OBJECTIVES The aim of the present project was to assess population exposure to pesticides in the vicinity of pesticide dump sites and make a preliminary evaluation of the potential health hazards to humans. MATERIALS AND METHODS Of the 286 pesticide dump sites registered in Poland, 40 were selected as the largest source of ecological hazard. The application of the Hazard Ranking System made i...

The conserved Asn 229 of thymidylate synthase (TS) forms a cyclic hydrogen bond network with the 3-NH and 4-O of the nucleotide substrate 2'-deoxyuridine 5'-monophosphate (dUMP). Asn 229 is not essential for substrate binding or catalysis [Liu, l., & Santi, D. B. (1993) Proc. Natl. Acad. Sci. U.S.A. 90, 8604-8608] but is a major determinant in substrate specificity [Liu, l., & Santi, D. V. (199...

The Microsoft Windows kernel provides a heap-like memory management, called "pools". Whenever some kernel-mode code requires an amount of memory, it is allocated from a pool. Ignoring the documented interface and searching the whole dump of physical memory for signatures of pool allocations allows the forensic examiner to gain information not only from currently active but also from freed and n...

You have just finished a bowl of chicken soup for lunch. As you clean up, you wash out the bowl and throw away the can. A garbage truck will haul the can to the dump where it will lie among other trash. A female fly might lay her eggs in the can, and her offspring might fly from the dump, feed on some decayed food, and then rest on top of someone’s peanut butter sandwich. Each of these interact...

This paper presents an analysis of the effects of market structure on the propensity of firms to dump goods. The analysis of Brander and Krugman is extended to show that in the presence of transportation costs, bilateral intra-industry trade is not possible without dumping. Contrary to the conventional wisdom, this paper finds that firms in markets with a large number of domestic competitors ar...

The theory of optimal control together with that of transient probe absorption spectroscopy are applied for control and detection of molecular wave packet dynamics in the weak response regime. We obtain a globally optimal pump–dump control field which drives the initial state to the predefined target, focused at the inner-turning point region of the electronic ground state potential. As for the...

The studies were carried out on typical chernozem. purpose of the research was to develop resource-saving technological methods crop cultivation, ensuring an increase in yield and economic efficiency production. work a long-term stationary field experiment against background two types rotations: 2007-2010 – grain-fallow-hoe (black fallow winter wheat sugar beet barley) 2013-2020 grain-fallow so...

The INEX QA track (QA@INEX) aims to evaluate a complex question-answering task. In such a task, the set of questions is composed of complex questions that can be answered by several sentences or by an aggregation of texts from di erent documents. Question-answering, XML/passage retrieval and automatic summarization are combined in order to get closer to real information needs. Based on the grou...

In this paper, we investigate methods for automated localization of leaks and dumps in an open channel flow. We propose a framework under which we solve this important system health monitoring problem by using a network of level sensors and estimation algorithms. We first discuss numerical techniques for simulating a channel with leaks or dumps. We then give results of a multiple-model estimati...
