Published: March 2021

Software development process involves developing, building and enhancing high-quality software for specific tasks and as a consequence generates considerable
amount of data. This data can be managed in a systematic manner creating knowledge repositories that can be used to competitive advantage. Lesson's learned as part of the development process can also be part of the knowledge bank and can be used to advantage in subsequent projects by developers and software practitioners. Code smells are a group of symptoms which reveal that code is not good enough and requires some actions to have a cleansed code. Software metrics help to detect code smells while refactoring methods are used for removing them. Furthermore, various tools are applicable for detecting of code smells. A Code smell repository organizes all the available knowledge in the literature about code smells and related concepts. An analytical study of code smells is presented in this paper which extracts useful, actionable and indicative knowledge.
Predictive Maintenance of Cash Dispenser Using a Cognitive Prioritization Model
Authors: Dixit Archana , B. Mahamun Amol
Published: March 2021

In this technical paper, we address the issue of predicting cash dispenser (addressed as ‘Device’ henceforth) failure by harnessing the power of humungous data from
service history, logs, metrics, transactions, and plausible environmental factors. This study helps increase device availability, enhanced customer experience, manage risk &
compliance and revenue growth. It also helps reduce maintenance cost, travel cost, labour cost, downtime, repair duration and increase meantime between failures (MTBF) of
individual components. This study uses a cognitive prioritization model which entails the following at its core; a) Machine Learning engineered features with highest influence on
machine failure, b) Observation Windows, Transition Windows and Prediction Windows to accommodate various business processes and service planning delivery windows, and
c) A forward-looking evaluation of emerging patterns to determine failure prediction score that is prioritized by business impact, for a predefined time window in the future. The
model not only predicts failure score for the devices to be serviced, but it also reduces the service miss impact for the prediction windows.
La microficción en las antologías: un balance crítico
Authors: Boccuti Anna
Published: March 2021

En las últimas décadas la microficción se difundido ampliamente en las letras hispánicas imponiéndose como objeto de reflexión en la crítica académica, que ha destacado su inclasificabilidad. Al cruce entre aforismo, chiste, anécdota, fragmento, la variedad de denominaciones utilizadas para indicar estos textos brevísimos – “cuentos pigmeos”, “textos hiperbreves”, “microficciones”, “minirrelatos”, “microcuentos”, “cuentos de parpadeo” – refleja de manera evidente las fluctuaciones en la determinación de sus rasgos genéricos. En este trabajo nos proponemos indagar los límites de estas oscilaciones así como aparecen en algunas antologías de microficciones, pues toda antología – en tanto que constitución de un grupo de textos derivado de un proceso de selección y organización – entraña una postulación teórica sobre la naturaleza misma de la microficción y al tiempo fija itinerarios, determinando implícitamente procesos de canonización y definición del género.

Authors: Del Río Casteñeda Laro , Benito Temprano Claudia Sofía
Published: March 2021

La viñeta ha encontrado en Instagram un espacio análogo a lo que es Facebook o Twitter para el microrrelato. La narrativa ilustrada de Flavita Banana nos sirve de ejemplo para poner en relación dos vías de expresión del microrrelato: la palabra y la imagen. Su confluencia en las viñetas de esta autora barcelonesa demuestra la riqueza expresiva, humorística y desautomatizadora de las mininarraciones ilustradas, e invita a una revaluación de los límites del género.

Las antologías de micro-biografías ilustradas sobre mujeres relevantes. Consideraciones iniciales y propuesta de aplicación.
Authors: Guadamillas Gómez María Victoria
Published: March 2021

Este artículo realiza un breve recorrido por un género en auge en los últimos años; podemos referirnos al mismo como biografías o microrrelatos ilustrados de mujeres relevantes. A partir del anterior, se propone un proyecto de aula que queda justificado gracias a los resultados obtenidos en un pre-cuestionario que confirma los escasos hábitos de lectura y escritura en lengua inglesa de los maestros en formación y, un cierto desconocimiento por parte de estos del papel de la mujer en la ciencia, el arte, la literatura o la política. Además de describir la propuesta en la que se trabaja sobre mujeres relevantes en lengua extranjera, este texto da cuenta de las posibles líneas de investigación que los resultados obtenidos nos ofrecen y, reflexiona sobre la necesidad de incluir la literatura infantil y juvenil en el aula con un propósito cultural y social que nos permita visibilizar la importancia de la mujer en diferentes ámbitos.
La función del retrato y el metateatro como microdrama en la comedia.
Authors: Frye Ellen Cressman
Published: March 2021

