A new method for providing a model to analyze a kite wind turbine

The ultimate purpose of simulating kite wind turbine is to predict the kite movement and the power generated by its mechanism. To simulate because when the initial estimate of the intended values is found, we may have to manipulate the simulation to find the most efficient design for manufacturing our system and then predict the final power generated for our mechanism. Simulation for the system is based on two parts: Simulation of steady-state and dynamic model, which include differential equations. In this paper, we have presented a novel idea for a proper simulation of the system based on the two static and dynamic parts in order to numerical solution of the required amount and to calculate the output power.Keywords: Kite wind turbine; Simulation; Static model; Dynamic model;Winch; Torqu

Supply chain integration strategies in fast evolving industries

Purpose - The purpose of this paper is to define the "fast evolving industry" (FEI) and its supply chain management (SCM) challenges. The authors review and structure the literature regarding integration strategies and implementation methods to develop a strategic decision-making framework for SCM in the FEI. Design/methodology/approach - The authors conduct a review of SCM literature, including supply chain strategy, supply chain integration (SCI), agile and responsive supply chain and SCM for innovative and fast-changing industries. The authors develop a conceptual model and a decision-making framework and use four mini cases to provide support for the model and framework. Findings - The FEI, characterised by a high level of innovation and differentiation, short products/services lifecycle and high variety, is yet to be fully defined. Inherent uncertainty in FEI supply systems makes SCM in these industries a complex but strategic task for their managers. The framework and the model offered in this study, which employ a core competency concept and provide risk management strategies, offer a strategic tool for managers and scholars in the field to optimise their integration strategies and to operationalise integration decisions. Originality/value - Little research has been published on transferable and cross-industrial SCM in FEIs. This paper defines the FEI and its resource-related concerns and then offers a conceptual model and a strategic decision-making framework for SCI in FEIs

Self-burning: A common and tragic way of suicide in fars province, Iran

Self-burning is the most devastating burn injury. It is a common social and medical problem in Iran. In a longitudinal prospective study, from April 2003 to March 2006, all burn patients admitted to Ghotb-eddin burn Hospital were enrolled in this study. Suicide attempts by burning accounted for 283 (21.9%) of all burn patients admitted to the hospital. Most (68.2%) of self-burning patients were female. Self-burn patients had significantly large burned body surface area (64.8±29%). Suicidal burns occurred predominantly in the age group 15-24 years (44.6%). The mortality rate for suicidal burns was (60.4%). Fars is a province composed of many different tribes and cultural minorities whereby major decisions are made by forums of clergymen. It is important to involve those clergymen in burn prevention programs to achieve a meaningful reduction in Self-burning prevalence

Gender-related response of body systems in COVID-19 affects outcome

Severe acute respiratory syndrome (SARS)-like coronavirus (SARS-CoV-2) is the seventh member of the coronaviruses (CoVs) family that infects humans and causes coronavirus disease 2019 (COVID-19), which is currently a global pandemic. Widespread secretion of cytokines has been shown to occur early in severe cases of the disease and can be an effective factor in the rapid progression of the disease. Systemic inflammation indicates an advanced stage of acute disease, which is characterized by multiple organ failure and elevated key inflammatory markers. Studies have shown a gender difference between the incidence and mortality of COVID-19. In this review, we investigated the gender difference in the systemic effects of COVID-19 and found that this gender difference exists especially in the respiratory, cardiovascular, liver, gastrointestinal and kidney systems. Due to the worse outcome of COVID in males, the role of female sex hormones in causing these gender differences is noticeable. There can be a systemic and local effect of female sex hormones, especially estrogen and possibly progesterone, on various cells. Among the effects of these hormones is the regulation of localized angiotensin-converting enzyme 2 (ACE2) levels. ACE2 is the route of entry for SARS-CoV-2 virus into the cell. It is hoped that this review would address gender differences for better management of COVID-19 treatment

Interacting viscous ghost tachyon, K-essence and dilaton scalar field models of dark energy

