Authors: Ashari Arif , Nurussolikhin Rizqya Putri Sani , Putri Audyana , Ervin Muhamad , Indra Wardoyo Muhammad Asrori
Published: September 2024

Yogyakarta, a city based on culture, education, and tourism, has different commuting activities from other industrialized cities in Indonesia. On the other hand, the city is also dominated by motorcycles, like most cities in Indonesia and Southeast Asia. The movement of commuters by motorcycle affects the instantaneous air quality. In this paper, the results of an investigation of the spatio-temporal pattern of air quality of commuter routes in the suburbs of Yogyakarta are presented. Data were collected through observation by measuring five air quality parameters and vehicle intensity in 10 commuter routes in Yogyakarta. Data were analyzed using GIS analysis using average nearest neighbour, statistical analysis using simple linear regression, and matching analysis referring to The World Air Quality Index and Vianney and Erfianto (2023), supported by descriptive analysis. There are three critical findings from this study. First, air quality varies spatially and temporally, with differences among commuter routes and travel times. Second, the relationship between passing vehicle intensity and air quality is unique. Some positively correlate with linear, exponential, logarithmic, or polynomial relationship properties. Third, poor air quality tends to be found on main routes with high vehicle intensity. In summary, this study provides new insights into air quality patterns concerning commuter traffic in motorcycle-dominated cities in Indonesia.
Is the Food Insecurity Experiences Scale (FIES) A Valid Tool for Assessing Food Insecurity in Sudan?
Authors: S. Mohamed Abdalla Samar
Published: September 2024

Food insecurity is a widespread issue globally, and the Food and Agriculture Organization (FAO) developed the Food Insecurity Experience Scale (FIES) to measure different levels of food insecurity severity. The FIES includes eight questions that assess people's access to sufficient and quality food. This study aims to examine the reliability and validity of using the FIES as a measurement tool for food insecurity and to provide guidance for policymakers to address hunger and ensure food security in Sudan. A sample of 330 households from the White Nile State in Sudan was chosen to complete the FIES questionnaire. The collected data was then analyzed using descriptive statistics, Alpha Cronbach’s, and exploratory factor analysis (EFA). The FIES results indicate that approximately 33.6% of households are moderately affected by food insecurity, while 37.9% experience severe food insecurity. The Alpha Cronbach’s coefficient confirms that the FIES questions display acceptable internal consistency. Moreover, the EFA results reveal two main components that account for about 60.7% of the total variance in the FIES questions. Consequently, this study recommends the FIES as a reliable and valid tool for assessing food insecurity in Sudan

Published: September 2024

Based on the RTRW of Dharmasraya Regency, the hydrological aspects reveal numerous river basins and relatively gentle slopes, leading to frequent flooding during the rainy season. This study aims to identify flood vulnerability levels in Dharmasraya Regency and develop effective mitigation strategies. Using purposive sampling, data were analyzed descriptively and quantitatively through Overlay and Scoring techniques, categorizing flood vulnerability into three levels: slightly vulnerable (16,037.18 ha), vulnerable (68,982.47 ha), and highly vulnerable (168,920.24 ha). The proposed mitigation strategies include structural approaches such as constructing embankments and evacuation routes, and non-structural approaches like public awareness campaigns and disaster management training. This research contributes to developing more adaptive and context-specific disaster mitigation methods for regions with similar hydrological and topographical characteristics, offering a broader application of mitigation approaches in regional contexts. The findings enrich the literature on natural disaster mitigation in flood-prone areas and guide stakeholders in reducing flood risk in Dharmasraya Regency. AbstrakBerdasarkan RTRW Kabupaten Dharmasraya, aspek hidrologi menunjukkan banyak daerah aliran sungai dan kemiringan landai, menyebabkan banjir sering terjadi selama musim hujan.

