Perception of God and Paranoia among Iranian University Students  [PDF]
Shideh Fasahati, Seyed Mohammad Kalantarkousheh
Psychology (PSYCH) , 2014, DOI: 10.4236/psych.2014.58109
Abstract:

This study examined the correlation between types of perception of God and paranoid thoughts among 312 randomly sampled students—175 female and 137 male—in the Azad Islamic University of Tehran in Iran. Two survey questionnaires were administered to the participants through the University’s website—one assessing their perception of God (Lawrence, 1997), and the other to assess the occurrence of paranoid thoughts among them (Derogatis, Lipman, & Covi, 1973). Data were analyzed using correlation coefficients and regression methods. The results show that only the negative perception of God correlates with paranoia in both males and females, while the perception of God’s blessings in one’s life correlates with paranoid thoughts only among male students. Students with a positive perception of God experience less paranoia than students with negative perception of God—a finding that may actually suggest that positive spirituality/religiosity holds positive and therapeutic benefits for the paranoid.

Open Journal of Geology (OJG) , 2015, DOI: 10.4236/ojg.2015.59055
Abstract: Early carboniferous deposits of the Kalmard block, with various characteristics in different outcrops, are recognized by Gachal Formation. Generally speaking, this formation comprises of four different members (A, B, C and D), consisting of carbonate and evaporative rocks. Gachal Formation is composed chiefly of 55 meters sandstone and limestone interbedded with shale. According to the lithological and microscopic studies, Gachal Formation is deposited in beach, semi-restricted and open lagoon, shoal and open marine environments. Vertical changes of microfacies and the curve of its depth changes account for the high thickness of the facies of shoal and bar sub-environments and the low thickness of the facies of lagoon and open marine sub-environment as well. Gachal Formation rocks in Rahdar section are deposited in a low-anglehomoclinal ramplocated in southern Paleothysis Ocean. The carbonate-sandstone sequence inGachal Formation in Rahdar section is composed of a depositional sequence separated from each other by type 1 sequence boundaries. Deposits of this formation are separated from lower deposits by type 2 sequence boundary and fromKhan Group by unconformity. The sedimentary sequence identified in this formation points to the age of late Visean, conforming to Kaskaskia IV. The erosional boundary between Gachal and Khan Formations is relatively compatible with drop in sea level at Late Kaskaskia global scale.
Effect of Timing of Circumcision on Sexual Satisfaction and Function  [PDF]
Seyed Reza Hosseini, Mohammad Ghasem Mohseni
Open Journal of Urology (OJU) , 2011, DOI: 10.4236/oju.2011.11003
Abstract: Objectives: Male circumcision is a commonly-performed surgical procedure in the world. Currently, no consensus exists about the role of the foreskin or the effect circumcision on sexual satisfaction. All previous studies have evaluated the effect of adult circumcision on sexual function. In this study, we responded to “Does circumcision timing have different effects on sexual function?” Methods: Based on circumcision timing (receiving circumcision in less than 18 year olds or older than 18 year olds), the participants were divided into two groups. The following data and measurements were investigated: IIEF-5 score, sexual satisfaction, sexual activity [number of sexual attempt/week] and ability to achieve or maintain an erection. Results: Two hundred and fifty cases including 125 men were investigated in each group. The baseline demographic (age, marital status, education, smoking) was similar in the 2 groups. No statistically significant differences were seen regarding their sexual satisfaction (P = 0.65), sexual activity [number of sexual attempt/week] (P = 0.74), ability to achieve or maintain an erection (P = 0.44), (P = 0.9). The total mean IIEF-5 score was 24.21 +/- 1.94 and 22.23 +/- 1.12 in groups 1 and 2, respectively (p = 0.5). Conclusion: We concluded that the age at which the circumcision is preformed has no effect on the degree of sexual function and satisfaction.
MAC Sub-Layer Analysis with Channel Estimation in Broadband Power Line Communication  [PDF]
Mohammad Khaled Andari, Seyed Ali Asghar Beheshti
Communications and Network (CN) , 2011, DOI: 10.4236/cn.2011.33017
Abstract: Broadband power line communication (BPLC) gained a lot of interest because of low cost and high performance communication network in access area. In this paper physical (PHY) layer and medium access control (MAC) sub-layer of BPLC are considered. Furthermore, effects of bit error rate (BER) are analyzed in MAC sub-layer. Powerful turbo convolutional code (TCC) and wideband orthogonal frequency division multiplexing (OFDM) are used in PHY layer. Carrier sense multiple access (CSMA) and virtual slot multiple access (VSMA) are taken into consideration in MAC sub-layer. Multilayered perceptrons neural network with backpropagation (BP) learning channel estimator algorithm compare to classic algorithm in for channel estimating. The simulation results show that the proposed neural network estimation decreases bit error rate then in MAC sub-layer throughput increases and access delay is decreased.

