Antibacterial properties and drying effects of flax denim and antibacterial properties of nonwoven flax fabric
Authors: Chun David T.W. , Foulk Jonn A. , McAlister III David D.
Published: July 2023

A modification of “AATCC Test Method 100-1999” was used for assaying for bacteriostatic/antibacterial properties of denim containing various flax concentrations. Since no direct evidence that increasing the flax content of fabric imparted the fabric with increased bacteriostatic properties was found against the control bacteria, Staphylococcus aureus and Klebsiella pneumoniae, other possible explanations for the long held presumption that flax fabric exhibited antibacterial properties was sought. Because the appearance of having antibacterial or bacteriostatic properties might be imitated if the flax content would decrease the time fabric would be moist enough for bacterial growth, the effect of drying was evaluated. When flax fabric was saturated and the moisture lost during incubation was measured, there was no improved drying associated with increased flax content. When untreated nonwoven flax was evaluated as possibly containing more ‘antibacterial’ or bacteriostatic components than scoured nonwoven flax material, the population densities increased. This increase suggests that the unscoured nonwoven flax contain compo-nents that support bacterial growth to the extent that bacteriostatic or antibacterial components, if any, are overwhelmed by the components that support bacterial growth. In tests involving the control bacteria, Staphylococcus aureus and Klebsiella pneumoniae, increasing the flax content of flax fabric did not demonstrate increased antibacterial properties.

The goal of this study was to determine the effects of different joint angles and adhesives on diagonal tension performances of the box-type furniture made from solid wood and medium density fiberboard (MDF). After drilling joints of 75º, 78º, 81º, 84º, and 87º degrees on Oriental beech, European oak, Scotch pine, and MDF samples, a diagonal tensile test was applied on corners glued with polyvinyl acetate (PVAc) and polyurethane (D-VTKA = Desmodur-Vinyl Trieketonol Acetate) according to ASTM D 1037 standard. With reference to the obtained results, the highest tensile strength was obtained in European oak with PVAc glue and joint angle of 84º, while the lowest value was obtained in MDF with D-VTKA glue and joint angle of 75º. Considering the interaction of wood, adhesive, and joint angle, the highest tensile strength was obtained in European oak with joint angle of 81º and D-VTKA glue (1.089 N.mm-2), whereas the lowest tensile strength was determined in MDF with joint angle of 75º and PVAc glue (0.163 N.mm-2). Therefore, PVAc as glue and 81º as joint angle could be suggested to obtain some advantageous on the dovetail joint process for box-type furniture made from both solid wood and MDF.

Authors: Abdel-Kader Amal Hanafy , Darweesh Hassan Hasanin
Published: July 2023

In this study, the use of bagasse fiber (BF) and unbleached bagasse pulp (BP) in a cement matrix, as a raw material, to produce lightweight construction materials is reported. The bagasse was used as partial replacement of cement at different levels: 0% (control cement), 1%, 2% 3%, and 4% by weight. The average size of bagasse fibers was less than 2 mm. Although a reduction in the physical and mechanical strength was observed, the incorporation of either fiber or pulp increased the water of consistency and setting time. A composite containing 4% of bagasse fibers can be used for lightweight concrete. FT-IR spectra showed that the BF or BP adversely affect the rate of calcium silicate hydrate (CSH) formation by decreasing its promotion.

Published: July 2023

White birch was stored in the form of bundles, wood chips, and loose slash for a period of one year to examine the changes in biomass fuel properties. The samples were collected at regular quarterly intervals to measure moisture content, CNS content, ash content, and calorific value. Data loggers were also placed into the stored woody biomass to measure the temperature change inside the piles. After the first quarter of the storage period and continuing into the next three months of storage, the moisture content showed the most significant change. The moisture content of the biomass bundles increased from 29 % to above 80 % (db). The moisture content of the pile of wood chips covered with a tarp decreased from 51% to 26% and showed a continuous decline in moisture content to the end of storage period to an average range of 16.5% (db). However, the moisture content of uncovered wood chip pile was observed to continuously increase throughout the storage period, resulting in more than double in magnitude from 59% to 160% (db). The dry matter loss was higher in wood chip piles (8~27%) than in bundles (~3%). Among the other properties, there was slightly higher loss of calorific value in wood chips (~1.6%) as compared to bundles (~0.7%) at the end of one year.
Adsorption and desorption behaviors of lignosulfonate during the self-assembly of multilayers
Authors: Deng Yonghong , Wu Yuan , Qian Yong , Ouyang Xinping , Yang Dongjie , Qiu Xueqing
Published: July 2023

