Summary of competition results compared to total distance run, Sprint run, Number of Sprints, High-intensity running in amateur soccer players. There is no difference. But the result of losing in a soccer match is a high trend in total distance run, Sprint run, High-intensity running in amateur soccer athletes.

Basketball Small-Side Game Training Intensity: Comparative Study of Scoring Format between One and Two Hoops Shooting

2025-04-30T14:26:34+07:00

This study aimed to compare the intensity encountered during a basketball small-sided game (SSG) with one hoop and two hoops. Twelve male basketball players (18–22 yrs) from Kasetsart University, Kamphaeng-Saen campus were recruited to participate. The subjects were equally assigned to four teams with 3 players in each team. All players performed 3v3 small-sided games training on a half court, each team played the two SSG (one hoop and two hoops) against each other in a random order. During the different SSG formats, Heart Rate (HR) was recorded using the Polar Team Pro System. A paired t-test was calculated for each dependent variable, The results show that the SSG with one hoop significantly average Heart Rate (HR), Maximal Heart Rate (HRmax), and percentage Maximal Heart Rate (%HRmax) values compared with the SSG with two hoops (P < .05). Furthermore, the Percentage of time spent above 85%HRmax, Average Heart Rate, Maximal Heart Rate, and Percentage Maximal Heart Rate and Rating of Perceived Exertion (RPE) during two SSG formats showed significantly correlated with VO2max (P<05) These data suggest that two SSG formats could be prescribed for squad management to conditioning stimuli for specific players and provide a high stimulus for physical conditioning and technical improvement for basketball players.

Production Of Bio-Ethanol from Banana Peels by Using Baker’ S Yeast

2025-04-30T15:38:08+07:00

The objective of this research is to explore the utilization of banana peels for ethanol production. The pretreatment conditions explored were with 0, 2.5 or 5% sulfuric acid at room temperature (RT) or autoclaved at 121°C (AU). Pretreating with 2.5% H₂SO₄ AU increased the cellulose content and reduced the hemicellulose content by 52.13 ± 8.95% and 30.67 ± 2.67% respectively (p<0.05). In contrast, the reducing sugar content of the 2.5% H₂SO₄ AU pretreated sample was lower than that of the distilled-water-pretreated-with-autoclave sample (Water AU) and was not significantly different from that of the non-pretreated sample at p<0.05 (84.60 ± 11.82 mg/g, 296.13 ± 22.25 mg/g and 117.38 ± 4.21 mg/g, respectively). Further analysis of the hydrolysis conditions showed that the non-pretreated banana peel sample hydrolyzed with 10% w/v H₂SO₄ at 50°C for 24h yielded the highest amount of reducing sugar (92.49 ± 3.45 mg/g) compared to other samples at p<0.05. The best fermentation condition for the hydrolyzed non-pretreated sample using baker’s yeast was found to be at 18 hours fermentation time, 35°C, and shaking speed at 150 rpm. The content of ethanol (P), the ethanol yield (Y_P/S) and the fermentation efficiency (E_Y) were measured at 7.26 mg/g, 0.09 mg/mg and 17.05 ± 0.09% respectively (p<0.05). This study shows that banana peels have a potential to produce ethanol, but the yield may be too low. Further research is needed to increase the yield of this process.

Influence Of Solvent, Cellulose Acetate Butyrate in Ninhydrin Solution on The Detection of Latent Fingerprints on Thermal Paper

2024-06-03T19:31:51+07:00

This research studies the influence of solvent, cellulose acetate butyrate in ninhydrin solution on the detection of latent fingerprints on thermal paper. Thermal paper is often used as financial evidence in bank automatic teller machine (ATM) transactions and as receipts from convenience stores. These receipts are considered as forensic evidence that can help detect the fingerprints of suspects. The study found that acetone discolors thermal paper more brown-black than petroleum either. Adding cellulose acetate butyrate (CAB) to both types of ninhydrin solution, it was found that the brown-black color of the thermal paper had decreased. Optimal concentration of CAB in solution of acetone/ninhydrin and petroleum ether/ninhydrin were 1.0 and 0.5 %wt., respectively. It suggested the whiteness index of the thermal paper being 80.78 ± 3.63 % and 61.28 ± 11.89 %, respectively. In addition, the latent fingerprints examined with all types of ninhydrin solution in this research before and after the ageing study at different times showed that the minutiae of latent fingerprints were similar to using the forensic ninhydrin solution. It was found that the minutiae of latent fingerprints showed a value more than 10 points, which could use to verify a person. Moreover, the CAB incorporation indicated that the rate of decline of minutiae of latent fingerprints decreased, especially in the case of 0.5 %wt. CAB/ninhydrin/petroleum ether. The ninhydrin solution in this research is considered an alternative
method for detecting latent fingerprints on thermal paper by manually counting minutiae with the naked eye, without using an AFIS machine. In addition, it is inexpensive in chemical composition and easier to prepare.

Estimates of Genetic Variation, Genetic Advance and Heritability in S1 line Population of Waxy Corn

2025-04-30T11:24:35+07:00

The study aimed to assess genetic variation in agricultural characteristics, fresh-ear yield, and eating quality of S₁ lines population of waxy corn, which is in the cycle 3 of recurrent selection. The 288 lines were split into 2 sets, 141 lines each. Three commercial varieties (SW254, Sweet White, and Big White) were used as check. The experiment was conducted using alpha-lattice design (12x12) with 2 replications at the experimental plot of Kasetsart University, Kamphaeng Saen Campus from June to October 2021. It showed statistically significant differences for green and white weight, ear length and number of kernel rows. Estimates of GCV and PCV ranged between 5.6% and 28.9%. The highest GCV and PCV value were found particularly for green and white weight and ear height with moderate heritability values were also found for both traits and their genetic advance over mean (GAM) was ranged 8.0-19.0%. Means of fresh-ear yield and ear length of the selected S₁ lines trends to be better than that of population and check mean. It indicates that existence of genetic variation in the population should be exploited in future breeding for fresh-ear yield.

Cannabidiol in Veterinary Medicine: A Systematic Review of Efficacy, Safety, and Economic Considerations Compared to Conventional Treatments

2025-04-30T12:07:30+07:00

This study presents a systematic literature review on the use of cannabidiol (CBD) in veterinary medicine, aiming to compare its efficacy, safety, and cost-effectiveness with conventional treatments. Analysis of 25 research articles published between 2013-2023 reveals that CBD demonstrates promising efficacy in managing pain, epilepsy, and anxiety in animals, with fewer side effects compared to conventional medications. However, most studies are limited by small sample sizes and short duration. Cost-effectiveness analyses indicate that despite higher initial costs, CBD may be more economical in the long term due to reduced side effects. Significant challenges include varying legal status across countries and ethical considerations, particularly for livestock. The review concludes that CBD shows potential as an alternative treatment in veterinary medicine, but further research is needed. Recommendations for future studies include long-term trials, broader species diversity, and investigation of drug interactions to ensure widespread and safe application in veterinary practice.
