Dance Movement Therapy: A Promising Lifestyle Intervention in the Management of Chronic Obstructive Pulmonary Disease
Authors: Khan Iqbal Akhtar 
Published: August 2020

Chronic Obstructive Pulmonary Disease (COPD), a progressive multi-component malady with high morbidity and mortality, is an important public health challenge, throughout the world. Despite remarkable progress in its diagnostic and therapeutic modalities, significant number of patients, especially the elderly, continue to suffer from distressing dyspnoea and harrowing extra-pulmonary manifestations limiting their daily activities, with resultant exercise intolerance. Dance Movement Therapy (DMT), a pleasurable and feasible exercise, has been found to be equally effective at improving a range of health outcomes comparable with other forms of physical activity. Moreover, it has the potential to be a versatile activity with aesthetic expression, attractive to both genders irrespective of age, tempting to those with disabilities, and a fruitful tool in developing self-confidence. As viewed by European Association of Dance Movement Therapy �?DMT bridges the gap between the advantages of dance and the difficulties in performing physical activity and offers a combination of expressive movement and creativity…�? During the current stressful situation, caused by COVID-19 pandemic, the COPD patients, notably those over 70 years, are particularly vulnerable to intensification of symptoms and some of them may experience serious disorders of mental illness. Home isolation, social distancing,limiting outdoor activities and prohibiting participation in group exercises, though being appropriate prophylactic measures, are likely to add to already existing physical inactivity and heighten stress and depression, with deleterious effects on overall well-being. Solo dancing, while restricted to home, is a highly accessible, doable, sustainable and well rewarding alternative.
Nuclear level density with proton resonance using Gaussian orthogonal ensemble theory
Authors: Kadhim R. J. 
Published: August 2020

The Gaussian orthogonal ensemble (GOE) version of the random matrix theory (RMT) has been used to study the level density following up the proton interaction with 44Ca, 48Ti and 56Fe.
A promising analysis method has been implemented based on the available data of the resonance spacing, where widths are associated with Porter Thomas distribution. The calculated level density for the compound nuclei 45Sc,49Vand 57Co shows a parity and spin dependence, where for Sc a discrepancy in level density distinguished from this analysis probably due to the spin misassignment .The present results show an acceptable agreement with the combinatorial method of level density.

Authors: Ahmed Rasha S. 
Published: August 2020

The nuclear level density parameter in non Equi-Spacing Model (NON-ESM), Equi-Spacing Model (ESM) and the Backshifted Energy Dependent Fermi Gas model (BSEDFG) was determined for 106 nuclei; the results are tabulated and compared with the experimental works. It was found that there are no recognizable differences between our results and the experimental -values. The calculated level density parameters have been used in computing the state density as a function of the excitation energies for 58Fe and 246Cm nuclei. The results are in a good agreement with the experimental results from earlier published work.

Published: August 2020

DEMs, thus, simply regular grids of elevation measurements over the land surface.The aim of the present work is to produce high resolution DEM for certain investigated region (i.e. Baghdad University Campus\ college of science). The easting and northing of 90 locations, including the ground-base and buildings of the studied area, have been obtained by field survey using global positioning system (GPS). The image of the investigated area has been extracted from Quick-Bird satellite sensor (with spatial resolution of 0.6 m). It has been geo-referenced and rectified using 1st order polynomial transformation. many interpolation methods have been used to estimate the elevation such as ordinary Kriging, inverse distance weighted (IDW) and natural neighbor methods. The mosaic algorithm has then been applied between the base and building layers of studied area in order to perform the final DEM. The accuracy assessments of the interpolation methods have been calculated using the root-mean-square-error (RMSE) criterion. Finally, the estimated DEMs have been used to constructing 3-D views of the original image.

