In Vitro Effect of Acidic Challenges on the Physical Properties of Dental Prosthesis Artificial Teeth

Objective: To evaluate the effect of immersion and acid challenge with cola drink on color change ( Δ E), Vickers hardness (VHN) and surface roughness (Ra) of artificial acrylic resin teeth. Material and Methods: The artificial teeth were divided into 6 groups (n= 8): TC (Trilux/Control), BC (Biotone/Control), TAC (Trilux/Acid challenge), BAC (Biotone/Acid challenge), TI (Trilux/Immersion) and BI (Biotone/Immersion). The teeth were embedded in acrylic resin and the labial side was serially polished to provide appropriate flat surface. The samples of TC, BC, TI, BI groups were immersed in artificial saliva and cola drink (coke) for 7 days, respectively. The acid challenge was performed with immersion of samples in coke for 5 min, and subsequently immersion in artificial saliva for 2h. This cycle was repeated at 4 times/day, during 7 days. The tests of VHN, Δ E and Ra were analyzed before and after the challenge and immersion groups. Data was analyzed by ANOVA, Tukey and T test ( α = 0.05) . Results: There was no difference in Ra values between groups after treatments. However, there was a decrease in VHN for all groups. BI (19.2 ± 0.3) presented significantly lower hardness than BAC (19.5 ± 0.9) and BC (20.2 ± 0.5). Groups BI (2.18 ± 0.41) and TI (1.50 ± 0.43) had statistically higher Δ E compared to the other groups . Conclusion: The hardness of resin teeth decreased after acid challenges, but the roughness surface was not affected. The color was more affected by the times of exposure in cola beverage and remineralization in artificial saliva, which were associated to the material degradation.
Effects of CO32–/bicarbonate, Si, and PO43– on Arsenic sorption to HFO

Groundwaters that have elevated arsenic (As) concentrations sometimes have moderate to high ferrous iron concentrations. Soluble As species readily sorb to hydrous ferric oxide (HFO); therefore, conventional water treatment methods that remove soluble iron (Fe) by oxidizing to HFO also remove As. Commonly occurring solutes, including phosphate (PO43–), silica (Si), and carbonate (CO32–), also sorb to HFO, and competition between these substances and As species may interfere with As removal. This study simulated Fe/As removal at the pH values, alkalinities, and concentrations of Si and PO43– typical of central Illinois groundwater. The results suggest that for water with a pH > 7, lowering the pH to 7 can overcome CO32– and Si interferences. Lowering the pH of water containing PO43– improves As removal but not to the degree observed in waters containing CO32– and Si. The Dzombak and Morel surface complexation–diffuse‐layer model fits the sorption data fairly well.
Encapsulation of protein within alginate-inulin matrix for targeted drug delivery system

By using sodium alginate and inulin as the core matrix, targeted release hydrogels were produced through ionotropic gelation method. As for model protein, bovine serum albumin (BSA) was chosen for in-vitro assessments. It appeared that amount of inulin had major impact on the encapsulation of BSA and also stability of hydrogels in simulated gastro intestinal fluid. The encapsulation efficiency of BSA was enhanced as the amount of inulin incorporated into the hydrogels was increased. In addition, only a little amount of BSA was released throughout 2 hours in simulated gastric fluid, SGF exposure. However, after changing into simulated intestinal fluid, SIF 100% of protein was released within 1.5 hours. Lower swelling index has been observed from alginate-inulin hydrogels in acidic condition (pH 1.2) as compared to alkaline medium, phosphate buffer (pH 7.4). This phenomenon is an indicative of pH responsive swelling activities. These hydrogels were characterized by Fourier-Transform Infared spectroscopy and Scanning Electron Microscopy for protein-excipients and hydrogels surface morphology, respectively. These developed alginate-inulin hydrogel has demonstrated high stability in acidic medium and good release efficiency at the targeted area.
Organic salts enhanced soil risk elements leaching and bioaccumulation in Pistia stratiotes.

