Eugenia roxburghii is an evergreen graceful shrub with a tremendous potential as garden plant. As a part of ex-situ conservation and popularization of the species, seed longevity was studied by understanding the relationship of seed viability with respect to different moisture contents and storage temperature. Seeds are recognized as recalcitrant, being desiccation as well as chilling sensitive. During hermetic storage, seeds stored at 300C/70%RH retained viability for about 5 months and 4 months in 200C/20% RH. Seeds can be best stored for five months in laboratory conditions.

Seeds of Garcinia talbotii remained viable hardly for two weeks in open room conditions. As part of ex-situ conservation of Garcinia talbotii, seeds longevity was studied since seeds are the main propagule. For this, the relationship of seed viability with respect to different moisture content and storage temperature were analyzed. Seed storage behaviour is also investigated. Being recalcitrant, seeds are desiccation sensitive as well as chilling sensitive. During hermetic storage of seeds at 300C /70 % RH seeds retained viability about 6 months.

Glass fiber–halloysite nanotube (GF/HNT) nanocomposites were fabricated with different numbers of fiber layers and were exposed to a high-temperature water environment to analyze the role of the HNTs regarding the relationship of interface between the fibers and the moisture absorption behavior. The sections of the GF/HNT nanocomposite plates were divided, and the change in the moisture absorption rate was measured. As a result, the ratio of the HNT to epoxy resin was not related to the water deterioration phenomenon according to the fiber-laminated thickness. However, in the curing process after the vacuum bag molding, the external pressure that was applied to each interface influences the flow characteristics and promotes the occurrence of HNT agglomeration, which interferes with interfacial crosslinking.

Abstract Oil palm produces the most consumed vegetable oil in the world. In addition to being economically viable and having multiple uses, the crop has a strong ecological appeal, given its high level of carbon sequestration, its low environmental impact, and a low mechanization level in the harvest process, generating income and financial sustainability for the inhabitants of that biome. However, despite the large areas suitable for cultivation in harmony with the forest in Brazil, oil palm production has been limited by a disease known as fatal Yellowing (FY). In 30 years of research to determine the causal agent of this disease, many epidemiology studies with insects and plant pathogens have been performed, but there is no consensus on its cause. Abiotic factors have also started to be considered a possible cause of these symptoms. Therefore, to clarify the relationship of this disease to environmental variables, we studied the nutritional status of the plant, the soil class and fertility, the climatic variables and attempted to verify the set of proteins and their isoforms expressed in diseased palms showing FY symptoms and healthy palms. FY occurred under constant rain and in clay soils; consequently, the roots of these palm trees suffered anoxia, which caused nutritional problems and the accumulation of stress-related proteins. Under these conditions, the usually observed symptom was yellowing, which can lead to the death of the plant, giving the disease its name. In other words, the symptomatic picture is not associated with only a biotic cause. Thus, a pedological survey of the area, planting in soils not subject to waterlogging or with good drainage conditions, and the correct maintenance of soil fertility and plant nutrition may certainly contribute to the management of and reduction in fatal yellowing without the use of agrochemicals.

The article shows the relationship of the yield of four promising forms of peach with its most limiting factors. The equations of multiple regression are also presented, which allow us to predict the yield of the studied forms. In form Veteran free pollination the coefficient of multiple regression was R = 0.95, the coefficient of multiple determination was R2 = 0.90; in the hybrid form Zlatogor x Uspar-1 80-367, respectively, 0.99 and 0.98; in the form Lauréat x Zlatogor 73-3 - 0.96 and 0.92; the form (Podarok Kryma free pollination x Tovarishch) 85-104 - 0.98 and 0.96. These coefficients show the degree of dependence between productivity and factors included in the study. Selected hybrid forms should be used in breeding for adaptability to improve the existing assortment of peach. The hybrid form Veteran free pollination was transferred to the State Commission of the Russian Federation, as a cultivar Sarabuz, which is of interest for breeding and production as a promising table cultivar with fruits of medium ripening time.

The present research features the relationship between the two processes in design. First, more and more areas of culture reveal their design character. Second, design activity is getting more and more innovative. This is due to the increasing attention to design in science and practice, in particular, in cultural studies. This relationship is interpreted as a separate subject of research, which has the following constituents: a) cultural conditions and factors, b) the process of implementation of technical and technological innovations in the socio-cultural fabric of society and man. Thus, there is a problem of their mutual determination, which can be investigated by such methods of analysis as idealization and modeling. Creativity is represented as one of the manifestations of culture as a whole and is expressed in the conceptual vision of design and continuity of socio-cultural design. The authors focus on the matter of socio-cultural support and effective implementation and assimilation technical and technological innovations by culture, society, and man by creating certain conditions and factors. The concept of the design configurator is used here as a model of the process represented in the problem. The paper enumerates the functional features of management objectivity, pragmatism, efficiency, creativity, heuristics, etc., which make it possible to focus on methodological approaches not only in problem solving but also to argue the importance of the design approach in the understanding of the relationship of these socio-cultural sides of human existence. The design configurator is not only a synthesis of different types of subject knowledge, but rather a starting point in the methodological work on the formation of epistemological portrait of the created artifact, i.e. technological innovations using such methodological tools as socio-cultural and design approach.

