On December 4, 2016, Jatupat Boonpattararaksa, known by his nickname “Pai,” then a law student at Khon Kaen University in northeastern Thailand, was arrested and accused of violating Article 112 of the Thai Criminal Code, or defaming, insulting, or threatening the king, queen, heir-apparent, or regent. Two days prior, he had shared to Facebook a biography of the new king, Maha Vajiralongkorn, or Rama X, who became king following the death of his father, Bhumipol Adulyadej, Rama IX, on October 13, 2016. The BBC Thai biography was candid and highlighted Vajiralongkorn's string of wives, his four abandoned sons, and his conferral of a military rank on his pet dog, as well as his recent bike rides for charity (BBC Thai 2016). Over 2,600 people shared the BBC Thai link, but Pai was the only person to be arrested in December 2016 and the only person to be prosecuted to date (TLHR 2017a). The complaint that led to Pai's arrest was filed by Lieutenant Colonel Phitakphon Chusri, a Khon Kaen–based soldier who has followed him closely.

AbstractBackground: Rheumatic fever (RF), rheumatic heart disease (RHD), and congenital heart disease (CHD) are still major problems among Thai school children.Objective: To examine trends in the prevalence of RF/RHD and CHD along with the socioeconomic status of school children in urban Khon Kaen, northeastern Thailand.Methods: We conducted cross-sectional survey of 8,555 school children aged 5-15 years from 4 schools in urban Khon Kaen from January to March 2006. Pediatric cardiologists examined the school children and all cardiac diagnoses were confirmed by echocardiography. Socioeconomic data were also collected. Schools were divided into high and low socioeconomic status (SES) schools, based on the prevailing levels of parental education and household income. All positive cases of heart disease were followed and reviewed at a university hospital up to December 2013.Results: Of 8,555 children examined, 2 had RF/RHD, and 10 had CHD. The prevalence of RF/RHD was 0.23 per 1,000 (95% CI 0.03-0.84), and the prevalence of CHD was 1.2 per 1,000 (95% CI 0.56-2.15). Prevalence of RF/RHD among urban school children in the center of northeastern Thailand had declined from 1.13 to 0.23 per 1,000 since 1986. The indices of socioeconomic development revealed marked improvement during this 20 year interim. The prevalence of RF/RHD was higher among low SES schools (4.6 per 1,000) compared with high SES schools (0 per 1,000).Conclusion: There is a low prevalence of RHD in school children in this region compared with the period before 1986.

Foodborne disease associated with Salmonella spp. occurs in some parts of the world, including Thailand. The present study aimed to determine prevalence, antimicrobial resistance, and serotypes of Salmonella spp. isolated from chicken meat in upper northeastern Thailand. A total of 326 swab samples of fresh chicken meat were collected from wet markets in Khon Kaen, U-don Thani, Nong Khai, Loei, Kalasin, Maha Sarakham, and Bueng Kan Provinces, northeastern Thailand, between August and November 2019. All samples were analyzed for Salmonella spp. using the ISO 6579:2002/AMD 1:2007 method. The isolates were tested for antimicrobial susceptibility using the Kirby-Bauer method, and the serotypes of isolates positive were identified. The overall prevalence of Salmonella spp. isolated from chicken meat was 36.2% (118/326), and prevalence in the provinces was as follows: U-don Thani, 70.9%; Bueng Kan, 66.67%; Khon Kaen, 45.9%; Kalasin, 31.25%; Nong Khai, 29.8%; Maha Sarakham, 26.42% and Loei, 12.5%. Resistance was highest for nalidixic acid at 31%, followed by ampicillin (24%), tetracycline (19%), sulfamethoxazole trimethoprim (8%), norfloxacin (5%), ciprofloxacin (4%), amoxicillin (4%), and chloramphenicol (1%). However, all isolates were susceptible to ceftazidime. Twenty-seven serotypes were detected, with the Corvallis, Singapore, Kentucky and Agona serotypes being the most common. Salmonella spp. were detected in a large percentage of the swab samples of chicken meat in every city, indicating a high level of contamination of chicken meat. Given the high resistance of Salmonella strains to some antibiotics, it may be beneficial to find other drugs for salmonellosis treatment and to use antibiotics more wisely.

