THEORETICAL COMPLEX ENERGIES OF STARK RESONANCES IN LITHIUM BY OPERATOR PERTURBATION THEORY APPROACH

The theoretical complex energies of the Stark resonances in the lithium atom (non-hydrogenic atomic system) in a DC electric are calculated within the operator form of the modified perturbation theory for the non-H atomic systems. The method includes the physically reasonable distorted-waves approximation in the frame of the formally exact quantum-mechanical procedure. The calculated Stark resonances energies and widths in the lithium atom are calculated and compared with results of calculations on the basis of the method of complex eigenvalue Schrödinger equation by Themelis-Nicolaides, the complex absorbing potential method by Sahoo-Ho and the B-spline-based coordinate rotation method approach by Hui-Yan Meng et al.

Construction and Validation of Occupational Stress Scale for Public Prosecutors

Occupational stress has the adverse effects on personal and work-related life of workers. Public prosecutors experience specific stressors at work, but no scale has yet been designed to measure occupational stress among public prosecutors. The present study was carried out to construct and validate an indigenous Occupational Stress Scale for Public Prosecutors in Pakistan. An inductive approach was used for item generation. After ensuring the construct fidelity and content validity: the items of the scale were subjected to principal axis factoring, using a varimax rotation method on a sample of 416 public prosecutors and 32 items were retained in a well-defined 5 factor structure, which collectively accounted for 54.39 percent of the variance. Moreover, a confirmatory factor analysis on a sample of 350 public prosecutors was performed through AMOS modeling and the final scale consisted of 26 items was obtained. The relationship of scale with job satisfaction was found to be the negative (r = -.30, p<.01) that determined its divergent validity. Furthermore, the relationship of the scale with Health and Safety Executive Management Standard Indicator Tool was found to be the positive (r = .52, p<.01) that determined its convergent validity. The final scale is a promising measure with good items homogeneity, internal consistency and optimum validity

Evaluation of Curved Canal Transportation Using the Neoniti Rotary System with Reciprocal Motion: A Comparative Study

The ideal root canal preparation is where the original canal morphology is maintained during the biomechanical preparation. Preparation of curved canals has always been a challenge to clinicians. Better results have been suggested for a single NiTi instrument with reciprocating motion than the conventional continuous rotation method in the preparation of curved root canals. Although the Neoniti rotary system is not suggested to be used with reciprocal motion, running a pilot study, we found that it could be possible. The present study aimed to investigate if shaping curved canals using the Neoniti rotary system with reciprocal motion leads to better results in terms of root canal transportation. One hundred acrylic j-shape canal simulator endoblocks were used in this study. Five preparation sequences were applied: GPS followed by A1#20 (GPS + A1#20), GPS followed by A1#20 and then A1#25 (GPS + A1#20 + A1#25), GPS followed by A1#25 (GPS + A1#25), hand file followed by A1#20 (hand file + A1#20), and GPS followed by A1#20 (with reciprocal motion) (GPS + A1#20(reciprocal)). Pictures were taken from blocks once before and once after preparation from two dimensions. Before-and-after pictures were superimposed in Photoshop software. Measurements were performed in Digimizer. The number of autoreverses and pecking motions was recorded after reviewing the recorded videos. Data were analyzed in SPSS, version 26. A p value of less than 0.05 was considered statistically significant. The group GPS + A1#20 + A1#25 had more transportation compared with the others, at apical, middle, and coronal thirds not only in the frontal view but also in the lateral view. Other groups were not significantly different. The number of peckings and autoreverses was significantly less when A1#25 was used after GPS and A1#20. When A1#20 was used with reciprocal motion, it had less peckings compared with the same file with continuous rotation, and no autoreverses were observed in that group. Using Neoniti files with reciprocal motion might result in less instrument fatigue and favorable results, with respect to canal anatomy preservation. Using A1#20 before A1#25 also will decrease the stress on the instrument during preparation. However, this may lead to significantly more canal transportation.

Ground Moving Target Imaging for Highly Squint SAR by Modified Minimum Entropy Algorithm and Spectrum Rotation

Ground moving target (GMT) is displaced and defocused in conventional synthetic aperture radar (SAR) image due to the residual phase error of non-cooperative GMT motion. In this study, a GMT imaging (GMTIm) method is proposed for highly squint SAR. As the squint angle become large, the displace and defocus effect of the GMT image become severe and the geometry distortion of the GMT image cannot be ignored. The proposed method first deduced the two-dimensional (2-D) frequency domain signal of the GMT and the bulk compression function of the Range Migration Algorithm (RMA) in highly squint SAR. Then GMT ROI data are extracted and a modified minimum entropy algorithm (MMEA) is proposed to refocus the GMT image. MMEA introduces the idea of bisection into the iteration process to converge more efficiently than the previous minimum entropy method. To overcome the geometry distortion of the GMT image, an equivalent squint angle spectrum rotation method is proposed. Finally, to suppress the GMT image sidelobe, the sparse characteristic of GMT is considered and a sparse enhancement method is adopted. The proposed method can realize GMTIm in highly squint SAR where the squint angle reaches to 75 degrees. The PSNR and ISLR of point target in highly squint SAR is close to that in side-looking SAR. The simulated point target data and ship data are used to validate the effectiveness of the proposed method.

