The Modification of Carbon Included Polyethylene Surface by Plasma Treatment for Metallizing Using a Low Pressure RF Discharge Plasma

Abstract Surface modification of the carbon included polyethylene (semi-conductive PE) surface for metallizing using a low pressure RF discharge plasma has been carried out. The contact angle was used as a measure of the wettability of the PE surface. The roughness and the chemical bondings in PE surface layer were analized by DFM and XPS, respectively. Typical results show that the contact angle decreases from approximately 94° to below 10° after several minutes' treatment and recovers to a saturation value when it was put open to the air after treatment. The saturation value of the contact angle is smaller as the gas pressure for treatment is higher and the treatment time is longer but all are below approximately 60° which is still smaller than that of untreated. DFM and XPS results show that the surface roughness and the bondings C-O and C=O in the PE surface layer also increase with increasing the treatment time and seem to be responsible for improving the hydrophilic property of PE. After pretreatment process, nickel was coated on the PE sheet by electrodeposition method and a good adhesion between the nickel layer and the PE surface compared with that of untreated was obtained.
Morphophysiological traits of soybean leaflets and their relationship with crop agronomic performance

Soybean genotypes have distinct morphophysiological traits, which may influence the crop agronomic performance. The aim of this work was to evaluate the productive parameters of three contrasting soybean genotypes for leaf morphophysiological traits. The experiment was carried out at in a typical Distroferric Red Latosol, located at latitude 25º41'52" S and longitude 53º03'94" W; in the 2015/16 (CY1) and 2016/17 (CY2) seasons. The genotypes tested were: BS 2601 RR® (lanceolate and smaller leaflets); NS 6006 IPRO® (triangular and intermediate leaflets) and homozygous lineage CI 21 IPRO® (oval and larger leaflets). The gas exchange, chlorophyll index, leaf area, leaflet length and width, and petiolulus length were evaluated when plants of each genotype were at the beginning of flowering. At harvest, the variables analyzed were: first pod insertion, plant height, number of pods and grains per plant, grains per pod, mass of one thousand grains and grain yield. The design used was randomized blocks with four replicates. Photosynthesis per leaf area unit was higher in CY2, and is related to greater stomatal conductance, higher chlorophyll index, lower transpiration and lower leaf area of plants. The lanceolate leaf cultivar showed higher grain yield due to the higher number of grains and the greater mass of these grains in the two crop years. In addition, it was the one that obtained lower leaf area and lower transpiration. The cultivar NS 6006 presented greater productive stability, but this trait does not confer greater productive potential.
The Influence of Trust on The Intention to Perform electronic Word-of-Mouth (eWOM) and Purchase Intention Among S-Commerce Users

Trust is outlined as one of the key components to ensure the customer's continued online transactions. However, previous studies on the influence of trust in the context of S-commerce, especially in Malaysia, are still limited. Therefore, this study aimed to determine the influence of trust on the intention to perform electronic Word-of-Mouth (eWOM) and purchase intention among Scommerce users. This study uses a quantitative approach in the form of a survey of samples. Exploratory Factor Analysis (EFA) and Cronbach’s alpha analysis of pilot study data indicate that item validity and instrument reliability are satisfactory. The actual study involved 250 Facebook users following the company's fan page. The study data were analyzed using Structural Equation Modelling (SEM) analysis with Analysis Moment of Structure (AMOS) software. The findings show that the measurement model is suitable for hypothesis testing. Structural model tests show goodness of fit and prove that there are four hypotheses that are significant and positively related and one hypothesis that is not significant and negatively related. The findings show that there is a positive and significant relationship between S-commerce trust and company trust, S-trade belief with the intention to do electronic Word-of-Mouth (eWOM), the company's belief with the intention of doing electronic Word-of-Mouth (eWOM) and the positive and significant relationship between the intention to perform electronic Word-of-Mouth (eWOM) with the purchase intention. However, there is a negative and insignificant relationship between S-trade trust and purchase intention. The results of this study are also expected to provide useful input to other researchers to continue their research on trust in the context of S-commerce. These insights can also serve as references in the development of more affective and dynamic online business modules to assist entrepreneurs in building customer trust.
Permeation characteristics of hydrogen through palladium membranes in binary and ternary gas mixtures

