Effect of Different GA3 Concentration and Frequency on Growth, Flowering and Yield in Gaillardia (Gaillardia pulchella Foug.) Cv. Lorenziana

The present experiment was conducted at the Horticultural Instructional Farm, Department of Horticulture, J.A. U. , Junagadh during the winter 2004-05. The experiment comprised of ten treatments, viz., three concentrations of GA3 (50, 150, 250 ppm) at three frequencies (single, double and triple spray at 30, 45 and 60 days from transplanting) and control. Each treatment was replicated thrice in randomized block design. Of the different treatments, GA3 250 ppm single spray recorded maximum plant height and plant spread. Number of branches per plant was highest under double spray of GA3 at 50 ppm. Longest flowering duration, maximum flower diameter and maximum shelf-life were observed with single spray of 250 ppm GA3. It also registered maximum number and weight of flowers per plant besides highest flower yield.
Modeling the influence of basketball players’ offense roles on team performance

This study aimed to (1) use the clustering method to build a classification model based on the play-type data of basketball players, to classify native and foreign players into different offensive roles; (2) use the clustered offensive role model to investigate how different offensive roles influence team performance. The sample was drawn from 20 teams spanning five seasons (2017–2021) in the Chinese Basketball Association, comprising 823 native and 228 foreign players. The clustering results obtained fourteen offensive roles for native players and five for foreign players. Subsequent analyses revealed that the offensive roles of two native player clusters, namely N6 Spot-up Wings who Attack (OR = 3.281, p < 0.05) and N13 Bigs who Cut to the Rim (OR = 4.272, p < 0.05), significantly influenced team performance. Conversely, no significant impact was observed for foreign players. The findings of this study offer novel insights into player dynamics and offer coaches a fresh perspective on team composition.
Investigating the Effect of Operational Variables on the Yield, Characterization, and Properties of End-of-Life Olive Stone Biomass Pyrolysis Products

In recent years, biomass has emerged as a promising raw material to produce various products, including hydrocarbons, platform chemicals, and fuels. However, a more comprehensive evaluation of the potential production of desirable value-added products and chemical intermediates is required. For these reasons, this study aimed to investigate the impact of various operating parameters on the pyrolysis of end-of-life olive stone, an agriculture and food industry waste, using a tubular quartz reactor operated at 773 K. The results revealed that the product compositions were comparable under batch or semi-batch nitrogen feeding conditions and with reaction times of 1 or 3 h. The product distribution and composition were significantly influenced by changes in the heating rate from 5 to 50 K min−1, while the effect of changing the biomass particle size from 0.3 to 5 mm was negligible in the semi-batch test. This work provides a comprehensive understanding of the relationship between pyrolysis operational parameters and obtained product distribution and composition. Moreover, the results confirmed the possible exploitation of end-of-life olive stone waste to produce high-added value compounds in the zero-waste strategy and biorefinery concept.
SYSTEM DEVELOPERS' NATURE OF WORK CHARACTERISTICS AND THEIR RELATIONSHIP WITH ORGANIZATIONAL COMMITMENT AND JOB SATISFACTION

IT professionals’ level of organizational commitment and job satisfaction is important in minimizing turnover, improving job performance, minimizing absenteeism, and increasing the level of job involvement. This study explores various nature of work characteristics as a contributing factor to IT professionals’ organizational commitment and job satisfaction. Nature of work for the IT context of systems development is specified in this study as meaningfulness of work, task autonomy, task feedback, the level of group cohesion, and the level of role stress. Data were gathered from a survey of 124 IT professionals in systems development roles to capture perceptions regarding the specified nature of work constructs on job satisfaction and organizational commitment. The results of this study indicate that organizational commitment is positively related to job satisfaction and meaningfulness of work and negatively related to role stress. The results also indicate that job satisfaction is positively related to group cohesion and negatively related to role stress. Findings extend prior research by assessing the individual impact of specific nature of work characteristics on IT professionals’ job satisfaction and organizational commitment and providing new insight into group cohesion for the IT context. IT managers can use this information to increase employee organizational commitment and/or job satisfaction by considering role stress, group cohesion, and job characteristics when making project assignment and job/work design decisions.
New News is Bad News

