Vengono presentati i due articoli che seguono, relativi agli Independent Accountability Mecanisms (IAMS) delle istituzioni finanziarie internazionali. Si tratta di alcuni risultati di un Workshop tenuto nell'ambito del PRIN 2012 (2012SAM3KM) in materia di Codificazione dei procedimenti amministrativi europei, nel quale sono state discusse le potenzialità del sistema degli IAMS per le agenzie, le istituzioni e gli organismi dell'Unione Europea.
STRUTTURA E FUNZIONAMENTO DEI MECCANISMI DI RESPONSABILITÃ€ INDIPENDENTE (IAMS)
Authors: Bissell Richard E.
Published: June 2019

l'inserimento, negli anni "90, dei cosiddetti "meccanismi indipendenti di responsabilità" (IAMs) nelle organizzazioni internazionali ha diverse origini. Un lavoro seminale del 1991 della Banca Mondiale si concentrava sulla necessità di responsabilizzare i governi nei confronti dei cittadini come condizione di maggior successo dei progetti promossi dalla Banca stessa. Se la maggior parte dell'attività derivante da tali meccanismi consisteva nel rispondere a reclami concernenti servizi governativi, essa alimentava a sua volta le aspettative dei cittadini per quanto riguarda la reattività delle organizzazioni pubbliche. l'idea che un individuo che riteneva violati i propri diritti umani potesse ricorrere a un organismo internazionale costituiva una novità sostanziale. Ãˆ inoltre rilevante il fatto che le istituzioni internazionali attribuiscano valore al fatto di "aprire" le proprie operazioni così da consentire che le denunce vengano effettuate e che a esse sia data risposta. La responsabilità internazionale, dopo 25 anni di esperienza, può infine trarre vantaggio dalla modernizzazione dei sistemi: le opportunità offerte dalle nuove tecnologie, ad esempio, stanno rapidamente annullando le distanze in gran parte del mondo.
UNA NUOVA GUERRA FREDDA?
Authors: Romano Sergio
Published: June 2019

Quando visitò la Cina nel giugno del 1989 Michail Gorbaciov, segretario generale del PCUS e presidente dell'Unione Sovietica, aveva due obiettivi. Voleva rendersi conto personalmente del modo in cui le riforme di Deng Xiaoping stavano trasformando il Paese e sperava di rattoppare gli strappi politici e ideologici che avevano turbato le relazioni fra Mosca e Pechino, dal ritiro dei consulenti sovietici all'epoca di Krushev sino ai duri scontri militari sull'Ussuri nel 1968 e alla diverse posizioni assunte dai due Paesi durante la crisi afghana del 1979. Allo stesso tempo il presidente sovietico avrebbe cercato di spiegare a Deng la sua perestrojka. Le intenzioni erano ragionevoli, ma il clima cambiò quando la presenza del leader sovietico a Pechino ebbe l'effetto di entusiasmare i giovani della capitale. Mentre i dirigenti cinesi stavano gradualmente introducendo nell'economia le regole del mercato, Gorbaciov parlava di "glasnost" e sembrava deciso a cambiare quelle del sistema politico. Non appena i sovietici lasciarono Pechino per tornare in patria alcune migliaia di giovani cinesi cominciarono a darsi appuntamento in piazza Tienanmen per chiedere riforme democratiche. Da quel momento il leader sovietico smise di essere per la Cina un possibile modello e la sua caduta nel dicembre 1991 dimostrò alla dirigenza cinese che la riforma tentata da Mosca era un rischio da evitare. Credo che questo spieghi perchè la data del 3 giugno 2019 sia stata attesa da Xi Jinping, presidente della Repubblica popolare cinese, con una certa apprensione. [Continua]
Deducing the stage-discharge relationship for contracted weirs by the outflow theory of Malcherek
Authors: Ferro Vito , Aydin Ismail
Published: June 2019

The aim of this paper was the deduction of a new stage-discharge relationship for a contracted weir, having a crest length less than the channel width, by using the Malcherek’s outflow theory. The average outflow velocity over the rectangular contracted weir was expressed in terms of the head over weir, the momentum correction coefficient and the ratio between the crest length and the channel width. This theoretically deduced stage-discharge formula was calibrated by measurements carried out for values of the ratio between the crest length and the channel width ranging from 0.3125 to 0.9375. In particular, a relationship to estimate the momentum correction coefficient for contracted weirs was deduced. The analysis showed that the proposed stage-discharge relationship is characterised by an excellent performance and allows to measure discharge values characterised by errors which are, for 96.0% of the measured values, less than or equal to ±5%.

