The paper considers the findings of studies on ecological-morphological structure of microphytobenthos in Telbin Lake located in the residential community of Kyiv city.

The research study aimed to distinguish ecological-morphological groups of algae in microphytobenthos of the human-impacted waterbody within the urban area and to evaluate the role of microphytobenthos structural components in forming a certain type of algal community.

Microphytobenthos was sampled with the MB-TE microbenthometer within the littoral area at aquatic-vegetation-free sites and within the deep-water area of the lake.

Algae sampling and laboratory processing of samples were performed in accordance with the methods generally accepted in hydrobiology. For diatoms identification permanent slides were made with special high-resolution mounting media. Ecological-morphological groups of benthic algae were distinguished considering the habitats of algae. The relative share in the microphytobenthos species richness was calculated for each group.

The degree of human impact on the lake ecosystem was evaluated according to the proven method, consisting in distinguishing the total number of factors, which most frequently affect the lake ecosystem.

The findings of studies on the ecological-morphological structure of microphytobenthos in Telbin Lake have made it possible to distinguish 7 ecological-morphological groups of algae. The species richness is mainly formed by periphytont and plankton, and benthonts are for the most part represented by the ecological-morphological group of eurytopic littoral diatoms. In the high-degree human impact waterbody (8 points) the share of benthonts’ major ecological-morphological groups in the species richness decreases in 1.6–2 times, and the shares of periphyton and plankton increase 1.3–2-fold respectively, as compared with low-degree human impact waterbody (3 points).

The resulting unstable algal community consisting mainly of species getting to the lake bottom from other habitats is defined as algal aggregation, which is indicative of unfavorable conditions for residential algal flora development.

Various waterbodies of Ukraine can differ significantly in the environmental variables playing a determining role in microphytobenthos structure and abundance.

Microphytobenthos may act as a reliable biological indicator of aquatic ecosystem’s disturbance caused by human pressure upon waterbodies, responding to such pressure with the transformation of its structural elements.

For several waterbodies of Ukraine detailed analysis of microphytobenthos ecological-morphological structure made it possible to characterize bottom algal communities and to distinguish algal cenoses, which allowed to assess ecological state deterioration in different areas of the waterbodies under study.

The information on the microphytobenthos structural components of urban lakes is scarce.

Therefore, studying the ecological-morphological structure of microphytobenthos in various waterbodies within Kyiv city is of high importance.

In the gynoecium of L. aestivum there are synascidiate, hemisynascidiate, symplicate, and asymplicate vertical zones. The longest zone is the fertile hemisynascidiate zone and the shortest is the synascidiate zone in the ovary. It was discovered that in L. aestivum the peduncle consists of 12 vascular bundles, which are reorganized into two circles of bundles, the outer with massive leading bundles, departing as dorsal bundles of perianth, traces of perianth tepals and septal bundles of carpels and inner circle of bundles over the nests are divided into three groups of ventral carpel bundles are lined up on four, which are located in the center of the ovary and providing nutrition to the ovules. Dorsal carpels bundles are double. Above the locule, ventral bundles of the carpel, as well as the double septal bundles, merge with the dorsal bundles and form a dorsal vein. The outer tepals of the simple perianth have nine vascular traces, and the inner tepals of the perianth have eight vascular traces. Traces of stamens are single-bundle, formed from traces of perianth tepals. The ovary has features of the early stages of fruit morphogenesis and adaptation to disclosure, such as differentiation of mesocarp and endocarp cells, double dorsal bundles of carpels. Structural flower features related to pollen proposal as reward pollinators. Since ovary is a structural basis of the fruit, histological ovary wall differentiation reflects the features of the subsequent morphogenesis of the fruit.
In Search of the Perfect Curry: A Gender Perspective on Durban Curry in Two Contemporary Cookbooks
Authors: Reddy Vasu , Moletsane Relebohile
Published: March 2021