An increase in the novelty of news predicts negative stock market returns and negative macroeconomic outcomes over the next year. We quantify news novelty - changes in the distribution of news text - through an entropy measure, calculated using a recurrent neural network applied to a large news corpus. Entropy is a better out-of-sample predictor of market returns than a collection of standard measures. Cross-sectional entropy exposure carries a negative risk premium, suggesting that assets that positively covary with entropy hedge the aggregate risk associated with shifting news language. Entropy risk cannot be explained by existing long-short factors.
On The Genesis and Predictability of Hurricane Julia (2010)

Title of dissertation: ON THE GENESIS AND PREDICTABILITY OF HURRICANE JULIA (2010) Stefan Francis Cecelski, Doctor of Philosophy, 2014 Dissertation directed by: Professor Da-Lin Zhang Department of Atmospheric and Oceanic Science Tropical cyclogenesis (TCG) continues to be one of the least understood processes in tropical meteorology today. While a robust theoretical framework for TCG within African Easterly Waves (AEWs) has recently been developed, little work explores the mesoscale processes and interactions with the AEW during TCG. This study investigates the TCG of Hurricane Julia from the 2010 north Atlantic hurricane season using a series of high-resolution model simulation with the finest grid size of 1 km. In addition to a control simulation used to study the mesoscale processes during TCG, 20 ensemble simulations are conducted to identify key dynamical and thermodynamical processes taking place during TCG. These ensembles also serve to quantify the predictability of TCG while determining the processes responsible for ensemble solution disagreements. It is found that the TCG of Hurricane Julia is triggered by the pronounced upper-tropospheric warming associated with organized deep convection. The upperlevel warming is able to intensify and become a meso-α-scale feature due to a stormscale outflow beyond the Rossby radius of deformation. The simulation confirms previous ideas by demonstrating that the intersection of the AEW’s trough axis and critical latitude is a preferred location for TCG, while supplementing such work by illustrating the importance of upper-tropospheric warming and meso-α-scale surface pressure falls during TCG. Ensemble simulations further elaborate on the mechanisms by depicting substantial parametric differences between the stronger and weaker members. The dominant pattern of mean sea-level pressure (MSLP) ensemble differences is associated with the intensity of the pre-tropical depression (preTD), explaining nearly half of the total variance at the time of TCG. Similar patterns of differences are found for the low-level absolute vorticity and upper-tropospheric temperature anomalies. An additional sensitivity simulation removing the latent heat of fusion associated with deposition results in significant changes to the TCG process. It is shown that the fusion heating occurring during deposition is important for the uppertropospheric thermodynamic changes occurring during TCG and thus, yields fundamental changes to structure and intensity of deep convection. Overall, removing fusion heating from deposition results in a weaker MSLP disturbance and one that is not self-sustaining. ON THE GENESIS AND PREDICTABILITY OF HURRICANE JULIA (2010)
DER Capacity Assessment of Active Distribution Systems Using Dynamic Operating Envelopes

The increasing deployment of distributed energy resources (DER) within electricity distribution systems can push them outside their safe operational limits. This urges the distribution system operators (DSO) to perform a DER capacity assessment that utilises the network’s full potential to accommodate more DER while ensuring the network’s safety. However, this is a challenging task as the DER units are mostly consumer-owned and therefore the DSO does not have control over them. To overcome this challenge, this paper first develops dynamic operating envelopes (DOEs). A DOE is a convex set defining acceptable real and reactive powers exchange with the grid at a consumer connection point without violating any network constraints. We propose a novel methodology to calculate a DOE by applying the right-hand side decomposition technique through which we allocate the network’s capacity to mutually independent consumers. We then build a hierarchical DER capacity assessment within DOEs that considers the uncertainty of solar power and demand when making investment decisions. In the proposed framework, the consumers are then free to make their decisions as long as they comply with their DOEs.
EFECTO DE LA TURBIDEZ EN LA PRODUCTIVIDAD PRIMARIA EN ~0s ESTACIONES EN EL AREA DEL DELTA DEL Rio COLORADO EFFECT OF TURBIDITY ON PRIMARY PRODUCTIVITY AT TWO STATIONS IN THE AREA OF THE COLORADO RIVER DELTA

