A common analogy is to compare regionalization to a train. In the classic tradition, you first decide where you want to go and the best way to get there, given available resources and technology. Second, you design the train to fit with the job that lies ahead. Third, you build the train along with the tracks and then get it moving. The other provinces have all built trains and are moving them ...

Bends in volcanic hotspot lineaments, best represented by the large elbow in the Hawaiian-Emperor chain, were thought to directly record changes in plate motion. Several lines of geophysical inquiry now suggest that a change in the locus of upwelling in the mantle induced by mantle dynamics causes bends in hotspot tracks. Inverse modeling suggests that although deep flow near the core-mantle bo...

Compaction of subsoils is a steady increasing challenge as induced by the increase in weight well power field machinery. We performed experiment with two different machinery systems used slurry application. A tractor-trailer combination (TT) was compared to tricycle-like self-propelled machine traction on all three wheels (SP). The maximum wheel load 88 and 114 kN for TT SP treatments, respecti...

The small size of the billions of migrating songbirds commuting between temperate breeding sites and the tropics has long prevented the study of the largest part of their annual cycle outside the breeding grounds. Using light-level loggers (geolocators), we recorded the entire annual migratory cycle of the red-backed shrike Lanius collurio, a trans-equatorial Eurasian-African passerine migrant....

Six cancer resection specimens were thoroughly sectioned and microscopically examined at areas known to have been around 21 gauge fine needle aspiration (FNA) biopsy sites, in an attempt to identify needle tracks. All cases had an interval of not less than 10 days between FNA biopsy and surgery. Foci of tumour were identified histologically in needle tracks from two patients with carcinoma. Thi...

Abstract Over the course of several years, stars trace helical trajectories as they traverse across sky due to combined effects proper motion and parallax. It is well known that gravitational pull an unseen companion can cause deviations these tracks. Several studies have pointed out astrometric mission Gaia will be able identify a slew new exoplanets, stellar binaries, compact object companion...

This paper tests whether the strength of the "spring spike" in birth defects is related to agricultural production and urban location using Texas Birth Defects Registry data for the period 1996-2007. We find evidence of a spike in birth defects among children conceived in the spring and summer, but it is more pronounced in urban non-agricultural counties than in other types of counties. Further...
