Abstract:

O estudo teve como objetivo avaliar as condições microbiológicas de colchões caixa de ovo em uso hospitalar com a finalidade de identificar a presença de Staphylococcus aureus e seu fenótipo de resistência à meticilina (MRSA). Coletaram-se as amostras microbiológicas nos colchões por meio de placas de contato PetrifilmTM em posições pré-estabelecidas. Totalizou-se 180 placas coletadas em 15 colchões, das quais 139 (72,2%) foram positivas para Staphylococcus aureus. Desse total, 77 (55,4%) e 62 (44,6%) corresponderam respectivamente à coleta antes e após a lavagem dos colchões. Evidenciou-se redução significante (p=0,023) das Unidades Formadoras de Colônias (UFC), entretanto com relação ao perfil de resistência foi identificado 8 (53,3%) colchões com MRSA. Diante dos resultados, pode-se inferir sobre o risco destes colchões atuarem como reservatórios secundários na cadeia de infecção, especialmente no que se refere à presença de MRSA.

Abstract:

OBJETIVO: Verificar se existe contaminação por fungos antes e após limpeza e desinfecção terminal de colchões hospitalares utilizados por portadores de candidemia. MÉTODOS: Estudo transversal que investigou 25 colchões de diferentes unidades hospitalares e utilizados por pacientes com candidemia, confirmados por hemocultura. Utilizou-se amostragem por conveniência. Após crescimento em Ágar Sabouraud Dextrose as leveduras isoladas foram identificadas pelas características macroscópicas, microscópicas e fisiológicas. RESULTADOS: Totalizou-se 15 (60%) colchões contaminados com Candida spp. Desse total, 10 (66,7%) e cinco (33,3%) corresponderam respectivamente à coleta antes e após a desinfecção dos colchões, sendo que a espécie mais frequentemente isolada foi Candida parapsilosis. CONCLUSÃO: Considerando que a metade dos colchões permaneceram contaminados após o processo de limpeza e desinfecção, pode-se inferir sobre o risco destes atuarem como reservatórios secundários na cadeia de infecção.

Abstract:

O estudo procurou correlacionar as curvaturas da coluna vertebral nas posições deitada, em colchões de várias densidades, com a posição ortostática. Este estudo teve como objetivo verificar as alterações posturais da coluna vertebral, induzidas pelo uso de três colchões de diferentes densidades. Foram avaliadas 29 voluntárias, nos decúbitos ventral e lateral direito, bem como na posição ortostática, através da avaliação das imagens analisadas pela biofotogrametria computadorizada. Quando comparadas às angulações da coluna vertebral na posição ortostática com os decúbitos no colchão popular, verificou-se que houve diferença estatisticamente significante no aumento destas, porém, quando comparou-se a posição ortostática com os decúbitos nos colchões de densidades 28 e 33 kg/m3, não foram encontradas diferenças significantes. O que permiti-nos inferir que nos colchões de densidade 28 e 33 kg/m3 houve uma maior aproximação dos valores angulares à postura ortostática apresentada pelas voluntárias. Conclui-se, também, que houve diferença estatística dos valores angulares da coluna vertebral entre os colchões de densidade 28 e 33 kg/m3 quando comparados com o colchão popular, tendo como parâmetro à posição ortostática.Palavras-chave: colchão, coluna vertebral, densidade, postura

Abstract:

