The environmental prospects of cultured meat in China

To deal with concerns in China about environmental degradation and a growth in population accompanied by increased consumption of livestock products, a meat alternative is required. This study compared the environmental impacts of producing different protein sources for nutrition, including crops, livestock products, and cultured meat. The results showed that cultured meat has the lowest land use per unit of protein and unit of human digestible energy. China＇s crops have the lowest energy use and greenhouse gas（GHG） emissions per unit of energy and protein. The energy use in cultured meat production is slightly higher than that of current pork production in China, whereas GHG emissions are lower. It is concluded that the overall impact of replacing livestock products with cultured meat would be beneficial for China＇s environment and would potentially improve food security because less land is needed to produce the same amount of protein and energy.

Cultured meat from muscle stem cells: A review of challenges and prospects

Growing muscle tissue in culture from animal stem cells to produce meat theoretically eliminates the need to sacrifice animals. So-called ＂cultured＂ or ＂synthetic＂ or ＂in vitro＂ meat could in theory be constructed with different characteristics and be produced faster and more efficiently than traditional meat. The technique to generate cultured muscle tissues from stem cells was described long ago, but has not yet been developed for the commercial production of cultured meat products. The technology is at an early stage and prerequisites of implementation include a reasonably high level of consumer acceptance, and the development of commercially-viable means of large scale production. Recent advancements in tissue culture techniques suggest that production may be economically feasible, provided it has physical properties in terms of colour, flavour, aroma, texture and palatability that are comparable to conventional meat. Although considerable progress has been made during recent years, important issues remain to be resolved, including the characterization of social and ethical constraints, the fine-tuning of culture conditions, and the development of culture media that are cost-effective and free of animal products. Consumer acceptance and confidence in in vitro produced cultured meat might be a significant impediment that hinders the marketing process.

Environmental Cultural Landscape Characteristics of Agricultural Vocational Colleges: A Case Study of Bioengineering Branch of Yangling Vocation and Technical College and Doucun Farm

Based on the overall planning of environmental cultural construction of Yangling Vocational & Technical College and the college–enterprise co-construction of Doucun Farm, this paper combined environmental cultural reformation inside and outside the college and reform of off-campus teaching experiment farm in view of outstanding agricultural characteristics of the bioengineering branch, with environmental health preservation as the fundamental goal and "health-preserving agriculture" as the link. In addition, four major characteristic landscape frameworks of "point, line, surface, and body" were established, and the effective construction approaches of health-preserving environmental cultural landscapes in vocational colleges were explored.

INFLUENCE OF MIXING DEVICE ON SERUM-FREE CULTIVATION OF INSECT CELLS IN SPINNER FLASKS

A culture system was developed and successfully employed for the serum-free cultivation of Tn-5B1-4 (Tn5 ) insect cells. With our adaptation procedure, it was possible to obtain cells fully adapted to serum-free media in stationary T-flasks and then enable these adapted cells to grow well in spinner flasks immediately. The spinner "ask with special stirring design proved tO provide favorable culture environment that made it desirable for use in the serum-free cultivation of Tn5 cells even at low seeding density.

Born of geographical environment, coloring for regional context： Concept and progress of geo-architecture

In today＇s world, where re-examination has been given to cultural globalization, the relationship between architectures and specific regions is one of many specific issues. At this time, the study of architecture from the perspective of geography has significant meaning for treasuring regional characteristics and protecting the essence of ethnic culture. The study of geo-architecture includes two aspects： the influence of geographical environment upon architecture and reflexively, architectural responses to geographical environment. In ＂Geo-Architecture and Landscape in China＇s Geographic and Historic Context Series＂（4 volumes）, published by Springer Nature in 2016, the contents of ＂geo-architecture＂ has been interpreted from various angles as form, function, semantics and symbol. This book is the first to be entitled ＂Geo-Architecture＂, which studies the relationship between geography and architecture from the perspective of geographical environment and historical context in China. The book＇s research reveals the influences of different geographical scales, such as zone（macro）, region（middle） and site（micro） scales, on architecture; it discusses dynamic and systematic thought, including such research elements as ＂Object-Subject-Time＂, and it reflects views on pattern and process of cultural landscape. Research on geo-architecture aims to help construct the security pattern of the cultural landscape for the new requirements of a new era, which is used to optimize spacial structure, stimulate heritage conservation and renewal, respect the geographical environment, pay attention to historical culture and sustain emotional memory.
