Deciphering the potentiality of some elite aromatic rice landraces of North East India

A field experiment was conducted at the research farm of Sripat Singh college, Jiaganj,West Bengal taking eight rice landraces with two aromatic rice cultivars viz., Biroin and Gandhibiroin of Bagbari village, Karimganj, Assam for the assessment and to study magnitude of genetic variability based on fifteen agro-morphological traits including one biochemical trait. Data on qualitative traits were recorded following DUS test and significant variability was found for the traits like leaf anthocyanin colouration, flag leaf attitude, time of heading and basal leaf sheath coloration. Quantitative traits were analyzed and maximum variability was found for the traits like leaf length, number of grains panicle-1, seedling height and grain yield plant-1. Results showed that high estimates of heritability coupled with high GCV and high genetic advance were found in case of grain yield per plant, number of grains panicle-1, seedling height and crude protein plant-1. The higher genotypic and phenotypic coefficient of variation was found for the traits like grain yield, crude protein number of grains panicle-1, leaf breadth, seedling height and grain breadth. Results also showed that the grain yield plant-1 had a highly positive correlation with number of grains panicle (r=0.823)-1 followed by 1000 grain weight (r=0.704) and leaf breadth (r = 0.552). Also, leaf breadth (r = 921), flag leaf angle (r = 0.804), grain length (r=0.700), grain L/B ratio (r = 0.625) and grain yield (r = 0.410) had maximum correlation with the leaf length. Hence, these experimental observations would be beneficial for any rice breeding programme to choose the desirable trait for crop improvement programme choosing the appropriate traits of interest from traditional rice having aromatic feature.
Refractive errors in albino children in Brazzaville

We evaluated refractive disorders in Albino children of Brazzaville and assessed their impact on the visual acuity of these children. Patients and method: Our study was conducted at the University Hospital of Brazzaville in October 2018 as part of a special program of the Congolese Association of Albinos aimed at providing glasses free of charge to albino children. This was a cross-sectional study of 32 children with oculocutaneous albinism. All children received a complete ophthalmological examination. Ametropia was measured by cycloplegic autorefraction performed approximately 45-60 minutes after topical instillation of 3 drops of 1% cyclopentolate administered 5 minutes apart. Results: All children had nystagmus, including 2 cases with strabismus (6.25%). All children had astigmatism, 56.25% of whom were hypermetropic. The mean corrected visual acuity in the better eye was 0.18+/-0.14. The Mean uncorrected visual acuity in the better eye was 0.33+/-0.15. The improvement in visual acuity after correction was statistically significant P=0.002. Conclusion: Albinism is associated with a variety of ocular anomalies including ametropia. Hypermetropic astigmatism was the most common refractive error identified in our series. Correction of this ametropia results in a statistically significant improvement in visual acuity. Introduction Albinism is a group of inherited disorders that are characterized by a reduction or absence of melanin pigment in tissues, in conjunction with ocular and visual pathway developmental abnormalities. The most characteristic manifestation of albinism is related to hypopigmentation in the visual system and/or the skin and teguments. This lack of production of melanin is associated with specific changes in the eye such as foveal hypoplasia and misrouting of optic fibres from the retina to the visual cortex [1]. These changes explain the low visual acuity that presents from birth. In addition, albinism is also associated with refractive disorders and reduced visual acuity [2]. The purpose of this study is to determine the refractive disorders in children of Albino Brazzaville and to appreciate their impact on the visual acuity of these children.

Report on the 5 th International Meeting of the IUGS Lower Cretaceous Ammonite Working Group , the Kilian Group ( Ankara , Turkey , 31 st August 2013 )

The 5th meeting of the IUGS Lower Cretaceous Ammonite Working Group (the Kilian Group) held in Ankara, Turkey, 31st August 2013, discussed the Mediterranean ammonite zonation, and its calibration with different ammonite zonal schemes of the Boreal, Austral and Central Atlantic realms. Concerning the standard zonation, that corresponds to the zonal scheme of the West Mediterranean province, some changes have been made on two stages. For the Valanginian, the Busnardoites campylotoxus Zone was abandoned; the upper part of the lower Valanginian is now characterised by the Neocomites neocomiensiformis and Karakaschiceras inostranzewi zones. For the upper Barremian, the former Imerites giraudi Zone is here subdivided into two zones, a lower I. giraudi Zone and an upper Martellites sarasini Zone. The I. giraudi Zone is now subdivided into the I. giraudi and Heteroceras emerici subzones, previously considered as horizons. The current M. sarasini and Pseudocrioceras waagenoides subzones correspond to the lower and upper parts of the M. sarasini Zone, respectively. The Anglesites puzosianum Horizon is kept. The Berriasian, Hauterivian, Aptian and Albian zonal schemes have been discussed but no change was made. The upper Hauterivian zonal scheme of the Georgian (Caucasus) region (East Mediterranean province) has been compared with the standard zonation. Discussions and some attempts at correlations are presented here between the standard zonation and the zonal schemes of different
Do the Fama-French Factors Really Proxy for Innovations in Predictive Variables ? by

