The Role of Husamuddin Sadr Shahid and Husamuddin Al-Ahsikati's Scientific Heritage in Islamic Jurisprudence
The scientific heritage of two great Central Asian scholars, Husamuddin Sadr Shahid and Husamuddin al-Akhsikati, is of great importance to the Islamic Jurisprudence. An in-depth study of the scientific and spiritual heritage left by the faqihs of the Oli Moza family from Bukhara is one of the important tasks facing researchers today. This paper will detail the works and scientific heritage of Husamuddin Sadr Shahid (473/1090–536/1141), a great representative of the Ali Moza family and one of the famous Hanafi jurists, and his contemporary fellow, Husamuddin al-Akhsikati
The impact of salt concentration on the mineral nutrition of Tetragonia tetragonioides
The purpose of the experiment was to study the e ect of salinity (NaCl) on growth, biomass
production (total yield), mineral composition (macro- and micronutrient contents in leaves and
the soil in which the plant is grown) of Tetragonia tetragonioides during the vegetation period. The
experimental work was conducted in the greenhouse at the University of Lille 1, France, from 2
November 2015 to 25 January 2016. Three salinity treatments (T1 (50 mM NaCl), T2 (100 mM NaCl),
T3 (200 mM NaCl)) and a control treatment (T0 (0 mM NaCl)) were applied. Analysis of the results
showed that the total yield of the crop had low variation between the salinity treatments and the
control treatment. The salt concentrations had an e ect on the macro- and micronutrient contents in
leaves and soil. In conclusion, T. tetragonioides exhibited good potential for use as a species to remove
salt. This is the main important finding of this research.Erasmus Mundus Euro-Asian CEA project for support of the European

Effects of salinity on the Macro- and Micronutrient contents of a Halophytic Plant Species (Portulaca oleracea L.)
The main purpose of the two consecutive experimental studies presented here was to
compare the effect of salinity on nutrients in leaves of the halophytic plant species Portulaca oleracea L.
and in soil. The first experiment was conducted to study the effect of salinity on plant growth, biomass
accumulation, yield, root layer development, salt accumulation, and the dynamics of changes in
mineral substances in plants and soil. In the second experiment, P. oleracea seeds were sown directly
into salinized soil (treated immediately before plant growth) to determine the nutrient levels in leaves
and soil. Three salinity treatments (saline water solution with NaCl: T1, 5 dS m−1
; T2, 9.8 dS m−1
;
and T3, 20 dS m−1
) and a control treatment (T0, 1 dS m−1
) were used in the first experiment. The soil
in the second experiment was used in a previous study (performed immediately before P. oleracea
growth) (salinized soil: T1, 7.2 dS m−1
; T2, 8.8 dS m−1
; T3, 15.6 dS m−1
; T0, 1.9 dS m−1
). The plants
were irrigated with tap water at amounts in the range of 0.25–0.50 L/pot. Analysis of the experimental
results showed that P. oleracea is resistant to salinity, is able to remove ions (400–500 kg ha−1 NaCl),
and can be grown in saline soil. The results indicated that P. oleracea is able to grow in high-salinity
soil. This finding was confirmed by the dry matter obtained under high-salinity conditions. Salinity
stress affected nutrient uptake in leaves and soil.Erasmus Mundus European Joint Doctorate Programinfo:eu-repo/semantics/publishedVersio
Effect of irrigation water regimes on yield of Tetragonia tetragonioides
The main purpose of this experiment was to study the effect of several irrigation water regimes on Tetragonia tetragonioides (Pall) O. Kuntze in semi-arid regions. During the experiment period, it was measured that several irrigation regimes were affected in terms of growth, biomass production, total yield, mineral composition, and photosynthetic pigments. The experiment was conducted in the greenhouse at the University of Algarve (Portugal). The study lasted from February to April in 2010. Three irrigation treatments were based on replenishing the 0.25-m-deep pots to field capacity when the soil water level was dropped to 70% (T1, wet treatment), 50% (T2, medium treatment), and 30% (T3, dry treatment) of the available water capacity. The obtained results showed that the leaf mineral compositions of chloride and sodium, the main responsible ions for soil salinization and alkalization in arid and semi-arid regions, enhanced with the decrease in soil water content. However, the minimum amounts of chlorophyll, carotenoids, and soluble carbohydrates in the leaf content were obtained in the medium and driest treatments. On the other hand, growth differences among the several irrigation regimes were very low, and the crop yield increased in the dry treatment compared to the medium treatment; thus, the high capacity of salt-removing species suggested an advantage of its cultivation under dry conditions.info:eu-repo/semantics/publishedVersio
Analysis of hadron production in nucleus-nucleus interactions up to and out of kinematical limit of free NN-collisions in the frame of FRITIOF model
In the framework of the modified FRITIOF model, the inclusive spectra of the
cumulative -, -mesons and protons produced in the
nucleus-nucleus interactions at 4.5 GeV/c/nucleon and 4.2 GeV/c/nucleon are
calculated. It is shown that the model reproduces qualitatively, and in some
cases quantitatively the main experimental regularities of -mesons
production, and "soft" part of the proton spectra. According to the model the
production of the cumulative particles is connected with the mechanism of the
"soft" nucleon-nucleon interaction.Comment: 12 pages, 11 figure
Underground polymeric l-shaped pipeline vibrations under seismic effect
The simultaneous equations of longitudinal and transverse vibrations of an underground polymeric L-shaped pipeline under the arbitrary direction of seismic load were derived in the paper. A computational scheme of the problem was constructed using central finite-difference relations. The analysis of the results obtained on the simultaneous longitudinal and transverse vibrations of underground polymeric L-shaped pipelines under seismic loading was conducted. The stress-strain state of the L-shaped polymeric pipeline subjected to seismic effect was determined, and the axial forces and bending moments arising in curved pipelines during an earthquake were determined
Origin of light nuclei in near earth orbit
The possible sources of light nuclei populations observed recently below the
geomagnetic cutoff by the AMS experiment are discussed in terms of nuclear
processes: fragmentation of the incoming flux of cosmic helium on atmospheric
nuclei, and nuclear coalescence from proton and helium induced reactions.
Results of simulations for deuterium, tritium, helium 3 and 4, are presented.Comment: 11 pages, 4 figure
Atmospheric neutrino flux from 3-dimensional simulation
The atmospheric muon and neutrino flux have been simulated using the same
approach which successfully accounted for the recent secondary proton, electron
and positron flux measurements in orbit by the AMS experiment. For the muon
flux, a good agreement is obtained with the CAPRICE and HEAT data for altitudes
ranging from sea level up to about 38 km. The general features of the
calculated atmospheric neutrino flux are reported and discussed. The flux
obtained at the Super-Kamiokande experiment location are reported and compared
with other calculations. For low neutrino energies the flux obtained is
significantly smaller than that used in the data analysis of underground
experiment. The simulation results for the SOUDAN experiment site are also
reported.Comment: 33 pages, 27 figures, 12 tables, final version for Phys. Rev.