Published: September 2024

Ovarian edema is an unusual clinical quiddity, creating a consequence challenge as it is very huge and easily misinterpret as neoplasm. In this case,
a 19-year-teenage girl presented with a right sided localised abdominal pain in addition to episodes of vomiting on and off for past 1 month. On per
abdominal examination, she had a vague mass felt in the right iliac fossa associated with tenderness present in the right iliac fossa, umbilicus and
suprapubic region . MRI revealed Right ovarian mass neoplasm, thickening and twisting of pedicle possibly torsion with cystoglandular
hyperplasia with mild free uid in pelvis. Tumour Markers were done and found to be normal. With the diagnosis of ovarian neoplasm, laparotomy
was performed, and intraoperative frozen section excluded malignancy with differentials suggesting of bromatosis/right ovarian complex
cyst/massive right ovarian edema. The patient underwent unilateral salpingo-oophorectomy. Histopathological report was found out to be Right
ovarian edema. Right ovarian edema should be suspected in women at the adolescent and reproductive age so that these young patients will be
treated by providing fertility preservation options which is mandatory
CASE REPORT ON A PRIMARY GRYNFELTT LUMBAR HERNIA
Authors: Farooque Mohammad , Jain Nitin
Published: September 2024

A weakening in the postero-lateral abdominal wall can lead to the development of lumbar hernia. These defects are usually common in the Petit's
inferior triangle or the Grynfeltt-Lesshaft superior triangle. As it is a rare entity, it is often missed in diagnosis , leading to a delay in management.
We present a case of a 45 year-old male with no previous surgery who presented with a mass in the right lumbar region for last 1 year. The lump
gradually increased in size and caused a vague dragging pain. On Computed tomography, the diagnosis of left Grynfeltt hernia was made. The
patient underwent a laparoscopic mesh repair and had an uneventful postoperative hospital stay. Although it is a rare entity, there should be a high
degree of suspicion of a lumbar hernia while evaluating a case of a lumbar mass. Early diagnosis by computed tomography and management with
open or minimally invasive techniques can prevent future complications.
COMPONDO A ARENA POLÍTICA DE TURISMO A PARTIR DO TERMINAL MARÍTIMO DE PASSAGEIROS DE NATAL – RN
Authors: Silva Júnior Francisco Xavier da , Nóbrega Wilker Ricardo de Mendonça
Published: September 2024

A utilização do turismo enquanto ferramenta de reavivamento de centros históricos tem se tornado uma alternativa para as capitais brasileiras. Dentre os equipamentos disponíveis para impulsionamento do turismo nos centros históricos, os portos emergiram como alternativa as novas demandas por possuírem ligações históricas com as cidades. Com a Copa FIFA 2014, as cidades de Natal, Salvador, Fortaleza e Recife  receberam a implantação dos Terminais Marítimos de Passageiros (TMPs), em seus portos. Os TMPs surgiram para proporcionar uma nova dinâmica ao turismo e centros históricos, abrangendo para além do trânsito de passageiros. O foco dessa análise centra-se no bairro da Ribeira e em específico o TMP do Porto de Natal. Assim, o objetivo desta pesquisa foi compreender o lugar do turismo na constituição da(s) arena(s) política(s) definida(s) para construção e operacionalidade do TMP do Porto de Natal, considerando sua conexão com o bairro da Ribeira. A técnica de análise utilizada foi a aplicação da teoria de Offe (1981, 1984a, 1984b). Como resultado, entendeu-se que é necessário transcender o entendimento de turismo por parte do poder público, devendo encará-lo como um fenômeno complexo e dinâmico que abarca diversos agentes no processo de planejamento e execução. Bem como, os agentes que foram envolvidos nas arenas do TMP encontraram-se aleatórios no campo, com poucas conexões, porém com ideologias aproximadas. Concluiu-se que, com impacto do processo de desvalia do bairro da Ribeira, se averiguou que o TMP se encontra isolado na dinâmica do bairro, enfraquecendo a retomada da relação porto-cidade a partir do turismo.

Introduction. The key step in agent-based modeling of epidemics, which allows researchers to take into account individual characteristics of people, is the creation of an artificial population. The main difficulty of this procedure is finding a balance between the detail of the population description and the computational efficiency of the calculations.
The aim and objectives of the review: Critically analyze and summarize the current evidence on how to create artificial populations; evaluate the limitations and advantages of available approaches in solving various problems in epidemiology.
Materials and methods. An analysis of literature sources devoted to agent-based modeling has been performed. The analysis is focused on algorithms for creating an artificial population with a given level of detail for modeling human respiratory infections.
Results. The approaches to the creation of artificial populations are generalized. The main principles of realization of interaction between agents are revealed: by means of networks of contacts between agents and on the basis of taking into account the movement of agents between locations. The first approach is the most computationally efficient and simple; the second approach allows to better take into account the change in the behavior of agents during the development of the epidemic process.
Conclusion. Agent-based modeling is an optimal tool for selecting the best scenario for epidemic control and investigating the role of individual characteristics of people in the development of epidemics. When creating an artificial population, it is important to include in the model factors that can be targeted for control. A significant limitation is the lack of factual data on population structure, but this can be overcome by using indirect data.
Moeite met maatwerk. Over de omgang met morele vragen bij het bieden van maatwerk in de dagelijkse uitvoeringspraktijk van juridische professionals bij de overheid
Authors: Mein Arnt
Published: September 2024

