Based on Ehrenfried Pfeiffer's method of sensitive crystallization, the Cartographies of Metamorphosis artistic project exposes the vitality, in the form of mandala graphics, of the different horticultural products from Campo de Cartagena, a method that makes the intrinsic quality of the material visible organic. In 2016, the Mar Menor landscape collapsed for the first time and accentuated its state of environmental crisis, due in part to the dumping of large amounts of organic matter and nutrients of various kinds, but especially from agricultural and livestock activities. Made in the context of the environmental crisis of the Mar Menor, the sculptural and audiovisual installation metaphorically reflects on the new geological era coined by Paul Crutzen and the eutrophication landscape around the lagoon.

The immature epicarps of Juglans mandshurica and Juglans regia have been used as folk medicine for the treatment of cancer in China. Other parts of the J.mandshurica plant, including leaves, branches, barks, and stems, have reported antitumor activities. We previously found that various diarylheptanoids and phenolic compounds isolated from J. mandshurica epicarps show significant antitumor activities. However, there are no reports of quantitative analysis of diarylheptanoids and phenolic compounds of J. mandshurica. In this study, a validated quantitative method, based on ultraperformance liquid chromatography coupled with triple-quadrupole tandem mass spectrometry, was employed to determine the contents of eight diarylheptanoids and seven phenolic compounds in the epicarps of J. mandshurica during different growth periods, in different parts of the plant, and in the epicarps of two Juglans species. The most successful J. mandshurica epicarp harvesting time fell between Day 12 and Day 27. The leaves of J. mandshurica showed potential for medical use as they had the highest content of the 15 compounds (3.399 ± 0.013 mg/g). We showed for the first time that the total content of diarylheptanoids in J. mandshurica is higher than that in J. regia, though, conversely, J. regia has higher contents of phenolic compounds. The method developed in this study is practical and simple and can be applied for quantitative analysis for evaluating the intrinsic quality of J. mandshurica.

Abstract We empirically investigate, for the first time to the best of our knowledge, the role of economics in antitrust enforcement by EC’s Competition Authority (DGCOMP), by constructing and measuring indicators capturing the extent and type of economics used in reaching infringement decisions between 1992 and 2016. This allows us to identify the legal standards (LSs) adopted in assessing different conducts and their evolution and compare these to their theoretically optimal level, thus capturing the quality of enforcement. On average, economic analysis plays a modest role in investigations, with little analysis to substantiate consumer harm or to account for efficiencies, for conducts for which effects-based would be the appropriate LS. However, there is a consistent and significant improvement over time in the quality of enforcement in abuse of dominance cases, with effects-based LSs adopted in recent years. This contrasts to earlier findings and questions recent views, by indicating that DGCOMP has been influenced by the significant progress that economic analysis of antitrust has made in recent decades. Results on how LSs adopted affect the outcome of the judicial review (the rate of decision annulment) do not support the hypothesis that this increases as LSs move closer to effects-based.

The history of plainchant in the nineteenth century is dominated by the various attempts at scholarly restoration both in Britain and abroad. Up to the middle part of the century these efforts were concentrated in France, although demands for revival were being voiced in Italy by Pietro Alfieri, and in Germany by Franz Xaver Witt, amongst others. The first scholarly attempt at the restoration of plainchant was made in 1846 as a result of Jean-Louis-Félix Danjou's discovery of the eleventh-century tonary of St Bénigne de Dijon. Like the Rosetta stone, it enabled scholars to decipher the meaning of symbols which had previously eluded them. In this case the manuscript is notated with both neumes and alphabetic script, so that for the first time the melodic ductus of ancient neumes could be interpreted with certainty. This manuscript became the source for the Rheims-Cambrai Graduale Romanum complectens missas, printed in Paris in 1851, later to be published under the auspices of Cardinal Sterckx of Mechelen and edited by Duval and Bogaerts. Despite the quality of the Mechlin Graduale, it did not fail to cause immense controversy. Louis Vitet, for example, ‘was astonished that a group of four notes in the Paris gradual of 1826 should be replaced in the Rheims-Cambrai edition with a melisma of 48 notes’. Other efforts at revival were equally plagued by controversy. Lambillotte's facsimile edition of St Gall 359, published, in 1851, proved to be ‘completely unreliable’, and the 1857 Parisian Graduale romanum upon which it is based ‘contained truncated melodies’.

