DRILLING MUD VACUUM GAS DEGASSER
Authors: Azad Bagirov Azad Bagirov , Mustafa Aliyev Mustafa Aliyev
Published: May 2022

Drilling mud has an important place in drilling. It is not always possible to drill all formations with water. In some cases, it is absolutely necessary to use drilling mud. Most of the time, using drilling mud provides great convenience and economy to work during drilling. For these reasons, it is very important to know the properties of drilling mud well and to use it properly.
In rotary drillings where drilling is done with fluid circulation, the continuation and uninterrupted continuation of drilling depends on providing circulation. However, some natural conditions may prevent this circulation. One of them is that it fills with gas and squirts. If the pressure of the fluids contained in the formation being drilled is high, the drilling fluid pushes back and replaces it and squirts out into the earth.
Progress with water creates great difficulties as swelling, melting, cavernous, cracked and spilled formations are drilled. Drilling mud ensures the continuity of drilling in such cases where it is inconvenient to use water due to swelling, melting, collapse and spills. While loose formations (clay, sandy, pebbly, etc.) are drilled, the water circulation loosens the natural binding materials (sand, gravel, etc.) on the well wall, causing these materials to spill into the well, compacting and eroding the tool. In such cases, it is either very difficult or impossible to lower the casing due to continuous collapse. In such a case, the most reliable method is to use drilling mud [1].

WIRE-LINE CORE DRILLING TECHNIQUE
Authors: Azad Bagirov Azad Bagirov , Ulvi Hasanov Ulvi Hasanov
Published: May 2022

Wire-line tools were first used in 1957. Today, the most used wire-line tools in core drilling work both in the world and in our country are the Q series wire-line tools. Therefore, the topics discussed in this section are based on Q-series wire-line kits.
Q-series wire-line tools were manufactured and used in three different diameters, AQ, BQ and NQ, in the first years. In the following years, HQ and PQ diameter tools started to be manufactured. The basis of the wire-line system is that there is no need to take the complete set out of the well in order to take the core obtained as a result of the drilling process out of the well.

Authors: Favretto Mario Arthur
Published: May 2022

Todo dia, milhares de animais são mortos em rodovias e diversos estudos têm registrado essas mortes anualmente. No presente estudo, percorri quase diariamente, duas vezes ao dia, um trecho de 70km de uma rodovia na região de planalto do estado de Santa Catarina, sul do Brasil, entre setembro de 2017 e maio de 2018. Foram registrados 350 atropelamentos de vertebrados, em media 2,69 vertebrados atropelados por dia, totalizando 0,02 indivíduos/km/dia. O maior valor registrado em um dia foi de 10 vertebrados atropelados. Não houve uma diferença estatisticamente significativa no número de atropelamentos diários. Esses dados indicam que as taxas de atropelamento são constantes, resultando em danos ainda maiores para a biodiversidade. Outro problema ambiental registrado foi a grande quantidade de animais domésticos atropelados, indicando uma alta taxa de abandono de animais.

Published: May 2022

Abstract The International Annual Meeting on Language Arrangements, Documentation and Publications (IAMLADP), a mechanism that brings together international organizations (IOs), is led by the United Nations and addresses such functions as the organization and management of
language services, publications and conferences. This study uses the R Project for Statistical Computing to collect and analyse the discourse patterns of job descriptions issued by IAMLADP members for their job vacancies for language professionals, including interpreters, translators, revisers,
editors and verbatim reporters. We also make recommendations regarding the interaction between IOs and universities in training qualified language professionals. Our finding was that, among the six UN official languages, English and French language skills are still most frequently required
by IAMLADP organizations. In addition, this study identifies the competencies, level of education and years of working experience most frequently required of job applicants. Therefore, it aims to provide some insights into job requirements of IAMLADP organizations, and to inspire universities
to adapt their training programs accordingly.

Published: May 2022

The article is devoted to the analysis of problems in the occurrence of difficult to predict natural emergencies. The issues related to the use of the system of automatic shutdown of gas, water and power supply at industrial enterprises and residential premises are considered. It has been established that the automatic shutdown system should have the smallest time delay. Particular attention should also be paid to autonomy and energy independence. The analysis showed that during an earthquake, a system using a “gravitational energy accumulator” can be used, which will allow obtaining the shortest time delay, and such a system does not require any additional energy consumption, special control and maintenance.

