Published: July 2024

Crude oil is a valuable resource for boosting global economic growth. In this regard, this study examined the effect of crude oil price fluctuations on Tanzania’s economic growth from 1989 to 2022. Empirically this study utilized time-series data extracted from World Bank in particular, GDP per capital from World Development Indicators (WDI) as proxy of economic growth and Statistical Review of World Energy for Crude Oil prices. In this study, Renaissance growth theory, Autoregressive distributed lag model (ARDL), Dickey and Fuller tests, The Johansen test for cointegration, Breusch- Godfrey test for Serial correlation LM, Breusch-Pagan heteroscedasticity test, Jarque-Bera normality test, Error Correction Model (ECM), Granger Causality test, CUSUM and CUSUMSQ curves tests were used to analyse the data. This study revealed that crude oil price changes have positive and significant impact on Tanzania’s economic growth. A dollar increase in crude oil prices brings about 0.232791unit increase Tanzania’s economic upturn in the short run. The ARDL results also shows that error correction model (ECM) of -0.1000 (p= 0.0025) is significant with its value, suggesting a moderate speed of convergence to equilibrium after shock. Thus, this study recommends to policy maker and the government to ensure that they use fiscal policies that will reduce the adverse impact of the world crude oil prices hikes, finding other sources of energy and promoting research and development to explore and harness the oil fossils to produce oil and reduce oil importations and increase oil exportations to further increase economic growth.

As síndromes hipertensivas da gestação, incluindo a Síndrome HELLP (Hemólise, Elevação das enzimas hepáticas e Plaquetopenia), representam uma complicação grave da pré-eclâmpsia, afetando cerca de 7% das gestações. A origem da Síndrome HELLP está associada ao desenvolvimento placentário inadequado, estresse oxidativo e lesão endotelial, resultando em complicações graves como hemólise, disfunção hepática e plaquetopenia. O diagnóstico precoce é essencial para prevenir desfechos desfavoráveis. Este estudo realiza uma revisão integrativa da literatura, explorando os aspectos epidemiológicos, fisiopatológicos, clínicos, diagnósticos e de manejo da Síndrome HELLP. Com uma incidência de 0,1% a 0,9% nas gestações, a Síndrome HELLP ocorre frequentemente em contextos de pré-eclâmpsia grave e é caracterizada por uma elevada taxa de mortalidade materna e perinatal. A fisiopatologia envolve fatores imunológicos e genéticos, levando a disfunções vasculares e endoteliais. Clinicamente, a síndrome se manifesta por sintomas como dor abdominal, náuseas e hipertensão. O diagnóstico é confirmado por exames laboratoriais específicos, enquanto o tratamento geralmente envolve a interrupção da gravidez e cuidados intensivos materno-fetais.
Strong volcanic-induced climatic shocks on historical Moselle wine production

Published: July 2024

Abstract. In central and southern Europe, grapevine is a climate-sensitive agricultural product of large economic importance, both in historical times and today. We systematically investigated the climatic impact, focusing on volcanic-forced abrupt cooling, on two long annual records of wine production quantity (spanning 1444–1786) from the Moselle Valley in present-day Luxembourg, close to the northern limit of viticulture in Europe. We present a consistent picture of the impact of volcanic eruptions on wine production through climate. To this end, we applied superposed epoch analysis – an appropriate method for detecting episodic signals in non-stationary time-series – in combination with a bootstrap procedure to estimate the statistical significance. We also assessed the long-term relationship between different annual and seasonal climate parameters and wine production in the Moselle Valley. Robust and highly significant wine production declines occurred in the years immediately following major volcanic events. Warmer, and to a lesser extent drier, climate condition had a moderately strong, but persistent, positive effect on wine production. We also find a volcanic cooling signature in spring and summer in temperature reconstructions. However, the detected volcanic signature in the Moselle Valley wine production is considerably stronger than the one found for Central Europe in tree-ring data and is instead more akin to the strong volcanic signature present in Fennoscandian tree-ring series. On the basis of our findings, we encourage further compilation, publication, and analyses of additional wine production series containing unique biological and climatic information.

