Effects of liquid pig manure fertilization on the density and species structure of Oribatida (Acari) and green forage yield in a lowland meadow in PolandThe effect of liquid pig manure fertilization, with or without the disinfectant VIT-TRA, on oribatid communities was investigated in a lowland meadow in Poland. The disinfectant was tested at 3 concentrations: 0.50% (fungicidal), 0.75% (bactericidal), and 3.00% (viricidal). Liquid pig manure without the disinfectant increased the green forage yield along with increasing doses of this fertilizer, while addition of disinfectants affected the yield in different ways. Low and medium doses of fertilizer (20 and 40 m3·ha-1) with fungicide slightly decreased the yield, while the high dose (60 m3·ha-1) usually increased it, as compared to the control. Low and medium doses of liquid pig manure, treated or not with disinfectants, decreased the abundance of oribatid mites. In contrast, the high dose increased their abundance, except for the plot with a high dose of viricide, where they were slightly less abundant than in the control. In the investigated meadow,Liebstadia humerata, Parachipteria bellaandScheloribates laevigatuswere abundant, but reacted negatively to low and medium doses of liquid pig manure treated or not with disinfectants, and positively only to the high dose of fertilizer treated with fungicide and bactericide, as compared to the control plot.

The Impact

AbstractWe investigated the impact of pig or goat manure fertilization of a meadow with doses of 80 kg N ha−1, 140 kg N ha−1, and 200 kg N ha−1(plots 1-6) on oribatid mites. A control plot (0) was left unfertilized. The manure was applied to the meadow in the early spring of 2012, and soil samples were collected in the spring of 2012 and 2013. In total, 6053 oribatid mites were examined, including 1163 juveniles. The effect of fertilizing on the Oribatida depended on the dose of manure, but not on its type. A low dose of pig or goat manure did not affect the density of Oribatida, whereas the other doses decreased it, but only the highest doses decreased it significantly, compared to the control. Species diversity decreased with the dose of manure. In total, 24 species of Oribatida were found and some species reacted differently to both types of manure. For example, a low dose of pig manure significantly increased the density ofEupelops occultus, whereas the density of other species significantly decreased under the influence of the highest dose of pig manure (Achipteria coleoptrata), highest doses of pig and goat manure (Galumna obvia,Liebstadia similis), and medium and highest doses of goat manure (Scheloribates laevigatus).

Salt Affected Soil

Increasing soil carbon storage and biomass utilization is an effective process for mitigating global warming. Coal bio-briquettes (CBB) are made using two low-ranked coals with high sulfur content, corn stalks, and calcium hydroxide, and the combustion ash can ameliorate the physicochemical properties in salt-affected soil. CBB ash contains mainly calcium compounds, such as calcium sulfate, calcium hydroxide, and calcium carbonate, and coal fly ash and biomass ash. In this paper, changes in soil carbon and nitrogen content through salt-affected soil amelioration during 5 months using two CBB ashes and pig manure were examined in Northeast China. Application rates of CBB ash were 0 tha−1 (control), 11.6 tha−1, 23.2 tha−1, 46.4 tha−1, and 69.6 tha−1. Consequently, total carbon content in topsoil (0–0.15 m) after harvest of maize in all test fields indicated a range between 27.7 tCha−1 and 50.2 tCha−1, and showed increased levels compared to untreated salt-affected soil. In a 3.0% (69.6 tha−1) application plot of only CBB ash with higher carbon and higher exchangeable Ca2+, the carbon content increased by 51.5% compared to control plot, and changes in carbon sequestration compared to untreated soil was roughly twice that of the control plot. CBB ash contributed to carbon application and pig manure supply as a form of N fertilization in the case of all test plots. Changes in carbon content due to soil amelioration have a significant relationship with changes in corn production and soil chemical properties, such as pH, Na+, Cl−, sodium adsorption ratio (SAR), and exchangeable sodium percentage (ESP). Therefore, CBB production from low-ranked coal and waste biomass, and the use of CBB ash in agriculture is advocated as an effective means for sequestering carbon.

Effect of cattle liquid manure fertilization on the yield of grassland and density of soil oribatid mites (Acari, Oribatida) The effect of cattle liquid manure without and with Effective Microorganisms (EM) on the hay yield and density of soil Oribatida was investigated in a lowland meadow. Fertilization of the meadow with low and medium doses (30 m3·ha-1 and 60 m3·ha-1) of liquid manure increased the hay yield, more with EM than without them. However, the highest dose (90 m3·ha-1) of fertilizer did not change hay yield, as compared to the control plot. All doses of cattle liquid manure reduced the density of oribatid mites, distinctly more without EM than with them. This suggests a favourable influence of EM on these mites. Among the Oribatida, Liebstadia similis, Scheloribates laevigatus, Eupelops occultus, and Achipteria coleoptrata, were abundant, while other species were infrequent. The community of Oribatida was dominated by adults.

Effect of cattle liquid manure fertilization and disinfectant on seasonal dynamics of Oribatida (Acari) in a permanent lowland meadow in Poland Oribatid mites have a favourable influence on soil fertility. The effect of cattle liquid manure fertilization (40 and 80 m3 ha-1) and disinfectant at 3 concentrations: 0.50% (fungicidal), 0.75% (bactericidal), and 3.00% (viricidal) on seasonal dynamics of Oribatida was investigated in a permanent lowland meadow in Poland. Cattle liquid manure without disinfectants reduced the density of oribatid mites, especially in the spring, except for a higher dose of fertilizer in the summer, which increased their density compared to the control plot. This fertilizer treated with the disinfectants differentiated the density of oribatid mites, i.e. reduced or increased it, compared to the control plots. However an increased density was observed only in summer, after application of the higher dose of fertilizer with fungicide or viricide. In the control plot, some species (Achipteria coleoptrata and Parachipteria bella) were rather abundant in the spring and autumn, and some other species (Liebstadia humerata and Scheloribates laevigatus) only in the spring. Cattle liquid manure and disinfectants changed the dynamics of density of these species. In the control plot the adults were slightly more abundant than the juveniles in the spring, but the juveniles dominated in the summer, and the adults dominated again in the autumn. Cattle liquid manure and disinfectants changed the age structure of oribatid mites. None of the experimental variants was favourable for Oribatida in all seasons.

