The physical health of adolescents in Bhutan is of national importance, with rising non-communicable diseases (NCDs) like obesity and cardiovascular conditions necessitating early intervention. However, the current physical education (PE) curriculum has shown limited effectiveness in improving health-related fitness (HRF) due to insufficient activity frequency and targeted interventions. This study addresses this gap by evaluating a structured Physical Activity Program (PAP) grounded in the F...

Our case study, a distribution network, had a high rate of lost sales due to a mismatch between the inventory level and the demand and the variability of peddling demand. Three main inventory replenishment policies were required: Regular and urgent orders to the factory and lateral transshipment orders between distribution centers. Moreover, two types of demands are considered: pre-order and peddling demands. A spreadsheet model simulated this system to compare a set of proposed inventory rep...

Sugarcane harvesters are agricultural machines that has an important role in the sugarcane industry in Thailand. They improve the harvesting process by reducing labor dependency and reducing the air pollution (PM2.5) caused by sugarcane burning in Thailand. This research aimed to study the performance of sugarcane harvesters being used in Lower North region, physical properties and shear forces of sugarcane billets and the effect of base cutters to provide the data for developing the sugarcan...

Curcumin is a multitherapeutic agent with great therapeutic potential in central nervous system (CNS) diseases. However, its hydrophobicity and low bioavailability hinder its application. To circumvent these drawbacks, we developed polymer-based and lipid-based curcumin nano-formulations. This study aimed to compare the physicochemical properties, in vitro release studies, permeation studies in Caco-2 cells and antidepressant activity of polymer-based and lipid-based of curcumin nano-formu...

  The premature loss of primary molars in children is often caused by chronic pulpal infection from dental caries involved in the pulp, resulting in extensive root resorption and bone destruction. The erupting premolars underneath their infected predecessor were erupting without bone coverage or bone crypt, unlike normal tooth shedding. Such premolars may erupt earlier than those in the physiologic stage. This study aimed to compare the eruption rate of premolars following the extraction of t...
