This article focuses on the development of a consensus algorithm for a sharded distributed system to be used in machine-to-machine infrastructure. The authors analyze the existing advantages and disadvantages of distributed systems and sharding, as well as describe the properties that a consensus algorithm should possess, and consider various analogues. Different communication models in distributed systems are also considered: synchronous, asynchronous, and partially synchronous. The article proposes a consensus algorithm that assumes a partially synchronous message delivery environment and direct message exchange between nodes. The presented algorithm ensures convergence, integrity and consistency of data, as well as fault tolerance and high scalability. The algorithm describes the use of a standard format of unique identifiers to describe nodes, hash functions to describe the state of the consensus round, and message exchange between shards for node coordination. It also uses a pseudorandom permutation function to order operations within a single round, which allows saving on network delays and reducing the time for overall consensus on operations. In conclusion, the results of system performance measurements are shown, and general findings about the operability of the presented algorithm are given.

Published: January 2025

An important component of an electric motorcycle is the battery, which plays a role in storing energy through the principles of electrochemistry. Lead-acid and lithium-ion batteries are the two most common types of batteries found in electric vehicles. Electric motorcycle batteries typically range from 32 to 72 volts, depending on engine requirements, and have a storage capacity of 20 to 50 Ah. Batteries generally have internal resistance that causes temperature increases, which means that working at high temperatures will significantly decrease their life. Increased temperatures can also create heat leaks inside the battery, which can lead to major safety issues such as fires and explosions, as well as a loss of battery capacity. The working temperature should not be kept above 50 °C, whereas on lithium-ion batteries, it ranges between -30 °C and 40 °C. The aim of this research is to develop, manufacture, and test battery boxes with passive cooling to keep the battery temperature at the intended ideal level. The method applied is to set up a control system that can function to prevent overheating the battery. Based on the tests carried out on the passive cooling system, this managed to maintain the temperature of the lithium-ion battery when used at an average speed of 40–60 km/h.

Exploratory Tool for Radiation Exposure from Spaceflight: Rad-Bio-App
Authors: Ghosh Dr Debopriya , Verma Dr Ekta , Kumar Ghosh Mr. Romel , Anderson Dr. Tim
Published: January 2025

Spaceflight concurrently subjects biology to a variety of different stressors in addition to microgravity. For instance, ionising radiation conditions that organisms encounter in space differ significantly from those they typically encounter on Earth in terms of both quality and quantity. However, accessing and comprehending data on radiation exposure during space missions is sometimes difficult, which hinders research into how radiation affects organisms in the particular context of spaceflight. We created the Rad-Bio-App to aid with this problem. The user may examine these experiments both in terms of their radiation exposure and via their other metadata and outcomes using this web-accessible database, which imports radiation metadata from experiments preserved in NASA's GeneLab data repository. In order to help radiation biologists and non-specialist researchers view and comprehend the effects of ionising radiation on diverse biological systems in the context of spaceflight, Rad-Bio-App offers an intuitive, graphically driven environment.

Authors: Kumar Dinesh , Gupta Mukulesh , Chandra Kumar Praful , Awasthi Rajiv , Pandey Arun , Gupta Nitin Ranjan , Agarwal Vivek , Ahuja Kriti , Gupta Tuhina , Lachhwani Harshita
Published: January 2025

Aim: The present study was conducted to evaluate the corelation between Fibrosis-4 score (FIB-4) in cases of Liver fibrosis as well as Liver steatosis in comparison to other liver fibrosis assessment scores.
Methodology: Cross-sectional study was conducted amongst 352 participants who had type 2 diabetes mellitus (T2DM). FIB-4 score and Non-alcoholic fatty liver disease fibrosis score (NFS) were calculated using blood parameters and Liver Stiffness Measurement (LSM) scores along with Controlled attenuation parameter (CAP) scores were calculated using Vibration Controlled Transient Elastography (VCTE). Spearman’s correlation estimates were used to evaluate these fibrosis scores of FIB-4, NFS and LSM in Metabolic dysfunction associated steatotic liver disease (MASLD) patients.
Results: Out of a total cohort of 352 persons, 75% had steatosis and 27.1% had fibrosis based on the findings of VCTE. According to prediction based on FIB- 4, 10.8% had fibrosis, and based on the NFS fibrosis score 23.4% had fibrosis. Our data revealed a positive correlation between the FIB-4 score and LSM by VCTE (r = 0.22, p < 0.001).
Conclusion: Beyond its risk assessment, FIB-4 serves as a prognostic biomarker with clinical significance. This straightforward scoring system can act as an early warning signal, helping to identify patients who are at risk for advanced liver fibrosis and may need referral to specialized medical care.
Normal Pressure Glaucoma and CSF Compartmentalization Syndrome (About 3 Cases)
Authors: Boui Hatim , Zineb Filali , Fouad El Asri
Published: January 2025

