Authors: Chávez Gutiérrez Natalia Aidé , López de Santana Pimienta Job Alfonso , Juárez Méndez Juan 
Published: May 2023

El cerezo (Prunus avium L.) es un cultivo con baja superficie plantada en México, durante el año 2019 se produjeron 92 toneladas y existe una demanda de 1,249 toneladas que se abastece mediante importaciones provenientes de Chile y Estados Unidos (FAOSTAT, 2022). La zonificación agroecológica es una herramienta que se utiliza para determinar zonas potenciales para el establecimiento de cultivos. El objetivo principal de la investigación fue determinar la zona potencial de producción para el cerezo en la región manzanera del Estado de Chihuahua desde un punto de vista agroecológico, esta determinación se realizó mediante el uso de un sistema de información geográfica (SIG), el cual facilitó la manipulación y sobreposición de capas de información, correspondiente a factores climáticos, edáficos y biológicos. Se utilizaron datos diarios de información climática de 10 estaciones meteorológicas durante un periodo de 20 años (2000 – 2021), con el uso de ésta información se desarrollaron las unidades calor, horas frío y unidades frío y precipitación en la región manzanera; para la información edafológica y biológica se utilizaron cartas edafológicas del Instituto Nacional de Estadística, Geografía e Informática (INEGI). Se generó la zonificación agroecológica mediante una clasificación de las variables: pendiente, textura, pedregosidad, uso de suelo y vegetación, unidades frío, unidades calor, horas frío y precipitación en función de los requerimientos del cultivo y su importancia para el desarrollo del cerezo para obtener las zonas aptas potenciales del cerezo.
A Machine Learning–Based Approach to Time-series Wave Identification in the Solar Wind

Published: May 2023

Abstract
The Wind spacecraft has yielded several decades of high-resolution magnetic field data, a large fraction of which displays small-scale structures. In particular, the solar wind is full of wavelike fluctuations that appear in both the field magnitude and its components. The nature of these fluctuations can be tied to the properties of other structures in the solar wind, such as shocks, that have implications for the time evolution of the solar wind. As such, having a large collection of wave events would facilitate further study of the effects that these fluctuations have on solar wind evolution. Given the large volume of magnetic field data available, machine learning is the most practical approach to classifying the myriad small-scale structures observed. To this end, a subset of Wind data is labeled and used as a training set for a multibranch 1D convolutional neural network aimed at classifying circularly polarized wave modes. Using this algorithm, a preliminary statistical study of 1 yr of data is performed, yielding about 300,000 wave intervals out of about 5,000,000 solar wind intervals. The wave intervals come about more often in the fast solar wind and at higher temperatures, and the number of waves per day is highly periodic. This machine learning–based approach to wave detection has the potential to be a powerful, inexpensive way to catalog waves throughout decades of spacecraft data.

Authors: Şen Özdemir N. , Koyun M. , Caf F. , Kırıcı M. 
Published: May 2023

This study aimed to evaluate the effect of different factors (season, gender, location, total lipid, weight and length) on the fatty acid composition and nutritional quality of Cyprinion macrostomus. The results were evaluated through PERMANOVA, principal coordinates (PCO), and cluster analysis for similarity ranges. An analysis of similarity (ANOSIM) was performed on the distance matrix using multiple permutations within a significant fixed effect (p < 0.05). C18:1ω9, EPA and DHA were the most important fatty acids which had an effect on the nutritional quality in all the factor groups. Total lipid amount, season and length factors were the most influential on the fatty acid compositions of C. macrostomus. Summer and Spring were the best the periods for the good nutritional quality of C. macrostomus in terms of AI (Atherogenicity index), TI (Thrombogenicity index) and h/H (Σhypocholesterolemic/Σhypercholesterolemic fatty acid index). In addition, station, gender and weight had no effect on nutritional quality. The study indicated that C. macrostomus is a potential fish meat for human nutrition with high nutritional value in terms of fatty acid composition.

Based on the normal distribution, a new generator of continuous distributions is presented using the monotonic functions and , such that and are the baselines. A study of identifiability of the proposed class is exhibited as well as the series expansions for its cumulative distribution function and probability density function. Additionally, some mathematical properties of the class are discussed, namely, the raw moments, the central moments, the moment generating function, the characteristic function, the derivatives of the log-likelihood function, and a study of the support. A numerical analysis comprising a simulation study and an application to real data is presented. Comparisons between the proposed model and other well-known models evince its potentialities and modeling benefits.
Validation of mathematical models as a tool for prediction of α-amylase production by Coprinus comatus in a low-cost culture medium

