THE CRIMINALISTIC CHARACTERISTIC OF THEFT IN CONSTRUCTION SECTOR
Authors: Зеленский Владимир Дмитриевич , Безбогин Александр Константинович
Published: August 2020

Криминалистическая характеристика хищений в сфере строительства представляет собой систематизированное описание криминалистически значимых признаков данной группы преступлений (хищения, совершенного путем мошенничества, а также хищения, совершенного путем присвоения или растраты). Криминалистическая характеристика хищения в строительстве должна состоять из криминалистически значимых элементов, описывающих данную группу преступлений и позволяющих следователю, опираясь на нее, осуществить качественное расследование. Знание следователем содержания криминалистической характеристики конкретного вида или группы преступлений и ее практическое использование позволяют ему в условиях дефицита информации на первоначальном этапе расследования минимизировать риск принятия неверных решений и совершения ошибочных действий. Элементами криминалистической характеристики хищений в строительной сфере являются: 1) сведения о способе хищения в строительстве (включающие в себя сведения о способах подготовки, совершения и сокрытия преступления); 2) сведения о характерных типичных следах (материальных и идеальных) совершенного или совершаемого хищения в строительстве. Знание содержания именно этих элементов следователем на первоначальном этапе расследования хищений в строительной сфере обеспечат верный выбор направления расследования и оперативное проведение следственных действий по обнаружению и изъятию доказательств, сведя к минимуму их возможную утрату.

Criminalistic characteristics of theft in the construction sector is a systematic description of criminally significant features of this group of crimes (theft committed by fraud, as well as theft committed by appropriation or embezzlement). Criminalistic characteristics of theft in construction sector should consist of criminally significant elements that describe this group of crimes and allow the investigator, based on it, to carry out a qualitative investigation. The investigator's knowledge of the content of the forensic characteristics of a particular type or group of crimes and its practical use allow him to minimize the risk of making incorrect decisions and committing erroneous actions in the context of a lack of information at the initial stage of the investigation. The elements of criminalistic characteristics of theft in the construction sector are: 1) information about the method of theft in construction (including information about the methods of preparation, Commission and concealment of the crime); 2) information about the characteristic typical traces (material and ideal) of theft committed or committed in construction. Knowledge of the content of these elements by the investigator at the initial stage of the investigation of theft in the construction sector will ensure the correct choice of the direction of investigation and prompt conduct of investigative actions to detect and remove evidence, minimizing their possible loss.

Carboxylate sensing solid-contact ion-selective electrodes (ISEs) were created to provide a proof-of-concept ISE development process covering all aspects from in silico ionophore design to functional sensor characterization. The biscarbazolylurea moiety was used to synthesize methylene-bridged macrocycles of different ring size aiming to fine tune selectivity towards different carboxylates. Cyclization was achieved with two separate strategies, using either amide synthesis to access up to –[CH2]10– macrocycles or acyl halides to access up to –[CH2]14– macrocycles. Seventy-five receptor–anion complexes were modelled and studied with COSMO-RS, in addition to all free host molecules. In order to predict initial selectivity towards carboxylates,1H NMR relative titrations were used to quantify binding in DMSO-d6/H2O solvent systems of two proportions – 99.5%:0.5% m/m and 90.0%:10.0% m/m, suggesting initial selectivity towards acetate. Three ionophores were selected for successful sensor prototype development and characterization. The constructed ion-selective electrodes showed higher selectivity towards benzoate than acetate, i.e., the selectivity patterns of the final sensors deviated from that predicted by the classic titration experiments. While the binding constants obtained by NMR titration in DMSO-d6/H2O solvent systems provided important guidance for sensor development, the results obtained in this work emphasize the importance of evaluating the binding behavior of receptors in real sensor membranes.
An Astrometric Planetary Companion Candidate to the M9 Dwarf TVLM 513–46546

Published: August 2020

Astrometric observations of the M9 dwarf TVLM 513–46546 taken with the VLBA reveal an astrometric signature consistent with a period of 221 ± 5 days. The orbital fit implies that the companion has a mass m

p
 = 0.35−0.42 M
J, a circular orbit (e ≃ 0), a semimajor axis a = 0.28−0.31 au, and an inclination angle i = 71°−88°. The detected companion, TVLM 513b, is one of the few giant-mass planets found associated with ultracool dwarfs. The presence of a Saturn-like planet on a circular orbit 0.3 au from a 0.06−0.08 M
⊙ star represents a challenge to planet formation theory. This is the first astrometric detection of a planet at radio wavelengths.