The article focuses on the meanings of the curry in two contemporary cookbooks, Durban Curry (2014) and Durban Curry: Up2Date (2019). These texts are read partly in conjunction with Indian Delights (originally published in 1961), a pioneering volume focusing on Indian food, which serves as an intertext to the books analysed in this article. The article offers a textual and symptomatic gendered reading that describes some representational and discursive aspects of curry-making as shown in the foodways and foodscapes presented in the two cookbooks. The article motivates that the meaning of curry is not in its singularity, but is instead in the plurality of its shifts, changes, appropriations and mobility over time.
Single-Cell Adhesion Force Mapping of a Highly Sticky Bacterium in Liquid
Authors: Ishii Satoshi , Yoshimoto Shogo , Hori Katsutoshi
Published: March 2021

The highly sticky bacterium Acinetobacter sp. Tol 5 adheres to various material surfaces via its cell surface nanofiber protein, AtaA. This adhesiveness has only been evaluated based on the amount of cells adhering to a surface. In this study, the adhesion force mapping of a single Tol 5 cell in liquid using the quantitative imaging mode of atomic force microscopy (AFM) revealed that the strong adhesion of Tol 5 was several nanonewtons, which was outstanding compared with other adhesive bacteria. The adhesion force of a cell became stronger with the increase in AtaA molecules present on the cell surface. Many fibers of peritrichate AtaA molecules simultaneously interact with a surface, strongly attaching the cell to the surface. The adhesion force of a Tol 5 cell was drastically reduced in the presence of 1% casamino acids but not in deionized water (DW), although both liquids decrease the adhesiveness of Tol 5 cells, suggesting that DW and casamino acids inhibit the cell approaching step and the subsequent direct interaction step of AtaA with surfaces, respectively. Heterologous production of AtaA provided non-adhesive Acinetobacter baylyi ADP1 cells with a strong adhesion force to AFM tip surfaces of silicon and gold.
Abnormal Effect of Phase Transition on Thermal Transport in Soft Porous Crystals
Authors: Ying Penghua , Zhang Jin , Zhong Zheng
Published: March 2021

Soft porous crystals (SPCs) have attracted a lot of attention recently due to their great potential for a wide range of gas storage and separation applications. They can undergo large-amplitude phase transitions under external stimulus such as mechanical pressure, gas adsorption, and temperature while retaining their structural integrity. However, the thermal conductivity of SPCs is usually very low, owing to the porous structure and weak coordination bond, which would heavily influence their work performance. Hence, understanding the thermal transport in SPCs especially considering their dynamic features becomes extremely crucial. In this paper, taking the isorecticular DUT series as an example, the effect of phase transition from the large pore (lp) phase to narrow pore phase (np) on thermal transport in SPCs is comprehensively investigated by molecular dynamics (MDs) simulation together with the Green-Kubo method. According to our calculations, all DUT structures exhibit an ultralow thermal conductivity (). Specifically, we demonstrate here that the np phase of DUT-48 crystal after phase transition has a larger density but owns a smaller thermal conductivity. This abnormal effect of phase transition is in contrast to the previous finding that the SPCs with larger density possess a larger thermal conductivity. For other DUT crystals including DUT-47, DUT-49, DUT-50, and DUT-151, the np phase is found to have a higher thermal conductivity than their lp phase counterpart, which are as expected. This complicated effect of phase transition on thermal transport in SPCs can be explained by a porosity-dominated competition mechanism between the increased volumetric heat capacity and the aggravated phonon scattering during the phase transition process. This finding is expected to fill the gap in understanding the complicated effect of phase transition on the thermal transport in SPCs.

Programmed cell death via apoptosis is a natural defence against excessive cell division, crucial at all stages of life from foetal development to maintenance of homeostasis and elimination of precancerous and senescent cells. Here we demonstrate an electrified liquid bio-interface that replicates the molecular machinery of the inner mitochondrial membrane at the onset of apoptosis. By mimicking in vivo cytochrome c (Cyt c) interactions with cell membranes, our platform allows us to modulate the conformational plasticity of the protein by simply varying the electrochemical environment at an aqueous|organic interface. As proof-of-concept, we use our electrified liquid bio-interface to identify drug molecules that can potentially downregulate Cyt c and protect against uncontrolled neuronal cell death in Alzheimer’s disease and other neurodegenerative disorders.

