Wedding Music

This chapter presents an overview of music written by 23 composers representative of a larger repertoire written about 1715 to 1760 for the Baroque clarinet. The works examined include opera, cantata, duos, concertos, wedding music, chamber music, military music, sacred arias, requiem, and motets by Dreux, Vivaldi, Caldara, Faber, Telemann, Handel, Chinzer, Rathgeber, Münster, Glaser, Kölbel, Molter, Sparry, Rameau, Zach, Stark, Johann Stamitz, Graupner, d’Herbain, Pasterwiz, La Borde, Ulbrecht, and Arne. The music is written in a trumpet style characterized by repeated notes, incomplete arpeggios, fanfare motives, limited range, and restricted use of the low register. In works composed after about 1730, a lyrical style of melodic writing takes on a greater importance with scale passages, leaps of an octave or more, and more frequent use of the low register.

Remarkable Agreement

Convergent-beam electron diffraction (CBED) patterns contain an immense amount of information relating to the structure of the material from which they are obtained. The analysis of these patterns has progressed to the point that under appropriate, well specified conditions, the intensity variation within the CBED discs may be understood in a quantitative sense. Rossouw et al for example, have produced numerical simulations of zone-axis CBED patterns which show remarkable agreement with experimental patterns. Spence and co-workers have obtained the structure factor parameters for lowindex reflections using the intensity variation in 2-beam CBED patterns. Both of these examples involve the use of digital data. Perhaps the most frequent use for quantitative CBED analysis is the thickness determination described by Kelly et al. This analysis has been implemented in a variety of different ways; from real-time, in-situ analysis using the microscope controls, to measurements of photographic prints with a ruler, to automated processing of digitally acquired images. The potential advantages of this latter process will be presented.

Computer Assisted Image

The polarized light microscope has the unique potential to measure submicroscopic molecular arrangements dynamically and non-destructively in living cells and other specimens. With the traditional pol-scope, however, single images display only those anisotropic structures that have a limited range of orientations with respect to the polarization axes of the microscope. Furthermore, rapid measurements are restricted to a single image point or single area that exhibits uniform birefringence or other form of optical anisotropy, while measurements comparing several image points take an inordinately long time.We are developing a new kind of polarized light microscope which combines speed and high resolution in its measurement of the specimen anisotropy, irrespective of its orientation. The design of the new pol-scope is based on the traditional polarized light microscope with two essential modifications: circular polarizers replace linear polarizers and two electro-optical modulators replace the traditional compensator. A video camera and computer assisted image analysis provide measurements of specimen anisotropy in rapid succession for all points of the image comprising the field of view.

Abstract The primary function of the acetabular labrum, like that of the glenoid, is to deepen the socket and improve joint stability. Tears of the acetabular labrum are common in older adults but occur in all age groups and with equal frequency in males and females. The AMA Guides to the Evaluation of Permanent Impairment (AMA Guides), Fifth Edition, is silent about rating tears, partial or complete excision, or repair of the acetabular labrum. Provocative tests to detect acetabular labrum tears involve hip flexion and rotation; all rely on production of pain in the groin (typically), clicking, and/or locking with passive or active hip motions. Diagnostic tests or procedures rely on x-rays, conventional arthrography, computerized tomography, magnetic resonance imaging (MRI), magnetic resonance arthrography (MRA), and hip arthroscopy. Hip arthroscopy is the gold standard for diagnosis but is the most invasive and most likely to result in complications, and MRA is about three times more sensitive and accurate in detecting acetabular labral tears than MRI alone. Surgical treatment for acetabular labrum tears usually consists of arthroscopic debridement; results tend to be better in younger patients. In general, an acetabular labral tear, partial labrectomy, or labral repair warrants a rating of 2% lower extremity impairment. Evaluators should avoid double dipping (eg, using both a Diagnosis-related estimates and limited range-of-motion tests).

SummaryThyroid surgery is one of the more common surgical procedures in Germany. This is in contrast with the situation in some other countries, where this procedure is performed comparatively rarely. In this paper the number of thyroid surgeries in Germany is compared with other western countries (Netherlands, USA, England). In contrast to e. g. the USA and England the number of thyroid surgeries in Germany is declining, however with approximately 109/100 000/year in 2012 is still elevated (Netherlands: 16/100 000/year, USA: at least 42/100 000/year, England: at least 27/100 000/year).Possible contributing factors to this higher number of thyroid surgeries in Germany are explored. These factors include iodine deficiency, the frequent use of advanced diagnostics such as ultrasound, insufficient use of preoperative diagnostic measures such as fine needle biopsy and the practice of “defensive medicine”. How much each of these factors contributes is however unclear.

