description: The normal gut microbiota has several important functions in host physiology and metabolism, and plays a key role in health and disease. Bifidobacteria, which are indigenous components of gastrointestinal microbiota, may play an important role in maintaining the well-being of the host although its precise function is very difficult to study. Its physiological and biochemical activities are controlled by many factors, particularly diet and environment.  
Adherence and colonization capacity are considered as contributing factors for immune modulation,
pathogen exclusion, and enhanced contact with the mucosa. In this way, bifidobacteria would fortify the microbiota that forms an integral part of the mucosal barrier and colonization resistance against pathogens.
Bifidobacteria are not only subjected to stressful conditions in industrial processes, but also in nature, where the ability to respond quickly to stress is essential for survival. Bifidobacteria, like other microorganisms, have evolved sensing systems for/and defences against stress that allow them to withstand harsh conditions and sudden environmental changes.
Bacterial stress responses rely on the coordinated expression of genes that alter various cellular processes and structures (e.g. DNA metabolism, housekeeping genes, cell-wall proteins, membrane composition) and act in concert to improve bacterial stress tolerance. The integration of these stress responses is accomplished by regulatory networks that allow the cell to react rapidly to various and sometimes complex environmental changes. This work examined the effect of important stressful conditions, such as changing pH and osmolarity, on the biosynthesis of cell wall proteins in B. pseudolongum subsp. globosum. These environmental factors all influence heavily the expression of BIFOP (BIFidobacterial Outer Proteins) in the cell-wall and can have an impact in the interaction with host. Also evidence has been collected linking the low concentration of sugar in the culture medium with the presence or absence of extracromosomal DNA.

description: Supermarkets and hypermarkets still represent a relatively new retailing format in Italy and in its Southern area in particular, where they were introduced decades later than in other Western countries, such as France and the UK in Europe, and the US in America. Nowadays, these retailers
have become large organisations potentially capable of influencing local development from an economic, social and urban perspective. The literature concerned with their effects on the local economy, in particular, has focused on labour markets, price dynamics, inter-type competition,
instead the impact on macroeconomic factors such as GDP, value added and investments in specific sectors, as agriculture, industry and services. This study tries to fill this gap by empirically investigating associations between key characteristics of these retailers and specific macroeconomic factors.

description: The use of scaffolds for Tissue Engineering (TE) is increasing due to their efficacy in helping the body rebuild damaged or diseased tissue. Hydroxyapatite (HA) is the most suitable bioactive ceramic to be used in orthopaedic reconstruction since it replicates the mineral component of the hard tissues, and it has therefore excellent biocompatibility properties. The temporal and spatial control of the tissue regeneration process is the limit to be overcome in order to treat large bone and
osteochondral defects. In this thesis we describe the realization of a magnetic scaffolds able to attract and take up growth factors or other bio-agents in vivo via a driving magnetic force. This concept involves the
use of magnetic nanoparticles (MNP) functionalized with selected growth factors or stem cells. These functionalized MNP act as shuttles transporting the bio-agents towards and inside the scaffold under the effect of the magnetic field, enhancing the control of tissue regeneration processes. This scaffold can be imagined as a fixed “station” that provides a unique possibility to adjust the scaffold activity to the specific needs of the healing tissue. Synthetic bone graft substitutes, made of collagen or biomineralized collagen (i.e. biomimetic Hydroxyapatite/collagen composites) were used as starting materials for the fabrication of magnetic scaffolds. These
materials are routinely used clinically to replace damaged or diseased cartilaginous or bone tissue. Our magnetization technique is based on a dip-coating process consisting in the infilling of biologically inspired porous scaffolds with aqueous biocompatible ferrofluids’ suspensions. In this
technique, the specific interconnected porosity of the scaffolds allows the ferrofluids to be drawn inside the structure by capillarity. A subsequent freeze-drying process allows the solvent elimination while keeping very nearly the original shape and porosity of the scaffolds. The
remaining magnetic nanoparticles, which are trapped in the structure, lead to the magnetization of the HA/Collagen scaffold. We demonstrate here the possibility to magnetize commercially available scaffolds up to magnetization values that are used in drug delivery processes. The preliminary biocompatibility test showed that the investigated scaffolds provide a suitable micro-environment for cells. The biocompatibility of scaffold facilitates the growth and
proliferation of osteogenic cells.

