description: Purpose. The main aim of the study was to assess land use land cover change detection (LULCC) from 1990 to 2016 in case of Gibe Sheleko National Park (GSNP), Southwestern Ethiopia. Methodology / approach. Multi-temporal Landsat images and topographic map were acquired in 2016. Field observation using GPS was carried out to generate the ground truth points for image classification and accuracy assessment from December 2016 to June 2017. A total 200 GPS points were purposively collected. The data were analysis by using ERDAS IMGINE 2010 and ArcGIS 10.3.1 software. Supervised classification was carried out to identify the overall land use land cover class. Results. Forest land was rapidly declined with average of 478.5 ha/year for the last 27 years. This revealed that over 66.8 % of forest was diminished from 1990 to 2016 due to anthropogenic factors in the study area. Bush & shrub land was upraised from 12600 ha (31.5 %) to 20600 ha (51.5 %) from 1990 to 2016. Grazing land and bare land was also showed an increment of 3500 ha and 2240 ha with average increment of 134.6 ha/year and 86.5 ha/year respectively from 1990 to 2016. This indicated as most forest land was changed in to bush & shrub land due to human induced factors. Hence, it brings negative effects on the wildlife conservation and socio-economic development. Originality / scientific novelty. This study is orginal research finding by employ above indicated methedology and stated the last 27 years land use land cover change of Gibe Sheleko National Park for fist time.

The study found out that macroeconomic environment has a significant effect on Multinational agricultural enterprises performance and there exists a significant relationship between macroeconomic variables and multinational agricultural enterprises profitability. Originality / scientific novelty. The results of regression analysis revealed that variance in multinational agricultural enterprise performance can be explained by service macroeconomic environment and that there is exist a significant relationship between macroeconomic variables and multinational agricultural enterprise profitability. Therefore, it is important for multinational agricultural enterprises to understand all type of macro factor and their implications on organizational performance of their business. Constant monitoring and conducting environmental scanning of theses macro environment factor should be the concern of multinational agricultural enterprise. Practical value / implications. Based on the above findings, it is recommended that all macroeconomic variables must be well understood and monitored by multinational agricultural enterprises to enhance greater profitability and sustainability. Moreover, multinational agricultural enterprise must demonstrate through their marketing tactics that their effort to sustain local economy and the labor market within a foreign market makes them a valuable contributor to the prosperity of their operating region.

description: A sulfonated magnetic graphene oxide (SMGO) hybrid was successfully synthesized via the nucleophilic substitution reaction and characterized. The removal of chromate by SMGO was investigated. The effects of contact time, initial pH of the solution, and initial chromate concentration on the removal efficiency were investigated. The optimal experimental conditions for enhanced chromate removal were found to be a contact time of 60 min at an initial solution pH of 3. The observed data were fitted with Lagergren pseudo-second-order kinetic model, indicating that chromate adsorption on SMGO was a chemical interaction in nature. The Langmuir model was also used to describe the adsorption processes and the adsorption capacity was found to be 222.22 mg g?1. Thermodynamic studies (DG < 0, DH > 0, DS > 0) revealed that the adsorption process was exothermic and spontaneous. SMGO has potential to be applied several times after desorption in wastewater treatment.

description: Given the benefits of health-related Internet use, we examined whether sociodemographic, medical, and access-related factors predicted this outcome among African American men, a population burdened with health disparities. African American men (n = 329) completed an anonymous survey at a community health fair in 2010; logistic regression was used to identify predictors. Only education (having attended some college or more) predicted health-related Internet use (P < .001). African American men may vary in how they prefer to receive health information; those with less education may need support to engage effectively with health-related Internet use.

