Nicotinic acid hydrazide and 2,4-dihydoxylbenzaldehyde were condensed at 20 °C to form an acylhydrazone (H3L1) with ONO coordination pattern. The structure of the acylhydrazone was elucidated by using CHN analyzer, ESI mass spectrometry, IR, 1H NMR, 13C NMR and 2D NMR such as COSY and HSQC. Thereafter, five novel metal complexes [Mn(II), Fe(II), Pt(II) Zn(II) and Pd(II)] of the hydrazone ligand were synthesized and their structural characterization were achieved by several physicochemical methods namely: elemental analysis, electronic spectra, infrared, EPR, molar conductivity and powder X-ray diffraction studies. An octahedral geometry was suggested for both Pd(II) and Zn(II) complexes while both Mn(II) and Fe(II) complexes conformed with tetrahedral pyramidal. However, Pt(II) complex agreed with tetrahedral geometry. In vitro antitubercular activity study of the ligand and the metal complexes were evaluated against Mycobacterium tuberculosis, H37Rv, by using micro-diluted method. The results obtained revealed that (PtL1) (MIC = 0.56 mg/mL), (ZnL1) (MIC = 0.61 mg/mL), (MnL1) (MIC = 0.71 mg/mL) and (FeL1) (MIC = 0.82 mg/mL), exhibited a significant activity when compared with first line drugs such as isoniazid (INH) (MIC = 0.9 mg/mL). H3L1 exhibited lesser antitubercular activity with MIC value of 1.02 mg/mL. However, the metal complexes displayed higher cytotoxicity but were found to be non-significant different (P > 0.05) to isoniazid drug.

Present study was focused on purified terephthalic acid (PTA) industry wastewater treatment located at Port Qasim, Karachi. PTA wastewater containing high COD (100000 to 150000 mg/L) was treated with coagulate ferrous ion and then was oxidized independently with aqueous hydrogen peroxide using different doses at 45 °C for 1h. The resulting wastewater was passed through RO plant equipped with high porosity bio-ceramic membrane. It was observed that coagulation and oxidation processes have potential to reduce 87.9% COD but complete reduction up to 99.8% was achieved after passing the effluents from high RO plant equipped with high porosity ceramic membrane.

В статье отмечается, что при осуществлении новой государственной политики в области воспитания подрастающего поколения целесообразно учитывать исторический опыт организации воспитательной деятельности в учебных заведениях системы Государственных трудовых резервов СССР в 1940–1950-е годы. В работе выявлены и структурированы фундаментальные принципы организации идейного, военно-патриотического и физического воспитания молодежи: наличие стержневой воспитательной идеи; непрерывность воспитательных усилий на протяжении всего срока обучения; комплексный характер воспитательной деятельности; выделение ограниченного круга приоритетных задач; активное вовлечение в воспитательную работу в системе Государственных трудовых резервов комсомола. Проведенный анализ позволил сделать вывод о том, что некоторые принципы и отдельные содержательные элементы модели воспитания учащихся системы Государственных трудовых резервов можно использовать сегодня при разработке современной концепции воспитания российской молодежи.
The article notes that when implementing a new state policy in the field of education of the younger
generation, it is advisable to take into account the historical experience of organizing educational
activities in educational institutions of the State Labour Reserves of the USSR in the 1940s and 1950s. The paper identifies and structures the fundamental principles of the organization of ideological, military-patriotic and physical education of young people: the presence of a core educational idea; the continuity of educational efforts throughout the entire period of training; the complex nature of educational activities; allocation of a limited range of priority tasks; active involvement in educational work in the system of State Labour Reserves of the Komsomol. The analysis made it possible to conclude that some principles and some content elements of the model of education of students in the system of State Labour Reserves can be used today in the development of a modern concept of education of Russian youth.

