The wish to have a child is a deep instinctual urge; the ability to care for the child is not innate and must be nurtured. In fact, many new mothers feel torn between their desire for a child and their wish to be free of long involvements and responsibilities. Becoming a mother is a testing time for a woman. Then she takes on the truly feminine role as opposed to just being a sex partner in a r...

BACKGROUND To evaluate medical and dental students' utilization of electronic information resources. METHODS A web survey sent to 837 students (49.9% responded). RESULTS Twenty-four per cent of medical students and nineteen per cent of dental students searched MEDLINE 2+ times/month for study purposes, and thiry-two per cent and twenty-four per cent respectively for research. Full-text arti...

Whether it be at a party or at a tavern or while being examined by a physician, on announcing that you are a mathematician, you are likely to be greeted with comments about your companion’s failure in high school math, or a request for a brief account of the proof of Fermat’s Last Theorem, or perhaps an offer of a counterexample to the Four Color Theorem. Your parents, your friends and relative...

We present a “reasonable” statement about Lie algebras that is equivalent to the Four Color Theorem.

Twenty four new strains were tested for their yield, quality and Leaf Curl Virus (ClCuV) resistance. NIAB-111/S, NIAB-98 and NIAB-999 were significantly high fruit bearing varieties at 90 days completing 59.54, 48.26 and 46.00% fruiting respectively. Seed cotton yield of VH-142 was highest with 5417 kgha-1 and 52 per plant boll bearing, DNH-57 and NIAB-999 remained second and third with 5234 an...

Software model-checking based on the CEGAR framework can be made more precise by separating non-determinism from the lack of information due to abstraction. The two can be modeled individually using four-valued Belnap logic. In addition, this logic allows reasoning about negations effectively and thus enables checking of full CTL. In this paper, we present YASM – a new symbolic software model-c...

Let D be a disc, and let X be a finite subset of vertices on the boundary of D. An essential part of the proof of the four colour theorem is the fact that many sets of 4-colourings of X do not arise from the proper 4-colourings of any graph drawn in D. In contrast to this, we show that every set of 3-colourings of X arises from the proper 3-colourings of some graph drawn in D.

Extensions of Sherman’s theorem to convex functions of higher order and to real weights are obtained by using Taylor’s formula. New upper bounds for Sherman’s difference and generalized inequalities are established. Some related Cauchy-type means are discussed.

PURPOSE We had reported the surgical outcome of reverse skin redraping technique for restoration of previously performed epicanthoplasty. In this study, we introduce a modified reverse skin redraping technique that added mini-epicanthoplasty in patients with unsatisfactory results after epicanthoplasty. METHODS Three hundred twenty-four patients (288 female and 36 male patients) who had unsat...

This training study investigates how children learn to refer to things unambiguously. Two hundred twenty-four children aged 2.6, 3.6, and 4.6 years were pre- and posttested for their ability to request stickers from a dense array. Between test sessions, children were assigned to a training condition in which they (a) asked for stickers from an adult, (b) responded to an adult's requests for sti...
