When acoustic wave is incident on the underwater sound isolation materials, the materials produce dynamic stress or strain to transfer generating energy into heat energy.
So the materials play a role of vibration suppression and reducing radiation noise.

Grafting materials for major sinus lift C.
Ponta3 1University of Oradea, Faculty of Medicine and Pharmacy, Oradea, Romania 2 University of Agricultural Sciences and Veterinary Medicine, Faculty of Veterinary Medicine, Cluj-Napoca, Romania 3 Babes-Bolyai University, Faculty of Physics & Institute of Interdisciplinary Research in Bio-Nano-Sciences, Cluj-Napoca, Romania a ratiu_cristian@yahoo.com, b scavalu@rdslink.ro, Key words: Plasma Rich in Growth Factors, Equine bone, Porous titanium Abstract: The materials used for major sinus lift varies from autogenous or allogenous bone, to animal origin (xenograft) bone or synthetic (alloplastic) materials.
Disadvantages of using autogenous bone lead some authors to use bone substitution materials for sinus grafting [1].
Material and method The grafting materials used in tis study are equine bone ( by BIOTECK) and porous titanium (by Tigran -80% air and 20% pure titanium).
Conclusions The study presents a comparison between two clinical cases using different grafting materials.

Using Calcium Carbide Slag as one of Calcium-containing Raw Materials to Produce Cement Clinker Yali Wanga, Shijie Dongb, Linlin Liuc and Suping Cuid School of Materials Science and Engineering, Beijing University of Technology ,Beijing,100124,China awangyali1978@bjut.edu.cn, bdongshijie_rain@emails.bjut.edu.cn, clllydcg@emails.bjut.edu.cn, dcuisuping@bjut.edu.cn, Keywords: Calcium carbide slag, Limestone, Calcium raw material.
The quality requirements of calcium materials constituent CaO MgO f—SiO2（flint or quartz） SO3 Na2O+K2O content（%） ≥48 ≤3 ≤4 ≤1 ≤0.6 Mineral composition The XRD patterns of the natural limestone are shown in Figure 1.
Compared with limestone materials, calcium carbide slag has a higher content of CaO, less loss on ignition, a lower alkali content, higher sulfur and chlorine contents.
There are large differences in decomposition temperatures between the two raw materials.

Using XRF and SEM analyses, it was found that both materials showed high crystalinity.
However, it requires a lot of time and man power especially when raw materials require for pilot and commercial scale processes.

An innovative approach to the material science has demonstrated that photocatalytic activity may be conferred to cement-based construction materials, such as concrete, mortars, paints, etc.
Addition of photocatalytic materials to the RC structure during its construction phase could reduce the corrosion problem of RC materials.
Higher pH value of cementations materials in presence of mixed photocatalyst reduces the corrosion problem of RC materials.
