Spatio-temporal relationship of short-term renewable energy forecast errors
Authors: Zech Matthias , Schroedter-Homscheidt Marion , von Bremen Lueder
Published: July 2023

Climate-neutral societies rely on large-scale renewable energy expansion. With increasing renewable energy capacities, the impact of renewable energy forecasts errors on energy systems magnifies which strengthens the need to better understand and describe them. Renewable energy forecast errors are particularly interesting when studied in their spatiotemporal domain: Uncorrelated or even negatively correlated forecast errors can get smoothed out reducing the regional impact of forecast errors whereas correlated renewable energy forecast errors can result into largescale deviations between plannable and dispatchable renewable energy which can affect the entire energy system. Despite its importance, an analysis of the spatio-temporal characteristics of short-term renewable energy forecast errors is still lacking. This study aims to close this gap by studying the spatio-temporal characteristics of short-term (1 to 3 days forecast lead time) renewable energy NWP (ECMWF IFS HRES) forecast errors in Europe. The spatio-temporal relationship is described by deriving characteristic correlation lengths for each site whereas the effect of smoothing is calculated through the analysis of spatially convoluted forecast errors. We show that solar and wind energy forecast errors have fundamentally different behavior subject to site characteristics and forecast lead times. Furthermore, we identify regions which are prone to forecast smoothing or accumulation. Lastly, we illustrate that accumulated forecast errors for actual renewable sites in Europe are uncorrelated over large distances, yet forecast error clusters can be identified for wind and solar energy. This is particularly crucial for the case of planned wind offshore farms as we show for the EU wind offshore expansion plans until 2030.

Published: July 2023

Advances in impact modelling and numerical weather forecasting have allowed accurate drought monitoring and skillful forecasts that can drive decisions at the regional scale. State-of-the-art drought early warning systems are currently based on statistical drought indicators, which do not account for regional vulnerabilities, and hence neglect the socio-economic impact for initiating actions. The transition from conventional physical forecasts of droughts towards impact-based forecasting (IbF) is a recent paradigm shift in early warning services, to ultimately bridge the gap between science and action. The demand to generate predictions of “what the weather will do” underpins the rising interest in drought IbF across all weather-sensitive sectors. Despite the socio-economic benefits are expected to be high, migrating to this new paradigm presents myriad challenges. In this paper, we outline the progress in IbF of drought, and present a road map highlighting current challenges and corresponding needs for advancing this emerging field. More specifically, we identify the main disconnects and biases of the science and practice of IbF of drought, namely contextual bias (inadequate accounting for the spatio-sectoral dynamics of vulnerability and exposure), data bias (mainly textual and lacking collection protocols for all sectors), model bias (mostly reliant on machine learning models), sectoral bias (mainly agriculture in the science), and geography (mainly Europe for the science, and developing regions in the practice). Our vision is to facilitate the IbF progress and its use in making informed and timely decisions on mitigation measures, thus minimizing the impacts of droughts globally.           
Is it possible to identify flash flood risk areas with global model rainfall forecasts? A comparative study for the ECMWF ensemble - raw model versus a point-scale post-processed version.
Authors: Pillosu Fatima , Prudhomme Christel , Cloke Hannah
Published: July 2023

Flash floods are one of the most devastating natural hazards. They can occur in very large or small rural or urban areas, with little to no warning. Extreme (localized) rainfall plays a crucial role.  

This presentation compares the rainfall forecast performance, for the raw ECMWF ensemble (ENS) and post-processed point-scale output derived from that (ecPoint), in pinpointing areas at risk of flash floods. Performance evaluation is based on location and timing accuracy for the flash floods. Long-term objective verification and case studies are used to compare.

Although ENS effectively identifies areas at flash flood risk in instances of large-scale rainfall, its performance falters when confronted with localized extreme convective systems. We show how ecPoint yields superior results for both scenarios, pinpointing well areas at flash flood risk up to medium-range timescales. This enables decision-makers to extend their preparedness and action time window. 

