To explore the differences in the swimming ability and environmental adaptive abilities between male and female Gambusia affinis, we assessed the differences in burst swimming speeds (Uburst), critical swimming speeds (Ucrit) and their related fin areas, and consumption of energy substances after starvation at 0 (control group), 15, 30, 45, and 60 days, respectively. The results showed that the...

the distribution of yellowfin seabream populations in estuaries and inland rivers in coastal area of the persian gulf and strait of hormuz is presented. based on morphological and mersitic characteristics and also color pattern, these populations are assigned to the recently described sparid fish, acanthopagrus arabicus iwatsuki, 2013 which is distinguished by pelvic and anal fins vivid or stro...

In the article concepts and facts necessary to continue formalization of theory of continuous lattices according to [11] are introduced. and [4] provide the notation and terminology for this paper. 1. PRELIMINARIES The following two propositions are true: (1) For all sets X, A, B such that A ∈ Fin X and B ⊆ A holds B ∈ Fin X. (2) For every set X and for every family F of subsets of X such that ...

Sinocyclocheilus brevifinus sp. nov. is described from a subterranean river at Maohedong Village, Guangxi Zhuang Autonomous Region, Southern China. The new species can be distinguished from all congeners in having functional eyes, last simple dorsal fin ray soft and without serrations along posterior margin, eye diameter small (3.4-5.0 %SL), tip of depressed dorsal fin not reaching vertical at ...

A fully 3D conjugate numerical analysis was performed to reveal the effects of air, R134a refrigerant and water on electromagnetic fields of electronic cooling designs made of arrays of micro pin-fins with integrated ThroughSilicon-Vias (TSVs). The integrated TSV cooling configuration included 8 cylindrical TSVs with 150 μm diameter each and 200 μm height. The external dimensions of the silicon...

This study numerically investigates the effects of the number of bottom openings and the fin spacing on both the natural convection heat transfer and airflow field of the handheld projector with various orientations. The horizontally-oriented 120 mm × 53 mm × 19 mm handheld projector, which had 11 bottom openings and was installed with either 7 plate fins or 13 rows of square pin, was considere...

Rajiform locomotion in fishes is dominated by distinctive undulations of expanded pectoral fins. Unlike other fishes, which typically interact with the fluid environment via multiple fins, undulating rays modulate a single control surface, the pectoral disc, to perform pelagic locomotion, maneuvering and other behaviors. Complex deformations of the broad, flexible pectoral fins occur as the und...

The Finnish Rheumatoid Arthritis Combination Therapy Trial (FIN-RACo) started in 1993, in an era of disappointing results in the treatment of rheumatoid arthritis (RA). The FIN-RACo was the first trial aiming at remission and comparing two different treatment strategies: initially triple therapy with compulsory prednisolone (FIN-RACo strategy), or monotherapy with optional prednisolone (SINGLE ...

Accurate prediction of the performance ofcooling coils is fundamental to the design of efficient ventilation and air-conditioning systems. The actual heat transfer that takes place can be considered as the performance evaluating criteria for any system and this can be expressed in terms of fin efficiency. Fin efficiency is a function of ambient conditions and fin geometry parameters. Obtaining ...