description: Geometric nonlinearities of flexure hinges introduced by large deflections often complicate the analysis of compliant mechanisms containing such members, and therefore, Pseudo-Rigid-Body Models (PRBMs)  have been well proposed and developed by Howell [1994] to analyze the characteristics of slender beams under large deflection. These models, however, fail to approximate the characteristics for the deep beams (short beams) or the other flexure hinges. Lobontiu's work [2001] contributed to the diverse flexure hinge analysis building on the assumptions of small deflection, which also limits the application range of these flexure hinges and cannot analyze the stiffness and stress characteristics of these flexure hinges for large deflection. 
Therefore, the objective of this thesis is to analyze flexure hinges considering both the effects of large-deflection and shear force, which guides the design of flexure-based compliant mechanisms. The main work conducted in the thesis is outlined as follows.
1. Three popular types of flexure hinges: (circular flexure hinges, elliptical flexure hinges and corner-filleted flexure hinges) are chosen for analysis at first.
2. Commercial software (Comsol) based Finite Element Analysis (FEA) method is then used for correcting the errors produced by the equations proposed by Lobontiu when the chosen flexure hinges suffer from large deformation.
3. Three sets of generic design equations for the three types of flexure hinges are further proposed on the basis of stiffness and stress characteristics from the FEA results.
4. A flexure-based four-bar compliant mechanism is finally studied and modeled using the proposed generic design equations. The load-displacement relationships are verified by a numerical example. The results show that a maximum error about the relationship between moment and rotation deformation is less than 3.4% for a flexure hinge, and it is lower than 5% for the four-bar compliant mechanism compared with the FEA results.

description: We note that the essential idea of inflation, that the universe underwent a brief period of accelerated expansion followed by a long period of decelerated expansion, can be encapsulated in a "closure condition" which relates the amount of accelerated expansion during inflation to the amount of decelerated expansion afterward. We present a protocol for systematically testing the validity of this condition observationally.

description: Pharmaceuticals and heavy metals are contaminants present in groundwaters, which are the main source of drinking water in most parts of the world. In the northwest region of Spain, Galicia, groundwater harvesting is a common practice for drinking water supply, crop irrigation, cattle watering, as well as recreational use such as filling pools. In order to assess the quality of Galician groundwaters, the presence of 21 pharmaceuticals and 10 heavy metals was analysed by UPLC-MS/MS and ICP/MS methods, respectively, in a total of 118 groundwater samples from private wells. Seventeen of the 21 compounds studied were detected in 28% of the samples, with the highest presence of pharmaceuticals belonging to the antimicrobial group (52%), specifically the sulphonamides group in a range of concentration between 21 and 14.9 ng/L. In addition, 30% of the samples contained at least one heavy metal (Mn, As and Fe) above the legally permitted levels. Evaluation of the risk associated with the consumption of the analysed groundwater indicated no human risk for any of the detected pharmaceuticals but high cancer risk for children due to Cd, Cr and As concentrations was observe

description: Al principio iura novit curia si assegnano tradizionalmente due significati: il giudice conosce le norme, quindi le parti non hanno onori al riguardo, e il giudice non è vincolato dalle indicazioni delle parti, quanto alle norme di diritto da applicare. 
La tesi delimita inizialmente la nozione di questione di diritto, quindi affronta partitamente due problemi che si pongono con riferimento alle questioni di diritto e che sono soliti essere risolti con il richiamo al principio iura novit curia: la conoscenza delle norme da una parte e la qualificazione giuridica della domanda e quindi della situazione soggettiva dall’altra. 
Quanto alla conoscenza delle norme, motivata la scelta per l’obbligatorietà della conoscenza ufficiosa di tutte le fonti di diritto, la tesi verifica la regola in relazione alle diverse fonti descrivendone la disciplina. 
Quanto alla qualificazione giuridica della domanda, la tesi, verificata la vigenza del principio iura novit curia, descrive sul piano processuale le relazioni del potere-dovere di qualificazione giuridica a) individuandone i limiti oggettivi, ricompresi nei limiti della domanda, e risultanti dal confronto con la regola della corrispondenza del chiesto con il pronunciato, del concorso di diritti, della natura autodeterminata dei diritti, b) tracciandone le modalità legittime di esercizio in conformità al principio del contradditorio; c) verificandone i limiti esterni, ravvisati in quegli istituti che impediscono al giudice di formulare un giudizio sulla questione di diritto: le sentenze non definitive su questioni di diritto, il principio di diritto, il giudicato interno e i limiti alla cognizione del giudice dell’impugnazione tra i  gradi di giudizio.
description: Traditionally the meaning of the iura novit curia principle is twofold. First, the judge has the duty to search the source of law which is applicable to the case he is facing; second, the judge is not bounded by the legal profiles or suggestions which the parties of the proceeding indicate.
The present Ph.D. thesis tries to define the concept of “legal issue” and to define the field of application of the iura novit curia principle.
The issue represented by the knowledge of the law is considered in conjunction with various sources of law.
The issue of the “legal qualification” is evaluated with reference to
a) the limits internal to the power of the judge (also with regard to the nemo iudex sine actore principle), b) the way to exercise the above-mentioned power in accordance with the due process principle and with the right of the parties to be heard, c) the limits external to the power to be exercised in relation with the other procedural topics involving legal procedural issues.
Pollen collection and pollen transport by native bees in temperate deciduous forests
Creators: name: Weinman, Lucia Rae
Publisher: name: No Publisher Supplied

