Published: December 2023

Cat ownership is common in Chile, but data on the regional prevalence of infectious agents are limited. A sero-molecular survey of 120 client- or shelter-owned domestic cats in greater Santiago was performed. Whole blood DNA was tested for the novel hepatitis-B-like virus, domestic cat hepadnavirus (DCH) by conventional PCR (cPCR) and quantitative PCR (qPCR), and for feline leukaemia virus (FeLV) by qPCR. Point-of-care serology for FeLV p27 antigen and antibodies recognising feline immunodeficiency virus (FIV) p15 and p24 was performed. DCH DNA was detected in the serum of 2/120 cats (1.67%). Sequencing and phylogenetic analysis showed that the DCH detected in Chile occupies a position outside the main clustering of DCH in the near-complete genome tree. Progressive (antigen-positive, provirus-positive) and regressive (antigen-negative, provirus-positive) FeLV infections were identified in 6/120 (5%) and 9/120 (7.5%) of cats. A total of 2/120 (1.7%) cats had dual FeLV/FIV infection, and another 2 cats had FIV infection alone. This study shows that the global footprint of DCH includes South America with a low molecular frequency in Chile, similar to that reported in the USA. Progressive FeLV infection is relatively common in urban Chile, and male cats are at greater risk than females. Testing and control measures for pathogenic retroviruses are indicated. The potential impact of FeLV, FIV and DCH on Chile’s wildcat species is worthy of further investigation.

Published: December 2023

At least 20,000 plant species produce latex, a capacity that appears to have evolved independently on numerous occasions. With a few exceptions, latex is stored under pressure in specialized cells known as laticifers and is exuded upon injury, leading to the assumption that it has a role in securing the plant after mechanical injury. In addition, a defensive effect against insect herbivores and fungal infections has been well established. Latex also appears to have effects on viruses, and laticifers are a hostile environment for virus colonization. Only one example of successful colonization has been reported: papaya meleira virus (PMeV) and papaya meleira virus 2 (PMeV2) in Carica papaya. In this review, a summary of studies that support both the pro- and anti-viral effects of plant latex compounds is provided. The latex components represent a promising natural source for the discovery of new pro- and anti-viral molecules in the fields of agriculture and medicine.

Published: December 2023

Nanoparticles have been identified in numerous studies as effective antigen delivery systems that enhance immune responses. However, it remains unclear whether this enhancement is a result of increased antigen uptake when carried by nanoparticles or the adjuvanticity of the nanoparticle carriers. Consequently, it is important to quantify antigen uptake by dendritic cells in a manner that is free from artifacts in order to analyze the immune response when antigens are carried by nanoparticles. In this study, we demonstrated several scenarios (antigens on nanoparticles or inside cells) that are likely to contribute to the generation of artifacts in conventional fluorescence-based quantification. Furthermore, we developed the necessary assay for accurate uptake quantification. PLGA NPs were selected as the model carrier system to deliver EsxB protein (a Staphylococcus aureus antigen) in order to testify to the feasibility of the established method. The results showed that for the same antigen uptake amount, the antigen delivered by PLGA nanoparticles could elicit 3.6 times IL-2 secretion (representative of cellular immune response activation) and 1.5 times IL-12 secretion (representative of DC maturation level) compared with pure antigen feeding. The findings above give direct evidence of the extra adjuvanticity of PLGA nanoparticles, except for their delivery functions. The developed methodology allows for the evaluation of immune cell responses on an antigen uptake basis, thus providing a better understanding of the origin of the adjuvanticity of nanoparticle carriers. Ultimately, this research provides general guidelines for the formulation of nano-vaccines.

Published: December 2023

Recently, Asia has experienced significant damage from extreme precipitation events caused by climate change. Improving the accuracy of quantitative precipitation forecasts over wide regions is essential to mitigate the damage caused by precipitation-related natural disasters. This study compared the predictive performances of a global model trained on the entire dataset and a clustered model that clustered precipitation types. The precipitation prediction model was constructed by combining convolutional long short-term memory with a U-Net structure. Research data consisted of precipitation events recorded at 10 min intervals from 2017 to 2021, utilizing radar data covering the entire Korean Peninsula. The model was trained on radar precipitation data from 30 min before the current time (t − 30 min, t − 20 min, t − 10 min, and t − 0 min) to predict the precipitation after 10 min (t + 10 min). The prediction performance was assessed using the root mean squared error and mean absolute error for continuous precipitation data and precision, recall, F1 score, and accuracy for the presence or absence of precipitation. The research findings indicate that, with sufficient training data for each precipitation type, models trained on clustered precipitation types outperform those trained on the entire dataset, particularly for predicting high-intensity precipitation events.

