A steel shear modulus measurement has been conducted using spring-mass oscillation analysis. The purpose of this study is to determine whether the spring-mass oscillation analysis method can measure the shear modulus of the steel. In this study, springs that are used are made of steel with a spring radius of 7.86 mm, a spring wire diameter of 0.817 mm and there is no distance between the coil springs. The length of the spring is varied 7 times, i.e., 4.75 cm, 5.36 cm, 5.89 cm, 6.81 cm, 8.53 cm, 9.44 cm, and 10.87 cm. The spring radius and the diameter of the spring wire are measured using a micrometer screw, while the spring length is determined using image analysis using the Logger Pro program. The spring constant is determined from the equation of the results of the position graph fitting (x) with respect to time (t) load on the oscillating spring-mass system. The value of the shear modulus can be determined from the constants on the graph of the relationship of the spring constant to the spring length following the equation from Sommerfeld. The research measures the shear modulus is 1.24 GPa

The Relationship

In this paper the dynamic property (shear modulus and damping ratio) of cement-stabilized soil is studied with using the resonant column test. The amount of cement admixed, the magnitude of confining pressure, and shearing strain amplitude are the parameters considered. Test results show that the maximum shear modulus of cement-stabilized soil increases with increasing confining pressure, the minimum damping ratio decreases with increasing confining pressure. The shear modulus of cement-stabilized soil decreases with increasing shearing strain while the damping ratio increases with increasing shearing strain. In the paper the relationship of shear modulus versus shearing strain is fitted into the Ramberg-Osgood equations using regression analysis.

This study aims to find out the relationship of readability over financial reporting footnotes and audit outcomes. Audit outcomes are projected by audit fees and audit report lag.  Researchers used data from the company's financial statements listed on IDX in 2015-2018. Researchers used purposive sampling. From the copying, researchers processed 184 company data. This study used the panel's data regression analysis method. Data processing uses Generalized - least - squares.  This research proves that the worse the readability, the lower the audit fee.  Meanwhile, the worse the readability, the more time it takes the auditor to carry out an examination of the financial statements. This phenomenon occurs because the condition of the readability of notes to financial statements in Indonesia is still at a low level.

Abstract Religious behavior student become a benchmark for the success of learning, especially learning Islam. Where the results of learning Islamic education not only from the aspect of cognitive but also affective and psychomotor aspects. Therefore, it is very interesting to do research if there is a relationship between religious behavior with Islamic education learning outcomes. The purpose of this study was to determine whether or not the relationship of religious behavior with Islamic education learning outcomes . The method used in this research is descriptive analysis method with quantitative research forms. The results showed no relationship between religious behavior with Islamic education learning outcomes. This conclusion is based on the correlation test was done using the formula Kendal tau test with SPSS. The test results show significant figures 0548> 0.05. Shown significant values greater than 0.05 means that there is a relationship between religious behavior of students with the learning outcomes of Islamic Education in SMA Negeri 1 Ambarawa Pringsewu.

Maximum Amplification

The finite difference program FLAC is used for dynamic modelling of slopes whereby the relationship of the slope geometry, earthquake input signals (mainly frequency of the wave) and the material properties with amplification of vibration on the surface are investigated. At the same time, the influence of varying input frequencies is also investigated. The higher slopes were amplified most by the lower input frequency whereas the reverse was true for the smaller slopes. The overall magnitude of the amplification was maximum with input signals of higher frequency and lower slope heights. The horizontal amplification as much as 17 (horizontal acceleration in the order of 1.7g) was obtained for the normal limestone slope with 20 m height when an input signal of 15 Hz frequency was applied. This experiment revealed that for extremely lower values of shear modulus, there was mostly attenuation instead of amplification and for extremely high values of shear modulus, amplification was negligible as compared to the certain range of intermediate shear modulus. Maximum amplification in the order of 6.5 (horizontal acceleration of 0.66g) was achieved for the shear modulus of 3000 MPa where slope height was of 40 m.   doi: 10.3126/bdg.v12i0.2253 Bulletin of the Department of Geology, Vol. 12, 2009, pp. 88-94

This study aims to investigate the vector direction of the relationship between agriculture performance, employment in agriculture, and education in Indonesia. This research uses the vector analysis method. where the dependent variable and the independent variable take turns to see the direction of the relationship of each variable to each other. All data used in this study are sourced from the world bank data. We found that labor absorption in the agricultural sector in Indonesia continues to decline very sharply, it becomes a threat to agriculture performance in the future. Because there is a decline in performance in the future due to labor shortages and it is possible that the agricultural sector will be completely destroyed when there is a shortage of labor in this sector if the interest of the Indonesian youth in the agricultural sector is not invested.

AbstractThe development of a multifunctional, micron-scaled, reticulated copper foam that reliably exhibits high intrinsic thermal conductivity, efficient capillary fluid and evaporative transport over a wide area presents a unique challenge. In this work, the relationship of critical foam processing variables such as sintering temperature and template size on the pore size distribution and pore neck/body ratio is investigated using image analysis. The resulting fluid permeability values of these foams are estimated by using the Kozeny Carman equation and the porosity, surface area per unit area and tortuosity obtained through image analysis. Estimating the fluid permeability of these foams is useful for predicting the mass and heat transfer within the porous network, and provides a metric for optimizing the foam’s structural characteristics for a particular application.

In this study, the author collaboration network is established by taking the national social science fund papers in the field of intelligence science included in CSSCI as the data source and the paper collaboration relationship of high-yielding authors as the research object. The connection structure and influence of nodes in the network are analyzed by using the Ego-network analysis method, and the network size, intensity, density of high-yielding author ego-network and the relationship with the influence of academic influence of researchers are found out. Measures of academic influence were also validated analytically. The size of collaboration network and the strength of connection between network members of researchers are positively correlated with academic influence, and there is an inverted U-shaped relationship between network density and academic influence. Finally, this study proposes suggestions on how researchers can strengthen academic collaboration to enhance academic influence.
