Investigation of photo induced change of electro optical performance in a liquid crystal organic field effect transistor (LC OFET)

This study aimed to improve the electrical characteristics of poly(3 hexylthiophene) (P3HT) and liquid crystal organic field effect transistors (LC OFETs) under UV illumination. Consequently, a novel LC OFET was fabricated using a nematic liquid crystal (E63) and a P3HT mixture in an OFET cell. Cell thickness was determined through field emission scanning electron microscopy. For assessment of the electrical characteristics, the LC OFET device was exposed to various UV light intensities in total darkness for the purpose of obtaining the output and transfer current voltage. The capacitance frequency plot of the capacitor cell was then measured to determine the main parameters including the threshold voltage (VTh) field effect mobility (mFET) and current on/off ratio (Ion/off) of the device. Thus, the full characterisation and UV light response of the electronic parameters were determined for this new class of transistors. Results showed that the new LC OFET exhibited good performance in the form of low VTh, high mFET, and high Ion/off.
Effect of additives on formation and decomposition kinetics of methane clathrate hydrates: Application in energy storage and transportation

Methane gas storage and transportation via clathrate hydrates is proposed to be a potential solution for large scale energy storage. In this work, we study the formation and decomposition kinetics of methane hydrates (MH) in a laboratory scale unstirred crystallizer. The present investigation demonstrates comparative studies of hydrate formation and dissociation kinetics in the presence of tetrahydrofuran (55.6 and 27.8 mmol/mol, 5.56 and 2.78 mol THF) and sodium dodecyl sulphate (1 mg/g, 0.1 wt% SDS) Moreover, the storage capacity and hydrate formation kinetics in both the systems are discussed. In a recent work, enhanced methane hydrate growth in the presence of THF at close to atmospheric conditions was demonstrated. The emphasis of the current work is to study the stability of hydrates to understand dissociation kinetics by measuring the rate of hydrate decomposition at different temperatures. Hydrate stability measurements were performed at 8, 3, 2, 10, and 20 degC to study the decomposition rates of MH and self preservation in presence of the two additives THF and SDS.
Filtration model for the detection of malicious traffic in large scale networks
Venue: Comput. Commun.

This study proposes a capable, scalable, and reliable edge to edge model for filtering malicious traffic through real time monitoring of the impact of user behavior on quality of service (QoS) regulations. The model investigates user traffic, including that injected through distributed gateways and that destined to gateways that are experiencing actual attacks. Misbehaving traffic filtration is triggered only when the network is congested, at which point burst gateways generate an explicit congestion notification (ECN) to misbehaving users. To investigate the behavior of misbehaving user traffic, packet delay variation (PDV) ratios are actively estimated and packet transfer rates are passively measured at a unit time. Users who exceed the PDV bit rates specified in their service level agreements (SLAs) are filtered as suspicious users. In addition, suspicious users who exceed the SLA bandwidth bit rates are filtered as network intruders. Simulation results demonstrate that the proposed model efficiently filters network traffic and precisely detects malicious traffic.

The Mediating Effect of Safety Culture on Safety Communication and Human Factor Accident at the Workplace

Rapid development in industrialization and global economy has contributed to the increased number of workplace injuries and accidents. Nowadays, with the advancement and the reliability of technology, accidents caused by equipment and machinery failures seem to be on decline. However, human element tends to feature as a significant contributor to workplace accidents statistical reports and evidence indicate that around 80 to 90 percent of work related accidents can be attributed to human factors. Meanwhile, effective safety communication is believed to play a vital role in human factor accidents at the workplace. Effective communication among the workers and leaders is believed to help in the attenuating the risk of human factor accidents. Against this background, this research examines 394 sets of questionnaires with 89.14% response rate from respondents of manufacturing companies in Negeri Sembilan, Malaysia. Based on the results, the interaction between safety communication and human factor accident is found to be significant. In addition, this study investigates the mediating effect of safety culture between safety communication and human factor accident. The results show that safety culture significantly mediates by the relation of safety communication and human factor accident.
Monte Carlo Confidence Intervals for Complex Functions of Indirect Effects

