Heaven Ungained
Thomas Smythe
Open Access Library Journal (OALib Journal) , 2016, DOI: 10.4236/oalib.1102214
Abstract: There has been quite a bit of literature on heaven of late. In this paper I state some claims that theistic philosophers and theologians have made about heaven, and make the concept of heaven incoherent. I maintain that it is possible for a rational individual to prefer not to go to heaven. Finally, I argue that it may be preferable for a person of moral integrity to decide that they want to go to hell given the immoral nature of many passages in the Bible.

Abstract: Jordan is blessed with shallow geothermal resources in NE and SE deserts. Jordanian deserts compose more than 70% of the country area. Furthermore, it’s the second vital area in fauna and flora variation after Jordan valley. Geothermal gradient in this area shows high promising future potential. New renewable energy systems installation in Jordan will have a positive environmental and economic contribution to the national bill. Currently, limited geothermal utilizations were evaluated in the Jordanian deserts. Thermal waters in the deserts were used for irrigation only. Six different applications for direct and indirect geothermal applications in Jordanian deserts were suggested and evaluated. Ground source heat pumps for heating and cooling purposes and crops drying were expected to be the most appropriate applications of geothermal energy in the deserts. Geothermal utilizations were investigated regarding their probable impact on local and national economic scale. Therefore, an integrated plan for geothermal applications in Jordan is becoming very essential in the future. It has been found that geothermal energy in Jordanian deserts could be utilized for different applications. Despite of the potential political, technical and financial barriers, exploiting new geothermal utilization in the deserts will contribute to solving socio-economic and environmental problems challenging poor deserts areas.

Abstract: We prove that any (real or complex) analytic horizontally conformal submersion from a three-dimensional conformal manifold M to a two-dimensional conformal manifold N can be, locally, `extended' to a unique harmonic morphism from the heaven space of M to N.
Gene deserts bear fruit

Genome Biology , 2003, DOI: 10.1186/gb-spotlight-20031017-01
Abstract: Nobrega et al. compared human DACH flanking sequences with mouse genomic DNA and by combining additional genome comparison information from distantly related vertebrates such as frog, zebrafish, and pufferfish, narrowed the number of conserved sequences from 1098 to 32. Nine of these were cloned upstream of the mouse heat shock protein 68 minimal promoter driving beta-galactosidase expression. These were used to create transgenic mice whose subsequent development revealed enhancer effects of the elements consistent with DACH endogenous gene expression. Genes flanking the DACH orthologues vary with species, but the adjacent gene deserts were found to be maintained."The size of genomic regions believed to be functionally linked to a particular gene may need to be expanded to take into account the possibility of essential regulatory sequences acting over near-megabase distances," conclude the authors.

Abstract: Walkability has many health, environmental, and economic benefits. That is why web and mobile services have been offering ways of computing walkability scores of individual street segments. Those scores are generally computed from survey data and manual counting (of even trees). However, that is costly, owing to the high time, effort, and financial costs. To partly automate the computation of those scores, we explore the possibility of using the social media data of Flickr and Foursquare to automatically identify safe and walkable streets. We find that unsafe streets tend to be photographed during the day, while walkable streets are tagged with walkability-related keywords. These results open up practical opportunities (for, e.g., room booking services, urban route recommenders, and real-estate sites) and have theoretical implications for researchers who might resort to the use social media data to tackle previously unanswered questions in the area of walkability.
Vortex Streets on a Sphere  [PDF]

Journal of Applied Mathematics , 2011, DOI: 10.1155/2011/712704
Abstract: We consider flows on a spherical surface and use a transformation to transport some well-known periodic two-dimensional vortex streets to that spherical surface to arrive at some new expressions for vortex streets on a sphere. 1. Introduction For fluid flow on a two-dimensional plane, the vorticity at a point is twice the angular rotation. A point vortex is a model of a flow in which the vorticity is zero except at the point itself where the vorticity is infinite, so that there is a nonzero circulation around the point. The study of point vortices on the plane, and other two-dimensional manifolds such as the cylinder, sphere, and torus, has a long history, dating back to the 19th century with Helmholtz [1] initiating the point vortex model and Kirchhoff [2] and Lin [3] formulating it as a Hamiltonian dynamical system. In this paper, we are concerned primarily with vortex streets, which consist of one or more periodic rows of point vortices, the simplest of which is a single infinite row of identical vortices [4]. These have important applications in engineering and geophysics, with a single row having been used to model the quasisteady large-scale vortices arising following the roll-up of a shear layer, and double rows, or von Kármán vortex streets [5], having been used to model the shedding of eddies behind a bluff body. An overview of two-dimensional vortex streets can be found in standard texts on hydrodynamics such as IN [6, 7]. In this paper, we are interested in transporting these well-known vortex streets from the plane to a curved two-dimensional manifold, the surface of a sphere. Flows on a sphere are important because of applications to planetary atmospheres. In his classic monograph, Lamb [6] briefly outlines a method of determining the motion of vortices on a curved manifold and discusses how some of the 19th century work on electrical conduction, such as charge-on-a-sphere problems, by Boltzmann, Kirchhoff, T?pler, and others could be applied to the problem of point vortices on the sphere although Gromeka [8] appears to have been the first to study vortices on a sphere specifically. More recently, the formulation of the motion of vortex streets on curved manifolds has been examined in more detail by Hally [9], with several subsequent studies [10–12] delving more deeply into the formulation of vortex motion on a sphere. A review of some of the work on point vortices on vortices on a sphere can be found in [13]. One interesting thread of research [14–16] has involved using numerical methods, such as contour surgery, to study the motion of