Institutional tuberculosis infection control in a rural sub-district in South Africa: A quality improvement study
Authors: Mekebeb Martha B. , Von Pressentin Klaus , Jenkins Louis S.
Published: June 2019

Background: Tuberculosis (TB) is a major global health challenge, and South Africa is one of the high-burden countries. A national TB infection control (TBIC) guideline has stipulated three areas of infection control at health facilities: work practice and administrative control, environmental control, and personal protection for health workers.Aim: The aim of this study was to identify the gaps and address the challenges in institutional TBIC.Setting: The district hospital and a primary health care clinic within the Mossel Bay sub-district in the Western Cape.Methods: According to the national TBIC draft guideline, a quality improvement cycle was used to evaluate and improve TBIC. Each facility had an existing infection and prevention control and occupational health and safety team, which were used as the audit teams.Results: A baseline assessment was followed by a set of interventions, which did not show a significant improvement in TBIC. The difference between the pre- and post-intervention TB screening rate was not statistically significant. An assessment of time interval between 101 patients presenting with TB symptoms and diagnosed with TB was 4 days at baseline and post-intervention. Most of the anticipated improvements were dependent on the health workers’ adherence to the local TBIC policies, which emerged as an unexpected finding.Conclusion: We found good managerial commitment reflected by the presence of various policies, guidelines, specific personnel and committees to deal with infection control in general. This study has created awareness about TBIC among staff and pointed out the complexity of health workers’ behaviour towards adhering to policies.
Action of Chlorzoxazone on Ca2+ Movement and Viability in Human Oral Cancer Cells
Authors: Lu Ti , Liang Wei-Zhe , Hao Lyh-Jyh , Kuo Chun-Chi , Shieh Pochuen , Chou Chiang-Ting , Jan Chung-Ren
Published: June 2019

Chlorzoxazone is a skeletal muscle relaxant. However, the effect of chlorzoxazone on intracellular Ca2+ concentrations ([Ca2+]i) in oral cancer cells is unclear. This study examined whether chlorzoxazone altered Ca2+ signaling and cell viability in OC2 human oral cancer cells. [Ca2+]iin suspended cells was measured using the fluorescent Ca2+-sensitive dye fura-2. Cell viability was examined by water-soluble tetrazolium-1 assay. Chlorzoxazone (250–1000 μM) induced [Ca2+]irises in a concentration-dependent manner. Ca2+ removal reduced the signal by approximately 50%. Mn2+ has been shown to enter cells through similar mechanisms as Ca2+ but quenches fura-2 fluorescence at all excitation wavelengths. Chlorzoxazone (1000 μM) induced Mn2+ influx, suggesting that Ca2+ entry occurred. Chlorzoxazone-induced Ca2+ entry was inhibited by 20% by inhibitors of store-operated Ca2+ channels and protein kinase C (PKC) modulators. In Ca2+-free medium, treatment with the endoplasmic reticulum Ca2+ pump inhibitor thapsigargin (TG) inhibited chlorzoxazone-evoked [Ca2+]irises by 88%. Conversely, treatment with chlorzoxazone-suppressed TG-evoked [Ca2+]irises 75%. Chlorzoxazone induced [Ca2+]irises by exclusively releasing Ca2+ from the endoplasmic reticulum. Inhibition of phospholipase C (PLC) with U73122 did not alter chlorzoxazone-induced [Ca2+]irises. PLC activity was not involved in chlorzoxazone-evoked [Ca2+]irises. Chlorzoxazone at 200–700 μM decreased cell viability, which was not reversed by pretreatment with Ca2+ chelator 1,2-bis(2-aminophenoxy)ethane-N,N,N',N'-tetraacetic acid/acetoxy methyl. In sum, in OC2 cells, chlorzoxazone induced [Ca2+]irises by evoking PLC-independent Ca2+ release from the endoplasmic reticulum and Ca2+ entry via PKC-sensitive store-operated Ca2+ entry. Chlorzoxazone also caused Ca2+-independent cell death. Since [Ca2+]irises play a triggering or modulatory role in numerous cellular phenomena, the effect of chlorzoxazone on [Ca2+]iand cell viability should be taken into account in other in vitro studies.

