Opis:
Seasonal variability is the complex non-linear response of the physical climate system. There are two types of natural variability: those external and internal to the climate system. In any given season, natural variability may cause the climate to be different than its long-term average. This study examines with the seasonal variation of the maximum temperatures during the summer season. In addition, the maximum temperatures in May become close to the characteristics of the summer season. The monthly data for maximum temperature of May, June and July were used from Iraqi Meteorological Organization and Seismology (IMOS) for 47 years from 1970 to 2017 for Baghdad city. This period was long enough to estimate the range of approaching maximum temperature (Tmax) May to summer. Results revealed a significant Tmax for Baghdad during the second period (1992–2017) and ?shown similar behavior of Tmax in May to June and July; on the contrary that first period (1970–1991). In second period, two phases have been found out, positive phase and negative phase. The positive phase were happened in 1995, 1999, and 2006, and the negative phase was four cases (1992, 2004, 2013, and 2016), while a few cases recorded in first period. The amplitudes of monthly variability had same distance of leaner correlation especially in 1999 and 2013 that represent coherent wave with summer seasons. The variance difference for Tmax between May and June approximately was 2°C for second study’s period, while exceed this range in first period. This variance change to 7.5°C when found difference between July and May.

Opis:
Shrubs are widespread at higher altitudes and latitudes. Dendrochronology of shrub growth has been intensively studied in the circumpolar Arctic, Mediterranean and Patagonia. However, relatively little is known about shrub growth responses to climate change on the Tibetan Plateau. Herein, we investigate climate sensitivity of Salix oritrepha growth along a north–south (35–39° N) latitudinal gradient on the north- eastern Tibetan Plateau. Four S. oritrepha shrub sites were selected for dendrochronology study. Pearson and partial correlation analyses were used to estimate strength of the climate sensitivity of the growth time series at each site. We found that not all of the site chronologies show consistent variations. Despite of this, its ra- dial growth was primarily limited by the July mean temperature across the latitudinal gradient, and warming summer climate tends to increase the growth of S. oritrepha on the northeastern Tibetan Plateau.

ObjectivesThis study examined the physiological strain experienced by workers employed in motor-manual timber harvesting performed in winter and summer, and the applicability of heart rate indices for estimating energy expenditure.Material and MethodsThe heart rates (HR) of 2 teams consisting of 2 persons working simultaneously during felling and forwarding, in both winter and summer, were measured. Heart rate at work (HRwork), resting heart rate (HRrest), relative heart rate (%HRR), ratio of working heart rate to resting heart rate, and 50% level were used to estimate the physiological workload in particular jobs. The HRindex (HRwork/HRrest) equation was used to estimate the energy expenditure (EE). ResultsFor all jobs, significantly higher physiological workload and energy expenditure were recorded during winter.ConclusionsThe season significantly affects the physiological workload during logging operations. If there is no possibility of harvesting wood in summer, in order to limit the workload of workers during winter activity, attention should be paid to the proper organization of work and selection of workers.

Opis:
In this study, we examined the effect of the presence of mycorrhiza and ascomata of summer truffle (Tuber aestivum) on the bacterial composition of roots from small trees growing in selected sites of the Nida Basin. Qualitative DNA sequencing methods such as Sanger and next-generation sequencing (NGS) were used. The Sanger method revealed different bacterial species compositions between the samples where summer truffle ascomata was recorded and control samples. Five genera of bacteria could be distinguished: Bacillus, Erwinia, Pseudomonas, Rahnella and Serratia, among which the most numerous were Pseudomonas (Gammmaproteobacteria class) at 32.9%. The results obtained by the NGS method also showed differences in species composition of the bacteria depending on the study sample. Seven genera of bacteria were distinguished: Rhizorhabdus, Methylotenera, Sphingomonas, Nitrosospira, Streptomyces, Methyloceanibacter and Niastella, which dominated in roots from the truffle sites. Telmatobacter, Roseiarcus, Granulicella, Paludibaculum, Acidipila, Acidisphaera and Aliidongia dominated in roots from the control sites. With the NGS method, it is possible to identify the microbiome of a whole root, while only a root fragment can be analysed by the Sanger method. These results extend the scope of knowledge on the preferences of certain groups of bacteria associated with truffles and their influence on the formation of ascomata in summer truffles. Our results may also be useful in selecting and monitoring sites that promote ascomata of Tuber aestivum.

Warsaw Science Diplomacy School 2020 was the 1st edition of summer school held together by the European Academy of Diplomacy, based in Poland, and the European Union led programme Inventing a shared Science Diplomacy for Europe (InsSciDE). The week-long venue took place online, due to the coronavirus pandemic, between 22-26 June 2020. Class of 2020 consisted of 28 participants from 6 continents, 10 European Union member states and 27 countries in total, where vast majority possessed different nationality and country of residence. Also, the mentors and instructors of the school came from over 13 institutions gathered in the InsSciDe consortium. Participants were divided into 4 teams where they were discussing study cases of how European science diplomacy applies to global challenges. The chosen challenges were the following: Natural resources as public goods for global health; A Matter of Global Epidemic Diplomacy; Scientists in diplomacy during the Scramble for Africa; and A co-production of science and diplomacy in the Law of the Sea.

Aim. The aim of is article is to discuss how summer schools can be approached as instances of hybrid education and how this can help to address the complex needs of their participants living in a culturally and technologically intertwined world. Methodology. This paper analyses the theoretical framework of hybrid education, its manifestations in summer schools and since it needs contextualisation, how it works in a specific case of Baltic Summer University organised by Vytautas Magnus University (Kaunas, Lithuania). Research and conclusion. To reach their target audience, summer schools combine academic content, and the elements of business and entertainment. This results in a separate mode of education with new possibilities and scope, however poses a paradox: while the adoption of business and entertainment practices puts summer schools somewhat outside the realm of the traditional university practices, it makes higher education more approachable and able to react to the fast-changing reality. Baltic Summer University fits the pattern established and as such, could benefit from a more active engagement of this theoretical approach and the opportunities it offers.   Originality. While summer schools are not a particularly new phenomenon, recently this field has witnessed a great expansion in both the supply of programmes and interest from students. The nature of these programmes and sudden interest in them remains under the radar of more extensive in-depth studies, which would actually help to harness its full potential.

Opis:
From October 2002 until March 2003 surprisingly warm, oxygenated waters were frequently encountered in the Baltic Sea in the area between the Bornholm and Fårö Deeps from the halocline down to the bottom. Owing to their ventilation effect in the stagnating deep waters, their occasional observations have partly been incorrectly attributed to the inflow events of October 2002 or January 2003. The emergence of some of these waters can be traced back to the exceptional summer weather conditions in August and September 2002 in central Europe. The warm waters played a remarkable renewal pacemaker role for the subsequent important winter inflow of January 2003. The evolution of this summer inflow is described and possible causes are discussed.

Opis:
The beginning dates and the lengths of thermic seasons in Warsaw (1951-2004) were analysed. These characteristics of seasons are very variable, especially in winter. The changes of winter length influence strongly the dates and length of adjacent seasons, that is, of early winter and early spring. The current warming is best visible exactly during these seasons: winter becomes shorter, while early winter and - to an even longer degree -early spring become longer. The period of spring, summer and autumn is characterised by grater stability. These seasons showed a very weak tendency to change on even its lack, both as regards the length and the beginning date.
