It is a biblical faith position that followers of the Christ should give away the bread they bake freely (Ecclesiastes 11:1-16, Matthew 5:38-42), rather than try to force your neighbour to accept it. Maybe the others only eat cake, or hard-boiled arguments. If the neighbours, however, need and ask for nutritious bread, we rich Christians are called by God to provide wholesome food for thought as well as bellies, says Scripture, with a gentleness, respect for the stranger, and with a sound, self-critical consciousness that may involve our getting hurt ourselves (I Peter 3:13-17).

Full textAbstract:
The centrality of the Shema in Jewish faith and life serves as a rich case study for Christian liturgical theology. The role and significance of the Shema in Jewish daily prayer, liturgy and performative ritualization points to dimensions of worship in which text and action, liturgy and life, prayer and politics, converge. Liturgical, historical, performative, biblical and theological aspects of the Shema are interpreted in relation to Paul Tillich’s notion of “ultimate concern” and Walter Brueggemann’s exegesis of “God-neighbour” to advance a more holistic Christian lex orandi.

Full textAbstract:
In this study, the genetic diversity and relationships among eight millet genera were investigated by molecular and morphological data analyses. Sixty-nine millet accessions were analysed by using amplified fragment length polymorphism (AFLP) markers, and evaluated for morphological traits. Eight AFLP primer pairs were amplified successfully and 779 bands were scored for all accessions, with a high level of polymorphism detected. Nei’s genetic distance among all accessions varied from 0.0123 to 0.4246 and the Shannon’s index was estimated at 0.9708. The neighbour joining tree, using the unweighted neighbour-joining method and Dice’s dissimilarity coefficient, was constructed. The AFLP markers revealed the close relatedness between the Eragrostis and Panicum genera, whereas the greatest distance was found the Pennisetum and Echinochloa genera. Cluster analysis based on the AFLP profiles revealed that the majority of accessions of a given millet genus tend to group together. Clustering from morphological data allocated individuals into three main clusters with high variation. The genetic variability found between the analysed accessions was weakly negatively correlated (r = –0.074) with their morphological attributes. However, high molecular and morphological variability indicated that this collection includes rich and valuable plant materials for millet breeding.

Full textAbstract:
AbstractThe coupled thermal oxidation and deprotonation in air of iron-rich biotite (FeO + Fe2O3 = 34%) has been investigated by EXAFS and XANES spectroscopy at the Fe-K edge and by XANES spectroscopy at the Ti-K edge. Samples annealed for 5 h at temperatures between 250° to 600°C have been studied. Distortions mainly of the Fe-Fe correlation within the octahedral layers are reflected in increasing Debye-Waller factors of the Fe-Fe correlation peak proportional to the annealing temperature. Unchanged Fe-O nearest-neighbour and Fe-Fe next-nearest-neighbour coordination numbers show that these distortions, nonetheless, do not change the structural topology of the octahedral layers. A model is introduced to demonstrate that increasing distortions are compatible with the expected heterogenous deprotonation mechanism in biotite. Titanium occurs in octahedral coordination. It was found to be unaffected by the coupled oxidation/deprotonation process. Both the coordination number and the valence state stay constant during the annealing process, in spite of dramatic changes of the Fe2+/Fe3+ ratio. Thermally activated hopping conduction involving Ti according to Fe2+Ti4+ → Fe3+Ti3+ is, therefore, not a significant process during thermal deprotonation and oxidation in biotite.

Full textAbstract:
AbstractUsing microsatellite markers, the genetic structure of nine domestic duck (Anas platyrhynchos) populations in eastern China was analysed. The results showed that the heterozygosity was high in these populations, ranging from 0.5137 to 0.6055, with an average heterozygosity of 0.5523, reflecting the rich diversity. Considerable breed differentiation was observed and 25.65% of the total genetic variation came from breed differences; this low differentiation result affirmed that each breed has its own genetic diversity. The DA genetic distances suggested that greater differentiation existed between populations. The duck populations were clustered into four groups based on neighbour joining (NJ) clustering, and the clustering results showed relationships with duck breed distributions and economic utilization.

Full textAbstract:
ABSTRACT We study the relation between the properties of the bulge/disc components and the H i mass fraction of galaxies. We find that at fixed stellar mass, disc colours are correlated with the H i mass fraction, while bulge colours are not. The lack of a correlation between the bulge colour and the H i mass fraction is regardless whether the bulges are pseudo, or whether the galaxies host bars or are interacting with a neighbour. There is no strong correlation between the colours of the discs and bulges either. These results suggest that the current total amount of H i is closely related to the formation of discs, but does not necessarily fuel the formation of (pseudo) bulges in an efficient way. We do not find evidence for the star formation in the discs to be quenched by the bulges.

In 1986 Howard Barker abridged Thomas Middleton's tragedy Women Beware Women and wrote a new ending. This version was published and staged as a collaboration between the Jacobean and the modern playwright. There are a number of differences, but also points of connection between Barker's version and Middleton's Jacobean tragedy. Middleton sets out a moral fable on the corrupting nature of desire and greed. Leantio, a clerk, falls in love with Bianca, a rich man's daughter. They elope and live in secrecy with Leantio's mother. Despite her husband's exhortations to keep herself private, Bianca is spotted by the Duke of Florence, who determines to make her his. A wealthy neighbour, the widow, Livia, aids him in this, luring Bianca and the mother to her house where Bianca is raped by the Duke. Bianca's story is mirrored by that of Isabella, who is being ‘sold’ into marriage with a rich fool and is tricked into an incestuous relationship with her uncle Hippolito. Bianca leaves her husband to become the Duke's mistress. Leantio is taken up by Livia.

This paper investigates the trade growth nexus in landlocked developing countries. Landlockedness imposes exogenous costs to a country making import more expensive and exports uncompetitive. Despite this fact, landlocked countries also are in the process to be integrated with world but in slow pace. Initial income is one of the major determinants of economic growth in these countries whether they are poor or rich now, however, negative impact of Landlockedness seems more severe in economic growth of poor countries. Trade has a positive role in landlocked countries too to trade than the poor countries. Neighbour countries’ economic growth has level increases, it shifts towards industrialisation so that capital formation is more important compared to labour force until the economy converges to the developed economy.

