The objectives of this document are to assess the impact of climate variability on agricultural production in Colombiaand identify the effectiveness of irrigation districts as an adaptation measure. For the analysis, a panel ofmultidimensional data with random effects was used to estimate the effect on crops reported in 1,101 Colombianmunicipalities, between 2007 and 2017. Two variables were taken as climatic shocks: the sum of the absolute differencesin the monthly precipitation compared to its historical mean and the average of the differences in the monthlytemperature with respect to its historical average. The interaction between irrigation districts and rainfall levels was usedas an adaptability variable. The results indicate that the three-dimensional data panel model presented in this papershowed great applicability despite its low use and the small number of documents that exist on climate effects onagricultural production. The main conclusions are that temperature increases lead to decreases in agricultural productionand that irrigation districts as a measure of adaptation to climate variability do not appear to have a significant impact tocounteract it. We found that practices such as the use of shades could influence the reduction of temperatures locally.Similarly, it is necessary to analyses the impact of measures that mitigate the effects associated with changes intemperature rather than those related to the precipitation regime.

Yellow corn has gained strategic importance for the current government of Mexico due to the enormous amount of thisgrain that is imported, which in turn represents a large flight of capital due to the costs paid abroad to purchase it. Underthese premises, work is being done to obtain a characterization of the different productive units of yellow corn in theirsocioeconomic structure, which allows the generation of an intervention protocol at the three levels of government, in thosemunicipalities where it is possible to plant yellow corn, with native seeds and agroecological fertilizers. The purpose is topromote the development of rural culture, in every sense, and at the same time represents greater income for producers dueto the monetary resource that will no longer go abroad and will remain in the production units. To achieve these objectives,a municipality that has planted yellow corn for several years is taken as a reference point: Ocuituco, Morelos. And anothermunicipality that planted corn in large areas and stopped doing so: Calpulalpan, Tlaxcala.

Improving monochloramine performance with innovative sensor-controlled dosing
Authors: EBERHARDT RYAN , WOODWARD JANET H.
Published: February 2024

Monochloramine (MCA) has become one of the major oxidant chemistries for biological control in the paper industry. Feedback control, such as oxidative-reductive potential (ORP), is often used to provide better control of a dosing scheme. The trademarked Ackumen MCA-i is a chemical-digital solution that uses artificial intelligence with actionable insights to stabilize the wet-end process, providing improved performance and reduction in overall chemical costs. Accurate sensor-controlled dosing can be tied to multiple inputs, such as production rates, grade changes, pH, ORP, chlorine residual, freshwater usage, and more. In this study, a case history will be presented to demonstrate how this technology provided a more consistent MCA molecule throughout the process, resulting in a higher level of efficacy and reduction in chemical costs. Application: Through advanced multiparameter dosing controls, monochloramine feed rates can be adjusted as the paper machine process changes. This leads to the right amount of chemistry being applied at the right time, maximizing efficiency of the biocide program.
Viewing the Characteristics of Chinese Landscape Painting from Guo Xi’s “San Yuan Method”
Authors: Fan Qi
Published: February 2024

The Song and Yuan Dynasties are considered a period when art theory and practice reached a very high level. Among them, painting, as an important category, has great potential. Guo Xi, a painter and theorist of the Song Dynasty, proposed “The San Yuan Method” (means three artistic principles: high, far-reaching and flat), which was compiled into a collection by his son and included in Lin Quan Gao Zhi (the elegance of the bamboo and spring), becoming an important theoretical work in the history of Chinese painting. This article will start from the theoretical foundations of "high", "far-reaching", and "flat" and use specific text analysis and theoretical exposition methods to analyze the painting characteristics of Chinese landscape painting influenced by the " San Yuan Method". The aim is to analyze the creative purpose of landscape painting and appreciate Lin Quan’s heart (Lin Quan's heart is the view put forward by Guoxi, a landscape painter in the Song Dynasty; that is, landscape painters should have an aesthetic mind when observing and painting).

