"Influence of the Droplet Velocity on the Attenuation of Overpressures in a Water Mist." IOP Conference Series: Earth and Environmental Science 906, no. 1 (November 1, 2021): 012042. http://dx.doi.org/10.1088/1755-1315/906/1/012042.
Abstract:
Abstract Mist generator is a basic element of systems designed to protect from explosions. It is responsible for forming a suppression barrier between the place of explosion and the zone to be protected. The effectiveness of the system is determined by the capacity of the mist to suppress blast overpressure and impulse. The attenuation capacity, on its turn, depends on mist properties, such as droplet size, water concentration in mist and droplet velocity. The paper examines droplet velocity influence on overpressure and impulse attenuation in mist when the properties of the latter are in the following ranges: droplet size - 15-345 μm; droplet velocity - 5.5-35 m/s; shock wave velocity – 515-718 m/s, droplet impact angle - 900. The influence of drop velocity on blast attenuation has been assessed according to overpressure and impulse reduction factors.

Abstract:
Background and aim. In spite of numerous interventions, the control of mineral disturbances remains poor in end-stage renal failure (ESRF) patients. Chronic kidney disease - mineral and bone disorders (CKD-MBD) represent an important cause of mortality and morbidity. The aim of this study is to analyze the relationship between mineral and bone disorders (MBD) and their components impact on all-cause mortality and cardiovascular (CDV) mortality and morbidity in chronic dialysis patients. Methods. This prospective study was carried out in a cohort of 92 randomly selected patients with ESRF treated with hemodialysis (HD) and peritoneal dialysis (PD). The data regarding demographic and clinical characteristics were recorded, including vascular disease (coronary, cerebral, peripheral). The follow-up lasted 40 months and the final evaluation included the number and causes of deaths, CDV events and disease. Serum Ca, P, ALP, iPTH, albumin, cholesterol, urea and creatinine levels were measured. The plain radiographic films of hands and pelvis evaluated all bone abnormalities suggestive of renal osteodystrophy (ROD) and peripheral vascular calcification (VC). Results. All-cause annual mortality represented 9.25% in HD and 9.09% in PD patients. The CDV mortality represented almost 44% in HD patients and 66% in PD patients from all deaths. There was a high prevalence of CDV diseases and events. High and low serum P levels were associated with a worse survival rate. Hypercalcaemia was associated with high risk for CDV events in HD patients. In PD patients, the relationship between increased ALP levels and all-cause mortality was significant. Other mineral markers were not predictive of the outcome in the studied patients. In the HD patients the severity of VC was associated with all-cause and CDV mortality, and with CDV events. Male gender, hypercholesterolemia, decreased URR, albumin and creatinine were identified as risk factors for all-cause mortality. The diabetics had higher death rates. Low dialysis efficacy represented a risk factor for mortality and CDV diseases and events. In PD patients, low albumin induced a higher death rate. In PD patients the death rate was similar to HD patients. Conclusion. All-cause mortality was higher than in general population, but lower than the chronic dialysis patients’ mortality reported in other studies. The death rates in HD and PD patients were similar. VC and serum P levels influenced the outcome in the HD patients – increased the risk for all-cause and CDV mortality, but also for CDV events. ALP levels influenced outcome in PD patients. There were no significant differences between HD and PD patients regarding outcome.

Abstract:
Abstract This article aims to highlight the importance trough space and time of the canonical legislation promoted by saint Caesarius, bishop of Arles, in Provence. It starts at the council of Agde, in 506, not convened by Caesarius but presided by him. The influence of that council should not be limited, as it is usual, to the five councils he directly gathered: Arles IV (524), Carpentras (527), Orange II (529), Vaison II (529) and Marseille (533). The first national council in the franc kingdom, Orléans I (511), as well as the first national council in the burgundian kingdom, Epaone (517), are largely tributaries of Agde. Moreover, the author comments more than 300 norms taken by something like 54 other councils, till the council of Trosly (909), which shows a clear filiation from Agde.

RESUMO: O objetivo deste trabalho foi avaliar a demanda energética requerida por uma semeadora-adubadora para plantio direto, com diferentes configurações de sulcadores na implantação da cultura da soja, em áreas de várzea. O experimento foi conduzido em duas áreas agrícolas, tipicamente cultivadas com arroz irrigado, localizadas na região Central do estado do Rio Grande do Sul. Utilizou-se o delineamento de blocos aleatorizados, em arranjo bifatorial, sendo avaliadas quatro configurações de sulcadores (haste sulcadora, haste sulcadora com sistema tapa-sulco, disco ondulado e disco duplo), em duas áreas de características distintas (área agrícola 1 e área agrícola 2). As variáveis estudadas foram: força na barra de tração, velocidade real de trabalho, patinamento das rodas motrizes do trator e consumo específico de combustível. Com base nas análises dos resultados obtidos neste estudo pode-se afirmar que, os mecanismos sulcadores influenciam na demanda energética do conjunto mecanizado, independentemente da área agrícola. O consumo específico de combustível com o uso de hastes sulcadoras quando comparado aos discos foi 0,7 vezes menor, para ambas as áreas. Palavras-chave: mecanização agrícola, força de tração, consumo de combustível, eficiência. ENERGY DEMAND OF IN SOYBEAN SOWING WITH DIFFERENT FURROWER CONFIGURATIONS ABSTRACT: This research aimed to evaluate the energy demand required by a seeder-fertilizer for direct planting, with different configurations of furrowers in the implantation of soybean culture, in lowland areas. The experiment was conducted in two agricultural areas, typically cultivated with irrigated rice, located in the central region of the state of Rio Grande do Sul. A randomized block design was used, in a bifactorial arrangement, and four furrow configurations (shank, shank with furrow-groove system, corrugated disc and double disc) were evaluated in two areas with different characteristics (agricultural area 1 and agricultural area 2). The variables studied were drawbar pull, real travel speed, the slippage of the driving wheels of the tractor and specific fuel consumption. Based on the analysis of the results obtained in this study, it can be said that the furrow mechanisms influence the energy demand of the mechanized set, regardless of the agricultural area. Specific fuel consumption with the use of shanks instead of disks was 0.7 times lower, for both areas. Keywords: Agricultural mechanization, drawbar pull, fuel consumption, efficiency

