An Insight Analysis of Nano sized powder of Jackfruit Seed

The preparation of biodegradable nanomaterials by blending starch nanocrystals with various polymer matrices are the most active research. This work reports aspect related to nano-sized particles of jackfruit seed. This approach is simple, faster, eco-friendly, cost effective and suitable for large scale production. X-Ray Diffraction studies analyze particles size, morphology, type of starch and degree of crystallinity. The particle size is found to be 12nm, specific surface area is 625m 2 /g, contains A-type starch and 32% degree of crystallinity. A morphology index (MI) is developed from FWHM of XRD data to understand interrelationship of particle size and specific surface area. MI range is from 0.50 to 0.74. It is correlated with the particle size and specific surface area. It is observed that MI has direct relationship with particle size and an inverse relationship with specific surface area.
NEMS Based on Carbon Nanotube: New Method of Control

A new method to control the motion of nanotube‐based nanoelectromechanical systems is proposed. Namely, the chemical adsorption of atoms and molecules on the open edges of the single‐walled carbon nanotube leads to the appearance of electric dipole moment. In this case the nanotube can be actuated by a nonuniform electric field. Electric dipole moments of the carbon nanotubes with functionalized edges are calculated. Possibility of the method proposed is shown on example of the gigahertz oscillator. The parameters of the system and control force which allow obtaining the stationary operation with constant frequency are determined.
Separation of mycotoxins, polycyclic aromatic hydrocarbons, quinones, and heterocyclic compounds on cyclodextrin bonded phases: An alternative lc packing

Abstract β-Cyclodextrin and γ-cyclodextrin chiral bonded phases were previously shown to be useful in the separation of enantiomers, diastereomers and structural isomers. In this work it is demonstrated that these stationary phases are also useful in more routine separations. As such, they provide an alternative to the popular reverse phase packings. Because the selectivity of cyclodextrin packings is often unique they can be used to compliment conventional columns, particularly when separating complex mixtures where peak overlap is a problem. The separation of several important classes of compounds is used to demonstrate the general utility of this packing.
A rheological investigation of the role of water in wheat flour doughs

Summary. Doughs of wheat flour, salt and water have been mixed to various levels of work input and water content. Rheological tests have shown that above a particular water content the dough system is unaffected by further addition of water. It is proposed that the water in dough is held with various degrees of strength and that the distribution of water is dependent upon the mechanical work input.
SEMICLASSICAL ELECTRONEGATIVITY AND CHEMICAL HARDNESS

The semiclassical path integral approach is undertaken to develop new definitions and atomic scales of electronegativity and chemical hardness. The considered quantum probability amplitude up to the fourth-order expansion provides intrinsic electronegativity and chemical hardness analytical expressions in terms of principal quantum number of the concerned valence shell and of the effective atomic charge including screening effects. The present electronegativity scale strikes on different orders of magnitude down groups of the periodic table, while still satisfying the main required acceptability criteria regarding the finite difference–based scale. The actual chemical hardness scale improves the trend across periods of the periodic system, avoiding the usual irregularities within the old-fashioned energetic picture. The current quest introduces the electronegativity of an element as the power by which the frontier electrons are attracted to the center of the atom being a stability measure of the atomic system as a whole.
Physiological responses of canola and wild mustard to salinity and contrasting calcium supply

Abstract Growth, ion balance, water relations and leaf photosynthesis of canola (Brassica napus L., cv. Excel) and wild mustard (Brassica kaber L. C. Wheeler) grown under a mixture of sodium and magnesium sulphate salts were examined using a hydroponic system in a growth chamber. Wild mustard was less salt tolerant than canola, based on the growth responses. Salinity caused large accumulation of sodium (Na) and magnesium (Mg) ions, but reduced calcium (Ca) and potassium (K) concentrations in the shoots and roots. Water potential, osmotic potential, transpiration, stomatal conductance and hydraulic conductance decreased to a greater extent in canola than in wild mustard, indicating salinity imposed a smaller osmotic effect on the wild species. Calcium addition improved the growth of wild mustard more than canola but it had no effect on water relations. The growth reduction in these species under salt stress resulted from a combination of ion toxicity, insufficient nutrient ion availability and altered wate.
Psychological epidemiology of sexual function change after conization for cervical dysplasia

