A High Efficiency Chlorophyll Sensitized Solar Cell with Quasi Solid PVA Based Electrolyte

The objective of this work is to investigate the performance of chlorophyll sensitized solar cells (CSSCs) with gel electrolyte based on polyvinyl alcohol (PVA) with single iodide salt (potassium iodide (KI)) and double salt (KI and tetrapropylammonium iodide (TPAI)). Chlorophyll was extracted from the bryophyte Hyophila involuta. The CSSC with electrolyte containing only KI salt produced a short circuit current density () of 4.59 mA cm−2, open circuit voltage () of 0.61 V, fill factor (FF) of 0.64, and efficiency () of 1.77%. However, the CSSC with double salt electrolyte exhibited of 5.96 mA cm−2, of 0.58 V, fill factor FF of 0.58, and of 2.00%. Since CSSC with double salt electrolyte showed better efficiency, other cells fabricated will use the double salt electrolyte. On addition of 0.7 M tetrabutyl pyridine (TBP) to the double salt electrolyte, the cell’s efficiency increased to 2.17%, mA cm−2, V, and FF = 0.73. With 5 mM chenodeoxycholic acid (CDCA) added to the chlorophyll, the light to electricity efficiency increased to 2.62% with of 8.44 mA cm−2, of 0.54 V, and FF of 0.58.
High-frequency quantum admittance and noise measurement with an on-chip resonant circuit

By coupling a quantum detector, a superconductor-insulator-superconductor junction, to a Josephson junction \textit{via} a resonant circuit we probe the high frequency properties, namely the ac complex admittance and the current fluctuations of the Josephson junction at the resonant frequencies. The admittance components show frequency dependent singularities related to the superconducting density of state while the noise exhibits a strong frequency dependence, consistent with theoretical predictions. The circuit also allows to probe separately the emission and absorption noise in the quantum regime of the superconducting resonant circuit at equilibrium. At low temperature the resonant circuit exhibits only absorption noise related to zero point fluctuations, whereas at higher temperature emission noise is also present.
Effect of Psycho-physical Stress on the Preference of Non- Athletic Youths for Intermittent or Continuous Bench- Stepping

This study was conducted to determine the preference of untrained, youths for Intermittent Stepping (IS) or Continuous Stepping (CS) test of cardio - respiratory fitness, based on their perceived exertion. Sixty male non-athletes who were 23.8+4.5 years old, weighed 62.58kg and were 172.6+cm tall, went through 6 minutes each of IS and CS on a 40cm high bench at 15 steps per minute. The IS protocol had one minute rest interspersed between it after 3 minutes. Systolic Blood Pressure (SBP), Diastolic Blood Pressure (DBP), heart rate (HR) and pulse pressure (PP) were obtained pre and post test. They rated their perceived exertion on a standard 15 point perceived exertion scale and later reported their preferred protocol. 70% preferred IS while 30% preferred CS. Significant rise in SBP, DBP, HR was induced by both IS (P .05). The CS protocol (work intensity ≥13) is therefore recommended for preferential use in testing military and paramilitary recruits while, IS protocol (work intensity ≤12) is recommended for low fit fresh entrants in recreational and other sports and in clinical settings for fitness testing and exercise therapy in low technology environments
The Rys quadrature revisited: A novel formulation for the efficient computation of electron repulsion integrals over Gaussian functions

A novel formulation of the Rys quadrature algorithm for the calculation of the electron repulsion integrals over Gaussian basis functions is presented. The new algorithm is specifically designed for high contractions. As for the original Rys quadrature algorithm, the new algorithm is very efficient for high angular momentum functions. In addition it is also equally efficient for low angular momentum functions. The new algorithm takes unique advantage of (1) the numerical Rys quadrature methodology in (2) dealing with charge distributions a la McMurchie–Davidson and in (3) scaling integral blocks as a means of transferring angular momentum a la Gill–Head–Gordon–Pople. An analysis of the algorithm suggests very favorable floating-point operation counts.
An improved encapsulation protocol for regrowth and conservation of four ornamental species

The encapsulation technology, initially developed for clonal propagation through the production of synthetic seeds with somatic embryos, is currently proposed for use with non-embryogenic explants, such as buds and nodal segments (unipolar propagules). In the present study, the encapsulation procedure and its effect on shoot regeneration were evaluated. Apical buds isolated from shoot cultures of four ornamental species ( Photinia × fraseri Dress., Polygala myrtifolia L., Metrosideros excelsa Soland. ex Gaertn., and Rosa ) were encapsulated in 3% sodium alginate. Effects of complexation time, sucrose concentration, and storage temperature on the regrowth ability of propagules were assessed. With the appropriate combination of sucrose concentration and polymerization time, the encapsulated explants proved to have a better regrowth (80–100%) after sowing than the naked ones. In addition, medium-term storage of Metrosideros encapsulated explants promoted a high level of regrowth (74%) after 4 months in the dark at 10°C; while polygala beads were preserved up to 8 months regardless of storage temperatures. Potential current applications of encapsulation technology and the future use of beads in vivo conditions are also discussed.
Feedforward and Feedback Control of Dynamic Systems