This presentation will also demonstrate forecast system strengths and weaknesses, and how forecasters can leverage these to produce better predictions of areas at flash flood risk up to medium-range lead times.
Climate and Human Health

Published: July 2023

The climate is an essential factor for human bio-comfort and health. Since ancient times, people have used the climate's resources for their health, but at the same time, they have sought ways to cope with climate hazards. Nowadays, bioclimatic issues are gaining even greater importance, given the drastic increase in extreme climate events. There is a growing need for a deeper understanding of these events, the ways and mechanisms by which they affect the biostatus of the human organism, as well as the ways to deal with this problem at the individual and societal level. This report examines the main bioclimatic hazards in Bulgaria and their possible direct and indirect effects on human health. Direct are the effects of heat waves and ice episodes, intense precipitation and floods, strong winds, storms, avalanches, UV radiation overdoses, and contrasting weather changes. On the other hand, weather and climate indirectly affect our health through their influence on the air we breathe, the water we drink, the food we consume, and the ecosystems that surround us. The report also comments on some climate-sensitive diseases – respiratory, cardiovascular, and infectious (borne by water, food, air, and vectors). Socio-economic parameters of the society and of the individual have an important bearing on the intensity and number of these climate-related health consequences. Here they are considered as an index of health vulnerability in the country tracked for the period 1995-2020. On the other hand, this report also pays attention to the country's bioclimatic resources, with a view to using them to optimize human health. These are solar, thermal, air, wind, and cryogenic resources.The utilization of bioclimatic resources and dealing with bioclimatic hazards in Bulgaria are issues embedded in a number of state policies at the national and local level. This report sheds light on the main goals, priorities, and measures set out in the National Strategy for Adaptation to Climate Change.

Weather, winter severity, Danube floods and low flows at Bratislava in 1435-1595:analysis of daily/weekly resolution weather data in the Bratislava town accounts
Authors: Kiss Andrea
Published: July 2023

Written mainly in German and partly in Latin, the town or chamberlain accounts of historical Pozsony/Pressburg (present-day Bratislava), almost continuously available between 1434-1435 and 1595, contain daily/weekly resolution data on Danube floods, snow and ice cover and occasional data on rainfall, strong winds, (unintentional) fires, cold days and low flows of the Danube. The source provides systematic, annual accounts of incomes and expenses, with only a few years missing: flood and weather related reports were mainly included in the bridge masters’, the ice-cutters’, the ferrymen’s, the town messengers’, and the road and wall maintenance accounts. Furthermore, weather and water-level related information occasionally was also identified in other sections of the accounts, regarding smaller bridges, river transportation, fishing, meadows and hayfields, woods, and other utilities of the nearby island area. Because of the high density of weather and flood data and the available (mainly qualitative) descriptions, it is possible to present a three-scaled index-based quantitative reconstruction of Danube floods and, for some of the years, index reconstructions of winter severity, temperature and precipitation (rainfall, snowfall).
In the presentation, the following major topics are addressed:

reconstruction of Danube flood intensity (three-scaled), seasonality, and flood types;
(annual, seasonal) number of intensive rainfall and snowfall events and the (three-scaled) precipitation intensity reconstruction;
temperature reconstruction, based on three-scaled intensity indices – primarily related to winter;
weather extremes and corresponding hazards: strong winds and storms, (unintentional) fires, torrential rains (resulting mass erosion);
documented Danube low-flow events, mainly reflecting on prolonged dry periods in the Upper-Danube catchment.

In the final part of the presentation, long-term climate variability processes are discussed in brief. With applying additional information available in the Bratislava area in other contemporary sources such as charters, letters, a diary (of Zsigmond Torda) and other narratives, it is possible to define periods richer in floods, hard winters and reported extreme events. Apart from the period of the early Spörer solar minimum (1430s-1440s), anomalous periods are identified around the turn of the 15th and 16th centuries (ca. 1480s-1510s), in the mid- and late 16th century.
On the way to adjust standards to future climate
Authors: Schlünzen K. Heinke , Froehling Catharina , Vondran Johanna
Published: July 2023