description: Purpose. This study focused on the relationship between the increasing population and level of food growth in Nigeria. Methodology / approach. Agriculture’s contribution to GDP was used to proxy food production alongside population growth rate. The ARDL Model was used to estimate both long and short run population-food growth relations over a 35-year period of 1982–2016. The Augmented Dickey-Fuller, Philip Peron and Kwiatkowski-Philips-Schmidt-Shin stationarity tests were carried out to ensure the stationarity of the variables. Results. The results showed that the variables are integrated of mixed order. The Bounds test established cointegration between population growth and food production in Nigeria which validated the Malthusian theory. However, the estimates revealed that population growth had a positive and significant relationship with food growth in both the long and short run. This implies that increase in population is yet to take a negative effect on availability of food against Malthus postulation. Originality / scientific novelty. This study is the only study on the validation of Malthusian theory of population which employed a rigorous means to establish the order of integration of the variables required for the validation test. It also looked at the place of agriculture in the midst of growing population. Practical value / implications. This outcome is a call to intimate the populace on the dangers of population explosion on one hand and on another hand, the government to ensure provision of adaptable and adoptable technology in the agricultural sector to ensure that food production increases as Nigeria is blessed with the land and weather to make this happen.

description: In the absence of efficient collisions, deviations from thermal equilibrium of plasma particle distributions are controlled by the self-generated instabilities. The whistler instability is a notorious example, usually responsible for the regulation of electron temperature anisotropy $A = T_{\perp}/T_\parallel>$ (with $\perp, \parallel$ respective to the magnetic field direction) observed in space plasmas, e.g., solar wind and planetary magnetospheres. Suprathermal electrons present in these environments change the plasma dispersion and stability properties, with expected consequences on the kinetic instabilities and the resulting fluctuations, which, in turn, scatter the electrons and reduce their anisotropy. In order to capture these mutual effects we use a quasilinear kinetic approach and PIC simulations, which provide a comprehensive characterization of the whistler instability under the influence of suprathermal electrons. Analysis is performed for a large variety of plasma conditions, ranging from low-beta plasmas encountered in outer corona or planetary magnetospheres to a high-beta solar wind characteristic to large heliospheric distances. Enhanced by the suprathermal electrons, whistler fluctuations stimulate the relaxation of temperature anisotropy, and this influence of suprathermals increases with plasma beta parameter.

description: We have examined the formation mechanisms of GaN quantum dots (QDs) via annealing of Ga droplets in a nitrogen flux. We consider the temperature and substrate dependence of the size distributions of droplets and QDs, as well as the relative roles of Ga/N diffusivity and GaN nucleation rates on QD formation. We report on two competing mechanisms mediated by Ga surface diffusion, namely QD formation at or away from pre-existing Ga droplets. We discuss the relative roles of nucleation and coarsening dominant growth, as well as the polytype selection, on various substrates. The new insights provide an opportunity for tailoring QD size and polytype distributions for a wide range of III-N semiconductor QDs.

description: Beginning with the acute shortages of 1973-74 and the subsequent shift in the energy pricing .structure, the whole energy area .has been revealed to be immensely complex. The implications of the continuing energy situation portend even further direct and indirect impacts on the national economy. However, many of the analyses of various aspects of the energy situation have necessarily been of a "what if" premise, considering only the direct or first-round effects. This paper reports an effort utilizing a systems approach to analysis of the total domestic energy situation.

Reconceptualising the Law of the Dead by Expanding the Interests of the Living

Subjects: subject: Law
subject: FOS: Law

description: Despite its name, the Australian law of the dead — a term used here to refer to the common law governing the treatment and disposal of the body of a deceased person — has extraordinarily little to do with the recently deceased. Instead, it is traditionally (and narrowly) conceptualised from the perspective of the still-living, with post-death disputes — such as those relating to posthumous interferences with the corpse — being decided by reference to the person who holds the right to possession of the body of the deceased. In contrast, whilst her physical shell continues to play a role at law, from the moment of death onwards the deceased as a person is denied legal existence in the form of rights, interests, or duties. This paper challenges this traditional formulation of the law of the dead by bringing the interests of the deceased to the forefront. It does this by arguing that the law of the dead should be reconceptualised so that the holder of the right to possession of the body of a particular deceased person is considered to experience an expansion of their own personal set of interests; this expansion being equivalent to those interests held by the deceased in relation to her body during her life and continuing into a 'posthumous space' after her death.