Development and Validation of Perceived Inter-Parental Conflict Scale for Adolescents

The study aimed to develop a culturally relevant scale to assess the perceived inter-parental conflicts in adolescents by using a mixed-method approach. Semi-structured in-depth interviews with 10 adolescents of age range 14-18 years were conducted along with 3 focus groups of parents and teachers that helped to generate a pool of 88 items. Construct validity and psychometric properties were determined on a sample of 500 adolescent with age range 14-18 years (M = 15.28, SD = 1.07). Principal axis factoring through direct oblimin rotation method postulated 60 items with six distinct factors (named as overt conflicts, familial conflicts, conflicts related emotional reactivity, financial conflicts, child related conflicts, and psychological conflicts) that accounted for 38% variance. The Cronbach’s alpha coefficient for total scale was .94 and ranged from .63 to .92 for six emerged factors. The convergent and discriminant validity of the scale was also satisfactory. Perceived Inter-Parental Conflict Scale for Adolescents (PIPCSA) was a reliable and valid measure to assess perceived inter-parental conflicts in adolescents.

DEVELOPMENT AND CONSTRUCT VALIDATION OF QUESTIONNAIRE ASSESSING THE ADULT IMMUNISATION PERCEPTIONS AMONG MALAYSIAN POPULATION

Introduction: Immunisations are one of the most effective public health interventions, reducing or eliminating the burden of many infectious diseases. This study aims to establish the construct validity of a newly developed adult immunisation perceptions questionnaire among Malaysians. Methods: The Adult Immunisation Perceptions-Questionnaire (AIP-Q) was created following literature reviews on The Health Belief Model. Primarily, 64 questions were pooled, followed by face validity by experts, pretested via 20 healthcare personnel and later translate into the Malay language. A total of 305 respondents were selected for the construct validation process. Varimax rotation method used in the analysis for exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) done using AMOS software. Results: Ten constructs were produced as predicted in EFA: health believes, experience, knowledge, attitude, perceived severity, perceived susceptibility, perceived benefits, perceived barriers, and 2 cues for action. Thirteen items with low factor loading and unrelated to the recovered domains were removed from being included in CFA. In path analysis, the scale fitted ?2/df=1.943 (n=305) =p<0.001, CFI=0.908, IFI=0.909, TLI=0.901 and RMSEA=0.056. Strong factor loading was found across the final items, ranged from 0.53 to 0.94 with a good reliability test (Cronbach Alpha, AVE and CR values) for all constructs. Conclusion: The final AIP-Q consists of 10 domains with 45 items that give a promising psychometric property. This questionnaire can measure the perceptions of adult immunisation among the Malaysian population and can be utilized for the nationwide study.

Separation of Split Shear Waves in Two Non-orthogonal Sets of Vertical Fractures

The phenomenon of S-wave splitting indicates the development of fractures in the shallow crust. Therefore, methods based on S-wave splitting have been established to predict the development of one set of parallel fractures. However, for rocks containing two non-orthogonal sets of vertical fractures, the mechanism of S-wave splitting is more complex, and the available methods cannot be applied. To resolve this inadequacy, we propose a two-way rotation method to separate split S-waves with the aim of restoring the split S-wave polarizations and predicting the fracture azimuths. First, we calculate the stiffness matrix of fractured media based on the linear slip theory and derive the phase velocities and polarizations of split S-waves induced by fractures using the Christoffel equation. Second, we clarify the S-wave splitting mechanism in this media by employing velocity analysis and deconstruct the S-wave polarizations on the horizontal components. Third, we deduce a two-way rotation matrix obtained by the S-wave splitting modes to separate the split S-waves. To solve for the angle parameters related to the fracture azimuths in the two-way rotation matrix, we superpose the subspace polarizations in two dimensions to determine the polarization azimuths of the split S-waves. Numerical model tests demonstrate that the proposed method is stable under noisy conditions. Finally, we apply the proposed method to real near-offset and walkaround VSP data, and the predicted fracture results are verified by imaging logs and prior knowledge.