In deze notitie doe ik verslag van een verkenning van de vraag hoe juridische professionals bij de overheid omgaan met de morele vragen die naar voren komen als zij in hun uitvoeringspraktijk maatwerk willen bieden. Maatwerk Juridische professionals bij de overheid worden al geruime tijd geconfronteerd met de wens maatwerk te bieden als burgers bij de uitvoering van regelgeving en beleid onbedoeld in de knel raken. Dat wil zeggen dat van hen wordt verlangd optimaal recht te doen aan het belang van de burger, gelet op de specifieke omstandigheden van het geval. Het zijn vooral de uitvoerende professionals werkzaam bij uitvoeringsorganisaties van het rijk of bij gemeenten die zich voor deze uitdaging zien gesteld. Deze groep behandelt onder meer aanvragen voor vergunningen en voorzieningen of klachten en bezwaarschriften. Morele vragen Het bieden van maatwerk biedt ontegenzeggelijk kansen. In de eerste plaats voor de burger, die zo beter tot zijn recht zal komen. Maar ook voor de juridische professional, wiens autonomie en invloed wordt verruimd. Tegelijkertijd roept het ook vragen op. Niet alleen in de sfeer van praktische uitvoerbaarheid, maar ook op het gebied van de juridische houdbaarheid. Zo is het arbeidsintensief, lastig beheersbaar en staat het op gespannen voet met het beginsel van rechtszekerheid en rechtsgelijkheid. Meer in het bijzonder roept het bieden van maatwerk morele vragen op. Bijvoorbeeld: hoever ga ik om een rechtszoekende tegemoet te komen? In hoeverre wijk ik in schrijnende gevallen af van beleid en regelgeving? Wanneer slaat medemenselijkheid om in willekeur of een voorkeursbehandeling? Hoe houd ik het midden tussen doelmatigheid, rechtmatigheid en rechtvaardigheid? Op grond waarvan rechtvaardig ik mijn keuze? Wat betekent dit voor mijn professionele opstelling en integriteit?

Published: September 2024

Tamsulosin HCl is an αq-1 adrenergic receptor antagonist that is primarily used to treat benign prostatic hyperplasia (BPH), a disease defined by an enlarged prostate. The aim of this project is to develop, analyze, and compare the developed formulations to the innovator product (Flomax). The formulations were prepared by integrating Eudragit L100-55 as enteric polymers in various formulations, Drug coat L30D as a sustained release coating polymer, and PEG 6000 as pore forming in distinct quantities. The formulation F8 exhibited %CDR of 98.8%, comparable to the Flomax (innovator product) and the similarity factor (f2) was calculated and found to be 94.3% marking this formulation equivalent to the innovate product. The improved formulation was tested for stability for the 1st month at 40 ± 2°C and 75 ± 5% R_H, as per ICH guidelines. The regression results of the improved formulation led to an inference that F8 indicates first-order kinetics with an estimated regression value of 0.926, and it was concluded that the drug had been released through diffusion mechanism.

