Authors: ASTUTI KARTIKA FIDI , SURINI SILVIA , BAHTIAR ANTON
Published: January 2023

Objective: Andrographolide is the primary active constituent that was isolated from Andrographis paniculata and has been adopted to treat rheumatoid arthritis. Several studies revealed that it has poor oral bioavailability and skin penetration, which can be solved through the transdermal delivery of ethosomes. Therefore, this study aims to determine the pharmacokinetic profiles, relative bioavailability, and efficacy of andrographolide in the form of transdermal ethosomal gel in rheumatoid arthritis (RA) animal models. Methods: Andrographolide was processed into ethosomes using the thin layer hydration-sonication technique. Its physical properties were then characterized, including particle size, polydispersity index, zeta potential, and entrapment efficiency, before it was incorporated into a gel dosage form. An in vivo study was also carried out on male Sprague Dawley rats. Subsequently, two gels, namely ethosomal and non-ethosomal, as well as an oral solution were prepared for the pharmacokinetic study. For the anti-rheumatic activity, thirty-six male rats were divided into three controls as well as three treatment groups, which were treated with 25, 50, and 100 mg/kg of andrographolide. During the induction and post-treatment phases, clinical manifestations of arthritis were thoroughly monitored. Results: The andrographolide ethosomes were successfully prepared with particle sizes of 76.35±0.74 nm and entrapment efficiency of 97.87±0.23%. Based on the pharmacokinetic studies, the Cmax obtained for ethosomal and non-ethosomal gel, as well as oral suspension, were 53.07±4.73, 27.34±1.48, and 11.72±0.74 μg/ml with AUC0-∞ of 152.10±16.53, 77.15±12.28, and 23.20±3.46 μg. h/ml, respectively. Furthermore, the relative bioavailability recorded for the preparations was 655.60%. Anti-rheumatic activity investigations revealed that the 50 and 100 mg/kg ethosomal gels reduced oedema volume closely with 0.135 mg methotrexate subcutaneously. Conclusion: The ethosomal gel enhanced Cmax, AUC0-∞, and the relative bioavailability of andrographolide. Furthermore, it reduced oedema volume, ankle joint diameter, and arthritic scores in RA rats.

TEOREMA STOLPER-SAMUELSON, BRECHA SALARIAL Y LIBERALIZACIÓN COMERCIAL: ANÁLISIS COMPARATIVO DE MÉXICO Y ESTADOS UNIDOS, 1990-2020
Authors: Cerezo García Verónica , Landa Díaz Heri Oscar
Published: January 2023

En la teoría del comercio internacional estándar se asume que el libre intercambio comercial puede conducir a la convergencia de los precios de los bienes y a la igualación de los precios de los factores de la producción. La mayor integración comercial entre México y Estados Unidos ha propiciado un incremento del volumen de exportaciones y una mayor inversión extranjera directa en México. El objetivo principal de este artículo es identificar si el proceso de liberalización comercial ha generado un efecto Stolper-Samuelson en ambos países. Mediante un modelo econométrico con datos panel del periodo 1990-2020, encontramos evidencia de que en México la brecha salarial ha disminuido para los trabajadores con menos educación y de que en Estados Unidos ha sucedido un fenómeno similar para los trabajadores con más educación.
 
THE STOLPER-SAMUELSON THEOREM, WAGE GAP AND TRADE LIBERALIZATION: A COMPARATIVE ANALYSIS OF MÉXICO AND THE UNITED STATES, 1990-2020
ABSTRACT
The standard theory of international trade maintains that free trade leads to good and factor of production prices equalization. Following this conventional wisdom, North American countries —in particular Mexico— engaged in a major trade liberalization which led significant increases of both exports and foreign direct investment in Mexico. The aim of this article is to assess whether economic liberalization has induced a Stolper-Samuelson effect in Mexico and the United States. An econometric model is built using panel data for the period 1990-2020 to enquire whether the wage gap has been affected by trade liberalization. It is shown empirically that such gap has been reduced for low-skilled Mexican workers, whereas a similar phenomenon is confirmed for higher-skilled American workers.