Published: May 2022

Young people represent around one-fifth of the world’s population and half of the total unemployed global workforce are the youth. In Kenya, over half of the total population is youth and a majority of them live in rural areas and are unemployed. Most rural youths engage in self-reliance projects to improve their livelihoods. This paper examines the future of rural youth agri-projects in Sub-Sahara Africa. The article is based on a study conducted to determine the effects of self-reliance projects on the livelihoods of youth in selected rural areas of Nakuru County, Kenya. Thorough surveys of youth self-reliance projects and livelihoods were conducted in Nakuru County, Kenya in 2017 by the author. The study surveyed youth who were actively undertaking self-reliance projects aimed at enhancing their livelihood. The surveys included information on the nature and type of self-reliance projects undertaken, the contribution of self-reliance projects to youth economic welfare and the challenges facing the youth and how they overcome them when undertaking the projects. The overall conclusion of this study and other related studies is that youth agri projects are having a significant contribution to their economic welfare in the rural areas, thus improving their livelihoods and hence bridging the way Agri-systems are being enhanced
A New Machine Learning Method for Bank Credit Risk Analysis
Authors: Hjouji Zaynab , M’hamdi Mohamed
Published: May 2022

We present in this article a new approach to predict the creditworthiness of borrowers that we call “Method of separating the learning set into two regions”. The goal of this approach is to build two regions from a training set. Thus, to predict the solvency of borrowers, it suffices to identify which of the two regions has its characteristic vectors; if it does not correspond to any region, credit decision-making requires further analysis. To test our approach, a large set of real and recent credit data obtained from the UCI repository is used, we trained also on a real credit database of a Moroccan bank and the creditworthiness of borrowers is analyzed at using two performance measurement indicators such as classification accuracy and AUC of the ROC curve as a robustness measurement criterion. The proposed model was compared with three traditional machine learning algorithms: LR, RBF-NN and MLP-NN. The experimental results show the superiority of the proposed approach.
A Comparison with Theory of Computation and Estimation of Pitch-Angle Diffusion Coefficients from Simulations in Noisy Reduced Magnetohydrodynamic Turbulence
Authors: Pleumpreedaporn Chanidaporn , Snodin Andrew P. , Moore Elvin J.
Published: May 2022

The transport of energetic charged particles in turbulent magnetic fields is a topic of interest in various astrophysical and laboratory plasma contexts. In order to estimate the mean free path λ∥ of a particle in the direction parallel to the mean magnetic field, one can use theoretical expressions that include the pitch-angle diffusion coefficient Dμμ. In this work we evaluate theories for Dμμ in the context of the noisy reduced magnetohydrodynamic (NRMHD) model where turbulent fluctuations are absent at large parallel wavenumbers. For most turbulence models, the standard quasilinear theory predicts zero pitch-angle diffusion only for particles with a 90◦ pitch angle, but for NRMHD a range of pitch angles is affected, leading to infinite λ∥. We examine two theories that include resonance broadening which yield finite λ∥ and compare them with test-particle computer simulations in which the parallel mean free path can be readily obtained. We find that both theories are quite accurate in some regions of the parameter space considered, but neither is particularly good when the particle Larmor radius RL becomes much smaller than the quasilinear resonance limit.
About the causes of economic degradation and measures to overcome the
Authors: Tarkhanov O
Published: May 2022

The article shows that the effect of the causes that led to the destruction of the USSR has been preserved in Russia. At the same time, it is proved that the rejection of socialism and the transition to the market only strengthens the destructive effect of these causes. It is impossible to reveal these reasons within the framework of the economic doctrines "economics" and "political economy" because of the erroneous postulates underlying them. Because of this, the forecasting method based on these exercises cannot serve to develop measures that contribute to the sustainable development of the socio-economic system. The backwardness of "economics" and "political economy" is explained by the absence in both teachings of a theoretical understanding of the practice of world (Soviet) socialism, which was facilitated by the exclusion from research of Smith's remarks about the interaction of "labor" and "nature" in the creation of food in agriculture. This fact has led to the adoption at the institutional level of an agrarian scientific and technical policy based on Liebig's erroneous doctrine of the use of mineral fertilizers, which leads to unprofitability of agriculture, a decrease in the quality and quantity of food produced, an increase in food prices, impoverishment of the population, a decrease in immunity to diseases and an increase in social tension. Institutional traps that hinder the development of the economy are identified, and measures are outlined, without which it is impossible to achieve sustainable development of the socio-economic system.
Cyberterrorism as the most important threat to the national security of the Russian Federation and its main warnings
Authors: Kobetc P.
Published: May 2022

