The feature of the Anan-Kihoku direct-current transmission line (overhead line)

The Anan-Kihoku DC transmission line was built in order to transmit a part of electric power generated in the Tachibanawan thermal power plants of Tokushima Prefecture to the Kansai area. The DC overhead line of the Anan-Kihoku DC transmission line is an extra high voltage transmission and one of the largest DC transmission line, which passes through a seashore area, in the world in terms of it's design and scale. Moreover, we consider the environment because this line is located close to residential areas.
Long-Range Transport of Polluted Urban Air-Masses

Based on two case studies, the process of large-scale transport of a polluted air mass northward of Tokyo is described. Comparison of oxidant concentrations with meteorological data reveals that the polluted air mass produced along the coastal area of Tokyo is transported about 200km by a low-level jet whose core is located around the 950mb level. The stable layer formed between the 800mb and 900mb levels also plays an important role in this process.
Possibilistic NDT data fusion for evaluating concrete structures

A new application of data fusion is presented within the context of national research project named SENSO. The aim is to improve evaluation of indicators or pathologies of in situ concrete structures by combining measurements from different NDE techniques (radar, electrical resistivity and capacity, infrared thermography, impact echo and ultrasounds). Every non-destructive measurement is likely to provide an estimation of the unknown indicators with a certain confidence that is function of its reliability and its sensitivity to each indicator. When the estimations converge data fusion improves final confidence. In case of disagreement conflict can be managed by specific operators. We develop an adapted solution based on possibility theory that is particularly used in case of imprecise and uncertain data. This theory is very flexible in term of data representations and fusion operators and then requires adapted choices at every step of fusion process. Results are presented for simultaneous evaluation of water saturation and porosity ratio. They show that the chosen adaptative operator function of reliability is appropriate to the problem.
XK469, a selective topoisomerase IIb poison

XK469 (NSC 697887) is a synthetic quinoxaline phenoxypropionic acid derivative that possesses unusual solid tumor selectivity and activity against multidrug-resistant cancer cells. We report here that XK469 and its S(2) and R(1)-isomers induce reversible proteinDNA crosslinks in mammalian cells. Under protein denaturing conditions, the protein-DNA crosslinks are rendered irreversible and stable to DNA banding by CsCl gradient ultracentrifugation. Several lines of evidence indicate that the primary target of XK469 is topoisomerase IIb. Preferential targeting of topoisomerase IIb may explain the solid tumor selectivity of XK469 and its analogs because solid tumors, unlike leukemias, often have large populations of cells in the G1yG0 phases of the cell cycle in which topoisomerase IIb is high whereas topoisomerase IIa, the primary target of many leukemia selective drugs, is low.
Simian Virus 40 Large T Antigen DNA Helicase

The ATPase of SV40 large T antigen (T antigen) which is essential for the replication of SV40 minichromosomes was recently shown to be functionally related to a newly discovered DNA helicase activity. The T antigen helicase unwinds DNA duplices of several kilobase pairs in a reaction depending on the presence of hydrolyzable riboor deoxyribonucleoside triphosphates. The in vitro rate of movement through duplex DNA was found to be about 100 base pairs/min at 37 OC. For DNA unwinding, T antigen requires a 3’single strand extension of a partially double-stranded substrate and invades the double strand section processively, in a 3’ to 5’ direction. The minimum length of the single-stranded tail was determined to be less than 5 nucleotides. Unwinding studies in the presence of the Escherichia coli single strand-specific DNAbinding protein and competition experiments indicate that T antigen helicase binds preferentially at the single-stranded/double-stranded DNA junction. This DNA structure is therefore proposed to serve as an entry site for the T antigen helicase. Previously reported data suggest that T antigen is the replicative helicase of the SV40 minichromosome. The results presented here are consistent with these findings and im* ply that T antigen migrates actively and processively along the template for the leading strand.
The use of a wireless sensor network to monitor the spectrum in urban areas

Wireless sensor networks are a tool increasingly used to monitor various environmental parameters. They can also be used for monitoring the electromagnetic spectrum. Wireless sensors, due to their small size, typically have simplified radio receivers with reduced sensitivity and use small antennas. As a result, their effective performance area is similarly limited. This is especially important in urban areas where there are various kinds of adverse propagation phenomena related to area coverage. The aim of the article is to present the phenomena in the wireless sensor networks and propose criteria and methods to optimize their deployment to ensure maximizing the probability of detection of emissions, minimization of unmonitored areas and to provide the necessary hardware redundancy in the priority areas.
P53 mutation profile of esophageal squamous cell carcinomas of patients from outheastern Brazil

