Laterite steel is steel that has a nickel content of up to 2%. The nickel content can produce steel with superior properties such as: high strength, corrosion resistance, and good weldability properties. With the superior nature of laterite steel is needed in the main tool of the indonesian national tantara weapon system. To find out the performance of damage to bulletproof materials, then conducted research on this laterite steel as a tough armour material by conducting research in the form of mechanical properties testing (Hardness, and Impact) and microstructures (Metalography). Samples are prepared in accordance with ASTM standardization. Based on the results of the hardness test, the average values of F and T samples were 663.9 HVN and 170.7 HVN. Material F qualifies as a ballistic resistant material (armour) because the hardness obtained in accordance with the classification and can withstand bullet penetration well. Then the impact test obtained the average value of the F and T samples is 9 joules and 148 joules. For F samples, the type of fault is a granular fracture and a T sample of the type of fault is a tenacious fracture. As a result of metallographics, sample F has a corrected phase is upper bainite as a matrix and martensite is generally shaped like a fine needle. Then the T sample has a formed phase is dominated by ferrite with soft and tenacious properties. As well as perlite as a matrix with quite hard and strong properties.

Riding a motorbike possess to a dangerous situation because of its stability and balance. Crosswind has a significant impact on riding since, with a strong gust, it can easily drive the motorbike off the road or into another lane or traffic. A numerical study has been conducted to investigate the aerodynamic loads of the drag, side, and lift coefficient and to analyze the flow pattern occurs of the motorbike with different types of fairing when travel under various angle of crosswind that was set ranging 0◦, 15◦, 30◦, 60◦ to 90◦. Two models of Yamaha YZF M1 with different types of fairing were designed using SolidWorks 2020 and then simulated using Ansys CFX with 25m/s as the velocity for main and crosswind inlet. The aerodynamic loads coefficient was calculated for each model and the streamlines flow were analyzed. The aerodynamic loads coefficient was found increases as the yaw angle increases. Half fairing model was found to have higher aerodynamic coefficient compared to fully fairing model since half fairing model was not aerodynamic shape.
Preliminary Insights into the Formation of Minimal Winning Coalitions in Western Europe
Authors: Improta Marco
Published: July 2023

Coalition governments have prompted a stream of prominent research since the birth of modern political science. Several studies have been performed on the lifecycles of cabinets, focusing particularly on their formation and duration. The first investigations into such issues were carried out using game theoretic approaches. In their ground-breaking works, William Riker and Lawrence Dodd argued that office-seeking outcomes, i.e. minimal winning coalitions, are more frequent and stable than other cabinet types. However, more recent research suggests that this proposition is disputable. By relying on an original multilevel dataset on West European cabinets, this study examines the actual rationality of minimal winning coalitions by asking whether they have been more recurrent than different government formulae, as predicted by game theory. The analysis finds that such coalitions have not been formed more frequently than non-rational cabinet solutions, i.e., oversized majority cabinets. In addition, the article showcases that minimal winning coalitions may occur in both polarised and less polarised West European political systems. By shedding light on office-based game theoretic propositions and their observable empirical records, this study contributes to the scientific examination of a fundamental stage of democratic governance in Western Europe.

The Saharawi Arab Democratic Republic, the Art of Resistance and How to Constitute a Country While Under Occupation
Authors: Lourenço Isabel , Teixeira Jorge
Published: July 2023

