Pomysły na „nowy porządek świata”: podróż Karola IV na koronację cesarską do Rzymu w świetle korespondencji Niccolò Acciaiuoliego i Petrarki
Authors: Schlotheuber Eva 
Published: August 2020

Koronacja cesarska Karola IV w 1355 r. była dotąd powszechnie uważana przez badaczy za wydarzenie mało istotne i bez większego wpływu na przyszłość. W rzeczywistości było jednak odwrotnie. Podróż koronacyjna Karola IV musi być rozpatrywana w szerszym kontekście walki o władzę we Włoszech między Świętym Cesarstwem Rzymskim a papiestwem. W artykule przeprowadzono analizę skomplikowanej sytuacji z perspektywy Karola oraz jego przeciwników i zwolenników we Włoszech. Ukazano, jak koronacja cesarska Karola IV doprowadziła do zasadniczej zmiany układu sił politycznych we Włoszech i w Europie, co skutkowało w konsekwencji wydaniem Złotej Bulli (1356) i Konstytucji egidiańskich (1357). Autorka po raz pierwszy odwołuje się w swoich rozważaniach do nieznanego wcześniej listu Niccola Acciaiuoliego, który kierował polityką Królestwa Neapolu. List ten rzuca nowe światło na taktykę opozycyjnego stronnictwa gwelfów i wpływu obecności Karola w Rzymie na jego polityczne cele. W artykule postarano się również udzielić odpowiedzi na od dawna przykuwające uwagę uczonych pytanie, dlaczego Karol nie zaakceptował prośby Petrarki, aby podjął we Włoszech działania na rzecz obrony tego, co określano mianem res publica, i dlaczego humanista nie przyjął zaproszenia, aby towarzyszyć Karolowi w jego podróży do Rzymu.
Pamięć lat nazizmu w niemieckim filmie fabularnym lat 1946–1965
Authors: Klejsa Konrad 
Published: August 2020

W jaki sposób niemieccy twórcy filmowi dwóch pierwszych dziesięcioleci po zakończeniu II wojny światowej opowiadali o niedawnej przeszłości? Które tematy z nią związane były szczególnie często podejmowane w filmach fabularnych, a jakie pozostały przemilczane? W jaki sposób bieżąca polityka oddziaływała na audiowizualne reprezentacje autentycznych wydarzeń oraz fikcjonalne narracje osadzone w realiach III Rzeszy? Na te pytania próbuje odpowiedzieć autor niniejszej książki. Została ona podzielona na trzy części: okres do 1949 r. (filmy powstałe w strefach okupacyjnych), kinematografie Niemieckiej Republiki Demokratycznej do połowy lat 60. (cezurą jest XI Plenum Komitetu Centralnego SED) oraz Republiki Federalnej Niemiec (do pojawienia się tzw. Nowego Kina Niemieckiego). Walorem pracy jest komparatystyczne zintegrowanie rozważań dotyczących kina RFN i NRD wokół kilku zagadnień tematycznych, m.in. mitu o „dobrym Wehrmachcie”, przedstawień ruchu oporu oraz reprezentacji obozów koncentracyjnych. Bazę źródłową monografii stanowi ponad sto pełnometrażowych filmów fabularnych oraz najważniejsze recenzje opublikowane w głównych tytułach prasowych obu krajów.

High self-efficacy is needed so that patients will be motivated to take therapy programs, increase their self-esteem and desire for recovery. The purpose of this study is to determine the self-efficacy improvement of post-stroke patients when provided with life review therapy. This study was quasi-experimental. A purposive sampling technique was used to collect the data, with a sample of 60 respondents (30 controls and 30 interventions). Data was collected using a stroke self-efficacy questionnaire. The statistical tests used were Wilcoxon and Mann Whitney. The patient's self-efficacy in the intervention group showed a change in category in the post-test result (before the intervention it was mostly in the moderate category, after the intervention it went into the high category) with statistical test results p=0.00. The control group remained mostly in the moderate category on both pre-test and post-test results with statistical test results p=0.002. There was a comparison of the effectiveness of applying life review therapy between the two groups (p=0.000). The results of this study indicate that the administration of life review therapy can improve the self-efficacy of patients after a stroke.</span></span></p>

