Abstract: FIELD: agricultural engineering, in particular, sewage water irrigation equipment. 
     SUBSTANCE: irrigation system has supply pipeline. Sewage water is delivered through supply pipeline into mechanical purification construction and further into double-sectioned accumulating tank to be diluted with pure water in the ratio of 1:3. Diluted sewage water is supplied via distribution channel into irrigator and further via stationary irrigation pipes into irrigation furrows for flooding thereof. Stationary irrigation pipes are positioned on irrigator dam in spaced relation with respect to one another, said space ranging from 0.6 m to 0.9 m, depending on slope of irrigation level. For irrigation of continuous seeding farm crops on irrigation level with gradient of 0.004-0.007, width of flow-through irrigation furrow bottom is from 0.13 m to 0.15 m, width of flow-through furrow top part is from 0.23 m to 0.25 m, depth is from 0.10 m to 0.12 m, and width of spacing is 0.60 m. In irrigation zone with gradient i ≤ 0.004, flow-through irrigation furrow has bottom width of from 0.23 m to 0.25 m and top width of from 0.33 m to 0.35 m, depth of from 0.09 m to 0.11 m and width of spacing of 0.90 m. It allows irrigation stream horizon to be above furrow ridge by 0.02 m to 0.03 m. Such system allows irrigation norm to be reduced by 2-3 times for irrigation of continuous drilling crops on irrigation zones with gradient below 0.007. As a result, sewage water is localized only within active layer of ground. 
     EFFECT: uniform wetting of crop root system of narrow row crops, especially at the initial germination stage, reduced consumption of deficit irrigation water and improved ecological safety for environment.

Abstract: FIELD: industrial organic synthesis. 
     SUBSTANCE: saturated or β,γ-unsaturated carboxylic acids are obtained by carboxylation of compounds having ethylenic or acetylenic bond conjugated with another unsaturated bond or electronodonor group via their reaction with carbon monoxide and water in presence of palladium-based catalyst. On completion of carboxylation reaction, carbon monoxide is removed from reaction mixture by treating the latter with gas to attain CO concentration below 600 ml in 1 L solution. Once carboxylation is ended, reaction mixture is treated with hydrogen to reduced Pd(II) into metallic Pd, which separated from reaction mixture as precipitate. Advantageously, following compounds are carboxylated: diolefins, allyl alcohols, allyl ethers or esters with conjugated unsaturated bond. In particular, reaction of butadiene results in production of pentene acids. 
     EFFECT: prolonged catalyst lifetime due to enabled regeneration and reuse thereof.
