Das unerwartete Ende des Obersten Arbitrage-Gerichts in Russland und die Politisierung der Justizreform

Die Auflösung des erfolgreichen Obersten Arbitrage-Gerichts Russlands1 und dessen Fusion mit dem Obersten Gericht des Landes – eine unpopuläre Maßnahme, die Wellen geschlagen hat – ist von wohlinformierten Beobachtern klar als willkürliche politische Entscheidung interpretiert worden. Sie ist in einer Reihe mit anderen Initiativen zum Gerichtswesen zu sehen, die in der jüngsten eher politischen Zwecken dienten, als dass sie die Bedürfnisse der Gerichte oder die Bestrebungen der Gerichtsreformer berücksichtigten

International cooperation for Mars exploration and sample return

The National Research Council's Space Studies Board has previously recommended that the next major phase of Mars exploration for the United States involve detailed in situ investigations of the surface of Mars and the return to earth for laboratory analysis of selected Martian surface samples. More recently, the European space science community has expressed general interest in the concept of cooperative Mars exploration and sample return. The USSR has now announced plans for a program of Mars exploration incorporating international cooperation. If the opportunity becomes available to participate in Mars exploration, interest is likely to emerge on the part of a number of other countries, such as Japan and Canada. The Space Studies Board's Committee on Cooperative Mars Exploration and Sample Return was asked by the National Aeronautics and Space Administration (NASA) to examine and report on the question of how Mars sample return missions might best be structured for effective implementation by NASA along with international partners. The committee examined alternatives ranging from scientific missions in which the United States would take a substantial lead, with international participation playing only an ancillary role, to missions in which international cooperation would be a basic part of the approach, with the international partners taking on comparably large mission responsibilities. On the basis of scientific strategies developed earlier by the Space Studies Board, the committee considered the scientific and technical basis of such collaboration and the most mutually beneficial arrangements for constructing successful cooperative missions, particularly with the USSR

Improving Quality of Care in Rheumatoid Arthritis Through Mobile Patient-Reported Outcome Measurement: Focus Group Study

Background: Patient-reported outcomes (PROs) for chronic disease management can be integrated into the routine workflow by leveraging mobile technology. Objective: The objective of our study was to describe the process of our quality improvement (QI) efforts using tablets for PRO collection in a busy, academic rheumatology practice to support a treat-to-target (TTT) approach for rheumatoid arthritis (RA) management. Methods: Our QI team designed a process for routine collection of PROs for RA patients at the Arthritis Center, employing information technology and an electronic medical record (EMR) system. Patients received a tablet at the clinic check-in desk to complete the Routine Assessment of Patient Index Data 3 (RAPID3) survey, a validated RA PRO. RAPID3 scores were uploaded to the EMR in real time and available for use in shared decision making during routine office visits. Weekly data were collected on RAPID3 completion rates and shared with front desk staff and medical assistants to drive improvement. Patients in our patient family advisory council and focus groups provided informal feedback on the process. Results: From May 1, 2017, to January 31, 2019, a total of 4233 RAPID3 surveys were completed by 1691 patients. The mean age of patients was 63 (SD 14) years; 84.00% (1420/1691) of the patients were female, and 83.00% (1403/1691) of the patients were white. The rates of RAPID3 completion increased from 14.3% (58/405) in May 2017 to 68.00% (254/376) in September 2017 and were sustained over time through January 2019. Informal feedback from patients was positive and negative, relating to the usability of the tablet and the way rheumatologists used and explained the RAPID3 data in shared decision making during the office visit. Conclusions: We designed a sustainable and reliable process for collecting PROs from patients with RA in the waiting room and integrated these data through the EMR during office visits

Fundus first laparoscopic cholecystectomy in patients with gall stone disease and the Fitz-Hugh-Curtis syndrome

Background: To present this experience using the fundus-first technique during laparoscopic cholecystectomy for the management of symptomatic gall stone disease with an intra-operative finding of Fitz-Hugh-Curtis syndrome.Methods: This is a prospective review of patients who had the fundus-first dissection during laparoscopic cholecystectomy. The study was carried out at the Jos University Teaching Hospital (JUTH), and FOMAS hospital, both of which are tertiary hospitals located in Jos. Patients were recruited from January 2017 - January 2019. All patients undergoing laparoscopic cholecystectomy who had an intraoperative diagnosis of Fitz-Hugh-Curtis syndrome, and who had the fundus-first dissection, were included in the study. Patients who had fundus-first dissection for indications other than Fitz-Hugh-Curtis syndrome, were excluded from the study. Demographic and clinical information of patients included age, sex, duration of surgery, complications, and duration of hospital stay. Descriptive statistics were applied.Results: A total of 76 patients had elective laparoscopic cholecystectomies over the study period. Of that number, 17 (22.4%) patients had an intra- operative diagnosis of Fitz-Hugh-Curtis syndrome, and had the fundus-first dissection. The mean patient age was 46.3 years (SD = 11.7 years). All patients were female. The mean operating time was 70 minutes (SD = 23 minutes). The duration of hospital stay was 24 hours. There was one conversion due to uncontrollable intraoperative bleeding.Conclusions: This study revealed that the fundus-first dissection is suitable for removing the gall bladder during laparoscopic cholecystectomy in patients with gall stone disease, and an intraoperative finding of Fitz-Hugh-Curtis syndrome

