Essential oil Composition, Antimicrobial Activity and Anatomical Characteristics of Foeniculum vulgare Mill. Fruits from Different Regions of Iran

Abstract The fruit essential oils of 23 Iranian and European sweet fennel (Foeniculum vulgare Mill.) samples were investigated for essential oil yield and chemical composition. The essential oil yield varied between 2.4% and 6.4%. The content of trans-anethole was from 85.07% to 90.38%. Other constituents: fenchone, estragole, 1,8-cineole and limonene were also present in higher amount than other constituents. Some anatomical characteristics were also evaluated. There was a negative correlation between trans-anethole content and thickness of epidermal anticlinal walls. Antibacterial activity against Escherichia coli, Salmonella typhimurium, Bacillus subtilis, and Staphylococcus aureus was also assessed. Among these bacteria, E. coli was the most sensitive, for which the MIC (minimal inhibitory concentration) and MBC (minimal bactericidal concentration) was 31.5 μg/ml and 62.5 μg/ml, respectively. The antibacterial effect was positively correlated with higher trans-anethole content.
The influence of pH on the growth-linked biodegradation kinetics of selected resin acids found in pulp mill effluent

Resin acids are hydrophobic diterpene carboxylic organic acids that change in solubility with dissociation as a function of pH. Due to the importance of resin acids as pulp mill effluent toxicants and the contradictory literature data surrounding the influence of pH on biodegradation, batch growth experiments were performed to determine whether changes in resin acid solubility, controlled by pH, could directly alter the kinetics of biodegradation. The results indicated that, while there were significant changes in solubility in the pH range of 6 to 8, removal kinetics with well-acclimated enrichment cultures did not vary appreciably, but a local maximum under alkaline conditions was noted. Above pH 8, decreases in microbial growth yield and growth rate were observed, and were thought to be due to stress associated with elevated pH. Below pH 2, a significant residual resin acid concentration, remained an the end of the exponential (balanced) growth phase. This residuum was essentially colloidal and was significant with respect to resin acid aquatic toxicity. Microbial membrane farty acids were found to be a promising sensitive measure for changes in biomass during controlled batch growth experiments on the biological removal of trace organic contaminants. Application : the extent and rate of contaminant removal are critical aspects of waste water treatment when considering the risks of discharge of acutely or chronically toxic effluent. This paper addresses the influence of pH on the extent and rate of resin acid removal.
Economic policy uncertainty, consumer confidence in major economies and outbound tourism to African countries

Uncertainty, which is the only certain thing about the future, influences economic agents, their behaviours and economic activity. Debates and concerns about policy uncertainty have intensified following events such as the financial crisis, Brexit and more recently, the Covid-19 pandemic. The purpose of this study is to investigate the impact of changes in economic policy uncertainty and consumer confidence in a set of major economies on tourism flows to African countries. Using data over the period of 2005–2019 and applying panel difference generalized method of moments method, our results show that a positive change in consumer confidence in Canada, China, France, Japan, Russia and the United Kingdom (UK) has favorable impact on tourism departures from these countries to 25 African countries. We also find that a positive change in uncertainty in Canada, Russia, Spain and the UK has negative effect on tourist departures from these countries to African countries. The implications of the results for tourism development in African countries are discussed.
Case Study of Using Ruqyah Complementary Therapy on a British Muslim Patient with Cluster Headache

A case study of a male British Muslim of Pakistani descend with severe cluster headache was presented. The patient only responded to morphine treatment but his condition continued to deteriorate. He resorted to ruqyah complementary therapy, which is based on incantations of the Quran, after seeking advice with a local imam (Islamic cleric). His condition improved significantly and continued to have weekly preventative ruqyah therapy. Since resorting to ruqyah, he has not any morphine treatment and the level and duration of pain have reduced significantly. Ruqyah is popular for the treatment of jinn possession but has also been found to have therapeutic effect on non-mental health problems. The case illustrates that complementing mainstream medicine with ruqyah can bring many benefits especially within the Muslim community. Cooperation between mainstream health service and faith healers is needed.
The Role of Nisin, Monolaurin, and EDTA in Antibacterial Effect of Rosmarinus Officinalis L. and Cinnamomum Zeylanicum Blume Essential Oils on Foodborne Pathogens

