description: The Kola Peninsula is one of the most explored arctic regions of Russia. It has been undergoing an intense industrial development for more than 80 years. The proximity of industrial objects that caused negative changes of different severity in the natural landscapes of the territory, along with the morphological changes of geosytems of various ranks led to formation of impacted regions. One of those regions is the Central Kol, located in the center of the peninsula near Monchegorsk and Kirovsk cities, where the industrial impact is caused by the non-ferrous metals facility “Severonikel”, part of the “Kola Mining and Metallurgical Company” and mining company “Apatit”. Over the past 20 years the negative condition of the local geosystems was partially restored by the “Kola Mining and Metallurgical Company” which took measures for manufacturing modernization and reclamation of the disturbed natural territories. It is necessary to assess these measures as the key ones for the restoration of ecological prosperity of the studied region. For this work we used literary sources, regional reviews of the natural environment condition, our own field materials and some earlier studies carried out by the Department of Environmental Management, Geographical Faculty of the Moscow State University in the central part of the Kola Peninsula. We used a number of methods, such as bioindication of atmospheric pollution (lichenand bryo-indication), comparative-geographical method, cartographical method, geochemical method and mathematical method. During the study we identified some zones in the central part of the peninsula, where the sources of industrial air pollutants affected the environmental components. Our study showed that natural ecosystems tended to self-restore in the impacted regions due to the decreasing emissions and manufacturing modernization.

description:           Στην εργασία που ακολουθεί, το κυρίαρχο θέμα θα μπορούσαμε να το συνοψίσουμε στο ερώτημα : ποια η σημασία και ποια η αντίληψη γύρω από τον όρο τοπίο σε θεσμικό επίπεδο, σε κοινωνικό επίπεδο και σχετικά με την πρακτική των αρχιτεκτόνων;
          Για να ερευνηθούν τα παραπάνω οδηγηθήκαμε στην άποψη ότι χρειάζεται να μελετήσουμε μια μεγάλη θεματική ενότητα και ένα ευρύ φάσμα παραδειγμάτων.  Επιλέξαμε το Νομό Λασιθίου και τη διαχείριση του πολιτισμικού τοπίου στην ανατολική Κρήτη ειδικότερα, μέσω των πολιτιστικών συλλόγων και των περιβαλλοντικών ομάδων.
          Με άλλα λόγια, πρόκειται να μας απασχολήσει το ζήτημα της έννοιας του τοπίου και πως αυτή γίνεται αντιληπτή σε αυτά τα τρία επίπεδα.  Πώς, γιατί σχετίζεται και ποια η αλληλεπίδραση της ταυτότητας αυτής με την αντίληψη των περιβαλλοντικών ομάδων.  Ποιες οι τάσεις οικονομίας – κοινωνίας.  Γιατί και με ποιο τρόπο οι δράσεις της κοινωνίας «ενεργοποιούν» τις ομάδες αυτές να κινηθούν, να συναινέσουν, να αντιδράσουν ή να διαμαρτυρηθούν.  Πώς δικαιολογείται η αντιμετώπισή τους αυτή, πώς το τοπίο και οι ομάδες συνεργάζονται και γιατί, ποιος ο λόγος «προστασίας» του τοπίου από αυτές τις ομάδες.
          Θα προσπαθήσουμε να εξηγήσουμε γιατί μας απασχόλησε αυτό το ζήτημα σήμερα, πως προέκυψε, που το εντοπίζουμε και ποιες οι αποχρώσεις του.

description: When inhibitory neurons constitute about 40% of neurons they could have an important antinociceptive role, as they would easily regulate the level of activity of other neurons. We consider a simple network of cortical spiking neurons with axonal conduction delays and spike timing dependent plasticity, representative of a cortical column or hypercolumn with large proportion of inhibitory neurons. Each neuron fires following a Hodgkin-Huxley like dynamics and it is interconnected randomly to other neurons. The network dynamics is investigated estimating Bandt and Pompe probability distribution function associated to the interspike intervals and taking different degrees of inter-connectivity across neurons. More specifically we take into account the fine temporal ``structures'' of the complex neuronal signals not just by using the probability distributions associated to the inter spike intervals, but instead considering much more subtle measures accounting for their causal information: the Shannon permutation entropy, Fisher permutation information and permutation statistical complexity. This allows us to investigate how the information of the system might saturate to a finite value as the degree of inter-connectivity across neurons grows, inferring the emergent dynamical properties of the system.