America is the richest country in the world. And yet tonight, thousands of your neighbours will go to bed hungry. It may be your child's schoolmate who is undernourished and has difficulty learning on an empty stomach. Or it could be a co-worker, a working mother whose low-wage job doesn't make ends meet. Perhaps it's an elderly neighbour who has to make a decision whether to delay filling a prescription or buying groceries. The faces of hunger are as broad as the faces of America- David Nasby, General Mills Over 1.2 billion people - one in every five on Earth - live on less than $1 (U.S)a day. We're getting fatter and fatter in America, as well as in most of the rest of the world. Of course there are some starving people who don't have enough to eat or to sustain themselves, and this is a serious problem that should be addressed. Poverty does not have one clear definition. It is a complicated, multi-faceted concept. For this paper the term 'poverty' will be used to mean a lack of access to basic resources including food, clean water, sanitation, education and capital. Indeed, hunger is the worst manifestation of poverty and it will persist as long as poverty exists but Are people only hungry for food? No!. People are hungry everywhere, some for money, some for property, some for lust, some for love, some for power. As long as there is a desire for more and more, hunger cannot be eradicated. Hunger for food is fatal but equally debatable issue as other hungers of world. You give food to poor because they are hungry, they will be more hungry for better food then. Hunger is immortal but poverty can be murdered. The world has made great strides in the struggle against poverty, but we're a long way from realizing the benchmark of the Millennium Development Goals to cut in half by 2015 the proportion of people who suffer poverty. Growing population is not the cause of poverty, money is enough in the world infact more than it would have been but it is the distribution which is flawed. Richer getting richer and poorer getting poorer, it is not the mistake of poor or the luck of richer but the system itself which was created to make such difference whether it is brettonwoods conference or Americas plan to capture oil contented nations. The aim of this paper will be to prove, it is poverty alone which can be eradicated from the world by different mechanisms and policies for which every country should stand and deliver its part but not the hunger of desire to have more and more.

Abstract. Precise point cloud classification can enhance lidar performance in various applications, such as land cover mapping, forestry management and autonomous driving. The development of multispectral lidar improves classification performance with rich spectral information. However, the employment of spectral information for classification is still underdeveloped. Therefore, we proposed a spectrally improved classification method for multispectral LiDAR. We conducted spectral improvement in two aspects: (1) we improved the eigenentropy-based neighbourhood selection by spectral angle match (SAM) to reform the more reliable neighbour; (2) we utilized both geometric and spectral features and compare the contributions of these features. A three-wavelength multispectral lidar and a complex indoor experimental scene were used for demonstration. The results indicate the effectiveness of our proposed spectrally improved method and the promising potential of spectral information on lidar classification.

AbstractSeafood consumption is highly demanding due to the important source of protein it contains, as well as being rich in omega-3 fatty acids. However, the adulteration of seafood is an alarming issue worldwide, including India. This study deals with edible crabs from seafood shops on the Odisha state coast in eastern India. The generated DNA barcode sequences successfully identified most of the studied brachyuran crab species by similarity search results in global databases. The species were also delimited by significant genetic divergence and Neighbour-Joining phylogeny. Additionally, the study detected the contamination of unknown organisms in the commercialized crab recipes from seafood shops. The DNA based species detection of brachyuran crab may be useful to resolve many ambiguities in species identification and monitoring of commercialized seafood concerning food safety.

Full textAbstract:
The Category of Neighbourhood in Islamic Modernism of Yugoslavia. "Fetve" of Husein ĐozoDeparting from Carl Schmitt’s assertion that all significant concepts of modern theory of the state are secularized theological concepts, the article tries to recreate the political and ethical theory of the neighbour present in the Qur’ānic commentaries and fatwās (fatāwā) of Husein Đozo as the main representative of Islamic Modernism in former Yugoslavia. Subsequently it seeks to establish connection between the theoretical framework od theological dogmas, and the everyday praxis preserved in the formula of fatwā as a genre of religious Islamic literature which by giving answers to the questions of the faithful Muslims, forms a dialogue of authority and the society, of the theory and the praxis.Using the tools of Critical Discourse Analysis the text extracts the categories of neighbourhood and reveals that they are mainly faith-based. In other words, in the common perception, members of various religious communities: Muslims, Jews, Christians are each other’s neighbours. According to the analysed exegetical and juridical Islamic sources, the neighbourhood category is based on freedom and mutual respect and can be shared by Muslims, atheists and apostates from Islam to atheism.In consequence the text shows that the non-trespassable border of an inherent to each of the neighbour units culture, forms a central neighbourhood-defining category. It is precisely the maintenance of dissimilarities between the neighbours that safeguards tolerance, respect and freedom for the members of particular entities. The internal systems of signs, behaviours, artefacts and lifestyles sustain the preservation of equality between the neighbours, as long as they share the same social capital and thus, retain the symmetrical positionality towards each other.Taking up a position of distance from the common lifestyle values (like in the case of Roma Muslims), or from intellectual legacy of Semitic Abrahamic faiths (like in the case of Baha’i faith which incorporates such figures as Krishna and Buddha), results in exclusion from the category of neighbourhood. Thus, the spatial and social proximity forms the core of neighbourhood classification.The paper is based on rich exemplification of fatwas that reveal the absorption of Judeo-Christian heritage into the Islamic thought, and explains the theoretical and theological framework of this process. It presents the perception of neighbour and neighbourhood in the Islam of socialist Yugoslavia, and – to some extent – the intellectual outcome of Judeo-Christian and Islamic neighbourhood in terms of spatial and theological vicinity.Finally, the article shows that the Yugoslav Islamic stance towards the once classified neighbour is inclusive, welcoming and hospitable. Intellectual background of this attitude is formed by the tradition of Islamic Modernism of early 20th century Egypt, and the influence of such Islamic thinkers as Jamāl ad-Dīn al-Afghānī, Muḥammad ‘Abduh, Muḥammad Rašīd Riḍā, Maḥmūd Šaltūt. Hence, the article implicitly poses a question on the intellectual origins of the Islamic openness towards the neighbour, inherent to Titoist Bosnia. Kategoria sąsiedztwa w islamskim modernizmie w Jugosławii."Fetve" Huseina ĐozoWychodząc od twierdzenia Carla Schmitta, że wszystkie znaczące pojęcia współczesnej teorii państwa to zsekularyzowane pojęcia teologiczne, autor próbuje odtworzyć polityczną i etyczną teorię sąsiedztwa, obecną w koranicznych komentarzach i fatwach (fatāwā) Huseina Đozo, głównego przedstawiciela modernizmu islamskiego w byłej Jugosławii. Równocześnie stara się ustanowić relację między teoretycznymi ramami dogmatów teologicznych a codzienną praktyką, zachowaną w formule fatwy jako gatunku religijnej literatury islamskiej, która poprzez odpowiedzi na pytania wiernych muzułmanów tworzy dialog o władzy i społeczeństwie, teorii i praktyce. Zastosowano narzędzia krytycznej analizy dyskursu fragmentów tekstów dotyczących kategorii sąsiedztwa, pokazując, że teksty te są głównie oparte na wierze. Innymi słowy, w potocznej percepcji członkowie różnych wspólnot wyznaniowych, muzułmanie, żydzi i chrześcijanie, są sąsiadami. W myśl egzegetycznej i prawnej analizy źródeł islamskich kategoria sąsiedztwa opiera się na wolności i wzajemnym szacunku oraz może być dzielona przez muzułmanów, ateistów i konwertytów z islamu na ateizm.W konsekwencji tekst pokazuje, że nieprzekraczalna granica nieodłącznie wpisana w każdą sąsiedzką jednostkę kulturową tworzy centralną kategorię definiującą sąsiedztwo. To właśnie zachowanie różnic między sąsiadami chroni tolerancję, szacunek i wolność członków poszczególnych jednostek. Wewnętrzny system znaków, zachowań, artefaktów i stylów życia wspiera zachowanie równości między sąsiadami, dopóki dzielą ten sam kapitał społeczny a przez to utrzymują symetryczną pozycję wobec siebie.Tekst opiera się na licznych przykładach fatw odkrywających przyswajanie dziedzictwa judeochrześcijańskiego przez myśl islamu oraz wyjaśnia teoretyczne i teologiczne ramy tego procesu. Przedstawia także postrzeganie sąsiada oraz sąsiedztwa w islamie w socjalistycznej Jugosławii, a do pewnego stopnia również intelektualny wymiar judeochrześcijańskiego i islamskiego sąsiedztwa jako przestrzennej i teologicznej bliskości. Artykuł pokazuje, że stanowisko w jugosłowiańskim islamie wobec sąsiada ma charakter inkluzywny, otwarty i zapraszający. Intelektualne podłoże takiej postawy tworzy tradycja modernizmu islamskiego formującego się we wczesnych latach XX w. w Egipcie oraz wpływ takich islamskich myślicieli, jak Jamāl ad-Dīn al-Afghānī, Muḥammad ‘Abduh, Muḥammad Rašīd Riḍā, Maḥmūd Šaltūt. W ten sposób artykuł stawia też pytanie o intelektualne źródła islamskiej otwartości na sąsiada, nieodłączne dla Titowskiej Bośni.

