Survey of Relationship between Personality Traits with Mental Health and Academic Staffs’ Job Satisfaction in the University of Guilan, Iran

The main aim of the research is survey of relationship between personality characteristics with academic staffs’ job satisfaction and mental health in the University of Guilan. The statistic population was all these academic staffs in the year of 2014 (500). 196 individuals have selected by Kerjecy & Morgan (1970) and random sampling method. The research instruments were personality characteristics (NEO), General Health Questionnaire (GHQ) and self-made questionnaires. Pearson’s Correlation, Multiple Regression and Multiple Variant (Manova) have used for analyzing data. Results showed that there was a relationship among neurotic and settlement’s personality characteristics with job satisfaction and neurotic, openness, extroversion personality characteristics and settlement with mental health. Some of personality characteristics had been anticipators of mental health and job satisfaction and personality characteristics with mental health and job satisfaction had differenced depend on sociologic variances relationships.

Biotransformation of Carmoisine and Reactive Black 5 Dyes Using <i>Saccharomyces cerevisiae</i>

Saccharomyces cerevisiae (baker’s yeast) is the most important industrial microorganisms. This yeast is commonly used as a leavening agent in baking bread and bakery products, where it produces carbon dioxide from converting of the fermentable sugars present in the dough. Nowadays, industrial and chemical activities led to produce new compounds with new kinds of contamination in the environment. Discharge of untreated or partially treated industrial sewage has created the contamination problems of rivers and lakes such as drugs, oil, heavy metals, paints, pesticides and various chemical compounds in them. Hence, it is necessary to control and reduce the levels of these compounds in wastewater and bring them to permissible values. This study aims to study the bioconversion potential of commonly available Saccharomyces cerevisiae for the two textile dyes of Carmoisine and Reactive Black 5. Reaction mixtures for biotransformation of dyes included 50 mg/l Carmoisine or 25 mg/l Reactive Black 5 and 1% dried harvested cells of S. cerevisiae (bread’s yeast) were tested. Harvested dry and wet yeast were studied for this purpose. The results show that harvested cells of Saccharomyces cerevisiae are able to bioconvert Carmoisine and Reactive Black 5. Reactive Black 5, Carmoisine are degraded by biotransformation 85% and 53% within 24 hours in water at the room temperature.

The Role of Life Orientation and Cognitive Regulation on Decreasing Job Stress

The aim of this study is to investigate the relationship between life orientation and cognitive emotion regulation with job stress. On this basis, a sample of 100 employees working in Guilan Education Office was used and research hypotheses were examined by job stress, life orientation and cognitive emotion regulation questionnaires. The results of this study indicate that job stress has a significant relationship with life orientation (-0.32), self-blame (0.25), rumination (-0.36), positive refocusing (0.25), positive refocusing on program (-0.21), positive reappraisal (-0.28), catastrophizing (-0.39) and other blames (-0.25). Furthermore, life orientation and cognitive regulation could explain 22% variances in respondents’ job stress. This finding indicates that more positive life orientation and subsequent decrease of emotion-regulation-related disorders will lead to less job stress.

Relationship between Students’ Personality and Mental Health at University of Guilan (Faculty of Humanities)

The main goal of this research was the scrutiny of relationship between students’ personality characteristics and mental health at the University of Guilan. The population was the students of the Faculty of Humanities in 2009 with 3000 which 196 were selected using Kerjeci & Morgan table and stratified sampling method. They answered to the NEO and GHQ questionnaires. Results showed that there was relationship between personality characteristic of neurotic, openness, extraversion and being conscionable with mental health. Meanwhile, openness had the highest and extraversion with the lowest correlation scale and most of students (65%) had low mental health. Also, there were no significant differences among students with respect to different courses but significant difference with respect to gender and age.

Paleoceanography and Paleobiogeography Patterns of the Turonian-Campanian Foraminifers from the Abderaz Formation, North Eastern Iran

In this research, the Turonian-early Campanian sedimentary succession of the Abderaz Formation with 510 mthick (comprising: light grey shale and marls) was studied in the type section in eastern Kopeh-Dagh basin. The statistical analysis of the morphotype groups of the identified planktonic foraminifers shows that most of them are shallow water forms (SWF) and deep water forms (DWF). The high planktonic to benthic ratio indicates particular oligotrophic conditions and sedimentation in relatively deeper zones of a marine environment. The salinity of sea water during Coniacian was in the minimum level, whereas it reached maximum in Coniacian-Santonian boundary. Comparing Planktonic assemblages from the study formation with those from the Cretaceous biogeographical provinces reflects a close relationship between the identified species and the planktonic forms of the Tethyan provinces.

Biostratigraphy and Mass Extinction Pattern across the Cretaceous/Paleogene Boundary, Northern Alborz, Iran

High resolution sampling across the Cretaceous/Paleogene boundary (K/Pg) at the Galanderud section in northern Iran provides the most expanded and continuous section for us to consider biostratigraphy and the mass extinction pattern of Cretaceous planktic foraminifera. Based on planktic foraminifera, four biozones and five sub-biozones have been identified across the K/Pg boundary. These biozones include the Abathomphalus mayaroensis Biozone (Plummerita hantkeninoides subbiozone), the Guembelitria cretacea Biozone (including two sub-biozones: the Hedbergella holmdelensis and the Parvularugoglobigerina longiapertura), the Parvularugoglobigerina eugubina Biozone (including two subbiozones: the Parvularugoglobigerina Sabina and the Eoglobigerina simplicissima) and finely the Parasubbotina pseudobulloides Biozone. Planktic foraminiferal extinction occurred over a brief period, with 3% of the species disappearing in the late Maastrichtian, and 72% of the species becaming extinct at the K/Pg boundary. About 25% of the species survived into the early Danian. Extinction of 73% of the species at the K/Pg boundary is very compatible with the effect of a large asteroid impact.

Sequence and Biostratigraphy of Lower Cenozoic Succession in the Kopet-Dagh Basin, NE of Iran

The main purpose of this paper is the sequence stratigraphy and biostratigraphy of lower Tertiary sediments on the base of larger benthic foraminifera in northeast of Iran (Chehel-Kaman Formation). This formation mainly consists of Limestone, dolomite and interbeds of sand, shale and evaporate sediments. Petrographical studies indicate that these sediments may have been deposited on a shallow carbonate platform ramp and consist of 4 carbonate lithofacies (15 subfacies). These lithofacies may have been deposited in open marine, shoal, lagoon and tidal flat environmental conditions. Sequence stratigraphy analysis led to identification of 4 third-order depositional sequences, bounded by type 2 (within the top of the underlying Pestehleigh Formation) and type 1 sequence boundaries (paleosol). Interpreted sea level curve in this basin can be relatively correlated with global curves during Paleocene time and a with a sea-level fall occurred in the latest Paleocene, followed by a rise in the earliest Eocene. Biostratigraphy study led to the identification of 32 larger benthic Foraminifera genera. The Paleocene/Eocene boundary has been probably recorded as a thin red paleosol horizon (~10 - 15 cm).