Η περιοχή μελέτης βρίσκεται δυτικά της Ιεράπετρας, παραπλεύρως του υφιστάμενου λιμανιού (αλιευτικό καταφύγιο), στα όρια του πολεοδομικού ιστού της πόλης.  Πρόκειται για μια έκταση «ξεχασμένη» στην άκρη της Ιεράπετρας, παρόλο που έχουν υλοποιηθεί κάποια έργα εκεί, όπως η κατασκευή της Ναυμαχίας (έργο της δεκαετίας του ‘90, για την ανάδειξη και αποκατάσταση ιστορικών μνημείων) και το πάρκο κυκλοφοριακής αγωγής στο οποίο δεν έχει δοθεί ιδιαίτερη σημασία με αποτέλεσμα να μη χρησιμοποιείται ουσιαστικά. Ο στόχος της συγκεκριμένης μελέτης έγκειται στην ικανότητα να οργανώσει και να βελτιώσει τη σχέση των κατοίκων της περιοχής με το κοντινό τους περιβάλλον.  Επιπλέον προσπαθεί να ενώσει την πόλη, τη θάλασσα και τους κατοίκους με την δημιουργία εγκαταστάσεων οι οποίες σκοπό έχουν να θεωρηθούν τοπόσημο για την ευρύτερη περιοχή.  Το έργο επικεντρώνεται στην οργάνωση αθλητικών εγκαταστάσεων που έχουν σχέση με το υγρό στοιχείο, ούτως ώστε, στη συγκεκριμένη παραθαλάσσια πόλη, η ενασχόληση με τη θάλασσα να γίνει σημαντική, ιδιαίτερη και απαραίτητη, λόγω της γεωγραφικής θέσης της Ιεράπετρας.

description: В работе рассмотрены эколого-географические предпосылки распространения лихорадки Западного Нила (ЛЗН) в России. Проведен анализ ситуации по ЛЗН в России, выделены регионы с частой регистрацией болезни и оценен вклад географических факторов в ее распространение с учетом влияния городской среды. Оценка пригодности климатических условий для передачи вируса Западного Нила (ВЗН) проведена методом сумм эффективных температур. Роль отдельных географических факторов выявлена методом оценки максимальной энтропии для территории Волгограда. На территории активной циркуляции ВЗН и частого инфицирования ЛЗН отмечен рост суммы эффективных температур без увеличения продолжительности сезона эффективной заражаемости комаров. Такая ситуация создает благоприятные условия для развития вируса. С ростом суммы температур циркуляция вируса идет эффективнее. Моделирование вклада природных и социальных факторов в распространение ЛЗН на примере Волгограда позволяет выделить окраинные части города, застроенные частными домами и расположенные вдоль балок и рек, заросших высоким тростником, как наиболее вероятные места инфицирования ВЗН. Данные районы содержат разнообразные местообитания для переносчиков вируса – комаров, и для носителей вируса – птиц, что приводит к активной циркуляции возбудителя.

Территория отличается неоднородностью растительного и почвенного покрова, обусловленной многообразием условий формирования. Главный массив состоит из двух параллельных макросклонов: северного и южного, которые отличаются структурой высотной поясности. Особый интерес к изучению высотно-поясной дифференциации северного макросклона возник в результате накопления достаточного фактического материала для анализа пространственных закономерностей почвенно-растительного покрова горного хребта и получения более полной картины высотной поясности. Выделены высотные пояса: высокогорный нивально-скальный пояс с подпоясами ледников и скал, и криопетрофитных группировок; горно-луговой и лугово-степной альпийский пояс; горно-луговой и лугово-степной субальпийский пояс; пояс темнохвойных лесов и лугов; пояс мелколиственных лесов; пояс горных степей с подпоясами луговых, настоящих и опустыненных степей; пояс предгорных пустынь. Для каждого пояса приведена характеристика растительного и почвенного покрова. Выявленные закономерности высотного распределения почвенно-растительного покрова северного макросклона Жетысуского Алатау могут быть использованы для дробного ботанико-географического районирования, оценки экосистемного разнообразия и его распределения по высотному градиенту, для повышения эффективности природоохранных мероприятий в период изменения климата и оценки угроз, возникающих в результате антропогенных и природных воздействий.