Abstract. Drought poses increasing challenges to global food production. Knowledge about the influence of drought on crop development and about the role of soil properties in drought risk analysis and mitigating drought impacts at the landscape level is important to guide climate change adaptation. Satellite earth observations can provide area-wide insights into crop growth processes that may help identify risk factors and quantify vulnerability to drought. Here, we evaluate the potential of Sentinel-2 to reveal interactions of plant-growth and soil parameters during variable weather conditions. As a case study, we assess winter wheat growth on 13 fields belonging to commercial farmers in southern Sweden in a dry year and a year with normal weather conditions. To track crop growth, green leaf area index (GLAI) was estimated from satellite imagery using a radiative transfer model. Proxies for winter wheat growth rate, peak GLAI, and the timing of peak GLAI were derived from the GLAI development at the single field level. We then compared the crop growth proxies between the two years and across the fields and related them to measured soil properties. We found a lower growth rate, lower peak GLAI and earlier peak GLAI in the dry year compared to the year with normal weather conditions. An increase in peak GLAI in the dry year was also shown to be related to a higher growth rate, and this was not shown in the year with normal precipitation. Differences in crop development between years were large for some fields but small for other fields: suggesting that soil properties play a role in crop response to drought. We found that fields with a higher amount of plant available water capacity had better crop performance in the dry year and smaller relative differences in growth rate between the two years. The observed lower growth rate, lower peak GLAI, and earlier peak in the dry year compared to the year with normal weather conditions, demonstrate that satellite imagery can be used to quantify plant-soil-weather interactions at scales relevant to commercial farming. Our investigation serves as a first step towards supporting drought risk management, drought adaptation and communication activities on this important topic.
Coupling a large-scale glacier and hydrological model (OGGM v1.5.3 and CWatM V1.08) – towards an improved representation of mountain water resources in global assessments

Published: July 2024

Abstract. Glaciers are present in many large river basins, and due to climate change, they are undergoing considerable changes in terms of area, volume, magnitude and seasonality of runoff. Although the spatial extent of glaciers is very limited in most large river basins, their role in hydrology can be substantial because glaciers store large amounts of water at varying timescales. Large-scale hydrological models are an important tool to assess climate change impacts on water resources in large river basins worldwide. Nevertheless, glaciers remain poorly represented in large-scale hydrological models. Here we present a coupling between the large-scale glacier model Open Global Glacier Model (OGGM) v1.5.3 and the large-scale hydrological model Community Water Model (CWatM) V1.08. We evaluated the improved glacier representation in the coupled model against the baseline hydrological model for four selected river basins at 5 arcmin resolution and globally at 30 arcmin resolution, focusing on future discharge projections under low- and high-emission scenarios. We find that increases in future discharge are attenuated, whereas decreases are exacerbated when glaciers are represented explicitly in the large-scale hydrological model simulations. This is explained by a projected decrease in glacier-sourced runoff in almost all basins. Calibration can compensate for lacking glacier representation in large-scale hydrological models in the past. Nevertheless, only an improved glacier representation can prevent underestimating future discharge changes, even far downstream at the outlets of large glacierized river basins. Therefore, incorporating a glacier representation into large-scale hydrological models is important for climate change impact studies, particularly when focusing on summer months or extreme years. The uncertainties in glacier-sourced runoff associated with inaccurate precipitation inputs require the continued attention and collaboration of glacier and hydrological modelling communities.
A wave-resolving 2DV Lagrangian approach to model microplastic transport in the nearshore
Authors: Jalón-Rojas Isabel , Sous Damien , Marieu Vincent
Published: July 2024

