A synthesis of well logs was carried out and drilling mud weight data were analyzed to figure out anomalous high fluid pressure within the Triassic evaporitic cap rock (the Dashtak formation) and study its impact on the geometry of anticlinal traps in the gas rich Gavbandi province located in the southeast part of the Zagros Mountains. The results indicated that the location of anticlinal traps...

Leg injuries of coyotes {Canis latrans) captured in standard No. 3 Soft Catch traps were compared with those captured in the same trap type modified with two additional coil springs. One hundred thirteen coyotes were trapped in southern California in conjunction with livestock predator control operations, 53 in standard traps, and 60 in modified traps. Observed injuries were similar in both tra...

During the summer of 2001, field studies were performed to evaluate the effects of carbon dioxide (CO2) and 1-octen-3-ol (octenol) on the ability to collect Aedes albopictus with Centers for Disease Control (CDC) Fay-Prince traps. Results from these studies indicated that Ae. albopictus is significantly more attracted to CO2- or CO2 + octenol-baited CDC Fay-Prince traps than unbaited or octenol...

We introduce a concept of accountability traps. Two conditions characterize an accountability trap: (i) a society is caught in a self-reinforcing pattern of behavior with low accountability and (ii) within the same set of institutions, there is another selfreinforcing pattern of behavior with greater accountability and higher voter welfare. We show that a canonical model of elections is consist...

Despite the considerable amount of research devoted to economic growth and development, economists have not yet discovered how to make poor countries rich. As a result, poverty remains the common experience of billions. One half of the world’s people live on less than $2 per day. One fifth live on less than $1. 1 If modern production technologies are essentially free for the taking, then why is...

The photodarkening (PD) mechanisms of ytterbium-doped silica optical fibers have still not been elucidated, although hardening routes have been proposed. Most basic questions are still under debate about the assignment of the darkening excitation bands into the UV range, the nature of absorbing centers (photoionized centers or trapped carriers?), or of traps accepting photo-released carriers (e...

Multiple-beam optical traps facilitate advanced trapping geometries and exciting discoveries. However, the increased manipulation capabilities come at the price of more challenging position and force detection. Due to unrivaled bandwidth and resolution, photodiode based detection is preferred over camera based detection in most single/dual-beam optical traps assays. However, it has not been tri...

We present the initial results of a cytometer that uses an array of extruded high-performance dielectrophoretic traps to capture, hold, and selectively release multiple single bioparticles. We have fabricated small arrays of traps and demonstrated single-bead and single-cell trapping, electrically switched bead release from single traps, fluorescence microscopy of trapped viable single cells, a...

We present a simple Fokker-Planck model for the evolution of the number of atoms and the spatial distribution in a CO2 laser trap which is loaded from a magneto-optical trap ~MOT!. Deep CO2 laser traps can achieve very high densities, but reach equilibrium slowly compared to shallow traps. Equilibrium times range from milliseconds for shallow traps to seconds in traps which are deep compared to...

Introduction Tumor necrosis factor receptor-associated periodic syndrome (TRAPS) is an autoinflammatory disease inherited in an autosomal dominant fashion. TRAPS develops secondary to mutations in TNFRSF1A. Associated symptoms include periodic attacks of peritonitis, constipation, arthritis in large joints, arthralgia, migratory rash with underlying myalgia, periorbital edema, conjunctivitis, s...