Authors: Jasim Mahdi Hadi 
Published: August 2020

The Neutron Fermi Age, t, and the neutron slowing down density, q (r, t) , have been measured for some materials such as Graphite and Iron by using gamma spectrometry system UCS-30 with NaI (Tl) detector. This technique was applied for Graphite and Iron materials by using Indium foils covered by Cadmium and the measurements done at the Indium resonance of 1.46 eV. These materials are exposed to a plane 241Am/Be neutron source with recent activity 38 mCi. The measurements of the Fermi Age were found to be t = 297 ± 21 cm2 for Graphite, t = 400 ± 28 cm2 for Iron. Neutron slowing down density was also calculated depending on the recent experimental t value and distance.

Authors: Flaiyh Ghaith N. 
Published: August 2020

The nucleon momentum distributions (NMD) for the ground state and elastic electron scattering form factors have been calculated in the framework of the coherent fluctuation model and expressed in terms of the weight function (fluctuation function). The weight function has been related to the nucleon density distributions of nuclei and determined from theory and experiment. The nucleon density distributions (NDD) is derived from a simple method based on the use of the single particle wave functions of the harmonic oscillator potential and the occupation numbers of the states. The feature of long-tail behavior at high momentum region of the NMD has been obtained using both the theoretical and experimental weight functions. The observed electron scattering form factors for 48Ti and 54Fe nuclei are in reasonable agreement with the present calculations throughout all values of momentum transfer q.

Authors: Jassim Amal K. 
Published: August 2020

Samples of Bi1.6Pb0.4Sr2Ca2Cu3O10+δ superconductor were prepared by solid-state reaction method to study the effects of gold nanoparticles addition to the superconducting system, Nano-Au was introduced by small weight percentages (0.25, 0.50, 0.75, 1.0, and 1.25 weight %). Phase identification and microstructuralcharacterization of the samples were investigated using XRD and SEM. Moreover, DC electrical resistivity as a function of the temperature, critical current density Jc, AC magnetic susceptibility, and DC magnetization measurements were carried to evaluate the relative performance of samples. x-ray diffraction analysis showed that both (Bi,Pb)-2223 and Bi-2212 phases coexist in the samples having an orthorhombic crystal structure. Both the onset critical temperatures Tc (onset) and zero electrical resistivity critical temperatures Tc (R=0) of the samples were determined from the DC electrical resistivity measurements. An improvement of the superconducting transition temperature of 6.36 % was obtained with increasing Au nanoparticles to x = 1.25 wt.%, while the critical current density is improved by 220 %. AC magnetic susceptibility measurement showed that the diamagnetic fraction and intergranular coupling of the x = 1.25 wt.% sample are greater than those of the others. The variation of magnetization with temperature (M-T curve) of the samples was measured by cooling the sample in zero fields (ZFC) and an applied field of 10 Oe (FC). The results of AC magnetic susceptibility and DC magnetization measurements were in good agreement with DC electrical resistivity measurement.

Authors: Nasir Eman M. 
Published: August 2020

ZnO thin films have been prepared by pulse laser deposition technique at room temperatures (RT). These films were deposited on GaAs substrate to form the ZnO/GaAs heterojunction solar cell. The effect of annealing temperatures at ( RT,100, 200)K on structural and optical properties of ZnO thin films has been investigated. The X-ray diffraction analysis indicated that all films have hexagonal polycrystalline structure. AFM shows that the grains uniformly distributed with homogeneous structure. The optical absorption spectra showed that all films have direct energy gap. The band gap energy of these films decreased with increasing annealing temperatures. From the electrical properties, the carriers have n-type conductivity. From C-V measurement of ZnO/GaAs heterojunciton solar cell at frequency 100, 200 KHz, It is found that built–in potential (Vbi) increases with increase frequency. Also, from I-V characteristic it is observed that the ideality factor is 2.7. Short-circuit current (Isc) is 4.0mA/cm2, open circuit voltage (Voc) is 0.5V, fill factor ( F.F) is 0.7 and the efficiency is about 6.0 %.
Optimization Procedures using Effect of Etalon Finesse and Driving Term on Optical Bistability
Authors: Khidhir Ali Hassan 
Published: August 2020

