The image of nursing, as perceived by Iranian male nurses

The stereotypical public image of nursing is a major concern for male nurses around the world. In this study, we explored how Iranian male nurses perceived the public view of nurses, and their perceptions of themselves. A qualitative descriptive design and content analysis were used to obtain data from 18 purposely-selected male hospital nurses with a baccalaureate nursing degree in Tabriz, Iran. Semistructured interviews were conducted and analyzed. Two main themes emerged: (i) the outsider's view of nursing, which referred to the participants' perceptions of their public image; and (ii) the insider's view, which related to the male nurses' perceptions of themselves. Results included personal transition into a positive professional self-image through the educational process, and continued public perception of nursing as a female profession ill-suited for a man. Strategies to improve the insider's and outsider's views of nursing are listed to help recruit and retain more Iranian male nurses

Holomorphy in convergence spaces

We introduce a new approach to infinite dimensional holomorphy. Cast in the setting of closed-embedded linear convergence spaces and based on a categorical definition of derivative, our theory applies beyond the traditional open domains. It reaches certain domains with empty interior (that arise naturally in Fréchet spaces) and gives a fully fledged differential calculus. On open domains our approach provides a new characterization of holomorphic maps. Thus earlier theories become expanded as well as strengthened

Holomorphic maps on domains with empty interior

We bring to light further infinite dimensional domains with empty interior on which holomorphic maps can be constructed

Fault-tolerant control of 3-phase im drive (speed-sensor fault and open-phase fault)

In this paper, a fault-tolerant control strategy dedicated to star connected 3-phase Induction Motor (IM) is presented. The presented method is able to control 3-phase IM drive under healthy, speed-sensor fault and open-phase fault conditions. The proposed fault-tolerant control system is derived from an Extended Kalman Filter (to compensate speed-sensor fault) and two developed Field-Oriented Control (FOC) algorithms (to compensate open-phase fault). The performance demonstrated by the simulation results shows that, in comparison with conventional FOC, the proposed approach, provides an accurate vector control and good dynamic performance particularly in reduction of motor speed and torque oscillations

Analytical calculation of the RFOC method in single-phase induction motor

This study discusses the different techniques for speed control of single-phase induction motor with two asymmetrical main and auxiliary windings based on Rotor Field-Oriented Control (RFOC) method. In the presented methods, transformation matrices are introduced and applied to the equations of single-phase induction motor. It is shown by applying these rotational transformations to the unbalanced equations of single-phase induction motor, equations of single-phase induction motor are transformed into symmetrical equations. These rotational transformations are achieved based from the steady-state equivalent circuit of single-phase induction motor. Finally, a method for RFOC of single-phase induction motor is proposed. Results show the good performance of the proposed method

Evaluation of the Frequency and Type of Damages to the Ears, Nose and Throat in Patients Referring from Forensic Medical Centers to Ayatollah Rohani Hospital in Babol, Iran in 2012

BACKGROUND AND OBJECTIVE: Currently, trauma is regarded as one of the most serious problems in societies, resulting in irreversible damages and injuries in individuals. Trauma as a result of assault, injury or accident is of grave significance, especially in developing countries. The purpose of the present study was to evaluate the frequency and type of injuries to the ears, nose, and throat in patients referring from forensic medical centers to Ayatollah Rohani Hospital in Babol, Iran. METHODS: In this cross-sectional study, patients referring from Babol forensic medical centers were examined by an otolaryngologist in 2013. In this study, the cause and type of damages, as well as demographic characteristics, were collected and recorded in a checklist.  FINDINGS: In total, 238 cases were included in this study. The mean age of participants was 35.40±11.58 years. The majority of subjects were within the age range of 18-44 years. Ear damage was one of the common complaints in 146 subjects (61.34%). Overall, 94 cases (39.5%) had left ear injuries, 35 cases (14.7%) had right ear injuries and 17 cases had experienced damages to both ears. Dispute and assault were the major causes of hospital admission in 158 patients. CONCLUSION: According to the results of this study, the highest incidence of trauma was reported in young individuals because of dispute and assault. Therefore, the dispute and assault are decreased in youths by preventing the effective agents

Studying the effect of vitamin d on the intensity of torsional nystagmus in Benign paroxysmal positional vertigo (BPPV) in Rohani hospital of Babol

Background: Benign paroxysmal positional vertigo (BPPV) is the most common cause of vertigo and nystagmus in clinics. Vertigo has many causes and the recurrence of vertigo is unknown. Among a lot of factors, vitamin D deficiency is more important. This study was conducted to determine the effect of vitamin D supplementation on torsional nystagmus in BPPV patients. This study wants to show the deficiency of vitamin D leads to the recurrence of BPPV. Methods: This case-control study was conducted from April 2017 to May 2018. All eligible patients with BPPV were presented to the Audiology clinic of Babol Rouhani hospital consecutively. Diagnosis of BPPV and the presence of nystagmus were confirmed and serum vitamin D was assessed. Dix-halpike maneuver and videonystagmography (VNG) for assessing nystagmus were done and for serologic assessment, ELISA was performed for analyzing the level of hydroxy 25 vitamin D.Vitamin D sufficient patients (more than 20 ng/ml) with BPPV were considered as the control group and vitamin D deficient patients (less than 20 ng/ml) were as the test group. In all the patients of two groups, torsional nystagmus (vertical, horizontal and oblique) were studied and compared. Results: Twenty-seven patients in each group have completed the study. The mean age of the control group and test group was 48.2+4.8, 47.8+5.7 and 47.2+4.9 years respectively (P=0.91). Two groups were comparable regarding nystagmus severity. All patients had at least two attacks During the last six months. The mean of serum 25 OHD was 33.81 in the control group and 11.41 in the test group that was statistically significant (P=0.001 for all) and the severity of torsional nystagmus in three axes of horizontal, vertical and oblique in the control group was 4.98, 9.06, 5.40 respectively and 3.32, 8.86, 6.93 in the test group that was statistically significant as compared with the control group (P=0.001). Conclusion: Findings of this study indicate a relationship between vitamin D deficiency and recurrence of nystagmus in BPPV patients. © 2021 Tehran University of Medical Sciences.

Speed estimation of faulty three-phase induction motor using model reference adaptive system

In this paper, a method for speed estimation of faulty three-phase induction motor (three-phase induction motor under stator winding open-phase fault) based on Model Reference Adaptive System (MRAS) is presented. The proposed method can be used for both healthy and faulty induction motors. In this method during normal condition the conventional MRAS is used to estimate motor speed. However, during the fault condition the conventional MRAS is switched to the novel algorithm based MRAS. This novel algorithm is designed based on the model of three-phase induction motor under open-phase fault. Simulation results are presented to show the effectiveness of the proposed technique. This paper also compares the performance of conventional and proposed MRAS during open-phase fault
