description: Emigration has become a significant issue that cannot be overlooked globally as it is germane in achieving the 2030 Sustainable Development Goal of ending poverty. This study assessed the effects of emigration on the poverty status of farming households in Edo State, Nigeria. A total of 297 farmers were selected randomly from four Local Government Areas across the state. Structured interview schedule was used to obtain primary data from the farmers. Data were analysed with descriptive statistics, Foster-Greer-Thorbecke (FGT) index and probit regression model. The poverty classification revealed that 35.23% of the farmers were poor and 64.77% were non-poor. The estimated FGT indices for poverty incidence, depth and severity were 0.3523, 0.2669 and 0.0713 respectively. Probit regression analysis showed that emigration status of the farmers at p≤0.05 level of probability had significant positive effect on their poverty status. Other covariates: remittance (p≤0.01), household size (p≤0.01), years of education (p≤0.10), farm income (p≤0.01) and off-farm income (p≤0.01) also had significant effects on the porvety status of the farming households. The study concluded that emigration possess the potential to enhance poverty alleviation among the farming households in the area. Nonetheless, poverty remains a major issue in the area that cannot be overlooked by the government.

description: Experimental transverse momentum spectra of identified particles in p-Pb collisions at 5.02 TeV show many similarities to the corresponding Pb-Pb results, the latter ones usually being interpreted in term of hydrodynamic flow. We analyse these data using EPOS3, an event generator based on a 3D+1 viscous hydrodynamical evolution starting from flux tube initial conditions, which are generated in the Gribov-Regge multiple scattering framework. An individual scattering is referred to as Pomeron, identified with a parton ladder, eventually showing up as flux tubes (or strings). Each parton ladder is composed of a pQCD hard process, plus initial and final state linear parton emission. Nonlinear effects are considered by using saturation scales $Q_{s}$, depending on the energy and the number of participants connected to the Pomeron in question. We compute transverse momentum ($p_{t}$) spectra of pions, kaons, protons, lambdas, and $Ξ$ baryons in p-Pb and p-p scattering, compared to experimental data and many other models. In this way we show in a quantitative fashion that p-Pb data (and even p-p ones) show the typical ``flow effect'' of enhanced particle production at intermediate $p_{t}$ values, more and more visible with increasing hadron mass.

description: We formulate a model of pulsar spin evolution (braking, inclination angle evolution and radiative precession) taking into account the non-rigidity of neutron star rotation. We discuss two simple limiting cases of this model and show that the evolution of the inclination angle substantially depends on the model of crust-core interaction. The non-rigidity of core rotation accelerates the inclination angle evolution and makes all pulsars evolve to the orthogonal state. The size of the effect depends on the amount of differentially rotating matter and mechanism of its interaction with the rest of the star. Since the rapid volution of the inclination angle apparently contradicts the observational data, our results may be used as an additional test for the theories of the cores of neutron stars.

description: This study was conducted to investigate bushmeat trade in Omagwa bushmeat market in Ikwerre Local Government Area of Rivers State. A purposive sampling procedure was adopted in the selection of forty ( 40) respondents. Twenty (20) of them were hunters and Bush trap men and the remaining twenty were wholesalers and retailers. Simple percentage was the analytical tool used for data analysis. The result· revealed that majority of the· participants involved in the bushmeat hunting and bush trap men were of the age bracket between 41-50 years (50)-while the majority of the respondents in wholesalers /retailers were of. the age bracket between 31-40 years (50). The bush meat enterprise is mainly dominated by" men folk and -majority of the respondents were holders of first school leaving certificate. Majority of the hunters and bush trap men realized estimated average revenue of less than N50, 000.00 per annum while majority of the wholesalers and retailers received estimated annual revenue ·of NlOl, 000.00- N200, 000.00. It was discovered that grasscutter meat attracts higher price than other wild species in the study area. The major activities. in bushmeat trade were mainly cleaning, processing and smoke drying of the bushineat products. Among other problems, insufficient supply of the desired species· and constant variation in the price of bushmeat were the major problems faced by the participants. Therefore, there is need to improve the income of the participants- ih bushmeat trade by encouraging the domestication of some of the animal species. This will help to· incfease the revenue earnings· of the respondents ,and also help to prevent the extinction of 'some Wild species in futµre.

