Field behaviour geotextile reinforced sand column
Tandel, Yogendra K.,Solanki, Chandresh H.,Desai, Atul K. Techno-Press 2014 Geomechanics & engineering Vol.6 No.2
Stone columns (or granular column) have been used to increase the load carrying capacity and accelerating consolidation of soft soil. Recently, the geosynthetic reinforced stone column technique has been developed to improve the load carrying capacity of the stone column. In addition, reinforcement prevents the lateral squeezing of stone in to surrounding soft soil, helps in easy formation of stone column, preserve frictional properties of aggregate and drainage function of the stone column. This paper investigates the improvement of load carrying capacity of isolated ordinary and geotextile reinforced sand column through field load tests. Tests were performed with different reinforcement stiffness, diameter of sand column and reinforcement length. The results of field load test indicated an improved load carrying capacity of geotextile reinforced sand column over ordinary sand column. The increase in load carrying capacity depends upon the sand column diameter, stiffness of reinforcement and reinforcement length. Also, the partial reinforcement length about two to four time's sand column diameter from the top of the column was found to significant effect on the performance of sand column.

Background: Candiduria is a common phenomenon among hospitalized patients, particularly those in intensive care units (ICUs), wherein multiple predisposing factors such as comorbidities, indwelling urinary catheters, and antimicrobial exposure contribute to its prevalence. Objective: This study aims to investigate the epidemiological trends and antifungal susceptibility patterns of Candida spp. isolated from urine samples of patients at a tertiary care center in Western Maharashtra, India. Methods: Of the 7,642 urine samples received between 01 June 2022 to 31 May 2023, 142 samples (9%) displayed the growth of Candida species. Upon retesting samples from these patients, only 70 true positive results were identified. All the isolates were detected via VITEK MS (bioMerieux, France), while antifungal susceptibility testing (AFST) was conducted using the VITEK 2 Compact with an AST-YS08 card. Results: The most common isolate was Candida tropicalis (50%), followed by Candida albicans (25.7%). Rare Candida species (e.g., Candida ciferrii, Candida kefyr, Candida metapsilosis, Candida utilis) collectively contributed to 7.1% of all Candida species. The results of the AFST revealed a high sensitivity to amphotericin B and echinocandins. Fluconazole resistance was observed in 6% of the isolates. Candida ciferrii demonstrated a distinct pattern, indicating a statistically significant association (p = 0.015) when the patient had two or more comorbidities and resistance to azoles, which was statistically significant (p-values for fluconazole (p = 0.015), voriconazole (p = 0.004), and flucytosine (p = 0.002)) when compared with other Candida species. Conclusion: Resistance trends in India have been changing with increased fluconazole-resistant Candida strains being frequently isolated, emphasizing the importance of customized therapeutic strategies based on culture and sensitivity reports.
