LCA-based indicators for recycling: a case study on plastic waste treatment in Flanders

Alexandros SfakianakisστοMedicine by Sfakianakis AlexandrosΠριν από 4 δευτερόλεπτα
The last decades, waste management strategies are shifting from waste disposal to recycling, considering waste as resources. To quantitatively monitor the progress in this transition, a wide range of indicators has been developed. One of these indicators developed by the European Commission is the recyclability benefit rate (RBR), defined as the ratio of the environmental benefits that can be achieved from recycling over the environmental losses related to virgin production and disposal. These environmental benefits and losses are expressed in terms of environmental impacts obtain... περισσότερα »

Addressing Saddle Nose Deformity

Alexandros SfakianakisστοHead and Neck Diseases by Alexandros G.SfakianakisΠριν από 4 ώρες
*To the Editor* Saddle nose deformity is one of the most complex cases that a rhinoplasty surgeon has to deal with. Surgery to address this deformity is tricky, with nasal airflow often being impaired in order to achieve a cosmetic improvement of the nose. When properly planned and executed, however, the outcome of surgery addressing saddle nose deformity can be quite rewarding for both the patient and the surgeon. from #Aesthetics via alexandrossfakianakis on Inoreader http://ift.tt/1lZTetq via IFTTT from #Med Blogs by Alexandros G.Sfakianakis via Alexandros G.Sfakianakis on Inore... περισσότερα »

*In Reply* We appreciate the kind words from Dr Xavier regarding our article and would like to elaborate on some of the statements in his letter. Dr Xavier comments on the Cakmak algorithm's type 4 deformity and suggests addressing these patients similarly to those with type 3a and type 3b deformities (using an L-strut affixed to holes drilled in the nasal bones), plus using a nonstructural graft, such as diced cartilage in fascia or diced cartilage with fibrin glue placed along the nasal dorsum, from the radix to the supratip area.

*Abstract* Purpose It is still unclear whether four, six, or more implants should be used when restoring fully edentulous maxillae. This research evaluated the in vitro screw torque loss of zirconia frameworks supported by six implants and cantilevered zirconia frameworks supported by four implants. Materials and Methods Computer aided design/computer-assisted machining was used to fabricate 10 one-piece frameworks. Standardized pressable porcelain crowns were fabricated and luted to the frameworks. Specimens were divided into two groups (n = 5): AO4, cantilevered 12-unit full-ar...περισσότερα »

Predictable Outcomes with Porcelain Laminate Veneers: A Clinical Report

Alexandros SfakianakisστοHead and Neck Diseases by Alexandros G.SfakianakisΠριν από 6 ώρες
Abstract This clinical report describes how to achieve predictable outcomes for anterior teeth esthetic restorations with porcelain laminate veneers by associating the digital planning and design of the restoration with interim restorations. The previous digital smile design of the restoration eliminates the communication barrier with the patient and assists the clinician throughout patient treatment. Interim restorations (diagnostic mock-ups) further enhance communication with the patient and prevent unnecessary tooth reduction for conservative tooth preparation.

Removal of cyanobacteria from synthetic and real water by dielectric barrier discharge process

Alexandros SfakianakisστοHead and Neck Diseases by Alexandros G.SfakianakisΠριν από 6 ώρες
Abstract The feasibility of cyanobacteria removal from freshwater by a dielectric barrier discharge (DBD) process is investigated. Seven commercial and environmental cyanobacteria strains, as well as real algae-laden water, were tested. The removal of the cyanobacteria was evaluated by analyzing the changes in chlorophyll *a* content, total organic carbon (TOC) concentration, and cell morphology. Nearly total removal of chlorophyll *a* was achieved within 20 min, while the TOC analysis exhibited an increase-decrease-increase trend in 60 min of treatment, likely due to the oxidatio... περισσότερα »

Removal of trihalomethane from chlorinated seawater using gamma radiation

Alexandros SfakianakisστοHead and Neck Diseases by Alexandros G.SfakianakisΠριν από 6 ώρες
Abstract Chlorine addition as a biocide in seawater results in the formation of chlorination by-products such as trihalomethanes (THMs). Removal of THMs is of importance as they are potential mutagenic and carcinogenic agents. In this context, a study was conducted that used ionizing radiation to remove THMs from chlorinated (1, 3, and 5 mg/L) seawater by applying various dosages (0.4–5.0 kGy) of gamma radiation. Bromoform (BF) showed a faster rate of degradation as compared to other halocarbons such as bromodichloromethane (BDCM) and dibromochloromethane (DBCM). In chlorine-dosed... περισσότερα »