Self-assembled multilayers were fabricated from lignosulfonate (LS) and poly(diallyldimethylammonium chloride) (PDAC), and the adsorption and desorption behaviors of LS on the LS/PDAC multilayers under different pH conditions were intensively investigated. Results showed that the adsorption and desorption behaviors were controlled by electrostatic attraction, hydrophobic interaction, and changes in the microstructure, which depended on solution pH. Lignosulfonates exist as colloids in solutions at low pH because of a hydrophobic interactions, and the LS colloids adsorbed on the PDAC layer because of electrostatic attraction. LS colloids started to disassociate at pH 3.5, resulting in an abrupt rise of the adsorption rate, a sharp decrease of the adsorbed amount, and a steep reduction in the surface roughness. Desorption behaviors of LS multilayers were related to the pH values of both LS dipping solution for self-assembly and the immersing solution for post-preparation treatment. Desorption of LS could be induced by a weakening of electrostatic attraction or hydrophobic interaction. A significant desorption occurred only when LS colloids dissociated in the multilayers. LS colloids were harder to dissociate in the multilayers than in the solutions because of electrostatic attraction between LS and PDAC.
Complete characterization of bagasse of early species of Saccharum officinerum-co 89003 for pulp and paper making
Authors: Agnihotri Swarnima , Dutt Dharm , Tyagi C. H.
Published: July 2023

Bagasse from early species of Saccharum officinerum-Co 89003 has 71.36% useful, long, and thick-walled fibers with good slenderness ratio, but the rigidity coefficient is less than that of Eucalyptus tereticornis and Leucaena leucocephala. The kink index and kink per mm length are lower in bagasse fiber than E. terticornis, which gives rise to fewer weak points in the fiber. Low alcohol–benzene soluble substances in bagasse induce less pitch problems and favor more homogeneity in the paper. Lignin content in bagasse is comparable to Eucalyptus globulus and Leucaena leucocephala, but α-cellulose, and pentosans are slightly lower. A higher proportion of carbon content compared to hydrogen and oxygen increases the energy value of bagasse. It produces 42.2% pulp yield of kappa number 28.2 at optimum cooking conditions, such as active alkali 12% (as Na2O), temperature 150oC, and time (at temperature) 60 min. An addition of 0.1% anthraquinone at the optimum condition improves pulp yield by 2.6% and mitigates kappa number by 3.9 units.

Authors: Mahmood Tariq , Malik Salman Akbar , Hussain Syed Tajammul
Published: July 2023

Heavy metal’s release without treatment poses a significant threat to the environment. Heavy metals are non-biodegradable and persistent. In the present study the ash of water hyacinth (Eichhornia crassipes), was used to remove six metals from aqueous solutions through biosorption. Results of batch and column experiments showed excellent adsorption capacity. Removal of lead, chromium, zinc, cadmium, copper, and nickel was 29.83, 1.263, 1.575, 3.323, 2.984 and 1.978 µgg-1, respectively. The biosorptive capacity was maximum with pH >8.00. Desorption in µgg-1 of ash for lead, chromium, zinc, cadmium, copper, and nickel was 18.10, 9.99, 11.99, 27.54, 21.09, and 3.71 respectively. Adsorption/desorption of these metals from ash showed the potential of this technology for recovery of metals for further usages. Hydrogen adsorption was also studied with a Sievert-type apparatus. Hydrogen adsorption experiments showed significant storage capacity of water hyacinth ash.
The Role of Health-Consciousness and De-stress Motivation on Travel Desire and Intention
Authors: Andrulienė Rasuolė , Urbonavičius Sigitas
Published: July 2023

Health-consciousness is an important reason for travelling to resorts that offer health and wellness services. Additionally, during stressful periods, health-consciousness may trigger de-stress motivation, which is another reason to travel to destinations that help exiting from the stressful conditions. The post-pandemic context presents a situation in which health-consciousness, together with de-stress motivation, could play an important role for travelling to nearby resorts, the services of which together with opportunities to socialize could be seen as desired objectives. However, evidence on the impact of de-stress motivation on desire and intention to travel in post-restriction period is scarce, presenting a notable research gap. This gap is addressed with modelling on the basis of goal-directed behaviour that predicts travelling with the consideration of travel desire and travel intentions. This study concentrates on the impact of health-consciousness and de-stress motivation on desire and intention to travel, with the analysis of data collected from 793 respondents in Lithuania. It was found that health-consciousness and de-stress motivation are positively related to each other and have a significant impact on both travel desire and intention.