Esophageal cancer (EC) is among the 10 most common and fatal malignacies in the world, presenting a marked geographic variation in incidence rates between and within different countries. The TP53 tumor suppressor gene is highly mutated in esophageal tumors and its mutation pattern can offer clues to the etiopathology of the tumor. As Brazil presents one of the highest incidence areas in the West, a deeper knowledge of the molecular mechanisms related to EC development in the Brazilian population is needed. We analyzed the mutation profile of 110 esophageal squamous cell carcinomas (ESCC) of patients from Southeastern Brazil (Rio de Janeiro and São Paulo) and collected data regarding alcohol intake and tobacco smoking. We detected 41 mutations in tumor samples from 38 patients. There was no association between quamous cell carcinoma utations sophagus razil mutation frequency and tobacco smoking or alcohol drinking. The most frequently mutated codons were 179, 214, 220 and 248. Codons 179, 220 and 248 are hot-spots for ESCC, but codon 214 presents only 0.7% of the mutations registered in the IARC database. The mutation profile revealed a high percentage of mutations at A:T base pairs (34.1%) followed by deletions (17.1%). We concluded that the mutation profile detected in this study is different from that of patients from Southern Brazil but very similar to that previously seen in French patients, being characterized by a high frequency of mutations at A:T base ciated pairs, which may be asso
Aproximación a un modelo contextual para calidad de datos en agricultura de precisión

Precision agriculture is a farming management concept, based on the crop variability in the field; it comprises several stages: data collection, information processing and decision-making. After an extensive review of the literature, it appears that data quality control is an important process in precision agriculture and can be considered in the data collection process. This paper makes an approach to data architecture quality control by applying the contextual information of the acquisition system (sad) and environment context information. This approach can provide the sad the capability to understand the situations of their environment in order to improve the quality of data for decision-making.
Consumption of foods containing significant amounts of antioxidants may help the human body reduce oxidative damage related to ageing and diseases, such as atherosclerosis, cancer and cirrhosis

Soybean and its products became one of the most important functional foods due to its bioactive compounds (isoflavones and bioactive peptides), which have a greet health benefits to human being. In this study, it was prepared a fermented soybean natto with different treatments: drying natto with oven, solar, undervacuum, and extracting them with different solvents to check its antioxidant and antimicrobial activities. Results showed that, acetonitrile extract had the highest amount of peptides followed by methanol extract then water came in the last order. On the other hand, acetonitrile extract had the strongest antioxidant and antimicrobial activities, meanwhile water and methanol extracts had a close effect in general, but still methanol extract had the higher activities than water extract. Methanol extracted all of total isoflavones and some of bioactive peptides, acetonitrile extracted bioactive compounds and some of isoflavones. Upon correlation of these results, it was found that the highest antioxidant and antimicrobial activities excess in acetonitril extract. Therefore, it was assumed that the antioxidant and antimicrobial activities of natto came from both, isoflavones and bioactive peptides, but bioactive peptides had stronger activities.
Role of structure and electron mobilization in enhanced ethanol sensing by Al doped SnO 2 nanoparticles

Improvement in sensing performance by metal oxide based materials have usually been achieved by doping, morphology tuning, particle size tailoring or porosity modification. The existing models of band bending and grain boundary depletion layer that explain chemiresistive sensing address the above issues in terms of qualitative electronic behaviour. However for thick film sensors in particular, there is a clear demarcation between surface and bulk. Thus the concept of gross electronic distribution needs refinement in terms of variable behavior of electrons in surface and bulk so that the role of different layers in a sensor film are distinguishable. Using the case of improved 98.2% ethanol sensing response by paramagnetic aluminium doped tin oxide mesoporous nano-systems, we have demonstrated how Al doping promotes difference in electronic behavior in surface and bulk of thick film sensors, complementing existing charge depletion model. The 4 fold improved sensing responses by Sn 0.947 Al 0.144 O 1.881 and Sn 0.869 Al 0.242 O 1.888 as compared to tin oxide have been explained in terms of shortening of unit cell by virtue of aluminium doping, and the 2.4 fold improved sensing response by Sn 0.869 Al 0.242 O 1.888 as compared to Sn 0.947 Al 0.144 O 1.881 has been explained by surface and bulk electron mobilization. Considering the conceptual inclusiveness of correlation studied, it is expected to be applicable in explaing sensing mechanisms based on electron mobilization in other metal oxide sensor systems also.
Broadband Equal Power Divider