description: Bees’ collection of pollen is an especially important component of their dietaryniche, affecting bee species’ responses to environmental change, the contributions of bee populations to the stability of plant-pollinator communities, and individual bee foragers’ patterns of heterospecific pollen transfer among their host plants. For my dissertation, I analyze bees’ pollen collection to inform conservation of an understudied bee fauna, and explore the implications of bees’ pollen diet breadth for bees’ effects on plants and plant communities.In my first chapter, I characterize the pollen collection of bee genera associated with temperate deciduous forests, providing the largest and most spatially extensive source of data on bees’ use of floral resources within mature deciduous forest habitat in North America. My findings reveal differences among dominant forest bee genera in their use of floral resources, especially in their collection of pollen, and confirm the importance of canopy tree species and shrubs for bees in forest habitats, even in forests with healthy understory flowering plant communities.In my second chapter, I measure how pollen diet breadth in three native bee species changes with scale of biological organization. I found that diet breadth increased with scale: bee populations were consistently comprised of individuals that predominantly collected pollen from only one or two plant taxa per foraging trip, and regionally bees’ pollen diet breadth was much wider than in any given population. I discuss the implications of these results for bees’ patterns of heterospecific pollen transfer in generalized plant-pollinator communities, and the effects of regional declines of relatively specialized bee species on these communities.In my third chapter, I assess how bees’ specialization on individual foraging trips affects the efficiency with which they transport pollen for pollen host plants. I find that, on individual foraging trips, bee individuals transport proportionally less pollen for the host plants on which they specialize. This result suggests that foraging boutspecialization, which is known to reduce heterospecific pollen transfer, also results in less efficient pollen transport. Thus, bee foragers that visit predominantly one plant species may have contrasting effects on that plant's fitness.

description: Adaptive collection of data is commonplace in applications throughout science and engineering. From the point of view of statistical inference, however, adaptive data collection induces memory and correlation in the samples, and poses significant challenge. We consider the high-dimensional linear regression, where the samples are collected adaptively, and the sample size n can be smaller than p, the number of covariates. In this setting, there are two distinct sources of bias: the first due to regularization imposed for consistent estimation, for example, using the LASSO, and the second due to adaptivity in collecting the samples. We propose “online debiasing,” a general procedure for estimators such as the LASSO, which addresses both sources of bias. In two concrete contexts (i) time series analysis and (ii) batched data collection, we demonstrate that online debiasing optimally debiases the LASSO estimate when the underlying parameter θ0 has sparsity of order o(n/ log p). In this regime, the debiased estimator can be used to compute p-values and confidence intervals of optimal size.

The joint effects of task complexity and response probability on response latency : a test of the existence of a defensive strategy in a two-choice reaction time task
Creators: name: Leech, Maureen I.
Publisher: name: University of British Columbia
Year: 2010