The Frente POLISARIO, a liberation movement that aimed to achieve freedom of the then Spanish Sahara, was funded in 1973. In 1976, one year after the invasion of Morocco and Mauritania of Western Sahara, POLISARIO proclaimed, in the name of the Saharawi People, the Saharawi Arab Democratic Republic (SADR). Western Sahara has been on the United Nations’ list of Non-Self-Governing Territories under Chapter XI of the UN Charter, since 1963. Forty-seven years later, the fight for the future of Western Sahara still ensues. Despite all judicial decisions against its claim, Morocco still occupies Western Sahara and proclaims it is part of its national territory. On the other side, Frente POLISARIO, adhering to International Law and their legitimate rights to Self-Determination, still fights. Morocco resorts to a mix of tactics: war, propaganda, fake news, defamation, imprisonment of dissidents, human rights violations, and Geopolitical Alliances. In 1991, under the auspices of the UN and AU, an agreement on a Referendum to determine the Liberation of Western Sahara or the Annexation into the Kingdom of Morocco was achieved, but was never materialized. A UN Mission, Misión de las Naciones Unidas para la Organización de un Referéndum en el Sáhara Occidental (MINURSO), was established. Morocco, however, did not respect the terms of the agreement, boycotting the referendum. Between 1991 and 2020, a cease-fire was in place. In November 2020, a Moroccan military assault against a peaceful protest of Saharawi civilians against a new breach of Military Agreement No. 1 triggered Frente POLISARIO to declare the cease-fire null and void and to resume military action. In this paper, we will try to clarify what the Saharawi Arab Democratic Republic is and what Frente POLISARIO is. To achieve our goals, we have examined the SADR Constitution and how the political actors implement the ideas and ideals of the Constitution reflected on Frente POLISARIO. Our analysis has found a country ready and able to implement the structure of a functioning Modern Democratic State with the necessary prepared human resources.
Under economic stress rational behavior may yield increased consumption of pricier goods
Authors: Quante Lennart , Otto Christian , Willner Sven Norman , Middelanis Robin , Levermann Anders
Published: July 2023

The behavior of consumers is one of the elementary market forces. Thus, changes in consumed quantity in response to changing prices are an important determinant of economic behavior. Here, we show analytically under minimal assumptions that in an out-of-equilibrium market it can be rational to buy more of a good in spite of increasing prices.When rational consumers maximize their utility, consumption is driven by two factors, the relative price change of goods and their substitutability. Influenced by heterogeneous prices between suppliers and goods, the budget-driven preference for goods with the least price increase is competing with the utility-driven substitution of goods. This leads to a stabilizing feedback loop emerging from any utility function that is strictly monotonically increasing. We illustrate this feedback dynamics in an agent-based model with utility-optimizing consumers under regionally heterogeneous weather-induced supply failures. The resulting relation between changes in prices and quantities are predominantly in line with macro economic observations, but a positive correlation between price and quantity emerges in out-of-equilibrium situations. Thus, in a stressed economy rational consumers might buy more of pricier goods in spite of budget constraints.
Development and Validation of the Glasgow Sensory Questionnaire Short (GSQ-14)
Authors: Millington Elliot , Simmons David
Published: July 2023

Many autistic people find that differences in their sensory processing present challenges when interacting with the world, especially when not supported. Understanding and addressing these sensory differences is crucial for improving the quality of life of autistic people. The Glasgow Sensory Questionnaire (GSQ) is a questionnaire that asks questions about the hyper- and hypo-reactivity of the five main senses, as well as proprioception and the vestibular sense. The standard questionnaire contains 42 questions, which can be burdensome for those completing it. This study constructed the Glasgow Sensory Questionnaire Short (GSQ-14) using secondary data from 823 participants and a Confirmatory Factor Analysis. Validation data were separately collected using an online sample of 75 participants who completed the GSQ-14 and Autism Spectrum Quotient (AQ) Short. The GSQ-14 demonstrated good internal reliability and significant correlations with measures of autistic traits and sensory processing differences in both the construction and validation samples. The GSQ-14 offers a valid and concise alternative to the original GSQ for measuring sensory processing differences, facilitating use in both clinical practice and research.

Onconephrology: The time has come
Authors: Kolesnyk M.
Published: July 2023

Why did this time come and how this direction (subspecialty) onconephrology formed?

The effect of actual renal cancer (RC) or malignant lesions of extrarenal localization on the condition of the kidney is realized in different ways. Renal cancer can occur in a healthy kidney or a patient with CKD of any stage, moreover, the higher the stage, the higher the risk of renal cell carcinoma (RCC) [1]. It can cause kidney damage due to the formation of almost the entire spectrum of glomerulopathies or A-amyloidosis [2]. 25-30% of patients with RCC before surgery have CKD of various stages [3].

In addition, almost any extrarenal localization of a malignant process can directly or indirectly cause damage to healthy kidneys or worsen the course of pre-existing CKD, and an increase in its stage limits the options for choosing a treatment option [4].

Antitumor therapy, as it has significant nephrotoxic potential, can be another source of various glomerulopathies, acute tubulointerstitial nephritis, acute kidney injury, and increased rate of progression of CKD [5].

In general, it became clear that RC and malignant processes of extrarenal localization can cause a wide range of negative kidney consequences; under both scenarios, treatment results, quality, and life expectancy of cancer patients deteriorate significantly.

