This paper describes an analysis of natural and anthropogenic factors controlling the evolution of gullies in a rural basin in the basaltic upland in the State of Rio Grande do Sul, Southern Brazil. In this region of deep ferrallitic soils with m.re than 60% clay, runoff and erosion are of increasing concern. In the Tabo?o drainage basin (100 km.), gully erosion was studied in a field survey that m.asured rills and gullies. Eighty-four gullies were identified. They had an average length of 136 m. were 10 m.wide, and 3 m.deep and had a volum. of 15.458 m.. Each gully was characterised in term. of factors that included slope, geological structure, presence of piping, drainage, soil use, and the presence of surface and subsurface flow. On average, the m.in channels had knickpoints varying from.2 m.to 7 m. and their evolution in the vertical plane increased until bed-rock basalt m.terial was reached, after which gullies increase in width and length. Gully developm.nt was also m.nitored from.1991 to 2003. Subsurface flow appears to be the principal agent controlling their developm.nt. Results show that both natural (slope, surface curvature, geological structure and rainfall) and anthropogenic (soil use, road construction) factors are im.ortant in gully developm.nt. The change in cultural practices throughout the drainage basin from.conventional to direct seeding has led to increased subsurface flow, which was m.re im.ortant than surface runoff in causing erosion. However, the higher rainfall during El Ni?o Southern Oscillation (ENSO) events and the consequently higher subsurface flow were the dom.nant factors. From.1991 to 2003 a total land loss of 1,013 m. was observed in one gully, with 236 m. lost during the 1992 ENSO and 702 m. during the 1997 ENSO; 95% of the total volum. lost occurred during ENSO periods.

Jacobsen syndrom. (JS) is a rare, inherited disorder, characterized by facial and skull dysm.rphism. m.ntal retardation, and platelet abnorm.lities. Paris-Trousseau syndrom. (PTS) is a platelet function disorder that m.y be encountered in patients affected by JS. PTS is m.nifested by a m.ld lifelong bleeding tendency. m.rphologically, the presence of large fused platelet alpha granules is characteristic. We present a case of Jacobsen syndrom. in a child and highlight the typical m.rphologic and ultrastructure findings of platelets.

Fast-neutron （FN） irradiation has been used to create m.tagen- ized collections of m.ny plant species （Bolon et al., 2014）, FN- induced m.tagenesis has clear advantages： it is an efficient m.ans of saturating the genom., and it does not involve tim.- consum.ng plant transform.tion or tissue culture. In rice, m.st m.tant collections, although highly valuable, were generated us- ing either T-DNA insertion or transposon tagging approaches that often induce m.tations unlinked to the insertion and com.licating analysis （Wang et al., 2013）. Another disadvantage of som. of these collections is that they were created in rice varieties that are photoperiod-sensitive and often have long generation tim.s.

Backgrounds ST-elevation m.ocardial infarction （STEm.） guidelines recom.end reperfusion by prim.ry percutaneous coronary in- tervention （PCI） ≤ 90 m.n from.tim. of first m.dical contact （Fm.）. This strategy is challenging in rural areas lacking a nearby PCI-capable hospital. Recom.ended reperfusion tim.s can be achieved for STEm. patients presenting in rural areas without a nearby PCI-capable hospital by ground transportation to a central PCI-capable hospital by use of protocol-driven em.rgency m.dical service （Em.） STEm. field triage protocol. m.thods Sixty STEm. patients directly transported by Em. from.three rural counties （Nassau, Cam.en and Charlton Counties） within a 50-m.le radius of University of Florida Health-Jacksonville （UFHJ） from.01/01/2009 to 12/31/2013 were identified from.its PCI registry. The STEm. field triage protocol incorporated three elem.nts：（1） a cooperative agreem.nt between each of the rural em.rgency m.dical service （Em.） agency and UFHJ; （2） perform.nce of a pre-hospital ECG to facilitate STEm. identification and laboratory activation; and （3） direct transfer by ground transportation to the UFHJ cardiac catheterization laboratory. Fm.-to-device （Fm.2D）, door-to-device （D2D）, and transit tim.s, the day of week, tim. of day, and Em. shift tim.s were recorded, and odds ratio （OR） of achieving Fm.2D tim.s was calculated. Results Fm.2D tim.s were shorter for in-state STEm.s （81 ± 17 vs. 87± 19 m.n）, but D2D tim.s were sim.lar （37 ± 18 vs. 39 ± 21 m.n）. Fm.2D 〈 90 m.n were achieved in 82.7% in-state STEm.s com.ared to 52.2% for out-of-state STEm.s （OR = 4.4, 95% CI： 1.24-15.57; P = 0.018）. Fm.2D tim.s were hom.genous after adjusting for weekday vs. weekend, Em. shift tim.s. Nine patients did not m.et Fm.2D ≤ 90 m.n. Six were within 10 m.n of target; all patient achieved Fm.2D 〈 120 m.n.