Abstract In this study, the role of nisin, monolaurin and EDTA in strengthening antibacterial effect of the Rosmarinus officinalis L. and Cinnamomum zeylanicum Blume essential oils were tested against foodborne pathogens including Escherichia coli, Salmonella typhimurium, Listeria monocytogenes and Staphylococcus aureus. The essential oils extracted by hydrodistillation and analyzed by gas chromatography-mass spectrometry (CG-MS). For determining antimicrobial effects of the essential oils in corporation with nisin, monolaurin and EDTA, agar disk diffusion and broth micro dilution susceptibility tests were used. According to GC-MS analyses, 15 and 14 components were identified for rosemary and cinnamon essential oils that representing 95.1 % and 94.25 % of total components, respectively. In the case of rosemary essential oil, 1,8-cineole (24.3 %), α-pinene (22.8 %), and camphor (12.1 %) were determined as the main volatiles. On the other hand, cinnamaldehyde (79.74 %) was determined as the major compound for cinnamon essential oil. According to antimicrobial activity tests, L. monocytogenes was found as the most sensitive microorganism. It is followed by S. aureus, E. coli, and S. typhimurium, respectively. In general, EDTA made the weakest effect on the MIC and MBC values of the essential oils. On the other hand, nisin made the most promising effect on the MIC and MBC values of the essential oils. In conclusion, using monolaurin, nisin and EDTA together with essential oils led to increases the antibacterial effect of essential oils against both Gram positive and Gram negative tested bacteria.
Kelvin–Helmholtz‐Related Turbulent Heating at Saturn's Magnetopause Boundary

One of the grand challenge problems of the giant planet magnetospheres is the issue of nonadiabatic plasma heating. Simple turbulent heating models consider the energy cascade rate from one scale to another where the energy density is based on perpendicular magnetic fluctuations of counterpropagating Alfvén waves. Analytical expressions from turbulence theory for the heating rate density have yielded promising results for the observed ion heating at Jupiter and Saturn. Here, we compare ion heating using hybrid simulations of the Kelvin–Helmholtz instability and analytical estimates in an effort to validate turbulence theory and further understand the nature of the ion heating. Heating rate densities ∼10−15 W/m3 are produced in our three‐dimensional Kelvin–Helmholtz simulations during the nonlinear growth phase and compare favorably with analytical estimates. Results targeting Saturn will be discussed in the broader context of radial plasma transport in the rapidly rotating magnetospheres.
Numerical study of ducted turbines in bi-directional tidal flows

ABSTRACT Installing a turbine in a duct generally increases the flow through the rotor. If there is flow confinement due to limited water depth, the presence of lateral boundaries, or the presence of adjacent turbines, a further flow enhancement through the rotor will be achieved. Extensive studies of ducted turbines in uni-directional flow have shown that rotor-based power coefficient can exceed the Betz-Joukowsky limit (BJL) for bare turbine, whereas the exceedance of the BJL is rarely reported for duct-area-based power coefficient . In this work, CFD studies have been carried out for several flanged duct turbines with different duct geometries under bi-directional flow conditions. The actuator disc approach is used to simulate the rotor. The results show that a flanged duct turbine with an inlet-arc flap and a curved brim can achieve a maximum value of close to the BJL for flow from either direction while a symmetric duct turbine- gives maximum of about 60% of the BJL. The effect of the flow confinement on shows increases with blockage ratio and a little variation in the relative performance of ducted and bare turbines. The findings pave the way for the realization of turbines with a flanged duct.
Stabilization for a class of delayed switched inertial neural networks via non-reduced order method

This paper tackles the issue of global stabilization for a class of delayed switched inertial neural networks (SINN). Distinct from the frequently employed reduced-order technique, this paper studies SINN directly through non-reduced order method. By constructing a novel Lyapunov functional and using Barbalat Lemma, sufficient conditions for the global asymptotic stabilization issue and global exponential stabilization issue of the considered SINN are established. Numerical simulations further confirm the feasibility of the main results. The comparative research shows that global stabilization results of this paper complement and improve some existing work.
Hydrothermally Reduced Graphene Hydrogel Intercalated with Divalent Ions for Dye Adsorption Studies

