objective: the objective of this study was to investigate the invitro fluoride release of four new self-adhesive resin cements; set (sdi, australia), breeze (pentron, usa), embrace wetbond (pulpdent, usa), g-cem (gc, japan) and to assess the bonding performance of these self-adhesive resin cements for bonding of orthodontic brackets. materials and methods: for fluoride release experiment, six ...
introduction membrane bioreactor (mbr) is an effective technology for wastewater treatment and water reuse which is becoming increasingly popular due to its numerous applications and advantages over conventional activated sludge process. this novel technology have advantages of small footprint, high concentration of mixed liquor suspended solids (mlss), high removal efficiency of chemical oxyge...
the effect of salinity on growth, inorganic ions and dry matter partitioning in sugar beet cultivars
this study investigated intra-specific variation in the growth parameters and dry mat-ter partitioning of sugar beet cultivars at different levels of salinity (0, 50, 150, 250 and 350 mm nacl + cacl2 in 5:1 molar ratio) using four cvs, one british (madison) and three iranian cvs (7233-p12, 7233-p21 and 7233-p29). the plants were grown in a controlled greenhouse environment for about 18 weeks. a...
in this research, a sol-modified composite electrodeposition technique that combines the sol-gel method with the conventional electrodeposition process was utilized to deposit ni-tio2 nanocomposite coatings. cyclic voltammetry and chronoamperometry techniques were applied to study the influence of the tio2 sol concentration on the deposits’ electrochemical behavior. the results clearly showed t...
Long-term investigations carried out in a submerged membrane fungi reactor treating textile wastewater revealed the excellent fouling prevention capacity of spacer-filled hollow-fiber modules. The type and arrangement of the spacers governed the overall rigidity of the modules and played the critical role in avoidance of sludge intrusion and retrieval of the original state (cleaning). A hybrid ...
We evaluate the mRNA expression of monocarboxylate transporters 1 and 4 (MCT1 and MCT4) in skeletal muscle (soleus, red and white gastrocnemius), heart and liver tissues in mice submitted to a single bout of swimming exercise at the maximal lactate steady state workload (MLSSw). After 72 h of MLSS test, the animals were submitted to a swimming exercise session for 25 min at individual MLSSw. Ti...