The Penicillium luteum — P. purpurogenum group of species of Penicillium described by Thom (1915), contains a number of species and strains, with a strain of P. luteum Zukal, at the one end of the series and P. purpurogenum Stoll, at the other end. The strain of P. luteum Zukal, which occupies one end of this series, “ produces ascospores freely in all the media used and conidia very sparingly. In the actively growing culture the dominant shades of colour are yellow with tardy appearance of red.” P. purpurogenum Stoll, at the other end of the series, “ produces only conidia, in which yellow shows transiently while red colours in mycelium and substratum are abundant.” “ The production of yellow in the surface growth at some period of colony development or under some cultural conditions is typical for the group. This may be dominant, transient, or almost lacking, yet it is not difficult to demonstrate in the organisms studied. Coincident with the change of colour in the surface or aerial growth we find at the luteum end of the series that yellow to orange shades predominate in the substratum. These slowly or but partially change to red as the colonies become old. In the forms producing conidia only, yellow or orange tones still appear in the young colony. The change to red is slow and only partial in some forms, but towards the purpurogenum end of the series the yellow colours are reduced to but transient appearances, replaced quickly and almost completely by red.” (The quotations are from Thom’s paper quoted above.)

Pendugaan kelimpahan ikan terumbu secara akustik masih jarang dilakukan karena tingginya keanekaragaman jenis dalam suatu agregasi sehingga sulit membedakan nilai hambur balik akustik tiap jenis ikan. Oleh karena itu penelitian ini dilakukan dengan tujuan menganalisis hubungan kepadatan ikan Abudefduf saxatilis, Scolopsis lineatus dan Chaetodon trifasciatus terhadap perubahan nilai volume backscattering strength (Sv) kemudian menganalisis tingkat kesesuaian pendugaan kepadatan ikan secara akustik dengan kepadatan ikan sebenarnya melalui pengukuran secara ex situ. Metode yang digunakan adalah metode kurungan untuk pengukuran akustik secara ex situ. Alat yang digunakan dalam pengukuran akustik adalah Echosounder Simrad EK-15 frekuensi 200 kHz. Hasil penelitian menunjukkan nilai hambur balik akustik ketiga ikan terumbu memiliki hubungan yang sangat tinggi dengan kepadatan ikan. Peningkatan kepadatan ikan ikan terumbu akan meningkatkan nilai hambur balik akustik secara linier. Pendugaan kepadatan ikan secara akustik menunjukkan bahwa ikan Abudefduf saxatilis dan ikan Scolopsis lineatus menghasilkan dugaan kepadatan ikan yang sama secara statistik dengan kepadatan ikan yang sebenarnya, sedangkan ikan Chaetodon trifasciatus menghasilkan dugaan kepadatan ikan yang berbeda dan cenderung lebih kecil dari kepadatan ikan yang sebenarnya.MEASUREMENT OF REEF FISH DENSITY USING EX SITU ACOUSTIC METHODS. Estimation of reef fish abundance using acoustic method is still rarely done. High diversity of species in an aggregation impacts on the difficult to distinguish the backscatter value for each species. Therefore, this research was proposed to analyze the relationship of fish density of Abudefduf saxatilis, Scolopsis lineatus and Chaetodon trifasciatus for the changing of volume backscattering strength value, then to analyze the conformity of estimate coral fish density comparing with actual reef fish density through ex situ acoustical measurements. Cage method was used in this research for ex situ acoustical measurement using Echosounder Simirad EK-15 200 kHz. The result showed that the acoustic backscattering value of three species had a high relationship with fish density. The density of Abudefduf saxatilis and Scolopsis Lineatus were statistically similar to the actual fish density, while the density of Chaetodon trifasciatus was different and tend smaller than the actual fish density.

Biologic Factors

The Mesozoic-Cenozoic coral Order Scleractinia has been suggested to have originated or evolved (1) by direct descent from the Paleozoic Order Rugosa or (2) by the development of a skeleton in members of one of the anemone groups that probably have existed throughout Phanerozoic time. In spite of much work on the subject, advocates of the direct descent hypothesis have failed to find convincing evidence of this relationship. Critical points are:(1) Rugosan septal insertion is serial; Scleractinian insertion is cyclic; no intermediate stages have been demonstrated. Apparent intermediates are Scleractinia having bilateral cyclic insertion or teratological Rugosa.(2) There is convincing evidence that the skeletons of many Rugosa were calcitic and none are known to be or to have been aragonitic. In contrast, the skeletons of all living Scleractinia are aragonitic and there is evidence that fossil Scleractinia were aragonitic also. The mineralogic difference is almost certainly due to intrinsic biologic factors.(3) No early Triassic corals of either group are known. This fact is not compelling (by itself) but is important in connection with points 1 and 2, because, given direct descent, both changes took place during this only stage in the history of the two groups in which there are no known corals.

Insight Into

Echinodermata is a phylum of marine invertebrates which has been extant since Cambrian time (c.a. 500 m.y. before the present). Modern examples of echinoderms include sea urchins, sea stars, and sea lilies (crinoids). The endoskeletons of echinoderms are composed of plates or ossicles (Fig. 1) which are with few exceptions, porous, single crystals of high-magnesian calcite. Despite their single crystal nature, fracture surfaces do not exhibit the near-perfect {10.4} cleavage characteristic of inorganic calcite. This paradoxical mix of biogenic and inorganic features has prompted much recent work on echinoderm skeletal crystallography. Furthermore, fossil echinoderm hard parts comprise a volumetrically significant portion of some marine limestones sequences. The ultrastructural and microchemical characterization of modern skeletal material should lend insight into: 1). The nature of the biogenic processes involved, for example, the relationship of Mg heterogeneity to morphological and structural features in modern echinoderm material, and 2). The nature of the diagenetic changes undergone by their ancient, fossilized counterparts. In this study, high resolution TEM (HRTEM), high voltage TEM (HVTEM), and STEM microanalysis are used to characterize tha ultrastructural and microchemical composition of skeletal elements of the modern crinoid Neocrinus blakei.
