Изучение существ – создателей важнейшего компонента жизни на планете – почвы, скорее всего, важная часть подготовки межпланетных космических команд. Работа представляет собой многоплановое исследование, где главным объектом выступает насекомое – Палочник аннамский. Автором проведены наблюдения за пищевой активностью и получены данные о количестве помета, то есть скорости формирования будущего гумуса. Проведено выращивание комнатного растения хлорофитум и оценено влияние смеси песка и гуано палочника на рост листьев и корней. Автору удалось провести серию химических анализов на количество нитратов в полученной «почве». Оценка концентрации нитратов в грунте проводилась как с помощью реагентов, так и с использованием прибора «Соэкс Эковизор F4». С их помощью получены данные о разных по времени формирования «почвах». The study of the creatures - creators of the most important component of life on the planet - the soil, first of all, is an important part of the preparation of interplanetary space teams. The work is a multifaceted study, where the main object is the insect – the Annam stick insect. The author carried out observations of food activity and obtained data on the amount of litter, that is, the rate of formation of future humus. A chlorophytum houseplant was grown and the effect of a mixture of sand and stick insect guano on the growth of leaves and roots was evaluated. The author managed to conduct a series of chemical analyses for the amount of nitrates in the resulting "soil". The assessment of the nitrate concentration in the soil was carried out both with the help of reagents and with the use of the device "Soex Ecovisor F4". With their help, data on "soils" of different formation times were obtained.

Alcohol Production

The problems caused by the residual effluents of wine distilleries for alcohol production are well known. The effluent effects in soil and groundwater are being researched in an area with sugar cane culture which receives; yearly, vinasse by dispersion. Samples are being collected from the soil, the groundwater and the existing creeks in the area Four sub-areas are being monitored separately with a vinasse application of 300 m3/ha year. Experimentation periods in each area have been 0, 5, 10 and 15 years. In the unsaturated zone, samples are being collected at depths of 25, 75 and 150 cm. The chemical analyses include macro and micro nutrients, organic matter and pH. Physical analyses give the soil water retention, hydraulic conductivity and soil particle distribuition. These measurements permit the evatution of nitrogen absorption and fertility changes of the soil. A tendency for the maintenance of soil fertility can be observed but with an elevation of nitrate concentration in groundwater.

AbstractIt is suggested that the outbursts of Periodic Comet Schwassmann-Wachmann 1 are triggered by impacts of interplanetary boulders on the surface of the comet’s nucleus. The existence of a cloud of such boulders in interplanetary space was predicted by Harwit (1967). We have used the hypothesis to calculate the characteristics of the outbursts – such as their mean rate, optically important dimensions of ejected debris, expansion velocity of the ejecta, maximum diameter of the expanding cloud before it fades out, and the magnitude of the accompanying orbital impulse – and found them reasonably consistent with observations, if the solid constituent of the comet is assumed in the form of a porous matrix of lowstrength meteoric material. A Monte Carlo method was applied to simulate the distributions of impacts, their directions and impact velocities.

Radio Event

The type II solar radio bursts produced by a shock wave passing through the solar corona are one of the most frequently studied solar activity phenomena. The scientific interest in this type of phenomenon is due to the fact that the presence of this radio event in a solar flare is an almost certain indicator of a future geophysical effect. The origin of the shock waves which produce these bursts is not at all simple; besides the shocks which are generated as a result of a strong energy release during the impulsive phase of a flare, there are also the shocks generated by a coronal mass ejection or the shocks which appear in the interplanetary space due to the supplementary acceleration of the solar particles.

Solar Filaments

AbstractSolar filaments are discussed in terms of two contrasting paradigms. The standard paradigm is that filaments are formed by condensation of coronal plasma into magnetic fields that are twisted or dimpled as a consequence of motions of the fields’ sources in the photosphere. According to a new paradigm, filaments form in rising, twisted flux ropes and are a necessary intermediate stage in the transfer to interplanetary space of dynamo-generated magnetic flux. It is argued that the accumulation of magnetic helicity in filaments and their coronal surroundings leads to filament eruptions and coronal mass ejections. These ejections relieve the Sun of the flux generated by the dynamo and make way for the flux of the next cycle.

Swietenia Mahagoni

Swietenia mahagoni is a timber forestry plants have allelopathy toxic, can interfere with the growth of surrounding plants. This study aimed to determine the effects of extracts from various parts of Swietenia mahagoni on seed germination of green beans and corn. This research was conducted at the Laboratory of Silviculture, an extract from a litter, fresh leaves, bark and roots of the Swietenia mahagoni plant and given to the seed germination green beans and corn. The results showed that the extract of fresh leaves and roots Swietenia mahagoni inhibit seed germination green beans and corn, while the provision of litter no effect. Green bean seed has a higher durability of the maize seed to allelopathy of root Swietenia mahagoni.
