A Research on Senior People Online Consumption in China-From Perspective of Providing Technology Support

While the internet skills of the elderly is no longer a big problem,it is still necessary to further improve the online shopping experience and activity of the elderly.Evidently,the frequency of seniors shopping online is not nearly as high as the younger generation,as the elderly online shopping frequency is still calculated by weeks.People with higher education and younger age are more likely to accept technology products and understand how to use them,but people with lower education and older age will find it harder to use technology product.The majority of the elderly have a vision for the further development of technology to help them.This study shows that the elderly group shopping demand is large,but when the majority of the elderly choose offline consumption,the option of just a simple online solution is insufficient.Some shopping apps have made improvements in such aspects as font enlargement,color contrast enhancement and simplified operation steps.However,these improvements only solved the superficial problems,and failed to consider and solve the problems based on the experience of the elderly.

Tea Production Response to Seasonal Rainfall Variability: Evidence from Rwanda

Tea is a very important cash crop in Rwanda, as it provides crucial income and employment for farmers in poor rural areas. From 2017 to 2020, this study was intended to determine the impact of seasonal rainfall on tea output in Rwanda while still considering temperature, plot size (land), and fertiliser for tea plantations in three of Rwanda’s western, southern, and northern provinces, western province with “Gisovu” and “Nyabihu”, southern with “Kitabi”, and northern with “Mulindi” tea company. The study tested the level of statistical significance of all considered variables in different formulation of panel data models to assess individual behaviour of independent variables that would affect tea production. According to this study, a positive change in rainfall of 1 mm will increase tea production by 0.215 percentage points of tons of fresh leaves. Rainfall is a statistically significant variable among all variables with a positive impact on tea output Qitin Rwanda’s Western, Southern, and Northern provinces. Rainfall availability favourably affects tea output and supports our claim. Therefore, there is a need for collaboration efforts towards developing sustainable adaptation and mitigation options against climate change, targeting tea farming and the government to ensure that tea policy reforms are targeted towards raising the competitiveness of Rwandan tea at local and global market.

Green Production Technology of the Monomer of Nylon-6： Caprolactam

After two decades＇ endeavor, the Research Institute of Petroleum Processing （RIPP） has successfully de- veloped a green caprolactam （CPL） production technology. This technology is based on the integration of titanium silicate （TS）-I zeolite with the slurry-bed reactor for the ammoximation of cyclohexanone, the integration of silicalite-1 zeolite with the moving-bed reactor for the gas-phase rearrangement of cyclohex- anone oxime, and the integration of an amorphous nickel （Ni） catalyst with the magnetically stabilized bed reactor for the purification of caprolactam. The world＇s first industrial plant based on this green CPL produc- tion technology has been built and possesses a capacity of 200 kt·a-1. Compared with existing technologies, the plant investment is pronouncedly reduced, and the nitrogen （N） atom utilization is drastically improved. The waste emission is reduced significantly; for example, no ammonium sulfate byproduct is produced. As a result, the price difference between CPL and benzene drops. In 2015, the capacity of the green CPL produc- tion technology reached 3 ×10-6 t·a-1, making China the world＇s largest CPL producer, with a global market share exceeding 50%.

A reliable and consistent production technology for high volume compacted graphite iron castings

The demands for improved engine performance,fuel economy,durability,and lower emissions provide a continual challenge for engine designers.The use of Compacted Graphite Iron(CGI)has been established for successful high volume series production in the passenger vehicle,commercial vehicle and industrial power sectors over the last decade.The increased demand for CGI engine components provides new opportunities for the cast iron foundry industry to establish efficient and robust CGI volume production processes,in China and globally.The production window range for stable CGI is narrow and constantly moving.Therefore,any one step single addition of magnesium alloy and the inoculant cannot ensure a reliable and consistent production process for complicated CGI engine castings.The present paper introduces the SinterCast thermal analysis process control system that provides for the consistent production of CGI with low nodularity and reduced porosity,without risking the formation of flake graphite.The technology is currently being used in high volume Chinese foundry production.The Chinese foundry industry can develop complicated high demand CGI engine castings with the proper process control technology.

Study on In-vitro Production Technology of Embryos from Young Dorper Sheep

This study was conducted to investigate the in-vitro production technology of embryos from young Dorper sheep, so as to provide technical support for the utilization of ovarian follicles in young Dorper sheep. Tests were conducted from the induction of Dorper sheep of 4 to 8 weeks old using follicle stimulating hormone(FSH) and pregnant horse serum(PMSG), collection of oocytes, in-vitro oocyte maturation-fertilization-zygote cultivation and 2-4-cell-stage fertilized ovum transfer. The results showed that 585 oocytes were collected from eight Dorper sheep at the age of 4 and 8 weeks, with an average of 73.13 oocytes/sheep. 346 of the 2-4-cell-stage fertilized eggs were obtained, whose cleavage rate was 59.15%. 77 in-vitro fertilized eggs at 2-4-cell stage were transplanted into 17 recipient sheep, seven of which were pregnant and gave birth to 13 "test-tube sheep" with a conception rate of 41.18%. It is indicated that the hormone induction technique, in-vitro oocyte maturation-fertilization-zygote cultivation technique and 2-4-cell-stage fertilized ovum transfer technique used in this study can serve as effective techniques for the in-vitro production of embryos from Dorper sheep of 4-8 weeks old.

How Trade Liberalization of Intermediates Contributes to China's Technology Upgrade

Under a heterogeneous firm analysis framework,this paper creates a theoretical model to investigate how trade liberalization of intermediates influences the technology choice of firms based on the data of Chinese manufacturers during 2000-2006.According to our empirical result,after China's WTO entry,trade liberalization of intermediates significantly induced Chinese exporters to apply advanced technologies.In our further consideration of the differentiated productivity of firms,we found that such an effect is related to the initial productivity of firms and only significantly induces mediumproductivity firms to upgrade their technologies.In addition,the technology-promotion effect of trade liberalization of intermediates is the most significant for technology-intensive exporters and the least significant for labor-intensive exporters.