description: Zhetysu (Dzungarian) Alatau is a wide mountain range in the southeast of Kazakhstan, between the deserts of Turan in Kazakhstan and Central Asia, and the deserts of Dzungaria in Central Asia. The vegetation and soil cover of this region is heterogeneous due to the diversity of their formation conditions. The main ridge is combined with two parallel macroslopes, the northern and southern, with different structure of altitudinal zonation. Due to the vast amount of factual data required for analysis of the spatial patterns of the soil and vegetation cover on the ridge, and for construction of a wholesome picture of its altitudinal zones, we took a particular interest in the study of the altitudinal differentiation of the northern macroslope. We distinguished the following zones: mountainous nival-rocky with the subbelts of glaciers, rocks and cryopetrophytic groups; mountain meadow and meadow steppe alpine; mountain meadow and meadow steppe subalpine; dark coniferous forests and meadows; small-leaved forests; mountain steppe with the subbelts of meadow, typical and desert steppes; piedmont deserts. We provide the vegetation and soil cover characteristics for each belt. The revealed patterns of the altitudinal distribution of the soil and vegetation cover of the northern macroslope of the Zhetysu Alatau can be used to carry out a fractional botanical and geographical zonation, evaluate the ecosystem diversity and its distribution throughout the altitudes, improve efficiency of the measures for nature protection during the period of climate changes, as well as to assess the threats caused by the anthropogenic and natural impacts.

description: We demonstrated a method to probe local electronic states and energy relaxation in quantum Hall edge states utilizing quantum point contacts. We evaluated relaxation lengths in two cases; first, with electron tunneling, and second, only with energy exchange without tunneling between edge states. The results were consistent with previous experiments and validated our method with quantum point contacts. We applied this method to measure the energy relaxation length around a hotspot in quantum Hall regimes and revealed the possible short-distance relaxation process to be the relaxation due to energy exchange between edge states without electron tunneling.

description: Трансформация лесных экосистем выражается в сокращении покрытой лесом площади, фрагментации лесных массивов, изменении структуры и породного состава. В лесостепной зоне сплошной лесной покров отсутствует. Характерны островные массивы лесов различной площади, приуроченные к разным элементам рельефа. В условиях неустойчивого увлажнения основными факторами распределения растительных сообществ становятся рельеф и лесообразующие породы. На территории Приволжской возвышенности эти факторы выражены наиболее отчетливо. Многообразие условий местопроизрастания обуславливает существование в пределах небольшой территории лесных сообществ таежного типа, массивов широколиственных лесов, а также фрагментов остепненных и степных лесов. Столь пестрая картина осложнена коренным преобразованием большинства лесных сообществ деятельностью человека. Сокращение лесной площади и связанная и ним фрагментация лесного покрова в зоне лесостепи вызывает необходимость выделения типов массивов, сформировавшихся в результате дробления более крупных комплексов. В работе приведены данные по лесистости исследованной территории, категориям земель лесного фонда и видовому составу древостоев, описаны типы лесных массивов, характерные для зоны лесостепи. Применение методов ландшафтной экологии в сочетании использованием данных лесоустройства позволило оценить пространственную структуру лесного покрова и особенности распределения лесов по территории. Лесные массивы рассматриваются как комплексы экосистем различной степени сложности. Типы лесных массивов описаны с использованием таксационных описаний и разнообразных картографических материалов. При этом учитывалась как приуроченность к элементам рельефа, так и размеры отдельных участков. Приводится оценка видового состава основных лесообразующих пород в различных типах лесных массивов. Сопоставление характеристик лесных массивов различных типов и размеров позволило оценить их современное состояние и определить степень трансформации лесного покрова территории в целом.

description: We have performed high-field magnetization and ESR measurements on Ba$_3$CoSb$_2$O$_9$ single crystals, as a representative two-dimensional spin-1/2 Heisenberg antiferromagnet on a uniform triangular lattice, and have determined all the magnetic parameters. For an applied magnetic field $H$ parallel to the $ab$-plane, the entire magnetization curve including the plateau at one-third of the saturation magnetization ($M_\mathrm{s}$) is in excellent agreement with the results of theoretical calculations except an anomaly near $(3/5)M_\mathrm{s}$, indicative of an additional field-induced transition. However, for $H\,{\parallel}\,c$, the magnetization curve exhibits a cusp near $M_\mathrm{s}/3$. Paramagnetic resonance signals above the Néel temperature indicate the nearly isotropic $g$-factor. A detailed analysis of the collective ESR modes observed in the ordered state, combined with the magnetization process, provides evidence of the weak easy-plane anisotropy.

