Competitiveness of Indian Agricultural Exports: A Constant Market Share Analysis
Authors: Kumar K. Nirmal Ravi
Published: May 2022

The 1991 Indian reforms aimed at economic liberalization, as a part of its economic structural adjustment, and transformed the nation’s economy into a more global market-based and service-oriented system, which revolutionized its agricultural trade facet. The new regime paved the way for self-reliant Indian agriculture to expand its roots into the spheres of global competitiveness and export orientation. India enjoys a competitive advantage in the international market and considering the growth in India’s exports of major agricultural commodities. This study employed the Constant Market Share model to analyze the export performance of its various facets such as diversification, instability, elasticity, competitiveness, etc. The findings revealed that India’s growth performance of major agricultural commodities’ exports both in terms of quantity and value was found satisfactory (except wheat and cashew nuts, shelled (quantity)) during 1991-2020. During the recent past decade, i.e., 2011-2020, World Demand Effect (WDE) is the main source of India’s agricultural export performance (due to the general rise/fall in world demand given a constant market share of India, unlike Market Distribution Effect (MDE), Commodity Composition Effect (CCE) and the Residual Competitiveness Effect (RCE) due to high inconsistency arising out of changes in the external environment). Both MDE and RCE with respect to commodity-wise exports and CCE and RCE with respect to country-wise exports are found negative for the majority of commodities and countries (markets) respectively. Consistently negative CCE for exports of agricultural products, total and across major export destinations were found more disheartening and this should deserve special attention. So, it is imperative to boost the export competitiveness of agricultural commodities from India and the future prospects of exports depend on how much the latest surge in COVID-19 infections in India affects its agricultural production and global demand conditions.
Derecho Internacional de los Derechos Humanos. Fuente de obligaciones para el sistema normativo guatemalteco
Authors: Vicente Gudiel Juan Arnulfo , Véliz Arriaga Leslie Argentina
Published: May 2022

A partir de la recepción que el Estado de Guatemala ha hecho a nivel constitucional del Derecho Internacional de los Derechos Humanos se ha venido generando, en forma paulatina, una transformación muy significativa en las fuentes sistema normativo guatemalteco.

El presente artículo aborda tal variación, afirmando que, esta metamorfosis resulta de la sumatoria de sistema jurídicos de protección de derechos humanos (sistema universal y sistema interamericano) a los que pertenece el Estado de Guatemala, los cuales, al ingresar al sistema jurídico nacional forman una nueva estructura de protección a los derechos humanos, tomando, como, al bloque de constitucionalidad como una herramienta interpretativa idónea para integrar y armonizar la normativa nacional e internacional. Asimismo, se analiza las obligaciones y deberes internacionales que surgen de la recepción constitucional de los tratados y convenios de derechos humanos, así como, la importancia de un efectivo control de convencionalidad para el cumplimiento de las responsabilidades adquiridas soberanamente por el Estado
Límites al poder constituyente: los artículos pétreos de la Constitución de la República de Guatemala y el rol de la soberanía popular
Authors: Girón Lemus Herbert Rocael
Published: May 2022

La soberanía es el poder supremo dentro de todo estado y, conforme al principio democrático, en el estado moderno se ha ubicado dicho poder en el pueblo como su detentador. Es un poder supremo que determina su propio orden jurídico y político que lo rige. A pesar de ello, existen constituciones que contienen cláusulas pétreas, entendidas estas como prohibiciones impuestas por el poder constituyente para reformar ciertas disposiciones constitucionales, aspecto que parece contradictorio con la supremacía del soberano y el principio democrático del estado. Es oportuno por ello cuestionar la legitimidad de las cláusulas pétreas constitucionales, corroborar si la Constitución de la República de Guatemala las contiene y finalmente, analizar el rol que la soberanía popular tiene respecto a tales disposiciones.