According to the Annual Report of the National Commission on Anti-Violence Against Women, cases of sexual violence continue to increase each year. The data shows that Indonesia needs regulations that protect victims of sexual violence. So far there has been no legislation that accommodates the whole of crimes and sexual violence resulting in a vacancy and uncertainness of the law. Indonesia needs laws that can complement its special nature governing and carrying out all forms of sexual violence (lex specialis propensionem sexualem identitatemque). So the existence of laws specifically governing sexual violence is critical to providing guaranteed protection and legal certainty for victims of sexual violence in a more perfect range. The withdrawal of the MCC Bill from Prolegnas is clearly not the answer to the growing problem of sexual violence. So by conducting this research will be a clue to the urgency of the Sexual Violence Elimination Bill which encourages the certainty of legalization. This research conducted by library review method which will produce a research analysis of the impact that will occur due to the delay in the ratification of the MCC Bill with the enactment of the Criminal Law Bill (RKUHP) as it is currently.

Por um Lugar ao Sol: A política Externa Alemã de Otto Von Bismarck à Guilherme II
Authors: Zahreddine Danny , Starling Bruno Pimenta
Published: March 2021

A Alemanha, após o seu processo de unificação, concluído em 1871, passou por um intenso crescimento e desenvolvimento até as vésperas da Primeira Guerra Mundial. Sempre orientados por uma percepção da distribuição de poder dentro do sistema internacional, seus líderes procuraram implementar uma política externa visando a ampliar o poder do país de forma a encontrar um melhor posicionamento relativo no sistema. Primeiramente, Bismarck buscou a manutenção do status quo pós-Guerra Franco-Prussiana, cujo resultado colocou a Alemanha em posição destacada na Europa. Já sob Guilherme II, uma política externa mais ambiciosa procurou promover internacionalmente o Império como uma potência de nível mundial. Condições internas e externas facilitaram e/ou dificultaram este processo. A elaboração de uma política de alianças, a intensificação da extração e da mobilização de recursos sociais, o estímulo a um nacionalismo de Estado, o combate a ideologias tidas como perigosas e o fortalecimento das estruturas e instituições do novo Império Alemão foram elementos extremamente importantes para transformar o que outrora era um emaranhado de Estados sem muita relevância política em uma potência mundial já em fins do século XIX.

This article analyses the archaeological sites with rock art with the presence of representations called here “Pirogas”, looking for an association between these figures and the past fluvial context of Carnaúba river valley (Brazil). The research aims to identify the viability of navigation in the past paleoenvironment of the drainage networks of the Carnaúba river valley. Through the collection and interpretation of primary and secondary data and their manipulation through the use of georeferencing in a GIS environment, it was possible to verify that over different epochs of the Holocene, in climatic conditions of greater humidity and better rainfall distribution, the Carnaúba river possibly had flower conditions and flood regimes more durable than the present, favouring better subsistence conditions and the possibility of its use for navigation purposes. However, the need for further studies on environmental reconstruction of the archaeological area is reaffirmed and new problems related to the interpretation of the region’s rock art records are presented.

A ampliação do gergelim (Sesamum indicum) no Brasil é dificultada por problemas relacionados ao manejo de plantas daninhas. Assim, o objetivo foi avaliar a seletividade de herbicidas aplicados em pós-emergência no gergelim, bem como a resposta produtiva da cultura ao controle das plantas daninhas. Primeiramente, avaliou-se o comportamento do gergelim para diferentes herbicidas. Na sequência, a cultura foi submetida a diferentes doses do herbicida de maior seletividade (sethoxydim). Em campo, verificou-se o efeito das plantas daninhas sobre a cultura por meio dos tratamentos: testemunha, capinado e herbicida sethoxydim. As variáveis foram fitotoxicidade aos 7, 14, 21 e 28 dias após o tratamento (DAT), massa seca da parte aérea, altura de plantas, peso de mil sementes e produtividade. Imazethapyr, mesotrione, bentazon, carfentrazone-ethyl e 2,4-D, quando aplicados em pós-emergência, não são foram seletivos para o gergelim. Sethoxydim foi seletivo entre 220,8 - 883,2 g i.a. ha-1, entretanto não proporcionou ganhos produtivos.