Most coastal lagoons that present high tide intervals and high turbulent kinetic energy have high turbidity and, therefore, light is a limiting factor for primary productivity. The Colorado River Delta has been reported with high turbidity values. Our purpose is to estimate the effect of turbidity on primary productivity. We took water samples from two locations within the Colorado River Delta (one turbid and another less turbid). We carried out daily experiments on primary productivity with the 14C technique during spring and neap tides, from I5 to 22 May, I99 I. We used artificial light incubators with lamps of cool white constant light with 66.33 uE m-* s-’ of irradiance and another with a stroboscopic lamp with white xenon light with 66.17 uE mm2 s-’ of irradiance. In general, in the samples from the high turbid location we found a higher concentration of chlorophyll a and a higher concentration of chlorophyll a per cell. In the incubations with the stroboscopic lamp, the samples from the
Molecular characterization and differential effects of levofloxacin and ciprofloxacin on the potential for developing quinolone resistance among clinical Pseudomonas aeruginosa isolates

Background Fluoroquinolones are some of the most used antimicrobial agents for the treatment of Pseudomonas aeruginosa. This study aimed at exploring the differential activity of ciprofloxacin and levofloxacin on the selection of resistance among P. aeruginosa isolates at our medical center. Methods 233 P. aeruginosa clinical isolates were included in this study. Antimicrobial susceptibility testing (AST) was done using disk diffusion and broth microdilution assays. Random Amplification of Polymorphic DNA (RAPD) was done to determine the genetic relatedness between the isolates. Induction of resistance against ciprofloxacin and levofloxacin was done on 19 isolates. Fitness cost assay was done on the 38 induced mutants and their parental isolates. Finally, whole genome sequencing was done on 16 induced mutants and their 8 parental isolates. Results AST results showed that aztreonam had the highest non-susceptibility. RAPD results identified 18 clusters. The 19 P. aeruginosa isolates that were induced against ciprofloxacin and levofloxacin yielded MICs ranging between 16 and 256 μg/mL. Levofloxacin required fewer passages in 10 isolates and the same number of passages in 9 isolates as compared to ciprofloxacin to reach their breakpoints. Fitness cost results showed that 12 and 10 induced mutants against ciprofloxacin and levofloxacin, respectively, had higher fitness cost when compared to their parental isolates. Whole genome sequencing results showed that resistance to ciprofloxacin and levofloxacin in sequenced mutants were mainly associated with alterations in gyrA, gyrB and parC genes. Conclusion Understanding resistance patterns and risk factors associated with infections is crucial to decrease the emerging threat of antimicrobial resistance.
Sequential calibration of material constitutive model using mixed-effects calibration

Identifying model parameters is nowadays intrinsically linked with quantifying the associated uncertainties. While classical methods allow to handle some types of uncertainties such as experimental noise, they are not designed to take into account the variability between the different test specimens, significant in particular for composites materials. The estimation of the impact of this intrinsic variability on the material properties can be achieved using population approaches where this variability is modeled by a probability distribution (e.g., a multivariate Gaussian distribution). The objective is to calibrate this distribution (or equivalently its parameters for a parametric distribution). Among the estimation methods can be found mixed-effects models where the parameters that characterize each replication are decomposed between the population averaged behavior (called fixed-effects) and the impact of material variability (called random-effects). Yet, when the number of model parameters or the computational time of a single run of the simulations increases (for multiaxial models for instance), the simultaneous, global identification of all the material parameters is difficult because of the number of unknown quantities to estimate and because of the required model evaluations. Furthermore, the parameters do not have the same influence on the material constitutive model depending for instance on the nature of the load (e.g., tension, compression). The method proposed in this paper enables to calibrate the model on multiple experiments. It decomposes the overall calibration problem into a sequence of calibrations, each subproblem allowing to calibrate the joint distribution of a subset of the model parameters. The calibration process is eased as the number as the number of unknown parameters is reduced compared to the full problem. The proposed calibration process is applied to an orthotropic elastic model with non linear longitudinal behavior, for a unidirectional composite ply made of carbon fibers and epoxy resin. The ability of the method to sequentially estimate the model parameters distribution is investigated. Its capability to ensure consistency throughout the calibration process is also discussed. Results show that the methodology allows to handle the calibration of complex material constitutive models in the mixed-effects framework.
Les processus de démantèlement des volcans, le cas d'un volcan bouclier en milieu océanique : le Piton des Neiges, Île de la Réunion