description: The main purpose of this study was to determine if subjects would employ a defensive type strategy in a two-choice reaction time task using tasks of unequal response complexity. The methodology used to investigate this problem involved examining the joint effects of two levels of task complexity and eight levels of response probability on response latency in one simple and seven choice experimental conditions. The hypothesized effects of response probability on response latency for tasks of unequal complexity are summarized as follows: (1) below a probability level of .50, response latency was expected to decrease as response probability decreased, and (2) above a .50 probability level no significant increase or decrease in response latency relative to the equal probability level was expected. The experimental task was a discrete, two-choice reaction time task, in which subjects were required to depress several response keys in a predetermined order following the onset of one of two possible stimulus lights. Two tasks of varying complexity were used: (1) a simple task involving two response keys only, and" (2) a complex task requiring the depression of five response keys in a specific order. Probability levels of 1.0, .90, .75, .60, .50, .40, .25, .10 provided eight experimental conditions under which the two tasks were performed. Sixteen male students from the University of British Columbia served as subjects. The empirical results did not provide support for the predicted hypotheses. It was found that for tasks of unequal complexity, subjects did not adopt a defensive strategy by preparing for the more difficult or less probable response. Results for both tasks illustrated a classical probability effect, i.e., an increase in probability results in a decrease in response latency, contrary to the predicted results for tasks of unequal complexity. Also, the extreme probability levels of .90 and .10 had a marked effect on the response latency for both tasks with the simple task showing greater variability than the complex task due to these probability levels. Data from this experiment tended to support the premise that response probability is a decreasing function of task complexity, i.e., the more complex the task the less effect response probability has on the resulting response latency.

Newtonian Fractional-Dimension Gravity and Galaxies without Dark Matter

description: We apply Newtonian Fractional-Dimension Gravity (NFDG), an alternative gravitational model, to some notable cases of galaxies with little or no dark matter. In the case of the ultra-diffuse galaxy AGC 114905, we show that NFDG methods can effectively reproduce the observed rotation curve, by using a variable fractional dimension $D\left (R\right )$ as was done for other galaxies in previous studies. For AGC 114905, we obtain a variable dimension in the range $D \approx 2.2 -3.2$, but our fixed $D =3$ curve can still fit all the experimental data within their error bars. This confirms other studies indicating that the dynamics of this galaxy can be described almost entirely by the baryonic mass distribution alone. However, our NFDG model explains the residual discrepancies without using any dark matter component. In the case of NGC 1052-DF2, we use an argument based on the NFDG extension of the virial theorem applied to the velocity dispersion of globular clusters showing that, in general, discrepancies between observed and predicted velocity dispersions can be attributed to an overall fractal dimension $D <3$ of the astrophysical structure considered and not to the presence of dark matter. For NGC 1052-DF2 we estimate $D \approx 2.9$, thus confirming that this galaxy almost follows standard Newtonian behavior. We also consider the case of the Bullet Cluster merger (1E0657-56), assumed to be one of the strongest proofs of dark matter existence. A simplified but effective NFDG model of the collision shows that the observed infall velocity of this merger can be explained by a fractional dimension of the system in the range $D \simeq 2.4 -2.5$, again without using any dark matter.

description: Using a large deviations approach we calculate the probability distribution of the mutual information of MIMO channels in the limit of large antenna numbers. In contrast to previous methods that only focused at the distribution close to its mean (thus obtaining an asymptotically Gaussian distribution), we calculate the full distribution, including its tails which strongly deviate from the Gaussian behavior near the mean. The resulting distribution interpolates seamlessly between the Gaussian approximation for rates $R$ close to the ergodic value of the mutual information and the approach of Zheng and Tse for large signal to noise ratios $ρ$. This calculation provides us with a tool to obtain outage probabilities analytically at any point in the $(R, ρ, N)$ parameter space, as long as the number of antennas $N$ is not too small. In addition, this method also yields the probability distribution of eigenvalues constrained in the subspace where the mutual information per antenna is fixed to $R$ for a given $ρ$. Quite remarkably, this eigenvalue density is of the form of the Marcenko-Pastur distribution with square-root singularities, and it depends on the values of $R$ and $ρ$.

description: We present a combined study of thermal expansion and resistance fluctuation spectroscopy measurements exploring the static and dynamic aspects of the charge-glass formation in the quasi-two-dimensional organic conductors $θ$-(BEDT-TTF)$_2$$MM^\prime$(SCN)$_4$ with $M$ = Cs and $M^\prime$ = Co,Zn. In these materials, the emergence of a novel charge-glass state so far has been interpreted in purely electronic terms by considering the strong frustration of the Coulomb interactions on a triangular lattice. Contrary to this view, we provide comprehensive evidence for the involvement of a \textit{structural} glass-like transition at $T_{\text{g}} \sim 90-100\,$K. This glassy transition can be assigned to the freezing of structural conformations of the ethylene endgroups in the donor molecule with an activation energy of $E_{\rm{a}}\approx 0.32\,$eV, and the concomitant slowing down of the charge carrier dynamics is well described by a model of non-exponential kinetics. These findings discolse an important aspect of the phase diagram and renders the current understanding of the charge-glass state in the whole family of $θ$-(BEDT-TTF)$_2MM^\prime$(SCN)$_4$ incomplete. Our results suggest that the entanglement of slow structural and charge-cluster dynamics due to the intimate coupling of lattice and electronic degrees of freedom determine the charge-glass formation under geometric frustration.