Published: December 2023

The excavation of a super-large foundation pit is a greatly risky project in coastal water-rich silt strata, and it is of great significance to establish a numerical model to analyze and predict the stability of the foundation pit retaining its structure for safe construction. Based on a geological investigation report and key node monitoring data, the model parameters have been modified. Subsequently, the random field theory and numerical analysis were employed to proceed with deterministic analysis and uncertainty analysis, respectively. Using the uniform distribution method, Gaussian distribution method and the covariance matrix method to generate a random field model, finite difference software was applied to analyze the impact of spatial variability of cohesion and the internal friction angle on structural deformation. The study shows that the overall distribution of axial force is small on both sides and large in the center, and the axial force is larger near the shaped region. Due to the principle of “lever”, there is a tendency for the horizontal displacement of surrounding piles to partially rebound from the pit when the bearing platform pit is excavated. The spatial variability of the internal friction angle and cohesion has an important influence on the numerical value of the enclosure structure and surface deformation, and the variation pattern is basically unchanged.

Published: December 2023

Climate change and land use/cover change (LUCC) are two major factors that alter hydrological processes. The upper reaches of the Tarim River, situated in the northwest region of China, experience a dry and less rainy climate and are significantly influenced by human activities. This study comprehensively assessed the impacts of individual and combined climate changes and LUCCs on streamflow. Three general circulation models (GCMs) were utilized to predict future climate changes under three shared socioeconomic pathways (SSP119, SSP245, and SSP585). Cellular Automata–Markov (CA–Markov) was employed to predict future LUCC under three scenarios (i.e., ecological protection, historical trend, and farmland development). Streamflow for the period 2021–2050 was simulated using the calibrated MIKE SHE model with multiple scenarios. The results showed that from 2021 to 2050, increments in both average annual precipitation and average annual temperature under the three SSPs were predicted to lead to an increased streamflow. In comparison to the conditions observed in 2000, under three LUCC scenarios for 2030, the grassland area decreased by 1.04% to 1.21%, while the farmland area increased by 1.97% to 2.26%, resulting in reduced streamflow. The related changes analysis indicated that the variation in streamflow during winter is most significant, followed by spring. The study predicted that climate change would increase streamflow, while LUCC would decrease it. Due to the greater impact of LUCC, considering the combined effect of both factors, runoff would decrease. The contribution analysis indicated that climate change contributed between −7.16% and −18.66%, while LUCC contributed between 107.16% and 118.66%.

Published: December 2023

The distributed Grid-Xin’anjiang (Grid-XAJ) model is very sensitive to the spatial and temporal distribution of data when used in humid and semi-humid small and medium catchments. We used the successive correction method to merge the gauged rainfall with rainfall forecasted by the Weather Research and Forecasting (WRF) model to enhance the spatiotemporal accuracy of rainfall distribution. And we used the Penman–Monteith equation to calculate the potential evapotranspiration (PEPM). Then, we designed two forcing scenarios (WRF-driven rainfall (Wr) + PEPM, WRF-merged rainfall (Wm) + PEPM) to drive the Grid-XAJ model for flood forecasting. We found the WRF-driven Grid-XAJ model held significant potential in flood forecasting. The Grid-XAJ model provided only an approximation of flood hygrographs when driven by scenario Wr + PEPM. The results in scenario Wm + PEPM showed a high degree-of-fit with observed floods with mean Nash–Sutcliffe efficiency coefficient (NSE) values of 0.94 and 0.68 in two catchments. Additionally, scenario Wm + PEPM performed better flood hygrographs than scenario Wr + PEPM. The flood volumes and flow peaks in scenario Wm + PEPM had an obvious improvement compare to scenario Wr + PEPM. Finally, we observed that the model exhibited superior performance in forecasting flood hydrographs, flow peaks, and flood volumes in humid catchments compared with semi-humid catchments.

