Year: 2015

We numerically study different forms of nanoscale gaseous domains on a model for rough surfaces. Our calculations based on the constrained lattice density functional theory show that the inter-connectivity of pores surrounded by neighboring nanoposts, which model the surface roughness, leads to the formation of stable microscopic Cassie states. We investigate the dependence of the stability of the micro-Cassie states on substrate roughness, fluid-solid interaction, and chemical potential and then address the differences between the origin of the micro-Cassie states and that of surface nanobubbles within similar models. Finally, we show that the micro-Cassie states share some features with experimentally observed micropancakes at solid-water interfaces.

description: Near-field optical micromanipulation permits new possibilities for controlled motion of trapped objects. In this work, we report an original geometry for optically deflecting and sorting micro-objects employing a total internal reflection microscope system. A small beam of laser light is delivered off-axis through a total internal reflection objective which creates an elongated evanescent illumination of light at a glass/water interface. Asymmetrical gradient and scattering forces from this light field are seen to deflect and sort polystyrene microparticles within a fluid flow. The speed of the deflected objects is dependent upon their intrinsic properties. We present a finite element method to calculate the optical forces for the evanescent waves. The numerical simulations are in good qualitative agreement with the experimental observations and elucidate features of the particle trajectory. In the size range of 1 μm to 5 μm in diameter, polystyrene spheres were found to be guided on average 2.9 ± 0.7 faster than silica spheres. The velocity increased by 3.0 ± 0.5 μms-1 per μm increase in diameter for polystyrene spheres and 0.7 ± 0.2 μms-1 per μm for silica. We employ this size dependence for performing passive optical sorting within a microfluidic chip and is demonstrated in the accompanying video.

description: Livestock plays a significant role to enhance Indian economy through production of milk, meat, draught power and wool. The contribution of livestock sector in GDP is 4.11% and 25.6% of total agriculture GDP. To obtain maximum gain from livestock, it is necessary to rear their young ones into healthy and productive animals. Bovine respiratory diseases (BRD) are important cause of mortality and morbidity in young pre weaned calves and heifer. It is a complex disease caused by multiple pathogens concurrent with exposure to various stressors such as weaning, transportation, castration and ambient temperature. These conditions can cause immunosuppression and promote respiratory tract or lung infection. Wide range of pathogens are involved in the development of calves pneumonia include bacteria, viruses, parasites and fungi. Calves’ pneumonia and shipping fever are important components of bovine respiratory disease which affecting calves from 2-6 months of age. Pneumonia that occurs in BRD characterized by fever, depression, and coughing, breathing difficulties and reduced appetite in pre weaned calves and heifers.

Polarization anisotropy in fiber-optic second harmonic generation microscopy

name: Gu, Min
Publisher: name: Swinburne
Year: 2024

description: We report the investigation and implementation of a compact second harmonic generation microscope that uses a single-mode fiber coupler and a double-clad photonic crystal fiber. Second harmonic polarization anisotropy through the fiber-optic microscope systems is quantitatively measured with KTP microcrystals, fish scale and rat tail tendon. It is demonstrated that the polarized second harmonic signals can be excited and collected through the single-mode fiber coupler to analyze the molecular orientations of structural proteins. It has been discovered that a double-clad photonic crystal fiber can preserve the linear polarization in the core, although a depolarization effect is observed in the inner cladding region. The feasibility of polarization anisotropy measurements in fiber-optic second harmonic generation microscopy will benefit the in vivo study of collagen-related diseases with a compact imaging probe.

description: In this article, we look at the option of using a stochastic optimisation technique, namely genetic algorithm (GA) in association with density functional theory (DFT) to find out the global minimum structures of (MgF2)n clusters with the range of n being between 2 and 10. To confirm whether the structures are indeed the acceptable ones, we go on to evaluate several properties like IR spectroscopic modes, vertical excitation energy, cluster formation energy, vertical ionisation potential and the HOMO–LUMO gap. We stress on the fact that an initial estimation of structure using GA, on two empirical potentials (with and without inclusion of polarisation), leads to a very quick convergence to structures which are quite close to the structures obtained from quantum chemical calculations done from the outset, such as using a DFT calculation. The general structural trend of these systems to form three-dimensional networks is also clear from our study. The lowest energy isomers of these clusters show preference for four-membered Mg2F2 and six-membered Mg3F3 rings. In the IR spectra of (MgF2)n clusters, a blueshift of the Mg–F symmetric stretch and a redshift of asymmetric Mg–F stretching as n increases are obtained.