On the inclinations of the Jupiter Trojans

description: Jupiter Trojans are are characterized by dark photometric colors, high inclinations and an asymmetry in number of bodies between the two swarms. Different models have been proposed to explain the high inclination of the Trojans and to interpret their relation with the TNOs, but none of them can also satisfactorily explain the asymmetry ratio. Recently it has been found that the asymmetry can arise if Jupiter has migrated inwards by at least a few au during its growth. The asymmetry and the dark colors of the Trojans are natural outcomes of this model, but simulations with massless unperturbed disc particles led to a flat distribution of the Trojan inclinations and a final total mass that was 3-4 orders of magnitude larger than the current one. In our work, we investigate the possible origin of the peculiar inclination distribution of the Trojans in the scenario where Jupiter migrates inwards. We analyze different possibilities: (a) the secular evolution of an initially flat Trojan population, (b) the presence of planetary embryos among the Trojans and (c) capture of the Trojans from a pre-stirred planetesimal population. We find that the secular evolution of the Trojans and Saturn do not affect the Trojan inclinations appreciably, nor is there any significant mass depletion. Embryos embedded in the swarms, in contrast, can stir the Trojan inclinations and can also deplete the swarms efficiently, but it turns out that it is very difficult to get rid of all of the massive bodies. We propose that the disc where Jupiter's core was forming was already excited by the presence of other embryos competing in Jupiter's core's feeding zone. We show that the trapped Trojans preserve their high inclination through the gas phase of the disc and that Saturn's perturbations are more effective on highly inclined Trojans, leading to a lower capture efficiency and to a substantial depletion of the swarms.

description: Epsilon near zero modes offer extreme field enhancement that can be utilized for developing enhanced sensing schemes. However, demonstrations of enhanced spectroscopies have largely exploited surface polaritons, mostly due to the challenges of coupling a vibrational transition to volume-confined epsilon near zero modes. Here we fabricate high aspect ratio gratings (up to 24.8 um height with greater than 5 μm pitch) of 4H-SiC, with resonant modes that couple to transverse magnetic and transverse electric incident fields. These correspond to metal-insulator-metal waveguide modes propagating downwards into the substrate. The cavity formed by the finite length of the waveguide allows for strong absorption of incident infrared light (>80%) with Q factors in excess of 90, including an epsilon near zero waveguide mode with εeff=0.0574+0.008i. The localization of the electromagnetic fields within the gap between the grating teeth suggests an opportunity to realize a new platform for studying vibrational coupling in liquid environments, with potential opportunities for enhanced spectroscopies. We show that these modes are supported in anhydrous and aqueous environments, and that high aspect ratio gratings coherently couple to the vibrational transition in the surrounding liquid.

description: In the effervescent and politically charged New York of the late 1960s and early 1970s, a group of migrant artists from Latin America produced neo avant-garde artworks that challenged the reigning formalism and purported autonomy of the art object while contributing discussions on identity. Departing with a survey on how they conformed a community through political and artistic associations, this dissertation then focuses on works by Luis Camnitzer, Jaime Davidovich, Juan Downey, Leandro Katz, Alberto Greco, Marta Minujín, Liliana Porter, and Hélio Oiticica; to highlight how topics of migration, exchange, internationalism, violence, exile, and nostalgia appear in their happenings, environments and conceptual art. Responding to their cross-cultural condition and Cold War geopolitics, they addressed national mythologies, uneven power relations, and hemispheric affairs. Their contributions revealed a more diverse and cosmopolitan scene than typically portrayed in the historiography of postwar American art. Actively participating in experimental artistic movements, including minimalism, conceptualism, and Fluxus, they challenged folklorist understandings of the region’s artistic production promoted by most US cultural institutions and the art market, proposing an alternative understanding of Latin American art. For these artists, “Latin American” was not a label they necessarily identified with before arriving in New York, but, rather, one made relevant by shared experiences and a newfound sense of kinship. In search of new moorings, they recurred to performative dimensions of identity construction to imagine a community for themselves. Inhabiting the de facto capital of the West, they remained conscious of their status as immigrants from the South. Diversifying the city’s artistic life, they helped shape New York into the global art center it is today.

