Drivers of organizational commitment and job satisfaction among lodging industry employees.

This study focused primarily on determining the relationship and influence of job satisfaction dimensions on organisational commitment among lodging employees. This study employed a quantitative research design and data were collected from 290 front-line employees of the Department of Tourism’s accredited lodging facilities in South Cotabato Province, Sarangani Province, and General Santos City (SOCSARGEN), Philippines area using the convenience sampling. Data analysis showed that employee pay, promotion opportunities, supervision, fringe benefits, contingent rewards, relationship with co-workers, nature of work, and communication were among the dimensions of employee job satisfaction that were positively related with organisational commitment. Operating procedures showed a negative relationship with organisational commitment. Only the nature of work, promotion opportunities, and relationships with co-workers, operating procedures, and supervision from the facets of employee job satisfaction posted as significant predictors of organisational commitment.
Multi‐objective optimization for diffuse pollution control at zero cost

Agricultural best management practices (BMPs) are gaining ground as a means of mitigating diffuse nutrient pollution of surface waters in agricultural catchments; however, their cost‐effectiveness depends on the location‐specific characteristics of the land on which they are applied. To identify acceptable catchment management solutions with respect to environmental and economic objectives, a decision support tool (DST) is used in this study. The DST integrates the river basin soil and water assessment tool (SWAT) model that serves as the nonpoint source pollution estimator into an optimization framework consisting of a multi‐objective genetic algorithm that searches for optimal selection and location of BMPs in the landscape. A three‐objective optimization problem has been previously solved for the Arachtos catchment in western Greece including the implementation costs of several types of BMPs such as nutrient application, crop, soil and livestock management and total annual diffuse losses of total phosphorus (TP) and nitrate‐nitrogen (NO3‐N) from land to surface waters. In the present study, a solution of negligible total cost for the whole catchment was selected from optimal two‐dimensional trade‐off curves of cost‐TP and cost‐NO3‐N, aiming to complement previously analysed management options and further enhance decision‐making in this catchment. The zero cost solution led to 30 and 20% reductions in TP and NO3‐N river concentrations, respectively, corresponding to contour cultivation without tillage in corn, fertilizer management in alfalfa as well as livestock and manure management along with the establishment of filter strips at the edge of some corn and pastureland fields. The proposed methodology enabled the identification of a low cost, and possibly more favourable, compared to previous findings, combination of BMPs that ensures good quality of river water. It helps to provide the basis for sustainable land‐use planning and management in large agricultural landscapes, thus aiding decision‐making and cost‐effective implementation of Environmental Directives.
Infestação por bicho-mineiro e teores foliares de açúcares solúveis totais e proteína em cafeeiros orgânicos

O experimento foi instalado em agosto de 2004 em uma lavoura cafeeira, cultivar ‘Catuai amarelo’, espacamento 4,0 x 0,7 m e idade de 6 anos), no primeiro ano de transicao agroecologica. Empregou-se o delineamento latice balanceado 4x4, com cinco repeticoes em fatorial 3x2x2, mais quatro tratamentos adicionais. Foram testados dezesseis tratamentos de acordo com as normas de agricultura orgânica: tres adubos orgânicos (farelo de mamona, o esterco bovino, a cama de aviario), com ou sem palha de cafe em cobertura aplicada sobre os adubos; com ou sem adubacao verde com feijao-guandu nas entrelinhas dos cafeeiros, e adubacao foliar com biofertilizante para todos os tratamentos orgânicos. Os tratamentos adicionais testaram o efeito do uso de carvao e farinha de rocha em conjunto com adubos orgânicos e somente a utilizacao de palha de cafe e adubacao verde como fertilizantes. O manejo convencional (testemunha) utilizou sulfato de amonio, cloreto de potassio e adubacao foliar convencional. Foi avaliada a interacao entre o comportamento do bicho mineiro (Leucoptera coffeella) sobre o teor de acucares soluveis totais e proteina na folha do cafeeiro. Constatou-se que a adubacao orgânica afeta a producao de acucares soluveis totais na folha do cafeeiro, ja a adubacao convencional necessita de mais estudos em solos tropicais. O farelo de mamona promove um menor acumulo de acucares soluveis totais na folha, o que possivelmente concorre para um aumento da resistencia da planta ao bicho-mineiro.
Synthesis and Crystal Structure of a Mononuclear Zn(II) Complex with Tridentate Schiff Base,Zn(C_(12)H_(18)N_2O)(NCS)_2

