Entrepreneurship in the Context of Organizational Culture
The importance of entrepreneurship and citizenship behavior is obvious. To achieve development, organizations should pave the way for development of these two items in their human resources. These two factors in development of economic and social issues are the cheapest tools with the highest efficiency. In order to discuss the importance of organizational culture for the growth of these two concepts, culture plays the role of mother womb for fetus growth (entrepreneurship and citizenship behavior). The present study aimed to evaluate the relationship between organizational culture with entrepreneurship and organizational citizenship behavior in Telecommunication Company of Golestan province. The study is applied in terms of purpose and descriptive-correlation in terms of method. The study population is 400; its 200 people sample is extracted by simple random sampling method. In statistical analysis, Cronbach’s alpha, Kolmogrov-Smirnov, Spearman correlation coefficient and Wilcoxon test are used. The results show that there is a direct and significant association between organizational culture and entrepreneurship and organizational citizenship behavior
The Study of New Method of Modern Well Testing By Using Surface Control
The accurate infonnation of the in-situ reservoir condition is very significant to every phase
in petroleum engineering thus help the reservoir engineers to have better understanding on
the reservoir and completion efficiency qualitatively and quantitatively. The analysis toward
pressure data recorded during well test has been used for many years to evaluate the reservoir
characteristic especially in determining the value of well damage (skin), effective
permeability and heterogtllleity behavior. However, well testing has become increasingly
unpopular especially in exploration and appraisal wells due to the expensive costs, safety and
environmental impact factors. For the production well, the potential revenue loss during
buildup testing is one of the reason to decline well testing in their activity. For past 30 years,
many methods have been published to improved the well testing technique but the problem of
the cost either the expensive tools or the production loss is still occur. This paper presented
the new technique of implementing well testing by using surface control which reduces the
cost and eliminates the risk of running tools into well bores. This new technique also created
to overcome the problem of the constant rate which in practical it is not achieved by allowing
the varying rate test. Thus, it will increase better interpretation with lower the uncertainty
ranges. The idea of this new technique will overcome all the weakness of conventional well
testing and brings the significant impact to the industry. First, the general framework of the
flowing surface-bottomhole pressure calculation will be presented which will be compared
with the measured data from field and also with the calculation from the computer program
using Modified Hagedorn and Brown Correlation. The pressure difference between the
calculated flowing bottomhole pressure with measured depth averagely 3 to 6 psia. Next, the
study of Tiab's Direct Synthesis method with the available multi rate test data taken from
published source is analyzed and compared the result with the conventional analysis. The
results obtained from the Tiab's Direct Synthesis method are very close with real data which
the percentage difference of the absolute permeability estimate is about 0.36%. The specific
procedure required in order to implement this new technique which focusing on choke
control and test design will also be explained. The report also presents some case study of
application of well testing toward estimating reservoir parameters for Malaysia fields
Comparison of Efficacy and Side Effects of Azithromycin and Co-Amoxiclav in the Treatment of Acute Sinusitis in Adults: A Randomized Clinical Trial
Background: Regarding high prevalence of common cold and sinusitis in Chaharmahal and Bakhtiari Province
and the lack of studies on patients referring hospitals in this province, this study was conducted to determine and
compare the efficacy and side effects of azithromycin and co-amoxiclav.
Methods: This study was a double-blinded randomized clinical trial. The study population of this clinical trial
was consisted of 90 patients with acute sinusitis aged 12-65 years. At least two major criteria or one major
criterion and two minor criteria with duration of at least 7 days and at most 28 days, were some of the sinusitis
diagnostic criteria for inclusion of the patients into the study. The patients were examined for symptoms prior to
and twice after the treatment. The treatment was administration with 500 mg azithromycin tablet per day for
three days in group 1 (G1) and 625 mg co-amoxiclav tablet every 8 h for 10 days in group 2 (G2). The data were
analyzed by repeated measures analysis of variance, independent t-test, and chi-square in Stata software and P <
0.05 was considered significant.
