Constant-Stress Accelerated Degradation Life Test of an Organic Light-Emitting Diode Display under Violet Light

Author(s): François-Xavier Fortier, Sylvain G. Cloutier

ABSTRACT
The lifetime of commercial OLED display devices increases, so does the need for an accelerated lifetime testing method. The present work proposes a simple and accurate blackbox testing approach for commercial PMOLED display lifetime assessment using violet light-induced accelerated aging. Maximum likelihood estimations using lognormal distributions are performed based on datasets acquired from samples exposed to six different degrees of violet irradiance Continue reading

What Supported the Growth of China’s Air Transport Industry from 1955 to 2011?

Author(s): Xingwu Zheng, Yi Zhang, Wei Lu

ABSTRACT
China’s civil aviation industry experienced an average annual growth rate of over 16% for traffic turnover during 1955-2011. It is important to identify the role of capital and labor inputs as well as total factor productivity (TFP) in China’s civil aviation industry during this period of time. First, the inputs of capital stock and labor as well as the output of traffic turnover in China’s air transport industry are measured. Next, the constrained E-G two-stage estimation of the CD production function Continue reading

Nickel Antimony Sulphide Thin Films for Solar Cell Application: Study of Optical Constants

Author(s) : Saima Mushtaq , Bushra Ismai , Muhammad Raheel, Aurang Zeb

ABSTRACT
NS_2016020314151476Chemical bath deposition technique has been used to deposit Ni-doped Sb2S3 thin films onto glass substrate. Doping was carried out by adding 1, 3 and 5 wt% of Ni. Bath temperature was kept as 10℃ and films were annealed at 250 ℃ under vacuum. Polycrystalline nature of films with an orthorhombic phase was analyzed by X-ray diffraction technique. Scanning electron microscopy was used for morphological study which shows that grains are spherical. Optical measurements using transmittance data indicated that films have a direct band gap of 1.00 – 2.60 eV with an absorption coefficient of ~104 cm – 1 in visible range. The average value of electrical conductivity was calculated as 1.66, 1.11 and Continue reading

Radiation Induced Bystander Effect: From in Vitro Studies to Clinical Application

Author(s): Maria Widel

ABSTRACT
In the past 20 years, the classic paradigm in radiobiology recognizing DNA as the main target for the action of radiation has changed. The new paradigm assumes that both targeted and non-targeted effects of radiation determine the final outcome of irradiation. Radiotherapy is one of the main modality treatments of neoplastic diseases with intent to cure, or sometimes to palliate only, thus radiation-induced non-targeted effect, commonly referred to as the radiation-induced bystander effect (RIBE) may have a share in cancer treatment. RIBE is mediated by molecular signaling Continue reading

Design of Smart Home System Based on ZigBee Technology and R&D for Application

Author(s): Lin Gao, Zhixin Wang, Jianlong Zhou, Chao Zhang

ABSTRACT
In this paper, a smart home system based on ZigBee technology is designed. The system includes home network, home server and mobile terminal. The program is highly scalable and cost-effective. This paper developed the home server-side application based on MFC technology and the mobile terminal application. The mobile client can remotely control home devices and query the running state, electric energy information and historical data of home devices. At the same time, the home Continue reading

Addressing Foreign Language Learning Anxiety with Facebook

Author(s):Serge Gabarre, Cécile Gabarre, Rosseni Din, Parilah Shah, Aidah Abdul Karim

ABSTRACT
Learning a foreign language can be a daunting task which challenges students in several ways. Although students more readily identify anxiety as linked to speaking, all other language skills have been linked to Krashen’s affective filters. The present study sought to address these filters, with an emphasis on anxiety, by incorporating Facebook on mobile phones in the language classroom. A grounded action research method was adopted for the implementation as it enabled the researchers to alter their Continue reading

The Use of Umbilical Stem Cells

Author(s): Peter Cassar, Renald Blundell

ABSTRACT
The use of umbilical stem cells in tissue engineering is gaining in popularity. Some of the various uses of these umbilical stem cells are highlighted in this review, focusing mainly on their cartilage, bone and neuronal differentiating abilities. The review will also shed light on the application of these abilities in human clinical trials to repair, protect and treat diseases, e.g. neurodegenerative diseases such as Alzheimer’s and cerebral palsy. Continue reading

Does Exposure to Noise Lead to Decreased Regulatory Abilities, and Increased Aggression?

Author(s): Farzaneh Pahlavan, Melana Arouss

ABSTRACT
Recent advances in the study of affective-cognitive regulation of aggressive behavior suggest positive correlations between poor executive capacities (ECF) and negative reactivity. If the global assumption is correct what are the likely implications of predicted relation? The central issue in present research is to verify this assumption and examine how situational characteristics can alter executive performance in adults experiencing Civil War (Syrians students living in their country or in a host country) and adults experiencing peaceful life (French students) to explore some of the Continue reading

Sclerotia Formation and Toxin Production in Large Sclerotial Aspergillus flavus Isolates from Kenya

Author(s): S. A. Okoth, B. Nyongesa, V. Joutsjoki, H. Korhonen, V. Ayugi, E. K. Kang’ethe

ABSTRACT
We studied the relationship between sclerotia formation and aflatoxin production by Aspergillusflavus strains isolated from maize kernels from Nandi County. Isolates recovered from maize kernels were tested for their ability to form sclerotia on different growth media. PCR analysis was done on the isolates to detect 2 structural genes, aflD and aflQ, involved in aflatoxin biosynthesis pathway. Continue reading

Application of High-Frequency Gravitational Waves to the Cataclysmic Event of Our First Encounter with Intelligent Extraterrestrial Beings

Author(s): Robert M. L. Baker, Bonnie Sue Baker

ABSTRACT

Brain-to-brain direct communication (Power, [85] and Grey [86]).
Brain-to-brain direct communication (Power, [85] and Grey [86]).
Three advances are proposed as a pathway to the cataclysmic event of our first encounter with intelligent extraterrestrial beings. First, discovery of very large numbers of extraterrestrial planets, “exoplanets” (possibly as many as1023 in our Universe); second, introduction of electronic components into the human body evolving into a cybernetic and biological “cyborg,” a model for an extraterrestrial being Cyborgs might allow advanced civilizations to endure hundreds of thousands of years. Continue reading
