Genetic characteristics of Fusarium verticillioides isolates from maize in Costa Rica

Thirty-nine isolates of Fusarium verticillioides from maize seeds from three regions of Costa Rica were classified on fertility, fumonisin production, vegetative compatibility and pathogenicity. The identity of the isolates was verified by sexual crosses with standard tester strains and by isozyme analysis. Twenty-three isolates (59%) were mating type A ‐ and 16 (41%) were A ˛ ; 29 (74%) were female fertile. The isolates produced high amounts of fumonisin B1 when grown on sterilized maize grits, 32 isolates producing more than 1000 m gg ‐1 , as determined by TLC, and 7 less than 1000 m gg ‐1 . Vegetative compatibility tests by pairing nit mutants identified 34 vegetative compatibility groups (VCGs), of which 29 had one member and 5 had two members. Isolates belonging to the same VCG were obtained from the same seed sample. Two pathogenicity tests with different inoculation methods were performed: on toothpick inoculation of 7-week-old maize stalks, 71% of the isolates were pathogenic according to the length of the necrosis formed in the stalk, and on sand inoculation of maize seedlings all the isolates were pathogenic, according to shoot length and dry weight production. Differences in aggressiveness between some of the isolates were recorded. It is concluded that natural populations of F. verticillioides in Costa Rica consist of genetically diverse, highly fertile and pathogenic isolates that represent a potential risk for disease development and fumonisin accumulation in maize crops.
SAKE+: Strengthened Symmetric-Key Authenticated Key Exchange with Perfect Forward Secrecy for IoT

Lightweight authenticated key exchange (AKE) protocols based on symmetric-key cryptography is important in securing the Internet of Things (IoT). However, achieving perfect forward secrecy (PFS) is not trivial for AKE based on symmetric-key cryptography, as opposed to AKE based on public-key cryptography. The most recent proposals that provide PFS are SAKE and SAKE-AM. In this paper, we ﬁrst take a closer look at these protocols and observe that they are vulnerable to a number of attacks, such as, replay attack, denial of service (DoS) attack, tracking attack, etc. We then pro-pose countermeasures to both protocols to restore security. Additionally, our proposed scheme SAKE + enables concurrent execution of the protocol, whereas the original SAKE scheme supports the sequential execution of the protocol. The concurrency provided by our scheme makes it more suitable for IoT applications where a server receives and sends information from a large number of IoT end devices. Finally, we prove the security and soundness of our schemes, and verify using ProVerif tool.
The effect of nonlimb tissues on forelimb regeneration in the axolotl, Ambystoma mexicanum

Previous studies with Notophthalmus viridescens have shown that forelimb stumps covered by flank skin do not regenerate when amputated through the graft of nonlimb skin [Tank, P.W. (1984) J. Exp. Zool. , 229:143–153]. In an attempt to determine whether or not cells derived from nonlimb skin dedifferentiate and enter the regeneration blastema, four experimental series were prepared using triploid (3N) marked cells grafted into diploid (2N) hosts of the axolotl (Ambystoma mexicanum). In the first series, head skin was used to replace limb skin followed by amputation through the graft 30 days later. Fully 96% (24/25) of the limbs failed to regenerate an externally visible outgrowth and 4.4% of the blastemal mesenchyme cells were observed to be 3N based on the characteristic of three nucleoli per nucleus. In the second series, flank skin replaced limb skin and 38% (8/21) of the limbs failed to regenerate. The remaining limbs regenerated an assortment of hypomorphic, normal, abnormal, or multiple structures. Only 2.4% of the cells in the blastemal mesenchyme were observed to be 3N in the second series. In the third series, head dermis was implanted in place of limb musculature and 20% (3/15) of the limbs failed to regenerate. The other limbs in series three were either abnormal, hypomorphic, or multiple in morphology. Histological analysis revealed that 3.4% of the cells in the blastemal mesenchyme of the head dermis group were 3N. In the fourth series, flank dermis replaced limb musculature and only 7% (1/15) failed to regenerate. Ten limbs (66%) formed hypomorphic regenerates and the remainder were normal, abnormal, or multiple in morphology. Histological analysis revealed that 6.8% of the cells were 3N in the blastemal mesenchyme of limbs in series four. Sham-operated controls for all four series regenerated normally and histological analysis of contralateral control limb regenerates revealed background 3N marker that averaged from 0.1 to 0.8%. The regenerate epidermis of limbs that were covered by 3N head skin or flank skin contained approximately 25% 3N cells, indicating that the epidermis was of nonlimb origin. The regenerate epidermis of limbs bearing 3N dermis implants did not contain marked cells. These results indicate that non-limb cells are capable of undergoing dedifferentiation and entering the limb regeneration blastema. An explanation of regenerative failure is provided that is based on interference with short range cellular interactions by nonlimb cells.
BIROn - Birkbeck Institutional Research Online