Published: December 2023

This research offers an exploration of the social networks within two distinct watershed groups in the Hudson River, New York State, USA: citizen-based and agency-based organizations. Through a social network analysis of their operations and interactions, this study unveils the complex dynamics and roles of individual nodes in facilitating nine types of connections, such as political and financial, within these networks. The citizen-based organization demonstrated denser and more cohesive networks, suggesting robust relationships and enhanced resilience and adaptability. In contrast, the agency-based organization exhibited more hierarchical networks. This study employs both network-level and node-level analyses to examine the social networks within watershed groups. Our network-level analysis focuses on metrics such as density, average degree, and hierarchy, while our node-level analysis examines clustering coefficients and influence. It also explores ego networks through an analysis of their density and the effective size of structural holes. Our finding is that the social networks of the two groups are quite distinct, and there is limited exchange of information and resources between them. However, we discovered that effective communication among a few well-connected individuals (e.g., those with high influence values) within each group can enhance the effectiveness and resilience of these networks. These analyses aim to provide a detailed understanding of the social dynamics within regional watershed groups.

The influence of the mesh arrangement method on the results of video endoscopic treatment of ventral hernias remains a debatable issue. The contact of the mesh with adipose tissue during IPOM plasty leads, on the one hand, to the formation of seroma, the development of purulent complications, which can cause relapse, and a high risk of intestinal damage, complications associated with the mesh, and postoperative pain, on the other. The technique of laparoscopic IPOM plastic surgery is also ineffective in diastases, since it does not strengthen the white line of the abdomen. The best place for mesh implantation, according to the world’s leading gerontologists,is the retromuscular space. The EMILOS technique developed by the German surgeon W. Raingold combines the advantages of subway plastic surgery and the laparoscopic IPOM method. The EMILOS operation has mainly less surgical trauma, fewer postoperative complications, low recurrence rate and high economic efficiency.

The study included 23 patients with acute intestinal ischemia. The average age of the patients was 59,9 ± 15,0 years, the male prevailed — 17 men (73.91 %) vs. 6 women (26.09 %). The diagnosis of a new coronavirus infection caused by SARS-CoV-2 was confirmed in all patients by the results of PCR tests (polymerase chain reaction). All patients underwent Computed Tomography of Pregnant Women with contrast examination, which was validated by a valuable instrumental study in patients with COVID-19 with suspected acute intestinal ischemia. It was confirmed that ischemia of the small intestine is the most prominent case in surgical detection, resection of the necrotic part of the small intestine with the formation of anastomosis was the most common surgical procedure, it was performed in 14 (60,85 %) patients, in 7 (30,45 %) patients resections of the large intestine were performed, and only 2 (8,7 %) patients underwent open thrombectomy. Histopathological examination was performed in 21 patients (91,30 %), revealed general symptoms, including necrosis, ulcer, hemorrhage in 11 patients (47,82 %), neutrophilic infiltration in 7 patients (30.4 %) and abscess in 3 patients. (13,04 %). An assessment of the dynamics of blood biomarkers in patients included in the study showed a steady increase in such indicators as D-dimer, LDH, ferritin and IL-6. Because of the high incidence of GI ischemia, clinicians should always be on the lookout for this disease in order to prevent its progression and promptly treat any complications. Elevated levels of CRP, lactate and D-dimer may determine predictive value as possible prognostic factors as they can be found in any patient with severe course of COVID-19.

The relevance of studying the ancient Koryak culture of the Northern Okhotsk region is noted. A difficult problem is the study of its funeral rituals. One of the most promising sites for studying the ancient Koryak burial complexes is Cape Bratyev and Cape Bukhty Malaya Astronomicheskaya. The article discusses wooden items from the burial in the niche under a stone at Cape Bratyev in the area of Babushkin Bay. The wooden objects are identified as parts of a compound bow. The closest to Cape Bratyev bow fragments are ancient Eskimo bows. Information is provided about wooden finds at ancient Koryak sites. The presented data demonstrate the research potential of the ancient Koryak burial complexes in the Northern Priokhotye. The unsatisfactory condition of some burials, as well as natural destruction of the rock cliff and movement of boulders, among which the burials are located, determine the need for immediate research of these archaeological sites.

For the first time, Russia's Far North-East prospects for hydrogen production by the method of water electrolysis, using climatic energy sources and ultra-fresh mountain-river water, are comprehensively assessed. Taking into account the identified regional features, it is calculated that, with the current technical level of development, the amount of hydrogen produced in the region will be controlled just by the amount of used ultra-fresh mountain-river water. Thus, using no more than 10 percent of the general runoff (18 billion m3 water), it is possible to annually obtain 2x109 tons of "green" hydrogen through the operation of wind and solar power plants. To accommodate the latter, it is ecologically feasible to use the areas in mountain tundras and forest-tundras on flattened and flat watersheds.