Journal of Clinical Oncology 35, no. 6_suppl (February 20, 2017): 515. http://dx.doi.org/10.1200/jco.2017.35.6_suppl.515.
Abstract:
515 Background: Survival outcomes are heterogeneous across different subsets of mRCC pts. Poor risk pts have grim outcomes and are less likely to be enrolled in clinical trials, hence the lack of prospective data characterizing this pt population. We provide a comprehensive analysis of poor risk pts, as defined by three widely used prognostic models, in the era of targeted therapy. Methods: We conducted a pooled retrospective analysis of 4,736 mRCC pts treated on phase II and III clinical trials. Pts were defined as poor risk according to the Memorial Sloan Kettering Cancer Center (MSKCC), International Metastatic Database Consortium (IMDC), and Hudes prognostic risk models. We evaluated overall survival (OS), progression-free survival (PFS), objective response rate (ORR), and adverse events (AEs) in poor risk pts in each of the risk models in the total cohort and in a subset of pts who remained on treatment for >12 months (mos). The models’ concordance (c-) index was used to assess their prognostic performance. Results: We identified 1145 (24.2%), 904 (19.1%), and 1901 (40.1%) poor risk pts by IMDC, MSKCC, and Hudes models, respectively. The majority were <65 years of age (70-73%) with clear-cell histology (85-88%), prior nephrectomy (62-66%), and no prior systemic therapy (80-86%). The efficacy and toxicity outcomes as well as the c-indexes for each of the models are reported in the table below. Additionally, 9-14% of poor risk pts remained on therapy for >12 mos and had higher OS (29.8-35.2 mos) and ORR (42-53%). Conclusions: In this large database of poor risk mRCC pts, we highlight that the models have similar predictive accuracy in the targeted therapy era. We also demonstrate that poor risk pts continue to have dismal outcomes and should be considered for trials of novel agents and combinations. A subset of these pts appears to derive prolonged clinical benefit and should be further explored.[Table: see text]

Abstract:
Abstract Seventeen ceramics samples (515±95 BP, about 580 years old) and two clay raw materials from Zamala (Far-northern, Cameroon) were characterized by X-ray diffraction (XRD), thermal analysis (DTA/TG) and X-ray fluorescence spectroscopy. The aim of the work was the deduction of the production technology and provenance of these ceramics. With the exception of one sample the analysed ceramics formed a homogeneous chemical and mineralogical group. The observed mineralogical phases were quartz, mica (biotite), potassium feldspar (microcline) and plagioclase (albite and oligoclase). The XRD study of two local clays yielded the presence of quartz, kaolinite, mica, feldspar and plagioclase. The presence of the broad endothermic peak in the DTA/TG curves of the clays and its absence in the curves of the ceramics indicated that the firing temperature of the ceramics was above 550-600 °C, which is the temperature of the kaolinite-metakaolinite transformation. The firing experiments of the clay between 400-1200 °C in oxidizing atmosphere showed that mica disappeared above 900 °C. Therefore, the firing temperature of the sherds should have been between 600-900 °C. The chemical correlation between ceramics and local clay materials pointed out to a local production of these ceramics.

"Dopamine reduces aldosterone and 18-hydroxycorticosterone response to angiotensin II in patients with essential low-renin hypertension and idiopathic hyperaldosteronism." Clinical Science 68, no. 3 (March 1, 1985): 291–99. http://dx.doi.org/10.1042/cs0680291.
Abstract:
1. Plasma aldosterone, 18-hydroxycorticosterone (18-OH-B), 18-hydroxydeoxycorticosterone (18-OH-DOC), corticosterone, cortisol and prolactin levels were determined during an angiotensin II infusion at increasing rates both with and without a simultaneous infusion of dopamine in seven normotensive subjects, in ten patients with essential hypertension, and in ten patients with primary aldosteronism. In a second set of experiments, maximum increases of these plasma levels were determined after metoclopramide (10 mg intravenously) in all subgroups. 2. As compared with the other groups, an exaggerated angiotensin II-induced response of plasma aldosterone and 18-OH-B levels was observed in the five patients with low-renin essential hypertension (LREH) and in five patients with idiopathic hyperaldosteronism (IHA). 3. Dopamine reduced the maximal increase of aldosterone and of 18-OH-B after angiotensin II to 259 ± 48 (sem) pg/ml and 511 ± 152 pg/ml repectively in LREH (without dopamine: 515 ± 74 and 908 ± 201 respectively; P<0.05), and to 466 ± 197 and 741 ± 212 in IHA (without dopamine: 766 ± 193 and 1264 ± 337 respectively; P<0.05). 4. The maximal increases of plasma aldosterone, 18-OH-B, and prolactin after metoclopramide (10 mg intravenously) were higher (P<0.01) in patients with LREH and in patients with primary aldosteronism. Plasma levels of 18-OH-DOC, corticosterone and cortisol were not affected by the stimuli applied. 5. The exaggerated response to metoclopramide as well as to angiotensin II and its reversion only by pharmacological doses of dopamine are consistent with an increased but ineffective dopamine inhibition of aldosterone and 18-OH-B in LREH and IHA.