Year: 2024

description: This article investigates the role of stress in English focusing on how stress functions in this language. In linguistics, word stress refers to the emphasis placed on a syllable within a word. This emphasis can affect the meaning, pronunciation, and overall flow of spoken language. For example, in the word "CON-duct" versus "con-DUCT," the stress on a different syllable changes the meaning from a noun to a verb. Word stress plays a crucial role in English and many other languages, contributing to effective communication and clarity in speech.
Polarization control of defect modes in three-dimensional woodpile photonic crystals

Publisher: name: Swinburne
Year: 2024

description: The symmetry of a Fabry-Perot-like planar cavity embedded within a three-dimensional (3D) woodpile photonic crystal prevents the observation of polarization effects. In this letter we propose a geometry to break the degeneracy of the Fabry-Perot-like cavity modes by introducing asymmetry. The introduction of a one-dimensional (ID) lattice to the centre of a planar cavity allows for distinct modes parallel (TE) and perpendicular (TM) to the layer. This hybrid 3D-1D-3D lattice structure exhibits a pronounced increase in the quality-factor, and in particular shows an increase of up to 50% more than that of a planar cavity for TM modes.

description: Finite-temperature behaviour of a hollow golden cage (HGC) plays a crucialrole in its potential applications as a catalyst, drug delivery agent, contrasting agent and so on. This physico-chemical property of HGCs is not well understood so far. In that context, Born–Oppenheimer molecular dynamics (BOMD) simulations are performed on a well-known ‘free-standing’ HGC. The cluster considered in this study is the ground state Au18 cluster (a cage with a diameter of about >5.5 Å). The results thus obtained are compared with the BOMD simulation results reported earlier on Au32 icosahedron cage, a conformation with a diameter of nearly. The sphericity of both the clusters is studied using a shape deformation parameter as a function of time and temperature. These results are supplemented by radial distribution function at various temperatures. The observations and analysis of results indicate that, both the clusters retain an HGC conformation from 300 to 400 K, admitting structural fluxionality by the Au18 cluster. Remarkably, the Au18 cluster is able to maintain its hollowness and sphericity up to a high temperature of 1000 K. Underlying structural and electronic properties influencing the individualistic behaviour of cages are highlighted. Composition of the frontier molecular orbitals and the charge distribution play a crucial role in the finite-temperature behaviour of the Au cages. The conclusions are supplemented by supporting calculations on another degenerate ground state Au18 hollow cage and a well-known pyramidal Au18 cage at 300 and 400 K.
CFD model simulation of bubble surface area flux in flotation column reactor in presence of minerals

Publisher: name: Swinburne

description: Bubble surface area flux (Sb) is one of the main design parameter in flotation column that typically employed to describe the gas dispersion properties, and it has a strong correlation with the flotation rate constant. There is a limited information available in the literature regarding the effect of particle type, density, wettability and concentration on Sb. In this paper, computational fluid dynamics (CFD) simulations are performed to study the gas–liquid–solid three-phase flow dynamics in flotation column by employing the Eulerian–Eulerian formulation with k-ε turbulence model. The model is developed by writing Fortran subroutine and incorporating then into the commercial CFD code AVL FIRE, v.2014. This paper studies the effects of superficial gas velocities and particle type, density, wettability and concentration on Sb and bubble concentration in the flotation column. The model has been validated against published experimental data. It was found that the CFD model was able to predict, where the response variable as indicated by R-Square value of 0.98. These results suggest that the developed CFD model is reasonable to describe the flotation column reactor. From the CFD results, it is also found that Sb decreased with increasing solid concentration and hydrophobicity, but increased with increasing superficial gas velocity. For example, approximately 28% reduction in the surface area flux is observed when coal concentration is increased from 0 to 10%, by volume. While for the same solid concentration and gas flow rate, the bubble surface area flux is approximately increased by 7% in the presences of sphalerite. A possible explanation for this might be that increasing solid concentration and hydrophobicity promotes the bubble coalescence rate leading to the increase in bubble size. Also, it was found that the bubble concentration would decrease with addition of hydrophobic particle (i.e., coal). For instance, under the same operating conditions, approximately 23% reduction in the bubble concentration is predicted when the system was working with hydrophobic particles. The results presented are useful for understanding flow dynamics of three-phase system and provide a basis for further development of CFD model for flotation column.