Published: January 2023

News media is one of the main sources of information for many people around the world on climate change. It does not only increase awareness among the public but also have the potential to sensitize people toward climate change impacts. Till date, few studies focus on media coverage of climate change in the low-income countries such as Pakistan which is among the top ten countries impacted by global warming. This study used Latent Dirichlet Allocation (LDA) topic modeling and analyzed 7,655 climate change-related news articles published between 2010 and 2021 in three Pakistani English newspapers. Our results suggest that climate change coverage in Pakistan has substantially increased over the years, however, the focus has generally been on "climate politics'', "climate governance and policy'', and "climate change and society''. Evolution of different themes and its potential implications on people are discussed.

Published: January 2023

A lo largo de la crisis sanitaria provocada por la epidemia de COVID-19, la investigación internacional ha documentado diversas afectaciones en la salud mental de la población general. Sin embargo, pocos estudios se han enfocado en estudiar la situación de los niños y los adolescente. El objetivo del presente estudio fue evaluar el nivel de ansiedad y depresión de una muestra de niños de la Ciudad de México, durante la pandemia de COVID-19 en diciembre de 2020. Adicionalmente, se analizó el impacto de las clases en línea y el confinamiento provocado por la emergencia sanitaria. Participaron un total de 52 niños en un rango de edad de 6 a 12 años, que cursaban la educación primaria (50% fueron mujeres). Se contó con la autorización de los padres para la participación de los niños. La recolección de los datos se realizó por medio de un formulario en línea, que incluía cuestionarios psicométricos estandarizados para evaluar el nivel de ansiedad y depresión de los niños; así como una serie de preguntas donde los padres informaban de la situación escolar de sus hijos y datos sociodemográficos. Los resultados señalaron que 33% de los niños se ubicaban en un nivel clínico significativo para depresión. Al mismo tiempo, 31% de los niños mostraban niveles clinicamente significativos de ansiedad. Los niños de escuelas privadas y que cumplían con su horario completo de clases fueron los que mostraron una mayor afectación al respecto. Se destaca la necesidad de generar programas de intervención para atender a esta población.

Published: January 2023

The purpose of the article is to: write about the regulation of criminal law enforcement and the legal consequences for the police who commit violence against protesters. With this aim, in this article, we will discuss: The regulation of criminal law enforcement and legal consequences for the Police who commit violence against Protesters. With this discussion, the research method used is normative juridical research. This article concludes that: 1) In providing security during rallies, law enforcement officers, in this case the police, still carry out many acts of violence to deal with anarchic protesters. 2) The police as law enforcement officers in dealing with anarchic protesters should prioritize preventive measures and other actions that are permitted and allowed by law to be carried out. 3) Violent actions in dealing with anarchic protesters must be avoided, however, because they can provoke anarchy and even greater chaos. In addition, to Article 18 of Law Number 2 of 2002 concerning the Police, amendments also need to be made because it is still unclear and firm on the use of the article, as well as regarding the limits on actions that are allowed to be carried out based on that article.

Climate change poses a severe threat to many taxa, with increased mean
temperatures and frequency of extreme weather events predicted. Insects
respond to non-optimal temperatures using behaviours or local
microclimates to thermoregulate (thermal buffering ability), or through
physiological tolerance. We studied the thermal buffering ability and
thermal tolerance of a community of 54 butterfly species in Panama.
Thermal buffering ability and tolerance were influenced by family, size,
and colour, with Pieridae, large, and dark butterflies having the
strongest thermal buffering ability, and with Hesperiidae, small, and
dark butterflies tolerating the highest temperatures. We identified an
interaction between thermal buffering ability and physiological
tolerance, where species with stronger thermal buffering abilities had
lower thermal tolerance, and vice versa. This interaction implies that
most species will be vulnerable to climate change to an extent,
considering that species appear to adapt to one strategy at the expense
of the other.
The effect of metal-titania interaction on photodegradation in SBA-15-supported metal-titania photocatalysts
Authors: Göl Sevgi , Akbay Elif
Published: January 2023