It is well known that organic chelates have a positive influence on micronutrients mobilisation. The objective of the present study was to investigate the efficiency of organic acid salts to enhance mobility of Cd, Pb, and Zn in soil with subsequent bioaccumulation in water plant (P. stratiotes). Column flushing and pot rhizofiltration experiment were conducted. Statistical analyses ANOVA with Tukey’s HSD test were used for results analysis. Results revealed statistically different efficiency of four tested organic acid salts ( P < 0.05). Ammonium citrate was the most effec o tive for release of all three risk elements. Cd, Pb, and Zn were mobilised by 45%, 321%, and 116% more than under 0.11 mol/L acetic acid (exchangeable form), respectively. Ammonium oxalate and acetate proved lower efficiency (P < 0.05). Young plants showed higher bioconcentration factor (BCF) than old ones in leaves as well in roots. Old plants proved lower residual metal concentration in solution. Mobilisation efficiency and metals accumulation in biomass were the highest under citrate and tartrate treatments.
Predicting contemporary range‐wide genomic variation using climatic, phylogeographic and morphological knowledge in an ancient, unglaciated landscape

Understanding the spatial distribution of genetic variation across a species’ range is a central tenet in evolutionary biology and the ability to predict such patterns is valuable to conservation management. Genetic diversity and differentiation may be explained by present‐day niche centrality, historical processes, or morphological variation across a species’ range, yet few studies evaluate these factors concurrently. Moreover, there is a particular lack of knowledge of the influence of these factors in ancient, unglaciated landscapes of the Southern Hemisphere. We investigate these concepts for their influence upon spatial patterns of genetic variation in a widespread plant species in a southern biodiversity hotspot.

In-ovo Effects of Lysine Amino Acid on Histomorphometry of Thigh Muscles, Cecal Tonsils and pH in Japanese Quail

The current was carried out to investigate the in-ovo effect of lysine on the histology of Thai muscles, their pH and Cecal tonsil in the Japanese quails. At 1st day of hatching, total number of 240 quail eggs was injected with four different solutions. G-1st was kept as control and injected with sterile distilled water. G-2nd was injected with 1g/50 ml sterile distilled water solution of lysine. G-3rd was injected with 2g/50 ml sterile distilled water solution of lysine. G-4th was injected with 3g/50 ml sterile distilled water solution of lysine. In-ovo treated eggs hatched at 17th day. Birds after hatching divided into four groups. All the birds of four groups reared on the same diet. Three birds per replicate (n=05) were selected for slaughtering and samples were collected for histological analysis. In-ovo inoculation of lysine at the level of 3g/50 ml sterile distilled water solution has considered more beneficial effects on the histo-morphometry of cecal tonsils, thai muscles. Improvement in the histology of cecal tonsils indicated the immunity level and thai muscles indicating the muscles growth and meat quality of quail birds.
Box–Behnken design for removal of uranium(VI) from aqueous solution using poly(ethylene glycol) based dicationic ionic liquid impregnated chitosan

Poly(ethylene glycol) bis(methylimidazolium) di[bis(trifluoromethylsulfonyl)imide] was synthesized as an ionic liquid and impregnated onto chitosan. The removal of uranium(VI) ions from aqueous solution was investigated with batch sorption tests using ionic liquid impregnated chitosan. Response surface methodology based on 3 level Box–Behnken design was applied to analyze the effect of initial pH (4–6), initial concentration (20–60 mg L-1), contact time (15–105 min), and temperature (30–50 °C) on the uptake capacity of uranium(VI). Main effect of initial concentration, quadratic effect of contact time, and dual effect of initial pH and contact time were found statistically significant based on analysis of variance (ANOVA). Probability F-value (F = 1.49 ×10-6) and correlation coefficient (R2 = 0.96) point out that the proposed model is compatible with experimental data. The maximum uptake capacity of uranium(VI) was found as 28.48 mg g-1 at initial pH 4, initial concentration 60 mg L-1, contact time of 70 min, and a temperature of 50 °C. Sorption kinetics followed a pseudo-second-order model and Freundlich model was obtained to fit the sorption data. The presence of competing ions slightly reduced uranium(VI) sorption and the selectivity order can be given as UO22+>Zn2+>Ni2+.
An Analysis of Haskell Parallel Programming Model in the HaLVM

Recently, cloud computers are widely used due to the development of computing environment and network speed. Unikernel is considered to be an attractive operating system in the manycore environment that effectively provides cloud computers. HalVM is a unikernel coded in Haskell. In this paper, we analyze the performance of Haskell running in a unikernel, which has shown good parallel programming performance in a manycore environment. In this paper, we analyze the performance of Haskell running in a unikernel, while Haskell has shown good performance in a manycore environment. To do this, we select HaLVM as the target operating system and analyze the performance by testing various Haskell parallel programming models. Test result shows that HaLVM is scalable only on IVC. We also implement a library to make programming with IVC more convenient, and use this library to compare extensibility experiments. Our test shows HaLVM’s scalability is 112.42% higher than Linux environment.
Management practice to optimize wheat yield and water use in changing climate