description: Empirical model potentials are found to be very useful for generating most competitive minima of large water clusters, whereas correlated (e.g. second order-Møller–Plesset perturbation (MP2) theory or higher) calculations are necessary for predicting their accurate energetics and vibrational features. The present study reports the structures and energetics of (H2O)32 clusters at MP2 level using aug-cc-pvDZ basis set, starting with low-lying structures generated from model potentials. Such high-end and accurate calculations are made feasible by the cost-effective fragment-based molecular tailoring approach (MTA) in conjunction with the grafting procedure. The latter is found to yield electronic energies with a sub-millihartree accuracy with reference to their full calculation counterparts. The vibrational spectra of nine low-lying (H2O)32 isomers are obtained from the corresponding MTA-based Hessian matrix. All these low-lying isomers show almost similar spectral features, which are in fair agreement with the experiment. The experimental spectrum of (H2O)32 is thus better understood from the vibrational features of this set of very closely spaced isomers. The present case study of (H2O)32 clearly demonstrates the efficacy in obtaining accurate structures, energetics and spectra at correlated level of theory by combining model potential-based structures with fragmentation methods.
title: The SPEDE electron spectrometer

description: This thesis presents SPEDE (SPectrometer for Electron DEtection) and documents its construction, testing and performance during commissioning at Jyv ̈askyl ̈a, Finland, before deployment at the HIE-ISOLDE facility at CERN coupled with the MINIBALL array to perform in-beam electron-gamma spectroscopy using post-accelerated radioactive ion beams. Results from the Coulomb excitation of 221Rn in 2012 are presented as an example of the need for the construction of a device like SPEDE. In-beam testing and initial commissioning experiments with stable beams took place in four stints during November, February, and May 2015, coupled with detectors from JUROGAMII. This spectrometer will help aid in fully understanding exotic regions of the nuclear chart such as regions with a high degree of octupole deformation, and in those nuclei exhibiting shape coexistence. For the first time, electron spectroscopy has been performed at the target position from states populated in accelerated nuclei via Coulomb excitation. The FWHM of SPEDE is approximately 7 keV at 320 keV, and Doppler correction was possible to improve Doppler broadened peaks to a resolution of 8.9 keV at a peak position of 186 and 196 keV. The results are intended to give the reader a full understanding of the detector and electronics, as well as the performance, capabilities, and usefulness of the spectrometer, both in simulated and in real-world situations.
Salience and social meaning in speech production and perception
Creators: name: Alderton, Roy
Publisher: name: Lancaster University
Year: 2020

description: Research has shown that phonetic features can index social meaning, yet less is known about whether this phenomenon occurs in the same way in speech production and speech perception. In particular, one of the factors that most seems to affect variables’ capacity for social meaning-making is the notion of salience. This thesis addresses the question of how phonetic variation points to social meaning in speech production and perception and what role salience plays in influencing this process. I investigate these issues using a sociophonetic study of two phonetic variables currently undergoing change in the South of England – /t/-glottalling and GOOSE-fronting – as produced and perceived by adolescents at a state school and a private school in Hampshire, UK. While the former is reported to be highly salient with strong socio-indexical relations, the latter is said not to be very salient and to lack associations with speakers’ social characteristics. The production results show that /t/-glottalling displays macro-sociological variation in the community, while GOOSE-fronting varies between peer groups within the private school. Both features can be used to index stances in interaction, but this effect is much stronger for /t/-glottalling. In perception, listeners were easily able to notice glottal /t/ in auditory stimuli and consistently associated it with a set of related social meanings, yet this was not the case for fronted GOOSE. The findings have implications for our understanding of how the social meanings of phonetic variables are produced and perceived by the same individuals, especially in the contexts of adolescent peer groups at school and social stratification between different types of school. I argue that researchers employing the construct of salience in sociolinguistics should acknowledge the limitations and different dimensions of the concept and operationalise these in their study design.

description: For the first time to our knowledge the observation of near-IR multiple higher-order stopgaps in three-dimensional photonio crystals (PhCs) fabricated using the direct-laser-writing method in thick chalcogenide glass films is reported. The fabrication and etching conditions necessary to realize well-defined structures are presented. The fabricated PhCs exhibit higher-order stopgaps, which are only evident in high-quality structures. The higher-order stopgaps observed permit these high-refractive-index and high-nonlinear PhCs to be used directly as functional photonic devices operating at telecommunication wavelengths without further miniaturizing structural dimensions.