Este ensayo examina la función de los retratos y las situaciones metateatrales, que en algunos casos forman microdramas.  Primero, se explicará el metateatro como recurso dramático, en términos de las funciones y las subcategorías, según la investigación académica reciente, incluso el trabajo de Lionel Abel, Kate Flaherty, Richard Hornby, Manfred Pfister, Alejandro Paredes, Marnie Lange Roodi, y Bruce Wardropper.  Segundo, las comedias El vergonzoso en palacio (Tirso de Molina), y El pintor de su deshonra (Calderón), serán analizadas, prestando atención específica al uso del retrato como recurso dramático, que a veces crea un microdrama, y las múltiples situaciones metateatrales en las obras dramáticas, enfocándose especialmente en las situaciones que son microdramas.  Aquí, se citará la investigación importante en estas comedias, por ejemplo, el trabajo académico de Manuel Sito Alba, Jane Albrecht, Laura Bass, Raymond Conlon, Clark Colahan, David Darst, Frederick de Armas, and Susan Fischer.  Ultimamente, las escenas importantes de los retratos y las situaciones metateatrales significantes son microdramas, y estos microdramas ayudan en el establecimiento de la relación entre el actor y el espectador.  Sin el uso de los retratos, el metateatro, y el microdrama, no se podría desarrollar la acción dramática en estas dos comedias, no se crecería la tensión, y los espectadores no serían arrastrados al mundo dramático.

Siniestro freudiano en las Zambullidas de Yolanda Izard
Authors: Morán Rodríguez Carmen
Published: March 2021

El artículo propone un análisis de Zambullidas (2017), libro de Yolanda Izard, en el que se reúnen ochenta y cinco prosas hiperbreves marcadas por la ambigüedad genérica y la elección de un registro predominantemente no mimético, que transita entre una escritura abiertamente surrealista y un registro de lo cotidiano como escenario del desastre. Los motivos más recurrentes en la obra son, según se expone en el artículo, la fragilidad de la existencia en una realidad  lógica, la muerte asociada a la infancia, los cambios de identidad y la indagación en los aspectos más siniestros de los lazos familiares y el hogar. En el artículo se seleccionan varios ejemplos de prosas del libro de Yolanda Izard, y se analiza cómo los elementos que Freud asociaba a lo siniestro en su célebre ensayo de 1919 vienen a cumplirse en ellas.
Laminopathies’ Treatments Systematic Review: A Contribution Towards a ‘Treatabolome’
Authors: Atalaia Antonio , Ben Yaou Rabah , Wahbi Karim , De Sandre-Giovannoli Annachiara , Vigouroux Corinne , Bonne Gisèle
Published: March 2021

Background:

Variants in the LMNA gene, encoding lamins A/C, are responsible for a growing number of diseases, all of which complying with the definition of rare diseases. LMNA-related disorders have a varied phenotypic expression with more than 15 syndromes described, belonging to five phenotypic groups: Muscular Dystrophies, Neuropathies, Cardiomyopathies, Lipodystrophies and Progeroid Syndromes. Overlapping phenotypes are also reported. Linking gene and variants with phenotypic expression, disease mechanisms, and corresponding treatments is particularly challenging in laminopathies. Treatment recommendations are limited, and very few are variant-based.

Objective:

The Treatabolome initiative aims to provide a shareable dataset of existing variant-specific treatment for rare diseases within the Solve-RD EU project. As part of this project, we gathered evidence of specific treatments for laminopathies via a systematic literature review adopting the FAIR (Findable, Accessible, Interoperable, and Reusable) guidelines for scientific data production.

Methods:

Treatments for LMNA-related conditions were systematically collected from MEDLINE and Embase bibliographic databases and clinical trial registries (Cochrane Central Registry of Controlled Trials, clinicaltrial.gov and EudraCT). Two investigators extracted and analyzed the literature data independently. The included papers were assessed using the Oxford Centre for Evidence-Based Medicine 2011 Levels of Evidence.