It has recently been argued that the SMB and HML fa ctors proxy for innovations in predictive variables that characteri ze the investment opportunity set, thereby providing the Fama-French model some theore tical underpinning: an asset pricing model that contains these innovations as ri sk factors would perform better than the Fama-French model, and the innovations in the p redictive variables would make the SMB and HML factors insignificant when introduced i n the cross section of asset returns. We show on the contrary that this result i a these results are statistical artifacts. They are shown to follow directly from arbitrarily making the SMB and HML innovations orthogonal to the return on the market. The Fama-French model in fact performs better than a model containing only the in novations in predictive variables. Moreover, when both are present in the regressions, the variables that tend to be driven out are these innovations, not the Fama-French fact ors. These results are robust to the inclusion of industry portfolios in the investment universe. Therefore, innovations in predictive variables explain at best little of the cross-sectional variation in asset returns. They are also consistent with the view that asset r eturn predictability is present, at best, for investment horizons much longer than a month. Very Preliminary and Incomplete.

Dividends and underinvestment in China: Did foreign investors export liquidity during the global financial crisis?

Little attention has been given to the flow of liquidity internationally between regions with different levels of temporary financial constraints. Examining approximately 18,000 firm-years from China, we find that foreign controlling ownership of Chinese firms was associated with an extraordinary increase in dividend payouts during the 2007–2009 global financial crisis (GFC), with concomitant underinvestment. This evidence is robust to a matched sample of domestically controlled firms selected using propensity-score matching; as well as to an alternative control sample of firms invested by Qualified Foreign Institutional Investors (QFIIs). We interpret our results as not due to a general clientele effect, but suggesting foreign controlling shareholders in China acted specifically to expropriate (export) liquidity through dividends. These findings reveal a principal-principal agency cost
THE DIATOM FRAGILARIOPSIS CYLINDRUS AND ITS POTENTIAL AS AN INDICATOR SPECIES FOR COLD WATER RATHER THAN FOR SEA ICE CECILIE

ANTARCTICA ABSTRACT. – The importance of the diatom Fragilariopsis cylindrus (Grunow) Krieger in Helmcke & Krieger in the Arctic and Antarctic is well known. It is used as an indicator of sea ice when the paleoenvironment is being described. It is often among the dominant taxa in different sea ice communities, sometimes making an important contribution to a subsequent phytoplankton growth when released by ice melt. However, it may also dominate phytoplankton blooms in areas never experiencing sea ice. The use of F. cylindrus as an indicator for reconstruction of palaeoceanographic conditions is assessed from literature records. Its potential as an indicator species for sea ice appears to vary from region to region, but it is a good indicator of cold water.
Real Exchange Rate and Consumption Fluctuations following Trade Liberalization

Two-sector models with traded and non-traded goods have problems accounting for the stylized fact that the real exchange rate appreciates and consumption booms for several years following trade liberalization, or exchange-rate-based stabilization programs, in small open economies. The paper studies three potential solutions to this ‘price-consumption puzzle’ and evaluates their quantitative importance in calibrated simulations of Spain’s accession to the European Community in 1986. Extending the standard two-sector framework, the paper investigates the effects of relative productivity growth in the traded sector along the lines of BalassaSamuelson, of time-to-build, and of habit formation in preferences. In contrast to previous studies, we find that habit formation on its own does not enable the model to account for the observed real exchange rate and consumption dynamics. The analysis shows that a calibrated version of the model augmented with all three mechanisms can account for much of the price-consumption dynamics after trade liberalization, without losing explanatory power for other real variables in the Spanish economy after 1986.

European Countryside MENDELU SLOVENES IN ITALY : A FRAGMENTED MINORITY

The study examines the Slovenian-speaking minority in the northern Italian autonomous region of Friuli-Venezia Giulia. It explores the spatial fragmentation in the Slovenian settlement area in Italy and analyzes the socio-economic and demographic processes that exert influence on the minority. The work is based on the critical evaluation of the current status of research, of statistical data from the state censuses and results of own research on site. The Slovenian-language population in the entire region is currently estimated at about 46,000 people. The main settlement area is the eastern border region of Friuli-Venezia Giulia, which is characterized by different cultural and regional identities. While the Slovenian-speaking population of Friuli focuses more on its cultural and regional distinctions, the majority of the Slovenian-language group in Venezia Giulia considers itself a “national minority. ”
Coupling effects of water and fertilizer on seedling growth and nutrient status of Catalpa bungei