With the incredible and powerful development of telecommunications net-works that we are witnessing in the third decade of the 21st century, international cyber-terrorism is also becoming more widespread. As a result of this phenome-non, individuals or entire international terrorist groups and organizations seek, thanks to the anonymity provided to them by cyberspace, to carry out various types of threats without any threat of identifying these criminals, their possible capture, or even physical elimination, as this happens in cases of elimination of real, not virtual, terrorist attacks. Today, international terrorist groups are increasingly using such tools to carry out attacks as DoS and DDoS attacks - denial of service, as well as other criminal methods, including phishing, online fraud, etc. Currently, international cyberterrorism poses a serious threat not only to the economy of the entire world community, but is also dangerous for various critical infrastructure facilities. In this regard, cyberterrorism has the highest level of threat to national security compared to other possible attacks by international terrorists. In this regard, the author proposes a set of measures that must be taken to prevent attacks by international cyberterrorists.

Luftverkehr: Die Sicherheit beginnt und endet immer am Boden
Authors: Konersmann Rainer
Published: May 2022

Die Anzahl der Totalverluste und Todesopfer in der zivilen Luftfahrt werden Jahr um Jahr geringer. Die Zuverlässigkeit der Triebwerke und der Avionik haben daran einen großen Anteil. Dadurch können menschliche Fehler kompensiert werden, unmöglich werden sie jedoch nicht. Denn auch außerhalb des Cockpits existieren Gefahrenquellen, die oftmals nur beim zweiten Blick erkannt werden. Bei der Auswertung von Unfallberichten kann man den Eindruck gewinnen, dass die Opferzahlen auch von der Lage eines Flugplatzes beeinflusst werden. Offensichtlich hängt dies mit der Beschaffenheit des Geländes vor und hinter einer Start- und Landebahn zusammen.

Published: May 2022

The importance of a compound that helps fight against influenza is, in times of a pandemic, self-evident. In order to produce these compounds in vast quantities, many researchers consider continuous flow reactors in chemical industry as next stepping stone for large scale production. For these reasons, the synthesis of N-acetylneuraminic acid (Neu5Ac) in a continuous fixed-bed reactor by an immobilized epimerase and aldolase was investigated in detail. The immobilized enzymes showed high stability, with half-life times > 173 days under storage conditions (6 °C in buffer) and reusability over 50 recycling steps, and were characterized regarding the reaction kinetics (initial rate) and scalability (different lab scales) in a batch reactor. The reaction kinetics were studied in a continuous flow reactor. A high-pressure circular reactor (up to 130 MPa) was applied for the investigation of changes in the position of the reaction equilibrium. By this, equilibrium conversion, selectivity, and yield were increased from 57.9% to 63.9%, 81.9% to 84.7%, and 47.5% to 54.1%, respectively. This indicates a reduction in molar volume from N-acetyl-ᴅ-glucosamine (GlcNAc) and pyruvate (Pyr) to Neu5Ac. In particular, the circular reactor showed great potential to study reactions at high pressure while allowing for easy sampling. Additionally, an increase in affinity of pyruvate towards both tested enzymes was observed when high pressure was applied, as evidenced by a decrease of KI for the epimerase and KM for the aldolase from 108 to 42 mM and 91 to 37 mM, respectively.
Integrated Governance: Achieving Governance Results and Contributing to Sector Outcomes

Published: May 2022

Achieving broad-based socio-economic development requires interventions that bridge disciplines, strategies, and stakeholders. Effective sustained progress requires more than simply an accumulation of sector projects, and poverty reduction, individual wellbeing, community development, and societal advancement do not fall neatly into sectoral categories. However, researchers and practitioners recognize key operational challenges to achieving effective integration that stem from the structures and processes associated with the current practice of international development. Integration calls for the intentional linking of intervention designs, implementation, and evaluation across sectors and disciplines to achieve mutually reinforcing outcomes. In this report, we summarize the results of a study we conducted to explore the challenges facing governance programs that integrate with sector interventions to achieve governance outcomes and contribute to sector outcomes. Through a review of policy documents and project reports from recent integrated governance programs and interviews with donor and practitioner staff, we found three integrated governance programming variants, an emphasis on citizen and government collaboration to improve service delivery, interventions that serve as the glue between sectors, and a balancing act for indicators to measure contribution to sectoral outcomes. Our analysis identified four key success factors: contextual readiness, the application of learning and adapting approaches, donor support, and recognition of the limitations of integrated governance. We then discuss recommendations and implications and for answering the challenge of integrating governance and sector programming to achieve development outcomes.

