Access method for periodic contention-free sessions

An access method for periodic contention-free sessions (PCFS) reduces interference between overlapping first and second wireless LAN cells contending for the same medium. Each cell includes a respective plurality of member stations and an access point (AP) station. The access method for periodic contention-free sessions (PCFS) includes a fixed cycle time that reduces conflicts with PCFS from other cells. The PCFS from several cells are repeated in cycles of cycle period (CP), which is the contention-free period (CFP) of an access point times a factor that is a function of the number of overlapping cells. Periodic contention-free sessions (PCFSs) are generated, one from each overlapping cell. PCFS transmission attempts occur at the fixed specified time spacing following the start of the previous cycle. Each active AP sets a timer at CP and a PCFS is initiated when the timer expires. The timer is then reset to CP and this starts a new cycle. Contention transmissions are attempted by stations based on their assigned priority. If a channel is busy at the designated start time for transmitting a PCFS, the PCFS is shortened by the time lost. Interleaving PCFSs and CFSs reduces conflicts with CFSs from other cells. To lessen the contention between APs of different cells, each station's Network Allocation Vector (NAV) and Inter-BSS Network Allocation Vector (IBNAV) is updated by an increased value of the next CFS length, the increment being the inter-BSS contention period (IBCP). APs will attempt to access the channel during the IBCP only for transmitting a PCFS, while they will wait for the NAV and IBNAV expirations before attempting to transmit a CFS. Interleaving PCFSs and CFSs also enables maintaining quality of service (QoS).

Anion anti-microbial mildew-proof floor

The invention discloses an anion anti-microbial mildew-proof floor. The mildew-proof floor is composed of a damp-proof layer, a TCM (Traditional Chinese Medicine) board layer, an anion adhesive layer and a wear-resistant layer, wherein the damp-proof layer, the TCM board layer, the anion adhesive layer and the wear-resistant layer are sequentially arranged from down to up, and the upper and lower surfaces of the TCM board layer are respectively glued with the damp-proof layer and the wear-resistant layer through the anion adhesive layer; the anion adhesive layer consists of a soy protein adhesive and anion natural mineral substance powder, wherein the mass ratio of the soy protein adhesive to the anion natural mineral substance powder is 4:1, the anion natural mineral substance powder is a mixture of tourmaline, lanthanide rare earth compound salt and titanium dioxide in accordance with the weight ratio of 4:3:3, therefore anions can be continuously released to remove formaldehyde, other hazardous substances and indoor peculiar smell, and realize bacteria resistance and bacteriostasis and purify indoor air, so health efficacy is achieved; furthermore, Chinese herbal medicinal ingredients contained in the anion anti-microbial mildew-proof floor can play a role in mosquito repellent, bacteria resistance, bacteriostasis and multiple functions, therefore the anti-microbial mildew-proof floor has an extensive application prospect.

The invention relates to a preparation method of preserved rice noodles. The preparation method includes the steps of rice machining and sand filtration, smashing, humidity adjustment, extrusion for gelatinization, extrusion for emerging of silk noodles, cutting off, checking and packaging. The preparation method is characterized by taking the rice noodles before extrusion for emerging of silk noodle and drying as materials, wherein the water content of the rice noodles at the moment is 25wt%-30wt% and the temperature is 40-60 DEG C; cutting the rice noodles to 17-19cm; soaking the rice noodles for 60-100min in Didazuril bactericide solution with concentration of 50%-60% and temperature of 35-45 DEG C, wherein the ratio of material to liquid is 1wt%:5wt%; conducting vacuum packaging, wherein the vacuum degree is 0.09MPa-0.092Mpa; thermally sterilizing the rice noodles for 0.5h-1h in a water bath maintained at the temperature of 90-95 DEG C; cooling packaging bags with circulating cold water so as to fast reduce the temperature in the center of the packaged material to 30-35 5 DEG C; blowing the water at the outer surfaces of the packaging bags to dry; checking whether the packaging bags bulge and break and conducing metal detection; putting the rice noodles together with auxiliary materials such as matched sauce bags in a packaging box; and sealing the packaging box, thus obtaining a finished product. For the preserved rice noodles produced according to the preparation method, the water content is higher than 60% and the quality guarantee period is longer than 6 months; the infusing and dispersing performance is good; caking does not happen and undesirable odor does not emerge; the dissolving starch rate of the rice noodles is low; after culture for 1 month at the temperature of 37 DEG C, the rice noodles achieve 1426g of hardness, 26.14gs of crisp performance, 512 of viscosity, 0.513s of viscoelasticity.

Method for breeding blue-lower-leg spotted-brown-feather laying hens with high egg yields

The invention discloses a method for breeding blue-lower-leg spotted-brown-feather laying hens with high egg yields. The method comprises the following steps of: artificially inseminating and mating a large quantity of Huainan spotted-brown cocks serving as male parents and Loman laying hens serving as female parents, collecting hatching eggs and hatching an F1 generation; identifying cocks and hens according to the colors of feathers and lower legs, eliminating white-feather yellow-lower-leg chicken which are cocks, reserving spotted-brown-feather blue-lower-leg chicken which are hens for serving as breeding hens, and performing back crossing by taking Huainan spotted-brown cocks as male parents to produce an F2 spotted-brown-feather generation; crossly mating and fixing the F2 generation and performing family breeding to produce an F3 generation; and performing gradual pure breeding on the F3 generation and later generations and obtaining the blue-lower-leg spotted-brown-feather laying hens with high egg yields according to egg yield, protein, lower leg color, feather color and bodily form, wherein the feathers are spotted-brown feathers; and the bodily form refers to delicate and pretty bodily form, blue lower leg and blue beak. According to the method, an appropriate high-egg-yield gene is introduced into a local chicken breed, and the proteins and macroscopic features of the local chicken breed are kept simultaneously.