In particular we show how the dilution of a fluid due to the expansion of the universe can be compensated by an increase of the effective coupling of that fluid to gravity in the presence of a potential which acts to reduce the size of the compact space. We estimate how much cosmic acceleration can be obtained in such a model and comment on the difficulties faced in finding an appropriate potential.

description: Digital Earth was born with the aim of replicating the real world within the digital world. Many efforts have been made to observe and sense the Earth, both from space and by using in situ sensors. Focusing on the latter, advances in Digital Earth have established vital bridges to exploit these sensors and their networks by taking location as a key element. The current era of connectivity envisions that everything is connected to everything. The concept of the Internet of Things emerged as a holistic proposal to enable an ecosystem of varied, heterogeneous networked objects and devices to speak and interact with each other. To make the IoT ecosystem a reality, it is necessary to understand the electronic components, communication protocols, real-time analysis techniques, and the location of the objects and devices. The IoT ecosystem and the Digital Earth jointly form interrelated infrastructures for addressing modern pressing issues and complex challenges. In this chapter, we explore the synergies and frictions in establishing an efficient and permanent collaboration between the two infrastructures, in order to adequately address multidisciplinary and increasingly complex real-world problems. Although there are still some pending issues, the identified synergies generate optimism for a true collaboration between the Internet of Things and the Digital Earth.

description: We revisit the hybrid inflation model gauged by $U(1)_{B-L}$ extension of the Minimal Supersymmetric Standard Model (MSSM) in a no-scale background. Considering a single predictive framework, we study inflation, leptogenesis, gavitino cosmology, and the stochastic background of gravitational waves produced by metastable cosmic strings. The spontaneous breaking of $U(1)_{B-L}$ at the end of inflation produces a network of metastable cosmic strings while, the interaction between $U(1)_{B-L}$ Higgs field and the neutrinos generate heavy Majorana masses for the right-handed neutrinos. The heavy Majorana masses explain the tiny neutrino masses via the seesaw mechanism, a realistic scenario for reheating and non-thermal leptogenesis. We show that a successful non-thermal leptogenesis and a stable gravitino as a dark matter candidate can be achieved for a wide range of reheating temperatures and $U(1)_{B-L}$ symmetry breaking scales. The possibility of realizing metastable cosmic strings in a grand unified theory (GUT) setup is briefly discussed. We find that a successful reheating with non-thermal leptogenesis and gravitino dark matter restrict the allowed values of string tension to a narrow range $10^{-9} \lesssim Gμ_{CS} \lesssim 8 \times 10^{-6}$, predicting a stochastic gravitational-wave background that lies within the 1-$σ$ bounds of the recent NANOGrav 12.5-yr data, as well as within the sensitivity bounds of future GW experiments.

description: In this paper we define 2-vector bundles as suitable bundles of 2-vector spaces over a base space, and compare the resulting 2-K-theory with the algebraic K-theory spectrum K(V) of the 2-category of 2-vector spaces, as well as the algebraic K-theory spectrum K(ku) of the connective topological K-theory spectrum ku. We explain how K(ku) detects v_2-periodic phenomena in stable homotopy theory, and as such is a form of elliptic cohomology.

description: The process of baryon number transfer due to string junction propagation in rapidity is considered. It has a significant effect in the net baryon production in $pp$ collisions at mid-rapidities and an even larger effect in the forward hemisphere in the cases of $πp$ and $γp$ interactions. The results of numerical calculations in the framework of the Quark-Gluon String Model are in reasonable agreement with the data with the same parameter values for different energies.

description: Objective: The objective of this scoping review is to describe the uses of the 10-item clinical activity score (CAS10), as well as the cut-off points used. Introduction: The CAS instrument was created by Mourits for thyroid ophthalmopathy, is still recommended in the most recent clinical practice guidelines. The CAS10 has been widely used for assessing the activity of Graves' ophthalmopathy and the CAS7 for measure response to treatment. Both Mourits documents are cited interchangeably and often erroneously to refer to CAS7. The development of a scoping review on this topic is fundamental to clarify the gaps in knowledge that are recognized when citing the scale, considering that no current or underway scoping reviews on the topic were identified. Inclusion criteria: All the investigations where patients were evaluated using the CAS10 will be included. The articles where the number of CAS items was not specified or if the number of items was different from 10, they were eliminated. Studies from all continents were included equally. Methods: The electronic search will be carried out in electronic databases like PubMed and Scopus until September 25, 2021, restricting itself to the English and Spanish languages. Primary studies that had used the CAS10 from Mourits will be searched using the “citing by” tool between 1989- and 1997-year publication. The data will be extracted in a Microsoft Excel sheet independently by two researchers to later be compared and avoid typing bias. The selected data will be presented in diagrammatic and tabular forms.

