Jurnal Penelitian Pengelolaan Daerah Aliran Sungai 6, no. 1 (April 1, 2022): 77–86. http://dx.doi.org/10.20886/jppdas.2022.6.1.77-86.
Full textAbstract:
Lake Kerinci is one of the 15 national priority lakes. In general, residents in this area carry out agricultural or plantation activities without applying conservation principles, resulting in a decrease in the carrying capacity of the Catchment Area (DTA). In addition, DTA Lake Kerinci has also experienced an increase in population, thus encouraging land-use changes. This study aims to analyze land-use changes in DTA Lake Kerinci. Analysis of land-use change analysis uses Landsat imagery 5 TM for 2009 and Landsat imagery 8 OLI-TIRS for 2019 using the guided classification method (Maximum Likelihood Classification/MLC). The accuracy of the image interpretation results is carried out through the Kappa accuracy test. Interpretation of land-use imagery and classification have relatively high accuracy with a kappa value of 78.67% (good) on land use in 2009, 83.30% (almost perfect) on land use in 2019, with an average Kappa Accuracy (KA) of 79.63%. Land-use changes in Lake Kerinci DTA for the 2009-2019 period experienced a significant increase in the area of dry agricultural land by 13% or 13,151.05 ha and a decrease in primary forest area by 6.76% or 6,834.13 ha.

Full textAbstract:
The lake ice phenology variations are vital for the land–surface–water cycle. Qinghai Lake is experiencing amplified warming under climate change. Based on the MODIS imagery, the spatio-temporal dynamics of the ice phenology of Qinghai Lake were analyzed using machine learning during the 2000/2001 to 2019/2020 ice season, and cloud gap-filling procedures were applied to reconstruct the result. The results showed that the overall accuracy of the water–ice classification by random forest and cloud gap-filling procedures was 98.36% and 92.56%, respectively. The annual spatial distribution of the freeze-up and break-up dates ranged primarily from DOY 330 to 397 and from DOY 70 to 116. Meanwhile, the decrease rates of freeze-up duration (DFU), full ice cover duration (DFI), and ice cover duration (DI) were 0.37, 0.34, and 0.13 days/yr., respectively, and the duration was shortened by 7.4, 6.8, and 2.6 days over the past 20 years. The increased rate of break-up duration (DBU) was 0.58 days/yr. and the duration was lengthened by 11.6 days. Furthermore, the increase in temperature resulted in an increase in precipitation after two years; the increase in precipitation resulted in the increase in DBU and decrease in DFU in corresponding years, and decreased DI and DFI after one year.

Full textAbstract:
Dryland ecosystems are fragile to climate change due to harsh environmental conditions. Climate change affects vegetation growth primarily by altering some key bio-temperature thresholds. Key bio-temperatures are closely related to vegetation growth, and slight changes could produce substantial effects on ecosystem structure and function. Therefore, this study selected the number of days with daily mean temperature above 0 °C (DT0), 5 °C (DT5), 10 °C (DT10), 20 °C (DT20), the start of growing season (SGS), the end of growing season (EGS), and the length of growing season (LGS) as bio-temperature indicators to analyze the response of vegetation dynamics to climate change in the Great Lakes Region of Central Asia (GLRCA) for the period 1982–2014. On the regional scale, DT0, DT5, DT10, and DT20 exhibited an overall increasing trend. Spatially, most of the study area showed that the negative correlation between DT0, DT5, DT10, DT20 with the annual Normalized Difference Vegetation Index (NDVI) increased with increasing bio-temperature thresholds. In particular, more than 88.3% of the study area showed a negative correlation between annual NDVI and DT20, as increased DT20 exacerbated ecosystem drought. Moreover, SGS exhibited a significantly advanced trend at a rate of −0.261 days/year for the regional scale, while EGS experienced a significantly delayed trend at a rate of 0.164 days/year. Because of changes in SGS and EGS, LGS across the GLRCA was extended at a rate of 0.425 days/year, which was mainly attributed to advanced SGS. In addition, our study revealed that about 53.6% of the study area showed a negative correlation between annual NDVI and LGS, especially in the north, indicating a negative effect of climate warming on vegetation growth in the drylands. Overall, the results of this study will help predict the response of vegetation to future climate change in the GLRCA, and support decision-making for implementing effective ecosystem management in arid and semi-arid regions.

Full textAbstract:
Differential thermal analyses (DTA) and thermogravimetric analyses (TGA) of seston, sediments, and sediment trap material from Lake Ontario were generally similar to each other but were strikingly different from those of the green alga Chlorella pyrenoidosa. Coinciding with the principal weight loss of carbohydrate material, the main exothermic reaction for all lake samples began at 200–250 °C and peaked at 345–355 °C. Trap samples varied over the season and samples from the deep traps (178 m) had exotherms which were broader with less energy content than from traps near the bottom of the metalimnion. This trend continued into the sediments. Compounds likely to be found in sediments (cellulose, chitin, and humic substances) were also analysed. The calcium carbonate endotherm which begins near 675 °C distinguishes this compound from the total "ash" content. DTA and TGA can be used to detect changes in composition of lake organic matter during the sediment-forming process.

Full textAbstract:
Differential thermal analyses (DTA) and freeze viability tests were conducted to investigate the biophysics of freezing in floral buds of `Danka' black (Ribes nigrutn L.) and `Red Lake' red currants [Ribe.s sativum (Rchb.) Syrne] sampled from Nov. 1989 through Mar. 1990. Scanning electron microscopy was also used to determine the relationship between floral morphology and the freezing characteristics of the buds. Floral buds had multiple abrupt low-temperature exotherms (LTEs) and one or two broad LTEs in DTA tests. Abrupt LTEs from DTA were associated with apparent injury to the inflorescence in viability tests. The number of LTEs did not correspond to the number of racemes or flowers per bud, indicating that several flowers froze simultaneously. DTA experiments conducted in Dec. 1990 revealed that the broad exotherm detected between - 14 and - 20C in `Danka' samples resulted from freezing of supercooled water in the outer nonliving region of the periderm of cane tissue attached to the bud.