Several transition metals (Fe, Cu, Ni, Cr, and Co) were inserted into the Ti-SBA-15 using two-step synthesis methods. XRD, SEM-EDX, N2 adsorption-desorption isotherms, XRF, and UV-DRS analysis were used for characterizations. The results confirmed preserving an ordered mesoporous structure, well-dispersed Ti-metal and enhanced light absorption compared with Ti-SBA-15. The photocatalytic performances were evaluated in the degradation of methylene blue under UV light. The results show that the Co-Ti-SBA-15 exhibited the highest photocatalytic activity among the prepared photocatalysts for the degradation of methylene blue. The significant activity increase might be attributed to the increased reactant adsorption by the mesoporous structure of SBA-15, the good distribution of TiO2 in the pores of SBA-15, and the increased electron transfer mobility due to metal doping. In addition to efficiency, Co-Ti-SBA-15 is a suitable catalyst for dye degradation, exhibiting good stability in methylene blue degradation over five photocatalytic runs without any deviation of the structure.

A number of factors can significantly affect the accuracy of height determination when applying the GNSS leveling method. In general, it is possible to distinguish those related to the process of GNSS observations and their post-processing, and those related to the selection of the geoid/quasi-geoid height model. This work focuses on aspects of GNSS leveling accuracy when choosing global geoid models. In particular, to better ensure accuracy, it is important to understand the significance of the heights tidal system selection of global geoid models. The purpose of the work is to analyze the influence of different tide systems of global geoid models on the accuracy of height determination by the GNSS leveling method. This paper considers the heights of global geoid models EGM08, EIGEN-6C4, GECO, and XGM2019e_2159 of high degree and order calculated in the tide systems of “tide-free”, “mean-tide”, “zero-tide”. The analysis of the actual accuracy of the geoid heights was carried out on the basis of the standard and root mean square deviations of the heights differences of global geoid models in the corresponding tidal systems in relation to the GNSS leveling data. GNSS leveling data were obtained at 14 high-precision geometric leveling points of accuracy class 1-2, covering the central part of the Lviv region. Similarly, the accuracy of the geoid models was analyzed taking into account the differences of gravity anomalies concerning the high-resolution anomalies of the WGM2012 model. Data presenting differences of height and gravitational anomalies allowed us to correct the height of the models according to the weighted average principle. In addition, corresponding statistics were calculated for them. The conducted analysis shows that for the EGM08 model, the system of “mean-tide” is optimal with an accuracy assessment at the level of σ=2-3 cm and m=4 cm. For the EIGEN-6C4 model, it is best to use the “zero-tide” system which will ensure accuracy up to 4-5 cm. The accuracy of the EGM08 and EIGEN-6C4 models is confirmed by the statistical characteristics analysis results of the gravity anomaly differences. The GECO and XGM2019e_2159 models give ambiguous results within 3-9 cm by both parameters and in all tidal systems. Only after correction of the heights, their accuracy is 2-5 cm. Considering the optimal tidal system, the heights of the EGM08 and EIGEN-6C4 models can provide an accuracy of 1-3 cm after the correction by weighting coefficients.

