A computational tool focusing the optimization of 34.5 and 138 kV overhead lines transmissible power

In recent years studies concerned with the evaluation of different geometrical configurations for transmission overhead lines, aiming at increasing the transmissible power, have been carried through. These new concepts act in the geometric configuration of the conductors, to search for solutions where the distances among phases tend to reduce, whereas the distances between subconductors of the same phase tend to increase. This technology is known as HSIL High Surge Impedance Loading Line.
Big answers from small worlds: a user's guide for protist microcosms as a model system in ecology and evolution

Laboratory microcosm experiments using protists as model organisms have a long tradition and are widely used to investigate general concepts in population biology, community ecology and evolutionary biology. Many variables of interest are measured in order to study processes and patterns at different spatiotemporal scales and across all levels of biological organization. This includes measurements of body size, mobility or abundance, in order to understand population dynamics, dispersal behaviour and ecosystem processes. Also, a variety of manipulations are employed, such as temperature changes or varying connectivity in spatial microcosm networks. Past studies, however, have used varying methods for maintenance, measurement, and manipulation, which hinders across‐study comparisons and meta‐analyses, and the added value they bring. Furthermore, application of techniques such as flow cytometry, image and video analyses, and in situ environmental probes provide novel and improved opportunities to quantify variables of interest at unprecedented precision and temporal resolution. Here, we take the first step towards a standardization of well‐established and novel methods and techniques within the field of protist microcosm experiments. We provide a comprehensive overview of maintenance, measurement and manipulation methods. An extensive supplement contains detailed protocols of all methods, and these protocols also exist in a community updateable online repository. We envision that such a synthesis and standardization of methods will overcome shortcomings and challenges faced by past studies and also promote activities such as meta‐analyses and distributed experiments conducted simultaneously across many different laboratories at a global scale.
Versatile Indian sari: Clothing insulation with different drapes of typical sari ensembles

Author(s): Indraganti, Madhavi; Lee, Juyoun; Zhang, Hui; Arens, Edward | Abstract: The sari is everyday attire for most women throughout the year all across South-Asia. It is a versatile ensemble because, a single set of garments can provide different levels of insulation just by changing the drape. We tested three Indian ensembles of saris (for four drapes) with a thermal manikin following ISO: 9920 protocols. The insulation on all the sixteen body parts and the whole-body were recorded. This provides information for advanced thermal comfort modelling needing clothing insulation at segmentation level.The sari offered a wide range of insulation (0.94 to 0.62) for a given set of garments. Winter ensembles provided 1.11 – 1.39 clo while the summer and monsoon ensembles had 0.62 – 0.96 clo.
MediaSense - an Internet of Things Platform for Scalable and Decentralized Context Sharing and Control

Research in Internet-of-Things infrastructures has so far mainly been focused on connecting sensors and actuators to the Internet, while associating these devices to applications via web services. This has contributed to making the technology accessible in areas such as smart-grid, transport, health, etc. These early successes have hidden the lack of support for sensor-based applications to share information and limitations in support for applications to access sensors and actuators globally. We address these limitations in a novel open-source platform, MediaSense. MediaSense offers scalable, seamless, real-time access to global sensors and actuators via hetero- geneous network infrastructure. This paper presents a set of requirements for Internet-of-Things applications support, an overview of our architecture, and application prototypes created in order to verify the approach in a test bed with users connected from heterogeneous networks.
An In Vitro Technique to Estimate Digestibility of Amino Acids in Dairy Cattle Feeds

Three soybean meal (SBM), 3 SoyPlusRTM (SP), 5 dried distillers' grains with solubles (DDGS), and 5 fishmeal (FM) were obtained from FeedAC, Inc. (Homer, NY) and along with 5 cornsilage hybrid samples (CS), were used in an experiment to calculate total tract digestibility of crude protein (CP) and amino acids (AA). An in vitro procedure was used that incorporated the modified three step procedure (mTSP) developed by Calsamiglia and Stern (1994) and then modified by Gargallo et al. (2006) and the protease incubation procedure developed by McNiven et al. (2001) which replaces the in situ rumen incubation step in the mTSP. In the validation of the procedure correlation coefficients were produced from comparisons of experiments done previously in the same lab with the same feeds (Boucher et al. 2009 a,b&d, Fredin unpublished). Protein feeds had varied but promising results where as the CS sample results were too variable to be used to measure digestibility.
Motif clustering with implications for transcription factor interactions