Os fluidos de perfuração base óleo têm sido utilizados em perfuração de poços de petróleo por apresentarem características como, lubricidade, fricção mecânica, inibição química, estabilidade do sistema, entre outras, pois minimizam inúmeros problemas durante a etapa de perfuração. Porém, o reboco formado pelo fluido de perfuração nas paredes do poço e o fluido contido em seu interior devem ser removidos de forma eficiente, propiciando uma boa cimentação, melhorando a aderência do cimento a formação e do cimento ao revestimento. Os colchões lavadores são fluidos que possuem propriedades químicas adequadas que atuam dispersando o reboco e o fluido de perfuração. Baseado nisto, este trabalho teve o objetivo de desenvolver colchões lavadores a base de óleo vegetal e tensoativos, para serem utilizados durante a operação de cimentação de poços de petróleo removendo o reboco formado pelo fluido de perfuração nas paredes do poço. Foram utilizados três tensoativos nas formulações dos colchões, um aniônico de origem vegetal (OCS) e dois não iônicos (TW80 e ASP80). E suas eficiências foram avaliadas a partir de testes de remoção. Dos resultados obtidos, verifica-se que os tensoativos OCS e ASP80 apresentaram valores satisfatórios de remoção de aproximadamente 77% e 97%, respectivamente. Sendo o OCS uma boa alternativa para uso em formulações de colchões lavadores, uma vez que este é um tensoativo de origem vegetal.

Abstract:

Através de meios de cultura, foi pesquisada a posição de colônias de Staphylococcus aureus em colchões, visando avaliar a eficácia do procedimento de limpeza e desinfecção dos leitos do Hospital Escola da Faculdade de Medicina do Triângulo Mineiro (Uberaba). Foram analisadas amostras de 50 colchões no período de 22 de outubro de 2000 a 16 de janeiro de 2001. As amostras foram coletadas e semeadas, pela técnica de esgotamento, em dois meios de cultivo (ágar sangue e manitol) com posterior realização de provas de catalase e coagulase . Na análise estatística, foram utilizados os testes não paramétricos Mann-Whitney, Kruswkal- Wallis e Wilcoxon Matched Pairs Test com nível de significância p < 0,05. Foram utilizadas 600 placas de meio de cultivo. Houve crescimento em 94 (15,6%), sendo 82 (87,2%) antes e 12 (12,8%) após a limpeza e desinfecção. Em relação à posição no leito, as amostras semeadas no meio de cultivo com manitol mostraram que não houve redução significativa na posição inferior do leito (p>0,05). Os resultados apontam e alertam para falhas no procedimento de limpeza e desinfecção dos leitos hospitalares por nós estudados.

Abstract:

INTRODUÇÃO: O meio ambiente hospitalar guarda uma íntima relação com as infecções hospitalares, podendo proporcionar focos de contato e de transmissão. Como a higiene representa uma das formas de controlar a contaminação ambiental, realizou-se estudo para avaliar as condições microbiológicas dos colchões hospitalares antes e depois de sua limpeza. MÉTODOS: Utilizaram-se, para a colheita dos espécimes, placas de contato -- Rodac-plate <FONT FACE="Symbol">¾</FONT> preparadas com meio de cultura ágar-sangue. Selecionaram-se os leitos de acordo com critérios previamente estabelecidos, e os locais de colheita sob o colchão foram escolhidos por sorteio aleatório. Aplicou-se o teste estatístico de Goodman para o estudo das alterações numéricas quanto a positividade das placas. RESULTADOS: Foram investigados 52 colchões, totalizando 520 placas, das quais 514 (98,8%) resultaram em culturas positivas, sendo que 259 corresponderam ao período anterior à limpeza e 255 ao período posterior ao procedimento. Houve redução de culturas positivas em apenas 4 placas. CONCLUSÕES: Os resultados obtidos sugerem que a limpeza, da forma como vem sendo conduzida, provoca o deslocamento da carga microbiana para outros pontos do colchão em vez de diminuí-la, resultando na manutenção da quantidade de microorganismos que existia anteriormente à limpeza.

