Published: July 2021

The article discusses the possibility of using pulsed laser ablation of nanosecond duration to modify the surface of a cutting tool after regrinding and restoration. Experimental studies of the resistance characteristics of cutting tools with modified surfaces via laser ablation in air and in liquid have been carried out. It was found that after modifying the surface of cutting plates via laser ablation in air, the wear on the trailing surface of the cutting tool at a processing speed of V = 50 m/min is 8 times less than that of the untreated one, the build-up is 20 times less. The wear of the trailing surface of the plates at V = 70 m/min is 2 times less than that of the untreated sample. The resistance studies show surface modification of the cutting tool increases the tool life of the remanufactured tool, overall tool life and savings in tool costs.

Authors: Akimova Olga V. , Tereshina Irina S. , Kaminskaya Tatiana , Karateev Igor A.
Published: July 2021

Atomic force microscopy (АFМ) and high-precision scanning electron microscopy methods were used to study the surface of diffusion filter-membranes of alloy Pd93Y7. The formation of alterations in structure in one of membranes was established as a result from the homogenizing annealing at 900°C for 1 hours. It was found that the reversible doping of the membrane alloy with hydrogen caused the dispersion of the diffusion filter-membranes’ surface structure. Differences in changes by the surface structure are determined during the hydrogenation in directional and non-directional flow of hydrogen.

Authors: Shatagin Dmitrii A. , Anosov Maksim S. , Kolchin Pavel , Ryabov Dmitry A. , Kiselev Andrey V.
Published: July 2021

The article discusses the mechanical properties and cold resistance of austenitic stainless steel (analogue 07Cr25Ni13) obtained by 3D printing by electric arc surfacing from ER309LSI welding wire on a CNC machine. These properties were investigated in the process of physical tests of samples cut along and across the layers of 3D printing for tensile and impact bending. Using optical microscopy, the microstructures of steel sections were obtained for various temperature conditions of interlayer exposure, as well as the values ​​of the recommended microhardness. In the process of 3D printing, an intelligent system for monitoring the dynamic stability of the electric arc was applied, which made it possible to guarantee the stability of the structure and properties of the obtained samples throughout the entire process of surfacing. Additional heat treatment of experimental samples (austenitization) was considered as a way to improve mechanical properties and cold resistance. It has been established that the dynamic stability of an electric arc, modes of interlayer temperature holding and subsequent heat treatment largely determine the mechanical properties and cold resistance of ER309LSI steel obtained by 3D printing by electric arc surfacing.

Authors: Yadav Mayank , Singh Sumit Pratap , Haseen Mohd Azam , Yadav Renu , Beg Mohammed Haneef
Published: July 2021

Introduction:

Brachiobasilic arteriovenous fistula although little complex to create provides a suitable alternative to radiocephalic and brachiocephalic fistula, due to its autogenous nature and protective deep-seated anatomy of basilic vein. The purpose of this study was to evaluate the outcome among various techniques of brachiobasilic fistula (BBF) in terms of patency and complication rates.

Methods:

We retrospectively identified 50 patients in which BBFs were constructed between January 2015 and January 2018. The basilic vein was transposed in 16 patients and elevated in 34 patients: 14 as a single-stage technique and 20 with a two-stage (delayed elevation) technique.

Results:

The mean age of patients in this study was 50.8 years, with 72% of them having diabetes mellitus. There was no significant difference in the primary and secondary patencies among various techniques at 6, 12, 18, and 24 months. Neither there was any significant difference found in the complication rates between different techniques used to create BBF. The overall primary patency rates are 78% and 60% and secondary patency rates are 82% and 68% at 1 and 2 years, respectively.

Conclusion:

BBF can be considered as a true alternative before prosthetic grafts in patients with exhaustive cephalic veins.
Homocysteinemia-Induced Upper-Extremity Deep-Vein Thrombosis
Authors: Sud Saurabh , Kumar Yogesh , Bhardwaj Saurabh , Dwivedi Deepak
Published: July 2021

Hyperhomocysteinemia is a rare condition which predisposes to arterial and venous thrombosis. Plasma homocysteine levels are influenced by many genetic factors and environmental factors. Increased levels of homocysteine at high-altitude areas (HAA) can predispose to upper-extremity deep-vein thrombosis (UEDVT). Therefore, awareness by the medical authorities regarding this entity at HAA as a sole cause of UEDVT needs to be established. Prompt reduction in the homocysteine level can be therapeutic as well as prophylactic in preventing the morbidity.