Climate change is one of the greatest challenges of our time. Despite all scientific findings on climate change, the current measures to reduce GHG emissions are too small to keep the global warming well below 2 K, preferably at 1.5 K.  “Policies currently in place point to a 2.8°C temperature rise by the end of the century.” [1] Therefore, in addition to measures for climate protection, strategies and measures for adaptation to climate change are needed to mitigate the consequences of climate change and avert damage.
To date, planning decisions, e.g., infrastructure, urban and regional planning, take into account the climate of the past in the relevant standards. In fact, today’s planning often has an impact over several decades and cannot be easily corrected (e.g., railroad embankments, sewage systems). Thus, the climate relevant to the lifetime of the planning realisation must be considered in standards to minimize damage caused by future climate. This is also true for existing infrastructure that has to be adapted to future climate (e.g., depth of water pipes; higher ground temperatures needing more chlorination for sanitary reasons). To facilitate the adjustment to a changing climate for the user of standards and perform adaptation without expert knowledge on climate, the Association of German Engineers (VDI) has decided to review existing standards and standards in progress with regard to climate resilience.[2] The aim is to modify standards, if necessary, by including the climate relevant for the lifetime of the planning realisation. This sounds simple, but a number of questions has to be answered: “To which climate change do we need to adapt?”, “What is the lifetime of a planning realisation?”, “Which climate changes are relevant for this standard?”. The approach followed by VDI and some example answers are given.

Southern Ocean polar cyclones drive extreme atmospheric anomalies over Antarctic sea ice
Authors: Messori Gabriele , Hepworth Ehlke , Vichi Marcello
Published: July 2023

High-latitude cyclones in the Southern Ocean can reach and shape the Antarctic sea-ice. Rare in-situ measurements from a winter cyclone in the marginal ice zone evidence how it caused both significant wave activity and large atmospheric temperature and moisture anomalies. We investigate here with the help of reanalysis data, whether cyclones may routinely lead to the presence of unusually warm, moist air masses over ice-covered regions in the Southern Ocean. We find that extreme atmospheric anomalies over sea ice often occur in the absence of cyclones, and that intense cyclones have a stronger association with extreme temperature anomalies than extreme moisture anomalies. This points to a nuanced link between high-latitude Southern Ocean cyclones and atmospheric anomalies over Antarctic sea ice.  We next consider whether cyclones may also lead to variability in winter Antarctic sea-ice concentration. We characterise sea-ice variability and cyclone activity in different Southern Ocean sectors using atmospheric reanalyses and a cyclone-tracking algorithm, and then quantify the proportion of extreme sea-ice variability engendered by cyclones of different intensity. We conclude that there is a significant link between variability in winter sea-ice concentration and: (1) all cyclones in the Ross/Amundsen sector; (2) all but the weakest cyclones in the King Haakon VII, East Antarctic, and Bellinghausen sectors; and (3) all but the most intense cyclones in the Weddell sector. More generally, up to 40% of episodes of extreme sea-ice variability are caused by extratropical cyclones within all regions apart from the Weddell sector, (where extreme sea-ice variability is less connected to the fewer intense cyclones and more to the weaker cyclones).
Potential Sources of Methane Emissions in Urban Areas
Authors: Hmoudah Mustafa , Baciu Călin , Pop Cristian
Published: July 2023

Methane, a potent greenhouse gas with a relatively short atmospheric lifetime and the potential for rapid, targeted abatement, is gaining importance for near-term climate action.
Despite that Urban Areas cover <2% of the Earth’s surface, they are responsible for either anthropogenic or natural a large fraction of CH4 emissions from different types of sources. Urban Areas are responsible for a large fraction of GHG emissions (30 to 40% of global anthropogenic emissions), including methane from the different types of sources.
Usually, urban studies are generally focused on gas leaks from natural gas networks, domestic networks, combustion systems, landfills, wastewater (sewer systems) and road transport.
However, CH4 emissions have a high degree of uncertainty and aquatic systems in Urban Areas are generally neglected in the literature. Also, the Romanian national GHG inventory does not report Urban Areas emissions of CH4.
Our study is a preliminary identification of urban sources for CH4 emissions in Cluj-Napoca, the second most populous city in Romania, based on a simple detection of gas leaks, CH4 content in aquatic systems.
Tunable Diode Laser Absorption Spectroscopy (TDLAS) with resolution of 0.1 ppmv were used to determine the atmospheric concentrations of gas at different points of potential sources of CH4 around the city. Also, gas from water samples was analyzed via head-space extraction and the CH4 laser sensor of TDLAS.
This study has revealed that more than 76% of the natural gas distribution points and more than 39% sewer man-holes have values higher than the estimated background. All water samples are almost over-saturated with CH4, which means that the aquatic ecosystems represent a potential source of CH4 fluxes into the atmosphere.
These results indicate that flux measurements and sources attribution of CH4 are required for further investigation of all CH4-bearing systems.
Climate change and Desert Dust Storms in Cyprus
Authors: Chrysanthou Andreas
Published: July 2023

