Investigating the Removal Rate of Acid Blue 113 from Aqueous Solution by Canola

Introduction: Industrial wastewater is one of the major environmental pollutants. Discharge of the colorful industrial effluent into the receptive waters leads to eutrophication and has mutagenic and carcinogenic properties. Therefore, the aim of this study was to investigate the removal of acid blue113 from aqueous solutions by Canola (Brassica Napus) waste. Materials and Methods: This is an experimental-lab study. Canola waste was used as an adsorbent to remove the acid blue113 dye. The effect of various parameters on adsorbent performance was investigated. The isotherms of adsorption were determined. The dye concentration was measured in wavelength of 566 nm by spectrophotometer. Results: The results indicated that the removal rate of dye increased with increasing the contact time and dose of adsorbent but the amount of adsorbed dye per gram adsorbent (qe) decreased. The removal rate increased with decreasing the initial concentration of dye, too. In the optimum state, the adsorbent could adsorb about 99 percent of the dye. The data of adsorption were best fitted to Langmuir isotherm. Conclusion: This study indicated that Canola waste can be used as an effective and inexpensive adsorbent to treat of textile effluents

Numerical and Experimental Analyses of a Lighting Pole in Terms of Passive Safety of 100HE3 class

Nowadays trends related to the road safety make the lighting poles producers meet rigorous requirements that decrease the risk of death and injury of vehicle drivers in case of the impact. New requirements are in force from 1 January 2015, when Road and Bridge Research Institute informed that each pole liable to a direct vehicle impact has to meet Standard PN-EN 12767. The article presents the design of a novel, safe lighting pole. The novelty lies in the pole simplicity, which results in the manufacturing technology the cost of which is comparable to that of the conventional pole. Compared to the conventional poles of thickness 3 mm and greater, this one is made of thin-walled steel sheet of increased strength parameters and specially designed sleeve that is fixed to the base plate. The crash tests carried out on the track for the impact experiments proved that the requirements of the standards in the driver highest safety class and in the high vehicle kinetic energy absorption were satisfied both for the speed impact 35 km/h and 100 km/h. The numerical model for simulations of the vehicle behaviour during and after the impact was implemented in software Ansys LS-Dyna. The simplifications of some elements were of negligible influence on the analysed phenomena. The comparative parameters were ASI, THIV and exit velocity of the vehicle. The numerical results were close to the empirical ones, therefore they confirmed that finite element analysis can be successfully applied at the stage of elaborating of the initial concepts of the road lightning poles. It follows that the number of expensive crash tests can be reduced.
Does a positive density perception increase the probability of living in the ideal housing type? Evidence from the Loire-Atlantique Département in France.

What does the ideal housing type look like? A 2015 online survey of individuals living in the Loire-Atlantique Departement in France provided 1,134 interviews, which we analyze using a mixed-effect probit model. We look at the probability of living in the ideal housing type related to 28 variables of dwelling and respondent characteristics, density perception, district perception, type of municipality, and proximity to education, healthcare and food facilities. The issue is important because certain housing types yield greater land consumption and longer trips. Local governments support infill developments with higher built-up density levels to conserve land and support walking, cycling, and transit. We find that the probability of living in the ideal housing type has no relationship to density perception. What matters is a positive district perception and proximity to healthcare. Well-designed infill development with higher built-up density levels can succeed, associating a higher probability of living in the ideal housing type with suitable urban forms given the physical constraints of territories, in a sustainable development framework.
On nonsingularity and group invertibility of combinations of two group invertible matrices

Let A and B be two group invertible matrices, we study the rank, the nonsingularity and the group invertibility of A − B, AA] − BB], c1A + c2B, c1A + c2B + c3AAB where c1, c2 are nonzero complex numbers. Under some special conditions, the necessary and sufficient conditions of c1A + c2B + c3AB and c1A + c2B + c3AB + c4BA to be nonsingular and group invertible are presented, which generalized some related results of Benı́tez, Liu, Koliha and Zuo [4, 17, 19, 25].
First-Principles Molecular Dynamics Insight into Fe2+ Complexes Adsorbed on Edge Surfaces of Clay Minerals

Using first-principles molecular-dynamics simulations, probable inner-sphere complexes of Fe2+ adsorbed on the edge surfaces of clay minerals were investigated. Ferrous ions are important reductants in natural processes and their properties can be altered significantly by complexation on edge surfaces of clay minerals. However, the microscopic picture of adsorption sites and structures of Fe2+ is difficult to reveal with modern experimental techniques and, therefore, remains unclear. From the results of first-principles molecular-dynamics simulations, evidence has been provided that complexes on ≡Si—O sites were the most stable forms, which should be responsible for the experimentally observed pH-dependent uptake. Such complexation was found to be strong enough to distort the local coordination structures of Si—O tetrahedra in the substrate. Analyses showed that Fe2+—Owater coordination structures were dominated by the solvent with surface groups participating in the complexes via H bonding. The present study provided a microscopic basis for understanding the chemical processes involving surface-complexed Fe2+ ions.

