INVESTIGATION AND IN-VITRO IMMUNOMODULATORY STUDY OF ASPARAGUS RACEMOSUS WILLD ROOTS EXTRACTS

Asparagus racemosus Willd, commonly known as shatavari. It is an important medicinal plant found in tropical and subtropical areas in India. Various parts of the plant were traditionally used by Ayurvedic practitioners for inflammation, hepatic, neurological and certain infectious diseases. In the present study, the root of this plant was subjected to extraction with methanol followed by fractionation with solvents of increasing polarity such as petroleum ether, chloroform, ethyl acetate and methanol using a soxhlet extractor. Later phytochemical screening of crude methanolic extract and its fractions was done to identify active chemicals and studied further their in vitro immunomodulatory activity by using the nitroblue tetrazolium test, phagocytosis of killed Candida albicans, Candidacidal assay and neutrophil locomotion & chemotaxis. The extract and all the fractions were tested at concentrations viz. 5μg/ml, 10μg/ml, 25μg/ml, 50μg/ml and 100μg/ml respectively. Compare to other fractions, the chloroform fraction at high concentration showed predominantly significant (p<0.01) activity on in vitro human neutrophils in all tests, which are comparable to standard (in nitroblue tetrazolium test and neutrophil locomotion & chemotaxis) at different concentration indicating the possible immunostimulating effect. The present study reveals that, the presence of important phytoconstituents holds promise immunomodulatory activity in these fractions.
A New Codebook for Object Category Recognition using SIFT

In this paper a new algorithm for codebook construction is proposed. The codebook has an important task in object category recognition when bag of visual word is used for image representation. Traditional codebook construction methods uses only SIFT descriptor. Hence, they considers only visual similarities. The proposed algorithm considers both keypoint location and category information in addition to SIFT descriptors. The new codebook can be implemented efficiently by k-means clustering. Experimental results confirm the performance of the proposed codebook.
The spatial distribution of workplace accidents in Spain: assessing the role of workplace inspections

This paper analyses the spatial distribution of workplace accidents in Spain and analyses the role of economic and institutional variables in this geographical outcome. After estimating an econometric model that explains regional variation in job accidents incidence, we compute conditional regional distributions of workplace accidents under the assumption of no regional variation in workplace inspections. Results show that much of the regional differences in severe and fatal accidents are explained by different inspection intensities. This calls for a regional homogenization of the inspection activities, in contrast to the current situation.
Influência do herbicida glyphosate na comunidade de plantas daninhas na região agrícola de Rio Verde, Goiás

The increasing use of glyphosate in Brazil has increased the selection pressure on species of weeds tolerant and resistant to this herbicide. This study aimed to evaluate the influence of glyphosate use pattern in the population dynamics of weeds in soybeans in thirty-five sampling areas of different properties. These areas were classified as to the number of applications and equivalent amount of glyphosate acid. We used the square-inventory method in thirty-five sampling areas in the 2012/2013 harvest. The structural parameters relative frequency, abundance and value indicator of individuals number and dry weight of shoot were calculated. The graphical representation of the differences of the floristic composition was performed by the non-metric multidimensional scaling technique, with distances of Sorensen. The multi response permutation procedures test was used to test hypotheses of differences in floristic composition. The occurrence of typical species of each treatment was evaluated by the indicator value using the Monte Carlo test (p<0,05). The floristic composition of the number of plants differ between areas using average standards of glyphosate (six applications or 6001 to 8000 g ha -1 of acid equivalent) compared to very low standard areas (four or five applications or 2000 to 4000 g ha -1 of a.i.). The Gnaphalium coarctatum, Eugenia sp. , Rumex acetosella and Spermacoce latifolia, Digitaria horizontalis, Urochloa decumbens, Panicum maximum , Gossypum hirsutum and Indigofera hirsuta species showed significant indicator value of environments with different levels of use of glyphosate. Different glyphosate usage patterns exerted influence on the floristic composition of weeds in soybean areas evaluated.
Artificial Intrusion Detection Techniques: A Survey