Abstract. Potentially acting as a source or a sink for plastic pollution to the open ocean, nearshore waters remain a challenging context for predicting the transport and deposition of plastic debris. In this study, we present an advanced modelling approach based on the SWASH wave model and the TrackMPD (v3.0) particle transport model to investigate the transport dynamics of floating and sinking microplastics in wave-dominated environments. This approach introduces novel features such as coupling with advanced turbulence models, simulating resuspension and bedload processes, implementing advanced settling and rising velocity formulations, and enabling parallel computation. The wave laboratory experiments conducted by Forsberg et al. (2020) were simulated to validate the model's ability to reproduce the transport of diverse microplastics (varying in density, shape, and size) along a comprehensive beach profile, capturing the whole water column. Our results underscore the robustness of the proposed model, showing good agreement with experimental data. High-density microplastics moved onshore near the bed accumulating in proximity to the wave-breaking zone, while the distribution of low-density particles varied along the coastal profile depending on the particle properties. The study also sheds light on the primary mechanisms driving microplastic transport, such as Stokes drift, wave asymmetry and settling/rising velocities. Sensitivity analyses on calibration parameters further confirm the robustness of the model results and the influence of these factors on transport patterns. This research establishes the SWASH-TrackMPD approach as a valuable tool, opening avenues for future studies to contextualize laboratory findings within the complexities of real-world nearshore environments and further refine our comprehension of microplastic dynamics across different beaches and wave-climate conditions.
A national-scale hybrid model for enhanced streamflow estimation – consolidating a physically based hydrological model with long short-term memory (LSTM) networks
Authors: Liu Jun , Koch Julian , Stisen Simon , Troldborg Lars , Schneider Raphael J. M.
Published: July 2024

Abstract. Accurate streamflow estimation is essential for effective water resource management and adapting to extreme events in the face of changing climate conditions. Hydrological models have been the conventional approach for streamflow interpolation and extrapolation in time and space for the past few decades. However, their large-scale applications have encountered challenges, including issues related to efficiency, complex parameterization, and constrained performance. Deep learning methods, such as long short-term memory (LSTM) networks, have emerged as a promising and efficient approach for large-scale streamflow estimation. In this study, we have conducted a series of experiments to identify optimal hybrid modeling schemes to consolidate physically based models with LSTM aimed at enhancing streamflow estimation in Denmark. The results show that the hybrid modeling schemes outperformed the Danish National Water Resources Model (DKM) in both gauged and ungauged basins. While the standalone LSTM rainfall–runoff model outperformed DKM in many basins, it faced challenges when predicting the streamflow in groundwater-dependent catchments. A serial hybrid modeling scheme (LSTM-q), which used DKM outputs and climate forcings as dynamic inputs for LSTM training, demonstrated higher performance. LSTM-q improved the mean Nash–Sutcliffe efficiency (NSE) by 0.22 in gauged basins and 0.12 in ungauged basins compared to DKM. Similar accuracy improvements were achieved with alternative hybrid schemes, i.e., by predicting the residuals between DKM-simulated streamflow and observations using LSTM. Moreover, the developed hybrid models enhanced the accuracy of extreme events, which encourages the integration of hybrid models within an operational forecasting framework. This study highlights the advantages of synergizing existing physically based hydrological models (PBMs) with LSTM models, and the proposed hybrid schemes hold the potential to achieve high-quality large-scale streamflow estimations.
Shaped and filled by the Rhine Glacier: the overdeepened Tannwald Basin in southwestern Germany

