Road infrastructure developments in rural Papua New Guinea (PNG) have not picked up pace due to mountainous and difficult geographical landscape. Hence road accessibility Salt Nomane Karimui (SNK) District of Simbu province is emerged as a serious concern particularly with regard impact poor mobility on agricultural produce ability access public amenities. Governing agencies plans place for con...

We analyze the information that can be retrieved from tracking parameters produced by an innovative wearable eye tracker. The latter is based on a permanent-magnet marked corneal lens and array of magnetoresistive detectors measure magnetostatic field in several positions proximity. demonstrate that, despite missing due to axial symmetry measured field, physiological constraints or measurement ...

The adjacency matrix is the most fundamental and intuitive object in graph analysis that useful not only mathematically but also for visualizing structures of graphs. Because appearance an critically affected by ordering rows columns, or vertex ordering, statistical assessment graphs together with their sequences important identifying characteristic In this paper, we propose a hypothesis testin...

Hydrothermal convection of pore water with a temperature-dependent viscosity within a permeable, internally heated, moderately thin spherical shell is investigated by both a perturbation analysis and a direct numerical simulation. The analysis and simulation are mainly focused on a thin spherical shell in that convective instabilities are characterized by the spherical harmonic degree l=6 with ...

We want to find an approximate shortest path for a point robot moving in a planar subdivision. Each face of the subdivision is associated with a convex distance function that has the following property: its unit disk contains a unit Euclidean disk, and is contained in a Euclidean disk with radius ρ. Obstacles are allowed, so there can be regions that the robot is not allowed to enter. We give a...

The moderately halophilic heterotrophic aerobic bacteria form a diverse group of microorganisms. The property of halophilism is widespread within the bacterial domain. Bacterial halophiles are abundant in environments such as salt lakes, saline soils, and salted food products. Most species keep their intracellular ionic concentrations at low levels while synthesizing or accumulating organic sol...

By in vitro methods, five aminoglycoside antibiotics (amikacin, kanamycin, gentamicin, tobramycin, and netilmicin) were shown to produce modest changes in granulocyte adherence (increase) and migration (decrease) and no change in phagocytosis or nitroblue tetrazolium reduction.

AIMS Our aim was to evaluate the effect of acid and alkaline pH on chickpea rhizobia, and on chickpea-rhizobia symbiosis. METHODS AND RESULTS Forty-seven rhizobia isolates obtained from 12 Portuguese soils were grown at pH 5, 7 and 9. Among these, 26 grew more at pH 5 than at 7, suggesting the existence of acidophiles. All isolates were identified as mesorhizobia by 16S rDNA partial sequence ...

We suggest the use of moderately superheated liquids in the form of superheated droplet detectors for a new type of neutralino search experiment. The advantage of this method for Dark Matter detection is, that the detector material is cheap, readily available and that it is easily possible to fabricate a large mass detector. Moreover the detector can be made ”background blind”, i.e. exclusively...

We give an algorithm to find the intersection of two subcosets in the symmetric group Sn in time exp (O( √ n log n)).