Authors: Felippeto João , Caliari Vinícius , Brighenti Emílio , Nesi Cristiano Nunes 
Published: June 2021

A expansão da vitivinicultura nacional para além das áreas tradicionais é uma realidade cada vez mais notória. Entretanto, a diversidade climática entre as diferentes regiões produtoras expõe as plantas a condições ambientais distintas e capazes de influenciar o seu desempenho. Neste contexto, estudos sobre o comportamento das variedades frente ao seu ambiente de cultivo são importantes subsídios técnicos na implementação de novos empreendimentos. O objetivo foi avaliar a fenologia, as necessidades térmicas e a maturação de oito variedades viníferas entre 2013 a 2020 nas condições de São Joaquim-SC. As condições térmicas disponíveis na região foram expressas em graus-dia (GD) de forma correlativa com as avaliações fenológicas. As colheitas foram submetidas às análises de acidez total, pH e SST. O ciclo vegetativo médio das variedades foi de 200 dias, sendo a ‘Rebo’ a variedade com ciclo mais longo e a ‘Manzoni Bianco a com ciclo mais curto’. As variedades estudadas produziram frutos com parâmetros de maturação adequados para a elaboração de vinhos finos, com destaque para a ‘Rebo’ dentre as tintas e ‘Manzoni Bianco’ dentre as brancas.
Hermenêutica, narrativa, ação e cosmologia:
Authors: Lima Ribeiro Saulo Duarte 
Published: June 2021

A tarefa da hermenêutica é reconstruir o sentido do texto e a referência, e sabe-se que a definição do significado de um texto mudou muito, tendo como alguns expoentes da hermenêutica Hans-Georg Gadamer, Paul Ricoeur e E. D. Hirsch, sendo Gadamer quem concebe uma miscelânea de operações no que se refere à escrita. A correspondência da imaginação ao argumento do tempo é operada no campo da atribuição narrativa. Em seu Do Texto à Acção, Ricoeur relaciona hermenêutica, ação humana e texto, efetivando fenomenologia como hermenêutica e apresentando a relevância da linguagem e criatividade no processo hermenêutico. Em O si-mesmo como o outro, Ricoeur traz uma análise acerca da tarefa inicial de reorientação do que analisa, libertando-o da prerrogativa da auto-reflexão. Em Tempo e narrativa, Ricoeur em seu capítulo Tempo da alma e tempo do mundo analisa a investigação cosmológica a partir das perspectivas principalmente para Aristóteles e Agostinho sobre o tempo, observando que a consciência humana tem potencial para transitar sobre mais de um sentido, de forma que o mesmo se dispõe a buscar uma terceira resolução à aporia da temporalidade apresentada nos dois pensadores. O presente artigo busca trazer uma breve análise da hermenêutica e cosmologia a partir da perspectiva de Paul Ricoeur.
O DESPERDÍCIO DA EXPERIÊNCIA E DA FONTE DE OBSERVAÇÃO ÚLTIMA DO PROFETA SOFONIAS EM CONTEXTO COM AS ALIANÇAS DIVÍNAS E OS ELEMENTOS REDENTIVOS DE UM REINO VINDOURO
Authors: ARAÚJO IDÍLIO OLIVEIRA 
Published: June 2021

Na Teologia bíblica é comum a análise dos profetas de forma abrangente procurando fazer a exegese e interpretação do sentido de cada livro e relacioná-lo com as Boas Novas. Argumenta-se que a palavra do Profeta é a mensagem de Deus para seu povo. A partir da análise dos pactos divinos, teologicamente, desenvolvo o estudo do livro do Profeta Sofonias buscando responder as seguintes questões: Quais as alianças divinas estão sendo citadas e quais os elementos da quebra das alianças e quais as ofertas de redenção no livro do Profeta? Ainda, analiso quais os juízos pelo pecado e se existe profecia messiânica pelo novo mediador. O presente artigo faz uma análise estratificado das alianças divinas permeada pela limitação do livro. Ilustra-se o tema descrevendo-se a visão de Palmer Roberttson e o seu escólio sobre as Alianças divinas. Por derradeiro conclui-se, com enfoque nas alianças divinas, que Sofonias focaliza a necessidade de vivermos em retidão diante de Deus e que de todos os profetas, Sofonias provavelmente foi o que descreveu o juízo com mais intensidade, tendo também enaltecido a possibilidade da restauração para aqueles que se arrependessem e voltassem à retidão.

