Title: The Cumulative Dose of AMF and GB is More Effective in The Amelioration of Cr(VI) Toxicity in Sorghum (Sorghum Bicolor L.) Than Individually

Industrial and anthropogenic activities are the major source of heavy metal toxicants in agricultural soils. Among, heavy metal toxicants, hexavalent chromium is the most toxic toxicant that negatively affects plant’s metabolic activities and yield. It reduces the plant growth and development by influencing the antioxidant defence system’s activities. In the present experiment, two different soil applied dozes of GB viz. 50 and 100mM, and AMF, both individually and in combination were tested for their capability to ameliorate Cr toxicity in sorghum. The promotive behaviour of these treatments for antioxidant defence system was analysed at vegetative (35 DAS) and grain filling stage (95 DAS) in three varieties of sorghum viz. SSG 59-3, HJ 513 (multi-cut) and HJ 541 (single-cut) under 2 and 4 ppm Cr toxicity. At the same time resultant effects of this behaviour on Cr accumulation, grain yield and indices of oxidative stress was also studied. In this experiment antioxidant defence system includes enzymes viz. SOD, APX, CAT, GR, POD and metabolites viz. glutathione, ascorbate, proline, β-carotene and indices of oxidative stress includes parameters viz. PPO, H2O2 and MDA. The results delineated that Cr accumulation and indices of oxidative stress were increased with increasing concentration of Cr stress in all the varieties at both growth stages. Chromium stress at high concentration (4 ppm), decreased the grain yield (71.69 %) as compared with control. Due to 4 ppm Cr stress, PPO activity, MDA and H2O2 accumulation increased significantly (72.29 %, 73.15 %, 79 % respectively, at 35 DAS and 70.36 %, 74.78 %, 79.83 % respectively, at 95 DAS). GB and AMF individually increased antioxidant activity but in combination, further significantly increased antioxidant defence system’s activity which in turn decreased indices of oxidative stress and reduced the Cr toxicity and increased grain yield of sorghum in all varieties at both the growth stages. However, treatment of 100mM GB with AMF was observed most significant in decreasing oxidative stress and improved antioxidant system’s activities and grain yield as compared with all other treatments at both growth stages in all the varieties. SSG 59-3 cultivar showed lowest chromium content (1.60 and 8.61 ppm), indices of oxidative stress and highest antioxidant system’s activity as compared to HJ 513 followed by HJ 541 variety, at 35 and 95 DAS respectively. Thus, among the varieties SSG 59-3 was found most tolerant as compared to HJ 513 followed by HJ 541 variety. These findings suggest that both GB and AMF, either individually or combined can play a positive role to reduce oxidative stress and increased yield attributes under Cr toxicity in sorghum.
Marrakesh Wastewater Purification Experiment Using Vascular Aquatic Plants Eichhornia crassipes and Lemna gibba

This work tests experimentally the capacities of water hyacinth ( Eichhornia crassipes ) and duckweed ( Lemna gibba ) to purify wastewater in Marrakesh. 1) Eichhornia crassipes was grown in continuous culture with a constant flow rate of 10 l.min. −1 Organic, bacterial and parasitical loads were examined to determine the efficiency of the system. The results show that water hyacinth is well suited to the climatic conditions of Marrakesh. Domestic sewage purification by water hyacinth leads to satisfactory efficiency during the summer with an 87% reduction in chemical oxygen demand (COD) and 95% reduction in total suspended solids (TSS). Bacterial load reduction expressed by control of faecal contamination bacteria achieved 2 log units for a short theoretical retention time (7 days). Moreover, this process reduced parasitic helminth eggs to undetectable levels. 2) Lemna gibba was grown in continuous culture with a constant flow rate of 3 1. day −1 . Only organic loads were examined. Three categories of influents were tested to determine the system efficiency. The results obtained show that Lemna gibba has the capacity to purify a low organic load (COD:305–530 mg.l −1 ). The average influent COD was reduced by 82%. During the summer period the average influent COD and TSS has been reduced by 61% and 82% respectively.
Effect of curing regime on the performance and microstructure characteristics of alkali-activated slag-fly ash blended concrete

Abstract The use of alkali-activated materials to produce concrete is a promising technology. However, information on the optimum curing regime required to maximize the performance of such concrete is lacking. This paper examines the fresh and hardened properties and microstructure characteristics of alkali-activated slag-fly ash blended concrete subjected to various curing regimes. Results showed that the optimum curing regime for alkali-activated blended concrete mixtures made with 0 and 25% fly ash was a combination of water and subsequent air curing, while that for mixes made with 50% fly ash was continuous water curing. Among these mixes, that incorporating 25% fly ash presented superior density, bulk resistivity, water absorption, compressive strength, and modulus of elasticity. Microstructure analysis revealed that the reaction products were an intermix of calcium aluminosilicate hydrate and sodium aluminosilicate hydrate. Analytical regression models were also developed to correlate the hardened properties of alkali-activated slag-fly ash blended concrete.