Summary Purpose of investigation: To evaluate psychological impact of sexual function change after conization for cervical dysplasia. Materials and Method: Seventy-seven sexually active women enrolled in this study. Before conization, each participant’s sexual function was assessed using the Female Sexual Function Index (FSFI) and trait anxiety was assessed. At least six months after surgery, each woman again completed the questionnaires. The authors compared the results before and after conization according to anxiety. Results: The pa- tients with anxiety towards sex after conization had changes in all aspects of sexual function versus those without anxiety for sex ( p < 0.05). Patients with mild trait anxiety showed sexual function changes in arousal, orgasm, dyspareunia, and satisfaction compared to those without trait anxiety. Conclusion: Changes in sexual function after conization are more pronounced in patients who express anxiety regarding sex, or have a trait anxiety, compared to those without anxiety. Therefore, psychological counseling should be empha- sized before conization.
Chemically activated carbon on a fiberglass substrate for removal of trace atrazine from water

Chemically activated fiber (CAF) for removal of trace atrazine from water was prepared by coating fiberglass assemblies with a phenolic resin along with a chemical activation agent of ZnCl2, then stabilization and heat treatment in N2 at 500 °C. The carbon on the CAF shows similar BET surface area and volumes of narrow micropores (<10 A), higher volumes of wide micropores (10–20 A) and narrow mesopores (20–50 A), as compared with a commercially available GAC F-400. Adsorption isotherm data show that the CAF has a higher adsorption capacity for atrazine than the GAC, primarily because the CAF has an increased pore (10–50 A) volume. The breakthrough tests show that the CAF filter is ten times more effective over the GAC filter in removing the atrazine to below the current USEPA standard of 3 ppb. The CAF filter also shows a better competitive adsorption of atrazine over the GAC filter in the presence of 50 times higher concentration of humic acid. Such a filter can be regenerated to 90% of its original activity by heating at 350 °C in air.
A prediction method for power transformer state parameters based on feature attention mechanism

Precise predictions on state parameters of power transformers could provide a comprehensive assessment of current operation status and potential risks on equipment. In the proposed power transformer prediction model, a feature attention mechanism is introduced to basic long short-term memory network (FA-LSTM) to mining the association rules between the target attribute and its relevant features like grid operation and meteorological data. Compared to previous researches treating the attributes as independent ones, the relationship extracted through time iterations could correct prediction results by offering auxiliary information for target series. Additionally, the feature attention is not restricted by the preset threshold value in traditional association rule mining algorithms. In the case study of predicting the concentration of dissolved hydrogen in insulating oil, experiments show that our proposed FA-LSTM outperforms traditional methods with lower absolute percentage errors, giving a more accurate result for time series prediction of power transformer state parameters.
Corrosion behaviour of a new Ti‐6Al‐2Nb‐1Ta alloy in various solutions

A new Ti‐6Al‐2Nb‐1Ta alloy was obtained for to satisfy the mechanical and anticorrosion requirements in neutral corrosive environment. The corrosion behaviour of this new Ti‐6Al‐2Nb‐1Ta alloy in 0.1 M Na2SO4, 3% NaCl solutions and synthetic sea water was studied in this paper, using potentiodynamic and linear polarisation method, electrochemical impedance spectroscopy (EIS) and monitoring of the open circuit potentials. The structure of the alloy represents an α + β uniform structure with un‐oriented grains. From the potentiodynamic polarisation curves it resulted that the studied alloy is self‐passivated in all three solutions having a very good and very easy tendency to passivation. The most favourable values of the electrochemical parameters were registered in 0.1 M Na2SO4 solution due to its reduced corrosivity. EIS measurements proved the improvement of the passive layer resistance with the immersion time. An electric equivalent circuit with two time constants was fitted. The values of the polarisation resistances showed very good protective capacities which improved in time. The open circuit potentials have the general tendency to ennoble in time, suggesting the thickening of the passive films and the increase of their protective capacities.
Composition and Crystallization of Hydroxyapatite Coating Layer Formed by Electron Beam Deposition