We present here the first large-scale genetic characterization of grape cultivars from Transcaucasia and Anatolia. These regions where wild grapes still grow in nature have been cultivating wine and table grapes for thousands of years and are considered the cradles of viticulture. Using 12 nuclear microsatellite markers, we genotyped 116 accessions of traditional grape cultivars from Armenia, Georgia and Turkey and we detected 17 identical genotypes and six homonymy cases, mainly within each national germplasm. Neighbour-joining analysis of genetic distance showed that each germplasm could have multiple origins and although they are now separated, they might have some common ancestors. In addition, four varieties from Western Europe included as outgroups turned out to be more related to Georgian cultivars than other germplasms, suggesting a possible ancient origin in Georgia. This work represents a first step towards germplasm management of this rich ampelographic heritage.

Full textAbstract:
AbstractFruit flies (Diptera: Tephritidae) are a species-rich and economically important group. The phylogenetic relationships among the many taxa are still to be fully resolved and the monophyly of several groups is still to be confirmed. This paper reports a study of the phylogenetic relationships among 23 economically important tephritid species (representing several major lineages of the family) which examines the sequence of a region of mitochondrial DNA encompassing the cytb, tRNASer and ND1 genes. Substitutions characteristic of particular taxa were found that could help classify members of the family at any developmental stage. The trees obtained by the maximum parsimony, neighbour joining and maximum likelihood methods were generally compatible with present morphological classification patterns. However, the data reveal some characteristics of the phylogenetic relationships of this family that do not agree with present classifications. The results support the probable non-monophyletic nature of the subfamily Trypetinae and suggest that Bactrocera cucurbitae (Coquillet) is more closely related to the genus Dacus than to other species of Bactrocera.

Full textAbstract:
The binary cyanide, Cu(CN)2, has never been synthesised. However, by using Ni(CN)42-as a structural synthon, copper(II) can be stabilised in a cyanide-only environment in CuNi(CN)4and in the solid-solution CuxNi1+x(CN)2(0 ≤ x < 1/4). The atomic structure of the layers in CuNi(CN)4and the stacking relationship between nearest-neighbour layers have been determined from total neutron diffraction studies at 10 and 300 K. The structure consists of flat layers of square-planar, ordered [Ni(CN)4] and [Cu(NC)4] units. (NB it is very unusual to find Cu(II) in a genuine square-planar environment within an extended solid). The layered structure of this new material is closely related to those of the Group 10 cyanides, Ni(CN)2, Pd(CN)2.xNH3and Pt(CN)2.xH2O, except that these are generated from vertex-sharing square-planar metal-cyanide units with head-to-tail disorder of the C≡N groups. The overall appearance of the powder X-ray diffraction pattern of CuNi(CN)4, including the unusual peak shapes of the observed Bragg reflections, has been successfully explained using models incorporating stacking disorder between next nearest neighbour layers. CuNi(CN)4forms less extended sheets than Ni(CN)2[1, 2], but larger sheets than those found in Pd(CN)2.xNH3and Pt(CN)2.xH2O, which are nanocrystalline [3]. CuNi(CN)4, like Ni(CN)2[1], shows interesting thermal expansion behavior i.e. intralayer negative thermal expansion (αa = -9.7 MK-1) and interlayer positive thermal expansion (αc = +89 MK-1). CuNi(CN)4forms as an anhydrous material from aqueous solution, unlike Ni(CN)2, which can form hydrates such as Ni(CN)2.nH2O (n = 3, 3/2, 2, 1). However, on investigating the Cu-Ni-CN phase diagram, it is found that nickel-rich compounds, CuxNi1+x(CN)2(0 ≤ x < 1/4), can be formed via hydrated phases, CuxNi1+x(CN)2.3H2O, and readily rehydrate. Attempts to form copper-rich phases results in partial reduction of Cu(II) with the formation of copper(I) cyanide, CuCN, in addition to CuNi(CN)4, suggesting that Cu(II) ions are stable in a cyanide environment only when connected to the nitrogen ends of bridging C≡N ligands. Hence the non existence of Cu(CN)2can now be explained.