Normal tention glaucoma and idiopathic intracranial hypertension have common characteristics, but do not clinically associate.
The physiopathological hypotheses seem to incriminate for these two pathologies a disorder of the dynamics of the cerebrospinal fluid. New data suggest that the cerebrospinal fluid that fills the spaces around the optic nerve has a composition and clean hydraulics, sometimes independent of those of other spaces of the central nervous system.
This pathological compartmentalization of the optic nerve sheath was assumed in both idiopathic intracranial hypertension and normal pressure glaucoma. The subject of this thesis enriches the literature on NTG with observations illustrating the coexistence of a NTG and compartmental syndrome documented by imaging. A review of the literature on this association is summarized in the discussion.
The present work is a retrospective study of 3 patient files presenting both "idiopathic intracranial hypertension" and "normal pressure glaucoma", whose clinical and paraclinical data were collected from patients' files collected within the ophthalmology department.

Authors: Tarno Mamane , Dan-Baki Abdoul Azizou Oumarou
Published: January 2025

Objectif : L’objectif de cet article est d’analyser le rôle de l’agriculture dans le processus de transformation structurelle en Afrique de l’Ouest. 
Conception/méthodologie/approche : Pour ce faire, nous utilisons un modèle de panel à effet aléatoire avec les données de la Banque mondiale et de la CNUCED de 16 pays sur la période 1980–2018. 
Résultats : Les résultats de cette analyse montrent que la valeur ajoutée agricole et l’indice de capacité productive sont des accélérateurs puissants de la transformation structurelle des pays d’Afrique de l’Ouest. En revanche, le capital humain, le taux d’emploi agricole et le taux d’alphabétisation des adultes constituent des freins à ce processus. En outre, les IDE (Investissements Direct Étrangers) se sont révélés être un puissant canal de cette dynamique. Globalement, les résultats suggèrent aux gouvernements de veiller à la modernisation du secteur agricole afin de le rendre plus compétitif et de concentrer les investissements dans les secteurs à forte productivité.
Originalité/valeur : Enfin, ces résultats exhortent les décideurs à créer un environnement propice à une mobilisation accrue et soutenue des IDE, tant donné que, associés à l’emploi agricole, ils amplifient significativement la transformation structurelle.

Os Dentistas e suas Trajetórias no Campo Burocrático Estadual
Authors: De Santana Sisse Figueredo , Chaves Sonia Cristina Lima
Published: January 2025

Objetivo: Este estudo caracterizou as trajetórias sociais e disposições dos coordenadores, técnicos e dirigentes do campo burocrático estadual de saúde bucal em dois estados brasileiros, além de um consultor em saúde bucal do Ministério da Saúde. Método: Realizou-se um estudo exploratório de abordagem qualitativa, a partir das categorias agente, disposições e campo, desenvolvidas pelo sociólogo francês Pierre Bourdieu. Foram conduzidas quinze entrevistas em profundidade que forneceram informações sobre as trajetórias sociais e profissionais dos entrevistados, bem como seus pontos de vista acerca da atuação da esfera estadual e das condições históricas de possibilidade de implantação da política de saúde bucal no âmbito estadual. Resultados: A maioria graduou-se em instituições públicas, com equilíbrio no grupo estudado em relação à origem social. A inserção no campo burocrático estadual foi influenciada pela disposição voltada ao campo burocrático, inquietação com o serviço público, redução do mercado privado e a expansão do campo da saúde coletiva. A trajetória dos agentes evidenciou uma interseção muito baixa do campo burocrático da saúde bucal com os campos político e científico, além da baixa disposição política dos agentes da burocracia estatal. Há um grupo predominante de mulheres com disposição sanitária movido pelo interesse universal, expressando seu “amor pela clínica e pela saúde pública”. Conclusão: a ambivalência de identidade dentista/sanitarista decorrente da influência exercida pelo campo de origem da odontologia pode dificultar as disposições de luta dos dentistas no interior do campo burocrático estadual.