Ameloblastic fibro-odontoma in a child patient: case report and literature review

The ameloblastic fibro-odontoma (AFO) is a mixed odontogenic tumor, with characteristics of ameloblastic fibroma, presenting enamel and dentin, which occurs more frequently in individuals aged 5 to 17 years. This paper reports na extensive case of ameloblastic fibro-odontoma in the mandible of a 3-year-old patient, discussed in comparison to cases selected from a brief literature review on the clinical characteristics, Evolution and therapeutic options for this lesion. In the last years, there was no consensus in the literature concerning its etiopathogenesis and classification, yet recently the AFO was classified as a developing odontoma. This case is in accordance with the 7 cases reported in the literature of AFO in the mandible of children aged 10 years or younger, especially concerning the lesion pattern and evolution and treatment adopted. The patient did not present relapse and exhibited local bone regeneration at the 3-year follow-up.
The Quintuple Helix of Innovation Model and the SDGs: Latin-American Countries’ Case and Its Forgotten Effects

The sustainable development of countries is associated with a set of actions that must be implemented in the long term. In this process, society must be a valid partner in the decisions that are made. Studies show the interrelationship between the Sustainable Development Goals (SDGs), which increases uncertainty and makes decision-making more difficult. On the other hand, the Quintuple Helix of Innovation Model (QHIM) provides an analytical framework to explain the systems’ interactions. The motivation of the study lies in knowing the relationships between the variables that affect SDGs. The manuscript aims to broaden the discussion on sustainable development and propose two models to support decision making. The first one suggests 20 indicators linked to the QHIM with the SDGs in Latin American countries. The second identifies the forgotten effects through the application of a Fuzzy Logic algorithm. The main contribution is to know these effects and to support decision-making. The research carried out can be classified as applied, with the explanatory objective and the combined approach (quantitative-qualitative), modeling and simulation, and case study methods. The QHIM results indicate that Chile leads the ranking, followed by Brazil, Mexico, Peru, and Colombia. Also, it reveals the importance of correctly identifying cause-effects by seeking harmony between systems. A limitation would be the number of variables used. The study indicates promising lines of research.
Fried Carbohydrate-rich Food as a Potential Source of Malondialdehyde and Acrylamide: a Consumption Pattern to Evaluate the Risk of Cancer in Population

Background: Tah-Dig (A food rich in carbohydrate that is highly fried) is one of the most popular and tasty Persian food. However, toxic compounds such as malondialdehyde (MDA) and acrylamide are vastly formed in Tah-Dig. The purpose of this study was to investigate the cooking and consumption pattern, intake frequency, acrylamide and malondialdehyde content of Tah-Dig in Iranian population. Methods. The content of acrylamide consumption in population was measured by LC-MS/MS and the MDA in cooking oils used to prepare Tah-Dig was also quantified. Data mining was used to investigate the relationship between the influential factors and Incremental Lifetime Cancer Risk (ILCR). Results. The most consumed type of Tah-Dig among Iranians is Tah-Dig of bread. The highest amount of acrylamide consumed by population was found in potatoes Tah-Dig. The highest MDA content was detected in canola frying oil. Conclusions. Considering data mining analysis, it was shown that the most influential factors related to ILCR are a cumulative factors of Tah-Dig color, portion size, Tah-Dig type, oil type, and the level of education.
From echo chambers to ‘idea chambers’: Concurrent online interactions with similar and dissimilar others

Countering conventional theory, this study found that online homophily and heterophily—connectivity with both similar and dissimilar others—are not necessarily countervailing phenomena, among representative surveys of internet users from five Arab countries: Saudi Arabia, Tunisia, Lebanon, Qatar, and UAE (N = 4,198). Respondents who said the Internet has increased their contact with politically and religiously similar people also tended to say it increased their contact with politically and religiously dissimilar people. A four-item scale measuring online political and religious homophily and heterophily was reliable (a = .754 overall; .79 among Arab nationals), and is referred to in this article as an ‘idea chamber’ index. Confirmatory Factor Analysis and inter-item correlations of scale items are two additional tests that affirm the internal consistency of the measure. Implications for research on digital communication are discussed.
Closeness and other affiliative outcomes generated from the Fast Friends procedure: A comparison with a small-talk task and unstructured self-disclosure and the moderating role of mode of communication