Selivanovaite, ideally NaFe3+Ti4(Si2O7)2O4(H2O)4, is a murmanite-group (seidozerite supergroup) TS-block mineral from the Lovozero massif, Kola Peninsula, Russia. The crystal structure of selivanovaite was refined in space group C, a 10.524(6), b 13.815(6), c 12.213(14) Å, α 99.74(6), β 107.45(8), γ 90.15(10)°, V 1666.8(26) Å3, R1 = 21.40%. The previously given chemical analysis has been modified to better fit the crystal structure: Nb2O5 8.51, ZrO2 2.94, TiO2 31.96, SiO2 30.62, Al2O3 0.05, Fe2O3 5.08, FeO 3.23, MnO 3.36, CaO 2.14, MgO 0.75, Na2O 2.47, H2O 8.88, sum 99.99 wt.%; H2O was determined from structure-refinement results: H2O = 3.34 pfu, OH = 1.05 pfu. The empirical formula calculated on 22 O apfu is: (Na0.63Ca0.30Mn0.36)Σ1.29(Fe3+0.50Fe2+0.35)Σ0.85(Ti3.14Nb0.50Zr0.19Mg0.15Mn0.01Al0.01)Σ4.00Si3.99O22.00H7.73, Z = 4. The crystal structure of selivanovaite [basic structure type B1(MG)] is an array of TS blocks (Titanium Silicate) connected via hydrogen bonds. The TS block consists of HOH sheets (H = heteropolyhedral, O = octahedral) parallel to (001). In the O sheet, the Ti-dominant MO(1,2) sites, Na-dominant MO(3) site, and □-dominant MO(4) sites give ideally Na□Ti2pfu. In the H sheet, the Ti-dominant MH(1,2) sites, Fe3+-dominant AP(1) site, and vacant AP(2) sites give ideally Fe3+□Ti2pfu. The MH and AP(1) polyhedra and Si2O7 groups constitute the H sheet. The ideal structural formula of selivanovaite of the form AP2MH2MO4(Si2O7)2(XOM,A)4(XPM,A)4 is Fe3+□Ti2Na□Ti2(Si2O7)2O4(H2O)4. Selivanovaite is a Fe3+-bearing and OH-poor analogue of vigrishinite, ideally Zn□Ti2Na□Ti2(Si2O7)2O2O(OH)(H2O)4. Vigrishinite and selivanovaite are related by the following substitution: O(OH)–vig + H(Zn2+)vig ↔ O(O2–)sel + H(Fe3+)sel. Selivanovaite is a Fe3+-bearing and Na-poor analogue of murmanite, ideally Na2Ti2Na2Ti2(Si2O7)2O4(H2O)4. Murmanite and selivanovaite are related by the following substitution: O(Na+)mur + H(Na+2)mur ↔ O(□)sel + H(Fe3+)sel + H(□)sel. The doubling of the t1 and t2 translations of selivanovaite compared to those of murmanite is due to the ordering of Fe3+ and □ in the H sheet and Na and □ in the O sheet of selivanovaite.

El deterioro de las construcciones hechas con ignimbrita en el centro histórico de Arequipa, es un problema causado por el intemperismo, emisión de contaminantes industriales y biológicos, afectando su preservación. Se evaluó aplicar a la ignimbrita, polisiloxano funcionalizado con nanopartículas de plata (PXS-AgNPs), como recubrimiento para disminuir su porosidad, evitar su degradación y darle un efecto protector a su superficie.Las nanopartículas de plata (AgNPs) se sintetizaron, por reducción de nitrato de plata (AgNO3) con borohidruro de sodio (NaBH4), el polisiloxano se sintetizó por hidrólisis del clorosilano en agua y éter dietílico; que fue funcionalizado con AgNPs, mezclando soluciones acuosas de PXS y de AgNPs, obteniéndose un gel de color amarillo lechoso. Se aplicó PXSAgNPs a la superficie de la ignimbrita y se realizaron pruebas de adsorción con solución de azul de metileno 1ppm, que se contrastó con ignimbrita sin PXS-AgNPs. Encontrando en la ignimbrita con PXS-AgNPs un porcentaje de recubrimiento del 85,98 % y en la ignimbritasin PXS-AgNPs un porcentaje de recubrimiento del 61,04%, existiendo una diferencia de 36,65% de adsorción, demostrándose que con el PXS-AgNPs se mejora la protección de la ignimbrita.

