Abstract. Triyogo A, Budiadi, Widyastuti SM, Subrata SA, Budi SS. 2020. Abundance of ants (Hymenoptera: Formicidae) and the functional groups in two different habitats. Biodiversitas 21: 2079-2087. Land development often affects the quantity and diversity of ants (Hymenoptera: Formicidae). The aim of this study, therefore, was to determine and compare the ant species abundance and the functional groups between two different habitats, representing land development, including pioneer and agroforestry. This research involved a survey of the ants at the Forest Research Education (FRE) of Wanagama I Yogyakarta, and data were accumulated over a period of five months (April, May, June, July, and August). In addition, pit-fall trap and direct collection methods were used, involving the placement of 54 pit-fall traps at two habitats, and the ant specimens were retrieved after a two day period. The results show the total individual abundance of 2,310 and 2,067, on agroforestry and pioneer, respectively. Furthermore, the species richness and diversity index was higher in agroforestry (7; 2.01), compared with pioneer (6; 1.49), where the three dominant species include, Anoplolepis gracilipes, Solenopsis sp., Odontoponera denticulata; and Anoplolepis gracilipes, Odontoponera denticulata, Camponotus sp., respectively. Conversely, the highest amount of invasive ants (Solenopsis sp.) was observed in agroforestry, which negatively impacted on the presence of native species (Odontoponera denticulata). In addition, PCA analysis showed the development of three ant groups on each habitat, hence agroforestry made more real differences in the aspect of species abundance, and none in terms of richness. Therefore, notable differences were observed in the ant communities between both habitats, and agroforestry was indicated as a disturbed area, based on the increment in tramp and invasive ants, alongside low abundance of native and functional groups.

Abstract. Sibero MT, Siswanto AP, Pribadi R, Sabdono A, Radjasa OK, Trianto A, Frederick EH, Wijaya AP, Haryanti D, Triningsih DW, Hayuningrat SJ, Igarashi Y. 2020. The effect of drying treatment to metabolite profile and cytotoxic potential of Rhizophora apiculata leaves. Biodiversitas 21: 2180-2187. Coastal communities in Indonesia have utilized Rhizophora spp. leaves as a traditional medicine for many years. The previous studies have succeeded in extracting bioactive compounds from this mangrove after drying treatment, but there is a possibility of the compound decomposition or breakdown. This study aimed to determine the effect of drying treatment on the metabolite profile of R. apiculata leaves which were taken from mangrove forests in Rembang, Central Java. The effect of pre-drying treatment was examined by comparing the metabolites profiles of fresh, oven-dried, and sun-dried leaves crude extracts. Extraction was carried out using maceration method with agitation (110 r.p.m.) for 24 hours in methanol. The metabolite profile was analyzed using high-performance liquid chromatography (HPLC) with diode array detector (DAD) and thin layer chromatography (TLC), while secondary metabolites were studied by phytochemical test. The phytochemical results showed that there were no differences in metabolites in dried and fresh R. apiculata leaves. Crude extract of fresh and oven-dried gave 10 spots on the TLC, while sun-dried crude extract had 9 spots. The one missing spot (Rf value of 0.79) in the sun-dried crude extract might have unstable compounds that are easily degraded or damaged by the sunlight. Moreover, HPLC chromatogram indicated the pre-drying treatment gave alteration to the R. apiculata metabolites that only detected at 400 nm. Cytotoxic assay against P388 murine leukemia cell indicated that oven-dried treatment gave the best anticancer activity with IC50 value of 0.0323 mg/mL.