From crab shell to solar cell: a gel polymer electrolyte based on N-phthaloylchitosan and its application in dye-sensitized solar cells

Chitosan, a biopolymer derived from crab shells which is insoluble in common organic solvents has been converted to the organosoluble N-phthaloylchitosan (PhCh) by reaction with phthalic anhydride in dimethylformamide (DMF). The formation and structure of PhCh was confirmed by the characteristic peaks of phthalimido and aromatic groups observed at 719, 1708 and 1772 cm−1 and two sets of peaks centered at 3.0 and 7.5 ppm obtained from FTIR and 1H NMR analyses respectively. Gel polymer electrolytes consisting of PhCh, ethylene carbonate (EC), and DMF with various amounts of tetrapropylammonium iodide (TPAI) and iodine were prepared. The interaction behavior between polymer–plasticizer–salt was thoroughly investigated using FTIR spectroscopy. The gel polymer electrolyte consisting of PhCh : EC : DMF : TPAI : I2 in a weight ratio (g) of 0.1 : 0.3 : 0.3 : 0.12 : 0.012 showed the highest conductivity of 5.46 × 10−3 S cm−1 at room temperature and exhibited the best performance in DSSCs with efficiency of 5.0%, with JSC of 12.72 mA cm−2, VOC of 0.60 V and fill factor of 0.66.
Study of biosorption of copper and silver by marine bacterial exopolysaccharides

Metal bioremediation was studied by biosorption of analytical grade copper Cu(II) and silver Ag(I) by an exopolysaccharide (EPS) produced by marine bacteria from French Polynesia. Colorimetric analysis showed that EPS was composed of neutral sugars, uronic acids, acetate and especially high sulfate amount (29%). Metal biosorption experiments were conducted in batch process. Results showed that the maximum sorption capacities calculated according to Langmuir model were 400 mg g−1 EPS (6.29 mmol g−1) and 256 mg g −1 EPS (2.38 mmol g −1 ) for Cu(II) and Ag(I), respectively. The influence of pH, biosorbent concentration, ionic strength on EPS biosorption capacities was investigated.
DECIDUOUS MOLAR HYPOMINERALIZATION IN TWINS: A CASE REPORT / HIPOMINERALIZAÇÃO DE MOLARES DECÍDUOS EM GÊMEOS: UM RELATO DE CASO

Deciduous molar hypomineralization (DMH) is an enamel defect of multifactorial origin that affects the second deciduous molar and may be associated with canines and first deciduous molars. Clinically, these defects appear as white, yellow, or brown spots, which may progress to a posteruptive enamel breakdown, increasing sensitivity and caries risk. Children with DMH are more prone to develop MIH in permanent dentition. The aim is to present a clinical case of monozygotic twins with severe DMH, showing evidence of its manifestation as well as clinical characteristics and aetiological factors involved. Although DMH etiology remains unclear, clinical manifestations in twins suggest a possible genetic susceptibility to the disease, which may be associated with the shared environmental factors. Also, teeth affected with DMH require an increased need for restorative care. Aetiological risk factors and different treatments’ knowledge regarding this condition are of substantial importance to improve patients’ quality of life. More studies involving monozygotic and dizygotic twin pairs will be required to improve this case report data.
Adsorption of added phosphorus as influenced by the application of lime and gypsum in an acid Alfisol of Himalayan region

A bulk soil sample of acid Alfisol (pH 5.8) was used for adsorption studies in the laboratory and the data for plotting phosphate adsorption isotherms were obtained as per the procedure of Fox and Kamprath (1970). The adsorption maxima and the index of bonding energy were calculated in accordance with the Langmuir adsorption equation. Phosphate adsorption studies showed that the experimental soil had a greater affinity for P as the P adsorption continued to rise with increase in equilibrium P concentration. The lime applications (1.5 and 3.0 t ha−1) increased and gypsum application (2.7 and 5.4 t ha−1) decreased the P adsorption. The lower level of gypsum application was superior in declining the P adsorption to its higher level. The values of P adsorption maxima (b) and index of bonding energy (k) were 2186 μg g−1 and 0.015 mL μg−1 under control (no lime, no gypsum) and 2381 μg g−1 and 0.029 mL μg g−1, respectively under lime (3 t ha−1) which were reduced to 2041 μg g−1 and 0.007 mL μg g−1, respectively under 2.7 t ha−1 gypsum application.
Differential branching fractions and isospin asymmetries of B → K[superscript (*)]μ[superscript +]μ[superscript −] decays

The isospin asymmetries of B → Kμ+μ− and B → K∗μ+μ− decays and the partial branching fractions of the B0 → K0μ+μ−, B+ → K+μ+μ− and B+ → K∗+μ+μ− decays are measured as functions of the dimuon mass squared, q2. The data used correspond to an integrated luminosity of 3 fb−1 from proton-proton collisions collected with the LHCb detector at centre-of-mass energies of 7 TeV and 8 TeV in 2011 and 2012, respectively. The isospin asymmetries are both consistent with the Standard Model expectations. The three measured branching fractions, while individually consistent, all favour lower values than their respective Standard Model predictions.

