Non-traditional Ocean Deep Convection

Convection in a homogeneous ocean is investigated by numeri cally ntegrating the three dimensional Boussinesq equations in a tilted-rotating frame (f-F-plane) subject to a ne gative buoyancy flux (cooling) at the surface. The study focu ses on determining the influence of the angle (tilt) between the a xis of rotation and gravity on the convection process. To thi s end we vary two essential parameters : (i) the magnitude of th e surface heat flux, and (ii) the angle (tilt) between the axis of rotation and gravity. The range of the parameters investi gated is a subset of typical open ocean deep convection event s. We demonstrate that when gravity and rotation vector are til t d with respect to each other : (i) the Taylor-ProudmanPoincaŕe theorem leaves an imprint in the convective structures, (i i) a horizontal mean circulation is established, (iii) the second order moments involving horizontal velocity compon ents are considerably increased. Mots clefs : Geophysical fluid dynamics, convection, traditional approximation
Narcissism in Iranian auditing profession

A B S T R A C T This study investigates the level of Narcissism among 185 Iranian auditors groups and narcissism has been used to describe people behavior in people groups. The present study uses a questionnaire to measure Narcissism and to examine the hypotheses of the paper analysis of variance and T-test are used. The results of testing hypotheses show that the level of narcissism was significantly different in auditors groups in private sector. However, in public sector, the difference between narcissistic personality in auditors' groups is not significant. Results of the study also indicated that, in private sector, narcissistic personality in young generation of auditors was higher than audit old generation. These results confirm previous studies on narcissism indicating that narcissistic behavior was high among young generation. We suggest the Iranian association of certified public accountants (IACPA) to review the ethical training needs for auditors. In addition, audit firms can provide a system to increase interaction among old generations of auditors with young generation of auditors.

CLINICAL EVALUATION OF TRIPLE AND QUADRUPLE HELICOBACTER PYLORI ERADICATION THERAPY IN PEPTIC ULCER PATIENTS WITH DIFFERENT ABO BLOOD GROUP PHENOTYPES

Objective: This study aimed to examine the pathological changes in gastric mucosa of Helicobacter pylori-infected peptic ulcer patients carrying different ABO phenotypes and to study the response to the 14 days’ standard triple therapy and 10 days’ quadruple therapy in peptic ulcer patients according to their ABO phenotypes.Methods: Interventional prospective randomized-controlled open-label study was performed on newly diagnosed patients with PUD. The H. pylori-positive patients were allocated into two major study groups in which they are subdivided according to ABO blood group phenotypes: Group 1 received standard H. pylori eradication triple therapy and Group 2 received standard H. pylori eradication quadruple regimen. Patients were monitored after 2 months for successful H. pylori eradication.Results: Chronic active gastritis was significantly high in patients carrying blood Group O phenotype (81.25%), while the atrophic gastritis and intestinal metaplasia were significantly high in patients carrying blood Group A phenotype (25.00% and 16.67%), respectively. 14 days’ triple therapy showed significantly lower eradication rate in H. pylori-infected peptic ulcer patients carrying blood Group O phenotype (p<0.01), meanwhile higher response was found among patients with blood Group B. 10 days’ quadruple therapy produced a significant high eradication rate in H. pylori-infected patients carrying blood Group O than those with blood Group A (p<0.01), but still both showed lower response compared to that in patients carrying blood Group B and AB phenotypes. Elderly patients showed significantly less healing efficacy than younger patients (p<0.01), and the least healing rate was noticed in female patients after both regimens.Conclusion: Lower eradication rate in H. pylori-infected was noticed in peptic ulcer patients carrying blood Group O mainly than those with other blood groups and particularly those with duodenal Ulceri. 10 days’ quadruple therapy showed significant higher eradication rate in H. pylori infection and a better ulcer healing efficacy.
An approach for shaped-beam pattern synthesis with spherical antenna array