Authors:   Assistant to Deputy of the State Duma of the Federal Assembly of the Russian Federation, Kuzmichev Maksim G.
Published: January 2025

Preserving state sovereignty in the development of cryptocurrencies as the newest form of money is extremely
important in the context of the extremely dynamic development of digital technologies. Regulation of cryptocurrency
and virtual currency has become a national security issue. Thus, the lack of crypto regulation leads, as a rule, to the use of
cryptocurrencies in the shadow economy. Full-fledged crypto regulation can significantly hinder innovative development,
primarily in the financial and economic sphere. Therefore, the problem of developing decentralized payment systems in
the digital economy of the 21st century is closely interconnected with the need to preserve state sovereignty.

Authors:   Postgraduate Student of the Department of Legal Regulation of Public Finance of the Institute of Legislation and Comparative Law under the Government of the Russian Federation, Kukushkin Dmitry S.
Published: January 2025

The article attempts to determine the content of the concept of tax administration and the system of its principles.
This is due to the absence in the legislation of a unified and consistent system regulating management relations in the tax
sphere, which gives rise to numerous conflict situations among the parties to tax legal relations. As you know, any system
begins with a concept and basic principles - the principles that underlie this system.
For this reason, the article offers the author’s definition of the concept of tax administration, and also develops a list
of principles of tax administration that should be enshrined in the tax code.

Published: January 2025

Television broadcasts around the world employ specific hashtags to facilitate viewerengagement via social media with program hosts. In the context of news broadcasts, individuals'comments mix with the articles shown on television news, mainly in relation to urban situations. Thesesocial media posts constitute a significant database, as users assume roles similar to those of citizens. The aim of this paper is to scrutinize the posts associated with the hashtags #VcNoJL1 and #VcNoJL2, publishe on the Twitter (X) platform, in the context of the TV news program TV Liberal, broadcast in the State ofPará (Brazil), using the CRISP-DM methodology and data science techniques. Using a statisticalexamination of these publications, a discreet level of engagement was observed among viewers, who arealso users of the aforementioned social media platform. Furthermore, a sentiment assessment of the posts was carried out, revealing that 54% of the comments are negative, 31% are positive and 15% are neutral. The negative comments notably highlight the challenges within municipal public administration, while the positive comments are around commemorative occasions such as Mother's Day and Grandparents' Day. This type of analysis constitutes an important monitoring tool not only for the television program, but also for public administration.

A partir da análise, observamos a predominância de posicionamentos favoráveis e neutros na abordagem do assunto, que foi pautado sobretudo por veículos de mídia e perfis relacionados ao poder público e tematizado a partir da discussão sobre a campanha da vacinação infantil e da politização da vacina. Identificamos também que o assunto despertou a produção de argumentos em torno da segurança e eficácia dos imunizantes, da necessidade de proteger as crianças, da liberdade de decisão das famílias e da interferência de questões políticas no processo de vacinação infantil.
Kalypso: An inspection AUV for aquaculture
Authors: Manos Nikolaos , Kavallieratou Ergina , Vasilopoulos Nikos
Published: January 2025

Kalypso is a 3D-printed underwater robotic system developed to enhance aquaculture management in the Mediterranean Sea, particularly for species such as sea bream, sea bass, carp, and catfish. It functions in two modes: autonomously as an Autonomous Underwater Vehicle (AUV) for routine inspections, and as a teleoperated Remotely Operated Vehicle (ROV) for more complex interventions. In AUV mode, Kalypso detects critical issues such as structural damage to nets, the presence of dead fish, and biofouling or plant growth on net surfaces. In ROV mode, it enables operators to address these challenges directly, including repairing nets, removing debris, and retrieving dead fish. By facilitating proactive maintenance, improving fish welfare, and optimizing resource allocation, Kalypso represents a significant advancement in aquaculture technology. Its innovative use of 3D printing and dual operational modes ensures a cost-effective, flexible, and sustainable solution tailored to the specific needs of Mediterranean fish farms.

