Although Mount Penanggungan is not active, it still make an interesting investigation in geological survey, especially to identify the lithological units, due that less researchers took place in Mount Penanggungan. Geological survey and investigaton can describes the information about physically condition of some land or region, with the result is Lithological Map of Mount Penanggungan. Remote sensing imagery, such as Landsat 8 Satellite imagery data series has been used widely in geology for mapping lithology in general. Remote sensing provides information of the properties of the surface exploration targets that is potential in mapping lithological units. Remote sensing technique are one of the standard procedures in exploration geology, due to it is high efficiency and low cost. Lithological mapping in Mount Penanggungan area is carried out by using Landsat 8 Satellite imagery data with image enhancement techniques, including RGB (red, green, blue) band composite, and combine it with Indonesian Surface Map data that will makes an existing Lithological Map of Mount Penanggungan. The results of this study showed the distribution of the lithological units in Mount Penanggungan, which the units are; vulcanic breccia, tuff breccia, and andesitic lava

Visualizing the Quantum Interaction Picture in Phase Space

We illustrate the correspondence between the quantum Interaction Picture-evolution of the state of a quantum system in Hilbert space and a combination of local and global transformations of its Wigner function in phase space. To this aim, we consider the time-evolution of a quantized harmonic oscillator driven by both a linear and a quadratic (in terms of bosonic creation and annihilation operators) potentials and employ the Magnus series to derive the exact form of the time-evolution operator. In this case, the Interaction Picture corresponds to a local transformation of phase space-reference frame into the one that is co-moving with the Wigner function.Comment: Submitted to New Journal of Physic

Universal behavior of localization of residue fluctuations in globular proteins

Localization properties of residue fluctuations in globular proteins are studied theoretically by using the Gaussian network model. Participation ratio for each residue fluctuation mode is calculated. It is found that the relationship between participation ratio and frequency is similar for all globular proteins, indicating a universal behavior in spite of their different size, shape, and architecture.Comment: 4 pages, 3 figures.

Experimental investigation of minimum quantity lubrication in meso-scale milling with varying tool diameter

Minimum quantity lubrication (MQL) is a method that uses a very small amount of liquid to reduce friction between cutting tool and work piece during machining. The implementation of MQL machining has become a viable alternative to flood cooling machining and dry machining. The overall performance has been evaluated during meso-scale milling of mild steel using different diameter milling cutters. Experiments have been conducted under two different lubrication condition: dry and MQL with variable cutting parameters. The tool wear and its surface roughness, machined surfaces microstructure and surface roughness were observed for both conditions. It was found from the results that MQL produced better results compared to dry machining. The 0.5 mm tool has been selected as the most optimum tool diameter to be used with the lowest surface roughness as well as the least flank wear generation. For the workpiece, it was observed that the cutting temperature possesses crucial effect on the microstructure and the surface roughness of the machined surface and bigger diameter tool actually resulted in higher surface roughness. The poor conductivity of the cutting tool may be one of reasons behind

Measurement Invariance of the Internet Addiction Test Among Hong Kong, Japanese, and Malaysian Adolescents

There has been increased research examining the psychometric properties on the Internet Addiction Test across different ages and populations. This population-based study examined the psychometric properties using Confirmatory Factory Analysis and measurement invariance using Item Response Theory (IRT) of the IAT in adolescents from three Asian countries. In the Asian Adolescent Risk Behavior Survey (AARBS), 2,535 secondary school students (55.91% girls) in Grade 7 to Grade 13 (Mean age = 15.61 years; SD=1.56) from Hong Kong (n=844), Japan (n=744), and Malaysia (n=947) completed a survey on their Internet use that incorporated the IAT scale. A nested hierarchy of hypotheses concerning IAT cross-country invariance was tested using multi-group confirmatory factor analysis. Replicating past finding in Hong Kong adolescents, the construct of IAT is best represented by a second-order three-factor structure in Malaysian and Japanese adolescents. Configural, metric, scalar, and partial strict factorial invariance was established across the three samples. No cross-country differences on Internet addiction were detected at latent mean level. This study provided empirical support to the IAT as a reliable and factorially stable instrument, and valid to be used across Asian adolescent populations

The Correlation Between Level of C-Reactive Protein and Radiographic Grading of Knee Osteoarthritis