This paper addresses the place of exiles and refugees in the Greek poleis (city-states), with a focus on the later Classical and Hellenistic periods (c. 400–100 BC). It examines the different forms of protection and aid granted by Greek poleis and their citizens to people displaced through war and civil strife. Its main focus is the range of arguments and ideals advanced by ancient Greeks as grounds for granting these forms of protection and aid to exiles and refugees. Displaced Greeks and their hosts could, for example, present aid to displaced groups as guided or inspired by justice, law, freedom and shared Greek identity. Alternatively, in a move which became increasingly prominent in formal political contexts in the period considered here, they could present help to the displaced principally as a matter of respecting unconditional ethical ties binding together all humans, or all ‘citizens of the world’. This paper argues that the diverse range of relevant Greek practices and values both reflected and helped to shape complex and shifting ancient Greek ideas about the city, citizenship, democracy, justice, freedom, virtue and gender. Throughout its argument, the paper draws connections and contrasts between ancient Greek and modern liberal practices and ideology, and their underpinnings in broader ethical and political ideals. Modern liberal practices and values concerning aid to refugees draw on, and combine, the approaches and traditions evident in the ancient Greek world, as well as diverging from them in revealing ways.
CSR in India: A Study of Hospitality Industry

Organizations have a lot to think about to bring this new field into play. They need to strategize their profit distribution to be in sync with social awareness and participation. Once just a jargon, corporate image is a common phrase that refers to a company’s reputation. This reputation is what the public perceives and bases its decision on. A ‘good’ corporate image ensures a good asset, much like the dollars one gets on selling shares at a very high valuation. The aim of this study is to understand the impact of Corporate Social Responsibility in the Hospitality Industry on Employee Engagement, Organizational Performance, Brand Image and Ethics and Corporate Governance. Three sectors of the hospitality industry – hotels, hospitals, and airlines, were studied with the help of managers working in select companies that operate under each sector to analyze the impact of CSR from a managerial perspective. The aim was to find out the correlation existing between the dependent and independent factors. From the data analysis, suitable conclusions are drawn. The findings of the research can further be extended to future prospects for further analyse as the subject of CSR in hospitality is fairly new.

Multifunctionality of Iran's agriculture: a researchers' perspective.

The main purpose of this descriptive enquiry was to investigate Kermanshah’s agricultural researchers’ opinions towards multifunctionality of Iran’s agriculture. Multifunctionality as a term was invented to sum up diverse aspects of agriculture in an attempt to be systemic and prevent potential conflicts and damages caused by reductionist interventions in this area. A total of 105 researchers were selected through a process of stratified random sampling and its face- and content validity was established by a panel of experts. Reliability of the instrument was calculated using Cronbach's alpha and proved to be at 0.88. Data were collected and analyzed by SPSS software. Generally speaking, production was emphasized on to be currently the most important functionality of Iran’s agriculture, far greater than environmental or even cultural issues, according to researchers’ opinions.
Habitat selection in a changing environment: the relationship between habitat alteration and Scops Owl (Aves: Strigidae) territory occupancy

Abstract The Scops Owl Otus scops (L., 1758) is a species of European concern, which suffered a noticeable decrease in distribution in the last decades, and changes in agricultural practices have been proposed as a major threat for this owl. We studied the habitat preference of the Scops Owl by assessing the habitat occupancy of 401 territories distributed in a large area in northwest Italy, with a special focus on 98 territories located in a high-density area (Monferrato). Habitat characteristics were analyzed with maximum entropy (MAXENT) models that included both vegetational (16 land use categories) and physical features estimated from a Digital Terrain Model (DTM) (altitude, slope, hillshade). In the Monferrato area, a comparison of 2009 landcover was also made with year 1954/55 characteristics obtained from aerial photographs. In the full northwest Italy area, the Scops Owl preferred areas located at middle altitude with intermediate slope. The preferred habitats included riparian areas and pasture-grassland, while woodlands and zones with Robinia pseudoacacia shrublands were avoided. In the Monferrato area, Scops Owl occupancy occurred in sites where the landuse (croplands/vineyard mosaic) had changed little since the mid-1950s. Our study suggests that conservation activity should focus on interventions halting riparian zone transformation and subsidies promoting agricultural practices favouring pastures and grassland.
APPLICATION OF CLUSTERING BY FAST SEARCH AND FIND OF DENSITY PEAKS TO BEAM DIAGNOSTICS AT SSRF*

