In vitro results showed that UV-C treatment not only improved the cell spreading and attachment, but also it made the cells more metabolically active. UV-C effectively removed the hydrocarbon contaminants and exposed the TiO2 on the surface, which is a good indication for higher and faster bone-to-implant contact than hydrocarbon-coated implants. Larsson et al. (1996) showed that high degrees of bone contact and bone formation were achieved with titanium implants which were modified on oxide thickness. On the other hand, Aita et al. (2009) revealed that UV-induced biological effects could be obtained even on the surfaces of titanium dioxide bulks without depositing additional oxidative titanium or sintering.
Ellipsometry, as a thin film characterization technique, was selected because it is non-invasive, non-destructive, non-contacting, and can allow the user to determine several film properties simultaneously (Woollam JA, Snyder PG 1990; Vedam K 1998). Based on this, the tested samples did not undergo any surface modifications by this device. Also, all the work for the crucial thickness measurements (ellipsometry) and the UV-C illumination (light source) was done in a HEPA-filter-protected Clean Room. The total number of particles available for adsorption (in the background) were fewer than 100 condensation nuclei / cc, which met clean room standards for NASA class-100 (Clean Room Fact Sheet, NASA 2016). The measured refractive index (R.I) for the baseline commercially
The ways in which we learn and understand the world come from the ways we receive information and how we choose to exist in the world. In Six Degrees of Separation, Paul forces his way into the lives of upper class white families and reveals the hegemonic social stratifications that dominate their lives. The literary point of view, how the story is revealed, is significantly different in the film adaptation to concentrate on the systemic ways people create relationships with each other and how race, gender, sexuality, and class actively drive the ways people are able to exist.
The film Mosquita y Mari directed and created by Aurora Guerrero is a coming of age story set about Huntington Park in the southeastern part of Los Angeles. It uses tense scenery that seeks to explore what it means to be in a romantic relationship versus a close friendship. Furthermore, upon legitimizing Yolanda and Mari`s relationship the film provokes the audience to ask the question, “If they are queer, what is keeping them in the closet?” This question is most effectively answered by examining how Yolanda and Mari`s ethnicity, locational, and immigrant descendant identities intersect to keep them in the closet.
The film, Latcho Drom, by Tony Gatlif follows the journey of the gypsies in a manner that presents an eruption of cultural difference to the audience the duration of the plot. Latcho Drom is a poetic tribute to the gypsy culture. The film produces a lens in which the audience looks at the world in an altered approach. The movie was shot in numerous countries retracing the significant path taken by the gypsies over time.

Metal had been recognized to be non-bioactive material, which has no osteoinductive and osteoconductive properties. However in the last few decades, numbers of publications have proven that metals like, titanium can become bioactive if it is treated properly. One typical way to increase osteobiological traits of metal is through refining the surface roughness [76]. Because materials interact with the biological environment through their surface, therefore controlling the surface topography is one
In recent years, advancements in the field of tissue engineering coupled with a growing demand from orthopedic medicine has led to the interlacing of these fields. This is most evident in the area of development or betterment of orthopedic implants. The needs and uses for orthopedic implants vary, but generally these implants are designed to replace, repair, or support a damaged bone or joint, or to fix a deformation. Specifically when developing a device to fix a medical bone issue, tissue engineering plays a crucial role. Because the implant will be going inside the body, a main area of concern is the biological characteristics of the material used, and how these will affect the compatibility between the implant and body. There has been various studies conducted that show a correlation between the biocompatibility of a material and osteoblast induction. Therefore, when engineering a material it is imperative to maximize the biocompatibility in order to induce osteoblast production, ultimately healing the damaged bone. This review
Bubble is a porcelain sculpture that is shaped like a bead of water. The body of this piece is a deep cerulean with gold lines imprinted in an irregular pattern on top of the bubble. The striking blue caught my attention and I wondered what message Ai WeiWei was trying to convey with this piece. It was originally installed outdoors and was meant to be viewed in a hands-on way. Back in imperial China, porcelain belonged to the rich and wealthy. Being intentionally made to the public, Bubble provokes discussion regarding the impact of wealth and glamour in today's society as the common man was able to interact with something that only the elite and rich could (Butler, Lauren.
The natural selection of titanium for implantation is determined by a combination of most favorable characteristics including immunity to corrosion, bio-compatibility, strength, low density and the capacity for joining with bone and other tissue, known as osseointegration. The mechanical and physical properties of titanium alloys combine to provide implants which are highly damage
The advantages of metallic alloys include a light-weight nature and strength and biocompatibility. Titanium is one of the strong metals that being used in bone engineering. It has the properties of low density and ductile. It has been used as phtocatalysis because of the functions of bactericidal effects, deodorization, decontamination [5]. Recently, the application of Titanium alloys are using as medical implement and serve the function of replacing of hard tissue--bones [6,
The thin blue line is a late 70s documentary that analyzes the murder case of the officer Robert Wood. The two prime suspects are Randall dale Adams that was found guilty and David Harris. As we can see in this documentary Errol Morris is trying to prove Randall Adams innocence by showing us persuasive evidence. The evidence that I found more persuasive were Randall Adams’s timeline, the stolen car and murder weapon, the milkshake found on the side of the road and Davis Harris background history.
Chemistry of Film Exposure and Development Film is composed of an acetate base coated with a photographic emulsion layer. The base supports the emulsion, which consists of small silver halide crystals suspended in gelatin. The crystals are Silver-Iodobromide (silver bromide with added silver iodide). (Earle L. Kitts)
Noblebright fantasy is fantasy with a thread of hope even in the darkest hour, with characters who strive to live.
These positive results could be explained by various biological events occurring during bone healing process, dependent on aspects such as primary stability of the implant, the surgical technique, the prosthetic load and the associated inflammatory response.(84)
Alloplasts are osteoconductive; i.e., they act as a scaffold and support new bone growth. But, they neither generate new bone nor induce new bone formation. Later, studies reported that the ceramic alloplast, bioactive glass, in addition to being osteoconductive, bonds directly to bone
Security window film makes the glass in your windows strong enough to withstand strong winds and flying debris. It offers effective protection against storms, and that strength offers other benefits as well. Window film is retrofit to your windows while they're in their frames. A skilled installer ensures the film blends perfectly with the glass with no bubbles or creases to detract from the appearance of your windows. Here's a look why you may want to add protective window film to your home security arsenal.