Abstract Recently the control methods based on disturbance rejection have largely renewed our understanding of automatic control, especially the role of feedforward control. With the renewed understanding, this work presents a feedforward and feedback approach for control of general dynamic systems under a state tracking framework. This is realized by introducing a fictitious system model and employing a proper state and disturbance estimator. The resultant control scheme embodies a close cooperation between feedforward and feedback controls: Feedforward control rejects the general disturbance and embeds a reference state trajectory, whilst feedback control cancels the fictitious dynamics and enforces desired tracking error dynamics. A notable advantage of the approach is that control designs of linear and nonlinear systems can follow a common routine and the closed-loop stability is guaranteed under standard conditions.
Identification of AFLP markers associated with flowering time and ornamental traits in Chrysanthemum

Flowering period and longevity play important roles in determining the quality of commercial flowers. Marker-trait associations for eight flowering and 12 ornamental traits have been studied using a GLM and MLM analysis with a set of 2099 AFLP polymorphic markers in Chrysanthemum. The GLM model identified 453 markers for phenotypic traits whereas the MLM association analysis model revealed a total of 197 significant marker-trait associations for the phenotypic traits. The strongest association was detected between AFLP markers with a bud diameter trait, which explained 68% of the variation. Among several polymorphic bands, 14 markers were associated with senescence, 10 with flower diameter and eight with stem length. This approach also led to the identification of seven markers with significant association to full bloom. Therefore, these markers can be used for the genetic improvement of the ornamental value of Chrysanthemum after further confirmation. The analysis of the results revealed a number of markers co-associated with different correlated phenotypic traits. The results revealed informative markers that have shown a significant correlation with several traits which could be useful for breeding programs and other analyses associated to future studies of Chrysanthemum.
The Effect of Applying Elements of Instructional Design on Teaching Material for the Subject of Classification of Matter.

The aim of this study was to examine the effect of instructional materials for the subject of classification of matter as solids, liquids and gases that were developed using a holistic instructional design model on student achievement. In the study a pre-test/post-test with control group experimental design was used. The study was conducted in the 2004-2005 school year using a sample of 120 students in the 7 th grade (Experimental group 1=30, Experimental group 2=30, Control group 1=30, and Control group 2=30). At the beginning of the study a prior knowledge test, science attitude scale and Multiple Intelligence Fields Determination Scale were completed by the students. At the end of the study an achievement determination questionnaire was completed by the students in the experimental and control groups. Instructional material including student worksheets, student practice questions and a teacher guide were prepared by the researchers on the Freehand MXa program. In teaching the subject to the experimental groups, a holistic instructional approach was used that combined reliance on multiple intelligence theory, a constructivist approach, deliberate use of analogies and an emphasis on science process skills. In addition, concept maps and an animation were used. The data were analyzed using descriptive statistics, one-way analysis of variance, Cohen’s size effect, and the Scheffe Test with the SPSS 11.00 program at the . 05 significance level. At the beginning of the study, it was found that while there was no statistically significant difference between the students of the experimental and control groups, at the end of the study levels of achievement of the students on this subject in the two experimental groups were higher than both control groups.
Use of Maize Distillers Dried Grains with Solubles (DDGS) in Laying Hen Diets: Trends and Advances

Distiller’s Dried Grains with Solubles (DDGS) as untraditional feedstuff has been available for feed industry for many years and became a nutritional and economical feed ingredient. According to recent studies, DDGS is usually used at low concentrations (10 or 15%) as a feed ingredient in laying hen diets without adverse effects on laying performance, feed utilization, nutrient digestibility, egg quality criteria and economics. Because DDGS became available in feed market in large amounts, the ability of using higher DDGS inclusion rate in poultry feed has become an interest for several researchers and poultry producers. Using such untraditional feedstuffs aims mainly to decrease the feed costs. Researchers assured that feeding higher levels of DDGS could have a significant effect on the cost of feed for poultry producers because of higher availability of DDGS and the current price fluctuations of feed ingredients. On the other hand, beneficial effects of DDGS on the environment have also been reported. These beneficial effects could be represented through mitigating harmful emissions and pollution from manure which provides production within clean atmosphere. Findings from different researches on the use of DDGS as feed ingredient for laying hens are illustrated in this review. Moreover, this study describes advanced information regarding the use of corn DDGS as untraditional feedstuff for laying hens involving its production process and nutritive value along with its useful effects on laying hens production traits, egg quality, apparent digestibility, economics and the impact on the surrounding environment in poultry house.

