Abstract: The aim of the study is to examine the technical and security conditions of state vessels traveling to Bushehrports. This research is filled out through a 22-item questionnaire by 40 security and controlling officers of Bushehrvessels. The results of Kolmogrov-Smirinov test suggest that the data are normal and T-test has been used for questionnaire analysis. The findings indicate that failure in technical and security certificates, failure of qualification certificate, failure of machinery and electrical appliances, structural safety defects, failure of telecommunication equipment, failure of security in under 500 tons motor boats and traditional and metal vessels [1]. As well, above 500 tons vessels traveling to Bushehr waters (state vessels) have suitable conditions.

Abstract: The present research examined the effect of speech rate on listening comprehension of Iranian EFL learners. Initially, a sample of 108 sophomore EFL learners majoring in English translation was selected based on systematic random sampling from Abadan Islamic Azad University. Then, based on an ECCE proficiency test, 62 participants were chosen and divided into two homogeneous groups of 31. One group had exposure to natural speech rate and the other to slow speech rate of listening materials. After thirteen academic sessions, the results o the paired t-test regarding the pre-tests and post-tests of the two group means showed that both differences (group one: –2.83 and group two: –1.22) were significant at 0.05 levels (P < 0.05). These findings suggest that each speech rate, whether natural or slow, could improve EFL learners listening comprehension; however, natural speech rate could demonstrate greater improvements than slow speech rate in EFL learners’ listening comprehension.

Psychology (PSYCH) , 2011, DOI: 10.4236/psych.2011.25065
Abstract: Undoubtedly mind is the most complicated member of human being and respectively a small breakdown in whatever processes undergone will cause great difficulties for the beholder. One of the most serious psychological impairments is known as schizophrenia which severely distorts thought and action (Hockenbury & Hockenbury, 2004). The present study is set out to investigate the capability of patients with schizophrenia in doing different vocabulary tasks on second language and retaining them for a period of time. Eight male patients diagnosed with schizophrenia of different types were selected from two mental centers to participate in the study. They were invited to attend a class for 16 sessions in 8 weeks and do vocabulary tasks including matching words to the pictures, filling the blanks, word association, crossword puzzle, and word finding. A test was administered right after the period and the retest was administered 16 days later. The study illustrated that there is no significant relationship between age and learning vocabulary items by patients suffering from schizophrenia. More, schizophrenics showed different capabilities in doing vocabulary tasks, and they also showed different impairments in their attempt to learn foreign language words. They also found some of the tasks demanding as they become more cognitively difficult.

Abstract: Proton pump inhibitors often are prescribed in combination with clopidogrel to decrease risk of gastrointestinal bleeding after acute coronary syndrome. Clopidogrel is a prodrug that has to be metabolized in the liver to generate the active metabolite. Both medications are metabolized largely by the CYP2C19 enzyme; therefore, concerns exist that a drug-drug interaction during concomitant treatment with clopidogrel and a proton pump inhibitor may result in reduction of platelet inhibition. We have reviewed observational and randomized control studies that have evaluated the potential influence of proton pump inhibitors on the platelet inhibitory effect of clopidogrel, along with cardiovascular outcomes. We also have summarized regulatory and academic guidelines for treatment of patients in which concomitant therapy with clopidogrel and proton pump inhibitors may be indicated. Confounding issues, including differential effects of individual proton pump inhibitors on the pharmacodynamics of clopidogrel and variation in clopidogrel metabolism mediated by CYP2C19 gene polymorphisms, also are discussed.

Abstract: To evaluation of pathogenicity and race classification of Xanthomonas oryzae pv. oryzae agent bacterial leaf blight of rice, 153 isolates of X. oryzae pv. oryzae were collected from different rice-growing cities of Guilan province – Iran. All of isolates were inoculated to assess the differential characteristics of 26 near isogenic rice lines containing a single resistance gene or two to five genes. Inoculation was done 21 days after sowing in the greenhouse. Scoring of inoculated plants was done 18 days after inoculation. The level of infection was not so clear among pyramiding lines, expect IRBB53 and IRBB61. Therefore, the pyramiding lines can not be used as differentials for pathogenicity evaluation of X. oryzae pv. oryzae The 12 rice lines with a single resistance gene were used further to establish a system of races classification of X. oryzae pv. oryzae IRBB14, IRBB21and IRBB7 were resistance to the most isolates. Whereas, IRBB1, IRBB2, IRBB4 and IRBB10 were susceptible to all isolates. Based on the interactions between the isolates X. oryzae pv. oryzae and the 12 near-isogenic rice lines, seven singlegene rice lines were chosen as differentials, and the 153 tested isolates were classified into four races. Except for cultivar types, different terrain, climate, period of rice planting and other factors may be associated with the population diversity and virulent variation of X. oryzae pv. oryzae.