A virtuous debtor: South Korea in the Eurocurrency market, 1969 – 1984
Authors: Kim Seung Woo
Published: February 2024

This article examines the case of South Korea, in which the external private debt management leveraged the symbiosis of the authoritarian regime and the neoliberal policies in a less-developed country. In the pursuit of post-war growthamship, against the meddling of allies with official loans, the military government turned to the Eurocurrency market, an offshore market for major currencies to meet the triple goal of diversifying foreign reserve sources, financing the heavy-chemical industrialization, and underpinning the diplomatic struggle against North Korea. The dependence on the Euro-capital empowered technocrats at the Economic Planning Board to manage the sovereign borrower’s external indebtedness. Against the neo-mercantilist policy, they introduced price stability measures and maintained low debt-service-ratio so as to appease international banks and international financial organizations. Their success enabled the military government to eschew the debt crisis of 1982 and bolstered the legitimacy of the military government. In return, the technocrats resorted to the authoritarian rule to implement market-oriented policies against the labor the neo-mercantilist interests. Drawing on multi-archival sources, this article engages to the burgeoning scholarship on the relations between international banks and authoritarian regimes by analyzing the external debt-driven neoliberal turn in the developing world.

Published: February 2024

Introducción. La violencia de género se evidencia como una problemática normalizada en diferentes contextos sociales debido a esquemas culturales originados a partir de la desigualdad entre hombres y mujeres. Para evaluar el nivel de perjuicio a una persona por la continua exposición a situaciones de violencia, es necesario contar con herramientas psicológicas confiables y válidas; que permitan determinar el tipo de violencia experimentada y el nivel de afectación. Es así, que recurre a la ciencia de la psicometría, que se encarga de la construcción, validación y adaptación de baterías psicológicas que permiten medir comportamientos, en base a procedimientos estadísticos para determinar si una prueba puede ser aplicada en diferentes poblaciones. Objetivo. Evaluar las propiedades psicométricas de las pruebas psicológicas en casos de violencia de género. Metodología. Se utilizó el enfoque mixto, de tipo revisión bibliográfica, documental, nivel descriptivo y de diseño transversal. Para obtener información relevante acerca de las evaluaciones psicológicas en casos de violencia de género se exploraron las bases digitales: Dialnet, Google Académico, Scielo, Scopus, ProQuest, mediante las palabras clave: “violencia de género”, “evaluaciones psicológicas”, “violencia contra la mujer”, “violencia contra el hombre”. Resultados. Los instrumentos empleados con mayor frecuencia son el Dating Violence Questionnaire -R (DVQ-R) y el Cuestionario de violencia en el noviazgo (CUVINO). Conclusiones. Se concluye la efectividad de los instrumentos en base a los criterios de confianza y validez. Además, que las pruebas Cuvino, DVQ-R, Digital Violence Questionnaire (DVQ), Escala de Predicción de Riesgo de Violencia grave contra la pareja (EPV-R) y Escala de valoración de riesgo de violencia contra la mujer (VRVG-M) prueban su eficacia para la evaluación de problemas relacionados con casos de violencia de género, al reconocer aspectos como la victimización, violencia percibida y percepción de riesgo, para luego adoptar medidas de protección a las víctimas sin distinción de género.  Área de estudio general: Psicología Clínica.

KLASTERISASI ANGKATAN KERJA DI INDONESIA BERDASARKAN USIA MENGGUNAKAN METODE ALGORITMA K-MEANS
Authors: Aria Ririn Restu
Published: February 2024

The concept of the population is divided into two groups, namely the working age population and the population not working age. Indonesia, which has 34 provinces, has an unequal distribution of labor force due to the level of economic growth that is still not evenly distributed in several sectors. Labor is the most important and influential element in managing and controlling the economic system. In this study the method used in the grouping of provinces was based on the workforce in 34 provinces using the K-Means algorithm. The purpose of grouping data is done to get a province grouping that has a workforce in Indonesia by grouping / clustering into 3 groups based on age groups using the K-Means algorithm. Based on the calculations, the results of cluster 0 were 6 provinces, cluster 1 as many as 3 provinces and cluster 2 were 25 provinces. The K-Means algorithm can be used to understand the workforce problems and make it easier to describe the characteristics or characteristics of each group. Based on these results, the local government can give more attention to the regions with the smallest workforce such as the Province of Central Sulawesi, East Kalimantan, Jambi so that economic growth in various sectors can be increased so that the welfare of the workforce, especially in terms of work in the field of work can be easily obtained.
The effect of fipronil exposure on the activity of biotransformation enzymes and histology in the liver of grass carp
Authors: Alijani Ardeshir R , Shahidokht S , Mirzaei M , Rastgar S
Published: February 2024

