Bacterial diseases are an important cause of mortality and morbidity worldwide. The Improper uncontrolled use antibiotics contribute to the bacterial resistance antibiotics.
 It is well known that stop infections by killing or
 
 inhibiting their growth. Antibiotics interfering with critical functions for To overcome this, bacteria developed different mechanisms resist survive. T...
Article history: Received 18 November 2010 Available online 17 February 2011 Interest regarding the challenge-hindrance occupational stress model has increased in recent years, however its theoretical foundation has not been tested. Drawing from the transactional theory of stress, this study tests the assumptions made in past research (1) that workload and responsibility are appraised as challe...
The chapter describes the modeling of a material handling system with the production of individual units in a scheduled order. The units represent the agents in the model and are transported in the system which is abstracted as a directed graph. Since the hindrances of units on their path to the destination can lead to inefficiencies in the production, the blockages of units are to be reduced. ...
Abstract For pulse compression characteristics and not easily affected by noise, linear frequency modulation signal are widely used in underwater acoustic communication. This paper analyzes the characteristics of hyperbolic frequency modulation signal over underwater acoustic channels. Compared with linear frequency modulation signal, hyperbolic frequency modulation has the same performance of ...
Chaos-based communication systems are known to offer advantages that are shared by spread-spectrum communications. One important aspect of performance of any spreadspectrum communication system is the ability to resist jamming. This area of study, however, is not available in the literature. In this paper, the anti-jamming performance of the coherent CSK system is presented. Two common types of...
ایمونوتوکسینها برای درمان سرطان در حال توسعه هستند. آنها از آنتی بادیهای متصل به توکسین مانند اگزوتوکسین پسودوموناس تشکیل میشوند. از طرف دیگر فاکتور رشد اندوتلیال عروقی (vegf) در آنژیوژنزیس تومور نقش دارد و مهار vegfr-2 آنژیوژنزیس و رشد تومور را مهار میکند. هدف از این مطالعه تولید ایمونوتوکسین anti-vegfr2/rpe38، ارزیابی فعالیت سایتوتوکسیسیتی و مکانیسم عملکرد آن در in vitro بود. برای تولید ایمون...