Pest infestation is a major problem in corn cultivation because it causes a decrease in crop productivity or even crop failure. This study aimed to evaluate the level of crop damage caused by Helicoverpa armigera and Ostrinia furnacalis in three tropical altitude variations. Ten hybrid corns from cross-breeding strains and three commercial hybrid corn varieties were evaluated at three locations with different altitudes, classified as lowland (30 masl), midland (600 masl), and highland (1000 masl). The evaluation was carried out on the level of crop damage and plant resistance. The results showed that the highest percentage of H. armigera attack on hybrid corn was 75% at Caps 17B x Caps 23 (moderately susceptible) at the lowland and the lowest was 8% at Caps 2 x Caps 17A (resistant). The percentage of H. armigera attack was 100% at Caps 15 x Caps 22 (very susceptible) and the lowest was the evaluation of Caps 5 x Caps 17B was 58% (susceptible) at the midland. Meanwhile, the highest attack percentage was 92% on the Caps 17A x Caps 17B, Caps 17A x Caps 22, and Caps 5 x Caps 22 hybrids (very susceptible), while the lowest was 67% on the Caps 3 x Caps 17B and Secada hybrids (moderately susceptible) at the highland. O. furnacalis attack showed that all hybrid corns were classified as resistant except for Caps 5 x Caps 22 and Paragon was moderately resistant with a percentage attack of 25% at lowland. At the midland, Caps 5 x Caps 17B hybrid corn was classified as very susceptible with an attack of 92%, while Caps 15 x Caps 22 was classified as resistant with an attack percentage of 8%. At an altitude of 1000 masl, Caps 17A x Caps 17B, Caps 3 x Caps 17A, and Caps 5 x Caps 17B were moderately resistant with an attack percentage of 33% and other hybrids were resistant with an attack percentage of 8%.

Published: January 2023

Baduy women have a special and honorable position because they are directly related to the concept of Ambu and Nyi Pohaci (the Goddess of Rice) as the goddess of the source of Baduy life. With this identification, the food security of the Baduy family and community is determined by the role of women. The need for agricultural land/fields continues to be urgent, slowly among them in 2010-2012 the Baduy people were able to buy land outside of customary land covering an area of 900 hectares spread over 12 sub-districts designated as agricultural land expansion. Land expansion is needed to meet food availability as well as family economic income which has an impact on increasing welfare. The land is purchased from years of savings from financial management and women's creative industries. This study aims to determine the method/model of the role of Baduy women in food security for families and communities through qualitative research with activity theory and religious communication. The result is that Baduy women continue to use their traditional positions and roles by utilizing customary knowledge and skills which continue to be developed with concessions to the interpretation of customary law and are carried out according to social and economic motives to return to the big motive, namely the religious motive to buy land and carry out functions. worship as a farmer and the concept of Sunda Wiwitan belief.

O presente estudo discute uma perspectiva teórica possível, para o Ensino de Matemática por Atividades Experimentais (EMAE), na Educação Matemática. Assim, apresenta-se alguns apontamentos iniciais, visando a configuração de pressupostos de base, para estudos recentes, desenvolvidos ou em desenvolvimento, envolvendo o ensino por atividades experimentais, pautados na Teoria da Atividade (TA). Propõem-se uma configuração teórica, estabelecida com base na 2ª geração de TA e posteriores aperfeiçoamentos. Assim, defende-se um mecanismo possível de sustentação teórica, envolvendo interações, em atividades experimentais para o ensino de matemática, relacionados aos movimentos que preconizam diálogos e ações em um Sistema de Atividade Expansivas. Nesse sentido, a experimentação no ensino, se torna um vetor de composição e discussão para o campo educacional, a serem desenvolvidas, na busca em entender e compreender o sentido dos conceitos, linguagem e estruturas matemáticas, associadas a diferentes situações e problemas propostos em uma atividade de ensino. Em síntese, apresentamos uma tese inicial, a ser confirmada ou não, em estudos futuros e em curso: a tese de que há uma unidade de experimentação (consciente e/ou inconsciente) presente em praticamente todas as abordagens e tendências em educação matemática, que levem em consideração, atributos e ações pedagógicas intencionais - para o ensino – e possíveis de ocorrerem, independente da configuração ou natureza das atividades propostas, em um dado espaço ou cenário de aprendizagem matemática.

