IoT-Enabled Operation of Multi Energy Hubs Considering Electric Vehicles and Demand Response

This paper introduces a novel Internet of Thing (IoT) enabled approach for optimizing the operation costs and enhancing the network reliability incorporating the uncertainty effects and energy management in multi-carrier Energy Hub (EH) and integrated energy systems (IES) with renewable resources, Combined Heat and Power (CHP) and Plug-In Hybrid Electric Vehicle (PHEV). In the proposed model, the optimization process of different carriers of Multi Energy Hubs (MEH) energy considers a price-based demand response (DR) program with MEH electrical and thermal demands. During the peak period, energy carrier prices are calculated at high tariffs, and other power hubs can help to reduce hub energy costs. The proposed model can handle the random behavior of renewable sources in a correlated environment and find optimal solution for turbines' communication in EHs. The simulation results show the high performance of the proposed model by considering the dependency between wind turbines in MEH structure, power exchange and heat among the EHs.© 2022 IEEE.

Techniques of Eyebrow Lifting: A Narrative Review

None of brow lift techniques are completely satisfactory because of their limited effectiveness, lack of longevity, and potential complications. The aim of this study was to provide a comprehensive review of the literature on the pros and cons of the most popular techniques in brow and forehead lift. Relevant original articles in the PubMed database (English language) were sought using the search terms “eyebrow lift”, “forehead lift”, ”periorbital rejuvenation”, ”eyebrow ptosis”, ”blepharoplasty and eyebrow change”, ”surgical eyebrow lift”, and ”non-surgical eyebrow lift”, No date limitation was considered. Titles and abstracts were scanned to include the most pertinent articles. Subsequently, full texts of included articles (111 articles) were skimmed and finally 56 references were selected for the review. A narrative synthesis of data was finally undertaken with particular attention to the indications, techniques, and common complications of the eyebrow lift procedures. Ten popular techniques including two nonsurgical methods (Botulinum toxin A and soft tissue fillers) were reviewed in this article. In general, non-surgical methods of forehead/brow lift are temporary, need less experience and correction would be easier should any complication occur. Surgical methods are divided into three categories: trans-blepharoplasty eyebrow lift, direct eyebrow lift, and trans-forehead eyebrow/forehead lift. Currently, the most popular method is the endoscopic forehead lift approach even though its longevity is limited. Direct brow-lift is particularly useful in patients with facial palsy and those who are more likely to be accepting of the scar (male gender, high forehead hair line)

Comparison of pulmonary arterial pressure in patients under chronic hemodialysis with and without arteriovenous fistula

BACKGROUND: Pulmonary arterial hypertension (PAH) is a progressive disorder and a newly-discovered disease in people with end stage renal disease (ESRD). In patients who are hemodialyzed through arteriovenous fistula (AVF), the incidence of pulmonary hypertension (PHT) is highly probable. Regarding the main role of the AVF in the pathogenesis of PAH and the fact that AVF is the main method of vascular access in patients undergoing dialysis, we decided to investigate pulmonary artery pressure (PAP) in patients under chronic hemodialysis.METHODS: This was a cross-sectional study. All patients with chronic hemodialysis were divided into two groups according to the status of the fistula. The number of cases examined included 100 patients and data were analyzed by SPSS software.RESULTS: The most common cause of ESRD was hypertension (HTN) followed by diabetes mellitus (DM), polycystic kidney disease (PKD), urologic disorders, DM and HTN, combined blood pressure (BP) and PKD, renal stones, and other items ultimately. The average creatinine level was 8.59 mg/dl. Therefore, the mean creatinine level of patients, although relative to mode and median, was in any case significantly higher than the mean, which was predictable according to the ESRD community studied. The mean phosphate level was 5.66 mg/dl, and the mean hemoglobin (Hb) was 11.56 g/dl. The mean parathyroid hormone (PTH) and PAP were 558.68 and 27.33 mmHg, respectively, and the mean of ejection fraction (EF) was 50.75%. There was a significant difference between the mean PAP in the two groups (P = 0.048), as it was higher in the AVF group.CONCLUSION: Results of this study showed that AVF and ESRD both were risk factors for high PAP and PHT

Environment effect on diversity in quality and quantity of essential oil of different wild populations of Kerman thyme

Thymus (thyme) is one of the most important genera with regard to the number of species within the family Lamiaceae. Kerman thyme (Thymus carmanicus Jalas) is an endemic Iranian species, intensively utilized because of its wide ranging medicinal and culinary properties. Aerial parts of T. carmanicus collected from various altitudes including 2000-2500, 2500-3000, and 3000- 3500 m above sea level in Zagros Mountains, Kerman province, South Iran. The yellow oil yields ranged between 0.80 to 1.10% (v/w) for populations collected from various elevations and for the populations collected from various regions ranged between 0.55-1.61% (v/w). GC-MS analyses revealed compounds, constituting 92.2-99.9% of total essential oils. The major constituents of essential oils were carvacrol (47.6-57.9%), thymol (8.3-19.0%), α-terpinene (7.3-7.9%) and p-cymene (4.4-7.6%), that monoterpenes, especially oxygenated monoterpenes was the main constituent group in essential oil from the aerial parts of T. carmanicus. The results of current study indicated that increasing elevation decreased thymol content in essential oils of the wild populations of T. carmanicus

