Study on the nonfatigue and fatigue states of orchard workers based on electrocardiogram signal analysis.

In recent years, fatigue has become an important issue in modern life that cannot be ignored, especially in some special occupations. Agricultural workers are high-risk occupations that, under fatigue conditions over a long period, will cause health problems. In China, since very few studies have focused on the fatigue state of agricultural workers, we were interested in using electrocardiogram (ECG) signals to analyze the fatigue state of agricultural workers.

Evaluation of tractor driving vibration fatigue based on multiple physiological parameters.

The vibration generated by tractor field operations will seriously affect the comfort and health of the driver. The low frequency vibration generated by the engine and ground excitation is similar to the natural frequency of human organs. Long term operation in this environment will resonate with the organs and affect drivers' health.

A new species of the Chinese endemic genus (Collembola: Entomobryinae) described and the first description of amale of .

We describe the male of Sinhomidia bicolor for the first time noting a morphological difference from the female. A new species, Sinhomidia guangxiensis sp. nov.

[Histopathological research and immunofluorescence of AVND virus infection in cultured scallop Chlamys farreri].

The naturally infected scallops Chlamys farreri sampled during mass mortality in summer of 2003 was detected by means of histopathological and MAb-based immunofluorescence assay (IFA). The results of histological examination demonstrated that a series of histopathological changes including cell swelling, basophilic increase, disorder, partial sloughing and excessive sloughing were always observed in epithelia of many different organs, e.g.
