Abstract

Radiographic non-destructive examination of the round timber became a popular technique in the middle of the twentieth century when radiography was first applied to study the structure of materials. The X-ray television testing equipment is widely used in non-destructive inspection for a long time, but up to now, this equipment was not applied to find the heartwood rot in wood sticks of any diameter. This article analyzes the innovative method of non-destructive testing of low-quality wood, which was performed using the portable X-ray television testing system. Furthermore, it provides positive results of experimental investigations. In addition, this article describes possibility of taking quality images of the internal structure of wood, as well as possibility of the automated image processing. © IAEME Publication.

14. New and interesting lichen records from the Ural Mountains, Russia

Author

Paukov, A. G., Gagarina, L. V., Frolov, I. V., Paukov, A. G., Gagarina, L. V., and Frolov, I. V.

Abstract

Ten species of lichenized ascomycetes are reported from the Urals. Aspicilia spermatomanes, Fuscidea praeruptorum, Lepra excludens, L. monogona, Metamelanea caesiella and Pertusaria amarescens are new to Russia while Bryobilimbia ahlesii, Lecanora orosthea, L. rouxii and Tephromela grumosa are new for the Urals. Our records considerably extend the ranges or fill gaps in the formerly disjunctive distributions of these species. The morphology, secondary chemistry and ecology of the species are discussed. © 2017, Estonian Naturalists' Society. All rights reserved.

16. Resonance contribution of scalar color octet to $t \bar{t}$ production at the LHC in the minimal four color quark-lepton symmetry model

Author

Frolov, I. V., Martynov, M. V., Smirnov, A. D., Frolov, I. V., Martynov, M. V., and Smirnov, A. D.

Abstract

The scalar color octet contribution to the resonance $t\bar{t}$-pair production at the LHC is calculated and analysed with account of the one loop effective two gluon vertex. It is shown that this contribution from the scalar color octet $F_2$ predicted by the minimal model with the four color quark-lepton symmetry is for $\sqrt{s}=13$ TeV of about a few percents for $750 < m_{F_2} < 1800$ GeV and can exceed 10% for $400 < m_{F_2} < 750$ GeV. It is also pointed out that the search for the scalar octet $F_2$ as the resonance in the dijet mass spectra seems to be difficult because of the smallness of its one loop effective two gluon interaction., Comment: 12 pages, 5 figures, accepted for publication in Modern Physics Letters A

17. Mass limits for the chiral color symmetry $G'$-boson from LHC dijet data

Author

Frolov, I. V., Smirnov, A. D., Frolov, I. V., and Smirnov, A. D.

Abstract

The contributions of $G'$-boson predicted by the chiral color symmetry of quarks to the differential dijet cross-sections in $pp$-collisions at the LHC are calculated and analysed in dependence on two free parameters of the model, the $G'$ mass $m_{G'}$ and mixing angle $\theta_G$. The exclusion and consistency $m_{G'}-\theta_G$ regions imposed by the ATLAS and CMS data on dijet cross-sections are found. Using the CT10 (MSTW~2008) PDF set we show that the $G'$-boson for $\theta_G=45^{\circ}$, i.e. the axigluon, with the masses $m_{G'} < 2.3 \,\, (2.6) \,\, \mbox{TeV}$ and $m_{G'} < 3.35 \,\, (3.25) \,\, \mbox{TeV}$ is excluded at the probability level of $95\%$ by the ATLAS and CMS dijet data respectively. For the other values of $\theta_G$ the exclusion limits are more stringent. The $m_{G'}-\theta_G$ regions consistent with these data at $CL=68\%$ and $CL=90\%$ are also found., Comment: 13 pages, 3 figures, accepted for publication in Modern Physics Letters A

