AbstractA review is given of the present state of MK classification, with a view to future developments in techniques and instrumentation. The principle of the complementarity of quantitative and visual inspection techniques is stressed.Included in the discussion are examples of problems which are currently outstanding. Among these are variable stars, marginal peculiarities, fundamental standards (with specific reference to the Sun), and representation of the third and higher dimensions.

It is now possible to determine proper motions of high-velocity objects in such a way as to obtain with some accuracy the velocity vector relevant to the Sun. If a potential field of the Galaxy is assumed, one can compute an actual orbit. A determination of the velocity of the globular clusterωCentauri has recently been completed at Greenwich, and it is found that the orbit is strongly retrograde in the Galaxy. Similar calculations may be made, though with less certainty, in the case of RR Lyrae variable stars.

We do not want to place anyone into the shadow, we also claim our place in the sun.” In a foreign policy debate in the German parliament on December 6. 1897 the German Secretary of State for Foreign Affairs, Bernhard von Bülow, articulated the foreign policy aspirations of the ascendant Wilhelmine Germany. This proved easier said than done. In 1907, Eyre Crowe of the British Foreign Office penned his famous memorandum where he accounted for “the present state of British relations with France and Germany.” He concluded that Britain should meet imperial Germany with “unvarying courtesy and consideration” while maintaining “the most unbending determination to uphold British rights and interests in every part of the globe.”...

Pseudococcus calceolariae, the citrophilous mealybug, is a species of economic importance. Mating disruption (MD) is a potential control tool. During 2017–2020, trials were conducted to evaluate the potential of P. calceolariae MD in an apple and a tangerine orchard. Two pheromone doses, 6.32 g/ha (2017–2018) and 9.45 g/ha (2019–2020), were tested. The intermediate season (2018–2019) was evaluated without pheromone renewal to study the persistence of the pheromone effect. Male captures in pheromone traps, mealybug population/plant, percentage of infested fruit at harvest and mating disruption index (MDI) were recorded regularly. In both orchards, in the first season, male captures were significantly lower in MD plots compared to control plots, with an MDI > 94% in the first month after pheromone deployment. During the second season, significantly lower male captures in MD plots were still observed, with an average MDI of 80%. At the third season, male captures were again significant lower in MD than control plots shortly after pheromone applications. In both orchards, population by visual inspection and infested fruits were very low, without differences between MD and control plots. These results show the potential use of mating disruption for the control of P. calceolariae.

Our understanding of platelet functionality has undergone a sea change in the last decade. No longer are platelets viewed simply as regulators of haemostasis; they are now acknowledged to be pivotal in coordinating the inflammatory and immune responses. This expanded role for platelets brings new opportunities for controlling a range of health conditions, targeting platelet activation and their interactions with other vascular cells. Antiplatelet drugs may be of wider utility than ever expected but often cause platelet suppression too strong to be used out of clinical settings. Dietary antiplatelets represent a nutritional approach that can be efficacious while safe for general use. In this review, we discuss potential new uses for dietary antiplatelets outside the field of cardiovascular health, with specific reference to the water-soluble tomato extract Fruitflow®. Its uses in different aspects of inflammation and immune function are discussed, highlighting exercise-induced inflammation, mediating the effects of air pollution, and controlling thrombotic aspects of the immune response. Potential future developments in women’s health, erectile dysfunction, and the allergic response indicate how broad the utility of dietary antiplatelets can be.

Abstract Background This study was done to observe the incidence of Osteo-line on the femur neck and to explore the clinical application of Osteo-line in osteotomy. Methods Eighty-nine adult femur specimens were selected to observe the incidence of Osteo-line on the femur neck. From August 2015 to January 2019, a total of 278 patients who completed unilateral hip arthroplasty at the Third Hospital of Hebei Medical University were retrospectively included. Patients who accepted osteotomy via Osteo-line on the femur neck were defined as the experimental group (n = 139), and patients who accepted osteotomy via traditional method (The femoral distance 1.5 cm above the trochanter was retained for osteotomy by visual inspection.) were defined as the control group (n = 139). According to the postoperative pelvic X-ray, Photoshop was used to evaluate the leg length discrepancy (LLD) by the CFR-T-LT method. Results Among the 89 specimens, the incidence of anterior Osteo-line was 75.28%, and the incidence of posterior Osteo-line was 100%. According to the clinical application results, the incidence of anterior Osteo-line on the femur neck was 80%, and the incidence of posterior Osteo-line was 100%. The Osteo-line was clearer than those on the femoral specimens. Twenty-six cases had LLD greater than 1 cm (9.29%), including 2 cases in the experimental group and 24 cases in the control group. The average postoperative LLD in the experimental group (0.19 ± 0.38 mm) was significantly shorter than in the control group (0.54 ± 0.51 mm)(P = 0.005). Conclusion The incidence of Osteo-line on the femur neck was high, and patients who accepted osteotomy via Osteo-line on the femur neck can achieve shorter postoperative LLD than the control group.

