We present 3D hydrodynamic simulations of ram pressure stripping in dwarf galaxies. Analogous studies on this subject usually deal with much higher ram pressures, typical of galaxy clusters, or mild ram pressure due to the gas halo of the massive galactic companions. We extend over previous investigations by considering flattened, rotating dwarf galaxies subject to ram pressures typical of poor...

PURPOSE Retinal arterial macroaneurysm (RAM) has been reported in association with branch retinal vein occlusion (BRVO), and usually BRVO precedes RAM. We present a long-term follow-up case report of unilateral multiple RAMs that developed BRVO following ruptured RAM in the same retinal quadrant. CASE PRESENTATION An 80-year-old woman presented with floaters in her right eye in June 2012. Vis...

The basic objectives and procedures for successful crossbreeding of beef cattle were considered, with special reference to the levels of realized hybrid vigor that might be anticipated for different crossbreeding programs involving the American Brahman (Z1) and European (Ej) breeds. Intralocus heterozygosis levels with respect to breed origin of genes (breed heterozygosis) were computed for var...

GSP's need their humans, and love them dearly. They are often referred to as "Velcro Dogs" because they can be very clingy. They are anxious to please and fond of children, though standoffish with strangers. They are also very intellegent dogs and many are "practical jokers". If they do not receive enough exercise, they can become destructive or nervous if neglected. If you are thinking about a...

platelet activating factor (paf) is a novel signaling phospholipids that in addition to platelet activation has many biological properties. the acrosome reaction, as an essential step in mammalian fertilization, can occur in response to several agents such as paf. therefore, the present study aimed to assess the effect of paf on the motility and acrosome reaction of ram spermatozoa. semen was c...

the hypothesis of this experiment was that the various sources of dietary fat with different dietary ratios of polyunsaturated fatty acids (pufas) to saturated fatty acids (sfas) would alter the reproduction parameters of mature rams. twelve mature rams were randomly allotted to one of four dietary treatments in a completely randomized design. dietary treatments were: 1) ration with 4% soybean ...

One of the great challenges in the processing of materials using Equal Channel Angular Pressing (ECAP) is the high forming forces required to produce large shear deformation in the material. Researchers show that the friction forces between the die and the sample constitute a great part of the total forming forces. Recently, ultrasonic vibrations are successfully implemented into the ECAP proce...

In Saccharomyces cerevisiae, polarized morphogenesis is critical for bud site selection, bud development, and cell separation. The latter is mediated by Ace2p transcription factor, which controls the daughter cell-specific expression of cell separation genes. Recently, a set of proteins that include Cbk1p kinase, its binding partner Mob2p, Tao3p (Pag1p), and Hym1p were shown to regulate both Ac...