Published: May 2023

Studying new microbial sources and evaluating the growth kinetics behavior to predict large-scale production become essential. Besides, research with low-cost culture media has gained interest due to the need to decrease enzyme production costs. The literature concerning the use of macromycetes as a source of amylases, and applying mathematical models to predict their behavior is scarce. In this study, four growth kinetics in different compositions of culture media were carried out: two of them using different concentrations of Low-Grade Flour (LGF), one wheat mill by-product and two synthetic ones. In the kinetics mathematical models were used to evaluate the bioprocesses and their scaling feasibility. Mathematical models, such as modified Logistic, modified Gompertz, Baranyi, and Roberts, and modified Luedeking-Piret, were applied to predict mycelial growth, enzyme production, and substrate consumption. The results showed the model’s capability to predict mycelial growth (biomass) and substrate consumption (starch concentration). On the other hand, the mathematical models efficiently describe only the maximum enzymatic activity (α-amylase), not the process's other parameters, because of the complexity and diversity of biomolecules synthesized by Coprinus comatus. The wheat mill by-product was efficient as an ingredient in the culture media composition. Furthermore, it was concluded that B2 formulation (culture medium with 48.5 g/L of LGF) is the batch with the highest potential for the α-amylase production from C. comatus and the expansion of this process on an industrial scale. This study is important and valid for the scientific community since modeling studies for macromycetes are scarce in the literature.

Introduction: The rise in colorectal cancer (CRC) incidence becomes a global concern. As geographical variations in the CRC incidence suggests the role of area-level determinants, the current study was designed to identify the spatial distribution pattern of CRC at the neighbourhood level in Malaysia.
Method: Newly diagnosed CRC cases between 2010 and 2016 in Malaysia were identified from the National Cancer Registry. Residential addresses were geocoded. Clustering analysis was subsequently performed to examine the spatial dependence between CRC cases. Differences in socio-demographic characteristics of individuals between the clusters were also compared. Identified clusters were categorized into urban and semi-rural areas based on the population background.
Result: Most of the 18 405 individuals included in the study were male (56%), aged between 60 and 69 years (30.3%) and only presented for care at stages 3 or 4 of the disease (71.3%). The states shown to have CRC clusters were Kedah, Penang, Perak, Selangor, Kuala Lumpur, Melaka, Johor, Kelantan, and Sarawak. The spatial autocorrelation detected a significant clustering pattern (Moran’s Index 0.244, p< 0.01, Z score >2.58). CRC clusters in Penang, Selangor, Kuala Lumpur, Melaka, Johor, and Sarawak were in urbanized areas, while those in Kedah, Perak and Kelantan were in semi-rural areas.
Conclusion: The presence of several clusters in urbanized and semi-rural areas implied the role of ecological determinants at the neighbourhood level in Malaysia. Such findings could be used to guide the policymakers in resource allocation and cancer control.

Authors: Fall Abdou Khadre , Diop Pape Sher , Soumare Rougui 
Published: May 2023

L’élevage au Sénégal est une activité qui se mène tant en milieu rural qu’urbain. L’étude réalisée sous forme d’enquêtes auprès de 120 éleveurs de mouton dans la commune de Bambey, a eu pour but d’améliorer sensiblement les connaissances sur l’élevage en milieu urbain sénégalais. Ainsi, l’élevage occupe plus d’hommes (80%) que de femmes (20%). Les éleveurs sont plus de l’ethnie sérère (48%) et wolof (46%) et sont majoritairement instruits (90,83%). La quasi-totalité des éleveurs (88,33%) n’ont jamais reçu de formation en élevage. Ils ont entre 3 à 62 ans d’expérience dans l’activité d’élevage. Les élevages sont plus de type naisseur-engraisseur (49%) qui utilisent plus des ovins de race peul-peul (34%). La taille moyenne des troupeaux est de 7,25 ovins. Les troupeaux sont dominés par les brebis (72,41%). La stabulation permanente est le mode de conduite dominante (80,99%). L’âge moyen de la mise en reproduction des brebis est de 9,19 ±3,11 mois et 12,35 ±3,10 mois chez les mâles. Les saillies sont libres dans 89% des élevages avec une (46%) ou deux mises bas (54%) par an. Les pathologies digestives (76,5% des élevages) et respiratoires (70,5% des élevages) sont les plus rencontrées. L’élevage peut être une source de diversification des revenus.

Englsih title: Diagnosis of urban sheep breeding in the groundnut basin: the case of the commune of Bambey in Senegal
Livestock farming in Senegal is an activity that takes place in both rural and urban areas. The study, which took the form of a survey of 120 sheep breeders in the commune of Bambey, aimed at significantly improving knowledge of livestock breeding in urban Senegal. Thus, more men (80%) than women (20%) are involved in animal husbandry. The breeders are more Serer (48%) and Wolof (46%) ethnic groups and are mostly educated (90.83%). Almost all of the herders (88.33%) have never received any training in animal husbandry. They have between 3 and 62 years of experience in breeding. The farms are more of the breeder-fattener type (49%) and use more Fulani sheep (34%). The average flock size is 7.25 sheep. The flocks are dominated by ewes (72.41%). Permanent housing is the dominant type of management (80.99%). The average age at which the ewes are bred is 9.19 ± 3.11 months and 12.35 ± 3.10 months for the males. Mating was free in 89% of farms with one (46%) or two (54%) births per year. Digestive (76.5% of farms) and respiratory (70.5% of farms) diseases are the most common. Breeding can be a source of income diversification.