Full textAbstract:
In the era of large-scale Galactic astronomy and multi-object spectroscopic stellar surveys, the sample sizes and the number of available stellar chemical abundances have reached dimensions in which it has become difficult to process all the available information in an effective manner. In this paper we demonstrate the use of a dimensionality-reduction technique (t-distributed stochastic neighbour embedding; t-SNE) for analysing the stellar abundance-space distribution. While the non-parametric non-linear behaviour of this technique makes it difficult to estimate the significance of any abundance-space substructure found, we show that our results depend little on parameter choices and are robust to abundance errors. By reanalysing the high-resolution high-signal-to-noise solar-neighbourhood HARPS-GTO sample with t-SNE, we find clearer chemical separations of the high- and low-[α/Fe] disc sequences, hints for multiple populations in the high-[α/Fe] population, and indications that the chemical evolution of the high-[α/Fe] metal-rich stars is connected with the super-metal-rich stars. We also identify a number of chemically peculiar stars, among them a high-confidence s-process-enhanced abundance-ratio pair (HD 91345/HD 126681) with very similar ages and v X and v Y velocities, which we suggest have a common birth origin, possibly a dwarf galaxy. Our results demonstrate the potential of abundance-space t-SNE and similar methods for chemical-tagging studies with large spectroscopic surveys.

Full textAbstract:
Larvae of many-plumed moths (Alucitidae), especially in the world-wide genus Alucita Linnaeus, 1758 are known as borers or gall-inducers on flowers, fruits and shoots of a few dicotyledonous families, including Bignoniaceae, Caprifoliaceae and Rubiaceae. However, there is no study available on the biology of the monotypic, Neotropical genus Prymnotomis Meyrick, 1931 except for its original description that was based on a single male, the holotype of Prymnotomis crypsicroca Meyrick, 1931 from Espirito Santo, Brazil. We describe here a second species for this genus, Prymnotomis cecidicolasp. nov. whose larvae induce galls on Cordiera elliptica (Cham.) Kuntze (Rubiaceae), a dioecious plant with dimorphic inflorescences found in the Brazilian Cerrado, Planaltina City, Federal District. Adults, larvae, pupae and galls are illustrated under light and scanning electron microscopy. Galls are green, spherical, unilocular and develop individually on C. elliptica flower buds. During development they look like fruits in shape and colour but are larger, do not have style scars when on female plants, and are induced also in male inflorescences. Pupation occurs outside the gall within a silk cocoon, presumably in the litter. A preliminary analysis of DNA barcode sequences including putative members of other alucitid lineages and Neotropical BINs (Barcode Index Number) supports Prymnotomis cecidicolasp. nov. as an independent phylogenetic unit, with 12 to 18% divergence.

Full textAbstract:
The City of London Poor Law Union in the early to mid-Victorian period was the richest and least populated of all the metropolitan Poor Law districts. A wide range of parochial, livery, and other charities within the City not only attracted vast numbers of applicants for assistance, but influenced the quality and nature of the care given by the local union. This not only meant that provision for the outdoor poor, children, and the elderly tended to be more liberal than elsewhere in the capital, but that vagrants, many of whom took up winter residence in the City, also experienced a higher standard of pauper treatment than that offered by the surrounding unions. The combination of high Poor Law receipts from a low poor rate base, civic pride, competition from City charities, and the willingness of neighbouring unions to off-load this most troublesome class of pauper on to their rich neighbour gave an unparalleled level of choice to those who were truly at the bottom of the heap in Victorian London.

Full textAbstract:
The strong dynamics of magnetic correlations are observed by high field 57Fe Mössbauer investigations for the spin glasses AuFe and Y(Fe, Al)2 in the temperature interval between the freezing temperature Tf and approximately 7 to 10Tf. All recorded spectra can be analysed with a model which takes into account these dynamics by allowing the formation of correlated states after a stochastically varying time τoff and their decay after a time τon, restricting the number of subspectra to the different number of Fe atoms in the first neighbour shell. Whereas for the different Fe environments, in addition to centre shift and quadrupole splitting, different hyperfine fields of the two stochastically formed states can always be resolved, the same set of τon and τoff values was obtained for all subspectra above approximately 4Tf. The external field hinders the decay of the correlated regions. The temperature dependence of ¿ on scales with Tf and exhibits a power law with exponents of –2 for the Fe-rich and –1 for the Fe-poor compounds.

Full textAbstract:
Abstract Neutron powder diffraction has been used to study the evolution of long range magnetic order in the pseudobinary CI 5 Laves phase system Ho1-xYxMn2. Particular attention has been paid to the nature of the Mn moment. At Y-rich compositions (x > 0.9) an incommensurate antiferromagnetic structure, similar to that of YMn2 is observed. Transition to the ordered state, as in YMn2, is accompanied by a 5% expansion of the unit cell, identifying the Mn moments, of 2.7 μB, as intrinsic. The magnetic structure of compositions with x<0.7 resembles that of HoMn2 and DyMn2, with only one quarter of the chemically equivalent Mn sites possessing a moment of 0.6 μB induced by the local symmetry of the antiferromagnetically ordered Ho sublattice. Transition to the ordered state is not accompanied by a cell expansion. Between x = 0.7 and x = 0.9 there is no longe range magnetic order, nor is there an expansion of the unit cell, suggesting the total absence of either induced or intrinsic Mn moments. The results indicate that a critical Mn-Mn near neighbour distance of 2.663 Å is necessary to sustain an intrinsic Mn moment in these compounds.

