Simultaneous HPLC Analysis of Arachidonic Acid Metabolites in Biological Samples with Simple Solid Phase Extraction

A reversed-phase high-performance liquid chromatogrphy (RP-HPLC) has been developed to analyze the metabolites of arachidonic acid based on the specificities of ultraviolet absorption of these various metabolites and is sensitive to the nanogram level. This procedure makes it possible to extract complex mixtures of eicosanoids efficiently with a single step and to analyze them simultaneously by RP-HPLC from biological samples using octadesylsilyl silica extraction column and as an internal standard. The cyclooxygenase products {prostaglandin and thromboxane and lipid peroxidation product, isoprostanes, of arachidonic acid were monitored by one isocratic HPLC system at 195 nm wavelength. The lipoxygenase products and 5-hydroxyeicosatetraenoic acid (5-HETE), 12-HETE, 15-HETE} were measured by another isocratic HPLC system at 280 nm for LTs and 235 nm for HETEs. This method provides a simple and reliable way to extract and assess quantitatively the final arachidonic acid metabolites.
Semi-supervised morpheme segmentation without morphological analysis

The premise of unsupervised statistical learning methods lies in a cognitively very plausible assumption that learning starts with an unlabeled dataset. Unfortunately such datasets do not offer scalable performance without some semi-supervision. We use 0.25% of METU-Turkish Corpus for manual segmentation to extract the set of morphemes (and morphs) in its 2 million word database without morphological analysis. Unsupervised segmentations suffer from problems such as oversegmentation of roots and erroneous segmentation of affixes. Our supervision phase first collects information about average root length from a small fragment of the database (5,010 words), then it suggests adjustments to structure learned without supervision, before and after a statistically approximated root, in an HMM+Viterbi unsupervised model of n-grams. The baseline of . 59 f-measure goes up to . 79 with just these two adjustments. Our data is publicly available, and we suggest some avenues for further research.
Recent experiences with implementing dynamic process control and monitoring in the flash smelting process

This year is well on its way, and while the northern hemisphere is moving towards summertime, the southern parts of the world are approaching wintertime. One of the highlights to look forward to in 2013 will be Copper 2013 on 1-4 December returning back to its country of origin, Chile (http://www.cobre2013.cl/index.php/en/). The Copper International Conference will be a good opportunity to meet and get together with leading research and development specialists in the art of copper making from all around the world.
Short communication: Two steps Synthesis of a BODIPY carboxylic-Curcumin

Boron dipyrromethene (BODIPY) carboxylic acid belong to a family of organoboron compounds and widely as fluorescent dye while curcumin is the traditional Chinese medicine to treat various diseases. Curcumin has a maximum absorption peak at wavelength 430 nm but its wavelength perhaps not long enough for photodynamic therapy or other biological applications. Organic synthesis is the major studied in this short communication, so we proposed a synthetic method linking the Boron dipyrromethene (BODIPY) carboxylic acid and curcumin to increase its absorption wavelength. The synthesized product, "BODIPY carboxylic-Curcumin" with 11% yield and characterized by 1H NMR, 13C NMR, HRMS and HPLC. It’s also determined by Ultraviolet-visible (UV-Vis) spectroscopy. This preliminary results as an important starting to decide it for further investigation.
Secondary ice production in Antarctic mixed-phase clouds : an underappreciated process in atmospheric models

Antarctic clouds are among the largest sources of uncertainty in projections of the Antarctic surface energy balance. At the heart of this uncertainty is the poor quantitative understanding of the cloud microphysical structure. In-situ cloud measurements frequently show that ice 25 crystal number concentrations (ICNCs) are much higher than the available ice-nucleating particles, suggesting that secondary ice production (SIP) may be active. Rime-splintering, thought to be the dominant SIP process in summer Antarctic conditions, at temperatures between -8 and -3C, cannot explain the ICNCs observed in ambient clouds. Including a parameterization for SIP due to break-up (BR) from collisions between ice particles in the 30 Weather and Research Forecasting model bridges the gap between observations and simulations, suggesting that BR could account for the enhanced ICNCs in the pristine Antarctic atmosphere. These results are insensitive to uncertainties in primary ice production. The BR mechanism is currently not represented in most weather prediction and climate
Extraction socket preservation using a collagen plug combined with platelet-rich plasma (PRP): A comparative clinico-radiographic study