Published: July 2023

Although the Surviving Sepsis Campaign guidelines provide standardized and generalized guidance, they are less individualized. This review focuses on recent updates in the hemodynamic management of septic shock. Monitoring and intervention for septic shock should be personalized according to the phase of shock. In the salvage phase, fluid resuscitation and vasopressors should be given to provide life-saving tissue perfusion. During the optimization phase, tissue perfusion should be optimized. In the stabilization and de-escalation phases, minimal fluid infusion and safe fluid removal should be performed, respectively, while preserving organ perfusion. There is controversy surrounding the use of restrictive versus liberal fluid strategies after initial resuscitation. Fluid administration after initial resuscitation should depend upon the patient’s fluid responsiveness and requires individualized management. A number of dynamic tests have been proposed to monitor fluid responsiveness, which can help clinicians decide whether to give fluid or not. The optimal timing for the initiation of vasopressor agents is unknown. Recent data suggest that early vasopressor initiation should be considered. Inotropes can be considered in patients with decreased cardiac contractility associated with impaired tissue perfusion despite adequate volume status and arterial blood pressure. Venoarterial extracorporeal membrane oxygenation should be considered for refractory septic shock with severe cardiac systolic dysfunction.
Extending the geographical distribution of Side-striped Jackal, Lupulella adusta (Sundevall, 1847) (Carnivora, Canidae), in South Africa

Published: July 2023

Side-striped Jackal, Lupulella adusta (Sundevall, 1847), occurs in a vast area within sub-Saharan Africa. In South Africa, the current geographical distribution is limited to eastern coastal regions. Recent sightings from north-central areas of the country suggest a wider geographical distribution. Here we report on 5,130 confirmed, repeated detections of Side-striped Jackal. Of these, 3,625 captures were from 471 new locations not previously recorded in the scientific literature, thereby expanding their current geographical distribution. These new records were captured in 33 vegetation types, including the forest and grassland biomes where they are not commonly detected.

Published: July 2023

In this reflective article, a case study, we draw upon scholarship on a critical friendship (Schuck & Russell, 2005; Silva, 2003) that grew in 2020 as we worked to assist one another in creating NWP writing programs for teachers and youth. At the heart of our professional collaboration was our desire to maintain and cultivate community engagement (Deans, Roswell, & Wurr, 2010; Preece, 2017), while advancing racial literacies in digital spaces (Price-Dennis & Sealey-Ruiz, 2021) and as we worked with a framework for instructional equity (Muhammad, 2020). Weekly meetings led us to using Padlet for 189 hours of professional development, 9 programs with 511 youth, and 7 courses with 320 students. Padlet became a location for curation, especially as we worked to promote diverse, inclusive children’s and young adult texts as models for classroom teacher and student writers.

Authors: Losada Carla Jorge dos Santos , Rammê Rogério Santos
Published: July 2023

O presente artigo de conclusão de curso teve como propósito analisar a relação do consumo excessivo de produtos de origem animal como elemento preponderante dos colapsos socioambientais, mais especificamente com a pandemia do coronavírus – COVID-19, questionando se a forma de produção alimentícia pode ser considerada um fator desencadeador do surgimento de pandemias e de violações de direitos humanos e direitos animais. A metodologia utilizada foi a teórica-explicativa, baseando-se em bibliografias, dados estatísticos e artigos científicos. Existe uma padronização de oferta de produtos no mercado alimentício com o objetivo de gerar maior rentabilidade às indústrias do setor agropecuário e outras organizações, que utilizam-se de mecanismos obscuros e práticas exploratórias, perpetuando o pensamento antropocêntrico, que geram impactos negativos ao meio ambiente e, que somam-se e colapsam as estruturas sociais, econômicas e ambientais, suprimindo direitos básicos dos animais humanos e animais não humanos. Em conclusão, ficou evidente a necessidade de discussão e mudanças dos atuais hábitos alimentares dos seres humanos, dados os lastros nexos causais nas implicações da exploração da fauna e da flora, resultando em crises sistêmicas ambientais. Revelando ser indispensável a promoção da formação de cidadãos sob a perspectiva da Educação Ambiental (EA), na ética ecocêntrica, na implementação de ações governamentais e de políticas públicas, e nos investimentos na produção sustentável pelo setor privado. Por fim, a correta regulamentação nos dispositivos legais para que assegurem efetivamente os direitos ao equilíbrio ecológico à todos os seres terrestres.

Aim. To study cardiac hemodynamic disorders in patients 3, 6 and 12 months after coronavirus disease 2019 (COVID-19).

