The studies were conducted on the territory of the Khanty-Mansiysk Autonomous Okrug Yugra (Surgutskiy District) in 20182020 in the Surgut natural wildlife reserve and in 2020 in the vicinity of the Kamennyi Cape ski resort on the left bank of the middle Ob. The paper notes the poor knowledge of the distribution of the Altai mole in the forest zone of Western Siberia, especially on the northern and western borders of the range. Hence, there is almost complete lack of information on its biology and ecology in the area. The Altai mole was collected while counting other small mammals using trapping grooves and guiding fences made of polyethylene membrane; a total of 43 individuals were counted. As in other parts of the forest zone of Western Siberia, the Altai mole near the northern border of the range the left bank of the Middle Ob is confined to mixed and small-leaved forests with rich undergrowth and grassy layer. During the observation period, the maximum abundance of the Altai mole was in 2019. In 2018 and 2020 its abundance was 26 times lower. One of the reasons for such fluctuations can be abiotic factors, in particular, the difference in winter temperature conditions, the height of the snow cover and others. Information about freezing of both Talpa europaea Linnaeus, 1758, and Talpa altaica Nikolsky, 1883, moles during little snowy harsh winters is known.

The purpose of the research is establishing the composition, infection rates, species and group ratio of ectoparasites of the East European vole on the northern border of the range in Western Siberia (Middle Ob Region). Materials and methods. In 2015–2018, in order to capture the provider of ectoparasites, the East European vole, we used methods of trap lines, trap trenches, and fence-traps; we recorded 173 animals from which we collected 881 specimens of gamasid mites, ixodic ticks, lice and fleas. To assess the quantitative indicators of ectoparasites, the indices generally accepted in parasitology were used. Results and discussion. In 2014, it was established for the first time that there is a sibling species of the common vole, the East European vole in the Middle Ob Region (middle taiga of the forest zone of Western Siberia). In the city of Surgut and its neighborhood, this animal is confined to the most transformed biotopes. The ectoparasite complex of the East European vole includes 26 species of parasitic arthropods. By the number of species (13) and individuals, gamasid mites predominate, and the proportion of ixodic ticks, lice and fleas put together is almost 3 times lower. In a climate of the Middle Ob Region, the list of ectoparasites will no doubt grow as the range of habitats expands and the contacts of the East European vole with other small mammals increase, and its role in maintaining pathogen circulation of natural focal infectious diseases will increase.

SummaryChanges in platelets in 48 patients with uterine myoma before and after hysterectomy with and without ovariectomy were examined. Bilateral ovariectomy in 25 cases (ovariec-tomized group) and unilateral or non-ovariectomy in 23 cases (control group) were performed at the hysterectomy. Platelet count and an appearance rate of secondary aggregation decreased at one day after and increased at one week after the operation, similarly in both the ovariectomized and the control group. The appearance rate of secondary aggregation was reflected in an intensity of aggregation at 5 min after the addition of reagent to PRP. At one month after the operation, the appearance rate of secondary aggregation induced by 3 μM ADP showed a statistically significant decrease in comparison with the preoperation value (P <0.05) and the enhancement of 5-min aggregation was still observed in the control group, while ceased in the ovariectomized group. The difference between the two groups was significant (P < 0.05). There was almost no change in the speed and intensity of primary and secondary aggregation during the observation period. No significant differences in collagen-induced aggregation were noted between the two groups. The results suggest that ovarian hormones, mainly estrogen, facilitate platelet activation which is mediated by the so-called secondary aggregation.

Specific Growth Rates

Brook trout (Salvelinus fontinalis) were held in an artificial stream to observe the influence of turbidity on mean daily consumption and specific growth rates. Treatment turbidity levels ranged from clear (<3.0 nephelometric turbidity units (NTU)) to very turbid water (> 40 NTU). Observed mean daily specific consumption rates were standardized to the mean weight of all brook trout tested. Turbidity had no significant effect on mean daily consumption, but specific growth rates decreased significantly as turbidity increased. Brook trout in turbid water became more active and switched foraging strategies from drift feeding to active searching. This switch was energetically costly and resulted in lower specific growth rates in turbid water as compared with clear water. Bioenergetics simulations were run to compare observed growth with that predicted by the model. Observed growth values fell below those predicted by the model and the difference increased as turbidity increased. Abiotic factors, such as turbidity, which bring about changes in the activity rates of fish, can have implications for the accuracy of predicted growth by bioenergetics models.

