Rhabdomyolysis due to hypothyroidism is uncommon, and there have been few case reports of repeated rhabdomyolysis in patients with hypothyroidism. We report a rare case of repeated rhabdomyolysis in a patient with hypothyroidism. The patient was a 65-year-old Japanese male who presented to an outside hospital with bilateral lower extremity weakness; he was diagnosed with hypothyroidism and successfully treated with levothyroxine. His symptoms and laboratory parameters improved with treatment such that he was safely discharged. However, the patient was non-compliant with his levothyroxine beginning at 10 weeks after his discharge and re-presented with bilateral lower extremity weakness and myalgias 18 weeks after stopping his thyroid supplementation. He was readmitted to our hospital and was again diagnosed with rhabdomyolysis secondary to Hashimoto’s thyroiditis. Serological thyroid function and muscle enzymes normalized after the second dose of levothyroxine. The patient has remained symptom-free without recurrent episodes of rhabdomyolysis at two-year follow-up.
The amounts of six heavy metals (Fe, Cd, Co, Cr, Ni, and Pb) were measured in all 15 sediment samples, which included three drains south of Manzala Lake (Egypt). The possible environmental risks of metals in the sediment of the three drains were investigated using soil indices and risk assessment. Results showed that heavy metal contamination was found at the studied sites along the three drains, and pollution levels varied depending on metals and sites. The mean concentration (mgkg-1) ranked in the order of Fe(3950.24) ˃ Cd(22.36) ˃ Cr(21.15) ˃ Co(19.01) ˃ Pb(14.16) ˃ Ni(10.40) for Faraskour drain, Fe (5067.80) ˃ Cd (30.29) ˃ Co (18.97) ˃ Cr (16.90) ˃ Ni(15.03) ˃ Pb(12.16) for Al-Etaiwy drain and Fe(12.56.12) ˃ Cd(19.60) ˃ Co(17.15) ˃ Ni(14.88) ˃ Cr(10.10) ˃ Pb(10.03) for Ramsis drain. The mean ranges of enrichment factor for Cd, Co, Pb, Ni and Cr were 167.46-3858.37, 6.11-51.78, 4.38-31.20, 1.07-11.84 and 0.61-7.43, respectively. The average degree of contamination revealed that the majority of the sites had reached very high levels of pollution, with the exception of site 1, which had reached a moderate level of contamination. The ecological risk of heavy metals can be ranked as follows: Cd>Co>Pb>Ni>Cr, and the PERI were 930.99, 1173.17 and 818.48 in the Faraskour, Al-Etaiwy and Ramsis drains, respectively. To decrease pollution, it was determined that more effective restrictions on Cd and Co were needed.
This study was designed to explore the floristic composition and ecological characteristics of vascular plants of the study area. Plant species were collected during field trips in three seasons viz., winter, summer and monsoon. The plants were classified into different life form and leaf size classes. The Pteridophytes consisted of 1 family and 1 species, gymnosperms had 2 families and 2 species and angiosperms were represented by 44 families and 121 species (6 families and 15 species of monocots and 38 families and 106 species of dicots). The Pteridophytes constituted less than 1% while gymnosperms were 1.62% and angiosperms were 98.37%. Among angiosperms, monocots were 12.39% and dicots 87.60% of the total collected species. The leaf shape classes showed that 99 (80.48%) species had simple leaves while 24 (19.51%) species possessed compound leaves. In spinyness 27 (21.95 %) species were spiny while 96 (78.04%) species were non-spiny. Biological spectrum of flora indicated that Therophyte were dominant (34.95%), followed by Nannophanerophyte (22.76%). Leaf spectra revealed that Microphyllous (28.45%), Mesophyllous (26.01%), Nanophyllous (24.39%) were the most prevalent leaf size.