Published: January 2025

The objective of this study was to evaluate the proximate composition, microbiological contamination, and levels of heavy metals in water, sediment, and four fish species (catfish (Clarias gariepinus), Nile tilapia (Oreochromis niloticus), snakehead (Parachanna obscura), and marine catfish (Arius gigas)) obtained from the Oluwa River. Water, sediment, and fish samples were collected monthly in the Oluwa River over a period of three consecutive months. The proximate composition, microbial loads, and heavy metal contents of water and fish samples were assessed utilizing established protocols. The proximate composition result shows that the moisture of the fish content ranges from 7.32 to 9.24%, the crude protein ranges from 82.16 to 85.32%, crude fiber ranges from 0.29 to 2.33%, fat ranges from 0.84 to 4.73%, ash ranges from 3.38 to 6.62%, and carbohydrates range from 0.00 to 0.11%. The findings from the analysis of microbial burdens in water and fish demonstrate a statistically significant distinction (P < 0.05) in the counts of Enterobacteriaceae and total viable counts between the chosen samples of fish and water. The average values (mg/L) of heavy metals in the water range between 0.01 ± 0.00 and 0.53 ± 0.01, with no detection of mercury or manganese. The measured values of the parameters fell within the acceptable limits set by the World Health Organization (WHO) (0.05 mg/L), except for lead, which exceeded the limits. The average concentration (mg/L) of heavy metals in sediment was above the permissible limits except for zinc, which fell within the acceptable range. The average values (mg/kg) of heavy metals range from 1.85 ± 1.15 to 31.75 ± 0.00; 0.03 ± 0.02 and 33.21 ± 0.02; 0.02 ± 0.00 and 29.57 ± 0.02; 0.01 ± 0.00 and 23.52 ± 0.02 for P. obscura, C. gariepinus, O. niloticus, and A. gigas, respectively, and were within the maximum permissible limits set by the WHO with the exception of manganese and copper. The concentrations of heavy metals identified in the Oluwa River may not present an imminent or severe risk to fish and human consumers, potentially leading to adverse health effects.
Poezja wspólnototwórcza. O Balladach rzeszowskich Mirona Białoszewskiego
Authors: Renke Hanna
Published: January 2025

Tekst stanowi próbę interpretacji trzech wierszy Mirona Białoszewskiego z cyklu Ballady rzeszowskie (wyd. 1956) w kontekście rozważań na temat powstawania wspólnot. Dla zaproponowanych odczytań Starej pieśni na Binnarową, Średniowiecznego gobelinu o Bieczu oraz Ballady krośnieńskiej ważne są koncepcje Benedicta Andersona i Lawrence’a Venutiego, w perspektywie których analizowane są wybrane aspekty wspólnototwórczych procesów, wpisanych w interpretowane utwory. W toku rozważań nad formowaniem się społeczności (nie tylko czytelniczych), istotne okazuje się pytanie o potencjał literatury jako fundamentu wielowymiarowej wspólnoty – nie bez znaczenia pozostaje również kwestia utopijności podobnej wizji relacji międzyludzkich. Praca nawiązuje do badań nad oralnością tekstów Białoszewskiego, łącząc je z refleksją nad performatywnością: zarówno analizowanych tekstów, jak i samego aktu lektury.
Nowe obciążenia publicznoprawne a zasada zaufania do państwa i tworzonego prawa
Authors: Glumińska-Pawlic Jadwiga , Gwóźdź Tomasz
Published: January 2025