Fipronil (FPN) is an insecticide used in agriculture. This study focused on the biotransformation process and the histopathological effects of FPN in the liver of grass carp. Fish were exposed to environmental concentrations of FPN (3, 6, and 10 ug l-1) for up to 14 d. The alterations in phase I and II biotransformation enzyme activity (ethoxyresorufin-O-deethylase [EROD] and glutathione-S-transferase [GST]), malondialdehyde (MDA) content, and histopathology in the liver were studied on the 1st, 3rd, 7th, and 14th days. Results showed that EROD (dose-dependent) and GST activity (time-dependent) increased. The MDA content increased in a time- and dose-dependent manner. The most common types of hepatological damage were steatosis, vein dilatation, pyknosis, and increased melanomacrophage centers, probably due to oxidative stress originating from biotransformation enzyme activity (R2 = 0.88 for GST and MDA). The degree of tissue change (DTC) at the highest dose indicated moderate damage to the liver (R2 = 0.82 for GST and DTC). Nevertheless, the level of EROD and GST activity and MDA content indicated complex interactions among various phase I and phase II biotransformation enzymes which should be investigated in future studies with more replications.

Published: February 2024

Indonesia's growth cannot be separated from Indonesia's economic growth. The agricultural sector has a massive and significant  impact on Indonesia's economic growth. One of the agricultural products that’s important is rice. Rice is a seasonal crop that is very necessary for human survival. Karawang, one of the districts in West Java Province, which is known as Lumbung Padi City, is the location of the main topic in making this journal. In fact, based on BPS data, the area harvested for paddy fields in Karawang from 2010-2015 was found not to have increased regularly from year to year. This is interesting to discuss because the rice harvest area is expected to increase regularly to support Indonesia's economic growth. Of course, this is because the rice harvest area will affect the amount of rice produced in the rice fields. By ignoring other internal and external factors of rice growth, this journal will only focus on rice harvest area based on rice growth phases (vegetative 1, vegetative 2, and generative) and accumulated harvest area using the Gauss Jordan elimination method. Calculations are carried out to determine the possibility of farmers to predict the maximum amount of rice production and avoid losses in purchasing materials to support rice growth

Este artigo tem como objetivo analisar a influência do Partido Comunista Brasileiro (PCB) na criação e organização de Associações de Moradores de Comunidades do Recife, auxiliando na reafirmação da importância do Movimento de Bairro e sendo capaz de aproximá-los dos governos municipais e estaduais com sua ativa participação e liderança na articulação política e popular chamada Frente do Recife (1955-1964). Entre os anos de 1930 a 1964, a capital pernambucana protagoniza uma série de obras de cunho higienista na cidade, como a expulsão dos mocambos e a reconfiguração das moradias populares consolidadas nas áreas centrais da capital. Diante da metodologia qualitativa aplicada, podemos constatar a influência do PCB, na criação e organização das associações de moradores e como sua liderança na Frente do Recife resultou em um equilíbrio entre as pautas reivindicadas pelos moradores e a assistência da Prefeitura.

Ao percorrer as sendas históricas do Brasil, na década de 1970, podemos observar rastros espessos do projeto político dos militares. Visualizamos que os generais buscavam manter sua posição no comando federal. Para isso, utilizaram recursos como atos institucionais, limitações aos outros Poderes e projetos políticos. Dentre esses projetos, observamos um alinhamento em torno do discurso de integração nacional, onde estados outrora vistos como marginalizados — como o Piauí — foram impulsionados ao crescimento, por meio de governos que valorizavam a construção civil como ferramenta para inserção no “milagre brasileiro” econômico. Constata-se então um discurso híbrido, cuja imprensa figura como a principal porta voz dos feitos da ditadura. Este artigo é fruto de uma pesquisa empírica a partir de documentos oficiais e de matérias publicadas nos jornais O Dia, O Estado e Estado do Piauí, que são analisados a partir da interlocução com os estudos de Robert Darnton, Anne-Marie Smith, Beatriz Kushnir, Carlos Fico e Cláudia Fontineles.