SummaryThe possible involvement of secreted platelet substances in agonist- induced [Ca2+]i increases was investigated by comparing these increases in aspirin-treated, fura-2-loaded normal platelets and platelets from patients with storage pool deficiencies (SPD). In the presence and absence of extracellular calcium, the [Ca2+]i response induced by 10 µM ADP, but not those induced by 0.1 unit/ml thrombin, 3.3 µM U46619, or 20 µM serotonin, was significantly greater in SPD platelets than in normal platelets, and was increased to the greatest extent in SPD patients with Hermansky-Pudlak syndrome (HPS), in whom the dense granule deficiencies are the most severe. Pre-incubation of SPD-HPS and normal platelets with 0.005-5 µM ADP produced a dose-dependent inhibition of the [Ca2+]i response induced by 10 µ M ADP, but did not alter the [Ca2+]i increases induced by thrombin or U46619. Within a limited range of ADP concentrations, the dose-inhibition curve of the [Ca2+]i response to 10 µM ADP was significantly shifted to the right in SPD-HPS platelets, indicating that pre-incubation with greater amounts of ADP were required to achieve the same extent of inhibition as in normal platelets. These results are consistent with a hypothesis that the smaller ADP-induced [Ca2+]i increases seen in normal platelets may result from prior interactions of dense granule ADP, released via leakage or low levels of activation, with membrane ADP receptors, causing receptor desensitization. Addition of apyrase to platelet-rich plasma prior to fura-2 loading increased the ADP-induced [Ca2+]i response in both normal and SPD-HPS platelets, suggesting that some release of ADP derived from both dense granule and non-granular sources occurs during in vitro fura-2 loading and platelet washing procedures. However, this [Ca2+]i response was also greater in SPD-HPS platelets when blood was collected with minimal manipulation directly into anticoagulant containing apyrase, raising the possibility that release of dense granule ADP resulting in receptor desensitization may also occur in vivo. Thus, in addition to enhancing platelet activation, dense granule ADP could also act to limit the ADP-mediated reactivity of platelets exposed in vivo to low levels of stimulation.

Background: Frozen shoulder is a condition of the shoulder joint that experiences inflammation, pain, adhesions, atrophyand shortening of the joint capsule resulting in limited motion. In frozen shoulder patients, the limited range of motion ofthe shoulder joint can affect and reduce functional ability. This study aims to analyze the correlation between the limitedarea of motion of the shoulder joint with the functional ability of frozen shoulder patients at the Medical RehabilitationInstallation Dr. Mohammad Hoesin Palembang. Methods: This study was an observational analytic study, correlationtest, with a cross sectional design. There were 29 frozen shoulder patients who met the inclusion criteria in the MedicalRehabilitation Installation Dr. Mohammad Hoesin Palembang in November 2018 was taken as a sample using consecutivesampling techniques. Functional ability was assessed using the quickDASH questionnaire and the area of motion wasmeasured using a goniometer, then analyzed. Results: The results of the correlation test showed significant resultsbetween functional abilities and the area of motion of the shoulder joints. Active flexion (p = 0.000; r = -0.669), activeextension (p = 0.004; r = -0.520), active abduction (p = 0.000; r = -0.663), active adduction (p = 0.022; r = -0.423 ), passiveflexion (p = 0.001; r = -0.589), passive extension (p = 0.002; r = -0.543), passive abduction (p = 0.000; r = -0.676), passiveadduction (p = 0.038; r = -0.388). Conclusion: There is a significant correlation between limited joint motion andfunctional ability in frozen shoulder patients at the Medical Rehabilitation Installation of Dr. Mohammad HoesinPalembang

Standing Question

This article positions Pablo Neruda's poetry collection Residence on Earth I (written between 1925–1931 and published in 1933) as a ‘text in transit’ that allows us to trace the development of transnational modernist networks through the text's protracted physical journey from British colonial Ceylon (now Sri Lanka) to Madrid, and from José Ortega y Gasset's Revista de Occidente (The Western Review) to T. S. Eliot's The Criterion. By mapping the text's diasporic movement, I seek to reinterpret its complex composition process as part of an anti-imperialist commitment that proposes a form of aesthetic solidarity with artistic modernism in Ceylon, on the one hand, and as a vehicle through which to interrogate the reception and categorisation of Latin American writers and their cultural institutions in a British periodical such as The Criterion, on the other. I conclude with an examination of Neruda's idiosyncratic Spanish translation of Joyce's Chamber Music, which was published in the Buenos Aires little magazine Poesía in 1933, positing that this translation exercise takes to further lengths his decolonising views by giving new momentum to the long-standing question of Hiberno-Latin American relations.

Besides the conventional extracorporeal circulation, commonly used in cardiac surgery, the methods of extracorporeal life support (ECLS) have been applied ever more frequently in thoracic surgery in recent years. The most commonly used modalities of such supports include extracorporeal membrane oxygenation (ECMO) and the Novalung interventional lung assist device (iLA). Successful application of ECLS has led to its more frequent use in general thoracic surgery, especially as a tool to treat hypercapnia and to ensure oxygenation and haemodynamic support. However, these methods are essential in lung transplant programmes; without their help, in most cases, it would not be possible to perform the transplantatioz or prevent the severe complications associated with critical primary graft dysfunction. Additionally, the extracorporeal circulation also facilitates the performing of specific surgical procedures that would not be feasible under standard conditions or would be associated with an inadequate risk. The application of extracorporeal life supports can fundamentally increase the level of resection when treating advanced intrathoracic malignancies that are in close contact with the heart and large vessels or even directly extend into them. Without the possibility of resecting such structures en bloc, together with the tumour, and, thus, achieving an R0 resection, these malignant tumours are often directly contraindicated for surgery or are operated non-radically, i.e. unsuccessfully. Complete tumour resection is the most important prognostic factor in the surgery.
