Review on Silkworm (Bombyx mori)Sex Control in China
An-Ying Xu,Mu-Wang Li,Ping-Jiang Sun,Yue-Hua Zhang,Cheng-Xiang Hou 한국잠사학회 2004 International Journal of Industrial Entomology Vol.8 No.2
Normally, silkworms, Bombyx mori, generate offspring by sexual activity. As we known, the hybrids of the first generation of the silkworm have higher cocoon production than pure lines. During the sericulture production, many processes are related with sex control. For example, sex sorting in the egg grainages, rearing of only male silkworm to save the mulberry leaf consumption and increase silk output and quality. Therefore it is very interested in understanding the sex control of the silkworm in theory and practice. Chinese sericultural scientists have been being engaged in the researches in the fields of artificifial parthogenesis, dispermic androgenesis, sex-limited varieties, sex linkage balanced lethal strain and high temperature sensitive male stocks for several decades and gained substantial achievement. Some of the achievements have been used in the commercial production. In this review, the authors introduced that the methods for control of the silkworm sex, and regulate the silkworm sex ratio according to different producing aim in the world and especially in China.

When calculating the can loss, the fnite element method considering time harmonics needs the working current waveform, and the analytical method considering the harmonic adopts superposition principle. Based on the power conservation law, this paper proposes a method to obtain the can loss that can take into account the time harmonics from inverter and the harmonic loss. The method can obtain the calculation accuracy similar to that of the fnite element method without relying the current waveform of the motor, and has the advantages of simple calculation and saving time. In addition, the method proposed in this paper is used to analyze the can loss under diferent loads, and the infuence law of the can parameters on the can loss is explored. It provides a reference for the determination and optimization of the can loss of the canned permanent magnet synchronous motor under non-sinusoidal excitation.

As a promising anode for sodium-ion batteries (SIBs), cobalt sulfide ( CoS2) has attracted extensive attention due to its high theoretical capacity, easy preparation, and superior electrochemical activity. However, its intrinsic low conductivity and large volume expansion result in poor cycling ability. Herein, nitrogen-doped carbon-coated CoS2 nanoparticles (N–C@ CoS2) were prepared by a C3N4 soft-template-assisted method. Carbon coating improves the conductivity and prevents the aggregation of CoS2 nanoparticles. In addition, the C3N4 template provides a porous graphene-like structure as a conductive framework, affording a fast and constant transport path for electrons and void space for buffering the volume change of CoS2 nanoparticles. Benefitting from the superiorities, the Na-storage properties of the N–C@CoS2 electrode are remarkably boosted. The advanced anode delivers a long-term capacity of 376.27 mAh g? 1 at 0.1 A g? 1 after 500 cycles. This method can also apply to preparing other metal sulfide materials for SIBs and provides the relevant experimental basis for the further development of energy storage materials.