description: Even when robust competition becomes institutionalized for national elections in democracies, this is no guarantee that elections to subnational governments will be equally competitive there. This article documents a recent disconcerting worldwide return of “silent elections'' - electoral races in which citizens are unable to choose among political alternatives and their vote makes no difference to the outcome. Holding such uncontested elections clashes simultaneously with the dual dimensions of democratic government: contestation and inclusiveness. Eliminating any contestation whatsoever not only skews democratic representation but is also expected to have a devastating effect on citizen participation. Leveraging a large dataset of 6,254 Czech municipalities in seven municipal elections between 1998 and 2022, the main contributions of this article are assessing the extent of the problem of silent elections over time, understanding its root causes, estimating its effect on turnout and exploring what mechanisms drive the nexus between uncontested elections and voter participation. The steady rise in the proportion of uncontested races (28% of all municipalities by 2022) as well as their staggering and increasing estimated effect on turnout (17 points relative to contested) point towards a thus far unnoticed deficit of local democracy.

description: The instrumental use of patronage for political appointments and career advancement can be found across all regime types and historical periods. Despite a pronounced academic interest in the political and economic effects of patron-client relationships, little is known about the nature of interplay between informal networks and formal hierarchies. How are formal powers distributed in personalized bureaucracies? The article addresses this question through a cross-temporal case study of subnational government in one of Russia’s regions – Sverdlovsk Oblast. Based on network analysis and negative binomial regression, the article shows that subnational leaders and their clienteles seek to monopolize those formal powers that allow administrative control over other executive agencies, while other coercive, financial, and normative powers are distributed relatively evenly. This pattern persists regardless of institutional context, degree of subnational autonomy, or the shape of informal networks, which signifies the importance of controlling functions that the core of informal networks in personalized bureaucracies performs.

description: Большинство болот и многие заболоченные земли в Московской области претерпели полную хозяйственную трансформацию, пик которой пришёлся на 1920-1980-х гг. Сильному воздействию подверглись долины рек, где русла были зарегулированы для эффективного сброса избытка воды из дренажных систем. Проблемы деградации экосистем осушенных торфяников и окружающих их территорий, на которые это осушение влияет, поставили задачи обводнения и дальнейшей экологической реабилитации. Это важно для борьбы с тростниковыми и торфяными пожарами и для сохранения биоразнообразия на ООПТ и окружающих их осушенных торфяниках, подверженных этим пожарам. Исследования проводились в Талдомском городском округе Московской области в 2001-2020 гг. в Дубненском болотном массиве. В этот период здесь были реализованы проекты по удержанию воды на нарушенных участках поймы р. Дубны. Финансовую поддержку проекту оказал фонд Манфреда Хермсена (Германия). Одним из видов-индикаторов состояния водно-болотных экосистем является серый журавль, так как гнездование этого вида находится в тесной зависимости от гидрологических условий. В 2020 г. в пойме р. Дубны отмечено увеличение численности гнездовой популяции. Этому способствуют климатические изменения, в результате которых увеличивается заболачиваемость долинных территорий и повышается, стабилизируясь, уровень безнапорных грунтовых вод. Появление территориальных пар серого журавля в гнездовой период и ночёвочных стаций в осенний период на обводнённом участке пойменных болот, где журавли ранее не отмечались, указывает на эффективность принятых мер по удержанию воды в старичных озёрах р. Дубны путём строительства дамб. Изучение динамики распределения территориальных пар серых журавлей в водно-болотных ландшафтах даёт возможность делать выводы об изменениях условий среды и прогнозировать изменения состава животного населения для решения проблемы управления водно-болотными экосистемами для сохранения их биоразнообразия.