Abstract:

RESUMO Este artigo trata da ação dos jatos formados em vertedouros tipo salto esqui sobre bacias de dissipação tipo fossa pré-escavada, dando especial ênfase às pressões hidrodinâmicas e sua caraterização junto ao fundo da bacia. Para estudar experimentalmente a ação dos jatos nas bacias de dissipação, utilizou-se de um modelo físico construído no Laboratório de Obras Hidráulicas do IPH/UFRGS com ensaios de diferentes vazões e cotas de fossas pré-escavadas. As pressões dinâmicas observadas no modelo físico foram comparadas com as calculadas por meio de metodologia teórica com a finalidade de avaliar a sua aplicação em projetos de engenharia, onde se observou grandes diferenças de magnitude da pressão quando em colchões rasos, e diferenças de distribuição de pressão ao longo do fundo da bacia de dissipação, principalmente quando em colchões profundos. No sentido de ajustar a metodologia aplicada, foi proposta a variação de parâmetros que regulam a forma do bulbo de pressões formado pelo jato e a aplicação de um coeficiente de amortecimento de pressões, sendo que assim foi possível melhorar significativamente a distribuição e a magnitude das pressões calculadas devidas à ação dos jatos no fundo da bacia de dissipação. Os resultados se mostram satisfatórios até determinada distância após o pico de pressão provocado pelo jato, porém após este ponto, os efeitos de ressalto hidráulico prevalecem e devem ser pesquisados em estudos futuros.

Abstract:

A Teoria das Restrições (TOC) possibilita identificar, controlar e gerenciar da melhor maneira os gargalos em qualquer sistema produtivo por meio de cincos passos para o gerenciamento das restrições. O objetivo do presente trabalho é aumentar o desempenho do processo produtivo com a eliminação dos gargalos através da aplicação da Teoria das Restrições e das diretrizes dos seus cinco passos de focalização em uma indústria de colchões situada no Rio Grande do Sul. A pesquisa foi realizada com cunho objetivo exploratório e descritivo à Teoria das Restrições, pesquisa-ação com intervenções e ainda outras técnicas de avaliação, análise e identificação para melhoria no processo, em que se apresentam como ferramentas de auxílio. Os resultados encontrados relacionam-se com a identificação dos gargalos, noção do processo gargalo e sua eliminação. Na etapa 2 da TOC 1 (realizada no setor de revisão e embalagem), a quantidade de peças por hora aumentou de 43 para 51 o que significa 18,6%, onde posteriormente na etapa 4 de 51 para 72 peças, ou seja, um aumento de 41%, em decorrência da compra de um embaladora automática, sendo que ainda nesta TOC, foi possível a redução de 5 para 3 funcionários. Com a TOC 2 (realizada no setor de montagem) a evolução de peças foi de 59 para 71, cerca de 24%, devido as mudanças de layout e fluxo de produção contando ainda com a redução de 17 para 11 funcionários no setor. Com os resultados obteve-se ganhos significativos em produtividade, melhorando-se assim a performance da unidade fabril

Abstract:

Neste trabalho, foram confeccionadas e testadas chapas aglomeradas estruturais utilizando partículas de Pinus elliottii Engelm com dimensões nominais de 110, 75 e 40 mm de comprimento, 0,5 e 1,0 mm de espessura e 20 mm de largura. As partículas foram orientadas ao acaso em moldes sem-fundo com dimensões de 50 x 50 x 20 cm. Os colchões foram prensados a 1800C por 10 minutos até atingir espessura de 9,5 mm e densidade de, aproximadamente, 0,7 g/cm3. O adesivo utilizado foi 8% (em relação ao peso seco das partículas) de tanino-formaldeído. Foram analisadas as propriedades de flexão estática, ligação interna, resistência ao arrancamento de parafusos, dureza Janka, inchamento em espessura e absorção d'água para 2 e 24 horas de imersão. Todos os testes foram realizados segundo a norma americana ASTM D 1037 (1995). As propriedades de flexão estática (MOR e MOE) aumentaram com o aumento do comprimento e diminuição da espessura das partículas. Já o inchamento em espessura e a resistência ao arrancamento de parafusos aumentaram com o aumento da espessura das partículas.

