Effect of arbuscular mycorrhizal fungi on rhizosphere organic acid content and microbial activity of trifoliate orange under different low P conditions

ABSTRACT Arbuscular mycorrhizal (AM) fungi can improve plant phosphorus (P) uptake; however, information about how AM fungi affect rhizosphere organic acid and microbial activity to alleviate citrus low P stress is limited. Here, a pot experiment was conducted to evaluate the effect of AM fungi (Rhizophagus intraradices, Ri) inoculation on rhizosphere organic acid content, microbial biomass (MB) and enzyme activity of trifoliate orange (Poncirus trifoliata L. Raf.) seedlings grown under three low P conditions. The results showed that mycorrhizal seedlings all recorded higher P concentrations, plant biomass and better root morphology with more lateral and fine roots, but lower root mass ratios, irrespective of P conditions. Mycorrhizal P absorption contribution did not differ significantly among three P conditions. Mycorrhizal seedling rhizosphere soil exhibited lower organic acid content, soil organic P content and ratio of MB-carbon (C)/MB-P, but higher MB and enzyme activity. Additionally, the main organic acids showed a negative relationship with mycorrhizal colonization rate and hyphal length; however, phosphatase and phytase activity had a significantly positive relationship with MB. Therefore, the results suggest that AM fungi inoculation may help citrus to efficiently utilize organic P source by improving microbial activity under low available P conditions.

Ecological consequences of Great Lakes salmon subsidies for stream-resident brook and brown trout

Introduced Pacific salmon (Oncorhynchus spp.) deliver novel, pulsed resource subsidies to Great Lakes streams. We explored interactions between native brook trout (Salvelinus fontinalis) and non-native brown trout (Salmo trutta) in the context of this resource pulse. Diets surveyed before and during salmon spawning showed that, regardless of species, trout consumed 4.5-fold more biomass during than before salmon runs. Brook trout grew more quickly than brown trout under controlled feeding regimes due, in part, to their higher food conversion efficiency of 36% compared with 21%. Bioenergetics model simulations explored the influence of temperature on the exploitation of resource pulses and found 35% lower growth rates and increased gorging at colder temperatures. Overall, we found evidence that brook trout and brown trout foraging and growth are modulated by the salmon resource pulse, especially through gorging on eggs. However, these species exhibit distinct physiological adaptations and environmental preferences that may influence their ultimate capacity to exploit resource pulses. The effects of environmental conditions and salmon subsidies on stream-resident trout have broader consequences for fisheries management and conservation efforts.
Three solutions for a new Kirchhoff-type problem

This article concerns on the existence of multiple solutions for a Kirchhoff-type prob- lem with positive and negative modulus. By applying the variational methods and algebraic analysis, we prove that there exist the only three solutions when the parameter is absolutely small than a constant, only two solutions when the parameter is absolutely equals with the constant and an unique solution when the parameter is absolutely greater than the constant. Moreover, we use the algebraic analysis to calculating the constant with the help of one of the Mountain Pass Lemma, Ekeland variational principle, and Minimax principle.
Reflexible complete regular dessins and antibalanced skew morphisms of cyclic groups

A skew morphism of a finite group A is a bijection φ on A fixing the identity element of A and for which there exists an integer-valued function π on A such that φ(ab) = φ(a)φ(b), for all a, b ∈ A. In addition, if φ−1(a) = φ(a−1)−1, for all a ∈ A, then φ is called antibalanced. In this paper we develop a general theory of antibalanced skew morphisms and establish a one-to-one correspondence between reciprocal pairs of antibalanced skew morphisms of the cyclic additive groups and isomorphism classes of reflexible regular dessins with complete bipartite underlying graphs. As an application, reflexible complete regular dessins are classified.
Performance of a PDE-Based Hydrologic Model in a Flash Flood Modeling Framework in Sparsely-Gauged Catchments

Modeling and nowcasting of flash floods remains challenging, mainly due to uncertainty of high-resolution spatial and temporal precipitation estimates, missing discharge observations of affected catchments and limitations of commonly used hydrologic models. In this study, we present a framework for flash flood hind- and nowcasting using the partial differential equation (PDE)-based ParFlow hydrologic model forced with quantitative radar precipitation estimates and nowcasts for a small 18.5 km2 headwater catchment in Germany. In the framework, an uncalibrated probabilistic modeling approach is applied. It accounts for model input uncertainty by forcing the model with precipitation inputs from different sources, and accounts for model parameter uncertainty by perturbing two spatially uniform soil hydraulic parameters. Thus, sources of uncertainty are propagated through the model and represented in the results. To demonstrate the advantages of the proposed framework, a commonly used conceptual model was applied over the same catchment for comparison. Results show the framework to be robust, with the uncalibrated PDE-based model matching streamflow observations reasonably. The model lead time was further improved when forced with precipitation nowcasts. This study successfully demonstrates a parsimonious application of the PDE-based ParFlow model in a flash flood hindcasting and nowcasting framework, which is of interest in applications to poorly or ungauged watersheds.
Full Range Capacitor Voltage Balance PWM Strategy for Diode-Clamped Multilevel Inverter

