Centrifugal concrete products are manufactured using specific technology that changes the concrete proportion during consolidation. The bleeding of water reduces the water-to-cement ratio and increases the compressive strength of concrete. This affects the strength of the concrete determined on conventional casted cylinders, centrifuged hollow cylinders, and drilled cores from piles.

Garlic has been utilized since ancient times for both culinary and medicinal purposes. Recent research has identified selenium compounds in garlic, including γ-Glutamyl-Se-methylselenocysteine (GGMSC), leading to the hypothesis that GGMSC acts as a carrier for Se-methylselenocysteine (MSC). Experiments conducted on animals by researchers indicate that the effects of GGMSC in garlic and MSC on cancer cells in experimental models are equivalent. This finding suggests that garlic is a potential chemotherapeutic agent to enhance cancer treatment.

The study was carried out in Wistar rats for 4 consecutive weeks by oral administration at the doses of 0.77 and 2.32g/kg/day. After treatment, no significant treatment-related abnormalities were observed at both doses of Boga-TN, compared to the control group, except for the white blood cells, with lower neutrophil but higher lymphocyte values observed in the treated animals. Histopathology assessment did not show any significant variation between control and treatment groups during the study period.