Equações de perfil do tronco das árvores viabilizam quantificar diferentes usos que se possam destinar a produção madeireira de um determinado povoamento florestal. São advindas do ajuste de modelos de taper, referenciados como: modelos de afilamento, adelgaçamento, forma e, ou de perfil do tronco ou do fuste. Como não se encontram estudos sobre o emprego de equações de perfil do tronco em plantios brasileiros com Corymbia citriodora, esse trabalho objetivou verificar o ajuste de uma grande quantidade de modelos para esta importante espécie florestal. Foram utilizadas 35 árvores cubadas com medições diretas do diâmetro do tronco nas posições: 0,2 m, 0,4 m, 0,7 m, 1,3m, 2,7 m e a cada 2 metros até um valor aproximado de 1,0 cm com casca. Como critérios estatísticos de avaliação das equações de perfil do tronco geradas para C. citriodora, foram considerados: coeficiente de determinação ajustado, erro padrão da estimativa, distribuição gráfica dos resíduos, média dos desvios absolutos, desvio padrão das diferenças, soma dos quadrados dos resíduos relativos, média dos desvios percentuais, raiz quadrada do erro médio, viés e coeficiente de correlação linear múltipla. Concluiu-se que, para descrever o perfil do tronco de C. citriodora, as equações geradas por modelos muito difundidos no Brasil apresentaram desempenho insatisfatório e que se destacaram seis modelos ainda pouco testados ou sem aplicação no país.

Lectio Praecursoria: Patchworks of Care: Ethics and practice of care in the organic food movement in Latvia
Authors: Bankovska Agnese
Published: March 2021

The thesis introduced in this lectio praecursoria explores the everyday work, ideals and values of the Latvian organic food movement known as tiešā pirkšana (‘direct purchasing’), an initiative which aims to shorten the physical and symbolic distance between producers and consumers; producers, market and regulating policies; and consumers and food. Drawing on the empirical material obtained through long-term ethnographic fieldwork, and theoretical discussions in social and food research, the concept of ‘reconnection’ was chosen to analyse the process of shortening the distance between the different actors involved in one small-scale food provisioning system. By focusing on the notion that there is a link between the reconnection process and the ethics and practice of care, the thesis analyses different forms of care in the various stages of food provisioning in the TP movement.

Keywords: mall-scale food provisioning, care and food, spatiotemporalities of care, everyday food practices

OLİVİNİN REFRAKTER HAMMADDESİ OLARAK KULLANIMI İÇİN DEMİR İÇERİĞİNİN MANYETİK AYIRMA İLE AZALTILMASI
Authors: Acar İlker
Published: March 2021

Bu çalışmada, kromit zenginleştirilmesinde nihai artık olarak elde edilen bir olivin numunesindeki demir içeriğinin manyetik ayırma yöntemleri ile azaltılabilme potansiyeli incelenmiştir. Bu kapsamda, öncelikle numune +212, -212+150 ve -150 µm olarak üç fraksiyona ayrılmıştır. Sonrasında iri boyutlara kuru, ince boyuta ise yaş manyetik ayırma uygulanmıştır. Sonuçlar manyetik olmayan fraksiyonun ağırlık yüzdesi, Fe2O3 içeriği ve demir giderimi (%) gibi parametreler kullanılarak değerlendirilmiştir. Ayrıca manyetik olmayan fraksiyonlardaki mineralojik fazların miktarlarındaki değişimler XRD analizleri ile belirlenmiştir. +212 ve -212+150 µm için optimum değerlere sırasıyla 0,50-0,75 ve 1,0-2,0 A akım şiddeti aralıklarında ulaşılabileceği tespit edilmiştir. Her ne kadar karşılaştırılabilir olmasa da, -150 µm için efektif ayırmanın 2,0-3,0 A aralığında sağlandığı görülmüştür. Küçülen tane boyutu ile azalan demir içerikleri elde edilen bu sonuçları doğrular niteliktedir. XRD desenlerindeki demir içeriği yüksek fazların pik şiddetlerindeki azalışların da yine manyetik ayırma sonuçları ile uyumlu olduğu tespit edilmiştir. Genel sonuçlar, olivince zengin numunedeki demir içeriğinin manyetik ayırma ile refrakter hammaddesi için gerekli sınır değerlere çekilebileceğini göstermiştir.