The permeances of two palladium (Pd) membranes in pure H2, binary and ternary gas mixtures are investigated experimentally. With 10% of gas impurities (N2, CO2, or CO) in H2, the profiles of dimensionless permeance suggest that H2 permeation rate is lessened by approximately 50% to 90%, and the permeance reduced by the gas impurities is ranked as CO > CO2 > N2. By introducing a parameter of permeance resistance, which is the reciprocal of permeance, the permeance resistance in a ternary gas mixture can be predicted from the summation of individual permeance resistances in binary gas mixtures, revealing no synergistic effect exhibited from the interaction of contaminants. At least 75% and up to 100% of H2 in the gas mixtures can be recovered in the membrane system, and the maximum H2 recovery develops at the H2 partial pressure difference of 2 or 3 atm. In the Arrhenius‐type equation describing the relationship between the permeance and temperature, the activation energy is between approximately 2 and 18 kJ mole−1. In general, the permeances of the membranes in gas mixtures, especially in ternary gas mixtures, are more sensitive to temperature when compared with those in pure H2, stemming from lower activation energy exhibited.

Extraction and Concentration Effect on Dimerization of Copper(II) Caprate

ABSTARCT Extraction of copper(II) with capric acid in chloroform was investigated at 25°C and aqueous ionic strength of 0.33 mol dm–3 (Na2SO4). The composition of the complex extracted was determined using the slope analysis method. Copper(II) complex exists as a monomeric species CuL2.2HL in the lower concentration range of capric acid and a dimeric species (CuL2.HL)2 in the higher concentration range, while both monomer and dimer were extracted at a total capric acid concentration of 0.1–0.2 mol dm–3. Extraction and dimerization constants of the above species were also determined. UV-Visible and FT-IR spectroscopy have also been applied for the study of the ligand and their copper(II) species. Electronic spectrum of the organometallic complexes suggests the octahedral geometry.
Analyst Underreaction and the Post‐Forecast Revision Drift

The post‐forecast revision drift (PFRD), the phenomenon of delayed stock price reactions to analyst forecast revisions, is a well‐documented market anomaly. Prior research attributes PFRD to underreaction by investors to analyst forecast revisions. This study investigates the role of the analyst forecast revision process itself in the PFRD anomaly. Using a large sample of US firms, we confirm prior findings of a positive serial correlation (momentum) in individual analysts’ revisions to their earnings forecasts and, based on both indirect and direct tests, document a positive association between this momentum and PFRD. Further analyses reveal that both the forecast revision momentum and PFRD vary in similar ways with respect to the nature of the news driving the revisions and the information environment. Collectively, our findings show that underreaction by individual analysts in the forecast revision process is an important contributor to the PFRD phenomenon.
Mesoporous Ni-doped MnCo2O4 hollow nanotubes as an anode material for sodium ion batteries with ultralong life and pseudocapacitive mechanism

Mesoporous Ni-doped MnCo2O4 hollow nanotubes (denoted as MCNO-HNTs) are successfully prepared through simple single-nozzle electrospinning combined with thermal treatment. MCNO-HNTs obviously exhibit a hollow structure and are assembled by a lot of small nanoparticles. When used as an anode material for sodium-ion batteries (SIBs), this electrode exhibits remarkable capacity retention of 81% at 1 A g−1 even after 11 000 cycles. The outstanding electrochemical performance can be attributed to the unique hollow mesoporous structure that alleviates stress caused by large volume changes, suppresses the agglomeration of the pulverized nanoparticles, and facilitates the transfer of electrons and electrolyte ions during prolonged cycling. Furthermore, the pseudocapacitive behavior of this material also effectively improves the electrochemical reaction kinetics. Therefore, due to the simple single-nozzle electrospinning technique and high electrochemical performance, mesoporous MCNO-HNTs have great potential as an anode material for rechargeable SIBs.

