The study aimed to assess the effect-combined use different of date palm composts amended with ligno-cellulolytic fungi and mineral-N on growth and N, P and K-uptake of maize plants in sandy calcareous soil. Each type of compost was applied either in organic form in dose equivalent to 100% of N fertilization (285 kg ha-1) or in organic form in combination with mineral-N (50% for each). The experiment was constructed in a complete randomized block design (CRBD). Results showed that plant height and dry weight of shoot and root of maize significantly increased as a result of the combined use of compost with mineral-N (1:1, w:w). All types of composts combined with half-dose of mineral-N was effective, however, compost that contained with Aspergillus niger + A. subsessilis + Trichoderma lanuginosus + Bacillus sp. was the best. This type of fertilization increased N-uptake shoot and root of maize more than mineral N-fertilizer by 39.73%-49%. Inaddition, the P-uptake by shoot and root of maize increased by 58.82%-156%. The addition of compost treatments to the soil increased the total N, P and K after harvesting. Regression analysis showed positive and significant linear correlation between the application rate of compost and the availability of P and K in soil.

The performance of LaBr3(Ce) to measure nuclear resonance fluorescence (NRF) excitations is discussed in terms of limits of detection and in comparison with high-purity germanium (HPGe) detectors near the 2 MeV region where many NRF excitation levels from special nuclear materials are located. The NRF experiment was performed at the High Intensity γ-ray Source (HIγS) facility. The incident γ-rays, of 2.12 MeV energy, hit a B4C target to excite the 11B nuclei to the first excitation level. The statistical-sensitive non-linear peak clipping (SNIP) algorithm was implemented to eliminate the background and enhance the limits of detection for the spectra measured with LaBr3(Ce). Both detection and determination limits were deduced from the experimental data.

Production of electron bunches with extremely small transverse emittance is the focus of the PITZ (Photo Injector Test facility at DESY in Zeuthen) scientific program. PITZ is one of the leading laboratories on generation and optimization of high brightness electron bunches with different charges for free electron laser (FEL) machines such as FLASH and the European XFEL. In 2011 using a photocathode laser with a flattop temporal profile, PITZ has revealed record low transverse properties emittance values at different bunch charges. However, further improvement of beam quality with smaller emittance is foreseen using a cathode laser system, capable of producing 3D ellipsoidal bunches. Numerical simulations were performed to study and compare the beam dynamics of electron beams produced with 3D ellipsoidal and flattop laser profiles. Different bunch charges from 20 pC up to 4 nC are considered in the simulation, in order to find an optimum PITZ machine setup which yields the lowest transverse emittance. In the present paper, the simulation setup, conditions, and results of the comparison are presented and discussed.

Linac-based X-ray free electron lasers (XFELs) are the fourth generation light sources consisting of an injector, a linac section including RF linearizer and magnetic bunch compressor and an undulator section for the production of FEL radiation caused by the interaction of an electron beam and an electromagnetic radiation field produced by the beam itself. The flexible use of XFEL radiation is based on variable focusing and tuning the X-ray energy. These methods allow one to change the power density of the incident X-rays by many orders of magnitude. Due to the unique futures of XFEL radiation like short intense pulses, fields of high amplitude, frequency, and coherence, it has wide range of applications in variety of research fields, Chemistry, Biology, Medicine, and ets,. XFEL principles, light properties and applications will be reviewed in the conference.