[Objective] Water and fertilizer are two key factors to promote plant growth, thus, it is important to study their coupling effects on growth and nutrient status of Catalpa bungei seedlings. [Method]The pot experiment with Catalpa bungei seedlings in three different water levels (30% ,50% and 70% saturated water content(FWC)) with four fertilization levels of T1(N 0 g,P 0 g,K 0 g), T2(N 2 g,P 1 g,K 1郾 5 g), T3(N 4 g,P 2 g,K 3 g), T4(N 6 g,P 3 g,K 4郾 5 g) was conducted to study the coupling effects of water and fertilizer on growth, nutrient absorption and fertilizer utilization. [Result] The interactive effects of water and fertilizer coupling on morphological indexes of Catalpa bungei 摇 第 2 期 烟亚萍等: 水肥耦合对楸树苗木生长和养分状况的影响 seedlings were not significant. Root collar diameter, height, and biomass of seedlings decreased with rising water level, reaching the top at 30% saturated water content, but firstly increased and then decreased with increasing fertilization level, reaching peak at T3 fertilization level. The nutrient content of seedlings reached a luxury nutrient state at T3 treatment, meanwhile seedling height, root collar diameter, biomass and nutrient content of seedlings were the highest. If more fertilizers were applied on seedlings, it would occur toxic effects. Since at T3 treatment, although the nutrient concentration of seedlings was increasing, the morphological indexes and nutrient content decreased. There were interactions of water and fertilizer coupling effects on nutrient concentration and nutrient content of Catalpa bungei seedlings. Nutrient content rose with increasing fertilizers, and reached the peak under T3 treatment. When water content was 30% FWC, fertilization had a greater promotion for seedlings of Catalpa bungei. [Conclusion] It proves that water and fertilizer coupling effects promote the quality of seedlings. Furthermore, 30% FWC and T3 treatment was the best combination for cultivating seedlings of Catalpa bungei.

Dead on Arrival: An Empirical Study of The Bluetooth 5.1 Positioning System

The recently released Bluetooth 5.1 specification introduces fine-grained positioning capabilities in this wireless technology, which is deemed essential to context-/location-based Internet of Things (IoT) applications. In this paper, we evaluate experimentally, for the first time, the accuracy of a positioning system based on the Angle of Arrival (AoA) mechanism adopted by the Bluetooth standard. We first scrutinize the fidelity of angular detection and then assess the feasibility of using angle information from multiple fixed receivers to determine the position of a device. Our results reveal that angular detection is limited to a restricted range. On the other hand, even in a simple deployment with only two antennas per receiver, the AoA-based positioning technique can achieve sub-meter accuracy; yet attaining localization within a few centimeters remains a difficult endeavor. We then demonstrate that a malicious device may be able to easily alter the truthfulness of the measured AoA, by tampering with the packet structure. To counter this protocol weakness, we propose simple remedies that are missing in the standard, but which can be adopted with little effort by manufacturers, to secure the Bluetooth 5.1 positioning system.
Goals of the present contribution : Various experimental studies of the 11 August 1999 solar eclipse

In the present contribution, we first propose a methodology that enables to detect wave-like structures propagating in ionosphere, by tracking the local maxima of the modulus of continuous complex wavelet transform coefficients with respect to heights. From the derivation of the phases of the wavelet transform, we measure the corresponding propagation parameters. These tools are applied to measurements collected by vertical ionospheric sounding at high-time resolution sampling regime (sampling periods ranged from 1 to 3min) in the observatory Průhonice (49.9N, 14.5E, Czech Republic). The aim of these experiments is to analyze the changes in the ionospheric plasma induced by three different solar eclipse events (total solar eclipses, 11 August 1999, 29 March 2006, and annular solar eclipse, 3 October 2005) and to detect and analyze the propagation of the generated acoustic–gravity waves (AGWs). Second, injecting wave vector components measured from the data into the AGW propagation equations, we obtain a full description of the propagation of the waves. This enables us to differentiate AGWs from others wave-like oscillations and to discuss similarities and differences of the waves detected during these three particular events. These procedures also enabled us to detect acoustic waves. We believe that the methodology proposed here brings significant improvement in detecting and characterizing AGW propagations from empirical data and can be readily used in the ionosphere community. r 2007 Elsevier Ltd.