The title complex Zn(HL)(NCS)2 (C14H18N4OS2Zn, Mr = 387.81, HL = N-(3-di-methyl-aminopropyl)-salicylaldimine) has been synthesized by the reaction of ZnSO4·7H2O with the Schiff base N-(3-dimethylaminopropyl)-salicylaldimine derived from the condensation reaction of 3-dimethylamino-1-propylamine with salicyladehyde. It crystallizes in the monoclinic system, space group P21/n with a = 9.8360(8), b = 14.930(1), c = 12.277(1) , ( = 101.455(2)o, V = 1767.0(3) 3, Z = 4, F(000) = 800, Dc = 1.458 g/cm3 and ((MoK() = 1.631 mm-1. The structure was refined to R = 0.0463 and wR = 0.1065 for 2681 observed reflections (I 2((I)). Crystal analyses revealed that the Zn(II) atom is coordinated by two nitrogen atoms of two NCS-, and an oxygen atom as well as a nitrogen atom of amine from the neutral Schiff base ligand of N-(3-dimethyl-aminopropyl)-sali-cylaldimine to give a distorted tetrahedral geometry.
Discriminant analysis for classification of colonic tissue autofluorescence spectra

This study evaluates the potential of a discriminant analysis to classify colonic mucosa from autofluorescence spectral characteristics. With 337 nm excitation, the autofluorescence spectra of colonic tissues were measured using a FLS920 spectrofluorimeter. Principal component analysis (PCA) combined with Fisher's discriminant analysis was performed for tissue classification. As a result, the sensitivity and specificity of the discriminant analysis is 92.3% and 90.5%, respectively. The results suggest the relative concentrations of collagen and nicotinamide adenine dinucleotide (NADH) are the potential diagnostic biomarkers for colonic tissue classification using autofluorescence spectroscopy, and the discriminant analysis based on PCA is useful to differentiate adenocarcinoma from normal tissue.
Influence of sputtering conditions on microstructure and mechanical properties of Zr–Si–N films prepared by radio-frequency-reactive sputtering

ZrN and ZrSiN films were prepared in an rf-sputtering apparatus which has a pair of targets facing each other (referred to as the facing target-type rf sputtering). In order to investigate the influence of substrate temperature on the structure and mechanical properties of Zr–Si–N films, the substrate temperature during the deposition was changed from 373 K to 673 K. Only one phase with a cubic B1 NaCl structure, typical for ZrN, can be clearly identified in all Zr–Si–N films in this study. Increasing substrate temperature can improve crystalline quality in all Zr–Si–N films in this study. Grain sizes of all Zr–Si–N thin films, despite the Si content, increase linearly with increasing substrate temperature. However, the grain growth speed with increasing substrate temperature in a pure ZrN thin film is much faster than that in Zr–Si–N thin films, because Si atom occupation of interstitial sites tends to lock diffusion paths and thus stabilize the structure. The hardness of Zr–Si–N films with low Si conten.
Gas Flow and Particle Transport and Deposition in a Pilot-Scale Furnace

The present work describes a computer simulation study of gas flow and particle transport and deposition in a pilot-scale furnace with cooling system. The Gambit code is used to generate the geometry and the computational grid. An unstructured mesh is generated for the pilot-scale boiler. The FLUENT code is used for evaluating the gas mean velocity, turbulence fluctuation energy, and mean pressure, as well as temperature fields and chemical species concentrations. The particle equation of motion includes the nonlinear drag, gravity, Brownian, lift, and thermophoretic forces. The gas velocity and thermal conditions in the furnace are studied. Ensembles of particle trajectories are generated and statistically analyzed. Particle deposition rates on different walls are evaluated, and the effect of particle size is studied.
Organo-Modification of Mesoporous SBA-15 with Chiral Diacid and its Utilization for the Preparation of L-Phenylalanine-Based Poly(amide-imide) Nanocomposites

