Background: The goal of this study is to develop a feasible and sustainable solution to manage the use of industrial wastes of ground granulated blast-furnace steel slag (GGBS) activated by cement kiln dust (CKD) and quicklime (QL). Using activated GGBS in the manufacture of stabilized green bricks is still uncommon in Egypt in such applications. Five clay-based mixtures, each with varying replacement ratios (5–10, wt.%) of CKD and QL, were studied. Laboratory tests were conducted on cylindrical specimens made from these mixtures, which were left to cure for periods of up to 60 days. The raw materials and lab-made specimens were analyzed using particle size analysis, differential thermal analysis, X-ray fluorescence, and X-ray diffraction techniques. The physical and mechanical properties of the cured specimens were also determined and evaluated according to standard specifications. Furthermore, the durability of the cured specimens was evaluated against collapsibility in water. ResuIts: It has been observed that adding QL and CKD to the stabilized green specimens of different mixes can enhance their engineering properties with curing age increasing. This is due to the pozzolanic reaction, which fills the pore structure with calcium silicate hydrates and calcium aluminate hydrates gel. The ratio of QL and CKD used significantly affected the engineering properties of the specimens. The study found that using 20% GGBS and 5% QL led to an increase in compressive strength (266 kg/cm2) at the density of (2.15 g/cm3), while also water absorption was reduced (8%) to give superior results. When GGBS and CKD were combined, a higher content of CKD (10 wt.%) gave better results compared to (5 wt.%) CKD. Furthermore, the physical and mechanical properties of the tested specimens (MD 1, MD II, MD III and MD IV) met the acceptable limits of dry compressive strength (30–70 kg/cm2), water absorption (8–15%), and density (1.7–2 gm/cm3), as specified by the Egyptian standard specifications for buildings used compressed earth blocks. Conclusion: The CKD and QL act as alkali activators for GGBS and can be utilized in masonry construction. [ABSTRACT FROM AUTHOR]

Helicobacter pylori is considered as the main risk factor in the development of gastric cancer. In the present study, anti- H. pylori activity of Lactobacillus fermentum GBF and its fermented antimicrobial products of fermented skimmed bovine milk were investigated. The whey containing Lb. fermentum and its products after skimmed bovine milk fermentation showed powerful antimicrobial activity against H. pylori. In addition, micro filtered soluble peptides of skimmed bovine milk fermented by Lb. fermentum GBF achieved powerful H. pylori inhibitory effect at different concentrations with the highest Minimum Bactericidal concentration (MBC) observed at 1:8 soluble peptides dilution when compared with Lb. fermentum GBF fermented MRS and unfermented skimmed bovine milk. The results demonstrated that fermented bovine milk with Lb. fermentum GBF is a very good candidate as a prophylactic for the protection of humans against H. pylori infections.

This study was conducted to evaluate the quality of raw cow milk at the farm level which considered the first step for production of safe and high quality milk. A total of 150 raw cow milk samples were collected from governmental and private farms at Alexandria Governorate, Egypt. The samples were analyzed for bacteriological properties. The mean values of TBC, coliforms,Staphylococcus aureus and Aeromonas hydrophila count in positive samples were 3.22 x 104 ± 7.28 x 10³, 1.4 x 10³ ± 3.9 x 10², 5.26 x10² ± 8.1 x 10 and 6.4 x10 ± 1.3 x 10 in examined raw cow milk collected from governmental farms while the respective counts in raw cow milk collected from private farms were 1.51 x 105 ± 2.59 x 104, 3.28 x 10² ± 4.7 x 10, 2.95 x 10² ± 7.7 x 10 and 6.8 x10 ± 4.1 x 10. Also prevalence of some pathogens as E. coli,Salmonellae and Yersinia enterocolitica organisms were detected .The hygienic as well as the public health significance of raw milk were discussed.
