Study behaviour of selective racking systems in the crossaisle direction

This paper describes the behaviour of selective steel storage racking systems in the cross-aisle direction. Steel storage racks are regular kind of equipment; these systems are developed for enhancing the storage of load units in diverse weights and sizes. In most cases in this study, the boundary conditions assumed fixed on their fundamental state, to prevent from any possible moment – rotation and uplift effects on uprights. Finite element method (FEM) modeling was used to analyze and evaluate the natural frequency of diagonally k-braced frame at cross-aisle direction. This report takes advantage of capabilities of two well-known structural analysis software for FEM modeling: Abaqus and Strand7. The objective is to predict and determine the eigenvalues and natural frequencies of selective steel storage racks in the cross-aisle direction. Taking the fact into account that the reaction of the structure under seismic loads is vitally important at this critical direction, this paper will provide a better view for designing these type of structures in the future. The novelty of this paper is to classify conditions where we could avoid creating any possible resonance in the structure

Effect of Progressive Muscle Relaxation Technique on Fatigue in Patients Undergoing Hemodialysis

Background and Objectives: Fatigue is a common complaint among patients who undergo hemodialysis. Fatigue influences their somatic, mental, sentimental and cognitive states. This study aimed to determine the effect of progressive muscle relaxation technique on fatigue among patients treated with hemodialysis. Materials and Methods: In this clinical trial, 90 patients undergoing hemodialysis were recruited from two hemodialysis centers in Gonabad and Yazd and were randomly allocated into control (n=45) and trial (n=45) groups. The progressive muscle relaxation technique was presented to the trial group during three sessions. The patients were asked to make calm once a day for six weeks and at the end complete the relaxtion form. No trainings were provided for the control group patients. The intensity of fatigue was compared between the two groups. Data were collected using a questionnaire including demographic specifications, tools for assessing the severity of fatigue and self-reported checklists. Data was analyzed using the statistical methods in the SPSS. Results: The results showed no significant differences in the level of fatigue between the two groups before the intervention (p=0.12). There was significant difference in level of fatigue between the two groups after the intervention (p<0.001). Conclusion: Using the progressive muscle relaxation technique is recommended for patients of the hemodialysis ward

The effect of progressive muscle relaxation technique on blood pressure and dialysis adequacy in patients undergoing hemodialysis

Background and Aim: Dialysis inadequacy is a determinant of the patient’s life. Increased dialysis adequacy plays a significant role in improving awareness of dialysis patients. Blood pressure is also a significant factor in dialysis adequacy. This study aimed to evaluate the impact of Progressive Muscle Relaxation Technique on blood pressure and adequacy of dialysis in hemodialysis patients. Materials and Methods: This research was a clinical trial conducted in 2013. Hemodialysis patients from two hemodialysis centers in Gonabad (11 controls, 11 trials) and Yazd (34 controls, 34 trials) were chosen by the blocking method and allocated to two control (n=45) and trial (n=45) groups. Any trial received the Relaxation training by the investigator in 3 sessions and under similar circumstances. The patients performed the technique at home once a day for as long as 6 weeks. Then, the blood pressure and dialysis adequacy of the two groups were compared. The data was collected by a demographic questionnaire and a blood pressure checklist. KT/V formula was used to assess the adequacy of hemodialysis. Data was analyzed with SPSS software (version 14) using Independent T Test and Mann-Whitney U tests. Results: The results showed no significant difference in systolic and diastolic blood pressure between the two groups before intervention, but they were significantly different after the intervention (p<0.001). There was a significant difference in the mean difference of dialysis inadequacy before and after the intervention (p<0.001). After the intervention, dialysis adequacy increased in the intervention group (0.31±.0.12) but decreased in the control group (0.02±.0.1). Conclusion: Given the reduced blood pressure and increased adequacy in hemodialysis patients, this technique is recommended to be taught in hemodialysis ward

Combined Effect of Tape Drip Irrigation System Looping and Magnetic Water on Hydraulic Performance of Irrigation System and Water Use Efficiency in Maize

