Published: March 2024

Abstract. The processes responsible for methane (CH4) emissions from boreal wetlands are complex; hence, their model representation is complicated by a large number of parameters and parameter uncertainties. The arctic-enabled dynamic global vegetation model LPJ-GUESS (Lund–Potsdam–Jena General Ecosystem Simulator) is one such model that allows quantification and understanding of the natural wetland CH4 fluxes at various scales, ranging from local to regional and global, but with several uncertainties. The model contains detailed descriptions of the CH4 production, oxidation, and transport controlled by several process parameters. Complexities in the underlying environmental processes, warming-driven alternative paths of meteorological phenomena, and changes in hydrological and vegetation conditions highlight the need for a calibrated and optimised version of LPJ-GUESS. In this study, we formulated the parameter calibration as a Bayesian problem, using knowledge of reasonable parameters values as priors. We then used an adaptive Metropolis–Hastings (MH)-based Markov chain Monte Carlo (MCMC) algorithm to improve predictions of CH4 emission by LPJ-GUESS and to quantify uncertainties. Application of this method on uncertain parameters allows for a greater search of their posterior distribution, leading to a more complete characterisation of the posterior distribution with a reduced risk of the sample impoverishment that can occur when using other optimisation methods. For assimilation, the analysis used flux measurement data gathered during the period from 2005 to 2014 from the Siikaneva wetlands in Southern Finland with an estimation of measurement uncertainties. The data are used to constrain the processes behind the CH4 dynamics, and the posterior covariance structures are used to explain how the parameters and the processes are related. To further support the conclusions, the CH4 flux and the other component fluxes associated with the flux are examined. The results demonstrate the robustness of MCMC methods to quantitatively assess the interrelationship between objective function choices, parameter identifiability, and data support. The experiment using real observations from Siikaneva resulted in a reduction in the root-mean-square error (RMSE), from 0.044 to 0.023 gC m−2 d−1, and a 93.89 % reduction in the cost function value. As a part of this work, knowledge about how CH4 data can constrain the parameters and processes is derived. Although the optimisation is performed based on a single site's flux data from Siikaneva, the algorithm is useful for larger-scale multi-site studies for a more robust calibration of LPJ-GUESS and similar models, and the results can highlight where model improvements are needed.
Understanding snow saltation parameterizations: lessons from theory, experiments and numerical simulations
Authors: Melo Daniela Brito , Sigmund Armin , Lehning Michael
Published: March 2024

Abstract. Drifting and blowing snow are important features in polar and high mountain regions. They control the surface mass balance in windy conditions and influence sublimation of snow and ice surfaces. Despite their importance, model representations in weather and climate assessments have high uncertainties because the associated physical processes are complex and highly variable in space and time. This contribution investigates the saltation system, which is the lower boundary condition for drifting and blowing snow models. Using a combination of (previous) measurements and new physics-based modeling with large-eddy simulation (LES), we show that the prevailing parameterizations that describe the saltation system in atmospheric models are based on contradictory assumptions: while some scaling laws are typical of a saltation system dominated by aerodynamic entrainment, others represent a saltation system controlled by splash. We show that both regimes can exist, depending on the friction velocity. Contrary to sand saltation, aerodynamic entrainment of surface particles is not negligible. It is important at low wind speeds, leading to a saltation height and near-surface particle velocity which increase with the friction velocity. In a splash-dominated saltation regime at higher friction velocities, the saltation height and near-surface particle velocity become invariant with the friction velocity and closer to what is observed with sand. These findings are accompanied by a detailed description of the theoretical, experimental and numerical arguments behind snow saltation parameterizations. This work offers a comprehensive understanding of the snow saltation system and its scaling laws, useful for both modelers and experimentalists.
Wind turbine rotors in surge motion: new insights into unsteady aerodynamics of floating offshore wind turbines (FOWTs) from experiments and simulations