The Eastern Mediterranean region is already experiencing the first results of climate change, as a highly vulnerable area to climate change. Latest reports indicate and highlight the strong impact of climate change across the Eastern Mediterranean area through increased average temperatures, reduced precipitation and recurrent dust storms of higher frequency and intensity.  In the decade 1998-2008, the frequency of dust storms in Cyprus has risen with an average pace of approximately 2 extra dust days per year. Since then, this trend persists, leading to an extended and annual increasing dust event period a year. 
The Cyprus Department of Meteorology adopts new services, tools and products. Evaluating and reviewing the available forecasting tools and techniques and upgrading partnerships with research institutes, universities and organizations across the Eastern Mediterranean region, were important steps in adjusting to the rapidly changing climate parameters and climate change results in the area of Cyprus.  Since 2017, the Cyprus Department of Meteorology supports the development and the implementation of a climate change adaptation strategy to dust storm events across the Eastern Mediterranean area through the LIFE project ‘MEDEA’ (Mitigating the Health Effects of Desert Dust Storms Using Exposure-Reduction Approaches), funded by the European Union.   
The Department of Meteorology (DoM) is the Authority responsible for all the issues concerning the weather and climate. Its mission is to collect and provide information related to weather and climate for all economic and social activities of the country in order to achieve high quality of services, the general welfare of the public and the protection of life and property of its citizens. In order to achieve these, the DoM runs its own numerical weather forecasting models and operates an extensive network of meteorological stations, consisting of 51 Automatic Weather Stations (A.W.S.), 77 conventional Rainfall stations, 12 conventional Climatological and 3 Synoptic stations. Synoptic stations have stuff from the DoM carrying out regular weather observations. At the station of Athalassa upper air observations are also carried out with daily radiosonde launches. Data from the A.W.S., are collected using telemetry in almost real time and are stored in the DoM’s database.
Scale separation diagnostics and the Symmetric Bounded Efficiency for the inter-comparison of precipitation reanalyses
Authors: Casati Barbara , Lussana Cristian , Crespi Alice
Published: July 2023

Global reanalyses are routinely used to assess the state of the climate and to evaluate the ongoing climate change. The ERA5 global reanalysis has been compared against a high-resolution regional reanalysis (COSMO-REA6) by means of scale-separation diagnostics based on 2d Haar discrete wavelet transforms. Validation and inter-comparison of reanalysis products lead to a better understanding of their strengths and weaknesses, for a more robust interpretation of climate studies.
The presented method builds upon existing methods and enables the assessment of bias, error and skill for individual spatial scales, separately.  The energy scale-separation verification diagnostics (square-root energy, energy percentages, and their normalized bias) enable to assess the bias across the scales and differences in the scale structure of the reanalysis products.
A new skill score (evaluated against random chance) and the Symmetric Bounded Efficiency are introduced. These are compared to the Nash-Sutcliffe and the Kling-Gupta Efficiencies, evaluated on different scales, and the benefits of symmetric statistics are illustrated. We illustrate the enhanced diagnostic capabilities of the introduced scale-separation diagnostics while comparing ERA5 control and ensemble members to COSMO-REA6 precipitation reanalyses. Furthermore, the Symmetric Bounded Efficiency enables the comparison of gridded datasets with different resolutions, without penalizing the -more noisy- finer resolution products.
As expected, the wavelet statistics show that the coarser resolution ERA5 products underestimate small-to-medium scale precipitation compared to COSMO-REA6. The newly introduced skill score shows that the ERA5 control member, despite its higher variability, exhibits better skill in representing small-to-medium scales with respect to the smoother ensemble members. The Symmetric Bounded Efficiency is suitable for the inter-comparison of reanalyses, since it is invariant with respect to the order of comparison.
Scale-dependent Temporal Variability of the Clear-Sky Index and its Relevance for Solar Radiation Forecasts
Authors: Carpentieri Alberto , Folini Doris , Wild Martin , Meyer Angela
Published: July 2023

