void that resembles an optical needle or an optical bottle. In contrast to commonly generated Bessel vortices, which have a fixed axial intensity distribution. We present a novel method for engineering Bessel vortices that can have an arbitrary axial intensity distribution via superposition of different cone-angle Bessel vortices. We analytically describe spatial spectra of optical needle-like vortices having an arbitrary axial intensity distribution. We also demonstrate a superposition of independent optical Bessel-like vortices and analyze the physical limitations to observe well-separated optical needles as they are influenced by mutual interference of the individual beams. To verify our theoretical and numerical results, we generate controllable spatial arrays of individual beams with various numbers and spatial separations by altering the spectrum of the incoming laser beam via the spatial light modulator. Lastly, we numerically examine distortions caused by propagation through the planar air-dielectric interface and show the compensation method by appropriately modifying the spectral masks.
Unraveling the Complex Pathology of Neurodegenerative Diseases: Multiple Prions, Cross-β Networks and Baicalein's ReproFold
Authors: Chang Hsiang-Yu , Wang I-Fan
Published: February 2024

The origin of neurodegenerative diseases is linked to the abnormal folding of disease-associated proteins. The traditional amyloid hypothesis has been a focal point of research, but recent findings suggest a more complex picture. This review explores the role of physiological conformation of aggregation-prone domain (also known as prion-like low complexity domain) and multiple co-misfolded proteins in neurodegenerative diseases. We highlight the importance of targeting multi-heterotypic misfolded proteins for effective treatments and emphasize the irreversible neurodegeneration stemming from the loss of physiological folding in prion-like disease-causing proteins underscores the criticality of refolding. Additionally, we introduce the concept of ReproFold Therapeutics, a novel approach aimed at restoring the cellular prion-like folding of disease-causing proteins to rebuild normal cross-β interactomes and mitigate neurodegeneration. Baicalein, a potential drug candidate for this approach, shows promise in vitro and in animal models. Moreover, prion-like low complexity domains implicated in neurodegeneration are also associated with other disorders such as diabetes, cancers, and mental illnesses. Understanding the core pathology of neurodegenerative diseases and the broader implications of prion-like LC domains could revolutionize healthcare approaches and policies worldwide.

Published: February 2024

Objectives. To identify potential drivers of health care worker attrition.

Methods. We conducted a survey of 1083 nonphysician health care workers in a large urban health system in New York City from September to October 2022.

Results. The results of a multivariable logistic regression analysis revealed that higher odds of intending to leave health care were significantly associated with male gender, registered nurse profession, burnout, self-perceived mental health service need, and verbal abuse from patients or visitors, whereas lower odds were seen among those reporting greater emotional well-being and a better workplace culture. A relative importance analysis indicated that burnout was the strongest correlate of intention to leave (22.5% relative variance explained [RVE]), followed by subjective emotional well-being (16.7% RVE), being a registered nurse (12.3% RVE), poorer perceived workplace culture (9.5% RVE), and male gender (5.9% RVE).

Conclusions. Overall, our findings suggest the need for well-coordinated interventions that address both individual- and system-level factors in an effort to improve retention.

Public Health Implications. Our results indicate a need for interventions targeting workplace culture, staff burnout, and mental health service provision. ( Am J Public Health. 2024;114(S2):S200–S203. https://doi.org/10.2105/AJPH.2024.307574 )
Calculation and Analysis of Specific Losses of Active Power in Overhead Power Lines due to Corona in View of Climatic Data
Authors: Sekatski D. A. , Papkova N. A.
Published: February 2024

. It is a very challenging task to correctly use weather data to calculate the active power loss due to corona in overhead power lines. One of the significant reasons for this was the problem of accuracy of determining weather conditions and the use of the forecast for calculating extended overhead lines. In the USSR (Union of Soviet Socialist Republics), based on field tests and experimental data, recommendations were developed for accounting for losses of electric energy due to corona and interference in overhead lines, the average values of which were given in the relevant instruction for the regulation and justification of the norm of electricity consumption for its transmission over electric networks. According to this regulatory document, the specific cost of active power due to corona in overhead lines, averaged by design, was determined depending on weather conditions, which were divided into four groups. In this paper, the effect of active power losses on corona is estimated using various factors on the example of high-voltage overhead lines in the main electrical networks of the Republic of Belarus of various rated voltages. Dependences of active power losses due to corona have been constructed and modeled, taking into account different climatic and weather conditions observed in the country. The determination of metrological parameters was based on the analysis of weather data and patterns of types of weather conditions. In order to improve the accuracy of calculating the specific losses of active power due to corona, all possible weather conditions were considered, as well as their combinations. Afterwards, the data on weather conditions were processed and their types were reduced to one of the four existing types of weather. A method for determining electric power losses due to corona in overhead lines based on the average relative air density and geometric parameters of the predominant section of overhead lines has been proposed and presented. It is shown that the usage of exclusively rated voltage can cause errors in determining both the specific and actual values of active power losses for corona.