Le Piton des Neiges, volcan inactif depuis 12. 000 ans, se caracterise par un massif fortement demantele et par la presence au fond de trois grandes depressions appelees " cirque ", d'une importante couverture brechiques. La reinterpretation recente des breches implique une reevaluation du modele d'evolution geologique du volcan. Les investigations de terrain ont permis d'etablir une typologie des breches basee sur des caracteristiques sedimentaires et morphologiques. Plusieurs destabilisations de flanc de grande ampleur de type avalanche de debris (volume >> 1 km3) ainsi que de nombreux phenomenes gravitaires d'ampleur plus moderee lies, en autre, aux processus d'erosion, ont ete identifies. Au moins trois grandes destabilisations de flanc ont ete identifiees dans les cirques de Cilaos et de Salazie. Les depots brechiques lies a ces destabilisations ont ete ensuite progressivement recouverts par des coulees de debris et des alluvions diverses puis erodes. Aujourd'hui, il apparait clairement que ces breches sont en partie les temoins de grands processus de demantelement lies a plusieurs destabilisations massives de l'edifice volcanique
Clinical and laboratory features of biliary atresia and patterns of management practices: Saudi national study (2000–2018)

Background: We utilized the data from the Saudi national biliary atresia (BA) study (2000–2018) to describe the clinical, biochemical, imaging, and histopathological features of BA and the perioperative clinical practices among local pediatric gastroenterologists. Methods: This is a retrospective, multicenter, nationwide study that included 10 tertiary care governmental hospitals including the four liver transplant (LT) centers in different regions across Saudi Arabia. Results: BA was diagnosed in 204 infants (106 females; 10% preterm). The median age at referral was 65 days. Congenital anomalies were present in 68 patients (33%); 22 were splenic malformation (10.8%). The medians of laboratory investigations were total bilirubin (189 μmol/l), direct bilirubin (139 μmol/l), ALT (164 u/l), and GGT (472 u/l). The level of serum GGT was normal in 26 cases (12.7%). The ultrasound findings included hypoplastic or atrophic gall bladder (GB) (65%), normal GB (30%), and cord sign (5%). A HIDA scan was performed in 99 cases (48.52%). Magnetic resonance cholangiopancreatography (MRCP) was performed in 27 cases (13%). A total of 179 liver biopsies (88%) were obtained. The most common histopathologic findings were bile duct proliferation (92%), canalicular cholestasis (96%), bile plugs (84%), and portal fibrosis (95%). Cholangiography was performed in 139 cases (68%): operative in 122 (60%) and percutaneous in 17 (8%). A total of 143 children (70%) underwent Kasai portoenterostomy (KPE) at a median age of 70 days. After KPE, steroid was used in 37% of the cases and 100 cases (70%) were prescribed prophylactic antibiotics for variable duration (ranging between 3 and 12 months). Conclusion: Our data show marked variation in the diagnostic evaluation and perioperative management of BA cases among the different tertiary centers. There is a need to establish a national BA registry in Saudi Arabia aiming to standardize pre- and postoperative clinical practices. Additionally, normal serum GGT level, normal GB size on ultrasound, and being a premature baby should not preclude the diagnostic workup for BA.

