The chronobiology of alertness Some preliminary work for an application in the area of road safety

Introduction. In the course of their professional activities, traffic police inspectors of State Road Safety Inspectorate (SRSI) are exposed to harmful working conditions. The aim of study is to provide scientific justification for the periods of service of inspectors that are important for the diagnosis of early signs of professionally caused diseases. Materials and methods. The study was carried out in a group of traffic police inspectors of the traffic police in accordance with the ethical standards set forth in the Declaration of Helsinki, 1975 (with additions, 1983), a positive conclusion of the ethical committee. The age of the traffic police officers was 24-50 years old, the experience was 1-19 years (average values 34±0.46 and 8.21±0.40 years). Results. In the course of the study, a class of working conditions was determined-3.4. low-level traffic police officers showed signs of disadaptation, a high risk of morbidity with temporary disability and professionally caused pathology of the cardiovascular, musculoskeletal, nervous, endocrine, and digestive systems. Conclusions. It is advisable to conduct an in-depth preventive medical examination of inspectors after 1-2 years of service. The first 4 years of service are important for preventive measures.

Mississippian Rocks

In central Utah, the major pre-Mississippian unconformity is fairly well understood at most of the localities where it is recognized. However, the unconformity is more enigmatic in Rock Canyon of the central Wasatch Range. At this locality, dolomitization of most pre-Mississippian rocks obscures stratigraphic identification of Devonian and older units. The absence of any identifiable angular relationship further complicates resolution. Because of this, both identification of the stratigraphic level of the unconformity and, consequently, its magnitude remain controversial. Large-size dolomite samples taken in Rock Canyon at closely spaced intervals for the 3.6-m directly below definite Upper Devonian rocks yield microfossils, including conodonts, in the uppermost 1.6-m of that interval that indicate no unconformity exists between the Cambrian Maxfield Limestone and the Upper Devonian-Lower Mississippian Fitchville Dolomite at the horizon previously identified as unconformable. Rather, an unknown thickness of dolomitized Upper Devonian Pinyon Peak Formation and probable older rock (possibly Bluebell Dolomite and Victoria Formation) occurs between the top of definite Maxfield and base of the Fitchville. The identification of the unconformity horizon remains unknown. Our preliminary work outlines a promising procedure for future understanding of the magnitude and stratigraphic level of the unconformity.