Published: July 2024

Abstract. The Alpine region was shaped by repeated glaciations during the Quaternary, which led to the formation of overdeepened valleys and basins. These features today, hidden below the present-day land surface, host multiple stacked and nested glacial sequences and offer valuable insight into the environmental history and geomorphological evolution of the region. The project Drilling Overdeepened Alpine Valleys (DOVE) of the International Continental Scientific Drilling Program (ICDP) is dedicated to investigating such overdeepened structures around the Alps. Within DOVE, we here focus on the Tannwald Basin in southern Germany. Situated distally within the area formerly occupied by the Rhine Glacier piedmont lobe; it was shaped by multiple glaciations, yet it is located outside the Last Glacial Maximum (LGM) ice extent. Previous seismic imaging and the presence of interglacial pollen sequences indicate a multi-phase infill history. The complex sedimentary architecture observed in a newly drilled core allows for comparison with seismic data and lithological evidence from other sites. On the basis of a lithofacies model that introduces 17 lithotypes, we propose that the basin fill is composed of three lithostratigraphic units that reflect the glacial history of the basin. After the erosion of the Tannwald Basin, a cold-climate, stacked basin-infill sequence recorded sedimentation of two glacial advances, before it was covered by LGM outwash. The sedimentary record includes an extensive basal glacial shear zone with deformed bedrock and several overlying diamict horizons. Further upcore, deformation structures underscore the role of gravitational processes as well as profound glaciotectonics, deforming the sediment deep within the subsurface. While the sedimentary record indicates a rather rapid infill of the depression, further age constraints and detailed investigations of ice-contact sediments will clarify open questions regarding the temporal classification of the deposits.
A study of sea ice topography in the Weddell and Ross seas using dual-polarimetric TanDEM-X imagery
Authors: Huang Lanqing , Hajnsek Irena
Published: July 2024

Abstract. The total freeboard, which is the ice layer above water level and includes the snow thickness, is needed to retrieve the ice thickness and ice surface topography. Single-pass interferometric synthetic aperture radar (InSAR) allows for the generation of digital elevation models (DEMs) over the drifting sea ice. However, accurate sea ice DEMs (i.e., the total freeboard) derived from InSAR are impeded due to variation in the penetration of the radar signals into the snow and ice layers. This research introduces a novel methodology for retrieving sea ice DEMs using dual-polarization interferometric SAR images, considering the variation in radar penetration bias across multiple ice types. The accuracy of the method is verified through photogrammetric measurements, demonstrating that the derived DEM has a root-mean-square error of 0.26 m over a 200 km × 19 km area. The method is further applied to broader regions in the Weddell Sea and the Ross Sea, offering new insights into the regional variations of the sea ice topography in the Antarctic. We also characterize the non-Gaussian statistical behavior of the total freeboard using log-normal and exponential-normal distributions. The results suggest that the exponential-normal distribution is superior in the thicker-sea-ice region (average total freeboard > 0.5 m), whereas the two distributions exhibit similar performance in the thinner-ice region (average total freeboard < 0.5 m). These findings offer an in-depth representation of the total freeboard and roughness in the Weddell and Ross seas. The novel methodology introduced here can be conducted on time series data to comprehend the dynamics of the sea ice, including its growth and deformation.

Abstract. Spatial epidemiology tools play a critical role in effectively allocating resources to curb the spread of animal diseases. This study focuses on classical scrapie (CS), an animal prion disease identified in Portugal, which infects small ruminant flocks and has been shown to be experimentally transmissible to wild cervids. Utilising remote sensing technologies and semi-automatic classification models, we aimed to evaluate the risk of interspecies prion transmission from domestic small ruminants to wild cervids (hosts). To achieve this, we gathered data related to hosts and infected small ruminant flocks. Furthermore, we collected and processed freely available, medium-resolution satellite imagery to derive vegetative and biophysical spectral indices capable of representing the primary habitat features. By employing a pixel-based species distribution model, we integrated the compiled geographical distribution data and spectral data with five supervised classification algorithms (random forest, classification tree analysis, artificial neural network, generalised linear model, and generalised additive model). The consensus map allowed accurate predictions of spatialised regions exhibiting spectral characteristics similar to where CS and its hosts were initially identified. By overlapping suitable territories for disease and host occurrence, we created a spatially explicit tool that assesses the risk of prion spill-over from domestic small ruminants to wild cervids. The described methodology is highly replicable and freely accessible, thus emphasising its practical utility. This study underscores the substantial contribution of model-based spatial analysis to disease monitoring and lays the groundwork for defining populations at risk and implementing targeted control and prevention strategies, thus safeguarding both animal and public health.