Autorzy tekstu zwracają uwagę na problemy związane z tworzeniem prawapodatkowego w Polsce, szczególnie w kontekście niespełniania przez nowe przepisy standardów konstytucyjnych i proceduralnych – w tym wynikających głównie z zasady demokratycznego państwa prawa. Obecne praktyki legislacyjne prowadzą do spadku jakości prawa podatkowego.W opracowaniu podkreślono wagę analiz i precyzyjności projektów ustaw podatkowych, które mają ułatwiać zrozumienie i jednolite stosowanie prawa, a także przeanalizowano problematykę techniki redagowania tekstów normatywnych, które często nie spełniają standardów komunikatywności i precyzji.Autorzy poruszają także kwestię wprowadzania nowych danin i opłat, takich jak danina solidarnościowa czy opłata cukrowa. Poddają krytyce brak rzetelnej współpracy z ekspertami i praktykami podatkowymi, co skutkuje wprowadzaniem nieprzemyślanych i nieefektywnych rozwiązań podatkowych.Dodatkowo tekst skupia się na analizie konkretnych nowych obciążeń publicznoprawnych, takich jak podatek deszczowy czy opłata od napojów alkoholowych sprzedawanych w opakowaniach do 300 ml. Autorzy zwracają uwagę na ich konstrukcję, cel oraz nieprawidłowości związane z procesem legislacyjnym.W kontekście zmian w podatku dochodowym od osób fizycznych, wynikających z tzw. Polskiego Ładu, w tekście podkreślono, że choć miały one na celu stworzenie bardziej sprawiedliwego systemu podatkowego, to mogą generować dodatkowe obciążenia, zwłaszcza dla osób osiągających najwyższe dochody.Podsumowując, autorzy wyrazili zaniepokojenie jakością tworzenia prawa podatkowego w Polsce, zwracając uwagę na liczne problemy proceduralne, techniczne oraz wprowadzanie nowych obciążeń bez dostatecznej analizy i współpracy z ekspertami.
Współdziałanie w samorządzie terytorialnym w dobie pandemii – skutki w zakresie podatku od towarów i usług
Authors: Owczarczuk Sławomir
Published: January 2025

Zadania publiczne mogą być realizowane przez jednostki samorządu terytorialnego samodzielnie lub poprzez współdziałanie. Z posiadanej przez jednostki samorządu terytorialnego samodzielności oraz podmiotowości podatkowej w systemie VAT wypływają zróżnicowane konsekwencje, zależne od statusu prawnopodatkowego poszczególnych podmiotów, rodzaju i zakresu wykonywanych zadań oraz relacji pomiędzy jednostką samorządu a innymi podmiotami. Przykładowo niektóre związki międzygminne, w przeciwieństwie do gmin, mają status „podatnika VAT zwolnionego” i nie korzystają z prawa do odliczenia podatku naliczonego przy nabyciu towarów i usług. Podobnie dzieje się, gdy podjęte współdziałanie nie ma charakteru rynkowego i działalność określonego podmiotu nie podlega opodatkowaniu podatkiem od towarów i usług. Celem opracowania jest przedstawienie wybranych form współdziałania jednostek samorządu terytorialnego oraz określenie skutków, jakie one wywołały na gruncie podatku od towarów i usług w okresie pandemii, w kontekście konstytucyjnej zasady samodzielności jednostek samorządu terytorialnego.
Zmiany w konstrukcji prawnej składki na ubezpieczenie zdrowotne a zasada solidarności społecznej
Authors: Lenio Paweł
Published: January 2025

Opracowanie dotyczy problematyki zmian w konstrukcji prawnej składki na ubezpieczenie zdrowotne, które weszły w życie w 2022 r. Zmianie uległy przede wszystkim sposób ustalania wysokości podstawy wymiaru składki zdrowotnej u ubezpieczonych, których obowiązkowym tytułem do ubezpieczenia zdrowotnego jest prowadzenie działalności gospodarczej, oraz w przypadku niektórych przedsiębiorców wysokość stawki. Zmiana zasad ustalania podstawy wymiaru składki na ubezpieczenie zdrowotne dla osób prowadzących działalność gospodarczą przez bezpośrednie powiązanie z ekonomicznymi efektami jej prowadzenia wydaje się dobrym rozwiązaniem, które pełniej realizuje zasadę solidarności społecznej jako zasadę ubezpieczenia zdrowotnego. Zdecydowanie niekorzystną dla ubezpieczonego będącego jednocześnie podatnikiem podatku dochodowego od osób fizycznych zmianą jest pozbawienie go możliwości odliczenia części opłaconej składki zdrowotnej od kwoty podatku. Jest to duża zmiana, która w istotny sposób przysłania zmiany w podstawie wymiaru składki na ubezpieczenie zdrowotne.
Opodatkowanie przedsiębiorców podatkami dochodowymi we współczesnych systemach podatkowych a wartości konstytucyjne
Authors: Supera-Markowska Maria
Published: January 2025