Analysis of predictors related to soil contamination in recreational areas of Romania

Alexandros SfakianakisστοHead and Neck Diseases by Alexandros G.SfakianakisΠριν από 6 ώρες
Abstract Soil contamination in recreational areas can considerably affect children's health, as they are the segment of the population most sensitive to anthropogenic contamination. Soil contamination in recreational areas is influenced by a number of factors such as type and age of the recreational area, nearby traffic intensity, proximity to industrial areas, presence of vegetation, level of usage, treated wood structures, and the extent of maintenance operations carried out in the area. These can most often be observed during a simple site visit. The purpose of the present resea... περισσότερα »

Alexandros SfakianakisστοHead and Neck Diseases by Alexandros G.SfakianakisΠριν από 6 ώρες
*To the Editor* Saddle nose deformity is one of the most complex cases that a rhinoplasty surgeon has to deal with. Surgery to address this deformity is tricky, with nasal airflow often being impaired in order to achieve a cosmetic improvement of the nose. When properly planned and executed, however, the outcome of surgery addressing saddle nose deformity can be quite rewarding for both the patient and the surgeon. from #Aesthetics via alexandrossfakianakis on Inoreader http://ift.tt/1lZTetq via IFTTT from #Med Blogs by Alexandros G.Sfakianakis via Alexandros G.Sfakianakis on Inore... περισσότερα »

*In Reply* We appreciate the kind words from Dr Xavier regarding our article and would like to elaborate on some of the statements in his letter. Dr Xavier comments on the Cakmak algorithm's type 4 deformity and suggests addressing these patients similarly to those with type 3a and type 3b deformities (using an L-strut affixed to holes drilled in the nasal bones), plus using a nonstructural graft, such as diced cartilage in fascia or diced cartilage with fibrin glue placed along the nasal dorsum, from the radix to the supratip area. We would like to emphasize that our main goal in s... περισσότερα »

Effect of mold type, diameter, and uncured composite removal method on depth of cure

Alexandros SfakianakisστοHead and Neck Diseases by Alexandros G.SfakianakisΠριν από 6 ώρες
Abstract Objective This study compared the effects of mold material and diameter on the thickness of cured composite remnants and depth of cure (DOC) of resin-based composites (RBC). Material and methods One Polywave® curing light was used to photo-cure two shades of the same "bulk-fill" RBC in 4, 6, or 10-mm internal diameter metal or white Delrin® molds. For 60 specimens, the uncured RBC was manually scraped away as described in the ISO 4049 depth of cure test. The remaining 60 specimens were immersed in tetrahydrofuran for 48 hours in the dark. Maximum lengths of remaining har...περισσότερα »

*Abstract* Purpose It is still unclear whether four, six, or more implants should be used when restoring fully edentulous maxillae. This research evaluated the in vitro screw torque loss of zirconia frameworks supported by six implants and cantilevered zirconia frameworks supported by four implants. Materials and Methods Computer aided design/computer-assisted machining was used to fabricate 10 one-piece frameworks. Standardized pressable porcelain crowns were fabricated and luted to the frameworks. Specimens were divided into two groups (n = 5): AO4, cantilevered 12-unit full-ar...περισσότερα »

Predictable Outcomes with Porcelain Laminate Veneers: A Clinical Report

Alexandros SfakianakisστοHead and Neck Diseases by Alexandros G.SfakianakisΠριν από 6 ώρες
Abstract This clinical report describes how to achieve predictable outcomes for anterior teeth esthetic restorations with porcelain laminate veneers by associating the digital planning and design of the restoration with interim restorations. The previous digital smile design of the restoration eliminates the communication barrier with the patient and assists the clinician throughout patient treatment. Interim restorations (diagnostic mock-ups) further enhance communication with the patient and prevent unnecessary tooth reduction for conservative tooth preparation. Adequate communi... περισσότερα »