Published: May 2023

An analytical multiresidue method for the simultaneous determination of various classes of pesticides in vegetables (tomato, pepper, hot pepper and potato) was developed. Vegetable samples are extracted with acetonitrile.
Final determination was made by gas chromatography with µ-Electron Capture Detection(µ-ECD) for organochloride pesticides. Organophosphorus, pyrithrinoids and other pesticides analysis was carried out by gas chromatography coupled with mass spectrometry in the selected ion monitoring (SIM) mode. The identification of compounds was based on retention time and on comparison of the primary and secondary ions. Recovery studies were performed at various fortification levels of each compound and the recoveries obtained ranged from 70% to 127 % with relative standard deviations lower than 8%. The method showed good linearity over the range studied and the detection and quantification limits for the pesticides studied varied from 0.015 to 0.030 µg.g-1and 0.05 to 0.1 µg.g-1, respectively. The proposed method was used to determine pesticides levels in peppers, hot pepper and tomatoes grown in multichapelle greenhouses at Biskra region and potato grown at Setif region in Algeria.
Evaluation environmental strategies in a semi-arid region : Case of the 50 duplex dwellings of the El-Miniawy brothers in M’sila
Authors: Kersenna S. , Chaouche S. , Bencherif M. 
Published: May 2023

This study aims to evaluate the 50 duplex dwellings of the El Miniawy brothers in M'Sila, using methods of analysis of environmental strategies in order to verify their application by the architects in the construction of these dwellings. A duplex dwelling was selected to undertake an analysis using a mixed methodological approach, combining a qualitative and quantitative method, some of whose strategies were evaluated using the EnergyPlus software and validated by in situ measurements. The results showed that duplex housing has been subject to the application of the strategies in question. We therefore deduce that the construction is efficient and that it ensures the comfort of the user and reduces the negative environmental impact.
This study could constitute an alternative for architects, building designers, planners and decision-makers in order to encourage them to adopt these neo-vernacular environmental strategies of El Miniawy in the development of similar projects in M'sila, and to launch other projects with a contemporary vernacular character.
Hofzwerge: Kleinwüchsige Menschen an deutschsprachigen Fürstenhöfen der Frühen Neuzeit
Authors: Seemann Eva 
Published: May 2023

Wozu brauchten Fürsten »Zwerge« und was taten diese Kleinwüchsigen an einem Hof? Eva Seemann widmet diesem fast vergessenen Hofamt erstmals eine eigene Studie. An den Fürstenhöfen der Frühen Neuzeit waren »Hofzwerge« weit verbreitet. Was aus heutiger Perspektive befremdlich erscheinen mag, war an vielen Höfen bis weit ins 18. Jahrhundert fest etabliert: Sich mit einem oder mehreren »Zwergen« zu umgeben, gehörte für Fürsten und Adlige in ganz Europa zu den Ansprüchen an eine standesgemäße Hofhaltung. Kleinwüchsige Menschen bekleideten als »Kammerzwerge« nicht selten ein eigenes Hofamt, fungierten als Leibdiener, Unterhalter, Spielgefährten, Boten und Vertraute und konnten bisweilen zu einflussreichen Persönlichkeiten werden. Eva Seemann untersucht dieses bisher wenig beachtete Phänomen anhand der deutschen Höfe erstmals in einer eigenen Studie. An der Schnittstelle von Hofgeschichte und Disability History werden so Fragen nach Zugehörigkeit und Ausgrenzung sowie der ambivalente Umgang der frühneuzeitlichen Gesellschaft mit körperlicher Andersheit problematisiert. Auf breiter Quellenbasis und in akteurszentrierter und praxeologischer Perspektive fragt sie nach der Bedeutung dieses Hofamtes für das Funktionieren des frühneuzeitlichen Fürstenhofes, aber auch nach den Lebensbedingungen und Handlungsräumen der oftmals zu Unrecht bemitleideten Kleinwüchsigen am Hof.

Authors: Lopes Giacomin Vinícius , Souza Santos Vaz Diana 
Published: May 2023

Objetivo: Revisar a literatura dos últimos cinco anos, a fim de identificar os possíveis implicações da suplementação de AACRs na cirrose hepática em adultos. Métodos: o levantamento bibliográfico foi realizado em bases de dados indexadas, incluindo em seu escopo estudos observacionais e ensaios clínicos que avaliassem os possíveis impactos da suplementação de AACRs em pacientes adultos cirróticos. Após aplicação dos critérios de exclusão, um total de 8 estudos foram selecionados para compor esta revisão. Resultados: os principais benefícios encontrados indicam melhora significativa no prognóstico, aumento de força muscular e aumento dos níveis de albumina sérica, a administração de AACRs como Late Evening Snacks (LES) também parece estar relacionada à melhores resultados em comparação com a administração durante o dia. Conclusão: apesar dos desfechos positivos, a escassez de estudos nos últimos cinco anos, a heterogeneidade de objetivos e a grande variabilidade de propostas metodológicas dificultam uma conclusão assertiva a respeito da eficácia do suplemento. Ensaios clínicos que correlacionem dosagens e desfechos em amostras maiores são necessários para uma melhor compreensão dos efeitos da suplementação de AACR na população cirrótica.