The Menjer lake is the main source for Hydroelectric Power Plant of the PLTA Garung. Information about the water balance and the potential of existing water resources in the Menjer Catchment Area (DTA) is needed to obtain an efficient operating pattern, the sustainability of the Garung hydropower plant, and good management of the Menjer Lake. The purpose of this study was to estimate the inflow of three main rivers in the Menjer catchment area using HEC-HMS hydrological and water balance approach. Simulated results of the HEC-HMS model shows that the average of total the inflows of three main rivers to the Menjer lake in 2017, 2018 and 2019 during rainy season are 0.954 m3/s, 0.944 m3/s, and 1.017 m3/s, and during dry season are 0.820 m3/s, 0.783 m3/s, and 0.80 m3/s, respectively. While the prediction results of the discharge with the equation of the water balance shows that the average of total river inflows to the Menjer lake during rainy season is 2017 is 1.628 m3/s, in 2018 it is 1.579 m3/s, and in 2019 it is 3.296 m3/s and during dry season is 1.893 m3/s in 2017, 1.176 m3/s tahun 2018, and 1.893 m3/s in 2019. These results indicate that the results of discharge modeling with HEC-HMS are smaller than those predicted by the water balance equation. The study concluded that HEC-HMS could be used to predict daily inflows. However, further calibration and validation need to be carried out by recommending installing a river flow monitoring station at each river outlet.Keywords: water balance HEC-HMS, inflow prediction

In Cimahi City, the river water is heavily polluted, and well water is not suitable for drinking water, so to anticipate the lack of clean water, the Environmental Service is planning to revitalize one of the ponds, namely the Cibabat Lake. This study’s purpose is to determine the reservoir’s condition based on water quality and trophic status. The method used for calculating water quality status is the Pollutant Index, which refers to the Decree of the Minister of Environment Number 115 of 2003 with results is 8,450, and will be 8,751 in 2022, with the water quality classified status as moderately polluted. Meanwhile, the method to assess trophic status uses the Carlson Trophic State Index (TSI) method by taking air samples for the parameters Total Nitrogen, Total Phosphate, Chlorophyll-a, and brightness which is included in the hypereutrophic category. The Cibabat Reservoir has been polluted by domestic waste based on the calculation of the potential pollutant load such as BOD, COD, TSS, Total Phosphate and Total Nitrogen in the border area is 2,219,600; 3,051,950; 2,108,620; 11,623; and 108,206 kg/day, respectively. DTA area is 1,886.660: 2,594.158; 1,792.327; 9,905; 91.975 kg/day, respectively. This is influenced by the increasing population each year.

Full textAbstract:
Microalgae blooms are one of the most serious environmental problems that greatly affect the living environment of aquatic organisms. They deplete the oxygen source in the water, seriously depleting the respiratory oxygen source for organisms living in the water body. Some species of microalgae are also capable of producing toxins, typically blue-green algae, poisoning aquatic organisms and causing death, health effects on human life when ingested. This paper presents the results of research on mapping algae concentration distribution to support water quality assessment for Dau Tieng reservoir. Landsat satellite imagery was used for qualitative and quantitative assessment of algae presence in the lake area. Calculation results showed that algae concentration had a linear correlation with the band ratio of the 3-band algorithm (3BDA (2), and was a combination of spectral reflective bands in the green wavelength bands GREEN, RED and near infrared NIR. We simulated the spatial distribution of algae concentrations on the entire lake area on 3 points of time when satellite images had been collected. Result of this study showed that remote sensing technology can be used for monitoring the appearance and change of algae concentration in water, which is an essential measurement for timely providing warnings as well as assisting in monitoring and managing water environment quality to minimize damages to people and the ecosystem.

Parapat is the main gateway to Samosir Island and is often referred to as Parapat Tourism City. The presence of Lake Toba with its natural beauty makes the surrounding area a priority object and tourist attraction (ODTW) in North Sumatra. Currently, the Lake Toba area is designated as the National Tourist Destination (DPU) in North Sumatra. At the beginning of 2020, the world was shaken by the presence of the Covid-19 virus outbreak. The Indonesian government has also acted to contain the spread of Covid-19 by implementing the policy "Enforcement of Community Activities Restrictions Enforcement (PPKM)". The existence of these social restrictions has led to the stagnation of the tourism industry. The state of Indonesia's tourism economy, especially Parapat, remains volatile due to the Covid-19 pandemic. The purpose of this study is to investigate the economic situation of the tourist destinations of Parapat in the Covid-19 pandemic. This study uses a qualitative study with a descriptive approach. The data collection techniques used in this study include observational studies and literature studies. Looking at the economy of the tourism sector based on the WTO's Tourism Baseline Index for tourism destinations, there are three parameters: business investment in tourism, income from the tourism sector, and public spending. According to the survey, in 2020, the Covid-19 pandemic and the government's implementation of the Community Activities Restrictions Enforcement (PPKM) caused the decline of various economic sectors in the tourism industry

O presente artigo aborda o desenvolvimento de uma programação no Excel, voltada para estudantes, professores e profissionais que lidam com a necessidade de um sistema para o cálculo de armadura em lajes maciças retangulares apoiadas no contorno, que tenha baixo custo e que ofereça resultados confiáveis. O desenvolvimento desse sistema deu-se pela utilização da ferramenta Virtual Basic for Application (VBA), a qual já vem inclusa nos módulos avançados do Pacote Office. Para o dimensionamento e determinação das armaduras de lajes maciças, dispôs-se da Teoria de Flexão nas Placas que é formada a partir da Teoria de Kirchhoff supondo material homogêneo, isótropo e elástico linear. Através dessa Teoria, dimensiona-se toda a laje analisando por placas isoladas, utilizando as equações de equilíbrio formuladas pela superposição das soluções de Navier ou Levy, dependendo das condições de contorno e carregamento da laje (ARAÚJO, 2014b). Os resultados obtidos com a programação quando comparados aos estudos realizados foram satisfatórios, configurando-se assim uma ferramenta importante para o auxílio didático.

Dazu zählen auch diabetesbezogene Ängste wie die Hypoglykämieangst. Diese kann zu maladaptiven Verhaltensweisen führen, die sich negativ auf das Diabetesmanagement auswirken. Zudem werden das emotionale Wohlbefinden und die Lebensqualität von Betroffenen eingeschränkt. Das frühzeitige Erkennen von Hypoglykämieängsten durch eine ausführliche Anamnese ist daher bedeutsam. Beim Vorliegen relevanter klinischer Symptome sollte zeitnah eine ambulante oder stationäre psychotherapeutische Behandlung erfolgen. Hierbei sollten die betroffenen Familien in die Lage versetzt werden, die Ängste zu bewältigen und das Diabetesmanagement möglichst unbelastet in ihren Alltag zu integrieren.