AbstractAfter preparing a detailed new edition of Sappho’s frr. 95 and 96 V., continuously transmitted in the parchment codex P. Berol. 9722, the author proposes that they constitute a ‘cycle’ of three homometric poems with a common theme articulated in successive episodes (i. 95, ii. 96.1–20, iii. 96.21–36). In the first, Sappho conveys her despair for her separation from her beloved pupils, Arignota being one of them. In the second, Arignota is presented in Sardis, where she excels among the Lydian women. She expresses a strong feeling of nostalgia for her stay in Lesbos with Sappho and for her beloved friend there, Atthis. In the third, Sappho addresses Atthis and, employing the mythological exemplum of Aphrodite’s love to Adonis and their distant meetings, declares that they will sail to the port of Geraistion in Asia Minor’s Aegean coast, whence they will travel to Sardis for meeting their old friend. The author also meditates on the possibility that the name Ἀριγνώτα (= ‘One-easy-to-be-known, Easy-to-identify’), is a renaming by Sappho of Ἀρύηνιc, the daughter of the Lydian king Alyattes, who is yearning to see her old teacher and her childhood girlfriend before her marriage to Astyages, son of Kyaxares, king of the Medes. The marriage was negotiated for ending a many years war between the two nations, a peace that coincided with the eclipse of the sun, usually dated on May 28, 585 BC.

ABSTRACT The Kepler spacecraft observed the hot subdwarf star PHL 417 during its extended K2 mission, and the high-precision photometric light curve reveals the presence of 17 pulsation modes with periods between 38 and 105 min. From follow-up ground-based spectroscopy, we find that the object has a relatively high temperature of 35 600 K, a surface gravity of $\log g / {\rm cm\, s^{-2}}\, =\, 5.75$ and a supersolar helium abundance. Remarkably, it also shows strong zirconium lines corresponding to an apparent +3.9 dex overabundance compared with the Sun. These properties clearly identify this object as the third member of the rare group of pulsating heavy-metal stars, the V366-Aquarii pulsators. These stars are intriguing in that the pulsations are inconsistent with the standard models for pulsations in hot subdwarfs, which predicts that they should display short-period pulsations rather than the observed longer periods. We perform a stability analysis of the pulsation modes based on data from two campaigns with K2. The highest amplitude mode is found to be stable with a period drift, $\dot{P}$, of less than 1.1 × 10−9 s s−1. This result rules out pulsations driven during the rapid stages of helium flash ignition.

Squamous cell carcinomas are often seen on the sun-exposed areas of the skin and are rarely observed on the digits of the foot. However, there have been incidences of squamous cell carcinoma developing in the presence of chronic wounds with osteomyelitis, thus complicating the treatment. We present a patient with osteomyelitis who developed invasive squamous cell carcinoma of the third digit. We conclude that wounds with osteomyelitis may have underlying pathologic abnormalities that are not obvious on initial presentation.

Complete Translation

If you still haven't chosen a book to take with to the desert island, I have a suggestion: L'encyclopédie du ciel. At 1,202 pages, it will keep you occupied day and night: what you read as text by day will help you read by night in the sky. This wonderful and extremely useful book is as difficult to classify as it is to put down. Essentially, it is a compendium of Greco-Roman discourse on the stars and planets, divided into three parts. The first (‘Les images: histoire et mythologie: voir et raconter’) is about the constellations and the planets. It opens with a catalogue in which each constellation is illustrated, explained, and accompanied with appropriate quotations from Eratosthenes’ Catasterismoi and Hyginus’ Astronomica. There follow essays about the names of the constellations, on the Sun, Moon, and the planets, and one on Greek and Roman creation myths. All are accompanied by long passages of appropriate Greek and Latin texts in translation. The second part of the book (‘Les lois: l'astronomie: observer et calculer’) is about the ancient attempts to make sense of and explain the stars and planets as a system, about calendars, and about ancient astronomical instruments and objects. This part of the book also contains a complete translation of Hipparchus’ Commentary on the Phaenomena of Eudoxus and Aratus. It closes with an account of Greek star catalogues. The third part of the book is concerned with various attempts to interpret the celestial phenomena (‘Les messages: signes et influence: interpréter et prédire’). It includes, but is not restricted to, astrology; philosophical ideas are also discussed, such as astral apotheosis, the ascent of the soul through the sky, and the music of the spheres. There is a dictionary of astronomical and astrological terms and a dictionary of ancient astronomers and authors dealing with astronomy. The book closes with parallel star catalogues of Eratosthenes, Hipparchus, and Ptolemy.