Published: March 2024

Abstract. An accurate prediction of the unsteady loads acting on floating offshore wind turbines (FOWTs) under consideration of wave excitation is crucial for a resource-efficient turbine design. Despite a considerable number of simulation studies in this area, it is still not fully understood which unsteady aerodynamic phenomena have a notable influence on the loads acting on a wind turbine rotor in motion. In the present study, investigations are carried out to evaluate the most relevant unsteady aerodynamic phenomena for a wind turbine rotor in surge motion. As a result, inflow conditions are determined for which a significant influence of these phenomena on the rotor loads can be expected. The experimental and numerical investigations are conducted on a two-bladed wind turbine rotor subjected to a tower-top surge motion. A specialised wind tunnel test rig has been developed to measure the aerodynamic torque response of the rotor subjected to surge motions with moderate frequencies. The torque measurements are compared to two free-vortex-wake (FVW) methods, namely a panel method and a lifting-line method. Unsteady contributions that cannot be captured using quasi-steady modelling have not been detected in either the measurements or the simulations in the covered region of motions ranging from a rotor reduced frequency of 0.55 to 1.09 and with motion velocity amplitudes of up to 9 % of the wind speed. The surge motion frequencies were limited to a moderate range (5 to 10 Hz) due to vibrations occurring in the experiments. Therefore, a numerical study with an extended range of motion frequencies using the panel and the lifting-line method was performed. The results from both FVW methods reveal significant unsteady contributions of the surge motions to the torque and thrust response that have not been reported in the recent literature. Furthermore, the results show the presence of the returning wake effect, which is known from helicopter aerodynamics. Additional simulations of the UNAFLOW scale model and the IEA 15 MW rotor demonstrate that the occurrence of the returning wake effect is independent from the turbine but determined by the ratio of 3P and surge motion frequency. In the case of the IEA 15 MW rotor, a notable impact of the returning wake effect was found at surge motion frequencies in the range of typical wave periods. Finally, a comparison with OpenFAST simulations reveals notable differences in the modelling of the unsteady aerodynamic behaviour in comparison to the FVW methods.

The paper considers the possibility of using the Time Difference of Arrival (TDOA) method, which can be applied to confirm the reliability of information coming from multiple sources. TDOA method can be applied to validate the information received from several ground automatic dependent surveillance stations of broadcast type (ADS-B). The paper is aimed at studying the TDOA method and its application to ADS-B stations. This method makes it possible to use the ADS-B as the only means of surveillance at the airfield. Currently, according to ICAO recommendations, ADS-B stations are not allowed to be used as a stand-alone surveillance aid due to the problems related to the possibility of distorting a signal or introducing some false information into messages, so the operation of this type of stations is possible only together with other means of surveillance, such as multi-position surveillance systems (MLAT) or secondary surveillance radar systems (SSR) thus increasing the cost of organizing surveillance on the airfield. Thus, the relevance of the work is related to the need to find an alternative method of confirming the validity of an ADS-B message.

Slavoj Žižek. Repetir Bakunin
Authors: Gómez Villar Antonio
Published: March 2024

La pregunta que articula este artículo es acerca del tipo de sujeto que se esconde tras los requisitos formales del acto en Žižek. ¿Quiénes son los sujetos empíricos implicados en su concepción de acto? El acto lo es sin sujeto, carece de explicación causalista; sin embargo, si bien no aporta una noción positiva con contornos específicos y un contenido determinado, sí existe una dimensión sociológica implícita. ¿Dónde ubica sociológicamente ese “universal concreto”? Si el efecto más inmediato de lo que Žižek denomina “posmodernismo” es la despolitización de la economía, ¿Quién es, entonces, el agente de la repolitización? ¿qué podría ocupar hoy el lugar de “posición proletaria”? Argumentamos que si bien Žižek se propone repetir Lenin contra las concepciones economicistas, su apuesta por el lumpen como “individuo universal” lo aproxima más bien a los planteamientos bakunianos contra Marx, al observar en las figuras de la exclusión un potencial sujeto revolucionario.
The Death of the Heavens: Crescas and Spinoza on the Uniformity of the World
Authors: Sánchez de León Serrano José María
Published: March 2024