The Ndutu cranium is a partial, fragmented, and distorted hominin specimen from the Lake Ndutu site in Tanzania. It was first reconstructed by R. J. Clarke in 1976 and later revisited using now-outdated techniques. Consequently, features such as facial projection, cranial height/length, and cranial flexion are contestable. Here, we present a new virtual reconstruction following a transparent and replicable approach that employs virtual anthropology techniques to reassemble, mirror, digitally align, complete the cranium, and remove the effect of plastic deformation. Before deciding on an approach to align the unarticulated fragments, we tested the effects of symmetrization and the use of surface semilandmarks on the performance of our tool of choice: the digital alignment tool (DTA), developed by A. Profico and colleagues in 2019. Upon completion, we compare our reconstruction to a sample of Pleistocene hominin crania via geometric morphometrics. Test results reveal that DTA performance varies by fragment and that the use of surface semilandmarks bears no statistically significant advantage. We found our reconstruction to boast a more prognate and narrower face with a less flexed cranium overall than previous reconstruction efforts. The shape of the reconstructed cranial vault of Ndutu resulted closest to Sima de los Huesos (SH) 5, while its sagittal profile was most similar to Kabwe’s, lending support to J. L. Arsuaga and colleagues’ 1997 work and to P. Rightmire’s, respectively. We warn that further work is necessary before settling the debate surrounding Ndutu’s phylogeny. However, if our reconstruction hypothesis is held, its inclusion in future morphological studies is granted.

Full textAbstract:
This study examines the mortar materials used in the construction of the walls at the Archaeological Roman Fortification site (Ovidiu, Romania) on the shore of Siutghiol Lake. Several analyses were conducted to determine the mortars’ basic physical properties, mineralogical composition, and microstructural characteristics in order to describe the mortars used in the construction of the Roman fortress. The investigation utilized X-ray diffraction (XRD), energy dispersive X-ray fluorescence spectroscopy (XRF), scanning electron microscopy (SEM-EDAX), and differential thermal analysis (TGA-DTA). The results indicated that siliceous aggregates and lime binders were used in the production of the studied mortars, the structure was constructed in the sixth century, and the raw materials used to construct the site are of local origin. Using the methods mentioned above, there is the possibility of recreating the fortification’s mortar formula using contemporary materials and recommending intervention materials for the preservation of the archaeology of the Roman Fortification. Furthermore, this study opens up many other research opportunities regarding the reuse of mortars extracted from archaeological sites in the rehabilitation process by integrating them into new mortar recipes that can then be tested to compare the results with those obtained from standardized recipes.

ZusammenfassungTraumatische tracheobronchiale Verletzungen stellen eine extrem seltene Entität dar. Im Vergleich dazu etwas häufiger sind iatrogene Verletzungen. Eine Literaturrecherche ergab, dass es für dieses Krankheitsbild eine Vielzahl von Case Reports und Kleinserienvorstellungen gibt. Übersichtsarbeiten sind kaum vorhanden und weisen dann i. d. R. einen geringen Evidenzgrad auf. Eine Ursache hierfür ist das Fehlen einer Klassifikation, um die einzelnen Verletzungen miteinander vergleichen zu können. Lediglich für iatrogene Verletzungen der trachealen Hinterwand gibt es eine Klassifikation, die von den Autoren im Hinblick auf traumatische Tracheobronchialverletzungen modifiziert und erweitert wurde. Diese Klassifikation wurde von den Autoren erweitert, um auch traumatische Verletzungen miteinzubeziehen. Es wird hier eine 3-stellige Klassifikation vorgestellt. Die Graduierung der Verletzung bildet vom peribronchialen Emphysem über die unterschiedlich tiefen Wandverletzungen bis zum subtotalen und kompletten Bronchusabriss das gesamte Spektrum der Verletzungsmuster ab. Zusätzlich wurden in der Klassifikation die anatomische Lage und die Ursache der Verletzung hinzugefügt. Anatomisch wird die Höhe der Verletzungen im Tracheobronchialbaum unterschieden. Die 3. Stelle unterscheidet traumatisch, iatrogen und spontan. Aufgrund der sich aus diesen Parametern ergebenden 3-stelligen Klassifikation ist es möglich, einzelne Fälle in Gruppen zusammenzufügen und daraus Empfehlungen für Diagnostik und Therapie zu entwickeln.

O presente artigo objetiva investigar a importância da educação libertadora em contextos marcados por vulnerabilidade e ausência do Estado, tendo como base a experiência do Acervo da Laje, situado no Subúrbio Ferroviário de Salvador-BA. Em diálogo com estudiosos da educação e do pensamento popular, inscritos no campo das epistemologias do Sul, discutimos o papel da cultura popular (sistematicamente relegada à posição periférica e subalterna), com seu inesgotável repertório de outros saberes, memórias e criações, como via de insurgência e libertação social, de maneira a possibilitar a formação de cidadãos críticos e participativos na sociedade. O foco principal desta pesquisa é investigar a efetividade educacional das ações culturais promovidas pelo Acervo da Laje, que se propõem a compartilhar conhecimentos e experiências junto aos moradores suburbanos, tendo como principal referência existencial a vida dentro do território, sem distinção de formação ideológica, acadêmica ou de qualquer ordem. A pesquisa que resultou neste trabalho é de cunho qualitativo, com abordagem teórico-metodológica fenomenológica, de caráter exploratório. A entrada no campo empírico se deu a partir de um trabalho solicitado numa disciplina como aluno especial, e a partir desse primeiro contato foi realizado o anteprojeto que consolidou minha entrada no programa de mestrado Educação e Contemporaneidade (UNEB).

O objetivo deste artigo é analisar as dimensões do desenvolvimento urbano sustentável na percepção dos habitantes de Imperatriz – Maranhão. Para tanto, a pesquisa valeu-se da abordagem quantitativa e descritiva por meio de uma amostra probabilística, considerando 4,84% de erro amostral e 95% de nível de confiança. O procedimento de coleta de dados se deu por meio de um questionário fechado com base nos conceitos de Barbieri e Lage (2001). O procedimento de análise de dados foi dividido em três etapas: estatística descritiva, KMO e análise fatorial. Por fim, pode-se concluir que a cidade de Imperatriz-MA não está dentro dos princípios de desenvolvimento urbano sustentável pela opinião dos habitantes. Apesar desta conclusão e com base nos dados coletados, é importante evidenciar que a população não é participativa no processo de construção de uma cidade melhor e mais sustentável. Deste modo, para a criação de uma cidade mais sustentável é preciso a participação não só do poder público, mas também da população em geral.

