Rudimentary horn is an anatomic variant of unicornuate uterus which a mullerian duct anomaly resulting from the incomplete fusion ducts. The prevalence congenital uterine malformations about 3.2%Pregnancy in rudimentary extremely rare condition occurring 1 76,000 to 1,40,000 pregnancies. Unicornuate with maybe associated gynecological and obstetric complications like infertility, endometriosis,...

Horn players have observed that timpani strokes can interfere disruptively with their playing, especially when they are seated close to the timpani. Measuring the horn's transfer function in the bell-to-mouthpiece direction reveals that the horn behaves as an acoustic impedance matching device, capable of transmitting waves with pressure gains of at least 20 dB near horn playing resonances. Dur...

Resistance to insecticides remains a major problem for the successful control of the horn Xy, Haematobia irritans irritans (L.), one of the most important pests of cattle in many countries including the United States. The organophosphate (OP) insecticide diazinon has been used to control pyrethroid-resistant populations of the horn Xy. There are only a few reported cases of horn Xy resistance t...

Scarab beetles exhibit an astonishing variety of rigid exo-skeletal outgrowths, known as "horns". These traits are often sexually dimorphic and vary dramatically across species in size, shape, location, and allometry with body size. In many species, the horn exhibits disproportionate growth resulting in an exaggerated allometric relationship with body size, as compared to other traits, such as ...

The horn fly, Haematobia irritans, is one of the most economically important pests of cattle. Insecticides have been a major element of horn fly management programs. Growing concerns with insecticide resistance, insecticide residues on farm products, and non-availability of new generation insecticides, are serious issues for the livestock industry. Alternative horn fly control methods offer the...

We report complexity results about redundancy of formulae in 2CNF form. We first consider the problem of checking redundancy and show some algorithms that are slightly better than the trivial one. We then analyze problems related to finding irredundant equivalent subsets (i.e.s.) of a given set. The concept of cyclicity proved to be relevant to the complexity of these problems. Some results abo...

This study was performed to evaluate the efficacy of injection of essential oil of Eugenia caryophyllata in the kid horn buds, as a new chemical technique for disbudding. Five-day-old healthy goat kids from both sexes (n = 16) were divided randomly into 4 equal groups. In groups 1, 2 and 3, 0.2 mL of clove essence and in group 4 (control) 0.2 mL of normal saline was injected into the left horn ...

A 73-year-old Japanese woman presented with cutaneous horn on the right cheek. The resected tumor was 9 mm in diameter, with 14 mm protrusion, and showed exophytic growth with marked papillomatosis. Histopathology showed proliferation of atypical melanocytes with melanin pigments in the epidermis and dermis under the cutaneous horn. These cells were confined to the base of the cutaneous horn, a...

Identifying and exploiting hidden problem structures is recognized as a fundamental way to deal with the intractability of combinatorial problems. Recently, a particular structure called (strong) backdoor has been identified in the context of the satisfiability problem. Connections has been established between backdoors and problem hardness leading to a better approximation of the worst case ti...
