Sigil is an e-module creation software that can be used by high school teachers to help provide various teaching materials. However, the teacher's ability use still low where teacher not able apply materials in this e-module. E-modules online learning. One of learning models Guided Discovery Learning (GDL) model. For reason, society service for chemistry who are members Padang Panjang Chemistry...

In a mill spinning coarse cotton the prevalence of byssinosis and other respiratory symptoms, and the F.E.V.1.0, were measured in a group of 29 men and I117 women employed in the winding room. All the men and 95% of the women at risk were included. Dust concentrations, measured with a modified Hexhlet at various work points in the winding room, ranged from i-65 to 6 o5 mg. Jm.3 total dust. Thes...

In this work, the influence of geometric and mechanical properties constitutive layers a Proton Exchange Membrane Fuel Cell (PEMFC) on system performance was investigated. More specifically, study focused internal electrical resistances due to interlayer contacts. Indeed, contact are one main sources ohmic losses in PEMFC therefore require special attention improve efficiency. To end, Design Ex...

High-dose therapy is an effective standard treatment for multiple myeloma patients. Evidence that intermediate-dose therapy improves survival is limited. At diagnosis, about 70% of patients are older than 65. Intermediate-dose regimen is very well tolerated in older patients. In a multicenter study, 194 patients were randomized to receive at diagnosis either conventional chemotherapy (6 courses...

Recently the general Game Description Language (GDL) has been extended so as to cover arbitrary games with incomplete/imperfect information. Learning—without human intervention—to play such games poses a reasoning challenge for general game-playing systems that is much more intricate than in case of complete information games. Action formalisms like the Situation Calculus have been developed fo...

A new species of cloud forest butterfly, Eretris julieta n. sp. is described from a region of south-central Bolivia known as the Elbow of the Andes. It is the southernmost known representative of the genus, hitherto known only from a restricted area of interandean valleys in the department of Santa Cruz. Its affinities with other congeners are evaluated.