Analyzing Cultural Sensitivity of Websites

The big question at this stage of global e-commerce evolution is can we afford to be insensitive to the global target markets and if adaptation of websites does make business sense, do we have tools, theories, and frameworks to make websites culturally adapted? The aim of this study is to propose a framework to enhance the cultural adaptability of the web sites. The proposed framework analyzes the cultural content of the web sites at perceptual, behavioral, and symbolic levels.
Relationship between CD 44 high / CD 133 high / CD 117 high cancer stem cells phenotype and Cetuximab and Paclitaxel treatment response in head and neck cancer cell lines

Recent evidence suggests that cancer stem cells (CSCs), a small population of cancer cells that are highly tumourigenic, capable of self-renewal and have the ability to differentiate into cells that constitute the tumor, are the “drivers” of local recurrence and metastatic spread and may be associated with resistant to conventional therapy. The objectives of the study are to identify and characterize two head and neck cancer cell lines with regard CD44high/ CD133high/CD117high profile (CSCs) and CD44low/CD133low/CD117low profile (Non-CSCs); to investigate the influence of chemotherapy treatment in CSCs and compare with Non-CSCs; to evaluate CD44 and EGFR gene expression in CSCs. Fluorescent-activated cell sorting (FACS) using specific cell surface marker combination (CD44, CD117 and CD133) was performed to isolate CSCs of Non-CSCs from cell lines. The Wound Healing assay was performed to confirm the presence of CSCs. After, the CSCs subpopulation and Non-CSCs were cultured and exposed for 24 h to Cetuximab and Paclitaxel treatment, separately. Cell proliferation was determined by MTS assay. CD44 and EGFR gene expression was quantified by quantitative real time PCR (qPCR) using TaqMan® Assay in both subpopulations. CSCs subpopulation untreated were considered as relative expression control. We firstly characterized CSCs in HN13 and HEP-2 cell lines with CD44, CD133 and CD117 biomarkers. We treated CSCs and Non-CSCs subpopulations with Cetuximab and Paclitaxel treatment and found that CSCs subpopulations demonstrated more resistance to Paclitaxel chemoterapy, when compared with Non-CSCs subpopulations of oral cancer cell line. These CSCs subpopulations presented up-regulation of CD44 gene and down-regulation of EGFR gene in oral cancer cell line, and down-regulation of CD44 gene and up-regulation of EGFR gene in laryngeal cancer cell line when compared with Non-CSCs subpopulations. We conclude that the combination of CD44, CD133 and CD117 biomarkers have stem cell properties in both cell lines. CSCs has ability to resist to Paclitaxel treatment in oral cancer cell line. CSCs present high expression of CD44 gene and down expression of EGFR gene in oral cancer cell line. CSCs in laryngeal cell line present down expression of CD44 gene and high expression of EGFR gene when compared with cells without characteristics of cancer stem cells.
Effective teaching styles

Effective teaching style is one of perennial interest in continuing education. The rapidly changing context of continuing education in modern society requires adult educators to continually reassess their teaching practices to meet new needs and situations. The most important skill for teachers ultimately may not be expertise with particular methods as much as it is the ability to engage in a process of critical reflection on the process and outcomes of instruction in relation to the demands of a particular context and an explicit set of values. The chapters in this volume of New Directions for Adult and Continuing Education are intAnded to asist continuing educators in this process of critical reflection. Topics have been selected from a variety of areas important for teachers of adults in a wide range of continuing education programs. This is the 43rd issue of New Directions for Adult and Continuing Education.
TORNADOES ASSOCIATED WITH TROPICAL STORM BERYL

Tropical Storm Beryl significantly affected the eastern United States over the three-day period, 15-17 August 1994. Although n.o tornadoes occurred around the climatologically preferred tzme of landfall on the 15th, an outbreak of 31 tornadoes occurred in the southeast U.S. on the 16th. Nine of the tornadoes were F-Scale 2 or 3, considerably stronger than most tornadoes associated with tropical cyclones. This was the largest tornado outbreak o~ record for a tropical cyclone with peak intensity below hurrzcane strength. Tornado production diminished considerably on the 17th as the system continued north-northeast with only 5 weak tornadoes reported in the mid-Atlantic State~ region. An effort is made in this study to ascertain what parameters contributed to the distinct tornado maximum on 16 August 1994. Results show that a pronounced dry intrusion into the northeast quadrant of the tropical circulation on the 16th destabilized the air mass by creating st~eper lapse rates and enhancing suiface heating. increased instability and stronger stormrelative (SR) helicity on the 16th provided a much more favorable environment for supercell storms compared to the 15th when the system made landfall. It is also hypothesized that dry air in the storm environment increased the potential for tornadoes by enhancing baroclinic generation of vorticity through evaporative cooling in the rear flank downdraft (RFD). The dry intrusion moved offshore on the 17th limiting instability and decreasing the potential for baroclinic generation of lowlevel vorticity along the RFD.