ABSTRACT Field experiments for six seasons (2008–2013) for present time slice (PTS; 2008–2013) and simulation studies for mid-century (MC; 2021–2050) were carried out to assess different planting dates, varieties and irrigation schedules in addressing the impact of climate change on grain yield and water use efficiency (WUE) in bread wheat (Triticum aestivum L.). During field experimentation, WUE (averaged over other treatment) was unaffected by planting date; however, it was 6% higher in late variety (V1) than early variety (V2). Simulation study suggested that in MC, increase in maximum and minimum temperatures compared to PTS would reduce wheat yield by 17–27%. In MC, WUE would be reduced by 14.8% due to shortening of crop duration (1–11 days). The reduction in WUE could be ascribed to relatively more reduction in yield (22%) than evapotranspiration (ET) (4%). The WUE in MC3 (2041–2050) was relatively more than MC1 (2021–2030) and MC2 (2031–2040) due to more yield and less ET. Delaying planting date of wheat crop by 15–30 days in this region emerged as the best adaptation measure to tackle climate change impact for sustaining yield and having higher WUE in MC.
A lungfish survivor of the end-Devonian extinction and an Early Carboniferous dipnoan radiation

Until recently the immediate aftermath of the Hangenberg event of the Famennian Stage (Upper Devonian) was considered to have decimated sarcopterygian groups, including lungfish, with only two taxa, Occludus romeri and Sagenodus spp. , being unequivocally recorded from rocks of Tournaisian age (Mississippian, Early Carboniferous). Recent discoveries of numerous morphologically diverse lungfish tooth plates from southern Scotland and northern England indicate that at least 10 dipnoan taxa existed during the earliest Carboniferous. Of these taxa, only two, Xylognathus and Ballgadus, preserve cranial and postcranial skeletal elements, which have yet to be described. Here we present a description of the skull of a new genus and species of lungfish, Limanichthys fraseri gen. et sp. nov., which hails from the very earliest Tournaisian in the Ballagan Formation of Burnmouth, southern Scotland. The new specimen represents the earliest definitive Tournaisian lungfish skull material, thus providing an invaluable insight into the response of this group – and, indeed, Sarcopterygii as a whole – immediately following the latest Devonian Hangenberg event. Phylogenetic analysis places Limanichthys fraseri within the Devonian ‘phaneropleurid-fleurantiid’ grade of lungfish and shows that the Carboniferous lungfish represent forms that have their origins deep in the Middle and Late Devonian as well as those from a unique Carboniferous radiation. http://zoobank.org/urn:lsid:zoobank.org:pub:101FFE43-42D5-4950-9169-A900113B6F1D
Post-normal science communication: exploring the blurring boundaries of science and journalism

This article provides a framework for analysing changes and continuities in science communication. The field is challenged by three contexts: (1) ‘post-normal situations’ of coping with uncertainties, value questions, an urgency to take action, and associated political pressures; (2) a dramatically changing media environment, and (3) a polarizing discourse culture. We refine the concept of post-normal science to make it more applicable to analyse public science communication in an era of digital media networks. Focussing on changes in the interactions between scientists and journalists, we identify two ideal types: normal and post-normal science communication, and conclude that the boundaries of science and journalism are blurring and under renegotiation. Scientists and journalists develop new shared role models, norms, and practices. Both groups are increasingly acting as advocates for common goods that emphasize the emerging norms of post-normal science communication: transparency, interpretation, advocacy and participation.

Investigating the impact of the media on international sporting events and the extent of tourist attraction at that event

