Product development must be continuously done by the chocolate industry to face a high level of competitiveness in the market industry. This study investigates the effect of powdered sappan wood and butterfly pea flower incorporation in milk and white chocolate compounds. Four concentrations of each additional ingredient were used (0, 5, 10 and 15%).

Tropical peatland fires generate substantial quantities of airborne fine particulate matter (PM) and in Indonesia are intensified during El Niño-related drought leading to severe air quality impacts affecting local and distant populations. Limited in-situ data often necessitates reliance on air quality models, like that of the Copernicus Atmosphere Monitoring Service, whose accuracy in extreme conditions is not fully understood. Here we demonstrate how a network of low-cost sensors around Palangka Raya, Central Kalimantan during the 2019 fire season, quantified extreme air quality and city-scale variability.

BACKGROUND Assessment of labor progress via digital vaginal examination is subjective, while intrapartum transperineal ultrasonography is deemed more objective and effective. The angle of descent (AoD) is a reliable intrapartum transperineal ultrasound parameter with minimal inter-observer and intra-observer errors. This study compared intrapartum transperineal ultrasonography with digital vaginal examination in evaluating the angle of descent for vaginal delivery selection in 70 women.

Omphalocele is a congenital anomaly characterized by a structural defect in the abdominal wall that leads to the protrusion of the intestines or other abdominal organs covered by a protective membrane. Approximately 20%-50% of omphalocele cases are associated with trisomy 13, 18, and 21 and result in fetal death. Prenatal diagnosis of omphalocele can be made by late first trimester ultrasound with a sensitivity of 75% and specificity of 95%, or by elevated maternal serum alpha-fetoprotein concentration.

Significant efforts have been dedicated to creating recyclable and efficient methods for treating waste dyes, including rhodamine B (RhB). Nevertheless, challenges such as complex operational techniques, high costs, energy consumption, and inefficacy in dye removal persist. Here, the synthesis and application of TiO/FeO/SiO for photocatalytic degradation of RhB dye pollutants have been explored.