Year: 2024

description: A method is reported for improving the spatial resolution and engineering the stop gaps of the inorganic-organic 3D woodpile photonic crystals (PhCs). The approach is based on the two-photon polymerization (2PP) of an inorganic-organic hybrid material and a post-thermal treatment (PTT) process. The effects of PTT on polymerized ID, 2D and 3D structures have been characterized. Ultimately, the feature size of the suspended rods has been reduced to ∼33 nm and the spatial resolution of inorganic-organic 3D woodpile PhCs has been improved from -150 nm to -86 nm. The approach is also demonstrated as a powerful tool to engineer the stop gaps of 3D PhCs. In particular, a combination of PTT and the threshold fabrication technique leads to the stop gap of a 3D woodpile PhC that can be tuned over a large wavelength range of -318 nm from the near-infrared to visible region.

description: At a time of new arising advancements, and spotting lights to blockchain innovation explicitly; many commitments happen. Blockchain has drawn in numerous analysts and specialists from different callings and disciplines, because of the strong qualities behind embracing such innovation. What's more, to plan a superior comprehension of it, numerous scientists are keen on characterizing the Blockchain-Based Programming Frameworks (BBSSs). Sadly, none of the accessible scientific categorizations in the writing considers the different Programming (SWE) viewpoints for building a BBSS. A blockchain educated authority (SME) may retain a particular perspective comprehension from every one of the connected scientific classifications, and to have a total comprehension of the different choices accessible for building a BBSS, they should flip from an asset to one more to gather the dissipated data they need. Thus, this paper expects to help the blockchain SMEs to verbalize a far reaching comprehension of the different and latest ideas and plan choices that anyone could hope to find, to execute or propose a BBSS arrangement. The scientific categorization is gotten from the key information and the major SWE perspectives which a BBSS implementer or specialist needs to consider, and consequently isn't one-sided to a particular SWE viewpoint.
Reduction of self-phase modulation in double-clad photonic crystal fiber for nonlinear optical endoscopy

Publisher: name: Swinburne
Year: 2024

description: Double-clad photonic crystal fiber and double-clad fiber have been widely used in multiphoton-excited fluorescence or second-harmonic generation (SHG) endoscopy. We provide a useful comparison of two fibers used in nonlinear optical microendoscopy. While a double-clad fiber is found to have a higher percentage of the output power from its core, which results in the efficient utilization of the power of the excitation laser, a double-clad photonic crystal fiber has a higher threshold of the nonlinearity, which effectively reduces the self-modulation effect and thus leads to a higher degree of polarization of the excitation beam. Consequently, the use of the double-clad photonic crystal fiber facilitates bright two-photon fluorescence imaging as well as polarized SHG imaging.

description: Many have suggested a bootstrap procedure for estimating the sampling variability of principal component analysis (PCA) results. However, when the number of measurements per subject (p) is much larger than the number of subjects (n), calculating and storing the leading principal components (PCs) from each bootstrap sample can be computationally infeasible. To address this, we outline methods for fast, exact calculation of bootstrap PCs, eigenvalues, and scores. Our methods leverage the fact that all bootstrap samples occupy the same n-dimensional subspace as the original sample. As a result, all bootstrap PCs are limited to the same n-dimensional subspace and can be efficiently represented by their low-dimensional coordinates in that subspace. Several uncertainty metrics can be computed solely based on the bootstrap distribution of these low-dimensional coordinates, without calculating or storing the p-dimensional bootstrap components. Fast bootstrap PCA is applied to a dataset of sleep electroencephalogram recordings (p = 900, n = 392), and to a dataset of brain magnetic resonance images (MRIs) (p ≈ 3 million, n = 352). For the MRI dataset, our method allows for standard errors for the first three PCs based on 1000 bootstrap samples to be calculated on a standard laptop in 47 min, as opposed to approximately 4 days with standard methods.