A Fast Friends procedure was created years ago as a method to generate closeness between people interacting for the first time and to provide an experimental procedure to test hypotheses about factors that may lead to initial closeness. In their original study, Aron et al. (1997) validated their closeness-generating task by comparing the degree of interpersonal closeness it generated versus that by a small-talk task. Few subsequent studies, however, have tested the validity of the closeness task by comparing the affiliative outcomes resulting from it with that from other activities. To further examine its validity, this study involved zero-history dyads randomly assigned to become acquainted through either Aron et al.’s closeness-inducing task, Aron et al.’s small-talk task, or an unstructured getting-acquainted task. The dyads were then compared on the closeness they experienced as well as on several other affiliative outcomes. In support of the validity of the closeness-inducing task, the task generated more closeness and other positive outcomes, relative especially to the small-talk task. A second manipulation in the study was the mode of communication (video-chat vs. face-to-face). No significant differences in outcomes (e.g., closeness, liking) were found based on mode of communication. Furthermore, the effectiveness of the closeness task (relative to the other tasks) for generating closeness and other affiliative outcomes was not moderated by the mode of communication.
Dielectric and AC Breakdown Properties of SiO2/MMT/LDPE Micro–Nano Composites

Low-density polyethylene (LDPE) is an important thermoplastic material which can be made into films, containers, wires, cables, etc. It is highly valued in the fields of packaging, medicine, and health, as well as cables. The method of improving the dielectric property of materials by blending LDPE with inorganic particles as filler has been paid much attention by researchers. In this paper, low-density polyethylene is used as the matrix, and montmorillonite (MMT) particles and silica (SiO2) particles are selected as micro and nano fillers, respectively. In changing the order of adding two kinds of particles, a total of five composite materials were prepared. The crystallization behavior and crystallinity of five kinds of composites were observed, the εr and tanδ changes of each material were investigated with frequency and temperature, and the power frequency (50 Hz) AC breakdown performance of materials were measured. The differential scanning calorimetry (DSC) and X-ray diffraction (XRD) results show that the crystallinity of the composites is higher than that of LDPE. Experimental data of dielectric frequency spectra show that the dielectric constants of micro–nano composites and composites with added MMT particles are lower than LDPE, the dielectric loss of composites can be improved by adding MMT particles. The experimental data of dielectric temperature spectra show that the permittivity of SiO2-MMT/LDPE is still at a low level under the condition of 20~100 °C. In terms of breakdown field strength, the SiO2/LDPE composite material increased by about 17% compared with the matrix LDPE, and the breakdown field strength of the materials SiO2-MMT/LDPE and MMT-SiO2/LDPE increased by about 6.8% and 4.6%, respectively.
Online processing of the grammatical aspect marker by L2 Chinese learners

The perfective aspect marker in Chinese is partly functionally similar to inflectional suffixes in Indo-European languages but is non-inflectional and lexical in nature, lying thus at the semantics–syntax interface. This provides us with the opportunity to compare directly the syntactic and semantic constraints during second language (L2) sentence processing. The present study explored how L2 Chinese learners with Indo-European languages as their first languages (L1s) process the Chinese perfective marker. The Competition Model prioritizes syntactic processes entailed by cross-linguistic transfer from the participants’ L1s, but this prediction might be challenged by the concurrent functioning of semantic processes. In an event-related potentials (ERP) experiment, 22 European language-speaking L2 Chinese learners with low to intermediate proficiency level and 20 native Chinese speakers (i.e. the control group) participated. An aspectual agreement paradigm was used for materials. Results showed that in the aspect marker mismatch condition, L2 Chinese learners with a shorter learning experience were more likely to show a P600-like component, indicating a morpho-syntactic routine, supporting thus the predictions of cross-linguistic transfer based on the Competition Model. Those with a longer L2 learning experience were more likely to show an N400-like component similar to native Chinese speakers. This shift from P600 to N400 for more advanced learners suggests that L1–L2 syntactic similarity may exert much stronger influence than semantic constraints for learners with shorter L2 experience.
Are super‐face‐recognisers also super‐voice‐recognisers? Evidence from cross‐modal identification tasks