Material and methods. Sixty-six patients with bilateral pneumonia (mean age, 36,1 years), treated for COVID-19, underwent echocardiography, Doppler ultrasound of hepatolienal blood flow vessels after 3, 6, 12 months. Patients were divided into groups based on computed tomography (CT) data: group 1 — 21 patients with CT1, group 2 — 25 patients with CT2, group 3 — 20 patients with CT 3-4. In the 3rd group, 60% of patients had excessive weight. IBM SPSS Statistics Version 25.0 was used.

Results. Three months after the disease in all groups, there was a impairment of diastolic parameters studied on the tricuspid valve. Patients of the 3rd group had pulmonary hypertension, an increase in splenic vein diameter, and the spleen area. After 6 and 12 months. in all groups, there was an improvement in right ventricular diastolic filling. In group 3, pulmonary artery systolic pressure after 6 months decreased by 6,0 (3,7; 6,5)% (p=0,03), after 1 year by another 8,6 (5,4; 9,1)% (p=0,017). The diameter of the inferior vena cava after 6 months decreased by 4,8 (2,0; 10,2)%, and a year later by another 5,0 (4,4; 6,1)% (p=0,001); the splenic vein diameter decreased after 6 months by 7,3 (3,2; 10,4)% (p=0,005). The left ventricular (LV) global systolic strain reduced after 3, 6 and 12 months.

Conclusion. All patients 3 months after COVID-19 had cardiac hemodynamic disorders, which further by 6 and 12 months tend to normalize right ventricular diastolic filling. In patients with CT 3-4, by 12 months after the disease, normalization of pulmonary artery systolic pressure was also noted, a decrease in the diameter of the inferior vena cava and splenic veins, and a decrease in the global LV systolic strain persisted.

Published: July 2023

The aim of this systematic review was to identify and analyze the findings of various studies that analyzed the changes in the color stability of maxillofacial prosthetic materials after the addition of various colorants and nanoparticles and assess the change in color after being subjected to either natural or artificial accelerated aging as well as outdoor aging. This systematic review was conducted in accordance with the guidelines of transparent reporting of systematic reviews and meta-analysis (PRISMA Statement). The primary objective of this systematic review was to evaluate the color stability of maxillofacial prosthesis. The secondary objective was to assess the effect of various colorants; pigments; opacifiers; UV absorbers-such as inorganic colorants (dry earth pigments); metal oxides; and organic colorants. The time period of the included studies extended from 2013 to 2023. Electronic database search identified a total of 217 studies. Ten studies were included to meet the research question. All 10 included studies analyzed the effect of various colorants and their exposure to various aging and weathering conditions. It was found that various pigments and nanoparticles had an effect on the color stability. Also weathering and aging conditions had a direct effect on the color stability as well. In terms of disinfection, although there was not much color difference observed, highest change in color stability was observed when rubbing or brushing of the prosthesis was carried out. In conclusion, the color stability of maxillofacial prosthetics is a critical factor that influences both patient satisfaction and the overall cosmetic look. The potential of pigments and nanoparticles to enhance the color stability of silicone-based maxillofacial prosthesis has received much research. By avoiding color fading and discoloration brought on by environmental variables including UV radiation, aging, and chemical exposure, the inclusion of various pigments and nanoparticles has been demonstrated to improve the color stability of silicone maxillofacial prostheses.

Published: July 2023

El uso de cibersexo responde a múltiples motivaciones de los usuarios que lo realizan. La literatura advierte que algunas motivaciones podrían relacionarse con indicadores de consumo problemático, como la interferencia y la preocupación asociadas a su uso. No obstante,estos estudios no siempre han considerado la posible influencia del género en la expresión y relación de estas variables. Este trabajo pretende explorar las motivaciones para practicar cibersexo y analizar su relación con los indicadores de interferencia y preocupación asociados al consumo en función del género. Para ello, 276 personas (57.25% mujeres; 43.75% hombres) de entre 18-48 años cumplimentaron el Cuestionario sobre Prácticas Sexuales Online (CPSO, Salusex-Unisexsida, 2017) que incluía cuestiones sobre estas variables. Encontrar material para masturbarse fue la principal motivación en hombres (88.1%) y mujeres (69.4%) para practicar cibersexo, seguida de relajarse del estrés en ellos (48.3%) y aprender cosas sobre sexo en ellas (41.1%). En hombres y mujeres, relajarse del estrés ( 2=6.459; p= .011; y 2=5.555; p= .018, respectivamente) y mejorar el estado anímico ( 2=4.247; p= .039 y 2=15.596; p<.001, respectivamente) se relacionaron con una mayor interferencia asociada con el consumo. Respecto a la preocupación por el consumo, en hombres se relacionó con el uso para distraerse ( 2=4.139; p= .042), relajarse del estrés ( 2=3.971; p= .046) y conocer a otros ( 2=4.395; p=036), y en mujeres solo lo hizo con encontrar material para masturbarse ( 2=13.520; p=.000). Se evidencia que el uso del cibersexo como regulador emocional -relajarse del estrés y mejorar el ánimo-sea sociaestrechamente con la experiencia de un consumo más interferente en ambos géneros. Asimismo, este uso como regulador emocional, junto a motivos sociales y de ocio parecen determinantes en la tendencia a experimentar una mayor preocupación por el consumo, pero solo en hombres. Este trabajo ha sido realizado en parte gracias a la beca predoctoral RE-DOC/2019/59 de la UJI.