Abstract

For the first time in serveral years, the El Nino-Southern Oscillation did not dominate regional climate conditions around the globe. A weak La Ni a dissipated to ENSOneutral conditions by spring, and while El Nino appeared to be emerging during summer, this phase never fully developed as sea surface temperatures in the eastern conditions. Nevertheless, other large-scale climate patterns and extreme weather events impacted various regions during the year. A negative phase of the Arctic Oscillation from mid-January to early February contributed to frigid conditions in parts of northern Africa, eastern Europe, and western Asia. A lack of rain during the 2012 wet season led to the worst drought in at least the past three decades for northeastern Brazil. Central North America also experienced one of its most severe droughts on record. The Caribbean observed a very wet dry season and it was the Sahel's wettest rainy season in 50 years. Overall, the 2012 average temperature across global land and ocean surfaces ranked among the 10 warmest years on record. The global land surface temperature alone was also among the 10 warmest on record. In the upper atmosphere, the average stratospheric temperature was record or near-record cold, depending on the dataset. After a 30-year warming trend from 1970 to 1999 for global sea surface temperatures, the period 2000-12 had little further trend. This may be linked to the prevalence of La Ni a-like conditions during the 21st century. Heat content in the upper 700 m of the ocean remained near record high levels in 2012. Net increases from 2011 to 2012 were observed at 700-m to 2000-m depth and even in the abyssal ocean below. Following sharp decreases in to the effects of La Ni a, sea levels rebounded to reach records highs in 2012. The increased hydrological cycle seen in recent years continued, with more evaporation in drier locations and more precipitation in rainy areas. In a pattern that has held since 2004, salty areas of the ocea

Abstract

Central Europe in general is poor in Teloschistaceae lichen crusts (Caloplaca s. lat.). Diversity of these lichens is increased by the occurrence of some Arctic, Mediterranean and continental species, which are here close to the limits of their range. Examples include: 1) Caloplaca interfulgens, previously known from arid territories of northern Africa and western Asia, is recorded, surprisingly, from Austria, Czech Republic, Germany, Slovakia and southern Russia. In Central Europe, it is restricted to scattered xerothermic limestone outcrops. 2) Caloplaca scabrosa, previously known only from Svalbard, is recorded from the Sudetes in the Czech Republic. It is similar to, but not conspecific with, C. furfuracea. Its diagnostic characters include a blastidiate thallus and the presence of atranorin. Our results show that atranorin is absent in the majority of taxa related to C. furfuracea with only two exceptions: the sample from Eastern Carpathians, here called C. aff. scabrosa, and in one Sudetan sample identified as C. crenularia. 3) Caloplaca emilii, newly described below, is closely related to the Mediterranean C. areolata. We consider C. emilii a Mediterranean species rarely occurring in higher latitudes in Austria, the Czech Republic and Germany. It is distinguished from C. areolata mainly by the presence of vegetative diaspores (blastidia); a possible role of blastidia in the distribution pattern of C. emilii is discussed below. Status of the names Caloplaca areolata, C. isidiigera and C. spalatensisis, formerly used for the new taxon, is clarified. 4) Caloplaca molariformis, newly described below, belongs to the Pyrenodesmia group (a lineage of Caloplaca without anthraquinones). It is a continental species, frequently collected on limestone or lime-rich tuffs in steppes or deserts in Turkey, Iran, western Kazakhstan and southern Russia, and is also known from eastern Ukraine and southern Slovakia. Caloplaca molariformis is characterized by its thick thallus wi

Abstract

The contributions of $G'$-boson predicted by the chiral color symmetry of quarks to the charge asymmetry $A_C(p p \to t\bar{t})$ in $t \bar{t}$ production at the LHC and to the forward-backward asymmetry $A_{\rm FB}(p\bar{p} \to t\bar{t})$ in $t\bar{t}$ production at the Tevatron are calculated and analysed in dependence on two free parameters of the model, the $G'$ mass $m_{G'}$ and mixing angle $\theta_G$. The $m_{G'} - \theta_G$ regions of $1 \sigma$ consistency with the CMS data on the cross section $\sigma(pp \to t\bar{t})$ and on the charge asymmetry $A_C(p p \to t\bar{t})$ are found and compared with those resulted from the CDF data on the cross section $\sigma(p\bar{p} \to t\bar{t})$ and on the forward-backward asymmetry $A_{\rm FB}(p\bar{p} \to t\bar{t})$ of $t \bar{t}$ production at the Tevatron with account of the current SM predictions for $A_{\rm FB}(p\bar{p} \to t\bar{t})$., Comment: 11 pages, 3 figures, accepted for publication in Modern Physics Letters A; v2: corrected misprint, added references