In this work, analytical study for simulating a Fabry-Perot bistable etalon (F-P cavity) filled with a dispersive optimized nonlinear optical material (Kerr type) such as semiconductors Indium Antimonide (InSb). Because of a trade off between the etalon finesse values and driving terms, an optimization procedures have been done on the InSb etalon/CO laser parameters, using critical switching irradiance (Ic) via simulation systems of optimization procedures of optical cavity. in order to achieve the minimum switching power and faster switching time, the optimization parameters of the finesse values and driving terms on optical bistability and switching dynamics must be studied.
In addition, for different values of a cavity finesse (for example, F = 25 and 2.37) the switching intensity takes low values with a high finesse etalon compared to a high switching intensity with a low finesse etalon. So, the minimum switching power for a low finesse etalon is ⁓0.785mW, and is about 0.0785mW for a high finesse etalon. The driving term peak of a high finesse etalon becomes higher and the slowing down region becomes less, leading to a fast switching as compared with a slow switching in a low finesse etalon. So that, the minimum switching time was about 300ns for a low finesse etalon, and about 150ns for a high finesse etalon.

Published: August 2020

Introduction: Lumbar degenerative spondylolisthesis is an acquired slippage of a vertebra due to degenerative arthritis of the facet joints without any defect in the vertebral ring. Degenerative spondylolisthesis is commonly treated with posterior decompression and posterolateral fusion. This study aims to evaluate the clinical outcome of posterior decompression and instrumented posterolateral fusion surgery by analysing patient reported outcome measures.
Materials and Methods: A retrospective study in which patients who had posterior decompression and instrumented posterolateral fusion for lumbar degenerative spondylolisthesis between September 2017 and August 2019 at Nepal Mediciti Hospital were included in the study. Other types of spondylolisthesis managed with similar technique and patients who had follow up period of less than three months were excluded. Functional outcome was assessed by comparing pre and post-operative patient reported outcome measures: VAS leg pain, VAS back pain and Oswestry Disability Index (ODI). The paired t-test was used for statistical analysis.
Results: Of the 16 patients, 81.25% were female. Mean age and mean follow up period were 58.81± 10.47 years and 13.56±7.15 months respectively. Seventy five percent had grade I spondylolisthesis. Most common level of spondylolisthesis was L4/5 (62.5%). Fourteen patients reported improvement in their symptoms after surgery. The changes in functional outcome scores between baseline and at follow up evaluation were as follows: 32.70 ± 17.44 points for ODI, 3 ±1.89 for VAS leg pain, and 5.37 ± 2.36 for VAS back pain (P<0.001). Superficial wound infection was the most common complication observed in 18.3%.
Conclusion: In our case series, 87.5% had improvement in their symptoms after surgery. The change in mean score of patients’ reported outcome measures before and after surgery was statistically significant. We recommend a prospective comparative study between decompression alone and the fusion technique for the evaluation of long term functional outcome.

Published: August 2020

The advent of Industrial Revolutions that swept the region has not spared the Malaysian business landscape. This has compelled industries to produce highly skilled workforce (Yizit and Yezim Denis, 2018) to promote knowledge-based skills in various sectors in Malaysia. Anticipating this change, the Malaysian Government initiated Technical Vocational Education and Training (TVET) program to address the issue during the early 90’s. However, the current highly pedagogical supply driven TVET system has not addressed the need to effectively upskill and reskill workforce talents to achieve maximum productivity. Hence, this study, which is grounded on empowerment theory, aims to develop mechanisms to skew the path towards industry-driven TVET by adopting heutagogical approaches that promotes lifelong and independent adult learning (Blaschke, 2012). The study will be executed using sequential exploratory design (mixed method) beginning with qualitative followed by a quantitative study by collecting samples via stratified random and proportional sampling technique whereby a framework will be developed to enable Government policymakers an impetus to formulate relevant strategies that forges the collaboration between the industry and academia.
