Basic life Support (BLS) following by Advanced cardiac life Support (ACLS) is intended to rescue the patients with acute circulatory or respiratory failure or both. The most important determinant of short and long-term neurologically intact survival is the interval from the onset of the cardiac or respiratory onset to restoration of effective spontaneous functions of these vital activities.It is commonly accepted that every physician, regardless of specialty, should be able to  perform CPR. It must be also emphasized that CPR, almost invariably, necessitates a rapid interventional follow-care with ACLS procedure.Without well-performed basic life Support, advanced cardiac life Support is of no remark-: able benefit, BLS and ACLS are processes that must be performed step by step and with respect to the patient's condition.

A common method for controlling a group of parallel converters in decentralized control strategy structure in an island microgrid, the use is the droop-down characteristics of frequency ω-P and voltage E-Q. However, the problem with using this method is that the reactive power is not properly distributed (in proportion to the capacity of the micronutrients) between the micronutrients, which may lead to overload in the converters. Microgrids may also suffer from dynamic stability problems such as power fluctuations, which can be increased by switching between active and reactive power control. To avoid this problem, the X / R ratio of transmission lines is an important parameter that should be carefully considered in the design of micronutrient controllers. By linearizing and simplifying conditions, the control system conversion function model becomes a single input-single output system, which is efficient enough to show the relationship between control parameters such as slope of droop characteristics and derivative sentences, virtual impedance, and voltage controllers. Using this model, stability conditions for different parameters are analyzed. Also, to improve power distribution stability, common droop strategies are modified by adjusting the slope as well as adding nonlinear sentence sections. This approach reduces the coupling between active and reactive power control and reduces the dependence of power distribution on grid parameters such as the X / R ratio. To evaluate the reliability of the proposed model, the simulation results in a sample island microgrid in MATLAB software are presented.

Introduction: Salmonella Bacterium is not only a causative factor of typhoid fever, enterocolitis, and salmonellosis, but it is also a zoonotic infection. This bacterium is a major health problem throughout the world, and is especially prevalent in developing countries. Therefore, rapid diagnosis of salmonella can prevent its outbreak. Different techniques are used for the diagnosis of  Salmonella bacteria, such as; culture, biochemical, serological, ELISA, Widal, immunofluorescence and molecular methods like PCR and Real time PCR,all of which are difficult, time-consuming, and expensive. Thus, our study was designed to evaluate the LAMP (Loop-mediated isothermal DNA amplification method) for detection of salmonella bacteria.Materials & Methods: In this study, we examined 7 different strains of salmonella.  The DNA was extracted by standard methods and amplified with specific primers by PCR and set of primers for LAMP in single temperature in very simple thermal block made in Iran. The amplified products were detected by gel electrophoresis and LAMP products were visualized by their turbidity with naked eye.Findings: Conventional PCR method for detection of Salmonella needs standard thermocylcer and takes 3 hours, but using  LAMP method, we were able to amplify and detect salmonella in simple thermoblock, taking much less time. After optimization of the process, it was, soon, possible to detect and identify Salmonella typhi bacteria within 90 minutes. This method is also 10 times more sensitive than that of the PCR.Discussion & Conclusion: According to the results, comparing LAMP method for detection and identification of Salmonella with conventional PCR, we have been able to determine the simplicity, speed and the superior sensitivity of the LAMP method. This Method is more simple, faster and cheaper. Non-dependence of cycle's temperature and thermo-cycling and replacement with one thermo block which is very simple, inexpensive and made inside the country, can be considered another advantage of the LAMP method.

Background: Recently, the surgical methods are used in patients with anterior cruciate ligament rupture and have been associated with successful results. There are different results in the term of using of the surgical methods for anterior cruciate ligament that often is associated with some complications such as infection, static laxity, remaining the pain, need to recurrence surgery, and limitation in the range of motion. Therefore, in this study, we aimed to compare outcomes of anterior cruciate ligament reconstruction with the fixed Loop and the adjustable Loop. Methods: This cross-sectional study was done on 60 patients undergoing anterior cruciate ligament reconstruction referred to Kashani Hospital of Isfahan, Iran, from March 2017 to February 2019. Also, this study was approved in the Isfahan University of Medical Sciences, Isfahan, Iran. 30 patients were assigned to a fixed Loop and 30 patients under the adjustable Loop method. Postoperative outcomes were compared with the fixed Loop group and the adjustable Loop group. Results: The frequency of static laxity below 8 mm in the fixed Loop group was 83. 3% and the frequency of static laxity below 8 mm in the adjustable Loop was 76. 7%. There was no significant difference between the fixed Loop group and the adjustable Loop group based on static laxity. Also, no infection was seen in the fixed Loop group and the adjustable Loop group. There was no significant difference between the fixed Loop group and the adjustable Loop group in terms of range of motion and knee score before and after surgery. After surgery, 96. 7% of the fixed Loop group and 86. 7% of the adjustable Loop group returned to normal activity. There was no significant difference between the fixed Loop group and the adjustable Loop group in terms of return to normal activity and satisfaction. Conclusion: Using the fixed Loop is effective, useful, and with low-complication for the patients with anterior cruciate ligament and also using the adjustable Loop grafts is effective, useful, and with low-complication for the patients with the anterior cruciate ligament rupture.

One of the main components of competition in the current competitive environment is supply chain; therefore, organizations need to have a reliable supply chain to increase efficiency and effectiveness. Moreover, due to the increase in environmental pollution and the requirements imposed by the governments to harness polluting activities, organizations are obliged to follow green supply chain practices that account for environmental considerations along with economic aspects. hence, in this study, a bi-objective model for a green, closed-Loop supply chain under demand uncertainty is proposed which takes into account environmental consideration and economic aspects. Another important aspect of the supply chain network design is the concept of uncertainty. Due to societal and political evolutions and the scarcity of raw materials in the decision-making horizon, uncertainty is a significant measure in the models of supply chain. Indeed, in this study, the model was developed for a supply chain under uncertainty so that more compatibility with real-world conditions would be achieved. The results show that considering uncertainties makes the model more flexible. The advancement of technology and unpredictable behaviors of customers in markets have created a very complex competitive atmosphere. To evaluate the performance of the developed model, the case study of the Iran Transfo Company is considered.