The geological and isotopic age of the deposits in gold-sulfide-quartz and gold-silver formations of the Gonzhinsky gold ore center in the Amur gold-bearing province is considered. The formation of the gold-sulfide-quartz deposits of Pioneer, Anatolyevskoye, and Alexandra is paragenetically associated with the Burindinsky monzodiorite complex of intrusions and dikes, with the estimated potassium-argon age of 92-116 Myr; the isotopic age of the Burindinsky complex diorite array was established by the U-Pb method by zircons as 117.8 ± 2.6 Myr within the Aptian stage of the Early Cretaceous. For gold-silver deposits (Pokrovskoye, Burinda), a paragenetic relationship of gold-silver mineralization with a complex of subvolcanic intrusions and dikes of the Early Cretaceous Taldan complex has been established. They were formed at the subvolcanic level and belong to the Barremian time. The Rb-Sr age of the most productive Pokrovsky gold-silver deposit is 131 ± 12 Myr.

In xenoliths of gabbro-diorites from of the Levo-Seimkan granite massif, the disseminated sulfoarsenide and sulfoantimonide mineralization with predominant antimonial nickeline and with the gersdorfitekrutovite series minerals has been revealed, with a constant Sb admixture in gersdorfite (from 1.1 to 2.4 wt. %) and nickeline (Sb 3.2-12.2 wt. %) in association with pyrrhotite. In a new ore occurrence (Puglivy Creek, Arman River basin, 2 km from the mouth), in a stockwork of quartz-chlorite veins localized directly in the granites of the Levo-Seymkan massif, the Co-As-Bi-Te-Au mineralization has been established. Ore mineral nests and inclusions are represented by glaucodote (Ni under 3.28 wt. %), associated with native Bi, bismuthine, tellurovismuthite, hedleyite, and native Au. Ni-Co mineralization of disseminated ores from gabbro-diorite xenoliths from the Levo-Seymkan massif and from the stockwork localized in the massif granites (roof outshot in the Puglivy Creek), as well as from veins and veinlets in contact hornfelses (Puglivoye and Obkhod deposits). It has been found that mineral phases are not as characteristic for mineralization in granites and Ni hornfelses, and that the Co/Ni increases with distance from the Levo-Seimkan massif due to the lower migration ability of Ni relative to that of Co in the course of successive geochemical differentiation.

CAHİLİYE DEVRİ VE HZ. PEYGAMBER DÖNEMİNDE ADAM ÖLDÜRMEDE TAKİP EDİLEN UYGULAMALARIN KARŞILAŞTIRMALI İNCELENMESİ
Authors: Altuntaş Hacı Mehmet
Published: December 2023

Câhilye döneminde geleneksel olarak oluşan düzeniyle varlığını sürdüren hukukî işeyiş Hz. Peygamber’in Medine toplumunda oluşturduğu siyasi yapıda sistemli bir şekilde uygulanılır hale geldi. İslâm öncesinde kabilelerin güçlerine nispetle çoğu zaman güçsüz olanların zarar gördüğü, zararlarını tazmin edemedikleri ve güçlülerin işledikleri cinayetlerin hesabını vermedikleri düzen sona erdi. Yeni düzende Hz. Peygamber toplumun siyasi lideri olarak aynı zamanda hukuki işleri de uhdesine aldı. Hukukun işletilmesi kabilelerin inisiyatifinde olmaktan çıkarılıp merkezi siyasi yapıda bütün bir topluluğun sorumluluğu haline geldi. Ve hem tarihsel olarak o güne değin varlığını koruyan hem de çevre topluluklarda uygulanan kısas adam öldürmelerde baş vurulan önemli kural olarak İslâm toplumunda da varlığını korudu. Cinâyet olaylarının önüne geçmede önemli bir engelleyici çare olarak uygulanan kısas Kur’an’da da kendisine yer bulmaktadır. İslâm diyet ödeme yoluyla, çatışan tarafların anlaşmasını, kısas isteyerek kâtilin öldürülmesi yerine onun canının bağışlanmasını tavsiye etti. Diyet on deve olarak bütün cinâyet olaylarına kabile farkı gözetmeksizin eşit uygulandı. Câhiliye döneminde bazı güçlü kabilelerin kendi üyeleri için çift diyet talepleri söz konusuydu. İslâm kabile üstünlüğüne son verip her bir bireyi inanç temelinde eşit haklara sahip olarak tanıdı. Câhiliye döneminde de uygulanan, faili meçhul cinâyetlerde sorumluyu bulmak ve yaşanan can kaybının diyetinin ödetilmesini sağlamak amacıyla gerçekleştirilen kasâme uygulması İslâmî dönemde de varlığını korudu.

