Working organs being used currently for subsurface tillage do not comply with agrotechnical requirements. In particular, the crumbling of soil layer is unequal across the width of cutting plane of working organ. The scientific hypothesis is that variable cutting angle along the length of blade improves the crumbling of soil layer. The mathematical model of interaction between the soil and a wedge is proposed. As the result, the theoretical dependencies of resistance force of soil to destruction and of thickness of shear layer on the setting angle of tillage tool are obtained. A set of dihedral

A-hoe blades consisting of a share and a frog are used as working organs of cultivators. Main characteristics of share are the expansion angle of blades and the crumbling angle. For falling away of cut weed, the expansion angle should not exceed 70 degrees. The higher crumbling angle provides more intensive effect on the soil. There are also negative effects in working process: soil displacement aside, formation of grooves, removal of moist soil to the daylight surface.

Abstract Layer-by-layer loosening of soil contributes to an increase in energy consumption for its cultivation. Thus, in order to reduce traction resistance, a blade with a variable crumbling angle has been developed. In the blade stand area, it is proposed to increase crumbling angle of the chisel plow by analogy with working bodies of the chisel plow to 300, and the blade wing should be made in the form of a flat-cutting blade with a small crumbling angle. To substantiate paw profile in the strut zone, a static equation of action of forces has been drawn up depending on curve shape of the fr

Due to ongoing climate change, the demand for water in agriculture is increasing annually, while water scarcity becomes more pronounced. Therefore, every drop of water must be efficiently conserved. Mineral nutrients are applied to improve the reclamation status of saline and gypsiferous soils before leaching them. However, these nutrients often do not reach the root layer of plants. To address this issue, we conducted a study to determine the optimal opening angle of the winged blades in the fertilizer system of a chisel-cultivator.

The need to develop specialized machines and equipment for laboratory and field research on potato breeding is due to the fact that the methodology of breeding processes and the first stages of seed production involves comparing many plants of different origins and selecting the best for further work up to the creation of a new variety or transfer of seeds for propagation in production conditions. The large variability of machines for unloading vegetables and potatoes does not adequately prevent damage to vegetable and potato products, which is due to the imperfect design of such machines, inc

The article presents the results of field studies to determine the quality and energy indicators of a modernized cultivator for strip tillage for industrial crops. An experimental setup with load cells with a nominal value of 30000 N is designed to measure the tractive resistance of the cultivator in the field. The result of the study is to establish the relationship between the cultivator traction resistance on the speed movement at various angles of spherical disks attack and the degree of crumbling on the structural and technological parameters of the cultivator.

Early modern connections between the Pacific shores of the Spanish Empire have been assessed in previous studies and yet, studies on the subsequent developments during the late eighteenth and early nineteenth centuries are scant. This particularly applies to the consequences of the commercial developments at the end of the Manila Galleon and the collapse of the Spanish Empire in America. Through the analysis of the professional networks of Francisco Xavier de Ezpeleta, and Juan Nepomuceno Machado, which stretched from Asia to Mexico at the time, this paper proposes some preliminary conclusions

Surat, the waning port city of the departed Great Mughals, was rocked by riots on 6 August 1795. The lower orders of the Muslim population fell upon the shops and houses of the Bania residents of the city, looting grain, demolishing the images of their gods and tearing up their account books. This was the response of a collapsing social order to the thrust of a highly adaptive banking and trading group which had adroitly allied itself to the rising English power on the West Coast of India.

The results of theoretical studies of a disk cultivator are presented, the working units of which consist of two flat discs, inclined to each other in the horizontal and vertical planes. The distance between the upper leading edges of the discs is greater than between the lower rear edges. When the discs move in the soil, the layer is jammed between them, breaks off from the bottom of the furrow, rises slightly upwards and is laid back into the furrow in the loosened state. The main constructive and adjusting parameters of the working unit are the inclination angles of discs γ, the distance be

In the traditional technology of cultivation and harvesting of grain crops, pre-sowing soil cultivation is one of the main agricultural operations. It is performed by various cultivators and combined units. In general, they reliably and efficiently perform the technological process, however, when processing heavy soils, the degree of crumbling of the soil prepared for sowing does not meet agrotechnical requirements.

Оснащение предохранительными пружинами предотвращает его от деформации и поломки при работе на каменистых почвах. Перспективность заключается в том, что вспашка осуществляется на глубину 10…15 см, а нижний малоплодородный слой разрыхляется без выворачивания его на поверхность почвы.

Rationale. Improvement of the annular working bodies by dividing the solid cutting blade into separate parts (cutting knives) and turning them at an angle to the axis of rotation provides conditions for stable sliding of the soil over the working surface. The lack of knowledge of the process of furrow formation by these working bodies prevents the choice of their parameters that ensure the evenness of the bottom of the furrow in accordance with agrotechnical requirements.

 I. The Fidelity Reflex When Robert Stam entitles one of his recent efforts to theorise adaptation “Beyond Fidelity,” he could be speaking for a wide range of critics (54). Indeed, as the editor of two major adaptation anthologies, he is speaking for them. Stam’s principal objection is the covert moralising of fidelity discourse: “The conventional language of adaptation criticism has often been profoundly moralistic, rich in terms that imply that the cinema has somehow done a disservice to literature. … The standard rhetoric has often deployed an elegiac discourse of loss,

 Biology teaches us that organisms adapt—or don’t; sociology claims that people adapt—or don’t. We know that ideas can adapt; sometimes even institutions can adapt. Or not. Various papers in this issue attest in exciting ways to precisely such adaptations and maladaptations. (See, for example, the articles in this issue by Lelia Green, Leesa Bonniface, and Tami McMahon, by Lexey A. Bartlett, and by Debra Ferreday.) Adaptation is a part of nature and culture, but it’s the latter alone that interests me here. (However, see the article by Hutcheon and Bortolotti for a discussi