With the increased technological complexity of accelerators, meeting the demand of beam diagnostics and operation need more powerful and faster methods. And detecting the accuracy and stability of beam position monitors(BPMs) are important for all kinds of measurement systems and feedback systems in particle accelerator field. As an effective tool for data analysis and automation, the machine learning methods had been used in accelerator physics field, recently. Among machine learning methods, the clustering by fast search and find of density peaks as a typical unsupervised learning algorithms could be performed directly without training in arbitrary accelerator systems and could discover unknown patterns in the data. This paper used clustering by fast search and find of density peaks to detect faulty beam position monitor or monitoring beam orbit stability by analysis five typical parameters, that is beta oscillation of X and Y direction (BetaX and BetaY), transverse oscillation of X and Y direction(AmpX and AmpY) and energy oscillation(AmpE). The results showed that clustering by fast search and find of density peaks could classify beam data into different clusters on the basis of their similarity. And that, aberrant run data points could be detected by decision graph. Morever, analysis re-sults demonstrate the characteristic parameters AmpE, AmpX and BetaX amplitude have the same effect to distinguish the faulty BPMs and the AmpY and the BetaY amplitude are also.
DIRECT STRENGTH PREDICTION OF LIPPED CHANNEL COLUMNS EXPERIENCING LOCAL-PLATE/DISTORTIONAL INTERACTION

ABSTRACT: This paper reports an ongoing investigation intended to assess the performance of the Direct Strength Method (DSM) to estimate the ultimate strength of lipped channel columns affected by local-plate/distortional mode interaction. First, the DSM approaches to safety check columns against local-plate and distortional failures are briefly reviewed, with special attention devoted to a recently proposed extension that takes into account the above buckling mode interaction. Next, one presents and discusses the results of a parametric study, carried out by means of the code ABAQUS and involving the evaluation of the “exact” ultimate loads of 63 lipped channel columns with various geometries, all exhibiting local-plate/distortional interaction. Then, these ultimate strength data are compared with the estimates provided by the available DSM formulae and, on the basis of this comparison, one identifies several features that a DSM approach successfully accounting for local-plate/distortional interaction must incorporate.
A New Species of Moranopteris (Polypodiaceae) from Inaccessible Ledges in the High Andes of Peru.

Abstract Moranopteris inaccessa, here described and illustrated, is a new species from southern Peru. Plants were collected in the Abra Málaga private conservation area from steep ledges accessible only with mountaineering equipment. Moranopteris inaccessa differs from its congeners by the combination of elongate membranaceous laminae that are 1-pinnate-pinnatifid. Found at 4,427 m, its distribution is over 500 m higher in elevation than any other species of Moranopteris. Phylogenetic analyses of atpß, rbcL, and trnL-trnF molecular sequences, using maximum parsimony, maximum likelihood, and Bayesian analysis support M. inaccessa as sister to M. longisetosa. The two are similar in their elongate and highly divided leaves compared to other species of Moranopteris. The discovery of this new species highlights the value of undertaking botanical surveys of undisturbed vegetation patches in the high Andes that potentially host unrecognized plant diversity.
A Novel TRE Framework Based Cloud Bandwidth and Cost Reduction System

Cloud is changing our life by giving clients new sorts of administrations. a novel end-to-end movement repetition disposal (TRE) framework, intended for distributed computing clients. Cloud-based TRE needs to apply a wise utilization of cloud assets so that the transfer speed expense decrease consolidated with the extra cost of TRE. Be that as it may, for server particular TRE methodology it's hard to handle the activity proficiently and it doesn't suites for the cloud setting because of high process costs. Amid this paper we give a study on the new movement excess procedure called novel-TRE conjointly called collector based TRE. This novel-TRE has vital choices like criminologist work the repetition at the client, arbitrarily pivoting seem anchored, matches approaching pieces with a prior got lump chain or local record and sending to the server for anticipating the long run data and no would like of server to persistently keep up buyer state.
A Novel Pragmatic RRW Framework to Resist on Unintentional Attacks

Robust reversible watermarking (RVW) is used to protect the copyright and providing robustness against unintentional attacks. In the past histogram rotation-based method suffers from extremely poor invisibility for watermarked images and limited robustness in extracting watermarks from the watermarked images destroyed by different unintentional attacks. In this paper proposed wavelet-domain statistical quantity histogram shifting and clustering (WSQH-SC) method and enhanced pixel-wise masking (EPWM). This method embedded a new watermark image and extraction procedures by histogram shifting and clustering, which are important for improving robustness and reducing run-time complexity. It is possible reversibility and invisibility. The experimental result shows that the comprehensive performance in terms of reversibility, robustness, invisibility, capacity and run-time complexity and widely applicable to different kinds of images.
Perceived Roles of Bhutanese Health Care Professionals in Improving Patient Safety: A Qualitative Exploratory Descriptive Study