Abstract: Parkinson’s disease (PD) is the most common disease of motor system degeneration that occurs when the dopamine-producing cells are damaged in substantia nigra. To detect PD, various signals have been investigated, including EEG, gait and speech. Since approximately 90 percent of the people with PD suffer from speech disorders, speech analysis is considered as the most common technique for this aim. This paper proposes a new algorithm for diagnosing of Parkinson’s disease based on voice analysis. In the first step, genetic algorithm (GA) is undertaken for selecting optimized features from all extracted features. Afterwards a network based on support vector machine (SVM) is used for classification between healthy and people with Parkinson. The dataset of this research is composed of a range of biomedical voice signals from 31 people, 23 with Parkinson’s disease and 8 healthy people. The subjects were asked to pronounce letter “A” for 3 seconds. 22 linear and non-linear features were extracted from the signals that 14 features were based on F0 (fundamental frequency or pitch), jitter, shimmer and noise to harmonics ratio, which are main factors in voice signal. Because changing in these factors is noticeable for the people with PD, optimized features were selected among them. Of the various numbers of optimized features, the data classification was investigated. Results show that the classification accuracy percent of 94.50 per 4 optimized features, the accuracy percent of 93.66 per 7 optimized features and the accuracy percent of 94.22 per 9 optimized features, could be achieved. It can be observed that the best classification accuracy may be achieved using Fhi (Hz), Fho (Hz), jitter (RAP) and shimmer (APQ5).

Abstract: According to August 1996 records the last official status of Chechnya was postponed till 2001. Until that time Chechnya would be accepted independent in the presidency of Aslan Mashadov, the official general. However, this defeat was disgraceful according to Moscow and it was just a war that each side desired to revenge and test each other. The appointment of Putin, who was being more ambitious and aggressive than the others, foreshadowed the new applications to be implemented by the army. In September 1999, a series of bombings in the Moscow apartments caused the deaths of many people and caused property damage, which was used as a reason for the shady accusation of Chechnya. The government blamed the Chechen separatists for attacking areas of rebellion. The victory of the Russian forces fighting the guerrilla opposition forces destroyed the capital Grozny and other cities.

Abstract: Eucalyptus oil business is one of the dominant sector of forestry/agriculture in the regency of Buru. At least there are more or less 1.939 workers in this industry whose livelihood depends on it. This sector is also the one with the greatest prospect in supporting the economy of the Buru regency. The routines of eucalyptus oil refining by farmers in the regency of Buru is part of the economic activities which have been carried out for generations. As a business which has been handed down for generations, the role of farmers is very important,that is as the supplier of production factors, supplier of labor and other equipment. The implication of farmers' position as owner has created a problem due to the role of the parties to eucalyptus oil business contract. This phenomenon has created a bias on the principal-agent problems since the actors related to the contract have imbalanced capacity. This study aims at investigating the role of parties to eucalyptus oil business contract. Using institutional economics approach, the findings of this study are: (1) the business contract has not placed the farmers in a position as principal but instead as worker/laborer (agent); (2) the ownership over asset (village/land), labor and means of production and others is not sufficient to bring adequate bargaining power to the farmers.

Asian Journal of Plant Sciences , 2004,
Abstract: Sixteen different Helianthus annuus L. hybrids growing in Turkish Trakya region were included in this study. Three different methods were employed. While germination occurred in the first method following surface sterilization which was done without removing the testa, in the second one surface sterilization was done by removing the testa. Unlike these, however, in the third one, germination occurred in moist cotton media without removing the testa. Culture experiments were done in various media with varying hormone concentrations by using different explants of the obtained samples. Productive results were obtained in cultures in which cotyledon and hypocotyl explants were used. When sections of these explants were investigated, regeneration and callus formation were found to differ between native and hybrid types.