description: The proliferation of democratic rule in Africa has been accompanied by external involvement in fostering democracy. The African Union along with various regional organizations have included clauses in their treaties calling for member-state adherence to democratic governance. Moreover, African regional organizations have used punishments such as membership suspension, sanctions, and military force to motivate states experiencing democratic reversals to change course. However, despite these trends, there has been no investigation into how Africans perceive external involvement in fostering democracy. This study remedies this gap by evaluating public attitudes toward such external pressure using the sixth round of the Afrobarometer survey. Specifically, the study explores how individual assessment of electoral practice and a country's and its neighbours' history of unconstitutional changes of government influence approval of external democracy promotion. This article lays the foundation for further investigating the roots of legitimacy of actions taken by international organizations aimed at promoting good governance and democracy.

description: We report angle-resolved photoemission spectroscopy (ARPES) results of A-site ordered perovskite CaCu$_3$Ti$_4$O$_{12}$. We have observed the clear band dispersions, which are shifted to the higher energy by 1.7 eV and show the band narrowing around 2 eV in comparison with the local density approximation calculations. In addition, the high energy multiplet structures of Cu 3$d^8$ final-states have been found around 8 - 13 eV. These results reveal that CaCu$_3$Ti$_4$O$_{12}$ is a Mott-type insulator caused by the strong correlation effects of the Cu 3$d$ electrons well hybridized with O 2$p$ states. Unexpectedly, there exist a very small spectral weight at the Fermi level in the insulator phase, indicating the existence of isolated metallic states.

description: Civil society is a bulwark against autocratic rule; its erosion contributes to democratic recession worldwide. Scholars and activists are calling attention to repressive laws non-democratic governments enact to undermine civil society organizations (CSOs). Yet, non-democratic governments do not only enact repressive laws; they also enact permissive, quasi-democratic legal rules. Evidence from case studies suggests that non-democratic governments enact such rules as part of a broader strategy to stabilize the regime. This article adds a within-case comparative study of Kenya’s four CSO regulators to the growing evidence showing that non-democracies can choose to manipulate civil society rather than repress it. The government’s words and documentation provide evidence: I triangulate elite interviews with elected officials and bureaucrats with archival data from government libraries and four CSO regulators. I find that the government enacts permissive legal rules and then uses several control and consultation tactics collectively, separately, and episodically to manipulate CSOs and legitimise the regime.
Where Does Black Hole Entropy Lie? Some Remarks on Area-Entropy Law, Holographic Principle and Noncommutative Space-Time

description: In confrontation with serious and fundamental problems towards ultimate theory of quantum gravity and physics of Planck scale, we emphasize the importance of underlying noncommutative space-time such as Snyder's or Yang's Lorentz-covariant quantized space-time. The background of Bekenstein-Hawking's Area-entropy law and Holographic principle is now substantially understood in terms of {\it Kinematical} Holographic Relation [KHR], which holds in Yang's quantized space-time as the result of the kinematical reduction of spatial degrees of freedom caused by its own nature of noncommutative geometry.

description: The proliferation of democratic rule in Africa has been accompanied by external involvement in fostering democracy. The African Union along with various regional organizations have included clauses in their treaties calling for member-state adherence to democratic governance. Moreover, African regional organizations have used punishments such as membership suspension, sanctions, and military force to motivate states experiencing democratic reversals to change course. However, despite these trends, there has been no investigation into how Africans perceive external involvement in fostering democracy. This study remedies this gap by evaluating public attitudes towards such external pressure using the sixth round of the Afrobarometer survey. Specifically, the study explores how individual assessment of electoral practice and a country’ sand its neighbours' history of unconstitutional changes of government influence approval of external democracy promotion. This article lays the foundation for further investigating the roots of legitimacy of actions taken by international organizations aimed at promoting good governance and democracy.

description: Most of the bogs and bogged lands of the Moscow Region have been fully transformed with agricultural activities that reached their highest point the 1920-1980s. It heavily impacted the river valleys, where the river beds were regulated to ensure an effective discharge of the excess water from the drainage systems. Due to the problems of ecosystems degradation in the drained peat bogs and the adjacent territories that are affected by this drainage, the flooding and further ecological rehabilitation shall be performed in this territory. This task is important for fire control in the reeds and peat bogs and for the preservation of biodiversity in the specially protected nature territories and the surrounding drained peat bogs that are subjects to these fires. Our studies were carried out in the Taldom Urban District of the Moscow Region in 2001-2020 in the Dubna bog massif. During this period the projects to keep water in the disturbed areas of the Dubna floodplain were implemented there. The projects were financed by the Manfred Hermsen Foundation (Germany). The common crane is one of the indicator species of the state of wetland ecosystems, because it nests depending on the hydrological conditions. During 2020 in the Dubna floodplain we registered an increase in the number of its breeding population due to the climate changes that cause an increased bogging in the valley territories and the growth and stabilization of the free-flow groundwater level. The occurrences of territorial pairs of the common crane during their nesting period and roosting stations during autumn period in the flooded area of the floodplain bogs, where these birds have not been registered before, indicates that building of the dams to keep water in the oxbow lakes of the Dubna River was an effective measure. By studying the distribution dynamics of the common crane’s territorial pairs throughout the wetland landscapes, we can make conclusions about environmental changes and predict changes in the species composition of animal population to solve management problems of wetland ecosystems for preservation of their biodiversity.