Abstract. Chantarasiri A. 2020. Species identification of stranded seaweeds on eastern seashores of Thailand and utilization as a sole carbon source for single-cell oils synthesized by oleaginous yeasts. Biodiversitas 21: 2353-2361. Many stranded seaweeds are left to decompose on the seashore. This study aimed to identify and utilize the stranded seaweeds collected from seashores in Rayong Province on the east coast of Thailand. Seaweeds were identified as Dictyota dichotoma strain A and Padina australis strain B based on their distinctive morphology and 18S rDNA sequence analyses. The most abundant seaweed, D. dichotoma strain A, was analyzed for chemical compositions following AOAC standard methods. This seaweed was considered a low-cost carbon source for the cultivation of three oleaginous yeasts without any other nutrient supplements. All oleaginous yeasts utilized the carbon source from Dictyota medium for growth and accumulation of single-cell oils (SCOs). The oleaginous yeast, Cryptococcus albidus strain TISTR 5103 accumulated SCOs at 51% (w/w). The resulting SCOs from oleaginous yeasts comprise many fatty acids with 10 to 22 carbon atoms. This study is the first to identify stranded seaweeds in Rayong Province using morphological and genetic techniques. Results showed the potential application of stranded seaweeds as a low-cost carbon source for SCO biosynthesis of oleaginous yeasts.

Published: May 2020

In this paper, a depth-related uniform multiple wavefront recording plane (UM-WRP) method is proposed for enhancing the image quality of point cloud-based holograms. Conventional multiple WRP methods, based on full-color computer-generated holograms, experience a color uniformity problem caused by intensity distributions. To solve this problem, the proposed method generates depth-related WRPs to enhance color uniformity, thereby accelerating hologram generation using a uniform active area. The aim is to calculate depth-related WRPs with designed active area sizes that then propagate to the hologram. Compared with conventional multiple WRP methods, reconstructed images have significantly improved quality, as confirmed by numerical simulations and optical experiments.

Emblemas e pedagogia seráfica: a convergência de dois mundos nas livrarias franciscanas da Província de Santo Antônio do Brasil no Setecentos (Bahia, Pernambuco e Paraíba)
Authors: Oliveira Carla Mary Silva
Published: May 2020

Desde o século XV a Emblemática tornou-se um dos muitos temas de interesse da cultura humanista cultivada entre a nobreza e os homens de letras na Europa do Renascimento e, depois, nas centúrias seguintes, do Barroco. Entre os religiosos, especialmente no que diz respeito às ordens conventuais e congregações que primavam pela formação instrucional de seus quadros, como inacianos e franciscanos, percebeu-se as enormes possibilidades do uso da Emblemática não apenas no desenvolvimento intelectual de seus noviços, mas também no trabalho de catequese a ser feito no mundo laico, especialmente no Novo Mundo. A intenção deste trabalho é discutir a presença de algumas obras de Emblemática no acervo das livrarias conventuais da Província Franciscana de Santo Antônio do Brasil listados no Livro dos Inventários dos Conventos do Norte [em 5 de julho de 1852] – elaborado pelo Fr. Antônio da Rainha dos Anjos Machado, documento este existente no Arquivo Provincial Franciscano do Recife – analisando-os sob a perspectiva da Pedagogia Seráfica cristalizada nos Estatutos da Província de S. Antonio do Brasil, publicados em Lisboa em 1709, e nas Atas Capitulares Provinciais (1649-1893), publicadas na Revista do IHGB em 1970.

O texto objetiva revelar particularidades históricas da Província das Alagoas no que diz respeito à presença de alunos órfãos, pretos e pardos nas chamadas aulas avulsas do ensino secundário, ainda na primeira metade do século XIX. A pesquisa consistiu, sobretudo, na localização, transcrição e análise de mapas escolares das aulas de Gramática Latina tanto da capital quanto do interior da Província, produzidos entre 1844 e 1847, pelos professores da época. Os referidos mapas encontram-se acondicionados no Arquivo Público de Alagoas, Brasil. Utilizando os aportes teórico-metodológicos de Fonseca (2007), Veiga (2008) e Cruz (2009), buscamos redimensionar a situação e ação social dos negros para além da escravização e marginalização, tendo em vista que também eles estiveram inseridos no processo de escolarização e civilização.
Educação e Mudança social: reflexões sobre o último meio século
Authors: Silva Camila Ferreira da , Rumbane Sebastião Juvêncio
Published: May 2020