Authors: Nasim Bina , Al Sughaiyer Hana , Abdul Rahman Samia , B. Inamdar Rubina , Chakaki Razan , Abuhatab Suha
Published: June 2019

Background: Vitamin D deficiency is very common worldwide but highly prevalent in the Gulf region. The clinical manifestations of Vitamin D deficiency vary depending on the severity and duration of the deficiency. Effective treatment should correct the vitamin D levels and improve other metabolic markers. Objectives: We aimed to (1) compare the efficacy of Vitamin D3 and Vitamin D2 in terms of raising serum 25(OH) total Vitamin D levels, (2) evaluate the time of its attainment, and (3) demonstrate the effect of replacement with either preparation on serum markers of bone or calcium metabolism. Patients and Methods: We conducted a randomized controlled study involving 250 adults with Vitamin D deficiency or insufficiency, assigned into 1:1 ratio to receive weekly capsules of either 50,000 IU of D2 or 50,000 IU of D3 for up to 12 weeks. Serum total Vitamin D level, calcium, phosphorus, alkaline phosphatase, and parathyroid hormone (PTH) levels were measured at 0, 8, and 12 weeks. Analysis of variance and nonparametric test Kruskal–Wallis were used for the comparison of quantitative values and the Chi-square test for comparison of categorical variables. Results: After 8 weeks of treatment, the improvement in Vitamin D level was greater for patients in the D3 group (mean = 18.74, standard error [SE] = 1.08) than that for D2 group (mean = 5.88, SE = 0.65), F (1, 240) = 113.840; P < 0.0005. Similarly after 12 weeks, the improvement in Vitamin D levels was greater for those in the D3 group (mean = 20.76, SE = 1.14) than that for the D2 group (mean = 7.93, SE = 0.79), F (1, 224) = 90.78; P < 0.0005. At 12 weeks, serum calcium, phosphorus, alkaline phosphatase, and PTH levels were not significantly different between the D3 and D2 treatment groups. Conclusions: Vitamin D3 is more efficacious and faster in increasing the level of total Vitamin D than Vitamin D2. However, no significant differences were evident on calcium, phosphorus, alkaline phosphatase, or PTH levels between groups.

Toward Complementary Food Hygiene Practices among Child Caregivers in Rural Malawi
Authors: Chidziwisano Kondwani , Slekiene Jurgita , Kumwenda Save , Mosler Hans-Joachim , Morse Tracy
Published: June 2019

Despite being preventable, foodborne diseases remain a global health challenge. Poor food hygiene practices such as improper handling of kitchen utensils are among the major causes of diarrhea transmission. A formative study was conducted in Malawi to inform an intervention design to promote complementary food hygiene practices. An assessment of contextual and psychosocial factors for behavior change was conducted using Risk, Attitude, Norms, Ability, and Self-regulation model. We conducted 323 household surveys with caregivers of children aged 6 to 24 months. Analysis of variance was used to estimate difference between doers and non-doers of three targeted behaviors: washing utensils with soap, keeping utensils on a raised place, and handwashing with soap. Analysis of variance analyses revealed that literacy level, ownership of animals, and presence of handwashing facility and dish racks were contextual factors predicting storage of utensils on an elevated place and handwashing frequencies. Psychosocial factors, such as time spent to wash utensils with soap, distance to the handwashing facility, and cost for soap, had an influence on washing utensils and handwashing practices. Perceived vulnerability determined effective handwashing and storage of utensils. Perceived social norms and ability estimates were favorable for the three targeted behaviors. Promotion of already existing targeted beneficial behaviors should be encouraged among caregivers. Risk perceptions on storage of utensils and handwashing practices should be increased with motivational exercises such as paint games. Caregivers’ technical know-how of local dish rack and tippy tap construction is essential.