Results:

From the 4783 selected articles by a systematic approach, we identified 78 papers for our final analysis that corresponded to the profile of data defined in the inclusion and exclusion criteria. These papers include 2 guidelines/consensus papers, 4 meta-analyses, 14 single-arm trials, 15 case series, 13 cohort studies, 21 case reports, 8 expert reviews and 1 expert opinion. The treatments were summarized electronically according to significant phenome-genome associations. The specificity of treatments according to the different laminopathic phenotypical presentations is variable.

Conclusions:

We have extracted Treatabolome-worthy treatment recommendations for patients with different forms of laminopathies based on significant phenome-genome parings. This dataset will be available on the Treatabolome website and, through interoperability, on genetic diagnosis and treatment support tools like the RD-Connect’s Genome Phenome Analysis Platform.

Published: March 2021

Panjangrejo is one of the Tourism Villages located in the east of Bantul Regency. Geographically, the location of this Tourism Village is very strategic because this Pottery Tourism Village is on one of the Parangtritis beach tourist routes, which is very crowded by tourists. Due to a lack of attention and support from the village government, the pottery craft of the Panjamgrejo tourism village is not as popular as the Kasongan village. The main problems faced by craftsmen include the stiff competition between pottery artisans, the lack of demand from outside the region due to limitations in marketing digital products (digital marketing), and the fulfillment of safe and attractive packaging. The method used in this service is the method of training and substitution of science and technology. The solution of product packaging that is still simple is overcome by procuring durable and attractive packaging boxes to increase product sales power and minimize product breakage. Also, the promotion of products that have not been run optimally is overcome by digital marketing training both through social media Instagram to Facebook ads with better internet signal support due to the availability of modems to facilitate online product marketing.

Published: March 2021

Purpose. Substantiation of the design solutions in separate units of the modernized hydromechanical devices and specification of rational technological modes of their operation in specific geological and technical conditions. Proposals on construction of wells by development and introduction of progressive methods and techniques. Methodology. Analysis of the peculiarities of the modernized hydromechanical drilling devices in terms of rock breaking is performed using modern methods of analytical analysis and experimental research, i.e. by using mathematical and physical modeling; method of modeling and processing of research results in the SolidWorks medium and others; control and measuring tools and materials. The process of solving the problems of optimal planning of the experiment was divided into four stages: development of a planned model; preparation of the necessary initial data; calculation of the model; obtaining and processing of the results. The well rock-breaking processes were modeled on a special-purpose laboratory stand equipped with a measuring and control unit (flow meter, manometer, tachometer, and coordinate spacer). Findings. The main ways to improve well hydromechanical technologies have been identified. The fundamental principles have been formulated concerning the process of design of such equipment schemes that will combine the most productive and efficient methods of the rock mass operations. A number of factors characteristic of the implementation of well hydromechanical technologies, have been identified, i.e.: rational range of physical properties of rocks according to which proper technical and technological characteristics of the devices are selected; structural use of mechanical rock-breaking organs of the devices; and operating parameters of the drilling process. It has been proved that the developed design schemes of hydromechanical drilling devices, in terms of their optimal technical performance and technological development, can be recommended for their use in the appropriate geological and technical conditions, where the implementation of other methods is inexpedient or limited. Originality. Formation of the peripheral part of the bottomhole is a subordinate factor determined by the device design; effective profiling is possible only due to the introduction of additional components into the hydromechanical drilling devices, which makes it possible to use certain technological methods. Practical value. The obtained results of laboratory and analytical studies are basic to design operating parameters of the well deepening processes by using the hydromechanical devices. Data from the study on bottomhole working processes of hydromechanical technologies are the starting point for the substantiation of design and technological parameters of modernized pellet impact devices.