Background. Alveolar bone remodeling after tooth loss results in reduced ridge dimensions in horizontal and vertical planes. To prevent this, various authors have proposed different ridge preservation techniques. A collagen plug is a novel material that has shown promising results in preserving the alveolar bone. PRP has also yielded favorable outcomes in wound healing and promoted osteoinduction and osteoconduction Methods. Thirty patients of both sexes with an age range of 30–18 years requiring bilateral extraction of teeth with similar tooth root anatomy in the maxilla or mandible were included in the study. The extraction of teeth was carried out atraumatically. The patients’ arches were randomly divided and labeled as the test or control sides. Bone width was measured on both sides. A collagen plug, with PRP, was placed, and the extraction socket was sutured on the test side. The control side was just sutured. A baseline RVG was taken to record the apico-coronal height. The patients were recalled after 10 days for suture removal and evaluation of wound healing. Parameters were re-evaluated at three and six months postoperatively. The data were subjected to t-test and one-way ANOVA. Results. The height of the crestal bone on the grafted side was more when compared to the non-grafted side three and six months after tooth extractions, and the difference was statically significant (P<0.001). No statistically significant difference was seen in the width of the alveolar bone three and six months after tooth extraction (P>0.05). Conclusion. Collagen and PRP provided reasonable socket preservation as simple and inexpensive options as compared to other materials.
A Simple Checkerboard Suppression Technique for Topology Optimisation Using Simulated Annealing

In this paper, a simple technique to prevent checkerboard problem in topology optimisation is presented. The technique is employed along with Simulated Annealing (SA) the universal optimisation method. The objective function used in SA search strategy is obtained from the weighted sum of structural weight, compliance and checkerboard penalty. The developed design approach is implemented on two design case studies. The influence of weighting factors on the obtained optimum results is illustrated.
Designing Anonymous Signature-Based Authenticated Key Exchange Scheme for IoT-Enabled Smart Grid Systems

—Recent technological evolution in the Internet of Things (IoT) age supports better solutions to magnify the management of the power quality and reliability concerns, and imposes the measures of a smart grid. In smart grid environment, a smart meter needs to securely access the services from a service provider via insecure channel. However, since the communication is via public channel, it imposes various security threats by an adversary. To deal to this, in this article we design a new anonymous signature-based authenticated key exchange scheme for IoT-enabled smart grid environment, called AAS-IoTSG. The dynamic smart meter addition phase is also permissible in AAS-IoTSG after initial deployment. The security of AAS-IoTSG has been tested rigorously using formal security analysis under the Real-Or-Random (ROR) model which is one of the broadly-accepted standard random oracle models, formal security veriﬁcation under the broadly-used Automated Validation of Internet Security Protocols and Applications (AVISPA) tool and also using informal security analysis. Finally, an exhaustive comparative study unveils that AAS-IoTSG supports better security & functionality features and requires less communication & computation overheads as compared to the existing state-of-art authentication mechanisms in smart grid systems.
Towards Obtaining Affect-Based Proxies for Attentional Behaviour in TEL

: Current multimodal studies have a common limitation of not being able to scale up the implications since the apparatus used is not scalable. In this paper, we propose a simple method to find measurements from scalable data modes such as facial data and examine the measures in richer and more granular data modes like eye-tracking that they correspond most closely to. In other words, we find pervasive proxies to the measurements that have been reported to be obtrusive. We exemplify this approach using eye-tracking and facial data from two different studies.
Long-term stock performance of Chinese IPOs

Previous US studies show evidence that stocks of firms that go public significantly underperform their matched peers (Loughran and Ritter, 1995; Ritter, 1991; Ang et al., 2007). Long-term underperformance has been observed also in many non-US countries (Aggarwal et al., 1993; Álvarez and González, 2001; Aussenegg, 2000; Cai and Wei, 1997; Drobetz et al., 2005; Keloharju; 1993, Kim et al., 1995; Levis, 1993; Omran, 2005; Page and Reyneke, 1997). The existence of long-term underperformance still remains as puzzle in finance field, although numerous works have been devoted to this issue (Brav and Gompers, 1997; Teoh et al., 1998; Kahle, 2000; Schultz 2003; Guo et al., 2006). Researchers have recently paid much attention to Chinese IPOs that have some unique characteristics (Chan et al., 2004; Huang and Song, 2005; Mok and Hui, 1998; Yu and TSE, 2006; Wang, 2005). However, only a limited number of studies address long-term stock underperformance of Chinese IPOs. As an exception, Chan et al. (2004) document that A-share IPOs experience only small underperformance, with the wealth relatives
Assessment of Cervical Cancer Molecular-Based Screening Tools; HPV-DNA Detection versus E6/E7 mRNA Testing; First Report of a Prospective Cohort Study among Iranian Women

