GENETIC VARIABILITY, HERITABILITY AND GENETIC ADVANCE IN CORIANDER (CORIANDRUM SATIVUM L.)

Genetic variability for various characters was studies in one hundred twenty accessions of coriander along with six check varieties. The phenotypic coefficient of variations was higher than corresponding genotypic of variations indicting environmental influence on all the characters. Genotypic and phenotypic coefficient of variations were moderate (21-50%) for umbels per plant and seeds per umbel. The estimate of heritability was moderate (21-50%) to high (>50%) for all the characters. High heritability coupled with high (>50%) genetic advance was observed only for seeds per umbel and other traits such as days to 50% flowering, plant height, umbels per plant and 1000-seed weight showed high heritability combined with moderate (21-50%) genetic advance as percentage of mean, indicating the importance of these traits in yield improvement programme.
Application of Finite Mixture of Logistic Regression for Heterogeneous Merging Behavior Analysis

A finitemixture of logistic regressionmodel (FMLR)was applied to analyze the heterogeneitywithin themerging driver population. This model can automatically provide useful hidden information about the characteristics of the driver population. EM algorithm and Newton-Raphson algorithm were used to estimate the parameters. To accomplish the objective of this study, the FMLR model was applied to a trajectory dataset extracted from the NGSIM dataset and a 2-component FMLR model was identified. The important findings can be summarized as follows: The studied drivers can be classified into two components. One is called Risk-Rejecting Drivers. These drivers are consistent with previous studies and primarily merge in as soon as possible and have a distinct preference for the large gaps. The other is the Risk-Taking Drivers that are much less sensitive to the gap size and pay more attention to surrounding traffic conditions such as the speed of front vehicle in the auxiliary lane and lead space gap between the merging vehicle and its leading vehicles in the auxiliary lane. Risk-Taking Drivers use the auxiliary lane to get to the further downstream or less congested area of the main lane. The proposed model can also produce more precise predicting accuracy than logistic regression model.

Hybrid approach for alignment of a pre-processed three-dimensional point cloud, video, and CAD model using partial point cloud in retrofitting applications

Acquiring the three-dimensional point cloud data of a scene using a laser scanner and the alignment of the point cloud data within a real-time video environment view of a camera is a very new concept and is an efficient method for constructing, monitoring, and retrofitting complex engineering models in heavy industrial plants. This article presents a novel prototype framework for virtual retrofitting applications. The workflow includes an efficient 4-in-1 alignment, beginning with the coordination of pre-processed three-dimensional point cloud data using a partial point cloud from LiDAR and alignment of the pre-processed point cloud within the video scene using a frame-by-frame registering method. Finally, the proposed approach can be utilized in pre-retrofitting applications by pre-generated three-dimensional computer-aided design models virtually retrofitted with the help of a synchronized point cloud, and a video scene is efficiently visualized using a wearable virtual reality device. The prototype method is demonstrated in a real-world setting, using the partial point cloud from LiDAR, pre-processed point cloud data, and video from a two-dimensional camera.
MTRP: Multi-Topology Recovery Protocol

Link and node failure recovery is critical in any production network and recover the failures in times below 50 milliseconds is desired to maintain the quality of real time application. In this paper, we propose the Multi-Topology Recovery Protocol (MTRP) that provides network protection using pre-calculate routes and a multi-topology approach. The protocol was based on the state-of-the-art recovery and protection techniques. MTRP is based on Resilient Routing Layers (RRL) algorithm, used to generate the sub-topology. The MTRP prototype was implemented and tested in a virtualized environment, providing real IP stack in an actual operating system. The tests show that the MTRP provides a quick convergence, below few milliseconds, similar to ring protection protocol for partial mesh topology. MTRP evaluation shows that it also produces recovery paths with costs (distance) almost as low as the primary ones. Keywords-network recovery; protocol; resilience.
Reproducibility of IETA color score for assigning the amount of flow within the endometrium using stored 3 D volumes