Revolución y mística en Gustav Landauer
Authors: D'ANGELO VALERIO
Published: June 2019

el presente artículo quiere investigar el papel de la mística en la teoría política de Gustav Landauer. La tesis que se defenderá es que la “conservación revolucionaria” que caracteriza la propuesta política landaueriana tiene que enmarcarse en una concepción mística del tiempo histórico, basada en una recuperación del pasado como instrumento de emancipación política. Para esta finalidad se analizará, en un primer párrafo, el contenido utópico a la vez que restaurador de la noción landauerianana de revolución, y, en un segundo apartado, la propuesta acerca de una nueva comunidad socialista. Finalmente, se concluirá que el “romanticismo revolucionario” que entraña la teoría política del autor, y sus continuas referencias a la vida social y política de la Edad Media, puede ser entendido sólo a la luz de un anarquismo mesiánico donde una forma sui generis de espiritualidad y la recuperación del pasado juegan un rol determinante para un auténtico proyecto revolucionario
The image of Arab/Amazigh and Moroccan Women in the Media Badia Elharraki Sidi Benabdellah University Faculty of Letters, Fez-Saiss, Fez, Morocco Tel: 212+666082246 E-mail: badiamst@hotmail.fr

AbstractThis article aims at reviewing the relevant literature on the image of Moroccan women in the media. We show that Arab women in general and Moroccan women specifically are underrepresented in media outlets. Afterwards, we focus on the category of Moroccan women subjected to violence and the way media deals with them as they constitute a fragile social category that should be studied. In this respect, we attempt to understand the root of the phenomenon of gender violence in Morocco since research in this field is rare and incomplete as the majority of the findings are to be found in general reports and human rights accounts. Among the reasons behind the vulnerability of Moroccan women subject to violence, we enumerate many including poverty and illiteracy where language is a crucial component.
Understanding Torah: Ancient Legal Text, Covenant Stipulation, and Christian Scripture
Authors: Walton John H.
Published: June 2019

When we read the “laws” of the Pentateuch, we often labor under some misperceptions. We assume that they represent legislation, a presupposition that we can correct through a careful assessment of ANE legal texts and an understanding of their literary context in the OT. We assume that they have been compiled as a coherent book whose inconsistencies therefore become problematic. We can correct this through a careful assessment of the unassailable fact that ancient Israel was a hearing-dominant culture in which we encounter scribes and documents rather than books and authors. We assume that we need to interact with Torah as rules that reflect on modern morality, even if not on salvation. Based on an understanding of the Torah in its ancient context and in its literary context, we can offer some refinement concerning how the Torah plays an important role in God’s revelation that retains its full authority today.
X-ray computerized tomography for characterization of pick-up destruction and pick-up parameter optimization of tomato root lumps
Authors: Mao Hanping , Liu Yang , Han Luhua , Sheng Baoguo , Ma Guoxin , Li Yaxiong
Published: June 2019

This study was aimed to find the causes of pick-up destruction of tomato root lumps using X-ray microcomputed tomography, and to identify the pick-up parameters of low root lump destruction. The roots and pores were reconstructed three-dimensionally and analyzed quantitatively. It was found that the roots acted winding and wraping the root lumps and thus preventing the substrate from loosening. The major causes for root lump destruction were pore aggregation and crack formation. The apex and circumference of pick-up pins were areas where root lumps were prone to fracture and breakage, respectively. Lacunarities of these two areas were used as index to quantify the root lump destruction. Single-factor analysis of variance was conducted with pick-up pin shape (circular, flat), diameter (2, 2.5, 3 mm) and initial pick-up angle (18°, 21°, 24°) as the test factors and then the effects of these three factors on root lump destruction were studied. It was found the lacunarities at the fracturable area and breakable area both increased with the rise of pick-up pin diameter and decreased with the rise of initial pick-up angle. At the same pick-up conditions, lacunarities with the use of flat pins always surpassed that of circular pins. When circular pick-up pins with diameter of 2 mm and initial pick-up angle of 24° were used, the destruction rate of root lumps (6.63%) was smaller than under other test conditions. The optimized pick-up parameters can be used to guide gripper design and to improve the working performance of automatic transplanters.