Tanto las emociones y relaciones sociales positivas, fortalezas y virtudes como las características de adaptación de las personas, es decir, sus hábitos, valores, planes, habilidades y esquemas, es decir, funcionamiento psicológico en conjunción con los rasgos de personalidad, son factores que se relacionan con la posibilidad de usar estrategias que permitan generar recursos de cambio y adaptación ante eventos estresantes como la situación de confinamiento por COVID19, donde personas de todos los contextos sociales y culturales tuvieron que trasladar diversas actividades y procesos laborales, escolares y de enseñanza, del entorno presencial al ámbito virtual. En los contextos educativos, esto generó altos niveles de estrés al trasladar el aula presencial a la enseñanza virtual, sumado al aislamiento, enfermedad e incluso muertes o duelos. Por ello fue importante identificar la relación entre el funcionamiento psicológico y los rasgos de personalidad en un proceso de cambio al aula online en docentes. Participaron 198 docentes con un promedio de 42.4 años de edad. Se aplicó la Escala de Funcionamiento Psicológico Positivo Cuestionario, el Inventario de los Cinco Grandes y el Cuestionario Nuevos Contextos, Nuevas Demandas y Experiencia Docente. Se encontraron relaciones positivas y estadísticamente significativas entre todas las Subescalas del inventario de personalidad y la Escala de funcionamiento psicológico positivo, y entre ésta última y el impartir clases en línea. El estado emocional impacta en el funcionamiento psicológico positivo y viceversa, éste junto a las características de personalidad en los docentes, son un recurso importante para la adaptación a nuevas condiciones y desafíos.
Situating Latin American Critical Epidemiology in the Anthropocene: The Case of COVID-19 Vaccines and Indigenous Collectives in Brazil and Mexico
Authors: Montesi Laura , Prates Maria Paula , Gibbon Sahra , Berrio Lina R.
Published: July 2023

Diverse histories and traditions of critical epidemiology in Latin America provide an important, although underutilised, alternative framework for engaging with the embodied health inequalities of the Anthropocene. Taking COVID-19 as ‘a paradigmatic example of an Anthropocene disease’ (O’Callaghan-Gordo and Antó 2020) and drawing on ethnographic research in Brazil and Mexico on vaccination campaigns among Indigenous Peoples, we review and analyse the scope and limits of Latin American critical epidemiology in addressing Anthropocene health. While there are intersecting and parallel dynamics between diverse national and regional histories of epidemiology, we argue that the relatively differential focus on political economy, political ecology, and colonialism/coloniality in Latin American critical epidemiology, alongside the attention to non-western disease experiences and understandings, constitute a counterpoint to biomedical and specific ‘Euro-American’ epidemiological approaches. At the same time, Indigenous understandings of health/disease processes are intimately connected with territory protection, diplomacy with non-human entities, and embodied memories of violence. We examine how this presents new and challenging questions for critical epidemiology, particularly in how the ‘social’ is defined and how to address both social justice and social difference whilst also navigating the biopolitical challenges of state intervention in the era of Anthropocene health.

Published: July 2023

El estudio de las modificaciones del paisaje rural se realiza con el propósito de reunir las características de las áreas no urbanas en pequeños pueblos, con enfoque de fincas cafetaleras y su relación con el paisaje y la modernización de la agricultura en contraste con la adaptación de los cambios arquitectónicos vinculados a las nuevas tecnologías. El artículo tiene como base referencial bibliográfico, todo lo relacionad, a la conceptualización de los pequeños pueblos, sus paisajes y las características de las fincas antiguas de producción cafetalera en Brasil. La metodología utilizada en la realización del siguiente artículo es la Búsqueda Ordenada, que permite el estudio de los cuatro niveles distintos que constituyen la percepción y la comprensión de los paisajes. Los cambios en el paisaje influyen directamente en el comportamiento humano y viceversa, en tal sentido, al comprender el proceso de cambios se proporciona una mejor organización del espacio donde la relación entre humanos y paisajes pueda ser comprendida como un proceso evolutivo, donde muchos factores están relacionados, desde de la antropología hasta los fenómenos estacionales. Por lo tanto, la comprensión sobre el paisaje rural como elemento de interferencia social permite la extensión del concepto y mejor uso de los conocimientos, tecnologías y métodos desarrollados, lo que conduce a la percepción clara de las variaciones del paisaje en relación con el contexto en que se encuentra.
Integración e identidad a través del monumento: ciudad de Porto Velho