Published: June 2021

Resum: En el present article oferim una edició crítica del Llibre de cetreria, un breu tractat de falconeria escrit en català i conservat en manuscrit únic pertanyent a una col·lecció privada. També n’estudiem l’estructura i el contingut, a més de les relacions amb altres obres de falconeria, especialment les escrites a la Corona d’Aragó. Oferim una hipòtesi sobre la identificació del seu autor i l’època de la composició del tractat. Com que es tracta de l’obra escrita en català que major nombre d’ocells de caça esmenta, a la present edició ens ha semblant oportú de fer una exposició detallada de les aus emprades pels caçadors, com també tota la terminologia que la llengua catalana va desenvolupar per a referir-s’hi.Paraules clau: falconeria, caça, noblesa, Corona d’Aragó, ocells de presa. Abstract: In this article we offer a critical edition of Llibre de cetreria [Book of falconry], a brief treatise of falconry written in Catalan. It is kept as a sole manuscript belonging to a private collection. We study its structure and content, as well as its relations with other falconry archive documents, namely written in the Crown of Aragon. We formulate a hypothesis about the authorship and the age when the treatise was written. This is the Catalan treatise naming the greatest number of birds of prey. Hence, in this edition we offer a thorough exposition of the birds used by hunters, and the related terminology that was developed in Catalan.Key words: falconry, hunting, nobility, Crown of Aragon, birds of prey.

Abstract: This work focuses in the edition of a medieval falconry text written in Catalan. This is an interesting text because of its length and the quality of its language, with a rich, varied, and specialized vocabulary. It joins two different treatises, copied into a larger 15th-century miscellaneous manuscript, in which other treatises are also collected, such as one on women’s cosmetics, another on cooking, etc. Although the sources of the Llibre dels ocells de caça, o Flors de les receptes medicinals per a ocells de caça seem very abundant, we annotate the edition with the source allowing a more direct comparison because of the proximity between the Latin and Catalan text; namely, the De falconibus by St. Albert the Great, of which there is a partial version in folios 122v to 138v of the manuscript.

Riuen les meduses: cos i desig a la poesia de Carmelina Sánchez-Cutillas i Maria-Mercè Marçal
Authors: Díaz Vicedo Noèlia 
Published: June 2021

Resum: Aquest article estudia per primera vegada les continuïtats entre la poesia de Maria-Mercè Marçal (1952-1998) i Carmelina Sánchez-Cutillas (1921-2009). Específicament, se centra en l’obra poètica publicada en vida de les dues escriptores i que es troba recollida dins Llengua abolida (1973-1988) (1989) de Marçal i Obra poètica (1997) de Sánchez-Cutillas. Encara que les condicions sociohistòriques són diferents entre les dues poetes, en aquest article intentaré demostrar que l’escriptura en totes dues beu directament de la seua experiència vital donada per la posició del seu cos de dona i la interacció intel·lectual amb el llenguatge i els significats culturals heretats. Des d’aquests qüestionaments, en aquest article oferiré una aproximació al contínuum de la problemàtica de la subjectivitat femenina, nucli de la seua obra, des de la interacció entre cos i llenguatge, paràmetres centrals que ocupen els estudis de la diferència sexual, en particular en la teoria denominada écriture féminine desenvolupada per les filòsofes Hélène Cixous i Luce Irigaray. Paraules clau: cos, desig, Carmelina Sánchez-Cutillas, Maria-Mercè Marçal, écriture féminine Abstract: This article explores for the first time the continuities between the poetry of Maria-Mercè Marçal (1952-1998) and Carmelina Sánchez-Cutillas (1921-2009). Particularly, it focuses upon the poetic works published during their lifetime, collected in the volumes Abolished Language (1973-1988) (1989) by Marçal and Poetic Works (1997) by Sánchez-Cutillas. Despite their different socio-historical conditions, in this article I analyse how their vital particular experiences as female subjects become the cornerstone of their writing and how the position of their body interacts with language, consequently challenging their inherited socio-cultural significations. In order to discuss my points, I draw upon the parameters developed by the theoretical framework of écriture féminine developed by philosophers Hélène Cixous and Luce Irigaray.Keywords: body, desire, Carmelina Sánchez-Cutillas, Maria-Mercè Marçal, écriture féminine
Promoting effect of rapamycin on osteogenic differentiation of maxillary sinus membrane stem cells
Authors: Lin Yanjun , Zhang Min , Zhou Lin , Chen Xuxi , Chen Jiang , Wu Dong 
Published: June 2021