Solar radiation forecasting is essential for the efficient operation of solar energy plants. Accurate forecasting models can help optimize solar energy use, reduce costs, and minimize environmental impacts. The clear-sky index (CSI) is a common parameter used in forecasting models to estimate the amount of solar radiation reaching the Earth's surface. CSI is the ratio between surface solar radiation (SSR) and surface solar radiation in a clear sky situation (SSRcs). The temporal variability of CSI is scale-dependent, meaning that the evolution of CSI is less predictable at smaller spatial scales than at larger scales. This variability can strongly impact the accuracy and quality of solar radiation forecasts.
Our study aims to investigate the temporal variability of CSI at different spatial scales (from 0.02˚ to 2˚) and its possible application to SSR forecasting models. The study uses cloudiness maps estimated from Meteosat SEVIRI Level 1.5 data by the HelioMont algorithm (Castelli et al., 2014) with a spatial resolution of 0.02˚ and a temporal resolution of 15 minutes over Switzerland. To quantify the temporal variability of CSI as a function of spatial scale, we draw on methods used by Venugopal et al., 1999 and Pulkkinen et al., 2019 for precipitation analysis.
We show that the temporal variability of CSI is indeed scale-dependent, with smaller spatial scales (down to ~0.02˚) exhibiting higher temporal variability than larger scales (up to ~2˚). We also show that Fourier decomposing the CSI field in space can help to track the different temporal evolutions for the different spatial scales. This finding is particularly important for the development of more accurate forecasting models, as it suggests that different models (or at least scale-dependent parameter values) may be required for different spatial scales.
In conclusion, this study provides valuable insights into the temporal variability of CSI at different spatial scales providing experimental correlation between the spatial scale and the variability of CSI's temporal evolution. The findings of this study have important implications for the development of more accurate forecasting models, which can ultimately contribute to the increased use of solar energy sources.
Consistent picture of the horizontal circulation of the Atlantic Ocean over 3 decades
Authors: Caínzos Verónica , Pérez-Hernández M. Dolores , Santana-Toscano Daniel , Arumí-Planas Cristina , Hernández-Guerra Alonso
Published: July 2023

Abstract. The circulation in the Atlantic Ocean is marked by the complex
system of pathways of the Atlantic Meridional Overturning Circulation
(AMOC). These currents change meridionally due to the interaction with
nearby water masses. Hydrographic data provide the opportunity to
characterize these currents for the whole water column with high-resolution
data over the last 30 years. Moreover, inverse methods enable the
quantification of absolute zonal transports across these sections,
determining the strength of each current at a certain latitude in terms of
mass, heat, and freshwater, as well as their transport-weighted temperature
and salinity. Generally, no changes can be found among decades for each of
the currents in terms of transport or their properties. In the South
Atlantic, the circulation describes the subtropical gyre affected by several
recirculations. There are nearly 61 Sv entering from the Southern and Indian
oceans at 45∘ S. The South Atlantic subtropical gyre exports
17.0 ± 1.2 Sv and around 1 PW northward via the North Brazil Current,
as well as −55 Sv southward at 45∘ S into the Antarctic Circumpolar
Current. In the North Atlantic, most of the transport is advected northward
via the western boundary currents, which reduce their strength as they take
part in convection processes in the subpolar North Atlantic, also reflected
in the northward progress of mass and heat transport. Deep layers carry
waters southward along the western boundary, maintaining similar values of
mass and heat transport until the separation into an eastern branch crossing
the mid-Atlantic Ridge in the South Atlantic. Abyssal waters originating in
the Southern Ocean are distributed along the South Atlantic mainly through its
western subbasin, flowing northward up to 24.5∘ N, subjected to an
increasing trend in their temperature with time.
Global variability of high-nutrient low-chlorophyll regions using neural networks and wavelet coherence analysis

