Abstract
This study assessed the intrapersonal and interpersonal functioning of a three-couple expedition group that included a 2 1/2-year-old child which was ice-locked on a boat in the High Arctic during a major portion of the expedition. Personality assessment indicated that team members were generally well adjusted, scoring relatively higher on well-being and achievement and relatively lower on stress reactivity. Weekly mood ratings showed that the group exhibited significantly higher positive than negative affect. Reported negative events were relatively most frequent at the beginning of the Arctic stay and toward the end of the darkness period and were lowest during the initial darkness interval. The period of darkness had both a salutary and negative impact. A highly important means of coping with stress was seeking emotional support from one's partner. Selection of couples with strong bonds with their partner appears to be one viable approach for crew selection for long-duration missions.

Abstract
AIM: To specify a 24-h profile of arterial pressure (AP) in hypertensive patients working in duty regime in the Far North (Tyumen Region). MATERIAL AND METHODS: AP parameters were studied in 155 males aged 25-59 with hypertension of stage I, II who were employed for duty work in the Far North areas and 38 control patients with hypertension stage I, II living in a moderate climatic zone (Tyumen). The groups were comparable by gender, age, duration of hypertension, office systolic and diastolic AP (SAP and DAP). All the patients have undergone 24-h monitoring of AP with assessment of basic mean parameters. RESULTS: The study group patients had scare symptoms and lower mean 24-h SAP, but high AP variability, high DAD as reflection of more significant structural changes of vessels and special functioning of the autonomic nervous system in the North. Mean 24-h AP showed more unfavourable changes in hypertensive subjects who had flight from Yamburg-Moscow-Yamburg. CONCLUSION: The data of the study dictate the necessity to develop a differentiated risk strategy for health promotion, prevention and treatment of hypertension in those who work in the North of Tyumen Region in duty regime.

Abstract
To understand better the link between atmospheric CO2 concentrations and climate over geological time, records of past CO2 are reconstructed from geochemical proxies. Although these records have provided us with a broad picture of CO2 variation throughout the Phanerozoic eon (the past 544 Myr), inconsistencies and gaps remain that still need to be resolved. Here I present a continuous 300-Myr record of stomatal abundance from fossil leaves of four genera of plants that are closely related to the present-day Ginkgo tree. Using the known relationship between leaf stomatal abundance and growing season CO2 concentrations, I reconstruct past atmospheric CO2 concentrations. For the past 300 Myr, only two intervals of low CO2 (2,000 p.p.m.v.) concentrations. These results are consistent with some reconstructions of past CO2 (refs 1, 2) and palaeotemperature records, but suggest that CO2 reconstructions based on carbon isotope proxies may be compromised by episodic outbursts of isotopically light methane. These results support the role of water vapour, methane and CO2 in greenhouse climate warming over the past 300 Myr.

Abstract
For determinination of the significance of asymptomatic bacteriuria (AB) among the conscripts in the North was performed a comparative study of 101 volunteers who had no complaints and urinary tract infection (UTI) and a history of 206 patients treated at the stationary UTI. Diagnostically important AB in soldiers was 3% and corresponded to inflammation of the urethra and prostate. Negative impact of subextreme conditions of service in the development of AB from the soldiers in the 12 months has not been established. AB in young men in 27% of such cases was accompanied by leukocyturia, in 36% with bacteriuria, determined by the overall analysis of urine, which is a comprehensive method of identifying the primary UTI.

Abstract
Results of hospital check-up and treatment of female soldiers, female members of servicemen's family and retirees of Ministry of Defence of Russian Federation were analyzed for the purpose of improvement of prophylaxis, treatment of urinary tract infections and estimation of factors of military service in the progress of UTI in female soldiers in conditions of North. It was determined that in the structure of UTI in female soldiers aged before 40 prevail acute cystitis and acute pyelonephritis combined with phologistic gynaecological abnormality, aged after 40 - chronic pyelonephritis combined with concomitant urolithiasis and chronic cystitis. Factors of military service influence on the progress of acute UTI and early approach of chronic UTI in female soldiers.

Abstract
A comparative study of air quality in terms of microbiological indicators in the barracks room personnel a number of units of the Northern Fleet is perfomed. The direct dependence of the degree of microbial contamination of air and the frequency of respimratory diseases from the specific volume of space per person is showed. Criteria for assessing air quality in terms of microbiological indicators and a set of measures to improve it are suggested.
