A review on high power SOFC electrolyte layer manufacturing using thermal spray and physical vapour deposition technologies

Manufacturing of solid oxide fuel cell （SOFC） components remains nowadays a key point for the indus- trial development of this technology. Especially, the deposition of the dense electrolyte layer which is sand- wiched between the porous anode and the porous cathode is of paramount importance and thus focuses a lot of attention. Therefore, this paper considers and reviews recent developments concerning solid electrolyte layers manufacturing using thermal spray （TS） and physical vapour deposition （PVD） technologies.

Influence of casein phosphopeptide-amorphous calcium phosphate application,smear layer removal,and storage time on resin-dentin bonding

The aim of this study is to evaluate the influence of Tooth Mousse (TM) application, smear layer removal, and storage time on resin-dentin microtensile bond strength (μTBS). Dentin specimens were divided into two groups: (1) smear layer covered; (2) smear layer removed using 15% EDTA for 90 s. In each group, half the specimens were treated once with TM for 60 min. After bonding procedures using a two-step self-etching adhesive (Clearfil SE Bond (CSE); Kuraray Medical, Tokyo, Japan), an all-in-one adhesive (G-Bond (GB); GC Corp, Tokyo, Japan), and a total-etch adhesive (Adper Single Bond 2 (SB); 3M ESPE, St. Paul, MN, USA), the specimens were stored for 3 d or 6 months in deionized water at 37 °C, and μTBS was tested and analyzed. With the exception of SB (no TM application) and GB, the μTBS was significantly increased for CSE and SB using EDTA pre-conditioning and 3 d of storage (P≤0.001). Bond strength of GB decreased significantly when using EDTA (3 d storage, P<0.05). TM application only increased the μTBS of GB (no EDTA) and SB (with EDTA) after 3 d (P≤0.02). Comparing the adhesives after 3 d of storage, CSE exhibited the greatest μTBS values followed by GB and SB (P≤0.02). The factors of adhesive, EDTA, and TM did not show any significant impact on μTBS when specimens were stored for 6 months (P>0.05). The additional application of TM and EDTA for cavity preparation seems only to have a short-term effect, and no influence on μTBS of dentin bonds after a period of 6 months.     

Vaginal lacerations from consensual intercourse in adolescents

Objective

(1) To describe lacerations of the vaginal fornices, an injury known to be associated with consensual sexual intercourse, including known complications and treatment course, (2) to contrast these injuries with injuries sustained during sexual assault, and (3) to discuss the assessment of adolescent patients for sexual injuries.

Methods

We present a case series of 4 female adolescent patients seen at a children's hospital over a period of 6 months. Each patient developed significant vaginal bleeding after sexual intercourse, and 3 of the patients presented to the emergency department with vital signs consistent with compensated shock.

Results

Each patient was evaluated by pediatric surgery, and found to have a laceration of the vagina. Three of the patients described consensual intercourse prior to the onset of bleeding, and had lacerations of the vaginal fornices; these patients were determined to have injuries resulting from consensual sexual intercourse. The fourth patient reported sexual assault as the cause of her injuries, and was treated for longitudinal lacerations of the vaginal wall.

Conclusions

Lacerations of the upper vagina are not frequently reported in forced vaginal intercourse, but are occasionally reported as injuries sustained during consensual coitus. In the absence of reported sexual assault, a severe vaginal fornix laceration is consistent with the diagnosis of coital injury from consensual intercourse. Diagnosis and treatment of this injury can be delayed due to the sensitive nature of these injuries. Bleeding can be profuse, leading to hemorrhagic shock, and these injuries may require transfusion of blood products and surgical repair in some cases. Complications may include hemoperitoneum, pneumoperitoneum, or retroperitoneal hematoma, even in the absence of complete vaginal perforation.

Practice implications

Knowledge of the consensual sexual injuries that may occur in adolescent patients can guide diagnosis, treatment, and counseling for the patient and her family, preventing long-term medical complications and legal consequences.     

Intellectual property and optimal copyright protection

Copyright protection, or more generally, intellectual property rights, can be regarded as a means for the stimulation of production of information goods. This paper analyses the basic problem of production and dissemination of information and the role of copyright protection as an incentive for the producers of creative works. Using a simple model, it is shown that not only a cause for limiting the extent of copyright protection does exist, but that also an argument for a minimum level of protection can be found. Even optimal copyright protection, given the restriction that production and dissemination of information goods has to be co-ordinated by a market mechanism, however, does not lead to a first-best (allocatively efficient) solution. Hence, the judgment that copyright protection is the best solution to the basic problem can be grounded only on a comparative institutional approach.Indeed, one has ample reason to despair of finding a legal tenet that governs the rights of authors and artists. There exists no legal principle by which the state is forced to grant to authors a right in their creation. They cannot claim any right thereupon. This is not to say that the state shall not award such a right. On the contrary, there is every reason to treat them like the most favoured workers, as they deliver a work that is more robust than ashlar, and bring food that does not decay...     

Institutional Struggles for Recognition in the Academic Field: The Case of University Departments in German Chemistry

This paper demonstrates how the application of New Public Management (NPM) and the accompanying rise of academic capitalism in allocating research funds in the German academic field have interacted with a change from federal pluralism to a more stratified system of universities and departments. From this change, a tendency to build cartel-like structures of allocating symbolic capital resulting in oligopolistic structures of appropriating research funds has emerged. This macro level structure is complemented by the strengthening of the traditional oligarchic structures of research, carried out by an increasing number of assistants under the direction of a professor on the meso level. The outcome of this institutional setting is a significant gap between the appropriation of research funds according to the allocation of symbolic capital and the production of knowledge in publications. The application of NPM therefore needs to be explained more as a result of the normative pressure of a globally established model of “rational” administration, and less as a result of its functional effectiveness. This is demonstrated by an empirical analysis with simple and multiple regressions using data on the allocation of research grants and publication records of German chemistry departments.     

Transferwirkungen künstlerischer Tätigkeiten. Ihre kritische Kommentierung durch eine umfassende Theorie ästhetischer Bildung

Transfer research examines how artistic activities can have an impact outside of the realm of art itself. The article concludes that this research can be carried out in a meaningful way, only within the framework of a comprehensive theory of aesthetic education. This theory would encompass the structural analysis of artistic activity, as well as biographical reports about artistic experiences. The elucidation of the concepts or themes relevant to the theory would include the notion of aesthetic experience, the understanding of immediate, aesthetic experiences, the analysis of artistic processes, and the outcomes of scientifically evaluated applications of aesthetic education.