The paper examines the roles of Crescas and Spinoza in the transition from the medieval to the modern conception of the universe. Crescas is presented as an illustrative example of the tension between Aristotelianism and revealed religion and how the latter brings about the dissolution of the former, thus paving the way for the modern conception of the universe. It is then showed how this modern conception is embodied in Spinoza’s thought, which radicalizes some of its defining traits. This radicalization undermines the traditional conception of the Deus absconditus and leads in Spinoza to the replacement of religion by philosophy as the true divine revelation.

Published: March 2024

False information on Jordanian news websites lures readers through their inaccurate headlines to click on them in order to access the content, shock and impress them, regardless of the effects it has on these people when they discover that they are dealing with false news. This research aims to identify the methods used by journalists on Jordanian news websites to deal with false information. The methodology of this study is based on the descriptive analytical approach, through which a literature review of certain terms related to the problem and four interviews with editors of some Jordanian news websites were conducted. The results show that there is a consensus that the veracity of the news should be ensured before publication by the editors of these news websites, without resorting to appropriating information from other news websites and verifying its authenticity. To conclude, several recommendations are made to avoid disinformation, among which it is worth highlighting that there should be legal protection for the information issued by news websites and harsh penalties for false information published on them.
De la esperanza a la crítica constante: la relación prensa–poder político en la Ciudad de México

Published: March 2024

Entre violencia y cuestionamientos a su trabajo, los periodistas mexicanos producen noticias diariamente. No siempre atendemos cómo lo hacen o sus impresiones al respecto, cuando hacerlo enriquecería la comprensión de su profesión y de sus vínculos con otros actores. Partiendo de 42 entrevistas en profundidad a periodistas de la Ciudad de México, este artículo analiza la manera en que perciben su relación con el poder político. Desde el enfoque de la Teoría Fundamentada, los hallazgos se dividen en cinco rubros: “esperanza” de mejores condiciones laborales bajo este gobierno; cambios en rutinas derivados de políticas de esta administración; restricciones, como falta de transparencia y censura; dependencia de publicidad oficial que genera incertidumbre ante la necesidad de recursos, y malestar por críticas que reciben del gobierno. Resultados que surgen de negociaciones con el poder y que abonan a la literatura acerca de la labor periodística en el contexto sociopolítico mexicano actual.

Azoospermia - An Overview
Authors: Sinwal Aashutosh , Bhardwaj Mudit , Nair Mohit
Published: March 2024

The lack of sperm in the ejaculate is the hallmark of azoospermia. 15% of male infertile individuals have azoospermia. Obstructive azoospermia (OA) and non-obstructive azoospermia (NOA) are the two main types of azoospermia. Infertility is a widespread chronic condition that affects mostly people aged 25 to 44, accounting for around 15% of all couples worldwide. The specific causes of azoospermia are not often obvious, but when the pathophysiology is idiopathic, the sickness is primarily linked to difficulties with ciliary function and mucus quality. The lack of gonadotropin production or intrinsic testicular dysfunction might be the reason for the NOA analysis. Silber and Owen developed microsurgical procedures for treating obstructive azoospermia in 1977, which have since become the norm for reconstructive surgery in male reproductive tract disorders. Micro TESE, an innovative method based on microsurgical procedures, is successful for sperm retrieval in males with NOA having ICSI.