In 2016, there where 194 recognized independent states in the world, members of the United Nations Organization. There are very rich states among these countries, but most of them are comparatively poor and need the help and support of the rich ones. The size of these countries according to geographical area, the population, the size of GDP varies from country to country. Since the economic growth is one of the main indicator of countries’ welfare, it has become a challenging issue for the researchers worldwide. What factors influence the development of a national economy in the right way, making the living standards increase and the population wellbeing grow? This article has a goal to identify several competitive sectors of the economy that have potential to lead to sustainable economic growth for Republic of Moldova. The Republic of Moldova is relatively a young independent state, since the dissolution of USSR, and faces some problems that need to be solved in order to increase country’s welfare. The results of analysis showed that following industrial sectors: wine; textiles and apparel; information and communication technology; footwear; construction materials and furniture have the most potential for contributing to transformational growth in the Republic of Moldova economy. A big step in achieving this is signing the DCFTA with European Union. The importance of EU trade relations with the Republic of Moldova is of great impact on its national economy. The Republic of Moldova needs all the support and help of its powerful neighbour in order to achieve higher economic growth and to increase the competitivity of its products on EU market.

ABSTRACT In the local Universe, there are a handful of dwarf compact star-forming galaxies with extremely low oxygen abundances. It has been proposed that they are young, having formed a large fraction of their stellar mass during their last few hundred Myr. However, little is known about the fraction of young stellar populations in more massive galaxies. In a previous article, we analysed 404 000 Sloan Digital Sky Survey spectra to identify a surprisingly large sample of more massive very young galaxies (VYGs), defined to have formed at least $50{{\ \rm per\ cent}}$ of their stellar mass within the last 1 Gyr. Here, we investigate in detail the properties of a subsample of 207 galaxies that are VYGs according to all three of our spectral models. We compare their properties with those of control sample galaxies (CSGs). We find that VYGs tend to have higher surface brightness and to be more compact, dusty, asymmetric, and clumpy than CSGs. Analysis of a subsample with H i detections reveals that VYGs are more gas rich than CSGs. VYGs tend to reside more in the inner parts of low-mass groups and are twice as likely as CSGs to be interacting with a neighbour galaxy. On the other hand, VYGs and CSGs have similar gas metallicities and large-scale environments (relative to filaments and voids). These results suggest that gas-rich interactions and mergers are the main mechanisms responsible for the recent triggering of star formation in low-redshift VYGs, except for the lowest mass VYGs, where the starbursts would arise from a mixture of mergers and gas infall.

AbstractIn order to protect and develop valuable snappers (Lutjanus spp.), genetic diversity and molecular markers of five species (Lutjanus vitta, L. fulvus, L. fulviflamma, L. sebae and L. stellatus) were detected and analysed using random amplified polymorphic DNA (RAPD) and simple sequence repeats (SSR) techniques. The polymorphic loci ratio (P) (86.00–92.11%), the mean intraspecies genetic distances (D) (0.1775–0.3431) and the intraspecies genetic diversity indexes (Hi) (0.1022–0.1634) were calculated using the RAPD technique. The genetic diversities of L. fulviflamma and L. vitta were richest in terms of P, and D and Hi, respectively. The results of SSR showed that low effective numbers of alleles (1.7893–3.6591), medium average heterozygosities (0.332–0.676) and medium polymorphism information contents (PIC) (0.302–0.641) occurred in five species of snappers, indicating comparatively rich genetic diversity among these fish. Nine molecular markers in the products amplified by primers OPA8 and OPP10, and six molecular markers in 11 microsatellite loci were found to be useful as specific markers to identify five species of snappers. Two neighbour-joining (NJ) dendrograms based on the results of RAPD and SSR suggested that L. stellatus and L. sebae are closely related and clustered in one branch, with L. vitta, L. fulviflamma and L. fulvus in the other.

An electrocardiogram (ECG) records the electrical activity of the heart; it contains rich pathological information on cardiovascular diseases, such as arrhythmia. However, it is difficult to visually analyze ECG signals due to their complexity and nonlinearity. The wavelet scattering transform can generate translation-invariant and deformation-stable representations of ECG signals through cascades of wavelet convolutions with nonlinear modulus and averaging operators. We proposed a novel approach using wavelet scattering transform to automatically classify four categories of arrhythmia ECG heartbeats, namely, nonectopic (N), supraventricular ectopic (S), ventricular ectopic (V), and fusion (F) beats. In this study, the wavelet scattering transform extracted 8 time windows from each ECG heartbeat. Two dimensionality reduction methods, principal component analysis (PCA) and time window selection, were applied on the 8 time windows. These processed features were fed to the neural network (NN), probabilistic neural network (PNN), and k-nearest neighbour (KNN) classifiers for classification. The 4th time window in combination with KNN (k=4) has achieved the optimal performance with an averaged accuracy, positive predictive value, sensitivity, and specificity of 99.3%, 99.6%, 99.5%, and 98.8%, respectively, using tenfold cross-validation. Thus, our proposed model is capable of highly accurate arrhythmia classification and will provide assistance to physicians in ECG interpretation.

Living organisms are part of a highly interconnected web of interactions, characterised by species nurturing, competing, parasitizing and preying on one another. Plants have evolved cooperative as well as defensive strategies to interact with neighbour organisms. Among these, the plant-fungus associations are very diverse, ranging from pathogenic to mutualistic. Our current knowledge of plant-fungus interactions suggests a sophisticated coevolution to ensure dynamic plant responses to evolving fungal mutualistic/pathogenic strategies. The plant-fungus communication relies on a rich chemical language. To manipulate the plant defence mechanisms, fungi produce and secrete several classes of biomolecules, whose modeof- action is largely unknown. Upon perception of the fungi, plants produce phytohormones and a battery of secondary metabolites that serve as defence mechanism against invaders or to promote mutualistic associations. These mutualistic chemical signals can be co-opted by pathogenic fungi for their own benefit. Among the plant molecules regulating plant-fungus interaction, phytohormones play a critical role since they modulate various aspects of plant development, defences and stress responses. Intriguingly, fungi can also produce phytohormones, although the actual role of fungalproduced phytohormones in plant-fungus interactions is poorly understood. Here, we discuss the recent advances in fungal production of phytohormone, their putative role as endogenous fungal signals and how fungi manipulate plant hormone balance to their benefits.

