Influence of spice and wine based marinades on bovine Biceps femoris muscle tenderness

Fresh beef slices were marinated by immersion in marinades based on dry red wine, lime-tree honey, salt, spices and seasoning plants as thyme ( Thymus vulgaris ), marjoram ( Majorana hortensis ), garlic ( Allium sativum ) and horseradish ( Armoracia rusticana ). Control samples were prepared without marinating treatment but packed and stored in the same conditions as marinated samples. After marination, meat pieces were packed under vacuum and stored at 4°C for 12 days. The combined effects of spices and marination on beef tenderness were evaluated by monitoring pH evolution, the protein and collagen degree of hydrolysis and tenderness. Experimental data indicated that marination weaken beef meat structure, producing improvement of functional properties of adult beef. Marinades use lead for an increase in the protein nitrogen fraction, free amino acids and hydroxyproline contents in boiled beef cuts. A significant increase in tenderness by hardness measurement was observed in the samples marinated and boiled, as compared with the control. Key words : Acidic marination, beef meat, marinating time, meat hardness, pH.
Quantification of phytic acid in grains

This report describes the validation of a cost effective method for quantifying phytic acid in grains, namely, rice and wheat, using UV/Vis spectroscopy. Background information describing phytic acid and its impact on human biological systems and hence the importance of its analysis is included in this report. The validation method involved a range of tests to determine accuracy, precision and reproducibility of the method. Multiple sample matrices were used including standards and spiked samples as described in the validation plan and criteria in Appendix 2. The method employed a commercially available assay kit from Megazyme® and was found to give accurate reliable data according to the performance characteristics attained. This method also has the potential for transfer to laboratories with limited resources, in particular developing countries. It is applicable to survey scale and small batch analysis owing to its relatively low start up and running costs, fast analysis time and ease of instrument set up for each analytical batch compared to established methods using ion chromatography.
Land urbanization in Central Italy: 50 years of evolution

The increasingly fast pace in urban conversion of land over the past 50 years in Italy is a phenomenon that is still difficult to quantify reliably owing to the chronic lack of knowledge at every territorial level, from national to municipal. This article describes the results of a study on the features of urbanization in the 1950s in the peninsular regions of Central Italy, based on uniform historical maps of the entire country. The historical data were compared from a qualitative and quantitative viewpoint with the present-day geography of settlements. Interesting information has emerged on possible significant thresholds in the relationship between demography and urban use of land, in addition to data on landscape effects to be construed as signs of specific trends underway today and scarcely taken into account by land management tools.
Effect of Surfactants and Polymers on Stability and Antibacterial Activity of Silver Nanoparticles (NPs)

In this first systematic study, we describe the influence of various surfactants and polymers on aggregation stability and antibacterial activity of silver nanoparticles (NPs) prepared by a modified Tollens process. The surfactant/polymer stabilizing effect was monitored using the newly established method based on a titration of the aqueous dispersion of the silver NPs by aqueous solution of poly(diallyldimethylammonium) chloride (PDDA). The aggregation process was evaluated by the dynamic light scattering (DLS) and UV/vis spectra measurements and finally confirmed by TEM. Among all of the investigated modifiers, two surfactants (sodium dodecyl sulfate-SDS and polyoxyethylenesorbitane monooleate-Tween 80) and one polymer (polyvinylpyrrolidone-PVP 360) exhibit superior stabilization of the silver NP dispersions against the process of aggregation. The differences in the stabilization ability of various tested substances are discussed with respect to their structure and possible mechanism of the surface inte.
A WIDEBAND QUADRATURE POWER DIVIDER/COMBINER AND ITS APPLICATION TO AN IMPROVED BALANCED AMPLIFIER

In this paper, a novel broadband quadrature power divider and its robust design method are presented. The QPD consists of a two-section power divider in combination with a 90-degree difierential phase shifter. The two-section power divider is calculated to provide equal power split, high output port isolation, and good return loss at all three ports. The difierential phase shifter consists of a composed right/left handed transmission line and pure-right handed transmission line named CRLHu-TL and PRHd-TL, respectively. The CRLHu-TL is divided into two parts; one of them consists of a pure-left handed section whose parasitic pad efiects are represented by means of a pure right handed section named PRHp. On the other hand, the PRHd- TL is composed by a microstrip transmission line of characteristic impedance 50› and electrical length 50 - and two sections equivalents to PRHp. The proposed circuit is applied to develop a broadband balanced amplifler with measured fractional bandwidth (FBW) of 124.4% at the center frequency of 2GHz.
Identification and quantification of polyphenolic compounds in underutilized fruits (Star fruit and Egg fruit) using HPLC