Published: January 2023

Apresenta resultados de uma pesquisa etnográfica que analisou a condição juvenil e os projetos de vida de jovens estudantes do ensino médio, moradores de um município rural da microrregião de Governador Valadares, Minas Gerais. O objetivo é discutir alguns aspectos dos processos de escolarização desses jovens. A análise fundamenta-se em estudos contemporâneos da sociologia da juventude e da educação. Constatou-se que ter acesso ao ensino médio foi um grande feito para essa geração, com histórico familiar de baixa escolaridade; no entanto, o sonho de ir além esbarra em frustrações como condições precárias de estudos; falta de sentido do currículo, desarticulado da realidade em que os alunos vivem; e falta de identidade desse nível de ensino.

Authors: Rogowski Andrzej , Zagożdżon Beata
Published: January 2023

Modern science is based on the study of economic phenomena and tries to quantify them in a measurable way. Econometric models are used for this purpose. The object of this research was to develop econometric models that show the strength of the influence of various factors on the implementation of public-private partnership (PPP) projects in the area of transport infrastructure in France, GB, Germany, the Netherlands and Belgium. The models express the dependence of the value and number of PPP contracts on the value of measurable PPP success factors. Projects with a value of at least EUR40 million were included. A linear model and seven models transformable to linear were used. Four groups of factors were considered as explanatory variables. Fourteen indicators were obtained. Principal components determined based on covariance and correlation matrices were also used. The best models for the number of PPP contracts are linear and hyperbolic I models. For the value of contracts - linear and hyperbolic I and logarithmic models. The best models were indicated taking into account the type of explanatory variables and regardless of the type of explanatory variables.  Nine criteria were used to assess the quality of the models. Factors having a significant impact on the value and number of PPP models were identified from the best models. Factors having no significant influence were also indicated.

Published: January 2023

Against the social background of the gradual transformation of the social pension mode and the arrival of the ageing age, the tool design of fitness walkers for the elderly was studied. In this paper, the physiological and psychological status of the elderly with mild or moderate stroke or unable to exercise due to the decline of physical function was analysed. In addition, the corresponding elderly fitness walker product market research was studied. Aiming at these problems, this paper proposes a set of elderly fitness walker frames based on the ergonomic semiotic approach of the product architecture design (SAPAD) model. First, the development and structure of artificial engineering is introduced in detail. Then the framework of walking aid for the elderly based on the SAPAD model is proposed, and the SAPAS model and walking aid for the elderly are introduced, respectively, along with the framework of simulation design and application. The experimental results show that the framework of elderly fitness walker based on the ergonomic SAPAD model can be implemented. It can be applied to the elderly’s fitness assistance. A fitness walker can be suitable for the elderly who want to continue to exercise; it also hopes to care for the elderly who need to exercise from the perspective of the product.

Seven date seeds cultivars, Deglet Nour, Degla Baïdha, Fakht, Ghars, Hamraya, Tafezouin and Takermost were provided from Algerian Sahara. Some of these Algerian date seeds were studied for the first time (Fakht, Hamraya and Takermost). The biochemical characterization of these date seeds were studied, including fatty acids and minerals profiles. The results showed that date seeds are a good source of carbohydrates and crude cellulose, with averages of 66.63 and 13.20%, respectively. They are also a good source of proteins, with the cultivar Deglet Nour seeds as the richest one (9.27 ± 0.03%). The main fatty acid for all date seeds oils is oleic acid except for Deglet Nour in which lauric acid is the main one. However, the studied date seed oils could be classified as oleic-lauric oil. Potassium was the highest mineral in all date seeds cultivars, with values ranging from 2700 to 2900 mg/Kg, followed by sodium and iron. These results indicate that date seeds have good nutritional value with different compositions among cultivars. It could be concluded that date seeds could be considered as a good opportunity for their technological and industrial valorization.