Treatment of Wine Distillery Waste in UASB Systems – Feasibility, Alkalinity Requirements and pH Control

Grape wine distillery waste developed a pelletised sludge bed in a UASB system. Product formation along the line of flow in the pelletised bed was similar to that when treating a pure carbohydrate, apple juice waste. Pelletised sludge production was about 0.14 mgVSS/mgCOD removed (as against 0.42 mgVSS/mgCOD removed for apple juice waste), indicating a low influent COD carbohydrate fraction. The pellets were not as compact as with apple juice waste and were smaller ( 6.6. Recycle ratios as high as 33:1, reducing the base influent COD of 27 000 mg/l to a CODe of 790 mg/l, did not adversely affect COD removal. No nitrogen, phosphate or trace element supplementation was required. COD removal was greater than 94 percent for COD loading rates up to the maximum of 15 kg/(m3 sludge bed.d); the maximum COD loading rate was fixed by gas lifting pellets in to the settling section, not by process failure.
Solid State Stability and Preformulation Studies for Acetylcholinesterase Inhibitor Drug Tacrine

In this paper, the acetylcholinesterase inhibitor drug tacrine was investigated by two complementary instrumental techniques, namely infrared spectroscopy and thermal analysis, as pure drug and in solid binary mixtures with nine excipients frequently used in the pharmaceutical industry, namely starch, sodium carboxymethyl cellulose, polyvinylpyrrolidone K30, fumed silica (Aerosil), talc, anhydrous lactose, magnesium stearate, mannitol and calcium lactate pentahydrate. The corroboration of obtained data by the two complementary methods confirmed the incompatibility of this drug with anhydrous lactose, mannitol, magnesium stearate and calcium lactate under both ambient conditions and thermal stress, and thermally induced interactions between tacrine and silica. In the development of new generic solid formulations, four of the investigated excipients (i.e., starch, sodium carboxymethyl cellulose, polyvinylpyrrolidone K30 and talc) can be used, since they are compatible with tacrine under ambient conditions as well as under thermal stress.
Character association and path coefficient analysis studies on yield and yield attributing characters in Turmeric (Curcuma longa L.)

The Correlation and path analysis was studied for fresh rhizome yield per hectare and its component characters in 12 diverse genotypes of turmeric during Kharif season of 2014-15, 2015-16 and 2016-17 at Horticultural research Station, Chintapalli. The data recorded on different characters were subjected to work out correlation and path analysis to investigate the association, direct and indirect contribution of various characters on fresh rhizome yield per hectare. The resulted indicated that the strong positive genotypic correlation of plant height and yield per plant with yield per hectare. The dry recovery had a significant positive correlation with plant height, leaf length and leaf area while the significant negative correlation with the number of tillers per plant. The path analysis study revealed that the yield per plant the most important yield per hectare determinant followed by leaf length and leaf area is the another most important yield determinant thus, these characters should be given importance in selection programmes for yield improvement in turmeric.
Assessment of allelopathic potential of Dalbergia cochinchinensis Pierre and its growth inhibitory substance

In forestry systems, many types of forest trees possess allelopathic properties and release a wide variety of allelochemicals that influence the growth and development of surrounding species. Dalbergia cochinchinensis, a forest tree distributed in Southeast Asia, is reputed to possess several biological properties and contain several secondary compounds. However, there have been no studies on the allelopathy of D. cochinchinensis. Therefore, D. cochinchinensis leaf extracts were examined for allelopathic potential. The present study showed that D. cochinchinensis extracts significantly inhibited the seedling growth of six test plant species: timothy, Italian ryegrass, barnyard grass, cress, alfalfa, and lettuce. Concentrations of the D. cochinchinensis extracts negatively correlated with the shoot length (r = −0.50 to −0.89) and root length (r = −0.65 to −0.89) of all the test plant species. The extracts were then purified using several chromatographic steps and the growth inhibitory substance was isolated. The chemical structure of the substance was identified through spectroscopic analysis as 3,4-dihydroxybenzoic acid (protocatechuic acid). Protocatechuic acid at a concentration higher than 3 mM significantly inhibited the growth of cress seedlings, whereas barnyard grass seedlings were inhibited at concentrations higher than 0.3 mM. As the protocatechuic acid concentration increased, the seedling growth of cress and barnyard grass was significantly reduced. I50 values showed the effectiveness of protocatechuic acid against both test plant species was apparently greater on root growth than shoot growth. Results of this study suggest that protocatechuic acid isolated from D. cochinchinensis might be responsible for its inhibitory effects.
Vibration characteristics of tractor seat cushion materials