In this study ultrasonic irradiation has been proposed for organo-modification of SBA-15 with N,N′-(pyromellitoyl)-bis-L-phenylalanine. Chiral poly(amide-imide) (PAI) was synthesized by the direct polymerization of L-chiral diacid and 4,4-diaminodiphenyle sulfone in molten tetrabutylammonium bromide. Different nanocomposites (NCs) of modified SBA-15 and chiral PAI were synthesized by solution intercalation method under ultrasonic irradiation. The structures and morphology of the hybrids were investigated by different techniques. The NCs showed an improvement in the thermal properties in comparison with the neat PAI. Transmission electron microscopy images show well-ordered hexagonal arrays of mesopores SBA and the average distances between neighboring pores is around 3–5 nm. GRAPHICAL ABSTRACT
Crystal structure of potassium manganese(II) gallium phosphate hydrate, K[MnGa2(PO4)3(H2O)2]

Ga2H4KMnO14P3, monoclinic, C12/c1 (no. 15), a = 13.534(1) Å, b = 10.179(1) Å, c = 8.8703(7) Å, * = 107.948(1)°, V = 1162.5 Å, Z = 4, Rgt(F) = 0.021, wRref(F ) = 0.056, T = 298 K. Source of material The title compound was synthesized from a mixture of K2B4O7 · 4H2O (0.1528 g), Ga2O3 (0.0941 g), KOH (0.2954 g), MnCO3 (0.2312 g), H3PO4 (0.5 mL) and H2O (5 mL) in the molar ratio of 5 : 5 : 5 : 20 : 8 : 280. This mixture was sealed in a 25 mL Teflonlined stainless steel vessel, and heated at 200 °C for about 10 days under autogenous pressure, then cooled to room temperature. The resulting colorless columnar crystals were collected and dried in air at ambient temperature. The TG analysis shows that the title compound has one step of mass loss between 81 °C and 600 °C. The total weight loss is 6.53 %, which corresponds to the loss of two water molecules, and can be compared with a calculated value of 6.24 %. FT-IR data are available in the CIF. Discussion Since the discovery of the microporous aluminum phosphates, the hydrothermal synthesis and structural characterization of new open-framework solids templated by organic molecules have attracted considerable attention. In the past several decades, many metal and non-metal phosphates with open-framework structures have been synthesized owing to their rich structural chemistry and the potential applications in ion exchange, adsorption, separation and catalysis [1]. To date, a number of compounds MeGaPO4 (Me = V, Mn, Fe, Co and Zn) have been prepared, the majority of which contain MO4 (M = Me or Ga) and PO4 units. To our knowledge, however, only three examples of manganese(II)substituted gallium phosphates have been reported: (C3N2H5)8[Mn8Ga16P24O96] [2], [C6N2H14][MnGa(HPO4)2 (PO4)] [3], NH4[MnGa2(PO4)3(H2O)2] [4]. The crystal structure of the title compound is similar to that of NH4[CoGa2(PO4)3(H2O)2] [5], K[NiGa2(PO4)3(H2O)2] [6], and NH4[MeGa2(PO4)3(H2O)2] (Me = Mn, Fe, Ni) [7]. It consists of K cations and [MnGa2(PO4)3(H2O)2] anions in a 1 : 1 ratio. In the anion, there are two crystallographically distinct phosphorus sites, both of which have approximately regular tetrahedral environment. The Ga atoms occur in GaO5 units with distorted trigonal bipyramidal shape and the Mn atoms in MnO4(OH2)2 distorted octahedra. The GaO5, MnO6 and PO4 units are linked together through common edges and vertexes to give a manganese-gallophosphate framework of the composit ion [MnGa2(PO4)3 (H2O)2] (figure, top). The Ga—O bond lengthes are from 1.840(2) Å to 2.010(2) Å (average 1.905 Å) and the Z. Kristallogr.

Kinetics of MB degradation and effect of pH on the photocatalytic activity of MIn2O4 (M = Ca, Sr, Ba) under visible light irradiation

Degradation of Methylene Blue (MB) on MIn2O4 (M = Ca, Sr, Ba) semiconductors was observed and the analysis of the products confirmed that MB was decomposed other than simply bleached on these photocatalysts under visible light irradiation. The activity order under visible light irradiation was CaIn2O4 > SrIn2O4 > BaIn2O4. The reaction kinetics of MB degradation on MIn2O4 was investigated, suggesting that these reactions followed approximately first-order kinetics. Furthermore, the effects of pH value of the solution on the photocatalytic properties of these materials were observed in detail, which indicated that the decomposition efficiency of MB was the highest in the alkaline solution and the lowest in the acidic solution on all of the photocatalysts.
Electronic structure of layered ferroelectric high-k titanate La2Ti2O7