One challenge in mediation analysis is to generate a confidence interval (CI) with high coverage and power that maintains a nominal significance level for any well defined function of indirect and direct effects in the general context of structural equation modeling (SEM) This study discusses a proposed Monte Carlo extension that finds the CIs for any well defined function of the coefficients of SEM such as the product of k coefficients and the ratio of the contrasts of indirect effects, using the Monte Carlo method. Finally, we conduct a small scale simulation study to compare CIs produced by the Monte Carlo, nonparametric bootstrap, and asymptotic delta methods. Based on our simulation study, we recommend researchers use the Monte Carlo method to test a complex function of indirect effects.
Body weight and risk of molecular breast cancer subtypes among postmenopausal Mediterranean women.
Venue: Current research in translational medicine

Breast cancer (BC) is the most common malignant tumor in women, obesity is associated with increased BC incidence and mortality and high levels of circulating insulin may negatively impact on cancer incidence. In the present study, we investigated whether the strength of several anthropometric and metabolic parameters varies between BC molecular subtypes. Eligible cases were 991 non metastatic BC patients recruited between January 2009 and December 2013. Anthropometric, clinical and immunohistochemical features were measured. Multivariate logistic regression models were built to assess HER2 positive BC risk, comparing (a) triple positive (TP) with luminal A, luminal B and triple negative (TN) and (b) HER2 enriched group with luminal A, luminal B and TN. We stratified patients in pre and post menopause: significant differences emerged for luminal A in relation to age: they were more likely to be older compared to other groups. Among postmenopausal patients, the adjusted multivariate analysis showed that high BMI and high waist circumference were inversely correlated to TP subtype when compared to luminal B (OR=0.48 and OR=0.49, respectively) Conversely, HOMA IR was a risk factor for TP when compared to luminal A and TN (OR=2.47 and OR=3.15, respectively) Our findings suggest a potential role of higher abdominal fat in the development of specific BC molecular subtypes in postmenopausal women. Moreover, they support a potential role of insulin resistance in the development of HER2 positive BC, although this role appears to be stronger when hormone receptors are co expressed, suggesting a difference in the etiology of these two BC subtypes.

North eastern India has been known for its rich biological diversity. For this study, seven medicinal plants such as Bryophyllum pinnatum, Ipomea aquatica, Oldenlandia corymbosa, Ricinus communis, Terminalia bellerica, Tinospora cordifolia, and Xanthium strumarium, were selected. The aim of the present study was to investigate the presence of phytochemicals and to determine the total phenolic and flavonoid contents of the selected medicinal plants. Soxhlet apparatus was used for the organic solvent extraction. Solvents used were water, methanol, ethanol, and acetone. Total phenolic contents of the aqueous extracts of the plants were determined by the Folin Ciocalteus reagent method whereas total flavonoid contents of the aqueous extracts were determined by the Aluminium Chloride method. Proteins, carbohydrates, phenols, tannins, flavonoids, saponins, were detected in all of the plants tested. Total phenolic contents obtained were 18.4mg/gm, 18.8mg/gm, 11.6mg/gm, 29.2mg/gm, 29.6mg/gm, 40.8mg/gm, 12.8mg/gm, 71.6mg/gm of the extract and total flavonoid contents obtained were 8.4mg/gm, 37.6mg/gm, 4.4mg/gm, 6mg/gm, 42.8mg/gm, 18mg/gm, 6mg/gm, 28.8mg/gm of the extract for the plants Bryophyllum pinnatum (Leaves) Ipomea aquatica (Leaves) Oldenlandia corymbosa (Whole plant) Ricinus communis (Roots) Terminalia bellerica (Leaves) Tinospora cordifolia (Leaves) Tinospora cordifolia (Stem) and Xanthium strumarium (Leaves) respectively. Our findings provided evidence that crude aqueous and organic solvent extracts of these tested plants contain medicinally important bioactive compounds and it justifies their use in the traditional medicines for the treatment of different diseases.
A Friendly Relationship between Endophytic Fungi and Medicinal Plants: A Systematic Review
Venue: Front. Microbiol.