Operators of agricultural machinery are exposed to an extensive range of indirect vibrations through the seats, which gradually causes chronic damages. One of the ways to reduce the vibrations imposed on the operators is to use appropriate materials in tractor seat cushion. The present study was carried out in order to select appropriate foam or sponge and investigate different factors in reducing vibrations imposed on operator’s body so as to promote drivers health and enhance their working efficiency. Vibration experiments were performed at different accelerations on foam and sponge materials at different thicknesses and densities for different occupant masses, and the input and output acceleration signals were recorded and analyzed. Using the analysis of variance, analysis of the mean squares of the input and output acceleration, the type of material used in the seat cushion and the effect of different factors on them were investigated. The results showed that in reducing vibrations, sponge for mass of 90 kg and more and foam for mass of 75 kg and less were more efficient. The sponge was also suitable for acceleration of excitation above 6 ms-2and foam for acceleration of excitation above 3 ms-2 and below. Therefore, according to the working conditions of agricultural machines and anthropometric characteristics of Iranian drivers and the appropriate suitable thickness of the seat cushion (6-8 cm), it is recommended that their seat cushion be made of a combination of foam and sponge with high density and thickness of 8 cm.

Synthesis, Properties, and Structures of Low-melting Tetraisocyanato-cobaltate(II)-based Ionic Liquids

A series of new ionic liquids of the formula Ax[CoII(NCO)4] with the [CoII(NCO)4]2 anion and nitrogen-based organic cations was synthesized. The single crystal structures of all compounds were determined by X-ray diffraction and reveal for all cases the existence of discrete ions. The magnetic behavior at room temperature is paramagnetic resulting from the high-spin tetrahedrally coordinated CoII ions. Melting points or glass transition temperatures are found in the range of ionic liquids for some of the compounds with singly charged cations, and above 100 °C for all compounds with doubly charged cations and the [PPN]+ salt. Each compound has been characterized by elemental analysis, NMR-, IR-, and UV/Vis- spectroscopy. Measurements of the density, dynamic viscosity, conductivity and surface tension for the low melting substance [EMIm]2[Co(NCO)4] show, that they differ slightly but are generally comparable to the corresponding values of the isothiocyanato complexes.
Porous nanostructure controls kinetics, disposition and self-assembly structure of lipid digestion products

A combination of proton nuclear magnetic resonance (1H NMR) and synchrotron small-angle X-ray scattering (sSAXS) was used to discriminate the speciation and structure evolution of lipolysis products for submicron lipid droplets and lipid loaded in porous silica particles. The free fatty acid (FFA)-to-glyceride ratio was controlled by confining medium-chain length triglycerides (MCT) in porous silica particles, which influenced the colloidal self-assembly structures formed within the lipolysis media. FFA and glycerides released during hydrolysis formed highly geometrically organised structures in a time-dependent manner. Structural transitions from coexisting emulsion droplets and micelles to lamellar structures, and finally to inverse hexagonal phase were observed during the digestion of lipid droplets. In contrast, when hosted in porous silica particles the digestion of lipids resulted in the self-assembly of a lamellar phase that was independent of digestion time. The evolution of structure during lipid digestion was dependent on lipolysis kinetics and the relative concentration of FFA to glycerides, which highlights important implications for the controlled delivery and absorption of lipophilic bioactives.

Domar, Expectations, and Growth Stabilization

Evsey Domar investigated in the 1940s the implementation of growth stabilization policy under the assumption that policy makers and businessmen alike believed his theoretical growth model. Economic policy was supposed to work merely through the impact of its announcement on expectations. He claimed that confident expectations, generated by government’s assurance of future growth through fiscal policy, would induce private investment decisions in a scale that would bring about the required growth rate and by that justify the expectations, without putting the guarantee to test. Domar’s policy framework contrasts with the policy-ineffectiveness proposition of New Classical macroeconomics advanced in the 1970s. Domar’s stabilization plan is discussed in detail in the context of his growth model, together with similar ideas put forward by Roy Harrod, as the latter modified aspects of his original growth model, and critical reactions by Alvin Hansen.