A modern high-speed aircraft will be installed with multiple antennas protruded from its structure for communication purpose, navigation, Instrumental Landing System etc. There may be more than 25 antennas that can cause considerable amount of drag that will ultimately affect the efficiency of aircraft. Nowadays, integration of these antenna on the surface of the aircraft is very much required and important. Need of these antenna will be more pronounced when large-aperture antennas are required in applications like military airborne radars,satellite communication etc. In this work, spherical shaped antenna array has been proposed and discussed in details with consideration of mutual coupling. Further, proposed spherical array has been utilized to generate Shaped-patterns. Radiation patterns like Cosecant-squared shaped pattern which are significantly applied in radar and navigation applications is generated using DE & SSO optimization techniques and compared with conventional arrays. Further, the work is extended to a newly designed shape of Indian geographical boundary-line with the proposed spherical array. Besides simulation results, to have a practical understanding of its radiation pattern, spherical array is modelled with patch dipole in Computer Simulation Technology(CST) software and is processed to obtain all the important parameters like Polar & 3D far field Radiation pattern, Side Lobe Level, Beam-width, S-parameters, E-field & H-field patterns, current-density etc
VARIATION OF SESAMIN AND SESAMOLIN CONTENTS IN SESAME CULTIVARS FROM CHINA

A collection of 62 sesame cultivars from China were analyzed for sesamin and sesamolin contents in seeds using HPLC. Results showed the sesamin and sesamolin contents of these cultivars ranged from 0.82 to11.05 mg/g and 1.35 to 6.96 mg/g, respectively. About 60.0% of the cultivars stayed in the range from 6.0 to 9.0 mg/g in the total content of sesamin and sesamolin. On average, cultivars with white seed coat color had higher sesamin content than those samples with black color. The correlation coefficient between sesamin and sesamolin of the cultivars with different seed colors ranked as white (R = 0.44) < medium (R = 0.75) < black (R = 0.96). The landraces had higher sesamin and sesamolin contents than other cultivars significantly. The results of this study exhibited useful lignan information of the cultivars from China and identified potential cultivars having high sesamin or sesamolin for functional food, pharmaceutics and cosmetic industries.

Large-scale environment of z ~ 5.7 C IV absorption systems - I. Projected distribution of galaxies

Metal absorption systems are products of star formation. They are believed to be associated with massive star forming galaxies, which have significantly enriched their surroundings. To test this idea with high column density CIV absorption systems at z~5.7, we study the projected distribution of galaxies and characterise the environment of CIV systems in two independent quasar lines-of-sight: J103027.01+052455.0 and J113717.73+354956.9. Using wide field photometry (~80x60h$^{-1}$ comoving Mpc), we select bright (Muv(1350\AA)<-21.0 mag. ) Lyman break galaxies (LBGs) at z~5.7 in a redshift slice \Delta z~0.2 and we compare their projected distribution with z~5.7 narrow-band selected Lyman alpha emitters (LAEs, \Delta z~0.08). We find that the CIV systems are located more than 10h$^{-1}$ projected comoving Mpc from the main concentrations of LBGs and no candidate is closer than ~5h$^{-1}$ projected comoving Mpc. In contrast, an excess of LAEs -lower mass galaxies- is found on scales of ~10h$^{-1}$ comoving Mpc, suggesting that LAEs are the primary candidates for the source of the CIV systems. Furthermore, the closest object to the system in the field J1030+0524 is a faint LAE at a projected distance of 212h$^{-1}$ physical kpc. However, this work cannot rule out undiscovered lower mass galaxies as the origin of these absorption systems. We conclude that, in contrast with lower redshift examples (z<3.5), strong CIV absorption systems at z~5.7 trace low-to-intermediate density environments dominated by low-mass galaxies. Moreover, the excess of LAEs associated with high levels of ionizing flux agrees with the idea that faint galaxies dominate the ionizing photon budget at this redshift.
Plant Disease Detection Using Different Algorithms

This will help to design different disease control strategy which will be beneficial in agriculture field. Automatic detection and analysis of disease are established on their particular symptoms and the cost intensity is very helpful for farmers. It is a major challenge for the early detection of diseases in agriculture science. An organism like fungi, bacteria, virus etc is the major causes of plant diseases so the enhancement of proper approach in certain areas is very necessary. All these studies are focused on the early detection and classification of the plant lesion diseases.
What is required for the viability of metal recovery from municipal solid-waste incineration fly ash? - Design and assessment of a process plant for copper extraction