Year: 2014
Subjects: subject: Operating Systems (cs.OS)
subject: FOS: Computer and information sciences

description: The main objective of this paper is to present a mechanism of enhanced paging support for the second generation microkernels in the form of explicit support of multi-pager environment for the tasks running in the system. Proposed mechanism is based on the intra-kernel high granularity pagers assignments per virtual address space, which allow efficient and simple dispatching of page faults to the appropriate pagers. The paging is one of the major features of the virtual memory, which is extensively used by advanced operating systems to provide an illusion of elastic memory. Original and present second generation microkernels provide only limited, inflexible and unnatural support for paging. Furthermore, facilities provided by current solutions for multi-pager support on the runtime level introduce an overhead in terms of mode switches and thread context switches which can be significantly reduced. Limited paging support limits the attractiveness of the second generation microkernel based systems use in real-life applications, in which processes usually have concurrent servicing of multiple paging servers. The purpose of this paper is to present a facilities for the efficient and flexible support of multi-pager environments for the second generation microkernels. A comparison of the proposed solution to the present architecture L4 + L4Re has been made and overhead of the page fault handling critical path has been evaluated. Proposed solution is simple enough and provides a natural and flexible support of multi-pager environments for second generation microkernels in efficient way. It introduces a third less overhead in terms of the mode switches and thread context switches in comparison to the present L4 + L4Re solution implemented in the Fiasco.OC.

description: Religion, governance, and politics—as well as related topics such as human rights, justice, and so on—have historically caused many of the world's most significant conflicts, and they continue to do so because these issues are often the most fundamental in the structure of a society. To gain a military advantage, parties to armed conflicts have polluted water, burned crops, cut down forests, poisoned soils, and killed animals over the years. A variety of context factors, particularly socioeconomic conditions, governance, and political factors, interact and play a key role in translating climate change into conflict risks. The present unrest all over the world risks putting more than half of the countries into a crisis of health, economy, and social safety, which is the biggest threat to human civilization. Shockwaves have been felt all over the world as a result of war, inflation, food shortages, and the COVID-19 pandemic's long tail. Financial markets have been extremely volatile since the start of the conflict, and commodity markets are in disarray. In the European Union, the United States, and many other nations, inflation has reached its highest level in decades, with the global conflicts adding to the upward pressure on food and energy prices. However, the global economic slowdown, sharp decline in financial asset values, decline in imports and exports, contraction of industrial production, rise in inflation, decrease in wages, rise in unemployment, collapse of social security, and numerous natural calamities tear down not only the economic sector but also the health sector, which has already been grossly mistreated by the pandemic. War, conflicts, climate change, and pandemics are all contributing to the crisis's escalation, both directly and indirectly. The coexistence of all of these issues may endanger civilization by causing the loss of many basic healthcare facilities such as health system access, vaccination, poison control, coverage health insurance or co-payment policies, health vigilances and surveillances, monitoring of adverse drug reactions, telemedicine support, patient education or awareness programs, newer drug inventions, and allied technological advances and innovations. The security and safety of healthcare facilities, workers, and supply lines remain paramount concerns along with access to health services, technology, and innovation. In a stable socio-political environment and sound economy, any of these facilities in countries or localities would take longer to develop and necessitate government and other allied authority support, IT innovation and protocol advancements, and public adherence to the health system.

description: Festkörperumwandlungen spielen eine wichtige Rolle bei der Herstellung und Verarbeitung von Stählen. Sie sind das effektivste Werkzeug, um die mechanischen Eigenschaften von Stählen zu optimieren. Eine Kette dieser Umwandlungen ist oft an den Verarbeitungsschritten von der Schmelze bis zum Endprodukt beteiligt. Das Ziel dieser Arbeit ist es, eine durchgehende Prozessbeschreibung und Charakterisierung der resultierenden Mikrostrukturen zu realisieren, die eine umfassendere Optimierung dieser Prozesse ermöglichen kann. Um diesem Ziel näher zu kommen, wurden in dieser Arbeit experimentelle und rechnergestützte Werkzeuge erarbeitet. Es wurde ein Experiment zur Hochtemperatur Elektronenrückstreubeugung entwickelt, das es ermöglicht, das Gefüge von Stählen während der Wärmebehandlung durch Rückstreubeugung und einfache Bildgebung abzubilden. Ergänzende Computerprogramme wurden entwickelt, die es ermöglichen, die Rückstreudaten der Mikrostruktur verschiedener Verarbeitungsschritte zu kombinieren, um die mikrostrukturelle Entwicklung quantitativ zu verfolgen. Die Kombination von Rückstreudaten mit Bildgebungssequenzen aus dem Rasterelektronenmikroskop ermöglicht zudem die Charakterisierung hochdynamischer Prozesse, die (noch) nicht durch Elektronenrückstreubeugung charakterisiert werden können. Diese Werkzeuge wurden auf die Ferrit-Austenit-Ferrit- und die Austenit-Martensit-Umwandlung angewendet. Die neuen Methoden, die in dieser Arbeit entwickelt wurden, ermöglichen eine genauere Charakterisierung der Umwandlung und ihrer Produkte: Die Orientierungen der Austenitphase wurden direkt in situ gemessen, anstatt des bisher üblichen Ansatzes bei dem diese mit Rekonstruktionsalgorithmen abgeschätzt werden. Dies ermöglicht erstmals eine quantitative Beschreibung mehrerer Merkmale von Martensit-Mikrostrukturen wie Variantenauswahl, Variantenpaarung und die Martensithabitusebene. Darüber hinaus ermöglicht es die Berechnung von genauen Orientierungsbeziehungen für diese Phasenumwandlungen. Diese umfassendere Charakterisierung trägt dazu bei, mehrere Merkmale dieser Transformationen zu erklären: Die Rolle der verschiedenen Grenzflächen bei der Nukleation von Martensit sowie deren Entstehung und Entwicklung werden geklärt. Zusätzlich wird der Einfluss der Austenitkorngröße auf die Variantenauswahl untersucht und die Ergebnisse verschiedener Austenitrekonstruktionsalgorythmen mit den realen, gemessenen Mikrostrukturen verglichen. Variantenauswahl und Variantenpaarung in vollmartensitischen und zweiphasigen Mikrostrukturen werden verglichen.