To improve the biocompatibility of Ti-based metal implants, a hydroxyapatite (HA) coating layer was formed on the surface by electron-beam deposition. The dissolution rate of the coating layer was strongly dependent on the layer's calcium/ phosphorus (Ca/P) ratio. Layers with a Ca/P ratio close to that of crystalline HA (Ca/P = 1.67) showed good stability in a physiologic saline solution. When the layer was crystallized by heat treatment in air at temperatures between 400° and 500°C, the stability was enhanced further while maintaining good interfacial bonding strength with the substrate. Preliminary in vivo tests on rabbits indicated that heat treatment and the resultant enhancement in stability are beneficial for bone attachment to the implants.
Comparing Study of The Stability and spectral properties vibrations for some Tellurium (IV) compounds containing cycloctadienyl group by Quantum Mechanical Calculations

Density Functional Theory (DFT) with B3LYP hybrid exchange-correlation functional and 3-21G basis set and semi-empirical methods (PM3) were used to calculate the energies (total energy, binding energy (Eb), molecular orbital energy (EHOMO-ELUMO), heat of formation (∆Hf)) and vibrational spectra for some Tellurium (IV) compounds containing cycloctadienyl group which can use as ligands with some transition metals or essential metals of periodic table at optimized geometrical structures.
Soil‐microbial response to sugarcane filter cake and biogenic waste compost

An incubation experiment was carried out to examine the N-immobilizing effect of sugarcane filter cake (C : N = 12.4) and to prove whether mixing it with compost (C : N = 10.5) has any synergistic effects on C and N mineralization after incorporation into the soil. Approximately 19% of the compost-C added and 37% of the filter cake-C were evolved as CO 2 , assuming that the amendments had no effects on the decomposition of soil organic C. However, only 28% of the added filter cake was lost according to the total-C and δ 13 C values. Filter cake and compost contained initially significant concentrations of inorganic N, which was nearly completely immobilized between day 7 and 14 of the incubation in most cases. After day 14, N remineralization occurred at an average rate of 0.73 μg N (g soil)-1 d-1 in most amendment treatments, paralleling the N mineralization rate of the nonamended control without significant difference. No significant net N mineralization from the amendment N occurred in any of the amendment treatments in comparison to the control. The addition of compost and filter cake resulted in a linear increase in microbial biomass C with increasing amounts of C added. This increase was not affected by differences in substrate quality, especially the three times larger content of K 2 SO 4 -extractable organic C in the sugarcane filter cake. In most amendment treatments, microbial biomass C and biomass N increased until the end of the incubation. No synergistic effects could be observed in the mixture treatments of compost and sugarcane filter cake.
Effects of Brominating Matrimid Polyimide on the Physical and Gas Transport Properties of Derived Carbon Membranes

Bromination modification was initially carried out on Matrimid polyimide before undergoing carbonation to produce carbon membranes. Compared with unmodified Matrimid, brominated Matrimid shows lower chain flexibility, which is demonstrated by increased glass transition temperatures and molecular simulation results. Additionally, an increase in space between polymer chains was supported by fractional free volume (FFV) and d-spacing measurements. The improvement of chain rigidity of polyimide precursors serves to strengthen the membrane morphology during the production of carbon membranes. Thermal gravimetric analysis indicates that the thermal stability of polyimide decreases after bromination. The lower thermal stability and higher FFV value of brominated Matrimid result in higher gas permeability of carbon membranes pyrolyzed at a low pyrolysis temperature, while the selectivity remained competitive to those pyrolyzed from the original Matrimid precursor under the same conditions. However, the gas permea.
Facteurs décisionnels dans la gestion des ressources hydriques par les éleveurs et les agro-éleveurs dans une zone semi-aride du Burkina-Faso