Published: July 2024

En el presente artículo se analiza el poblamiento de la Edad del Bronce (2150-1500 cal BC) en las cordilleras prebéticas, empleando como caso de estudio el corredor Yecla-Caudete. A partir de variables espaciales como el análisis del lugar de emplazamiento, área de captación, visibilidad, tamaño superficial y la distribución territorial de un conjunto de 33 yacimientos, se determina un patrón uniforme de ocupación del territorio entre los asentamientos de mayor tamaño y agrupado de los de menor tamaño en torno a los anteriores. Con estas características se puede inferir que las comunidades del Prebético efectuaron una ocupación plenamente organizada del territorio, asegurándose la autosostenibilidad económica y la transmisión generacional de las propiedades.

En este trabajo se presentan los resultados de la campaña de 2018 en la aldea del Hierro I del Cerro de San Vicente. El trabajo de campo conllevó una prospección previa con georradar (GPR) y la verificación de sus resultados preliminares mediante una cata de 200 m2, centrada en una segunda fase en los 64 m2 donde se centraban las anomalías. Se ha identificado una vivienda de planta circular, cuya trayectoria de uso muestra una biografía intercalada con cenizales, dos estructuras adjetivas y retazos de un edificio rectangular, datados en los siglos VII-VI a.C. La excavación de un potente cenizal ha permitido recuperar abundantes restos óseos y carpológicos que han sido estudiados por especialistas. También destaca la muestra cerámica, que presenta vajilla inciso-impresa más antigua (s. IX-VIII a.C.) y vajilla coetánea a la ocupación doméstica, tanto local a mano como importada (un fragmento de urna Cruz del Negro y otro de engobe rojo fenicio). Se plantea la hipótesis de que el sector excavado formó parte de un vecindario mayor aún no excavado. Su edilicia, la elaboración local de vajilla exótica (grafitada, de “estilo Carambolo”, imitaciones de cerámica gris o nurágica estampada), el empleo de abalorios como cuentas de fayenza, el uso de lámparas-candiles o el esgrafiado de la vajilla con grafitos no grafemáticos parecen indicar además la presencia de mujeres educadas en otras regiones ibéricas, que reproducen tales saberes procedimentales exógenos.
Agregación poblacional y cambio social en el Macalón (Nerpio, Albacete). Formación y evolución de un asentamiento complejo durante los ss. VII-V ane

Published: July 2024

En este trabajo relaciono determinados elementos arqueológicos del Macalón (Nerpio, Albacete) con cambios en la apariencia personal, la producción, el consumo y el ritual. Su análisis permite hablar de formas de distinción social y de cambios en el control de la economía, la fuerza y la ideología, cuestiones que considero claves para explicar la agregación poblacional y el funcionamiento de este asentamiento destacado a escala regional durante el Hierro antiguo. Este proceso se enmarca en el sureste peninsular, un espacio caracterizado por procesos de contacto cultural, transformación de las formas de poblamiento e interconexión de redes de intercambio suprarregionales. El fracaso de este proceso en el Macalón durante el s. V ane permite identificar un proceso de agregación que fue seguido de otro de dispersión y descentralización, señalando una evolución no lineal en este territorio.

The Gandus Camping Ground Access Road Construction Project is required to be completed on time so that consumer confidence is maintained. To achieve this, control is needed which must be known in advance through ongoing project performance. One way to determine project performance is the Earned Value method which integrates aspects of cost, time and work performance. Therefore, this Earned Value analysis is applied to the Gandus Campground Access Road Construction Project. Project performance is analyzed based on cost performance index (Cost Performance Index) and time (Schedule Performance Index). Calculations are based on planned value, earned value and actual costs. Performance control is reviewed for 8 weeks, namely week 12 to week 19. The results of the analysis in weeks 12 to 19 show that the costs incurred were greater than planned and the implementation time was longer than planned as indicated by the average value of CPI = 0.976 (CPI <1) and the average value of SPI = 0.999 (<1). The results of the estimated final project cost are IDR 3,740,377,358.49 with an implementation time of 24 weeks, which means the project will be in accordance with plan.