Abstract:

O objetivo do presente trabalho foi analisar o comportamento da temperatura nas faces e no miolo de chapas de partículas aglomeradas, coladas com 8% de adesivo (base peso seco das partículas) tanino-formaldeído. As chapas foram produzidas com três repetições por tratamento, com massa específica nominal de 0,7 g/cm³ e pressão específica de prensagem de 27 kgf/cm². Os tratamentos basearam-se na utilização de flocos de pinus (Pinus elliottii) e partículas de eucalipto (Eucalytus sp), sendo que os flocos de pinus apresentavam três diferentes comprimentos nominais (40, 75 e 110 mm) e duas espessuras (0,5 e 1,0 mm). Também foram analisados duas temperaturas de prensagem (140 e 180°C) e dois teores de umidade nominal do colchão (17 e 21%). A temperatura no interior dos painéis durante a prensagem foi obtida por meio de fios para termopares tipo K (cromo-alumel). Os gráficos da temperatura em função do tempo de prensagem mostraram uma rápida elevação da temperatura nos primeiros 100 segundos de prensagem, mantendo-se num plateau possivelmente após atingir a temperatura de ebulição da água. A temperatura voltou a aumentar, de forma mais gradual, após a perda de grande parte da umidade do colchão. Observa-se que colchões formados por flocos de maior espessura apresentaram elevação mais rápida de temperatura no miolo. O principal fator que influenciou na velocidade de elevação da temperatura no miolo dos painéis aglomerados foi o teor de umidade do colchão, sendo que quanto maior o teor de umidade, mais rápida foi a elevação da temperatura.

Abstract:

Subject area Innovation and creativity in small to medium-sized enterprises (SMEs) in Latin America. Study level/applicability The case is recommended for creativity and innovation subjects, in undergraduate and MBA levels. The case is also suggested for subjects associated with the organizational dynamics on SMEs. Case overview Colchones Eldorado is a Colombian company dedicated to the bedding industry. The company was founded in 1957 by Gumercindo Gómez Caro, a creative man who in 1959 invented a machine to make springs, which allowed the company to grow steadily for several decades. On November 18, 2004, the founder's daughter, Martha Luz Gomez, was appointed as General Manager. On April 2011 it obtained a license from Sealy, the biggest mattress making company in the USA. The license implied a challenge - testing the company's innovative capacities to adapt Sealy mattresses to satisfy consumers in the Colombian market. Expected learning outcomes Students are shown the characteristics of the creative and innovation process in a Latin American SME, and the innovation challenges which are faced. From the reading and the case discussion, the students should be able to: analyse the manifestations of the creative process in an SME; identify examples of the innovation types of an SME; and discuss the organizational conditions to answer the creativity and innovation challenges in an SME.

La presente investigación tiene como objetivo establecer la estructura de mercado de la industria de fabricación de colchones en el Ecuador y las relaciones que presentan las variables concentración, precios del mercado local, tipo de cambio y rentabilidad. Se utiliza un modelo de regresión de ecuaciones simultáneas de mínimos cuadrados en tres etapas (MC3E) con información de las empresas con mayor cuota de mercado del sector. La concentración de mercado se calcula utilizando el índice Herfindahl – Hirschman. Los principales resultados exhiben que existe una estructura de mercado imperfecta y que la cuota de mercado incide en la rentabilidad del oligopolio. El oligopolio a su vez no ejerce poder de mercado, por la competitividad en precios de los colchones importados.

Abstract:

Background Recent climatic history has strongly impacted plant populations, but little is known about its effect on microbes. Alders, which host few and specific symbionts, have high genetic diversity in glacial refugia. Here, we tested the prediction that communities of root symbionts survived in refugia with their host populations. We expected to detect endemic symbionts and a higher species richness in refugia as compared to recolonized areas. Methods We sampled ectomycorrhizal (EM) root tips and the nitrogen-fixing actinomycete Frankia communities in eight sites colonized by Alnus glutinosa subsp. barbata close to the Caucasus in Georgia. Three sites were located in the Colchis, one major Eurasian climatic refugia for Arcto-Tertiary flora and alders, and five sites were located in the recolonized zone. Endemic symbionts and plant ITS variants were detected by comparing sequences to published data from Europe and another Tertiary refugium, the Hyrcanian forest. Species richness and community structure were compared between sites from refugia and recolonized areas for each symbionts. Results For both symbionts, most MOTUs present in Georgia had been found previously elsewhere in Europe. Three endemic Frankia strains were detected in the Colchis vs two in the recolonized zone, and the five endemic EM fungi were detected only in the recolonized zone. Frankia species richness was higher in the Colchis while the contrary was observed for EM fungi. Moreover, the genetic diversity of one alder specialist Alnicola xanthophylla was particularly high in the recolonized zone. The EM communities occurring in the Colchis and the Hyrcanian forests shared closely related endemic species. Discussion The Colchis did not have the highest alpha diversity and more endemic species, suggesting that our hypothesis based on alder biogeography may not apply to alder’s symbionts. Our study in the Caucasus brings new clues to understand symbioses biogeography and their survival in Tertiary and ice-age refugia, and reveals that isolated host populations could be of interest for symbiont diversity conservation.

Abstract:

Los ácaros son microorganismos que se encuentran presentes en el polvo común de los hogares y que, en la mayoría de las ocasiones, generan enfermedades de origen respiratorio y dermatológico. Esto afecta significativamente la calidad de vida y hace que esta problemática sea de interés en salud pública veterinaria, debido a la posible relación de los ácaros con la tenencia de animales. El objetivo general de este trabajo fue determinar la cantidad de ácaros intradomiciliarios/gramos de polvo en noventa hogares de tres localidades de Bogotá (Ciudad Bolívar, Rafael Uribe Uribe y San Cristóbal). La metodología se basó en la recolección de muestras por medio de aspirados de colchones, almohadas y piso. Se trabajaron treinta hogares en las tres localidades mencionadas, para un total de noventa familias y 270 muestras de polvo. Los resultados por familia se condensaron en un formato establecido, en el cual se especificó la cantidad de ácaros por gramo de polvo obtenido. Posteriormente, los datos se analizaron con el uso de estadística descriptiva y medidas de tendencia central. Se encontró que la especie más determinante fue el Dermatophagoides pteronissynus con mayor porcentaje en almohadas (Ciudad Bolívar 71,32%, Rafael Uribe Uribe 69,66% y San Cristóbal 75%). Sin embargo, en colchones y piso también se evidenció una predominancia porcentual. Los mayores promedios de ácaros/gramo de polvo se encontraron en colchones de las localidades de Ciudad Bolívar (92,50) y San Cristóbal (617,49), mientras que en la de Rafael Uribe Uribe lo obtuvo el piso (36,59).

Abstract:

Greek mythology (myth about the Argonauts) have made character of Medea of Colchis the indivisible part of world cultural heritage. For centuries character of Medea has maintained its significance and comprised source of inspiration for the representatives of various spheres of fine arts.[1] Of course, regarding the contexts of the epochs (conceptual and esthetic position) and author’s intent, some motifs of the Argonauts’ myth and character of the woman of Colchis have been changing. In this respect, novel „Megi, Georgian Girl“ by Georgian modernist writer, Grigol Robakidze is of interest. Text, first published in 1932 in Germany[2] was translated into Georgian in 2012 and it is not properly studied till now.

Abstract:

For the first time the level of endemism in high-mountain flora of north-west edge of uplands of the Caucasus was estimated. A uniquely high level of endemism in Fisht-Oshten Massif and Chernomorskaya (Black Sea) Chain was observed: 28.4% (342 species) with predominance of Caucasian (9.2%), Pan Caucasian (7.4%) and West-Caucasian (5.1%) endemics. Colchis and North Colchis endemics total take 5.8%, and together with local endemics riches the third position. The level of endemism of alpine species is one of the highest in the Caucasus and is 43.2% (276 species). The levels of endemism revealed general trends, depending on the remoteness of local flora from the main diaspora on the Fisht-Oshten massif and the current area of the meadow belt. These trends are visible for endemics of all ranks, with the exception of the West Caucasian endemic, whose number is higher in the eastern part of Black Sea Chain and is falling sharply to the west part.