Published: June 2019

Objective: Evaluate the relation of nursing workload, evaluated by the Nursing Activities Score (NAS), with the occurrence of Ventilator-associated Pneumonia (VAP) in an Intensive Care Unit (ICU) and the impact of VAP on hospitalization costs.Methods: Retrospective cohort study in Adult ICU of a high complexity Brazilian university hospital. The profile, outcomes, costs, and daily NAS from patients were collected. We also proposed some workload indicators based on NAS daily evaluation.Results: The study included 195 patients, 27.17% diagnosed with VAP. VAP was more prevalent in patients diagnosed with trauma on admission. The total costs of care were higher for VAP patients. In all multivariate models tested were predictive for VAP: the patient's intubation that occurs in days prior of the ICU admission day (higher risk if occurs in days prior the ICU admission day) and ventilation time prior ICU (higher risk if higher time). We found others predictors, but these were dependent on the model tested. Additional risk predictors were tracheostomy, propofol use, neuromuscular blocker use and the higher NAS from admission. The protective factors found were the percentage of adequacy of the assignment based in NAS that measure if the workload measured by the NAS was offered and the increment in NAS during the ventilation time.Conclusions: The offering of an adequate nursing work scale (adequate number of professionals for the care), as a function of the nursing workload measured by the NAS, could be effective in the reduction of VAP, hospital stay time and hospital costs.

The aim of this article is to assess the determinants of industrial manufacturing in the CEMAC zone. To achieve this, we make use of a gravity model on a static panel with random effects, according to the methodology proposed by Hausman-Taylor. The results show that the population, value added of the manufacturing sector, colonial links and geographic proximity have significant impacts with the expected signs. On the other hand, the difference in absolute value of per capita GDP, the business climate, financial inflows as well as actual distance are the group variables that arise as constraints to export manufacturing.
Government Sectoral Expenditure and Poverty Alleviation in Nigeria
Authors: Omodero Cordelia Onyinyechi
Published: June 2019

Poverty alleviation in the developing countries has been an issue of concern especially in Africa which accounts for two-thirds of the total number of people in the world living in extreme poverty. The World Poverty Clock indicates that half of Nigerian population are dwelling in abject poverty, implying that MDGs agenda seems to be ineffective in Nigeria which is the giant of Africa. Thus, this study examines the role of government sectoral expenditure on poverty alleviation using a secondary form of data covering a millennium period from 2000 to 2017. The study employs ordinary least squares technique and the regression result indicates that government expenditure on agriculture, building and construction, education and health do not have any significant impact on poverty alleviation in Nigeria. The study therefore concludes that government spending on these key sectors of the economy is insufficient and recommends that more funds should be budgeted to boost these sectors in order to eradicate the scourge of poverty in the country.

Published: June 2019

Magneto-Electro-Thermo nanobeam resting on a nonlinear elastic foundation is presented. This beam is subjected to the external electric voltage and magnetic potential, mechanical potential and temperature change. Also, we added the new material PTZ-5H-COFe2O4. The governing equations and boundary conditions are derived using Hamilton principle. These equations are discretized by using three differential quadrature methods and iterative quadrature technique to determine the natural frequencies and mode shapes. Numerical analysis is introduced to explain the influence of computational characteristics of the proposed schemes on convergence, accuracy and efficiency of the obtained results. The obtained results agreed with the previous analytical and numerical ones. A detailed parametric study is conducted to investigate the influences of different boundary conditions, various composite materials, nonlinear elastic foundation, nonlocal parameter, the length-to-thickness ratio, external electric and magnetic potentials, axial forces, temperature and their effects on the vibration characteristics of Magneto-Electro-Thermo-Elastic nanobeam.

