We investigated the relationships of the two immune-regulatory plant metabolites, salicylic acid (SA) and pipecolic acid (Pip), in the establishment of plant systemic acquired resistance (SAR), SAR-associated defense priming, and basal immunity. Using SA-deficient sid2, Pip-deficient ald1, and sid2 ald1 plants deficient in both SA and Pip, we show that SA and Pip act both independently from eac...
شوری خاک یکی از مهمترین عواملی است که باعث کاهش چشمگیر بهرهوری محصول در باغات پسته در استان کرمان شده است. در این پژوهش، با استفاده از ستونهای خاک آزمایشگاهی، تاثیر استفاده از مواد اصلاحکننده مختلف بر احیای یک خاک شور آهکی بررسی شد. تیمارها شامل: الف) آب آبیاری، ب) آب آبیاری+ گچ مخلوط شده با خاک سطحی و ج) گچ محلول در آب و همچنین ج) اسید سولفوریک رقیق شده بود. آبشویی خاک بصورت متناوب و تا ...
SAR-BM3D is one of the state of the art despeckling algorithms for SAR images. However, when tackling with high resolution SAR images, it often has an unsatisfying despeckling performance in the homogeneous smooth regions, together with a high time complexity. In this paper, a novel downsampled SAR-BM3D despeckling approach combined with edge compensation is proposed. The proposed algorithm con...
Airborne SAR systems allow a flexible ground mapping with high geometric resolution, independent from daytime and weather conditions. This offers the opportunity of using this technology for the analysis of built-up areas. However, the oblique SAR illumination limits the visibility of certain objects in urban areas depending on the viewing direction. Especially at building locations different S...
In this paper SAR raw data and SAR image data compression is addressed. For SAR raw data compression we suggest a modified FFT-BAQ. Significant advantages in performance are achieved compared to the standard BAQ and integration in the processing chain is feasible to reduce computational requirements. SAR image compression is mainly performed in wavelet domain. Depending on the application a con...
در مناطق خشک و نیمه خشک، تصفیه پساب و استفاده مجدد از آن به عنوان یک عامل مهم در برنامه ریزی منابع آب به شمار می رود. برخی پژوهش گران بر این باور هستند که استفاده از پساب تصفیه شده در کشاورزی یک راه کار بسیار مناسب است زیرا هم عناصری که از خاک توسط گیاهان خارج شده به خاک باز گردانده میشوند و هم خطر آلودگی محیط زیست و منابع آب کاهش پیدا میکند. امکان استفاده از پساب به عنوان آب آبیاری نیاز به برر...
NY-SAR-35 is a cancer/testis (CT) antigen that was identified by serological analysis of recombinant complementary DNA expression libraries. The gene encoding NY-SAR-35 is located on the × chromosome and is aberrantly expressed in a number of cancer types and germ cells, such as those in the testes, but not in normal tissue. It has been reported that treatment with a demethylating agent induced...
in recent years, synthetic aperture radar (sar) images have played an important role in the detection and monitoring of ground targets because of their advantages such as independence from climatic conditions and sensitivity to the target geometry. the complexity of sar imaging sensors, especially in the conversion process from raw data to image, has made it difficult to interpret the behavior ...
Polarimetric Synthetic Aperture Radar (Pol.-SAR) allows us to implement the recognition and classification of radar targets. This article investigates the arrangement of scatterers by SAR data and proposes a new Look-up Table of Region (LTR). This look-up table is based on the combination of (entropy H/Anisotropy A) and (Anisotropy A/scattering mechanism α), which has not been reported up now. ...
