The Effect of Inlet and Outlet Pattern on a Parabolic Dome Solar Collector

Phoothanet Saengcharoon — 2026-07-01

This research aims to investigate the effects of air inlet and outlet patterns on parabolic-dome solar collectors. A three-dimensional transient computational fluid dynamics (CFD) simulation in ANSYS Fluent was used to analyze sixteen different inlet-outlet patterns and compare their effects on air behavior, outlet air temperature, and thermal efficiency. Simulation results show that most patterns led to recirculating air, resulting in hot spots and reduced heat transfer efficiency. Conversely, pattern 3-2 exhibited the most uniform air distribution. This 3-2 pattern also had an outlet air temperature and average thermal efficiency of about 42.75°C and 41.97%, respectively. Furthermore, the numerical model was validated using statistical indicators R², MRD, and RMSE, which showed that the model results were highly consistent with the experimental results (R² = 0.9942, MRD = -0.031°C, and RMSE = 3.656°C). These observations underscore the critical role of the inlet-outlet pattern in optimizing airflow and improving heat transfer efficiency. Therefore, this study presents an effective design for air inlet-outlet patterns that improves the efficiency of parabolic dome solar collectors through an optimized air channel design.

Assessment of Milking Hygiene Practices and Raw Goat Milk Quality: A Case Study of a Dairy Goat Farm in Narathiwat Province, Thailand

Panida Paopradit — 2026-07-08

The quality of raw goat milk is largely affected by farm management and milking hygiene, especially in small-scale production systems. This study aimed to assess milking hygiene practices and their relationship with the physical, chemical, and microbiological quality of raw goat milk from a dairy goat farm in Southern Thailand. Milking practices were evaluated through direct observation and structured consultations with the farm personnel. Milk samples were collected on three occasions, resulting in a total of 24 samples for laboratory analysis. The results showed that the milk's physical properties and chemical composition were within acceptable ranges, indicating generally adequate nutritional quality. Total coliform counts and thermoduric bacteria ranged from 2.81×10¹ to 5.00×10¹CFU/mL and 3.75×10¹ to 1.49×10² CFU/mL, respectively, and Salmonella sp. was not detected in any sample. However, a consistently high prevalence of presumptive Staphylococcus aureus and markedly elevated somatic cell counts were observed across all samples, indicating strong evidence of subclinical mastitis, with mean values of 6.81×10⁴ CFU/mL and 2.83×10⁶ cells/mL, respectively. These findings may indicate limitations in milking hygiene and udder health management. Furthermore, antibiotic residues were detected in 54.17% of the evaluated samples, suggesting potential non-compliance with prescribed veterinary withdrawal periods. Overall, these findings highlight important gaps in current milking hygiene and herd health management practices, which may compromise raw milk safety and quality. Although the single-farm scope of this study limits the broader generalizability of the insights across diverse dairy goat production systems, the evidence underscores that optimizing milking sanitation, refining mastitis monitoring, and enforcing the prudent administration of veterinary drugs are imperative to safeguard raw goat milk quality at the farm level.

Effect of Nine-Square Counting Dance on Physical and Cognitive Function in Older Adults with Mild Cognitive Impairment: A Randomized Controlled Trial

Donlaya Phisitsettakorn — 2026-08-03

The cognitive impairment was increasingly prevalent with advancing age and was associated with an elevated risk of falls, injury, functional decline, and cognitive impairment. This study aimed to investigate the impact of a four-week integrated intervention involving a nine-square dance and a counting program on physical function by the Timed Up and Go Test (TUGT), the five-times sit-to-stand test (FTSST), 10-meter walk test (10MWT), 6-minute walk test (6MWT), and cognitive functioning by the Mini-Mental State Examination (MMSE) in older adults diagnosed with mild cognitive impairment. A single-blinded randomized controlled trial was conducted in Thailand, involving 38 older adults from the community, each aged 60 years or older. In a random selection process, participants were designated to either the control group (which participated in the nine-square dance: CONT) or a nine-square counting dance (NSCD) intervention. The finding indicated that the NSCD group demonstrated a positive effect of the intervention on the overall cognitive test in MMSE (mean change of 4.67 points, p < 0.001). Moreover, statistically significant differences were observed between the groups across all physical function outcome measures (p < 0.01 or p < 0.001), except for the 10MWT. Therefore, the nine-square counting dance intervention was more effective in enhancing cognitive and physical performance among older adults exhibiting mild cognitive impairment when compared to the nine-square dance modality alone.