Individual differences in face identification ability range from prosopagnosia to super-recognition. The current study examined whether face identification ability predicts voice identification ability (participants: N = 529). Superior-face identifiers (exceptional at face memory and matching), superior-face recognisers (exceptional at face memory only), superior-face-matchers (exceptional face matchers only), and controls completed the Bangor Voice Matching Test, Glasgow Voice Memory Test, and a Famous Voice Recognition Test. Meeting predictions, those possessing exceptional face memory and matching skills outperformed typical-range face groups at voice memory and voice matching respectively. Proportionally more super-face identifiers also achieved our super voice-recogniser criteria on two or more tests. Underlying cross-modality (voices vs. faces) and cross-task (memory vs. perception) mechanisms may therefore drive superior performances. Dissociations between Glasgow Voice Memory Test voice and bell recognition also suggest voice-specific effects to match those found with faces. These findings have applied implications for policing, particularly in cases when only suspect voice clips are available.
ASSOCIATION OF DIETARY FATS WITH GUT MICROBIOTA PROFILE: HOW DOES PALM OIL FIT IN?

Diet manipulation alters the gut microbiota composition. Gut dysbiosis is characterised by imbalanced bacteria composition that has been associated with high fat diet. Diets containing high animal fat induce pathogenic bacteria growth and similar bacterial profiles have been identified in obese adults and chronic disease patients. Conversely, diets containing high plant fat increase the abundance of beneficial bacteria. Habitual fat intakes modulate the bacterial species and their metabolites in different geographical locations and ethnicities. Dietary interventions using various degrees of fatty acid saturation reported reduced bacterial diversity in high saturated fatty acid (SFA) diet and increased in high monounsaturated fatty acid (MUFA) diet. However, high polyunsaturated fatty acid (PUFA) diet demonstrated a wide variation in bacterial diversity. These results suggested that the effects of dietary fats on gut microbiota composition are not fully established. Palm oil has almost balanced proportions of saturated and unsaturated fatty acids coupled with unique stereo-specificity fatty acids compositions and nutritional properties, making it the main vegetable oil in the Malaysian diet. However, its effect on the gut microbiota profile is still unknown. This review highlights the abundance of specific bacteria after consuming various dietary fats and proposes potential bacteria profile following the palm oil diet.
The impact of different approaches to the teaching of Grade 5 fraction by three experienced teachers

Background: Many teachers for different reasons recognise the teaching of fraction as a challenge. This research explored the teaching of fraction in Grade 5 by three experienced teachers (Ben, Greg and Will) in KwaZulu-Natal province, South Africa. Aim: The purpose of this study was to investigate the impact of different approaches to the teaching of Grade 5 fraction by three experienced teachers. Method: Three teachers and 177 learners were purposively sampled for this study. Classroom observations, interview and fraction achievement test (FAT) were instruments used for data collection. Hence, this study employed a mixed method, where both quantitative and qualitative data sets were collected at the same time, and the data were analysed at the same time in order to discuss the findings. Results: The quantitative data were analysed using descriptive statistics and analysis of covariance (ANCOVA), whilst the qualitative data were analysed in themes. The results showed that learners of teacher Ben performed significantly better than those of teachers Will and Greg. The findings revealed that a combination of good practices and appropriate use of multiple representations by teacher Ben improved his learners’ achievement in addition of fraction more than other learners taught by the other two teachers. Conclusion: The study recommends that mathematics teachers should endeavour to facilitate learners’ conceptual knowledge of fraction by using appropriate teaching approach in their instruction, namely, learner-centred approach, activity-based learning, use of mother tongue for clarity and use of multiple representations. This recommendation will improve learners’ knowledge and conceptual understanding of fraction and algebra in its entity.
Under what conditions do governments collaborate? A qualitative comparative analysis of air pollution control in China

ABSTRACT Based on the collaborative governance framework, this paper proposes four starting conditions that affect the establishment of intergovernmental collaboration: power imbalance, resource imbalance, prehistory of collaboration and participation of superior levels of government. The interaction of these conditions is tested with collaborative practice among local governments in China to control air pollution. The qualitative comparative analysis results show that wheel-shaped, umbrella-shaped and fan-shaped modes promote collaboration. Non-participation of superior levels of government and strong–strong competition modes inhibit collaboration. External leadership and internal leadership play important roles in the initiation of interlocal collaboration.