The study was aimed to investigate the antioxidant capacity, total phenolics, total flavonoids and polyphenolic compounds of two common underutilized fruits namely, star fruit and egg fruit. Results showed that, the star fruit extract had higher total phenolics content (161.56±9.24 mg GAE/100 gm FWB) and DPPH radical scavenging ability (91.77±8.68 mg ascorbic acid equivalent antioxidant activity (AAEAA) /100 gm fresh weight basis (FWB) with low IC50 value = 0.6 mg/ml compared to egg fruit extract which had a low phenolics content (152.45±8.75 mg gallic acid equivalent (GAE) /100 gm FWB) as well as lesser DPPH radical scavenging activity (87.21±6.32 mg AAEAA/100 gm FWB) with the IC50 value = 0.88 mg/ml. Total flavonoids content was 72±2.69 and 109.73±5.91 mg quercetin equivalent (QE) /100 gm FWB for star fruit and egg fruit, respectively. Polyphenolic compounds were identified and quantified using HPLC and the data revealed the abundance of gallic acid; quercetin; ferulic acid and epi-catechin in star fruit and egg fruit extracts as well. Overall, the higher potency of star fruit in terms of radical scavenging effects is due to higher content of total phenolics that of egg fruit. In conclusion, the results obtained from our study indicates the star fruit and egg fruit are a good source of phytochemical properties, which are nutritionally prominent for their antioxidant activities and defensive functions against diseases caused by oxidative stress, therefore can be used in functional food formulations.
FAST KEMENY CONSENSUS BY SEARCHING OVER STANDARD MATRICES DISTANCED TO THE AVERAGED EXPERT RANKING BY MINIMAL DIFFERENCE

Background. The problem of ranking a finite set of objects is considered. Objective. The goal is to develop an algorithm that would let speed up the search of the Kemeny consensus along with substantiation of a metric to compare rankings. Methods. An approach for aggregating experts’ rankings is suggested and substantiated. Also a metric to compare rankings is suggested and substantiated. Results. The developed algorithm finds a set of Kemeny rankings much faster than the classical straightforward search. Also this set often contains a single Kemeny consensus, what fails by the straightforward search. Besides, a single Kemeny consensus is determined at one stroke if the averaged expert ranking turns out acyclic. Thus the problem of selecting a single Kemeny consensus is solved. Conclusions. For 10 objects and more, where most known approaches become intractable, the algorithm still is tractable due to searching over only those standard matrices whose distance to the first ranking differs minimally from the distance between this ranking and the averaged expert ranking.
The catenary degree of Krull monoids I

Let H be a Krull monoid with finite class group G such that every class contains a prime divisor (for example, a ring of integers in an algebraic number field or a holomorphy ring in an algebraic function field). The catenary degree c(H) of H is the smallest integer N with the following property: for each a 2 H and each two factorizations z, z 0 of a, there exist factorizations z = z0, . , zk = z 0 of a such that, for each i 2 (1, k), zi arises from zi−1 by replacing at most N atoms from zi−1 by at most N new atoms. Under a very mild condition on the Davenport constant of G, we establish a new and simple characterization of the catenary degree. This characterization gives a new structural understanding of the catenary degree. In particular, it clarifies the relationship between c(H) and the set of distances of H and opens the way towards obtaining more detailed results on the catenary degree. As first applications, we give a new upper bound on c(H) and characterize when c(H) � 4.

Impact of Relay Selection on Dual-hop Relay Communication Systems in Rayleigh Fading Channels

Recently, many studies have been performed on the relay communication networks in order to effectively improve the performance of communication systems in wireless fading channels. However, previous researches have not relatively focused on the case when there is only an indirect path to the destination (i.e. source-relay-destination path) without the direct route between the source and the destination. In this paper, we evaluate and compare the performance of a dual-hop relay communication system in accordance with the relay selection when there is only indirect path to the destination. We also analyze the strengths and weaknesses of each relay selection strategies. Our simulation results show that the partial channel information, the entire channel information, and the effect of the presence and exchange information between the relays via the backhaul make an effect on the relay selection. In addition, the system performance has a significant difference according to these channel information and system complexity.
Evaluation of the Delivery QoS Characteristics of Gigabit Ethernet Switches

The event selection system for ATLAS 1 is designed to perform realtime image processing on particle collision data equivalent to 2 TB/s. This data is ltered by a multi-level architecture, resulting in 200 GB/s of data analysed by a distributed system consisting of several thousand PCs and switches. As part of our ongoing work on this system, we performed tests on several Gigabit Ethernet switches manufactured by market leaders, using our custom-built test equipment. We analysed the implications of running network devices at, and just beyond, saturation while deploying service dieren tiation mechanisms. We quantied the quality degradation that trac o ws experienced when passing through switches. We focused on emergent properties in saturation, including fairness and delit y to expectations. We discuss the ideals for switch behaviour and compare them against the observed behaviour of real implementations of dieren tiation mechanisms in switches. This creates a generic benchmark, which is independent of the switch internals.
Research, part of a Special Feature on Effects of Roads and Traffic on Wildlife Populations and Landscape Function Modeling the Effect of Traffic Calming on Local Animal Population Persistence