Full textAbstract:
ABSTRACT We present the results of a photometric study of the early-type galaxy NGC 6876 and the surrounding globular cluster (GC) system. The host galaxy is a massive elliptical, the brightest of this type in the Pavo Group. According to its intrinsic brightness (Mv ∼ −22.7), it is expected to belong to a galaxy cluster instead of a poor group. Observational material consists of g′, r′, i′ images obtained with the Gemini/GMOS camera. The selected GC candidates present a clear bimodal colour distribution at different galactocentric radii, with mean colours and dispersions for the metal-poor (‘blue’) and metal-rich (‘red’) typical of old GCs. The red subpopulation dominates close to the galaxy centre, in addition to the radial projected distribution showing that they are more concentrated towards the galaxy centre. The azimuthal projected distribution shows an overdensity in the red subpopulation in the direction of a trail observed in X-ray that could be evidence of interactions with its spiral neighbour NGC 6872. The turnover of the luminosity function gives an estimated distance modulus (m − M) ≈ 33.5 and the total population amounts to 9400 GCs, i.e. a quite populous system. The halo mass obtained using the number ratio (i.e. the number of GCs with respect to the baryonic and dark mass) gives a total of ∼1013, meaning it is a very massive galaxy, given the environment.

Full textAbstract:
Random amplified polymorphic DNA (RAPD) markers were used to assess intraspecific variability and relationships in aerial yam (Dioscorea bulbifera L.). A total of 23 accessions from different geographic locations in Africa, Asia, and Polynesia were analyzed by 10 arbitrarily chosen GC-rich decamer primers. Using cesium chloride purified genomic template DNA, highly reproducible polymorphic fingerprints were generated by all 10 primers, resulting in a total of 375 informative characters. Only eight bands were monomorphic among all investigated accessions. A binary character matrix was generated by scoring for presence/absence of a band at a particular position, transformed into a matrix of pairwise distances using either the Jaccard or a simple matching coefficient, and analyzed by neighbour joining, UPGMA (unweighted pair group method with arithmetic averaging) cluster analysis, or split decomposition. All methods of data evaluation resulted in similar groupings that reflected the geographical origin of the samples. The African accessions formed a distinct isolated group, whereas Asian and Polynesian accessions proved to be more heterogeneous. With two exceptions (var. suavior and var. sativa), the RAPD data supported previous varietal classification based on morphological characters. Stepwise reduction of the number of evaluated characters did not affect branching patterns of the trees above a minimum threshold of 150. Key words : Dioscorea bulbifera, random amplified polymorphic DNA (RAPD), genetic variation, genetic relatedness.

Full textAbstract:
This review article is a critical inspection of Andrew Bula's collection of poems, Turns of Thoughts (2020). As such, critical searchlights are thrown on poems as “Turns of Thoughts”, “Who Knows”, “Keeping Vigil”, “Love to Love”, “Wall Gecko”, “Far Out to the Woods”, “King on Fours in the Wilds”, “Trekking Home on a Windy Night”, ‘Presence and Space”, “Neighbour, Let’s Hate Hatred”, "Much Minuses & Little Pluses", "To Illumine our Rich, Fine World". In investigating these pieces, the aim really is to uncover the message and artistry of Bula's poetry. There are, of course, other pieces in the anthology that are simply mentioned in this review, without depth analyses. In such circumstances, the tendency is to liken them to other piece(s) or, quite simply, to take a cursory view of them. And then there is a showcasing of dominant literary devices as found in the poems as Rhetorical Questions, Paradox, Simile, Metaphor, Personification, Allusion, and Code Mixing. In the end, it is made out that Bula’s poetry is one of emotional elation and it reveals high moral awareness of, and gratitude to, important members of the public who have positively impacted society. Likewise, it is discovered that the poems also explore nature, love, and philosophical themes, while employing literary devices such as have already been mentioned.

Full textAbstract:
Children’s sense and reasoning about territory and land ownership may develop differently in contexts of poverty and where narratives of dispossession are a part of daily life and are of political and historical significance, as is the case in the Palestinian refugee context in Lebanon. In this study we looked at how 3- and 5-year-old refugee Palestinian and American children distribute land among neighbors disputing over an unoccupied piece of land separating their properties. Children were required to make distributive justice decisions about 4 scripted scenarios that involved a pretend conflict between different types of neighbors (rich/poor; ingroup vs. outgroup; neighbors of the same material wealth and neighbors that were either poor or rich as well as ingroup members). Both 5-year-old Palestinian and American children showed inequality aversion, favoring the poor neighbor over the rich in their distributive justice decisions. This first finding suggests that being born into poverty does not make young children more sensitive to material inequity, even if the object of dispute is of particular cultural relevance. However, a second main finding suggests that extreme circumstances potentially translate into enhanced ingroup partialities, above and beyond the universal normative trend toward inequity aversion.

Full textAbstract:
This article examines ‘neighbouring’ as the setting in which cross-category relations develop and symbolic boundaries are constructed. The study is based on thirty in-depth interviews with residents living in a multi-ethnic and a mono-ethnic neighbourhood in Rotterdam, the Netherlands. The findings challenge the hoped-for outcomes of social mixing in neighbourhoods, as well as the view that boundary making is something inherent to multi-ethnic neighbourhoods only. Neighbour relations are often setting-specific (relations are interchangeable, scripted and bounded, and passively maintained), which is relevant for understanding the spatiality of neighbouring and the limited exchange of personal information between neighbours. Because neighbouring involves the balancing of personal privacy and close spatial proximity, the exchange of personal information is limited, while spatial proximity ensures easy access to observable (through seeing, hearing and smelling) categorical markers that signify class, ethnicity, lifestyle, etc. In this way, neighbour interaction reconstructs symbolic boundaries rather than breaking them down.

This study examined the on-line processing of French sentences in a grammaticality judgment experiment. Three age groups of French children (mean age: 6;8, 8;6 and 10;10 years) and a group of adults were asked to detect grammatical violations as quickly as possible. Three factors were studied: the violation type: agreement violations (number and gender) vs. word order violations; the violation position: early vs. late in the sentence; the target type of the violations: intra vs. interphrasal. An example of an early interphrasal verbal agreement violation follows: ‘Chaque semaine la voisine remplissent le frigo après avoir fait les courses au marché’ (Every week the neighbour fill the fridge after shopping at the market). The main developmental results were the following: not surprisingly, children were always slower than adults in the detection of grammatical violations. At each age level, morphological violations were more rapidly detected than word order violations. Each age group was faster at judging sentences with later occurring violations and the position effect was especially strong in the youngest groups. Finally, intraphrasal violations were more rapidly detected than interphrasal ones, this effect being observed only in the oldest groups (i.e. 10;10 years and adults). The results were compared to previous on-line data obtained in modern Greek (Kail & Diakogiorgi, 1998) showing strong similarities, even though Greek is a very rich morphological language. These results are discussed within the framework of the Competition Model, outlining the necessity to incorporate new processing constraints into the model.