Networking has become the most integral part of our cyber society. Everyone wants to connect themselves with each other. With the advancement of network technology, we find this most vulnerable to breach and take information and once information reaches to the wrong hands it can do terrible things. During recent years, number of attacks on networks have been increased which drew the attention of many researchers on this field. There have been many researches on intrusion detection lately. Many methods have been devised which are really very useful but they can only detect the attacks which already took place. These methods will always fail whenever there is a foreign attack which is not famous or which is new to the networking world. In order to detect new intrusions in the network, researchers have devised artificial intelligence technique for Intrusion detection prevention system. In this paper we are going to cover what types evolutionary techniques have been devised and their significance and modification.
Comparative utilization of phytoplankton and vascular plant detritus by the cockle Cerastoderma edule: digestive responses during diet acclimation

Contribution to the Theme Section 'Directions in bivalve feeding' ABSTRACT: Physiological components of food absorption (rates of particle clearance and ingestion and absorption efficiencies) were recorded in the cockles Cerastoderma edule fed variable concen- tration diets of phytoplankton (Isochrysis galbana) and detritus from salt-marsh vascular plants (Spartina maritina), after 2 and 12 d of acclimation to these diets. Corresponding digestive processes were also analysed, including determinations of gut passage time of food, gut fullness (GF) and digestive investments, the latter measured in terms of both metabolic faecal losses (MFL) and enzyme activities of the digestive glands. Digestive responses to increasing availability of phytoplankton included faster processing of food particles coupled to improved hydrolytic capacity of digestive glands that resulted in increased gut performance. Compared to phytoplankton, detritus utilization was constrained in the short-term by its refractory behaviour to digestion and the magnitude of meta- bolic faecal losses experienced by cockles fed these food materials. However, increased GF achieved during acclimation to detrital diets compensated for reduced digestibility, allowing for more food to be processed and thus cancelling out the effects of reduced passage time (and the consequent decline in absorption efficiency). Induction of the appropriate set of carbohydrases during the acclimation process resulted in increased amounts of reducing sugars released from natural substrates, with the additional benefit of diminishing the losses of endogenous materials accompanying each cycle of intracellular digestion.
The growth rhythm and height growth of seedlings of Siberian (Larix sibirica Ledeb.) and Dahurian (Larix gmelinii Rupr.) larch provenances in greenhouse conditions.

The aim of this study was to determine whether the growth rhythm and height growth differ between various larch provenances grown in greenhouse conditions. We also investigated whether the geographic and climatic conditions at the origin of the provenance could explain the possible differences between the provenances. The study material consisted of 16 Russian Siberian (Larix sibirica Ledeb.) and Dahurian larch (Larix gmelinii Rupr.) provenances and four seed sources from Finland as comparison lots. The growth rhythm differences were clearest between the southern and northern provenances; the southern provenances grew for a longer period and the proportion of late summer height growth was larger. Autumn colouration also developed later in these provenances. In the Russian larch material the provenances with a longer growing period had greater height growth. In the whole material the relationship was not so linear due to the deviating behaviour of the comparison material. Several of the Russian larch provenances were taller than the Finnish comparison seed lots, although the difference was not statistically significant. However, the growth of these provenances must be followed for a much longer period in field trials before any conclusions can be drawn about their usability in practical forestry.
Critical Pedagogy in an EFL Teaching Context: An Ignis Fatuus or an Alternative Approach?.

Second language acquisition theory has prompted methods from the Audio-Lingual Method, through Communicative Language Teaching, to Task-Based Teaching, all of which seem to be effective and authoritative for the classroom. But there are some problems with these approaches; they are to be implemented in EFL situations. First, they view language as "object" or merely focus on "methodology". Second, they often fail to link language with local socio-cultural, political and linguistic environment and neglect student student’s needs, objectives and interest. They are often concerned with the what (grammatical and communicative competence) and how (methodology) of teaching, rather than the "why", "how", and "who" of instruction.
Moving Pedestrian Detection Using Normed Proposals and Key Points Matching

Occlusion detection and automatic adaption of a generic pedestrian detector to a specific scene are difficult problems in intelligent monitoring. When a detector trained in a specific scene is applied on a new scene, its accuracy will decrease greatly. To solve this problem, we propose a new detection algorithm in which motion regions of interest based on motion information are obtained quickly by a flash-bit computing method. Also we focus on the case in which a single target converts to be a difficult one due to multiple overlapping between pedestrians. Key points with BRISK feature which computed and saved before are used to match difficult targets in occlusions. Normed proposals which proved to have higher confidence are used to correct the location and shape of detection windows, results in a five percent increasing of detection accuracy. Results of comparative experiments of five different detectors on three motion pedestrian datasets show that proposed algorithm achieves not only a real time speed, but also the best accuracy that more than half of difficult targets are detected successfully.
Thermal Comfort Zone for Thai People