Results: Mean±Standard deviation age of all patients was 32.14±9.91 years. Out of 90 participants in the study,
50 (55.56%) were male and the rest were female. The patients’ symptoms were quantitatively similar in the two
groups (22.3±2 and 22.2±1.9 in G1 and G2, respectively) prior to the intervention. The score at second
examination decreased to 3.7±2.1 in G1 and to 9.4±2.7 in G2, significantly different from that prior to
intervention and between the two groups (P<0.001). Although the score decreased in the two groups at third
examination, it was not significant in the two groups (P=0.652). The cure rate in azithromycin group was derived
87.5% and 88%, and in co-amoxiclav group 32.4% and 83.3% at the days 5 and 10 of treatment, respectively.
The most prevalent side effects in the two groups were diarrhea and nausea. The prevalence of diarrhea was
obtained 21% and 33% in G1 and G2, respectively.
Conclusion: No significant difference in side effects was seen between the two groups. Although the cure was
faster in the patients treated with azithromycin than those treated with co-amoxiclav, co-amoxiclav is still
considered as adequately working against acute sinusitis bacterial pathogens. In view of this efficacy,
co-amoxiclav seems to lead to no drug resistance and could be used to treat the patients
Logarithmic entropy--corrected holographic dark energy with non--minimal kinetic coupling
In this paper, we have considered a cosmological model with the non--minimal
kinetic coupling terms and investigated its cosmological implications with
respect to the logarithmic entropy-- corrected holographic dark energy
(LECHDE). The correspondence between LECHDE in flat FRW cosmology and the
phantom dark energy model with the aim to interpret the current universe
acceleration is also examined.Comment: 11 pages, 2 figures; Can. J. Phys. Vol. 90, 201
Honey versus diphenhydramine for post-tonsillectomy pain relief in pediatric cases: a randomized clinical trial.
INTRODUCTION
Tonsillectomy is one of the most common surgeries done worldwide and often the first one a child sustains. Pain relief after tonsillectomy is helpful for oral feeding after surgery. Acetaminophen and diphenhydramine have been conventionally used for reducing pain. This study was conducted to compare the effect of honey and diphehydramine on pain relief after tonsillectomy.
MATERIALS AND METHODS
For this randomized clinical trial study, 120 patients of 5 to 12 years undergoing tonsillectomy were recruited. The patients were divided into four groups randomly. After tonsillectomy and beginning of eating, Group A took 5cc honey alone every hour, Group B was given 5 cc 50% honey (mixed with water) every hour, group C was treated with 1mg/kg diphenhydramine every 6 hours and group D was observed without any intervention. In all patients, severity of the pain was evaluated by ocher questionnaire at recovery, and 3, 6, 12 and 24 hours after surgery. The data were analyzed using ANOVA and the repeated measures ANOVA (SPSS version 17).
RESULTS
The repeated ANOVA showed a significant decreasing trend of pain scores during the study for both pain scales (p 0.05). No statistically significant difference in pain was detected among the groups.
CONCLUSION
Although honey can help the pain decrease, more research is supported for confirmation of this effect
Interacting gravity with modified Chaplygin gas
In this paper, we have studied gravity as an arbitrary function of
curvature and torsion scalars in Friedmann--Lema\^{\i}tre--Robertson--Walker
(FLRW) background. Then, we have considered interacting model between
gravity and modified Chaplygin gas. The novelty of this model is that the
Universe includes both cases curvature and torsion, and one dominated by a
Chaplygin gas. In order to calculate cosmological solutions, we obtained
Friedmann equations and also equation of state (EoS) parameter of dark energy.
By employing interacting model we considered the total energy density and the
total pressure of Universe as the combination of components of dark energy and
Chaplygin gas. Subsequently, we reconstructed the model by an origin of a
scalar field entitled quintessence model with a field potential. The field
potential has been calculated in terms of free parameters of gravity
and modified Chaplygin gas. In what follows, we used a parametrization, and the
cosmological parameters have been written in terms of redshift . Next, we
plotted cosmological parameters with respect to three variable of cosmic time,
redshift and -folding number , and the figures showed us an
accelerated expansion of Universe. Also, we have described the scenario in
three status early time, late time and future time by -folding number.
Finally, the stability of scenario has been investigated by a useful function
named sound speed, and the graph of sound speed versus -folding number has
been showed us that there is the stability in late time.Comment: 16 pages, 5 figures. arXiv admin note: text overlap with