description: To understand the origin of the nodal gap structure realized in BaFe$_2$(As,P)$_2$, we study the three-dimensional gap structure based on the three-dimensional ten-orbital Hubbard model with quadrupole interaction. In this model, strong spin and orbital fluctuations develop by using the random-phase-approximation. By solving the Eliashberg gap equation, we obtain the fully-gapped s-wave state with (without) sign reversal between hole-like and electron-like Fermi surfaces due to strong spin (orbital) fluctuations, so called the $s_\pm$-wave ($s_{++}$-wave) state. When both spin and orbital fluctuations strongly develop, which will be realized near the orthorhombic phase, we obtain the nodal s-wave state in the crossover region between $s_{++}$-wave and $s_\pm$-wave states. The obtained nodal s-wave state possesses the loop-shape nodes on electron-like Fermi surfaces, due to the competition between attractive and repulsive interactions in k-space. In contrast, the SC gaps on the hole-like Fermi surfaces are fully-gapped due to orbital fluctuations. The present study explains the main characters of the anisotropic gap structure in BaFe$_2$(As,P)$_2$ observed experimentally.

description: We experimentally demonstrate the occurrence of various synchronized states in coupled piece-wise linear time-delayed electronic circuits using dynamic environment coupling where the environment has its own intrinsic dynamics via feedback from the circuits. We carry out these experiments in two different coupling configurations, namely mutual and subsystem coupling configurations. Depending upon the coupling strength and the nature of feedback, we observe a transition from nonsynchronization to complete synchronization via phase synchronization and from nonsynchronization to inverse synchronization via inverse-phase synchronization between the circuits in hyperchaotic regime. Snapshots of the time evolution, phase projection plots and localized sets of the circuits as observed experimentally from the oscilloscope, along with supporting numerical simulations confirm the existence of different synchronized states. Further, the transition to different synchronized states can be verified from the changes in the largest Lyapunov exponents, Correlation of Probability of Recurrence and Correlation Coefficient as a function of the coupling strength. We present a detailed linear stability analysis and obtain conditions for different synchronized states.

description: In quantum wires, the hyperfine coupling between conduction electrons and nuclear spins can lead to a (partial) ordering of both of them at low temperatures. By an interaction-enhanced mechanism, the nuclear spin order, caused by RKKY exchange, acts back onto the electrons and gaps out part of their spectrum. In wires with two subbands characterized by distinct Fermi momenta kF1 and kF2, the nuclear spins form a superposition of two helices with pitches π/kF1 and π/kF2, thus exhibiting a beating pattern. This order results in a reduction of the electronic conductance in two steps upon lowering the temperature.

