The impact of the prevailing organizational culture on the adoption of green marketing in chemical-industry companies in three Arab states in west Asia

The objective of this study was to investigate the impact of the prevailing organizational culture on the adoption of green marketing in chemical-industry companies in three countries: Syria, Kuwait and Jordan. The research used a survey methodology. A questionnaire was designed and administered simultaneously in the three countries using three different samples consisting of 220 respondents, 12 respondents, and 132 respondents, respectively. The questionnaires collected from the three samples were coded and analyzed. The study concluded that the organizational culture in the samples from the three countries has positive attitudes towards the adoption of green marketing. The Kuwaiti sample has the highest level of positive attitudes in comparison with the other two samples. The task-oriented culture is the dominant prevailing organizational culture in the chemical-industry companies located in Syria and Jordan, but a fulfillment-oriented culture is the dominant prevailing organizational culture in chemical-industry companies located in Kuwait. Our analysis shows that the impact of the prevailing organizational culture differs in accordance with differences in employee education level, country, and years of experience.Organizational culture; Chemical industrial companies; Green marketing; Culture

Analisis Produktivitas, Pendapatan dan Kesejahteraan Petani Karet Eks Upp Tcsdp di Desa Semelinang Darat Kecamatan Peranap Kabupaten Indragiri Hulu

This study aims to analyze the productivity, the revenue, the households income structure, the pattern of households expenditure, and the welfare of households of the smallholder rubber plantation of ex-TCSDP development. Research was done by survey at Semelinang Darat Village. Data were collected from 30 small-holders rubber farmers using purposive sampling technique. Analysis of the results showed that the productivity of smallholder rubber plantation as 2.79 ton/ha/year, the revenues of smallholder rubber plantation as Rp 6.466.065/ha/year. The structure of household income derived from agriculture is 85,07 percent and 14,93 percent for non-agricultural income. The pattern of household expenditure shown that the food expenditure as 32,36 percent and non-food expenditures as 67,64 percent. Result also show that the household of the smallholder rubber plantation at Semelinang Darat Village have the total expenditure more than 240 kg of rice equivalent. The household of small-holders rubber plantation have the total expenditure above the poverty line (Rp 369.210 /capita/month). The household welfare using the 14 indicators of relative poverty by Indonesian Statistic show that 83,33 percent household have ability to fullfill the basic need or prosperous, while 16,67 percent is almost prosperous

A Hydrodynamic Study of Benzyl Alcohol Oxidation in a Micro-Packed Bed Reactor

This paper was presented at the 4th Micro and Nano Flows Conference (MNF2014), which was held at University College, London, UK. The conference was organised by Brunel University and supported by the Italian Union of Thermofluiddynamics, IPEM, the Process Intensification Network, the Institution of Mechanical Engineers, the Heat Transfer Society, HEXAG - the Heat Exchange Action Group, and the Energy Institute, ASME Press, LCN London Centre for Nanotechnology, UCL University College London, UCL Engineering, the International NanoScience Community, www.nanopaprika.eu.The various flow regimes prevalent during gold-palladium catalyzed benzyl alcohol oxidation in a micro-packed bed reactor and their influence on reaction performance are identified. The reaction is studied in a 300μm deep x 600μm wide silicon-glass micro-structured reactor packed with 65μm catalyst particles at a temperature of 120°C, pressure of 1 bar (g), using pure oxygen and neat benzyl alcohol as the feed. Significant improvement in the conversion and selectivity to the main product, benzaldehyde, is observed with increasing gas flowrate and decreasing liquid flowrate, which coincides with a change in the flow pattern from “liquid-dominated slug” (segregated regions of liquid and gas slugs) to “gas-continuous trickle” (thin film coated catalyst particles with gas flowing through the voids). The latter flow regime results in enhanced external mass transfer due to an increase in the available interfacial area and shorter diffusional distances. Results show selectivity up to 81% at a catalyst space time of 76 gcatgalc(-1).s, outperforming a conventional batch laboratory reactor

Model Support Vector Machine Berbasis Particle Swarm Optimization Untuk Prediksi Penyakit Liver

Hati adalah organ yang paling besar dan penting bagi tubuh kita. Kita tidak bisa hidup tanpa hati. Penyakit hati merupakan peradangan yang disebabkan oleh infeksi virus, bakteri atau bahan-bahan beracun sehingga hati tidak dapat melakukan fungsinya dengan baik serta tidak mudah ditemukan dalam tahap awal dalam mendiagnosis penyakit hati. Penanganan pasien dengan penyakit hati pada tahap awal akan memperpanjang hidup pasien. Banyak penelitian menggunakan model Support Vector Machine untuk memprediksi penyakit hati tetapi nilai akurasi yang dihasilkan kurang akurat. Dalam penelitian yang dilakukan ini model algoritma support vector machine dan model algoritma support vector machine berbasiskan particle swarm optimization untuk mendapatkan aturan untuk memprediksi penyakit liver dan memberikan nilai yang lebih akurat dari akurasi. Setelah pengujian dengan dua model support vector machine dan support vector machine berbasiskan particle swarm optimization, mendapatkan hasil dari model algoritma support vector machine nilai akurasinya 71,36% dan nilai akurasi dari AUC sebesar 0.500, sedangkan pengujian menggunakan algoritma suppport vector machine berbasiskan particle swarm optimization mendapatkan hasil nilai akurasinya sebesar 77,36% dan nilai AUC 0.661 untuk tingkat diagnosa klasifikasi yang baik. Kedua metode ini memiliki berbagai tingkat akurasi sebanyak 6,00% dan selisih nilai AUC 0.16

Defect Signal Analysis For Nondestructive Testing Assesment

For fast assessment of defects in conductive materials, Eddy current testing is a most widely non-destructive testing (NDT) evaluation methods utilized in industry, especially in oil and gas, aircraft, nuclear and coating industries. Experimental studies of eddy current testing have emerged as an important approach alongside numerical modelling. This paper focus on investigating the defect signal characteristics of carbon steel pipe weld coating inspection using different frequency eddy current testing. The optimum frequency of carbon steel pipe weld coating is verified. Tests have been conducted utilizing positive and negative scanning method with frequency between 10 kHz to 100 kHz. Artificial defect use of this test is the horizontal affected zone (HAZ), centre line and transverse crack. Experimental results showed the frequency can be impression to the amplitude and phase angle eddy current testing signal. The optimum frequency for carbon steel weld plate is 100 kHz
