description: The kinetics of the oxidation of fosfomycin disodium salt by cerium(IV) in an aqueous perchloric acid medium at constant ionic strength, I = 1.10 mol dm−3, has been investigated spectrophotometrically at 25 °C. The reaction is of first order in cerium(IV) concentration, fractional order in both fosfomycin and H+ ion concentrations. The active species of oxidant is found to be Ce(OH)3+. Based on the experimental results a suitable mechanism is proposed. The reaction constants involved in the different steps of the reaction mechanism and the activation parameters with respect to the slow step of the mechanism are determined and discussed.

description: The feasibility to produce compact Corylopsis sinensis var. calvescens and C. coreana plant in a 10 cm pot in one year from transplanting seedlings with maximized number of short shoots and inflorescences was investigated. Corylopsis sinensis var. calvescens was selected as a suitable species to produce compact plant with inflorescences. Slow release fertilizer (SRF) at a rate of 0, 0.125, 0.25, and 0.5 g per pot was applied to the surface of the growing medium (Expt. 1). Shoots were pinched 2 (Feb. 28), 4, 6, and 8 weeks (May 16) (Expt. 2) after transplanting, and ancymidol, paclobutrazol, chlormequat, and daminozide plant growth retardants were treated (Expt. 3). Application of a SRF at 0.5 g per pot and pinching four times at 2-week intervals before May 16 effectively increased the flowering percentages and the number of stems with inflorescences, to accelerate flowering, and also produced a compact plants. Paclobutrazol at 10-20 mg/L applied as soil drench was effective in inhibiting stem elongation in the first year; however, higher concentrations should be avoided to prevent excessive reduction in the growth of shoots and production of malformed inflorescences.

description: Plant-mediated nanoparticles synthesis is considered as one of the appealing options in bio-nanoparticles synthesis, however, there is contradictory information about the positive or negative impacts of nanoparticles on plants. Investigating the toxic effects of Ag NPs on model plants, such as onion, can reveal the probability of damage. Thus, the present study was conducted to compare the germination indices and biochemical parameters of edible onion seeds treated with different concentrations of two types of silver nanoparticles (green synthesized and chemical synthesized) to examine the oxidative stress. Based on our results, the interaction between leaf extract and silver salt resulted in a color change from pale yellow to dark brown, the first sign of the AgNPs formation. The green AgNPs treatment improved the onion germination indices. The green AgNPs-exposed seeds displayed a no-significant reduction in protein content and same protease activity as the control treatment, but chemical AgNPs-treated displayed a significant rise of protease and reduction in protein content in concentration more than 0.06 gL-1. In chemical AgNPs-treated seeds both peroxidase and catalase displayed an ascending linear trend and the most activities belonged to chemical AgNPs at 0.05 g L-1 (315.62 and 51.45 μmol min-1g-1 FW, respectively). Both nanoparticle types made an increase in MDA, but green AgNPs did not significantly differ with control treatment. It can be concluded that the green synthesis of nanoparticles is a safe and suitable alternative for chemical-synthesized metal nanoparticles.

description: The aim of this study was to determine the effect of different concentrations of sodium nitroprusside (SNP) on in vitro shoot organogenesis from hypocotyl explant derived from in vitro grown seedling as well as root formation of Antirrhinum majus L. (Snapdragon). In the first experiment, different concentrations of 2,4-dichlorophenoxyacetic acid (2,4-D) (0, 2.26, 4.52, and 6.79 μM) were used for callus formation. The highest callus fresh weight (1.86 g) as well as callogenesis frequency (93.34%) were observed in Murashige and Skoog (MS) medium containing 4.52 μM 2,4-D. In the later experiments, various concentrations (0, 10, 20, 30, 40, and 50 μM) of sodium nitroprusside (SNP) were applied for shoot regeneration from callus that derived from hypocotyl segments. Based on our results, MS medium supplemented with 4.44 μM 6-benzylaminopurine (BAP) plus 0.49 μM 3-indolebutyric acid (IBA) along with 30 μM SNP had the highest shoot organogenesis frequency (93.34%) and shoot number (6.33) from callus. In root induction experiment, different concentrations (0, 20, 40, 60, 80, and 100 μM) of SNP were applied and MS medium containing 60 μM SNP was the best treatment for root induction. The survival rate of plantlets was more than 95% in acclimatization stage. The present study describes an efficient regeneration system for Snapdragon.