The objective of the study is to simulate using numerical methods the seasonal and intraseasonal variations of circula-tion, sea level, temperature and salinity in the Bellingshausen Sea and on the shelf of the western part of the Antarctic Penin-sula (WAP). The Semi-implicit Cross-scale Hydroscience Integrated System Model with an unstructured triangular horizontal grid and a vertical local sigma coordinate system and ice dynamic-thermodynamic Finite-Element Sea Ice Model were applied. Heat, momentum and salt fluxes were set on the ocean surface using the ERA5 reanalysis data. At the open boundaries, the vertical distribution of temperature and salinity was determined according to the COPERNICUS reanalysis. At the western open boundary of the computational domain, the vertical distribution of velocity of currents from COPERNICUS was also specified, whereas at the open eastern boundary the level deviations were specified. Time variability analysis of sea level wasperformed using wavelet analysis. The results of modelling of the sea level, temperature, and salinity fields for 2014–2015 were compared with the available observational data on the shelf of the WAP, including data from the Ukrainian Antarctic Expedition. The simulated horizontal and vertical distributions of the subsurface layer with minimum of potential temperature Tmin (Winter Water) are given. The depth of the Tmin varies in the range of 10–100 m increasing to the north. The values of minimum of po-tential temperature Tmin also increase to the north from –1.8 to 1.2 °C. The intraseasonal oscillations of sea level computed by the model for 2014—2015 were analysed together with data of observations at the tidal stations Faraday/Akademik Vernadsky and Rothera located at the coast of WAP. In the range 1–150 days the largest amplitudes of the level scalegrams were found for a period of approximately 100 days in 2014 and 120 days in 2015 at both stations. The largest amplitudes of modelled level scale-grams were observed with a period of approximately 88 days in 2014 and 80 days in 2015 at both stations. The largest amplitudesof scalegrams for Antarctic Oscillation (AAO) were found for a period of 105 days in 2014 and 123 days in 2015. The corresponding correlation coefficients between observed sea level scalegrams and AAO for 2014 were 0.84 and 0.86, respectively, whereas for 2015 they were 0.87 and 0.90, respectively. It was concluded that the relationship between intraseasonal processes in the ocean in West Antarctica and AAO existed at a time scale of about 100 days.

Published: March 2021

Antarctic Peninsula region is experiencing one of the fastest rates of climate change on Earth. Its waters are known as important feeding grounds for the Antarctic minke whales (Balaenoptera bonaerensis). The purpose of the present study was to reveal the summer and early autumn presence of the Antarctic minke whales in the area adjacent to the Kiev Peninsula of West Antarctica and to estimate the encounter rates of the species in the area. The boat-based photo-identification cetacean studies were initiated as part of the long-term monitoring program based at the Akademik Vernadsky station near the Kiev Peninsula of West Antarctica. From 22 January to 7 April 2019, 35 boat and yacht cruises of the 821 nautical miles of total length were conducted. There were encountered 13 Antarctic minke whales in 7 sightings. The encounter rate was 0.015 whales per nautical mile. Minke whales were encountered only in 5% of the total sightings. Three more whales were opportunistically seen from the top of Galindez Island. There were single whales sighted and small groups of up to 3 specimens (Med = 2). At least 2 individuals were identified as juveniles. Primary behavior for whales in 7 sightings was foraging, and 2 groups were observed while travelling. A total 9 individuals of the Antarctic minke whales were photo-identified during the survey, and no matches were found between the different encounters. Our pilot study indicates summer and early autumn presence of the Antarctic minke whales in the area adjacent to the Kiev Peninsula. But encounter rates seem to be low in comparison with results of some previous surveys. Our results show the possibility to monitor minke whales in the area, and further long-term complex monitoring is essential for understanding the ecology and population dynamics of the Antarctic minke whales in rapidly changing marine environment of the Antarctic Peninsula.

Non-extractive method for the benthic wildlife study using the underwater video system (UVS) recording was provided during the research survey with the bottom longline in the northwestern part of the Weddell Sea. At the longline survey stations the data on wind direction and speed, state of the sea, air temperature, cloudiness, ice concentration, atmospheric pressure, precipitation, depth and coordinates of the anchor setting, direction of the longline set also were collected. It was found that the UVS with additional light during video recording does not disturb the animal behavior at depths of 700–1100 m in the study area. Three UVS observations have been described. The slope of the northwestern part of the Weddell Sea can be considered as spawning site of squid (Slosarczykovia circumantarctica). The data indicate wide distribution of Antarctic krill (Euphausia superba) and Antarctic jonasfish (Notolepis coatsi) in the area. The high density of the adult Antarctic jonasfish in a single place has never been recorded before. Preliminary observations and analysis of video recordings showed that the shooting lighting andobservation distance are sufficient for observing and identifying animals, their behavior and movement. This technique will allow estimating the relative species abundance and size distribution.
Terrestrial ecosystems of the Antarctic Peninsula and their responses to climate change and anthropogenic impacts
Authors:   University of Siena, Bargagli R.
Published: March 2021

