مقدار تبخیر و تعرق حقیقی مزرعه یونجه واقع در باجگاه بوسیله روش تعادل آبیاری در 9 کرت آزمایشی و دولیسمتر از نوع وزنی بمنظور تعیین آب مصرفی گیاه یونجه تعیین شد. در طول مدت آزمایش مقدار آب موجود در خاک بوسیله نمونه برداری وزنی از خاک و دستگاه نوترون متر تعیین و مقدار تشعشع رسیده از خورشید بزمین و ساعات آفتابی روز نیز اندازه گیری شد. مقدار تبخیر و تعرق پتانسیل بوسیله روشهای modified blaney-criddle ...
The present work focuses on preparation and characterization of erythromycin loaded gelatin nanoparticles through nanoprecipitation method. The procedure consists of the addition of the aqueous gelatin solution to the non-solvent phase containing Lutherol F127. Three different measures of cross-linker and polymer concentration were also examined, and the optimum concentration was found. The mor...
Cellulose acetate (CA) nanoparticles were combined with two antimicrobial agents, namely lemongrass (LG) essential oil and Cu-ferrite nanoparticles. The preparation method of CA nanocapsules (NCs), with the two antimicrobial agents, was based on the nanoprecipitation method using the solvent/anti-solvent technique. Several physical and chemical analyses were performed to characterize the result...
The digital gates are basic electronic component of any digital circuit. Digital circuit should be simplified in order to reduce its cost by reducing number of digital gates required to implement it. To achieve this, we use Boolean expression that helps in obtaining minimum number of terms and does not contain any redundant pair. Karnaugh map (K-map) and Quine-McCluskey (QM) methods are well kn...
Ferroelectric polymer nanoparticles of poly(vinylidene fluoride) (PVDF) were prepared by dialysis nanoprecipitation. Particles with mean diameter 230 nm show piezoelectric response as observed Piezoresponse Force Microscopy (PFM). The origin this ferroelectric behavior has been attributed to the presence ferroelectrically active crystalline phases PVDF in (mainly ? and ? phases) demonstrated di...
BACKGROUND AND OBJECTIVE Nanotechnology offers the possibility of creating multi-functional structures that can provide solutions for biomedical problems. The nanoprobes herein described are an example of such structures, where nano-scaled particles have been designed to provide high specificity and contrast potential for optical detection of cancer. Specifically, enzymatically activated fluore...