One of the issues in road infrastructure is traffic congestion, which leads to longer travel times for road users. Traffic congestion is a serious problem in big cities like Palembang, including around Monpera, a tourist attraction located near the city center surrounded by busy roads. Traffic involves variables such as volume, speed, and density with random variations. Therefore, it is important to study the impact of Monpera's tourism activities on traffic. The research methodology used includes surveys and observations to gather data on visitor numbers, air quality testing, and traffic volume during peak hours. The research findings indicate that the impact observed is an increase in traffic volume, especially on weekends from 8:00 AM to 12:00 PM. Based on air quality measurements around Monpera, it still meets the established environmental standards. This suggests that Monpera's activities do not have significant effects on air quality. However, the level of traffic service in this area is rated low at 0.77 indicating that traffic flow tends to be unstable

Published: July 2024

A method for calculating the broadband albedo of the Earth’s surface is proposed, which is used on the basis of two narrowband albedos calculated using signals from two AVHRR channels. It has been established that the Liang formula used to calculate the broadband albedo does not allow for the presence of an arbitrary functional relationship between the specified narrowband albedos. It is shown that the average integral value of the broadband albedo reaches a maximum value, i.e., unity, provided that one narrowband albedo is equal to unity, and the other is equal to 1.48. To eliminate this drawback, it is proposed to impose some restrictive condition on the specified relationship in the integral expression. The threshold value at which the known formula turns out to be correct is determined.

Цель исследований – изучение изменений тропосферных содержаний NO2, SO2 и CO на территории Беларуси, измеряемых с помощью космической съемки. По результатам съемки спутника Sentinel-5P TROPOMI (зима и лето 2022 года) получены усредненные концентрации над городами, особо охраняемыми природными территориями и для Беларуси в целом. Установлены значительные сезонные колебания содержаний NO2, SO2 и CO. Зимой средние и медианные концентрации SO2 выше летних в 23,77 и 17,9 раза соответственно; NO2 – в 3,35 и 2,69 раза, CO – в 1,16 и 1,17 раза. Содержание NO2 над городами выше, чем над особо охраняемыми природными территориями в 1,2 раза. В летний период наибольшие концентрации NO2 наблюдались над Гомелем, Гродно, Брестом, Минском, Речицей, Светлогорском; в зимний период – над Минском, Гомелем, Новополоцком, Витебском. Концентрации SO2 характеризуются сильной пространственно-временной изменчивостью. Концентрации SO2 и СО над городами и ООПТ близки и статистически значимо от фона не отличаются.

Роль пространства в трансформационной модели российской экономики
Authors: Гладкий Юрий Никифорович
Published: July 2024

Рассмотрены вопросы использования пространства в трансформационной модели российской экономики. Подчеркивается, что это понятие вмещает в себя значительно больше смыслов, чем обычно вкладывают в него отдельные авторы и составители официальных документов. Пространство – еще среда обитания, качество жизни, экологическое состояние, этническая родина, а также геополитические и геостратегические интересы федеративного государства. Отстаивается многомерность определения модернизации с идентификацией многих критериев, включая пространственный. Анализируется содержание стратегии пространственного развития РФ на период до 2025 года, во многом ориентированной на западные рынки. Уточнение смысла понятий «пространство» и «модернизация» сопровождается увязкой этих категорий с конкретной территорией. В связи с новой геостратегической ситуацией и реализацией идеи «Восточного поворота» привлекается внимание к процессу создания в Сибири и на Дальнем Востоке территорий опережающего развития (ТОР) для привлечения внешних инвестиций, ускоренного развития экономики и улучшения жизни населения. Географическая близость России и Китая, а также во многом совпадающие их геополитические интересы, способны стать мультипликатором эффективности такого освоения.