Following the Hero’ s Memories: The Role of Memory as a (Re)construction of the Narrative in the Legend of Zelda: Breath of the Wild
Authors: Vera Esteban
Published: December 2023

This paper discusses the concept of the hero and the role of memory as an object of (re) construction of the world in the narrative of the Nintendo digital game The Legend of Zelda: Breath of the Wild. Through the analysis of how memory is reconstructed in Link and the characters that inhabit Hyrule, memories, historical and social memory, monuments, documents, space, and gameplay within the same digital game are also reconstructed. Testimonial memory, in turn, will help remember and construct the narrative of Link’s personal and social history by reconstructing the story. The personal experience that the player has while interacting with the game through the act of playing can build the metadiscourse between memory and narrative to understand the hero and his journey through the world. In this sense, the importance of the character Link within the game is affirmed, as he is a much more complex subject than a simple archetype within the game mechanics.

Osteoporosis is one of the complications that affects patients with chronic kidney disease (CKD). To treat this complication, denosumab is one of the prescription drugs. We investigated articles with the keywords of "CKD" OR "Chronic Kidney Disease" AND "Denosumab" in the title in PubMed database. Evidence shows the advantages of using denosumab over bisphosphonate in CKD patients. Also, some studies stated that this drug does not have a negative effect on kidney function and its effectiveness is the same in people with different kidney function. The common complication of taking this drug is hypocalcemia, which can be controlled with appropriate approaches in these patients. It is also important to pay attention to adherence and continuity of medication. Some studies also stated that this drug is contraindicated in CKD patients (stage 4 and 5).
Assessing the feasibility of using tillers and mini-tractors for mechanizing work in forest nurseries

At the moment, a significant part of the equipment operated in permanent forest nurseries is worn out by 70-80%. At the same time, the existing equipment has excessive productivity, which in conditions of small forest nurseries leads to excessive operating costs. The area of sowing departments and fallow fields in modern nurse-ries rarely exceeds 3 hectares, which makes it possible to accept small farms as the closest analogy in terms of the volume of agrotechnical work. Based on the cluster analysis of the nomenclature of existing machines and tools of various types, the options for re-equipping forest nurseries with small-sized mobile energy means (SMEM) and small-scale mechanization means (SMM) in modern geopolitical conditions were evaluated. Firstly, the information on ploughshares, disc harrows, spreaders of solid fertilizers, sprayers, precision seeders and cul-tivators for aggregation with tillers and mini-tractors available for purchase was analyzed. Secondly, the neces-sary level of power-to-weight ratio of the heavy vehicle has been determined to perform the entire list of mecha-nized work on growing planting material in a forest nursery. Thirdly, the economic feasibility of using tillers and mini-tractors to perform work in forest nurseries by calculating "hourly operating costs" was evaluated. The re-duction of the range of SMEM and SMM models offered on the market of the Russian Federation is not a limiting factor. There are enough machines and tools of Russian, Belarusian and Chinese production to ensure mecha-nized work in a forest nursery. The most effective are SMEM with an engine power of 30 kW and a load capacity of 700 kg rear suspension. SMEM is economically feasible to use with an annual volume of work equivalent to 60 hectares of conventional arable land, or less. With large volumes, the use of more productive tools with a trac-tor of traction class 1.4 is economically justified.

When organizing the work of logging machines, it is necessary to take into account not only their technical characteristics, but also their adaptation into a single digital space. In the absence of synchronization, the ability to control the volume of harvested wood, optimize sorting plans for maximum benefit, remotely monitor the technical condition of the tires, organize their effective maintenance and repair is reduced. The software used by the manufacturers of logging equipment "Ponsse", "Komatsu", "John Deere" was evaluated according to fourteen criteria for parameter control, machine maintenance management, personnel training using the method of intergroup relations (Jacquard measure), and visualized with a cluster diagram. The basis of digital systems is software solutions that allow integrating machines of only one brand into a single information space of the company, which narrows the field of their activity, and therefore reduces the effectiveness of their application. The existing models of digital ecosystems of the companies under consideration lack a module related to logging planning, which does not allow to effectively link the required amount of equipment (harvesters, forwarders, loaders, skidders) with the planned volumes of timber harvesting, as well as to coordinate their work and productivity with maintenance and repair. The imbalance of output volumes by different machines used in logging leads to downtime of the most productive (head) machines and a decrease in the total volume of their output to a minimum at one of the main operations.