The composites of hydroxyapatite and SiO2 were successfully synthesized. The hydroxyapatite was prepared from golden snail shells (Pomacea canaliculata L). The hydroxyapatite and hydroxyapatite-SiO2 composites were characterized using XRD, FTIR, SEM-EDS. Furthermore, hydroxyapatite and hydroxyapatite-SiO2 composites were used to remove Pb(II) from aqueous solution. Various adsorption parameters such as pH of the solution, contact time, and initial Pb(II) concentration were used to study the adsorption process. The optimum pH of the solution for removal of Pb(II) by hydroxyapatite and hydroxyapatite-SiO2 composite at pH 6 and contact time at 60 minutes. Both adsorbents follow the Langmuir isotherm. The maximum adsorption capacity of the hydroxyapatite-SiO2 composite is greater compare to hydroxyapatite, respectively 135.14 and 123.46 mg/g. The pseudo-second order kinetic model had a correlation coefficient (R2) greater than the pseudo-first order so pseudo-second order kinetic is better to describe adsorption kinetics

Background:Giant-cell tumor of bone (GCTB) is a locally aggressive intermediate bone tumor with a rarely metastasizing disposition. Standard surgical treatment consists of curettage, adjuvant treatment, and augmentation with allograft, autograft, or synthetics. Polymethylmethacrylate (PMMA) has been widely used for augmentation of the bone defect; however, the hyperthermic polymerization of PMMA may cause damage to articular cartilage, and the stiffness of the material may decrease the ability of the joint to absorb shock. These properties were reported to result in secondary osteoarthritis. Calcium phosphate cement has a low degree of thermal reaction and a strength that is similar to cortical bone. The aim of the present study was to investigate the incidence of secondary osteoarthritis around the knee joint following augmentation with calcium phosphate cement.Methods:We retrospectively evaluated 19 patients with primary GCTB from 2003 to 2012. Curettage, high-speed burring, phenolization, and filling with calcium phosphate cement were performed in all patients. Radiographic evidence of osteoarthritis progression was evaluated with use of the Kellgren-Lawrence grade; the postoperative grade was compared with both the preoperative grade and the grade of the nonoperative contralateral knee at the time of the latest follow-up. The Musculoskeletal Tumor Society score and oncological outcomes at the time of the latest follow-up were evaluated.Results:At a median follow-up period of 131 months, osteoarthritic progression was observed in 5 patients (26%), of which 2 were classified as Kellgren-Lawrence grade 3 and 1 was classified as Kellgren-Lawrence grade 4. The patient with grade-4 osteoarthritis underwent total knee arthroplasty, and 1 of the patients with grade-3 osteoarthritis underwent open-wedge high tibial osteotomy. The 10-year survival rate of joint cartilage with a Kellgren-Lawrence grade of <3 was 83%. The average Musculoskeletal Tumor Society score was 29 points. GCTB recurred in 2 patients, and 1 of these patients developed pulmonary metastasis.Conclusions:The incidence of secondary osteoarthritis was low, despite the long follow-up period. Prospective investigation comparing PMMA and calcium phosphate cement is warranted to determine the relative rate of secondary osteoarthritis and the outcomes associated with the 2 different types of augmentation.Level of Evidence:TherapeuticLevel IV.

Классификация методов формообразования и синтез на ее основе схем обработки профильных моментопередающих поверхностей

The paper presents characteristics of the known classifications of surface shaping methods in mechanical engineering during mechanical and physical-technical processing; according to the classifications a surface shaping method is considered as a combination of methods for generating its producing lines – generatrix and guide – provided that the generation rate of the generatrix is higher than the guide. The advantages of constructing a classification and a formalized description of surface shaping methods have been shown in the paper; each of them represents a combination of surface formation methods in cross section and in length, regardless of generation speed for generatrix and guide lines. This increases information content of the description for a shaping method which is important for comparing methods of shaping surfaces and synthesis of schemes for their processing in the functional design of the machine. The paper has revealed the fact that in comparison with the well-known classification of A. A. Fedotenka it is an expedient to introduce methods of bending, intermittent track and intermittent rolling, as well as combined methods combining advantages of their basic methods which expand the synthesis of progressive processing schemes for profile surfaces. The introduction of the methods has been made in many basic methods of generating production lines (copying, following, touching and rolling). Based on the expanded set of basic methods and the accepted principle of presenting the methods of shaping profile surfaces, their classification has been developed as the basis for systematization and synthesis of known and possible shaping methods. The paper considers examples of rational shaping method synthesis based on the proposed classification and progressive processing schemes for profile moment-transmitting surfaces on the basis of synthesis examples. In particular, the use of an envelope method instead of the applied rolling method has made it possible to simplify significantly a tool design, to increase its versatility and accuracy in formation of moment-transmitting surfaces with a profile in the form of a Relo triangle.
Macondo Changed BOPs But There Is a Limit
Authors: Rassenfoss Stephen 
Published: August 2020