ABSTRACT We present a supervised machine learning methodology to classify stellar populations in the Local Group dwarf-irregular galaxy NGC 6822. Near-IR colours (J − H, H − K, and J − K), K-band magnitudes and far-IR surface brightness (at 70 and 160 $\mu$m) measured from Spitzer and Herschel images are the features used to train a Probabilistic Random Forest (PRF) classifier. Point-sources are classified into eight target classes: young stellar objects (YSOs), oxygen- and carbon-rich asymptotic giant branch stars, red giant branch and red supergiant stars, active galactic nuclei, massive main-sequence stars, and Galactic foreground stars. The PRF identifies sources with an accuracy of ∼ 90 per cent across all target classes rising to ∼96 per cent for YSOs. We confirm the nature of 125 out of 277 literature YSO candidates with sufficient feature information, and identify 199 new YSOs and candidates. Whilst these are mostly located in known star-forming regions, we have also identified new star formation sites. These YSOs have mass estimates between ∼15 and 50 M⊙, representing the most massive YSO population in NGC 6822. Another 82 out of 277 literature candidates are definitively classified as non-YSOs by the PRF analysis. We characterize the star formation environment by comparing the spatial distribution of YSOs to those of gas and dust using archival images. We also explore the potential of using (unsupervised) t-distributed stochastic neighbour embedding maps for the identification of the same stellar population classified by the PRF.

In Burkina Faso, the Palmyra Palm Borassus aethiopum Mart. grows wild and gives natural stands in Central-Eastern and Eastern regions. The sap collected traditionally ferments spontaneously and is a rich medium that allows the growth of different microorganisms. This study aimed to identify yeasts and lactic acid bacteria (LAB) isolated from Borassus aethiopum Mart. fresh and fermented sap in Burkina Faso. A total of ninety strains including thirty LAB and sixty yeasts were isolated in the fresh and fermented sap. The isolates were characterized using standard biochemical method and sequencing of the V1 to V6 region of 16S rDNA of LAB and 28S rDNA of yeasts. The neighbour-joining method was used for the construction of phylogenetic tree with MEGA X software. After biochemical characterization and sequencing of the V1 to V6 region of 16S rDNA, twenty LAB strains (67%) were identified as Leuconostoc mesenteroides, seven (23%) as Enterococcus sp. and three (10%) as Enterococcus gilvus. Sequencing of the yeast 28S rDNA showed that 63% of the strains were Saccharomyces cerevisiae and 37% Pichia kudriavzevii. Leuconostoc mesenteroides and Saccharomyces cerevisiae are commonly isolated from several palm sap or wine of palm trees, but Enterococcus sp. and Pichia kudriavzevii are not commonly detected in palm wine. The LAB species Enterococcus gilvus identified in our study has not yet been isolated previously in palm wine. The yeasts and LAB isolated from Borassus aethiopum sap are the main microorganisms responsible for sap fermentation and could be used for several biotechnological applications.

ABSTRACT We present the Australian Square Kilometre Array Pathfinder (ASKAP) WALLABY pre-pilot observations of two ‘dark’ H i sources (with H i masses of a few times 108 $\rm {M}_\odot$ and no known stellar counterpart) that reside within 363 kpc of NGC 1395, the most massive early-type galaxy in the Eridanus group of galaxies. We investigate whether these ‘dark’ H i sources have resulted from past tidal interactions or whether they are an extreme class of low surface brightness galaxies. Our results suggest that both scenarios are possible, and not mutually exclusive. The two ‘dark’ H i sources are compact, reside in relative isolation, and are more than 159 kpc away from their nearest H i-rich galaxy neighbour. Regardless of origin, the H i sizes and masses of both ‘dark’ H i sources are consistent with the H i size–mass relationship that is found in nearby low-mass galaxies, supporting the possibility that these H i sources are an extreme class of low surface brightness galaxies. We identified three analogues of candidate primordial ‘dark’ H i galaxies within the TNG100 cosmological, hydrodynamic simulation. All three model analogues are dark matter dominated, have assembled most of their mass 12–13 Gyr ago, and have not experienced much evolution until cluster infall 1–2 Gyr ago. Our WALLABY pre-pilot science results suggest that the upcoming large-area H i surveys will have a significant impact on our understanding of low surface brightness galaxies and the physical processes that shape them.

AbstractDuring the last twenty years, Senegalese migration has shifted from West African cities to France, from France to its European neighbour countries and finally towards the United States of America. Whereas the secular French state discourages religious display, especially within public space, the more community-oriented USA is far from opposed to religious expression in the public sphere. In this article, I analyze how Senegalese migrants who have grown up in secular states (Senegal and/or France) use American public space to demonstrate their political and religious identity through the organization of special events. Even though the migrants, notably the political and religious activists, take into consideration the cultural and political differences between their different places of residence, they follow continuous strategies across their translocal spaces. Special events like the Murid Parade in July or the Senegalese presidential election campaign in spring 2000 provide rich empirical data for the analysis of the complex interaction between Senegalese inside and outside their country, their translocal networks and their connections to the local situation in New York City. The latter includes the different inhabitants of Harlem and the local geographical setting, the representatives of the state and the politics of migration, as well as the Mayor and his political program. The recently opened House of Islam, founded by members of the Murid Sufi order in Harlem, shows how deeply the Senegalese in the US are already rooted. However, the annual religious event organized by the Murids is only one demonstration of identity politics. In order to illustrate the diversity of the community, I show how the events organized during the Senegalese presidential election campaign in 2000 in New York City take into consideration the complexity of the religious, political and economic identities of the American Senegalese.