Seyed Abdolhossein Mehdi Nasab, Mohammad Pipelzadeh
Open Journal of Medical Imaging (OJMI) , 2011, DOI: 10.4236/ojmi.2011.12008
Abstract: Osteoid osteoma is a benign bone forming tumor of the growing skeleton that is most often seen in young men. It represents by pain and radiologic appearance of anidus surrounded by osteosclerosisthat occurs mostly in long bones of the lower extremity. Occurrence of this tumor in the hand is an uncommon condition. We present a 23-year-old man with an osteoid osteoma in the proximal phalanx of the right index finger. The radiological examination showed a lytic lesion with irregular border with a central sclerotic nidus and also sclerotic changes around the lytic lesion and bone expansion in the proximal phalanx of the right index finger. He was suffering from a history of pain and swelling of his finger since 8 months. The pain disappeared after surgical excision of nidus. The patient was pain-free and there was no evidence of recurrence at 15 months follow up.

Lead in Karvandar River Basin Sediment, Sistan and Balouchestan, IRAN  [PDF]
Javad Shahraki, Mohammad Javad Javdan, Seyed Mahmood Pahlavan Hashemi, Mohsen Jami, Mahdiyeh Nastooh, Seyed Mohammad Kalvandi
Open Journal of Geology (OJG) , 2015, DOI: 10.4236/ojg.2015.58048
Abstract: Streambed-sediment samples were collected in the Karvandar River Basin in the Sistan and Balouchestan province to determine the occurrence and distribution of lead in urban/rural and nonurban/rural areas of the basin. During fall 2012 and fall 2013, streambed sediment was collected at 30 sites, and the samples were analyzed for lead. The ranges in concentrations of lead in streambed sediments at urban/rural sites were orders of magnitude higher than the ranges of concentrations at nonurban/rural sites. Concentrations of lead at sites with different geologic settings were considered to be not statistically significant (t = 0.079, p = 0.93); however, concentrations of lead at these sites can be compared without substantial effects of natural geologic characteristics. Lead in streambed sediment was at concentrations that can adversely affect the aquatic biota in 48 percent of the urban/rural sites in the basin for both particle-size fractions. Lead concentrations in the <43 μm fraction were higher than the total particle-size fraction. Distribution patterns for lead indicate that grossly contamination (>SEL) does not exist throughout the entire drainage basin. A comparison between the sites close to the source and sites downstream indicated that the pattern of increasing concentrations was observed for lead with increasing distance from the source.

Javad Shahraki, Mohammad Javad Javdan, Seyed Mahmood Pahlavan Hashemi, Mohsen Jami, Mahdiyeh Nastooh, Seyed Mohammad Kalvandi
Open Journal of Geology (OJG) , 2015, DOI: 10.4236/ojg.2015.58049
Abstract: Early Permian deposits in north of Kalmard region recognize with formal group of Khan; they have various features in the different place. This group includes four different formations from lower to the upper part: Chili, Sartakht and Hermez. These formations consist of carbonate rocks. Chili Formation has 104 m, thickness in Darin section and consists of limestone with intermediates of shale and marland sandstone. Lower boundary of this formation is disconformable with Gachal formation. The upper boundary is separated by unconformity from the upper part Sartakht formation according to the lithological characters and microscopic studies, cause identifications of beach, intertidal, open and semi-restricted lagoon, shoals and bar and open marine sub-environ- ments for the Chili Formation. Vertical changes of microfacies and depth changes curve show much more thickness of shoals and bar microfacies, and little thickness of open and semi-re- stricted lagoon and open marine microfacies. Deposits of Chili Formation in Darin section deposited in the gentle gradient Homoclinal ramp in the south of Paleotethys Ocean. Two depositional sequences have been identified in this formation, based on recognized Fusulinid, show age of Sakmarian, which has adaptation with Lower Absaroka III.