Published: February 2024

To solve the problem of useful utilization (by combustion in heat generators) of liquid and gaseous industrial waste (that was defined in Part 1 of the present article), heat transfer processes in heat generating units were considered in Part 2. The main equipment for the effective solution of this process is a burner device and a combustion chamber with heat transfer to an external heat carrier, for example, a boiler furnace or a heat recovery boiler. The present article considers an example of calculating such a process for a distinctive mixture of waste from a chemical industry enterprise using modeling of possible schemes of a flame combustion system for a characteristic combination of various types of gaseous and liquid combustible products. For this purpose, the CFD (Computational Fluid Dynamics) computational hydrodynamics method was applied, which is determined to be the most effective one, in analyzing the behavior of media flows and combustion processes. CFD analysis makes it possible to predict hydrodynamic and thermal processes (especially in complex multicomponent systems) and optimize them to achieve the best results. The most important factor in high-quality combustion is the atomization process (fine atomization) of highly viscous liquids with high surface tension coefficients. The ultrasonic me-thod has been adopted as the most effective for such liquids. Besides, the quality of the distribution of flows of combustion mixtures and flue gases in the combustion chamber is considered. For doing this, it is necessary to arrange separate flows of axial and peripheral air, which make it possible not only to change the configuration of the flame, but also to direct convective flue gas flows to the most efficient areas of the combustion chamber. The article considers various options for heat transfer (convective and radial) depending on various factors, taking into account the degree of probability of formation of pollutants (primarily NOx) in combustion products. The results of the numerical solution of the problem are presented. The analysis of the results on the optimal ratio of the shares of primary and secondary air flows for combustion was carried out. In conclusion, a comparative analysis of the options for burning fuel directly in the boiler and in the pre-combustion chamber is presented. The efficiency of direct combustion has been demonstrated.
Determining of the Maximum Throughput of Control Valve in Heat Supply Systems
Authors: Sukhotski A. B.
Published: February 2024

Providing consumers with heat of the required quality in the required quantity is quitea tall order. This is due to various laws of time variation in thermal loads of residential, public and industrial buildings, and the high inertia of district heating systems. Currently, new technical capabilities have appeared that make it possible to implement methods of quantitative and qualitative regulation of heat load in heat supply systems, which have a number of advantages over qualitative regulation. Based on the equations of heat transfer, thermal and hydraulic balance, the article shows the interactions between the parameters of various types of heat supply systems, viz. valve opening degree, throughput capacity, flow rate, and coolant temperature. The type of flow characteristics of the control valve, temperature characteristics of heat supply systems, temperature control characteristics, thermal and hydraulic characteristics of the regulated area are determined. The purpose of the article was to consider the influence of the maximum throughput capacity of the control valve on the thermal and hydraulic characteristics of dependent and independent water heating systems. As a result of the analysis of the thermal and hydraulic characteristics of heating systems, recommendations have been developed for selecting valve parameters to ensure high-quality temperature control. For independent heat supply systems with a heat exchanger, it is recommended to install a control valve with a concave (logarithmic, parabolic or other) characteristic. In the case of installing a valve with a linear characteristic, the heat exchanger throughput capacity need to be greater than the maximum throughput capacity of valve (the pressure loss of the medium flow in open valve is higher than the pressure loss in the heat exchanger). For dependent heat supply systems, it is recommended to install a control valve with a linear characteristic and a maximum throughput capacity five times less than the throughput capacity of the jumper.
Axisymmetric Pressing Problem of Discrete Metal Materials
Authors: Dyakonov O. M. , Litvinko A. A.
Published: February 2024

The paper presents an analytically closed solution to the problem of axisymmetric pressing of discrete metal materials by the method of jointly solving the differential equations of equilibrium of the metal and the plasticity conditions of the porous body, taking into account all pressing factors without exception: the type and properties of the charge, loading conditions, porosity, temperature, friction, etc. The purpose of this work is to develop the foundations of the engineering theory of pressure processing of discrete materials using the example of solving the problem of axisymmetric pressing of structurally inhomogeneous metal chips in a movable closed matrix. The basis for constructing a physical and mathema-tical model of the process is the idealized case of uniform compaction of a porous body with the subsequent determination of the lateral pressure coefficient corresponding to the actual degree of compaction at various stages of loading. The resulting equation for the relationship between the stress tensor components and the yield stress and relative compaction density represents the cylindrical Mises plasticity condition, which in the limit at zero porosity transforms into the plasticity condition for compact metals. The boundary value problem is solved for tangential stresses, taking into account the magnitude and direction of action of contact friction forces, which in their physical nature do not differ from the friction forces in the depth of the pressed material. The physico-mathematical model makes it possible to calculate the stress fields and density of the body according to the coordinates of the deformation zone, as well as energy-power parameters (pressure, force, work of deformation) provided that three structural and rheological characteristics are determined: the yield strength, relative compression and the degree of deformation compaction. Due to the fact that the problem is solved in relation to bodies of rotation in a general form and in a general formulation, the solution itself should be considered as methodological for any axisymmetric loading scheme.