A steady growth in traffic volumes in industrialized countries with dense human populations is expected, especially on minor roads. As a consequence, the fragmentation of wildlife populations will increase dramatically. In human-dominated landscapes, typically minor roads occur in high densities, and animals encounter them frequently. Traffic calming is a new approach to mitigate negative impacts by reducing traffic volumes and speeds on minor roads at a regional scale. This leads to a distinction between roads with low volumes as being part of the traffic-calmed area, whereas roads with bundled traffic are located around this area. Within the traffic-calmed area, volumes and speeds can be decreased substantially; this is predicted to decrease the disturbance and mortality risk for animals. Thus far, data on the effects of traffic calming on wildlife population persistence remain scarce. Using metapopulation theory, we derived a model to estimate thresholds in the size of traffic-calmed areas and traffic volumes that may allow persistent populations. Our model suggests that traffic calming largely increases the persistence of roe deer in a landscape with a dense road network. Our modeling results show trade-offs between traffic volume on roads within the traffic-calmed area and both the area of habitat available for this species in the traffic- calmed area and the size of the traffic-calmed area. These results suggest ways to mitigate the fragmentation of wildlife habitat by road networks and their expected traffic volumes.
Interplay of polarization fields and Auger recombination in the efficiency droop of nitride light-emitting diodes

We use theoretical modeling to investigate the effect of polarization fields and non-radiative Auger recombination on the efficiency-droop and green-gap problems of polar and nonpolar nitride light-emitting diodes. The dependence of radiative and nonradiative recombination rates on electron-hole wave-function overlap is analyzed. Device designs that minimize the polarization fields lead to higher efficiency, not because the internal quantum efficiency is improved at a given carrier density but because they can be operated at a lower carrier density for a given current density.
Probing the cosmic web: Intercluster filament detection using gravitational lensing

The problem of detecting dark matter filaments in the cosmic web is considered. Weak lensing is an ideal probe of dark matter, and therefore forms the basis of particularly promising detection methods. We consider and develop a number of weak lensing techniques that could be used to detect filaments in individual or stacked cluster fields, and apply them to synthetic lensing data sets in the fields of clusters from the Millennium Simulation. These techniques are multipole moments of the shear and convergence, mass reconstruction and parametrized fits to filament mass profiles using a Markov chain Monte Carlo approach. In particular, two new filament detection techniques are explored (multipole shear filters and Markov chain Monte Carlo mass profile fits), and we outline the quality of data required to be able to identify and quantify filament profiles. We also consider the effects of large-scale structure on filament detection. We conclude that using these techniques, there will be realistic prospects of detecting filaments in data from future space-based missions. The methods presented in this paper will be of great use in the identification of dark matter filaments in future surveys.
New data concerning the coralligenous atolls of cap corse: an attempt to shed light on their origin

A new coralligenous morphotype named ‘atolls’ was discovered in 2011 in northern Cap Corse (Western Mediterranean Sea). With the aim of inventorying and characterizing these structures, and to attempt to shed light on their origins, two oceanographic campaigns (using e.g. side scan sonar, multibeam echosounder, sparker, ROV and submarine with 3D photogrammetry) were carried out in 2013 and 2014, in this sector, and in the south of the island in search of similar structures. Off Cap Corse, nearly one thousand atolls were identified between 105 and 130 m depth; the majority of them are situated between 110 and 125 m depth. These atolls are generally grouped (several tens to several hundred) and are to be found in two main sectors, situated between 22 and 31 km from the coast. They occur on subhorizontal bottoms, in rocky depressions occupied by coastal detritic bottom, and are 1 to 2 m thick. The average size of these atolls ranges from 20 to 25 m in diameter, but a few smaller or more extensive structures have been identified. The height of the central core ranges from 0.5 to 3.0 m, the intermediate zone, which surrounds this core, presents a width of about 10 m, and the exterior crown has a width of 1 to 5 m. No atoll was found along the south coast although the topography is similar (bathymetric patterns, presence of a seamount). Several typologies have been evidenced; these typologies could correspond to atolls at different stages of evolution in relation to phenomena of bioerosion or bioconstruction. Furthermore, the occurrence of ‘fossil coralligenous’ formations, between 138 and 140 m depth, with still living rhodoliths at the summit, might support the hypothesis of a biological origin, with the original formation occurring during a period when the sea level was lower, several thousand years ago.
Single Phase Clock Distribution using Low Power VLSI Technology

