Impact of Alternative Routes and Timing of Dopamine and Mannitol Administrations to Reduce Negative Properties of Extended Cardiopulmonary Bypass on Renal Function in Coronary Artery Operations

Objectives: To analyze impact of alternative routes and timing of dopamine and mannitol administrations to reduce negative properties of extended cardiopulmonary bypass on renal function in coronary artery operations. Methods: Set I (n: 26 individual): Mannitol (1 g/kg) has been introduced to the CPB priming solution. Set II (n: 25 patients): Even during interval among anesthetic induction and operation, 3 g/kg/min of IV dopamine was delivered. Group III (n = 25 patients): 2 g/kg/min IV dopamine was provided among anesthesia initiation and operation conclusion, and 1 g/kg mannitol were added to priming solution for CPB. Furosemide was administered to Group IV (n = 26 cases) when urine production was poor. Results: There would be a substantial rise in the post-operative urine microalbumin/creatinine ratios over all classes (p 0.06), as well as a rise in cystatin-c in Set 1, 2, and 3 (p 0.02). Conclusions: Researchers suggest that combining dopamine infusion (1 g/kg/min) and mannitol (2 g/kg) throughout CPB seems to be the more actual method for preventing detrimental possessions of CPB on renal functioning.

A greedy-tabu approach to the patient bed assignment problem in the Hospital Universitario San Ignacio

Patient Bed Assignment (PBA) consists of assigning patients to hospital beds according to specific requirements such as patient diagnosis, equipment requirements, age and gender policies, among others. We worked in conjunction with the Hospital Universitario San Ignacio (HUSI) with the goal of designing an application to support decision-making during the bed assignment process. We introduced a mathematical model for the PBA. We used Analytic Hierarchy Process (AHP) to determine the weights attributed to each part of the objective function. Due to the long execution time required, we used a Greedy Algorithm and Tabu Search (TS) to optimize the match between the patient’s requirements and the characteristics of the assigned bed. To test the algorithms, we created 15 test instances of various sizes. The results showed that the gap between the value of the objective function resulting from using the Greedy/TS in comparison with the optimal solution is on average 6.2%. Also, the TS takes 84% less time than the MILP for medium and large instances. We collected data from real life instances and compared the actual method with the designed metaheuristic. On average, the value of the objective function resulting from using the proposed Greedy/Tabu algorithm is 8.6% higher.

Islam, Rawls, and the Disciplinary Limits of Late Twentieth-Century Liberal Philosophy

This article tells the archival story of how Rawls invented a hypothetical Muslim state that he called “Kazanistan.” It examines drafts of The Law of Peoples from 1992 to 1998, Rawls's notes, his personal correspondence, and the sources preserved in his archives. I track Rawls's gradual interest in Islam, which resulted in his invention of Kazanistan during the final revisions, in March 1998. Contrary to the aesthetics of rigor and simplicity in ideal theory's methods, Rawls's actual method in his incursion into “comparative philosophy” and Islam was circuitous and contingent. And contrary to ideal theory's self-presentation as emerging from an ahistorical conceptual realm, the idealized abstraction of Islam emerges from Rawls's own history, or from an ideologically limited set of texts, conversations, and political debates about Islam. The genealogy of Kazanistan illustrates how liberal philosophy extracts data from other disciplines to construct other peoples, without regard for the surrounding disciplinary politics.

Modelling Bark Thickness of Norway Spruce (Picea abies Karst)

Background and Purpose: Bark thickness and its share in the volume of roundwood are the most important characteristics of the bark, particularly in the process of timber harvesting, and during scaling of processed logs. Therefore it is very important to have at disposal relatively accurate data regarding these characteristics of bark for particular tree species. The main goal of this paper is to investigate the thickness of the bark and its share in the volume of roundwood of Norway spruce. Materials and Methods: The research was carried out in the area of the Canton 10 of the Federation of Bosnia and Herzegovina and it encompassed 393 trees of Norway spruce from 10 cm to 115 cm of thickness at breast height. Measuring of the mean diameter and double thickness of bark was conducted by section method. In total, 4,647 diameters and bark thicknesses were measured in different relative lengths of stems or in average 10.6 measurements per one stem. Results: As an optimal model for the evaluation of double thickness of the bark of Norway spruce depending on mean diameter of roundwood the function with designated determination coefficient of 0.7142 was selected. The obtained results have confirmed the previously defined relations of investigate characteristics, which are as following: a) with the increase of mean diameter of roundwood (section) double bark thickness is increased from 9.26 mm (thickness class 12.5 cm) to 31.65 mm (thickness class 92.5 cm); b) with the increase of mean diameter of roundwood the share of bark in its volume decreased from 14.26% (thickness class 12.5 cm) to 6.73% (thickness class 92.5 cm). Conclusions: By the actual method of estimating bark thickness or the share of bark in the volume of roundwood of Norway spruce in the forestry of the Federation of Bosnia and Herzegovina a significant error was created which increases with the increase of mean diameter. The obtained results point to the necessity of investigation of these bark characteristics in Bosnia and Herzegovina and represent an inevitable starting point for making adequate tables of bark thickness and its percentage share in the volume of roundwood of Norway spruce.