The article presents the results of research on the creation of drill bits with high durability and sufficient productivity when drilling hard rocks. Four areas of research have been identified to solve this problem: the crown must be multilayer, the profile of the diamond-bearing layers must represent annular conical protrusions and cavities; diamond layers should be separated by diamond-free layers of lower hardness and experience uniform specific pressure during operation; the design of the bit should take into account the peculiarities of the rock destruction mechanism under the action of diamond grains; the manufacturing technology of the crown matrix must be perfect. Only defect-free diamonds obtained by sorting with special methods are involved in the creation of the matrix; Adding CrB2 or VN nanopowders to the composition of the charge makes it possible to improve the quality of the matrix structure, all tribiological and operational properties, and due to the preliminary metallization of high-strength synthetic diamonds, a transition zone “diamond-coating-matrix material” is created, which will significantly increase the wear resistance of diamond rock cutting tools. The mentioned problems have been partially solved: a multilayer impregnated bit with a ridged profile of diamond-bearing layers and a uniform specific pressure on the latter during drilling has been created and put into production, laboratory studies have been carried out to improve the quality of composite materials with positive results, further research is being carried out in all other areas.

The current stage of development of the oil industry of Kazakhstan is characterized by its entry into the stage of declining production. Many large deposits are characterized by a rapid increase in product wetting. An unfavorable geological and technological structure of oil reserves has been formed at the oilfield, where the share of traditional (technologically developed) reserves is only 35%. At the same time, the share of hard-to-extract oil reserves (low-permeable layers, residual reserves, deeply loaded horizons, high-viscosity oil, gas subsurface areas) is 2/3 or 65%. Based on the estimates given in this paper, it is proposed to consider the development of low- permeable layers and residual oil resources as priority areas for the development of hard-toextract oil reserves. Their successful development will ensure the effective development of about half of the industrial oil reserves. Increasing the efficiency of development of low-permeable layers will attract several billion tons of industrial oil reserves for development.

An approach based on deep learning for automatic colorization of image with optional userguided hints. The system maps a grey-scale image, along with, user hints” (selected colors) to an output colorization with a Convolution Neural Network (CNN). Previous approaches have relied heavily on user input which results in non-real-time desaturated outputs. The network takes user edits by fusing low-level information of source with high-level information, learned from large-scale data. Some networks are trained on a large data set to eliminate this dependency. The image colorization systems find their applications in astronomical photography, CCTV footage, electron microscopy, etc. The various approaches combine color data from large data sets and user inputs provide a model for accurate and efficient colorization of grey-scale images. Keywords—image colorization; deep learning; convolutional neural network; image processing.
An Intelligent Process Fault Diagnosis System based on Andrews Plot and Convolutional Neural Network
Authors: Wang Shengkai , Zhang Jie
Published: May 2022

This paper proposes an intelligent process fault diagnosis system based on the techniques of Andrews plot and convolutional neural network. The proposed fault diagnosis method extracts features from the on-line process measurements using Andrews function. To address the uncertainty of setting the proper dimension of extracted features in Andrews function, a convolutional neural network is used to further extract diagnostic information from the Andrews function outputs. The outputs of the convolutional neural network are then fed to a single hidden layer neural network to obtain the final fault diagnosis result. The proposed fault diagnosis system is compared with a conventional neural network based fault diagnosis system. Applications to a simulated CSTR process show that the proposed fault diagnosis system gives much better performance than the conventional neural network based fault diagnosis system. It reveals that the use of Andrews function and convolutional neural network can improve the diagnosis performance.

Some positive answers to the problem of endowing a dynamical system with a Hamiltonian formulation are presented within the class of Poisson structures in a geometric framework. We address this problem on orientable manifolds and by using decomposable Poisson structures. In the first case, the existence of a Hamiltonian formulation is ensured under the vanishing of some topological obstructions, improving a result of Gao. In the second case, we apply a variant of the Hojman construction to solve the problem for vector fields admitting a transversally invariant metric and, in particular, for infinitesimal generators of proper actions. Finally, we also consider the hamiltonization problem for Lie group actions and give solutions in the particular case in which the acting Lie group is a low-dimensional torus.