Abstract:
Palaeochannel development along the middle reaches of the River Irthing valley floor, Cumbria, UK, has been reconstructed via a range of palaeoenvironmental techniques. This has enabled the analysis of interactions between the geomorphological, hydrological and ecological components of the floodplain system during the mid to late Holocene. Geornorphological mapping, surveying and lithostratigraphic analysis of palaeochannel fills along a 2.5 kilometre reach of the valley floor has determined the character of Holocene channel and floodplain evolution and the physical context for palaeochannel habitat development. Chronological controls have been provided by historical map analysis and radiocarbon dating. The River Irthing valley floor experienced net fluvial incision from the Pleistocene-Holocene boundary up until the mid Holocene, while late Holocene floodplain evolution has been characterised by a series of channel avulsion and limited floodplain reworking. Periods of channel incision and planform change have been dated to 2440-1920 cal. BC, 670-970 cal. AD, 1410-1620 cal. AD and the late eighteenth to early nineteenth century AD. Five palaeochannel reaches with well-preserved organic rich channel fill sediments were selected for detailed lithostratigraphic analyses (by multiple core transects) and plant macrofossil analyses. Channel fills provide evidence of rapid biotic response to channel abandonment and subsequent changes to the physical characteristics and trophic status of the habitat. Hydroseral sequences from aquatic to wetland to floodplain woodland communities and the affects of human activity on palaeochannel development are also evident. The results indicate high magnitude flood inundation significantly affects vegetation succession and highlight the importance of physical processes and the landscape context in determining the characteristics of palaeochannel development. The research emphasises the application of plant macrofossil analysis to organic rich alluvial sediments.

Tian, Na. "Novel optimisation methods for numerical inverse problems." Thesis, University of Greenwich, 2011. http://gala.gre.ac.uk/9099/.
Abstract:
Inverse problems involve the determination of one or more unknown quantities usually appearing in the mathematical formulation of a physical problem. These unknown quantities may be boundary heat flux, various source terms, thermal and material properties, boundary shape and size. Solving inverse problems requires additional information through in-situ data measurements of the field variables of the physical problems. These problems are also ill-posed because the solution itself is sensitive to random errors in the measured input data. Regularisation techniques are usually used in order to deal with the instability of the solution. In the past decades, many methods based on the nonlinear least squares model, both deterministic (CGM) and stochastic (GA, PSO), have been investigated for numerical inverse problems. The goal of this thesis is to examine and explore new techniques for numerical inverse problems. The background theory of population-based heuristic algorithm known as quantum-behaved particle swarm optimisation (QPSO) is re-visited and examined. To enhance the global search ability of QPSO for complex multi-modal problems, several modifications to QPSO are proposed. These include perturbation operation, Gaussian mutation and ring topology model. Several parameter selection methods for these algorithms are proposed. Benchmark functions were used to test the performance of the modified algorithms. To address the high computational cost of complex engineering optimisation problems, two parallel models of the QPSO (master-slave, static subpopulation) were developed for different distributed systems. A hybrid method, which makes use of deterministic (CGM) and stochastic (QPSO) methods, is proposed to improve the estimated solution and the performance of the algorithms for solving the inverse problems. Finally, the proposed methods are used to solve typical problems as appeared in many research papers. The numerical results demonstrate the feasibility and efficiency of QPSO and the global search ability and stability of the modified versions of QPSO. Two novel methods of providing initial guess to CGM with approximated data from QPSO are also proposed for use in the hybrid method and were applied to estimate heat fluxes and boundary shapes. The simultaneous estimation of temperature dependent thermal conductivity and heat capacity was addressed by using QPSO with Gaussian mutation. This combination provides a stable algorithm even with noisy measurements. Comparison of the performance between different methods for solving inverse problems is also presented in this thesis.

