Introduction:

Nanobiotechnology serves as an imperative technique in the development of clean, nontoxic, and eco-friendly procedures for the synthesis and congregation of metal NPs having the intrinsic ability to reduce metals by specific metabolic pathways. Silver nanoparticles are particularly interesting nanoscale systems due to the ease with which they can be synthesised and modified chemically. Synthesis of silver nanoparticles has been widely researched due to their interesting size and shape-dependent properties [26]. These novel properties can be tailored by controlling their size, shape, composition, structure and crystallinity. Due to their size features and advantages over available anti-microbial properties, chemical imaging ...

Introduction

XX century was characterized with the significant technological progress, which has improved the life of people. Numerous products and services became available, labor and domestic life became easier and more comfortable. However, waste problem is the other side of the technological progress. The solid, liquid and gas waste are formed, and thus land, natural water and air quality degrade. Therefore, in XXI century the research efforts are dedicated to development of methods for sustainable use of water, gas, and solid resources. Wastewater polluted with dye residuals originate from textile, leather and food industry. These industries produce goods that ...

Introduction

It is imperative to note that productivity growth is an aspect that is often used by economists to gauge the performance of an economy. In evaluating the living standards of a country in the long-term, the efficiency with which capital and labor are combined has a significant role to play.

Chinese health and the effects fast food has made over the last 20 years.

The inevitable process of globalization is undoubtedly accelerating the movement of humanity towards progress. A good example – the Asia-Pacific region, where until recently many millions of people lived in absolute poverty. And now, in terms of welfare, the region approaches North America and Western Europe. China is the most obvious example. In 1981 there were 84% of people who lived from hand to mouth (The Wall Street Journal). In 2012, according to Gallup the number of people living below the absolute poverty went down to 7% (Kravtsov). Those millions of people entered the category of the “new Chinese”. This ...