Full textAbstract:
This study aims to propose an industrial-agricultural symbiosis model that applies the closed sloop eco-technical solutions for cassava starch production towards sustainable development. This study applies the AHP method to analyze nine alternatives and determines the best one based on 17 specific criteria for the typical cassava starch production plant in Tay Ninh province. The chosen model has 12 losed sloop solutions and can save about 40% groundwater, hundreds of cubic metre of water for irrigation in agriculture (to meet hundreds of hectares of crops), limit the lack of water in the dry season and water regulation from the Dau Tieng lake and reduce from 19-73% emissions from traffic,... Wastewater after Biogas is diluted in proportion for cassava is 28l wastewater/49l of clean water and the rubber tree is 8,5l of wastewater/7l of clean water and sugar-apple is 20l wastewater/20l of clean water wasto spray as a natural leaf fertilizer, limiting the use of NPK chemical fertilizers. Some indicators of wastewater after treatment show that it is suitable for use as fertilizer but suitable for nutrient development in the soil and increase nitrogen for plant development, reducing the cost of using stimulating fertilizers. In addition, production wastewater with high cyanide levels is also considered to dilute according to certain proportions as natural insecticidal drugs. These results show that industrial-agricultural symbiosis model bring great enviromental benifits for cassava starch industry and can be replicated in the future.

Full textAbstract:
AbstractThe saponite examined occurs as two 0.1 m thick layers in a Pliocene sequence consisting of dolomite and dolomitic marl. To characterize this material, mineralogical and structural analyses (XRD, SEM and FTIR), thermal analyses (DTA, TG) and chemical analyses (ICP-ES) were performed. From XRD patterns of randomly-oriented powder samples, the first basal reflection appears as an asymmetric and broad peak with d001 values varying between 16.55 and 17.32 Å. In oriented and air-dried samples, this reflection occurs between 14.45 and 16.42 Å and is fairly symmetrical with FWHM of 2.7º2θ. Oriented and ethylene glycol-solvated samples produce a rational series of basal reflections, where 001 occurs at ~17.8 Å as an intense, narrow (1.1º2θ) and fairly symmetrical reflection. Upon solvation with glycerol, the 001 reflection shifts to ~18.7 Å.The chemical composition of this saponite is similar to stevensite. However, the structural formula of Na0.114Ca0.013K0.003(Mg2.957Al0.004Fe0.028Ti0.004)(Si3.826Al0.174)O10(OH)2 indicates that vacancies in the octahedral sheet do not exist. The negative layer charge arises nearly entirely from the substitutions in the tetrahedral sheet, with the net layer charge of –0.148, smaller than for common smectites.Due to the XRD characteristics and particularly the layer-charge distribution, it was concluded that this mineral is a Mg-rich saponite with low layer charge. The saponite was formed by direct precipitation in an alkaline lake environment from Mg- and Si-rich solutions at high pH.

Mount Sipiso-piso is an Old Volcanic Mountain and part of the Lake Toba Catchment Area (DTA). The location of the Forest on Mount Sipiso-piso is unique because the site of the Forest is at the top of Mount Sipiso-Piso. The area below the mountain is a dense Forest that stands in the peak area of Mount Sipiso-Piso has a role in maintaining water flows in the Mount Sipiso-Piso area, becoming a place for rainwater absorption, and maintaining ecosystem stability so that erosion or landslides do not occur in vulnerable areas. This study aimed to look at the diversity and evenness of Mount Sipiso-piso Forest vegetation types. Data analysis techniques include Important Value Index (INP), Diversity Index (H'), and Evenness Index (E). The results showed that 20 families and 23 plant species from 1539 individuals were found in the field. The Important Value Index (INP) indicates that different individuals dominate the forest community at each level. The index of the diversity of Mount Sipiso-Piso Forest vegetation is categorized as moderate in the saplings, poles, and trees class and the low category in the undergrowth, woody shrubs, and seedlings class. For the species evenness index, the category is expected in the undergrowth and seedling class, the medium type is in the woody shrub and tree class, and the high sort is in the sapling and pole class.Keywords: Sipiso-Piso Mountain, Forest, Vegetation, Diversity, Evenness.

Full textAbstract:
The largest economic center in Vietnam - Ho Chi Minh City, is facing increasingly serious riverbank erosion, one of the main reasons being the flow. Therefore, in this study, the flow velocity field on the Saigon River section is accurately analyzed in different time intervals with the help of MIKE 11 and MIKE 21 models. The simulation results show that The number of flow velocities in the middle of the river is 3-4 times greater than that of the two banks. However, between high tide and low tide, the flow on both sides of the river is faster than the main flow, especially in the upper part of the winding banks, such as the section from Ben Nghe sluice to Tan Thuan, sewer and river section from An Loi Dong Ward police station to Thu Thiem Bridge 2. The velocity value on the studied river section, in most cases, exceeds the allowable value of the non-erosion velocity of the bed material particles. , riverbanks, as well as suspended sediment particles. Therefore, the erosion process on both sides of the river will occur regularly and continuously, so urgent measures are needed to protect the riverbank. During the operation of the anti-flood sluice, the flow velocity will decrease slightly before sluices also appear as whirlpools. The flow velocity on the Saigon River has a complex distribution and changes from time to time depending on the flood discharge from Dau Tieng Lake and the tidal currents of the East Sea.

Full textAbstract:
The Gaawar Nuer recall a battle called Mut Roal which Deng Laka, the prophet of the divinity DIU, fought against the Twic Dinka and their “Arab” allies. In this battle the Dinka and the Arabs failed to coordinate their movements, were attacked, and were defeated singly. Deng Laka himself is said to have personally killed the “Arab” commander. A number of rifles were captured and placed in a hut at the Dinka shrine of Luang Deng, in recognition of the help received from both the divinity DENG and the Rut Dinka caretakers of the shrine (a number of Rut Dinka fought alongside the Gaawar in this, as in other battles). The battle was of a recent enough date to be recounted in some detail by Nuer and Dinka participants to those British officials who visited the Zeraf valley in the first three decades of this century. Though the name of the “Arab” leader involved was remembered and given, the British were uncertain about the date of the battle and the identity of the opponents, and frequently assumed that they were “slavers” from the days of the Turkiyya, the Turco-Egyptian period (1840-85).This seems to be confirmed by contemporary reports given by Casati and Emin Bey, who each recorded the annihilation of an Egyptian army patrol on the Bahr el-Zeraf (the Giraffe River) in 1885. There are some difficulties in reconciling this date with other evidence concerning floods and the opening of age-sets also mentioned by Gaawar and Dinka oral sources. In this paper I will examine the evidence contained in various orally based accounts collected between 1904 and 1982 and compare them with the few contemporary written accounts we have of battles near the Bahr el-Zeraf in the late nineteenth century. I conclude that the battle of Mut Roal was probably fought against the Mahdists in 1896, rather than against “slavers” in 1885. This conclusion in itself has further implications for our understanding of Arab-Nuer relations, and even Nuer-Dinka relations in the late nineteenth century.