The electronic structure of binary titanate La2Ti2O7 has been studied by x-ray photoelectron spectroscopy. Spectral features of valence band and all constituent element core levels have been considered. The Auger parameters of titanium and oxygen in La2Ti2O7 are determined as αTi = 872.4 and αO = 1042.3 eV. Chemical bonding effects have been discussed with binding energy (BE) differences ΔTi = (BE O 1s − BE Ti 2p3/2) = 71.6 eV and ΔLa = (BE La 3d5/2 − BE O 1s) = 304.7 eV as key parameters in comparison with those in several titanium- and lanthanum-bearing oxides.
Investigating Characteristics of Increasing Molecular Weight Cutoff Polyamide Nanofiltration Membranes Using Solutes Rejection and Atomic Force Microscopy

In this article, three nanofiltration (NF) membranes of increasing molecular weight cutoff ranging from 200 to 2000 were characterized by using solute rejection method and atomic force microscope (AFM) imaging. The membranes were all made of polyamide; thus, by using membranes made from the same polymer, it is hoped that the uncertainty imposed by the polymeric materials is eliminated and a better understanding of the relationship between the membrane characteristics and its separation performance is gained. Three approaches were used to fit the solute rejection data: characterization using information provided by the manufacturer, characterization using limiting rejection data, and characterization using the full rejection data. The characterization based on the information by the manufacturer was found to be quite misleading especially for larger pore size membranes. The method based on solute rejection data shows that the characteristics of the membranes were within that expected for NF membranes. It was possible to explain some of the membrane rejection performance based on the characteristics obtained. However, the result from AFM study shows the existence of wide pore size distribution of the membranes. This may be the reason why there have been some inconsistencies and non-uniformity in the membranes performance.
Effect of Inorganic Phosphorus Fertilizer and Inoculants on Yield and Phosphorus Use Efficiency of Wheat

To investigate the response of mineral phosphatic fertilizer and inoculum alone or integrated use of these sources on the growth, yield, nutrient uptake and phosphorus use efficiency of wheat. Treatment combinations were: T 0 =Control, T 1 = Pseudomonas sp, T 2 = Klebsiella sp, T 3 = Pseudomonas sp + 15 kg P ha -1 , T 4 = Klebsiella sp + 15 kg P ha -1 and T 5 = 30 kg P ha -1 . Trials were laid out in a randomized block design with four replications having unit plot size of 5 m × 3 m and wheat was the test crop. Maximum grain and straw yield (2.13 and 2.84 t ha -1 ) were recorded in T 3 (PSB 7 + 15 kg P ha -1 ) and T 4 (PSB 19 + 15 kg P ha -1 ) treatments at Pabna and Rajshahi, respectively. Pseudomonas sp for Pabna and Klebsiella sp for Rajshahi along with triple super phosphate showed better performance than other treatments in respect of wheat yield, nutrient uptake and quality of soil. Phosphate solubilizing bacteria alone also increased phosphorus use efficiency during crop production. A positive significant correlation was observed between yield contributing characters and grain yield of wheat. Based on these reults it may be concluded that, phosphate solubilizing bacteria contributed from unavailable to available form of soil phosphorus and stimulated the available form of applied phosphatic fertilizer as a result increased nutrient uptake and yield of wheat.

Atrazine and nitrate levels found in ground water samples from an unconfined aquifer in the agricultural area of Chamusca (Portugal) are reported. High levels of both, atrazine (0.3–0.4 μg/L) and nitrates (≍100 mg/L) were found in Azinhaga area, located downstream to the main corn production area.
Composition of Organic Matter Fractions for Explaining Wettability of Three Forest Soils

Soil organic matter (SOM) as a solid or as a film at mineral surfaces affects wetting properties in unsaturated soil. Soil organic matter mostly consists of a heterogeneous mixture of components with hydrophilic and hydrophobic functional groups. This paper analyzes relations of SOM to soil wettability by considering functional group compositions of different soluble fractions. Forest soil samples from two loamy sand Cambisol profiles (locations Chorin and Steigerwald) and from a Podzol (Waldstein) were used to obtain water [SOM(W)] and sodium pyrophosphate [SOM(PY)] soluble SOM fractions. The hydrophobic (A) and hydrophilic (B) functional groups of bulk soil SOM and of the soluble fractions were evaluated using transmission Fourier-transform infrared (FT-IR) spectroscopy. Advancing liquid-solid contact angles (CA) were determined by using the capillary rise method. For soil organic carbon (SOC) contents 10 g kg -1 . Although hydrophilic groups in FT-IR spectra of SOM(W), SOM(PY), and bulk soil dominated (i.e., A/B ratios between 0.08 and 0.5), soil wettability was reduced (i.e., CA between 88 and 52°). Soil specific relations between CA and A/B ratios could be obtained after introducing relatively soil type independent factors, G. As exponential functions of the SOC/clay relation, the G-factors imitate the effectiveness of functional groups with respect to wettability. The results suggest that in addition to SOC content, the SOM composition may improve explanations of soil wettability if the spatial orientation of SOM functional groups at the SOM-mineral surface in the presence of sorption sites and polyvalent cations is considered.
Pre-extraction and PSAQ pulping of Siberian larch

