BACKGROUND Hollow earmolds have become a popular type of earmold used in thin-tube, microsize hearing aid fittings. It is desirable for clinicians to be familiar with their characteristics and limitations. PURPOSE This investigation compared the effects of vent diameter between a traditional solid earmold and a hollow earmold that is used in modern thin-tube hearing aid fittings. RESEARCH D...
Influence of a vent hood at the exit of exhaust flue gas and flue baffles in the firetube on the temperature and flow fields of a gas tank water heater, as well as thestructure and amount of heat transferred to the water tank has been studiednumerically using two-dimensional steady state finite element simulation.Observations show that without a vent hood, there is a downward gas flow in theflu...
There are still notable gaps regarding the detailed distribution of microorganisms between and within insular habitats such as deep-sea hydrothermal vents. This study investigates the community composition of black smoker vent microorganisms in the Southern Hemisphere, and changes thereof along a spatial and chemical gradient ranging from the vent plume to surrounding waters. We sampled two hyd...
Many investigations have recently been performed on return vent height and indicate that having 1.3 m distance from the floor is the optimized height for it. In this article, the effect of distance between opening diffuser and return vent on air quality, thermal comfort and energy saving was investigated. According to the results, by increasing the distance between opening and return vent up to...
In the present study seed-born fungi in choy sum (Brassica Chinensis Var. Parchinensis) was detected through a near-infrared reflectance spectroscopy–based nondestructive technique. Four common species of seed-borne namely, Penicillium decumbens, namyslowskii, Lichtheimia corymbifera, and Aspergillus niger were found to grow southern China. A novel finding that P. decumbens had greatest inhibit...
جنس arnebia forssk. از خانواده boraginaceae باحدود 25 گونه گیاهی از شمال آفریقا تا آسیای مرکزی و هیمالایا پراکنش دارد. در ایران 8 گونه از آن گزارش شده که از این تعداد 1 گونه اندمیک ایران است. یکی از مشکلات موجود برای گروه بندی گونه های این جنس وجود پلی مورفیسم و کمبود صفات تاکسونومیک است. در این مطالعه سعی شد از صفات تشریحی و بیوشیمیایی به همراه صفات مورفولوژیک در ارائه الگوی ثابت و صحیح برای ش...
The effects of naturally acidified seawater on shell traits were quantified through the comparison of dove snails (Family: Columbellidae) Anachis misera from vent environments with Euplica sp. from non-vent sites in northeastern Taiwan. Samples of A. misera were collected around a shallow vent (24.8341 N, 121.96191 E), which included the east, south, southwest, and northwest sites. An absence o...
Sedimented hydrothermal vents, where hot, mineral-rich water flows through sediment, are poorly understood globally, both in their distribution and the ecology of individual vent fields. We explored macrofaunal community ecology at a sediment-hosted hydrothermal vent in the Southern Ocean. This is the first such study of these ecosystems outside of the Pacific and the furthest south (62S) of an...
Morphological variation in three rarely collected European species of the genus Lasiochernes Beier, 1932 is thoroughly examined in the present study. Detailed descriptions of previously ignored morphological characters of Lasiochernes cretonatus Henderickx, 1998, Lasiochernes jonicus (Beier, 1929) and Lasiochernes pilosus (Ellingsen, 1910) are presented. The female of Lasiochernes cretonatus an...
In a loamy clay soil of the Colombian Altillanura, animal production legumes Centrosema molle accession CIAT 15160, C. macrocarpum 15799 and Grona heterocarpa subsp. ovalifolia (syn. Desmodium ovalifolium) cv. Maquenque, in association with Urochloa decumbens Brachiaria decumbens) Decumbens, was evaluated under rotational grazing zebu Brahman steers. The experiment established native savanna ar...
