An experimental study of the absorption of CS$_{2}$ in the secondary amine diethanolamine(DEA) was performed in this work. The primary objectives were to investigate an analogy between N2O and CS$_{2}$ permitting estimation of the physical solubility and diffusivity of the sulfur gases in the reacting amino solutions. The solubilities of CS$_{2}$ in water at 25, 40 and 6$0^{\circ}C$ has been measured. The data show fair agreement with previous literature values. The solubility of CS$_{2}$ in 5-25 weight % polyethylene glycol has been measured in order to investigate a possible analogy between CS$_{2}$ and N$_{2}$O The diffusivities of CS$_{2}$ in water and the reaction rate between CS$_{2}$ and DEA has been measured at 25 and 4$0^{\circ}C$, using a wetted sphere apparatus operated at approximately 1/3 atmospheres pressure, which is a previously untried method.

We consider a history-dependent Parrondo game in which the winning probability of the present trial depends on the results of the last two trials in the past. When a fraction of an infinite number of players are allowed to choose between two fair Parrondo games at each turn, we compare the blind strategy such as a random sequence of choices with the short-range optimization strategy. In this paper, we show that the random sequence of choices yields a steady increase of average profit. However, if we choose the game that gives the higher expected profit at each turn, surprisingly we are not supposed to get a long-run positive profit for some parameter values.

In this study, the availability of Schmidt hammer has been investigated as a reliable method to determine the quality of concrete in irrigation networks. For this purpose, the 28-day compressive strength of concrete material used in the construction irrigation channel of Bafra lowland, which is one of the most fertile plains in Turkey was examined by means of concrete compression and as well as concrete Schmidt hammer in laboratory conditions. This study was carried out on cylindrical samples to represent the everyday concrete party ($150m^3$) produced by contractor firm as 3 replications. The statistical analysis of experimental data showed that the correlations between the values of 28-day compressive strength of Schmidt hammer and the rebound number was found to be 0.98. Differences of the compressive strength between compression testing and Schmidt hammer were statistically significant at P<0.01. In this context, it was found that the reliability of compressive strength of the concrete compression test are excellent, also the reliability of compressive strength of Schmidt hammer are fair in assessing the quality of concrete irrigation channels.

Temporal and spatial prediction of water quality provides the necessary information to a profect planning, design, and model optimization for water quality mangement in a river system. In thes study, the QUAL II model is applied to the Keum River system from the downstream of Dae-Chong dam to the Great Pak-Je bridge. The advection-dispersion model of water quality based on the material balance and the numerical solution method of the model are presented. The enhancement of the model application is empha sized by comparing the observed and the simulated values of BOD, DO, and water temperature. Through these processes, the water quality states of the Keum River system are evaluated and the deoxignation rate, the reaeration rate, and Fair value are estimated. Also, the maintance of the target DO level with the control of the discharge from Dae-Chong dam is discussed.

Purpose: To evaluate the usefulness of wash-in color map in detecting early enhancement of prostate focal lesion compared to whole dynamic contrast-enhanced MRI (DEC MRI) images. Materials and Methods: This study engaged 50 prostate cancer patients who underwent multiparametric MRI and radical prostatectomy as subjects. An expert [R1] and a trainee [R2] independently evaluated early enhancement and recorded the time needed to review 1) a wash-in color map and 2) whole DCE MRI images. Results: The review of whole DCE images by R1 showed fair agreement with color map by R1, whole images by R2, and color map by R2 (weighted kappa values = 0.59, 0.44, and 0.58, respectively). Both readers took a significantly shorter time to review the color maps as compared to whole images (P < 0.001). Conclusion: A trainee could achieve better agreement with an expert when using wash-in color maps than when using whole DCE MRI images. Also, color maps took a significantly shorter evaluation time than whole images.