High-throughput data, for instance ChIP-seq data, measure binding of transcription factors (TFs) or other proteins to DNA and have become a widespread data source for de-novo motif discovery. Often, several ChIP-seq data sets study the same TF under different conditions resulting in several, potentially redundant motifs, which demands for identification and clustering of similar motifs. Here, we propose a refined measure of motif similarity based on the correlation between score profiles on de Bruijn sequences. We demonstrate the utility of the proposed measure in benchmark studies on artificial motifs and motifs discovered from ENCODE ChIP-seq data. We use this measure to cluster motifs discovered from 757 different ENCODE ChIP-seq data sets for 166 TFs and RNA-polymerase II and III. Based on this clustering, we derive a TF interaction network that reflects many known TF-TF interactions, but also reveals novel putative interaction partners.

A cause de la specificite geometrique des cylindres en tant que le substrat de la microfabrication, de nombreuses modifications sont apportees au procede de fabrication 'standard' pour le depot et l'usinage des materiaux en surface du substrat metallique courbe. Le resultat de microfabrication est presente, ainsi que l'analyse et les ameliorations eventuelles du procede actuel.
Mattin, LR and Yau, AMW and McIver, V and James, LJ and Evans, Gethin (2018)The effect of exercise intensity on gastric emptying rate, appetite and gut derived hormone responses after consuming a standardised semi-solid meal

This study investigated the acute circulating gut hormone, appetite and gastric emptying rate responses to a semi-solid meal following exercise at different intensities. Twelve men completed three trials in a randomised-crossover design, consisting of continuous cycling at 70% V̇O2Peak (HIGH), 40% V̇O2Peak (LOW) or rest (CONTROL). Baseline samples were collected after an overnight fast before undertaking the 60 min exercise or rest period, followed by 30 min rest before consumption of a standardised semi-solid meal (~242 kcal). During the 2 h postprandial period, gastric emptying rate of the meal was examined using the 13C-breath test method, appetite was measured using visual analogue scales, and serum concentrations of acylated ghrelin, pancreatic polypeptide, peptide YY, glucagon-like peptide-1, insulin, glucose, triglycerides, total cholesterol and non-esterified fatty acids were assessed. Subjective appetite response was not different between trials (p > 0.05). Half emptying time of the meal was 89 ± 13, 82 ± 8 and 94 ± 31 min on CONTROL, LOW and HIGH, respectively (p = 0.247). In healthy un-trained adult males, responses to exercise at intensities of 70% and 40% V̇O2Peak did not differ to a non-exercise control for measurements of subsequent gastric emptying, circulating gut hormone response or appetite. These results suggest that exercise intensity has little effect on post-exercise appetite response to a semi-solid meal.

Machine learning plays a vital role in health care industry. It is very important in Computer Aided Diagnosis. Computer Aided Diagnosis is a quickly developing dynamic region of research in medicinal industry. The current specialists in machine learning guarantee the enhanced precision of discernment and analysis of diseases. The computers are empowered to think by creating knowledge by learning. This procedure enables the computers to self-learn individually without being explicitly programed by the programmer . There are numerous sorts of Machine Learning Techniques and which are utilized to classify the data sets. They are Supervised, Unsupervised and Semi-Supervised, Reinforcement, deep learning algorithms. The principle point of this paper is to give comparative analysis of supervised learning algorithms in medicinal area and few of the techniques utilized as a part of liver disease prediction.
Genomics of Eucalyptus wood traits

A major focus of our research has been on using molecular technologies to guide breeding for high value wood and fibre traits in eu- calypts. One approach has been to use genomic maps to locate and characterise QTL that control wood and fibre traits. A generic map for euca- lypts has been developed that consists of codominant markers that can be assayed across the major commercial species. Also on the map are candidate genes for traits such as flowering and wood and fibre traits. QTL have been characterised for wood density, fibre length, pulp yield and microfibril angle. A number of these have been validated in a related pedigree. A subset of QTL colocates with candidate genes. Research is now focussed on DNA sequence variation in different parts of these candidate genes and determining if this variation is associated with variation in wood properties. Of particular interest are genes involved in fibre development and cell wall formation. A third approach is to profile the expres- sion of genes in the tissue of interest and determine if this relates to variation in trait performance. Microarrays are being used to relate expression of several thousand genes in xylem tissue to variation in traits such as microfibril angle and density. eucalypt / linkage maps / QTL / candidate genes / xylem / microarrays
Thermal Properties and Energy Utilization of Cassava Meal in Conductive Rotary Drying