The issue of starting or stopping the use of dialysis renal replacement therapy methods, kidney transplantation in patients who have survived cancer, and the risks of developing cancer in patients after kidney transplantation and its treatment is difficult to resolve.

This is far from the complete list of reasons that encouraged the American Society of Nephrology to hold the first onconephrology forum in 2011, including the first demonstration of the need for the formation of a new component of nephrology, onconephrology.

In 2014, the International Community on Cancer and Kidneys (C-KIN) was established, and in 2015, the European Organization for Research and Treatment of Cancer (EORTC) was founded. In 2017, C-KIN launched the Journal of Onconephrology (JON).

In 2019, for the first time in Ukraine, at the national oncourology conference, the report "Onconephrology: the time has come" was published, which caused a lively discussion.

Since that time, at all nephrology events of the Ukrainian National Academy of Sciences and the National Academy of  Medical Sciences, the onconephrology topics were discussed.

In 2022, the "Onconephrology" module was included in the specialization program in nephrology, which is carried out at the State "Institute of Nephrology of NAMA of Ukraine" (order of the Ministry of Education and Culture No. 159-d of 06.09.2021).

Therefore, solving the majority of the components of the problem of the combination of oncopathology and kidney damage requires either the participation of a multidisciplinary team (oncologist, nephrologist, intensivist, urologist, hematologist, etc.), or a specialist who possesses the listed knowledge and skills in the necessary volumes, i.e. onconephrologist.

Microscopic polyangiitis (MPA) is one of the three clinical phenotypes of vasculitis associated with antineutrophil cytoplasmic antibodies (ANCA). Although MPA is considered a rare form of ANCA-associated vasculitis (AAV), clinical evidence shows that it is fairly common among nephrologists, as it manifests as a systemic, weak-immune vasculitis affecting glomerular capillaries, resulting in necrotizing glomerulonephritis (GN) diagnosed in nearly 100% of MPA patients. The issue of AAV in general, and MPA specifically, has gained significant importance in the context of the ongoing SARS-CoV-2 coronavirus pandemic, as both conditions share common anatomical sites of infection and inflammation. This study presents three new cases of MPA in post-COVID-19 patients. The analysis and presentation encompassed demographic data, patient history regarding comorbidities, details of follow-up care, chronology with COVID-19, and laboratory findings at the time of MPA diagnosis. A comparative analysis of the chronological progression of MPA in the documented clinical cases reveals the polymorphic nature of early-stage clinical manifestations, as well as diverse patterns of disease progression in the advanced stage. Additionally, we provide a brief literature review on diagnostic challenges, pathogenetic mechanisms underlying the relationship between SARS-CoV-2 and AAV, and peculiarities of clinical presentations in early and advanced stages of MPA.

The study of immune mechanisms during pregnancy is an important area of research aimed at understanding the immunogenesis of pregnancy and its complications. One such complication is nephropathy, which requires accurate prediction of its course and appropriate therapy.

The present study aimed to assess the blood levels of T-lymphocytes (T-helper, T-suppressor/cytotoxic), B-lymphocytes, and markers of their activation in pregnant women, with a particular focus on patients with preeclampsia (PE).

Methods. Using a cellular cytofluorimeter and the corresponding test systems, we determined the relative levels of immunocompetent blood cells such as CD3+, CD4+, CD8+, CD19+-l with the expression of HLA-DR, CD25, CD5 activation markers in 436 non-pregnant women and 514 pregnant women. We analyzed the characteristics of these indicators at different stages of pregnancy, specifically before (1-4 groups) and after (5 group) 20 weeks. In the second stage, we performed an analysis of the indicators in 107 women with PE, 14 women after PE, and 54 pregnant women in the reference group without complications at 20+ weeks. This analysis included T- and B-cell studies of these patient groups under in vitro conditions with autoserum and inactivated serum.

Results. The first weeks of pregnancy were characterized by a high relative level (%) in the blood of T-l and subpopulations of T-h and Ts/c, as well as their activation according to the expression data of DR, CD25 (for CD4+-l), and CD5 (for CD19+-l). These indicators significantly decrease from 20 weeks of pregnancy and become comparable to the levels in non-pregnant women. The percentages of CD3+4+25+-l and CD19+5+-l are below the normal range, indicating a decrease in T-helper cell and B-cell activation during this period of pregnancy. In patients with PE after 20 weeks of pregnancy, the relative levels of T-l, B-l, T-h, and Ts/c did not differ from the reference group. Incubation of T- and B-l of women with PE  with autoserum in vitro almost tripled the number of T- and B-l, and the blocking effect was greater than in women without PE, with a significant difference between them; the average ratio T-l/T-las exceeded the reference in the subgroup of active manifestations of PE.