Antarctica and the Southern Ocean are unique natural laboratories where organisms adapted to extreme environmental conditions have evolved in isolation for millions of years. These unique biotic communities on Earth are facing complex climatic and environmental changes. Terrestrial ecosystems in the Antarctic Peninsula Region (APR) have experienced the highest rate of climate warming and, being the most impacted by human activities, are facing the greatest risk of detrimental changes. This review provides an overview of the most recent findings on how biotic communities in terrestrial ecosystems of the Antarctic Peninsula Region (APR) are responding and will likely respond to further environmental changes and direct anthropogenic impacts. Knowledge gained from studies on relatively simple terrestrial ecosystems could be very useful in predicting what may happen in much more complex ecosystems in regions with less extreme temperature changes. The rapid warming of the APR has led to the retreat of glaciers, the loss of snow and permafrost and the increase of ice-free areas, with a consequent enhancement of soil-forming processes, biotic communities, and food web complexity. However, most human activity is concentrated in APR coastal ice-free areas and poses many threats to terrestrial ecosystems such as environmental pollution or disturbances to soilcommunities and wildlife. People who work or visit APR may inadvertently introduce alien organisms and/or spread native species to spatially isolated ice-free areas. The number of introduced non-indigenous species and xenobiotic compounds in the APR is likely to be greater than currently documented, and several biosecurity and monitoring activities are therefore suggested to Antarctic national scientific programs and tourism operators to minimize the risk of irreversible loss of integrity by the unique terrestrial ecosystems of APR.

Difficulties of management, along with the lack of chemical fungicides officially registered by the Ministry of Agriculture, Livestock and Supply (MAPA), require alternative control methods. This study investigated the in vitro antagonistic activity of Trichoderma harzianum as well as a biological fertilizer MICROGEO® on Fusarium solani. The phytophatogenic strains of F. solani, called F1 and F2 were isolated from rotted cassava tubers and T. harzianum, strain ESALQ 1306, from a biological fungicide. Continuous liquid composting of bovine ruminal content, water and MICROGEO® produced the biological fertilizer. Dual culture method was used at the bioassay with T. harzianum. Sterilized (St) and unsterilized (USt) biological fertilizer were tested in different concentrations (% v/v) diluted in the culture media. Colony diameters were measured daily in order to establish the mycelial growth velocity index, inhibition percentage, aside from the sporulation rate and spore germination percentage. The mycelial growth of F. solani isolates was interrupted after hyphae encounter with T. harzianum, due to the occurrence of mycoparasitism, but without influence on the sporulation rate. Sterilized biological fertilizer induced no biocontrol, whereas the unsterilized product (concentration 2.5%) inhibited approximately 64% and 85% of the mycelial growth of isolates F1 and F2, respectively. Moreover, spore germination declined with increasing concentration. In conclusion, T. harzianum and the unsterilized biofertilizer showed in vitro antagonistic activity on F. solani.
Arnold J. Toynbee, the Colonial Question, and ‘Peaceful Change’
Authors: Venosa Robert D.

While most scholarship on appeasement focuses on its later stages in Europe – culminating in the Munich Agreement – policymakers and public intellectuals throughout the early and mid-1930s were exercised by appeasement in a different context. These prominent Britons, concerned by increasing international tensions and conscious of the resentments engendered by having a globe-spanning empire, sought to contrive some way to appease the revisionist powers without betraying their liberal internationalist principles or harming British national interests. At the center of these debates was Arnold J. Toynbee, director of studies at Chatham House. A devoted liberal internationalist, Toynbee was convinced that a durable peace could be built on appeasement in the context of ‘the colonial question’. This version of appeasement claimed that German interests and honour could be satisfied by finding some way to return Germany to Africa as an imperial power. But the debates over ‘the colonial question’ revealed the extent to which British and German conceptions of the issue diverged. They also demonstrated the inability of liberal internationalists to reconcile their commitment to changing an unsatisfactory status quo with their commitment to preventing the forceful revision of that same status quo; ‘peaceful change’ was therefore elusive.

