Three New Earthworms of the Genus Amynthas (Clitellata: Megascolecidae) from Nam Ha NPA, Laos
Yong Hong,Samuel W. James,Khamla Inkhavilay 한국동물분류학회 2014 Animal Systematics, Evolution and Diversity Vol.30 No.2
Three new species of Amynthas (Clitellata: Megascolecidae) were discovered in the Nam Ha National Protected Area (NPA) of Laos. These are Amynthas namhaensis sp. nov., Amynthas vanhi sp. nov., and Amynthas angtanensis sp. nov. Amynthas namhaensis sp. nov. and Amynthas vanhi sp. nov. are athecal, with male pores 0.14-0.17 and 0.17-0.19 circumference apart ventrally, respectively. Amynthas angtanensis sp. nov. has four pairs of spermathecal pores on 4/5-7/8, with male pores very closely set at 0.07-0.1 circumference apart. Descriptions of the new species are provided, including illustrations of the ventral view, intestinal caeca, and spermathecae.
A New Species of the Genus Pithemera(Oligochaeta: Megascolecidae) from Namat NBCA, Laos
Yong Hong,Samuel W. James,Khamla Inkhavilay 한국동물분류학회 2008 Animal Systematics, Evolution and Diversity Vol.24 No.2
As a result of a taxonomic study on the earthworm material collected from Namat National Biodiversity Conservation Area(NBCA), Hoaphane Province, Laos, a new species, Pithemera viengthongensis sp. nov. is described from near Namchong river, Viengthong district. The new species bearing two pairs of spermathecal pores in 7/8, 8/9 is not assignable to any other species of Pithemera as defined by Sims and Easton(1972). In the new species, the male pore region has kidney-shaped pads extending between ⅩVII-19/20, the male pores and spermathecal pores are 0.31 circumference apart, and genital papillae are lacking. The ventral view of anterior body region and the spermathecae are illustrated.
Simulation of Clutch Actuation System for Commercial Vehicle

Generally, a method of a hysteresis loop is used to show the property of the clutch system in the design process. This represents the load by a pedal travel which is a useful data for designing a vehicle for the comfort of the driver. Transfer torque of manual shift gear types for heavy duty vehicles is too high. Therefore unlike passenger car air pressure is added to the clutch system in addition to the fluid pressure. In this case it is hard to predict nonlinear element to control the hysteresis because of the addition of the components. In this paper theoretical model of the system components involving variables such as mass, stiffness and damping is developed and simulated. The results of the actual test of the clutch system are compared with simulation.

Three new species of the earthworm genus Amynthas Kinberg, 1867 are described from Nam Phouin, Xayabouli Province, Laos. Amynthas appelhofae sp. nov. has spermathecal pores paired in 7/8/9 at 7th setal lines 0.22–0.29 circumference apart ventrally, simple intestinal caeca, and first dorsal pores in 4/5. Amynthas feakinsi sp. nov. has spermathecal pores paired in 5/6/7 at 17th setal lines, 0.30–0.35 circumference apart ventrally, manicate intestinal caeca, and first dorsal pores in 12/13. Amynthas nathanohlfsi sp. nov. has spermathecal pores paired in 6/7–8/9 at 2nd setal lines, 0.02–0.04 circumference apart ventrally, a single broad oval male porophore, and hearts only in segments XII and XIII.