Published: June 2019

Este trabalho aplicou o indicador Overall Equipment Effectiveness (OEE) e as ferramentas da qualidade no processo de destilação de uma indústria de biotecnologia situada no Norte Fluminense, a fim de identificar a eficiência do equipamento mais crítico do processo, apontar a causa raiz da falha de maior impacto e propor estratégias de melhoria. Os instrumentos utilizados para o alcance da pesquisa foram 5S, fluxograma, gráfico de Pareto, diagrama de causa e efeito, brainstorming, 5W1H e o software Microsoft Office Excel como suporte para a organização e análises dos dados. A metodologia tradicional para calcular o OEE careceu de adaptações, pois outras variáveis precisaram ser contabilizadas para mensurar de forma eficiente o equipamento e que fosse condizente com a realidade da empresa. Os resultados apontaram que o equipamento estava abaixo da classe mundial, cujo valor de corte é 85%, e que a falha de maior impacto foi parada por obstruções, ocasionada pela baixa frequência na limpeza química. A pesquisa concluiu que a metodologia adaptada foi eficiente para identificar as perdas do processo, mensurar a real utilização do equipamento e aplicar ações de melhorias.
Rare proliferative and inflammatory pathologies localized in the temporal bone - a review of the literature
Authors: Roszkowski Adam Roszkowski , Witkowska Alicja , Baranek Piotr , Rzepakowska Anna , Wnuk Emilia , Niemczyk Kazimierz
Published: June 2019

Proliferative-inflammatory pathologies may occupy the temporal bone, resulting in: hearing loss, vestibular dysfunction, and neuropathies from cranial nerve compression. Although their occurrence is episodic, the appropriate diagnostic procedure is extremely important to achieve expected therapeutic effect.
The aim of study was characterization of selected proliferative-inflammatory pathologies that may occupy the temporal bone: fibrous dysplasia, inflammatory pseudotumor, osteoradionecrosis, and presentation of diagnostic methods for the differentiation of these diseases as well as discussion on appropriate therapeutic options.
Fibrous dysplasia (fibrous dysplasia) is a slowly progressive, benign bone disorder of unknown etiology characterized by abnormal proliferation of fibrous tissue.
IPT (inflammatory pseudotumor) is a rare, non-malignant inflammatory process of unknown etiology, characterized by connective tissue proliferation and infiltration of inflammatory cells.
Osteoradionecrosis of the temporal bone (TB-ORN) is a rare but potentially fatal complication of radiotherapy for head and neck cancer.
Due to the similarity of symptoms with typical inflammatory conditions of middle ear (pain, otorrhea, hearing loss), selected disorders may be a dilemma regarding the diagnosis and proper further treatment. The clinical examination is mandatory, however radiological imaging may demonstrate the existence of specific changes and direct the diagnosis. The computed tomography of fibrous dysplasia shows the abnormal organization of the bone structure. Magnetic resonance, as the most sensitive for inflammatory pseudotumors, visualizes inflammatory infiltrates in soft tissues. The spiral tomography of temporal identifies the erosion in the course of osteoradionecrosis. However the final diagnosis may be establish post the histopathological examination and exclusion of the neoplastic process.

Malicious applications are widespread for Android despite the taken serious actions by the operating system. Static and dynamic analysis techniques are utilized to detect malware by identifying the signatures of malicious applications by inspecting both the resources and behaviors of malware, respectively. In this study, what static analysis can utmost offer to detect malware in Android ecosystem is discussed and experimented on commonly used datasets in the literature by proposing a novel Android malware detection approach based on static analysis techniques. Some novel static analysis features which are proved to be effective in terms of detecting malware in Android ecosystem and are underestimated by the related work in the literature are introduced by proving their effectiveness in this study. The experimental result shows that the proposed Android malware detection approach is very effective in terms of detecting Android malware. Each feature used by the proposed approach is evaluated by using different types of machine learning techniques in order to highlight its impact on detecting malware and inform the digital investigators. The accuracy of the proposed static analysis approach is calculated as high as 0.987 for 10,865 applications.

