Long term survival will require you preserving food; it will require you building a permanent shelter. You will require a source of clean fresh water, you will have to provide any medical care required. Long term survival will require you making your clothing, as well as your shoes.

Concrete water storage and retention type vegetation base material and preparation method thereof

The invention discloses a concrete water storage and retention type vegetation base material and a preparation method thereof. According to the invention, continuously superposed round integrated holes are formed at the whole body of the vegetation base material; diameters of big holes are 2-15mm; small holes with the diameters of 0.5-3mm are bestrewed at the center and the periphery of each big hole; and holes are mutually communicated to ensure that internal pipelines and cumulative containers for water storage and water drainage for plant growth are formed. The concrete water storage and retention type vegetation base material disclosed by the invention is of a porous structure, longer in water retention time, suitable for long-term survival and growth of plants and capable of beautifying the cities, purifying the air and improving the environment and has the advantages that the water storage and retention rate is about 50% of self weight of the base material; strength and plasticity are endowed; living space conditions of the plants are satisfied; water and soil loss problem does not exist; the water storage and retention mechanism of the vegetation base material is also beneficial to increasing the humidity and purifying the environment; and the whole-body hole structure is adopted to ensure that the base material is capable of absorbing the sound and lowering the noise.

Novel aging mulberry rejuvenation and improvement method capable of allowing yield to be increased in the same year after half-year grafting time

ActiveCN103250574AProlong grafting timeAccelerate the transformation progressHorticultureRootstockCoriaria
The invention discloses a novel aging mulberry rejuvenation and improvement method capable of allowing the yield to be increased in the same year after the half-year grafting time, and belongs to the technical field of gardening mulberry cultivation. The method is characterized in that ear buds are inserted in the same direction; winter bud grafting and spring bud grafting are used simultaneously; and sawed pile multi-bud grafting is performed. An improved spring sawed pile bud grafting (ear bud inserting in the same direction and multi-bud grafting) is applied by the method, and a winter skin cutting and bud grafting method is successfully applied to winter and early spring sawed pile bud grafting by using a method of skiving a rough bark of a stock, so that the grafting time is prolonged to half a year during which ear strips are not required to be stored; the number of grafted ear buds of each mulberry is increased from 2-3 to 5-10 by adopting the multi-bud grafting, so that the yield can be increased by 50-200% in the same grafting year, and mulberry tree type cultivation can be accomplished on time; and a grafting body and a stock tree body can be healed tightly and firmly by adopting the ear bud inserting in the same direction, so that the long-term survival rate of the graft body is high. According to the method, the ear bud survival rate is not less than 97%; the mulberry survival rate is not less than 99%; and the method can be widely applied to renewal rejuvenation and variety improvement of aging trees of various mulberry fields, four-edge mulberries, daxing mulberries, coriaria sinia and arbor mulberries.

Tissue engineering bionic liver lobe structure based on 3D printing of living cells and preparation method thereof

ActiveCN110403731ARealize circular feedingAchieve gas exchangeAdditive manufacturing apparatus3D object support structuresFiberCulture fluid
The invention discloses a tissue engineering bionic liver lobe structure based on 3D printing of living cells and a preparation method thereof. Firstly, biological information of human body liver lobes is collected, and inputted into a computer for high biomimetic modeling; then, material separated printing and material-cell mixed printing output are performed with a hydrogel material and cells for constructing liver, bile duct epithelium, blood vessel endothelium, smooth muscle and fibroblast and the like required for the human liver lobes by a biological 3D printer, wherein a hollow part inblood vessels and bile ducts is printed by a casting agent; after all the hydrogel materials are solidified, the casting agent in the blood vessels and bile ducts are removed by means of enzymes or chelating reactions or temperature control or illumination and the like, and a vascular system and a bile duct system in the artificial bile duct-containing liver lobes are constructed. The circulationfeeding of the vascular system of the bionic liver lobes and gas exchange are achieved by connection of main blood vessels at two ends of the vascular system and a delivery pipe of a culture solution.The long-term survival and biological function of the bionic liver lobes in vitro and in vivo are achieved.

Method for constructing biomimetic vascular net in large-volume tissue engineering tissue organ

The invention discloses a method for constructing a biomimetic vascular net in a large-volume tissue engineering tissue organ. Firstly, biological information of a large-volume tissue of a human bodyis collected, and inputted into a computer for high biomimetic modeling; then, material separated printing and material-cell mixed printing output are performed with a hydrogel material and a varietyof amplified cells from the tissue by a high-precision biological 3D printer, wherein a hollow part in blood vessels is printed by a controllable degradable hydrogel; after all the hydrogel materialsare solidified, the controllable degradable hydrogel in the blood vessels are removed by means of specific enzymes or chelating reactions or temperature control or illumination and the like, and the vascular net in the large-volume artificial tissue is constructed. The circulation feeding of the vascular net and gas exchange in the large-volume artificial tissue are achieved by connection of mainblood vessels at two ends of the vascular net and a delivery pipe of a culture solution. The central feeding problem of the large-volume tissue is solved, so as to realize the long-term survival and biological function of the large-volume artificial tissue in vitro.

Vascularized tissue engineering bone and preparation method thereof

The invention relates to a vascularized tissue engineering bone and a preparation method thereof. The vascularized tissue engineering bone is composed of a support composed of poly-L-lysine (PLL) modified coralline hydroxyapatite (CHA) as well as a vascular endothelium dermatoblast patch and a bone formation cell patch which are sequentially wrapped at the inner layer of the support. According to the invention, an exogenous support obtained by virtue of the PLL modified CHA is beneficial to crawling ingrowth of blood vessels, and vascularization is realized finally, so that a precondition is provided for long term survival of cells in the tissue engineering bone, and organism immune rejection and inflammatory response are also reduced; adipose mesenchymal stem cells are selected for preparing a double cell patch, endothelial cells different in sources do not need to be added, cells are rich in resources and easy to separate and acquire, a trauma on a donor is minimal, ethical principles are not violated, and culture requirements are low. The vascularized tissue engineering bone provided by the invention is simple in preparation method and mild in preparation conditions, has good bone formation and vascularization properties, is consistent with in vivo application requirements, and has good application prospects as a novel vascularized tissue engineering bone.