description: Sustainable urban development requires providing a healthy and sustainable living envirol}ment with basic services for all and sundry. A healthy and multifunctional urban green structure is one of the basic services to provide. Urban forestry, focusing on the tree-dominated part of urban green space is a strategic integrative, interdisciplinary and participatory approach. Its goal is to sustainably develop the multiple benefits of forests and trees in urban environments. Recently, urban forestry has found broad footings across the world, but its potential for cities and towns in developing countries like Nigeria is yet to be realized. The paper therefore aims at raising awareness, developing state -of- the-art concept and generating new technology and knowledge. It also focused on strengthening institution and policy framework, disseminating information and knowledge and enhancing sustainable urban forestry program for sustainable development in Nigeria.

description: Among the coordinates used to construct a conformal compactification of the Schwarzschild spacetime, none of them simultaneously extend smoothly both through an event horizon and beyond null infinity.To construct such coordinates, instead of starting with the Kruskal-Szekeres coordinates we assume direct analytic transformation between Schwarzschild and compactified coordinates and determine their behavior on the event horizon and at null infinity. We then propose an example of such coordinates and illustrate the way they cover the conformally extended Schwarzschild spacetime as well as their suitability for numerical applications.

description: We study the linear optical absorption of bulk semiconductors in the presence of a homogeneous constant (dc) electric field with an approach suitable for including excitonic effects while working with many-band models. The absorption coefficient is calculated from the time evolution of the interband polarization excited by an optical pulse. We apply the formalism to a numerical calculation for GaAs using a 14-band $\textbf{k} \cdot \textbf{p}$ model, which allows us to properly include interband coupling, and the exchange self-energy to account for the excitonic effects due to the electron-hole interaction. The Coulomb interaction enhances the features of the absorption coefficient captured by the $\textbf{k} \cdot \textbf{p}$ model. We consider the dependence of the enhancement on the strength of the dc field and the polarization of the optical field.

description: We investigate the temperature dependence of the Casimir-Polder interaction in the electrostatic limit. This unusual phenomenon relies on the coupling between a virtual atomic transition and a thermal excitation of surface polariton modes. We first focus on the scenario where a Cs(8P3/2) atom is next to a CaF2 or a BaF2 surface. Our theoretical predictions show a strong temperature dependence of the van der Waals coefficient at experimentally accessible conditions. A series of spectroscopic measurements performed in a specially designed Cs vapour cell containing a CaF2 tube is presented. Our results illustrate the sensitivity of atom surface-interaction experiments to the quality and chemical stability of the surface material and emphasize the need of using more durable materials, such as sapphire. We finally discuss selective reflection experiments on Cs(7D3/2) in an all-sapphire cell that clearly demonstrate a temperature dependent van der Waals coefficient.

description: We present results of the study of a turbulent air flow with a large scale circulation in Rayleigh-Benard rectangular convective cell with a heated bottom wall and a cooled top wall. The mean horizontal velocity of the main roll and the mean vorticity of eddy rings are almost aligned in a large part of the flow. The helicity of the mean flow is quite high, and is the source of turbulent helicity. Since helicity of the mean flow and turbulence is quite large, the flow in Rayleigh-Benard convective cell is well suited to study properties of helical turbulence.

