This study deals with the role of job satisfaction in developing administrative performance. The analysis was applied at Tikrit University. The study aimed to determine the role of job satisfaction in developing administrative creativity among employees. A sample of 77 heads of scientific departments in the university was randomly surveyed. A 32-question survey was assigned to the sample individuals. The response rate was 90%. SPSS software was used to statistically analyze surveyed data. The results showed the validity of the hypotheses that job satisfaction causes a positive influence on the development of creativity of employees. The statistical analyses of data obtained proved positive morale among individuals’ creativity in work at the university. The means and standard deviations revealed the surveyed respondents’ tendency to accept the job satisfaction dimensions such as career growth, motivation, work environment, and functional tasks. The means and standard deviations revealed the surveyed respondents’ tendency to accept the administrative creativity dimensions such as problem solving, changeability, accept risks, and encourage creativity. Based on the statistical outcomes, the present study recommended rewarding the employees based on their achievements. Also, the university administration should consider and solve the university employees’ problems.

Ashok Dalal,Ujjwal Sonika,Manish Kumar,Roshan George,Ajay Kumar,Siddharth Srivastava,Sanjeev Sachdeva,Barjesh Chander Sharma 대한소화기내시경학회 2021 Clinical Endoscopy Vol.54 No.4

Background/Aims: The severe acute respiratory syndrome coronavirus 2 pandemic has affected the gastrointestinal (GI) endoscopyunits globally owing to the risk of transmission. We present our data on the use of rapid antigen test (RAT) as a screening tool priorto endoscopy to prevent the transmission of coronavirus disease (COVID-19). Methods: This study was a retrospective analysis of patients who underwent any GI endoscopic procedure from July 2020 to October2020 at a tertiary referral center in New Delhi, India. All patients underwent screening for COVID-19 using RAT, and endoscopywas performed only when the RAT was negative. The data are presented as numbers and percentages. Results: A total of 3,002 endoscopic procedures were performed during the study period. Only one endoscopic procedure wasperformed in a COVID-19 positive patient. A total of 53 healthcare workers were involved in conducting these procedures. Only2 healthcare workers (3.8%) were diagnosed COVID-19 positive, presumably due to community-acquired infection, during thisperiod. Conclusions: The COVID-19 RAT is easily usable as a simple screening tool prior to GI endoscopy during the COVID-19 pandemic.

Results of Single-Staged Posterior Decompression and Circumferential Fusion Using a Transpedicular Approach to Correct a Kyphotic Deformity due to Thoracolumbar Spinal Tuberculosis

Study Design: This is a prospective study. Purpose: The aim of this study was to investigate the results of single-staged posterior decompression and circumferential fusion using a transpedicular approach to correct a kyphotic deformity due to thoracolumbar spinal tuberculosis. Overview of Literature: Surgical management is frequently an imperative choice to achieve spinal decompression and deformity correction due to tuberculosis to relieve pain, improve neurology, and reconstruct the spine stability. Since the time anterior radical debridement and noninstrumented fusion was described, it has become apparent that even anterior debridement and bone grafting was often unsatisfactory in correcting or preventing the progression of kyphosis deformity. With the advent of modern segmental spinal instrumentation systems, isolated posterior instrumentation; combined anterior and posterior fusion; and single-staged posterior decompression and circumferential fusion have been described by many authors for correcting angular deformity and stabilizing the spine; however, there is a lack of consensus regarding the most effective means of correcting the deformity due to thoracolumbar spinal tuberculosis. Methods: This is a prospective study of 20 patients with thoracolumbar spinal tuberculosis who underwent surgery at our institute. Results: Twenty patients who were started on antituberculosis treatment underwent surgery using a single-staged posterior approach involving fixation, decompression, and kyphosis correction. Preoperatively, all patients had varying degrees of neurological deficit and a 27.45° average kyphotic angle, which improved. At the 1-year follow-up, correction was maintained at 6.9°, and 55% of patients showed neurological improvement. None of the patients experienced neurological deterioration. Two patients with lumbar spine tuberculosis underwent revision surgery because of nonunion. Conclusions: The procedure of posterior decompression, fixation, and circumferential fusion using a transpedicular approach performed for thoracolumbar spinal tuberculosis is effective, safe, and excellent in correcting and maintaining kyphosis.

