Abstract In order to achieve a high quality in the field of conservation of natural stone surfaces it is most important to realize a high penetration depth of the conserving fluids on the besis of extensive laboratory research on the application of conserving fluids the relation between important factors such as quantity absorbed, duration of application, penetration depth, and selected practical relevant conditions has been established. With these results it was possible to develop a computer program which is able to predict penetration depth for a random choise of practical conditions of application. By the option of the comparision of stored real and predicted values of penetration depth destructive tests on the object are quite superfluous.

This paper presents a predicted model of surface roughness of radial relief for resharpening end-mill. This model is constructed using a polynomial network. The major factors affecting grinding parameters are considered to be wheel spindle speed, feedrate, and grinding depth of cut. Experiments under specified conditions are deliberately designed and conducted to obtain the corresponding tested data for surface roughness that are used for training data of the proposed polynomial network. Consequently, a predicted model for surface roughness is established. Furthermore, a computer program in VB language is written based on this model. It can quickly calculate predicted values of surface roughness by simply inputting required cutting parameters. According to the experimental results, the developed polynomial network model shows high predicting capability on surface roughness of radial relief, and possesses promising potential in the application of predicting surface roughness in resharpening end-mill operation.

To obtain a high quality dental radiograph, it is advantageous to use 40 kiloelectron volt (kev) monochromatic radiation. The feasibility of obtaining this type of radiation by filtering rays of rare earth elements was studied by a computer program before experimentation. By use of 40 kev monochromatic radiation, skin exposure was reduced by a factor of two to three.

The research about seepage of RSA is little, but the material is familiar. There are many difficulties in laboratory research about the materials, so numerical simulation research in the paper is introduced. The model of the random structure about SRA is set up, and then the study of seepage is given. The conversion of the two boundaries is solved correctly in the computer program. So some conclusions are drawn that the rock blocks the seepage to some degree, and the changing of RSA seepage is little under the effect of the fluctuating of rainfall intensity, namely the changing of the seepage is less than the fluctuating of rainfall intensity. The study is the foundation of the next study about the coupled of stress and seepage of RSA.

Abstract The Andırap landslide is located on the left bank of the Kavşakbendi dam approximately 50 km from the Kozan district of Adana province in Turkey. After it was determined that the mass stability was impaired during the dam construction work, the landslide movements were followed by surface geodetic measurements and inclinometers. According to the measurements that were taken, displacements totaling 0.10 m were measured between 2010 and 2017, and it was determined that the speed of movement slowed considerably between 2017 and 2020. In this study, the results of stress-strain and stability analyses were evaluated taking into account the soil model created based on extensive site and laboratory research to examine the sliding mechanism of the Andırap landslide mass. After the numerical model was verified using site measurements, the movements of the landslide mass were examined by numerical analyses, taking into account the different loading conditions that may be encountered during the service life of the dam. According to the results of the analysis, no global slide was observed for the slip circle of the Andırap landslide and in the analyses conducted for the situation where the reservoir is full, the deep displacement of 0.11 m was consistent with the average displacement of 0.04 and 0.11 m deformation values measured from inclinometers. In the analyses carried out for the loading condition featuring a full reservoir and earthquake effects, it was calculated that shallow displacements reached up to 1.0 m, but deep displacements were 0.13 m.

Fish bone is a trash which has economic value that has not got much attention from both government and society. Although the researchers has examined much the beneft of the fsh bone in the laboratory, but it has not been socialized well. Terefore, social empowerment in transfer knowledge is necessary to be done, so the real beneft can be felt widely. Transfer knowledge about fsh bone waste manufacture to society becomes the study focus in UMT Terengganu. Te study was done in the factory of Lekor crackers by promoting participation. Te frst objective of the study is providing community care to the beneft of fsh bone as organic calcium which has high quality. Te second study of this research also seeks to provide learning to the society in manufacturing the fsh bone waste serve as hydroxyapatite. Te third objective is to provide transfer knowledge to society to make use of hydroxyapatite which comes from fsh bone waste to be consumed because it contains high nutrition namely calcium, phosphor and carbonate. Te fourth objective is for environment management so that it is free from pollution of fsh bone waste. Te approach used in this study is social engineering namely integrates between social and technology approaches of fsh bone waste manufacture which needs mechanic process. Social approach is needed to arouse community care of the beneft of participation in manufacture and the beneft of fsh bone waste in Lekor crackers area. Meanwhile, engineering approach is needed for the process of laboratory research towards fsh bone waste, and for the process of simplifcation fsh bone manufacture, so it can be adopted by society at large. Transfer knowledge about fsh bone waste manufacture to the society, it becomes study focus at UMT Terengganu. Te study was done in factory of Lekor crackers by promoting participation.

There are two widely used programs for plotting molecular structures for publication purposes: PLUTO [Motherwell (1970). University Chem. Lab., Cambridge, England] and ORTEP [Johnson (1965). Report ORNL-3794. Oak Ridge National Laboratory, Tennessee]. A program PLORTEP has been written which joins the best features of these two programs. PLUTO has an English-like set of instructions which are easy to learn and use, while ORTEP produces very high quality pictures.

Microwave imaging and defectoscopy are promising techniques for dielectric composite evaluation. Their most significant advantage is their relatively high penetration depth. Another feature worth noting is that traditional methods could not acquire an internal content with such a low impact on both the sample and surrounding environment, including the test operator, compared to other techniques. This paper presents microwave non-destructive and noninvasive methods for quality evaluation of layered composite materials using an open-ended waveguide probe. Pure |S11| parameters only exceptionally give a clear answer about the location of material cracks. Therefore, this makes it necessary to analyze these parameters simultaneously along with several other factors, such as stand-off distance, probe type or wave polarization. The purpose of the work was to find the dependency between the physical state of a layered composite powerplant pipeline and the S-matrix parameters response (reflection and transmission parameters) in a Ku frequency band that has not yet been extensively researched. Lower-frequency measurements broaden the application possibility for thicker composites, mainly because of a higher penetration depth and measurement setup availability. Different methods have been shown, including reflection and transmission/reflection methods, both in close proximity and in stand-off distance. The measurements are based on a low-complexity experimental setup.