Purpose: The aim of the study was to investigate the effect of media on international sports events on tourist attraction, for this purpose, research and reports related to holding sporting events were studied. Methodology: Systematic review of related articles from previous years. The basis for collecting material related to the impact of the media on attracting tourists to sporting events has achieved the desired result. Results: Media and networks provide diverse and exciting services to their audiences, most people consider media as the main source of information and an influential factor in life and social affairs, no doubt watching sports events As well as information on activities Exercise is one of the things that makes sports and friends more interested in the media. Using advanced imaging and visual arrangements, television images capture scenes of victory in a sporting event in a way that is seen by viewers as a great victory. Sports and the media, especially in the realm of popular sports, focus on special people It gives them heroism and transnational and transnational patterns to communicate more effectively with their audiences. Also, the media, as part of the new structure of society and one of the most widespread and widely available devices in all countries, plays a critical role in various political, cultural, social and economic fields, so the press, radio, television and the site. In today's sports, the world and Iran can be introduced as a driving force for cultural and sports. Conclusion: The results showed that the expansion and development of mass media is such that today's human beings can be considered as the medium of new media and culture as a product of mass media advertising; on the other hand, sports as one of the cultural, social and public issues. And publicity is of particular importance in societies, religions, and denominations, so the attraction of sport at the international level can provide the basis for the friendship of nations, positive cultural exchanges, coexistence, and mutual understanding. As a result, the more media coverage of an event It also attracts more tourists. Suggestions: The media coverage of sports in the world should be such that it emphasizes the promotion of cultural values in society and promotes desirable characteristics and moral virtues among the people.
REMOVAL OF SOME ADVANCED DYES FROM AQUEOUS SOLUTION USING MODIFIED KAOLINITE CLAY

Kaolin mineral and its modified forms were used for dye removal from aqueous solutions. The affecting parameters such as pH, dye concentration and contact time on the removal performance were investigated. Three different dyes (acid Green 25, Basic Blue 3 and Disperse Orange 13) were studied. The removal has a higher rate at initial period of contact time. The equilibrium is achieved at 120 min. The adsorption is occurring through transport of dye molecules from solution to solid surface. Then, they diffused into the pores. The order of adsorption was: Basic blue 3 > Acid Green 25 > Disperse Orange 13. The adsorption process follows the pseudo-second-order kinetics. The rate controlling step is not depending on the intra-particle diffusion. A Freundlich isotherm model could describe the adsorption. The calculated (RL) factor confirmed the variability of the adsorption process.
Stability Analysis to Study the Effects of Different Date of Sowing on Grain Yield Performance in Wheat (Triticum sp.)

At global level, wheat occupies an area of 221.68 mha, with a production and productivity of 728.28 mt and 32.9 q/ha respectively. India’s share in world wheat area is about 12.50 %, whereas it occupies 12.05 % share in the total world wheat production, which is the second largest after China (USDA, 2016). In India wheat occupies an area of about 31.23 mha with a production of 98.38 mt. and average productivity of 32.16 q/ha (Indian Institute of
METAHEURISTICS FOR THE WASTE COLLECTION VEHICLE ROUTING PROBLEM IN URBAN AREAS

This paper presents a methodology for solving the municipal waste collection problem in urban areas. The problem is treated as a distance-constrained capacitated vehicle routing problem for municipal waste collection (DCCVRP-MWC). To solve this problem, four meta-heuristic algorithms were used: Genetic algorithm (GA), Simulated annealing (SA), Particle swarm optimization (PSO) and Ant colony optimization (ACO). Vehicle guidance plays a huge role in large transportation companies, and with this test, we propose one of several algorithms for solving urban waste collection problems.
Effects of sources of dietary protein supplemented to oat-vetch hay mixture on milk yield and milk composition of crossbred dairy cows

The experiment was conducted in Debre Zeit Agricultural Research Center with the objective of evaluating the effects of sources of dietary protein supplemented to oat-vetch mixture hay on milk yield, milk composition and profitability in lactating crossbred dairy cows. Four high grade cross bred (Holstein Friesian × Boran) dairy cows with similar lactation stage (mid lactation) and parity were used. The experimental diets were T1 (ad libitum oat-vetch hay + noug seed cake), T2 (ad libitum oat-vetch hay + cottonseed cake), T3 (ad libitum oat-vetch hay + linseed cake) and T4 (ad libitum oat-vetch hay + mixture of the three oil seed cakes). A 4 × 4 Latin square design was used for the feeding experiment with four dietary treatments assigned to animals at random initially. The animals were offered hay at a rate sufficient to allow for a 20% refusal and the amount of concentrate offered was at 0.5 kg/l of milk in all treatments. The concentrate mix consisted of 33% oil seed cakes (OSC), 66% wheat bran and 1% salt. Treatment effects on milk yield, milk fat, milk protein, lactose and total solids were significantly different (P<0.05). Economic analysis showed that T2 based supplementation was feasible than the remaining dietary treatments. Therefore, it can be concluded that T2 can optimize both biological and economic response of dairy cows. Key words: Cottonseed cake, dairy cow, linseed cake, milk, noug seed cake, oat-vetch, wheat bran.