description: In this survey, we review the classical Hamilton Jacobi theory from a geometric point of view in different geometric backgrounds. We propose a Hamilton Jacobi equation for different geometric structures attending to one particular characterization: whether they fulfill the Jacobi and Leibniz identities simultaneously, or if at least they satisfy one of them. In this regard, we review the case of time dependent and dissipative physical systems as systems that fulfill the Jacobi identity but not the Leibnitz identity. Furthermore, we review the contact evolution Hamilton Jacobi theory as a split off the regular contact geometry, and that actually satisfies the Leibniz rule instead of Jacobi. Furthermore, we include a novel result, which is the Hamilton-Jacobi equation for conformal Hamiltonian vector fields as a generalization of the well known Hamilton Jacobi on a symplectic manifold, that is retrieved in the case of a zero conformal factor. The interest of a geometric Hamilton Jacobi equation is the primordial observation that if a Hamiltonian vector field can be projected into a configuration manifold by means of a 1-form dW, then the integral curves of the projected vector field can be transformed into integral curves of the Hamiltonian vector field provided that W is a solution of the Hamilton-Jacobi equation. Geometrically, the solution of the Hamilton Jacobi equation plays the role of a Lagrangian submanifold of a certain bundle. Exploiting these features in different geometric scenarios we propose a geometric theory for multiple physical systems depending on the fundamental identities that their dynamic satisfies. Different examples are pictured to reflect the results provided, being all of them new, except for one that is reassessment of a previously considered example.
Magnetic collapse of a neutron gas: Can magnetars indeed be formed

description: A relativistic degenerate neutron gas in equilibrium with a background of electrons and protons in a magnetic field exerts its pressure anisotropically, having a smaller value perpendicular than along the magnetic field. For critical fields the magnetic pressure may produce the vanishing of the equatorial pressure of the neutron gas. Taking it as a model for neutron stars, the outcome could be a transverse collapse of the star. This fixes a limit to the fields to be observable in stable neutron star pulsars as a function of their density. The final structure left over after the implosion might be a mixed phase of nucleons and meson condensate, a strange star, or a highly distorted black hole or black "cigar", but no any magnetar, if viewed as a super strongly magnetized neutron star. However, we do not exclude the possibility of a supersotrong magnetic fields arising in supernova explosions which lead directly to strange stars. In other words, if any magnetars exist, they cannot be neutron stars.

description: The thermodynamical partition function of the Duffin-Kemmer-Petiau theory is evaluated using the imaginary-time formalism of quantum field theory at finite temperature and path integral methods. The DKP partition function displays two features: (i) full equivalence with the partition function for charged scalar particles and charged massive spin 1 particles; and (ii) the zero mode sector which is essential to reproduce the well-known relativistic Bose-Einstein condensation for both theories.

description: It is known that nanoscale precipitates strongly affect the precipitation hardening of structural materials. In this study, we report the precipitation kinetics and thermostability of Cu-rich and NiAl nanoprecipitates in nanostructured steels with Mo additions. Atom probe tomography and first-principles calculations revealed that the addition of Mo effectively decreased the diffusion coefficients of Cu, Ni and Al atoms, leading to the change in the precipitation mechanisms from NiAl prior-precipitation with an instantaneous-nucleation mechanism to the Cu prior-precipitation with a continuous-nucleation mechanism. The decreased diffusion coefficient significantly improves the thermostability of nanoprecipitates and strongly enhances the strength of the nanostructured steels. The precipitation mechanisms and thermostability of nanoscale precipitates in nanostructured steels are strongly dependent on the diffusion coefficient of elements, which can be effectively tuned by alloying with Mo additions.
