No matter how fascinating the discoveries in the field of molecular biology are, in the end it is the phenotype that matters. In this paper we pay attention to various aspects of plant phenotyping. The challenges to unravel the relationship between genotype and phenotype are discussed, as well as the case where ‘plants do not have a phenotype’. More emphasis has to be placed on automation to match the increased output in the molecular sciences with analysis of relevant traits under laboratory, greenhouse and field conditions. Currently, non-destructive measurements with cameras are becoming widely used to assess plant structural properties, but a wider range of non-invasive approaches and evaluation tools has to be developed to combine physiologically meaningful data with structural information of plants. Another field requiring major progress is the handling and processing of data. A better e-infrastructure will enable easier establishment of links between phenotypic traits and genetic data. In the final part of this paper we briefly introduce the range of contributions that form the core of a special issue of this journal on plant phenotyping.

Indoor Monitoring

The indoor microclimate of the Scrovegni Chapel in Padova (Italy) was analysed first in the ‘80s. The early study operates in the best way for what concerns the choice of measurement devices and their positioning. Starting from 1995 a Scientific-technical Board coordinates the various initiatives commissioned for the surveys of a conservation of the Scrovegni building structures and for the preservation of frescos. However only during the last ten years, the activities of the Board have been addressed also on the study of the hypogeal environments under the Chapel and in the external environment around it in order to prevent possible damage due to the presence of water which frequently submerges the floor and part of the vertical structures of the crypt (perimeter walls and brick partitions). The investigations have been therefore extended to the crypt. The present work reports the preliminary results of the cyclical survey campaign launched last year and still ongoing: passive thermographic techniques (non-invasive and non-destructive) have been used for the identification and the investigation of the relationship between the boundary seasonal thermohygrometric conditions and the rainfall variations and other exogenous phenomena related to the complex water system of the area on which the Scrovegni Chapel stands.

In his article, A. Zholkovsky discusses the contemporary detective mini-series Otlichnitsa [A Straight-A Student], which mentions O. Mandelstam’s poem for children A Galosh [Kalosha]: more than a fleeting mention, this poem prompts the characters and viewers alike to solve the mystery of its authorship. According to the show’s plot, the fact that Mandelstam penned the poem surfaces when one of the female characters confesses her involvement in his arrest. Examining this episode, Zholkovsky seeks structural parallels with the show in V. Aksyonov’s Overstocked Packaging Barrels [Zatovarennaya bochkotara] and even in B. Pasternak’s Doctor Zhivago [Doktor Zhivago]: in each of those, a member of the Soviet intelligentsia who has developed a real fascination with some unique but unattainable object is shocked to realize that the establishment have long enjoyed this exotic object without restrictions. We observe, therefore, a typical solution to the core problem of the Soviet, and more broadly, Russian cultural-political situation: the relationship between the intelligentsia and the state, and the resolution is not a confrontation, but reconciliation.

В статье исследуются события бескоролевья 1733 г. в Речи Посполитой. Согласно «трактату Левенвольде» компромиссным кандидатом на избрание монархом Речи Посполитой был португальский инфант дон Мануэль, которого предложила Австрия. Россия больше склонялась к кандидатуре «пяста». Россия оказалась не подготовленной к началу бескоролевья. Бывшие российские союзники магнаты ВКЛ рассорились с российским послом Фридрихом Казимиром Левенвольде и перешли на сторону Франции. В конце февраля 1733 г. в ВКЛ направили Юрия Ливена, который от имени российской царицы предложил поддержку в получении короны Михаилу Вишневецкому и Павлу Сангушке. Принятое на конвокационном сейме решение об избрании королем «пяста» и католика показало популярность Станислава Лещинского. В результате вслед за Австрией Россия поддержала кандидатом на корону Фридриха Августа. Магнаты ВКЛ до последнего оставались конкурентами о короне. Оппозиция Лещинскому объединилась под лозунгом защиты «вольного выбора» и поэтому в ней остались кандидаты «пясты», которые не могли уступить друг другу, и согласились на компромисс – кандидатуру Фридриха Августа. Для противодействия возможному избранию Лещинского Россия создала в ВКЛ новоградскую конфедерацию. Ее организатором стал новоградский воевода Николай Фаустин Радзивилл. Эта конфедерация становится основой Генеральной Варшавской конфедерации, которая 5 октября 1733 г. избирает королем саксонского курфюрста. The article examines the events of the «kingless» year of 1733 in the Polish-Lithuanian Commonwealth. According to the Levenwolde Treaties the compromise candidate for the Commonwealth’s throne was the Portuguese Infante Don Manuel, who’s candidacy was proposed by Austria. Russia, in turn, leaned towards the «pyasta» candidate. The Russian Empire was clearly unprepared for the start of the kingless period. Russia’s former allies – magnates of the Grand Duchy of Lithuania – came into conflict with the Russian ambassador Frederick Kazimir Levenwolde and sided with France. In late February of 1733, Empress Anna Ioanovna of Russia sent Yuri Liven to the Grand Duchy of Lithuania, who offered official support in the struggle for the crown to Mikhail Vishnevetsky and Pavel Sangushka. The electoral decision made at the Sejm proved the popularity of the «pyast» and Catholic candidates, specifically – Stanislaus Leschinsky. In turn, Russia – following Austria – showed its support for the candidacy of Frederick August. The magnates of the Grand Duchy of Lithuania remained in opposition in the crown issue until the very last. Opposition to Leschinsky was united under the motto of «free choice». For that reason, it was comprised of «pyasta» candidates, who were in a deadlock with one another, and were now ready for the compromise candidacy of Frederick Augustus. In order to counter the possible election of Leschinsky, Russia created the Novograd Confederation in the Grand Duchy of Lithuania. It was organized by the Novograd Voevoda Faustin Radzivill. This confederation became the core of the General Warsaw Confederation that – on October 5th 1733 – elected the Saxon King to the throne of the Polish-Lithuanian Commonwealth.

