Solar greenhouse use advice for new building materials

Throughout the year with the weakest light from December 23-25, 2002 and the lowest temperature from January 15-17, 2003, seven consecutive observations of indoor and outdoor air temperatures, ground temperature, and light intensity for eight types of building materials Analysis, concluded:

The first is that the 15-20 cm thick polyphenylene plate with the composite inorganic material wall can play the thermal insulation performance of the brick wall more than 50 cm, but its thermal storage performance is poor. The pure solar greenhouse should be combined with the inner wall of the greenhouse to add 12 The ~24 centimeter brick wall can not only play a good role in heat preservation and heat storage, but also save land. The construction cost is equal to that of a 50 cm thick brick wall, which can be widely promoted and used;

The second is that complex inorganic material skeletons (especially column-free structures) encounter large snow conditions during observation, and all three types of composite inorganic material structural skeletons have damages. Their safety and durability are not guaranteed and they should not be promoted in suburban areas. ;

The third is that the heat insulation performance of the roller shutter is better than that of the straw curtain or puddle. The cost should be further studied to improve the insulation capacity. The fourth is the multifunctional agricultural film with the functions of drip, anti-aging and heat preservation. Greenhouse observations show little difference in light transmission and can continue to be applied.

PMU is used to produce estrogen and hormone-replacement drugs such as Premarin, PremPro and PremPhase and DUAVEE, a "PremPro-Lite" which contains Premarin. PMU drugs are made by keeping mares constantly pregnant and collecting their estrogen-rich urine. The horses should be in good healthy, age from 4-15 years old, the color should be dark. the horses should be check-up and disinfected during the transportation. The blood taking should be called off immediately when infectious disease is found, any medicine of Penicillin and streptomycin is forbidden to use.