Abstract:
Davant l'augment de l'ús de reconstruccions virtuals als museus arqueològics, aparentment sense una veritable reflexió teòrica (museològica i epistemològica) que les recolzi, aquesta tesi pretén esbrinar la utilitat de la Realitat Virtual com a instrument de presentació de l'Arqueologia i per quins motius, i alhora proposar unes bases teòriques per aquest ús, a partir de la construcció d'un marc teòric i metodològic semiòtic.La tesi s'estructura en tres volums. En el primer es presenta un panorama general del projecte (objectius, metodologia, contribució a l'estat de la qüestió, perspectives de futur) i també les concepcions bàsiques sobre l'Arqueologia (situació epistemològica i funció social), els museus (paper dels objectes, funció social dels museus, funció comunicativa i educativa de l'exposició, primeres paraules sobre l'ús de les TIC als museus) i la Realitat Virtual (a partir de sis vectors d'aproximació a la complexitat del concepte) que han guiat el procés d'investigació. En el segon volum es tracta pròpiament la qüestió de partida i s'intenta esbrinar (a través de la cerca bibliogràfica sobre cada element, la seva aplicació a la RV i la verificació a partir d'avaluacions empíriques publicades) si la Realitat Virtual és útil com a eina de comunicació des de totes les perspectives implicades (percepció, cognició, semiòtica de les imatges/del llenguatge, epistemologia arqueològica, museologia, museografia i aprenentatge), reunides en tres nivells analítics: sintaxi, semàntica i pragmàtica. El tercer volum conté un resum de tota la tesi i les conclusions del procés de recerca, que corresponen als fonaments teòrics sobre l'ús de la RV als museus arqueològics des del punt de vista de la recerca i de la museologia.
El present treball no és únic, sinó que ja hi ha hagut altres projectes orientats a la comprensió de la utilitat comunicativa de la RV ja des del moment que les recerques van sortir de i l'àmbit militar i per això es pot situar com a continuador d'aquestes. Però ara aporta algunes novetats, entre les quals cal destacar la construcció d'un marc teòric i metodològic, la Semiòtica, que comporta els següents avantatges: permet aplicar i adaptar la metodologia analítica desenvolupada en altres àmbits; integrar en un discurs coherent les recerques sobre els avantatges i inconvenients de la RV des dels diferents àmbits implicats; obtenir una eina avaluativa per contrastar en el futur aquesta fonamentació teòrica; i, finalment, com a conseqüència pràctica del marc teòric, proporcionar una base racional i explícita per a l'ús científic i divulgatiu de la RV en Arqueologia.
Given the spread of the use of virtual reconstructions in archaeological museums, apparently without a true theoretical consideration (museological and epistemological) to support them, the aim of this thesis is to find out whether and how Virtual Reality is useful for the presentation of Archaeology in museums and at the same time to propose a theoretical bases for this use, through the establishment of a semiotica theoretical and methodological framework.
The thesis is structured in three volumes. The first one presents a general overview of the project (goals, methodology, contribution to the state of the art, future perspectives) and also the basic concepts about Archaeology (epistemological situation and social function), museums (role of objects, museums' social function, communicational and educational role of the exhibition, first words about the use of ICT in museums) and Virtual Reality (using six vectors of approximation to the complexity of the concept) that guided the research process. The second volume is devoted to the starting question and tries to find out (through a bibliographical search about each element, its application to VR and its verification through published empirical evaluations) if VR is useful as a communication tool from all the perspectives involved (perception, cognition, semiotics of images/language, archaeological epistemology, museology, museography and learning), distributed in three analytical levels: syntax, semantics and pragmatics. The third volume contains a summary of the thesis and the conclusions of the research project, which correspond to the theoretical foundations of the use of VR in archaeological museums from the research and the museological perspective.
The present research project is not unique and can be considered a continuation of early research into the usefulness of VR for learning performed outside the military field. However, it does introduce new elements, amongst which we should highlight the construction of a theoretical and methodological framework, semiotics, which encompasses the following advantages: to apply and adapt the powerful analytical methodology coming from semiotics as well as other fields; to integrate in a coherent discourse research into the advantages and disadvantages of VR from the different fields involved; to obtain an evaluative tool for future verification of these theoretical foundations; and finally, as the practical consequence of the theoretical framework, it provides a rational and explicit basis for the scientific and disseminative use of VR in Archaeology.

Abstract:
Doppler-SODAR measurements are commonly used to derive the vertical wind profile. One main advantage of the Mini-SODAR (from the company Remtech) is its small size and weight and therefore it is easy to handle and set up in short time. Two long-term measurements were operated in September and October 2009. A statistical comparison was made between the Mini-SODAR, the tower and the DWD-SODAR (from the company METEK) for the two measurement periods. It is presented here that the Mini-SODAR overestimates the tower measurements and also the
measurements of the DWD-SODAR. It is also shown, that the Mini-SODAR is able to determine the mean flow conditions in the lower boundary layer (up to 200 m).

Renton, Dave. "The attempted revival of British fascism : fascism and anti-fascism, 1945-51." Thesis, University of Sheffield, 1999. http://etheses.whiterose.ac.uk/14777/.
Abstract:
The thesis is divided into six sections. The Introduction discusses the themes of the dissertation, notably fascism, anti-fascism and Britain in the 1940s. It reviews the existing literature and outlines the method used. The first chapter examines the legacy of the inter-war years and the impact of internment on the fascists. It analyses the British League of Ex-Servicemen and Women and the Mosley book clubs, which came together to form the Union Movement. The chapter ends in 1951 with Oswald Mosley's decision to leave Britain, a symbol of the failure of British fascism. The second chapter stresses the homogeneity of fascist thinking and the common possession of core ideas, including elitism, racism, and anti-socialism. It suggests that fascist parties also acted in a similar way, they glorified their leaders and encouraged anti-semitism and violence. The chapter argues that postwar fascism recruited especially well among members of the middle class. However, even within this group, only a tiny minority was attracted towards fascism. The third chapter examines the history of the non-fascist organisations, including Labour, the Communist Party and the 43 Group. The chapter also evaluates anti-fascist methods, which involved exposing the fascists, heckling their speakers and turning over fascist platforms. The fourth chapter describes the moment at which fascists and anti-fascists opposed each other in the street. It suggests that the various state agencies, including the police, the Home Office, the law departments and MI6, worked with fascism, or did nothing to prevent its growth. Finally, the Conclusion discusses the obstacles which the fascists faced, including the legacy of the war and the Holocaust, and the success of the Conservative Party after 1945. It also suggests that anti-fascism also played significant part in the fascists' defeat.