Abstract
In this research work, the main distillation column of Salahadin 1 refinery in Baiji Refineries is simulated and analyzed using Aspen HYSYS. Kirkuk, Basrah and Ajeel crudes are mixed together (with unknown mixing ratio) to create the feed stream of this unit. The determination of the blending ratio of these streams beside performance analysis of the system using actual plant data to increase the operating capacity are the main objectives of this research work. So, this work is very helpful to the refinery because it can be applicable to manage these blending ratios to obtain desired product quality. Also, this work enables the CDU unit at the refinery to work at full capacity. The validation results show that the system is perfectly simulated with Aspen HYSYS and the mixing ratio of (Ajeel, Basrah, and Kirkuk) crudes are (0.102,0.5, and 0.398) respectively; Furthermore, this study suggested that, it is important to replace the transfer line pipe diameter between the furnace and the distillation column according to the design specifications which enables the operators to rise the feed volumetric flowrate into full capacity.

RESOURCE-SAVING RUN-IN OF INTERNAL COMBUSTION ENGINES
AT USE OF OIL MODIFYING ADDITIVES
Authors: IVANOV V. , VIGERINA T.
Published: March 2024

Using the example of the cold stage of running-in of a D-245 diesel engine on a running-brake stand KI-2139B

at a crankshaft speed of the engine being run in within 700±10 min–1, it was established that the use of additives to lubricating

oils allows reducing the break-in time by 1,5 times. Cold running-in of diesel engines at a repair facility using

M-10G2 oil with the SURM KV additive containing 3,2–3,4% at a supply oil temperature of 55–65 °C requires a duration

of 60 minutes. The use of the SURM KV additive makes it possible to obtain compression pressures during cold

running that are the same as during hot running at idle using the basic technology. The exclusion of the hot running-in

mode at idle speed from the technological process of running-in diesel engines is justified. The economic effect of introducing

special additives into the lubricant during running-in of internal combustion engines is to reduce its time and

reduce fuel consumption.

La Medicina Traslazionale: un ponte tra laboratorio e letto del paziente?
Authors: De Brasi Daniele
Published: March 2024

Translational Medicine: a bridge between bench and patient bedside? Translational medicine (TM) can be defined as the interdisciplinary application of biomedical research for the improvement of health of patients and society. The focus of TM has so far been largely on the bench-to-bedside rather than bedside-community transition of research. Several “Valleys of Death” in this process have been described, identifying transitional failures that may halt or impede the pathway, which would otherwise lead to the development of medicines, technologies, and/or evidence-based practice guidelines. In order to help bridge these gaps, increasing patient-orientated research at each stage could improve the success of projects and increase societal impact. Increasing the accessibility and involvement of patients in TM outside of traditional research centers, such as universities and teaching hospitals, is one crucial pre-requisite. For example, where clinical research units with active links to local universities have been set-up, research participation can be increased. Such non-traditional research centers (NRTCs) might include primary or secondary care services, or even social care institutions. TM professionals (TMPs) from multi-disciplinary backgrounds, with work experience in university or research centers and with experience of TM, could play a vital role in this organizational change. TMPs in NTRCs are well placed to collaborate with local universities, larger research centers and commercial research and development organizations. Exchanging information could benefit all shareholders involved. TMPs can also stimulate the education and innovative thinking that is required for TM to achieve its full societal impact. We discuss the scope of a potential role for TMPs in NTRCs, as well as the possible barriers and difficulties they might face, along with measures that could widen the accessibility of TM outside of the traditional setting.
Nietzsche Contra the Naturalists
Authors: Sherman David
Published: March 2024

Even among scholars who emphasize Nietzsche’s naturalism (“the naturalists”), what it actually involves is disputed. This article identifies the foundations of Nietzsche’s naturalism and then elaborates on these foundations through a critical analysis of the works of those naturalists who also identify them. Nietzsche is a methodological naturalist, who, epistemically, is a reliabilist, and while he acknowledges the innate limitations of our cognitive inheritance, which is reflected in his perspectivism, he sees no reason to conclude that we cannot grasp the natural world truly. As to the primary issue in scientific explanation, causation, Nietzsche adopts a regularity theory as early as The Gay Science, and, on the basis of this theory, rejects determinism. One consequence of this analysis is that Nietzsche’s naturalism is not as restrictive as the naturalists tend to portray it, and this opens up new possibilities for interpreting many of his other commitments.