Abstract Two silver vessels: a silver aryballos from the mid-5th century BC burial No. 11/1969 in Vani and a silver goblet from the ritual complex No. 1 of the Ulyap barrow No. 1 in the Kuban basin, dated to the late 5th-early 4th century BC, are discussed. e similarities in details of the vessels and their decoration with those of the silver vessels found in Lydia and the vicinity of Sinope are pointed out. A group of items of toreutics from the 5th-4th centuries BC complexes in Colchis and outside it is singled out: they are decorated with incised animal or mythological images, the bodies of which are covered with vertical rows of horizontal notches. One can not exclude, that this kind of decoration goes back to the images on the Colchian bronze axes and belts of the 8th-6th centuries BC. The characteristic rosette decorating the bottoms of the vessels from Vani, Ulyap and the phiale No. 61 from the Treasure of Akhalgori is analysed; its genesis is discussed going back to the rosettes on the 6th century BC phialai from Iran, Asia Minor and the Balkans. Further the examples of Lydian metalware found in Colchis are discussed, including the phiale with the votive inscription to the temple of Apollo in Phasis found in the later Sarmatian burial in the Kuban basin. Finally, the problem of the 'international Achaemenid style' and the regional school of Achamenid-inspired toreutics is analysed. In general the author comes to the conclusion of the strong influence of toreutics of the Lydian-Ionian school and Anatolia in a broad sense of this term on the local school of toreutics, which emerged in Colchis in the 5th-4th centuries BC.

Abstract:

Abstract Sinopean imports ‐ coins, ceramic ware ‐ amphorae, mortars and tiles ‐ found in the south-western Georgian Black Sea littoral characterise different aspects of relationships in the south and eastern Black Sea littoral over a long period. The south-western coast of ancient Colchis seems to have been closely connected with Sinope from the fifth century BC. Sinopean finds become more and more frequent in fourth-third centuries BC contexts. From the last quarter of the fourth century BC, the leading role of trading with Colchis passed to Sinope. It was archaeologically expressed in the intensive circulation of Sinopean drachmas and hemidrachmas as well as in the import of Sinopean ceramic ware (amphorae, mortars, tiles) and production of their local imitations. In the Roman and early Byzantine periods, Sinope was a key base for the Roman army and fleet at the southern Black Sea coast. Finds of Sinopean ceramic products of this period are frequent during the excavations of the fortresses of the Roman and early Byzantine period on the eastern Black Sea littoral.

Abstract:

For the Argonauts of Valerius Flaccus the Black Sea and its surrounding lands are an alien world. As Argo leaves the Mediterranean behind and enters the Propontis, we are told that the Minyans begin to gain ‘a view into another world’ (alium prospectus in orbem, 2.628). So too when the ship makes its way through the Bosporus, on the point of entering the Black Sea, we are told that the Greeks ‘see all things new’ (noua cuncta uident, 4.424). Clearly this voyage is presented by Valerius as a major event in world history.One question which must confront any reader of Valerius’ poem is whether the effects of this voyage should be viewed negatively or positively. Indeed the poem itself poses that question at the outset, through its inclusion of two versions of Argo's destiny: the negative prophecy of Mopsus (1.211-26) and the more reassuring prediction of Idmon (1.234-38). In this paper I propose to consider aspects of this problem through an examination not of Valerius' treatment of the voyage itself, but of its consequences as they are presented in the second half of the poem.

Abstract:

The development of amphora production in Colchis is examined, from its beginnings in the mid-4th cent. BC under the influence of vessels from Sinope. The emergence of amphora production should be seen as the result of Hellenic influence upon the economy and upon craftsmen of the E littoral of the Black Sea. Throughout the Classical period one type of Colchian amphora existed, which underwent drastic change in the course of time. Three successive variants may be discerned. The earliest, from the mid-4th to 3rd cent. BC, retains similarities with the Sinopean prototypes. In the late 3rd and 2nd centuries BC, substantial changes in morphology and dimensions take place. In the late 1st and early 2nd centuries AD the third variant, with a rib under the rim, appears. Petrographic analysis shows that the vessels were made within one extensive region, Colchis, but at a variety of centres. They were produced in state-owned and private workshops, employing both Greek and local craftsmen. The Greek workshops (or those which had links with Greek potters) were the main exporters of amphorae to the northern Black Sea coastal region from the 4th cent, BC to 1st cent. AD.