description: This thesis is focused on the investigation of new procedures for the activation of alcohols towards dehydrative nucleophilic substitution reaction that release water as the sole by- product using commercially available arylboronic acids as catalysts. First, in Chapter I, the concept and background of dehydrative nucleophilic substitution reactions using Lewis or Brønsted acid catalysis is detailed. The use of boron-based catalyst for the activation of alcohols towards different reactions is described, with the intention of placing the work of this thesis in the context of the literature. In Chapter II, the development of a new system for the catalytic activation of benzylic alcohols towards dehydrative substitution using a second alcohol as the nucleophile is described. A commercially available arylboronic acid catalyst in combination with oxalic acid as a ligand can be used for the synthesis of symmetrical, cyclic, and unsymmetrical ethers. Mechanistic control experiments have identified a possible active catalytic species in the reaction media and a plausible reaction mechanism is discussed. Chapter III focuses on the application of the newly developed catalyst system for the dehydrative substitution of benzylic alcohols using carbon-based nucleophiles. The procedure has been demonstrated for a range of C-C bond forming reactions using either 1,3-diketone derivatives or allyltrimethylsilane as the nucleophile. Finally, in Chapter IV, a new protocol for the dehydrative Nazarov electrocyclization of allylic alcohols to form substituted furans is investigated. The optimised procedure uses a readily available arylboronic acid catalyst under mild conditions to promote the dehydrative cyclisation. Preliminary control experiments detailing the preparation of the possible active catalytic species are also described.

description: The new, monotypic camaenid genus Setocallosa is described for the new species S. pathutchingsae from Arnhem Land, Top End of the Northern Territory. This camaenid is characterized by a combination of distinct morphological features, such as a small, weakly elevated shell with widely open umbilicus and thick callus on the parietal wall, a wide epiphallic flagellum, elongated penis and short bursa copulatrix with subglobose end. The relationships of Setocallosa with the other camaenid genera in the area are investigated by means of mtDNA, but its phylogenetic position remains ambiguous. S. pathutchingsae occurs in sympatry with Arnhemtrachia ramingining, but based on morphology the two camaenids can be readily differentiated.http://zoobank.org/urn:lsid:zoobank.org:pub:1C50CF24-7FEE-446A-9724-A0A4E850B5AA

description: Zelkovaphis caucasica is a little-known Caucasian species of leaf-rolling aphids on Zelkova carpinifolia, and was not included in a previous morphological phylogenetic analysis of the tribe Eriosomatini. We redescribe little-known emigrants of Z. caucasica and describe first instars borne by the emigrants, with keys to species for these morphs of the genus Zelkovaphis. Based on the present specimens and a previously published description, we added Z. caucasica to a published data matrix for Eriosomatini species, and re-analysed the phylogenetic relationships of the tribe Eriosomatini. Successive weighting analysis indicated that Z. caucasica branched off at the base of the Eriosomatini phylogeny, as well as other leaf-rolling species on Zelkova. It is therefore suggested that, like other leaf rollers on Zelkova, Z. caucasica is a relict that has survived in glacial refugia.

description: Introduction: In healthcare, stories are an evocative way to educate nurses about the emotional experiences of patients. Little is known however, about the impact of storytelling in neonatal nursing practice and education. Aims: The aims were; to explore how parents of premature babies described their neonatal care experience; to develop digital stories informed by their narratives and to investigate how these may contribute to empathic learning in nursing students/staff. Methods: Within an interpretive, narrative design using principles from constructivism, twenty narrative interviews with parents of premature babies were undertaken to collect their stories. Core story creation reconfigured the raw narratives to develop digital stories using the ASPIRE model. Thematic and metaphor analysis were also applied. Finally, a mixed methods approach investigated the perceived value of the stories for empathic learning with nursing students and staff in neonatal care. Findings: Parents described their experience using a strong emotional narrative revealing important learning points for those caring for them. The use of metaphors was a common way to express emotion. Frequent metaphor clusters provided pivotal themes for the creation of digital stories. Four key themes emerged from the analysis: namely, the effect of digital stories on emotion and empathy, the perceived value of digital stories for learning and knowledge acquisition, the potential impact of digital stories on practice and the format of digital stories for representing emotion and evoking empathy. Overall, student nurses and staff evaluated the digital stories positively. It was clear that they were an effective way to teach others about emotional experiences of parents and had the potential to enhance empathy. Many participants indicated that stories may influence their practice by enhancing understanding of the emotional needs of parents. Discussion: Digital stories appear to be an effective and evocative way of telling the stories of others and depicting their emotional experience from which we can learn. Emotions can be a source of knowledge, and digital stories representing the parents’ experience and emotions may enrich empathic learning. Conclusion: Value is placed on parent stories by students and staff in relation to enhancing empathic learning within the neonatal field. Digital stories can be one way of teaching emotional aspects of care that places the parents at the centre.

