Let T be an orientation-preserving Lipschitz expanding map of the circle T. A pre-image selector is a map τ : T → T with finitely many discontinuities, each of which is a jump discontinuity, and such that τ (x) ∈ T(x) for all x ∈ T. The closure of the image of a pre-image selector is called a flower, and a flower with p connected components is called a p-flower. We say that a real-valued Lipsch...

233 Plantains and bananas (Musa sp.) are important starchy staples in Ghana. Processing of plantains into flour is limited as most plantain foods are eaten as boiled, fried or roasted. However, after the introduction on local and foreign markets of instant plantain fufu (popular West African food) flour consisting of plantain flour and cassava starch, interest in plantain flours as a commercial...

Relationships between flowers and pollinators are generally considered cases of mutualism since both agents gain benefits. Fine-tuned adaptations are usually found in the form of strict one-to-one coevolution between species. Many insect pollinators are, however, considered generalists, visiting numerous kinds of flowers, and many flower species (angiosperms) are also considered generalists, vi...

The phenological and ecological study on Punica granatum L., a cultivated and wild species found in outer Himalayan ranges and warm inner valleys (alt. 700 2700m), was carried out during April and May of 2006 and 2007 in Kathmandu Valley. The study covered blooming time, size of flower, its correlation and interaction with the visitors and pollinators. The prime pollinator was Apis cerena along...

In this paper, we handle a remote ikebana (i.e., flower arrangement) system with olfactory and haptic media. In the system, a teacher or a student can hold a flower, adjust the length of the held flower’s stem with a pair of scissors, and impale the flower on a flower pinholder in a 3-D virtual space. We investigate the influence of the size of smell space (defined as a sphere in which we can p...

In this paper, we consider computing the difference between two Horn theories. This problem may arise, for example, if we take care of a theory change in a knowledge base. In general, the difference of Horn theories is not Horn. Therefore, we consider Horn approximations of the difference in terms of Horn cores (i.e., weakest Horn theories included in the difference), which have been proposed a...

We provide a characterization of Horn cores for formulas in conjunctive normal form (CNF) and, based on it, a novel algorithm for computing Horn cores of disjunctions of Horn CNFs that has appealing properties (e.g., it is polynomial for a bounded disjunction). Furthermore, we show that recognizing the Horn envelope of a disjunction of two Horn CNFs is intractable, and that computing a compact ...

Horn description logics (Horn-DLs) have recently started to attract attention due to the fact that their (worst-case) data complexities are in general lower than their overall (i.e. combined) complexities, which makes them attractive for reasoning with large ABoxes. However, the natural question whether Horn-DLs also provide advantages for TBox reasoning has hardly been addressed so far. In thi...

Unicornuate uterus with rudimentary horn is a rare type of uterine malformation associated with obstetrical complications. Rupture of pregnant rudimentary horn is the usual presentation resulting in severe haemoperitoneum with increased maternal morbidity, and at times, mortality. A case of ruptured rudimentary horn pregnancy in a 24-year-old, second gravida, is reported. Exploratory laparotomy...

The relationship between embryo and corpus luteum was studied in an experiment on Barbari goats which were made unilaterally pregnant by embryo transfer 5 days after oestrus. Two embryos were transferred to each recipient whose luteal stage was coinciding with that of the donor. The site of transfer was either ipsilateral uterine horn (group I) or contralateral uterine horn (group II). The "ips...
