Results of the laboratory study of the quality of gentian seed are analyzed in this paper. Seed originated from wild and grown plants from Zlatibor Mountain (approx. 1000 m above sea level) collected in the third decade of August 2006 and from wild and grown gentian plants around Ivanjica (approx. 1030 m above sea level) collected also in the third decade of August 2006, as well as from grown plants in the Tara Mountain (approx. 1000 m above sea level) collected during the same period. The effects of cooling (90 days at 40C) and moistening and cooling (90 days at 40C) on germination energy (GE) and total germination of seed (TG) were observed. The origin of the seed (if it comes from grown or wild plant) had influence on both investigated traits, and grown seed had slightly better germination energy and higher total germination compared to seed of wild plants. On the location in Tara we had no seed from wild plants so no comparison was possible. The location also demonstrated significant effect on traits of ability for living, so wild seed from Zlatibor was of higher quality than the one collected in the vicinity of Ivanjica. In regard to seed from grown gentian the highest quality was determined in seed grown in Zlatibor Mountain, than Tara, and the poorest germination traits were exhibited by seed grown around Ivanjica. The variant with moistening and cooling of seed regardless of the location and origin possessed better germination energy and total germination compared to seed that has only been cooled, and especially in regard to the control (no cooling). .

The aim of the research presented in this paper is the experimental confirmation of the numerically defined shapes of the Strut-and-Tie models, designed according to the EN 1992-1-1 recommendations, and obtained from the software “ST method”. Three reinforced concrete deep beams with openings were tested. Each of them had the same dimensions and quality of the material characteristics. The specimens, constructed as simply supported beams, were loaded with two concentrated forces and were tested for bending until failure. Each specimen was reinforced with different reinforcement layout determined by variation parameter β, incorporated in the software “ST method”. For the determination of the Strut-and-Tie models, all of the reinforcement layouts were equally favored in the first specimen (β = 1.0 for 0°, 45°, and 90°), only the horizontal direction was favored in the second (β = 1.0 for 0°), while in the third specimen the one at the angle of 45° (β = 1.0 for 45°). Based on the results of experimental research, it was concluded that the behavior of loaded members was in agreement with the proposed shapes of the Strut-and-Tie models that were used for their design, and it was confirmed that the program “ST method” can be used for obtaining Strut–and-Tie models.

After more than 10 years in orbit, the SMOS team has started a new reprocessing campaign for the SMOS measurements, which includes the changes in calibration and image reconstruction that have been made to the Level 1 Operational Processor (L1OP) during the past few years. The current L1 processor, version v620, was used for the second mission reprocessing in 2014. The new version, v724, is the one run in the third mission reprocessing and will become the new operational processor. The present paper explains the major changes applied and analyses the quality of the data with different metrics. The results have been obtained with numerous individual tests that have confirmed the benefits of the evolutions and an end-to-end processing campaign involving three years of data used to assess the improvements of the SMOS measurements quantitatively.

Abstract Introduction                 Medical doctor competency exams (UKMPPD) in Indonesia is a final test that should be followed by medical student before being declared worthy of a medical doctor’s degree. This exam is certainly intended with good intentions, in order to improve the standards and quality of graduates of Indonesian doctors. However, each policy turns out to have two opposite sides of the situation, on the one hand it is profitable but on the other it often creates new problems. Students’ fear of the competency test often causes new psychological problems for students. No doubt the failure of the competency exam causes students to experience prolonged disappointment and sadness, which in turn will cause depression. This research is the first research that aim to present a description of personality and psychopathology dimension data from UKMPPD participants who failed the test.   Method This study was an exploratory descriptive study by presenting narratives of personality and psychopathology dimensions of unsuccessful UKMPPD participants. This research was conducted at the Faculty of Medicine, Universitas Sriwijaya Palembang, Indonesia. Each participant was assessed personality and psychopathology dimensions using MMPI-2 (Minnesota Multiaxial Personality Inventory-2). The results of analysis with MMPI-2 present data in the form of clinical psychic conditions, the work capacity, interpersonal relationships, the work abilities and the ability to change the self  potential of the research subjects.   Result The research subjects were UKMPPD participants who did not successfully pass the first exam. From 7 research subjects, there were 2 subjects who successfully passed the second exam (28.5%) and there were 3 people who successfully passed after the third exam (43%). Meanwhile, 2 research subjects have not successfully passed the UKMPPD exam until the fifth exam (28.5%). The results are quite surprising that of the 7 participants who failed to pass the UKMPPD exam, all of them felt depression.   Conclusion Medical students who experienced UKMPPD failures have an inability to develop their own potential which result in depression due to failure of the exam