Se caracterizó la ignimbrita recubierta con PXS-AgNPs, por SEM EDX observando una estructura con cristalizaciones y una tenue capa cubriéndolas del PXS-AgNPs; por EDX se observa una señal por la presencia de plata; por FT/IR bandas a 981 cm-1 y 1243 cm-1 del siloxano; en el análisis por TGA una inflexión a 362.65ºC del punto de fusión del PXS, a 630,22°C por la descomposición del PXS, lo que indica que tiene resistencia térmica; en el análisis por ICP-masa se encontró 0.48 mg/K de Ag por su presencia en el PXS-AgNPs.En cuanto a la actividad antimicrobial del PXS-AgNPs, se encontró la disminución de mesófilos totales de 3950 UFC/g en la ignimbrita sin PXS-AgNPs a 125 UFC/g en la ignimbrita con PXS-AgNPs; los hongos disminuyeron de 4 UFC/g en la ignimbrita sin PXSAgNPs a 1 UFC/g en la ignimbrita con PXS-AgNPs, lo que demuestra la efectividad del PXS-AgNPs ante la actividad microbiana.Todas las pruebas realizadas demuestran la efectividad del PXS-AgNPs como recubrimiento, tanto en el aspecto fisicoquímico como en la actividad microbiana, mejorando la protección de la ignimbrita.

New combinations in Crystallopollen Steetz (Asteraceae: Vernonieae), the correct name for the illegitimate Polydora Fenzl ex H.Rob.
Authors: Manning John , Govaerts Rafael
Published: May 2022

Polydora Fenzl (1844) is recognised to be a nomen nudum that was only validly published by Robinson (1999). The inclusion by Robinson (1999) of the earlier validly published Crystallopollen Steetz ([in Peters] 1864) as a synonym however, rendered Polydora Fenzl ex H.Rob. (1999) superfluous and so illegitimate. Crystallopollen Steetz ([in Peters] 1864) is therefore the correct name for the genus as circumscribed by Robinson (1999) and later authors. Only one of the namescurrently accepted in Polydora has a combination in Crystallopollen and the necessary additional combinations are provided here for C. bainesii (Oliv. & Hiern) J.C.Manning, C. chloropappum (Baker) J.C.Manning, C. jelfiae (S.Moore) J.C.Manning, C. mbalense (G.V.Pope) J.C.Manning, C. rhodesiana (S.Moore) J.C.Manning, C. serratuloides (DC.)

INVESTIGATION OF SAFETY CONDITIONS IN THE TRANSPORT OF DANGEROUS GOODS BY RAILWAY
Authors: Slavinskaitė Neringa , Batarlienė Nijolė
Published: May 2022

Safe transport of dangerous goods by railway is an important challenge for both national and international freight transport. The transport of dangerous goods is one of the most demanding transportation technologies. The aim of this article is to assess the conditions for the transport of dangerous goods by railway and to define the main factors, which affect the transport of such goods by railway. Scientific literature was analysed, statistics were provided, and a qualitative survey was conducted. The factors of 3 groupas that have the greatest impact on the safe transport of dangerous goods by railway were studied and identified. The obtained results were processed using the Kendall’s rank correlation method, and the consistency of the expert opinions was clarified using the fit coefficient. Using the medium-distance transformation weights (Average Rank Transformation Into Weight – ARTIW) method, the main normalized subjective weighting factors that most influence the conditions of transport of dangerous goods for safe transport have been identified. The results of the study revealed that the main factors of Group I that have the greatest impact on the accident of dangerous goods by railway, are: complete preparation of the train, driver’s confidence in the safety systems of the locomotive and improper loading of cargo. The most important technical-technological factors of Group II, which have the greatest impact on the accident occurring in the transportation of dangerous goods by railway, are: technical condition of the locomotive, tightness of railway tanks (wagons) and marking of wagons carrying dangerous goods. Key organizational factors for Group III to consider before dangerous goods are transported by railway are: risks related to freight forwarding, identification of chemical properties of freight and driver qualification. The key factors in these three groups can be used to develop models to make the transport of dangerous goods by railway safer and more efficient.
Galactic Kites
Authors: Loeb Abraham
Published: May 2022

I show that interstellar films of material thinner than a micron, drift away from the Galactic plane as a result of stellar radiation pressure. Such films, whether produced naturally by dust coagulation in proto-planetary disks or artificially by technological civilizations, would accumulate over the age of the Milky Way and hover above the Galactic disk at a scale-height set gravitationally by the dark matter halo. Limits on scattered starlight imply that this population carries a fraction below 2 × 10−3 of the interstellar medium mass.

Notacanthella jinwu Li & Jacobus, sp. nov. is described based on egg, nymph, and winged stages from Dali Bai Autonomous Prefecture, Yunnan Province, China. The nymph of the new species is closely related to N. commodema (Allen, 1971), whose nymphs share a similar tuberculation of head, pronotum, and mesonotum. However, the nymph of our new species can be distinguished based on the structures of male sternum IX and abdominal tergal tubercles. In addition, the new species is distributed in subtropical high-altitude areas. The description of the male imago of the new species is the first certain one for the genus Notacanthella. Data associated with our new species allow for expanded discussion and diagnosis of Notacanthella and closely related genera. An identification key for nymphs of these groups is provided.