Objective: To estimate intraand inter-observer reproducibility for assigning IETA color score for endometrial vascularization by color Doppler. Methods: 68 endometrial 3D volumes from endometrium color Doppler assessment from women with different endometrial pathologies were evaluated by eight different examiners (4 skilled examiners and 4 OB/GYN trainees). One skilled examiner that not participated in the assessment selected the 68 volumes from the database in order to select a balanced number of each IETA score. Each examiner evaluated the 68 endometrial volumes to assign IETA color score (1: absence of vascularization, 2: vascularization low, 3: moderate vascularization, 4: abundant vascularization) using TUI imaging. The analysis repeated 4 weeks later to assess. Interand intra-observer reproducibility was analyzed by calculating weighted kappa index. The second of the measurements made by each observer was used to estimate inter-observer reproducibility. Results: The intra-observer reproducibility was very good for all examiners with a weighted kappa index ranging from 0.84 to 0.91. The inter-observer reproducibility was good or very good for all estimated comparisons with a weighted kappa index ranging from 0.77 0.96, regardless of experience level. Conclusions: The reproducibility for assigning IETA color score for assessing endometrial vascularization using three-dimensional volume is good or very good regardless of the experience of the examiner.
Qualitative and Quantitative Study of Quercetin and Glycyrrhizin in In Vitro Culture of Liquorice ( Glycyrrhiza glabra L . ) and Elicitation with AgNO 3

Liquorice (Glycyrrhiza glabra L.) is a plant that has been considered for a long time due to its valuable secondary metabolites. This study was conducted to obtain quercetin and glycyrrhizin under controlled conditions and the use of silver nitrate (AgNO3) as an elicitor to increase their production. For this purpose, the seeds were cultured in MS media containing various concentrations of AgNO3 (0, 2, 4, 8 and 10 mg L). Quercetin in the aerial parts extract of three-month seedlings prepared with methanol solvent 95% and acetic acid (9:1), and glycyrrhizin in the root extract of four-month seedlings prepared with ethanolic extract (30%) were evaluated qualitatively and quantitatively using HPLC. The results obtained from three replications showed the presence of quercetin and glycyrrhizin in all samples. The amount of quercetin in all samples treated with AgNO3 was significantly higher than control (P≤0.05) and this increase was higher at concentrations of 8 and 10 mg L in comparison with other concentrations. Glycyrrhizin content increased under the influence of different concentrations of AgNO3 as compared to the control; however, this increase was not significant. Our results clearly showed that this method is a practical method to produce and elicit more these compounds with medicinal value.
Shallow semantics for topic-oriented multi-document automatic text summarization

There are presently a number of NLP tools available which can provide semantic information about a sentence. Connexor Machinese Semantics is one of the most elaborate of such tools in terms of the information it provides. It has been hypothesized that semantic analysis of sentences is required in order to make significant improvements in automatic summarization. Elaborate semantic analysis is still not particularly feasible. In this thesis, I will look at what shallow semantic features are available from an off the shelf semantic analysis tool which might improve the responsiveness of a summary. The aim of this work is to use the information made available as an intermediary approach to improving the responsiveness of summaries. While this approach is not likely to perform as well as full semantic analysis, it is considerably easier to achieve and could provide an important stepping stone in the direction of deeper semantic analysis. As a significant portion of this task we develop mechanisms in various programming languages to view, process, and extract relevant information and features from the data.
Stress and Subjective Health of Teachers 1

This article focuses on the psychological contexts of subjective health among teachers in relation to their perception and evaluation of work-related stress in the teaching profession. The research was carried out on a sample of teachers from Czech and Slovak primary schools (.N = 2501) during 2009–2011 using the subjective perception methodology. The aim of the article is to consider the connections between subjective evaluation of stress and health among teachers, and between subjective and objective indicators of individuals’ state of health. The results indicate that there exist negative and statistically signifi cant (1% level) but weak (lower than –0.2) correlations between perceptions of work-related stress and subjective health. This suggests that this relationship is probably mediated by other variables; in our research these were personality factors from the Big Five model (neuroticism and extraversion) and the variables optimism, hardiness and sense of coherence. The connection between subjective and objective health is illustrated by correlation coeffi cients whose values were statistically signifi cant (1 %) yet likewise weak (around 0.2); this suggests that other infl uences are also likely to be involved. 1 This study was carried out as part of the Czech Science Foundation grant project no. 406/09/0726 “Coping with Load by Men and Women”.
A Finite Dimensional Sliding Mode Observer for a Spatially Continuous Process

Modeling and control of systems represented by Partial Differential Equations (PDEs) is an interesting research field as the process under investigation is infinite dimensional and most commonly used techniques are for finite dimensional systems. This paper considers the development of a finite dimensional observer obtained after an appropriate model reduction stage. A sliding mode observer is considered as it utilizes the sign of a quantity and ensures good reconstruction performance. The paper compares the fictitious state variables that are obtained after projecting the instantaneous snapshots on an eigenbasis and the state variables predicted by the observer. The results emphasize that the designed observer functions well on some set of operating conditions, which are elaborated in the paper.
COMPARATIVE BIOCHEMICAL STUDIES ON THE MACROMOLECULAR COMPOSITION , FREE AMINO ACIDS AND ENZYMATIC ASSAY ON THE STING GLAND AND RESERVOIR OF THE EUROPEAN HONEY BEE Apis Mellifera