Abstract The features of the structure of the population of oribatid mites (Oribatida) as primary destructors of dead plant material that provide such ecosystem service as improvement of soil fertility are considered. Studies were performed in various stratigraphic types of artifi cial edaphotopes in the reclaimed sites of “Pavlogradskaya” query (Pavlograd, Dnipropetrovsk Region, Ukraine), which were planted with eastern red cedar (Juniperus virginiana Linnaeus). Th e amount of oribatid mite species in the forest litter of studied forest plantation varied from 16 to 25. Minimal number of species (16) and minimal population density of oribatid mites (4720 ind./m2) was established for calcic chernozem topsoil type with sand interlayer, which can be explained by lower thickness of the forest fl oor litter within this reclamation type.

Beam Damage

Over the past five years it has become evident that radiation damage provides the fundamental limit to the study of blomolecular structure by electron microscopy. In some special cases structural determinations at very low doses can be achieved through superposition techniques to study periodic (Unwin & Henderson, 1975) and nonperiodic (Saxton & Frank, 1977) specimens. In addition, protection methods such as glucose embedding (Unwin & Henderson, 1975) and maintenance of specimen hydration at low temperatures (Taylor & Glaeser, 1976) have also shown promise. Despite these successes, the basic nature of radiation damage in the electron microscope is far from clear. In general we cannot predict exactly how different structures will behave during electron Irradiation at high dose rates. Moreover, with the rapid rise of analytical electron microscopy over the last few years, nvicroscopists are becoming concerned with questions of compositional as well as structural integrity. It is important to measure changes in elemental composition arising from atom migration in or loss from the specimen as a result of electron bombardment.

Diffraction studies in polymeric and other beam sensitive materials may bring to mind the many experiments where diffracted intensity has been used as a measure of the electron dose required to destroy fine structure in the TEM. But this paper is concerned with a range of cases where the diffraction pattern itself contains the important information.In the first case, electron diffraction from paraffins, degraded polyethylene and polyethylene single crystals, all the samples are highly ordered, and their crystallographic structure is well known. The diffraction patterns fade on irradiation and may also change considerably in a-spacing, increasing the unit cell volume on irradiation. The effect is large and continuous far C94H190 paraffin and for PE, while for shorter chains to C 28H58 the change is less, levelling off at high dose, Fig.l. It is also found that the change in a-spacing increases at higher dose rates and at higher irradiation temperatures.

Melanin Complex

Two benzofuran derivatives, chlorpromazine and amiodarone, are known to produce inclusion bodies in human tissues. Prolonged high dose chlorpromazine therapy causes hyperpigmentation of the skin with electron-dense inclusion bodies present in dermal histiocytes and endothelial cells ultrastructurally. The nature of the deposits is not known although a drug-melanin complex has been hypothesized. Amiodarone may also cause cutaneous hyperpigmentation and lamellar lysosomal inclusion bodies have been demonstrated within the cells of multiple organ systems. These lamellar bodies are believed to be the product of an amiodarone-induced phospholipid storage disorder. We performed transmission electron microscopy (TEM) and energy dispersive x-ray microanalysis (EDXA) on tissue samples from patients treated with these drugs, attempting to detect the sulfur atom of chlorpromazine and the iodine atom of amiodarone within their respective inclusion bodies.A skin biopsy from a patient with hyperpigmentation due to prolonged chlorpromazine therapy was fixed in 4% glutaraldehyde and processed without osmium tetroxide or en bloc uranyl acetate for Epon embedding.

Exposure to drugs and toxic chemicals, during late pregnancy, is a common occurrence in childbearing women. Some studies have reported that more than 90% of pregnant women use at least 1 prescription; of this, 60% used more than one. Another study indicated that 80% of the consumed drugs were not prescribed, and of this figure, 95% were “over-the-counter” drugs. Acetaminophen, the safest of all over-the-counter drugs, has been reported to induce fetal liver necrosis in man and animals and to have abortifacient and embryocidal action in mice. This study examines the degree to which acetaminophen affects the neonatal liver and kidney, when a fatty diet is simultaneously fed to the mother during late pregnancy.Timed Swiss Webster female mice were gavaged during late pregnancy (days 16-19) with fat suspended acetaminophen at a high dose, HD = 84.50 mg/kg, and a low dose, LD = 42.25 mg/kg; a control group received fat alone.

Oxygen Ion Implantation

The formation of buried oxide structures in single crystal silicon by high-dose oxygen ion implantation has received considerable attention recently for applications in advanced electronic device fabrication. This process is performed in a vacuum, and under the proper implantation conditions results in a silicon-on-insulator (SOI) structure with a top single crystal silicon layer on an amorphous silicon dioxide layer. The top Si layer has the same orientation as the silicon substrate. The quality of the outermost portion of the Si top layer is important in device fabrication since it either can be used directly to build devices, or epitaxial Si may be grown on this layer. Therefore, careful characterization of the results of the ion implantation process is essential.