تهدف الدراسة إلى تطوير السياسات التعليمية لنظام التعليم العام في فلسطين في ضوء خبرة فنلندا. وقد تم اعتماد المنهج  المقارن كمسار منهجي شامل يتضمن مداخل متعددة للمعالجة التربوية المقارنة، وأشارت نتائج الدراسة إلى  عدم وضوح رؤية وفلسفة التعليم الفلسطينية، واعتماد مصادر تمويل التعليم على الجهات المانحة، وتدني الميزانية المخصصة للتعليم من إجمالي الدخل القومي الفلسطيني، وتردي أوضاع المعلمين وأجورهم، وكثافة الطلبة في الصفوف الدراسية مما يقلل من فرص تقديم الدعم الفردي لهم ومن اكتشاف مواهبهم ورعايتهم، وضعف شراكة المجتمع في صنع القرارات وتصميم المناهج، وضعف جودة برامج التدريب وتعدد الجهات المسؤولة عنها، وعدم الإفادة من نتائج تقارير المتابعة والتقييم ، وغياب دور السلطات المحلية والبلديات في تمويل التعليم وإدارة شؤونه على مستوى المحافظات، وفي ضوء ذلك طورت الباحثة عددا من السياسات التربوية بالإفادة من الخبرة الفنلندية، وتوصي الدراسة بتبني تلك السياسات والعمل بها كإطار مرجعي موحد.
YÖNETİCİ DESTEĞİ İLE ÖRGÜTSEL MUHALEFET ARASINDAKİ İLİŞKİ: BU İLİŞKİDE ÖRGÜTSEL ÇEKİCİLİĞİN ARACILIK ROLÜ
Authors: Yılmaz Kılıçkaya Fatma
Published: March 2024

Organizasyonlar, içinde artan çeşitlilik ve karmaşıklığın karakterize edildiği günümüzün çağdaş manzarasında, iletişim, destek ve muhalefet konularına büyük önem verilmektedir. Bu kavramların önemi göz önüne alındığında, bu çalışma, yönetsel destek ile örgütsel muhalefet arasındaki ilişkiyi incelemeyi ve aynı zamanda örgütsel çekiciliğin aracı rolünü de göz önünde bulundurmayı amaçlamaktadır. Bu amaca ulaşmak için, çalışmada 323 kamu görevlisinden oluşan bir örneklemden veri toplamak için anket yöntemi kullanılmıştır. Toplanan veriler daha sonra istatistiksel yazılım paketi SPSS 24 kullanılarak analiz edilmiştir. Analizin sonuçlarına göre ilk olarak yönetici desteğinin hem örgütsel muhalefet hem de örgütsel çekicilik üzerinde olumlu bir etki gösterdiği belirlenmiştir. Ayrıca analiz, örgütsel çekicilik ve örgütsel muhalefet arasındaki ilişkinin pozitif olduğunu göstermiştir. Çalışma ek olarak yönetici desteği ve örgütsel muhalefet arasındaki ilişkide örgütsel çekiciliğin aracılık etkisini de tespit etmiştir. Kamu sektöründe yönetici desteği, örgütsel çekicilik ve örgütsel muhalefet arasındaki ilişkiye daha önce değinilmemiş olması literatürdeki boşluğu dolduracaktır. Elde edilen bulgular başta kamu kurumları olmak üzere çağdaş organizasyonlarda yönetici desteği, örgütsel çekicilik ve örgütsel muhalefet arasındaki karmaşık dinamiklere ışık tutarak literatüre katkı sunmaktadır.