Published: July 2024

СМИ сегодня обеспечивают плотное транслирование оценочных суждений относительно важных национальных, региональных и международных проблем, становясь мощнейшим инструментом влияния, поэтому на их функционировании и на распространяемых при их посредничестве сообщениях всегда сосредоточено особое внимание всех социальных субъектов и прежде всего тех, кто заинтересован в оперативном решении актуальных в контексте текущей жизни задач. В современной научной практике, несмотря на интенсивно расширяющийся корпус исследований, не до конца остаются раскрытыми вопросы, связанные с особенностями становления, развития и функционирования СМИ в современных обществах разных регионов мира. Цель работы – рассмотреть СМИ Республики Мали в контексте современного, демократизирующегося общества, охарактеризовать условия, которые определяют параметры их функционирования. На основе эмпирического наблюдения за складывающейся в Республике Мали системой СМИ, отслеживания и регистрации значимых особенностей ее функционирования и анализа документов, регламентирующих ее деятельность, сделан вывод о том, что свобода СМИ в Республике Мали гарантируется сегодня как ее Конституцией, так и рядом базовых законов, принятых после 1991 года. Показано, что в результате демократических, многопартийных выборов 1991 года и проводимой в стране новой коммуникационно-информационной политики, а также связанной с ней либерализации рынка СМИ медиаландшафт Мали радикально изменился. Сделан вывод о том, что сегодня Республика Мали нуждается в создании собственной системы профессионального журналистского образования, которая обеспечит требуемый уровень профессиональной подготовки журналиста и его способность качественно отвечать на запросы современного, демократизирующегося общества. Результаты проведенного исследования вносят вклад в разработку актуальных аспектов проблемы СМИ Западной Африки в условиях стремительной социально-политической динамики.

К биологии и экологии домового (Passer domesticus (Linnaeus, 1758)) и полевого (P. montanus (Linnaeus, 1758)) воробьев в условиях города Сыктывкара (Республика Коми)
Authors: Голикова Елена Александровна , Метелькова Татьяна Сергеевна
Published: July 2024

Представлены результаты исследования некоторых аспектов биологии домового и полевого воробьев в условиях города Сыктывкара. В период с января по июнь 2021 года на территории города (S = 11,05 км2) в результате подсчета абсолютной численности зарегистрировано 1127 особей домового воробья с плотностью населения 101,9 ос./км2 и 130 особей полевого воробья с плотностью населения 11,5 ос./км2. Характер распределения птиц неравномерный. Домовый воробей преимущественно заселяет окраины города, что обусловлено сочетанием доступных источников корма, большим числом укрытий, мест для гнездования и ночлега. Полевой воробей малочисленный и, как менее синантропизированный вид, предпочитает озелененные участки центральной части города. Гнездовой период воробьев в условиях города Сыктывкара начинается в конце мая. По нашим наблюдениям, в течение периода исследований пары образовали 61,6 % птиц от общего числа особей. В зимний период рацион домового и полевого воробьев зависит от кормов антропогенного происхождения – птицы питаются на кормушках и пищевыми отходами. Весной преобладает питание растительной пищей, с началом гнездования – животной.
Deep endometriosis – diagnosis and impact on quality of life
Authors: Ivanova Elena , Codreanu Nadejda
Published: July 2024