In this study the thermal properties and drying behaviour of cassava meal in a conductive rotary dryer was investigated. Cassava flour and gelatinized gari were produced at drying temperatures of 70°C and 90°C, respectively. The activation energy of cassava meal was 49.52 kJ/mol, and the effective moisture diffusivity, thermal conductivity and heat capacity increased with temperature from 1.74x10-10 to 4.51x10-10 m2/s, 0.329 to 0.344 W/m°C and 1.804 to 1.901 kJ/kg°C, respectively. With increase in bulk density of cassava meal from 379.50±2.55 to 464.79±30.38 kg/m3, thermal diffusivity and specific energy consumption decreased from 4.81x10-7 to 3.89x10-7 m2/s and 618.88 to 456 kJ/kg, respectively. The thermal efficiency of the dryer was greater than 31% for both cassava flour and gari. Compared with previous works, performance of the conductive rotary dryer was satisfactory and upgrade of its design will make it suitable for application in the cassava processing industry.
Perceptions of wildlife damage and species conservation: lessons learned from the Utah prairie dog

The Utah prairie dog (Cynomys parvidens), a federally listed threatened species, causes damage to agricultural operations, yet little incentive exists for private landowners to conserve them. Therefore, we surveyed Utah residents to identify stakeholder attitudes regarding prairie dog management. We assessed how perceptions of wildlife damage affect respondent attitudes regarding conservation among agricultural producers, rural residents, and urban residents. Higher levels of perceived wildlife damage were reported for agriculture respondents (79%) than for urban (20%) or rural (45%) respondents. Compensation for damage caused by Utah prairie dogs was supported by those engaged in agricultural production but not by rural or urban respondents. Agricultural producers, rural residents and urban residents all stated a preference for private conservation organizations to fund damage compensation rather than a government agency. Most agricultural respondents (61%) and rural respondents (64%) believed that Utah prairie dogs should be only on public lands. Some agricultural respondents (23%) thought they should be on no land. Attitudes regarding the Utah prairie dog varied, with agricultural producers being the most negative and urban respondents the most positive. The negative attitude of rural residents and agricultural producers probably results from both the damage caused by Utah prairie dogs and land-use restrictions resulting from the species being listed as threatened. Acceptance of Utah prairie dogs by private landowners may be key to the recovery of the species, and our fi ndings suggest that alleviation of damage issues may increase landowner acceptance of conservation measures to protect Utah prairie dogs.
The Impact of E-procurement on the Number of Suppliers

This paper examines how electronic procurement influences the organization of economic transactions. It seeks evidence for ICT-induced changes in how companies organize their activities and whether ICT lead to more competitive and transparent markets. Testing the relationship between the effect of electronic procurement on procurement cost and sourcing strategy, I provide new evidence that electronic procurement leads to more market transactions. This leads to the conclusion that electronic procurement increases market transparency, lowers search and supplier switching costs and improves the management of supply chain and contradicts the predictions that ICT will lead to a dominance of network-like organizational form and an increasing reliance on hybrid forms of organizing economic transactions. Two implications emerge from these results. The first one is relevant for companies engaging in ICT projects. ICT combined with changes in business strategy leads to a reduction of market transaction costs and, as a result, opens up new possibilities in terms of how business activities can be organized and/or how to structure competition in upstream markets. This effect of new technologies is of clear benefit to companies successfully implementing and using new technologies. The second implication is of great importance for companies whose customers implement ICT to intensify competition among suppliers. Changing environment forces them to adapt to new market conditions and look for new ways of maintaining profitability.
Seed germination and seedling morphology of Smilax polyantha (Smilacaceae)

As especies de Smilax L. sao utilizadas na medicina popular brasileira desde o seculo 19 devido as propriedades anti-reumaticas atribuidas aos orgaos subterrâneos de todas as especies. No entanto, ainda hoje, essas especies sao exploradas apenas por extrativismo. Estudos sobre a germinacao e o desenvolvimento dos orgaos subterrâneos podem ser uteis para preservar essas plantas. Apos a germinacao, o desenvolvimento de plântulas de Smilax polyantha foi analisado para compreender a formacao do sistema subterrâneo. Para a analise da ontogenese do sistema subterrâneo foram seccionadas plantas em diferentes estagios de desenvolvimento entre um e doze meses. Uma das caracteristicas mais marcantes desta especie e a presenca de dois sistemas de ramificacao caulinar. A plumula da origem ao primeiro sistema caulinar de ramificacoes com geotropismo negativo. As gemas axilares subterrâneas desse primeiro eixo caulinar originam o segundo eixo caulinar com geotropismo positivo. O crescimento horizontal e o espessamento do orgao subterrâneo dependem do desenvolvimento de gemas axilares de nos basais dos ramos anteriores. A gema cotiledonar nao participa da formacao do caule subterrâneo, como descrito anteriormente na literatura para este genero, mas as gemas axilares basais dos ramos caulinares aereos originam o segundo eixo de ramificacao caulinar subterrâneo. Neste estudo, apos ser discutida a terminologia mais adequada, sugere-se chamar o caule subterrâneo dessas especies de rizoforo.
On the Seasonal Signal of the Filchner Overflow, Weddell Sea, Antarctica