There is a limit to disruptive innovation in oilfield technology. Blowout preventers (BOP) show how hard it can be.
A decade ago on 20 April 2020, the Macondo disaster made a powerful case for change when this last line of defense failed to stop a blowout that caused explosions and a fire that killed 11, destroyed the Deepwater Horizon drilling rig, and set off one of the largest oil spills ever in the Gulf of Mexico.
Scathing reports from investigations and staggering payouts from lawsuits against BP and other companies highlighted the shortcomings of machines that failed to serve as the last line of defense when natural gas surged onto the drilling floor, setting off a series of explosions.
The investigations highlighted a long string of errors that led to the avoidable crisis. There was a failure to verify the cementing, missed signs of gas building up in the well, and a delayed decision to activate the BOP until the explosions already may have severed the hydraulic lines to the wellhead.
But the simple explanation for it all: The shear rams failed to sever the pipe and seal the well.
In the aftermath, well-control standards and regulations were rewritten and expanded. The changes required that old recommendations became requirements, and new ones were added, including a strong push toward real-time monitoring.
The reports did not propose fundamentally redesigning BOPs.
But for engineers with an inventive streak, this looked like a call to rethink the driving force behind these hydraulic devices where the fundamentals have changed little since the first patent was issued nearly 100 years ago.
The arguments for rethinking BOPs included a 2003 study by West Engineering Services that found shear rams failed 7.5% of the time based on an estimate of the typical force required to cut pipe at the time. The force needed rises as casing gets tougher, water depths deeper, and well pressures higher, according to the study funded by what is now the US Bureau of Safety and Environmental Enforcement (BSEE).
A Det Norske Veritas study for Transocean completed before the Macondo blowout found 11 situations where a BOP was activated in an emergency among the 15,000 wells drilled from 1980 to 2006. The BOPs only worked six times during that period, according to a story in The New York Times published in June 2010 - while the industry was scrambling to find a way to stop the Macondo leak.
Different Perspectives
The innovators range from startups to major offshore drillers.
A Norwegian engineer started a company to sell a design for all-electric BOP stacks and an offshore drilling contractor developed an electric motor to retrofit into a BOP body.
Engineers with military and space experience created cutting devices powered by gas generators using solid chemical propellants that send out high-pressure streams of gas when ignited by an electrical signal, similar to the deployment of an airbag or the thrusters on the Space Shuttle (this technology has been around for a long time).
Rethinking Exploration
Authors: Feder Judy 
Published: August 2020

“Down but not out” is how Westwood Global Energy Group described exploration drilling in an article based on its State of Exploration 2020 Report. The Baker Hughes rig count provides supporting details. On 12 May, the data showed 339 active rigs in the United States - the lowest level since the rig count was introduced in 1987. On 1 June, the US count plunged to 301 in its 12th week of losses. At the worst of the 2014-2016 oil bust - the previous lowest point on record - 404 rigs were operating.
The worldwide rig count for May was 1,176, down 338 from the 1,514 counted in April and down 1,006 from the 2,182 counted in May 2019. And, Rystad predicted on 28 May that more than half of the world’s planned licensing rounds for 2020 are likely to be canceled.
The consensus among industry experts is that exploration will be hit by some of the deepest cuts inflicted by the coronavirus pandemic, the biggest oil market crash in history, and the transition to a low-carbon energy future. The silver lining is that there is still a business case for exploration despite these difficult times. Julie Wilson, director of global exploration research for Wood Mackenzie, said in a recent virtual panel discussion that the role of exploration in replacing supply sources in current portfolios with “new and better” barrels of oil equivalent (BOE) will continue over the next 20 years. But for explorers to prosper, those barrels will need to be low in cost and emissions.
Rude Awakening
For the exploration sector, 2020 began with a degree of cautious optimism and increasing activity. Confidence had returned with improved performance, the highest commercial success rate (CSR) in 10 years, and the discovery in 2019 of several multi-billion-barrel plays. Explorers were keenly aware of challenges ahead, including investability, capital efficiency, the risks of exploring in deep water, and societal pressure to move toward energy transition. But, the overall outlook was for another 30 years of profitable exploration.
At the start of the year, the high-impact well count had been expected to be similar or slightly higher than the 93 wells completed in 2019. Westwood now expects around 60 to 70 high-impact exploration wells to be completed by the end of 2020, a decline of up to 35% and back to the numbers and volumes seen from 2016 to 2018 following the 2014 oil price crash. In the Gulf of Mexico (GOM), the number of executed high-impact wells has declined from 34 to 15, all in deep water. Seven of those have been spudded. For independent GOM explorers, the number of expected wells went from 13 to one, as companies decided to focus their bare-minimum budgets on near-term production.
