Th. conformity of Saudi dates cultivars to date standards h.s not been studied extensively. In th.s study, microbial loads and ph.sicoch.mical ch.racteristics of four Saudi date cultivars (Sukkary, Kh.las, Sugai and Anbara) were determined. Anbara cultivar h.d significantly h.gh.r mould and yeast counts th.n recommended under Saudi tech.ical regulation and standards for packaged wh.le dates. Moisture content and insect damage for all studied cultivars fell with.n Codex standards. Single fruit weigh. for pitted and unpitted dates was h.gh.r th.n recommended under international standards. Date cultivar h.d a significant effect on fruit color th.s fruit color sh.uld be included in Saudi tech.ical regulation and standards for date grading.

作者： hassan h. Moh.mmed Department of Computer Tech.ology Engineering Iraq University College Basrah Iraq

Th.s paper is directed to study th. isotope effects of some superconducting materials th.t h.ve a strong coupling coefficient λ > 1.5, and focuses on new superconducting materials wh.se critical temperature is close to room temperature, specifically Lah.sub>10-LaD10 and h.sub>3S-D3S systems. Th. Eliash.erg-McMillan (EM) model and th. recent Gor’kov-Kresin (GK) model for evaluating th. isotope effects coefficient α were examined for th.se systems. Th. predicted values of α as a function of pressure, as compared to experimental values led to inference th.t th.se two models, despite th.ir importance and simplicity, cannot be considered complete. Th.se models can be used to calculate isotope effect of most superconducting materials with.strong coupling coefficients but with.critical reliability. Th. significance of studying th. isotope effect lies in th. possibility of identifying th. interatomic forces th.t control th. properties of superconducting materials such.as electrons-mediated ph.nons and Coulomb interactions.

We present a th.oretical study on th. composition dependence of th. surface ph.non polariton （SPP） mode in wurtzite structure α-InxGa1-xN ternary alloy over th. wh.le composition range. Th. SPP modes are obtained by th. th.oretical simulations by means of an anisotropy model. Th. results reveal th.t th. SPP mode of α-InxGa1-xN semiconductors exh.bits one-mode beh.viour. From th.se data, composition dependence of th. SPP mode with.bowing parameter of-28.9 cm^-1 is th.oretically obtained.

Th. proposal of quantum simulation provides a h.gh.y effective approach.for experimental research.on open quantum systems. To date, numerous quantum simulation studies pertaining to open quantum systems h.ve been put forward,including Fanch.ni et al.’s simulation of a deph.sing noise ch.nnel utilizing an optical system[1], and Xiong et al.’s realization of a quantum simulation for a non-rotating-wave approximation noise ch.nnel, also leveraging an optical system[2].

In 1872, George h.ntington presented h.s essay “On Ch.rea” to th. Meigs and Mason Academy of Medicine and, in doing so, detailed a disease th.t would later bear h.s name. h.ntington's disease(h.) is a genetic, neurodegenerative disease th.t manifests as th. loss of motor control,cognitive impairment,and mood and psych.atric ch.nges in paents.

A process for purifying aqueous solutions containing h.avy and toxic metals such.as ch.omium（Cr） h.s been investigated. One of th. extremely h.rmful pollutants in rivers and seawater is th. h.avy metal ions due to th.ir direct impacts on h.man, animals and plants are h.xavalent Cr（Ⅵ）. Consequently, h.gh.y sensitive sensor to detect Cr is essential. Surface plasmon resonance（SPR） tech.ique h.s attracted h.ge research.interest in detecting h.avy metals specifically. In th.s study, th.ee types of prism-based SPR sensor, gold（Au）/silver（Ag）, Au/polyaniline（PANI） and Au/titanium dioxide（TiO2） nanostructured films, are investigated as potential sensing material to detect th. presence of Cr（Ⅵ） ions in water. Th. base Au layer with.th.ckness of 48.3 nm is deposited on a glass slide for all sensors. For Au/Ag, Au/PANI nanofibers and Au/TiO2sensor films, th. Cr（Ⅵ） concentration is varied from 1 ppm to 15 ppm with.sensitivity of 0.270 °ppm-1, 0.082 °ppm-1and 0.039 °ppm-1, respectively. Based on th.se results, th. Au/PANI nanofibers are th. most sensitive to Cr（Ⅵ） among th. tested sensing materials.

We use effective field th.ory （EFT） for th. calculation of neutron-deuteron radiative capture at very low energies. We present h.re th. use of EFT to calculate a low-energy ph.to-nuclear observable in th.ee-body systems, th. ph.ton polarization parameter and and fore-aft asymmetry at th.rmal neutron energies up to next-to-next to leading order （N2 LO）, with.inclasion of th. electric quadrupole contribution. Th. ph.ton polarization parameter in total is found to be Rc = -0.421±0.003 and is in good agreement with.th. oth.r modern th.oretical calculations based on modern nucleon-nucleon potentials. In comparison with.our previous work, a satisfactory agreement with.th. available experimental data is found by inclusion of th. electric quadrupole contribution.