Haggith, Toby. "Castles in the air : British film and the reconstruction of the built environment, 1939-51." Thesis, University of Warwick, 1998. http://wrap.warwick.ac.uk/3963/.
Abstract:
This thesis is an examination of British films which discuss and propose the reconstruction of the built enviromnent. It concentrates on the period 1939-51 but also looks at those films made during the inter-war period. It examines how and why the films were produced, and how they present the issues of reconstruction. The particular aims are to see what the films might tell us about the relationship between planners, architects, politicians and the ordinary people - the people who would be the beneficiaries of reconstruction. Secondly, to ascertain what impact the films had on popular attitudes to town planning and building. The main findings are that the films were considered a very important way of communicating with the general public and that they were specifically designed to widen the debate and the process of reconstruction beyond the professionals to ordinary citizens. However, despite these noble and sincere aims the films had only limited effect in achieving this. As a result of studying the production and distribution of the films one has also a better understanding of the relationship between film-makers and the government propaganda agencies to which they were contracted. The most important conclusion from this aspect of the research is that they were highly constrained in the kind of films on reconstruction they could make despite their efforts to produce radical work. Finally the Central Office of Information films of the post-war period show that the Labour Government was similarly committed to involving and informing the people in the new world that they planned to build.

Abstract:
The aim of this article is to illustrate the most relevant results of the philological and textual analysis that I accomplished on a witness of Boccaccio’s Decameron, MS. Firenze, Bibl. Medicea Laurenziana, Plut. 42, 3. The work consisted in an integral collation, based on two Giornate and some loci critici, between Plut. 42, 3 and the most authoritative tradition of Decameron (MSS. Berlin, Staatsbibl., Ham. 90, Paris, Bibl. nationale de France, It. 482 and Firenze, Bibl. Med. Laur., Plut. 42, 1). On one hand, the purpose of this work is to demonstrate that the text transmitted by Plut. 42, 3 is contaminated and altered by errors and innovations, therefore unusable for a new critical edition of the work; on the other hand, it leads us to an investigation into the existence of a «characterizing tradition» of Decameron.

Abstract:
This paper focuses on visions and representations of Italy that emerge from the travel writings and narrative intersections of Sino-Italian mobilities. Taking its primary example from the travels of Zou Taofen (1895-1944), who enshrined his memories of Italy in Pingzong jiyu 萍踪寄语 (Messages from an unending wandering) while exiled from China, this critical exploration of mobility traces the spread of ideas between the Italian Peninsula and the Republic of China. Zou’s new and original visions of Italy reached a broad readership during the republican period, spreading widely and making Zou a “central figure of the New Culture era." Despite his place as one of the most successful and influential journalists in the history of the Republic of China, Zou has not yet “received his full due” (Mitter 2004, 55).

Abstract:
AbstractThe main indications for autoHCT are lymphoid malignancies (90%) with plasma cell disorders (MM and others) comprising 55% of all autoHCT (Passweg et al. 2021). Toxicity and mortality associated with autoHCT have been reduced significantly with the use of mobilized peripheral blood HSC, the extended use of cryotherapy associated with MEL, and the improvements in prophylactic antibiotic and antiemetic regimens. Besides this, outpatient parenteral antimicrobial treatment has been proven feasible and safe, thanks to modern CVC and infusion devices. All these advances have led to the development of outpatient autoHCT programs, and several studies have demonstrated their feasibility and safety (González et al. 2021).

Abstract:
AbstractUnruptured brain AVMs (bAVMs) remain a controversial subject for practicing neurosurgeons, especially in the light of ARUBA and other observational studies. This retrospective study aims to analyze our experience with unruptured bAVMs to see whether it is beneficial in the long-term and how it corresponds to large literature trials. The study comprised 160 adult patients with unruptured bAVMs surgically treated in Burdenko NMC (Moscow) in 2009–2017. Mean age: 33.4 ± 10лет. Clinical presentations were: seizures in 99 (61.9%), chronical headaches—49 (30.6%), ischemic symptoms—4 (2.5%), asymptomatic in 8 (5%) patients. Spetzler-Martin scale: I—18 pt. (11.3%), II—71 pt. (44.4%), III—60 pt. (37.5%), IV—11 pt. (6.8%). Good outcomes (mRS = 0–2) at discharge were achieved in 149 (93.1%), satisfactory (mRS—3)—9 (5.6%). Follow-up was complete for 97 (60.6%) patients, mean—59.3 (13–108 month). Excellent outcomes (mRS = 0–1) reached in 94.8%. For epilepsy patients, Engel I outcome was found in 50 (84.8%); for chronic headaches, 43 (66.1%) patients reported improvement. Postoperative visual field defects were followed in 22 of 55 (40%), complete recovery was reported in 6 (27%) and partial recovery in 8 (36%) patients. Overall, our results support the conclusion that surgery for low-grade bAVMs (S-M I–II) is a beneficial, low-risk option.