A variable current-limit control scheme for a bi-directional converter used in ultracapacitor applications

In ultracapacitor applications, generally, a bi-directional converter is connected to a DC bus and is designed to compensate rapid load variations on the bus. During transient phases, overloaded DC bus can push the converter out of its operating limits. For providing the necessary power, converters should be put in parallel, while each converter is limited into its optimal operating range. In a boost converter, this operating limit can be related to the inductor current and UC voltage. In this study, a variable current-limit is proposed for inductor current which then determines the operating range of the boost converter. This method will provide stability of the converter during overload transients. An experimental setup consisting of a bidirectional converter, a controllable load/source, and an ultracapacitor is presented, to validate the proposed method. Several scenarii are applied to analyze the performance of the system in overloaded phases and theoretical and experimental results are presented

European Medicine and Physicians in Safavid Iran

Simultaneous with the establishment of the Safavid dynasty, due to the developments in the global and regional relations, the ground was prepared for the expansion of Iran and Europe relations. The main reasons for this were the propagation of Christianity, the presence of the Ottoman government as a common enemy of Iran and Europe, as well as commercial interests. These relations reached their peak during the reign of Shah Abbas I., encouraging various groups of Europeans, such as religious missionaries, businessmen, ambassadors, political delegations, tourists, etc. to come to Iran.Physicians were seen in all the mentioned groups, especially in religious missionaries. So, owing to their presence, medical knowledge of European was introduced to Iranians. The first acquaintance with medical profession of European was obtained at the same time as the presence of the Portuguese in the Persian Gulf. Syphilis, which was first entered Iran from Europe in the late ninth century and was called smallpox, led European medicine to entering Iran.The researchers of the present study, based on the reports related to the presence and activity of European physicians in Iran, travelogues and historical and research books, have used a descriptive-analytical method to examine the medical status and European physicians in Safavid Iran

The privatization effects on Iran insurance industry

Two methods of privatization through ownership transfer and privatization from below are more proper than other ones. The privatization program in Iran insurance industry is performed through privatization from below initiated from 2000 and proceeded in recent years by ownership transfer according to general policies of Iran Law. This paper shows how privatization from below is effective more than ownership privatization in competition extension in insurance industry and spread of its supporting businesses. This method have had more effects on insurance industry by extending insurance industry practices, leading to differentiation in insurance products, improving public firms' performance and extending insurance relevant businesses

Association between number and type of tooth loss on Oral Health Related Quality of life in 35-44 year olds in southeastern Iran.

Oral diseases can affect oral health related quality of life (OHRQol). The aim of the present study was to determine the association between the number and type of tooth loss on OHRQol in 35-44 year old individuals. This cross-sectional descriptive study conducted on 400, 35-44 year old people who visited Kerman clinics. Data were collected by using demographic and oral health behavior questionnaires, clinical examination (DMFT index) and the OHRQol questionnaire (OHIP-14). Data were analyzed in SPSS18, by t-test, X2 at 5% significance level. In the present study 206 (51.5%) were men, the mean age was 39.22±4.98 years and 52.0% had university education. The mean of DMFT and OHIP-14 scores were 13.3±4.5 and 18.6±8.3 (from 56) respectively. Men had lower OHRQol than women, but the difference was not significant. There was significant relation between educational level, oral health behavior, number and type of tooth loss and the OHRQol score. OHRQol was acceptable in this study and had a significant correlation with number and type of tooth loss. Further studies on other age groups is recommended. Keywords: oral health، quality of life, tooth loss, type of tooth loss, 35-44 years old، southeastern Iran

A Study of The Relationship Between The Components of The Five-Factor Model of Personality and The Occurrence of Occupational Accidents in Industry Workers

Accidents are among the most important problems of both the developed and the developing countries. Individual factors and personality traits are the primary causes of human errors and contribute to accidents. The present study aims to investigate the relationship between the components of the five-factor model of personality and the occurrence of occupational accidents in industrial workers. The independent T-test indicated that there is a meaningful relationship between the personality traits and accident proneness. In the two groups of industry workers injured in occupational accidents and industry workers without any occupational accidents, there is a significant relationship between personality traits, neuroticism (p=0.001), openness to experience (p=0.001), extraversion (p=0.024) and conscientiousness (p=0.021). Nonetheless, concerning the personality trait of agreeableness (p = 0.09), the group of workers with accidents did not differ significantly from the workers without any accidents. The results showed that there is a direct and significant relationship between accident proneness and the personality traits of neuroticism and openness to experience. Furthermore, there is a meaningful but inverse correlation between accident proneness and the personality traits of extraversion and conscientiousness, while there was no relationship between accident proneness and the personality trait of agreeableness