Published: February 2024

In the long term, along with the growth of nuclear power and related changes in the fuel and energy balance of the country, natural gas will retain an important place in the national economy, including in the production of heat and electricity Accordingly, the importance of gas distribution networks, which directly supply fuel to the Republic's consumers, will remain for a long time. According with the Concept of the National Strategy for Sustainable Development of the Republic of Belarus for the period until 2035, the main task in the gas sector is to maintain production assets at a level ensuring safe energy supply. Practice shows that corrosion factor has the greatest potential to influence the technical condition of steel underground distribution gas pipelines. To compensate for corrosion processes, steel underground pipelines are equipped with special protective means, in particular, insulation coatings. One of the key operational characteristics of  insulation is its integrity, which is controlled through periodic (comprehensive) instrumental technical inspection. Based on the inspection results, statistics of  identified defects of protective coatings is formed. The work examines the issues of ensuring the reliability of operational data, and highlights the experience of implementing specialized software packages in gas supply organizations of the Beltopgaz State Production Association for recording and processing the results of instrument surveys of gas distribution pipelines. The issue of the influence of organizational and production aspect (features of technology, local practice of planning and performing specific types of work on technical operation) on the structure of operational data, which requires separate study and accounting for their further statistical processing and use, has been considered in the paper.
University as a Driver of New Industrial Policy of Russia: Efficiency Evaluation (Using the Case of National Research University of Electronic Technology)
Authors: Dobrynina M. V. , Rastimeshina T. V.
Published: February 2024

Development of higher education institutions within the framework of the “University 3.0” paradigm is actively analyzed in the research community of Russia, Belarus and Euroasian Economic Community countries. However, a small number of scientists are trying to give a comprehensive assessment of the role of Russian universities in achieving the goals of new industrial policy. The paper presents the results of a study aimed at filling this gap. The purpose of the study was to evaluate the efficiency of higher education institutions in the context of their contribution to achieving the goals of the new industrial policy (using the example of key development indicators of the National Research University of Electronic Technology (MIET). During the study, the following tasks have been solved: a brief overview of the main scientific publications covering the research issue was completed; the content and main directions of the new industrial policy were analyzed; the role of universities as key elements of the institutional mechanism of the new industrial policy has been revealed, through the implementation of which universities carry out it. A hypothesis has been put forward about imbalance of two key areas of development of leading Russian research universities in terms of their participation in increasing the economic power of Russia. Based on the analysis of the main indicators of the development of the National Research University of Electronic Technology (MIET) it has been demonstrated that significantly more time and resources is devoted to expanding the pre-sence of this university in national science and industry than to improving the quality of educational programs and introducing the results of innovative activity into work with students and graduate students. Conclusions have been made that theoretical model and practical ways and means for transporting resources, innovative solutions and innovation energy in the educational space are not sufficiently explored. Practical recommendations for educational institutions are formulated: it is proposed to involve industrial enterprises more widely not only in accreditation, but also in the implementation of educational programs (including such elements as internships and internships at industrial enterprises). This approach will help to strengthen the effects of the triple spiral of innovation in the training of engineering personnel for the real sector of the economy

Published: February 2024

Mathematical models for controlling centrally oriented and non-centrally oriented rotary wheels of a mobile robot are considered. Based on the analysis of the kinematics of the mobile robot, the dependences of the rotation angle of the rear and front free wheel on the angular velocities of the right and left differentially driven drive wheel were obtained. For a specific mobile robot with certain kinematic parameters, graphs of the dependences of the angle of rotation of the free wheels on the radius of rotation of each wheel and graphs of the dependences of the angle of rotation of the free wheels on the angular velocities of the driving wheels were constructed. The results obtained made it possible to establish a pattern between the angle of rotation of the castor wheels and the design characteristics of the robot. A certain range of angular velocities of the driving wheels in accordance with the limiting values of the caster wheel rotation angles makes it possible to take into account the obtained mathematical models to increase the stability of the movement of the mobile robot.
Analysis of algorithms for detecting traffic incidents on highways using stationary vehicle detectors
Authors: Navoi D. V. , Kapski D. V. , Filippova N. A. , Pugachev I. N.
Published: February 2024