description: Across the United States, there are significant efforts to encourage university students to vote. University of Michigan, for example, has created UMICH Votes to increase student voter turnout. These efforts are succeeding—student voting rose from 52% in the 2016 presidential election to 66% in 2020. However, students in STEM fields consistently vote at lower rates than their counterparts. To help address this deficit, students involved with University of Michigan’s Science, Technology, and Public Policy (STPP) Program at the Gerald R. Ford School of Public Policy, have summarized the two main presidential candidates’ positions on issues likely to be of interest to STEM students: scientific research funding, technology policy, immigration policy, energy policy, environmental policy, and environmental justice policy.

description: Ethyl orange (EO) is a mono-azo dye, which is chiefly used as a dye in textile, food, and cosmetic industries. Removal of this dye from wastewater generated by these industries is a main concern in wastewater treatment. Hence, there is a need for a simple and inexpensive method to abolish this dye present in wastewater. A search through literature revealed that very few reports are available on the decolorization of EO dye and also no kinetic and mechanistic studies have been carried out about this dye. Consequently, an attempt is made to develop an oxidative decolorization method for EO dye with chloramine-T (CAT). The present study also aims to investigate the kinetics and mechanism of oxidative decolorization of EO dye with CAT in HClO4 medium spectrophotometrically (λmax = 474 nm) at 303 K. The reaction exhibits a first-order dependence of rate on [EO]o and fractional-order dependence, each on [CAT]o and [H+], respectively. The dielectric effect is positive. Activation parameters have been deduced. Oxidation products were identified as N-(4-diethylamino-phenyl)-hydroxyamine and 4-nitroso-benzenesulfonic acid. Suitable mechanism and related rate law have been worked out. Importantly, the present decolorization method is definitely an advantageous alternative technique in treating the EO dye present in wastewater.

description: Polychlorinated dibenzo-p-dioxins, polychlorinated dibenzofurans, and mono- and non-ortho polychlorinated biphenyls (dioxin-like PCBs) are identified as a family or group of organic compounds known as ‘dioxins’ or dioxin-like chemicals (DLCs). The most toxic member of this group is 2,3,7,8-tetrachlorodibenzo-(p)-dioxin (TCDD). Historically, DLCs have caused a variety of negative human health effects, but a disfiguring skin condition known as chloracne is the only health effect reported consistently. As part of translational research to make computerized models accessible to health risk assessors, the Concentration- and Age-Dependent Model (CADM) for TCDD was recoded in the Berkeley Madonna simulation language. The US Agency for Toxic Substances and Disease Registry’s computational toxicology laboratory used the recoded model to predict TCDD tissue concentrations at different exposure levels. The model simulations successfully reproduced the National Health and Nutrition Examination Survey (NHANES) 2001–2002 TCDD data in age groups from 6 to 60 years and older, as well as in other human datasets. The model also enabled the estimation of lipid-normalized serum TCDD concentrations in breastfed infants. The model performed best for low background exposures over time compared with a high acute poisoning case that could due to the large dose and associated liver toxicity. Hence, this model may be useful for interpreting human biomonitoring data as a part of an overall DLC risk assessment.