Purpose: The purpose of this study was to determine whether leisure time physical activity (PA) affects metabolic syndrome (MetS) in Korean adults. Methods: The subjects were 1,728 adults over age 20 who visited a public health promotion center in Seoul, Korea. All subjects completed the International Physical Activity Questionnaire, and their MetS factors were measured and then defined by the National Cholesterol Education Program’s Adult Treatment Panel III criteria. The association between PA and MetS was assessed using multivariate logistic regression analysis. Results: The odds ratios (95% confidence interval) for having MetS and engaging in vigorous PA, moderate PA, and light PA (walking) compared with having MetS and not engaging in vigorous PA, moderate PA, and light PA (walking) were 0.482 (0.322–0.721, p < 0.001), 0.547 (0.370–0.810, p = 0.003), and 0.482 (0.318–0.731, p < 0.001) for once a week, respectively, and 0.763 (0.468–1.243, p = 0.277), 0.697 (0.419–1.160, p = 0.165), and 0.674 (0.403–1.128, p = 0.134) for twice a week, respectively. For thrice a week, these figures were 0.449 (0.248–0.815, p = 0.008), 0.568 (0.338–0.954, p = 0.033), and 0.451 (0.260–0.780, p = 0.004), respectively, and for 4 times a week, the relevant figures were 0.321 (0.123–0.835, p = 0.020), 0.737 (0.362–1.502, p = 0.401), and 0.411 (0.185–0.916, p = 0.030), respectively. The relevant figures for over 5 times a week were 0.216 (0.064–0.727, p = 0.013), 0.390 (0.166–0.915, p = 0.031), and 0.318 (0.181–0.558, p < 0.001), respectively. Conclusion: These findings indicate that vigorous PA, moderate PA, and walking (light PA) may prevent or reduce MetS in Korean adults.
The duct model used here is that Kahan and Eckart [1950]. The source of the electromagnetic field is taken to a vertical magnetic dipole in the upper surface layer, with an arbitrary time – varying moment , we can determine the transient behaviour of the electric field strength at any distance above the duct .The paper presents a method which allows the calculation of the atmospheric distortion of radar pulse , provided that the influence of the atmosphere is to transfer the transmitted signal through a duct .the polarization of the primary source whose moment varies arbitrarily in time, is chosen in such a way that it allows the exact determination of the electric field strength at some field point above the duct layer .From the physical point of view. Cahniard s idea is applicable as it is based on evaluating the field in a series of image sources of the primary source . The step – function solution of the problem can then be determined as an infinite integrals over finite integrals.Two cases would be distinguished on the basis of the distance between the receiving and transmitting ends and whether it is greater or lesser than the total reflection distance.

Due to their numerous advantages, gas turbine (GT) power plants have become an important technology for power generation. A parametric analysis for the different configurations of the gas-turbine plant with effects of isentropic compressor and turbine efficiency are presented in this paper. The optimum configuration for gas-turbine was proposed to select optimum performance of a gas-turbine power plant with effects the isentropic compressor and turbine efficiency. The computational model was developed utilizing the MATLAB software.The simulated results show that the reheat gas-turbine configuration (HGT) has higher power output, while the regenerative gas-turbine configuration (RGT) has higher thermal efficiency with effects the isentropic compressor and turbine efficiency. The maximum thermal efficiency about 52.4 % and the maximum power output about 268MW obtained with the isentropic turbine efficiency. The obtained result reveals that the isentropic compressor and turbine efficiency are strongly influenced o the performance of gas-turbine.
Grinding is an often important finishing process for many engineering components\nand for some components it is even a major production process. In this study, prediction model\nhave been developed to find the effect of grinding condition in term of depth of cut and type of\ngrinding coolant. Zinc Oxide (ZnO) nano-coolant was used as a coolant with water as a based\nliquid. The experiments conducted with grinding depth in the range of 5 to 21μm. Silicon\nCarbide wheel are used to grind the AISI P20 tool work piece. Artificial intelligence model has\nbeen developed using Artificial Neural Network(ANN). Result shows that the lower surface\nroughness and wheel wear obtain at the lowest cutting depth which is 5 μm. Besides that, grind\nusing ZnO nano-coolant gives best surface roughness and minimum wheel wears compared to\ngrind using normal soluble coolant. The surface roughness have been reduced approximately\n47.84% for single pass experiment and 126.1% for multi pass experiment. However, there is no\nwheel wheel wear obtain for grinding using ZnO nanocoolant. From the prediction of ANN, it\ncan predict the surface roughness closely with the experimental value.
The growth in the development of wireless sensor networks and their applications in many areas demand an efficient security system. But providing security in wireless sensors network is not upfront compared to the other wireless networks due to the resource constraints of the sensor nodes. The symmetric key cryptography is a suitable mechanism to provide security when considering the resource constraints of the sensor nodes. The effectiveness of the security mechanism depends purely on the underlying key management technique, especially, how efficiently the keys are distributed to the sensor nodes. Here, the authors propose a key pre-distribution algorithm which uses modulo operation. This deterministic approach encourages an outsized network with better connectivity and less communication overhead through minimal memory requirement using a small key pool.