In many space, astrophysical, and laboratory plasmas the energy contained in the magnetic field or plasma flow exceeds the thermal energy. Magnetic field (

) annihilation, often enabled by magnetic reconnection, transfers magnetic energy to particles. Shocks transfer bulk flow energy to particles. If there is a sufficiently large energy transfer, strong turbulence (∣

∣/∣
B
∣ ∼ 1) develops, which, in turn, can result in nonthermal acceleration. In this article, we investigate acceleration in a finite-sized region of strong turbulence driven by magnetic reconnection with analytical modeling and test-particle simulations. This research is based on detailed observations in the Earth’s magnetotail. We find that the primary transfer of magnetic energy to particle energy is advanced by large-amplitude electric field structures (

) generated by the strong turbulence. To no surprise, ion energization is dominated by intense DC

,

near the ion cyclotron frequency (f

ci
), and/or

variations at scales near the ion gyroradius. Electron energization comes from higher-frequency

. The turbulent cascade continuously regenerates

near f

ci
and higher frequencies. Importantly, the turbulence also creates magnetic depletions that can trap particles and considerably increase their dwell time in regions of strong energization, which substantially enhances nonthermal acceleration. Moreover, energization is primarily perpendicular to

, so particles have difficulty escaping regions of depleted

, which can lead to near runaway acceleration. We discuss how this process may be active in large-scale settings such as supernova shells and may contribute, at least in in part, to the development of the cosmic ray spectrum.

The Magnetospheric Multiscale Mission observes, in detail, charged particle heating and substantial nonthermal acceleration in a region of strong turbulence (

, where

is the magnetic field) that surrounds a magnetic reconnection X-line. Magnetic reconnection enables magnetic field annihilation in a volume that far exceeds that of the diffusion region. The formidable magnetic field annihilation breaks into strong, intermittent turbulence with magnetic field energy as the driver. The strong, intermittent turbulence appears to generate the necessary conditions for nonthermal acceleration. It creates intense, localized currents (

) and unusually large-amplitude electric fields (

). The combination of turbulence-generated

and

results in a significant net positive mean of

, which signifies particle energization. Ion and electron heating rates are such that they experience a fourfold increase from their initial temperature. Importantly, the strong turbulence also generates magnetic holes or depletions in

that can trap particles. Trapping considerably increases the dwell time of a subset of particles in the turbulent region, which results in significant nonthermal particle acceleration. The direct observation of strong turbulence that is enabled by magnetic reconnection with nonthermal particle acceleration has far-reaching implications, since turbulence in plasmas is pervasive and may occupy significant volumes of the interstellar medium and intergalactic space. For example, strong turbulence from magnetic field annihilation in the supernova nebulae may dominate large volumes. As such, this observed energization process could plausibly contribute to the supply and development of the cosmic-ray spectrum.
Brackett-γ as a Gold-standard Test of Star Formation Rates Derived from SED Fitting
Authors: Pasha Imad , Leja Joel , van Dokkum Pieter G. , Conroy Charlie , Johnson Benjamin D.
Published: August 2020

Using a local reference sample of 21 galaxies, we compare observations of the 2.16 μm Brackett-γ (Brγ) hydrogen recombination line with predictions from the Prospector Bayesian inference framework, which was used to fit the broadband photometry of these systems. This is a clean test of the spectral-energy-distribution-derived star formation rates (SFRs), as dust is expected to be optically thin at this wavelength in nearly all galaxies; thus, the internal conversion of SFR to predicted line luminosity does not depend strongly on the adopted dust model and posterior dust parameters, as is the case for shorter-wavelength lines such as Hα. We find that Prospector predicts Brγ luminosities and equivalent widths with small offsets (∼0.05 dex) and scatter (∼0.2 dex), consistent with measurement uncertainties, though we caution that the derived offset is dependent on the choice of stellar isochrones. We demonstrate that even when the Prospector-derived dust attenuation does not well describe, e.g., Hα line properties or observed reddening between Hα and Brγ, the underlying SFRs are accurate, as verified by the dust-free Brγ comparison. Finally, we discuss in what ways Brγ might be able to help constrain model parameters when treated as an input to the model, and we comment on its potential as an accurate monochromatic SFR indicator in the era of JWST multiobject near-IR spectroscopy.
Standardisation of bioacoustic terminology for insects
Authors: Baker Edward , Chesmore David
Published: August 2020