Basaltic terrain occupies significant areas of eastern Cambodia and occurs in pockets elsewhere in the north, north-east and north-west. Basaltic soils are likely to be prominent in the development of upland cropping; however, the nature and properties of these soils are poorly understood. In studies in Ou Reang Ov district of Kampong Cham province, a previously undescribed brown gravelly clay loam soil was found to be prevalent. In Ou Reang Ov district it comprises about 13 % of the basaltic terrain. It is morphologically distinct from the rice soils described for basaltic terrain (Labansiek and Kompong Siem Soil groups) and occurs on the slopes of basaltic hills and plateau. The Ou Reang Ov Soil group is a newly proposed member of the Cambodian Agronomic Soil Classification. The Ou Reang Ov Soil group is well drained and unsuited to padi rice. Indeed the gravel content of the soil makes field crops prone to drought. Apart from sub-soil acidity in some profiles, other soil chemical properties were generally favourable. Indeed the extractable P levels on Ou Reang Ov soil were generally high. Kaolin and quartz were the dominant minerals in Ou Reang Ov soil although the soil texture suggests that much of the quartz is in silt and clay size fractions. Smectite clay minerals were prevalent even though this soil does not exhibit cracking at the surface when dry. Although occurring on slopes, the Ou Reang Ov soil is relatively resistant to erosion. Overall it is considered to have fair to good capability for cropping, if drought tolerant crops are selected.
The Role of Design Freeze in Product Development

“Freezes” play a major role during product development. Many companies use high-level stage-gateway processes for new product development (NPD), where freezes mark the end point of a development stage: for example, “specification freeze” defines the set of requirements the entire design will be based on, and “design freeze” describes the end point of the design phase at which a technical product description is handed over to production. However, academia seems to have paid little attention to freezes. While freezes are important to industry, only a few papers comment on freezes and describe their use, benefits and drawbacks.
Vulnerability of melanic Daphnia to brown trout predation

The coexistence of melanic Daphnia cf. longispina and facultatively planktivorous brown trout is reported from a clear-water, alpine lake. This co-occurrence is uncommon, presumably due to the vulnerability of pigmented Daphnia to fish predation. Lake Bjornesfjorden (Norway) provided an opportunity to test this assumption. About 20% of the fish caught in gill nets had fed on Daphnia. The trout exerted a marked selection for large-sized Daphnia prey, and a very strong selection for pig- mented individuals relative to transparent ones. The persistence of a pigmented Daphnia population probably relies on limited recruitment and a low stock of the predator, and the availability of more favourable benthic prey organisms.
Passive vibration control in mid-frequency region

This paper deals with passive vibration control of structures exhibiting both long- and short-wavelength deformations within the same frequency range. Such behaviour is often observed in complex build-up structures such as rib-stiffened plates, automotive vehicles, aeroplane fuselages and so on, and is inherent property of any structure comprising of both stiff and flexible structural elements. Addressing both short- and long- wavelength vibrations within the same frequency range is often referred to as the mid-frequency problem, and presents considerable difficulties since it is not amendable for deterministic (e.q. finite element method, FEM) or statistical (statistical energy analysis, SAE) analysis techniques alone. Furthermore, mid-frequency vibrations exhibit intrinsic sensitivity to system uncertainties (e.q. structure variability, uncertainty in boundary conditions). Mid-frequency vibration problem has attracted considerable interest in the past decade, and a number of hybrid FE/SAE methods for predicting the vibration response has been developed. Yet, passive vibration control of the structures exhibiting mid-frequency vibration has not been fully addressed. In this paper, we discuss an optimal passive control technique for a generic mid- frequency vibration problem via multiple tuned mass dampers (TMDs). The problem at hand is tackled as reducer-order optimal H1 control of uncertain system with controller order and structure constraints We address several issues of the proposed approach, such as system uncertainty modelling, applicable optimization algorithms and computational costs. To illustrate the applicability and the efficiency of the proposed approach, we present an example comprising of beam-stiffened plate with multiple TMDs. We also investigate the influence of total TMDs mass, number of TMDs and distribution of individual TMDs resonant frequencies on vibration attenuation efficiency.
ASIATICA EXTRACT INDUCES CELL CYCLE ARREST IN CACO-2 HUMAN COLON CANCER CELLS

Centella asiatica is traditionally a medicinal plant frequently employed in the practice of Thai folk medicine. This study examined the anti-tumor activity of the crude water extract of C. asiatica using human colon adenocarcinoma-derived Caco-2 cells. C. asiatica extract reduced the proliferation rate of Caco-2 cells significantly in a concentrationand time-dependent manner. The mechanism of cancer cell growth inhibition was shown to occur via cell cycle arrest. The extract induced S and G2-M arrest in Caco-2 cells accompanied apoptosis induction. The extract also increased the accumulation of cyclin B1 protein in the cells. These findings indicate that C. asiatica extract inhibited cell proliferation of Caco-2 cells through modification of the cell cycle events and this cell cycle arrest is associated, at least in part, with increased accumulation of cyclin B1 protein.

