Plant-Growth-Promoting Rhizobacteria Several microbes promote plant growth, and lots of microbial products that stimulate plant growth are marketed. during this review we restrict ourselves to bacteria that are derived from and exert this effect on the basis. Such bacteria are generally designated as PGPR (plant-growth-promoting rhizobacteria). The beneficial effects of those rhizobacteria on plant growth […]

Genetic diversity in Bradyrhizobium japonicum Jordan 1982 and a proposal for Bradyrhizobium elkanii sp.nov. Fourteen randomly selected clones from cosmid libraries of Bradyrhizobium were used as hybridization probes in Southern blot analysis. Seven of the probes used were from strain USDA 83, a gaggle II strain, and therefore the other seven were from strain I-110, […]

Aim: With the acquisition of the Kerma-Area-Product (KAP) meter, patient organ doses were estimated in order to analyze patient dose trends due to fluoroscopy exposure in two fluoroscopy centers. This gave the opportunity to report patient doses due to fluoroscopy exposure using the appropriate dosimetry procedure. Study Design: Cross-sectional study. Place and Duration of Study: […]

The aim of this work is to characterize banana tree residues and use it in pulping and combustion processes. The soda-anthraquinone pulping of the banana tree residues can be simulated by polynomial models, and then predict the pulp properties (yield, Kappa number, viscosity and brightness) as a function of operating variables (temperature 160 to 180°C, […]

The violation of energy conservation law is a death sentence for the General Relativity Theory (GRT). This paper investigates the correctness of the General Relativity Theory by studying the energy conservation during the relativistic free fall of a small test body in a uniform gravitational field. The paper compares predictions of energy conservation obtained from […]

In the framework of Fermi theory, nonstationary β -decay is considered. In order to simplify the calculations, the theory omits the accounting of antineutrino and neglects the presence of spin in the particles. The electron is called the mezon. Specifically, the non-stationary process of meson exchange between the neutron and the proton at the final […]

The emergence of satellite altimetry has allowed us to determine the ocean surface with a great precision; it also allows a large contribution for most applications and oceanographic activities. The geometric principle of space altimetry is to measure the range between the satellite and the sea surface. The objective of this paper is to estimate […]

This study is an investigation on neutronics parameters for Nigeria Research Reactor-1 (NIRR-1) core, a low power Miniature Neutron Source Reactors (MNSRs) using VENTURE-PC and SCALE 6.1 codes in the 19.75% enriched uranium dioxide (UO2)-Zircaloy-4 material. The number of active fuel pins used for this analysis is approximate 200 pins, which shows that the fuel […]

Solar variability affects Earth climate. It is proposed that this forcing primarily goes via the interaction of the Solar Wind with the Earth’s magnetosphere, rather than via changes in irradiance, which is generally assumed. The cyclic variations in Solar Wind emission generate corresponding changes in the Earth’s rate of rotation (LOD), as recorded by correlations […]

The power amplifier’s nonlinearity broadens the input signal’s bandwidth. This is known as spectral re-growth which is undesirable since it causes interference with adjacent channels. It also causes distortions within the signal bandwidth, which affects the bit error rate at the receiver. Most recent transmission schemes, such as wideband code division multiple access (WCDMA) or […]