Introduction. Deep infiltrating endometriosis (DIE) is considered the most painful form of endometriosis, responsible for reducing the women’s quality of life (QoL). Its management presents difficulties in medicine. The #Enzian classification reflects locations of DIE and simplifies its medical management. International guidelines recommend studies of QoL in women with endometriosis. Objective. To investigate the symptoms of DIE and determine its impact on QoL to optimize its diagnostics. Materials and methods. A cohort study was conducted over 2 years at the Gheorghe Paladi Municipal Clinical Hospital, including 190 patients with endometriosis, who were divided into groups: main group - 85 patients with DIE, control group - 105 other endometriosis forms. To objectify the pain, Visual Analog Scale and Biberoglu and Behrman (B&B) were used. Endometriosis was staged with the #Enzian classification. For the analysis of QoL, three standardized questionnaires were used. Data were recorded in Excel and statistically calculated with the SPSS program. Results. Pelvic pain syndrome according to the Visual Analog Scale and B&B scales in the main group was 3 times more pronounced than in the control group (p < 0.01). Lesions of DIE according to the #Enzian statistically correlated with chronic pelvic pain, dysmenorrhea, dyspareunia, dysuria, dyschezia >7 points (VAS), catamenial rectal tenesmus, defecation disorders, menometrorrhagia, hematuria, bladder tenesmus, hydronephrosis with ureteral stenting during pregnancy, catamenial cough and hemoptysis, chest pain and spontaneous pneumothorax, hemorrhagic scar, hiccups, and the frenicus symptom (p < 0.05). According to the questionnaires of QoL, DIE significantly influences life determinants by 44.27%, compared to the control group at 3.64% (p < 0.01), allowing realization of life determinants in a maximum of 58.54% vs. the control group’s 92.18% (p < 0.01). Additionally, psychological well-being in patients with DIE is lower than that in the control group (44.29% vs. 81.38%, p < 0.01). Conclusions. High-intensity pain syndrome and extragenital symptoms correlated with compartments of #Enzian will assist in the preoperative multidisciplinary diagnosis of DIE. The high influence on life determinants, the low realization of life potential, and the low psychological well-being confirm the significant impact of DIE on QoL, classifying it as a disability.
Scrutinizing prognostic scores’ effectiveness in non-Hodgkin’s lymphomas with primary lymph node involvement
Authors: Tomacinschii Victor
Published: July 2024

Introduction. Non-Hodgkin lymphoma (NHL) encompasses a diverse group of malignancies arising from malignant proliferation of lymphocytes, each subtype characterized by unique epidemiological, etiological, and clinical features. Prognostication is essential for guiding treatment decisions and improving patient outcomes. Prognostic scores, including traditional and molecular systems, offer insights into survival prediction. The aim of the present study was to evaluate the applicability of traditional prognostic scores based on clinical markers and laboratory biomarkers in predicting the outcomes of patients with primary nodal NHL. Materials and methods. This study included 78 NHL patients treated at the Chisinau Oncological Institute from 2017 to 2021. Clinical and biological data were collected, and the following prognostic scores were calculated: International Prognostic Index (IPI), The combined index of hemoglobin, albumin, lymphocyte, and platelet (HALP score), Platelet to Lymphocyte Ratio (PLR), Neutrophil to Lymphocyte Ratio (NLR), Albumin/Globulin ratio (AG), and Charlson comorbidity index (CCI). Statistical analyses, including descriptive statistics, ROC curve analysis, and Kaplan-Meier survival curves, were conducted. Results. Of the patients, 40 (51.2%) were female, with a mean age of 57.1 ± 10.2 years. Peripheral lymph nodes were predominantly affected (84.6%), with diffuse large B-cell lymphoma being the most prevalent subtype (59.0%). Prognostic scores, including the International Prognostic Index (IPI), Hemoglobin, Albumin, Lymphocyte, and Platelet (HALP) score, and Charlson Comorbidity Index (CCI), demonstrated varying levels of discriminatory ability in predicting overall survival (OS). Notably, the HALP score (AUC = 0.650; p = 0.026), IPI (AUC = 0.745; p = 0.0002), and CCI (AUC = 0.636; p = 0.043) were statistically significant predictors of OS. Conclusions. Traditional prognostic scores (IPI. HALP score, CCI) offer valuable prognostic information for NHL patients. Further research is needed to validate these findings and explore cost-effective prognostic strategies.