Abstract The aim of this study was to find conditions under which it is possible to produce hemicelluloses-rich extract from Siberian larch in addition to pre-extracted pulp with a yield comparable to normal kraft pulp. The study was conducted in order to determine proof of concept of a process utilizing Siberian larch for production of papermaking pulp and biochemically obtained value-added products, i.e. biofuels or lactic acid. By pre-extraction at 160 ºC for 60 minutes approximately 17% of the wood material could be dissolved. At kappa number 30, the pre-extracted kraft pulp gave 5% lower total yield than a conventional kraft pulp. Addition of 4% polysulfide (PS) and 0.1% anthraquinone (AQ) on wood increased the pre-extracted kraft pulp yield nearly to the same level as that of regular kraft pulp. Pre-extraction at 160 ºC for 60 minutes allowed reduction of EA charge by 3% on wood and Hfactor by 300-450. The viscosity of the pre-extracted PSAQ kraft pulps was higher than that of conventional larch kraft pulps and had a somewhat inferior strength and optical properties. The results indicate that under optimized conditions it is possible to produce preextracted PSAQ larch pulp without significant losses in pulp yield and quality, and in addition generate a new feed stock of carbohydrates for further utilization for value-added products.
Nonlinear thermal convection in a layer of nanofluid under G-jitter and internal heating effects

This paper deals with a mathematical model of controlling heat transfer in nanofluids. The time-periodic vertical vibrations of the system are considered to effect an external control of heat transport along with internal heating effects. A weakly non-linear stability analysis is based on the five-mode Lorenz model using which the Nusselt number is obtained as a function of the thermal Rayleigh number, nano-particle concentration based Rayleigh number, Prandtl number, Lewis number, modified diffusivity ratio, amplitude and frequency of modulation. It is shown that modulation can be effectively used to control convection and thereby heat transport. Further, it is found that the effect of internal Rayleigh number is to enhance the heat and nano-particles transport.
Beneficial Effect of Morin on Lipid Peroxidation and Antioxidant Status in Rats with Ethanol Induced Dyslipidemia and Liver Injury

Morin, a naturally occurring bioflavonoid protects the development and progression of alcoholic liver disease (ALD). The current study aims to explore the effect of morin on ethanol-induced dyslipidemia and oxidative stress in plasma, erythrocytes and liver mitochondria of rats. Hepatotoxicity was induced in rats by administering ethanol (6g/kg BW) daily for a period of 60 days. Morin (15, 30, 60 and 120 mg/kg BW) was administered to the ethanol-fed rats after 30 days of the experimental period and the treatment was continued upto 60 th day. Ethanol administered rats showed a significant elevation in plasma alanine transaminases, aspartate aminotransferases, alkaline phosphatase and γ-glutamyl transferase. Ethanol induction in rats showed significant elevated levels of lipids and altered lipid profile levels in the plasma. In addition, the levels of thiobarbituric acid-reactive substances and lipidhydroperoxides were also significantly elevated in the plasma, erythrocyte, and hepatic mitochondria of ethanol-fed rats as compared to control rats. Decreased activities/levels of superoxide dismutase, catalase, glutathione peroxidase and reduced glutathione were observed in ethanol-administered rats. Oral administration of morin (15, 30, 60 and 120 mg/kg BW) to the ethanol-fed rats showed significant protective effects on all the biochemical parameters studied which was evidenced by histopathological studies. Oral administration of morin (60 mg/kg BW) showed its high potentiality in attenuating dyslipidemia and oxidative stress in plasma, erythrocytes and liver mitochondrial in ALD by virtue of its potent hepatoprotective, hypolidemic and antioxidant effects.