After reviewing the published literature on sound production in insects, a standardised terminology and controlled vocabularies have been created. This combined terminology has potential for use in automated identification systems, evolutionary studies, and other use cases where the synthesis of bioacoustic traits from the literature is required. An example implementation has been developed for the BioAcoustica platform. It is hoped that future development of controlled vocabularies will become a community effort.
Observations on the Isturgia limbaria (Fabricius, 1775) / roraria (Fabricius, 1776) complex (Lepidoptera, Geometridae, Ennominae)
Authors: Flamigni Claudio , Fiumi Gabriele
Published: August 2020

TheIsturgia limbaria(Fabricius, 1775)/roraria(Fabricius, 1776) complex is analyzed, taking into consideration the external morphology of the adults (coloration and pattern of upperside and underside of wings), the morphology of the female genitalia (signum and lamella postvaginalis), of the tympanal organs and of the preimaginal stages, as well as molecular data. Based on the molecular data and morphology of signum and tympanic organs, the populations of this complex can be divided into two groups, one more western (with the taxalimbarias. str. anddelimbaria), distributed east to north-western Italy and part of Germany, and one more eastern (with the taxarorarias. str.,rablensisandanzascaria), distributed west to northern and eastern Piedmont (Italy) and north-eastern and south-eastern Germany. However, there are no consistent differences between the two groups in the diagnostic characters used until now to identify the two taxa (pattern of the wing upperside and underside). Although there is a considerable genetic distance between these two groups, the correlation between molecular differences and morphological characters (size of the signum and presence ̶ or absence ̶ of a roundish lobe in the bullae tympani) is not completely constant and the two groups of populations are not completely separated from each other: some populations of the northern Apennines (taxondelimbaria) cannot be clearly attributed to one or the other group. In the absence of constant morphological characters associated with the molecular differences and in the presence of Italian populations with intermediate characters, we suggest that the different taxa of this complex be considered as subspecies of the same species, as already proposed by Povolný and Moucha (1957, 1959). However, the data available do not allow definitive clarification of the taxonomic problem and further research is necessary.
Welcome to the Czech Republic again! Rare northern mosses Calliergon megalophyllum and Drepanocladus sordidus (Amblystegiaceae) in South Bohemia in light of their European distribution and habitat preferences

Two aquatic moss species, Calliergon megalophyllum and Drepanocladus sordidus (Amblystegiaceae, Bryophyta), which had been considered extinct in the Czech Republic, were found in the Třeboň Basin, South Bohemia, in 2016–2017. They co-occurred in extensive reed- and sedge-dominated fen pools with humic water on the shore of an old fishpond and the former species was also discovered in a small humic pool in an old shallow sand-pit. The new Czech sites of these rare boreal species represent one of the southernmost known outposts within their entire European range. Previously, the two species were only known from single records in the Czech Republic from the late 19th and early 20th centuries. To confirm our morphological observations, we used phylogenetic analyses of DNA sequence variation in four chloroplast loci (atpB-rbcL, trnL-trnF, rpl16, trnG) and one nuclear region, the internal transcribed spacers of ribosomal DNA (ITS). We found (1) monophyly of all Calliergon megalophyllum specimens tested; (2) based on chloroplast DNA sequences, monophyly among all Drepanocladus sordidus specimens and representatives of Pseudocalliergon turgescens and P. lycopodioides moss species; (3) based on nuclear ITS sequences, monophyly of all original D. sordidus specimens. These results corroborate morphological studies and thus confirm the existence of natural sites for the studied moss species in the Třeboň Basin, South Bohemia, Czech Republic.
Vivre pour raconter au pays sans mémoire

Published: August 2020

Les turbulences de tous ordres qui secouent le monde actuel affectent de manière de plus en plus brutale l’espace des récits et de la mémoire. S’affrontent ici la politique négationniste propre au révisionnisme historique – encouragé par des démagogues de toutes origines – et la mémoire des victimes, et se dévoile un jeu de tensions où la mémoire collective trouve à se renforcer dans diverses formes de créations artistiques et intellectuelles. Dans ce contexte, l’article propose d’ouvrir les parcours de formation à ces occasions de transformation que sont les images lorsqu’elles touchent le réel, ici avec les archives photographiques de Jesús Abad Colorado et les sculptures ou les installations de Doris Salcedo, les deux figures aujourd’hui les plus représentatives de l’art et de la mémoire en Colombie.
Percées, sur les traces de l’ancien asile : une expérience d’automédialité collective en milieu psychiatrique
Authors: Offroy Cécile , Pubert Laure
Published: August 2020

