Saccharomycetales are ascomycetic yeasts and among them the genus Blastobotrys has approximately 30 known species. Blastobotrys malaysiensis is a yeast species, described from cave samples, known until then only from Malaysia. In this study, we characterize a new strain and report the second occurrence record of this species. Here, Blastobotrys malaysiensis SXS675, was collected from soil samples from a cave in the Parque Estadual de Terra Ronca (PETER) in Goiás, Brazil. Phylogenetic analyzes revealed strong support with the sequence of the species type, as well as with other species of the clade. This new record contributes by providing new molecular data for the species and expanding the knowledge of its distribution beyond the Asian continent. First record of a yeast for the American continent and its second mention for the world.

Abstract Trends of formaldehyde (HCHO) linked to anthropogenic activity over large cities located in the Asian continent are calculated for the period 2005–2019 using the Quality Assurance for Essential Climate Variables (QA4ECV) dataset from the Ozone Monitoring Instrument (OMI) aboard the Aura satellite. Contributions due to anthropogenic emissions are isolated by applying a correction based on near-surface temperature in order to account for interference from local biogenic emissions. Strong positive trends are derived over the Middle East and the Indian subcontinent (up to 3.6% yr-1 and 2.4% yr-1 respectively) where regulations of anthropogenic non-methane volatile organic compound (NMVOC) emissions are currently limited. Weaker trends are observed over cities located in China, where the air pollution action plan (2013) may have mitigated NMVOC trends early on, but targeted legislature concerning VOC emissions was only recently introduced. HCHO trends for cities located in South and Equatorial Asia are mostly not significant or very uncertain. Cities located in Taiwan and Japan (regions in Asia where legislation has been in place since the early 2000s) display mostly negative trends.

The Middle East, a Muslim majority region in the Asian continent, has remained a centre for territorial and extraterritorial powers to secure their strategic interests significantly to access oil reserves in the region. Israel and the United States are two examples respectively. In the wake of securing strategic interests, these states tried to interfere the polity of the Muslim states that infuriated most of the Muslim leaders to such an extent that they had to go for aggressive measures to negate the influence of these interest-seekers. Iran has been leading the Muslim states in the region and has strived hard for integrating Muslim leadership. During this process of regional integration, a special focus has been paid to deal Israel-an important strategic ally of the US in the region and permanent threat for the neighbouring Muslim states. The current circumstances, causes and effects are the product of Arab-Israel wars and most of these have been cashed in by Iran for the security of its interests in the region. Iran has facilitated the Muslim states, particularly Lebanon, to counter the Israeli strategies. It has erected Hezbollah-the party of God- in Lebanon whose effective presence has always restricted Israel from advancing to the region. Since its inception in 1985, Iranian backed Hezbollah has opposed the Israeli motives in the Middle East. Ideological similarities between Iran and Hezbollah have never allowed Israel to manipulate the region. Hezbollah has been in a war-like situation with Israel and has fought a couple of wars which have not only guaranteed a guard for Hezbollah’s campaign against Israel but also have paved the way for Iran to maintain hegemony in the region. This research has been conducted with a primary objective to analyse the Israel-Hezbollah conflict and the strategic approach of Iran towards the particular conflict.

We present new U–Pb age data for granitoids in the Central Sikhote–Alin orogenic belt in SE Russia, which refute the established opinion about the absence of the Late Cretaceous magmatism at the eastern margin of the Paleo-Asian continent. It was previously thought that a period of magmatic quiescence occurred from 88 to 50 Ma, related to subduction of the Paleo-Pacific Plate under the eastern margin of the Paleo-Asian continent, although this is inconsistent with evidence from the Sikhote–Alin, Sakhalin, and Japan regions. Three suites of plutonic rocks with different ages were identified in this study. The first suite has ages of 105–92 Ma and formed in a syn-orogenic setting. The second (86–83 Ma) and third (ca. 73 Ma) suites formed during the post-orogenic stage of the Sikhote–Alin orogenic belt. The second and third suites were coeval with Late Cretaceous granitoids that formed in a suprasubduction continental arc known as the Eastern Sikhote–Alin volcanic–plutonic belt (ESAVPB). However, the studied rocks are located far inland from the ESAVPB. The ages of the studied granitoids coincide with the timing of a change in the angle of convergence between the Paleo-Pacific Plate and eastern margin of the Paleo-Asian continent. This change in motion of the oceanic plate with respect to the continental plate was probably caused by a rupture in the subducted slab (i.e., a slab tear), followed by asthenospheric upwelling and partial melting of the overlying crust, which ultimately generated post-orogenic intrusive magmatism.Supplementary material:https://doi.org/10.6084/m9.figshare.c.5738616

The subject of this research is the soteriology of Amidism as a single formative force that contributed to the spread and acquisition of new features of the doctrine. The object of this research is the theory of salvation and rebirth in the Pure Land, which undergoes modification and adopts the elements of other schools and denominations. This article examines soteriology of the School of Amidism as a driving force that develops and promotes the doctrine of the Pure Land in the Far Eastern region during the Middle Ages. Comprehensive approach towards studying the system of soteriological aspects of Amidism allows comprehending the patterns of the process of establishment and strengthening of the doctrine in new sociocultural realms. An attempt is made to trace the peculiarities of the impact of other schools of Buddhism upon soteriology of Amidaist doctrine. The scientific novelty lies in the original approach towards examining the soteriological representations of the Buddhist direction. The soteriological aspects of Amidism are viewed as a single substrate, linking element, foundation for the doctrine of the Pure Land, which promotes its development and distribution on the Asian continent and neighboring states. Amidaist teaching has walked a long path, since conception of the idea of Pure Land to development of the complex doctrinal system. In the spatial context, Amidism transcends the boundaries, growing from the local belief to a major trend of Mahayana Buddhism. Soteriology of the doctrine has become the foundation, formative force, which contributed to strengthening and development of doctrine.