This article assesses the eighth goal of sustainable development – Decent work and economic growth (SDG8). The theoretical part of the article analyses the concept of SDG8 and its importance for the European Union’s economy. The research methodology covers multiple criteria decision-making (MCDM) approaches. In order to assign the weight to criteria, the CRITIC method was employed. After that, the priority line was developed by applying the COPRAS approach. CRITIC method results showed that assessing the targets and their constituting indicators of the SDG8, the most vital indicator is the annual growth rate of real GDP per employed person. COPRAS method results showed that the most advanced countries to implement SDG8 are Germany with 100 points and France with 91 points. The results also revealed that the less advanced in implementing SDG 8 countries are Latvia with 59 points and Finland with 56 points.
Photodissociation Rate, Excess Energy, and Kinetic Total Energy Release for the Photolysis of H2O Producing O(1S) by Solar UV Radiation Field
Authors: Kawakita Hideyo
Published: May 2022

Forbidden atomic oxygen lines in emission are ubiquitous for cometary spectra in the visible region, and the oxygen atoms in metastable states causing the forbidden emission lines are considered as a proxy of H2O in coma. However, the photodissociation rate and related quantities for the dissociation reaction producing O(1S) from H2O have never been estimated based on experimental studies. Based on the recent laboratory study of the photodissociation reaction of H2O producing O(1S) by Chang et al., we derived the photodissociation rates of the reactions for both the O(1S) and O(1D) channels, consistent with the green-to-red line ratios observed in comets so far. Furthermore, the total kinetic energies released for the photodissociation products are also consistent with the intrinsic line widths of forbidden atomic oxygen emission lines observed in comets. The photodissociation rates of H2O leading to O(1S) and O(1D) calculated here do not significantly change the previous estimates of CO2/H2O in comets based on the green-to-red line ratios of the comets if we use the photodissociation rates of CO2 (calculated elsewhere) with a correction for the difference of solar UV spectra used for calculating photodissociation rates of H2O and CO2.
Inflated Eccentric Migration of Evolving Gas Giants I – Accelerated Formation and Destruction of Hot and Warm Jupiters
Authors: Rozner Mor , Glanz Hila , Perets Hagai B. , Grishin Evgeni
Published: May 2022

Hot and warm Jupiters (HJs and WJs, correspondingly) are gas giants orbiting their host stars at very short orbital periods (P
HJ < 10 days; 10 < P
WJ < 200 days). HJs and a significant fraction of WJs are thought to have migrated from initially farther-out birth locations. While such migration processes have been extensively studied, the thermal evolution of gas giants and its coupling with migration processes are usually overlooked. In particular, gas giants end their core accretion phase with large radii, then contract slowly to their final radii. Moreover, intensive heating can slow the contraction at various evolutionary stages. The initial large inflated radii lead to faster tidal migration, due to the strong dependence of tides on the radius. Here, we explore this accelerated migration channel, which we term inflated eccentric migration, using a semi-analytical, self-consistent model of the thermal–dynamical evolution of the migrating gas giants, later validated by our numerical model (see the companion paper, paper II). We demonstrate our model for specific examples and carry out a population synthesis study. Our results provide a general picture of the properties of the formed HJs and WJs via inflated migration, and their dependence on the initial parameters/distributions. We show that the tidal migration of gas giants could occur much more rapidly then previously thought, and could lead to the accelerated destruction and formation of HJs and an enhanced formation rate for WJs. Accounting for the coupled thermal–dynamical evolution is therefore critical to understanding the formation of HJs/WJs, and the evolution and final properties of the population, and it plays a key role in their migration processes.

We have selected six sources (G209.55–19.68S2, G205.46–14.56S1-A, G203.21–11.20W2, G191.90–11.21S, G205.46–14.56S3, and G206.93–16.61W2) from the Atacama Large Millimeter/submillimeter Array Survey of Orion Planck Galactic Cold Clumps (ALMASOP), in which these sources have been mapped in the CO (J = 2−1), SiO (J = 5−4), and C18O (J = 2−1) lines. These sources have high-velocity SiO jets surrounded by low-velocity CO outflows. The SiO jets consist of a chain of knots. These knots have been thought to be produced by semiperiodic variations in jet velocity. Therefore, we adopt a shock-forming model, which uses such variations to estimate the inclination angle and velocity of the jets. We also derive the inclination angle of the CO outflows using the wide-angle wind-driven shell model and find it to be broadly consistent with that of the associated SiO jets. In addition, we apply this shock-forming model to another three protostellar sources with SiO jets in the literature—HH 211, HH 212, and L1448C(N)—and find that their inclination angle and jet velocity are consistent with those previously estimated from proper-motion and radial-velocity studies.