Endophytic fungi or endophytes exist widely inside the healthy tissues of living plants, and are important components of plant micro ecosystems. Over the long period of evolution, some co existing endophytes and their host plants have established a special relationship with one and another, which can significantly influence the formation of metabolic products in plants, then affect quality and quantity of crude drugs derived from medicinal plants. This paper will focus on the increasing knowledge of relationships between endophytic fungi and medicinal plants through reviewing of published research data obtained from the last 30 years. The analytical results indicate that the distribution and population structure of endophytes can be considerably affected by factors, such as the genetic background, age, and environmental conditions of their hosts. On the other hand, the endophytic fungi can also confer profound impacts on their host plants by enhancing their growth, increasing their fitness, strengthening their tolerances to abiotic and biotic stresses, and promoting their accumulation of secondary metabolites. All the changes are very important for the production of bioactive components in their hosts. Hence, it is essential to understand such relationships between endophytic fungi and their host medicinal plants. Such knowledge can be well exploited and applied for the production of better and more drugs from medicinal plants.
Structure and electronic properties of palladium chains supported by NiAl(1 1 0) A first principles study

In this work, the geometry, stability and electronic structures of atomic palladium chains supported on the NiAl(1 1 0) surface have been investigated by using the first principles calculations. Palladium monomer strongly adsorbed at Ni Ni and Al Al bridge sites bonding with the two most neighboring Ni atoms. There is competitive mechanism between interactions of Pd Pd and interactions between Pd and NiAl substrate for Pd ad chains. We also observe the interactions of resonance states give rises to a band of resonance states, which is mainly related to the overlap of 5sp orbital of adjacent Pd atoms. Finally, we demonstrated that the atomic spacing in Pd ad chains and adsorption sites had significant influences to the bandwidth of resonance band. These results may have potential applications in the fields of nanoelectronics and nanoscale catalysts.
From 'silent borrowing' to the international argument legitimating Swedish educational policy from 1945 to the present day

The article analyses how education policy making was legitimated in Sweden in the time period 1945 2014, focussing particularly on international points of reference and using reports of government committees 'Statens offentliga utredningar' or SOU) as an indicator for the policy making discourse. The article detects a shift in how policy agendas were justified that ca. 2007. Before the shift, international reference points were hardly ever used as an argument for reform in policy making, despite the fact that Sweden in many ways participated in the international education policy making mainstream. This changed around the year 2007, when the 'international argument' became prominent in the education policy making discourse as a legitimatory device and justification for change. The article argues that this shift is connected to declining Swedish PISA results and a changed perception of these results in Sweden.
Response of the soil microbial community composition and biomass to a short term Spartina alterniflora invasion in a coastal wetland of eastern China
Venue: Plant and Soil

AimsPlant invasion has been reported to alter ecosystem carbon (C) and nitrogen (N) cycling processes and pools. The mechanisms involved in how plant invasion affects the soil microbial community the primary mediator of soil C and N cycling remain poorly understood. The objective of this study was therefore to evaluate the effect of plant invasion on the soil microbial community in a coastal wetland of eastern China.MethodsWe investigated the impact of an exotic C4 perennial grass, Spartina alterniflora, on the soil microbial community structure based on phospholipid fatty acids (PLFAs) analysis and chloroform fumigation extraction by comparing it to that of bare flat and native C3 plants Suaeda salsa and Phragmites australis communities.ResultsSpartina alterniflora invasion significantly increased soil microbial biomass C and the total and various types of PLFAs compared with bare flat, Suaeda salsa and Phragmites australis communities. Increased concentrations of soil moisture, electrical conductivity, water soluble organic carbon (WSOC) and total, labile and recalcitrant soil organic C and N, and decreased soil pH in Spartina alterniflora community explained 65.9 of the total variability in the PLFAs. WSOC and soil labile organic N were strongly correlated with PLFAs, whereas soil pH was negatively related to PLFAs.ConclusionsA 10 year Spartina alterniflora invasion significantly altered soil microbial biomass and community structure by increasing available substrate. The changes in soil microbial biomass and community structure may in turn enhance soil C and N sequestration in a coastal wetland of eastern China.
Spartina alterniflora invasion alters soil microbial community composition and microbial respiration following invasion chronosequence in a coastal wetland of China
Venue: Scientific reports