The incineration of municipal solid waste produces large amounts of fly ashes, today in Sweden around 200 000 tons/yr. The ashes normally contain a considerable amount of valuable and hazardous metals. To fulfil the environmental regulations, most of these fly ashes can be deposited only in specific sites. This handling costs, requires energy and leads to emissions in the transportation to the deposit site. This work, taking departure in laboratory experiments for crucial steps, discusses possible chemical processing schemes and from this develops an overall design of a plant for the extraction and production of copper from the fly ash generated in a fluidized bed waste incineration plant. It also addresses the economic viability and environmental impact of the suggested processing in comparison to current handling, which involves transport to and disposal of the fly ash in Norway. The proposed process involves a leaching step, a solvent extraction process, a stripping step where the copper is transferred to an aqueous phase and finally electrolysis. By quantitative modelling and cost estimates of the processing steps of the proposed plant we identify the most important factors for the economics and environmental impact of the plant. In addition, we quantify the necessary recycling rates of the different process chemicals for achieving profitability. We conclude that a crucial factor is the recycling rate of the used organic solvent. Important parameters are also the handling costs and transportation needs of the rest products. For instance, a major benefit of the process is if treated fly ash can be reclassified such that it is allowed to be disposed into the own close-up hazardous waste landfill thus lowering the costs and environmental impacts. An extension of the process to include also the extraction of metals other than copper, for instance zinc, should be an interesting further development to consider.
On the hiatus in the acceleration of tropical upwelling since the beginning of the 21st century

Abstract. Chemistry–climate models predict an acceleration of the upwelling branch of the Brewer–Dobson circulation as a consequence of increasing global surface temperatures, resulting from elevated levels of atmospheric greenhouse gases. The observed decrease of ozone in the tropical lower stratosphere during the last decades of the 20th century is consistent with the anticipated acceleration of upwelling. However, more recent satellite observations of ozone reveal that this decrease has unexpectedly stopped in the first decade of the 21st century, challenging the implicit assumption of a continuous acceleration of tropical upwelling. In this study we use three decades of chemistry-transport-model simulations (1980–2013) to investigate this phenomenon and resolve this apparent contradiction. Aside from a high-bias between 1985–1990, our model is able to reproduce the observed tropical lower stratosphere ozone record. A regression analysis identifies a significant decrease in the early period followed by a statistically robust trend-change after 2002, in qualitative agreement with the observations. We demonstrate that this trend-change is correlated with structural changes in the vertical transport, represented in the model by diabatic heating rates taken from the reanalysis product Era-Interim. These changes lead to a hiatus in the acceleration of tropical upwelling between 70–30 hPa and a southward shift of the tropical pipe at 30 and 100 hPa during the past decade, which appear to be the primary causes for the observed trend-change in ozone.
Interactive comment on “ Degradation Kinetics and Secondary Organic Aerosol Formation from Eugenol by Hydroxyl Radicals ” by Changgeng Liu

reaction with OH, were SO2/NO2 added? And for SOA yield studies, what was the reference compound to derive OH? It seemed that here SO2/m-xylene/1,3,5-TMB are all not appropriate to sever as the reference compound since m-xylene/1,3,5-TMB they themselves are also SOA precursors and SO2 instead influence the SOA yield. It is quite confusing. The authors need to clarify in Table 1 what combinations (including reference compound for deriving OH) of species are prepared for obtaining the rate constant, and what combinations instead are for studying the SOA yield.
Residue Dynamics and Safe Pre-Harvest Interval of Chlorpyrifos in Water Dropwort

Chlorpyrifos residue contents in market water dropwort, residue dynamics of chlorpyrifos and the safe pre-harvest interval (SPHI) in field water dropwort were conducted in Changzhou, Jiangsu Province, China. The results showed that concentrations of chlorpyrifos residues in more than half of the market samples (57%) exceeded the maximum allowable concentration (MAC, 0.05 mg kg-1), according to the Chinese Standard (GB 2763 – 2014). The average chlorpyrifos content in the samples was 0.23 mg kg-1 that was 3.6 times higher than the MAC. Study on the residue dynamics of chlorpyrifos demonstrated that the half-life of chlorpyrifos residues in the water dropwort of early-sowing (in summer) and late-sowing (in autumn) were 4.1 and 5.4 days, respectively, and it took 31.2 and 43.1 days, respectively, for chlorpyrifos residues to decrease to the MAC level. In normal application dosage (recommended for vegetables), the SPHI was 30-35 days for the water dropwort of early-sowing, and 40 days for the water dropwort of late-sowing, which were much longer than the recommended pre-harvest interval (seven days) according to the Chinese Standard ((GB/T 8321 – 2000)). It may be the cause of high chlorpyrifos residue concentrations in market water dropwort.
The development potential of clusters in Romania