Percées est un projet de recherche-création collaborative conduit à l’hôpital psychiatrique de Ville-Evrard sur les traces de l’ancien asile. Elle puise dans les ressources de l’intersubjectivité et de l’installation multimédia pour dégager la matérialité d’une mémoire partageable et recréée, apte à déporter le regard vers un ailleurs repensé dans une dynamique du commun. Le médium photographique et l’interpénétration des récits s’enrichissent, s’alimentent, se transforment réciproquement.
Enfance et dictature . Reconstruire la vie entre mémoire et imaginaire
Authors: Erbetta Alejandro
Published: August 2020

Enfance et dictature s’inscrit dans une recherche artistique sur la mémoire qui interroge sa valeur d’objectivité à travers ses mouvances temporelles, les surimpressions des souvenirs, les constructions personnelles et historiques dont elle est la dépositaire, et l’histoire qui peut s’écrire au fil des images. Ce projet aborde la question de savoir comment l’enfance de l’auteur a pu être vécue comme une période heureuse, alors qu’il habitait Buenos Aires à proximité d’un centre clandestin de détention et d’une base militaire, et procède à une relecture de cette période de vie qui a aussi été le moment le plus obscur de l’histoire du pays.
La pratique de l’improvisation comme techniques de soi
Authors: Granjon Fabien
Published: August 2020

Cet article se fonde sur une enquête ethnographique conduite depuis quatre années à Uzeste, base arrière de la Compagnie Lubat ( http://www.cie-lubat.org ), où s’actualise, depuis plus de quarante ans, un « devoir d’invention d’une ruralité critique » (Denouël & Granjon, 2018). Le front culturel de résistance populaire (Granjon, 2016) qui s’y est développé s’appuie centralement sur des pratiques artistiques variées dont le ressort principal est l’improvisation et dont il nous semble possible de la considérer, depuis l’appareil conceptuel foucaldien, comme une forme de parrêsia .
Mon histoire de spectateur
Authors: Kerouanton Joël
Published: August 2020

Le parcours de spectateur, aussi banal qu’il puisse paraître dans l’histoire d’une vie, peut recouvrir de multiples strates de savoirs sensibles. En faisant appel à l’écriture créative – seule façon de donner à voir les territoires de l’ambiguïté –, l’auteur met en récit sa sensation originelle d’idiotie culturelle, puis son choc émancipateur face à des formes esthétiques produites en présence de corps hors-normes. Les spectacles devenant un médium pour se regarder dans le monde et regarder le monde, l’auteur en fera usage dans le champ social puis dans le champ culturel, non sans résistance. Porté par l’imaginaire de communautés interprétatives de spectateurs, l’auteur concevra des dispositifs participatifs alimentant Le Dico du spectateur , une typologie de spectateur générant des définitions théorico-rigolotes – fil rouge de ce récit.

Depuis sa création, Facebook est devenu le réseau social le plus actif et attractif au monde et un des moyens pour ses utilisateurs de se mettre en scène et de construire leurs relations. Partant de l’hypothèse que les publications sur Facebook dévoilent à la fois les enjeux de la plateforme et les formes d’expression de soi dans la contemporanéité, l’article met en avant les éléments qui permettent de considérer l’usage de Facebook comme relevant d’une démarche automédiale participant à une fabrique de soi dans un monde hyperconnecté, peuplé d’identités narratives, visuelles et numériques, dans lequel l’espace et le temps sont en constante transformation.

Les racines transatlantiques du show business (1850-1910)
Authors: Corbière Laetitia
Published: August 2020

En Europe, la première moitié du xix e  siècle marque la généralisation du concert payant et des tournées musicales. La musique devient alors un bien culturel valorisable et échangeable. Cependant, le système de production musicale qui s’élabore alors reste un système mixte dans lequel persistent les traditions de mécénat et les habitudes corporatistes. Or, lorsqu’ils tentent d’importer le concert aux États-Unis vers 1850, les premiers imprésarios américains ne peuvent développer l’activité musicale qu’en se fondant sur la seule logique capitaliste. Dès lors, un nouveau mode d’exploitation du concert se développe qui transforme la vie musicale en profondeur. L’internationalisation des circulations musicales témoigne ainsi d’une logique nouvelle de mondialisation artistique.

