Oxazole scaffold compounds currently find application in
medicinal drugs such as Aleglitazar (antidiabetic), Ditazole
(platelets aggregation inhibitor), Mubritinib (tyrosine kinase
inhibitor), and Oxaprozin (COX-2 inhibitor) (Kakkar et al.,
2018). In addition they show anti-microbial (Tomi et al., 2015)
and anti-cancer (Liu et al., 2009) activity.In this context, we
determined the crystal structure of the title compound

In this study, the inversion modeling method
variability of S-wave velocity structure results by
inverting/forward-modeling waveforms and HVSR
curves is investigated. For this purpose, eight KiK-net
seismic stations using 636 foreshocks, mainshock of the
2011 Tohoku earthquake, and 4983 aftershocks obtained from KiK-net are used. The most reliable and representative inverted S-wave velocity structures are based
on close fitting of the theoretical to the observed data of
waveforms and HVSR curves. The inverted S-wave
velocity structures derived from the total stress analyses
are showing high degrees of similarity and consistency
using both EW and NS components and evidenced by
the isotropic HVSRs directionality related to the linear
and nonlinear site effects. Conversely, stiffness variations due to nonlinearity, inferred from inverted S-wave
velocity structures derived from the diffuse field assumption, significantly correspond with stiffness variations evaluated from the observed fundamental resonance frequencies. The corresponding percent of reduction and recovery reflect low variability in S-wave velocities that result from inversion modeling based on
diffuse field assumption. Qualitatively, the presence of
the stiffness degradation process due to linear and nonlinear site responses could be obviously detected using
both inversion modeling methods based on total stress
analyses and diffuse field assumption. Quantitatively,
the precision of the nonlinearity evaluation is questionable due to significant uncertainties in the inverted Swave velocity structures inferred from both inversion
modeling methods. These uncertainties are strongly dependent on the theory of each inversion modeling method. The use of complementary methods with more prior
information is suggested to resolve the nonuniqueness
of the inverted S-wave velocities and hence overconfidence in the precision of the nonlinearity evaluation.

In the last decades were witnesses that hydrogen is in the limelight as an environmentally benign and alternative energy source to fossil fuels. The hydrolysis of sodium borohydride (NaBH4) is promising for the synthesis of materials/chemical compounds and on-demand hydrogen generation-based applications. Herein, cobalt embedded zeolitic imidazolate frameworks (Co@ZIF-8) were synthesized at ambient temperature via a one-pot method (within 60 ​min). X-ray diffraction (XRD) pattern ensures the successful synthesis of a pure phase of Co@ZIF-8 crystals. Transmission electron microscope (TEM) and nitrogen (N2) adsorption-desorption isotherm reveal that Co@ZIF-8 has a hierarchical porous structure. Co@ZIF-8 exhibited high catalytic activity for the hydrolysis of NaBH4 with a hydrogen generation rate (HGR) of 7230 ​mL•gcat−1•min−1 (18 ​× ​106 ​mL•gCo−1•min−1). The high catalytic performance and the simple synthesis procedure of Co@ZIF-8 endow the material’s high potential to be a catalyst for hydrogen generation via the hydrolysis of hydrides such as NaBH4.

Wadi El Assiuti represents a promising area for agricultural development and building new communities far from the overpopulated areas in the Nile Val-ley. An integrated approach of satellite-based data and geophysical data with borehole data was used for defining the area of interest, the sediment thick-ness, delineating the subsurface structures, and mapping the depth to the basement rocks, and defining the groundwater aquifers. Findings are: 1) Dramatic changes are detected in the anthropogenic activities at the entrance area of the wadi, making stress and heavy exploitation of the groundwater resources. However, the central and northeastern regions show no development; 2) Several structural trends in the directions of NNW, NW, NE, and E-W are cutting the basement rocks and sedimentary cover; 3) The depth to the basement rocks is increasing eastward from ~2.24 km to ~4.84 km; 4) Three groundwater-bearing reservoirs are represented by the shallow Qua-ternary, the fractured limestone, and the deep Nubian sandstone aquifers; 5) The deep-seated faults are affecting the area and rising groundwater from the deeper Nubian aquifer along its sub-vertical trend; and 6) The results are in-formative and used to define the suitable sites for water well drilling.

The Middle East is suffering from water scarcity in the arid/semiarid settings. The recent advance of technologies in the geophysical fields made groundwater monitoring possible from space. Time-variable gravity data and climatic model are utilized to monitor mass variations caused by groundwater changes over the Sinai Peninsula during the period 04/2002-07/2016. Results are: (1) Sinai Peninsula is receiving low average annual precipitation (AAP) rate, varying from 22.3 mm/yr to 68.5 mm/yr; (2) The average annual Terrestrial Water Storage variations (ΔTWS) were estimated at -3.92 ± 0.23 mm/yr; (3) The average yearly non-groundwater components were estimated at -1.35 ± 0.032 mm/yr; (4) The average annual groundwater
storage variations (ΔGWS) were estimated at -2.57 ± 0.22 mm/yr. The depletion in the mass variations over Sinai seems to be caused by the natural discharge, low rainfall rates, and the surface runoff from the land
toward the water bodies. The integrated approach is informative and a replicable study for the areas of poor information.

We report a neutronics study of a blanket mock-up using a discharge-type compact fusion neutron source. Deuterium–deuterium fusion neutrons were irradiated to the mock-ups composed of tritium breeder and neutron reflector/moderator. Tritium production rate (TPR) per source neutron was measured by a single-crystal diamond detector (SDD) with a 6Li-enriched lithium fluoride film convertor after the calibration process. Despite the low neutron yield, energetic alpha and triton particles via 6Li(n,t)α neutron capture as well as 12C via elastic scattering were successfully detected by the SDD with high signal to noise ratios. The TPRs were experimentally evaluated with errors of 8.4–8.5% at the 1σ level at position A to D, in which the errors were dominantly introduced by uncertainties in the monitoring of the neutron production rate. The calculated to experimental (C/E) values of TPR were evaluated to be 0.91–1.27 (FENDL-2.1) and 0.94–1.28 (FENDL-3.1). As the neutron source can generate 14 MeV neutrons using a mixed gas of deuterium and tritium, this approach provides more opportunities for blanket neutronics experiments.

An inertial electrostatic confinement (IEC) fusion device accelerates ions, such as deuterium (D) or tritium (T), to produce nuclear fusion and generate neutrons. The IEC's straightforward configuration consists of a concentric spherical transparent cathode at a negative bias surrounded by a grounded spherical anode. The effects of cathode properties on the neutron production rate (NPR) remain, to date, inadequately studied. This study aims to determine the impact of the cathode material on the NPR by investigating fusion reactions on the cathode surface. Two buckyball-shaped cathodes made of stainless steel (SS) and titanium (Ti), both of 5 cm diameter, fabricated by selective laser melting and 3D printing, are used for this investigation. A SS spherical chamber of 25 cm inner diameter is used as an anode in this experiment. A performance evaluation of surface fusion reaction in the IEC using SS and Ti grids is