Nations and regions find themselves in a constant competition for attracting direct foreign investments, the most important producers, specialized work force, the best researchers etc. From this point of view the former communist countries could be in an unfavorably situation because they just recently managed to adopt the system of the market economy. Clusters are seen as a solution for the economical success in the global competition. The western European countries have in this way a one century tradition, and continue to sustain and finance programs for the development and expansion of clusters. Taking in account the western experience, the question arises if also in the former communist countries clusters can give the key for development and rapid fulfillment of objectives regarding cohesion, regional development, competitiveness at international and global level. The paper investigates the potential of forming clusters in Romania and gives an orientation in the decisional process for founding, localization, development of clusters.
Evaluation of drought impact on groundwater recharge rate using SWAT and Hydrus models on an agricultural island in western Japan

Abstract. Clarifying the variations of groundwater recharge response to a changing non-stationary hydrological process is important for efficiently managing groundwater resources, particularly in regions with limited precipitation that face the risk of water shortage. However, the rate of aquifer recharge is difficult to evaluate in terms of large annual-variations and frequency of flood events. In our research, we attempt to simulate related groundwater recharge processes under variable climate conditions using the SWAT Model, and validate the groundwater recharge using the Hydrus Model. The results show that annual average groundwater recharge comprised approximately 33% of total precipitation, however, larger variation was found for groundwater recharge and surface runoff compared to evapotranspiration, which fluctuated with annual precipitation variations. The annual variation of groundwater resources is shown to be related to precipitation. In spatial variations, the upstream is the main surface water discharge area; the middle and downstream areas are the main groundwater recharge areas. Validation by the Hydrus Model shows that the estimated and simulated groundwater levels are consistent in our research area. The groundwater level shows a quick response to the groundwater recharge rate. The rainfall intensity had a great impact on the changes of the groundwater level. Consequently, it was estimated that large spatial and temporal variation of the groundwater recharge rate would be affected by precipitation uncertainty in future.
ESTIMATION OF ALKALOIDS AND PHENOLICS OF FIVE EDIBLE CUCURBITACEOUS PLANTS AND THEIR ANTIBACTERIAL ACTIVITY

Objective: Objective of the present work was qualitative and quantitative estimation of alkaloids and phenolics of five edible cucurbitaceous plants and to evaluate their antibacterial activity against some human pathogenic bacteria. Methods: Total alkaloid present was determined by acid-based titrimetric methods using methyl red as an indicator and observing a faint yellow end point. Total phenolics were estimated by follin-ciocaltue’s method using tannic acid as standard. Antibacterial activity was determined by Disc diffusion method using SRL Agar medium. The 70% ethanolic dried powdered was dissolved in 20% DMSO at different concentration to carry out the anti-microbial activity. Results: It was found that all the experimental plants contained almost equal amount of alkaloids but their phenolic contents as tannic acid equivalents were different. Alkaloids content of five Cucurbitaceous plants were found to vary from 1.15 g % to 1.34 g % and phenol content was varied from 4.54 mg/g to 10.13 mg/g. All the selected Cucurbitaceous plants were active against the tested pathogens, except against V. cholerae non.0139 (L4). Only the 70% ethanolic leaf extract of Momordica charantia (Linn.) showed a relative percentage inhibition from 15.02 to 16.63. So, Momordica charantia (Linn.) extract was the most active among five selected plants against the tested pathogens. Conclusion: The activity might be due to the presence of alkaloids and phenols. However, the extent of activity or zone of inhibition was found varied for different extracts might be due to the difference in the constituents present in the plant extracts.
Experimental Evaluation of ZigBee-Based Wireless Networks in Indoor Environments

ZigBee is an emerging standard specifically designed for wireless personal area networks (WPANs) with a focus on enabling the wireless sensor networks (WSNs). It attempts to provide a low-data rate, low-power, and low-cost wireless networking on the device-level communication. In this paper, we have established a realistic indoor environment for the performance evaluation of a 51-node ZigBee wireless network. Several sets of practical experiments have been conducted to study its various features, including the (1) node connectivity, (2) packet loss rate, and (3) transmission throughput. The results show that our developed ZigBee platforms could work well under multihop transmission over an extended period of time.
