Authors: Adwan N. H. Al-Ajili
Published: April 2023

Lifetime of photoluminescence emitted by porous silicon has been investigated by using pulsed nitrogen laser as excitation source. This research also involved sample preparation. This in itself necessitated software and hardware development to enable interfacing and data logging using PC.                        

Orange and orange/red photoluminescence emitted from porous silicon samples have been studied at temperatures (77 - 295) K. The photoluminescence decay was intrinsically nonexponential at different temperatures. The photoluminescence lifetime, defined as 1/e times the initial intensity, decreased as emission energy increased, and increased with decreasing temperature. The time evolution of photoluminescence lifetimes  and  for orange porous silicon sample has been investigated.

Authors: S. A. Wuhaib  , Akram S. Mohammed  , Zeyad. M. Abdullah
Published: April 2023

In this paper, we introduce the notions of interval-valued anti fuzzy prime (resp. strongly prime and semiprime) bi-ideals of semigroup. By using these ideas, we characterize those semigroup for which each interval anti-fuzzy bi-ideal is semiprime and strongly prime.

Introduction: The theory of fuzzy sets proposed by Zadeh [6], in his classic paper of 1965, deal with the applications of fuzzy technology in information processing. Mordeson, Malik and Kuroki gave a systematic exposition fuzzy semigroups in [2], where one can find theoretical results on fuzzy semigroups. Shabir and Kanwal [5], introduced the concept of prime bi-ideal, strongly prime bi-ideals and semiprime bi-ideal of a semigroup and studied those semigroups.

In this paper we introduced the   concept of interval valued anti fuzzy prime, strongly prime and semiprime bi-ideal of semigroups and give characterization of semigroups in terms of these notions we characterize those semigroups for which each interval-valued anti fuzzy bi-ideal is semiprime and strongly irreducible.

From 1st Jan2009 to31th of Dec 2009 a total of 1406 women sera with abortions and outcomes of congenital abnormalities in Kirkuk city were screened for infections like Chlamydia trachomatis, Toxoplasma gondii and cytomegalovirus (CMV).These agents were determined in sera using commercial Elisa diagnostic kits.

Results of the study showed that CMV infection was more prevalent 39.74 % followed by Toxoplasmosis 16.37 %and Chlamydial infection 14.67 %.High rates of Toxoplasmosis and CMV were recorded among women aging from 15 to 25 year, while high of Chlamydial infection was recorded among women aging 26 to 35 years P<0.05. Sera of non-pregnant women reveal high rate of Chlamydial infection, while toxoplasmosis and CMV were exert in sera of pregnant women. High rates of IgM antibodies 8.33 %and 11.41 % were recorded with CMV and Chlamydia respectively compare to 3.84 % for toxoplasmosis ,P<0.05. Cross reactions rate among three microorganisms were detected in 29 sera with the rate 2.52 %, which divided in to 2.10 % for Chlamydia pulse Toxoplasma and 0.69 % for Chlamydia pulse CMV. Two serum samples show 0.54% of mixed IgM antibodies of Chlamydia, toxoplasma, CMV and rubella, the rate was 0.14 %.

Conclusion: The present study demonstrates a strong association between the infectious agents (Chlamydia, Toxoplasma and CMV) and women abortion and congenital outcomes. It is therefore recommended that all antenatal cases with such history should be routinely screened for these agents. Chlamydia IgM test should be added to preventive tests prior to marriage and parallel to toxoplasma test, CMV and rubella during screening for women abortion and congenital anomalies.

Authors: Hussein Hassan Kharnoob  , Hasan Ahmed Hasan
Published: April 2023

Two plants species were used to study the uptake of heavy metals by plants; these were Lolium perenne and Cock's Foot. The species were grown in Hoagland's solution with double concentration of phosphate for one week; the roots species were cut and grown in Hoagland's solution without phosphate to prevent precipitation of any metal phosphate. Four experiments were run with a composite rotatable design with three variables and at five levels (-1.68,-1,o,+1,+1.68) was used. The metals were added as metal nitrate to Hoagland's solution in which the plants are grown on a logarithmic scale and after one week of grown the roots and shoots of plant were cut and digested with concentrated nitric acid and examined for metals by atomic absorption spectrophotometer. This research proved that some elements increased the absorption of other elements in growth solution to the shoot through root while other elements interfere the absorption phenomena for example zinc effects on absorption of copper
