The relationship between cognitive flexibility and cognitive fusion with the borderline personality disorder symptoms

Since researches have shown that maladaptive cognition plays a role in the beginning and maintenance Borderline Personality Disorder (BPD), this research aims to evaluate the relationship between cognitive flexibility and cognitive fusion with borderline personality disorder symptoms. 356 students of Mazandaran University of Medical Sciences who studied in the academic year of 2017-2018 were selected using cluster sampling method and they completed Cognitive Flexibility inventory (CFI), Cognitive Fusion Questionnaire (CFQ) and Schizotypal Trait Questionnaires (STB). There was a positive and significant relationship between cognitive fusion and borderline personality disorder (BPD) (p<0.01). The correlation between cognitive flexibility and borderline personality disorder and subscales was significant and negative (p<0.01, p<0.05). Cognitive flexibility and cognitive fusion and their subscales can predict the BPD factors. It is suggested that psychological interventions, especially cognitive-behavior therapy (CBT) and Acceptance and Commitment Therapy (ACT), are used to increase the cognitive flexibility and reduce cognitive fusion of students with borderline personality symptom

The Effect of Stock Migration on the Spend of portfolios’ Return

The purpose of this study is to investigate the effect of stock migrations on the spend of portfolios’ return. For this purpose, the return of portfolios that have migration for two consecutive courses was investigated. Due to the few studies in Iran, this issue has no clear and reliable results in Iran. This research can be complementary to studies by Fama and French, Khan Ahmadi and Tehrani. To test the hypotheses, portfolios based on accounting data from 2004 to 2016 were provided. In this research, sampling method is systematic elimination method and Alpha Jensen is used to study the constituted portfolios performance. According to the results of first, second and third hypotheses, there is not a significant relationship between return and stock migration. Meanwhile, there is a significant relationship between the variables of the forth hypothesis. Therefore, the wealth of stock holders increased by investing in companies that had migration from small size to big size in two consecutive courses

Conclusions: These results shows that PST will be effective in reducing depression and dysfunctional attitudes in among patients with Coronary Artery Bypass Graft surgery. Then PST is an effective intervention that can improve problem-solving abilities and mental health-related in CABG surgery patient

Toward Sustainable Tackling of Biofouling Implications and Improved Performance of TFC FO Membranes Modified by Ag-MOF Nanorods

In this work, nanorods with high antibacterial properties were synthesized with silver acetate as the metal source and 2-aminoterephthalic acid as the organic linker and were then embedded into thin-film composite (TFC) membranes to amend their performance as well as to alleviate biofouling. Silver metal-organic framework (Ag-MOF) nanorods with a length smaller than 40 nm were incorporated within the polyamide thin selective layer of the membranes during interfacial polymerization. The interaction of the synthesized nanorods with the polyamide was favored because of the presence of amine-containing functional groups on the nanorod's surface. The results of X-ray photoelectron spectroscopy, scanning electron microscopy, energy-dispersive X-ray spectroscopy, and atomic force microscopy characterizations proved the presence of Ag-MOF nanorods in the selective layer of thin-film nanocomposite (TFN) membranes. TFN membranes demonstrated improved water permeance, salt selectivity, and superior antibacterial properties. Specifically, the increased hydrophilicity and antibacterial potential of the TFN membranes led to a synergetic effect toward biofouling mitigation. The number of live bacteria attached to the surface of the neat TFC membrane decreased by more than 92% when a low amount of Ag-MOF nanorods (0.2 wt %) was applied. Following contact of the TFN membrane surface with Escherichia coli and Staphylococcus aureus, full inactivation, and degradation of bacteria cells were observed with microscopy, colony-forming unit tests, and disc inhibition zone analyses. This result translated to a negligible amount of the biofilm formed on the active layer. Indeed, the incorporation of Ag-MOF nanorods decreased the metal-ion release rate and therefore provided prolonged antibacterial performance

The Effect of Citrus Aurantium Aroma on Sleep Quality in the Elderly with Heart Failure