Published: July 2021

Pseudoaneurysm is a rare long-term complication following coarctation of aorta repair. Thoracic endovascular aortic repair is the most common approach. However, under some circumstances, this cannot be performed. Therefore, the traditional open approach is indicated. Although the potential ischemia of spinal cord is related to this approach, it remains an efficient alternative. The authors report a case of late pseudoaneurysm of the distal aortic arch following coarctation of aorta repair in a 26-year-old male that has been successfully repaired by left thoracotomy.
Palmar and plantar fibromatosis: a review
Authors: Stewart Brian D. , Nascimento Alessandra F.
Published: July 2021

Palmar fibromatosis (Dupuytren disease/contracture) is the most common type of fibromatosis, defined as a benign proliferation of fibroblasts and myofibroblasts. The disease process is most common in white, middle-aged and older men occurring at the distal palmar crease leading to nodules and contracture, which in many cases recur after surgical treatment. In a similar process, plantar fibromatosis (Ledderhose disease) is a proliferation of fibroblasts and myofibroblasts on the plantar aponeurosis of mostly middle-aged patients that may lead to painful nodules but usually does not lead to contracture. Both processes are histologically similar, composed of a bland cellular proliferation of spindle cells with a bluish appearance and with a variable amount of background collagen, depending on the age of the lesion. The etiology of both lesions is still uncertain, while treatment ranges from observation to surgery, with some pharmacologic agents being investigated with mixed success. In this paper we provide an overview of both processes with regards to clinical and radiologic findings, pathophysiology, diagnosis, treatment, and prognosis.

Authors: Giotakis A.I. , Karow E.M. , Scheithauer M.O. , Weber R. , Riechelmann H.
Published: July 2021

Background: Chronic rhinosinusitis (CRS) is a common health problem. If medical treatment fails, endonasal sinus surgery is a valuable treatment option. A thorough postsurgical treatment is needed including, among others, nasal saline irrigations (NSI). In this prospective, controlled, single blinded, randomized trial, we aimed to evaluate efficacy of nasal saline irrigations following endonasal sinus surgery in CRS-patients with nasal polyps. Methodology: We examined patient's nasal symptoms, general quality of life and postoperative condition of the mucosa. We also investigated whether or not NSI reduced the number of missed workdays after surgery (MWD). Patients were randomized into an irrigation and non-irrigation arm. Results: Following treatment, mean nasal sum-score in the irrigation arm was 4.4 and in the non-irrigation arm it was 6.3. Accordingly, mean general sum-score in the irrigation arm was 2.5 and in the non-irrigation arm 4.8. Thus, nasal irrigation led to a more pronounced improvement of nasal and general symptoms than in the non-irrigation arm. No differences were observed in postoperative condition of mucosa or number of MWD. Conclusions: Nasal irrigation improves symptoms score after ESS in patients with CRSwNP.

Published: July 2021

Background: Calcium plays an integral role in olfactory signal transduction, including feedback inhibition. Sodium citrate acts as a calcium sequestrant and when applied intranasally, reduces free calcium available for feedback inhibition, which should theoretically improve olfaction. We aimed to investigate the utility of intranasal sodium citrate in improving the olfactory function of hyposmic patients, by performing this prospective placebo controlled, single-blind trial. Methodology: Monorhinal olfactory testing for odour identification and threshold was performed in hyposmic patients using Sniffin Sticks, before and after treatment. Treatment consisted of one-off sodium citrate solution application to the olfactory cleft. Sodium chloride solution was applied to the contralateral olfactory cleft, which therefore acted as placebo control. Patients were blinded to the side of sodium citrate application, and side of treatment was randomized between patients. Results: 57 patients participated, aged 22-79. Causes of hyposmia included: post-viral (7); posttraumatic (10); sinonasal disease (30) and idiopathic (10). Compared with placebo, there was significant improvement in the identification scores of participants with post-viral hyposmia, following sodium citrate treatment. No significant change in olfactory function occurred for either identification or threshold in any other aetiological subgroup. Conclusions: Intranasal sodium citrate may be of benefit to patients with post-viral hyposmia.