In FGF Studies in Small Business and Entrepreneurship, 19–40. Cham: Springer International Publishing, 2022. http://dx.doi.org/10.1007/978-3-031-11371-0_2.
Abstract:
AbstractIn the European Union, SMEs represent as much as 99% of businesses, but only 3 out of 10 companies have some international involvement. EU policy makers perceive SMEs internationalization as a desired path for global growth; thus, they have put forward certain tools which aim to boost the pace and scope of internationalization, i.e., by creating and facilitating access to support activities, sharing information, promoting cluster and networking initiatives, making support schemes consistent throughout the EU, etc. (Della Corte, Handbook of research on startegic Management in Small and Medium Enterprises. IGI Global, 2014). However, a vital point in creating a successful internationalization framework requires understanding that SMEs internationalization models may and do differ from those of multinational enterprises (MNEs). SMEs have a different structure, and they act differently, since their aims vary from those of MNEs (Knight and Liesch, Journal of World Business 51(1): 93–102, 2016; Buckley, Journal of World Business, 51(1): 74–82, 2016).Former studies of European SMEs indicate that there are specific traits of company characteristics that determine their internationalization process. Amongst the distinguished factors, size, activities performed, age, and experience counted as the most significant determinants of the expansion. However, these findings refer to occurrences dating back at least 5 years. In the era of rapid digitalization and—still—ongoing globalization, the impact of these factors might have diminished, making place for others. Therefore, the rising importance of digitalization calls for the need to identify new barriers and opportunities for SMEs to become international.The aim of this chapter is to see whether and how digitalization has influenced the internationalization models of Polish SMEs. We do not provide quantitative analysis that would allow us to statistically verify hypotheses on that matter; however, given the recent developments of the business world and internationalization trends, we assume that digitalization has had an impact on how companies expand abroad nowadays. The study has a screening aim and should allow us to determine whether, in the case of the Polish context, the matter requires further pursuit. The remainder of this chapter is structured as follows: first, we discuss the internationalization models which commonly referred to the international expansion of SMEs. Secondly, we discuss how digitalization can influence the process and its determinants. Finally, we present our research results based on quasi-focus group discussion with Polish SMEs. The study concerned the impact the digitalization has on the internationalization experience of those companies.

Abstract:
AbstractThe analytical method used for the determination of polychlorinated biphenyls (PCB), polychlorinated dibenzo-p-dioxins (PCDD), and polychlorinated dibenzofurans (PCDF) in human milk comprised extraction of lipids, the use of 51 13C12-labelled PCB and PCDD/PCDF as internal standards, several chromatographic purification steps, and high resolution gas chromatographic/high resolution mass spectrometric measurement. As an accredited laboratory since 1998, a comprehensive quality control programme has been applied to assure the long-time reliability of results of human milk samples received for WHO/UNEP-coordinated exposure studies between 2000 and 2019. This included procedural blanks, the use of fortified vegetable oil and numerous quality control samples as an in-house reference material, duplicate analyses, and successful participation in 32 proficiency tests (PTs) covering 81 samples of food of animal origin or human milk. Trueness was estimated from the PT samples in the relevant range for human milk above 1 pg WHO-TEQ/g lipid: The deviation was less than 10% from the assigned values for WHO-PCDD/PCDF-PCB-TEQ and WHO-PCDD/PCDF-TEQ and less than about 15% for WHO-PCB-TEQ for about 90% of the results. For the sum of six non-dioxin-like PCB (relevant occurrence range, 1–1000 ng/g lipid), approximately 90% of the results differed by less than 15% from the assigned values. A long-term precision of <15% (coefficient of variation of within-laboratory reproducibility) was achieved, based on quality control samples analysed between 2000 and 2019.The analytical methodology used fulfilled the requirements of the general criteria for the operation of testing laboratories as laid down in EN ISO/IEC 17025, the analytical criteria for PCDD/PCDF and PCB in feed and food specified in EU legislation, and the criterion for monitoring information for Parties to the Stockholm Convention.

In the UK, one in three women and one in twelve men are likely to have a fracture due to osteoporosis by the age of 90 years. Osteoporosis can affect the whole skeleton but the wrist, hip, and spine are most frequently affected. It is estimated that it costs the NHS and government in the UK over £1.7 billion each year. Bone density can help to determine the risk of fracture and is measured by dual energy x-ray absorptiometry (DEXA)....

Abstract:
Upconversion lasers operate at wavelengths that are shorter than those used for pumping. Efficient upconversion lasing has been achieved in rare earth-doped materials using several different ex citation processes such as sequential two-photon absorption, energy transfer upconversion and a so-called absorption avalanche mechanism; in the latter case, the pump photons are not resonant with absorption from the ground state.1 All these processes involve the use of metastable, intermediate levels which act as a storage reservoir for pump energy. Following the demonstration of the first cw-pumped upconversion laser in 1986, we have achieved upconversion laser operation at violet, blue, green and red wavelengths in several fluoride host crystals doped with Nd3+, Ho3+, Er3+, and Tm3+ ions by pumping with cw dye, Ti:sapphire or diode lasers.1 These upconversion lasers operate at temperatures up to ~ 140 K using pump powers of a few hundred milliwatts. The use of longitudinal pumping of short, monolithic laser crystals resulted in fairly high pump intensities, which is important for these nonlinear excitation processes. Multistep upconversion excitation has been achieved in Er:YLiF4 by producing laser oscillation at 470 nm from the 2P3/2 level whose energy is more than three times higher than that of the 969-nm light used for pumping. At 77 K, green 551-nm laser output was obtained by pumping a 2-mm long Er:YLiF4 crystal with a 809-nm GaAl As diode laser. Recently, green and blue cw upconversion lasing at room temperature has been reported using fluorozirconate fibers doped with Ho3+ and Pr3+, respectively.2

