Effect of azotobacter products on lettuce transplants

While the nutrient supply in conventional farming is mainly provided by fertilizers, the organic farmers have to use nutrient-rich organic materials to produce seedlings of high quality. The advantage of transplants use in the vegetable growing can be to realize earliness (it gives higher benefit), increase growth safety, etc. Effect of bacteria (like microbial agent) can transform faster the nutrients from organic material. It can give opportunity for organic manure to affect faster in the substrate. The aim of this research was to determine: growing lettuce seedling only with the use of organic materials, estimating the effectiveness of some microbial products in vegetable transplant growing, and effect of microbial products on efficiency of manures. The results show that the combination of organic fertilizers and soil bacteria has effect on the increasing of nitrogen up-take of plants

A hypothermia élettani hatásai = Physiologic effects of hypothermia

A normálistól eltérő, alacsonyabb testhőmérséklet, hypothermia terápiás alkalmazása az elmúlt évtizedben újra előtérbe került a neurológiai károsodás megelőzése, kialakulása esetén, illetve mértékének csökkentése érdekében. Használata nemcsak a szív- és idegsebészetben, hanem számos más, idegrendszeri sérüléssel vagy annak magas kockázatával járó folyamatban jótékony hatásúnak bizonyult. Jelenlegi ismereteink szerint ez az egyetlen olyan terápiás eszköz, amely az újraélesztésen átesett betegek neurológiai kimenetelét bizonyítottan javítja egy komplex folyamat révén, csökkentve az agy oxigénfelhasználásának és -ellátásának arányát. Jótékony hatása mellett számos olyan élettani és kórélettani hatással rendelkezik, amelyek pontos ismerete elengedhetetlen, hiszen ezek akár életet veszélyeztető állapotot is eredményezhetnek. Mindezek miatt nagyon fontos, hogy a terápiás hypothermiát csak olyan szakemberek használják, akik pontosan ismerik annak hatásait, és felkészültek a káros mellékhatások megelőzésére, illetve kivédésére. Írásunkban a hypothermia különféle szervekre, szervrendszerekre kifejtett élettani hatásait foglaljuk össze. Orv. Hetil., 2011, 152, 171–181. | Therapeutic use of hypothermia has come to the frontline in the past decade again in the prevention and in mitigation of neurologic impairment. The application of hypothermia is considered as a successful therapeutic measure not just in neuro- or cardiac surgery, but also in states causing brain injury or damage. According to our present knowledge this is the only proven therapeutic tool, which improves the neurologic outcome after cardiac arrest, decreasing the oxygen demand of the brain. Besides influencing the nervous system, hypothermia influences the function of the whole organ system. Beside its beneficial effects, it has many side-effects, which may be harmful to the patient. Before using it for a therapeutic purpose, it is very important to be familiar with the physiology and complications of hypothermia, to know, how to prevent and treat its side-effects. The purpose of this article is to summarize the physiologic and pathophysiologic effects of hypothermia. Orv. Hetil., 2011, 152, 171–181

Wind-snow interactions at the Ojos del Salado region as a potential Mars analogue site in the Altiplano - Atacama desert region

The general characteristics and interactions happening at a unique, potential new Mars analogue site, located in the Altiplano and Atacama Desert region: the Ojos del Salado inactive volcano. The interaction between rare snowing events and strong winds transported large masses of porous volcanic grains there could produce decimeter - meter thick buried snow masses fast, shielded against sublimation for extended periods (years). Subsurface temperature logging suggests that water ice melting is rare and surface modification is dominated by desiccation of the cryosphere and wind activity – just like on Mars. The site contains decameter scale megaripples, which are unusual for Earth and also support the understanding of resemble features on Mars. The shallow subsurface analysis with Mars relevance is supported here by drilled cores of evaporitic sediments

Analysis of surface morphology of basaltic grains as environmental indicators for Mars

Analysing the microtextures of grains from different sediments helps to determine their transport medium. This method is well developed in the case of quartz grains, because quartz is usually dominant in sediments on Earth. In this study, basaltic sands from aeolian and fluvial environments from Iceland and from the Azores Islands were analysed, since basaltic rocks have been found on Mars, and paleo-environment reconstruction is an important goal of future missions. Fixed grains were imaged and analysed by a high-resolution electron microscope. Several different surface identification marks were found corresponding to known examples from quartz micromorphologies: conchoidal fractures, steps, and percussion marks, which are connected to fluvial environments; while precipitation features and bulbous edges were identified and connected to the aeolian transport. In these generally very diverse samples some new micromorphologies, which have not previously been found on quartz grains, were also identified. The identification of such features which are not present on quartz is expected, as the sample has a different composition than quartz. These newly identified features were named as: fan-shaped percussion marks; isometric shaped grains with a rough surface (fluvial); “large voids” with abraded surface and cracked surface (aeolian). Based on our results, a further improved version of the method evaluating grain surface micro-morphology could be useful not only for quartz grains, but in the case of the basaltic grains too. Such information could help to identify the settling environments of grains on Mars, we therefore also discuss the spatial resolution and observational conditions required to do so by in-situ Mars missions there. We conclude that a one order of magnitude increase in the spatial resolution (down to about 1 μm) would greatly support the identification of grain surface features and interpretation of transport methods. This level of resolution is not far beyond that which is currently available

Formation and shock impact history of the Csatalja ordinary chondrite

The analysis of the Csatalja H4 chondrite (which was found in August 2012) suggests shock-related textures and spatial inhomogeneities, indicating a complex geological history. In the most heavily fractured and sheared units, small opaque grains and older fractures have locally enhanced the shock effect, producing melt. While the impact textures were evident in most units of the meteorite, mechanical shearing is apparent in only two units, suggesting that these units might have been present at somewhat different locations inside the parent body. Shearing also occurred at the border of the so-called xenolith unit, confirming its mechanical mixing with the other units. Besides fragmentation and melting, chemical changes due to impact have also been identified, producing compositional homogenization of olivines in 30% of the investigated area of the sample’s thin section (23 mm2), and moderate accumulation of Fe, Ca, and Na in the strongly shocked zones, initiating crystallization of feldspar in veins with a specific spatial distribution (feldspar glass with metal–sulfide globules). Analyzing the high P–T minerals, the peak shock pressure and temperature values differed substantially in the various units, ranging between 2 and 17 GPa, 100 and >1200 °C