Abstract:

The article collects the modest evidence available on the use (and possible production) of ceramic building material by the Roman army in Colchis, using it as a backdrop for presenting the exceptional richness, in quantity as much as diversity, of the finds from Gonio/Apsaros. The signatures on these products add to the value of this assemblage. Part 1 of the article presents documented examples of stamps on bricks, roof tiles and ceramic pipes from the Gonio/Apsaros fort and links them to the construction projects of specific Roman army units in the Cappadocia province. The results of laboratory tests conducted on samples of ceramic products and raw clay from Gonio, presented in Part 2, distinguish between two reference groups for the production of which clay from near the fort was used. However, it has not been possible to indicate the specific deposits of such raw material used by the Roman army.

There are 176 endemic plants spread in southern Colchis, of which 45 can be used for some medical treatments. The bioecology and detailed phytochemical content of some medicinal plant populations have not been studied so far. The research objectiveis to study the phytochemical content of endemic species of Helleborus caucasicus, Helleborus abchasicus and Ficaria popovii spread in southern Colchis. The research method for the phytochemical content included separation analysis, whichwas performed byusing UPLC-MS (Waters Acquity QDa detector). Three Steroidal glycosideswere isolated from the MeOH extract of the plants of Helleborus caucasicus and Helleborus abchasicus: Hellebrigenin-D-glucose, 20 – Hydroxyecdysone and Hydroxyecdysone – 3 glucoside. Two saponins (Hederagenin 3-O -α-L-arabino pyranoside, Hederagenin28-O-[α-L-rhamno-pyranosyl(1→4)-β-D-glucopyranosyl-(1→6)]β-D-lucopyranoside) and four flavonoids (kaempferol 3-O-β-ᴅ- (6ʺ-α-ʟ-rhamnopyranosyl)-glucopyranoside (nicotiflorin), apigenin 8-C-β-ᴅ-glucopyranoside (vitexin), luteolin 8-C-β-ᴅ-glucopyranoside (orientin), quercetin 3-O-rutinoside) were isolated from the tubers and flowers of Ficaria Popovii. Three Steroidal glycosides and Hydroxyecdysone -3 glucoside were isolated from the MeOH extract of Helleborus caucasicus.In addition, two saponins and four flavonoids were isolated from the tubers and leaves of FicariaPopovii.

Abstract:

Three associations of the class Carpino-Fagetea Jakucs et Passarge 1968 were described as а result of the classification of forest communities of the Colchis Lowland (Westem Transcaucasia) using the Brown Blanquet method. Association Vaccinio arctostaphilli-Carpinetum betuli ass. nova prov. was included in the order Lathyro-Carpinetalia Passarge 1981, alliance Crataego-Carpinion Passarge 1981. Associations Truello thunbergii-Alnetum barbatae ass. nova prov. and Carici remotae-Pterocmyetum pterocarpae ass. nova prov. were included in the order Rhododendro ponticae-Fagetalia orientalis Quezel et al. 1992, alliance Alnion barbatae Quezel et al. 1992. The results of the DCA ordination and the interpretation of the leading axes demonstrated three well-distinguished ecological and floristic types of deciduous forests (ofthe association rank) forming the ecological series according to the leading ecological factors - the degree of humidity of habitats and the degree of drainage of substrates. Twenty-three plant species - thermophilous Tertiary rehcs were found in all three associations. Of these, eight evergreen species play а significant phytocoenotic role in the formation of the understory in forest communities.The pecuharities of the Tertiary rehc speciesdistributions in the floristic compositions of described associations are discussed.