Abstract

Oceanographic studies during IPY 2007/2009 provided new information on spatial variability of hydrographic parameters. Detailed pattern of irregularities in the Atlantic Water (AW) layer was documented in the Nansen Basin. Spatial scales of temperature distribution and the depth of the upper boundary of AW were estimated. In the Canadian Basin spatial variations of temperature were less pronounced. During IPY 2007/2008 the area occupied by AW has increased. According to our estimations the positive temperature anomaly in some regions was as high as 1,5°C, which is about 70% of temperature maximum in 1950-1959. The upper boundary of AW (zero degree isotherm) rose by 40-120 m around the Mendeleyev Ridge and in the Amundsen Basin. At the same time, in the Canada Basin and in the western Fram Strait the AW thickness decreased by similar value. Heat content of the AW layer around the major part of the Arctic Ocean exceeded mean climatic value, except for the compact area north of Franz Josef Land, where small negative anomaly was observed. Throughout 2008 mean temperature and maximum temperature in the AW layer were higher than mean climatic values. At the same time, the state of AW layer in the inflow region, east of Fram Strait along the continental margin to the Laptev Sea, substantially changed in comparison with 2007. Mean and maximum temperature of AW dropped by 0,25/0,5°C. Heat content and the Thickness of AW layer have also decreased. Basing on the obtained results, we conclude that during 2008/2009 there was a neneral reverse trend in AW parameters towards mean climatic results.

Abstract

The long-term variability of the intermediate Atlantic Water (AW) layer in the Arctic Ocean is analyzed. We reveal a positive temperature and negative salinity linear trends for the entire Arctic Ocean. Warming and cooling tendencies in the Canada Basin lags those for the Eurasian Basin by 9-10 years with similar duration for the warming and cooling periods for both basins. In contrast, salinity tendency in the Canada Basin lags those in the Eurasian Basins by 8-16 years salinity, and durationof saltier and fresher anomalies is different. The interannual variability for the depth of AW upper boundary and AW core temperature is studiedusing two first modes of the Empirical Orthogonal Function (EOF) decomposition exhibit unique patterns that have been never observed over the entire period of instrumental observations. For 2009, our analysis reveals the AW recovery to already observed patterns. our examination also shows that the AW warming and cooling is also accompanied by changes in depthsof the AW upper boundary and the AW core that provides evidence for the different volume and properties of the AW during warmer and cooler phases. In this respect, the AW warming in 1950s, 1990s differs from those in during the International Polar Year 2007/2008

Abstract

The large scale features of the vertical thermohaline structures in the Arctic Ocean during 2007-2009 were considered to reveal the changes in temperature and salinity in comparison with the historical data. In general, the main features of vertical thermohaline structures have remained unchanged over the Arctic and demonstrate the frontal barrier area between Eurasian and American basins. However, the unique summer atmospheric forcing in 2007 resulted in the considerable thermohaline changes in the surface layer. The large areas of positive and negative anomalies in temperature and salinity have been formed over the Arctic Ocean. The volumetric changes in the water masses with different temperature and salinity gradation have been also observed. The volume of Atlantic Waters with temperatures above 0°C and salinity above 34,6 increased at 22% in 2007 in comparison with 1970-1979 mean. The changes in the deeper layers habe also been revealed. Thus, the volume of intermediate waters with temperatures ranged from -0,4 to 0°C and salinities above 34,6 decreased at 30% in 2007. The most saline and cold bottom waters became warmer and fresher.