Simulink and its state machine design toolbox Stateflow are widely-used industrial tools for the development of complex embedded systems. Due to the strongly differing execution semantics of Simulink and Stateflow, the analysis of combined models poses a difficult challenge. In this paper, we present a novel approach to relate the semantics of both the dynamic and the controller components and use it to perform an information flow analysis on a combined model consisting of discrete Simulink components and Stateflow controllers. The key idea of our approach is that we analyze the information flow in a given model by computing an over-approximation of the control flow, and deduce whether all control flow conditions combined permit information to flow on a given path or not. Our control flow analysis approach is threefold: (1) we identify timed path conditions which capture the conditions for time-dependent information flow on paths of interest for (discrete) Simulink components, and translate them into a UPPAAL timed automata representation, (2) we translate the Stateflow components to UPPAAL timed automata, and (3) we perform model checking on the resulting set of automata to analyze the existence of paths in the combined model. With our approach, we safely rule out the existence of information flow on specific paths through a model, which enables us to reason about non-interference between model parts and the compliance with security policies. Furthermore, our approach presents a starting point to generate feasible, efficient test cases and to perform compositional verification. We demonstrate the applicability of our approach using two versions of a complex case study from the automotive domain consisting of multiple safety-critical components communicating over a shared bus system.

It is challenging to recover the required compressed CT (Computed Tomography, CT) image, which is got by transferred through the internet or is stored in a signal library after being compressed. We present a recovery method for compressed sensing CT images. At present, minimizing 0-norm, 1-norm and p-norm is used to recover compressed sensing signals. However, sometimes 0-norm is an NP problem, 1-norm has no solution in theory and p-norm is not a convex function. We introduce a recovery method of compressed sensing signal based on regularized smooth convex optimization. In order to avoid solving the non-convex optimization problems and no solution condition, a convex function is designed as the objective function of optimization to fit 0-norm of signal and a fast iterative shrinkage-thresholding algorithm is proposed to find solution with the convergence speed is quadratic convergence. Experimental results show that our method has a sound recovery effect and is well suitable for processing big data of compressed CT images.
Wie zuverlässig ist das Peer-Review-Verfahren? Eine Untersuchung der Interrater-Reliabilität von Gutachter*innen auf DGPuK-Tagungen

Bevor wissenschaftliche Beiträge in Fachzeitschriften publiziert oder auf Tagungen präsentiert werden, überprüfen Herausgeber*innen bzw. Organisator*innen die Qualität der Einreichungen. Dies geschieht zumeist im Peer-Review-Verfahren, bei dem unabhängige Kolleg*innen aus dem gleichen Forschungsgebiet die Einreichung begutachten. Die vorliegende Studie hinterfragt, wie zuverlässig das Review-Verfahren ist. Dazu untersuchen wir die Bewertungen der Einreichungen von DGPuK-Jahrestagungen und der Tagungen der fünf größten Fachgruppen über einen Zeitraum von fünf Jahren. Basierend auf 3537 Reviews von 23 Tagungen analysieren wir Interrater-Reliabilitäten (Krippendorffs á und Brennan und Predigers ê) und Spannweiten über verschiedene Einzelkriterien (Passung, Originalität, Relevanz, Theorie, Methode und Darstellung) und Gesamturteile; zudem fokussieren wir Ursachen von Dissens bzw. Konsens. Die Studie zeigt, dass unter Gutachter*innen durchaus Uneinigkeit besteht: Dies betrifft sowohl die Gesamtwertung als auch alle Einzelwertungskategorien. Die Bildung von Durchschnitten über mehrere Kriterien hinweg erhöht jedoch die Übereinstimmung der Urteile. Abschließend diskutieren wir Ideen, um Begutachtungsverfahren zukünftig zu verbessern.

