The invention relates to a seeding medium made of vinasse methane-sludge and a preparation method thereof, not only solving the problem of environment contamination caused by vinasse methane-sludge, but also effectively utilizing vinasse methane-sludge. The seeding medium comprises fresh sludge containing 90 percent of water after methane generated from vinasse in a methane tank, accessories, ferment strain I and ferment strain II, wherein the accessories comprise grass peat, vermiculite and perlite; the ferment strain I comprises saccharomycetes, lactobacillus, high-temperature actinomycetes and bacillus; and the ferment strain II comprises photosynthetic bacteria, lactobacillus, bacillus, saccharomycetes, actinomycetes and terrestrial cyanobacteria. The preparation method comprises the following steps of preparing fresh sludge, dehydrating, adding the ferment strain I for fermentation, adding the ferment strain II for secondary fermentation, air drying, adding accessories, crushing, screening and packing. The vinasse methane-sludge contains 40 to 50 percent of organic matter and 4.3 percent of available nitrogen (N), phosphorus (P) and kalium (K). The seeding medium made of vinasse methane-sludge has better hydrophilicity, and seeding can be carried out after loading the dry seeding medium and spraying water, thus saving both labor and time.

A method and a corresponding composition of matter for diagnosing or increasing the fertility of semen is described. The method involves measuring DNase activity in a semen sample, wherein greater DNase activity in the semen sample indicates increased fertility of the semen sample. Also described is a corresponding composition for storing and increasing the fertility of semen. The composition includes a diluent and an amount of exogenous DNase and-or fertility-associated antigen (FAA) disposed in the diluent. The amount of the exogenous DNase and/or FAA added to the diluent is effective to increase fertility of the semen stored in the composition.

Novel tricyclic cannabinoid compounds are presented. Some of these compounds exhibit fluorescence properties. The fluorescent cannabinoid compounds are typically endogenously fluorescent. Some of these compounds, when administered in a therapeutically effective amount to an individual or animal, result in a sufficiently high level of that compound in the individual or animal to cause a physiological response. The physiological response useful to treat a number of physiological conditions.

The invention discloses an ex-situ oil thermal-desorption method. According to the invention, soil to be repaired is preheated by using heat of bottom residues of a biomass circulating fluidized bed boiler through a heat pipe heat exchange manner, then, pollutants in the soil are desorbed by using heat of circulating ash of the biomass circulating fluidized bed boiler through a direct heat exchange manner, meanwhile, the fertility of repaired soil is improved by using active ingredients in the circulating ash, and gaseous pollutants generated by desorption are introduced into the boiler to be incinerated and decomposed. On the basis of waste heat of the bottom residues of the boiler, thermal desorption of soil is realized, meanwhile, the fertility of soil is improved by blending active ingredients, and volatile pollutants generated by desorption are conveyed into the boiler to be incinerated directly, so that secondary pollution is avoided.

The present invention relates to methods of increasing likelihood of conception, treatment of low fecundity and/or providing menstrual cycle control without suppressing ovulation in a female comprising administering an effective dose of at least one estrogen and at least one progestin within a treatment period of at least 21 days to 35 days or multiple periods thereof. Furthermore, the invention relates to the combination of at least one estrogen and at least one progestin for the preparation of a medicament to be used in the abovementioned indications. A pharmaceutical kit, according to the invention, comprises 21 to 35 dosage units or a multiple of 21 to 35 dosage units, wherein a first section comprises at most 21 dosage units of at least one estrogen; and a second section comprises from 2 to 34 dosage units of at least one estrogen and from 2 to 34 dosage units of at least one progestin or comprises from 2 to 34 dosage units of at least one estrogen and at least one progestin provided that in each dosage unit containing a progestin or a progestin and an estrogen the progestin is in a non-ovulation inhibiting amount; and and optionally a third section comprises at most 10 dosages of a pharmaceutically acceptable placebo or a blank.