In Sonora, Mexico, a new crop is emerging as a potential and alternative crop industry: the bacanora plant (Agave angustifolia Haw). The bacanora plant belongs to the Amaryllidaceous family and is a type of agave with a low water requirements, growing as a wild plant in Sonora, Mexico. It is different from the one used to produce the most famous Mexican liquor in the world—tequila. Some time ago, the bacanora plant had been used to distill and produce a kind of liquor known by Sonoran people as bacanora. However, this activity was prohibited by the Sonoran government during the past century. Now, in order to encourage job growth, the Sonoran government has given permission to producers for new bacanora plantations. To protect the originality of both bacanora plant production and the bacanora distillation industry, the Federal Mexican government issued a law that prohibits all activity for growing bacanora plant and bacanora distillation outside of Sonora, Mexico. The law was approved in 2005 and now, all natural areas where wild plants of bacanora grow are known as “origin denomination,” which means that some Sonoran areas are unique locations where the bacanora industry can be legally established for plant production, distillation, refining, and labeling. Currently, there are about 20,000 ha of bacanora plants located in Sonora. Some producers estimate that, in the near future, there will be more than 60,000 ha of bacanora plants. Although bacanora plants are used mainly for producing liquor, they could be considered ornamental plants for establishing home desert gardens together with desert plants, such as cacti.

The range of food stuffs having a rich composition of useful substances can be greatly enhanced by using a great variety of wild plants growing in Siberia. Apart from familiar widely used wild mushrooms, berries and other wild plants a biennial herbage plant, namely, great burdock can be used. Precise requirements to safety of wild plants growing in Russia are not available in regulatory documents. This makes it much more difficult to pass the procedures of confirming the conformity of products. This also has a negative effect on the processes of harvesting, storage, processing and transportation of wild plant raw materials. The key goal of testing the quality of products is to ensure safety of food stuffs. This goal can be achieved by further study of wild plants and by establishing precise standards of safety.

Резиме: Организација трезорског система доста је сложена с обзиром на многобројне функције које се обављају у оквиру трезора. Извршење једне од тих функција подразумијева и евидентирање трансакција у вези са прикупљањем и трошењем буџетских средстава што свакако има посљедице и на финансијске извјештаје буџетских корисника. Предмет овог рада је управо сагледавање утицаја трезорског система на финансијске извјештаје. На основу података прикупљених техником анкетног упитника и на основу метода анализе, индукције и дедукције на примјеру Републике Српске дошло се до резултата који показују да је увођење трезорског система олакшало доношење одлука и повећало квалитет финансијског извјештавања у јавном сектору, али да би превазилажењем техничких недостатака који тренутно постоје ефекти били још већи. У прва два дијела рада пружа се теоријски преглед основа финансијског извјештавања у јавном сектору и трезорског система пословања, док је у трећем дијелу приказана методологија истраживања и резултати до којих се дошло истраживањем.Summary: The organization of the treasury system is quite complex due to the fact that many functions performed within the treasury system. The execution of the one of these functions involves recording transactions relating to the collection and spending budget funds, which certainly will affect the financial statements of budget users. The subject of the paper is a consideration of the treasury system impact on the financial statements. Based on the data collected using the questionnaire technique and based on the methods of analysis, induction and deduction on the example of the Republic of Srpska, we came to the result that indicates the treasury system facilitate decision-making and in the same time increase the quality of financial reporting in the public sector, but if overcome technical deficiencies that currently exist, effects will be even greater. The first two parts of the paper provides an overview of the theoretical basis of financial reporting in the public sector and the treasury system, while the third section presents the methodology and the results obtained during research.