Une étude a été conduite dans une zone semiaride du Burkina Faso, pour identifier les facteurs qui influencent éleveurs immigrés et agro-éleveurs autochtones dans la gestion des ressources hydriques. Les résultats de l’étude montrent que le pâturage, l’eau et d’autres facteurs secondaires influencent le choix de l’éleveur lors de son installation dans une zone. Le village et l’origine géographique des producteurs peuvent influencer l’utilisation des différents types de points d’eau. L’étude montre, aussi, que la facilité d’accès ou d’exhaure et la proximité influencent également leurs choix. Ces facteurs expliquent pourquoi éleveurs et agro-éleveurs utilisent fréquemment (56 à 94%) les eaux de surface pour abreuver les bovins et les ovins, et les forages (41,1 à 76,9%) pour abreuver les ovins et les caprins. Les puits sont utilisés de façon marginale. Les eaux de surface exercent une attraction, sur les deux catégories de producteurs, dans un rayon de 4 km. Les facteurs qui déterminent les comportements des éleveurs et agro-éleveurs dans la gestion des ressources hydriques sont similaires: le type de point d’eau, la distance et l’espèce animale influencent leurs choix. Cependant, les deux groupes présentent des différences dans les niveaux de fréquentation des points d’eau.

Adsorption of basic red 9 onto activated carbon derived from immature cotton seeds: isotherm studies and error analysis

AbstractThe activated carbon produced from immature cotton seeds via sulphuric acid activation was utilized for adsorption of the basic red 9 from the aqueous solution. Adsorbent possessed a larger surface area (495.96 m2/g), methylene blue number (42) and iodine number (510). The process parameters of the sorption system, such as pH of the solution (2–12), temperature (20–40°C) agitation time (1–5 h) and initial BR9 concentration (50–250 mg/l), were studied to understand their effects on BR9 removal. The optimized parameters are found to be pH: 12, temperature: 40°C, agitation time: 3 h and initial concentration: 150 mg/l. The experimental equilibrium data were analysed using a single-parameter model (Henry’s law), six two-parameter models (Langmuir, Freundlich, Temkin, Dubinin–Radushkevich, Smith, and Javanovic), eleven three-parameter models (Redlich–Peterson, Sips, Toth, Hill, Khan, Brunauer–Emmett–Teller (BET), Fritz–Schluender-III, Vieth–Sladek, Radke–Prausnitz, Brouers–Sotolongo, and Unilin), five .

X-ray photoemission spectroscopy study of UV/ozone oxidation of Au under ultrahigh vacuum conditions

(111) textured Au films were oxidized under UHV conditions by exposing them to UV radiation and ozone. The Au films were characterized by x-ray photoelectron spectroscopy. The gold surface becomes heterogeneous upon oxidation: approximately 0.8 monolayer (ML) of the adsorbed oxygen is present as chemisorbed species. The rest of the adsorbed oxygen forms, on the average, a few ML thick gold oxide with a stoichiometry close to Au2O3. Both the oxide and the chemisorbed oxygen disappear slowly when heated to 150 °C. During isothermal decomposition at 200 °C, the oxide is transformed to chemisorbed oxygen prior to desorption. Both the chemisorbed oxygen and the gold oxide can be removed by rinsing with water. The surface is hydrophilic after the rinse. When contaminated gold films are exposed to UV/ozone, impurity oxides appear at higher binding energies than the binding energies of oxygen on clean gold samples. The impurity oxides are thermally much more stable than Au2O3.
Bio-adsorption of triadimenol pesticide from aqueous solutions using activated sludge of dairy plants

AbstractIn the present study, activated sludge has been utilized for the removal of triadimenol pesticide from water. The maximum adsorption capacity was 42.9 mg triadimenol per gram activated sludge obtained at 298 K. The equilibrium data were fitted to Langmuir Freundlich models and it was found that Freundlich model best fit these data with regression coefficient R2 = 0.947. The kinetic data showed that the rate of triadimenol adsorption is increased with increasing the initial concentration and mixing speed, while decreased with increasing temperature. The two-resistance mass transfer model based on the film resistance homogeneous solid-phase diffusion was used to fit the experimental data. A computer program has been developed to estimate the theoretical concentration–time- dependent curves and to compare them with the experimental curves by means of the best-fit approach. The model predicts that the external mass transfer coefficient kf was affected by varying the initial triadimenol concentration, .
A Comprehensive Overview of Celastrus paniculatus Seed Oil Intended for the Management of Human Ailments