Published: July 2021

Visceral leishmaniasis (VL) is the most severe clinical form of the disease and has been reported in the Jazan region of southwest Saudi Arabia. This study aimed to diagnose VL by real-time polymerase chain reaction (PCR) and the direct agglutination test (DAT) and to identify the causative Leishmania species. A total of 80 participants, including 30 suspected VL patients, 30 healthy endemic control individuals, and 20 malaria disease controls, were enrolled in this study. Blood samples were collected and tested for Leishmania DNA by real-time PCR and for antibody by the DAT. Sequencing of some amplified PCR products was used to identify the causative Leishmania species. The diagnosis of VL was successfully achieved by both real-time PCR and by DAT with 100% sensitivity. Leishmania donovani and Leishmania infantum species were detected by sequencing both by the kDNA and ITS1 target genes, followed a BLASTn search. The detection of VL antibody by the DAT followed by the confirmatory detection of Leishmania DNA in patient blood by PCR could promote the adoption of the much less invasive and more sensitive methods for the routine diagnosis of VL. Further study with high sample volume to evaluate the PCR and the DAT are needed, to generate more robust evidence. Based on the sequencing results, emerging studies on VL should focus on the causative Leishmania species, reservoirs, and vectors that are important in the study area.
Household Disinfection Interventions to Prevent Cholera Transmission: Facilitators, Barriers, Training, and Evidence Needs
Authors: Heylen Camille , Ali Cawo , Gallandat Karin , Lantagne Daniele , String Gabrielle
Published: July 2021

There are two common household disinfection interventions to prevent interhousehold transmission of cholera: household spraying, whereby a team disinfects cholera patients’ households, and household disinfection kits (HDKs), whereby cleaning materials are provided to cholera patients’ family members. Currently, both interventions lack evidence, and international agencies recommend HDK distribution; however, household spraying remains widely implemented. To understand this disconnect, we conducted 14 key informant interviews with international and national responders and a study in Haiti assessing HDK efficacy using two training modules including 20 household surveys and 327 surfaces samples before and after cleaning. During interviews, 80% of the international-level informants discussed evidence gaps for both interventions, and 60% preferred HDKs. Conversely, no national-level informants knew what an HDK was; therefore, they all preferred spraying. Informants discussed behavior changes, bleach perceptions, and implementation as facilitators and/or barriers to implementing both interventions. In households, training with demonstrations regarding the use of HDK led to increased reductions of Escherichia coli (P < 0.001) and Vibrio spp. (P < 0.001) on surfaces after participants cleaned the household compared with a hygiene promotion session only. These results emphasize the gap between the current international-level policy and the realities of cholera response programs, highlight the need for evidence to align household disinfection recommendations, and underscore the importance of the dissemination and training of responders and affected populations regarding methods to prevent intrahousehold cholera transmission.

Published: July 2021

Začetki Zgodovinarskega indeksa citiranja segajo v leto 2003, ko so raziskovalci Inštituta za novejšo zgodovino začeli spremljati in sistematično popisovati citate za prijave projektov in programov na ARRS. Citatni indeks je doživel nekaj nadgradenj, poskusov harmonizacije podatkov in prečiščevanja relacijskih baz, vendar je bilo v zadnjih letih ugotovljeno, da sistem ne zadostuje potrebam indeksatorjev in uporabnikov. Pred nadgradnjo smo izvedli analizo podatkov, kjer so se identificirale največje težave. Nadgradnja je potekala v dveh delih; v prvem delu smo nadgradili administrativni del, v drugem delu pa spletno aplikacijo. Zgodovinarski indeks citiranja je bil med nadgradnjo tehnično posodobljen in s tem oblikovan tako, da je intuitiven za indeksatorje in uporabnike.

Na področju govornih in jezikovnih tehnologij predstavlja avtomatsko razpoznavanje govora enega izmed ključnih gradnikov. V prispevku bomo predstavili razvoj avtomatskega razpoznavalnika slovenskega govora za domeno dnevnoinformativnih oddaj. Arhitektura sistema je zasnovana na globokih nevronskih mrežah. Pri tem smo ob upoštevanju razpoložljivih govornih virov izvedli modeliranje z različnimi aktivacijskimi funkcijami. V postopku razvoja razpoznavalnika govora smo preverili tudi, kakšen je vpliv izgubnih govornih kodekov na rezultate razpoznavanja govora. Za učenje razpoznavalnika govora smo uporabili bazi UMB BNSI Broadcast News in IETK-TV. Skupni obseg govornih posnetkov je znašal 66 ur. Vzporedno z globokimi nevronskimi mrežami smo povečali slovar razpoznavanja govora, ki je tako znašal 250.000 besed. Na ta način smo znižali delež besed izven slovarja na 1,33 %. Z razpoznavanjem govora na testni množici smo dosegli najboljšo stopnjo napačno razpoznanih besed (WER) 15,17 %. Med procesom vrednotenja rezultatov smo izvedli tudi podrobnejšo analizo napak razpoznavanja govora na osnovi lem in F-razredov, ki v določeni meri pokažejo na zahtevnost slovenskega jezika za takšne scenarije uporabe tehnologije.
Zarządzanie posthumanistyczne
Authors: Pałasz Michał
Published: July 2021

