Energy spectra of cosmic ray nuclei: 4z26 and .3E2 GeV/amu
Energy spectra of cosmic ray nuclei in the charge range 5 is less than or equal to z less than or equal to 26 have been derived from the response of an acrylic plastic Cerenkov detector. Data were obtained using a balloon borne detector and cover the energy range 320 is approximately less than e approximately less than 2200 MeV. amu. Spectra are derived from a formal deconvolution using the method of Lezniak (1975). Relative spectra of different elements are compared by observing charge ratios. Secondary primary ratios are observed to decrease with increasing energy, consistent with the effect previously observed at higher energy. Primary to primary ratios are constant for 6 is less than or equal to z less than or equal to 26 and 14 is less than or equal to z less than or equal to 26 but vary for 10 is less than or equal to z less than or equal to 14. This data is found to be consistent with existing data where comparable and lends strong support ot the idea of two separate source populations contributing to the cosmic ray composition

The isotopic composition of cosmic rays with 5 is less than or equal to z which is less than or equal to 26
Results obtained from a high altitude balloon flight from Thompson, Canada in August, 1973 are reported. The instrument consisted of a spark chamber, a Lucite Gerenkov counter and thirteen layers of scintillators. For heavy particles the Cerenkov-range method of analysis was used to determine the mass of particles energetic enough to produce a Cerenkov signal and then stop in the layered scintillators. The data appear to be consistent with current cosmic-ray propagation models. Using a simple exponential path length propagation model this data is extrapolated to the cosmic-ray source and some implications of the data are discussed as to the nature of the source
Bulk sensitive photo emission spectroscopy of C1b compounds
This work reports about bulk-sensitive, high energy photoelectron
spectroscopy from the valence band of CoTiSb excited by photons from 1.2 to 5
keV energy. The high energy photoelectron spectra were taken at the KMC-1 high
energy beamline of BESSY II employing the recently developed Phoibos 225 HV
analyser. The measurements show a good agreement to calculations of the
electronic structure using the LDA scheme. It is shown that the high energy
spectra reveal the bulk electronic structure better compared to low energy XPS
spectra.Comment: J. Electron Spectrosc. Relat. Phenom. accepte
The Impact of the COVID-19 Pandemic on Avoidance of Health Care, Symptom Severity, and Mental Well-Being in Patients With Coronary Artery Disease
The COVID-19 pandemic affected regular health care for patients with chronic diseases.
However, the impact of the pandemic on primary care for patients with coronary artery
disease (CAD) who are enrolled in a structured disease management program (DMP) in
Germany is not clear. We investigated whether the pandemic affected primary care and
health outcomes of DMP-CAD patients (n = 750) by using a questionnaire assessing
patients’ utilization of medical care, CAD symptoms, as well as health behavior and
mental health since March 2020. We found that out of concern about getting infected
with COVID-19, 9.1% of the patients did not consult a medical practitioner despite
having CAD symptoms. Perceived own influence on infection risk was lower and anxiety
was higher in these patients compared to symptomatic CAD patients who consulted
a physician. Among the patients who reported chest pain lasting longer than 30 min,
one third did not consult a medical practitioner subsequently. These patients were
generally more worried about COVID-19. Patients with at least one worsening CAD
symptom (chest pain, dyspnea, perspiration, or nausea without apparent reason) since
the pandemic showed more depressive symptoms, higher anxiety scores, and were less
likely to consult a doctor despite having CAD symptoms out of fear of infection. Our
results provide evidence that the majority of patients received sufficient medical care
during the COVID-19 pandemic in Germany. However, one in ten patients could be
considered particularly at risk for medical undersupply and adverse health outcomes.
The perceived infection risk with COVID-19 might have facilitated the decision not to
consult a medical doctor
The use of chemoprophylaxis in East African Zebu village cattle exposed to trypanosomiasis in Muhaka, Kenya
A study conducted to assess the efficacy of chemoprophylaxis for the improvement of the health and productivity of East African Zebu village cattle exposed to trypanosomiasis. Examines the cost-effectiveness of the treatment. Includes data on calf pre-weaning health and weight traits, weight traits of calves from 12-18 months of age, calf post-weaning health and weight traits, and breeding cow health and production traits - for the non-prophylactic and prophylactic groups
Evaluation of criteria of trypanotolerance
Evaluates teh criteria for trypanotolerance including three related characterstics, v.z. the ability to control parasitaemia, the ability to control anaemia, and the ability to develop an effective immune response
Spengler's Prussian Socialism
Oswald Spengler (1880–1936) was one of the most significant thinkers of the Weimar Republic, Germany’s first democracy. His work, notably the two-volume, 1200-page Der Untergang des Abendlandes (Decline of the West, 1918/22), had a profound influence on the intellectual discourses of the time in Germany and beyond. 1 Yet, despite the high esteem in which he was held by his contemporaries, his thought has been seriously under-researched. In English, only four major studies have appeared in the last 70 years. 2 This is all the more surprising in that the historical period in which he wrote has been extensively covered by both English- and German-language scholars and that some of the thinkers who drew critically on his ideas, such as Heidegger and Adorno, have become household names in Germany intellectual history
