Sequential injection system (SI system) was used for the pretreatment of a carbon electrode in an anodic stripping voltammetry (ASV) for the determination of arsenic (III). In this research, a screen-printed carbon electrode (SPCE) was used; SPCE was prepared in our laboratory by us. In ASV, SPCE was chosen as a working electrode because SPCE is less expensive, easy to use for a flow cell and s...

Mononethanolamine (MEA)-based absorption-stripping for CO2 capture is studied. Energy demands in this process are dominated by the stripping column. The shortest stripping line distance approach is used to determine minimum energy requirements for the MEA stripping column under various lean loadings. Simultaneous reaction and vapor-liquid equilibrium is assumed and modeled by the direct incorpo...

Periosteal osteosarcoma is an extremely rare chondroblastic osteosarcoma in the flat bone. There were authors reporting of two cases of periosteal osteosarcoma in the highly unusual sites. One of them arose from the rib, in a 17-year-old male, which appeared as a hypodense juxtacortical mass with periosteal reaction on CT. The other one arose from the scapula, in a 17-year-old female, which sho...

During an osteological analysis of human skeletal remains from the site of Punta Lobos (Huarmey Valley, northern coastal Peru), an unusual erosive lesion of the cortex with periosteal reaction was observed on a right tibia. The authors undertook a review of paleopathological and medical literature to arrive at a differential diagnosis. The lesion is determined to be a non-malignant growth, poss...

Porous surface modified polyvinylidene ï‌‚uoride (PVDF) hollow fiber membranes are fabricated through a dry-wet phased inversion process. Surface modifying macromolecules (SMM) (1 wt. %) are used as additives in the spinning dope. The performance of the surface modified membrane in contactor application for CO2 stripping from water is assessed through the fabricated gas–liquid membrane contacto...

Increased mechanical loading of bone with the rat tibia four-point bending device stimulates bone formation on periosteal and endocortical surfaces. With long-term loading cell activity diminishes, and it has been reported that early gains in bone size may reverse. This study examined the time course for bone cellular and structural response after 6, 12, and 18 wk of loading at 1,200-1, 700 mic...

The determination of apparent nutrient digestibility and availability coefficients (ADC and AAC) of ingredients is an important process in the formulation of cost efficient diets for fish. Collection of feces by repeated manual stripping is commonly practiced. However, due to the stress and possible physical damage imposed on fish during repeated stripping, this practice may influence ADC and A...

It is well known that the periosteum is capable of bone formation. In the present study, the value of the vascularized periosteal graft in healing the long-bone defect filled with the allogenous bone graft was studied. The aim of the study was to verify the efficiency of the rotational vascularized periosteal graft as a optional surgical method as well as to prove its advantages in comparison w...
