This study analyzed the compound growth rate (CGR) and contributions of yield area to cassava production output in Nigeria. In these analyses, factored into consideration, each periods, triennium beginning (TB) ending (TE). During period, TB 1970 – TE 1995, oscillated between 10.7t/ha (TE 1972) 10.6 t/ha (TB 1996). At this CGR for (0.7%), (10.8%) (11.5%) were positive. The decomposition analysi...

In recent years, computational fluid dynamics has been increasingly used in the development of various types rotating machines. case water turbines and pumps, a large number researches have published recently, related to use different numerical methods for prediction efficiency, cavitation characteristics dynamic phenomena. For basic analysis an accurate result near optimal operating regime is ...

Effectiveness of ventral surgical approach in correction atlanto-axial instability dogs toy breeds was analyzed the research. 135 clinical cases correction, general concept access and implant placement, which minimize risks iatrogenic complications, were studied. Ventral stabilization carried out by forming an arthrodesis between atlas epistropheus inserting screws or spokes through articular s...

The flow instability of a double-blade centrifugal pump is more serious due to its special design feature with two blades and large passages. dynamic instabilities pressure pulsations can affect the performance operating lifetime. In present study, numerical investigation unsteady time variation within complete was carried out. domain frequency were extracted at 16 monitoring locations covering...

This article reflects on the vulnerability of new digital platform workers regarding their social rights, a highly controversial issue at doctrinal and jurisprudential levels. Firstly, we analyse greater job instability lack protection experienced by in this type platforms, labour legal framework that derives from these business models. In sense, current doctrine can be grouped into two positio...

In this paper, we analyzed the long-run relationship between political instability and shadow economy in Uganda using autoregressive distributed lag bounds testing approach to cointegration. We found a negative statistically significant economy, both short-run. This implies that an improvement processes creates stability incumbent regime significantly reduces consistent with view institutions p...

In this article, it is shown that under certain conditions, the spectral difference (SD) method is independent of the position of the solution points. This greatly simplifies the design of such schemes, and it also offers the possibility of a significant increase in the efficiency of the method. Furthermore, an accuracy and stability study, based on wave propagation analysis, is presented for s...

Pipes for deep-water applications possess a diameter-to-thickness ratio in a region where failure is dominated by both instability and plastic collapse. This implies that prior to failure the compressive yield strength of the material must be exceeded, followed by ovalisation and further local yielding. This paper presents an investigation into the mechanics of this specific problem and develop...

We investigate correlations between the long wavelength fluctuations and the small scale power in the Lyman alpha forest. We show that such correlations can be used to discriminate between fluctuations induced by large scale structure and those produced by non-gravitational processes such as fluctuations in the continuum of the quasar. The correlations observed in Q1422+231 are in agreement wit...