Quelques nobles sortent du lot, comme Gaston de Béarn et Centulle de Bigorre. Un troisième personnage leur est souvent associé, le comte Rotrou du Perche. Il a pourtant été peu étudié et, lorsque c’est le cas, seulement du point de vue « français » ou du point de vue « espagnol ». L’étude de la carrière aragonaise de Rotrou manque d’une vision d’ensemble. Les deux facettes de son parcours sont très peu mises en relation alors qu’elles sont indissociables pour comprendre le personnage et ses actes. C’est l’objectif de cet article de replacer le comte du Perche dans les flux vers la péninsule que draine la Reconquista au début du xii e  siècle, d’estimer son importance dans le royaume d’Alphonse le Batailleur et de comprendre comment il a en parallèle continué à diriger son territoire du nord de la Loire.
Paul-Émile de la Fruglaye : un agent royaliste breton en Normandie (1795-1799)
Authors: Le Gouaréguer Mikaël
Published: May 2022

Paul-Émile de La Fruglaye (1766-1849) est un homme a priori banal et sans relief, resté dans l’ombre des grands capitaines martyrs de la Contre-Révolution. Bien qu’il ne soit pas exactement le genre d’anonyme qui aurait intéressé Alain Corbin et les tenants de la micro-histoire, l’histoire de La Fruglaye permet une relecture de la chouannerie normande du point de vue d’un simple royaliste dont la postérité a tout juste retenu le nom. En effet, bien qu’il n’ait pas attiré l’attention des érudits et des historiens, son rôle d’agent de renseignement et de liaison a paru indispensable aux protagonistes de ce combat, notamment Louis de Frotté. Par ailleurs, il constitue une bonne illustration de la relation compliquée entre le gouvernement britannique et les émigrés français. Du point de vue de l’histoire militaire enfin, La Fruglaye est un des ancêtres des officiers insérés dans les états-majors internationaux. À son époque, il expérimente déjà la complexité des subordinations multiples.
Les catholiques de Seine-Inférieure face à la condamnation de l’Action française par le pape en 1926
Authors: Limare Antoine
Published: May 2022

En 1926, l’Action française est condamnée par le pape Pie XI, ce qui provoque un tournant décisif pour la ligue nationaliste et pour le comportement politique des catholiques français. En Seine-Inférieure, les répercussions de cette décision sont remarquables en raison de la proximité de l’archevêque de Rouen, André du Bois de La Villerabel, avec la ligue monarchiste. Cette dernière connaît durant les années 1920 son apogée politique et culturel dans les milieux conservateurs et catholiques. Dès lors, l’intervention pontificale bouleverse les relations entre le clergé, ses fidèles et les ligueurs maurrassiens dans un département encore marqué par un catholicisme politique. La condamnation pontificale tarde à s’imposer et les réactions contradictoires qu’elle suscite ont des conséquences à long terme sur l’audience de l’Action française en Seine-Inférieure.

Authors: Hou Rui , Xu Yongqing , Fan Jinhua , Zhu Yuanguo
Published: May 2022

We investigate the asymptotic behaviors of American maximum options with dividend-paying assets near maturity. Using the exercise conditions of American options, we obtain the asymptotic forms of the two boundaries with respect to time-to-maturity. Furthermore, we derive the matched asymptotic expansion for the rescaled value function of American maximum option. The all results are provided with detailed computations and derivations. Numerical examples show that the asymptotic value function and exercise boundaries can provide an efficient alternative for the true ones, respectively.
« Dansa es us dictatz gracios » : la dansa occitane du xiie au xive siècle
Authors: Chaillou-Amadieu Christelle , Saviotti Federico
Published: May 2022

L’article constitue la première étape d’une étude interdisciplinaire d’ensemble sur la dansa de langue d’oc, le virelai de langue d’oïl et les autres genres lyriques romans qui leur sont apparentés. Suivant une approche à la fois philologique et musicologique, l’étude se concentre sur l’histoire de la dansa troubadouresque de ses débuts à 1400 environ, avec une discussion sur la définition de sa forme fondée sur les témoignages des sources médiévales, la délimitation de son corpus (entre Occitanie et Catalogne) et, enfin, sur ses origines possibles. À cet égard, une attention particulière est portée à la prétendue dérivation de la dansa d’une production d’ascendance populaire (ou popularisant) telle que celle des compositions à refrain et/ou ayant un schéma de type « zadjalesque ». L’analyse détaillée des traits distinctifs de la dansa et la comparaison avec le répertoire sacré des hymnes et des conductus permet en revanche de conclure qu’elle trouve son origine dans la canso courtoise des troubadours, sous l’influence de la production liturgique et paraliturgique des responsoria.

