Air pollution is a substantial menace, especially in industrialized urban zones, which affects the balance of environment, life vital organisms and human health. Besides main causes air such as dense urbanization, poor quality fuels vehicle emissions, physical environment characteristics play an important role on quality. Therefore, it to understand relationship between natural This study exami...
Wilting is a common symptom in plants responding to drought stress. Early wilting detection is of high importance for crop precision management. However, it is challenging to develop a reliable measurement technology. This study presents a sensing method based on three-dimensional (3D) images that are generated by a laser scanner. A leaf wilting index (LWI2DFT) is defined from the spectrum of a...
Here, we present PatMatch, an efficient, web-based pattern-matching program that enables searches for short nucleotide or peptide sequences such as cis-elements in nucleotide sequences or small domains and motifs in protein sequences. The program can be used to find matches to a user-specified sequence pattern that can be described using ambiguous sequence codes and a powerful and flexible patt...
UNLABELLED Thermal sensation has a large influence on thermal comfort, which is an important parameter for building performance. Understanding of thermal sensation may benefit from incorporating the physiology of thermal reception. The main issue is that humans do not sense temperature directly; the information is coded into neural discharge rates. This manuscript describes the development of a...
The microclimate model ENVI-met (V4) was used for predicting the effects of different systems of planted pergolas on the microclimate of an atrium. The model was firstly validated using experimental data and then used for different cases studies. The microclimate measurements were carried in a real construction project of a hydroponic pergola at Kostakii Campus of the Technological Education In...
Abstract. Northern India is a densely populated subtropical region with heavy aerosol loading (mean optical depth or AOD ?0.7), frequent heat waves, and strong atmosphere–biosphere coupling, making it ideal for studying the impacts of aerosols temperature variation in latent flux (LH) evaporative fraction (EF). Here, using situ observations during onset summer monsoon over semi-natural grasslan...
Frequent extreme heat events cause major financial losses for the avocado industry. Shading nets are used to protect crops from harsh environmental hazards. To determine their ability improve photosynthetic performance under in avocado, we examined impact of a resilient high-density silver 60% shading net on mature ‘Pinkerton’ trees during such conditions. We hypothesized that reduced solar irr...
abstract evapotranspiration and plant water absorption reduce when exposed to water stress and this reduction results in an increase in leaf temperature. to determine the effect of water stress on leaf temperature and timing of irrigation using leaf temperature, a research was conducted on the research and education greenhouse production center of islamic azad university, isfahan branch (kh...
یکی از کاربردهای تصاویر ماهوارهای، محاسبه دمای سطح زمین (LST) و استفاده وسیع این پارامتر در تخمین دمای هوا (Tair)، تخمین دمای پوشش گیاهی (Tcanopy)، بررسی تاثیر تنشهای محیطی و مدیریتی بر گیاهان و غیره است. تعیین LST به کمک تصاویر ماهوارهای از طریق الگوریتمهای مختلفی انجام میشود که هر یک به تناسب دادههای موجود و شرایط اقلیمی، دارای مزایا و معایبی هستند. در این پژوهش به منظور تخمین دمای پوشش...
Urban Heat Islands (UHIs) and Cool (UCIs) can be measured by means of in situ measurements interpolation methods, which often require densely distributed networks sensors time-consuming, expensive many cases infeasible. The use satellite data to estimate Land Surface Temperature (LST) spectral indices such as the Normalized Difference Vegetation Index (NDVI) has emerged last decade a promising ...
