First Results

At current work we present first results of comparative study of the morphology and chemical composition in biomineral particles (phytoliths) of different types of wheat (Volzhskaya, Moskovskaya 39, Primorskaya 40). Optical microscopy reveals 5 morphotypes of phytolith in the stem and spike of wheat Triticum aestivum L. Although, only 3 morphotypes of phytolites were found in all three varieties, and the other 2 morphotypes were found only in some cases. These differences may be sort-specific signs. Various phytoliths have different linear sizes. As demosntrated, even within a sole type of wheat, there appears variability of the phytolitic composition. This fact may have significant implication for practical use of the phytolith analysis.

Winter Wheat Varieties

In the trade of the European Union principally the analysis of alveographical and extensographical parameters mean the acceptance system.In the present study we analysed the extensographical parameters of 10 winter wheat varieties breed by the Cereal Research Non Profit Company with Brabender extensigraph and we made a comparison, correlation among the results. The examinations with Brabender the following among: show the GK Kalász and the GK Élet varieties show high resistance of extension and the GK Petur variety produces high extensibility. The GK Garaboly has shown low extensibility and energy. The other parameters had different values in the examined three years. The measurings with SMS2 Texture Analyser show middle positive correlation between extensibility and subarea. There are weak correlation between at the significantial level in the 90, 135 resistence of extension by Brabender and by SMS2 Texture Analyser and in the 45 extensibility by Brabender and by SMS2 Texture Analyser of relaxed dough. There is no correlation among other parameters.

In the present study, the chemical composition of water extracts of Chinese and Vietnamese cassia (Cinnamomum cassia) were compared using multivariate analysis of LC-MS data. By principal component analysis of the LC-MS data, 6 compounds, cinnzeylanine (1), cinnzeylanol (2), anhydrocinnzeylanol (3), cinncasinol A (4), epicatechin (5) and procyanidin B2 (6), were identified as the marker compounds to characterize Chinese and Vietnamese cassia. It was clarified that Chinese cassia contains relatively larger amounts of epicatechin and procyanidin B2. On the other hand, Vietnamese cassia is characterized by a relatively larger amount of diterpenes. As catechin derivatives and diterpenes have different types of activity, it is important to choose the cassia that best suits the product for which it is to be used, whether in food or in herbal medicine.

Two locally grown ancient wheat varieties named Carosella and Majorca (Triticum aestivum L.) were studied for their phytochemical contents and biological activities. Four different types of flour obtained from each variety were investigated. Carosella and Majorca samples showed high concentration of polyphenol content and high antioxidant activity. Among the different types of flour obtained by different grindings (whole wheat, 2, 1, and 0), whole wheat showed the highest antioxidant activity expressed as inhibition of DPPH radical, with an IC50 value of 0.008 mg/mL for Carosella and 0.011 mg/mL for Majorca. The total polyphenol content ranged from 11.72 to 14.34 g/kg in Carosella samples and from 11.96 to 13.67 g/kg in Majorca samples. The results of this study reveal that the two wheat varieties, Carosella and Majorca, could be considered potential sources of antioxidant agent and could play a major role in human health.

This presentation introduces the current work of the Bioimage Corsortium and its international collaborators in the setting up of a new data base containing volumes of biological specimens.The scope of the data that we will be organizing during the next three years is very broad, ranging from macromolecules to larger structures or even entire cells. The approach is designed to combine the desire to break many undesired formal barriers between the type of volume information produced at the different resolution levels whith, at the same time, the clear need of implementational flexibility required to appropriately handle different types of data.The internal organization of the Bioimage Consortium clearly reflects the objectives presented above. In the first place, partners in the consortium have the scientific knowledge and projection in areas ranging from macromolecular structure to cell dynamics. These partners are then nucleated around two well-defined “servers”, one in Madrid, responsible for the work on macromolecular structures, and the other in Heildeberg, responsible for data more in the area of cell biology.

A field experiment was carried out in Dar-ul-Aman Research Farm, Kabul Afghanistan in 2017, to study the influence of sowing dates and varieties on the biological yield of wheat crop (Triticum aestivum L.). The experiment was laid out in RCBD with a split-plot arrangement having three replications. Wheat was sown in different sowing dates i.e., October 24th, November 2nd, 12th, and 22nd in main plots, whereas five wheat varieties (Chounth # 1-2010, Moqawim-09, Shisham Bagh-08, Dar-ul-Aman-07 and Solh 2002) were in sub plots. November 2nd planted wheat had a highest biological yield of (6642.1 kg ha-1) followed by October 24th and November 12th which gave (6576.5) and (5711.0 kg ha-1) respectively. The lowest biological yield of (2975.1 kg ha-1) was given by the wheat varieties sown on November 22nd. Among the all-wheat varieties, Solh 2002, had significantly higher biological yield of (6263.7 kg ha-1) followed by Shisham Bagh-08 with biological yield of (5571.8 kg ha-1). However, Moqawim-09 had lowest biological yield of (4976.8 kg ha-1) compare to other varieties. While, evaluating performance of different wheat varieties on different sowing dates, Solh 2002, resulted in maximum biological yield (7476.2 kg ha-1) on November 2nd followed by Dar-ul-Aman-07 (6933.3 kg ha-1) and Shisham Bagh-08 (6860.0 kg ha-1) on November 2nd and October 24th respectively. On the other hand, Dar-ul-Aman-07 had lowest biological yield among the varieties (2015.5 kg ha-1) on November 22nd, it shows that, Dar-ul-Aman-07 had highest biological yield on early planting but lower yield on late sowing dates. The study shows that delay in wheat planting or selection of other varieties rather than Solh 2002 and Dar-ul-Aman-07 reduces the biological yield of the crop.