Incident detection algorithms from an automation point of view can be divided into two categories: automatic and non-automatic incident detection. Automatic algorithms refer to those algorithms that automatically identify an incident based on traffic flow data received from traffic detectors. Manual algorithms or procedures rely on reports from human witnesses. Based on functional characteristics, incident detection algorithms are divided into algorithms for highways and algorithms for street networks. Based on data acquisition methods, incident detection algorithms are divided into three groups: algorithms using data from stationary vehicle detectors (inductive loops, radars, video cameras, etc.); algorithms using mobile sensors (Bluetooth, wi-fi RFID, GPS, Glonass sensors, toll system transponders, etc.). algorithms that use information from drivers (GSM communications, navigation services, Internet applications, etc.). This article discusses algorithms that use data from stationary vehicle detectors. The disadvantages of incident detection algorithms using stationary transport detectors include: the need to install and operate transport detectors (inductive, video, etc.) leads to interference with traffi fl and sometimes to temporary closure of traffic The location of installation of vehicle detectors, the frequency of their installation and the number are critical from the point of view of detecting an incident on a particular section of the highway. However, it is extremely labor and capital-intensive to install stationary detectors along the entire length of the highway. Also, inductive vehicle detectors, which are mainly used to determine the parameters of traffic flow on highways, are unreliable and often fail, which makes it ineffective to detect incidents on a particular section of the road. The advantages of the algorithms under consideration include their proven reliability and accuracy in identifying incidents over decades, which is their undoubted advantage over algorithms that use mobile sensors or information from drivers.

El presente trabajo de investigación fue de tipo observacional, transversal, retrospectivo y descriptivo, y se realizó con el objetivo de determinar la frecuencia de hipodoncia hallada mediante radiografías panorámicas en pacientes de 7 a 15 años que acudieron al Instituto de Diagnóstico Maxilofacial (IDM) en el periodo entre el 2016 hasta el 2020. El tamaño muestral estuvo constituido por 400 radiografías panorámicas seleccionadas de manera aleatoria, las cuales fueron analizadas una por una mediante su proyección en una computadora, en este análisis se evaluó la hipodoncia según el tipo de pieza dentaria, el número de piezas dentarias afectadas, maxilar, frecuencia de hipodoncia según la edad y sexo. Posterior al análisis, se obtuvo que la frecuencia de hipodoncia fue de 8.5%. El segundo premolar fue la pieza con mayor frecuencia de hipodoncia con un 58.8% seguido de los incisivos laterales con un 26.5%. De acuerdo al número de piezas dentarias con hipodoncia, la mayor frecuencia fue de 44.1% en pacientes con una pieza dentaria afectada, seguido de un 38.2% correspondiente a pacientes con dos piezas dentarias afectadas. En el maxilar inferior se reportó la mayor frecuencia de hipodoncia con un 57.38%. La edad donde hubo mayor frecuencia de hipodoncia fue en el grupo de pacientes entre los 13 a 15 años con un 52.9%. Con respecto al sexo, la frecuencia de hipodoncia fue mayor en el sexo femenino con un 55.9% y menor en el sexo masculino con un 44.1%.

Los biocombustibles son la alternativa mas rápida de implementación para reducir la alta dependencia de combustibles fósiles y la reducción de las emisión de gases de efecto invernadero que estos producen. El bioetanol a partir de la biomasa lignocelulósica podría ser un sustituto de la gasolina. Este estudio evaluó la eficiencia de Saccharomyces cerevisiae y Zymomonas mobilis en la fermentación de los residuos de mandarina (Citrus nobilis). Se comparó la producción de bioetanol usando S. cerevisiae, Z. mobilis y la asociación de ambos. El cultivo se realizó por triplicado en un biorreactor casero. Los resultados mostraron el rendimiento óptimo de bioetanol después de 120 h de fermentación, obteniéndose 7,0 %v/v, 4,2 % v/v y 1,9 %v/v a partir de la asociación, S. cerevisiae y Z. mobilis, respectivamente. La asociación produjo los mayores rendimientos en la producción de bioetanol, (0,35 g-etanol/g-glucosa), mayor eficiencia de conversión de azúcares a bioetanol (67,68 %) y mayor productividad volumétrica (1,30 g/L/h). Los hallazgos de este estudio sugieren que los residuos de mandarina contienen azúcares fermentables favorables y representan una oportunidad para la producción de bioetanol.