description: The synthesis of novel stationary phases for the HPLC group-type separation of several classes of nitrogen containing aromatic compound (NCAC) is described. They allow a molecular sorting of NCACs according to the type of nitrogen functionality. A coal tar pitch was chosen as a complex real-world sample. The NCACs were preconcentrated on neutral alumina followed by a group separation on a hafnium(IV) modified silica into four subfractions containing: (1) the nitrogen-free polycyclic aromatic compounds (PAC); (2) the neutral polycyclic aromatic nitrogen heterocycles (PANH) together with the nitriles, (3) the aminosubstituted PACs; and (4) the basic PANHs. Each compound group was eluted after a stepwise change of the solvent composition. All fractions were analyzed by GC-MS and a large number of NCACs were identified. The separations are necessary since many compounds are isomeric with compounds containing other functional groups so that MS methods do not suffice to identify the chemical class. The preseparation involves the removal of matrix components and a preconcentration of analytes of low concentration, thus enabling their analysis in complex mixtures.A separation of the (isomeric) neutral PANHs and the nitriles on a nickel(II)-containing metal organic framework (MOF) is also described, thus presenting a simple possibility to analyze nitriles without interference from other constituents of the sample.

The Imaginary and the Pandemic

description: Fear is built with real and imaginary components, but in the end all fear is an individual and social symbolic construction. The link with the real-objective is never only real, our link is always ideal, in the sense that it is a cultural construction that we make and with which we read and reconstruct what comes to us from reality and this can be called representation (Weber; Durkhein) or ideology (Althusser). This construction is the social representation of reality that we make ourselves and with which we read the real (Moscovici). The representation of fear is social on the one hand because it is collective, that is, it arises between individuals and has in the end, the individuals themselves as a destination, but does not correspond to one or the other, but is common to a specific society. And, in a more relevant way, it is social because it is the product of the interaction of different actors, that is, it is not created or lived by a single actor, but a multiplicity of actors that in their exchanges of information pregnant with prejudices and deformations, create a result, a notion, which guides the behaviour of individuals.

description: Photoselective netting is a new group of colored netting developing in the past few decades. The effect of colored (red, green, and yellow) netting was studied on physiological traits of Codiaeum and Aglaonema in a trial in Flowers and Ornamental Plants Research Station of Lahijan, north of Iran. The trial was based on a split-plot experiment with two factors. The first factor was devoted to colored netting at four levels (no netting, green, yellow, and red) and the second factor was devoted to plant species at two levels of Codiaeum and Aglaonema based on a randomized complete block design with three replications. The results showed the positive effect of yellow netting on improving the vegetative capability of the plants, so that the highest plant height, shoot and root fresh and dry weight, and leaf area were observed in the plants grown under the yellow netting. Also, the highest anthocyanin, carotenoid contents, and catalase activity were obtained from the red netting and the highest Brix° and total chlorophyll from the red and yellow netting. According to the results, the highest vegetative growth rate was related to Codiaeum. The application of the colored nets provided the plants with more optimal growth conditions.

description: The variability affecting the main agronomic traits of 10 snake melon genotypes (Cucumis melo var. flexuosus L.) (three F1 hybrids, six breeding lines and the widely grown and consumed traditional cultivar Mornagui), grown under greenhouse conditions during 2014 and 2015 seasons, was examined and compared. Their resistance to powdery mildew was also checked. The main production-driving agronomic traits varied significantly (P<0.05) depending on the genotype. The major skin colour determined visually was different among the considered genotypes. The hybrids (H5 and H12) and the breeding lines (L1, L2, L5, L6 and L9) had dark green skin. The fruits of the hybrid H7 were dark and light green and the breeding line L4 has intense and dark green fruits whereas cv. Mornagui was characterized by medium light green fruits. Regarding fruit shape, the hybrids H7 and H5 produced straight fruits whereas the hybrid H12 and the breeding lines; L2, L4, L5, and L9 and the cv Mornagui had elongate fruits. However both breeding lines L1 and L6 were characterized by straight elongate fruits. The F1 hybrid H5 was the most productive (3.6 Kg/plant and ≈ 21 fruits/plant for total yield and number of fruit/plant respectively). These findings are useful for further breeding programs aiming to develop new powdery mildew resistant snake melon cultivars with satisfying agronomic traits.

