plagiarism in esl/efl learning contexts has been established as a dynamic and multi-layered phenomenon and has become a topic engaging many researchers in a heated debate in recent years. comparisons of student-generated texts with their source texts have shown that students rely on source texts in their writings and copying is a major strategy used by both l1 and l2 writers. in our country a...
a field experiment was conducted under controlled conditions in completely randomized factorial design with three soil application doses of zn sulphate and drought stress with three replications in chalus, mazandaran province, iran on 1th march, 2015. the treatments were included three amounts of zinc sulphate (0, 30 and 60 kg.ha-1) and three amounts of stress (90, 70 and 50% of field capacity)...
pot marigold (calendula officinalis l.) is a medicinal and ornamental plant. the effect of different concentrations of chlormequat (cycocel), and daminozide, two plant growth retardant, on plant height, flowering, the content of essence and some other traits in pot marigold (calendula officinalis) was assessed. plant growth retardants are commonly applied to limit stem elongation and produce a ...
in the present study, the increase of organic loading rate (olr) influences the biomethanisation of sewage sludge. the research was conducted at technical scale in wastewater treatment plant in tyrowo (near ostróda, poland). it has been shown that the increase of olr, by adding co-substrates, cause the increase of biogas production but not biogas yield coefficient. the substrates used for anaer...
Background and objectives One of the main causes of plant growth and development disorders is the presence of adverse environmental conditions such as drought, which leads to stress in plants and endangers their survival. Recent research, however, recommends the use of soil microorganisms, especially plant growth-promoting bacteria, which are involved in plant growth as well as the nutrient cy...
در این رساله به ارزیابی عملکرد سیستمهای کنترل دیجیتالˆسیستمهای کنترل با نمونه برداری (sampled-data) پرداخته خواهد شد. بطور خاص ، روش pim (نگاشت سیستم ورودی یا plant input mapping) که تکنیکی جدید در طراحی کنترل کننده های دیجیتال با استفاده از طراحی بعمل آمده در زمان پیوسته است ، مورد بررسی دقیق قرار می گیرد. روش نامبرده دارای خاصیت استقنایی پایداری تضمین شده برای کلیه پریودهای نمونه برداری غیرمع...
یکی از مشکلات اساسی در rmmac کلاسیک این است که طراحی سیستماتیک این روش برای plant های ناپایدار امکان پذیر نمی باشد. مشکل اصلی در اینجاست که bpm برای plant های حلقه باز ناپایدار قابل محاسبه نیست. علاوه بر آن، تقسیم سیستماتیک زیرفضای نامعین در rmmac کلاسیک، وابسته به ابزار سنتز µ می باشد و دارای پیچیدگی های نسبتا زیادی است. برای حل مشکلات مذکور، در این تحقیق کنترل تطبیقی مقاوم به روش مدل چندگانه ...