Background
Stem cells located in the maxillary sinus membrane can differentiate into osteocytes. Our study aimed to evaluate the effect of rapamycin (RAPA) on the osteogenic differentiation of maxillary sinus membrane stem cells (MSMSCs).

Methods
Colony-forming unit assay, immunophenotype identification assay, and multi-differentiation assay confirmed characteristics of MSMSCs obtained from SD rats. Transmission electron microscopy (TEM) and flow cytometry (FCM) identified the initial autophagic level of MSMSCs induced by RAPA. Real-time quantitative PCR (qPCR) evaluated subsequent autophagic levels and osteogenic differentiation. Alkaline phosphatase (ALP) activity assay and alizarin red staining (ARS) evaluated subsequent osteogenic differentiation. We performed a histological examination to clarify in vivo osteogenesis with ectopic bone mass from BALB/c nude mice.

Results
MSMSCs possessed an active proliferation and multi-differentiation capacity, showing a phenotype of mesenchymal stem cells. The autophagic level increased with increasing RAPA (0, 10, 100, 1,000 nM) and decreased over time. ALP activity and calcium nodules forming in four RAPA-treated groups on three-time points (7, 14, 21 d) showed significant differences. Col1a1, Runx2, and Spp1 expressed most in 100 nM RAPA group on 7 and 14 d. Osteogenesis-related genes except for Ibsp expression between four groups tended to be consistent on 21 d. 100 nM and 10 nM RAPA-treated groups showed more bone formation in vivo.

Conclusion
RAPA can promote osteogenic differentiation of MSMSCs, indicating a possible relationship between osteogenic differentiation and autophagy.
An Assessment of the Physico-Chemical Parameters of Mangrove Soils that Support Nypa fruticans and Other Mangrove Species Establishment in the Cameroon Estuary

Invasion of Nypa palm into mangroves is a problem in the Cameroon Estuary. Soil variability is one of the dominant features that support Nypa palm establishment. The objective was to characterize the soil under the different mangrove stands; Purely Nypa palm stands (A), mixed stands i.e Nypa palm and other mangrove species (B) and other mangrove species i.e Nypa palm free (C), determine the principal soil characteristic critical for Nypa spread. 9 plots of 20 x 20 m were laid in each of the sites. 27 soil samples were collected in the North, West, South East and Center at a depth of 30 cm in these three sites using a soil auger. The results in the three sites indicated that; soils were acidic (3.87- 4.39), pH values did not significantly differ (alpha >0.05), organic matter was low in A (12.32%) and B (16.35%).Soil Organic Carbon ranged from (4.52 to 7.06%). High percentage of organic carbon content was recorded in C (7.06%). Low percentage of organic carbon was found in A (4.52%). Total nitrogen varied from 1.04 g/kg, 1.70g/kg, 1.80 g/kg in sites C, A and B. In all the mangrove stands, the values of Exchangeable Ca content were below 4.0 cmolkg-1. Soil texture in the three sites were; sandy, clay and silt. Power test showed no significant different in soil types between the three sites (p>0.05). According to the component matrix the factor is positively loaded by soil EC, moisture content, organic matter, organic carbon, N, C/N, CEC, Ca, Mg, K, Na, Clay, Silt, and negatively loaded by the percent sand. This study therefore, suggests that since soil plays key role in Nypa palm establishment, there should be constant monitoring of soil quality to forestall drastic changes that will jeopardize the survival of the mangroves. Nypa palm seedlings should also be physically removed from mangrove forest to prevent colonization. In addition, more mangrove seeds should be planted in deforested mangrove areas to close the window of opportunity for the palms.