The Offset Dykes are impact melt-bearing dykes related to the 1.85 Ga Sudbury impact structure. Currently, the dykes extend radially outward from—or occur concentrically around—the Sudbury Igneous Complex, which is the remnant of a differentiated impact melt sheet and the source of the dykes. The recently identified three Pele Offset Dykes intrude into the Archean rocks north of the Sudbury Igneous Complex. In this study, the Pele dykes are characterized for the first time by a combination of fieldwork, optical microscopy, electron microprobe analyses, and bulk geochemical analyses. The Pele Offset Dykes stand out from the other Offset Dykes at Sudbury in two significant ways: (i) All other known Offset Dykes consist of an inclusion-rich lithology in the center of the dyke and an inclusion-poor lithology along the margins. The Pele dykes, however, are only composed of the inclusion-poor phase. (ii) The Pele dykes—particularly the Central and Eastern dykes—have a more evolved chemical composition relative to the other Offset Dykes. These observations suggest that the Pele dykes were emplaced after the other known Offset Dykes during two injection events: the Western followed by the Central and Eastern Pele dykes.

 This study aimed to assess the chemical composition of the forage and pre-dried silage from twelve winter cereals harvested at pre-flowering. We used black oat (Avena strigosa) cv. EMB 139 and cv. IAPAR 61; white oat (Avena sativa) cv. IPR and 126 hp. URS Taura; barley (Hordeum vulgare) cv. BRS Brau and cv. BRS Cauê; wheat (Triticum aestivum) cv. BRS Umbu and cv. BRS Tarumã; rye (Secale cereale) cv. Temprano and cv. BRS Serrano; and triticale (X. Triticosecale) cv. IPR and 111 hp. BRS Saturno. Plants were harvested at pre-flowering, when they were pre-dried and ensiled. The analysis of variance evidenced nutritional differences between species and cultivars. Triticale cv. IPR 111 showed notorious chemical characteristics in relation to the other treatments, highest protein content (113.7 g kg-1) and lower content of NDF and ADF (657.9 and 380.9 g kg-1, respectively). Among the pre-dried silages, barley cv. BRS Cauê had the highest level of NDT (614.7 g kg-1). Triticale cv. IPR 111 was shown as a high-quality nutritional food as forage and kept these characteristics after conservation. On the other hand, the pre-dried silage of barley cv. BRS Cauê showed the highest potential for nutrient degradability.

Dense precipitation of various intermetallic compounds is a common feature in the microstructure of Al-Si piston alloys. In this investigation, microstructure of LM13 alloy and three high Cu-containing Al-Si piston alloys with different amounts of Ni, Fe, and Mn were studied by means of optical microscopy (OM) and scanning electron microscopy (SEM). Chemical composition of the phases was determined by using energy dispersive X-ray analysis (EDX). The precipitation of the phases was studied through thermal analysis of the solidifying samples. Also, tensile properties and hardness of the samples were measured. The results showed that the various intermetallics such as Al12(FeMn)3Si2, Al3Ni, Al9FeNi, and Al3CuNi precipitated during the solidification. The high Cu-containing alloy with optimum levels of Ni (1.8 wt.%), Fe (0.75 wt.%), and Mn (0.3 wt.%) has the highest tensile strength (250 MPa) and hardness (110 BHN) among the other alloys.

My talk will be on the oblique rotator model which was first proposed by Stibbs (1950), and since received success and further developments. I shall present two different attempts at describing a star according to this model and the first results obtained in the framework of a Russian-French collaboration in order to test the precision of the two methods. The aim is to give the best possible representation of the element distributions on the Ap stellar surfaces. The first method is the mathematical formulation proposed by Deutsch (1958-1970) and applied by Deutsch (1958) to HD 125248, by Pyper (1969) to α2CVn and by Mégessier (1975) to 108 Aqr. The other one was proposed by Khokhlova (1974) and used by her group.

SummarySephadex gel filtration of human plasma gave results suggesting the presence of two proactivators of plasminogen, termed proactivators A and B.Activity resembling that of proactivator A was found in rabbit plasma, but not in guinea pig plasma.Plasminogen activators produced by the interaction of proactivator A of human plasma with streptokinase had no caseinolytic or TAMe esterolytic effect.Proactivator A can be separated in a form apparently free from plasminogen, as shown by the heated fibrin plate test and by immunological analysis. On the other hand, proactivator B concentrates prepared so far are contamined with plasminogen.Human proactivators appear to be far more susceptible to streptokinase than are rabbit proactivators.Inhibitors of the fibrinolysin system were observed in the plasmas of all 3 species. These inhibitors are not present in the euglobulin fraction of plasma. Sephadex fractionation of euglobulin fractions results in proactivator preparations that do not contain inhibitors.