Published: July 2023

Crear símbolos dentro de una ciudad es crear memorias y, éstas confieren identidad al lugar. El objetivo de este trabajo es discutir el papel de los monumentos históricos como instrumentos para rescatar la memoria de los acontecimientos sociales, políticos y económicos dentro de la ciudad de Porto Velho, estado de Rondônia. Este trabajo se basó en investigaciones, estudios técnicos y teóricos que relatan la historia de los monumentos, los atributos arquitectónicos, la identidad y la memoria en el espacio urbano. El conocimiento de lo que es monumento/patrimonio, así como su construcción dentro del paisaje urbano, puede incentivar la producción de otros proyectos arquitectónicos. Los datos de los estudios revelan que las intenciones de simbolización están presentes en la humanidad desde sus primeras manifestaciones. El diseño arquitectónico de monumentos es exclusivo de arquitectos y urbanistas, y a través de su trabajo se establece una nueva conexión y revalorización entre pasado y futuro. Concluimos que la falta de identidad y el sentimiento de no pertenencia entre las personas y la ciudad de Porto Velho - RO, pueden estar relacionados con el desconocimiento de su historia y la falta de comprensión de que los monumentos allí establecidos son también registros de la memoria de esta misma historia, lo que puede contribuir a la desvalorización de estos símbolos y bienes públicos. Y que los estudios contribuyan de forma que se incentiven nuevos proyectos monumentales, la creación de nuevos espacios (Centro de Apoyo al Turista - CAT) o actividades turísticas que sirvan para estimular el respeto por el valor patrimonial local.
New definition of singular integral operator

Published: July 2023

Let D be a connected bounded domain in ℝ2, S be its boundary which is closed, connected and smooth or S = (-∞,∞). Let , f∈L1(S), z = x+iy. The singular integral operator , t∈S, is defined in a new way. This definition simplifies the proof of the existence of Φ(t). Necessary and sufficient conditions are given for f∈L1(S) to be boundary value of an analytic in D function. The Sokhotsky-Plemelj formulas are derived for f∈L1(S). Our new definition allows one to treat singular boundary values of analytic functions.
Management practices to offset the declining trend of alfalfa hay production
Authors: Michael Baidoo , Chandan Shilpakar
Published: July 2023

Agriculture in the United States (US) is a major industry, which is the net exporter of food. The livestock sector is a centerpiece of the industry, and the base for this sector is forage resources. A forage-livestock production system is the largest economic agricultural sector in the US, and it feeds millions of people each day. More than half of the US land area has been devoted to cultivating forage crops mainly for livestock feed. In spite of the several options of forage crops available to growers to choose for production, the suitable choice often relies on the quality and quantity of hay that can be produced by the crop to meet production objectives. Alfalfa (Medicago sativa L.), the world’s premier forage crop, remains to be the number one choice for livestock feed due to its ability to produce high yields of sustained nutritive value. However, recent data shows that on the national average, alfalfa hay yields are decreasing with a direct and indirect consequent effect on the nation’s economy. Implementing efficient agronomic management practices in the alfalfa production system is a step in the direction of successful production. Along with the initial soil fertility status, integrating production factors including phosphorus and potassium fertilization, cultivar, and harvest management can be advantageous to ensure an improved physiology of alfalfa for greater hay production in the long term.

The paper seeks to identify the essential global-economic macro-shocks resulting from efforts by consumers, firms, or government policies to reduce social distancing, which caused a sharp temporary change in the world economy during the pandemic outbreak in the second quarter of 2020. The purpose is fulfilled using a simple two-period real-business cycle model. The observed reaction of the global economy in the second period of 2020 is measured by the deviation of the time series of GDP and its components, labor, labor income, and average labor product in the USA and EU from the log-quadratic trend. The model can replicate the observed economic response by reducing the total factor productivity, labor demand, and labor supply—no need to assume sticky prices. As a sudden drop in performance is supposed, followed by a modest recovery already in the following period, it is not assumed that the government would be able to avert it in time with fiscal or monetary policy. Moreover, the assumption of variable prices and supply-side shocks does not support such a policy.

