In this study, the effects of boundary influence on flow characteristics Rivers Ala and Orisa were investigated. Soil samples collected from three points each both rivers namely Glory Parish Area (GPA), Olusola Oke (OOA) Fiwasaye; Aran-Orin (AOA), Rore Omu-Aran Respectively. A MGG/KL-DCB Portable Electromagnetic Velocity Meter was used to measure in-situ readings discharge velocity at various p...
Background: Yellow mosaic disease (YMD) transmitted by white fly, Bemisia tabaci is the most persistent and devastating biotic stress worldwide in India resulting reduced productivity of mungbean. At same time yield levels mungbean reached a plateau, which emphasizes importance varieties with improved productivity. Methods: In present investigation, to address this urgent requirement YMD resist...
یون تیوسیانات در پسابهای صنعتی باعث افزایش آلودگی و سمیت آنهامی شود . در این پژوهش حذف یون تیوسیانات توسط جاذب نانو ذرات مغناطیسی آهن اصلاح شده با کمپلکس کیتوسان - آهن (III) بررسی شد .درصدحذف با نانوذرا ت مغناطیسی اصلاح شده به نحو قابل ملاحظه ای بیشتر از درصد حذف با نانو ذرات مغناطیسی می باشد . اثر عوامل مختلف برحذف تیوسیانات از جمله pH، مقدار جاذب، زمان هم زدن، و اثر دما موردمطالعه قرار ...
This study investigated the variation in the pigment, proline, soluble sugar and ion content of three populations of Haloxylon ammodendron in Yazd province. This was carried out using one-year old plants of the same size from each population. Sampling occurred in a factorial experiment conducted using a randomized complete design with five replicates. The results showed that chlorophyll a and t...
Pharmaceuticals as an increasing water contaminant pose major hazards to quality and human health. Hydroxyapatite (HAp) has shown promise in the treatment of many contaminants, although it could be improved. The adsorption capacity silver titanium dioxide nanoparticles doped calcined HAp (AgNPs-TiO2NPs@calcined HAp) for acetaminophen (ACT) Ibuprofen (IBP) was investigated this study. Fourier Tr...
Background: Heavy metals, even at low concentrations, are harmful to human health and environment. Cadmium as a heavy metal is highly toxic and can cause serious threat to living organisms. This research was designed to evaluate the adsorption potential of modified magnetic iron nanoparticles by 2-(5-bromo-2-pyridylazo)-5-diethylaminophenol ligand for the removal of cadmium ions from water solu...
Metal oxide-based adsorbents are quite in for wastewater treatment because of their selectivity, stable structure and very low solubility aqueous systems. To explore the adsorption methylene blue (MB), Mn 3 O 4 -Bi 2 were made using a wet-impregnation technique with various concentrations . The presence contents on surface monoclinic Bi was confirmed through representative scanning electron mic...
Background: Carcinoma of lung has now become increasingly frequent during the last 60 years; this increase is seen in males and especially females. Cytological evaluation from respiratory tract initial investigation along with radiological investigations patients suspected to have pulmonary diseases. The various cytological samples included transbronchial needle aspiration, guided fine aspirati...
اندازه گیری مقادیر کم طلا از نمونه های آبی به روش جذب اتمی شعله ای پس از پیش تغلیط با نانو روی اکسید
طلا فلزی گرانبهاست که به دلیل خواص ویژه و منحصر به فردش همچون مقاومت در برابر هوا، رطوبت و سایش بسیار مورد توجه قرار گرفته است. فراوانی طلا در میان فلزاتی که در طبیعت به حالت عنصر یا آزاد یافت می شوند، بسیار کم است. مقادیر کمی از طلا را می توان در فاضلاب های صنایع جواهرسازی، صنایع الکترونیک و معادن و صنایع آبکاری پیدا کرد. استخراج طلا از فاضلاب این صنایع و استفاده مجدد، از نظر مالی بسیار سودمند...