Published: July 2023

Abstract. We examine 20 years of monthly global ocean color data and
modeling outputs of nutrients using self-organizing map (SOM) analysis to
identify characteristic spatial and temporal patterns of high-nutrient low-chlorophyll (HNLC) regions and their association with different climate
modes. The global nitrate-to-chlorophyll ratio threshold of
NO3 : Chl > 17 (mmol NO3 mg Chl−1) is estimated to be a good indicator
of the distribution limit of this unproductive biome that, on average,
covers 92 × 106 km2 (∼ 25 % of the ocean). The
trends in satellite-derived surface chlorophyll (0.6 ± 0.4 % yr−1 to 2 ± 0.4 % yr−1) suggest that HNLC regions in polar and subpolar areas
have experienced an increase in phytoplankton biomass over the last decades,
but much of this variation, particularly in the Southern Ocean, is produced
by a climate-driven transition in 2009–2010. Indeed, since 2010, the extent
of the HNLC zones has decreased at the poles (up to 8 %) and slightly
increased at the Equator (< 0.5 %). Our study finds that
chlorophyll variations in HNLC regions respond to major climate variability
signals such as the El Niño–Southern Oscillation (ENSO) and Meridional
Overturning Circulation (MOC) at both short (2–4 years) and long (decadal)
timescales. These results suggest global coupling in the functioning of
distant biogeochemical regions.

Millî Eğitim Kurumlarında Sonuç Odaklıdan Süreç Odaklıya Disiplin Problemlerine Yönelik Çözümleyici Yaklaşımların Geliştirilmesi
Authors: Söylemez Erdoğan
Published: July 2023

In this study, it is aimed to develop analytical approaches for disciplinary problems from result-oriented to process-oriented in national educational institutions. There are quite a variety of opinions about the concept of discipline. The word discipline contains a feeling far from positive emotion within its structure. For this reason, it is often perceived as a word that offends students within the school boundaries. However, it should be remembered that ensuring discipline in schools is important for the safety of both students and teachers. In order to achieve the goals in schools, it is essential to create an efficient education and training area and process as a priority. The relevant educational environment, on the other hand, can be created with a safe and orderly, that is, disciplined teaching space. It should be known that the discipline within the school boundaries in this area does not mean the creation of areas that cannot be moved literally, the drawing of boundaries for students and teachers. Ensuring such a safe environment is possible only with the provision of discipline. Supported by the Ministry of National Education, this idea has been stated that the main goals of the Ministry of National Education begin primarily with the creation of a disciplined classroom environment for an efficient and effective education. However, the existence of opinions in the literature that are contrary to the relevant opinion cannot be denied. According to scientists who stated that the words class and discipline are two words that are opposite to each other, it has been emphasized that class cannot be real in an environment where discipline exists. These scientists have stated that what should happen in the classroom environment is order, not discipline, and order will be ensured if actions are linked to certain rules. According to another view, discipline when viewed from the teacher's window is a form of pressure-punishment-based behavior applied by teachers to students and other teachers, while when viewed from the student's window, it is a form of behavior that limits students' own lives and is directed at themselves. Discipline is also a requirement for people to live together. In summary, discipline is a concept that literally outweighs the quality of compliance with predetermined rules, but in terms of inclusiveness, it is a concept that includes both the student and the teacher within the limits of compliance with the rules. At the same time, it is a concept that allows the student to develop behaviors that will not create unrest in accordance with the living conditions of the society in which the student is located thanks to discipline, and provides environments that can control this negativity experienced under the relevant conditions when otherwise.

Long noncoding RNAs (lncRNAs) are considered crucial molecules associated with the tumor microenvironment (TME) and tumor immune microenvironment (TIM). Macrophages are important members of the immune system, and M1 macrophage function-associated lncRNAs still need to be further investigated. In this study, a lncRNA signature was constructed based on transcriptome differences between high and low M1 macrophage infiltration cohorts. This lncRNA signature included seven lncRNAs: LINC01494, ZDHHC20-IT1, LINC01450, LINC00871, EVX1-AS, KIF25-AS and AADACL2-AS1, and all of them were upregulated in patients lacking M1 macrophages, indicating their roles in inhibiting macrophage infiltration and polarizing to the M1 subtype, leading to an immune exclusion TME, which has been demonstrated to be closely correlated with poor prognosis. This lncRNA signature not only predicted undesirable clinical outcomes but was also associated with the immunosuppressive environment of the tumor region, which is mediated by hindering antigen presentation and processing progress. In addition, the predictive value of this lncRNA signature for immune checkpoint inhibition (ICI) therapy was also evaluated, which further enriched and strengthened the power of lncRNAs in predicting the immunotherapy response rate.