Com a entrada em vigor da NBR 15575 (ABNT, 2013), o desempenho das edificações passou a ter mais destaque no âmbito da construção civil. Entre as exigências trazidas pela norma de desempenho, está o desempenho acústico. Este trabalho tem como objetivo avaliar o custo para o atendimento de cada um dos três níveis de desempenho abordados pela norma (mínimo, intermediário e superior) para o sistema de vedações verticais e o sistema de pisos. Foram determinadas soluções para o atendimento destes níveis e, após, estimados os custos. Entre as soluções para os sistemas de vedações verticais internas, foram analisados dois tipos de materiais: alvenaria e placas de drywall, também avaliados entre si. Os resultados obtidos mostraram um menor custo na solução adotada para o nível superior de desempenho, seguido do nível mínimo e, por fim, o intermediário. Como conclusão, o menor custo do nível superior se deu devido ao tipo de laje adotado na camada estrutural do sistema de pisos ser mais eficiente na redução sonora, porém possuir menor custo. Analisando apenas o sistema de vedações verticais, o aumento de custo seguiu o aumento de eficiência acústica, e a adoção de placas de drywall se mostrou mais econômica que a alvenaria.

This study aims to determine the comparison of environmental aspects in the German folklore "The man with the Magic Flute" with “Dewi Liung Indung Bunga” folklore from South Borneo/South Kalimantan. The research approach is a qualitative description with comparative literature study data analysis methods as well as with literary ecology theory. This research proves that the folklore of the two countries has similarities and differences from ecological studies. The results of the study as a representation of nature depicting tropical forests in the story from South Kalimantan and in urban areas in the story from Germany. The local wisdom value of the story from Kalimantan illustrates the belief in giving worship and sacrifice to nature, on the other hand, the story from Germany depicts people who like littering. Examining the heroic elements of the story from Kalimantan was represented by a woman named Dewi Liung Indung Bunga who dared to sacrifice herself for nature and in the story from Germany was represented by a male figure with his power clean the city from rat plague. An analysis of the apocalyptic narrative of a story from Kalimantan shows that humans (Datu Beritau) can receive revelations from God and are vigorous with supernatural nuances and stories from Germany with magical powers that emerge from the sound of flutes that can deceive humans and animals. The research shows that the elements of the apocalyptic environment in both folklore have in common the absence of human consciousness to utilize and protect the environment. This shows that a literary work is part of the natural environment (ecology) of the local community.Penelitian ini bertujuan untuk mengetahui perbandingan aspek lingkungan pada cerita rakyat “Pemuda Berseruling Ajaib” Jerman dengan cerita rakyat “Dewi Liung Indung Bunga” dari Kalimantan Selatan.

Penelitian ini membuktikan bahwa cerita rakyat dari kedua negara tersebut terdapat kesamaan dan perbedaan dari kajian ekologi. Hasil penelitian sebagai beriku representasi alam yang menggambarkan hutan tropis pada cerita dari Kalimantan Selatan dan wilayah kota dalam perbukitan pada cerita dari Jerman. Nilai kearifan lokal cerita dari Kalimantan menggambarkan kepercayaan memberikan sesembahan dan pengorbanan untuk alam dan cerita dari Jerman sebaliknya menggambarkan penduduk yang suka membuang sampah sembarangan. Telaah unsur kepahlawanan cerita dari Kalimantan diwakili oleh perempuan yaitu Dewi Liung Indung Bunga yang berani mengorbankan dirinya untuk alam dan cerita dari Jerman diwakili oleh tokoh laki-laki dengan kekuatannya dapat membersihkan kota dari wabah tikus. Telaah narasi apokaliptik cerita dari Kalimantan menunjukkan bahwa manusia (Datu Beritau) dapat menerima wahyu dari Tuhan dan kental dengan nuansa supranatural dan cerita dari Jerman kekuatan ajaib yang muncul dari suara seruling yang dapat memperdaya manusia dan hewan. Telaah unsur lingkungan apokaliptik dalam kedua cerita rakyat memiliki kesamaan yaitu tidak adanya kesadaran manusia untuk memanfaatkan dan menjaga lingkungan. Hal tersebut menunjukkan bahwa sebuah karya sastra bagian dari lingkungan alam (ekologi) masyarakat setempat.

Full textAbstract:
The mitogenomic evolution of old-world cichlids is still largely incomplete in Western Africa. In this present study, the complete mitogenome of the Cameroon endemic cichlid, Coptodon camerunensis, was determined by next-generation sequencing. The mitogenome was 16,557 bp long and encoded with 37 genes (13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA genes, and a control region). The C. camerunensis mitogenome is AT-biased (52.63%), as exhibited in its congener, Coptodon zillii (52.76% and 53.04%). The majority of PCGs start with an ATG initiation codon, except COI, which starts with a GTG codon and five PCGs and ends with the TAA termination codon and except seven PCGs with an incomplete termination codon. In C. camerunensis mitogenome, most tRNAs showed classical cloverleaf secondary structures, except tRNA-serine with a lack of DHU stem. Comparative analyses of the conserved blocks of two Coptodonini species control regions revealed that the CSB-II block was longer than other blocks and contained highly variable sites. Using 13 concatenated PCGs, the mitogenome-based Bayesian phylogeny easily distinguished all the examined old-world cichlids. Except for Oreochromini and Coptodinini tribe members, the majority of the taxa exhibited monophyletic clustering within their respective lineages. C. camerunensis clustered closely with Heterotilapia buttikoferi (tribe Heterotilapiini) and had paraphyletic clustering with its congener, C. zillii. The Oreochromini species also displayed paraphyletic grouping, and the genus Oreochromis showed a close relationship with Coptodinini and Heterotilapiini species. In addition, illustrating the known distribution patterns of old-world cichlids, the present study is congruent with the previous hypothesis and proclaims that prehistoric geological evolution plays a key role in the hydroclimate of the African continent during Mesozoic, which simultaneously disperses and/or colonizes cichlids in different ichthyological provinces and Rift Lake systems in Africa. The present study suggests that further mitogenomes of cichlid species are required, especially from western Africa, to understand their unique evolution and adaptation.

