Surface waters in the Florida Everglades contain high levels of dissolved organic carbon (DOC) compounds. C values of DOC samples collected from the northern Everglades indicate that less than about 23% of the DOC was derived from sugarcane (the dominant agricultural crop in the area), and the amount of DOC from sugarcane was greater during the dry period. Most of the DOC (> 50%) in the norther...
diclofenac sodium as ophthalmic dosage form is used in patients treatment of eye pain, swelling and redness recovering from cataract surgery but it faces the bioavailability limitation of eye drops due to effective protective mechanisms and corneal barrier functions in the eyes. therefore, this investigation was aimed to develop ocular film formulations to achieve controlled drug release. drug ...
Assessment of heavy metals concentrations in aquatic ecosystems can be effective to taking actions to improve the quality of environmental conditions. Therefore, this study was downed to evaluate the heavy metals pollution in water and sediments of water supply points of water treatments in Ahvaz and Mollasani along Karun River and the effect of physico-chemical parameters on these pollutants c...
Heated (20 min at 70 degrees C) amphotericin B-desoxycholate (hAMB-DOC) was further characterized, as was another formulation obtained after centrifugation (60 min, 3000 x g), hcAMB-DOC. Conventional AMB-DOC consisted of individual micelles (approximately 4 nm in diameter) and threadlike aggregated micelles, as revealed by cryo-transmission electron microscopy. For both hAMB-DOC and hcAMB-DOC, ...
The influence of dissolved natural organic matter (NOM) source on copper toxicity was investigated with larval fathead minnows (Pimephales promelas) in reconstituted moderately hard water. Ninety-six-hour static renewal toxicity tests were conducted to investigate an assumption of the biotic ligand model (BLM) that NOM source does not need to be considered to adequately predict copper toxicity....
This study is designed to test the hypothesis that docetaxel [Doc] containing oily core nanocapsules [NCs] could be successfully prepared with a high percentage encapsulation efficiency [EE%] and high drug loading. The oily core NCs were generated according to the emulsion solvent diffusion method using neutral Labrafac CC and poly(d, l-lactide) [PLA] as oily core and shell, respectively. The e...
This paper discusses the feature checking mechanism of interrogative sentences in Japanese and Korean. We first focus on a phenomenon of omitting question markers in informal speech in Japanese and attempt to provide an account for it within the framework of Principles and Parameters approach. We argue that question markers can be omitted only if interrogative features of the sentence can be pr...
چکیده در بخش اول این پروژه دو روش میکرواستخخرا به نامهای میکرواسخخرا امولسیونی با کمک اموا فراصتتتو 1 و میکرواستتتخخرا مای – مای با کمک هوا 2 ، به عنوان دو روش میکرواستتتخخرا بدون حلال پخشکننده 3 ، برای اسخخرا برخی هیتدروکربتنهای آروماتیتک حلقوی 4 از نمونتههای آبتی بهکار گرفخه و پارامخرهای موثری همچون نوع حلال اسختتتتخرا کننده، حجم حلال اسخخرا کننده، میزان نمک، زمان تابش اموا فراصتو ، تددا...
We investigated the effect of dissolved organic carbon (DOC) on hypolimnetic metabolism (accumulation of dissolved inorganic carbon (DIC) and methane (CH4)) in 21 lakes across a gradient of DOC concentrations (308 to 1540 !mol C L). The highly colored nature of the DOC in these lakes suggests it is mostly of terrestrial origin. Hypolimnetic methane accumulation was positively correlated with ep...
