Applications of X-Ray Holography

X-ray holography is widely used in material, biology, and industry fields due to its potential to measure the microstructure and dynamic change of objects. In this review, the principle of X-ray holography and the development of this technology in different application fields are systematically summarized and discussed. Through analyzing the advancement of X-ray sources and recording medium, the research and development direction of X-ray holography are prospected and the overview on current strategies of novel X-ray holography is presented. It is proved that X-ray holography, as a powerful nondestructive measurement method, can be applied to a wide range of objects.

SUGGESTIONS FOR BEHAVIOR-INTERVENTION DESIGN PRACTITIONERS: FROM BEHAVIOR CHANGE MOTIVATIONS FOR CHINESE AGED 18 TO 25

Using applications to change behaviors is a popular trend in recent years as mobiles are the easiest recording medium for users. However, few users can keep the behavior change for a long time. The aim of this study is to investigate motivations of keeping an application-tracked behavior change to provide effective and promote effective and targeted suggestions for application-tracked behavior intervention design practitioners and researchers. A 28-day self-report experiment and following “focus group” discussion have been conducted to detect the possible motivations. The results indicated 8 motivations which can affect maintaining behavior change: cooperation, competition, award, reminder and alarm, trust and willingness, relation with disease information and unplanned events. In addition, the results explore some motivations from negative data in applications or the cheating for good performance data behavior. At the same time, the study suggested the functions needed in future behavior change applications.

Comparative Evaluation of Lateral Condylar Guidance Angle Measured Using Hanau’s Formula & Lateral Interocclusal Records

BACKGROUND The goal of registering condylar guidance is to program the articulator for simulating the patient’s condylar movements as accurately as possible to save chairside time involved in adjusting the occlusal interferences at the time of fit in. The use of Hanau’s formula (L = H / 8 +12) was advocated by Sir Rudolph Hanau in 1930 which he used to calculate lateral condylar guidance (LCG) for adjusting his articulators. But due to the ease of application, the formula is widely used by dentists till date. Jack Stern, Hanau's longterm partner, confided in 1960 that the 'Formula' was never considered to be precise, after 10 years of study (1920 - 1930). Rather it was a point of approximation. There is a lack of uniformity in the literature regarding average condylar inclinations and its comparison to the Hanau formula, therefore a study was undertaken to evaluate and compare the 2 methods used to determine the lateral condylar guidance. METHODS 24 completely dentulous participants were included in the study. Two methods were used to obtain the lateral condylar guidance, the first method was obtaining the calculated lateral condylar guidance using the hanau’s formula and the second was obtaining the measured lateral condylar guidance using the interocclusal records. Impressions of each participant were made. Protrusive and lateral records were made using interocclusal recording medium (MAARC® Perfect Bite Registration). After completion of facebow transfer, programming of the articulator was done using protrusive record and the horizontal condylar guidance was recorded. The calculated lateral condylar guidance was recorded using the Hanau’s formula & the measured condylar guidance was recorded using right and left lateral records. Both the values obtained were evaluated and compared. RESULTS Mean LCG values obtained using Hanau’s formula was 16 degrees for the left side (SD - 1.404) and for the right side it was 16.17 degrees. (SD - 1.694). Mean LCG values obtained using lateral interocclusal records were 20 degrees for the left side (SD - 6.691) and 20.08 degrees (SD - 4.926) for the right side.There was a statistically significant difference between lateral condylar guidance records obtained using Hanau’s formula and lateral interocclusal records. CONCLUSIONS Application of Hanau formula is helpful to estimate Bennett angle. No doubt the formula is easy to apply and less cumbersome, but when we are working on high precision demanding cases we should try and find better options to record LCG. Making a lateral interocclusal record and then programming the articulator is a more reliable method.

Proposal for a Data Size Saving Office System That Can Be Stored on a Floppy Disk

With the development of computer software and applications, various types of recording media have emerged and evolved. This is a result of the rapid increase in the amount of data created by computers and the constant demand for large-capacity storage media. As large-capacity recording media have become available at low prices, the number of content production without being aware of the data capacity is increasing. Rather, content production often contains unnecessary features and effects for personal use. In this research, we will examine the feasibility of a practical system by carefully selecting the functions required for general use without excessive modification of effects. A floppy disk is used as the recording medium to limit the data size of the system.

Film as Death

Chapter 3 focuses on The Act of Killing (Joshua Oppenheimer, Christine Cynn and anonymous), a film that opens up uncharted territory on which to recast the tenets of documentary, world cinema and filmmaking in general. It required the crew to put their lives at risk in the name of a project they hoped would change the way we experience cinema and reality with it. The film’s realist commitment emerges from where it is least expected, namely from Hollywood genres, such as the musical, the film noir and the western, which are used as documentary, or a fantasy realm where perpetrators can confess to their crimes without restraints or fear of punishment, but which retains the evidentiary weight of the recording medium.

Silencing and Sounding the Voice in Transition-Era French Cinema

This essay examines two contrasting aesthetics of the voice in early 1930s French cinema and the role that music played in each. Filmed theater, or théâtre filmé, emerged from the conception that sound cinema was primarily a recording medium. In French theatrical adaptations, the speaking voice took precedence over all other elements of the soundtrack. The author argues, however, that in théâtre filmé, speech takes on almost musical qualities, folding music and sound effects into the voice itself. Avant-garde filmmakers took a contrasting approach, rejecting the restriction of camera movement imposed by the theatrical model and hoping to recapture some of the visual freedom characteristic of silent cinema. These filmmakers told their stories with as little spoken dialogue as possible, incorporating music prominently into their soundtracks in order to silence the speaking voice. Though the intent may have been to strip the voice of its dominance within the soundtrack, these directors’ strategic denial of the voice often granted it a much greater significance. By examining early experiments with the voice on the soundtrack in the transition years—including those by Jean Renoir, René Clair, and Jean Grémillon—the author’s analysis expands the concept of “vococentrism,” as articulated by Michel Chion and David Neumeyer, to include different models of understanding the voice in cinema beyond those found in classical Hollywood and helps shed light on competing conceptions of the voice’s role in cinema before practices became codified.