Philippe Devillers ne fut pas seulement un journaliste et un politologue spécialiste du Sud-Est asiatique. Il œuvra également comme lanceur d’alertes : son Histoire du Viêt-Nam de 1940 à 1952 a été délibérément conçue comme un recueil de fuites organisées par les opposants à la guerre d’Indochine au sein de l’appareil d’État. À partir de la décennie 1960, il contribua de manière décisive au lancement en France des études universitaires sur l’Asie du Sud-Est contemporaine. L’article retrace l’itinéraire intellectuel et politique de Devillers à partir de ses publications et de ses archives personnelles.
Tensions à l’Unesco autour du centenaire de Lénine. Les enjeux d’une commémoration (1970)
Authors: Maurel Chloé
Published: August 2020

En 1970, l’Unesco, organisation des Nations unies pour l’éducation, la science et la culture, alors au faîte de son prestige et de son influence, organise à l’initiative de l’URSS une commémoration du centenaire de la naissance de Lénine (1870-1924). Cela se traduit par la tenue d’un colloque sur Lénine à Tampere (Finlande) et par la publication d’un numéro du Courrier de l’Unesco consacré en partie à Lénine. Cette commémoration, et les luttes et affrontements diplomatiques feutrés qui se sont déroulés en coulisses entre les diplomates américains, britanniques, français et soviétiques, et les fonctionnaires de l’Unesco, montrent que cette institution internationale a été instrumentalisée par les grandes puissances pendant la Guerre froide. Théoriquement apolitique, l’Unesco a été un lieu d’affrontements politiques entre les deux blocs.
La « Françafrique », instrument d’un soft power associatif et « stigmate » pour la politique africaine de la France
Authors: Alleno Kevin
Published: August 2020

Cet article vise à montrer l’origine du concept de « Françafrique » qui constitue le soft power de l’association Survie. Pensé par son ancien président François-Xavier Verschave, qui reprend une expression de Félix Houphouët-Boigny, ce concept structure aujourd’hui le débat sur l’action de la France en Afrique. Après avoir montré les thèses véhiculées par lui, il s’agit d’observer sa diffusion dans le débat public français puis ses conséquences sur l’action de la France en Afrique. Cette représentation dépréciative de la politique africaine de la France constitue pour elle un « stigmate » que les responsables français contrent difficilement.
Océans, cosmos, Antarctique : de nouveaux espaces de conquête ?
Authors: Pic Pauline , Lasserre Frédéric
Published: August 2020

On considère aujourd’hui les océans – et notamment les océans polaires – mais aussi l’espace, comme les « dernières frontières ». Ces espaces de projection de puissance pour certains États sont également porteurs d’enjeux particuliers, environnementaux notamment, qui invitent à repenser les modes d’action politique. Comment les États font-ils face à ces espaces non traditionnels, et comment y structurent-ils leur action ? Nous proposons dans cet article, à travers plusieurs exemples concrets, d’entamer la réflexion en mettant en relief certaines logiques qui sous-tendent l’organisation de l’action politique internationale dans ces espaces. Il s’agit de s’interroger sur la nature de ces espaces et à ce que l’on entend par conquête. Car la communauté internationale a su encadrer les appétits potentiels dans des conventions internationales. Mais cela ne signifie pas que ces cadres juridiques aient la capacité d’éteindre toutes les tensions suscitées par le désir de contrôler ces espaces. Les questions posées par l’actualité soulignent par ailleurs des enjeux complexes et de nature différente, ayant trait tantôt à la souveraineté, en Antarctique par exemple, tantôt aux droits souverains, lorsque l’on parle de plateaux continentaux étendus, ou du droit de placer des satellites en orbite… Ces questions se renouvellent aussi en lien avec la présence de nouveaux acteurs, qu’ils soient étatiques ou privés. Comment ces acteurs envisagent-ils ces espaces non traditionnels ?
Odd random attractors for stochastic non-autonomous Kuramoto-Sivashinsky equations without dissipation
Authors: Li Yangrong , Yang Shuang , Zhang Qiangheng
Published: August 2020

