Background: The changes before and after fluid resuscitation in patients with septic shock and their relationship with prognosis have rarely been reported. Objectives: We aimed to observe the correlation between pulmonary vascular permeability index (PVPI), shock index (SI), and severity of septic shock. Methods: This case-control study retrospectively analyzed the clinical data of 154 patients with septic shock treated at our hospital (Weifang, China) from October 2016 to October 2018. They were divided into a survival group or a death group according to the 28-day prognosis. Univariate analysis was performed for vital signs, the acute physiology and chronic health evaluation II (APACHE-II) score, the sequential organ failure assessment (SOFA) score at admission, SI at admission (SI1), SI at 3 h after fluid resuscitation (SI2), PVPI at admission (PVPI1), PVPI at 3 h after fluid resuscitation (PVPI2), and lactate clearance rate (LCR). The correlations of PVPI and SI with the APACHE-II score, SOFA score, and LCR were analyzed by plotting the receiver operating characteristic curves. Results: Among the 154 cases, 70 survived after 28 days and 84 died. We observed that SI1, SI2, PVPI1, PVPI2, APACHE-II score, and SOFA score were significantly lower in the survival group than in the death group, while LCR was significantly higher (P < 0. 05). Also, SI1, SI2, PVPI1, and PVPI2 were positively correlated with APSCHE-II and SOFA scores of patients with septic shock, but negatively correlated with LCR (P < 0. 05). Moreover, SI2 predicted the prognosis of patients with septic shock significantly better than SI1, PVPI1, and PVPI2 did. When SI2 was 1. 22, the Youden index was 0. 822, the sensitivity was 91. 23%, the specificity was 89. 47%, the positive predictive value was 0. 912, and the negative predictive value was 0. 924. The positive and negative likelihood ratios were 0. 897 and 0. 375, respectively. Conclusions: Based on the study, SI after fluid resuscitation was more valuable for evaluating the prognosis of patients with septic shock than SI at admission, as well as PVPI values at admission and after fluid resuscitation.

Permeability estimation using core data and petrophysical logs is a conventional approach which bears high uncertainty especially in carbonate reservoir characterization. In essence, the problem consists not only due to coring expenses rate, but also ambiguity in finding proper explicit log correlation to core data. Moreover, utilizing the correlated formula in wells without core data can pose errors. In this research the permeability was estimated from conventional petrophysical logs and it was calibrated with permeability obtained from core lab experiments.Applied intelligent systems are the matter of this research for permeability values estimation. To construct permeability estimation model, three techniques have been applied including conventional ANN, the Gonzalez, and Hambalek fuzzy logic techniques. These methods were applied in two wells drilled in Surmeh reservoir in Balal field to establish ANN and to derive a relation between core and well. The models were applied in control well in order to check the reliability and capability of models to estimate representative permeability value. The result showed however three foresaid techniques for permeability estimation were successful the secondary porosity distributed the correlation due to its reduction effect on permeability so that they were not interconnected. Therefore this effect was omitted using secondary porosity index in which the permeability estimation were improved and were estimated close to core value.

1. Introduction:In the design process of geo-environmental engineering projects, the use of soil mechanics experiments and specially permeability results has a noticeable impact [1]. In other words, one of the main parameters in the design process of waste disposal sites and earth dam design is the soil permeability. However, in geotechnical and geo-environmental projects there is a lack of attention to the influence of clay mineral type and variation of properties of soil pore fluid on the error associated with soil mechanics experiments. For these reasons, in this research the influence of clay mineral type and properties of soil pore fluid on the errors of consolidation and permeability coefficients are investigated. …

Salman Farsi is located in 180 kilometers of the southeast of Shiraz on the Ghareh-Agai River with the arch-gravity concrete dam of 125m height from the foundation. The grout curtain is situated entirely within the karstic limestone environment in the Asmari formation. To evaluate the quality of the curtain after grouting operation, some boreholes were drilled and water pressure tests were performed on them. In this research, according to the results of water pressure tests on the controlled boreholes, the secondary permeability index was calculated and through the classification of the rock masses, their quality were determined after the grouting operation. Results indicate that although the right bank of grout curtain has better quality than the left bank, however the quality of the grout curtain has been in the range of good to excellent.

Background and objectives: Carpal Tunnel Syndrome (CTS) is the most common mononeuropathy encountered in clinical practice. Conventional electro diagnosis studies have been useful in the diagnosis of this condition. The Terminal Latency Index (TLI) is a derived neurophysiological value that adjusts the Distal motor Latency (DL) for the terminal distance and motor nerve Conduction Velocity (CV).Several studies have suggested utility of the median TLI for diagnosis of CTS.The goal of this study is to evaluate prospectively the sensitivity of the median TLI in the diagnosis of CTS and compare it with other electrodiagnosis techniques.Material and Methods: This study was done on 111 patients as CTS group & 62 healthy subject as control group. In all groups five selected tests of electrodiagnosis were done and all of them were compared with TLI sensitivity.Results: The mean TLI was 0.3±0.05 in the CTS group and 0.42±0.03 in the control group. The sensitivity of TLI was 73% The TLI wasn't statistically better than the other tests, but in three cases from the CTS group, the TLI was the only abnormal test.The 7 and 14 cm method had meaningful sensitivity in contrary to other tests.Conclusion: The sensitivity of TLI has no meaningful difference with other routine electro diagnostic tests in diagnosis of CTS.The median TLI is a useful but not more sensitive electrodiagnostic test for CTS.

Introduction: Three methods of OCRA Index, Strain Index (SI), and ACGIH HAL have been proposed for the assessment of risk factors of upper limb musculoskeletal disorders. Investigating the correlation and consistency of these three methods are of prominence importance in the workplaces. Thus, this study aimed to determine the correlations of the results of the above mentioned methods. Materials and Methods: In this cross-sectional study, a total of 150 tasks were studied in four industries. For each task, a video taping of a full working cycle was prepared and evaluated according to the instructions of each method. The level of risk exposure to musculoskeletal disorders was analyzed with correlation and Kappa agreement coefficient tests using SPSS (version 16) and R software packages.Results: The correlation between the results of risk assessments of OCRA and SI methods for right and left hands were acceptable and equal to 0.751 and 0.726, respectively (p<0.001). Meanwhile, the coefficients of agreement between OCRA and HAL methods for left and right hands were 0.526 and 0.595, respectively.Conclusion: These findings partly confirmed the agreement between the methods of risk assessment. The origin of this partial agreement can be the number and type of variables and their impacts on the final score of the methods.

The main objective of water spreading projects is recharging aquifers. In this study, changes of soil surface permeability in Yazd water spreading projects, including Sirizi in Bafgh, Herat and Miankouh in Mehriz were investigated. Using a double ring, 12 Permeability tests (in first and fourth strips and three tests for each strip) were performed. Using measured data the performance of permeability equations such as Kostiakov, Kostiakov-Lewis, Horton, SCS, and Philip were compared in estimating cumulative infiltration and infiltration rate in the study areas. Results showed that average permeability for Bafgh, Herat and Mehriz water spreading projects were about 1. 06, 1. 52 and 2. 94 cmhr-1, respectively. The best equation for estimating cumulative infiltration in Bafgh was the Horton equation with RMSE and Nash Sutcliffe coefficients of 0. 097 and 0. 992, respectively, while in Herat and Mehriz the best equation was the Kostiakov-Lewis equation with Nash-Sutcliffe coefficient and RMSE of 0. 385, 0. 994, 0. 081 and 0. 991 respectively.