"A 5 kWel Solid Oxide Fuel Cell Stack Operating on Biomass Gasification Producer Gas: System Design and Results." In ASME 2007 International Mechanical Engineering Congress and Exposition. ASMEDC, 2007. http://dx.doi.org/10.1115/imece2007-42570.
Abstract:
This paper describes the system setup and presents results from the ongoing BioSOFC project. The project aims at demonstrating integration of atmospheric biomass steam gasification, high temperature gas cleaning and Solid Oxide Fuel Cells (SOFCs). This is done by taking a slipstream from a steam gasification reactor (the Fast Internally Circulating Fluidised Bed (FICFB) gasifier at Biomasse Kraftwerk Gu¨ssing in Gu¨ssing, Austria) as fuel feed for a 5 kWel Solid Oxide Fuel Cell (SOFC) stack. The system also includes a novel high temperature particle filter (the Panel Bed Filter (PBF)) and a high temperature H2S removal unit. The biomass gasifier, using wood chips as fuel, has a dry producer gas consisting of H2 (up to 45 vol%), CO (up to 30 vol%), CO2 (up to 20 vol%), CH4 (8–12 vol%) and N2 (1–2 vol%). This gas composition makes the producer gas highly suitable as fuel for SOFCs. However, the gas has a relatively high particle loading (up to 60 g/Nm3) and a tar content of up to 2 g/Nm3. In addition, it has been reported that the dry producer gas contains 100–200 ppmv H2S and 500–1000 ppmv NH3. Due to otherwise expected fuel cell performance degradation, the particles have to be removed before entering the SOFC stack. In addition, the sulphur (mainly H2S) concentration must be reduced to minimize the performance degradation in the SOFC. The slipstream is taken from the top of the gasifier freeboard, and is then cooled from about 900°C to 550°C before entering the PBF where the particles are removed. The H2S concentration is reduced in a separate fixed-bed reactor with a Zink-oxide based sorbent. The pressure in the producer gas is increased from the somewhat below atmospheric pressure in the filter to the atmospheric pressure required by the SOFC stack. This pressure increase is achieved by means of two high temperature fans operated at about 525°C. The producer gas is then heated again to up to 900°C before entering the fuel cell stack. This paper presents results from component tests carried out at the Norwegian University of Science and Technology (NTNU) as well as results from the field tests of the system in Gu¨ssing. This ongoing project is scheduled to continue until December 2007. The BioSOFC project is carried out in cooperation with TU-Vienna and Austrian and Norwegian technology companies. The project is funded by the Research Council of Norway and six Norwegian companies.

Jimenez Mori, Raul Alberto. Rural Electricity Access Penalty in Latin America: Income and Location. Inter-American Development Bank, June 2016. http://dx.doi.org/10.18235/0008513.
Abstract:
This paper examines three intrinsic underlying variables affecting the provision of rural electricity services: household income, household location and a country's relative wealth in terms of per capita income. A cross section of nationally representative household surveys from sixteen Latin American countries provides a recent snapshot of access to electricity in the region. This examination shows that despite recent progress in rural electrification, lowincome countries still face significant challenges. Rural electricity coverage is as low as 55% for the poorest income group in some LAC countries, while around 90% of the total access gap is concentrated among the poorest households living in rural areas of low-income countries. Location explains most of the lack of access, however in low-income countries, income is also a key barrier to electrification. These patterns translate into a sizeable electricity access penalty mainly affecting poor households in poor countries, emphasizing the need for effective rural electrification programs to promote inclusive economic growth and social well being.

Abstract:
In November 2022, Wejo Data Services Inc. provided Purdue with a national data set comprised of approximately 470 billion connected vehicle records covering all 50 states for the month of August 2022. The goal of the evaluation data set was to create a series of summary graphics to evaluate the scalability of work zone analytics graphics and electric/hybrid vehicle counts at a national level. This report illustrates several performance measures developed using this dataset for all interstate routes, both state wise and cross-country. State wise graphics are organized with 50 subdirectories containing graphics for each interstate in the 50 states. There are also a series of multi-state graphics for I-5, I-10, I-15, I-35, I-55, I-65, I-75, I-80, I-90, and I-95. Performance measures include absolute and normalized trip counts classified by type of trip (electric vehicle or hybrid vehicle or internal combustion engine vehicle), weekly heatmaps based on vehicle speed overlaid with hard-braking events and finally, speed profiles by interstate mile markers. Additional details on the directories and how to interpret these performance measures can found inside the document (after extracting the .zip file) titled “National_Mobility_Analysis_README.pdf”.