Celastrus paniculatus belonging to the family Celastraceae generally known as the black oil plant or Malkangani or Jyotishmati. The scrambling through a yellowish corky bark, climbing poly gamodioecious category of shrub requires support to climbs up and distributed almost all over India at the altitude of 2000 m. The seeds are also reported as anxiolytic and anticonvulsant properties, while the root and its bark considered being useful for the treatment of malaria, cancer, and brain-tonic. Plant of Jyotishmati are broadly used in the Ayurvedic system of the medicine to cure many diseases such as; appetizer, aphrodisiac, arthritis, asthma, antipyretic, amenorrhea, anti-inflammatory, acrid, arthralgia, beriberi, cardiotonic, diuretic, diaphoretic, depression, emollient, skin-diseases, paralysis, thermogenic, intellect-promoting, emetic, expectorant, leprosy, leucoderma, cephalalgia, nephropathy, abdominal disorders, sores abortifacient, and treatment of the snake bite. These plants are naturally used in the treatment of vaginal discharge, a sensation of burning, blood purification after delivery, menstruation cycle, and abortion. The seed oil contains steroid alkaloids and bright natural coloring matter, celapanine, celapanigine, celapagine, celastrine, and paniculatine are the important alkaloids. It contains the fatty acid it’s in founding; oleic acid (54.42%), palmitic acid (20.0%), linoleic acid (15.51%), and stearic acid (4.18%). The sesquiterpene alkaloids are derived from a new sesquiterpene (celapanol) which is alternately esterified by acetic, benzoic, nicotinic, and β- furoic acids.
Isothermal compressibility of supercooled water and evidence for a thermodynamic singularity at −45°C

Using a capillary technique for small samples, the isothermal compressibility κ T of water has been measured to −26°C. Accelerating increases of κ T at the lower temperatures can be described by an expression of the form κ T =Aeγ [where e= (T−T s )/T s ], which is known to describe anomalies encountered in the vicinity of a thermodynamic singularity located at T s . The implication that the thermodynamic and certain other properties of water at lower temperatures may be decomposed into a normal component and an anomalous component which diverges at T s =−45°C is supported by analysis of numerous other thermodynamic and relaxation data which extend into the supercooled regime. The anomalous characteristics are shown to originate primarily in the sensitivity of the volume to temperature changes, suggesting a geometrical basis for the cooperative behavior. The singularity at T s =−45°C may be a lambda transition associated with the cooperative formation of an open hydrogen‐bonded network, but the near coincidence of T s with the experimental homogeneous nucleation temperature suggests, as an alternative, that T s may correspond to the limit of mechanical stability for the supercooled liquid phase.
Fluoride and nitrate in groundwater of south-western Punjab, India—occurrence, distribution and statistical analysis

AbstractPrevalence of fluoride and nitrate in groundwater has become major concern due to their potential environmental related health impacts. High fluoride and nitrate concentrations have been reported from many parts of rural southwestern Punjab causing serious health threats to the inhabitants. The present study is focussed on evaluating the recent status of fluoride and nitrate contamination of drinking water sources from Ferozepur, Faridkot, and Bathinda districts of Punjab. The sampling sites were selected after comprehensive surveying and preliminary analysis of the data collected through questionnaire. Other physico-chemical parameters analyzed were the pH, TDS, electrical conductivity, phosphate concentration along with depth, and age of source. Findings showed that 59 and 95% groundwater samples were found to have fluoride and nitrate content, respectively, beyond permissible limits (WHO). High fluoride concentration up to 10.6 mg/L and nitrate concentration up to 90 mg/L in drinking water is o.