This paper presents the design of broadband two way equal power divider in microstrip medium with defected ground structure suitable for broadband communication systems. Quarter wave broadside coupled lines are used in the place of conventional transformers widely used in the popular Wilkinson power dividers. The proposed power divider structure takes the advantage of top and bottom layers of the microstrip medium to create broadside coupled line configuration using defected ground plane. The floating conductor in the bottom layer plays a critical role in achieving the band select characteristics. Experimental results of two way equal power divider designed using the proposed structure has been verified against the full wave simulations. The isolation between the paths is more than 20dB and the return loss at each port is better than 15dB across the desired band of 3GHz to 8GHz.
Underwater vehicle positioning with correlation sonar

Deals with accurate positioning of an underwater vehicle with respect to the sea bottom. The principle uses the spatial correlation of bottom reverberation signals between successive sonar pulses to measure array displacement, as in correlation log. The horizontal translation is estimated from ping to ping and combined with heading sensor information to reconstruct the complete trajectory. This reconstructed trajectory has been compared with a reference positioning system. Experimental results prove that this method enables an accurate estimation of the underwater vehicle displacements. The standard deviation between the estimated displacement and the reference one (for frequencies around 25 kHz) ranges from 1 mm (static) to 5 mm (dynamic).
Draft Alarm calls of the same individual vary during a response to the same predator in Gunnison ’ s prairie dogs

Many animals emit vocalizations in a repetitive series but are all the calls within a series structurally the same? To answer this question, we recorded the barks of adult female Gunnison’s prairie dogs (Cynomys gunnisoni Baird 1855) during 5 min experimental presentations of several terrestrial stimuli. We measured eight variables (primarily pitch and duration measures) of the first, middle, and last barks in each bout of barking produced by each of 24 females, as well as the duration of inter-bout intervals, the number of barks per bout, and the rate of barking per bout. We found that first barks were significantly longer and higher pitched than middle or last barks. Some of these differences were affected by the number of barks in a bout. Regardless of bark position, barks became longer and lower-pitched in later bouts, and inter-bout intervals, number of barks per bout, and the rate of barking per bout all declined in later bouts. Our results show that bark structure can vary even within a single context, and within a short time period. Thus, variation due to call position within and across bouts of calling is a potentially important confound for studies examining other sources of acoustic variation.
POLARIZED NEUTRON STUDY OF THE MAGNETIZATION DENSITY DISTRIBUTION WITHIN A C o F e^ COLLOIDAL PARTICLE* DENSITY IN A CoFe.O

Magnetization and Mossbauer data suggest that a magnetically anomalous region exists within finely divided CoFe_0, particles when coated with oleic acid [1]. We have undertaken an x-ray and a polarized neutron powder diffraction study of these samples with and without the surfactant coating in an attempt to locate and characterize this anomalous zone. The shape of neutron scans of the (4,0,0) reflection are independent of polarization indicating that the reflecting crystallites are uniformly magnetized. Magnetization calculated from the peak flipping ratio is characteristic of uncoated rather than coated particles in both cases. Scan widths of both x-rays and neutrons are narrower for the sample from which the chemisorbed surfactant has been largely removed indicating an increase in the size of the coherent lattice of a crystallite. These observations are consistent with the existence of a highly strained surface layer roughly 10 Angstroms thick characterized by pinned spins associated with the presence of oleic acid, which relaxes to a more normal lattice structure upon boiling off. the,surfactant.

Spatial Dimension Analysis based on Real-time Signal: Safety Evaluation Improvement of Pipeline and Pump System

This paper, describing a pipeline and pump system (PPS) as a set of interconnected network with real-time signal updating, presents a spatial dimension analysis (SDA). It is conceived as a scheme that pumps and pipelines run involving a firm relationship between each other, specially, in problems where detecting the precise status of abnormal changes is the main goal. Negative Pressure Wave method based on logical inference is applied to extract abnormal signals captured from the supervisory control and data acquisition. We use Local Mean Decomposition combined with Cubic B-Spline Interpolation (CLMD) to reduce the singular points of the instantaneous frequency avoiding spectrum distortions. SDA can determine the trend of the system and be applied to achieve better estimation accuracy of state variables.
Pro-inflammatory activation of endothelial cells and its counter-regulation