Complex organic molecules (COMs) can be produced efficiently in ice mixtures that simulate the ice mantle on cosmic dust grains, according to prior experimental studies. However, the mechanism that brings the reactive species together in the ice has been debated. Thermal diffusion, which is widely regarded as the main mechanism to bring reactants together, is inefficient at a typical dense cloud temperature of 10 K. A recent experimental study found that the transition of a thin CO ice film from the amorphous to crystalline phase happens at about 10 K. When a small fraction of CO2 was mixed with CO, the CO2 molecules can separate and form clusters during CO phase transition. It was further proposed that the separation of minor species in the CO ice during phase transition may be an important mechanism to form interstellar COMs without the need for thermal diffusion. In this study, we try to verify this new mechanism through laboratory experiments. An ice mixture of CH3OH and CO, which is an analog of the outer layer of the ice mantle on cosmic dust grains, was exposed to UV irradiation to produce radicals such as HCO and CH2OH, whose concentration was monitored during the subsequent warm-up of the ice. We find clear evidence that during the CO phase transition, most of the radicals recombine to form other molecular species, therefore supporting the recently proposed mechanism of COM formation via CO phase transition.

Purpose: To investigate the role of pre- and post-stereotactic body radiation therapy (SBRT) neutrophil-to-lymphocyte ratio (NLR) in patients with localized pancreatic cancer treated with anti-PD-1 (programmed cell death protein-1) antibody and SBRT.Materials and Methods: This was a retrospective review of 68 patients with borderline resectable or locally advanced pancreatic cancer treated with anti-PD-1 antibody and SBRT after multi-agent chemotherapy. Immunotherapy was administered with 5-fraction SBRT in the neoadjuvant, concurrent, or adjuvant/maintenance setting. Clinical outcomes included overall survival (OS), local progression-free survival, distant metastasis-free survival, and progression-free survival. Median pre- and post-SBRT peripheral blood markers were compared with the Mann-Whitney U test. Univariate and multivariable analyses (UVA and MVA) were performed to identify variables associated with clinical outcomes. Linear regression was performed to determine correlations between variables and peripheral blood markers. Results: A total of 68 patients were included in the study. The percent change between median pre- and post-SBRT absolute lymphocyte count (ALC), absolute neutrophil count, and NLR were -36.0% (p < 0.001), -5.6% (p = 0.190), and +35.7% (p = 0.003), respectively. Median OS after SBRT was 22.4 months. On UVA, pre-SBRT CA19-9 (hazard ratio [HR] = 1.001; 95% confidence interval [CI], 1.000–1.001; p = 0.031), post-SBRT ALC (HR = 0.33; 95% CI, 0.11–0.91; p = 0.031), and post-SBRT NLR (HR = 1.13; 95% CI, 1.04–1.22; p = 0.009) were associated with OS. On MVA, induction chemotherapy duration (HR = 0.75; 95% CI, 0.57–0.99; p = 0.048) and post-SBRT NLR (HR = 1.14; 95% CI, 1.04–1.23; p = 0.002) predicted for OS. Patients with post-SBRT NLR ≥3.2 had a median OS of 15.6 months versus 27.6 months in patients with post-SBRT NLR <3.2 (p = 0.009). On MVA linear regression, log10CTV had a negative correlation with post-SBRT ALC (regression coefficient = -0.314; 95% CI, -0.626 to -0.003; p = 0.048). Conclusion: Elevated NLR after SBRT is primarily due to depletion of lymphocytes and associated with worse survival outcomes in localized pancreatic cancer treated with anti-PD-1 antibody. Larger CTVs were associated with decreased post-SBRT ALC.