Timely acquisition of spatial flood distribution is an essential basis for flood-disaster monitoring and management. Remote-sensing data have been widely used in water-body surveys. However, due to the cloudy weather and complex geomorphic environment, the inability to receive remote-sensing images throughout the day has resulted in some data being missing and unable to provide dynamic and continuous flood inundation process data. To fully and effectively use remote-sensing data, we developed a new decision support system for integrated flood inundation management based on limited and intermittent remote-sensing data. Firstly, we established a new multi-scale water-extraction convolutional neural network named DEU-Net to extract water from remote-sensing images automatically. A specific datasets training method was created for typical region types to separate the water body from the confusing surface features more accurately. Secondly, we built a waterfront contour active tracking model to implicitly describe the flood movement interface. In this way, the flooding process was converted into the numerical solution of the partial differential equation of the boundary function. Space upwind difference format and the time Euler difference format were used to perform the numerical solution. Finally, we established seven indicators that considered regional characteristics and flood-inundation attributes to evaluate flood-disaster losses. The cloud model using the entropy weight method was introduced to account for uncertainties in various parameters. In the end, a decision support system realizing the flood losses risk visualization was developed by using the ArcGIS application programming interface (API). To verify the effectiveness of the model constructed in this paper, we conducted numerical experiments on the model’s performance through comparative experiments based on a laboratory scale and actual scale, respectively. The results were as follows: (1) The DEU-Net method had a better capability to accurately extract various water bodies, such as urban water bodies, open-air ponds, plateau lakes etc., than the other comparison methods. (2) The simulation results of the active tracking model had good temporal and spatial consistency with the image extraction results and actual statistical data compared with the synthetic observation data. (3) The application results showed that the system has high computational efficiency and noticeable visualization effects. The research results may provide a scientific basis for the emergency-response decision-making of flood disasters, especially in data-sparse regions.

Through gravimetric determinations, volume resistivity, dielectric spectroscopy, and comparative thermal analysis (TG, DTA and DTG), the interactions between the distilled water and three different types of alkyd-epoxy-melamine, epoxy and polyurethane lacquers were studied. From the experimental determinations it was found that after 700 h of immersion in water at 20 � 2�C the alkyd-epoxy-melamine based lacquer has a maximum water uptake, respectively 1.76%, followed by the epoxy lacquer 1.4% and polyurethane 0.93%. The thermal analysis sugests that because the water retained by the investigated polymers does not change the TG diagrams in the temperature range up to 150 �C, which suggests that the weight increase of the samples during the immersion could be due to some chemical processes between the water and polymer by which the chemistry structure of the polymer changes. Through electrical measurementes one can observe that after the immersion in water (over 700 hours), dielectric loss increases and the volume resistivity (measured in DC) of the investigated lakes decreases, which is explained by the increasing of polar groups (-OH) in the polymer structure. A comparative analysis of the experimental data reveals that in electrical applications the lacquer LS (polyurethane) is superior to the lacquers L-528 (alkyd-epoxy-melamine) and LG (epoxy), because it has no mass losses (structural changes) up to 280�C it has a volume resistivity of about 21 % higher than L-G, and about 300 % higher than L-528, and has water uptake and dielectric loss substantially lower comparing to L-528 and L-G.

Background: Tuberculosis (TB) causes 1.8 million deaths per year globally. TB is now a global priority for research and development. India accounts for >1/4th of global TB burden - 27 lakh out of 1 Crore new cases annually. Many patients with extrapulmonary TB (EPTB) can have pulmonary involvement who can be potentially infectious. Aims and Objectives: This study was undertaken to measure TB positivity and their rifampicin resistance rates in different clinical samples. Sputum TB positivity in EPTB patients was also detected. Materials and Methods: Different samples of clinically suspected patients accounting for 1427 patients for 3 months were tested for TB positivity and Rifampicin resistance by Truenat MTB/RIF assay in R. G. Kar MCH. Biopsy, bones, and tissues were excluded due to lack of facility. Their demographic profile and risk factors were recorded. Results: TB positivity and rifampicin resistance rates in positive samples respectively – sputum (19.01%, 7.86%), pleural fluid (10.78%, 9.11%), bronchoalveolar lavage fluid (4%, 0%), DTA (0%, 0%), gastric lavage (5.26%, 0%), L.N. fine needle aspiration cytology (6.25%, 0%), ascitic fluid (2.13%, 0%), cerebrospinal fluid (5.17%, 0%), urine (2.13%, 0%), and synovial fluid (50%, 0%). Rifampicin resistance was more common among pulmonary samples. Patients with pleural TB had the highest associated sputum TB positivity. Important risk factors were smoking, diabetes, HIV infection, and post-COVID. Overall, the most common age group affected: 21–40 years (38%) including males (64.8%) and females (35.2%). Conclusion: Truenat, sensitive and specific testing with low turnaround time in resource-poor settings is excellent for early diagnosis and prompt treatment of both pulmonary and EPTB. Overall, pulmonary TB had greater rifampicin resistance rates. Smoking, diabetes, HIV infection, and post-COVID infection were associated risk factors.

Setelah itu, peneliti melakukan penafsiran dalam mengalanilisis data yang ada sebagai bagaian dari proses interpretasi. Penafsiran tersebut disajikan dalam narasi deskripti dalam bentuk rincian manajemen media yakni Radar Selatan. Berdasarkan hasil yang diperoleh penrliti, manajemen media Radar Selatan dalam meningkatkan jumlah pengiklan sama saja dengan media lainnya. Hanya saja, ada sedikit strategi yang dan jangkauan yang memiliki perbedan dengan media lainnya. Memasang iklan di Radar Selatan dapat melalui sistem offline atau langsung datang ke kantor atau melalui sistem online dengan mengunjungi situs yang telah disediakan. Dengan keberadaannya di salah satu wilayah bagian selatan Sulawesi Selatan, Radar Selatan kerap menjadi pilihan lembaga, individu dan pemerintah dalam beriklan. Selain karena memiliki pemasaran yang luas, Radar Selatan juga memiliki dta pembaca yang luas sebagaimana data menunjukkan total 15.975 pembaca dari delapan kabupaten/kota. Pembaca merupakan pria dengan jumlah 60% dan wanita dengan jumlah 40%. Jika diklasifikasikan dalam kelompok usia, Radar Selatan banyak digemari oleh rentan usia 31-35 tahun, dari aspek pekerjaan banyak diminati oleh Karyawan/Pegawai negeri/TNI/ Polri sebanyak 35% dan tingkat pendidikan dari kalangan Diploma sebanyak 48%. Oleh karena itu, dengan pelanning hingga controling yang jelas terlihat bahwa sis lain dari manajemen medi Radar Selatan adalah segmentasi yang luas dengan perkembangan pesat meski jauh dari pusat ibu kota Provinsi Sulawesi Selatan.