description: We analyse recently acquired near-infrared Hubble Space Telescope imaging of the GOODS-South field to search for star forming galaxies at z~7.0. By comparing WFC 3 0.98 micron Y-band images with ACS z-band (0.85 micron) images, we identify objects with colours consistent with Lyman break galaxies at z~6.4-7.4. This new data covers an area five times larger than that previously reported in the WFC3 imaging of the Hubble Ultra Deep Field, and affords a valuable constraint on the bright end of the luminosity function. Using additional imaging of the region in the ACS B, V and i-bands from GOODS v2.0 and the WFC3 J-band we attempt to remove any low-redshift interlopers. Our selection criteria yields 6 candidates brighter than Y_AB = 27.0, of which all except one are detected in the ACS z-band imaging and are thus unlikely to be transients. Assuming all 6 candidates are at z~7 this implies a surface density of objects brighter than Y_AB = 27.0 of 0.30\pm0.12 arcmin-2, a value significantly smaller than the prediction from the z ~ 6 luminosity function. This suggests continued evolution of the bright end of the luminosity function between z = 6 to 7, with number densities lower at higher redshift.

description: Based on density functional theory calculations, we elucidated the origin of multifunctional properties for cubic antiperovskites with noncollinear magnetic ground states, which can be attributed to strong isotropic and anisotropic magnetostructural coupling. Of 54 stable magnetic antiperovskites M3XZ (M = Cr, Mn, Fe, Co, and Ni; X = selected elements from Li to Bi except for noble gases and 4f rare-earth metals; and Z = C and N), 14 are found to exhibit the Γ4g/Γ5g (i.e., characterized by irreducible representations) antiferromagnetic magnetic configurations driven by frustrated exchange coupling and strong magnetocrystalline anisotropy. Using the magnetic deformation as an effective proxy, the isotropic magnetostructural coupling is characterized, and it is observed that the paramagnetic state is critical to understand the experimentally observed negative thermal expansion and to predict the magnetocaloric performance. Moreover, the piezomagnetic and piezospintronic effects induced by biaxial strain are investigated. It is revealed that there is not a strong correlation between the induced magnetization and anomalous Hall conductivities by the imposed strain. Interestingly, the anomalous Hall/Nernst conductivities can be significantly tailored by the applied strain due to the fine-tuning of the Weyl points energies, leading to promising spintronic applications.

Kinematics and dynamics of disclination lines in three-dimensional nematics

description: An exact kinematic law for the motion of disclination lines in nematic liquid crystals as a function of the tensor order parameter $\mathbf{Q}$ is derived. Unlike other order parameter fields that become singular at their respective defect cores, the tensor order parameter remains regular. Following earlier experimental and theoretical work, the disclination core is defined to be the line where the uniaxial and biaxial order parameters are equal, or equivalently, where the two largest eigenvalues of $\mathbf{Q}$ cross. This allows an exact expression relating the velocity of the line to spatial and temporal derivatives of $\mathbf{Q}$ on the line, to be specified by a dynamical model for the evolution of the nematic. By introducing a linear core approximation for $\mathbf{Q}$, analytical results are given for several prototypical configurations, including line interactions and motion, loop annihilation, and the response to external fields and shear flows. Behaviour that follows from topological constraints or defect geometry is highlighted. The analytic results are shown to be in agreement with three dimensional numerical calculations based on a singular Maier-Saupe free energy that allows for anisotropic elasticity.