Erdheim-Chester disease (ECD) is a rare non-Langerhans cell histiocytosis typically featuring lower extremity osteosclerosis (96%) from Langerin-negative histiocytes with fibrosis. Central nervous system (CNS)-only disease is extremely rare, and particularly difficult to diagnose and manage. Neurologic complaints may be refractory to systemic therapy (ST), and the role of radiation therapy (RT) is undefined. We present a patient with ECD of the medulla complicated by respiratory failure and strength deficits with disseminated leptomeningeal disease (LMD) but not systemic disease, representing the first report of CNS-limited ECD with LMD. He received upfront craniospinal irradiation (CSI), representing a rare account of CSI for ESD, with marked clinical improvement resulting in extubation and improved strength. CSI facilitated excellent preservation of quality of life, and no treatment-related toxicity was observed prior to eventual, unrelated cardiopulmonary arrest. Thus, palliative CSI may augment ST by safely offering improved local control and symptomatic relief for CNS ECD.
Phylogeny, infrageneric classification and historical biogeography of Mesochila Rivalier, 1969 (Coleoptera: Cicindelidae), with the performance of different phylogenetic inferences using morphological data compared

In this study, we aim to understand the boundaries and the species evolutionary relationships in Mesochila, which includes 20 species arranged into three subgenera. We also conducted a biogeographic analysis that allowed us to identify the major events that shaped the currently disjunct distribution of the group. Our analyses were performed employing four major phylogenetic algorithms: equal and implied weight parsimony, maximum likelihood and Bayesian inference. Phylogenetic analyses, including 25 taxa (all 20 species in the genus plus five outgroups) and 37 characters, indicated that Mesochila is a monophyletic group composed of four strongly supported lineages, although no consensus was attained regarding relationships between lineages. Bayesian inference resulted in the less resolved topology, whereas implied weight parsimony yielded the most different tree when using a low k value (1). We present a new infrageneric classification for the group with the description of Mesochila (Neomesochila)subgen. nov. to accommodate M. (N.) brevipennis, M. (N.) drechseli, M. (N.) moraveci, and M. (N.) prepusula. Furthermore, we transfer M. (M.) distincta from M. (Eumesochila) back to M. (Mesochila). The biogeographical analysis suggested a South American origin for the group, in Chacoan/Paraná dominions (Atlantic rainforest/Cerrado biomes), with subsequent dispersions to Central America and Amazonia.

A new Australasian genus in the orb-weaving spider family Araneidae Clerck, 1757 is described to include seven species:Salsa fuliginata(L. Koch, 1871)comb. nov.(type species; =Epeira rubicundulaKeyserling, 1887)syn. nov.) (Australia, introduced to New Zealand);S. brisbanae(L. Koch, 1867)comb. nov.(Australia);S. canalae(Berland, 1924)comb. nov.(New Caledonia);S. nenebasp. nov.(Papua New Guinea);S. recherchensis(Main, 1954)comb. nov.(Australia);S. ruedasp. nov.(Australia); andS. tartarasp. nov.(Australia; Lord Howe Island endemic).Salsagen. nov.belongs to the Australasian informal backobourkiine clade and differs from other genera of this clade by a distinct abdominal shape (single posterior abdominal tubercle) and ventral colouration (pale lateral spindle-shaped bands), male pedipalp morphology (C-shaped median apophysis that has teeth-like tubercles inside the basal arch) and the shape of the female epigyne scape (partially translucent and generally shorter than the epigyne plate). Based mainly on male pedipalp morphology within the backobourkiines,Salsagen. nov.has closest morphological affinities withAcroaspisKarsch, 1878 andSoccaFramenau, Castanheira & Vink, 2022.
Donner à voir ce qui resterait invisible autrement
Authors: Richter Alexandra
Published: May 2022

Résumé Comme Wittgenstein, Walter Benjamin s’inspire pour ses travaux de la morphologie goethéenne en tant que sciences des formes de la vie. Pour son livre sur Paris, capitale du XIXe siècle, Benjamin affirme avoir transposé le concept goethéen de phénomène primitif « du domaine de la nature au domaine de l’histoire ». Ce transfert s’accompagne chez lui d’une critique de l’ontologisation du concept de « nature ». Or les travaux philosophiques de Benjamin sur les villes seront à leur tour contestés (par Adorno mais aussi Derrida) pour avoir ontologisé le concept d’« histoire » en se contentant d’une simple description des phénomènes, faisant fi de tout jugement. La discussion montre déjà les arguments de fond que l’on retrouve dans le débat actuel d’une possible critique des formes de vie.
