Disclosed are devices for urine voiding postponement, and methods for treating conditions such as central diabetes insipidus, enuresis, nocturia, urinary frequency or incontinence. The devices deliver a desmopressin flux through the skin of a patient in a low dose amount just necessary to achieve a desired anti-diuretic effect without undesirable side effects such as hyponatremia. The devices are designed to permit a state of normal urinary production to return quickly after the desmopressin flux is terminated.

A controlled release dosage form for sertraline has a core comprising a sertraline-containing composition and a water-swellable composition wherein the water-swellable composition is in a separate region within the core. A coating around the core is water-permeable, water-insoluble, and has at least one delivery port therethrough. In one embodiment, the dosage form releases sertraline to the use environment at an average rate of 6 to 10 wt % per hour from the second to the twenth hour after introduction to a use environment and less than about 25 wt % for the first two hours and at least 70 wt % by the twelfth hour, where the percentages correspond to the mass of drug released from the tablet divided by the total mass of drug originally present in the tablet. In another embodiment, the dosage form releases less than about 25 wt % of sertraline to the use environment by the second hour after introduction of the dosage form to the use environment, and delivers at least 25 wt % from the eighth to the twenty-fourth hour.

A light-emitting diode structure with transparent window covering layer of multiple films includes one (or several) first transparent covering layer(s) and one (or several) second covering layer(s), which are formed on the outside of the light-emitting diode chip. The light-emitting diode chip can emit light in more than two wavelengths to increase the transmission of the different wavelengths and the taking out efficiency of the light-emitting diode. The first transparent covering layer(s) and the second covering layer(s) are deposited each on the other on the outside of the light-emitting diode chip. The surface of the light-emitting diode with the covering layers is smooth. The contacting parts of the first transparent covering layer(s) and the second covering layer(s) are connected by a strong adhesive force and the contacting parts of the covering layer and light-emitting diode chip also are connected by a strong adhesive force.

A method for recovering metal values from refractory sulfide ores is provided. The method includes the steps of separating clays and fines from crushed refractory sulfide ore, forming a heap from the refractory sulfide ore, producing a concentrate of refractory sulfide minerals from the separated fines and adding the concentrate to the heap, bioleaching the heap to thereby oxidize iron sulfides contained therein, and hydrometallurgically treating the bioleached ore to recover metal values contained therein.

The invention relates to the technical field of lavender planting, in particular to a cultivation and management method of seedlings special for a lavender flower sea. The cultivation and management method of the seedlings special for the lavender flower sea comprises the following steps: (1) preparing land; (2) selecting and trimming cuttings; (3) laying mulching films; (4) conducting cutting andmanagement before rooting of the cuttings; and (5) conducting seedling management. The cultivation and management method of the seedlings special for the lavender flower sea is characterized in thatin the step (5), when the flower seedlings grow to 12-15 cm in height, primary trimming is conducted, trimming and irrigation work is conducted every 20-25 days to control the height of the flower seedlings to be 8-10 cm, 4-5 months after repeated operation is conducted, trimming is stopped, fertilization and irrigation work is conducted every 20-25 days instead, and operation is repeated for 1.5-2 months. According to the cultivation and management method of the seedlings special for the lavender flower sea, topping is conducted on the cuttings, branching points and the height are unified, and many branches are grown during first growth; many branches are grown during emergence, and the number of flowers is large after planting is conducted; and the cultivated lavender seedlings are evenin size, and a landscape effect is good after planting is conducted.
