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

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

Long term effect of renal denervation on 24 hour abpm blood pressure variability and blood pressure load parameters

The aim of the study was to evaluate the long-term effect of renal sympathetic denervation (RSD) on 24h ambulatory blood pressure measurement (ABPM) and blood pressure load (BP load) in patients with resistant hypertension. The study included 32 patients with treatment-resistant hypertension and performed successful RSD. The effect of renal denervation was significant both in terms of daytime, nighttime and 24-hour arterial pressure, with the most pronounced effect on nocturnal blood pressure. In addition to mean BP reduction we found out a significant improvement of weighted 24 h SD and BP load during follow-up. A long-term effect of the RSD, reported as a reduction in 24-hour systolic blood pressure above 10 mm Hg at month 12, was found in 22 patients (68.8%). In multivariate regression analysis, two parameters remained predictive for successful renal denervation – higher nighttime systolic blood pressure (OR 0.9, 95% CI 0.8-1.005, p = 0.05) and lower pulse pressure (OR 1.13, 95% CI 1.01-1.26, p = 0.03)

Pemetaan Zona Rip Current Sebagai Upaya Peringatan Dini Untuk Bahaya Pantai (Lokasi Kajian : Pantai Kuta Bali)

Wisata pantai merupakan wisata favorit yang mengandung resiko tinggi. Bahaya pantai salah satunya adalah kecelakaan yang terjadi di wilayah pantai dan beberapa kasus kecelakaan yang terjadi di pantai biasanya akibat pengawasan yang lemah, kurangnya pemahaman wisatawan akan bahaya pantai, fasilitas pengawasan yang kurang memadai, atau wisatawan yang tidak dapat berenang kemudian terseret arus sampai ke tengah laut. Menurut Daryono (2010), arus yang membawa korban tersebut adalah Rip Current. Penelitian ini bertujuan untuk Tujuan penelitian ini adalah untuk mengetahui zona potensi rip current, Mengetahui persentase potensi terjadinya rip current di Pantai Kuta Bali. Metode penelitian yang digunakan adalah metode kuantitatif. Hasil penelitian menunjukkan bahwa Pantai Kuta Bali dibagi kedalam 2 (dua) zona, yaitu zona aman dan zona bahaya. Pada zona aman terdapat 2 (dua) pola rip current, karena gelombang yang datang tidak membentuk sudut yang tegak lurus terhadap garis pantai, sedangkan pada zona berbahaya terdapat 7 (tujuh) pola rip current. Persentase terjadinya rip current di sepanjang Pantai Kuta Bali adalah sebesar 83%, nilai ini berdasarkan kejadian gelombang pecah tipe plunging. Slope pantai akan mempengaruhi terjadinya rip current. Pada penelitian ini pantai landai memiliki potensi rip current paling besar yaitu sebesar 91.5% yang memiliki slope sebesar 7.5˚, berada pada koordinat 08˚43'23” LS dan 115˚10'9” BT. Sedangkan, pantai datar memiliki potensi rip current yang kecil yaitu sebesar 51.5% dan memiliki slope antara 0.5˚ sampai 1.8˚