We study the random dynamics for the stochastic non-autonomous Kuramoto-Sivashinsky equation in the possibly non-dissipative case. We first prove the existence of a pullback attractor in the Lebesgue space of odd functions, then show that the fiber of the odd pullback attractor semi-converges to a nonempty compact set as the time-parameter goes to minus infinity and finally prove the measurability of the attractor. In a word, we obtain a longtime stable random attractor formed from odd functions. A key tool is the existence of a bridge function between Lebesgue and Sobolev spaces of odd functions.
Visualizing the invisible: COVID-19 pandemic season in Saigon
Authors: Robert Christophe
Published: August 2020

The COVID-19 pandemic disrupted daily life in Vietnam and Saigon/Ho Chi Minh City in ways that diverged from reporting in Vietnamese and foreign media. Images of empty streets with no traffic became features of Western reporting and were mimicked by Vietnamese media. Yet, in alleyways and smaller streets, life went on. Through a sequence of images of street scenes and COVID-related signage, I discuss ethnographically the importance of the informal sector for providing the basic necessities of life in the city. This is especially true for the basic provision and sale of food. Images of street markets show the key roles of women to ensure these essential tasks were not disrupted during the pandemic. This informal sector work, like the role of women in society in particular, is rendered invisible, considered routine and habitual. The sudden disruption from COVID-19 brought into view daily patterns of life and work, and placed them temporarily in a new light.
Ventricular tachycardia triggered by pregnancy in left-ventricular non-compaction cardiomyopathy: a controversial indication to automated defibrillator implantation
Authors: Gherbesi Elisa , Bonanomi Carla , Bottari Vera , Danzi Gian Battista
Published: August 2020

Left-ventricular non-compaction (LVNC) is a rare form of cardiomyopathy. Its clinical presentation is highly variable and during pregnancy is frequently associated with heart failure, embolic events, and arrhythmias. Herein we report a case of a woman with left ventricular non-compaction who had an automated defibrillator implantation for recurrent ventricular arrhythmias during pregnancy. During pregnancy and at long-term follow-up no interventions of the device were documented. In conclusion, the management of malignant arrhythmias during pregnancy is one of the concerns for patients with LVNC and requires a careful approach in third-level centers.
Racism as a challenge for church and society in democratic South Africa: Human dignity perspective
Authors: Modise Leepo J.
Published: August 2020

The image of God has been vandalised by racism in South Africa, which it is argued is a sin. It is an ecclesiological responsibility to address the vandalised image of God in South Africa. The author will argue from the human relationship as a build-up to the Theanthropocosmic principle. This principle denotes the relationship between God (theos) the human being (anthropos) and the physical-organic environment (cosmos). For addressing this responsibility, the grounds of internal racism are exposed using a philosophical interpretation. According to the author, there is a correlation between sin and racism. The latter is viewed as multidimensional from a Theanthropocosmic perspective.The theoretical framework will be within hamartiology and soteriology. The philosophical interpretation will be utilised to broaden the understanding of the theological problem of the vandalised image of God.
Riemann–Roch isometries in the non-compact orbifold setting
Authors: Freixas i Montplet Gerard , von Pippich Anna-Maria
Published: August 2020

We generalize work of Deligne and Gillet–Soulé on a functorial Riemann–Roch type isometry, to the case of the trivial sheaf on cusp compactifications of Riemann surfaces of finite type

\Gamma\backslash\mathbb H

, for

\Gamma\subset\mathrm {PSL}_{2}(\mathbb R)

a Fuchsian group of the first kind, equipped with the Poincaré metric. This metric is singular at cusps and elliptic fixed points, and the original results of Deligne and Gillet–Soulé do not apply to this setting. Our theorem relates the determinant of cohomology of the trivial sheaf, with an explicit Quillen type metric defined in terms of the Selberg zeta function of

\Gamma

, to a metrized version of the tautological line bundle in the theory of moduli spaces of pointed orbicurves, and the self-intersection bundle of a suitable twist of the canonical sheaf

\omega

. We make use of surgery techniques through Mayer–Vietoris formulas for determinants of Laplacians, in order to reduce to explicit evaluations of such for model hyperbolic cusps and cones. We carry out these computations, which are of independent interest for theoretical physics, and can be adapted to other geometries. We go on to derive an arithmetic Riemann–Roch formula in the realm of Arakelov geometry, which applies in particular to integral models of modular curves with elliptic fixed points. This vastly extends previous work of the first author, whose deformation-theoretic methods were limited to torsion free Fuchsian groups. As an application, we treat in detail the case of the modular curve