A educação, enquanto área do conhecimento ou espaço acadêmico específico, tem sua história de constituição assinalada por uma confluência de diferentes campos do saber e notadamente seu caráter multirreferencial exprime uma de suas principais marcas, a qual vem sendo reiterada em diferentes épocas e contextos acadêmicos e científicos (SILVA, 2017). Neste sentido, no último século temos assistido a uma multiplicação de subáreas, temas, objetos e de aportes epistêmicos, teóricos e metodológicos nas pesquisas educacionais. Naturalmente este cenário nos fala de uma diversidade de pesquisadores ocupados com questões bastante heterogêneas entre si, o que acaba por levantar uma interrogação: há algumas inquietações que liguem esses sujeitos? Poderíamos ensaiar algumas respostas para tal pergunta, e provavelmente nos encontraríamos ponderando sobre a importância da educação, seu papel nos âmbitos individual e social, seus sentidos para distintos grupos sociais e seus direcionamentos historicamente situados. Nessa linha, o professor Michael Whitman Apple tem se ocupado, mais detidamente desde a década de 1980 , a pensar o poder que a educação exerce na sociedade capitalista. Sua mais nova obra traduzida para o português e lançada no Brasil no final de 2017, “A educação pode mudar a sociedade?”, constitui uma importante e madura produção nesta linha de pesquisa a que Michael Apple vem se dedicando há quase meio século, a presente resenha tem, pois, o objetivo central de apresentar criticamente a supracitada obra e o impacto de tal tradução para o público brasileiro e também para outros países de língua portuguesa.
Genealogia como exercício de contramemória: Afrânio Peixoto e a emergência da escola (1932-1942)
Authors: Gondra José Gonçalves
Published: May 2020

Neste artigo, exploro alguns princípios narrativos contidos no manual Noções de História da Educação, objeto de três reedições sucessivas (1933, 1936 e 1942), de autoria do polígrafo, Afrânio Peixoto, resultante dos três anos de sua vida (1932-1934) dedicados ao ensino de história da educação no Instituto de Educação do Rio de Janeiro. Nesta narrativa, Peixoto oferece às futuras professoras aquilo que designa como uma “história da civilização”, capital considerado necessário para que compreendessem a “ponta extrema do passado” e outros presentes, condição para se obter uma maior profissionalização da docência. Com este investimento, trabalho no registro de uma espécie de origem da escola, de fundação primeira, operando com marcos fundamentais destinados a comprovar a substância e funções deste acontecimento. No presente exercício, procuro desfazer a perpetuação imóvel de uma suposta identidade e funcionamento da escola, suspensa no tempo, para tentar pensar nas operações historiográficas e movimento pedagógico aos quais o referido manual se filia e que ajuda a legitimar e reproduzir.

Novel coatings containing silver nanoparticles (AgNPs) with strong bonding and controllable antibacterial activity on polyamide 6,6 fabric were produced by dielectric barrier discharge (DBD) plasma-assisted deposition at atmospheric pressure and hexamethyldisiloxane (HMDSO) layers. Silver ion release was tuned using a “sandwich” coating structure to prolong the antibacterial effect. The novel spray-assisted deposition increased deposition rates of AgNPs using atmospheric pressure DBD plasma treatment when an HMDSO layer was applied. An increase in AgNPs deposition in plasma treated samples and antimicrobial activity against Gram-negative ( Escherichia coli) for samples with an additional HMDSO layer was observed. These coatings allow the development of new and safe wound dressings able to switch the antimicrobial effect against Gram-positive and Gram-negative bacteria by washing the dressing at high temperature (75 °C) before application.
Medical Tourism in the Context of National Health Systems` Institutional Characteristics
Authors: OSADCHUK M. A. , OSADCHUK A. M. , TRUSHIN M. V.
Published: May 2020

Medical tourism (MT) is a modern type of medical services outside the state of residence. It links medicine and tourism. Moreover, its availability combined with economic feasibility is the main incentive for seeking medical care outside the place of residence and is an important issue for national health systems. A noticeable MT contribution to the country`s economy is possible if there is a well-thought-out infrastructure with introduction of certification procedure, a universal service and marketing system, an adequate response to the offer of additional tourism services and regulation of conditions for systematic cooperation with private intermediaries. However, the absence of interstate standards for this type of medical care leads to significant ethical, political, epidemiological and economic problems and makes it difficult to assess its professional quality. This necessitates the creation of a legal framework that takes into account the rights and responsibilities of both the medical services consumer and the host country.