description: Τα κονιάματα έχουν ενσωματωθεί στην κατασκευή τοιχοποιίας εδω και πολλές χιλιάδες χρόνια και χρησιμοποιούνται ανεξάρτητα σε πολλές περιοχές του κόσμου. Σημαντικές εξελίξεις στην τεχνολογία κονιάματος πραγματοποιήθηκαν στην Ευρώπη κατά την κλασσική ελληνική και ρωμαϊκή εποχή, ιδιαίτερα με τη συστηματική χρήση της ποζολάνης μαζί με τον ασβέστη για την παραγωγή υδραυλικών κονιαμάτων με αυξημένη αντοχή.
Τα κονιάματα που βασίζονται στη χρήση ασβέστη ως συνδετικό απαντώνται ανά τον κόσμο σε δομές που κυμαίνονται από τεράστιες αμυντικές τοιχοποιές, οικιστικά και τελετουργικά κτίρια έως μικρές κατασκευές. Μετά την αναγέννηση και το 18-19ο αιώνα της βιομηχανικής επανάστασης, παρατηρούνται τεχνολογκές εξελίξεις οι οποίες κορυφώθηκαν με τα φυσικά και
τεχνητά υδραυλικά συνδετικά συαστατικά, που προέρχονται από την όπτηση ασβεστόλιθων που περιέχουν ήδη αργιλοπυριτικές ενώσεις ή προστίθεται επί τούτου ειδικό πηλόχωμα. Στις αρχές του 19ου αιώνα, το τσιμέντο Portland κατοχυρώθηκε με δίπλωμα ευρεσιτεχνίας και ακολούθως αναπτύχθηκε στο υλικό που χρησιμοποιούμε σήμερα, που συνδέεται με την παγκοσμιοποιημένη εκβιομηχάνιση. Οι εξελίξεις με την πάροδο του χρόνου έχουν οδηγήσει
σε μια μεγάλη ποικιλία κονιαμάτων που χρησιμοποιούνται σε αποκαταστάσεις παλαιότερων κτιρίων. Τα ιστορικά κτίσματα απαιτούν επομένως την συμβατότητα των κονιαμάτων τους, για αποτελεσματική συντήρηση και θετική παρέμβαση για τη διασφάλιση της μελλοντικής βιωσιμότητάς τους.
Σήμερα η χρήση τσιμέντου ως συνδετικού υλικού σε τοιχοποιίες, αν και εκτεταμένη στο παρελθόν αναγνωρίζεται ότι προκαλεί έντονα προβλήματα φθοράς, κυρίως λόγω ασυμβατότητας με τα παραδοσιακά δομικά υλικά. Επομένως λόγω των πολλών μειονεκτημάτων του τσιμέντου που έχουν αναλυθεί στην εργασία, θα ασχοληθουμε με τη μελέτη έτοιμων κονιαμάτων του εμπορίου χωρίς τσιμέντο.
Συγκεκριμένα στην εργασία μελετώνται παραδοσιακά κονιαμάτα του εμπορίου (με βάση την άσβεστο, υδραυλική άσβεστο, ποζολανών) σε Ελλάδα και Ευρώπη και στη συνέχεια γίνεται μια αναφορά στα σύγχρονα πρόσθετα (modern additives).
Έπειτα παρουσιάζονται συγκεντρωτικοί πίνακες για κάθε κατηγορία κονιάματος με τα τεχνικά χαρασκτηριστικά τους και εφαρμογές σύμφωνα με τα οποία οδηγούμαστε στην πρόταση συμβατών κονιαμάτων αποκατάστασης κτιρίων. Με αυτόν τον τροπό δίνουμε την δυνατότητα στον κατασκευαστή (καταναλωτή) να επιλέξει απο μια σειρά προϊόντων (κατάλογο) διάφορων εταιρειών το καλύτερο κονίαμα ανάλογα την χρήση που το θέλει.

description: A method to calculate the crystal field parameters {\it ab initio} is proposed and applied to trivalent rare earth impurities in yttrium aluminate and to Tb$^{3+}$ ion in TbAlO$_3$. To determine crystal field parameters local Hamiltonian expressed in basis of Wannier functions is expanded in a series of spherical tensor operators. Wannier functions are obtained by transforming the Bloch functions calculated using the density functional theory based program. The results show that the crystal field is continuously decreasing as the number of $4f$ electrons increases and that the hybridization of $4f$ states with the states of oxygen ligands is important. Theory is confronted with experiment for Nd$^{3+}$ and Er$^{3+}$ ions in YAlO$_3$ and for Tb$^{3+}$ ion in TbAlO$_3$ and a fair agreement is found.

Dark Radiation or Warm Dark Matter from long lived particle decays in the light of Planck

description: Although Planck data supports the standard ΛCDM model, it still allows for the presence of Dark Radiation corresponding up to about half an extra standard neutrino species. We propose a scenario for obtaining a fractional "effective neutrino species" from a thermally produced particle which decays into a much lighter stable relic plus standard fermions. At lifetimes much longer than 1 sec, both the relic particles and the non-thermal neutrino component contribute to Dark Radiation. By increasing the stable-to-unstable particle mass ratio, the relic particle no longer acts as Dark Radiation but instead becomes a candidate for Warm Dark Matter with mass O(1keV - 100GeV). In both cases it is possible to address the lithium problem.