Iron-technetium alloys are of relevance to the development of waste forms for disposition of radioactive technetium-99 obtained from spent nuclear fuel. Corrosion of candidate waste forms is a function of the local cohesive energy () of surface atoms. A theoretical model for calculating is developed. Density functional theory was used to construct a modified embedded atom (MEAM) potential for iron-technetium. Materials properties determined for the iron-technetium system were in good agreement with the literature. To explore the relationship between local structure and corrosion, MEAM simulations were performed on representative iron-technetium alloys and intermetallics. Technetium-rich phases have lower , suggesting that these phases will be more noble than iron-rich ones. Quantitative estimates of based on numbers of nearest neighbors alone can lead to errors up to 0.5 eV. Consequently, atomistic corrosion simulations for alloy systems should utilize physics-based models that consider not only neighbor counts, but also local compositions and atomic arrangements.

This makes the Sgr dSph an ideal laboratory to study at the same time the chemical evolution of dwarf galaxies and their role in building bigger structures such as the MW. Since some years we are studying the stellar populations of the Sgr main body and stream, with particular attention to their detailed chemical composition. We collected detailed abundances (up to 22 elements, O to Eu) for 27 stars in the Sgr dSph main body, 5 in the associated globular cluster Terzan 7, and 12 more in the trailing Sgr tidal arm (UVES@VLT and SARG@TNG data). We are also conducting a large FLAMES@VLT chemical and dynamical analysis aimed at obtaining metallicities, alpha-elements content and radial velocities from automated analysis of the spectra. Finally, we just completed the first large scale photometric and spectroscopic survey of the stellar populations across all the dSph main body extension with VIMOS@VLT, aimed at exploring the variations in stellar populations and at deriving radial velocity memberships for future high resolution spectroscopic analysis. The picture emerging from all these studies portraits a large and extremely complex object, with signs of a long and still unclear evolution. Metallicity varies across three orders of magnitude ([Fe/H] from −3 to 0), CMDs change surprisingly from the core to the outskirts of the galaxy, and the chemical composition of the most metal rich objects show a very characteristic signature, with underabundant alpha elements, deficient Na, underabundant Fe-peak Mn, Co, Ni, Cu and Zn, and strongly enhanced n-capture elements La and Nd. This highly peculiar signature can also be effectively used to recognized stripped populations lost by Sgr in favour of the MW system, as clearly showed by the globular Palomar 12, which shows the same chemical anomalies detected in Sgr dSph.

The study attempts to seek evidence on regional economic integrationin driving labor productivity convergence in low-and middle-income East Asian states towards Japan, the country assumed to be the regional technology leader. The labor productivity convergence of low-and middle-income East Asian countries towards their rich neighbor is modelled against their national levels of innovation, technology spill-oversfrom the regional economic leader and their productivity differential with the frontier country. The hypothesized relationship is empirically verified for seven East Asian states, using a robust econometric approach. The time-series test estimates under Error Correction Representation yield absolute support in favor of valid productivity convergence occurring between Japan and its low-and middle income neighbors. However, panel data estimates generated with better statistical power outperform the time-series test findingsand these results reject the significance of Japan as the regional productivity growth driver for its regionaldevelopingstates.

Chromatin reorganization governs gene expression regulation during pre-implantation development. However, the global chromatin landscape and its dynamics in this period remain unexplored in bovine. In this study, we constructed a genome-wide map of accessible chromatin in bovine oocytes and early embryos using an improved assay for transposase-accessible chromatin with high-throughput sequencing (ATAC-seq). We analysed pools of 20 germinal vesicles or MII oocytes or 2-, 4-, 8-, 16-cell, morula, and blastocyst stage invitro-produced embryos. We conducted ATAC-seq on six pools for each stage and an additional four pools of invivo-derived morula and blastocysts and six replicates using individual Day 14 elongating embryos. We obtained ~110 million paired end reads uniquely mapped to the bovine reference genome for each stage. Hierarchical clustering, t-distributed stochastic neighbour embedding, and principal component analysis showed four distinct patterns for open chromatin status: (1) low accessibility in germinal vesicles and MII oocytes and in 2- and 4-cell embryos; (2) significantly elevated accessibility in 8-cell, 16-cell, and morula embryos; (3) less accessibility in blastocysts; and (4) extremely high accessibility in elongating embryos. This dynamic and sequential chromatin remodelling is consistent with transcription activation during the bovine minor embryonic genome activation from fertilization to 4-cell, major embryonic genome activation at 8-cell, first differentiation at blastocyst and drastic transcription initiation for embryo elongation. Genome-wide characteristics of accessible chromatin showed (1) accessible chromatin near the transcription start sites of active genes and CpG-rich promoters; (2) widespread accessible chromatin regions extensively overlapped with transposable elements; (3) distal peaks preferentially enriched for repeats including LINE, SINE, and LTR from 8-cell to morula embryos, especially for LTR, whereas enrichment in simple repeats were found from oocytes to 4-cell and in elongating embryos; and (4) highly stage-specific transcription factor motifs in distal peaks were unveiled. By integrating the maps of chromatin accessibility with bovine embryo transcriptomes and DNA methylomes, we found promoter accessibility and DNA methylation in bovine embryos correlated with both gene activities and CpG densities. Most importantly, we constructed the regulatory networks of stage-specific expressed genes and stage-specific activated genes with three omics datasets in bovine early embryos and revealed conserved and distinctive transcriptional regulatory networks between invivo- and invitro-derived embryos. This comprehensive analysis revealed critical features of the chromatin landscape and epigenetic reprogramming during bovine early embryo development.

ABSTRACTThis research examines phonological neighbourhoods in the lexicons of children acquiring English. Analyses of neighbourhood densities were done on children's earliest words and on a corpus of spontaneous speech, used to measure neighbours in the target language. Neighbourhood densities were analyzed for words created by changing segments in word-onset position (rhyme neighbours as in pin/bin), vowel position (consonant neighbours as in pin/pan/) and word-offset position (lead neighbours as in pin/pit). Results indicated that neighbours in children's early lexicons are significantly more often distinguished in word-onset position (rhyme neighbours) and significantly less often distinguished in word-offset position (lead neighbours). Moreover, patterns in child language are more extreme than in the target language. Findings are discussed within the PRIMIR framework (Processing Rich Information from Multidimensional Interaction Representations; Werker & Curtin, 2005). It is argued that early perceptual sensitivity aids lexical acquisition, supporting continuity across speech perception and lexical acquisition.