Published: May 2020

Relations between Bali and China have been established since the Han Dynasty around 100 BC. This opinion was strengthened by the discovery of nekara, a bronze kettle drum, in Pejeng, Gianyar. The relationship between Bali and China is a trade relation in which Bali was written in the notes of Chinese traders who came to Southeast Asia in the 5th century. One of the legacies of Chinese trade in Bali is the uang kepeng (ancient Chinese coin) which was used as a means of a transaction at that time. The existence of uang kepeng in Bali is very interesting to discuss because of the transformation of its function. Previously uang kepeng functioned as a tool for trading transactions transformed into a means of transactions in religious rituals. This research used the method of observation, literature study, and in-depth interviews to reveals the existence and role of uang kepeng or pis bolong in Bali. At present, uang kepeng has also become a craft commodity that has a role in tourism in Bali.

Essential oils are aromatic compounds widely used in the perfumery, pharmaceutical and food industries. There are several methods to extract essential oils and extracts. These methods include distillation, pressure or scraping, pressing and razor technique, headspace solid-phase micro extraction (HS-SPME), solvent extraction, extraction by bioactive hydrolyzing enzymes, and CO2 extraction. The aim of this study was to investigate the amounts of active ingredients of essential oils of medicinal plants Ziziphus nummularia and Ziziphus spina-christi by HS-SPME so that it can more easily move towards production of effective herbal remedies by identifying the main and active ingredients of the plants. The main chemical compound of Z. spina-christi essential oil was found to be trans-caryophyllene (17.31%), followed by alpha-pinene (15.50%), beta-caryophyllene (10.86%), and beta-pinene (7.32%). The main compound of Z. nummularia essential oil was tetradecane (16.76%), followed by hexadecane (9.35%), dl-limonene (5.75%), cyclohexan-1-ol, 3 meth (5.54%), trans-caryophyllene (5.47%), and beta-myrcene (5.28%). Chemical compounds of Ziziphus spina-christi included carbobicyclic or bicycleheptane, sesquiterpenes derived from germacrene, bicyclic monoterpenes, and monoterpenes, while the main compounds of Z. nummularia included monoterpenes, aliphatic hydrocarbons, alkane hydrocarbons, primary terpene compounds, and decarbonated alcohol. Identification of chemical and biological constituents of essential oils of medicinal plants is a valuable way to identify medicinal compounds that can be used to treat diseases by combining the traditional effects and the main compounds in the experimental pharmacy studies.

The phenomenon of responsibility: between incontinence and hypercontrol
Authors: Leontiev Dmitry
Published: May 2020

The paper contains a phenomenological and theoretical analysis of responsibility treated as the capacity of personal causation (taking the role of the cause of one’s actions) based upon conscious awareness and self-detachment from the immediate stream of one’s living. The manifestations of the lack of responsibility are the failure to manage one’s actions in the face of multiple forces majeures, incontinence ofimmediate wishes and impulses, or rigid hypercontrol over these impulses. Special sections are devoted to interrelations between responsibility and freedom, especially in the developmental aspect, and responsibility for another person.

IUPAC Periodic Table Challenge
Authors: Meija Juris , Garcia-Martinez Javier , Apotheker Jan
Published: May 2020

In 2019, the world celebrated the International Year of the Periodic Table of Chemical Elements (IYPT2019) and the IUPAC centenary. This happy coincidence offered a unique opportunity to reflect on the value and work that is carried out by IUPAC in a range of activities, including chemistry awareness, appreciation, and education. Although IUPAC curates the Periodic Table and oversees regular additions and changes, this icon of science belongs to the world. With this in mind, we wanted to create an opportunity for students and the general public to participate in this global celebration. The objective was to create an online global competition centered on the Periodic Table and IUPAC to raise awareness of the importance of chemistry in our daily lives, the richness of the chemical elements, and the key role of IUPAC in promoting chemistry worldwide. The Periodic Table Challenge was the result of this effort.
Two new forms of ordered soft separation axioms
Authors: Al-shami Tareq M. , El-Shafei Mohammed E.
Published: May 2020