: Vascular diseases are the main reason for morbidity and mortality worldwide. As we know, the earlier phase of vascular diseases is endothelial dysfunction in humans, the endothelial tissues play an important role in inflammation, coagulation, and angiogenesis, via organizing ligand-receptor associations and the various mediators’ secretion. We can use many inflammatory non-invasive tests (flowmediated dilatation, epicedial fat thickness, carotid-intima media thickness, arterial stiffness and anklebrachial index) for assessing the endothelial function. In addition, many biomarkers (ischemia modified albumin, pentraxin-3, E-selectin, angiopoietin, endothelial cell specific molecule 1, asymmetrical dimethylarginine, von Willebrand factor, endothelial microparticles and endothelial progenitor cells) can be used to evaluate endothelial dysfunction. We have focused on the relationship between endothelial dysfunction and inflammatory markers of vascular disease in this review.

This volume revisits the debates and disputes known collectively in the literature on late sixteenth- and early seventeenth-century England as the ‘Archpriest Controversy’. We argue that this was an extraordinary instance of the conduct of contemporary public politics and that, in its apparent strangeness, it is in fact a guide to the ways in which contemporaries negotiated the unstable later Reformation settlement in England. The published texts which form the core of the arguments involved in this debate survive, as do several caches of manuscript material generated by the dispute. Together they tell us a good deal about the aspirations of the writers and the networks that they inhabited. They also allow us to retell the progress of the dispute both as a narrative and as an instance of contemporary public argument about topics such as the increasingly imminent royal succession, late Elizabethan puritanism, and the function of episcopacy. Our contention is that, if one takes this material seriously, it is very hard to sustain standard accounts of the accession of James VI in England as part of an almost seamless continuity of royal government, contextualized by a virtually untroubled and consensus-based Protestant account of the relationship between Church and State. Nor is it possible to maintain that by the end of Elizabeth’s reign the fraction of the national Church, separatist and otherwise, which regarded itself or was regarded by others as Catholic had been driven into irrelevance.

The accurate and high throughput quantification of nitrogen (N) content in wheat using non-destructive methods is an important step towards identifying wheat lines with high nitrogen use efficiency and informing agronomic management practices. Among various plant phenotyping methods, hyperspectral sensing has shown promise in providing accurate measurements in a fast and non-destructive manner. Past applications have utilised non-imaging instruments, such as spectrometers, while more recent approaches have expanded to hyperspectral cameras operating in different wavelength ranges and at various spectral resolutions. However, despite the success of previous hyperspectral applications, some important research questions regarding hyperspectral sensors with different wavelength centres and bandwidths remain unanswered, limiting wide application of this technology. This study evaluated the capability of hyperspectral imaging and non-imaging sensors to estimate N content in wheat leaves by comparing three hyperspectral cameras and a non-imaging spectrometer. This study answered the following questions: (1) How do hyperspectral sensors with different system setups perform when conducting proximal sensing of N in wheat leaves and what aspects have to be considered for optimal results? (2) What types of photonic detectors are most sensitive to N in wheat leaves? (3) How do the spectral resolutions of different instruments affect N measurement in wheat leaves? (4) What are the key-wavelengths with the highest correlation to N in wheat? Our study demonstrated that hyperspectral imaging systems with satisfactory system setups can be used to conduct proximal sensing of N content in wheat with sufficient accuracy. The proposed approach could reduce the need for chemical analysis of leaf tissue and lead to high-throughput estimation of N in wheat. The methodologies here could also be validated on other plants with different characteristics. The results can provide a reference for users wishing to measure N content at either plant- or leaf-scales using hyperspectral sensors.

A review of available results on non-destructive testing of physical systems, using the concept of topological sensitivity, is presented. This mathematical tool estimates the sensitivity of a set of measurements in some given sensors, distributed along the system, to defects/flaws that produce a degradation of the system. Such degradation manifests itself on the properties of the system. The good performance of this general purpose post-processing method is reviewed and illustrated in some applications involving non-destructive testing. These applications include structural health monitoring, considering both elastodynamic ultrasonic guided Lamb waves and active infrared thermography. Related methods can also be used in other fields, such as diagnosis/prognosis of engineering devices, which is also considered.

Berghia stephanieae is a stenophagous sea slug that preys upon glass anemones, such as Exaiptasia diaphana. Glass anemones host photosynthetic dinoflagellate endosymbionts that sea slugs ingest when consuming E. diaphana. However, the prevalence of these photosynthetic dinoflagellate endosymbionts in sea slugs appears to be short-lived, particularly if B.stephanieae is deprived of prey that host these microalgae (e.g., during bleaching events impacting glass anemones). In the present study, we investigated this scenario, along with food deprivation, and validated the use of a non-invasive and non-destructive approach employing chlorophyll fluorescence as a proxy to monitor the persistence of the association between sea slugs and endosymbiotic photosynthetic dinoflagellates acquired through the consumption of glass anemones. Berghia stephanieae deprived of a trophic source hosting photosynthetic dinoflagellate endosymbionts (e.g., through food deprivation or by feeding on bleached E. diaphana) showed a rapid decrease in minimum fluorescence (Fo) and photosynthetic efficiency (Fv/Fm) when compared to sea slugs fed with symbiotic anemones. A complete loss of endosymbionts was observed within 8 days, confirming that no true symbiotic association was established. The present work opens a new window of opportunity to rapidly monitor in vivo and over time the prevalence of associations between sea slugs and photosynthetic dinoflagellate endosymbionts, particularly during bleaching events that prevent sea slugs from incorporating new microalgae through trophic interactions.