Background: Platelet hyper-aggregability is an important risk factor for leukoaraiosis. In this study we investigated whether aggravation of leukoaraiosis can be controlled by means of long-term correction of platelet hyper-aggregability.Methods:Twenty-one patients with leukoaraiosis and uncorrected platelet hyper-aggregability were compared with 21 controls matched for age, grade of leukoaraiosis and observation period whose platelet hyper-aggregability was corrected. Platelet aggregability was estimated by an optical analytical method with a nine-stage display using two different concentrations each of adenosine diphosphate (ADP) and collagen (the double ADP method).Results:The mean observation period between two magnetic resonance imaging (MRI) scans for both groups was 4.1 years. In the non-corrected group, moderate to severe aggravation of leukoaraiosis was observed in a large number of patients. In the corrected group, only a small number of patients showed generally mild aggravation of leukoaraiosis. The number of patients showing aggravation of periventricular hyperintensity (PVH) was 7 in 21 in the non-corrected group versus 1 in 21 (p=0.022) in the corrected group, and for aggravation of deep white-matter hyperintensity, these values were 9 in 21 versus 4 in 21, respectively. Thus, the difference was more significant if the degree of aggravation was taken into account.Conclusion:The progress of leukoaraiosis is greatly inhibited by long-term correction of platelet hyper-aggregability.

Geographic information system-based multi-criteria decision analysis (GIS-MCDA) is a process of decision making where geographical data and value judgments are integrated. Analytic hierarchy process (AHP) is a useful technique in MCDA for determining weights. This study focuses on the evaluation of GIS-MCDA using different uncertainty levels in AHP. Best suitable sites for tiger habitats are located and analyzed in Sariska Wildlife Reserve, India using crisp and fuzzy AHP in GIS-MCDA, and thereafter, an optimal habitat suitability model is proposed. The percentage deviation over the uncertainty levels ranges slightly over 5%. The relative difference between CAHP and FAHP is nearly 2.7%. Chi-square test reveals relationship between the degree of uncertainty and the difference between the maps. For real-world situations with increased variability, fuzzification is preferred and shows the best results. The worldwide declining status of the tigers is a serious threat to the overall biodiversity, and the methods adopted in this study thus target their conservation and management.

A new trial for evaluating the effectiveness of adjuvant chemotherapy in high-grade soft-tissue sarcomas of the extremities in adult patients is presented. All patients after local treatment were randomized into two arms, one without further therapy and the other to receive adjuvant chemotherapy (Adriamycin [Farmitalia-Carlo Erba, Milan, Italy], 450 mg/m2). The preliminary results of the study are reported at a median observation period of 27.6 months. Of the 59 patients who entered the study, 79.1% in the chemotherapy group are without sign of disease, whereas the corresponding figure in the nonadjuvant chemotherapy group is 54.3%. The difference between the two groups is statistically significant (P less than .005, log rank test). These preliminary observations encourage continuation of the study.

The Difference

Before the Panic of 1907 the large New York City banks were able to maintain the call loan market's liquidity during panics, but the rise in outside lending by trust companies and interior banks in the decade leading up the panic weakened the influence of the large banks. Creating a reliable source of liquidity and reserves external to the financial market like a central bank became obvious after the panic. In the call loan market, like the REPO market in 2008, lack of information on the identity of lenders and volume of the market hindered attempts to stop panic-related depositor withdrawals. Our new estimates of who was participating in the call loan market reveal that it did not contract after 1907; while the trust companies became less important, the New York national banks and outside lenders more than made up the difference.

Line Movement

The present paper aims to analyse the social representation of feminism within the “Women Against Feminism” (WAF) on-line movement that is based on a shared blog which gained significant coverage in the U.S. and U.K. media since the summer of 2014. Using the method of quantitative content analysis and the insights provided by social representations theory, the paper will disclose what lies behind the concept of ‘feminism’ for the group embracing the WAF movement and also aims to find whether the members of this on-line community can be described as postfeminists. The article will conclude that the social representation of feminism within the WAF on-line movement is not based on a lack of information, but rather on a stereotypical understanding of the concept and on a non-nuanced perspective upon the history of feminism and its current developments (in particular the difference between post-feminism and third wave feminism). Moreover, similar arguments raised against feminism have been also drawn in the past, WAF sharing similar arguments with the ‘80s media backlash against feminsim.