MAHDI, Dalal Salih,AL-NAIMI, Adnan Tayeh Korea Distribution Science Association 2021 The Journal of Asian Finance, Economics and Busine Vol.8 No.3

In this paper, the relationship between the profitability level of an enterprise and the credit policy adopted by an enterprise was measured. A sample of industrial firms listed on the stock exchanges of Iraq, Jordan, and Kuwait was analyzed. Five industrial firms were randomly selected from each exchange with a condition of having at least 5 year-activity. The total sample size was 15 industrial firms. The study financial data was imported from the sample firms' websites. The financial data was for the financial year 2017. The Regression Analysis was adopted to measure the impact of trade credit on the profitability of an enterprise using the SPSS software. It was found that the receivable accounts have a proportional relationship with the turnover property rights rate. Similarly, the statistical results showed that the turnover property rights rate increased with an increase in the turnover receivable accounts rate and the percentage of investment in receivable accounts. The influence of trade credit on the enterprise profitability percentage in the Iraq stock exchange, Amman stock exchange, and Boursa Kuwait were 0.938, 0.200, and 0.089, respectively. The results showed that the three secondary assumptions were incorrect, while the zeroth assumption, i.e., trade credit has no influence on profitability, was correct.

Graphene FETs based on high resolution nanoribbons for HF low power applications

David Mele,Sarah Mehdhbi,Dalal Fadil,Wei Wei,Abdelkarim Ouerghi,Sylvie Lepilliet,Henri Happy,Emiliano Pallecchi 대한금속·재료학회 2018 ELECTRONIC MATERIALS LETTERS Vol.14 No.2

In this paper we present high frequency field effect transistors based on graphene nanoribbons arrays (GNRFETs). Thenanoribbons serve as a channel for the transistors and are fabricated with a process based on e-beam lithography and dryetching of high mobility hydrogen intercalated epitaxial graphene. The widths of the nanoribbons vary from 50 to 20 nm,less than half those measured in previous reports for GNRFETs. Hall measurements reveal that the devices are p-doped, withmobility on the order of 2300 cm2/Vs. From DC characteristics, we find that the maximum ratio IMAX/IMIN is 5 obtained at50 nm ribbons width. The IV characteristics of the GNRFETs are slightly non-linear at high bias without a full saturation. Therefore, despite the aggressive scaling of the graphene nanoribbon width, a bandgap is still not observed in our measurements. The high frequency performances of our GNRFETs are already significant at low bias. At 300 mV drain sourcevoltage, the highest intrinsic (extrinsic) cut-off frequency ftreaches 82 (18) GHz and the extrinsic maximum oscillationfrequency fmaxis 20 GHz, which is promising for low power applications.

Experimental Observation of Hydrogen in a Mixed State of Order-disorder and Displacive Behavior in Squaric Acid

김세훈,이철의,N. S. Dalal,한덕영 한국물리학회 2010 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.57 No.5

H2C4O4 (Squaric acid, henceforth abbreviated by SQA) is one of the most studied hydrogenbonded anti-ferroelectrics in the KH2PO4 (KDP) family. Here, we report the static hydrogen lineshape which shows a mixed state behavior of order-disorder and a displacive feature in the antiferroelctric (AFE)/paraelectric (PE) phase transition of SQA. We obtained the dipolar splitting data from the nonlinear fitting curve of the static hydrogen lineshape. The calculated proton-proton distance showed an increase at temperatures above the transition temperature Tc. As temperature increases through Tc, the inter-atomic distance shows a peculiar S-shape variation. This S-shape variation around Tc is also observed in other NMR reports for SQA, where the chemical shift variation is used to characterize the deformation of the C4O4 squarate group. Here, we used the dipolar interaction, instead of the chemical shift information, to detect the geometrical change of the hydrogen. Below the transition temperature Tc, the proton interactions showed long-range order whereas it showed short range order at temperatures above Tc. The peculiar S-shape variation from the hydrogen lineshape analysis can be understood as another piece of experimental evidence for a mixed state for the phase transition in SQA.

High-resolution 31P nuclear magnetic resonance studyof phase transitions in TlH2PO4

CheolEuiLee,N.S.Dalal,R.Fu 한국물리학회 2003 Current Applied Physics Vol.3 No.5

High-resolution 31P nuclear magnetic resonance (NMR) techniques were employed to study a KH2PO4-type ferroelectric system, TlH2PO4. A marked temperature dependence of the isotropic chemical shift below the ferroelastic phase transition temperature is indicative of an electronic instability. The NMR linewidth showed a discontinuity at the ferroelastic phase transition, and the anisotropy was measured to increase rapidly below the antiferroelectric phase transition. Thus, the changes in the microscopic environments associated with the phase transitions were sensitively reflected in a characteristic manner. 2003 Elsevier B.V. All rights reserved.