The effects of incorporating full-fat soy flour (FFSF) into milk replacers on growth, mortality and meat quality of lambs were determined. In the first two experiments, the FFSF supplied 24 and 30%, respectively, of the total protein (N × 6.25), and was compared with all-milk protein (AMP) formulas. Refrigerated milk replacers at 20% (w/w) solids were fed ad libitum from nipples and a teat bar. Half the lambs on each liquid diet received only milk replacer to slaughter at 18 kg liveweight; the other half were weaned at 11 kg, and then received solid feed. The FFSF milk replacers had no significant effects on lamb weight gains or carcass evaluation (dressing per cent, fat cover and color scores, tenderness and flavor) when compared with lambs fed the AMP formulas. Meat from lambs fed only milk replacer lacked distinct lamb flavor. In the third experiment three milk replacers containing AMP or 50% of the protein from FFSF were compared: AMP (30% fat air-dry basis), FFSF (30 and 40% fat). The reconstituted milk replacers were fed twice daily at 37 ± 2 C. Liveweight gains of lambs to weaning at 4 wk old were less on the FFSF formula containing 40% fat than on the one with 30% fat. However, gains to slaughter at 41 kg were not significantly affected. Carcass data from lambs fed the three milk replacers were similar, except for increased tenderness in those fed the 40% fat formula. It was concluded that FFSF could satisfactorily supply 50% of the total protein in lamb milk replacers fed twice daily provided abomasal bloat could be prevented.

Miscanthus is a promising high-yielding and low-input perennial biomass crop. However, as miscanthus does not produce nectar, it provides less support for pollinators than other perennial biomass crops, such as cup plant, Virginia mallow, or wild plant mixtures. This study discusses whether miscanthus could be intercropped with flower-rich biennial wild plants to further enhance its ecological functioning. In 2017, a demonstration plot was established in southwest Germany with two miscanthus intercropping regimes: woad (WAM) and yellow melilot (YAM). Both woad and melilot reached full bloom in 2018, the second year of cultivation. The flowering period of woad started and ended earlier than that of melilot. Woad remained harvestable until spring 2019, whereas the aboveground melilot was destroyed by brown hare in autumn 2018. However, the shed seeds of melilot reemerged homogeneously in 2019. The miscanthus developed better in YAM than WAM. This was most likely due to (i) stronger competition for water, nutrients, and light in WAM and (ii) nitrogen fixation advantage in melilot. These results indicate that the ecological performance of miscanthus could be improved by intercropping with melilot. Thus, we propose to further investigate the effects of intercropping on both the productivity and quality of miscanthus biomass.

The first question to be answered, in seeking coordinate systems for geodynamics, is: what is geodynamics? The answer is, of course, that geodynamics is that part of geophysics which is concerned with movements of the Earth, as opposed to geostatics which is the physics of the stationary Earth. But as far as we know, there is no stationary Earth – epur sic monere. So geodynamics is actually coextensive with geophysics, and coordinate systems suitable for the one should be suitable for the other. At the present time, there are not many coordinate systems, if any, that can be identified with a static Earth. Certainly the only coordinate of aeronomic (atmospheric) interest is the height, and this is usually either as geodynamic height or as pressure. In oceanology, the most important coordinate is depth, and this, like heights in the atmosphere, is expressed as metric depth from mean sea level, as geodynamic depth, or as pressure. Only for the earth do we find “static” systems in use, ana even here there is real question as to whether the systems are dynamic or static. So it would seem that our answer to the question, of what kind, of coordinate systems are we seeking, must be that we are looking for the same systems as are used in geophysics, and these systems are dynamic in nature already – that is, their definition involvestime.

The article discusses the future of mobility in the light of energy resources. Fossil fuel will not be available for a long time - not to mention its growing environmental and political conflicts. In analysing the potential of biofuel it is argued that the high demands of modern mobility can hardly be fulfilled in the future. Furthermore, the change into using biofuel will probably lead to increasing conflicts between the fuel market and the food market, as well as to conflicts with regional agricultural networks in the third world. Petrol imperialism might be replaced by bio imperialism. Therefore, mobility on a solar base pursues a double strategy of raising efficiency on the one hand and strongly reducing mobility itself on the other.
