Các mô hình nhà nổi làm bằng tre chống đại hồng thủy và bảo tồn rái cá Trong những năm cố gắng bảo tồn rái cá trên sông Thị Vải bị người dân cố tình sát hại và quấy rối việc chăm sóc rái cá. Tiun quyết định làm 1 căn nhà nổi trên sông tránh xa dân cư để bảo vệ rái cá tốt hơn. Dự kiến căn nhà nổi sẽ được làm bằng tre để giúp rái cá sinh sản và phát triển trên sông an toàn và bền vững. Tiun đã tìm hiểu mô hình nhà nổi Floating Bamboo House của H&P Architects, thiết kế để chịu được mực nước biển dâng cao, nhằm mục đích cung cấp cho người dân địa phương sống ở và xung quanh Đồng bằng sông Cửu Long tại Việt Nam ngôi nhà ở chống chịu được biến đổi khí hậu. Cám ơn nhà sáng lập Đoàn Thanh Hà đã cho Tiun ý tưởng những mẫu nhà nổi bằng tre và thiết kế bên trong để tạo ra căn nhà phục vụ bảo tồn rái cá trên sông Thị Vải. Thiết kế nội thất bên trong nhà nổi bằng tre Nhà nổi bằng tre là nhà ba gian, với mặt bằng tầng trệt hình vuông có kích thước 6mx6m và tầng trệt ở mái hiên. Hình dáng bên ngo...
What are merman tails and fins?
Merman tails and fins have become a popular aquatic toy mainly targeted at our children. Both feet go into a single fin that looks like a ‘merman/mermaid’ tail which allows people to swim using a dolphin-like movement. There are two types: One that is fully enclosed from the waist down. The other is a single fin for the feet only without the extended ‘tail’.
What are monofins?
Monofins are similar, in that both feet fit into one fin. However, these fins are bigger and made of fiberglass or carbon with rubber foot pieces. These types of monofins are usually used for competition, as Fin Swimming is a competitive sport at a world championship level. People also swim with monofins for fitness purposes. It is best to use monofins under a qualified coach.
What dangers do merman tails and fins pose?
These products are considered to be aquatic toys. Like all aquatic toys, safety precautions need to be taken whilst playing in and around the water. Swimming with merman tails and fins should only occur under active adult supervision at all times. Be aware that some tails and fins are fully enclosed from the waist down, effectively binding the legs together. Recent research has found that merman tails and fins that bind a child’s legs together reduce their swimming ability by up to 70%, and make it difficult for them to balance and support themselves whilst standing or swimming in a pool - this may increase their risk of drowning. Consider choosing fins that do not bind the legs together and that easily release the feet.
Who can swim with merman tails and fins?
The wearer should be an experienced and competent swimmer. When children first use merman tails and fins, they should practice in the water with an adult. While wearing the tail or fin, it is important they can competently float on their front and back and maneuver their body into an upright position. They should be able to independently release their feet from the fin and be able to move to a safe position e.g. to the side of the pool, to the ladder, or to shallow water. It may take a few times before they feel fully capable and confident to swim with the tail or fin, especially when first attempting dolphin kicking. Movements that disorientate like somersaults, handstands, and going under or through submerged objects shouldn’t be attempted. Merman tails are not recommended for young swimmers (under the age of 7) or non-swimmers.
What is the best environment for using merman tails and monofins?
These products should only be used in controlled environments such as a swimming pool under active adult supervision. It is not recommended to use merman tails and fins in open water environments as these are unpredictable with currents, swells, and rips which increase risk when swimming.