Apis mellifera is the most commonly domesticated species of honey bees. It probably originated in tropical Africa and spread from there to Northern Europe and East into Asia. This species builds multiple comb nests in dark cavities (like A.cerana), and share a similar social organization and division of labour with other honey bee species (Maa, 1953; Akratanakul, 1976; otis, 1990). The sting of the species is a modification of the female ovipositor, or egg laying apparatus. It is no longer used to lay eggs but instead serves as a weapon of defense. When a honey bee stings, the barbs on the stinger get stuck in the victim, and the stinger is pulled out of the bee’s body. The bee dies shortly after stinging. Queen bees however can sting many times ABSTRACT
Rapid response to anthropogenic climate change by Thuja occidentalis: implications for past climate reconstructions and future climate predictions

Carbon isotope values of leaves (δ13Cleaf) from meta-analyses and growth chamber studies of C3 plants have been used to propose generalized relationships between δ13Cleaf and climate variables such as mean annual precipitation (MAP), atmospheric concentration of carbon dioxide ([CO2]), and other climate variables. These generalized relationships are frequently applied to the fossil record to create paleoclimate reconstructions. Although plant evolution influences biochemistry and response to environmental stress, few studies have assessed species-specific carbon assimilation as it relates to climate outside of a laboratory. We measured δ13Cleaf values and C:N ratios of a wide-ranging evergreen conifer with a long fossil record, Thuja occidentalis (Cupressaceae) collected 1804–2017, in order to maximize potential paleo-applications of our focal species. This high-resolution record represents a natural experiment from pre-Industrial to Industrial times, which spans a range of geologically meaningful [CO2] and δ13Catm values. Δleaf values (carbon isotope discrimination between δ13Catm and δ13Cleaf) remain constant across climate conditions, indicating limited response to environmental stress. Only δ13Cleaf and δ13Catm values showed a strong relationship (linear), thus, δ13Cleaf is an excellent record of carbon isotopic changes in the atmosphere during Industrialization. In contrast with previous free-air concentration enrichment experiments, no relationship was found between C:N ratios and increasing [CO2]. Simultaneously static C:N ratios and Δleaf in light of increasing CO2 highlights plants’ inability to match rapid climate change with increased carbon assimilation as previously expected; Δleaf values are not reliable tools to reconstruct MAP and [CO2], and δ13Cleaf values only decrease with [CO2] in line with atmospheric carbon isotope changes.
Underutilizing Resources for HPC on Clouds

We investigate the effects of shared resources for high-performance computing in a commercial cloud environment where multiple virtual machines share a single hardware node. Although good performance is occasionally obtained, contention degrades the expected performance and introduces significant variance. Using the DGEMM kernel and the HPL benchmark, we show that the underutilization of resources considerably improves expected performance by reducing contention for the CPU and cache space. For instance, for some cluster configurations, the solution is reached almost an order of magnitude earlier on average when the available resources are underutilized. The performance benefits for single node computations are even more impressive: Underutilization improves the expected execution time by two orders of magnitude. Finally, in contrast to unshared clusters, extending underutilized clusters by adding more nodes often improves the execution time by exploiting more parallelism even with a slow interconnect. In the best case execution time, performance was improved enough by underutilizing the nodes to entirely offset the cost of an extra node in the cluster.
Association between Glutathione S ‐ transferases M 1 and Glutathione S ‐ transferases T 1 Gene Polymorphisms and Endometrial Cancer Risk ?

Endometrial cancer (EC) is the most common type of uterine cancer and gynecologic cancer worldwide. Conventionally, the classification of EC risks is major composed of prolonged unopposed estrogen stimulation, partial estrogen against drugs such as tamoxifen, late menopause, nulliparity, and obesity. [1] However, epidemiologic studies showed that the combined effect of environmental factors and genetic factors plays a critical role in the development of EC. Recent evidence, mainly from molecular genetic analyses, suggests that invasive cancer has a substantial hereditary component.
ANALYSIS OF FACTORS AFFECTING EMBRYOGENESIS IN MICROSPORE CULTURES OF BRASSICA CARINATA