This paper briefly reviews virtual space vector pulse width modulation (VSVPWM) for the diode-clamped multilevel inverter (DCMLI). Based on the universal modulation model of the DCMLI with N-level, a modulation strategy named as full range capacitor voltage balance PWM (FRCVBPWM) is proposed, which has similar capacitor voltage balance characteristics as VSVPWM. The characteristic of FRCVBPWM is that there are respectively zero, N − 1 and N − 2 switching actions for the three phases of the DCMLI. Therefore, the total switching actions are greatly decreased compared with VSVPWM. The switching loss comparison between FRCVBPWM and VSVPWM is conducted by comprehensive simulations. Finally, the feasibility and superiority of FRCVBPWM over VSVPWM is verified by experiments.
Determination of Non-Steroidal Anti-Inflammatory Drugs in Animal Urine Samples by Ultrasound Vortex-Assisted Dispersive Liquid–Liquid Microextraction and Gas Chromatography Coupled to Ion Trap-Mass Spectrometry

A low solvent consumption method for the determination of non-steroidal anti-inflammatory drugs (NSAIDs) in animal urine samples is studied. The NSAIDs were extracted with CH2Cl2 by the ultrasound vortex assisted dispersive liquid–liquid microextraction (USVA-DLLME) method from urine samples, previously treated with β-glucuronidase/acrylsulfatase. After centrifugation, the bottom phase of the chlorinated solvent was separated from the liquid matrix, dried with Na2SO4, and derivatized with N,O-bis(trimethylsilyl)trifluoroacetamide (BSTFA) + trimethylchlorosilane (TMCS) (99 + 1). After cooling at room temperature, the solution was concentrated under nitrogen flow, and 1 µL of solution was analyzed in gas chromatography/ion trap-mass spectrometry (GC-IT-MS). The enrichment factor was about 300–450 times and recoveries ranged from 94.1 to 101.2% with a relative standard deviation (RSD) of ≤4.1%. The USVA-DLLME process efficiency was not influenced by the characteristics of the real urine matrix; therefore, the analytical method characteristics were evaluated in the range 1–100 ng mL−1 (R2 ≥ 0.9950). The limits of detection (LODs) and limits of quantification (LOQs) were between 0.1 and 0.2 ng mL−1 with RSD ≤4.5% and between 4.1 and 4.7 ng mL−1 with RSD ≤3.5%, respectively, whereas inter- and intra-day precision was 3.8% and 4.5%, respectively. The proposed analytical method is reproducible, sensitive, and simple.
Ashkenazim and Mizrahim in the Israeli-Palestinian Peace Process: The Role of Israel’s Economic Liberalization and Globalization

ABSTRACT This paper examines the mechanisms which drive the different political attitudes of Israel’s two major Jewish groups – the Ashkenazim and the Mizrahim – vis-à-vis the Israeli-Palestinian peace process in the 1990s. The study argues that the economic liberalization reforms of the 1980s along with the subsequent Israel’s integration with the global economy are key drivers of the two groups’ opposing attitudes vis-à-vis the peace process. These processes benefited mainly the business classes, who are dominated by the Ashkenazim (originating from Europe). It was such benefit that drove Ashkenazim’s support for the Oslo Accords in the 1990s, which was seen as instrumental to the process of Israel’s integration with the global economy. Conversely, the same economic processes likely hurt lower-class members of Israeli Jewish society, most of whom are Mizrahim (originating from Muslim countries). In this context the settlements in the West Bank and Gaza provided them with an alternative source of welfare to buffer the negative impacts of the integration process. As a result most of the Mizrahim population opposed any peace deal that included the evacuation of settlements. Moreover, Mizrahim’s opposition to Oslo was strengthened by the association of Oslo with Israel’s global integration, which some evidence suggests mainly benefited the business classes.