Uma parcela significativa da população mais velha dos países de média e baixa renda vivencia adversidades para o envelhecimento cognitivo. Neste contexto, é útil o estudo de medidas, como o Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE), que utilizam respondente substituto para avaliação de idosos acometidos por transtornos neurocognitivos. O presente estudo verificou se prejuízos funcionais e cognitivos e se queixas subjetivas de prejuízos da saúde física e cognitiva seriam preditores do escore do IQCODE a partir de acompanhamento de 9 anos com idosos brasileiros comunitários. A amostra foi composta por 118 idosos, e seus informantes substitutos, participantes da linha de base do Estudo FIBRA-JF. Utilizou-se a regressão logística multinomial, tendo o IQCODE como variável desfecho e como variáveis independentes, as características sociodemográficas; o estado de saúde; o desempenho no Mini-exame do Estado Mental (MEEM); as alterações para realizar atividades básicas (ABVD), instrumentais (AIVD) e avançadas (AAVD) de vida diária; a satisfação com a vida; a metamemória e a Escala de Depressão Geriátrica (EDG). Alterações no MEEM, nas AIVD e na GDS há 9 anos, e os prejuízos observados após este período para as ABVD, AIVD e AAVD, foram identificados como indicadores explicativos das perdas funcionais e cognitiva relatadas pelo informante. Estes achados reforçaram a utilidade do IQCODE como ferramenta de avaliação cognitiva de idosos.

O processo de ensino-aprendizagem é afetado por múltiplos desafios que exigem que os professores dediquem grande parte do tempo às aulas, lidando com situações interpessoais complexas. O objetivo desse estudo foi avaliar os efeitos do Treinamento de Habilidades Sociais Educativas para Professores em situações de difícil relacionamento interpessoal em sala de aula, considerando as dimensões probabilidade e desconforto. A dimensão probabilidade refere-se à possibilidade de os participantes utilizarem estratégias habilidosas para lidar com essas situações e a dimensão desconforto refere-se à dificuldade emocional de agir de forma socialmente competente. Participaram do estudo doze professores do Ensino Fundamental, de 25 a 35 anos (M = 29,5; DP = 3,0), que lecionavam em instituições privadas. Foram realizadas dez reuniões com duração de até noventa minutos. Os participantes responderam às medidas em dois momentos (pré-intervenção e pós-intervenção) quanto ao grau de desconforto emocional e à probabilidade de ocorrência de habilidades sociais educativas. A análise dos dados foi realizada pelo Método JT e os resultados indicaram que todos os participantes apresentaram melhoras clínicas positivas em ambas às dimensões, com exceção de um único participante.

Authors: Oliveira Lima Patrícia , Araujo de Morais Normanda
Published: May 2022

The objective of the current article is to obtain a better understanding about the theme of digital abuse among intimate partners through the analysis of the scientific literature. For this purpose, we carried out an integrative literature review in four databases: SciELO, Virtual Health Library (VHL), Pepsic and Pubmed in the period from 2015 to 2020. After considering the inclusion and exclusion criteria, 33 articles were identified and analyzed. Most of the articles were written in North American English and published in 2018. They were cross-sectional and quantitative studies and made use of standardized instruments. The reviewed studies emphasize the prevalence, consequences, risk factors, the very definition of the phenomenon and the association of digital abuse with beliefs about love and offline violence. According to our findings, investigating the experience of digital abuse is an important task since it is a common phenomenon, especially among young people, and there are many health-affecting consequences. In addition, these findings add to the growing body of evidence on the negative effects of cyber dating abuse, and it is believed that risk determination is useful for clinical and educational interventions.