A comparison of six methods of stretch on the passive range of hip flexion
Creators: name: Russell, Keith Wayne
Publisher: name: University of British Columbia
Year: 2010

description: A theoretical model stating that one must decrease resistance in a target area (area to he stretched) or increase the ability to overcome that resistance (strength) in order to positively alter range of joint movement was designed and an experiment set up to begin testing this model. It was discussed that there are two distinct ranges of joint movements PASSIVE being that range attained with the aid of some external force (a partner or gravity) and ACTIVE being that range attained by voluntary muscle contraction. It was also discussed that most methods of stretching could likewise be classified as either ACTIVE METHODS or PASSIVE METHODS. It was the purpose of this study to research the effects of six methods of stretch on the passive range of right hip flexion of 119 volunteer college women. Approximately 20 subjects were randomly assigned to each one of seven treatment groups. All subjects were measured before treatments were initiated and after treatments had ceased at the end of the study. Six of the groups were each assigned to a stretching regimen which was practiced in a lab ten minutes a day, three days a week for three weeks. All subjects, including the control group, were tested pre and post treatment on the first day of each week. The methods that were tested were divided into: active methods in which the subject actively mobilized their leg (Active P.N.F. and Spring Stretch); passive methods in which the partner mobilized the subjects leg (Relaxation, Passive P.N.F. and Prolonged Stretch); and a combination method in which the partner mobilized the subjects leg and then the subject actively tried to maintain the range attained (Passive Lift-Active Hold). All treatment groups showed a significant increase in their range of hip flexion though the mean increase of the treatment groups was significantly greater than the mean increase of the control group. The three passive methods (Relaxation, Passive P.N.F. and Prolonged Stretch) and the combination method (Passive Lift-Active Hold) were all equally effective in increasing passive range (only 1.3° between highest and lowest). The mean gain of the three passive methods was significantly greater than the mean gain of the two active methods.

Electron mobility in n-doped zinc sulphide
Creators: name: Rodrigues, Clóves Gonçalves

Year: 2021
Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: A study of the mobility of n-doped wurtzite and zincblende ZnS is reported. We have determined nonequilibrium thermodynamic state of the ZnS, driven far away from equilibrium by a strong electric field, in the steady state. The dependence of the mobility (which depends on the nonequilibrium thermodynamic state of the sample) on the electric field strength is derived, which decreases with the strength of electric field. We analyzed the contributions to the mobility arising out of the different channels of electron scattering, namely, the polar optic, deformation, interactions with the phonons, and with ionized impurities. The case of n-ZnS WZ and ZB have been analyzed: as expected the main contribution comes from the polar-optic interactions in this strong-polar semiconductor. The other interactions are in decreasing order, the deformation acoustic and the one due to impurities.

The Solar System, Exoplanets, and Astrobiology

description: Abstract: Measured spectral shifts due to intrinsic stellar variability (e.g., pulsations, granulation) and activity (e.g., spots, plages) are the largest source of error for extreme-precision radial-velocity (EPRV) exoplanet detection. Several methods are designed to disentangle stellar signals from true center-of-mass shifts due to planets. The Extreme-precision Spectrograph (EXPRES) Stellar Signals Project (ESSP) presents a self-consistent comparison of 22 different methods tested on the same extreme-precision spectroscopic data from EXPRES. Methods derived new activity indicators, constructed models for mapping an indicator to the needed radial-velocity (RV) correction, or separated out shape- and shift-driven RV components. Since no ground truth is known when using real data, relative method performance is assessed using the total and nightly scatter of returned RVs and agreement between the results of different methods. Nearly all submitted methods return a lower RV rms than classic linear decorrelation, but no method is yet consistently reducing the RV rms to sub-meter-per-second levels. There is a concerning lack of agreement between the RVs returned by different methods. These results suggest that continued progress in this field necessitates increased interpretability of methods, high-cadence data to capture stellar signals at all timescales, and continued tests like the ESSP using consistent data sets with more advanced metrics for method performance. Future comparisons should make use of various well-characterized data sets—such as solar data or data with known injected planetary and/or stellar signals—to better understand method performance and whether planetary signals are preserved.

description: Laser-induced fluorescence excitation spectrum of NiS in the wavelength range of 450 - 560 nm has been recorded and analyzed. Thirty-five vibronic transition bands have been observed, 29 of which are reported for the first time. Rotational analyses indicated that all the observed bands can be attributable to the [Omega = 0] - X^3 Sigma^- transitions of ^58 NiS (and ^60 NiS). Twenty-five bands have been suggested to be grouped into four vibrational progressions. Furthermore, through dispersed fluorescence measurements we directly obtained the energies for the ground-state vibrational levels up to v" = 6 as well as the vibrational frequency and the anharmonicity constant for the ground state of ^58 NiS.
