The long-range particles emitted during the spontaneous fission of $^{252}\mathrm{Cf}$ have been investigated, confirming emission $^{1}\mathrm{H}$, $^{2}\mathrm{H}$, $^{3}\mathrm{H}$, $^{3}\mathrm{He}$, $^{4}\mathrm{He}$, and $^{6}\mathrm{He}$. In addition it was found that $^{8}\mathrm{He}$, $^{6}\mathrm{Li}$, $^{7}\mathrm{Li}$, $^{8}\mathrm{Li}$, $^{9}\mathrm{Li}$, $^{9}\mathrm{Be}$, $^{10}\mathrm{Be}$, probably other isotopes Be are also emitted.

The quality of soil organic matter plays a central role in structure, carbon sequestration and pollutant immobilization. effect 16–23 years fertilization on the was studied field experiments at ten experimental sites Central Europe. Soil samples were collected 2016 after barley harvest. Six crops rotated: pea–canola–winter wheat–spring barley–beet/potato–spring barley. treatments studied: unfertilized control, mineral (NPK), farmyard manure, manure + NPK, straw incorporation, incorporation...
In long-term stationary experiments under different soil-climatic conditions, an influence of mineral and organic fertilization on yield winter wheat, spring barley potato tubers was evaluated. Statistically significantly lowest grain yields wheat (4.00 t/ha) (2.81 were obtained in non-fertilized plots at all experimental sites. the case potatoes, dry matter (5.71 recorded control plot, but result not statistically significant. The manure-fertilized plot gave average higher by 30%, 22%....

The influence of different mineral and organic fertiliser applications on the soil matter (SOM) content quality was monitored in long-term field trials. We used experiments (27 years) with a crop rotation potatoes, winter wheat, spring barley cambisol soil. treatments were as follows: an unfertilised control (Cont), sewage sludge normal triple doses (SS1 SS3, respectively), farmyard manure (F1) conventional dose, half dose nitrogen (F1/2 + N1/2), straw (N St), without any (N). This study...
The soil organic matter (SOM) content and quality are the fundamentals of fertility contribute significantly to carbon sequestration. glomalin is increasingly recognized as an indicator SOM quality. objective this study was evaluate capability contribution easily extractable (EEG), total (TG) content, potential wettability index (PWI) aggregates, water stability aggregates (WSA) instrumental indicators long-term changes. obtained results on EEG, TG, PWI, WSA were compared humic substances...

The changes of soil pH in long-term 14-year field experiments with different fertilizing systems are described. were located at four sites the Czech Republic and climatic conditions (Červený Újezd, Hněvčeves, Lukavec, Prague-Suchdol). At each site, same crop rotation (potatoes - winter wheat spring barley) established. Six experimental treatments applied to rotation: (1) unfertilized (control); organic fertilization: (2) farmyard manure (FYM), (3) sewage sludge (SS); mineral fertilizers: (4)...
Background The FiGARO (FFR versus iFR in Assessment of Hemodynamic Lesion Significance, and an Explanation Their Discrepancies) trial is a prospective registry searching for predictors fractional flow reserve/instantaneous wave‐free ratio (FFR/iFR) discrepancy. Methods Results FFR/iFR were analyzed using Verrata wire, coronary reserve was Combomap machine (both Philips‐Volcano). risk polymorphisms endothelial nitric oxide synthase heme oxygenase‐1 analyzed.

Triton and $^{3}\mathrm{He}$ energy spectra angular distributions from 43.7-MeV-proton bombardment of $^{9}\mathrm{Be}$ $^{7}\mathrm{Li}$ have been obtained. The restrictions on direct ($p, t$) reactions as compared to ($p$, $^{3}\mathrm{He}$) may result in the absence certain transitions for former because these are "$S$ forbidden"; several examples this selection rule were observed. Though lowest $T=\frac{3}{2}$ states mass-7 product nuclei readily observed, a search mass 5 was unsuccessful.
A field experiment was conducted on a chernozem soil to estimate fertiliser N efficiency of silage maize (Zea mays L.) by the difference method as influenced type (mineral-MF vs. sewage sludge-SS), and rate. Eight treatments were included (0, 60, 120, 180, 240 kg N/ha prior sowing, 60 at planting in MF; SS. The average dry mater (DM) yields 11.2-14.8 t/ha. Average nitrogen uptakes 88-185 N/ha, when contents DM 0.8-1.25%. Nitrogen utilization (NUE) relatively stable value for with MF. best...
The influence of different fertilizers (mineral/organic) on the quantity and quality soil organic matter was monitored in long-term stationary experiments (27 years) with silage maize monoculture production Luvisol. main aim this study to investigate relationship between easily extractable glomalin (EEG), total (TG), parameters commonly used for determination quality, i.e., content humic acids (CHA), fulvic (CFA), potential wettability index (PWI). A significant correlation found EEG CSOM...
Although fertilization and crop rotation practices are commonly used worldwide in agriculture to maximize yields, their long-term effect on the structures of soil microorganisms is still poorly understood. This study investigated impact microbial diversity community structure four different locations with three types. Since 1996, manure (MF; 330 kg N/ha), sewage sludge (SF; SF3x; 990 NPK (NPK; N/ha) fertilizers were periodically applied soils classified as chernozem, luvisol cambisol, which...

Studies of low-yield nuclear reactions such as (He3, He6) or (He4, He8) require definite identification about one interesting particle in the presence 106 to 107 reaction product particles. Conventional ΔE-E identifier systems are limited value these experiments a small fraction abundant particles produce ΔE signals which deviate considerably from their normal value. The resulting false cause general background output spectrum interferes with peak due In improved two detectors employed; each...