The research respondents were 144 teachers, the data were processed using the PLS Structural Equation Modeling (SEM). The study proposed supervisors' supervision as a strategy to improve teacher performance. The results of the study show that professionalism and creativity affect teacher performance—supervisors' supervision plays a role in strengthening teacher performance. These results strengthen the Human Capital Theory stating that a combination of knowledge, skills, innovation, and a person's ability to carry out their duties can create value to achieve goals.
Force-Controlled Biomechanical Simulation of Orthodontic Tooth Movement with Torque Archwires Using HOSEA (Hexapod for Orthodontic Simulation, Evaluation and Analysis)

This study aimed to investigate the dynamic behavior of different torque archwires for fixed orthodontic treatment using an automated, force-controlled biomechanical simulation system. A novel biomechanical simulation system (HOSEA) was used to simulate dynamic tooth movements and measure torque expression of four different archwire groups: 0.017″ x 0.025″ torque segmented archwires (TSA) with 30° torque bending, 0.018″ x 0.025″ TSA with 45° torque bending, 0.017″ x 0.025″ stainless steel (SS) archwires with 30° torque bending and 0.018″ x 0.025″ SS with 30° torque bending (n = 10/group) used with 0.022″ self-ligating brackets. The Kruskal–Wallis test was used for statistical analysis (p < 0.050). The 0.018″ x 0.025″ SS archwires produced the highest initial rotational torque moment (My) of −9.835 Nmm. The reduction in rotational moment per degree (My/Ry) was significantly lower for TSA compared to SS archwires (p < 0.001). TSA 0.018″ x 0.025″ was the only group in which all archwires induced a min. 10° rotation in the simulation. Collateral forces and moments, especially Fx, Fz and Mx, occurred during torque application. The measured forces and moments were within a suitable range for the application of palatal root torque to incisors for the 0.018″ x 0.025″ archwires. The 0.018″ x 0.025″ TSA reliably achieved at least 10° incisal rotation without reactivation.
Efficacy of Ozonized Sunflower Oil with Tea Tree Oil as Desensitizing Agents in Dental Bleaching: Randomized and Double-Blind Clinical Trial

Background: Dental bleaching is one of the most commonly prescribed procedures in aesthetic dentistry due to its effectiveness and minimally invasive nature. However, a recurrent and challenging side effect is dentin hypersensitivity after the procedure. Aim: This study aimed to evaluate whether the use of ozonized oil combined with tea tree oil is effective in controlling post-bleaching dentin sensitivity. Methods: A randomized, double-blind, split-mouth clinical trial was conducted. Participants were divided into two experimental groups (n=29) according to the desensitization protocol: control group: potassium nitrate and sodium fluoride; test group: ozonized sunflower oil combined with tea tree oil. Both groups were applied before dental bleaching with 35% hydrogen peroxide. The obtained data were subjected to statistical analysis using a non-parametric Friedman repeated measures ANOVA test (p < 0.05), followed by the Durbin-Conover post hoc test (p < 0.05). Results: In the assessment of sensitivity level, there were no statistically significant differences between the test group and the control group. A higher level of sensitivity was observed for the lower arch after one hour of bleaching agent removal in both groups, and the color change was statistically equal between the two groups. Conclusion: The study concluded that the test group paste was as effective in reducing dental sensitivity caused by dental bleaching as the control group. Additionally, neither of the groups affected the bleaching capacity of hydrogen peroxide.
Workers’ Satisfaction during the COVID-19 Pandemic in Central and Eastern Europe

This article analyses the determinants of worker satisfaction in Central and Eastern European countries, focusing on the effects of the COVID-19 pandemic. For this purpose, the latest European Social Survey data were utilised in a multilevel framework, covering 5681 workers from eight countries. The results suggest that both the general stringency of policies aimed at containing the spread of the COVID-19 contagion and the resulting disruptions to individuals’ working lives significantly affected the well-being of workers. Workers’ satisfaction with their jobs was negatively affected mainly through decreases in work income, but the impact on their overall life satisfaction was more complex. While income reductions and workplace relocation negatively impacted life satisfaction, the opportunity and possible necessity to stay home more positively affected the life satisfaction of workers. Nevertheless, the overall stringency of governmental policies related to COVID-19 significantly reduced workers’ life satisfaction.
