The Global River Discharge (RivDIS) data set contains monthly discharge measurements for 1018 stations located throughout the world. The period of record varies widely from station to station, with a mean of 21.5 years. These data were digitized from published UNESCO archives by Charles Voromarty, Balaze Fekete, and B.A. Tucker of the Complex Systems Research Center (CSRC) at the University of New Hampshire. River discharge is typically measured through the use of a rating curve that relates local water level height to discharge. This rating curve is used to estimate discharge from the observed water level. The rating curves are periodically rechecked and recalibrated through on-site measurement of discharge and river stage.

O estágio pedagógico proporciona uma oportunidade de crescimento pessoal e profissional, sendo uma etapa fundamental para a formação de um professor. O presente relatório, realizado no âmbito do Mestrado em Ensino da Biologia e da Geologia no 3º Ciclo do Ensino Básico e no Ensino Secundário, descreve o estágio pedagógico concretizado na Escola Secundária Jaime Moniz, no ano letivo de 2012/2013. O relatório teve por objetivo descrever, analisar e refletir sobre todas as atividades realizadas, as práticas vividas e as competências adquiridas e desenvolvidas ao longo da Prática de Ensino Supervisionada. Este relatório é uma síntese das atividades desenvolvidas nos seguintes domínios: Prática de Ensino Supervisionada, Atividades de Integração no Meio Escolar, Atividades de Intervenção na Comunidade Escolar e Atividades de Natureza Científico-Pedagógica. O trabalho desenvolvido ao longo do estágio e durante a escrita do relatório revelou-se um tempo importante para vivenciar e refletir a realidade do quotidiano da profissão professor e para compreender os desafios da mesma. Das várias componentes do estágio, destacou-se a prática letiva, porque foi em torno dela que decorreu o estágio, tendo o professor estagiário, através da mesma, tido a oportunidade de evoluir pessoal e profissionalmente. As atividades e as reflexões realizadas permitiram adquirir conhecimentos e competências imprescindíveis para um profissional do ensino e contribuíram para a formação integral do professor estagiário.

Pakistan's knitwear exports had been struggling since the quota phase-out until 2009. A particular feature of Pakistan's garment industry is that hiring more male sewing operators at piece rates. Recently, a few surviving knitwear factories have adopted a strategy of shifting from male piece-rate operators to salaried female operators. In Pakistan, female participation in general workforce is very limited and hiring salaried female operators requires management effort and expertise. However, even in the factories with such management skills, household factors prevent females from working outside because Pakistani culture disrespects women working in factories. Our survey reveals that financial motives compel female household members to work outside their homes and that female operators contribute substantially to their households' finances.

This proposed project aims to design a Model of Public Policy for R&D &I to lead, coordinate and direct the Regional Innovation System (RIS) in support of the SMI sector. The case study of the Bolivar State, Venezuela, is analyzed. The project represents a no- experimental research of projective type and is divided into two parts. In the first one, the current state of the SRI and its relationship with the SMIs is diagnosed, evaluated and described. In the second part, a model of public policy for R&D&I is designed and proposed in order to strengthen the capacity for innovation in SMIs.

Gold nanoparticles supported on a polyacrylamide containing a phosphinite ligand have been synthesized and characterized using different techniques such as TEM, SEM, EDX, XPS, and solid UV analyses. The new material was successfully applied as a heterogeneous catalyst for the three-component A3 coupling of amines, aldehydes, and alkynes to give propargylamines. Reactions are performed in neat water at 80 °C with only 0.05 mol% catalyst loading. The heterogeneous catalyst is recyclable during seven consecutive runs with small decrease in activity.

This single page handwritten letter was sent from Lemuel Shaw to his mother, Susanna, during his freshman year at Harvard. In the letter, he requested that his mother wash and return his dirty laundry and send him clothes, including a pair of overalls, some neck-handkerchiefs, and a new hat. Shaw also asked for money to be sent to pay off his debt of $21.25 to Mr. Richard Hunnewell for board and rent, $18.93 for the previous quarter’s bill, and $1.15 for Mr. Timothy Alden, the College Butler.

Numerous structural features occur in the Leg 128 cores from the Japan Sea. They include (1) gravity-induced structures such as slump folds, (2) dewatering structures comprising several sets of veins, and (3) larger faults and veins developed in the volcanic basement of the Yamato Basin as well as in the sedimentary rocks of the Oki Ridge and Kita-Yamato Trough. Gravity-induced structures, mainly slumps and associated faults, suggest the existence of paleoslopes and the dominance of gravitational tectonics during the early and middle Miocene, at the Pliocene/Pleistocene boundary, and during the Quaternary. Several types of mud-filled veins having various shapes were observed. These are especially abundant in the middle Miocene siliceous claystones and porcellanites from the Kita-Yamato Trough. They have been interpreted as dewatering conduits that formed preferentially in highly porous, water-saturated diatomaceous muds on a slope, because of episodic loss of sediment strength, collapse of the sediment framework, and consequent fluid migration. The central part of the vein serves once as a fluid conduit, whereas the transition between conduit-controlled and intergranular flow occurs at the branching extremities, with concentration of fines. The likely trigger responsible for the strength loss is seismic activity. Development of these veins, spatially and chronologically linked to small normal microfaults, implies an extensional regime having layer-parallel extension and a local bedding-parallel shear couple, probably the result of gravitational gliding. The brittle fractures found in Yamato Basin basement Hole 794D cores comprise joints, faults, and veins filled with chlorite-saponite, saponite, and calcite. They suggest a likely transpressive to transtensional regime around the early Miocene/ middle Miocene boundary, with a north-northeast-south-southwest compression alternating with a west-northwest-eastsoutheast extension. The faults from Site 799 cores on the Yamato Rise exhibit a prominent early Miocene-middle Miocene extensional environment, a late Miocene-early Pliocene phase of normal and strike-slip faulting, and a final phase that began during the latest Pliocene. Site 798, on the Oki Ridge, reveals faults that recorded a consistent extensional tectonic regime from Pliocene to the Holocene. These data support the pull-apart kinematic model for early Miocene-middle Miocene time, as regarding the stress regime deduced from the Yamato Basin basement fractures. The recent compression known in the eastern margin of the Japan Sea was not documented by compressive structures at any site. The late Miocene-early Pliocene faulting phase corresponds to a major and general reorganization of the stress distribution in the arc area. Evidence for rapid and main subsidence and synsedimentary extension of the Yamato Basin and Yamato Rise areas between 20 and 15 Ma, and the concomitant rotation of southwest Japan, raise the question of links between this opening and the Shimanto Belt collision in southwest Japan, between the arc and the Philippine Sea Plate.