Zasady opodatkowania przedsiębiorców podatkami dochodowymi we współczesnych systemach podatkowych podlegają postępującemu zróżnicowaniu, co w szczegól-ności można obserwować w polskim systemie podatkowym. Zróżnicowania te przejawiają się wielością możliwych rozwiązań dotyczących zasad ustalania dochodu jako przedmiotu opodatkowania w podatkach dochodowych oraz odstępowaniem od usta-lania dochodu na rzecz innych wskaźników (lub wprowadzania opodatkowania „uzupełniającego” z użyciem tych innych wskaźników). Celem opracowania jest dokonanie ogólnej oceny w tym zakresie oraz poddanie refleksji, na ile postępujące zróżnicowa-nie zasad opodatkowania przedsiębiorców podatkami dochodowymi we współczesnych systemach podatkowych służy realizacji pewnych konstytucyjnych wartości, w tym zwłaszcza sprawiedliwości, a na ile je narusza.

Published: January 2025

Państwowe fundusze celowe od przeszło 50 lat są stałym elementem publicznej gospodarki finansowej państwa. Są one zasadniczym narzędziem rozliczeń i transferów pozabudżetowych oraz źródłem finansowania zróżnicowanych zadań publicznych. Celem opracowania jest ocena obecnego statusu państwowych funduszy celowych i kierunków zmian dokonywanych w gospodarce funduszowej, ocena zasadności tworzenia nowych funduszy celowych w kontekście realizowanych przez nie zadań publicznych i źródeł ich finansowania, a także analiza zasad i warunków redystrybucji środków publicznych przez dysponentów wybranych funduszy i zasygnalizowanie problemu obchodzenia konstrukcji normatywnej tej instytucji w praktyce funkcjonowania finansów publicznych.

Published: January 2025

This study analyzed the association between smartphone usage time and dietary behavior, demographic characteristics, physical activity, and mental health among adolescents. Data from 101,051 adolescents participating in the 18th (2022) and 19th (2023) Korea Youth Risk Behavior Surveys were analyzed. Participants were classified into two groups based on daily smartphone usage: normal (<5 hours/day) and risk (≥5 hours/day). Adjusted odds ratios (AORs) were calculated using a complex samples logistic regression after adjusting for demographic characteristics. The risk group had lower frequencies of fruit consumption, water intake, and breakfast eating consumption but higher frequencies of sweetened beverage and fast food consumption compared to the normal group (p<0.001). Group consuming sweetened beverages more than five times per week were significantly more likely to experience sadness and despair (AOR= 1.20, 95% CI= 1.10-1.31) and loneliness (AOR= 1.35, 95% CI= 1.25-1.46) compared to those consuming them less than once per week (p<0.001). Similarly, consuming fast food more than five times per week significantly increased the odds of sadness and despair (AOR= 1.40, 95% CI= 1.28-1.54), loneliness (AOR= 1.34, 95% CI= 1.22- 1.47), and generalized anxiety disorder (AOR= 1.49, 95% CI= 1.32-1.68). Additionally, group consuming breakfast only 1-2 times per week had significantly higher odds of sadness and despair, suicidal ideation, suicide planning, suicide attempts, and loneliness compared to those consuming it five times per week (p<0.001). In conclusion, reducing smartphone usage time among adolescents may be an effective strategy not only for fostering healthy dietary habits but also for improving physical and mental health.