Posthumanistic management The article introduces the concept of posthumanistic management as a result of exploring the relationships between the Anthropocene, management and contemporary humanities. Posthumanistic management is a response to the pressing need of management reform in the context of a swirl of crises of what is called Generalized Anthropocene (and described as brutal adulthood of humanity), especially concerning the anthropogenic climate-ecological and derivative crises. The author argues that the culture of management (dominant activity of the modern world) based on greed is the reason to make management at least co-responsible for the crises of the Anthropocene next to the pathological actions and inactions of business and political actors and the dominant socio-economic system of capitalism itself. The text summarizes the attempts to humanize management (business ethics, corporate social responsibility, stakeholder theory, sustainable development, critical management studies, humanistic management) and makes an effort of posthumanistic correction of one of the dominant definitions of economic management. A posthumanistic correction of management is based on assigning agency and dignity to all, also non-human resources of management processes, and on transformation of the purpose of organizational practices from focused on particular goals of the organization towards the pursuit of the heterogeneous common good. The posthumanization of management implies, the author argues, pansolidarity, radical empathy, the fall of the mean-end dualism, redistansation and cyclization. The article ends by highliting some of the flaws of the introduced concept and some possible ways of overcoming them.

Management in the Anthropocene and What Comes Out of It. Analysis of the Literature on the Entanglement of Phenomena
The Anthropocene is a term that not only conjures up all kinds of images in the mind but provides an impulse to reconsider the scope of human responsibility for man-triggered processes and its place in the system of related factors on our planet. At the same time, it is a term treated by many with ambivalence, reluctance, and caution, as it often harbingers the imminent environmental doom, the awareness of which may change the current balance of political and economic forces. Additionally, it is still involved in emphasizing the central role of the human, it is sometimes romanticized and can lead to an aestheticization of the climate catastrophe instead of taking actions resulting not from the will of heroism, but from humility. The ongoing debate on the Anthropocene in the field of management studies is of extraordinary importance, because it provides a framework for undertaking any activity – the activity which either aggravates or alleviates the negative environmental impact. The purpose of this paper is to discuss the contexts in which the scientific literature in the field of management talks about the Anthropocene and to explore the level of gravity that is assigned to management in this conventional geological and cultural era. Particular attention is paid to the dominant trends of reflection which illustrate a wide variety of attitudes towards the Anthropocene, including the one that places the Anthropocene against the background of efforts to maintain the status quo and the one that perceives it as a prelude to concocting alternative or even anarchist visions of management. The paper focuses on theoretical voices, which determined the method of analysis based on the study of language and the interpretation of narratives and metaphors.
(Post)humanistyka antropocentrycznego exodusu – w stronę roślinnego socjetas
Authors: Dziadek Martyna
Published: July 2021

(Post)humanities of the Anthropocentric Exodus: Towards plant societas The main aim of this article is an attempt at mapping the preventive strategy in the epoch of climate and ecology crisis through the lens of (post)humanities. Drawing upon posthuman perspectives, as well as methodologies and research tools, I will try to grasp the complexity of reality through relational ontologies, which linked Anthropos with the plant kingdom. As Małgorzata Praczyk pointed out, posthumanism is still not so investigated in humanities (especially in the historic field), and even when it finally appears, ended up at counterproductive reductionism. Trying to avoid this impasse, the author of this text is using the method of morphing history which allows changing the perspectives from anthropocentric one to the plants, thus polyphonic assemblages (A. Tsing) enables to re(present) the other and multispecies agency. Finally, I will map the possible perspectives in an epoch of Anthropocene according to the statement: “the environmental crisis brings a crisis of imagination”(L. Buell). In that sense, rethinking humanities with indigenous knowledge(s) is strongly needed as well as “deep adaptation” (J. Bendell) in order to understand that “humans interact not only with each other, but in all times, places and context of ecosystems, and are affected by them” (R.C. Foltz).
Niepełnosprawczość. Antropocen i modernistyczne sny
Authors: Krassowski Marcin
Published: July 2021

Not-quite-agency. Anthropocene and Modernist Dreams The article deals with the issue of tension between management and unplanned consequences that result from it. By recalling the works of Anna Tsing, I indicate that management based on the modernist rationality led to the Anthropocene defined as the era of feral effects. The full agency of man, which is at the basis of modernist thinking about human-environment relations, is presented in the article as a myth. In fact, the actions leading to the Anthropocene were of the nature of not-quite-agency – their consequences were beyond the domain of human control. The article also deals with the issues of management in the Anthropocene itself, pointing out that global attempts to overcome the environmental crisis are also marked by not-quite-agency, which – in order to protect against possible negative side effects – requires inclusion in the design process by thinking about the internal resilience of the system.

