SWKB and proper quantization conditions for translationally shape invariant potentials

Using a recently proposed classification for the primary translationally shape invariant potentials, we show that the exact quantization rule formulated by Ma and Xu is equivalent to the supersymmetric JWKB quantization condition. The energy levels for the two considered categories of shaped invariant potentials are also derived

Interpersonal Metafunction of Gender Talk in ELT Classrooms

In systemic functional approach to interpersonal metafunction, Halliday defines clause as a unit of exchange, with two main constituents called Mood and Residue. Mood (sometimes called Modal element) which is the main element of clause in process of meaning exchange realizes selection of mood in clause, and it is composed of Subject and Finite. Subject is invested with modal responsibility whereas finite realizes primary tense and modality. Drawing upon theoretical framework outlined above, present research explores interpersonal metafunction of gender talk in ELT classrooms. Objective is to determine different clausal structures (Declaratives, Integratives, Imperatives and Exclamatives) used by interlocutors with different genders using Azeri as their mother tongue, Farsi (Persian) and English as their second and foreign languages respectively. This research uses oral form of teacher-student interaction in classroom context as its corpus. About twelve hours of oral conversation between students and teachers from eight randomly selected classrooms are recorded and transcribed, resulting to 3288 clauses. Our findings show that dominant Mood used by both genders is declarative of third person simple present tense causing the process of meaning exchange to be one-sided and partial. Reconstructing clausal structures used by different genders in ELT classrooms may result into students’ high language proficiency in bilingual context of situation

Multi-sensor remote sensing analysis of coal fire induced land subsidence in Jharia Coalfields, Jharkhand, India

The subsidence in coal mines induced by surface and subsurface fires leading to roof collapse, infrastructure loss, and loss of lives is a prominent concern. In the study, satellite imagery from thermal and microwave remote sensing data is used to deduce the effect of coal fires on subsidence in the Jharia Coalfields, India. The Thermal Infrared data acquired from the Landsat-8 (band 10) is used to derive the temperature anomaly maps. Persistent Scatterer Interferometry analysis was performed on sixty Sentinel-1, C-band images, the results are corrected for atmospheric error using Generic Atmospheric Correction Online Service for InSAR (GACOS) atmospheric modelling data and decomposed into vertical displacement values to quantify subsidence. A zone-wise analysis of the hazard patterns in the coalfields was carried out. Coal fire maps, subsidence velocity maps, and land cover maps were integrated to investigate the impact of the hazards on the mines and their surroundings. Maximum subsidence of approximately 20 cm/yr. and temperature anomaly of up to 25 °C has been observed. The findings exhibit a strong positive correlation between the subsidence velocity and temperature anomaly in the study area. Kusunda, Keshalpur, and Bararee collieries are identified as the most critically affected zones. The subsidence phenomenon in some collieries is extending towards the settlements and transportation networks and needs urgent intervention. © 2021 The Author

Farā’id Alfāẓ al-Ḥayawānāt fī Al-Qur’ān Al-Karīm: Dirāsah fī al-I‘jāz al-Lugawi wa al-Bayāni

The Qur’an has many miraculous aspects, about which there has been much talk in the past and the present. It is related to the rhetorical and linguistic aspects, and this research comes as one of these episodes that reveal the secret of the uniqueness of the words of the Holy Qur’an in general and the uniqueness of its words in particular, which came in an unprecedented manner and was organized in a non-repetitive way between the folds of its verses, so it was distinguished and unique in that it was not repeated, even its root as well. So it was consistent with the splendor of its presentation and organized in its context, in a tight linguistic system from a wise expert, and to be specific, the research was limited only to the unique words of animals and insects that were mentioned in the entire Qur’an, using the integrative approach that mixes the historical method that traces the phenomenon to the origin of its origin, and from the first to launch it and use it through the times to what it has now settled, and the linguistic analytical method, which is useful in analyzing words linguistically to understand the meaning, then the descriptive method, which monitors the characteristics of the phenomenon and its features, then clarifying this uniqueness, its rhetorical effects, and its aesthetic value. Its graphic secret is a purely artistic work that falls under the artistic method. Accordingly, the study came in three main sections and a conclusion, accompanied by the sources and references of the research. The first of them: the definition of the uniques linguistically and idiomatically, the second: the uniqueness in the critical and rhetorical heritage, and the third: the uniqueness of animals and insects in the Qur’an. Perhaps with this we add a new twist to Qur’anic studies, in fulfillment of the Qur’an, and in enriching its language

Decision-Making in Fuzzy Environment: A Survey

Multi-criteria decision-making (MCDM) is a crucial process in many business and management applications. The final decision is based upon the relative weights to the decision-making team. The analytic hierarchy process (AHP) has found to be one of the most successful approaches for evaluations of the weights and the importance of the criteria. However, most of the evaluated values are not so precise due to the fuzziness of the evaluating environment. This chapter surveys essentially the basic analytic hierarchy process and the fuzzy analytic hierarchy process (FAHP). It depicts through an example the steps for using the original analytic hierarchy process for two levels of criteria. Then, it uses the same example to explain the fuzzy approach in the evaluation. Finally, it compares both approaches

Modification of Pb-Sb eutectic bearing-solder alloys with bismuth additions rapidly solidified from melt

In this work, various amounts of Bi element have been added to the eutectic Pb-Sb to form bearing- solder materials. The Pb-Sb eutectic has been produced by rapid solidification using melt spinning technique with various amounts of Bi have been added to it, in the ratio 1, 2 , 3, 4, and 5 wt.%. Scanning electron microscopy (SEM), X- ray diffraction (XRD) analysis and differential scanning calorimetry (DSC) have been carried out. Microhardness measurements were also carried out using Vicker’s hardness technique. The results showed that, the ternary alloys up to 4 wt.% Bi have properties superior to binary eutectic material. Bismuth up to 4wt. % increases the Young’s modulus, Vicker’s hardness and decreases the electrical resistivity, internal friction and melting point. The ternary Pb-13.1Sb-4Bi solder alloy has a lower melting point about 237.87 ?C. Also, the results show that formation of Bi phase developed the mechanical properties and Vicker’s hardness due to addition of Bi element. The addition of Bi refines the crystal size of Sn in case of melt spun alloys as seen in scanning electron micrographs and X-ray diffraction