Abstract Energy requirements brought about by the industrialization and rapid population growth in developing countries such as Turkey have led to different processes. In particular, the inadequacy of underground sources of energy to meet the energy demand, Turkey is headed to energy imports. This situation makes Turkey dependent on outside day by day. European Union countries lacking in energy sources such as Turkey, are making various energy agreements in order to solve this problem. In these energy agreements, the source geography is the Asian continent, especially the Caucasus. Turkey, along with Russia, is the main actor on the energy route between East and West. Partnership on energy with Russia began in the 1960s has made Russia the dominant power for Turkey’s energy. This study examines the energy relationship between Turkey and Russia, where cooperation and rivalry are inevitable in terms of national and international interests. In this context, the factors that are subject to the energy relationship between the two countries were discussed in the study. The conclusion reached at the end of the study is that although the competition is at the forefront, the two countries have to cooperate as they are the main actors for the East-West energy route.

Abstract Anthropogenic emissions decreased dramatically during the COVID-19 pandemic, but its possible effect on monsoon is unclear. Based on coupled models participating in the COVID Model Intercomparison Project (COVID-MIP), we show modeling evidence that the East Asian summer monsoon (EASM) is enhanced in terms of both precipitation and circulation, and the amplitude of the forced response reaches about 1/3 of the standard deviation for interannual variability. The response of EASM to COVID-19 is consistent with the response to the removal of all anthropogenic aerosols simulated by atmospheric component models, which confirms the dominant role of the fast response to reduced aerosols. The observational evidence, i.e., the anomalously strong EASM observed in 2020 and 2021, also supports the simulated enhancement of EASM. The essential mechanism for the enhanced EASM in response to COVID-19 is the enhanced zonal thermal contrast between Asian continent and the western North Pacific in the troposphere, particularly at the upper troposphere, due to the reduced aerosol concentration over Asian continent and the associated latent heating feedback. As the enhancement of EASM is a fast response to the reduction in aerosols, the effect of COVID-19 on EASM dampens soon after the rebound of emissions based on the models participating in COVID-MIP.

The water buffalo (Bubalus bubalis), also known as the Asian buffalo, is an essential domestic bovid. Indeed, although its world population (~209 million heads) is approximately one-ninth that of cattle, the management of this species involves a larger human population than that involved with raising cattle. Compared with cattle, water buffalo have been understudied for many years, but interest in this species has been increasing, especially considering that the world population of these bovids grows every year—particularly that of the river buffalo. There are two genera of buffalo worldwide: the Syncerus (from the African continent), and the Bubalus (from the southwest Asian continent, Mediterranean area, southern America, and Australia). All species belonging to these two genera have specific chromosome numbers and shapes. Because of such features, the study of chromosomes is a fascinating biological basis for differentiating various species (and hybrids) of buffaloes and characterizing their karyotypes in evolutionary, clinical, and molecular studies. In this review, we report an update on essential cytogenetic studies in which various buffalo species were described from evolutionary, clinical, and molecular perspectives—particularly considering the river buffalo (Bubalus bubalis 2n = 50). In addition, we show new data on swamp buffalo chromosomes.

In order to determine the atmospheric input of 210Pb and seawater-dissolvable Pb in the East Sea (Japan Sea), we measured the concentrations of total 210Pb and dissolved Pb (<0.2 μm) in seawater and 210Pb and 226Ra in sinking particles. The East Sea is deep (∼3700 m) and enclosed by surrounding continents except for the shallow sills (<150 m). Since the East Sea is located off the East Asian continent under the westerlies, the concentrations of 210Pb and dissolved Pb in this sea are significantly affected by terrestrial sources through the atmosphere. The vertical profiles of total 210Pb and dissolved Pb generally showed a surface maximum and then decreased with depth. The concentrations of dissolved Pb in the surface water were 2 and 3 times higher than those in the North Pacific and North Atlantic Oceans, respectively. Using an independent box model (upper 1000 m or 2000 m), we estimate the atmospheric input of 210Pb to be 1.46 ± 0.25 dpm cm−2 y −1, which is within the range of published results from the land-based sites (0.44–4.40 dpm cm−2 y −1) in South Korea, China, and Japan. Based on this flux, the residence time of total 210Pb in the East Sea is calculated to be approximately 7.1 ± 1.6 years, which is twice lower than the previous estimation. Combining the residence time of 210Pb and the inventory of dissolved Pb, the atmospheric input of seawater-dissolvable Pb is estimated to be 0.98 ± 0.28 nmol cm−2 y −1. This flux is approximately 25% of the Pb flux through the wet deposition (acid-leachable fraction). Thus, our results suggest that the flux and fate of atmospheric Pb in the ocean can be successfully determined using an accurate mass balance model of naturally occurring 210Pb.