The goal of this work is to introduce and study two new types of ordered soft separation axioms, namely soft Ti-ordered and strong soft Ti-ordered spaces (i = 0, 1, 2, 3, 4). These two types are formulated with respect to the ordinary points and the distinction between them is attributed to the nature of the monotone neighborhoods. We provide several examples to elucidate the relationships among these concepts and to show the relationships associate them with their parametric topological ordered spaces and p-soft Ti-ordered spaces. Some open problems on the relationships between strong soft Ti-ordered and soft Ti-ordered spaces (i = 2, 3, 4) are posed. Also, we prove some significant results which associate both types of the introduced ordered axioms with some notions such as finite product soft spaces, soft topological and soft hereditary properties. Furthermore, we describe the shape of increasing (decreasing) soft closed and open subsets of soft regularly ordered spaces; and demonstrate that a condition of strong soft regularly ordered is sufficient for the equivalence between p-soft T1-ordered and strong soft T1-ordered spaces. Finally, we establish a number of findings that associate soft compactness with some ordered soft separation axioms initiated in this work.
S100A6 promotes proliferation and migration of HepG2 cells via increased
ubiquitin-dependent degradation of p53
Authors: Song Dongqiang , Xu Beili , Shi Dongmin , Li Shuyu , Cai Yu
Published: May 2020

Purpose

S100A6 protein (calcyclin), a small calcium-binding protein of the S100 family, is
often upregulated in various types of cancers, including hepatocellular carcinoma
(HCC). The aim of this study was to illustrate the molecular mechanism of S100A6
in regulating the proliferation and migration of HCC cells.

Methods

The expressions of S100A6 in human HCC and adjacent non-tumor liver specimens were
detected using immunoblotting and quantitative PCR (qPCR). The recombinant
glutathione S-transferase (GST)-tagged human S100A6 protein was purified and
identified. After treatment with S100A6, the proliferation of HepG2 cells was
detected by the MTT and colony formation assay, and the migration of HepG2 cells
was investigated by the transwell migration assay; the protein levels of cyclin D1
(CCND1), E-cadherin, and vimentin were also tested by immunoblotting. The effect
of S100A6 on p21 and nuclear factor-κB pathway was verified by performing
the dual luciferase assay. Then, the expression of p21 and its transcription
activator, p53, was examined using immunoblotting and qPCR, the ubiquitination of
which was investigated through co-immunoprecipitation.

Results

It was found that the level of S100A6 was higher in the HCC tissues than in the
adjacent non-tumor liver specimens. Exogenous overexpression of S100A6 promoted
the proliferation and migration of HepG2 cells. S100A6 was observed to regulate
p21 mRNA and protein expression levels and decrease p53 protein expression level,
not mRNA level, by promoting the ubiquitination of p53 via the
proteasome-dependent degradation pathway.

Conclusion

Our study indicated that S100A6 overexpression could promote the proliferation and
migration of HCC cells by enhancing p53 ubiquitin-dependent proteasome
degradation, ultimately regulating the p21 expression level.

Published: May 2020

Recently, sonochemistry has been used for the synthesis of inorganic compounds, such as zinc borates. In this study using zinc sulphate heptahydrate (ZnSO4·7H2O) and boric acid (H3BO3) as starting materials, a zinc borate compound in the form of Zn3B6O12·3.5H2O was synthesized using an ultrasonic probe. Product’s characterization was carried out with using X-ray diffraction (XRD), Scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FT-IR) and Raman spectroscopy. Zinc borate compound’s chemical bond structure was observed with Raman and FTIR. From the XRD results it was seen that Zn3B6O12·3.5H2O can be quickly synthesized upon heating at 80°C and 85°C (55 min) or 90°C (45 min) in very high yield (>90%). The minimum particle size obtained was ~143 μm from the SEM results. Zinc borate compound was synthesized at a lower temperature in less time than other synthesized zinc metal compound in literature.

