Printed organic TFTs on flexible substrate for complementary circuits

Organic Thin film Transistors (OTFT) have been widely investigated in these last years as potential candidate for the development of low cost, flexible and lightweight active-matrix backplanes for display applications. Indeed the organic semiconductors provide both promising electrical performances tunable by chemistry and the ability to be processed at low temperature with innovative printing technics on various large scale substrates. Thanks to the recent developments on both n-type and p-type solution-processed organic semiconductors, we have developed a printable organic complementary technology compatible with flexible PEN substrates. By combining state of the art materials exhibiting mobility in the range of 1 cm 2 /V.s and silicon inspired compact modeling and simulation approach, we were able to design and fabricate circuit's building blocks that provide the switching, digital and analog functions required for the fabrication of printed systems on foil

The relationship between religious orientation and spiritual experience, self-esteem of pregnant mother’s city of Susa

Faith a significant impact on the human soul because confidence and her strength, patience and tolerance have increased the hardships of life and a sense of security and peace in his soul established and within comfort remember creates. Method of present study is descriptive and correlational. The study population included all of pregnant mother’s city of Susa in 2015 that of this number (50) were selected by simple random sampling. The tool measuring data include: religious orientation questionnaire (Allport), scale of Spiritual Experience (DSES) and self-esteem scale (Rosenberg). To analyze the data using statistical software SPSS and correlation coefficient and regression analysis were used. Pearson correlation coefficients showed that the spiritual experience and there is no significant relationship between self-esteem and also found that between self-esteem and there is a significant negative relationship between the religious orientation. Given the importance of the role of religion, mental health and physical recommended mothers in the promotion and fostering spirituality among of pregnant mothers more attention. © Medwell Journals, 2016

Organic and amorphous-metal-oxide flexible analogue electronics

Recent years have witnessed significant research efforts in flexible organic and amorphous-metal-oxide analogue electronics, in view of its formidable potential for applications such as smart sensor systems. This Element provides a comprehensive overview of this growing research area. After discussing the properties of organic and amorphous-metal-oxide technologies relevant to analogue circuits, this Element focuses on their application to two key circuit blocks: amplifiers and analogue-to-digital converters. The Element thus provides a fresh look at the evolution and immediate opportunities of the field, and identifies the remaining challenges for these technologies to become the platform of choice for flexible analogue electronics

An Analysis of Hydatid Cyst Surgeries in Patients Referred To Hospitals in Khorram-Abad, Lorestan during 2002-06

Background: Echinococcosis or hydatid cyst (HC) is considered as one of the major parasitic infections in Iran that causes many health problems and economic losses in communities. The aim of this study was to determine the prevalence of HC in patients referred to surgery wards of three hospitals in Khorram-Abad, the center of Lorestan province in South-West of Iran from 2002 - 2006."nMethods: Totally, 64513 medical records of patients referred to surgery wards of Shohadaye Ashayer, Tohid and Taamine Ejtemaee hospitals in Khorram-Abad Lorestan were studied. These patients had gone under surgical operations for different reasons. Among these medical records, 43.7% belonged to Shohadaye Ashayer, 8.2% to Tohid and 18.1% to Taamine ejte¬maee hospitals."nResults: Cysts were found in liver and lung in 61.5% and 20.5% of cases, respectively. In addition, cysts were found in brain, muscle, kidney eye and peritonea in the remaining 18% of cases. "nConclusion: A very low level of knowledge about hydatid disease was found in the community. The mean age of the pa-tients was 40.2 years and the highest rate of infection with HC was observed in women. Further studies are required to find the etiologic factors of H.C in Khorram-Abad Lorestan-Iran

Screening of congenital CMV infection in saliva of neonates by PCR: Report of a pilot screening study in Iran

Background: Cytomegalovirus (CMV) is a leading cause of congenital infection in neonates. Most infants with congenital CMV infection are asymptomatic at birth and not diagnosed on routine clinical examination. To identify these at-risk infants early in life, polymerase chain reaction (PCR) assays are done to screen large populations of newborn infants. Objective: We carried out a pilot study to estimate the prevalence of CMV in saliva from newborns by DNA PCR assay. Methods: This study was performed from January 2012 to March 2012 at a maternity hospital in the south of Tehran. All newborns aged between 1 to 14 days born at this hospital were enrolled. Saliva specimens from newborns were collected by swabbing the inside of the baby's mouth and stored at -70°C until PCR processing for virus detection. Results: Six-hundred and twenty infants between 1 to 14 days of age were enrolled during the study period of two months. The PCR assay was positive for CMV in 2 newborns 0.3%. Both of these infants were asymptomatic for congenital CMV at birth and also when followed up at three months and six months of age. Conclusions: Our findings reveal that because of a low yield of positive results, screening for congenital CMV infection would not be cost-effective in Iranian neonates

A 13.56MHz RFID tag with active envelope detection in an organic complementary TFT technology

In the last several years, organic electronics have gained increasing consideration as a cost-effective alternative to silicon, especially in RFID applications. An inductive-coupled organic RFID operating at 13.56MHz was demonstrated on foil using p-type organic technologies [1]. A complementary organic technology was used for a 13.56MHz transponder in [2]. Recently, a complementary hybrid organic/metal-oxide process was exploited to demonstrate bidirectional communication in an HF RFID [3]. It adopts passive envelope detection using traditional diode-based schemes with OOK modulation. However, OOK modulation usually reduces sensitivity and reading range. In this work, a complementary organic TFT (C-OTFT) technology [4] is used for the first time to implement a 13.56MHz RX front-end, which exploits an active detection scheme and is able to demodulate ASK PWM-coded signals with modulation depth (h) as low as 25%