The role of exotic plants in regulating soil microbial community structure and activity following invasion chronosequence remains unclear. We investigated soil microbial community structure and microbial respiration following Spartina alterniflora invasion in a chronosequence of 6 10 17 and 20 year old by comparing with bare flat in a coastal wetland of China. S. alterniflora invasion significantly increased soil moisture and salinity, the concentrations of soil water soluble organic carbon and microbial biomass carbon (MBC) the quantities of total and various types of phospholipid fatty acids (PLFAs) the fungal:bacterial PLFAs ratio and cumulative microbial respiration compared with bare flat. The highest MBC, gram negative bacterial and saturated straight chain PLFAs were found in 10 year old S. alterniflora soil, while the greatest total PLFAs, bacterial and gram positive bacterial PLFAs were found in 10 and 17 year old S. alterniflora soils. The monounsaturated:branched PLFAs ratio declined, and cumulative microbial respiration on a per unit PLFAs increased following S. alterniflora invasion in the chronosequence. Our results suggest that S. alterniflora invasion significantly increased the biomass of soil various microbial groups and microbial respiration compared to bare flat soil by increasing soil available substrate, and modifying soil physiochemical properties. Soil microbial community reached the most enriched condition in the 10 year old S. alterniflora community.
The nonconforming virtual element method for plate bending problems

We develop the nonconforming virtual element method for linear plate bending problems. A class of nonconforming virtual elements is constructed, which is C0 continuous. Like the classical nonconforming plate elements, it relaxes the continuity requirement for the function space to some extent. Further, the virtual element is constructed for any order of accuracy and adapts to complicate element geometries. We present a general framework on the error analysis for the nonconforming virtual element method, highlighting the main difference with the conforming one.
NO reduction by CO over TiO2 G Al2O3 supported In/Ag catalyst under lean burn conditions

Al 2 O 3 supported In/Ag catalysts were prepared by impregnation method, and investigated for NO reduction with CO as the reducing agent under lean burn conditions. The microscopic structure and surface properties of the catalysts were studied by N 2 adsorption desorption, X ray diffraction, transmission electron microscopy, X ray photoelectron spectroscopy, ultraviolet visible spectroscopy, H 2 temperature programmed reduction and Fourier transform infrared spectroscopy. TiO 2 /G Al 2 O 3 supported In/Ag is a good catalyst for the reduction of NO to N 2 It displayed high dispersion, large amounts of surface active components and high NO adsorption capacity, which gave good catalytic performance and stability for the reduction of NO with CO under lean burn conditions. The silver species stabilized and improved the dispersion of the indium species. The introduction of TiO 2 into the G Al 2 O 3 support promoted NO adsorption and improved the dispersion of the indium species and silver species.
Brand Influence in Business to Business (B2B) Markets Understanding the Buying Criteria of Different Organizations

The brands make identification of products, services, and businesses convenient, easy, and more acceptable for the buyers. Besides, the brands help to differentiate them from competitors' offerings. The brands also communicate improved value and benefits to the business buyers. And brands also act as a measure of guarantee for quality, performance, and the source; and thus reduce the risk and complexities in buying decisions. The objective of the study was to have a deeper understanding of the various evaluative criteria used in different B2B purchase decisions, and to what extent a brand influences them and how beneficial are those decisions for the buying organizations. The study was focused around the value and importance of branding, the preference towards branded products, and the effect of factors like price, risks involved, information availability, customer support/ after sales services, and value addition on purchase decisions in organizations. The study was conducted with 110 respondents from four different industry categories purchasing and using namely, garment manufacturing machinery, photocopiers, photographic equipment, and medical diagnostic equipments with the help of a questionnaire and interview. The study revealed that more or less, industrial and organizational buyers, though very price conscious, prefer branded products because it gives a mental satisfaction that they are buying a quality product and associated services from a reliable and known source. The companies supplying branded products provide quick backup service and support, and they are more preferred because it assures quick response and solution of any bottleneck and issue with the final end product/ service produced in the buying organization.