Information regarding the interaction between biological nitrogen fixation (BNF) with Azospirillum brasilense inoculation and the use of silicon (Si) is needed. Silicon exerts numerous benefits on grasses, especially when the plants are subjected to biotic and abiotic stresses, affecting plant nutrition. The aim of this research was to determine if there is a synergistic effect between the inoculation with A. brasilense and Si use, on macro-nutrient content in corn shoot and root. The field trial was performed in Selvíria, Brazil, on a Typic Rhodic Hapludox soil under no-till system. The experimental design was a completely randomized block design with four replicates arranged in a 2 × 5 × 2 triple factorial arrangement, consisting of two soil acidity corrective sources (dolomitic limestone and Ca and Mg silicate as sources of Si); five N doses (0, 50, 100, 150 and 200 kg ha-1 applied in topdressing); with and without seed inoculation with A. brasilense. The inoculation favored N concentration in shoots and increased the N and S concentration even when associated to high N rates in topdressing. The Si as Ca and Mg silicate associated with the increment of N rates does not promote an increase in the macronutrients uptake. Although it did not favor the N use, the Si also did not negatively affect the benefits of the A. brasilense.
Living and Nonliving Occasionalism
Authors: Weir Simon
Published: May 2020

Graham Harman’s Object-Oriented Ontology has employed a variant of occasionalist causation since 2002, with sensual objects acting as the mediators of causation between real objects. While the mechanism for living beings creating sensual objects is clear, how nonliving objects generate sensual objects is not. This essay sets out an interpretation of occasionalism where the mediating agency of nonliving contact is the virtual particles of nominally empty space. Since living, conscious, real objects need to hold sensual objects as sub-components, but nonliving objects do not, this leads to an explanation of why consciousness, in Object-Oriented Ontology, might be described as doubly withdrawn: a sensual sub-component of a withdrawn real object.
Characterization of the effects of a plasma injector driven by AC dielectric barrier discharge on ethylene-air diffusion flame structure
Authors: Zheng Zhi , Nie Wansheng , Zhou Siyin , Tian Yuan , Zhu Yangzhu , Shi Tianyi , Tong Yiheng
Published: May 2020

A dielectric barrier discharge plasma controlled diffusion flame experimental system was built based on the designed coaxial swirling plasma injector. The air plasma was generated within the annulus gap of the injector by alternating current dielectric barrier discharge. The discharge characteristics and power of plasma injector under different actuation intensities and air flowrates were measured. Through the measurement techniques, such as schlieren imaging, broadband chemiluminescence image and CH* chemiluminescence, the effect and mechanism of plasma on ethylene-air normal diffusive jet and flame was explored. The results showed that a large number of filamentary discharge channels are formed in air plasma. The increase of air flowrates weakened the intensity of discharge to a certain extent. The induced jet generated by the plasma can short the laminar length of the ethylene-air jet, accelerate the transition of the flow jet, enhance the turbulence and the mixing of the fuel and the oxidizer. The higher the actuation intensity, the shorter distance of the cold jet transition zone, the higher the jet turbulence. Depending on the aerodynamic and kinetic effects, plasma can improve the stability of ethylene-air diffusive flame and reduce the lift height between the flame root and injector. The plasma can also expand the flammability limit of ethylene-air flame and make the flame ignited under some conditions that could not be. In addition, the CH* chemiluminescence shows that, in a certain range of discharge voltage, the heat release distribution can be changed on both sides of the flame, and its representative length are generally reduced as the voltage rises. On the contrary, the overtop voltage could lead to a decrease of flame heat release.
On the spectrum of noisy blown-up matrices
Authors: Fazekas István , Pecsora Sándor
Published: May 2020

We study the eigenvalues of large perturbed matrices. We consider a pattern matrix P, we blow it up to get a large block-matrix Bn. We can observe only a noisy version of matrix Bn. So we add a random noise Wn to obtain the perturbed matrix An = Bn + Wn. Our aim is to find the structural eigenvalues of An. We prove asymptotic theorems on this problem and also suggest a graphical method to distinguish the structural and the non-structural eigenvalues of An.

Published: May 2020

Respiratory Disease is the leading cause of death in the majority of people and is among the top 10 causes of death in the world. Factors causing respiratory disease are occupational exposure, smoking and lung infections. According to WHO, 65 million people have respiratory illnesses ranging from moderate to severe. Nearly 90% of deaths from respiratory illness occur in low- and middle-income countries.
