Background & Aims: Hydronephrosis is a common problem in prenatal and newborn infants diagnosed by ultrasonography. Bladder to ureter reflux, the upper or lower urinary tract obstruction, and neurogenic bladder are the most common causes of hydronephrosis in newborns and infants. Methods: In this study, 100 neonates and infants with hydronephrosis were observed clinically and laboratorically fo...

Plastic debris is one of the major environmental concerns for the coastal area of Brunei Darussalam. It reduces the aesthetic appeals of the beaches in the country. The current study investigates marine debris on six different beaches of Brunei Darussalam along the South China Sea. Plastic was found the most abundant among whole debris by number (90.02%) and by weight (39.12%). It was classifie...

This work deals with various investigations into the accuracy of a newly developed planar nanopositioning machine. machine, called Nanofabrication Machine 100 (NFM-100), has positioning range mm in diameter. To determine precision, movement scenarios are performed machine table, and trajectory deviation from set is determined. In particular, focus on high velocities up to 20 mm/s. Even at speed...

Stumps account for a large proportion of coarse woody debris in managed forests, but their decay dynamics are poorly understood. The loss of mass and the degree of humification of the above-ground woody debris, below-ground woody debris, bark and root system (R1, 10 mm ≥ diameter > 0 mm; R2, 25 mm ≥ diameter >10 mm; 100 mm ≥ R3 > 25 mm; R4 > 100 mm) of Masson pine (Pinus massoniana) stump syste...
