Abstract. Increasing demands on ecosystems, decreasing biodiversity, and climate change are among the most pressing environmental issues of our time. As changing weather conditions leading to increased vector-borne diseases heat- flood-related deaths, it is entering collective consciousness: human health issues. In public health, field addressing these known as health. This addresses both effec...

“When you are high, it is tremendous. Shyness goes, the right words and gestures are suddenly there, the power to seduce and captivate others a felt certainty. Feelings of ease, intensity, power, well-being, financial omnipotence and euphoria now pervade one’s marrow. But somehow, this changes. The fast ideas are far too fast and there are far too many, overwhelming confusion replaced by fear a...

Maxillectomy often leads to oralnasal or excessive oral-pharyngeal communication. The remaining teeth may need further preparation for various reasons, including crown or fixed dental prosthesis restoration. High-volume water is used in conjunction with highspeed tooth preparation to avoid the excessive heat generation that could endanger the health of the pulp. The water aerosol generated by t...

The photooxidation of thebaine (3) with a sun lamp affords two main products: hydrodibenzofuran 10 (major) and benzofuran 11 (minor). The latter compound becomes predominant if a Hg lamp is used instead of a sun lamp. The formation of 10 proceeds via an endoperoxide intermediate that undergoes oxidation at the nitrogen atom. Protection of the nitrogen either by protonation or quaternization pre...

renewable energy sources (res), especially wind power plants, have high priority of promotion in the energy policies worldwide. an increasing share of res and distributed generation (dg), should, as has been assumed, provide improvement in reliability of electricity delivery to the customers. paper presented here concentrates on electricity storage systems technologies and applications pinpoint...

This paper is a study of decompositional proof techniques applied to the ver-iication of a model of a real world hybrid system, an aircraft landing gear. We present a formal description of these techniques (taken from Halwbachs et.al. 5]) and look at two ways of applying them. We discover, and correct , a aw in the theory, but conclude ultimately that when dealing with a plant-controller combin...

Medical statistics (biostatistics), as a vital essential part of modem life, does raise some fundamental ethical issues. Surprisingly, this aspect seems to have been totally ignored by books on medical ethics. This paper discusses how the statistical aspects affect the ethics. The relation between biostatistics and medical research is explored. All stages of a medical research exercise are ...

“Scrap Your Boilerplate” (SYB) is an established style of generic functional programming. The present paper reconstructs SYB within the Prolog language with the help of the univ operator and higher-order logic programming techniques. We pay attention to the particularities of Prolog. For instance, we deal with traversal of non-ground terms. We also develop an alternative model of SYB-like trave...