description: The paper examined the effect of VAT on economic growth in Nigeria between 1994 and 2020 using consumer price index (CPI) as a threshold. A technique of Threshold Vector Autoregressive (TVAR) was employed and the results reveal that a VAT above the 10 percent threshold value endangers the economy while a VAT below the 7.59 percent threshold value does not harm the economy; rather, it improves people's well-being. It is therefore recommended that Nigerian economy should maintain the lower VAT threshold to cushion the effect of ever rising CPI on the citizens.

description: Large-scale propagation of Pyrus communis, which is a difficult-to-root species, is dependent on tissue culture technique. However, internal bacterial contaminations are an obstacle in tissue culture of fruit tree species. For this purpose, this investigation was conducted with several experiments to manage bacterial contamination. First, gram test for bacterial contamination related to Pyrus shoots proliferating was conducted. Gram test revealed that bacteria contaminating pear shoots were negative gram. Then, we investigated the application of cefixime (0, 100, 300 and 500 mg L-1) or ampicillin (0, 100, 300 and 500 mg L-1) for managing bacterial contaminations. It was found that the contaminated area on medium containing 500 mg L-1 cefixime (63.585 mm2) was lower than other treatments (803.84 mm2). Therefore, cefixime at 500 mg L-1 was selected to control the bacterial contamination. Next, different procedures were used included shaking with (1: sterile distilled water, 2: 500 mg L-1 cefixime and culturing in media with 500 mg L-1 cefixime, 3: 500 mg L-1 cefixime, culturing and subculturing in media with 500 mg L-1 cefixime 4: Disinfection). The third procedure was known the best due to the low bacterial contamination percentage and rate also the healthy growth of plants. Finally, the effect of gibberellic acid at 0 and 1 mg L-1 was investigated to compensate for shoot growth reducing in the presence of cefixime. 1 mg L-1 gibberellic acid improved the growth indices in the presence of cefixime

description: In response to the Sustainable Development Goals (SDGs) adopted by United Nations, combining using straw mulching, the proper crop planting date, and regulated deficit irrigation (RDI) is fundamental to adapt to climate change and to promote sustainable agriculture in the dry Mediterranean region. Two-year pot experiment under field conditions (2017 and 2018) was conducted in Damascus Countryside, Syria (altitude 600 m), to evaluate the onion crop response to early planting, irrigation level, and straw mulching. Treatments composed of three different planting dates with 28-day intervals (two early dates in February and March, and the traditional date in April), three irrigation levels (100, 80, and 60% of crop evapotranspiration, ETc), and two types of soil cover (with and without wheat straw mulch), with three replicates. Findings revealed that the seasonal ETc decreased from about 900 mm under current practice (planting in April without mulch) to only about 550 mm under both straw mulch and earliness in planting. Large bulb yield increases (more than double) were also obtained. Moreover, early planting using straw mulching significantly enhanced the onion crop response to RDI, even at 60% of ETc. Combining early planting in February, straw mulching, and full irrigation represents the best agricultural management.

description: Polychlorinated dibenzo-p-dioxins, polychlorinated dibenzofurans, and mono- and non-ortho polychlorinated biphenyls (dioxin-like PCBs) are identified as a family or group of organic compounds known as ‘dioxins’ or dioxin-like chemicals (DLCs). The most toxic member of this group is 2,3,7,8-tetrachlorodibenzo-(p)-dioxin (TCDD). Historically, DLCs have caused a variety of negative human health effects, but a disfiguring skin condition known as chloracne is the only health effect reported consistently. As part of translational research to make computerized models accessible to health risk assessors, the Concentration- and Age-Dependent Model (CADM) for TCDD was recoded in the Berkeley Madonna simulation language. The US Agency for Toxic Substances and Disease Registry’s computational toxicology laboratory used the recoded model to predict TCDD tissue concentrations at different exposure levels. The model simulations successfully reproduced the National Health and Nutrition Examination Survey (NHANES) 2001–2002 TCDD data in age groups from 6 to 60 years and older, as well as in other human datasets. The model also enabled the estimation of lipid-normalized serum TCDD concentrations in breastfed infants. The model performed best for low background exposures over time compared with a high acute poisoning case that could due to the large dose and associated liver toxicity. Hence, this model may be useful for interpreting human biomonitoring data as a part of an overall DLC risk assessment.