A psicose induzida por substâncias (SIS) é um problema clínico relevante devido à sua semelhança com transtornos psicóticos primários. Substâncias como anfetaminas podem causar sintomas psicóticos persistentes, dificultando o diagnóstico. A distinção entre SIS e transtornos primários é desafiadora devido à sobreposição de sintomas. O tratamento geralmente inclui antipsicóticos atípicos e terapias psicossociais, com foco em intervenções precoces para prevenir psicose crônica. Um manejo eficaz exige uma abordagem abrangente para atender tanto às necessidades imediatas quanto às de longo prazo. O objetivo desta revisão sistemática é analisar as abordagens diagnósticas e terapêuticas para a psicose induzida por substâncias, identificando as intervenções mais eficazes para o manejo dessa condição e os principais desafios no diagnóstico diferencial com outros transtornos psicóticos. Foram utilizadas as seguintes bases de dados científicas: Scopus e PubMed, para a seleção dos artigos, como o uso dos unitermos em língua inglesa: “Substance-induced psychosis, Diagnostic approaches, Therapeutic interventions, Differential diagnosis”. Conclui-se que a psicose induzida por substâncias (PIS) é desafiadora para diagnóstico e tratamento devido à sobreposição com transtornos psicóticos primários (TPP). A diferenciação entre PIS e TPP é crucial, mas difícil devido à semelhança dos sintomas. O tratamento geralmente usa antipsicóticos atípicos e combina farmacoterapia com terapias psicossociais. Abordagens emergentes, como intervenções dietéticas e epigenéticas, oferecem novas perspectivas e devem ser acompanhadas para futura validação. Uma abordagem multidimensional, que considere fatores agudos e de longo prazo, é essencial para otimizar os desfechos clínicos e a qualidade de vida dos pacientes.

Authors: University Kaimosi Friends , Kauti Matheaus Kioko , Njuru Peter G.
Published: September 2024

The world's water resources are running out, and this situation is made worse by how quickly people are populating new areas, particularly in developing nations. This has highlighted the critical requirement for prepared action to manage water resources for sustainable development efficiently. Increasing water demands due to climate change, global pressures from urbanization, the already-existing unsustainable variables, and challenges of water supply systems in urban centres pose a challenge in managing water resource effectively. The purpose of the study was to investigate the implication of urban domestic water supply on human health in Machakos Central Ward, Machakos County. Using a Survey Research Design (SRD) both primary and secondary data was collected by use of questionnaires, face-to-face interviews, photography, use of GIS, authors’ observation, and the review of relevant literature in order to (1) document household water supply, (2) determine water quality for the identified categories of households and domestic water supply systems, and (3) Determine how the distribution and coverage of domestic water in a household or home affects the prevalence of water-borne illnesses. The target population was 8,331 households, from which a sample size of 381 respondents was selected. These included households, water vendors and key informants from the Machakos Water and Sewerage Company. Questionnaires (for households and vendors), interview schedules (for water officers and chiefs) and observation schedules were used as instruments for data collection. Data was analysed using Microsoft Excel and Statistical Package for Social Sciences (SPSS) software. The results revealed that the major factors attributed to lower accessibility are shortage of water, high cost of piped water connection, poor coordination, and participation of stakeholders, repairing of old and broken pipes. As a result, nearly half of the dwellers prefer to use alternative sources, exposing them to the risks of water-born diseases

Published: September 2024

Artificial intelligence (AI) is revolutionizing nanotechnology and pharmaceutical research by streamlining drug discovery, optimizing formulations, and personalizing treatments through predictive modelling and data analysis. Without AI, the pharmaceutical industry requires more time due to less effective drug discovery, inefficient clinical trials, and prolonged regulatory processes, resulting in higher costs and delayed treatments1. The integration of AI with nanotechnology and pharmaceutical science is revolutionizing medicine, opening up new possibilities for diagnosis, treatment, and personalized healthcare. It also enhances clinical treatments and identifies new uses for existing drugs, reducing development time and costs2. By leveraging machine learning algorithms, researchers can predict the properties and behaviour of nanomaterials, facilitating the development of nanoparticles that can deliver drugs more efficiently to specific cells or tissues3. AI accelerates nano product development by optimizing nanomaterial design, predicting nanoparticle toxicity, and enhancing nanomedicine formulation. For example, AI has been used to design nanoparticles for targeted drug delivery, improving their efficiency and safety4. AI-enabled nanotechnology can enhance molecular profiling and early diagnosis, refine the design of nanomedicines, and improve their efficacy. By optimizing nanomedicine properties, achieving effective drug synergy, and reducing nanotoxicity, AI facilitates better targetability and accelerates the development of personalized treatments.