Background. Clinically significant herniated intervertebral discs in the thoracic spine are quite rare, and the tactics of surgical treatment of a group of patients with this pathology remains debatable. The thoracoscopic technique has a number of advantages in the form of a shorter hospital stay and less severe pain in the surgical area compared to standard posterior surgical access.

Aim. To evaluate the results of videothoracoscopic treatment of patients with discogenic thoracic myelopathy.

Material and methods. The article analyzes the results of treatment of 21 patients hospitalized at the Federal Neurosurgical Center (Novosibirsk). According to the results of the examination, the patients were divided into 2 groups: with mild (10 patients) or ossified (11 patients) hernias. Each patient underwent video‑assisted thoracoscopic microdiscectomy. The median follow‑up was 29 (4 to 72) months.

Results. At the time of discharge, 18 (85.7 %) patients showed no deterioration in neurological status, 2 (9.5 %) patients showed positive dynamics in the form of a decrease in the degree of hypertonicity and the degree of lower paraparesis. A satisfactory result of treatment in the late postoperative period was achieved in 14 (66.7 %) patients.

Conclusion. Video‑assisted thoracoscopic surgery is an effective and safe method of surgical treatment of patients with discogenic thoracic myelopathy.
A variant of the course of chronic subdural hematoma (clinical case)

Published: July 2023

Introduction. Doctors of various specialties face difficulties in diagnosing chronic subdural hematomas (CSDH) at different stages, usually due to the lack of an evident causal relationship between neurological manifestations of subdural hematoma and the head injury sustained several weeks or even months prior to the patient's examination. Clinically, CSDH can mimic multiple neurological disorders, and before the patient is referred to a neurosurgeon, they might be inspected by various specialists such as neurologists, physicians, traumatologists and even psychiatrists. As a results, the patient initially does not receive specialized treatment, which directly affects postoperative mortality and disabi lity in patients with this pathology.

Aim. In this paper we aim to describe a rare clinical case of atypical course of CSDH. A clinical case. A 54‑year‑old woman, after falling from a ladder about 2 m high, 1.5 months after the injury, developed depression of consciousness and tetraparesis up to 2–3 points according to the Medical research counsil Weakness scale. After examination, the patient was verified to have a chronic hemispheric subdural hematoma of large volume, transverse dislocation of the median structures of the brain by 16 mm. An injury to the cervical spine was ruled out. The patient was operated on, HSDG was removed from 2 milling holes, achieving complete washing of the hematoma and, subsequently, complete restoration of motor functions in the patient – 5 point by Glasgow outcome scale (5‑point Glasgow scale).

Discussion. This paper presents the results of treatment and observation of patients with atypical course of CSDH of traumatic origin. The main method of treatment is the surgical removal of chronic subdural hematoma by a minimally invasive method: the imposition of 2 trefination holes with removal by evacuation of CSDH.

Conclusion. The problem of early detection of chronic subdural hematomas is extremely relevant. Careful collection of anamnesis, the alertness of doctors of related specialties on this problem, the mandatory use of neuroimaging methods (computer and magnetic resonance imaging) will often help to correctly and timely diagnose, start treatment on time and increase the patient’s chance of recovery, even in cases of atypical course.
Newsmakers and news sources in the “hybrid media system” (the case of the full-scale Russian invasion coverage)

The study aims to compare leading newsmakers’ and news sources’ usage in a professional mass media and a Telegram channel. The computer-assisted method of news processing was used. As a result, we discovered that audiences of both professional mass media and new media consume the same content in different forms, and they deal with mostly the same newsmakers, with more considerable attention towards personalities for the Telegram channel and with more quotes from other mass media and accurate references for the online mass media. Therefore, we concluded that the general observation about the coexistence of professional and new media, where the former publishes classic “hard” news and the latter entertains people with information, may be questioned.
Papillary tumor of pineal region: Case reports
Authors: KM Mohiuddin , M Sailaja , I Satishrao
Published: July 2023