Hepatorenal and Testicular Functions Concomitant with Induced Hypo and Hyperprolactinemia in Male Rats

| This study aimed to investigate early effects of induced hypo and hyperprolactinemia on hepatorenal and testicular functions in rats. Sixty mature male Albino rats were equally divided into 3 groups; control, hypoprolactinaemic (HypoP) and hyperprolactinaemic (HyperP). Treatments continued for one month then individual blood samples were subjected to estimate prolactin “PRL” and testosterone “T” hormones, liver aspartate aminotransferase “AST”, alanine aminotransferase “ALT” and bilirubin as well as kidney functions and malondialdehyde “MDA”. Testes were weighed to calculate gonadosomatic index (GSI) and individual semen samples were collected for semen evaluation. Tissue samples were obtained for histopathology and transmission electron microscopy (TEM). HypoP or hyperP did not change GSI and kidney functions. hypoP increased AST and ALT while hyperP increased AST, ALT, bilirubin and MDA with drop in T level and increased sperm abnormalities. Histopathology revealed mild degeneration in liver, kidneys and testes of hypoP while hyperP showed moderate degeneration in these organs. By TEM, the liver of hypoP displayed nearly normal structure, while in hyperP liver appeared with bundles of collagen fibers, ITO cells and swelling of mitochondria. Kidneys of hypoP showed mild degeneration while hyperP revealed bundles of collagen fibers periglomerular and swelling of mitochondria. It appears that hypoP has minimal effects on liver functions without affecting kidney and testicular functions. Excess PRL is considered a stressor resulting in elevation of MDA with deleterious influence on liver, kidney and testes functions.
Phosphorus Adsorption in Relation to Soil Characteristics of Vertisols Derived from Different Parent Materials

Phosphorus adsorption behaviour of Vertisols derived from different parent materials was studied. Both Langmuir and Freundlich adsorption isotherms gave good fits when native phosphorus pool was also considered while fitting the adsorption isotherms. Vertisols derived from basaltic and limestone have high phosphorus adsorption capacities compared with those of grey shale, granodiorite and granitic-granodiorite parent materials. Mean adsorption maximum values for different pedons may be arranged as: pedon 5 (limestone) > pedon 2 (basalt) > pedon 1 (grey shale) > pedon 3 (granitic-granodiorite) > pedon 4 (granodiorite). Phosphorus adsorption is significantly correlated with clay content.
Formation and Restacking of Disordered Smectite Osmotic Hydrates

Clay swelling, an important phenomenon in natural systems, can dramatically affect the properties of soils and sediments. Of particular interest in low-salinity, saturated systems are osmotic hydrates, forms of smectite in which the layer separation greatly exceeds the thickness of a single smectite layer due to the intercalation of water. In situ X-ray diffraction (XRD) studies have shown a strong link between ionic strength and average interlayer spacing in osmotic hydrates but also indicate the presence of structural disorder that has not been fully described. In the present study the structural state of expanded smectite in sodium chloride solutions was investigated by combining very low electron dose, high-resolution cryogenic-transmission electron microscopy observations with XRD experiments. Wyoming smectite (SWy-2) was embedded in vitreous ice to evaluate clay structure in aqua. Lattice-fringe images showed that smectite equilibrated in aqueous, low-ionic-strength solutions, exists as individual smectite layers, osmotic hydrates composed of parallel layers, as well as disordered layer conformations. No evidence was found here for edge-to-sheet attractions, but significant variability in interlayer spacing was observed. Whether this variation could be explained by a dependence of the magnitude of long-range cohesive (van der Waals) forces on the number of layers in a smectite particle was investigated here. Calculations of the Hamaker constant for layer-layer interactions showed that van der Waals forces may span at least five layers plus the intervening water and confirmed that forces vary with layer number. Drying of the disordered osmotic hydrates induced re-aggregation of the smectite to form particles that exhibited coherent scattering domains. Clay disaggregation and restacking may be considered as an example of oriented attachment, with the unusual distinction that it may be cycled repeatedly by changing solution conditions.

Regional and subregional analyses of macroeconomic policy strategies for growth and equality in Southern Africa

We investigate the relevance of beta (β, absolute and conditional) and sigma (σ) convergence in the economies of the Common Monetary Area of Southern Africa and in the provinces of the Republic of South Africa using panel data, allowing an understanding of growth and inequality in the region. The region has experienced β- and σ-convergence; however, growth rates of per capita gross domestic product are low at aggregate and sectoral levels. At sectoral level, the performance of the tertiary sector is better than that of the primary and secondary sectors. The relatively poor performance of the primary and secondary sectors needs policy attention. For the provinces of South Africa, capital expenditure on key sectors such as education and health can enhance growth rate, whereas the overall revenue expenditure retards growth. Therefore, provinces’ capital budgets need to be managed well within the limitation of revenue expenditure to avoid fiscal imbalances.