Abstract: Title: Child Labor in the Streets of Bogotá.There are many children working in the streetsof Bogotá. The exact number is unknown andthere is very little information available aboutthis group. Methodology: Descriptive study.Children working in certain streets of Bogotáwere surveyed on Saturday July 19th 2003.Results: A total of 162 children were surveyed,52.5% boys and 47.5% girls; 38.5% youngerthen 5 years and 64.2% older; 61.1% were bythemselves and the rest with an adult; 49.4% werechildren of displaced families and the others werechildren of families from Bogotá. A 33.3% rateof school desertion and a rate of 38.9% lack ofsocial security affiliation were found. The lack ofsocial security affiliation is higher in desplaced families and within this group it is higher in thefamilies that have been living a short period oftime in Bogotá. Discusion: Data suggest a strongrelationship between child labor in the street andthe problem of displaced families; a serious impacton school desertion, and long working hoursexposed to various security, phisical, chemical,ergonomic, and psicosocial risk factors. There arethree groups of children working in the streets ofBogotá: Children of displaced families; childrenthat work in the streets, and children that live inthe streets. Conclusions: Child labor in thestreets of Bogotá is a serious problem, whichrequires attention based on knowledge of causesand the pursuit of effective measures for itseradication.
Multiply-interacting Vortex Streets  [PDF]

Abstract: We investigate the behavior of an infinite array of (reverse) von K'arm'an streets. Our primary motivation is to model the wake dynamics in large fish schools. We ignore the fish and focus on the dynamic interaction of multiple wakes where each wake is modeled as a reverse von K'arm'an street. There exist configurations where the infinite array of vortex streets is in relative equilibrium, that is, the streets move together with the same translational velocity. We examine the topology of the streamline patterns in a frame moving with the same translational velocity as the streets which lends insight into fluid transport through the mid-wake region. Fluid is advected along different paths depending on the distance separating two adjacent streets. Generally, when the distance between the streets is large enough, each street behaves as a single von K'arm'an street and fluid moves globally between two adjacent streets. When the streets get closer to each other, the number of streets that enter into partnership in transporting fluid among themselves increases. This observation motivates a bifurcation analysis which links the distance between streets to the maximum number of streets transporting fluid among themselves. We also show that for short times, the analysis of streamline topologies for the infinite arrays of streets can be expected to set the pattern for the more realistic case of a finite array of truncated streets, which is not in an equilibrium state and its dynamic evolution eventually destroys the exact topological patterns identified in the infinite array case. The problem of fluid transport between adjacent streets may be relevant for understanding the transport of oxygen and nutrients to inner fish in large schools as well as understanding flow barriers to passive locomotion.

Abstract: The development of space technology makes the exposure of organisms and molecules to the space environment possible by using the ESA Biopan and Expose facilities and NASA nanosatellites; the aim is to decipher the origin, evolution and distribution of life on Earth and in the Universe. The study of microbial communities thriving in lithic habitats in cold and hot deserts is gathering appreciation when dealing with the limits of life as we know it, the identification of biosignatures for searching life beyond Earth and the validation of the (litho)-Panspermia theory. Cyanobacteria of the genus Chroococcidiopsis dominate rock-dwelling communities in extreme deserts that are considered terrestrial analogues of Mars, like the Dry Valleys in Antarctica, the Atacama Desert in Chile or the Mojave Desert in California. The extraordinary tolerance of these cyanobacteria towards desiccation, ionizing and UV radiation makes them suitable experimental strains which have been already used in astrobiological experiments and already selected for future space missions. Evidence gained so far supports the use of desert cyanobacteria to develop life support systems and insitu resource utilization for the human space exploration and settlement on the Moon or Mars.