Theory of Coexistence of Superconductivity and Ferroelectricity : A Dynamical Symmetry Model

We propose and investigate a model for the coexistence of Superconductivity (SC) and Ferroelectricity (FE) based on the dynamical symmetries $su(2)$ for the pseudo-spin SC sector, $h(4)$ for the displaced oscillator FE sector, and $su(2) \otimes h(4)$ for the composite system. We assume a minimal symmetry-allowed coupling, and simplify the hamiltonian using a double mean field approximation (DMFA). A variational coherent state (VCS) trial wave-function is used for the ground state: the energy, and the relevant order parameters for SC and FE are obtained. For positive sign of the SC-FE coupling coefficient, a non-zero value of either order parameter can suppress the other (FE polarization suppresses SC and vice versa). This gives some support to "Matthias' Conjecture" [1964], that SC and FE tend to be mutually exclusive. For such a Ferroelectric Superconductor we predict: a) the SC gap $\Delta$ (and $T_c$) will increase with increasing applied pressure when pressure quenches FE as in many ferroelectrics, and b) the FE polarization will increase with increaesing magnetic field up to $H_c$. The last result is equivalent to the prediction of a new type of Magneto-Electric Effect in a coexistent SC-FE material. Some discussion will be given of the relation of these results to the cuprate superconductors.Comment: 46 page

On the question of universality in \RPn and \On Lattice Sigma Models

We argue that there is no essential violation of universality in the continuum limit of mixed \RPn and \On lattice sigma models in 2 dimensions, contrary to opposite claims in the literature.Comment: 16 pages (latex) + 3 figures (Postscript), uuencode

Tuberculin screening of some selected Fulani lactating cows in north-central Nigeria

The prevalence of mycobacterial infection among lactating Fulani cows was investigated in the Federal Capital Territory, Abuja and Kaduna State of Nigeria. Tuberculin testing using single comparative intradermal tuberculin test showed a 14.6 % positive, 4 % doubtful, and 81.4 % negative reactors. Mycobacterial infection was found to be present in the nomadic (constantly moving) and seminomadic (limited movement) management systems studied but management showed no significant effect on the prevalence of the disease. However, the prevalence was significantly higher in older age groups than the younger ones (P < 0.05).Peer reviewedSubmitted Versio

Drag in paired electron-hole layers

We investigate transresistance effects in electron-hole double layer systems with an excitonic condensate. Our theory is based on the use of a minimum dissipation premise to fix the current carried by the condensate. We find that the drag resistance jumps discontinuously at the condensation temperature and diverges as the temperature approaches zero.Comment: 12 pages, 1 Figure, .eps file attache

Prenatal ultrasound diagnosis of anterior abdominal wall defects in sub Saharan Africa; simple but often missed

Background: Congenital anterior abdominal wall defects (AAWD) is a spectrum of abdominal wall defects that includes omphalocele, gastroschisis, bladder exstrophy, cloacal exstrophy, prune belly syndrome and pentalogy of Cantrell. Early Prenatal diagnosis of AAWD provides opportunity for abnormal karyotypes screening and planned delivery in a specialized centre. Ultrasound can detect these defects during pregnancy. This study aims to evaluate the detection rate of AAWD during routine obstetric ultrasonography in our region.Methods: A retrospective study of all patients that presented with AAWD to our centre from January 2008 to July 2020. Data included patient’s age, sex, birth weight, diagnosis, resuscitation time, outcome, maternal age, parity and antenatal ultrasound scan (USS) records. Antenatal USS before 12 weeks only, were excluded. Data analysed using excel.Results: Of the 140 with AAWD, 84.29% had omphalocele, 10% gastroschisis, 2.14% prune belly syndrome and 0.71% each with bladder exstrophy, cloacal exstrophy and pentalogy of Cantrell. There were 123 booked pregnancies. Majority (112) had antenatal care elsewhere while 11 attended our Centre. Ultrasonography of 108 pregnancies scanned at12 weeks or beyond, had 4 confirmed prenatal diagnosis of AAWD. All done in our centre. Mean gestational age at diagnosis was 24weeks. Outcome was rupture1 (25%) and 25% mortality (prenatally diagnosed) and 51.92% mortality for patients with missed diagnosis.Conclusions: Our obstetric ultrasound detection rate of AAWD is very low. There is a need for improvement in training to improve perinatal care of these defects