Authors: Vinchurkar Kuldeep , Rohit Doke  , Ajay Bhagwat
Published: September 2024

Dear Sir,
Alzheimer's Disease (AD) is an advancing neurological condition marked by diminishing cognitive functions, memory deterioration, and diminished functional skills. It stands as the primary contributor to dementia, encompassing roughly 60-80% of dementia occurrences. Generally affecting the elderly population, particularly those aged 65 and above (10%), and even more prominently in individuals aged 85 and older (30%), the likelihood of developing AD escalates with advancing age. The Key pathological features of AD include the accumulation of amyloid-beta (Aβ) plaques, tau protein build-up, oxidative stress, and immune inflammation. The complexity and unclear nature of AD's pathogenesis make early detection and timely treatment difficult. Nanotechnology, with its distinct physical, electrical, magnetic, and optical properties, shows significant promise in AD detection and treatment. We have explored the recent advancements in applications of nanoparticles (NPs) for AD detection. Additionally, we emphasize significant progress in nanotechnology-based treatment strategies, and challenges and propose future directions for nanotechnology in AD diagnosis and intervention1.

The present work presents a comparative study of iron catalysts supported on mesoporous carbon and silica alumina applied in the Fischer-Tropsch synthesis. X-ray diffraction analysis showed the presence of Fe2O3 (in the form of hematite or magnetite), suggesting that the iron oxide nanoparticles are well distributed and incorporated in the SA and MC supports. The FTS reaction showed that the mesoporous carbon (25Fe/MC) obtained a greater selectivity for heavier hydrocarbons, around C5+ range (⁓ 67.5%) compared to 25Fe/SA (⁓ 47%). Thus, this study opens a new path to produce biofuels from more selective industrial catalysts.

Diante do grande consumo dos combustíveis derivados do petróleo e seu subsequente esgotamento, faz-se necessária a substituição da matriz energética atual por uma matriz renovável, além de mais limpa. A pirólise é uma técnica que converte diretamente determinada biomassa em produtos de alta qualidade energética, podendo estes serem utilizados como hidrocarbonetos renováveis na obtenção de combustíveis renováveis, os chamados biocombustíveis. Essa reação ocorre termicamente na ausência de oxigênio e na aplicação de taxas que variam de 400 °C a 800 °C. É um processo que caracteriza-se pela sua complexidade, onde ocorrem reações simultâneas e sucessivas, em que as longas cadeias dos compostos presentes na biomassa, contendo em geral, carbono, hidrogênio e oxigênio, dividem-se em moléculas menores. Diante do grande potencial da pirólise na geração de biocombustíveis, o presente trabalho teve como objetivo realizar um estudo qualitativo na modalidade de revisão sobre esse processo, fazendo referência aos seus principais métodos reacionais.

Neste trabalho exploratório, estudou-se a hidrotermólise catalítica, usando água como solvente, na presença de fosfato de nióbio suportado com 5% de paládio (5%Pt/NbOPO4) para conversão do óleo de polpa de macaúba em bio-hidrocarbonetos, usando um processo de baixa pressão (10 bar N2) e diferentes proporções biomassa:solvente. O catalisador 5%Pt/NbOPO4 foi o mais promissor para a formação de bio-hidrocarbonetos (11,4%) a partir do óleo de macaúba a 250 ºC, 5h de reação, proporção biomassa:solvente 1:10. Os resultados mostram que a hidrólise do óleo ocorre em grande extensão, como etapa intermediária do processo de desoxigenação.

A alta demanda no consumo de combustíveis fósseis torna necessário encontrar alternativas para sua substituição, como os combustíveis produzidos a partir de biomassa. Entre as biomassas os óleos vegetais despontam como uma das opções e um dos processos de conversão possível é a pirólise. Diante disto, este trabalho propõe a utilização de zeólita H-Beta impregnada com molibdênio, como catalisador, a fim estudar a cinética da degradação térmica do óleo de fritura e posterior aplicação no processo de pirólise. Então, o estudo cinético do óleo de fritura, na ausência de catalisadores e com Mo/H-Beta, foi realizado por meio de dois modelos com métodos integrais livres: Flynn-Wall-Ozawa (FWO) e Kissinger-Akahira-Sunose (KAS) sendo determinada a energia de ativação (Ea) com valores de 190,70 e 211,64 kJ.mol-1 para o óleo de fritura e 144,33 e 162,48 kJ.mol-1, nos respectivos métodos.