Conclusion. Studying the relative levels of T-l, T-h, T-s/c, and B-l in the blood, as well as markers of their activation, at different stages of pregnancy with in vitro detection of features of the humoral immune response as predictors of NP allows determining individual components of immunogenetic and prognostic markers for personalized therapy during pregnancy.
Neurogenic voiding dysfunction in children: challenges of wartime
Authors: Stoieva T. , Godlevska T. , Fedin M.
Published: July 2023

Neurogenic voiding dysfunction (NVD) is the result of the functional inability of the urinary bladder associated with neural dysregulation mechanisms at different levels. During the period when a child grows and thrives, the most important body systems develop. So, the influence of any traumatic events on children has very severe and delayed negative consequences. Post-traumatic stress disorder (PTSD) not only disrupts the psychological state of the child but also provokes a number of pathologies, leading to the progression of already existing problems, especially those associated with a neurovegetative imbalance. Elucidation of the causes and mechanisms of NVD development, which arose against the background of PTSD, gains ground in wartime.

NVD in children is often combined with psychobehavioral (attention deficit and hyperactivity disorders, dissociative episodes, increased anxiety, insomnia, night terrors, eating disorders) and somatic (pathology of the digestive, cardiovascular, endocrine systems, infectious diseases, etc.) problems that are exacerbated by PTSD.

Close anatomic-functional and neurovegetative interaction of the pelvic organs determines the development of concomitant colonic dysfunction, which very often accompanies NVD. Unfortunately, because of the great variety of clinical manifestations of bladder and bowel dysfunction, the combined pathology is often overlooked, and diagnosed late, which negatively affects the child's quality of life and psychological state.

Attention to the combined dysfunction of the bladder and bowel, timely diagnosis and proper correction with the use of pathogenetic-directed therapy, adequate nutrition, and long-term psycho-rehabilitation measures are necessary measures in the effective management of children in wartime.
Onconephrology: Renal cancer
Authors: Kolesnyk M.
Published: July 2023

Renal cancer (RC) ranks eighth among the most prevalent oncopathologies, making it one of the most widespread types of cancer. Over the last decade, there has been an average annual increase in morbidity of 2 percent. RC is a collective term that encompasses parenchymal tumors and pelvis tumors with distinct histologic characteristics.

Renal cancer can appear in intact kidneys and cause additional damage except for the actual tumor process, or in patients with previously affected kidneys.

The main treatment option for renal cell carcinoma (RCC) is surgery, which can be performed through various approaches, including open-access surgery, laparoscopic surgery, and robotic-assisted surgery. These surgical techniques enable the performance of radical nephrectomy, partial nephrectomy, and cytoreductive nephrectomy. The selection of the surgical method and the extent of the intervention fall within the expertise of oncourologists.

Anti-angiogenic drugs, including tyrosine kinase inhibitors, humanized monoclonal antibodies, and immune checkpoint inhibitors, as well as mTOR inhibitors, are commonly utilized in the treatment of advanced-stage RCC (II-IV) or its relapse. However, it is important to note that these drugs possess considerable nephrotoxicity. Therefore, kidney status plays a crucial role in determining the appropriate treatment options, the dosage of antitumor drugs, and the potential nephrotoxicity associated with them, thereby becoming the main limiting factor affecting the quality and duration of life for RCC patients.

The present review focuses on the analysis of recent data concerning the issues mentioned above, primarily in relation to RCC, and provides recommendations for the investigation and treatment of this specific category of patients.

Hematological disorders are extremely common in the veterinary medical clinic. As they are disorders that affect blood cells in general, there are numerous causes, but the most common are nutrition, parasitic microorganisms and autoimmune diseases. The objective of the present work was to report the case of a 13-year-old Labrador retriever dog with severe hematological disorders and severe anemia, where several differential diagnoses were attempted, but a definitive diagnosis was unsuccessful. Integrative therapies were selected, thus performing an evaluation of the animal and initiating treatment based on its results and laboratory alterations using the following techniques: acupuncture, chromotherapy, Chinese phytotherapy, homeopathy, moxibustion and vitamins. The study allowed us to conclude that the treatment was efficient in increasing cell counts of the hematopoietic system in general, obtaining a significant improvement in the animal's clinical condition.

