The aims of this study were to examine the effect of salts (CaCl2, CaSO4 and MgSO4) on the rheological and thermal properties of gelatin extracted from the skins of tropical fishes, sin croaker (Johnius dussumeiri) and shortfin scad (Decapterus macrosoma). It was found that the melting temperatures of fish skin gelatins were increased by 1.5 times as compared to bovine gelatin which was only in...

BACKGROUND Blood presence in apical surgery can prevent the correct vision of the surgical field, change the physical properties of filling materials and reduce their sealing ability. OBJECTIVES To describe which are the most effective and safest haemostatic agents to control bleeding in patients undergoing apical surgery. MATERIAL AND METHODS We carried out a systematic review, using Medli...

The object of the study was river water, which sampled 500 m before and after point discharge wastewaters from industrial activities. concentration chlorides, magnesium, calcium in all studied samples below value acceptable limit concentration. pH water sulphate were within limits. iron, ammonium, nitrite higher than limit. It suggested that pollution with iron mainly due to natural processes, ...

Monitoring the condition of building structures based on composite materials in aggressive environments shows that deterioration basic properties occurs under influence various factors such as temperature and humidity changes, addition to changes chemical composition air environment. In addition, during operation must retain not only mechanical laid down at design stage, but also electro-physic...

Aim: To evaluate the efficacy of bioglass (BAG-S53P4) in the treatment of patients with chronic osteomyelitis and compare the results with calcium sulphate antibiotic beads in one medical centre. Methods: Retrospective analysis of 25 cases. INCLUSION CRITERIA patients diagnosed clinically and radiographically of osteomyelitis and treated surgically (Group 1: cavitary bone defects treated with...

The purpose of this study was the dosimetric evaluation of thermoluminescent detectors of calcium sulphate doped with dysprosium (CaSO4:Dy) produced by IPEN compared to the TL response of lithium fluoride doped with magnesium and titanium (LiF:Mg,Ti) dosimeters and microdosimeters produced by Harshaw Chemical Company to clinical photon beams dosimetry (6 and 15 MV) using liquid water and PMMA p...

This paper studies the durability of Ultra High Performance Fibre Reinforced Concrete (UHPFRC) with high Blast Furnace Slag content (BFS) and nanoadditives such as crystalline admixture (CA), alumina nanofibres (ANF) cellulose nanocrystals (CNC), exposed to different aggressive environmental conditions: 1) three media: a) deionized water (dw), b) sulphate rich solution (ss) c) simulated geother...

Nocardia gypsoides, a species characterised by its ability to produce calcium sulphate granules, has been isolated for the first time from a corneal ulcer. In vivo this pseudomycete also forms gypsum. Every effort should be made to identify Actinomycetales to species level. The names Leptothrix and Streptothrix should be abandoned.
