We take attention into diadromous fish (salmon, trout, eel…) and their river migrations, and particularly, we focus on fishways, hydraulic structures that enable fish to overcome stream obstructions as dams or weirs.
Flume experiments were conducted in which the scour patterns around different representative forms of individual in-stream obstructions (solid cylinder, hexagonal array of circular cylinders, several forms of emergent and submerged vegetation) were monitored by means of a high-resolution laser scanner.
The results show that excess temperature caused by obstruction of stream flow was associated with the bubble clusters on the bore surface, which resulted in the creep deformation responsible for elongated grains and wall thinning.
Between the landslides that originated the obstruction of a stream bed there are no reported lateral spread cases in Italy.
While the mechanisms causing ventricular catheter shunt obstruction and down-stream shunt valve obstruction are likely multi-faceted, inflammatory cells certainly play a major role in shunt obstruction in pediatric and adult patients.
Affricate, also called semiplosive, a consonant sound that begins as a stop (sound with complete obstruction of the breath stream) and concludes with a fricative (sound with incomplete closure and a sound of friction).
AEs related to intravenous catheters: erythema and infiltration, fever, obstruction, externalisation and blood stream infection.
Major postoperative complications included major postoperative bleeding, bile leakage, bowel obstructions, severe infections such as blood stream infections and pneumonia, acute cholangitis, acute pancreatitis, cardiovascular events, and acute renal failure.
As the prostate enlarges, it can constrict the urethra, inducing various symptoms including a weak urinary stream, incomplete bladder emptying, nocturia, dysuria and bladder outlet obstruction [ 1, 2].
These reports suggest that obstruction of the upper lymphatic and hematogenous streams spreads cancer cells toward the anal region, thereby leading to anal metastasis.
