Purpose: Anesthesia and airway management for mediastinal masses are challenging and are accompanied by mortality and morbidity. Avoiding the loss of airway muscular tone in mediastinal masses has been confirmed necessary to avoid airway collapse. Sufficient spontaneous ventilation is of paramount importance in order to reduce the rate of mortality and morbidity. Various anesthetics and anesthesia techniques have been used for maintaining spontaneous ventilation and patent airway. In this report, a successful double lumen endobronchial intubation using “subcutaneous dissociative conscious sedation” as a novel method in the management of compromised airway (a case of a mediastinal mass) is presented. Clinical features: A 42 year- old, 62 Kg man was presented for an open biopsy of a middle mediastinal mass. The patient had a history of chest pain, dyspnea, cough, fever and sweats for 2 months. Regarding to the life threatening nature of mediastinal masses resulting from unpredictable events of airway obstruction and the reported cases of deaths after induction of anesthesia in patients with mediastinal masses and regarding to the importance of not losing muscular tone and keeping airway tone intact in patients with mediastinal masses” subcutaneous Dissociative Conscious Sedation (a novel method of anesthesia)”was selected in order to guarantee the safety of the patient and keep the airway secure. Conclusion: Owing to the characteristics of the “subcutaneous dissociative conscious sedation” this method is suggested as an appropriate substitute to general anesthesia for Endobronchial Double Lumen Intubation in mediastinal masses and compromised airway.

Objective: To evaluate analgesic, hypoglycemic, anxiolytic, and anthelmintic activities with phytochemical screening of methanolic extract of Tabernaemontana recurva (T. recurva) whole plants. Methods: The plant parts of T. recurva were collected, dried, powdered and extracted with methanol. Then the extracts were subjected to in vivo analgesic, hypoglycemic, anxiolytic activity in mice model and in vitro anthelmintic activity. Results: The analysis of phytochemical screening confirmed the existence of alkaloid, saponin, tannins, carbohydrate, phytosterols, glycosides and phenol. In analgesic test, a significant level of percentage inhibition of abdominal constriction was observed with concentration of 200 and 400 mg/kg of body weight of extract and this was found better with formalin induced hind paw licking test rather than acetic acid induced writhing test. In hypoglycemic test, it was observed that concentration 200 mg/kg reduced blood sugar level slightly while concentration 400 mg/kg increased glucose level by 22.95%. A significant level of anxiolytic activity was observed for the study plant extract. The extract revealed potent anthelmintic activity at different concentrations. Conclusions: In light, the methanolic extract of T. recurva exhibited excellent anthelmintic, anxiolytic and analgesic activity. This plant showed moderate hypoglycemic effect at lower concentration but higher concentration increased blood glucose level.

Fuzzy Logic is used to derive the optimal inventory policies in the Supply Chain (SC) numbers. We examine the performance of the optimal inventory policies by cutting the costs and increasing the supply chain management efficiency. The proposed inventory policy uses multi-agent and Fuzzy logic, and provides managerial insights on the impact of the decision making in all the SC numbers. In particular, we focus on the way in which our agent purchases components using a mixed procurement strategy (combining long and short term planning) and how it sets its prices according to the prevailing market conditions and its own inventory level (because this adaptivity and flexibility are key to its success). In modern global market, one of the most important issues of the supply chain (SC) management is to satisfy changing customer demands and enterprises should enhance the long-term advantage through the optimal inventory control. In this paper an intelligent multi-agent system to simulate supply chain management has been developed.

传统的回声消除系统无法在嘈杂的双工环境下工作。由于双工信号的干扰,误差信号不能正确地指导滤波器系数的更新。本文中提出了一种基于相关函数的自适应滤波算法,扩展型相关函数LMS(ECLMS)算法。计算机仿真结果显示E-CLMS算法的表现要优于传统LMS算法。然而,ECLMS的收敛速度仍然不能令人满意。为了提高ECLMS算法的收敛速度,本文推出了一种新的正比例步长调整算法,针对自适应滤波器系数的每一个抽头,提供一个合理的步长调整参数。计算机仿真结果证实了正比例扩展相关LMS算法理论的正确性。

A lot of investigations have been done in order to understand the mechanisms of the transport of particulate suspension flow through porous medium. In general, Deep Bed Filtration studies have been conducted to analyse the mechanism involved in the processes of capturing and retaining particles occurs throughout the entire depth of the filter and not just on the filter surface. In this study, the deep bed filtration mechanism and the several mechanisms for the capture of suspended particles are explained then the size exclusion mechanism has been focused (particle capture from the suspension by the rock by the size exclusion). The effects of particle flux reduction and pore space inaccessibility due to selective flow of different size particles will be included in the model for deep bed filtration. The equations for particle and pore size distributions have been derived. The model proposed is a generalization of stochastic Sharma-Yortsos equations. Analytical solution for low concentration is obtained for any particle and pore size distributions. As we will see, the averaged macro scale solutions significantly differ from the classical deep bed filtration model.

The additional diversity gain provided by the relays improves the secrecy capacity of communications system significantly. The multiple hops in the relaying system is an important technique to improve this diversity gain. The development of an analytical mathematical model of ensuring security in multicasting through fading channels incorporating this benefit of multi-hop relaying is still an open problem. Motivated by this issue, this paper considers a secure wireless multicasting scenario employing multi-hop relaying technique over frequency selective Nakagami-m fading channel and develops an analytical mathematical model to ensure the security against multiple eavesdroppers. This mathematical model has been developed based on the closed-form analytical expressions of the probability of non-zero secrecy multicast capacity (PNSMC) and the secure outage probability for multicasting (SOPM) to ensure the security in the presence of multiple eavesdroppers. Moreover, the effects of the fading parameter of multicast channel, the number of hops and eavesdropper are investigated. The results show that the security in multicasting through Nakagami-m fading channel with multi-hop relaying system is more sensitive to the number of hops and eavesdroppers. The fading of multicast channel helps to improve the secrecy multicast capacity and is not the enemy of security in multicasting.