Introductions. Several studies have shown that the acute phase response may take place in osteoarthritis, suggesting that low grade systemic inflammation may be present in patients with osteoarthritis. Materials and methods. This study was aimed to measure the c-reactive protein level of knee osteoarthritis, to determine radiographic grading of knee osteoarthritis according to Kellgren-Lawrence grading, and to determine correlation between level of c-reactive protein and radiographic grading of knee osteoarthritis. This study used observational cross sectional design. Samples were 65 postmenopausal women with clinical knee osteoarthritis, aged 50 to 70 years old. Clinical and radiologic diagnoses of knee osteoarthritis were determined by clinical and radiographic examination with AP weight bearing position. Grade <3, grade 3 and grade 4 were radiographic grading of knee osteoarthritis according to Kellgren-Lawrence classification. Results. From 65 samples, 28 (43%) samples had grade < 3 with level of c-reactive protein 0.2-1.0 mg/dl (0.54±0.23 mg/dl), 22 (34%) samples had grade 3 with level of c-reactive protein 0.3-1.4 mg/dl (0.70±0.33 mg/dl) and 15 (23%) samples had grade 4 with level of c-reactive protein 0.3 -1.3 mg/dl (0.80±0.26 mg/dl). The cumulative of level of c-reactive protein was 0.2-1.4 mg/dl (0.65±0.29 mg/dl). There is correlation between level of c-reactive protein and radiographic grading of knee osteoarthritis (p=0.04), with Spearman rho correlation of 0.349 and α=5%. The level of c-reactive protein in grade <3, grade 3 and grade 4 overlaps, so the level of c-reactive protein could not be used to determine radiographic grading of knee osteoarthritis. Conclusions. There is no correlation between level of c-reactive protein and radiographic grading of knee osteoarthritis, there is a tendency that the level of c-reactive protein is higher in high grade knee osteoarthritis

Pectobacterium atrosepticum biosensor for monitoring blackleg and soft rot disease of potato

Pectobacterium atrosepticum (Pba) is a quarantine and threatening phytopathogen known as the causal agent of blackleg and soft rot disease of potatoes in many areas. Its early detection is then important to have healthy potato tubers and reduce economic losses. Today, conventional methods such as enzyme-linked immunosorbent-assay (ELISA) and polymerase chain reaction (PCR) are typically used for Pba detection, but they are expensive and time-consuming. Here we report on the optimization of an alternative approach based on an electrochemical impedance immunosensor combining a microfluidic module and a microelectrodes array, and having advantages in terms of low cost, ease of use and portability. For validation and for assessing its performance, the lab-on-chip platform has been compared with two standard methods (ELISA and PCR)

The amount of standardised mean difference (SMD) was equal to -0.3 with a %95 confidence interval of -0.82 to 0.23 for rTMS-treated group versus sham group with a substantial rate and significant heterogeneity (P < 0.001, I-Squared = 81.9%). Conclusion: Repetitive Transcranial Magnetic Stimulation is a method with significant and high safety. On other side, its efficacy, compared to sham group, is not very significant. © 2015, Isfahan University of Medical Sciences(IUMS). All rights reserved

Chromogenic in situ hybridisation test for breast cancer patients with equivocal IHC results - A study from Iran

Background: HER2/neu overexpression on cell membranes of breast cancer cells is due to HER2/neu gene amplification and it is important to identify potential candidates for anti HER2 therapy with trastuzumab. IHC, FISH and CISH are standard FDA approved assays currently used to determine HER2 status in routine practice. The aim of this study was to determine HER2 gene amplification, using the CISH method in breast carcinoma samples which had IHC +2 reactions. Materials and Methods: This study was conducted from 2008-2010 using 334 consecutive breast carcinoma samples referred from local laboratories to Mehr Hospital. CISH assays were performed for all cases, and IHC tests were also done for determining efficacy and accuracy of local labs. HER2 status in local IHC tests was compared with central IHC and CISH results. Results: Of 334 breast cancer patients, 16 were negative for HER2 IHC (0, +1), 201 cases were equivocal (+2), and 31 positive (+3). Of 334 referral cases, 88 were CISH positive (26.3) and 246 were CISH negative (73.7). Of 201 IHC +2 cases, HER2 gene amplification was observed in 42 cases (kappa: 0.42). A 29.9 concordance was found between local IHC and central IHC. Sensitivity and specificity of local IHC were 90 and 53.8, respectively. Conclusions: Low accuracy of IHC results in local labs was associated with the following factors: using former FDA-approved criteria for HER2 interpretation, utilizing non-validated kits, and lack of any quality assurance program. Therefore, following the new 2014 ASCO/CAP guideline and comprehensive quality assurance should be implemented to ensure accuracy of HER2 testing