Solar cells and panels are one of the applications by converting solar energy into electrical energy. However, there exist environmental impacts such as deforestation, microclimate change, soil quality deterioration and migration of wildlife animals when a large amount of land areas are used for solar power plants. One of the solutions to those issues is to build floating solar panels in dams and lakes. We still need to apply large water areas, i.e., oceanic areas for those floating solar cells. Our research group has been studying floating solar cells that are compatible and have the potential to be used in marine environments. This solar cell is made of titanium dioxide photoanode and copper oxides photocathode with seawater electrolyte. Titanium dioxide (TiO2) has been studied for its photocatalytic properties. In this study, the photocatalytic properties of screen printed TiO2 electrodes on stainless steel substrate prepared from different pastes of TiO2 were examined and analysed. Type 329J4L stainless steel with duplex phase structure (ferritic + austenitic) was used as a substrate for TiO2 electrode. At first, the surface of the substrate was polished by sandpaper of 60 grade to form a grid pattern on it. The substrate was then cleaned by acetone in ultrasonic cleaner for 10 minutes and rinsed with distilled water. After that, the substrate was treated with passivation treatment. In this treatment, the substrate was placed in 10 % nitric acid (HNO3) solution at 60 ºC for 30 minutes and then rinsed with distilled water. After passivation treatment, the substrate was printed with TiO2 paste and heat treated at 150 ºC for 60 minutes to form the first layer of TiO2 film on the substrate. The second layer of TiO2 film was formed by screen printing of TiO2 paste followed by heat treatment at 550 ºC for 30 minutes. Finally, the electrode was solder welded and coated with epoxy resin to get ready for the measurement. Different TiO2 pastes were prepared and used for printing on the substrate. The first one was using the purchased TiO2 paste (SP-100 Showa Denko, Japan). The other ones were prepared from TiO2 powder (Sigma-Aldrich). Those pastes were prepared using the certain ratios of TiO2 powder, nitric acid, acetic acid, tritonX-100, and polyethylene glycol. The potential and polarization measurement of the electrodes were carried out in artificial seawater. The irradiation measurement was conducted using a xenon lamp (150 W) with a calibrated wavelength range of 250 nm to 800 nm and output irradiation intensity of 10.5 mW/cm2. Saturated calomel electrode (SCE) was used as a reference electrode and the potentio-galvanostat (SDPS-511U, Japan) was used as the measuring device. Figure 1 shows the potential values over a 2 -hour irradiation testing of two TiO2 electrodes prepared from two different pastes. The optimized TiO2 paste showed higher photopotential performance over time than the merchandized one. The surface and microstructures of the electrodes before and after the measurement were examined by Scanning Electron Microscope (SEM) and the pastes were investigated by Thermogravimetry Differential Thermal Analysis (TG-DTA) and X-ray powder diffraction (XRD). The results are planned to be presented in the upcoming ECS conference meeting. Figure 1

DRIP IRRIGATION WETTING PATTERNS IN A MID FLORIDA SANDY SOIL JOSÉ ALVES JÚNIOR1; WIJE MALLIKAARACHCHIGE BANDARANAYAKE2 E JAMES SYVERTSEN2 1Eng. Agr. Professor Adjunto da Escola de Agronomia (EA) da Universidade Federal de Goiás (UFG), Avenida Esperança, s/n, Campus Samambaia, Goiânia, Goiás, Brasil, CEP: 74.690-900. jose.junior@pq.cnpq.br2Professor and Researcher in University of Florida, IFAS, CREC, Lake Alfred-FL 33850, USA. wijeb@ufl.edu, jmsn@ufl.edu 1 ABSTRACT The wetting pattern of soil under drip irrigation is governed by soil texture, structure, initial water content, emitter spacing, discharge rate and irrigation frequency. Although drip irrigation is not common in central Florida “Ridge soils”, the “advanced citrus production system” can hold a promising future. High frequency, short duration pulses is an important factor to consider for efficient irrigation in this very sandy “Ridge” soils. The objective of this research was to evaluate the water distribution pattern under 1.9, 4.6 and 8.6 L h-1 discharge rate drippers over different wetting durations using three evaluation methods: a) EC5 soil water sensors, b) blue dye tracer, and c) a simple mathematical model developed for sandy soils. Of the three methods, the dye method is labor intensive and time consuming and was used only to evaluate one pulse rate with 3 pulse durations. Soil water sensors, though relatively expensive, gave the most detailed wetting patterns under different combinations of pulse rates and wetting durations. The model overestimated the wetting depth and underestimated the wetting diameter. With the initial soil moisture at 0.055 m3 m-3 and a constant application pressure of 138 kPa, the maximum achievable wetting diameter with increasing pulse rate and pulse duration was limited to 0.75 m. However, the wetting depth increased >1 m with >4.63 L h-1 pulse rate and 3-h duration. Preferential flow was minimal but had little influence on wetting pattern. The best combination was the 4.63 L h-1 emitter with a 3 h pulse that yielded the maximum wetting diameter (0.77 m) and the optimum wetting depth (0.77 m).