Bauer Publisher – Traditional Publisher in the Digital World

The Bauer publishing house has gained the position of the largest press publisher in Poland thanks to the creation of an extensive portfolio of magazines aimed at various groups of recipients. The pub­lishing strategy based on a low copy price and efficient marketing ensured high sales revenues and relatively high independence from advertising revenues. Despite the decline in the readership of the printed press, the publishing house did not make any efforts to digitally transform its magazines and develop its activities on the Internet. Only in the face of the coronavirus pandemic, it created e-edi­tions and websites of a few titles. However, the recent business decisions of the German owner in­dicate that instead of investing in digital change and waiting for its effects, it is more willing to quit the traditional media markets.

Institution of an expert in criminal and civil proceedings – similarities and differences
An expert in both criminal and civil proceedings is a qualified assistant of the court (or other procedural bodies) providing special evidentiary information. The opinion issued by him is an independent source of evidence of specific importance. Contrary to a witness, they are not providers of information about facts, but interpreters of these facts from a scientific and technical point of view. They must possess specialized knowledge and experience otherwise unavailable to other participants in the proceedings. The role and function of experts in criminal and civil proceedings are seemingly similar. However, each of these proceedings has many special regulations that cause significant differences in this respect. These differences are the focus of this study.

The issue of obtaining access to official notes of police officers in order to use them as evidence in a civil trial
The problem of obtaining access to official notes of police officers is an important practical issue, particularly in a situation where there is a need to use these documents in a civil trial. Such a document may constitute essential means of evidence in a civil trial, confirming the facts presented by a party to the proceedings. In practice, however, police officers do not always automatically provide access to the documents in question at the request of a party; therefore, the purpose of this article is to analyze the provisions under which a party may request access to such documents. The article examines the standpoint of the judicature, which indicates whether police officers are obliged to provide access to such documents to a party or third parties and whether such an action is consistent with the provisions of the GDPR as regards the protection of personal data.

The Quality of Vital Registration of the Jews in East-Central Europe in the Nineteenth Century
Authors: Jankowski Tomasz M.
Published: July 2021

Vital records are one of the main sources providing insight into the demographic past. For most of the nineteenth century, however, the degree of under-registration of vital events among Jews was much higher than among non-Jews. These omissions undermine the credibility of demographic data on fertility and mortality published in contemporary statistical yearbooks. The analysis shows that the male-to-female ratio at birth aggregated on a regional level reveals the highest under-registration among Jews in the Russian Empire, including Congress Poland, until World War I. On the other hand, Prussian registration covers the Jewish population most completely and already in the 1820s shows no signs of under-registration. Despite the general low quality of registration systems, records from selected individual towns still pass quality tests. Top-down imposition of the registration duties, corporatism, defective legal regulations, bureaucratic inefficiency and personal characteristics of civil registrars were the main reasons for under-registration.

Development of Non-Woven Fabrics from Bamboo/Polypropylene Fibres
and its Application in Personal Protective Equipment-A Review.
Authors: Kanchana Devi  , Rajkumar G
Published: July 2021

The important component of personal protective equipment is a mask.
Mask is more important in a pandemic because it safeguards our life by stopping
the spreading of the Coronavirus by entrapping the droplets from the corona
affected person to enter into the wearer’s nose. Many types of masks are available
such as non-woven mask, reusable mask, N95 mask and cloth mask etc. The
majority of commercial masks are non-woven masks which are made up of
polypropylene fibre. The main drawback of non-woven masks is their discomfort
due to lack of breathability. This problem is solved by utilizing natural fibres as one
of the raw material in non-woven and using them in the mask. Bamboo fibre is a
natural celluloid fibre having good comfort properties with antimicrobial
properties. Hence an attempt is made in this review article to examine the important
properties of bamboo fibre and to evaluate its potential as a protective barrier
material in non-woven face masks.
