Objective(s): Polyethylenimine (PEI) is one of the most widely used polymers in gene delivery. The aim of this study was to modify PEI by replacing some of its primary amines with Brevinin 2R (BR-2R) peptide in order to increase the efficiency of gene delivery.Materials and Methods: Polyethylenimine was modified by BR-2R peptide by two d...

In this paper a new approach for the underwater sensor network based on the blue-green laser has been proposed. We describe the application of the underwater sensor network in the undersea exploration, and discuss the difficulties in the traditional the underwater acoustic sensor network. A basic of prototype of underwater laser sensor network has been advanced, which include the architecture o...

The usually constrained resources and lossy links scenarios of Internet Things (IoT) applications require specific protocol suite, as the IPv6 Routing Protocol for Low-Power Lossy Networks (RPL). Due to its flexibility, RPL can support efficiently vertical such environmental monitoring, smart city Industry 4.0. In this paper, we propose a new Objective Function (OF) based on composite metric co...

A modern undergraduate organic chemistry laboratory experiment involving the Suzuki-Miyaura coupling is reported. Although Suzuki-Miyaura couplings typically employ palladium catalysts in environmentally harmful solvents, this experiment features the use of inexpensive nickel catalysis, in addition to a "green" alcohol solvent. The experiment employs heterocyclic substrates, which are important...

An image analysis program and protocol for the identification and enumeration of live versus dead cells of the yeast-like fungus Aureobasidium pullulans was developed for both populations on microscope slides and leaf surfaces. Live cells took up CellTracker Blue, while nonviable cells stained with DEAD Red. Image analysis macro programs running under Optimas software were used to acquire image...

green architecture, or green design, is an approach to building that minimizes harmful effects on human health and the environment. the “green” architect or designer attempts to safeguard air, water, and earth by choosing eco-friendly building materials and construction practices. so, green architecture is building and structure design philosophy that aims at minimal use of non-renewable and/or...

An efficient and green protocol for the synthesis of αaminonitriles derivatives by one-pot reaction of different aldehydes with amines and trimethylsilyl cyanides has been developed using natural alumina, alumina sulfuric acid (ASA), nano-γ-alumina, nanoalumina sulfuric acid (nano-ASA) under microwave irradiation and solvent-free conditions. The advantages of methods are short reaction times, h...
