These are former communist countries which have been going through the transition from centrally-planned economies to open market economies over the past 25 years. During the transition process, structural reforms were conducted to transform the banking sector into a sector suitable for open market economy. These reforms are considered to be the most successful ones in the region. Before the Global Financial Crisis of 2008-09, the economies of the three selected countries were experiencing credit booms. The aim of this research was to examine how the banking sector is performing on an aggregated level years after the crisis and whether the performance is better or worse compared to the pre-crisis period. The findings show that the banking sector was performing better before the crisis in all three countries. After the crisis, the three countries ex...

Nanomedicine offers a solution for their major limitations, including poor solubility, volatility, and non–controlled release, preventing their clinical use. Methods Here, we developed a novel delivery system by nanoformulations that were prepared by impregnating savory essential oil (SA) into mesoporous silica nanoparticles (MSNs). The nanoformulations were characterized and examined for their anticancer activities on cancer cells (HepG2 liver and HL60 leukemia cells) and MRC5 normal cells. We further tested the mechanisms of action and possible molecular targets against HL60 cells. Results The results demonstrated that SA was governed by nanoformulations under the dual–trigger release of pH/glutathione, and it typically fit the Korsmeyer–Peppas kinetic model. The nanoformulations enhanced the anticancer effect against HepG2 cells and HL60 cells compared to SA but were less cytotox...

The method was based on ion-pair complexation between SC and sodium tetraphenylborate (Na-TPB) or phosphotungstic acid (PTA), embedded into a pencil-fabricated graphite sensor electrode coated with poly(vinyl chloride, PVC) matrix, which is pre-plasticized with two different pre-studied plasticizers. The modern fabricated electrodes have a proven fast near-Nernstian response for SC over the concentration range of 1.0 × 10−6 to 1.0 × 10−2 and 1.0 × 10−5 to 1.0 × 10−2 M, with LODs of 6.5 × 10−7 and 5.5 × 10−6 over a pH 3–6 for (SC-TPB)- and (SC-PTA)-based membrane sensors, of O-nitrophenyl octyl ether (O-NPOE) and dioctyl phthalate (DOP), respectively. The selectivity coefficients for different interferents,...

Four rapid, simple and cost-effective stability indicating spectrophotometric methods were used for estimation of MDF in the presence of its acidic degradation product, namely; ratio difference (RD), first derivative of the ratio spectra (1DD), mean centering (MCR) and ratio subtraction method (RS). These methods were validated according to ICH guidelines and all methods revealed a good linearity in concentration range of (5-30 µg/mL) in addition to a good accuracy and precision with mean percentage recovery of 99.97 ± 0.305 for (RD), 100.10 ± 0.560 for (1DD), 100.02 ± 0.483 for (MCR) & 99.18 ± 1.145 for (RS) method. Specificity of the proposed methods was assessed and MDF was determined in the presence of up to 80% of its acidic degradation product for RD, 1DD, MCR and RS methods. The proposed methods were successfully applied...

PEGylated MWCNTs were created and used as a carrier for targeting the antineoplastic drug Ixazomib to myeloma cancer cells (abnormal plasma cells). Ixazomib (MLN2238) was covalently encapsulated into functionalized carbon nanotubes modified with polyethylene glycol (PEG 600) to obtain MWCNTs-PEG-MLN2238. The Ixazomib@ MWCNTs-PEG composite shows promising results as an effective nanocarrier and using a small amount of MWCNTs-PEG-Ixazomib that has a low toxicity compared with that of Ixazomib alone. A multifunctional MWCNTs-PEG-Ixazomib composite is used to test biological effects on multiple myeloma cell lines RPMI 8226 using the MTT assay to enhance treatment efficiency. The cytotoxicity of free Ixazomib citrate (69% cell viability of RPMI8226 cells) was higher than that of MWCNTs-PEG-Ixazomib (91% cel...

We present some examples of what disclosure looks like from forward-thinking companies that have been engaging in tremendous efforts to protect and preserve nature. Our justification for this paper is to provide guidance and encourage other companies to disclose transparently. We believe that B/E accountability is essential in post Covid-19 reporting as the lack of valuing, promoting and investing in biodiversity is considered to be one of the main drivers of the Covid-19 pandemic. The study's sample is the Top 200 companies from the Fortune Global with the years 2012, 2014 and 2016 and companies' websites in 2019. We believe that our paper is providing some guidance on how to repair nature and eliminate biodiversity loss. This is because organisations are reliant on natural capital resources for survival. Also, biodiversity loss and extinction can significantly affect social, economic and financial viability for survival. Our results have some implications for practitioners, policymakers and academics.

While companies’ business grew rapidly, attention and recognition on corporate social responsibility has gradually been attracted and put on a vital strategy position. It has been proofed to be a crucial way that enterprises share their social responsibility actively in order to enhance their competitive advantage. With more and more enterprises knowing how important social responsibility is for their development, they released a new method which is called sustainability report to show them determine and confidence to take social responsibility.This thesis can be divided into six parts. The first part is about introduction and background. The second part is literature review. The third part is the development of hypotheses. The fourth part is research method and the fifth part is a conclusion. The last part is the reference.

This project consists of a set of lessons for teaching Arabic media for non-native speakers of Arabic. The goal of this project is to assist both Arabic teachers and learners in traditional and distance Media classroom in learning and teaching. For this reason, lessons are full of visual materials and electronic exercises that focus on the usage of the most frequent Arabic verbs, vocabulary, and collocations that are used in Arabic media. In each lesson there are a few numbers of digitalized materials and realia resources which were selected carefully from different Internet sites such as BBC, Al-Jazeera, youtube, and some other caricatures’ sites. This project is user-friendly. It is a quick source that are pedagogically designed to provide AFL teachers with ready made lessons in media to teach their students either in class or online. It also gives a hand to learners who...