BACKGROUND AND OBJECTIVE: Poor sleep quality is one of the most common problems in the elderly with heart failure, and hospitalization exacerbates this problem. In traditional Persian medicine, citrus aurantium has been recognized as a sedative and inducer of sleep. The aim of this study was to determine the effect of citrus aurantium on sleep quality in the elderly with heart failure. METHODS: This randomized clinical trial was performed on 80 elderly patients with heart failure admitted in selected teaching hospitals of Mazandaran province in two intervention and control groups. In the intervention group, aromatherapy with two drops of 10 citrus aurantium essential oil was performed on a cotton ball for twenty minutes for three consecutive nights and the control group received routine care. Sleep quality of the elderly was assessed before and after the intervention using the standard St. Mary's Hospital Sleep Questionnaire (SMHSQ) (which assesses the quality of previous night's sleep in hospitalized patients).   FINDINS: The mean sleep disorder in the elderly before and after the intervention in the intervention group was 24.70±3.67 and 21.05±3.62, respectively, which was statistically significant (p=0.001). Mean sleep disorder in the elderly before and after the intervention in the control group was 24.37±4.48 and 23.75±4.71, respectively, which was not statistically significant. CONCLUSION: The results showed that using aromatherapy with citrus aurantium can improve sleep quality in the elderly with heart failure

Forward osmosis research trends in desalination and wastewater treatment: A review of research trends over the past decade

Issues of water scarcity and water security have driven the rapid development of various technologies to ensure water sustainability. The forward osmosis (FO) membrane process has been widely recognized as one of the more promising technologies to play an important role in alleviating the issues of water sustainability. Extensive research has been carried out worldwide to explore the potential of FO in desalination, water and wastewater treatment and reclamation. It is of the utmost importance to understand the topics of interest and research trends to further advance the development of FO process technology. In this study, a bibliometric analysis based on the Scopus database was carried out to identify and understand the global research trends of FO process based on 6 main analyses: basic growth trends, journals, countries, institutions, authors, and keywords. A total of 1462 article published between 1967-2018 were extracted from Scopus and used as the raw data for bibliometric analysis using VOSviewer software. The total number of FO articles has sharply increased since 2009 and stabilized at around 250 publications in the past three years. FO research started to diversify after the appearance of commercial FO membranes with improved characteristics, enabling the researchers to employ them for various application studies. Keywords analysis showed that the main directions of FO research could be categorized into three clusters: application of FO, membrane fouling study, and FO membrane synthesis. These bibliometric results provide a valuable reference and information on current research directions of FO for researchers and industry practitioners

mm-Wave Phase Shifters and Switches

The ever increasing speed of transistors in mainstream silicon-based technologies made the mm-wave domain open to consumer electronic applications. Solutions that previously had to be implemented in advanced compound (III-V) technologies and were limited to high-end systems due to cost purposes, are now entering the market of low-cost consumer electronic products. Emerging mm-wave market contains various applications from extremely high data rate transceivers in Personal Digital Assistant (PDA) devices to automotive radar modules and to point to point links for replacing the fiber connectivity in sparse areas. Chapter one highlights the specific requirements of each application that makes it more compatible with a certain type of technology.To have a complete mm-wave system suitable for low cost applications, a single chip or a single package solution is preferred. To achieve this goal integrated low loss transmit / receive switching structures that are highly linear should be employed. A miniature transformer-based shunt T/R switch is introduced and implemented in a standard 90nm CMOS technology. Design equations and trade-offs for such a structure are described in this thesis. Due to a much higher free space path loss of a 60GHz signal compared to its low frequency counterparts (30dB higher loss than WiFi), and lower performances extractable from devices at these high frequencies, phased antenna array structures should be exploited to add passive antenna gains to the transceiver and help meet the link budget requirement. Fundamentals of phased antenna array structures are described and two different implementations, one through true time delay elements and the other one employing phase shifters are presented. For wideband applications and for very large arrays intended to have a wide field of view, true time delay elements should be employed to steer the array pointing beam. This work investigates true time delay elements, and an inductance tuning technique is introduced which enhances the delay tunability of a synthesized transmission line while keeping its characteristic impedance constant. In most mm-wave applications, delay cells in antenna array structures can be approximated and replaced with phase shifters. Hence different types of phase shifters are studied and an active I-Q interpolating phase shifter in the RF-path is designed and implemented at 60GHz