X(1)

, and we show the interesting arithmetic content of the metrized

\Psi

line bundles. From this, we answer the longstanding question of evaluating the Selberg zeta special value

Z'(1, \mathrm {PSL}_2 (\mathbb Z))

. The result is expressed in terms of logarithmic derivatives of Dirichlet

This study examines the implication of contract farming on Olam Out-growers farming scheme in Kwara State, Nigeria. The objectives of the study are to determine the costs and returns to production of rice, assess the productivity level of rice, evaluate the technical efficiency of rice farm and identify the determinants of the technical inefficiency of the rice farms in contract farming. In this study, the average net farm income of the rice farmers under the scheme was N191,862.56 and the land productivity level was 2,006.04kg/ha. The technical efficiency of the rice farm was estimated using Cobb-Douglas Stochastic Frontier Production function which shows that likelihood coefficients for quality of seeds, hired labour and farm size were statistically significant at 1% level. Likewise, the determinants of technical efficiency among the farmers were household size and farming experience. The results further show that the contract farming scheme has a positive impact on the lives of rice farmers. Therefore, there is a need for partnership with private contract farming outfits in order to improve the current level of access to inputs by rice farmers.

Published: August 2020

The study ascertained the determinants of households’ preference for beef to pork in Umuahia Metropolis of Abia State, Nigeria. Using multi-stage random sampling procedure, data were collected from eighty household heads for the study. Data collected were analyzed using descriptive  statistics, ordinary least square and probit regression analysis. Findings from the study showed that beef was most preferred with 63.75% of  households indicated preferences for beef to pork while 36.25% of households preferred port to beef. The study also revealed age of household head, and price of meat negatively influenced meat consumption while household size and average monthly income had positive influence and the R2 was 0.675 which implied 67.5% of the variation in the meat consumption was explained by the independent variables. From the probit regressionmodel the results showed age of household heads and price of pork had a negative coefficient and were significant at 10% and 5% level of probability respectively, while household size, education level, and household income had positive coefficient and were significant at 1%, 5%, and 1% level of probability, respectively. The Chi square was 135.485 which indicated the goodness of fit for the equation and was significant at 1% level of probability. The study recommended beef marketing as a good venture in the study area; beef was most preferred meat in the study. Hence, it is recommended that unemployed persons should be encouraged to venture into beef marketing; also, there is huge potential for pork marketing in the study area.

Attraction of <Callosobruchus maculates fabricius (Coleoptera: Chrysomelidae: Bruchinae) to pods of cowpea plants at different developmental stages
Authors: Ahuchaogu C.E. , Ojiako F.O.
Published: August 2020

The cowpea beetle, Callosobruchus maculatus Fab. is an economically important pest of stored grain and causes serious damage to stored peas. The application of pesticides has been the generic control measure due to its effectiveness, affordability and ease of application. However, due to the apparent health and environmental consequences with pesticides, stakeholders are advocating for an alternative management approach that has less social and environmental impact and is more sustainable. Consequently, this study examined the attraction of mated female to volatile blends collected from pods of cowpea plants (Borno-brown and black-eyed cultivars) at three developmental stages  developing podsie; 15-17 days after anthesis (daa), fully developed pods (18-20 daa) and mature pods (> 20 daa). The beetles’ responses to the pods’ odour were determined using a two-arm olfactometer, and gas chromatography-mass spectrometry (GC-MS) was used to identify and  quantify the volatile compounds collected from the pods. The results showed that female C. maculatus attraction increased with the pod’s age, and that the composition and abundance of volatile compounds varied between cowpea cultivars and the pod’s developmental stage. These findings form an important bases towards developing alternative approach for the management of bruchids.