: Normally the clock distribution network will consume about 70% of the total power consumed by the IC because this is the only signal which has the highest activity. Basically for a multi clock domain network we develop a multiple PLL to cater the need, but it consumes more power. So, the main aim of this project is developing a low power single clock multiband network which will supply for the multi clock domain network. It is highly useful and recommended for communication applications like Bluetooth, Zigbee, and WLAN. It is modeled using Verilog simulated using Modelsim and implemented in Xilinx.
INTEGRATING HETEROGENEOUS ONTOLOGIES USING FUZZY RULE BASED SYSTEMS AND BOOSTING ALGORITHM

Due to the immense usage of Internet, the user search and browsing experience is enhanced by retrieving more relevant information. In order to increase the efficiency of retrieval of relevant information, Query Expansion technique is used. Query expansion is a process of generating semantically similar terms related to the original query terms, which is used to bridge the gap between the user query and the required information. Ontologies (OWL files) are used to find the related terms for query expansion. Ontologies are suitable for classifying and defining the concepts, relations, domain, classification rules and so forth. But OWL becomes less suitable in domains where the concepts that are to be represented have not a precise definition. During ontology integration each and every OWL file will use different vocabularies which result in uncertainity.To overcome this uncertainty and retrieve the similarity between concepts in different ontology, fuzzy logic and fuzzy rules are used. To calculate the similarity between two concepts from two different ontologies, two different similarity measures are used. First, to calculate the structural similarity between two concepts from two different ontologies, Path based similarity (Wu & Palmer) measure is used. Secondly, to calculate the semantic similarity between two concepts from two different ontologies, Linguistic similarity measure is used. Finally, the similarity is calculated through fuzzy rules. The results obtained from the fuzzy system are further optimized using Boosting Algorithm like AdaBoost and RankBoost Algorithms. Finally, the results obtained from the Fuzzy System, AdaBoost algorithm and RankBoost algorithms are compared. Based on the experiments carried out RankBoost Algorithm retrieves more accurate results when compared to AdaBoost Algorithm and Fuzzy System. The Proposed methodology is tested with both user-defined dataset as well as benchmark dataset from OAEI. This method of query expansion has a wider scope in knowledge searches, Natural Language Processing etc.
The Effect of Tobramycin on Femoral Stem Migration : A 2 Year RSA Study

INTRODUCTION Approximately 1% of all primary hip replacements become infected within one year of surgery; most of these eventually require revision [1]. Attempts have been made to reduce the risk of early infection by adding antibiotic powder to the bone cement at the time of surgery [2-4]. Large cohort studies have shown this technique to be associated with a lower risk of revision [2, 5]. Unfortunately, not only are these cohort studies subject to confounding, but the outcome measure of revision may in fact reflect the sum of a decreased revision rate for infection combined with an increased revision rate for aseptic loosening because of unrecognized changes in cement properties induced by the antibiotics. The purpose of this study is to determine if the addition of tobramycin antibiotic powder to cement for primary hip replacement surgery increases the risk of long term aseptic loosening as predicted by implant micromotion detected by radiostereometric analysis (RSA).
Feature Level Fusion using Multi-wavelet Based Iris Feature Extraction

A new approach for the iris recognition based on feature level fusion using multi-wavelet transform is presented in this paper. It specifically uses the combined wavelet transform with multi-wavelet on the unique features obtained from the grey level iris images. It is composed of iris image acquisition, preprocessing, feature extraction and classifier design for matching process. The algorithm for iris feature extraction is based on texture analysis by using combination of wavelets and multi-wavelets transform. Multi-wavelet is extremely effective to analyze mutational and singular signals. It selects spatial directions and the energy is basically concentrated in low frequency section. Compared with existing methods, our method extracts 2-dementional information of iris which is scale, translation and rotation invariant. The fused iris image with combination of wavelets and multi-wavelets provide better accuracy and iris recognition rate.
Comparative Study on Thermal Stability and Optical Properties of PANI / CdS and PANI / PbS nanocomposit e

PANI/CdS and PANI/PbS nanocomposite has been prepared using chemical oxidation technique. The prepared products were characterized by FT-IR, Transmission electron Microscopy,UV-Spectra and TGA thermogram. FTIR absorption band at 415 cm -1 indicated the presence CdS and PbS nanoparticles in the polymer matrix.TEM showed the CdS and PbS particles are in nanorange with the average diameter of 21 nm. Thermo gravimetric analysis clearly indicated the increased in thermal stability of nanocomposite than the pure PANI. The appearance of characteristic absorption bands around 280, and 450 nm in the UV–Vis spectra confirms the formation of conducting emeraldine salt.
