The eco-friendly compounds especially plant extracts have emerged as green corrosion inhibitors for metals and alloys. inhibiting impact of Roselle extract on Cu-Zn alloy in 1M HNO3 solution was studied by weight loss, electrochemical impedance spectroscopy (EIS), potentiodynamic polarization (PDP). It found that acts a good mixed-type inhibitor acid solution. rate decreases with increasing the...

This work was carried out during the two seasons of 2008 and 2009 aiming to study the effect of different levels of cattle manure and biofertilizers (phosphorein and/or nitrobein) as well as their interactions treatments on the growth, sepals, seed yields and some chemical constituents of roselle plants. The obtained results show that all levels of cattle manure and inoculated biofertilizers an...

cladophora and enteromorpha are the filamentous green-algal genuses that have a widespread distribution in caspian sea coast. the aim of this study was to assess the antimicrobial activities of cladophora and enteromorpha in south of caspian sea. antibacterial activities of hydroalcoholic extracts of five different gram negative and positive bacteria including staphylococcus aureus, bacillus su...

The antimicrobial properties of dextrose-encapsulated gold nanoparticles (dGNPs) with average diameters of 25, 60, and 120 nm (± 5) and synthesized by green chemistry principles were investigated against both Gram-negative and Gram-positive bacteria. Studies were performed involving the effect of dGNPs on the growth, morphology, and ultrastructural properties of bacteria. dGNPs were found to ha...

A study was conducted using LabPlant SD-06 Spray Dryer to produce spray-dried rosellepineapple powder. Roselle calyces and pineapples were extracted under optimum condition. Three different maltodextrin DE 10 concentrations (3%, 5% and 10%) were added (w/w) as the encapsulating agent prior to spray drying. Inlet temperatures were varied at 140 C, 160 C and 180 C respectively and the outlet temp...

Physicochemical, nutritional and functional properties of protein fractions and protein isolate (RSPI) from Roselle seed were investigated. The protein content was 91.50, 93.77, 81.55, 71.30 and 40.83% for RSPI, globulin, albumin, glutelin and prolamin, respectively. The functional properties were variable among samples. Glutelin possessed the highest water holding capacity and albumin the lowe...

The pace of modern life dwellers in big cities worldwide increases the demand for fast food or ready-to-cook meals. Dal curry is a common and popular meal item Bangladesh, but its long cooking time needs to be reduced satisfy consumer’s needs. So, this study aimed at developing analyzing mixed dal powder. Samples were prepared with 100% lentil (control), 25% green gram 75% (S1), black (S2), 50%...

conclusions this work gained satisfactory results in developing a nutritionally fortified and palatably accepted papads using purslane leaves. background papads are cereal or legume based preserved products rich in proteins. they are consumed after deep fat frying as a side dish in india. in the present work, the traditional savoury was chosen for value addition with green leafy vegetables i.e....

abstract background: the invasion of microorganisms into the bloodstream and spread to different parts of body can cause disruption the functions of vital organs and even death. the proper and prompt treatment is essential and can significantly reduce morbidity and mortality rates. this study aimed to determine the frequency and the antimicrobial susceptibility of bacteria isolated from blood c...
