Using Alfalfa silage as research materials, the research discusses the prediction of Near Infrared Spectroscopy (NIRS) on chemical compounds 121 samples of alfalfa silage. The results are as follows: the NIRS models of DM, CP, WSC have been set up. The RPD value for cross validation and validation are all above 2.5. The results show that the NIRS can accurately evaluate nutritive value of alfalfa...
Using 42-inch plasma screens and showing four kinds of content, we experimentally evaluated the relationship between TV viewers' emotional state and selected physiological and psychological indices. Our results indicated that near-infrared spectroscopy (NIRS) and low frequency/high frequency ratio (LF/HF), representing nervous system activities, are potentially useful indices for evaluating emotional...
In the present paper we combined two different non-destructive techniques to detect the water content spatial variation in a porous material. The main goal of this work was to verify the ability of radar “early time” signals, using the proton density values measured with the unilateral NMR (Nuclear Magnetic Resonance) technique, in order to detect the spatial distribution of water in the subsurface...
In this paper the effect of loading absorbing material on the reverberation chamber is mainly discussed, including distribution function, correlation coefficient and loading factor. The absorbing material's number and location are analyzed in detail. Based on the statistics, in the reverberation chamber, a certain amount of load can improve the performance, and the different location load makes a...
As student satisfaction surveys are a primary method of evaluating university faculty teaching performance, it is essential to develop an understanding of the factors driving course evaluation. Here we discuss experiments conducted to investigate the value of various service actions in the classroom environment. In particular, we focus on the offering of excitement needs such as giving candy, humor,...
In order to improve the quality of teaching and learning, teachers and researchers today have created the Web-based teaching (WBET) environment to facilitate L2 learners to master L2 better. Web-based English teaching and learning in China has been developing very fast. And this paper deals with the study of Second Language Acquisition (SLA) and WEBT, and the problem of how to facilitate SLA theories...
Corn stalk is a primary crop residue for biomass used as fuel, feedstock and material. However, it is difficult to transport corn stalk at a low cost due to its wide distribution in China. In this study, cellulose, hemicellulose and lignin contents of 13 different varieties of matured corn stalks from Beijing, Liaoning, Shandong, Hubei, Shanxi and Chongqing were measured. Compression tests were executed...
Sanchi is a rare and unique Chinese medical material with extremely high medical value. However, it is often vulnerable to root rot during factitious reproduction. A research, taking Sanchi no-tillage soil and root rot plants as study targets with the purpose to monitor the amounts of microbe colonies and strains in soil around Sanchi roots, has been carried out. The result showed that, although the...
Influence of soil organic matter (SOM) on the adsorption, desorption and transport of polycyclic aromatic hydrocarbons (PAHs) has already been given full investigation in soils. In this paper, High Performance Liquid Chromatography (HPLC) was used to detected and elucidate aqueous leaching of PAHs in different types of soil with soil columns, which enhanced understanding on transport of PAHs appreciably...
There is evidence that different learning styles require diverse modes of communication. Based on 377 completed standardized questionnaires this study contributes to this field of research. To test the relation between learning aids and learning styles double coded data is analyzed by applying a multiple correspondence analysis. Further, impacts of extrinsic motivation, self-efficacy, subject-value,...
The Signals and Systems Concept Inventory is an extremely useful assessment tool that has been widely used and analyzed. The authors have applied it in a variety of situations outside its typical usage. These situations include comparing international students to US students, introducing concept inventories to international faculty, supporting an ABET evaluation report, evaluating the effect of electives...
In rapidly changing knowledge society, teachers should study continuously to use ICT (Information and Communication Technology) in education. It is expected from today's teachers to use ICT innovatively and also to be tool builders, not just tool users. In this article are presented the research results of survey conducted in Osjecko-baranjska county dealing with factors influencing the innovative...
This paper reports the feasibility of using two Malaysian agricultural residues without modification; unmodified sugarcane bagasse (UMSCB) and unmodified coconut coir (UMCC) for the removal of Cd(II) from aqueous solution under different experimental conditions. Effect of various process parameters; contact time, initial metal ion concentration and pH have been studied. The maximum Cd(II) adsorption...
An anionic MgAlNO3 layered double hydroxides (MgAlNO3-LDH) with Mg/Al molar ratio 4∶1, was investigated for its ability to adsorb an anionic dye, Reactive Orange 16 (RO16), with the objective of evaluating its suitability as an adsorbent. The experimental data were analyzed by the Langmuir and Freundlich adsorption models. Equilibrium data fitted well with Langmuir model for the concentration range...
Phenolic, flavonoid and tannin content of dried Pereskia bleo were investigated using the well established method via UV-Vis Spectrometry. Pereskia bleo has phenolic content the highest followed by flavonoid and tannin content. A study of antioxidant activities of dried sample of Pereskia bleo was carried out by using 2, 2-diphenyl-1-picrylhydrazyl (DPPH) assay. The plant shows moderate antioxidant...
This thesis puts forward 11 main influence factors which may have impact on the informatization construction by identifying the internal and external influence factors. And this paper processes the surveyed data of 12 enterprises in northeast area based on grey relational analysis according to the gray character of Enterprise's cognitive to some of the influence factors, and it calculates the correlation...
This work deals with the modeling and simulation of the fretting hysteresis loop. Fretting represents a relative cyclic motion between two surfaces, having a non-uniform distribution of local relative displacement at their contact. Fretting damage is a complex contact phenomenon leading to crack initiation and/or material removal. The shape of the fretting hysteresis loop (loop-like variation of the...