Background: The papillary tumor of the pineal region (PTPR) was a new distinct entity described in 2003 WHO classification and later included in the subsequent 2007 and 2016 WHO classification of Central Nervous System tumours. They are commonly associated with obstructive hydrocephalus and are difficult to distinguish from other clinical entities, more particularly pineocytoma. Due to the limited number of reported cases, treatment strategies are not well established. Case report: We report two cases of PTPR who presented with headache impaired gaze and diplopia. In first case MRI showed a cystic mass in the third ventricle and pineal region whereas the tumor had displaced the tectal plate in second case. The initial squash suggested a neoplastic lesion of probable glial origin favoring ependymoma. On microscopy, the tumor displayed papillary architecture with perivascular pseudo rosettes displaying multi layering of cuboidal to columnar cell with vesicular nucleus. Based on histological features the differential diagnostic conditions considered were choroid plexus tumor, papillary ependymoma, choroid plexus carcinoma, PTPR, and metastatic carcinoma. PTPR was confirmed on immunohistochemistry workup. Both the patients had recurrence, after one year and six months respectively. Conclusion: PTPR is an important differential diagnosis to be considered in cases where the tumoris arising in the vicinity of pineal region showing papillary architecture.

Vanishing lung syndrome vs emphysematous bulla: 2 interesting cases
Authors: S Vijay , L Sarma , P Deshpande , C Mohit , I Chaithanya
Published: July 2023

Vanishing lung syndrome (VLS) is a rare radiological syndrome in which the lungs seem to disappear on chest radiograph. It is a chronic, progressive disorder usually affecting young male smokers and is characterised by giant emphysematous bullae, which commonly develop in the upper lobes. A rare case of a 28-year-old female patient who had no history of smoking, presented with chronic cough, expectoration and weight loss, is described. Radiograph and CT chest revealed findings suggestive of giant bullous disease/vanishing lung syndrome. Bronchoscopy showed copious purulent secretions. In view of recurrent infections and weight loss, the patient referred to surgeon for possible bullectomy, after controlling the infection. Another patient was a middle aged lady who presented with breathlessness was found to have severe pulmonary arterial hypertension (PAH). CT evaluation revealed large emphysematous bulla in right lower lobe along with chronic pulmonary thromboembolism (PTE). Keywords: Vanishing lung syndrome; giant emphysematous bullae; bullectomy; young female
A Chalcolithic Burial in the Mountain-Forest Zone of the Trans-Urals
Authors: Korochkova O. N. , Spiridonov I. A. , Stefanov V. I.
Published: July 2023

We describe an unusual burial at a stratifi ed Chalcolithic site Shaitanskoye 4-6 on the coast of the eponymous lake in the Sverdlovsk Region. An individual, aged 18–35 was buried in an oval fl at-grave pit, 1.6 × 0.56 × 0.2 m in size. We give a detailed description of sixty funerary items, made of stone: three unusually large knives manufactured on thin chert plates (the nearest outcrops are found in Northern Kazakhstan and Southern Urals); a projectile head, 19 arrowheads, 18 fl int bladelets from a side-bladed tool, a polished axe-adze, a composite tool on a blade, two plates with use-wear traces, and 15 beads. Notably, some of the artifacts are made of “southern” rocks. The results of the isotope analysis indicate considerable mobility and close ties between populations of the forest and steppe Trans- Urals in the 4th and 3d millennia BC. The Chalcolithic site, which, apart from the burial, includes habitation deposits with numerous artifacts such as ceramics of various types, lithics including a large series of arrowheads and several fl int fi gurines, can be viewed as a complex archaeological object where, among other activities, rites were performed securing group consolidation.
From the History of Ethnographic Studies in the Yenisei Region: F.A. Fjelstrup’s Siberian Materials
Authors: Naumova O. B. , Oktyabrskaya I. V.
Published: July 2023

This article describes the works of Theodor (Fedor) Fjelstrup (1889–1933)—a Russian ethnographer, one of those who laid the groundwork for the systematic studies of the Turkic world of Central Asia. We used materials from the archives of the Institute of Ethnology and Anthropology RAS (F.A. Fjelstrups’ holding): the diary of the Minusinsk- Abakan 1920 Expedition and the notebook. We discuss the hitherto unknown episodes in the ethnographic studies of the Yenisei region, the foundation of the Institute for the Study of Siberia, the organization and work of the Minusinsk-Abakan 1920 Expedition, whose records we introduce, and its route. Data on settlements, utensils, clan structures, systems of kinship, family rites, folklore, and shamanic beliefs are analyzed. Using the historical approach, Fjelstrup traced the dynamism of the Khakas culture, being one of the fi rst to discuss the syncretism of their beliefs. Using materials of the Minusinsk-Abakan Expedition, we demonstrate that he implemented a comprehensive approach combining linguistic, ethnographic, and anthropological evidence. This scholarly tradition, which was widely practiced in the 20th century, maintains its importance in future studies of the Turkic groups of Central Asia.