Fundamental studies involving divalent ion intercalated graphene-based hydrogel are still lacking in terms of their adsorption behavior towards dye pollutants. In this study, we prepared a self-assembled Mg2+ and Ca2+ intercalated reduced graphene hydrogel (rGH) using hydrothermal treatment to evaluate the intercalation impact on the adsorption capability towards cationic dyes, methylene blue and rhodamine B. The morphological, structural, thermal, and textural properties of the divalent ion intercalated reduced graphene hydrogels were studied using Fourier transform infrared spectrometer, thermogravimetric analysis, Raman spectroscopy, scanning electron microscope-energy dispersive spectroscopy, X-ray photoelectron spectroscopy, Brunauer–Emmett–Teller surface area analysis, and X-ray diffraction. The increased adsorption capacity of the divalent ion intercalated reduced graphene-based hydrogels towards the dye molecules resulted from the increase in the specific surface area and pore volume due to the Mg2+ and Ca2+ bridging that formed spaces between the graphene sheets framework. Adsorption kinetics and the equilibrium adsorption isotherm were fitted by a pseudo-second-order alongside intraparticle diffusion kinetic models and Langmuir isotherm respectively. In addition, the divalent ion intercalated reduced graphene hydrogel showed good generation after three cycles of simultaneous adsorption.
Towards Autonomous Operation by Advanced Process Control—Process Analytical Technology for Continuous Biologics Antibody Manufacturing

Continuous manufacturing opens up new operation windows with improved product quality in contrast to documented lot deviations in batch or fed-batch operations. A more sophisticated process control strategy is needed to adjust operation parameters and keep product quality constant during long-term operations. In the present study, the applicability of a combination of spectroscopic methods was evaluated to enable Advanced Process Control (APC) in continuous manufacturing by Process Analytical Technology (PAT). In upstream processing (USP) and aqueous two-phase extraction (ATPE), Raman-, Fourier-transformed infrared (FTIR), fluorescence- and ultraviolet/visible- (UV/Vis) spectroscopy have been successfully applied for titer and purity prediction. Raman spectroscopy was the most versatile and robust method in USP, ATPE, and precipitation and is therefore recommended as primary PAT. In later process stages, the combination of UV/Vis and fluorescence spectroscopy was able to overcome difficulties in titer and purity prediction induced by overlapping side component spectra. Based on the developed spectroscopic predictions, dynamic control of unit operations was demonstrated in sophisticated simulation studies. A PAT development workflow for holistic process development was proposed.
Application of Structured Robust Synthesis for Flexible Aircraft Flutter Suppression

This article presents a method for structured robust control design for systems with a mixture of parametric and dynamic uncertainty. The proposed method alternates between an analysis step and a synthesis step. Samples of the parametric uncertainty are computed during the analysis steps, thus yielding an array of uncertain systems containing only dynamic uncertainty. The controller is then synthesized on this array of uncertain models. This synthesis step itself involves an alternation between constructing a D-scale for each of the uncertain systems and tuning a single controller for the entire collection of scaled plants. The controller tuning is performed using structured control design techniques. The proposed method is utilized to design a flutter suppression controller for a flexible aircraft. The aircraft dynamics are described by both a high-fidelity and a reduced-order model. The design objectives for flutter suppression are to achieve robust stabilization in the presence of mixed uncertainty. The proposed structured design method yields a single, low-order, linear time-invariant (LTI) controller, which increases the flutter speed by 15%. Additional robustness analyses and high-fidelity simulations are provided to assess the controller performance.

Frontiers in Dentistry

Article type: Original Article Objectives: This study evaluated the effect of two educational interventions on knowledge and self-reported practice of mothers of 8-year-old children regarding emergency management of traumatic dental injuries (TDIs). Materials and Methods: Six public elementary schools (girls and boys) in Tehran were randomly selected. The mothers of 8-year-old students at each school were randomly assigned to three groups: intervention by poster, intervention by pamphlet, and control. An anonymous valid and reliable questionnaire, including demographics, previous experience on TDIs, mothers’ knowledge, and self-reported practice about emergency management of TDIs was provided to the mothers. After collecting the questionnaires, educational interventions by poster and pamphlet with similar contents regarding stepby-step emergency management of TDIs were performed for the target groups. Three months after the interventions, the same questionnaire was completed by the mothers. The results of pre-test and post-test were compared. Results: Totally, 201 mothers participated in this study. The mean knowledge score significantly increased in the pamphlet group (P<0.05) after the intervention, while this change was not significant in the poster and control groups (P>0.05). The mean knowledge score was significantly higher in the pamphlet than the poster group (P=0.009). The mean self-reported practice score significantly increased after the intervention in both intervention groups (P<0.05) but not in the control group. There was no significant difference in the mean self-reported practice score between the two intervention groups (P>0.05). Conclusion: Both pamphlet and poster were equally effective in improving the selfreported practice of mothers regarding TDIs, which highlights the significance of educating mothers.