Expérimentation de séchoirs solaires à bois de type rustiques en Côte d'Ivoire
Authors: Durand Patrick Y.
Published: January 2025

Le séchage solaire est une méthode alternative de séchage du bois plus efficace que le séchage à l'air mais moins coûteuse que le séchage au four. Un premier prototype de four solaire a été construit par le Laboratoire de Technologie du Bois du C.T.F.T. en Côte d'Ivoire en 1979, avec plusieurs améliorations supplémentaires afin d'augmenter les performances de séchage.L'objectif de cet article est de présenter ce séchoir solaire expérimental de 1 m3, avec sa conception et ses performances thermodynamiques sous climat tropical.Les premiers résultats des expériences de séchage solaire, en référence au séchage à l'air, montrent que ce premier prototype à faible coût est efficace et réduit le temps de séchage de moitié, même pendant la saison des pluies, et en dessous du taux d'humidité d'équilibre.Enfin, des propositions constructives sont faites pour réduire l'énergie électrique des ventilateurs de régulation.
Un nouveau produit énergétique pour les pays en développement. Le bois torréfié
Authors: Doat Jacqueline
Published: January 2025

Il est bien connu que, le bois, le charbon de bois et la biomasse en général constituent les principales sources d'énergie des pays en développement : 60 % en moyenne, mais plus de 90 % dans les régions les plus défavorisées (Sahel, Népal, etc.). C'est d'ailleurs dans ces dernières régions et dans les zones urbaines que la plupart du temps le charbon de bois est préféré au bois pour la cuisson journalière des aliments.Or, la transformation du bois en charbon de bois entraîne une perte considérable du contenu énergétique initial du bois. Les pays du tiers monde perdent ainsi une grande partie de l'énergie potentielle de leurs forêts.Cet article traite des possibilités de production et d'utilisation d'une nouvelle source d'énergie, le « bois torréfié », qui permet de concilier conservation de l'énergie et accumulation des calories par unité de volume.La technique de production du bois torréfié correspond à une pyrolyse partielle et contrôlée du bois. Le rendement pondéral du bois torréfié est d'environ 70 % à 75 % par rapport au bois anhydre, et son rendement énergétique est de 80 % à 86 %.Les caractéristiques et les perspectives d'avenir de cette substance sont indiquées à la lumière des résultats obtenus avec onze essences tropicales.
Formation du coût des bois en grumes de départ chantier à FOB pour quelques essences et itinéraires types
Authors: Estève Jean
Published: January 2025

Cet article propose une synthèse de la séquence de formation du coût des bois en grumes depuis le site forestier jusqu'au quai, pour quelques essences et itinéraires types représentatifs des pays concernés.L'auteur procède d'abord à une comparaison quantitative et qualitative des exportations de grumes dans quatre grands pays exportateurs de la côte africaine : Cameroun, Congo, Côte d'Ivoire et Gabon. La répartition en nombre et en volume des essences exportées révèle que la concurrence se limite à un nombre très restreint d'essences.La deuxième section passe en revue les principaux éléments constitutifs du coût du passage de la grume depuis la forêt jusqu'à la position FOB sur le quai. Ces éléments sont les suivants :- Le coût total de l'exploitation forestière, qui comprend tous les frais des entrepreneurs impliqués jusqu'au moment où les grumes sont chargées sur les camions au débarcadère.- Le coût des grumes livrées au port d'exportation, y compris tous les coûts de transport dans le pays producteur.- Le coût FOB, qui englobe tous les coûts portuaires et les taxes et redevances à l'exportation depuis la réception du bois sur les camions jusqu'à sa prise en charge par le transporteur maritime.La troisième section évalue toutes les composantes des coûts aux principales étapes du voyage du bois depuis le site forestier jusqu'aux ports d'embarquement dans chacun des quatre pays en question.L'article se termine par des comparaisons entre les coûts totaux et la part relative des éléments de coût entre le site forestier et la position FOB. On constate que le transport interne représente de 25 % à 75 % du coût à l'arrivée à la côte, selon la distance, et que les coûts totaux par mètre cube de grumes à l'arrivée à quai varient d'un facteur 1 à 4, selon les pays, les essences, les itinéraires et les distances.