A familiáris hypercholesterinaemia (FH) a koleszterin-anyagcsere veleszületett zavarával járó kórkép, amelyet jelentősen emelkedett összkoleszterinszint (TC) és low density lipoprotein koleszterinszint (LDL-C), ennek következtében a szív- és érrendszeri betegségek korai megjelenése jellemez. A magas vérnyomás előfordulási gyakorisága FH-s betegekben nem tisztázott, de jelenléte független kockázati tényezője a cardiovascularis betegség kialakulásának. Megfelelő terápiája ezért kiemelt fontosságú ebben a nagy kockázatú betegcsoportban.Célul tűztük ki 86, szakrendelésünkön először megjelent, frissen diagnosztizált, lipidcsökkentő kezelésben még nem részesülő heterozigóta FH-s beteg (27 férfi, 59 nő, átlagéletkoruk 53,6±13,4 év) esetén a lipidszintek, valamint a dokumentáció alapján a magas vérnyomás előfordulásának és kezelésének értékelését. Az FH diagnózisát a Dutch Lipid Network kritériumrendszer alkalmazásával állítottuk fel.A betegek átlagos TC-szintje 8,49±1,7 mmol/l, átlagos LDL-C-szintje 6,11±1,5 mmol/l, átlagos high density lipoprotein koleszterin (HDL-C) szintje 1,62±0,5 mmol/l, míg a lipoprotein-(a)-szint mediánja 301 mg/l volt. Mindössze 33 beteg esetén diagnosztizáltak korábban magas vérnyomást (38,4%). Béta-blokkolót 23, ACE-gátlót 13, ARB-t 12, kalciumcsatorna-blokkolót 9, HCT-t 11 beteg kapott. 11 beteg részesült monoterápiában, 10 beteg kettős, 11 beteg hármas, míg 1 beteg négyes kombinált kezelést kapott.Az eredmények alapján a magasvérnyomás-betegség ebben a betegcsoportban valószínűleg aluldiagnosztizált, a javasolt kezelés pedig sem az alkalmazott szer típusát, sem annak módját tekintve nem felelt meg az aktuális terápiás irányelveknek. A magasvérnyomás-betegség szűrése és korszerű kezelése, tekintettel az FH esetén kialakuló korai érelmeszesedésre, jóval nagyobb figyelmet érdemel ebben a kiemelt kockázatú betegcsoportban.

Natamycin (NAT) is the drug of choice for the treatment of fungal keratitis (FK). However, its inherent shortcomings, such as poor solubility, high dosing frequency, and long treatment cycle, need to be urgently addressed by designing a new delivery to widen its clinical utility. Growing research has confirmed that clotrimazole (CLZ) plays a significant role in fungal growth inhibition. Hence, coaxial electrospray (CO-ES) technology is used herein to prepare nano-systems with an average hydrodynamic particle size of 309-406 nm for the co-delivery of NAT and CLZ in chitosan (CTS) and poly(lactic-co-glycolic acid) (PLGA). The resulting NAT/CLZ@CTS/PLGA formulations were characterized by a transmission electron microscope (TEM) and in vitro release test. The results show that the formulations had obvious core-shell structures, uniform particle distribution, and also can sustain the release of drugs over 36 h. Furthermore, in vitro hemolysis, in vivo corneal irritation test, local allergenic test, and antifungal activity analyses are performed to evaluate the safety and efficiency of the formulations. Thus, good biosafety along with a significant anti-candidiasis effect are found in the NAT/CLZ@CTS/PLGA nanoparticles (NPs). Taken together, the results suggest that this design may provide a promising drug delivery system and a new option for the treatment of FK.

The reported haploid Saccharomyces cerevisiae strain F106 can utilize xylose for ethanol production. After a series of XR and/or XDH mutations were introduced into F106, the XR-K270R mutant was found to outperform others. The corresponding haploid, diploid, and triploid strains were then constructed and their fermentation performance was compared. Strains F106-KR and the diploid produced an ethanol yield of 0.45 and 0.48 g/g total sugars, respectively, in simulated corn hydrolysates within 36 h. Using non-detoxicated corncob hydrolysate as the substrate, the ethanol yield with the triploid was approximately sevenfold than that of the diploid at 40°C. After a comprehensive evaluation of growth on corn stover hydrolysates pretreated with diluted acid or alkali and different substrate concentrations, ethanol yields of the triploid strain were consistently higher than those of the diploid using acid-pretreatment. These results demonstrate that the yeast chromosomal copy number is positively correlated with increased ethanol production under our experimental conditions.