We consider thermochemical mantle plumes with thermal power 1.6·1010 W<N<2.7·1010 W (relative thermal power 1.15<Ka<1.9) as plumes with an intermediate thermal power. Such plumes are formed at the core–mantle boundary beneath cratons in the absence of horizontal free‐convection mantle flows beneath them, or in the presence of weak horizontal mantle flows. A proposed scheme of convection flows in the conduit of a plume with an intermediate thermal power is based on laboratory and theoretical modeling data. A plume ascends (melts out) from the coremantle boundary to critical depth xкр from which magma erupts on the Earth’s surface. The magmatic melt erupts from the plume conduit onto the surface through the eruption conduit. The latter forms under the effect of superlithostatic pressure on the plume roof. While the thickness of the block above the plume roof decreases to a critical value xкр, the shear stress on its cylindrical surface reaches a critical value (strength limit) τкр.Rock fails in the vicinity of the cylindrical block and, as a consequence, the eruption conduit is formed. We estimate the height of the eruption conduit and the time for the plume to ascent to the critical depth xкр. The volume of erupted melt is estimated for kinematic viscosity of melt =0.5–2 м2/с. The depth Δx from which the melt is transported to the surface is determined. Using the eruption volume, we obtain a relationship between the depth Δx and the plume conduit diameter for the above‐mentioned kinematic viscosities. In the case that the depth Δx is larger than 150 km, the melt from the plume conduit can transport diamonds to the Earth’s surface. Thus, the plumes with an intermediate thermal power are diamondiferous. The melt flow structure at the plume conduit/eruption conduit interface is determined on the basis of the laboratory modeling data. The photographs of the simulated flow were obtained. The flow line velocities were measured in the main cylindrical conduit (plume conduit) and at the main conduit/eruption conduit interface. A stagnant area is detected in the 'conduit wall/plume roof’ interface zone. The melt flow in the eruption conduit was analyzed as a turbulent flow in the straight cylindrical conduit with diameter dк. According to the experimental modeling and theoretical data, the superlithostatic pressure in the plume conduit is the sum of the frictional pressure drop and the increasing dynamic pressure in the eruption conduit. A relationship between the melt flow velocity in the eruption conduit and superlithostatic pressure has been derived.
ZIRCON IN HIGH‐MG DIORITE OF THE CHELYABINSK MASSIF (SOUTH URALS): MORPHOLOGY, GEOCHEMICAL SIGNATURE, AND PETROGENESIS IMPLICATIONS

The article is focused on the morphology, trace element composition, U‐Pb and Lu‐Hf systems in zircon in high‐Mg diorite of the Chelyabinsk granitoid massif. Our analytical studies of the U‐Pb and Lu‐Hf isotope systems and the trace element composition were performed using mass spectrometry (MS) with inductively coupled plasma (ICP) and laser ablation (LA) of samples. It is established that the zircon formed at the last stages of crystallization of the basic melt under subsolidus conditions at low (600–700 °C) temperatures, which distinguishes it from the zircon of most other high‐Mg rocks of the intermediate composition. The internal structure of the zircon and the concentration of trace elements are locally altered under the influence of a fluid, which led to a partial disruption of the U‐Pb and Lu‐Hf isotopic systems. For the least altered areas in the zircon crystals, the age of crystallization of the parent high‐Mg melt is 362±2 Ma, which coincides with the age estimated from the geological data. Considering the isotope composition of Hf in the zircon and the trace element concentrations, there are grounds to relate the formation of high‐Mg diorite in the Chelyabinsk granitoid massif with a mixed mantle‐crustal source.
PREDICTION OF COMPRESSION AND EXTENSION ZONES IN GEOLOGICAL STRUCTURES BASED ONLY ON THE VELOCITIES OF LONGITUDINAL WAVES IN THE GEOLOGICAL MEDIUM

The article presents accurate solutions for the problem for two elastic half‐spaces with an arbitrary curvilinear interface. Our study shows that dilatation solutions (Poisson integrals) are dependent on neither an overall compression modulus nor the Poisson ratio, and depend only on the velocity of longitudinal waves. These specific solutions can be supplemented by general solutions for an incompressible elastic medium, and the boundary conditions of the rigid contact for the sum of the solutions can thus be satisfied. Relatively simple calculations make it possible to determine the divergence of the displacement field and reduce the entire problem solving process to a study of Poisson equations with a known divergence. Furthermore, predictions of volumetric compression or extension are important for geological investigations, since the zones characterized by reduced pressure rates may act as fluid attractors.