Authors: Daszkiewicz Tomasz
Published: January 2023

The quality of the longissimus lumborum muscle has been compared in male moose, red deer, fallow der and roe deer from wild populations. The results of this study indicated that Cervid meat had favorable chemical composition and high sensory quality but its properties were affected by the species of the animal. The highest quality was characterized roe deer meat. It was found that her meat had the best water-holding capacity and was most tender, and intramuscular fat had highest nutritional value. However, due to the high diversity and variation of factors affecting game meat quality, further research is needed to confirm the observed interspecific differences between members of the family Cervidae.

The aim of the study was to modify and adapt to other matrices the fast and simple method for determining total lipid content expressed as fatty acid methyl esters (FAME) by performing the in situ transesterification. The primary method was published as a technical report for the FAME analysis in algae dry mass. Our modifications included the use of less toxic solvents, the use of an internal triglyceride standard and FAME determination by the gas chromatography technique coupled with the mass spectrometry technique in the Single Ion Monitoring mode (SIM). The modified method was validated for 37 fatty acids (saturated, monounsaturated and polyunsaturated) containing from four to twenty-four carbons in the carbon chain (C4-C24), and was adapted to five food matrices: three solids (yeast, yeast flakes, biscuits), and two liquids (milk thistle (Silybum marianum (L.) Gaertner) oil and olive oil). Additionally, 14 samples of spices and superfood samples, rich in unsaturated oils were analyzed. The validation parameters: linearity, precision, recovery, limits of detections and quantifications, were assessed and additionally Certified Reference Material of olive oil was analyzed.

In most developing nations, there has been an increase in the consumption of wheat-based products, particularly biscuits, due to recent lifestyle changes and rapid urbanization. Due to this, there has been a sudden rise in research into creating flour from locally grown cereals or legumes to satisfy consumer demand. As a result, the potential for making biscuits with sorghum-soy composite flour was investigated. The flour blends and the corresponding biscuit products’ functional and physicochemical characteristics were established. The samples of biscuits’ organoleptic characteristics were also identified. The functional properties of the composite flours decreased while their proximate composition increased, according to the results. As the amount of sorghum-soy flour inclusions increased, the physical characteristics of the biscuit samples decreased. The moisture contents, protein contents, crude fats, ash, crude fibers, and carbohydrates were all within the ranges of 3.11 to 3.80%, 14.80 to 17.66%, 5.07 to 5.51%, 3.65 to 4.94%, 2.66 to 3.64%, and 66.11 to 70.71%, respectively. The sorghum-soy biscuits fared well compared to the wheat-based biscuits and were deemed acceptable. As a result, eating these biscuits will increase people’s nutrient intake, particularly that of children, as well as the utilization of sorghum and soybean in tropical nations.

Published: January 2023

Biosurfactants have wide applications in several industries. However, high production costs and safety concerns have limited their comprehensive use. Twenty-five strains of lactic acid bacteria, isolated from fermenting maize slurry, were screened for biosurfactant production using the emulsification activity (E24) assay. The selected bacterium was identified molecularly using the 16S rRNA gene sequencing as Lactobacillus plantarum OG8. The effect of some cultural factors on biosurfactant production from the bacterium, using pineapple peel as a low-cost substrate, was investigated. The optimum yield of biosurfactant occurred at a 48 h incubation period, using glucose and peptone as carbon and nitrogen sources, respectively. The biosurfactant was characterized to possess mostly carbohydrates, followed by protein and lipid contents. Optima pH 10.0 and temperature 60 °C were the best for the biosurfactant activity. The biosurfactant exhibited antimicrobial activity against bacterial pathogens Staphylococcus aureus, Bacillus subtilis, Escherichia coli, and Klebsiella pneumoniae, at a concentration of 5.0 mg/mL. The use of pineapple peel as a low-cost substrate for biosurfactant production from Lactobacillus plantarum OG8 will serve for cost-effective production. The biosurfactantt produced exhibited promising properties such as thermostability and antimicrobial activity against food spoilage and pathogenes that could make it suitable for food processing and preservation.
