A new isopod genus is described from the Canada Basin, Nymphodora gen. nov. The type species of the genus, Nymphodora fletcheri (Paul & George, 1975) comb. nov., was first described as Desmosomatidae in the genus Mirabilicoxa and then later assigned to Chelibranchus by Kussakin (1999). However, the species bears characters with a greater affinity to Nannoniscidae, such as a bulbous terminal art...

Male urethral diverticula are rare and can be congenital or acquired. We report a case of acquired urethral diverticulum presenting as a scrotal mass in a paraplegic male. On physical examination, the scrotal mass mimicked a primary intrascrotal lesion. However, on retrograde urethrography, the correct diagnosis was made. The patient had a small incontinent spastic bladder with a history of pro...

One of the main goals ship design process is reduction total resistance, which nowadays even more highlighted due to increasingly stringent rules related energy efficiency. In this paper, investigation impact bow on resistance a yacht carried out for three models by towing tank tests and numerical simulations. The verification validation studies are performed, satisfactory agreement achieved. A...

Spiders of the genus Cybaeus L. Koch, 1868 exhibit two major centers diversity: Western North America and Japan. Several Japanese possess an elongated embolus in male palp tubular spermathecae female genitalia. Here we describe koikei sp. nov. from central Honshu, Japan, which has unelongated bulbous spermathecae. Phylogenetic analyses using nuclear mitochondrial gene markers clearly support mo...

A new genus and species of digamasellid mites is described based on adult females males. Bulbolaelaps bossei n. gen., sp. was collected from the fruiting bodies gilled fungi a tree trunk in Zanjan province, Iran. The can be distinguished other genera Digamasellidae by having bulbous swollen protuberance venter palptrochanter; corniculi weakly formed epistome sclerotised; hypostomal setae h1 h2 ...

Achieving optimal efficiency, good performance, and cost-effectiveness is the main challenge in ship design. Using a bulbous bow part of attaining an excellent design to reduce drag dynamic load caused by waves slamming. The commonly determined shape geometric based on laboratory testing or computer optimization. This article compares probability slamming into catamaran NPL hull without with bo...

Early recruitment process dominated by vegetation reproduction for wetland plant is a key life-history stage affecting species distribution. Extreme climatic events, such as extreme temperature and heavy rainfall have been predicted to become more intense frequent under future climate scenarios. To explore the effect of flooding depth on tubers sprouting early growth Bolboschoenus planiculmis, ...

We describe a gall midge Parampelomyia yukawai Elsayed and Tokuda gen. nov. sp. belonging to the subtribe Schizomyiina (Diptera: Cecidomyiidae: Asphondyliini) based on an integrative taxonomic study. This species forms barely-swollen flower bud galls porcelain berry Ampelopsis brevipedunculata var. heterophylla (Vitaceae) in Japan. The new genus is distinguishable from all known schizomyiine ge...