Veterinary laboratories have technologies necessary for the processing of analyses, examinations and techniques in the scientific investigation of legal and forensic expertise. This paper aims to survey and critically evaluate areas of knowledge that can be used in forensic science in the veterinary laboratory. In veterinary forensic medicine, the issues of liability for negligence, incompetence, malpractice or imprudence, both in the administrative and in the civil or criminal spheres, increase every day. The assistance provided by forensic veterinary medicine is not limited to the knowledge in legal and forensic expertise applied to living or dead animals - it also extends to the field of laboratory analysis. The investigation of a crime scene is the meeting point between science and the law, and veterinary laboratories are fundamental to meet much of the analyses, examinations, and techniques. Among the main fields of laboratory activities are serodiagnostics, toxicology serodiagnosis, toxicology, biochemistry, microbiology, pathology, necropsy and others that have fundamental importance in the elaboration of expert evidence. In these laboratories, professionals can perform analyses that contribute to the study, prevention, diagnosis and treatment of animal health problems, environmental health and zoonoses applied to forensic practice. The quality assurance of the products and services of these laboratories, combined with quality management, minimizes errors, ensures credibility, biosecurity and reliability of results. The Veterinarian is designated as the Technical Manager (TM) to assume responsibility as manager of all activities inherent to the laboratories. In this context, the veterinary laboratories deserve singular attention in the field of the analyses, exams and techniques necessary for legal and forensic investigations, and elaboration of technical reports that assist justice.

Objective: The objectives of this study were to evaluate the intubating conditions using the McGrath® Series 5 Portable Video Laryngoscope (VL) with and without a muscle relaxant.Material and Methods: This randomized, prospective study was performed in 34 patients with ASA (American Society of Anesthesiologist) I-II who required oroendotracheal tube intubation. The patients were divided into two groups asthe rocuronium group and the placebo (saline) group. McGrath® VL intubation was initiated after 90 seconds when thepatient was fully relaxed. The primary outcome was the conditions of tracheal intubation between the two groups. Thesecondary outcome were the success rate of the first intubation attempt, time to intubation, required propofol dosagefor intubation, and the anesthetic events during the intraoperative and recovery room periods were evaluated.Results: Compared to the placebo group, the intubating conditions in the rocuronium group were more acceptable(excellent or good conditions) (88.2 vs. 41.2%; p-value=0.007). There were no significant differences in the successrates of first attempt intubations (16(94.1), 13(76.5); p-value=0.4). In comparison to the rocuronium group, the placebogroup required more propofol (218 mg vs. 186 mg; p-value=0.023). The rates of intraoperative and recovery roomevents were similar.Conclusion: Overall the intubating conditions when using the McGrath® VL Series 5 Portable Video Laryngoscope usingmuscle relaxants were more acceptable than when not using muscle relaxants, but there were no significant differencesin the number of attempts, time to intubation, and anesthetic events between the study groups.

Selective Flexibility
Authors: Call Jarrod
Published: July 2023

Masculinities play a key role in how men experience and interact with the world. The majority of literature, however, explores masculinities from the perspective of straight cisgender men. This study uses qualitative methods to answer the phenomenological question of how gay men understand and experience masculinity. Participants generally described their experiences with masculinities as gay men as more flexible than normative. There were, however, notable exceptions, particularly in the context of sexual relationships where participants described preferences for normatively masculine men and the association of sexual role preference with masculinity or femininity. Additionally, some men—particularly men of color and transgender men—described experiencing stricter expectations of normative masculinity than their white cisgender counterparts. These findings indicate that gay men perform masculinities differently based on social context and highlight potential racial and gender identity discrepancies.
Curating Embodiment

In this article, we explore how ten men who took part in naked photoshoots for charitable purposes make sense of their embodiment as men. Through semi-structured interviews, we look at how participation in such a novel experience of nudity with other men underpins transformations of masculine conventions as well as some of the tensions present in these men’s accounts of the events. We highlight three significant discourses that exemplify these patterns: Nudity as Enabler of Intimacy; Surveillance and Insecurities; Producing the Natural Body. Our findings showcase the important ways that men can and do engage critically with masculinity while at the same time exploring some of the ambivalent ways that these challenges can manifest.
