The detection limit is one of the most important performance parameters for bioanalytical techniques. Here we present a generic method to estimate biomolecular assays based on step-by-step analysis assay procedure. Enzyme-linked immunosorbent (ELISA) used here as an example; however, much information presented in this article may be applied other types and analytical A clear understanding what affects can help researchers evaluate different bio-analytical techniques properly, design better...

In this study, we investigated the interaction between five biorelevant molecules and citrate-capped gold nanoparticles using dynamic light scattering, ζ-potential analysis, UV-vis absorption spectroscopy, transmission electron microscopy. The biomolecules are bovine serum albumin (BSA), two immunoglobulin G (IgG) proteins, M (IgM), a polysaccharide molecule, hyaluronan. BSA, IgG, IgM high abundance proteins in blood. Hyaluronan is major component of extracellular matrix. An abnormal level...

Technological trajectories provide valuable information on technological development as well its potential impact. Using 3D printing technology a case study, this paper maps the trajectory of and explores contribution various knowledge sources (from both geographical perspectives). Based patent citation analysis, our results show that there was main concentrated between 1998 early 2000s, indicating lock-in situation. However, great diversification can be observed after mid-2000s. The U.S....

Based on the panel data of 30 Chinese province in 2005–2018, this paper quantifies agricultural carbon reduction efficiency (CRE), using slack-based measure (SBM)-data envelopment analysis (DEA) model with undesired outputs (SBM-DEA <math xmlns="http://www.w3.org/1998/Math/MathML" id="M1"><msup><mrow /><mrow><mi>∗</mi></mrow></msup></math> ), and empirically tests that development land circulation market directly affects CRE, indirectly CRE via scale operation farmland. The results show...

Since the industrial revolution, concentration of greenhouse gases (GHGs)has been increasing steadily. It is to be noted that China emitted 27% world’s GHGs in 2019, making it most significant contributor climate degradation. The key objectives this investigation are ascertain N-shaped association between CO 2 emissions and economic growth presence energy use domestic government health expenditures. In addition, research inspected role Belt Road Initiative through globalization China. This...

The gentle development of the economy is an important link to realize sustainable in a holistic way. In recent years, due notable decline scale exports and investment, China’s economic growth has decreased significantly, consumption become main force driving growth. Promoting problem current China. this study, ELES model was adopted analyze how structure affected by income among rural residents results show following: (1) significant impact on structure, their behaviors conform “mental...

In the last few decades, emerging hyper-competitive era has increased demand of information system and technology on human resource management for competitiveness. The revolution is completely rapidly redefining way things are done in almost every field activity. Many firms looking utilizing two elements (human resources system) as strategic weapons to compete. particular, demonstrated that referred (HRIS). HRIS an integrated mostly used collect data, govern, record deliver present data...

The CPC Central Committee Document No. 1 several times in the State Department stated that we will steadily push forward agricultural insurance policy experimental work to speed up development of various forms, multi-channel insurance. Agricultural insurance, however, due natural disasters, leading high-risk nature wishes farmers and companies, low purchase show a high rate "effective demand is insufficient, products short supply" situation, effectiveness risk compensation cannot fully...

Since the advent of virtual reality technology, great changes have taken place in modern education and training. It conducts an in-depth study its fundamental cause, that is, training method has distinct advantages over traditional method. The electric power skill platform based on technology was established this paper. Three-dimensional digital modeling high-risk, invisible, inaccessible scenarios industry had been structured by computer system, order to construct immersive environment...

ESG performance has a positive influence on the long-term sustainable development of both firm and society. LA is concerned about relationship among humans, buit, nutural environments, so it especial importance to study what firms are supposed do in practice. This paper made detailed discussion each responsibilities respectively accordance with distinctive characteristics industry. might have two possible implications for literature ESG: (1) an industry-based approach theoretical realistic...

By using Event-Study Analysis, the paper studied empirically about market reaction of M&A real estate listed companies from 2007 to 2008 in China. The results demonstrated that it has a positive income effect short term, nevertheless, such non-related is overwhelming stronger than related ones. In study factors affected through Regression, we can see there asset debt ratio, return on net assets and total turnover; by contrast, negative leverage, proportion property rights Tobin Q. greatest...

Abstract Brassinolides (BRs) are phytohormones that play numerous roles in a plants’ response to environmental stress. While BES/BZR transcription factors essential components BR signaling, their role regulating postharvest fruit responses cold stress is largely unknown. In this study, the application of 24-epibrassinolide (EBR) peaches alleviated chilling injury (CI) during storage. We further characterized key gene, PpBZR1 , which regulates peach resistance. Transient expression showed...

Based on the conditions of product market competition, this paper discusses impact mechanism tax preference innovation output enterprises, and takes listed companies strategic emerging industries in 2009-2016 as research sample to test enterprise innovation. The regulatory effect competition is analyzed. results show that, first all, there an inverted U-shaped relationship between but intensity has not reached inflection point curve, incentive dominant supporting obvious. Secondly, weakens...

The selection and evaluation of urban management modernization indicators should be coordinated with the system as a whole.Through expert method to explore various influencing factors modern city management, using Delphi divides these into concept system, means methods modernization, benefit four main factors, namely level indicators, then use brainstorming select two weights.By applying fuzzy comprehensive theory method, quantitative construction is carried out.According this considering...
