Preparation method for artificial corneas

The invention discloses a preparation method for artificial corneas. The preparation method comprises the following steps of (1) collecting age-appropriate pig eyeballs; (2) scraping corneal epithelial cells and corneal endothelial cells of the pig eyeballs, reserving bowman layers, preparing lamellar corneas by using a lamellar blade, and drilling size-specific corneal slices; (3) putting the corneal slices obtained in step (2) in liquid nitrogen for 8-35 minutes, slowly rewarming the corneal slices to room temperature under normal temperature and normal pressure after the corneal slices are taken out, repeating the operation for 4-12 times; (4) putting the corneal slices which are subjected to freezing-thawing treatment in step (3) in normal saline for carrying out ultrasonic cleaning, wherein the ultrasonic working frequency is 20-250 kHz, and the ultrasonic time is 15-65 minutes; (5) putting the corneal slices which are subjected to ultrasonic treatment in a buffer system, carrying out enzymolysis on DNA (Deoxyribose Nucleic Acid) of corneal stromal cells by using endonuclease, and obtaining the artificial corneas. According to the artificial corneas prepared by the preparation method disclosed by the invention, gaps between natural collagen fibers of the artificial corneas are beneficial for inducing the growth of the corneal cells and the growth of nerve fibers of an acceptor and promoting the repairing and the reconstructing of corneas of a donor.

Cognitive educational tool for effectuating learning

The following concept is to be utilized in the acquisition of information by combining various learning styles. Key areas addressed are the increment of student participation, increased levels of student honesty, and higher rates of student responsivity. The tool encourages the development of student-teacher rapport levels and thus promotes the ability to acquire and retain functional techniques and information. The concept addresses real life situations by creating functional problem solving strategies to be used at specific junctures in both the scenarios and everyday life. The tool is preventative in nature, and is also culturally, cognitively, age appropriate, gender and scenario flexible. The adaptability highlights the vast spectrum of issues the concept can resolve. Overall the process is designed to increase participants' level of competency when encountering situations, which impact their pro social development and / or success in real life situations. In doing so the likelihood of engaging in detrimental or negative behaviors is significantly reduced. The program focuses on enhancing social skills, responsibility, self-control, pro social cognition, and moral reasoning. All of the aforementioned skills are nurtured and developed through the alternative learning style used to engage the client, through the therapeutic process.

System for training psychological education teaching in virtual reality

InactiveCN109615956ASolve the problem of the differentiation of educational resourcesData processing applicationsElectrical appliancesCrowdsHuman–robot interaction
The invention provides a system for training psychological education teaching in virtual reality (VR). The system comprises head-mounted VR equipment, a simulated teaching resource cloud platform anda personal database. The system uses teaching reality of a famous teacher as a key link, generates a VR resource of teaching of the famous teacher by a three-dimensional digital technology, and storesin a sever for establishing a simulated teaching resource cloud platform; a user establishes a personal learning database according to a desired learning resource downloaded from a cloud platform according to own needs, and acquires an immersive learning experience by the head-mounted VR equipment; meanwhile, personal information, learning content and learning progress data are uploaded to the cloud platform; a discussion community is established together with other users to obtain online guidance of the famous teacher. The system supplements and perfects the conventional education system, sothat students and age-appropriate people from different regions can learn intuitively and vividly in a three-dimensional scene in a way of human-computer interaction, and can obtain high-quality education without crossing regions, thereby effectively solving a problem that educational resources between regions are different.

Method for hydroponics seedling raising of arrowheads

The invention discloses a method for hydroponics seedling raising of arrowheads, including the following steps: (1) top bud disinfection: the top bud of an arrowhead is cut and the top bud is immersedin disinfectant for 30 to 45 minutes; (2) hydroponics seedling raising: the top bud after step (1) treatment is evenly distributed in a slag water culture pond; a water layer is kept at 2 to 5 centimeters; after 5 to 10 days of growth, nutrient solution is added and the water layer is kept at 8 to 15 centimeters; transplants can be carried out after 25 to 30 days. In the method for the hydroponics seedling raising of the arrowheads, hydraulics arrowhead seedlings can save labor, facilitate management and break through seasonal restrictions to quickly provide age-appropriate, robust and non-toxic seedlings and shorten time for vegetable farmers to engage in the production of the arrowheads. The hydraulics seedlings of the arrowheads have more vigorous growth and developed roots. Diseases such as powdery mildew have been significantly alleviated. A root system is isolated from soils, thereby being capable of avoiding various soil-borne diseases and soil disinfection. The hydraulics seedlings of the arrowheads do not need to replace the nutrient solution halfway. The robustness of the seedlings is higher than the robustness of the seedlings in common seedling raising methods. The developed root system has strong adaptability to hydroponics. The tillering speed is fast. The grow-seedling stage is short with 25 to 30 days.