This research aims to expose the Islamic perspective on the concept of justice on the Mudarabah contract's profit-sharing ratio. In certain verses in Al-Qur'an, Islamic values in Muamalah, the rules dictated by the Qur'an and its practices, and explanations rendered (more commonly known as Sunnah) by the Prophet Muhammad (pbuh) and Sahabah (the companions of the Prophet Muhammad), and Fiqh Axiom (rules) in Muamalah (Islamic jurisprudence), are used as the instruments of sharia to achieve the study objective. Islamic monetary establishments in Indonesia are still not in full consistency with the Shariah principles, significantly as far as satisfying equity and justice by Islamic banks in mudarabah contract (with clients). The ignominy is the nisbah (ratio) between the capital proprietor and the capital director. There are models or propositions to decide the benefit (profit)-sharing proportion. Nevertheless, none of them explains or specifies the possibility of equity/justice in the profit-sharing ratio. This research utilizes an explorative and subjective methodology that contributes to the philosophical premise of deciding the profit-sharing fairness. The elements of a just ratio for the Mudharabah contract are mutual willingness, the existence of negotiation, and the level of advantages and risks of the labor.

As Islam supports fair trade, the Murabaha is the most popular and most common mode of Islamic financing. It is a contract of sale between the bank and its client for the sale of goods at a price plus an agreed profit margin for the bank. The contract involves the purchase of goods by the bank which then sells them to the client at an agreed mark-up. While their characteristics and values are unique, they are also subject to conventional measurement of efficacies. This study investigates how the primary health predictors of conventional banks under the Basel III regime could provide a positive means to assess the Murabaha funding and subsequently secure long-term profitability. This study constructed a path analysis (from 120 databases) to assess whether Islamic banks' leverage and capital adequacy may alter the Murabaha funding and increase stock equity directly and indirectly. The research findings are mixed where leverage does not alter the Murabaha funding but only affects the profitability; besides, capital adequacy increases the outgoing funding significantly but does not increase stock equity. Murabaha funding is essential to Islamic bank equity. This study implies Murabaha funding are expensed, despite increasing debts in Islamic banks.

The $^{13}C-NMR$ shifts of a series of para-substituted $8-aryl-tricyclo[3.2.1.0^{2,7}]oct-8-yl$ and $9-aryl-tricyclo[3.3.1.0^{2,8}]-non-9-yl$ cations were measured in $FSO_3H/SO_2ClF\ at\-90^{\circ}$ in order to examine whether the ${\rho}^{C^+}$ values can be used as a measure of the geometric influence on the charge delocalization resulting from ${\rho}$ conjugation in rigid tricyclopropylcarbinyl cations. Plot of the ${\Delta}{\delta}^{C+} shifts against the ${\sigma}^{C+}$ constants revealed excellent linear correlation. The 8-aryl tricyclooctyl systems yielded a ${\rho}^{C+}$ value of -5.00 with r = 0.9962. Previous investigation of the 9-aryl-tricyclononyl systems gave a correlation coefficient of r = 0.9948 with a slope of ${\rho}^{C+}$ = -4.95. A fair parallelism exists between the results of $^{19}F-NMR $ studies and the change of ${\rho}^{C+}$ value in these cations. Consequently, it is established that the ${\rho}^{C+}$ value can be used to explain the mechanism of charge stabilization of the rigid cyclopropylcarbinyl cation such as tricyclo $[3.2.1.0^{2,7}]oct-8-yl$ cation.

Purpose: The purpose of this study was to develop a measurement tool for a positive nursing organizational culture and to verify its reliability and validity. Methods: A conceptual framework and construct factors were extracted through an extensive literature review and in-depth interviews with nurses. The final version of the preliminary tool for the main survey was confirmed by experts through a content validity test and a preliminary survey of 40 nurses. Subsequently, the final tool was developed using a validity and reliability test containing 43 preliminary items. The final version of the tool was used with 327 hospital nurses in the testing phase for the main survey to assess validity and reliability. Results: From the factor analysis, 4 factors and 26 items were selected. The factors were positive leadership of the nursing unit manager, pursuit of common values, formation of organizational relationships based on trust, and a fair management system. The entire determination coefficient was 67.7%. These factors were verified through convergent, discriminant, and concurrent validity testing. The internal consistency reliability was acceptable (Cronbach's α = .95). Conclusion: Both the validity and reliability of the scale were confirmed demonstrating its utility for measuring positive nursing organizational culture. It is expected to be used for education, research, and practical performance policies regarding the nursing organizational culture.