Published: March 2024

Kripto paraların raporlanması ile ilgili uluslararası ve ulusal düzeyde kurallar henüz oluşturulma aşamasındadır. İşletmeler, bu nedenle mevcut raporlama ilkeleri üzerinden muhasebe politikaları belirleyerek, sahip oldukları kripto paraları finansal tablolarında raporlamaktadırlar. Bu çalışmanın amacı kripto paraya sahip işletmelerin bu varlıkları ile ilgili belirledikleri muhasebe politikalarının incelenmesidir. Bu yapılırken uygulamayı etkileyen boyutuyla henüz taslak aşamasında olan farklı muhasebe kuralları da incelenmiştir. İnceleme kapsamındaki işletmelerle ilgili elde edilen finansal tablolar US-GAAP veya UFRS’ye göre düzenlenmiştir. Bu nedenle, US-GAAP ve UFRS uygulamaları arasında karşılaştırma yapılarak, farklılıklar gösterilmiştir. Çalışma kapsamında Dünya’da halka açık şirket statüsünde olan 50 şirketin finansal tabloları incelenmiştir. İncelenen şirketlerde 41 tanesi sahip olduğu kripto paraları ayrı bir kalem olarak raporlamıştır. En fazla raporlama yapılan sınıflandırma ise maddi olmayan dönen varlıklar ve maddi olmayan duran varlıklar şeklinde olmuştur. Nakit akış tablosunda ise sadece 1 şirket kripto paraları finansmandan sağlanan nakit akışları kısmında raporlamıştır.
BOGOTA TURİZM KÜMESİNİN ULUSLARARASI REKABET GÜCÜNÜN ELMAS MODELİ İLE ANALİZİ
Authors: Acero Juan Camilo Fernandez , Önder Gökhan
Published: March 2024

Bu araştırmanın amacı, Kolombiya’nın başkenti Bogota’da bulunan turizm kümesinin rekabet gücünü etkileyen faktörleri incelemektir. Araştırmada öncelikle Bogota’da turizm sektörünün küme oluşturabilecek yoğunluğa sahip olup olmadığı istihdam yoğunlaşma faktöründen yararlanılarak ve turizm sektöründeki işletmelerin Bogota’daki yoğunluğu incelenerek analiz edilmiştir. Ardından Bogota turizm kümesinin rekabet gücünü etkileyen faktörler M. Porter’ın Elmas Modeli (1990) ile analiz edilmiştir. Yılda ortalama 11 milyon turist çeken kentte, gastronomi ve iş turizmi kümelerinin varlığı turizm kümesine faaliyet zenginliği sağlamaktadır. Sektörde kayıt dışılığın yüksek olması, ülkede girişimcilik seviyesinin düşük olması, yüksek yolsuzluk algısı ve yüksek vergi yükü daha rekabetçi bir turizm sektörünün oluşmasının önündeki engellerdir. Dünya çapında turizm talebindeki artış ve Kolombiya’da çatışmalara son veren barış sürecinin başlaması sektörün sahip olduğu fırsatlar olarak değerlendirilebilir.

Policy Impacts of the Department of Defense Office of Net Assessment on Sino-U.S. Soft Power Competition in Africa
Authors: Garofalo Matteo
Published: March 2024

The Strategic Consequences of Chinese Racism: A Strategic Asymmetry for the United States is a book-length academic research article written by Dr. Bradley Thayer and commissioned by Andrew Marshal, director of the Department of Defense Office of Net Assessment (ONA). Owing to both the significant policymaking power of the ONA, as well as the unique topic of the article, it is the belief of this author that Strategic Consequences is in need of examination by the international community. This paper is the first known academic investigation of Strategic Consequences and seeks to provide a critical lens of analysis. This paper examines the three most significant arguments made by Thayer and cross-examines them against existing datasets and literature to determine their relative degree of veracity. First, this paper examines Thayer’s argument that Chinese society is more racist than U.S. society, and finds that this argument is likely correct. Second, this paper examines Thayer’s argument that Chinese racism acts as a stabilizing force for the Chinese government, and finds that this argument is also likely correct. Finally, this paper examines Thayer’s argument that U.S. anti-racist culture acts as a useful tool of soft-power influence in Africa, and finds that this argument is likely incorrect.