BULBO MOLHADO SOB IRRIGAÇÃO POR GOTEJAMENTO EM SOLO ARENOSO NA FLORIDA 2 RESUMO O padrão de umedecimento do solo sob irrigação por gotejamento é regido pela textura do solo, a estrutura, o conteúdo inicial de água solo, espaçamento entre emissores, a vazão do emissor e freqüência de irrigação. Embora, a irrigação por gotejamento não seja comum no centro da Flórida, no "sistema avançado de produção de citros" pode conter um futuro promissor. Alta freqüência, pulsos de curta duração é um fator importante a considerar para irrigação eficiente neste solo arenoso. O objetivo deste trabalho foi avaliar o padrão de distribuição de água em diferentes vazões de gotejadores 1,9, 4,6 e 8,6 L h-1 ao longo de diferentes períodos de molhamento usando três métodos de avaliação : a) sensores de água no solo EC5 , b) corante azul , e c) um modelo matemático simples. Dos três métodos, o método do corante é trabalhoso e consome muito tempo, e por isso só foi utilizado para avaliar uma vazão em 3 diferentes tempos de irrigação. Sensores de água no solo, apesar de relativamente caro, deu os padrões de molhamento mais detalhados sob diferentes combinações de vazão e tempo de irrigação. O modelo superestimou a profundidade molhada e subestimou o diâmetro molhado. Com a umidade do solo inicial de 0,055 m3 m-3 e uma pressão de aplicação constante de 138 kPa, o diâmetro molhado máximo obtido entre as vazões e tempos de irrigação avaliados foi de 0,75 m. No entanto, profundidade molhada ultrapassa 1 m, com 4,63 L h-1 de vazão do gotejador e 3 h de tempo de irrigação. Fluxo preferencial foi mínimo, mas teve pouca influência sobre o bulbo molhado. A melhor combinação foi a vazão de 4,63 Lh-1 com um tempo de 3 h, que produziu o diâmetro máximo de molhagem (0,77 m) e a profundidade de molhagem óptima (0,77 m).

Uma forma de monitorá-los é usando modelos digitais de elevação. Sua precisão razoável tornam o método confiável e de baixo custo. Assim, o estudo objetivou identificar e determinar a capacidade de armazenamento dos reservatórios da região da Fronteira Oeste do Rio Grande do Sul por meio de MDEs. A identificação dos reservatórios deu-se por meio dos dados SRTM e ALOS – PALSAR na geração do TIN (Rede Triangular Irregular). Na sequência foi estimado os valores de volume e área dos reservatórios para a caracterização volumétrica dos mesmos. Tendo estabelecida a distribuição espacial dos reservatórios para a área de estudo, os dados para capacidade volumétrica, área de superfície e profundidade foram transformados em equações log para validação por meio de análise estatística. Os dados derivados dos modelos TIN SRTM e TIN ALOS – PALSAR demonstram o potencial do uso dessas ferramentas na identificação e caracterização de reservatórios de forma detalhada e precisa. Demonstra-se também a confiabilidade da estimativa de área e volume, combinando estimativas de extensão desses reservatórios por meio de dados de radar com relação à área, volume e profundidade.

IDENTIFICATION AND DETERMINATION OF THE STORAGE CAPACITY OF FRESHWATER RESERVOIRS DERIVED FROM SRTM AND ALOS – PALSAR DATA 2 ABSTRACT Freshwater reservoirs are essential sources of storage and supply; however, their quantification and volumetric characterization are neglected due to several factors. One way to monitor them is by using digital elevation models. Its reasonable accuracy makes the method reliable and cost-effective. Thus, the study aimed to identify and determine the storage capacity of reservoirs in the West Frontier region of Rio Grande do Sul through DEMs. The identification of the reservoirs occurred through the SRTM and ALOS – PALSAR data in the generation of the TIN (Irregular Triangular Network). Then, the volume and area values of the reservoirs were estimated for their volumetric characterization. Once the spatial distribution of the reservoirs for the study area was established, the volumetric capacity, surface area, and depth data were transformed into logarithmic equations for validation through statistical analysis. The data derived from the TIN SRTM and TIN ALOS – PALSAR models demonstrate the potential of using these tools in the identification and characterization of reservoirs in a detailed and precise manner. The reliability of the area and volume estimation is also demonstrated by combining estimates of the extent of these reservoirs using radar data in relation to area, volume, and depth. Keywords: water availability, remote sensing, elevation models, lakes.

Este ensaio relata uma experiência de estágio em docência do Ensino Superior na Universidade de São Paulo (USP), e tem como objetivo principal discutir a formação de professores de alemão sob uma perspectiva crítica e decolonial. Essa discussão serve como pano de fundo para uma reflexão sobre o aperfeiçoamento político-pedagógico de uma doutoranda em um estágio de docência sob condições atípicas. A introdução traz um rápido panorama do ensino de alemão no Brasil e das possibilidades para a formação de professores. Em seguida, apresenta-se o funcionamento do curso de Letras com Habilitação em Alemão na USP, com enfoque nas incumbências do bacharelado e da licenciatura. A seção a seguir descreve o Programa de Aperfeiçoamento de Ensino da USP, no âmbito do qual foi realizado o estágio em docência do ensino superior que deu origem a este relato. Então, introduz-se a disciplina de Metodologia do Ensino de Língua Alemã, na qual foi realizado o estágio. Posteriormente, são retomadas as especificidades do ensino universitário ao longo do ano de 2020, caracterizado pela substituição das aulas presenciais pelas remotas, devido à pandemia do covid-19. Por fim, amplia-se a discussão sobre a dimensão política na formação de professores de alemão no Brasil, e as considerações finais defendem que se retome essa dimensão, para que os futuros professores de alemão ajam de maneira cada vez mais autônoma e consciente. Pretende-se, assim, mostrar que a formação docente é feita em etapas diferentes, na graduação e na pós-graduação, e defender que um entendimento melhor desse mosaico é imprescindível para quem se prepara para atuar como formadora de professores.Referências:ALMEIDA FILHO, José Carlos Paes de; FERNÁNDEZ, Gretel Eres Fernández (Orgs.).

Full textAbstract:
Gure gizartean, hidrogenoa gero eta garrantzia handiagoa duen energia-iturria da. Ekoizpen-teknika guztien artean, metanoaren ur-lurrun bidezko erreformatzea da erabiliena. Prozesua hurrengo urratsetan oinarritzen da: gas naturalaren garbiketa, beroketa-prozesua, labe erreformatzailea, ur-lurrunaren bihurketa eta hidrogenoaren bereizketa; labe erreformatzailea elementurik garrantzitsuena izanik. Dena den, teknika honek hainbat erronka ditu, igorritako CO2-ari, katalizatzaileen diseinuari eta energia kontsumoari lotutakoak. Dokumentu honetan, metanoaren lurrun-bidezko erreformatze-prozesuaren deskribapen orokorra aurkezten da, errekuntza-ganberaren, katalizatzaileen, eraginkortasun termikoaren eta labe erreformatzailearen modelizazioaren nondik norakoak azalduz.