Three factors affecting embryogenic processes in microspore culture of Brassica carinata were tested: developmental stage of isolated microspores (late uninucleate to early binucleate), level of the elevated temperature (30; 32 and 25°C) and effect of density 70 000 to 150 000 microspores per 1 ml of the medium. We have developed an efficient and reliable protocol for Brassica carinata microspore embryogenesis. Our results confirmed remarkable effect of all examined factors on the formation and further development of microspore derived embryos, observed in other genotypes from genus Brassica. Optimal values for above mentioned factors were determined in five various genotypes and could largely help to improve the protocol for efficient and rapid production of completely homozygous plants of Brassica carinata.
Patterns of R & D Configuration and Evolution in MNCs Chuanhui

State-of-the-art Global distribution of R&D has been interpreted as a strategic decision of firms who attempt to exploit their innovation advantage to compete in an increasingly globalized environment. However, firms with similar geographic distribution are heterogeneous in their ability to exploit the benefits of geographic reach to enhance the quality of their innovation (Lahiri, 2010). This challenges multinational firms to devise an appropriate technology strategy and to manage the global configuration for R&D accordingly. Research Gap and Theoretical Arguments: According to the dispersion of R&D activities and the degree of cooperation between individual R&D units, Gassmann & von Zedtwitz (1999) suggested a new classification of R&D configuration: ethnocentric centralized, geocentric centralized, polycentric decentralized, R&D hub, and integrated R&D. More recently, Gassmann and von Zedtwitz (2002) identified four archetypical forms of international R&D organization: national treasure, market-driven, technology driven and global. Meanwhile, Birkinshaw (2002) recognized that there are two ways of managing the entire R&D organizational structure: integrated R&D, loosely-coupled. DeSanctis (2002) also proposed three organizational designs which are being used to manage distributed R&D organizations: decentralized, networked and integrated. In recent years, more emerging countries, such as China, Brazil and India, play an important role in the international R&D strategies of many MNCs. While the continued growth of R&D globalization in emerging countries has been highlighted in the literature, little attention has been devoted to the question of whether the configuration patterns have evolved along with the emergence of new R&D destinations. Thus, in my study, I examine the patterns of R&D configuration in MNCs and the evolution. In particular, I investigate whether there is entirely new pattern beyond the scope of the existing literature and co-existence of different patterns of R&D configuration in a large multinational firm.
LEVEL OF ACHIEVEMENT OF LEARNING OBJECTIVES IN NATURAL NUMBERS TEACHING IN THE 4 TH GRADE OF PRIMARY SCHOOL UDC 371 . 314

This paper presents the results of the research on the level of achievement of course objectives in natural numbers teaching in the 4 grade of primary school using the taxonomic model designed for this research purposes. The taxonomic model consists of five levels: recognition, reproduction, comprehension, generalization and application, problem solving. It was aligned with Bloom’s taxonomy in the cognitive domain, and also with the requirements related to the assessment of students’ knowledge presented in the Primary School Mathematics curriculum. A descriptive method in its analytical and classification form was used, whereupon data were obtained on the degree of operationality and classification of learning objectives in terms of concretization, realization and possibility of verifying whether the objectives can be achieved. The survey was conducted on a sample of 315 students of the 4 grade. The obtained results indicate that as the level of complexity based on the taxonomic model increases, the level of achievement of learning objectives regarding natural numbers in the 4 grade of the primary school decreases. Moreover, in the case of two learning objectives, students achieved all levels of complexity, while in the case of three learning objectives students reached the level of comprehension. When it comes to the remaining four learning objectives, they reached the level of reproduction, that is, they acquired only the basic knowledge that each student is supposed to gain at the end of the learning process. The obtained results can contribute to changes in the approaches to teaching contents in the following way: changes and innovation to the mathematics curriculum, identification and formulation of learning goals, evaluation of the level of achievement of learning objectives, more efficient individualization of the learning process, identification of criteria and standards for assessing students’ knowledge, acquiring a more permanent and better-quality knowledge, etc.
: Modeling Systems with OCL at MoDELS 2007

: Other than its ‘platform independence’ the major advantages of OCL over traditional Object Oriented programming languages has been the declarative nature of the language, its powerful navigation facility via the iteration operations, and the availability of tuples as a first class concept. The recent offering from Microsoft of the “Orcas” version of Visual Studio with C# 3.0 and the Linq library provides functionality almost identical to that of OCL. This paper examines and evaluates the controversial thesis that, as a result of C# 3.0, OCL is essentially redundant, having been superseded by the incorporation of its advantageous features into a mainstream programming language.