Abstract

This paper examines the temperature and salinity patterns and evolution in the surface layer of the Arctic Ocean in 2007-2009 and deals with the factors impacting the extreme changes both in temperature and salinity in 2007. The large areas of positive and negative anomalies in temperature and salinity have been formed over the Arctic Ocean with the apparant frontal barrier areea between Eurasian and American basins. The followed years (2008-2009) exhibit the reducing of thermohaline anomalies between the two basins assuming gradually rcovering to the initial state. Considering the mean salinities within 5-50 m depth one can claim that the positive linear trend is evident both in Eurasian and American basinss since 1950 to 1993 while the intensive freshening was obsserved in American basin in 2007-2009. We intend that these changes in salinity can be assumed as the signature of non-stationary nature of all Arctic marine environments.

Abstract

Oceanographic studies during IPY 2007/2009 provided new information on spatial variability of hydrographic parameters. Detailed pattern of irregularities in the Atlantic Water (AW) layer was documented in the Nansen Basin. Spatial scales of temperature distribution and the depth of the upper boundary of AW were estimated. In the Canadian Basin spatial variations of temperature were less pronounced. During IPY 2007/2008 the area occupied by AW has increased. According to our estimations the positive temperature anomaly in some regions was as high as 1,5°C, which is about 70% of temperature maximum in 1950-1959. The upper boundary of AW (zero degree isotherm) rose by 40-120 m around the Mendeleyev Ridge and in the Amundsen Basin. At the same time, in the Canada Basin and in the western Fram Strait the AW thickness decreased by similar value. Heat content of the AW layer around the major part of the Arctic Ocean exceeded mean climatic value, except for the compact area north of Franz Josef Land, where small negative anomaly was observed. Throughout 2008 mean temperature and maximum temperature in the AW layer were higher than mean climatic values. At the same time, the state of AW layer in the inflow region, east of Fram Strait along the continental margin to the Laptev Sea, substantially changed in comparison with 2007. Mean and maximum temperature of AW dropped by 0,25/0,5°C. Heat content and the Thickness of AW layer have also decreased. Basing on the obtained results, we conclude that during 2008/2009 there was a neneral reverse trend in AW parameters towards mean climatic results.

Abstract

The long-term variability of the intermediate Atlantic Water (AW) layer in the Arctic Ocean is analyzed. We reveal a positive temperature and negative salinity linear trends for the entire Arctic Ocean. Warming and cooling tendencies in the Canada Basin lags those for the Eurasian Basin by 9-10 years with similar duration for the warming and cooling periods for both basins. In contrast, salinity tendency in the Canada Basin lags those in the Eurasian Basins by 8-16 years salinity, and durationof saltier and fresher anomalies is different. The interannual variability for the depth of AW upper boundary and AW core temperature is studiedusing two first modes of the Empirical Orthogonal Function (EOF) decomposition exhibit unique patterns that have been never observed over the entire period of instrumental observations. For 2009, our analysis reveals the AW recovery to already observed patterns. our examination also shows that the AW warming and cooling is also accompanied by changes in depthsof the AW upper boundary and the AW core that provides evidence for the different volume and properties of the AW during warmer and cooler phases. In this respect, the AW warming in 1950s, 1990s differs from those in during the International Polar Year 2007/2008

Abstract

The large scale features of the vertical thermohaline structures in the Arctic Ocean during 2007-2009 were considered to reveal the changes in temperature and salinity in comparison with the historical data. In general, the main features of vertical thermohaline structures have remained unchanged over the Arctic and demonstrate the frontal barrier area between Eurasian and American basins. However, the unique summer atmospheric forcing in 2007 resulted in the considerable thermohaline changes in the surface layer. The large areas of positive and negative anomalies in temperature and salinity have been formed over the Arctic Ocean. The volumetric changes in the water masses with different temperature and salinity gradation have been also observed. The volume of Atlantic Waters with temperatures above 0°C and salinity above 34,6 increased at 22% in 2007 in comparison with 1970-1979 mean. The changes in the deeper layers habe also been revealed. Thus, the volume of intermediate waters with temperatures ranged from -0,4 to 0°C and salinities above 34,6 decreased at 30% in 2007. The most saline and cold bottom waters became warmer and fresher.