In patients with acute COVID-19, should remdesivir be used compared to placebo? Epistemonikos Interactive Evidence Synthesis, July 2023. http://dx.doi.org/10.30846/ies.sr1000.
Abstract:
The aim was to assess the efficacy of remdesivir in people with acute covid-19 compared with placebo. Eligible studies were randomised trials evaluating the effect of remdesivir versus placebo. We conducted searches in COVID-19 L·OVE (Living OVerview of Evidence) platform, a system that performs regular searches in databases, trial registries, preprint servers and websites relevant to COVID-19. All the searches covered the period until 06/23/2023. No date or language restrictions were applied. Two reviewers independently evaluated potentially eligible studies according to predefined selection criteria, and extracted data on study characteristics, methods, outcomes, and risk of bias, using a predesigned, standardised form. We performed meta-analyses using random-effect models and assessed overall certainty in evidence using the GRADE approach. Results: our search strategy yielded 132 references. 10 randomized controlled trials reported in 15 references met our inclusion criteria and were included in the review. The relative risk of mortality was 0.92 (95% CI 0.83 - 1.01). This means remdesivir reduced the risk of mortality in 8%, compared with placebo. In the studies identified in this review 762 people not receiving remdesivir out of 5340 presented the outcome Mortality (143 per 1000) versus 734 out of 5477 in the group that did receive it, with a risk difference of -12 per 1000 (from -24 to 1). In other words, -12 per 1000 (from -24 to 1) people did not develop the outcome because of the intervention. We assessed the certainty of the evidence for this outcome as low. The estimated absolute effect, -12 per 1000 (from -24 to 1), falls in the range of an effect of small magnitude. The relative risk of mechanical ventilation requirement was 0.71 (95% CI 0.41 - 1.24). This means placebo reduced the risk of mechanical ventilation requirement in 29%, compared with . In the studies identified in this review 189 people not receiving placebo out of 989 presented the outcome Mechanical ventilation requirement (191 per 1000) versus 182 out of 1195 in the group that did receive it, with a risk difference of -55 per 1000 (from -113 to 46). In other words, -55 per 1000 (from -113 to 46) people did not develop the outcome because of the intervention. We assessed the certainty of the evidence for this outcome as very low. The estimated absolute effect, -55 per 1000 (from -113 to 46), falls in the range of an effect of moderate magnitude. The relative risk of serious adverse events was 0.74 (95% CI 0.57 - 0.95). This means reduced the risk of serious adverse events in 26%, compared with . In the studies identified in this review 265 people not receiving out of 1238 presented the outcome Serious adverse events (214 per 1000) versus 256 out of 1401 in the group that did receive it, with a risk difference of -56 per 1000 (from -91 to -10). In other words, -56 per 1000 (from -91 to -10) people did not develop the outcome because of the intervention. We assessed the certainty of the evidence for this outcome as moderate. The estimated absolute effect, -56 per 1000 (from -91 to -10), falls in the range of an effect of moderate magnitude. Conclusions: Remdesivir may result in a slight reduction in Mortality. Remdesivir may reduce the Mechanical ventilation requirement but the evidence is very uncertain. Remdesivir probably results in a reduction in Serious adverse events.

Investigating the influence of demographics and personality types on practitioners' level of systems thinking skills. Engineer Research and Development Center (U.S.), March 2022. http://dx.doi.org/10.21079/11681/43622.
Abstract:
Although the application of systems thinking (ST) has become essential for practitioners when dealing with turbulent and complex environments, there are limited studies available in the current literature that investigate how the ST skills of practitioners vary with regard to demographic factors and personality types (PTs). To address this gap, this article uses a structural equation modeling approach to explore the relationship be-tween practitioners’ ST skills, PT, and a set of demographic factors. The demographic factors included in the study are education level, the field of the highest degree, organizational ownership structure, job experience, and current occupation type. A total of 99 engineering managers, 104 systems engineers (SEs), and 55 practitioners with other occupations participated in this article. Results showed that the education level, the field of the highest degree, PT, organizational ownership structure, and current job experience of practitioners influenced their level of ST skills. Additionally, the current occupation type of practitioners partially affects their level of ST skills. An in-depth analysis was also conducted using multiple group analysis to show how seven ST skills of the practitioners vary across their level of education. Taken together, the findings of the study suggest that PT and a set of demographic factors influence the overall ST skill of the practitioners.

Abstract:
Cationic polypeptide proteins found in the seeds of the tropical plant Moringa oleifera have coagulation efficiencies similar to aluminum and ferric sulfates without their recalcitrant nature. Although these proteins possess great potential to augment or replace traditional coagulants in water treatment, harvesting active protein from seeds is laborious and not cost-effective. Here, we describe an alternative method to express and secrete active M. oleifera coagulant protein (MO) in Bacillus subtilis. A plasmid library containing the MO gene and 173 different types of secretory signal peptides was created and cloned into B. subtilis strain RIK1285. Fourteen of 440 clones screened were capable of secreting MO with yields ranging from 55 to 122 mg/L of growth medium. The coagulant activity of the highest MO secreting clone was evaluated when grown on Luria broth, and cell-free medium from the culture was shown to reduce turbidity in a buffered kaolin suspension by approximately 90% compared with controls without the MO gene. The clone was also capable of secreting active MO when grown on a defined synthetic wastewater supplemented with 0.5% tryptone. Cell-free medium from the strain harboring the MO gene demonstrated more than a 2-fold reduction in turbidity compared with controls. Additionally, no significant amount of MO was observed without the addition of the synthetic wastewater, suggesting that it served as a source of nutrients for the effective expression and translocation of MO into the medium.

Abstract:
In January 2023, Wejo Data Services Inc. provided Purdue with a national data set comprised of approximately 503 billion connected vehicle records covering all 50 states for the month of December 2022. The goal of the evaluation data set was to create a series of summary graphics to evaluate the scalability of work zone/winter weather analytics graphics and electric/hybrid vehicle counts at a national level as well as visualize the mobility impacts of winter weather activity on the national interstate network. This report illustrates several performance measures developed using this dataset for all interstate routes, both state wise and cross-country. Statewide graphics are presented for each interstate in the 50 states. There are also a series of multi-state graphics for I-5, I-10, I-15, I-35, I-55, I-65, I-75, I-80, I-90, and I-95 and selected other routes that witnessed winter storm impacts. Performance measures include absolute and normalized trip counts classified by type of trip (electric vehicle or hybrid vehicle or internal combustion engine vehicle), weekly heatmaps based on vehicle speed (for the two-week period from December 12-25, 2022) and finally, speed profiles by interstate mile markers. Traffic tickers depicting miles of congestion as well as mile-hours of congestion for the national interstate network and selected multi-state routes are also included to provide a unified visual of nationwide mobility impact of recurring congestion as well as non-recurring congestion caused by winter weather. The generated performance measures can be found in the supplemental files.