Erosion rate on corals due to activities of other biota is called bioerosion. The rock-boring urchin, Echinometra mathaei, when it is abundant, plays a significant role in benthic ecosystems, including biological processes like coral erosion. During feeding, E. mathaei erodes calcium carbonate besides grazing on algae living on coral, so it plays an important role in both organic and inorganic carbons in coral reefs. The urchin E. mathaei actively feeds during the night time (nocturnal grazer). Although in Okinawa four types (A-D) of the urchin exist, the research only focused on the types A and B. Type A of E. mathaei produced 0.44951 g feces per day on average while type B produced 0.38030 g feces per day. CaCO3 analysis in feces and gut contents showed bioerosion rate of E. mathaei type A was 0.64492 g/individu/day, and 0.54436 g/individu/day in type B. There were no significant differences in bioerosion impact of E. mathaei type A and B© Laju erosi pada karang yang disebabkan oleh biota, dikenal dengan bioerosi. Bulu babi jenis Echinometra mathaei, ketika melimpah, menjadi sangat berpengaruh terhadap ekosistem bentik termasuk proses biologi seperti erosi karang. Selama aktivitas makan, E. mathaei menggerus kalsium karbonat dalam proporsi yang besar di samping alga yang tumbuh menempel pada karang sehingga memiliki peran penting dalam siklus karbon organik dan anorganik di ekosistem terumbu karang. Bulu babi E. mathaei aktif mencari makan pada malam hari (nocturnal grazer). Meskipun di Okinanawa ada 4 tipe (A-D), pada eksperimen kali ini memfokuskan pada tipe A dan B saja. Tipe A E. mathaei rata-rata memproduksi 0,44951 g feses/hari dan tipe B memproduksi 0,38030 g feses/hari. Berdasarkan analisis CaCO3 yang dilakukan pada feses dan isi lambung, laju bioerosi yang disebabkan oleh E. mathaei tipe A sebesar 0,64492 g/individu/hari sedangkan tipe B sebesar 0,54436 g/individu/hari. Tidak terdapat perbedaan dampak bioerosi yang signifikan antara E. mathaei tipe A dan B©

Abstract The effect of silver carp (Hypophthalmichthys molitrix Val.) feeding activity on the plankton communities in a high-rate pond technology system (HRPTS) effluent was investigated over a period of 100 days. The experiment was conducted at the experimental wastewater treatment plant of the Agronomic and Veterinary Medicine Institute (AVI) of Rabat, Morocco, using a HRPTS in a fish pond receiving the plant effluent. The effluent was highly dominated by phytoplankton (99.95%). Silver carp could survive and grow in the fish pond. Production was 37 kg with a very low mortality rate (12%). The high specific intestine weight (7%) and intake rates of biomass and phytoplankton by silver carp (616 g kg-1 of fish day-1 and 1.6 x 1011 cell kg-1 of fish day-1, respectively) demonstrated the importance of the feeding activity of the fish. Zooplankton intake rates were lower (2 x 107 bodies kg-1 of fish day-1). The high intestine index (3 to 4.3 for fish sizes of 14 to 22 cm) and the dominance of phytoplankton in the gut contents (99.95%) confirmed an omnivorous/ phytoplanctivorous diet. Silver carp were efficient in removing plankton from the HRPTS effluent. The net removal yields of biomass were 285 g m-3 day-1 and 322 g kg-1 of fish day-1, 7 x 1010 algal cells kg-1 of fish day-1 and 8.7 x 107 zooplankton bodies kg-1 of fish day-1, with net removal rates of 47, 64 and 62%, respectively. The total suspended solids concentration decreased from 211 in the inflow to 112 mg L-1 in the fish pond.

Abstract The purpose of this study is to investigate the future runoff into the Nong Han Lake under the effects of climate change. The hydrological model Soil and Water Assessment Tool (SWAT) has been selected for this study. The calibration and validation were performed by comparing the simulated and observed runoff from gauging station KH90 for the period 2001–2003 and 2004–2005, respectively. Future climate projections were generated by Providing Regional Climates for Impacts Studies (PRECIS) under the A2 and B2 scenarios. The SWAT model yielded good results in comparison to the baseline; moreover, the results of the PRECIS model showed that both precipitations and temperatures increased. Consequently, the amount of runoff calculated by SWAT under the A2 and B2 scenarios was higher than that for the baseline. In addition, the amount of runoff calculated considering the A2 scenario was higher than that considering the B2 scenario, due to higher average annual precipitations in the former case. The methodology and results of this study constitute key information for stakeholders, especially for the development of effective water management systems in the lake, such as designing a rule curve to cope with any future incidents.
