Abstract Oil production is currently impossible without drilling wells, so millions of tons waste contaminated with oil, chlorides, and heavy metals are generated every year in Russia alone. This article presents the results a comparative life cycle assessment water-based drill cuttings management technologies applied Russia, including disposal, solidification, reinjection. Life was performed u...

The article highlights the problems of ensuring continuous unloading energy willow cuttings from slotted bunkers. During free discharge rod-like bodies, such phenomena as crypt formations, distortions, pinching occur, which stop under action gravity. Finding parameters, system will work evenly and without stops, make it possible to automate many processes related working with material, in parti...

This thesis describes the methods used to analyse and model the cutting of pig carcasses into the products: back, belly, spine and ribs. Automatic pre-processing methods to segment out the individual products from raw DICOM images are developed. A bit resolution reduction method is presented for producing images that are readable for other software. Image registration method are studied and use...

This article highlights the efficacy of plant growth regulators and nutrient solutions on root development and survival of ascending purple milkvetch (APMV) cuttings. Three auxin-like growth regulators and Hoagland solutions were used as root inducing agents. The cuttings were planted in sand medium that allowed evaluation of rooting effectiveness. The study showed that up to 100% establishment...

(1) Global movement of propagative plant material is a major pathway for introduction of Bemisia tabaci (Hemiptera: Aleyrodidae) into poinsettia greenhouses. Starting a poinsettia crop with high pest numbers disrupts otherwise successful biological control programs and widespread resistance of B. tabaci against pesticides is limiting growers' options to control this pest; (2) This study investi...

for vegetative propagation of nemaguard, st julien a, tetra and gf677 rootstocks via cutting, two separate experiments were carried out in a factorial based on completely randomized design. semi hardwood cuttings were taken in late august and then treated with concentrations of zero, 1500, 2000, 2500 and 3000 mg/l iba. cuttings were cultured in perlite medium and in a greenhouse with mist syste...

Abstract Ninebark ( Physocarpus opulifolius ) is an attractive ornamental shrub with poor rooting characteristics in some cultivars, which a limiting factor commercial production This study was designed to optimize conditions of ninebark cuttings and observe the effect exogenous auxin IBA on morpho-anatomical biochemical changes associated rhizogenesis vitro conditions. Both auxins under study:...

Type and effect systems provide a safe and effective means of programming high-performance parallel computers with a high-level language that integrates both functional and imperative paradigms. Just as types describe what expressions compute, effects describe how expressions compute. Types and effects are associated with regions that describe where dynamically-allocated data structures reside ...

inserts the cuttings into plug trays. While the system has been shown to process effectively many plants automatically, the robot is not equipped to handle successfully the wide variety of cuttings that a trained worker handles with aplomb. A key challenge in greenhouse automation will be to develop productive systems that can perform in a reliable and cost-effective way with highly variable Au...

We have seen the use of partition trees for range searching earlier. In this lecture an efficient partition scheme which achieves the optimal query time within polylog factors is described. See [4] and [5] for more details. There are several new ideas on which this scheme relies. The existence of “good” cuttings are central to the algorithm. In the next section some of the definitions and resul...
