Investigation of the effect of the value added, earning quality and leverage ratio on bankruptcy in organizations accepted in Tehran’s stock market

The recent bankruptcy of large organizations, internationally, and the frequency of stocks in the stock and share market in Iran show the necessity of some tools in order to evaluate the financial ability of organizations. One of the tools for evaluating the financial ability of organizations is using the key criteria as an independent variable and analyzing some earning figures to study the bankruptcy of organizations. This article is going to investigate the effect of economic value added, earning quality and leverage ratio on the bankruptcy of the amount of credit indexes in Tehran’s stock and shares market. The results of the research will show that in accepting organizations in stock and share market of Tehran, the economic criteria of value added and the leverage ratios are better indexes to predict the bankruptcy and are able to show the possibility of bankruptcy to the shareholders. One of the other results of this research is to mention that the economic value added is an index which is capable to be exchanged with other indicators of performance evaluation for managers and owners in order to achieve the goal of maximizing the wealth of shareholders

Adult onset still disease associated with endogenous lipoid pneumonia

Cholesterol pneumonia or endogenous lipid pneumonia (ELP) is a rare disease that can occur in the context of a systemic diseaseor following a bronchial obstruction. It is characterized by a wide range of diverse symptoms and various disease course. Thepresent report introduces a young woman diagnosed with adult onset still disease three years ago, who has been referred withmacrophage activation syndrome (MAS). She underwent biopsy due to dyspnea and a crazy paving pattern in HRCT of the lungs,leading to the diagnosis of lipoid pneumonia based on the interstitial lymphocytic inflammation and cholesterol granulomas. Sofar, there has been no report indicating MAS associated with cholesterol pneumonia. This is the second case reporting ELP inthe adult onset still disease

Long-term effect of zinc oxide nanoparticles on population growth, reproductive characteristics and zinc accumulation of marine rotifer, Brachionus plicatilis

In the present study, the effects of ZnO nanoparticles (NPs) on marine rotifer, Brachionus plicatilis, was investigated in three separate experiments. Firstly, the sensitivity and reproductive characteristics of B. plicatilis were studied at concentrations of 0, 0.1, 0.5, 1, 3, 5 and 10 mg L-1 of ZnO-NPs for 10 days. Based on the results, the total number of rotifers (TNR) significantly decreased at 5 and 10 mg L-1 of ZnO-NPs. In addition, the specific growth rate (SGR) of animals was negative at two of the concentrations of ZnO-NPs. In the second experiment, the TNR at 4 concentrations of ZnO-NPs (0, 10, 13, 17, and 19 mg L-1) during 72 h were tested and the 24-72 h LC50 of ZnO-NPs was calculated. After three days, the entire population of rotifers was generally lost at 19 mg L-1 of ZnO NPs. The LC50 of ZnO-NPs in animals at 24, 48, and 72 h intervals was registered as 18.2±1.34, 12.43±0.08, and 9.63±0.26 mg L-1, respectively. Finally, the zinc accumulation in rotifers was measured at different concentrations (0, 0.1, 0.5, and 1.3 mg L-1) of ZnO-NPs and maximum zinc (123 μg g-1 of rotifer DW) uptake by rotifers was observed in treatment 3 mg L-1 of ZnO-NPs. In sum, it can be concluded that the B. plicatilis can be used as a biological model for studying marine water contaminants with nanoparticles, especially ZnO-NPs

TM-vector: A Novel Forecasting Approach for Market stock movement with a Rich Representation of Twitter and Market data

Stock market forecasting has been a challenging part for many analysts and researchers. Trend analysis, statistical techniques, and movement indicators have traditionally been used to predict stock price movements, but text extraction has emerged as a promising method in recent years. The use of neural networks, especially recurrent neural networks, is abundant in the literature. In most studies, the impact of different users was considered equal or ignored, whereas users can have other effects. In the current study, we will introduce TM-vector and then use this vector to train an IndRNN and ultimately model the market users' behaviour. In the proposed model, TM-vector is simultaneously trained with both the extracted Twitter features and market information. Various factors have been used for the effectiveness of the proposed forecasting approach, including the characteristics of each individual user, their impact on each other, and their impact on the market, to predict market direction more accurately. Dow Jones 30 index has been used in current work. The accuracy obtained for predicting daily stock changes of Apple is based on various models, closed to over 95\% and for the other stocks is significant. Our results indicate the effectiveness of TM-vector in predicting stock market direction.Comment: 24 pag

Production and Warranty Optimal Period in Deteriorating Production Systems by Considering Inspection of both Manufacturing Equipment and Products Simultaneously

Traditionally high share of production-distribution costs to inventory and supply policy dedicated. The production model of politics is important for a system of distribution, taking into account the actual conditions of production and optimal production parameters influenced. One of these conditions is that the production equipment during production turned out of control and produce defective products. It is possible to change the mode in real terms, and then significantly increase the amount of defective products. Despite these conditions, one of the parameters affecting the demand for products and sales, and consequently the amount of corporate profits is the product warranty. The after-sales service product parameter influencing the willingness of consumers to buy the product. In this work, it consider the potential failure of production equipment, as well as the product warranty, mathematical models of inventory control policy, based on actual production conditions for the production units. This model is aimed at achieving the optimal length of time in each period and for optimum product warranty with respect to maximizing profits per unit of time. In other words, the goal is create an optimal balance between product sales revenue and costs incurred during the period of warranty for the product. In fact, in this article will discuss this model and its resolution

Experimental investigation of the effect of Vitagnus plant extract on enhanced oil recovery process using interfacial tension (IFT) reduction and wettability alteration mechanisms

© 2020, The Author(s). Surfactant flooding is a chemical enhanced oil recovery (cEOR) process wherein anionic, cationic, non-ionic, and amphoteric surfactants are injected into oil reservoirs to produce more hydrocarbon. These chemical and industrial agents might cause some economic and environmental challenges. Recently, injection of natural surfactants, as new environmentally friendly EOR agents, for improving oil recovery has been proposed by researchers. In this study, the extract of Vitagnus, a natural surfactant, was used to minimize the interfacial tension (IFT) and alter the rock wettability towards the strong water-wet system, thereby improving the oil recovery from the carbonate rock The conductivity, pH, and turbidity measurements were undertaken to identify the critical micelle concentration (CMC) of the surfactant solutions prepared by mixing 500, 1000, 2000, 3000, 4000, 5000, 6000, and 7000 ppm of the Vitagnus extract and distilled water. The obtained experimental results reveal that the optimum CMC value of the used surfactant was 3000 ppm. At this CMC value, the IFT reduced from 29.5 to 5.28 mN/m, and the contact angle of the oil droplet on the surface of the carbonate rock decreased from 114° to 29°. Accordingly, during the tertiary process, oil recovery was improved from 44% to 54.6% OOIP (original oil in place) by injecting 2.25 PVs of the VIT3000 surfactant containing 3000 ppm of the plant extract
