پروانة دم قهوهای بلوطEuproctis chrysorrhoea (L.) حشره ای برگخوار و پلی فاژ است که به درختان جنگلی و درختان میوه حمله میکند. این پروانه مهمترین آفت درختان بلوط در جنگلهای ارسباران بشمار میآید. برای بررسی میزان خسارت حشره در جنگلهای ارسباران طول دوره لاروی و میزان و درصد تغذیة روزانه ودورهای آن در سنین مختلف لاروی مورد ارزیابی قرار گرفت. بدین منظور از زمان...
Hemophilia A is caused by a deficiency of actor-Vlll procoagulant (NIII) activity. The current treatment by frequent infusions of plasma-derived Nlll concentrates is very effective but has the risk of transmittance of blood-borne viruses (human immunodeficiency virus IHIVI, hepatitis viruses). Use of recombinant DNA-derived Nlll as well as gene therapy could make hemophilia treatment independen...
This paper presents a model of collaborative telelearning and describes how coordination theory has provided a framework for the analysis of actor (inter)dependencies in this scenario. The model is intended to inform the instructional design of learning scenarios, the technological design of the telelearning environment, and the design of intelligent agents to mediate or to support the mediatio...

Various have different control strategies, precisely identifying has become crucial pest is a difficulty in agriculture. Many agricultural professionals interested deep learning (DL) models since they shown promise image recognition. Pest identification approaches literature relatively low accuracy rec...
Wireless Sensor and Actor Networks (WSANs) constitute an emerging and pervasive technology that is attracting increasing interest in the research community for a wide range of applications. WSANs have two important requirements: coordination interactions and real-time communication to perform correct and timely actions. This paper introduces a methodology to facilitate the task of the applicati...