description: We study the environments of low redshift (z < 0.5) quasars based on a large and homogeneous dataset from the Stripe 82 region of the Sloan Digital Sky Survey (SDSS). We have compared the < 1 Mpc scale envi- ronments of 302 quasars that were resolved in our recent study to those of 288 inactive galaxies with closely matched redshifts. Crucially, the lu- minosities of the inactive galaxies and the quasar host galaxies are also closely matched, unlike in most previous studies. The environmental overdensities were studied by measuring the num- ber density of galaxies within a projected distance of 200 kpc to 1 Mpc. The galaxy number density of the quasar environments is comparable to that of the inactive galaxies with similar luminosities, both classes of ob- jects showing significant excess compared to the background galaxy density for distances < 400 kpc. There is no significant dependence of the galaxy number density on redshift, quasar or host galaxy luminosity, black hole mass or radio loudness. This suggests that the fueling and triggering of the nuclear activity is only weakly dependent on the local environment of quasars, and the quasar phase may be a short-lived common phase in the life cycle of all massive galaxies.

description: This study evaluated the technical efficiency of gum arabic production in selected Local Government Areas of Jigawa and Yobe States of Nigeria .. A total of 166 gum arabic farmers were selected through purposive and simple random sampling techniques. Data collected were analysed using stochastic frontier production function analysis. Results of the analysis indicated that variance parameters of the stochastic frontier production function; sigma squared (82 ) and gamma (y) are significantly different from zero at one percent probability level. This indicated a good fit and correctness of the distributional form assumed for the composite eITor term. Gamma indicates that the systematic influences that are unexplained by the production function are the dominant sources of random error and the estimate (0.96) shows the amount of variation resulting from the technical. inefficiencies of the farmers. The variation in fa1mers' output is due to difference in technical efficiency. The mean technical efficiency (TE) of gum Arabic farmers is 0.97. The findings also shows that 46.67 percent of the farmers have TE index below the mean figure while 53.33 percent attaine1 TE of more than the average. Family and hired.labour are statistically significant at 1 percent level,

description: This study examined some aspects of rice production in Kura local government area of Kano State. Structured questionnaires were the main instrument used for data collection from fifty (50) randomly selected respondents. As may be appropriate, potential tools used for anaiyzing the data collected includes descriptive statistics, farm budgeting and production model. The result of the study showed the gross margin of_x0002_N23,04/kg. The result also revealed that the net income for rice production in the study area was N2.43. production was statistically significant at P<0.01, while all other variables were not significant at that level. Rice production constraint identified in the study area include high input cost and limited access to farm credit, inappropriate farmers' management practices, pest and diseases, soil degradation, persistent use of poor quality seed and lack of research and extension support. However, to reap the benefits of rice production in the area, cost of inputs should · be reduced through provision of subsidies and credit facilities should be provided. Effective management practices and support from well trained extension personnel need to be encouraged.

description: Agricultural expansion into tropical and subtropical forests often leads to major social-ecological trade-offs. Yet, despite ever-more detailed information on where deforestation occurs, how agriculture expands into forests remains unclear, which is hampered by a lack of spatially and temporally detailed reconstruction of agricultural expansion. Here, we developed and mapped a novel set of metrics that quantify agricultural frontier processes at unprecedented spatial and temporal detail. Specifically, we first derived consistent annual time series of land-use/cover to, second, describe archetypical patterns of frontier expansion, pertaining to the speed, the diffusion and activity of deforestation, as well as post-deforestation land use. We exemplify this approach for understanding agricultural frontier expansion across the entire South American Chaco (1.1 million km2), a global deforestation hotspot. Our study provides three major insights. First, agricultural expansion has been rampant in the Chaco, with more than 19.3 million ha of woodlands converted between 1985 and 2020, including a surge in deforestation after 2019. Second, land-use trajectories connected to frontier processes have changed in major ways over the 35 year study period we studied, including substantial regional variations. For instance, while ranching expansion drove most of the deforestation in the 1980s and 1990s, cropland expansion dominated during the mid-2000s in Argentina, but not in Paraguay. Similarly, 40% of all areas deforested were initially used for ranching, but later on converted to cropping. Accounting for post-deforestation land-use change is thus needed to properly attribute deforestation and associated environmental impacts, such as carbon emissions or biodiversity loss, to commodities. Finally, we identified major, recurrent frontier types that may be a useful spatial template for land governance to match policies to specific frontier situations. Collectively, our study reveals the diversity of frontier processes and how frontier metrics can capture and structure this diversity to uncover major patterns of human–nature interactions, which can be used to guide spatially-targeted policies.