description: Eruca sativa Miller is a worldwide common alimentary plant (rocket leaves). The aim of this study was to correlate the potential in vitro scavenging activity of the E. sativa hydroalcoholic extract (HAE) with its in vivo hypoglycaemic effect. In DDPH free radical (DFR) and ferric-reducing antioxidant power assays, HAE in a concentration dependent manner (25–100 μg/mL) displayed a strong scavenging activity with maximum effect of 88% and 75% at 100 μg/mL, respectively. Daily administration of HAE (50 mg/kg; p.o.) in the in vivo model of alloxan-induced diabetic rabbits for 28 days showed significant reduction in glycaemia, also supported by recovery of body weight. In conclusion, our results give preliminary information on the potential use of this plant as a nutraceutical, useful to control and/or prevent a hyperglycaemic status.
title: A Study of the Effects of Position Resolution and Energy Resolution on Compton Imaging using a Single Planar Strip Detector
Creators: name: Wright, JP

Year: 2016

description: The feasibility of single element Compton imaging using a Double Sided Germanium Strip Detector (DSGSD) has been investigated, with potential use in assisting particle identification as part of Phase III DEGAS at DESPEC in mind. DEGAS is a proposed high-purity germanium tracking array for use in the DEcay SPECtroscopy (DESPEC) experiment at FAIR. The concept of γ-ray tracking within a DSGSD has been proved viable, with Compton images reconstructed from partial energy depositions within the detector volume. Using the raw positional information provided by the segmentation of the detector, initial source locations were unable to be resolved, with the resulting image displaying multiple ‘hotspots’ resulting from the selection criteria imposed. The causes of these features have been explored and explained in terms of scattering angles using the simulation package GAMOS. The effects of Pulse Shape Analysis, as a means of improving position sensitivity, have also been investigated, using a simulated database in con- junction with a grid search algorithm. Detailed electric field simulations were created, enabling a simulated pulse shape database to be generated using the ADL software package. Experimental data were sorted to locate potential Compton events, with charge pulses for each events stored using a digital electronics setup. Experimental pulses were compared to pulses from the simulated database using a FoM minimisation grid search algorithm. This improved the position resolution of interactions within the detector, thus improving the effectiveness of the resulting Compton reconstructions. With the application of PSA, initial source positions were located to within ∼ 10 mm, with the image resolution found to be of the order ∼ 100 mm for a range of initial γ-ray energies. Initial results appear promising, with future work required to improve the efficiency of the method. Additionally, Monte Carlo simulations have been performed to study the individual contributions of both energy and position resolution on the final reconstructed Compton image. Simulations were performed for three energy resolutions; 0, 3 and 50 keV, with a fixed position resolution of 2 × 2 × 10 mm, in addition to three position resolutions; 1, 2 and 5 mm3, with a fixed energy resolution of 5 keV. The results of these showed that the position sensitivity of the detector has a much more significant impact of both the location and resolution of the reconstructed Compton image.

description: Participation is an important theme in current democratic theory and there is burgeoning use of its institutional form, direct democracy, to legitimise political bodies and their decision-making. This thesis analyses the legislative design and implementation of two recent direct democracy innovations: the European Citizens Initiative (ECI) and the referenda in the European Union Act (EUA). The agenda setting ECI, which gives EU citizens the chance to propose legal acts of the Union, is the first supranational instrument of direct democracy, and the EUA contains the UK’s first ongoing legislative criteria that trigger a referendum. The duality of EU democracy is an essential aspect of its legitimisation. Two dichotomies are therefore used to frame the analysis of direct democracy in the EU: the supranational (direct) and intergovernmental (indirect) routes of EU legitimisation and the legitimisation of the EU’s constitutional framework and its daily authority. These dichotomies, and democratic criteria focussed on citizen participation and influence over the political agenda, support the analysis of the likely combined impact of the ECI and EUA on the dual EU democracy. The critical assessment of the legislative design of the ECI and of the Commission’s decision-making in relation to the ECI shows that institutional mediation and the EU’s duality have a significant impact on the potential to increase the influence of EU citizens on the EU political agenda, and to facilitate a challenge to established policy preferences. Similarly the critical analysis of the EUA referenda provisions indicate that the apparently strong opportunity to vote on the UK’s EU policy in a referendum is qualified in a number of respects by institutional control reflected in the legislation itself, and that the chance of citizen-led policy preferences is diminished. The thesis concludes with a combined analysis of the ECI and EUA to assess the joint impact of direct democracy on dual EU democracy through answering two questions: ‘What are their implications for the EU democratic paradigm?’, and ‘What is their influence together on EU democratic legitimacy?’. The overall findings are that the impact of the ECI and EUA, despite posing some challenges and despite their democratic potential, is likely to be heavily restricted as a result of institutional control and the EU’s political framework.