In the setting of infection or wound healing, a tightly controlled pro-inflammatory and pro-thrombotic conversion of the endothelial phenotype is a beneficial biological response which helps to combat infection and renew organ integrity. However, prolonged endothelial activation, which has escaped control mechanisms of the host, may set off unfavorable sequelae, such as atherosclerosis and intravascular thrombosis (13). Factors responsible for endothelial homeostasis involve both biochemical and biomechanical stimuli. The former include inflammatory cytokines, namely tumor necrosis factor-α (TNFα) and interleukin-1β (IL-1β), both of them known also as “proximal” cytokines which, in their turn, induce endothelial expression of adhesion molecules (e.g., E-selectin, vascular cell adhesion molecule-1 or VCAM-1, intercellular adhesion molecule-1 or ICAM-1) and pro-coagulant factors, most importantly tissue factor (TF). The net result is known as endothelial dysfunction (12, 18). The central mediator which converges most inflammatory stimuli is the transcription factor nuclear factor κB (NF-κB). Its activation leads to the disruption of the noninflammatory, non-thrombogenic vascular lining, which is transformed into a pro-inflammatory, pro-thrombotic endothelial surface (16). On the other hand, biomechanical factors, namely laminar shear stress (LSS), induce the expression of various protective factors, the most prominent ones being endothelial NOS (eNOS) and thrombomodulin (TM). Both of them are essential for regulation of vascular tone and maintenance of the quiescent state of endothelial cells (4, 25). In those areas of the vasculature where laminar shear stress does not fit in with its physiological range, expression of NF-κB is substantially enhanced (10). Consequently, these vascular segments are prone to the development of atherosclerosis. For example, branch points of the vascular tree are exposed to chaotic blood flow patterns, which are entirely distinct from regular laminar shear stress. Therefore, these branch points are highly susceptible to the formation of atherosclerotic lesions (19).
Formative Assessment Practice: Insight into Three Latvian Universities

Taking into account that formative assessment promotes learning and there is a lack of evaluation data on such type of assessment in Latvian institutions of higher education, at the beginning of 2015 the research was undertaken with the aim of investigating the assessment practice of university lecturers. The questionnaire was used as the main research instrument. The paper presents the analysis of data on three Latvian largest universities: Riga Stradiņš University, Riga Technical University, and University of Latvia. Conclusions are made about assessment purposes, ways of use of assessment information, frequency of grading, feedback types, and other assessment aspects.
America Calling: A Social History of the Telephone to 1940

From the Publisher: The telephone looms large in our lives, as ever present in modern societies as cars and television. Claude Fischer presents the first social history of this vital but little-studied technologyhow we encountered, tested, and ultimately embraced it with enthusiasm. Using telephone ads, oral histories, telephone industry correspondence, and statistical data, Fischer's work is a colorful exploration of how, when, and why Americans started communicating in this radically new manner. Studying three California communities, Fischer uncovers how the telephone became integrated into the private worlds and community activities of average Americans in the first decades of this century. Women were especially avid in their use, a phenomenon which the industry first vigorously discouraged and then later wholeheartedly promoted. Again and again Fischer finds that the telephone supported a wide-ranging network of social relations and played a crucial role in community life, especially for women, from organizing children's relationships and church activities to alleviating the loneliness and boredom of rural life. Deftly written and meticulously researched, America Calling adds an important new chapter to the social history of our nation and illuminates a fundamental aspect of cultural modernism that is integral to contemporary life. Author Biography: Claude S. Fischer is Professor of Sociology at the University of California, Berkeley, and the author of To Dwell among Fris: Personal Networks in Town and City (1982) and The Urban Experience (1984).
Nucleartransferfrom somatic cells: applications in farmanimal species

The reconstruction of mammalian embryos by transfer of a blastomere nucleus to an enucleated oocyte or zygote allows for the production of genetically identical individuals. This has advantages for research (that is, as biological controls) and commercial applications (that is, multiplication of genetically valuable livestock). However, the number of offspring that can be produced from a single embryo is limited both by the number of blastomeres (embryos at the 32-64-cell stage are the most widely used in farm animal species) and the limited efficiency of the nuclear transfer procedure. The ability to produce live offspring by nuclear transfer from cells that can be propagated and maintained in culture offers many advantages, including the production of many identical offspring over an extended period (since cultured cells can be frozen and stored indefinitely) and the ability to modify genetically or to select populations of cells of specific genotypes or phenotypes before embryo reconstruction. This objective has been achieved with the production of lambs using nuclei from cultured cells established from embryonic, fetal and adult material. In addition, lambs transgenic for human factor IX have been produced from fetal fibroblasts transfected and selected in culture.
