A domestic model for successful implementation of enterprise resource planning (ERP) systems in Iranian manufacturing enterprises

This research investigates the human-behavioral dimension of technology acceptance in enterprises. It is evident that accepting a technology depends on the underlying circumstances of the environment. We have approached this issue from two different angles of social and technological architecture. The research tries to explore proper enterprise architecture for ERP system acceptance. Social Architecture (SA) is defined as the set of circumstances that makes people behave in a particular way. So behavior of persons (employees of an enterprise) can be a function of SA. Hence acceptance of a system can be dictated by SA and manipulating SA can result in desirable success for a technology system. We have achieved various variables of social architecture and have examined their relevance to system acceptance and success in related enterprises (research domain) beside technological architecture variables. The results have indicated that a special form of social and technological architecture can lead to success for ERP system in the enterprises of the research domain. This gave us a model of architecture

Multilayer Thin Films on Fine Particles

The tunable construction of multilayer thin-film-based particulate has opened up new horizons in materials science and led to exciting new developments in many scientific areas during the past two decades. Indeed, to utilize the synergistic properties of thin film coatings and the core particles, the thin film immobilized on fine particles can be a promising approach. The interaction between the thin films and the core fine particles results in adjustable properties of the coated particles. Therefore, such coated systems have been considered as an important class of emerging powder technology for a wide range of applications. Namely, multilayer structural features can lead to designing a highly active and selective catalytic systems. In addition, multilayer-coated nano/micro particles (NMPs) can be employed in the development of many new properties, ease of functionalization, conjugation of biomolecules, etc. Such structure with multilayer coatings can also revolutionize the energy storage and conversion systems

Effects of Irrigation Period on Biochemical Changes of some Citrus Species

Water is the most important factor for plant growth, and deficiency of water is a reason for drought stress. In drought stress situations, antioxidant system and some biochemical properties are changed. To identify the effect of drought stress on some types of citrus species, we examined different irrigation periods on citrus cultivars. In this study, plants were irrigated every four, eight, twelve, and sixteen days. Antioxidant, superoxide dismutase (SOD), peroxidase (POD), chlorophyll content, relative water content (RWC), and proline were measured. Results showed that with increased irrigation period antioxidant capacity, SOD, POD, and proline were increased in all three citrus cultivars, but chlorophyll content and RWC were decreased. All cultivars expressed similar changing pattern and it means that with decrease of water availability antioxidant system activity increases to protect plants against drought stress

Influence of Moderate and Severe Exercise on Memory Formation and Anxiety-like Behaviors in Male Wistar Rat

Introduction: Recent researchers have showed that regular exercise induces positive effects on cognitive functions. Exercise intensity and timing of cognitive assessment may have an interactive effect on cognitive changes. Previous researches suggest that moderate intensity treadmill running has the most consistent benefit to cognitive function. In contrast, studies find positive, negative, or null effects to cognitive function after high intensity treadmill running. The primary objective of the present study was to compare the cognitive effects of intensity treadmill running protocol 1 (Low intensity), protocol 2 (Moderate intensity) and protocol 1 plus 2 (High intensity).Materials and Methods: Male Wistar rats were divided into four groups (n=7 in each group) including: sedentary (Non-exercise), protocol 1, protocol 2, and combination of protocol 1 and 2. Step-through passive avoidance and elevated-plus maze apparatus have been used to test parameters of passive avoidance learning and anxiety-like behaviors.Results: These findings showed that combination of both protocols (Protocol 1 with protocol 2) decreased step-through latency in the passive avoidance apparatus indicating memory impairment [P<0.05]. Moreover, the data revealed that different protocols for exercises did not alter %OAT [P<0.001], %OAE %OAT [P>0.05] and locomotor activity %OAT [P<0.05] compared to control group but not others.Conclusion: High intensity exercise not only induced beneficial effect but also impaired memory formation. 

The Art of Laughing: A Study of the Tempo-Spatial Matrix in Oliver Goldsmith’s She Stoops to Conquer

Oliver Goldsmith’s She Stoops to Conquer (1773) was staged only two weeks after the publication of his Essay on the Theatre, in which he famously compared sentimental comedies with what he described as laughing comedies. The play thus illustrates Goldsmith’s principles for his ideal laughing comedy. One of the aspects of this type of comedy, which has rarely been addressed, is its representation of the matrix of temporal and spatial elements, or what Mikhail Bakhtin calls a chronotope. The present study is thus aimed at investigating She Stoops to Conquer in terms of Bakhtinian chronotope. The study argues how different chronotopes have influenced the behaviours as well as the decisions of characters in the play. Moreover, it shows that the chronotopic framework can shed new light on the play’s portrayal of the class divisions in the eighteenth century, when the middle class was emerging in England’s social system

Effect of oral vitamin C on atrial fibrillation development after isolated coronary artery bypass grafting surgery: A prospective randomized clinical trial

Background: Some evidences have shown the role of antioxidant vitamins in preventing atrial fibrillation (AF) after coronary artery bypass grafting (CABG) surgery. We sought to determine the effect of oral vitamin C on the incidence of postoperative AF in patients undergoing elective isolated on-pump CABG surgery. Methods: One-hundred patients who underwent isolated CABG surgery were prospectively assigned into two groups: Group 1 — 50 patients received 2 g of oral vitamin C before and 500 mg twice daily lasting for 5 days after surgery; Group 2 — 50 patients as the control group did not receive any. All patients were continuously monitored after surgery in the intensive careunit (ICU), and then Holter monitoring was implemented for 72 h. Results: The mean of patients’ age was 61.31 ± 6.42 years. Postoperative AF occurred in 16 and 4 patients in control and treatment groups, respectively (32% vs. 8%, p = 0.003). The ICU stay was 1.79 ± 0.313 and 2.10 ± 0.61 days for vitamin C and control groups, respectively (p = 0.002). The hospital stay was significantly lower in vitamin C group compared with that of the control group (5.32 ± 0.59 vs. 5.74 ± 1.30 days, respectively, p = 0.041). Baseline erythrocyte sedimentation rate (OR 1.030, 95% CI 1.003–1.058, p = 0.030) and taking vitamin C (OR 8.068, 95% CI 1.783–36.517, p = 0.007) were the independent predictors of postoperative AF. Conclusions: Oral vitamin C can be safely used to decrease the incidence of postoperative AF in patients undergoing elective isolated on-pump CABG surgery.

Toward a More Accurate Web Service Selection Using Modified Interval DEA Models with Undesirable Outputs

With the growing number of Web services on the internet, there is a challenge to select the best Web service which can offer more quality-of-service (QoS) values at the lowest price. Another challenge is the uncertainty of QoS values over time due to the unpredictable nature of the internet. In this paper, we modify the interval data envelopment analysis (DEA) models [Wang, Greatbanks and Yang (2005)] for QoS-aware Web service selection considering the uncertainty of QoS attributes in the presence of desirable and undesirable factors. We conduct a set of experiments using a synthesized dataset to show the capabilities of the proposed models. The experimental results show that the correlation between the proposed models and the interval DEA models is significant. Also, the proposed models provide almost robust results and represent more stable behavior than the interval DEA models against QoS variations. Finally, we demonstrate the usefulness of the proposed models for QoS-aware Web service composition. Experimental results indicate that the proposed models significantly improve the fitness of the resultant compositions when they filter out unsatisfactory candidate services for each abstract service in the preprocessing phase. These models help users to select the best possible cloud service considering the dynamic internet environment and they help service providers to improve their Web services in the marke