Linear to multi-linear algebra and systems using tensors
Authors: Pandey Divyanshu , Venugopal Adithya , Leib Harry
Published: February 2024

In the past few decades, multi-linear algebra also known as tensor algebra has been adapted and employed as a tool for various engineering applications. Recent developments in tensor algebra have indicated that several well-known concepts from linear algebra can be extended to a multi-linear setting with the help of a special form of tensor contracted product, known as the Einstein product. Thus, the tensor contracted product and its properties can be harnessed to define the notions of multi-linear system theory where the input, output signals, and the system are inherently multi-domain or multi-modal. This study provides an overview of tensor algebra tools which can be seen as an extension of linear algebra, at the same time highlighting the differences and advantages that the multi-linear setting brings forth. In particular, the notions of tensor inversion, tensor singular value, and tensor eigenvalue decomposition using the Einstein product are explained. In addition, this study also introduces the notion of contracted convolution for both discrete and continuous multi-linear system tensors. Tensor network representation of various tensor operations is also presented. In addition, application of tensor tools in developing transceiver schemes for multi-domain communication systems, with an example of MIMO CDMA system, is presented. This study provides a foundation for professionals whose research involves multi-domain or multi-modal signals and systems.

Weaning is a stressful period in a piglet’s life, when many morphological and functional changes occur in the gastrointestinal tract. Examples are an alteration of the barrier function and an increase in production of cytokines, suggesting the immune system of the GIT is activated after weaning. The goal of this study was to evaluate the effect of a commercially available feed additive based on short and medium chain fatty acids on supporting intestinal health and reduce inflammation in the intestine of post-weaning piglets. Seventy piglets were divided over 2 treatments, a control diet and a blend of short and medium chain fatty acids, including butyrate. On day 0, 15, 30 and 45 after weaning blood samples and intestinal tissue samples were collected from sacrificed piglets. Blood and tissue samples were analysed for cytokine gene expression, and tissue samples from jejunum and ileum were analysed on morphology and gene expression of tight junctions. Results show that the use of a blend of short and medium chain fatty acids, including butyrates, improved intestinal morphology, measured by villous length and v/c ratio, reduced expression of tight junction proteins and influenced cytokine production in the intestine, implicating that the use of organic acids as feed additives potentially can reduce damage caused by weaning to the intestinal barrier and due to the higher absorption capacity of the villi potentially improve nutrient absorption.

Background: The functional movement screen (FMS) has been used to identify deficiencies in neuromuscular capabilities and balance among athletes. However, its effectiveness in detecting movement anomalies within the population afflicted by knee osteoarthritis (KOA), particularly through the application of a family-oriented objective assessment technique, remains unexplored. The objective of this study is to investigate the sensitivity of the FMS and daily activities in identifying kinematic abnormalities in KOA people employing a markerless motion capture system.

Methods: A total of 45 persons, presenting various Kellgren–Lawrence grades of KOA, along with 15 healthy controls, completed five tasks of the FMS (deep squat, hurdle step, and in-line lunge) and daily activities (walking and sit-to-stand), which were recorded using the markerless motion capture system. The kinematic waveforms and discrete parameters were subjected to comparative analysis.

Results: Notably, the FMS exhibited greater sensitivity compared to daily activities, with knee flexion, trunk sagittal, and trunk frontal angles during in-line lunge emerging as the most responsive indicators.

Conclusion: The knee flexion, trunk sagittal, and trunk frontal angles during in-line lunge assessed via the markerless motion capture technique hold promise as potential indicators for the objective assessment of KOA.

Gram-negative bacterium Acinetobacter sp. Tol 5 exhibits high adhesiveness to various surfaces of general materials, from hydrophobic plastics to hydrophilic glass and metals, via AtaA, an Acinetobacter trimeric autotransporter adhesin Although the adhesion of Tol 5 is nonspecific, Tol 5 cells may have prefer materials for adhesion. Here, we examined the adhesion of Tol 5 and other bacteria expressing different TAAs to various materials, including antiadhesive surfaces. The results highlighted the stickiness of Tol 5 through the action of AtaA, which enabled Tol 5 cells to adhere even to antiadhesive materials, including polytetrafluoroethylene with a low surface free energy, a hydrophilic polymer brush with steric hindrance, and mica with an ultrasmooth surface. Single-cell force spectroscopy as an atomic force microscopy technique revealed the strong cell adhesion force of Tol 5 to these antiadhesive materials. Nevertheless, Tol 5 cells showed a weak adhesion force toward a zwitterionic 2-methacryloyloxyethyl-phosphorylcholine (MPC) polymer-coated surface. Dynamic flow chamber experiments revealed that Tol 5 cells, once attached to the MPC polymer-coated surface, were exfoliated by weak shear stress. The underlying adhesive mechanism was presumed to involve exchangeable, weakly bound water molecules. Our results will contribute to the understanding and control of cell adhesion of Tol 5 for immobilized bioprocess applications and other TAA-expressing pathogenic bacteria of medical importance.