Studi Analisis Eigenface Dan Eigen Fuzzy Set Untuk Ekstraksi Ciri Bibir Pada Sistem Identifikasi Wajah

This paper compares the performance of eigenface and eigen fuzzy set to extract lip traits. Testing is conducted by implementing the two methods in a face identification system based on lip traits. The database used is primary data that consists of front-face image and lip image. The test result shows that eigenface is more effective with average precisionrecall value 0.22% higher. However, statistical tests show that there are no significant differences between the two methods. An optimal extraction method will be used to develop face identification system based on facial components.
Single domain wall effect on parametric processes via Cherenkov-type phase matching

We report on important influence of single domain wall (DW) of electrically poled ferroelectric crystal on parametric processes via Cherenkov-type phase matching. It shows that the effective nonlinear polarization is confined in DW and its phase velocity can be modulated when incident light is off domain wall's direction. These effects lead to novel Cherenkov second harmonic generation (CSHG) which has no analogue in bulk ferroelectrics. Complex DW-modulated parametric process via Cherenkov-type phase matching, such as Cherenkov sum frequency generation (CSFG), is also demonstrated in DW. We propose that nonlinear coefficient in DW is significantly enhanced.
A Workload Balanced MapReduce Framework on GPU Platforms

Zhang, Yue. M.S.C.E. , Department of Computer Science and Engineering, Wright State University, 2015. A Workload Balanced MapReduce Framework on GPU Platforms. The MapReduce framework is a programming model proposed by Google to process large datasets. It is an efficient framework that can be used in many areas, such as social network, scientific research, electronic business, etc. Hence, more and more MapReduce frameworks are implemented on different platforms, including Phoenix (based on multicore CPU), MapCG (based on GPU), and StreamMR (based on GPU). However, these MapReduce frameworks have limitations, and they cannot handle the collision problem in the map phase, and the unbalanced workload problem in the reduce phase. To improve the performance of the MapReduce framework on GPGPUs, in this thesis, a workload balanced MapReduce framework (B MapCG) on GPUs is proposed and developed based on the MapCG framework, to reduce the number of collisions while inserting key-value pairs in the map phase, and to handle the unbalanced workload problems in the reduce phase. The proposed B MapCG framework is evaluated on the Tesla K40 GPU with four benchmarks and eight different datasets. The experimental results showed that the B MapCG framework achieved big performance improvements for all the four test benchmarks both in the map phase and the reduce phase compared with MapCG.

Biotransformation of citronellol in rose-oxide using cassava wastewater as a medium

A utilizacao de residuo liquido do processamento de mandioca (manipueira) como meio de cultura para a biotransformacao de citronelol por uma linhagem de Penicillum sp foi estudada. A linhagem foi capaz de se desenvolver na presenca do residuo atingindo producao de massa celular da ordem de 25 g/L durante tres dias de contato dos esporos com o meio. Culturas submersas de Penicillium sp desenvolvidas em manipueira foram capazes de converter o substrato a cis- e trans-oxidos de rosa quando as celulas foram transferidas a um meio mineral. Pode-se observar que a producao de oxido de rosa sofreu um aumento maior que 2,4 vezes atraves desse processo em comparacao a utilizacao apenas do meio de manipueira (meio de mandioca). Produtos de auto-oxidacao nao foram identificados nos experimentos controle.
Comparative Analysis of Proactive, Reactive and Hybrid Routing Protocols for Improving Quality of Service in Mobile Ad-Hoc Networks

A Manet is set of wireless mobile nodes that communicate with each other without any dynamic infrastructure or centralized supervision. Each mobile node act as a router which forwards the packets to destination by first sending the packet to the nearest hop, various routing protocol are designed for this purpose. Selecting an appropriate routing protocol holds a significant position in the performance evaluation of wireless network. This paper aims to analyse and compare the performance of well- known On-demand routing protocols Ad hoc On demand Distance Vector (AODV), Table-driven routing protocol Destination Sequenced Distance Vector (DSDV) and Hybrid routing protocol Zone Routing Protocol (ZRP). The simulation environment used for these protocols is Network Simulator 2 (NS- 2). The performance of the three routing protocols is analysed with respect to throughput, minimum delay and routing overhead. The major goal of this study is to analyse the performance of popular MANETs routing protocol. Keywords-AODV, DSDV, MANET, Quality of service, ZRP.