Background: Human papillomavirus (HPV) has been found as the most considerable causes of cervical cancer. Recently, several molecular methods have been introduced to increase the accuracy of the screening programs and decrease the mortality rate. Among these methods, mRNA-based methods have more advantages as they assess the expression level of HPV E6 and E7 oncogenic mRNAs. This study aimed to evaluate the results of HPV RNA- and DNA-based methods among Iranian women population with normal cytology results. Methods: Overall, 4640 women were enrolled referred to the Gynecology Oncology Ward of Vali-e-Asr Hospital, private and academic clinics, Tehran, Iran from Jan 2016 to Apr 2018. To assess the HPV-DNA infection INNO-LiPA® HPV Genotyping Extra-II kit was used. For HPV-RNA assessment, Aptima HPV Assay and in house HPV-RNA genotyping methods were applied. Results: The positivity rates of HPV infection according to DNA- and RNA-based methods were 18.0% and 11.2%, respectively (P<0.001). The positive predictive value, negative predictive value, specificity and sensitivity of DNA-based method in contrast with RNA-based method were 59.2% (56.6–61.6), 99.4% (99.0–99.6), 91.7% (90.8–92.6) and 95.2% (93.0–96.9) respectively. Conclusion: At the present study for prognosis of cervical cancer, RNA-based method seemed to be more specific in contrast to DNA-based method. Patient follow up and further studies will be conducted in order to clarify the clinical sensitivity and specificity of the two methods.
Density of herbivorous fish and intensity of herbivory are influenced by proximity to coral reefs

Ecosystems can be profoundly influenced by consumers, sometimes to the extent that the entire appearance of the ecosystem is altered. We used remotely sensed images to identify distinctive halos around patch reefs in the lagoon of Ningaloo Reef, the world’s largest fringing coral reef. Thirty-four halos were identified along the length of Ningaloo Reef. Five halos located within a 122 km tract of the reef were investigated. The halos extended >90 m from each central patch reef and were found to be associated with a high biomass of, and intensive grazing by, herbivorous fish, especially the large-bodied Kyphosus sydneyanus. Large brown algae mainly of the genera Sargassum, Dictyopteris and Lobophora were the dominant macroalgae, but were almost absent immediately adjacent to the patch reefs. Other taxa of herbivorous fish were present near the patch reefs, including Naso spp. , Siganus spp. and Scarus spp. , but the biomass of each was low and none were significant contributors to grazing. The sizes of the halos reported here are tenfold larger than those previously reported in coral reef systems and are likely to be the result of intensive herbivory by K. sydneyanus.
Isolation and identification of a yeast strain involved in the degradation of Marrakech olive mill wastewater

Yeasts are widely used in various sectors of biomedical research, biotechnologies and environmental contexts. During the treatment of olive oil mill wastewater (OMW) by yeasts, extensive degradation of the polyphenols responsible for the highly toxic nature of this effluent occurs. In this study, one yeast isolate was selected for its ability to use the phenolic compounds in OMW as the sole carbon source for growth. The treatment of OMW using this isolate reduced the levels of polyphenols by about 50% and the fats by over 80%. Analysis of the polyphenol pool by HPLC revealed the presence of 6 compounds, most of which had disappeared after 5 and 25 days of treatment. Using API ID 32C, the taxonomic study of the selected isolate was found to be 99.9% identical to Candida valida. However, the molecular data using the Rep-PCR technique showed 83.6% similarity to Pichia membranifaciens and 80.6% to Pichia anomala.
On trend robustness and end-point issues for New Zealand business cycle facts

We present new empirical evidence on trend robustness and end-point issues, utilising the macroeconomic data set investigated in McKelvie and Hall (2012). We consider the relative merits of non-robust Hodrick-Prescott (HP) and robust loess (LOcal regrESSion) trend filtering methods, and assess the sensitivity of HP1600 stylised facts to (i) the considerable “supply shock” deviations from trend associated with New Zealand’s 1992 power crisis, and (ii) an alternative HP100 specification and the loess approach. On end-point issues, we assess value-added from the use of seven-point triangular moving average and HP1600 filters, relative to insights from a 21-quarter uniform moving average filter.

A New Record of Neosartorya aureola Isolated from Field Soil in Korea

A new species of Neosartorya was recovered during investigation of the fungal community in soil samples collected from different locations in Korea; Neosartorya aureola KNU14-7 was isolated for the first time from field soil in Korea and identified based on the internal transcribed spacer region of rDNA and morphological characteristics. The species has not been officially reported from Korea and we report it here with description and figures.
Equilibrium of field reversed configurations with rotation. III. Two space dimensions and one type of ion

