The complement of the Bowditch space in the SL(2,C) character variety

Let ${\mathcal X}$ be the space of type-preserving \SL(2,C) characters of the punctured torus $T$. The Bowditch space ${\mathcal X}_{BQ}$ is the largest open subset of ${\mathcal X}$ on which the mapping class group acts properly discontinuously, this is characterized by two simple conditions called the $BQ$-conditions. In this note, we show that $[\rho]$ is in the interior of the complement of ${\mathcal X}_{BQ}$ if there exists an essential simple closed curve $X$ on $T$ such that $|{\rm tr} \rho(X)|<0.5$.Comment: 6 page

Economic Interdependence and Macroeconomic Coordination

Data indicate that there has been an increasing integration of world financial markets. These have raised fears that countries have become vulnerable to external policies and events. This article discusses the need for policy coordination when there is interdependence among countries. The Philippine macroeconomic and policy coordination is discussed while a two-part recommendation is advocated.economic openness, economic integration

The Transantarctic genus Labena (Hymenoptera: Ichneumonidae: Labenini) in Chile

Labena is a primitive genus known from the Neotropic, Nearctic, Neantarctic, and Australian biogeographic regions. It parasitizes larvae of wood boring beetles in dead twigs and smaller branches of hardwood trees and shrubs. Descriptions are given of 2 new Chilean species: Labena canelensis Porter, from sclerophyll woodland in central Chile, is black with sparse white markings, has a strong tooth at the base of the submetapleural carina, and a short first gastric tergite (2.3-2.6 as long as wide at apex), whereas L. pucon Porter occurs in temperate wet forest of southern Chile and is black with profuse white markings, lacks a submetapleural tooth, and has the first tergite very elongate (4.0-6.2 as long as wide at apex).Labena es un género primitivo conocido de las regiones Neotropical, Neártica, Neantártica, y Australiana y cuyas especies parasitan larvas de coleópteros xilófagos en ramitas y ramas muertas de árboles y arbustos angioespermas. Se describen dos especies nuevas de Chile: Labena canelensis Porter, que habita en el bosque esclerófilo de Chile central, es de color negro con escasos diseños blancos, tiene un gran diente triangular en la base de la carina submetapleural, y el primer tergito gástrico robusto (2.3-2.6 tan largo como ancho en el ápice), mientras L. pucon, que se encuentra en las selvas húmedas del sur, se destaca por ser negra con abundantes diseños blancos, por carecer de un diente submetapleural, y por su primer tergito muy alargado (4.0-6.2 tan largo como ancho en el ápice)

The effect of manganese oxide on the sinterability of hydroxyapatite

The sinterability of manganese oxide (MnO2) doped hydroxyapatite (HA) ranging from 0.05 to 1 wt% was investigated. Green samples were prepared and sintered in air at temperatures ranging from 1000 to 1400 °C. Sintered bodies were characterized to determine the phase stability, grain size, bulk density, hardness, fracture toughness and Young's modulus. XRD analysis revealed that the HA phase stability was not disrupted throughout the sintering regime employed. In general, samples containing less than 0.5 wt% MnO2 and when sintered at lower temperatures exhibited higher mechanical properties than the undoped HA. The study revealed that all the MnO2-doped HA achieved >99% relative density when sintered at 1100–1250 °C as compared to the undoped HA which could only attained highest value of 98.9% at 1150 °C. The addition of 0.05 wt% MnO2 was found to be most beneficial as the samples exhibited the highest hardness of 7.58 GPa and fracture toughness of 1.65 MPam1/2 as compared to 5.72 GPa and 1.22 MPam1/2 for the undoped HA when sintered at 1000 °C. Additionally, it was found that the MnO2-doped samples attained E values above 110 GPa when sintered at temperature as low as 1000 °C if compared to 1050 °C for the undoped HA