Residents’ Attitude toward Tourism—Do the Benefits Outweigh the Downsides? The Case of Constanta, Romania

While the positive economic impact of tourism cannot be denied, it has also a number of negative side effects. The article focuses on the residents’ perception regarding the tourist activity and on identifying the factors influencing their acceptance for the tourist activity, in Constanta (Romania). A questionnaire based quantitative research was employed, creating several indexes, subsequently included in econometric models in order to reveal the factors which determine residents’ acceptance and support for tourism. The results reveal that residents are highly in favour of tourism activity and support tourism expansion and further development. Most respondents considered that tourism contributed to the improvement of the city image and identified a fairly positive economic impact, while tourism was accountable for the increase in several negative phenomena. The impact of tourist activity on the sustainable development of the city was perceived as medium positive, while most respondents considered that the number of tourists should increase. The residents’ acceptability toward tourism was revealed to depend on several variables and computed indexes: city development index, impact on residents’ quality of life index, sustainable development index, and perceived intensity of contact with tourists.
Does Customer Orientation Matter? Direct and Indirect Effects in a Service Quality-Sustainable Restaurant Satisfaction Framework in China

This study aims to further understand the moderating role of customer orientation in the formation of customer satisfaction in the Chinese restaurant context. The first finding of direct effects reveals that customer orientation has a positive impact on quality evaluations, restaurant image and customer satisfaction. Taken in sequence, customer orientation improves quality evaluations, which, in turn, improves restaurant image and customer satisfaction. In particular, restaurant image by itself is not significant in its impact on customer satisfaction, whereas higher levels of customer orientation moderate to strengthen the relationship of restaurant image with customer satisfaction. The authors then provide a managerial framework that can be used to guide customer orientation improvement efforts.
Mixed boundary value problems for Rayleigh wave in a half‐plane with cubic anisotropy

The paper deals with mixed boundary value problems in an elastic half‐plane with cubic symmetry. The formulation of the problem depends on an asymptotic model derived for anisotropic materials. It is demonstrated that defining the displacements in terms of a pair of plane harmonic functions reduces the problem to a classical isotropic form, which can be formulated within the framework of the asymptotic hyperbolic–elliptic model developed for isotropic materials. As an example, a semi‐infinite rigid stamp moving at a constant speed along the surface is considered.
Phenetic and Molecular Diversity of Nitrogen Fixating Plant Growth Promoting Azotobacter Isolated from Semiarid Regions of India

In the present study, 24 Azotobacter strains were isolated from soils of different areas of southern Rajasthan and characterized at biochemical, functional, and molecular levels. The isolated Azotobacter strains were gram negative and cyst forming when viewed under the microscope. These strains were also screened for their plant growth promoting activities and the ability of these isolates to survive under abiotic stress conditions viz. salt, pH, temperature, and drought stress. All the isolates showed IAA, siderophore, HCN, and ammonia production, whereas seven Azotobacter strains showed phosphate solubilization. Amplified Ribosomal DNA Restriction Analysis (ARDRA) revealed significant diversity among Azotobacter strains and the dendrogram obtained differentiated twenty-four of the strains into two major clusters at a similarity coefficient of 0.64. Qualitative and quantitative N2 fixation abilities of these strains were also detrained, and the amounts of acetylene reduced by Azotobacter strains were in the range of 1.31 to 846.56 nmol C2H4 mg protein−1 h−1. The strains showing high nitrogen fixation ability with multiple PGP activities were selected for further pot studies, and these Azotobacter strains significantly increased the various plant growth parameters of maize plantlets. Furthermore, the best Azotobacter isolates were subjected to 16S rRNA sequencing and confirmed their identities as Azotobacter sp. The indigenous Azotobacter strains with multiple PGP activities could be further used for commercial production.
Pre-Zanclean end of the Messinian Salinity Crisis: new evidence from central Mediterranean reference sections

The concept of a geologically instantaneous earliest Zanclean reflooding of the Mediterranean Basin after the Messinian drawdown has dominated geological thinking and is ingrained in the scientific literature. The base of the Trubi Formation in southern Italy, formally defined as the Zanclean Global Boundary Stratotype Section and Point (GSSP) at 5.33 Ma, has traditionally been considered as marking the marine reflooding of the Mediterranean. However, several studies provide evidence that marine reflooding occurred prior to the Zanclean GSSP, the most reliable of which comes from southern Calabria. Here, we show that the sedimentary coastal prism cropping out extensively immediately below the base of the Trubi Formation in this region and correlatable with the Arenazzolo Unit in Sicily contains a fully marine micropalaeontological association of calcareous nannofossils and dinoflagellate cysts, thus pointing to both a high sea-level and marine conditions before deposition of the Trubi Formation (i.e. in the latest Messinian).