Self-consistent solutions of the Vlasov–Maxwell equations are obtained. They involve rigid rotor distributions. This selection is justified on physical grounds. For this selection the Vlasov equation can be replaced by moment equations which terminate without any additional assumptions. For one-dimensional equilibria with one type of ion these equations have exact solutions. A complete equilibrium solution appropriate to a field reversed configuration with rotation can be obtained by solving a generalized Grad–Shafranov equation for the flux function. From this solution all other physical quantities can be determined. A Green’s function method is developed to solve this equation, which provides a basis for an iterative solution. This method has the advantage that at every iteration the boundary conditions are satisfied. In this paper cylindrical geometry with one space dimension and one type of ion is considered, where analytic solutions are available. The convergence of the Green’s function method is est.
APPLICATION OF DIRECT METHODS OF OPTIMIZING STORAGE RING DYNAMIC AND MOMENTUM APERTURES

Optimization of dynamic and momentum apertures is one of the most challenging problems in storage ring design. For storage-ring-based x-ray sources, large dynamic aperture is important in obtaining high injection efficiency, which leads to efficient operation and protects components from radiation damage. X-ray sources require large momentum aperture to obtain sufficiently long Touschek lifetimes with low-emittance beams. We have developed effective methods of optimizing dynamic and momentum apertures that rely directly on tracking using a moderately sized Linux cluster. After reviewing the method, we describe examples of its application to APS operations, upgrades, and next-generation storage rings.

Effects of Pulsed White LED Light on the Growth of Lettuce.

Lettuce was grown under pulsed white LED light at variation pulse cycles and DT ratios (illuminated period/cycle), and the relative growth rate per unit luminous energy and photosynthetic rate were examined. Both the growth rate and photosynthetic rate were generally increased (except at a pulse cycle of 10ms and a DT ratio of 50%) compared with continuous illumination. Particularly, both the growth rate and photosynthetic rate were increased by 20% or more at a pulse cycle of 400μs and a DT ratio of 50%. A further slight increase in the growth rate was observed when the DT ratio was 33%. These results may be explained by the presence of a period of 200μs duration in which light is unnecessary (period of electron transport) in the light reaction of photosynthesis. This study supports the feasibility of LED plant factories.

Development of wireless sensor network for environment monitoring Applications

This paper presents a self-organizing wireless sensor network that can be used for environmental surveillance tasks, like wildlife behavioural studies. The parameters of interest that are measured and recorded are temperature, humidity, illumination and the motion of living objects inside the span of the network. An accurate time-synchronization algorithm has been implemented and tested successfully. A vital task during the whole development process was to keep the power consumption to a minimum, since the used nodes are battery powered. This paper shows that the TelosB mote combined with the TinyOS operating system provides an easy to implement infrastructure establishment. The TelosB has been extended with additional hardware, without disturbing the low power operation. The extension board can be fully controlled via software and has a sleep state where the current consumption drops to less than 0.1 A
Power Optimization in 8-Bit Binary Divider

Nowadays, power consumption is the primary concern for the designing of digital systems (VLSI circuits). Power consumption is a considerable issue in the emergence of green computing also. The need for low power design has become a major issue in high performance digital system such binary dividers, etc. To meet the power requirement in today’s world, scientists are focusing on designs for low power applications. The failure of reducing power consumption below a specific point can lead to the increase in the cost of systems, reduction in the market life of the systems along with other problems. An optimization of power dissipation can be achieved through various methods. Binary division is an important part of binary arithmetic. An 8-bit binary divider is capable of dividing two 8-bit numbers of base 2 i.e., binary numbers. Therefore, this paper proposes to solve this problem of power consumption in 8-bit binary divider. Thereby, optimize the power used by an 8-bit binary divider by using and further modifying the Goldschmidt Algorithm.
Slice‐torus link invariants, combinatorial invariants and positivity conditions

We prove some necessary conditions for a link to be either concordant to a quasi‐positive link, quasi‐positive, positive or the closure of a positive braid. The main applications of our results are a characterisation of positive links with unlinking numbers 1 and 2, and a combinatorial criterion to test if a positive link is the closure of a positive braid. Finally, we compile a table of all positive and positive‐braid prime links with less than 8 crossings.
Estimating Animal Abundance with Capture Frequency Data

I describe a new method for estimating the number of animals in a closed population with capture-recapture data under a heterogeneity model. The model is applied to capture frequency records of striped skunk (Mephitis mephitis), eastern chipmunk (Tamias striatus), eastern cottontail (Sylvilagus floridanus), and taxicab populations. I also report the results of a Monte Carlo simulation to assess the relative merits of the proposed moment estimator and the jackknife estimator. If many individuals are caught more than twice, the jackknife estimator is superior to the proposed moment estimator. However, when the mean capture probability is small, so that most captured animals are caught only 1-2 times in the samples, the moment estimator is usually less biased than the jackknife estimator. The mean coverage probability of the confidence interval associated with the moment estimator is also closer to the nominal level than that of the