In this research, the effect of forming a loop layout by connecting the lateral ends in a tape irrigation system and magnetic water on yield and water use efficiency of maize cv. Maxima was investigated. The research was done as split plots on completely randomized blocks in three replications. Tube wires and an AC to DC converter were used to create a magnetic field. Maize water requirement was calculated using real-time meteorological parameters data of Zanjan synoptic station and FAO-56 method. Results showed loop connection compared with no-loop increased means of the system discharge by 13%, decreased coefficient of variation by 1.98%, and increased emission uniformity and Christiansen’s Uniformity coefficient by 2.2 and 1.5% (respectively). Magnetic water increased the means of the system discharge by 4.2% and decreased the coefficient of variation by 0.98% compared with no-magnetic water. Results of the measured plant traits showed that, compared with the conventional layout of the system, looping of the irrigation system increased means of the fresh plant weight, water use efficiency based on fresh plant weight, plant dry weight, and stem diameter by 27, 27, 32, and 13% respectively. Compared with non-magnetic water irrigation, magnetic water irrigation increased means of the fresh plant weight, water use efficiency based on fresh plant weight, plant dry weight, and leaf area by 9, 9.5, 1.4, and 17% respectively

Hospital Triage Standards: A Qualitative Study and Content Analysis based on Experts’ Experiences in Iran

Introduction: The lack of a fixed and clear protocol causes confusion for nurses resulting in care performance delay in the emergency room (ER). Given that the purpose of triage is to examine the patient upon arrival in ER for the rapid classification and prioritization of emergency patients in need of treatment, it seems that the development and implementation of hospital triage standards can greatly affect this purpose.&nbsp;Objective: The present study was conducted to review the experiences of experts in hospital triage in terms of determining the standards of hospital ER triage.&nbsp;Methods: This qualitative research was conducted through content analysis method based on Donabedian model. Participants include experts (Politician, Nurse Supervisor, Nurse, Midwife, Faculty of Nursing, Emergency Medicine Specialist) working in educational and private hospitals and single-specialized ERs. Data were collected through in-depth and semi-structured interviews lasting between 25-60 minutes. The main interview questions were: What are the structural standards of a good triage?&nbsp; What are the process standards for a good triage?&nbsp; What are the standards of a good triage? Data analyzed through Content Directed Analysis with Shannon and Hsieh approach.&nbsp;Results: Totally, 21 experts the mean age of 46.9±1.8 (ranged from 30 to 57) years and the mean work experience of 18.9± 8.21 years were participated, of whom 16 (76.2%) persons were male. From the analysis, we extracted 48 codes, 14 subcategories and 3 main categories of "structural standards", "process standards" and "outcome standards".&nbsp;Conclusions: Guidelines are needed so that the nurse in charge of triage can quickly and accurately undertake the important responsibility of patient triage. Additionally, having structure and process and outcome standards improves triage performance

As a general rule, the main purpose of using extensive monitoring, protection and control systems is to consider the stability and security of power systems. Therefore, in this paper, the above principles are considered and, with respect to the sample network, the relevant strategies have been implemented, and the simulation results point to improving security and stability in the power grid

Efficacy and Safety of the Irinotecan, Capecitabine, and Oxaliplatin (IOX) Regimen in Metastatic Gastric Cancer: A Single Arm Phase II Trial

Background: Gastric cancer is one of the most common malignancies worldwide with a high case mortality rate. In metastatic gastric cancer, a proper combination of chemotherapy could increase the survival rate. The goal of this study is to evaluate the efficacy and safety of the combination regimen of irinotecan, oxaliplatin, and Xeloda in metastatic gastric cancer. Methods: A total of 45 patients with metastatic gastric cancer and good performance status according to the Eastern Cooperative Oncology Group (score: 0-1) received the irinotecan, oxaliplatin, and Xeloda chemotherapy regimen. Demographic data, responses to treatment, and adverse effects were gathered for all cases. Overall survival and progression-free survival rates for patients were calculated using the Kaplan-Meier estimate. Results: Patients’ mean age was 58.3 ± 11.3 years (range: 24-81). There were 73.4% male patients and 26.6% female patients. Anorexia and weight loss were the most common symptoms. Overall response rate was 50%. The majority of toxicities were anemia, nausea and vomiting (grades 1 and 2), diarrhea (grades 1 and 2), neutropenia, alopecia, and hand and foot syndrome. The one-year progression-free survival rate was 31.5 ± 7.5%, whereas the twoyear progression-free survival rate was zero. The one-year overall survival rate was 34.91 ± 8.5%. Patients had a two-year overall survival rate of 7.7 ± 6.6%. Diffuse type cancer was linked to an inferior outcome. Conclusion: Regardless of our limited number of patients, this combination could be a suitable regimen for metastatic gastric cancer in terms of low toxicity, acceptable response rate, and survival results