The ribosome is a large biomolecular complex responsible for protein synthesis. In Escherichia coli (E. coli), a complete ribosome is composed of a 30S small subunit and a 50S large subunit. For approximately half a century, the 30S subunit has been a key model system for studying the in vitro assembly of the ribosome, and an assembly map has been proposed. However, structural details in the assembly of this protein‒RNA complex remain elusive. In this paper, we conducted a series of coarse-grained simulations following the order of the assembly map to investigate conformational dynamics during the assembly process of the 30S subunit. It has been found that the tertiary structure of naked 16S rRNA is very unstable, which is the case after binding of early-assembly proteins. The mid-assembly proteins can significantly restrict the mobility of the 16S rRNA and make the latter close to the native structure. The final binding of the late-assembly proteins would fully obtain the collective motion of the 16S rRNA. In particular, proteins S9 and S3 may have more important contributions to the assembly of the 30S subunit than other S proteins. Our strategy of coarse-grained simulations can be generally used to study assembly dynamics of large biomolecular complexes as long as the assembly map is available.

Published: July 2023

O Brasil possui uma faixa diagonal onde ocorrem os maiores valores de irradiação, chamado cinturão solar e estendendo-se do Nordeste ao Centro-Oeste. Porém, é na região Nordeste que os melhores resultados se destacam, apresentando uma radiação solar global média de 5,9 Kwh/m², destacando-se em especialmente o Cariri Paraibano, que tem irradiação de mais de 2.800 horas por ano. Com isso, o aproveitamento desta fonte de energia limpa e renovável tem sido usada no desenvolvimento tecnológico de modo sustentável, em especial, na secagem de produtos agrícolas. Umas das tecnologias alternativas, de baixo custo e fácil manutenção, para secagem de produtos agrícolas é a utilização de secador solar. Por outro lado, técnicas de conservação inadequadas e condições precárias de armazenamento levam à deterioração da qualidade dos produtos agrícolas. Diante do exposto, este trabalho propõe o desenvolvimento de um secador solar indireto ativo para a secagem de produtos agrícolas, utilizando alguns materiais reaproveitados. Um sistema de automação com Arduino e sensores foi utilizado para leitura de temperatura e umidade relativa do ar no interior do secador. Os resultados experimentais mostraram que o coletor solar proposto foi capaz de elevar a temperatura no interior do secador em cerca de 34,4 °C, indicando que o secador solar construído pode ser utilizado na secagem de produtos agrícolas, agregando valor aos produtos e, consequentemente, melhorando a qualidade de vida das famílias dos agricultores envolvidos na atividade.

Purpose: Recently, quantitative dermatoglyphic examinations have been intensively carried out for screening purposes in oncology. Material/Methods: The present study covered 82 women aged between 36 and 80 years with clinically, histologically and mammographically confirmed breast cancer and 60 healthy women aged between 31 and 79 years from the region of Varna, Bulgaria. Two dermatoglyphic methods were applied: i) dactyloscopy of finger ridge count and finger indexes and ii) palmoscopy - palmar ridge count, palmar maximal atd, adt and dat angles, and palmar main lines. Statistical data processing was performed by means of variation analysis, regression analysis, χ2 test and one-way ANOVA using the SPSS software package, version 19. Results: The results from the dactyloscopic and palmoscopic examinations revealed several statistically significant differences in these quantitative dermatoglyphic patterns between breast cancer females and healthy ones. Conclusion: We could conclude that the purposeful examinations of the quantitative dactyloscopic patterns such as total finger ridge count and finger indexes and quantitative palmoscopic traits such as palmar ridge count, maximal adt, atd and dat angles and main palmar lines play a promising role for the cost-effective and trustworthy breast cancer screening in Bulgaria.
