This study was conducted to investigate the relations between sensation seeking and stress among students of Bandar Abbas. Methods: In this cross sectional study, 400 students who had all the enrollment criteria were chosen by cluster sampling. A questionnaire was used to collect data. Results: The study showed that the mean excitement score was 16.66 ± 3.39 and with a maximum score of 27 and a minimum score of 8. Also, the mean score of experiment seeking was 7.70 ± 1.86 with a maximum score of 13 and a minimum score of 3. The mean score of tolerance towards boredom was 2.22 ± 1.3 with a maximum score of 9 and a minimum of 0. The mean score of escape inhibition was 1.34 ± 0.226 (max:2, min:0). Among all the participants, 35.3% had a moderate sensation seeking and above, and 71% had moderate stress. Conclusion: According to the results of the study, sensation seeking had no significant associations with stress.
Background: The Domesticated silkworm, Bombyx mori, an economically important insect has been used as a lepidopteran molecular model next only to Drosophila. Compared to the genomic information in silkworm, the protein-protein interaction data are limited. Currently various high throughput methods are in vogue to identify protein-protein interactions but none of these methods are applied to silkworm. Therefore information on protein-protein interaction network in silkworm is essential for further understanding of the cellular processes. The silkworm protein sequences were obtained from the SilkDB database and the experimentally identified PPI maps from five model organisms such as E.coli, C.elegans, D.melanogaster, H. sapiens, S. cerevisiae were used to infer the PPI network of silkworm using the well-recognized Interlog based method.\nResults: Totally 7736 protein-protein interaction pairs were predicted among the 14623 silkworm proteins which include 2700 unique proteins of the silkworms. These were validated using the iPfam interaction domains and the gene expression data. Totally 625 PPI pairs of predicted network were associated with the iPfam domain-domain interactions and the random network has average of 9. In the gene expression method, the average PCC value of the predicted network and random network was 0.29 and 0.231±0.00042 respectively. It reveals that the predicted PPI networks of silkworm are highly significant and reliable. \nConclusions: The predicted silkworm protein-protein interaction data are available at SilkPPI (http://210.212.197.30/SilkPPI/). This is the first PPI network for the silkworm which will provide a framework for deciphering the cellular processes governing key metabolic pathways in the silkworm, Bombyx mori.
The purpose of this study was review the existing literature on coaches’ sources of knowledge in various sports. The review highlighted coaches’ knowledge is built from a broad range of sources. It is influenced by a complex mix of formal, non-formal, informal directed and self-directed learning experiences. However, this developmental mix for coaches is largely individualized and ad hoc. While the literature suggests the balance tends to be toward informal learning, the optimal mix of learning experiences needs to be addressed. In this respect, the researches available on coaching knowledge are limited by a tendency to focus on expert or elite coaching practitioners. This group of coaches has been shown to favor self-directed learning and therefore engage in activities to match.
Iranian people were hopeful to have the activities and systematic economical, social and political relations in constitutional revolution by forming the versed in law/law abiding administration and their participation in administering/managing the society affairs. A look in the achievements of the constitutional revolution in stabilizing the political administration and beginning the rule of Reza Shah indicated that the formation of political power in Iran is the result of fundamental elements and the politico-economical conditions of the society. The worlds’ economical system was not ineffective on the formation trend of political, social and economical currents of Iran. The worlds’ economical system caused the Old Iranian economy could not move towards self-sufficient, inborn, dynamic and stable economy. This should be noticed that formation and continuance of one way management is a multidimensional phenomenon under internal effective factors more than that of resulting from external factors. The results obtained from this article indicate that the political structure of Iran during Ghagar period that was under the influence of social rifts and interferences (including the religious, population and racial inequalities etc) on one hand and the simple tribal structure on the other hand, prevented the formation of foundations/institutions and desired political structure. The political culture that resulted from this political and social structure didn’t provide the opportunity to activate the society in the political activities.
To investigate the effect of substrate on some parameters of ornamental plant experiment Atlas of Iran 2011-2012 in greenhouse located at Km 10 North Road Zahedan - Khash in a factorial randomized complete block design with 5 replications. Factors examined include various levels of zeolite and vermicompost (0, 5 and 10 percent).Iranian petunia seeds in pots and grown to flowering stage was studied in the liter. The results showed that the chlorophyll A content increased with increasing zeolite has a direct relationship. Chlorophyll B in 5% zeolite shows the highest. Effect of zeolite shows the main elements of K and N decreases with increasing zeolite . The amount of phosphorus in the root level and the highest 10 % of the lowest value indicates the level of 5 % . The study showed that nitrogen and phosphorous and 10 % at the highest level and was not significantly different at 0 and 5 % .But at 5% potassium zeolite showed the highest values .Chlorophyll A in the 10 % highest and 5 % lowest level displays . However, chlorophyll B decreases with increasing levels of vermicompost. The amount of N and P in roots increased with increasing levels of vermicompost . , But the rate of increase in K indicates the amount of vermicompost element has an inverse relationship . Vermicompost on shoot N concentration element has an inverse effect .P values of 5 % and a maximum of vermicompost at 5% level represents the lowest. Final results showed that compared with zeolite , vermicompost effect on the economic growth factors and is more affordable .
Data aggregation protocols are required in Wireless Sensor Networks (WSNs) to extend the network lifetime by reducing the energy consumption. The existing DAO-LEACH (Data Aggregation-Optimal LEACH) protocol for WSN is insecure and prone to false data injection. This is enhanced in terms of security and fault-tolerance based on Gracefully Degraded Data Aggregation (GDDA) to ensure the integrity of the aggregated data and Hybrid Layer User Authentication (HLUA) to ensure the confidentiality of the aggregated data. This data aggregation scheme rejects the false data from compromised and malfunctioning sensor nodes (SNs). HLUA consists of a combination of Secret Key Cryptography (SKC) method such as MAC (Message Authentication Code) algorithm and Public Key Cryptography (PKC) method such as Elliptic Curve Cryptography (ECC). MAC algorithm is used between the cluster heads (CHs) and SNs to fulfill lower power demand, while ECC is applied for User Authentication (UA) between CHs and users. The enhanced DAO-LEACH protocol is resistant to security attacks such as, replay attacks, node compromising attacks, and impersonation attacks. It performs better in terms of energy consumption, number of alive nodes, end-to-end delay (EED), and false data detection, compared to SCAR (simple cluster-based data aggregation and routing), ESPA (Energy-efficient Secure Path Algorithm), DKS-LEACH (deterministic key management based LEACH), SEDAN (Secure and Efficient Data Aggregation protocol for WSNs), and DAA (Data Aggregation and Authentication).
Compression of large collections of data can lead to improvements in retrieval times by offsetting the CPU decompression costs with the cost of seeking and retrieving data from disk. In this paper, the author has study the different compression method which can compress the large DNA sequence. In this paper, authors have explored the DNA compression method that is COMRAD, which is used to compare with the dictionary based compression method i.e. LZ77, LZ78, LZW and general purpose compression method RAY. In this, authors have analyzed which one algorithm is better to compress the large collection of the DNA Sequence. Compression table and the line graph show that which compression algorithm has a better compression ratio and the compression size. It also shows that which one has better compression and decompression time.