Radiant cooling system for thermal comfort of Thai people was developed. Questionnaires for subjective experiments were examined for development of radiant cooling system for thermal comfort. Thermal sensation, humid sensation and air movement sensation were used for thermal comfort assessment. The Predicted Mean Vote (PMV) value was used for thermal comfort evaluation and it was observed that the PMV values are in the comfortable ranges during 18:00 to 10:00 for air velocity 0.2 m/s and 0.4 m/s. Comfortable periods are extended for higher air velocity. Neutral temperatures are in the ranges of 26.44℃-33.60℃. The percentage number of dissatisfied (PPD) value for each air velocity was also investigate and the value of PPD is five for zero value of PMV. Simulation and experimental results were evaluated by using three indicators, namely, the coefficient of variation (CV), the mean bias error (MBE) and Chi-Square (x2). The values of CV, MBE and (x2) for mean radiant temperature are 14.52%, 1.54% and 3.95℃, respectively. Zones of acceptable thermal environment were developed for Thai People. Results revealed that the comfortable zones of Thai people are in the ranges of relative humidity 50% 70% and effective temperatures (ET) 24℃ 27℃.

Corruption, privatisation and the distribution of income in Latin America

This paper presents new evidence on income inequality in Latin America over the period 1981-2000. Using a panel data methodology, we find that a reduction in corruption is associated with a rise in inequality. This counterintuitive result can be explained by privatisation. Privatisation removes industries from government influence (and corruption) and worsens income inequality as new owners strive for efficiency and profits. The paper argues that structural reform policies aimed primarily at achieving positive and increasing growth rates do not adequately address the income distribution problem.
Modelling and Characterization of Magnetic Microfibers

Polymer fibers of varying microfluidic properties can be fabricated in a lab setting. Fibers coated with paramagnetic particles act like slender paramagnetic beams. These fiber moves in a magnetic field. Thus polymer fibers coated with paramagnetic particles can be used as actuators in various microfluidic applications, such as DNA separation, droplet manipulation and liquid transport. In order to use the fibers as actuators, it is necessary to model the fiber and develop control strategies. A static model of the paramagnetic fiber based on energy methods is presented in [1]. The model relies on a demagnetizing factors approximation to determine the magnetic field inside the fiber. The first part of the thesis examines the conditions under which the demagnetizing factors approximation holds. The model allows for implementation of simple feedforward control strategies to control the position of the fiber. For implementation of better control algorithms, methods to sense the shape and the tip position of the fiber are required. These sensing methods are also presented here. The model depends on the bending rigidity and magnetic susceptibility of the fiber. Since the fibers can be synthesized in a lab setting, these properties are usually not known. This thesis also presents methods to characterize the bending rigidity of the fiber, based on the sensing methods.
Assessment of the Grazemore dairy cow model to predict performance of grazing dairy cows fed forages

The goal of this work was to determine the accuracy of the Grazemore model to predict milk yield and dry matter intake (DMI) of grazing cows fed pasture and forage supplements. Data were obtained from studies where pasture was complemented with silages, comprising 30-40% of DMI. Twelve dietary mixtures were used in this evaluation. Liveweight, days in milk, pre-grazing mass, allowance and diet composition were collected during the trials and used as inputs. There was a good correlation between actual and predicted milk yield (r2=0.72) and DMI (r2=0.90) by the model when actual production was regressed against predicted responses.
Kriging as a Means of Improving WAAS Availability

The Wide Area Augmentation System (WAAS), an augmentation of the Global Positioning System (GPS), provides safe and reliable use of GPS signals for airline navigation over much of North America. Currently the largest source of positioning error in the system is signal delay caused by the ionosphere. To allow the user to take account of such error, WAAS computes and broadcasts ionospheric vertical delays at a set of regularly-spaced grid points. In addition, WAAS computes and broadcasts a safety-critical integrity bound at each ionospheric grid point (IGP) called the Grid Ionospheric Vertical Error (GIVE). GIVEs are constructed to be sufficiently large to protect the user against positioning error due to the presence of ionospheric irregularity. In the initial operating capability (IOC) of WAAS, the vertical delay estimate at each IGP is determined from a planar fit of neighboring slant delay measurements, projected to vertical using an obliquity factor specified by the standard thin-shell model of the ionosphere. In WAAS Follow-On (WFO) Release 3, however, the vertical delay will be estimated by an established, geo-statistical technique known as kriging. Compared to the planar fit model, the kriging model is found, in general, to match better the observed random structure of the vertical delay. This paper presents the kriging methodology that will be used to estimate the vertical delay and its uncertainty at each IGP, and it assesses the subsequent improvement in WAAS availability enabled by kriging.
An analytical model for the description of the full‐polarimetric sea surface Doppler signature