O objetivo do presente artigo é realizar uma análise do sistema de governança da produção de combustíveis sustentáveis de aviação no Reino Unido. Para isso, realizamos um mapeamento dos stakeholders. A metodologia elencada foi a leitura da literatura de análise do processo decisório, bem como relatórios governamentais e organizações internacionais. Foram analisados o arcabouço legal, os interesses das partes envolvidas e as ações pretendidas com em seus roadmaps tecnológicos e nos interesses do mercado produtivo. Compreendemos que, atualmente, os investimentos em pesquisa e desenvolvimento estão concentrados na criação de instalações utilizando processos de gaseificação e Fischer-Tropsch (FT) para conversão de resíduos em SAF. Os resultados parciais indicam que dentre as políticas regulatórias há um mandato de SAF até 2025 no país, que incluiu de forma inovadora as emissões de gás carbônico na meta de net zero até 2050 pelo carbon budget de 2033-2037.

O óleo de coco foi cotado como uma excelente matéria-prima para a produção de bioquerosene, pois sua composição possui elevada concentração de ácidos saturados que estão dentro da faixa de cadeia hidrocarbônica deste biocombustível. Dessa forma, este trabalho avaliou a sintese e obtenção do catalisador SBA-15 com 1% e 5% de metal níquel, como também a realização do estudo térmico e pirólise termica e termocatalítico do óleo de coco. Com base nos resultados, foi verificado que o suporte catalítico foi obtido de acordo com o reportado na literatura e a inserção do metal não interferiu na sua estrutura. No estudo térmico foi observado que com o aumento da taxa de aquecimento nem todos os pontos analisados estão de acordocom o reportado na literature. Do processo pirolítico foi obtido rendimento de bio-óleo de 40 a 69% , gás de 30 a 57%, 1,33% de água com o catalisador SBA-15 5% Ni e máximo resíduo de 1,48%. A faixa de hidrocarboneto predominante nos bio-óleos foi o querosene com presença de 42 a 61% de ácidos carboxílicos e aproximadamente 23% de hidrocarbonetos no bio-óleo obtido na presença dos catalisadores, indicando que os catalisadores obtiveram atividade desoxigenante em cerca de 23%.

Na busca por fontes alternativas ao petróleo para obtenção de combustíveis, o uso de biomassa residual tem ganhado cada vez mais atenção, principalmente por seu baixo custo, ampla disponibilidade e por não concorrer com o setor de alimentos. Os biocombustíveis drop-in são foco de pesquisas e desenvolvimento por sua compatibilidade com os combustíveis fósseis, além da mitigação de carbono pelo ciclo de vida de suas matérias-primas, podendo ser obtidos por craqueamento e desoxigenação. No presente estudo, é realizada a pirólise térmica do óleo de fritura (OFT) com faixa de temperatura de 350-550 °C, a 10 °C/min e tempo de permanência de 5 min a cada rampa. O OFT já tem apresentado um bom potencial para produção de biocombustíveis líquidos, apesar de seu elevado nível de acidez. Os rendimentos de pirólise são de 84,64% de bio-óleo, 14,89% gases e 0,47% de biocarvão, tais resultados sendo influenciados pelas condições utilizadas. O alto teor de produtos líquidos pode estar associada a umidade da biomassa, oriundas dos diversos processos de fritura de alimentos, além da reação de desidratação durante a pirólise e temperaturas que favorecem a quebra de moléculas maiores, produzindo moléculas de menores pesos molecular.
AVALIAÇÃO DE ROTA DE PRODUÇÃO DE ELETROCOMBUSTÍVEL PARA AVIAÇÃO UTILIZANDO ELETRICIDADE SOLAR FOTOVOLTAICA E DIÓXIDO DE CARBONO CAPTURADO DO AR

Este trabalho avaliou uma rota para produção de querosene de aviação eletrocombustível. A rota estudada utiliza geração solar fotovoltaica para abastecer a eletrólise, formando o gás hidrogênio. A tecnologia de captura direta do dióxido de carbono do ar (DAC) via absorção foi proposta para fornecer este outro gás. Estes gases participam, então, de uma etapa de síntese, cuja principal unidade é a síntese de Fischer-Tropsch. Os resultados mostram que a síntese deste combustível em quantidades consistentes com a produção do combustível fóssil por refinarias brasileiras é inviável, visto que requer significativas capacidades instaladas de equipamentos e grandes áreas e, ainda, leva à coprodução de grandes quantidades de cloro. Desta maneira, o potencial de produção deste eletrocombustível é limitado pela disponibilidade de área e pela existência de mercados consumidores que possam absorver o cloro coproduzido. Assim, conclui-se que a rota estudada é uma oportunidade de nicho para a produção de eletrocombustíveis.