We study the correspondence between the interacting viscous ghost dark energy model with the tachyon, K-essence and dilaton scalar field models in the framework of Einstein gravity. We consider a spatially non-flat FRW universe filled with interacting viscous ghost dark energy and dark matter. We reconstruct both the dynamics and potential of these scalar field models according to the evolutionary behavior of the interacting viscous ghost dark energy model, which can describe the accelerated expansion of the universe. Our numerical results show that the interaction and viscosity have opposite effects on the evolutionary properties of the ghost scalar filed models.Comment: 16 pages, 17 figure

Prediction of Breast Cancer Risk in Women over 35 Years Old Living in Villages of Zanjan: A Study Based on Gail Model

Background: Breast cancer is one of the most important malignancies in both developed and developing countries. Objectives: To reduce the burden of this disease, the prediction of individuals at risk and implementation of efficient preventive interventions can be effective. The present study was aimed at investigating five-year and lifetime risks of the breast cancer in a rural community in Zanjan province, Iran. Methods: A total of 435 subjects aged 35 years old were randomly selected using systematic randomization in a rural community in Zanjan. The participation rate was 92.4% (402 women). Data collection instrument was a questionnaire in which all associated variables of Gail model and demographic information were included. The data were analyzed using SPSS software version 18, and mean cancer risks were reported. Results: Family history of breast cancer and history of breast biopsy were found to be positive in 3.5% and 0.3% of participants, respectively. Out of all participants, 84.3% were under 60 years old and 13.2% were illiterate. Five-year and lifetime mean risks were fund to be 0.74% and 7.6%, respectively. About 2% of the participants had a higher cancer risk>1.66%. Conclusion: The findings demonstrated that based on the Gail model, the lifetime risk of the participants will be one out of 13 women. Given the lower estimations of Gail model in the prediction of breast cancer, we suggest general population interventions and high-risk strategies be implemented to decrease problems associated with the breast cancer in the future

New Mechanics of Traumatic Brain Injury

The prediction and prevention of traumatic brain injury is a very important aspect of preventive medical science. This paper proposes a new coupled loading-rate hypothesis for the traumatic brain injury (TBI), which states that the main cause of the TBI is an external Euclidean jolt, or SE(3)-jolt, an impulsive loading that strikes the head in several coupled degrees-of-freedom simultaneously. To show this, based on the previously defined covariant force law, we formulate the coupled Newton-Euler dynamics of brain's micro-motions within the cerebrospinal fluid and derive from it the coupled SE(3)-jolt dynamics. The SE(3)-jolt is a cause of the TBI in two forms of brain's rapid discontinuous deformations: translational dislocations and rotational disclinations. Brain's dislocations and disclinations, caused by the SE(3)-jolt, are described using the Cosserat multipolar viscoelastic continuum brain model. Keywords: Traumatic brain injuries, coupled loading-rate hypothesis, Euclidean jolt, coupled Newton-Euler dynamics, brain's dislocations and disclinationsComment: 18 pages, 1 figure, Late

Feasibility study of Tehran province water resources for fish production – Phase 1: Salehabad Qanat

This feasibility study carried out in response to request of Tehran Province Fisheries Management, in order to Qanat Salehabad water assessment for aquaculture relataed purposes in Tehran Municipality – Regions 19 & 20. During 6 monthes between May – October 2011 in 3 sampling stations by 3 replicates investigations executed. Physic-chemical, Heavy methals, organochloro-organophosphore pesticides and microbial nominated parameters analysed in reference to Iran national and international standards as well, resulted an overall assessment on quality and quantity of Qanat water for aquaculture purposes. Results expressed station 1 in all studied seasons can be develop for fisheries warmwater applications and in cold seasons (September-March) fisheries coldwater relevant activities can be consider. Stations No 2 & 3 known as infeasible for fisheries applications but would be recommend for agriculture rrigation. According to the results, possibility of developing live fish shopping centers (Cold – warmwatetr fishes) between station 1 and before crossing the Qanat flow and Behesht-e-Zahra freeway is considerable, indeed water rights could be negotiate between Tehran Municipality and Tehran province Fisheries Bureo. Also application of feasible anti microbial filters and other minimum limitation parameters control is necessary before leading Qanat water flow into proposed live fish shop. And suitable septic tank is recommended at the outlet of proposed fisheries units. Monitoring of nominated physic-chemical & microbial parameters during operation of fisheries unites highly recommended