AbstractThe cold ice shelf water (ISW) that formed below the Filchner–Ronne Ice Shelf in the southwestern Weddell Sea, Antarctica, escapes the ice shelf cavity through the Filchner Depression and spills over its sill at a rate of 1.6 Sverdrups (Sv; 1 Sv ≡ 106 m3 s−1), thus contributing significantly to the production of Weddell Sea Bottom Water. Here, the authors examine all available observational data from the region—including five year-long time series of mooring data from the Filchner sill—to examine the seasonal variability of the outflow. The temperature of the ISW outflow is found to vary seasonally by 0.07°C with a maximum in April. The accompanying signal in salinity causes a seasonal signal in density of 0.03–0.04 kg m−3, potentially changing the penetration depth of the ISW plume by more than 500 m. Contrary to recent modeling, the observations show no seasonal variability in outflow velocity. The seasonality observed at the sill is, at least partly, due to the admixture of high-salinity shelf .
Reconciling Csikszentmihalyi's Broader Flow Theory: With Meaning and Value in Digital Games

Flow, the concept developed by Mihaly Csikszentmihalyi over the last forty years or so (see Csikszentmihalyi 1975) has been invoked quite often with respect to the way players engage with digital games (e.g. Baron 2012; Cowley et al. 2008; Sweetser and Wyeth 2005; Brathwaite & Schreiber, 2009; Fullerton, Swain, & Hoffman, 2008; Schell, 2008). However, Kubey & Csikszentmihalyi (2002) have argued that ‘video games’ are in fact likely to promote undesirable experiences of a kind Csikszentmihalyi refers to as ‘entropy’ or unstructured and unsatisfying life experiences. This paper explores Csikszentmihalyi’s greater thesis and examines how a broader reading of Flow theory can potentially help us understand Flow like engagements beyond the simple mechanistic view of challenge explicitly introduce personally expressed cultural values into the conditions of Flow. By doing so we can then provide a value centric analysis and design approach, similar to that of Cockton’s (2004; 2012) proposal, to include values in general software design. That is, the very nature of challenges and rewards needs to be considered in order to investigate how overcoming or receiving such challenges would be positively or negatively perceived by individuals, from particular cultures, holding particular values. Thus we hope that we have dealt with the apparent contradiction in using Csikszentmihalyi’s concept in the study of games despite his criticism of such a move, and have provided some indication of how we can deal with unspecified rewards and the differential perception and engagement with potentially equivalent challenges while still supporting the accepted thesis of Flow.
Alloy effects in GaInN/GaN heterostructures

We show that the large band offsets between GaN and InN and the heavy carrier effective masses preclude the use of the Virtual Crystal Approximation to describe the electronic structure of Ga_(1-x)In_(x)N/GaN heterostructures while this approximation works very well for the Ga_(1-x)In_(x)As/GaAs heterostructures.
Decoupled Closed-Form Solution for Humanoid Lower Limb Kinematics

This paper presents an explicit, omnidirectional, analytical, and decoupled closed-form solution for the lower limb kinematics of the humanoid robot NAO. The paper starts by decoupling the position and orientation analysis from the overall Denavit-Hartenberg (DH) transformation matrices. Here, the joint activation sequence for the DH matrices is based on the geometry of a triangle. Furthermore, the implementation of a forward and a reversed kinematic analysis for the support and swing phase equations is developed to avoid matrix inversion. The allocation of constant transformations allows the position and orientation end-coordinate systems to be aligned with each other. Also, the redefinition of the DH transformations and the use of constraints allow decoupling the shared DOF between the legs and the torso. Finally, a geometric approach to avoid the singularities during the walking process is indicated. Numerical data is presented along with an experimental implementation to prove the validity of the analytical results.