Synthesis and Biological Activity Evaluation of Polyfunctionalized Anthraquinonehydrazones

Anthraquinone derivatives, frequently occurring motifs in many various natural compounds, have attracted a great deal of interest as compounds with a wide spectrum of biological activities. The hybrid pharmacophore approach has become an object of considerable interest due to the incorporation of a five- or six-membered heterocyclic rings in the structure of various natural compounds, especially anthraquinone derivatives. A series of polyfunctionalized anthraquinonehydrazones have been synthesized via the azo-coupling reaction between anthraquinone-based triazenes and methylene active compounds. The structures of synthesized compounds were confirmed by spectral data. Some of the synthesized compounds were screened for their in vitro anticancer activity according to US NCI protocols. The screening of antimicrobial and antifungal activities against Candida albicans and Lactobacillus sp. was carried out. The synthesized compounds were evaluated for their antioxidant (DPPH free radical scavenging assay) and herbicidal activity. The synthesized 1-[N'-(5-oxo-2-thioxoimidazolidin-4-ylidene)-hydrazino]-anthraquinone 1.5 displayed a high level of antimitotic activity against tested human tumor cells with mean GI50/TGI values 4.06/78. 52μM. The screening of antimicrobial and antifungal activities led to the identification of 1.8 and 1.9 with a moderate effect on Candida albicans and Lactobacillus sp. Antioxidant activity evaluation allowed the identification of 1-[N'-(3-methyl-5-oxo-1-phenyl-1,5- dihydropyrazol-4-ylidene)-hydrazino]-anthraquinone 1.8 with an IC50 value of 3.715 mM. The herbicidal activity screening led to compound identification 1.8 with growth inhibition of Agrostis stolonifera at 25 %. The obtained anthraquinonehydrazones constitute an interesting template for the design of new synthetic agents with polypharmacological activities.

Interactional Justice and Organizational Citizenship Behaviour of Academic Staff in Universities in Bayelsa State

DOI: http://dx.doi. org/10.24018/ejbmr.2020. 5.4. 418 Vol 5 | Issue 4 | July 2020 1 Abstract — This study was carried out to ascertain the effect of Interactional Justice on Organizational Citizenship Behaviour of Academic Staff in Universities in Bayelsa State. Cross Sectional Research design was adopted. A sample size of 294 was obtained from a population of 1,268 workers, using Krejcie and Morgan (1970) Sample size determination table. With the aid of Statistical Package for Social Sciences, the Spearman Rank Order Correlational Coefficient was used to analyse the data. The results obtained showed a significant positive relationship between Interactional Justice and all measures of Organizational Citizenship Behaviour (Altruism, Courtesy, Conscientiousness, Civic Virtue, and Sportsmanship), indicating that workers are very helpful and assist colleagues with problems. It was recommended that management should always be polite and respectful to employees and involve them in decision making because employees perception of equity breeds extra role behaviour.
Comparing traditional and Bayesian approaches to ecological meta‐analysis

Despite the wide application of meta‐analysis in ecology, some of the traditional methods used for meta‐analysis may not perform well given the type of data characteristic of ecological meta‐analyses. We reviewed published meta‐analyses on the ecological impacts of global climate change, evaluating the number of replicates used in the primary studies (ni) and the number of studies or records (k) that were aggregated to calculate a mean effect size. We used the results of the review in a simulation experiment to assess the performance of conventional frequentist and Bayesian meta‐analysis methods for estimating a mean effect size and its uncertainty interval. Our literature review showed that ni and k were highly variable, distributions were right‐skewed and were generally small (median ni = 5, median k = 44). Our simulations show that the choice of method for calculating uncertainty intervals was critical for obtaining appropriate coverage (close to the nominal value of 0.95). When k was low (<40), 95% coverage was achieved by a confidence interval (CI) based on the t distribution that uses an adjusted standard error (the Hartung–Knapp–Sidik–Jonkman, HKSJ), or by a Bayesian credible interval, whereas bootstrap or z distribution CIs had lower coverage. Despite the importance of the method to calculate the uncertainty interval, 39% of the meta‐analyses reviewed did not report the method used, and of the 61% that did, 94% used a potentially problematic method, which may be a consequence of software defaults. In general, for a simple random‐effects meta‐analysis, the performance of the best frequentist and Bayesian methods was similar for the same combinations of factors (k and mean replication), though the Bayesian approach had higher than nominal (>95%) coverage for the mean effect when k was very low (k < 15). Our literature review suggests that many meta‐analyses that used z distribution or bootstrapping CIs may have overestimated the statistical significance of their results when the number of studies was low; more appropriate methods need to be adopted in ecological meta‐analyses.