STEM education promotes scientific inquiry and engineering design, including mathematics, incorporating appropriate technologies. Portable technologies motivate active learning of students and enable accessing to learn resources, facilitating cross-disciplinary designing tasks. This chapter initially presents theoretical approaches of STEM education, mobile learning, and inquiry-based learning, and then it describes an inquiry-based short-term intervention that took advantage of portable digital devices in a STEM class. The aim of the intervention was to study its affection on students' motivation about physics. Results indicate that students who participated in the activity had higher motivation scores than their classmates who attended lessons with conventional teaching methods. The findings also show that the students involved in a guided inquiry-based process became more profoundly engaged in STEM than their classmates who followed a structured inquiry process. Other factors, such as grade point average (GPA) and gender, did not seem to affect student motivation.

Published: May 2022

Science, technology, engineering, and mathematics (STEM) education is integrated into education programs in many countries because it benefits the national economy and raises qualified manpower. During STEM-based activities, students increase their problem-solving and research skills by using technology and engineering knowledge together with science and mathematics knowledge. When the studies in the literature are examined, although it is seen that STEM education has positive contributions, it is encountered that the current resources for teachers are limited. The lack of up-to-date resources for teachers causes them to be insufficient in their field knowledge. Apart from this, teachers need to follow current technologies to be able to correctly apply the technology and engineering steps in STEM education and to have a high level of technological literacy. This study will provide information about the integration of educational robots in the researches to be done in the field of STEM education and give an idea to the studies to be done on the subject.

MOOCs have emerged as an important form of Open and Distance Learning. The success of a MOOC platform depends on the support services and the motivational environment that it provides. This paper presents a comprehensive picture of the literature on the motivations that drive learners to enroll in MOOCs, published between the years 2011 to 2020. In this study, an attempt has been made to examine various research papers, for identifying key motivational factors related to the learners, platform, course and facilitating conditions for enrollment in MOOCs. Using the systematic literature review strategy, the papers are classified based on the technologies adopted to facilitate the discovery of directions displayed by the available literature and determining the current gaps, so that they may be addressed in the future. It was further found that various important hidden factors are still untouched or has limited literature on them, which makes MOOCs system successful.

Authors: Nasrudin Muhamad Fikry , Mas’ud Zainal Alim , Khotib Mohammad
Published: May 2022

Tobacco seed of the Voor-oogst variety has a high oil content and is harvested as waste from tobacco plantations, but it has not been utilised optimally. The purpose of this research was to obtain the best quality oil from tobacco seed using ultrasonic-assisted extraction (UAE). Oil was extracted from tobacco seeds using ultrasonic waves with various extraction times (30, 60, and 90 minutes) and n-hexane solvent volume (100, 125, and 150 mL). The quality of the oil was determined based on the moisture content, acid number, and saponification number. An analysis using ANOVA was performed to identify the best quality of oil statistically. The highest yield from the extraction process was 23.38% oil from 90 minutes of extraction treatment and 150 mL of solvent volume. The extraction treatment using n-hexane solvent volumes of 125 and 150 mL had a similar yield based on ANOVA. The main fatty acid of tobacco oil was linoleic acid (54.10%), oleic acid (8.18%), palmitic acid (7.92%), and stearic acid (2.10%). Based on the high linoleic content, the Voor-oogst variety of tobacco seed oil has the potential to be applied in the fields of cosmetics and food supply.
Synthesis of N-Phenylpyrazoline Derivative from 4-Chlorobenzaldehyde and 4-Chloroacetophenone and its Activity as an Antimalarial Agent

Published: May 2022

This study was aimed to synthesize N-phenylpyrazoline derivative and evaluate its antimalarial activity. The pyrazoline was synthesized from chalcone derivative through a cyclo- condensation reaction. Moreover, chalcone derivative was prepared from 4-chlorobenzaldehyde and 4-chloroacetophenone through Claisen-Schmidt condensation. The structure elucidation of the products was performed by FTIR, GC-MS, 1H- and 13C-NMR spectrometers. The antimalarial assay was conducted by inhibition of heme polymerization. The chalcone was obtained as a white solid in 83% yield, while N-phenylpyrazoline derivative was obtained as brown solid in 70% yield. The IC50 values of chalcone and N-phenylpyrazoline derivatives as well as a positive control (chloroquine diphosphate) were 98.66, 20.83, and 3.54 mg/mL, respectively. The results showed that both chalcone and N-phenylpyrazoline derivatives had lower antimalarial activity than the positive control. Molecular docking studies were also performed to explain the mode of action of chalcone and N-phenyl pyrazoline as antimalarial agent.