Purpose The shortage of doctor of philosophy (PhD)–level applicants to fill academic and research positions in communication sciences and disorders (CSD) programs calls for a detailed examination of current CSD PhD educational practices and the generation of creative solutions. The intended purposes of the article are to encourage CSD faculty to examine their own PhD program practices and consider the perspectives of recent CSD PhD graduates in determining the need for possible modifications. Method The article describes the results of a survey of 240 CSD PhD graduates and their perceptions of the challenges and facilitators to completing a PhD degree; the quality of their preparation in research, teaching, and job readiness; and ways to improve PhD education. Results Two primary themes emerged from the data highlighting the need for “matchmaking.” The first time point of needed matchmaking is prior to entry among students, mentors, and expectations as well as between aspects of the program that can lead to students' success and graduation. The second important matchmaking need is between the actual PhD preparation and the realities of the graduates' career expectations, and those placed on graduates by their employers. Conclusions Within both themes, graduate's perspectives and suggestions to help guide future doctoral preparation are highlighted. The graduates' recommendations could be used by CSD PhD program faculty to enhance the quality of their program and the likelihood of student success and completion.

Recent advances made in the reuse of pulp and paper industry sludges in hardboard production are explained. Data obtained from pilot and full-scale plants using primary sludge of a pulp and paper industry as an additive in the production of hardboard is presented. An economic analysis of the reuse of pulp and paper primary sludge in hardboard manufacturing is given. The quality of the hardboard produced is tested and compared with the qualities of the hardboard produced by the same plant before the addition of primary sludge. The hardboard with primary sludge additive has been used in Turkey for about a year in the manufacturing of office and home furniture. The results are very satisfactory when the primary sludge is used at 1/4 ratio.

: Melanoma is the most life-threatening and aggressive class of skin malignancies. The incidence of melanoma has steadily increased. Metastatic melanoma is greatly resistant to standard anti-melanomatreatments such as chemotherapy, and 5-year survival rate of cases with melanoma who have metastatic form of disease is less than 10%. The contributing role of apoptosis, angiogenesis and autophagy in the pathophysiology of melanoma has been previously demonstrated. Thus, it is extremely urgent to search for complementary therapeutic approachesthat couldenhance the quality of life of subjects and reduce treatment resistance and adverse effects. Resveratrol, known as a polyphenol component present in grapes and some plants, has anti-cancer properties due to its function as an apoptosis inducer in tumor cells, and anti-angiogenic agent to prevent metastasis. However, more clinical trials should be conducted to prove resveratrol efficacy. : Herein, for first time, we summarize current knowledge of anti-cancerous activities of resveratrol in melanoma.

Abstract Background Prevalence of hearing loss increases with age. Its estimated prevalence is 40–50 % in people over 75 years of age. Recent studies agree that declinein hearing threshold contribute to deterioration in sociality, sensitivity, cognition, and quality of life for elderly subjects. The aim of the study presented in this paper is to verify whether or not rehabilitation using first time applied Hearing Aids (HA) in a cohort of old people with hearing impairment improves both speech perception in a noisy environment over time and the overall health-related quality of life. Methods The monocentric, prospective, repeated measurements, single-subject, clinical observational study is to recruit 100 older adults, first-time HA recipients (≥ 65 years).The evaluation protocol is designed to analyze changes in specific measurement tools a year after the first HA usage in comparison with the evaluation before HA fitting. Evaluations will consist of multiparametric details collected through self-report questionnaires completed by the recipients and a series of commonly used audiometric measures and geriatric assessment tools. The primary indicator of changes in speech perception in noise to be used is the Italian version of Oldenburg Satz (OLSA) test whereas the indicator of changes in overall quality of life will be the Assessment of Quality of Life (AQoL) and Hearing Handicap Inventory for the Elderly (HHIE) questionnaires. The Montreal Cognitive Assessment (MoCA) will help in screening the cognitive state of the subjects. Discussion The protocol is designed to make use of measurement tools that have already been applied to the hearing-impaired population in order to compare the effects of HA rehabilitation in the older adults immediately before first HA usage (Pre) and after 1 year of experience (Post). This broad approach will lead to a greater understanding of how useful hearing influences the quality of life in older individuals, and therefore improves potentials for healthy aging. The data is to be analyzed by using an intrasubject endpoint comparison. Outcomes will be described and analyzed in detail. Trial registration This research was retrospectively registered underno. NCT04333043at ClinicalTrials.gov (http://www.clinicaltrials.gov/) on the 26 March 2020. This research has been registered with the Ethics Committee of the Area Vasta Emilia Nord under number 104, date of approval 17/07/2017.