This paper describes an analytical model of the full-polarimetric sea surface scattering and Doppler signature. The model combines the small-slope-approximation theory (at the second order) with a weak nonlinear sea surface representation. Such a model is used to examine the variation of the Doppler central frequency/bandwidth and of the normalized radar cross section as function of wind speed and direction. The results suggest that the model can be a valuable tool for the accurate observation of sea surface currents.
Oviposition-site preferences of a declining butterfly Erebia medusa (Lepidoptera: Satyrinae) in nutrient-poor grasslands

Butterflies belong to one of the most intensively studied invertebrate groups. However, detailed information on the larval ecology is still lacking in many species. This is especially true for the grass-feeding subfamily Satyrinae, to which our study species, the Woodland Ringlet (Erebia medusa Fabricius, 1787), belongs. At the habitat level, E. medusa exhibits a clear preference for abandoned grasslands with litter accumulation. In this study, we assessed the host-plant and oviposition preferences of E. medusa at the microhabitat level, i.e., within occupied habitat patches, in the Diemel Valley (Central Germany). Only two species of grass, Festuca ovina agg. and F. rubra agg. , were systematically used for oviposition. Egg density was positively correlated with patchiness of herb layer, potential daily length of sunshine, and abandonment. However, the explanatory power of these parameters was low. We attribute this primarily to an ample supply of host plants growing under suitable conditions in the occupied habitat patches of E. medusa. The positive effect of abandonment is probably due to the fact that the average height of oviposition sites of E. medusa is greater than in most other satyrine species, which renders the eggs more vulnerable to mechanical disturbance. Moreover, thick layers of litter, which develop after the cessation of grazing or mowing, might be important as they modify the microclimate at the locations of the immature stages.
Fractal Analysis of Growing Cities and its Relationship with Health Centre Distribution

During recent years, many research group interested in the study of organizational networks from different fields, e.g. studies of behavior of cities growth following the fractal theory. Considering the fractal analysis as a strong tools to analyse the relation between grow of cities and its relation with health center distribution. The propose of this paper is to develop a methodology based on a fractal analysis framework of Chilean public health networks, the population growth of cities and the location of health centers. To produce empirical approach for the analysis of the locations of health centers and its effects. On the other hand the health has been related to other sciences, a clear example is the physics and the mathematics, where we found many studies related with the geometry to understood the nature of the multiple natural shapes, its developed was called fractal nature or mathematic fractal model, this approach consider the different scales. For this reason, we present in this paper some preliminary ideas and some initial results of the analysis of the complex and fractal behavior of urban expansion, and its relation to the location of public health centers through simple counters algorithms and spectral methods using ImaCal software. The study health patterns will become a useful tool for understanding human flow and behavior of health center, where using a traditional measurement as equipment has serious problems and limitations.
Acute Type B Aortic Dissection Presenting as Acute Abdomen

This report presents a surgical repair of a complicated acute type B aortic dissection in a 42-year-old male who suffering from acute abdominal pain initially and the postoperative course was complicated with chylothorax. Acute aortic dissection is a life-threatening vascular emergency and the anterior chest pain radiating to the back is the typical pattern when it attacks suddenly. However, epigastralgia or diffused abdominal pain could be experienced when abdominal branch vessels were involved. Here, we review the literature on acute aortic dissections complicated by involvement of abdominal branch vessels, causing visceral malperfusion or mesenteric ischemia. Vital organ malperfuion, including major cerebral malperfusion, coronary malperfusion and mesenteric ischemia, have been identified as independent risk of in-hospital mortality in several large study enrollments. Despite it still remains debates of strategic and therapeutic options to correct these defects, in-time evaluations and proper examinations should be performed promptly to lower the misdiagnosis rate and reduce the extremely high in-hospital mortality.