Background and Objectives: Patient safety is a vital component of high quality health care and all health care professionals have a responsibility for ensuring the delivery of safe care to patients. However, little is known about how Bhutanese health care professionals perceive their roles in improving patient safety. This study aimed to explore how Bhutanese health care professionals, educators, managers, and policy makers perceived their roles in improving patient safety. Methods: Undertaken as a naturalistic inquiry using a qualitative exploratory descriptive research approach, a criterion-based stratified purposive sample of 94 health care professionals and managers from the Ministry of Health, a training institute, and 3 levels of hospitals were interviewed. All interview data were analyzed using content and thematic analysis strategies. Results: Data analysis identified 4 broad themes. Health care professionals' perceived role in safety and quality included formulating and implementing patient safety rules; management and administration of units and hospitals; patient assessment and management; and setting professional norms (including norms about peer influence and patient care/interaction). Conclusion: The findings revealed that Bhutanese health care professionals were aware of their roles in improving patient safety processes and practices, and providing interprofessional education or training to all levels of health care professionals could help improve communication and patient safety in the Bhutanese health care system.
Including non-additive eects in Bayesian methods for the prediction of genetic values from genome-wide SNP data

It is a challenging task to predict the genetic values for traits in dairy cattle on the basis of genome-wide SNP markers. Methods including additive genetic effects have already been studied, but the importance of non-additive effects for the genetic variation is not fully understood. From the biological perspective it is especially of interest to know which loci interact. Furthermore, a better prediction of genetic values is intended, when additive effects, dominance and pairwise epistatic effects are jointly involved in fitting a model to a trait. In order to avoid the estimation of additional covariance components, the genotypic effects have to be appropriately re-parameterised in advance. Three methods of orthogonalisation, which are proposed in the literature, are applied to simulated datasets. Different scenarios are simulated and analysed to verify whether the non-additive effects are precisely estimated.
Quantitative genetic bases of anthocyanin variation in grape (Vitis vinifera L. ssp sativa) berry: a QTL to QTN integrated study

28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 The combination of QTL mapping studies on synthetic lines and association mapping studies on natural diversity represents an opportunity to throw light on the geneticallybased variation of quantitative traits. With the positional information provided through QTL mapping, which often leads to wide intervals encompassing numerous genes, it is now easily feasible to directly target candidate genes that are likely to be responsible for the observed variation in completely sequenced genomes and test their effects through association genetics. This approach was performed in grape, a newly sequenced genome, in order to decipher the genetic architecture of anthocyanin content. Grapes may either be white or colored, ranging from the lightest pink to the darkest purple tones according to the amount of anthocyanin accumulated in the berry skin, which is a crucial trait for both wine quality and human nutrition. Although the determinism of the white phenotype has been fully identified, the genetic bases of the quantitative variation of anthocyanin content in berry skin remain unclear. A single QTL responsible for up to 62% of the variation in the anthocyanin content was mapped on a Syrah x Grenache F1 pseudo-testcross. Among the 68 unigenes identified in the grape genome within the QTL interval, a cluster of four Myb-type genes was selected based on physiological evidences (VvMybA1, VvMybA2, VvMybA3, and VvMybA4). On a core collection of natural resources (141 individuals), 32 polymorphisms revealed significant association, and extended LD was observed. Using a multivariate regression method, we demonstrated that five polymorphisms in VvMybA genes except VvMybA4 (one retrotransposon, 3 SNPs and one 2bp Indel) accounted for 84% of the observed variation. All these polymorphisms either led to structural changes in the MYB proteins
Isolation and characterization of lactic acid bacteria from romanian fermented vegetables

Fermentation was used since ancient times as an easy method of vegetables' preservation, which also maintains and/or improves the nutritional and sensory properties of vegetables. The spontaneous fermentation process is mainly carried out by lactic acid bacteria (LAB). The aim of our study was to isolate and characterize the LAB involved in such spontaneous fermentations. Brine and vegetable samples were collected from 20 fermentations carried out at household level. They were analysed for acidification and plated on VRBG agar medium (for enumeration of enterobacteriaceae) and MRS agar medium (for enumeration and isolation of LAB). The cell morphology, growth at different temperatures, capsular polysaccharide production, mucoidness and ropyness of the colonies for the Gram-positive, catalase-negative isolates (139) were investigated. LAB were prevalent in all end-samples, as represented by their MRS counts, whereas enterobacterial counts were low in most cases, indicating good fermentation quality. All isolates grew well at 37oC and 45oC, in only 24h, while the growth at 10oC was slower for some of them (72h). The cells are rod-shaped for most of the isolates, while the others are cocci and coccobacilli. All except five isolates were shown to produce capsular polysaccharide and 31 developed mucoid colonies on sucrose-based media.