An assessment of the impact of human activities on wild birds and fishes in Dagona Waterfowl Sanctuary, Nigeria
Authors: Saleh A. , Ahmed A.
Published: August 2020

Natural resources management and conservation has been a persistent theme in discourse of human survival and environmental development. Conservation means the sustainable use and protection of natural resources. It is also seen as the process through which natural resources are  managed to allow partial or total exploitation for individual, community, or commercial use without jeopardizing the long-term ability of the  resource base for future generations with minimal environmental damages. The study employed systematic sampling techniques in selecting the respondents for the interview. The selection was based on the settlement arrangement in the study site as sampling frame. The structured  questionnaires were administered to the respondents with aid of research assistant for proper interpretation of the questionnaire to local language (Bade). The study found that there were different bird species both native and migratory birds from Europe and other parts of the world. The use of these birds includes tourism, source of meat, income and beautification of the natural environment. Farming hunting and fishing remain the dominant economic activities that provide income, food and tourism in the area. Hunting and fishing reduces the number as well as the  composition of birds and fish species in the area. Protopterrus annectens and Egretta garzetta were the dominant fish and bird species respectively. A lot of efforts were made to conserve and protect the waterfowl against natural and anthropogenic effects from national and international  environmental concern organizations.

Information Extraction from Electronic Medical Records using Natural Language Processing Techniques
Authors: Ogbuju E. , Obunadike G.N.
Published: August 2020

Patients share key information about their health with medical practitioners during clinic consultations. These key information may include their past medications and allergies, current situations/issues, and expectations. The healthcare professionals store this information in an Electronic Medical Record (EMR). EMRs have empowered research in healthcare; information hidden in them if harnessed properly through Natural Language Processing (NLP) can be used for disease registries, drug safety, epidemic surveillance, disease prediction, and treatment. This work illustrates the application of NLP techniques to design and implement a Key Information Retrieval System (KIRS framework) using the Latent Dirichlet Allocation algorithm. The cross-industry standard process for data mining methodology was applied in an experiment with an EMR dataset from PubMed todemonstrate the framework. The new system extracted the common problems (ailments) and prescriptions across the five (5) countries presented in the dataset. The system promises to assist health organizations in making informed decisions with the flood of key information data available in their domain.

Published: August 2020

Effects of phosphorous (P) level on performance, yield and nutritional value of Celosia argentea L. were evaluated with the aim of determining the P level that supports the best growth, yield and nutritional qualities of the crop. The levels of P were: normal (1.348 mg·kg-1 of P/pot, NP), medium (6.743 mg·kg-1 of P/pot, MP), high (13.48 mg·kg-1 of P/pot, HP) and no P application (control, CP). The crop growth rate (CGR) increased with  increase in phosphorus gradients (NP = 0.05 g/m2·d-1, MP = 0.09 g/m2·d-1 and HP = 0.12 g/m2·d-1). High and medium P rates increased the relative growth rate (RGR), HP had the highest RGR (0.05 g·g-1/day) followed by MP (0.04 g·g-1/day). Addition of P increased leaf area (LA) of C. argentea. Crude protein of the control was higher (5.56%) compared to the other P treatments (NP = 5.14, MP = 5.11 and HP = 5.03%). Phosphorus applications were beneficial for growth and enhancement of nutritional quality of C. argentea. NP and MP are recommended for growing this vegetablecrop.

Published: August 2020

The study focused on the structure, conduct and performance of timber market in Ife-east Local Governments of Oyo state. The major objective of  this study is to assess the marketing pattern of timber in the study areas. The research method used for achieving the general objectives involved Descriptive Statistics and Gini Coefficient. Variations were observed in the price of the timber of the same species but different size because price determination is based on bargaining power. The result showed majority of respondents (58.8%) had secondary education, Muslim was dominant (54.6%) in the timber marketing and majority of marketers had regular supply of their product. . Government policy, high cost of transportation, inadequate credit facilities and high cost of energy and power were some of the constraints faced by timber marketers in the study area. The use of modern equipment and machines are needed to replace the outdated equipment in order to increase the output and profit. The level of access to credit facilities should be improved upon by encouraging the respondent to form cooperative societies so that they can mobilize enough working capital for their business.

Classical Evaluation of Zero, Incomplete and Complete Treatment Effects on SEIRS Model Dynamics
Authors: Sangotola A.O. , Oyewole O.
Published: August 2020

In this research work, we extend the classical SEIR model to accommodate the effect of zero, incomplete and complete treatment on the dynamics of the model. The basic reproduction number (Ro) of the model dynamics is obtained by using the next generation matrix approach. The disease free equilibrium point of the model is found to be locally asymptotically stable if Ro < 1. A suitable Lyapunov function is constructed to determine the global stability of the disease free equilibrium point. Numerical simulation is carried out to determine the effect on the compliance to the treatment  prescription.