description: The recently introduced multireference equation of motion (MR-EOM) approach is combined with a simple treatment of spin–orbit coupling, as implemented in the ORCA program. The resulting multireference equation of motion spin–orbit coupling (MR-EOM-SOC) approach is applied to the first-row transition metal atoms Cr, Mn, Fe and Co, for which experimental data are readily available. Using the MR-EOM-SOC approach, the splittings in each L-S multiplet can be accurately assessed (root mean square (RMS) errors of about 70 cm−1). The RMS errors for J-specific excitation energies range from 414 to 783 cm−1 and are comparable to previously reported J-averaged MR-EOM results using the ACESII program. The MR-EOM approach is highly efficient. A typical MR-EOM calculation of a full spin–orbit spectrum takes about 2 CPU hours on a single processor of a 12-core node, consisting of Intel XEON 2.93 GHz CPUs with 12.3 MB of shared cache memory.

description: This research investigates how organisations where e-learning is already firmly established experience the adoption of mobile learning. Drawing on responses from training managers and sales and service staff, it investigates key aspects of mobile learning, as understood in organisations; how they perceive the relationship between mobile learning and e-learning provision; their key objectives for deploying mobile learning; and the dynamics of mobile learning practice as it is emerging. The project uses a multi-case study methodology with data collected from three corporate organisations in different sectors (healthcare, computing, and financial services). In each case, data is drawn from interviews with training managers and questionnaire responses from sales and service staff. Sharples’ framework for mobile learning, which focuses on the mobility of learners and learning as ‘conversations’, forms the analytical basis for the study. Three case reports are first presented, and then a cross-case analysis is conducted to draw out points of commonality and difference between the cases. My findings show that mobile learning is understood in the organisations through the lens of e-learning: while the two are not perceived as the same thing, the relationship is perceived to be close. While some barriers to adoption are technological, most concern social factors (stakeholder resistance and lack of leadership support). There is also a lack of use of collaborative aspects of mobile learning in emerging practices, even though respondents were aware that such possibilities existed. Most importantly, actual practices of mobile learning are driven more by the organisations’ business needs and how they have previously used e-learning, rather than their specific perceptions of mobile learning. The work contributes to existing research on mobile learning in the corporate sector (especially the perceived advantages and effectiveness of mobile learning, and challenges in adopting it), and in particular, the influence of context (social factors) on integrating mobile learning in organisations.

description: Nanometric plasmonic slits with stepped corrugations have been designed and fabricated to achieve plasmonic focusing and focal depth modulation. A scanning near-field optical microscope is employed to directly visualize the transmitted light from the slits. The near-field and far-field two-dimensional images taken at different planes parallel to the slit surface unambiguously demonstrated the focusing effect of the nanoslits. Furthermore, by forming stepped corrugations with either a concave or a convex profile on both sides of the slits, the phase of the transmitted beam can be effectively manipulated, thus allowing an accurate tuning of the focal depth.

description: Beneficial soil bacteria are able to colonize plant root systems promoting plant growth and increasing crop yield and nutrient uptake through a variety of mechanisms. These bacteria can be an alternative to chemical fertilizers without productivity loss. The objectives of this study were to test bacterial inoculants for their ability to promote nutrient uptake and/or plant growth of rice plants subjected to different rates of chemical fertilizer, and to determine whether inoculants could be an alternative to nitrogen fertilizers. To test the interaction between putatively beneficial bacteria and rice plants, field experiments were conducted with two isolates: AC32 (Herbaspirillum sp.) and UR51 (Rhizobium sp.), and different nitrogen fertilization conditions (0%, 50%, and 100% of urea). Satisfactory results were obtained in relation to the nutrient uptake by plants inoculated with both isolates, principally when the recommended amount of nitrogen fertilizer was 50% reduced. These bacterial strains were unable to increase plant growth and grain yield when plants were subjected to the high level of fertilization. This study indicated that the tested inoculant formulations can provide essential nutrients to plants, especially when the levels of nitrogen fertilizers are reduced.
